This Swedish study was a retrospective review over a 20-year time period that compared survival after out-of-hospital cardiac arrest between those receiving bystander CPR prior to EMS arrival and those not receiving such. CPR before the arrival of EMS was associated with an increased 30-d survival rate (odds ratio 2.15; 95% CI 1.88-2.45).

In this manuscript the authors report on data from the German Aortic Valve Registry (GARY) comprising 15964 transcatheter aortic valve replacement (TAVR) procedures performed from 2011 to 2013 evaluating severe vital complications (SVCs), technical complications of the procedures (TCOs), other complications, conversion to sternotomy and in-hospital death. Patients’ mean age was 80.9 years. A balloon expandable prosthesis was used in 52.6% of the cases. An average 5% of the patients experienced SVCs, with a significant decrease in SVCs from 6.8% (in 2011) to 4.9% (in 2012) and 3.9% (in 2013). Residual aortic regurgitation was detected in 5.8% of patients. Need for pacemaker implantation occurred in 17.5% of patients. Stroke was diagnosed in 1.5%. Technical complications occurred in 748 patients (4.7%). Conversion to sternotomy was required in 201 patients (1.3%). Major vascular complications occurred in 4.1%. All these complications showed a significant decline in prevalence during the study period.
Logistic Euroscore and STS score were 18.3 and 5.0 respectively. A total of 828 patients (5.2%) died during the procedures or during the hospital stay. Interestingly, multivariate analysis showed that the transapical approach was not an independent predictor of death. The authors conclude that TAVR therapy is safe with acceptable complication rates (decreasing over time) in an all-comers and high-risk patient population.

In this open-access article, the authors describe their findings in a systematic review of transcatheter heart valve (THV) failures, comprising 70 articles and 87 individual cases. Unusual complications such as late embolization (mostly into the left ventricle) and prosthetic compression (exclusively in balloon expandable THVs) are described. Structural valve deterioration is reported in 13 cases, the most common cause being severe leaflet calcification. THV thrombosis has been documented in 10 publications comprising 15 patients (14 balloon expandable THV). The authors conclude that THV appear to be susceptible to failure modes both similar to those of surgical bioprosthetic valves and unique to the specific design features of THVs.

This meta-analysis of published studies evaluated outcomes of multimodality therapy including resection for superior sulcus NSCLC invading the spine. 134 articles were evaluated, which included 135 patients. 63% had induction therapy, and all underwent en bloc resection. 52% had adjuvant therapy. Survival at 3,5, and 10 years was 57%, 42%, and 27%. R0 resection was a predictor of survival.

Outcomes of esophagectomy, including in-hospital mortality and length of stay (LOS), were compared between England (centralized care) and the US (no centralized care). Data for 2005-2010 included 7433 esophagectomies performed in 66 hospitals in England and 5858 esophagectomies performed in 775 hospitals in the US. Morality was greater in the US (5.5% vs 4.2%; p=0.001). Predictors of mortality included age, comorbidities, hospital volume, and surgery in the US. Interestingly, in high volume hospitals mortality was lower in the US (2.1% vs 3.5%; p=0.02). LOS overall was greater in England; LOS decreased with increasing hospital volume in the US but not in England.

Laser-assisted fluorescent-dye angiography (LAA) was used prospectively in 150 patients undergoing esophagectomy with gastric pull-up to assess blood flow in the gastric tube. Anastomotic leak occured in 17%. Anastomoses performed in areas of normal perfusion had a 2% leak rate, compared to a 45% leak rate when anastomoses were performed in areas of poor perfusion.

During the last decade, the world of academic research and publication was attacked by low quality and commercial
journals that mimic the peer-reviewed scientific journals that I call this phenomenon “questionable journals” .
Later, fake conferences were scheduled and money was collected from authors, but the conferences never occurred
. Subsequently, the phenomenon of hijacked journals came into existence in October 2011, and I detected it in
early 2012 . The next phenomenon was the outbreak of fake publishers whose journals never appeared
anywhere . These journals had convincing sounding names, such as the Science Record Journals, the Thomas
Publications Journals (Thomaspub), and the Recent Science journals. However, the sad story continued, and in,
August 2013, I detected and reported five fake impact factor companies that claimed to calculate impact factors for
scientific journals. Indeed those impact factors were bogus metrics that were introduced to the academic world
by fake companies that were not registered anywhere by anyone. The purpose of this article is to provide some
more detailed information concerning how some of the fake impact factors and metrics came into existence and
infected the world of academic publishing.

The authors evaluated VATS vs pleural drainage for initial primary spontaneous pneumothorax in 122 pts, evaluating costs and QOL. Costs for VATS were half of those for pleural drainage. Quality adjusted life years were better for VATS. The incremental cost-effectiveness ratio for VATS was 7,600 euros at 1 year and 10,000 euros at 5 years, well within the acceptable range.

This single institution retrospective analysis of esophagectomy or gastrectomy for GEJ cancer compared outcomes between groups who did and did not complete recommended 2 cycles of postoperative adjuvant chemotherapy. Of 110 pts who underwent perioperative chemotherapy, 67% completed postoperative adjuvant chemotherapy. Completion of 2 cycles or more of postoperative adjuvent chemotherapy was associated with improved survival.
