This study examined the effectiveness of Thailand’s Q-GAP initiative in raising cabbage farmers’ awareness regarding food safety assurance and improving their pesticide use practices by comparing 41 Q-GAP-certified and 90 uncertified farmers in Chiang Mai Province, Thailand. The research methods included a questionnaire survey administered to the participating farmers and laboratory pesticide residue testing of their cabbage produce samples. The research found that certified farmers had a significantly more heedful attitude than uncertified farmers toward the effects of pesticide use on the users, consumers, and the environment. This is supported by the higher level of Q-GAP training experiences. Compared to uncertified farmers, a significantly lower proportion of certified farmers also applied either insecticide, fungicide, or herbicide, with significantly less frequencies when including in the analysis those who did not use the particular pesticide. In the pesticide residue analysis, no significant difference was found between the two types of farms regarding the number of farms detected with minimum residue level exceedance in the sample produce and regarding the results of the aggregate organophosphate pesticide analysis. However, it was found that the produce of the uncertified farmers contained significantly more residue in the aggregate synthetic pyrethroid pesticide analysis as compared to that of the certified farmers. These findings indicate the Q-GAP-certified farmers’ progress in process control from earlier Q-GAP studies on compliance. However, considering the limited achievements of certified farmers in pesticide handling and recordkeeping, and those of the Department of Agriculture officers in auditing, there is a need for more governmental efforts, especially in these areas.

The purpose of this study was to investigate how the COVID-19 pandemic affects the organic rice production system in four districts of Chiang Mai Province. Eight organic farmers were purposefully chosen as informants because they have possessed forty-seven resilience components (SERCs) needed to cope with all kinds of social-ecological change. They were asked using a structured questionnaire to assign each SERC’s contribution value before and after the COVID-19 pandemic, in which each time scoring must be coupled with entailed explanations. Then, the paired samples t-test was run to compare such means of SERCs’ contribution values to examine whether their organic rice production’s resilience was affected by the pandemic and how. Results showed the means of SERCs before and after the pandemic have no significant difference as the p-value is 1.00 at the 95% confidence interval. This meant the pandemic does not influence the organic rice production’s social-ecological resilience. But several practices and qualifications were found varying from the original to make production more suitable. The dependence on household labor and that on mutual labor exchange were respectively increased and decreased in their roles in resilience building. Labor availability was interrupted by the social distancing protocol that had restricted people from gathering. Besides, the household accounts recording was adopted more than usual for being seen as a solution to improving the household economy during the time of financial vulnerability. Importantly, relying on local goods was remarkably recognized for increased importance. This was an attempt to get access to materials possibly free from the COVID-19 contamination because of the absent transportation. These findings provide two key interests. They can be applied as a framework not only to strengthen agricultural resilience but also to propose a blueprint of coping mechanisms against the pandemic at a mass scale.

This quasiexperimental study was designed to determine the effectiveness of a participatory program on pesticide use behavior and blood cholinesterase levels. The participants were 18–60 years old, living in Thung Satok subdistrict, San Pa Tong District, Chiang Mai Province. Eighty subjects, including 32 farmers and 48 consumers, were recruited to participate in the study voluntarily by a purposive sampling technique. Data concerning each individual’s behaviors were collected using questionnaires, and blood cholinesterase levels were obtained from whole blood finger, providing whole blood pre and postexperiment. The data were analyzed using Fishers’ exact and paired t-tests, for the problem situations were independently analyzed. The results show that the participatory process made it possible to improve methods for the prevention of the unhealthy effects of pesticides. After participating in the activities, both groups showed significantly higher scores in before and after knowledge ( P < 0.05 ) and a decrease in pesticide contamination in their bodies as a result of the measurement of average cholinesterase which increased significantly ( P < 0.001 ). In conclusion, the participatory program was applied to solve health problems from chemical hazards. The program can raise awareness about chemical toxicity, leading to the modification of the related behavior toward chemicals and reduction of the contamination of chemicals in the body. Therefore, the adoption of participatory processes can effectively solve problems related to chemical hazards that affect health.

Abstract The uneven distribution of pesticide residues among the treated objects leads to an inevitable variability of pesticide residue levels measured in the samples, which may significantly contribute to the combined uncertainty of the analytical results. A total of 8844 unit-crop residue data derived from 57 lots and 19 field trials were evaluated to determine the characteristic features of residue distribution in unit crops and composite samples. The average residue levels and the corresponding coefficient of variation (CV) values obtained for individual units taken from a given lot showed wide variation from lot to lot. There was no significant difference between the CVs of residue levels in sample sets of various unit crops or composite sample populations of different sizes taken from various crops. The CV values for levels of residues taken from individual lots followed normal distribution. Very good correlation was found between the CVs of the parent and sample populations. The experimentally obtained values were very close to those expected on the basis of the central limit theorem. The estimated typical relative standard uncertainties of sampling medium-size crops for pesticide residue analysis in the cases of sample sizes of 5, 10, and 25 were 37, 25, and 16%, respectively.

Carbapenem-resistant Acinetobacter baumannii (CRAB) is one of the most commonly reported nosocomial infections in cancer patients and could be fatal because of suboptimal immune defenses in these patients. We aimed to compare clinical response, microbiological response, nephrotoxicity, and 30-day mortality between cancer patients who received short (<14 days) and long (≥14 days) courses of colistin for treatment of CRAB infection. A retrospective cohort study was conducted in cancer patients with CRAB infection who received short or long courses of colistin between 2015 to 2017 at Chiang Mai University Hospital (CMUH). A total of 128 patients met the inclusion criteria. The results of this study show that patients who received long course of colistin therapy had a higher rate of clinical response; adjusted odds ratio (OR) was 3.16 times in patients receiving long-course colistin therapy (95%CI, 1.37–7.28; p value = 0.007). Microbiological response in patients with long course was 4.65 times (adjusted OR) higher than short course therapy (95%CI, 1.72–12.54; p value = 0.002). Moreover, there was no significant difference in nephrotoxicity (adjusted OR, 0.91, 95%CI, 0.39–2.11; p value = 0.826) between the two durations of therapy. Thirty-day mortality in the long-course therapy group was 0.11 times (adjusted OR) compared to the short-course therapy group (95%CI, 0.03–0.38; p value = 0.001). Propensity score analyses also demonstrated similar results. In conclusion, cancer patients who received a long course of colistin therapy presented greater clinical and microbiological responses and lower 30-day mortality but similar nephrotoxicity as compared with those who a received short course. Therefore, a long course of colistin therapy should be considered for management of CRAB infection in cancer patients.

A cross-sectional study on men who have sex with men (MSM) for the HIV prevention project was conducted to assess the prevalence of HIV infection–related behaviors among 551 MSM recruited in 2008–2009 and 1910 MSM in 2014–2018 for voluntary counseling and testing at a HIV clinic in Chiang Mai. Overall, the study found that the prevalence of HIV infection was significantly decreased from 12.9% (71/551) in the earlier study (2008–2009) to 8.2% (157/1910) in the recent study (2014–2018) ( p = 0.001). By comparison, in 2008–2009 and 2014–2018, there was no statistically significant difference in consistent condom use (39.0% [186/477] vs. 38.9% [591/1512], p = 0.969), while unprotected anal sex with casual partners significantly increased (44.5% [159/357] vs. 51.9% [645/1242], p = 0.014) and receptive anal sex significantly increased (37.7% [180/477] vs. 45.1% [860/1905], p = 0.004). However, previous HIV testing within 1 year increased significantly from 64.6% (197/305) to 74.7% (677/906, p = 0.001). In exploratory multivariate analysis, the factors associated with HIV infection included gay men, age below 20 years, being self-employed, being an employee, having only receptive anal sex, having both receptive/insertive anal sex, being a former substance user, using online dating, having a history of sexually transmitted infection symptoms, self-perception as being at high risk for HIV, last HIV testing >1 year, and never previously testing for HIV. The data represent the trend of health-seeking behavior improvements. The findings demonstrated the need for a novel sexual health service in an endemic setting and health promotion for online partner-seeking.
