Suicide behaviours in incarcerated males: Links to psychopathic traits,forms of aggression to others,personal characteristics,and current penitentiary variables

Self-injurious behaviours and suicide attempts among incarcerated people are higher when compared with the general population. The current research is designed to examine the prevalence of self-injurious behaviours and suicide attempts among incarcerated males in Spain, and the factors associated with these behaviours. 201 men imprisoned in Spain completed anonymous self-report measures of demographic variables (e.g., age, marital status), the Triarchic Psychopathy Model (boldness, meanness, and disinhibition) and impulsive/premeditated aggression and aggressive behaviour (including physical, verbal, hostility, and anger). Official records were also consulted for information related to criminality (i.e., prior imprisonment and type of offence). Overall, 37.5% of residents reported having injured themselves at a time of anger or despair and 24.9% reported attempting suicide at any point in their lives. Lower scores in meanness, higher scores on impulsive aggression, serious illnesses and previous imprisonment were associated with an increased risk of self-injurious and/or suicide attempting behaviours. Being married acted as a protective factor of attempting suicide. Trait variables related to psychopathy (lower meanness) and aggression (higher impulsive aggression) were associated with increased frequency of suicide attempts in prisoners even after controlling for personal and criminal variables. The prevention of high rates of suicide in prisons needs the treatment of those cognitive variables in addition to more contextual personal and criminal variables.

Personality traits affect the influences of intensity perception and emotional responses on hedonic rating and preference rank toward basic taste solutions

This study aimed at determining, based on independent predictors of taste intensity and emotional response, whether individual personality traits could affect prediction models of overall liking and preference rank toward basic taste solutions. Sixty-seven participants rated taste intensities (TI) of four basic-taste solutions at both low and high concentrations, and of plain water. Emotional responses toward each sample were measured using a self-reported emotion questionnaire (SE), facial expressions (FE), and/or autonomic nervous system responses (ANS). Participants rated overall liking of the samples and ranked their preferences. Based on the results of a hierarchical cluster analysis of five personality traits measured using the Big Five Inventory, participants were classified into two clusters: cluster N (high neuroticism) and cluster E (high extraversion). Results showed that the SE measure for both clusters N and E was better than the TI, FE, and ANS measures in explaining variances of overall liking or preference rank. A measurement of effect size found that using FE and/or taste intensity measures, along with self-reported emotion measure, could enhance model predictability of overall liking or preference rank toward taste samples for cluster N, while the contribution to the prediction model for cluster E was minimal. ANS measures showed little contribution to the prediction model of overall liking for either cluster. In conclusion, this study shows that personality traits, in particular traits of extraversion and neuroticism, affect not only optimum measures of emotional responses, but also modulate predicting overall liking and preference rank toward basic taste solutions.     

Insights from examination of hearts from adults dying suddenly to the understanding of congenital cardiac malformations

Congenital heart disease is a rare but important finding in adults who experience sudden death. Examination of the congenitally malformed heart has historically been considered esoteric and best left to those with expertise. The Cardiac Risk in the Young cardiovascular pathology laboratory based at St George's University of London has now received over 6,000 cases. Of these, 21 congenitally malformed hearts were retained for research and educational purposes. Hearts were assessed using sequential segmental analysis, and causes of death were adjudicated based on thorough macroscopic examination and histology. Congenital malformations that were encountered included atrial septal defects, ventricular septal defects, tetralogy of Fallot, and transposition of the great arteries in both its regular and congenitally corrected variants. Findings also included hearts with mirror-imaged and isomeric atrial appendages. Direct causes of death included myocardial fibrosis, pulmonary hypertension, and hemorrhage. A small but notable proportion did not reveal a substrate for arrhythmia, raising the question of whether the terminal event was due to the congenital heart disease itself, or an underlying channelopathy. Here, we demonstrate the value of simple sequential segmental analysis in describing and categorizing the cases, with the concept of the “morphological method” serving to identify the distinguishing features of the cardiac components.

壮药材滇桂艾纳香及其易混品种东风草和高艾纳香比较研究

目的： 建立壮药材滇桂艾纳香专属性检验方法。方法： 采用基原鉴别、性状鉴别、显微鉴别、薄层鉴别、分子生物学及特征图谱等方法对滇桂艾纳香及其易混品种东风草和高艾纳香进行对比研究。结果： 三者的根、茎、叶性状基本相同，区别点在于滇桂艾纳香头状花序小（直径0.5~0.8 cm），东风草头状花序大（直径1.5~2 cm），高艾纳香头状花序具密集的长绒毛；三者的根、茎横切面，粉末显微特征基本相同，高艾纳香具基部膨大的非腺毛；薄层鉴别（1）中高艾纳香比滇桂艾纳香和东风草少1个斑点；薄层鉴别（2）中滇桂艾纳香比东风草和高艾纳香少1个特征斑点；ITS2序列N-J树聚类分析显示三者具有良好的单系性，三者种间最小遗传距离均大于种内最大遗传距离；与滇桂艾纳香对照图谱相比，东风草平均相似度为0.962，高艾纳香平均相似度仅为0.789。结论： 高艾纳香与滇桂艾纳香区别较大，不宜混用，在日常使用中应注意甄别；东风草与滇桂艾纳香在性状、显微、薄层、分子生物学、特征图谱等方面相似度较高，在对二者进行充分的药理活性以及临床试验等基础上，可考虑作为滇桂艾纳香的替代品使用，以缓解药用资源不足的问题。

Is personality associated with dementia risk? A meta-analytic investigation

This study provides a quantitative synthesis of the prospective associations between personality traits (neuroticism, extraversion, openness, agreeableness, conscientiousness) and the risk of incident Alzheimer’s disease and related dementias. We conducted five separate meta-analyses with 8–12 samples (N = 30,036 to 33,054) that were identified through a systematic literature search following the MOOSE guidelines. Higher neuroticism (HR = 1.24, 95% CI [1.17, 1.31]) and lower conscientiousness (HR = 0.77, 95% CI [0.73, 0.81]) were associated with increased dementia risk, even after accounting for covariates such as depressive symptoms. Lower extraversion (HR = 0.92, 95% CI [0.86, 0.97]), openness (HR = 0.91, 95% CI [0.86, 0.96]), and agreeableness (HR = 0.90, 95% CI [0.83, 0.98]) were also associated with increased risk, but these associations were less robust and not significant in fully adjusted models. No evidence of publication bias was found. The strength of associations was unrelated to publication year (i.e., no evidence of winner’s curse). Meta-regressions indicated consistent effects for neuroticism, openness, and conscientiousness across methods to assess dementia, dementia type, follow-up length, sample age, minority, country, and personality measures. The association of extraversion and agreeableness varied by country. Our findings indicate robust associations of neuroticism and conscientiousness with dementia risk.
