Analysis of Trends of the Types of Pesticide Used, Residues and Related Factors among Farmers in the Largest Vegetable Producing Area in the Philippines.

Abstract: The objective of study is to provide an analysis of data trends on the type of pesticide used, exposure factors, and the pesticide-related concerns among the farmers from 2005 to 2010 in one of the largest vegetable producing areas in the Philippines. This is to determine and analyze changes that have occurred for the last five years in order to provide necessary basis in promoting safe usage of pesticides. It is shown in the studies that the most commonly used type of pesticide was Tamaron (methamidophos) which is an organophosphate. The top five pesticide-related symptoms confirm findings in other studies. The risk factors to pesticide exposure were also identified in the reviewed studies such as improper mixing and loading of pesticides, and re-entering previously sprayed area. Pesticide residues were also found in vegetables, soil and water samples. This points to environmental contamination due to pesticide. It is suggested that government agencies implement programs on monitoring, surveillance, information dissemination, and training on proper use of pesticides, and seek alternative farming such as organically grown vegetables, or use of integrated pest management as well as good agricultural practices.

Feasibility of a Comprehensive Targeted Cholera Intervention in The Kathmandu Valley, Nepal

Abstract: A comprehensive targeted intervention (CTI) was designed and deployed in the neighborhoods of cholera cases in the Kathmandu Valley with the intent of reducing rates among the neighbors of the case. This was a feasibility study to determine whether clinical centers, laboratories, and field teams were able to mount a rapid, community-based response to a case within 2 days of hospital admission. Daily line listings were requested from 15 participating hospitals during the monsoon season, and a single case initiated the CTI. A standard case definition was used: acute watery diarrhea, with or without vomiting, in a patient aged 1 year or older. Rapid diagnostic tests and bacterial culture were used for confirmation. The strategy included household investigation of cases; water testing; water, sanitation, and hygiene (WASH) intervention; and health education. A CTI coverage survey was conducted 8 months postintervention. From June to December of 2016, 169 cases of Vibrio cholerae O1 were confirmed by bacterial culture. Average time to culture result was 3 days. On average, the CTI Rapid Response Team (RRT) was able to visit households 1.7 days after the culture result was received from the hospital (3.9 days from hospital admission). Coverage of WASH and health behavior messaging campaigns were 30.2% in the target areas. Recipients of the intervention were more likely to have knowledge of cholera symptoms, treatment, and prevention than non-recipients. Although the RRT were able to investigate cases at the household within 2 days of a positive culture result, the study identified several constraints that limited a truly rapid response.

Multiple Interactions of Hazard Exposures, Role Stressors and Situational Factors, and Burnout Among Nurses

Abstract: This was a cross-sectional study which looked into the interaction between situational factors, role stressors, hazard exposure and personal factors among 135 nurses in the Philippine General Hospital. More than half (58.5%) of the respondents reported being ill due to work in the past year, and 59.3% missed work because of an illness. Regression showed factors associated with burnout were organizational role stress, hazard exposure, self-efficacy, age, number of working years, illness in the past 12 months, migraine, dizziness, sleep disorder, cough and colds, and diarrhea. After multiple regression analysis, organizational role stress (p = .000), migraine (p = .001), age (p = .018) and illness in the past 12 months (p = .000) were found to be significant predictors of burnout. The contribution of the study is in advancing new concepts in the already existing framework of burnout, and thus, assisting nurses and hospital administration in on controlling this problem.

Structural equation modeling of the inflammatory response to traffic air pollution.

Abstract: Several epidemiological studies have reported conflicting results on the effect of traffic-related pollutants on markers of inflammation. In a Bayesian framework, we examined the effect of traffic pollution on inflammation using structural equation models (SEMs). We studied measurements of C-reactive protein (CRP), soluble vascular cell adhesion molecule-1 (sVCAM-1), and soluble intracellular adhesion molecule-1 (sICAM-1) for 749 elderly men from the Normative Aging Study. Using repeated measures SEMs, we fit a latent variable for traffic pollution that is reflected by levels of black carbon, carbon monoxide, nitrogen monoxide and nitrogen dioxide to estimate its effect on a latent variable for inflammation that included sICAM-1, sVCAM-1 and CRP. Exposure periods were assessed using 1-, 2-, 3-, 7-, 14- and 30-day moving averages previsit. We compared our findings using SEMs with those obtained using linear mixed models. Traffic pollution was related to increased inflammation for 3-, 7-, 14- and 30-day exposure periods. An inter-quartile range increase in traffic pollution was associated with a 2.3% (95% posterior interval (PI): 0.0-4.7%) increase in inflammation for the 3-day moving average, with the most significant association observed for the 30-day moving average (23.9%; 95% PI: 13.9-36.7%). Traffic pollution adversely impacts inflammation in the elderly. SEMs in a Bayesian framework can comprehensively incorporate multiple pollutants and health outcomes simultaneously in air pollution-cardiovascular epidemiological studies.
