While much investment has gone into developing interprofessional education (IPE) curriculum for healthcare professional students, many of these efforts have focused on classroom rather than clinical environments. Implementing robust IPE experiences into clinical training is often complicated by obstacles such as differing rotating schedules and differing curricular requirements. The Combined Medical-Physician Assistant Student Rural Rotation (Med-PARR) at the Oregon Health and Science University takes a practical approach to these challenges...

John Scott Haldane recognized that the administration of supplemental oxygen required titration in the individual. Although he made this observation in adults, it is equally applicable to the preterm newborn. But how, in practice, can the oxygen requirements in the preterm newborn be determined to avoid the consequences of too little and too much oxygen? Unfortunately, the current generation of oxygen saturation trials in preterm newborns guides saturation thresholds rather than individual oxygen requirements...

Super hybrid rice varieties with ideal plant architecture (IPA) have been critical in enhancing food security worldwide. However, the molecular mechanisms underlying their improved yield remain unclear. Here, we report the identification of a QTL, qWS8/ipa1-2D, in the super rice Yongyou12 (YY12) and related varieties. In-depth genetic molecular characterization of qWS8/ipa1-2D reveals that this newly identified QTL results from three distal naturally occurring tandem repeats upstream of IPA1, a key gene/locus previously shown to shape rice ideal plant architecture and greatly enhance grain yield...

BACKGROUND: Population-based net survival by tumour stage at diagnosis is a key measure in cancer surveillance. Unfortunately, data on tumour stage are often missing for a non-negligible proportion of patients and the mechanism giving rise to the missingness is usually anything but completely at random. In this setting, restricting analysis to the subset of complete records gives typically biased results. Multiple imputation is a promising practical approach to the issues raised by the missing data, but its use in conjunction with the Pohar-Perme method for estimating net survival has not been formally evaluated...

PURPOSE OF REVIEW: Here, we review current concepts on hypertensive crisis (HTN-C) with a focus on epidemiology, causes, pathophysiology and prognosis. We also offer a practical approach to the management of HTN-C. RECENT FINDINGS: HTN-C is characterized by a severe and abrupt increase in blood pressure (BP) with impending or progressive acute end-organ damage (EOD). HTN-C can be divided into hypertensive emergency (HTN-E) and hypertensive urgency (HTN-U) based on the presence or absence of acute EOD, respectively...

The understanding and treatment of multiple myeloma have dramatically improved in the last years. However, accurate assessment of the response of myeloma to therapy and its subsequent relapse remains a difficult task. Criteria have changed over time and new parameters have recently been incorporated to evaluate the minimal residual disease status. We present a practical approach to assess response and relapse/progression in myeloma in the context of its treatment. A robust reporting schema is crucial to correctly evaluate any treatment protocol and do cross trial comparisons...

The use of gene expression-based classifiers has resulted in a number of promising potential signatures of patient diagnosis, prognosis, and response to therapy. However, these approaches have also created difficulties in trying to use gene expression alone to predict a complex trait. A practical approach to this problem is to integrate existing biological knowledge with gene expression to build a composite predictor. We studied the problem of predicting radiation sensitivity within human cancer cell lines from gene expression...

Bovine β-lactoglobulin (BLG) is the main allergen in cows' milk, and the most commonly used method for detecting BLG is enzyme-linked immunosorbent assay (ELISA). However, antibodies used in commercial ELISA kits do not recognize specifically BLG IgE epitopes. Here, an antibody specific to IgE linear epitopes for BLG was used to develop a sandwich ELISA using a rabbit anti-BLG polyclonal antibody. The linear range for BLG detection was 31.25-8000ng/mL and limit of detection was 1.96ng/mL. BLG content in dairy samples was determined, and there was a good agreement between this immunoassay and reversed-phase high-performance liquid chromatography with high recovery...

Na Le Dang, Tyler B Hughes, Grover P Miller, S Joshua Swamidass
Structural alerts are commonly used in drug discovery to identify molecules likely to form reactive metabolites and thereby become toxic. Unfortunately, as useful as structural alerts are, they do not effectively model if, when, and why metabolism renders safe molecules toxic. Toxicity due to a specific structural alert is highly conditional, depending on the metabolism of the alert, the reactivity of its metabolites, dosage, and competing detoxification pathways. A systems approach, which explicitly models these pathways, could more effectively assess the toxicity risk of drug candidates...

Clinically, lymphomatoid papulosis (LYP) is characterized by recurrent papulonodular lesions. Unlike this stereotypical clinical presentation, the histological spectrum of LYP is very wide, comprising distinct growth patterns, variably sized neoplastic cells, and different immunophenotypes. The revised 2016 WHO classification includes the histological LYP types A to E as well as another type characterized by a specific chromosomal alteration. In addition, new LYP types are going to be proposed, based not only on histological but also on clinical and genetic features...

Cystic renal masses are a common entity with a wide differential diagnosis encountered by the radiologist in daily practice. Their characterization relies on the Bosniak classification system that has been widely accepted by radiologists and urologists as a pertinent diagnostic and communication tool. It has been designed to separate cystic lesions requiring surgery (categories III and IV) from those that can be ignored and left alone (categories I and II) or followed (category IIF). Utilization of the Bosniak classification requires, first, previous identification of the cystic nature of a renal mass with the exception of very small lesions...

The management of cancer in older aged people is becoming a common problem due to the aging of the population. There are many variables determining the complex situation that are interconnected. Some of them can be assessed, such as risk of mortality and risk of treatment complications, but many others are still unknown, such as the course of disease, the host-related factors that influence cancer aggressiveness, and the phenotype heralding risk of permanent treatment-related damage.This article presents a dynamic and personalized approach to older people with cancer based on our experience on aging, cancer, and their biological interactions...

BACKGROUND: End-of-life decision making constitutes a major challenge for bioethical deliberation and political governance in modern democracies: On the one hand, it touches upon fundamental convictions about life, death, and the human condition. On the other, it is deeply rooted in religious traditions and historical experiences and thus shows great socio-cultural diversity. The bioethical discussion of such cultural issues oscillates between liberal individualism and cultural stereotyping...

REVIEW
Boni E Elewski, Tracey C Vlahovic, Andrew Korotzer
Background: The current definition of complete cure is considered too stringent to reflect the true benefit of onychomycosis treatment seen in general practice and may limit the use of newer topical agents in mild-to-moderate disease. In addition, outcomes reported in clinical trials do not consistently report secondary endpoints, making data comparison difficult. Methods: The authors review the clinical data reported on two new topical antifungals, efinaconazole and tavaborole, in light of the latest thinking of more practical approaches to assess improvement and treatment success...

Adverse Outcome Pathways (AOPs) describe toxicant effects as a sequential chain of causally linked events beginning with a molecular perturbation and culminating in an adverse outcome at an individual or population level. Strategies for developing AOPs are still evolving and depend largely on the intended use or motivation for development and data availability. Four ecotoxicological AOP case studies, developed for different purposes, are described herein. In each situation, creation of the AOP began in a manner determined by the initial motivation for its creation, and expanded either to include additional components of the pathway, or to address the domains of applicability in terms of chemical initiators, susceptible species, life stages, etc...
