Increasing exercise capacity and physical activity in the COPD patient.

Higher levels of exercise capacity and physical activity are desired outcomes in the comprehensive management of the COPD patient. In addition, improvements in exercise capacity and physical activity are instrumental to optimising other important therapeutic goals, such as improved health status, reduced healthcare utilisation and increased survival. Four general approaches towards increasing exercise capacity and physical activity in individuals with COPD will be discussed in this review: 1) pharmacological intervention, especially the administration of long-acting bronchodilators; 2) pulmonary rehabilitation, including exercise training and collaborative self-management; 3) behavioural interventions; and 4) web-based interventions.

Test-Retest Reliability of the Verran Professional Governance Scale.

Stability testing, conducted using a test-retest protocol, measures an instrument's reliability by evaluating the consistency of participant responses to survey questions with repeated testing within a short interval. No studies have measured the stability of the Verran Professional Governance Scale (VPGS). The purpose of this study was to evaluate the test-retest reliability of the VPGS.

Trade-Offs in the Sensory Brain between Diurnal and Nocturnal Rodents.

Introduction: Transitions in temporal niche have occurred many times over the course of mammalian evolution. These are associated with changes in sensory stimuli available to animals, particularly with visual cues, because levels of light are so much higher during the day than at night. This relationship between temporal niche and available sensory stimuli elicits the expectation that evolutionary transitions between diurnal and nocturnal lifestyles will be accompanied by modifications of sensory systems that optimize the ability of animals to receive, process, and react to important stimuli in the environment.

Racial and ethnic disparities in postpartum weight retention: A narrative review mapping the literature to the National Institute on Minority Health and Health Disparities Research Framework.

Plain Language Summary: A Review of the Literature Using the National Institutes of Health, National Institute on Minority Health and Health Disparities (NIMHD) Research Framework to Create a Roadmap of the Studies Investigating Racial and Ethnic Disparities in Excess Weight Retained After Pregnancy.

Why Was This Study Done?: Three out of four people who give birth retain excess weight at 1-year post-pregnancy. This is concerning, as weight that is retained following pregnancy is associated with increased risk for the development of disease.

Testing of a novel questionnaire of Household Exposure to Wood Smoke.

Household air pollution from wood smoke (WS), contributes to adverse health effects in both low- and high-income countries. However, measurement of WS exposure has been limited to expensive in-home monitoring and lengthy face-to-face interviews. This paper reports on the development and testing of a novel, self-report nine-item measure of WS exposure, called the Household Exposure to Wood Smoke (HEWS).

COPD: Providing the right treatment for the right patient at the right time.

Chronic Obstructive Pulmonary Disease (COPD) is a common disease associated with significant morbidity and mortality that is both preventable and treatable. However, a major challenge in recognizing, preventing, and treating COPD is understanding its complexity. While COPD has historically been characterized as a disease defined by airflow limitation, we now understand it as a multi-component disease with many clinical phenotypes, systemic manifestations, and associated co-morbidities.

Cleaning the Flue in Wood-Burning Stoves Is a Key Factor in Reducing Household Air Pollution.

In experimental settings, replacing old wood stoves with new wood stoves results in reduced personal exposure to household air pollution. We tested this assumption by measuring PM2.5 and levoglucosan concentrations inside homes and correlated them with wood stove age.

Wood smoke exposure affects lung aging, quality of life, and all-cause mortality in New Mexican smokers.

Background: The role of wood smoke (WS) exposure in the etiology of chronic obstructive pulmonary disease (COPD), lung cancer (LC), and mortality remains elusive in adults from countries with low ambient levels of combustion-emitted particulate matter. This study aims to delineate the impact of WS exposure on lung health and mortality in adults age 40 and older who ever smoked.

Methods: We assessed health impact of self-reported "ever WS exposure for over a year" in the Lovelace Smokers Cohort using both objective measures (i.

The Verran Professional Governance Scale: Confirmatory and Exploratory Analysis.

This article describes psychometric testing and refinement of the Verran Professional Governance Scale (VPGS), which measures behaviors associated with professional governance. Phase 1 reduced the items on the scale based on floor and ceiling effects and redundancy of items. Phase 2 examined structural construct validity using exploratory (EFA) and confirmatory factor analysis (CFA).

Racial and Ethnic Minorities Have a Lower Prevalence of Airflow Obstruction than Non-Hispanic Whites.

Racial and ethnic disparities in chronic obstructive pulmonary disease (COPD) are not well-studied. Our objective was to examine differences in limited COPD-related outcomes between three minority groups-African Americans (AAs), Hispanics, and American Indians (AIs) versus non-Hispanic Whites (NHWs), as the referent group, in separate cohorts. Separate cross-sectional evaluations were performed of three US-based cohorts of subjects at risk for COPD: COPDGene Study with 6,884 NHW and 3,416 AA smokers; Lovelace Smokers' Cohort with 1,598 NHW and 378 Hispanic smokers; and Mining Dust Exposure in the United States Cohort with 2,115 NHW, 2,682 Hispanic, and 2,467 AI miners.

Study Design: The study was a cross-sectional observational survey consisting of 95 items about personal and practice characteristics, respondents' practice environments, and professional burnout.

Stress and Coping Among Family Caregivers of Patients With a Destination Therapy Left Ventricular Assist Device: A Multicenter Mixed Methods Study.

Background: Family caregivers of patients with a destination therapy left ventricular assist device play a central and formalized role in postimplant care. We aimed to characterize longitudinal stress, predictors and correlates of stress, and coping processes among left ventricular assist device caregivers.

Methods: We performed a sequential, exploratory, mixed-methods study from 6 diverse left ventricular assist device programs.

Patient-centered Outcomes Research in Interstitial Lung Disease: An Official American Thoracic Society Research Statement.

In the past two decades, many advances have been made to our understanding of interstitial lung disease (ILD) and the way we approach its treatment. Despite this, many questions remain unanswered, particularly those related to how the disease and its therapies impact outcomes that are most important to patients. There is currently a lack of guidance on how to best define and incorporate these patient-centered outcomes in ILD research.

Automated location invariant animal detection in camera trap images using publicly available data sources.

A time-consuming challenge faced by camera trap practitioners is the extraction of meaningful data from images to inform ecological management. An increasingly popular solution is automated image classification software. However, most solutions are not sufficiently robust to be deployed on a large scale due to lack of location invariance when transferring models between sites.

Implementation and Outcomes of a Telehealth Neonatology Program in a Single Healthcare System.

Intermountain Healthcare, an early adopter and champion for newborn video-assisted resuscitation (VAR), identified a reduction in facility-level transfers and an estimated savings of $1. 2 million in potentially avoided transfers in a 2018 study. This study was conducted to increase understanding of VAR at the individual, newborn level.

Chronic disease self-care: A concept analysis.

The purpose of this concept analysis is to clarify and analyze the concept of self-care. Self-care is vital in the prevention, control, and management of chronic disease. It is substantially important in all aspects of health and all levels of care, and it is key to chronic disease management.

U-Infuse: Democratization of Customizable Deep Learning for Object Detection.

Image data is one of the primary sources of ecological data used in biodiversity conservation and management worldwide. However, classifying and interpreting large numbers of images is time and resource expensive, particularly in the context of camera trapping. Deep learning models have been used to achieve this task but are often not suited to specific applications due to their inability to generalise to new environments and inconsistent performance.

Inconsistency in Faculty and Student Perceptions of DNP and PhD Leader Scholarly Activity.

Objective: We aimed to quantify faculty and student perceptions of scholarly activities for doctor of nursing practice (DNP) and PhD leaders.

Background: The American Association of Colleges of Nursing describes DNP as a practice-focused degree and PhD as a research-focused degree. In 2016, the Council on Graduate Education for Administration in Nursing (now Association for Leadership Science in Nursing) published in the Journal of Nursing Administration sample practice objectives for DNP and research objectives for PhD leaders.

Home-Based Palliative Care: Perspectives of Chronic Obstructive Pulmonary Disease Patients and Their Caregivers.

Background: Home-based palliative care (HBPC) is an important aspect of care for patients with moderate to advanced stages of chronic obstructive pulmonary disease (COPD) and their caregivers. HBPC provides symptom management, advanced care planning and goals of care conversations in the home, with the goal of maximizing quality of life and minimizing health care utilization. There is a gap in the knowledge of how the patients with COPD and their caregivers experience HBPC.

Development and Initial Psychometric Testing of the Midwifery Practice Climate Scale.

Introduction: Perinatal care in the United States is plagued with a high maternal mortality rate and shortages of perinatal care providers. A supportive practice climate is a theoretically based and empirically demonstrated means of improving the quality of care and stabilizing the workforce; however, there has been limited research into the qualities and measurement of a supportive practice climate for midwives.

Methods: We developed a self-report instrument, the Midwifery Practice Climate Scale, to measure midwives' perceptions of the supportiveness of their work environments.
