Workplace Assessment

Background: The high risk, fast-paced industrial expansion reflects unique health and safety challenges for occupational health and safety resulting in increasing incidence of various injuries and health morbidities. This warrants the assessment of morbidity profile and workplace assessment of the workers.Methods: A facility based cross sectional descriptive study was carried out among 305 workers of selected soap industries in Puducherry for a period of four months from September to December 2018. Workers were interviewed using a semi-structured questionnaire for their morbidity profile and work ability along with skin patch test and spirometry. Finally, workplace assessment was done.Results: Of 305 workers interviewed, eczema was reported in two workers and generalized pruritus in 4.9% of the workers. In patch test, 9 (34.6%) workers were sensitive to Paraphenylenediamine among 26 workers tested. Upper respiratory tract infection was reported in 17.3% and breathlessness in 4.6% of the employees. Spirometer was abnormal in 5.9% of the workers. Hypertension was diagnosed for the first time in 10.3% of the workers. Work ability index was good in 99.0% of the workers. The most common illness in the past six months was febrile illness. Workers who availed treatment from the private facility were 35.9%. Working environment was better in large-scale industries as compared to the small-scale industries.Conclusions: The morbidity of workers in selected soap industries were very less as majority of the workers was from the organized sectors with regular periodic examination. Hence further studies concentrating only on the unorganized small-scale industries are recommended.

The large- and small-scale vortical motions produced by ‘delta tabs’ in a two-stream shear layer have been studied experimentally. An increase in mixing was observed when the base of the triangular shaped tab was affixed to the trailing edge of the splitter plate and the apex was pitched at some angle with respect to the flow axis. Such an arrangement produced a pair of counter-rotating streamwise vortices. Hot-wire measurements detailed the velocity, time-averaged vorticity (Ωx) and small-scale turbulence features in the three-dimensional space downstream of the tabs. The small-scale structures, whose scale corresponds to that of the peak in the dissipation spectrum, were identified and counted using the peak-valley-counting technique. The optimal pitch angle, θ, for a single tab and the optimal spanwise spacing, S, for a multiple tab array were identified. Since the goal was to increase mixing, the optimal tab configuration was determined from two properties of the flow field: (i) the large-scale motions with the maximum Ωx, and (ii) the largest number of small-scale motions in a given time period. The peak streamwise vorticity magnitude [mid ]Ωx−max[mid ] was found to have a unique relationship with the tab pitch angle. Furthermore, for all cases examined, the overall small-scale population was found to correlate directly with [mid ]Ωx−max[mid ]. Both quantities peaked at θ≈±45°. It is interesting to note that the peak magnitude of the corresponding circulation in the cross-sectional plane occurred for θ≈±90°. For an array of tabs, the two quantities also depended on the tab spacing. An array of contiguous tabs acted as a solid deflector producing the weakest streamwise vortices and the least small-scale population. For the measurement range covered, the optimal spacing was found to be S≈1.5 tab widths.

OBJECTIVE: to evaluate the association between psychological demands, control over the work and the reduction of work ability of nursing professionals. METHOD: this cross-sectional study involved 498 nursing professionals of a university hospital in the State of Rio Grande do Sul, Brazil. Data collection was carried out in 2009 using the Brazilian versions of the Work Ability Index and Job Stress Scale, with logistic regression models used for the data analysis. RESULTS: the prevalence of 43.3% for reduced work ability and 29.7% for high-strain in the job (high psychological demand and low control) were observed. The chances for professionals presenting reduced work ability under high-strain were higher and significant when compared to those classified as being under low-strain, even after adjusting for potential confounders, except for age and gender. CONCLUSION: a high prevalence of reduced work ability was observed. This evidence indicates the need for investigation and detailed analysis of the psychosocial aspects of the professionals with regard to the health/disease process of nursing professionals.

Acute Pesticide Poisoning

ObjectiveTo estimate prevalence of acute pesticide poisoning (APP) and its association with neurobehavioural symptoms in Ethiopian pesticide applicators.MethodsWe performed a cross-sectional survey among 256 pesticide applicators from small-scale irrigated farms, a large-scale open farm and large-scale greenhouses. APP was ascertained using a modified WHO case definition, and neurobehavioural symptoms were collected with a standardised questionnaire (Q16). Exposure to pesticides was estimated using detailed exposure algorithms specifically developed for Ethiopian farms. Multiple logistic regression models were used to estimate risk of APP and its association with neurobehavioural symptoms.ResultsOverall APP prevalence was 16%. Working as an applicator in greenhouses was strongly associated with APP (OR 3.00, 95% CI 1.38 to 6.54). Estimated annual pesticide exposure was also associated with APP (OR 1.14, 95% CI 1.00 to 1.20). Longer duration of employment appeared to be negatively associated with APP. Having had an APP was strongly associated with reporting more neurobehavioural symptoms (OR 2.15, 95% CI 1.01 to 4.58) independent of cumulative pesticide exposure. Cumulative exposure to pesticides appeared to be associated with neurobehavioural symptoms among applicators without and with APP.ConclusionsWe showed a substantial prevalence of APP that differed between farming systems and was strongly associated with neurobehavioural symptoms. Intensity of exposure was also clearly associated with these symptoms. Reduction and control of occupational exposure to pesticides is urgently needed in Ethiopia.

Duration Of Unemployment

Background: This study investigated whether work ability is associated with the duration of unemployment, heart rate variability (HRV), and the level of physical activity. Methods: Thirty-four unemployed persons (mean 55.7 ± standard deviation 33.3 years, 22 female, 12 male, unemployed: range 1–22.5 years) participated in the cross-sectional study. The Work Ability Index (WAI) and International Physical Activity Questionnaire (IPAQ) were applied. Short-term (five minutes) resting HRV (Low Frequency (LF), High Frequency (HF), Total Power (TP)) was collected. Results: Work ability was positively associated with the HRV: LF (r = 0.383; p = 0.025), HF (r = 0.412; p = 0.015) and TP (r = 0.361; p = 0.036). The WAI showed a positive linear correlation with the amount of total physical activity (r = 0.461; p = 0.006) as well as with the amount of moderate to vigorous physical activity (r = 0.413; p = 0.015). No association between the WAI and the duration of unemployment occurred. Conclusions: the relation between self-perceived work ability, health-associated parameters, the HRV and the level of physical activity points out the relevance of health-care exercise and the need of stress-reducing interventions to improve perceived work ability. Our results point out the need for the further and more holistic development of healthcare for the unemployed.

Abstract Background: The work ability index (WAI) is one the most widely used instruments for measuring perceived work ability. However, very few studies have used this instrument in Iran. The present study is designed to assess effect of individual and work-related risk factors on the WAI in one dairy factory. Methods: This cross-sectional study was designed among 117 workers. Work ability was measured by the Persian versions of Work Ability Index (P-WAI). An author-developed measure was used to assess individual and work-related factors. All Statistical analyses were performed using IBM SPSS Statistics 21 (USA, SPSS Inc.). Results: The mean age of participants was 32.38 ± 7.3 and the Mean score of the WAI was 44.92 ± 5.56. According to the categorical classification of WAI score, 10.9, 35.6, and 53.5 % of participants had moderate, good and excellent work ability, respectively. The results of statistical analyses showed that mean WAI significantly differed with age (0.049), sleep quality (p= 0.035) and employment status (p= 0.014). Conclusion: To improve the workers’ work ability, intervention programs should focus on improving sleep quality and exercise. Also, we suggest that increasing job insecurity should be considered an important intervention in promoting worker’s work ability. Keywords: Work Ability Index (WAI), Sleep Quality, Job Insecurity

Translational Block

AbstractThe East Abbotsford translational block landslide failed suddenly on 8 August, 1979, after months and probably years of slowly accelerating movement. A displacement of about 50 m occurred on a bedding plane dipping 7°, about 30 m below ground surface, at or very near the contact between two formations.The complex graben formed around the head of the landslide is a small scale example of extensional (rift) tectonics. A wedge and prism model is developed to fit the geometry, and meet the constraints of preserving the cross-sectional area and stratal length of the beds involved and also to account for the sequential retrogressive failures of the trailing edge of the sliding block.Reconstruction of the failure sequence at the toe shows the compressional zone to be dominated by overthrusting on upward sloping surfaces or ramps, with subsidiary backthrusting and buckling.The energy expended in overthrusting, coupled with the decrease in mass (and hence driving force) resulting from the retrogressive spalling of the trailing edge of the slide block, indicates that the phase of rapid movement was accompanied by a sudden decrease in resistance on the failure surface for a movement of 50 m to have occurred.Both the rift and thrust structures associated with the landslide have large scale tectonic analogues.

Occupational Fatigue

Abstract Background Work ability and occupational fatigue are two critical topics in occupational health. We aimed to assess fatigue and the work ability and find their association in the workers of a large Iranian car company. Methods In this cross-sectional study, we enrolled the workers of SAIPA Automotive Corporation between April and September 2019. We used the Work Ability Index and SOFI-20 questionnaires to assess the work ability and occupational fatigue in the study population, respectively. Then the correlation between work ability index and its association with fatigue dimensions and general study variables were tested. Results From a total of 400 workers, we analyzed the data of 376 workers (mean age = 37.1 ± 5.6 years). The mean WAI was 38.01 ± 7.46. Workers with regular exercise training had higher WAI (P < 0.001). Workers in the press shop had a higher WAI as compared with those who worked in the painting shop or trim shop (P < 0.001). The work ability index had a moderate indirect correlation with all of the fatigue dimensions. There was a significant association between the work stations (P = 0.002) and WAI. As regards the fatigue dimensions, higher physical discomfort, lack of motivation and sleepiness were associated with a lower WAI (P = 0.048, P = 0.012 and P < 0.001 respectively). Conclusion In this study, we found a negative association between fatigue dimensions and the workability index.
