ObjectiveBlood type A and the A1 allele have been associated with increased ovarian cancer risk. With only two small studies published to date, evidence for an association between ABO blood type and ovarian cancer survival is limited.MethodsWe conducted a retrospective cohort study of Tumor Registry confirmed ovarian cancer cases from the Vanderbilt University Medical Center with blood type from linked laboratory reports and ABO variants from linked Illumina Exome BeadChip data. Associations with overall survival (OS) were quantified by hazard ratios (HR) and confidence intervals (CI) from proportional hazards regression models; covariates included age, race, stage, grade, histologic subtype, and year of diagnosis.ResultsABO phenotype (N = 694) and/or genotype (N = 154) data were available for 713 predominantly Caucasian (89.3%) cases. In multivariable models, blood type A had significantly better OS compared to either O (HR: 0.75, 95% CI: 0.60–0.93) or all non-A (HR: 0.77, 95% CI: 0.63–0.94) cases. Similarly, missense rs1053878 minor allele carriers (A2) had better OS (HR: 0.50, 95% CI: 0.25–0.99). Among Caucasians, this phenotype association was strengthened, but the genotype association was attenuated; instead, four variants sharing moderate linkage disequilibrium with the O variant were associated with better OS (HR: 0.62, 95% CI: 0.39–0.99) in unadjusted models.ConclusionsBlood type A was significantly associated with longer ovarian cancer survival in the largest such study to date. This finding was supported by genetic analysis, which implicated the A2 allele, although O related variants also had suggestive associations. Further research on ABO and ovarian cancer survival is warranted.

The oriental fruit moth (OFM), Grapholita molesta (Busck), is one of the dominant fruit-boring pests worldwide. In order to conduct integrated control of OFM effectively, it is important to predict the optimum control period. OFM populations have been monitored either by the number of trapped male moths exposed to sex pheromones or by the number of trapped male and female moths using food traps in orchards. The mating status and development stage of the trapped moths have not been characterized. The present paper studies the anatomical morphology of the OFM reproductive system at different development periods. The results revealed that OFM ovarian development can be divided into six stages. The average daily fecundity of OFM had an excellent positive correlation (r = 0.86) with the percentages of OFM in the egg maturation & oviposition stage, which could be used as an indicator in field population prediction work. There were obvious differences in the morphology of the corpus bursa and the heavy muscular area of the ductus ejaculatorius simplex before and after mating, and these differences could be used to increase the accuracy in predicting the optimum OFM control period.

Context The failure to collect information on lesbian, gay, bisexual, transgender, and queer (LGBTQ) identity in healthcare and medical education is a part of a systemic problem that limits academic medical institutions’ ability to address LGBTQ health disparities. Objectives To determine whether accurate sexual and gender minority (SGM) demographic data is being consistently collected for all US medical schools during admissions and enrollment, and whether differences exist between collection practices at osteopathic and allopathic schools. Methods Secure, confidential electronic were sent via email in July 2019 to 180 osteopathic (n=42) and allopathic (n=138) medical schools identified through the American Association of Colleges of Osteopathic Medicine Student Guide to Osteopathic Medical Colleges database and the American Association of Medical Colleges Medical School Admissions Requirements database. The nine question survey remained open through October 2019 and queried for; (1) the ability of students to self report SGM status during admissions and enrollment; and (2) availability of SGM specific resources and support services for students. Chi square analysis and the test for equality of proportions were performed. Results Seventy five of 180 (41.7%) programs responded to the survey; 74 provided at least partial data. Of the 75 respondent schools, 55 (73.3%) allowed applicants to self report a gender identity other than male or female, with 49 (87.5%) of those being allopathic schools compared with 6 (31.6%) osteopathic schools. Similarly, 15 (20.0%) allowed applicants to report sexual orientation, with 14 (25.5%) of those being allopathic schools compared with one (5.3%) osteopathic school. Fifty four of 74 (73.0%) programs allowed matriculants to self report a gender identity other than male or female; 11 of 74 (14.7%) allowed matriculants to report sexual orientation. Conclusions Demographics collection practices among American medical education programs that responded to our survey indicated that they undervalued sexual orientation and gender identity, with osteopathic programs being less likely than allopathic programs to report inclusive best practices in several areas. American medical education programs, and their supervising bodies, must update their practices with respect to the collection of sexual orientation and gender identity demographics as part of a holistic effort to address SGM health disparities.
