Abstract
BACKGROUND Cuff tear arthropathy (CTA) can be successfully treated with various types of shoulder arthroplasty. While reverse total shoulder arthroplasty (RSA) is commonly used to treat CTA, CTA hemiarthroplasty (CTA-H, hemiarthroplasty with an extended humeral articular surface) can also be effective in patients with preserved glenohumeral elevation and an intact coracoacromial (CA) arch. As the value of arthroplasty is being increasingly scrutinized, cost containment has become a priority. The objective of this study was to assess hospitalization costs and improvements in joint-specific measures and health-related quality of life for these two types of shoulder arthroplasty in the management of CTA. METHODS Seventy-two patients (39 CTA-H and 33 RSA) were treated during the study time period using different selection criteria for each of the two procedures: CTA-H was selected in patients with retained active elevation, an intact CA arch, and an intact subscapularis, while RSA was selected in patients with pseudoparalysis or glenohumeral instability. The Simple Shoulder Test (SST) was used as a joint-specific patient-reported outcome measure. Improvement in quality-adjusted life years was measured using the Short Form 36. Costs associated with inpatient care were collected from hospital financial records. Univariate and multivariate analyses focused on determining predictors of hospitalization costs and improvements in patient-reported outcomes. RESULTS Significant improvements in SST and Short Form 36 physical component scores were seen in both groups. Inpatient hospitalization costs were significantly higher in the RSA group than that in the CTA-H group ($15,074 ± $1614 vs. $10,389 ± $1948, P < .001), driven primarily by supplies including the cost of the prosthesis ($9005 ± $2521 vs. $4715 ± $2091, P < .001). The diagnosis of diabetes was an independent predictor of higher inpatient hospitalization costs for both groups. There were no independent predictors for quality-adjusted life year improvements. SST improvement in the CTA-H group was significantly higher in patients with lower preoperative SST scores. CONCLUSION Using a standard algorithm of CTA-H for shoulders with retained active elevation and an intact CA arch and RSA for poor active elevation or glenohumeral instability, both procedures led to significant improvements in health-related quality of life and joint-specific measures. Costs were significantly lower for patients meeting the selection criteria for CTA-H. Further value analytics are needed to compare the relative cost effectiveness of RSA and CTA-H for patients with CTA having retained active elevation, intact CA arch, and intact subscapularis.

Abstract
BACKGROUND With increasing emphasis on value-based care and the heavy demands on the US health care budget, surgeons must be cognizant of factors that drive cost and quality of patient care. Our objective was to determine patient-level drivers of lower costs and improved health-related quality of life (HRQoL) in 2 anatomic shoulder arthroplasty procedures: total shoulder arthroplasty (TSA) and ream-and-run arthroplasty. METHODS This study included 222 TSAs and 211 ream-and-run arthroplasties. Simple Shoulder Test, Single Assessment Numeric Evaluation, and Short Form 36 scores were collected preoperatively and 2 years postoperatively. Quality-adjusted life-years (QALYs) were calculated as a measure of HRQoL. Univariate and multivariate analyses determined factors significantly associated with decreased hospitalization costs and improved HRQoL. RESULTS In the TSA group, female sex, lower American Society of Anesthesiologists class, diagnosis other than capsulorrhaphy arthropathy, lower pain score, and higher Single Assessment Numeric Evaluation score were associated with decreased total hospitalization costs; in addition, female sex was an independent predictor of lower total costs. Insurance other than workers' compensation, a diagnosis of chondrolysis, and higher optimism led to greater QALY gains, but a diagnosis of capsulorrhaphy arthropathy was the only independent predictor of greater QALY gains. In the ream-and-run arthroplasty group, older age, lower body mass index (BMI), lower American Society of Anesthesiologists class, insurance other than Medicaid, diagnosis other than capsulorrhaphy arthropathy, no history of surgery, higher preoperative Simple Shoulder Test score, and higher preoperative Short Form 36 Physical Component Summary score were associated with lower total costs; moreover, lower BMI was an independent predictor of lower costs. Higher preoperative optimism was an independent predictor of greater QALY gains. CONCLUSIONS Identifying factors associated with decreased costs and increased quality is becoming increasingly important in value-based care. This study identified fixed (sex and diagnosis) and modifiable (BMI) factors that drive decreased hospitalization costs and increased HRQoL improvements in shoulder arthroplasty patients. Higher preoperative patient optimism is a consistent predictor of improved HRQoL for both TSA patients and ream-and-run arthroplasty patients, and further study on optimizing the influence of patient expectations and optimism may be warranted.

Abstract
Importance Despite advances in cancer treatment and cancer-related outcomes, disparities in cancer mortality remain. Lower rates of cancer prevention screening and consequent delays in diagnosis may exacerbate these disparities. Better understanding of the association between area-level social determinants of health and cancer screening may be helpful to increase screening rates. Objective To examine the association between area deprivation, rurality, and screening for breast, cervical, and colorectal cancer in patients from an integrated health care delivery system in 3 US Midwest states (Minnesota, Iowa, and Wisconsin). Design, Setting, and Participants In this cross-sectional study of adults receiving primary care at 75 primary care practices in Minnesota, Iowa, and Wisconsin, rates of recommended breast, cervical, and colorectal cancer screening completion were ascertained using electronic health records between July 1, 2016, and June 30, 2017. The area deprivation index (ADI) is a composite measure of social determinants of health composed of 17 US Census indicators and was calculated for all census block groups in Minnesota, Iowa, and Wisconsin (11 230 census block groups). Rurality was defined at the zip code level. Using multivariable logistic regression, this study examined the association between the ADI, rurality, and completion of cancer screening after adjusting for age, Charlson Comorbidity Index, race, and sex (for colorectal cancer only). Main Outcomes and Measures Completion of recommended breast, cervical, and colorectal cancer screening. Results The study cohorts were composed of 78 302 patients eligible for breast cancer screening (mean [SD] age, 61.8 [7.1] years), 126 731 patients eligible for cervical cancer screening (mean [SD] age, 42.6 [13.2] years), and 145 550 patients eligible for colorectal cancer screening (mean [SD] age, 62.4 [7.0] years; 52.9% [77 048 of 145 550] female). The odds of completing recommended screening were decreased for individuals living in the most deprived (highest ADI) census block group quintile compared with the least deprived (lowest ADI) quintile: the odds ratios were 0.51 (95% CI, 0.46-0.57) for breast cancer, 0.58 (95% CI, 0.54-0.62) for cervical cancer, and 0.57 (95% CI, 0.53-0.61) for colorectal cancer. Individuals living in rural areas compared with urban areas also had lower rates of cancer screening: the odds ratios were 0.76 (95% CI, 0.72-0.79) for breast cancer, 0.81 (95% CI, 0.79-0.83) for cervical cancer, and 0.93 (95% CI, 0.91-0.96) for colorectal cancer. Conclusions and Relevance Individuals living in areas of greater deprivation and rurality had lower rates of recommended cancer screening, signaling the need for effective intervention strategies that may include improved community partnerships and patient engagement to enhance access to screening in highest-risk populations.

Abstract
BACKGROUND We sought to compare the functional outcomes, radiographic outcomes, and complications of trapeziectomy and flexor carpi radialis (FCR) to abductor pollicis longus (APL) side-to-side tendon transfer with or without suture-button suspensionplasty for thumb basilar joint arthritis. METHODS Patients treated with and without suture-button suspensionplasty were compared over a 6-year period. Data were reviewed for complications and functional outcomes, including grip and pinch strength, range of motion, and visual analog scale (VAS) pain scores. Plain radiographs were independently reviewed at initial presentation and at final follow-up, including proximal phalanx length, trapezial space height, and trapezial height ratio. RESULTS Seventy thumb arthroplasties were performed in 70 patients. Trapeziectomy with FCR-APL side-to-side tendon transfer was performed in 39 patients, and trapeziectomy with FCR-APL side-to-side tendon transfer with suture-button suspensionplasty was performed in 31 patients. Mean length of follow-up was 28.4 ± 3.9 and 23.8 ± 2.6 months, respectively. Postoperative grip, oppositional and appositional pinch strength, and VAS pain scores improved compared with preoperative values, but were not significantly different based on suture-button suspensionplasty. Percentage decline in trapezial space ratio was significantly different between groups at 36.7% and 20.4% for procedures with and without suture-button suspensionplasty, respectively indicating that the trapezial space was better maintained within the suture suspension cohort. The incidence of postoperative complications, including surgical site infection, paresthesias, reoperation, complex regional pain syndrome, and symptomatic subsidence, was not significantly different between groups. CONCLUSIONS Trapeziectomy with FCR to APL side-to-side tendon transfer with and without suture-button suspensionplasty results in comparable improvement in pain, grip strength, and functional parameters. Suture-button suspensionplasty results in significantly greater preservation of trapezial space.

Abstract
Ongoing payment reform in dialysis necessitates better patient outcomes and lower costs. Suggested improvements to processes of care for maintenance dialysis patients are abundant; however, their impact on patient-important outcomes is unclear. This systematic review included comparative randomized controlled trials or observational studies with no restriction on language, published from 2000 to 2014, involving at least 5 adult dialysis patients who received a minimum of 6 months of follow-up. The effect size was pooled and stratified by intervention strategy (multidisciplinary care [MDC], home dialysis, alternate dialysis settings, and electronic health record implementation). Heterogeneity (I2) was used to assess the variability in study effects related to study differences rather than chance. Of the 1988 articles screened, 25 international studies with 74,833 maintenance dialysis patients were included. Interventions with MDC or home dialysis were associated with a lower mortality (hazard ratio [HR] = 0.72, 95% confidence interval [CI] 0.61, 0.84, I2 = 41.6%; HR = 0.57, 95% CI 0.41, 0.81, I2 = 89.0%; respectively) and hospitalizations (incidence rate ratio [IRR] = 0.68, 95% CI 0.51, 0.91, I2 = NA; IRR = 0.88, 95% CI 0.64, 1.20, I2 = 79.6%; respectively). Alternate dialysis settings also were associated with a reduction in hospitalizations (IRR = 0.41, 95% CI 0.25, 0.69, I2 = 0.0%). This systematic review underscores the importance of multidisciplinary care, and also the value of telemedicine as a means to increase access to providers and enhance outcomes for those dialyzing at home or in alternate settings, including those with limited access to nephrology expertise because of travel distance.

Abstract
INTRODUCTION Musculoskeletal disease (MSD) is a major cause of disability in the global burden of disease, yet data regarding the magnitude of this burden in low and middle-income countries (LMICs) are lacking. The Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey was designed to measure incidence and prevalence of surgically treatable conditions, including MSD, in patients in LMICs. METHODS A countrywide survey was done in Nepal using SOSAS in May-June 2014. Clusters were chosen based on population weighted random sampling. Chi squared tests and multivariate logistic regression assessed associations between demographic variables and MSD. RESULTS Self-reported MSDs were seen in 14.8% of survey respondents with an unmet need of 60%. The majority of MSDs (73.9%) occurred between 1 and 12 months prior to the survey. Female sex (OR = 0.6; p < 0.000), access to motorized transport (for secondary facility, OR = 0.714; p < 0.012), and access to a tertiary health facility (OR = 0.512; p < 0.008) were associated with lower odds of MSD. DISCUSSION Based on this study, there are approximately 2.35 million people living with MSDs in Nepal. As the study identified non-availability, lack of money, and fear and/or lack of trust as the major barriers to orthopedic care in Nepal, future work should consider interventions to address these barriers. CONCLUSION There is a need to increase surgical capacity in LMICs; in particular, there is a need to bolster trauma and orthopedic care. Previous studies have suggested ways to allocate resources to build capacity. We recommend targeting the alleviation of these identified barriers in parallel with capacity building.

Abstract
OBJECTIVE To determine the prognosis of patients with non-secretory myeloma. Methods: We studied 124 patients diagnosed with multiple myeloma who had no monoclonal protein detected on serum and urine immunofixation at diagnosis and on all subsequent follow up testing (non-secretory myeloma). The overall survival (OS) of patients with non-secretory myeloma was compared with 7075 patients with typical myeloma seen during the same time period in whom a monoclonal protein was detected at the time of diagnosis. RESULTS One hundred and twenty four patients met criteria for non-secretory multiple myeloma. The median follow-up was 102 months (range, 1-204 months). The median progression free survival with initial therapy was 28.6 months, and the median OS was 49.3 months. There was a significant improvement in OS since 2001; median survival 99.2 versus 43.8 months (prior to 2001) versus 99.2 months (2001-2012), P<0.001. OS was superior in patients with a normal baseline FLC ratio (n=10) compared to patients with an abnormal ratio (n=19), medians not reached in both groups. Prior to 2001, OS was similar in non-secretory myeloma (n=86) and secretory myeloma (n=4011), median 3.6 versus 3.5 years, respectively, P=0.63. However, among patients diagnosed between 2001-2012, OS was superior in non-secretory myeloma (n=36) compared to secretory myeloma (n=2942), median 8.3 versus 5.4 years, respectively, P=0.03. CONCLUSIONS Non-secretory myeloma is an uncommon subtype of multiple myeloma. In the last decade, there has been an improvement in the survival of non-secretory myeloma, and appears superior to secretory myeloma. This article is protected by copyright. All rights reserved.

Abstract
The list of asthma masqueraders grows, emphasizing the need for a careful analysis of the patient suffering from cough, wheezing and/or dyspnea. The present case report describes a 23-year-old patient with spastic vocal cord adduction, initially treated as bronchial asthma. Severe disruption in her arterial blood gases was present. The vocal cord adduction persisted in spite of valium anesthesia. The patient's symptoms and signs were relieved with a tracheostomy. However, the vocal cord spasm persisted.
