Nausea and vomiting of pregnancy (NVP) is a common medical condition in pregnancy with significant physical and psychological morbidity. Up to 90% of women will suffer from NVP symptoms in the first trimester of pregnancy with up to 2% developing hyperemesis gravidarum which is NVP at its worst, leading to hospitalization and even death in extreme cases. Optimal management of NVP begins with nonpharmacological approaches, use of ginger, acupressure, vitamin B6, and dietary adjustments. The positive impact of these noninvasive, inexpensive and safe methods has been demonstrated. Pharmacological treatments are available with varying effectiveness; however, the only drug marketed specifically for the treatment of NVP in pregnancy is Diclectin® (vitamin B6 and doxylamine). In addition, the Motherisk algorithm provides a guideline for use of safe and effective drugs for the treatment of NVP. Optimal medical management of symptoms will ensure the mental and physical wellbeing of expecting mothers and their developing babies during this often stressful and difficult time period. Dismissing NVP as an inconsequential part of pregnancy can have serious ramifications for both mother and baby.
Exposure to natalizumab in early pregnancy does not appear to increase the risk of adverse pregnancy outcomes in comparison to a DM group not exposed to natalizumab.
Background: This study quantified and compared weekday and weekend patterns of device-measured physical activity (PA) and sedentary behavior between youth with pediatric multiple sclerosis (MS) and controls for the purpose of informing future PA behavior change interventions.
Methods: Participant data were obtained from three ongoing observational studies, and the sample included 40 participants with pediatric MS and 41 controls. Light PA (LPA), moderate-to-vigorous PA (MVPA), and sedentary behavior data were collected using activity monitors (ActiGraph LLC) over 1 week. The main analysis involved a two-way mixed factor analysis of variance with group as a between-subjects factor (pediatric MS vs control) and day as a within-subjects factor (weekday vs weekend day).
Results: There was no group × day interaction from the analysis of variance for percentage of activity monitor wear time spent in LPA, MVPA, or sedentary behavior. There was no effect of group for LPA, MVPA, or sedentary behavior. There was an effect of day of week on percentage of day spent in LPA, MVPA, and sedentary behavior.
Conclusions: These results suggest that youth with pediatric MS and controls were less physically active and more sedentary on weekends than on weekdays, but there were no differences between groups in PA and sedentary behavior overall or by day of the week. Physical activity interventions may be more successful by initially targeting weekend day activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
