Are suicide attempters wired differently?

Objective: Limited research exists on internal risk processes in suicide attempters and factors that distinguish them from non-suicidal, depressive individuals. In this qualitative study, we investigated Plans, motives, and underlying self-regulatory processes of the two groups and conducted a comparative analysis. Methods: We analyzed narrative interviews of 17 suicide attempters and intake interviews of 17 non-suicidal, depressive patients using Plan Analysis. Then, we developed a prototypical Plan structure for both groups. Results: Suicidal behavior serves various Plans only found in suicide attempters. Plans of this group are especially related to social perfectionism and withdrawal in order to protect their self-esteem. Depressive patients employ several interpersonal control and coping strategies, which might help prevent suicidal behavior. Conclusion: The prototypical Plan structure of suicide attempters may be a valuable tool for clinicians to detect critical Plans and motives in their interaction with patients, which are related to suicide risk.

Assisted and unassisted suicide in men and women: longitudinal study of the Swiss population.

BackgroundIn Switzerland assisted suicide is legal if no self-interest is involved.AimsTo compare the strength and direction of associations with sociodemographic factors between assisted and unassisted suicides.MethodWe calculated rates and used Cox and logistic regression models in a longitudinal study of the Swiss population.ResultsAnalyses were based on 5 004 403 people, 1301 assisted and 5708 unassisted suicides from 2003 to 2008. The rate of unassisted suicides was higher in men than in women, rates of assisted suicides were similar in men and women. Higher education was positively associated with assisted suicide, but negatively with unassisted. Living alone, having no children and no religious affiliation were associated with higher rates of both.ConclusionsSome situations that indicate greater vulnerability such as living alone were associated with both assisted and unassisted suicide. Among the terminally ill, women were more likely to choose assisted suicide, whereas men died more often by unassisted suicide.

The Right to Die Debate: The Demonization of Dr. Kevorkian and the Creation of a Moral Panic Surrounding Physician-Assisted Suicide in the United States

The Right to Die Debate is a recent but highly controversial moral matter. In particular, physician-assisted suicide (PAS) is an issue that has been evaded by the medical community for years. As of 1990, most states had never encountered the issue before and therefore did not have any laws in place to prohibit PAS (Strate et. al, 2005). Dr. Jack Kevorkian, a retired pathologist from Royal Oak Michigan was the first to publicly address PAS. He brought the issue into the limelight through a bizarre and crude series of assisted deaths that had a lasting impact on not only the Right to Die Debate as whole, but on public policy and both federal and state governmental agendas. This study focuses on the way in which the media, in particular the New York Times (NYT) has portrayed Dr. Jack Kevorkian as incompetent, morally culpable and in an overall negative light in the past twenty years. Applying Stanley Cohen’s 1972 theory of moral panic, a content analysis of NYT media publications between 1990 and 1999 supports Cohen’s theory and reveals that the media has created a moral panic surrounding Kevorkian. This has in turn led to public policy that prevents both terminally ill individuals and their doctors from having a desirable choice; that of voluntary euthanasia and PAS.

A cross-sectional study of disparities in suicide ideation between Hispanic and non-Hispanic white female adolescents

Suicide is recognized as a major public health and clinical problem in the United States. One fifth of adolescents in the United States seriously consider suicide each year, and about 8% of high school students attempt suicide at least once. Hispanic ethnicity constitutes a risk factor for suicidal ideation and suicide attempts, with Hispanic females at highest risk. Nevertheless, published studies on suicidal behavior in Hispanic female adolescents are extremely limited and focus on suicidal ideation in school samples. Given the severity of the problem and the paucity of information on this topic, more research on ethnic differences in suicidal ideation in community samples of high-risk children is urgently needed. This cross-sectional study delineated differences in suicide ideation between Hispanic female adolescents and non-Hispanic white female adolescents attending a mental health clinic and examined the association of ethnicity with suicide ideation independent of other known risk factors. Data were accrued between June 2004 and December 2008 in a Harris County Mental Health and Mental Retardation Association (MHMRA) clinic. Data were limited to adolescents who were Harris County Residents between the ages of 10 to 17 years when they were admitted to the clinic. The objective of this study was to determine whether differences in socio-demographic and clinical variables play a significant role in ethnic disparities in suicide ideation. A series of logistic regressions were performed to estimate the association between ethnicity and suicide ideation after controlling for potentially confounding factors. ^ Results showed an interaction between Hispanic ethnicity and having a history of treatment: Hispanic girls having history of treatment had lower odds of having suicide ideation than Hispanic girls without such a history. After adjusting for treatment history, family problems, substance use, juvenile justice involvement, current treatment, and age, Hispanic girls had 1.86 times the odds of having suicide ideation than non Hispanic girls (OR=1.86, 95% CI=0.88-1.46). Although additional studies on community samples of high risk adolescents are needed to verify these findings, our study highlights the fact that Hispanic girls are at significantly higher risk and need to be targeted for prevention and treatment efforts. ^

THE APPLICATION OF CIRRHOSIS MORTALITY AND SUICIDE MORTALITY AS INDICATORS FOR ALCOHOLISM PLANNING

This study provides a review of the current alcoholism planning process of the Houston-Galveston planning process of the Houston-Galveston Area Council, an agency carrying out planning for a thirteen county region in surrounding Houston, Texas. The four central groups involved in this planning are identified, and the role that each plays and how it effects the planning outcomes is discussed.^ The most substantive outcome of the Houston-Galveston Area Council's alcoholism planning, the Regional Alcoholism/Alcohol Abuse Plan is examined. Many of the shortcomings in the data provided, and the lack of other data necessary for planning are offered.^ A problem oriented planning model is presented as an alternative to the Houston-Galveston Area Council's current service oriented approach to alcoholism planning. Five primary phases of the model, identification of the problem, statement of objectives, selection of alternative programs, implementation, and evaluation, are presented, and an overview of the tasks involved in the application of this model to alcoholism planning is offered.^ A specific aspect of the model, the use of problem status indicators is explored using cirrhosis and suicide mortality data. A review of the literature suggests that based on five criteria, availability, subgroup identification, validity, reliability, and sensitivity, both suicide and cirrhosis are suitable as indicators of the alcohol problem when combined with other indicators.^ Cirrhosis and suicide mortality data are examined for the thirteen county Houston-Galveston Region for the years 1969 through 1976. Data limitations preclude definite conclusions concerning the alcohol problem in the region. Three hypotheses about the nature of the regional alcohol problem are presented. First, there appears to be no linear trend in the number of alcoholics that are at risk of suicide and cirrhosis mortality. Second, the number of alcoholics in the metropolitan areas seems to be greater than the number of rural areas. Third, the number of male alcoholics at risk of cirrhosis and suicide mortality is greater than the number of female alcoholics.^

Attempted hydrogen–deuterium exchange of the protio-trimethyloxonium dication (CH3)3OH2+, study of methylating ability of (CH3)3O+ in superacids and theoretical investigations

Attempted hydrogen–deuterium exchange of trimethyloxonium ion, (CH3)3O+ with excess of 1:1 2HF/SbF5 superacid at −30°C over a period of 30 days showed no exchange. Theoretical calculations at the MP2/6–31G** level are in accord with the lack of hydrogen–deuterium exchange in the methyl group of the (CH3)3O+ cation as protonation (protosolvation) prefers the oxygen lone pair of electrons, instead of a C—H bond. Methylation of aromatics with the (CH3)3O+CF3SO3− in CF3SO3H and 2CF3SO3H:B(O3SCF3)3 was also studied. Whereas in triflic acid no alkylation was observed, in triflatoboric acid, a powerful superacid, alkylation takes place, indicating protolytic activation of the trimethyloxonium ion.

Inactivation of the α C protein antigen gene, bca, by a novel shuttle/suicide vector results in attenuation of virulence and immunity in group B Streptococcus

The α C protein of group B Streptococcus (GBS) is a major surface-associated antigen. Although its role in the biology and virulence of GBS has not been defined, it is opsonic and capable of eliciting protective immunity. The α C protein is widely distributed among clinical isolates and is a potential protein carrier and antigen in conjugate vaccines to prevent GBS infections. The structural gene for the α C protein, bca, has been cloned and sequenced. The protein encoded by bca is related to a class of surface-associated proteins of Gram-positive cocci involved in virulence and immunity. To investigate the potential roles of the α C protein, bca null mutants were generated in which the bca gene was replaced with a kanamycin resistance cassette via homologous recombination using a novel shuttle/suicide vector. Studies of lethality in neonatal mice showed that the virulence of the bca null mutants was attenuated 5- to 7-fold when compared with the isogenic wild-type strain A909. Significant differences in mortality occurred in the first 24 h, suggesting that the role of the α antigen is important in the initial stages of the infection. In contrast to A909, bca mutants were no longer killed by polymorphonuclear leukocytes in the presence of α-specific antibodies in an in vitro opsonophagocytic assay. In contrast to previous studies, α antigen expression does not appear to play a role in resistance to opsonophagocytosis in the absence of α-specific antibodies. In addition, antibodies to the α C protein did not passively protect neonatal mice from lethal challenge with bca mutants, suggesting that these epitopes are uniquely present within the α antigen as expressed from the bca gene. Therefore, the α C protein is important in the pathogenesis of GBS infection and is a target for protective immunity in the development of GBS vaccines.
