Objectives: The purpose of this article was to familiarize pediatricians with the diagnosis and management of pinworm infestation.

Methods: A search was conducted in August 2023 in PubMed Clinical Queries using the key terms “Enterobius vermicularis,” OR “enterobiasis,” OR “pinworm.” The search strategy included all clinical trials, observational studies, and reviews published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article.

Results: Enterobiasis is a cosmopolitan parasitosis caused by Enterobius vermicularis. It affects approximately 30% of children worldwide and up to 60% of children in some developing countries. Predisposing factors include poor socioeconomic conditions, inadequate sanitation, poor personal hygiene, and overcrowding. Children aged 5 to 14 years have shown the highest prevalence of enterobiasis.. Egg transmission is mainly by the fecal-oral route. Approximately 30 to 40% of infested patients do not show any clinical symptoms of the disease. For symptomatic patients, the most common presenting symptom is nocturnal pruritus ani. The diagnosis of E. vermicularis infection is best established by the cellophane tape test. The sensitivity of one single test is around 50%; however, the sensitivity increases to approximately 90% with tests performed on three different mornings. If a worm is visualized in the perianal area or the stool, a pathological examination of the worm will yield a definitive diagnosis. As pinworms and eggs are not usually passed in the stool, examination of the stool is not recommended. The drugs of choice for the treatment of pinworm infestation are mebendazole (100 mg), pyrantel pamoate (11 mg/kg, maximum 1 g), and albendazole (400 mg), all of the above-mentioned drugs are given in a single dose and repeated in two weeks. Mebendazole and albendazole are both adulticidal and ovicidal, whereas pyrantel pamoate is only adulticidal. Given their safety and effectiveness, mebendazole and albendazole are currently the best available drugs for the treatment of pinworm infestation. For pregnant women, pyrantel is preferred to mebendazole and albendazole. Treatment of all household members should be considered, especially if there are multiple or repeated symptomatic infections because reinfection is common even when effective medication is given.

Conclusion: In spite of effective treatment of pinworm infestation, recurrences are common. Recurrences are likely due to repeated cycles of reinfection (particularly, autoinfection) because of the short life span of adult pinworms. Good personal hygiene, such as frequent handwashing, especially after bowel movements and before meals, clipping of fingernails, avoidance of finger-sucking, nail-biting, and scratching in the anogenital area, are important preventive measures. Treatment of all household members should be considered, especially if there are multiple or repeated symptomatic infections.

This study aimed to investigate the recorded cancer frequency in children and adolescents in Isfahan Province, Iran.

As one of the main reasons for death among children and adolescents is reported as cancer with different prevalence worldwide, therefore, reporting the occurrence of cancers in this population is crucial.

Methods: Information from the years between 2013 to 2015 related to the Surveillance, Epidemiology, and End Results; (SEER) was collected from the Isfahan Cancer Registry. The cancer sites studied were defined according to the International Classification of Diseases and recorded by related topography codes.

Results: Among all 30,465 registered cancers, there were 582 cases (2%) of cancer, including 57% of children and 43% of adolescents. The mean ± SD age of patients was 11.5 ± 5.9 years (Min; 1, Max 19). The top four ranked cancers were (n=264; 45%) comprised of; 1) hematopoietic and reticuloendothelial system (n= 122), 2) secondary and unspecified malignant neoplasm of lymph nodes (n=56), 3) malignant neoplasm of the brain (n=43) 4), thyroid gland (n=43). Death-reported data was associated with 32% of the total population studied. The neoplasm was reported in 174 cases, which was associated with 95% death.

Conclusion: This frequency source of children and adolescents cancers could be used for health strategy. The observed variations in the frequency of different cancers require continuous monitoring and investigation. Therefore, plan of health-system should focus based on greater efforts toward advanced evidence-based drug therapy in Isfahan, Iran.

Objectives: To find out the effect of hand grip exercise in the sustaining patency of peripherally inserted venous catheters among patients in continuous intravenous therapy.

Methods: During the 8 weeks the hand grip exercise was evaluated in patients, who had undergone continuous intravenous infusion through the peripherally inserted venous catheter for at least 3 days. The measurement of data is based on the patient’s socio-demographic Performa, patency checklist, visual infusion phlebitis score and visual analogue scale. The post-test was conducted in both experimental and control groups.

Result: Till the end of the study, 76 participants were taken. On day 3 of the hand grip exercise maximum of 24 (61.5%) PIVC were patent, whereas in control group 5 (13.5%) PIVC were able to maintain their patency. On day 5 of exercise 34 (91.9%) PIVC were replaced with a cause of phlebitis 33(89.2%) in the control group in comparison with the experimental group only 22 (56.4%) lines were replaced with the same cause of phlebitis 24 (61.5%).

Conclusion: Hand grip exercise is important for clients, to reduce the need for the potentially painful process of placing vascular lines and also helps to control costs by reducing the number of devices used for each client and the development of phlebitis.

Objective: The aim of this study is to investigate the clinical presentation, laboratory findings, and comorbidity factors involved in autoimmune thyroid disease among Emirati citizens in the UAE.

Methods: Medical records from Advanced Cure Diagnostic Centers were reviewed in a retrospective study over the period of four years from 2018 to 2022. The patients population included those who attended the Endocrinology Unit and others seen by the rest of the medical staff. Patients were considered to have AITD if they tested positive for thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb), or both. The data collected was evaluated using descriptive analysis to provide a basic summary of the patients sample and dataset. Unpaired t-test was used to compare the mean value of elevated autoantibodies in males and females.

Results: Of the 366 Emirati nationals who were tested for autoimmune thyroiditis, 220 (60%) had an abnormal result for TPOAb and/or TgAb. Among the 220 patients who had an abnormal result for TPOAb and/or TgAb, 188 (85.5%) were females, and 100 patients (45.5%) were in the age group between 31 and 40 years. 42% were in a euthyroid state and 42% presented with hypothyroidism. Only 7% presented with hyperthyroidism, 5% with subclinical hypothyroidism, and 2% with subclinical hyperthyroidism. An analysis of the comorbidity factors revealed 142 (65%) patients with obesity, 82 (37%) with a family history of thyroid disease, 77 (35%) with hyperlipidemia, 14 (6%) with hypertension, and 11 (5%) with diabetes.

Conclusion: This is the first publication intended to address AITD in Emirati citizens. Our findings concur with the international data regarding the prevalence among middle-aged females. Eighty-four percent of the positive patients either presented with no abnormality of their thyroid gland function or with hypothyroidism. With the alarming increase of obesity in the UAE, we found it to be the single most important and preventable comorbidity factor present in 65% of the studied population. This is followed by a family history of first-degree relatives with thyroid disease in 37% of the participants, due to the high rate of consanguineous marriages in the UAE.

Aims: Using clinically collected non-small cell lung cancer (NSCLC) samples, we sought to hypothesize an innovative intact signaling cascade for the disorder.

Methods: We dissected snap-frozen NSCLC tissues along with sibling-paired nearby non-tumorous tissues from 108 NSCLC patients. We measured the expression levels of miR-451/ETV4/MMP13 using qRT-PCR and did a thorough investigation of the molecular mechanism for the signaling axis in NSCLC cell line A549. We also studied the epithelial-mesenchymal transition (EMT) process.

Results: The activity of miR-451 was significantly decreased in NSCLC tissues, while the expression levels of ETV4 and MMP13 were remarkably increased. At the same time, miR-451 levels maintained a declining trend across TNM stage I–III. Inversely, ETV4 and MMP13 increased as the TNM stage increased. The miR-451/ETV4/MMP13 signaling axis was closely associated with prognosis in NSCLC patients. Based on in vitro experiments, ETV4 was a direct targeting factor for miRNA-451. Meanwhile, ETV4 promoted the tumor properties of NSCLC cells by directly activating MMP13. Silencing MMP13 blocked the EMT progress of NSCLC cells.

Conclusion: Overall, we hypothesized an impeccable signaling pathway for NSCLC from a new aspect, and this can offer alternative insights for a better understanding of the disorder.

Methods: To investigate IMPDH2 expression in HB tissues and prognostic significance in HB patients, gene expression profiling interactive analysis (GEPIA) has been adopted. Immunohistochemistry has also helped to validate the protein expression of IMPDH2 in HB tissues. The effect of IMPDH2 overexpression or depletion on the proliferation of Hepatoblastoma cells in vitro has been evaluated by CCK8 assays and colony formation assays. Xenograft tumor growth of mice has been detected. Luciferase reporter assays have been conducted to determine the interaction of IMPDH2 and JunB, which was further asserted by pharmacological inhibition of JunB.

Results: IMPDH2 was highly expressed in HB tissues. Experimentally, the proliferation and colony formation of HuH6 cells were increased by IMPDH2 overexpression. Conversely, genetic inactivation of IMPDH2 impaired the proliferative efficiency and colony-forming rate of HepG2 cells. Besides, the luciferase reporter assay validated IMPDH2 overexpression to be associated with enhanced JunB transcriptional activity, while its activity was diminished in the case of IMPDH2 depletion. JunB inhibitor neutralized the IMPDH2-mediated increased phosphorylation of JunB.

Conclusion: Our findings, thus, suggest that IMPDH2 exhibits its oncogenic role in HB partially via JunB-dependent proliferation.

Methods: Here, using scRNA-sequencing and ATAC-seq on primary chronic myelogenous leukemia (CML) patient samples, combined with bioinformatics analyses, we further examine the heterogeneity of a previously characterized in vitro imatinib-selected CD34-CD38- CML LSC population. We utilized a series of functional analyses, including single-cell metabolomic and Seahorse analyses, to validate the existence of the deepest quiescent leukemia initiators (LI) subset.

Results: Current study revealed heterogeneity of therapy resistant LSC in CML patients and their existence of two functionally distinct states. The most deeply quiescent LI suppress the expression of MC-1, yet are highly dependent on fatty acid oxidation (FAO) for their metabolic requirements and ATAC-seq demonstrated increased chromatin accessibility in this population, all consistent with an extremely primitive, quiescent stemness transcriptional signature. Importantly, the specific CREB binding protein (CBP)/β-catenin antagonist ICG-001 initiates the differentiation of LSC, including LI, decreases chromatin accessibility with differentiation and increasing expression of MC-1, CD34, CD38 and BCR-ABL1, thereby resensitizing them to imatinib.

Conclusion: We investigated the biological aspects related to LSC heterogeneity in CML patients and demonstrated the ability of specific small molecule CBP/β-catenin antagonists to safely eliminate deeply quiescent therapy resistant CSC. These observations may represent an attractive generalizable therapeutic strategy that could help develop better protocols to eradicate the quiescent LSC population.

Methods: This review involved a comprehensive analysis of existing literature and research studies on the pharmacological effects of Lobelia trigona and its bioactive compounds. A bibliography survey was carried out using various electronic databases like Google Scholar, ScienceDirect, Springer, Scopus, PubMed, Wiley, etc., and other offline as well as online academic libraries were also used for the bibliography survey and compilation of data.

Results: Lobelia trigona was found to exhibit diverse pharmacological effects, primarily mediated by bioactive alkaloids, such as lobeline, lobelanidine, and lobelanine. It demonstrated bronchodilator effects with potential applications in respiratory conditions, analgesic and antiinflammatory properties for treating painful and inflammatory conditions, and cardiovascular effects, including vasodilation and hypotensive effects. The alkaloid lobeline was reported to have promising anti-addictive effects, particularly in smoking cessation. Nanocarrier-based formulations have the potential to address limitations, improve dosing schedules, and enhance the pharmacological effects of Lobelia trigona.

Conclusion: Lobelia trigona demonstrates diverse pharmacological effects, primarily attributed to its bioactive alkaloids. It holds promise as a source of medicinal agents for a range of diseases. The potential synergy between the pharmacological effects of Lobelia trigona and nanocarrier technology highlights the significance of nanotechnology in improving Lobelia trigona-based therapeutics. However, further research is warranted to determine the clinical effectiveness, safety, biocompatibility, and long-term effects of nanocarrier-based Lobelia trigona formulations in different disease models.

Case Presentation: We report on a case of KFD that presented 3 weeks after receiving the messenger ribonucleic acid-based coronavirus disease 2019 (COVID-19) vaccine. In this case, we suspected the lesions as COVID-19 vaccination-related lymphadenopathy on the initial ultrasonographic examination.

Conclusion: Through this case report, we highlight that KFD should be considered in the differential diagnosis of patients with axillary lymphadenopathy who have undergone COVID-19 vaccination, as unusual side effects of COVID-19 vaccination have been increasingly reported in the literature owing to the rapid development of various COVID-19 vaccines during the pandemic period. In addition, we emphasize the importance of clinical suspicion in diagnosing KFD due to the fact that axillary involvement of KFD is extremely rare.

Methods: We searched the literature for studies on Google Scholar and PubMed using the keywords “Segmentation,” “Classification,” “medical image,” and “generative adversarial network.” Specifically, the initial search revealed 5423 publications after the removal of duplicated and non-accessible fulltext publications. Then, after the title and abstract screening, 680 underwent full-text screening. Finally, 121 studies were included in our final analysis after full-text screening.

Results: The date range of the studies covered in this review is from January 1, 2017, to the present. After a thorough screening and qualification assessment, 121 studies involving GAN-based applications in seven areas of medical images were included in the final methodological review. These areas included synthesis, classification, segmentation, conversion, reconstruction, denoising, and lesion detection. We further classified and summarized these papers into clinical applications, classification methods, and imaging modalities.

Conclusion: We thoroughly examined the latest research progress of GAN-based medical image augmentation. These techniques effectively alleviate the challenge of limited training samples for medical image diagnosis and treatment models. Furthermore, several critical issues associated with GANs, such as pattern collapse, instability, and lack of interpretability, require attention in future research.

Methods: Ninety patients with head-neck CTA were prospectively selected and randomly divided into a control group and a test group, with 45 patients in each group. The control group was scanned conventionally. With a tube voltage of 100 kVp and detector width of 40 mm, a 70 ml contrast agent was injected at a flow rate of 5.0 ml/s. The test group used GSI. With a tube current fixed of 445 mAs and a detector width of 80 mm, the contrast agent was injected at a flow rate of 3.5 ml/s and 0.6 ml/kg body weight, and the 55 keV virtual monoenergetic images (VMIs) were automatically reconstructed. Finally, the target vessel CT values, background noise (BN), signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), subjective scores, contrast agent dose, CT dose index volume (CTDIvol), and dose length product (DLP) were recorded. The DLP was converted to the effective dose (ED).

Results: The target vessel CT values, BN, SNR, CNR, and subjective scores of the two groups were not statistically significant (all P > 0.05), and the image quality of both groups was the same and met the diagnostic requirements. The contrast agent dose and effective dose (ED) in the test group were approximately 44% and 26% lower than that of the control group, respectively (all P < 0.05).

Conclusion: In head-neck CTA examination, the Revolution CT GSI combined with an 80 mm wide-body detector can reduce the contrast agent dose and radiation dose while ensuring image quality.

Objective: Describe the multidisciplinary approach and the benefits of quality of life and functionality in this diagnosis.

Case presentation: A paediatric patient was diagnosed with an aneurysmal bone cyst located in the cervical spine, which initially manifested with muscle pain, enlargement of the posterior cervical region, and difficulty in performing arcs of movement. He was treated with multidisciplinary management with surgery, embolisation, radiation, and bisphosphonate support.

Conclusion: The purpose of approaching multidisciplinary management helped to improve the accompanying symptoms that prevented our patient from having an active and quality life. However, more successful cases have not been reported to establish the best therapeutic protocol.

Methods: The proposed methodology hinges on a patch antenna operating at 2.4 GHz and a bone phantom housing a simulated fracture, where the antenna is scanned. The collected signals are then processed with Delay-and-Sum (DAS), and Delay-Multiply-and-Sum (DMAS) reconstruction algorithms. The resulting images offer visual insights into the location of fractures.

Results: Through experimentation, the efficacy of the images varies considerably in terms of their capacity for noise and artifact suppression. While DAS exhibits reasonable effectiveness, it suppresses noise and artifacts comprehensively. In contrast, DMAS offers clearer and more precise images of bone fractures.

Conclusion: In summary, the research introduces a cost-effective and non-invasive strategy for detecting bone fractures. By involving a patch antenna at 2.4 GHz, along with image reconstruction algorithms like DMAS and DAS, one can effectively visualize the location of bone fractures. The experimental results highlight the superiority of DMAS over DAS in terms of contrast resolution, making it a highly promising avenue for fracture detection.

Methods: A descriptive cross-sectional study was conducted, and the data was collected using an online survey google forms questionnaire disseminated through social media (Telegram, WhatsApp, and Twitter) as an electronic link. A total of 70 participants responded to the survey directly, and then, the data was analyzed using SPSS (Statistical Package for Social Science).

Results: Regarding the awareness of TI and MI, 64.3% of the participants were aware of TI and 65.7% of MI as safety ultrasound indices; moreover, 74.3% of the participants were aware of the ALARA principle “As Low as Reasonably Achievable.” Participants' knowledge concerning more heat production in pulsed Doppler ultrasound modes was poor (31.5%). Most of the sonographers, i.e, 77.1% were aware of the relationship between the risk of cavitation and MI, and 58.6% of the participants were acquainted with the current FDA output limits. In comparison, 58.6% of the participants were aware of the bioeffects of ultrasound contrast agents. There was no significant correlation between the educational level and the degree of awareness of ultrasound bioeffects and safety (P-value> 0.05).

Conclusion: In this study, it was found that sonographers were aware of the theoretical principles of ultrasound safety indices and the ALARA principle, although they had poor knowledge of ultrasound bioeffects in Doppler mode.

Objective: In response to the challenges posed by the COVID-19 pandemic, we aimed to develop a deep learning model that accurately classifies chest X-ray images, specifically focusing on lung regions, to enhance the efficiency and accuracy of COVID-19 and pneumonia diagnosis.

Methods: We have proposed a novel deep network called “FocusNet” for precise segmentation of lung regions in chest radiographs. This segmentation allows for the accurate extraction of lung contours from chest X-ray images, which are then input into the classification network, ResNet18. By training the model on these segmented lung datasets, we sought to improve the accuracy of classification.

Results: The performance of our proposed system was evaluated on three types of lung regions in normal individuals, COVID-19 patients, and those with pneumonia. The average accuracy of the segmentation model (FocusNet) in segmenting lung regions was found to be above 90%. After reclassification of the segmented lung images, the specificities and sensitivities for normal, COVID-19, and pneumonia were excellent, with values of 98.00%, 99.00%, 99.50%, and 98.50%, 100.00%, and 99.00%, respectively. ResNet18 achieved impressive area under the curve (AUC) values of 0.99, 1.00, and 0.99 for classifying normal, COVID-19, and pneumonia, respectively, on the segmented lung datasets. Moreover, the AUC values of the three groups increased by 0.02, 0.02, and 0.06, respectively, when compared to the direct classification of unsegmented original images. Overall, the accuracy of lung region classification after processing the datasets was 99.3%.

Conclusion: Our deep learning-based automated chest X-ray classification system, incorporating lung region segmentation using FocusNet and subsequent classification with ResNet18, has significantly improved the accuracy of diagnosing respiratory lung diseases, including COVID-19. The proposed approach has great potential to revolutionize the diagnosis of COVID-19 and other respiratory lung diseases, offering a valuable tool to support healthcare professionals during health crises.

The present study aims at analysing the frequency of calcific tendinitis in uncommon sites, in order to fill a gap in knowledge and awareness regarding non-rotator cuff calcific tendinopathy, thus avoiding improper clinical choices and helping to identify this condition.

Methods: This systematic review was conducted following the PRISMA guidelines. We performed a search on Pubmed and Scopus databases concerning atypically sited extra-rotator cuff calcific tendinopathy published since 1950.

Results: The research found a total of 267 articles and 793 non-rotator cuff cases of calcific tendinopathy registered. The spine (213 – 26.86%), foot and ankle (191 – 23.95%), and hip (175 – 22.06%) appeared to be the most common sites of calcific tendinopathy after the rotator cuff, whereas the longus colli C1-C2 (204 – 25.72%), Achilles (173 – 21.81%), and rectus femori (61 – 7.69%) were the most commonly affected tendons.

Conclusion: A better awareness of this condition in several different sites of the body than the rotator cuff could avoid unnecessary choices both in assessment and treatment.

Objective: This study aimed to compare the imaging characteristics of ganglioglioma in children/adolescents and adults to facilitate radiographic diagnosis.

Methods: In this retrospective study, a total of 32 patients were included and divided into two groups: the child/adolescent group (age < 18 years, n=19) and the adult group (age ≥ 18 years, n=13). Various variables were analyzed, including maximum diameter, location, periphery, border, calcification, unenhanced CT attenuation, T1WI, T2WI/FLAIR, and DWI signal intensity, enhancement pattern, degree of enhancement, homogeneity of enhancement, solid/cystic component, peri-tumoral edema, intra-tumoral septa, peri-tumoral capsule, and intra-tumoral hemorrhage.

Results: Most gangliogliomas were situated in the peripheral regions, particularly in the temporal lobe. The majority exhibited hypointense/isointense signals on T1WI and hyperintense signals on T2WI/FLAIR and DWI, with predominantly heterogeneous nodular enhancement. Peri-tumoral edema was significantly less frequent in the child/adolescent group, while marked enhancement was significantly more common in the adult group. There was no significant difference in maximum diameter between the child/adolescent group and the adult group.

Conclusion: Peri-tumoral edema was significantly less prevalent in the child/adolescent group, whereas marked enhancement was significantly more frequent in the adult group. To ensure accurate results, a larger case series should be conducted to validate our findings.

Objective: To propose a motion-resolved 3D pulmonary MRI reconstruction scheme using the sinusoidal representation network (SIREN).

Methods: The proposed scheme learns the registration maps using SIREN to register an averaging image to get the final reconstructions. The learning of the network relies only on the undersampled data from the specific subject. The usage of the network for outputting the registration maps enables a memory-efficient algorithm, as outputting registration maps instead of images only requires small networks. The training of the network based on only undersampled data enables an unsupervised learning scheme, which makes the proposed scheme useful in cases in which fully sampled data is not available.

Results: We compare the proposed SIREN-based motion-resolved reconstruction with two state-of-the-art methods for ten datasets. Both visual and quantitative comparison indicates the better performance of the proposed method.

Conclusion: In conclusion, the use of SIREN for 3D pulmonary MRI reconstruction allows for the efficient and accurate reconstruction of data that has been undersampled.

Objective: The objective of this study is to validate the results of our previous study.

Design: A retrospective study was conducted in two hospitals in the Netherlands.

Patients: All patients that were referred to the internal medicine emergency department between May 2018 and May 2019 with a suspected infection defined as fever (temperature ≥38°C) or hypothermia (temperature <36°C) or CRP ≥100μg/mL.

Main Measures: We defined our primary outcome as the number of newly diagnosed pneumonia by CXR in cases of suspected infection with no obvious site of infection and nor localizing symptoms or signs.

Key Results: We included 1052 patients, of which 106 did not have respiratory signs or symptoms. In this group, none of the CXRs (95% CI 0-2.36%) showed an infiltrate. Combined with our previous study, 176 CXRs were performed in patients with no respiratory signs or symptoms. None (95% CI 0-1.42%) showed an infiltrate.

Conclusion: Our results confirm that a CXR has no diagnostic value in the workup of fever without localizing signs or symptoms.

Objective: To investigate the ultrasonographic features and diagnostic value of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion in children and adolescents.

Materials and Methods: The clinical and ultrasonographic data of 10 patients with renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion confirmed by pathology in our hospital were analyzed retrospectively. The age ranged from 3 to 18 years old, including 7 males and 3 females. The tumor location, size, boundary, echo, hemorrhage, cystic change, calcification, blood flow, lymph node status and metastasis were mainly observed, and the results were compared with the pathological results.

Results: There were 10 masses in 10 cases of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion, including 4 in the right kidney and 6 in the left kidney; the maximum diameter line is 5-23cm; 9 cases had clear mass boundary (90%); 9 masses (90%) showed mixed cystic and solid masses with high echo of solid components, and 1 mass (10%) showed huge multilocular cystic mass with multiple septations; necrosis and cystic changes were seen in all 10 masses (100%); calcification in 5 masses (50%); blood flow signals were seen in the solid components of the mass (100%).

Conclusion: Renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion in children and adolescents are mostly large cystic and solid mixed echo masses, with high echo of solid components, and often accompanied by cystic changes and calcification. Its ultrasonic manifestations have certain characteristics. Color Doppler ultrasound has a certain diagnostic value for this disease.

Objective: This paper covers the general roadmap of the bioprinting process, different kinds of bioinks, and available bioprinters. The paper also includes designing the anatomical structure, which is the first phase of the bioprinting process, and how AI has facilitated this entire process of 3D printing in healthcare and associated applications like medical modelling and disease modelling.

Methods: The process of 3D bioprinting involves meticulous structure designing of the anatomical structure under study, which forms the base of the entire bioprinting process. One of the significant applications of 3D printing in healthcare is Medical Modelling and Disease Modelling, which requires the detection of disease in anatomy and its delineation from the rest of anatomy for meticulous creation of ROI using sophisticated segmentation software(s) for the construction of 3D models of diseased anatomy and healthy anatomical surroundings.

Conclusion: The study concluded that bioprinting is the future of the worldwide organ transplantation crisis. Anatomical accuracy is an important aspect that must be considered while producing 3D models. The reproduction of patient-specific 3D models requires human rights and ethics approval under four principles of ethics in healthcare: autonomy, non-maleficence, beneficence, and justice.

Case Presentation: A 17-year-old girl initially presented with enlarged lymph nodes near the main portal vein of the liver and a large liver tumour. Lesions were identified on the imaging findings obtained via positron emission tomography–computed tomography (CT) scanning, including an abnormal increase of heterogeneous glucose metabolism in the intrahepatic mass, with a maximum standardised uptake value of around 3.2. The CT imaging showed multiple dense shadows in the lesion, while the magnetic resonance imaging indicated a long T1 and a slightly longer T2.

Conclusions: This study summarises the imaging features of CNSETs to provide a reference for diagnosing liver tumours. In addition, the literature on the topics covered was systematically reviewed.

Methods: This retrospective study on 100 patients with LARC analyzed clinical and imaging data that were collected from March, 2018, to March, 2020. Before and after CRT, T2-weighted (T2W), apparent diffusion coefficient (ADC), and contrast-enhanced T1-weighted (ceT1W) data were analyzed. Percent changes of V (%ΔV) and relative SI ratio (%ΔSIR) on different sequences were calculated. After CRT, patients had pathological confirmation as pCR or non-pCR. Data were analyzed using nonparametric tests and receiver operating characteristic (ROC) analysis.

Results: There were 34 pCR and 66 non-pCR patients. Except for ADC-%ΔSIR, the combined parameters and single parameters had a greater decrease in the pCR group. The combination of ADC-%ΔV and T2W-%ΔSIR had the greatest diagnostic value (AUC=0.85,cutoff=0.23%) and the combination of ADC-%ΔV% and ΔSIR had the best accuracy (89%, cutoff=44.11%). Except for T2W-%ΔV and T2W-%ΔSIR, the different sequences had moderate differences in diagnostic performance. The diagnostic performance of combined parameters or single parameters on ADC and T2W was significantly better than those on ceT1W (p<0.01).

Conclusion: All sequences except ADC-%ΔSIR provided reliable predictions of pCR, although ceT1W data had limited usefulness.

Case Presentation: A 19-year-old woman after induction of labor because of severe malformation presented with abdominopelvic mass, laboratory tests revealed significantly elevated serum alpha-fetoprotein (AFP) level and elevated carbohydrate antigen 125 level. Abdomino-pelvic CT showed a cysticsolid mass of 82×152×167mm arising from the right ovary with abundant intratumoral vessels and intense enhancement in the solid part. Further evaluation of ¹⁸F-FDG PET/CT imaging showed significantly increased ¹⁸FDG uptake (SUVmax7.7) by the solid component of the ovarian mass and slight ¹⁸FDG-avid perihepatic effusion. The mass was resected and was confirmed to be the right OYST, After four courses of chemotherapy, the patient was followed up by PET/CT and had a complete metabolic response.

Discussion: ¹⁸F-FDG PET/CT is a useful imaging modality for diagnosis and evaluation of OYST.

Objective: This study aims to assess the impact of breath training on the quality of chest magnetic resonance imaging obtained during free-breathing sequences.

Methods: A total of 68 patients with lung lesions, such as nodules or masses detected via Computed Tomography (CT) examination, were prospectively gathered. They were then randomly divided into two groups: an observation group and a control group. Standard preparation was performed for all patients in both groups before the examination. The observation group underwent 30 minutes of breath training prior to the MRI examination additionally, followed by the acquisition of MRI free-breathing sequence images. The signal intensity (SI) and standard deviation (SD) of the lesion and adjacent normal lung tissue were measured, and the image signal-to-noise ratio (SNR) and contrast signal-to-noise ratio (CNR) of the lesion were calculated for objective image quality evaluation. The subjective image quality of the two groups of images was also evaluated using a 5-point method.

Results: MRI examinations were completed in both groups. Significantly better subjective image quality (edge and internal structure clarity, vascular clarity, breathing and cardiac artifacts, and overall image quality) was achieved in the observation group compared to the control group (P<0.05). In addition, higher SNR and CNR values for disease lesions were observed in the observation group compared to the control group (t=4.35, P<0.05; t=5.35, P<0.05).

Conclusion: It is concluded that the image quality of free-breathing sequences MRI can be improved through breath training before examination.

Objective: This review describes the essential neuroanatomy and neurophysiology of pain nociception and its relation with currently available neuroimaging methods focused on health professionals responsible for treating pain.

Methods: Conduct a PubMed search of pain pathways using pain-related search terms, selecting the most relevant and updated information.

Results: Current reviews of pain highlight the importance of their study in different areas from the cellular level, pain types, neuronal plasticity, ascending, descending, and integration pathways to their clinical evaluation and neuroimaging. Advanced neuroimaging techniques such as fMRI, PET, and MEG are used to better understand the neural mechanisms underlying pain processing and identify potential targets for pain therapy.

Conclusion: The study of pain pathways and neuroimaging methods allows physicians to evaluate and facilitate decision-making related to the pathologies that cause chronic pain. Some identifiable issues include a better understanding of the relationship between pain and mental health, developing more effective interventions for chronic pain's psychological and emotional aspects, and better integrating data from different neuroimaging modalities for the clinical efficacy of new pain therapies.

Methods: A total of 600 patients who were admitted to Beijing You an Hospital were chosen for this prospective study and underwent high-concentration contrast three-dimensional CT imaging of liver blood vessels between April 2021 and December 2021. The patients were divided into two groups using the digital table method, with 300 cases. The control group received conventional nursing intervention, while the research group was provided with a mind map-based predictive nursing protocol. We recorded the image quality of three-dimensional CT imaging of liver blood vessels, satisfaction scores regarding nurse examination guidance, and the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) in both groups.

Results: The research group achieved a perfect rate of 100.00% for the high-quality three-dimensional CT imaging of liver blood vessels, which was noticeably higher compared to the rate of the control group of 98.67%. Patients in the research group expressed higher satisfaction levels regarding the guidance provided by nurses, including their attitude, timeliness, accuracy, and overall satisfaction, compared to the control group. Initially, the two groups had no notable differences in the SAS and SDS scores. However, after the intervention, both groups experienced a significant decrease in SAS and SDS scores, with the research group showing an even more substantial decline.

Conclusion: Through the creation of a mind map-based predictive nursing protocol and its implementation on patients undergoing high-concentration contrast three-dimensional CT imaging of liver blood vessels, it is possible to significantly enhance the quality of CT scans, alleviate feelings of anxiety and depression, increase patient satisfaction with examination guidance by nurses, and effectively decrease the occurrences of contrast agent leakage and allergic reactions to iodine.

Methods: In this study, we proposed a new model called Blend U-Net, which incorporates nested structures, redesigned long and short skip connections, and deep supervisions. The nested structures and the long and short skip connections combined characteristic information of different levels from feature maps in all scales, while the deep supervision learning hierarchical representations from all-scale concatenated feature maps. Additionally, we employed a mixed loss function to obtain more accurate results.

Results: We evaluated the performance of the Blend U-Net against other architectures on the publicly available Lung Image Database Consortium and Image Database Resource Initiative (LIDC-IDRI) dataset. Moreover, the accuracy of the segmentation was verified by using the dice coefficient. Blend U-Net with a boost of 0.83 points produced the best outcome in a number of baselines.

Conclusion: Based on the results, our method achieves superior performance in terms of dice coefficient compared to other methods and demonstrates greater proficiency in segmenting lung nodules of varying sizes.

Case Presentation: Here we report the case of a 69-year-old man who presented with a right atrial mass found incidentally with multimodal imaging findings, including echocardiography, computed tomography (CT), and magnetic resonance imaging (MRI). This case presented with poor enhancement within right atrial mass on dynamic contrast-enhanced CT scan and gadolinium-enhanced first-pass perfusion image of cardiac MRI. After surgical resection, the pathologic diagnosis of cardiac capillary hemangioma was made.

Conclusion: Cardiac hemangioma could be included in the differential diagnosis for cardiac neoplasms demonstrating poor enhancements on CT and MRI scans.

Introduction: The study included the seven most frequently performed investigations, which were carried out on over 1504 patients using digital radiography equipment.

Methods: The X-ray tube's output and exposure parameters were used to calculate the effective dose (ED) and patient entry surface air kerma (ESAK). Additionally, based on these results, conversion coefficients were determined. This study also examined the 75th percentile distributions of ESAK and KAP. The findings of this research were compared with the findings of other researchers throughout the country and the world. The study presents the uncertainty U values, as well as the mean ESAK, KAP, and ED values.

Results: The results of the ESAK, KAP, and ED values were 0.12-5.74 mGy, 0.9-1.84 Gy cm2, and 0.01-0.23 mSv, respectively. As a result, the dosages were much lower than those previously published for the European DRL, national standards, and other studies.

Conclusion: The study concludes that during dose surveys, the importance of detecting and comprehending radiation doses, as well as the proper technique for taking the finest photos possible, can be emphasized to patients in order to assist them in avoiding radioactive particles and radiation exposure.

Methods: An initial assessment was executed using a NEMA phantom to compare image quality engendered by OSEM and HYPER Iterative algorithms. Parameters such as BV, COV, and CRC were meticulously evaluated. Subsequently, a prospective cohort study was conducted on 50 patients, employing both reconstruction algorithms. The study was compartmentalized into distinct acquisition time and dosage groups. Lesions were further categorized into three size-based groups. Quantifiable metrics including SD of noise, SUV_max, SNR, and TBR were computed. Additionally, the differences in values, namely ΔSUV_max, ΔTBR, %ΔSUV_max, %ΔSD, and %ΔSNR, between OSEM and HYPER Iterative algorithms were also calculated.

Results: The HYPER Iterative algorithm showed reduced BV and COV compared to OSEM in the phantom study, with constant acquisition time. In the clinical study, lesion SUV_max, TBR, and SNR were significantly elevated in images reconstructed using the HYPER Iterative algorithm in comparison to those generated by OSEM (p < 0.001). Furthermore, an amplified increase in SUV_max was predominantly discernible in lesions with dimensions less than 10 mm. Metrics such as %ΔSNR and %ΔSD in HYPER Iterative exhibited improvements correlating with reduced acquisition times and dosages, wherein a more pronounced degree of enhancement was observable in both ΔSUV_max and ΔTBR.

Conclusion: The HYPER Iterative algorithm significantly improves SUV_max and reduces noise level, with particular efficacy in lesions measuring ≤ 10 mm and under conditions of abbreviated acquisition times and lower dosages.

Case Report: A 44-year-old female presented with left heel pain that had persisted for over a year and had worsened over the past six months. A mass was found on the Lateral radiograph of the calcaneus, which was diagnosed as an aneurysmal bone cyst. Non-contrast computed tomography (CT) and magnetic resonance imaging (MRI)diagnosed a benign tumor. Based on light microscopy, special stains, and immunohistochemistry, a final diagnosis of diffuse tenosynovial giant cell tumor (D-TGCT) was rendered.

Results: D-TGCT is a slow-growing, infiltrative tumor that can form single or multiple masses outside the joint, and can also involve adjacent jointsmainly affects weight-bearing joints such as the knee, hip, and ankle. However, D-TGCT presents as a calcaneal mass, which poses a diagnostic challenge for all radiologists.

Conclusion: A calcaneal mass exhibiting well-defined borders, focal cortical destruction, a sclerotic rim, and T2WI hypointensity, the possibility of D-TGCT should be considered.

Case Presentation: In this paper, we present the clinical and imaging findings of a 56-year-old female patient with a GT. The patient's main symptoms were increasing abdominal discomfort and pain. After the physical examination, she underwent ultrasound (US) and computed tomography (CT), which showed a large mass at the posterior wall of the stomach, and a teratoma was initially considered. After surgery, pathology confirmed the diagnosis of GT. The patient recovered after surgery and was discharged in good health. To the best of our knowledge, this study is the first reported case of gastric teratoma in an adult woman in the literature.

Conclusion: Gastric teratoma of the adult period is a rare benign neoplasm that may have several complications; therefore, imaging is crucial for diagnosis and accurate treatment management. The aim of this study is to emphasize the value of US and CT in the diagnosis and treatment monitoring of mature gastric teratomas.

Materials and Methods: Using standard T2* relaxation time measurement protocols, in-vivo and ex-vivo MRI data with water and fat nominally in phase or out of phase relative to each other were acquired on a 7 T small animal scanner. Based on a total of 24 different echo times, PDFF maps were calculated in a magnitude-based approach. After identification of the decisive error-prone variables, pixel-wise error estimation was performed by simple propagation of uncertainty. The method was then used to evaluate PDFF data acquired for an explanted mouse liver and an in vivo mouse liver measurement.

Results: The determined error maps helped excluding measurement errors as cause of unexpected local PDFF variations in the explanted liver. For in vivo measurements, severe error maps gave rise to doubts in the acquired PDFF maps and triggered an in-depth analysis of possible causes, yielding abdominal movement or bladder filling as in vivo occurring reasons for the increased errors.

Conclusion: The combination of pixel-wise acquisition of PDFF data and the corresponding error maps allows for a more specific, spatially resolved evaluation of the PDFF value reliability.

Methods: In this retrospective study, a total of 70 patients diagnosed with pulmonary embolism by computed tomography pulmonary angiography (CTPA) from January 2016 to May 2021 in Anhui Chest Hospital were included. Among them, 35 patients with pulmonary embolism combined with pulmonary tuberculosis were set as the study group, and the other 35 patients with pulmonary embolism only were set as the control group. The imaging findings of chest CT examination, the incidence of pulmonary hypertension, the level of N-terminal proto-B-type brain natriuretic peptide (NT-proBNP), and the prognosis of patients were compared between the two groups. The incidence of deep venous embolism was evaluated by ultrasonography of the lower extremity.

Results: In the study group, the median age of patients was 71 years, and the ratio of males to females was 2.5 to 1. In the control group, the median age was 66 years old, and the male-to-female ratio was 2.2 to 1. There were 16 cases (16/35, 45.71%) in the study group and 10 cases (10/35, 28.57%) in the control group with an increased level of NT-proBNP. Pulmonary hypertension occurred in 10 patients (10/35, 28.57%) in the study group and 7 patients (7/35, 20.00%) in the control group. Patients who lost follow-up included 5 in the study group (5/35, 14.29%) and 3 in the control group (3/35, 8.57%). There were 17 cases (17/35, 48.57%) in the study group and 3 cases (3/35, 8.57%) in the control group with pulmonary artery widening, and the difference was significant (P < 0.001). There were 13 deaths in the study group (13/35, 37.14%) and 1 death in the control group (1/35, 2.86%), and the difference was significant (P <0.001).

Conclusion: Special signs of pulmonary artery widening, pulmonary hypertension of varying degrees, and increased levels of NT-proBNP of varying degrees can be found in patients with pulmonary tuberculosis complicated with pulmonary embolism, and the three signs are positively correlated. The mortality of patients with pulmonary tuberculosis complicated with pulmonary embolism is significantly higher than that of patients with pulmonary embolism alone. Pulmonary tuberculosis and pulmonary embolism both occur in the ipsilateral lung, causing clinical symptoms to cover each other, thereby making diagnosis difficult.

Methods: Sixty-four patients with single pulmonary lesions (SPLs) received DCE-MRI at 3.0 T. Of them, 49 cases were diagnosed with lung cancer, and 15 with benign pulmonary nodules (8 inflammatory nodules, 5 tuberculosis, and 2 abscesses). SPLs were quantitatively analyzed to determine the pulmonary lesions-related perfusion parameters, including reflux constant (Kep), volume transfer constant (K_trans), the maximum slope of increase (MaxSlope), extravascular extracellular space volume fraction (Ve), apparent diffusion coefficient (ADC), the initial area in the signal intensitytime curve (IAUGC), and contrast-enhancement ratio (CER). In addition, a Student’s t-test was conducted to calculate statistical significance regarding the quantitatively analyzed perfusion parameters in benign SPLs compared to malignant SPLs. The area under (AUC) the receiver operating characteristic (ROC) curve was studied to investigate the performance of perfusion parameters in diagnosing lung cancer.

Results: Values of K_trans, Kep, Ve, MaxSlope, and IAUGC increased within malignant nodules relative to benign nodules (K_trans: 0.21 ±0.08 vs. 0.73 ±0.40, P = 0.0001; Kep: 1.21 ±0.66 vs. 1.83 ±0.90, P = 0.0163; Ve: 0.24 ±0.08 vs. 0.47 ±0.18, P < 0.0001; MaxSlope: 0.09 ±0.14 vs. 0.28 ±0.29, P = 0.0166; IAUGC: 0.18 ±0.09 vs. 0.55 ±0.34, P = 0.0001). Meanwhile, malignant nodules presented higher ADC than benign nodules (0.0016 ±0.0006 vs. 0.0012 ±0.0003, P = 0.0019). K_trans and IAUGC showed the best diagnostic performance with AUCs [1.0, 95%CI (0.99–1.0); 0.93, 95%CI(0.85–1.0), respectively].

Conclusion: Malignant pulmonary lesions had higher values of K_trans, Ve, Kep, MaxSlope, and IAUGC compared to benign pulmonary lesions. Overall, perfusion parameters of DCE-MRI facilitate discrimination between benign from malignant pulmonary nodules.

Methods: Between May 2021 and January 2022, 397 patients with COVID-19 were included in this retrospective cohort study. All demographic, clinical and laboratory data and chest CT images of patients were retrospectively reviewed. RM-S, V-CAC-S, HS-S, PS-S and C-CT-SS scores were calculated, and their performance in predicting mortality and ICU requirement were evaluated by univariate and multivariable analyses.

Results: A total of 32 (8.1%) patients died, and 77 (19.4%) patients required ICU admission. Mortality and ICU admission were both associated with older age (p < 0.001). Sex distribution was similar in the deceased vs. survivor and ICU vs. non-ICU comparisons (p = 0.974 and p = 0.626, respectively). Multiple logistic regression revealed that mortality was independently associated with having a C-CT-SS score of ≥ 14 (p < 0.001) and severe RM-S category (p = 0.010), while ICU requirement was independently associated with having a C-CT-SS score of ≥ 14 (p < 0.001) and severe V-CAC-S category (p = 0.010).

Conclusion: RM-S, C-CT-SS, and V-CAC-S are useful tools that can be used to predict patients with poor prognoses for COVID-19. Long-term prospective follow-up of patients with high RM-S scores can be useful for predicting long COVID.

Objective: To analyze the diagnostic strategy applied to seven patients with UAPA who were examined and subsequently treated at the National Lung Hospital, Hanoi, Vietnam.

Methods: All seven patients, including three pediatric cases (1, 2, and 14 years old) and four adult cases (21, 26, 44, and 53 years old), had a history of recurrent pneumonia, and the clinical symptoms on admission included cough, progressive dyspnea, chest pain, and fatigue. The patients were initially examined clinically, followed by hematological testing, blood biochemistry testing, and chest X-ray radiology. The results suggested UAPA, so echocardiography and contrast-enhanced chest computed tomography (CT) were performed as soon as practical.

Results: The echocardiographic and CT imaging findings confirmed the suspected diagnosis of UAPA in all seven patients, which was accompanied by congenital heart disease in three patients. Three of the seven patients had mild and medium pulmonary hypertension. All seven patients were treated with drugs, which led to improvement in symptoms.

Conclusion: Frontal chest X-ray provided the initial signs suggesting a diagnosis of UAPA. Subsequent echocardiography and contrast-enhanced chest CT were effective diagnostic tools for fast and accurate confirmation of UAPA.

Methods: We retrospectively reviewed 184 adult patients with 192 intussusceptions. Depending on the location, intussusceptions were classified as enteric, ileocolic, and colonic types. The similarities and differences of clinical presentations, MDCT features, and treatment of three types of adult intussusception were compared. Meanwhile, the three types of intussusceptions were further divided into surgical and conservative groups based on the treatment. Uni- and multivariate logistic analyses were used to identify risk factors for intussusception requiring surgery.

Results: Enteric and ileocolic intussusceptions were mainly presented with abdominal pain (78.46% and 85.71%). Hematochezia/melena (64.29%) was the main symptom of colonic intussusception. On MDCT, ileocolic intussusceptions were longer in length and had more signs of intestinal necrosis (hypodense layer, fluid collection and no/poor bowel wall enhancement) than enteric and colonic intussusceptions. Moreover, it was found that 93.88% (46/49) of ileocolic intussusception and 98.59% (70/71) of colonic intussusception belonged to the surgical group, whereas only 43.06% (31/72) of enteric intussusception belonged to the surgical group. Intussusception length (OR=1.171, P=0.028) and discernible lead point on MDCT (OR=21.003, P<0.001) were reliable indicators of enteric intussusception requiring surgery.

Conclusion: Ileocolic intussusception may be more prone to intestinal necrosis than enteric and colonic intussusceptions, requiring more attention from clinicians. Surgery remains the treatment of choice for most ileocolic and colonic intussusceptions. Less than half of enteric intussusceptions require surgery, and MDCT features are effective in identifying them.

Objective: This study aims to present a detailed review and investigation of schemes considered in medical clinics to identify the AFLD/NFLD coupled problems and present the merit of the Transient Elastography (TE) combined with Fibroscan® practice to identify liver abnormality.

Methods: This research aims to study the clinical significance and the accuracy of TE-supported liver illness screening.

Results: This work aims to collect the recent research works and clinical reports published from 2011 to 2021 from the chosen databases and provide a detailed review using the clinical information discussed in the selected articles.

Conclusion: The essential statistical investigation of the collected data is executed with Review Manager (RevMan®) software, and the significance of the TE is confirmed using the articles supporting a 2x2 contingency table, and each case is evaluated using a p-score and the Region of Convergence (RoC) curve for 95% confidence intervals.

Objective: The primary purpose of this study was to determine whether incidentally detected bone marrow signal changes on MRI performed for various reasons (at the time of admission or during follow-up) are clinically significant.

Methods: We retrospectively evaluated the bone marrow biopsy clinical and laboratory findings of 42 patients with incidental bone marrow signal changes on MRI between September 2016 and January 2020. We also determined whether the patients were diagnosed with malignancy during admission or follow-up.

Results: Of the 42 patients, three (7%) were diagnosed with hematological malignancies during admission, while two were diagnosed with multiple myeloma and one with B-cell acute lymphoblastic leukemia. Of the 42 patients, 35 had a mean follow-up of 40.6 ± 5.3 months. One patient was diagnosed with monoclonal gammopathy of undetermined significance four months after their first admission.

Conclusions: In addition to MRI, detailed clinical and laboratory evaluations should be performed to inform the decision for bone marrow biopsy and exclude hematological malignancy. If there is any doubt, a bone marrow biopsy should be performed. Moreover, since bone marrow signal changes may be a preliminary finding, follow-up of these patients is essential.

However, in the vascular representation, these techniques determine, albeit to different extents, a cut of the weak vessels due to the necessary application of wall filters that cut the disturbing frequencies responsible for artifacts generated by pulsations of the vascular walls and surrounding tissues.

These filters cut a specific range of disturbing frequencies, regardless of whether they may be generated by low-flow vessels.

Recently, a new technology, called Ultrasound Microvascular Imaging (MicroV) has been developed, which is particularly sensitive to slow flows. This new mode is based on new algorithms capable of better selecting the low frequencies according to the source of origin and cutting only the disturbing ones, saving the frequencies originating from really weak flows.

When Ultrasound microvascular imaging is used, the vascular map is more detailed and composed of macro and microvasculature, with more subdivision branches, facilitating the interpretation of the normal and, consequently, the pathological.

This review aims to describe the vascular architecture of the testis with Ultrasound Microvascular Imaging (MicroV) in healthy testis, compared to traditional color/power Doppler, related to normal anatomy.

Objective: We aimed to evaluate benign, borderline, and malignant epithelial ovarian tumors using MRI features and contributed to the preoperative evaluation.

Methods: MRIs of 81 patients (20 bilateral), including 31 benign, 27 borderline, and 23 malignant, who had pelvic imaging between 2013-2020, were evaluated retrospectively. The evaluation was made blindly to the pathology result by two radiologists with MRI scoring and features that we determined. MRI evaluation was performed with T1 TSE, T2 TSE, fat-suppressed T2 TSE, and before and after contrast T1 fat-suppressed and non-fat-suppressed TSE images. The numbers and findings obtained in scoring were evaluated by Chi-Square, ordinal logistic regression, and 2 and 3 category ROC analysis.

Results: The total score varied between 7 and 24. Among the three groups, a significant difference was found in terms of T1, T2 signal intensity (p <0.01), size (p = 0.055), solid area (p <0.001), septa number (p <0.05), ovarian parenchyma (p = 0.001), ascites (p <0.001), peritoneal involvement (p <0.001), laterality (p <0.001), contrast enhancement pattern (p <0.001). On the other hand, no significant difference was found in terms of wall thickness, lymph node involvement and endometrial thickness (p> 0.05). Cut-off values were found as 11.5 and 18.5 in the 3-category ROC analysis performed for the score (VUS: 0.8109). Patients with a score below 11.5 were classified as benign, those between 11.5-18.5 as borderline, and those over 18.5 as malignant.

Conclusion: The differentiation of borderline tumors from benign and malignant tumors by MRI scoring will contribute to the preoperative diagnosis.

Objective: The objective of this study is to interpret the radiological findings of GCL and address the differential diagnosis between GCL and other lymphatic malformations in light of the relevant literature data.

Methods: The sample of this retrospective study consisted of six pediatric patients, four males and two females, diagnosed with GCL based on clinical, radiological, and histopathological findings between 2015 and 2022. The age of the patients at the time of diagnosis and their symptoms at admission were obtained from the hospital database. Radiological imaging findings were evaluated in detail based on the involved systems (thorax, abdomen, and musculoskeletal).

Results: The median age of the sample, 4/6 were male, was 9 years at admission (min. 3, max. 12). The most common symptom at admission was dyspnea, often accompanied by pleural effusion. Bone involvement was the most common extrathoracic finding. Abdominal involvement was primarily asymptomatic, and the spleen was the most frequently involved organ in the abdomen.

Conclusion: The diagnosis of GCL is challenging because of its rarity and overlapping diseases. Whole-body magnetic resonance imaging is a valuable tool as it reveals the typical radiological features of GCL and how far it has spread throughout the body.

Methods: Forty patients who received TCM chest CT scanning were retrospectively collected and divided into four groups according to the tube voltage and sexes. We chose to set up the region of interest (ROI) at the tracheal bifurcation and its upper and lower parts in slice images of the heart, aorta, lungs, paracranial muscles, and female breast, and the SNR of each organ was calculated. We also calculated the corresponding axial volume CT dose index (CTDIvolz) and axial size-specific dose estimate (SSDEz).

Results: The correlation analysis showed that the correlation between the SNR of the slice images of most organs and SSDEz was more significant than 0.8, and that between the SNR and CTDIvol was more significant than 0.7. The simple linear regression analysis results showed that when the sex is the same, the SNR of the same organ at 100kVp was higher than 120kVp, except for the lung. In multiple regression analysis, the result indicated that the determination coefficients of the SNR and SSDEz of the four groups were 0.934, 0.971, 0.905, and 0.709, respectively.

Conclusion: In chest CT examinations with TCM, the correlation between the SNR of each organ in slice images and SSDEz was better than that of CTDIvolz. And when the SSDEz was the same, the SNR at 100 kVp was better than that at 120 kVp.

Methods: The data on age distribution, clinical symptoms at onset, CA125 detection, MRI findings, including tumor volume, structure, diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC) and enhancement, etc., of the patients with stage IA ovarian cancer, who were admitted to Nantong tumor Hospital between 2013 and 2020 were analyzed retrospectively.

Results: Only 11 cases of stage IA ovarian cancer were recorded. The age of patients was 30–67 (average 52) years. The initial symptoms were mostly lower abdominal distension and abdominal pain. CA125 was 90% positive. MRI features 1. Large pelvic mass with a volume range of 23–2,009 cm³ (average 669 cm³). 2. Five cases of cyst type (with plaque-like, papillary, or mural nodule vegetations), two cases of cystic-solid mixed type (with thickened septum or wall), and four cases of solid type. 3. DWI diffusion was limited, and ADC was reduced on all solid components (vegetation, septa, and cyst wall). 4. The solid parts were significantly enhanced on T1-enhanced MRI. 5. There was no metastasis in the pelvic cavity, and a few ascites (negative tumor cells) in three patients.

Conclusion: MRI characteristics of stage IA ovarian carcinomas were large tumors; cystic, cystic-solid, or solid; solid parts limited diffusion on DWI and low ADC; enhancement of the cyst wall, vegetation, and septa; no pelvic metastasis.

Objective: This study investigated the discriminatory power of the stretched-exponential model and fractional-order calculus model parameters for hepatocellular carcinoma versus intrahepatic cholangiocarcinoma in orthotopic xenograft nude mice.

Methods: Prototype orthotopic xenograft models of hepatocellular carcinoma and intrahepatic cholangiocarcinoma were developed using 20 nude mice divided into two groups and separately transplanted with MHCC97H and HUCCT1 cells. Readout-segmented diffusion-weighted imaging with multiple b-values (0-2000 s/mm²) was obtained using a 3.0-T magnetic resonance imaging scanner. The apparent diffusion coefficient was calculated using the mono-exponential model. The distributed diffusion coefficient and intravoxel water molecular diffusion heterogeneity (α) were calculated using the stretched-exponential model. The diffusion coefficient (D), fractional-order derivative in space (β), and spatial parameter (μ) were calculated using the fractional-order calculus model. The liver and tumor specimens of nude mice were immunostained after euthanasia to clarify the liver cancer type. Differences in diffusion-related parameters between the groups were evaluated using Mann-Whitney U-test and univariate logistic analysis. Receiver operating characteristic curves were used to assess the diagnostic efficacy of each parameter. P<0.05 was deemed significant.

Results: α, D, and β were significant discriminators between the groups. The area under the curve for these three variables was 0.890, 0.830, and 0.870, respectively, with cutoff values of 0.491, 0.435, and 0.782, respectively.

Conclusion: The stretched-exponential model parameters α and the fractional-order calculus model parameters D and β showed high diagnostic efficacy in discriminating intrahepatic cholangiocarcinoma from hepatocellular carcinoma in orthotopic xenograft nude mouse models.

Objective: The main objective of this review-type paper is to provide a detailed overview of PCOS along with the current concept of a clinical stance in this complex multigenic disorder.

Method : The following databases were used for literature searches: PubMed, Frontiers, Science Direct, Springer, Wiley, and MDPI. For the purpose of finding pertinent articles and contents, the keywords “PCOS; hirsutism; psychological burden; obesity” and others of a similar nature were utilized.

Conclusion: PCOS is a complicated hormonal, metabolic, and psychological condition with many different clinical manifestations. It is among the most prevalent causes of infertility. Before considering any medication choices, lifestyle modifications should be considered the primary therapeutic prescription for PCOS-related infertility. According to recent studies, PCOS does not affect the risk of ovarian or breast cancer, but it does raise the risk of endometrial cancer in women of all ages. These results suggest that PCOS may increase the risk of gynaecological cancer morbidity. The following stage is ovulation stimulation, which is best accomplished with letrozole and is followed by clomiphene citrate. Women who had not responded to the first-line oral ovulatory medicine were given gonadotropins as a backup. Early detection of girls with a high propensity to develop PCOS will be made possible by a comprehensive knowledge of the condition's etiology. Adolescent PCOS will be better managed overall, related comorbidities will be prevented, and quality of life will increase with customized therapeutic approaches.

Methods: A retrospective observational study was conducted on all children with a haemato-oncology diagnosis or who underwent haematopoietic stem cell transplantation (HSCT) and who were admitted to the Hong Kong Children’s Hospital PICU over a one-year period. Infection characteristics and patient outcomes were evaluated and compared between different sub-groups. Univariable and multi-variable analyses were employed to identify risk factors associated with the development of active infection.

Results: Forty-five (36.3%) of 124 critically ill haemato-oncology admissions to PICU were associated with infections, of which 31 (25%) admissions involved bacterial infections, 26 (20.9%) involved viral infections and 6 (4.8%) involved fungal infections. Bloodstream infection was the most common type of infection. More than half (61.3%) of the bacterial infections were due to an antibiotic-resistant strain. After adjusting for confounding variables, post-HSCT status and neutropenia were significantly associated with active infections.

Conclusion: Infections in critically-ill haemato-oncological patients are associated with post haematopoietic stem cell transplant status and neutropenia. Further study is warranted to review effective strategies that may mitigate the likelihood of infection in this patient population.

Objective: This study aimed to review the possible effects of Per and poly-fluoroalkyl substances exposure and their mechanism in overweight/obese children from pregnant ladies.

Methods: A detailed literature survey was conducted using online databases, including Science Direct, Google Scholar, Scopus, Cochrane, and PubMed. The study focused on the diverse effects of PFAS on maternal and child health, with particular emphasis on neurological complications.

Results: Child growth development depends upon breastfeeding and placenta health, which is disrupted by PFAS exposure, ultimately destroying the body mass index of the child. Neurotoxicity testing utilized the SH-SY5Y human-derived cell line as an in vitro model, revealing PFAS-induced increases in adipocyte number, reduced cell size, altered lipid conglomeration, increased adiposity, and changes in liver function. in vivo studies in mice and human cell lines indicated PPAR-γ and ER-α activation, leading to adiposity and weight gain through Estrogen signaling and Lipid metabolism. PFAS concentrations positively correlated in maternal sera, analyzed by liquid chromatography/quadrupole mass spectrometry.

Conclusion: PFAS, with a long half-life of 3.5-8.5 years, is commonly found in the serum of pregnant women, crossing the placenta barrier. This exposure disrupts placental homeostasis, negatively impacting mechanisms of action and potentially leading to deterioration in pregnancy and child health. Further research is needed to comprehensively understand the complex interplay between PFAS exposure and its implications for maternal and child well-being.

Case Presentation: We have, herein, presented a case with stage IV neuroblastoma who relapsed after 11 years and had a subsequent relapse after 15 years from the initial diagnosis, and reviewed cases with late relapsed (after >5 years) neuroblastoma in the literature. The case presented with recurrent disease at the T7 vertebra after 11 years from the initial diagnosis. The patient received surgery, che motherapy, MIBG treatment, and antiGD2 combined with che motherapy, and had a further local recurrence in the paravertebral area of the re moved T7 vertebra after three years. The patient was operated, received anti-GD2 combined with che motherapy, and is still alive with no symptoms for 19 months after the last relapse.

Conclusion: There is not a well-established treatment regimen for the majority of these patients. MIBG treatment and antiGD2 combined with che motherapy may be promising options for relapsed/ refractory neuroblastoma.

Method: 34 patients in the drug group received 4 capsules of Mastic pill plus Omeprazole capsule 20 mg daily. 34 patients in the placebo group received the same dosing of Omeprazole and placebo. The medication was given to patients for a total duration of 4 weeks. All patients were requested to fill out the modified GERD-HRQL questionnaire at the beginning and every two weeks for a total duration of six weeks.

Result: Reflux, and heartburn severity score as well as disruption of personal life score significantly reduced in both groups, but it was more remarkable in the drug group (P-value = 0.0001). Dysphagia, early satiation, and nausea significantly reduced in the drug group while the placebo group showed no improvement. Our results suggest that constipation, bloating, belching, and odynophagia did not significantly improve in none of the groups.

Conclusion: This study showed that Habb-e-Mastaki is effective against GERD. Further detailed in vitro and in vivo studies aimed at discovering the mechanism of action of this formulation and clinical studies involving a larger population will be necessary to explain and confirm the results obtained in the present study.

Methods: This paper aims to identify current science on how prebiotics, probiotics, and synbiotics can improve gut microbiota dysbiosis.

Results: We reviewed the existing literature related to the role of pre-, pro-, and synbiotics in child health, and the evidence mapping method was chosen as the rapid review to identify gaps in knowledge and future research needs.

Conclusion: In conclusion, the current evidence on the role of prebiotics, probiotics, and synbiotics on child health, while limited, showed promising results on the allergy and immunology pathway, including infection prevention for the gastrointestinal and respiratory tract.

Objectives: The purpose of this research was to see whether an approach involving the development of nanostructured lipid carriers (NLCs) might be used to create an effective, innovative oral formulation of LCH. The efficacy of several synthetic and natural liquid lipids was compared using a hot homogenization-ultrasonication strategy.

Methods: Following initial improvements with hot homogenization and ultrasonication, the LCHloaded NLCs formulation was fine-tuned by Box-Behnken statistical analysis. The optimal LCHNLCs composition includes the lipid phase (2-4% w/v) of stearic acid and oleic acid, the surfactants poloxamer 188 (1%) and Tween 80(1%), and other ingredients.

Results: The optimized NLCs formulation was found to have mean vesicle sizes of 128.72 ± 1.59 nm, polydispersity indices of 0.169 ± 0.06, zeta potentials of -36.81 ± 0.42 mV, and entrapment efficiencies of 79.84 ± 0.11%. The optimized NLCs formulation released much more LCH (88.74 ± 4.62) than the LCH-suspension (36.84 ± 0.37%) in in-vitro drug release experiments lasting up to 24 hours. Ex vivo studies on the ability of LCH-NLCs to pass through the gut showed that drug permeation was much better than it was with plain LCH-solution. The in vivo pharmacodynamic analysis demonstrated that, compared to conventional LCH-suspension, NLCs released LCH more slowly and steadily over a longer time period.

Conclusion: These findings provide additional evidence that NLCs have great promise as a drug delivery technology for the treatment of hypertension, just as they show promise as a controlled release formulation for the treatment of LCH.

Methods: To investigate the role of NNAT, its expression was silenced in NSCLC cell lines A549 and H226. Subsequently, various parameters, including cell proliferation, invasion, migration, and apoptosis, were assessed. Additionally, cell-derived xenograft models were established to evaluate the effect of NNAT knockdown on tumor growth. The expression of key molecules, including cyclin D1, B-cell leukemia/lymphoma 2 (Bcl-2), p65, matrix metalloproteinase (MMP) 2, and nerve growth factor (NGF) were examined both in vitro and in vivo. Nerve fiber density within tumor tissues was analyzed using silver staining.

Results: Upon NNAT knockdown, a remarkable reduction in NSCLC cell proliferation, invasion, and migration was observed, accompanied by elevated levels of apoptosis. Furthermore, the expression of cyclin D1, Bcl-2, MMP2, and phosphorylated p65 (p-p65) showed significant downregulation. In vivo, NNAT knockdown led to substantial inhibition of tumor growth and a concurrent decrease in cyclinD1, Bcl-2, MMP2, and p-p65 expression within tumor tissues. Importantly, NNAT knockdown also led to a decrease in nerve fiber density and downregulation of NGF expression within the xenograft tumor tissues.

Conclusion: Collectively, these findings suggest that neuronatin plays a pivotal role in driving NSCLC progression, potentially through the activation of the nuclear factor-kappa B signaling cascade. Additionally, neuronatin may contribute to the modulation of tumor microenvironment innervation in NSCLC. Targeting neuronatin inhibition emerges as a promising strategy for potential anti-NSCLC therapeutic intervention.

Methods: Twelve quassinoids from E. longifolia and their interactions with DHFR were evaluated via Autodock 4.2 software and Biovia Discovery Studio Visualiser. Their drug-likeness and pharmacokinetic properties were also assessed using the ADMETlab 2.0 program.

Results: The molecular docking results showed that eleven quassinoids showed better docking scores than methotrexate, in which the binding energy (BE) of these quassinoids ranged from - 7.87 to -9.58 kcal/mol. Their inhibition constant (Ki) ranged from 0.095 to 1.71 μM. At the same time, the BE and Ki values for methotrexate were -7.80 kcal/mol and 1.64 μM, respectively.

Conclusion: From the analysis, 6-dehydrolongilactone and eurycomalide B are among the twelve compounds that showed great potential as hit-to-lead compounds based on the docking score on DHFR, drug-likeness, and ADMET properties. These results suggest a great potential to pursue validation studies via in vitro and in vivo models.

Objective: By preparing cefdinir's spanlastic nanovesicles (SNVs) using the ethanol injection method, the current study has attempted to enhance the drug's solubility and bioavailability using a statistical design approach.

Methods: Independent variables, including the nonionic surfactant concentration, edge activator (EA), sonication time, SNVs entrapment efficiency, particle size, zeta potential, PDI, and in vitro release, have been evaluated. The best CFD-SNVs were positioned within in situ gel with mucoadhesive properties made of hydroxypropyl methylcellulose and deacetylated gellan gum. By contrasting intranasal injection of the produced gel with an IV solution, animal models have been used to investigate CFD's systemic and cerebral dynamics.

Results: Statistical analysis has suggested an ideal SNVs formulation with nonionic surfactant (65 mg), EA (15 mg), and sonication (3 min). The sol-gel temperature for forming the mucoadhesive in situ gel containing SNVs has been found to be 34.03°C, and 18.36 minutes has been the extended mucociliary transit time. Following intranasal injection, compared to SNV dispersion, the gelling system has exhibited higher brain bioavailability (2251.9 ± 75 vs. 5281.6 ± 51%, respectively). The gel has also demonstrated effective drug targeting of the brain with higher direct transport percentage indices.

Conclusion: Mucoadhesive in situ gel with CFD-loaded SNVs can be administered via the intranasal route. To enhance bioavailability in the brain and drug targeting from the nose to the brain, nasal in situ gel loaded with CFD-SNVs could be a new carrier to be employed in sinusitis.

Method: This Delphi study was conducted in three rounds from September to November 2019. A purposively selected 17 national experts, including obstetricians, reproductive health professionals, and midwives, participated in this study.

Results: Most of the 52 initial strategies in the first round (50 strategies) were approved with a few corrections in the first and second rounds, and 23 strategies were presented in the third-round questionnaire; most panelists agreed upon them. Finally, they approved 73 strategies with five categories: promoting professional support, enhancing control skills, encouraging empowerment, promoting spouse and other important support, and improving childbirth preparation.

Conclusion: The Delphi approach allows for developing a consensus that will serve as a template for education, practice, and future research in maternity care units. Hence, multidimensional approaches are required to promote positive childbirth experiences that can potentially improve mothers’ well-being outcomes.

Objectives: The objective of this review was to relate the consumption of probiotic bacteria and its effects on inflammatory diseases, including obesity, type II diabetes and celiac disease.

Methods: A search was carried out in English, between the years 2011 and 2022, for research articles and clinical trials with humans and in vivo studies. Research showed improvement in cardiovascular risk markers, and improvement in insulin sensitivity, lipid profile and plasma atherogenic index, in obesity with the use of probiotics. In type II diabetes, decreased levels of fasting glucose, glycated hemoglobin, insulin and glycemic index, and increased levels of peptide 1, superoxide dismutase and glutathione peroxidase were observed.

Results: In addition to cellular protection of the islets of Langerhans and positive alteration of TNF- α and IL-1β markers. Improvement in the condition of patients with celiac disease was observed, since the neutralization of the imbalance in serotonin levels was observed, reducing the expression of genes of interest and also, a decrease in cytokines.

Conclusion: Therefore, the use of probiotics should be encouraged.

Methods: The prepared library of compounds underwent comprehensive assessment for their biological activities, encompassing antioxidative, antiproliferative, and antibacterial properties, in addition to in vivo toxicity evaluation using a Zebrafish model. Compound 4i, which consists of a retinoic acid moiety, exhibited the strongest scavenging activity against ABTS radicals (IC₅₀ = 36 ± 2 μM). In addition, 4b and some of the analogues (4a, 4c and 4i), mostly containing an unsaturated chain and conjugated double bonds, showed moderate but non-selective activity with certain IC₅₀ values in the range of 20-40 μM.

Results: In contrast, the analogue 4l, a derivative of alpha-linolenic acid, was the least toxic towards normal cell lines. Moreover, 4b was also highly active against Gram-positive Bacillus subtilis with an MIC of 125 μM. Nevertheless, both 4b and 4i, known for the best-observed effects, caused remarkable developmental abnormalities in the zebrafish model Danio rerio.

Conclusion: Since modification of the side chain did not significantly alter the change in biological activities compared to the parent compound, granulatamide B (4b), the substitution of the indole ring needs to be considered. Our group is currently carrying out new syntheses focusing on the functionalization of the indole core.
