THE POTENTIAL EFFECTS OF A COMMUNITY DEVELOPMENT PROGRAM ON DEMOGRAPHIC VARIABLES IN HIMALAYAN INDIAN VILLAGES

A community development program operating in the mountains of North India was studied to assess its potential effects on mortality, fertility and migration patterns in the community which it served. The development program operated in Jaunpur Block, Tehri-Garhwal District, Uttar Pradesh State. Two comparable villages in the district were studied. The development program had been working in one for two years, and the other was completely untouched by the program.^ Since not enough time had elapsed since the beginning of the development program's work for any effects on demographic patterns to be visable in Jaunpur Block, this study looked to attitudes of village residents as indicators of future demographic trends. Existing demographic patterns and their interrelationship with socio-religious customs were examined in the test village. A questionnaire was then administered to ascertain attitudinal differences between the residents of the test village and the control village.^ The primary work of the community development program was to train women as village health workers. The results of the attitudinal comparison of the residents of the two villages showed a marked difference in attitudes relating to the position of women in society. The data showed a higher esteem for women in the test village than in the control village, and it is argued that this difference may be attributable to the work of the development program.^ Predicting future demographic trends in Jaunpur Block on the basis of the observed difference in villagers' attitudes toward the status of women is speculatory. Jaunpur Block appears to be in the demographic stage of pre-transition, maintaining relatively high rates of both mortality and fertility. Based on demographic transition theory the next significant change in demographic patterns in Jaunpur is predicted to be a decline in mortality, and an increase in the status of women is unrelated to this prediction.^ The community development program which was studied terminated unexpectedly during the time of this study. A case study of the program's final months is presented, and speculation on the future course of demographic trends in Jaunpur Block is related to the possible alternatives for future development in the area. ^

Tuberculosis in persons with concomittant diseases in Houston, Texas, 2004 to 2008

The purpose of this study is to evaluate characteristics of tuberculosis (TB) in diabetics and persons infected with HIV from 2004 to 2008 in Houston, Texas. This analysis will allow us to identify demographic trends. Previous studies have shown that in general, there is a higher risk for HIV+ persons to develop active TB, or to re-activate latent TB, as they progress in their HIV infection. In addition, similar to HIV, diabetes mellitus (DM) weakens the immune system so that persons with DM have also been shown to have a tendency to develop TB. This analysis will examine three areas of research: (a) to explore existing TB trends in Houston/Harris County and associated characteristics, (b) to ascertain the common risk factors of DM and HIV that are correlate with TB infections, and (c) from the analysis of the data, to determine if subsequent TB prevention programs are needed for specific subgroups.^

SABR for early-stage lung cancer: Early-adoption and future directions

Early-stage lung cancer incidence among older adults is expected to increase due to demographic trends and CT-based screening, yet optimal treatment of lung cancer in the elderly remains controversial. There are several accepted strategies for treating lung cancer including surgery, conventional radiation, and stereotactic ablative body radiotherapy (SABR). However, there are currently no randomized controlled trials to help distinguish the comparative effectiveness of these various strategies. This is an unfortunate omission as lung cancer causes the most deaths among all cancers in the United States (as well as the entire world). SABR holds particular promise as it is a completely non-invasive, ambulatory technique for achieving cure without an operation, thus avoiding the risks of surgery and the associated pre-operative and post-operative costs. To provide fair view of the potential effect on SABR on controlling lung cancer in the United States, a systematic review of SABR with a focus on its achieved outcomes, toxicities, and comparison to conventional radiation and surgical options is presented. ^

Trends in anti-tuberculosis drug resistance from 2003--2007 at Pham Ngoc Thach tuberculosis and lung disease hospital, Ho Chi Minh City, Vietnam

Vietnam is one of the countries with the highest prevalence and incidence of tuberculosis (TB) in the world (1). Although Vietnam has had many successes in TB control, it still faces the challenge of drug resistant and multidrug-resistant tuberculosis (MDR-TB). MDR-TB appears to be relatively stable, but data on MDR-TB continues to be scarce and routine testing of all isolates for drug susceptibility is not performed under Vietnam's National Tuberculosis Program (6). Pham Ngoc Thach Hospital (PNT), the leading tuberculosis and lung disease hospital in Ho Chi Minh City, serves as a reference hospital and laboratory for both Ho Chi Minh City and the Southern Vietnam region. This study is an unmatched, nested case-control study consisting of a secondary analysis of a previously created dataset composed of drug susceptibility and basic demographic data from a cohort of patients diagnosed with tuberculosis at PNT from 2003 through 2007 in order to calculate the prevalence of resistance among acid-fast bacilli smear-positive patients. The susceptibility records for the years 2003-2004 were not representative of the entire population, but over the years 2005-2007 the investigator found a decrease in resistance to all primary TB drugs on which records were available, as well as MDR-TB. Overall, females showed a higher proportion of resistance to TB drugs than males, and females had a greater likelihood of presenting with MDR-TB than males (OR=1.77). Persons 35-54 had greater likelihood of having MDR-TB than younger and older age groups. Among the population with HIV data, HIV-positivity was associated with greater likelihood of MDR-TB (OR=1.70, 95% CI=0.97-3.11). This study shows that rates of TB drug resistance are high, but declining, in one of Vietnam's largest TB hospitals, and that females and HIV-positive individuals are possible high-risk groups in this population.^
