In efforts to increase rigor and reproducibility, the USA National Primate Research Centers (NPRCs) have focused on qualification of reagents, cross-laboratory validations, and proficiency testing for methods to detect infectious agents and accompanying immune responses in nonhuman primates. The pathogen detection working group, comprised of laboratory scientists, colony managers, and leaders from the NPRCs, has championed the effort to produce testing that is reliable and consistent across laboratories. Through multi-year efforts with shared proficiency samples, testing percent agreement has increased from as low as 67.

Background: The emergence of SARS-CoV-2 and the ensuing COVID-19 pandemic prompted the need for a surveillance program to determine the viral status of the California National Primate Research Center non-human primate breeding colony, both for reasons of maintaining colony health and minimizing the risk of interference in COVID-19 and other research studies.

Methods: We collected biological samples from 10% of the rhesus macaque population for systematic testing to detect SARS-CoV-2 virus by RT-PCR and host antibody response by ELISA. Testing required the development and validation of new assays and an algorithm using in laboratory-developed and commercially available reagents and protocols.

Subsets of esophagogastric (EG) cancers harbor genetic abnormalities, including amplification of HER2, MET, or FGFR2 or mutations in PIK3CA, EGFR, or BRAF. Ganetespib which is a novel triazolone heterocyclic inhibitor of HSP90, is a potentially biologically rational treatment strategy for advanced EG cancers with these gene amplification. This multicenter, single-arm phase 2 trial enrolled patients with histologically confirmed advanced EG cancer with progression on at least one line of systemic therapy.

To better understand Simian betaretrovirus (SRV) seropositivity in virus-negative macaques, we transfused blood from SRV-infected or suspect donors into immunosuppressed naive recipients. Our results do not support typical SRV1-5 infection as the cause, but provide evidence for several possibilities including serological artifact, new/different SRV, or an endogenous virus.

Objectives: We describe the unique selling propositions (USPs) (propositions used to convince customers to use a particular brand/product by focusing on the unique benefit) of print tobacco ads.

Methods: A qualitative content analysis was conducted of print tobacco ads (N = 171) selected from August 2012 to August 2013 for cigarettes, moist snuff, e-cigarettes, cigars, and snus to determine the content and themes of USPs for tobacco ads.

Results: Cigarette ad USP themes focused on portraying the product as attractive; moist snuff ads focused on portraying product as masculine; cigar ads focused on selling a "high end product;" and new and emerging tobacco products (e-cigarette, snus) focused on directly comparing these products to cigarettes.

The purpose of this survey study was to evaluate a model of body image influences on indoor tanning behavior. Participants were 823 young adult women recruited from a probability-based web panel in the United States. Consistent with our hypothesized model, tanning-related sociocultural experiences were indirectly associated with lifetime indoor tanning use and intentions to tan as mediated through tan surveillance and tan dissatisfaction.

Intracerebral haemorrhage (ICH) is associated with the greatest morbidity and mortality of all stroke subtypes. Established risk factors for ICH include hypertension, alcohol use, current cigarette smoking, and use of oral anticoagulants and/or antiplatelet agents. Familial aggregation of ICH has been observed, and the heritability of ICH risk has been estimated at 44%.

Drawing on the logic of the relational turbulence model, this study examined the ways in which romantic partners facilitate and interfere with individuals' weight loss goals. Participants (N = 122) described the ways in which their romantic partner had recently helped or hindered their weight loss at four times over the course of 2 months. We conducted a content analysis of responses to identify themes of partner facilitation (Research Question 1 [RQ1]) and partner interference (RQ2) in individuals' weight loss goals.

Media literacy interventions offer promising avenues for the prevention of risky health behaviors among children and adolescents, but current literature remains largely equivocal about their efficacy. The primary objective of this study was to develop and test theoretically-grounded measures of audiences' degree of engagement with the content of media literacy programs based on the recognition that engagement (and not participation per se) can better explain and predict individual variations in the effects of these programs. We tested the validity and reliability of a measure of engagement with two different samples of 10 grade high school students who participated in a pilot and actual test of a brief media literacy curriculum.

The ICH score is a validated method of assessing the risk of mortality and morbidity after intracerebral hemorrhage (ICH). We sought to compare the ability of the ICH score to predict outcome assessed with three of the most widely used scales: the Barthel Index (BI), modified Rankin Scale (mRS), and Glasgow Outcome Score (GOS). All patients with ICH treated at our institution between February 2009 and March 2011 were followed-up at three months using the mRS, GOS, and BI.
