The Effects of Gluten-free Diet on Body Mass Indexes in Adults with Celiac Disease: A Systematic Review and Meta-analysis of Observational Studies.

GOALS AND BACKGROUND: Gluten-free diet (GFD) includes a higher intake of sugars and fats. Previous studies have investigated its effect on body mass index (BMI) in celiac disease (CD) patients but had contradictive conclusions. Thus, we conducted a systematic review and meta-analysis examining the effect of GFD on BMI in CD patients. STUDY: Systematically, we conducted literature research using Medline, Scopus, and Embase, and we identified 1565 potential studies/abstracts. Only studies of patients with CD under a GFD with recorded BMI before and after dietary intervention were included. Subgroup analyses based on study design and BMI categories were performed. We calculated the pooled odds ratios (ORs) and 95% confidence intervals (Cls) for the number of patients in each BMI group according to the World Health Organization (WHO) definitions after GFD using fixed and random effect meta-analysis. RESULTS: The analysis included 10 studies and 38 sub-studies/data sets, which encompassed 2450 patients from 5 countries. We found nonsignificant odds for changing the BMI group (pooled OR 0.972, 95% CI: 0.858-1.101, P=0.65) after GFD. However, looking specifically at BMI subgroups, we found higher odds for BMI category change after GFD in underweight patients (OR 0.588, 95% CI: 0.479-0.723, P <0.001), and overweight patients,25

[THE IMPACT OF REGULATION AND CENTRAL MANAGEMENT ON PATIENT SAFETY IN ISRAEL].

INTRODUCTION: An adverse event is defined as an unwanted and unexpected occurrence in a medical process that may end in harm to the patient. In the USA the number of deaths due to failures reaches 253,000 per year. In Israel, over 10,000 deaths occur per year due to errors in the medical treatment of hospitalized patients, the third most common cause of death after heart disease and cancer. The main cause of failures in medical diagnosis and treatment is the complexity of the medical profession. A large number of caregivers in different medical disciplines are needed to treat one patient, therefore there are many errors, especially regarding communication between therapists. The Israeli health system has been operating with a budget deficit for many years and an addition of at least NIS 20 billion is needed to bring it to optimal functioning. The number of doctors, nurses, and hospital beds per 1000 inhabitants is significantly less than the average of the OECD countries. When there was a 30% increase in the population of Israel it was necessary to enhance the existing situation, with the addition of 7700 hospital beds, but only 1400 were added. This caused a decrease from 2.1 beds per 1000 residents to 1.8 beds per 1000 residents. There is an urgent need to change the elements of treatment safety in the Ministry of Health's strategic plan. An administration for quality, treatment safety, risk management in medicine, and accreditation should be established which, in addition to the care quality division, will include a safety division with investigation and monitoring units and will prepare strategic improvement plans, and a university-level research institute with researchers, computing, statistics, and information gathering units. The institute will receive all reports of adverse events, results of investigations, inspection committees, control and quality committees, relevant verdicts, and updated literature reviews, for research and systemic learning. Strategic plans will be prepared to prevent failures in diagnosis and medical treatment, leading to a decrease in mortality due to adverse events and the significant expenses involved.

Mucin Expression in the Small Bowel of Celiac Disease: A Systematic Review.

BACKGROUND: Mucins, heavily glycosylated glycoproteins, are synthesized by mucosal surfaces and play an important role in healthy and malignant states. Changes in mucin synthesis, expression, and secretion may be a primary event or may be secondary to inflammation and carcinogenesis. OBJECTIVES: To assess current knowledge of mucin expression in the small bowel of celiac disease (CD) patients and to determine possible associations between mucin profile and gluten-free diet. METHODS: Medical literature searches of articles in English were conducted using the terms mucin and celiac. Observational studies were included. Pooled odds ratios and 95% confidence intervals were calculated. RESULTS: Of 31 articles initially generated by a literature search, 4 observational studies that fulfilled the inclusion criteria remained eligible for meta-analysis. These studies included 182 patients and 148 controls from four countries (Finland, Japan, Sweden, United States). Mucin expression was significantly increased in small bowel mucosa of CD patients than in normal small bowel mucosa (odds ratio [OR] 7.974, 95% confidence interval [95%CI] (1.599-39.763), P = 0.011] (random-effect model). Heterogeneity was significant: Q = 35.743, df (Q) = 7, P < 0.0001, I2 = 80.416%. ORs for MUC2 and MUC5AC expression in the small bowel mucosa of untreated CD patients were 8.837, 95%CI 0.222-352.283, P = 0.247 and 21.429, 95%CI 3.883-118.255, P < 0.0001, respectively. CONCLUSIONS: Expression of certain mucin genes in the small bowel mucosa of CD patients is increased and may serve as a diagnostic tool and assist in surveillance programs.

Difference Between COVID-19 Alpha Variant B.1.1.7 and the Original Virus in Gastrointestinal Symptoms and Mortality: Does a Negative Correlation Exist?

BACKGROUND: Up to half the patients diagnosed with acute coronavirus disease 2019 (COVID-19) presented with gastrointestinal symptoms. Gastric mucosal cells, enterocytes, and colonocytes express the viral entry receptor angiotensin-converting enzyme 2 (ACE2) and coreceptor transmembrane protease serine 2 (TMPRSS2) and are prone to infection. Direct infection of gastrointestinal epithelial cells has been demonstrated. COVID-19 disease was first diagnosed in Israel at the end of February 2020 with 842,536 confirmed cases and 6428 deaths by the end of June 2021. In our multicenter, retrospective cohort study, we looked for gastrointestinal signs and symptoms in two periods and correlated them with mortality. Period 1 included the first and second waves and the original virus. Period 2 represented the third wave and the alpha variant. OBJECTIVES: To reveal gastrointestinal signs and symptoms in two periods and correlate them with mortality. METHODS: From 22,302 patients hospitalized in general medical centers, we randomly selected 3582 from Period 1 and 1106 from Period 2. The study was performed before vaccinations were available. RESULTS: Gastrointestinal signs and symptoms, diarrhea, vomiting, abdominal pain, and taste/smell loss were significantly more prevalent during Period 1. Thirty-day mortality and in-hospital mortality were significantly higher in Period 2 than in Period 1, 25.20% vs. 13.68%, and 21.17% vs. 12.87%, respectively (P < 0.001). CONCLUSIONS: Thirty-day mortality and in-hospital mortality rates were 1.84 and 1.64 times higher from 6 November 2020 to 15 January 2021, the alpha variant, and in negative correlation with gastrointestinal symptoms.

Comparing Coronavirus Disease 2019 (COVID-19) Pandemic Waves in Hospitalized Patients: A Retrospective, Multicenter, Cohort Study.

BACKGROUND: Coronavirus disease 2019 was first diagnosed in Israel at the end of February 2020. By the end of June 2021, there were 842 536 confirmed cases and 6428 deaths. Our aim in this multicenter, retrospective, cohort study is to describe the demographic and clinical characteristics of hospitalized patients and compare the pandemic waves before immunization. METHODS: Of 22 302 patients hospitalized in general medical centers, we randomly selected 6329 for the study. Of these, 3582 and 1106 were eligible for the study in the first period (first and second waves) and in the second period (third wave), respectively. RESULTS: Thirty-day mortality was higher in the second period than in the first period, 25.20% vs 13.68% (P < .001). Invasive mechanical ventilation supported 9.19% and 14.21% of patients in the first period and second period, respectively. Extracorporeal membrane oxygenation (ECMO) was used more than twice as often in the second period. CONCLUSIONS: Invasive ventilation, use of ECMO, and mortality rate were 1.5 to 2 times higher in the second period than in the first period. In the second period, patients had a more severe presentation and higher mortality than those in the first period.

Comparative Effectiveness of Multiple Different First-Line Treatment Regimens for Helicobacter pylori Infection: A Network Meta-analysis.

BACKGROUND & AIMS: A number of double, triple, and quadruple therapies have been proposed as first-line empiric treatments for Helicobacter pylori infection. However, knowledge of their worldwide and regional comparative efficacy is lacking. We examined the comparative effectiveness of all empirically used first-line regimens tested against standard triple treatment using a network meta-analysis of published randomized controlled trials. METHODS: Data extracted from eligible randomized controlled trials were entered into a Bayesian network meta-analysis to investigate the comparative efficacy of H pylori infection empiric first-line regimens and to explore their effectiveness rank order. The ranking probability for each regimen was evaluated by means of surfaces under cumulative ranking values. RESULTS: Sixty-eight eligible randomized controlled trials were included, giving a total of 92 paired comparisons with 22,975 patients randomized to 8 first-line regimens. The overall results showed that only vonoprazan triple therapy and reverse hybrid therapy achieved cure rates of >90%. Levofloxacin triple therapy performed best in Western countries (eradication rate 88.5%). The comparative effectiveness ranking showed that vonoprazan triple therapy had the best results, whereas standard triple therapy was the least efficacious regimen (surfaces under cumulative ranking 92.4% vs 4.7% respectively; odds ratio, 3.80; 95% credible interval, 1.62-8.94). CONCLUSIONS: For first-line empiric treatment of H pylori infection, vonoprazan triple therapy and reverse hybrid therapy achieved high eradication rates of >90%. Levofloxacin triple therapy achieved the highest eradication rates in Western countries. Standard triple therapy was the least efficacious regimen in this network meta-analysis.

Empirical Second-Line Therapy in 5000 Patients of the European Registry on Helicobacter pylori Management (Hp-EuReg).

BACKGROUND & AIMS: After a first Helicobacter pylori eradication attempt, approximately 20% of patients will remain infected. The aim of the current study was to assess the effectiveness and safety of second-line empiric treatment in Europe. METHODS: This international, multicenter, prospective, non-interventional registry aimed to evaluate the decisions and outcomes of H pylori management by European gastroenterologists. All infected adult cases with a previous eradication treatment attempt were registered with the Spanish Association of Gastroenterology-Research Electronic Data Capture until February 2021. Patients allergic to penicillin and those who received susceptibility-guided therapy were excluded. Data monitoring was performed to ensure data quality. RESULTS: Overall, 5055 patients received empiric second-line treatment. Triple therapy with amoxicillin and levofloxacin was prescribed most commonly (33%). The overall effectiveness was 82% by modified intention-to-treat analysis and 83% in the per-protocol population. After failure of first-line clarithromycin-containing treatment, optimal eradication (>90%) was obtained with moxifloxacin-containing triple therapy or levofloxacin-containing quadruple therapy (with bismuth). In patients receiving triple therapy containing levofloxacin or moxifloxacin, and levofloxacin-bismuth quadruple treatment, cure rates were optimized with 14-day regimens using high doses of proton pump inhibitors. However, 3-in-1 single capsule or levofloxacin-bismuth quadruple therapy produced reliable eradication rates regardless of proton pump inhibitor dose, duration of therapy, or previous first-line treatment. The overall incidence of adverse events was 28%, and most (85%) were mild. Three patients developed serious adverse events (0.3%) requiring hospitalization. CONCLUSIONS: Empiric second-line regimens including 14-day quinolone triple therapies, 14-day levofloxacin-bismuth quadruple therapy, 14-day tetracycline-bismuth classic quadruple therapy, and 10-day bismuth quadruple therapy (as a single capsule) provided optimal effectiveness. However, many other second-line treatments evaluated reported low eradication rates. ClincialTrials.gov number: NCT02328131.

COVID-19 and Renal Failure - Adding Insult to Injury? Israel's Experience Based on Nationwide Retrospective Cohort Study.

INTRODUCTION: Renal failure (RF) is a risk factor for mortality among hospitalized patients. However, its role in COVID-19-related morbidity and mortality is inconclusive. The aim of the study was to determine whether RF is a significant predictor of clinical outcomes in COVID-19 hospitalized patients based on a retrospective, nationwide, cohort study. METHODS: The study sample consisted of patients hospitalized in Israel for COVID-19 in two periods. A random sample of these admissions was selected, and experienced nurses extracted the data from the electronic files. The group with RF on admission was compared to the group of patients without RF. The association of RF with 30-day mortality was investigated using a logistic regression model. RESULTS: During the two periods, 19,308 and 2994 patients were admitted, from which a random sample of 4688 patients was extracted. The 30-day mortality rate for patients with RF was 30% (95% confidence interval (CI): 27-33%) compared to 8% (95% CI: 7-9%) among patients without RF. The estimated OR for 30-day mortality among RF versus other patients was 4.3 (95% CI: 3.7-5.1) and after adjustment for confounders was 2.2 (95% CI: 1.8-2.6). Furthermore, RF patients received treatment by vasopressors and invasive mechanical ventilation (IMV) more frequently than those without RF (vasopressors: 17% versus 6%, OR = 2.8, p<0.0001; IMV: 17% versus 7%, OR = 2.6, p<0.0001). DISCUSSION: RF is an independent risk factor for mortality, IMV, and the need for vasopressors among patients hospitalized for COVID-19 infection. Therefore, this condition requires special attention when considering preventive tools, monitoring, and treatment.

Accessing unproven interventions in the COVID-19 pandemic: discussion on the ethics of 'compassionate therapies' in times of catastrophic pandemics.

Since the onset of the SARS-CoV-2 pandemic, an array of off-label interventions has been used to treat patients, either provided as compassionate care or tested in clinical trials. There is a challenge in determining the justification for conducting randomised controlled trials over providing compassionate use in an emergency setting. A rapid and more accurate evaluation tool is needed to assess the effect of these treatments. Given the similarity to the Ebola Virus Disease (EVD) pandemic in Africa in 2014, we suggest using a tool designed by the WHO committee in the aftermath of the EVD pandemic: Monitored Emergency Use of Unregistered and Investigational Interventions (MEURI). Considering the uncertainty around SARS-CoV-2, we propose using an improved MEURI including the Plan-Do-Study-Act tool. This combined tool may facilitate dynamic monitoring, analysing, re-evaluating and re-authorising emergency use of unproven treatments and repeat it in cycles. It will enable adjustment and application of outcomes to clinical practice according to changing circumstances and increase the production of valuable data to promote the best standard of care and high-quality research-even during a pandemic.

[DEVELOPMENT AND IMPROVEMENT OF THE NATIONAL PLAN FOR QUALITY INDICATORS - COMPARISON OF 2016 AND 2020 RESULTS].

INTRODUCTION: The National Plan for Quality Indicators of hospitals was established in 2012. The aim of the plan was to improve and advance the quality of medical treatment by measuring, comparison of hospitals and publication of the achievements to the public. Aims: To evaluate and compare the quality indicators between 2016 and 2020, characterize the different types and their contribution to the quality of patient care. METHODS: We calculated the proportion of indicators in every category and medical fields. These data were compared between 2016 and 2020 with Chi-squared tests using SAS software. We compared the success of hospitals over this period over 25 indicators shared by them, when details of the numerator and denominator were available. RESULTS: No significant changes were found in the relative portion of cardiology and pediatrics indicators. An increase was demonstrated in obstetrics, neonatology and psychiatry, and a decrease in neurology, geriatrics and surgery. An increase was also found in result indicators, communication and coordination and in public health. The success rate was higher in 2020 with an increase of 26%. In only 2 indicators, measurement of head circumference in neonates and nutritional assessment in chronic ventilated patients, the success rate was lower in 2020, probably due to significant increase in their required aims and the corona pandemic. CONCLUSIONS: The success rate of the quality indicators was significantly higher in 2020 in spite of an annual increase in their aims. Continuous refreshment of the national plan and the addition of safety indicators to the national plan will bring improvement in the quality and safety of patient care.

[CONFIDENTIALITY OF ADVERSE EVENTS INVESTIGATIONS - THE PRESENT STATUS AND WHAT IS NEEDED].

INTRODUCTION: The goal of the medical staff is to provide proper, effective and efficient treatment to the patient and to take care of his well-being. An error in medical care that causes a serious outcome or mortality, can be considered negligence when the caregiver did not meet the requirements of a reasonable physician for reasonable care and did not take the necessary precautions in providing the treatment, in light of the information available to him. The perception of punishment and compensation due to harm, caused to a patient as a result of a medical error, changed dramatically over the years. Starting with direct and severe punishment according to Hammurabi laws and ending with the "no fault" approach that is accepted widely in some countries. Following an adverse event that occurred in medical treatment, a process should be conducted in order to draw lessons to reduce the likelihood of recurrence of similar incidents in the future, by answering 4 questions: What happened? How did it happen? Why did it happen? and What should be done to prevent similar incidents in the future? The Patient Rights Act does not suggest conducting a safety investigation but recommends an examination board in cases of negligence or error in treatment. By law, the protocols of the examination board are confidential and can be removed by the court in case the protocol contains evidence of importance that is unlikely to be found in the medical record. Lack of confidentiality may cause medical staff to be reluctant of conducting a safety investigation due to fear of using its findings for a lawsuit or appointing an examination board whose conclusions will be reported to the victim and his family. The "no fault" method overcomes these barriers by enabling a thorough safety investigation and has important professional, economic and social aspects with a direct impact on the quality and safety of treatment. The method expands the accessibility of victims to compensation, reduces the number of claims and the burden on the courts. Among additional benefits are transparency and consistency in decisions, promoting patient safety due to physicians' willingness to report failures, reduction in "defensive medicine" and spending in the health care system.

European Registry on Helicobacter pylori management (Hp-EuReg): patterns and trends in first-line empirical eradication prescription and outcomes of 5 years and 21 533 patients.

OBJECTIVE: The best approach for Helicobacter pylori management remains unclear. An audit process is essential to ensure clinical practice is aligned with best standards of care. DESIGN: International multicentre prospective non-interventional registry starting in 2013 aimed to evaluate the decisions and outcomes in H. pylori management by European gastroenterologists. Patients were registered in an e-CRF by AEG-REDCap. Variables included demographics, previous eradication attempts, prescribed treatment, adverse events and outcomes. Data monitoring was performed to ensure data quality. Time-trend and geographical analyses were performed. RESULTS: 30 394 patients from 27 European countries were evaluated and 21 533 (78%) first-line empirical H. pylori treatments were included for analysis. Pretreatment resistance rates were 23% to clarithromycin, 32% to metronidazole and 13% to both. Triple therapy with amoxicillin and clarithromycin was most commonly prescribed (39%), achieving 81.5% modified intention-to-treat eradication rate. Over 90% eradication was obtained only with 10-day bismuth quadruple or 14-day concomitant treatments. Longer treatment duration, higher acid inhibition and compliance were associated with higher eradication rates. Time-trend analysis showed a region-dependent shift in prescriptions including abandoning triple therapies, using higher acid-inhibition and longer treatments, which was associated with an overall effectiveness increase (84%-90%). CONCLUSION: Management of H. pylori infection by European gastroenterologists is heterogeneous, suboptimal and discrepant with current recommendations. Only quadruple therapies lasting at least 10 days are able to achieve over 90% eradication rates. European recommendations are being slowly and heterogeneously incorporated into routine clinical practice, which was associated with a corresponding increase in effectiveness.

Association Between Polyp Detection Rate and Post-Colonoscopy Cancer Among Patients Undergoing Diagnostic Colonoscopy.

Postcolonoscopy colorectal cancer (PCCRC) can arise from missed cancers, missed premalignant lesions, incomplete resection, and new cancers with an accelerated route to cancer.1.

A Network Meta-Analysis of Randomized Controlled Trials on the Treatment of Eosinophilic Esophagitis in Adults and Children.

BACKGROUND: Network meta-analysis is used as a data synthesizer, incorporating direct and indirect evidence about treatments in a series of randomized control trials. OBJECTIVE: To evaluate the comparative efficacy of various treatments for eosinophilic esophagitis (EoE). METHODS: We performed a network meta-analysis to combine direct and indirect data to investigate the efficiency of drug therapies, which were evaluated in relevant randomized control trials for EoE. RESULTS: Seventeen eligible studies (14 two-arm and 3 multiple-arm) were introduced to the meta-analysis. A total of 1011 patients were included, in whom 15 therapeutic interventions were used, namely: (1) budesonide oral suspension, (2) budesonide 1 mg orodispersible tablet twice daily, (3) budesonide 2 mg orodispersible tablet twice daily, (4) esomeprazole, (5) fluticasone, (6) nebulized steroid, (7) placebo, (8) prednisone, (9) anti-IL-5-mab (mepolizumab), (10) anti-IL-5-mab [reslizumab(1), ie, 1 mg/kg], (11) anti-IL-5-mab [reslizumab(2), ie, 2 mg/kg], (12) anti-IL-5-mab [reslizumab(3), ie, 3 mg/kg], (13) anti-IL-13-mab (QAX 576), (14) anti-IL-13-mab [RCP 4046 (180)], and (15) anti-IL-13-mab [RCP 4046 (360)]. Budesonide 1 mg orodispersible tablet twice daily showed the highest efficacy (SUCRA 0.91), whereas placebo was the least effective. In adult patients budesonide 1 mg orodispersible tablet twice daily remained the optimal treatment approach, whereas the corresponding therapeutic approach in pediatric patients was fluticasone. CONCLUSIONS: This meta-analysis showed that budesonide 1 mg orodispersible tablet twice daily was the best treatment for EoE, as it was the most effective. This treatment remained the optimal approach in adult patients, whereas fluticasone was the best treatment in pediatric patients.

Mucin Secretion in Cystic Fibrosis: A Systematic Review.

BACKGROUND: Mucus protects the epithelium against invaders and toxic materials. Sticky and thick mucus is characteristic of CF. OBJECTIVE: The aim of this systematic review is to characterize the specific mucins secreted in the lung and intestinal tract of CF patients. METHODS: A systematic literature search was conducted up to December 31, 2019. The following terms were used: "cystic fibrosis" AND "mucin." Case-control studies comparing mucin expression in CF patients to healthy controls were included. RESULTS: We found 741 eligible studies, 694 studies were rejected because they were performed in animals and not in full text, and 32 studies were excluded being editorials, duplications, review articles, meta-analysis, or not in English. Fifteen studies were eligible for our study, including 150 CF patients compared to 82 healthy controls, all fulfilled the inclusion criteria. The main mucin types expressed in the sinus submucosal glands, sputum, tracheobronchial surface epithelium, and lung submucosal glands were MUC5AC and MUC5B. Increase in the number of sinusoidal submucosal glands and expression of MUC5B was found in CF patients, but no such difference from healthy controls was found for the number of goblet cells in the surface epithelium nor in the expression of -MUC5AC. The opposite was found in the tracheobronchial surface epithelium and in the lungs. CONCLUSIONS: Increased expression of MUC5AC in the surface epithelium and of MUC5B in the subepithelial glands may be the result of higher secretion rate of mucin into the lumen of the respiratory tract, causing mucus plaque, infection, and inflammation.

Susceptibility-guided versus empirical treatment for Helicobacter pylori infection: A systematic review and meta-analysis.

BACKGROUND AND AIM: Empirical therapy for Helicobacter pylori infection is limited by increasing antibiotic resistance and suboptimal eradication rates. Studies of the relative effectiveness of susceptibility-guided therapy have produced conflicting results. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to determine whether susceptibility-guided therapy is superior to empirical therapy for H. pylori infection. METHODS: We searched articles listed in PubMed, MEDLINE, EMBASE, and Web of Science through May 25, 2020, RCTs comparing susceptibility-guided versus empirical therapy for H. pylori infection. Outcomes, including effectiveness and safety, were analyzed in a meta-analysis. RESULTS: Our final analysis included 16 studies, comprising 2374 patients who received susceptibility-guided therapy and 2451 patients who received empirical treatment. In previously untreated subjects, susceptibility-guided therapy was slightly more effective than empirical therapy (intent to treat risk ratio [RR], 1.14; 95% confidence interval [CI], 1.07-1.21; P < 0.0001, I2  = 75%). Susceptibility-guided therapy was superior to first-line clarithromycin-based triple therapy only when clarithromycin resistance exceeded 20% (RR, 1.18; 95% CI, 1.07-1.30; P = 0.001, I2  = 81%). Susceptibility-guided therapy was not more effective than empirical quadruple therapy (RR, 1.02; 95% CI, 0.92-1.13; P = 0.759, I2  = 80%). Three RCTs were performed exclusively among previously treated subjects, and were highly heterogeneous. CONCLUSIONS: Our findings suggest that susceptibility-guided treatment may be slightly superior to empirical first line triple therapy. Susceptibility- guided treatment does not appear to be superior to empirical first-line quadruple therapy or empirical rescue therapy.

Rifabutin triple therapy for first-line and rescue treatment of Helicobacter pylori infection: A systematic review and meta-analysis.

BACKGROUND AND AIM: Due to the increasing resistance of Helicobacter pylori, there is a need for novel antibiotic treatment protocols. We aimed to perform a systematic review and meta-analysis in order to determine the effectiveness and safety of rifabutin triple therapy for H. pylori infection. METHODS: We performed a systematic review of prospective clinical trials with a treatment arm consisting of proton pump inhibitor, amoxicillin, and rifabutin and a meta-analysis of randomized controlled trials (RCTs). RESULTS: Thirty-three prospective studies including 44 datasets were identified. Meta-analysis of four RCTs for rescue treatment found no difference between treatment groups (odds ratio [OR] 0.88, 95% confidence interval [CI] 0.437-1.791, I2  = 68.1%, P = 0.733). Only one RCT compared rifabutin therapy with control for first-line treatment of H. pylori infection (OR 3.78, 95% CI 2.44-5.87, P < 0.0001). Treatment was more likely to be successful in Asian versus non-Asian populations (81.0% vs 72.4%, P = 0.001) and when daily amoxicillin dose was ≥ 3000 mg or proton pump inhibitor dose was ≥ 80 mg or treatment duration was 14 days (80.6% vs 66.0%, P = 0.0001). The overall event rate for adverse effects was 24.8% (729/2937) (95% CI 0.23-0.26), and the pooled OR for adverse effects in the treatment versus control group was 0.93 (95% CI 0.50-1.75) (I2  = 79.76, P = 0.82). CONCLUSION: Evidence for the effectiveness of rifabutin for the first-line treatment of H. pylori infection in adults is limited, and studies comparing rifabutin with conventional first-line treatments are lacking.

Hospitalization of Patients with Ulcerative Colitis: A Systematic Review and Meta-Analysis.

BACKGROUND: Hospitalization of ulcerative colitis patients is needed in severe exacerbation of the disease or for managing complications. In this systematic review and meta-analysis the prevalence of hospitalization in ulcerative colitis and possible predictive factors are discussed. A systematic literature search of English language publications that were published before 31 December 2019 was conducted. Retrospective cohort studies describing hospitalizations of UC patients were included. Meta-analysis was performed by using comprehensive meta-analysis software. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated for the number of patients hospitalized. Seven studies and 15 datasets were found that fulfilled the inclusion criteria. In total, the studies included 2067 patients from six countries. The event rates for the number of patients hospitalized in a follow-up duration of 42,320 patient-years and for the number of patients underwent operation in a follow-up of 24,650 patient-years were 0.065 (95%CI 0.063-0.068) and 0.019 (95%CI 0.017-0.021), respectively. More studies during the era of biologics need to be performed to identify the factors predictive of hospitalization and surgery with UC. Prevention of inflammation and UC complications may prevent hospitalization and the need for surgical treatment.

Performing Duplex within 72 Hours of Transient Ischemic Attack May Decrease Mortality, the Israeli National Program for Quality Indicators experience.

BACKGROUND: With diagnostic imaging, such as a duplex of the carotid arteries, finding of stenosis and atherosclerotic plaque and consequent end arterectomy may be important for decreasing the danger of developing cerebrovascular accident after transient ischemic attack (TIA). OBJECTIVES: To measure performance rates of duplex of carotid arteries within 72 hours of TIA diagnosis. METHODS: The denominator included all patients who were admitted to emergency departments because of TIA, and the numerator included those who underwent duplex within 72 hours of admission. Inclusion criteria included all patients older than 18 years who were admitted because of TIA according to the ICD9 codes. RESULTS: Measuring this indicator started in 2015 with 5504 patients and a 58% success rate. The figures for the years 2016, 2017, and 2018 were 5309, 5447, and 5278 patients with success rates of 73%, 79%, and 83%, respectively. Six of 26 hospitals (23.0%) reached the target of 80% in 2018. From 2015 to 2018 a total of 21,538 patients were admitted to emergency departments in Israel and diagnosed with TIA. Of these, 15,722 (72.9%) underwent duplex within 72 hours. The mortality rate within 30 days from diagnosis was 0.81% in patients who performed duplex within 72 hours of diagnosis and 2.37% in patients who did not, odds ratio 2.676, 95% confidence interval 2.051-3.492, P < 0.0001. These results indicate a statistically significant decrease of 65.82. CONCLUSIONS: A significant decrease in mortality was noted in patients with a new diagnosis of TIA who underwent duplex within 72 hours of diagnosis.

European Registry on Helicobacter pylori management (Hp-EuReg): First-line Therapy in Israel.

BACKGROUND: The antibiotic resistance profile of Helicobacter pylori (H. pylori) is constantly changing. Up-to-date and reliable data for the effectiveness of first-line H. pylori treatment protocols are necessary to provide evidence-based best-practice guidelines. OBJECTIVES: To determine the effectiveness, compliance and safety of first-line treatment for H. pylori in Israel. METHODS: An observational, prospective, multicenter study was conducted in tertiary referral centers in Israel, as part of the European registry on H. pylori management (Hp-EuReg). H. pylori-infected patients were included from 2013 to March 2020. Data collected included demographics, clinical data, diagnostic tests, previous eradication attempts, current treatment, compliance, adverse events, and treatment outcome result. RESULTS: In total, 242 patients were registered, including 121 (50%) who received first-line therapy, 41% of these individuals received clarithromycin based triple therapy and 58.9% received a four-drug regimen. The overall effectiveness of first-line therapy was 85% and 86% by modified intention-to-treat and per protocol analyses, respectively. The effectiveness of both sequential and concomitant therapies was 100% while clarithromycin-based triple therapy achieved an eradication rate of 79%. Treatment eradication was higher among patients who received high dose proton pump inhibitor (PPI) compared to those treated with low dose PPI (100% vs. 81.5% respectively, P < 0.01). No difference in treatment effectiveness was found between 7-, 10-, and 14-day treatment. CONCLUSIONS: The effectiveness of clarithromycin-based triple therapy is suboptimal. First-line treatment of H. pylori infection should consist of four drugs, including high dose PPI, according to international guidelines.
