Abstract
Background Increasing clarithromycin resistance has led to the need for an alternative first-line therapy for the eradication of Helicobacter pylori (H. pylori) in Korea, and bismuth containing quadruple therapy (BQT) and tailored therapy (TT) have been proposed as alternative regimens. The aim of this study was to compare the eradication rates of BQT and TT as first-line H. pylori eradication therapies. Methods H. pylori infection was diagnosed using the rapid urease test or dual-priming oligonucleotide-based multiplex polymerase chain reaction (DPO-PCR) during endoscopy. Patients positive for H. pylori were divided into two groups; those tested using the rapid urease test received empirical BQT (the BQT group) whereas those tested by DPO-PCR received TT (the TT group). Eradication rates, adverse events, and overall medical costs, which included diagnostic test and eradication regimen costs, were compared. Results Three hundred and sixty patients were included in the study (TT group 178, BQT group 182). The modified intention-to-treat eradication rates of BQT and TT were 88.2% (142/161) and 80.3% (118/147), respectively (p=0.055), and corresponding eradication rates in the per-protocol population were 88.8% (142/160) and 81.4% (118/145) (p=0.07). Compliance and adverse event rates were similar in the two groups. Average medical costs were $ 90.3 per patient in the TT group and $ 75.5 in the BQT group (p=0.000). Conclusions Empirical BQT and tailored therapy were similar in terms of H. pylori eradication rate, safety, and tolerability, but BQT was more cost-effective.

Abstract
Background
Phloem-feeding insects are known to modulate the salicylic acid (SA) signaling pathway in various plant-insect interaction models. Diaphorina citri is a phloem feeding vector of the deadly phytopathogens, Candidatus Liberibacter americanus and Candidatus Liberibacter asiaticus, and the interactions of D. citri with its host that may modulate plant defenses are not well understood. The objectives of this study were to investigate the molecular mechanisms involved in transcriptional regulation of SA modification and activation of defense-associated responses in sweet orange (Citrus sinensis) exposed to various durations (7-, 14- and 150- days) of continuous feeding by D. citri.
Results
We quantified expression of genes involved in SA pathway activation and subsequent modification, as well as, associated SA metabolites (SA methyl ester, 2,3-Dihydroxybenzoic acid and SA 2-O-β-D-glucoside). NPR1 and PR-1 expression was upregulated in plants exposed to continuous feeding by D. citri for 14 days. Expression of BSMT-like, MES1-like and DMR6-like oxygenase, as well as, accumulation of their respective SA metabolites (SA methyl ester, 2,3-Dihydroxybenzoic acid) was significantly higher in plants exposed to continuous feeding by D. citri for 150 days than in those without D. citri infestation. Concomitantly, expression of UGT74F2-like was significantly downregulated and its metabolite, salicylic acid 2-β-D-glucoside, was highly accumulated in trees exposed to 150 d of feeding compared to control trees without D. citri.
Conclusions
D. citri herbivory differentially regulated transcription and SA-metabolite accumulation in citrus leaves, depending on duration of insect feeding. Our results suggest that prolonged and uninterrupted exposure (150 d) of citrus to D. citri feeding suppressed plant immunity and inhibited growth, which may highlight the importance of vector suppression as part of huanglongbing (HLB) management in citrus.

Abstract
Background: Micro-computerized tomography (micro-CT) is considered as an innovative non-invasive and high-resolution imaging technology. The current research aims to reconstruct the distribution of preputial vessels in different severity of rat congenital hypospadias model by micro-CT, and to provide an anatomic basis for the selection of preputial vessel pedicle flaps in surgery.
Methods: Pregnant rats were exposed to finasteride from gestational day 12 to 17. Depending on the position of the urethral meatus, the pups were divided into normal, mild hypospadias and severe hypospadias groups. Six months after birth, the preputial blood vessels were observed in vascular perfusion with Microfil (a silicone-based polymer) and scanned by micro-CT. CTvox and NRecon were utilized to reconstruct 3-dimentional(3D) images. A pathological analysis of the specimen was taken in order to determine the position of Microfil.
Results: The normal group and the mild hypospadias group had similar preputial image characteristics. At the junction of the inner and outer prepuce, the deep layer vessels of the superficial fascia were transversely distributed and formed a vascular ring-like structure. Among the severe hypospadias group, five had sufficient blood circulation while six had insufficient blood circulation. In sufficient blood circulation type, the ring-like vessels were found at the junction of the inner and outer prepuce similar to that of the normal and mild hypospadias group. However, only a small amount of capillary supply to this area in the insufficient type.
Conclusion: The junction of the inner and outer prepuce with abundant blood circulation was suitable to be a vascular pedicle flap. The tubularized preputial island flaps were consistent with the ring-like vessels area, and the original blood supply was retained to the greatest extent.

Abstract
Background: Suicidal ideation and attempts are highly prevalent among medical students compared to the general population and negatively impacts the quality of life, physical, and mental well being of students. However, research into suicidal ideation and attempts among medical students in low and middle-income countries are limited. Therefore, this study aimed to explore the suicidal ideation and attempts and associated factors among medical students in Ethiopia.
Methods : An institution based cross-sectional study was conducted on 393 medical students from March to June 2019 at the University of Gondar in Ethiopia. A simple random sampling technique used to get study units by their identification card. Suicidal ideation and attempts were assessed by using World Health Organization Composite International Diagnostic Interview (CIDI) to assess lifetime suicidal ideation and attempt during medical school. Data were collected using self-administered questionnaires. Bi-variable and multivariable logistic regression analyses were used to identify associated factors between suicidal ideation and attempts with the explanatory variables at P-value <0.05 was considered statistically significant.
Results: A total of 393 study participants were interviewed with a response rate of 92.9%. The prevalence of suicidal ideation and attempts among study participants were found to be 14% and 7.4% with 95% CI (10.9, 18.1) and (5.1, 10.2), respectively. In multivariate logistic regression; female sex (AOR: 5.21, 95% CI: 2.42, 11.20), depression (AOR: 10.12, 95% CI; 4.80, 21.52), current khat chewing (AOR: 4.46, 95% CI; 132, 15.02), and poor social support (AOR: 4.46, 95% CI: 1.43, 13.87) were factors significantly associated with suicidal ideation. Being female (AOR: 8.08, 95% CI: 3.04, 21.39), depression (AOR: 10.66, 95% CI; 4.01, 28.01 ), and history of mental illness (AOR: 5.53, 95% CI; 1.20, 25.50) were factors significantly associated with suicide attempts.
Conclusions : In the current study, the prevalence of suicidal ideation among medical students was low compared to other studies, but the suicide attempt was high. Ethiopian medical students better to instate a screening program for every medical student for early detection and intervention of suicidal ideation and attempt.

Abstract
Objectives: The study was carried out to optimize the phenotypic method to characterize the sickle cell trait (SCT), sickle cell anaemia (SCA) and β-thalassemia (β-TT) suspected sample from tharu community of South Western province-5, Nepal. SCT and SCA were further evaluated by genotypic method employing amplification refractory mutation system (ARMS PCR). Moreover, Glucose 6 Phosphate Dehydrogenase (G6PD) was estimated in those hemoglobinopathy to observe its prevalence. The accurate and reliable method can play an important role in reduction of morbidity and mortality rate.
Results: The 100 suspected cases were subjected to phenotypic method adopting cellulose acetate electrophoresis and genotypic metod using ARMS PCR which portraits (5%) SCA positive test showing HBS/HBS, (38%) SCT positive trait HBA/HBS and (36%) cases normal HBA/HBA. β-TT (21%) cases were confirmed by electropherogram. G6PD deficiency was observed in (40%) of SCA, (18.4%) of SCT, (4.8%) of β-TT and (2.8%) in normal cases. Increased G6PD were developed only in SCT (5.3 %) and β-TT (4.8%). The study highlighted sickle cell disorder (SCD) and β-TT as the most common hemoglobinopathy coexisting with G6PD deficiency. Though hemoglobinopathy sometime could be protective in malaria but G6PD deficiency can cause massive hemolysis which may exacerbate the condition.

Published: October 2019

Abstract
Background
Acute appendicitis (AA) is the most common surgical condition in children. Although a higher incidence of AA in summer has been reported, the reason for this observation remains unclear. The purpose of this study was to compare the clinical findings of AA patients who underwent appendectomies during the summer months with those who underwent the procedure during the non-summer months.
Methods
The clinical data of 171 patients who underwent appendectomy from January 2013 to December 2016 were reviewed. The patients were divided into a summer group (from May to October) and a non-summer group (from November to April) based on the month when appendectomy was performed. All patients were under 18 years of age at the time of surgery. Laboratory data, computed tomography scans, pathology reports and operative records were reviewed.
Results
The number of patients with AA was higher in the summer group than in the non-summer group (101 vs. 70 patients). No significant differences in the laboratory results between the two groups of patients were observed. The percentage of AA patients who presented with a fecalith was significantly lower in the summer group (33.6%) than in the non-summer group (55.7%). No significant differences in the incidence of appendiceal perforations and abscesses were observed between the two groups.
Conclusions
The percentage of AA patients with fecaliths in summer was lower than that in the non-summer months. The increase in the number of AA patients in summer may be due to the increased occurrence of lymphoid hyperplasia, which may be correlated with the yearly outbreak of enterovirus infection during this period.

Published: October 2019

Abstract
Background More and more studies demonstrated that genetic variation at C1GALT1 influences Gd-IgA1 level in IgAN. However, whether the expression of β1, 3-galactosyltransferase (β1, 3Gal-T) was influenced may provide insights into how Gd-IgA1 levels are controlled in IgAN. Methods Thirty IgAN patients diagnosed in Tianjin Medical University General Hospital from April to September 2018 and 30 healthy volunteers whose age and gender matched with patients were enrolled in this study. Total Gd-IgA1 levels in plasma were determined by ELISA and C1GALT1 levels were determined by RT-PCR. Four databases (PubMed, EMBASE, CNKI, WanFang Medical Network) were searched to identify eligible studies that evaluated a difference in the expression of C1GALT1 in IgAN patients compared with total controls (non-IgAN and health controls). The C1GALT1C1 expression levels, which was indispensable to β1, 3Gal-T of IgA1, was also been compared. Results Gd-IgA1 levels were remarkable higher in IgAN patients compared with healthy control. The expression levels of C1GALT1 gene were remarkably down-regulated in IgAN patients compared with healthy control. And the mRNA level of C1GALT1 was inversely correlated to Gd-IgA1 levels. In meta-analysis, six articles including 316 participants that analyzed the expression of β1, 3Gal-T were met inclusion criteria. There was no significant difference in the expression of C1GALT1 between IgAN patients compared with controls. And we found patients with IgAN had lower levels of C1GALT1 gene expression in the B cells compared to controls. The C1GALT1C1 levels in the IgAN patients were not different from the levels in the control group, which were unchanged no matter according to different ethnic population, different control group and different cell source. Two studies including 46 persons compared enzymatic activity of β1, 3Gal-T in B cells, and the result showed the β1, 3Gal-T activity was decreased in B cells. Conclusions We found expression levels of C1GALT1 were remarkably downregulated in IgAN patients and negatively correlated with higher levels of Gd-IgA1. Subsequent meta-analysis validated the low expression and activity of β1, 3Gal-T in B cells in patients with IgAN. However, there was no apparent disparity in the aspect of C1GALT1C1 expression between IgAN and control groups.

Abstract
Background Sexually transmissible infection (STI) and blood-borne virus (BBV) notification data is a mainstay of the Australian National Notifiable Diseases Surveillance System (NNDSS) and is a mandatory requirement in all Australian jurisdictions. The system focuses on STI and BBV diagnoses alone, without testing, treatment or management data, leaving major gaps in the understanding of epidemics, especially among priority populations like Aboriginal and Torres Strait Islander peoples. Further information is required to supplement the NNDSS to better understand epidemics, the impact of interventions and health care delivery against clinical guidelines. Here we describe the rationale, processes and expected outcomes of establishing a national STI and BBV sentinel surveillance network in Aboriginal primary care services—known as the ATLAS network.Methods Researchers invited participation and consultation with Aboriginal Community-Controlled Health Services (ACCHS) clustered in five clinical hubs across four jurisdictions, representative of urban, regional and remote regions. Site-specific participation agreements were developed for each clinical hub and individual ACCHS. De-identified electronic medical record (EMR) data relating to STI and BBV testing, treatment and care are collected passively from each health service via the GRHANITE tm data extraction tool. These data are analysed centrally to inform 12 performance indicators which are included in surveillance reports generated for each health service and clinical hub.Results The ATLAS network currently involves 29 ACCHS representing all five clinical hubs. The ATLAS network provides detailed surveillance reports to individual ACCHS as well as contributing to aggregate comparative analyses at the clinical hub, jurisdictional and national levels. Data derived from the ATLAS network is used to assess clinical practice within each site. Aggregated data will inform clinical guidelines and extend the research potential of participating ACCHS sites. The ATLAS infrastructure can be expanded to include other health services and potentially linked to other data sources using GRHANITE.Conclusions The ATLAS network will supplement the NNDSS and contribute to improved understanding of local, regional and national patterns of clinical care of STI and BBV to inform clinical practice, policy, and program-planning.

Abstract
Background Sweden has nearly 300 youth clinics that have been offering services since the 1970s. However, no evaluation has been done to assess their youth-friendliness. This study aims to assess: i) to what extent youth clinics are perceived as youth-friendly by the young people using them; and ii) if the level of youth friendliness is equally perceived across different sociodemographic groups of users.Methods The four northernmost counties of Sweden were included in the study. Of the total identified 22 youth clinics, 20 participated by giving out questionnaires to the youth after their visits to the respective youth clinics. In total 1,110 youth participated in the study and answered questions according to the World Health Organization’s criteria of accessibility, equity, respect, privacy and confidentiality, no judgement, and quality. Means and frequencies were calculated, and t-test and ANOVA were used to compare means by sociodemographic variables.Results Participants perceived the youth clinics as very youth friendly across the measured domains, with scores as high as 4.8 and 4.9 (of a maximum of 5) in the studied domains. Youth clinics were perceived in a similar way regardless of gender, but other sociodemographic factors influenced some of the domains, especially ethnic background.Conclusions The perception of youth friendliness in youth clinics was very high. Nonetheless, younger users; users who did not categorize themselves as either heterosexual, homosexual, or bisexual; users with trans-experiences; and users with migrant backgrounds gave youth clinics lower scores for certain domains.

Abstract
The current diagnostic methods and treatments still fail to lower the incidence of anthracycline-induced cardiotoxicity effectively. In this study, we aimed to (1) analyze the cardiotoxicity-related genes after breast cancer chemotherapy in gene expression database and (2) carry out bioinformatic analysis to identify cardiotoxicity-related abnormal expressions, the biomarkers of such abnormal expressions, and the key regulatory pathways after breast cancer chemotherapy. Cardiotoxicity-related gene expression data (GSE40447) after breast cancer chemotherapy was acquired from the GEO database. The biomarker expression data of women with chemotherapy-induced cardiotoxicity (group A), chemotherapy history but no cardiotoxicity (group B), and confirmatory diagnosis of breast cancer but normal ejection fraction before chemotherapy (group C) were analyzed to obtain the mRNA with differential expressions and predict the miRNAs regulating the differential expressions. The miRanda formula and functional enrichment analysis were used to screen abnormal miRNAs. Then, the gene ontology (GO) analysis was adapted to further screen the miRNAs related to cardiotoxicity after breast cancer chemotherapy. The data of differential analysis of biomarker expression of groups A, B, and C using the GSE40447-related gene expression profile database showed that there were 30 intersection genes. The differentially expressed mRNAs were predicted using the miRanda and TargetScan software, and a total of 2978 miRNAs were obtained by taking the intersections. Further, the GO analysis and targeted regulatory relationship between miRNA and target genes were used to establish miRNA-gene interaction network to screen and obtain 7 cardiotoxicity-related miRNAs with relatively high centrality, including hsa-miR-4638-3p, hsa-miR-5096, hsa-miR-4763-5p, hsa-miR-1273g-3p, hsa-miR6192, hsa-miR-4726-5p and hsa-miR-1273a. Among them, hsa-miR-4638-3p and hsa-miR-1273g-3p had the highest centrality. The PCR verification results were consistent with those of the chip data. There are differentially expressed miRNAs in the peripheral blood of breast cancer patients with anthracycline cardiotoxicity. Among them, hsa-miR-4638-3p and hsa-miR-1273g-3p are closely associated with the onset of anthracycline cardiotoxicity in patients with breast cancer. Mining, integrating, and validating effective information resources of biological gene chips can provide a new direction for further studies on the molecular mechanism of anthracycline cardiotoxicity.
