Life years lost and lifetime health care expenditures associated with diabetes in the U.S., National Health Interview Survey, 1997-2000.
The authors analyzed the lifetime health care expenditures and life years lost associated with diabetes in the U.S. Their results showed that diabetes is associated with large decreases in life expectancy and large increases in lifetime health care expenditures, with the life years and expenditures depending on age-race-sex-BMI classification groups.

Perfect storm: concurrent stress and depressive symptoms increase risk of myocardial infarction or death.
A recently offered psychosocial perfect storm conceptual model hypothesizes amplified risk will occur in those with concurrent stress and depressive symptoms. The authors tested this hypothesis in a large sample of US adults with coronary heart disease. They found that those with low stress and high depressive symptoms or high stress and low depressive symptoms were not at increased risk, while participants with concurrent high stress and high depressive symptoms had increased risk for myocardial infarction or death relative to those with low stress and low depressive symptoms. They concluded that their results provide initial support for a psychosocial perfect storm conceptual model.

Association of left ventricular systolic function and vasopressor support with survival following pediatric out-of-hospital cardiac arrest.
This study characterizes the association of hospital discharge survival with left ventricular systolic function evaluated by transthoracic echocardiography and vasoactive infusion support following return of spontaneous circulation after pediatric out-of-hospital cardiac arrest. It found that in patients receiving transthoracic echocardiography within the first 24 hours, decreased left ventricular systolic function and vasopressor use were common.

Morbidity, mortality, cost, and survival estimates of gastrointestinal anastomotic leaks.
The aims of this study were to examine the incidence of anastomotic leaks, a potentially deadly postoperative occurrence following gastrointestinal surgery, to identify risk factors predictive of leaks, and to explore the impact of anastomotic leaks on hospital cost and patient survival. The study demonstrates that anastomotic leaks remain a major source of increased morbidity, mortality, and hospital resource use for gastrointestinal surgery.

The cost of an Ebola case.
The researchers developed a mathematical model to estimate the cost of an Ebola virus disease (EVD) case from the provider and societal perspectives in the three most affected countries of Guinea, Liberia, and Sierra Leone. Their model estimates the total societal cost of an EVD case with full recovery ranges from $480 to $912, while that of an EVD case not surviving ranges from $5,929 to $18,929, varying by age and country.

The value of adding laboratory data to coronary artery bypass grafting registry data to improve models for risk-adjusting provider mortality rates.
The purpose of this study was to determine whether the addition of laboratory data to the clinical database for coronary artery bypass graft (CABG) would identify laboratory variables that are significant independent predictors of short-term (in-hospital / 30-day) mortality. The researchers found that there was no significant difference in the discrimination of the registry model or the combined registry/laboratory model.

Validation study of medicare claims to identify older US adults with CKD using the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study.
The researchers compared characteristics and outcomes for individuals with chronic kidney disease (CKD) defined using laboratory measurements versus claims data from 6,982 study participants who had Medicare fee-for-service coverage. They found that CKD, whether identified using a claims-based algorithm or through estimated glomerular filtration rate or albumin-creatinine ratio measurements, is associated with increased risk for all-cause mortality and end-stage renal disease (ESRD).

Donor hepatitis C sero-status does not impact survival in liver transplantation.
The researchers sought to assess the impact of both donor and recipient HCV status on patient and graft survival. They found that the use of HCV+ grafts in HCV+ recipients is not associated with worse outcomes. They conclude that with the increase in HCV+patients awaiting an organ, more consideration should be given to HCV+ donors.

Relative contributions of complications and failure to rescue on mortality in older patients undergoing pancreatectomy.
This study evaluated the relative contribution of overall postoperative complications and failure to rescue rates on the observed increased mortality in older patients undergoing pancreatic resection at specialized centers. The study found that patients 80 years and older had no difference in complication rates but higher failure to rescue rates compared to patients younger than 80.

Development and pilot feasibility study of a health information technology tool to calculate mortality risk for patients with asymptomatic carotid stenosis: the Carotid Risk Assessment Tool (CARAT).
The researchers describe the development of the CArotid Risk Assessment Tool (CARAT) into a 2-year mortality risk calculator within the electronic medical record. They integrated the tool into the clinical workflow, trained the clinical team to use the tool, and assessed the feasibility and acceptability of the tool in one clinic setting.

Does the use of neoadjuvant therapy for pancreatic adenocarcinoma increase postoperative morbidity and mortality rates?
The researchers used data from the NSQIP Pancreatectomy Demonstration Project (11/2011 to 12/2012) to identify patients with pancreatic adenocarcinoma who did and did not receive neoadjuvant therapy. They found that despite evidence for more extensive disease, patients receiving neoadjuvant therapy did not experience more complications. Neoadjuvant radiation was associated with lower pancreatic fistula rates.

Effect of deregionalized care on mortality in very low-birth-weight infants with necrotizing enterocolitis.
The study’s aims were to describe the current trend toward deregionalization and to test the hypothesis that infants with necrotizing enterocolitis represent a particularly high-risk subgroup of the VLBW population that would benefit from early identification, increased intensity of early management, and possible targeted triage to tertiary hospitals. It found that outcomes for VLBW infants continue to be suboptimal when they are not born into high-level, high-volume centers.

Statin therapy after infrainguinal bypass surgery for critical limb ischemia is associated with improved 5-year survival.
The aim of this study was to determine the effect of long-term statin use after lower extremity bypass grafting on patient-related and graft-related outcomes. It found that statin therapy is associated with a 5-year survival benefit after lower extremity bypass in patients with critical limb ischemia. However, 1-year limb-related outcomes were not influenced by statin use in our large observational cohort of patients undergoing revascularization in New England.

Treatment of diffuse large B-cell lymphoma in the elderly: regimens without anthracyclines are common and not futile.
This study characterized treatment choices and compared the 3-year overall survival rates of 8262 Medicare beneficiaries diagnosed with diffuse large B-cell lymphoma in 2000 – 2006. It found that patients treated with anthracycline-containing regimens with rituximab have the highest survival rates when all available clinical features are accounted for.
