International cross-sectional survey on current and updated definitions of intra-abdominal hypertension and abdominal compartment syndrome.

Background: The Abdominal Compartment Society (WSACS) established consensus definitions and recommendations for the management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in 2006, and they were last updated in 2013. The WSACS conducted an international survey between 2022 and 2023 to seek the agreement of healthcare practitioners (HCPs) worldwide on current and new candidate statements that may be used for future guidelines.

Methods: A self-administered, online cross-sectional survey was conducted under the auspices of the WSACS to assess the level of agreement among HCPs over current and new candidate statements.

The Utility and Limitations of Remotely Delivered Feedback Messages Regarding Physical Activity in a 12-Month Weight Loss Intervention: Insights From the SMARTER Trial Focus Groups.

Background: The increasing prevalence of obesity necessitates innovative interventions to address this grave public health concern. Standard behavioral therapy has been the mainstay for promoting weight loss, but its access and uptake are limited. The SMARTER randomized controlled trial aimed to explore the effects of self-monitoring with real-time, remotely delivered tailored feedback to recorded physical activity (PA) on weight loss.

Characterization of non-epithelial cells embedded within the vocal fold epithelial barrier.

The vocal folds vibrate to produce voice, undergoing significant stress due to contact and shearing force. The epithelium operates as the primary protective layer of the tissue against stress and vibratory damage, as well as to provide a barrier against foreign organisms and toxins. Within the vocal fold epithelium, non-epithelial cells were identified that may interrupt the epithelium and compromise the epithelial barrier's protective function.

Mechanotransduction in the Vocal Fold Microenvironment: A Narrative Review.

Purpose: The vocal fold tissues undergo nearly continuous and repeated cycles of injury and repair throughout the course of an individual's lifetime. It is well established that certain individuals are at greater risk of lesion development based on personality and behavioral classification. However, these characteristics alone do not wholly predict or explain lesion development or severity.

Shallow Subsidies for Veterans Facing Housing Barriers in the VA Supportive Services for Veteran Families Program.

The Department of Veterans Affairs provides a shallow subsidy (i.e., subsidizing 50% of an individual's rent for two years) to Veterans experiencing housing instability.

Comparison of the Biomechanics of the Mouse Astrocytic Lamina Cribrosa Between Glaucoma and Optic Nerve Crush Models.

Purpose: The strain response of the mouse astrocytic lamina (AL) to an ex vivo mechanical test was compared between two protocols: eyes that underwent sustained intraocular pressure (IOP) increase and eyes after optic nerve crush.

Methods: Chronic IOP elevation was induced by microbead injection or the optic nerve was crushed in mice with widespread green fluorescence. After 3 days or 6 weeks, eyes were inflation tested by a published method of two-photon fluorescence to image the AL.

Excellence in Antibiotic Stewardship: A Mixed-Methods Study Comparing High-, Medium-, and Low-Performing Hospitals.

Background: Despite antibiotic stewardship programs existing in most acute care hospitals, there continues to be variation in appropriate antibiotic use. While existing research examines individual prescriber behavior, contextual reasons for variation are poorly understood.

Methods: We conducted an explanatory, sequential mixed-methods study of a purposeful sample of 7 hospitals with varying discharge antibiotic overuse.

Challenges and Opportunities in the Elective Management of Diverticulitis: Perspectives From a National Sample of Colorectal Surgeons.

Background: Diverticulitis is a complex, heterogeneous disease process that affects a diverse population of patients. In the elective management of this disease, treatment guidelines have shifted toward patient-centered, individualized decision-making. It is not known what challenges surgeons face as they approach these nuanced treatment decisions in practice.

Regional Gene Expression in the Retina, Optic Nerve Head, and Optic Nerve of Mice with Optic Nerve Crush and Experimental Glaucoma.

A major risk factor for glaucomatous optic neuropathy is the level of intraocular pressure (IOP), which can lead to retinal ganglion cell axon injury and cell death. The optic nerve has a rostral unmyelinated portion at the optic nerve head followed by a caudal myelinated region. The unmyelinated region is differentially susceptible to IOP-induced damage in rodent models and human glaucoma.

Differences in perceptions and acceptance of COVID-19 vaccination between vaccine hesitant and non-hesitant persons.

Acceptance of the COVID-19 vaccination becomes more critical as new variants continue to evolve and the United States (US) attempts to move from pandemic response to management and control. COVID-19 stands out in the unique way it has polarized patients and generated sustained vaccine hesitancy over time. We sought to understand differences in perceptions and acceptance of COVID-19 vaccination between vaccine hesitant and non-hesitant patients, with the goal of informing communication and implementation strategies to increase uptake of COVID-19 vaccines in Veteran and non-Veteran communities.

Examining the Primary Care Experience of Patients With Opioid Use Disorder: A Qualitative Study.

Objectives: Despite substantial investment in expanding access to treatment for opioid use disorder (OUD), overdose deaths continue to increase. Primary care holds enormous potential to expand access to OUD treatment, but few patients receive medications for OUD (MOUD) in primary care. Understanding both patient and clinician experiences is critical to expanding access to patient-centered MOUD care, yet relatively little research has examined patient perspectives on primary care-based MOUD.

Acute Effects of Systemic Glucocorticoids on the Vocal Folds in a Pre-Clinical Model.

Objectives/hypothesis: Systemic glucocorticoids (GC)s are employed to treat various voice disorders. However, GCs have varying pharmacodynamic properties with adverse effects ranging from changes in epithelial integrity, skeletal muscle catabolism, and altered body weight. We sought to characterize the acute temporal effects of systemic dexamethasone and methylprednisolone on vocal fold (VF) epithelial glucocorticoid receptor (GR) nuclear translocation, epithelial tight junction (ZO-1) expression, thyroarytenoid (TA) muscle fiber morphology, and body weight using an established pre-clinical model.

A Qualitative Study of Emergency Physicians' and Nurses' Experiences Caring for Patients With Psychiatric Conditions and/or Substance Use Disorders.

Study Objective: Patients with psychiatric conditions and/or substance use disorders (SUDs) frequently seek care in emergency departments (EDs), where providing care for these populations can involve considerable challenges. This study aimed to develop a comprehensive data-driven model of the complex challenges and unique dynamics associated with caring for these populations in the ED, as well as the effect on patient care quality.

Methods: We conducted a preplanned topical analysis of grounded theory data obtained from semistructured interviews with 86 ED physicians and nurses from 8 hospitals in the Northeastern USA.

Pernicious Anemia and Vitamin B12 Deficiency Presenting As Pseudothrombotic Microangiopathy and Developing Secondary Thrombocytopenia After Treatment: A Case Report.

Pernicious anemia (PA) is an autoimmune disease secondary to chronic atrophic gastritis leading to vitamin B12 deficiency. Rarely, some patients may develop advanced hematological complications that mimic those of thrombotic thrombocytopenic purpura (TTP). Differentiating these conditions is crucial because they require different management.

Effects of experimental glaucoma in Lama1 mutant mice.

To identify changes in response to experimental intraocular pressure (IOP) elevation associated with the laminin α1 nmf223 mutation in mice. Laminin mutant (LM) mice (Lama1) and C57BL/6J (B6) mice in two age groups each (4-5 months and >1 year) underwent intracameral microbead injections to produce unilaterally elevated IOP. We assessed axonal transport block of immunofluorescently labeled amyloid precursor protein (APP) after 3 days and retinal ganglion cell (RGC) axon loss after 6 weeks.

Quantitative Microstructural Analysis of Cellular and Tissue Remodeling in Human Glaucoma Optic Nerve Head.

Purpose: To measure quantitatively changes in lamina cribrosa (LC) cell and connective tissue structure in human glaucoma eyes.

Methods: We studied 27 glaucoma and 19 age-matched non-glaucoma postmortem eyes. In 25 eyes, LC cross-sections were examined by confocal and multiphoton microscopy to quantify structures identified by anti-glial fibrillary acidic protein (GFAP), phalloidin-labeled F-actin, nuclear 4',6-diamidino-2-phenylindole (DAPI), and by second harmonic generation imaging of LC beams.

Identifying Perceptions, Experiences, and Recommendations of Telehealth Physical Therapy for Patients With Chronic Low Back Pain: A Mixed Methods Survey.

Objective: To describe concerns, advantages, and disadvantages encountered in an evidence-based physical therapy (PT) program for persons with chronic low back pain (CLBP) delivered by telehealth.

Design: Mixed methods survey and semistructured interview of persons with CLBP.

Aquaporin 4 is not present in normal porcine and human lamina cribrosa.

Aquaporin 4 is absent from astrocytes in the rodent optic nerve head, despite high expression in the retina and myelinated optic nerve. The purpose of this study was to quantify regional aquaporin channel expression in astrocytes of the porcine and human mouse optic nerve (ON). Ocular tissue sections were immunolabeled for aquaporins 1(AQP1), 4(AQP4), and 9(AQP9), myelin basic protein (MBP), glial fibrillary acidic protein (GFAP) and alpha-dystroglycan (αDG) for their presence in retina, lamina, myelin transition zone (MTZ, region just posterior to lamina) and myelinated ON (MON).

Intermittent complete heart block with ventricular standstill after Pfizer COVID-19 booster vaccination: A case report.

As the COVID-19 pandemic continues around the globe, vaccines are undoubtedly central to the fight to control the spread of the virus. However, as with any therapy, these vaccines are not without side effects. Documented cardiac complications of COVID-19 vaccination include myocarditis, pericarditis, and cardiac conduction abnormalities.

Urinary catheter monitoring of intra-abdominal pressure after major abdominal surgery, a cost-benefit analysis.

Objective: To estimate costs and benefits associated with measurement of intra-abdominal pressure (IAP).

Methods: We built a cost-benefit analysis from the hospital facility perspective and time horizon limited to hospitalization for patients undergoing major abdominal surgery for the intervention of urinary catheter monitoring of IAP. We used real-world data estimating the likelihood of intra-abdominal hypertension (IAH), abdominal compartment syndrome (ACS), and acute kidney injury (AKI) requiring renal replacement therapy (RRT).

Mechanical strain in the mouse astrocytic lamina increases after exposure to recombinant trypsin.

The responses of astrocytes in the optic nerve head (ONH) to mechanical and biochemical stimuli are important to understanding the degeneration of retinal ganglion cell axons in glaucoma. The ONH in glaucoma is vulnerable to stress produced by the intraocular pressure (IOP). Notably, after three days of elevated IOP in a mouse model, the junctions between the astrocytic processes and the peripapillary sclera were altered and the structural compliance of the ONH increased.
