Abstract
Background and study aims We aimed to evaluate the diagnostic performance of magnifying endoscopy with narrow-band imaging (M-NBI) in superficial non-ampullary duodenal epithelial tumors (SNADETs) regarding the absence or presence of biopsy before M-NBI diagnosis. Patients and methods Clinicopathological data were retrospectively reviewed for 99 SNADETs from 99 patients who underwent endoscopic resection. The 99 tumors were divided into the non-biopsy group (32 lesions not undergoing biopsy before M-NBI examination) and the biopsy group (67 lesions undergoing biopsy before M-NBI examination). We investigated the correlation between the M-NBI diagnosis and the histopathological diagnosis of the SNADETs in both groups. Results According to the modified revised Vienna classification, 31 tumors were classified as category 3 (C3) (low-grade adenoma) and 68 as category 4/5 (C4/5) (high-grade adenoma/cancer). The accuracy, sensitivity, and specificity of preoperative M-NBI diagnoses in the non-biopsy group vs the biopsy group were 88 % (95 % confidence interval: 71.0 - 96.5) vs 66 % (51.5 - 75.5), P = 0.02; 95 % (77.2 - 99.9) vs 89 % (76.4 - 96.4), P = 0.39; and 70 % (34.8 - 93.3) vs 14 % (3.0 - 36.3), P < 0.01, respectively. Notably, in the biopsy group, the specificity of M-NBI in SNADETs was low at only 14 % because we over-diagnosed most C3 lesions as C4/5. M-NBI findings might have been compromised by the previous biopsy procedure itself. Conclusions In the non-biopsy group, the accuracy of M-NBI in SNADETs was excellent in distinguishing C4/5 lesions from C3. The M-NBI findings in SNADETs should be evaluated while carefully considering the influence of a previous biopsy.

Abstract
AIM The aim was to investigate the RAS discordance between initial and recurrent metastasectomy specimens in metastatic colorectal cancer (mCRC) patients treated with chemotherapy (CT) plus biological agents in a first-line setting. METHODS Patients who had been treated with CT plus bevacizumab or cetuximab or panitumumab followed by R0 resection for potentially resectable colorectal cancer liver metastases were scanned. Among these, patients who developed resectable new metastases after a disease-free interval longer than 6 months were included in the study. We compared the RAS mutation status between the first biopsy and the second metastasectomy specimen. RESULTS A total of 82 mCRC patients treated with CT plus biological agents in a first-line setting were included in the study. The first biopsy assessment showed wild-type RAS tumours in 39 (47.6%) patients and mutant RAS tumours in 43 (52.4%) patients. The mean time for new operable liver metastasis after R0 resection was 15.5 months. In the second metastasectomy specimens, the numbers of wild-type and mutant RAS tumours were 30 (36.6%) and 52 (63.4%), respectively. The comparison with the first biopsy specimens showed RAS status conversions in 17 (20.7%) patients. Univariate comparison between patients with and without RAS status conversion revealed that grade, pathological T stage, wild-type RAS tumour and longer biological agent use time in the first-line treatment were significant factors for RAS conversion. CONCLUSION Our results suggest that re-biopsy is needed for an optimal second-line treatment decision in mCRC patients regardless of backbone biological agent, especially in patients with wild-type RAS mCRC.

Abstract
Major trauma is one of the leading causes of morbidity and mortality in young adults. The impact of disability on the quality of life and functionality in this younger population is worrisome. This remains a major public health concern across the globe. Immediate and early deaths account for nearly 80% of trauma deaths occurring within the first few hours of injury to the first few days, usually because of traumatic brain injury or major exsanguination and subsequently due to shock or hypoxia. Worldwide adoption of comprehensive trauma systems and evolving models of trauma care including prehospital interventions have led improvements in trauma and critical care over the last few decades. Resuscitation and damage control orthopaedics are two key pillars in the management of polytrauma patient. Trauma-related coagulopathy can be an emerging complication during resuscitation of such patients which should be recognized early so appropriate corrective measures can be undertaken. We describe the evolving models of care in the management of polytrauma and trauma associated coagulopathy.

Abstract
BACKGROUND The novel SARS-CoV-2 has caused the coronavirus disease 2019 (COVID-19) pandemic. Currently, with insufficient worldwide vaccination rates, identifying treatment solutions to reduce the impact of the virus is urgently needed. METHOD An adaptive, multicentric, open-label, and randomized controlled phase I/II clinical trial entitled the "SENTAD-COVID Study" was conducted by the Abu Dhabi Stem Cells Center under exceptional conditional approval by the Emirates Institutional Review Board (IRB) for COVID-19 Research Committee from April 4th to July 31st, 2020, using an autologous peripheral blood non-hematopoietic enriched stem cell cocktail (PB-NHESC-C) administered by compressor (jet) nebulization as a complement to standard care therapy. The primary endpoints include safety and efficacy assessments, adverse events, the mortality rate within 28 days, and the time to clinical improvement as measured by a 2-point reduction on a seven-category ordinal scale or discharge from the hospital whichever occurred first. RESULTS The study included a total of 139 randomized COVID-19 patients, with 69 in the experimental group and 70 in the control group (standard care). Overall survival was 94.20% for the cocktail-treated group vs. 90.27% for the control group. Adverse events were reported in 50 (72.46%) patients receiving PB-NHESC-C and 51 (72.85%) in the control group (p = 0.9590), with signs and symptoms commonly found in COVID-19. After the first 9 days of the intervention, 67.3% of cocktail-treated patients recovered and were released from hospitals compared to 53.1% (RR = 0.84; 95% CI, 0.56-1.28) in the control group. Improvement, i.e., at least a 2-point reduction in the severity scale, was more frequently observed in cocktail-treated patients (42.0%) than in controls (17.0%) (RR = 0.69; 95% CI, 0.56-0.88). CONCLUSIONS Cocktail treatment improved clinical outcomes without increasing adverse events. Thus, the nebulization of PB-NHESC-C was safe and effective for treatment in most of these patients. TRIAL REGISTRATION ClinicalTrials.gov. NCT04473170. It was retrospectively registered on July 16th, 2020.

Abstract
Follicular dendritic cell sarcoma (FDCS) can be divided into the conventional type, and the inflammatory pseudotumor (IPT)-like variant type. Epstein-Barr virus (EBV) infection is considered to be closely associated with the pathogenesis of IPT-like variant of FDCS. Hepatic FDCS has an exceedingly low incidence of only 29 cases reported, with most of these tumors being classified as the IPT-like type. We report a case of an IPT-like variant of FDCS of the liver in a 61-year old man who presented with no marked symptoms. The patient underwent laparoscopic surgery for the mass and was well during a 13-month follow-up periods. The postoperative pathological examination found a proliferation of spindle cells and a diffuse infiltration of inflammatory cells within the tumor. Immunohistochemistry revealed that neoplastic cells were positive for CD23, clusterin, fascin, and PD-L1, and weakly positive for CD35, SMA, and D2-40. The infiltrating lymphocytes were strongly positive for PD1, and IgG4-positive plasma cells were less than 10 cells/high-power field. In situ hybridization for Epstein-Barr virus encoded RNA (EBER) was negative. To our knowledge, the present case is the second case of hepatic IPT-like variant of FDCS without EBV involvement, indicating that EBV infection is not an absolute prerequisite for a diagnosis of the IPT-like variant of FDCS.

Abstract
Non-alcoholic fatty liver disease is becoming in one of the most prevalent liver diseases that leads to liver transplantation. This health problem is a multisystem disease with a complex pathogenesis that involves liver, adipose tissue, gut, and muscle. Although several pharmacological agents have been investigated to prevent or treat non-alcoholic fatty liver disease, currently there is no effective treatment for the management of this chronic liver disease. Nonetheless, the use of natural products has emerged as a alternative therapeutic for the treatment of hepatic diseases, including non-alcoholic fatty liver disease, due to its anti-inflammatory, antioxidant, antidiabetic, insulin-sensitizing, antiobesity, hypolipidemic, and hepatoprotective properties. In the present review, we have discussed the evidence from experimental and clinical studies regarding the potential beneficial effects of plant-derived natural products (quercetin, resveratrol, berberine, pomegranate, curcumin, cinnamon, green tea, coffee, garlic, ginger, ginseng, and gingko biloba) for the treatment or prevention of non-alcoholic fatty liver disease.

Abstract
BACKGROUND The incidence of metachronous multiple gastric cancer (MMGC) after gastrectomy remains unclear. This study evaluated the incidences of MMGC according to specific gastrectomy types, including pylorus-preserving gastrectomy (PPG), proximal gastrectomy (PG), and function-preserving gastrectomy (FPG), which was categorized as segmental gastrectomy and local resection. METHODS We conducted a questionnaire survey of the Japanese Society for Gastro-Surgical Pathophysiology members, who were asked to report their institutional numbers of radical gastrectomy cases for cancer between 2003 and 2012. The cases were categorized according to whether the remnant stomach's status was followed for > 5 years, confirmation of MMGC, time to diagnosis, and treatment for MMGC. We calculated the "precise incidence" of MMGC by dividing the number of MMGC cases by the number of cases in which the status of remnant stomach was followed up for > 5 years. RESULTS The responses identified 33,731 cases of gastrectomy. The precise incidences of MMGC were 2.35% after distal gastrectomy (DG), 3.01% after PPG, 6.28% after PG (p < 0.001), and 8.21% after FPG (p < 0.001). A substantial proportion of MMGCs (36.4%) was found at 5 years after the initial surgery. The rates of MMGC treatment using endoscopic submucosal dissection were 31% after DG, 28.6% after PPG, 50.8% after PG (p < 0.001), and 67.9% after FPG (p < 0.001). CONCLUSIONS The incidence of MMGC was 2.4% after DG, and higher incidences were observed for larger stomach remnants. However, the proportion of cases in which MMGC could be treated using endoscopic submucosal dissection was significantly higher after PG and FPG than after DG.

Abstract
Background and Objectives: The sensitivity of EUS-guided fine-needle biopsy (EUS-FNB) varies considerably. The optimal number of passes through a solid pancreatic lesion with a 22G FNB needle during EUS-FNB is controversial. This prospective randomized controlled study aimed to determine the optimal number of needle passes during EUS-FNB of solid pancreatic lesions, with 22G FNB needles and different sampling techniques. Methods: Pancreatic masses were sampled using 22G FNB needles with either the stylet slow-pull (SP) technique or the standard-suction (SS) technique. We determined the number of needle passes required to obtain a diagnostic accuracy of >90%. Differences between the two techniques in terms of technical success rate, cytological acquisition, core tissue acquisition, sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and complications were analyzed. Results: A total of 120 patients were randomly assigned to either SP or SS group. Three patients who were lost to follow-up and one who did not complete 5 passes due to bent needle head were excluded from the study. Fifty-six cases in the SP group and 60 cases in the SS group were included in the analysis. For SP technique, the cumulative accuracy of passes 1, 2, 3, 4, and 5 was 44.83%, 76.79%, 87.50%, 92.86%, and 94.64%, respectively. For SS technique, the cumulative accuracy of passes 1, 2, 3, 4, and 5 was 71.67%, 85.0%, 90.0%, 93.33%, and 95.0%, respectively. For each group, there was no statistically significant difference in accuracy after 3 and 4 passes. After 4 passes, the pooled sensitivity (92.59% vs. 93.10%), accuracy (92.86% vs. 93.10%), and specificity (100% vs. 100%) were similar (P > 0.05) in the SP and SS groups, respectively. In addition, positive cytological diagnoses (83.9% vs. 85.0%) and positive histological diagnoses (71.4% vs. 78.3%) were comparable (P > 0.05) in the SP and SS groups, respectively. No statistically significant factor was found associated with diagnostic sensitivity for each group. Conclusion: When on-site cytological evaluation is unavailable, we recommend that at least 3 passes with 22G ProCore needles be performed during EUS-FNB using the SS technique, at least 4 passes when using SP technique. The SS technique showed potential advantages over SP technique in tissue acquisition and diagnostic capabilities.

Abstract
According to the Developmental Origins of Health and Disease (DOHaD) hypothesis, the intrauterine environment influences fetal programming and development, affecting offspring disease susceptibility in adulthood. In recent years, therapeutic use of the Type 2 diabetes drug metformin has expanded to the treatment of pre-diabetes, polycystic ovarian syndrome, and gestational diabetes. Because metformin both undergoes renal excretion and binds to receptors on the placenta, the fetus receives equivalent maternal dosing. Although no teratogenic nor short-term harmful fetal impact of metformin is known to occur, the effects of metformin exposure on longer-range offspring development have not yet been fully elucidated. This review encapsulates the (albeit limited) existing knowledge regarding the potential longer-term impact of intrauterine metformin exposure on the development of key organs including the liver, central nervous system, heart, gut, and endocrine pancreas in animal models and humans. We discuss molecular and cellular mechanisms that would be altered in response to treatment and describe the potential consequences of these developmental changes on postnatal health. Further studies regarding the influence of metformin exposure on fetal programming and adult metabolic health will provide necessary insight to its long-term risks, benefits, and limitations in order to guide decisions for use of metformin during pregnancy.

Abstract
INTRODUCTION The global needs for a reduction in radiation exposure (RE) are increasing. Endoscopic retrograde cholangiopancreatography (ERCP) is a significant fluoroscopic procedure in the gastrointestinal field. However, the actual RE in ERCP and its annual trend are still unclear. Therefore, we examined the yearly trend of RE in ERCP. METHODS This retrospective, single-center cohort study included consecutive cases of ERCP from September 2012 to June 2019. We measured the air kerma (AK, mGy), dose area product (DAP, Gycm2), and fluoroscopy time (FT, min). We also evaluated the annual trend of the RE before and after the fluoroscopy device update. RESULTS In total, 2,174 patients receiving ERCP were enrolled. Among these, the mean age was 74.3 years, and 913 patients were women (42.0%). The median/third quartile values of AK (mGy), DAP (Gycm2), and FT (min) were 109/234 mGy, 13.3/25.8 Gycm2, and 18.2/27.7 minutes. The annual AK, DAP, and FT from 2012 to 2019 were 138, 207, 173, 177, 106, 71.0, 45.0, and 33.3 mGy; 23, 21.4, 19, 18.3, 11.9, 9.0, 6.8, and 6.4 Gycm2; and 12.5, 12.1, 9.7, 9.8, 8.2, 10.8, 9.4, and 10.3 minutes, respectively. The corresponding values before and after the update in July 2016 were 177 and 52 mGy (P < 0.0001), 19.2 and 7.6 Gycm2 (P < 0.0001), and 10.2, and 9.9 minutes (P = 0.05), respectively. DISCUSSION The RE from ERCP tended to decrease every year, especially after fluoroscopy device updates.

Abstract
South Asian (SA) Canadian immigrants have a higher risk of developing certain immune-mediated inflammatory diseases compared to non-migrant SAs. We sought to investigate the effect of migration on the gut metagenome and to identify microbiological associations between migration and conditions that may influence the development of immune-mediated inflammatory diseases. Metagenomic analysis of 58 first-generation (GEN1) SA immigrants and 38 unrelated Canadian born children-of-immigrants (GEN2) determined that the time lived in Canada was associated with continued changes in gut microbial communities. Migration of GEN1 to Canada early in life results in a gut community with similarities to GEN2 SA Canadians and non-SA North Americans. Conversely, GEN1 immigrants who arrived recently to Canada exhibited pronounced differences from GEN2, while displaying microbial similarities to a non-migrating SA cohort. Multivariate analysis identified that community composition was primarily influenced by high abundance taxa. Prevotella copri dominated in GEN1 and non-migrant SAs. Clostridia and functionally related Bacteroidia spp. replaced P. copri dominance over generations in Canada. Mutually exclusive Dialister species occurred at differing relative abundances over time and generations in Canada. This shift in species composition is accompanied by a change in genes associated with carbohydrate utilization and short-chain fatty acid production. Total energy derived from carbohydrates compared to protein consumption was significantly higher for GEN1 recent immigrants, which may influence the functional requirements of the gut community. This study demonstrates the associations between migration and the gut microbiome, which may be further associated with the altered risk of immune-mediated inflammatory diseases observed for SA Canadians.

Abstract
Background: Berberine, as an alkaloid, has a significant antitumor effect, but its mechanism in tumor metabolism, especially the Warburg effect has not been elucidated. Objectives: To study the molecular mechanism of berberine regulating the Warburg effect in ovarian cancer cells. Methods: Treatment by berberine in SKOV3 and 3AO cells or inhibited by miR-145 inhibitor transfection in berberine-treated cells to examine the changes in HK2 expression, glucose consumption and lactate production. The methylation status in the promoter region of pre-miR-145 gene was examined by bisulfite sequencing. Dual-luciferase reporter assay was conducted to verify the direct binding of miR-145 to HK2. Finally, the expression of TET3 in ovarian cancer was investigated by quantitative real-time PCR and immunohistochemistry. Results: We found berberine inhibited the Warburg effect by up-regulating miR-145, miR-145 targeted HK2 directly. Berberine increased the expression of miR-145 by promoting the expression of TET3 and reducing the methylation level of the promoter region of miR-145 precursor gene. We further found that TET3 expression was negatively correlated with clinical stage and pathological grade. Conclusions: Our results revealed berberine increased the TET3-mediated demethylation and promoted the suppression of miR-145 on HK2 to antagonize the Warburg effect of ovarian cancer cells.

Abstract
Background In China, one of the major causes of hepatic sinusoidal obstruction syndrome (HSOS) is the intake of herbals containing pyrrolizidine alkaloid (PA). However, prognostic factors for PA-induced HSOS are poorly understood. The aim of this study was to identify the independent prognostic factors for PA-induced HSOS using a multi-center study. Methods A total of 117 PA-induced HSOS patients were enrolled for data collection in three university hospitals from November 2003 to September 2018. Univariate and multivariate Cox proportional hazards analysis were used to determine prognostic factors for PA-induced HSOS. Results The median age of the PA-induced HSOS patients was 61 years (range, 21–88 years), and 64% of them were male. The survival rates at 1, 3, and 36 months were 89.71%, 72.60%, and 69.19%, respectively. Significant differences in prothrombin time (PT), international normalized ratio, total bilirubin, severity grading [new criteria for severity grading of hematopoietic stem cell transplantation (HSCT)-related HSOS in adults] were found between patients who survived and those who died. Univariate and multivariate survival analysis using Cox’s regression model demonstrated low serum albumin (<35 g/L), elevated serum urea (>8.2 mmol/L) and severe or very severe HSOS (European Society for Blood and Marrow Transplantation 2016 criteria) were independent prognostic factors of survival. Conclusions Serum albumin, serum urea, and severity grading were independent prognostic factors for patients with PA-induced HSOS, and can contribute to identifying potentially high-risk patients for early effective intervention.

Abstract
Liver transplantation is the standard treatment for children with end-stage liver disease, primary hepatic neoplasms, or liver-localized metabolic defects. Perioperative mortality is almost absent, and long-term survival exceeds 90%. Organ shortage is managed thanks to advances in organ retrieval techniques; living donation and partial liver transplantation almost eliminated waiting list mortality, thus leading to expanding indications for transplantation. The success of pediatric liver transplantation depends on the prompt and early referral of patients to transplant Centers and on the close and integrated multidisciplinary collaboration between pediatricians, hepatologists, surgeons, intensivists, oncologists, pathologists, coordinating nurses, psychologists, and social workers.

Abstract
BACKGROUND Malhi et al. in this issue critique the clinical high risk (CHR) syndrome for psychosis. METHOD Response to points of critique. RESULTS We agree that inconsistency in CHR nomenclature should be minimized. We respectfully disagree on other points. In our view: a) individuals with CHR and their families need help, using existing interventions, even though we do not yet fully understand disease mechanisms; b) substantial progress has been made in identification of biomarkers; c) symptoms used to identify CHR are specific to psychotic illnesses; d) CHR diagnosis is not "extremely difficult"; e) the pattern of progression, although heterogenous, is discernible; f) "psychosis-like symptoms" are common but are not used to identify CHR; and g) on the point described as 'the real risk,' CHR diagnosis does not frequently cause harmful stigma. DISCUSSION Malhi et al.'s arguments do not fairly characterize progress in the CHR field nor efforts to minimize stigma. That said, much work remains in areas of consistent nomenclature, mechanisms of disease, dissecting heterogeneity, and biomarkers. With regard to what the authors term the "real risk" of stigma associated with a CHR "label," however, our view is that avoiding words like "risk" and "psychosis" reinforces the stigma that both they and we mean to oppose. Moreover, patients and their families benefit from being given a term that describes what is happening to them.

Abstract
PURPOSE Lateral lymph node metastases in rectal cancer remain a clinical challenge. Different treatment regimens have been suggested. This retrospective regional cohort study examines outcome after combined oncological and surgical treatment of MRI-positive lateral lymph nodes (LLN). METHODS Data from the Swedish Colorectal Cancer Registry (SCRCR) and patient records were used for retrospective analysis of resected high-risk rectal cancers between 2009 and 2014. The aim was to compare tumour characteristics, neoadjuvant therapy, recurrence and outcome after lateral lymph node dissection. RESULTS One thousand and one hundred nineteen cases were identified and after exclusion 344 patients with cT3-T4 ≤ 10 cm from the anal verge were analysed. Thirty (8.7%) patients with MRI-positive LLN were identified. Synchronous distant metastases were associated with MRI-positive LLN (p-value 0.019). Long-course chemoradiotherapy was clinical practice in cases of MRI-positive LLN. No differences in local (p-value 0.154) or distant (p-value 0.343) recurrence rates between MRI-positive LLN patients and MRI-negative patients were detected. Only four patients underwent lateral lymph node dissection (LLND). There was no significant difference in overall survival during follow-up between the MRI-negative (CI at 95%; 99-109 months) and MRI-positive group (CI at 95%; 69-108 months; p-value 0.14). CONCLUSION Lateral lymph node metastases present a challenging clinical situation. The present study shows that combination of neoadjuvant therapy and selective LLND is an applicable strategy in cases of MRI-positive LLN.

Abstract
Liver resections are performed for acute and chronic end stage liver failure, primary and secondary liver malignancies as well as for several other neoplastic and non-neoplastic conditions. Hepatectomy specimens can be total, partial, or wedge resections. These specimens are relatively rare and complex. Meticulous handling, orientation, dissection, margin assessment, and reporting as per the latest guidelines, often require a multidisciplinary approach. This article discusses the approach to grossing of hepatectomy specimens, and the most important macroscopic considerations for specific conditions.

Abstract
Faecal microbiota transplantation (FMT) is the transfer of screened and minimally processed faecal material from a 'healthy' donor to 'diseased' recipient. It has an established role, and is recommended as a therapeutic strategy, in the management of recurrent Clostridioides difficile infection (CDI). Recognition that gut dysbiosis is associated with, and may contribute to, numerous disease states has led to interest in exploiting FMT to 'correct' this microbial imbalance. Conditions for which it is proposed to be beneficial include inflammatory bowel disease, irritable bowel syndrome, liver disease and hepatic encephalopathy, neuropsychiatric conditions such as depression and anxiety, systemic inflammatory states like sepsis, and even coronavirus disease 2019. To understand what role, if any, FMT may play in the management of these conditions, it is important to consider the potential risks and benefits of the therapy. Regardless, there are several barriers to its more widespread adoption, which include incompletely understood mechanism of action (especially outside of CDI), inability to standardise treatment, disagreement on its active ingredients and how it should be regulated, and lack of long-term outcome and safety data. Whilst the transfer of faecal material from one individual to another to treat ailments or improve health has a history dating back thousands of years, there are fewer than 10 randomised controlled trials supporting its use. Moving forward, it will be imperative to gather as much data from FMT donors and recipients over as long a timeframe as possible, and for trials to be conducted with rigorous methodology, including appropriate control groups, in order to best understand the utility of FMT for indications beyond CDI. This review discusses the history of FMT, its appreciable mechanisms of action with reference to CDI, indications for FMT with an emerging evidence base above and beyond CDI, and future perspectives on the field.

Abstract
With the morbidity and mortality associated with the COVID-19 pandemic that we are witnessing this year, the risks posed by emerging viral diseases to global health are all too obvious. This pandemic highlights the importance of antiviral drug discovery, which targets emerging viral pathogens, as well as existing pathogenic viruses that undergo continuous evolution. Drug discovery and development is a long and resource intensive process; however, the use of biomarkers can accelerate clinical development of antivirals by providing information regarding diagnosis of specific viral infections, status of infection, potential safety parameters, and antiviral responses. In clinical practice, many of the biomarkers initially utilized to support clinical development are also used for patient care. While viral load is a standard and essential biomarker used to detect the desired viral suppression induced by an antiviral agent, it has become apparent that additional biomarkers, whether related to the virus, the host or as a consequence of the drug's mechanistic effects, are also important for monitoring clinical outcomes associated with an antiviral therapy. This review summarizes the biomarkers used in the clinical development (as well as in clinical practice, where appropriate) of antiviral therapies for hepatitis C virus, hepatitis B virus, human immunodeficiency virus, and severe acute respiratory syndrome coronavirus 2.

Abstract
The aim of the study was to analyse the temporal and geographic distribution of radiologists, computed tomography and magnetic resonance scanners in Croatia. In this observational study we estimated radiologists’ number per 100,000 population for 1997, 2006, and 2017 and compared private and public CT and MR scanners between 2011 and 2018. We analyzed the availability of radiologists and scanners, and the relationship between the radiological workforce and economic strength among counties. The workforce increased significantly from 1997 to 2017 and was associated with economic strength categories in 2017. In 2018, there were more CT scanners in the public sector, while MR scanners were distributed evenly. In 2011, there was similar distribution of CT and MR between sectors, while in 2018 there were significantly more public CT scanners. Counties with a medical school had significantly more radiologists and MR scanners. The high-to-low ratios per CT and MR were 11 and 8.2, suggesting inequality of health care. Croatia significantly increased its radiological workforce; however, cross-county inequality remained. Counties with higher economic strength and medical schools have better availability of radiologists and equipment. To ensure the sustainable activity of the health care system, a precise estimate of supply and demand of radiology services is needed.

Abstract
Obesity has become a worldwide health concern among the pediatric population. The prevalence of non-alcoholic fatty liver disease (NAFLD) is growing rapidly, alongside the high prevalence of obesity. NAFLD refers to a multifactorial disorder that includes simple steatosis to non-alcoholic steatohepatitis (NASH) with or devoid of fibrosis. NAFLD is regarded as a systemic disorder that influences glucose, lipid, and energy metabolism with hepatic manifestations. A sedentary lifestyle and poor choice of food remain the major contributors to the disease. Prompt and timely diagnosis of NAFLD among overweight children is crucial to prevent the progression of the condition. Yet, there has been no approved pharmacological treatment for NAFLD in adults or children. As indicated by clinical evidence, lifestyle modification plays a vital role as a primary form of therapy for managing and treating NAFLD. Emphasis is on the significance of caloric restriction, particularly macronutrients (fats, carbohydrates, and proteins) in altering the disease consequences. A growing number of studies are now focusing on establishing a link between vitamins and NAFLD. Different types of vitamin supplements have been shown to be effective in treating NAFLD. In this review, we elaborate on the potential role of vitamin E with a high content of tocotrienol as a therapeutic alternative in treating NAFLD in obese children.

Abstract
Background Dissociation is a generally recognized phenomenon in psychology and psychiatry; however, questions are still not fully resolved about the difference between pathological and normal dissociation, as well as the role of dissociation, depending on its aetiology, in the formation of clinical manifestations of mental disorders. Objective To complement the existing data about the significance of dissociation in non-psychotic mental disorders. Design Using the Dissociative Experience Scale (DES), we screened 62 patients (13 male and 49 female) from the Non-Psychotic Conditions Inpatient Department of the Udmurt Republican Clinical Psychiatric Hospital (Izhevsk, Russia). Nineteen of the patients had mental disorders of organic aetiology and 43 patients had mental disorders of psychogenic aetiology. Results Dissociation at the pathological level was detected in 12.9% of the patients, all of them female. Among patients with psychogenic disorders, the proportion of patients with pathological dissociation was more than three times that of patients with organic disorders. Among the particular dissociative phenomena, absorption had the highest average severity, both in the general sample and in each aetiological group of patients, while dissociative amnesia had the lowest average severity. The highest levels of dissociation were found in young female patients who had never been married. In patients with psychogenic disorders, the average dissociation severity was significantly higher than in the general population, while in patients with organic disorders it was significantly lower. Conclusion The dissociation phenomenon may play a significant symptom-forming role in young women suffering from non-psychotic mental disorders of psychogenic aetiology. In the case of organic mental disorders, the severity of dissociative manifestations decreases even below the conditionally normal level, which may indirectly indicate the destruction of dissociative physiological mechanisms by an organic brain process.

Abstract
"Regular physical activity is able to replace almost every drug, but all drugs taken together will not replace exercise"
This statement was written in XVI century by Wojciech Oczko (1537-1599) royal doctor of Polish Kings. Despite medical advances over 500 years, this sentence is still relevant today. In the hundred years since the discovery of insulin, enormous progress has also been made in the pharmacological treatment of type 1 diabetes mellitus (T1DM). In the last decades new formulations of insulin, new methods of insulin delivery, e.g., advanced closed-loop hybrid systems have significantly improved glucose control. However, we must remember that good glycemic control is a key, but not one factor in preventing the development of chronic diabetes complications. Regular physical activity is associated with greater insulin sensitivity, increased fitness, better lipid profile and blood pressure [1]. It extends remission duration in children with new onset diabetes mellitus [2]. It significantly decreases risk of premature cardiovascular morbidity and all-cause mortality. Regular physical activity has not only health but also social benefits for children and adolescents with diabetes mellitus, so it is one of the fundamental parts of diabetes management and should be encouraged [3].

Abstract
We report a case of cerebral embolism caused by balloon-occluded retrograde transvenous obliteration (BRTO) for gastric varices in a 77-year-old woman with liver cirrhosis. Balloon-occluded retrograde venography demonstrated multiple collaterals between the efferent and systemic veins, and some of them could not be embolized with metallic coils. Therefore, they were embolized with ethanol, 50% glucose solution, gelatin sponge particles, and ethanolamine oleate, and BRTO was completed. After BRTO, however, the patient complained of mild aphagia and paralysis of the right fingers, and magnetic resonance imaging demonstrated cerebral embolism. The symptoms gradually improved after the administration of ozagrel sodium and rehabilitation. The varices were also completely thrombosed. Patent foramen ovale was suspected as a cause of cerebral embolism.

Abstract
The global COVID-19 pandemic has focused the attention of researchers, civil authority and the general public on the phenomenon of "panic buying," characterized by the excessive purchase of specific materials-particularly food and hygiene-related products-in anticipation of an expected shortage. This phenomenon has been well-documented in response to several natural and man-made disasters, but its global scope and severity in the context of COVID-19 are unprecedented. This response can negatively impact health, food security, and disease prevention efforts. Attempts to modify such behaviors are more likely to succeed if they are based on insights from both the biomedical and the social sciences. From a biological perspective, the phenomenological overlap between panic buying and psychological disorders such as hoarding disorder and compulsive buying raises the possibility of a shared neurobiological underpinning. Evolutionary models suggest that these behaviors represent an attempt to enhance individual and group survival in the face of a threatened scarcity of resources. These phenomena may be influenced by specific genetic variants which are also implicated in hoarding-related psychological disorders. From a psychological perspective, attachment theory provides a conceptual framework that serves as a bridge between prior life adversity, current deprivation, and an increased attachment to material objects. Such a framework is of relevance when considering panic buying during the COVID-19 pandemic, which has been associated with significant disruptions in attachment bonds. From a social-anthropological perspective, hoarding and related behaviors have been associated with social exclusion and rejection, as well a lack of social support. These risk factors have affected large sections of the general population in the context of the COVID-19 pandemic and the governmental responses to it. This perspective also emphasizes the symbolic significance of the hoarded objects themselves. In this paper, an attempt is made to integrate these three perspectives and thereby formulate a biopsychosocial model of panic buying in response to this global health crisis. The existing scientific literature on panic buying is examined in the light of this model. Finally, suggestions are proposed as to how this model might inform social strategies aimed at preventing or reducing panic buying.

Abstract
Purpose Minimally invasive gastrectomy is a promising surgical method with well-known benefits, including reduced postoperative complications. However, for total gastrectomy of gastric cancers, this approach does not significantly reduce the risk of complications. Therefore, we aimed to evaluate the incidence and risk factors for the severity of complications associated with minimally invasive total gastrectomy for gastric cancer. Materials and Methods The study included 392 consecutive patients with gastric cancer who underwent either laparoscopic or robotic total gastrectomy between 2011 and 2019. Clinicopathological and operative characteristics were assessed to determine the features related to postoperative complications after minimally invasive total gastrectomy. Binomial and multinomial logistic regression models were used to identify the risk factors for overall complications and mild and severe complications, respectively. Results Of 103 (26.3%) patients experiencing complications, 66 (16.8%) and 37 (9.4%) developed mild and severe complications, respectively. On multivariate multinomial regression analysis, independent predictors of severe complications included obesity (OR, 2.56; 95% CI, 1.02−6.43; P=0.046), advanced stage (OR, 2.90; 95% CI, 1.13−7.43; P=0.026), and more intraoperative bleeding (OR, 1.04; 95% CI, 1.02−1.06; P=0.001). Operation time was the only independent risk factor for mild complications (OR, 1.06; 95% CI, 1.001−1.13; P=0.047). Conclusions The risk factors for mild and severe complications were associated with surgery, indicating surgical difficulty. Surgeons should be aware of these potential risks that are related to the severity of complications so as to reduce surgery-related complications after minimally invasive total gastrectomy for gastric cancer.

Abstract
Objective: As targeted drugs, exogenous serpins could be introduced to patients to restore body balance. This study aimed to observe further the inhibitory effects of recombinant Hespintor (a Kazal-type serpin) combined with Sorafenib on transplanted human hepatoma tumors in nude mice specimens and to explore the possible transcriptional regulation by Hespintor. Methods: A model of human hepatoma tumors transplanted in nude mice was established, and the medication was administrated to observe the growth of the tumors. Four weeks after the drug administration, the tumors were removed to evaluate the inhibition effects of Hespintor on in-situ tumor growth and liver metastasis. The expression levels of MMP2, MMP9, Bax, Bcl-2, and caspase-3 in the tumor organizations were detected with Western blot. The target genes of the Hespintor were screened based on tissue RNA-Seq, and the regulatory network was constructed. Results: It was found that the recombinant Hespintor displayed a significant antitumor effect on the subcutaneous growth of MHCC97-H cells. Moreover, the therapeutic effects of the combination therapy were significantly better than those of single therapy. 10 target genes with significantly different expression by Hespintoron tumor tissue were identified. Finally, a visual regulatory networkwas constructed for target mRNA-pathway. Conclusions: The antitumor effect of Hespintor combined with Sorafenib in treating the subcutaneously implanted hepatocellular carcinoma tumors in nude mice was significant. The possible transcriptional regulation by Hespintor involved multiple signaling pathways, and it was not just the antitumor effect of uPA via its extracellular inhibitions.

Abstract
OBJECTIVES Autoimmune hepatitis (AIH) is a progressive liver disease managed with corticosteroids and immunosuppression and monitored using a combination of liver biochemistry and histology. However, liver biopsy is invasive with risk of pain and bleeding. The aim of the present study was to investigate the utility of noninvasive imaging with multiparametric magnetic resonance imaging (MRI) (mpMRI) to provide clinically useful information on the presence and extent of hepatic inflammation, potentially guiding immunosuppression. METHODS Eighty-one participants (aged 6-18), 21 healthy and 60 AIH patients, underwent multiparametric MRI to measure fibro-inflammation with iron-corrected T1 (cT1) at the Children's Memorial Health Institute in Warsaw alongside other clinical blood tests and liver biopsy at recruitment and after an average of 16-month follow-up (range 9-22 months). Correlation analyses were used to investigate the associations between cT1 with blood serum markers and histological scores. RESULTS At recruitment, patients with AIH had a higher cT1 value than healthy controls (P < 0.01). cT1 correlated significantly with key histopathological features of disease. Treatment naïve AIH patients showed evidence of inflammation and heterogeneity across the liver compared to healthy controls.At follow-up, cT1 showed utility in monitoring disease regression as most patients showed significantly reduced fibro-inflammation with treatment (P < 0.0001) over the observational period. Six patients had histological fibrosis and clear fibro-inflammation on MR despite biochemical remission (normalized aspartate aminotransferase (AST), alanine aminotransferase (ALT), and immunoglobulin G [IgG]). CONCLUSIONS Multiparametric MRI can measure disease burden in pediatric AIH and can show changes over time in response to therapy. Active disease can be seen even in biochemical remission in children.

Abstract
OBJECTIVE Gastric cancer patients generally have a poor outcome, particularly those with advanced-stage disease which is defined by the increased invasion of cancer locally and is associated with higher metastatic potential. This study aimed to identify genes that were functional in the most fundamental hallmark of cancer, namely invasion. We then wanted to assess their value as biomarkers of gastric cancer progression and recurrence. DESIGN Data from a cohort of patients profiled on cDNA expression arrays was interrogated using K-means analysis. This genomic approach classified the data based on patterns of gene expression allowing the identification of the genes most correlated with the invasion of GC. We evaluated the functional role of a key protein from this analysis in invasion and as a biomarker of recurrence after curative resection. RESULTS Expression of secreted frizzled-related protein 4 (SFRP4) was identified as directly proportional to gastric cancer invasion. This finding was validated in multiple, independent datasets and its functional role in invasion was also confirmed using invasion assays. A change in serum levels of SFRP4 after curative resection, when coupled with AJCC stage, can accurately predict the risk of disease recurrence after curative therapy in an assay we termed PredictR. CONCLUSIONS This simple ELISA-based assay can help predict recurrence of disease after curative gastric cancer surgery irrespective of adjuvant therapy. The results require further evaluation in a prospective trial but would help in the rational prescription of cancer therapies and surveillance to prevent under or over treatment of patients after curative resection.

Abstract
PURPOSE Liver Imaging Reporting and Data System (LI-RADS) uses multiphasic contrast-enhanced imaging for hepatocellular carcinoma (HCC) diagnosis. The goal of this feasibility study was to establish a proof-of-principle concept towards automating the application of LI-RADS, using a deep learning algorithm trained to segment the liver and delineate HCCs on MRI automatically. METHODS In this retrospective single-center study, multiphasic contrast-enhanced MRIs using T1-weighted breath-hold sequences acquired from 2010 to 2018 were used to train a deep convolutional neural network (DCNN) with a U-Net architecture. The U-Net was trained (using 70% of all data), validated (15%) and tested (15%) on 174 patients with 231 lesions. Manual 3D segmentations of the liver and HCC were ground truth. The dice similarity coefficient (DSC) was measured between manual and DCNN methods. Postprocessing using a random forest (RF) classifier employing radiomic features and thresholding (TR) of the mean neural activation was used to reduce the average false positive rate (AFPR). RESULTS 73 and 75% of HCCs were detected on validation and test sets, respectively, using > 0.2 DSC criterion between individual lesions and their corresponding segmentations. Validation set AFPRs were 2.81, 0.77, 0.85 for U-Net, U-Net + RF, and U-Net + TR, respectively. Combining both RF and TR with the U-Net improved the AFPR to 0.62 and 0.75 for the validation and test sets, respectively. Mean DSC between automatically detected lesions using the DCNN + RF + TR and corresponding manual segmentations was 0.64/0.68 (validation/test), and 0.91/0.91 for liver segmentations. CONCLUSION Our DCNN approach can segment the liver and HCCs automatically. This could enable a more workflow efficient and clinically realistic implementation of LI-RADS.

Abstract
Correlations between gut microbiota activities and inflammatory bowel disease (IBD) treatment are gaining research interest. In our previous study, Lactobacillus acidophilus KLDS 1.0901, Lactobacillus helveticus KLDS 1.8701, and Lactobacillus plantarum KLDS 1.0318 showed antibacterial, antioxidant, and immunomodulatory activities. In the current study, we evaluated the effects of three tested strains and their mixture on dextran sulfate sodium (DSS)-induced colitis in C57BL/6J mice. The three tested strains and their mixture significantly decreased the disease activity index (DAI), colon shortening, and myeloperoxidase (MPO) activity. Additionally, the three tested strains and their mixture improved the histological damage, increased the colonic mucous layer integrity, and exhibited lower levels of prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6), while up-regulating colonic anti-inflammatory cytokine IL-10 levels, tight junction proteins (E-cadherin, zonulae occludens (ZO)-1, occludin and claudin-1) and mucin (MUC1 and MUC2) mRNA expressions to some extent. In addition, mixed lactobacilli showed better anti-inflammatory effects than single-strain treatment. Our study further revealed that mixed lactobacilli increased bacterial diversity and improved gut microbiota composition, increasing short-chain fatty acid (SCFA) production. These results indicated that mixed lactobacilli supplementation could attenuate DSS-induced colitis by modulating the gut microbiota and repairing the intestinal barrier, which provided a scientific basis for its clinical application in the future.

Abstract
OBJECTIVES Comorbid of non-alcoholic fatty liver disease (NAFLD) in chronic hepatitis B (CHB) patients is common but no simple noninvasive diagnostic methods are available for the identification. This study aims to develop a noninvasive nomogram for accurate detection of NAFLD in CHB patients. PATIENTS AND METHODS This study included 535 liver biopsy-proven CHB patients with or without comorbid NAFLD. Independent risk factors of NAFLD were identified by multivariate logistic regression analysis. The risk factors identified were then incorporated into the nomogram. Performance of the nomogram was assessed by calibration, receiver operating characteristic (ROC) curve and decision curve analysis. RESULTS Of the 535 patients, 100 patients (18.69%) were diagnosed as CHB/NAFLD and 435 patients (81.31%) as simple CHB. Body mass index, serum uric acid and low-density lipoprotein cholesterol levels and diabetes mellitus were independent risk factors of NAFLD. The nomogram incorporating these 4 factors had an area under ROC curve (AUC) of 0.864, achieved good concordance index of 0.864 (95% confidence interval: 0.832-0.892) for predicting NAFLD in the patients and had well-fitted calibration curves. The nomogram had a significantly higher AUC than some previously reported models. The decision curve analysis yielded larger net benefit. CONCLUSION This study developed a simple, noninvasive, effective and convenient nomogram that achieved an optimal detection of NAFLD in CHB patients. Using this nomogram, the risk for an individual patient to have NAFLD could be discriminated, leading to a rational clinical management.

Abstract
Antimicrobial susceptibility testing (AST) for H. pylori is essential to accurately assess the prevalence of antibiotic resistance in each population. Antibiotic resistance rates form the basis of local guidelines for H. pylori treatment and AST may also be used as a personalized medicine approach to tailor therapy. This chapter provides an update on global antibiotic resistance rates and describes molecular mechanisms that confer H. pylori antibiotic resistance. An overview on the advantages and limitations of molecular AST using both invasive and noninvasive approaches is also provided.

Abstract
This is a Commentary of a review about extracellular vesicles of immune cells published two years ago in Clinical and Experimental Immunology, a prestigious journal of the field. The aim is to establish whether, and to what extent, results in scientific area of the review have been extended and strengthened by innovative findings of considerable interest. The analysis of the recently published results has revealed that in various areas of the review developments have occurred. However, innovative findings have been only about the extracellular vesicles secreted by mesenchymal stem cells, usually indicated as MSC-EVs. Based on these findings, the Commentary has been focused on recent MSC-EVs findings presented in three Sections dealing with 1. recently appeared, relevant functions of the latter vesicles; 2. therapeutic processes developed according well known criteria, however innovative in many respects; and 3. protection of COVID-19 disease patients from organ lesions induced by the specific virus, SARS-CoV-2, during the disease. As everybody knows, the COVID-19 pandemic started at the end of 2019, thus after the publication of the aforementioned review. Data of Section 3 are therefore innovative, of great potential interest also at the clinical level, applied by translational medicine to various organs, from lung to brain, heart, kidney, immune and other cells. In view of its relevance, the author expects that research and medical use of MSC-EV, active at present, will be further developed, acquiring additional relevance in the near future.

Abstract
Objectives: Due to the COVID-19 pandemic, older people are threatened, and there may be different psychological responses toward COVID-19 between women and men. The present study explored the factors and gender differences related to the fear of COVID-19 among older women and men in Taiwan. Methods: Geriatric patients (n = 139; 42 men; mean age = 71.73 years) who visited outpatient departments were recruited. They self-reported demographic data and completed questions asking about (i) their fear of COVID-19, (ii) whether they paid attention to COVID-19 news, (iii) whether searched for COVID-19 news, (iv) whether they believed in COVID-19 news, and (v) their preventive COVID-19 behaviors. Results: Both women and men reported a low fear of COVID-19, paid close attention to COVID-19 news, and practiced good preventive COVID-19 infection behaviors. The perceived chance of COVID-19 infection was a significant factor contributing to the fear of COVID-19 among both women and men. Preventive behaviors had a positive effect in lowering the fear of COVID-19. News about COVID-19 had a negative effect in lowering the fear of the disease among women but not men. Conclusions: As the performing of preventive COVID-19 infection behaviors was associated with a lower fear of COVID-19, healthcare providers should consider strategies for improving preventive behaviors among older people to help ease their worries and fears concerning COVID-19.

Abstract
BACKGROUND The aim of this study was to assess the prevalence of psychological distress and associated factors among hospitalized patients during the COVID-19 pandemic at three selected hospitals in southwest Ethiopia. METHODS An institution-based cross-sectional study design was conducted among hospitalized patients during the COVID-19 pandemic at Mizan-Tepi University Teaching Hospital, Tepi General Hospital, and Gebre Tsadik Shawo General Hospital, southwest Ethiopia from May 10 to August 10, 2020. Sample size was computed using a single-proportion formula, and systematic sampling was employed to recruit study participants. Data were collected using a structured interviewer-administered questionnaire. Psychological distress was assessed with the Kessler Psychological Distress Scale, which has been validated in Ethiopia. SPSS 21.0 was used for analysis. Descriptive statistics were calculated to characteristize the study population. Predictors of psychological distress were identified by logistic regression analyses. RESULTS Among the 337 study participants enrolled, about 41% were aged 25-34 years. The overall prevalence of psychological distress was 57.9% (95% CI 52.8%-63.5%). Being female (AOR 3.69, 95% CI 2.08-6.55), having high (AOR 5.45, 95% CI 2.35-12.66) and medium perceived life threat (AOR 3.37, 95% CI 1.75-6.48), poor (AOR 3.97, 95% CI 1.70-9.29) and moderate social support (AOR 3.17, 95% CI 1.36-7.41), and current khat use (AOR 4.16, 95% CI 1.67-10.35) were statistically associated with psychological distress during the COVID-19 pandemic at P value <0.05. CONCLUSION The prevalence of psychological distress was high among hospitalized patients during the COVID-19 pandemic. The study findings highlight the need to develop psychological support strategies to improve mental health and psychological resilience.

Abstract
Cellular senescence is a widespread cellular programme that is characterized by permanent cell cycle arrest. Senescent cells adopt a changed secretory phenotype that can alter cellular function. For years, cellular senescence has been thought to be a protective factor against cancer; however, it is now recognized that it has a dual effect on individuals. Co‐ordinated activation of cellular senescence provides advantages during embryogenesis, wound healing, tissue repair and inhibition of tumorigenesis. On the other hand, the aberrant generation and accumulation of abnormal senescent cells lead to the development of age‐related conditions and tissue deterioration. During acute kidney injury (AKI), the kidney faces multiple types of stressors and challenges, which can easily drive cellular senescence. How to appropriately progress through the cell cycle and minimize long‐term damage is of great importance to the acquisition of adaptive repair considering that no available therapeutic interventions can reliably limit injury, speedy recovery or improve the prognosis of this syndrome. Whether the manipulation of cellular senescence can become a novel therapeutic target in AKI and reignite clinical and research interest remains to be determined. Here, we share our current understanding of the role of cellular senescence in AKI, along with examples of the application of mesenchymal stem cells (MSCs) for targeting this disorder during its treatment.

Abstract
BACKGROUND Bronchiolitis obliterans is a fatal respiratory disease characterized by the obliteration of small airways. Mesenchymal stem cells (MSCs) is a promising candidate for cell-based therapy. OBJECTIVE To evaluate the therapeutic effect of human umbilical cord-derived mesenchymal stem cells (HUC-MSCs) on a murine model of bronchiolitis obliterans like injury (BOLI). METHOD The murine model of BOLI was established by administrating of diacetyl (DA) via intratracheal instillation. Treatment of HUC-MSCs or HUC-MSCs culture medium (HUC-MSCs-CM) was conducted in the BOLI model. RESULTS The pathogenic manifestations, lung function, and the number of neutrophils were similar between the oropharyngeal inhalation DA group (OPI-DA), intratracheal instillation group (ITI-DA); however, less reduction of weight and higher survival rate were observed in ITI-DA groups. Compared with the control groups, the trend of weight loss was significantly reduced (p < .05), and the pulmonary function was significantly improved (p < .05) in HUC-MSCs and HUC-MSCs-CM groups. Masson staining and hematoxylin and eosin staining showed that the deposition of collagen around bronchioles and blood vessels is less and airway epithelial cells and basal cells in lung tissue repaired better in HUC-MSCs and HUC-MSCs-CM groups compared with the control groups. Immunofluorescence shows the expression of E-cadherin and cytokeratin 5 (CK-5) were significantly higher in HUC-MSCs and HUC-MSCs-CM groups compared with control groups, while HUC-MSCs themselves did not express E-cadherin or CK-5. The DiI label showed HUC-MSCs gradually reduced after 2 days in the bronchus and 4 days in bronchiole. CONCLUSION HUC-MSCs could help to repair airway epithelial cells in a murine model of BOLI. It might be related to paracrine factors of HUC-MSCs.

Abstract
In recent clinical practice the molecular diagnostics have been significantly empowered and upgraded by the use of Artificial Intelligence and its assisted technologies. The use of Machine leaning and Deep Learning Neural network architectures have brought in a new dimension in clinical oncological research and development. These algorithm based software system with enhanced digital image analysis have emerged into a new branch of digital pathology and contributed immensely towards precision medicine and personal diagnostics. In India, gastric cancer is one of the most common cancers in males as well as in females. Various molecular biomarkers are associated with gastric cancer development and progression of which HER2 protein, a transmembrane tyrosine kinase (TK) receptor of epidermal growth factor receptors (EGFRs) family is of prime importance. The EGF receptor expression in gastric cancer is linked with its prognostics and theragnostics. These expressions are assessed by immunohistochemistry (IHC) and molecular techniques such as Fluorescence in-situ hybridization (FISH), as per recommendations for HER2 targeted immunotherapy. These have motivated the software giants like Google Inc. to produce innovative state of art technologies mimicking human traits such as learning and problem solving skill sets. This field is still under development and is slowly evolving and capturing global importance in recent times. A literature search on PubMed was performed to access updated information for this manuscript.

Abstract
This article explores the role of ApoA4 in a CCl4-induced chronic liver injury (CLI) mouse model. C57BL/6J mice (WT) and ApoA4 knock-out (KO) mice were divided into CCl4 CLI (WT-CCl4 and KO-CCl4) and olive oil solvent control groups (WT-Veh and KO-Veh). Some of the KO-CCl4 mice were additionally treated with recombinant mouse ApoA4 and primary mouse T lymphocyte injections. After 6 weeks, histological analyses, biochemical and superoxide dismutase (SOD) and malondialdehyde (MDA) assays, flow cytometry of immune cells and qRT-PCR analyses were performed. KO mice after treatment with CCl4 showed reduced hepatic SOD and enhanced serum MDA activities leading to worsening liver injury and fibrosis compared with WT-CCl4, accompanied by enhanced hepatic alpha smooth muscle actin (α-SMA), tissue inhibitor of metalloproteinases-1 (TIMP-1) and collagen type I alpha 1 chain (COL1A1) transcriptions, elevated macrophage M1 levels, enhanced tumor necrosis factor-alpha (TNF-α), Interleukin 6 (IL-6) and C-C Motif Chemokine Ligand 5 (CCL5), but reduced Interleukin 10 (IL-10), monocyte chemotactic protein 1 (MCP-1), C-C Motif Chemokine Receptor 2 (CCR2), C-X3-C Motif Chemokine Receptor 1 (CX3CR1) and C-X-C Motif Chemokine Ligand 9 (CXCL9) transcription, as well as reduced CD3+, CD4+ and CD8+ T cell percentages in hepatic tissue, blood cells and spleen. In addition, CD11b+CD115+, CD11b+/Ly6Chigh, CD11b+/LyC6- and CD11b+/Ly6Cint cells were enhanced, which partly reversed by ApoA4 protein and T cell injections. In conclusion, we propose that ApoA4 might be involved in liver protection via inhibiting fibrotic mediators and inflammatory cytokines, suppression of pro-inflammatory hepatic M1 cell invasion and regulation of CD8+ T and CD4+ T lymphocytes.
