Review
Burden of reduced work productivity among people with chronic knee pain: a systematic review.
The aims of this systematic review were to determine the prevalence of reduced work productivity among people with chronic knee pain as well as specifically categorise determinants of work productivity losses into individual, disease and work-related factors, conduct an evaluation of study methodological quality and present a best-evidence synthesis. ⋯ PROSPERO registry number: CRD42013004137.

Review Meta Analysis
Influence of poor health on exit from paid employment: a systematic review.
The objective was to provide a systematic literature review on associations between poor health and exit from paid employment through disability pension, unemployment and early retirement, and to estimate the magnitude of these associations using meta-analyses. Medline and Embase databases were searched for longitudinal studies on the relationship between health measures and exit from paid employment. Random-effects models were used to estimate the pooled effects. ⋯ Chronic disease was a risk factor for transition into disability pension (RR 2.11; 95% CI 1.90 to 2.33) or unemployment (RR 1.31; 95% CI 1.14 to 1.50), but not for early retirement. This meta-analysis showed that poor health, particularly self-perceived health, is a risk factor for exit from paid employment through disability pension, unemployment and, to a lesser extent, early retirement. To increase sustained employability it should be considered to implement workplace interventions that promote good health.

Review Meta Analysis
Work activities and risk of prematurity, low birth weight and pre-eclampsia: an updated review with meta-analysis.
We assessed the evidence relating preterm delivery (PTD), low birth weight, small for gestational age (SGA), pre-eclampsia and gestational hypertension to five occupational exposures (working hours, shift work, lifting, standing and physical workload). We conducted a systematic search in Medline and Embase (1966 to 2011), updating a previous search with a further 6 years of observations. ⋯ The balance of evidence is against large effects for the associations investigated. As the evidence base has grown, estimates of risk in relation to these outcomes have become smaller.

To give an overview of the evidence on the cost-effectiveness (CE) and financial return of worksite mental health interventions. ⋯ Due to a limited number of economic evaluations on worksite mental health interventions of which a majority was lacking methodological quality or lacking evidence, only a tentative conclusion can be drawn from the results of this systematic review. Worksite interventions to prevent or treat mental health problems might be cost-effective, while those RTW interventions that included a full economic evaluation aimed at depressed employees do not seem to be cost-beneficial. More high-quality economic evaluation studies of effective worksite mental health interventions are needed to get more insight into the economic impact of worksite mental health interventions.

The association between ambient air pollution exposure and lung cancer risk has been investigated in prospective studies and the results are generally consistent, indicating that long-term exposure to air pollution may cause lung cancer. Despite the prospective nature and consistent findings of these studies, causality assessment can benefit from biomarker research. In the present systematic review, we assess the contribution of intermediate biomarkers in epidemiological studies, to ascertain whether their measurement reinforces causal reasoning. ⋯ These biomarkers cover the whole spectrum of disease onset and progression from external exposure to tumour formation and some have also been suggested as risk predictors of future cancer, reinforcing causal reasoning. However, methodological issues such as confounding, publication bias and use of surrogate tissues instead of target tissues in studies on these markers are of concern. The identified biological markers have potential to shed light on the pathways of carcinogenesis, thus defining the association more clearly for public health interventions.
