Insecticide Residues in Soil,Water, and Eggplant Fruits and Farmers’ Health Effects Due to Exposure to Pesticides

Objectives

Eggplant (Solanum melongena L.) is an important vegetable crop that is widely cultivated in the tropical and subtropical areas in Asia. Globally, the top three eggplant producers are China, India, and Egypt. The Philippines has been one of the top 10 eggplant-producing countries based on area planted and crop productivity. This study aims to describe the insecticide residues found in soil, water, and eggplant fruits in eggplant farms in Sta. Maria, Pangasinan.

Methods

The study design is a cross sectional of randomly selected eggplant farms in Sta. Maria, Pangasinan. Soil, water, and eggplant fruits were collected and subjected to gas chromatography (Shimadzu) analysis for multi-pesticide residues.

Results

Farmers from Sta. Maria, Pangasinan were found to be applying a broad spectrum of insecticides on their eggplant crop. Soil samples from 11 (about 42 %) out of the 26 farms tested positive for insecticide residues, six of which from four farms exceeded the acceptable maximum residue limit. These residues were profenofos, triazophos, chlorpyrifos, cypermethrin, and malathion. No insecticide residues were detected from water samples taken from the 26 farms. Cypermethrin and chlorpyrifos were the insecticide residues detected in eggplant fruit samples. A maximum of 20 % of the eggplant samples tested positive for insecticide residues. In the eggplant fruit study, all farmers have been using Prevathon^® for 24 years at a rate of 10 ml/application, and Malathion^® for 25 years at about 16.5 ml/application, respectively equivalent to 0.24 liter-years and 0.413 liter-years of exposure. Similarly, to the findings in the soil and water study, although Brodan^® and Magnum^® were not prevalently applied, the farmers’ liter-years of exposure to these insecticides, and their active ingredients, were highest at about 18.92 and 10.0, respectively. The farmers and farm workers in the soil and water study reported experiencing itchiness of the skin (63.8 %), redness of the eyes (29.3 %), muscle pains (27.6 %), and headaches (27.6 %), as being related to their pesticide exposure.

Conclusion

In summary, a maximum of 20 % of the eggplant samples tested positive for insecticide residues at any one stage of sampling done. The farmers and farm workers also reported of pesticide-related illnesses but none of them sought any medical attention. Intervention to reduce the farmers’ pesticide exposure can focus on the risk factors identified, primarily the toxicity of pesticides used, the unsafe application practices, and the adverse health effects of pesticide exposure.

What can technology do to, and for, family medicine?

Medical technology can be divided into information technology, diagnostic technology, and therapeutic technology. These technologies can enhance the care of patients in a family practice; they also have the potential to diminish or fragment family practice when the technologies can only be provided by specialists. While some family physicians have an aversion to technological advances, we believe it is imperative that family physicians participate in the development of technologies that enhance family practice and improve patient outcomes in primary care practice. These include electronic medical records, decision support systems, tools for managing medical information, and others. Criteria are presented to help determine when these new technologies should be adopted into practice.     

Community-based Organizations’ Capacity to Plan, Implement, and Evaluate Success

Community-based organizations (CBOs) have the potential to promote and sustain health, prevent disease, and address health disparities, but many lack the capacity to do so. An assessment of the 20 CBOs receiving supplemental grant funding from the Pfizer Foundation Southern HIV/AIDS Prevention Initiative indicated a high level of knowledge for developing goals and objectives (mean score=3.08 on a scale of 0 (none) to 4 (extensive)) and high self-assessed abilities to conduct six of 20 specific intervention activities, including the development of community relationships and coalitions. Lower knowledge and skill levels were observed for intervention evaluation. While CBOs of this Initiative have established prerequisite abilities, they have self-acknowledged needs for technical assistance to maximize HIV/AIDS prevention capacity.     

Urgent endoscopic retrograde cholangio-pancreatography: to whom, when and how to perform?

Although the effectivity of an urgent endoscopic retrograde cholangio-pancreatography was documented, some aspects relating to this method are still debated. Timing of this procedure has not been established yet. Indications for urgent endoscopic retrograde cholangio-pancreatography with stone extraction from the common bile duct in patients with biliary pancreatitis remains controversial. Biliary decompression and drainage is the cornerstone of acute cholangitis treatment. The timing of endoscopic retrograde cholangio-pancreatography should be based on the grade of the severity of the disease. Using endoscopic retrograde cholangio-pancreatography, the accurate diagnosis and treatment of bile leaks in a timely manner is imperative to limit associated morbidity and mortality. Difficulty in cannulating the common bile duct is one of the main risk factors for pancreatitis occurring after the procedure. Alternative techniques to facilitate difficult cannulation are discussed. Organized training and introduction of objective measures of the investigator's competence are emphasized to improve the performance of the procedure in Hungary.     

An opportunity to refine our understanding of “response shift” and to educate researchers on designing quality research studies: response to Ubel,Peeters, and Smith

There is no advantage at this time to abandon the term “response shift” as suggested by Ubel et al. (Qual Life Res, 2010). The term is well known in the research field and has impacted the way we think about measuring quality of life (QOL) longitudinally. However, Ubel et al. (Qual Life Res, 2010) have provided the incentive to start an open dialogue on the subject with opportunities to refine the language of response shift and educate researchers. In this article, we identify opportunities in designing research studies to minimize or account for response shifts by considering the (1) selection of QOL concepts to measure, (2) questionnaires used to assess the QOL concepts, (3) design of the research study, (4) target population, and (5) analyses and reporting of results. Careful consideration of each of these issues will help us identify new methodologies and improved study designs that will move the QOL research field forward.     

Do Perceived Cues,Benefits, and Barriers to Physical Activity Differ Between Male and Female Adolescents?

A four-page survey was administered to 535 adolescents at two single-sex (one male, one female) high schools in Cincinnati, Ohio, to examine whether perceptions of physical activity differed by gender. More specifically, the survey assessed perceived cues, benefits, and barriers to exercising. Results indicated that the most helpful cue to physical activity for both female and male students was "having a friend to exercise with." The most commonly reported benefit of exercising among females was "to stay in shape," whereas the most commonly reported benefit to exercising among males was "to become strong." Among females, the most common barrier to exercising was "having no time to exercise," whereas males were most likely to report "wanting to do other things with my time." Multivariate analyses of covariance revealed that perceived cues, benefits, and barriers to physical activity differed significantly based on gender. Recommendations on specific strategies to increasing male and female adolescent physical activity levels are offered.     

Promoters and Barriers to Fruit, Vegetable, and Fast-Food Consumption Among Urban, Low-Income African Americans��A Qualitative Approach

To identify promoters of and barriers to fruit, vegetable, and fast-food consumption, we interviewed low-income African Americans in Philadelphia. Salient promoters and barriers were distinct from each other and differed by food type: taste was a promoter and cost a barrier to all foods; convenience, cravings, and preferences promoted consumption of fast foods; health concerns promoted consumption of fruits and vegetables and avoidance of fast foods. Promoters and barriers differed by gender and age. Strategies for dietary change should consider food type, gender, and age.Diet-related chronic diseases—the leading causes of death in the United States^1,2—disproportionately affect African Americans^3–7 and those having low income.^8–10 Low-income African Americans tend to have diets that promote obesity, morbidity, and premature mortality^3,4,11,12; are low in fruits and vegetables^13–18; and are high in processed and fast foods.^19–23Factors that may encourage disease-promoting diets include individual tastes and preferences, cultural values and heritage, social and economic contexts, and systemic influences like media and marketing.^24–30 Because previous research on dietary patterns among low-income African Americans has largely come from an etic (outsider) perspective, it has potentially overlooked community-relevant insights, missed local understanding, and failed to identify effective sustainable solutions.³¹ Experts have therefore called for greater understanding of an emic (insider) perspective through qualitative methods.³¹ However, past qualitative research on dietary patterns among low-income African Americans has been limited, focusing mostly or exclusively on ethnic considerations,^28,29 workplace issues,¹⁰ women,^32–38 young people,^38,39 or only those with chronic diseases^34,36,39,40 and neglecting potentially important differences by age and gender.^31,41–43To build on prior research, we conducted interviews in a community-recruited sample using the standard anthropological technique of freelisting.^44–46 Our goals were (1) to identify the promoters of and barriers to fruit, vegetable, and fast-food consumption most salient to urban, low-income African Americans and (2) to look for variation by gender and age.     

A will to health? Drinking,risk and social class

This article explores risk conceptions related to alcohol use among Danes who drink ‘too much’ (based on the National Health Board’s standards for safe drinking). It analyses drinking patterns and risk management strategies among interviewees from different socio-economic backgrounds, and explores the differences between the behaviours and conceptions of these individuals and the risk advice and definitions provided by health agencies. The article shows that people from different socio-economic backgrounds respond differently to the neo-liberal strategy of alcohol risk minimisation, with middle- and upper-class participants being more in tune with the public health ethos of alcohol consumer ‘autonomisation’ and ‘responsibilisation’. Cutting across socio-economic differences, though, are risk conceptions that clash with the public health model of risk prevention. While the risk communication of the health agencies builds on the logic of ‘a will to health’, drinkers at relatively high consumption levels tend to prefer other rationales, associating alcohol use with socialisation, pleasure and relaxation, and defining alcohol risks in terms of ‘addiction’ rather than detrimental health effects. The article contributes to the discussion of the ‘prevention paradox’, showing that rational initiatives at a general population level are not always comprehended as such at the individual level.     

Chronic,Inhalation Exposure of Rats,Rabbits , and Monkeys to 1 , 2 , 4–Trichlorobenzene

Three groups composed of rats, rabbits, and monkeys were exposed for 26 weeks to 1,2,4-trichlorobenzene (-TCB), and one group of each species was used as a control group. TTie nominal exposure concentrations of 1,2,4-TCB were 25.0, 50.0, and 100.0 ppm. Pulmonary function and operant behavior tests in monkeys, ophthalmoscopic examinations in rabbits and monkeys, and measurement of body weights and hematologic and serum biochemical determinations in all species were conducted before and during the exposure period. At termination of 1, 3, and 6 months of exposure, microscopic examination of selected rat tissues was performed. Microscopic changes were seen in the parenchymal cells of livers and kidneys from all groups of rats exposed to 1,2,4-TCB when sacrificed after 4 and 13 weeks of exposure, but no exposure-related abnormalities or other effects were seen after 26 weeks of exposure in any species.     

Prenatal Exposure to Lead, δ-Aminolevulinic Acid,and Schizophrenia: Further Evidence

Background

A previously conducted study of prenatal lead exposure and schizophrenia using δ-aminolevulinic acid, a biologic marker of Pb exposure, in archived maternal serum samples collected from subjects enrolled in the Childhood Health and Development Study (1959–1966) based in Oakland, California, suggested a possible association between prenatal Pb exposure and the development of schizophrenia in later life.

Objectives

In the present study we extend these findings using samples collected from the New England cohort of the National Collaborative Perinatal Project (1959–1966). Using similar methods, in this study we found results that suggest a comparable association in this cohort.

Methods

We pooled matched sets of cases and controls from both the California and New England sites using a multilevel random-intercept logistic regression model, accounting for matching and site structure as well as adjusting for maternal age at delivery and maternal education.

Results

The estimated odds ratio for schizophrenia associated with exposure corresponding to 15 μg/dL of blood Pb was 1.92 (95% confidence interval, 1.05–3.87; p = 0.03).

Conclusion

Although several limitations constrain generalizability, these results are consistent with previous findings and provide further evidence for the role of early environmental exposures in the development of adult-onset psychiatric disorders.
