Poor weight recovery between stage 1 palliation and hospital discharge for infants with single ventricle physiology: an analysis of the NPC-QIC Phase II dataset.
The purpose of this study was to investigate change in weight-for-age z-scores (WAZ) and risk factors for impaired weight gain between stage 1 palliation (S1P) for single ventricle physiology and discharge. Data from the National Pediatric Cardiology Quality Improvement Collaborative Phase II database was analysed. Findings showed that nearly all infants lost weight after S1P, with little recovery by hospital discharge. At discharge, three-quarters of the infants were at-risk for impaired weight gain or had failure to thrive. Most risk factors associated with change in WAZ were unmodifiable or surrogates of disease severity.

Machine learning prediction of mortality and hospitalization in heart failure with preserved ejection fraction.
This study developed models to predict the risk of death and hospitalization in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Data was used from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) clinical trial. Five methods: logistic regression with a forward selection of variables; logistic regression with a lasso regularization for variable selection; random forest (RF); gradient descent boosting; and support vector machine, were used to train models for assessing risks of mortality and HF hospitalization through 3 years of follow-up and were validated using 5-fold cross-validation. RF was found to be the best performing model for predicting mortality and HF hospitalization. Blood urea nitrogen levels, body mass index, and Kansas City Cardiomyopathy Questionnaire (KCCQ) subscale scores were strongly associated with mortality, while hemoglobin level, blood urea nitrogen, time since previous HF hospitalization, and KCCQ scores were the most significant predictors of HF hospitalization.

Development of a risk tool to support discussions of care for older adults admitted to the ICU with pneumonia.
The purpose of this study was to develop a 30-day mortality prediction tool for older patients in intensive care unit (ICU) with pneumonia that will initiate palliative care earlier in hospital course. The authors suggest that their risk tool can help care teams make more informed decisions among care options by identifying a patient group for whom a careful review of goals of care is indicated both during and after hospitalization.

Characterizing functional health status of surgical patients in clinical notes.
The researchers of this study hypothesize that important functional status data is contained in clinical notes. They found that several categories of phrases related to functional status including diagnoses, activity and care assessments, physical exam, functional scores, assistive equipment, symptoms, and surgical history were important factors. They conducted a chart review and compared functional health status level terms from the chart review to National Surgical Quality Improvement Program determinations.

Hearing loss among older adults with heart failure in the United States: data from the National Health and Nutrition Examination Survey.
The researchers examined the prevalence and correlates of hearing loss among older adults with and without heart failure (HF) in the United States. Overall, 75 percent of adults 70 years or older with HF have hearing loss. Although hearing loss was more common among adults with HF compared with those without it, HF was not independently associated with hearing loss after accounting for demographic and clinical characteristics.

The modified frailty index to predict morbidity and mortality for retroperitoneal sarcoma resections.
The researchers performed a retrospective analysis of patients with a diagnosis of primary malignant retroperitoneal neoplasm who underwent surgical resection. The modified frailty index (mFI) was calculated according to standard published methods. Their data demonstrate that the majority of patients undergoing retroperitoneal sarcoma resections have few, if any, comorbidities. The mFI was a limited predictor of overall and serious complications and was not a significant predictor of mortality.

Trends in cardiovascular health of US adults by income, 2005-2014.
This research letter discusses the trends in cardiovascular health of US adults by income from 2005-2014. The investigators assessed national trends in cardiovascular risk factors by income level among adults aged 25 years and older using data from the National Health and Nutrition Examination Surveys, a nationally representative, multistage probability sample of the US population, across 5 periods: 2005 to 2006, 2007 to 2008, 2009 to 2010, 2011 to 2012, and 2013 to 2014.

Does one size fit all? The role of body mass index and waist circumference in systemic inflammation in midlife by race and gender.
This study investigated the associations of body mass index (BMI) and waist circumference (WC) with markers of systemic inflammation in midlife by race and gender. Compared to White men, Black women have higher BMI and higher levels of all four inflammation markers; White women have lower BMI, lower WC, and lower E-selectin and fibrinogen but higher C-reactive protein, and Black men have higher fibrinogen.

Young women with acute myocardial infarction: current perspectives.
The purpose of this cardiovascular perspective piece is to review recent studies of acute myocardial infarction (AMI) in young women. More specifically, it emphasizes differences in the epidemiology, diagnosis, and management of AMI in young women (when compared with men) across the continuum of care, including their pre-AMI, in-hospital, and post-AMI periods, and highlights gaps in knowledge and outcomes that can inform the next generation of research.

Combinations of chronic conditions, functional limitations, and geriatric syndromes that predict health outcomes.
The researchers aimed to identify combinations of chronic conditions, functional limitations, and geriatric syndromes that predict poor health outcomes. They found that functional limitations and/or geriatric syndromes were the most prominent conditions in predicting health outcomes. They concluded that accounting for chronic conditions alone may be less informative than also accounting for the co-occurrence of functional limitations and geriatric syndromes, as the latter conditions appear to drive health outcomes in older individuals.
