Mom-it helps when youre right here! Attenuation of neural stress markers in anxious youths whose caregivers are present during fMRI.

Close proximity to an attachment figure, such as a caregiver, has been shown to attenuate threat-related activity in limbic regions such as the hypothalamus in healthy individuals. We hypothesized that such features might be similarly attenuated by proximity during a potentially stressful situation in a clinically anxious population of youths. Confirmation of this hypothesis could support the role of attachment figures in the management of anxiety among children and adolescents. Three groups were analyzed: anxious children and adolescents who requested that their caregiver accompany them in the scanner room, anxious children and adolescents without their caregiver in the scanner room and healthy controls (each of N = 10). The groups were matched for age and, among the two anxious groups, for diagnosis (mean age 9.5). The children and adolescents were exposed to physical threat words during an fMRI assessment. Results indicate that activity in the hypothalamus, ventromedial, and ventrolateral prefrontal cortex were significantly reduced in anxious children and adolescents who requested that their caregiver accompany them in the scanner room compared to those without their caregiver in the scanner room. Mean activity in these regions in anxious children and adolescents with their caregiver in the scanner room was comparable to that of healthy controls. These data suggest links between social contact and neural mechanisms of emotional reactivity; specifically, presence of caregivers moderates the increase in anxiety seen with stressful stimuli. Capitalizing on the ability of anxious youths to manifest low levels of anxiety-like information processing in the presence of a caregiver could help in modeling adaptive function in behavioral treatments

Ischemic Preconditioning Does Not Improve Time Trial Performance in Recreational Runners

International Journal of Exercise Science 13(6): 1402-1417, 2020. Some evidence indicates that ischemic preconditioning (IPC) may positively affect endurance exercise performance, but IPC’s effect on running performance is unclear. This study’s purpose was to examine the effect of IPC on running performance in recreational runners. Participants (n=12) completed IPC, a sham (SH) condition, and a leg elevation without blood restriction (LE) control condition on separate days (order randomized). For IPC, blood was restricted using blood pressure cuffs inflated to 220 mmHg at the thigh. For SH, the cuffs were inflated to only 20 mmHg. For LE, participants positioned their legs at 90 degrees against a wall while laying supine. The duration of each protocol was 30 minutes (three 5-minute bouts with 5-minute breaks). Following each protocol, participants ran 2.4 kilometers as fast as possible on a motorized treadmill. Run time, heart rate, and perceived exertion were measured and statistically compared, using repeated-measures ANOVA, each 0.8 kilometers. There were no differences in heart rate or time trial performance across protocols (p\u3e0.05; IPC, 612.5±61.2 sec; SH, 608.1±57.9 sec; LE, 612.7±59.1 sec). Rating of perceived exertion at 0.8 kilometers was significantly lower for the IPC protocol than SH in females only (~5.7%, or ~0.8 points on a 6-20 scale; p\u3c0.05). Our IPC protocol did not improve running performance or physiological parameters during a time trial run in recreational runners. The performance benefit seen in this study’s most fit individuals suggests that fitness level may influence IPC’s efficacy for improving endurance running performance

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Animal Portrayal in the Media

The purpose of this study is to determine how animal rights and conservation are portrayed in news media, particularly in magazines. Additionally, this study seeks to uncover how portrayal of these topics has evolved over the past 25 years, and whether or not the spread of the conservation movement has affected the content of either magazine. By conducting a content analysis of the magazines Discover and National Geographic, the study will gather data from articles regarding coverage of animals, wildlife, and the conservation movement, analyzing how these things are portrayed and how coverage changes over time. The study will reveal how wild and domestic animals are covered, how prominently their rights are featured in articles, and the differences in coverage of these topics between the two magazines. The study will also examine the effects of different animals when interacting with humans in different environments, especially through the transmission of particular diseases

Centering Culture in Mental Health: Differences in Diagnosis, Treatment, and Access to Care Among Older People of Color

Mental healthcare disparities are routinely documented, yet they remain wider than in most other areas of healthcare services and common mental disorders (depression and anxiety) continue to be one of the highest health burdens for older people of color. To address disparities in mental health services for older people of color, the narrative must move beyond simply documenting these inequities and attain a better understanding of the internalized, interpersonal, systemic, and medical racism that have harmed these communities and excluded them from its services in the first place. It is imperative that researchers, clinicians, and policymakers acknowledge the realities of racism and discrimination as leading causes of mental healthcare disparities. Therefore, this review is a call-to-action. Authors adopt an antiracist and health equity lens in evaluating the differing needs of Blacks/African-Americans, Asian Americans, and Latinos by exploring psychiatric comorbidity, experiences with seeking, accessing, and engaging in treatment, and the unique cultural and psychosocial factors that affect treatment outcomes for these diverse groups. Further, authors offer researchers and practitioners tangible tools for developing and implementing culturally-sensitive, mental health focused interventions for older people of color with special attention placed on cultural adaptations, models of care, prevention, and practical strategies that can be implemented to reduce disparities and increase equity in mental healthcare
