Endogenous circadian clocks regulate 24 h rhythms of physiology and behavior. Circadian rhythm disruption (CRD) is suggested as a risk factor for inflammatory bowel disease. However, the underlying molecular mechanisms remain unknown. Intestinal biopsies from Per1/2 mutant and wild-type (WT) mice were investigated by electron microscopy, immunohistochemistry, and bromodeoxyuridine pulse-chase experiments. TNF-α was injected intraperitoneally, with or without necrostatin-1, into Per1/2 mice or rhythmic and externally desynchronized WT mice to study intestinal epithelial cell death...

The attrition of telomeres is believed to be a key event not only in mammalian aging, but also in disturbed nutrient sensing, which could lead to numerous metabolic dysfunctions. The current debate focuses mainly on the question whether telomere shortening, e.g., as a heritable trait, may act as a cause or rather represents a consequence of such chronic diseases. This review discusses the damaging events that ultimately may lead or contribute to telomere shortening and can be associated with metabolic diseases...

Rationale Patients with idiopathic pulmonary fibrosis and emphysema may have artificially preserved lung volumes. Objectives This post-hoc analysis investigated the relationship between baseline emphysema and fibrosis extents, and pulmonary function changes over 48 weeks. Methods Data were pooled from two Phase III, randomized, double-blind, placebo-controlled trials of interferon γ-1b in idiopathic pulmonary fibrosis (GIPF-001 [NCT00047645]; GIPF-007 [NCT00075998]). Patients with Week 48 data, baseline high-resolution computed tomography images and forced expiratory volume in 1 second/forced vital capacity ratios <0...

OBJECTIVES: Haemodynamically stable patients admitted for coronary artery bypass grafting in acute myocardial infarction often undergo delayed surgery in order to avoid the risks of emergency surgery. However, initially stable patients undergoing delayed surgery may develop low cardiac output syndrome (LCOS) during the waiting period, which might be a major drawback of this strategy. We aim to define risk factors and clinical consequences of LCOS during the waiting period. METHODS: A total of 530 consecutive patients with acute myocardial infarction (33% non-ST-segment elevation myocardial infarction and 67% ST-segment-elevation myocardial infarction) underwent isolated coronary artery bypass grafting between 2008 and 2013...

Using data from the Study of Osteoporotic Fractures (SOF), several clinical characteristics predictive of near-term (1-year) risk of hip and non-vertebral fracture among elderly osteoporotic women were identified, and a subset of those for hip fracture was incorporated into a risk assessment tool. Additional research is needed to validate study findings. INTRODUCTION: While several risk factors are known to contribute to long-term fracture risk in women with osteoporosis, factors predicting fracture risk over a shorter time horizon, such as over a 1-year period, are less well-established...

Replicating a research study that described the work of nurse scientists in children's hospitals, the purpose of the study was to describe the role, activities, and outcomes of nurse scientists employed in a national health care organization. The characteristics of nurses filling the nurse scientist role in clinical settings and outcomes associated with the role have not been extensively described. The setting of this study is ideal since the organization includes facilities of various sizes located in rural, urban, and suburban areas in 18 states...

PURPOSE: Data from large randomized controlled trials confirming sleep quality improvements with aerobic physical activity have heretofore been lacking for post-primary treatment breast cancer survivors. Our primary purpose for this report was to determine the effects of a physical activity behavior change intervention, previously reported to significantly increase physical activity behavior, on sleep quality in post-primary treatment breast cancer survivors. METHODS: Post-primary treatment breast cancer survivors (n=222) were randomized to a 3-month physical activity behavior change intervention (BEAT Cancer) or usual care...

The Department of Health and Human Services recommends drug resistance testing at linkage to HIV care. Because receipt and timing of testing are not well characterized, we examined testing patterns among persons with diagnosed HIV who are linked to care. Using surveillance data in six jurisdictions for persons aged ≥13 years with HIV infection diagnosed in 2013, we assessed the proportion receiving testing, and among these, the proportion receiving testing at linkage. Multivariable log-binomial regression modeling estimated associations between selected characteristics and receipt of testing (1) overall, and (2) at linkage among those tested...

Test-and-treat programs are central to the global control of HIV, but transmitted drug resistance threatens the effectiveness of these programs. HIV mutations conferring resistance to antiretroviral drugs reduce replicative fitness in vitro, but their effect on propagation in vivo is less understood. Here, we estimate transmission fitness of these mutations in antiretroviral-naïve populations in the U.S. National HIV Surveillance System by comparing their frequency of clustering in a genetic transmission network relative with wild-type viruses...

Men who have sex with men and women (MSMW) compose a subset of men who have sex with men (MSM) and represent an estimated 35% of MSM. Research on the HIV risk behaviors of MSMW has largely focused on their behaviors in comparison to men who have sex with men only (MSMO). Results suggest that compared to MSMO, MSMW are less likely to have ever had an HIV test, are at greater risk of being unaware of their HIV infection and are less likely to have encountered HIV prevention activities or materials. Additional research is needed to provide a more comprehensive understanding of the unique sexual behaviors and lived experience of MSMW as a group in order to better inform HIV prevention efforts...

PURPOSE: The aim of the analysis was to explore HIV-1 subtype diversity in the United States and understand differences in prevalence of non-B subtypes and circulating recombinant forms (CRFs) between demographic/risk groups and over time. METHODS: We included HIV-1 polymerase sequences reported to the National HIV Surveillance System for HIV infections diagnosed during 2006-2013 in seven states. We assigned subtype or CRF using the automated subtyping tool COMET, assessed subtype/CRF prevalence by demographic characteristics and country of birth, and determined changes in subtype/CRF by HIV diagnosis year...

OBJECTIVE: Bicuspid aortic valve (BAV) disease is associated with potential lifetime complications, but auscultation of a BAV click is commonly missed or mistaken for a benign split first heart sound. Our objective was to determine whether pediatric cardiologists could reliably distinguish between BAV clicks and benign split first heart sounds. DESIGN: Quality evaluation project using de-identified recordings from an outpatient pediatric cardiology clinic. OUTCOME MEASURES: Twenty-one cardiologists listened to five de-identified recordings of pediatric heart sounds (three with BAV clicks, two with mitral components of benign split first heart sounds) and indicated whether they believed each recording was a BAV or split first heart sound...

Superoxide dismutases (SOD) are a group of enzymes that catalyze the dismutation of superoxide (O2(-)) radicals into molecular oxygen (O2) and H2O2 as a first line of defense against oxidative stress. Here, we show that glycine-functionalized copper(ii) hydroxide nanoparticles (Gly-Cu(OH)2 NPs) are functional SOD mimics, whereas bulk Cu(OH)2 is insoluble in water and catalytically inactive. In contrast, Gly-Cu(OH)2 NPs form water-dispersible mesocrystals with a SOD-like activity that is larger than that of their natural CuZn enzyme counterpart...

PURPOSE: To examine the association of age when adult height was attained with glioma risk. METHODS: We analyzed data from a US-based case-control study of glioma risk factors. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) associated between age at attainment of adult height and glioma risk. Multivariate models were adjusted for age, race, sex, education, and state of residence. We examined associations overall, and according to glioma grade, sex, and final adult height...
