Relationship between suicide and holidays.
(73/2091)
Employing the vital statistics from January 1, 1979 to December 31, 1994 in Hokkaido Prefecture, Japan, we investigated the relationship between suicide (ICD 9 code, El15) and days of the week. In one day 1.97 males and 0.98 females committed suicide on average. On Saturdays the number of suicides per day was the smallest. On Mondays it was the highest. When the days were classified into (1) a holiday, (2) the day before a holiday, (3) the day after a holiday (4) the day both before and after a holiday and (5) others, the rate of suicide was the lowest in the days before a holiday. In the days after a holiday, however, the rate was the highest. The same tendency was also noted when the subjects were classified into several subgroups from the viewpoint of ages, seasons or calendar years. The time relation of holidays seemed to have something to do with the intention to commit suicide. (+info)
Effects of acute tryptophan depletion on mood and suicidal ideation in bipolar patients symptomatically stable on lithium.
(74/2091)
BACKGROUND: Previous studies suggest that brain serotonin neurotransmission may mediate the actions of lithium carbonate. Acute tryptophan depletion reduces brain serotonin and allows the study of this neurotransmitter in patient groups. AIMS: To examine the effects of acute tryptophan depletion on mood and suicidal ideation in bipolar patients who were symptomatically stable on lithium. METHOD: Nineteen subjects satisfying DSM-IV criteria for bipolar I disorder participated in a within-subject, double-blind, placebo-controlled random-order crossover study. Symptoms were evaluated following acute tryptophan depletion, which was induced by a 100 g amino acid drink following an overnight fast. RESULTS: Plasma tryptophan fell significantly after the depleting drink, but not after the control drink (P < 0.05, paired t-test, mean reduction 83%). No significant changes in mood or suicidality scores were recorded after acute tryptophan depletion. CONCLUSIONS: Acute tryptophan depletion does not reverse lithium's effects on mood and suicidality in bipolar disorder. (+info)
Effect of death of Diana, princess of Wales on suicide and deliberate self-harm.
(75/2091)
BACKGROUND: The death of the Princess of Wales in 1997 was followed by widespread public mourning. Such major events may influence suicidal behaviour. AIMS: To assess the impact of the Princess's death on suicide and deliberate self-harm (DSH). METHOD: Analysis, using Poisson regression, of the number of suicides and open verdicts ('suicides') in England and Wales following the Princess's death compared to the 3 months beforehand, and the equivalent periods in 1992-1996. Similar analysis on DSH presentations to a general hospital. RESULTS: Suicides increased during the month following the Princess's funeral (+17.4%). This was particularly marked in females (+33.7%), especially those aged 25-44 years (+45.1%). Suicides did not fall in the week between the death and the funeral. Presentations for DSH increased significantly during the week following the death (+44.3%), especially in females (+65.1%). Examination of case notes suggested that the influence of the death was largely through amplification of personal losses or exacerbation of existing distress. CONCLUSIONS: The death of a major public figure can influence rates of suicidal behaviour. For DSH, the impact may be immediate, but for suicide it may be delayed. (+info)
Injury mortality in East Germany.
(76/2091)
OBJECTIVES: This study determined the effects of social changes in East Germany since 1989 on patterns of injury mortality. METHODS: Death certificate data regarding injuries from 1980 through 1995 and police data regarding traffic injuries in East Germany from 1980 through 1998 were compared with similar data from West Germany. RESULTS: The number of motor vehicle-related injuries and deaths in East Germany increased dramatically between 1989 and 1991, whereas those in West Germany declined slightly. The increased mortality in the more rural East has especially involved young men driving automobiles on rural roads and has persisted since reunification of East and West Germany. Falls, other accidents, and suicides have shown no such effect. Homicide among East German men has increased but remains uncommon. CONCLUSIONS: Recent social changes in East Germany, including increased access to motor vehicles and decreased restrictions on personal freedom, have been associated with increased motor vehicle crashes and mortality, especially among young men and on rural roads.

Cognitive approach to depression and suicidal thinking in psychosis. 1. Ontogeny of post-psychotic depression.
(77/2091)
BACKGROUND: Depression in schizophrenia is a rather neglected field of study, perhaps because of its confused nosological status. Three course patterns of depression in schizophrenia, including post-psychotic depression (PPD), are proposed. AIMS: We chart the ontogeny of depression and psychotic symptoms from the acute psychotic episode over a 12-month period and test the validity of the proposed course patterns. METHOD: One hundred and five patients with ICD-10 schizophrenia were followed up on five occasions over 12 months following the acute episode, taking measures of depression, positive symptoms, negative symptoms, neuroleptic exposure and side-effects. RESULTS: Depression accompanied acute psychosis in 70% of cases and remitted in line with the psychosis; 36% developed PPD without a concomitant increase in psychotic symptoms. CONCLUSIONS: The results provided support for the validity of two of the three course patterns of depression in schizophrenia, including PPD. Post-psychotic depression occurs de novo without concomitant change in positive or negative symptoms. (+info)
Cognitive approach to depression and suicidal thinking in psychosis. 2. Testing the validity of a social ranking model.
(78/2091)
BACKGROUND: In paper I we reported that depression in the acute stage remitted in line with the psychosis and that 36% of patients developed post-psychotic depression (PPD). AIMS: We apply our cognitive framework to PPD and chart the appraisal of self and psychosis and their link with the later emergence of PPD. METHOD: Patients with ICD-10 schizophrenia (n=105) were followed up over 12 months following the acute episode, taking measures of depression, working self-concept, cognitive vulnerability, insight and appraisals of psychosis. RESULTS: Before developing PPD, these patients felt greater loss, humiliation and entrapment by their illness than those who relapsed or did not become depressed, and were more likely to see their future selves in 'lower status' roles. Upon becoming depressed, participants developed greater insight, lower self-esteem and a worsening of their appraisals of psychosis. CONCLUSIONS: Depression in psychosis arises from the individual's appraisal of psychosis and its implications for his/her perceived social identity, position and 'group fit'. Patients developing PPD feel forced to accept a subordinate role without opportunity for escape. Implications for treatment are discussed. (+info)
Gender differences in risk factors for suicide in Denmark.
(79/2091)
BACKGROUND: Gender is one of the most frequently replicated predictors for suicide. AIMS: To identify risk factors for suicide among males and females and to investigate whether risk factors for suicide differ by gender. METHOD: A time-matched nested case-control design was performed using Danish longitudinal register databases to obtain 811 suicide cases and 79 871 controls. Data were analysed using conditional logistic regression. RESULTS: A history of hospitalised mental illness was the most marked risk factor for suicide for both genders. Unemployment, retirement, being single and sickness absence were significant risk factors for men, whereas having a child <2 years old was significantly protective for women. The relative risks for suicide differed significantly between genders according to psychiatric admission status and being the parent of a child <2 years. However, adjustment for these factors did not eliminate the gender difference in suicide risk. CONCLUSIONS: Risk factors for suicide differed by gender and gender differences could not be explained by differential exposure to known risk factors. (+info)
The effects of race/ethnicity, income, and family structure on adolescent risk behaviors.
(80/2091)
OBJECTIVES: The study examined the unique and combined contributions of race/ethnicity, income, and family structure to adolescent cigarette smoking, alcohol use, involvement with violence, suicidal thoughts or attempts, and sexual intercourse. METHODS: Analyses were based on the National Longitudinal Study of Adolescent Health. A nationally representative sample of 7th to 12th graders participated in in-home interviews, as did a resident parent for 85.6% of the adolescent subjects. The final sample included 10,803 White, Black, and Hispanic 7th to 12th graders. RESULTS: White adolescents were more likely to smoke cigarettes, drink alcohol, and attempt suicide in the younger years than were Black and Hispanic youths. Black youths were more likely to have had sexual intercourse; both Black and Hispanic youths were more likely than White teens to engage in violence. Controlling for gender, race/ethnicity, income, and family structure together explained no more than 10% of the variance in each of the 5 risk behaviors among younger adolescents and no more than 7% among older youths. CONCLUSIONS: Findings suggest that when taken together, race/ethnicity, income, and family structure provide only limited understanding of adolescent risk behaviors. (+info)
