Review Meta AnalysisExercise during pregnancy and risk of preterm birth in overweight and obese women: a systematic review and meta-analysis of randomized controlled trials.
The incidence of overweight and obesity in pregnancy has risen significantly in the last decades. Overweight and obesity have been shown to increase the risk for some adverse obstetric outcomes. Lifestyle interventions, such as diet, physical activity and behavior changes, may reduce these risks by promoting weight loss and/or preventing excessive weight gain. The possible impact of exercise on the risk of preterm birth (PTB) in overweight or obese women is controversial. Therefore, the aim of our study was to evaluate the effect of exercise on the risk of PTB in overweight or obese pregnant women. ⋯ Overweight and obese women with singleton pregnancy can be counseled that, compared with being more sedentary, aerobic exercise for about 30-60 min three to seven times per week during pregnancy is associated with a reduction in the incidence of PTB. Aerobic exercise in overweight and obese pregnant women is also associated with a significant prevention of gestational diabetes mellitus, and should therefore be encouraged.

Why babies die in unplanned out-of-institution births: an enquiry into perinatal deaths in Norway 1999-2013.
The aims were to describe causes of death associated with unplanned out-of-institution births, and to study whether they could be prevented. ⋯ Infections, neonatal, and placental causes accounted for almost two-thirds of perinatal mortality associated with unplanned out-of-institution births in Norway. Sub-optimal maternal use of available care was found in more than one-fifth of cases.

Risk factors for recurrence of hypertensive disorders of pregnancy, a population-based cohort study.
Hypertensive disorders of pregnancy (HDP) tend to recur from one pregnancy to the next. The aims of the study were to assess the recurrence risk according to type of HDP defined by gestational age at birth and to examine whether recurrence is associated with the following additional risk factors for HDP: maternal age, smoking, inter-delivery interval, diabetes, body mass index, and fetal growth restriction, and to assess temporal trends in these associations. ⋯ Recurrent HDP tended to be of the same type as the previous HDP. Risk of recurrence associated with additional risk factors was observed particularly after term. The odds ratio of recurrence of early preterm HDP was significantly lower from 1993 onwards.

Human papillomavirus test with cytology triage in organized screening for cervical cancer.
In randomized studies, testing for high-risk (HR) human papillomavirus (hrHPV) has been more sensitive than conventional cytology in detecting cervical intraepithelial neoplasia (CIN). The aim of this study was to evaluate the performance of HPV testing in the setting of an organized routine screening program. ⋯ Human papillomavirus testing also seems to be more sensitive than cytology in detecting CIN2+ lesions in the setting of a routine organized screening program, besides in the context of randomized trials. The problem of an increased colposcopy rate needs to be addressed in the future.
