Assessment of Predictors for SARS-CoV-2 Antibodies Decline Rate in Health Care Workers after BNT162b2 Vaccination-Results from a Serological Survey.

Background: SARS-CoV-2 is a novel human pathogen causing Coronavirus Disease 2019 that has caused widespread global mortality and morbidity. Since health workers in Israel were among the first to be vaccinated, we had a unique opportunity to investigate the post-vaccination level of IgG anti-S levels antibodies (Abs) and their dynamics by demographic and professional factors. Methods: Prospective Serological Survey during December 2020−August 2021 at Barzilai Medical Center among 458 health care workers (HCW) followed for 6 months after the second BNT162b2 vaccine dose.

Workplace Violence against Hospital Workers during the COVID-19 Pandemic in Israel: Implications for Public Health.

Workplace violence (WPV) against healthcare workers, a serious public health problem with profound implications, has worsened during the COVID-19 pandemic. This study examined the incidence of different types of WPV in a public hospital in Israel during the pandemic and analyzes the factors associated with its occurrence. A cross-sectional study was performed via an online questionnaire with 486 workers at a government hospital in Israel.

Elapsed time since BNT162b2 vaccine and risk of SARS-CoV-2 infection: test negative design study.

Objectives: To determine whether time elapsed since the second injection of the Pfizer-BioNTech BNT162b2 mRNA vaccine was significantly associated with the risk of covid-19 infection after vaccination in people who received two vaccine injections.

Design: Test negative design study.

Setting: Electronic health records of a large state mandated healthcare organisation, Israel.

Biomarkers in Hereditary Angioedema.

A biomarker is a defined characteristic measured as an indicator of normal, biologic, pathogenic processes, or biological responses to an exposure or intervention. Diagnostic biomarkers are used to detect a disease or a subtype of a disease; monitoring biomarkers are measured serially to assess a medical condition; response biomarkers are used to check biologic response following a medical intervention; predictive biomarkers are used to identify patients who are more likely to respond to a medical intervention; and prognostic biomarkers are used to assess the future likelihood of a clinical event. Although biomarkers have been extensively investigated and validated in many diseases and pathologies, very few are currently useful for the diagnosis, evaluation of disease activity, and treatment of hereditary angioedema (HAE).

Association between cervical disc disease and lesions of multiple sclerosis.

Background: Cervical discopathy and demyelinating lesions often co-exist in patients with multiple sclerosis (MS). Our study examines the possible association between these two pathologies.

Methods: Medical records and cervical magnetic resonance imaging scans of MS patients with cervical discopathy who were seen at our MS clinic during 2018 were retrospectively reviewed.
