BackgroundPesticide exposure possesses risk of genotoxicity to humans, particularly farmers. Despite accumulating evidences linking genotoxicity to pesticide exposure, epidemiological studies to address pesticide toxicity in occupationally exposed farmers in Malaysia remain underreported. Thus, this study was aimed to determine the presence of nuclear abnormalities through the assessment of micronucleus (MN) and binucleus (BNu) frequencies in exfoliated buccal epithelial cells from farmers who were exposed to pesticides. A cross-sectional study of farmers among different agricultural activities farmers in Bachok and Pasir Puteh, Kelantan, North East of Peninsular Malaysia was done to evaluate the presence of nuclear abnormalities and its correlation with their health status and farming activities.ResultsAnalysis of buccal cells revealed that the frequency of MN was significantly higher (p < 0.05) in farmers as compared to controls. In contrast, no significant difference (p > 0.05) was observed for BNu frequency in between groups. Correlation analysis showed that apart from a significant (p < 0.05) and positive correlation between the duration of fertilizers exposure and frequencies of MN (r = 0.42, P = 0.001) and BNu (r = 0.37, P = 0.02), no other correlation of various confounding factors on the formation of MN and BNu were observed.ConclusionIn conclusion, pesticide and fertilizers exposure may contribute to the promotion of nuclear anomalies among Malaysian farmers who are engaged in mixed plantation activities. Further assessment of larger populations is important to address and overcome the potential risk of pesticide-induced genotoxicity.

Heavy metals, particularly cadmium, lead, and arsenic, constitute a significant potential threat to human health. This study was conducted to determine the levels of cadmium, lead, and arsenic in nail samples from farmers at Muda Agricultural Development Authority (MADA), Kedah, Malaysia, and evaluate factors that can contribute to their accumulations. A total of 116 farmers participated in this study. Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze concentration of heavy metals in the nail samples and questionnaires were given to participants to get demographic, health status, and their agricultural activities data. In this paper, the level of heavy metals was within the normal range and varies according to demographic factors. We found that there were significant correlations between working period with level of lead and arsenic (r = 0.315 and r = 0.242, resp., P < 0.01) and age with lead level (r = 0.175, P < 0.05). Our findings suggested that agricultural activities could contribute to the accumulation of heavy metals in farmers. Hence, the control of environmental levels of and human exposure to these metals to prevent adverse health effects is still an important public health issue.

Abstract Introduction: Little is known about how smokers respond cognitively and emotionally to the experience of “late” relapse after the acute withdrawal phase. This study assessed the kinds of thoughts and feelings that emerge in order to provide a basis for quantitative research assessing prevalence of different types of response and implications for future quit attempts. Methods: Face-to-face in-depth interviews were conducted among 14 people attending a quit smoking clinic in Malaysia who had relapsed after at least 6 weeks of abstinence. Transcripts were analyzed using thematic analysis to enable emergence of important aspects of the experience. Results: Following relapse, smokers often engaged in rationalizations and activities to minimize worry about the harmful effects of smoking by switching to a lower-tar cigarette, reducing the number of cigarette smoked, attempting to reduce cigarette smoke inhalation, comparing themselves with other smokers, and minimizing the health risks associated with smoking. In some cases, smokers retained a “non-smoker” identity despite having relapsed. Conclusion: Smoking relapsers rationalize their failure to quit and minimize their health risk in order to protect their image as non-smokers while it remains a source of identity conflict.

Chromium is an essential mineral and cofactor for insulin that plays an important role as hormone that helps in the blood sugar regulation. Kelantanese were known as sugar-based food consumer. Farmers have high risk of health problem because of exposure to pesticide and sugar-based food intake can give an effect on the level of chromium. The objective of this research was to study the status of chromium among farmers exposed to pesticides and fertilizer in Kelantan. This was a cross-sectional study that was done at Bachok and Pasir Puteh, Kelantan. Respondent were 113 farmers who had been exposed to pesticides or fertilizer for not less than one year. Subjects were interviewed to obtain information on their demographic data by using validated knowledge, attitude and practice (KAP) questionnaire. Nails and hair chromium levels were analyzed by using acid digestion method and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). Results showed that 81.4% were male while 18.6% were female. Farmer’s chromium level in nails (125.82 ± 47.81 μg/L) and hair (39.63 ± 5.70 μg/L) were very much lower when compared with standard value in nails (6200 μg/L) and hair (100-2500 μg/L). No signifi cantly differences (p > 0.05) were found between chromium level according to gender, age, level of pesticide exposure, dietary chromium intake and blood glucose. Chromium levels in nails and hair of farmers who smoke was signifi cantly lower (p < 0.05) than non-smoking farmers. As a conclusion, the level of chromium among farmers in Bachok and Pasir Puteh, Kelantan are lower than normal reference and farmers should stop smoking because smoking can lower the chromium level.
