Prevalence of low birth weight and macrosomia estimates based on heaping adjustment method in China.

Low birth weight (< 2500 g; LBW) and macrosomia (> 4000 g) are both adverse birth outcomes with high health risk in short- or long-term period. However, national prevalence estimates of LBW and macrosomia varied partially due to methodology limits in China. The aim of this study is to estimate the prevalence of LBW and macrosomia after taking potential birth weight heaping into consideration in Chinese children under 6 years in 2013. The data were from a nationally representative cross-sectional survey in mainland China in 2013, which consists of 32,276 eligible records. Birth weight data and

Maternal and Fetal Outcomes After Interferon Exposure During Pregnancy: A Systematic Review With Meta-Analysis.

Interferon (IFN) treatment is widely applied in viral hepatitis and multiple myeloproliferative diseases. However, there is considerable controversy on how to deal with unintended pregnancy during IFN treatment, even selective termination is suggested by hepatologists. To settle this clinical dilemma, we conducted a systematic review to retrieve all published articles involving IFN exposure during pregnancy up until March 31, 2021. Only 8 case reports that were relevant with outcomes of pregnant women with viral hepatitis exposed to IFN-α were retrieved, and 17 studies reporting pregnancy outc

BACKGROUND: A greater understanding of the risk factors for spontaneous preterm birth and the importance of risk stratification to guide interventions has led to the introduction of preterm birth prevention clinics. AIM: To evaluate the experience and outcomes of the first specialised preterm birth clinic in New Zealand. MATERIALS AND METHODS: This observational study reviewed pregnancies cared for in a preterm birth clinic from 2013 to 2018. Cases were identified and data collected from a maternity database and electronic medical records. Analysis was by referral type. RESULTS: A total of

Combined effects of antenatal corticosteroids and surfactant supplementation on the outcome of very low birth weight infants.

Antenatal corticosteroids in preterm pregnancy may result in the reduction of the incidence of respiratory distress syndrome (RDS) and neonatal mortality. It is well known that postnatal use of surfactant in very low birth weight (VLBW) infants with RDS results in decreased neonatal morbidity and mortality. To evaluate the additive beneficial effects of combined antenatal corticosteroids and postnatal use of rescue surfactant on the outcome of VLBW infants, we retrospectively reviewed 286 maternal/infant charts of preterm infants with gestational ages 23 to 32 weeks and birth weights 501 to 15

Effects of Levothyroxine Treatment on Fertility and Pregnancy Outcomes in Subclinical Hypothyroidism: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Subclinical hypothyroidism, defined by elevated thyrotropin (TSH) and normal free thyroxine levels, is associated with adverse pregnancy outcomes, including preterm birth, pre-eclampsia, and small for gestational age. Despite the uncertainty regarding the effectiveness of levothyroxine (LT4) treatment on pregnancy outcomes in subclinical hypothyroidism, LT4 is widely administered with a pre-treatment threshold TSH level of 2.5 mU/L. The aim of this study is to investigate the efficacy of periconceptional LT4 treatment for subclinical hypothyroidism, including TSH levels >2.5 mU/L,

Tailoring clinical management after embryo transfer using β-hCG levels in resource-limited settings.

Cleavage-stage embryo transfers are often the best option for patients with limited oocytes or low fertilization rates due to medical or financial constraints. This study analyzed 424 women undergoing β-hCG testing 14 days after embryo transfer at a tertiary care center in India. Pregnancy outcomes were classified as no live births (biochemical pregnancies, ectopic pregnancies, miscarriages) or live births (single/multiple births). Higher β-hCG levels were associated with greater chances of live birth but also an increased risk of complications like preterm birth and preeclampsia, particularly

Season of birth is associated with multiple sclerosis and disease severity.

BACKGROUND: The latitude gradient in multiple sclerosis incidence indicates that low sun exposure and therefore vitamin D deficiency is associated with multiple sclerosis risk. OBJECTIVE: Investigation of the effect of month of birth, which influences postnatal vitamin D levels, on multiple sclerosis risk and severity in Sweden. METHODS: Patients and population-based controls were included from three nationwide cohorts. Differences in month of birth between cases and controls were analyzed using logistic regression and examined for effect modification by calendar year and geographic region a

[Customized and non-customized French intrauterine growth curves. I - Methodology].

OBJECTIVES: We developed intrauterine growth references, called EPOPé curves, in line with recommendations for screening of intra-uterine growth restriction issued in 2013 by the French College of Obstetricians and Gynecologists. POPULATION AND METHODS: Using the French Perinatal Survey (FPS) 2010, we adapted the methodology developed by Gardosi (1) to model intrauterine growth and its distribution and (2) to adjust for physiological fetal and maternal factors influencing fetal weight. Based on this model, 3 reference curves (unadjusted, adjusted for fetal sex, and adjusted for fetal sex, and

Perineal trauma and postpartum perineal morbidity in Asian and non-Asian primiparous women giving birth in Australia.

OBJECTIVES: To describe the postpartum perineal morbidity of primiparous women who had a vaginal birth and compare outcomes between Asian and non-Asian women in the first 2 days following the birth and at 6 and 12 weeks postpartum. DESIGN: Data from a randomized clinical trial of a perineal management technique (perineal warm packs) were used to address the study objective. SETTING: Two maternity hospitals in Sydney, Australia. PARTICIPANTS: Primiparous women who had a vaginal birth in the trial were included (n=697). One third of the women were identified as "Asian." RESULTS: Compared wit

Does the initial surgery for necrotizing enterocolitis matter? Comparative outcomes for laparotomy vs. peritoneal drain as initial surgery for necrotizing enterocolitis in infants <1000 g birth weight.

PURPOSE: Quantify short-term outcomes associated with initial surgery [laparotomy (LAP) vs. peritoneal drain (PD)] for necrotizing enterocolitis (NEC) in extremely-low-birth-weight (ELBW) infants. METHODS: Using the Children's Hospitals Neonatal Database, we identified ELBW infants <32 weeks' gestation with surgical NEC (sNEC). Unadjusted and multivariable regression analyses were used to estimate the associations between LAP (or PD) and death/short bowel syndrome (SBS) and length of stay (LOS). RESULTS: LAP was the more common initial procedure for sNEC (n = 359/528, 68%). Infants receiving

Perinatal outcomes of singletons following vitrification versus slow-freezing of embryos: a multicenter cohort study using propensity score analysis.

STUDY QUESTION: Is embryo vitrification associated with a higher risk of adverse perinatal outcomes than slow-freezing? SUMMARY ANSWER: Embryo vitrification was not associated with increased risks of adverse perinatal outcomes of pre-term birth (PTB), low birthweight (LBW), small for gestational age (SGA), large for gestational age (LGA) and macrosomia, as compared to slow-freezing. WHAT IS KNOWN ALREADY: Vitrification is becoming a widely adopted technology for embryo cryopreservation with higher embryo survival rate and live birth rate than the slow-freezing technique. However, limited dat…

Should we consider integrated approach for endometriosis-associated infertility as gold standard management? Rationale and results from a large cohort analysis.

PURPOSE: To evaluate reproductive and maternal-fetal outcomes after integrated approach for endometriosis-associated infertility (EAI). METHODS: We retrospectively analyzed reproductive and maternal-fetal outcomes of 277 women affected by EAI, subdividing patients in two groups: in the first one (surgery group), we included all women who underwent laparoscopic surgery for EAI; in the second one (integrated group), we included women who failed to conceive spontaneously after surgery within 6-12 months and underwent in vitro fertilization and embryo transfer (IVF). We evaluated delivery rate (D

Reproductive and obstetric outcome after laparoscopic excision of functional, non-communicating broadly attached rudimentary horn: a case series.

OBJECTIVE: To present the reproductive and obstetric outcome after laparoscopic excision of functional, non-communicating broadly attached rudimentary horn. STUDY DESIGN: As a part of a retrospective study performed over the past 21 years to determine the reproductive and obstetric outcome after laparoscopic treatment for symptomatic non-communicating rudimentary horn, we identified seven women who became pregnant after laparoscopic removal of the broadly attached rudimentary horn. The main outcome measures were reproductive outcome, preterm birth, mode of delivery, birth weight, pregnancy-in

Ethical aspects of cardiopulmonary resuscitation in premature neonates: where do we stand?

Advances in diagnosis, techniques, therapeutic interventions, organisation of perinatal care, and socio-economic factors have all contributed to the survival after resuscitation and intensive care of neonates with extremely low birth weight and gestational age. While morbidity during the first years of life in those infants does not increase, at school age multiple dysfunctions may become apparent. What are the limits of intensive care for the newborn? Is it right to use extreme technical and economic measures for neonates with a borderline chance of survival? What is justifiable for the neona

Implementation of Systematic Childbirth Education Through a Birth Planning Visit at a Tertiary Care Hospital in India: A Quality Improvement Project.

Background and aim Antenatal education and birth planning are essential components of respectful maternity care, improving childbirth experiences by preparing families for labor. Knowledge about prenatal exercises, birth companions, pain relief, delivery methods, and postpartum contraception empowers couples during childbirth and enhances the quality of care. Despite evidence supporting routine birth plans, our antenatal clinics lacked a formal policy for prenatal education. This study aimed to establish the practice of birth plan counseling from an existing rate of 0% and increase it to 50% w

Evaluation of possible associated factors for early childhood caries: are preterm birth and birth weight related?

BACKGROUND: This study aimed to evaluate the oral and dental health of preschool children aged 12-71 months living in the Eastern Anatolia Region of Turkey, and to examine the effects of low birth weight (LBW) and preterm, early term and term birth on dental caries. METHODS: 475 participants were included in the study. Intraoral examinations were performed and evaluated for the presence of early childhood caries (ECC). These values ​​are; Relationships such as age, gender, birth weight, week of birth, tooth brushing frequency, cariogenic nutrition, and parental education levels were examined.

Long-Term Cardiovascular Health After Pregnancy in Danish Women With Congenital Heart Disease. A Register-Based Cohort Study Between 1993 and 2016.

Background Little is known about the impact of pregnancy on long-term cardiovascular health in individuals with congenital heart disease (CHD). We aimed to determine if giving birth in patients with CHD is associated with higher risk of long-term cardiovascular morbidity. Methods and Results We studied a cohort of 1262 individuals with CHD giving birth (live or still) from 1993 to 2015 using Danish nationwide registers. We randomly sampled a comparison cohort matched on age of women with CHD who had not given birth at the time. We balanced the 2 cohorts on baseline demographic (eg, education)
