Outpatient parenteral antimicrobial therapy (OPAT) for the management of periprosthetic joint infections in the Republic of Ireland (ROI) from 2013 to 2021.

Objectives: Periprosthetic joint infection (PJI) is a complication of joint arthroplasty and is seen in 1-2% of cases. Since its initiation in 2013, the national outpatient parenteral antimicrobial therapy (OPAT) program has facilitated the outpatient management of intravenous antimicrobials for PJI. This study aims to describe the clinical epidemiology of patients on OPAT with PJI between 2013 and 2021.

Outpatient parenteral antimicrobial therapy (OPAT) across the world: a comparative analysis-what lessons can we learn?

This paper presents a comparative analysis of Outpatient Parenteral Antimicrobial Therapy (OPAT) structures and delivery options across different countries. OPAT, a cost-effective alternative to inpatient care for patients requiring IV antimicrobial therapy, has demonstrated multiple benefits such as patient satisfaction, economic cost savings, and reduced hospital-acquired infections. Despite these advantages, there is considerable international variation in OPAT use and implementation.

Short term e-bicycle riding results in favorable cardiometabolic shifts in moderately active adults.

Purpose: Electric bikes (EB) are a form of active transportation with demonstrated health benefits. The purpose of this study was to determine the influence of riding an EB for one week on indices of cardiometabolic health in middle-aged adults.

Methods: Adults (n = 22; age = 57.

A comparison of energy expenditure and perceived exertion between standard axillary crutches, knee scooters, and a hands-free crutch.

Background: Ambulation using standard axillary crutches (SACs) is associated with increased energy expenditure (EE) and decreased ability to perform activities of daily living (ADLs). Using a hands-free crutch (HFC) displays potential for easier completion of ADLs and reduction in energy requirements.

Objectives: To determine if a HFC elicits lower EE and heart rate (HR), improvement in performance of ADLs, and decreased rating of perceived exertion (RPE) compared to common ambulatory devices.

Disuse-induced muscle fibrosis, cellular senescence, and senescence-associated secretory phenotype in older adults are alleviated during re-ambulation with metformin pre-treatment.

Muscle inflammation and fibrosis underlie disuse-related complications and may contribute to impaired muscle recovery in aging. Cellular senescence is an emerging link between inflammation, extracellular matrix (ECM) remodeling and poor muscle recovery after disuse. In rodents, metformin has been shown to prevent cellular senescence/senescent associated secretory phenotype (SASP), inflammation, and fibrosis making it a potentially practical therapeutic solution.

Mechanisms of mechanical overload-induced skeletal muscle hypertrophy: current understanding and future directions.

Mechanisms underlying mechanical overload-induced skeletal muscle hypertrophy have been extensively researched since the landmark report by Morpurgo (1897) of "work-induced hypertrophy" in dogs that were treadmill trained. Much of the preclinical rodent and human resistance training research to date supports that involved mechanisms include enhanced mammalian/mechanistic target of rapamycin complex 1 (mTORC1) signaling, an expansion in translational capacity through ribosome biogenesis, increased satellite cell abundance and myonuclear accretion, and postexercise elevations in muscle protein synthesis rates. However, several lines of past and emerging evidence suggest that additional mechanisms that feed into or are independent of these processes are also involved.

Global deletion of CCL2 has adverse impacts on recovery of skeletal muscle fiber size and function and is muscle specific.

Timely and complete recovery of muscle mass and function following a bout of physical disuse are critical components of returning to normal activities of daily living and lifestyle. Proper cross talk between the muscle tissue and myeloid cells (e.g.

Skin Assessment in Patients with Dark Skin Tone.

There is a scarcity of nursing literature, studies, and educational materials on the assessment and early recognition of both common and serious integumentary and general health issues in people with dark skin tones. Nurses must be exposed to such learning resources to be adequately prepared to care for patients with diverse skin tones and to help reduce health disparities and promote health equity. This article provides faculty, nursing students, and clinicians with basic information about the assessment of dark skin tone and calls for action in academia and professional practice to ensure nurses and nursing students can effectively perform skin assessments in all patients.

Muscle disuse as hindlimb unloading in early postnatal mice negatively impacts grip strength in adult mice: a pilot study.

Physical inactivity has many detrimental effects on health, yet the impact of physical inactivity in early life on muscle health in adulthood remains unknown. Early postnatal malnutrition has prolonged effects into adulthood and we propose that early postnatal (P) physical inactivity would have similar negative effects. To test this hypothesis, we exposed postnatal mice (∼, C57BL/6J) to 14 days of physical inactivity (shortly after weaning, from ∼P28 to P42 days of age) in the form of muscle disuse with hindlimb unloading (HU).

Justice, Equity, and Inclusion in a School of Nursing: A Quality Improvement Program.

Background: Despite the increased racial and ethnic diversity in the general population of the United States, the nursing workforce remains mostly White. Schools of nursing (SON) have increased recruitment and enrollment; however, students who represent racial and ethnic minoritized groups experience microaggressions, injustice, and social exclusion. This quality improvement program sought to equip faculty with skills to create a just and inclusive SON.

Macrophage immunomodulation accelerates skeletal muscle functional recovery in aged mice following disuse atrophy.

Poor recovery of muscle size and strength with aging coincides with a dysregulated macrophage response during the early stages of regrowth. Immunomodulation in the form of ex vivo cytokine (macrophage-colony stimulating factor) or polarized macrophage delivery has been demonstrated to improve skeletal muscle regeneration. However, it is unclear if these macrophage-promoting approaches would be effective to improve skeletal muscle recovery following disuse in aged animals.

Leading as Servant in Times of Crisis.

Using servant leadership as a framework, leaders within a school of nursing guided faculty during the COVID-19 pandemic and called them to address social injustice in the summer of 2020. A model was developed to sustain growth and build resilience of students, faculty, and staff. Influenced by external and internal drivers that stimulated the need for change, strategies were implemented based on core principles of servant leadership.

Isavuconazole Treatment of Spinal Cord Invasive Aspergillosis Guided by Cerebrospinal Fluid (1,3)-β-d-Glucan Levels in a Patient with Low Interferon-Gamma and Ulcerative Colitis.

This case highlights the use of (1,3)-beta-d glucan to direct treatment of a cervical spinal cord Aspergillus fumigatus infection in a 22-year-old woman immunocompromised due to steroid and anti-TNF therapy in the context of ulcerative colitis and interferon gamma deficiency. A 4-year treatment course requiring neurosurgical intervention on four occasions and prolonged antifungal therapy, including isavuconazole, resulted in clinical cure with a corresponding decrease in CSF beta-d-glucan to <30 pg/mL. Serum and CSF galactomannan levels were not elevated at any point during the clinical course.

Metformin and leucine increase satellite cells and collagen remodeling during disuse and recovery in aged muscle.

Loss of muscle mass and strength after disuse followed by impaired muscle recovery commonly occurs with aging. Metformin (MET) and leucine (LEU) individually have shown positive effects in skeletal muscle during atrophy conditions but have not been evaluated in combination nor tested as a remedy to enhance muscle recovery following disuse atrophy in aging. The purpose of this study was to determine if a dual treatment of metformin and leucine (MET + LEU) would prevent disuse-induced atrophy and/or promote muscle recovery in aged mice and if these muscle responses correspond to changes in satellite cells and collagen remodeling.

Parents' Intentions to Vaccinate Their Children Against COVID-19.

Introduction: With the COVID-19 vaccine rollout is well underway now beginning in children ages 12 and over, it is unknown what percent of parents plan to vaccinate their children against COVID-19.

Method: The purpose of this descriptive correlational study was to examine parents' attitudes, beliefs, and behaviors in administering a COVID-19 vaccine.

Results: Only 21.

Effect of the lysosomotropic agent chloroquine on mTORC1 activation and protein synthesis in human skeletal muscle.

Background: Previous work in HEK-293 cells demonstrated the importance of amino acid-induced mTORC1 translocation to the lysosomal surface for stimulating mTORC1 kinase activity and protein synthesis. This study tested the conservation of this amino acid sensing mechanism in human skeletal muscle by treating subjects with chloroquine-a lysosomotropic agent that induces in vitro and in vivo lysosome dysfunction.

Methods: mTORC1 signaling and muscle protein synthesis (MPS) were determined in vivo in a randomized controlled trial of 14 subjects (10 M, 4 F; 26 ± 4 year) that ingested 10 g of essential amino acids (EAA) after receiving 750 mg of chloroquine (CHQ, n = 7) or serving as controls (CON, n = 7; no chloroquine).

A pragmatic methodology for the evaluation of digital care management in the context of multimorbidity.

Multimorbidity is a defining challenge for health systems and requires coordination of care delivery and care management. Care management is a clinical service designed to remotely engage patients between visits and after discharge in order to support self-management of chronic and emergent conditions, encourage increased use of scheduled care and address the use of unscheduled care. Care management can be provided using digital technology - digital care management.

Short-term metformin ingestion by healthy older adults improves myoblast function.

Muscle progenitor cells (MPCs) in aged muscle exhibit impaired activation into proliferating myoblasts, thereby impairing fusion and changes in secreted factors. The antihyperglycemic drug metformin, currently studied as a candidate antiaging therapy, may have potential to promote function of aged MPCs. We evaluated the impact of 2 wk of metformin ingestion on primary myoblast function measured in vitro after being extracted from muscle biopsies of older adult participants.

Preclinical rodent models of physical inactivity-induced muscle insulin resistance: challenges and solutions.

Physical inactivity influences the development of muscle insulin resistance yet is far less understood than diet-induced muscle insulin resistance. Progress in understanding the mechanisms of physical inactivity-induced insulin resistance is limited by a lack of an appropriate preclinical model of muscle insulin resistance. Here, we discuss differences between diet and physical inactivity-induced insulin resistance, the advantages and disadvantages of the available rodent inactivity models to study insulin resistance, and our current understanding of the mechanisms of muscle insulin resistance derived from such preclinical inactivity designs.

Unintended consequences of long-sleeved gowns in a critical care setting during the COVID-19 pandemic.

At the peak of the coronavirus disease 2019 (COVID-19) pandemic, hand hygiene audits indicated decreased compliance in a 12-bed critical care (CC) area with ventilated COVID-19 patients, where staff used personal protective equipment (PPE), including sessional use of long-sleeved gowns in accordance with the recommendations of Public Health England. There was also a cluster of three central venous catheter (CVC) infections along with increases in the number of patients from whom enteric Gram-negative bacteria (GNB) were isolated from sterile sites. Environmental sampling of near-patient surfaces and frequently touched sites demonstrated that 11.

Neuromuscular electrical stimulation and protein during bed rest increases CD11b skeletal muscle macrophages but does not correspond to muscle size or insulin sensitivity.

With this cohort, we previously demonstrated preservation of thigh lean tissue with neuromuscular electrical stimulation combined with protein supplementation (NMES+PRO) treatment during bed rest in healthy older adults. Because macrophage polarization plays a significant role in the repair and maintenance of muscle size and insulin sensitivity, we hypothesized that muscle macrophages would be induced by NMES+PRO and would correspond to an increase in lean mass and an attenuated insulin resistance response altered by bed rest. Older adults (60-80 years old; body mass index < 30 kg/m) underwent 5 days of bed rest and were randomized to either thrice daily treatment of NMES+PRO ( = 8) or CON ( = 8).
