BACKGROUND: Factors affecting kidney function and proteinuria among HIV+ and HIV- persons need better characterization. METHODS: We evaluated estimated glomerular filtration rate (eGFR, mL/min per 1.73 m) changes, proteinuria prevalence (a urine protein-to-creatinine ratio [UPCr] of ≥0.2 at two consecutive visits) and associated factors among HIV+ and HIV- men. RESULTS: There were 917 HIV+ men receiving HAART, 159 HIV+ men not receiving HAART, and 1305 HIV- men seen from 10/2003 to 9/2014...

We evaluated outcomes of 100 patients with high risk AML treated with Ida-FLAG induction as first-line therapy. 72 achieved remission with one cycle; 19 did not. High risk cytogenetics and TP53 mutations were associated with failure to achieve remission. In those reaching remission, allogeneic bone marrow transplantation was associated with better relapse-free and overall survival. Those not achieving remission with induction therapy were extremely unlikely to reach remission with further therapy and had a dismal prognosis...

BACKGROUND AND AIMS: Colorectal cancer (CRC) screening can reduce CRC incidence and mortality, but measuring screening adherence over time is challenging. We examined adherence using a novel measure characterizing the proportion of time covered (PTC) by screening tests. METHODS: Eligible patients were age 50 to 60 years and followed at a large, safety-net healthcare system between January 2010 and September 2014. We estimated PTC as the number of days up-to-date with screening divided by number of days from cohort entry until study end, CRC diagnosis, or death...

OBJECTIVES: Little is known about the relationship between having a first-degree relative (FDR) with colorectal cancer (CRC) and risk for metachronous colorectal adenoma (CRA) following polypectomy. METHODS: We pooled data from seven prospective studies of 7697 patients with previously resected CRAs to quantify the relationship between having a FDR with CRC and risk for metachronous adenoma. RESULTS: Compared with having no family history of CRC, a positive family history in any FDR was significantly associated with increased odds of developing any metachronous CRA (OR = 1...

The NCCN Guidelines for Genetic/Familial High-Risk Assessment: Colorectal provide recommendations for the management of patients with high-risk syndromes associated with an increased risk of colorectal cancer (CRC). The NCCN Panel for Genetic/Familial High-Risk Assessment: Colorectal meets at least annually to assess comments from reviewers within their institutions, examine relevant data, and reevaluate and update their recommendations. These NCCN Guidelines Insights focus on genes newly associated with CRC risk on multigene panels, the associated evidence, and currently recommended management strategies...

BACKGROUND: Stereotactic body radiation therapy (SBRT) has been proposed as a potential alternative to surgery for early lung cancer, although we lack well-powered prospective randomized data comparing these treatments, and existing studies suffer from incomplete information on confounders that can bias results. Here, we evaluated the comparative effectiveness of surgery and SBRT in lung cancer treatment using a large extensively detailed database from the Veteran's Affairs system. METHODS: We identified veterans with biopsy-proven clinical stage I non-small cell lung cancer diagnosed between 2006 and 2015 from within the Veteran's Affairs Informatics and Computing Infrastructure...

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...

BACKGROUND/AIMS: This study examined correlates of the brain's neurocognitive performance among clinically and biochemically normal adult patient with hepatitis C virus (HCV). We hypothesized that anti-HCV positive individuals would demonstrate structural brain abnormalities and neurocognitive dysfunction as well as the changes in cell component and extracellular space in the white matter regions of brain in asymptomatic HCV infection by using diffusion tensor tractrography (DTT) metrics...
