Bodily-tactile early intervention: a pilot study of the role of maternal touch and emotional availability in interactions between three children with visual impairment and additional disabilities and their mothers.

Background: Children with visual impairment and additional disabilities (VIAD) have difficulty accessing the visual information related to their parents' facial expressions and gestures. Similarly, it may be hard for parents to detect their children's subtle expressions. These challenges in accessibility may compromise emotional availability (EA) in parent-child interactions. The systematic use of the bodily-tactile modality for expressive and receptive communicative functions may function as a strategy to compensate for a child's lack of vision. This multiple-case study explored the effects of a bodily-tactile early intervention for three mothers and their one-year-old children with VIAD. Methods: Video data from baseline, intervention, and follow-up sessions were analyzed using a bodily-tactile coding procedure and EA Scales. Results: During the intervention, all mothers began to use a more bodily-tactile modality in early play routines and in different communicative functions. They increased their use of anticipatory cues, noticing responses, and tactile signs. Moreover, the children were more emotionally available to their mothers during the intervention and follow-up compared to the baseline. Conclusion: The results indicated that, during a short intervention, mothers could adopt a systematic use of the bodily-tactile modality in interactions with their children with VIAD. The results also suggest that, when mothers increased flexibility in communication channels, it was positively linked to their children's EA.

Presacral malakoplakia presenting as foot drop: a case report.

BACKGROUND: Malakoplakia is a rare condition characterized by inflammatory masses with specific histological characteristics. These soft tissue masses can mimic tumors and tend to develop in association with chronic or recurrent infections, typically of the urinary tract. A specific defect in innate immunity has been described. In the absence of randomized controlled trials, management is based on an understanding of the biology and on case reports. CASE PRESENTATION: Here we describe a case of presacral malakoplakia in a British Indian woman in her late 30s, presenting with complex unilateral foot drop. Four years earlier, she had suffered a protracted episode of intrapelvic sepsis following a caesarean delivery. Resection of her presacral soft tissue mass was not possible. She received empiric antibiotics, a cholinergic agonist, and ascorbic acid. She responded well to medical management both when first treated and following a recurrence of symptoms after completing an initial 8 months of therapy. Whole exome sequencing of the patient and her parents was undertaken but no clear causal variant was identified. CONCLUSIONS: Malakoplakia is uncommon but the diagnosis should be considered where soft tissue masses develop at the site of chronic or recurrent infections. Obtaining tissue for histological examination is key to making the diagnosis. This case suggests that surgical resection is not always needed to achieve a good clinical and radiological outcome.

Anatomic and reverse shoulder arthroplasty for management of type B2 and B3 glenoids: a matched-cohort analysis.

BACKGROUND: Severe glenohumeral osteoarthritis (GHOA) with posterior glenoid erosion remains challenging to address for shoulder surgeons. Whereas anatomic total shoulder arthroplasty (TSA) has historically been the treatment of choice, reverse shoulder arthroplasty (RSA) offers an alternative option. Limited evidence exists directly comparing these 2 treatments in a similar patient population. The purpose of this study was to compare the clinical outcomes of patients with GHOA and Walch type B2 and B3 glenoid morphologies treated with TSA vs. RSA. METHODS: We performed a multicenter retrospective cohort study of patients with GHOA who were treated with primary shoulder arthroplasty and had a minimum follow-up period of 2 years. Preoperative computed tomography was used to determine type B2 and B3 glenoid morphology as described by the modified Walch classification. Three-dimensional perioperative planning software was used to characterize glenoid retroversion and humeral subluxation. Patients were categorized based on type of arthroplasty (TSA or RSA) and were matched 1:1 by sex, Walch classification, and age. Patient-reported outcome measures, active range of motion, presence and severity of glenoid loosening, and complications were compared. The percentage of patients who reached previously established clinically significant thresholds of the minimal clinically important difference and substantial clinical benefit for the American Shoulder and Elbow Surgeons score was also comparatively assessed. RESULTS: In total, 202 patients (101 per group) with GHOA and type B2 or B3 glenoids were included in the 1:1 matched analysis. The mean length of follow-up (± standard deviation) was 39 ± 18.7 months. The cohorts were well matched, with no differences in sex, age, American Society of Anesthesiologists score, body mass index, preoperative glenoid morphology (Walch classification), glenoid retroversion, or posterior subluxation (P > .05). RSA was associated with a lower postoperative visual analog scale pain score (0.5 in RSA group vs. 1.2 in TSA group, P = .036); however, no other no other significant differences in patient-reported significant differences in patient-reported outcome measures were found. Most patients in both groups (95.0% in TSA group vs. 98.0% in RSA group, P = .436) reached the minimal clinically important difference, and 82% of TSA patients and 90% of RSA patients reached the substantial clinical benefit value (P = .292). No significant differences in the overall complication rate (P = .781) and active range of motion were found, with the exception of internal rotation (scored on a numeric scale) being worse in the RSA group (2.7 preoperatively and 5.2 postoperatively in RSA group vs. 3.9 and 6.5, respectively, in TSA group; P < .001). Baseplate loosening occurred in 2 RSA cases, and 29 TSA cases had glenoid radiolucencies (P < .001), with 3 grossly loose glenoid components. CONCLUSION: Primary RSA results in short-term outcomes largely comparable to those of TSA in patients with Walch type B2 or B3 glenoid morphology. Both TSA and RSA provide substantial clinical benefit to patients with significant posterior glenoid wear.

Psychotherapy Treatment of Generalized Anxiety Disorder Improves When Conducted Under Narrow Band Green Light.

Background and Goals: Psychotherapy is one of the most highly recommended and practiced approaches for the treatment of Generalized anxiety disorder (GAD). Commonly defined as excessive worry that is uncontrollable, GAD is one of the most prevalent psychiatric disorders. Anxiety is also one of the most common associated symptoms of migraine. Exposing migraineurs to narrow band green light (nbGL) reduces their anxiety and anxiety-like physiological symptoms such as throat tightness, shortness of breath, and palpitations. Here, we sought to determine whether the reduced anxiety described by our patients was secondary to the reduced headache or independent of it. The goal of the current study was therefore to determine whether exposure to nbGL can reduce anxiety in GAD patients who are not migraineurs. Patients and Methods: Included in this open-label, proof-of-concept, prospective study were 13 patients diagnosed with moderate-to-severe GAD. We used the State-Trait Anxiety Inventory Questionnaire (Y-1) to compare anxiety level before and after each 45-minutes psychotherapy session conducted in white light (WL) (intensity = 100±5 candela/m2) vs nbGL (wavelength = 520±10nm (peak ± range), intensity = 10±5 candela/m2). Results: Here, we show that psychotherapy sessions conducted under nbGL increase positive and decrease negative feelings significantly more than psychotherapy sessions conducted under regular room light (χ2 = 0.0001). Conclusion: The findings provide initial evidence for the potential benefit of conducting psychotherapy sessions for patients suffering GAD under nbGL conditions. Given the absence of side effects or risks, we suggest that illuminating rooms used in psychotherapy with nbGL be considered an add-on to the treatment of GAD.

Lessons to learn from the analysis of routine health data from Moria Refugee Camp on Lesvos, Greece.

BACKGROUND: Refugees in humanitarian settings commonly experience many health needs and barriers to access healthcare; health data from these settings are infrequently reported, preventing effective healthcare provision. This report describes health needs of refugees in Moria Camp on Lesvos, Greece-Europe's largest refugee camp. METHODS: A set of routinely collected service data of 18 131 consultations of 11 938 patients, attending a primary care clinic in the camp over 6 months in 2019-20, was analysed retrospectively, focusing on chronic health conditions. RESULTS: The most frequent chronic conditions were musculoskeletal pain (25.1%), mental health (15.9%), cardiac (12.7%) and endocrine conditions (8.9%). In all, 70.4% of consultations were for acute health problems, with high rates of injuries and wounds (20.8%), respiratory infections (12.5%), gastroenteritis (10.7%) and skin problems (9.7%), particularly scabies. CONCLUSIONS: The prevalence of acute and chronic health problems is high in this setting, with some likely attributable to the deplorable living conditions in the camp. Despite its magnitude, the interpretability of routine health data is limited. A research agenda is identified, and a framework for chronic disease management in refugee camps is proposed.

Bodily-tactile early intervention for a mother and her child with visual impairment and additional disabilities: a case study.

PURPOSE: Congenital visual impairment and additional disabilities (VIAD) may hamper the development of a child's communication skills and the quality of overall emotional availability between a child and his/her parents. This study investigated the effects of bodily-tactile intervention on a Finnish 26-year-old mother's use of the bodily-tactile modality, the gestural and vocal expressions of her one-year-old child with VIAD, and emotional availability between the dyad. MATERIALS AND METHODS: Mixed methods were used in the video analysis. The child's and his mother's bodily-tactile and gestural expressions were analyzed using a coding procedure. Applied conversation analysis was used to further analyse the child's emerging gestural expressions in their sequential interactive context. Emotional availability scales were used to analyze the emotional quality of the interaction. RESULTS: The results showed that the mother increased her use of the bodily-tactile modality during the intervention, especially in play and tactile signing. The child imitated new signs and developed new gestural expressions based on his bodily-tactile experiences during the intervention sessions. His vocalizations did not change. Emotional availability remained stable. CONCLUSIONS: The case study approach allowed the in-depth investigation of the components contributing to the emergence of gestural expressions in children with VIAD.Implications for rehabilitationBodily-tactile modality may compensate for the absence of a child's vision in child-parent interactions.Bodily-tactile early intervention may be effective in guiding caregivers to use bodily-tactile modality in interacting with their child with VIAD.Caregivers' use of bodily-tactile modality in interactions may contribute to the development of gestural expressions in a child with VIAD.The use of bodily-tactile modality in interactions may improve the emotional connection between children with VIAD and their caregivers.

Outcomes After Anatomic and Reverse Shoulder Arthroplasty for the Treatment of Glenohumeral Osteoarthritis: A Propensity Score-Matched Analysis.

BACKGROUND: Reverse shoulder arthroplasty (RSA) is increasingly being utilized for the treatment of primary osteoarthritis. However, limited data are available regarding the outcomes of RSA as compared with anatomic total shoulder arthroplasty (TSA) in the setting of osteoarthritis. METHODS: We performed a retrospective matched-cohort study of patients who had undergone TSA and RSA for the treatment of primary osteoarthritis and who had a minimum of 2 years of follow-up. Patients were propensity score-matched by age, sex, body mass index (BMI), preoperative American Shoulder and Elbow Surgeons (ASES) score, preoperative active forward elevation, and Walch glenoid morphology. Baseline patient demographics and clinical outcomes, including active range of motion, ASES score, Single Assessment Numerical Evaluation (SANE), and visual analog scale (VAS) for pain, were collected. Clinical and radiographic complications were evaluated. RESULTS: One hundred and thirty-four patients (67 patients per group) were included; the mean duration of follow-up (and standard deviation) was 30 ± 10.7 months. No significant differences were found between the TSA and RSA groups in terms of the baseline or final VAS pain score (p = 0.99 and p = 0.99, respectively), ASES scores (p = 0.99 and p = 0.49, respectively), or SANE scores (p = 0.22 and p = 0.73, respectively). TSA was associated with significantly better postoperative active forward elevation (149° ± 13° versus 142° ± 15°; p = 0.003), external rotation (63° ± 14° versus 57° ± 18°; p = 0.02), and internal rotation (≥L3) (68.7% versus 37.3%; p < 0.001); however, there were only significant baseline-to-postoperative improvements in internal rotation (gain of ≥4 levels in 53.7% versus 31.3%; p = 0.009). The overall complication rate was 4.5% (6 of 134), with no significant difference between TSA and RSA (p = 0.99). Radiolucent lines were observed in association with 14.9% of TSAs, with no gross glenoid loosening. One TSA (1.5%) was revised to RSA for the treatment of a rotator cuff tear. No loosening or revision was encountered in the RSA group. CONCLUSIONS: When performed for the treatment of osteoarthritis, TSA and RSA resulted in similar short-term patient-reported outcomes, with better postoperative range of motion after TSA. Longer follow-up is needed to determine the ultimate value of RSA in the setting of osteoarthritis. LEVEL OF EVIDENCE: Therapeutic Level III .

Neighborhood socioeconomic disadvantage does not predict outcomes or cost after elective shoulder arthroplasty.

BACKGROUND: There is growing evidence that the variation in value of shoulder arthroplasty may be mediated by factors external to surgery. We sought to determine if neighborhood-level socioeconomic deprivation is associated with postoperative outcomes and cost among patients undergoing elective shoulder arthroplasty. METHODS: We identified 380 patients undergoing elective total shoulder arthroplasty (anatomic or reverse) between 2015 and 2018 in our institutional registry with minimum 2-year follow-up. Each patient's home address was mapped to the area deprivation index in order to determine the level of socioeconomic disadvantage. The area deprivation index is a validated composite measure of 17 census variables encompassing income, education, employment, and housing conditions. Patients were categorized into 3 groups based on socioeconomic disadvantage (least disadvantaged [deciles 1-3], middle group [4-6], and most disadvantaged [7-10]). Bivariate analysis was performed to determine associations between the level of socioeconomic deprivation with hospitalization time-driven activity-based costs and 2-year postoperative American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), and pain intensity scores. RESULTS: Overall 19% of patients were categorized as most disadvantaged. These patients were found to have equivalent preoperative pain intensity (P = .51), SANE (P = .50), and ASES (P = .72) scores compared to the middle and least disadvantaged groups, as well as similar outcome improvement at 2 years postoperatively (ASES): least disadvantaged group [35.7-84.3], middle group [35.1-82.4], and most disadvantaged group [37.1-84.0] [P = .56]; SANE: least disadvantaged group [31.8-87.1], middle group [30.8-84.8], and most disadvantaged group [34.2-85.1] [P = .42]; and pain: least disadvantaged group [6.0-0.97], middle group [6-0.97], and most disadvantaged group [5.6-0.80] [P = .88]. No differences in hospitalization costs were noted between groups (P = .77). CONCLUSIONS: Patients undergoing elective shoulder arthroplasty residing in the most disadvantaged neighborhoods demonstrate equivalent preoperative and postoperative outcomes as others, without incurring higher costs. These findings support continued efforts to provide equitable access to orthopedic care across the socioeconomic spectrum.

Patients with limited health literacy have worse preoperative function and pain control and experience prolonged hospitalizations following shoulder arthroplasty.

BACKGROUND: Patients with limited health literacy (LHL) may have difficulty understanding and acting on medical information, placing them at risk for potential misuse of health services and adverse outcomes. The purposes of our study were to determine (1) the prevalence of LHL in patients undergoing inpatient shoulder arthroplasty, (2) the association of LHL with the degree of preoperative symptom intensity and magnitude of limitations, (3) and the effects of LHL on perioperative outcomes including postoperative length of stay (LOS), total inpatient costs, and inpatient opioid consumption. METHODS: We retrospectively identified 230 patients who underwent elective inpatient reverse or anatomic shoulder arthroplasty between January 2018 and May 2021 from a prospectively maintained single-surgeon registry. The health literacy of each patient was assessed preoperatively using the validated 4-item Brief Health Literacy Screening Tool. Patients with a Brief Health Literacy Screening Tool score ≤ 17 were categorized as having LHL. The outcomes of interest were preoperative patient-reported outcome scores and range of motion, LOS, total postoperative inpatient opioid consumption, and total inpatient costs as calculated using time-driven activity-based costing methodology. Univariate analysis was performed to determine associations between LHL and patient characteristics, as well as the outcomes of interest. Multivariable linear regression modeling was used to determine the association between LHL and LOS while controlling for potentially confounding variables. RESULTS: Overall, 58 patients (25.2%) were classified as having LHL. Prior to surgery, these patients had significantly higher rates of opioid use (P = .002), more self-reported allergies (P = .007), and worse American Shoulder and Elbow Surgeons scores (P = .001), visual analog scale pain scores (P = .020), forward elevation (P < .001), and external rotation (P = .022) but did not significantly differ in terms of any additional demographic or clinical characteristics (P > .05). Patients with LHL had a significantly longer LOS (1.84 ± 0.92 days vs. 1.57 ± 0.58 days, P = .012) but did not differ in terms of total hospitalization costs (P = .65) or total inpatient opioid consumption (P = .721). On multivariable analysis, LHL was independently predictive of a significantly longer LOS (ß, 0.14; 95% confidence interval, 0.02-0.42; P = .035). CONCLUSION: LHL is commonplace among patients undergoing elective shoulder arthroplasty and is associated with greater preoperative symptom severity and activity intolerance. Its association with longer hospitalizations suggests that health literacy is an important factor to consider for postoperative disposition planning.

Posterior reversible encephalopathy syndrome associated with use of Atezolizumab for the treatment of relapsed triple negative breast cancer.

Posterior reversible encephalopathy syndrome (PRES) is a complex neurological disorder with multiple clinical manifestations including headaches, seizures, and altered mental status. It is associated with many conditions including malignancy and medications including chemotherapy and immunotherapy. We report the case of a 56-year old female with a history of advanced triple negative breast cancer treated with atezolizumab (a PD-L1 inhibitor), paclitaxel and ipatasertib (investigational AKT inhibitor), who developed hypertension, confusion, and imaging findings consistent with PRES.

Clinical Outcomes After Reverse Total Shoulder Arthroplasty in Patients With Primary Glenohumeral Osteoarthritis Compared With Rotator Cuff Tear Arthropathy: Does Preoperative Diagnosis Make a Difference?

INTRODUCTION: The primary purpose of this study was to evaluate the clinical outcomes of patients who underwent reverse total shoulder arthroplasty performed for primary glenohumeral osteoarthritis (GHOA) with an intact rotator cuff compared with rotator cuff tear arthropathy (CTA). METHODS: This was a retrospective review of prospectively collected data including consecutive patients who underwent primary reverse total shoulder arthroplasty for GHOA or CTA with a minimum of 2-year follow-up. Baseline patient demographics and clinical outcomes including active range of motion, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numerical Evaluation, and visual analog scale for pain were collected. Univariate and multivariate regression analyses were performed to evaluate the effect of preoperative diagnosis on clinical outcomes. RESULTS: Patients with a preoperative diagnosis of GHOA demonstrated significantly better postoperative active forward elevation (138.6° versus 127.3°; P < 0.01), external rotation (54.2° versus 43.8°; P < 0.01), and change in internal rotation (Δ 2.1 points versus Δ 1.2 points; P < 0.01). Patients with GHOA demonstrated significantly better postoperative ASES (86.8 versus 76.6; P < 0.01), Single Assessment Numerical Evaluation (89.7 versus 78.5; P < 0.01), and visual analog scale scores (0.63 versus 1.2; P < 0.01). Minimal clinically important difference for ASES score was achieved by 97.5% of patients with GHOA compared with 86.7% of patients with CTA (P < 0.01), whereas substantial clinical benefit was achieved by 90.4% of patients with GHOA and 71.7% of patients with CTA (P < 0.01). After a multivariate linear regression analysis, postoperative ASES scores were independently associated with previous ipsilateral shoulder surgery (P = 0.042), preoperative ASES score (P = 0.01), and primary diagnosis of GHOA (P < 0.01). CONCLUSION: RTSA performed in patients with GHOA and an intact rotator cuff is associated with improved functional and clinical outcomes compared with those patients treated for CTA. LEVEL OF EVIDENCE: Level III Therapeutic Study.

Primary reverse total shoulder arthroplasty performed for glenohumeral arthritis: does glenoid morphology matter?

BACKGROUND: Indications for reverse total shoulder arthroplasty (RTSA) have expanded to include primary glenohumeral osteoarthritis (GHOA) with an intact rotator cuff. Limited evidence exists on RTSA in patients with primary GHOA and no posterior glenoid wear (Walch A1, A2, and B1 morphologies). The purpose of this retrospective cohort study was to determine if glenoid morphology is associated with clinical outcomes in patients undergoing RTSA for primary GHOA. METHODS: A retrospective review of prospectively collected data was performed in patients undergoing primary RTSA for GHOA with a minimum of 2-year clinical follow-up. Preoperative computed tomography and magnetic resonance imaging were used to categorize glenoid morphology as described by the modified Walch classification. Pre- and postoperative American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Single Assessment Numeric Evaluation (SANE), visual analog scale (VAS) pain scores, and range of motion (ROM) measurements were compared across Walch glenoid subtypes. The percentage of patients that reached previously established clinically significant thresholds for minimal clinically important difference (MCID) and substantial clinical benefit (SCB) was also comparatively assessed. Multivariable analysis was used to evaluate the association between glenoid morphology and postoperative ASES score while controlling for potentially confounding variables. RESULTS: Of the 247 consecutive patients, 197 were available at a minimum 2-year follow-up (80%). Significant improvements were seen in ASES, VAS pain, SANE, and ROM from baseline to final postoperative follow-up in the combined patient cohort (all P < .001). Most (98.0%) patients reached MCID, and 90.9% of patients reached SCB for ASES threshold. No significant differences were found among Walch subtypes in terms of preoperative to postoperative improvement in ASES (P = .39), SANE (P = .4), VAS pain (P = .49), forward elevation (P = .77), external rotation (P = .45), or internal rotation (P= 0.1). The only significant difference in postoperative outcomes between Walch glenoid subtypes was higher postoperative ASES scores among type B3 glenoids compared with type A1 glenoids (P = .03) on univariate analysis. However, no individual Walch glenoid subtype was associated with lower postoperative ASES scores on multivariable analysis (P > .05). CONCLUSION: Primary RTSA provides excellent short-term outcomes in patients with glenohumeral arthritis with intact rotator cuff, regardless of the degree of preoperative glenoid deformity. Surgeons can use these data to support the use of RTSA for glenohumeral arthritis in a more standardized way.

Variation in the Profit Margin for Different Types of Total Joint Arthroplasty.

BACKGROUND: As health care shifts to a value-based model with bundled-payment methods, it is important to understand the costs and reimbursements of arthroplasty procedures that represent the largest expenditure of Medicare. The aim of the present study was to characterize the variation in (1) total hospital costs, (2) reimbursement, and (3) profit margin for different arthroplasty procedures. METHODS: The total hospital costs of total knee arthroplasty (TKA), total hip arthroplasty (THA), anatomic total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), and total ankle arthroplasty (TAA) were calculated with use of time-driven activity-based costing at an orthopaedic institution from 2018 to 2020. The average reimbursement for each type of procedure was determined. Profit margin, defined as the reimbursement profit after direct costs, was calculated by deducting the average time-drive activity-based total hospital costs from the reimbursement value. Multivariate analyses were performed to evaluate the associations between costs, reimbursement, and profit margins. RESULTS: There were 13,545 arthroplasty procedures analyzed for this study, including 6,636 TKAs, 5,902 THAs, 346 TSAs, 577 RSAs, and 84 TAAs. Costs and reimbursement were highest for TAA. THA and TKA resulted in the highest profit margins, whereas RSA resulted in the lowest. The strongest associations with profit margin were private insurance (0.46547), age (-0.22732), and implant cost (-0.19240). CONCLUSIONS: THA and TKA had greater profit margins overall than TAA and upper-extremity arthroplasty in general. Profit margins for RSA, TSA, and TAA were all at least 28% lower than those for TKA or THA. Lower-volume arthroplasty procedures were associated with decreased profit margins. Study findings suggest that optimizing implant costs and length of stay are important for sustaining institutional fiscal health when performing shoulder and ankle arthroplasty surgery.

Predictors of poor and excellent outcomes after reverse total shoulder arthroplasty.

BACKGROUND: Favorable clinical and functional outcomes can be achieved with reverse total shoulder arthroplasty (RSA). Given the expanding utilization of RSA in the United States, understanding the factors that influence both excellent and poor outcomes is increasingly important. METHODS: A single-surgeon prospective registry was used to identify patients who underwent RSA from 2015 to 2018 with a minimum of 2 years' follow-up. An excellent postoperative clinical outcome was defined as a final American Shoulder and Elbow Surgeons (ASES) score in the top quartile of ASES scores. A poor outcome was defined as an ASES score in the bottom quartile. Logistic regression was used to determine preoperative characteristics associated with both excellent and poor outcomes. RESULTS: A total of 338 patients with a mean age of 71.5 years (standard deviation [SD], 6.4 years) met the inclusion and exclusion criteria. The average preoperative ASES score for the entire cohort was 35.3 (SD, 16.4), which improved to 82.4 (SD, 16.1) postoperatively (P < .001). Univariate analysis demonstrated that a diagnosis of primary osteoarthritis (OA), private insurance, and higher preoperative ASES scores were significantly associated with achieving excellent outcomes (P < .01 for all). Variables predictive of poor outcomes were workers' compensation status (P = .03), depression (P = .02), a preoperative diagnosis of rotator cuff tear arthropathy (P < .01), preoperative opioid use (P < .01), a higher number of allergies (P < .01), and prior ipsilateral shoulder surgery (P < .01). Multivariate regression analysis demonstrated that OA (odds ratio [OR], 5.6; 95% confidence interval [CI], 1.2-26.5; P = .03) and private insurance (OR, 2.7; 95% CI, 1.12-6.5; P = .02) correlated with excellent outcomes whereas a higher number of reported allergies (OR, 0.83; 95% CI, 0.71-0.97; P = .02), self-reported depression (OR, 0.39; 95% CI, 0.16-0.99; P =.04), a history of ipsilateral shoulder surgery (OR, 0.36; 95% CI, 0.15-0.87; P =.02), and preoperative opioid use (OR, 0.26; 95% CI, 0.09-0.76; P = .01) were predictive of poor outcomes. CONCLUSIONS: A preoperative diagnosis of primary OA is the strongest predictor of excellent clinical outcomes following RSA. Patients with an increasing number of reported allergies, self-reported depression, a history of ipsilateral shoulder surgery, and preoperative opioid use are significantly more likely to achieve poor outcomes after RSA. Given the increasing utilization of RSA, this information is important to appropriately counsel patients regarding postoperative expectations.

Rotator cuff fatty infiltration and muscle atrophy: relation to glenoid deformity in primary glenohumeral osteoarthritis.

BACKGROUND: Muscle atrophy (MA) and fatty infiltration (FI) are degenerative processes of the rotator cuff musculature that have incompletely understood relationships with the development of eccentric glenoid wear in the setting of primary glenohumeral osteoarthritis (GHOA). METHODS: All patients with GHOA and an intact rotator cuff who underwent both magnetic resonance imaging and computed tomography scans of the affected shoulder prior to total shoulder arthroplasty between 2015 and 2020 were identified from a prospectively maintained registry. Rotator cuff MA was measured quantitatively on sequential sagittal magnetic resonance images, whereas FI was assessed on sagittal magnetic resonance imaging slices using the Goutallier classification. Preoperative computed tomography scans were reconstructed using automated 3-dimensional software to determine glenoid retroversion, glenoid inclination, and humeral head subluxation. Glenoid deformity was classified according to the Walch classification. Univariate and multivariable regression analyses were performed to characterize associations between age, sex, muscle area, FI, and glenoid morphology. RESULTS: Among the 127 included patients, significant associations were found between male sex and larger overall rotator cuff musculature (P < .01), increased ratio of the posterior rotator cuff (PRC) to the subscapularis area (P = .01), and glenoid retroversion (19° vs. 14°, P < .01). Larger supraspinatus and PRC muscle size was correlated with increased retroversion (r = 0.23 [P = .006] for supraspinatus and r = 0.25 [P = .004] for PRC) and humeral head subluxation (r = 0.25 [P = .004] for supraspinatus and r = 0.28 [P = .001] for PRC). The ratio of PRC muscle size to anterior rotator cuff muscle size was not associated with evidence of eccentric glenoid wear (P > .05). After we controlled for confounding factors, increasing glenoid retroversion was associated with high-grade infraspinatus FI (ß, 6.8; 95% confidence interval, 2.9-10.7; P < .01) whereas larger PRC musculature was predictive of a Walch type B (vs. type A) glenoid (odds ratio, 1.3; 95% confidence interval, 1.0-1.5; P = .04). CONCLUSION: Patients with eccentric glenoid wear in the setting of primary GHOA and an intact rotator cuff appear to have both larger PRC musculature and higher rates of infraspinatus FI. Although the temporal and causal relationships of these associations remain ambiguous, MA and FI should be considered 2 discrete processes in the natural history of GHOA.

Functional somatic syndromes are associated with suboptimal outcomes and high cost after shoulder arthroplasty.

BACKGROUND: The presence of functional somatic syndromes (chronic physical symptoms with no identifiable organic cause) in patients undergoing elective joint arthroplasty may affect the recovery experience. We explored the prevalence of functional somatic syndromes among shoulder arthroplasty patients, as well as their association with postoperative outcomes and costs. METHODS: We identified 480 patients undergoing elective total shoulder arthroplasty (anatomic or reverse) between 2015 and 2018 in our institutional registry with minimum 2-year follow-up. Medical records were queried for the presence of 4 well-recognized functional somatic syndromes: fibromyalgia, irritable bowel syndrome, chronic headaches, and chronic low-back pain. Multivariable linear regression modeling was used to determine the independent association of these diagnoses with hospitalization time-driven activity-based costs and 2-year postoperative American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and pain scores. RESULTS: Nearly 1 in 5 patients (17%) reported at least 1 functional somatic syndrome. These patients were more likely to be women, to be chronic opioid users, to report more allergies, to have a diagnosis of anxiety, and to have shoulder pathology other than degenerative joint disease (all P ≤ .001). After multivariable adjustment, the presence of at least 1 functional somatic syndrome was independently predictive of lower 2-year ASES (-9.75 points) and SANE (-7.63 points) scores and greater residual pain (+1.13 points) (all P ≤ .001). When considered cumulatively, each additional functional disorder was linked to a stepwise decrease in ASES and SANE scores and an increase in residual pain (P < .001). These patients also incurred higher hospitalization costs, with a stepwise rise in costs with an increasing number of disorders (P < .001). CONCLUSIONS: Functional somatic syndromes are common in patients undergoing shoulder arthroplasty and correlate with suboptimal outcomes and greater resource utilization. Efforts to address the biopsychosocial determinants of health that affect the value proposition of shoulder arthroplasty should be prioritized in the redesign of care pathways and bundling initiatives.

Protocol for a multicenter, randomised controlled trial of surgeon-directed home therapy vs. outpatient rehabilitation by physical therapists for reverse total shoulder arthroplasty: the SHORT trial.

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) has emerged as a successful surgery with expanding indications. Outcomes may be influenced by post-operative rehabilitation; however, there is a dearth of research regarding optimal rehabilitation strategy following RTSA. The primary purpose of this study is to compare patient reported and clinical outcomes after RTSA in two groups: in one group rehabilitation is directed by formal, outpatient clinic-based physical therapists (PT group) as compared to a home therapy group, in which patients are instructed in their rehabilitative exercises by surgeons at post-operative appointments (HT group). Secondary aims include comparisons of complications, cost of care and quality of life between the two groups. METHODS: This randomised controlled trial has commenced at seven sites across the United States. Data is being collected on 200 subjects by clinical research assistants pre-operatively and post-operatively at 2, 6, and 12 weeks, 6 months, 1 and 2 year visits. The following variables are being assessed: American Shoulder and Elbow Surgeons (ASES), pain level using the numeric pain scale, the Single Assessment Numeric Evaluation (SANE) score, and shoulder active and passive range of motion for analysis of the primary aim. Chi square and t-tests will be used to measure differences in baseline characteristics of both groups. Repeated measures linear mixed effects modeling for measurement of differences will be used for outcomes associated with ASES and SANE and scores, and range of motion measures. Secondary aims will be analyzed for comparison of complications, cost, and quality of life assessment scores using data obtained from the PROMIS 29 v. 2, questionnaires administered at standard of care post-operative visits, and the electronic health record. Subjects will be allowed to crossover between the PT and HT groups, and analysis will include both intention-to-treat including patients who crossed over, and a second with cross-over patients removed, truncated to the time they crossed over. DISCUSSION: RTSA is being performed with increasing frequency, and the optimal rehabilitation strategy is unclear. This study will help clarify the role of formal physical therapy with particular consideration to outcomes, cost, and complications. In addition, this study will evaluate a proposed rehabilitation strategy. TRIAL REGISTRATION: This study is registered as NCT03719859 at ClincialTrials.gov .

Rising to Ostrom's challenge: an invitation to walk on the bright side of public governance and public service.

In this programmatic essay, we argue that public governance scholarship would benefit from developing a self-conscious and cohesive strand of "positive" scholarship, akin to social science subfields like positive psychology, positive organizational studies, and positive evaluation. We call for a program of research devoted to uncovering the factors and mechanisms that enable high performing public policies and public service delivery mechanisms; procedurally and distributively fair processes of tackling societal conflicts; and robust and resilient ways of coping with threats and risks. The core question driving positive public administration scholarship should be: Why is it that particular public policies, programs, organizations, networks, or partnerships manage do much better than others to produce widely valued societal outcomes, and how might knowledge of this be used to advance institutional learning from positives?

Rotator cuff fatty infiltration and muscle atrophy do not impact clinical outcomes after reverse total shoulder arthroplasty for glenohumeral osteoarthritis with intact rotator cuff.

BACKGROUND: The clinical significance of rotator cuff muscle quality following reverse total shoulder arthroplasty (RTSA) remains uncertain. The purpose of this study was to evaluate the influence of rotator cuff fatty infiltration (FI) and muscle atrophy (MA) on clinical outcomes following RTSA for glenohumeral osteoarthritis (GHOA). METHODS: One hundred eight shoulders with primary GHOA that underwent RTSA with a lateralized glenosphere for GHOA with a minimum of 2-year follow-up were identified from a prospectively maintained registry. Each rotator cuff muscle was assessed on preoperative magnetic resonance imaging for FI and quantitative amount of MA. Pre- and postoperative outcomes included American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score, Single Assessment Numerical Evaluation (SANE) score, visual analog scale pain score, and range of motion (ROM) measurements. RESULTS: Eighty-one patients with a mean age of 70.7 ± 5.4 years (range: 57-85) were included who underwent RTSA with a mean follow-up of 2.1 years (range: 2-3.9 years). There was a significant improvement in all outcome measures postoperatively (P < .01). Twenty-two patients (27.1%) had moderate to severe combined infraspinatus and teres minor FI. There was no significant difference in the postoperative external rotation or clinical outcomes compared with those patients with only mild FI (P > .05). Forty-three patients (53.1%) had moderate to severe global rotator cuff FI. There was no significant difference in postoperative outcomes compared with those patients with only mild FI (P < .01). Univariate analysis did not reveal any significant association between the degree of FI or MA of any individual rotator cuff muscle and postoperative clinical outcomes or ROM. The size ratio of the posterior rotator cuff to the subscapularis muscle was positively correlated with preoperative SANE scores but negatively correlated with absolute postoperative and change in preoperative to postoperative SANE scores. However, there were no significant correlations between this size ratio and the other outcome measures. CONCLUSION: Rotator cuff muscle quality as assessed by MA and FI does not impact clinical outcomes following RTSA with a lateralized glenosphere in patients with GHOA and an intact rotator cuff.
