: The impact of the COVID-19 pandemic on the incidence rate of childhood type 1 diabetes (T1D) is controversial. Our aim was to analyze the incidence of new-onset T1D among children aged 0-17 before and during the COVID-19 pandemic in Israel. : Data obtained from the national T1D registry for children aged 0-17 were analyzed for the pre-pandemic (1997-2019) and pandemic (2020-2022) periods.

Methods: Data was extracted from several national registries. The study period was March 1, 2020-March 31, 2022.
Children and adolescents with early onset autoimmune diseases have a different seasonality of month of birth than the general population. This pattern is consistent with an infection during pregnancy affecting the fetus or an infection immediately after birth that act as early triggers of the autoimmune diseases. We present data supporting the use of Rotavirus vaccinations in the reduction of incidence of childhood T1D and propose further investigations into whether other anti-virus vaccinations may reduce the burden of other autoimmune diseases such as multiple sclerosis, atopic dermatitis, psoriasis and subtypes of rheumatoid arthritis, Hashimoto thyroiditis.

- The study confirmed that the Society of Thoracic Surgeons predicted risk of mortality score (PROM) is effective in predicting long-term survival in Israeli cardiac surgery patients, building on prior findings for 30-day mortality.
- Data from 1279 patients was analyzed over a follow-up period averaging 62 months, revealing that higher PROM scores were linked to significantly reduced survival rates.
- Key factors influencing long-term mortality included advanced age, lower heart function (ejection fraction), need for reoperations, and health conditions like diabetes and kidney dialysis, indicating PROM's utility in surgical decision-making.
Background: End-stage renal disease (ESRD) has been shown to be associated with increased mortality in patients undergoing cardiac surgery. We aimed to compare the short- and mid-term mortality after cardiac surgery of patients with dialysis-dependent ESRD (DD-ESRD) to patients with normal renal function (NRF), using national registries: the ESRD registry, the adult cardiac surgery registry (ACSR), and the National Mortality Registry.
Methods: The study population comprised 8207 adult patients who underwent either isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR), isolated mitral valve replacement (MVR), or CABG + valve-related procedure, between January 2017 and April 2019.
