Delivering Patient Value by Using Process Improvement Tools to Decrease Patient Wait Time in an Outpatient Oncology Infusion Unit.

Purpose: This study aimed to streamline workflow from arrival to premedication by decreasing patient wait time to increase value in a high-volume academic outpatient oncology infusion unit. The streamlining process involved identifying and prioritizing patients for treatment by driving out waste in patient flow.

Methods: The plan-do-check-act (PDCA) method and Lean Methodology were used in completing a project to streamline a defined subset of patient experiences within an outpatient oncology infusion unit in an academic comprehensive cancer center.

Bayesian regression models outperform partial least squares methods for predicting milk components and technological properties using infrared spectral data.

The aim of this study was to assess the performance of Bayesian models commonly used for genomic selection to predict "difficult-to-predict" dairy traits, such as milk fatty acid (FA) expressed as percentage of total fatty acids, and technological properties, such as fresh cheese yield and protein recovery, using Fourier-transform infrared (FTIR) spectral data. Our main hypothesis was that Bayesian models that can estimate shrinkage and perform variable selection may improve our ability to predict FA traits and technological traits above and beyond what can be achieved using the current calibration models (e.g.

Genetic Control of Environmental Variation of Two Quantitative Traits of Drosophila melanogaster Revealed by Whole-Genome Sequencing.

Genetic studies usually focus on quantifying and understanding the existence of genetic control on expected phenotypic outcomes. However, there is compelling evidence suggesting the existence of genetic control at the level of environmental variability, with some genotypes exhibiting more stable and others more volatile performance. Understanding the mechanisms responsible for environmental variability not only informs medical questions but is relevant in evolution and in agricultural science.

Neuroactive compounds obtained from arthropod venoms as new therapeutic platforms for the treatment of neurological disorders.

The impact of neurological disorders in society is growing with alarming estimations for an incidence increase in the next decades. These disorders are generally chronic and can affect individuals early during productive life, imposing real limitations on the performance of their social roles. Patients can have their independence, autonomy, freedom, self-image, and self-confidence affected.

Do Molecular Markers Inform About Pleiotropy?

The availability of dense panels of common single-nucleotide polymorphisms and sequence variants has facilitated the study of statistical features of the genetic architecture of complex traits and diseases via whole-genome regressions (WGRs). At the onset, traits were analyzed trait by trait, but recently, WGRs have been extended for analysis of several traits jointly. The expectation is that such an approach would offer insight into mechanisms that cause trait associations, such as pleiotropy.

The Effect of Route of Anvil Insertion on Stricture Rates with Circular Stapled Gastrojejunostomy During Laparoscopic Gastric Bypass.

Background: A higher incidence of gastrojejunal (GJ) anastomotic strictures has been reported following laparoscopic gastric bypass (LRYGB) with the 21 mm compared to 25 mm circular stapler. We hypothesized that the rate of stricture formation is affected by route of anvil insertion and its position relative to the gastric pouch staple line [trans-gastric above staple line (trans-gastric) vs. trans-oral through staple line (trans-oral)] following LRYGB.

Qualitative analysis of the vaginal microbiota of healthy cattle and cattle with genital-tract disease.

The microbial community of the reproductive appara-tus, when known, can provide information about the health of the host. Metagenomics has been used to characterize and obtain genetic infor-mation about microbial communities in various environments and can relate certain diseases with changes in this community composition. In this study, samples of vaginal surface mucosal secretions were col-lected from five healthy cows and five cows that showed symptoms of reproductive disorders.

Assessment of Genetic Heterogeneity in Structured Plant Populations Using Multivariate Whole-Genome Regression Models.

Plant breeding populations exhibit varying levels of structure and admixture; these features are likely to induce heterogeneity of marker effects across subpopulations. Traditionally, structure has been dealt with as a potential confounder, and various methods exist to "correct" for population stratification. However, these methods induce a mean correction that does not account for heterogeneity of marker effects.

The influence of pretreatment methods on saccharification of sugarcane bagasse by an enzyme extract from Chrysoporthe cubensis and commercial cocktails: A comparative study.

Biomass enzymatic hydrolysis depends on the pretreatment methods employed, the composition of initial feedstock and the enzyme cocktail used to release sugars for subsequent fermentation into ethanol. In this study, sugarcane bagasse was pretreated with 1% H2SO4 and 1% NaOH and the biomass saccharification was performed with 8% solids loading using 10 FPase units/g of bagasse of the enzymatic extract from Chrysoporthe cubensis and three commercial cocktails for a comparative study. Overall, the best glucose and xylose release was obtained from alkaline pretreated sugarcane bagasse.

Placebo effect in osteoarthritis: Why not use it to our advantage?

Osteoarthritis is a major cause of pain and reduced quality of life in the elderly, as well as a major economic burden. Unfortunately, there is no currently effective therapeutic strategy to prevent the progression of Osteoarthritis, and its treatment poses a great challenge to the medical community. Most of the treatment modalities currently available for osteoarthritis have small to moderate effect sizes, according to main meta-analyses and treatment guidelines.

Updated systematic review and meta-analysis of randomized controlled trials comparing low- versus high-dose rituximab for rheumatoid arthritis.

The purpose of this study is to update a systematic review and meta-analysis comparing low- (2 × 500 or 1 × 1000 mg) and high-dose (2 × 1000 mg) rituximab (RTX) for the treatment of rheumatoid arthritis (RA), considering the recent emergence of new evidence. The systematic literature review searching for randomized controlled trials (RCTs) was updated to November 6, 2014 using the PubMed, EMBASE, Cochrane Library, Web of Science databases, and hand searching. The primary outcomes were the American College of Rheumatology (ACR) criteria for 20 % improvement (ACR20), ACR50, and ACR70 responses and the Disease Activity Score in 28 joints (DAS28) at 24 and 48/52 weeks.

Human bocavirus in acute gastroenteritis in children in Brazil.

Epidemiological surveillance for Human Bocavirus (HBoV) was conducted on 105 fecal specimens from children with acute gastroenteritis in Bahia, Brazil. Among of a total 105 stool samples, 44 samples were positive for HBoV as detected by nested-PCR. Of the 44 positive samples, co-infections with other enteric viruses (Norovirus, Adenovirus, and Rotavirus) were found in 12 pediatric patients.

Reduction of surgical site infections after laparoscopic gastric bypass with circular stapled gastrojejunostomy.

Background: Circular stapled gastrojejunostomy (GJ) is favored by many surgeons during laparoscopic Roux-en-Y gastric bypass (LRYGB). However, it has been associated with higher rates of surgical site infection (SSI).

Objectives: To study the impact of introducing standard technical modifications (intervention) on the incidence of SSI after LRYGB with circular stapled GJ.

Feasibility and outcomes of laparoscopic sleeve gastrectomy after solid organ transplantation.

Background: Obesity is common after solid organ transplantation and is associated with worse transplantation-related outcomes. Laparoscopic sleeve gastrectomy (LSG) may be the preferred bariatric operation in transplantation patients over other techniques, such as gastric bypass, given the concerns about medication absorption. However, little is known about LSG outcomes in post-transplantation patients.

Gene networks and transcription factor motifs defining the differentiation of stem cells into hepatocyte-like cells.

Background & Aims: The differentiation of stem cells to hepatocyte-like cells (HLC) offers the perspective of unlimited supply of human hepatocytes. However, the degree of differentiation of HLC remains controversial. To obtain an unbiased characterization, we performed a transcriptomic study with HLC derived from human embryonic and induced stem cells (ESC, hiPSC) from three different laboratories.

Electroconvulsive therapy as a treatment for refractory neuropsychiatric lupus with catatonia: three case studies and literature review.

Neuropsychiatric disorders associated with systemic lupus erythematosus are very common. Treatment generally consists of glucocorticoids and immunosuppressive therapy; however, some cases are unresponsive. Electroconvulsive therapy (ECT) is a recognized treatment modality in psychiatry and is an option for refractory cases of neuropsychiatric lupus.

Preoperative assessment and classification of benign laryngotracheal stenosis: a consensus paper of the European Laryngological Society.

Adult and pediatric laryngotracheal stenoses (LTS) comprise a wide array of various conditions that require precise preoperative assessment and classification to improve comparison of different therapeutic modalities in a matched series of patients. This consensus paper of the European Laryngological Society proposes a five-step endoscopic airway assessment and a standardized reporting system to better differentiate fresh, incipient from mature, cicatricial LTSs, simple one-level from complex multilevel LTSs and finally "healthy" from "severely morbid" patients. The proposed scoring system, which integrates all of these parameters, may be used to help define different groups of LTS patients, choose the best treatment modality for each individual patient and assess distinct post-treatment outcomes accordingly.

Genomic heritability: what is it?

Whole-genome regression methods are being increasingly used for the analysis and prediction of complex traits and diseases. In human genetics, these methods are commonly used for inferences about genetic parameters, such as the amount of genetic variance among individuals or the proportion of phenotypic variance that can be explained by regression on molecular markers. This is so even though some of the assumptions commonly adopted for data analysis are at odds with important quantitative genetic concepts.

Dietary and psych predictors of weight loss after gastric bypass.

Background: Identifying severely obese patients who will succeed after bariatric surgery remains challenging. Although numerous studies have attempted to identify preoperative patient characteristics associated with weight loss, the roles of many dietary and psychological characteristics are unclear. The purpose of this study was to examine preoperative dietary and psychological predictors of successful weight loss after bariatric surgery.
