Neighborhood Walkability Index and Its Association With Indices of Childhood Obesity in Bengaluru, Karnataka

Background: The prevalence of childhood obesity is increasing in low-middle income countries like India. Built environment features such as walkability can influence weight-related outcomes but data from developing countries are scanty. Objective: To develop population level walkability index in urban Bengaluru, and examine its association with indices of childhood obesity in school children. Study Design: Nested cross-sectional study based on a cohort. Participants: Normal healthy children aged 6 to 15 years from urban schools in Bengaluru. The children were stratified into different land use classification such as residential, commercial and open space based on residential address. Methods: Anthropometric data, body composition data, measured using air displacement plethysmography. Outcomes: Walkability index derived using residential density, street connectivity and land-use mix environment variables. Results: The mean (SD) of age, body mass index (BMI), BMI zscore and percentage body fat (% Body fat) of 292 (50% boys) children were 10.8 (2.9) year, 17.4 (3.3) kg/m2, -0.27 (1.35) and 20.9% (8.8), respectively. The mean (SD) walkability index was 16.5, which was negatively associated with BMI (slope -0.25 and -0.08) and percentage body fat (slope -0.47 and -0.21) for age 5 and 10 years, respectively in children, but the effects decreased with increasing age. Conclusions: The findings of this pilot study suggest that the neighborhood walkability may be associated with the obesity indices in younger children. Future longitudinal studies are needed to understand how built environment affects health and body composition of children in India and other low-middle income countries.

Incidental isolated renal mucormycosis in immunocompetent patient: a rare and atypical presentation

Mucormycosis is a group of clinical syndromes resulting from infection by one of a group of related filamentous fungi. It is an opportunistic fungal infection that rarely occurs in immunocompetent individual. Isolated involvement of any organ is rare and only a few cases of renal mucormycosis have been reported. We present a case report of atypical presentation of a case of renal mucormycosis in a healthy adult with no predisposing factors. A 48 year non diabetic immunocompetent patient underwent right nephrectomy for painful non-functioning kidney. Biopsy showed chronic pyelonephritis with broad non-septate hyphae suggestive of mucormycosis. Post op followup of patient is normal. Mucormycosis of kidney causes extensive infarction and necrosis due to direct angioinvasion and vascular thrombosis leading to fulminant acute renal failure. The disease mimics pyogenic infection leading to delay in diagnosis and hence resulting in high mortality. High index of suspicion is needed for early diagnosis. Urine and blood cultures are usually sterile. Characteristic CT findings include diffuse enlargement of the kidney with absence of contrast excretion and multiple low-density areas in the renal parenchyma representing fungal abscess. Whenever suspected, FNAC or biopsy is strongly advocated as no imaging can confirm the diagnosis. Nephrectomy or debridement of necrotic tissue along with IV Amphotericin B consist the principal treatment. Renal mucormycosis presenting an indolent course and found incidentally after nephrectomy is extremely rare. In an incidentally found mucormycosis, the role of further investigations to find the source and the role of antifungals have to be further studied.

A cross sectional study on knowledge, attitude and practice of family planning method usage among urban women of Dr. B. R. Ambedkar Medical College field practice area

Background: India is currently facing “population explosion” which is directly perpetuating development of country. Family planning is the only safest and cost-effective strategies to have impact on health of women.Methods: Community based cross sectional study, conducted by face to face interview with women included for study after systematic random sampling. The collected information was analysed using appropriate statistical tools.Results: Total of 88.7% of women were aware that family planning is for limitation of births but, 292 (70.2%) women had ever used contraceptive, and 30 (24.2%) of them have faced minor complications, which has either self-resolved or on medication. The most common reason for not using contraceptive was being uncomfortable (76.6%) to use them.Conclusions: Women had good knowledge regarding contraceptives, but most of the women followed methods suggested by their elders. Advertisement regarding newer methods has to be strengthened.

In vitro hypoglycemic potential of spices: Cinnamon and Cumi

Present study evaluates the anti-hyperglycemic potential of two Indian spices Cinnamomum zeylanicum [CZ] and Cumin cyminum [CC] [whole powder and aqueous extracts] using in vitro techniques like glucose adsorption assay, amylolysis kinetics and ex vivo assays like amylase, Sucrase and ?-glucosidase assay. CZ displayed higher glucose adsorption and glucose diffusion retardation than CC, as shown by glucose adsorption and amylolysis kinetics assay. CZ showed lower inhibition of alpha-amylase and sucrase where as CC has no effect on both the enzymes. In case of alpha glucosidase, CC had better inhibition than CZ. Further research is needed to understand the mechanism through which both the spices act to regulate the hyperglycemia

Rapid culture-based detection of living mycobacteria using microchannel electrical impedance spectroscopy (m-EIS)

BACKGROUND: Multiple techniques exist for detecting Mycobacteria, each having its own advantages and drawbacks. Among them, automated culture-based systems like the BACTEC-MGIT™ are popular because they are inexpensive, reliable and highly accurate. However, they have a relatively long "time-to-detection" (TTD). Hence, a method that retains the reliability and low-cost of the MGIT system, while reducing TTD would be highly desirable. METHODS: Living bacterial cells possess a membrane potential, on account of which they store charge when subjected to an AC-field. This charge storage (bulk capacitance) can be estimated using impedance measurements at multiple frequencies. An increase in the number of living cells during culture is reflected in an increase in bulk capacitance, and this forms the basis of our detection. M. bovis BCG and M. smegmatis suspensions with differing initial loads are cultured in MGIT media supplemented with OADC and Middlebrook 7H9 media respectively, electrical "scans" taken at regular intervals and the bulk capacitance estimated from the scans. Bulk capacitance estimates at later time-points are statistically compared to the suspension's baseline value. A statistically significant increase is assumed to indicate the presence of proliferating mycobacteria. RESULTS: Our TTDs were 60 and 36 h for M. bovis BCG and 20 and 9 h for M. smegmatis with initial loads of 1000 CFU/ml and 100,000 CFU/ml respectively. The corresponding TTDs for the commercial BACTEC MGIT 960 system were 131 and 84.6 h for M. bovis BCG and 41.7 and 12 h for M smegmatis, respectively. CONCLUSION: Our culture-based detection method using multi-frequency impedance measurements is capable of detecting mycobacteria faster than current commercial systems.

Antibacterial potential of fungal endophytes isolated from Boerhaavia diffusa L.

Boerhaavia diffusa L. is widely used for its ethno-medicinal properties. The present study assessed the antibacterial activity of endophytic fungi harbored in this plant. The endophytic fungi isolated belonged to various genera like Aspergillus, Cladosporium, Colletotrichum, Curvularia, Fusarium, Pestalotiopsis and Zygorhynchus and the overall colonization frequency of endophytic fungi was found to be 24%. Among the isolated fungi Aspergillus fumigatus, Cladosporium sphaerospermum, Fusarium sp. and Zygorhynchus sp. showed antibacterial activity in preliminary screening against one or all the test bacteria. Further, after fermentation, the ethyl acetate extracts of the selected endophytic fungi displayed variable antibacterial activity with maximum 54.75 mm and a minimum 27.50 mm zone of inhibition against test bacteria in disc diffusion assay. The lowest minimum inhibitory concentration (MIC) was 0.156 mg ml-1 in the broth dilution assay against a B. subtilis, S. typhi and S. aureus, while it was 0.312 mg ml-1 against E. coli which was offered by the ethyl acetate extracts of A. fumigatus.

Assessment of validity and reliability of Hindi version of geriatric oral health assessment index (GOHAI) in Indian population.

Objective: The objective of this study was to translate the Geriatric Oral Health Assessment Index (GOHAI) into the Hindi language and assess its validity and reliability for use among people in India. Materials and Methods: GOHAI was translated into the Hindi language and self-administered to 420 subjects aged 55 years or above. The measures for reliability, and concurrent, convergent, and discriminant validity were assessed. The questionnaire sought information about sociodemographic details, habits related to tobacco, dental visits, tooth brushing, and self-reported perceptions of general and oral health. Results: Cronbach's alpha (0.774) showed high internal consistency and homogeneity between items. Low GOHAI scores were associated with the perceptions of poor oral and general health, low satisfaction with oral health, and a perceived need for dental care. Respondents with high socioeconomic status were likely to have high GOHAI scores. Conclusion: The Hindi version of the GOHAI demonstrated acceptable validity and reliability, and will be an important instrument to measure oral health-related quality of life (OHRQoL) for people in this region.

Analysis of cranio-cerebral injuries by blunt force.

Despite current advances in public education and in automobile safety requirements, cranio-cerebral injuries continues to be a major cause of morbidity and mortality and accounts for significant portion of health care costs today. Trauma respects neither geography nor body systems. Consequently head injury occurs every 15 seconds and a patient dies from a head injury every 12 minutes, a day doesn’t pass that an emergency department physician is not confronted with a head injured patient. The present work is based on the observation and study made on 117 cases collected. These cases include 39 cases who died before being admitted to any hospital and were sent directly by the police to postmortem, Mysore Medical College, Mysore, and 78 cases that died in the hospital under medical care. Clinical data are available for 78 cases that died in the hospital after undergoing some treatment. An attempt is made in these cases to correlate clinical findings with the autopsy findings.

Clinical presentation and outcome in hospitalized patients of 2009 pandemic influenza A [H1N1] viral infection in Oman

In 2009, cases of human infection with a novel influenza A [H1N1] virus were detected and soon reached a pandemic level. Presenting clinical features of this disease in Oman were observed and an attempt was made to identify features predicting the high risk of mortality. The clinical and laboratory features at the time of presentation in adult patients admitted with flu-like illness or pneumonia were studied who were later diagnosed as H1N1 infection by PCR of nasopharyngeal and/or throat swabs. H1N1 infection mostly affected younger individuals who presented with fever and cough. One-third of the patients had rhinorrhea and a few had vomiting and diarrhea. Chest crepitations were common. Most of the patients had normal or low cell counts. The chest X-ray was normal in 23 [41.8%] cases, while in other cases pneumonia was detected characteristically starting from base and extending up. Almost half of the patients were either in frank or impending respiratory failure. Nine [16.4%] patients died. It is difficult to identify H1N1 influenza cases from other patients with a flu-like illness, but it can be strongly suspected when a patient presents with basal pneumonia, particularly if bilateral, with lymphocytopenia, and is hypoxemic, in the presence of other H1N1 infected cases in the community. These features are also indicative of severe illness with high mortality risk
