The role of electronic journals in reducing publication bias.
Publication bias poses a threat to the validity of medical research. It is unlikely that conventional paper journals can solve the problem of selective publication of studies with striking results because of their space limitation and need to be newsworthy. Peer-reviewed electronic journals without limitation of space might provide a solution to this paradox. To maintain the integrity of medical publication, editorial policy needs to be changed to accept clinical trials for publication, based only on the methodological criteria and not on the impact of their findings.
The early repetition of deliberate self harm.
The objective was to determine the pattern of repeated deliberate self harm (DSH) in a busy inner-city teaching hospital. We undertook a retrospective cohort analytical study for all 1,576 DSH patients seen for assessment over a two-year period. Age, sex and previous DSH were noted at index episode (562 (36%) reported a previous history). Each patient was followed up for 12 months and repetition of DSH was recorded. DSH was repeated by 193 (12%) within one year, 138 (72%) once and 55 (28%) more than once. Repetition was more common and occurred much more quickly in those with a previous history than those without (relative risk: 3.4). Median time to repetition was 12 weeks but about 10% repeated within a week. The results were similar for men and women. This implies that previous history is the single most useful predictor in the repetition of DSH. Repetition occurs quickly and most rapidly in those who have previously harmed themselves. Intervention aimed at reducing repetition of self harm must be delivered within days, not weeks.
Mental health promotion in high-risk groups.
This article summarises a systematic review of the literature on promoting mental health in high-risk groups. The review suggests that there are a variety of effective interventions for preventing mental health problems in high-risk groups. This has implications for the scope of practice of nurses and others working in a range of services, including midwifery, health visiting, school health, mental health, terminal care, district nursing and primary health care.
