question:
To assess the relationship between congenital uterine malformations and blood pressure in pregnancy.', 'Twenty-four-hour automated ambulatory blood pressure monitoring (readings every 30 min) was performed in 16 normotensive, nonproteinuric, primigravidae with congenital uterine malformations (5 uterus septus, 9 uterus bicornis, 2 uterine didelphys) between 20 and 30 weeks. From the 24-hr blood pressure report, we calculated 24-hr mean, daytime and nighttime means. The results were compared with 16 primigravidae, matched for age and gestation, who were and remained normotensive throughout pregnancy, and tested for statistics with t-test; significance assessed at p < 0.001.', 'Although they were within the normotensive range, all blood pressure measurements considered were significantly higher in pregnant women with congenital uterine malformations, compared to normal pregnant women. Namely, 24-hr, daytime, and nighttime systolic (mean +/- SD) were 121.1 +/- 8.4, 124.4 +/- 8.8, 114.0 +/- 7.7 mmHg, respectively, in women with uterine malformations and 108.0 +/- 7.4, 109.2 +/- 7.3, 102.1 +/- 8.5 mmHg, respectively, in normal pregnant women. Twenty-four-hour diastolic, daytime, and nighttime diastolic (mean +/- SD) 74.1 +/- 10.2, 77.1 +/- 10.6, 68.1 +/- 9.2 mmHg, in women with uterine malformations and 64.1 +/- 5.7, 66.0 +/- 5.7, 58.2 +/- 6.3 mmHg, in normal pregnant women (all differences p < 0.001). Fifteen of the fetuses from women with congenital uterine malformations showed intrauterine growth retardation. No differences were found 6 months after delivery.
answer:
Are congenital uterine malformations associated to increased blood pressure in pregnancy?

question:
To determine the impact of the time interval from the end of sperm preparation (TSP) to intrauterine insemination (IUI) on the outcome.', 'Prospective multicentre cohort study.', 'Seven French centers (assisted reproduction group in northeastern France, four academic centers, and three clinics).', 'Eight hundred sixty-two IUI cycles (709 patients) managed by gonadotropins were studied.', 'Cycles were stimulated by either FSH or hMG, and hCG was administrated when the leading follicle diameter measured >15 mm. IUIs were performed 36 hours after ovulation triggering.', 'Generalized linear mixed models for binary outcomes were used to model clinical pregnancy (CP) to assess the effect of TSP adjusted for other predictors (such as maternal age, semen quality, and indication of IUI treatment).', 'The TSP effect was significant, featuring an inverse U-shaped curve admitting an optimum interval of 40-80 minutes improving CP compared with other values. Other significant predictors were total motile spermatozoa inseminated, maternal age, and unexplained infertility.
answer:
Is clinical success of intrauterine insemination cycles affected by the sperm preparation time?

question:
To determine whether a simple question about steadiness at admission predicts in-hospital functional decline and whether unsteadiness at admission predicts failure of in-hospital functional recovery of patients who have declined immediately before hospitalization.', 'Prospective cohort study.', 'One university hospital and one community teaching hospital.', 'One thousand five hundred fifty-seven hospitalized medical patients aged 70 and older.', 'On admission, patients reported their steadiness with walking and whether they could perform independently each of five basic activities of daily living (ADLs) at admission and 2 weeks before admission (baseline). For the primary analysis, the outcome was decline in ADL function between admission and discharge. For the secondary analysis, the outcome was in-hospital recovery to baseline ADL function in patients who experienced ADL decline in the 2 weeks before admission.', 'In the primary cohort (n = 1,557), 25% of patients were very unsteady at admission; 22% of very unsteady patients declined during hospitalization, compared with 17%, 18%, and 10% for slightly unsteady, slightly steady, and very steady patients, respectively (P for trend =.001). After adjusting for age; medical comorbidities; Acute Physiology, Age, and Chronic Health Evaluation II score; and admission ADL, unsteadiness remained significantly associated with ADL decline (odds for decline for very unsteady compared with very steady = 2.6, 95% confidence interval = 1.5-4.5). In the secondary analysis, predicting ADL recovery in patients who declined before hospitalization (n = 563), 46% of patients were very unsteady at admission. In this cohort, 44% of very unsteady patients failed to recover, compared with 35%, 36%, and 33% for each successively higher level of steadiness, respectively (P for trend = 0.06). After multivariate adjustment, greater unsteadiness independently predicted failure of recovery (P for trend = 0.02).
answer:
Does unsteadiness reported by older hospitalized patients predict functional decline?
