Prevalence and the factors associated with microalbuminuria among patients with type 2 diabetes mellitus and/or hypertension in the urban areas of Puducherry district: a cross-sectional study.

BACKGROUND: Microalbuminuria is an early indicator for renal and cardiovascular diseases, especially among patients with diabetes mellitus (DM) and hypertension (HTN). We determined the prevalence and the factors associated with microalbuminuria among patients with type 2 DM and/or HTN in the urban areas of the Puducherry district in India. METHODS: We included 225 patients aged 40-69 years with DM and/or HTN from a non-communicable diseases (NCDs) survey conducted during 2019-2020 in the urban areas of Puducherry district. The prevalence of microalbuminuria and various biological risk factors of NCDs were assessed as per the WHO STEPS methodology. The prevalence of microalbuminuria was presented as proportions (95% CI), and the adjusted prevalence ratio (aPR) was estimated using weighted forward stepwise generalized linear modelling. P-value ≤0.05 was considered statistically significant. RESULTS: The mean (SD) age of the patients was 54 (11) years. Over one-third (38.2%) (95% CI: 31.6-44.4) of patients with DM and/or HTN had microalbuminuria. The prevalence was highest among those having both DM and HTN 48% (95% CI: 37-59), followed by those having only DM 40.6% (95% CI: 29-52.2) and only HTN 27.7% (95% CI: 18.1-38.6). The prevalence of microalbuminuria was twice (aPR = 2.1, 95% CI: 1.1-3.9) higher among women and 2.4 times (95% CI: 1.12-5.1) higher among those having both DM and HTN as compared to those with only HTN. CONCLUSION: The prevalence of microalbuminuria among patients with DM and/or HTN is concerningly high. Population-based screening for microalbuminuria, especially among women and those having both DM and HTN, needs to be undertaken in the urban areas of Puducherry district.

Microalbuminuria serves as an early indicator for kidney and cardiovascular diseases, especially among patients with diabetes mellitus (DM) and hypertension (HTN). Our study focussed on determining the prevalence of microalbuminuria among individuals with type 2 DM and/or HTN in the urban areas of the Puducherry district in India. We included 225 patients aged 40­69 years with DM and/or HTN who participated in a non-communicable diseases (NCDs) survey conducted during 2019­2020 in urban Puducherry. We found that over one-third (38.2%) of patients with DM and/or HTN had microalbuminuria. The prevalence was highest among those having both DM and HTN (48%), followed by those having only DM (40.6%) and only HTN (27.7%). The prevalence of microalbuminuria was 2.1 times higher among women than men and 2.4 times higher among individuals with both DM and HTN compared to those with only HTN. These findings highlight the concerningly high prevalence of microalbuminuria among patients with DM and/or HTN in the urban areas of Puducherry district. To address this issue, it is crucial that the public health authorities of Puducherry district implement population-based screening initiatives for microalbuminuria, particularly targeting women and individuals with both DM and HTN in the urban areas of the Puducherry district.

Negative impact on bone homeostasis in postmenopausal women with non-metastatic breast cancer during cytotoxic chemotherapy.

INTRODUCTION: The burden and mechanisms of endocrine therapy-related bone loss are well known, while there are limited data on chemotherapy-induced bone resorption. The study aimed to evaluate the effect of cytotoxic chemotherapy on bone homeostasis among postmenopausal women with non-metastatic breast cancer. MATERIALS AND METHODS: Early and locally advanced postmenopausal non-metastatic breast cancer patients aged 45 to 65 planned for three cycles of anthracycline and four cycles of taxane chemotherapy administered along with dexamethasone (cumulative dose-256 mg) as an antiemetic from June 2018 to December 2021 were included. Bone mineral density (BMD), bone turnover markers, calciotropic hormones, pro-inflammatory cytokines, oxidative stress, and total antioxidant levels (TAS) were measured. RESULTS: We recruited 109 patients, with early 34 (31.2%) and locally advanced breast cancer 75 (68.8%) with median age 53 (45-65) years. There was a significant decrease in the % BMD at the lumbar spine, neck of the femur, and total hip post-chemotherapy. There was a significant increase in serum C-terminal telopeptide of type I collagen (CTX) and procollagen type I N-terminal propeptide (PINP) levels post-chemotherapy. PINP/CTX ratio significantly decreased post-chemotherapy. Serum 25-OH vitamin D was significantly reduced with a compensatory increase in plasma iPTH levels. The change in CTX, PINP/CTX ratio, 25-OH vitamin D, iPTH, and oxidative stress index was more pronounced during anthracycline as taxane chemotherapy. There were no significant changes in pro-inflammatory cytokine levels. CONCLUSION: Chemotherapy and dexamethasone as antiemetic resulted in significant bone loss, as evidenced by bone turnover markers. Further studies are required to understand the mechanism of chemotherapy-induced bone loss and the need for bone-strengthening agents during chemotherapy.

Increased vascular risk factors, atherosclerosis, and psychological distress among Indian adults with refractory epilepsy in comparison to well-controlled epilepsy.

OBJECTIVE: Comparison of cardiovascular risk factors, atherosclerosis, and psychological distress among adults with refractory versus well-controlled epilepsy. METHODS: The cross-sectional study consisted of two groups of 40 people each: Group I - People with well-controlled epilepsy, Group II - People with refractory epilepsy. Age- and gender-matched people of 20-50 years were recruited. People who were diabetic, smokers, hypertensive, alcoholic, pregnant, with infections, and lactating women were excluded from the study. Biochemical parameters, fasting glucose, lipid profile, fasting insulin, leptin, adiponectin, Lp[a], hsCRP, TyG INDEX, HOMA1-%S, HOMA1-IR, HOMA1-%B, QUICKI, FIRI, AIP, AC, CLTI, MLTI, CRI-I, CRI-II, and CIMT were estimated. Stress levels [PSS-10, GAD-7 & PHQ-9] were assessed based on the scoring system from the questionnaires. RESULTS: The existence of metabolic syndrome, levels of triglycerides, TyG index, MDA, OSI, CIMT, AIP, and stress scores [PSS-10, GAD-7 & PHQ-9] were significantly higher in the refractory-epilepsy group in comparison to the well-controlled group. There were associations between LDL -C and CIMT as well as between GAD-7 and CIMT among all the study subjects. There were no significant differences in the levels of glucose homeostasis parameters, hsCRP, leptin, adiponectin, and Lp[a] between the two groups. Based on the ROC analysis, MDA [AUC = 0.853] and GAD-7 [AUC = 0.900] are useful in the differential diagnosis of the study groups. CONCLUSION: People with refractory epilepsy had increased levels of vascular risk factors, atherosclerosis, and stress levels compared to people with well-controlled epilepsy. Suitable disease management and therapeutic approaches to address cardiovascular and psychological distress could be planned out among people with refractory epilepsy to improve their quality of life.

High prevalence of abdominal obesities and metabolically unhealthy individuals in a highly urbanized district of India: findings of a cross-sectional survey in Puducherry.

BACKGROUND: Abdominal obesities are better markers for predicting cardiovascular abnormalities than risk stratification based only on body mass index (BMI). We aimed to estimate the prevalence of abdominal adiposities using predictive equations for Asian Indian adults and to determine the prevalence of metabolically healthy subjects among those overweight/obese and with normal BMI. METHODS: A community-based survey was conducted among those aged 18-69 years in the district of Puducherry between February 2019 and February 2020. We surveyed 2,560 individuals selected through multi-stage cluster random sampling from urban and rural areas (50 wards and 50 villages, respectively) of the district. Anthropometric measurements, such as height, weight, waist circumference, and blood pressure were recorded from each participant. Fasting blood sample was collected from each alternate participant to estimate metabolic risk factors. RESULTS: Over four-fifths (85.6%; 95% CI: 84.2-86.9) and two-thirds (69.7%; 95% CI: 67.9-71.6) of the population in the district had high levels of intra-abdominal adipose tissue (IAAT) and total abdominal fat (TAF), respectively. Both the risk factors were significantly higher among women and urban population. About 43% (95% CI: 41-44.9) of the population had high abdominal subcutaneous adipose tissue (SCAT) with a significantly higher prevalence among the urban population. Among those overweight/obese (n = 773), almost all 99.4% (95% CI: 98.7-99.9) were metabolically unhealthy. Among subjects with normal BMI (n = 314), only about 2.9% (95% CI: 1.3-4.8) were metabolically healthy. CONCLUSION: We highlight the substantially high prevalence of IAAT, TAF, and SCAT in the district of Puducherry. Almost all the study population was metabolically unhealthy irrespective of their BMI levels.

The distribution of abdominal fat is a better predictor of cardiovascular abnormalities in an individual than the risk assessment based only on body mass index (BMI). We conducted a community-based cross-sectional survey to estimate the prevalence of abdominal adiposities using predictive equations for Asian Indian adults and determine the prevalence of metabolically healthy subjects among those overweight/obese and with normal BMI. We surveyed 2,560 adults aged 18­69 years in the district of Puducherry between February 2019 and February 2020. We recorded each participant's anthropometric measurements, such as height, weight, waist circumference, and blood pressure and collected a fasting blood sample to assess their metabolic health status. Over four-fifths (85.6%) and two-thirds (69.7%) of the population in the district had high levels of intra-abdominal adipose tissue (IAAT) and total abdominal fat (TAF), respectively. Nearly half (43%) of the population had high abdominal subcutaneous adipose tissue (SCAT). Both the risk factors were substantially higher among women and the urban population. Among those overweight/obese, almost all (99.4%) were metabolically unhealthy; among those with normal BMI, only about 2.9% were metabolically healthy. From this study, we highlight the immediate need for population-based health promotion interventions, especially among women and urban residents of Puducherry district.

Association of Umbilical Cord Serum Oxidative Stress Markers, ADMA and Adiponectin with Adverse Fetal Outcomes in Hypertensive Disorders of Pregnancy.

BACKGROUND: Limited studies are available on fetal oxidative stress and endothelial dysfunction and their association with adverse fetal outcomes in hypertensive disorders of pregnancy (HDP). Method: Umbilical cord blood samples were collected at delivery from 134 pregnant women with HDP and 59 controls. Markers of oxidative stress, endothelial dysfunction and inflammation and adipokines were analyzed. Results were correlated with adverse fetal outcomes. Results: Malondialdehyde, total antioxidant status(TAS), ADMA and hsCRP levels were increased in late and early onset preeclampsia. Adiponectin levels were decreased in early onset preeclampsia. High ADMA levels were positively associated with preterm births and fetal mortality and high TAS, protein carbonyl content(PC), ADMA and low adiponectin levels were positively associated with low birth weight babies. Conclusion: Fetal systemic oxidative stress, endothelial dysfunction and inflammation were altered in early and late onset preeclampsia. High TAS, PC and ADMA levels and low adiponectin levels were positively associated with adverse fetal outcomes in HDP.

MicroRNA Expression in Neonates with Late-onset Sepsis - A Cross-sectional Comparative Study.

BACKGROUND: Neonatal sepsis is a major health concern among neonates with higher morbidity and mortality rate. Studies have recently speculated the importance of differential expression of circulating mature micro-RNAs (miRNAs) which could serve as diagnostic as well as prognostic markers for risk of mortality in neonatal sepsis. This study aimed to analyze the expression pattern and to assess the diagnostic/prognostic value of miRNAs miR-21, miR-29a miR-31, miR-146a, and miR-155 in late-onset neonatal sepsis. METHODS: A cross-sectional comparative study was conducted including 42 healthy controls and 42 neonates with late-onset neonatal sepsis. SYBR green-based miScript RT-PCR assay was used for the expression analysis and the comparative Ct method 2-delta (Ct) method was used for relative quantification of the candidate miRNAs in plasma. Significantly higher expression of miR-21 and miR-155 and lower expression of miR-29a and miR-146a was observed in cases compared to control except miR-31. In subgroups analysis, miR-21(p = .03) showed a significant difference between pre-term and term neonates and miR-31 (p = .01) and miR-155 (p = .03) showed a significant difference between low-birth-weight and normal-birth-weight neonates. miR-146a showed significantly lower expression in the non-survivor group compared to the survivor group (p = .005). A receiver operating characteristic curve (ROC) analysis of miR-21 and miR-29a (0.829 and 0.787 AUC of ROC curves) showed good discrimination for the identification of sepsis from non-sepsis neonates. CONCLUSION: The current study shows evidence of differential expression of miRNAs in neonatal sepsis and this altered expression of candidate miRNAs could be involved in immune dysregulation, thus leading to sepsis-related severity in newborns.

Performance of WHO updated cardiovascular disease risk prediction charts in a low-resource setting - Findings from a community-based survey in Puducherry, India.

BACKGROUND AND AIM: The World Health Organization has revised the cardiovascular disease (CVD) risk prediction charts in 2019 for each of the 21 Global Burden of Disease regions. These charts (non-lab and lab versions) estimate the total CVD risk in an individual, of which the non-lab is for low-resource settings. We aimed to estimate the burden of ten-year risk of fatal or non-fatal CVD event in the district of Puducherry in India using 'non-lab' and 'lab' versions of WHO CVD risk prediction charts, and to evaluate the agreement between them. METHODS AND RESULTS: We included 710 individuals aged 40-69 years who participated in a district wide non-communicable diseases survey conducted in Puducherry, India, during 2019-20. Both charts use information on age, gender, systolic blood pressure and smoking status. Additionally, lab-chart requires individual's status on diabetes mellitus and total cholesterol while non-lab requires body mass index. Population in different CVD risk levels was presented using proportions (95% confidence intervals). Agreement between lab and non-lab charts was evaluated using Cohen's Kappa (k). The lab and non-lab charts estimated 3% (95% CI: 1.7-4.2) and none of the population respectively, to have high risk (≥20%) for fatal or non-fatal CVD event over the next ten years. Both the charts showed 89.4% (95% CI:87.2%-91.7%) concordance in CVD risk prediction indicating a good level of agreement (k = 0.653). CONCLUSION: WHO updated CVD risk prediction charts are feasible to apply when data is available and there is good agreement between non-lab and lab based charts.

Maternal Adverse Outcomes in Hypertensive Disorders of Pregnancy and Their Association with Serum Adiponectin and Redox Markers.

Background: Premature termination of pregnancy because of unmanageable maternal complications in hypertensive disorders of pregnancy (HDP) results in adverse neonatal outcome. Identification of biochemical derangements associated with maternal complications may help in the better medical management of the mother resulting in better neonatal outcomes. Method: Healthy pregnant women (C); pregnant women with gestational hypertension (GH), and preeclampsia (late [LP] and early [EP] onset) were studied. Maternal serum redox markers and adipokines were evaluated for their association with maternal complications. Results: Adiponectin levels were significantly raised in preeclampsia groups when compared with control and GH groups. Univariate and multivariate analysis confirmed that malondialdehyde (MDA) and total antioxidant status (TAS) were associated with eclampsia; adiponectin and TAS with HELLP syndrome; adiponectin, MDA and TAS with severe preeclampsia; and adiponectin with impaired renal function. Conclusion: We identified that increased serum adiponectin, MDA, and TAS were associated with adverse maternal outcomes.

Effect of cytotoxic chemotherapy on bone health among breast cancer patients. Does it require intervention?

BACKGROUND: Breast cancer (BC) is one of the most common malignancies worldwide. Although the burden and mechanisms of endocrine therapy-related bone loss are known, the evidence is scanty regarding the impact of cytotoxic chemotherapy on bone health. We have attempted to summarize the effect of cytotoxic chemotherapy on bone health in BC patients. METHODS: A comprehensive literature search was performed via MEDLINE and Cochrane library databases to evaluate the effect of chemotherapy on bone health among women with BC. We included articles related to skeletal-related events, bone mineral density, bone turnover markers, osteoporosis-specific quality of life, bisphosphonate, and other bone-directed therapy. We excluded articles that included patients with metastatic breast cancer and patients receiving hormonal therapy. DISCUSSION: Bone microenvironment in cancer is directly or indirectly influenced by clinical, hormonal, nutritional, and treatment factors. Calcitonin, parathyroid hormone, calcitriol, and estrogen are the major hormonal regulators. Bone turnover markers, namely bone formation and resorption markers, have been used to predict bone loss, fracture risk, and monitoring treatment response. Chemotherapeutic drugs such as anthracyclines and taxanes synergistically affect BMD and quality of life. Calcium, vitamin D, bisphosphonates, and denosumab are supplemented to prevent excess bone resorption. Bone-targeted anti-resorptive agents have been studied as potential anticancer agents in the adjuvant treatment of breast cancer. CONCLUSION: This review summarizes the negative effect of chemotherapy on bone health of BC patients and the importance of preventing or treating bone loss.

Quercetin modulates NRF2 and NF-κB/TLR-4 pathways to protect against isoniazid- and rifampicin-induced hepatotoxicity in vivo.

Isoniazid and rifampicin are crucial for treating tuberculosis (TB); however, they can cause severe hepatotoxicity leading to liver failure. Therapeutic options are limited and ineffective. We hypothesized that prophylaxis with quercetin attenuates isoniazid- and rifampicin-induced liver injury. We randomly divided Wistar rats into seven groups (n = 6). The animals received isoniazid and rifampicin or were co-treated with quercetin or silymarin for 28 days. The protective effect of quercetin was assessed using liver function tests and liver histology. Nuclear factor erythroid 2-related factor 2 (NRF2) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathways were explored to elucidate the mechanism of action. Quercetin co-administration prevented the elevation of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and bilirubin compared with isoniazid and rifampicin treatment alone. In the histological analysis, we observed that quercetin prophylaxis lessened the severity of hepatic necrosis and inflammation compared with the anti-TB drug-treated group. Quercetin attenuated anti-TB drug-induced oxidative stress by increasing NRF2 activation and expression, boosting endogenous antioxidant levels. Additionally, quercetin blocked inflammatory mediators high mobility group box-1 (HMGB-1) and interferon γ (IFN-γ), inhibiting activation of the NF-κB/ toll like receptor 4 (TLR-4) axis. Quercetin protects against anti-TB liver injury by activating NRF2 and blocking NF-κB/TLR-4.

Effects of Three Months of Honey Supplementation on Quality of Life and Neuropathy in Type 2 Diabetic Patients.

CONTEXT: Diabetic neuropathy, a common debilitating complication of type 2 diabetes, can occur despite adequate treatment. To date, no studies have occurred on the use alternative medicine as an adjunct therapy for treating diabetic neuropathy. OBJECTIVE: The study assessed the effects of three months of honey supplementation on insulin resistance, lipid profiles, oxidant status, nerve conduction, and QOL in patients with diabetic neuropathy. METHODS/DESIGN: The research team designed a single-arm, open-label pilot study. SETTING: The study took place at the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) in Puducherry, India. PARTICIPANTS: The study included 48 patients with diabetic neuropathy at the institute, with a mean age of 58.91 ± 7.976 years. INTERVENTION: Participants took honey for three months at a dose of 0.5 gm/Kg of body weight per day. OUTCOME MEASURES: Participants completed the Neuropathy Total Symptom Score-6 (NTSS-6) questionnaire and the Norfolk QOL Diabetic Neuropathy (Norfolk QOL-DN) questionnaire at baseline and postintervention. Also, participants' glucose levels, lipid profiles, and biochemical markers were obtained and a nerve conduction study was completed at baseline and postintervention. RESULTS: A significant reduction occurred in the NTSS-6 score (P < .0001) and the Norfolk QOL-DN total score (P < .0001) from baseline to postintervention. Participants' fasting blood glucose (FBG), triglycerides (TG), and total cholesterol (TC) decreased significantly, at P = .0192, P = .0371, and P = .0049, respectively. Their malondialdehyde (MDA), and inflammatory markers interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) also decreased significantly, and MDA showed a significant correlation with neuron specific enolase (NSE). CONCLUSIONS: Three months honey supplementation reduced participants' subjective pain scores and symptoms from diabetic neuropathy and improved their QOL. However, the nerve conduction study showed that no significant change had occurred in motor velocity.

Utility of time of onset of hypertension, ADMA and TAS in predicting adverse neonatal outcome in hypertensive disorders of pregnancy.

Background: Limited studies have been conducted to evaluate the utility of indices for the prediction of the adverse neonatal outcomes in hypertensive disorders of pregnancy (HDP).Method: A total of 174 pregnant women with HDP (gestational hypertension, late onset preeclampsia, and early onset preeclampsia) and 49 controls were sampled during the third trimester. Preterm birth, low birth weight, fetal, and infant mortality and low Apgar scores were assessed.Results: Multivariate analysis confirmed systolic blood pressure (SBP), time of onset of hypertension (TOH), and total antioxidant status (TAS) as predictors of preterm births; TOH and diastolic blood pressure (DBP) to be predictors of low birth weight babies; TOH and asymmetric dimethyl arginine (ADMA) as predictors of fetal mortality and babies with low Apgar at 5 min. We found TOH as the single best predictor for adverse neonatal outcomes.Conclusion: This study identified TOH as an important predictor of most of the adverse neonatal outcomes.

Brachial artery flow-mediated dilatation and carotid intima medial thickness in pediatric nephrotic syndrome: a cross-sectional case-control study.

BACKGROUND: Children with nephrotic syndrome (NS) have hyperlipidemia, which may lead to endothelial dysfunction. This study evaluated endothelial function and structural atherosclerosis in NS children with disease duration more than 2 years, by assessment of brachial artery flow-mediated dilatation (FMD) and carotid intima medial thickness (CIMT). METHODS: This is a cross-sectional case-control study recruiting 32 subjects aged 1-13 years with NS and 32 matched controls. Clinical details, FMD and CIMT were recorded. Lipid profile and oxidative stress were also analyzed in the subjects. RESULTS: The proportionate change in FMD was significantly lower in cases (5.65 ± 6.08 %) compared to controls (15.21 ± 9.41 %) (p < 0.01). No significant differences in CIMT were observed (p = 0.383). Blood malondialdehyde was significantly higher (p = 0.006) in the cases. Overall, 25 NS children (78 %) were in remission for more than 6 months, and in them, 9 (36 %) had deranged lipid profile. On stepwise linear regression, age of the patient was found to be a determinant of FMD (model R (2) = 18.9 %, p value = 0.048). CONCLUSION: The significantly low proportionate change in FMD in NS children suggests an ongoing process of endothelial dysfunction. Further studies are needed to confirm these findings. A long-term follow-up of children with NS may be required for identification of CIMT derangements.

Effect of supplementation of water-soluble vitamins on oxidative stress and blood pressure in prehypertensives.

The objective of the study was to evaluate the effect of water-soluble vitamins on oxidative stress and blood pressure in prehypertensives. Sixty prehypertensives were recruited and randomized into 2 groups of 30 each. One group received water-soluble vitamins and the other placebo for 4 months. Further increase in blood pressure was not observed in the vitamin group which increased significantly in the placebo group at the end of 4 months. Malonedialdehyde and protein carbonylation were reduced during the course of treatment with vitamins whereas in the placebo group there was an increase in the level of malondialdehyde. In conclusion, supplementation of water-soluble vitamins in prehypertension reduces oxidative stress and its progression to hypertension.

Effect of s-methyl-L-cysteine on oxidative stress, inflammation and insulin resistance in male wistar rats fed with high fructose diet.

BACKGROUND: S-methyl cysteine (SMC) is a hydrophilic cysteine-containing compound naturally found in garlic and onion. The purpose of the present study was to investigate the protective effect of SMC on oxidative stress, inflammation and insulin resistance in an experiment of metabolic syndrome. METHODS: Male Wistar rats were divided into five groups (6 rats in each group), namely; control, control+S-methyl cysteine (SMC), high fructose diet (HFD), HFD+SMC and HFD+metformin. The 60% fructose used for 8 weeks and SMC in the dose of 100 mg/kg bw/day/rat was used in the study. The fasting glucose, insulin, insulin resistance, and tumor necrosis factor alpha and erythrocyte enzymatic antioxidants were measured. RESULTS: Increased levels of plasma glucose, insulin, malondialdehyde, tumor necrosis factor-alpha, and insulin resistance and decreased levels of glutathione, glutathione peroxidase, and catalase were found in rats on a high fructose diet. Oral administration of SMC (100 mg/kg bw/day/rat) for 60 days resulted in significant attenuation of plasma glucose, insulin, tumor necrosis factor-alpha, insulin resistance and improved antioxidant enzyme activities. CONCLUSION: Oral treatment of SMC is effective in improving insulin resistance while attenuating metabolic syndrome, inflammation, and oxidative stress in male rats fed with fructose rich diet.

Identification of mistakes and their correction by a small group discussion as a revision exercise at the end of a teaching module in biochemistry.

BACKGROUND: Graduate medical students often get less opportunity for clarifying their doubts and to reinforce their concepts after lecture classes. The Medical Council of India (MCI) encourages group discussions among students. We evaluated the effect of identifying mistakes in a given set of wrong statements and their correction by a small group discussion by graduate medical students as a revision exercise. METHODS: At the end of a module, a pre-test consisting of multiple-choice questions (MCQs) was conducted. Later, a set of incorrect statements related to the topic was given to the students and they were asked to identify the mistakes and correct them in a small group discussion. The effects on low, medium and high achievers were evaluated by a post-test and delayed post-tests with the same set of MCQs. RESULTS: The mean post-test marks were significantly higher among all the three groups compared to the pre-test marks. The gain from the small group discussion was equal among low, medium and high achievers. The gain from the exercise was retained among low, medium and high achievers after 15 days. CONCLUSION: Identification of mistakes in statements and their correction by a small group discussion is an effective, but unconventional revision exercise in biochemistry.

Effect of daily zinc supplementation for 12 weeks on serum thyroid auto-antibody levels in children and adolescents with autoimmune thyroiditis - a randomized controlled trial.

OBJECTIVES: To assess the effect of daily zinc supplementation for 12 weeks on thyroid auto-antibodies - thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb), and oxidative stress in children with autoimmune thyroid disease (AITD) compared to standard therapy. METHODS: This open-labeled, parallel, randomized controlled trial was done in a tertiary care teaching institute in south India. Children aged 3-18 years with AITD were randomized to receive 25 mg elemental zinc daily for 12 weeks or standard therapy alone. The change in thyroid function tests (thyroid stimulating hormone, free T3, free T4), thyroid auto-antibody (TPOAb, TgAb) titers, oxidative stress markers (glutathione peroxidase, malondialdehyde, superoxide dismutase, and total antioxidant capacity) were compared. RESULTS: Forty children, 20 in each arm, were recruited in the study. We observed a female-to-male ratio of 7:1. Median duration of disease was 2 (0.25, 4.25) years. A total of 37 (92.5 %) children were hypothyroid, two hyperthyroid, and one euthyroid at enrolment. A total of 13 children (32.5 %) had associated co-morbidities, most commonly type 1 diabetes mellitus and systemic lupus erythematosus, three (7.5 %) each. We did not find any significant change in thyroid function tests, thyroid auto-antibody titers, and oxidative stress markers. However, the requirement of levothyroxine dose was significantly increased in the control arm, compared to the zinc group (p=0.03). Only four (20 %) children had minor adverse effects like nausea, metallic taste, and body ache. CONCLUSIONS: Zinc supplementation did not have any effect on thyroid auto-antibodies and oxidative stress. Zinc-supplemented children did not require escalation in levothyroxine dose.

Atherothrombotic Risk Factors in Patients With Rheumatoid Arthritis.

BACKGROUND: The onset of cardiovascular complications has increased the mortality rate in rheumatoid arthritis (RA) patients. Presently, there is a need to diagnose cardiovascular co-morbidity in rheumatic disease. While biomarkers such as P-selectin glycoprotein ligand-1 (PSGL-1), fibrinogen, anti-thrombin III (AT-III), hsCRP, lipoprotein (a) (lp(a)), leptin, adiponectin, and asymmetric dimethyl arginine (ADMA) are already established as independent risk factors for the development of atherosclerosis, the association of these biomarkers with disease activity in RA patients is unclear. METHODS: The case-control study comprised 40 cases along with age- and gender-matched controls recruited from a tertiary care hospital in southern India. Platelet activation in plasma was analyzed by flow cytometry using CD41 per CPCY 5.5 (platelet marker) and human CD62P FITC monoclonal antibody (P-selectin marker). Other parameters were quantified through nephelometry and ELISA. The association between the risk factors and RA disease severity, as per the disease activity score (DAS/DAS28), was analyzed. Furthermore, an ROC analysis was done to assess the utility of these biomarkers in the diagnosis of RA. RESULTS: With the exception of leptin, adiponectin, and ADMA, there was a significant increase in the levels of PSGL-1, fibrinogen, AT-III, hsCRP, and lp(a) when compared to healthy controls. Conventional risk factors contributing to dyslipidemia were also assessed, in which the low-density lipoprotein (LDL)/high-density lipoprotein (HDL) ratio was found to be significantly higher in RA patients compared to controls. Moreover, a significant positive correlation was identified between DAS score and activated platelets, fibrinogen, and hsCRP. ROC analysis identified that fibrinogen could predict the RA disease status with 95% accuracy, followed by activated platelets and hsCRP. CONCLUSION: Several of the studied atherothrombotic risk factors were significantly altered in patients with RA. Activated platelets, fibrinogen, and hsCRP were associated with disease activity and also served as good diagnostic predictors for RA. Based on our findings, further studies could explore the potential of introducing anti-thrombotic agents in the treatment regimen of patients with RA.

Prevalence of clustering of non-communicable disease risk factors in a highly urbanized district of India: findings of a cross-sectional survey in Puducherry.

Background: In an individual, the development and severity of Non-Communicable Diseases (NCDs) are determined by the presence or absence of clustering of NCD risk factors in them. We aimed to determine the prevalence and the factors associated with clustering of risk factors of NCDs in the district of Puducherry in India. Methodology: We conducted a community-based cross-sectional survey among the adult population (18-69 years) of Puducherry district (N = 1114) between February 2019 and February 2020. Ten risk factors of NCDs (behavioral, physical measurements and biochemical) were assessed. Individuals having ≥ 3 risk factors were regarded as having clustering of risk factors. Categorical variables are summarized using proportions (95% CI). Adjusted prevalence ratio was estimated using weighted forward stepwise generalized linear modelling. Results: Clustering of NCD risk factors was present in majority (95.2%, 95% CI: 93.8-96.3) of the population. The presence of clustering was significantly higher among women (97.1%, 95% CI: 95.9-98.3) and the urban population (97.2%, 95% CI: 96.1-98.3). The risk factors that primarily drove the high prevalence of clustering were raised salt intake and inadequate intake for fruits and vegetables in nine out of 10 people in the district. Nearly 1 in 10 (13.3%, 95% CI: 11.3-15.3), 1 in 5 (21.5%, 95% CI: 19.1-23.8) and 1 in 4 (26.8%, 95% CI: 24.1-29.4) participants had three, four and five risk factors, respectively. Conclusion: We highlight the urgent need for population-based health promotion interventions in the district of Puducherry targeting the highly prevalent NCD risk factors, especially among the women and urban populations.
