Maternal Characteristics and Obstetric and Neonatal Outcomes of Singleton Pregnancies Among Adolescents.

BACKGROUND Adolescent pregnancy remains a global public health issue with serious implications on maternal and child health, particularly in developing countries The aim of this study was to investigate maternal characteristics and obstetric and neonatal outcomes of singleton pregnancies among adolescents. MATERIAL AND METHODS A total of 241 adolescent women who gave birth to singletons between January 2015 and December 2015 at our hospital were included in this descriptive cross-sectional study. Data on maternal sociodemographic and obstetric characteristics as well as neonatal outcome were recorded. RESULTS Primary school education (66.0%), lack of regular antenatal care (69.7%), religious (36.7%) and consanguineous (37.0) marriage, Southeastern Anatolia hometown (34.9%) and Eastern Anatolia hometown (21.2%) were noted in most of the adolescent pregnancies, while 95% were desired pregnancies within marriage. Pregnancy complications were noted in 19.5% (preeclampsia in 5.8%) and cesarean delivery was performed in 44.8% of adolescent pregnancies. Preterm delivery rate was 27.0% (20.3% were in >34 weeks). Overall, 13.3% of neonates were admitted to neonatal intensive care unit (NICU) in the postpartum period (prematurity in 28.1%), while 25.3% were re-admitted to NICU admission in the post-discharge 1-month (hyperbilirubinemia in 55.7%). Adolescent pregnancies were associated considerably high rates of fetal distress at birth (28.7%), preterm delivery (26.9%), and re-admission to NICU after hospital discharge (25.3%). CONCLUSIONS In conclusion, our findings indicate that along with considerably high rates of poor antenatal care, maternal anemia and cesarean delivery, adolescent pregnancies were also associated with high rates for fetal distress at birth, preterm delivery, and NICU re-admission within post-discharge 1-month.

The long-term impacts of preterm birth and associated morbidities on bone health in preschool children: a prospective cross-sectional study from Turkey.

OBJECTIVE: To evaluate the impact of preterm birth on bone health in preschool children. METHODS: A total of 166 preschool children (aged 7-8 years) born preterm (n = 86, <37-week gestation) and at term (n = 80, ≥37 weeks of gestation) in our hospital were included in this prospective cross-sectional study. Data on antenatal, perinatal, and early postnatal characteristics and maternal obstetric history were obtained from medical records. Bone densitometry data including total bone mineral content (BMC), bone mineral density (BMD; total, lumbar, and femoral), z-scores, and bone loss were collected for each participant. RESULTS: Current height, weight, and BMI values were significantly lower in the preterm group (p < .001). Serum calcium, phosphorus and alkaline phosphatase (ALP) levels did not differ among groups, whereas VitD3 levels were significantly higher in the preterm group (p = .039). The mean total BMC, total BMD, lumbar (L2-L4) BMD, femur BMD, total z-score, and L2-L4 z-score values were significantly lower for the preterm group, whereas the total, lumbar, and femoral bone loss were significantly higher (p < .001), regardless of the severity of prematurity. Intraventricular hemorrhage (IVH) and retinopathy were significantly associated with lower total BMC (p = .004, p = .012, respectively). Fortified breastfeeding was associated with lumbar bone loss (p = .043), and formula feeding was associated with both femur and lumbar bone loss (p = .006, p = .012, respectively). CONCLUSIONS: Our findings revealed long-term adverse effects of preterm birth on bone health, with significantly lower anthropometric values (weight, height, and BMI), lower scores for total BMC, BMD (total, lumbar, femoral), and z-scores (total, femur), along with higher bone loss (total, lumbar, femoral) and higher rates of osteopenia and osteoporosis in preschool children born preterm (whether moderate or very preterm) compared with those born at term. Exclusive breastfeeding appears to reduce the likelihood of long-term bone loss in preterm infants.

Purified protein derivative response in juvenile idiopathic arthritis.

OBJECTIVE: To examine the purified protein derivative (PPD) response that develops depending upon Th1 immune response in children with juvenile idiopathic arthritis (JIA). METHODS: PPD skin test was performed in 115 children with JIA who were vaccinated with bacillus Calmette-Guerin (BCG), and then they were compared to the PPD response of 45 healthy children of the same age who were vaccinated with BCG. Children with a PPD induration > or = 5 mm were accepted as PPD-positive. PPD induration > or = 10 mm was accepted as a limit for suspecting tuberculosis. RESULTS: PPD induration size and PPD positivity rates (PPD > or = 5 mm) of children with JIA were significantly lower than those of healthy children. The mean of PPD induration size was significantly lower (p < 0.0001) in patients with either 1 BCG vaccine (3.7 +/- 3.6) or more than 1 BCG vaccine than controls with either 1 BCG vaccine (7.10 +/- 3.2) or more than 1 BCG vaccine (10.05 +/- 4.1). PPD was positive in 35.9% of patients with JIA vaccinated once (n = 32), in 50% of patients with JIA vaccinated more than once (n = 13), in 82.1% of controls vaccinated once (n = 23), and in 88.2% of controls vaccinated more than once. This result was statistically significant (patients, p = 0.03; controls, p = 0.039). It was determined that neither the activity of the disease nor the use of corticosteroid and methotrexate affected the PPD response. CONCLUSION: The response to PPD, which is one of the Th1 cell-type responses, was significantly lower in BCG-vaccinated children with JIA compared to healthy children.
