The Sochi Olympics, Celebration Capitalism and Homonationalist Pride

In July 2013 the Russian government passed two anti-LGBT laws that drew international criticism. Russia’s impending hosting of the 2014 Winter Olympic Games inspired more sustained international attention to these laws than might have otherwise been the case. In this article, we apply the mutually supporting frameworks of queer/trans necropolitics and celebration capitalism to a content analysis of coverage of the Sochi Olympics in the Advocate and Xtra, the leading LGBT publications in the United States and Canada respectively. We contend that the Advocate and Xtra participated in a homonationalist process of manufacturing consent as the USA, Canada, the West in general and the Olympic Games were glorified while issues relating to racism and colonialism in Russia, the USA and Canada were ignored and these geopolitical formations in general were falsely generalized as safe havens for LGBT people. This conclusion is based on two key observations. First, we noted complete silence about racist and ethnic violence in Russia and in the specific site of Sochi in the Advocate and only one (unelaborated) acknowledgement of Sochi as a historical site of ethnic cleansing in Xtra. Second, in spite of the recent expansion of formal citizenship rights for LGBT people, more uniformly in Canada than in the USA, Advocate and Xtra coverage failed to acknowledge the dissonance between American and Canadian governments positioning themselves as LGBT and human rights leaders and the harm these National Security States continue to deliver to racialized, impoverished and gender and sexual minority populations.&nbsp

Gene Correction Reduces Cutaneous Inflammation and Granuloma Formation in Murine X-Linked Chronic Granulomatous Disease

Our laboratory previously demonstrated that X-linked chronic granulomatous disease (X-CGD) mice develop exaggerated inflammatory responses and form granulomas following intradermal challenge with sterile Aspergillus fumigatus (AF) hyphae. In this study, we examined the efficacy of retroviral-mediated gene transfer (RMGT) into X-CGD bone marrow stem cells in preventing this abnormal inflammatory response. Sterile AF or saline was injected subcutaneously into the ears of wild-type, female X-CGD carrier, X-CGD, or X-CGD mice chimeric for varying numbers of either wild-type or RMGT-corrected neutrophils. Intradermal AF induced marked inflammation at both 3 and 30 d in the X-CGD mice, but not in the carriers or the wild-type mice. Similar to wild-type mice, chimeric X-CGD mice with >20% oxidase-positive neutrophils displayed a minimal and self-limited inflammatory response. Inflammation in chimeric (both wild-type and RMGT-corrected) mice with <15% oxidase-positive neutrophils was also improved compared to X-CGD mice, although still abnormal. This is the first evidence that partial correction of NADPH oxidase activity by gene therapy is likely to be beneficial in reducing or preventing the chronic inflammatory complications of CGD patients if sufficient numbers of RMGT-corrected neutrophils are obtained

The microbiome of the gastrointestinal tract of a range-shifting marine herbivorous fish

Globally, marine species\u27 distributions are being modified due to rising ocean temperatures. Increasing evidence suggests a circum-global pattern of poleward extensions in the distributions of many tropical herbivorous species, including the ecologically important rabbitfis

Genetic and Biochemical Evidence That Haploinsufficiency of the Nf1 Tumor Suppressor Gene Modulates Melanocyte and Mast Cell Fates in Vivo

Neurofibromatosis type 1 (NF1) is a common autosomal-dominant disorder characterized by cutaneous neurofibromas infiltrated with large numbers of mast cells, melanocyte hyperplasia, and a predisposition to develop malignant neoplasms. NF1 encodes a GTPase activating protein (GAP) for Ras. Consistent with Knudson's “two hit” model of tumor suppressor genes, leukemias and malignant solid tumors in NF1 patients frequently demonstrate somatic loss of the normal NF1 allele. However, the phenotypic and biochemical consequences of heterozygous inactivation of Nf1 are largely unknown. Recently neurofibromin, the protein encoded by NF1, was shown to negatively regulate Ras activity in Nf1−/− murine myeloid hematopoietic cells in vitro through the c-kit receptor tyrosine kinase (dominant white spotting, W). Since the W and Nf1 locus appear to function along a common developmental pathway, we generated mice with mutations at both loci to examine potential interactions in vivo. Here, we show that haploinsufficiency at Nf1 perturbs cell fates in mast cells in vivo, and partially rescues coat color and mast cell defects in W41 mice. Haploinsufficiency at Nf1 also increased mast cell proliferation, survival, and colony formation in response to Steel factor, the ligand for c-kit. Furthermore, haploinsufficiency was associated with enhanced Ras–mitogen-activated protein kinase activity, a major downstream effector of Ras, via wild-type and mutant (W41) c-kit receptors. These observations identify a novel interaction between c-kit and neurofibromin in vivo, and offer experimental evidence that haploinsufficiency of Nf1 alters both cellular and biochemical phenotypes in two cell lineages that are affected in individuals with NF1. Collectively, these data support the emerging concept that heterozygous inactivation of tumor suppressor genes may have profound biological effects in multiple cell types

U.S. adult perceptions of the harmfulness of tobacco products: descriptive T findings from the 2013–14 baseline wave 1 of the path study

Introduction: This study is the first nationally representative survey of U.S. adults (18+) to examine perceptions of the relative harms of eight non-cigarette tobacco products. Methods: Data are from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study Adult Questionnaire, a nationally representative study of 32,320 adults in the United States conducted from September 2013 to December 2014. Results: 40.7% of adults believed that electronic cigarettes were less harmful than cigarettes, and 17.8% of adults believed that hookah was less harmful than cigarettes. Those less knowledgeable about the health risks of smoking were more likely to believe that the non-cigarette products were less harmful than cigarettes. Current non-cigarette tobacco product users were more likely to perceive that product to be less harmful than cigarettes (except filtered cigars). There was a significant positive correlation between beliefs that cigarettes were harmful and the likelihood of using hookah; perceptions of the harmfulness of cigarettes was not associated with the likelihood of using any other product. Conclusions: Perceptions of harmfulness varied widely across non-cigarette tobacco products. E-cigarettes and hookah in particular are seen as less harmful compared to cigarettes

Public-Access Defibrillation and Survival After Out-of-Hospital Cardiac Arrest

Background The rate of survival after out-of-hospital cardiac arrest is low. It is not known whether this rate will increase if laypersons are trained to attempt defibrillation with the use of automated external defibrillators (AEDs). Methods We conducted a prospective, community-based, multicenter clinical trial in which we randomly assigned community units (e.g., shopping malls and apartment complexes) to a structured and monitored emergency-response system involving lay volunteers trained in cardiopulmonary resuscitation (CPR) alone or in CPR and the use of AEDs. The primary outcome was survival to hospital discharge. Results More than 19,000 volunteer responders from 993 community units in 24 North American regions participated. The two study groups had similar unit and volunteer characteristics. Patients with treated out-of-hospital cardiac arrest in the two groups were similar in age (mean, 69.8 years), proportion of men (67 percent), rate of cardiac arrest in a public location (70 percent), and rate of witnessed cardiac arrest (72 percent). No inappropriate shocks were delivered. There were more survivors to hospital discharge in the units assigned to have volunteers trained in CPR plus the use of AEDs (30 survivors among 128 arrests) than there were in the units assigned to have volunteers trained only in CPR (15 among 107; P=0.03; relative risk, 2.0; 95 percent confidence interval, 1.07 to 3.77); there were only 2 survivors in residential complexes. Functional status at hospital discharge did not differ between the two groups. Conclusions Training and equipping volunteers to attempt early defibrillation within a structured response system can increase the number of survivors to hospital discharge after out-of-hospital cardiac arrest in public locations. Trained laypersons can use AEDs safely and effectively

A systematic review and meta-analysis of the effect of dispatcher-assisted CPR on outcomes from sudden cardiac arrest in adults and children

Background: Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) has been reported in individual studies to significantly increase the rate of bystander CPR and survival from cardiac arrest. Methods: We undertook a systematic review and meta-analysis to evaluate the impact of DA-CPR programs on key clinical outcomes following out-of-hospital cardiac arrest. We searched the PubMED, EMBASE, CINAHL, ERIC and Cochrane Central Register of Controlled Trials databases from inception until July 2018. Eligible studies compared systems with and without dispatcher-assisted CPR programs. The results of included studies were classified into 3 categories for the purposes of more accurate analysis: comparison of outcomes in systems with DA-CPR programs, case-based comparison of DA-CPR to bystander CPR, and case-based comparisons of DA-CPR to no CPR before EMS arrival. The GRADE system was used to assess certainty of evidence at an outcome level. We used random-effects models to produce summary effect sizes across all outcomes. Results: Of 5531 citations screened, 33 studies were eligible for inclusion. All included studies were observational. Evidence certainty across all outcomes was assessed as low or very low. In system-level and patient-level comparisons, the provision of DA-CPR compared with no DA-CPR was consistently associated with improved outcome across all analyses. Comparison of DA-CPR to bystander CPR produced conflicting results. Findings were consistent across sensitivity analyses and the pediatric sub-group. Conclusion: These results support the recommendation that dispatchers provide CPR instructions to callers for adults and children with suspected OHCA. Review registration: PROSPERO- CRD42018091427
