BackgroundBetween 15 and 20% of prevalent cases of chronic obstructive pulmonary disease (COPD) have been attributed to occupational exposures to vapours, gases, dusts and fumes. Dust at construction sites is still a challenge, but no overview exists of COPD among construction workers.AimsTo assess the occurrence of COPD among construction workers.MethodsWe performed a systematic search in PubMed and Embase between 1 January 1990 and 31 August 2016 in order to identify epidemiological studies with a risk estimate for either COPD morbidity/mortality or a spirometry-based definition of airway obstruction among workers in the construction industry. The authors independently assessed studies to determine their eligibility and performed a quality assessment of the included papers.ResultsTwelve studies were included. Nine studies found a statistically significant association between COPD and work in the construction industry, although only among never-smokers in one study and only for the period after 2000 in another study. One study found that the annual decline in forced expiratory volume in 1 s was significantly higher among construction workers compared with bus drivers.ConclusionsThis review suggests that COPD occurs more often among construction workers than among workers who are not exposed to construction dust. It is not possible to draw any conclusions on specific subgroups as most studies analysed construction workers as one united group. In addition, no potential exposure–effect relationship could be identified.

Background: Insomnia is a common sleep disorder for adults with depression, with major impact on their quality of life. Previous trials suggest that listening to music may be helpful in the treatment of sleep disturbances in healthy populations, including students and elderly. In addition, small studies with clinical populations of traumatized refugees, adults with chronic insomnia and adults with depression insomnia add to the evidence base. However, the impact of music listening in the treatment of depression related insomnia is not well documented. Objective: To examine the efficacy of music listening on sleep quality, symptoms of depression, and quality of life in adults with depression-related insomnia. Method: A single-center randomized controlled trial (RCT) in a two-arm parallel-group design is conducted and reported according to the CONSORT guidelines. The trial consists of an experimental group and a standard care control group. Both groups receive standard treatment for depression following Danish clinical guidelines in an outpatient psychiatry unit. The experimental group listens to music for a minimum of 30 minutes at bedtime for 4 weeks. Discussion: This trial will provide information on the efficacy of music intervention as a non-pharmacological intervention in the treatment of depression-related insomnia. This study will provide novel knowledge concerning music medicine as an evidence-based treatment for depression. Trial Registration: Clinicaltrials.gov. ID NCT03676491, registered on 19 September 2018.
