Seminal plasma is a fluid that originates from the testis, epididymis,prostate, and seminal vesicles, and hence, proteomic studies may identify potential markers of infertility and other diseases of the genito-urinary tract. We profiled the proteomes of pooled seminal plasma from fertile Control and post-vasectomy (PV) men. PV seminal plasma samples are void of proteins originating from the testis and the epididymis due to ligation of the vas deferens, and hence, comparative analysis of Control and PV data sets allows for identification of proteins originating from these tissues. Utilizing offline MudPIT and high-resolution mass spectrometry, we were able to identify over 2000 proteins in Control and PV pools each and over 2300 proteins all together. With semiquantitative analysis using spectral counting, we catalogued 32 proteins unique to Control, 49 at lower abundance in PV, 3 unique to PV, and 25 at higher abundance in PV. We believe that proteins unique to Control or at lower abundance in PV have their origin in the testis and the epididymis. Public databases have confirmed that many of these proteins originate from the testis and epididymis and are linked to the reproductive tract. These proteins may serve as candidate biomarkers for future studies of infertility and urogenital diseases.

Evidence indicates that ERAS protocols may be implemented in pancreatic surgery without compromising patient safety or increasing LoS. Enhanced recovery after surgery programmes in the context of pancreatic surgery should be standardized based upon the best available evidence, and trials of ERAS programmes involving multiple centres should be performed.

Background: Red blood cell transfusions (RBCT) carry risk of transfusion-related immunodulation that may impact postoperative recovery. This study examined the association between perioperative RBCT and short-term postoperative outcomes following gastrectomy for gastric cancer. Methods:Using the American College of Surgeons National Surgical Quality Improvement Program database, we compared outcomes of patients (transfused v. nontransfused) undergoing elective gastrectomy for gastric cancer (2007)(2008)(2009)(2010)(2011)(2012). Outcomes were 30-day major morbidity, mortality and length of stay. The association between perioperative RBCT and outcomes was estimated using modified Poisson, logistic, or negative binomial regression. Results:Of the 3243 patients in the entire cohort, we included 2884 patients with nonmissing data, of whom 535 (18.6%) received RBCT. Overall 30-day major morbidity and mortality were 20% and 3.5%, respectively. After adjustment for baseline and clinical characteristics, RBCT was independently associated with increased 30-day mortality (relative risk [RR] 3.1, 95% confidence interval [CI] 1.9-5.0), major morbidity (RR 1.4, 95% CI 1.2-1.8), length of stay (RR 1.2, 95% CI 1.1-1.2), infections (RR 1.4, 95% CI 1.1-1.6), cardiac complications (RR 1.8, 95% CI 1.0-3.2) and respiratory failure (RR 2.3, 95% CI 1.6-3.3). Conclusion:Red blood cell transfusions are associated with worse postoperative short-term outcomes in patients with gastric cancer. Blood management strategies are needed to reduce the use of RBCT after gastrectomy for gastric cancer.Contexte : Les transfusion de globules rouges (TGR) entrainent une immunosuppression qui peut entraver la récupération post-opératoire. Cette étude évalue l'association entre les TGR péri-opératoires et l'issue post-opératoire après gastrectomie pour cancer gastrique (CG). Conclusion :Les TGR sont associées à une détérioration de l'issue post-opératoire après gastrectomie pour CG, dont la morbidité majeure, la mortalité, et la durée d'hospitalisation. Des stratégies multidisciplinaires de gestion du risque transfusionnel sont nécessaires afin de limiter l'utilisation des TGRs après gastrectomie pour CG.

Background: Prostatitis is an inflammation of the prostate gland which affects approximately 10% of men. Despite its frequency, diagnosing prostatitis and monitoring patient response to treatment remains frustrating. As the prostate contributes a substantial percentage of proteins to seminal plasma, we hypothesized that a protein biomarker of prostatitis might be found by comparing the seminal plasma proteome of patients with and without prostatitis. Results: Using mass spectrometry, we identified 1708 proteins in the pooled seminal plasma of 5 prostatitis patients. Comparing this list to a previously published list of seminal plasma proteins in the pooled seminal plasma of 5 healthy, fertile controls yielded 1464 proteins in common, 413 found only in the control group, and 254 found only in the prostatitis group. Applying a set of criteria to this dataset, we generated a high-confidence list of 59 candidate prostatitis biomarkers, 33 of which were significantly increased in prostatitis as compared to control, and 26 of which were decreased. The candidates were analyzed using Gene Ontology and Ingenuity Pathway analysis to delineate their subcellular localizations and functions.

Sociodemographic marginalization exerts its influence early in the pancreatic cancer care continuum, and appears to be associated more with which patients undergo surgical resection than the receipt of adjuvant treatment. Cancer 2016;122:3175-82. © 2016 American Cancer Society.

CPWs may generate cost savings by reducing unnecessary investigations, and improve quality of care through process standardization and decreasing practice variation.

Pasireotide appears to be a cost-saving treatment following PD across a wide variation of clinical and cost scenarios.

Progressive increases in hospital volume correspond to improved 90-day outcomes following PD.
