Heart rate (HR) and electrodermal activity (EDA) are often used as physiological measures of psychological arousal in various neuropsychology experiments. In this exploratory study, we analyze HR and EDA data collected from four participants, each with a history of suicidal tendencies, during a cognitive task known as the Paced Auditory Serial Addition Test (PASAT). A central aim of this investigation is to guide future research by assessing heterogeneity in the population of individuals with suicidal tendencies...

Major Depressive Disorder (MDD) is a serious mental disorder that if untreated not only affects physical health but also has a high risk of suicide. While the neurophysiological phenomena that contribute to the formation of Suicidal Ideation (SI) are still ill-defined, clear links between MDD and cardiovascular disease have been reported. The aim of this study is to extract suitable features from arterial pulse signals with a view to predicting SI within MDD and control groups. Sixteen unmedicated MDD patients with a history of SI (MDDSI+), sixteen without SI (MDDSI-) and twenty-nine healthy subjects (CONT) were recruited at a psychiatric clinic in the UAE...

In addition to dealing with the normal challenges of being a teenager, many times LGBTQ youth have to deal with harassment, intimidation, and bullying on a daily basis as they disproportionately experience verbal and physical harassment while in school as a result of their sexual orientation and/or gender identity. This violence adversely affects these students' health and well-being as reflected in the depression and suicide rate among LGBTQ youth. As Part 2 of a series in articles on caring for LGBTQ youth in a school setting, this article reviews specific health risks in this group of students...

This study investigated whether personality traits, psychopathological characteristics, and sociodemographic factors in depressed patients differentiate patients with only suicidal thoughts from those who have attempted suicide. We investigated two groups of patients with an affective disorder: 198 patients with a suicide attempt within the last 3 months (sex ratio male to female, 1:1.3; mean age male to female, 44.8/44.7 years) and 30 patients without a suicide attempt but with suicidal thoughts (sex ratio male to female, 1:2; mean age male to female, 39...

Behavioural addictions concern behaviour which generate pleasure (shopping, gambling, sex, etc.). Pathological gambling is the most common behavioural addiction in elderly people. It can be severely harmful causing psychological, financial and family problems and increasing the risk of suicide. Gambling addiction is underestimated in the elderly. Psychological, social and family support is important whatever the age, with treatment aiming to improve the person's quality of life, help them regain control of their gambling or stop altogether...

OBJECTIVE: To examine the relationship of negative emotions with suicidal ideation during 12 weeks of Problem Adaptation Therapy (PATH) versus Supportive Therapy of Cognitively Impaired Older Adults (ST-CI), hypothesizing that improved negative emotions are associated with reduced suicidal ideation, PATH improves negative emotions more than ST-CI, and improved negative emotions, rather than other depression symptoms, predict reduction in suicidal ideation. METHODS: In a randomized controlled trial of two home-delivered psychosocial interventions, 74 older participants (65-95 years old) with major depressive disorder and cognitive impairment were recruited in collaboration with community agencies...

BACKGROUND/AIMS: Tumor cell proliferation is modified by 1,25-Dihydroxy-Vitamin D3 (1,25(OH)2D3), a steroid hormone predominantly known for its role in calcium and phosphorus metabolism. Key properties of tumor cells include enhanced glycolytic flux with excessive consumption of glucose and formation of lactate. As glycolysis is highly sensitive to cytosolic pH, maintenance of glycolysis requires export of H+ ions and lactate, which is in part accomplished by Na+/H+ exchangers, such as NHE1 and monocarboxylate transporters, such as MCT4...

BACKGROUND/AIMS: The thaliana phytoalexin Camalexin has been proposed for the treatment of malignancy. Camalexin counteracts tumor growth in part by stimulation of suicidal death or apoptosis of tumor cells. Similar to apoptosis of nucleated cells, erythrocytes may enter suicidal death or eryptosis, which is characterized by cell shrinkage and cell membrane scrambling with phosphatidylserine translocation to the erythrocyte surface. Cellular mechanisms contributing to the complex machinery executing eryptosis include increase of cytosolic Ca2+ activity ([Ca2+]i), oxidative stress, ceramide, protein kinase C and caspases...

Gender and ethnicity are significant factors when evaluating suicidal risk, especially among ethnically diverse populations. In the current study we explored the association between gender, ethnicity, and suicide ideation and attempts among Arab and Jewish vocational education and training high school students in Israel. Students (N = 3,554) completed a self-report survey evaluating suicide ideation and attempts, depression, anxiety, somatization, and sense of belonging. Hierarchical generalized linear modeling indicated that female Arab adolescents had elevated levels of suicide ideation, higher rates of suicide attempts, and greater psychological distress than Arab males and Jewish students...

Suicide is a global public health problem, and with recent economic and societal changes, there may be emerging risk factors unrecognized by health care professionals. The aim of this systematic review was to update existing suicide risk factor literature applicable to emergency health care settings. A total of 35 articles identified from PsycINFO, CINAHL, and Medline met the inclusion criteria. Results supported the significance of existing suicide risk factors and identified emerging risk factors. The review provides a high-quality update of risk factor literature that could be applied to emergency health care settings; however, further research is needed to confirm emerging risk factors...

In addition to physical barriers, neutrophils are considered a part of the first line of immune defense. They can be found in the bloodstream, with a lifespan of 6-8 h, and in tissue, where they can last up to 7 days. The mechanisms that neutrophils utilize for host defense are phagocytosis, degranulation, cytokine production, and, the most recently described, neutrophil extracellular trap (NET) production. NETs are DNA structures released due to chromatin decondensation and spreading, and they thus occupy three to five times the volume of condensed chromatin...

Non-Suicidal Self-Injury (NSSI) is a common, multifaceted phenomenon among adolescents. Recent researchers have shown that a number of psychological and psychiatric correlates are implicated in the onset/repetition of NSSI, but those previous studies did not directly observe the family interaction patterns of this clinical population. In this paper, the quality of family interactions was observed using the Lausanne Trilogue Play procedure to deepen the specific interactive dimensions associated with NSSI in adolescents...

Prior to the mid-1980s, suicide in Indigenous population in Northwestern Ontario, Canada, was rare, occurring at rates of 1-2 per year among over 20 communities. By the early 1990s, the completed suicide rates in the same communities were among the highest in the world. Prior to the outbreak of the suicide epidemic, sniffing of gasoline containing tetraethyl was common in many communities. Existing literature confirms that tetraethyl lead poisoning is associated with alterations to the amyloid-β protein precursor and amyloid-β as well as the 5-HT-1B receptor...

One in five young adults are diagnosed with a mental illness and many experience psychological distress during their first year of college due to new pressures in academia. The purpose of the current integrative review was to describe and synthesize hope and mental health in young adults in college. PubMed, CINAHL, and PsycINFO were searched for articles published in peer-reviewed journals from 2011-2016. Twenty empirical works were selected for inclusion and five themes emerged: (a) Hope is Associated With Improved Coping, (b) Hope is Associated With Improved Well-Being, (c) Hope is a Moderator Between Depression and Negative Life Events, (d) Hope is a Protective Factor in Suicide, and (e) Hope is a Factor in Healthy Behavior Engagement...
