The consequences of the flawed process of investigation of scientific misconduct and premature conclusions of the outcomes are discussed.

Changes in risk profile and outcomes over 40 years were assessed from the Stanford experience with heart transplant in children. Age at transplant decreased in the most recent time period from about 10 to 5.6 years. The use of mechnical support as bridge increased dramatically over the time of the study. Long-term survival increased dramatically, and patients with cardiomyopathy had a survival advantage over those with congenital heart disease.

This study used a multicenter cohort in Italy to identify prognostic indicators for 3-year survival in patients who had undergone extrapleural pneumonectomy (EPP) for mesothelioma. 23% lived 3 years or longer. This survival was related to age, epitheliod histology, lack of asbestos exposure, and involved LN ratio. A risk score for survival was developed based on these factors.

This study from the Michigan Society of Thoracic and Cardiovascular Surgeons Quality Collaborative evaluated outcomes of CABG in 33 hospitals 2011-2013, assessing the association of blood transfusion (39.9% of pts) and the incidence of postoperative pneumonia (3.6% of pts). Blood transfusion was associated with an increased risk of pneumonia (OR 3.4), and there was a dose-response relationship between the number of units transfused and pneumonia risk.

Short- and mid-term outcomes of TAVR for nonagenarian (>90 years) patients in the PARTNER-1 trial were assessed for 531 pts. MACE occurred in 35% including stroke in 3.6%. Important paravalvular leak occurred in 1.4%. 30-day mortality was 4% and 3-year mortality was 48%, which compared to 44% in a matched population. QOL stabilized at 6 months and was better than preop. A trans-apical approach had a higher risk of 30-day and 3-year mortality.

Long-term outcomes of endovascular (EVAR) and open repair of abdominal aortic aneurysm (AAA) were compared using a California-based dataset including more than 23,000 pts. Postoperative outcomes were better with EVAR, and survival at 3 years was better with EVAR. After 3 years, mortality was higher for EVAR, and EVAR was associated with higher rates of reintervention and of late AAA rupture.

The authors of this study compared quality of life in patients at increased surgical risk who underwent either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Quality of life was assesed in 795 randomized patients using the Kansas City Cardiomyopathy Questionnaire, the Medical Outcomes Study Short-Form 12 Questionnaire, and EuroQOL 5-dimension questionnaire. They found that quality of life at 1 year was similar in the two groups. However, sooner after the procedure (1 month) there was a quality of life benefit of femoral TAVR compared with SAVR. This early benefit over SAVR was not seen in patients that were treated with non-iliofemoral TAVR.

Multicenter trial examining the efficacy of a miniaturized and fully self-contained leadless pacemaker percutaneously implanted into the right ventricle. The leadless pacemaker met prespecified pacing and sensing requirements with 1 in 15 patients experiencing adverse device related events.

Investigators from Stanford developed a nine-gene expression predictor for survival outcome in early-stage nonsquamous NSCLC. They developed and validated a quantitative real-time polymerase chain reaction assay easily applicable to routinely obtained paraffin-embedded tumor specimens. Because the molecular prognostic index provides independent prognostic information when compared with standard clinical and pathologic covariates (age, sex, and stage), the authors decided to combine both in order to create a more robust risk index. These findings will be useful for assessing recurrence risk for patients with nonsquamous NSCLC and could guide indications for adjuvant treatment in order to improve outcomes for high-risk patients.

Outcomes of robotic vs nonrobotic cardiac surgery were evaluated using 1:2 propensity score matching of patients in the Nationwide Inpatient Sample. Operations included valves/septae (10%), coronary arteries (47%), and other. Mean costs were 7.5% higher for robotic cases. Robotic procedures had shorter length of stay (5 vs 6 days), lower mortality (1.0% vs 1.9%), and fewer complications (27% vs 30%).
