Objective: The findings in retrospective pregnancy registries related to prenatal drug exposure (collected after pregnancy outcome is known) are commonly reported in regulatory documents and in the medical literature. However, there is little information about the accuracy of the estimates of risk from such registries. We therefore sought to compare the rates of major congenital malformations reported in retrospective and prospective registries for the same drug to quantify the potential bias of retrospective reports.

Introduction: H1 antihistamines are used for the treatment of nausea and vomiting during pregnancy as well as the symptomatic relief of asthma, urticaria, allergy, and the common cold. Although they are overall felt to be safe during pregnancy, recently several studies have challenged this assumption, as millions of women are exposed to them in the first trimester.

Methods: Following the guidelines of PRISMA, a systematic review was performed to retrieve all published articles involving H1-antihistamine exposure during pregnancy.

Purpose: The purpose of this study was to examine changes over time in the pooled effect size of randomized, double-blinded, placebo-controlled trials (RCTs) published on the protective effects of antioxidants and low dose aspirin against preeclampsia, and to identify determinants that may affect such changes.

Methods: Two recently published meta-analyses of RCTs examining the effects of antioxidant treatment or low dose aspirin on the rates of preeclampsia and its adverse effects were used. Chronological, cumulative meta-analyses were conducted to investigate the possibility of a time-dependent effect.

Second-generation antipsychotics (SGAs) are increasingly used for a variety of mental illnesses; however, the data regarding the safety of these medications during pregnancy are inconclusive and contradictory. We examined the risk of adverse pregnancy outcomes associated with in utero exposure to SGAs by conducting a systematic review and meta-analysis. We searched the databases EMBASE and MEDLINE from January 1990 to December 2014.

Purpose: There is a substantial body of research that utilizes saliva cortisol levels to examine wartime stress; however, there is a paucity of literature that utilizes hair cortisol levels, which allows for long-term assessment of chronic stress, to investigate the stress of war. The present study aimed to evaluate changes in hair cortisol concentrations before, during, and after the 2011 Libyan war.

Methods: This study examined hair cortisol concentrations of young adult women who were living in Tripoli, Libya during the 2011 war.

Pregnant women are almost always excluded from randomized controlled clinical trials, as the risks to the fetus posed by most new chemical entities or approved drugs cannot be sufficiently ruled out. Hence, a major scientific challenge in this field is to discover and validate alternative tools that will fill the knowledge gap created by the lack of participation in gold-standard randomized trials. This review focuses on novel tools that allow estimation of fetal risks after exposure to therapeutic agents, such as placental perfusion studies, biomarkers of fetal exposure, and novel epidemiological and pharmacogenetic tools, all of which have been tested successfully in recent years.

It typically takes many years before an association of a drug with a rare, serious adverse reaction is established. As related to pediatric drug use, evidence is even more erratic, as most drugs are used off labels. To enhance child safety, there is an urgent need to develop robust and rapid methods to identify such associations in as timely a manner as possible.

Background: Pemoline is a CNS stimulant that was introduced in 1975 in the US and was used to treat children with attention deficit hyperactivity disorder. Pemoline was withdrawn from the market 30 years later because of fatal hepatotoxicity associated with its use.

Objective: To create a system that will estimate the potential association between a serious adverse event and a medication early in its marketing cycle.
