ABSTRACT
Background: Overweight among adolescents has high prevalence on the eastern part of India, especially West Bengal. Objectives: The current study was conducted to estimate and compare the effects of different dietary habits and habits related to physical activity in the development of overweight and obesity among rural schoolgoing adolescents. Methods: A prospective repeated measures study was conducted on 645 schoolgoing adolescents from selected rural government-aided schools from June 2017 to December 2017. Dietary habits of the students and physical activity-related factors were the major predictors. Adjusting for the age and sex of the participants, effect of these factors on the development of overweight and obesity was analyzed by generalized estimating equations for 2 repeated measures, taken 6 months apart. Results: Most of the respondents were aged ?16 years (56.90%), female (52.87%), Hindu (76.74%), from a nuclear family (76.74%), and studying in the secondary level (57.68%). There was a stark rise in proportion of overweight from 0.93% to 7.44%. The prevalence of unhealthy dietary habits was 68.99% at the baseline, and 66.82% on follow-up. The overall prevalence of inadequate physical activity increased to 48.68% from 47.91%. Female gender and older age group were at higher risk of being overweight or obesity. Overall fast food showed highest risk (3.04, 95% confidence interval [CI]: 1.86–4.95), while among the boys, it was with less vegetable consumption (4.64, 95% CI: 1.84–11.69). Conclusions: Strong evidence was generated of dietary practices being more rigidly related to overweight among the adolescents. Healthy dietary practices coupled with physical activity should be promoted to mitigate the risk of obesity.
ABSTRACT
The present study shows overall prevalence (64%) of reproductive tract infection among adolescent girls, based on self-perceived symptoms. Mean age of respondents were found to be 17.8 +/- 0.82 years and mean age at marriage and mean age at first pregnancy were 17.2 years and 17.5 years respectively; 35.35% of girls in the present study were married. In addition, no significant difference was observed between unmarried (60.10%) and married (71.17%) reproductive tract infection groups. Moreover, no significant association was present in prevalence of reproductive tract infection between the Muslim (67%) and the Hindu (60%). Highest prevalence (84.06%) of reproductive tract infection was observed among illiterate girls and with improvement of educational status there was decrease in the prevalence and the association was found highly significant. Significantly, higher prevalence (72%) was observed among members of family size 7 and above.

Fragile X syndrome is the most common of the inherited disorders causing mental retardation. This disorder results from an abnormal expansion in (CGG)n in repeat found in the coding sequence of the FMRI gene, located at Xq 27.3. Previously it was detected by Karyotyping. With the advent of Molecular Biology PCR, has become the best method in the diagnosis of this disorder. This is a case report of a family with this disorder detected by PCR.

Over a hundred years have elapsed since Vibrio cholerae, the etiological agent for the disease cholera, was discovered by Robert Koch. Ever since then serious efforts have been made to develop prophylactic measures to combat the disease without much success. Seven pandemics have so far been reported and cholera still remains a public health problem in developing countries. Several strategies have been adopted to develop vaccines against the disease and many of these vaccines have undergone field trials. During the last two decades, an enormous amount of information has accumulated regarding the organism V. cholerae, its virulence factors, including cholera toxin, and the molecular basis of its pathogenicity. In recent years, with the advent of recombinant DNA technology and major breakthroughs in molecular biology and immunology, a new dimension has been given to the design of vaccine strains. The second generation live oral vaccines will perhaps soon replace the long-used first generation parenterally administered killed whole cell vaccines which offered protection for not more than three months. All the recombinant vaccines tested so far produced adverse reactions in volunteers, although they provided varying degrees of protection upto about one year of surveillance. Parallel to the trials of live oral vaccines, combination vaccines comprising killed whole cells and purified B subunit of cholera toxin was also tried. These vaccines had minimal side-effects but the efficacy was not upto expectations. From the failure of each vaccine strain, new information had emerged and improved strategies were adopted.(ABSTRACT TRUNCATED AT 250 WORDS)
