Article Synopsis
  • Black and Hispanic older adults have a higher risk of developing Alzheimer's disease and dementia compared to White adults, but the reasons behind these disparities are not fully understood.
  • A study involving over 1.5 million older Veterans found that Black Veterans had a 65% higher risk and Hispanic Veterans had a 50% higher risk of developing dementia compared to White Veterans, even after adjusting for age and sex.
  • The research concluded that social determinants of health and cardiovascular disease are significant factors contributing to these disparities, suggesting they could be potential targets for interventions to help reduce the risk of dementia in these populations.

Homeless veterans are likely to experience Post Traumatic Stress Disorder (PTSD). Homelessness itself is traumatic, and PTSD may exacerbate homelessness risk for veterans. Often, PTSD goes untreated in this subpopulation of veterans.

Background: Social workers (SWs) and chaplains are trained to support families facing challenges associated with critical illness and potential end-of-life issues. Little is known about how parents view SW/chaplain involvement in care for critically ill children with cancer.

Methods: We studied parent perceptions of SW/chaplain involvement in care for pediatric intensive care unit (PICU) patients with cancer or who had a hematopoietic cell transplant.

Aims: Contemporary theories of attention-deficit/hyperactivity disorder (ADHD) and alcohol use disorder (AUD) emphasize core dysfunctions in reward-related processes and behaviors as pathognomonic characteristics. However, to date, it is unclear which domains of reward functioning are unique to ADHD versus AUD symptom dimensions, and which represent underlying shared correlates.

Methods: The current study employed secondary data analyses from a large community sample of emerging adults (N = 602; 57.

Background: Those with posttraumatic stress disorder (PTSD) have lower overall functioning than healthy controls. However, this population is not homogenous, and those with PTSD have a wide range of functional outcomes. To our knowledge, only one other study has evaluated the predictors of better functioning within patients with PTSD.

Background: Little is known about how decision-making conversations occur during pediatric intensive care unit (PICU) family conferences (FCs).

Objective: Describe the decision-making process and implementation of shared decision making (SDM) during PICU FCs.

Design: Observational study.

Background: The harmful effects of marijuana on health and in particular cardiovascular health are understudied. To develop such knowledge, an efficient method of developing an informative cohort of marijuana users and non-users is needed.

Methods: We identified patients with a diagnosis of coronary artery disease using ICD-9 codes who were seen in the San Francisco VA in 2015.

Stakeholder-developed interventions are needed to support pediatric intensive care unit (PICU) communication and decision-making. Few publications delineate methods and outcomes of stakeholder engagement in research. We describe the process and impact of stakeholder engagement on developing a PICU communication and decision-making support intervention.

Humans naturally and effortlessly use a set of cognitive tools to reason about biological entities and phenomena. Two such tools, essentialist thinking and teleological thinking, appear to be early developmental cognitive defaults, used extensively in childhood and under limited circumstances in adulthood, but prone to reemerge under time pressure or cognitive load. We examine the nature of another such tool: anthropocentric thinking.

A large body of cognitive research has shown that people intuitively and effortlessly reason about the biological world in complex and systematic ways. We addressed two questions about the nature of intuitive biological reasoning: How does intuitive biological thinking change during adolescence and early adulthood? How does increasing biology education influence intuitive biological thinking? To do so, we developed a battery of measures to systematically test three components of intuitive biological thought: anthropocentric thinking, teleological thinking and essentialist thinking, and tested 8th graders and university students (both biology majors, and non-biology majors). Results reveal clear evidence of persistent intuitive reasoning among all populations studied, consistent but surprisingly small differences between 8th graders and college students on measures of intuitive biological thought, and consistent but again surprisingly small influence of increasing biology education on intuitive biological reasoning.
