Early outcomes after first reverse total shoulder arthroplasty better prognosticate contralateral success compared with early outcomes after anatomic total shoulder arthroplasty. J Shoulder Elbow Surg 2024; 33:1331-1339. [PMID: 38000731 DOI: 10.1016/j.jse.2023.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 09/26/2023] [Accepted: 10/16/2023] [Indexed: 11/26/2023]
Abstract
BACKGROUND The ideal timing between bilateral total shoulder arthroplasty (TSA) is unclear. The purpose of this study is to determine whether early outcomes after first TSA can be used to predict clinical outcomes after TSA of the contralateral shoulder and to evaluate the ideal time after TSA to perform the contralateral shoulder. METHODS A single-institution prospectively collected shoulder arthroplasty database was reviewed. Patients who underwent bilateral primary anatomic or reverse TSA (aTSA + rTSA) without an indication of fracture, tumor, or infection were identified. Included patients had minimum 2-year follow-up on their second TSA and postoperative follow-up after their first TSA at 3 months, 6 months, 1 year, or 2 years. Our primary outcome was whether outcome scores and motion at 3-month, 6-month, 1-year, and 2-year follow-up after first TSA predicted clinical success after second TSA at final follow-up, defined as achieving the patient acceptable symptomatic state (PASS = the highest level of symptoms beyond which patients consider themselves well). Outcomes included the American Shoulder and Elbow Surgeons and Constant scores, abduction, forward elevation, and external/internal-rotation. Multivariable logistic regression determined whether postoperative outcomes after first TSA were predictive of achieving the PASS after second TSA independent of age, sex, and body mass index. Receiver operating characteristic analysis determined cutoffs of postoperative outcomes after first TSA at each time point that best predicted achieving the prosthesis-specific PASS after second TSA. RESULTS One hundred thirty-four patients were included in the final analysis (110 aTSA and 158 rTSA). Range of motion and outcome scores at late (1- or 2-year) follow-up after first aTSA were more predictive of achieving the second TSA PASS compared with early (3- or 6-month) outcomes. In contrast, outcomes after early and late follow-up after first rTSA were similarly predictive of achieving the second TSA PASS. Specifically, the Constant score threshold at 2 years after first aTSA (79.4; area under the curve [AUC] = 0.804) better differentiated achieving the second TSA PASS vs. the 6-month threshold (72.0; AUC = 0.600). In contrast, the Constant score threshold at 2 years after first rTSA (76.4; AUC = 0.703) was similarly discriminant of achieving the second TSA PASS compared with the 6-month threshold (65.8; AUC = 0.711). CONCLUSIONS Patients with good outcomes after first rTSA can be counseled on contralateral TSA as early as 3 months postoperatively with confidence of a similar result on the contralateral side. In contrast, success after first aTSA does not reliably predict contralateral success until ≥1 year.

Relationship between pulmonary, cough, and swallowing functions in individuals with amyotrophic lateral sclerosis. Muscle Nerve 2024. [PMID: 38742544 DOI: 10.1002/mus.28113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 04/08/2024] [Accepted: 04/28/2024] [Indexed: 05/16/2024]
Abstract
INTRODUCTION/AIMS Evaluations of pulmonary, cough, and swallow function are frequently performed to assess disease progression in amyotrophic lateral sclerosis (ALS), yet the relationship between these functions remains unknown. We therefore aimed to determine relationships between these measures in individuals with ALS. METHODS One hundred individuals with ALS underwent standardized tests: forced vital capacity (FVC), maximum expiratory/inspiratory pressure (MEP, MIP), voluntary cough peak expiratory flow (PEF), and videofluoroscopic swallow evaluation (VF). Duplicate raters completed independent, blinded ratings using the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale. Descriptives, Spearman's Rho correlations, Kruskal-Wallis analyses, and Pearson's chi-squared tests were completed. RESULTS Mean and standard deviation across pulmonary and cough measures were FVC: 74.2% predicted (± 22.6), MEP: 91.6 cmH2O (± 46.4), MIP cmH2O: 61.1 (± 28.9), voluntary PEF: 352.7 L/min (± 141.6). DIGEST grades included: 0 (normal swallowing): 31%, 1 (mild dysphagia): 48%, 2 (moderate dysphagia): 10%, 3 (severe dysphagia): 10%, and 4 (life-threatening dysphagia): 1%. Positive correlations were observed: MEP-MIP: r = .76, MIP-PEF: r = .68, MEP-PEF: r = .61, MIP-FVC: r = .60, PEF-FVC: r = .49, and MEP-FVC: r = .46, p < .0001. MEP (p = .009) and PEF (p = .04) differed across DIGEST safety grades. Post hoc analyses revealed significant between group differences in MEP and PEF across DIGEST safety grades 0 versus 1 and grades 0 versus 3, (p < .05). DISCUSSION In this cohort of individuals with ALS, pulmonary function, and voluntary cough were associated. Expiratory metrics (MEP, PEF) were diminished in individuals with unsafe swallowing, increasing their risk for effectively defending the airway.

Abstract
BACKGROUND Pitch counts are only one measure of the true workload of baseball pitchers. Newer research indicates that workload measurement and prevention of injury must include additional factors. Thus, current monitoring systems gauging pitcher workload may be considered inadequate. PURPOSE/HYPOTHESIS The purpose of this study was to develop a novel method to determine workload in baseball pitchers and improve processes for prevention of throwing-related injuries. It was hypothesized that our pitching workload model would better predict throwing-related injuries occurring throughout the baseball season than a standard pitch count model. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS This prospective observational study was conducted at an academic medical center and community baseball fields during the 2019 to 2023 seasons. Pitchers aged 13 to 18 years were monitored for pitching-related injuries and workload (which included pitching velocity; intensity, using preseason and in-season velocity as a marker of effort; and pitch counts). RESULTS A total of 71 pitchers had 313 recorded pitcher outings, 11 pitching-related injuries, and 24,228 pitches thrown. Gameday pitch counts for all pitchers ranged from 19 to 219 (mean, 77.5 ± 41.0). Velocity ranged from 46.8 to 85.7 mph (mean, 71.3 ± 5.8 mph). Intensity ranged from 0.7 to 1.3 (mean, 1.0 ± 0.08). The mean workload was 74.7 ± 40.1 for all pitchers. Risk factors significant for injury included throwing at a higher velocity in game (P = .001), increased intensity (eg, an increase in mean velocity thrown from preseason to in-season; P < .001), and being an older pitcher (P = .014). No differences were found for workload between injured and noninjured pitchers because the analysis was underpowered. CONCLUSION Our workload model indicated that throwing at a higher velocity, throwing at a higher intensity, and older age were risk factors for injury. Thus, this novel workload model should be considered as a means to identify pitchers who may be at greater risk for injury.

Cell Cycle Checkpoints p16 and p21-Strong Predictors of Clinicopathologic Outcomes in High-Grade Osteosarcoma. Cancer J 2024; 30:133-139.

Abstract
PURPOSE In this study, we used a series of immunohistochemical measurements of 2 cell cycle regulators, p16 and p21, to evaluate their prognostic value, separately and in combination, for the disease outcomes. METHOD A total of 101 patients with high-grade osteosarcoma were included in this study. Clinicopathologic data were collected, and immunohistochemistry for p16 and p21 was performed and interpreted by 3 independent pathologists. Statistical analysis was performed to assess the strength of each of these markers relative to disease outcome. RESULTS Our results indicate that more than 90% expression (high) of p16 by immunohistochemistry on the initial biopsy has a strong predictive value for good histologic response to chemotherapy. The patients are also more likely to survive the past 5 years and less likely to develop metastasis than patients with less than 90% p16 (low) expression. The results for p21, on the other hand, show a unique pattern of relationship to the clinicopathologic outcomes of the disease. Patients with less than 1% (low) or more than 50% (high) expression of p21 by immunohistochemistry show a higher chance of metastasis, poor necrotic response to chemotherapy, and an overall decreased survival rate when compared with p21 expression between 1% and 50% (moderate). Our results also showed that the expression of p16 and combined p16 and p21 demonstrates a stronger predictive relationship to 5-year survival than tumor histologic necrosis and p21 alone. DISCUSSION The results of this study, once proven to be reproducible by a larger number of patients, will be valuable in the initial assessment and risk stratification of the patients for treatment and possibly the clinical trials.

Physical activity positively impacts disability outcomes during transition from midlife to early older age irrespective of body mass index. Arch Gerontol Geriatr 2024; 120:105339. [PMID: 38340391 DOI: 10.1016/j.archger.2024.105339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 01/17/2024] [Accepted: 01/20/2024] [Indexed: 02/12/2024]
Abstract
We examined the effects of physical activity (PA) and body mass index (BMI) longitudinal patterns (trajectories) on subjective measures of mobility, function, and disability in adults and assessed whether effects of PA trajectories on function varied due to BMI. Group-based trajectory analyses were used to determine patterns of change in PA and BMI using data from the Health and Retirement Study 1931-1941 birth cohort (n = 10,507). Physical function was assessed by Mobility Limitations (0-5 scale) and Large Muscle Function (0-4 scale) Indexes, as well as with score for activities of daily living (ADLs) and instrumental activities of daily living (IADLs), with higher scores being worse. Our analyses estimated four distinct PA trajectories: decreasing, (2) fluctuating, (3) stable high, and (4) emergent (previously low/sedentary with increased PA over the study period). Worse mobility limitations, large muscle function, ADLs, and IADLs were associated with Decreasing and Fluctuating PA groups. Better outcomes were associated with Emergent and Stable High PA groups. The five BMI trajectories were stable normal/overweight, modest decreasing, fluctuating, steep decreasing, and increasing. No significant interaction existed between PA and BMI trajectories for Mobility Limitations (P= 0.577), Large Muscle Function (P= 0.511), ADLs (P= 0.600), and IADLs (P= 0.152). These findings may empower clinicians to promote messages to midlifers that meaningful changes in PA can improve function in older age.

Individual Patient Data Meta-Analysis of Dynamic Cerebral Autoregulation and Functional Outcome After Ischemic Stroke. Stroke 2024; 55:1235-1244. [PMID: 38511386 PMCID: PMC7615849 DOI: 10.1161/strokeaha.123.045700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 02/12/2024] [Indexed: 03/22/2024]
Abstract
BACKGROUND The relationship between dynamic cerebral autoregulation (dCA) and functional outcome after acute ischemic stroke (AIS) is unclear. Previous studies are limited by small sample sizes and heterogeneity. METHODS We performed a 1-stage individual patient data meta-analysis to investigate associations between dCA and functional outcome after AIS. Participating centers were identified through a systematic search of the literature and direct invitation. We included centers with dCA data within 1 year of AIS in adults aged over 18 years, excluding intracerebral or subarachnoid hemorrhage. Data were obtained on phase, gain, coherence, and autoregulation index derived from transfer function analysis at low-frequency and very low-frequency bands. Cerebral blood velocity, arterial pressure, end-tidal carbon dioxide, heart rate, stroke severity and sub-type, and comorbidities were collected where available. Data were grouped into 4 time points after AIS: <24 hours, 24 to 72 hours, 4 to 7 days, and >3 months. The modified Rankin Scale assessed functional outcome at 3 months. Modified Rankin Scale was analyzed as both dichotomized (0 to 2 versus 3 to 6) and ordinal (modified Rankin Scale scores, 0-6) outcomes. Univariable and multivariable analyses were conducted to identify significant relationships between dCA parameters, comorbidities, and outcomes, for each time point using generalized linear (dichotomized outcome), or cumulative link (ordinal outcome) mixed models. The participating center was modeled as a random intercept to generate odds ratios with 95% CIs. RESULTS The sample included 384 individuals (35% women) from 7 centers, aged 66.3±13.7 years, with predominantly nonlacunar stroke (n=348, 69%). In the affected hemisphere, higher phase at very low-frequency predicted better outcome (dichotomized modified Rankin Scale) at <24 (crude odds ratios, 2.17 [95% CI, 1.47-3.19]; P<0.001) hours, 24-72 (crude odds ratios, 1.95 [95% CI, 1.21-3.13]; P=0.006) hours, and phase at low-frequency predicted outcome at 3 (crude odds ratios, 3.03 [95% CI, 1.10-8.33]; P=0.032) months. These results remained after covariate adjustment. CONCLUSIONS Greater transfer function analysis-derived phase was associated with improved functional outcome at 3 months after AIS. dCA parameters in the early phase of AIS may help to predict functional outcome.

Clinical outcomes of anatomic vs. reverse total shoulder arthroplasty in primary osteoarthritis with preoperative external rotation weakness and an intact rotator cuff: a case-control study. J Shoulder Elbow Surg 2024; 33:e185-e197. [PMID: 37660887 DOI: 10.1016/j.jse.2023.07.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 07/21/2023] [Accepted: 07/29/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND Anatomic (aTSA) and reverse total shoulder arthroplasty (rTSA) are well-established treatments for patients with primary osteoarthritis and an intact cuff. However, it is unclear whether aTSA or rTSA provides superior outcomes in patients with preoperative external rotation (ER) weakness. METHODS A retrospective review of a prospectively collected shoulder arthroplasty database was performed between 2007 and 2020. Patients were excluded for preoperative diagnoses of nerve injury, infection, tumor, or fracture. The analysis included 333 aTSAs and 155 rTSAs performed for primary cuff-intact osteoarthritis with 2-year minimum follow-up. Defining preoperative ER weakness as strength <3.3 kilograms (7.2 pounds), 3 cohorts were created and matched: (1) weak aTSAs (n = 74) vs. normal aTSAs (n = 74), (2) weak rTSAs (n = 38) vs. normal rTSAs (n = 38), and (3) weak rTSAs (n = 60) vs. weak aTSAs (n = 60). We compared range of motion, outcome scores, strength, complications, and revision rates at the latest follow-up. RESULTS Despite weak aTSAs having poorer preoperative strength in forward elevation and ER (P < .001), neither of these deficits persisted postoperatively compared with the normal cohort. Likewise, weak rTSAs had poorer preoperative strength in forward elevation and ER, overhead motion, and Constant, Shoulder Pain and Disability Index, and University of California, Los Angeles scores (P < .029). However, no statistically significant differences were found between preoperatively weak and normal rTSAs. When comparing weak aTSA vs. weak rTSA, no differences were found in preoperative and postoperative outcomes, proportion of patients achieving the minimal clinically important difference and substantial clinical benefit, and complication and rate of revision surgery. CONCLUSIONS In preoperatively weak patients with cuff-intact primary osteoarthritis, aTSA leads to similar postoperative strength, range of motion, and outcome scores compared with patients with normal preoperative strength, indicating that preoperative weakness does not preclude aTSA use. Furthermore, patients who were preoperatively weak in ER demonstrated improved postoperative rotational motion after undergoing aTSA and rTSA, with both groups achieving the minimal clinically important difference and substantial clinical benefit at similar rates.

Does achieving clinically important thresholds after first shoulder arthroplasty predict similar outcomes of the contralateral shoulder? J Shoulder Elbow Surg 2024; 33:880-887. [PMID: 37690587 DOI: 10.1016/j.jse.2023.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 07/30/2023] [Accepted: 08/06/2023] [Indexed: 09/12/2023]
Abstract
BACKGROUND Patients are increasingly undergoing bilateral total shoulder arthroplasty (TSA). At present, it is unknown whether success after the first TSA is predictive of success after contralateral TSA. We aimed to determine whether exceeding clinically important thresholds of success after primary TSA predicts similar outcomes for subsequent contralateral TSA. METHODS We performed a retrospective review of a prospectively collected shoulder arthroplasty database for patients undergoing bilateral primary anatomic (aTSA) or reverse (rTSA) total shoulder arthroplasty since January 2000 with preoperative and 2- or 3-year clinical follow-up. Our primary outcome was whether exceeding clinically important thresholds in the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score for the first TSA was predictive of similar success of the contralateral TSA; thresholds for the ASES score were adopted from prior literature and included the minimal clinically important difference (MCID), the substantial clinical benefit (SCB), 30% of maximal possible improvement (MPI), and the patient acceptable symptomatic state (PASS). The PASS is defined as the highest level of symptom beyond which patients consider themselves well, which may be a better indicator of a patient's quality of life. To determine whether exceeding clinically important thresholds was independently predictive of similar success after second contralateral TSA, we performed multivariable logistic regression adjusted for age at second surgery, sex, BMI, and type of first and second TSA. RESULTS Of the 134 patients identified that underwent bilateral shoulder arthroplasty, 65 (49%) had bilateral rTSAs, 45 (34%) had bilateral aTSAs, 21 (16%) underwent aTSA/rTSA, and 3 (2%) underwent rTSA/aTSA. On multivariable logistic regression, exceeding clinically important thresholds after first TSA was not associated with greater odds of achieving thresholds after second TSA when success was evaluated by the MCID, SCB, and 30% MPI. In contrast, exceeding the PASS after first TSA was associated with 5.9 times greater odds (95% confidence interval 2.5-14.4, P < .001) of exceeding the PASS after second TSA. Overall, patients who exceeded the PASS after first TSA exceeded the PASS after second TSA at a higher rate (71% vs. 29%, P < .001); this difference persisted when stratified by type of prosthesis for first and second TSA. CONCLUSIONS Patients who achieve the ASES score PASS after first TSA have greater odds of achieving the PASS for the contralateral shoulder regardless of prostheses type.

Anatomic versus reverse total shoulder arthroplasty outcomes after prior contralateral anatomic total shoulder arthroplasty in patients with bilateral primary osteoarthritis with an intact rotator cuff. INTERNATIONAL ORTHOPAEDICS 2024; 48:801-807. [PMID: 38032497 DOI: 10.1007/s00264-023-06044-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Accepted: 11/12/2023] [Indexed: 12/01/2023]
Abstract
PURPOSE We aimed to compare outcomes in patients that underwent bilateral anatomic total shoulder arthroplasty (aTSA) vs. aTSA/ reverse total shoulder arthroplasty (rTSA) for rotator cuff-intact glenohumeral osteoarthritis (RCI-GHOA) to further elucidate the role of rTSA in this patient population. METHODS A single-institution prospectively collected shoulder arthroplasty database was reviewed for patients undergoing bilateral total shoulder arthroplasty (TSA) for RCI-GHOA with a primary aTSA and subsequent contralateral aTSA or rTSA. Outcome scores (SPADI, SST, ASES, UCLA, Constant) and active range of motion (abduction, forward elevation [FE], external and internal rotation [ER and IR]) were evaluated. Clinically relevant benchmarks (minimal clinically important difference [MCID], substantial clinical benefit [SCB], and patient acceptable symptomatic state [PASS]) were evaluated against values in prior literature. Incidence of surgical complications and revision rates were examined in qualifying patients as well as those without RESULTS Of the 55 bilateral TSA patients with an intact rotator cuff, 46 underwent aTSA/aTSA and 9 underwent aTSA/rTSA. At the time of the second TSA, patients undergoing aTSA/rTSA were older (71 ± 4 vs. 67 ± 7, P = .032) and more commonly had inflammatory arthritis (44% vs. 11%, P = .031). Mean time to the second TSA was shorter for aTSA/aTSA (2.3 ± 2.8 vs. 4.4 ± 3.6 years, P < .001). Postoperative outcomes were similar after the first aTSAs between groups with similar proportions achieving the MCID, SCB, and PASS (all P > .05). The 2nd TSAs between groups were similar preoperatively, but aTSA/rTSA had superior outcome scores, overhead motion, and active abduction compared to patients that underwent aTSA/aTSA. There were no differences in active ER and IR scores or complication rates between groups. CONCLUSION Patients with RCI-GHOA have excellent clinical outcomes after either aTSA/aTSA or aTSA/rTSA.

Does hydrogen peroxide application to the dermis following surgical incision affect Cutibacterium acnes cultures in total shoulder arthroplasty in male patients? A randomized controlled trial. J Shoulder Elbow Surg 2024; 33:618-627. [PMID: 38072031 DOI: 10.1016/j.jse.2023.10.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 10/16/2023] [Accepted: 10/24/2023] [Indexed: 02/18/2024]
Abstract
BACKGROUND Periprosthetic joint infections occur in 1%-4% of primary total shoulder arthroplasties (TSAs). Cutibacterium acnes is the most commonly implicated organism and has been shown to persist in the dermis despite use of preoperative antibiotics and standard skin preparations. Studies have shown decreased rates of cultures positive for C acnes with use of preoperative benzoyl peroxide or hydrogen peroxide (H2O2), but even with this positive deep cultures remain common. We sought to determine whether an additional application of H2O2 directly to the dermis following skin incision would further decrease deep culture positivity rates. METHODS We performed a randomized controlled trial comparing tissue culture results in primary TSA in patients who received a standard skin preparation with H2O2, ethanol, and ChloraPrep (CareFusion, Leawood, KS, USA) vs. an additional application of H2O2 to the dermis immediately after skin incision. Given the sexual dimorphism seen in the shoulder microbiome regarding C acnes colonization rates, only male patients were included. Bivariable and multivariable analyses were performed to compare rates of positive cultures based on demographic and surgical factors. RESULTS Dermal cultures were found to be positive for C acnes at similar rates between the experimental and control cohorts for the initial (22% vs. 28%, P = .600) and final (61% vs. 50%, P > .999) dermal swabs. On bivariable analysis, the rate of positive deep cultures for C acnes was lower in the experimental group, but this difference was not statistically significant (28% vs. 44%, P = .130). However, patients who underwent anatomic TSA were found to have a significantly greater rate of deep cultures positive for C acnes (57% vs. 28%, P = .048); when controlling for this on multivariable analysis, the experimental cohort was found to be associated with significantly lower odds of having positive deep cultures (odds ratio, 0.37 [95% confidence interval, 0.16-0.90], P = .023). There were no wound complications in either cohort. CONCLUSIONS An additional H2O2 application directly to the dermis following skin incision resulted in a small but statistically significant decrease in the odds of having deep cultures positive for C acnes without any obvious adverse effects on wound healing. Given its cost-effectiveness, use of a post-incisional dermal decontamination protocol may be considered as an adjuvant to preoperative use of benzoyl peroxide or H2O2 to decrease C acnes contamination.

Abstract
BACKGROUND Urologic chronic pelvic pain syndrome (UCPPS), which includes interstitial cystitis/bladder pain syndrome (IC/BPS) and chronic prostatitis (CP/CPPS), is associated with increased voiding frequency, nocturia, and chronic pelvic pain. The cause of these diseases is unknown and likely involves many different mechanisms. Dysregulated renin-angiotensin-aldosterone-system (RAAS) signaling is a potential pathologic mechanism for IC/BPS and CP/CPPS. Many angiotensin receptor downstream signaling factors, including oxidative stress, fibrosis, mast cell recruitment, and increased inflammatory mediators, are present in the bladders of IC/BPS patients and prostates of CP/CPPS patients. Therefore, we aimed to test the hypothesis that UCPPS patients have dysregulated angiotensin signaling, resulting in increased hypertension compared to controls. Secondly, we evaluated symptom severity in patients with and without hypertension and antihypertensive medication use. METHODS Data from UCPPS patients (n = 424), fibromyalgia or irritable bowel syndrome (positive controls, n = 200), and healthy controls (n = 415) were obtained from the NIDDK Multidisciplinary Approach to the Study of Chronic Pelvic Pain I (MAPP-I). Diagnosis of hypertension, current antihypertensive medications, pain severity, and urinary symptom severity were analyzed using chi-square test and t-test. RESULTS The combination of diagnosis and antihypertensive medications use was highest in the UCPPS group (n = 74, 18%), followed by positive (n = 34, 17%) and healthy controls (n = 48, 12%, p = 0.04). There were no differences in symptom severity based on hypertension in UCPPS and CP/CPPS; however, IC/BPS had worse ICSI (p = 0.031), AUA-SI (p = 0.04), and BPI pain severity (0.02). Patients (n = 7) with a hypertension diagnosis not on antihypertensive medications reported the greatest severity of pain and urinary symptoms. CONCLUSION This pattern of findings suggests that there may be a relationship between hypertension and UCPPS. Treating hypertension among these patients may result in reduced pain and symptom severity. Further investigation on the relationship between hypertension, antihypertensive medication use, and UCPPS and the role of angiotensin signaling in UCPPS conditions is needed.

Abstract
INTRODUCTION Investigator-initiated research trial failure is a national concern that hinders the dissemination of information while wasting resources, time, and funding. The goal of this analysis was to provide an objective review of points to consider increasing an investigator's chances of success. METHODS The included trials were divided into two groups based on whether they were successful or unsuccessful in meeting enrollment goals. Common issues were noted for each trial to identify prevalent issues and compare their quantity within each group. RESULTS Unsuccessful trials averaged twice as many issues as trials in the successful group. The most common problems identified in unsuccessful studies involved study planning, whereas the most common problems identified in successful studies revolved around study staff. CONCLUSIONS There is no single definitive indicator for trial failure; however, awareness of these issues in a trial's planning phase can help prevent their occurrence and aid in overall completion and publication.

Presence of endometriosis and chronic overlapping pain conditions negatively impacts the pain experience in women with chronic pelvic-abdominal pain: A cross-sectional survey. WOMEN'S HEALTH (LONDON, ENGLAND) 2024; 20:17455057241248017. [PMID: 38682290 PMCID: PMC11057341 DOI: 10.1177/17455057241248017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 02/06/2024] [Accepted: 04/02/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Evidence of overlap between endometriosis and chronic pain conditions is emerging; however, little is known about how the pain experience differs based on the presence or absence of endometriosis. OBJECTIVES In a sample of women reporting chronic pelvic-abdominal pain (CPP), the aim of this study was to characterize differences in pain symptomatology between women with and without endometriosis and to examine the influence of chronic overlapping pain conditions (COPCs) on pain among these two groups. DESIGN This was a cross-sectional study, based on an online survey. METHODS Participants (aged 18+ years) completed a survey collecting pain diagnoses and symptoms assessing pelvic pain severity, pain interference, and pain impact. Independent sample t-tests, chi-square, and multiple linear regression models were employed to analyze group differences in pain symptomatology and COPCs. RESULTS Of the 525 respondents with CPP, 25% (n = 133) reported having endometriosis. Women with endometriosis were younger at the onset of pelvic pain, relative to women without endometriosis (p = 0.04). There were no differences in age, race, ethnicity, or duration of pelvic pain between women with and without endometriosis. Women with endometriosis reported higher pelvic pain severity (+0.8, 95% CI = 0.4-1.1), pain interference (+5.9, 95% CI = 2.4-9.3), and pain impact (+1.9, 95% CI = 0.8-2.9). Endometriosis was associated with a higher number of COPCs (p = 0.003), with 25% (n = 33) of women reporting ⩾3 overlapping pain conditions compared with 12% (n = 45) of those without endometriosis. Women with endometriosis had a higher frequency of fibromyalgia (p < 0.001), chronic fatigue syndrome (p < 0.001), and temporomandibular disorder (p = 0.001). The number of COPCs was associated with higher pain severity, interference, and impact, independently of endometriosis. CONCLUSION Women with endometriosis experienced higher levels of pain-related burden and COPCs compared with those without endometriosis. Pain intensity, interference, and impact increased with a higher number of pain conditions regardless of endometriosis presence.

Clinical outcomes of anatomical versus reverse total shoulder arthroplasty in patients with primary osteoarthritis, an intact rotator cuff, and limited forward elevation. Bone Joint J 2023; 105-B:1303-1313.

Abstract
Aims Both anatomical and reverse total shoulder arthroplasty (aTSA and rTSA) provide functional improvements. A reported benefit of aTSA is better range of motion (ROM). However, it is not clear which procedure provides better outcomes in patients with limited foward elevation (FE). The aim of this study was to compare the outcome of aTSA and rTSA in patients with glenohumeral osteoarthritis (OA), an intact rotator cuff, and limited FE. Methods This was a retrospective review of a single institution's prospectively collected shoulder arthroplasty database for TSAs undertaken between 2007 and 2020. A total of 344 aTSAs and 163 rTSAs, which were performed in patients with OA and an intact rotator cuff with a minimum follow-up of two years, were included. Using the definition of preoperative stiffness as passive FE ≤ 105°, three cohorts were matched 1:1 by age, sex, and follow-up: stiff aTSAs (85) to non-stiff aTSAs (85); stiff rTSAs (74) to non-stiff rTSAs (74); and stiff rTSAs (64) to stiff aTSAs (64). We the compared ROMs, outcome scores, and complication and revision rates. Results Compared with non-stiff aTSAs, stiff aTSAs had poorer passive FE and active external rotation (ER), whereas there were no significant postoperative differences between stiff rTSAs and non-stiff rTSAs. There were no significant differences in preoperative function when comparing stiff aTSAs with stiff rTSAs. However, stiff rTSAs had significantly greater postoperative active and passive FE (p = 0.001 and 0.004, respectively), and active abduction (p = 0.001) compared with stiff aTSAs. The outcome scores were significantly more favourable in stiff rTSAs for the Shoulder Pain and Disability Index, Simple Shoulder Test, American Shoulder and Elbow Surgeons score, University of California, Los Angeles score, and the Constant score, compared with stiff aTSAs. When comparing the proportion of stiff aTSAs versus stiff rTSAs that exceeded the minimal clinically important difference and substantial clinical benefit, stiff rTSAs achieved both at greater rates for all measurements except active ER. The complication rate did not significantly differ between stiff aTSAs and stiff rTSAs, but there was a significantly higher rate of revision surgery in stiff aTSAs (p = 0.007). Conclusion Postoperative overhead ROM, outcome scores, and rates of revision surgery favour the use of a rTSA rather than aTSA in patients with glenohumeral OA, an intact rotator cuff and limited FE, with similar rotational ROM in these two groups.

Academic productivity and NIH funding for anesthesiology departmental chairs: A 15-year comparison. J Clin Anesth 2023; 91:111240. [PMID: 37660512 DOI: 10.1016/j.jclinane.2023.111240] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 07/28/2023] [Accepted: 08/23/2023] [Indexed: 09/05/2023]
Abstract
STUDY OBJECTIVE This study evaluated whether there were improvements in the number of departmental National Institutes of Health (NIH) training grants and the academic productivity of departmental chairs in terms of NIH research funding and PubMed-cited publications when compared to chairs of the same departments in 2006. DESIGN Each chair was identified from the Society of Academic Associations of Academic Anesthesiology & Perioperative Medicine's Association of Academic Anesthesiology Chairs and entered into the NIH Research Portfolio Online Reporting Tools (RePORTER), PubMed, SCOPUS, and the National Provider Identifier Registry. MEASUREMENTS The number and funding amounts of training grants awarded to the department in 2010, 2015, and 2020 were obtained as well as the department's national ranking and total dollar amount for NIH funding in 2020. For the current chair cohort, total publications and m-quotient (h-index corrected for active research years) were recorded along with each chair's history of NIH grant funding. These data were compared to a previous study of anesthesiology chairs that reviewed funding and publications through 2006. MAIN RESULTS We analyzed data from 100 academic departments of anesthesiology and compared their scholarly activity relative to data gathered in 2006. In 2020, 52 of 100 departments of anesthesiology had evidence of NIH funding. There were not statistically significant (P > 0.05) differences in grants funding obtained by chairs between 2006 and 2020 with the exception that more chairs in 2006 had program or center grants. Median publications for chairs significantly increased from 35 in 2006 to 55 in 2021 (IRR = 1.5, 95% CI = 1.2-2.0, P = 0.003). Nineteen percent of chairs were female, which did not significantly differ from the proportion of women in the 2006 paper (15%, χ2 = 0.57, df = 1, P = 0.452). Of the male chairs, 90% were professors whereas 63% of female chairs were professors (χ2 = 8.8, df = 1, P = 0.003). Female chairs had fewer publications than male chairs (IRR = 1.8, 95% CI = 1.2-1.8, P = 0.002); however, m-quotients were not significantly different between men and women (P = 0.602). CONCLUSIONS When compared to 2006, department of anesthesiology chairs had more publications in 2021; however, NIH funding rates remained unchanged. The specialty had 19% female chairs, and those chairs had fewer publications than their male counterparts, though sex differences were attenuated using metrics that account for disparities in career length.

The Kumar Technique: A Novel and Effective Approach to Transforaminal Epidural Steroid Injections. Cureus 2023; 15:e47210. [PMID: 38022188 PMCID: PMC10653120 DOI: 10.7759/cureus.47210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/17/2023] [Indexed: 12/01/2023] Open
Abstract
Background Transforaminal epidural steroid injections (TFESIs) are widely used as a minimally invasive treatment for lumbar radicular pain. This study presents an alternative approach for lumbar TFESI, the Kumar Technique, which utilizes a more lateral and inferior needle starting point to better align the trajectory of the needle with the neural foramen. We hypothesize the Kumar Technique will result in safer and more effective outcomes than the traditional approach to TFESI. This article was previously presented as a poster at the 2023 University of Florida College of Medicine Celebration of Research on February 27-28, 2023, and as an abstract and poster at the 2023 University of Florida Department of Anesthesiology Celebration of Research on March 29, 2023. Methods The charts for 1,424 patients who received lumbar TFESIs were retrospectively reviewed, and patients were stratified into groups receiving either the traditional approach or the Kumar Technique. Outcomes measures included numerical pain scores, measures of functional status and activity limitations, duration of pain relief, and procedural complications. Results Compared to the group undergoing the traditional approach, patients receiving the Kumar Technique reported a significantly greater decrease in average pain (-2.3 (95% CI: -3.0 to -1.6) vs -1.1 (95% CI: -1.4 to -0.7)) and maximum pain (-2.4 (95% CI: -3.2 to -1.6) vs -1.3 (95% CI: -1.8 to -0.9)). Patients receiving the Kumar Technique had a significantly greater likelihood of reporting any pain relief (OR: 2.10, 95% CI:1.59 to 2.79) compared to those undergoing the traditional approach. In addition, a greater percentage of patients receiving the Kumar Technique experienced at least one month of pain relief compared to the traditional approach (54% vs 40%; z = 3.85, p < 0.001). The occurrence of complications did not significantly vary between the modified (4.1%) and the traditional (3.0%) approaches. Conclusions The Kumar Technique is a modified TFESI approach that allows for improved access to the nerve roots through a more lateral and inferior needle entry point. The analysis supports the benefits of the Kumar Technique with patients experiencing a greater reduction in pain and longer durations of pain relief without increasing the risk of complications.

Abstract
BACKGROUND Lumbar facet arthropathy is one of the leading causes of back pain. Lumbar radiofrequency lesioning is a therapy for lumbar facet arthropathy that uses heat to ablate the transmission of nerve signals from the medial branches of the spinal nerves associated with the corresponding painful lumbar joints. OBJECTIVES The present investigation evaluated the outcomes of patients undergoing lumbar radiofrequency ablation at an academic pain program with a special focus on the influence of gender and obesity. STUDY DESIGN Retrospective chart review. SETTING Academic tertiary care center. METHODS We reviewed the charts of 232 patients for age, body mass index, gender, other procedures, and complications, in addition to the primary outcome measurements of Visual Analog Scale pain scores, pain relief percentages, pain relief duration, and functional status improvement per patient report. Associations with outcomes were evaluated with correlations, t tests/analysis of variance, and c2 test. Influences on a change in Visual Analog Scale pain scores before and after treatment were assessed with linear regression. RESULTS Patients had an average pain reduction of 76.6% (SD = 24.5) from the initial treatment and an average of 30.7 weeks (SD = 21.2) of pain relief from the initial treatment. A total of 83% of the patients reported an improvement in functional status from the initial treatment. Women (mean = 79.8%, SD = 21.4) had a slightly higher pain relief percentage than men (mean = 71.6%, SD = 28.1; P = 0.046). A higher body mass index was associated with less improvement in Visual Analog Scale maximum pain scores from before and after the procedure (b = 0.04; SE = 0.02; P = 0.042). LIMITATIONS Our study is not a randomized controlled trial; however, based on the number of patients reviewed, our data provide important information regarding lumbar radiofrequency ablations. CONCLUSIONS This study highlights significant effectiveness for patients undergoing lumbar radiofrequency ablations for lumbar facet joint pain. A variation in effectiveness appears to be influenced by gender and obesity, and therefore additional studies are warranted to further investigate these differences.

Preoperative respiratory strength training is feasible and safe and improves pulmonary physiologic capacity in individuals undergoing cardiovascular surgery. JTCVS OPEN 2023; 15:324-331. [PMID: 37808054 PMCID: PMC10556933 DOI: 10.1016/j.xjon.2023.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 07/06/2023] [Accepted: 07/13/2023] [Indexed: 10/10/2023]
Abstract
Objective To determine the safety, feasibility, and physiologic impact of a preoperative respiratory strength training (RST) program in individuals undergoing elective cardiac surgery (CS). Methods Twenty-five adults undergoing an elective CS at an academic hospital setting enrolled and completed RST 5 days/week (50 repetitions, 50% training load, ≥3 weeks) at home via telehealth in this open-label prospective cohort study. RST adherence, telehealth attendance, and adverse events were tracked. Pre- and post-RST outcomes of maximum expiratory pressure (MEP), maximum inspiratory pressure (MIP), voluntary cough spirometry, and patient-reported dyspnea were collected. Descriptive analyses and Wilcoxon signed rank-tests were performed. Results Two participants (9%) did not complete the prescribed RST program. No significant RST-related adverse events occurred. Treatment adherence for all enrolled participants was 90%, and telehealth attendance was 99%. Of the CS patients who completed the prescribed program (n = 23; 91%), treatment adherence and telehealth attendance were excellent (98% and 100%, respectively). Significant increases in primary outcomes were observed: MEP mean change, +15.4 (95% confidence interval [CI], +3.4 to +27.3, P < .007); MIP mean change, +14.9 (95% CI, +9.4 to +20.4, P < .0001). No statistically significant differences in voluntary cough or perceived dyspnea outcomes were observed (P > .05). Conclusions These preliminary data demonstrate that a preoperative RST program is safe and feasible and can improve short-term respiratory physiologic capacity (MEP and MIP) in CS patients. Future research is warranted to validate the current findings in a larger cohort of CS patients and to determine whether RST improves postoperative extubation outcomes, airway clearance capacity, and aspiration following cardiac surgery.

Abstract
OBJECTIVE No efficacious treatments exist to improve or prolong bulbar functions of speech and swallowing in persons with amyotrophic lateral sclerosis (pALS). This study evaluated the short-term impact of dextromethorphan/quinidine (DMQ) treatment on speech and swallowing function in pALS. METHODS This was a cohort trial conducted between August 2019 to August 2021 in pALS with a confirmed diagnosis of probable-definite ALS (El-Escorial Criteria-revisited) and bulbar impairment (ALS Functional Rating Scale score ≤ 10 and speaking rate ≤ 140 words per minute) who were DMQ naïve. Efficacy of DMQ was assessed via pre-post change in the ALS Functional Rating Scale-Revised bulbar subscale and validated speech and swallowing outcomes. Paired t-tests, Fisher's exact, and χ2 tests were conducted with alpha at 0.05. RESULTS Twenty-eight pALS enrolled, and 24 participants completed the 28-day trial of DMQ. A significant increase in ALSFRS-R bulbar subscale score pre- (7.47 ± 1.98) to post- (8.39 ± 1.79) treatment was observed (mean difference: 0.92, 95% CI: 0.46-1.36, p < 0.001). Functional swallowing outcomes improved, with a reduction in unsafe (75% vs. 44%, p = 0.003) and inefficient swallowing (67% vs. 58%, p = 0.002); the relative speech event duration in a standard reading passage increased, indicating a greater duration of uninterrupted speech (mean difference: 0.33 s, 95% CI: 0.02-0.65, p = 0.035). No differences in diadochokinetic rate or speech intelligibility were observed (p > 0.05). INTERPRETATION Results of this study provide preliminary evidence that DMQ pharmacologic intervention may have the potential to improve or maintain bulbar function in pALS.

Maximum Phonation Time as a Surrogate Marker for Airway Clearance Physiologic Capacity and Pulmonary Function in Individuals With Amyotrophic Lateral Sclerosis. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2023; 66:1165-1172. [PMID: 36877985 PMCID: PMC10187964 DOI: 10.1044/2022_jslhr-22-00522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 11/23/2022] [Accepted: 12/12/2022] [Indexed: 05/18/2023]
Abstract
PURPOSE The increased use of telehealth practices has created a critical need for home-based surrogate markers for prognostic respiratory indicators of disease progression in persons with amyotrophic lateral sclerosis (pALS). Given that phonation relies on the respiratory subsystem of speech production, we aimed to examine the relationships between maximum phonation time (MPT), forced vital capacity, and peak cough flow and to determine the discriminant ability of MPT to detect forced vital capacity and peak cough flow impairments in pALS. METHOD MPT, peak cough flow, forced vital capacity, and ALS Functional Rating Scale scores were obtained from 62 pALS (El-Escorial Revised) every 3 months as part of a longitudinal natural history study. Pearson's correlations, linear regressions, and receiver operator characteristic curve analyses with the area under the curve (AUC), sensitivity, specificity, and likelihood ratios were calculated. RESULTS The mean age of pALS was 63.14 ± 10.95 years, 49% were female, and 43% had bulbar onset. MPT predicted forced vital capacity, F(1, 225) = 117.96, p < .0001, and peak cough flow, F(1, 217) = 98.79, p < .0001. A significant interaction was noted between MPT and ALS Functional Rating Scale-Revised respiratory subscore for forced vital capacity, F(1, 222) = 6.7, p = .010, and peak cough flow, F(1, 215) = 4.37, p = .034. The discriminant ability of MPT was excellent for peak cough flow (AUC = 0.88) and acceptable for forced vital capacity (AUC = 0.78). CONCLUSIONS MPT is a simple clinical test that can be measured via telehealth and represents a potential surrogate marker for important respiratory and airway clearance indices. Further larger studies are required to validate these findings with remote data collection. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.22186408.

Abstract
BACKGROUND The authors tested the hypothesis that the effects of traumatic brain injury, surgery, and sevoflurane interact to induce neurobehavioral abnormalities in adult male rats and in their offspring (an animal model of intergenerational perioperative neurocognitive disorder). METHODS Sprague-Dawley male rats (assigned generation F0) underwent a traumatic brain injury on postnatal day 60 that involved craniectomy (surgery) under 3% sevoflurane for 40 min followed by 2.1% sevoflurane for 3 h on postnatal days 62, 64, and 66 (injury group). The surgery group had craniectomy without traumatic brain injury, whereas the sevoflurane group had sevoflurane only. On postnatal day 90, F0 males and control females were mated to generate offspring (assigned generation F1). RESULTS Acutely, F0 injury rats exhibited the greatest increases in serum corticosterone and interleukin-1β and -6, and activation of the hippocampal microglia. Long-term, compared to controls, F0 injury rats had the most exacerbated corticosterone levels at rest (mean ± SD, 2.21 ± 0.64 vs. 7.28 ± 1.95 ng/ml, n = 7 - 8; P < 0.001) and 10 min after restraint (133.12 ± 33.98 vs. 232.83 ± 40.71 ng/ml, n = 7 - 8; P < 0.001), increased interleukin-1β and -6, and reduced expression of hippocampal glucocorticoid receptor (Nr3c1; 0.53 ± 0.08 fold change relative to control, P < 0.001, n = 6) and brain-derived neurotrophic factor genes. They also exhibited greater behavioral deficiencies. Similar abnormalities were evident in their male offspring, whereas F1 females were not affected. The reduced Nr3c1 expression in F1 male, but not female, hippocampus was accompanied by corresponding Nr3c1 promoter hypermethylated CpG sites in F0 spermatozoa and F1 male, but not female, hippocampus. CONCLUSIONS These findings in rats suggest that young adult males with traumatic brain injury are at an increased risk of developing perioperative neurocognitive disorder, as are their unexposed male but not female offspring.

Predictors of Peak Expiratory Cough Flow in Individuals with Amyotrophic Lateral Sclerosis. Dysphagia 2023; 38:719-725.

Abstract
Dystussia is prevalent in individuals with amyotrophic lateral sclerosis (ALS), leading to a diminished physiologic capacity to effectively defend the airway. We aimed to identify predictors of peak expiratory cough flow rate in individuals with ALS. One hundred and thirty-four individuals with a confirmed diagnosis of ALS (El-Escorial criteria revised) completed the ALS Functional Rating Scale-Revised (ALSFRS-R) and underwent pulmonary function and cough spirometry testing. Pearson's correlation coefficients and hierarchical multiple regression modeling were conducted to determine predictors of voluntary cough peak expiratory flow rate (p < 0.05). The full model including age, bulbar disease, cough spirometry metrics, and respiratory parameters had a marginal R2 = 0.635, F (7, 126) = 30.241, p < 0.0005, adjusted R2 = 0.61. Maximum expiratory pressure, compression phase, and vital capacity did not contribute and were therefore removed (p < 0.05). The most parsimonious predictive model included age, bulbar disease, peak inspiratory flow rate and duration, peak expiratory rise time, and inspiratory pressure generation with a marginal R2 = 0.543. Although expiratory pressure generation has historically served as the therapeutic target to improve dystussia in ALS, the current dataset highlighted that the inability to quickly and forcefully inspire during the inspiratory phase of voluntary cough places patients at a mechanical disadvantage to generate subsequent high-velocity expiratory airflow to clear the airway. Thus, therapeutic training programs that include both inspiratory and expiratory strength targets may optimize airway clearance capacity in this challenging patient population.

Abstract
INTRODUCTION Sleep disturbances are associated with pain and mental health. We prospectively compared a cohort of patients with orthopaedic trauma with a control group to establish the prevalence and duration of sleep disturbance and associations between sleep disturbance and pain, mood scores, and functional outcome scores. METHODS Subjects were patients with orthopaedic trauma undergoing in-patient surgical procedures and healthy control subjects from the community. Questionnaires completed by all subjects included the VAS numerical pain rating scale, the abbreviated profile of mood states, Patient-Reported Outcomes Measurement Information System Physical Function, and Patient-Reported Outcomes Measurement Information System Sleep Disturbance. Control subjects completed the surveys once, and subjects with trauma completed them at 2, 6, and 24 weeks postoperatively. RESULTS Healthy control subjects (28.6 ± 13.2) were significantly younger than patients with trauma (41.8 ± 18.9) ( P < 0.001). Compared with control subjects, at 2-week follow-up visit, patients with trauma had worse sleep ( P < 0.001) and worse mood ( P = 0.006). Across the study period, patients with trauma showed improvements in physical function ( P < 0.001) and pain (at rest [ P = 0.02], during activity [ P = 0.02], and at night [ P = 0.002]). In patients with trauma, better sleep disturbance scores were associated with better mood and less pain for all pain metrics ( P < 0.001). DISCUSSION Patients with orthopaedic trauma have worse sleep disturbance scores at 2 weeks postoperatively compared with normal control subjects; this difference attenuated at 6 weeks. Sleep disturbance was found to markedly correlate with pain and mood, with worse sleep quality associated with higher pain and worse mood. Improvement in sleep quality across 24 weeks postoperatively was associated with improvement in mood scores. CONCLUSION Patients should be counseled about the likely development of sleep disturbance and the possible association with worse emotional/mental health with worse sleep. Physicians should consider incorporating a multidisciplinary approach to the management of these select patients.

A prospective examination of swallow and cough dysfunction after lung transplantation. Neurogastroenterol Motil 2023; 35:e14458. [PMID: 36168190 DOI: 10.1111/nmo.14458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 08/08/2022] [Accepted: 08/23/2022] [Indexed: 02/08/2023]
Abstract
OBJECTIVES Swallow and cough dysfunction are possible surgical complications of lung transplantation (LT). We examined voluntary cough strength, sensorimotor reflexive cough integrity, and swallow-related respiratory rate (RR) across swallowing safety and aspiration response groups in recovering LT recipients. METHODS Forty-five LT recipients underwent flexible endoscopic evaluation of swallowing indexed by the validated Penetration Aspiration Scale. RR before and after a 3-ounce water drinking task was measured. Voluntary and reflexive cough screening were performed to index motor and sensory outcomes. T-tests, one-way ANOVAs, and chi-square (odds ratios) were used. RESULTS 60% of patients exhibited laryngeal penetration (n = 27) and 40% demonstrated tracheal aspiration (n = 18); 72% (n = 13) demonstrated silent aspiration. Baseline RR was higher in aspirators versus non-aspirators (26.5 vs. 22.6, p = 0.04) and in silent aspirators compared to non-silent aspirators (27.9 vs. 20.7, p = 0.01). RR change post-swallowing did not differ between aspiration response groups; however, it was significantly higher in aspirators compared to non-aspirators (3 vs. -2, p = 0.02). Compared to non-silent aspirators, silent aspirators demonstrated reduced voluntary cough peak expiratory flow (PEF; 166 vs. 324 L/min, p = 0.01). PEF, motor and urge to cough reflex cough ratings did not differ between aspirators and non-aspirators. Silent aspirators demonstrated a 7.5 times higher odds of failing reflex cough screening compared to non-silent aspirators (p = 0.07). CONCLUSIONS During the acute recovery period, all LT participants demonstrated some degree of unsafe swallowing and reduced voluntary cough strength. Silent aspirators exhibited elevated RR, reduced voluntary cough physiologic capacity to defend the airway, and a clinically distinguishable blunted motor response to reflex cough screening.

Respiratory Strength Training in Amyotrophic Lateral Sclerosis: A Double-Blind, Randomized, Multicenter, Sham-Controlled Trial. Neurology 2023; 100:e1634-e1642. [PMID: 36805435 PMCID: PMC10103108 DOI: 10.1212/wnl.0000000000206830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 12/05/2022] [Indexed: 02/22/2023] Open
Abstract
OBJECTIVE Evaluate the short-term physiologic and one-year functional impact of a 12-week inspiratory and expiratory respiratory strength training (RST) program in individuals with amyotrophic lateral sclerosis (ALS). METHODS A double-blind, randomized, sham-controlled trial was conducted in 45individuals with early-stage ALS. Participants were randomized into 12-weeks of active-RST (30% load, n=23) or sham-RST (0% load, n=22). An intent-to-treat analysis was conducted. Linear regression of pre-post change with group status and pre-test scores as predictors was conducted. Primary outcomes included maximum expiratory and inspiratory pressure (MEP, MIP) and secondary outcomes were cough spirometry and forced vital capacity. Exploratory follow-up outcomes included one-year global and bulbar decline (ALS Functional Rating Scale-Revised- ALSFRS-R total and Bulbar subscale slope), oral-intake status, and time to noninvasive ventilation (NIV). RESULTS RST completion rate was 91% with no RST-related adverse events. A 12-week RST program led to increases in MEP (p=0.004) but not MIP (p=0.33). On average, MEP increased by 20.8 cmH20 following active-RST (95% CI: +7.6, +33.9) and decreased by 1.0 cmH20 (95% CI: -9.1, +7.2) following sham-RST. Mean MIP increased by 8.9 cmH20 (95% CI: +1.5, +16.3) and 4.8 cmH20 (95% CI: -0.6, +10.2) for the active and sham groups respectively. Secondary Outcomes: RST led to significant increases in cough peak inspiratory flow (p=0.02), however, did not impact cough expiratory flow (p = 0.06) or FVC (p=0.60). Twelve-Month Outcomes: A significant difference in ALSFRS-R Bulbar subscale slope was observed across treatment groups, with a more than two-fold faster rate of bulbar decline in the sham versus active-RST groups observed (-0.29 vs. -0.12 points/month, p=0.02). Total ALSFRS-R slope, feeding status, and time to NIV did not differ across treatment groups (p >0.05). CONCLUSIONS RST was well tolerated and led to improvements in some, but not all, short- and long-term outcomes. RST represents a proactive rehabilitative intervention that could increase physiologic capacity of specific breathing and airway clearance functions during the early stages of ALS. Further work is needed to determine optimal training intensity, resistance load specifications, and potential long-term functional outcomes.

Qualitative fit test outcomes for N95 filtering facepiece respirators in health care workers. Am J Infect Control 2023; 51:194-198. [PMID: 35659562 DOI: 10.1016/j.ajic.2022.05.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 05/25/2022] [Accepted: 05/26/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND We analyzed the qualitative fit test results of the filtering facepiece respirators (FFRs) used at our institution to determine their performance and utility. METHODS We retrospectively analyzed 12,582 qualitative fit testing results for several FFR models among 8,809 health care workers (HCWs). RESULTS The overall failure rate for HCWs was 15.2%. Nearly one-third (2933/8809, 33.3%) had multiple FFRs fit tested. HCW sex was a statistically significant indicator of fit testing failure (χ2 = 29.9, df = 1, P < .001), with women having a 44% higher likelihood (OR, 1.4; 95% CI: 1.27-1.65) than men. There were statistically significant differences in the failure rate across FFRs (Fig 4, F[5, 12475] = 8.4, P < .001). Fluidshield 46867S had a significantly higher failure rate (49%) than the 3M 1860 (P = .012), 3M 1860S (P < .001), 3M 8210 (P < .001), and Safelife (P < .001) FFRs. CONCLUSIONS There was a large degree of variation in fit testing results for the FFRs tested. Although we were unable to find an FFR that fit more than 95% of the HCWs successfully, we identified poorly functioning FFRs that can help our institution with decision-making and budgeting for acquisition and stocking appropriate FFRs.

Clinical Outcomes of Anatomic Versus Reverse Total Shoulder Arthroplasty in Primary Osteoarthritis with Preoperative Rotational Stiffness and an Intact Rotator Cuff: A Case Control Study. J Shoulder Elbow Surg 2023:S1058-2746(23)00054-X. [PMID: 36737034 DOI: 10.1016/j.jse.2022.12.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 12/28/2022] [Indexed: 02/05/2023]
Abstract
BACKGROUND Reverse total shoulder arthroplasty (rTSA) has begun to challenge the place of anatomic total shoulder arthroplasty (aTSA) as a primary procedure for certain indications. One purported benefit of aTSA is improved postoperative range of motion (ROM) compared to rTSA especially in internal rotation; however, it is unclear whether aTSA can provide patients with significant preoperative stiffness superior ROM compared to rTSA. Our purpose was to compare clinical outcomes of aTSA and rTSA performed in stiff versus non-stiff shoulders for rotator cuff intact (RCI) glenohumeral osteoarthritis (GHOA). METHODS A retrospective review of an international shoulder arthroplasty database identified 1,608 aTSAs and 600 rTSAs performed for RCI GHOA with minimum 2-year follow-up. Defining preoperative stiffness as ≤0° of passive ER, we matched: (1) stiff aTSAs (n=257) 1:3 to non-stiff aTSAs, (2) stiff rTSAs (n=87) 1:3 to non-stiff rTSAs, and (3) stiff rTSAs (n=87) 1:1 to stiff aTSAs. We compared ROM, outcome scores, and the rate of complications and revision surgery at latest follow-up. RESULTS Despite stiff aTSAs having poorer preoperative ROM and functional outcome scores for all measures assessed (P<0.001 for all), only poorer postoperative active abduction (113±27° vs. 128±35°, P<0.001), active ER (39±18° vs. 50±20°, P<0.001), and passive ER (45±17° vs. 56 ± 18°, P<0.001) persisted postoperatively compared to the non-stiff cohort. Similarly, stiff rTSAs had poorer preoperative ROM and functional outcome scores for all measures assessed compared to non-stiff rTSAs (P≤0.044), but only poorer active abduction (108±24° vs. 128±29°, P<0.001), active ER (28±17° vs. 42±17°, P<0.001), and passive ER (36±15° vs. 48±17°, P<0.001) persisted. When comparing stiff rTSAs to matched stiff aTSAs, no significant differences in preoperative ROM or functional outcome scores were found. However, stiff aTSAs had greater postoperative active IR score (4.8±1.5 vs. 4.2±1.7, P=0.022), active ER (40±19° vs. 28±17°, P<0.001), and passive ER (46±18° vs. 36±15°, P=0.001). Postoperative outcome scores were similar across all matched cohort comparisons despite motion differences. The rate of complications and need for revision surgery did not differ between any group comparisons. CONCLUSIONS Patients with RCI GHOA who have preoperative rotational stiffness have poorer postoperative ROM compared with non-stiff patients following both aTSA and rTSA, but similar functional outcome scores. Notably, preoperative limitations in passive ER do not appear to be a limitation to utilizing aTSA. Indeed, patients with limited preoperative ER treated with aTSA had greater postoperative internal and external rotation compared to those treated with rTSA.

Dysphagia after cardiac surgery: Prevalence, risk factors, and associated outcomes. J Thorac Cardiovasc Surg 2023; 165:737-746.e3. [PMID: 33814177 DOI: 10.1016/j.jtcvs.2021.02.087] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 02/17/2021] [Accepted: 02/17/2021] [Indexed: 01/18/2023]
Abstract
OBJECTIVES The study objectives were to determine the prevalence of swallowing impairment in adults after cardiac surgery and examine associated risk factors and health-related outcomes. METHODS A prospective single-center study was conducted in postoperative adult cardiac surgery patients with no history of dysphagia. A standardized fiberoptic endoscopic evaluation of swallowing was performed within 72 hours of extubation. Blinded raters completed validated outcomes of swallowing safety and efficiency. Demographic, surgical, and postoperative health-related outcomes were collected. Univariate and multivariable regression analyses were performed with odds ratios (OR) and 95% confidence intervals (CIs). RESULTS In 182 patients examined, imaging confirmed inefficient swallowing (residue) in 52% of patients and unsafe swallowing in 94% (65% penetrators, 29% aspirators). Silent aspiration was observed in 53% of aspirators, and 32% did not clear aspirate material. Independent risk factors for aspiration included New York Heart Association III and IV (OR, 2.9; CI, 1.2-7.0); reoperation (OR, 2.0; CI, 0.7-5.5); transesophageal echocardiogram images greater than 110 (OR, 2.6; CI, 1.1-6.3); intubation greater than 27 hours (OR, 2.1; CI, 0.8-5.3); and endotracheal tube size 8.0 or greater (OR, 3.1; CI, 1.1-8.6). Patients with 3 or 4 identified risk factors had a 16.4 (CI, 3.2-148.4) and 22.4 (CI, 3.7-244.7) increased odds of aspiration, respectively. Compared with nonaspirators, aspirators waited an additional 85 hours to resume oral intake, incurred $49,372 increased costs, and experienced a 43% longer hospital stay (P < .05). Aspiration was associated with pneumonia (OR, 2.6; CI, 1.1-6.5), reintubation (OR, 5.7; CI, 2.1-14.0), and death (OR, 2.8; CI, 1.2-9.0). CONCLUSIONS Tracheal aspiration was prevalent, covert, and associated with increased morbidity and mortality.

A Physician-led Care Redesign Blunts Predictors of Length of Stay after Total Hip and Knee Arthroplasty. J Surg Orthop Adv 2023; 32:97-101.

Abstract
We questioned to what extent traditional predictors of care team burden (via increased length of stay [LOS] after total joint arthroplasty [TJA]) were able to be mitigated through alteration of the care pathway. The impact on LOS of traditional patient risk factors, as well as encounter variables, were analyzed for a consecutive set of patients undergoing surgery before and after a physician-initiated arthroplasty care pathway redesign. We analyzed the impact of these variables on LOS, discharge disposition, and 90-day readmission; separate analyses were performed pre- and post-redesign for LOS. Several patient factors (Risk Assessment and Prediction Tool, body mass index, age, insurance type, smoking) predicted longer LOS in the pre-redesign cohort; post-redesign, only ambulation on the day of surgery and anticoagulation type were predictive. The redesign also lessened the aggregate impact of the patient-specific risk factors, resulting in reduced variation in LOS. Physician leadership of care pathways can reduce the impact of factors that have portended longer LOS, thereby reducing variability in LOS and costs for disparate patient populations while driving improvements in value-based care indices.

Can fluoxetine mitigate mental health decline in musculoskeletal trauma patients: a pilot single-center randomized clinical trial. Pilot Feasibility Stud 2022; 8:184.

Abstract
Background Musculoskeletal trauma is one of the leading causes of disability in the USA and its negative quality of life impact extends beyond that of physical recovery. More than 50% of victims of musculoskeletal trauma suffer lasting mental health issues and post-traumatic stress disorder (PTSD) symptomology following their injury. These symptoms can develop across all spectrums of patients and are independent predictors of poor outcome. Access to mental health care is limited, expensive, and time intensive, and a large majority of the trauma population do not get to utilize this valuable resource. This leaves the burden of management on the orthopedic team, as they are often the only point of contact for the patient within the medical system. Methods This is a single-center, repeated measures, randomized controlled pilot study including up to 100 orthopedic trauma patients aged between 18 and 85 years of age. Subjects are approached during their index hospitalization and are randomized to one of two pharmaceutical interventions, fluoxetine (also known as Prozac) or calcium, for 9 months. Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that is supported for the treatment of PTSD by the American Psychiatric Association. It is low-cost and has minimal side effects and withdrawal symptoms if stopped suddenly. Calcium is a supplement with minimal side effects that is used in our study for its bone-healing potential. Feasibility will be indexed by recruitment feasibility, randomization feasibility, medical adherence, anti-depressant side effects, and fracture union rate. Subjects will complete physical and mental health surveys at baseline, 2 weeks, 6 weeks, 3 months, 6 months, and 1 year. Discussion The goals of this exploratory clinical trial are to: develop a safe, feasible, and time-limited protocol effect of immediate (post-injury) treatment with fluoxetine for use by orthopedic providers and other non-mental health care providers treating victims of musculoskeletal trauma (Aim 1), and test the for preliminary effects of the protocol on development of PTSD symptomology and physical recovery in these patients (Aim 2). This study is novel in that it strives to prevent the development of symptomology from the time of injury and empowers surgeons to manage their patients in a more holistic manner. Trial registration ClinicalTrials.gov, NCT04850222. Registered on April 20, 2021.

Comparison of Validated Videofluoroscopic Outcomes of Pharyngeal Residue: Concordance Between a Perceptual, Ordinal, and Bolus-Based Rating Scale and a Normalized Pixel-Based Quantitative Outcome. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2022; 65:2510-2517. [PMID: 35749660 PMCID: PMC9584126 DOI: 10.1044/2022_jslhr-21-00659] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 03/09/2022] [Accepted: 04/11/2022] [Indexed: 06/15/2023]
Abstract
PURPOSE This study compared the concordance between two validated videofluoroscopic pharyngeal residue outcome scales used in clinical and research settings: the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) and the Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) percent residue metric. METHOD Two trained raters completed independent and blinded videofluoroscopic ratings of both DIGEST efficiency and ASPEKT percent pharyngeal residue outcomes for bolus trials of 5 cc Varibar thin liquid (n = 223), thin liquid comfortable cup sips (n = 223), and 5 cc Varibar thin honey (n = 223). Spearman's rho and Kruskal-Wallis analyses were performed for each bolus type. RESULTS Significant associations between DIGEST and ASPEKT pharyngeal residue outcomes were noted for 5 cc thin (r = .54, p < .001), cup sip thin (r = .41, p < .001), and 5 cc thin honey (r = .60, p < .001) bolus trials. ASPEKT percent residue increased across worsening DIGEST efficiency ordinal scale levels, with a main effect for each bolus type. Post hoc analysis revealed significant differences in the ASPEKT percent residue values between each DIGEST pairwise comparison for the thin cup sip bolus trial and for each pairwise comparison except between the moderate-to-severe (less than half vs. majority) ordinal levels for the 5 cc thin and 5 cc honey bolus trials, p < .05. CONCLUSIONS Perceptual, ordinal (DIGEST) and quantitative, pixel-based (ASPEKT) videofluoroscopic pharyngeal residue outcomes were associated in this data set of 669 bolus trials. Future research is warranted to confirm these results.

Abstract
BACKGROUND The use of metaphyseal cones and sleeves has improved the ability to manage tibial bone loss in revision total knee arthroplasty (TKA). The purpose of this study was to compare the outcomes of three systems used for tibial metaphyseal reconstruction in revision TKA. METHODS We performed a retrospective review of a consecutive series of 723 revision TKAs, including 145 (20%) knee revisions using tibial cones or sleeves. We compared porous tantalum (TM) cones, titanium (Ti) cones and titanium sleeves. The mean follow-up was 2.5 years. RESULTS The rate of revision for any reason was similar among all groups. Revision-free survival rates were similar among all systems studied at a mean follow-up of 2.5 years (TM cones 93%, Ti cones 94%, titanium sleeves 89%). Ti cones had a lower complication rate (6%) compared to TM cones (24%) and sleeves (29%). TM cones (15%) and titanium sleeves (13%) had higher reoperation rates (for any cause) than Ti cones (2%). Radiographic loosening was higher for sleeves (11%) than TM and Ti cones (2%). CONCLUSION Metaphyseal reconstruction for tibial bone loss in revision TKA using tantalum cones, titanium cones and titanium sleeves showed successful and comparable early clinical outcomes at a mean follow-up of 2.5 years with higher rates of radiographic loosening for titanium sleeves. Level of Evidence: III.

Abstract
BACKGROUND Studies have demonstrated an increased risk of musculoskeletal (MSK) injury after concussion in collegiate and professional athletes, but there has been relatively little study of this relationship in younger athletes. OBJECTIVE To determine the odds of experiencing a subsequent MSK injury after concussion in high school athletes. It was hypothesized that concussion would increase the risk of MSK injury within 365 days of the concussion event. DESIGN Retrospective observational study. SETTING Twelve high school sports programs. PARTICIPANTS Athletes (n = 14,461) from athletic training room records queried between 2010 and 2017. INDEPENDENT VARIABLES History of concussion and history of concussion and MSK injury in the year preceding MSK injury. MAIN OUTCOME MEASURES General estimating equation analyses were conducted to examine the odds of MSK injury related to (1) concussion within the preceding 365 days of injury; and (2) concussion and MSK injury within the preceding 365 days of concussion. RESULTS Respectively, 8% and 8.3% of athletes were identified with a concussion and MSK injury. After controlling for gender and sport, athletes with a concussion and prior MSK injury (odds ratio = 2.19, 95% confidence interval: 1.02-4.67) and athletes with a concussion alone (odds ratio = 1.67, 95% confidence interval: 1.15-2.44) both had higher odds of experiencing a subsequent MSK injury compared to athletes without prior concussion. CONCLUSIONS High school athletes who sustain a concussion have elevated odds of MSK injury at rates comparable to those for collegiate athletes. These findings support the use of neuromuscular-based rehabilitation and injury prevention protocols in the post-concussion period. These findings may also suggest exploring methods to modify concussion return-to-play criteria with the goal to reduce the risk of future MSK injury.

Abstract
Introduction Continuous electroencephalography (EEG) is an important monitoring modality in the intensive care unit and a key skill for critical care fellows (CCFs) to learn. Our objective was to evaluate with CCFs an EEG educational curriculum on a web-based simulator. Methods This prospective cohort study was conducted at a major academic medical center in Florida. After Institutional Review Board approval, 13 CCFs from anesthesiology, surgery, and pulmonary medicine consented to take an EEG curriculum. A 25-item EEG assessment was completed at baseline, after 10 EEG interpretations with a neurophysiologist, and after 10 clinically relevant EEG-based simulations providing clinical EEG interpretation hints. A 50-minute tutorial podcast was viewed after the baseline assessment. Main assessment outcomes included multiple outcomes related to web-based simulator performance: percent of hints used, percent of first words on EEG interpretation correct, and percent hint-based EEG interpretation score correct, with higher scores indicating more correct answers. Participants completed a 25-item EEG assessment before (baseline) and after the web-based simulator. Results All 13 CCFs completed the curriculum. Between scenarios, there were differences in percent of hints used (F9,108 = 11.7, p < 0.001), percent of first words correct (F9,108 = 13.6, p < 0.001), and overall percent hint-based score (F9,108 = 14.0, p < 0.001). Nonconvulsive status epilepticus had the lowest percent of hints used (15%) and the highest hint-based score (87%). Overall percent hint-based score (mean across all scenarios) was positively correlated with change in performance as the number of correct answers on the 25-item EEG assessment from before to after the web-based simulator activity (Spearman’s rho = 0.67, p = 0.023). Conclusions A self-paced EEG interpretation curriculum involving a flipped classroom and screen-based simulation each requiring less than an hour to complete significantly improved CCF scores on the EEG assessment compared to baseline.

Early reduction in postoperative pain is associated with improved long-term function after shoulder arthroplasty: a retrospective case series. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2022; 33:1023-1030. [PMID: 35286469 DOI: 10.1007/s00590-022-03242-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 02/28/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Mixed modalities are frequently utilized in total shoulder arthroplasty (TSA) to control pain, improve patient satisfaction, reduce narcotics use and facilitate earlier discharge. We investigate the relationship between early postoperative pain control and long-term functional outcomes after shoulder arthroplasty. METHODS A retrospective review identified 294 patients (314 shoulders) who underwent anatomic or reverse TSA and received a continuous cervical paravertebral nerve block perioperatively. Opioid and non-opioid analgesics were also available to the patients in an "as needed" capacity to augment perioperative pain control. In addition to demographic and surgical characteristics, the impact on functional outcomes of relative pain (i.e., a patient's subjective pain relative to the entire cohort), pain gradient (i.e., the slope of a patient's subjective pain), and opioid consumption during the first 24 h postoperatively were assessed. Shoulder function was assessed using validated outcome measures collected at 2 year follow-up. Outcomes were measured using American Shoulder and Elbow Surgeons questionnaire (ASES), Shoulder Pain and Disability Index (SPADI), SPADI-130, Raw and Normalized Constant Score, SST-12 and UCLA score. RESULTS Patients younger than 65, females, reverse TSA, revisions, and preoperative opioid users had worse functional outcomes. On univariate analysis, increased pain perioperatively (> 50% percentile relative pain) was associated with decreased function at 2 years when analyzed with all seven outcome scores (P < .001 for all), reaching minimal clinically important difference (MCID) using the Constant Score. On multivariate analysis, increased pain in the first 24 h postoperatively (assessed on a continuous scale) was independently associated with worse ASES, SPADI, and SPADI-130 scores. Intraoperative ketamine administration and opioid consumption in the 24 h postoperative period did not influence long-term shoulder function. CONCLUSION Patients reporting reduced pain after TSA demonstrated improved shoulder function with the Constant score at 2 years postoperatively in both univariate and multivariate analysis. Larger-scale investigation may be warranted to see if this is true for other functional outcome measures. LEVEL OF EVIDENCE III, treatment study.

“Linear Relationship Between Electromyography and Shear Wave Elastography Measurements Persists in Deep Muscles of the Upper Extremity”. J Electromyogr Kinesiol 2022; 63:102645. [PMID: 35189570 PMCID: PMC9115669 DOI: 10.1016/j.jelekin.2022.102645] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Revised: 01/31/2022] [Accepted: 02/06/2022] [Indexed: 11/26/2022] Open
Abstract
Recent works have demonstrated a linear relationship between muscle activation and shear modulus in various superficial muscles. As such, it may be possible to overcome limitations of traditional electromyography (EMG) methods by assessing activation using shear wave elastography. However, the relationship has not been wholly validated in deep muscles. This study measured the association between squared shear wave velocity, which is related to shear modulus, and activation within superficial and deep muscles. This relationship was also compared between surface and intramuscular EMG electrodes. We simultaneously recorded EMG and shear wave velocity in one deep (brachialis) and one superficial (brachioradialis) muscle in ten healthy individuals during isometric elbow flexion across a wide range of contraction intensities. Muscle activation and squared shear wave velocity demonstrated good reliability (ICC > 0.75) and showed a linear relationship (P < 0.05) for all muscle/EMG electrode type combinations (study conditions) after down-sampling. Study condition was not a significant within-subject factor to the slope or intercept of the relationship (P > 0.05). This work demonstrates that activation of both superficial and deep muscles can be assessed noninvasively using ultrasound shear wave elastography and is a critical step toward demonstrating elastography's utility as an alternative to EMG.

Abstract
BACKGROUND Information on the safety of placement, maintenance, and removal of peripheral nerve blocks in the presence of therapeutic or prophylactic antithrombotics is limited to case reports. METHODS In this retrospective, descriptive study, we examined the use of femoral and gluteal or subgluteal sciatic perineural catheters in 146 patients on antithrombotics who received lower limb amputation (LLA) above or below the knee at the University of Florida Health Shands Hospital between January 2015 and December 2019. We searched patient surgical records for complications such as bleeding, nerve damage, infection, and hematoma during placement, maintenance, and removal of the perineural catheters. RESULTS In this cohort of 146 patients on antithrombotics, there was 1 episode of hematoma with an estimated incidence of 1 of 146 (0.68%, 95% confidence interval [CI], 0.02-3.76). This patient developed a hematoma at the location of the femoral catheter and required a blood transfusion. This patient was on aspirin daily and subcutaneous heparin 3 times per day and had a normal coagulation profile during their hospital stay. CONCLUSIONS This report investigates bleeding complications of femoral and sciatic perineural catheters in patients undergoing LLA on antithrombotics. We found that, except for 1 patient, most patients on varying combinations of antithrombotics did not experience bleeding complications related to the femoral and sciatic perineural catheters.

Abstract
Introduction Cardiac output/pulmonary blood flow measurement is an important way to assess patients during the perioperative period, as well as patients who are critically ill. Current methods of assessing cardiac output have limitations. One indicator of cardiac output may be the expired carbon dioxide (CO2) partial pressure response to intravenous sodium bicarbonate (IVSB), which is rapidly converted to CO2. Methods We conducted an initial evaluation of the relationship between expired CO2 partial pressure and blood flow after a bolus of IVSB. To assess this relationship, we used a cardiopulmonary bypass circuit with predetermined blood flows in a laboratory trial and then assessed 18 patients undergoing surgery requiring cardiopulmonary bypass. Results For the laboratory portion of this pilot study, higher peak expired CO2, faster time to reach peak, higher area under the curve, and greater kurtosis of peak were observed at higher cardiac output flow rates, and higher mean expired CO2 was significantly associated with higher flow rates (p < 0.001). In the human study, higher mean (p = 0.023) and peak expired CO2 (p = 0.028) were both significantly associated with higher cardiac output flow rates. Conclusions This technique may be a way to intermittently assess cardiac output or improve accuracy when used in conjunction with other continuous output monitors.

Abstract
OBJECTIVES We describe observed improvements in nontechnical or "higher-order" deficiencies and cognitive performance skills in an anesthesia residency cohort for a 1-year time interval. Our main objectives were to evaluate higher-order, cognitive performance and to demonstrate that simulation can effectively serve as an assessment of cognitive skills and can help detect "higher-order" deficiencies, which are not as well identified through more traditional assessment tools. We hypothesized that simulation can identify longitudinal changes in cognitive skills and that cognitive performance deficiencies can then be remediated over time. METHODS We used 50 scenarios evaluating 35 residents during 2 subsequent years, and 18 of those 35 residents were evaluated in both years (post graduate years 3 then 4) in the same or similar scenarios. Individual basic knowledge and cognitive performance during simulation-based scenarios were assessed using a 20- to 27-item scenario-specific checklist. Items were labeled as basic knowledge/technical (lower-order cognition) or advanced cognitive/nontechnical (higher-order cognition). Identical or similar scenarios were repeated annually by a subset of 18 residents during 2 successive academic years. For every scenario and item, we calculated group error scenario rate (frequency) and individual (resident) item success. Grouped individuals' success rates are calculated as mean (SD), and item success grade and group error rates are calculated and presented as proportions. For all analyses, α level is 0.05. RESULTS Overall PGY4 residents' error rates were lower and success rates higher for the cognitive items compared with technical item performance in the operating room and resuscitation domains. In all 3 clinical domains, the cognitive error rate by PGY4 residents was fairly low (0.00-0.22) and the cognitive success rate by PGY4 residents was high (0.83-1.00) and significantly better compared with previous annual assessments (P < 0.05). Overall, there was an annual decrease in error rates for 2 years, primarily driven by decreases in cognitive errors. The most commonly observed cognitive error types remained anchoring, availability bias, premature closure, and confirmation bias. CONCLUSIONS Simulation-based assessments can highlight cognitive performance areas of relative strength, weakness, and progress in a resident or resident cohort. We believe that they can therefore be used to inform curriculum development including activities that require higher-level cognitive processing.

Blood flow restriction exercise to attenuate postoperative loss of function after total knee replacement: a randomized pilot study. Eur J Transl Myol 2021; 31. [PMID: 34459574 PMCID: PMC8495367 DOI: 10.4081/ejtm.2021.9932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 07/16/2021] [Indexed: 11/22/2022] Open
Abstract
Aging well is directly associated with a healthy lifestyle. The focus of this paper is to relate that attenuation of postoperative loss of muscle function after a total knee arthroplasty (TKA) is an important consideration. Because patients usually do not tolerate standard high-resistance exercise in the preoperative or postoperative period, they often experience a decline in strength and function. Therefore, we tested the feasibility and acceptability of an alternative low-resistance exercise protocol with blood flow restriction (BFR) using a tourniquet in the preoperative period for patients awaiting TKA. We recruited patients undergoing a TKA and randomized six to the BFR exercise for 4 weeks prior to surgery and four to standard of care (no exercise). We measured physical function using the Short Physical Performance Battery (SPPB), the 6-Minute Walk Test (6MWT), leg strength (peak torque), and pain (numerical pain score) 4 to 5 weeks preoperatively and 2 weeks postoperatively. The clinical management, e.g., anesthetic management, did not differ between groups. No complications were observed. Our findings demonstrate the feasibility and acceptability of the BFR intervention. Although preliminary and not powered for comparison, the BFR group demonstrated less decline in SPPB following surgery (−2.2, 95%CI:−4.4,0.1) compared to the no exercise group (−4.8, 95%CI:−7.8,−1.7). No differences were noted for the 6MWT, leg strength, and pain measurements. We conclude that preoperative low-resistance exercise using the BFR is feasible and acceptable, and this test warrants investigation as an intervention to potentially attenuate the postoperative loss of physical function after TKA.

Effects of a Single Rapid Infusion System on Platelet Function in Stored Whole Blood: An Ex Vivo Study. Cureus 2021; 13:e16518.

Abstract
Introduction Rapid infusion systems (RIS) are used to warm and rapidly infuse crystalloids and blood products. Current guidelines do not approve of platelet transfusion through a RIS, but data supporting these guidelines are scarce. Our hypothesis was that an infusion of whole blood through a RIS would degrade platelet quantity, impede viscoelastic clot strength, and inhibit platelet aggregation response to adenosine diphosphate pathway (ADP) activation. Methods Ten iterations of a simulated scenario of transfusing whole blood via a single brand and make of RIS (Belmont Fluid Management System 2000, Belmont Medical Technologies, Billerica, MA) were performed. Units of whole blood, which were two to nine days old, were leukoreduced prestorage. Blood was used to prime the RIS and then warmed and infused at 100 mL/min into a reservoir. Blood samples were collected before and immediately after infusion. Samples were tested for platelet count, size, and viscoelastic clot strength using thromboelastographic and aggregation assays. Results The study sample (n = 10) included platelets with an average age of 5.3 days. The infusion through the RIS had a detrimental effect on all the maximal amplitudes (MA) of viscoelastic testing: MA ADP (mean difference = −18.7 mm; 95% CI: −24.1 to −13.3, P = 0.004), MA rapid thromboelastography (MA rTEG) (mean difference = −6.0; 95% CI: −10.0 to −2.0, P = 0.008), MA TEG (mean difference = −7.1; 95% CI: −10.9 to −3.4, P = 0.004), mean platelet volume (MPV) (mean difference = −0.3; 95% CI: −0.6 to −0.1, P = 0.02), and platelet count (mean difference = −68.3 × 103/µL; 95% CI: −86.9 to −49.7, P = 0.004). Conclusions Platelet quantity, viscoelastic clot strength, and platelet aggregation response to ADP each decline after infusion through a RIS. Further studies regarding microaggregates and platelet activation are required.

Abstract
BACKGROUND The obturator nerve runs along the posterolateral walls of the bladder and electrosurgical stimulation in this region can result in adductor spasm which can occur suddenly and unexpectedly with potentially catastrophic results. METHODS Sixty patients were prospectively randomized to receive either a single-injection ultrasound-guided obturator nerve block (ONB) or intravenous rocuronium after induction of general anesthesia (i.e., neuromuscular block [NMB]). The primary objective was to compare the incidence of adductor spasm during posterolateral bladder tumor resection when ONB or NMB was used. Secondary objectives included assessment of fall risk and incidence of adverse events. RESULTS Five patients in the ONB group and six in the NMB group had nonlateral wall lesions. One patient in the ONB group suffered a cardiac arrest after induction of general anesthesia. Of the remaining 48 patients, six (10.2%) experienced adductor spasm. Most of these patients were in the NMB group (5/24, 20.8%), with only one patient (1/24, 4.2%) experiencing obturator reflex in the ONB group; this difference was not statistically significant (P=0.19). Patients in the ONB group had a greater decrease in mean hip adductor strength. Our study population was found to be at high risk of falls before surgery. There were no statistically significant group differences in the Timed Up and Go test, with time to perform the test increasing in both groups. CONCLUSIONS Both techniques are safe and efficacious for preventing adductor spasm. Our data and experience suggest that the ONB is relatively easy to perform and should be considered in patients with posterolateral bladder tumors.

Knee pain trajectories over 18 months in non-Hispanic Black and non-Hispanic White adults with or at risk for knee osteoarthritis. BMC Musculoskelet Disord 2021; 22:415. [PMID: 33952243 PMCID: PMC8101224 DOI: 10.1186/s12891-021-04284-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Accepted: 04/14/2021] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Pain is the hallmark symptom of knee osteoarthritis (OA), and varies widely across individuals. Previous research has demonstrated both fluctuating and stable pain trajectories in knee OA using various time periods. Changes in pain assessed quarterly (i.e. 3-month intervals) in knee OA are relatively unknown. The current study aimed to investigate temporal variations in pain over a one and a half year period (18 months) based on quarterly characteristic pain assessments, and to examine differences in pain patterns by sociodemographic and baseline pain characteristics. METHODS The sample included a prospective cohort of 188 participants (mean age 58 years; 63% female; 52% non-Hispanic Black) with or at risk for knee OA from an ongoing multisite investigation of ethnic/race group differences. Knee pain intensity was self-reported at baseline and quarterly over an18-month period. Baseline pain assessment also included frequency, duration, and total number of pain sites. Group-based trajectory modeling was used to identify distinct pain trajectories. Multinomial logistic regression was used to examine associations between sociodemographic characteristics, risk factors, and pain trajectory groups. RESULTS Pain trajectories were relatively stable among a sample of adults with knee pain. Four distinct pain trajectories emerged in the overall sample, with the largest proportion of participants (35.1%) classified in the moderate-high pain group. There were significant relationships between age, education, income, ethnicity/race and trajectory group; with younger, less educated, lower income, and non-Hispanic Black participants had a greater representation in the highest pain trajectory group. CONCLUSIONS Pain remained stable across a one and a half-year period in adults with or at risk for knee osteoarthritis, based on quarterly assessments. Certain sociodemographic variables (e.g. ethnicity/race, education, income, age) may contribute to an increased risk of experiencing greater pain.

Abstract
Measurements of physical function after total knee arthroplasty (TKA) are uncertain and require investments for special equipment, space, and staff. Therefore, we evaluated the Short Physical Performance Battery (SPPB) 4 to 6 weeks preoperatively and 2 weeks following TKA as this test battery addresses lower extremity strength, coordination, and balance, without additional special investments. For context, we also employed the Six-Minute Walk test (6MWT) and peak torque knee extension. Our analysis consisted of three women and one man, with average ages of 68.3±3.9 years. Patients showed a decrease in all functional measurements: SPPB (mean change: -4.8±1.9, 44% decrease), 6MWT (-0.37±.21 m/s, 34% decrease), and peak torque (-11.8±8.8°/s, 68% decrease). Our findings suggest the SPPB is feasible and can be integrated easily in daily clinical practice.

Abstract
Introduction The objective of the pilot study was to determine the association between learning preferences and improvement in the American Academy of Neurology Residency In-Service Training Examination (RITE) scores from postgraduate year 2 (PGY-2) to postgraduate year 3 (PGY-3) in neurology residents. Methods Neurology residents at the University of Florida were approached to participate, and their consent was obtained. VARK inventory, representing four modalities (visual, aural, read/write, kinesthetic) of learning preferences, was completed by participants. Participants could pick more than one modality. The number of responses in each sensory domain was recorded, with higher numbers indicating stronger preference. Residents’ performance on the RITE was recorded for PGY-2 and PGY-3. Results Seventeen residents completed the VARK inventory and 16 had data for RITE. Residents demonstrated overall positive change in RITE from PGY-2 to PGY-3 (mean change = 6%; 95%CI: 4%, 9%). The median number of responses was highest for the kinesthetic domain (median = 7, range = 1-12), followed by visual (median = 6, range = 2-12), aural (median = 4, range = 1-10), and read/write (median = 4, range = 1-10). Among VARK domains, the number of responses in read/write had the strongest correlation with mean change in RITE performance from PGY-2 to PGY-3 (r = 0.45; 95%CI: -0.08, 0.78); residents in the high read/write group (number of response above median) had greater mean change in RITE performance (9%; 95%CI: 6%, 12%) while those in the low read/write group showed little to no increase in RITE from PGY-2 to PGY-3 (2%; 95%CI: -1%, 6%). Conclusions Higher VARK survey responses in the read/write domain were related to greater change in RITE scores from PGY-2 to PGY-3. These findings seem intuitively obvious considering the format of the RITE. These pilot data permit further investigation of individual resident learning preference and how it relates to test performance. By understanding a resident’s learning style, both educators and the resident will have an awareness of areas that need to be improved to be successful, which may be via remedial curricula and self-study activities.
