This study was an attempt to investigate the socio-economic determinants of helmet wearing in an urban setting of India. A household survey using multistage cluster random sampling was conducted among 9014 individuals in Pune city from March 2008 to February 2009. Among 2259 individuals who reported driving two-wheeled vehicles, 1509 (66.8%) reported possession of a helmet, and among those who had reported possession of a helmet, only 700 (46.0%) reported regular use of helmets. The results of multiple logistic regression analysis showed that residence, type of family, gender and socio-economic status were significantly associated with possession of helmet, and gender, residence and family type were significantly associated with regular helmet use while possessing one. In conclusion, this study showed that helmet-wearing behaviour is mostly influenced by the neighbourhood environment and norms and family and peer influence on behaviour rather than education and economic status.

Chronic shortage of clotting factor concentrates, exorbitant treatment costs and the poor economic status of patients makes disability an inevitable consequence of haemophilia in India. The prevalence and risk factors for disability were studied in 148 patients with severe haemophilia A registered at five haemophilia clinics in the country. Disability was measured using a scoring method that used a compilation of functional ability, mobility and range-of-motion scores for each patient. Patients ranged in age from 5 to 55 years. Only nine of 148 patients were free of disability. The proportion of disability free patients in the 5-12, 13-24 and 25+ age groups were 14.3%, 4.4% and 0% respectively. The risk factors significantly associated with disability were patients age, socio-economic status, number of persons in the family, family history of haemophilia, frequency of physiotherapy exercises, home use of coagulation factor concentrate and type of blood product(s) used, that is clotting factor concentrate or cryoprecipitate. The study highlights the need to provide coagulation factor concentrates in sufficient amounts to prevent disability, the beneficial role of physiotherapy exercises and the advantage of older patients as peer educators for younger patients. The most important utility of the data is to demonstrate the widespread prevalence of disability amongst patients, its social costs in terms of incomplete education and unemployment, which justifies the need to include haemophilia as one of the conditions under the Disability Act of India.

The number of publications and the scientific interest in lung transplantation has increased rapidly in recent years. Citations of articles published in the field of lung transplantation are increasing and the numbers of uncited articles are fewer compared to the average citations of articles and uncited articles in the field of medicine.

Objectives: The study objective was to assess hydration status by measuring USG among construction workers in Iran. Materials and Methods:The study design was comparative and experimental. Sixty participants were randomly selected from the construction workers from a construction campus with a similar type of work, climate and diet and formed 2 groups (individuals exposed to the sun and non-exposed individuals). TWL and USG were measured in both groups on 2 consequent days, at the beginning, mid and end of the work shift. Results: USG test showed that mean USG was 1.0213±0.0054 in the control group and in the exposed group, where it was significantly higher, it amounted to 1.026±0.005. In the exposed group, 38% of workers had a USG level between 1.026-1.030, representing a higher risk of heat illness and impaired performance and 12.72% had a USG level above 1.030 representing a clinically dehydrated status, while this proportion in the control group was 15.2% and 0.58%, respectively. The mean TWL index measure was 215.8±5.2 W/m 2 for the control group and 144±9.8 W/m 2 for the exposed group, where, again, it was significantly higher. The Pearson correlation measure showed a significant correlation between USG and TWL. Conclusions: Strong correlation between TWL, as an indicator of thermal stress and USG shows that USG can be considered as a predictor of thermal stress. The difference between USG among the exposed and non-exposed workers and the increase in USG during midday work show the sensitivity of this measure in different thermal and climatic conditions, whereas, the high level of dehydration among workers despite acceptable TWL level, shows that heat stress management without considering the real hydration status of workers, is insufficient.
