Abstract
The coronavirus disease 2019 (COVID-19) pandemic has caused changes in the global health system, causing significant setbacks in healthcare systems worldwide. This pandemic has also shown resilience, flexibility, and creativity in reacting to the tragedy. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection targets most of the respiratory tract, resulting in a severe sickness called acute respiratory distress syndrome that may be fatal in some individuals. Although the lung is the primary organ targeted by COVID-19 viruses, the clinical aspect of the disease is varied and ranges from asymptomatic to respiratory failure. However, due to an unorganized immune response and several affected mechanisms, the liver may also experience liver cell injury, ischemic liver dysfunction, and drug-induced liver injury, which can result in respiratory failure because of the immune system’s disordered response and other compromised processes that can end in multisystem organ failure. Patients with liver cirrhosis or those who have impaired immune systems may be more likely than other groups to experience worse results from the SARS-CoV-2 infection. We thus intend to examine the pathogenesis, current therapy, and consequences of liver damage concerning COVID-19.

Abstract
OBJECTIVES The purpose of this study is to analyze the relationship between the occurrence of the National Brain Injury Awareness Week and public interest in the concussion topic in Australia through an analysis of Internet search activity data from Google Trends. STUDY DESIGN Online retrospective observational study. METHODS For the keyword "concussion", the search interest rate over a period of 10 years between August 2012 and August 2022 within Australia has been analyzed using the Google Trends tool. The rising related topics that contributed to the months with the highest search interest were extracted for each year and a trendline analysis was performed to capture temporal patterns. RESULTS There was a significant difference in the average search interest between the month of August, when the Brain Injury Awareness Week is annually held, and the rest of the year (d = 0.09, p = 0.017). Also, May and August were the two months with the overall highest search interests (mean ± SD: 73.3 ± 5.16 and mean ± SD: 70.1 ± 5.49, respectively). Trendline analysis showed a positive slope of 0.3081 with R2 = 0.4462 for search interests of concussion over the 10-year period. CONCLUSIONS The data suggest that there is a growing interest and potential awareness of concussion in Australia that seems highly limited to the context of sports such as football, rugby, and soccer. Major sports events, news coverage, and media exposure appear to be associated with this trend. The study highlights the importance of more investment in producing engaging media content to educate the public on concussion of different causes and improving strategies for National Brain Injury Awareness Week.

Abstract
Antibiotics are recognized widely for their benefits when used appropriately. However, they are often used inappropriately despite the importance of responsible use within good clinical practice. Effective antibiotic treatment is an essential component of universal healthcare, and it is a global responsibility to ensure appropriate use. Currently, pharmaceutical companies have little incentive to develop new antibiotics due to scientific, regulatory, and financial barriers, further emphasizing the importance of appropriate antibiotic use. To address this issue, the Global Alliance for Infections in Surgery established an international multidisciplinary task force of 295 experts from 115 countries with different backgrounds. The task force developed a position statement called WARNING (Worldwide Antimicrobial Resistance National/International Network Group) aimed at raising awareness of antimicrobial resistance and improving antibiotic prescribing practices worldwide. The statement outlined is 10 axioms, or "golden rules," for the appropriate use of antibiotics that all healthcare workers should consistently adhere in clinical practice.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) is a significant human pathogen that is responsible for a variety of illnesses, including mucosa-associated lymphoid tissue lymphoma, gastric cancer, peptic ulcers, and gastritis.
AIM To investigate the frequency of H. pylori infection and its resistance patterns among Egyptian patients and to determine the influence of H. pylori virulence genetic determinants on the eradication success of 14-d triple therapy regimen.
METHODS H. pylori infections were investigated in 72 patients with gastroduodenal complications suggestive of H. pylori infection. The cagA and vacA genotypes of cultured strains were studied using polymerase chain reaction. The patients underwent 14 d of triple-therapy treatment. The treatment response was examined using histology and a rapid urease test 6 wk after therapy discontinuation.
RESULTS The intention-to-treat eradication rate was 59.2% (95%CI: 48.2%–70.3%). Rates of H. pylori resistance to clarithromycin, amoxicillin, and metronidazole were 52.8%, 81.9%, and 100%, respectively. Successful eradication of H. pylori was more significantly associated with vacA s1-positive strains [adjusted odds ratio (aOR) = 0.507, 95%CI: 0.175–0.822]. A significant association was found between failed eradication rate and H. pylori strains resistant to clarithromycin (aOR = 0.204, 95%CI: –0.005 to 0.412) and amoxicillin (aOR = 0.223, 95%CI: 0.026–0.537).
CONCLUSION This study’s low H. pylori eradication rate following 14-d triple therapy is concerning and worrying. H. pylori pan-resistance to metronidazole followed by the high resistance to ciprofloxacin, amoxicillin, and clarithromycin in this research is challenging and of great concern.

Abstract
The cross-section area is a crucial parameter to assess peripheral neuropathy. The ultrasonographic evaluation of cross-section area of median nerve is a low-cost and readily available tool for diagnosis and assessment. However, the intra-nerve dimensional variability and its normative reference value in a healthy subject are missing. The current meta-analysis aims to capture the median nerve cross-section area for healthy subjects and generate a comprehensive ultrasonographic reference data set for each population. METHODS The full text of manuscripts were collected after short-listing the abstracts collected from search strategy. A quality assurance tool was used to capture the risk of bias of each study after reviewing the included manuscripts. The pooled estimate of cross-section area was stratified according to anatomical landmarks, sex, and ancestry. RESULTS A total of 97 observational studies dealt with 6679 wrists of healthy subjects were included. The pooled estimate of the cross-section area of median nerve at carpal tunnel inlet was 8.54mm2 [95% CI: 8.34-8.74mm2]. The same pooled estimate at carpal tunnel outlet was 8.03mm2 [95% CI: 7.46-8.60mm2]. Both these pooled estimates have significant correlation with mean age of population. Age and sex were two primary predictors of the cross-section of median nerve. The flattening ratio, circularity, and wrist-forearm ratio of median nerve were also computed. CONCLUSION These normative data could serve as a reference for assessing median nerve pathologies, including carpal tunnel syndrome. The ethnic variation of pooled estimate and heterogeneity will guide clinician set up the reference value for diagnostic criteria.

Abstract
Abstract
Introduction/Objective
Nodular fasciitis is a rapidly growing but benign self-limited myofibroblastic/fibroblastic tumor of unknown etiology. It was first described in the literature by Konwaler in 1955 and can occur in any location. Nodular fasciitis of the tongue is a rare entity in infancy with only one case reported so far. Accurate diagnosis of this entity is crucial to avoid a possible misdiagnosis of malignancy leading to radical resections.
Methods/Case Report
A 6-month old, previously heathy full term male presented to pediatric otolaryngology clinic with a rapidly growing painless mass on the right tongue. The mass was associated with feeding difficulty. There was no history of trauma to the area, no personal and family history of cancer was noted. Computed tomography scan demonstrated a 1.5 x 1.4 x 1.5 cm mass confined to the right anterior undersurface of tongue. Biopsy of the mass showed ulcerated mucosa with an underlying spindle cell lesion composed of reactive-appearing myofibroblasts arranged in a variably fascicular to "tissue-culture" pattern, intermixed with inflammatory cells and scattered extravasated erythrocytes. These morphologic features in conjunction with immunohistochemistry and demonstration of fusion of SRSF3 [serine and arginine rich splicing factor 3] and USP6 [ubiquitin specific peptidase 6] by Targeted next-generation RNA sequencing confirmed the diagnosis of nodular fasciitis. On follow up, spontaneous regression of the mass occurred in 3 months.
Results (if a Case Study enter NA)
NA.
Conclusion
Nodular fasciitis of tongue in infancy is an exceedingly rare entity and this case demonstrates the importance of including this unique entity in the differential diagnosis of a rapidly-growing tongue lesion. Because it can simulate malignancy both clinically and histologically, awareness and familiarity with this benign proliferative lesion is crucial in effective management.

Abstract
Despite the recent decrease in overall prevalence of Helicobacter pylori infection, morbidity and mortality rates associated with gastric cancer remain high. The antimicrobial resistance developments and treatment failure are fueling the global burden of H. pylori-associated gastric complications. Accurate diagnosis remains the opening move for treatment and eradication of infections caused by microorganisms. Although several reports have been published on diagnostic approaches for H. pylori infection, most lack the data regarding diagnosis from a clinical perspective. Therefore, we provide an intensive, comprehensive, and updated description of the currently available diagnostic methods that can help clinicians, infection diagnosis professionals, and H. pylori researchers working on infection epidemiology to broaden their understanding and to select appropriate diagnostic methods. We also emphasize appropriate diagnostic approaches based on clinical settings (either clinical diagnosis or mass screening), patient factors (either age or other predisposing factors), and clinical factors (either upper gastrointestinal bleeding or partial gastrectomy) and appropriate methods to be considered for evaluating eradication efficacy. Furthermore, to cope with the increasing trend of antimicrobial resistance, a better understanding of its emergence and current diagnostic approaches for resistance detection remain inevitable.

Abstract
BackgroundInterstitial lung diseases (ILD) are a diverse group of pulmonary diseases for which accurate diagnosis is critical for optimal management and outcomes. Diagnosing ILD, both idiopathic pulmonary fibrosis (IPF) and connective-tissue-disease-associated interstitial lung disease (CTD-ILD), has become critically important, as the disease has a devastating prognosis with poor survival.There are also management implications, as patients with ILD can now potentially be treated with new antifibrotic therapies such as pirfenidone and nintedanib, both of which have been approved. Certain types of CTD – ILD may benefit from systemic immunomodulatory therapies. Diagnosis of ILD can be challenging and a multidisciplinary team (MDT) approach is recommended in current guidelines. Several studies have reported that MDT diagnosis is associated with higher levels of diagnostic confidence and better interobserver agreement (1-3).ObjectivesWe describe the benefits of an ILD multidisciplinary service on the diagnosis and management of patients with suspected ILD.MethodsWe performed a single-centre retrospective review of consecutive patients referred to the ILD clinic with subsequent discussions in ILD MDTs over a 36-month period from 2016 to 2019. We compared changes in ILD diagnosis and management at referral to those following the ILD-MDT. We collected data on the demographics, occupation, age at ILD onset, smoking status, imaging, blood tests including autoimmune serology, MDT recommendations, change in diagnosis after MDT, tertiary referral, serial PFTs, medications and outcomes. Cases of suspected ILD that were not fully characterised and those with complex management issues were presented at our monthly ILD MDT.ResultsA total of 208 patients were referred to the ILD clinic over a 36-month period. Of these, 106 cases were discussed at the ILD MDT and the remaining 102 cases did not require discussion at the MDT as these deemed to be clear cut, which included RA and CTD ILD. The mean age of the total cohort was 74 (min age 32, max age 97) and 120 (58 %) were males. Overall, evaluation by the ILD service (i.e. ILD clinic and MDT) resulted in a change in diagnosis in 106(51%) patients. Of those, 49(46%) didn’t have ILD. In the remaining 57 patients with suspected ILD, the majority of the diagnoses were ILD with an uncertain classification (24, 23%). The other diagnoses included CTD-ILD (4, 3.7%), ILD with autoimmune serology 11(10.4%), IPF 10(9.4%), Drug-induced-ILD 3(2.8%), Hypersensitivity Pneumonitis 5(4.7%), Eosinophilic pneumonitis 1 (0.94%), Cryptogenic Pneumonitis 1(0.94%), PPFE with IPF 1 (0.94%), PPFE 1 (0.94%), CPFE 4 (0.94%), EAA 2 (0.94%), RB-ILD 2 (1.88%), Langerhans Histiocytosis 2 (1.88%).16/57(28%) were referred to a tertiary centre for further management. Serology was positive in 11 patients (ANA 6, CCP 3, and ANCA 2). Of the 57 patients with other diagnoses, the main recommendations included steroids (28), anti-fibrotic therapy (4), immunomodulatory therapy (6) and ambulatory Oxygen (1). Further analysis will be carried out on survival and treatment outcomes of the cohort.ConclusionDedicated ILD-MDT service has an important clinical impact on the care of the ILD patient, with frequent changes in ILD diagnosis and subsequent management and outcomes. Multidisciplinary approach to the management of these patients should be standard of care for these patients.References[1]Flaherty KR, King TE Jr, Raghu G, et al.

Abstract
Helicobacter pylori colonize the gastric mucosa of at least half of the world’s population. Persistent infection is associated with the development of gastritis, peptic ulcer disease, and an increased risk of gastric cancer and gastric-mucosa-associated lymphoid tissue (MALT) lymphoma. In vivo studies using several animal models have provided crucial evidence for understanding the pathophysiology of H. pylori-associated complications. Numerous animal models, such as Mongolian gerbils, transgenic mouse models, guinea pigs, and other animals, including non-human primates, are being widely used due to their persistent association in causing gastric complications. However, finding suitable animal models for in vivo experimentation to understand the pathophysiology of gastric cancer and MALT lymphoma is a complicated task. In this review, we summarized the most appropriate and latest information in the scientific literature to understand the role and importance of H. pylori infection animal models.

Background
There has been a proliferation of machine learning (ML) electrocardiogram (ECG) classification algorithms reaching >85% accuracy for various cardiac pathologies. Despite the high accuracy at individual institutions, challenges remain with cross-institutional algorithm evaluation. Transfer learning (TL) is a technique in which a model trained for a specific task is repurposed for another related task, in this case ECG ML model trained at one institution used to classify ECGs at another institution. Models trained at one institution, however, might not be generalizable for accurate classification when deployed broadly due to differences in type, time, and sampling rate of traditional ECG acquisition. TL would thus require additional ECG signal processing which inherently introduces noise and has high computational costs. Our previous work has shown that frequency domain (FD) convolutional neural networks (CNN) outperform traditional time domain (TD) CNN methods in detecting atrial fibrillation (Afib) and are more robust against noise and sampling variations.
Purpose
In this study, we explore ECG transfer learning by comparing performance of TD and FD CNN ECG classification models. Examine the hypothesis that FD signal analysis can overcome limitations inherent to TD and demonstrate application for Afib classification in three different publicly available datasets.
Methods
PTB-XL ECG dataset was used to train TD and FD CNN models for Afib classification. TL on the two data sets, Lobachevsky University Electrocardiography Database (LUDB) and KURIAS-ECG database (KURIAS), was performed with portions of each dataset added to PTB-XL training data before test runs on the remaining ECGs. The models were also tested directly on the two datasets (cross-testing) for comparison.
Results
Results of TL are summarized in Fig. 1. Panels (a) and (b) show TD and FD performance on PTB-XL dataset, with FD outperforming TD. Panels (c) and (d) show TL of PTB-XL trained TD and FD models applied on LUDB Afib data with FD outperforming TD. Panels (e) and (f) show TL of PTB-XL trained models applied to KURIAS Afib ECGs, with FD again outperforming TD. Table 1 summarizes results of TL and direct cross-testing with TL outperforming cross-testing.
Conclusions
FD models were superior to TD models in Afib classification, both in cross-testing and TL. TL technique, in which a pre-trained model is used as starting point for novel dataset training, outperformed direct cross-testing. TL with FD CNN has the capacity to leverage models trained on a particular set of ECGs to classify ECGs with varying signal acquisition properties. FD CNN may be robust to inter-institutional variability and has potential for widespread application with no compromise to ECG classification power. A potential application of these findings is deployment of ECG classification CNN models trained at institutions with large ECG databases to hospitals with smaller datasets.

Abstract
BACKGROUND The objectives of the study were to investigate the organizational characteristics of acute care facilities worldwide in preventing and managing infections in surgery; assess participants' perception regarding infection prevention and control (IPC) measures, antibiotic prescribing practices, and source control; describe awareness about the global burden of antimicrobial resistance (AMR) and IPC measures; and determine the role of the Coronavirus Disease 2019 pandemic on said awareness. METHODS A cross-sectional web-based survey was conducted contacting 1432 health care workers (HCWs) belonging to a mailing list provided by the Global Alliance for Infections in Surgery. The self-administered questionnaire was developed by a multidisciplinary team. The survey was open from May 22, 2021, and June 22, 2021. Three reminders were sent, after 7, 14, and 21 days. RESULTS Three hundred four respondents from 72 countries returned a questionnaire, with an overall response rate of 21.2%. Respectively, 90.4% and 68.8% of participants stated their hospital had a multidisciplinary IPC team or a multidisciplinary antimicrobial stewardship team. Local protocols for antimicrobial therapy of surgical infections and protocols for surgical antibiotic prophylaxis were present in 76.6% and 90.8% of hospitals, respectively. In 23.4% and 24.0% of hospitals no surveillance systems for surgical site infections and no monitoring systems of used antimicrobials were implemented. Patient and family involvement in IPC management was considered to be slightly or not important in their hospital by the majority of respondents (65.1%). Awareness of the global burden of AMR among HCWs was considered very important or important by 54.6% of participants. The COVID-19 pandemic was considered by 80.3% of respondents as a very important or important factor in raising HCWs awareness of the IPC programs in their hospital. Based on the survey results, the authors developed 15 statements for several questions regarding the prevention and management of infections in surgery. The statements may be the starting point for designing future evidence-based recommendations. CONCLUSION Adequacy of prevention and management of infections in acute care facilities depends on HCWs behaviours and on the organizational characteristics of acute health care facilities to support best practices and promote behavioural change. Patient involvement in the implementation of IPC is still little considered. A debate on how operationalising a fundamental change to IPC, from being solely the HCWs responsibility to one that involves a collaborative relationship between HCWs and patients, should be opened.

Abstract
Transport disturbs birds' welfare and health status which lead to oxidative stress and dietary ascorbic acid mitigates the adverse effects of transport stress. The present study was aimed to evaluate the impacts of ascorbic acid administration on oxidative stress indices, cortisol, H/L ratio, tonic immobility reaction and rectal temperature of pigeons exposed to road transport. A total of 80 clinically healthy pigeons were selected and randomly divided to eight equal groups as follow: (1) Ctrl- : fed by basal diet and no subjected to transport stress; (2) Ctrl+: fed by the basal diet and subjected to transport stress; (3, 4) 1DBS10 and 1DBS16: received ascorbic acid from 1 day before transport stress at doses of 10 g/100 L and 16 g/100 L of drinking water, respectively; (5, 6) 3DBS10 and 3DBS16: treated with ascorbic acid from 3 consecutive days before transport stress at doses of 10 g/100 L and 16 g/100 L, respectively and (7, 8) 7DBS10 and 7DBS16: received ascorbic acid from 7 consecutive days before the transport at doses 10 g/100 L and 16 g/100 L, respectively. Birds were transported for 3 h over a distance of about 200 km. The total antioxidant capacity, malondialdehyde and cortisol were measured before transport and at 6, 24 and 72 h post-transportation. The rectal temperature and tunic immobility reactions were recorded. Dietary ascorbic acid led to a decrease in tonic immobility response, hetrophil to lymphocyte ratio, circulating cortisol and total antioxidant capacity, and an increase in circulating malondialdehyde in pigeons exposed to transport stress compare to Ctrl+ group. In conclusion, ascorbic acid administration at dose 16 g/100 L of drinking water from 3 and 7 days before exposure to stress helps attenuate undesirable effects of oxidative stress in pigeons.

Abstract
Osseointegration of dental, craniofacial, and orthopedic implants is critical for their long-term success. Multifunctional surface treatment of implants was found to significantly improve cell adhesion and induce osteogenic differentiation of dental-derived stem cells in vitro. Moreover, local and sustained release of antibiotics via nanolayers from the surface of implants can present unparalleled therapeutic benefits in implant dentistry. Here, we present a layer-by-layer surface treatment of titanium implants capable of incorporating BMP-2-mimicking short peptides and gentamicin to improve their osseointegration and antibacterial features. Additionally, instead of conventional surface treatments, we employed polydopamine coating before layer-by-layer assembly to initiate the formation of the nanolayers on rough titanium surfaces. Cytocompatibility analysis demonstrated that modifying the titanium implant surface with layer-by-layer assembly did not have adverse effects on cellular viability. The implemented nanoscale coating provided sustained release of osteoinductive peptides with an antibacterial drug. The surface-functionalized implants showed successful osteogenic differentiation of periodontal ligament stem cells and antimicrobial activity in vitro and increased osseointegration in a rodent animal model 4 wk postsurgery as compared with untreated implants. Altogether, our in vitro and in vivo studies suggest that this approach can be extended to other dental and orthopedic implants since this surface functionalization showed improved osseointegration and an enhanced success rate.

Abstract
BACKGROUND AND AIM To determine the application range of diagnostic kits utilizing anti-Helicobacter pylori antibody, we tested a newly developed latex aggregation turbidity assay (latex) and a conventional enzyme-linked immunosorbent assay (E-plate), both containing Japanese H. pylori protein lysates as antigens, using sera from seven Asian countries. METHODS Serum samples (1797) were obtained, and standard H. pylori infection status and atrophy status were determined by culture and histology (immunohistochemistry) using gastric biopsy samples from the same individuals. The two tests (enzyme-linked immunosorbent assay and latex) were applied, and receiver operating characteristics analysis was performed. RESULTS Area under the curve (AUC) from the receiver operating characteristic of E-plate and latex curves were almost the same and the highest in Vietnam. The latex AUC was slightly lower than the E-plate AUC in other countries, and the difference became statistically significant in Myanmar and then Bangladesh as the lowest. To consider past infection cases, atrophy was additionally evaluated. Most of the AUCs decreased using this atrophy-evaluated status; however, the difference between the two kits was not significant in each country, but the latex AUC was better using all samples. Practical cut-off values were 3.0 U/mL in the E-test and 3.5 U/mL in the latex test, to avoid missing gastric cancer patients to the greatest extent possible. CONCLUSIONS The kits were applicable in all countries, but new kits using regional H. pylori strains are recommended for Myanmar and Bangladesh. Use of a cut-off value lower than the best cut-off value is essential for screening gastric cancer patients.

Abstract
The use of serum anti-Helicobacter pylori IgG and pepsinogen (PG) detection as a diagnostic method was evaluated in Sri Lanka. Gastric biopsies were performed (353 patients), and the prevalence of H. pylori infection was 1.7% (culture) and 2.0% (histology). IgG serology testing showed an area under the curve (AUC) of 0.922 (cut-off, 2.95 U/mL; specificity, 91.56%; sensitivity, 88.89%). Histological evaluation showed mild atrophy (34.3%), moderate atrophy (1.7%), metaplasia (1.7%), chronic gastritis (6.2%), and normal tissue (56%). The PGI/PGII ratio was significantly higher in H. pylori-negative patients (p < 0.01). PGII and PGI/PGII levels were lower in patients with metaplasia than in those with normal mucosa (p = 0.049 and p < 0.001, respectively). The PGI/PGII ratio best discriminated metaplasia and moderate atrophy (AUC 0.88 and 0.76, respectively). PGI and PGII alone showed poor discriminative ability, especially in mild atrophy (0.55 and 0.53, respectively) and chronic gastritis (0.55 and 0.53, respectively). The best cut-off to discriminate metaplasia was 3.25 U/mL (95.19% specificity, 83.33% sensitivity). Anti-H. pylori IgG and PG assessment (ABC method) was performed (group B, 2.0%; group A, 92.1%). The new cut-off more accurately identified patients with metaplasia requiring follow-up (group B, 5.4%). Assessment of anti-H. pylori IgG and PG is valuable in countries with a low prevalence of H. pylori infection.

Abstract
The COVID-19 pandemic presents a serious public health challenge in all countries. However, repercussions of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections on future global health are still being investigated, including the pandemic’s potential effect on the emergence and spread of global antimicrobial resistance (AMR). Critically ill COVID-19 patients may develop severe complications, which may predispose patients to infection with nosocomial bacterial and/or fungal pathogens, requiring the extensive use of antibiotics. However, antibiotics may also be inappropriately used in milder cases of COVID-19 infection. Further, concerns such as increased biocide use, antimicrobial stewardship/infection control, AMR awareness, the need for diagnostics (including rapid and point-of-care diagnostics) and the usefulness of vaccination could all be components shaping the influence of the COVID-19 pandemic. In this publication, the authors present a brief overview of the COVID-19 pandemic and associated issues that could influence the pandemic’s effect on global AMR.

Abstract
Objective This cross-sectional study aims to determine the prevalence and associated risk factors of biofilm-producing A. baumannii nosocomial isolates from a tertiary care hospital, as well as to investigate any possible association of biofilm formation with the distribution of biofilm-related genotypes and antibiotic resistance phenotypes. Methods A total of 94 non-duplicate A. baumannii nosocomial isolates were identified, their biofilm formation was quantitatively detected using the modified microtiter plate assay, and their susceptibilities to different antibiotics were determined using the breakpoint method. Isolates were then subjected to PCR assays targeting bap, ompA and bla PER-1 genes. Results The majority (70.1%) of isolates were biofilm producers. The most prevalent biofilm gene was ompA (63.8%), followed by bap (13.8%) and bla PER-1 (10.6%). The presence of multi- and extensive-drug resistance (MDR and XDR) was significantly associated with biofilm producers (p = 0.017 and 0.002, respectively). The length of hospital stay (aOR= 0.023), the presence of ompA gene (aOR = 0.286) or bap gene (aOR = 0.346), ampicillin/sulbactam resistance (aOR = 1), and the presence of MDR (aOR = -0.329) or XDR (aOR = -0.252) were considered significant risk factors associated with biofilm-producing isolates. Conclusion The high prevalence of biofilm-producing MDR and XDR nosocomial isolates in this study is worrisome and alarming. Characterization of risk factors could help control the continuous selection and transfer of this serious A. baumannii phenotype inside hospitals and improve the quality of patients' care.

Abstract
Successful tissue engineering therapies rely on the appropriate selection of the cell source, biomaterial, and regulatory factors. To be applied in a wide range of clinical applications, the ideal cell source needs to be easily accessible and abundant. Human orofacial tissues and teeth harbor several populations of mesenchymal stem cells (MSCs) with self-renewal and multilineage differentiation capabilities. The ease of access, relative abundance, and minimally invasive isolation procedures needed to harvest most types of the dental-derived MSCs render them a promising cell source for tissue engineering applications. A growing body of evidence has reported the profound immunoregulatory potential of dental-derived MSCs as compared with their bone marrow counterparts. Biomaterials can act as a physical barrier protecting the MSCs from the invasion of the immune system by hindering penetration of proinflammatory cells/cytokines, leading to higher viability of the encapsulated MSCs and improved tissue regeneration. Besides their protective capabilities, biomaterials can actively contribute to the immunoregulatory potential of the MSCs through their physical and chemical properties, including porosity and elasticity. However, despite recent advancement, the therapeutic capability of biomaterials to regulate the MSC-host immune system crosstalk and the mechanism underlying this immunoregulation has been poorly understood. It has been reported that biomaterials can regulate the viability and determine the fate of the encapsulated MSCs through modulation of the NF-kB pathway and the caspase-3 and caspase-8 proapoptotic cascades. Additionally, the physiomechanical properties of the encapsulating biomaterial have been shown to modulate clustering of TNF-α receptors on the encapsulated MSCs while regulating the production of anti-inflammatory factors such as indoleamine 2,3-dioxygenase (IDO) and prostaglandin E2 (PGE2) through activation of the P38 MAPK pathway. In the current review, we sought to provide a thorough overview of the immunomodulatory functions of dental-derived MSCs and the role of biomaterials in their interplay with the host immune system.

Abstract
The β decay of ^{208}Hg into the one-proton hole, one neutron-particle _{81}^{208}Tl_{127} nucleus was investigated at CERN-ISOLDE. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N>126, Z<82 quadrant of neutron-rich nuclei. While both negative and positive parity states with spin 0 and 1 are expected within the Q_{β} window, only three negative parity states are populated directly in the β decay. The data provide a unique test of the competition between allowed Gamow-Teller and Fermi, and first-forbidden β decays, essential for the understanding of the nucleosynthesis of heavy nuclei in the rapid neutron capture process. Furthermore, the observation of the parity changing 0^{+}→0^{-}β decay where the daughter state is core excited is unique, and can provide information on mesonic corrections of effective operators.

Abstract
Iron plays important roles in healthy brain but altered homeostasis and concentration have been correlated to aging and neurodegenerative diseases. Iron enters the central nervous system by crossing the brain barrier systems: the Blood- Brain Barrier separating blood and brain and the Blood-Cerebrospinal Fluid Barrier (BCSFB) between blood and CSF, which is in contact with the brain by far less selective barriers. Herein, we develop a two-compartmental model for the BCSFB, based on first-order ordinary differential equations, performing numerical simulations and sensitivity analysis. Furthermore, as input parameters of the model, experimental data from patients affected by Alzheimer's disease, frontotemporal dementia, mild cognitive impairment and matched neurological controls were used, with the aim of investigating the differences between physiological and pathological conditions in the regulation of iron passage between blood and CSF which can be possibly targeted by therapy.

Abstract
Helicobacter pylori causes persistent infection in the gastric epithelium of more than half of the world’s population, leading to the development of severe complications such as peptic ulcer diseases, gastric cancer, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Several virulence factors, including cytotoxin-associated gene A (CagA), which is translocated into the gastric epithelium via the type 4 secretory system (T4SS), have been indicated to play a vital role in disease development. Although infection with strains harboring the East Asian type of CagA possessing the EPIYA-A, -B, and -D sequences has been found to potentiate cell proliferation and disease pathogenicity, the exact mechanism of CagA involvement in disease severity still remains to be elucidated. Therefore, we discuss the possible role of CagA in gastric pathogenicity.

Abstract
Introduction Helicobacter pylori causes, via the influence of several virulence factors, persistent infection of the stomach, which leads to severe complications. Vacuolating cytotoxin A (VacA) is observed in almost all clinical strains of H. pylori; however, only some strains produce the toxigenic and pathogenic VacA, which is influenced by the gene sequence variations. VacA exerts its action by causing cell vacuolation and apoptosis. We performed a PubMed search to review the latest literatures published in English language. Areas covered Articles regarding H. pylori VacA and its genotypes, architecture, internalization, and role in gastric infection and pathogenicity are reviewed. We included the search for recently published literature until January 2020. Expert opinion H. pylori VacA plays a crucial role in severe gastric pathogenicity. In addition, VacA mediated in vivo bacterial survival leads to persistent infection and an enhanced bacterial evasion from the action of antibiotics and the innate host defense system, which leads to drug evasion. VacA as a co-stimulator for the CagA phosphorylation may exert a synergistic effect playing an important role in the CagA-mediated pathogenicity.

Abstract
Periconceptional folic acid is known to have a major role in the prevention of neural tube defects, leading to global recommendations for folic acid supplementation before and in early pregnancy. Maternal folate throughout pregnancy may have other roles in offspring health, including neurodevelopment and cognitive performance in childhood. Folate and folic acid (vitamin B9) act as a co-enzyme essential for single carbon metabolism, a network of pathways involved in several biological processes including nucleotide synthesis, DNA repair, and methylation reactions. In general, rapidly growing and multiplying cells require an adequate supply of folate. A primary deficiency of natural folate resulting in an increase of the total homocysteine concentration may be detrimental to the quality of the oocyte, subsequent fertilisation, embryogenesis, implantation, and fetal development. However, to date, folate-methionine metabolism and folate transport have not been studied in developing buffalo embryos. The present study details transcript expression for genes encoding key enzymes in the linked folate-methionine cycles in the ovary tissue, cumulus cells, immature oocytes, IVM oocytes, and pre-implantation embryos and also estimates the folate concentration in follicular fluid (FF) of buffalo. The FF was pooled and collected by aspiration of different sizes of surface follicles (2-8mm diameter). The total number of analysed samples was three, with different dilutions and estimation of folate in FF of buffalo done by chemiluminescence assay. Total RNA was extracted from oocytes, cumulus cells, ovarian tissue, and embryos produced from IVF. RT-PCR was performed to analyse the expression of folate-methionine cycle enzymes and folate transporters. Transcripts for all the enzymes of the folate-methionine cycle (i.e. SHMT, MTR, MTRR, MAT1A, MAT2B, GNMT, AHCY, CBS, and DHFR) and folate transporters (FOLR1, FOLR2) and reduced folate carrier (SLC19A1) were expressed in ovarian tissue, cumulus cells, oocytes, and pre-implantation embryos. Immunocytochemical analysis revealed FOLR2 and SLC19A1 protein expression on the plasma membrane and/or cytoplasm of the oocytes and embryos, and FOLR1 in the nucleus of pre-implantation embryos. The folate concentration in FF was 24ngmL−1. This is the first report to examine the concentration of folate in FF and revealed the identification of transcripts in different samples of buffalo species. The presence of these enzymes could have a profound effect on single-carbon metabolism within the ovary and pre-implantation embryo, therefore indicating that folate from FF is being disseminated through folate receptors within oocytes and embryos to participate in the folate pathway. This study advocates the necessity for examination of the result of folate supplementation throughout invitro embryo production for improving the quality and quantity of transferable blastocysts and subsequently live calf births in buffalo.

Abstract
The present study was carried out to isolate mesenchymal stem cells (MSCs) from adipose tissue of cattle (Bos indicus), characterise them, and apply them for the treatment of mastitis and metritis in the cow. Cattle MSCs were isolated from adipose tissue near the loin region of cow. Isolated adipose tissue was subjected to enzymatic digestion using 2% collagenase with agitation at regular intervals. The cells obtained after digestion were resuspended in cell culture flasks containing growth enriched medium and cultured under standard culture conditions. Alkaline phosphatase staining was used as one of the parameters to confirm cultured putative MSCs. Bovine Ad-MSCs were further characterised using real time-PCR by amplification of MSC-specific markers: CD73, CD90, and CD105 as positive markers and CD34, CD45, and CD79a as negative markers. Immunocytochemistry showed the presence of CD73, CD90, and CD105 on the cell surface. Three groups-control (C), local (L), and intravenous (IV)-with 6 cows suffering from mastitis were taken in each group and subjected to MSC transplantation through local and intravenous routes. Control group animals were subjected to antibiotic treatment only. Similarly, another three groups were taken with 6 cows in each group suffering from metritis. Post-transplantation wound healing, tissue repair, and reduction in inflammation were monitored for 26 days, at different time intervals; that is, after Days 1, 3, 7, and 15. Blood samples were also collected from animals at the same time intervals for real time-PCR. A similar examination was also done in metritis groups along with the analysis of the reduction in turbidity of cervical fluid at the abovementioned time intervals. Real time-PCR was performed to determine relative expression of genes for proliferative factors, anti-inflammatory cytokines, and antimicrobial peptides on cells isolated from blood collected at different time intervals. Gene expression in the local group of mastitis subjected to MSC injection was significantly higher than that of the IV and control group. The somatic cell count declined in both local and IV groups compared with the control group. Whereas the expression of the same genes in the IV group of metritis was significantly higher than that of the local and control groups of cows. The turbidity of cervical fluid and mucus was reduced in the IV group compared with the local group. In conclusion, we demonstrated the healing potential of MSCs in a cow model via MSC injection. Promising results were obtained in curing mastitis in both local and IV groups, whereas healing in the case of metritis was significantly higher in the IV group compared with both the control and local groups of cows. The study indicates the potential use of MSc for treatment of mastitis and metritis in cattle through wound healing and decreasing microbial infection.

Abstract
Onychomycosis is considered a fungal nail infection caused mainly by dermatophytes, yeasts and non-dermatophyte molds including dematiaceous fungi. Onychomycosis caused by non-dermatophyte molds is a health problem in the medical environment as the patients frequently return to outpatient clinics seeking new therapeutic modalities. Here, we report the first case of onychomycosis caused by a black fungus, Neoscytalidium novaehollandiae, in the right hand finger nail of a 52-year-old Iranian female with no history of immunodeficiency and underlying disease. The pattern of nail involvement was recognized as total dystrophic onychomycosis. Examination of nail scrapings with potassium hydroxide revealed brown, septate and branching sub-hyaline to dark-colored hyphae. The black fungus isolated in culture was identified as Neoscytalidium novaehollandiae by molecular analysis. The patient received oral terbinafine plus ciclopirox nail lacquer twice a week and began responding to the treatment three months after initial antifungal therapy. Additional four weeks' use of terbinafine plus ciclopirox nail lacquer completely resolved the clinical manifestations of onychomycosis. After four months, both microscopy and culture were negative.

Abstract
BACKGROUND Helicobacter pylori CagA has been found to be immuno-dominant protein and utilized for the diagnosis of the infection with cagA-positive strains. It is important to characterize the peptide epitopes capable of detecting serum anti-CagA antibodies to understand CagA immunogenicity. METHODS Sera from 171 Japanese patients were subjected for the epitope mapping study. Eighty seven peptides were designed from the CagA consensus sequence and were used for ELISA protocol to test the serum samples. The reacting anti-CagA IgG amounts to specific peptides were measured and compared. RESULTS The study revealed a strong reactivity of two peptides (c7-NNTEPIYAQVNKKKAGQAT and c8-AGQATSPEEPIYAQVAKKV) in H. pylori-infected group. Interestingly, these two peptides contained the well-known EPIYA-A and EPIYA-B region, respectively, which are two out of three CagA phosphorylation domains. Tyrosine-phosphorylation of these peptides reduced their reactivity in most sera. Moreover, additional peptides' mapping and chimeric-peptides' experiments indicated that the amino acids (QV and KK) accommodated in right-side flanking regions of both EPIYA-motifs were essential for their strong reactivity, whereas the third EPIYA-motif containing peptide (c12-GRSASPEPIYATIDFDEA) with differing flanking amino acids was not reactive in most cases. CONCLUSIONS Our results suggest that the amino acid sequences constituted in the two reactive peptides are the important immunogenic regions of CagA which would be useful to develop next-generation peptide-based diagnostic assays.

Abstract
Helicobacter pylori colonizes the gastric epithelial cells of at least half of the world's population, and it is the strongest risk factor for developing gastric complications like chronic gastritis, ulcer diseases, and gastric cancer. To successfully colonize and establish a persistent infection, the bacteria must overcome harsh gastric conditions. H. pylori has a well-developed mechanism by which it can survive in a very acidic niche. Despite bacterial factors, gastric environmental factors and host genetic constituents together play a co-operative role for gastric pathogenicity. The virulence factors include bacterial colonization factors BabA, SabA, OipA, and HopQ, and the virulence factors necessary for gastric pathogenicity include the effector proteins like CagA, VacA, HtrA, and the outer membrane vesicles. Bacterial factors are considered more important. Here, we summarize the recent information to better understand several bacterial virulence factors and their role in the pathogenic mechanism.

Abstract
Staphylococcus aureus normally colonizes the nasal cavity and pharynx. After breaching the normal habitat, the organism is able to cause a number of infections at any site of the body. The development of antibiotic resistance has created a global challenge for treating infections. Therefore, protection by vaccines may provide valuable measures. Currently, several vaccine candidates have been prepared which are either in preclinical phase or in early clinical phase, whereas several candidates have failed to show a protective efficacy in human subjects. Approaches have also been made in the development of monoclonal or polyclonal antibodies for passive immunization to protect from S. aureus infections. Therefore, in this review we have summarized the findings of recently published scientific literature to make a concise report.

Abstract
BACKGROUND Birds are considered as a reservoir for pathogenic and non-pathogenic fungi. Pigeon droppings have the potential for spreading these fungi to the environment. Cryptococcus species are important fungi associated with pigeon droppings. In this regard, there are many types of yeast associated with guano that is important for human and animal health. AIMS The main objective of this study is the identification of non-Cryptococcus yeasts isolated from pigeon dropping in Shiraz, Southern Iran. METHODS A total of 100 unknown yeasts, which were previously screened and identified as non-Cryptococcus from pigeon guano through the conventional methods, were used in this study. Identification of the isolates was performed based on conventional methods and DNA sequence analysis of internal transcribed spacer (ITS) rDNA gene region. The sequence results were deposited in NCBI database using the Basic Local Alignment Search Tool (BLAST). RESULTS A total of 16 species belonging to 7 genera were identified as Candida spp. 51% (8 species), Rhodotorula sp. 24%, Trichosporon spp. 21% (3 species), Rhodosporidium 2%, Saccharomyces 1%, Rhizoctonia 1%, and Meyerozyma 1%. The predominant isolates were Rhodotorula rubra (24%), Candida famata (20%), and Trichosporon asahii (13%). The other species were Rhodosporidium kratochvilovae 2 (2%), Saccharomyces cerevisiae 1 (1%), Rhizoctonia solani 1 (1%), and Meyerozyma caribbica 1 (1%). CONCLUSION Pigeon excreta examined in this study were associated with several kinds of opportunistic yeasts which could cause diseases in prone human and animals.

Abstract
OBJECTIVE Cryptococcosis is a major opportunistic fungal infection caused by members of the genus Cryptococcus, mainly those belonging to the Cryptococcus neoformans/Cryptococcus gattii species complexes. Here, we report a comprehensive molecular epidemiological study of the environmental distribution of Cryptococcus isolates in Shiraz, Iran with review of litreature. METHOD A total of 406 samples were obtained from Eucalyptus trees and 139 samples from pigeon droppings. Cryptococcus species identification and genotyping were performed by amplified fragment length polymorphism (AFLP) fingerprinting sequencing and sequencing of the ITS rDNA region. RESULTS Majority of the isolates belonged to the Naganishia taxon (n=69) including N. albida (formerly C. albidus, n=62), N. globosa (formerly C. saitoi, n=4), N. adeliensis (formerly C. adeliensis, n=2), N. diffluens (formerly C. diffluens, n=1), and the identified C. neoformans isolates (n=25) belonged to genotype AFLP1/VNI (n=22) and AFLP1B/VNII (n=3). CONCLUSION More research efforts should be employed to isolate C. gattii species complex from environmental niches in Iran and provide additional evidence related to novel molecular types.

Abstract
Gastric cancer is the third leading cause of cancer-related deaths and ranks as the fifth most common cancer worldwide. Incidence and mortality differ depending on the geographical region and gastric cancer ranks first in East Asian countries. Although genetic factors, gastric environment, and Helicobacter pylori infection have been associated with the pathogenicity and development of intestinal-type gastric cancer that follows the Correa’s cascade, the pathogenicity of diffuse-type gastric cancer remains mostly unknown and undefined. However, genetic abnormalities in the cell adherence factors, such as E-cadherin and cellular activities that cause impaired cell integrity and physiology, have been documented as contributing factors. In recent years, H. pylori infection has been also associated with the development of diffuse-type gastric cancer. Therefore, in this report, we discuss the host factors as well as the bacterial factors that have been reported as associated factors contributing to the development of diffuse-type gastric cancer.

Abstract
In addition to its role in gastric conditions,
Helicobacter pylori has been found to contribute to the development of several non-gastric issues in recent years. Eradication therapy is the only effective management strategy to minimize the
H. pylori-related gastric cancer and extra-gastric complications. For an effective “test and treat” strategy, diagnosis and therapy are both important. Because the infection is usually asymptomatic, patient selection is a critical issue for timely diagnosis and many clinical and demographic factors should be considered. Clarithromycin and metronidazole resistance rates also need to be considered while eradication therapy is offered. In this report, we discuss the issues which must be taken into account for the correct and timely diagnosis and for the antibiotic therapy-based management of
H. pylori infection.

Abstract
Lifetimes of excited states of the 98;100;102Zr nuclei were measured by using the Generalized Centroid Difference Method. The nuclei of interest were populated via neutron-induced fission of 241Pu and 235U during the EXILL-FATIMA campaign. The obtained lifetimes were used to calculate the B(E2) transition strengths and β deformation parameters which were then compared with the recent theoretical predictions obtained with Monte Carlo Shell Model.

Abstract
BACKGROUND Helicobacter pylori BabA is an important outer membrane protein that involves in the attachment to the gastric mucosa and enhances the virulence property of the bacterium. This study was aimed to characterize the bab genotypes, to evaluate its association with cagA, vacA and clinical diseases as well as degree of gastric inflammation. METHODS H. pylori isolates from four countries were subjected for the characterization of bab. The locus specific forward and bab specific reverse primers were used to get the specific products by PCR, which could distinguish the three locus (A, B and C). The histological activities were evaluated according to the Updated Sydney system. RESULT In patients from high risk countries (Bhutan and Myanmar) relatively higher frequencies of strains with babA-positivity (91.8% and 90.7%, respectively), babA at locus A (98% and 91.2%, respectively) and with single babA (96.8% and 91.2%, respectively) were found. Strains with two loci occupied were the most prevalent in Bhutan (84.6%), Myanmar (74.7%), Nepal (58.3%) and Bangladesh (56.9%). The genotype babA at locus A/babB at locus B/bab-negative at locus C (babA/babB/-) was the most common genotype isolated from Bhutan (82.7%), Myanmar (58.7%), Nepal (32%) and Bangladesh (31.4%) among all genotypes assessed. This genotype was also associated with the peptic ulcer disease (P = 0.013) when compared to gastritis. babA-positive characteristics and the genotype babA/babB/- exhibited the enhanced histological activities. CONCLUSIONS The higher prevalence of virulence associated babA-positive characteristics and enhanced histological activities in Bhutan than in Myanmar, Nepal and Bangladesh might partly explain why the peoples in Bhutan are at higher risk for developing severe gastric complications.

Abstract
INTRODUCTION Respiratory tract infections are one of the most common human infections in all age group and important cause of mortality and morbidity worldwide. Most bacterial upper respiratory tract infections are vaccine preventable. This study aimed to determine the prevalence of carrier state of bacterial upper respiratory tract pathogens among school children. It also aimed to study their antibiograms. METHODS The specimen from posterior pharyngeal wall and tonsils were collected from 204 participants on calcium alginate coated swabs (HiMedia). Isolates were identified by standard microbiological methods and tested for in vitro antibiotic susceptibility testing by modified Kirby-Bauer disc diffusion method. RESULTS In this study, Streptococcus pneumoniae (16.6%) was the most common bacterial pathogen recovered, followed by Staphylococcus aureus (14.7%), β-haemolytic streptococci (non-Group A) (8.8%), Streptococcus pyogenes (5.3%) and Corynebacterium diphtheriae (3.4%). The Gram negative bacteria were Klebsiella pneumoniae (4.9%), Haemophilus influenzae (3.4%) and Neisseria meningitidis (1.4%). Important findings in antibiogram include high resistance of Streptococcus pneumoniae to penicillin (91.17%) and resistance of S. aureus to oxacillin (23.3%). CONCLUSION Pharyngeal colonisation by S. pneumoniae was found high among school children and this calls for an urgent need to include pneumococcal vaccine in routine national immunisation schedule of Nepal given the high burden of invasive pneumococcal disease. Despite expected universal vaccination, pharyngeal colonisation by C. diphtheriae is possible and there is possibility of transmission of these respiratory pathogens to other healthy children.
