Tobacco and marijuana use among U.S. young adults is a top public health concern, and racial/ethnic minorities may be at particular risk. Past research examining cultural variables has focused on the individual in relation to the mainstream U.S. culture; however, an individual can also experience within-group stress, or intragroup marginalization. We used the 2014 San Francisco Bay Area Young Adult Health Survey to validate an abbreviated measure of intragroup marginalization and identify associations between intragroup marginalization and tobacco and marijuana use among ethnic minority young adults (N = 1,058)...

An evaluation of the virus population in rice plants using next-generation sequencing technologies resulted in the discovery of a new RNA virus, tentatively named rice virus A (RVA). The complete RVA genome sequence was determined and analyzed, revealing a genome organization resembling that of viruses classified in the genera Aureusvirus, Tombusvirus and Zeavirus within the family Tombusviridae. With 4,832 nucleotides, the RVA genome may be the largest monopartite genome sequenced to date in the family Tombusviridae...

Lauren E Rotman, Mark R Harrigan
Dr. Norman Chater, a University of California, San Francisco-trained microvascular neurosurgeon, dedicated his career to the development of surgical bypass techniques. His work contributed to advancements in microvascular anatomy and the development of cerebral revascularization techniques. He identified Chater's point, an extracranial landmark that marks the posterior extent of the Sylvian fissure, which upon craniectomy reliably exposes vessels of the angular gyrus, vasculature found to be most appropriate for bypass procedures due to their accessibility and vascular diameter...

Early initiation of antiretroviral therapy (ART) reduces the risk of drug-sensitive HIV transmission but may increase the transmission of drug-resistant HIV. We used a mathematical model to estimate the long-term population-level benefits of ART and determine the scenarios under which earlier ART (treatment at 1 year post-infection, on average) could decrease simultaneously both total and drug-resistant HIV incidence (new infections). We constructed an infection-age-structured mathematical model that tracked the transmission rates over the course of infection and modelled the patients' life expectancy as a function of ART initiation timing...

BACKGROUND: Breast-conservation surgery with radiotherapy is a treatment highly recommended by the guidelines from the National Comprehensive Cancer Network. However, several variables influence the final receipt of radiotherapy and it might not be administered to breast cancer patients. Our objective is to propose a systematic framework to identify the clinical and non-clinical variables that influence the receipt of unexpected radiotherapy treatment by means of Bayesian networks and a proposed heuristic approach...

This article reports findings from a qualitative study of food practices among families of differing socioeconomic circumstances. Using in-depth interviews from sixty-two families in the San Francisco Bay Area in 2015-2016, we find socioeconomic differences in how mothers and adolescents talk about food. Across SES, mothers and adolescents engage in discussions about healthy eating. However, these conversations are more commonplace and embedded within high-SES family life than among low-SES families. Beyond conversations about 1) healthy eating, the topics of 2) food quality and 3) price are discussed to varying degrees across SES...

Galectin-8 (Gal-8) is a member of a glycan-binding protein family that regulates the immune system, among other functions, and is a target of antibodies in autoimmune disorders. However, its role in multiple sclerosis (MS), an autoimmune inflammatory disease of the central nervous system (CNS), remains unknown. We study the consequences of Gal-8 silencing on lymphocyte subpopulations and the development of experimental autoimmune encephalitis (EAE), to then assess the presence and clinical meaning of anti-Gal-8 antibodies in MS patients...

We examined whether beliefs about antiretroviral (ART) efficacy and reinfection prospectively predicted subsequent condomless anal intercourse (CAI). Men who have sex with men in San Francisco (N = 773) were recruited for a longitudinal study using time-location sampling. HIV-negative men were more likely to have sero-discordant receptive CAI and HIV-positive men were more likely to have sero-discordant insertive CAI if they previously reported these behaviors at baseline and reported less concern about HIV transmission due to ART...

BACKGROUND: Patients with hypersensitivity pneumonitis are at risk of developing pulmonary fibrosis, which is associated with reduced survival. In families with multiple affected members, individuals might be diagnosed as having idiopathic pulmonary fibrosis (IPF) or chronic (fibrotic) hypersensitivity pneumonitis, which suggests these disorders share risk factors. We aimed to test whether the genomic risk factors associated with the development and progression of IPF are also associated with the development of fibrosis and reduced survival in people with chronic hypersensitivity pneumonitis...
