Hands-Only Cardiopulmonary Resuscitation Education: A Comparison of On-Screen With Compression Feedback, Classroom, and Video Education.

Study Objective: We compare 3 methods of hands-only cardiopulmonary resuscitation (CPR) education, using performance scores. A paucity of research exists on the comparative effectiveness of different types of hands-only CPR education. This study also includes a novel kiosk approach that has not previously been studied, to our knowledge.

A novel educational outreach approach to teach Hands-Only Cardiopulmonary Resuscitation to the public.

Review: The American Heart Association set goals in 2010 to train 20 million people annually in cardiopulmonary resuscitation and to double bystander response by 2020. These ambitious goals are difficult to achieve without new approaches.

Methods: The main objective is to evaluate a new approach to cardiopulmonary resuscitation instruction using a self-instructional kiosk to teach Hands-Only CPR to people at a busy international airport.

Part 2: Evidence Evaluation and Management of Conflicts of Interest: 2015 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations.

The process for evaluating the resuscitation science has evolved considerably over the past 2 decades. The current process, which incorporates the use of the GRADE methodology, culminated in the 2015 CoSTR publication, which in turn will inform the international resuscitation councils’ guideline development processes. Over the next few years, the process will continue to evolve as ILCOR moves toward a more continuous evaluation of the resuscitation science.

Sexually dimorphic role of G protein-coupled estrogen receptor (GPER) in modulating energy homeostasis.

This article is part of a Special Issue "Energy Balance". The classical estrogen receptors, estrogen receptor-α and estrogen receptor-β are well established in the regulation of body weight and energy homeostasis in both male and female mice, whereas, the role for G protein-coupled estrogen receptor 1 (GPER) as a modulator of energy homeostasis remains controversial. This study sought to determine whether gene deletion of GPER (GPER KO) alters body weight, body adiposity, food intake, and energy homeostasis in both males and females.

The sexually dimorphic role of adipose and adipocyte estrogen receptors in modulating adipose tissue expansion, inflammation, and fibrosis.

Our data demonstrate that estrogens, estrogen receptor-α (ERα), and estrogen receptor-β (ERβ) regulate adipose tissue distribution, inflammation, fibrosis, and glucose homeostasis, by determining that αERKO mice have increased adipose tissue inflammation and fibrosis prior to obesity onset. Selective deletion of adipose tissue ERα in adult mice using a novel viral vector technology recapitulated the findings in the total body ERα null mice. Generation of a novel mouse model, lacking ERα specifically from adipocytes (AdipoERα), demonstrated increased markers of fibrosis and inflammation, especially in the males.

Distinct hypothalamic neurons mediate estrogenic effects on energy homeostasis and reproduction.

Estrogens regulate body weight and reproduction primarily through actions on estrogen receptor-α (ERα). However, ERα-expressing cells mediating these effects are not identified. We demonstrate that brain-specific deletion of ERα in female mice causes abdominal obesity stemming from both hyperphagia and hypometabolism.

Tropomyosin-related kinase B in the mesolimbic dopamine system: region-specific effects on cocaine reward.

Background: Previous studies found that brain-derived neurotrophic factor (BDNF) derived from nucleus accumbens (NAc) neurons can mediate persistent behavioral changes that contribute to cocaine addiction.

Methods: To further investigate BDNF signaling in the mesolimbic dopamine system, we analyzed tropomyosin-related kinase B (TrkB) messenger RNA (mRNA) and protein changes in the NAc and ventral tegmental area (VTA) in rats following 3 weeks of cocaine self-administration. To study the role of BDNF-TrkB activity in the VTA and NAc in cocaine reward, we used localized viral-mediated Cre recombinase expression in floxed BDNF and floxed TrkB mice to knockdown BDNF or TrkB in the VTA and NAc in cocaine place conditioning tests and TrkB in the NAc in cocaine self-administration tests.
