"What Does 'Age-Friendly' Mean to You?": The Role of Microaggressions in a Retirement and Assisted Living Community.

Background And Objectives: In conversations about expanding age-friendly ecosystems, the concept of "age-friendliness" has not been explored in relation to residential settings.

Research Design And Methods: This multiple-case study compared four residents' perspectives on the age-friendliness of a retirement and assisted living community, combining individual semi-structured interviews with observational data and organizational document analyses in a contextualist thematic examination.

Results: Three themes depict (A) existing experiences of the setting as "age-friendly" and the tension of the built design vs.

Impact of Antecedent and Organizational Differences on Nurse-Social Worker Collaboration in a Retirement and Assisted Living Community with Skilled Nursing Care.

Nurse-social worker collaborative interactions in long-term care settings have received limited attention. This qualitative thematic study of 23 participants (11 social workers and 12 nurses) at an urban retirement and assisted living community explores experiences of collaborative work. Two themes of contrasts in responding to resident complexity and contrasts in peer-to-peer work highlight four subthemes reflecting: (a) social workers' orientation toward resident self-determination, requisite care, and advocacy; (b) nurses' orientation toward resident safety, tasks, and clinical outcomes; (c) social workers' devalued professional identity; and (d) nurses' attribution of collaborative challenges to individuals.

Miracle friends and miracle money in California: a mixed-methods experiment of social support and guaranteed income for people experiencing homelessness.

Background: This paper describes the protocols for a randomized controlled trial using a parallel-group trial design that includes an intervention designed to address social isolation and loneliness among people experiencing homelessness known as Miracle Friends and an intervention that combines Miracles Friends with an economic poverty-reduction intervention known as Miracle Money. Miracle Friends pairs an unhoused person with a volunteer "phone buddy." Miracle Money provides guaranteed basic income of $750 per month for 1 year to Miracle Friends participants.

Association of Total Hip Arthroplasty Flexural Rigidity With Magnetic Resonance Imaging and Histological Findings.

Background: Modular connections in total hip arthroplasty (THA) offer surgical advantages, but can contribute to implant fretting and corrosion due to micromotion at the head-stem interface. Previous studies implicated lower flexural rigidity as a key contributing factor to THA corrosion and fretting, but none associated flexural rigidity with direct histological evaluation or magnetic resonance imaging (MRI) outcomes. The purpose of this study was to determine how implant flexural rigidity is associated with MRI imaging metrics and histopathological outcomes in patients who have a failed THA.

Clinical outcomes and return to dance after total hip arthroplasty or hip resurfacing in professional dancers.

Aims: Professional dancers represent a unique patient population in the setting of hip arthroplasty, given the high degree of hip strength and mobility required by their profession. We sought to determine the clinical outcomes and ability to return to professional dance after total hip arthroplasty (THA) or hip resurfacing arthroplasty (HRA).

Methods: Active professional dancers who underwent primary THA or HRA at a single institution with minimum one-year follow-up were included in the study.

From the streets to a hotel: a qualitative study of the experiences of homeless persons in the pandemic era.

In the wake of COVID-19, programs for housing homeless individuals in hotels have emerged in the U.S., though research has yielded little information about the impact of these programs on participants expressed in their own words.

What Is the Role of a Periarticular Injection for Knee Arthroplasty Patients Receiving a Multimodal Analgesia Regimen Incorporating Adductor Canal and Infiltration Between the Popliteal Artery and Capsule of the Knee Blocks? A Randomized Blinded Placebo-Controlled Noninferiority Trial.

Background: Optimal analgesic protocols for total knee arthroplasty (TKA) patients remain controversial. Multimodal analgesia is advocated, often including peripheral nerve blocks and/or periarticular injections (PAIs). If 2 blocks (adductor canal block [ACB] plus infiltration between the popliteal artery and capsule of the knee [IPACK]) are used, also performing PAI may not be necessary.

Golfing after Orthopaedic Surgery: A longitudinal follow-up (GOLF) study protocol.

Aims: The primary aim of this prospective, multicentre study is to describe the rates of returning to golf following hip, knee, ankle, and shoulder arthroplasty in an active golfing population. Secondary aims will include determining the timing of return to golf, changes in ability, handicap, and mobility, and assessing joint-specific and health-related outcomes following surgery.

Methods: This is a multicentre, prospective, longitudinal study between the Hospital for Special Surgery, (New York City, New York, USA) and Edinburgh Orthopaedics, Royal Infirmary of Edinburgh, (Edinburgh, UK).

"It's Stable but Not Stable": A Conceptual Framework of Subjective Housing Stability Definition Among Individuals with Co-occurring Mental Health and Substance Use Disorders.

Despite increasing efforts to improve housing stability, research has largely defined housing stability in a narrow sense and heavily relied on objective measures, such as housing types and housing duration. The present study constructed a conceptual framework for a subjective housing stability definition from the perspectives of individuals with co-occurring mental health and substance use disorders and their behavioral health service providers. Following the principles of grounded theory, we collected and analyzed qualitative data through semistructured interviews with 24 individuals with serious mental illness and substance use problems and three focus groups with 22 behavioral health service providers.

Machine Learning on Medicare Claims Poorly Predicts the Individual Risk of 30-Day Unplanned Readmission After Total Joint Arthroplasty, Yet Uncovers Interesting Population-level Associations With Annual Procedure Volumes.

Background: Unplanned hospital readmissions after total joint arthroplasty (TJA) represent potentially serious adverse events and remain a critical measure of hospital quality. Predicting the risk of readmission after TJA may provide patients and clinicians with valuable information for preoperative decision-making.

Questions/purposes: (1) Can nonlinear machine-learning models integrating preoperatively available patient, surgeon, hospital, and county-level information predict 30-day unplanned hospital readmissions in a large cohort of nationwide Medicare beneficiaries undergoing TJA? (2) Which predictors are the most important in predicting 30-day unplanned hospital readmissions? (3) What specific information regarding population-level associations can we obtain from interpreting partial dependency plots (plots describing, given our modeling choice, the potentially nonlinear shape of associations between predictors and readmissions) of the most important predictors of 30-day readmission?

Methods: National Medicare claims data (chosen because this database represents a large proportion of patients undergoing TJA annually) were analyzed for patients undergoing inpatient TJA between October 2016 and September 2018.

Evaluation of Mechanically-Assisted Crevice Corrosion of Different Modular Dual Mobility Constructs.

Background: Modular dual mobility (MDM) acetabular component use is rising in total hip arthroplasty. However, concern of mechanically assisted crevice corrosion (MACC) at the shell-liner interface remains. We investigated shell-liner corrosion using retrieval analyses and corrosion chamber testing.

Silky dogwood (Swida amomum) seed dispersal by freshwater turtles.

Premise: Effective seed dispersal is essential to the success of plant species. Swida amomum (silky dogwood) has a seed-dispersal syndrome characteristic of autumn-ripening shrubs with fleshy fruits; attached fruits are ingested and defecated by birds, while fallen fruits are consumed by ground-foraging birds and mammals.

Methods: We documented that fallen fruits of this shrub were consumed by two aquatic turtle species (eastern painted turtle [Chrysemys picta] and red-eared slider [Trachemys scripta]) and that their seeds were defecated.

Late-onset opportunistic infections while receiving anti-retroviral therapy in Latin America: burden and risk factors.

Objectives: The aim of this study was to describe the incidence, clinical characteristics, and risk factors of late-onset opportunistic infections (LOI) in people who live with HIV (PWLHA) within the Caribbean, Central and South America network for HIV epidemiology.

Methods: We performed a retrospective cohort study including treatment-naive PWLHA enrolled at seven sites (Argentina, Brazil, Chile, Peru, Mexico, and two sites in Honduras). Follow-up began at 6 months after treatment started.

Behavioral Crisis and First Response: Qualitative Interviews with Chicago Stakeholders.

Improving interactions between first responders and individuals experiencing behavioral crisis is a critical public health challenge. To gain insight into these interactions, key informant qualitative interviews were conducted with 25 Chicago stakeholders. Stakeholders included directors and staff of community organizations and shelters that frequently engage first responders.

Weight gain post-ART in HIV+ Latinos/as differs in the USA, Haiti, and Latin America.

Background: An obesity epidemic has been documented among adult Latinos/as in Latin America and the United States (US); however, little is known about obesity among Latinos/as with HIV (PWH). Moreover, Latinos/as PWH in the US may have different weight trajectories than those in Latin America due to the cultural and environmental contexts. We assessed weight and body mass index (BMI) trajectories among PWH initiating antiretroviral therapy (ART) across 5 countries in Latin America and the Caribbean and the US.

Tuberculosis treatment intermittency in the continuation phase and mortality in HIV-positive persons receiving antiretroviral therapy.

Background: Some tuberculosis (TB) treatment guidelines recommend daily TB treatment in both the intensive and continuation phases of treatment in HIV-positive persons to decrease the risk of relapse and acquired drug resistance. However, guidelines vary across countries, and treatment is given 7, 5, 3, or 2 days/week. The effect of TB treatment intermittency in the continuation phase on mortality in HIV-positive persons on antiretroviral therapy (ART), is not well-described.

Transitioning to independent living: Experiences of homeless young adults in rapid rehousing.

Rapid rehousing (RRH) is an intervention that is being adopted nationally to assist adolescents and emerging adults who are homeless. RRH provides short-term rental assistance for independent scattered-site housing, in addition to an array of support services for approximately 12-24 months. The aim of this study is to explore the experiences of young adults (18-23 years old) who had previously been homeless and who were enrolled in RRH programs set in two urban Northeastern cities, and their subsequent preparedness for independent living.

A Postmortem Analysis of Polyethylene Damage and Periprosthetic Tissue in Rotating Platform and Fixed Bearing Tibial Inserts.

Background: Mobile bearing designs are intended to reduce wear, but mixed results were reported from retrieval analyses. Postmortem evaluation (PM) provides the opportunity to assess polyethylene damage in successful implants. We compared damage patterns, MRI presentation, and histology between mobile-bearing and fixed tibial inserts retrieved postmortem and compared these results to our prior findings from implants retrieved at revision.

Relative pressure estimation from 4D flow MRI using generalized Bernoulli equation in a phantom model of arterial stenosis.

Objective: Arterial stenosis is a significant cardiovascular disease requiring accurate estimation of the pressure gradients for determining hemodynamic significance. In this paper, we propose Generalized Bernoulli Equation (GBE) utilizing interpolated-based method to estimate relative pressures using streamlines and pathlines from 4D Flow MRI.

Methods: 4D Flow MRI data in a stenotic phantom model and computational fluid dynamics simulated velocities generated under identical flow conditions were processed by Generalized Bernoulli Equation (GBE), Reduced Bernoulli Equations (RBE), as well as the Simple Bernoulli Equation (SBE) which is clinically prevalent.

Patient views on emergency department screening and interventions related to housing.

Objectives Emergency departments (EDs) serve as a health care "safety net" and may be uniquely suited to screening for and addressing patients' unmet social needs. We aimed to better understand patient perspectives on ED-based screening and interventions related to housing instability, as a step toward improving future efforts. Methods We present findings from a qualitative study using in-depth, one-on-one interviews with ED patients who had become homeless in the past 6 months.

Development and Validation of Crosswalks Between the Western Ontario & McMaster Universities Osteoarthritis Index and Hip Disability and Osteoarthritis Outcome Score Joint Replacement/Knee Injury and Osteoarthritis Outcome Score Joint Replacement.

Background: The wide variety of patient-reported outcome measures used to assess outcomes following total joint arthroplasty can present a substantial methodological obstacle when attempting to compare information across studies or between institutions. A simple solution is to create crosswalks that reliably convert scores between patient-reported outcome measures. Our goal is to create and validate crosswalks between the commonly used Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) and short-form versions of the Hip Disability and Osteoarthritis Outcome Score Joint Replacement (HOOS JR)/Knee Injury and Osteoarthritis Outcome Score (KOOS JR.
