Loneliness and negative life events as predictors of hopelessness and suicidal behaviors in hispanics: evidence for a diathesis-stress model
In the present study, we examined loneliness and negative life events as predictors of suicide risk (viz., hopelessness and suicidal behaviors) in a sample of 160 Hispanic adults. Consistent with expectations, we found loneliness and negative life events to be positively associated with both hopelessness and suicidal behaviors. In addition, results of conducting hierarchical regression analyses indicated that loneliness accounted for significant amounts of variance in both measures of suicide risk, ranging from 24% to 29% of the variance. The inclusion of negative life events as a predictor was found to account for additional unique variance in hopelessness (3%), but not in suicidal behaviors, beyond what was predicted by loneliness. Finally, consistent with a diathesis-stress model, the Loneliness × Negative Life Events interaction was found to account for an additional 3% of the variance in both suicide risk measures. Implications of the present findings for future research on suicide risk in Hispanics are discussed. © 2010 Wiley Periodicals, Inc.

Altered Motoneuron Properties Contribute to Motor Deficits in a Rabbit Hypoxia-Ischemia Model of Cerebral Palsy
Cerebral palsy (CP) is caused by a variety of factors attributed to early brain damage, resulting in permanently impaired motor control, marked by weakness and muscle stiffness. To find out if altered physiology of spinal motoneurons (MNs) could contribute to movement deficits, we performed whole-cell patch-clamp in neonatal rabbit spinal cord slices after developmental injury at 79% gestation. After preterm hypoxia-ischemia (HI), rabbits are born with motor deficits consistent with a spastic phenotype including hypertonia and hyperreflexia. There is a range in severity, thus kits are classified as severely affected, mildly affected, or unaffected based on modified Ashworth scores and other behavioral tests. At postnatal day (P)0–5, we recorded electrophysiological parameters of 40 MNs in transverse spinal cord slices using whole-cell patch-clamp. We found significant differences between groups (severe, mild, unaffected and sham control MNs). Severe HI MNs showed more sustained firing patterns, depolarized resting membrane potential, and fired action potentials at a higher frequency. These properties could contribute to muscle stiffness, a hallmark of spastic CP. Interestingly altered persistent inward currents (PICs) and morphology in severe HI MNs would dampen excitability (depolarized PIC onset and increased dendritic length). In summary, changes we observed in spinal MN physiology likely contribute to the severity of the phenotype, and therapeutic strategies for CP could target the excitability of spinal MNs

A systematic review of mental disorder, suicide, and deliberate self harm in lesbian, gay and bisexual people
Background: Lesbian, gay and bisexual (LGB) people may be at higher risk of mental disorders than heterosexual people.Method: We conducted a systematic review and meta-analysis of the prevalence of mental disorder, substance misuse, suicide, suicidal ideation and deliberate self harm in LGB people. We searched Medline, Embase, PsycInfo, Cinahl, the Cochrane Library Database, the Web of Knowledge, the Applied Social Sciences Index and Abstracts, the International Bibliography of the Social Sciences, Sociological Abstracts, the Campbell Collaboration and grey literature databases for articles published January 1966 to April 2005. We also used Google and Google Scholar and contacted authors where necessary. We searched all terms related to homosexual, lesbian and bisexual people and all terms related to mental disorders, suicide, and deliberate self harm. We included papers on population based studies which contained concurrent heterosexual comparison groups and valid definition of sexual orientation and mental health outcomes.Results: Of 13706 papers identified, 476 were initially selected and 28 (25 studies) met inclusion criteria. Only one study met all our four quality criteria and seven met three of these criteria. Data was extracted on 214,344 heterosexual and 11,971 non heterosexual people. Meta-analyses revealed a two fold excess in suicide attempts in lesbian, gay and bisexual people [ pooled risk ratio for lifetime risk 2.47 (CI 1.87, 3.28)]. The risk for depression and anxiety disorders (over a period of 12 months or a lifetime) on meta-analyses were at least 1.5 times higher in lesbian, gay and bisexual people (RR range 1.54-2.58) and alcohol and other substance dependence over 12 months was also 1.5 times higher (RR range 1.51-4.00). Results were similar in both sexes but meta analyses revealed that lesbian and bisexual women were particularly at risk of substance dependence (alcohol 12 months: RR 4.00, CI 2.85, 5.61; drug dependence: RR 3.50, CI 1.87, 6.53; any substance use disorder RR 3.42, CI 1.97-5.92), while lifetime prevalence of suicide attempt was especially high in gay and bisexual men (RR 4.28, CI 2.32, 7.88).Conclusion: LGB people are at higher risk of mental disorder, suicidal ideation, substance misuse, and deliberate self harm than heterosexual people
This Corrosion: A systematic Review of the Association between Alternative Subcultures and the Risk of Self-Harm and Suicide
Background: Rates of self-harm and suicide are increasing in young people. The literature suggests that individuals who identify with alternative subcultures (e.g. Goth) may be at a greater risk. Objective: To explore the prevalence of self-harm and suicide in alternative subcultures and the factors that might contribute to this increased risk. Method: Using a systematic strategy, the databases PsycINFO, Scopus, MEDLINE and Web of Science and the E-Thesis online service (ETHOS) were searched for English language only papers, with no restrictions in terms of date of publication. Papers were selected that included data on the relationship between either alternative subculture identity (e.g. Goth) or preference for alternative music (e.g. Heavy Metal) and self-harm or suicide. Ten quantitative papers were included; seven cross-sectional, two longitudinal and one cross-sectional state level comparison study. Two qualitative papers were also included. Studies were assessed by two reviewers for risk of bias Results: The findings indicated that individuals who associated with alternative subcultures were at a greater risk of self-harm and suicide. Whilst qualitative papers identified potential mechanisms (e.g. exposure to self-harm and the way self-harm is presented or normalised) there remains limited support for these mechanisms. Conclusions: More research is required to understand the association between self-harm, suicide and alternative subculture affiliation, and the factors underlying it. Longitudinal studies and studies focusing on mechanism are particularly important
