Global and regional burden of disease and injury in 2016 arising from occupational exposures: a systematic analysis for the Global Burden of Disease Study 2016
Objectives This study provides an overview of the influence of occupational risk factors on the global burden of disease as estimated by the occupational component of the Global Burden of Disease (GBD) 2016 study.
Methods The GBD 2016 study estimated the burden in terms of deaths and disability-adjusted life years (DALYs) arising from the effects of occupational risk factors (carcinogens; asthmagens; particulate matter, gases and fumes (PMGF); secondhand smoke (SHS); noise; ergonomic risk factors for low back pain; risk factors for injury). A population attributable fraction (PAF) approach was used for most risk factors.
Results In 2016, globally, an estimated 1.53 (95% uncertainty interval 1.39–1.68) million deaths and 76.1 (66.3–86.3) million DALYs were attributable to the included occupational risk factors, accounting for 2.8% of deaths and 3.2% of DALYs from all causes. Most deaths were attributable to PMGF, carcinogens (particularly asbestos), injury risk factors and SHS. Most DALYs were attributable to injury risk factors and ergonomic exposures. Men and persons 55 years or older were most affected. PAFs ranged from 26.8% for low back pain from ergonomic risk factors and 19.6% for hearing loss from noise to 3.4% for carcinogens. DALYs per capita were highest in Oceania, Southeast Asia and Central sub-Saharan Africa. On a per capita basis, between 1990 and 2016 there was an overall decrease of about 31% in deaths and 25% in DALYs.
Conclusions Occupational exposures continue to cause an important health burden worldwide, justifying the need for ongoing prevention and control initiatives
Global and regional burden of cancer in 2016 arising from occupational exposure to selected carcinogens: a systematic analysis for the Global Burden of Disease Study 2016
Objectives This study provides a detailed analysis of the global and regional burden of cancer due to occupational carcinogens from the Global Burden of Disease 2016 study.
Methods The burden of cancer due to 14 International Agency for Research on Cancer Group 1 occupational carcinogens was estimated using the population attributable fraction, based on past population exposure prevalence and relative risks from the literature. The results were used to calculate attributable deaths and disability-adjusted life years (DALYs).
Results There were an estimated 349 000 (95% Uncertainty Interval 269 000 to 427 000) deaths and 7.2 (5.8 to 8.6) million DALYs in 2016 due to exposure to the included occupational carcinogens—3.9% (3.2% to 4.6%) of all cancer deaths and 3.4% (2.7% to 4.0%) of all cancer DALYs; 79% of deaths were of males and 88% were of people aged 55 –79 years. Lung cancer accounted for 86% of the deaths, mesothelioma for 7.9% and laryngeal cancer for 2.1%. Asbestos was responsible for the largest number of deaths due to occupational carcinogens (63%); other important risk factors were secondhand smoke (14%), silica (14%) and diesel engine exhaust (5%). The highest mortality rates were in high-income regions, largely due to asbestos-related cancers, whereas in other regions cancer deaths from secondhand smoke, silica and diesel engine exhaust were more prominent. From 1990 to 2016, there was a decrease in the rate for deaths (−10%) and DALYs (−15%) due to exposure to occupational carcinogens.
Conclusions Work-related carcinogens are responsible for considerable disease burden worldwide. The results provide guidance for prevention and control initiatives
Policy-maker attitudes to the ageing of the HIV cohort in Botswana
Background: The roll out of antiretroviral therapy in Botswana, as in many countries with near universal access to treatment, has transformed HIV into a complex yet manageable chronic condition and has led to the emergence of a population aging with HIV. Although there has been some realization of this development at international level, no clear defined intervention strategy has been established in many highly affected countries. Therefore we explored attitudes of policy-makers and service providers towards HIV among older adults (50 years or older) in Botswana.Methods: We conducted qualitative face-to-face interviews with 15 consenting personnel from the Ministry of Health, medical practitioners and non-governmental organizations involved in the administration of medical services, planning, strategies and policies that govern social, physical and medical intervention aimed at people living with HIV and health in general. The Shiffman and Smith Framework of how health issues become a priority was used as a guide for our analysis.Results: Amidst an HIV prevalence of 25% among those aged 50–64 years, the respondents passively recognized the predicament posed by a population aging with HIV but exhibited a lack of comprehension and acknowledgement of the extent of the issue. An underlying persistent ageist stigma regarding sexual behaviour existed among a number of interviewees. Respondents also noted the lack of defined geriatric care within the provision of the national health care system. There seemed, however, to be a debate among the policy strategists and care providers as to whether the appropriate response should be specifically towards older adults living with HIV or rather to improve health services for older adults more generally. Respondents acknowledged that health systems in Botswana are still configured for individual diseases rather than coexisting chronic diseases even though it has become increasingly common for patients, particularly the aged, to have two or more medical conditions at the same time.Conclusions: HIV among older adults remains a low priority among policy-makers in Botswana but is at least now on the agenda. Action will require more concerted efforts to recognize HIV as a lifelong infection and putting greater emphasis on targeted care for older adults, focussing on multimorbidity.Keywords: ageing population, older adults, PLWH, HIV polic

Colon and rectal cancer incidence and water trihalomethane concentrations in New South Wales, Australia
BACKGROUND There is evidence, although inconsistent, that long term exposure to disinfection by products (DBPs) increases the risk of bowel cancer. No study has been conducted in Australia to examine this association and due to difference in the methods of disinfection the risk can vary across geographical regions and. This study was conducted to analyse the association of trihalomethanes (THMs) in water with colon and rectal cancer in NSW Australia. METHODS Average yearly concentrations of total and individual species of THMs were obtained for 50 local government areas (LGAs). Indirectly-standardized incidence rates of colon and rectal cancers in LGAs for the period 1995 to 2001 were regressed against mean THM concentrations lagged five years, adjusting for socioeconomic status, high risk drinking, smoking status, usual source of water and year of diagnosis, including local and global random effects within a Bayesian framework. The incidence rate ratios (IRRs) for an interquartile range (IQR) increase in THMs were estimated. RESULTS Using five year lag of exposure there was a positive association between bromoform concentration and CRC in men (IRR = 1.025, 95% CI 1.010, 1.040) but not in women (IRR = 1.003, 95% CI 0.987, 1.018). The association in men was mainly found in colon cancer with bromoform (IRR = 1.035, 95% CI 1.017, 1.053). There was no appreciable association of colorectal cancer with other species of THMs. Sensitivity analyses did not materially change the associations observed. CONCLUSION A positive association was observed between colon cancer and water bromoform concentrations in men. Given the potential population impact of such an association, further research into the relationship between THMs, particularly brominated species, and colorectal cancer is warranted.This study was conducted as part of a PhD thesis.

Rocky planet or water world? Observability of low-density lava world atmospheres
Super-Earths span a wide range of bulk densities, indicating a diversity in
interior conditions beyond that seen in the solar system. In particular, an
emerging population of low-density super-Earths may be explained by
volatile-rich interiors. Among these, low-density lava worlds have dayside
temperatures high enough to evaporate their surfaces, providing a unique
opportunity to probe their interior compositions and test for the presence of
volatiles. In this work, we investigate the atmospheric observability of
low-density lava worlds. We use a radiative-convective model to explore the
atmospheric structures and emission spectra of these planets, focusing on three
case studies with high observability metrics and sub-stellar temperatures
spanning 1900-2800 K: HD 86226c, HD 3167b and 55 Cnce. Given the
possibility of mixed volatile and silicate interior compositions for these
planets, we consider a range of mixed volatile and rock vapor atmospheric
compositions. This includes a range of volatile fractions and three volatile
compositions: water-rich (100% HO), water with CO (80% HO+20%
CO), and a desiccated O-rich scenario (67% O+33%CO). We find that
spectral features due to HO, CO, SiO and SiO are present in the
infrared emission spectra as either emission or absorption features, depending
on dayside temperature, volatile fraction and volatile composition. We further
simulate JWST secondary eclipse observations for each of the three case
studies, finding that HO and/or CO could be detected with as few as
5 eclipses. Detecting volatiles in these atmospheres would provide
crucial independent evidence that volatile-rich interiors exist among the
super-Earth population.Comment: Accepted for publication in ApJ. 26 pages, 12 figures, 2 table

Pharmacological interventions for sleepiness and sleep disturbances caused by shift work
BACKGROUND: Shift work results in sleep-wake disturbances, which cause sleepiness during night shifts and reduce sleep length and quality in daytime sleep after the night shift. In its serious form it is also called shift work sleep disorder. Various pharmacological products are used to ameliorate symptoms of sleepiness or poor sleep length and quality. OBJECTIVES: To evaluate the effects of pharmacological interventions to reduce sleepiness or to improve alertness at work and decrease sleep disturbances whilst of work, or both, in workers undertaking shift work. METHODS: Search methods: We searched CENTRAL, MEDLINE, EMBASE, PubMed and PsycINFO up to 20 September 2013 and ClinicalTrials.gov up to July 2013. We also screened reference lists of included trials and relevant reviews. Selection criteria: We included all eligible randomised controlled trials (RCTs), including cross-over RCTs, of pharmacological products among workers who were engaged in shift work (including night shifts) in their present jobs and who may or may not have had sleep problems. Primary outcomes were sleep length and sleep quality while of work, alertness and sleepiness, or fatigue at work. Data collection and analysis: Two authors independently selected studies, extracted data and assessed risk of bias in included trials. We performed meta-analyses where appropriate. MAIN RESULTS: We included 15 randomised placebo-controlled trials with 718 participants. Nine trials evaluated the effect of melatonin and two the effect of hypnotics for improving sleep problems. One trial assessed the effect of modafinil, two of armodafinil and one examined cafeine plus naps to decrease sleepiness or to increase alertness
