Body Mass Index Is an Important Predictor for Suicide: Results from a Systematic Review and Meta‐Analysis

Public health concerns for the independent management of obesity and suicidal behavior are rising. Emerging evidence suggests body weight plays an important role in quantifying the risk of suicide. In light of these findings, we aimed to clarify the association between body mass index (BMI) and suicidal behavior by systematically reviewing and evaluating the literature. Studies were identified by searching MEDLINE, EMBASE, PsycINFO, and CINAHL from inception to January 2015, supplemented by hand and grey literature searches. Study screening, data extraction, and risk of bias assessment were conducted in duplicate. We included 38 observational studies. Meta‐analyses supported an inverse association between BMI and completed suicide. Pooled summary estimates demonstrated that underweight was significantly associated with an increased risk of completed suicide (HR = 1.21, 95% CI 1.07 to 1.36, p = .002), and obesity (HR = 0.71, 95% CI 0.56 to 0.89, p = .003) and overweight (HR = 0.78, 95% CI 0.75 to 0.82, p < .0001) were significantly associated with a decreased risk of completed suicide relative to normal weight. A qualitative summary of the literature demonstrated conflicting evidence regarding the association between BMI and attempted suicide and revealed no association between BMI and suicidal ideation. BMI may be used to aid the assessment of suicide risk, especially that of completed suicide. However, unmeasured confounders and systematic biases of individual studies limit the quality of evidence.     

Experiences of surgery readiness assessments in British Columbia

Abstract

Background: A surgical readiness assessment is a major step in the medical journey of trans people seeking gender-affirming surgery. Much of the peer-reviewed literature surrounding surgical readiness assessments emphasizes the perspectives of academics and clinicians, leaving the voices of trans and gender diverse patients largely unheard.

Aims: This paper foregrounds patient experiences with surgery readiness assessments to discuss the tensions, challenges and opportunities they generate.

Methods: We conducted a thematic analysis of 35 in-depth interviews with trans people who accessed or were seeking to access gender-affirming surgery in British Columbia.

Results: We developed three main themes to capture participants’ narratives of their surgical assessment experiences. The first, assessments as gatekeeping, explores the stories of people who described their assessments as outdated and even discriminatory processes. The second, assessments as a barrier to care, discusses the informational missteps, bureaucratic regulations, economic issues, and geographic concerns that made assessments difficult to access. The third, assessments as useful, includes positive stories about assessments that often involved feeling supported by an assessor and feeling prepared for the next steps.

Discussion: These narratives demonstrate how much variation exists among people’s experiences of readiness assessments for gender-affirming surgery. No matter how their actual assessment turned out, many participants approached their appointments with a great deal of anxiety and trepidation. We attributed this stress was to challenges ranging from lengthy wait times, arbitrary medical gatekeeping, a lack of access to knowledgeable and supportive providers, unclear or changing administrative processes, and insufficient communication. To address these challenges, it is crucial for the medical system to create more accessible pathways with centralized, up-to-date information for people trying to access assessments. Patients are best served by multi-disciplinary gender-affirming teams that provide individualized care.     

Children's kinematic false memories

ABSTRACT

Individuals misrecognise as seen the never-presented natural continuation of an action. These false memories derive from the running of kinematic mental models of the actions seen, which rest on motor inferences from implicit knowledge. We verified an implied prediction: kinematic false memories should be detectable even in children. The participants in our experiments first observed photos in which actors were about to perform actions on objects. At recognition they were presented with the original photos, plus (a) distractors representing the unseen natural continuation of the original actions, (b) distractors representing the beginning of other actions on the same objects and (c) distractors representing completed different actions on the same objects. In contrast to the original studies in which participants expressed their confidence in recognition, in our experiments the participants catgorirzed the action as seen or not seen. After replicating the original results with the dichotomous recognition task (Experiment 1), we detected spontaneous false memories also in children (Experiment 2).     

Mild Traumatic Brain Injury and Posttraumatic Stress Disorder in Returning Iraq and Afghanistan War Veterans: Implications for Assessment and Diagnosis

Mild traumatic brain injury (MTBI) and posttraumatic stress disorder (PTSD) are considered the “signature injuries” of combat soldiers returning from Iraq and Afghanistan. Both disorders can greatly affect the functioning of soldiers, yet the disorders often go undetected or are misdiagnosed by both military and civilian health care providers. This article provides information about MTBI and PTSD in returning combat soldiers along with implications for assessment and diagnosis.
