An assessment of "Organization Culture" in District Program Management Units established under National Health Mission in a western state of India.

Background: State programme management unit and District Programme Management Units (DPMU) are established under National Health Mission with an expectation to strengthen the management structures at the state and district levels, respectively. This is a major initiative to bring change in organisation structure and an effort to embrace change in working culture. The study was undertaken in a western Indian state to assess and compare the organisation culture in DPMUs. Methods: Districts of the state were divided into three strata based on the geographical and demographic features. One district from each stratum was randomly selected for the study. In-depth interview of nine key officials in each sampled DPMU was conducted with the use of standardised questionnaire-openness, confrontation, trust, authenticity, proactiveness, autonomy, collaboration and experimentation (OCTAPACE), developed by Pareek. Results: Values of OCTAPACE were diversely distributed with significant difference in distribution of scores between these domains (p < 0.05). Pro-action and Trust scores were relatively higher and consistent in the study units. Values of experimentation were lower and inconsistent. There was no significant difference in the distribution of scores between three sampled DPMUs for openness, confrontation, trust, authenticity, pro-action, autonomy and experimentation (p > 0.05). However, the distribution of collaboration score was significantly less in DPMU of desert district in comparison to DPMU of plain and tribal district (p < 0.05). Conclusion: The lacuna in values of organisation culture should be addressed to strengthen the existing management structures at the state and district levels.

Lyme Borreliosis, a public health concern in India: Findings of Borrelia burgdorferi serosurvey from two states.

Background: Lyme borreliosis is a public health concern in India. The prevalence of the disease is still undetermined with major entomological and epidemiological gaps. The present study was conducted to determine the seropositivity of Borrelia burgdorferi in Sikkim and Arunachal Pradesh, India. Methods: A cross-sectional serosurvey was conducted in Sikkim and Arunachal Pradesh. Data collection tools were developed and standardized for the collection of clinico-socio-demographic data. Sample size for each site was calculated using the formula for the estimation of a single proportion. Qualitative detection of IgG antibodies in serum samples was done using NovaLisa™ Lyme Borrelia IgG ELISA kit. Results: A total of 793 participants were enrolled, 484 (61%) from Arunachal Pradesh and 309 (39%) from Sikkim. Out of 793 participants, 21 (2.7%), 22 (2.8%), 6 (0.8%), 29 (3.7%), 44 (5.5%), and 16 (2.1%) gave history of tick bite, rash, erythema migrans, migratory muscle pain, migratory joint pain, and numbness, respectively, in the past one year. The adjusted seroprevalence (for sensitivity and specificity of kit) for the study is 3.7 (2.4-5.2). No signs or symptoms were found to be associated with IgG ELISA positivity. The state-wise distribution of seropositivity for Arunachal Pradesh and Sikkim was 4.1 (95% CI: 2.5-6.3) and 2.3 (95% CI: 0.9-4.6), respectively. Conclusion: This study establishes the state of Sikkim as a new endemic area in India of Lyme disease besides its already reported endemicity in Arunachal Pradesh. No association was conclusively established between symptoms of Lyme and IgG seropositivity emphasizing the need for detailed history taking and clinical suspicion in endemic areas.

Food poisoning outbreak in a religious mass gathering.

BACKGROUND: Food poisoning outbreaks are commonly seen in mass social events where food is prepared under temporary arrangements. This study reports a food poisoning outbreak in a city of western Maharashtra, India, where around 4000 people had consumed food during a religious community lunch and reported sick to the nearby hospital with complaints of diarrhea, abdominal cramps, fever with chills, and vomiting. METHODS: This was a retrospective-prospective study. Investigation of the food poisoning outbreak was conducted to identify the causes and recommend preventive measures. Interview method was used to elicit food history from the affected and non-affected persons. Inspection of the cooking area was conducted to find the likely source of contamination. RESULTS: A total of 291 patients reported sick after consumption of meal at a religious mass gathering. The range of incubation period was from 10 hours to 40 hours. Predominant features were diarrhea (100%), abdominal cramps (89%), fever with chills (81%), and vomiting (28.5%). Maximum relative risk of 14.89 was seen for green gram (moong dal) with 95% confidence interval of 2.16-102.6. Keeping the incubation period and clinical profile in view, the likely organisms are enteropathogenic Escherichia coli or Salmonella spp. CONCLUSION: Maintaining food safety during mass gatherings is a major challenge for public health authorities. The Food Safety and Standards Act (2006) in India brings the food consumed during religious gatherings such as 'prasad' and 'langar' under its purview and comprehensively addresses this issue.

E2 Ubiquitin-conjugating Enzyme, UBE2C Gene, Is Reciprocally Regulated by Wild-type and Gain-of-Function Mutant p53.

Spindle assembly checkpoint governs proper chromosomal segregation during mitosis to ensure genomic stability. At the cellular level, this event is tightly regulated by UBE2C, an E2 ubiquitin-conjugating enzyme that donates ubiquitin to the anaphase-promoting complex/cyclosome. This, in turn, facilitates anaphase-onset by ubiquitin-mediated degradation of mitotic substrates. UBE2C is an important marker of chromosomal instability and has been associated with malignant growth. However, the mechanism of its regulation is largely unexplored. In this study, we report that UBE2C is transcriptionally activated by the gain-of-function (GOF) mutant p53, although it is transcriptionally repressed by wild-type p53. We showed that wild-type p53-mediated inhibition of UBE2C is p21-E2F4-dependent and GOF mutant p53-mediated transactivation of UBE2C is NF-Y-dependent. We further explored that DNA damage-induced wild-type p53 leads to spindle assembly checkpoint arrest by repressing UBE2C, whereas mutant p53 causes premature anaphase exit by increasing UBE2C expression in the presence of 5-fluorouracil. Identification of UBE2C as a target of wild-type and GOF mutant p53 further highlights the contribution of p53 in regulation of spindle assembly checkpoint.

Are vitamin D, B12, and folate deficiency associated with depressive disorder? A case-control study.

Background: Depression is a global burden with complex etiopathogenesis. Some nutrients including vitamin D, B12, and folate deficiency have been considered risk factors for depression. Therefore, this study has been contemplated to find out the possible association of vitamin D, B12, and folate deficiency with depression. Method: This study included 81 case subjects with depression and 95 control subjects without any International Classification of Diseases (ICD)-10 diagnosis. The sociodemographic details were collected from each subject. Beck's Depression Inventory (BDI) was administered to identify the severity of depression. The blood samples were collected and measured for vitamin D, B12, and folate along with other laboratory investigations as per exclusion criteria. The data were obtained and analyzed using descriptive and inferential statistics. Results: The mean age ± standard deviation (SD) of the case and control subjects were 34.86 ± 9.25 and 33.49 ± 8.44, respectively, without any significant difference (P > 0.05). The subjects with vitamin D deficiency were found to have four times higher odds (OR 4.703; 95% CI = 2.378-9.300) for depression compared to subjects with sufficient vitamin D levels. In addition, there was a negative correlation between vitamin D levels and the severity of depression as per BDI scoring (r = -.384, P < 0.01). However, there was no significant association identified between the case and control group with respect to serum vitamin B12 and folate levels. Conclusion: The results of the study revealed that vitamin D deficiency has an association with depression. However, further research studies are needed to validate its correlation to the etiopathogenesis of depression.

Polymorphisms at p53, p73, and MDM2 loci modulate the risk of tobacco associated leukoplakia and oral cancer.

Polymorphisms at loci controlling cellular processes such as cell cycle, DNA repair, and apoptosis may modulate the risk of cancer. We examined the association of two linked polymorphisms (G4C14-A4T14) at p73 and one polymorphism (309G > T) at MDM2 promoter with the risk of leukoplakia and oral cancer. The p73 and MDM2 genotypes were determined in 197 leukoplakia patients, 310 oral cancer patients and in 348 healthy control subjects. The p73 GC/AT genotype increased the risk of leukoplakia (OR = 1.6, 95% CI = 1.1-2.3) and oral cancer (OR = 2.4, 95% CI = 1.7-3.3) but the 309G > T MDM2 polymorphism independently could not modify the risk of any of the diseases. Stratification of the study population into subgroups with different tobacco habits showed that the risk of the oral cancer is not modified further for the individuals carrying p73 risk genotype. However, leukoplakia patients with smokeless tobacco habit showed increased risk with combined GC/AT and AT/AT (OR = 3.0, 95% CI = 1.3-7.0) genotypes. A combined analysis was done with our previous published data on p53 codon 72 pro/arg polymorphism. Analysis of pair wise genotype combinations revealed increase in risk for specific p73-MDM2 and p73-p53 genotype combinations. Finally, the combined three loci analyses revealed that the presence of at least one risk allele at all three loci increases the risk of both leukoplakia and oral cancer.

Ecotoxicological assessment of pesticides and their combination on rhizospheric microbial community structure and function of Vigna radiata.

India is one of the leading countries in production and indiscriminate consumption of pesticides. Owing to their xenobiotic nature, pesticides affect soil microorganisms that serve as mediators in plant growth promotion. Our study aimed to deliver a comprehensive picture, by comparing the effects of synthetic pesticides (chlorpyriphos, cypermethrin, and a combination of both) with a biopesticide (azadirachtin) at their recommended field application level (L), and three times the recommended dosage (H) on structure and function of microbial community in rhizosphere of Vigna radiata. Effect on culturable fraction was assessed by enumeration on selective media, while PCR-denaturing gradient gel electrophoresis (DGGE) was employed to capture total bacterial community diversity. This was followed by a metabolic sketch using community-level physiological profiling (CLPP), to obtain a broader picture of the non-target effects on rhizospheric microbial community. Although plant parameters were not significantly affected by pesticide application, the microbial community structure experienced an undesirable impact as compared to control devoid of pesticide treatment. Examination of DGGE banding patterns through cluster analysis revealed that microbial community structure of pesticide-treated soils had only 70% resemblance to control rhizospheric soil even at 45 days post application. Drastic changes in the metabolic profiles of pesticide-treated soils were also detected in terms of substrate utilization, rhizospheric diversity, and evenness. It is noteworthy that the effects exacerbated by biopesticide were comparable to that of synthetic pesticides, thus emphasizing the significance of ecotoxicological assessments before tagging biopesticides as "safe alternatives."

Polio Eradication in India: Myth or Reality.

BACKGROUND: Poliomyelitis has been eradicated from large parts of the world. In South East Asian Region, India and Pakistan remain the only countries where active transmission of the disease persists. A decade-long initiative to eradicate the disease is in progress in India. Initial results were encouraging, with the number of fresh polio decreasing till 2001. The year 2002, however, witnessed a setback, with significant rise in cases of poliomyelitis. METHODS AND RESULTS: The eradication measures have been reviewed. The corrective measures appear to be succeeding. Various facets of eradication and their impact are evaluated. CONCLUSION: Poliomyelitis is controlled but the ultimate target of eradication may still be elusive, keeping in mind operational lacunae and vaccine virus characteristics.
