Paternal behavior in captive fat-tailed dwarf lemurs (Cheirogaleus medius) is preserved under socially relevant conditions.

Fat-tailed dwarf lemurs (Cheirogaleus medius), primates endemic to Madagascar, are obligate hibernators that form stable, lifelong pairs in the wild. Given the temporal constraints imposed by seasonal hibernation, infant dwarf lemurs must grow, develop, and wean within the first two months of life. Maternal as well as paternal infant care, observed in the wild, has been deemed critical for infant survival.

Restructuring Structural Heart Disease Practice During the COVID-19 Pandemic: JACC Review Topic of the Week.

Patients with structural heart disease are at increased risk of adverse outcomes from the coronavirus disease-2019 (COVID-19) due to advanced age and comorbidity. In the midst of a global pandemic of a novel infectious disease, reality-based considerations comprise an important starting point for formulating clinical management pathways. The aims of these "crisis-driven" recommendations are: 1) to ensure appropriate and timely treatment of structural heart disease patients; 2) to minimize the risk of COVID-19 exposure to patients and health care workers; and 3) to limit resource utilization under conditions of constraint.

The importance of the DSM-IV E and F criteria in self-report assessments of PTSD.

The purpose of the current study was to examine the DSM-IV E and F criteria when using self-report measures of Posttraumatic Stress Disorder (PTSD). According to DSM-IV there are six core criteria required for a PTSD diagnosis including specific trauma characteristics, re-experiencing, avoidance, hyperarousal, duration, and impairment level. The Impact of Events Scale (IES) is a widely used self-report measure designed to measure PTSD symptoms.

PTSD symptoms and dominant emotional response to a traumatic event:an examination of DSM-IV Criterion A2.

To qualify for a diagnosis of posttraumatic stress disorder (PTSD), the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) requires that individuals report experiencing dominant emotions of fear, helplessness, and horror during the trauma (Criterion A2). Despite this stipulation, traumatic events can elicit a myriad of emotions other than fear, such as anger, guilt or shame, sadness, and numbing. The present study examined which emotional reactions to a stressful event in a college student sample are associated with the highest levels of PTSD symptoms.
