Identification and characterization of 122 novel HLA alleles in bone marrow donors recruited to the Ezer Mizion Bone Marrow Donor Registry.

Between January 2018 and June 2021, the Ezer Mizion recruited 223,960 donors. All donors were typed for their HLA class I and II alleles at high resolution by Next Generation Sequencing techniques. Comparison between the sequences obtained from these donors and those in the IPD-IMGT/HLA Database, revealed 122 Novel HLA alleles that were found in 133 donors. Most of the alleles, 94 (77%) were identified in the HLA class I genes (30, 35, and 29 in HLA-A, -B, and -C, respectively), and 28 (23%) were detected in the HLA class II genes (9 in HLA-DRB1 and -DQB1 and 10 in -DPB1). Most of these novel alleles, 106 (86.9%) comprised single nucleotide variation (SNV), 9 (7.4%) present multiple amino acids variation, 4 and 3 were generated because of deletions and insertions, respectively. Ten of these novel alleles were seen to be null alleles.

Perinatal depressive symptoms among Arab women in northern Israel.

Perinatal depression, a prevalent condition with negative consequences for the mother, infant and family, has been reported in many countries. This study aimed to assess the scope of depressive symptoms among pregnant and postnatal Israeli Arab women and to identify possible risk factors. Data were collected from a screening program at 58 Mother-Child Health Care clinics in northern Israel from June to December, 2009. Participants included 1,254 pregnant and 2,326 postnatal women. The rate of antenatal depressive symptoms, i.e., a score of ≥10 on the Edinburgh Postnatal Depression Scale (EPDS) was 20.8%. Women attending clinics with primarily religious or traditional populations had lower rates antenatally than did those described as secular. During the postnatal period 16.3% of the women scored ≥10 on the EPDS. The rate of postnatal depressive symptoms was significantly higher among women living in Moslem than Druze communities (EPDS ≥ 10: 19.0% vs. 13.4%, respectively, P = 0.01). Postnatally, there were no significant differences according to SES cluster, community size, or religious orientation. The rate of antenatal and postnatal depression among Arab women in northern Israel was somewhat higher than that of Jewish Israeli women in the same region, and considerably lower than that of Arab Bedouin women in southern Israel. Given the differences in their life styles and circumstances, health policy authorities should be informed regarding the needs of these various sub-populations.
