We conducted a systematic review and meta-analysis to investigate cancer and mortality in coal mine workers We searched in Ovid Medline, PubMed, Embase and Web of Science databases using keywords and text words related to coal mines, cancer and mortality and identified 36 full-text articles using predefined inclusion criteria. Each study’s quality was assessed using the Newcastle-Ottawa Scale. We performed random-effect meta-analyses including 21 of the identified articles evaluating cancer and/or mortality of coal mine workers. The meta-analysis showed an increased risk of all-cause mortality (SMR 1.14, 95% CI 1.00 to 1.30) and mortality from non-malignant respiratory disease (NMRD) (3.59, 95% CI 3.00 to 4.30) in cohorts with coal workers’ pneumoconiosis (CWP).

Our study aimed to examine the extent and associated factors to psychological distress, the level of fear of COVID-19, and coping strategies amongst a diverse range of community people in multi-country settings. Methods: A cross-sectional study across 17 countries was conducted. Psychological distress (based on the Kessler Psychological Distress Scale) was categorized into low and moderate to very high, fear of COVID-19 (based on the Fear of COVID-19 Scale) was categorized into low and high, and coping (based on the Brief Resilient Coping Scale) was categorized into low and medium to high. For country-wise comparisons, we selected the reference country based on the lowest prevalence of each outcome and examined the status for other countries. Multivariate analyses were conducted to adjust potential confounders including in-country variations; adjusted odds ratio (AOR) and 95% confidence intervals (CIs) were reported. Findings: A total of 8559 people participated in this study. Mean age (±SD) was 33 (±13) years and two-thirds (64%) were females. More than one-third (40%) self-identified as frontline or essential service workers. More than two-thirds (69%) experienced moderate to very high levels of psychological distress, which was 46% in Thailand and 91% in Egypt. A quarter (24%) had high levels of fear of COVID-19, which was as low as 9% in Libya and as high as 38% in Bangladesh. More than half (57%) exhibited medium to high resilient coping; the lowest prevalence (3%) was reported in Australia and the highest (72%) in Syria. Being female (AOR 1.31 [95% CIs 1.09-1.57]), perceived distress due to change of employment status (AOR 1.56 [1.29-1.90]), being affected by the change of financial situation, comorbidity with mental health conditions (AOR 3.02 [1.20-7.60]), unsure contact with COVID-19 patient, and use of healthcare services in the last six months were associated with moderate to very high levels of psychological distress. Doctors had higher psychological distress (AOR 1.43 [1.04-1.97]), but low levels of fear of COVID-19 (AOR 0.55 [0.41-0.76]); nurses had medium to high resilient coping (AOR 1.30 [1.03-1.65]). Participants from 10 countries (Hong Kong, Oman, Libya, Kuwait, Saudi Arabia, UAE, Jordan, Syria, Palestine and Egypt) demonstrated significantly higher psychological stress compared to the participants from Thailand. Participants from four countries (Oman, Indonesia, Hong Kong and Pakistan) exhibited higher levels of fear of COVID-19 compared to those from Libya. Participants from 12 countries (Jordan, Egypt, Saudi Arabia, Kuwait, Hong Kong, UAE, Palestine, Thailand, Oman, Nepal, Indonesia and Syria) demonstrated statistically significant medium to high resilience coping compared to those from Australia. Interpretation: Females and people with existing mental health issues were the most vulnerable groups of populations for adverse psychological impact of COVID-19 pandemic across 17 countries. While these two groups had ongoing challenges in a COVID-free world, the pandemic worsened their wellbeing. There is an urgent need to prioritise their needs. Adequate medical and social support along with specific health promotion policies should be considered within the strategic response to the ongoing pandemic and future crises. Funding Information: None. Declaration of Interests: We declare no competing interests. Ethics Approval Statement: Ethics approval was obtained from the Human Research Ethics Committee from each participating country. The survey was voluntary in nature and it was clarified in the PLIS, so that participants got the opportunity to have informed decision to participate in the study.

Two researchers independently searched databases for published articles using predefined inclusion criteria. Study quality was assessed, and results pooled for COPD and chronic bronchitis for exposure to biological dust, mineral dust, and gases/fumes using a fixed and random effect model. Five studies met predetermined inclusion criteria. The meta-analysis showed low exposure to mineral dust, and high exposure to gases/fumes were associated with an increased risk of COPD. We also found significantly increased the risk of chronic bronchitis for low and high exposure to biological dust and mineral dust. Expert commentary: The relationship between occupational exposure assessed by the JEM and the risk of COPD and chronic bronchitis shows significant association with occupational exposure. However, the heterogeneity of the meta-analyses suggests more wide population-based studies with older age groups and longitudinal phenotype assessment of COPD to clarify the role of occupational exposure to COPD risk.

In this study, we aimed to determine the patient and health-system level factors associated with all-cause and unplanned hospital readmission within 90 days after acute stroke or transient ischemic attack (TIA) in Australia. Methods— We used person-level linkages between data from the Australian Stroke Clinical Registry (2009–2013), hospital admissions data and national death registrations from 4 Australian states. Time to first readmission (all-cause or unplanned) for discharged patients was examined within 30, 90, and 365 days, using competing risks regression to account for deaths postdischarge. Covariates included age, stroke severity (ability to walk on admission), stroke type, admissions before stroke/TIA and the Charlson Comorbidity Index (derived from International Statistical Classification of Diseases and Related Health Problems...

Methods We included 1335 participants from the 2002-2008 follow-up of the Tasmanian Longitudinal Health Study. Ever-exposure and cumulative exposure-unit (EU) years were calculated using the ALOHA plus job exposure matrix (JEM). Fixed AO was defined as post-bronchodilator forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) <0.7 and FEV 1/FVC<lower limit of normal. Diffusing capacity of the lung for carbon monoxide (DLCO) was combined with FEV 1/FVC<0.7 to define fixed AO plus low DLco. Multinomial regressions were used to estimate associations adjusting for possible confounders. Results Ever-exposure to metals was associated with fixed AO [relative risk (RR) 1.71, 95% CI 1.03-2.85] and fixed AO lower limit of normal (RR 1.67, 95% CI 1.00-2.78). Women had lower cumulative EU ye...

Establishing this link using postbronchodilator is critical, because occupational exposures are a modifiable risk factor for COPD. To investigate the associations between occupational exposures and fixed airflow obstruction using postbronchodilator spirometry. One thousand three hundred and thirty-five participants were included from 2002 to 2008 follow-up of the Tasmanian Longitudinal Health Study (TAHS). Spirometry was performed and lifetime work history calendars were used to collect occupational history. ALOHA plus Job Exposure Matrix was used to assign occupational exposure, and defined as ever exposed and cumulative exposure unit (EU)-years. Fixed airflow obstruction was defined by postbronchodilator FEV1/FVC <0.7 and the lower limit of normal (LLN). Multinomi...

Most of the studies have been carried out among school children and very few among adults in Bangladesh. An investigation was carried out among 308 adult to know the prevalence of dental caries in rural area of Bangladesh. The examination was carried out under adequate light and dental caries was diagnosed according to WHO criteria 1983. The prevalence of untreated dental caries was found 58.1% in women and the figure for men was 41.9%, which was statistically significant (p-value<0.05).A statistical significant association was found between dental caries and brushing time (p-value<0.05), dental caries and brushing in a day (p-value<0.05).Findings from multivariable logistic regression model was also revealed this relationship. This study concludes that the prevalence of dental caries among...

Covariates included age, stroke severity (ability to walk on admission), stroke type, admissions before stroke/TIA and the Charlson Comorbidity Index (derived from International Statistical Classification of Diseases and Related Health Problems...

Methods We included 1335 participants from the 2002-2008 follow-up of the Tasmanian Longitudinal Health Study. Ever-exposure and cumulative exposure-unit (EU) years were calculated using the ALOHA plus job exposure matrix (JEM). Fixed AO was defined as post-bronchodilator forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) <0.7 and FEV 1/FVC<lower limit of normal. Diffusing capacity of the lung for carbon monoxide (DLCO) was combined with FEV 1/FVC<0.7 to define fixed AO plus low DLco. Multinomial regressions were used to estimate associations adjusting for possible confounders. Results Ever-exposure to metals was associated with fixed AO [relative risk (RR) 1.71, 95% CI 1.03-2.85] and fixed AO lower limit of normal (RR 1.67, 95% CI 1.00-2.78). Women had lower cumulative EU ye...

Establishing this link using postbronchodilator is critical, because occupational exposures are a modifiable risk factor for COPD. To investigate the associations between occupational exposures and fixed airflow obstruction using postbronchodilator spirometry. One thousand three hundred and thirty-five participants were included from 2002 to 2008 follow-up of the Tasmanian Longitudinal Health Study (TAHS). Spirometry was performed and lifetime work history calendars were used to collect occupational history. ALOHA plus Job Exposure Matrix was used to assign occupational exposure, and defined as ever exposed and cumulative exposure unit (EU)-years. Fixed airflow obstruction was defined by postbronchodilator FEV1/FVC <0.7 and the lower limit of normal (LLN). Multinomi...

Most of the studies have been carried out among school children and very few among adults in Bangladesh. An investigation was carried out among 308 adult to know the prevalence of dental caries in rural area of Bangladesh. The examination was carried out under adequate light and dental caries was diagnosed according to WHO criteria 1983. The prevalence of untreated dental caries was found 58.1% in women and the figure for men was 41.9%, which was statistically significant (p-value<0.05).A statistical significant association was found between dental caries and brushing time (p-value<0.05), dental caries and brushing in a day (p-value<0.05).Findings from multivariable logistic regression model was also revealed this relationship. This study concludes that the prevalence of dental caries among...
