TL;DR: While tremendous strides have been made in understanding of who is at risk for suicide, it is incumbent upon future research efforts to focus on the development and evaluation of empirically based suicide prevention and treatment protocols.
Abstract: Objective To review critically the past 10 years of research on youth suicide. Method Research literature on youth suicide was reviewed following a systematic search of PsycINFO and Medline. The search for school-based suicide prevention programs was expanded using two education databases: ERIC and Education Full Text. Finally, manual reviews of articles' reference lists identified additional studies. The review focuses on epidemiology, risk factors, prevention strategies, and treatment protocols. Results There has been a dramatic decrease in the youth suicide rate during the past decade. Although a number of factors have been posited for the decline, one of the more plausible ones appears to be the increase in antidepressants being prescribed for adolescents during this period. Youth psychiatric disorder, a family history of suicide and psychopathology, stressful life events, and access to firearms are key risk factors for youth suicide. Exciting new findings have emerged on the biology of suicide in adults, but, while encouraging, these are yet to be replicated in youths. Promising prevention strategies, including school-based skills training for students, screening for at-risk youths, education of primary care physicians, media education, and lethal-means restriction, need continuing evaluation studies. Dialectical behavior therapy, cognitive-behavioral therapy, and treatment with antidepressants have been identified as promising treatments but have not yet been tested in a randomized clinical trial of youth suicide. Conclusions While tremendous strides have been made in our understanding of who is at risk for suicide, it is incumbent upon future research efforts to focus on the development and evaluation of empirically based suicide prevention and treatment protocols.

TL;DR: Physician education in depression recognition and treatment and restricting access to lethal methods reduce suicide rates, and other interventions need more evidence of efficacy.
Abstract: ContextIn 2002, an estimated 877 000 lives were lost worldwide through
suicide. Some developed nations have implemented national suicide prevention
plans. Although these plans generally propose multiple interventions, their
effectiveness is rarely evaluated.ObjectivesTo examine evidence for the effectiveness of specific suicide-preventive
interventions and to make recommendations for future prevention programs and
research.Data Sources and Study SelectionRelevant publications were identified via electronic searches of MEDLINE,
the Cochrane Library, and PsychINFO databases using multiple search terms
related to suicide prevention. Studies, published between 1966 and June 2005,
included those that evaluated preventative interventions in major domains;
education and awareness for the general public and for professionals; screening
tools for at-risk individuals; treatment of psychiatric disorders; restricting
access to lethal means; and responsible media reporting of suicide.Data ExtractionData were extracted on primary outcomes of interest: suicidal behavior
(completion, attempt, ideation), intermediary or secondary outcomes (treatment
seeking, identification of at-risk individuals, antidepressant prescription/use
rates, referrals), or both. Experts from 15 countries reviewed all studies.
Included articles were those that reported on completed and attempted suicide
and suicidal ideation; or, where applicable, intermediate outcomes, including
help-seeking behavior, identification of at-risk individuals, entry into treatment,
and antidepressant prescription rates. We included 3 major types of studies
for which the research question was clearly defined: systematic reviews and
meta-analyses (n = 10); quantitative studies, either randomized
controlled trials (n = 18) or cohort studies (n = 24);
and ecological, or population- based studies (n = 41). Heterogeneity
of study populations and methodology did not permit formal meta-analysis;
thus, a narrative synthesis is presented.Data SynthesisEducation of physicians and restricting access to lethal means were
found to prevent suicide. Other methods including public education, screening
programs, and media education need more testing.ConclusionsPhysician education in depression recognition and treatment and restricting
access to lethal methods reduce suicide rates. Other interventions need more
evidence of efficacy. Ascertaining which components of suicide prevention
programs are effective in reducing rates of suicide and suicide attempt is
essential in order to optimize use of limited resources.

TL;DR: All significant risk factors were more strongly related to ideation than to progression from ideation to a plan or an attempt, and prevention efforts should focus on planned attempts because of the rapid onset and unpredictability of unplanned attempts.
Abstract: Background General population survey data are presented on the lifetime prevalence of suicide attempts as well as transition probabilities to onset of ideation, plans among ideators, and attempts among ideators either with or without a plan. Risk factors for these transitions are also studied. Methods Data are from part II of the National Comorbidity Survey, a nationally representative survey carried out from 1990 to 1992 in a sample of 5877 respondents aged 15 to 54 years to study prevalences and correlates of DSM-III-R disorders. Transitions are estimated using life-table analysis. Risk factors are examined using survival analysis. Results Of the respondents, 13.5% reported lifetime ideation, 3.9% a plan, and 4.6% an attempt. Cumulative probabilities were 34% for the transition from ideation to a plan, 72% from a plan to an attempt, and 26% from ideation to an unplanned attempt. About 90% of unplanned and 60% of planned first attempts occurred within 1 year of the onset of ideation. All significant risk factors (female, previously married, age less than 25 years, in a recent cohort, poorly educated, and having 1 or more of the DSM-III-R disorders assessed in the survey) were more strongly related to ideation than to progression from ideation to a plan or an attempt. Conclusions Prevention efforts should focus on planned attempts because of the rapid onset and unpredictability of unplanned attempts. More research is needed on the determinants of unplanned attempts.

TL;DR: Subjects who received dialectical behavior therapy had fewer incidences of parasuicide and less medically severe parasuicides, were more likely to stay in individual therapy, and had fewer inpatient psychiatric days.
Abstract: A randomized clinical trial was conducted to evaluate the effectiveness of a cognitive-behavioral therapy, ie, dialectical behavior therapy, for the treatment of chronically parasuicidal women who met criteria for borderline personality disorder. The treatment lasted 1 year, with assessment every 4 months. The control condition was "treatment as usual" in the community. At most assessment points and during the entire year, the subjects who received dialectical behavior therapy had fewer incidences of parasuicide and less medically severe parasuicides, were more likely to stay in individual therapy, and had fewer inpatient psychiatric days. There were no between-group differences on measures of depression, hopelessness, suicide ideation, or reasons for living although scores on all four measures decreased throughout the year.

TL;DR: Current methods to detect FBDOs are improving, and several changes to improve the ease and timeliness of reporting FBDO data are occurring (e.g., a revised form to simplify FBDO reporting by state health departments and electronic reporting methods).
Abstract: Problem/condition Since 1973, CDC has maintained a collaborative surveillance program for collection and periodic reporting of data on the occurrence and causes of foodborne-disease outbreaks (FBDOs) in the United States. Reporting period covered This summary reviews data from January 1993 through December 1997. Description of system The Foodborne-Disease Outbreak Surveillance System reviews data concerning FBDOs, defined as the occurrence of two or more cases of a similar illness resulting from the ingestion of a common food. State and local public health departments have primary responsibility for identifying and investigating FBDOs. State, local, and territorial health departments use a standard form to report these outbreaks to CDC. Results During 1993-1997, a total of 2,751 outbreaks of foodborne disease were reported (489 in 1993, 653 in 1994, 628 in 1995, 477 in 1996, and 504 in 1997). These outbreaks caused a reported 86,058 persons to become ill. Among outbreaks for which the etiology was determined, bacterial pathogens caused the largest percentage of outbreaks (75%) and the largest percentage of cases (86%). Salmonella serotype Enteritidis accounted for the largest number of outbreaks, cases, and deaths; most of these outbreaks were attributed to eating eggs. Chemical agents caused 17% of outbreaks and 1% of cases; viruses, 6% of outbreaks and 8% of cases; and parasites, 2% of outbreaks and 5% of cases. Interpretation The annual number of FBDOs reported to CDC did not change substantially during this period or from previous years. During this reporting period, S. Enteritidis continued to be a major cause of illness and death. In addition, multistate outbreaks caused by contaminated produce and outbreaks caused by Escherichia coli O157:H7 remained prominent. Actions taken Current methods to detect FBDOs are improving, and several changes to improve the ease and timeliness of reporting FBDO data are occurring (e.g., a revised form to simplify FBDO reporting by state health departments and electronic reporting methods). State and local health departments continue to investigate and report FBDOs as part of efforts to better understand and define the epidemiology of foodborne disease in the United States. At the regional and national levels, surveillance data provide an indication of the etiologic agents, vehicles of transmission, and contributing factors associated with FBDOs and help direct public health actions to reduce illness and death caused by FBDOs.

TL;DR: A stress-diathesis model is proposed in which the risk for suicidal acts is determined not merely by a psychiatric illness but also by a diathesis, reflected in tendencies to experience more suicidal ideation and to be more impulsive and, therefore, more likely to act on suicidal feelings.
Abstract: OBJECTIVE: Risk factors for suicide attempts have rarely been studied comprehensively in more than one psychiatric disorder, preventing estimation of the relative importance and the generalizability of different putative risk factors across psychiatric diagnoses. The authors conducted a study of suicide attempts in patients with mood disorders, psychoses, and other diagnoses. Their goal was to determine the generalizability and relative importance of risk factors for suicidal acts across diagnostic boundaries and to develop a hypothetical, explanatory, and predictive model of suicidal behavior that can subsequently be tested in a prospective study. METHOD: Following admission to a university psychiatric hospital, 347 consecutive patients who were 14–72 years old (51% were male and 68% were Caucasian) were recruited for study. Structured clinical interviews generated axis I and axis II diagnoses. Lifetime suicidal acts, traits of aggression and impulsivity, objective and subjective severity of acute psycho...

TL;DR: In this paper, the authors reported a total of 22 waterborne-disease outbreaks associated with drinking water and recreational lake water, which caused an estimated total of 2,567 persons to become ill. No deaths were reported.
Abstract: Problem/condition Since 1971, CDC and the U.S. Environmental Protection Agency have maintained a collaborative surveillance system for collecting and periodically reporting data that relate to occurrences and causes of waterborne-disease outbreaks (WBDOs). Reporting period covered This summary includes data for January 1995 through December 1996 and previously unreported outbreaks in 1994. Description of the system The surveillance system includes data about outbreaks associated with drinking water and recreational water. State, territorial, and local public health departments are primarily responsible for detecting and investigating WBDOs and for voluntarily reporting them to CDC on a standard form. Results For the period 1995-1996, 13 states reported a total of 22 outbreaks associated with drinking water. These outbreaks caused an estimated total of 2,567 persons to become ill. No deaths were reported. The microbe or chemical that caused the outbreak was identified for 14 (63.6%) of the 22 outbreaks. Giardia lamblia and Shigella sonnei each caused two (9.1%) of the 22 outbreaks; Escherichia coli O157:H7, Plesiomonas shigelloides, and a small round structured virus were implicated for one outbreak (4.5%) each. One of the two outbreaks of giardiasis involved the largest number of cases, with an estimated 1,449 ill persons. Seven outbreaks (31.8% of 22) of chemical poisoning, which involved a total of 90 persons, were reported. Copper and nitrite were associated with two outbreaks (9.1% of 22) each and sodium hydroxide, chlorine, and concentrated liquid soap with one outbreak (4.5%) each. Eleven (50.0%) of the 22 outbreaks were linked to well water, eight in noncommunity and three in community systems. Only three of the 10 outbreaks associated with community water systems were caused by problems at water treatment plants; the other seven resulted from problems in the water distribution systems and plumbing of individual facilities (e.g., a restaurant). Six of the seven outbreaks were associated with chemical contamination of the drinking water; the seventh outbreak was attributed to a small round structured virus. Four of the seven outbreaks occurred because of backflow or backsiphonage through a cross-connection, and two occurred because of high levels of copper that leached into water after the installation of new plumbing. For three of the four outbreaks caused by contamination from a cross-connection, an improperly installed vacuum breaker or a faulty backflow prevention device was identified; no protection against backsiphonage was found for the fourth outbreak. Thirty-seven outbreaks from 17 states were attributed to recreational water exposure and affected an estimated 9,129 persons, including 8,449 persons in two large outbreaks of cryptosporidiosis. Twenty-two (59.5%) of these 37 were outbreaks of gastroenteritis; nine (24.3%) were outbreaks of dermatitis; and six (16.2%) were single cases of primary amebic meningoencephalitis caused by Naegleria fowleri, all of which were fatal. The etiologic agent was identified for 33 (89.2%) of the 37 outbreaks. Six (27.3%) of the 22 outbreaks of gastroenteritis were caused by Cryptosporidium parvum and six (27.3%) by E. coli O157:H7. All of the latter were associated with unchlorinated water (i.e., in lakes) or inadequately chlorinated water (i.e., in a pool). Thirteen (59.1%) of these 22 outbreaks were associated with lake water, eight (36.4%) with swimming or wading pools, and one(4.5%) with a hot spring. Of the nine outbreaks of dermatitis, seven (77.8%) were outbreaks of Pseudomonas dermatitis associated with hot tubs, and two (22.2%) were lake-associated outbreaks of swimmer's itch caused by Schistosoma species. Interpretation WBDOs caused by E. coli O157:H7 were reported more frequently than in previous years and were associated primarily with recreational lake water. This finding suggests the need for better monitoring of water quality and identification of sources of
