BACKGROUND: Musculoskeletal disorders (MSDs) have been identified as a predisposing factor for lesser productivity, but no validated tool has been developed to assess them in the Sri- Lankan context. OBJECTIVE: To develop a validated tool to assess the neck and upper limb MSDs. METHODS: It comprises three components: item selections, item reduction using principal component analysis, and validation. A tentative self-administrated questionnaire was developed, translated, and pre-tested. Four important domains - neck, shoulder, elbow and wrist - were identified through principal component analysis. RESULTS: Prevalence of any MSDs was 38.1 and prevalence of neck, shoulder, elbow and wrist MSDs are 12.85, 13.71, 12, 13.71 respectively. Content and criterion validity of the tool was assessed. Separate ROC curves were produced and sensitivity and specificity of neck (83.1, 71.7), shoulder (97.6, 91.9), elbow (98.2, 87.2), and wrist (97.6, 94.9) was determined. Cronbach's Alpha and correlation coefficient was above 0.7. CONCLUSION: The tool has high sensitivity, specificity, internal consistency, and test re-test reliability. © 2016 - IOS Press and the authors. All rights reserved.

The effect of palm oil fiber-TiO2 ratio in the composite on the reduction of benzene, toluene, xylene and formaldehyde in the air is studied. The ratio was set at 1:0, 1:9 and 5:5. The combination of adsorption process by palm oil fiber and photooxidation of volatile organic compounds by titanium dioxide was revealed. The composite were prepared by using mechanical milling technique. The performance of the composite was characterized in terms of percentage of recovery of benzene, toluene and xylene (BTX) using GC/FID and formaldehyde concentration reduction using formaldehyde meter. The results of recovery of the BTX by palm oil fiber/titanium dioxide composite were more than 90%. The palm oil fiber/titanium dioxide composite has successfully reduced the concentration of formaldehyde by up to 66.7%. Therefore, the palm oil mesocarp fiber/titanium dioxide composite produced is able to reduce the concentration of volatile organic compounds. © 2016, Malaysian Society of Analytical Sciences.

Mining, crushing, grinding, sandblasting and construction are high-risk activities with regard to crystalline silica exposure, especially in developing countries. Respirable crystalline silica (quartz and cristobalite) inhaled from occupational sources has been reclassified as a human carcinogen in 1997 by the International Agency for Research on Cancer. However, the biological activity of crystalline silica has been found to be variable among different industries, and this has formed the basis for further in vivo/in vitro mechanistic research and epidemiologic studies. This study was conducted for genotoxicity evaluation in a population of workers (e.g. glass industry workers, sandblasters, and stone grinders) mainly exposed to crystalline silica in four different workplaces in Turkey. The micronucleus (MN) assay was applied both in peripheral blood lymphocytes (PBL) as a surrogate tissue and in nasal epithelial cells (NEC) as a target tissue of the respiratory tract. Our study revealed significantly higher MN frequencies in the workers (n = 50) versus the control group (n = 29) (P < 0.001) and indicated a significant effect of occupational exposure on MN induction in both of the tissues. For the NEC target tissue, the difference in MN frequencies between the workers and control group was 3-fold, whereas in peripheral tissue, it was 2-fold. Respirable dust and crystalline silica levels exceeding limit values and mineralogical/elemental dust composition of the dust of at least 70% SiO2 were used as markers of crystalline silica exposure in each of the workplaces. Moreover, 24% of the current workers were found to have early radiographical changes (profusion category of 1). In conclusion, although the PBL are not primary target cells for respiratory particulate toxicants, an evident increase in MN frequencies in this surrogate tissue was observed, alongside with a significant increase in NEC and may be an indicator of the accumulated genetic damage associated with crystalline silica exposure.

This study aims to determine the prevalence and associated factors of noise-induced hearing loss (NIHL) among vector control workers in the state of Negeri Sembilan, Malaysia. This was an analytical cross-sectional study conducted on 181 vector control workers who were working in district health offices in a state in Malaysia. Data were collected using a self-administered questionnaire and audiometry. Prevalence of NIHL was 26% among this group of workers. NIHL was significantly associated with the age-group of 40 years and older, length of service of 10 or more years, current occupational noise exposure, listening to loud music, history of firearms use, and history of mumps/measles infection. Following logistic regression, age of more than 40 years and noise exposure in current occupation were associated with NIHL with an odds ratio of 3.45 (95% confidence interval = 1.68-7.07) and 6.87 (95% confidence interval = 1.54-30.69), respectively, among this group of vector control workers. © 2012 APJPH.

A cross-section analytical study was conducted to evaluate the risk of pesticide exposure to those applying the Class II pesticides 2,4-D and paraquat in the paddy-growing areas of Kerian, Perak, Malaysia. It investigated the influence of weather on exposure as well as documented health problems commonly related to pesticide exposure. Potential inhalation and dermal exposure for 140 paddy farmers (handlers of pesticides) were assessed. Results showed that while temperature and humidity affected exposure, windspeed had the strongest impact on pesticide exposure via inhalation. However, the degree of exposure to both herbicides via inhalation was below the permissible exposure limits set by United States National Institute of Occupational Safety and Health (NIOSH). Dermal Exposure Assessment Method (DREAM) readings showed that dermal exposure with manual spraying ranged from moderate to high.Withmotorized sprayers, however, the level of dermal exposure ranged fromlow to moderate.Dermal exposure was significantly negatively correlated with the usage of protective clothing. Various types of deleterious health effects were detected among users of manual knapsack sprayers. Long-term spraying activities were positively correlated with increasing levels of the gamma-glutamyl transpeptidase (GGT) liver enzyme. The type of spraying equipment, usage of proper protective clothing and adherence to correct spraying practices were found to be the most important factors influencing the degree of pesticide exposure among those applying pesticides. © Taylor & Francis Group, LLC.

As a former government employee, I know that presidential transition periods can be stressful and filled with uncertainty. I’ve been trying to imagine what it’s like for federal employees who find themselves now part of the Trump Administration. Some of what I remember experiencing was simple frustration. We’d ask each other and our bosses, “Should I still work on this? Are we still doing that?” Often the answer was “just hold off on it for now.” But some of what you witness may have you saywonder “this seems like a really bad idea.”  Or it may make you question whether its legal or contrary to your agency’s mission. If that’s your situation and you want to share what you know with a trustworthy reporter, here’s an option: National Public Radio’s Investigations Correspondent Howard Berkes has setup two secure and encrypted means of communication for anyone inside federal or state agencies (or private companies) who want to contact a reporter.  They are: Private text messaging for iPhones and Android. Encrypted end-to-end. User needs to download free App at link above. Text Berkes at 8015989372.  Also works for encrypted phone calls. Encrypted email. Establish a ProtonMail account at the link above. Email Berkes at hberkes@protonmail.com If you use either of these methods, Howard Berkes suggests that you use a personal cell phone or computer. Berkes’ investigations have involved the Department of Labor, the Mine Safety and Health Administration, the Employee Benefits Security Administration, the Occupational Safety and Health Administration, the Office of Workers Compensation Programs, the Health Resources and Services Administration, the National Institute of Occupational Safety and Health, the Justice Department, NASA and the Environmental Protection Agency, as well as other federal and state agencies. When I worked at OSHA and MSHA, some of my personal mentors were colleagues who at one time or another confidentially shared information with reporters or staff on Capitol Hill. Sometimes it is the right thing to do.
