Exposure to dust in the work environment is a potential factor that can cause impaired pulmonary function. Concentration of dust in the air is one factor that affects the severity caused. Higher exposure to dust in the air, increase the risk of impaired pulmonary function. The objective of the research was to analyze the exposure to respirable cement dust and pulmonary function impairment of Finish Mill operators in PT. Semen Indonesia, Tuban Regency. This study used a cross-sectional study design, with the number of sample using purposive sampling method as many as 10 people. The level of inhaled semen dust is measured using a Personal Dust Sampler (PDS). The characteristics of workers are also seen include age, length of employment, smoking habits, use of personal protective equipment and respiratory complaints felt. The results of this study were 90% of operators with respirable dust levels > 3 mg/m3. The highest respirable dust content was 26,7151 mg/m3. The lowest respirable dust content was 1.4665 mg/m3. In addition, 22.2% of operators who have inhaled dust levels > 3 mg/m3 have impaired pulmonary function. Conclusions can be drawn pulmonary function impairment more experienced by operators aged 36 - 45 years, with a working period of more than 15 years. Smoking habits and respiratory history may be seen from operator respiratory complaints.Keywords: finish mill operators, pulmonary function test, respirable cement dust.

Abstract Informal-sector weavers using indigo-dyed cotton are occupationally exposed to respirable dust which may contain contaminants from chemicals used for pH adjustment in the natural indigo fermentation process. The major health problems associated with respirable dust induce pulmonary function impairment and respiratory disease. However, there have been few studies into the respiratory problems of informal-sector weavers in Thailand. This study investigated the link between occupational respirable dust exposure and pulmonary function among weavers using indigo-dyed cotton in Thailand. A cross-sectional study was conducted of 147 weavers located in Sakon Nakhon province. Respiratory dust (RD) samples were collected from the immediate breathing zone of all weavers. Lung function was measured using a portable spirometer operated by a trained physician and the spirometric results were examined by a pulmonologist before reporting. Most participants were female (98.6%) and the median reported interquartile age (IQR) was 58 (50–62.75) years. Average predicted values for FVC, FEV1 and FEV1/FVC were 92.9% (±20.7), 96.7% (±17.9) and 88.3% (±10.8). Of the respiratory function patterns of the 147 weavers, 20 (13.6%) were restrictive, 11 (7.5%) were obstructive and 1 (0.7%) was combined. The average RD concentration (mean ± SD) was 47.9 ± 28.3 μg/m3. Multivariate linear regression models showed an increase of 1 μg/m3 in RD exposure was associated with a 0.179% lower level of FEV1 (95% confidence interval (CI) -0.278 to -0.080) and a 0.068 % lower level of FEV1/FVC (95% CI -0.128 to -0.008). Our findings suggested that exposure to respirable dust might impair pulmonary function in informal-sector cotton weavers.

BACKGROUND: Limestone dust is produced by limestone mining activities, one of them is PM2.5. Exposure of PM2.5 can cause lung function impairment. AIM: The purpose of this study was to determine the correlation exposure of PM2.5 with lung function impairment in workers. METHODS: This study used a cross-sectional study with total sampling technique of 30 workers. The instruments in this study used questionnaires for interviews, Dusttrak II TSI to measure PM2.5 concentration and spirometry to measure lung function. RESULTS: Based on the results of the study, the highest PM2.5 concentration values were 987 μg/m3 and the lowest were 14 μg/m3. The results of the analysis using Chi-square obtained a correlation between the use of personal protective equipment with lung function impairment (p = 0.000). Furthermore, the results using the Fisher’s exact test, there was a correlation between PM2.5 concentration and pulmonary function impairment (p = 0.002) and years of work with pulmonary function impairment (p = 0.000). CONCLUSION: Further research is needed using environmental health risk analysis to estimates based on intake.

Abstract Background Post-discharge immunity and its correlation with clinical features among patients recovered from COVID-19 are poorly described. This prospective cross-sectional study explored the inflammatory profiles and clinical recovery of COVID-19 patients at 3 months post-discharge. Methods COVID-19 patients discharged from four hospitals in Wuhan, recovered asymptomatic patients (APs) from an isolation hotel, and uninfected healthy controls (HCs) were recruited. Viral nucleic acid and antibody detection, laboratory examination, computed tomography, pulmonary function assessment, multiplex cytokine assay, and flow cytometry were performed. Results The 72 age-, sex- and body mass index-matched participants included 19 severe/critical patients (SPs), 20 mild/moderate patients (MPs), 16 APs, and 17 HCs. At 3 months after discharge, levels of pro-inflammatory cytokines and factors related to vascular injury/repair in recovered COVID-19 patients had not returned to those of the HCs, especially among recovered SPs compared to recovered MPs and APs. These cytokines were significantly correlated with impaired pulmonary function and chest CT abnormalities. However, levels of immune cells had returned to nearly normal levels and were not significantly correlated with abnormal clinical features. Conclusion Vascular injury, inflammation, and chemotaxis persisted in COVID-19 patients and were correlated with abnormal clinical features 3 months after discharge, especially in recovered SPs.

ABSTRACT CONTEXT AND OBJECTIVE: The combined effect of obesity and asthma may lead to significant impairment of quality of life (QOL). The aim here was to evaluate the prevalence of asthma among obese individuals, characterize the severity of impairment of quality of life and measure its relationship with pulmonary function. DESIGN AND SETTING: Observational cross-sectional study in public university hospital. METHODS: Morbidly obese individuals (body mass index > 40 kg/m2) seen in a bariatric surgery outpatient clinic and diagnosed with asthma, were included. Anthropometric data were collected, the Standardized Asthma Quality of Life Questionnaire (AQLQ(S)) was applied and spirometry was performed. The subjects were divided into two groups based on the median of the score in the questionnaire (worse < 4 and better > 4) and were compared regarding anthropometric data and pulmonary function. RESULTS: Among the 4791 individuals evaluated, 219 were asthmatic; the prevalence of asthma was 4.57%. Of these, 91 individuals were called to start multidisciplinary follow-up during the study period, of whom 82 answered the questionnaire. The median score in the AQLQ(S) was 3.96 points and, thus, the individuals were classified as having moderate impairment of their overall QOL. When divided according to better or worse QOL, there was a statistically difference in forced expiratory flow (FEF) 25-75%, with higher values in the better QOL group. CONCLUSION: The prevalence of asthma was 4.57% and QOL was impaired among the asthmatic obese individuals. The worst QOL domain related to environmental stimuli and the best QOL domain to limitations of the activities. Worse QOL was correlated with poorer values for FEF 25-75%.

AbstractObjectiveA limited but growing body of evidence supports a significant role of antioxidant and anti-inflammatory micronutrients in pulmonary health. We investigated the associations of dietary and supplemental intakes of vitamins A, C, E and D, Se and n-3 PUFA with pulmonary function in a population-based study.DesignPopulation-based, cross-sectional study and data analysis of fruits and vegetables, dairy products and fish, vitamins A, C, E and D, Se and n-3 PUFA supplemental intakes, pulmonary risk factors and spirometry.SubjectsChinese older adults (n 2478) aged 55 years and above in the Singapore Longitudinal Ageing Studies.ResultsIn multiple regression models that controlled simultaneously for gender, age, height, smoking, occupational exposure and history of asthma/chronic obstructive pulmonary disease, BMI, physical activity, and in the presence of other nutrient variables, daily supplementary vitamins A/C/E (b = 0·044, se = 0·022, P = 0·04), dietary fish intake at least thrice weekly (b = 0·058, se = 0·016, P < 0·0001) and daily supplementary n-3 PUFA (b = 0·068, se = 0·032, P = 0·034) were individually associated with forced expiratory volume in the first second. Supplemental n-3 PUFA was also positively associated with forced vital capacity (b = 0·091, se = 0·045, P = 0·045). No significant association with daily dairy product intake, vitamin D or Se supplements was observed.ConclusionsThe findings support the roles of antioxidant vitamins and n-3 PUFA in the pulmonary health of older persons.

The cooking process may emit toxic compounds and airway irritants from both the fuel combustion and cooking fumes which is harmful to the respiratory health among the restaurant workers. A cross-sectional study of 243 restaurant workers from the selected restaurants in Sungai Long, Malaysia was conducted. The standardized British Medical Research Council questionnaire on Respiratory Symptoms (1986) was used during the interview to access the symptoms and the spirometry test was performed to evaluate the pulmonary functions of the participants. The data of socio-demography and occupational characteristics were also collected. The most complaint respiratory symptoms by the restaurant workers were breathlessness, which accounted for 33.7%, followed by wheezing (14%). The mean values of all pulmonary function tests (PFT) of the restaurant workers were within the normal range (>80%), except for the Peak Expiratory Flow (PEF) (79.09%). The results of the bivariate statistical analysis, Chi-square, ANOVA and t-test, showed the determining factors of the respiratory health among the workers were workers’ age and gender in addition to the working duration and the ethnicity. The restaurant workers in Sungai Long were at risk of developing respiratory symptoms and lower pulmonary function values due to prolonged exposure to cooking fumes. Emphasis should be given to the safety and health of restaurant workers and health education should be provided to the restaurant workers and owners. Strategies to increase notification of such occurrences among these workers should be looked into by related agencies in the country.

Introduction: Spirometry is used as a screening method for occupational lung diseases. Dental laboratory workers are exposed to solvent vapors, toxic gases, and dust from metal alloys, acrylics, and gypsum. This study aimed to investigate the spirometric function of lung function in dental staff in Yazd. Materials and Methods: This descriptive cross-sectional study was performed on 37 technicians of dental laboratories in Yazd in the three months of spring 2017. To evaluate respiratory problems and their pulmonary function, standard respiratory and spirometry questionnaires according to ATS / ESR guidelines were used, respectively. Data were analyzed by SPSS software version 18 using Mann-Whitney U, Chi-square, and Student's T-test. Results: Mean age of participants was 35.59±1.13. 54% of participants had no respiratory symptoms. The most common respiratory complain were dry and exudative cough. The work field was the only influential factor in FVC%. Age and work experience, and exercise no significant effect on respiratory parameters. Overall spirometry parameters were in the normal pattern range, and only 5% of participants showed a mild restrictive pattern. Conclusion: Spirometric pulmonary function of Yazd'dental laboratory technicians was in the normal range, and possibly working in the dental laboratory did not have a significant effect on the pulmonary Function of technicians based on spirometric indices.

IntroductionThe workplace remains a significant source of secondhand smoke (SHS) exposure. This pollutant is known to be associated with respiratory and cardiovascular problems, but its effects on specific pulmonary function parameters remain largely unexplored. The objectives of this study were to measure SHS exposure among non-smoking employees of bar and restaurants in Santiago, Chile and to evaluate the effects of such exposure on pulmonary function.MethodsCross-sectional design. The study sample included non-smoking workers from 57 restaurants and bars in Santiago, Chile. The outcome variable was pulmonary function and the exposure variables were urine cotinine concentration, a biomarker for current SHS exposure, and years of SHS exposure in the workplace as proxy of chronic exposure. Personal and occupational variables were also recorded. Data analysis was performed using linear regression models adjusted by confounders.ResultsThe median age of the workers was 35 years and the median employment duration at the analysed venues was 1 year. Workers in smoking facilities reported greater SHS exposure (36 hours per week) than workers in smoke-free locations (4 hours per week). Urine cotinine levels were inversely correlated with forced vital capacity, but the finding was not statistically significant (β=−0.0002; 95% CI −0.007 to 0.006). Years of exposure to SHS showed to be significantly associated with forced expiratory flow25/75(β=−0.006; 95% CI −0.010 to −0.0004).ConclusionThese findings suggest that cumulative exposure to SHS at work may contribute to deterioration of pulmonary function in non-smoking employees.
