Relationship between Parental Emotional Styles and Family Values to Anxiety Level among Primary School Children

@#Introduction: Childhood anxiety is one of the common mental health problems in children. Untreated childhood anxiety will lead to a higher risk of developing mental health problems in adulthood. Thus, this study aimed to investigate the relationship between parental emotional styles and family values to anxiety level among primary school children. Methods: A cross-sectional study was conducted in a selected primary school in Kelantan, Malaysia. A set of questionnaires consisted of the Revised Child Anxiety and Depression Scale–Parents’ Report (RCADS-P 25), the Parental Emotional Style Questionnaire (PESQ), and the Asian Family Characteristics Scale (AFCS) was used for assessing anxiety, parental emotional styles, and family values, respectively. Data were collected via an online survey using Google Form, and were analysed using Multiple Linear Regression (MLR) to determine the factors associated with childhood anxiety. The significance value was set at p < 0.05. Results: A total of 150 parents of primary school children from the selected school was involved in this study. The majority of respondents were females (82.0%), married (94.7%), hold a degree (66.7%), and were working in the government sector (60.0%). Most of the respondents’ child were twelve years old (20.7%) and males (62%). Based on the MLR, emotional dismissing parental style (p = 0.025) and family values (p = 0.016) were significantly associated with anxiety in these children. Conclusion: Emotional dismissing parental style and family values were significant predictors of anxiety in primary school children. Future intervention research on childhood anxiety is needed.

Acetylcholinesterase Levels in Farmers Exposed to Pesticides in Malaysia.

Agriculture is an important component of the Malaysian economy. Pesticides are widely used by farmers to increase crop production. Acetylcholinesterase (AChE) is known to play an important role in the degradation of acetylcholine (ACh) at the neuromuscular junction of the nervous system. The purpose of this study was to determine the effect of pesticide exposure on serum levels of AChE of farmers. A cross-sectional study was conducted. A total of 95 farmers from Kelantan (n = 49) and Selangor (n = 46) aged between 23 and 71 years were recruited. AChE concentration was measured by spectrophotometry. The results of this study showed that the mean AChE concentrations in farmers from Kelantan and Selangor were 2,715 and 2,660 U/L, respectively, significantly different (p < 0.05) from normal reference value (3500 U/l). Pearson correlation test showed a moderate correlation between AChE level and age (r = - 0.551) and a strong correlation between AChE level and working period (r = -0.872) in farmers in Kelantan. AChE levels in Selangor were also moderately correlated with age (r = -0.353) and working period (r = -0.515). In conclusion, increasing age and long-term pesticide exposure reduce AChE levels in farmers.

Fenitrothion induced oxidative stress and morphological alterations of sperm and testes in male sprague-dawley rats

OBJECTIVE: Fenitrothion residue is found primarily in soil, water and food products and can lead to a variety of toxic effects on the immune, hepatobiliary and hematological systems. However, the effects of fenitrothion on the male reproductive system remain unclear. This study aimed to evaluate the effects of fenitrothion on the sperm and testes of male Sprague-Dawley rats. METHODS: A 20 mg/kg dose of fenitrothion was administered orally by gavages for 28 consecutive days. Blood sample was obtained by cardiac puncture and dissection of the testes and cauda epididymis was performed to obtain sperm. The effects of fenitrothion on the body and organ weight, biochemical and oxidative stress, sperm characteristics, histology and ultrastructural changes in the testes were evaluated. RESULTS: Fenitrothion significantly decreased the body weight gain and weight of the epididymis compared with the control group. Fenitrothion also decreased plasma cholinesterase activity compared with the control group. Fenitrothion altered the sperm characteristics, such as sperm concentration, sperm viability and normal sperm morphology, compared with the control group. Oxidative stress markers, such as malondialdehyde, protein carbonyl, total glutathione and glutathione S-transferase, were significantly increased and superoxide dismutase activity was significantly decreased in the fenitrothion-treated group compared with the control group. The histopathological and ultrastructural examination of the testes of the fenitrothion-treated group revealed alterations corresponding with the biochemical changes compared with the control group. CONCLUSION: A 20 mg/kg dose of fenitrothion caused deleterious effects on the sperm and testes of Sprague-Dawley rats.
