Anti-Tetanus Vaccination Is Associated with Reduced Occurrence and Slower Progression of Parkinson's Disease-A Retrospective Study.

Parkinson's disease (PD) is a neurodegenerative disorder that progressively damages the autonomic and central nervous systems, leading to hallmark symptoms such as resting tremor, bradykinesia, and rigidity. Despite extensive research, the underlying cause of PD remains unclear, and current treatments are unable to halt the progression of the disease. In this retrospective study, based on historical electronic health records (EHR) from a national health provider covering the period from 2003 to 2023, we investigated the impact of vaccination and medication purchases on PD occurrence and severity.

Health disparities in diabetes treatment: The challenge of G6PD deficiency.

Aims: To assess the impact of Glucose-6-phosphate dehydrogenase (G6PD) deficiency, an enzymatic deficiency prevalent in individuals of African or Asian descent, on Hemoglobin A1c (HbA1c) levels, diabetes medication purchases, and the cumulative incidence of diabetes related complications.

Methods: A large cohort study was conducted within a national health organization, comparing 3,913 G6PD-deficient patients to a matched control group without G6PD deficiency over two decades. The main measures and outcomes were the HbA1c levels, patterns of diabetes medication purchases, and the incidence of severe diabetes-related complications.

Comparative Analysis of Inflammatory Bowel Disease Management: Hospital-based Versus Community-based Care.

Background: Inflammatory bowel disease (IBD) encompasses chronic gastrointestinal disorders characterized by recurrent inflammation. Achieving mucosal healing and preventing disease progression are primary treatment goals.

Objectives: This study aimed to compare disease characteristics, medication utilization, procedures performed, and hospitalizations between IBD patients treated in hospital and community settings using the Leumit Health Service database.

Identifying Diabetes Related-Complications in a Real-World Free-Text Electronic Medical Records in Hebrew Using Natural Language Processing Techniques.

Background: Studies have demonstrated that 50% to 80% of patients do not receive an International Classification of Diseases (ICD) code assigned to their medical encounter or condition. For these patients, their clinical information is mostly recorded as unstructured free-text narrative data in the medical record without standardized coding or extraction of structured data elements. Leumit Health Services (LHS) in collaboration with the Israeli Ministry of Health (MoH) conducted this study using electronic medical records (EMRs) to systematically extract meaningful clinical information about people with diabetes from the unstructured free-text notes.

Glucose-6-phosphate dehydrogenase deficiency and long-term risk of immune-related disorders.

Introduction: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked enzymatic disorder that is particularly prevalent in Africa, Asia, and the Middle East. This study aimed to assess the long-term health risks associated with G6PD deficiency.

Methods: A retrospective cohort study was conducted using data from a national healthcare provider in Israel (Leumit Health Services).

Glucose-6-Phosphate Dehydrogenase Deficiency and Coronavirus Disease 2019.

In this cohort study conducted in a national healthcare organization in Israel, we found that individuals with glucose-6-phosphate dehydrogenase deficiency had an increased risk of coronavirus disease 2019 (COVID-19) infection and severity, with higher rates of hospitalization and diagnosed long COVID.

A comparative study of chronic spontaneous urticaria and chronic mast cell mediated angioedema.

Mast cell-mediated angioedema (MC-AE) is considered a form of chronic spontaneous urticaria (CSU). To investigate the clinical and laboratory features that distinguish MC-AE from antihistamine-responsive CSU (CSU), and antihistamine-resistant CSU (R-CSU) with and without concomitant AE. A retrospective observational study using the electronic patient record data base of patients with MC-AE, CSU, R-CSU, and sex- and age-matched control group (control), with a case-control ratio of 1:2.

Can the Norton Scale Score Be Used as an Adjunct Tool for Implantable Defibrillator Patient Selection? A Retrospective Single-Center Cohort Study.

(1) Background: Implantable cardioverter defibrillators (ICDs) have become the standard of care in the prevention of sudden cardiac death, yet studies have shown that competing causes of death may limit ICD benefits. The Norton scale is a pressure ulcer risk score shown to have prognostic value in other fields. The purpose of this study was to assess the use of the Norton scale as an aid for ICD patient selection; (2) Methods: The study was comprised of consecutive patients who underwent defibrillator implantation at Sheba Medical Center between 2008 and 2016.

Real-world hepatitis B antiviral treatment trends and adherence to practice guidelines: a large cohort study.

Background: Epidemiologic data regarding chronic hepatitis B virus infections in Israel is limited as extensive population-based studies have not been performed.

Objective: This work aimed to evaluate the current characteristics of hepatitis B infection among Israeli adults and evaluate adherence to the European Association for the Study of the Liver practice guidelines for antiviral treatment.

Methods: Clinical and demographic data of HBsAg-positive patients registered in the Leumit-Health-Service database (one of the four major health maintenance organizations in Israel) between 2000 and 2019 were retrieved.

Clinical and Laboratory Features in the Israeli Population with COVID-19 Infection after Pfizer-BioNTech mRNA Booster Vaccination.

Background: Immune protection following either vaccination or infection with SARS-CoV-2 decreases over time. Objective: We aim to describe clinical and sociodemographic characteristics associated with COVID-19 infection at least 14 days after booster vaccination in the Israeli population. Methods: We conducted a population-based study among adult members of Leumit Health Services (LHS) in Israel.

Large-Scale Study of Antibody Titer Decay following BNT162b2 mRNA Vaccine or SARS-CoV-2 Infection.

Immune protection following either vaccination or infection with SARS-CoV-2 is thought to decrease over time. We designed a retrospective study, conducted at Leumit Health Services in Israel, to determine the kinetics of SARS-CoV-2 IgG antibodies following administration of two doses of BNT162b2 vaccine, or SARS-CoV-2 infection in unvaccinated individuals. Antibody titers were measured between 31 January 2021, and 31 July 2021 in two mutually exclusive groups: (i) vaccinated individuals who received two doses of BNT162b2 vaccine and had no history of previous infection with COVID-19 and (ii) SARS-CoV-2 convalescents who had not received the vaccine.

Chronic spontaneous urticaria after BNT162b2 mRNA (Pfizer-BioNTech) vaccination against SARS-CoV-2.

The factors that trigger and exacerbate chronic spontaneous urticaria (CSU) are well known, but it is not unclear whether messenger RNA (mRNA) vaccination against severe acute respiratory syndrome coronavirus 2 can trigger new cases of CSU or a relapse of CSU after long-term remission. To study the clinical cases of patients with new-onset CSU and CSU in remission who relapsed within 3 months after BNT162b2 mRNA vaccination. All patients with a CSU diagnosis within 12 weeks of BNT162b2 mRNA vaccination were retrospectively identified and included in the new-onset CSU and the relapsed CSU groups.

Large-scale study of antibody titer decay following BNT162b2 mRNA vaccine or SARS-CoV-2 infection.

Background: Immune protection following either vaccination or infection with SARS-CoV-2 decreases over time.

Objective: To determine the kinetics of SARS-CoV-2 IgG antibodies following administration of two doses of BNT162b2 vaccine, or SARS-CoV-2 infection in unvaccinated individuals.

Methods: Antibody titers were measured between January 31, 2021, and July 31, 2021 in two mutually exclusive groups: i) vaccinated individuals who received two doses of BNT162b2 vaccine and had no history of previous infection with COVID-19 and ii) SARS-CoV-2 convalescents who had not received the vaccine.

Elapsed time since BNT162b2 vaccine and risk of SARS-CoV-2 infection in a large cohort.

Importance: Israel was among the first countries to launch a large-scale COVID-19 vaccination campaign, and quickly vaccinated its population, achieving early control over the spread of the virus. However, the number of COVID-19 cases is now rapidly increasing, which may indicate that vaccine protection decreases over time.

Objective: To determine whether time elapsed since the second BNT162b2 messenger RNA (mRNA) vaccine (Pfizer-BioNTech) injection is significantly associated with the risk of post-vaccination COVID-19 infection.
