Suicide by abdominal wounds suggesting seppuku: Case reports from Romania and an international literature review

Suicide by abdominal wounds suggesting seppuku: Case reports from Romania and an international literature review. Claudia Judea-Pusta, Alexandru Rusu, Andreea Camarasan. Aggression and Violent Behavior, Volume 47, July–August 2019, Pages 68-73. https://doi.org/10.1016/j.avb.2019.03.006

Highlights
•    In Romania this type of suicide is rarely practiced, commonly seen in older males.
•    Frequently the victims suffer from a mental illness, or are alcohol users.
•    The tool used is the knife; the lesions are located in the middle abdominal axis.
•    The mortality rate is higher in cases of abdominal wounds suggesting seppuku.
•    It is important to establish a differential diagnosis between suicide and homicide.

Abstract: Seppuku is a traditional suicide method practiced by honorable Japanese samurai. Today this method of suicide is rarely used in Japan or worldwide and may be exceptionally encountered in patients suffering from psychiatric disorders, the majority of them being older men. It is well known that clinical and cultural factors also play a role in practicing this method of suicide. The mortality rate is significantly higher in cases of abdominal wounds suggesting seppuku, compared to the mortality rate caused by simple stab wounds. Death can occur immediately through massive external or/and internal hemorrhage as well as later on through complications, often septic. In the Romanian forensic literature files, suicide by abdominal stabbing suggesting seppuku is rarely encountered and documented. When investigating violent deaths owing to sharp force, the role of the forensic pathologist is not only to establish the cause of death and the mechanism used for creating the lesions, but also to identify the object used for inflicting the injuries, the type of the injuries, allowing thus to formulate a conclusion from legal perspective upon the act itself: suicide or homicide? The present paper reviews the international literature and presents three cases of suicide by self- inflected abdominal stab wounds suggesting seppuku, autopsied at the Bihor County Forensic Service, Romania, during 2013–2017.


The role of media exposure on relational aggression: Exposure to relational aggression has the strongest effect on subsequent relational aggression; these results support cross-over effect

The role of media exposure on relational aggression: A meta-analysis. Nicole Martins, Andrew Weaver. Aggression and Violent Behavior, Volume 47, July–August 2019, Pages 90-99. https://doi.org/10.1016/j.avb.2019.03.001

Highlights
•    Exposure to relational aggression has the strongest effect on subsequent relational aggression
•    Exposure to non-specific media content has the weakest effect on relational aggression
•    Exposure to physical aggression fell in the middle of the two content types; supports cross-over effect
•    Future research should study these issues among heterogeneous populations so moderating variables can be further examined.

Abstract: We conducted a meta-analysis of 33 studies that examined the effects of media exposure on relationally aggressive behaviors and cognitions (a total of 66 effect sizes, N = (20,990). Across all types of aggressive content, there was a small positive effect (r = 0.15) on relational aggression. However, a comparison of effects sizes demonstrate that exposure to relational aggression had the strongest effect (r = 0.21), whereas exposure to non-specific media content had the weakest effect (r = 0.08). Exposure to physical aggression fell in the middle of the two content types (r = 0.15). Potential explanations for these effects as well as moderators that could influence the results are considered, and the practical implications of these findings are discussed.

Homicide and suicide appear to be more prevalent in democracies

Government political structure and violent death rates: A longitudinal analysis of forty-three countries, 1960–2008. PhillipMarotta et al. Aggression and Violent Behavior, August 8 2019. https://doi.org/10.1016/j.avb.2019.07.008

Abstract
Objectives: Currently, little is known regarding the effect of regime type on mortality on a global level. The purpose of this study is to examine the effect of regime type on the rates of violent deaths (homicide, suicide, and combined rates).

Methods: Three measures of democracy were used to quantify regime type, the independent variable. Homicide and suicide rates were obtained from the World Health Organization. Multivariate conditional fixed-effects models were run to examine associations between regime characteristics and logged rates of homicide, suicide, and violent deaths. Models were adjusted for unemployment and economic inequality.

Results: Nations that scored higher on democracy indices, especially emerging democracies, experienced increased mortality due to violence. Homicide and suicide were divergent, showing a different time course and decreasing statistical power as a combined variable. Unemployment and inequality were associated with higher violence-related mortality.

Conclusions: Homicide and suicide appear to be more prevalent in democracies. Future analyses should examine which aspects of democracies lead to higher rates of violent death and should seek to use independently collected mortality data.

From the neuroimaging data, we conclude that we cannot define the content of our thoughts during "mind blanking" because our inner speech system does not work at that time

The neural correlates of “mind blanking”: When the mind goes away. Toshikazu Kawagoe  Keiichi Onoda  Shuhei Yamaguchi. Human Brain Mapping, August 7 2019. https://doi.org/10.1002/hbm.24748

Abstract: Mind blanking (MB) is the state where our minds are seemingly “nowhere,” and attention calls no perceptual input into conscious awareness. It is little investigated, perhaps partly because it is difficult to detect the mysterious periods of blanking. In this study, we found that our participants could intentionally produce a state of MB whose neural correlates were deactivation of Broca's area and parts of the default mode network (namely, the hippocampus) which would be active during mind wandering (MW), in addition to activity in another region in the default mode network (namely, anterior cingulate cortex). Because the behavioral finding replicates a previous report of ours, we suggest that the simple instructions that we used to induce MB should be effective. From the neuroimaging data, we conclude that we cannot define the content of our thoughts during MB because our inner speech system does not work at that time. Another possibility is that we actually think of nothing in the MB state. Although more sophisticated studies would be needed to uncover the mechanism of such a phenomenon, the present study provides a methodology and clues for understanding MB and related concepts such as MW, awareness, and metacognitive ability.

Death anxiety and death acceptance in atheists and other nonbelievers: The more certainty of Atheism, the less fear of death

Death anxiety and death acceptance in atheists and other nonbelievers. Jacob S. Sawyer, Melanie E. Brewster & Melissa M. Ertl. Death Studies, Aug 7 2019. https://doi.org/10.1080/07481187.2019.1648339

Abstract: This study explores how age, certainty of belief, belief in science and gender is related to death anxiety and death acceptance. Results from a sample of atheists and other nonbelievers (N = 270) in the United States suggested that age and certainty of belief were significantly related to death anxiety and death acceptance, while belief in science was not a significant predictor. In addition, women reported higher levels of death anxiety compared to men. Implications and directions for future research in death perspectives for atheists and other nonbelievers are discussed.

Also Monastic Tibetan Buddhists showed significantly greater fear of death than any other group. The monastics were also less generous than other groups about the prospect of giving up a slightly longer life in order to extend the life of another:

Do Relatives With Greater Reproductive Potential Get Help First?: A Test of the Inclusive Fitness Explanation of Kin Altruism

Do Relatives With Greater Reproductive Potential Get Help First?: A Test of the Inclusive Fitness Explanation of Kin Altruism. Jordan Schriver et al. Evolutionary Psychology, August 8, 2019. https://doi.org/10.1177/1474704919867094

Abstract: According to inclusive fitness theory, people are more willing to help those they are genetically related to because relatives share a kin altruism gene and are able to pass it along. We tested this theory by examining the effect of reproductive potential on altruism. Participants read hypothetical scenarios and chose between cousins (Studies 1 and 2) and cousins and friends (Study 3) to help with mundane chores or a life-or-death rescue. In life-or-death situations, participants were more willing to help a cousin preparing to conceive rather than adopt a child (Study 1) and a cousin with high rather than low chance of reproducing (Studies 2 and 3). Patterns in the mundane condition were less consistent. Emotional closeness also contributed to helping intentions (Studies 1 and 2). By experimentally manipulating reproductive potential while controlling for genetic relatedness and emotional closeness, we provide a demonstration of the direct causal effects of reproductive potential on helping intentions, supporting the inclusive fitness explanation of kin altruism.

Aesthetic empowerment through music

Aesthetic empowerment through music. Elvira Brattico, Ulrika VarankaitÄ—. Musicae Scientiae, July 20, 2019. https://doi.org/10.1177/1029864919850606

Abstract: This article describes how aesthetic enjoyment accompanying musical activities can empower individuals in health and disease. First, we explain the biological determinants of music enjoyment and how they can be studied. In doing so, we distinguish between core sensory pleasure and conscious liking, and we illustrate their respective contributions to aesthetic appreciation and expressive interaction with music. Second, we review findings illustrating the long-term impact of listening to favourite music on the brains of healthy musicians as well as on the brains and behaviour of individuals with pathological symptoms. Based on these findings, we propose a set of putative neural mechanisms underlying aesthetic empowerment through music. We also emphasize the importance of considering individual differences in sensitivity to aesthetic experiences of music, as evidenced, for instance, by neuroimaging and imaging genetics studies, drawing the connections between dopamine neurotransmission and dopaminergic genes with the reactivity of music–brain functions.

You’re dead to me! Social estrangements and social transgressions: A high number of estrangements corresponded to high scores on depressive tendencies and anxious attachment as well as low scores on social support

You’re dead to me! The evolutionary psychology of social estrangements and social transgressions. Glenn Geher et al. Current Psychology, August 8 2019. https://link.springer.com/article/10.1007/s12144-019-00381-z

Abstract: In our species, social connections with a broad array of individuals are foundational to success. On the flip side, we have evolved so as to not be exploited by others. This dynamic is the focus of the studies described here. Study 1 examined the psychology of social estrangements. The main prediction was that the number of estrangements one has would be predictive of various adverse psychological outcomes. Using a sample of 315 young adults, we found evidence for this prediction: A high number of estrangements corresponded to high scores on depressive tendencies and anxious attachment as well as low scores on social support. In Study 2, using a between-participants methodology, we manipulated transgression intensity, target of the transgression, and whether an apology was included. 288 young adults participated. Each participant was presented with a set of stimuli representing one level of each of the three independent variables and then provided ratings for several dependent variables, such as how angry and betrayed he or she would feel in the situation. Transgression intensity and target of the transgression had consistent significant effects on the dependent variables in the predicted directions. Presence of an apology generally had little effect. In both Studies 1 and 2, high scores on the Dark Triad predicted the outcomes as well: In Study 1, a high number of estrangements corresponded to high scores on the Dark Triad. In Study 2, high scores on the Dark Triad corresponded to strong negative responses to social transgressions. Implications for the evolutionary psychology of interpersonal relationships are discussed.

Abstract information alone is capable of changing a majority of clinicians’ care decisions; when unadjusted analyses or secondary outcomes are given undue attention in abstracts, the overall appraisal of a paper's contents is altered

Jellison S, Roberts W, Bowers A, et al. Evaluation of spin in abstracts of papers in psychiatry and psychology journals. BMJ Evidence-Based Medicine, August 5 2019, DOI: 10.1136/bmjebm-2019-111176

Introduction
Randomised controlled trials (RCTs) serve as the gold standard in psychiatry. Given the importance of such trials to clinical practice, it is imperative that results be reported objectively.

Researchers are encouraged to conduct studies and report findings according to the highest ethical standards.1 2 This standard means reporting results completely, in accordance with a protocol that outlines primary and secondary endpoints and prespecified subgroups and statistical analyses. However, authors are free to choose how to report or interpret study results. In an abstract, authors may include only the results they want to highlight or the conclusions they wish to draw. These results and conclusions, however, may not accurately summarise the findings of the study. When such a misrepresentation of study results occurs, there is said to be spin. Spin has been defined as, ‘the use of specific reporting strategies, from whatever motive, to highlight that the experimental treatment is beneficial, despite a statistically nonsignificant difference for the primary outcome, or to distract the reader from statistically nonsignificant results’.3 Many practices contribute to spin, including the selective reporting of outcomes,4 5 p-hacking,6 7 inappropriate application of statistical measures like relative risk8 and manipulation of figures or graphs.9 10

Spin in abstracts has recently been discussed in a systematic review.11 Evidence suggests that abstract information alone is capable of changing a majority of clinicians’ care decisions.12 For example, when unadjusted analyses or secondary outcomes are given undue attention in abstracts, readers’ overall appraisal of the contents of a manuscript is altered.13 Additionally, a previous systematic review showed there to be a higher rate of favourable conclusions in industry-funded studies compared with other sponsorships.14

We have evaluated the prevalence of spin in abstracts of RCTs with nonsignificant primary endpoints in the psychology and psychiatry literature and have explored the association between spin and industry funding.
