Removal of primary total knee arthroplasty (TKA) and primary total hip arthroplasty (THA) from the inpatient-only list has financial implications for both patients and institutions. The aim of this study was to evaluate and compare financial parameters between patients designated for inpatient versus outpatient total joint arthroplasty.
We reviewed all patients who underwent TKA or THA after these procedures were removed from the inpatient-only list. Patients were statistical significance into cohorts based on inpatient or outpatient status, procedure type, and insurance type. This included 5,284 patients, of which 4,279 were designated inpatient while 1,005 were designated outpatient. Patient demographic, perioperative, and financial data including per patient revenues, total and direct costs, and contribution margins (CMs) were collected. Data were compared using t-tests and Chi-squared tests.
Among Medicare patients receiving THA, CM was 89.1% lower for the inpatient cohort when compared to outpatient (P < .001), although there was no statistical significance difference between cohorts for TKA (P= .501). Among patients covered by Medicaid or Government-managed plans, CM was 120.8% higher for inpatients receiving THA (P < .001) when compared to outpatients and 136.3% higher for inpatients receiving TKA (P < .001).
Our analyses showed that recent costs associated with inpatient stay inconsistently match or outpace additional revenue, causing CM to vary drastically depending on insurance and procedure type. For Medicare patients receiving THA, inpatient surgery is financially disincentivized leaving this vulnerable patient population at a risk of losing access to care.

There is limited evidence exploring the relationship between mental health disorders and the readmissions following total joint arthroplasty (TJA). Therefore, we conducted a meta-analysis to evaluate the relationship between mental health disorders and the risk of readmission following TJA.
We searched PubMed, Cochrane, and Google Scholar from their inception till April 19, 2022. Studies exploring the association of mental health disorders and readmission risk following TJA were selected. The outcomes were divided into 30-day readmission, 90-day readmission, and readmission after 90 days. We also performed subgroup analyses based on the type of arthroplasty total hip arthroplasty (THA) and total knee arthroplasty (TKA). A total of 12 studies were selected, of which 11 were included in quantitative analysis. A total of 1,345,893 patients were evaluated, of which 73,953 patients suffered from mental health disorders.
The risk of 30-day readmission (odds ratio= 1.43, 95% CI 1.14-1.80, P= .002, I
= 87%) aner postoperative management in these patients.
Obesity is associated with component malpositioning and increased revision risk after total hip arthroplasty (THA). With anterior approaches (AAs) becoming increasingly popular, the goal of this study was to assess whether clinical outcome post-AA-THA is affected by body mass index (BMI).
This multicenter, multisurgeon, consecutive case series used a prospective database of 1,784 AA-THAs (1,597 patients) through bikini (n= 1,172) or standard (n= 612) incisions. Mean age was 63 years (range, 20-94 years) and there were 57.5% women, who had a mean follow-up of 2.7 years (range, 2.0-4.1 years). Patients were classified into the following BMI groups normal (BMI < 25.0; n= 572); overweight (BMI 25.0-29.9; n= 739); obese (BMI 30.0-34.9; n= 330); and severely obese (BMI ≥ 35.0; n= 143). Outcomes evaluated included hip reconstruction (inclination/anteversion and leg-length, complications, and revision rates) and patient-reported outcomes including Oxford Hip Scores (OHS).
Mean postoperative leg-length differvements among BMI groups. Obese patients have a higher risk of PJIs. Bikini incision for AA-THA can help minimize the risk of wound complications.
AA-THA is a credible option for obese patients, with low dislocation or fracture risk and excellent ability to reconstruct the hip, leading to comparable functional improvements among BMI groups. Obese patients have a higher risk of PJIs. Bikini incision for AA-THA can help minimize the risk of wound complications.Alzheimer's disease (AD) is a progressive neurodegenerative disorder for which only symptomatic medication is available, except for the recently FDA-approved aducanumab. This lack of effective treatment urges us to investigate alternative paths that might contribute to disease development. In light of the recent SARS-CoV-2 pandemic and the disturbing neurological complications seen in some patients, it is desirable to (re)investigate the viability of the viral infection theory claiming that a microbe could affect AD initiation and/or progression. Here, we review the most important evidence for this theory with a special focus on two viruses, namely HSV-1 and SARS-CoV-2. Moreover, we discuss the possible involvement of extracellular vesicles (EVs). This overview will contribute to a more rational approach of potential treatment strategies for AD patients.
Often people with lymphedema and vascular conditions will be prescribed layered compression garments to assist them in donning their garments and improve treatment compliance. However, little evidence of the interface pressures produced by these layered garments is available. In the present study, we explored the pressures produced by layering high and low class below-the-knee compression garment combinations and quantified the graduation of these combinations to understand the effect that layer order might have on the interface pressure.
The present study used a mechanical test design to measure the interface pressure at four sites (B, smallest ankle dimension; B1, circumference at Achilles tendon and gastrocnemius muscle junction; C, widest calf dimension; and D, below the knee) for 30 combinations of low and high class compression garments using a PicoPress (Microlab Elettronica, Ponte San Nicolò, Italy).
The results demonstrated a pattern consistent with graduation for sites B1 to D for 100% of the inically, garment wearers can don their layered garments in any order and achieve the same interface pressure results.
Graduation was observed from site B1 to site D, indicating that double layering of these garment combinations maintained guideline adherence. Layering the garments produced pressures that were, in general, cumulative of the pressure from each garment alone, with some variance. Because of the uncertainty of the B site results in the present study, the clinical implications in relation to the primary aim are limited. The findings from the secondary aim suggest that clinically, garment wearers can don their layered garments in any order and achieve the same interface pressure results.There is significant interest in pooling magnetic resonance image (MRI) data from multiple datasets to enable mega-analysis. Harmonization is typically performed to reduce heterogeneity when pooling MRI data across datasets. Most MRI harmonization algorithms do not explicitly consider downstream application performance during harmonization. However, the choice of downstream application might influence what might be considered as study-specific confounds. Therefore, ignoring downstream applications during harmonization might potentially limit downstream performance. Here we propose a goal-specific harmonization framework that utilizes downstream application performance to regularize the harmonization procedure. Our framework can be integrated with a wide variety of harmonization models based on deep neural networks, such as the recently proposed conditional variational autoencoder (cVAE) harmonization model. Three datasets from three different continents with a total of 2787 participants and 10,085 anatomical T1 scans were used for evaluation. We found that cVAE removed more dataset differences than the widely used ComBat model, but at the expense of removing desirable biological information as measured by downstream prediction of mini mental state examination (MMSE) scores and clinical diagnoses. On the other hand, our goal-specific cVAE (gcVAE) was able to remove as much dataset differences as cVAE, while improving downstream cross-sectional prediction of MMSE scores and clinical diagnoses.Functional MRI (fMRI) has been widely used to examine changes in neuronal activity during cognitive tasks. Commonly used measures of gray matter macrostructure (e.g., cortical thickness, surface area, volume) do not consistently appear to serve as structural correlates of brain function. In contrast, gray matter microstructure, measured using neurite orientation dispersion and density imaging (NODDI), enables the estimation of indices of neurite density (neurite density index; NDI) and organization (orientation dispersion index; ODI) in gray matter. Our study explored the relationship among neurite architecture, BOLD (blood-oxygen-level-dependent) fMRI, and cognition, using a large sample (n = 750) of young adults of the human connectome project (HCP) and two tasks that index more cortical (working memory) and more subcortical (emotion processing) targeting of brain functions. Using NODDI, fMRI, structural MRI and task performance data, hierarchical regression analyses revealed that higher working memory- and emotion processing-evoked BOLD activity was related to lower ODI in the right DLPFC, and lower ODI and NDI values in the right and left amygdala, respectively. Common measures of brain macrostructure (i.e., DLPFC thickness/surface area and amygdala volume) did not explain any additional variance (beyond neurite architecture) in BOLD activity. A moderating effect of neurite architecture on the relationship between emotion processing task-evoked BOLD response and performance was observed. Our findings provide evidence that neuro-/social-affective cognition-related BOLD activity is partially driven by the local neurite organization and density with direct impact on emotion processing. In vivo gray matter microstructure represents a new target of investigation providing strong potential for clinical translation.
Co-occurrence of posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) is common and concurrent treatment is recommended. Relatively little is known about which evidence-based psychotherapies for PTSD are most effective for patients with varying substance use profiles. We aim to examine the comparative effectiveness of trauma-focused therapy (TFT) and non-trauma-focused therapy (NTFT) among Veterans with PTSD and SUD. TFT has been found to be effective among those with PTSD/SUD, though effects are smaller and rates of treatment non-completion are higher than in those without SUD. SP-2577 datasheet NTFTs suggested for the treatment of PTSD, such as Present Centered Therapy, (PCT) have not been examined among those with co-occurring SUD, despite lower rates of treatment dropout. We will also examine the comparative effectiveness of TFT and NTFT for patients with varying SUD severity, type of substances used, and patient treatment preference.
420 Veterans with PTSD and SUD will be randomized in a prospective, pragmatic comparative effectiveness trial at 14 Veterans Health Administration facilities.
