AIMS: To further characterize biphasic squamoid renal cell carcinoma (RCC), a recently proposed variant of papillary RCC. METHODS AND RESULTS: We identified 28 tumors from multiple institutions. They typically demonstrated two cell populations - larger cells with eosinophilic cytoplasm and higher-grade nuclei, surrounded by smaller, amphophilic cells with scanty cytoplasm. The dual morphology was variable (median 72.5% of tumor, range 5-100%); emperipolesis was found in all cases...

PURPOSE: To study the effects of immunosuppression on treatment toxicity, long-term cancer recurrence risk, and survival among human immunodeficiency virus (HIV)-positive anal cancer patients. METHODS AND MATERIALS: From a nationwide retrospective cohort of veterans with anal cancer we identified 142 HIV-positive patients with stage I-III disease, diagnosed between 2000 and 2015 and treated with definitive-intent chemotherapy and radiation. We used regression models to study the impact of pretreatment CD4 counts and longitudinal posttreatment CD4 counts on outcomes including acute toxicity, long-term ostomy rates, cancer recurrence, cancer-specific survival, and overall survival...

Suspected malaria cases in Africa increasingly receive a rapid diagnostic test (RDT) before antimalarials are prescribed. While this ensures efficient use of resources to clear parasites, the underlying cause of the individual's fever remains unknown due to potential coinfection with a non-malarial febrile illness. Widespread use of RDTs does not necessarily prevent over-estimation of clinical malaria cases or sub-optimal case management of febrile patients. We present a new approach that allows inference of the spatiotemporal prevalence of both Plasmodium falciparum malaria-attributable and non-malarial fever in sub-Saharan African children from 2006 to 2014...

Background: Pulmonologists provide quality care, however, their number is not adequate to take care of all the chronic obstructive pulmonary disease (COPD) needs of the population and their services come with a cost. Their optimal role should be defined, ideally based on evidence, to ensure that their abilities are applied most efficiently where needed. Objective: To determine if concomitant pulmonologist and primary care physician care after COPD hospital or emergency department discharge was associated with better health outcomes than primary care services alone...

Overconsumption of high-fat diet (HFD) and sugar-sweetened beverages are risk factors for developing obesity, insulin resistance, and fatty liver disease. Here we have dissected mechanisms underlying this association using mice fed either chow or HFD with or without fructose- or glucose-supplemented water. In chow-fed mice, there was no major physiological difference between fructose and glucose supplementation. On the other hand, mice on HFD supplemented with fructose developed more pronounced obesity, glucose intolerance, and hepatomegaly as compared to glucose-supplemented HFD mice, despite similar caloric intake...

INTRODUCTION: Pathophysiology of pneumonia involves leakage of plasma proteins into the airways and accumulation of cytokines within the lung. Several in vitro and in vivo studies have demonstrated that this proteinaceous material and lung inflammation inhibit surfactant function. AIM: To evaluate whether exogenous surfactant therapy improves oxygenation and gas exchange in late preterm and term neonates with early onset pneumonia and respiratory failure. MATERIALS AND METHODS: This prospective interventional cohort study was conducted at a tertiary care neonatal unit...

Importance: Mailed fecal immunochemical test (FIT) outreach is more effective than colonoscopy outreach for increasing 1-time colorectal cancer (CRC) screening, but long-term effectiveness may need repeat testing and timely follow-up for abnormal results. Objective: Compare the effectiveness of FIT outreach and colonoscopy outreach to increase completion of the CRC screening process (screening initiation and follow-up) within 3 years. Design, Setting, and Participants: Pragmatic randomized clinical trial from March 2013 to July 2016 among 5999 participants aged 50 to 64 years who were receiving primary care in Parkland Health and Hospital System and were not up to date with CRC screenings...

INTRODUCTION: Little is known about the nature and effects of mentoring interventions on evidence-based clinician behaviors. We sought to design and evaluate a novel mentorship-based intervention to improve the usage of spirometry in primary care. METHODS: This was a prospective one-year study of a pragmatic intervention across Canadian primary care sites. We established mentor-mentee pods, each including physician and nurse/allied health mentors and mentees, and enabled communication through a secure online portal; email; telephone; teleconference; videoconference; fax; and/or in person...

BACKGROUND: HIV-infected patients have an increased risk of cardiovascular disease (CVD). Impaired endothelial function is an early risk factor for CVD in the general population. It is presumed that HIV infection is associated with impaired endothelial function, but results have been inconsistent. OBJECTIVES: Our objectives were to determine the relationships between HIV infection, virologic suppression with antiretroviral therapy (ART), in vivo measures of conduit artery and microvascular endothelial function, and circulating biomarkers of pathways associated with CVD...

BACKGROUND: We previously demonstrated that in addition to generating an antigen-specific immune response, Listeria monocytogenes (Lm)-based immunotherapy significantly reduces the ratio of regulatory T cells (Tregs)/CD4(+) and myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment. Since Lm-based immunotherapy is able to inhibit the immune suppressive environment, we hypothesized that combining this treatment with agonist antibody to a co-stimulatory receptor that would further boost the effector arm of immunity will result in significant improvement of anti-tumor efficacy of treatment...

BACKGROUND: Obstructive sleep apnea (OSA) is an independent risk factor for many cardiovascular conditions such as coronary artery disease, myocardial infarction, systemic hypertension, pulmonary hypertension, and stroke. However, the association of OSA with outcomes in patients hospitalized for ST-elevation myocardial infarction remains controversial. METHODS AND RESULTS: We used the nation-wide inpatient sample between 2003 and 2011 to identify patients with a primary discharge diagnosis of ST-elevation myocardial infarction and then used the International Classification of Diseases, Clinical Modification code 327...

Hemoptysis is considered as a medical emergency which requires urgent stabilization with identification and correction of underlying etiology. Diagnosis of the cause of hemoptysis is not always readily identified after bronchoscopy and conventional computed tomography (CT) chest. Arteriovenous malformation (AVM) is a rare but important cause of massive hemoptysis which can be easily picked up by the use of double turn contrast CT chest. We here report a rare congenital AVM anomaly called Klippel-Trenaunay-Parks-Weber syndrome as a cause of massive hemoptysis and utility of double turn CT in diagnosing AVM as a cause of hemoptysis...

Regular use of colorectal cancer screening can reduce incidence and mortality, but participation rates remain low among low-income, Spanish-speaking Latino adults. We conducted two distinct pilot studies testing the implementation of evidence-based interventions to promote fecal immunochemical test (FIT) screening among Latinos aged 50-75 years who were not up-to-date with CRC screening (n = 200) at a large Federally Qualified Health Center (FQHC) in San Diego, CA. One pilot focused on an opportunistic clinic visit "in-reach" intervention including a 30-min session with a patient navigator, review of an educational "flip-chart," and a take-home FIT kit with instructions...

Spermatogenesis, involving multiple transit amplification divisions and meiosis, occurs within an enclosure formed by two somatic cells. As the cohort of germline cells divide and grow, the surface areas of the somatic cells expand maintaining a tight encapsulation throughout the developmental period. Correlation between the somatic cell growth and germline development is unclear. Here, we report standardization of a quantitative assay developed for estimating the somatic roles of target molecules on germline division and differentiation in Drosophila testis...

Follicular Th (Tfh) cells are a distinct subset of Th cells that help B cells produce class-switched antibodies. Studies have demonstrated that Tfh cells are highly prone to HIV infection and replication. However, the molecular mechanisms underlying this phenomenon are largely unclear. Here, we show that murine and human Tfh cells have diminished constitutive expression of IFN-stimulated genes (ISGs) inclusive of antiviral resistance factor MX dynamin-like GTPase 2 (MX2) and IFN-induced transmembrane 3 (IFITM3) compared with non-Tfh cells...
