Photokeratoconjunctivitis Symptoms among Informal Welding Operators in North Samarinda, Indonesia

AbstractInformal sector has been contributing to the national economy but occupational health and safety practices in the sector has not been satisfactory. One of the informal sector which are found in North Samarinda is informal welding workshop, with dominant hazards is exposure to ultraviolet rays that can cause photokeratoconjunctivitis. The Objective of this study was to investigate the symptoms of photokeratoconjunctivitis and related factors among informal welding operator in North Samarinda. A cross-sectional study was conducted on 40 respondents. Research was conducted in March until November 2016. Data collection using ultraviolet detector meter, clamps meter, and questionnaire. Data analysis using chi-square, Pearson’s correlation product moment and multiple linear regression. 50% of respondents have photokeratoconjunctivitis symptoms. Personal protective equipment (PPE) (p=0.004), UV exposure duration (0.056), knowledge of health and safety (p=0.055) and number of working days (p=0.001) were associated with photokeratoconjunctivitis symptoms. Work location (p=0.244), level of education (p=0.680), age (0.167), intensity of UV radiation (p=0.206) and strength of welding current (p=0.085) were not related to photokeratoconjunctivitis symptoms. In conclusions, photokeratoconjunctivitis symptoms is influenced by the use of PPE, UV exposure duration, knowledge of health and safety, and number of working days. The most influential factor to the appearance of photokeratoconjunctivitis (β=0.32) is duration of UV exposure.AbstrakSektor informal telah berkontribusi terhadap perekonomian nasional, namun praktik kesehatan dan keselamatan kerja pada sektor ini masih belum memuaskan. Salah satu usaha sektor informal yang banyak dijumpai di Samarinda Utara adalah usaha pengelasan dengan potensi bahaya utama paparan sinar ultraviolet yang dapat menyebabkan photokeratoconjunctivitis. Penelitian ini bertujuan menginvestigasi kejadian photokeratoconjunctivitis dan faktor yang memengaruhinya pada operator las informal di Kelurahan Samarinda Utara. Penelitian cross-sectional telah dilakukan terhadap 40 responden pada bulan Maret sampai November 2016. Pengumpulan data menggunakan UV detector meter, clamp meter, dan kuesioner.

Abstract Background There are fundamental and rapid changes in body shape during pregnancy, some of which persist for an extended time after delivery and may cause dissatisfaction with body shape. Therefore, we conducted this study to determine predictors of body dissatisfaction at six months postpartum based on demographic and fertility factors. Methods This cross-sectional study was conducted on 300 women who referred to seven health centers affiliated with Iran University of Medical Sciences, Tehran, Iran. The sampling was multistage and we collected data from a demographic and fertility questionnaire and Cooper’s Body Shape Questionnaire (BSQ-34). The independent t-test, Mann-Whitney U test, chi-square test, one-way ANOVA, Kruskal-Wallis, Pearson correlation coefficient, and multiple linear regression were used for data analysis. The level of significance was set at P < 0.05. Results The mean age of participating women was 29.77 (standard deviation: 5.9) years. Body dissatisfaction had a statistically significant association with variables such as body mass index (BMI) at six months postpartum, gestational age, the receipt of information about body shape, spouse’s views on the shape of a woman’s body, and mode of delivery. These variables predicted 34% of body dissatisfaction based on multiple linear regression. Conclusion Postpartum body dissatisfaction is related to a several variables. Paying attention to these variables will help to plan and improve postpartum counseling and educational programs.

BACKGROUND: Low Health Literacy (HL) and Nutrition Literacy (NL) are associated with serious negative health outcomes. OBJECTIVES: The aim of this study was to investigate certain lifestyle factors and obesity, in relation to HL and NL. METHODS: This cross-sectional study was conducted in the urban area of the Attica region, in Greece. The sample consisted of 1281 individuals, aged ≥18 years. HL, NL sociodemographic characteristics and lifestyle factors (physical activity, smoking status, alcohol consumption,) were assessed. Mann-Whitney U, the Kruskall Wallis, Pearson chi-square tests and multiple linear regression models were used. RESULTS: Linear regression analysis has shown that smoking, alcohol consumption and physical activity, were associated with HL levels (–1.573 points for ex-smokers in comparison to smokers, p = 0.035, –1.349 points for alcohol consumers in comparison to non-consumers, p = 0.006 and 1.544 points for physically active individuals to non-active, p = 0.001). With respect to NL levels, it was also not associated with any of these factors. Obesity was not associated with HL and NL levels. CONCLUSIONS: Certain lifestyle factors, including physical activity, are predicting factors of HL levels, in Greek adults. The results contribute to the understanding of the relationship between lifestyle factors and HL and should be taken into account when HL policies are designed.

BACKGROUND: The implementation of the electronic judicial process (PJe) in recent years is associated with an increase in workload and stricter control through productivity targets in the Brazilian labor judiciary. OBJECTIVES: To evaluate the relations between musculoskeletal symptoms, psychosocial factors and work ability in civil servants of a labor justice body in the context of the PJe. METHODS: A cross-sectional exploratory study with a quantitative approach involving 449 workers. Sociodemographic, occupational and related data were collected through questionnaires validated in the Brazilian context. Data analysis was conducted by descriptive and inferential statistics: Mann-Whitney test, Spearman’s correlation coefficient and multiple linear regression. RESULTS: There was a correlation between musculoskeletal symptoms and psychosocial factors (p < 0.05), as well as between both musculoskeletal symptoms and psychosocial factors with reduced work ability (p < 0.05). The multiple linear regression model pointed to the female gender and the dimensions “demands”, “control” and “peer support” as related to the musculoskeletal symptoms. CONCLUSION: We highlight the importance of a broader approach, involving psychosocial factors in preventive actions related to musculoskeletal disorders considering the important relationship with work ability.

AbstractKnowledge about modifiable determinants of daily physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) is crucial to design effective PA interventions. The present study aimed to determine the contribution of quadriceps strength, power and endurance to daily PA in COPD. Additionally, for quadriceps endurance, we also aimed to determine to what extent the association varies according to the mode of movement (isotonic, isometric, or isokinetic). Using a multicentre cross-sectional trial design we determined the contribution of quadriceps function to daily PA (steps, sedentary time and time spent doing moderate-to-very-vigorous physical activity [MVPA]) using bivariate and partial Pearson correlation analysis (r) and multiple linear regression models (ΔR2). Pre-determined controlling factors were sex, age, body mass index (BMI), COPD-assessment test, forced expiratory volume in one second in percent of the predicted value (FEV1pred), and distance walked on the 6-minute walk test. Eighty-one patients with COPD (mean ± SD: age 67 ± 8 years, FEV1pred 57 ± 19%, daily steps 4968 ± 3319, daily sedentary time 1016 ± 305 min, and MVPA time 83 ± 45 min) were included. Small to moderate bivariate correlations (r = .225 to .452, p < .05) were found between quadriceps function and measures of PA. The best multiple linear regression models explained 38–49% of the variance in the data. Isotonic endurance was the only muscle contributor that improved all PA models; daily steps (ΔR2 = .04 [relative improvement 13%] p = .026), daily sedentary time (ΔR2 = .07 [23%], p = .005) and MVPA-minutes (ΔR2 = .08 [20%], p = .001). Isotonic endurance was also independently associated with most PA variables, even when controlling for strength, power or isometric-isokinetic endurance properties of the muscle (r = .246 to .384, p < .05). In contrast, neither strength, power, isometric-or isokinetic endurance properties of the muscle was independently associated with PA measures when controlling for isotonic endurance (r = .037 to .219, p > .05). To conclude, strength, power, and endurance properties of the quadriceps were low to moderately associated with PA in patients with COPD. Isotonic quadriceps endurance was the only quadriceps property that was independently associated with the different measures of PA after controlling for a basic set of known determinants of PA, quadriceps strength or power, or isometric or isokinetic quadriceps endurance. Future longitudinal studies should investigate its potential as a modifiable determinant of PA.

Abstract Aim The aim of this study is to investigate the prevalence of asymptomatic hyperuricemia in Qatar and to examine its association with changes in markers of dyslipidemia, prediabetes and subclinical inflammation. Methods A cross-sectional study of young adult participants aged 18 - 40 years old devoid of comorbidities collected between 2012 and 2017. Exposure was defined as uric acid level, and outcomes were defined as levels of different blood markers. De-identified data were collected from Qatar Biobank. T-tests, correlation tests and multiple linear regression were all used to investigate the effects of hyperuricemia on blood markers. Statistical analyses were conducted using STATA 16. Results The prevalence of asymptomatic hyperuricemia is 21.2% among young adults in Qatar. Differences between hyperuricemic and normouricemic groups were observed using multiple linear regression analysis and found to be statistically and clinically significant after adjusting for age, gender, BMI, smoking and exercise. Significant associations were found between uric acid level and HDL-c p = 0.019 (correlation coefficient -0.07 (95% CI [-0.14, -0.01]); c-peptide p = 0.018 (correlation coefficient 0.38 (95% CI [0.06, 0.69]) and monocyte to HDL ratio (MHR) p = 0.026 (correlation coefficient 0.47 (95% CI [0.06, 0.89]). Conclusions Asymptomatic hyperuricemia is prevalent among young adults and associated with markers of prediabetes, dyslipidemia, and subclinical inflammation.

INTRODUCTION: Research has proven that music plays an important role in alleviating fear and anxiety among patients.AIM: To assess the effect of audio analgesia in pre-teen children aged 8-12 years undergoing dental restorations. MATERIALS AND METHOD: Data was collected using a pre-tested and pre-validated proforma filled by the child prior to start of the treatment by circling the number corresponding to the expected pain during the procedure [Ranged 0 (No pain) -10 (Maximum pain)]. Children who reported their expected pain above 5, were enrolled in group 1 (The ones receiving audio analgesia) while the remaining were assigned group 2 (controls). Children in group 1 were asked to put on their favourite song using noise cancellation headphones and the procedure was commenced. After completion of the treatment, the VAS scale was re-introduced and the children were asked to re-circle the actual pain experienced during the procedure. Data was analyzed using SPSS version 20.0 using the chi-squared test and Pearson’s correlation coefficient. A significant value was obtained when p was≤ 0.05. RESULTS: Of the total 80 children enrolled in the present study, there were an equal number of males and females (40 each). It was observed that 70.3% of children in group 1 had an increased pain tolerance as compared to only 37.2% of children in the control group(p=0.01). Pearson’s Correlation revealed a positive and linear association (r: +0.721) and a significant relationship (p = 0.03) between both groups. CONCLUSION: Audio analgesia has been proven to a promising alternative to distract the patient from the anxiety faced in the dental setting and is recommended for nervous and anxious patients.
