Serum procalcitonin as a biomarker of bloodstream infection & focal bacterial infection in febrile patients.

Background & objectives: Bacteraemia is a serious form of infection in patients presenting with fever, thus, there is a necessity for a biomarker for rapid diagnosis of bacteraemia in such patients to make better therapeutic decisions. This study was conducted to measure the serum procalcitonin (PCT) levels at the time of initial presentation as a biomarker for identifying bacteraemia and as a predictor of mortality in patients admitted with acute fever. Methods: Four hundred and eighty patients, who presented with acute fever requiring admission to a tertiary care teaching hospital in south India, were prospectively studied. All patients were evaluated with a detailed history, physical examination, laboratory and imaging studies. Baseline serum PCT was measured for each patient within six hours of admission. Results: Among patients with single infectious cause (n=275), significantly higher median serum PCT levels were evident in bacteraemia compared to leptospirosis (P=0.002), dengue (P <0.001), scrub typhus (P <0.001) and evident focus of infection without bacteraemia (P=0.036). By receiver-operator characteristic curve analysis, at a cut-off value of >3.2 ng/ml, the sensitivity and specificity of serum PCT levels in predicting bacteraemia were 81.1 and 63.3 per cent, respectively. As per the worst-case scenario analysis, 91 (18.9%) patients had a poor outcome and these had significantly higher median serum PCT levels compared to survivors (n=389) [9.46 (2.03-44.4) vs. 1.23 (0.34-7.645); P <0.001]. At a cut-off value of >3.74 ng/ml, serum PCT levels at initial presentation predicted in-hospital mortality with a sensitivity and specificity of 67 and 67.5 per cent, respectively. Interpretation & conclusions: Our observations suggest that serum PCT level may be a useful biomarker for identifying bacteraemia as well as predicting mortality in patients with acute fever requiring admission to hospital.

A Randomized, Double Blind, Placebo Controlled, Crossover Study to Assess the Safety and Beneficial Effects of Cassia Tora Supplementation in Healthy Adults.

OBJECTIVE: The current clinical trial was aimed at evaluating the safety and beneficial effect of Cassia tora (C. tora) supplementation in healthy adults. DESIGN: A randomized, double blind, placebo controlled study with a crossover design was done on 60 healthy normal weight adults (age range: 20-55 yrs). The study consisted of 2 treatment phases of 24 weeks each with a washout period of 4 weeks between the phases. 30 subjects randomly allocated to the 'Placebo first' group and 30 to 'C. tora first' group and assigned to receive a dose of C. tora (330 mg) or matched placebo three times a day. Safety markers were measured at base line and at the end of both the treatment phases. Body mass index, blood pressure, fasting blood sugar, glycated hemoglobin, lipid profile and antioxidants were measured at baseline and at every three months interval. Repeated measures analysis was applied to assess the period and carryover effects of the drug over placebo on biochemistries. RESULTS: C. tora supplementation was well tolerated and no apparent changes were observed in safety markers. The net effect of C. tora in natural units over placebo was 0.83 [0.57, 1.09]- high density lipoprotein cholesterol; 27.63 [24.39, 30.88]- superoxide dismutase; 0.32 [0.28, 0.36]- catalase; 0.68 [0.56, 0.80]- glutathione peroxidase; 0.25 [0.22, 0.29]- glutathione s-transferase; 0.32 [0.29, 0.36]- glutathione and -1.08 [-1.63, -0.54]- low density lipoprotein cholesterol. CONCLUSION: The findings advocate that C. tora supplementation is safe and beneficial in elevating high density lipoprotein cholesterol and antioxidants and hence advised for consumption.

Study of the structure and functioning of referral mechanism of patients receiving treatment and records linkage under Revised National Tuberculosis Control Programme (RNTCP) of Government of India.

BACKGROUND: The reliable and successful performance of the Revised National Tuberculosis Control Programme (RNTCP) "referral mechanism" is profoundly important in the medical college scenario, and it is an important requirement of the programme to have feedback status report of the referred patients. METHODS: An observational study on tuberculosis (TB) patients referred from Directly Observed Treatment (DOT) Centre, Sri Venkateswara Institute of Medical Sciences (SVIMS) was conducted during the years 2010 to 2012 (n=622). Subjects referred to other TUs within the District but failed to report there within 45 days constituted "cases" and subjects, who obtained treatment from the TUs they were referred to "controls". The initial information or confirmation of registration for treatment status feedback were obtained from patient/Senior Treatment Supervisor (STS)/District Tuberculosis Centre (DTC) levels respectively both before using intervention (Phase I, year 2010) and after using intervention (Phase II, years 2011 and 2012) by sending day-to-day text messaging of referral details of patients to the STS and District Tuberculosis Officer (DTO). RESULTS: During Phase I, the distribution of subjects (n=242) in the ages ≤25, 26-50, and ≥51 years was similar in both the cases and control subjects (p=0.054). Further, there was no statistically significant difference in the median age of the cases and controls [34.5 (interquartile range, IQR 31-51) vs 39 (30-54); p=0.319]. There was no statistically significant difference in other parameters, such as gender distribution (p=0.9748); availability of phone numbers (p=0.9614); type of disease (p=0.8395); and type of case (p=0.0793). In Phase II, the effect of intervention on feedback related parameters showed statistically significant improvement in all the parameters such as initial feedback levels obtained within 15 days (p=0.0077); within 45 days (p<0.0001); above 45 days (p<0.0001); registration status confirmation within 45 days (p=0.0343); mismatch of feedback received by observer (p<0.0001); and telephone number of patients recorded (p<0.0001). CONCLUSION: Our findings suggest that text messaging reminders may be an important tool to achieve optimal feedback response in resource-limited settings.

Comparison of Disease Activity Score in 28 joints with ESR (DAS28), Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire Disability Index (HAQ-DI) & Routine Assessment of Patient Index Data with 3 measures (RAPID3) for assessing disease activity in patients with rheumatoid arthritis at initial presentation.

BACKGROUND & OBJECTIVES: In patients with rheumatoid arthritis (RA), disease severity assessment is done using Disease Activity Score in 28 joints with ESR (DAS28). Computing DAS28 is time-consuming, requires laboratory testing and an online calculator. There is a need to validate rapid methods of disease severity assessment for routine daily use. This study was conducted to compare DAS28, Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire Disability Index (HAQ-DI) and Routine Assessment of Patient Index Data with 3 measures (RAPID3) to assess the disease activity in patients with RA. METHODS: We prospectively studied the utility of CDAI, HAQ-DI and RAPID3 scoring in 100 consecutive newly diagnosed, disease modifying antirheumatic drugs (DMARDs) naïve adult patients with RA seen during January 2013 and June 2014 at a tertiary care teaching hospital in south India. RESULTS: The mean age of the patients was 42.1±11.6 yr, there were 82 females. The median [interquartile range (IQR)] symptom duration was 6 (range 4-12) months. The median (IQR) DAS28, CDAI, HAQ-DI and RAPID3 scores at presentation were 7 (6-7), 36 (28-43), 2 (1-2) and 17 (13-19), respectively. A significant positive correlation was observed between DAS28 and CDAI (r=0.568; P<0.001); DAS28 and HAQ-DI (r=0.304; P=0.002) and DAS28 and RAPID3 (r=0.404; P<0.001). A 'slight-to-fair' agreement was observed in between DAS28 and CDAI (kappa-statistic=0.296). The agreement between DAS28 and HAQ-DI (kappa-statistic=0.007) and RAPID3 (kappa-statistic=0.072) was less robust. INTERPRETATION & CONCLUSIONS: In adult patients with RA, in the setting where illiteracy is high, CDAI emerged as the preferred choice for rapid assessment of severity of disease at the time of initial presentation.

Provider-initiated HIV testing & counselling in incident tuberculosis cases under National TB Programme conditions at a tertiary care teaching hospital in Tirupati, south India.

BACKGROUND & OBJECTIVES: : As sparse published data are available regarding burden of human immunodeficiency virus (HIV) infection in incident tuberculosis (TB) cases at tertiary care teaching hospitals under National TB Programme conditions from India, the present study was designed to assess the proportion of referred registered TB patients who had actually undergone HIV testing and HIV-seropositivity in these. METHODS: : This was a study of provider-initiated HIV testing and counselling in patients registered for the treatment under Revised National TB Control Programme (RNTCP) of Government of India at a tertiary care teaching hospital in Tirupati, south India, during 2012-2013. RESULTS: : Between January 2012 and June 2013, 610 adult patients registered under RNTCP who were referred to Integrated Counselling and Testing Centre for HIV testing, were prospectively studied. Of these, 458 patients (75%) [mean age: 38.6±16.3 yr; 295 (64.4%) males] underwent HIV testing; HIV-co-infection was present in 21 (4.6%) patients. A significantly higher proportion of HIV co-infection was evident in PTB compared with EPTB [13/179 (7.2%) vs 8/279 (2.8%); respectively, P=0.038] and in previously treated patients compared to new patients [6/51 (11.8%) vs 15/407 (3.7%); respectively, P=0.009]. INTERPRETATION & CONCLUSIONS: : The findings of this study showed that a higher proportion of TB patients underwent HIV testing (75%) compared to the national figure of 63 per cent in 2013-2014. HIV seropositivity (4.6%) in TB patients who underwent HIV testing was similar to the five per cent figure observed at national level during 2013-2014. The HIV status of 25 per cent of patients with incident TB still remained unknown, suggesting a need for better integration and co-ordination for effective management of HIV-TB co-infection.

Binary classification using multivariate receiver operating characteristic curve for continuous data.

The classification scenario needs handling of more than one biomarker. The main objective of the work is to propose a multivariate receiver operating characteristic (MROC) model which linearly combines the markers to classify them into one of the two groups and also to determine an optimal cut point. Simulation studies are conducted for four sets of mean vectors and covariance matrices and a real dataset is also used to demonstrate the proposed model. Linear and quadratic discriminant analysis has also been applied to the above datasets in order to explain the ease of the proposed model. Bootstrapped estimates of the parameters of the ROC curve are also estimated.

Adolescent undernutrition and early adulthood bone mass in an urbanizing rural community in India.

The long-term effects on bone health of nutritional status in adolescence are unclear. The impact of adolescent and current body mass on bone mass in young adulthood in rural India was assessed. Current lean mass was a more important determinant of bone mass than thinness during adolescence in this population. PURPOSE/INTRODUCTION: Adolescence is a crucial period for skeletal growth. However, the long-term effects on bone health of nutritional status in adolescence, particularly in the context of nutritional transition, are unclear. The current manuscript assessed the impact of adolescent and current body size on bone mass in young adulthood in an Indian rural community that is undergoing rapid socioeconomic changes. METHODS: The Andhra Pradesh Children and Parents Study is a prospective cohort study in Hyderabad, India. In 2003-2005, the study collected anthropometric and cardiovascular data on adolescents (mean age = 16 years old). The second and third waves of the study in 2009-2012 collected data on current anthropometric measures, areal bone mineral density (aBMD) in hip and lumbar spine (L1-L4) measured by dual-energy X-ray absorptiometry, and living standards of the trial participants who were now young adults (mean age = 22 years old). RESULTS: The median body mass index (BMI) of the 722 participants included in this analysis was 16.8 kg/m(2) during adolescence, while the median BMI as young adults was 19.3 kg/m(2). Lower aBMD during adulthood was associated with lower adolescent BMI (ß (95 % confidence interval) for hip aBMD 0.017 (0.013 to 0.022) and LS aBMD 0.012 (0.008 to 0.016)). This association was attenuated upon adjustment for current fat and lean mass (ß (95 % CI) for hip aBMD 0.00 (-0.005 to 0.005) and LS aBMD 0.005 (0.000 to 0.01)). There was clear evidence for positive associations between aBMDs and current lean mass. CONCLUSIONS: Current lean mass was a more important determinant of bone mass than thinness during adolescence in this population. Weight gain during late adolescence and young adulthood coupled with improvement in lean mass may help to mitigate any adverse effects that pre-adulthood undernutrition may have on bone mass accrual.

Effect of oral hypoglycaemic agents on bone metabolism in patients with type 2 diabetes mellitus & occurrence of osteoporosis.

BACKGROUND & OBJECTIVES: Type 2 diabetes mellitus (T2DM) is considered to be a protective factor against development of osteoporosis. But oral hypoglycaemic agents (OHA) are likely to increase the risk of osteoporosis. This study was carried out to evaluate the effect of various OHA on bone mineral density (BMD) in patients with T2DM. METHODS: Forty one patients (study group) with T2DM (mean age 51.9±5.5 yr; 31 females) receiving treatment with oral hypoglycaemic agents (OHA) [thiazolidinediones alone (n=14) or in combination with other OHA (n=27)] for a period of at least three consecutive years and 41 age- and gender-matched healthy controls (mean age 51.4±5.1 yr) were included in the study. A detailed clinical history was taken and all were subjected to physical examination and recording of anthropometric data. BMD was assessed for both patients and controls. RESULTS: The mean body mass index (kg/m [2] ) (26.5±4.90 vs 27.3 ±5.33) and median [inter-quartile range (IQR)] duration of menopause (yr) among women [6(2-12) vs 6(1-13)] were comparable between both groups. The bone mineral density (BMD; g/cm [2] ) at the level of neck of femur (NOF) (0.761±0.112 vs 0.762±0.110), lumbar spine antero-posterior view (LSAP) (0.849±0.127 vs 0.854±0.135); median Z-score NOF {0.100[(-0.850)-(0.550)] vs -0.200[(-0.800)-(0.600)]}, LSAP {-1.200[(-1.700)-(-0.200)] vs -1.300 [(-1.85)-(-0.400)]} were also similar in study and control groups. Presence of normal BMD (9/41 vs 8/41), osteopenia (16/41 vs 18/41) and osteoporosis (16/41 vs 15/41) were comparable between the study and control groups. No significant difference was observed in the BMD, T-scores and Z-scores at NOF and LSAP among T2DM patients treated with thiazolidinediones; those treated with other OHA and controls. INTERPRETATION & CONCLUSIONS: The present findings show that the use of OHA for a period of three years or more does not significantly affect the BMD in patients with T2DM.

Subclinical atherosclerosis in patients with rheumatoid arthritis by utilizing carotid intima-media thickness as a surrogate marker.

BACKGROUND & OBJECTIVES: Patients with rheumatoid arthritis (RA) are more prone for accelerated atherosclerosis and Asian Indians as an ethnic group are predisposed to a high risk of premature atherosclerosis. However, sparse data are available regarding the burden of atherosclerosis among asymptomatic adult patients with RA in south India. We studied the burden of asymptomatic atherosclerosis in adult south Indian patients with RA at Tirupati, Andhra Pradesh, India, utilizing carotid intima-media thickness (CIMT) as a surrogate marker. METHODS: Ultrasound examination of the carotids and CIMT measurement (mm) were carried out in 32 patients with RA, 32 age- and gender-matched normal controls, and 32 patients with atherosclerosis and angiographically proven coronary artery disease. The CIMT values in patients with CAD and normal controls were used to derive the appropriate cut-off value of CIMT for defining atherosclerosis that would be applicable for the ethnic population studied. RESULTS: Patients with RA had a higher mean CIMT (mm) compared with normal control subjects (0.598 ± 0.131 vs 0.501 ± 0.081; p0 = 0.001). Carotid plaque was found more frequently among the cases compared with normal controls [5/32 (15.6%) vs 0/32 (0%), p0 =0.020]. Using this cut-off value derived by the receiver operator characteristic curve method (≥ 0.57 mm; sensitivity 84.4; specificity 90.6%) and the 75 th percentile value among normal controls (≥ 0.55 mm) as surrogate markers, the presence of subclinical atherosclerosis was significantly more among asymptomatic patients with RA compared with normal controls [(59.3 vs 12.5%; p0 <0.001) and (62.5 vs 25%; P<0.001) respectively]. INTERPRETATION & CONCLUSIONS: Based on the present findings CIMT appears to be a useful surrogate marker for detecting subclinical atherosclerosis in adult Indian patients with RA.

Socio-economic position and cardiovascular risk in rural Indian adolescents: evidence from the Andhra Pradesh children and parents study (APCAPS).

OBJECTIVES: This study examined association between socio-economic position and cardiovascular risk factors in adolescents to investigate whether childhood socio-economic position is a risk factor for future cardiovascular disease, independently of adult behaviours. STUDY DESIGN AND METHODS: Participants (n = 1128, 46% girls, aged 13-18 years) were members of a birth cohort (Andhra Pradesh Children and Parents Study or APCAPS) established to investigate long-term effects of a pregnancy and childhood nutritional supplementation trial conducted in 29 villages near Hyderabad in South India. Cross-sectional associations between socio-economic position and cardiovascular risk factors were examined using linear regression models. RESULTS: The mean BMI was 16.7 kg/m(2) for boys and 17.8 kg/m(2) for girls. Socio-economic position was positively associated with fat mass index (0.15 kg/m(2); 95% CI: 0.05-0.25) and inversely associated with central-peripheral skinfold ratio (-0.04; 95% CI: -0.06 to -0.01) and, in boys, fasting triglycerides (-0.05; 95% CI: -0.09 to -0.01). Association of socio-economic position with other risk factors (blood pressure, arterial stiffness, fasting glucose, insulin and cholesterol) was weak and inconsistent, and did not persist after adjustment for potential confounders, including age, sex, pubertal stage, height, adiposity and nutrition supplementation. CONCLUSIONS: The study thus showed that lower socio-economic position may be associated with greater central adiposity and higher triglyceride levels in these settings. Socio-economic gradient in cardiovascular risk may strengthen in future with later economic and lifestyle changes. Cardiovascular disease prevention strategies should therefore focus on the youth from the low income group.

Cohort profile: Andhra Pradesh Children and Parents Study (APCAPS).

The Andhra Pradesh Children and Parents Study (APCAPS) was originally established to study the long-term effects of early-life undernutrition on risk of cardiovascular disease. Its aims were subsequently expanded to include trans-generational influences of other environmental and genetic factors on chronic diseases in rural India. It builds on the Hyderabad Nutrition Trial (HNT) conducted in 1987-90 to compare the effects on birthweight of a protein-calorie supplement for pregnant women and children. The index children of HNT and their mothers were retraced and examined in 2003-05, and the children re-examined as young adults aged 18-21 years in 2009-10. The cohort was expanded to include both parents and siblings of the index children in a recently completed follow-up conducted in 2010-12 (N=∼6225 out of 10,213 participants). Recruitment of the remaining residents of these 29 villages (N=∼55,000) in Ranga Reddy district of Andhra Pradesh is now under way. Extensive data on socio-demographic, lifestyle, medical, anthropometric, physiological, vascular and body composition measures, DNA, stored plasma, and assays of lipids and inflammatory markers on APCAPS participants are available. Details of how to access these data are available from the corresponding author.

Is relative leg length a biomarker of childhood nutrition? Long-term follow-up of the Hyderabad Nutrition Trial.

BACKGROUND: Relative leg length is frequently used as a biomarker of childhood nutrition in epidemiological studies, but evidence is lacking. We examined the association between supplemental nutrition in pregnancy and childhood and relative proportions of components of height in adolescence. METHODS: In a community trial of nutritional supplementation, villages from adjacent administrative areas were selected to serve as intervention (n = 15) and control (n = 14) arms. In the intervention villages, balanced protein-calorie supplementation (2.51 MJ, 20 g protein) was offered daily to pregnant women and their offspring until the age of 6 years. Children born in the trial were re-examined 15 years later to assess components of height. RESULTS: A total of 1165 adolescents (intervention: 654, 49% of trial participants; control: 511, 41% of trial participants) aged 13-18 years were examined. Supplemented children were 10 mm taller [95% confidence interval (CI): 1.4 to 18.7 mm], but almost all of the increase was in trunk length (9 mm, 95% CI: 2.6 to 15.4 mm). The age- and gender-adjusted ß-coefficients for the association of nutritional supplementation with relative trunk, leg and lower leg lengths (expressed as standard deviation scores) were 0.26 (95% CI: 0.11 to 0.42), 0.08 (95% CI: -0.03 to 0.19) and 0.03 (95% CI: -0.08 to 0.15) respectively, thereby unsupportive of cephalocaudal gradient in growth. CONCLUSIONS: In this nutritional supplementation trial in an undernourished population, we were unable to confirm relative leg length as a biomarker of childhood nutrition. Alternative explanations may underlie the reported associations between childhood conditions and relative leg length.

Effect of integration of supplemental nutrition with public health programmes in pregnancy and early childhood on cardiovascular risk in rural Indian adolescents: long term follow-up of Hyderabad nutrition trial.

OBJECTIVE: To determine whether integration of nutritional supplementation with other public health programmes in early life reduces the risk of cardiovascular disease in undernourished populations. DESIGN: Approximately 15 years' follow-up of participants born within an earlier controlled, community trial of nutritional supplementation integrated with other public health programmes. SETTING: 29 villages (15 intervention, 14 control) near Hyderabad city, south India. PARTICIPANTS: 1165 adolescents aged 13-18 years. INTERVENTION: Balanced protein-calorie supplementation (2.51 MJ, 20 g protein) offered daily to pregnant women and preschool children aged under 6 years, coupled with integrated delivery of vertical public health programmes. MAIN OUTCOME MEASURES: Height, adiposity, blood pressures, lipids, insulin resistance (homoeostasis model assessment (HOMA) score), and arterial stiffness (augmentation index). RESULTS: The participants from the intervention villages were 14 mm (95% confidence interval 4 to 23; P=0.007) taller than controls but had similar body composition. The participants from the intervention villages had more favourable measures of insulin resistance and arterial stiffness: 20% (3% to 39%; P=0.02) lower HOMA score and 3.3% (1% to 5.7%; P=0.008) lower augmentation index. No strong evidence existed for differences in blood pressures and serum lipids. CONCLUSIONS: In this undernourished population, integrated delivery of supplemental nutrition with other public health programmes in pregnancy and early childhood was associated with a more favourable profile of cardiovascular disease risk factors in adolescence. This pragmatic study provides the most robust evidence to date on this important hypothesis for which classic trials are unlikely. Improved maternal and child nutrition may have a role in reducing the burden of cardiovascular disease in low income and middle income countries.

Dietary habits and effect of two different educational tools on nutrition knowledge of school going adolescent girls in Hyderabad, India.

OBJECTIVES: To assess dietary habits and nutrition knowledge levels of the adolescent girls from different schools and to study the efficacy of two different nutrition education tools in improving their nutrition knowledge in the classroom setting. DESIGN: Purposive sampling technique was adapted for selecting the subjects in the study. SETTING: Four secondary schools in Hyderabad, India. SUBJECTS: In total, 164 adolescent girls belonging to eighth grade. INTERVENTIONS: Two interventions (Intervention-1. Traditional method using print media such as folders leaflets and charts; Intervetion-2. Audio-visual CD) were carried out in a classroom setting for the experimental group. RESULTS: FFQ data on dietary consumption of adolescent girls revealed more consumption of aerated drinks, bakery items, fast foods and less consumption of millets irrespective of their socio-economic conditions. However, consumption of vegetables, green leafy vegetables and fruits was moderate. A significant improvement in the nutrition related knowledge was observed among the experimental group after interventions-1 and -2 as compared to the baseline data. However, no significant difference in the improvement of nutrition knowledge levels was observed with the second intervention over the first intervention as already the children in the experimental group gained knowledge through print media. CONCLUSIONS: Education on ill effects of aerated drinks, fast foods and the importance of nutrition during the adolescent phase should be emphasized in future programmes.

Evaluation of the Food and Agriculture Organization's global school-based nutrition education initiative, Feeding Minds, Fighting Hunger (FMFH), in schools of Hyderabad, India.

OBJECTIVE: To assess the efficacy of the Food and Agriculture Organization's global school-based nutrition education initiative, Feeding Minds, Fighting Hunger (FMFH), in improving nutrition-related knowledge levels of schoolchildren. DESIGN: Adopting the cluster randomisation technique, five schools each in experimental and control groups were randomly chosen from the member schools of a voluntary organisation. Repeated measures of knowledge levels were carried out at three points in time to assess pre-, post-intervention and retention of knowledge gained during the intervention. Children from experimental schools were given nutrition education by teachers in the classroom setting using FMFH material. SUBJECTS/SETTINGS: Schoolchildren (n=358 in the control group and n=312 in the experimental group) of grades VIII and IX from schools in Hyderabad, India. RESULTS: The classroom-based intervention resulted in a significant improvement (P<0.01) in nutrition knowledge levels of schoolchildren in the experimental group. Significant improvement in knowledge was also observed in the control group. The effect size indicated that the improvement in knowledge levels of schoolchildren in experimental schools over control schools was medium (d=0.40), indicating the efficacy of the FMFH programme in improving nutrition-related knowledge. No significant decrease (P>0.05) in knowledge levels was observed after 2 months, indicating retention of the knowledge acquired through the intervention. CONCLUSION: The FMFH programme provides an opportunity for schoolchildren to learn more about nutrition through their teachers in a classroom setting if the lesson plans are adapted to the local circumstances. Furthermore, it has the potential to make nutrition education interactive, effective and sustainable.

Effect of micronutrient supplementation on health and nutritional status of schoolchildren: growth and morbidity.

OBJECTIVE: We evaluated the effect of a micronutrient-fortified beverage on growth and morbidity in apparently healthy schoolchildren. METHODS: This was a double-blind, placebo-controlled, matched-pair, cluster, randomized study in semi-urban middle-income residential schoolchildren aged 6 to 16 y. Anthropometrics (height and weight), clinical symptoms of deficiency, and morbidity data were collected at baseline in the supplemented group (n = 446 in 10 grades) and the placebo group (n = 423 in 10 grades) and after 14 mo of supplementation (n = 355 in the supplement group and n = 340 in the placebo group from nine pairs). RESULTS: After 14 mo of supplementation, there was a significant increase in mean increments of height and weight z scores of -0.04 and 0.02, respectively, in the supplemented group compared with -0.14 and -0.09 in the placebo group. Velocity of weight (3.56 versus 3.00) was significantly (P < 0.01) higher with supplementation. Although there were no differences in the incidence of common childhood diseases such as fever, cough and cold, diarrhea, and ear infections elicited for a reference period of 1 mo at every quarterly follow-up examination, the mean duration of illness (calculated per person per year) was significantly shorter (5.0 d) in the supplemented group than in the placebo group (7.4 d). CONCLUSIONS: The micronutrient-fortified beverage was beneficial in promoting growth and decreasing duration of common illnesses among middle-class residential schoolchildren who had adequate energy and protein intakes.

Clinical profile of carcinoma stomach at a tertiary care hospital in south India.

Carcinoma of the stomach is an important cause of mortality due to cancer. Carcinoma of the stomach is common in the southern region of India. We conducted a retrospective study on the epidemiological, clinical and survival patterns among the patients with carcinoma of the stomach, attending our hospital from June 19, 1995 to 1st January 2003. All the patients had histopathological confirmation of malignancy. Patients with gastrooesophageal junction lesions were excluded. Surgery was performed with curative as well as palliative intent in suitable patients. Chemotherapy has been incorporated in to the combined modality treatment in our hospital since July 2000. Postoperative chemotherapy comprised commonly used intravenous chemotherapy regimens, while oral chemotherapy (etoposide) was given to patients with disease not amenable to surgery, and those having poor performance and nutritional status. Oral etoposide was given in a dose of 50 mg/day for 14 days, in a 28 day cycle. Quality of life was assessed in the oral chemotherapy group. Out of the 1749 cancer patients seen during the period, 151 had gastric malignancy (8.6%). The median age was 55 years (range 15-84 years). The male to female ratio was 4:1. Adenocarcinoma was found in 148 patients, 2 had stromal tumours and 1 had non-Hodgkin lymphoma. Stage disribution was as follows; stage 2-1 patient , stage 3a-25, stage3b-49, stage4-3 1, Metastatic-28. Staging was not completed in 17 patients. Eighty-nine patients underwent surgery. Fifty-nine patients (39%) did not have surgery. One patient underwent polypectomy. Curative gastrectomy was performed in 11 patients. Thirty-nine patients underwent palliative tumour resection. Palliative gastro-jejunostomy for relief of symptoms was performed in 26 patients and exploratory laparotomy alone was perforaied in 13. Thirty-eight patients received chemotherapy. Out of these, only 2 patients had prior complete resection of the tumour and 36 received palliative chemotherapy. Intravenous chemotherapy was given to 17 patients and oral chemotherapy to 19; All the patients who received oral etoposide did not experience any toxicity. Patients who received intravenous chemotherapy (n=17) had the following toxicities: grade 3 emesis in 4 (20%), discoloration of the skin and nails in 6(31%), alopecia in 8 (50%), grade 3 diarrhoea in 3 (15%) and neutropenic fever in 4 patients (20%). Median survival for the cohort was 10.4 months. Quality of life parameters, such as sleep, appetite, weight, pain, work and general sense of ill health showed improvement. In conclusion, 8.6% of all cancers at our hospital were due to cancer of stomach, in whom distal gastric tumor were more frequent and most were non-resectable. Median survival was 10.4 months. Oral etoposide was found to be safe, improved the quality of life and may play a role in the palliative management of advanced carcinoma of the stomach.
