Oxygen therapy provides an important treatment for preterm and low-birth-weight neonates, however, it has been shown that prolonged exposure to high levels of oxygen (hyperoxia) is one of the factors contributing to the development of bronchopulmonary dysplasia (BPD) by inducing lung injury and airway hyperreactivity. There is no effective therapy against the adverse effects of hyperoxia. Therefore, this study was undertaken to test the hypothesis that natural phytoalexin resveratrol will overcome hyperoxia-induced airway hyperreactivity, oxidative stress, and lung inflammation...

In July 2020, Hong Kong extended statutory paid maternity leave from ten weeks to fourteen weeks to align with International Labour Organization standards. We used the policy enactment as an observational natural experiment to assess the mental health implications of this policy change on probable postnatal depression (Edinburgh Postnatal Depression Scores of 10 or higher) and postpartum emotional well-being. Using an opportunistic observational study design, we recruited 1,414 survey respondents with births before (August 1-December 10, 2020) and after (December 11, 2020-July 18, 2022) policy implementation...

Women who are pregnant or recently gave birth are significantly more likely to be killed by an intimate partner than nonpregnant, nonpostpartum women of reproductive age, implicating the risk of fatal violence conferred by pregnancy itself. The rapidly increasing passage of state legislation has restricted or banned access to abortion care across the US. We used the most recent and only source of population-based data to examine the association between state laws that restrict access to abortion and trends in intimate partner violence-related homicide among women and girls ages 10-44 during the period 2014-20...

Antiretrovirals are often approved by the Food and Drug Administration without sufficient safety data regarding their use in pregnancy. To quantify this delay, we calculated the interval from the approval date to their inclusion in the Antiretroviral Pregnancy Registry prospective analysis (≥ 200 first trimester exposures); median delay was six years.

The early gut microbiota composition is fundamentally important for piglet health, affecting long-term microbiome development and immunity. In this study, the gut microbiota of postparturient dams was compared with that of their offspring in three Finnish pig farms at three growth phases. The differences in fecal microbiota of three study development groups (Good, Poorly, and PrematureDeath) were analyzed at birth (initial exposure phase), weaning (transitional phase), and before slaughter (stable phase). Dam Lactobacillaceae abundance was lower than in piglets at birth...

Men who have sex with men (MSM) and transgender women (TW) are disproportionally affected by HIV infection. This cross-sectional study evaluated the HIV-1/2 prevalence, risk factors and HIV molecular features of MSM and TW from Midwest Brazil. Four hundred and thirty participants (278 MSM and 152 TW) from Mato Grosso do Sul, Brazil, were interviewed and tested for HIV-1/2 infection between November 2011 and September 2013. Participants who were assigned male at birth, older than 18 years old and self-declared as MSM or TW were recruited from LGBT+ associations, as well as public (parks, square, streets, etc) and private [nightclubs, saunas, brothels, etc] places...

OBJECTIVE: To assess the effectiveness of early neurodevelopmental assessments in identifying cerebral palsy and cognitive and other neurodevelopmental impairments, including their severity, within a multidisciplinary clinic. DESIGN, SETTING, AND PARTICIPANTS: This diagnostic study was conducted at Monash Children's Hospital, Melbourne, Australia...

IMPORTANCE: Although whole-body hypothermia is widely used after mild neonatal hypoxic-ischemic encephalopathy (HIE), safety and efficacy have not been evaluated in randomized clinical trials (RCTs), to our knowledge. OBJECTIVE: To examine the effect of 48 and 72 hours of whole-body hypothermia after mild HIE on cerebral magnetic resonance (MR) biomarkers. DESIGN, SETTING, AND PARTICIPANTS: This open-label, 3-arm RCT was conducted between October 31, 2019, and April 28, 2023, with masked outcome analysis...

IMPORTANCE: The incidence of gastroschisis, a birth defect involving the herniation of the small bowel through the abdominal wall, has increased in the US since the 1960s. The pesticide atrazine is a hypothesized cause of gastroschisis; however, examination of the association between atrazine and gastroschisis has been limited. OBJECTIVE: To evaluate national trends in gastroschisis incidence, maternal and infant characteristics associated with gastroschisis, and whether county-level atrazine use is associated with gastroschisis...

BACKGROUND: Preterm birth and low birthweight (LBW) might be associated with reduced physical fitness, although evidence remains inconclusive. OBJECTIVE: To examine the influence of preterm birth and LBW on physical fitness, as well as to assess whether variables such as gestational age, birthweight, or age at assessment moderate these effects. METHODS: PubMed, Scopus, and PsycINFO were systematically searched from inception to 7 December 2023 for case-control and cohort studies analyzing the association between preterm birth or LBW (or gestational age or birthweight as continuous variables) with at least one physical fitness-related outcome (i...

BACKGROUND: Fertilization failure often occurs in conventional IVF cycles, and day 1 rescue ICSI is frequently recommended. In this study, the effect of rescue ICSI on obstetrical and neonatal outcomes after a single blastocyst transfer in vitrified-warmed cycles is evaluated. METHODS: This cohort study was a retrospective analysis of 703 vitrified-warmed single blastocyst transfers and 219 singletons in the r-ICSI group compared with 11,611 vitrified-warmed single blastocyst transfers in the IVF/ICSI and 4472 singletons in the IVF/ICSI group, respectively, and patients just undergoing their first IVF treatments were included in this study...

Considerable integrative efforts have been made to investigate the effects of fluoride on female reproductive organs since the last years. The ingestion of fluoride causes adverse effects on human health like causing skeletal fluorosis, dental fluorosis, bone fractures, kidney problems, decrease birth rates, weakening of thyroid functionality, and impair intelligence, particularly in children. In this review, we discuss the adverse effects of fluoride on female reproductive organs and presented certain remedies...

In neoliberal cultural contexts, where the ideal prevails that female bodies should be unchanged by reproductive processes, women often feel uncomfortable with their postpartum bodies. Cesareaned women suffer from additional discomfort during the postpartum period, and cesarean births are associated with less satisfying childbirth experiences, fostering feelings of failure among women who had planned a vaginal delivery. In Switzerland, one in three deliveries is a cesarean. Despite the frequency of this surgery, women complain that their biomedical follow-up provides minimal postpartum support...

OBJECTIVES: To examine the experiences of pregnant Hispanic/Latine people with COVID-19, as well as their perspectives on COVID-19 vaccination in pregnancy. METHODS: We interviewed birthing parents who received care from a teaching hospital in California and tested positive for COVID-19 during pregnancy or delivery. We analyzed transcripts using the constant comparative method for analyzing data to using a phenomological epidemiological approach. We used root cause analysis to identify consistent themes across interviews and assess relationships between social determinants of health and COVID-19 infectivity...

BACKGROUND: Atopic dermatitis (AD) affects individuals of all ages, and the first-line treatment are emollients and topical corticosteroids. There is insufficient knowledge about factors possibly affecting the drug utilization of young adults with AD. OBJECTIVES: To describe the drug utilization of young adults with AD in relation to sex, socio-economic status and disease severity. METHODS: A cross-sectional study based on the 24-year follow-up from the population-based BAMSE (Children, Allergy, Milieu, Stockholm, Epidemiology Survey) birth cohort linked with dispensing data from the National Drug Register (n = 2912)...

Single-cell sequencing technologies enhance our understanding of cellular dynamics throughout pregnancy. We outlined the workflow of single-cell sequencing techniques and reviewed single-cell studies in maternal and child health. We conducted a literature review of single cell studies on maternal and child health using PubMed. We summarized the findings from 16 single-cell atlases of the human and mammalian placenta across gestational stages and 31 single-cell studies on maternal exposures and complications including infection, obesity, diet, gestational diabetes, pre-eclampsia, environmental exposure and preterm birth...

IMPORTANCE: Hypertension affects 6% of all children, and its prevalence is increasing. Childhood hypertension tracks into adulthood and is associated with subclinical cardiovascular disease; however, there is a lack of evidence linking childhood hypertension to cardiovascular outcomes, which may contribute to underdiagnosis and undertreatment. OBJECTIVE: To determine the long-term associated risk of major adverse cardiac events (MACE) among children diagnosed with hypertension...

Long-acting cabotegravir is approved for pre-exposure prophylaxis and combination HIV treatment, both initiated with optional short-term oral lead-in (OLI). We evaluated the impact of OLI on long-acting cabotegravir pharmacokinetics. Cabotegravir plasma concentrations were compared between HIV-positive participants initiating injections with ( n = 278) or without ( n = 110) OLI in phase III treatment study FLAIR and in HIV-negative participants using OLI ( n = 263) in pivotal pre-exposure prophylaxis studies HPTN 083 and HPTN 084...

INTRODUCTION: Second-degree perineal tears following vaginal birth are common and presumed to be of little clinical importance. However, the extent of damage to the perineal body varies widely, and there is reason to believe that larger second-degree tears may be associated with more pelvic floor symptoms, compared to lesser form. Therefore, the aim of this study was to assess differences in pelvic floor symptoms according to the severity of second-degree perineal tears up to 12 months post-partum, stratified by parity...
