Abstract
INTRODUCTION Dysmagnesemia has been demonstrated to be involved in the pathophysiology of kidney diseases and is common in cardiac surgical patients. It remains unknown whether changes of serum magnesium after cardiac surgery affect AKI. We aimed to investigate the association of early postoperative magnesium with cardiac surgery-associated AKI in adults. METHODS We conducted a multicenter retrospective cohort study involving patients who underwent cardiac surgery in the eICU Collaborative Research Database between 2014 and 2015. AKI within 7 days after surgery was defined using both serum creatinine and urine output criteria of Kidney Disease Improving Global Outcomes definition. Postoperative AKI was analyzed using multivariable logistic regression with early postoperative serum magnesium measured within the first 24 h after surgery as a continuous variable and categorically by quartiles. RESULTS Postoperative AKI was identified in 3498 of 6124 (57.1%) patients receiving cardiac surgery. The median (25th-75th percentiles) early postoperative serum magnesium level of the study population was 2.3 (2.0-2.7) mg/dL. Higher serum magnesium level was associated with a higher risk of developing postoperative AKI (adjusted odds ratio (OR), 1.46 per 1 mg/dL increase; 95% confidence interval (CI), 1.31-1.62; p<.001). The multivariable-adjusted ORs (95% CIs) of postoperative AKI across increasing quartiles of serum magnesium were 1.00 (referent), 1.11 (0.95-1.29), 1.30 (1.12-1.52), and 1.72 (1.47-2.02) (p for trend <.001). CONCLUSIONS These data demonstrate a significantly higher incidence of AKI in patients with higher early postoperative serum magnesium who underwent cardiac surgery.

Abstract
BACKGROUND The SARS-CoV-2 (COVID-19) pandemic has resulted in significant changes to health care delivery and the patient's experience in hospital. Changes for those who contracted COVID-19 or were close contacts included isolation and quarantine, visitor restrictions and changes to usual models of care to reduce viral transmission. Traditional models of inpatient rehabilitation utilise communal spaces (e.g. shared gyms and dining rooms) and involve a multidisciplinary team interacting with the patient daily. OBJECTIVES To report the experience of COVID-19 related isolation and quarantine among rehabilitation inpatients and their family members who experienced a nosocomial outbreak and to make recommendations for rehabilitation units. METHODS A qualitative phenomenological methodology using semi-structured telephone interviews. RESULTS 19 semi-structured interviews were conducted comprising of 13 general rehabilitation inpatients and 6 family members. Five themes were established: (1) the impact of social and physical isolation; (2) boredom and limited access to therapy; (3) the impact of technology; (4) inadequate information sharing and (5) positive experiences and things done well. Several novel insights were identified including: the desire for increased social interaction from staff to compensate for a lack of visitors; the impact of physical and cognitive deficits on a patient's ability to reach basic items around their room or call for help, and the unique impact of isolation and quarantine on individuals who have a history of trauma, discrimination or mental illness. CONCLUSIONS This study establishes key areas that should be considered by rehabilitation units globally to adjust traditional models which are not suitable in this pandemic. Strategies to mitigate the impact of isolation include providing training to increase use of technologies such as tablet devices, increased staff social engagement to reduce isolation and tailoring the environment to suit specific patient groups.KEY MESSAGESCOVID-19 related isolation and quarantine has a significant and unique impact on patients with cognitive and physical impairments such as those in inpatient rehabilitation. Patients who are required to isolate in inpatient settings expressed a desire for compensatory increased social interaction from staff and required specific assistance with basic daily tasks while isolated. The study makes key recommendations for other rehabilitation units to integrate into their approach for managing patients required to isolate or quarantine.

Abstract
BACKGROUND Decrease in estimated glomerular filtration rate (eGFR) during Tenofovir disoproxil fumarate (TDF) treatment remains a concern, and few patients experience partial recovery of eGFR. This study aimed to investigate the risk factors for eGFR recovery in patients with and without hypertriglyceridemia. METHODS A total of 203 patients with chronic HBV infection were prospectively recruited and followed up for three years. Data were collected at baseline, first, second, and third years during TDF treatment. RESULTS Most patients achieved normal ALT (80.0% vs. 82.5%) and undetectable HBV DNA (95.0% vs. 95.6%) in both groups (p > 0.05). For patients with hypertriglyceridemia, eGFR and cholesterol did not change significantly during the 3-year follow-up, while triglyceride (TG) decreased significantly in the first year and persisted at a lower level in the subsequent two years. For patients without hypertriglyceridemia, eGFR declined significantly in the first year of treatment, then gradually recovered during the subsequent two years, and eGFR was negatively correlated with TG at the four time points. Fifteen (15/183, 8.2%) patients without hypertriglyceridemia experienced eGFR partial recovery in the third year. Univariate and multivariate analyses showed that baseline eGFR <90 mL/(min·1.73 m2) (p < 0.01; 95% CI: 0.019-0.284) and age (p < 0.01; 95% CI: 0.817-0.960) were independent risk factors for eGFR recovery. CONCLUSION eGFR partially recovered in patients without hypertriglyceridemia during TDF treatment, and TG regulation might be a useful strategy to hinder renal function decline, although larger, confirmatory studies are necessary to validate our findings.Key messagesFor patients with normal triglyceride, eGFR declined significantly at the first year of TDF treatment, then gradually recovered during the subsequent two years, and eGFR was negatively correlated with TG.

Abstract
Despite the evidence of a relationship between loneliness, problematic social networking sites use (PSNSU), and sleep quality, associations between specific PSNSU symptoms and loneliness in individuals with poor vs. good sleep quality and possible gender differences have yet to be understood. We examined the relationships between loneliness and PSNSU symptoms (i.e., preference for online social interaction - POSI, mood regulation, deficient self-regulation, and negative outcomes), and possible moderating effects of gender for individuals with poor vs. good sleep quality. Seven hundred and sixty-three young adults completed an online survey including self-report measures of sleep quality, loneliness, and PSNSU symptoms. Individuals with poor sleep quality reported higher levels of loneliness and greater scores on all PSNSU domains than those with good sleep quality. Slope analyses revealed that in men vs. women with poor sleep quality, greater deficient self-regulation of social networking sites use was associated with lower levels of loneliness. Conversely, in men vs. women with good sleep quality, greater POSI was associated with higher levels of loneliness. Our findings showed that individuals with poor sleep quality are characterized by higher levels of loneliness and more severe PSNSU symptoms that may be the result of sleep disturbance-related metabolic, neural, and hormonal processes. Moreover, our results highlight gender differences for individuals with poor vs. good sleep quality which may help clarify the nature of the association between loneliness and PSNSU.

Abstract
Objectives A key public health intervention is self-isolation for cases and restriction of movement for contacts. This study aimed to identify predictors of compliance behaviour and describe knowledge and attitudes among cases and contacts identified by the national Contact Management Programme to inform the global public health response. Study design Secondary data analysis of anonymised cross-sectional survey data on national sample of cases and close contacts. Methods A sample of 1000 cases and 1000 contacts was calculated to estimate compliance within a margin of error of 3% with 95% confidence. A telephone survey administered by trained interviewers collected information on socio-demographics, compliance behaviours, knowledge, and attitudes to COVID-19 from cases and close contacts. Data analysis included chi-squared statistics and multivariable logistic regression. Results Most cases and contacts complied with public health guidance with similar characteristics in those who did and did not comply. Reasons for non-compliance included exercise, medical appointment, shopping, and work. Cases and contacts reported high levels of understanding about symptoms of COVID-19 and satisfaction with available information. Conclusion Achieving high compliance with public health guidance is feasible and requires political leadership, policy changes and practical solutions.

Abstract
The present study investigated the factors that may be associated with a dysfunctional use of social media use, by exploring the association between adult attachment patterns and problematic social media use and analyzing the sequential mediation of self-esteem, fear of missing out (FoMO), and time spent on social media. A sample of 470 social media users (Mage = 33.76 years; SD = 14.267; 70 % women) completed the Bergen Social Media Addiction Scale, Fear of Missing Out Scale, Rosenberg Self-Esteem Scale, and Relationship Questionnaire. Results showed a path analysis model providing an excellent fit to the data (χ2 = 2.939, p = 0.230; GFI = 0.998, TLI = 0.987, CFI = 0.998, RMSEA = 0.032, SRMR = 0.016). A significant and positive total effect in the associations between preoccupied and fearful attachment patterns and problematic social media use emerged. Both preoccupied and fearful attachment patterns were also related to self-esteem, FoMO, and time spent on social media, which were sequentially associated and were, in turn, significantly related to problematic social media use. Finally, when self-esteem, FoMO, and time spent on social media were added into the model, they totally mediated the relationships between preoccupied and fearful attachment patterns and problematic social media use, suggesting a full multiple mediation model (R2 = 0.33). Such data may provide useful information for clinical practice to develop tailored interventions and prevention programs to address the compensatory and problematic use of social media.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE A key event in the pathogenesis of acute-on-chronic liver failure (ACLF) is the imbalance in the systemic immune response; immunosuppression in patients with ACLF contributes to poor prognosis. The Yi-Qi-Jian-Pi formula (YQJPF) may improve T lymphocyte immune function in patients with ACLF. AIM OF THE STUDY To investigate the immune mechanism of YQJPF in vivo and in vitro. MATERIALS AND METHODS An ACLF rat model was established by injection of CCl4, lipopolysaccharide, and D-galactosamine. We examined the effect of different doses of YQJPF (6.43, 12.87, 25.74 g/kg) on liver injury and immune function in the ACLF rat model. Magnetic-activated cell sorting was used to sort the CD8+ T lymphocytes in the spleen for lymphocyte function detection. In primary CD8+ T lymphocytes and Jurkat cell lines, the expression of mitochondrial function and biogenesis and autophagy related markers were detected using molecular biological methods and flow cytometry analysis. RESULTS YQJPF improved the peripheral blood lymphocyte count and proportion of CD8+ T lymphocytes in ACLF rats, increased pro-inflammatory factors (IL-2, IFN-λ, and TNF-α), and reduced anti-inflammatory factors (IL-10 and TGF β1). YQJPF also improved metabolism and mitochondrial homeostasis in CD8+ T lymphocytes, alleviated lymphocyte immune dysfunction by promoting autophagy, upregulated mitochondrial biogenesis by promoting PGC-1α, NRF-1, and TFAM expression, and regulated the relationship between autophagy and mitochondrial biogenesis via PGC-1α. CONCLUSIONS Our results suggest that YQJPF could improve immune function in a rat model of ACLF, possibly via affecting the homeostasis of lymphatic mitochondria in CD8+ T lymphocytes. YQJPF may enhance lymphocyte mitochondrial biosynthesis and promote lymphocyte autophagy. PGC-1α is a possible upstream regulatory target of YQJPF.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gliomas are common malignant intracranial tumors that have worse prognosis and pose a serious threat to human health. The Kangliu pill (KLP) is an innovative herbal compound from Xuanwu Hospital of Capital Medical University that has been clinically used for the treatment of gliomas for more than 40 years, and is one of the few drugs for primary treatment of this disorder. But the fundamental molecular mechanisms and pathways of KLP are not clear. AIM OF THE STUDY To investigate the therapeutic mechanism of KLP in the treatment of gliomas. MATERIALS AND METHODS An in situ xenograft model of red fluorescent protein-labeled human glioma cell line (U87-RFP) in BALB/c-nu mouse was established, and the therapeutic effect of KLP on gliomas was assessed by tumor weights and fluorescence areas. A quantitative proteomics approach using tandem mass tags combined with liquid chromatography-tandem mass spectrometry was performed to explore differentially expressed proteins (DEPs) in glioma tissues, and bioinformatics analyses including Gene Ontology analysis, pathway analysis, and network analysis were performed to analyze the proteins involved in the network therapeutic mechanisms responsible for key metabolic pathways. Cytological experiments corroborated the above analysis results. RESULTS Network pharmacology approach screened 246 bioactive compounds contained in KLP, targeting 724 proteins and 173 potential targets of KLP for glioma treatment. The important targets obtained after visualizing the PPI network were AKT1, INS, GAPDH, SRC, TP53, etc. The KEGG enrichment results showed that 9 proteins were related to cancer, including Pathways in cancer, PI3K/AKT signaling pathway, etc. KLP had antitumor activity in gliomas, which reduced tumor weights and fluorescence areas. A number of DEPs possibly associated with gliomas were identified through quantitative proteomic techniques. Among these DEPs, 50 (25 upregulated and 25 downregulated) were identified that might be associated with KLP action. Bioinformatics showed that these 50 DEPs were mainly focused on focal adhesion, extracellular matrix (ECM)-receptor interactions, and the PI3K-Akt signaling pathway. Cytological experiments revealed that KLP significantly inhibited the proliferation and promoted apoptosis of U87-MG human glioma cells, and its mechanism was through the inhibition of PI3K/AKT signaling pathway. CONCLUSION Therapeutic effect of KLP was regulation of multiple pathways in the treatment of gliomas. In specific, it interacts through the PI3K-Akt signaling pathway. This work may contribute proteomic insights for further research on the medical treatment of glioma using KLP.

Abstract
Working memory is a key cognitive function that is often implicated in ADHD and may represent an underlying cognitive endophenotype of the disorder. Working memory is related to emotion regulation, which is a common area of impairment in children with ADHD. Given the high rate of comorbid diagnoses with ADHD, children with comorbid internalizing, externalizing, and developmental disorders may present with variable working memory profiles and subsequent emotion regulation deficits. This study aimed to adequately characterize the latent structure of working memory impairments and emotional regulation outcomes in a clinical sample of children ages 6-16 with ADHD. This study also examined the interplay between the identified working memory/emotion regulation patterns, demographic characteristics, and the role of comorbid diagnoses. Results highlighted two distinct, invariant, unrestricted classes of working memory/emotion regulation. Class 1 (Average; 62% of the sample) had significantly lower digit-span scores, and generally persevered emotion regulation functioning per parent/teacher report. Class 2 (Emotionally Dysregulated) had average working memory scores, and elevated emotion regulation problems. The working memory indicators had small correlations with parents (and not teacher) measures of emotion regulation. Finally, latent class membership did not differ by comorbid diagnosis, age, gender, or verbal IQ. Findings elucidate heterogeneity in common domains affected by ADHD and suggest that this heterogeneity may not be due to demographic/comorbidity factors. The role of varying information reports is discussed, and potential assessment and treatment implications are highlighted.

Abstract
Cholesterol is a crucial component of membrane bilayers by regulating their structural and functional properties. Cholesterol traffics to different cellular compartments including mitochondria, whose cholesterol content is low compared to other cell membranes. Despite the limited availability of cholesterol in the inner mitochondrial membrane (IMM), the metabolism of cholesterol in the IMM plays important physiological roles, acting as the precursor for the synthesis of steroid hormones and neurosteroids in steroidogenic tissues and specific neurons, respectively, or the synthesis of bile acids through an alternative pathway in the liver. Accumulation of cholesterol in mitochondria above physiological levels has a negative impact on mitochondrial function through several mechanisms, including the limitation of crucial antioxidant defenses, such as the glutathione redox cycle, increased generation of reactive oxygen species and consequent oxidative modification of cardiolipin, and defective assembly of respiratory supercomplexes. These adverse consequences of increased mitochondrial cholesterol trafficking trigger the onset of oxidative stress and cell death, and, ultimately, contribute to the development of diverse diseases, including metabolic liver diseases (i.e. fatty liver disease and liver cancer), as well as lysosomal disorders (i.e. Niemann-Pick type C disease) and neurodegenerative diseases (i.e. Alzheimer's disease). In this review, we summarize the metabolism and regulation of mitochondrial cholesterol and its potential impact on liver and neurodegenerative diseases.

Abstract
From the starting of the pandemic different transmission routes of the pathogen was brought into the spotlight by researchers from different disciplines. This matter in high-altitudes was more boosted as the main parameters were not exactly realized. In this review we are about to highlight the possibility of consuming contaminated water generated form solar water desalination/disinfection systems in highlands. Three systems including solar still, solar disinfection (which experimented by the authors in 2019 in high altitude) and humidification-dehumidification were consider in this context. Ascribe to the risks of pathogens transmission in solar desalination/disinfection systems where the water resources are heavily polluted in every corner of the world, highlighting the risk of consuming water in high-altitude where there are many other parameters associated with spread of pathogen is of great importance. As it was reported, reliability of solar desalination and solar water disinfections systems against contaminated water by the novel coronavirus remained on the question because the virus can be transmitted by vapor in solar stills due to tiny particle size (60-140 nm) and would not be killed by solar disinfections due to low-temperature of operation <40 °C while for HDH contamination of both water and air by sars-cov-2 could be a concern. Although the SARS-CoV-2 is not a waterborne pathogen, its capability to replicate in stomach and infection of gastrointestinal glandular suggested the potential of transmission via fecal-oral. Eventually, it was concluded that using solar-based water treatment as drinking water in high altitude regions should be cautiously consider and recommendations and considerations are presented. Importantly, this critical review not only about the ongoing pandemic, but it aims is to highlight the importance of produced drinking water by systems for future epidemic/pandemic to prevent spread and entering a pathogen particularly in high-altitude regions via a new routes.

Abstract
BACKGROUND Antibiotic-associated diarrhea (AAD) has had a significant increase in the last years, with limited available effective therapies. Shengjiang Xiexin Decoction (SXD), a classic traditional Chinese medicine formula for treating diarrhea, is a promising alternative for reducing the incidence of AAD. PURPOSE This study aimed to explore the therapeutic effect of SXD on AAD and to investigate its potential therapeutic mechanism by integrated analysis of the gut microbiome and intestinal metabolic profile. METHODS 16S rRNA sequencing analysis of the gut microbiota and untargeted-metabolomics analysis of feces were performed. The mechanism was further explored by fecal microbiota transplantation (FMT). RESULTS SXD could effectively ameliorate AAD symptoms and restore intestinal barrier function. In addition, SXD could significantly improve the diversity of the gut microbiota and accelerate the recovery of the gut microbiota. At the genus level, SXD significantly increased the relative abundance of Bacteroides spp (p < 0.01) and decreased the relative abundance of Escherichia_Shigela spp (p < 0.001). Untargeted metabolomics showed that SXD significantly improved gut microbiota and host metabolic function, particularly bile acid metabolism and amino acid metabolism. CONCLUSION This study demonstrated that SXD could extensively modulate the gut microbiota and intestinal metabolic homeostasis to treat AAD.

Abstract
Demonstration of a very dense or hyper-attenuated liver on the pre-contrast CT images of the abdomen can be an unexpected finding. It may present as a diagnostic challenge if the underlying cause of it is not apparent from the provided clinical history. There are about 12 different pathologic conditions that are associated with deposition of radiopaque elements within the hepatic parenchyma, resulting in diffuse or multi-lobar hyperdense appearance of the liver on abdominal radiographs and CT. Most of them are drug-induced or iatrogenic in nature, while others are the sequelae of genetic disorders like thalassemia, Wilson's disease, and primary hemochromatosis. This pictorial essay will present the CT appearance and etiology of hyper-attenuated liver in various clinical entities.

Abstract
Extracellular vesicles (EVs) are membrane-enclosed vesicles secreted from mammalian cells. EVs act as multicomponent delivery vehicles to carry a wide variety of biological molecular information and participate in intercellular communications. Since elevated levels of EVs are associated with some pathological states such as inflammatory diseases and cancers, probing circulating EVs holds a great potential for early diagnostics. To this end, several detection methods have been developed in which biosensors have attracted great attentions in identification of EVs due to their simple instrumentation, versatile design and portability for point-of-care applications. The concentrations of EVs in bodily fluids are extremely low (i.e. 1-100 per μl) at early stages of a disease, which necessitates the use of signal amplification strategies for EVs detection. In this way, this review presents and discusses various amplification strategies for EVs biosensors based on detection modalities including surface plasmon resonance (SPR), calorimetry, fluorescence, electrochemical and electrochemiluminescence (ECL). In addition, microfluidic systems employed for signal amplification are reviewed and discussed in terms of their design and integration with the detection methods.

Abstract
Hypothyroidism, a commonly encountered thyroid disorder, usually manifests with readily recognizable typical features. However, an unusual presentation of a classic thyroid disorder may hinder accurate diagnosis in certain instances. One such rare initial presentation of hypothyroidism is recurrent hypokalemic paralysis, and existing reports in the literature are sparse. It has been more commonly reported in thyrotoxicosis. We report the case details and clinical outcomes of two middle-aged individuals (a 34-year-old male and a 37-year-old female) with recurrent episodes of hypokalemic paralysis. Their clinical examination revealed pure motor hyporeflexia quadriparesis with hypotonia and diminished deep tendon reflexes without any autonomic dysfunction. They had no significant previous medical history. Biochemical findings revealed hypokalemia in both cases (1.4 and 1.9 mEq/L, respectively) with elevated levels of thyroid‑stimulating hormone and thyroid‑related antibodies in both individuals, thus, confirming the diagnosis of autoimmune hypothyroidism. Immediate treatment with intravenous and oral potassium correction helped in the recovery. Thyroxine supplementation was considered a follow-up treatment, and for a one-year follow-up period there were no complaints of limb weakness reported in both individual.

Abstract
The Covid-19 pandemic has pushed the Intensive Care Units (ICUs) into significant operational disruptions. The rapid evolution of this disease, the bed capacity constraints, the wide variety of patient profiles, and the imbalances within health supply chains still represent a challenge for policymakers. This paper aims to use Artificial Intelligence (AI) and Discrete-Event Simulation (DES) to support ICU bed capacity management during Covid-19. The proposed approach was validated in a Spanish hospital chain where we initially identified the predictors of ICU admission in Covid-19 patients. Second, we applied Random Forest (RF) to predict ICU admission likelihood using patient data collected in the Emergency Department (ED). Finally, we included the RF outcomes in a DES model to assist decision-makers in evaluating new ICU bed configurations responding to the patient transfer expected from downstream services. The results evidenced that the median bed waiting time declined between 32.42 and 48.03 min after intervention.

Abstract
Introduction: Although numerous risk factors for acute kidney injury (AKI) have been identified, their cumulative impact remains unclear. This study aimed to identify perioperative risk factors for early post-transplant AKI on patients and outcomes and to predict AKI using clinical variables.
Material and Methods: A single-center, retrospective cohort study involving 34 pediatric patients and 31 adults who underwent LT between 2015 and 2017.
Results: AKI occurred in 16 (47%) pediatric patients during the first-week post-LT with stage 1, stage 2, and stage 3 AKI frequencies of 43.8, 50, and 6.3%, respectively. Renal replacement therapy (RRT) was initiated in 18.8% of pediatric LT patients. Preoperative liver enzymes and the etiology of liver failure are the most critical factors affecting AKI in pediatric LT patients. AKI occurred in 15 (48%) adult patients during the first-week post-LT with stage 1, stage 2, and stage 3 AKI frequencies of 43%, 21%, and 21%, respectively. The requirement for RRT was seen in 43% of adult LT patients. There were also statistical differences between the two groups regarding the number of patients with preoperative kidney dysfunction (20-80%, p=.047) and mortality rates (6-31 %, p=.047). In adult patients who developed post-LT AKI compared with those who did not develop post-LT AKI, they had significantly higher levels of serum creatinine (sCr) (1.9±1.9 mg/dL vs. 0.7±0.1 mg/dL, p=.013), were given lower amounts of crystalloids (73±32 mL/kg vs. 106±33 mL/kg, p=.018) and had lower urine output (UO) intraoperatively (11±9 mL/kg vs. 20±9 mL/kg, p=.047). There was a higher mortality rate in adult patients with post-LT AKI (89 vs. 11%, p=.003).
Conclusion: The results of our study contribute to raising awareness of the potential risk factors associated with preoperative evaluation, intraoperative and postoperative close follow-up, careful anesthesia management, and early onset of post-LT AKI.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. The mechanisms involved in NAFLD onset are complicated and multifactorial. Recent literature has indicated that altered intestinal barrier function is related to the occurrence and progression of liver disease. The intestinal barrier is important for absorbing nutrients and electrolytes and for defending against toxins and antigens in the enteric environment. Major mechanisms by which the intestinal barrier influences the development of NAFLD involve the altered epithelial layer, decreased intracellular junction integrity, and increased intestinal barrier permeability. Increased intestinal permeability leads to luminal dysbiosis and allows the translocation of pathogenic bacteria and metabolites into the liver, inducing inflammation, immune response, and hepatocyte injury in NAFLD. Although research has been directed to NAFLD in recent decades, the pathophysiological changes in NAFLD initiation and progression are still not completely understood, and the therapeutic targets remain limited. A deeper understanding on the correlation between NAFLD pathogenesis and intestinal barrier regulation must be attained. Therefore, in this review, the components of the intestinal barrier and their respective functions and disruptions during the progression of NAFLD are discussed.

Abstract
Hepatoid adenocarcinoma (HAC) is a rare, malignant, extrahepatic tumor with histologic features similar to those of hepatocellular carcinoma. HAC is most often associated with elevated alpha-fetoprotein (AFP). HAC can occur in multiple organs, including the stomach, esophagus, colon, pancreas, lungs, and ovaries. HAC differs greatly from typical adenocarcinoma in terms of its biological aggression, poor prognosis, and clinicopathological characteristics. However, the mechanisms underlying its development and invasive metastasis remain unclear. The purpose of this review was to summarize the clinicopathological features, molecular traits, and molecular mechanisms driving the malignant phenotype of HAC, in order to support the clinical diagnosis and treatment of HAC.

Abstract
OBJECTIVES Selective Androgen Receptor Modulators (SARMs) social media interest is at an all-time high. The aim of this study is to analyze the: (1) quality; (2) educational content; and (3) reliability of the most relevant YouTube videos on SARMs to explain growing SARMs abuse by recreational and professional athletes. METHODS 'SARMs' was queried (28 November 2021) through the YouTube video library. The top 100 videos filtered by relevance were categorized by source, type of content, educational quality by Global Quality Score (GQS), reliability by Journal of American Medicine Association (JAMA) criteria, YouTube tags, attitude toward SARMs use, and whether the video provided specific support on how to use SARMs. For all outcome variables, descriptive statistics and comparison among source types and category types were performed. RESULTS Mean JAMA score was 1.6 ± 0.7 out of 4. Mean GQS score was 2.5 ± 1.1 out of 5. Patient videos were of lower educational quality than athletic trainer videos (GQS: 2.11 ± 0.95 vs. 2.95 ± 1.00, p < 0.01), and videos categorized as user experience were of lower educational quality than videos categorized as general SARMs information (GQS: 1.92 ± 0.90 vs. 2.72 ± 1.07, p < 0.05). User experience and dosing recommendation videos were statistically significantly more positive in attitude than both general SARMs information and SARMS vs. other PEDs. CONCLUSION Quality, content, and reliability of SARMs YouTube videos was low. Social media likely causes SARMs abuse through disseminating biased SARMs misinformation. These results serve to educate public health oversight bodies, healthcare providers, and sports team members to better identify signs of SARMs abuse, and promote discussion to discourage SARMs abuse.

Abstract
Epstein-Barr virus (EBV)-positive inflammatory follicular dendritic cell (FDC) sarcoma (EBV + IFDCS) is a rare entity, and its histopathological characteristics have not been fully described. Here, we investigated the wide morphologic spectrum and immunophenotype of this tumor with the aim to help avoid misdiagnosis. Thirteen cases of EBV + IFDCS were retrospectively analyzed, combined with a review of 70 cases reported in the literature. The median age of patients was 49 (range, 29 to 67 y). Six patients were male and 7 were female. Most cases (92.3%, 12/13) occurred in the liver or spleen, and only 1 case affected an extra-hepatosplenic site (lung, 7.7%, 1/13). Tumors were assessed for a variety of histologic features and assigned to the following morphologic groups: classic type (53.8%, 7/13), lymphoma-like subtype (38.5%, 5/13), and hemangioma-like subtype (7.7%, 1/13). The classic type had distinct EBV-positive neoplastic cells with a fascicular or storiform growth pattern, variable lymphoplasmacytic infiltrates, and blood vessels. The lymphoma-like subtype had extremely prominent lymphoplasmacytic infiltrates (resembling marginal zone lymphoma with plasmacytoid differentiation) with singly dispersed distinct EBV-positive neoplastic cells, highlighted by in situ hybridization for EBV-encoded small RNA. The hemangioma-like subtype had extremely prominent blood vessels with hyaline and/or fibrinoid degeneration, singly dispersed distinct EBV-positive neoplastic cells, and limited lymphoplasmacytic infiltrates. Immunohistochemically, the neoplastic cells showed variable staining for FDC markers (CD21, CD35, CD23, and SSTR2) and the fibroblastic marker SMA, with the staining ranging from very focal to extensive. The number of EBV-positive neoplastic cells ranged from 80 to 400/HPF. All cases showed variable expression of PD-ligand 1 (PD-L1) (CPS: 5-90). IgG4-positive cells ranged from rare up to 100/HPF. Interestingly, 2 cases satisfied the criteria proposed in a previous study, mimicking IgG4-related disease. EBV + IFDCS is an entity with an extremely wide morphologic spectrum and immunophenotype. Awareness of the spectrum of morphologic presentations of this rare tumor, specifically the lymphoma-like subtype and hemangioma-like subtype, is important for accurate diagnosis.

Abstract
OBJECTIVES Jejunoileal atresia is a common cause of neonatal intestinal obstruction. Results of long-term outcome are very limited. The aim of this study was to describe perioperative and postoperative outcome, and to evaluate long-term gastrointestinal quality of life (QoL) in patients treated for jejunoileal atresia. METHODS We conducted a combined retrospective and cross-sectional observational study of patients treated for jejunoileal atresia during 2001-2019. Perioperative data were registered, and complications were classified according to the Clavien-Dindo classification. To evaluate long-term clinical status and QoL, the PedsQL Gastrointestinal Symptoms Scales questionnaire and a self-designed questionnaire were used. Approval from the Data Protection Office was obtained. RESULTS Seventy patients were included in the retrospective part of the study. Of these, 70% got a primary anastomosis. Concomitant anomalies were registered in 46%. Median length of stay was 28 (5-140) days. Early (<28 days) complication rate was 66%. Early abdominal surgical reinterventions were performed in 11%, most frequently due to anastomotic leak. Late (>28 days) abdominal surgical reinterventions were performed in 21%, and most commonly for bowel obstruction. Overall mortality rate was 4%. Thirty-two patients with median 8 (2-19) years returned the questionnaires. Overall gastrointestinal QoL was good. However, concomitant gastrointestinal anomalies were associated with impaired outcome. Embarrassment of the scar was reported in 38%. Three (9%) patients used medication (laxatives, proton pump inhibitor) for gastrointestinal symptoms. CONCLUSIONS Jejunoileal atresia is associated with significant morbidity during initial treatment. Despite this, the majority of the patients have excellent long-term outcomes.

Abstract
Necroptosis, a regulated form of cell death, is involved in the genesis and development of various life-threatening diseases, including cancer, neurological disorders, cardiac myopathy, and diabetes. Necroptosis initiates with the formation and activation of a necrosome complex, which consists of RIPK1, RIPK2, RIPK3, and MLKL. Emerging studies has demonstrated the regulation of the necroptosis cell death pathway through the implication of numerous post-translational modifications, namely ubiquitination, acetylation, methylation, SUMOylation, hydroxylation, and others. In addition, the negative regulation of the necroptosis pathway has been shown to interfere with brain homeostasis through the regulation of axonal degeneration, mitochondrial dynamics, lysosomal defects, and inflammatory response. Necroptosis is controlled by the activity and expression of signaling molecules, namely VEGF/VEGFR, PI3K/Akt/GSK-3β, c-Jun N-terminal kinases (JNK), ERK/MAPK, and Wnt/β-catenin. Herein, we briefly discussed the implication and potential of necrosome activation in the pathogenesis and progression of neurological manifestations, such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, traumatic brain injury, and others. Further, we present a detailed picture of natural compounds, micro-RNAs, and chemical compounds as therapeutic agents for treating neurological manifestations.

Abstract
BACKGROUND Dizziness and balance problems are common symptoms in patients with cervical radiculopathy. OBJECTIVE To evaluate the effect of neck surgery postoperatively combined with either structured rehabilitation or standard approach in patients with cervical radiculopathy and dizziness and/or balance problems, and investigate factors influencing dizziness and balance at 6-month follow-up. METHODS Individuals (n = 149) with cervical radiculopathy and dizziness and/or balance problems were randomized preoperatively to structured postoperative rehabilitation or standard postoperative approach. Outcomes were intensity of dizziness and subjective balance, and clinical measures of balance. RESULTS Self-reported measures improved at three months (p ˂ 0.001 to p = .007) and the standing balance at six months (p = .008). No between-group differences. Baseline values, neck pain, and physical activity level explained 23-39% of the variance in 6-month outcomes for self-reported measures. Baseline values and physical activity level explained 71% of the variance in walking balance, and lower baseline scores were significantly associated with standing balance impairments (OR 0.876). CONCLUSION Patients improved significantly in dizziness and subjective balance intensity shortly after surgery, and in standing balance at 6 months, independent of postoperative rehabilitation. Neck pain, physical activity, and neck muscle function influenced dizziness and balance, although preoperative values and neck pain were of most importance for 6-month outcomes.

Abstract
Unvalidated theories have been proposed for the etiopathogenesis of masticatory myofascial temporomandibular disorders (mTMD). Modalities such as cone-beam computed tomography/computed tomography and MRI contributes little to the diagnosis of mTMD. Diagnosing mTMD is based on the recognition of "familiar pain" presentation in the masticatory myofascial tissue. This assessment tool contributes little our understanding of the underlying disease process. Thus, management of mTMD is empirical and arbitrary. Exploring emerging technologies to identify biomarkers and objectively assess myofascial tissue physiology in disease and health may be key in moving the diagnosis of mTMD from the pragmatic paradigm to an evidence-based paradigm.

Abstract
The microbiome has been proven to be associated with many diseases and has been used as a biomarker and target in disease prevention and intervention. Currently, the vital role of the microbiome in pregnant women and newborns is increasingly emphasised. In this review, we discuss the interplay of the microbiome and the corresponding immune mechanism between mothers and their offspring during the perinatal period. We aim to present a comprehensive picture of microbial transmission and potential immune imprinting before and after delivery. In addition, we discuss the possibility of in utero microbial colonisation during pregnancy, which has been highly debated in recent studies, and highlight the importance of the microbiome in infant development during the first 3 years of life. This holistic view of the role of the microbial interplay between mothers and infants will refine our current understanding of pregnancy complications as well as diseases in early life and will greatly facilitate the microbiome-based prenatal diagnosis and treatment of mother-infant-related diseases.

Abstract
This study observed the cutaneous analgesic effect of adrenergic agonists when combined with lidocaine. We aimed at the usefulness of four adrenergic agonists and epinephrine as analgesics or as tools to prolong the effect of local anesthetics using a model of cutaneous trunci muscle reflex (pinprick pain) in rats. We showed that subcutaneous four adrenergic agonists and epinephrine, as well as the local anesthetic bupivacaine and lidocaine, developed a concentration-dependent cutaneous analgesia. The rank order of the efficacy of different compounds (ED50 ; median effective dose) was epinephrine [0.013 (0.012-0.014) μmol] > oxymetazoline [0.25 (0.22-0.28) μmol] > naphazoline [0.42 (0.34-0.53) μmol] = bupivacaine [0.43 (0.37-0.50) μmol] > xylometazoline [1.34 (1.25-1.45) μmol] > lidocaine [5.86 (5.11-6.72) μmol] > tetrahydrozoline [6.76 (6.21-7.36) μmol]. The duration of full recovery caused by tetrahydrozoline, oxymetazoline, or xylometazoline was greater (P < 0.01) than that induced via epinephrine, bupivacaine, lidocaine, or naphazoline at equianesthetic doses (ED25 , ED50 , and ED75 ). Co-administration of lidocaine (ED50 ) with four adrenergic agonists or epinephrine enhanced the cutaneous analgesic effect. We observed that four adrenergic agonists and epinephrine induce analgesia by themselves, and such an effect has a longer duration than local anesthetics. Co-administration of lidocaine with the adrenergic agonist enhances the analgesic effect, and the cutaneous analgesic effect of lidocaine plus naphazoline (or oxymetazoline) is greater than that of lidocaine plus epinephrine.

Abstract
Neuropathic arthropathy (NA) is a long-term progressive disorder that causes joint destruction in the existence of a neurologic deficit. Minor injuries and fractures are commonly overlooked until the visible joint deterioration becomes persistent. Syringomyelia is one of the important causes of NA. The appearance of clinical signs in syringomyelia is caused by longitudinal cysts formed in the cervical and cervicothoracic regions of the spinal cord. Depending on the existence of the underlying disorder, the number and localization of the syrinxes, a range of symptoms, involving pain, sensation deficit, loss of motor function, and deep tendon reflex abnormality, emerge. The case is here described of a 68-year-old female patient with shoulder NA following syringomyelia, who partially responded to the rehabilitation program. Furthermore, the available case reports were comprehensively reviewed on Web of Science, Scopus, and PubMed/Medline. Furthermore, the available case reports were comprehensively evaluated on Web of Science, Scopus, and PubMed/Medline. Thus, we aimed to present the demographic characteristics, symptoms, physical examination signs, treatment, and follow-up parameters of syringomyelia-related shoulder NA cases.

Abstract
It is very rare for different types of urological tumours to occur together, and it is even rarer for chromophobe renal cell carcinoma (CRCC) to be combined with ipsilateral ureteral urothelial carcinoma (UUC), and the symptoms are relatively homogeneous, mostly presenting as symptoms that can be observed in malignant tumours alone, and therefore are often easily missed. In the present study, a case of a patient who was admitted to the hospital for more than 3 months with no obvious cause of terminal carnivorous hematuria was reported, and ureteral carcinoma was considered in the preoperative diagnosis but not renal carcinoma. After completion of preoperative tests, laparoscopic right nephrectomy and right ureterectomy was performed. The postoperative pathological diagnosis was CRCC of the right side and low-grade UUC of the right side, and the patient did not show any significant abnormality at the postoperative follow-up. By discussing this case and reviewing the relevant literature, the present study provides clinicians with more insight.

Abstract
OBJECTIVE Individuals infected with hepatitis B virus (HBV) are at increased risk of reactivation when they receive immunosuppressive therapies. Although exogenous corticosteroid use as immunosuppressive therapy is elaborated in current guidelines on HBV reactivation, Cushing's syndrome (CS) with endogenous hypercortisolemia is not addressed. We aimed to investigate the prevalence of HBV infection and discuss the necessity of antiviral prophylaxis in patients with CS as in other immunosuppressed patients. DESIGN AND PATIENTS We included 72 patients with CS (Adrenocorticotropic hormone (ACTH) dependent or independent) who were screened for HBV between 2016 and 2021. Patients were categorized into three groups: overt, mild autonomous cortisol secretion (MACS), and remission according to the cortisol burden. Changes in patients' HBV serology and clinical findings over time were analyzed retrospectively. RESULTS Twenty-six patients had overt hypercortisolism, 18 had mild autonomous cortisol secretion and 28 patients were in remission. Nineteen (26.3%) patients were anti-HBc IgG positive, 4 of them were chronic HBV and 15 were isolated anti-HBc IgG positive. HBsAg was positive in four (5.5%) of the patients, who were all compatible with inactive chronic HBV. While two patients developed HBV reactivation, HBV flare was observed in one patient. CONCLUSION Since it is not always possible to achieve rapid remission in CS and these patients have long-term hypercortisolemia, we suggest that consensus should be reached on HBV serological assessment, standardization of follow-up, and planning of HBV prophylaxis in required instances in patients with CS especially in regions with a high prevalence of HBV infection.

Abstract
Serum osmolality is the sum of the osmolalities of every single dissolved particle in the blood such as sodium and associated anions, potassium, glucose, and urea. Under normal conditions, serum sodium concentration is the major determinant of serum osmolality. Effective blood osmolality, so-called blood tonicity, is created by the endogenous (e.g., sodium and glucose) and exogenous (e.g., mannitol) solutes that are capable of creating an osmotic gradient across the membranes. In case of change in effective blood osmolality, water shifts from the compartment with low osmolality into the compartment with high osmolarity in order to restore serum osmolality. The difference between measured osmolality and calculated osmolarity forms the osmolal gap. An increase in serum osmolal gap can stem from the presence of solutes that are not included in the osmolarity calculation, such as hypertonic treatments or toxic alcoholic ingestions. In clinical practice, determination of serum osmolality and osmolal gap is important in the diagnosis of disorders related to sodium, glucose and water balance, kidney diseases, and small molecule poisonings. As blood hypertonicity exerts its main effects on the brain cells, neurologic symptoms varying from mild neurologic signs and symptoms to life-threatening outcomes such as convulsions or even death may occur. Therefore, hypertonic states should be promptly diagnosed and cautiously managed. In this review, the causes and treatment strategies of hyperosmolar conditions including hypernatremia, diabetic ketoacidosis, hyperglycemic hyperosmolar syndrome, hypertonic treatments, or intoxications are discussed in detail to increase awareness of this important topic with significant clinical consequences.

Abstract
BACKGROUND A subgroup of patients with HER2-positive metastatic gastric and gastroesophageal junction cancers shows long-term response under trastuzumab maintenance monotherapy. Obviously, HER2 status alone is not able to identify these patients. We performed this study to identify potential new prognostic biomarkers for this long-term responding patient group. PATIENTS AND METHODS Tumour samples of 19 patients with HER2-positive metastatic gastric and gastroesophageal junction cancer who underwent trastuzumab treatment were retrospectively collected from multiple centres. Patients were divided into long-term responding (n = 7) or short-term responding group (n = 12) according to progression-free survival (PFS≥12 months vs. PFS < 12 months). Next-generation sequencing and microarray-based gene expression analysis were performed along with HER2 and PD-L1 immunohistochemistry. RESULTS Long-term responding patients had significantly higher PD-L1 combined positive scores (CPS) and CPS correlated with longer progression-free survival. PD-L1 positivity (CPS ≥ 1) was further associated with an increased CD4+ memory T-cell score. The ERBB2 copy number as well as the tumour mutational burden could not discriminate between short-term and long-term responding patients. Genetic alterations and coamplifications in HER2 pathway associated genes such as EGFR, which were connected to trastuzumab resistance, were present in 10% of the patients and equally distributed between the groups. CONCLUSION The study highlights the clinical relevance of PD-L1 testing also in the context of trastuzumab treatment and offers a biological rational by demonstrating elevated CD4+ memory T-cells scores in the PD-L1-positive group.

Abstract
Myeloid/lymphoid neoplasms with eosinophilia (MLN-eos) are rare haematological neoplasms primarily affecting adults. The heterogeneous clinical picture and the rarity of the disease, especially in children, may delay an early diagnosis. MLN-eos are characterized by constitutive tyrosine kinase (TK) activity due to gene fusions. It is thus of importance to obtain a prompt genetic diagnosis to start a specific therapy. Here, we outline the clinical, genetic, and biochemical background of TK driven MLN-eos and report two extremely rare paediatric cases of MLN-eo, the used diagnostic methods, therapy and clinical outcomes. Our results demonstrate that, standard cytogenetic and molecular methods may not be sufficient to diagnose MLN-eo due to cytogenetically cryptic aberrations. We therefore recommend performing additional evaluation with fluorescence in-situ hybridization and molecular genetic methods (array-based comparative genomic hybridization and RNA sequencing) which will lead to the correct diagnosis. Following this diagnostic route we detected a TNIP1::PDGFRB and a PCM1::FGFR1 fusion in our patients. Thus, genetic diagnosis must be precise and quick in order to initiate adequate therapies with tyrosine kinase inhibitors or HSCT.

Abstract
BACKGROUND/AIM There are no epidemiological reports focused on the oral and maxillofacial surgery emergency department in the West China Hospital of Stomatology. The aim of this study was to analyse the epidemiological characteristics of emergency patients admitted for Trauma and Plastic Surgery Department of the West China Hospital of Stomatology from 2016-2019. MATERIALS AND METHODS In this retrospective study, 5220 patients with complete medical records were evaluated. The following data were collected: gender, age, etiology, disease type distribution, anatomic injury site and treatment modality. RESULTS There were 3046 males and 2174 females (ratio 1.40:1), with an average age of 16.2 years. The largest group was children aged between 3 and 6 years old (28.3%). Maxillofacial injuries were the most common condition (87.3%), which mostly occurred on the forehead (29.7%), followed by the lips (27.8%). A fall was the leading cause of injury (59.9%), especially in patients younger than 6 years old. There were 327 cases of maxillofacial space infections (MSI), and the mandibular third molars were the most common tooth associated with odontogenic infections (36.2%). Univariable analysis identified that multiple-space infection, visit time and systemic conditions were the risk factors for being admitted to the hospital for treatment. There were 116 patients (2.2%) with bleeding as the main complaint, and most of the maxillofacial bleeding patients could be stopped by compression (52.6%). CONCLUSION Males and children aged younger than 6 years were the highest risk populations. Trauma accounted for the majority of emergency patients in maxillofacial surgery. Most maxillofacial injuries involved the forehead and were mainly caused by accidental falls. The proportion of MSI was not high, but serious cases may be life-threatening. The causes of bleeding were diverse, and the bleeding was easy to control.

Abstract
Vitiligo is the most common depigmenting disease characterized by achromic macules due to selective loss of melanocytes. The pathogenesis remains poorly elucidated, and multiple hypotheses exist regarding its pathogenesis. Evidence suggests that stress on melanocytes can result in activation of the immune system, and involvement of both activated cluster of differentiation (CD8+) cytotoxic and CD4+ T cells in the dysfunction, depigmentation, and apoptosis of melanocytes. Recent studies show that the interleukin 17 (IL-17) axis plays a central role in the pathogenesis of the disease. IL-17 is an important regulatory effector cytokine in this pathway. The aim of this study was to evaluate the association of IL-17A rs4711998 (-832A/G), IL-17A rs2275913 (-197G/A), and IL-17F rs763780 (7488A/G) with vitiligo in a Northeastern Mexican population. This was a case-control study and included 116 patients with vitiligo and 116 control subjects. Genotype characterization of IL-17A rs4711998 (-832A/G), IL-17A rs2275913 (-197G/A), and IL-17F rs763780 (7488A/G) was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. A p ≤ 0.05 was considered significant. It was observed that the combination of the genotypes GG/GA for IL-17F rs763780 (7488A/G) was associated with an increased risk for the development of vitiligo (OR 2.0943, 95% Cl 1.2375-3.5445, p = 0.0056). Regarding IL-17A rs4711998 (-832A/G) and IL-17A rs2275913 (-197G/A) genotyping, no association with vitiligo development was found. In conclusion, the SNP rs763780 in the IL-17F gene appears to be a risk factor for vitiligo development in this Mexican population and it may be useful in future studies, especially for the development of new therapies.

Abstract
PURPOSE The predictors of muscle necrosis after acute compartment syndrome (ACS) remain debated. This study aimed to investigate the predictors for muscle necrosis in ACS patients. METHODS We collected data on ACS patients following fractures from January 2010 to November 2022. Patients were divided into the muscle necrosis group (MG) and the non-muscle necrosis group (NG). The demographics, comorbidities, and admission laboratory indicators were computed by univariate analysis, logistic regression analysis, and receiver-operating characteristic (ROC) curve analysis. RESULTS In our study, the rate of MN was 37.6% (83 of 221). Univariate analysis showed that numerous factors were associated with muscle necrosis following ACS. Logistic regression analysis indicated that crush injury (p = 0.007), neutrophil (NEU, p = 0.001), creatine kinase myocardial band (CKMB, p = 0.047), and prothrombin time (PT, p = 0.031) were risk factors. Additionally, ROC curve analysis identified 11.415 109/L, 116.825 U/L, and 12.51 s as the cut-off values for NEU, CKMB, and PT to predict muscle necrosis, respectively. Furthermore, the combination of NEU, CKMB, and PT had the highest diagnostic accuracy. CONCLUSIONS Our findings showed that crush injury and the level of NEU, CKMB, and PT were risk factors for muscle necrosis after ACS. Additionally, we also identified the cut-off values of NEU, CKMB, and PT and found the combination of crush injury, PT, and NEU with the highest diagnostic accuracy, helping us individualize the assessment risk of muscle necrosis to manage early targeted interventions.

Abstract
Although the anatomical basis of the pathogenesis of sinus node dysfunction (SND) and atrial fibrillation (AF) is located primarily in the left and right atria, increasing evidence suggests a strong correlation between SND and AF, in terms of both clinical presentation and formation mechanisms. However, the exact mechanisms underlying this association are unclear. The relationship between SND and AF may not be causal, but is likely to involve common factors and mechanisms, including ion channel remodeling, gap junction abnormalities, structural remodeling, genetic mutations, neuromodulation abnormalities, the effects of adenosine on cardiomyocytes, oxidative stress, and viral infections. Ion channel remodeling manifests primarily as alterations in the "funny" current (If) and Ca2+ clock associated with cardiomyocyte autoregulation, and gap junction abnormalities are manifested primarily as decreased expression of connexins (Cxs) mediating electrical impulse propagation in cardiomyocytes. Structural remodeling refers primarily to fibrosis and cardiac amyloidosis (CA). Some genetic mutations can also cause arrhythmias, such as SCN5A, HCN4, EMD, and PITX2. The intrinsic cardiac autonomic nervous system (ICANS), a regulator of the heart's physiological functions, triggers arrhythmias.In addition, we discuss arrhythmias caused by viral infections, notably Coronavirus Disease 2019 (COVID-19). Similarly to upstream treatments for atrial cardiomyopathy such as alleviating CA, ganglionated plexus (GP) ablation acts on the common mechanisms between SND and AF, thus achieving a dual therapeutic effect.

Abstract
Gastrointestinal bleeding or perforation following influenza infection is rare. We encountered a pediatric case of hemorrhagic duodenal ulcer following influenza A infection. The patient was a 1‐year and 4‐month‐old boy who was diagnosed with influenza A infection and treated with laninamivir octanoate. After inhalation, he had diarrhea, poor appetite, and melena. The next day, he had hematochezia and developed hemorrhagic shock. Contrast‐enhanced computed tomography showed extravasation in the descending part of the duodenum. Esophagogastroduodenoscopy revealed spurting bleeding from a Dieulafoy's lesion on the oral side of the major papilla, and he underwent hemostasis by clipping. From the bulb to the descending part of the duodenum, the mucosa appeared atrophic with spotty redness on the circular folds and multiple and irregularly shaped erosions. Almost all mucosal lesions had healed by the eighth day, and he was monitored as an outpatient for more than one year without re‐bleeding. Intestinal ischemia, viral invasion, and drug reaction of laninamivir octanoate may be involved in duodenal mucosal injury. Acute duodenal ulcers may occur in children with influenza infection, especially young children.

Abstract
The pandemic COVID-19 has spread widely throughout the globe and has been responsible for millions of deaths worldwide. Recently, it has been identified that there is no specific and 100% effective treatment available to manage the infection especially for the severe cases. A significant amount of research efforts and clinical trials have been undertaken globally and many more are underway to find the potential treatment option. Earlier, convalescent plasma or hyperimmune immunoglobulin was effectively used in the treatment of many endemic or epidemic viral infections as a part of passive immunization. In this article, we have touched upon the immunopathology of COVID-19 infection, a basic understanding of convalescent plasma, it's manufacturing as well as evaluation, and have reviewed the scientific developments focussing on the potential of convalescent plasma vis-à-vis other modalities for the management of COVID-19. The article also covers various research approaches, clinical trials conducted globally, and the clinical trials which are at various stages for exploring the efficacy and safety of the convalescent plasma therapy (CPT) to predict its future perspective to manage COVID-19.

Abstract
BACKGROUND Spontaneous jugular venous ectasia (SJVE) is characterized by dilation of the internal jugular vein (IJV) and external jugular vein. It is generally considered a benign anomaly. There is no accepted categorization for this disorder. METHODS We conducted a case series study and a systematic review of available articles on SJVE to understand the main characteristics, clinicopathologic classifications, and therapeutic approaches. RESULTS From January 2001 to December 2021, 14 patients in our hospital were analyzed. A total of 110 original articles (295 cases/311 lesions) were included in the systematic review. We proposed a classification and categorized SJVE into 4 main types (type I-IV) plus one (type V) in which the specific ectasia was located around the jugular bulb at the IJV. CONCLUSIONS Conservative treatment is preferred for patients with type I (without thrombus) SJVE and asymptomatic patients who can be treated without anticoagulants. The therapeutic efficiency of surgery was high, and the best surgical modalities were chosen according to the type of SJVE.

Abstract
PURPOSE OF REVIEW The coronavirus disease 2019 pandemic demonstrated broad utility of pathogen sequencing with rapid methodological progress alongside global distribution of sequencing infrastructure. This review considers implications for now moving clinical metagenomics into routine service, with respiratory metagenomics as the exemplar use-case. RECENT FINDINGS Respiratory metagenomic workflows have completed proof-of-concept, providing organism identification and many genotypic antimicrobial resistance determinants from clinical samples in <6 h. This enables rapid escalation or de-escalation of empiric therapy for patient benefit and reducing selection of antimicrobial resistance, with genomic-typing available in the same time-frame. Attention is now focussed on demonstrating clinical, health-economic, accreditation, and regulatory requirements. More fundamentally, pathogen sequencing challenges the traditional culture-orientated time frame of microbiology laboratories, which through automation and centralisation risks becoming increasingly separated from the clinical setting. It presents an alternative future where infection experts are brought together around a single genetic output in an acute timeframe, aligning the microbiology target operating model with the wider human genomic and digital strategy. SUMMARY Pathogen sequencing is a transformational proposition for microbiology laboratories and their infectious diseases, infection control, and public health partners. Healthcare systems that link output from routine clinical metagenomic sequencing, with pandemic and antimicrobial resistance surveillance, will create valuable tools for protecting their population against future infectious diseases threats.

Abstract
Immune checkpoint inhibitors have revolutionized management of advanced malignancies. However, their use is frequently complicated by immune related adverse events (irAEs), immune checkpoint inhibitor enterocolitis (IMEC) being the most common toxicity. IMEC is a distinct form of bowel inflammation that is highly reminiscent of idiopathic inflammatory bowel disorders (Crohn's disease, ulcerative colitis, and microscopic colitis). In this review, we highlight the similarities and differences in the pathophysiology, clinical presentation, evaluation, and management of these overlapping immune inflammatory bowel disorders. IMEC is an inflammatory bowel disease-like irAE that occurs as an outcome of disruption of intestinal immune surveillance and gut dysbiosis. Clinical and endoscopic presentation of both entities is strikingly similar, which often guides management. Though well established in inflammatory bowel disease, little is known about the long term outcomes of IMEC.
