Association of Smoking with the Blood Concentration of 25-Hydroxy Vitamin D and Testosterone at High and Low Altitudes.

PURPOSE: This research examined the association of cigarette smoking and altitude with the blood levels of 25-hydroxy vitamin D, testosterone and carotid artery thickness. PATIENTS AND METHODS: This comparative cross-sectional study involved 37 non-smokers and 24 smokers from a high-altitude area (≥2245 m above sea level) and 40 smokers and 40 non-smokers from a low-altitude area (39-283 m above sea level). The blood testosterone level was determined spectrophotometrically, and the 25-hydroxy vitamin D concentration was measured by ELISA. The IMT of the right and left carotid arteries was determined using ultrasound imaging. RESULTS: Smoking notably elevated the thickness of the intima media of the right and left carotid arteries at both high and low altitudes (p ≤ 0.001). Smoking at high altitude was associated with a significant increase in the concentration of 25-hydroxy vitamin D and testosterone, while at low altitude it was associated with a significant decrease in both parameters (p ≤ 0.046). CONCLUSION: These contrasting results suggest that future studies should focus on finding out if other biochemical parameters show any significant differences in smokers or/and non-smokers when they are tested at elevated height and sea-level. This indicates that dose modifications of medicines (related to alterations in vitamin D and testosterone levels) should be kept in mind while treating smokers and non-smokers at elevated height above sea level.

An application of Indian public health standard for evaluation of primary health centers of an EAG and a Non-EAG state.

National Rural Health Mission (NRHM) has provided the opportunities to develop a standard for Sub centers, PHCs and CHCs in the country, popularly known as Indian Public Health Standards (IPHS). The study was carried out to find out and compare to what extent the IPHS were followed by the PHCs in the selected districts of both the Empowered Action Group (EAG) state of Assam and non EAG state of Karnataka. It was a Cross sectional observational study conducted during September-October 2008 where the quality of care and services provided in the selected PHCs as per the IPHS norms was assessed. All the PHCs in both the studied districts were rendering the assured services of OPD, 24hrs general emergency service and referral services while 24 hour delivery services were being provided by 80% of the PHCs of the selected districts of both the states. Functional labor rooms were available only in 80% and 90% of the studied PHCs in Assam and Karnataka respectively. Basic laboratory facilities, for routine blood, urine and stool examination were available in 80% of the studied PHCs in the non-EAG state of Karnataka while it was only in 20% of the studied PHCs of the EAG state of Assam. The findings of the present study revealed important deficiencies as per IPHS norms in the studied PHCs of both Assam and Karnataka.

Hand washing practices in two communities of two states of Eastern India: an intervention study.

BACKGROUND: Public health importance of hand washing as well as its importance in reduction of communicable diseases such as diarrhea and acute respiratory infections have been highlighted in many studies worldwide. OBJECTIVE: This study was designed to study the hand washing practices followed in two urban slums as well as to assess and compare the status of different components of hand washing at the pre- and post-intervention phases. MATERIALS AND METHODS: A community-based cross-sectional intervention study on hand washing practices was carried out at two urban slums situated in two states of Eastern India with similar sociocultural and linguistic background. The study was carried out by using an interview technique as well as observation of hand washing practices. Interpersonal communication for behavioural change was chosen as a method of intervention. RESULTS: The majority (>90%) practiced hand washing after defecation in both the study areas. However, hand washing following all six steps and for stipulated time period was seen to be poor before intervention. Significant improvement was observed in all the aspects of hand washing after intervention in both the areas. The poor practice of hand washing was observed in some situations and needed attention. Use of soap and clean material for drying hands after hand washing was poor initially followed by improvement after intervention. CONCLUSION: Based on the findings of the study, it could be suggested that Behaviour Change Communication program should be further planned with emphasis on different components of hand washing with a final objective to bring down the incidence of target diseases.
