Strengthening breast cancer screening program through health education of women and capacity building of primary healthcare providers.

Background: Globally and in India, breast cancer is a prevalent malignancy. India saw 178,361 new cases and 90,000 deaths in 2020. Timely detection is vital, highlighting the importance of Breast Self-Examination (BSE), especially in low-income settings. Strengthening BSE in awareness and screening efforts is urgent. Despite awareness, practical application lags due to women's reluctance. Effective execution demands partnerships, a multi-sectoral strategy, and training grassroots workers. Objective: To address these challenges, the present study aims to strengthen the breast cancer screening program using BSE strategy and adopting a referral mechanism for the diagnosis and treatment of suspect cases. Methods: A community-based study occurred in specific districts of Rajasthan (2017-2022), enhancing breast cancer screening for women aged 30-65. It involved healthcare providers and local women, utilizing tools like the MT-DM-GP6620 Breast Inspection Model, educational booklets, and semi-structured schedules. The strategy encompassed knowledge assessment, capacity building for healthcare providers, BSE training, increasing women's breast cancer awareness, suspect case referrals, and phone-based follow-up. Results: Our study encompassed 157,225 women aged 30-65 in Jodhpur, Jalore, and Pali districts. Initial breast self-examination (BSE) awareness was below 1%. BSE training reached 218,978 women using booklets and demonstrations, with 72% aged 30-65 and the rest 15-30. Follow-ups reinforced BSE, leading to 745 identified suspect breast cancer cases, mostly due to painless lumps (332 cases). Capacity-building workshops involving 824 medical and paramedical staff strengthened early breast cancer detection in Jodhpur and Jalore, in collaboration with the district health department. Conclusion: The study model's success suggests its applicability in other Rajasthan districts, Indian states, and global breast cancer prevention programs. While positive outcomes were evident, challenges related to culture, cost, and benefits warrant consideration. The approach prioritized early detection through community engagement, reducing patient and government burdens. Community involvement and healthcare engagement were pivotal, with breast self-examination proving effective for enhancing awareness and early detection. Promoting BSE education can significantly enhance breast cancer awareness and early detection.

Serum Trace Elements in Children with Well-Controlled and Drug Refractory Epilepsy Compared to Controls: An Observational Study.

Background: Trace elements have been implicated in pathogenesis of epilepsy. Studies till date have shown altered levels of serum trace elements in children with epilepsy. Objective: The objective of the current was to estimate serum levels of trace elements in children with well-controlled and drug refractory epilepsy and compare it with controls. Methodology: In a tertiary care teaching hospital of North India, serum selenium, copper, zinc, and iron were estimated in well-controlled and drug refractory epileptic children aged 2-12 years and compared with age and gender matched controls. Results: A total of 106 children with epilepsy (55 drug refractory and 51 well controlled) and 52 age and gender matched controls were included in the study. Serum selenium and copper were significantly decreased in cases compared to controls. After classifying epilepsy into well-controlled and drug refractory cases, only in the latter the significant difference for serum selenium and copper levels remained compared to controls. Additionally, in the drug refractory cases, serum iron levels were significantly reduced compared to controls. Conclusions: Serum trace elements are altered in children with epilepsy (more so in the drug refractory group) compared to controls. Monitoring of serum trace elements in children with epilepsy should be considered. Up to one-third of epilepsy is drug refractory of which only another third are amenable to surgery. It is worth investigating the therapeutic potential of altered micronutrient status in these patients.

Seroprevalence of Dengue Infection Using IgG Capture ELISA in India, 2017-2018.

We conducted a nationally representative population-based survey in 60 districts from 15 Indian states covering all five geographic regions during 2017-2018 to estimate the age specific seroprevalence of dengue. Of the 12,300 sera collected, 4,955 were positive for IgG antibodies against dengue virus using IgG Indirect ELISA indicating past dengue infection. We tested 4,948 sera (seven had inadequate volume) positive for IgG antibodies on indirect ELISA using anti-dengue IgG capture ELISA to estimate the proportion of dengue infections with high antibody titers, suggestive of acute or recent secondary infection. Of the 4,948 sera tested, 529 (10.7%; 95% CI: 9.4-12.1) were seropositive on IgG capture ELISA. The proportions of dengue infections with high titers were 1.1% in the northeastern, 1.5% in the eastern, 6.2% in the western, 12.2% in the southern, and 16.7% in the northern region. The distribution of dengue infections varied across geographic regions, with a higher proportion of infections with high antibody titer in the northern and southern regions of India. The study findings could be useful for planning facilities for clinical management of dengue infections.

Immunity against diphtheria among children aged 5-17 years in India, 2017-18: a cross-sectional, population-based serosurvey.

BACKGROUND: Diphtheria is re-emerging as a public health problem in several Indian states. Most diphtheria cases are among children older than 5 years. In this study, we aimed to estimate age-specific immunity against diphtheria in children aged 5-17 years in India. METHODS: We used residual serum samples from a cross-sectional, population-based serosurvey for dengue infection done between June 19, 2017, and April 12, 2018, to estimate the age-group-specific seroprevalence of antibodies to diphtheria in children aged 5-17 years in India. 8309 serum samples collected from 240 clusters (122 urban and 118 rural) in 60 selected districts of 15 Indian states spread across all five geographical regions (north, northeast, east, west, and south) of India were tested for the presence of IgG antibodies against diphtheria toxoid using an ELISA. We considered children with antibody concentrations of 0·1 IU/mL or greater as immune, those with levels less than 0·01 IU/mL as non-immune (and hence susceptible to diphtheria), and those with levels in the range of 0·01 to less than 0·1 IU/mL as partially immune. We calculated the weighted proportion of children who were immune, partially immune, and non-immune, with 95% CIs, for each geographical region by age group, sex, and area of residence (urban vs rural). FINDINGS: 29·7% (95% CI 26·3-33·4) of 8309 children aged 5-17 years were immune to diphtheria, 10·5% (8·6-12·8) were non-immune, and 59·8% (56·3-63·1) were partially immune. The proportion of children aged 5-17 years who were non-immune to diphtheria ranged from 6·0% (4·2-8·3) in the south to 16·8% (11·2-24·4) in the northeast. Overall, 9·9% (7·7-12·5) of children residing in rural areas and 13·1% (10·2-16·6) residing in urban areas were non-immune to diphtheria. A higher proportion of girls than boys were non-immune to diphtheria in the northern (17·7% [12·6-24·2] vs 7·1% [4·1-11·9]; p=0·0007) and northeastern regions (20·0% [12·9-29·8] vs 12·9% [8·6-19·0]; p=0·0035). INTERPRETATION: The findings of our serosurvey indicate that a substantial proportion of children aged 5-17 years were non-immune or partially immune to diphtheria. Transmission of diphtheria is likely to continue in India until the immunity gap is bridged through adequate coverage of primary and booster doses of diphtheria vaccine.

Prolonged consumption of grass pea (64 g/Cu/day) along with millets and other cereals causes no neurolathyrism.

Objective: To assess the safe limit of L. sativus (grass pea) consumption along with cereals and millets.Methods: A community-based cross-sectional study was undertaken in three districts (Bilaspur, Durg and Raipur) of Chhattisgarh state. A total of 1500 households (HHs) were surveyed. A total of 360 split grass pea (SGP) samples were collected from all three districts for ?-ODAP analysis. Clinical examination was carried out for symptoms of neurolathyrism. Diet survey was done on 5769 HHs by 24hr recall method. Mean intake of different foods and nutrients were calculated. Based on food frequency questionnaire, HHs were separated into daily consumers of SGP along with its quantity consumed and that never consumed SGP.Results: The study revealed that 30 daily consuming and 89 never consuming HHs, in all the three districts. Daily SGP was consumed at an average of 64 g/Cu/day along with millets, cereals and vegetables. Whereas among the never consumers of SGP, mean intake of vegetables was higher than recommended intakes in addition to pulses. The average ?-ODAP content in SGP was 0.630 g%. The nutritional status of children <5 years and the adults was not significantly different between the daily SGP consumers and never consumers. Households in all the three districts, who consumed the SGP recipes, followed the method of washing, boiling, draining the excess water and cooking the pulse.Discussion: There were no adverse effects observed among daily consumers of grass pea (64 g/CU/day) along with millets, cereals and vegetables.

Hepatitis-B virus infection in India: Findings from a nationally representative serosurvey, 2017-18.

INTRODUCTION: India introduced a hepatitis-B (HB) vaccine in the Universal Immunization Program in 2002-2003 on a pilot basis, expanded to ten states in 2007-2008 (phase-1), and the entire country in 2011-2012 (phase-2). We tested sera from a nationally representative serosurvey conducted duing 2017, to estimate the seroprevalence of different markers of HB infection among children aged 5-17 years in India and to assess the impact of vaccination. METHODS: We tested sera from 8273 children for different markers of HB infection and estimated weighted age-group specific seroprevalence of children who were chronically infected (HBsAg and anti-HBc positive), and immune due to past infection (anti-HBc positive and HBsAg negative), and having serological evidence of HB vaccination (only anti-HBs positive). We compared the prevalence of serological markers among children born before (aged 11-17 years) and after (aged 5-10 years) introduction of HB-vaccine from phase-1 states. RESULTS: Among children aged 5-8 years, 1.1% were chronic carriers, 5.3% immune due to past infection, and 23.2% vaccinated. The corresponding proportions among children aged 9-17 years were 1.1%, 8.0%, and 12.0%, respectively. In phase-1 states, children aged 5-10 years had a significantly lower prevalence of anti-HBc (4.9% vs. 7.6%, p<0.001) and higher prevalence of anti-HBs (37.7% vs. 14.7%, p<0.001) compared to children aged 11-17 years. HBsAg positivity, however, was not different in the two age groups. CONCLUSIONS: Children born after the introduction of HB vaccination had a lower prevalence of past HBV infection and a higher prevalence of anti-HBs. The findings of our study could be considered as an interim assessment of the impact of the hepatitis B vaccine introduction in India.

Burden of dengue infection in India, 2017: a cross-sectional population based serosurvey.

BACKGROUND: The burden of dengue virus (DENV) infection across geographical regions of India is poorly quantified. We estimated the age-specific seroprevalence, force of infection, and number of infections in India. METHODS: We did a community-based survey in 240 clusters (118 rural, 122 urban), selected from 60 districts of 15 Indian states from five geographical regions. We enumerated each cluster, randomly selected (with an Andriod application developed specifically for the survey) 25 individuals from age groups of 5-8 years, 9-17 years, and 18-45 years, and sampled a minimum of 11 individuals from each age group (all the 25 randomly selected individuals in each age group were visited in their houses and individuals who consented for the survey were included in the study). Age was the only inclusion criterion; for the purpose of enumeration, individuals residing in the household for more than 6 months were included. Sera were tested centrally by a laboratory team of scientific and technical staff for IgG antibodies against the DENV with the use of indirect ELISA. We calculated age group specific seroprevalence and constructed catalytic models to estimate force of infection. FINDINGS: From June 19, 2017, to April 12, 2018, we randomly selected 17 930 individuals from three age groups. Of these, blood samples were collected and tested for 12 300 individuals (5-8 years, n=4059; 9-17 years, n=4265; 18-45 years, n=3976). The overall seroprevalence of DENV infection in India was 48·7% (95% CI 43·5-54·0), increasing from 28·3% (21·5-36·2) among children aged 5-8 years to 41·0% (32·4-50·1) among children aged 9-17 years and 56·2% (49·0-63·1) among individuals aged between 18-45 years. The seroprevalence was high in the southern (76·9% [69·1-83·2]), western (62·3% [55·3-68·8]), and northern (60·3% [49·3-70·5]) regions. The estimated number of primary DENV infections with the constant force of infection model was 12 991 357 (12 825 128-13 130 258) and for the age-dependent force of infection model was 8 655 425 (7 243 630-9 545 052) among individuals aged 5-45 years from 30 Indian states in 2017. INTERPRETATION: The burden of dengue infection in India was heterogeneous, with evidence of high transmission in northern, western, and southern regions. The survey findings will be useful in making informed decisions about introduction of upcoming dengue vaccines in India. FUNDING: Indian Council of Medical Research.

Current scenario of consumption of Lathyrus sativus and lathyrism in three districts of Chhattisgarh State, India.

Lathyrism is a disease caused by excessive consumption of grass pea, Lathyrus sativus especially under conditions of severe drought. Grass pea contains 3-N-oxalyl-L-2, 3-diaminopropanoic acid (ß-ODAP) a putative neurotoxin which acts through excitatory mechanism causing Neurolathyrism. Due to awareness of the disease, availability of food and levels of consumption of L. sativus there is reduction in lathyrism cases where higher consumption of L. sativus is reported in India. The present study was undertaken with the objective to assess the current scenario of consumption of L. sativus, incidence of cases of lathyrism, ß-ODAP, protein and amino acids content in L. sativus pulse collected from three districts (Bilaspur, Durg and Raipur) of Chattisgarh state. For this purpose, a total of 17,755 (13,129 rural and 4626 urban) individuals from 151 villages and 60 wards from urban area were covered for clinical examination. Out of total 5769 households (HHs) covered during the survey, 1602 HHs were cultivators, 1791 HHs non-cultivators and 2376 agricultural and other labourers. A one day 24-hour re-call diet survey was carried out in 5758 HHs (4549 rural and 1209 urban). A total of 360 split grass pea (SGP) samples were collected to estimate ß-ODAP, protein and amino acids content. Results of the study revealed that an average consumption of SGP was 20.9 gm/CU/day in Bilaspur and no consumption was reported among urban population of Raipur. Only nine old cases of lathyrism were found during the study. The mean ß-ODAP content in SGP was 0.63 ±â€¯0.14, 0.65 ±â€¯0.13 and 0.65 ±â€¯0.14 gm/100 gm, whereas the protein content was 27.0 ±â€¯2.39, 27.0 ±â€¯1.99 and 26.7 ±â€¯1.90 gm/100 gm in samples collected from Bilaspur, Durg and Raipur districts respectively. Arginine content was high in SGP and sulphur containing amino acids (cysteine and methionine) were less than other amino acids. In conclusion, the consumption of SGP was lower in these three districts with lower ß-ODAP content than earlier reports, thus the lower prevalence of lathyrism in the districts surveyed.

Micronutrient status of Indian population.

Micronutrients play an important role in the proper growth and development of the human body and its deficiency affects the health contributing to low productivity and vicious cycle of malnutrition, underdevelopment as well as poverty. Micronutrient deficiency is a public health problem affecting more than one-fourth of the global population. Several programmes have been launched over the years in India to improve nutrition and health status of the population; however, a large portion of the population is still affected by micronutrient deficiency. Anaemia, the most common form of micronutrient deficiency affects almost 50 to 60 per cent preschool children and women, while vitamin A deficiency and iodine-deficiency disorders (IDD) have improved over the years. This review focuses on the current scenario of micronutrient (anaemia, vitamin A, iodine, vitamin B12, folate, ferritin, zinc, copper and vitamin C) status in the country covering national surveys as well as recent studies carried out.

Prevention & control of fluorosis & linked disorders: Developments in the 21st Century - Reaching out to patients in the community & hospital settings for recovery.

The review on fluorosis addresses the genesis of the disease, diagnostic protocols developed, mitigation and recovery through nutritional interventions. It reveals the structural and functional damages caused to skeletal muscle and erythrocytes, leading to clinical manifestations in fluorosis. Hormonal derangements resulting in serious abnormalities in the health of children and adults are discussed. Fluoride toxicity destroys the probiotics in the gut, resulting in vitamin B12depletion, an essential ingredient in haemoglobin (Hb) biosynthesis. The article provides an overview of National Technology Mission on Safe Drinking Water and its contributions to fluorosis control. National Programme for Prevention and Control of Fluorosis is presently in operation in India and its focus cited. Major emphasis has been laid on a variety of disorders surfacing in India due to fluoride toxicity/fluorosis as 'fluorosis-linked disorders', viz. anaemia in pregnancy, schoolchildren, thyroid hormone abnormalities, hypertension, iodine deficiency disorders/goitre, renal failure and calcium+vitamin D-resistant rickets in children. The major action taken by the Indian Council of Medical Research (ICMR), Government of India in establishing a Centre of Excellence for Fluorosis Research in India and its contributions are highlighted.

Prevalence of hypovitaminosis D in India & way forward.

Deficiency of vitamin D or hypovitaminosis D is widespread irrespective of age, gender, race and geography and has emerged as an important area of research. Vitamin D deficiency may lead to osteoporosis (osteomalacia in adults and rickets in children) along with calcium deficiency. Its deficiency is linked with low bone mass, weakness of muscles and increased risk of fracture. However, further research is needed to link deficiency of vitamin D with extra-skeletal consequences such as cancer, cardiovascular disease, diabetes, infections and autoimmune disorders. The causes of vitamin D deficiency include length and timing of sun exposure, amount of skin exposed, latitude, season, level of pollution in atmosphere, clothing, skin pigmentation, application of sunscreen, dietary factors and genetic factors. The primary source is sunlight, and the dietary sources include animal products such as fatty fish, food items fortified with vitamin D and supplements. Different cut-offs have been used to define hypovitaminosis D and its severity in different studies. Based on the findings from some Indian studies, a high prevalence of hypovitaminosis D was observed among different age groups. Hypovitaminosis D ranged from 84.9 to 100 per cent among school-going children, 42 to 74 per cent among pregnant women, 44.3 to 66.7 per cent among infants, 70 to 81.1 per cent among lactating mothers and 30 to 91.2 per cent among adults. To tackle the problem of hypovitaminosis D in India, vitamin D fortification in staple foods, supplementation of vitamin D along with calcium, inclusion of local fortified food items in supplementary nutrition programmes launched by the government, cooperation from stakeholders from food industry and creating awareness among physicians and the general population may help in combating the problem to some extent.

A review of selected nutrition & health surveys in India.

Assessment of the status of health and nutrition of a population is imperative to design and implement sound public health policies and programmes. The various extensive national health and nutrition surveys provide national-level information on different domains of health. These provide vital information and statistics for the country, and the data generated are used to identify the prevalence and risk factors for the diseases and health challenges faced by a country. This review describes the various national health and nutrition surveys conducted in India and also compares the information generated by each of these surveys. These include the National Family Health Survey, District Level Household Survey, Annual Health Survey, National Nutrition Monitoring Bureau Survey, Rapid Survey on Children and Comprehensive National Nutrition Survey.

Prevalence and predictors of peripheral neuropathy in nondiabetic children with chronic kidney disease.

INTRODUCTION: This study sought to determine the prevalence and predictors of peripheral neuropathy in nondiabetic children with chronic kidney disease (CKD). METHODS: Fifty-one consecutive normally nourished children, 3-18 years of age, with CKD stages IV and V of nondiabetic etiology were enrolled from May to December 2012. Nerve conduction studies were performed in 50 children. Blood samples were analyzed for the biochemical parameters, trace elements, and micronutrients. RESULTS: The prevalence of peripheral neuropathy in our cohort was 52% (95% confidence interval 37.65, 66.34). The majority (80.8%) of the children had axonal neuropathy, and 11.5% had demyelinating neuropathy. Isolated motor neuropathy was identified in 92.3% of the children, and sensorimotor neuropathy was identified in 7.6%. The significant risk factors associated with peripheral neuropathy were older age, low serum copper, and dialysis therapy. DISCUSSION: Electrodiagnostic studies should be performed in children with CKD to assess for peripheral neuropathy for the purpose of optimizing medical care. Muscle Nerve 57: 792-798, 2018.

Validation of ICMR index for identification of dental fluorosis in epidemiological studies.

BACKGROUND & OBJECTIVES: The Indian Council of Medical Research (ICMR) formulated a Task Force on dental fluorosis and recommended the subgroup to develop a simplified index for identification and grading of dental fluorosis to be used by the health workers. This study was conducted to pre-test the 'ICMR Index for Dental Fluorosis' in the field to check its reliability and reproducibility. METHODS: A total of 600 photographs were taken, 150 in each grade of fluorosis by screening 14-17 yr school children from eight schools of Hisar (Haryana) and South west Delhi. Eighty photographs were finalized (20 in each grade) before calibration to be used for training of field workers. Calibration exercise was conducted involving the five member survey team on 100 diagnosed cases of dental fluorosis. The members again screened 74 children with dental fluorosis in the field to categorize in to different grades of fluorosis for assessment of inter-examiner reliability. RESULTS: The ICMR criteria showed more difference in agreement in very mild and mild categories during calibration. The inter-examiner reliability (κ) ranged from 0.59-1. The criteria was further modified and inter- examiner reliability (κ) found to be 0.83-0.98 which was almost perfect agreement. INTERPRETATION & CONCLUSIONS: The tool developed by the ICMR to assess dental fluorosis can be used in a field set up by non-dental personnel reliably with high degree of reproducibility.

Correlation of Serum Vitamin A Levels with Disease Activity Indices and Colonic IL-23R and FOXP3 mRNA Expression in Ulcerative Colitis Patients.

Genome-wide association studies have identified IL-23 receptor (IL-23R) as a susceptibility locus for the pathogenesis of ulcerative colitis (UC), which is characterized by exaggerated Th2/Th17 response. Studies have shown that vitamin A (VA) reduces disease progression by promoting FOXP3⁺ T cells and curbing Th17 cells. In this study, we explored the association of colonic IL-23R and FOXP3 expression in fifty-one UC patients (23 in remission and 28 with active disease) with serum VA levels and disease activity. We observed that decreased serum VA levels were associated with increased disease activity. However, there was no significant difference in mucosal IL-23R and FOXP3 expression in UC patients with moderate-to-severe disease activity compared to those in remission. Also, no significant correlation was drawn between serum VA levels and mucosal IL-23R and FOXP3 expression. Our study suggests that even after an established role of VA in inhibiting Th17 responses in mice models and humans, serum VA levels and disease activity do not correlate with FOXP3 and IL-23R expression in colonic mucosa of UC patients.

Impact of weekly iron folic acid supplementation with and without vitamin B12 on anaemic adolescent girls: a randomised clinical trial.

BACKGROUND/OBJECTIVES: In India, approx. 70% of the adolescent girls are anaemic (haemolgobin <120 g/l). The present study was a supervised randomised double-blind clinical trial conducted among adolescent girls (11-18 years) to assess and compare the impact of weekly iron folic acid (IFA) supplementation with or without vitamin B12 on reduction in the prevalence of anaemia and on blood/serum levels of haemoglobin, serum ferritin, folic acid and vitamin B12. SUBJECTS/METHODS: Community-based randomized controlled trial was carried out in Kirti Nagar slums of West Delhi. A total of 446 mild (100-119 g/l) and moderate (70-99 g/l) anaemic volunteer adolescent girls were identified and randomised into two groups. Weekly supervised supplementation was given for 26 weeks: Group A (n=222): iron (100 mg), folic acid (500 mcg) and placebo; Group B (n=224): iron (100 mg), folic acid (500 mcg) and cyanocobalamin (500 mcg for 6 weeks and 15 mcg for 20 weeks). Haemoglobin, serum ferritin, folic acid and vitamin B12 levels were assessed at baseline and after intervention. A total of 373 subjects completed 26 weeks of supplementation successfully. RESULTS: The mean haemoglobin increased from 106.7±11.2 g/l and 108.9±8.91 g/l in Group A and Group B at baseline to 116.4±10.8 g/l (P<0.001) and 116.5±10.26 g/l (P<0.001) at post-intervention, respectively, with the reduction in the prevalence of anaemia by 35.9% in Group A and 39.7% in Group B (P>0.05). A total of 63.3% participants had deficient vitamin B12 levels (<203 pg/ml) at baseline, which reduced to 40.4% after intervention with cyanocobalamin, whereas no change was observed in vitamin B12 status in the other group. Significant reduction (P=0.01) in the prevalence of serum ferritin deficiency (<15 ng/ml) was observed in the group supplemented with vitamin B12 (from 36.5 to 6.4%) as compared with the other group supplemented with only IFA (from 39.1 to 15.2%). CONCLUSIONS: IFA supplementation with or without vitamin B12 is an effective measure to cure anaemia. Although addition of vitamin B12 had similar impact on improving haemoglobin status as IFA alone, it resulted in better ferritin status. Hence, more multi-centre studies with a longer duration of supplementation or higher dose of vitamin B12 may be undertaken to assess the possible impact of vitamin B12 on improving haemoglobin levels in the population.

Cobalamin and folate deficiencies among children in the age group of 12-59 months in India.

BACKGROUND: Anemia is a major public health problem among children under 5 years of age in India. Cobalamin and folate deficiencies play an important role in the etiology of anemia. This study was done to assess the prevalence of cobalamin and folate deficiencies among children in the age group of 12-59 months. METHODS: A community-based cross-sectional study was conducted. A total of 470 children were included. Non-fasting venous blood samples were collected from each child for the estimation of serum cobalamin and folate levels. Pattern of dietary consumption of the each child was assessed with the help of the food frequency questionnaire (FFQ) method. RESULTS: The median levels (interquartile range) of serum cobalamin (n = 469) and folate (n = 416) were found to be 275 (202-427) pg/ml and 3.02 (2.02-4.94) ng/ml, respectively. The overall prevalence of cobalamin and folate deficiencies was found to be 180/469 [38.4%; 95% Confidence Interval (CI): 34.1-42.8%] and 263/416 (63.2%; 95% CI: 58.5-67.7%), respectively. CONCLUSIONS: A high prevalence of cobalamin and folate deficiencies was found in children under 5 years of age.

Serum alpha tocopherol, vitamin B12, and folate levels in childhood acute lymphoblastic leukemia survivors with and without neuropathy.

Various micronutrients are essential for optimal functioning of the peripheral nervous system. Serum vitamin E, vitamin B12, and folic acid were estimated in childhood acute lymphoblastic leukemia survivors aged between 5 and 18 years in first continuous remission within 3 years of completion of vincristine-based chemotherapy with and without electrophysiologically defined neuropathy. A total of 80 children were studied. Neuropathy was seen in 27 (33.75%) children electrophysiologically. None of the children had vitamin E deficiency. However, the alpha tocopherol/(cholesterol + triglyceride) ratio was significantly lower in children with neuropathy (P = .05). The prevalence of folate (P = .48) and vitamin B12 (P = .21) deficiency in children with and without neuropathy was not significantly different. Thus, the prevalence of deficiencies of these micronutrients was not significantly different in childhood acute lymphoblastic leukemia survivors with or without electrophysiologically defined neuropathy.

Efficacy of early neonatal supplementation with vitamin A to reduce mortality in infancy in Haryana, India (Neovita): a randomised, double-blind, placebo-controlled trial.

BACKGROUND: Vitamin A supplementation in children aged 6 months to 5 years has been shown to reduce mortality. The efficacy of neonatal supplementation with vitamin A to reduce mortality in the first 6 months of life is plausible but not established. We aimed to assess the efficacy of neonatal oral supplementation with vitamin A to reduce mortality between supplementation and 6 months of age. METHODS: We undertook an individually randomised, double-blind, placebo-controlled trial in Haryana, India. We identified pregnant women through a surveillance programme undertaken every 3 months of all female residents in two districts of Haryana, India, aged 15-49 years, and screened every identified livebirth. Eligible participants were neonates whose parents consented to participate, were likely to stay in the study area until at least 6 months of age, and were able to feed orally at the time of enrolment. Participants were randomly assigned to receive oral capsules containing vitamin A (retinol palmitate 50,000 IU plus vitamin E 9·5-12·6 IU) or placebo (vitamin E 9·5-12·6 IU) within 72 h of birth. Randomisation was in blocks of 20 according to a randomisation list prepared by a statistician not otherwise involved with the trial. Investigators, participants' families, and the data analysis team were masked to treatment allocation. The primary outcome was mortality between supplementation and 6 months of age. Analysis included all participants assigned to study groups. This trial is registered with ClinicalTrials.gov, number NCT01138449, and the Indian Council of Medical Research Clinical Trial Registry, number CTRI/2010/091/000220. FINDINGS: Between June 24, 2010, and July 1, 2012 we screened 47,777 neonates and randomly assigned 44,984 to receive vitamin A (22,493) or placebo (22,491). Between supplementation and 6 months of age, 656 infants died in the vitamin A group compared with 726 in the placebo group (29·2 per 1000 vs 32·3 per 1000; difference -3·1 per 1000, 95% CI -6·3 to 0·1; risk ratio 0·90, 95% CI 0·81 to 1·00). We noted no significant interactions between the intervention effect and sex on mortality at 6 months (p=0·409). Supplementation with 50,000 IU vitamin A within the first 72 h of life was generally safe and well tolerated, with the exception of a small excess risk of transient bulging fontanelle (205 cases in the vitamin A group confirmed by physician vs 80 cases in the placebo group, risk ratio 2·56 [95% CI 1·98-3·32]). INTERPRETATION: The findings of this study, done in a population in which vitamin A deficiency is a moderate public health problem, are consistent with a modest reduction in mortality between supplementation and 6 months of age. These findings must be viewed together with similar trials in other populations to enable determination of appropriate public health policy. FUNDING: Bill & Melinda Gates Foundation to WHO.
