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.

This insightful paper compares surgery for degenerative mitral valve disease over a number of different "eras." Interestingly, the most recent data in what the authors term "era 3" (2005-2011) demonstrates that patients are being operated on at an earlier stage in their disease- with less symptoms than historic eras. The in-hospital mortality, however, in this group of patients is at its lowest-ever: 0.043%. Whilst there, of course, will have been other confounders over the time periods investigated the authors explain that this data may demonstrate that earlier intervention in patients with degenerative mitral valve disease may be beneficial.

240 high risk patients undergoing cardiac surgery were randomized to remote ischemic preconditioning (3 5-min cycles of single upper extremity ischemia after anesthetic induction) or sham. Preconditioning reduced the incidence of acute kidney injury by one-third and the need for renal replacement therapy by two-thirds. These results were associated with changes in urinary insulinlike growth factor–binding protein 7 and tissue inhibitor of metalloproteinases 2. No differences were found between the groups for other major complications.
