Objectives: Despite advancements in biological therapies, significant clinical needs persist. This review aims to discuss novel treatments, guiding future guidelines and drug discoveries for rheumatoid arthritis.

Methods: This review follows the 2020 PRISMA statement, utilising PubMed and Google Scholar for literature search and emphasizing recent meta-analyses on the safety and efficacy of targeted immunobiological medications.

Results: Small molecule inhibitors, whether utilised independently or in conjunction with Methotrexate, have been shown to contribute to effective disease management and have the potential for better adherence to the American College of Rheumatology criteria. Tocilizumab therapy demonstrates a significant reduction in disease activity and improves rates of disease remission when combined with Methotrexate. Investigations of mesenchymal stromal cell therapies have had promising outcomes, improving both cartilage quality (as evaluated by Macroscopic Cartilage Repair Assessment) and joint tenderness and swelling in clinical joint counts. Intra-articular administration of tolerogenic dendritic cells has displayed a capacity to alleviate pain, as measured by Visual Analog Scale scores, and enhance the Disease Activity Score across 28 joints. Resveratrol capsules supplemented with allopathic therapy show potential in reducing TNF-α and interleukin-6 serum levels.

Conclusion: More investigations and their analysis will improve patient outcomes and reduce adverse effects and the costs involved in developing and obtaining immunobiological drugs. Moreover, assessing the safety and efficacy of anti-RA properties of the bioactive compounds could offer less toxic and more cost-effective natural treatment options.

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.

Objectives: The shortcomings of various conventional treatments have prompted urgent efforts to discover safe, natural compounds that may be useful in combating COVID-19. This study aims to review research that has investigated the potential of traditional phytotherapies used by different populations for the prevention and symptomatic treatment of COVID-19 infection.

Methods: This paper reviewed scientific studies published through searching on search engines such as PubMed, Scopus, Google Scholar, ScienceDirect and Elsevier from May until October 2023.

Results: The preventive and anti-COVID-19 attributes of Traditional Chinese Medicine, Ayurvedic formulations and African medicinal plants have been substantiated in research. In Nepal, recommendations endorse the utilisation of medicinal plants for herbal teas and homemade sanitizers. Zingiber officinale, Curcuma longa L. and Curcuma xanthorriza Roxb., along with Camellia sinensis are crucial Indonesian medicinal plants with potential for treating COVID-19. Z. officinale was predominantly chosen for relieving coughs and sore throats associated with COVID-19 in Saudi Arabia.

Discussion: The immunomodulatory properties of medicinal plants, which may prove useful in combating COVID-19, have been verified via elevation of the level of peripheral WBCs, IgM, IgG; inhibition of leukotrienes and prostaglandins, maintenance of the integrity of intestinal mucosal barrier and regulation of HMGB1. The antiviral effects of herbs, including the inhibition of viral DNA and RNA replication, down-regulation of oxidative stress, and the impediment of SARS-CoV-2 access to vascular endothelial cells, suggest their potential to facilitate earlier recovery from COVID-19 infection.

Conclusion: Advancing scientific research in phytotherapy promises the possibility of novel approaches for effectively managing future infectious diseases and pandemics.

Objective: In this comprehensive review, we have elaborated on the pathophysiology, and various signaling pathways linked with Sarcopenia. Also, discussed the preclinical models and current interventional therapeutics to treat muscle wasting in older patients.

Conclusion: In a nutshell, a comprehensive description of the pathophysiology, mechanisms, animal models, and interventions of Sarcopenia. We also shed light on pharmacotherapeutics present in clinical trials which are being developed as potential therapeutic options for wasting diseases. Thus, this review could fill in the knowledge gaps regarding Sarcopenia-related muscle loss and muscle quality for both researchers and clinicians.

Objective: This paper aims to discuss the mechanism of actions, pathways, and metabolites triggered due to the development of neuropathy and nephropathy post-long-haul diabetes in patients. The therapeutic targets are also highlighted, proving to be a potential cure for such conditions.

Methods: Research works were searched from international and national databases with keywords like “diabetes,” “diabetic nephropathy,” “NADPH,” “oxidative stress,” “PKC,” “Molecular mechanisms,” “ cellular mechanisms,” “complications of diabetes,” and “factors.” The databases searched were PubMed, Scopus, Directory of open access journals, Semantic Scholar, Core, Europe PMC, EMBASE, Nutrition, FSTA- Food Science and Technology, Merck Index, Google Scholar, PubMed, Science Open, MedlinePlus, Indian citation index, World Wide Science, and Shodhganga.

Results: Pathways causing protein kinase C (PKC) activation, free radical injury, oxidative stress, and aggravating the conditions of neuropathy and nephropathy were discussed. In diabetic neuropathy and nephropathy, neurons and nephrons are affected to the extent that their normal physiology is disturbed, thus leading to further complications and conditions of loss of nerve sensation in diabetic neuropathy and kidney failure in diabetic nephropathy.

Current treatment options available for the management of diabetic neuropathy are anticonvulsants, antidepressants, and topical medications, including capsaicin. According to AAN guidelines, pregabalin is recommended as the first line of therapy, whereas other drugs currently used for treatment are gabapentin, venlafaxine, opioids, amitriptyline, and valproate.

Drug targets for treating diabetic neuropathy must suppress the activated polyol pathways, kinase C, hexosamine, and other pathways, which amplify neuroinflammation. Targeted therapy must focus on the reduction of oxidative stress and proinflammatory cytokines and suppression of neuroinflammation, NF-κB, AP-1, etc.

Conclusion: Potential drug targets must be considered for new research on the treatment of neuropathy and nephropathy conditions.]]> https://www.benthamscience.comarticle/138153 https://www.benthamscience.comarticle/135496 https://www.benthamscience.comarticle/138046 https://www.benthamscience.comarticle/133810 https://www.benthamscience.comarticle/135222Objective: The potential mechanism underlying the protective effect of Astragaloside IV (AS-IV) co-treatment with 1, 25-dihydroxy-vitamin D (Vit-D) on neuropathy in diabetic high-fat rats was investigated.

Methods: The rat diabetic hyperlipidemia (DH) model was established via streptozotocin and a high-fat diet (HFD). After co-treatment (of AS-IV and Vit-D at respective doses of 50 mg/kg via oral gavage and 30000 IU/kg via intramuscular injection), blood glucose levels, markers of inflammation and oxidative stress, as well as apoptosis and histopathology were evaluated with appropriate techniques.

Results: Co-treatment could effectively reduce blood glucose levels substantially (p< 0.01), improve weight loss, and decrease oral glucose tolerance. Reduced respective sensory and motor nerve conduction velocities in rats were substantially improved (p<0.01) after co-treatment. Also, we observed obvious improvement in DH-induced injured nerve fiber myelin structure and other organ pathologies in co-treated rats. Besides, we observed up-regulated expressions of peroxisomal-proliferator activated receptor-alpha (PPAR-α) and Vit-D receptors (VDR) (p< 0.01) through the western blotting technique. Using the same technique, we also discovered reduced levels of interleukin (IL)1 beta, IL-6, and tumor necrosis factor-alpha, coupled with increased IL-10 and superoxide dismutase levels (p< 0.01). Importantly, co-treatment could effectively exert antioxidative and anti-inflammatory effects. Also, co-treatment resulted in the up-regulation of PPAR-α and VDR expressions, inhibition of the renin–angiotensin–aldosterone system, and promotion of β-cell sensitivity to insulin.

Conclusion: The combined application of AS-IV and Vit-D exhibited health effects such as anti-oxidation, regulation of inflammatory factors, and promotion of cell repair, which may be considered as the mechanisms underlying treatment of diabetic peripheral neuropathy and improvement in biochemical indicators.

Aims: Considering this fact, the present study reviewed the impact of arsenic on amyloid precursor protein, which is known to cause one of the commonest cognitive disorders such as Alzheimer’s disease.

Methods: The present study reviews the arsenic role in the generation of amyloid-beta from its precursor that leads to Alzheimer’s disease through the published article from Pubmed and Scopus.

Description: According to the findings, regular, long-term exposure to arsenic beginning in infancy changes numerous arsenic level-regulating regions in the rat brain, which are related to cognitive impairments. Arsenic also affects the BBB clearance route by increasing RAGE expression. Arsenic triggers the proamyloidogenic pathway by increasing APP expression and subsequently, its processing by β-secretase and presenilin. Arsenic also affects mitochondrial dynamics, DNA repair pathway and epigenetic changes. The mechanism behind all these changes is explained in the present review article.

Conclusion: A raised level of arsenic exposure affects the amyloid precursor protein, a factor for the early precipitation of Alzheimer’s disease.

Objective: This study examined the expression profile of FGFR3 in human synovial biopsy tissues and evaluated its gene-silencing effects on behaviors of synovial cells.

Methods: Immunohistochemical staining was used to measure FGFR3 expression in human RA joint tissues. Cell proliferation, migration, and apoptosis assays were used to monitor behavioral changes in cultured synovial SW-982 cells with siRNA-mediated FGFR3 gene silencing. Immunofluorescent staining and western blotting were used to detect molecular changes in the FGFR3 gene-silenced cells.

Results: FGFR3 up-regulation was noted in both cytoplasms and nuclei of synovial cells in human RA joints. FGFR3 siRNA delivery experiments corroborated that FGFR3 knockdown decreased proliferation and migration, and triggered apoptosis of synovial cells. The FGFR3 gene knockdown enhanced constitutive expression of epithelial marker E-cadherin and conversely suppressed expression of epithelial-mesenchymal transition (EMT) markers, including Snail, fibronectin, and vimentin. In addition, FGFR3 silencing significantly reduced the constitutive expressions of TNF-α, transcription factor NF-κΒ, and downstream COX-2 protein and collagenolytic enzyme MMP-9. MAPK inhibition markedly suppressed constitutive levels of NF-κΒ, COX-2, and MMP-9.

Conclusion: Genetic interference of FGFR3 could modulate the expression of inflammatory mediators and EMT markers in the synovial cells. Targeting the FGFR3/MAPK signal axis may be considered a useful therapeutic strategy to ameliorate the development of RA.

Background: GBM is the most malignant primary brain cancer with a poor prognosis. Previous studies have suggested that GBM vessels undergo dynamic remodeling modulated by tumor vasodilation and vasoconstriction instead of tumor angiogenesis.

Objective: Here, we have first investigated the expression and function of UTS2, a potent vasoconstrictor, in GBM.

Methods: The mRNA expression profiles and clinical information of GBM patients were obtained from the TCGA database. The clinical relevance of UTS2 was explored by the Mann-Whitney U test and Cox hazard regression survival test. We further explored the role of UTS2 in GBM cell proliferation, migration, and tumor immune microenvironment. Moreover, we established the in vivo mice model to validate its oncogenic effects on GBM progression.

Results: Although we did not find significant correlations between UTS2 expression and patients’ clinical characteristics, UTS2 was identified as a valid independent prognostic indicator according to multivariate survival analysis. Knockdown of UTS2 resulted in decreased GBM cell proliferation and migration. In addition, functional enrichment analysis implied UTS2 to be involved in the regulation of the immune microenvironment. In vivo studies showed that UTS2 knockdown suppressed GBM xenograft growth, highlighting the tumor-promoting effects of UTS2 on GBM.

Conclusion: Our study identified that UTS2 could predict the prognosis of GBM patients and provided evidence regarding its oncogenic effects both in vitro and in vivo.

Case Presentation: A fifty-five-year-old woman with a known history of type 2 diabetes mellitus was referred to our clinic with blurred vision. After detailed anamnesis and clinical assessment, she was diagnosed as primary ITP in haematology department, and systemic steroid (1.5mg/kg) therapy was initiated. During her follow-up, a concomitant peripheral facial paralysis (PFP) emerged. In the course of follow-up, her platelet counts increased gradually, the retinal haemorrhages regressed partially, and the PFP recovered completely.

Conclusion: ITP is a rare haematologic disease that sometimes manifests with additional systemic involvements, and this disease should be remembered in the differential diagnosis of unusual retinal haemorrhages, which might be the only presenting feature.

Methods: A total of 193 patients (mean age: 58 ± 12 years) with suspected coronary heart disease indicated for CCTA between May and October 2022 were prospectively enrolled. The subjects were divided into five groups according to body weight: < 60 kg, 60 – 69 kg, 70 – 79 kg, 80 – 89 kg, and ≥ 90 kg. The tube voltage and IDR settings of each group were as follows: 70 kVp/0.8 gI/s, 80 kVp/1.0 gI/s, 80 kVp/1.1 gI/s, 100 kVp/1.5 gI/s, and 100 kVp/1.5 gI/s, respectively. Objective image quality data included the CT value and standard deviation (noise) of the aortic root (AR), the proximal left anterior descending branch (LAD), and the distal right coronary artery (RCA), as well as the signal-to-noise ratio and contrast-to-noise ratio of the LAD and RCA. Subjective image quality assessment was performed based on the 18-segment model. Contrast and radiation doses, as well as effective dose (ED), were recorded. All continuous variables were compared using either the one-way ANOVA or the Kruskal-Wallis rank sum test.

Results: No significant differences were observed in all objective and subjective parameters of image quality between the groups (P > 0.05). However, significant differences in contrast and radiation doses were observed (P < 0.05). The contrast doses across the weight groups were 27 mL, 35 mL, 38 mL, 53 mL, and 53 mL, respectively, while the ED were 1.567 (1.30, 2.197) mSv, 1.53 (1.373, 1.78) mSv, 2.113 (1.963, 2.256) mSv, 4.22 (3.771, 4.483) mSv, and 4.786 (4.339, 5.536) mSv, respectively.

Conclusion: Weight-based tube voltage and IDR yielded consistently high image quality, and allowed for further reduction in contrast and radiation exposure during CCTA for coronary artery diseases.

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.

Case Presentation A 49-year-old man presented with hemiparesis. Preoperative neuroimaging revealed a giant lesion and an AVM on the left hemisphere of the brain. Craniotomy and tumour resection were performed. The AVM was not treated and needed to be followed up. The histological diagnosis was meningioma (World Health Organization grade I). The patient was in good neurological condition postoperatively.

Conclusion This case adds to the growing literature suggesting that the association between the two lesions is complex. Besides, treatment depends on the risk of neurologic function damage and hemorrhagic stroke of meningiomas and AVMs.

Materials and Methods: Patients who were admitted to the emergency department with abdominal pain were recruited retrospectively from the hospital information system. Grouping was carried out on the basis of AMI (n=78) and non-AMI (n=78). In both groups, the corrected QT (QTc) and QT dispersion (QTD) were measured on electrocardiographs, and the qualitative and quantitative CT findings were evaluated on CT examinations.

Results: The QTc and QTD values were higher in the AMI group. The median QTc values were 456.16 (IQR: 422.88-483.16) for the AMI group and 388.83 (IQR: 359.74-415.83) for the control group (p<0.001), and the median QTD values were 58 (IQR: 50.3-68.25) for the AMI group and 46 (IQR: 42-50) for the control group (p<0.001).

In the CT analysis, the QTc values were significantly higher among AMI patients, with images of paper-thin bowel walls and the absence of bowel wall enhancement (p=0.042 and p=0.042, respectively). Meanwhile, the QTD values were significantly higher among patients with venous pneumatosis findings on CT (p=0.005). In the regression analysis, a significant relationship was found between the QT parameters and AMI (p<0.001). For QTc, an AUC of 0.903 (95% CI: 0.857-0.950, p<0.001), a sensitivity of 80.8%, and a specificity of 82.3% were found. For QTD, an AUC of 0.821 (95% CI: 0.753-0.889, p<0.001), a sensitivity of 73.1%, and a specificity of 82.3% were found.

Conclusion: We found the QTc and QTD values to be significantly higher among AMI patients. Furthermore, we found a significant relationship between the CT findings and QTc and QTD and a significant relationship between survival and QTc in the AMI group.

Case Presentation: We report a 53-year-old female patient with sigmoid colon cancer and perforation who underwent a surgical operation. Three years after the operation, reexamination of the liver through computed tomography and magnetic resonance imagery scanning revealed multiple progressive liver lesions. However, the liver biopsy did not show malignant changes. Repeated analysis of the patient's liver magnetic resonance imaging revealed that multiple liver nodules were significantly enhanced in the arterial phase and that the portal vein density/signal ratio was higher than that of the liver parenchyma. The coincidence of doughnut-shaped nodules and high signal in the hepatobiliary phase, combined with the results of pathological liver puncture examination, led to nodular regenerative hyperplasia being considered as a possible diagnosis.

Conclusion: A review of the relevant literature showed that following oxaliplatin chemotherapy for colorectal cancer, it is not uncommon for doughnut-shaped nodules with obvious enhancement in the middle hepatic artery phase and high signal intensity in the hepatobiliary phase to develop. Such changes should be paid sufficient attention by radiologists.

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.

Case Reports: Three hospitalised patients aged 23 to 86 years underwent venous air embolism (VAE) in the right heart system after performing CTPA. One of the patients died from a complication of venous thromboembolic disease (PE, coronary sinus thrombosis, mesenteric venous thrombosis).

Conclusion: CTPA is a procedure that a priori seems innocuous, but it can be a potential cause of death or serious consequences for patients undergoing radiological procedures where the administration of contrast and the use of an injector could be counterproductive. Radiologists and physicians responsible for the patient should be aware of vascular gas embolism after contrast injection in patients undergoing CTPA.

Background: The heat sink effect is an important factor affecting the therapeutic effect of tumor thermal ablation. At present, there is no algorithm model to predict the intraoperative heat sink effect automatically, which needs to be measured manually, which lacks accuracy and consumes time.

Objective: To construct a segmentation model based on a convolutional neural network that can automatically identify and segment pulmonary nodules and vascular structure and measure the distance between the nodule and vascular.

Methods: First, the classical Faster RCNN model was used as the nodule detection network. After obtaining the bounding box of pulmonary nodules, the VSPP-NET model was used to segment nodules in the bounding box. The distance from the nodule to the vasculature was measured after the surrounding vasculature was segmented by the VSPP-NET model. The lung CT images of 392 patients with pulmonary nodules were used as the training data for the algorithm. 68 cases were used as algorithm validation data, 29 as nodule algorithm test data, and 80 as vascular algorithm test data. We compared the heat sink effect of 29 cases of data with the results of the algorithm model and expert segmentation and compared the difference between the two results.

Results: In pulmonary CT image vasculature segmentation, the recall and precision of the algorithm model reached >0.88 and >0.78, respectively. The average time for automatic segmentation of each image model is 29 seconds, and the average time for manual segmentation is 158 seconds. The output image of the model shows that the results of nodule segmentation and nodule distance measurement are satisfactory. In terms of heat sink effect prediction, the positive rate of the algorithm group was 28.3%, and that of the expert group was 32.1%, with no significant difference between the two groups (p=0.687).

Conclusion: The algorithm model developed in this study shows good performance in predicting the heat sink effect during pulmonary thermal ablation. It can improve the speed and accuracy of nodule and vessel segmentation, save ablation planning time, reduce the interference of human factors, and provide more reference information for surgeons to make ablation plans to improve the ablation effect.

Case Presentation: A 59-year-old man was hospitalized with acute pain in the left upper extremity. Ultrasound revealed segmental swelling of multiple nerves around his left elbow with abundant blood flow signals. Contrast-Enhanced Ultrasound (CEUS) showed a rapid, complete and homogenous enhancement in the nerve lesions in the early arterial phase. The NL was confirmed by imaging and flow cytometry, and he accepted chemotherapy. The posttherapeutic ultrasound showed that the nerves in the left upper limb were basically normal. Unfortunately, the patient died of cerebral metastasis in 5 months.

Conclusion: The nerve US and CEUS can show specific manifestations and provide more diagnostic information about NL.

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.

Background: Complex regional pain syndrome (CRPS) type I is also known as shoulder hand syndrome (SHS). Its main symptoms include shoulder pain, limited activity, upper arm, wrist, and knuckle joint pain. Ultrasonic elastic imaging technology is gradually being applied to musculoskeletal system evaluation, primarily for the elastic examination of superficial tissue, as a result of the continual advancements in ultrasound technology. To make up for the absence of conventional imaging, functional state evaluation of the motor system can offer conventional ultrasonic tissue elasticity and hardness data.

Objectives: The purpose of this study was to objectively quantify the soft tissue surrounding the shoulder joint of stroke patients with CRPS using ultrasonic elastic imaging and to determine the diagnostic usefulness of ultrasonic elastic imaging for CRPS in stroke in order to promote its usage in clinical practice.

Materials and Methods: Patients diagnosed with CRPS following a stroke and admitted to the rehabilitation unit at Shanxi Bethune Hospital between January, 2021 to June, 2021 were included in the analysis. The control group consisted of people without pain in their shoulder joints. Each group consisted of 30 patients. A high-frequency wire array probe (frequency = 8-16 Hz) was employed in conjunction with an ultrasonic diagnostic apparatus. A quantitative analytic system determined Young's modulus of the tissue, while the tracking of the shear wave provided an elastin map in real-time. An excitation pulse of acoustic radiation force was used to cause shear waves in the tissue.

Results: The Young's modulus of supraspinatus muscle in the study and control groups was 289.16±22.07 Kpa and 231.99±23.61 Kpa, respectively (P <0.01). Young's modulus values of the study group's subscapular biceps were compared to those of the control group (P > 0.05). The supraspinatus shear wave elastographic (SWE) imaging value was 10.01±0.49 m/s in the study group and 7.92±0.50 in the control group (P <0.05). The study and control groups had subscapular muscle SWE values of 15.99±1.95 and 8.64±0.56 m/s, respectively (P <0.05). The average biceps tendon SWE value in the study and control groups was 6.39±0.42 and 4.69±0.36 m/s, respectively (P <0.05).

Conclusion: In conclusion, the SWE assessed by ultrasound elastography is useful for early diagnosis and evaluation of the superior shoulder tendon, subscapular tendon, and biceps tendon of CRPS following stroke.]]> https://www.benthamscience.comarticle/134204Background: The jaws can be affected by several lesions that manifest in the oral cavity, but little is known about non-odontogenic benign and malignant lesions and their radiological findings.

Introduction: Our aim was to discuss the imaging findings of non-odontogenic jaw lesions to help the surgeon in the diagnosis and formulating a differential diagnosis for this vast spectrum of jaw lesions with overlapping clinical and imaging appearances.

Methods: CT and MR images of the mandible, maxillofacial region, and neck were retrieved from the archive of the Radiology Department of Pamukkale University for the duration between 2012-2023 and assessed.

Results: A total of 8125 CT and MR images were retrospectively analyzed. The mean age of the patients was 39.5 years in females and 43.2 in males, with a range varying from 15 to 72 years. Histopathologically approved benign and malignant non-odontogenic lesions were detected in only 19 patients out of 8125 images (0.23%). Osteomyelitis and abscess were the most common (n=3; 0.03%), followed by two cases (n=2; 0.02%) of each fibrous dysplasia, hemangioma, osteosarcoma, squamous cell carcinoma, and multiple myeloma, and one case (n=1; 0.01%) of each ossifying fibroma, osteoma, lymphoma, metastasis, and solitary bone cyst.

Conclusion: Although non-odontogenic benign and malignant lesions of the jaw are rare, awareness of the radiological features of these lesions plays an important role in their diagnosis and management.

Case Presentation: We report a 28-year-old man who was diagnosed 20 years ago with Klippel-Trenaunay syndrome. Approximately 3 years ago, he found enlarged masses on both upper extremities and a new dark red mass that was pathologically diagnosed as cavernous haemangioma appeared on the right index finger.

Conclusion: KTS is a rare and potentially multisystem disease requiring multidisciplinary management for which imaging examination is an important auxiliary diagnostic method. Various complications may occur during its development, so regular follow-up is required to prevent serious accidents.

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.

Case Presentation: An induration with mild discomfort was detected in the upper inner quadrant of the right breast of a 27-year-old Chinese woman with regular menstrual cycles. The patient is currently unmarried and has no previous history of full-term pregnancies or lactation. An ill-defined, subcutaneous, hyperechoic lesion with no calcification was visualized on breast ultrasound. Peripheral and internal blood flow signals demonstrated high intensity. Pathological analysis of a breast needle biopsy revealed fat lobule necrosis accompanied by mixed lymphoplasmacytic and histiocytic aggregates.

Conclusion: The diagnosis of lupus mastitis necessitates a comprehensive evaluation of the patient's medical history, serological testing, imaging studies, and histopathological analysis.

Objective: This study aimed to analyze the difference in the FAI ratio between pericoronary adipose tissue volume and aortic root epicardial adipose tissue volume (AO-EATV) using computed tomography (CT) in various plaques.

Methods: In total, 645 coronary artery CT angiogram images from 215 patients were collected. The types and number of coronary plaques were recorded, and the plaque volume and pericoronary FAI of each branch were compared between the groups. The ratio of the FAI in branches with or without plaques to the AO-EATV was determined and statistically analyzed between the groups.

Results: No significant difference in the plaque volume among the left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA) (P > 0.05) as well as in the FAI was observed among various plaque groups (P > 0.05). FAI[LAD]/AO-EATV was in the following order: noncalcified plaques (0.70 ± 0.06) < mixed plaques (0.72 ± 0.06) < calcified plaques (0.73 ± 0.08) < no plaques (0.74 ± 0.07); FAI[LCX]/AOEATV was in the following order: noncalcified plaques (0.71 ± 0.06) < mixed plaques (0.72 ± 0.08) < calcified plaques (0.73 ± 0.09) < no plaques (0.74 ± 0.06); and FAI[RCA]/AO-EATV was in the following order: noncalcified plaques (0.71 ± 0.06) < mixed plaques (0.73 ± 0.07) < calcified plaques (0.74 ± 0.07) < no plaques (0.75 ± 0.09); the differences were statistically significant in each group (P = 0.041, 0.043, and 0.028, respectively).

Conclusion: Compared to simply comparing FAI, FAI/AO-EATV varied in the coronary arteries in various plaque groups. FAI/AO-EATV was lower in noncalcified or mixed plaques and was associated with coronary inflammatory reactions.]]> https://www.benthamscience.comarticle/132211 https://www.benthamscience.comarticle/136600 https://www.benthamscience.comarticle/133462Introduction: A large jejunal diverticulum has been reported as a possible cause of volvulus and acute mesenteric ischemia (AMI) in adults. A large diverticulum of the small bowel complicated with volvulus has been reported before in literature. However, imaging findings of a large diverticulum of the small bowel complicated with both volvulus and AMI on MDCT are rarely described and reported. In this study, we reported a case with a large diverticulum, volvulus, and AMI concurrently; these three imaging findings were reviewed and described on MDCT, and the relevant literature was briefly introduced.

Case Report: We reported the case of a 69-year-old man who presented to our hospital with acute abdominal pain and vomiting. An emergent abdominal enhanced MDCT imaging was performed and demonstrated the volvulus secondary to a large diverticulum of the jejunum complicated with AMI. Here, a case was presented that highlighted unique imaging findings on MDCT, as well as a literature review.

Conclusion: A review of the literature revealed that a single jejunal diverticulum causing both volvulus and AMI is rare in adults. To our knowledge, a systemic description of their signs on MDCT in a case has not been reported yet.

Objective: This study aims to investigate the role of GS in the neovascularization of gliomas through the utilization of MR vessel-size imaging and histopathological techniques.

Methods: In this exploratory animal study, we randomly divided the C6 glioma rat models into a control group and an L-methionine sulfoximine (MSO) treatment group. Daily intraperitoneal injections were administered for three consecutive days, starting from day 10 following the implantation of C6 glioma cells in rats. Subsequently, MR vessel size imaging was conducted using a BRUKER 7 T/200 mm MRI scanner, and the MRI results were validated through histopathological examination.

Results: A significant decrease in microvessel density was observed in both the tumor periphery and center areas in the MSO treatment group compared to that in the control group. The mean vessel diameter (mVD) and vessel size index (VSI) did not exhibit significant changes compared to the control group. Moreover, the staining intensity of platelet endothelial cell adhesion molecule-1 (CD31) and GS in the tumor periphery was significantly decreased in the MSO treatment group. Additionally, the MSO treatment demonstrated a substantial inhibition of tumor growth.

Conclusion: GS inhibitors significantly reduced angiogenesis in the periphery area of C6 glioma, exerting an inhibitory effect on tumor progression. Thus, GS inhibitors could be potential therapeutic agents for treating glioma. Additionally, in vivo MR vessel size imaging detects changes in vascularrelated parameters after tumor treatment, making it a promising method for detecting neovascularization in glioma.

Case Presentation: We report a case of a 63-year-old female who presented with abdominal pain. Abdominal CT Angio and dynamic contrast-enhanced abdominal MRI revealed a mass lesion showing markedly contrast enhancement, no vascular invasion sign, and diffusion restriction lesion in the truncus coelicus bifurcation region. The mass was surgically resected completely. Pathological evaluation showed a hyaline-vascular type of Castleman’s disease.

Conclusion: Castleman's disease should be kept in mind in the differential diagnosis of an isolated intra-abdominal mass.

Case Report: A 24-year-old male patient applied to the general surgery department with the complaint of long-standing abdominal pain, nausea and vomiting after meals, and 8-10 kg weight loss in 1 month. Three-phase dynamic abdominopelvic CT showed that the 1st and the 2nd segments of the duodenum were dilated. At this level, a peripherally intensely contrasted heterogeneous mass lesion, 91x70x46 mm in size, was observed. There was oral contrast and air values in the center of the mass. A fistulized mass connected with the duodenal wall was considered in the differential diagnosis. In the surgical exploration, a soft, vascularized mass fistulized to the 2nd segment of the duodenum was observed. Pathological diagnosis was reported as GIST.

Conclusion: GISTs arise from the precursors of Cajal Interstitial cells of the gastrointestinal tract. Contrast-enhanced CT is the preferred diagnostic method for staging, risk stratification, and follow-up. We presented a young case with a giant duodenal GIST and discussed differential diagnosis and some diagnostic properties.

Methods: This study involved 51 fetal specimens. Post-mortem MRI scanning was implemented with a 3.0-T MRI system. T2-weighted imaging (T2WI) features of the thymus in fetuses were quantitatively investigated with DICOM images. Statistical analysis was done with the Chi-Square test, oneway ANOVA, and Student’s t-test.

Results: There was heterogeneity in the morphology of the fetal thymus. FS T2-weighted TSE sequence clearly exhibited the microstructure of the fetal thymus. The thymus extensively showed a lobulated appearance. The central signal is much higher than the peripheral signal in each lobule. In addition, FS-T2WI images can clearly show the interlobular septum, which is filled with fluid and presents a linear high signal. The signal intensity of fetal thymus increased with gestational weeks. The diameter measured in a particular plane was highly correlated with gestational week.

Conclusion: FS T2-weighted TSE sequence provides high-resolution images of the fetal thymus. The change in signal intensity, location, and two-dimensional diameter in a specific plane can be used as a research direction for the fetal thymus.

Objective: This study aimed to compare the duration of the hepatic artery catheterization, fluoroscopy time (FT), radiation exposure, safety, and quality of life associated with the procedure in patients undergoing HAIC via TRA and TFA.

Methods: This prospective, single-center, randomized, controlled study included 120 patients with unresectable HCC undergoing HAIC procedures. Patients were randomly assigned to group A (n = 60, TRA-HAIC) or group B (n = 60, TFA-HAIC). The hepatic artery catheterization time, FT, entrance surface dose (ESD), dose area product (DAP), procedure-related complications, and quality of life associated with the procedure were assessed between the two groups. Independent-sample t-test and analysis of variance (ANOVA) were used to assess differences. Statistical significance was set at P < 0.05.

Results: HAIC procedures were successfully performed in both groups. The hepatic artery catheterization time (19.35 ± 5.84 vs. 18.93 ± 5.62 minutes, P = 0.837), FT (2.35 ± 2.23 vs. 2.25 ± 2.16 minutes, P = 0.901), ESD (259.32 ± 167.46 vs. 250.56 ± 170.58 mGy, P = 0.449), and DAP (125.37 ± 60.65 vs. 120.56 ± 64.33 Gy.cm3, P = 0.566) were comparable between the two groups. The incidence of artery occlusion (10.0% vs. 0%, P < 0.001) in the TRA group was significantly higher than that in the TFA group. TRA was associated with a statistically significant (P < 0.05) improvement in the quality of life.

Conclusion: TRA to HAIC was associated with greater improvement in the quality of life associated with the procedure compared with TFA. Both approaches to HAIC had similar efficiency, safety, radiation exposure, and procedure duration.

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.

Objectives: This study aimed to investigate ocular blood flow in eyes with or without diabetic macular edema using arterial spin labeling.

Methods: This cross-sectional study included 118 eyes of 65 patients with diabetic retinopathy analyzed between November 2018 and December 2019. We included a total of 53 eyes without diabetic macular edema (mean [SD] age, 57.83 [7.23] years; 29 men [54.7%]) and 65 eyes with diabetic macular edema (mean [SD] age, 60.11 [7.63] years; 38 men [58.5%]). Using a 3.0-T magnetic resonance imaging, participants were imaged with arterial spin labeling with multiple post-labeling delays.

Results: The mean ocular blood flow at post-labeling delays of 1.5 and 2.5 s was significantly lower in eyes with diabetic macular edema among patients with diabetic retinopathy compared with the remaining subgroups (P=0.022 and P <0.001, respectively). The mean ocular blood flow exhibited a significant decrease in eyes with diabetic macular edema when the post-labeling delay was set at 2.5 s in the nonproliferative and proliferative diabetic retinopathy groups, compared with the remaining subgroups (P=0.005 and P=0.002, respectively). The cutoff points of ocular blood flow at post-labeling delays of 1.5 s and 2.5 s were 9.40 and 11.10 mL/100 g/min, respectively.

Conclusion: Three-dimensional pseudocontinuous arterial spin labeling can identify differences in the ocular blood flow of patients with diabetic eyes with and without diabetic macular edema.

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.

Case Report: A 38-year-old male presented to the emergency department with paroxysmal dysphasia for 6h. Brain magnetic resonance (MR) imaging showed acute cerebral infarction of the right corona radiata and right parietal lobe. Three-dimensional time-of-flight MR angiography (3D TOF MRA) revealed severe stenosis of the petrous segment (C1 portion) of the right internal carotid artery and a PTA originating from the right ICA cavernous segment (C4 portion), with a length of approximately 1.8cm and a diameter of approximately 0.2cm. The ICA segments are all named according to the Bouthilier classification. The basilar artery (BA) under union was well developed. The bilateral posterior communicating arteries were also present. One day later, the high-resolution vessel-wall MR demonstrated a dissecting aneurysm in the C1 portion of the right ICA. The length of the dissecting aneurysm is approximately 4.4cm, the diameter of the true lumen at the most severe stenosis is approximately 0.2cm, and the diameter of the false lumen is approximately 0.8cm. Subsequent digital subtraction angiography (DSA) confirmed a dissecting aneurysm in the C1 portion of the right ICA. The patient was treated conservatively and did not undergo interventional surgery. Four months later, head and neck MRA showed that the right ICA blood flow was smooth and that the dissecting aneurysm had disappeared.

The Ethics Committee of Liaocheng People’s Hospital approved the research protocol in compliance with the Helsinki Declaration. Written informed consent was obtained from the individual for the publication of any potentially identifiable images or data included in this article.

Conclusion: Flow alteration with PTA may have influenced the formation of ICA dissection in this patient. Awareness of this is crucial in clinical practice because it can influence treatment options and intervention procedures.

Materials and Methods: This study included 30 pediatric patients aged 1 to 17 years and 30 adult patients over 18 years of age with COVID-19 pneumonia confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR) who have findings related to COVID-19 on Chest Computed Tomography. The CT findings of adult and pediatric patients were compared with a z-test.

Results: Bilateral involvement (p:0.00056), involvement in all five lobes (p<0.00001), and central and peripheral involvement (p:0.01928) were significantly higher in the adult group compared to the pediatric group. In the pediatric group, the frequency of unilateral involvement (p:0.00056), involvement of solitary lobe (p:0.00132), and peripheral involvement (p: 0.01928) were significantly higher than in the adult group. The most common parenchymal finding in adults and pediatric patients was ground-glass opacities (100% and 83%, respectively). Among the parenchymal findings in adults, ground-glass opacities with consolidation (63%) were the second most common finding, followed by air bronchogram (60%) in adults, while in pediatric patients, halo sign (27%) and nodule (27%) were the second most common, followed by the ground-glass opacities with consolidation (23%).

Conclusion: The CT findings of pediatric COVID-19 patients must be well-known as the course of the disease is usually less severe, and the radiological findings are uncertain when compared with adults.

Case Report: A 24-year-old male patient presented with a speech disorder and numbness in his hands and tongue, which developed after flu-like symptoms. An appearance compatible with COVID-19 pneumonia was detected in thorax computed tomography. Delta variant (L452R) was positive in the COVID reverse-transcriptase polymerase chain reaction test (RT-PCR). Cranial radiological imaging revealed intracranial cytotoxic edema, which was thought to be related to COVID-19. Apparent diffusion coefficient (ADC) measurement values in the magnetic resonance imaging (MRI) taken on admission were 228 mm2/sec in the splenium and 151 mm2/sec in the genu. During the follow-up visits of the patient, epileptic seizures developed due to intracranial cytotoxic edema. ADC measurement values in the MRI taken on the 5th day of the patient's symptoms were 232 mm2/sec in the splenium and 153 mm2/sec in the genu. ADC measurement values in the MRI taken on the 15th day were 832 mm2/sec in the splenium and 887 mm2/sec in the genu. He was discharged from the hospital on the 15th day of his complaint with a clinical and radiological complete recovery.

Conclusion: Abnormal neuroimaging findings caused by COVID-19 are quite common. Although not specific to COVID-19, cerebral cytotoxic edema is one of these neuroimaging findings. ADC measurement values are significant for planning follow-up and treatment options. Changes in ADC values in repeated measurements can guide clinicians about the development of suspected cytotoxic lesions. Therefore, clinicians should approach cases of COVID-19 with CNS involvement without extensive systemic involvement with caution.

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.

Case Presentation: The patient underwent gastric endoscopy revealing an extensive lower esophageal varix protruding into the proximal stomach, subsequently treated with banding. The stomach and duodenum were found to contain fresh blood and blood clots indicating acute bleeding.

An urgent CT scan identified active bleeding (extravasation) at segment V and blood accumulation at the confluence of the right and left biliary drains. This was followed by celiac and selective hepatic digital subtraction angiography (DSA).

Conclusion: This case study outlines the occurrence of a hepatic artery pseudoaneurysm six months after percutaneous insertion of bilateral biliary drains. The pseudoaneurysm manifested precisely at the confluence of the right and left drains. The reported delayed complication may have resulted from friction between the drains at the confluence or erosion of the adjacent artery by the drains. The insights gained from this case shed light on the causes and preventive measures for potential delayed complications associated with percutaneous biliary drain placement.

Methods: During a period of 2 years, thirty-seven patients with a clinical diagnosis of FAI were retrospectively enrolled in this study, including 17 men and 20 women, aged 27–62 years. There were 22 right hips and 15 left hips. MRI was done for all patients to identify bony details, labral and chondral abnormalities and to exclude coexisting disorders. The imaging findings were compared with the arthroscopic data.

Results: 15 patients had Pincer FAI, 11 patients had CAM, and 11 patients had combined Cam/Pincer FAI. Labral tear was detected in 100% of patients, 97% had an anterosuperior labral tear. 82% of patients had partial thickness cartilage lesions and 8% had full thickness cartilage lesions. MRI had a sensitivity of 100% compared to hip arthroscopy in detecting labral tear, 60% in detecting cartilage erosion.

Conclusion: Conventional hip MRI detects bony changes in FAI, type of impingement and associated labral tear and cartilage erosions in comparison to the hip arthroscopy.

Methods: A total of 37 consecutive patients with clinically suspected ovarian venous disorders were included. All the patients underwent colour Doppler sonography. CTV was performed in 31 patients, while retrograde phlebography was performed in 6 patients. CT/phlebography was the established diagnostic criterion for ovarian vein disorders. The SPSS 22.0 program was used for statistical analysis. Sensitivity, specificity, and positive and negative predictive values for colour Doppler sonography were calculated. k-test was used to evaluate consistency between colour Doppler sonography and CT/phlebography.

Results: In the 37 patients,18 cases were positive for ovarian vein disorders and 19 cases were negative, as assessed with colour Doppler sonography. The associated lesions included ovarian vein thrombosis (7 cases), ovarian varicocele (3 cases), and ovarian venous leiomyoma (8 cases). The calculated values of sensitivity, specificity, and positive and negative predictive value were 94.4%, 94.7%, 94.4%, and 94.7%, respectively. The overall accuracy rate was 94.9%. The K level of the degree of agreement between CT/phlebography and colour Doppler sonography was 0.892.

Conclusion: Colour doppler sonography can provide sufficient imaging information. In clinical ultrasonography, attention should be paid to recognizing and detecting ovarian venous lesions.

Objectives: This study aimed to characterize the clinical, laboratory, and high-resolution computed tomography (HRCT) findings in patients with mild or moderate infection from SARS-CoV-2 Omicron subvariant BA.2.

Methods: We performed a retrospective study on patients infected with SARS-CoV-2 Omicron subvariant BA.2 between April 4th and April 17th, 2022. The clinical characteristics, laboratory features, and HRCT images were reviewed.

Results: A total of 805 patients were included (411 males and 394 females, median age 33 years old). The infection was mild, moderate, severe, and asymptomatic in 490 (60.9%), 37 (4.6%), 0 (0.0%), and 278 (34.5%) patients, respectively. Notably, 186 (23.1%), 96 (11.9%), 265 (32.9%), 11 (3.4%), 7 (0.9%), and 398 (49.4%) patients had fever, cough, throat discomfort, stuffy or runny nose, fatigue, and no complaint, respectively. Furthermore, 162 (20.1%), 332 (41.2%), and 289 (35.9%) patients had decreased white blood cell counts, reduced lymphocytes, and elevated Creactive protein levels, respectively. HRCT revealed pneumonia in 53 (6.6%) patients. The majority of the lung involvements were ground-glass opacity (50, 94.3%) mostly in the subpleural area. The grade of lung injury was mainly mild (90.6%). Short-term follow-ups showed that most patients with pneumonia recovered.

Conclusion: Most patients with mild or moderate infection from SARS-CoV-2 Omicron subvariant BA.2 were adults, with fever and upper respiratory symptoms as the main clinical presentations. Lower respiratory infection was mild, with ground-glass opacity in the subpleural area as the main finding.

Materials and Methods: Ten patients with surgically resected and pathologically confirmed SANTs were included. Clinical history was reviewed, and gross pathologic, histologic, and immunohistochemical findings were recorded. CT and MRI examinations were evaluated by two radiologists.

Results: Patients included seven men and three women, with a mean age of 42.9±16.7 years. Pathologic features of SANTs involved multiple angiomatous nodules in a radiating pattern with a central stellate fibrous scar and evidence of hemosiderin deposition. 9 cases showed a lobulated demarcated margin, 8 cases a slight hypoattenuating, 1 isoattenuating, and 1 case with two lesions demonstrated a slight hyperattenuating margin, respectively. Multiple scattered punctate calcifications were involved in 2 cases. 5 cases manifested hypointensity on in-phase imaging, 1 iso-intensity, and 4 iso-hypointensity on out-of-phase imaging. Progressive and centripetal enhancement were exhibited in 10 cases, spoke-wheel pattern in 3 cases, and nodular enhancement in 4 cases, respectively. The central fibrous scar was identified in 8 cases during delayed enhancement.

Conclusion: Characteristics of SANTs on CT/MRI reflected the underlying pathology. Hypointensity on DWI and T2WI, and change of signal on T1 chemicalshift imaging were found to be due to hemosiderin deposition and fibrous tissue. Typical feature was a solitary, round, lobulated mass with a fibrous scar. Progressive and centripetal enhancement, spoke-wheel pattern, nodular enhancement, and delayed enhancement of central fibrous scar were observed.

Objective: Nearby the specific therapeutic action, ASMs, like other types of pharmacotherapy, can produce various side effects. In this review, we shall analyze the different pharmaceutical classes of ASMs, their mechanism of action, and their interaction with the respiratory system.

Methods: This manuscript is based on a retrospective review of English publications indexed by Pubmed, UpToDate and datasheets published by the European Medicines Agency and the Food and Drug Administration (FDA), using various terms reminiscent of ASMs and pulmonary function.

Results: ASMs act on organism homeostasis in different ways, acting on lung function directly and indirectly and playing a protective or damaging role. A damaging direct lung involvement ranged from infections, hypersensitivity reactions, and respiratory depression to other structured pulmonary diseases. Meanwhile, a damaging indirect effect, might be constituted by pulmonary artery hypertension. On the other hand, a protective effect might be the expression of developmental processing, decreasing airway remodelling in asthma patients, vascular remodelling in pulmonary hypertension and, nonetheless, anti-inflammatory and immunomodulatory actions.

Conclusion: An adequate awareness of ASMs effects on the respiratory system seems essential for better managing frail individuals or/and those predisposed to respiratory disorders to improve our patients' clinical outcomes.

Case Description: We retrospectively reviewed the Paediatric Intensive Care Unit (PICU) database of the Hong Kong Children’s Hospital and identified cases of suspected and confirmed appendicitis. Clinical features, radiologic findings and final diagnosis of each case were summarized and reported in this case series. We review six anonymized cases of appendicitis managed in a PICU to illustrate the different age spectrum and clinical manifestations of the condition. Rupture of the inflamed appendix, peritonitis and pancreatitis were some of the complications encountered. Crohn’s disease was found in one case as an underlying diagnosis. Also, one girl clinically diagnosed with appendicitis was found to be a case of ruptured hepatoblastoma with no appendicitis (i.e., pseudoappendicitis).

Conclusion: Prompt diagnosis, surgical removal of the inflamed appendix, and use of appropriate antimicrobials when indicated are essential in reducing mortality and morbidity associated with severe appendicitis. Significant premorbid conditions such as acute myeloid leukemia, Mitochondrial Encephalopathy Lactic Acidosis Syndrome (MELAS), inflammatory bowel disease and complications may be present in patients needing intensive care as is illustrated in the present cases. Pseudoappendicitis is an important differential diagnosis. Imaging is crucial and useful in establishing and confirming the diagnosis of appendicitis and pseudo-appendicitis in these PICU cases.

Methods: Literature review through a search in six electronic databases, structured in PICO format, without date restrictions. Looking for studies that used submaximal field walking tests in children and adolescents with congenital heart disease aged 5 to 18 years. Methodological quality, effectiveness and safety and risk of bias were assessed.

Results: Five studies met the eligibility criteria with a sample of 160 individuals with congenital heart disease, and all used the six-minute walk test. Note that different methodologies and modifications are used. Only the clinical trial showed good methodological quality.Four studies had low risk of bias and one study had moderate risk.

Conclusion: Although the six-minute walk test is the only test used as a field test found in our research, there is no standardization in the application of the test, making it difficult to compare the results. In this sense, reducing the limitations and heterogeneity in the application of the test will enable more concrete outcomes and facilitate their reproduction in clinical practice.

With an emphasis on lung illnesses, this article will offer an in-depth understanding of dextran-based delivery systems in respiratory illnesses.

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.

Objective: The aim of this study is an assessment of siRNA-COG3 on proliferation, invasion, and apoptosis of OC cells. In addition, siRNA-COG3 may prevent the growth of OC cancer in mice with tumors.

Methods: Primary OC cell lines will be treated with siRNA-COG3 to assay YKL40 and identified angiogenesis by Tube-like structure formation in HOMECs. The Golgi morphology was analyzed using Immunofluorescence microscopy. Furthermore, the effects of siRNA-COG3 on the proliferation and apoptosis of cells were evaluated using MTT and TUNEL assays. Clones of the HOSEpiC OC cell line were subcutaneously implanted in FVB/N mice. Mice were treated after two weeks of injection of cells using siRNA-COG3. Tumor development suppression was detected by D-luciferin. RT-PCR and western blotting analyses were applied to determine COG3, MT1- MMP, SNAP23, and YKL40 expression to investigate the effects of COG3 gene knockdown.

Results: siRNA-COG3 exhibited a substantial effect in suppressing tumor growth in mice. It dramatically reduced OC cell proliferation and triggered apoptosis (all p < 0.01). Inhibition of COG3, YKL-40, and MT1-MPP led to suppression of angiogenesis and reduction of microvessel density through SNAP23 in OC cells.

Conclusion: Overall, by knockdown of the COG3 gene, MT1-MMP and YKL40 were dropped, leading to suppressed angiogenesis along with decreasing migration and proliferation. SiRNACOG3 may be an ideal agent to consider for clinical trial assessment therapy for OC, especially when an antiangiogenic SNAR-pathway targeting drug.

Objective: Here, we give a comprehensive overview of this quickly developing theranostic application that includes all relevant imaging, diagnostic, therapeutic, and monitoring elements for the management of diabetes and diabetes neuropathy.

Methods: The data for the current study was gathered by searching PubMed and Google Scholar. Several research and review publications from various publishers, including Springer Nature, Bentham Science, PLOS one, MDPI, and ACS Publishing Centre, were evaluated to compile the data.

Result: Recent developments in theranostics have shown promise as alternate management approaches for diabetes and ailments linked to diabetes. Numerous nanotechnology-built biosensors, including multiwalled carbon nanotubes, copper nanowires, zinc oxide tetrapods, and nanoparticle- embedded contact lenses, offer benefits in monitoring diabetic neuropathy.

Conclusion: The potency, usability, and dependability of insulin substitutes have been demonstrated by a variety of innovative methods for the management of diabetes, which includes nanotechnology approaches using Gene-Based Nanoparticles (siRNA), Liposomes, Exosomes/ Extracellular Vesicles, Neuromodulation, and Inhalable Nanoparticles. Over the past few years, the development of various theranostic nanoparticles for Diabetic neuropathy has experienced an unprecedented expansion. Even though much work needs to be done to precisely evaluate the genuine benefits provided by these particles, such as issues with nanotoxicity, theranostic nanoparticles will have a significant impact on the field of nanomedicine.

Aims: The study aimed to assess the role of baseline anamnestic information, clinical parameters, instrumental examination, and serum biomarkers in predicting adverse outcomes of COVID-19 in a hospital setting of Internal Medicine.

Methods: Fifty-two inpatients consecutively admitted to the Unit of Internal Medicine “Baccelli,” Azienda Ospedaliero – Universitaria Policlinico of Bari (February 1 - May 31, 2021) due to confirmed COVID-19 were grouped into two categories based on the specific outcome: good prognosis (n=44), patients discharged at home after the acute phase of the infection; poor prognosis, a composite outcome of deaths and intensive care requirements (n=8). Data were extracted from medical records of patients who provided written informed consent to participate.

Results: The two study groups had similar demographic, anthropometric, clinical, and radiological characteristics. Higher interleukin 6 (IL-6) levels and leucocyte count, and lower free triiodothyronine (fT₃) levels were found in patients with poor than those with good prognosis. Higher IL-6 levels and leucocyte count, lower fT₃ concentration, and pre-existing hypercholesterolemia were independent risk factors of poor outcomes in our study population. A predicting risk score, built by assigning one point if fT₃ < 2 pg/mL, IL-6 >25 pg/mL, and leucocyte count >7,000 n/mm³, revealed that patients totalizing at least 2 points by applying the predicting score had a considerably higher risk of poor prognosis than those scoring <2 points (OR 24.35 (1.32; 448), p = 0.03). The weight of pre-existing hypercholesterolemia did not change the risk estimation.

Conclusion: Four specific baseline variables, one anamnestic (pre-existing hypercholesterolemia) and three laboratory parameters (leucocyte count, IL-6, and fT3), were significantly associated with poor prognosis as independent risk factors. To prevent adverse outcomes, the updated 4-point score could be useful in identifying at-risk patients, highlighting the need for specific trials to estimate the safety and efficacy of targeted treatments.

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.

Objectives: In this regard, the authors intend to investigate the ((2s,6s)-6-ethyl-tetrahydro-2h-pyran- 2-yl) methanol compound (LS20) on pain and acute inflammation.

Methods: Male Swiss mice were evaluated using acetic acid-induced abdominal writhing, formalin, and tail-flick as models of nociceptive evaluation and edema paw, air pouch and cell culture as models of inflammatory evaluation besides the rotarod test for assessment of motor impairment.

Results: The compound showed an effect on the acetic acid-induced abdominal writhing, formalin and tail-flick tests. Studying the mechanism of action, reversion of the antinociceptive effect of the compound was observed from previous intraperitoneal administration of selective and non-selective opioid antagonists on the tail flick test. In addition, the compound induced an antiedematogenic effect and reduced leukocyte migration and the production of pro-inflammatory cytokines in the air pouch model. LS20 was able to maintain cell viability, in addition to reducing cell production of TNF-α and IL-6.

Conclusion: In summary, the LS20 compound presented an antinociceptive effect, demonstrating the participation of the opioid system and an anti-inflammatory effect related to the inhibition of pro-inflammatory cytokine production. The compound also demonstrated safety at the cellular level.

Understanding of the disease has improved through registries, classifying it into five distinct groups with similar histology, pathophysiology, and therapeutic approaches. These groups include PAH, with heritable and idiopathic causes, as well as various clinical subsets involving connective tissue disease, HIV, portopulmonary hypertension, congenital heart disease, and schistosomiasis. Long-term responders to calcium channel blockers, PAH with venous/capillaries involvement, and persistent PH of newborns are categorized under Group 1, now re-classified as IPAH.

A comprehensive workup for suspected patients includes various tests like electrocardiogram, pulmonary function testing, autoimmune workup, HIV testing, echocardiogram, right heart catheterization, and cardiopulmonary exercise testing.

This review emphasizes the disease's definition and epidemiology, delving into each subset and providing updated workup guidelines. The subsequent article will focus on risk stratification and treatment strategies.

Objective: To evaluate the expression levels of circulating miR-21 and -29 in patients with HCM and their association with clinical characteristics and myocardial fibrosis.

Methods: In this case-control study, 27 subjects with HCM, 13 subjects with hypertensive cardiomyopathy, and 10 control subjects were enrolled. Evaluation of patients’ functional capacity was made by the six-minute walk test. Echocardiographic measurements of left ventricle systolic and diastolic function were conducted. Cardiac magnetic resonance late gadolinium enhancement (LGE) -through a semiquantitative evaluation- was used in the assessment of myocardial fibrosis extent in HCM patients. The expression of miR-21 and -29 in peripheral blood samples of all patients was measured via the method of quantitative reverse transcription polymerase chain reaction.

Results: Circulating levels of miR-21 were higher in both hypertensive and HCM (p<0.001) compared to controls, while expression of miR-29 did not differ between the three studied groups. In patients with HCM and LGE-detected myocardial fibrosis in more than 4 out of 17 myocardial segments, delta CT miR-21 values were lower than in patients with myocardial LGE in 3 or fewer myocardial segments (2.71 ± 1.06 deltaCT vs. 3.50 ± 0.55 deltaCT, p<0.04), indicating the higher expression of circulating miR-21 in patients with more extensive myocardial fibrosis.

Conclusion: MiR-21 was overexpressed in patients with HCM and hypertensive cardiomyopathy. Importantly, in patients with HCM, more extensive myocardial fibrosis was associated with higher levels of miR-21.

Methods: HBV-ACLF patients 155 cases undergoing artificial liver treatment were analyzed, and they were sorted into the SCMALT group and the conventional-modal artificial liver treatment (CALT) group. The clinical data of all patients were recorded and the serum levels of interleukin-8 (IL-8), chemokine interferon-inducible protein-10 (IP-10), and interleukin-6 (IL-6) were detected. The changes in the 30-day survival rate, cytokine level, model for end-stage liver disease (MELD) score, and complications of artificial liver treatment were analyzed.

Results: After being followed up for 30 days, 104 patients survived and 51 died. At the end of the whole-course treatment, the decreases in IL-6, IP-10, and IL-8 levels and MELD scores in the SCMALT group were greater than in the CALT group. Cox regression suggested WBC (OR=1.066, 95% CI 1.012-1.123, P=0.017), AT-III activity (OR=0.935, 95% CI 0.907-0.964, p=0.000) at baseline, artificial liver treatment mode (OR=0.362, 95% CI 0.164-0.800, p=0.012), number of artificial liver treatments (OR=0.65695% CI 0.436-0.986, p=0.043), spontaneous peritonitis (OR=0.337, 95% CI 0.165-0.689, p=0.003), and hepatic encephalopathy (OR=0.104, 95% CI 0.028-0.388, p=0.001) were independent influencing factors of 30-day survival rate. SCMALT can significantly prolong the survival period of the patient. No obvious difference was shown in the proportions of bleeding and circulation instability between the two groups (p>0.05).

Conclusion: Compared with the CALT, SCMALT can more effectively remove inflammatory mediators and reduce the MELD score in HBV-ACLF patients, which can obviously ameliorate the prognosis, with less effect on the platelet count.
