Nausea and Vomiting of Pregnancy and its Management with the Dual-Release Formulation of Doxylamine and Pyridoxine.

Nausea and vomiting of pregnancy (NVP) is among the most common conditions that pregnant women encounter in the early stages of pregnancy. It can affect up to 85% of pregnant women, thus representing a significant public health concern. NVP results in substantial negative physical, emotional, and financial consequences. Despite its prevalence, the pathogenesis remains elusive. Few guidelines have been published; however, several interventions exist for the symptomatic treatment of NVP. The aim of this review is to provide an overview of modern treatment strategies of NVP with a special focus on the recently approved dual-release formulation of the doxylamine and pyridoxine combination. This combination was approved by the Food and Drug Administration (FDA) in November 2016 for the treatment of NVP when conservative management fails, and it has been introduced to the American market in April 2018. The maximum plasma concentration (T max ) of doxylamine and pyridoxal-5-phosphate is reached 3.5 h and 15 h, respectively, after administration of one tablet twice daily, or 4.5 h and 0.5 h, respectively, when one tablet is administered just once daily. In addition, the delayed-release combination allows sufficient levels of doxylamine and the active metabolite pyridoxal-5-phosphate in the systemic circulation, providing symptoms relief in the subsequent morning. Hence, the dual-release formulation can improve the quality of life of pregnant women suffering from NVP. Additionally, large epidemiological trials have shown no increased risk of adverse effects to newborns, demonstrating that its use is not teratogenic.

Ocular changes during pregnancy.

BACKGROUND: Most ocular changes in pregnancy are harmless. For example, 14% of pregnant women need a new eyeglass prescription. Some changes, however, are serious, such as retinal effects of hypertension, which can be a sign of pre-eclampsia. Ocular changes may give rise to uncertainty about the administration of ophthalmological drugs or the optimal method of childbirth. METHOD: This review is based on pertinent literature retrieved by a selective search in Medline and on guidelines from Germany and abroad. Recommendations about drugs were taken from the Embryotox and Reprotox databases, the German Red List, and the United States Food and Drug Administration (FDA). RESULTS: 40% to 100% of pregnant women with high blood pressure have retinal changes whose severity is correlated with the severity of pre-eclampsia or eclampsia. Diabetic women should undergo ocular examination before and during pregnancy. Pre-existing retinal changes worsen during pregnancy in 55% of cases. Most ocular diseases can be treated with the usual drugs in pregnant women and nursing mothers, although the evidence for drug safety is derived from case series and the treatment is usually provided off label. Ocular conditions that are present before pregnancy are irrelevant to the choice of a method of childbirth. CONCLUSION: Pregnant women and nursing mothers can undergo most types of ophthalmological examination and treatment. Recommendations about drug treatment should be checked against current information that can be found on the embryotox.de and reprotox.de websites.

Influence of acupuncture on the pregnancy rate in patients who undergo assisted reproduction therapy.

OBJECTIVE: To evaluate the effect of acupuncture on the pregnancy rate in assisted reproduction therapy (ART) by comparing a group of patients receiving acupuncture treatment shortly before and after embryo transfer with a control group receiving no acupuncture. DESIGN: Prospective randomized study. SETTING: Fertility center. PATIENT(S): After giving informed consent, 160 patients who were undergoing ART and who had good quality embryos were divided into the following two groups through random selection: embryo transfer with acupuncture (n = 80) and embryo transfer without acupuncture (n = 80). INTERVENTION(S): Acupuncture was performed in 80 patients 25 minutes before and after embryo transfer. In the control group, embryos were transferred without any supportive therapy. MAIN OUTCOME MEASURE(S): Clinical pregnancy was defined as the presence of a fetal sac during an ultrasound examination 6 weeks after embryo transfer. RESULT(S): Clinical pregnancies were documented in 34 of 80 patients (42.5%) in the acupuncture group, whereas pregnancy rate was only 26.3% (21 out of 80 patients) in the control group. CONCLUSION(S): Acupuncture seems to be a useful tool for improving pregnancy rate after ART.
