BACKGROUND: Preconception health provides an opportunity to examine a woman's health status and address modifiable risk factors that can impact both a woman's and her child's health once pregnant. In this review, we aimed to investigate the preconception risk factors and interventions of early pregnancy and its impact on adverse maternal, perinatal and child health outcomes. METHODS: We conducted a scoping review following the PRISMA-ScR guidelines to include relevant literature identified from electronic databases...

Parental reflective functioning (PRF) refers to a parent's capacity to reflect on and understand the inner mental states of their child, their own mental states with regard to their child, and how these mental states may influence their behavior and interactions. This capacity has been shown to foster secure attachment in children and their socio-emotional development. The present study examined the psychometric properties of the Polish translation of the Parental Reflective Functioning Questionnaire (PRFQ), a brief screening measure of PRF, in a large community sample of Polish mothers of children aged 0-5 years (N = 979)...

IMPORTANCE: Autism spectrum disorder (ASD) is a neurodevelopmental disorder more prevalent in males than in females. The cause of ASD is largely genetic, but the association of genetics with the skewed sex ratio is not yet understood. To our knowledge, no large population-based study has provided estimates of heritability by sex. OBJECTIVE: To estimate the sex-specific heritability of ASD. DESIGN, SETTING, AND PARTICIPANTS: This was a population-based, retrospective analysis using national health registers of nontwin siblings and cousins from Sweden born between January 1, 1985, and December 31, 1998, with follow-up to 19 years of age...

INTRODUCTION: Neurological conditions such as Alzheimer's disease and stroke represent a substantial health burden to the world's ageing population. Cerebrovascular dysfunction is a key contributor to these conditions, affecting an individual's risk profile, age of onset, and severity of neurological disease. Recent data shows that early-life events, such as maternal health during pregnancy, birth weight and exposure to environmental toxins can 'prime' the vascular system for later changes...

Habitat loss is affecting many species, including the southern mountain caribou (Rangifer tarandus caribou) population in western North America. Over the last half century, this threatened caribou population's range and abundance have dramatically contracted. An integrated population model was used to analyze 51 years (1973-2023) of demographic data from 40 southern mountain caribou subpopulations to assess the effectiveness of population-based recovery actions at increasing population growth. Reducing potential limiting factors on threatened caribou populations offered a rare opportunity to identify the causes of decline and assess methods of recovery...

OBJECTIVES: To assess and quantify the association between pre-pregnancy maternal overweight and obesity, and the risk of congenital heart defects (CHDs) in offspring. METHODS: This systematic review and meta-analysis included searches of PubMed, Medline, Web of science, and Scopus up to April 20th, 2023. Risk estimates were abstracted or calculated for rising body mass index categories (overweight, obesity, moderate and severe obesity) compared to normal weight (reference)...

Objective: To explore associations between maternal characteristics and recall of obstetric provider actions in promoting antepartum tetanus-diphtheria-acellular-pertussis (Tdap) vaccination. Methods: A convenience sample of 1,682 postpartum women was surveyed in this cross-sectional study. Maternal characteristics and recall of four obstetric provider actions (recommending antepartum Tdap vaccine, offering it in clinic, providing written information, and referring patients elsewhere for vaccination) were collected...

BACKGROUND: Antibiotic exposure increases antimicrobial resistance and has also been associated with long-term harms, including allergies, inflammatory diseases and weight gain. We assessed antibiotic exposure in the first 2 years of life in Australian children, the factors influencing this and its appropriateness. METHODS: Data from 1201 participants in the MIS BAIR randomized controlled trial were used. Multivariable logistic regression was used to identify factors associated with antibiotic exposure...

BACKGROUND: Homemade peanut oil is widely consumed in rural areas of Southwestern China, which is easily contaminated by aflatoxins (AFs) and associated with adverse birth outcomes. OBJECTIVE: To identify the effect of exposure to homemade peanut oil consumption on low birth weight (LBW), preterm birth (PB) and other associated factors. METHODS: A prospective cohort study was conducted among pregnant women in Guangxi province, Southwestern China...

BACKGROUND: A single umbilical artery (SUA) may coexist with a single anomaly or multiple congenital anomalies. Although anomalies associated with SUA can primarily cause high perinatal mortality, their clinical significance has not been evaluated. OBJECTIVE: We investigated the relationship between the clinical features and the type or number of concurrent anomalies in neonates with SUA. MATERIALS AND METHODS: In this cross-sectional study, 104 neonates with SUA were enrolled from January 2000 to December 2020 at Dongsan hospital, Daegu, South Korea...

BACKGROUND: Early contraceptive implant removal without intentions to conceive predisposes women to unintended pregnancies.. Some of the unintended pregnancies end in unsafe abortions which further increases the risk of maternal mortality and morbidity. Therefore, we assessed the proportion of women who had early contraceptive implant removal. We also explored the reasons for early contraceptive implant removalamong women at Mbale Regional Referral Hospital in eastern Uganda. METHODS: We conducted a sequential explanatory mixed methods study at Mbale Regional Referral Hospital between November 2022 to December 2022...

BACKGROUND: Physiological processes rely on phosphate, which is an essential component of adenosine triphosphate (ATP). Hypophosphatasia can affect nearly every organ system in the body. It is crucial to monitor newborns with risk factors for hypophosphatemia and provide them with the proper supplements. We aimed to evaluate the risk factors and develop a nomogram for early hypophosphatemia in term infants. METHODS: We conducted a retrospective study involving 416 term infants measured serum phosphorus within three days of birth...

BACKGROUND: The Family Guidance Association of Ethiopia (FGAE) operates as a non-governmental organization dedicated to offering family planning and reproductive health services to the Ethiopian population. The gap in the study regarding client satisfaction and contributing factors towards sexual and reproductive health services for youth at FGAE clinics highlights the need for a comprehensive investigation to fill this void. By conducting a mixed-method study, this research aims to provide a holistic understanding of the factors influencing client satisfaction in the delivery of sexual and reproductive health services to youth at FGAE clinics...

INTRODUCTION: Capsular polysaccharide (CPS) serotype-specific Immunoglobulin G (IgG) in cord blood has been proposed as a correlate of protection against invasive Group B Streptococcus (iGBS) disease. Although protective levels are required in infants throughout the window of vulnerability up to 3 months of age, little is known regarding the kinetics of GBS-specific IgG over this period. METHODS: We enrolled 33 healthy infants born to mothers colonized with GBS...

BACKGROUND: Globally, there are about 800 maternal deaths every day, with low-to-middle-income countries accounting for most of these deaths. A lack of access to maternal healthcare services is one of the main causes of these deaths. In sub-Saharan Africa (SSA), one of the barriers to accessing maternal healthcare services by women is a lack of their male partners' involvement. This scoping review aimed to assess the enablers and barriers to men's involvement in maternal healthcare services...

BACKGROUND: Congenital heart defects are common and occur in approximately 0.9% of births. In France, the registries cover approximately 20% of the population but not the entirety of France; therefore, we aimed to update the incidence data for congenital heart defects in France from 2013 to 2022 using the medico-administrative database PMSI-MCO (French Medical Information System Program in Medicine, Surgery, and Obstetrics). We aimed to compare the frequency of risk factors in a population with congenital heart defects and a reference population...

BACKGROUND: Contraception is an important public health initiative for addressing maternal health outcomes associated with unplanned pregnancies, unsafe abortions and maternal deaths. Although contraceptive use has been on the rise globally, the observed increases in sub-Saharan Africa (SSA) are sub-optimal and vary among countries. In Zambia, drivers of contraceptive use transition are not well documented. Thus, this study examined the drivers of contraceptive use change among sexually active women in Zambia between 1992 and 2018...

CONTEXT: Due to the essential role of carnitine as an intermediary in amino acid, carbohydrate and lipid metabolism, a detailed characterization of circulating and urinary carnitine concentrations will aid in elucidating the molecular basis of impaired maternal metabolic flexibility and facilitating timely intervention for expectant mothers. OBJECTIVE: To investigate the association of maternal plasma and urinary free carnitine and acylcarnitines with cardiometabolic risk factors...

CONTEXT: Gestational diabetes mellitus (GDM) is a pregnancy complicated disease that poses a risk to maternal and infant health. However, the etiology of the disease has been not yet elucidated. OBJECTIVE: To detect the genetic susceptibility and construct a nomogram model with significantly associated polymorphisms and key clinical indicators for early prediction of gestational diabetes mellitus (GDM). METHODS: 11 functional single nucleotide polymorphisms (SNPs) screened by genome-wide association study (GWAS) were genotyped in 554 GDM cases and 641 healthy controls...

OBJECTIVE: This study aimed to evaluate the disparity of the expectations and basic knowledge of prenatal ultrasound (US) screening among pregnant women and make a comparison with the current scientific knowledge and national recommendations. We hypothesize that sociodemographic factors, including age, education, and professional occupation, may be associated with different levels of knowledge. METHODS: This was a cross-sectional study performed in 2021 of 336 women aged 18 to 46 years in a maternity facility in a tertiary hospital in Portugal...
