#1
Carolina Vaz-de-Macedo, Joyce Harper
Conventionally, the search for carrier status was based on ethnicity and/or family history and targeted to a restricted number of genetic conditions and mutations. This is now being replaced by extended panels testing for hundreds of genetic disorders with a broad range of phenotypes, in what is called 'expanded carrier screening'. While the ultimate aim of these panels is to increase the reproductive autonomy of the individuals and couples by providing preconception knowledge that could lead to the broadest range of available options, including PGD, we argue that: (i) Given the number and heterogeneity of the conditions included in panels, it cannot be guaranteed that a couple who tests positive for one of those conditions will be eligible for PGD; patients should be informed of this potential limitation before undertaking screening...

Context: Women with polycystic ovary syndrome (PCOS) commonly have intrinsic insulin resistance and are recommended to undergo an oral glucose tolerance test (OGTT) for diabetes screening. However, the effect of preconception impaired glucose tolerance (IGT) on pregnancy is still unclear. Objective: To prospectively assess the effect of preconception IGT on pregnancy outcomes. Design, Setting, Patients, Intervention(s) and Main Outcome Measure(s): This was a secondary analysis of a multicenter randomized trial in 1508 women with PCOS comparing live birth and obstetric complications between fresh and frozen embryo transfer...

Cannabis sativa (marijuana) is the illicit drug most commonly used during pregnancy. The self-reported prevalence of marijuana use during pregnancy ranges from 2% to 5% in most studies. A growing number of states are legalizing marijuana for medicinal or recreational purposes, and its use by pregnant women could increase even further as a result. Because of concerns regarding impaired neurodevelopment, as well as maternal and fetal exposure to the adverse effects of smoking, women who are pregnant or contemplating pregnancy should be encouraged to discontinue marijuana use...

BACKGROUND: Neural tube defects are among the most common birth defects, contributing to miscarriage, infant mortality, severe congenital abnormalities and serious disabilities. It is burdensome to patients, caregivers, healthcare systems and society. It could be reduced if women consume a folic acid supplement before and during the early weeks of pregnancy. This study assesses folic acid usage and associated factors for the prevention of neural tube defects among pregnant women in Ethiopia...

24-year-old woman at 28 weeks gestation was referred from peripheral hospital with diagnosis of pregnancy with portal hypertension. She had received multiple transfusion for pancytopaenia in the past and had undergone endoscopic sclerotherapy for oesophageal varices. Initially, she was admitted in our hospital at 28 weeks gestation for blood transfusion and was evaluated by multispecialty team of doctors. She was advised splenectomy for transfusion-dependent pancytopaenia secondary to hypersplenism in non-cirrhotic portal hypertension...

BACKGROUND: There is a well-documented decline in fertility treatment success with increasing female age; however, there are few preconception cohort studies examining female age and natural fertility. In addition, data on male age and fertility is inconsistent. Given the increasing number of couples attempting conception at older ages, a more detailed characterization of age-related fecundability in the general population is of great clinical utility. OBJECTIVE: To examine the association between female and male age with fecundability...

Bidirectional transplacental exchange characterizes human pregnancy. Cells exchanged between mother and fetus can durably persist as microchimerism and may have both short- and long-term consequences for the recipient. The amount, type, and persistence of microchimerism are influenced by obstetric characteristics, pregnancy complications, exposures to infection, and other factors. A reproductive-aged woman enters pregnancy harboring previously acquired microchimeric "grafts," which may influence her preconception health and her subsequent pregnancy outcomes...

There is a growing realisation that efforts to optimise the health of women and reduce the risk of adverse maternal, perinatal and neonatal outcomes during pregnancy should commence in the preconception period. The preconception period (prior to or between pregnancies) provides an opportune time to address reproductive intentions and promote and support wellbeing and healthy behaviour change regardless of pregnancy intention. Research over the last 30 years has explored the influence of a range of preconception risk factors and determinants of health on pregnancy and maternal and neonatal outcomes including: pregnancy planning, diet and micronutrient supplementation, physical activity, weight, smoking, recreational drug and alcohol use, mental health, oral hygiene, and chronic health and medical conditions...

REVIEW
Aleksandra Sherman, Clair Morrissey
Scientists, humanists, and art lovers alike value art not just for its beauty, but also for its social and epistemic importance; that is, for its communicative nature, its capacity to increase one's self-knowledge and encourage personal growth, and its ability to challenge our schemas and preconceptions. However, empirical research tends to discount the importance of such social and epistemic outcomes of art engagement, instead focusing on individuals' preferences, judgments of beauty, pleasure, or other emotional appraisals as the primary outcomes of art appreciation...

Despite the lifecourse focus of nursing clinical care, nursing research largely remains cross-sectional or process-oriented within silos determined by patient characteristics such as age, acuity, or disease process. Incorporating interdisciplinary lifecourse theory into pediatric nursing research provides the opportunity to expand nursing theories and research beyond practice, age, and disease silos. One such theory is the Lifecourse Health Development (LCHD) framework. LCHD takes a more expansive view of health development from preconception through old age based on the premise that health is a consequence of transactions between genetic, biological, behavioral, social, and economic contexts that change as a child develops over time (Halfon & Hochstein, 2002)...

OBJECTIVE Infant hydrocephalus is estimated to affect more than 100,000 new infants each year in sub-Saharan Africa (SSA). Bugando Medical Centre (BMC), a government-funded and patient cost-shared referral center, serves over 13 million people in the Lake and Western regions of Tanzania. The goals of this study were to characterize the infant population affected by hydrocephalus who presented to BMC and were treated with a ventriculoperitoneal shunt (VPS) to determine the rate of early complications associated with this surgical procedure and to assess its potential risk factors...

BACKGROUND: Excess gestational weight gain (GWG) leads to adverse short- and long-term consequences for women and their offspring. Evidence suggests that excess GWG in early pregnancy may be particularly detrimental, contributing to the intergenerational cycle of obesity. The primary outcome was to investigate the prevalence and predictors of excess GWG in early pregnancy, and if women understand the risks to themselves and their offspring stratified by maternal body mass index (BMI)...

BACKGROUND: The human papillomavirus (HPV) vaccine was developed to prevent infection with strains of HPV that cause cervical cancer. While HPV infection has been associated with reduced semen quality and lower pregnancy rates in some studies, no studies have examined the relationship between HPV vaccination and fecundability. We hypothesize that HPV prevention via vaccination will protect fecundity. METHODS: We analysed data from Pregnancy Study Online (PRESTO), a preconception cohort of North American pregnancy planners...

BACKGROUND: Prenatal alcohol exposure can affect neurodevelopment, but few studies have examined associations with autism spectrum disorder (ASD). METHODS: We assessed the association between maternal alcohol use and ASD in the Study to Explore Early Development, a multi-site case-control study of children born between September 2003 and August 2006 in the US Regression analyses included 684 children with research clinician-confirmed ASD, 869 children with non-ASD developmental delays or disorders (DDs), and 962 controls ascertained from the general population (POP)...

Previous paleoparasitological studies of Joseon specimens established that the prevalence of Taenia infection was not much different from that of the early 20th century Korean population. As many of taeniases originally diagnosed as Taenia saginata in South Korea were revealed to be actually Taenia asiatica, which share a common intermediate host with T. solium (the pig), Joseon people must have ingested raw pork frequently. However, the current examination of extant Joseon documents revealed that the population ate significant amounts of beef even if the beef ban was enforced; and pork was not consumed as much as we thought...

Background: Quantifying syphilis prevalence is important for planning interventions and advocating for resources on syphilis. However, data on large sample studies regarding the prevalence of syphilis among reproductive-age women in rural China were not available for analysis. The aim of the study was to determine the prevalence, epidemiological characteristics, and related factors of syphilis infection among reproductive-age women in rural China. Methods: Data were obtained from a nationwide, population-based, cross-sectional study under the National Free Preconception Health Examination Project which covered all the 31 provinces in Mainland China...

BACKGROUND: Preconception care, including family planning, is a vital component of healthcare for women of reproductive age. An average female spends the majority of her reproductive life trying to prevent a pregnancy. In order to prevent unintended pregnancy, women often rely on the use of hormonal contraceptives. In the United States, the majority of hormonal contraceptive users are prescribed oral contraceptive pills (OCPs). Reduced adherence to OCPs decreases their ability to prevent pregnancy...

Decision-making related to pregnancy planning is complex and human immunodeficiency virus (HIV) may further complicate the process. With increasing rates of pregnancy among individuals affected by HIV, the need to understand decision-making is imperative. The primary objectives of this pilot study were to confirm the feasibility of using discrete choice experimentation (DCE) to elicit an understanding of this process and to determine the acceptability of the choice factors that were included in two novel DCEs, while gathering a preliminary understanding of preference...
