Association of pulse wave velocity and intima-media thickness with cardiovascular risk factors in young adults.

Pulse wave velocity (PWV), a measure of arterial stiffness, and intima-media thickening (IMT), a measure of early atherosclerosis, are intermediate markers of cardiovascular disease which are predictive of cardiovascular events. Traditionally, both were thought to result from accumulative exposure to traditional cardiovascular risk factors. However, their association with risk factors in young adults in low-income settings is unknown. We sought to investigate the association between PWV and IMT with traditional cardiovascular risk factors in the Andhra Pradesh Children and Parents Study cohort from Southern India. Male and female adults (N = 1440) aged between 20 and 24 years underwent measures of PWV and IMT. Exposure variables included smoking, body mass index (BMI), mean arterial pressure (MAP), glucose, homeostatic model assessment of insulin resistance (HOMA-IR), total cholesterol, high-density lipoprotein cholesterol (HDL-cholesterol), and triglycerides. Association between outcome and exposure variables was assessed using linear regression analysis. Average values for PWV and IMT were 5.9 ± 0.6 m/s and 0.5 ± 0.1 mm. In univariable analysis, PWV associated with MAP, BMI, smoking, total cholesterol, glucose, and HOMA-IR and IMT associated with MAP, BMI, tobacco use, and HDL-cholesterol. In multivariable analysis, PWV remained strongly positively associated with MAP increasing by 0.5 m/s (P < .001) for a 10 mm Hg increase in MAP (R2  = .37). In contrast, IMT negatively associated with HDL-cholesterol (β = -.10; P = .012, R2  = .02). There was weak evidence that PWV and IMT positively associated with BMI. In young adults from Southern India, PWV positively associated with blood pressure and IMT negatively associated with HDL-cholesterol. This suggests separate etiologies for atherosclerosis and arterial stiffening in young adults

Impact of COVID-19 during pregnancy on placental pathology, maternal and neonatal outcome – A cross-sectional study on anemic term pregnant women from a tertiary care hospital in southern India

BackgroundSARS-CoV-2 infection during pregnancy may cause adverse maternal, neonatal and placental outcomes. While tissue hypoxia is often reported in COVID-19 patients, pregnant women with anemia are suspected to be more prone to placental hypoxia-related injuries.MethodsThis hospital-based cross-sectional study was conducted between August-November 2021, during COVID-19 second wave in India. Term pregnant women (N=212) admitted to hospital for delivery were enrolled consecutively. Since hospital admission mandated negative RT-PCR test for SARS-CoV-2 virus, none had active infection. Data on socio-demography, COVID-19 history, maternal, obstetric, and neonatal outcomes were recorded. Pre-delivery maternal and post-delivery cord blood samples were tested for hematological parameters and SARS-CoV-2 IgG. Placentae were studied for histology.ResultsOf 212 women, 122 (58%) were seropositive for SARS-CoV-2 IgG, but none reported COVID-19 history; 134 (63.2%) were anemic. In seropositive women, hemoglobin (p=0.04), total WBC (p=0.009), lymphocytes (p=0.005) and neutrophils (p=0.02) were significantly higher, while ferritin was high, but not significant and neutrophils to lymphocytes (p=0.12) and platelets to lymphocytes ratios (p=0.03) were lower. Neonatal outcomes were similar. All RBC parameters and serum ferritin were significantly lower in anemic mothers but not in cord blood, except RDW that was significantly higher in both, maternal (p=0.007) and cord (p=0.008) blood from seropositive anemic group compared to other groups. Placental histology showed significant increase in villous hypervascularity (p=0.000), dilated villous capillaries (p=0.000), and syncytiotrophoblasts (p=0.02) in seropositive group, typically suggesting placental hypoxia. Maternal anemia was not associated with any histological parameters. Univariate and multivariate logistic regression analyses of placental histopathological adverse outcomes showed strong association with SARS-CoV-2 seropositivity but not with maternal anemia. When adjusted for several covariates, including anemia, SARS-CoV-2 seropositivity emerged as independent risk factor for severe chorangiosis (AOR 8.74, 95% CI 3.51-21.76, p&lt;0.000), dilated blood vessels (AOR 12.74, 95% CI 5.46-29.75, p&lt;0.000), syncytiotrophoblasts (AOR 2.86, 95% CI 1.36-5.99, p=0.005) and villus agglutination (AOR 9.27, 95% CI 3.68-23.32, p&lt;0.000).ConclusionAsymptomatic COVID-19 during pregnancy seemed to be associated with various abnormal placental histopathologic changes related to placental hypoxia independent of maternal anemia status. Our data supports an independent role of SARS-CoV-2 in causing placental hypoxia in pregnant women

Comorbidities associated with non- healing of plantar ulcers in leprosy patients.

BackgroundNon-healing plantar ulcers are one of the significant causes of disability in leprosy patients. Plantar ulcers often take months or years to heal, affecting the patient's quality of life. Presence of comorbid conditions in these patients can delay wound healing. The study aimed to evaluate the role of associated comorbid conditions as risk factors in ulcer healing.Methodology/principal findingsA total of 66 leprosy patients with plantar ulcers registered at LEPRA Society-Blue Peter Public Health and Research Center (BPHRC), Hyderabad, India from June 2018 to June 2019 were studied. Comprehensive clinical assessment was done, including screening for comorbid conditions and treated as per the recommended guidelines. About two-thirds of the participants were aged 50 and above, of which more than half were illiterates, and 93.5% were living below the poverty line. Majority of ulcers were seen on the forefoot; with the head of meta-tarsal bone 27 (41.6%) as the commonest site, followed by calcaneum 23 (38.3%) and great toe 10 (16.6%). Mean ulcer depth was 0.61 (0.57) cm, the area was 5.24 (6.73) cm2 and ulcer volume was 4.72 (14.33) cm3. Ulcer dimensions were significantly associated with low body mass index, hypertension and smoking.Conclusions/significanceIdentifying the risk factors delaying wound healing and detailed assessment of ulcers are of profound importance to predict the outcome of plantar ulcers in leprosy patients. The study findings indicate the need for better policies by the leprosy control program for the comprehensive management of plantar ulcers

Utilization of maternal health services by the migrant population living in the non-notified slums of Hyderabad city, India

Background: Despite increase in accessibility and utilization of maternal health services in the state of Telangana, penetration of these services in vulnerable communities is inadequate. Aims & Objectives: To understand the determinants of utilization of reproductive health services by migrant population living in non-notified slums of Hyderabad city in the Indian state of Telangana. Material & Methods: It is a community based cross sectional study of 761 rural to urban internal migrant mothers with a child of less than 2 years of age residing for a period minimum of 30 days and not more than 10 years. Information was collected for socio demographic details, antenatal care and child delivery. Results: Mothers receiving at least 4 antenatal care visits and institutional deliveries in migrants was 69.6% and 69% respectively, compared to 85.8% and 97% in general population of Hyderabad city. The likelihood of mothers receiving adequate care is 6.7 times higher in mothers with secondary education compared to formal education. The likelihood of institutional delivery is 7.8 times higher in mothers availing adequate antenatal care versus inadequate care and 2.2 times higher in mothers with secondary education versus formal education. Conclusion: Utilization of antenatal care services and promotion of institutional deliveries can be improved by acting on the supply side barriers such as health care infrastructure and demand side barriers such as indirect consumer costs, financial constraints and community engagemen

Comparison of Janani Suraksha Yojana (JSY) and augmented Arogya Laxmi scheme (ALS) in improving maternal and child health outcomes in urban settlements of Hyderabad, South India

Abstract Background India accounts for the largest number of global neonatal deaths with around 20 per 1000 live births. To improve the utilization of government services for institutional deliveries, Augmented Arogya Laxmi Scheme (ALS) was launched in Telangana state of southern India. This study assessed the effectiveness of the Janani Suraksha Yojana (JSY), which combines cash assistance with delivery and post-delivery care, in comparison to ALS in improving the outcomes related to antenatal, natal, and postnatal care in urban settlements of Hyderabad, Telangana, southern India. Methods This was a two-year cross-sectional study conducted in 14 urban settlements of Hyderabad city from September 2017- August 2019. All mothers delivered during the 18 months preceding the survey were enrolled after a written informed consent. Field investigators collected data on variables related to socio-demographic characteristics, awareness, and utilization of JSY and ALS programs. Variables related to antenatal history, antenatal care, complications during birth, delivery outcomes, newborn care, and postnatal care till 28 days were assessed. We used multivariable logistic regression model to examine the association between the different maternal, child, and socio-demographic characteristics of the two study groups. Results A total of 926 mothers were beneficiaries of Janani Suraksha Yojana (JSY) program while 933 mothers were beneficiaries of augmented Arogya Laxmi Scheme (ALS). Mothers in ALS group (AOR 1.71; 95% CI 1.21–2.43) were at increased odds of having more than eight antenatal care (ANC) visits compared to the mothers availing JSY. Mothers in ALS group were at decreased odds of having complications like severe pain in the abdomen (AOR 0.43; 95% CI 0.22–0.86), swelling of legs or feet (AOR 0.59; 95% CI 0.44–0.80) compared to mothers in JSY group. Children of mothers in the ALS group had increased odds of receiving breastfeeding within 30 minutes of birth (AOR 1.46; 95% CI 1.13–1.88) compared to children of mothers in JSY group. Conclusions The newly launched augmented ALS led to the increased utilization of the government health facilities and improved the maternal and child health outcomes

Is the Association between Vitamin D and Cardiovascular Disease Risk Confounded by Obesity? Evidence from the Andhra Pradesh Children and Parents Study (APCAPS).

BACKGROUND: Evidence of an association between serum vitamin D and cardiovascular disease risk is inconsistent and comes predominantly from studies in high-income settings. We assessed the association between serum levels of 25-hydroxyvitamin D3 (25(OH)D) and cardiovascular disease risk factors in a population of young Indian adults. METHODS: Cross-sectional analyses of data from APCAPS (Andhra Pradesh Children and Parents Study); a prospective birth cohort study in rural south India. Participants were 1038 (40.3% females) adults aged 18-24 years. Main outcome measures were blood pressures, fasting serum lipids (cholesterols and triglycerides), fasting glucose, insulin, measures of arterial stiffness (aortic augmentation index and aortic pulse wave velocity (aPWV)), carotid intima-media thickness, body mass index (BMI) and body fat (dual X-ray absorptiometry). RESULTS: Vitamin D deficiency (≤20ng/ml) was observed in 41.1% of this lean (mean BMI: 19.5) and active (mean minutes of moderate or vigorous physical activity per day: 186) population. Vitamin D deficiency was associated with higher median body fat in both males (15.9% body fat in vitamin D deficient males vs. 14.6% in non-deficient males, p<0.05) and females (29.1% body fat in vitamin D deficient females vs. 27.8% in non-deficient females, p<0.05) but no associations were observed between vitamin D deficiency and mean BMI or median fat mass index (FMI). Except a weak inverse association with fasting insulin in males, there was no clear association between serum vitamin D levels and cardiovascular disease risk factors in fully adjusted models. CONCLUSIONS: We did not find clear evidence for an association between serum vitamin D levels and cardiovascular disease risk factors. Our results, consistent with the limited evidence from randomised trials of vitamin D supplementation and Mendelian randomisation experiments, suggest that the postulated link between serum vitamin D and cardiovascular disease may be non-causal. Instead, it may be attributable to confounding by lifestyle factors such as obesity and physical inactivity which may provide more fruitful targets for cardiovascular disease prevention

Maternal Nutrition, Body Composition and Gestational Weight Gain on Low Birth Weight and Small for Gestational Age—A Cohort Study in an Indian Urban Slum

Maternal nutritional status and care during pregnancy are essential for adequate birth weight. In this prospective cohort study (N = 1061) in an urban slum, we investigated the association of maternal anthropometry, body composition, gestational weight gain and dietary intakes with low birthweight (LBW, 2) and another 30% were overweight/obese. The mean age and BMI were 23 years and 21.7 kg/m2, respectively, and haemoglobin was 10.73 g/dL. The mean birthweight (N = 605) was 2.81 ± 0.5 kg, and the average gestational age was 38 ± 2 weeks. About 15% of infants had LBW, and 48% were small for gestational age (SGA). Maternal body composition was assessed by skinfold thickness (SFT) in all trimesters. In the first trimester (N = 762), we found that mean fat-free mass (FFM), fat mass (FM) and body fat percentage (% BF) were 38.86 kg, 11.43 kg and 21.55%, respectively. Low birthweight was significantly associated with preterm deliveries (p p = 0.02) in the third trimester. Among other factors were age (p = 0.017), maternal anthropometry (height: p = 0.031; weight: p = 0.059) and fewer antenatal check-ups (p = 0.037). Small size (SGA) was consistently associated with maternal bodyweight at all trimesters (term I, p = 0.013, term II, p = 0.003 and term III, p p p = 0.003)

Viewpoints from the national consultation on addressing acute malnutrition on mainstreaming community-based program for management of acute malnutrition in India

High burden of acute malnutrition among children less than 5 years is a major public health problem in India. A ”Two-days National Consultation on Addressing Acute Malnutrition” was organized to gather experiences and evidence from 13 states of India on prevention and management of acute malnutrition among children and documenting viewpoints from experts and government counterparts on the same. The consultation centered around five key themes of addressing acute malnutrition: 1) capacity building, 2) strengthening screening, 3) nutritional care of wasting, 4) tracking progress, and 5) scale-up. The paper highlights the experiences and key recommendations around the above key themes. It emerged that there is a need to further accelerate the efforts toward strengthening existing platforms and services to address acute malnutrition among children. Regular trainings of the frontline workers, increased convergence, regular monitoring, and continued service delivery during the pandemic should be undertaken for better outcomes
