Nitric oxide (NO) is a therapeutic implicated for the treatment of diseases affecting lymphatic tissues, which range from infectious and cardiovascular diseases to cancer. Existing technologies available for NO therapy, however, provide poor bioactivity within lymphatic tissues. In this work, we address this technology gap with a NO encapsulation and delivery strategy leveraging the formation of S-nitrosothiols on lymphatic-targeting Pluronic-stabilized, poly(propylene sulfide)-core nanoparticles (SNO-NP). We evaluated in vivo the lymphatic versus systemic delivery of NO resulting from intradermal administration of SNO-NP benchmarked against a commonly used, commercially available small molecule S-nitrosothiol NO donor, examined signs of toxicity systemically as well as localized to the site of injection, and investigated SNO effects on lymphatic transport and NP uptake by LN-resident cells...

AIMS: We evaluated the simultaneous effects of all clinically recognized categories of albuminuria and estimated glomerular filtration rate (eGFR) on cardiovascular disease (CVD) and mortality. METHODS: We conducted a longitudinal observational study of 16,678 type 2 diabetes (T2D) patients. From the first serum creatinine value from 2006 to 2012 and a urine-albumin creatinine ratio (UACR) recorded within 6months, we applied baseline Kidney Disease: Improving Global Outcomes (KDIGO) categories of eGFR and albuminuria...

Whole thoracic irradiation (WTI) is known to cause deterioration in cardiac function. Whether irradiation predisposes the heart to further ischemia and reperfusion (IR) injury is not well known. The aim of this study is to examine the susceptibility of rat hearts to IR injury following a single fraction of 15 Gy WTI and to investigate the role of mitochondrial metabolism in the differential susceptibility to IR injury. After day 35 of irradiation, ex vivo hearts from irradiated and nonirradiated rats (controls) were exposed to 25-min global ischemia followed by 60-min IR, or hearts were perfused without IR for the same protocol duration [time controls (TC)]...

BACKGROUND: Excessive daytime sleepiness (EDS), a common symptom among patients with sleep-disordered breathing, is closely associated with the development of cardiovascular diseases, but its long-term prognostic value is not completely understood. The aim of this study was to investigate whether EDS would be an independent prognostic factor after myocardial infarction. METHODS AND RESULTS: We prospectively recruited 112 post-myocardial infarction patients. The Epworth Sleepiness Scale was completed before polysomnography, and EDS was defined as a score ≥11...

REVIEW
Dino Trtovac, Joon Lee
BACKGROUND: Malnutrition is a condition most commonly arising from the inadequate consumption of nutrients necessary to maintain physiological health and is associated with the development of cardiovascular disease, osteoporosis, and sarcopenia. Malnutrition occurring in the hospital setting is caused by insufficient monitoring, identification, and assessment efforts. Furthermore, the ability of health care workers to identify and recognize malnourished patients is suboptimal. Therefore, interventions focusing on the identification and treatment of malnutrition are valuable, as they reduce the risks and rates of malnutrition within hospitals...

BACKGROUND AND AIMS: About 6-7% of high density lipoprotein (HDL) has a protein called apolipoprotein (apo) C-III that regulates lipoprotein metabolism and can provoke an inflammatory response. HDL without apoC-III is inversely associated with coronary heart disease (CHD), whereas HDL with apoC-III is directly associated with CHD. We investigated how the presence of apoC-III affects the association between HDL and early stages of atherosclerosis measured as carotid intima-media thickness (cIMT)...

BACKGROUND AND AIMS: Elevated circulating levels of fibroblast growth factor 21 (FGF21) are associated with multiple cardiovascular disease (CVD) risk factors and incident events. Previous small cross-sectional studies, mainly in Chinese populations, have suggested FGF21 may play a role in the development of atrial fibrillation (AF). We therefore investigated the relationship of FGF21 levels with incident AF in participants free of clinically apparent CVD at baseline in a large, multi-ethnic cohort...

BACKGROUND: Video vignettes are used to test the effects of physicians' communication on patient outcomes. Methodological choices in video-vignette development may have far-stretching consequences for participants' engagement with the video, and thus the ecological validity of this design. To supplement the scant evidence in this field, this study tested how variations in video-vignette introduction format and camera focus influence participants' engagement with a video vignette showing a bad news consultation...
