morphine and Obesity

To characterize pregnancies in which meconium-stained amniotic fluid (MSAF) was incidentally discovered during elective caesarean delivery (CD), and to evaluate the association with adverse neonatal outcomes.. A retrospective study was performed on all patients who underwent elective CD with singleton pregnancies between March 2011 and June 2020. Data analyzed included maternal, pregnancy, and neonatal characteristics. A comparison was made between pregnancies with clear amniotic fluid, MSAF, and thick MSAF.. During the study period, 10 445 patients with singleton pregnancies underwent elective CD. Of them, 368 (3.5%) had MSAF and 31 (0.3%) had thick MSAF. Patients with MSAF gained more weight during pregnancy and suffered more from diabetes compared with patients with clear fluid. Significantly more pregnancies with MSAF had either oligohydramnios or polyhydramnios. Pregnancies in the thick-MSAF group had more intrahepatic cholestasis of pregnancy. No differences were found between the groups in the composite adverse neonatal outcome, including 5-min Apgar score, need for mechanical ventilation, and admission to the neonatal intensive care unit.. The incidental finding of MSAF during elective CD is not associated with increased risks of adverse neonatal outcomes.

To investigate the effect of pre-pregnancy obesity on maternal and newborn microbiomes and fetal growth.. Individuals who gained body weight in accordance with the recommendations during pregnancy and normal gestastional age are included in the study and were separated into two groups, normal (. The stool samples of mothers who were obese before pregnancy harbored a higher (59.9 versus 52.3%) relative abundance of Firmicutes and a lower (7.1 versus 4.1%) relative abundance of Proteobacteria than the stool samples of mothers with normal body weight pre-pregnancy. In contrast, in the meconium samples of mothers who were obese pre-pregnancy, compared to those of mothers who had a normal body weight pre-pregnancy, the phylum Firmicutes was less (56.0 versus 69.0%) abundant and Proteobacteria (9.0 versus 8.5%) was more abundant. There was a negative correlation between pre-pregnancy BMI, birth weight, weight/height ratio and alpha diversity indices (Shannon and Chao1).. Pre-pregnancy obesity can affect pregnant and newborn gut microbiota, which might related to fetal growth of the newborn.

Prenatal and neonatal environmental factors, such as nutrition, microbes and toxicants, may affect health throughout life. Many diseases, such as allergy and impaired child development, may be programmed already in utero or during early infancy. Birth cohorts are important tools to study associations between early life exposure and disease risk. Here, we describe the study protocol of the prospective birth cohort, 'Nutritional impact on Immunological maturation during Childhood in relation to the Environment' (NICE). The primary aim of the NICE cohort is to clarify the effect of key environmental exposures-diet, microbes and environmental toxicants-during pregnancy and early childhood, on the maturation of the infant's immune system, including initiation of sensitisation and allergy as well as some secondary outcomes: infant growth, obesity, neurological development and oral health.. The NICE cohort will recruit about 650 families during mid-pregnancy. The principal inclusion criterion will be planned birth at the Sunderby Hospital in the north of Sweden, during 2015-2018. Questionnaires data and biological samples will be collected at 10 time-points, from pregnancy until the children reach 4 years of age. Samples will be collected primarily from mothers and children, and from fathers. Biological samples include blood, urine, placenta, breast milk, meconium, faeces, saliva and hair. Information regarding allergic heredity, diet, socioeconomic status, lifestyle including smoking, siblings, pet ownership, etc will be collected using questionnaires. Sensitisation to common allergens will be assessed by skin prick testing and allergic disease will be diagnosed by a paediatrician at 1 and 4 years of age. At 4 years of age, the children will also be examined regarding growth, neurobehavioural and neurophysiological status and oral health.. The NICE cohort has been approved by the Regional Ethical Review Board in Umeå, Sweden (2013/18-31M). Results will be disseminated through peer-reviewed journals and communicated on scientific conferences.

Obesity is critically important to maternal and fetal health during the perinatal period. We have detected an increasing prevalence of maternal obesity in recent years and investigated its complications during pregnancy.. A total of 931 pregnant females were investigated between March 2012 and March 2013. The patients were divided into four groups: body mass index (BMI) < 18.5 kg/m(2) was underweight, 18.5-24.9 kg/m(2) was normal weight, 25-29.9 kg/m(2) was overweight and ≥30 kg/m(2) was obese. The effects of obesity on fetal and maternal outcomes were investigated.. Significant increases in pregnancy-induced hypertension, gestational diabetes mellitus, cesarean delivery, premature rupture of membranes, shoulder dystocia, meconium-stained amniotic fluid, abnormal heart rate pattern and postpartum infection rates were found in the obese group during the perinatal period. Adverse maternal effects in obese cases were significantly more frequent than those in normal-weight cases. Preterm birth, perinatal mortality, low APGAR scores, newborn intensive care unit requirement, hypoglycemia and macrosomia rates were significantly higher in obese cases than those in non-obese cases. However, low birth weight infant rate was higher in the low BMI cases than that in the other BMI categories (p < 0.01).. We conclude that obesity is an important factor associated with pregnancy complications and the increase in maternal-fetal morbidity and mortality.

Obesity is a public health problem and is increasing in all populations, including pregnant women. It influences maternal and neonatal outcomes; however, data are scarce in developing countries. We aimed to compare perinatal results between obese and non-obese pregnant women in a low-risk maternity.. Transversal study of 1,779 40-week-pregnancies from 2005 to 2009 that completed a standard questionnaire with sociodemographic, obstetrical and neonatal variables and performed an ultrasound with amniotic fluid index (AFI) measurement and foetal vitality (FBP, non-stress test). They were analysed about their association with obesity on pregnancy.. When compared with non-obese women, the group of obese patients had higher systolic (118.1 vs 109.2 mmHg; p < 0.01) and diastolic (76.6 vs 70.4 mmHg; p < 0.01) pressure levels, AFI (12.52 vs. 9.61 cm; p = 0.02), presence of meconium on labour (20.52 vs. 14.67%; p = 0.02), birthweight (3602 vs. 3437 g; p < 0.01) and caesarean section (39.74 vs. 29.98%, p < 0.01).. Labour induction before 40 weeks in the antenatal period associated with foetal weight estimation should be considered as a recommendation for decreasing high percentages of caesarean delivery found in obese women.

To investigate the determinants of Group B streptococcus (GBS) maternal colonization, as well as factors associated with its vertical transmission.. Case-control study on all singletons pregnancies delivered beyond at least 24 weeks of amenorrhoea in Southern Reunion maternities for which GBS screening was known. Multiple logistic regression analysis using 2004-2007 dataset of South Reunion birth registers.. Out of 17,430 women delivered between 1st January 2004 and 31st December 2007, 2911 (16.7%) carried GBS. In a model adjusted on antenatal care, risk groups for GBS carriage were the women indigenous from another island of the Indian Ocean than Reunion (OR: 1.29, CI95%: 1.05-1.57) and obese women (body mass index ≥ 30, OR: 1.19, CI95%: 1.03-1.18). Protective factors included birthplace in mainland France (OR: 0.82, CI95%: 0.69-0.97) and underweight (OR: 0.81; CI95%: 0.69-0. 95). In a model controlling for a composite obstetrical variable delineating the protective roles of C-section and antibioprophylaxis as well as the putative role of meconium-stained fluids (thin, thick or fetid), all previously found in our setting, three key factors were independently associated with GBS vertical mother-to-child transmission: obesity (OR: 1.48, CI95%: 1.05-2.09), fetal tachycardia (OR: 4.92, CI95%: 2.79-8.68) and late preterm birth (35 to 36 wks, OR: 2.14, CI95%: 1.32-3.45).. These findings strengthen the putative roles of corpulence and ethnicity in GBS acquisition previously found in the United States, while confirming an authentic role of obesity in its vertical transmission, independently of other classical cofactors lighted by our study.

The study was designed to investigate obstetric risk factors and pregnancy outcome of patients with pruritic urticarial papules and plaques of pregnancy (PUPPP).. A population-based study comparing all pregnancies of women with and without PUPPP was conducted. Deliveries occurred during the years 1988-2002 at the Soroka University Medical Center. A multivariable logistic regression model was constructed in order to find independent risk factors associated with PUPPP.. During a 15-year period, 159 197 deliveries took place. PUPPP complicated 42 (0.03%) of all pregnancies. Using a multivariable analysis, the following conditions were significantly associated with PUPPP: multiple pregnancies (odds ratio (OR) = 4.9, 95% confidence interval (CI) 1.7-14.1), hypertensive disorders (OR = 2.2, 95% CI 1.1-4.7), and induction of labor (OR = 7.6, 95% CI 4.0-14.5). Higher rates of 5-minute Apgar scores lower than 7 (OR = 8.0, 95% CI 4.4-14.9) and of cesarean deliveries (OR = 2.9, 95% CI 1.5-5.6) were noted in the PUPPP as compared to the comparison group. While investigating other perinatal outcome parameters such as oligohydramnios, intrauterine growth restriction, meconium-stained amniotic fluid and perinatal mortality, no significant differences were observed between the groups.. Pruritic urticarial papules and plaques of pregnancy is a condition significantly associated with multiple pregnancies, hypertensive disorders, and induction of labor. Perinatal outcome is comparable to pregnancies without PUPPP.

We sought to compare obstetric and neonatal complications among great-grand multiparous, grand multiparous, and multiparous women.. One hundred thirty-three great-grand multiparas, 314 grand multiparas, and 2195 multiparas who were delivered of their infants between 1988 and 1998 were selected for the study. To facilitate comparison, the patients were all >35 years old and had similar socioeconomic characteristics.. The incidence of malpresentation at the time of delivery, maternal obesity, anemia, preterm delivery, and meconium-stained amniotic fluid increased with higher parity, whereas the rate of excessive weight gain and cesarean delivery decreased. Compared with grand multiparas, great-grand multiparas had significantly elevated risks for abnormal amounts of amniotic fluid, abruptio placentae, neonatal tachypnea, and malformations but lower rates of placenta previa (P <.05). The incidence of postpartum hemorrhage, preeclampsia, placenta previa, macrosomia, postdate pregnancy, and low Apgar scores was significantly higher in grand multiparas than in multiparas, whereas the proportion of induction, forceps delivery, and total labor complications was significantly lower than in the multiparous group (P <.05). Similar frequency of maternal diabetes, infection, uterine wall scar rupture, variations in fetal heart rate, fetal death, and neonatal mortality was found in the 3 groups.. Both high-parity groups have their own risk factors, but the rate of some complications decreases with higher parity. In addition, perinatal mortality remains low in these patients, and therefore, under satisfactory socioeconomic and health care conditions, high parity should not be considered dangerous.
