ABSTRACT
Background & objectives: An. annularis van der Wulp (1884) is the secondary malaria vector of importance in India. In Jharkhand state it is present in almost all the districts abundantly and transmits malaria. The development of resistance to Dichlorodiphenyltrichloroethane (DDT) in An. annularis was reported from various parts of India. The main objective of this study was to generate information on insecticide susceptibility status of An. annularis to DDT, malathion, deltamethrin and permethrin in different districts of Jharkhand state. Methods: Adult An. annularis female mosquitoes were collected form villages of six tribal districts Simdega (Kurdeg and Simdega CHC), Khunti (Murhu and Khunti CHCs), Gumla (Bharno and Gumla CHCs), West Singhbhum (Chaibasa and Bada Jamda CHCs), Godda (Poraiyahat and Sunderpahari (CHCs) and Sahibganj (Borio and Rajmahal CHCs). Insecticide susceptibility status was determined by using WHO tube test method against prescribed discriminatory dosages of insecticides, DDT - 4.0%, malathion - 5.0%, deltamethrin - 0.05% and permethrin - 0.75%. Results: An. annularis was reported resistant to DDT in six districts, possible resistant to malathion in districts Gumla, Khuntiand Sahibganj and susceptible to deltamehrin (98% to100% mortality) and permethrin (100% mortality). Interpretation & conclusion: An. annularis, the secondary vector species is associated with the transmission of malaria reported resistant to DDT and susceptible to pyrerthroids deltamethrin and permethrin. In view of large-scale distribution of long-lasting insecticidal nets (LLINs) in all the districts, the response to synthetic pyrethroid needs to be periodically monitored to assess the effectiveness.
ABSTRACT
Lymphatic filariasis (LF) is a vector-borne neglected tropical disease, causing permanent disability. The disease is debilitating and widespread, leading to tremendous productivity and economic loss. The Government of India (GOI) prioritized the elimination of LF through the annual mass drug administration (MDA) programme in 2004 and continued with a single dose of diethylcarbamazine citrate (DEC), 6 mg/kg of body weight, plus albendazole annually over a period of 5-6 years. The GOI had set the target to achieve LF elimination by 2015 and now by 2030. The progress so far has been suboptimal. Much remains to be done as about 84 per cent of the total 328 endemic districts are still under MDA. The major challenge in implementing MDA is poor compliance. It is necessary to have a feasible alternative strategy addressing the above challenge to achieve the desired goal of LF elimination. At this juncture, a well-researched approach, i.e. the use of DEC-fortified salt, also advocated by the World Health Organization, as a unique form of MDA, is proposed. As per this strategy, a low dose of DEC (0.2% w/w) is added to the cooking salt at the manufacturing facility of iodized salt and consumed by the LF-endemic communities for about two years. Many examples of successful use of this strategy for LF elimination in small- and large-scale trials have been documented in India and several other endemic countries in the world. Implementing DEC–iodine-fortified salt is a safe, less expensive, more efficient and prompt approach for achieving the elimination of LF in India. Adverse effects are none or minor and self-limiting. The DEC-fortified salt strategy can easily piggyback on the existing countrywide deployment of iodized salt under the National Iodine Deficiency Disorders Control Programme (NIDDCP), which has achieved a great success in reducing iodine-deficiency disorders such as hypothyroidism. This existing robust programme can be leveraged to launch DEC-fortified salt for the community. If implemented appropriately, this strategy will ensure the complete cessation of LF transmission within two years from its introduction. If the said strategy is implemented in 2022, it is expected that India will be able to achieve the LF elimination by 2024, much before the global target of 2030.
ABSTRACT
Background & objectives: Scrub typhus caused by Orientia tsutsugamushi presents as acute undifferentiated fever and can be confused with other infectious causes of fever. We studied scrub typhus as part of a study on hospital-based surveillance of zoonotic and vector-borne zoonotic diseases at a tertiary care hospital located in the Wardha district, Maharashtra, India. We report here descriptive epidemiology and climatic factors affecting scrub typhus. Methods: Patients of any age and sex with fever of ?5 days were enrolled for this study. Data on sociodemographic variables were collected by personal interviews. Blood samples were tested by IgM ELISA to diagnose scrub typhus. Confirmation of scrub typhus was done by indirect immunofluorescence assay for IgM (IgM IFA). The climatic determinants were determined using time-series Poisson regression analysis. Results: It was found that 15.9 per cent of the study participants were positive for scrub typhus by IgM ELISA and IgM IFA, both. Positivity was maximum (23.0%) in 41-60 yr of age and more females were affected than males (16.6 vs. 15.5%). Farmworkers were affected more (23.6%) than non-farm workers (12.9%). The disease positivity was found to be high in monsoon and post-monsoon seasons (22.9 and 19.4%) than in summer and winter. Interpretation & conclusions: There were three hot spots of scrub typhus in urban areas of Wardha district. Rainfall and relative humidity in the previous month were the significant determinants of the disease
ABSTRACT
Background & objectives: Microscopy is considered as the gold standard for malaria diagnosis, however sub-microscopic infections can only be detected by Polymerase chain reaction, which demands high cost and elaborate laboratory setup. The Micro-chip PCR based Truenat Malaria Pv-Pf and Pf assay is a portable solution for detection of sub-microscopic/asymptomatic cases of malaria in the field, three lots of which were evaluated for P. falciparum and P. vivax malaria. Methods: Three lots of Truenat® Malaria Pv-Pf and Pf assay (kits) were assessed using blood samples of P. vivax and P. falciparum as well as malaria negative blood samples. DNA was extracted from the blood samples using the Trueprep Auto v2 Universal Cartridge based sample prep device and real time qPCR was performed using Truelab DUO micro PCR Analyzer with three lots of Truenat® Malaria Pv-Pf and Pf Assays. Mean, Standard deviation and one-way analysis of variance (ANOVA) was used to assess the significance of inter-lot variability in Cycle threshold values. Results: The Truenat® Malaria Pv-Pf and Pf assays identified the malaria parasites with 100% accuracy. Based on the test for variance (ANOVA) the inter-lot variability in cycle threshold values were not significant, indicating a high degree of precision. Interpretation & conclusion: Based on high accuracy and precision between different lots, the Truenat® Malaria Pv-Pf and Pf assays were found to be suitable for the diagnosis of sub-microscopic infections in field conditions to provide support in elimination of malaria.
ABSTRACT
Human Development Report (HDR) 2010 in its 20 th year contains several significant changes. Indicators to measure the three dimensions of Human Development Index (HDI) have been changed: Gender-related Development Index (GDI) and Gender Empowerment Index have been replaced by Gender Inequality Index (GII) and Human Poverty Index has been replaced by Multi-dimensional Poverty Index. Inequality-adjusted HDI (IHDI) has been introduced for the first time. Between 1980 and 2010, India's HDI rose by 1.6% annually from 0.320 to 0.519. While India's HDI value has improved over time, the rank has not improved as much as compared to other developing countries. On GII, India ranked at 122 with a GII value of 0.748 (ranges between 0 and 1) in 2010 HDR (based on data of 2008), revealing considerable loss in achievements in three dimensions of human development - reproductive health, empowerment, and labor market - due to inequality between genders. Multi-dimensional Poverty Index was 0.296 (2000-2008) and IHDI was 0.365 (2000-2007).
ABSTRACT
There has been an increased influx of probiotic products in the Indian market during the last decade. However, there has been no systematic approach for evaluation of probiotics in food to ensure their safety and efficacy. An initiative was, therefore, taken by the Indian Council of Medical Research (ICMR) along with the Department of Biotechnology (DBT) to formulate guidelines for regulation of probiotic products in the country. These guidelines define a set of parameters required for a product/strain to be termed as ‘probiotic’. These include identification of the strain, in vitro screening for probiotic characteristics, animal studies to establish safety and in vivo animal and human studies to establish efficacy. The guidelines also include requirements for labeling of the probiotic products with strain specification, viable numbers at the end of shelf life, storage conditions, etc., which would be helpful to the consumers to safeguard their own interest.

Corneal transplantation remains a major treatment option for restoring sight among those suffering from corneal blindness. The number of corneal transplants done is far less than the actual requirement in India. This is largely due to the inadequate numbers of corneas collected. Medical students can be involved in the motivation of patients and relatives to pledge their eyes and to do grief counseling for donating eyes. The aim of the study was to assess the perception and willingness of 180 first-year medical students towards eye donation in Delhi. They were administered a pretested semi-structured questionnaire on eye donation. Data were analyzed using Epi-Info software package 6.04 version. The majority (99.4%) of students knew that eyes can be donated after death but only 41.1% knew that the ideal time of donation was within six hours of death. Most participants (87.2%) were willing to donate eyes. Nobility in the act of eye donation was the main motivational force for eye donation according to 85.5% of students. Perceived reasons for not pledging eyes by the people were: lack of awareness (32.7%), objection by family members (27.7%), unsuitability to donate because of health problem (17.7%) and the unacceptable idea to separate the eye from the body (15.5%). Mass media such as television, newspapers, magazines and posters were important sources of information on eye donation. Perceived reasons for not donating eyes need to be considered while creating awareness about eye donation in the community.

BACKGROUND: Despite efforts by government and other agencies, neonatal morbidity and mortality continues to be high in India. Among other reasons, newborn care practices are major contributors for such high rates. AIMS: To find out the newborn care practices including delivery practices, immediate care given after birth and breast-feeding practices in an urban slum of Delhi. SETTINGS AND DESIGN: Community based, cross-sectional survey in a resettlement colony (a type of urban slum). MATERIALS AND METHODS: Semi-structured, pre-tested schedule was used to interview 82 mothers of newborns in the study area. STATISTICAL ANALYSIS: Data was analyzed using Epi - info version 6.04. Fischer exact test and chi2 test were applied. A P value of less than 0.05 was considered significant. RESULTS AND CONCLUSION: More than half i.e. 26 (56.1%) of home deliveries, which were mostly conducted by dais (24, 91.3%) or relatives in 4 (8.7%) of home deliveries. Bathing the baby immediately after birth was commonly practiced in 38 (82.6%) of home deliveries. Finger was used to clean the air passage in most of the home deliveries (29, 63%). About 61% (28) of home delivered newborns were not weighed at birth. Rooming in was practiced in majority of the cases. A few of home delivered neonates (12) were given injection tetanus toxoid by unqualified practitioners. Use of clip, band or sterile thread to tie the cord and no application to the cord was significantly higher in institutional deliveries. Breast milk as the first feed was significantly more in institutional deliveries. There is an urgent need to reorient health care providers and to educate mothers on clean delivery practices and early neonatal care.

OBJECTIVE: To find out the magnitude of probable psychopathology in children and study association of psychopathology with demographic, developmental and social factors. METHODS: Childhood Psychopathology Measurement Schedule (CPMS) was used to measure the magnitude of probable psychopathology in 620 children from an urban slum of Miraj (Maharashtra). A second schedule recorded demographic, developmental and social factors. RESULTS: CPMS score > 10 was observed in 102 children (16.5%). It was significantly higher in children aged 7-10 years, in males, belonging to lower socioeconomic status, large families, being first born, having low birth weight (LBW); body mass index (BMI) less than 18.5. Low maternal education and alcohol abuse in father also had significant association with CPMS score > 10. CONCLUSION: Findings suggest a need to educate the community about psychological implications of LBW, large family size and overcrowding in children. Improving maternal education and controlling alcoholism could help in reducing childhood psychopathology.
