The study was built on Lewin’s theory of change and Stakeholders theory by Freeman. Descriptive research design was used to determine the effects of variables. The target population was the fellowship, church leaders and members of fellowship groups in AGC churches Anaimoi sub-county, Kericho County, Kenya. Anaimoi is divided into 6 wards with each having an average of 10 AGC churches. The fellowship groups in 18 churches were used as a sample. Strata random sampling was used to select the respondents. Data was collected using structured questionnaires and interviews. The study was analysed through descriptive statistics with the help of SPSS and presented in pie charts, tables and graphs. Interpretation was made based on research objective. A pilot study was carried out by choosing one small group fellowship to determine the reliability and validity of research instruments. Cron...

Despite a recent rise in CRC screening there remains an increasing demand for colonoscopy, yet a limited supply of gastroenterologists who can meet this need. To determine if a mid-career general internist (GIN) could be trained to perform high-quality colonoscopes via an intensive training programme. A GIN trained 2-3 days/week, 4-5 hours/day, for 7 months with an experienced gastroenterologist. Their independent performance was then compared with that of a gastroenterology attending (GA), with and without a gastroenterology fellow (GF). The primary outcome was to compare caecal intubation rates, adenoma detection rates (ADRs), interval CRC rates and complications between the three groups. 989 patients were initially included in the study, and 818 were included in the final analysis. Caecal intubation rates were 95%, 94% and 93% for the GIN, GA+GF and GA, respectively (p=0.31). The overall polyp detect...

Increasing evidence suggests, however, differential burdens by gender and age. The purpose of the authors' research was to determine if gender-related difference exists among children in a region plagued with poor air quality and if increased exposure to pollutants from a major goods movement rail yard influences the relationship. Using a cross-sectional study design, the authors provided respiratory screening for children at two elementary schools. Compared to females, males were at significantly greater odds of exhibiting elevated fractional exhaled nitric oxide (FeNO) but less likely to exhibit reduced lung volume. Even in an area of overall poor air quality, the authors found that male children were a vulnerable subpopulation for greater elevated FeNO, while females were at increased risk for reduced lung capacity. Understanding differential burdens in vulnerable subpopulations is critical to providing...

The heat generated while drilling may reach thresholds high enough to cause osteonecrosis. This can compromise implant stability. Orthopedic drill bits are several orders more expensive than their similarly sized, publicly available industrial counterparts. We hypothesize an industrial bit will generate less heat during drilling, and the bits will not generate more heat after multiple cortical passes. We compared 4 4.0 mm orthopedic and 1 3.97 mm industrial drill bits. Three types of each bit were drilled into porcine femoral cortices 20 times. The temperature of the bone was measured with thermocouple transducers. The heat generated during the first five drill cycles for each bit was compared to the last five cycles. These data were analyzed with analysis of covariance. The industrial drill bit generated the smallest mean increase in temperature (2.8 ± 0.29°C) p<0.0001. No significan...
