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...

A fast-growing stalagmite from the central California coast provides a high-resolution record of climatic changes synchronous with global perturbations resulting from the catastrophic drainage of proglacial Lake Agassiz at ca. 8.2 ka. High frequency, large amplitude variations in carbon isotopes during the 8.2 ka event, coupled with pulsed increases in phosphorus concentrations, indicate more frequent or intense winter storms on the California coast. Decreased magnesium-calcium ratios point toward a sustained increase in effective moisture during the event, however the magnitude of change in Mg/Ca suggests this event was not as pronounced on the western North American coast as anomalies seen in the high northern latitudes and monsoon-influenced areas...

BACKGROUND: Physical activity is beneficial in people with dementia. As physical activity increases risk exposure for falls, safety concerns arise. Prior exercise trials in people with dementia have not measured physical activity. Falls in relation to exposure time rather than person-years as outcome measure has been promoted but not investigated in people with dementia. METHODS: Patients with mild to moderate dementia (n=110) were randomized to an intensive, progressive strength and functional training intervention or to a low-intensity group training for 12 weeks each...

OBJECTIVE: In venous leg ulcer (VLU), the impaired healing has been shown to be associated with excessive levels of protease activities such as matrix metalloproteinases (MMPs) and elastases found in exudates. The present study focused on exudates absorption and proteases trapping capacity of a new generation of polyacrylate superabsorbent, Tegaderm superabsorber (TS), compared with a traditional dressing such as Zetuvit. METHOD: We studied the proteases implicated in VLU (MMP-1, MMP-2, MMP-9 and PMN elastase)...

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...

OBJECTIVE: Circadian Clock gene mutant mice show dampened 24-h feeding rhythms and an increased sensitivity to high-fat diet (HFD) feeding. Restricting HFD access to the dark phase counteracts its obesogenic effect in wild-type mice. The extent to which altered feeding rhythms are causative for the obesogenic phenotype of Clock mutant mice, however, remains unknown. METHODS: Metabolic parameters of wild-type (WT) and Clock(Δ19) mutant mice (MT) were investigated under ad libitum and nighttime restricted HFD feeding...

Online studies of single airborne particles represent a demanding challenge in aerosol chemistry. New technologies that help to unravel the role of ambient aerosols in earth climate and to assess local and specific health risks from air pollution are highly desired. Of particular relevance are polycyclic aromatic hydrocarbons (PAHs) from combustion processes that are associated with both acute and long-term health effects. Usually, online single particle analyses apply laser desorption/ionization (LDI) in a bipolar mass spectrometer, revealing elemental constituents and limited molecular information by detection of both positive and negative ions...

ONC201 is an oral, small molecule selective antagonist of the G protein-coupled receptor DRD2 that causes p53-independent apoptosis in tumor cells via integrated stress response activation and Akt/ERK inactivation. We performed a Phase II study that enrolled 17 patients with recurrent, bevacizumab-naïve, IDH1/2 WT glioblastoma who received 625mg ONC201 every three weeks. Median OS was 41.6 weeks with OS6 of 71% and OS9 of 53%. Seven of 17 patients are alive. PFS6 was 11.8% with two patients remaining on study who continue to receive ONC201 for >12 months...

Peer support is increasingly provided as a component of mental health care, where people in recovery from mental health problems use their lived experiences to provide support to those experiencing similar difficulties. In the present study, we explored the evolution of peer support workers' (PSW) occupational identities. A qualitative study was undertaken alongside a pilot randomized, controlled trial of peer support for service users discharged from a mental hospital in London, UK. Two focus groups were conducted with eight PSW...

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...

BACKGROUND: Diagnostic agreement among pathologists is 84% for ductal carcinoma in situ (DCIS). Studies of interpretive variation according to grade are limited. METHODS: A national sample of 115 pathologists interpreted 240 breast pathology test set cases in the Breast Pathology Study and their interpretations were compared to expert consensus interpretations. We assessed agreement of pathologists' interpretations with a consensus reference diagnosis of DCIS dichotomised into low- and high-grade lesions...

OBJECTIVE: A substantial percentage of children with congenital heart disease (CHD) fail to transfer to adult care, resulting in increased risk of morbidity and mortality. Transition planning discussions with a provider may increase rates of transfer, yet little is known about frequency and content of these discussions. We assessed prevalence and predictors of transition-related discussions between providers and parents of children with special healthcare needs (CSHCN) and heart problems, including CHD...

PI3Kδ is a lipid kinase that is believed to be important in the migration and activation of cells of the immune system. Inhibition is hypothesized to provide a powerful yet selective immunomodulatory effect that may be beneficial for the treatment of conditions such as asthma or rheumatoid arthritis. In this work, we describe the identification of inhibitors based on a thiazolopyridone core structure and their subsequent optimization for inhalation. The initially identified compound (13) had good potency and isoform selectivity but was not suitable for inhalation...

Anti-cancer small molecule ONC201 upregulates the integrated stress response (ISR) and acts as a dual inactivator of Akt/ERK, leading to TRAIL gene activation. ONC201 is under investigation in multiple clinical trials to treat patients with cancer. Given the unique imipridone core chemical structure of ONC201, we synthesized a series of analogues to identify additional compounds with distinct therapeutic properties. Several imipridones with a broad range of in vitro potencies were identified in an exploration of chemical derivatives...

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...
