Genital Pain and the Spectrum of Bladder-Related Symptoms: Findings from the Prevention of Lower Urinary Tract Symptoms Research Consortium RISE FOR HEALTH Study, USA.

INTRODUCTION AND HYPOTHESIS: Women with vulvovaginal or genital pain more commonly experience interstitial cystitis/bladder pain syndrome (IC/BPS) and urinary tract infections. However, the relationship between genital pain and bladder health is lacking. METHODS: Women in the Prevention of Lower Urinary Tract Symptoms Consortium's RISE FOR HEALTH population-based study answered questions about bladder health globally, and across nine bladder health domains of holding, efficacy, social-occupation, physical activity, intimacy, travel, emotion, perception, and freedom. Bladder function was assessed across six indices including urinary frequency, sensation, continence, comfort, emptying, and dysbiosis (e.g., urinary tract infections). Participants were grouped by no pain beyond transitory events (i.e., minor headaches, toothaches, or sprains), nongenital-related pain only, and any genital pain using a validated pain diagram. Mean adjusted scores and indices were compared using general linear modelling. RESULTS: Of 1,973 eligible women, 250 (12.7%) reported genital pain, 609 (30.9%) reported nongenital pain only, and 1,114 (56.5%) reported no pain. Women with any genital pain had lower (worse) adjusted mean scores across all bladder health scales (BHS; BHS global adjusted mean 47.5; 95% CI 40.8-54.1), compared with those with nongenital pain only (53.7; 95% CI 47.6-59.8), and no pain (59.3; 95% CI 53.3-65.4). Similarly, adjusted mean total Bladder Functional Index scores were lower for those with genital pain (63.1; 95% CI 58.4-67.9) compared with nongenital pain (72.1; 95% CI 67.7-76.5) and no pain (77.4; 95% CI 73.0-81.8). CONCLUSIONS: Heightened awareness of the relationship between genital pain and bladder health should prompt clinicians caring for women with genital pain to assess bladder health and function.

Choriocapillaris Impairment, Visual Function, and Distance to Fovea in Aging and Age-Related Macular Degeneration: ALSTAR2 Baseline.

Purpose: In aging and early-intermediate age-related macular degeneration (AMD), rod-mediated dark adaptation (RMDA) slows more at 5° superior than at 12°. Using optical coherence tomography angiography (OCTA), we asked whether choriocapillaris flow deficits are related to distance from the fovea. Methods: Persons ≥60 years stratified for AMD via the Age-Related Eye Disease Study's nine-step system underwent RMDA testing. Two adjacent 4.4° × 4.4° choriocapillaris OCTA slabs were centered on the fovea and 12° superior. Flow signal deficits (FD%) in concentric arcs (outer radii in mm, 0.5, 1.5, 2.2, 4.0, and 5.0 superior) were correlated with rod intercept time (RIT) and best-corrected visual acuity (BCVA). Results: In 366 eyes (170 normal, 111 early AMD, 85 intermediate AMD), FD% was significantly worse with greater AMD severity in all regions (overall P < 0.05) and poorest under the fovea (P < 0.0001). In pairwise comparisons, FD% worsened with greater AMD severity (P < 0.05) at distances <2.2 mm. At greater distances, eyes with intermediate, but not early AMD differed from normal eyes. Foveal FD% was more strongly associated with longer RIT at 5° (r = 0.52) than RIT at 12° (r = 0.39) and BCVA (r = 0.21; all P < 0.0001). Choroidal thickness was weakly associated with longer RIT at 5° and 12° (r = 0.10-0.20, P < 0.05) and not associated with AMD severity. Conclusions: Reduced transport across the choriocapillaris-Bruch's membrane-retinal pigment epithelium complex, which contributes to drusen formation under the macula lutea (and fovea), may also reduce retinoid resupply to rods encircling the high-risk area. FD% has potential as a functionally validated imaging biomarker for AMD emergence.

Does Insurance Provide Adequate Coverage for Physical Therapy Visits for Common Orthopedic Diagnoses? A Survey Study.

OBJECTIVES: This study aimed to analyze the association between physical therapists' recommended number of visits for a full recovery from common orthopedic injuries/surgeries and the extent of insurance coverage for these visits. METHODS: A prospective observational study was conducted with board-certified physical therapists. A qualitative questionnaire was used to gather physical therapists' demographics and the recommended number of physical therapy visits to achieve a full recovery after 11 common orthopedic diagnoses. Physical therapists also were asked to report whether they believe that insurance provides an adequate number of visits overall. In addition to the qualitative survey, insurance coverage details of major Alabama companies were obtained for comparison. Descriptive statistics of the participating therapists were analyzed for sex, age, degree/training, and years of experience. Kruskal-Wallis statistics were used to analyze variance between the aforementioned groupings when compared with the reported average number of sessions. RESULTS: The survey (N = 251) collected data on the average number of physical therapy sessions that are necessary for a complete recovery as recommended by physical therapists for 11 common orthopedic diagnoses. From this survey, the average number of necessary visits ranged from 11.3 visits (ankle sprains) to 37.3 visits (anterior cruciate ligament reconstruction), with the overall average number of visits being 23.8. Only 24% of physical therapists believed that insurance companies provided enough coverage. Insurance coverage varied but often required additional procedures to allocate the adequate number of visits for the studied orthopedic pathologies. CONCLUSIONS: The majority of practicing physical therapists in Alabama perceive insufficient insurance coverage for physical therapy visits for most orthopedic diagnoses. This study has implications for healthcare decision making and patient-centered rehabilitation goals. Physicians and physical therapists can use this information to optimize treatment decisions and rehabilitation goals. Patients will benefit from improved physical and economic well-being. This study has the potential to drive further research and influence national insurance policies to better serve patients' needs.

Comparison of Glaucoma Diagnosis by Telemedicine, In-Person Ophthalmologist and Optometrist.

PRECIS: Diagnosis of glaucoma via telemedicine demonstrates moderate agreement with in-person ophthalmologist and optometrist diagnosis, providing evidence that telemedicine is a timely, accurate screening method in settings where an in-person visit may not be feasible. PURPOSE: To compare diagnostic agreement of glaucoma between in-person ophthalmologist (MD), in-person optometrist (OD), and a simulated telemedicine program. PATIENTS AND METHODS: Cross-sectional study of patients with normal optic nerve structural and functional imaging and new patients referred for glaucoma evaluation examined in-person by an MD for glaucoma with a dilated exam and structural and functional optic nerve testing (optical coherence tomography (OCT)), photos, and visual field); examined in person by an OD with a dilated exam and optic nerve testing; and structural and functional optic nerve testing reviewed separately by two ophthalmologists (TMD1, TMD2) with masking of prior MD and OD diagnoses. MAIN OUTCOME MEASURES: Inter-rater agreement between each diagnostic method (MD, OD, TMD1, TMD2) of normal vs. disease (open angle glaucoma, normal tension glaucoma, other type of glaucoma, other optic nerve disorders, ocular hypertension, glaucoma suspect) for each eye was calculated (Cohen's unweighted kappa). RESULTS: A total of 100 patients with median age of 66 years (IQR 59-72), male (40%) and White (62%) were analyzed. There was moderate agreement between MD and telemedicine [TMD1 kappa 0.49 (95% CI 0.37-0.61), TMD2 kappa 0.44 (95% CI 0.32-0.56)] and between MD and OD diagnosis [0.41 (95% CI 0.28-0.54)] and fair-moderate agreement between OD and telemedicine (TMD1 0.46 (95% CI 0.34-0.58), TMD2 0.61 (95% CI 0.50-0.72)]. CONCLUSIONS: The simulated telemedicine approach had comparable levels of agreement in glaucoma diagnosis with in-person fellowship-trained ophthalmologist, presenting a crucial complementary role in screening and increasing access to care, particularly in rural or underserved settings.

Nonoperative Management of Isolated Thoracolumbar Flexion Distraction Injuries: A Single-Center Study.

BACKGROUND: Nonoperative management is an appealing option for purely transosseous thoracolumbar flexion-distraction injuries given the prospects of osseous healing and restoration of the posterior tension band complex. This study seeks to examine differences in outcomes following flexion-distraction injuries after operative and nonoperative management. METHODS: This study reviews all patients at a single Level 1 trauma center from 2004 to 2022 with AO Spine B1 thoracolumbar injuries treated operatively vs nonoperatively. Inclusion criteria were age greater than 16 years, computed tomography-confirmed transosseous flexion-distraction injuries, and at least 3 months of follow-up with available imaging. The primary outcome assessed was a change in local Cobb angles, with secondary outcomes consisting of complications, time to return to work, and need for subsequent operative fixation. RESULTS: Initial Cobb angles in the operative (n = 14) vs nonoperative group (n = 13) were -5° and -13°, respectively (P = 0.225), indicating kyphotic alignment in both cohorts. We noted a significant difference in Cobb angles between cohorts at first follow-up (2.6° and -13.9°, P = 0.015) and within the operative cohort from presentation to first follow-up (P = 0.029). At the second follow-up, there was no significant difference in Cobb angles between cohorts (3.6° and -12.6°, P = 0.07). No significant differences were noted in complication rates (P = 1), time to return to work (P = 0.193), or resolution of subjective back pain (P = 0.193). No crossover was noted. CONCLUSIONS: Nonoperative management of minimally displaced transosseous flexion-distraction injuries is a safe alternative to surgery. Patient factors, such as compliance with follow-up, and location of the injury should be factored into the surgeon's management recommendation. CLINICAL RELEVANCE: Overall, no significant differences in outcomes and complications were noted following nonoperative management of AO Spine B1 injuries, indicating the potential for these injuries to be managed conservatively.

Lower Urinary Tract Symptoms in US Women: Contemporary Prevalence Estimates from the RISE FOR HEALTH Study.

PURPOSE: We aimed to estimate the prevalence of a wide range of lower urinary tract symptoms (LUTS) in US women, and explore associations with bother and discussion with health care providers, friends, and family. MATERIALS AND METHODS: We analyzed baseline data collected from May 2022 to December 2023 in the RISE FOR HEALTH study-a large, regionally representative cohort study of adult female community members. LUTS and related bother were measured by the 10-item Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index, and discussion was assessed by a study-specific item. RESULTS: Of the 3000 eligible participants, 73% (95% CI 71%-74%) reported any storage symptoms, 52% (95% CI 50%-53%) any voiding or emptying symptoms, and 11% (95% CI 10%-13%) any pain with bladder filling, for an overall LUTS prevalence of 79% (95% CI 78%-81%). This prevalence estimate included 43% (95% CI 41%-45%) of participants with mild to moderate symptoms and 37% (95% CI 35%-38%) with moderate to severe symptoms. Over one-third of participants reported LUTS-related bother (38%, 95% CI 36%-39%) and discussion (38%, 95% CI 36%-40%), whereas only 7.1% (95% CI 6.2%-8.1%) reported treatment. Urgency and incontinence (including urgency and stress incontinence) were associated with the greatest likelihood of bother and/or discussion (adjusted prevalence ratios = 1.3-2.3), even at mild to moderate levels. They were also the most commonly treated LUTS. CONCLUSIONS: LUTS, particularly storage LUTS such as urgency and incontinence, were common and bothersome in the RISE study population, yet often untreated. Given this large burden, both prevention and treatment-related interventions are warranted to reduce the high prevalence and bother of LUTS.

Outer Retinal Thickness Is Associated With Cognitive Function in Normal Aging to Intermediate Age-Related Macular Degeneration.

Purpose: Research on Alzheimer's disease (AD) and precursor states demonstrates a thinner retinal nerve fiber layer (NFL) compared to age-similar controls. Because AD and age-related macular degeneration (AMD) both impact older adults and share risk factors, we asked if retinal layer thicknesses, including NFL, are associated with cognition in AMD. Methods: Adults ≥ 70 years with normal retinal aging, early AMD, or intermediate AMD per Age-Related Eye Disease Study (AREDS) nine-step grading of color fundus photography were enrolled in a cross-sectional study. Optical coherence tomography (OCT) volumes underwent 11-line segmentation and adjustments by a trained operator. Evaluated thicknesses reflect the vertical organization of retinal neurons and two vascular watersheds: NFL, ganglion cell layer-inner plexiform layer complex (GCL-IPL), inner retina, outer retina (including retinal pigment epithelium-Bruch's membrane), and total retina. Thicknesses were area weighted to achieve mean thickness across the 6-mm-diameter Early Treatment of Diabetic Retinopathy Study (ETDRS) grid. Cognitive status was assessed by the National Institutes of Health Toolbox cognitive battery for fluid and crystallized cognition. Correlations estimated associations between cognition and thicknesses, adjusting for age. Results: Based on 63 subjects (21 per group), thinning of the outer retina was significantly correlated with lower cognition scores (P < 0.05). No other retinal thickness variables were associated with cognition. Conclusions: Only the outer retina (photoreceptors, supporting glia, retinal pigment epithelium, Bruch's membrane) is associated with cognition in aging to intermediate AMD; NFL was not associated with cognition, contrary to AD-associated condition reports. Early and intermediate AMD constitute a retinal disease whose earliest, primary impact is in the outer retina. Our findings hint at a unique impact on the brain from the outer retina in persons with AMD.

Teprotumumab Related Hearing Loss: A Large-Scale Analysis and Review of Voluntarily Reported Patient Complaints to the Food and Drug Administration (FDA).

PURPOSE: Accumulating case reports and series have suggested that teprotumumab may significantly increase the risk of hearing impairment that, in some cases, does not resolve. This study investigates the association between hearing impairment and teprotumumab use. METHODS: A disproportionality analysis was conducted using the United States Food and Drug Administration Adverse Event Reporting System, a publicly accessible database used for postmarketing surveillance and research. All adverse event reports containing the terms "teprotumumab" or "Tepezza" and a similar comparison group from all patients with the same indications for teprotumumab use (e.g., autoimmune thyroiditis, endocrine ophthalmopathy, and hyperthyroidism) but who had not received the drug were selected. Hearing impairment events were identified using the hearing impairment Standardized MedDRA Query. RESULTS: A total of 940 teprotumumab-associated adverse events were identified, including 84 hearing-related adverse events, with the first reported to the Food and Drug Administration in April 2020. A comparison group of 32,794 nonteprotumumab adverse events was identified with 127 hearing-related adverse events reported. Use of teprotumumab in patients with thyroid conditions was associated with a nearly 24-fold (proportional reporting ratio [PRR] 23.6, 95% confidence interval [CI]: 18.1-30.8) increased likelihood of any hearing disorder (p value <0.0001). The association was specifically elevated for a variety of deafness conditions (e.g., bilateral deafness [PRR: 41.9; 95% CI: 12.8-136.9]), Eustachian tube disorders (PRR: 34.9; 95% CI: 4.9-247.4), hypoacusis (PRR: 10.1; 95% CI: 7.6-13.3), and tinnitus (PRR: 8.7; 95% CI: 6.2-12.1). CONCLUSIONS: Patients treated with teprotumumab should receive warnings regarding the increased risk of hearing-related impairments and receive audiometry before, during, and after treatment.

Telemedicine Screening for Eye Disorders in Federally Qualified Health Centers: Relationship to Vision-Targeted Health-Related Quality of Life.

Introduction: Federally Qualified Health Centers (FQHCs) play a crucial role as safety-net primary health care clinics in the United States, serving medically underserved areas and populations. However, eye services are rarely offered at FQHCs. We examined how telemedicine-generated ocular diagnoses impacted vision-targeted health-related quality of life at FQHCs in rural Alabama. Methods: We focused on patients who are at risk for glaucoma. Both visual function and retinal imaging were assessed. The telemedicine vision screening protocol performed by a remote ophthalmologist evaluated eyes for glaucoma, diabetic retinopathy, cataract, age-related macular degeneration, and a measurement of habitual visual acuity. The National Eye Institute Visual Function Questionnaire-9 (VFQ-9) was administered. Results: Using stepwise regression, the best-fitting model for predicting VFQ-9 scores incorporated visual acuity 20/40 or worse, a diabetic retinopathy diagnosis, and sociodemographic variables (gender, transportation, insurance type/status, and employment status). Conclusion: Vision-targeted, health-related quality of life in our FQHC settings was related to the visual acuity impairment and the diagnosis of diabetic retinopathy but was also influenced by a variety of sociodemographic factors.

Quantitative Autofluorescence at AMD's Beginnings Highlights Retinal Topography and Grading System Differences: ALSTAR2 Baseline.

INTRODUCTION: The aims of the study were to describe baseline quantitative (short-wavelength) autofluorescence (qAF) findings in a large pseudophakic cohort at age-related macular degeneration (AMD)'s beginnings and to assess qAF8 as an outcome measure and evaluate Age-Related Eye Disease Study (AREDS) and Beckman grading systems. METHODS: In the ALSTAR2 baseline cohort (NCT04112667), 346 pseudophakic eyes of 188 persons (74.0 ± 5.5 years) were classified as normal (N = 160 by AREDS, 158 by Beckman), early AMD (eAMD) (N = 104, 66), and intermediate AMD (iAMD) (N = 82, 122). Groups were compared via mean qAF intensities in a 6°-8° annulus (qAF8) and maps of differences between observations and the overall mean, divided by standard deviation (Z-score). RESULTS: qAF8 did not differ significantly among diagnostic groups by either stratification (p = 0.0869 AREDS; p = 0.0569 by Beckman). Notably, 45 eyes considered eAMD by AREDS became iAMD by Beckman. For AREDS-stratified eyes, Z-score maps showed higher centrally located qAF for normal, near the mean in eAMD, and lower values for iAMD. Maps deviated from this pattern for Beckman-stratified eyes. CONCLUSIONS: In a large sample of pseudophakic eyes, qAF8 does not differ overall from normal aging to iAMD but also does not capture the earliest AMD activity in the macula lutea. AREDS classification gives results more consistent with a slow decline in histologic autofluorescence than Beckman classification.

Non-lesional epilepsy does not necessarily convey poor outcomes after invasive monitoring followed by resection or thermal ablation.

OBJECTIVE: We aimed to compare outcomes including seizure-free status at the last follow-up in adult patients with medically refractory focal epilepsy identified as lesional vs. non-lesional based on their magnetic resonance imaging (MRI) findings who underwent invasive evaluation followed by subsequent resection or thermal ablation (LiTT). METHODS: We identified 88 adult patients who underwent intracranial monitoring between 2014 and 2021. Of those, 40 received resection or LiTT, and they were dichotomized based on MRI findings, as lesional (N = 28) and non-lesional (N = 12). Patient demographics, seizure characteristics, non-invasive interventions, intracranial monitoring, and surgical variables were compared between the groups. Postsurgical seizure outcome at the last follow-up was rated according to the Engel classification, and postoperative seizure freedom was determined by Kaplan-Meyer survival analysis. Statistical analyses employed Fisher's exact test to compare categorical variables, while a t-test was used for continuous variables. RESULTS: There were no differences in baseline characteristics between groups except for more often noted PET abnormality in the lesional group (p = 0.0003). 64% of the lesional group and 57% of the non-lesional group received surgical resection or LiTT (p = 0.78). At the last follow-up, 78.5% of the patients with lesional MRI findings achieved Engel I outcomes compared to 66.7% of non-lesional patients (p = 0.45). Kaplan-Meier curves did not show a significant difference in seizure-free duration between both groups after surgical intervention (p = 0.49). SIGNIFICANCE: In our sample, the absence of lesion on brain MRI was not associated with worse seizure outcomes in adult patients who underwent invasive intracranial monitoring followed by resection or thermal ablation.

Repeatability of Rod-Mediated Dark Adaptation Testing in Normal Aging and Early and Intermediate Age-Related Macular Degeneration.

PURPOSE: The vulnerability of rod photoreceptors in aging and early and intermediate age-related macular degeneration (AMD) has been well documented. Rod-mediated dark adaptation (RMDA) is a measure of the recovery of light sensitivity in rod photoreceptors following a bright light. Delays in RMDA during early and intermediate AMD have been widely reported. For RMDA's promise as an outcome for trials targeted at early and intermediate AMD to be realized, excellent test-retest reliability, its repeatability, must be established. METHODS: Test-retest performance in a commonly used RMDA test based on the rod intercept time metric (RIT) was evaluated in participants with early and intermediate AMD and with normal retinal aging with testing approximately 2 weeks apart. The test target was placed at 5° eccentricity superior to the foveal center, an area with maximal rod loss in aging and AMD. Disease severity was identified by a trained and masked grader of fundus photographs using both the AREDS 9-step and Beckman classification systems. Bland-Altman plots and intra-class correlation coefficients (ICC) evaluated repeatability. RESULTS: The analysis sample consisted of 37 older adults (mean age 76 years, standard deviation 5), with approximately one-third of the sample in each of three groups - normal aging, early AMD, and intermediate AMD. For the total sample, the ICC was 0.98. For individual AMD groups for both AREDS 9-step and Beckman classifications, the ICCs were also very high ranging from 0.82 to 0.99. CONCLUSION: We demonstrated that RMDA testing using the RIT metric has excellent repeatability when target location is at 5° in studying older adults from normal aging to intermediate AMD, suggesting the reliable use of this functional measure in trials.

MSG-15: Super-Bioavailability Itraconazole Versus Conventional Itraconazole in the Treatment of Endemic Mycoses-A Multicenter, Open-Label, Randomized Comparative Trial.

Background: Invasive fungal disease caused by dimorphic fungi is associated with significant morbidity and mortality. Super-bioavailability itraconazole (SUBA-itra) is a novel antifungal agent with pharmacokinetic advantages over currently available formulations. In this prospective comparative study, we report the outcomes of patients with endemic fungal infections (histoplasmosis, blastomycosis, coccidioidomycosis, and sporotrichosis). Methods: This open-label randomized trial evaluated the efficacy, safety, and pharmacokinetics SUBA-itra compared with conventional itraconazole (c-itra) treatment for endemic fungal infections. An independent data review committee determined responses on treatment days 42 and 180. Results: Eighty-eight patients were enrolled for IFD (SUBA-itra, n = 42; c-itra, n = 46) caused by Histoplasma (n = 51), Blastomyces (n = 18), Coccidioides (n = 13), or Sporothrix (n = 6). On day 42, clinical success was observed with SUBA-itra and c-itra on day 42 (in 69% and 67%, respectively, and on day 180 (in 60% and 65%). Patients treated with SUBA-itra exhibited less drug-level variability at days 7 (P = .03) and 14 (P = .06) of randomized treatment. The concentrations of itraconazole and hydroxyitraconazole were comparable between the 2 medications (P = .77 and P = .80, respectively). There was a trend for fewer adverse events (AEs; 74% vs 87%, respectively; P = .18) and serious AEs (10% vs 26%; P = .06) in the SUBA-itra-treated patients than in those receiving c-itra. Serious treatment-emergent AEs were less common in SUBA-itra-treated patients (12% vs 50%, respectively; P < .001). Conclusions: SUBA-itra was bioequivalent, well tolerated, and efficacious in treating endemic fungi, with a more favorable safety profile than c-itra. Clinical Trials Registration: NCT03572049.

Workplace Violence in Orthopaedic Surgery: A Survey of Academy of Orthopaedic Surgeons Membership.

INTRODUCTION: Workplace violence (WPV) in US health care is increasing, and many workers are likely to experience WPV during their careers. This study aims to assess the scope of WPV in orthopaedics. METHODS: A 20-item survey adopted from the World Health Organization's 'Workplace Violence in the Health Sector Country Case Studies Research Instruments Survey Questionnaire' was sent to Academy of Orthopaedic Surgeons members, including residents and fellows. Deidentified responses were collected electronically over a 1-month period and assessed. RESULTS: Overall, 1,125 Academy of Orthopaedic Surgeons members participated (5% response rate). Most respondents were male (86%) and identified with the majority ethnic group (80%). WPV of any type was reported by 77.1%. Verbal abuse was the most common type (71.6%), and patients were the most common perpetrators. WPV was most prevalent among traumatologists, tumor surgeons, female surgeons, and those with 0 to 15 years in practice. Female surgeons reported more WPV events per practice year (2.25 versus 0.65, P < 0.01) and increased likelihood of physical threats and physical assaults from coworkers ( P = 0.004). DISCUSSION: WPV in orthopaedic surgery is largely perpetrated by patients and directed toward traumatologists, tumor surgeons, female surgeons, and less experienced surgeons. These data can be used to address safety measures in the workplace.

Water Decontamination Products for Wound Irrigation in Austere Environments: Benchtop Evaluation and Recommendations.

BACKGROUND: Irrigation is used to minimize infection of open wounds. Sterile saline is preferred, but potable water is becoming more widely accepted. However, the large volumes of water that are recommended are usually not available in austere environments. This study determined the long-term antimicrobial effectiveness of military purification powder compared with currently available civilian methods. The study also compared the physical characteristics and outcomes under the logistical constraints. METHODS: Six commercially available water decontamination procedures were used to decontaminate five different sources of water (pond water, river water, inoculated saline, tap water, and sterile saline). Each product was evaluated based on six different parameters: bacterial culture, pH, turbidity, cost, flow rate, and size. RESULTS: All methods of treatment decreased the bacterial count below the limit of detection. However, they had variable effects on pH and turbidity of the five water sources. Prices ranged from $7.95 to $350, yielding 10-10,000L of water, and weighing between 18 and 500g. CONCLUSION: In austere settings, where all equipment is carried manually, no single decontamination device is available to optimize all the measured parameters. Since all products effectively reduced microbial levels, their size, cost, and production capability should be evaluated for the intended application.

Racial Disparities in Treatment and Outcomes of Patients With Hepatitis C Undergoing Elective Total Joint Arthroplasty.

BACKGROUND: African Americans have the highest prevalence of chronic Hepatitis C virus (HCV) infection. Racial disparities in outcome are observed after elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). This study sought to identify if disparities in treatments and outcomes exist between Black and White patients who have HCV prior to elective THA and TKA. METHODS: Patient demographics, comorbidities, HCV characteristics, perioperative variables, in-hospital outcomes, and postoperative complications at 1-year follow-up were collected and compared between the 2 races. Patients who have preoperative positive viral load (PVL) and undetectable viral load were identified. Chi-square and Fisher's exact tests were used to compare categorical variables, while 2-tailed Student's Kruskal-Wallis t-tests were used for continuous variables. A P value of less than .05 was statistically significant. RESULTS: The liver function parameters, including aspartate aminotransferase and model for end-stage liver disease scores, were all higher preoperatively in Black patients undergoing THA (P = .01; P < .001) and TKA (P = .03; P = .003), respectively. Black patients were more likely to undergo THA (65.8% versus 35.6%; P = .002) and TKA (72.1% versus 37.3%; 0.009) without receiving prior treatment for HCV. Consequently, Black patients had higher rates of preoperative PVL compared to White patients in both THA (66% versus 38%, P = .006) and TKA (72% versus 37%, P < .001) groups. Black patients had a longer length of stay for both THA (3.7 versus 3.3; P = .008) and TKA (4.1 versus 3.0; P = .02). CONCLUSIONS: The HCV treatment prior to THA and TKA with undetectable viral load has been shown to be a key factor in mitigating postoperative complications, including joint infection. We noted that Black patients were more likely to undergo joint arthroplasty who did not receive treatment and with a PVL. While PVL rates decreased over time for both races, a significant gap persists for Black patients.

A Shadow of Doubt: Is There Implicit Bias Among Orthopaedic Surgery Faculty and Residents Regarding Race and Gender?

BACKGROUND: Orthopaedic surgery continues to be one of the least diverse medical specialties. Recently, increasing emphasis has been placed on improving diversity in the medical field, which includes the need to better understand existing biases. Despite this, only about 6% of orthopaedic surgeons are women and 0.3% are Black. Addressing diversity, in part, requires a better understanding of existing biases. Most universities and residency programs have statements and policies against discrimination that seek to eliminate explicit biases. However, unconscious biases might negatively impact the selection, training, and career advancement of women and minorities who are underrepresented in orthopaedic surgery. Although this is difficult to measure, the Implicit Association Test (IAT) by Project Implicit might be useful to identify and measure levels of unconscious bias among orthopaedic surgeons, providing opportunities for additional interventions to improve diversity in this field. QUESTIONS/PURPOSES: (1) Do orthopaedic surgeons demonstrate implicit biases related to race and gender roles? (2) Are certain demographic characteristics (age, gender, race or ethnicity, or geographic location) or program characteristics (geographic location or size of program) associated with the presence of implicit biases? (3) Do the implicit biases of orthopaedic surgeons differ from those of other healthcare providers or the general population? METHODS: A cross-sectional study of implicit bias among orthopaedic surgeons was performed using the IAT from Project Implicit. The IAT is a computerized test that measures the time required to associate words or pictures with attributes, with faster or slower response times suggesting the ease or difficulty of associating the items. Although concerns have been raised recently about the validity and utility of the IAT, we believed it was the right study instrument to help identify the slight hesitation that can imply differences between inclusion and exclusion of a person. We used two IATs, one for Black and White race and one for gender, career, and family roles. We invited a consortium of researchers from United States and Canadian orthopaedic residency programs. Researchers at 34 programs agreed to distribute the invitation via email to their faculty, residents, and fellows for a total of 1484 invitees. Twenty-eight percent (419) of orthopaedic surgeons and trainees completed the survey. The respondents were 45% (186) residents, 55% (228) faculty, and one fellow. To evaluate response biases, the respondent population was compared with that of the American Academy of Orthopaedic Surgeons census. Responses were reported as D-scores based on response times for associations. D-scores were categorized as showing strong (≥ 0.65), moderate (≥ 0.35 to < 0.65), or slight (≥ 0.15 to < 0.35) associations. For a frame of reference, orthopaedic surgeons' mean IAT scores were compared with historical scores of other self-identified healthcare providers and that of the general population. Mean D-scores were analyzed with the Kruskal-Wallis test to determine whether demographic characteristics were associated with differences in D-scores. Bonferroni correction was applied, and p values less than 0.0056 were considered statistically significant. RESULTS: Overall, the mean IAT D-scores of orthopaedic surgeons indicated a slight preference for White people (0.29 ± 0.4) and a slight association of men with career (0.24 ± 0.3), with a normal distribution. Hence, most respondents' scores indicated slight preferences, but strong preferences for White race were noted in 27% (112 of 419) of respondents. There was a strong association of women with family and home and an association of men with work or career in 14% (60 of 419). These preferences generally did not correlate with the demographic, geographic, and program variables that were analyzed, except for a stronger association of women with family and home among women respondents. There were no differences in race IAT D-scores between orthopaedic surgeons and other healthcare providers and the general population. Gender-career IAT D-scores associating women with family and home were slightly lower among orthopaedic surgeons (0.24 ± 0.3) than among the general population (0.32 ± 0.4; p < 0.001) and other healthcare professionals (0.34 ± 0.4; p < 0.001). All of these values are in the slight preference range. CONCLUSION: Orthopaedic surgeons demonstrated slight preferences for White people, and there was a tendency to associate women with career and family on IATs, regardless of demographic and program characteristics, similar to others in healthcare and the general population. Given the similarity of scores with those in other, more diverse areas of medicine, unconscious biases alone do not explain the relative lack of diversity in orthopaedic surgery. CLINICAL RELEVANCE: Implicit biases only explain a small portion of the lack of progress in improving diversity, equity, inclusion, and belonging in our workforce and resolving healthcare disparities. Other causes including explicit biases, an unwelcoming culture, and perceptions of our specialty should be examined. Remedies including engagement of students and mentorship throughout training and early career should be sought.

The Impact of Smoking on Hospital Course and Postoperative Outcomes in Patients With Fracture-Related Infections.

OBJECTIVES: To assess the relationship between patient smoking status and fracture-related infection (FRI) characteristics including patient symptoms at FRI presentation, bacterial species of FRI, and rates of fracture union. DESIGN: Retrospective cohort study. SETTING: Urban level 1 trauma center. PATIENT SELECTION CRITERIA: All patients undergoing reoperation for FRI from January 2013 to April 2021 were identified through manual review of an institutional database. OUTCOME MEASURES AND COMPARISONS: Data including patient demographics, fracture characteristics, infection presentation, and hospital course were collected through review of the electronic medical record. Patients were grouped based on current smoker versus nonsmoker status. Hospital course and postoperative outcomes of these groups were then compared. Risk factors of methicillin-resistant Staphylococcus aureus (MRSA) infection, Staphylococcus epidermidis infection, and sinus tract development were evaluated using multivariable logistic regression. RESULTS: A total of 301 patients, comprising 155 smokers (51%) and 146 nonsmokers (49%), undergoing FRI reoperation were included. Compared with nonsmokers, smokers were more likely male (69% vs. 56%, P = 0.024), were younger at the time of FRI reoperation (41.7 vs. 49.5 years, P < 0.001), and had lower mean body mass index (27.2 vs. 32.0, P < 0.001). Smokers also had lower prevalence of diabetes mellitus (13% vs. 25%, P = 0.008) and had higher Charlson Comorbidity Index 10-year estimated survival (93% vs. 81%, P < 0.001). Smokers had a lower proportion of S. epidermidis infections (11% vs. 20%, P = 0.037), higher risk of nonunion after index fracture surgery (74% vs. 61%, P = 0.018), and higher risk of sinus tracts at FRI presentation (38% vs. 23%, P = 0.004). On multivariable analysis, smoking was not found to be associated with increased odds of MRSA infection. CONCLUSIONS: Among patients who develop a FRI, smokers seemed to have better baseline health regarding age, body mass index, diabetes mellitus, and Charlson Comorbidity Index 10-year estimated survival compared with nonsmokers. Smoking status was not significantly associated with odds of MRSA infection. However, smoking status was associated with increased risk of sinus tract development and nonunion and lower rates of S. epidermidis infection at the time of FRI reoperation.

The economic and clinical impact of fast- versus slow-setting cement in primary total knee arthroplasty.

INTRODUCTION: New bone cement products have been developed attempting to shorten their setting time and thus cut down time in the operating room. This study determines whether faster-setting bone cement shortens time in the operating room, and whether the quantity used compromises postoperative TKA outcomes. Additionally, this study looks at cost analyses of the quantity of bone cement used in TKA procedures. MATERIALS AND METHODS: One-hundred and sixty patients at a single institution with primary TKA surgeries between January 2019 and December 2021, and a clinic follow-up of at least one year, were identified. Five cement products used in this time period were identified and categorized by fast- or slow-setting products if their set times were marketed below or above six minutes, respectively. RESULTS: Estimated blood loss was higher in patients receiving fast-setting cements (160.0 vs 126.4 mL; p = 0.0009); however, operative time showed no difference between the cohorts (88.2 vs 89.2 min; p = 0.99). Fewer bags of cement were used for the fast cohort (1.3 vs 1.8 bags; p < 0.0001). The fast group was significantly cheaper on average per patient only when comparing between antibiotic bone cements (p = 0.007). No differences were found in postoperative outcomes between the two groups. CONCLUSIONS: No differences were found in operative times between the fast and slow cemented groups. Fewer bags of faster-setting cement only proved cost saving relative to other antibiotic bone cements studied. Nonetheless, decreased usage of fast cement did not result in any different postoperative outcomes compared to slow cements. LEVEL OF EVIDENCE: III.
