To evaluate the benefit of multimodality treatment for patients with limited disease small-cell lung cancer, Weckler and colleagues retrospectively reviewed outcomes for 47 patients treated at their institution between 1999 and 2016. Patients had undergone primary tumor resection and systematic lymph node dissection combined with chemotherapy, chemoradiotherapy, or thoracic radiotherapy, and all patients were treated with curative intent. Overall median survival was 56 months, and R0 resection was the only significant prognostic factor for survival. The authors conclude that multimodality treatment was safe, and that R0 resection was achievable with a low risk of locoregional relapse.

Given that acute kidney injury (AKI) after cardiac surgery is a risk factor for readmission, Brown and colleagues sought to determine whether urinary biomarkers were better at predicting readmission within 30 days that duration of AKI during the index admission. Using data from patients enrolled in the Translational Research Investigating Biomarker Endpoints-AKI trial, preoperative and postoperative levels of interleukin-18, neutrophil gelatinase–associated lipocalin, kidney injury molecule-1, liver-fatty-acid-binding protein, cystatin C, microalbumin, creatinine, and albumin-to-creatinine ratio were compared with the total number of days that AKI was present during the initial hospitalization. AKI duration of 3 to 6 days was associated with 30-day readmission or death (adjusted odds ratio, 1.82%; 95% confidence interval, 1.08 - 3.05), while urinary biomarkers had no association with readmission and death.

Food for thought from a retrospective non-randomized study on the Scandinavian experience with acute aortic dissection. The reader may find outcomes that will surpise them.

In this retrospective review of the effects of radiation dose to the heart on long-term outcomes, 748 patients with regionally advanced non–small cell lung cancer were studied.  An increasing cardiac radiotherapy dose was associated with an increased risk of MACE and all-cause mortality. This was observed primarily in patients without preexisting heart disease.

Leonard L. Bailey, a pediatric surgeon who attracted international attention in 1984 when he transplanted a baboon’s heart into a newborn human — “Baby Fae” — a medical moon shot that sparked breathless controversy but was credited with demonstrating the lifesaving potential of organ transplants for the tiniest patients, died May 12 at his home in Redlands, California. He was 76.

A new study looking a dietary protein sources and LDL cholesterol levels calls into question the idea that white meat is more heart healthy than red meat.

An expert consensus document on cardiogenic shock provides a standardized vocabulary for diagnosis and outlines best practices for treating patients.


Drugs and Devices

A US Food and Drug Administration panel recommended reclassifying surgical staplers to class II medical devices as the agency acknowledged a greater number of device malfunction reports than had been publicly disclosed.

The European Respiratory Society says that the strategy of tobacco harm reduction using e-cigarettes should not be used as a population-based approach for tobacco control, citing a lack of evidence that they reduce nicotine dependence and the potential for health risks that are not yet known.

In related news, researchers from the UK report that e-cigarettes improved rates of tobacco cessation, while researchers from the US find that e-cigarette flavorings have negative effects on endothelial cell function.

Researchers at Imperial College London in the UK have developed a small patch of stem cells that can be sewn to the heart, and in rabbits the patches integrated and improved heart function after experimental myocardial infarction.

Interim results from a trial on immune checkpoint inhibitors given before surgery to patients with resectable lung cancer suggest the treatment was well-tolerated and may provide benefit to these patients.

The treatment approaches and in-hospital outcomes were analyzed for 885,806 patients with acute pulmonary embolism (PE) in Germany between 2005 and 2015. The incidence of acute PE increased from 85 per 100,000 in 2005 to 109 per 100,000 in 2015 [β 0.32 (0.26–0.38), P < 0.001]. During the same period, in-hospital case fatality rates decreased from 20.4% to 13.9% [β −0.51 (−0.52 to −0.49), P < 0.001]. The overall proportion of patients treated with systemic thrombolysis increased from 3.1% in 2005 to 4.4% in 2015 [β 0.28 (0.25–0.31), P < 0.001]. Thrombolysis was associated with lower in-hospital mortality rates in patients with hemodynamic instability, both in those with shock not necessitating cardiopulmonary resuscitation (CPR) or mechanical ventilation [odds ratio (OR) 0.42 (0.37–0.48), P < 0.001], and in patients who underwent CPR [OR 0.92 (0.87–0.97), P = 0.002]. This association was independent of age, sex, and comorbidities. However, systemic thrombolysis was administered to only 23.1% of hemodynamically unstable patients.

As the procedure began, doctors found that one lung was stuck to the chest bone forming bullae, which are like blisters and often occur with COPD. The surgeons punctured one of the blisters, causing an air leak. So that the patient wouldn't have trouble breathing, the anesthesiologist increased the amount of oxygen.

Fed by leaking oxygen, a spark from an electrocautery device set a dry surgical pack on fire. Doctors immediately put the fire out and continued with the procedure, successfully repairing the torn artery. The findings were presented at the 2019 European Society of Anesthesiology meeting in Vienna, Austria.

Left ventricular ejection fraction was not a predictor of outcomes after heart transplant, and was normal in all recipients at 1 year posttransplant. The reliance on generic transthoracic echocardiography for donor assessment may well be the Achilles heel of this retrospective case study.
