Some reporters, politicians, and doctors have described current cases as a “re-emergence” of these diseases, based on the notion that they had been eliminated. However, silicosis persisted in centuries-old industries like sandblasting and stonemasonry and coal workers pneumoconiosis (CWP) continued in coal mining. Until recently, their presence was obscured by a combination of factors such as misdiagnosis, especially if there was a history of smoking; the failure to follow up workers thought to have silicosis or CWP; the long latency period between dust exposure and disease onset that can conceal the link between the two; and the lack of data collection that may have revealed their presence. As the recent Queensland government inquiry into CWP noted, current cases are more accurately a reidentification.

BackgroundThis study investigated three questions with major implications for suicide prevention: the sensitivity of the history of previous suicide attempt(s) as an indicator of suicide risk, the time interval from a preceding suicide attempt to the fatal one, and switching of suicide methods by those eventually completing suicide.MethodThe lifetime history of suicide attempts and the methods the victims (n=1397) used were examined in a nationwide psychological autopsy study comprising all suicides in Finland within a 12-month research period in 1987–1988.ResultsOverall, 56% of suicide victims were found to have died at their first suicide attempt, more males (62%) than females (38%). In 19% of males and 39% of females the victim had made a non-fatal attempt during the final year. Of the victims with previous attempts, 82% had used at least two different methods in their suicide attempts (the fatal included).ConclusionsMost male and a substantial proportion of female suicides die in their first suicide attempt, a fact that necessitates early recognition of suicide risk, particularly among males. Recognition of periods of high suicide risk on the grounds of recent non-fatal suicide attempts is likely to be important for suicide prevention among females. Subjects completing suicide commonly switch from one suicide method to another, a finding that weakens but does not negate the credibility of restrictions on the availability of lethal methods as a preventive measure.

ObjectivesThe natural history of coal workers’ pneumoconiosis (CWP) after cessation of exposure remains poorly understood.MethodsWe characterised the development of and progression to radiographic progressive massive fibrosis (PMF) among former US coal miners who applied for US federal benefits at least two times between 1 January 2000 and 31 December 2013. International Labour Office classifications of chest radiographs (CXRs) were used to determine initial and subsequent disease severity. Multivariable logistic regression models were used to identify major predictors of disease progression.ResultsA total of 3351 former miners applying for benefits without evidence of PMF at the time of their initial evaluation had subsequent CXRs. On average, these miners were 59.7 years of age and had 22 years of coal mine employment. At the time of their first CXR, 46.7% of miners had evidence of simple CWP. At the time of their last CXR, 111 miners (3.3%) had radiographic evidence of PMF. Nearly half of all miners who progressed to PMF did so in 5 years or less. Main predictors of progression included younger age and severity of simple CWP at the time of initial CXR.ConclusionsThis study provides further evidence that radiographic CWP may develop and/or progress absent further exposure, even among miners with no evidence of radiographic pneumoconiosis after leaving the industry. Former miners should undergo regular medical surveillance because of the risk for disease progression.

Background. Female nurses appear to have an increased risk of suicide but the reasons are unknown.Method. We have concluded a study of nurse suicides (N = 106) in England and Wales, including a psychological autopsy study (N = 42) and case–control comparison with living nurses (N = 84).Results. Nearly three-quarters of the nurse suicides had previous contact with psychiatric services and almost half had been psychiatric in-patients in the past. There were particularly marked differences between the cases and controls for current psychiatric disorder (90·5% v. 7·1%, OR = 68·5), personality disorder (38·1% v. 1·2%, OR = 32), and history of deliberate self-harm (71·4% v. 2· 4%, OR = 58·5). Family background and social factors (especially concerning interpersonal relationships) also distinguished the two groups. Smoking and serious alcohol abuse were much more frequent in the suicides. There was some indication that while many of the suicides were in contact with psychiatric services, care may not have been optimal in some cases.Conclusions. The most important strategies for suicide prevention in nurses are in prevention, detection and management of psychiatric disorders. In assessing suicide risk a history of DSH and the presence of comorbid psychiatric and personality disorders are particularly important.

BackgroundSuicides among people with schizophrenia are commonly believed to be impulsive and to occur unexpectedly.MethodAs part of the National Suicide Prevention Project in Finland, a nationwide psychological autopsy study, suicide victims with DSM-III-R schizophrenia (n=86; n=64 in the active illness phase) and others (n=1 109; n=666 without any evidence for psychosis) were compared for communication of suicidal intent (CSI), as well as previous suicide attempts known by the next of kin and/or an attending health care professional during the latest treatment relationship.ResultsMore victims with schizophrenia (84%) had a history of previous CSI, and/or had made previous suicide attempt(s) than others (70%). Also, victims with active illness schizophrenia (56%) had more CSI and/or had made suicide attempts during their last three months than victims with no psychosis (41%).ConclusionsCSI and/or suicide attempts occur at least as often in people with schizophrenia as in those without schizophrenia, even in the active phase of the illness.
