ABSTRACT
Background: Acute pancreatitis (AP) has a high incidence, and patients can develop recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) after AP. Objectives: We aimed to estimate the pooled incidence rates (IRs), cumulative incidences, and proportions of RAP and CP after AP. Design: A systematic review and meta-analysis of studies reporting the proportion of RAP and CP after AP. Data sources and methods: The systematic search was conducted in three (PubMed, EMBASE, and CENTRAL) databases on 19 December 2023. Articles reporting the proportion of RAP or CP in patients after the first and multiple episodes of AP were eligible. The random effects model was used to calculate the pooled IR with 95% confidence intervals (CIs). The I 2 value assessed heterogeneity. The risk of bias assessment was conducted with the Joanna Briggs Institute Critical Appraisal Tool. Results: We included 119 articles in the quantitative synthesis and 29 in the IRs calculations. Our results showed that the IR of RAP in adult patients after AP was 5.26 per 100 person-years (CI: 3.99-6.94; I 2 = 93%), while in children, it was 4.64 per 100 person-years (CI: 2.73-7.87; I 2 = 88%). We also found that the IR of CP after AP was 1.4 per 100 person-years (CI: 0.9-2; I 2 = 75%), while after RAP, it increased to 4.3 per 100 person-years (CI: 3.1-6.0; I 2 = 76%). The risk of bias was moderate in the majority of the included studies. Conclusion: Our results showed that RAP affects many patients with AP. Compared to patients with the first AP episode, RAP leads to a threefold higher IR for developing CP. Trial registration: Our protocol was registered on PROSPERO (CRD42021283252).
ABSTRACT
The effectiveness of psychological interventions (PI) for malignant diseases is controversial. We aimed to investigate the effect of PI on survival and quality of life (QoL) in patients with cancer. We performed a systematic search of MEDLINE, Cochrane, and Embase databases to identify randomized controlled trials comparing PI to standard care (PROSPERO registration number CRD42021282327). Outcomes were overall survival (OS), recurrence-free survival (RFS), and different domains of QoL. Subgroup analysis was performed based on the provider-, type-, environment-, duration of intervention; cancer stage, and type. Pooled hazard ratios (HR) and standardized mean difference (SMD) with 95% confidence intervals (CI) were calculated using a random-effects model. The OS and RFS did not differ significantly between the two groups (OS:HR = 0.97; CI 0.87-1.08; RFS:HR = 0.99; CI 0.84-1.16). However, there was significant improvement in the intervention group in all the analyzed domains of QoL; in the global (SMD = 0.65; CI 0.35-0.94), emotional (SMD = 0.64; CI 0.33-0.95), social (SMD = 0.32; CI 0.13-0.51) and physical (SMD = 0.33; CI 0.05-0.60) domains. The effect of PI on QoL was generally positive immediately, 12 and 24 weeks after intervention, but the effect decreased over time and was no longer found significant at 48 weeks. The results were better in the breast cancer group and early stages of cancer. PIs do not prolong survival, but they significantly improve the QoL of cancer patients. PI should be added as standard of care 3-4 times a year, at least for patients with early-stage cancer.

INTRODUCTION: Acute gastrointestinal bleeding (GIB) is a life-threatening emergency with a critical economic burden. As a result of bleeding, anaemia often requires intravenous or oral iron supplementation. Elderly patients are even more prone to untoward outcomes after hospital discharge if iron supplementation is inefficient. There is a gap in current guidelines on which supplementation route clinicians should choose. We aim to investigate the effect of one dose of intravenous iron therapy versus 3-month oral iron administration on anaemia in an elderly population. METHODS AND ANALYSIS: The FIERCE study is an open-label, randomised controlled, two-armed trial. At least 48 hours after the acute non-variceal GIB treatment, patients will be recruited in participating centres. A random sequence generator will allocate the participants to group A (intravenous ferric carboxymaltose, 1000 mg) or group B (oral ferrous sulfate (FS), ca. 200 mg every day) with an allocation ratio of 1:1 on the day of the planned discharge from the hospital. Randomisation will be stratified for participating centres and the need for transfusion within the same hospitalisation before recruitment to the trial. Quality of life assessment, functional measurement and laboratory tests will be performed at baseline, 1 and 3 months±7 days after enrolment to the trial. The primary endpoint is a composite endpoint, including all-cause mortality, anaemia-associated unplanned emergency visit and anaemia-associated unplanned hospital admission within 3 months of enrolment in the trial. ETHICS AND DISSEMINATION: The study has been approved by the relevant organisation, the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (46395-5/2021/EÜIG). We will disseminate our results to the medical community and will publish our results in peer-reviewed journals. TRIAL REGISTRATION: The trial has been registered at ClinicalTrials.gov (NCT05060731).

BACKGROUND: Anaemia and osteoporotic fractures are both major health problems among older adults worldwide. OBJECTIVES: Previous studies suggest that anaemia may be associated with elevated fracture risk among older adults; however, the exact relationship between them is unknown. We aimed to investigate the association between anaemia and fracture risk. METHODS: A comprehensive literature search was performed in four medical databases. We included articles that were published from inception to February 18, 2021. Odds ratios (ORs), hazard ratios (HRs) with 95% confidence intervals (CIs), and original raw incidences from studies comparing fracture rates in anaemic versus non-anaemic patients were extracted and pooled with the random-effects model. I2 test was used to assess heterogeneity. Risk of bias assessment was performed using the Quality of Prognostic Studies tool. PROSPERO: CRD42021241109. RESULTS: A total of 13 studies were identified; 8 of them were included in the quantitative synthesis. Anaemia was found to be a risk factor for fracture compared to non-anaemia. Anaemia increased hip fracture risk in both older men (HR = 1.71; CI: 1.46-2.00, p< 0.001, I2 = 83.2%) and women (HR = 1.31; CI: 1.13-1.52, p< 0.001), but the fracture risk was more increased among men. There was also an increased chance of hip fracture in the presence of anaemia in populations, including both older men and women (OR = 1.64; CI: 1.35-2.01, p< 0.001, I2 = 61.1%). Anaemia was also associated with increased vertebral (HR = 1.21; CI: 1.04-1.40, p = 0.012) and all-type (HR = 1.49; CI: 1.19-1.86, p< 0.001) fracture risk in older men. CONCLUSION: Our results suggest that there is a significant relationship between anaemia and fracture risk in older adults. This association is stronger among older men than women and differs in the different types of fractures.

Introduction: Dyspeptic symptoms are frequent in the general population, with a high socioeconomic burden. Helicobacter pylori (H. pylori) might be a possible etiological factor; however, it is also common in H. pylori negative gastritis. Clarification of the underlying aetiology might be beneficial to set up the optimal treatment strategy for dyspepsia and chronic gastritis (CG) itself. We aimed to assess the prevalence of dyspeptic symptoms in patients with H. pylori negative CG and explore autoimmunity's possible role. Methods: This retrospective study included data from patients with H. pylori negative CG. Exclusion criteria were (1) acute gastritis; (2) reactive gastropathy; (3) subjects without any serology testing results; (4) H. pylori positivity; (5) presence of atrophy, intestinal metaplasia (IM), gastroesophageal reflux disease (GERD), ulcer, or cancer. The following endpoints were assessed (1) the rate of dyspepsia-like symptoms; (2) association between dyspepsia and autoimmune disease-related seromarker positivity (AISP); (3) frequency of other symptoms in CG and its association with AISP; (4) location of the inflammation and its association with AISP. Results: From a total of 285 patients, 175 were included in this study. Among these patients, 95 experienced dyspeptic symptoms (54.29%) and were associated more with AISP (p = 0.012), especially with celiac seropositivity (p = 0.045), anti-neutrophil cytoplasmic antibody (ANCA) and anti-Saccharomyces cerevisiae antibodies (ASCA) positivity (p = 0.043). A significant association was not found with other tested autoimmune (AI)-related antibody positivity. Conclusion: Positivity of seromarkers of autoimmune diseases in chronic gastritis may predispose to have dyspeptic symptoms and may be the causative factor behind some cases of uninvestigated dyspepsia. These data suggest that further prospective studies are needed to clarify whether screening for autoantibodies in patients with dyspepsia is cost-effective and helps the earlier diagnosis of autoimmune diseases.
ABSTRACT
BACKGROUND: Bearberry (Arctostaphylos uva-ursi) leaf is available as a treatment of uncomplicated cystitis in several European countries. The antimicrobial activity of its extracts and some of its individual constituents has been observed in vitro; however, the efficacy of bearberry compared with standard antimicrobial therapy has not been assessed yet. OBJECTIVE: The objective of the study is to assess the safety and non-inferiority of bearberry as an alternative therapy in the treatment of acute uncomplicated cystitis in comparison with standard antibiotic therapy (fosfomycin). METHODS AND ANALYSIS: This is a randomised controlled double-blinded multicentre trial. Eligible patients will be premenopausal women with a sum score of ≥6 for the typical acute uncomplicated cystitis symptoms (frequency, urgency, painful urination, incomplete emptying, suprapubic pain and visible haematuria) reported on the Acute Cystitis Symptom Score (ACSS) typical domain and pyuria. Patients will be randomly assigned to receive 3 g single dose of fosfomycin powder and two placebo tablets three times a day for 7 days or B a single dose of placebo powder and two tablets containing a dry extract of Uvae ursi folium. At least 504 patients (allocated as 1:1) will need to be enrolled to access non-inferiority with a non-inferiority limit of 14% for the primary endpoint.Improvement of symptoms of uncomplicated cystitis (based on the ACSS score) at day 7 is defined as the primary endpoint, whereas several secondary endpoints such as the number and ratio of patients with bacteriuria at day 7, frequency and severity of side effects; recurrence of urinary tract infection, concurrent use of other over the counter (OTC) medications and food supplements will be determined to elucidate more detailed differences between the groups. The number of recurrences and medications taken for treatment will be monitored for a follow-up period of 90 days (80-100 days). ETHICS AND DISSEMINATION: This study has been approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (IV/4225-1/2021/EKU). The results will be disseminated by publication of peer-reviewed manuscripts. TRIAL REGISTRATION NUMBER: NCT05055544.

Background and Aims: Pancreatic ductal adenocarcinoma has one of the worst prognosis of all malignancies. This investigated the relationship between the preoperative serum carbohydrate antigen 19-9 and surgical resectability. Methods: A systematic search was performed in three databases (MEDLINE, EMBASE, and Web of Science) to compare the surgical resectability of pancreatic ductal adenocarcinoma in patients with high and low preoperative serum carbohydrate antigen 19-9 values. The receiving operating characteristic curves were constructed and the weighted mean differences for preoperative serum carbohydrate antigen 19-9 levels of resectable and unresectable groups of patients were calculated. The PROSPERO registration number is CRD42019132522. Results: Results showed that there was a significant difference in resectability between the low and high carbohydrate antigen 19-9 groups. Six out of the eight studies utilised receiver operating characteristic curves in order to find the cut-off preoperative carbohydrate antigen 19-9 levels marking unresectability. The overall result from the pooled area under curve values from the receiver operating characteristic curves was 0.794 (CI: 0.694-0.893), showing that the preoperative carbohydrate antigen 19-9 level is a "fair" marker of resectability. The result of the pooled weighted mean differences was 964 U/ml (p < 0.001) showing that there is a significant carbohydrate antigen 19-9 difference between the resectable and unresectable groups. Based on the results of the I-squared test, the result was 87.4%, accounting for "considerable" heterogeneity within the population. Conclusion: Carbohydrate antigen 19-9 is not a reliable marker of unresectability, it should not be used on its own in surgical decision-making.

BACKGROUND AND AIMS: The underlying aetiology of chronic gastritis (CG) often remains unknown due to its underrated significance in clinical practice. However, the role of chronic inflammation of the stomach in the development of atrophy, intestinal metaplasia (IM) and eventually of gastric cancer is well documented. We aimed to explore the possible aetiological factors of CG, determine the prevalence of systemic autoimmune disorders in patients with CG of unknown aetiology, and clarify the role of autoantibodies in the development of precancerous lesions in the stomach. METHODS: This is a retrospective, cross-sectional study, conducted from January 2016 to January 2020, including data from 175 patients with CG. Exclusion criteria were: (1) acute gastritis; (2) reactive gastropathy; (3) gastric cancer; (4) subjects without any serology testing results; and (5) Helicobacter pylori positivity. The primary endpoint was a composite endpoint involving gastric atrophy and IM. RESULTS: Fifty-five per cent of patients with CG had autoantibodies. Systemic lupus erythematosus (SLE)-related antibodies were positive in most of the cases, including antinuclear antibody (ANA) positivity, which was found in 19.13% of the patients. Autoimmune positivity was shown to be associated with precancerous lesions in the stomach (p<0.001): IM, atrophy and IM with atrophy. Anti-parietal cell antibody positivity seems to be a significant risk factor for IM and IM with atrophy. Autoimmune thyroiditis-related antibodies and ANA positivity by itself were only associated with atrophy; SLE-related antibodies and inflammatory bowel diseases related antibodies (ASCA and ANCA) correlated either with IM or with atrophy. No significant relation was found between any other investigated autoimmune disease-related antibodies and precancerous lesions. CONCLUSIONS: Autoimmune positivity often underlies gastritis of unknown aetiology and predisposes to precancerous lesions in the stomach. These antibodies can serve as non-invasive markers for the of optimal timing of an endoscopic follow-up strategy. Furthermore, CG can be an early symptom of a systemic autoimmune disorder.

Dronabinol, a natural cannabinoid, and its semi-synthetic derivative, nabilone, are marketed as medicines in several countries. The aim of our work was to systematically evaluate the frequency of adverse events related to dronabinol or nabilone treatment compared to placebo. Scientific databases were searched for placebo-controlled clinical studies of patients receiving either dronabinol or nabilone therapy with placebo control groups. This meta-analysis was reported following the PRISMA guidelines using the PICO format, and it was registered with the PROSPERO register. There were 16 trials included in the meta-analysis. In the nabilone studies, drowsiness was more than 7 times as frequent in patients treated with nabilone than in the placebo group (OR: 7.25; 95% CI: 1.64-31.95), and the risk of dizziness (OR: 21.14; 95% CI: 2.92-152.75) and dry mouth was also higher (OR: 17.23; 95% CI: 4.33-68.55). The frequency of headache was not different in the two groups. In case of dronabinol, the frequency of dry mouth (OR: 5.58; 95% CI: 3.19-9.78), dizziness (OR: 4.60 95% CI: 2.39-8.83) and headache (OR: 2.90; 95% CI: 1.07-7.85) was significantly higher in the dronabinol groups, whereas in case of nausea, drowsiness and fatigue there was no difference. The severity of adverse events was typically mild-to-moderate and transient. In a risk-benefit assessment, these adverse effects are acceptable compared to the achievable benefit. However, considering the diversity of the adverse effects, more studies are needed to provide a more accurate assessment on the side effect profiles of these two compounds.
ABSTRACT
Background: Gastric cancer is one of the most common cancers worldwide, with a high mortality rate. The potential etiological role of autoimmune (AI) disorders has been described in gastric cancer; however, the literature is controversial. This study aims to provide a comprehensive summary of the association between autoimmune disorders and the incidence of gastric cancer. Methods: This study was registered on PROSPERO under registration number CRD42021262875. The systematic literature search was conducted in four scientific databases up to May 17, 2021. Studies that reported standardized incidence rate (SIR) of gastric cancer in autoimmune disorders were eligible. We calculated pooled SIRs with 95% confidence intervals (CIs) in this meta-analysis. Results: We included 43 articles describing 36 AI disorders with data of 499,427 patients from four continents in our systematic review and meta-analysis. Significantly increased incidence of gastric cancer was observed in dermatomyositis (SIR = 3.71; CI: 2.04, 6.75), pernicious anemia (SIR = 3.28; CI: 2.71, 3.96), inflammatory myopathies (SIR = 2.68; CI:1.40; 5.12), systemic lupus erythematosus (SIR = 1.48; CI: 1.09, 2.01), diabetes mellitus type I (SIR = 1.29; CI:1.14, 1,47), and Graves' disease (SIR = 1.28; CI: 1.16, 1.41). No significant associations could be found regarding other AI disorders. Conclusions: Pernicious anemia, Graves' disease, dermatomyositis, diabetes mellitus type I, inflammatory myopathies, and systemic lupus erythematosus are associated with higher incidence rates of gastric cancer. Therefore, close gastroenterological follow-up or routinely performed gastroscopy and application of other diagnostic measures may be cost-effective and clinically helpful for patients diagnosed with these autoimmune diseases.

BACKGROUND: Pseudocysts being the most frequent local complications of acute pancreatitis (AP) have substantial effect on the disease course, hospitalization and quality of life of the patient. Our study aimed to understand the effects of pre-existing (OLD-P) and newly developed (NEW-P) pseudocysts on AP. METHODS: Data were extracted from the Acute Pancreatitis Registry organized by the Hungarian Pancreatic Study Group (HPSG). 2275 of 2461 patients had uploaded information concerning pancreatic morphology assessed by imaging technique. Patients were divided into "no pseudocyst" (NO-P) group, "old pseudocyst" (OLD-P) group, or "newly developed pseudocyst" (NEW-P) groups. RESULTS: The median time of new pseudocyst development was nine days from hospital admission and eleven days from the beginning of the abdominal pain. More NEW-P cases were severe (15.9% vs 4.7% in the NO-P group p < 0.001), with longer length of hospitalization (LoH) (median: 14 days versus 8 days, p < 0.001), and were associated with several changed laboratory parameters. OLD-P was associated with male gender (72.2% vs. 56.1%, p = 0.0014), alcoholic etiology (35.2% vs. 19.8% in the NO-P group), longer hospitalization (median: 10 days, p < 0.001), a previous episode of AP (p < 0.001), pre-existing diagnosis of chronic pancreatitis (CP) (p < 0.001), current smoking (p < 0.001), and increased alcohol consumption (unit/week) (p = 0.014). CONCLUSION: Most of the new pseudocysts develop within two weeks. Newly developing pseudocysts are associated with a more severe disease course and increased length of hospitalization. Pre-existing pseudocysts are associated with higher alcohol consumption and smoking. Because CP is more frequently associated with a pre-existing pseudocyst, these patients need closer attention after AP.
ABSTRACT
INTRODUCTION: Current guidelines recommend intravenous (IV) proton pump inhibitor (PPI) therapy in peptic ulcer bleeding (PUB). We aimed to compare the efficacy of oral and IV administration of PPIs in PUB. METHODS: We performed a systematic search in 4 databases for randomized controlled trials, which compared the outcomes of oral PPI therapy with IV PPI therapy for PUB. The primary outcomes were 30-day recurrent bleeding and 30-day mortality. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for dichotomous outcomes, while weighted mean differences (WMDs) with CI were calculated for continuous outcomes in meta-analysis. The protocol was registered a priori onto PROSPERO (CRD42020155852). RESULTS: A total of 14 randomized controlled trials reported 1,951 peptic ulcer patients, 977 and 974 of which were in the control and intervention groups, respectively. There were no statistically significant differences between oral and IV administration regarding 30-day rebleeding rate (OR = 0.96, CI: 0.65-1.44); 30-day mortality (OR = 0.70, CI: 0.35-1.40); length of hospital stay (WMD = -0.25, CI: -0.93 to -0.42); transfusion requirements (WMD = -0.09, CI: -0.07 to 0.24); need for surgery (OR = 0.91, CI: 0.40-2.07); further endoscopic therapy (OR = 1.04, CI: 0.56-1.93); and need for re-endoscopy (OR = 0.81, CI: 0.52-1.28). Heterogeneity was negligible in all analysis, except for the analysis on the length of hospitalization (I2 = 82.3%, P = 0.001). DISCUSSION: Recent evidence suggests that the oral administration of PPI is not inferior to the IV PPI treatment in PUB after endoscopic management, but further studies are warranted.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an infection with possible serious consequences. The plasma of recovered patients might serve as treatment, which we aim to assess in the form of a prospective meta-analysis focusing on mortality, multi-organ failure, duration of intensive care unit stay, and adverse events. METHODS: A systematic search was conducted to find relevant registered randomized controlled trials in five trial registries. A comprehensive search will be done continuously on a monthly basis in MEDLINE (via PubMed), Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science to find the results of previously registered randomized controlled trials. The selection will be done by two independent authors. Data extraction will be carried out by two other independent reviewers. Disagreements will be resolved by a third investigator. An update of the search of the registries and the first search of the databases will be done on the 21st of July. Data synthesis will be performed following the recommendations of the Cochrane Collaboration. In the case of dichotomous outcomes (mortality and organ failure), we will calculate pooled risk ratios with a 95% confidence interval (CI) from two-by-two tables (treatment Y/N, outcome Y/N). Data from models with multivariate adjustment (hazard ratios, odds ratio, risk ratio) will be preferred for the analysis. P less than 0.05 will be considered statistically significant. In the case of ICU stay, weighted mean difference with a 95% confidence interval will be calculated. Heterogeneity will be tested with I2, and χ2 tests. Meta-analysis will be performed if at least 3 studies report on the same outcome and population. DISCUSSION: Convalescent plasma therapy is a considerable alternative in COVID-19, which we aim to investigate in a prospective meta-analysis.

Background: We aimed to perform a systematic search and meta-analysis to evaluate the prognostic value of on-admission liver function tests and pre-existing liver diseases on the clinical course of coronavirus disease 2019 (COVID-19). Methods: The study was registered on PROSPERO (CRD42020182902). We searched five databases between 01/01/2020 and 04/23/2020. Studies that reported on liver-related comorbidities and/or laboratory parameters in patients with COVID-19 were included. The main outcomes were COVID-19 severity, intensive care unit (ICU) admission, and in-hospital mortality. Analysis of predictive models hierarchical summary receiver-operating characteristic (HSROC) was conducted with a 95% confidence interval (CI). Results: Fifty studies were included in the meta-analysis. High specificity was reached by acute liver failure associated by COVID-19 (0.94, 95% CI: 0.71-0.99) and platelet count (0.94, 95% CI: 0.71-0.99) in the case of mortality; chronic liver disease (CLD) (0.98, 95% CI: 0.96-0.99) and platelet count (0.82, 95% CI: 0.72-0.89) in the case of ICU requirement; and CLD (0.97, 95% CI: 0.95-0.98), chronic hepatitis B infection (0.97, 95% CI: 0.95-0.98), platelet count (0.86, 95% CI: 0.77-0.91), and alanine aminotransferase (ALT) (0.80, 95% CI: 0.66-0.89) and aspartate aminotransferase (AST) (0.84, 95% CI: 0.77-0.88) activities considering severe COVID-19. High sensitivity was found in the case of C-reactive protein (CRP) for ICU requirement (0.92, 95% CI: 0.80-0.97) and severe COVID-19 (0.91, 95% CI: 0.82-0.96). Conclusion: On-admission platelet count, ALT and AST activities, CRP concentration, and the presence of acute and CLDs predicted the severe course of COVID-19. To highlight, pre-existing liver diseases or acute liver injury associated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection plays an important role in the prediction of mortality.
ABSTRACT
Introduction: Bisphosphonates (BPs) are first-line therapy for osteoporosis. Adherence is usually low in chronic, asymptomatic diseases, but gastrointestinal (GI) side-effects can also contribute to low adherence in BP therapy and may necessitate a review by a gastroenterologist with or without gastroscopy. Aims: Our meta-analysis aims to determine the risk of severe GI adverse events due to oral BP therapy in osteoporotic patients. Methods: A systematic search was conducted in three databases up to September 2020 for randomized controlled trials (RCTs) detailing GI adverse events in adults with osteoporosis on BP compared to placebo. Risk ratios (RRs) with 95% confidence intervals (CI) were calculated for non-severe and severe adverse events indicating endoscopic procedure with the random-effects model. Statistical heterogeneity was assessed using chi2 and I2 statistics. Results: Forty-two RCTs with 39,047 patients with 9,999 non-severe and 1,503 severe GI adverse events were included. The incidence of non-severe and severe adverse events ranged between 0.3-54.9 and 0-10.3%, respectively. There was no difference between BP and control groups in terms of the risk of non-severe or severe side effects: RR=1.05 (CI: 0.98-1.12), I2 = 48.1%, and RR=1.01 (CI: 0.92-1.12), I2 = 0.0%, respectively. Subgroup analysis of the most commonly used BP, once-weekly alendronate 70 mg, revealed an association between bisphosphonates and the risk of non-severe GI adverse events, RR=1.16 (CI: 1.00-1.36), I2 = 40.7%, while the risk of severe GI side effects was not increased in this subgroup, RR=1.20 (CI: 0.83-1.74), I2 = 0.0%. Conclusion: Our results show that bisphosphonates do not increase the risk of severe GI adverse events. However, the marked variability of the screening for side effects in the included studies, and the fact that in most of the studies GI diseases were exclusion criteria limits the strenght of evidence of our results. The conclusions drawn from the meta-analysis are therefore restricted to selected populations, and the results must be interpreted with caution.

BACKGROUND: Early reports indicate that COVID-19 may require intensive care unit (ICU) admission in 5-26% and overall mortality can rise to 11% of the recognised cases, particularly affecting the elderly. There is a lack of evidence-based targeted pharmacological therapy for its prevention and treatment. We aim to compare the effects of a World Health Organization recommendation-based education and a personalised complex preventive lifestyle intervention package (based on the same WHO recommendation) on the outcomes of the COVID-19. METHODS: PROACTIVE-19 is a pragmatic, randomised controlled clinical trial with adaptive "sample size re-estimation" design. Hungarian population over the age of 60 years without confirmed COVID-19 will be approached to participate in a telephone health assessment and lifestyle counselling voluntarily. Volunteers will be randomised into two groups: (A) general health education and (B) personalised health education. Participants will go through questioning and recommendation in 5 fields: (1) mental health, (2) smoking habits, (3) physical activity, (4) dietary habits, and (5) alcohol consumption. Both groups A and B will receive the same line of questioning to assess habits concerning these topics. Assessment will be done weekly during the first month, every second week in the second month, then monthly. The composite primary endpoint will include the rate of ICU admission, hospital admission (longer than 48 h), and mortality in COVID-19-positive cases. The estimated sample size is 3788 subjects per study arm. The planned duration of the follow-up is a minimum of 1 year. DISCUSSION: These interventions may boost the body's cardiovascular and pulmonary reserve capacities, leading to improved resistance against the damage caused by COVID-19. Consequently, lifestyle changes can reduce the incidence of life-threatening conditions and attenuate the detrimental effects of the pandemic seriously affecting the older population. TRIAL REGISTRATION: The study has been approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (IV/2428- 2 /2020/EKU) and has been registered at clinicaltrials.gov ( NCT04321928 ) on 25 March 2020.

INTRODUCTION: Some studies suggest that the accuracy of Helicobacter pylori diagnostic tests is decreased in peptic ulcer bleeding (PUB). We aimed to assess the accuracy of diagnostic tests for H. pylori in patients with PUB in a diagnostic test accuracy (DTA) network meta-analysis. METHODS: A systematic search was carried out in seven databases until November 2019. We collected or calculated true and false positive and negative values, and constructed 2×2 diagnostic contingency tables with reference standards including histology, rapid urease test, urea breath test, serology, stool antigen test, culture, and polymerase chain reaction. We ranked the index tests by the superiority indices (SI) and calculated pooled sensitivity and specificity of each test. DISCUSSION: Our search yielded 40 eligible studies with 27 different diagnostic strategies for H. pylori. In 32 articles, the reference standard was a combination of multiple tests. In 12 studies, the index tests were compared with a single testing method. We analyzed seven networks with the reference standards against a single or a combination of diagnostic index tests. None of the index tests had better diagnostic accuracy (SI between 9.94 and 2.17) compared with the individual index tests as all the confidence intervals included 1. Combined testing strategies had higher sensitivities (0.92-0.62) and lower specificities (0.85-0.46) while single tests proved to have higher specificities (0.83-0.77) and lower sensitivities (0.73-0.42). CONCLUSION: Use of combined tests may have a rationale in clinical practice due to their higher sensitivities. The differences between the included DTA studies limited the comparison of the testing strategies.
