ABSTRACT
BACKGROUND: Preeclampsia is a major cause of maternal, fetal and neonatal morbidity and mortality, particularly in developing countries. Considering the burden of preeclampsia and its associated complications, it is important to understand the underlying risk factors and mechanisms involved in its etiology. There is considerable interest in the potential for dietary long chain polyunsaturated fatty acids (LCPUFA) as a therapeutic intervention to prevent preeclampsia, as they are involved in angiogenesis, oxidative stress, and inflammatory pathways. METHODS: The REVAMP study (Research Exploring Various Aspects and Mechanisms in Preeclampsia) follows a cohort of pregnant women from early pregnancy until delivery to examine longitudinally the associations of maternal LCPUFA with clinical outcome in preeclampsia. A multisite centre for advanced research was established and pregnant women coming to Bharati hospital and Gupte hospital, Pune, India for their first antenatal visit are recruited and followed up at 11-14 weeks, 18-22 weeks, 26-28 weeks, and at delivery. Their personal, obstetric, clinical, and family history are recorded. Anthropometric measures (height, weight), food frequency questionnaire (FFQ), physical activity, socioeconomic status, fetal ultrasonography, and color Doppler measures are recorded at different time points across gestation. Maternal blood at all time points, cord blood, and placenta at delivery are collected, processed and stored at - 80 °C. The children's anthropometry is assessed serially up to the age of 2 years, when their neurodevelopmental scores will be assessed. DISCUSSION: This study will help in early identification of pregnant women who are at risk of developing preeclampsia. The prospective design of the study for the first time will establish the role of LCPUFA in understanding the underlying biochemical and molecular mechanisms involved in preeclampsia and their association with developmental programming in children.

AIMS/HYPOTHESIS: The Pune Children's Study aimed to test whether glucose and insulin measurements in childhood predict cardiovascular risk factors in young adulthood. METHODS: We followed up 357 participants (75% follow-up) at 21 years of age who had undergone detailed measurements at 8 years of age (glucose, insulin, HOMA-IR and other indices). Oral glucose tolerance, anthropometry, plasma lipids, BP, carotid intima-media thickness (IMT) and arterial pulse wave velocity (PWV) were measured at 21 years. RESULTS: Higher fasting glucose, insulin and HOMA-IR at 8 years predicted higher glucose, insulin, HOMA-IR, BP, lipids and IMT at 21 years. A 1 SD change in 8 year variables was associated with a 0.10-0.27 SD change at 21 years independently of obesity/adiposity at 8 years of age. A greater rise in glucose-insulin variables between 8 and 21 years was associated with higher cardiovascular risk factors, including PWV. Participants whose HOMA-IR measurement remained in the highest quartile (n = 31) had a more adverse cardiovascular risk profile compared with those whose HOMA-IR measurement remained in the lowest quartile (n = 28). CONCLUSIONS/INTERPRETATION: Prepubertal glucose-insulin metabolism is associated with adult cardiovascular risk and markers of atherosclerosis. Our results support interventions to improve glucose-insulin metabolism in childhood to reduce cardiovascular risk in later life.

Growth hormone (GH) deficiency in children manifests as short stature but is also associated with metabolic disturbances. Paucity of GH is also likely to be associated with increased intima media thickness. Data on body composition (BC) and carotid intima media thickness (cIMT) in children with growth hormone deficiency (GHD) from developing countries are very scarce. Therefore, objectives of present study were to assess effect of 1 year of rhGH therapy on (i) BC and lipid profile (LP) in a cohort of Indian GHD children and (ii) effect on atherosclerotic markers - cIMT in subsample. Anthropometry, BC [% body fat (BF), % lean body mass (LBM), bone mineral content (BMC)] (DXA) and LP were measured in 49 pre-pubertal GHD-children (9.3 ± 3.1 years) at baseline and after 1 year of rhGH therapy. On subset of 20 children, cIMT of right common carotid artery was also measured. Baseline BC parameters were compared with age-gender matched healthy controls (n = 49). At baseline % BF was 23 ± 9 %, LBM was 9 ± 3 kg and BMC was 0.306 ± 0.15 kg in GHD- children; BF was comparable, while lean and bone were less than controls (p < 0.05). Post therapy, significant reduction in fat (15%), and cIMT (7%) and increase in LBM and BMC by 40% and 44%, respectively (p < 0.05) was seen. Our cohort of untreated GHD children had abnormal BC and cIMT as compared to controls. rhGH therapy for 1 year had beneficial effect on BC and cardiovascular risk factors.

OBJECTIVE: To investigate interrelationship of arterial measurements with metabolic syndrome (MS) components and zinc status in apparently healthy Indian adults. METHODS: Anthropometry and biochemical data were recorded in 110 men and 139 women (25-50 yr). Carotid Intima media thickness (CIMT), stiffness (beta), pulse wave velocity (PWV), elasticity modulus (Ep), and arterial compliance (AC) of the right carotid artery were evaluated ultrasonically. According to definition of MS, subjects were categorized as MS-1, MS-2, MS-3. Further, normal and MS subjects were divided as zinc sufficient and deficient. RESULTS: In all, 12.1% subjects had 3 risk factors for MS. Mean CIMT, beta, Ep and PWV were significantly higher by 6%, 11.6%, 29.5% and 12.4% in subjects with MS than normal (p < 0.05). AC showed significant decline in MS subjects by only 3% than normal (p < 0.05). Serum zinc was inversely correlated with beta, Ep and PWV in both the genders in subjects with MS (p < 0.05). A synergistic effect of serum zinc deficiency with MS further envisages the elevated risk of arterial stiffness. CONCLUSION: Risk of atherosclerosis is marked by increase in stiffness parameters even in presence of a single MS risk and zinc deficiency may further aggravate the risk indicating need for early diagnosis.

OBJECTIVE: To investigate the possible association between metabolic syndrome (MS) and arterial stiffness in Indian children with parental MS status. METHODS: A cross-sectional study was conducted in 140 overweight/obese and 60 normal-weight Indian children (mean age, 11.4 ± 2.8 years) along with one of their parents during 2008-2009. Data on weight, height, blood pressure, serum lipids, zinc, insulin, and glucose were collected. Intima media thickness (CIMT) and stiffness parameters were assessed in the right carotid artery. Physical activity and diet were assessed using structured questionnaires. Body composition was measured using dual-energy x-ray absorptiometry. RESULTS: A gradual increase in the percentage of MS children with an increasing number of MS components in parents was observed. Mean values for arterial stiffness, pulse wave velocity, and elastic modulus were significantly higher in MS children of MS parents than in MS children of normal parents (p < 0.05). A significant correlation was observed for lifestyle, metabolic, and arterial parameters among child-parent pairs (p < 0.05). Multiple logistic regression revealed that children's CIMT and arterial stiffness were significantly associated (p < 0.01) with their serum levels of triglycerides, high-density lipoprotein, and zinc, as well as with parental MS-CIMT. CONCLUSION: Parental MS status and lifestyle factors increase the risk of MS and arterial abnormalities in children.

OBJECTIVE: The aim of the study was to evaluate carotid arterial stiffness and intima media thickness (IMT) in obese children in comparison with healthy children, and to examine associations of lipid profile and blood pressure with carotid artery morphology. METHODS: Anthropometric and blood parameters were assessed in 44 overweight, 95 obese (6-17 years) and 69 healthy age-matched normal children. Percent body fat was measured by dual-energy X-ray absorptiometry and stiffness and IMT of the common carotid artery were evaluated using Aloka alpha 10 equipment. RESULTS: Anthropometric and lipid parameters were significantly higher in overweight and obese than in normal children (p < 0.05). Stiffness (beta), pulse wave velocity (PWV), elastic modulus (Ep) and blood pressure were significantly higher in obese and overweight children than in normal children (p < 0.05). However, overweight and obese children did not show any significant difference in IMT compared with normal children (p > 0.1). Significant positive correlation of PWV, beta and Ep and negative correlation of arterial compliance with body fat and triglyceride was noted (p < 0.05). Different multinomial regression models for each e-Tracking parameter indicated that the relative risk of hypertension was highest with high PWV, followed by LDL cholesterol, Ep and body fat. CONCLUSION: PWV may be considered an important marker for evaluation of early functional changes of the carotid artery in children and adolescents.

OBJECTIVE: The purpose of this study was to describe fetal size on sonography in a rural Indian population and compare it with those in European and urban Indian populations. Methods. Participants were from the Pune Maternal Nutrition Study of India. Fetal growth curves were constructed from serial ultrasound scans at approximately 18, 30, and 36 weeks' gestation in 653 singleton pregnancies. Measurements included femur length (FL), abdominal circumference (AC), biparietal diameter (BPD), and occipitofrontal diameter, from which head circumference (HC) was estimated. Measurements were compared with data from a large population-based study in France and a study of urban mothers in Vellore, south India. RESULTS: Fetal AC and BPD were smaller than the French reference at 18 weeks' gestation (-1.38 and -1.30 SD, respectively), whereas FL and HC were more comparable (-0.77 and -0.59 SD). The deficit remained similar at 36 weeks for AC (-0.97 SD), FL (-0.43 SD), and HC (-0.52 SD) and increased for BPD (-2.3 SD). Sonography at 18 weeks underestimated gestational age compared with the last menstrual period date by a median of -1.4 (interquartile range, -4.6, 1.8) days. The Pune fetuses were smaller, even at the first scan, than the urban Vellore sample. CONCLUSIONS: Fetal size was smaller in a rural Indian population than in European and urban Indian populations, even in mid pregnancy. The deficit varied for different fetal measurements; it was greatest for AC and BPD and least for FL and HC.

OBJECTIVES: We investigated whether the relationship between components of height and cardiovascular disease (CVD) risk may be explained by body composition. We also examined relationships between parental heights and offspring CVD risk. DESIGN: A cohort study using cross-sectional data. SETTING: A secondary care hospital setting in Pune, India. PARTICIPANTS: We studied 357 young adults and their parents in the Pune Children's Study. Primary and secondary outcomes: we measured weight, total height, leg length, sitting height, plasma glucose, insulin and lipids, and blood pressure (BP). Total and regional lean and fat mass were measured by dual X-ray absorptiometry. RESULTS: Leg length was inversely related, and sitting height was directly related to BMI. Total height and leg length were directly related to lean mass, while sitting height was directly related to both lean and fat mass. Leg length was inversely related to systolic BP and 120 min glucose, independent of lean and fat mass. Sitting height was directly related to systolic BP and triglycerides; these relationships were attenuated on adjustment for lean and fat mass. When examined simultaneously, greater leg length was protective and greater sitting height was associated with a more detrimental CVD risk profile. CONCLUSIONS: Shorter adult leg length and greater sitting height are associated with a more adverse CVD risk factor profile. The mechanisms need further study, but our findings suggest a role for lean and fat mass.

We conducted a case matched control study to observe the adverse effects of ciprofloxacin used in neonatal septicemia We enrolled 30 neonates with multidrug-resistant septicemia who were treated with intravenous ciprofloxacin for 14 days. Thirty matched neonates with septicemia treated with other antibiotics were enrolled as controls There was no difference in the mean serum electrolytes, hepatic, renal and hematologic parameters of the two groups. Serial ultrasonographic measurements of the cartilage of the knee after 1 and 6 months showed no difference in the two groups. The femoral cartilage showed an increase of 78.8% in the mean longitudinal area after 6 months in the study group. In the control group, the femoral cartilage showed a 78.4% increase after 6 months. Similarly, the tibial cartilage showed no difference in the percentage increase in size of the study and control group at the end of 6 months. When controlled for birth weight and gestation, cartilage size was not affected by ciprofloxacin.

OBJECTIVE: To explore association of adiposity and physical activity with arterial stiffness and to propose optimal waist circumference cutoffs, corresponding to 90(th) percentile of NHANES (National Health and Nutrition Examination Survey) for Indian children and adolescents. MATERIALS AND METHODS: Data on weight, height, waist circumference, physical activity and right Carotid artery Intima-Media-Thickness (CIMT), pulse wave velocity (PWV), elasticity modulus (Ep), stiffness index(ß), arterial compliance (AC) were assessed in 250 children (72 normal-weight and 178 overweight/obese) aged 6-17 years from Pune city, India. Body composition was measured using Dual energy X-ray absorptiometry. RESULTS: Total, 37.1% normal-weight and 98.2% overweight/obese children had high adiposity (>95(th) body fat percentile). Positive association of PWV and Ep (r = 0.5) also ß(r = 0.25) with BMI (Body Mass Index), waist circumference and body fat (P < 0.05) was observed. Physical activity was inversely associated with PWV (r =-0.2), ß(r =-0.13), Ep (r =-0.12) and positively with AC (r = 0.12) (P < 0.05). PWV significantly increased with increasing body fat for each tertile of physical activity (P < 0.05). Regression analysis revealed waist circumference, BMI, body fat and physical activity as independent associates for PWV after adjusting for age (P < 0.05). The cutoff of waist circumference yielding sensitivity and specificity for predicting the risk of high PWV was (-0.43, -0.44) for boys and girls with sensitivity in boys (girls) of 78% (87%) and specificity in boys (girls) 51% (70%). The observed cutoffs are less than the NHANES-III cutoff values of waist circumference for 90(th) percentiles according to age and sex. CONCLUSION: High adiposity and low physical activity are adversely related to arterial stiffness in Indian children.
ABSTRACT
OBJECTIVE: To study the effect of lifestyle intervention in the presence of multivitamin-zinc supplementation in improving the cardiometabolic status of overweight children. MATERIALS AND METHODS: Data were evaluated in 74 overweight children (11.3 ± 2.9 years) randomly assigned to three groups of intervention for 4 months as follows: group A: diet-exercise counseling with multivitamin-zinc supplementation; group B: diet-exercise counseling; and group C: placebo. Anthropometric, biochemical, carotid arterial and lifestyle parameters were assessed. RESULTS: Lifestyle counseling resulted in significant reduction in inactivity, energy and fat intakes and increase in micronutrient density of diets and physical activity in groups A and B in comparison to group C. Percent decline in body fat was more in group A than in groups B and C. Percent change in triglycerides (-13.7%) was significantly higher in group A than in groups B (-5.9%) and C (5.7%). Pulse wave velocity and elasticity modulus reduced and arterial compliance improved significantly in group A than in group B. CONCLUSION: Multivitamin-zinc supplementation with lifestyle intervention has a positive effect of on the cardiometabolic status of overweight children.
ABSTRACT
McCune-Albright syndrome (MAS) is defined by the clinical triad of fibrous dysplasia of bone (FD), café-au-lait spots and precocious puberty (PP). It is a rare disease with estimated prevalence between 1/100,000 and 1/1,000,000. The authors report a case of MAS in an Indian boy who had history of unilateral macroorchidism (but no other signs of MAS) since birth, then presented with PP, FD and café-au-lait spots at 6 years of age. On examination he had asymmetry of the face, café-au-lait spots and signs of sexual precocity with a right testicular volume of 25 ml (left 8 ml). Investigations revealed suppressed gonadotropins with elevated testosterone levels. Skeletal survey showed dysplastic changes involving multiple bones and advanced bone age. Reports of MAS in a boy with unilateral macroorchidism are scarce. Thus, unilateral macroorchidism at birth in a baby may be a feature of MAS and should be followed up with care.

We examined the differential associations of each parent's height and BMI with fetal growth, and examined the pattern of the associations through gestation. Data are from 557 term pregnancies in the Pune Maternal Nutrition Study. Size and conditional growth outcomes from 17 to 29 weeks to birth were derived from ultrasound and birth measures of head circumference, abdominal circumference, femur length and placental volume (at 17 weeks only). Parental height was positively associated with fetal head circumference and femur length. The associations with paternal height were detectible earlier in gestation (17-29 weeks) compared to the associations with maternal height. Fetuses of mothers with a higher BMI had a smaller mean head circumference at 17 weeks, but caught up to have larger head circumference at birth. Maternal but not paternal BMI, and paternal but not maternal height, were positively associated with placental volume. The opposing associations of placenta and fetal head growth with maternal BMI at 17 weeks could indicate prioritisation of early placental development, possibly as a strategy to facilitate growth in late gestation. This study has highlighted how the pattern of parental-fetal associations varies over gestation. Further follow-up will determine whether and how these variations in fetal/placental development relate to health in later life.

The intrauterine environment has a strong influence on pregnancy outcome. The placenta and the umbilical cord together form the main supply line of the fetus. Amniotic fluid also serves important functions. These three main components decide whether there will be an uneventful pregnancy and the successful birth of a healthy baby. An insult to the intrauterine environment has an impact on the programming of the fetus, which can become evident in later life, mainly in the form of cardiovascular diseases, diabetes, and certain learning disabilities. The past two decades have witnessed major contributions from researchers in this field, who have included ultrasonologists, epidemiologists, neonatologists, and pediatricians. Besides being responsible for these delayed postnatal effects, abnormalities of the placenta, umbilical cord, and amniotic fluid also have associations with structural and chromosomal disorders. Population and race also influence pregnancy outcomes to some extent in certain situations. USG is the most sensitive imaging tool currently available for evaluation of these factors and can offer considerable information in this area. This article aims at reviewing the USG-related developments in this area and the anatomy, physiology, and various pathologies of the placenta, umbilical cord, and the amniotic fluid.
