Prospective Associations of Accelerometer-Measured Machine-Learned Sedentary Behavior With Death Among Older Women: The OPACH Study.

Background: Sedentary behavior is a recognized mortality risk factor. The novel and validated convolutional neural network hip accelerometer posture algorithm highly accurately classifies sitting and postural changes compared with accelerometer count cut points. We examined the prospective associations of convolutional neural network hip accelerometer posture-classified total sitting time and mean sitting bout duration with all-cause and cardiovascular disease (CVD) death.

Branching phenomena in nanostructure synthesis illuminated by the study of Ni-based nanocomposites.

Branching phenomena are ubiquitous in both natural and artificial crystallization processes. The branched nanostructures' emergent properties depend upon their structures, but their structural tunability is limited by an inadequate understanding of their formation mechanisms. Here we developed an ensemble of Nickel-Based nano-Composites (NBCs) to investigate branching phenomena in solution-phase synthesis with precision and in depth.

Sedentary Behavior and Atrial Fibrillation in Older Women: The OPACH Study.

Background Sedentary behavior is associated with cardiovascular disease, but its association with incident atrial fibrillation is not well studied. Our aim was to measure the association between objectively measured sedentary behavior and incident atrial fibrillation. Methods and Results Sedentary behavior was measured by a triaxial accelerometer worn on a belt for 1 week.

Oral Microbiome Is Associated With Incident Hypertension Among Postmenopausal Women.

Background Oral microbiota are thought to influence blood pressure (BP) regulation. However, epidemiological data supporting this hypothesis are limited. We examined associations between oral microbiota, BP, and incident hypertension in postmenopausal women.

Accelerometer-Derived Daily Life Movement Classified by Machine Learning and Incidence of Cardiovascular Disease in Older Women: The OPACH Study.

Background Current physical activity guidelines focus on volume and intensity for CVD prevention rather than common behaviors responsible for movement, including those for daily living activities. We examined the associations of a machine-learned, accelerometer-measured behavior termed daily life movement (DLM) with incident CVD. Methods and Results Older women (n=5416; mean age, 79±7 years; 33% Black, 17% Hispanic) in the Women's Health Initiative OPACH (Objective Physical Activity and Cardiovascular Health) study without prior CVD wore ActiGraph GT3X+ accelerometers for up to 7 days from May 2012 to April 2014 and were followed for physician-adjudicated incident CVD through February 28th, 2020 (n=616 events).

Patient Deterioration on General Care Units: A Concept Analysis.

Patient deterioration is a phenomenon that occurs from the inability to recognize it or respond to a change in condition. Despite the published reports on recognizing a deteriorating patient on general care floors, a gap remains in the ability of nurses to describe the concept, affecting patient outcomes. Walker and Avant's approach was applied to analyze patient deterioration.

Healthy Lifestyle and Clonal Hematopoiesis of Indeterminate Potential: Results From the Women's Health Initiative.

Background Presence of clonal hematopoiesis of indeterminate potential (CHIP) is associated with a higher risk of atherosclerotic cardiovascular disease, cancer, and mortality. The relationship between a healthy lifestyle and CHIP is unknown. Methods and Results This analysis included 8709 postmenopausal women (mean age, 66.

Copper@ZIF-8 Core-Shell Nanowires for Reusable Antimicrobial Face Masks.

SARS-CoV-2 and other respiratory viruses spread via aerosols generated by infected people. Face masks can limit transmission. However, widespread use of disposable masks consumes tremendous resources and generates waste.

Short Physical Performance Battery and Incident Cardiovascular Events Among Older Women.

Background The Short Physical Performance Battery (SPPB) is an inexpensive, reliable, and easy-to-implement measure of lower-extremity physical function. Strong evidence links SPPB scores with all-cause mortality, but little is known about its relationship with incident cardiovascular disease (CVD). Methods and Results Women (n=5043, mean age=79±7) with no history of myocardial infarction or stroke completed 3 timed assessments-standing balance, strength (5 chair stands), and usual gait speed (4 m walk)-yielding an SPPB score from 0 (worst) to 12 (best).

Opioid-Induced Sedation and Respiratory Depression: Are Sedation Scales Enough to Prevent Adverse Drug Events Postoperatively?

Objectives: Nurses who care for hospitalized patients are responsible for ensuring adequate pain management is provided in a safe manner. The clinical challenge is balancing the effective control of the patient's pain with the side effects of administering opioids. The aim of this literature review is to explore the evidence on how nurses assess for opioid-induced sedation and advancing respiratory depression and how they integrate those data in their critical thinking skills when deciding to administer opioids for pain.

The common meanings and shared practices of sedation assessment in the context of managing patients with an opioid: A phenomenological study.

Aims And Objectives: To examine the common meanings of opioid-induced sedation and shared practices in the context of post-operative pain management in expert Post-Anesthesia Care Unit nurses during patient's pain management with opioids.

Background: Within the clinical setting, linear pain and sedation scales are not enough to support clinical judgement with acute pain management. Because sedation measurement rests along a fluctuating continuum, it is possible for a patient to be sedated and then shift to increasing alertness, and then to drift back to a sedated state.

Sedation scales: Do they capture the concept of opioid-induced sedation?

Aim: The purpose of this study was to explore the concept of opioid-induced sedation and how nurses define and measure sedation in the hospital setting.

Background: Opioid medications are the primary treatment for acute pain in the postoperative setting. One of the most serious side effects of opioid therapy is excessive sedation and respiratory depression.

Questionnaires that screen for multiple sleep disorders.

The goal of this review was to identify, describe, and evaluate the existing multiple sleep disorders screening questionnaires for their comprehensiveness, brevity, and psychometric quality. A systematic review was conducted using Medline/PubMed, cumulative index to nursing & allied health literature, health and psychosocial instruments and the "grey literature". Search terms were "sleep disorders, screening, questionnaires, and psychometrics".

Antibiotics in acute exacerbations of chronic bronchitis.

Acute exacerbations of chronic bronchitis (AECB) are a major contributor to morbidity and mortality in patients with chronic obstructive pulmonary disease, accounting for more than 16 million physician office visits and over 500,000 hospitalizations in the USA each year. Antimicrobials have been recognized by clinical guidelines as an important component in the management of AECB with a bacterial etiology. The challenge of identifying patients most likely to benefit from antimicrobial therapy is difficult in the clinical setting.
