Does surgical procedure type impact postoperative pain and recovery in deep inferior epigastric artery perforator flap breast reconstruction?

Background: The deep inferior epigastric artery perforator (DIEP) flap is the commonest flap used for breast reconstruction after mastectomy. It is performed as a unilateral (based on one [unipedicled] or two [bipedicled] vascular pedicles) or bilateral procedure following unilateral or bilateral mastectomies. No previous studies have comprehensively analyzed analgesia requirements and hospital stay of these three forms of surgical reconstruction. Methods: A 7-year retrospective cohort study (2008–2015) of a single-surgeon’s DIEP-patients was conducted. Patient-reported pain scores, patient-controlled morphine requirements and recovery times were compared using non-parametric statistics and multivariable regression. Results: The study included 135 participants: unilateral unipedicled (n=84), unilateral bipedicled (n=24) and bilateral unipedicled (n=27). Univariate comparison of the three DIEP types showed a significant difference in 12-hour postoperative morphine requirements (P=0.020); bipedicled unilateral patients used significantly less morphine than unipedicled (unilateral) patients at 12 (P=0.005), 24 (P=0.020), and 48 (P=0.046) hours. Multivariable regression comparing these two groups revealed that both reconstruction type and smoking status were significant predictors for 12-hour postoperative morphine usage (P=0.038 and P=0.049, respectively), but only smoking, remained significant at 24 (P=0.010) and 48 (P=0.010) hours. Bilateral reconstruction patients’ mean hospital stay was 2 days longer than either unilateral reconstruction (P<0.001). Conclusions: Although all three forms of DIEP flap breast reconstruction had similar postoperative pain measures, a novel finding of our study was that bipedicled DIEP flap harvest might be associated with lower early postoperative morphine requirements. Bilateral and bipedicled procedures in appropriate patients might therefore be undertaken without significantly increased pain/morbidity compared to unilateral unipedicled reconstructions

Genetic structure of community acquired methicillin-resistant Staphylococcus aureus USA300.

BackgroundCommunity-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is a significant bacterial pathogen that poses considerable clinical and public health challenges. The majority of the CA-MRSA disease burden consists of skin and soft tissue infections (SSTI) not associated with significant morbidity; however, CA-MRSA also causes severe, invasive infections resulting in significant morbidity and mortality. The broad range of disease severity may be influenced by bacterial genetic variation.ResultsWe sequenced the complete genomes of 36 CA-MRSA clinical isolates from the predominant North American community acquired clonal type USA300 (18 SSTI and 18 severe infection-associated isolates). While all 36 isolates shared remarkable genetic similarity, we found greater overall time-dependent sequence diversity among SSTI isolates. In addition, pathway analysis of non-synonymous variations revealed increased sequence diversity in the putative virulence genes of SSTI isolates.ConclusionsHere we report the first whole genome survey of diverse clinical isolates of the USA300 lineage and describe the evolution of the pathogen over time within a defined geographic area. The results demonstrate the close relatedness of clinically independent CA-MRSA isolates, which carry implications for understanding CA-MRSA epidemiology and combating its spread

Behind the Kitchen Door

[Excerpt] How do restaurant workers live on some of the lowest wages in America? And how do poor working conditions - discriminatory labor practices, exploitation, and unsanitary kitchens - affect the meals that arrive at our restaurant tables? Saru Jayaraman, who launched the national restaurant workers\u27 organization Restaurant Opportunities Centers United, sets out to answer these questions by following the lives of restaurant workers in New York City, Washington, D.C., Philadelphia, Houston, Los Angeles, Miami, Detroit, and New Orleans
