question:
To determine the role of factor V Leiden and prothrombin gene mutation in the pathogenesis of unexplained second and third trimester nonrecurrent fetal loss.', 'One hundred and fourteen women with unexplained nonrecurrent late fetal loss made up the study group, and 106 normal pregnant women with a history of delivery of at least one healthy fetus and no history of late fetal loss made up the control group. The study group was further divided into two subgroups: second (n = 36) and third (n = 78) trimester fetal loss. All women were tested for factor V Leiden and G20210A prothrombin gene mutations.', 'Twenty-one (18.4%) of the women in the study group and seven (6.6%) of the women in the control group were heterozygous carriers of factor V Leiden mutation (OR = 3.19). Eleven (9.6%) of the women in the study group and three (2.8%) of the women in the control group were heterozygous carriers of prothrombin gene mutation (OR = 3.66). In assessing with regard to trimesters, 18 (23%) factor V Leiden and 10 (12.8%) prothrombin gene mutations were present in the group of third trimester fetal loss (OR = 4.24 and OR = 5.04, respectively). Three (8.3%) factor V Leiden and one (2.7%) prothrombin gene mutation were detected in women with second trimester fetal loss (OR = 1.28 and OR = 0.40, respectively).
answer:
Is third trimester nonrecurrent fetal loss associated with factor V Leiden and prothrombin gene mutations?


question:
The objective of this study was to compare health-related quality of life (HR-QoL), disability/work productivity, and health care utilization in a variety of medical disorders with and without comorbid major depressive disorder (MDD) in the general population.', 'Twelve-month MDD (Composite International Diagnostic Interview) diagnosis was determined among 4181 participants from a community sample. Medical diagnoses (respiratory, cardiovascular, allergic, endocrine/metabolic, gastrointestinal, and neurological diseases) were made after medical examination. HR-QoL was evaluated with the MOS-SF-36. Outpatient doctor visits and disability/work productivity were assessed by self-report.', 'Comorbid MDD was associated with a lower SF-36 mental summary score in all medical diagnoses and with a lower physical summary score in comorbid allergic and neurological disorders. The number of coexisting medical disorders was strongly related to lower physical and mental summary scores in cases without comorbid depression. The number of outpatient doctor visits increased by 42% when any of the medical disorders without comorbid MDD was present, and comorbid MDD was associated with a further 24-42% increase, depending on the medical disorder. Comorbid MDD was strongly associated with lower full-time working status (37.1% with MDD vs. 51.0% without MDD) and with a significant increase in disability days (45%) in the presence of any medical disorder.
answer:
Do medical disorders affect health outcome and general functioning depending on comorbid major depression in the general population?


question:
Violence-exposed youth rarely receive mental health services, even though exposure increases risk for academic and psychosocial problems. This study examines the association between violence exposure and mental health service contact. The 4 forms of violence exposure were peer, family, sexual, and witnessing.', 'Data are from 1534 Boston public high school students who participated in a 2008 self-report survey of violence exposure and its correlates. Multivariate logistic regressions estimated associations between each form of violence with service contact, then examined whether associations persisted when controlling for suicidality and self-injurious behaviors.', 'In unadjusted models, violence-exposed students more often reported service contact than their peers. However, in multivariate models, only exposure to family (odds ratio [OR] = 1.69, 95% confidence interval [CI] = 1.23-2.31) and sexual violence (OR = 2.34, 95% CI = 1.29-4.20) were associated with service contact. Associations attenuated when controlling for suicidality and self-injurious behaviors, indicating they were largely explained by self-harm. Sexual violence alone remained associated with mental health service contact in fully adjusted models, but only for girls (OR=3.32, 95% CI=1.30-8.45), suggesting sex-specific pathways.
answer:

Do mental health service use among high school students exposed to interpersonal violence?
