Introduction Childhood and adolescence require adequate amount of micronutrients for normal growth and development. The primary objective of study was to assess the prevalence of deficiencies of Vitamins (Vitamin A, 25 Hydroxy Vitamin D, Vitamin B12 and Folate) and minerals (Calcium, Zinc, Selenium and Iron), among urban school going children aged 6–11 and 12–16 years in ten cities of India. Secondary objective was to find the association between micronutrient deficiencies with sociodemographic and anthropometric indicators. Methods A multi-center cross-sectional study was conducted across India. Participants in the age groups of 6 to 11 years (group 1) and 12 to 16 years (group 2) were selected from randomly chosen schools from each center. Data on socio economic status, anthropometric measures was collected. Blood samples were collected for biochemical analysis of micronutrients. Point estimates and 95% confidence intervals was used to assess the prevalence of deficiencies. Associations were observed using chi square, student t test and ANOVA test. Results From April 2019 to February 2020, 2428 participants (1235 in group 1 and 1193 group 2) were recruited from 60 schools across ten cites. The prevalence of calcium and iron deficiency was 59.9% and 49.4% respectively. 25 Hydroxy Vitamin D deficiency was seen in 39.7% and vitamin B12 in 33.4% of subjects. Folate, Selenium and Zinc were deficient in 22.2%, 10.4% and 6.8% of subjects respectively. Vitamin A deficiency least (1.6%). Anemia was prevalent in 17.6% subjects and was more common among females. Conclusion One or more micronutrient deficiencies are found in almost one half of school going children in urban area. Hence efforts must be made to combat these on priority. Trial registration number CTRI/2019/02/017783.

Dengue fever, which is spread by Aedes mosquitoes, has claimed many lives in Kerala, with the Thiruvananthapuram district bearing the brunt of the toll. This study aims to demarcate the dengue risk zones in Thiruvananthapuram district using the analytical hierarchy process (AHP) and the fuzzy-AHP (F-AHP) methods. For the risk modelling, geo-environmental factors (normalized difference vegetation index, land surface temperature, topographic wetness index, land use/land cover types, elevation, normalized difference built-up index) and demographic factors (household density, population density) have been utilized. The ArcGIS 10.8 and ERDAS Imagine 8.4 software tools have been used to derive the risk zone maps. The area of the risk maps is classified into five zones. The dengue risk zone maps were validated using dengue case data collected from the Integrated Disease Surveillance Programme portal. From the receiver operating characteristic (ROC) curve analysis and the area under the ROC curve (AUC) values, it is proved that the F-AHP method (AUC value of 0.971) has comparatively more prediction capability than the AHP method (AUC value of 0.954) in demarcating the dengue risk zones. Also, based on the comparison of the risk zone map with actual case data, it was confirmed that around 82.87% of the dengue cases occurred in the very high and high-risk zones, thus proving the efficacy of the model. According to the dengue risk map prepared using the F-AHP model, 9.09% of the area of Thiruvananthapuram district is categorized as very high risk. The prepared dengue risk maps will be helpful for decision-makers, staff with the health, and disaster management departments in adopting effective measures to prevent the risks of dengue spread and thereby minimize loss of life.

Background: The world is experiencing a pandemic of chikungunya which has swept across Indian Ocean and the Indian subcontinent. Kerala the southernmost state of India was affected by the chikungunya epidemic twice, first in 2006 and then in 2007. Kerala has got geography and climate which are highly favorable for the breeding of Aedes albopictus, the suspected vector. Aim: The aim of the study was to highlight the various domestic and environmental factors of the families affected by chikungunya in 2007 in Thiruvananthapuram district (rural) of Kerala. Settings and design: This is a cross-sectional survey conducted in Thiruvananthapuram (rural) district during November 2007. Materials and Methods: Samples were selected from field area under three Primary Health Centers. These areas represent the three terrains of the district namely the highland, midland, and lowland. The sample size was estimated to be 134 houses from each study area. The field area of health workers was selected as clusters and six subcenters from each primary health center were randomly selected (lot method). Results and Conclusions: The proportion of population affected by chikungunya fever is 39.9% (38.9-40.9%). The investigators observed water holding containers in the peri-domestic area of 95.6% of the houses. According to regression (binary logistic) analysis, the area of residence [adjusted odds ratio (OR) = 8.01 (6.06-14.60)], residing in a non-remote area [adjusted OR=0.25 (0.16-0.38)], perceived mosquito menace [adjusted OR=3.07 (2.31-4.64)], and containers/tires outside the house [adjusted OR=5.61 (2.74- 27.58)] were the independent predictors of the occurrence of chikungunya in households.

In this response, we seek to analyse and rebut the observations of Karpagam S using an understanding of the Kerala Health system and the general purpose of the Kerala Public Health Act (KPHA). The KPHA was crafted with a greater focus on a one-health and preventive approach. It does not seek to interfere in an individual's preferred choice of treatment, except in the case of public health emergencies. KPHA is not a standalone document, but a supporting tool to the existing Kerala Health Policy and various other health policies and programmes instrumental in improving the health and quality of life of the people of the State. The KPHA is intended to be an enforcement tool for legal provisions to ensure welfare maximisation of the society at large, and thus detailed discussions regarding actions to be taken beyond these legal provisions do not fall within the purview of the Act.

Introduction: Disease transmission patterns of COVID-19 have shown that masking, social distancing, contact tracing and quarantine measures are important strategies for reducing transmission. The effective implementation of quarantine is determined by the commitment of the people and monitoring by the State. The aim of the study was to find out the effectiveness of home quarantine practises and its role in determining SARS CoV2 transmission., Methods: Record-based retrospective cohort study was conducted among expatriates of Kerala who were on quarantine at their homes and later tested positive for SARS -CoV-2. Quarantine practises were categorised as strict room quarantine, incomplete room quarantine, home quarantine and no quarantine. Risk of transmission was assessed using risk ratios. Multiple logistic regression analysis was performed to find out the determinants of SARS CoV2 transmission., Results: The median (IQR) age and duration of quarantine of 95 study participants were found to be 35 (29, 44) years and 7 (3,13) days, respectively. Majority of the participants practised strict room quarantine (57%), whereas 11.6%, 16.8% and 14.7% practiced incomplete room, home and no quarantine, respectively. Home quarantine without room quarantine had 24 times odds for transmitting disease [OR (95%CI)): 24.14 (4.87--119.75), P < 0.001] and not being in quarantine for any duration before being diagnosed was found to be 14 times riskier when compared with strict room quarantine [OR (95%CI)): 14.44 (2.42-86.17), P = 0.003]., Discussion: Low-resource settings successful in the initial phases of COVID-19 pandemic should make periodic revisions in the quarantine guidelines while continually promoting physical distancing strategies., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Journal of Family Medicine and Primary Care.)

Introduction: Acute disseminated encephalomyelitis (ADEM), an immune mediated inflammatory disease is common in children. The profile and immediate outcome of children hospitalized with ADEM is scarce in the available literature., Objectives: We aimed to study the clinical profile of children with ADEM and to look for prognostic factors for outcome at discharge from hospital METHODS: We chose a retrospective cohort study of all children diagnosed with ADEM at our institution between January 2006 and December 2015, and they were evaluated, after excluding other diagnoses when they were summoned for a follow up visit. The major outcome variables were the modified Rankin Scale (mRS), the Kurtzke Expanded Disability Status Scale (EDSS) and the Glasgow outcome score (GOS) RESULTS: There were 102 children (with a mean follow up of 4.81 ± 2.78 years) and mean age at presentation, 6.16 ± 3.1 years. Pyramidal signs, ataxia, fever at onset, brain stem signs, seizures, myelitis and headache were the commoner clinical manifestations. Movement disorders particularly disabling tremor was seen in 12%. Only 52% had MRI lesions confined to supratentorial region, with 20% having thalamic lesions, 14% with corpus callosal lesions and 28% with brain stem hyperintensities. Three patients expired during the acute stage of the disease, the rest recovering with a mean mRS score of 1.92 ± 1.7 and EDSS score of 2.96 ± 3.05. On multivariable regression analysis, using mRS, presence of fever at admission, myelopathy with a definite sensory level and ventilator associated pneumonia were associated with a bad outcome. Using EDSS score (multivariable regression), presence of myelopathy with a definite sensory level and coma were associated with a bad outcome. Using GOS score (multivariable regression), presence of myelitis with a definite sensory level, signs of meningeal irritation and encephalomyeloradiculoneuropathy type of ADEM were associated with a bad outcome and headache with a good prognosis. The mean of the number of hours of altered sensorium and the mean duration of hospital stay in days had a significant association using the mRS, EDSS score and GOS., Conclusion: This study shows a profile of ADEM in South Indian children at admission and at discharge from hospital. ADEM has a good immediate outcome though death during the nadir of disease has been recorded in this study and in the literature and effort should be taken for optimal life support for these children who would have a good outcome if life support is successful. We have been able to show that, presence of myelopathy, the mean number of hours of altered sensorium and the mean duration of hospital stay were associated with a bad prognosis using three different outcome scales. Fever at admission, ventilator associated pneumonia, more profound altered sensorium at nadir of disease, signs of meningeal irritation at presentation and lower motor neuron involvement also, during the course of disease were associated with an immediate bad outcome using one of the outcome scores used in our study. Future studies should also address the question of why children with myelopathy, signs of lower motor involvement and fever at onset have a bad immediate outcome., (Copyright © 2017 Elsevier B.V.

Introduction: Cerebral palsy (CP) refers to a spectrum of disorders causing physical and intellectual morbidity. Macro and micro nutrient deficiencies often contribute to the subnormal physical and mental capabilities of them., Objectives: To assess the growth, nutritional status, physical and functional ability and quality of life in cerebral palsy children and to determine any relation with their gross motor and functional capabilities., Method: The study was conducted at a Tertiary Care Centre, with the participants in the age group 1-16 years. A pretested evaluation tool was prepared which included Anthropometric measurements, tests for hemoglobin and Vitamin D estimation, evidence of micronutrient deficiencies, Dietary patterns, Epidemiological factors, Functional assessment using GMFM (Gross Motor Function Measure ) and FIM (Functional Independent Measurement) scales and Quality of life (QOL) assessment. The data was statistically analyzed., Results: Out of the 41 children, 30 had quadriplegia, 3 had hemiplegia and 8 had spastic diplegia. 34 (82.9%) were severely underweight, 35 (85.4%) had severe stunting and 38 (92.7%) had severe wasting. Micronutrient deficiencies were noted like vitamin B complex deficiency in 37 (90.2%), vitamin A deficiency in 31 (75.6%), low vitamin D levels in 27 (65.9%) and insufficient levels in 9 (22%), severe anemia in 5 (12.2%) and moderate anemia in 26 (63.4%). The gross motor and functional scores were suboptimum in the majority of patients and the care givers had significant impairment in the quality of life., Conclusion: Majority of children with cerebral palsy had multiple nutritional deficiencies, gross motor and functional disabilities. QOL of the children and their care givers were suboptimum. A comprehensive package that address dietary intake, correction of micronutrient deficiencies especially anemia and vitamin D deficiency, physical and emotional support is recommended for the wellbeing of the affected children., Competing Interests: There are no conflicts of interest.

Introduction: Varying prevalence rates of type 2 diabetes have been observed in different parts of the southern state of Kerala, India which is in an advanced stage of epidemiologic transition. Social patterning is evident in diabetes and therefore it was decided to undertake a study on estimating the prevalence of diabetes and associated social determinants., Methodology: The adopted local self administration unit of the Medical College which is also the field practice area with a population of 25,096 was taken for the study. All the households in the area were visited and the details regarding self reported diabetes was collected after obtaining informed consent and analysis done by multivariate logistic regression., Result: The prevalence of self reported diabetes in this coastal area was found to be low at 7.4%. Type 2 diabetes was also found to occur significantly earlier among the respondents belonging to the below poverty line. Age above 40 years (OR 2 95% CI 1.5-2.7, p=.000), marital status (OR 1.9 95% CI 1.1-2.1, p=.006) presence of comorbidities (OR 635 95% CI 389-969, p=.000), more than 8 years of schooling (OR 0.64 95% CI 0.46-0.86, p=.004), living conditions as represented by presence of household source of drinking water(OR 1.4 95% CI 1.01-1.5) were found to be independent predictors. Though there was increasing trend of diabetes among the forward caste line families after backward logistic regression this disappeared leaving behind the proxy of socioeconomic status, household source of drinking water., Conclusion: Though, the state of Kerala is in an advanced stage of epidemiologic transition, coastal areas are still in the earlier phases of transition with low prevalence of type 2 diabetes mellitus. Higher education and better living conditions are important social determinants of diabetes though further studies are necessary to delineate the impact of economic status and education.

Context: Gender differences in the risk of developing non-communicable diseases (NCD) are a matter of debate. The susceptibility of a woman to NCD should be evaluated taking into consideration the social factors that limit the physical activity among women. It will be interesting to note what will happen if women are allowed to take part in physical exercise to the extent of men., Aims: To find out the gender difference in the pattern of the clinical and biochemical indices related to NCD in young adults with comparable daily physical activity., Settings and Design: This is an institution-based cross-sectional study and the setting was Lekshmibhai National College for Physical Education (LNCPE), Thiruvananthapuram, Kerala, India., Materials and Methods: The study participants were students who were regularly involved in more than three hours of physical exercise daily at least for the previous one year. The information on socio-demography, anthropometry, and blood pressure was recorded. Blood samples were taken for laboratory examination., Results: Out of 150 students registered, 126 (84%) in the age group of 17 to 25 years who fulfilled the eligibility criteria were studied. Fifty-five (43.7%) of them were women. Systolic blood pressure, fasting blood sugar, and low-density lipoprotein were found significantly lower in women. No significant difference was noted in the case of diastolic blood pressure and total cholesterol., Conclusion: Gender differences exist for NCD risk factors among young adults with comparable physical activity and physical exertion seems to be more protective for females.

Aim: To study the determinants of Tuberculosis (TB) in children between the age group of 0-14 years receiving treatment under Revised National TB Control Programme (RNTCP)., Methods: A case (registered under RNTCP) control study was undertaken with 41 cases and 82 controls., Results: Factors found to have significance according to binary logistic regression were low-birth weight (LBW) [Odd's ratio = 3.56],Malnutrition [Odd's ratio = 3.96], Passive smoking [Odd's ratio=6.28] and exposure to fire-wood smoke [Odd's ratio = 6.91]., Conclusion: LBW, malnutrition, passive smoking and fire-wood smoke are the risk factors to be addressed to prevent pediatric TB.

Context: Human Immunodeficiency Virus (HIV) infection progresses in almost all infected persons to Acquired Immunodeficiency Syndrome (AIDS). The aim of the study was to find out the determinants of rapid progression of immunodeficiency among people infected with HIV in Thiruvananthapuram district of Kerala, India., Settings and Design: The study design used was case control. The setting of the study was antiretroviral treatment (ART) centre of Government Medical College and the self-help group of HIV patients located at Thiruvananthapuram, Kerala., Materials and Methods: Cases were people having any one or more of the AIDS defining clinical conditions within 3 years from the diagnosis of HIV infection. Controls were people diagnosed as having HIV at least 3 years ago and with no AIDS-defining clinical conditions till the date of the study. Sample size was 149 with a control case ratio of 1.5:1., Statistical Analysis Used: Mean (standard deviation) and proportions were used to describe the data. Chi-square test and t test were done to test the hypotheses. Binary logistic technique was used to find out the predictors of the outcome., Results: A regression (Binary Logistic) model was used to predict the progression. Fungal infection of nail [adjusted Odds Ratio (OR), 6.4 (1.4, 28.9)] and oral candidiasis [adjusted OR, 2.6 (1.1, 6.4)] were the clinical conditions significantly associated with rapid progression. The significant social factors included non-exposure to professional counseling [adjusted OR, 7.1 (2.0, 24.5)] and the feeling of being stigmatized - felt as preoccupation with thoughts that they are gossiped about and the increase in visitors to "check them out" [adjusted OR, 26.1 (4.9, 138.4)]. The protective nutritional factors in the model were frequent consumption of legumes [adjusted OR, 0.12 (0.04, 0.36)], eggs [adjusted OR, 0.29 (0.09, 0.93)], and plenty of oral fluids [adjusted OR, 0.18 (0.07, 0.47)]., Conclusions: An approach incorporating the clinical, social, and nutritional factors may retard the progression of HIV infection.

Background: Two epidemics of chikungunya fever were reported from Kerala in 2006 and 2007. We aimed to investigate the environmental factors of households affected by chikungunya fever and to estimate the proportion of population that suffered from the disease during the epidemic in 2007., Methods: A cross-sectional survey was conducted in the 5 heavily affected districts of Kerala during October-November 2007. The 2-stage sampling technique was used to collect data from 10 clusters, each having 18 houses from every district, by interviewing the subjects using a structured questionnaire. The sample size was 900., Results: The proportion of the population affected by chikungunya fever was 57.1% (95% CI: 52.8%-61.4%). There was a significant association between location of houses and disease status. Houses located near a public conveyance facility (within 250 m) were relatively protected from the disease (OR 0.19 [0.06-0.60]). About 69% of the households perceived mosquito infestation as a problem and 46.6% used fumes to avoid mosquitoes. More than 42% of households were not using any anti-mosquito measures at the time of the survey. Stored drinking water was the most common potential breeding source in the houses (23.5%). Households which did not store water inside were protected from the disease (OR 0.22 [0.08-0.65])., Conclusion: The study indicated the persistence of favourable domestic and environmental factors after the epidemic, reflecting the necessity to strengthen anti-mosquito campaigns.
