Survival of patients with BRCA1-associated breast cancer diagnosed in an MRI-based surveillance program.

Abstract: We report the 5- and 10-year survival rate of women diagnosed with breast cancer in the context of an annual MRI-based surveillance program. In 2001, as part of a national initiative, women in Norway with a BRCA1 mutation were offered annual screening with breast MRI in addition to mammography. 802 women with a BRCA1 mutation were screened one or more times and followed for a mean of 4.2 years. As of December 2011, 68 of 802 women in the screening program were diagnosed with DCIS or invasive breast cancer (8.5 %), including eight prevalent, 50 incident screen-detected and eight interval cancers. Two latent cancers were detected at prophylactic mastectomy. Sixty-three of the cancers were invasive and five were in situ. The mean tumour size was 1.4 cm (range 0.2–4.5 cm), and 85 % of the patients were node-negative. Ten of the 68 patients died of cancer in the follow-up period. The 5-year breast cancer-specific survival for women with cancer was 75 % (95 % CI 56–86 %) and the 10-year survival was 69 % (95 % CI: 48–83 %). The 5-year survival for women with Stage 1 breast cancer was 82 % compared to 98 % in the population. The 5- and 10-year survival of women with a BRCA1-associated breast cancer detected in a national MRI-based screening program in BRCA1 mutation carriers Norway was less than anticipated. The benefit of annual MRI surveillance on reducing breast cancer mortality in BRCA1 mutation carriers remains to be proven.

The Association Between Antenatal Exposure to Selective Serotonin Reuptake Inhibitors and Autism: A Systematic Review and Meta-Analysis.

Abstract: OBJECTIVE This systematic review and meta-analysis examines the relationship between antenatal selective serotonin reuptake inhibitor (SSRI) exposure and child autism, with specific attention to maternal mental illness (MMI) as a potential confounding factor. DATA SOURCES We searched MEDLINE, Embase, PsycINFO, and CINAHL from database inception to January 28, 2016. STUDY SELECTION Keywords included terms for SSRIs, pregnancy, and autism. We included published, peer-reviewed articles written in English. DATA EXTRACTION Two reviewers used standardized instruments for data extraction and quality assessment. We generated pooled estimates for studies of the same design for SSRI exposure at any time during pregnancy and exposure during the first trimester. Subanalyses were conducted among studies with analyses (1) adjusted for MMI and (2) restricted to MMI. RESULTS We included in the meta-analysis 4 case-control studies and 2 cohort studies. In the case-control studies, the adjusted pooled odds ratio (aPOR) values were 1.4 (95% CI, 1.0-2.0) (any) and 1.7 (95% CI, 1.1-2.6) (first trimester). In MMI-adjusted analyses, only first trimester exposure remained statistically significant (aPOR = 1.8; 95% CI, 1.1-3.1). In MMI-restricted analyses, neither exposure period was statistically significant. In the cohort studies, MMI-adjusted relative risk values were 1.5 (95% CI, 0.9-2.7) (any) and 1.4 (95% CI, 1.0-1.9) (first trimester). In MMI-restricted analyses, SSRI exposure at any time during pregnancy was nonsignificant. CONCLUSIONS It remains unclear whether the association between first trimester SSRI exposure and child autism that was present in the case-control studies even after adjustment for MMI is a true association or a product of residual confounding. Future studies require robust measurement of MMI prior to and during pregnancy.

Physical arrangement of retrotransposon-related repeats in centromeric regions of wheat.

Abstract: Cereal centromeres commonly contain many repetitive sequences that are derived from Ty3/gypsy retrotransposon. FISH analysis using a large DNA insert library of wheat identified a 67-kb clone (R11H) that showed strong hybridization signals on the centromeres. The R11H clone contains Ty3/gypsy retrotransposon-related sequences; both integrase and CCS1 family sequences were identified. Subsequently, we isolated additional 23 large-insert clones which also contained the integrase and CCS1 sequences. Based on the number of the integrase repeats in the clones determined by DNA gel blot analysis, we concluded that the retrotransposon-like sequences are tandemly repeated in wheat centromeres in ca. 55-kb interval on average. This conclusion is consistent with the results of FISH analysis on the extended DNA fibers.
