Nirmatrelvir-ritonavir was granted emergency use authorization in Israel in January 2022 to treat high-risk patients with mild-to-moderate COVID-19. The aim of the study was to assess the association between nirmatrelvir-ritonavir treatment and COVID-19-related hospitalization and healthcare resource utilization (HCRU) in a country with a high level of vaccinations compared to patients who were offered treatment and declined. The Maccabi Healthcare Services dataset was used to identify high-risk SARS-CoV-2-positive adults from January to February 2022 who received nirmatrelvir-ritonavir within 5 days of symptom onset (treatment group) or who were offered nirmatrelvir-ritonavir treatment and declined it (reference group).

A recent genome-wide association study focusing on Jewish Ashkenazi high risk women identified a novel locus on chromosome 6 as putatively containing breast cancer susceptibility genes, a locus that contains two seemingly novel candidate genes: RNF146 and ECHDC1. To further explore the role of these two genes in inherited predisposition to breast cancer.

Family-specific pathogenic mutations in both genes can be detected in up to 5% of high risk Ashkenazim. The contribution of major gene rearrangements and seemingly pathogenic missense mutations to inherited breast cancer predisposition has never been systematically evaluated in Ashkenazim.

The MDM2 protein is an ubiquitin ligase that plays a critical role in regulating the levels and activity of the p53 protein, which is a central tumor suppressor. A SNP in the human MDM2 gene (SNP309 T/G) occurs at frequencies dependent on demographic history and has been shown to have important differential effects on the activity of the MDM2 and p53 proteins and to associate with altered risk for the development of several cancers. In this report, the haplotype structure of the MDM2 gene is determined by using 14 different SNPs across the gene from three different population samples: Caucasians, African Americans, and the Ashkenazi Jewish ethnic group.

Two BRCA1 mutations (P1812A, P25T), and a BRCA2 mutation (5164del4) have been detected in NAJ high-risk families. We studied the prevalence of these three mutations in 270 high-risk NAJ families, including 85 from Iraq/Iran, 67 from North Africa, 27 from Yemen, 50 from the Balkan region, and 41 with mixed ancestry.
