Effectiveness of intensive primary care interventions: a systematic review.
This study systematically reviewed the impact of intensive primary care programs on all-cause mortality, hospitalization, and emergency department use. The authors found that intensive primary care interventions demonstrated varying effectiveness in reducing hospitalizations, and noted there was limited evidence that these interventions were associated with changes in mortality.

Neoadjuvant radiotherapy is associated with R0 resection and improved survival for patients with extremity soft tissue sarcoma undergoing surgery: a national cancer database analysis.
Neoadjuvant radiotherapy (RT) is increasingly advocated for the management of soft tissue sarcoma (STS). This study sought to characterize the impact of neoadjuvant RT on rates of R0 resection and overall survival (OS) in extremity STS patients undergoing surgery. The authors concluded that preoperative RT independently predicts higher rates of R0 resection for patients with extremity STS undergoing surgical resection. Negative surgical margins and pre- or postoperative RT are associated with improved OS.

Reexamining the association of body mass index with overall survival outcomes after liver transplantation.
The purpose of this study is to identify the range of body mass index (BMI) at liver transplantation (LT) associated with the lowest risks of posttransplant mortality by Model of End Stage Liver Disease (MELD) category. It concluded that obesity in LT patients is not necessarily associated with higher posttransplantation mortality and highlighted the importance of the interaction between BMI and MELD category to determine their survival likelihood.

Revisiting a longstanding clinical trial exclusion criterion: impact of prior cancer in early-stage lung cancer.
The researchers examined the prevalence and prognostic impact of a prior cancer diagnosis among patients with early-stage lung cancer. They found no difference in all-cause survival between patients with and without prior cancer. Lung cancer specific survival was improved among patients with prior cancer.

Survival gains from first-line systemic therapy in metastatic non-small cell lung cancer in the U.S., 1990-2015: progress and opportunities.
The objectives of this study were to quantify survival gains from 1990, when best supportive care only was standard, to 2015 and to estimate the impact of expanded use of new systemic therapies in clinically appropriate patients. By using simulation modeling to quantify metastatic non-small cell lung cancer survival gains from 1990-2015, the researchers estimated that the one-year survival proportion and mean per-patient survival increased by 14.1 percent and 4.2 months, respectively.

The role of extended criteria donors in liver transplantation for nonalcoholic steatohepatitis.
The authors' objective was to determine the use of extended criteria donors (ECD) in patients with nonalcoholic steatohepatitis undergoing liver transplantation to stimulate a liver-specific predictive model for ECD use. They found that ECDs in nonalcoholic steatohepatitis were associated with similar overall survival but increased risk of graft failure. The authors concluded that creation of an easily calculated, liver-specific model similar to the Kidney Donor Profile Index may help risk stratify patients and improve organ allocation.

The effect of substance use disorders on the association between guideline-concordant long-term opioid therapy and all-cause mortality.
The objective of this study was to determine whether the presence of a substance use disorder (SUD) modifies the association between guideline-concordant care and 1-year all-cause mortality among patients receiving long-term opioid therapy (LtOT) for pain. It found that for clinicians prescribing LtOT to patients with untreated SUDs, engaging patients with psychotherapeutic and SUD treatment services may reduce mortality.

Hospital case volume is associated with improved survival for patients with metastatic melanoma.
This study investigated the influence of hospital case volume on malignant melanoma survival and treatment utilization. The researchers discovered that for patients diagnosed with metastatic melanoma, being treated in a high-volume hospital was associated with an improvement in survival and lower utilization of chemotherapy, immunotherapy, surgery, and radiation therapy.

Prior cancer does not adversely affect survival in locally advanced lung cancer: a national SEER-Medicare analysis.
Researchers identified patients > 65 years of age diagnosed 1992-2009 with locally advanced lung cancer in the Surveillance, Epidemiology, and End Results-Medicare linked dataset. They found that, for patients with locally advanced lung cancer, prior cancer does not adversely impact clinical outcomes. Patients with locally advanced lung cancer and a history of prior cancer should not be excluded from clinical trials.

The association between receipt of guideline-concordant long-term opioid therapy and all-cause mortality.
The researchers' objective was to determine the association between receipt of guideline-concordant long-term opioid therapy (LtOT) and 1-year all-cause mortality. They found no association between all-cause mortality and primary care visits or urine drug testing and recommended that providers use caution in initiating LtOT in conjunction with benzodiazepines and untreated substance use disorders.

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. In experienced hands, the rates of complications after pancreatectomy in patients 80 years or older compared to patients younger than 80 years were similar. However, when complications occurred, older patients were more likely to die.

Resource use in the last year of life among patients who died with versus of prostate cancer.
The researchers conducted a retrospective analysis of Surveillance, Epidemiology, and End Results-Medicare data of men with prostate cancer. Patients who died of prostate cancer rather than from other causes had more hospice and outpatient use, less inpatient and ICU use, and lower overall costs. Efforts to shift care toward outpatient settings might provide more efficient and judicious care for patients during the end of life.

Digoxin use is associated with reduced interstage mortality in patients with no history of arrhythmia after stage I palliation for single ventricle heart disease.
The researchers sought to determine whether digoxin use post-S1P is associated with reduced interstage mortality (IM), utilizing the multicenter database of the National Pediatric Cardiology Quality Improvement Collaborative (NPCQIC). They found that among infants with single vetricle defects in the NPCQIC database discharged post-S1P with no history of arrhythmia, use of digoxin at discharge was associated with reduced IM.

Early mortality after aortic valve replacement with mechanical prosthetic vs bioprosthetic valves among Medicare beneficiaries: a population-based cohort study.
The researchers compared early mortality after aortic valve replacement (AVR) between the recipients of mechanical and bioprosthetic aortic valves. Among 66,453 Medicare beneficiaries who received AVRs, use of mechanical valves was associated with a higher risk for death on the date of surgery and within 30 days compared with the bioprosthetic aortic valves. However, this applied only to those who underwent concurrent AVR and coronary artery bypass graft but not isolated AVR.

Outcomes of patients with healthcare-associated pneumonia: worse disease or sicker patients?
The researchers sought to determine the contribution of healthcare-associated pneumonia (HCAP) criteria to case-fatality rate. They found that, after adjustment for differences in patient characteristics, HCAP was associated with greater case-fatality rate than community-acquired pneumonia, possibly due to HCAP organisms or to HCAP criteria themselves.

Severity-adjusted mortality in trauma patients transported by police.
Two decades ago, Philadelphia began allowing police transport of patients with penetrating trauma. In this retrospective cohort study, the investigators conduct a large, multiyear, citywide analysis of this policy. They examine the association between mode of out-of-hospital transport (police department versus emergency medical services [EMS]) and mortality among patients with penetrating trauma in Philadelphia.
