Strategies to empower the immune system to successfully attack cancers, including vaccination approaches, adaptive T cell therapies, and immune checkpoint modulators, have recently achieved remarkable success across a spectrum of cancer indications. Nonetheless, with rare exception, only a minority of patients with a given type of cancer respond to an immunotherapeutic when administered as single-agent therapy. Although under extensive laboratory and clinical investigation, the role of these approaches for glioma patients remains to be determined...

Objective: Problem list data is a driving force for many beneficial clinical tools, yet these data remain underutilized. We performed a systematic literature review, pulling insights from previous research, aggregating insights into themes, and distilling themes into actionable advice. We sought to learn what changes we could make to existing applications, to the clinical workflow, and to clinicians' perceptions that would improve problem list utilization and increase the prevalence of problems data in the electronic medical record...

Introduction: Military prehospital and en route care (ERC) directly impacts patient morbidity and mortality. Provider knowledge and skills are critical variables in the effectiveness of ERC. No Navy doctrine defines provider choice for patient transport or requires standardized provider training. Frequently, Search and Rescue Medical Technicians (SMTs) and Navy Nurses (ERC RNs) are tasked with this mission though physicians have also been used. Navy ERC provider training varies greatly by professional role...

Increasing access to early care and education (ECE) for children in the child welfare system (CWS) remains a critical issue in the United States, as the numbers of young children entering this system steadily increases. Mounting evidence suggests that participation in at least some types of ECE can mitigate the need for child welfare supervision. Moreover, ECE participation has been linked to positive developmental and school readiness outcomes, lower rates of foster placement, and greater placement stability for children in the CWS...

Contemporary research in the drugs field has demonstrated a number of gender differences in patterns and experiences of substance use, and the design and provision of gender-responsive interventions has been identified as an important policy issue. Consequently, whether and how domestic drug policies attend to women and gender issues is an important question for investigation. This article presents a policy audit and critical analysis of Australian national and state and territory policy documents. It identifies and discusses two key styles of problematisation of women's drug use in policy: 1) drug use and its effect on women's reproductive role (including a focus on pregnant women and women who are mothers), and 2) drug use and its relationship to women's vulnerability to harm (including violent and sexual victimisation, trauma, and mental health issues)...

BACKGROUND: Cisplatin has been used as a chemotherapeutic agent to treat many different cancers. A well-known side effect of cisplatin is nephrotoxicity, which is the primary dose-limiting toxicity. Hydration in conjunction with appropriate diuresis can decrease the incidence of nephrotoxicity. OBJECTIVES: This article aims to identify best practices in supportive therapy for patients receiving cisplatin therapy. METHODS: A team was assembled to review research-based evidence and summarize recommendations to address appropriate hydration regimens and forced diuresis for patients receiving cisplatin chemotherapy...

PURPOSE OF REVIEW: Since the first discovery of microRNAs (miRNAs) in 1993, the involvement of miRNAs in different aspects of vascular disease has emerged as an important research field. In this review, we summarize the fundamental roles of miRNAs in controlling endothelial cell functions and their implication with several aspects of vascular dysfunction. RECENT FINDINGS: MiRNAs have been found to be critical modulators of endothelial homeostasis. The dysregulation of miRNAs has been linked to endothelial dysfunction and the development and progression of vascular disease which and open new opportunities of using miRNAs as potential therapeutic targets for vascular disease...

BACKGROUND: Although more men than women sustain a traumatic brain injury (TBI), approximately one quarter of people with TBIs are women. The experiences of TBI reported in the literature are informed from the masculine perspective and do not adequately represent women's experiences. Pragmatism provides an overarching methodological framework to explore and critique a broader perspective of health, including psychosocial, cultural, spiritual, political and environmental factors, while attempting to address gender inequity...

BACKGROUND: There are three commonly known philosophical research paradigms used to guide research methods and analysis: positivism, interpretivism and critical theory. Being able to justify the decision to adopt or reject a philosophy should be part of the basis of research. It is therefore important to understand these paradigms, their origins and principles, and to decide which is appropriate for a study and inform its design, methodology and analysis. AIM: To help those new to research philosophy by explaining positivism, interpretivism and critical theory...

AIMS AND OBJECTIVES: To gain insight into nurses' knowledge and attitudes regarding major immobility complications (pressure ulcers, pneumonia, deep vein thrombosis and urinary tract infections) and explore the correlation of nurses' knowledge and attitudes with the incidence of these complications. BACKGROUND: Immobility complications have adverse consequences, and effective management requires appropriate knowledge, attitudes and skills. Evidence about nurses' knowledge and attitudes regarding immobility complications is lacking...

Eye gaze conveys rich information concerning the states of mind of others, playing a critical role in social interactions, signaling internal states, and guiding others' attention. On the basis of its social significance, some researchers have proposed that eye gaze may represent a unique attentional stimulus. However, contrary to this notion, the majority of the literature has shown indistinguishable attentional effects when eye gaze and arrows have been used as cues. Taking a different approach, in this study we aimed at finding qualitative attentional differences between gazes and arrows when they were used as targets instead of as cues...

Extracellular vesicles (EVs) comprise a heterogeneous group of small membrane vesicles, including exosomes, which play a critical role in intracellular communication and regulation of numerous physiological processes in health and disease. Naturally released from virtually all cells, these vesicles contain an array of nucleic acids, lipids and proteins which they transfer to target cells within their local milieu and systemically. They have been proposed as a means of "cell-free, cell therapy" for cancer, immune disorders, and more recently cardiovascular disease...

Surgical simulators are being increasingly used as an attractive alternative to clinical training in addition to conventional animal models and human specimens. Typically, surgical simulation technology is designed for the purpose of teaching technical surgical skills (so-called task trainers). Simulator training in surgery is therefore in general limited to the individual training of the surgeon and disregards the participation of the rest of the surgical team. The objective of the project Assessment and Training of Medical Experts based on Objective Standards (ATMEOS) is to develop an immersive simulated operating room environment that enables the training and assessment of multidisciplinary surgical teams under various conditions...

Drought is the major abiotic stress that decreases plant water status, inhibits photosynthesis, induces oxidative stress, restricts growth and finally lead to the reduction of wheat yield. It has been proven that drought priming during vegetative growth stage could enhance tolerance to drought stress at grain filling in wheat. However, whether drought priming imposed at grain filling in parental plants could induce drought tolerance in the offspring is not known. In this study, drought priming was successively applied in the first, the second and the third generation of wheat to obtain the plants of T1 (primed for one generation), T2 (primed for two generations), T3 (primed for three generations)...

There is often a divide between moral judgment and moral action; between what we believe we ought to do (or not do) and what we do. Knowledge of this divide is not new, and numerous theories have attempted to offer more robust accounts of ethical decision-making and moral functioning. Knowledge of widespread academic dishonesty among students is also not new, and several studies have revealed that many students report cheating despite believing it is wrong. The present study, involving cross-sectional survey data from a sample of secondary students ( N = 380) in the United States, contributes to the literature on this important area of theory and research by fulfilling three broad purposes...

High volume manufacturing of devices based on transition metal dichalcogenide (TMD) ultra-thin films will require deposition techniques that are capable of reproducible wafer-scale growth with monolayer control. To date, TMD growth efforts have largely relied upon sublimation and transport of solid precursors with minimal control over vapor phase flux and gas-phase chemistry, which are critical for scaling up laboratory processes to manufacturing settings. To address these issues, we report a new pulsed metalorganic chemical vapor deposition (MOCVD) route for MoS2 film growth in a research-grade single-wafer reactor...

Defining the metabolic strategies used by wheat to tolerate and recover from drought events will be important for ensuring yield stability in the future, but studies addressing this critical research topic are limited. To this end, the current study quantified the physiological, biochemical, and agronomic responses of a drought tolerant and drought sensitive cultivar to periods of water deficit and recovery. Drought stress caused a reversible decline in leaf water relations, membrane stability, and photosynthetic activity, leading to increased reactive oxygen species (ROS) generation, lipid peroxidation and membrane injury...

BACKGROUND AND OBJECTIVES: Incidence of ESKD is three times higher in black Americans than in whites, and CKD prevalence continues to rise among black Americans. Community-based kidney disease screening may increase early identification and awareness of black Americans at risk, but it is challenging to implement. This study aimed to identify participants' perspectives of community kidney disease screening. The Health Belief Model provides a theoretic framework for conceptualization of these perspectives and optimization of community kidney disease screening activities...

The study of parathyroid hyperplasia with bone disease as a critical manifestation of chronic kidney disease-mineral and bone disorders (CKD-MBDs) is challenging due to the lack of a suitable research model. Here, we established a rat model with secondary hyperparathyroidism (SHPT) and bone disease induced by adenine and a high phosphorous diet and analyzed the skeletal characteristics. We performed blood analysis, emission computed tomography (ECT), dual energy X-ray absorptiometry (DEXA), micro-computed tomography (micro-CT), bone histomorphometry, and bone mechanical tests...
