1. UK: Safety professionals call for action on diesel
The Institution of Occupational Safety and Health (IOSH) - the professional health and safety officers body - has called on the UK government to reduce worker exposure to cancer-causing diesel particulates.
Responding to the UK's newly published Air Quality Plan, IOSH is encouraging the government to support its No Time to Lose campaign, which aims to tackle the burden of occupational cancer and help to offer solutions to businesses looking to reduce the impact of diesel particulates. According to IOSH the government's plan fails to address the cancer-causing elements of diesel exhaust emissions. It is estimated that more than 650 people die every year in Britain of lung or bladder cancer linked to exposure to diesel exhaust fumes at work, in addition to approximately 800 new cases of cancer caused by diesel-exhaust-fumes exposure are registered each year. Bus, car and lorry (truck) maintenance engineers, bus and lorry drivers, fork lift truck drivers and other warehouse workers, tractor drivers, miners and construction workers are just some examples of occupations that are exposed to diesel exhaust in the course of their work. Unite the Union has produced a resource page on the dangers of diesel exhaust, which includes a link to their own guide for safety representatives on tackling the issue. Since June 2012, diesel exhaust emissions have been classified by the International Agency for Research into Cancer as a Group 1 Carcinogen, which means that they cause cancer in humans.

2. Too much sitting - bad for the brain too?
There has been much research on the potential negative effects on our health of sitting for long periods. A 2016 literature review showed that prolonged unbroken sitting time is associated with a range of health problems including musculoskeletal disorders, cardiovascular disease, diabetes, obesity, some cancers and premature mortality. Sedentary behavior has been linked to poor glycemic control and increased risk of all-cause mortality. (see Sedentary Work for more information).
Now it seems that physical inactivity and prolonged sitting may also affect our brains. Researchers from the University of Western Australia, in collaboration with the Baker Heart and Diabetes Institute, are examining the prolonged negative impact of sitting on our brains. In the current project, the researchers highlight the role of glycemic control in maintaining brain function. They suggest that reducing and replacing sedentary behavior with intermittent light-intensity physical activity may protect against cognitive decline by reducing glycemic variability. They concluded that more research is needed to understand the impact of poor glycemic control on brain function and whether practical interventions aimed at reducing and replacing sedentary behavior with intermittent light intensity physical activity can help slow cognitive decline.

3. NSW: experiences of injured workers
Previous research, based on data, into injured workers and return to work had indicated that if they can maintain their work-related connections, their chances of recovery are significantly heightened. Researchers from Sydney's Macquarie University, conducted two hour interviews with injured workers and found their experiences not what they expected. The researchers identified three 'themes':
A prevailing expectation that managers would maintain meaningful engagement with the injured worker, even while the worker was away. Too often this did not occur. In fact, this was sometimes totally discouraged. As a result, those with psychological injuries reported a greater tendency to keep them hidden since they feared what would happen if the invisible became visible.
A noticeable change in attitude among managers as soon as workers lodged their workers' compensation claims. This change was negative.
(Un)reasonable adjustment: in the majority of cases, managers expressed impatience, became inflexible, engaged in harassment, ignored injury recovery plans, refused to modify duties, and applied substantial psychological pressure to get employees to return and perform.
Underpinning these experiences was a perception among managers that most workers' compensation claims are exaggerated. The researchers concluded: "not only that the NSW Workers' compensation system is failing to deliver a timely and durable return to work for many injured workers, but also that, for many, problematic and often pathogenic interactions with employers and insurers are resulting in exacerbated and secondary injuries and negative social and vocational consequences."

4. Brain damage in US football players
A study of American football players' brains has found that 99 per cent of professional National Football League (NFL) athletes tested had a disease associated with head injuries. 202 deceased players were studied, 111 of them from the NFL. All but one former National Football League player were found to have chronic traumatic encephalopathy (CTE) which is a degenerative disease found in people who have suffered repeated blows to the head. It is found in professional athletes in American football, rugby, ice hockey, boxing, wrestling, rodeo riding and other contact sports. It causes a build-up of so-called tau proteins which can disable neuro-pathways and cause memory loss, impaired judgment, confusion and a variety of other mental health issues. In 2015, a federal judge approved a class-action lawsuit brought against the NFL by thousands of players, who had alleged they had suffered brain damage as a result of concussions. The NFL in 2016 acknowledged for the first time that there is a connection between CTE and football.
