ABSTRACT
BACKGROUND: Neoadjuvant therapy is an essential modality for reducing the clinical stage of esophageal cancer; however, the superiority of neoadjuvant chemotherapy (nCT) or neoadjuvant chemoradiotherapy (nCRT) is unclear. Therefore, a discussion of these two modalities is necessary. AIM: To investigate the benefits and complications of neoadjuvant modalities. METHODS: To address this concern, predefined criteria were established using the PICO protocol. Two independent authors performed comprehensive searches using predetermined keywords. Statistical analyses were performed to identify significant differences between groups. Potential publication bias was visualized using funnel plots. The quality of the data was evaluated using the Risk of Bias Tool 2 (RoB2) and the GRADE approach. RESULTS: Ten articles, including 1928 patients, were included for the analysis. Significant difference was detected in pathological complete response (pCR) [P < 0.001; odds ratio (OR): 0.27; 95%CI: 0.16-0.46], 30-d mortality (P = 0.015; OR: 0.4; 95%CI: 0.22-0.71) favoring the nCRT, and renal failure (P = 0.039; OR: 1.04; 95%CI: 0.66-1.64) favoring the nCT. No significant differences were observed in terms of survival, local or distal recurrence, or other clinical or surgical complications. The result of RoB2 was moderate, and that of the GRADE approach was low or very low in almost all cases. CONCLUSION: Although nCRT may have a higher pCR rate, it does not translate to greater long-term survival. Moreover, nCRT is associated with higher 30-d mortality, although the specific cause for postoperative complications could not be identified. In the case of nCT, toxic side effects are suspected, which can reduce the quality of life. Given the quality of available studies, further randomized trials are required.

Background: There were more than 1 million new cases of stomach cancer concerning oesophageal cancer, there were more than 600,000 new cases of oesophageal cancer in 2020. After a successful resection in these cases, the role of early oral feeding (EOF) was questionable, due to the possibility of fatal anastomosis leakage. It is still debated whether EOF is more advantageous compared to late oral feeding. Our study aimed to compare the effect of early postoperative oral feeding and late oral feeding after upper gastrointestinal resections due to malignancy. Methods: Two authors performed an extensive search and selection of articles independently to identify randomized control trials (RCT) of the question of interest. Statistical analyses were performed including mean difference, odds ratio with 95% confidence intervals, statistical heterogeneity, and statistical publication bias, to identify potential significant differences. The Risk of Bias and the quality of evidence were estimated. Results: We identified 6 relevant RCTs, which included 703 patients. The appearance of the first gas (MD = -1.16; p = 0.009), first defecation (MD = -0.91; p < 0.001), and the length of hospitalization (MD = -1.92; p = 0.008) favored the EOF group. Numerous binary outcomes were defined, but significant difference was not verified in the case of anastomosis insufficiency (p = 0.98), pneumonia (p = 0.88), wound infection (p = 0.48), bleeding (p = 0.52), rehospitalization (p = 0.23), rehospitalization to the intensive care unit (ICU) (p = 0.46), gastrointestinal paresis (p = 0.66), ascites (p = 0.45). Conclusion: Early postoperative oral feeding, compared to late oral feeding has no risk of several possible postoperative morbidities after upper GI surgeries, but has several advantageous effects on a patient's recovery.

ABSTRACT
Head and neck squamous cell carcinoma (HNSCC) is among the common tumors associated with high mortality. The aim of our meta-analysis was to determine how additional anti-epidermal growth factor receptor (EGFR) therapy to standard chemotherapy affects the progression-free (PFS) and overall survival (OS) of the patients, besides the most common side effects. We used CENTRAL, MEDLINE, and Embase databases until October 26, 2020, and included 13 eligible randomized controlled trials in our systematic research. The pooled hazard ratios (HR) for the main outcomes from the original data were estimated and for the other dichotomous outcomes, odds ratios (ORs) with their 95% confidence intervals (CI) were calculated. Addition of EGFR inhibitors to conventional chemotherapy significantly decreased the death and disease progression (for PFS HR: 0.68, 95% CI: 0.55-0.81, I2 = 65.5%, p = 0.005) and mortality (for OS HR: 0.83, 95% CI: 0.72-0.94, I2 = 42.3%, p = 0.076). In the EGFR inhibitor group, we revealed an increased chance of the over Grade 3 skin rashes (OR: 4.86; 95% CI: 1.52-15.49, I2 = 2.3%, p = 0.407), and all Grade skin rashes (OR: 18.32, 95% CI: 8.07-41.60, I2 = 56.6%, p = 0.032). Despite their unwanted dermatological side effects, the addition of EGFR inhibitors is recommended to be included in advanced HNSCC therapy.

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: Previous meta-analyses, with many limitations, have described the beneficial nature of minimal invasive procedures. AIM: To compare all modalities of esophagectomies to each other from the results of randomized controlled trials (RCTs) in a network meta-analysis (NMA). METHODS: We conducted a systematic search of the MEDLINE, EMBASE, Reference Citation Analysis (https://www.referencecitationanalysis.com/) and CENTRAL databases to identify RCTs according to the following population, intervention, control, outcome (commonly known as PICO): P: Patients with resectable esophageal cancer; I/C: Transthoracic, transhiatal, minimally invasive (thoracolaparoscopic), hybrid, and robot-assisted esophagectomy; O: Survival, total adverse events, adverse events in subgroups, length of hospital stay, and blood loss. We used the Bayesian approach and the random effects model. We presented the geometry of the network, results with probabilistic statements, estimated intervention effects and their 95% confidence interval (CI), and the surface under the cumulative ranking curve to rank the interventions. RESULTS: We included 11 studies in our analysis. We found a significant difference in postoperative pulmonary infection, which favored the minimally invasive intervention compared to transthoracic surgery (risk ratio 0.49; 95%CI: 0.23 to 0.99). The operation time was significantly shorter for the transhiatal approach compared to transthoracic surgery (mean difference -85 min; 95%CI: -150 to -29), hybrid intervention (mean difference -98 min; 95%CI: -190 to -9.4), minimally invasive technique (mean difference -130 min; 95%CI: -210 to -50), and robot-assisted esophagectomy (mean difference -150 min; 95%CI: -240 to -53). Other comparisons did not yield significant differences. CONCLUSION: Based on our results, the implication of minimally invasive esophagectomy should be favored.

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.

BACKGROUND: Pathology of the long head of the biceps tendon (LHBT) is a common disorder affecting muscle function and causing considerable pain for the patient. The literature on the two surgical treatment methods (tenotomy and tenodesis) is controversial; therefore, our aim was to compare the results of these interventions. METHODS: We performed a meta-analysis using the following strategy: (P) patients with LHBT pathology, (I) tenodesis, (C) tenotomy, (O) elbow flexion and forearm supination strength, pain assessed on the ten-point Visual Analog Scale (VAS), bicipital cramping pain, Constant, ASES, and SST score, Popeye deformity, and operative time. We included only randomized clinical trials. We searched five databases. During statistical analysis, odds ratios (OR) and weighted mean differences (WMD) were calculated for dichotomous and continuous outcomes, respectively, using the Bayesian method with random effect model. RESULTS: We included 11 studies in the systematic review, nine of these were eligible for the meta-analysis, containing data about 572 patients (279 in the tenodesis, 293 in the tenotomy group). Our analysis concluded that tenodesis is more beneficial considering 12-month elbow flexion strength (WMD: 3.67 kg; p = 0.006), 12-month forearm supination strength (WMD: 0.36 kg; p = 0.012), and 24-month Popeye deformity (OR: 0.19; p < 0.001), whereas tenotomy was associated with decreased 3-month pain scores on VAS (WMD: 0.99; p < 0.001). We did not find significant difference among the other outcomes. CONCLUSION: Tenodesis yields better results in terms of biceps function and is non-inferior regarding long-term pain, while tenotomy is associated with earlier pain relief.

Background Helicobacter pylori (H. pylori) infection affects ≈4.4 billion people worldwide. Several studies suggest that this pathogen impacts the digestive system, causing diverse and severe conditions, and results in extragastrointestinal disorders like vascular diseases. Our study aims to examine the association between H. pylori infection and carotid intima-media thickness. Methods and Results Electronic databases (MEDLINE, Embase, CENTRAL, Web of Science, and Scopus) were searched for studies, comparing the thickness of the carotid intima-media in H. pylori-infected and noninfected individuals listed until October 20, 2020. Statistical analyses were performed using the random effects meta-analysis of model of weighted mean differences with the corresponding 95% CI using the DerSimonian and Laird method. The protocol was registered in advance in PROSPERO (International Prospective Register of Systematic Reviews; CRD42021224485). Thirteen studies were found meeting inclusion criteria for our systematic review and meta-analysis, presenting data on the thickness of the carotid intima-media considering the presence of H. pylori infection. Altogether, 2298 individuals' data were included (1360 H. pylori positive, 938 negative). The overall carotid intima-media thickness was significantly larger among infected patients compared with uninfected participants (weighted mean difference: 0.07 mm; 95% CI, 0.02-0.12; P=0.004; I2=91.1%; P<0.001). In case of the right common carotid artery, the intima-media thickening was found to be significant as well (weighted mean difference, 0.08 mm; 95% CI, 0.02-0.13, P=0.007; I2=85.1%; P<0.001), while it showed no significance in the left common carotid artery (weighted mean difference, 0.12 mm; 95% CI, -0.05 to 0.28, P=0.176; I2=97.4%; P<0.001). Conclusions H. pylori infection is associated with increased carotid intima-media thickness. Therefore, the infection may indirectly contribute to the development of major vascular events.

BACKGROUND/OBJECTIVES: Acute recurrent pancreatitis (ARP) due to alcohol and/or tobacco abuse is a preventable disease which lowers quality of life and can lead to chronic pancreatitis. The REAPPEAR study aims to investigate whether a combined patient education and cessation programme for smoking and alcohol prevents ARP. METHODS AND ANALYSIS: The REAPPEAR study consists of an international multicentre randomised controlled trial (REAPPEAR-T) testing the efficacy of a cessation programme on alcohol and smoking and a prospective cohort study (REAPPEAR-C) assessing the effects of change in alcohol consumption and smoking (irrespective of intervention). Daily smoker patients hospitalised with alcohol-induced acute pancreatitis (AP) will be enrolled. All patients will receive a standard intervention priorly to encourage alcohol and smoking cessation. Participants will be subjected to laboratory testing, measurement of blood pressure and body mass index and will provide blood, hair and urine samples for later biomarker analysis. Addiction, motivation to change, socioeconomic status and quality of life will be evaluated with questionnaires. In the trial, patients will be randomised either to the cessation programme with 3-monthly visits or to the control group with annual visits. Participants of the cessation programme will receive a brief intervention at every visit with direct feedback on their alcohol consumption based on laboratory results. The primary endpoint will be the composite of 2-year all-cause recurrence rate of AP and/or 2-year all-cause mortality. The cost-effectiveness of the cessation programme will be evaluated. An estimated 182 participants will be enrolled per group to the REAPPEAR-T with further enrolment to the cohort. ETHICS AND DISSEMINATION: The study was approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (40394-10/2020/EÜIG), all local ethical approvals are in place. Results will be disseminated at conferences and in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04647097.

BACKGROUND: Around 20% of patients with acute pancreatitis (AP) will develop acute recurrent pancreatitis (ARP) and 10% will progress to chronic pancreatitis. While interventions to avoid recurrences exist for the two most common causes - abstinence for alcoholic and cholecystectomy for biliary pancreatitis - the are no known preventive measures in idiopathic ARP. Though it is not included in any of the guidelines, a low-fat diet is often recommended. Our aim is to test dietary fat reduction's effect on AP recurrence in a randomized controlled setting, in order to provide high-quality evidence for the validity of such an intervention. METHODS, DESIGN: Participants with at least 2 episodes of AP in the preceding 2 years of which the last episode was idiopathic will be randomized to one of two diets with different fat contents: a 'reduced fat diet' (15% fat, 65% carbohydrate, 20% protein) and a 'standard healthy diet' (30% fat, 50% carbohydrate, 20% protein; based on WHO recommendations). Participants will be followed-up for 2 years (visits will be scheduled for months 3, 6, 12, 18 and 24) during which they will receive a repeated session of nutritional guidance, complete food frequency questionnaires and data on relapse, mortality, BMI, cardiovascular parameters and serum lipid values will be collected. DISCUSSION: This study will determine the effect of modifying the dietary fat content on AP recurrence, mortality, serum lipids and weight loss in idiopathic cases.

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.

INTRODUCTION: Sepsis and septic shock have mortality rates between 20% and 50%. In sepsis, the immune response becomes dysregulated, which leads to an imbalance between proinflammatory and anti-inflammatory mediators. When standard therapeutic measures fail to improve patients' condition, additional therapeutic alternatives are applied to reduce morbidity and mortality. One of the most recent alternatives is extracorporeal cytokine adsorption with a device called CytoSorb. This study aims to compare the efficacy of standard medical therapy and continuous extracorporeal cytokine removal with CytoSorb therapy in patients with early refractory septic shock. Furthermore, we compare the dosing of CytoSorb adsorber device changed every 12 or 24 hours. METHODS AND ANALYSIS: It is a prospective, randomised, controlled, open-label, international, multicentre, phase III study. Patients fulfilling the inclusion criteria will be randomly assigned to receive standard medical therapy (group A) or-in addition to standard treatment-CytoSorb therapy. CytoSorb treatment will be continuous and last for at least 24 hours, CytoSorb adsorber device will be changed every 12 (group B) or 24 hours (group C). Our primary outcome is shock reversal (no further need or a reduced (≤10% of the maximum dose) vasopressor requirement for 3 hours) and time to shock reversal (number of hours elapsed from the start of the treatment to shock reversal).Based on sample size calculation, 135 patients (1:1:1) will need to be enrolled in the study. A predefined interim analysis will be performed after reaching 50% of the planned sample size, therefore, the corrected level of significance (p value) will be 0.0294. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (OGYÉI/65049/2020). Results will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT04742764; Pre-results.

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
With repeated positivity being an undiscovered and major concern, we aimed to evaluate which prognostic factors may impact repeated SARS-CoV-2 positivity (RSP) and their association with immunoglobulin detectability among recovered patients. A systematic literature search was performed on 5 April 2021. Cohort studies with risk factors for repeated RSP or information about the immunoglobulin response (immunoglobulin M (IgM) and/or immunoglobulin G (IgG)) were included in this analysis. The main examined risk factors were severity of the initial infection, body mass index (BMI), length of hospitalization (LOH), age, and gender, for which we pooled mean differences and odds ratios (ORs). Thirty-four cohort studies (N = 9269) were included in our analysis. We found that increased RSP rate might be associated with IgG positivity; IgG presence was higher in RSP patients (OR: 1.72, CI: 0.87-3.41, p = 0.117). Among the examined risk factors, only mild initial disease course showed a significant association with RSP (OR: 0.3, CI: 0.14-0.67, p = 0.003). Age, male gender, BMI, LOH, and severity of the first episode do not seem to be linked with repeated positivity. However, further prospective follow-up studies focusing on this topic are required.

Repeated positivity and reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) is a significant concern. Our study aimed to evaluate the clinical significance of repeatedly positive testing after coronavirus disease 2019 (COVID-19) recovery. We performed a systematic literature search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. With available individual patient data reporting on repeatedly SARS-CoV-2 positive (RSP) patients, case reports, and case series were included in this analysis. We performed a descriptive analysis of baseline characteristics of repeatedly positive cases. We assessed the cases according to the length of their polymerase chain reaction (PCR) negative interval between the two episodes. Risk factors for the severity of second episodes were evaluated. Overall, we included 123 patients with repeated positivity from 56 publications, with a mean repeated positivity length of 47.8 ± 29.9 days. Younger patients were predominant in the delayed (>90 days) recurrent positive group. Furthermore, comparing patients with RSP intervals of below 60 and above 60 days, we found that a more severe disease course can be expected if the repeated positivity interval is shorter. Severe and critical disease courses might predict future repeatedly positive severe and critical COVID-19 episodes. In conclusion, our results show that the second episode of SARS-CoV-2 positivity is more severe if it happens within 60 days after the first positive PCR. On the other hand, the second episode's severity correlates with the first.

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.
