Matthew Sniegowski, Michael Erlanger, Raul Velez-Montoya, Jeffrey L Olson Ophthalmology Department, University of Colorado School of Medicine, Rocky Mountain Lions Eye Institute, Aurora, CO, USA Purpose: To assess the change in ocular surface temperature between healthy phakic and pseudophakic patients.Methods: We included patients with no history of ocular disease other than cataract. Patients were divided into three groups: clear lens, cataract, and pseudophakic. All patients had two ocular surface digital thermal scans. An average of five surface points was used as the mean ocular surface temperature. Results were analyzed with a one-way analysis of variance and a Tukey’s least significance difference test. The patients were further divided into phakic and pseudophakic groups. Correlation coefficients between several variables were done in order to assess dependencies.Results: Fifty-six eyes (28 cataracts, 12 clear lenses, 16 pseudophakic) were enrolled. The mean ocular surface temperature in the cataract group was 34.14°C±1.51°C; clear lens: 34.43°C±2.27°C; and pseudophakic: 34.97°C±1.57°C. There were no statistical differences among the study groups (P=0.3). There was a nonsignificant negative correlation trend between age and surface temperature in the phakic group. The trend inverted in the pseudophakic group but without statistical significance.Conclusion: Although cataract extraction and intraocular lens implantation seem to induce a mild increase in ocular surface temperature, the effect is not clear and not significant. Keywords: digital thermal scans, intraocular lens implantation, cataract extraction

Kesenia Stafeeva, Michael Erlanger, Raul Velez-Montoya, Jeffrey L OlsonDepartment of Ophthalmology, University of Colorado School of Medicine, Rocky Mountain Lions Eye Institute, Colorado, CO, USAAbstract: This case report describes the clinical, autofluorescence, and optical coherent tomography findings in a patient with panocular argyrosis secondary to chronic intake of diluted silver nitrate salts in his water supply. An 86-year-old Caucasian male with a distinctive gray-bluish hue of the skin presented to our clinic, having developed a slow decrease in visual acuity in both eyes and nyctalopia for the past 2 years. Based on the patient's history of chronic intake of silver nitrate salts and a positive skin biopsy (performed by the dermatology department, data not shown), a diagnosis of panocular argyrosis was made. Fluorescein angiography showed choroidal blockage with a completely dark choroid. Fundus autofluorescence was within normal limits. Optical coherent tomography showed multiple excrescences of retinal pigment epithelium in both eyes. Although the drusen-like changes on fundus examination and retinal pigment epithelium changes may account for the diminished vision, the presence of concomitant nyctalopia suggests underlying damage of the photoreceptors.Keywords: silver nitrate, argyria, ocular argyrosis, fundus autofluorescence, optical coherent tomography

Delayed graft function (DGF) is a frequent complication of renal transplantation, particularly in the setting of transplantation of kidneys derived from deceased donors and expanded-criteria donors. DGF results from tubular epithelial cell injury and has i

Introduction: Digital health tools can be beneficial in the care of patients with chronic conditions and have the potential for widespread impact as readily scalable and cost-effective health interventions. However, benefits are often contingent on users sustaining their engagement with these tools over time. Sustained engagement with digital health tools can be challenging, and high rates of attrition from digital interventions are common. Inflammatory Bowel Disease (IBD) and irritable bowel syndrome (IBS) are prominent gastrointestinal conditions resulting in significant burdens for individuals and society. Emerging evidence suggests digital health tools can be beneficial for IBD and IBS management; however, it is not clear what barriers and enablers are experienced by people living with these conditions to sustaining their engagement with these tools, when necessary. Such knowledge could inform the tailoring of new and existing digital health tools to the needs of people living with IBD and/or IBS. This study will seek to identify the barriers and enablers of sustained engagement with digital health tools among adults living with IBD and/or IBS., Methods and Analysis: We will conduct semistructured interviews with a purposive sample of approximately 30 adults (>18 years) who (a) reside in Canada, (b) self-report that they have been diagnosed with IBD and/or IBS, (c) have ever used a digital health tool (ie, any application/platform) to manage their condition and (d) are capable of providing informed consent. Interviews will be audio and video recorded and transcribed verbatim. Data will be coded deductively and barriers and enablers to sustained engagement will be categorised in accordance with the Theoretical Domains Framework. Data analysis will be verified by a patient research partner., Ethics and Dissemination: The study has been approved by the Ottawa Health Science Network Research Ethics Board. The findings will inform the codevelopment of strategies to overcome modifiable barriers and leverage identified enablers of sustained engagement with digital health tools for IBD and IBS care. These strategies can inform the design of new, or modifications to existing, digital health tools for IBD and IBS care where sustained engagement is desirable. Strategies will be compiled into a guidebook and disseminated via the Inflammation, Microbiome and Alimentation: Gastro-Intestinal and Neuropsychiatric Effects (IMAGINE) Strategy for Patient Oriented Research chronic disease network in Canada., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objective: Physical activity is important for health, yet most young adults are insufficiently active. Physical activity is regulated in part, by habit, typically operationalised as automaticity. Little is known about the characteristics of automaticity, or whether broad bandwidth unidimensional measures of automaticity for physical activity are superior to narrower bandwidth multi- dimensional measures. Design: This secondary analysis ( N  = 238) investigated the nature of automaticity, and relations between the dimensions of automaticity, global automaticity, and physical activity. Main Outcome Measures: The structure of the Generic Multifaceted Automaticity Scale (GMAS) was examined by confirmatory factor analyses. Structural equation models were estimated to evaluate relations between automaticity (measured on the GMAS and the Self- Report Behavioral Automaticity Index, SRBAI) and device- measured activity. Results: The hypothesised 3- factor structure of the GMAS was rejected, in favour of a 2- factor solution. Lack of intention/control and efficiency were associated with global automaticity, but not physical activity. Global automaticity was associated with moderate to vigorous physical activity and daily steps, but not light physical activity. Conclusion: Multi- dimensional measures of automaticity may not provide a more nuanced understanding of automaticity when predicting overall physical activity.

Introduction: Despite the importance of timing of nerve surgery after peripheral nerve injury, optimal timing of intervention has not been clearly delineated. The goal of this study is to explore factors that may have a significant impact on clinical outcomes of severe peripheral nerve injury that requires reconstruction with nerve transfer or graft., Materials and Methods: Adult patients who underwent peripheral nerve transfer or grafting in Alberta were reviewed. Clustered multivariable logistic regression analysis was used to examine the association of time to surgery, type of nerve repair, and patient characteristics on strength outcomes. Cox proportional hazard regression analysis model was used to examine factors correlated with increased time to surgery., Results: Of the 163 patients identified, the median time to surgery was 212 days. For every week of delay, the adjusted odds of achieving Medical Research Council strength grade ≥ 3 decreases by 3%. An increase in preinjury comorbidities was associated with longer overall time to surgery (aHR 0.84, 95% CI 0.74-0.95). Referrals made by surgeons were associated with a shorter time to surgery compared to general practitioners (aHR 1.87, 95% CI 1.14-3.06). In patients treated with nerve transfer, the adjusted odds of achieving antigravity strength was 388% compared to nerve grafting; while the adjusted odds decreased by 65% if the injury sustained had a pre-ganglionic injury component., Conclusion: Mitigating delays in surgical intervention is crucial to optimizing outcomes. The nature of initial nerve injury and surgical reconstructive techniques are additional important factors that impact postoperative outcomes.

Background: Process evaluations conducted alongside clinical trials can improve understanding of treatment fidelity and provide contextual knowledge to aide interpretations of trial outcomes. We adopted a multiple-goals perspective to investigate treatment fidelity in two related pilot clinical trials of an adjuvant treatment for pediatric-onset Inflammatory Bowel Disease. This included a focus on barriers and enablers of performing trial-specific activities and of integrating those activities into daily life., Methods: We conducted one-time semi-structured interviews with a sub-sample of participants of the Resistant Starch in Pediatric Inflammatory Bowel Disease (NCT04522271) and Optimized Resistant Starch in Inflammatory Bowel Disease pilot trials (NCT04520594) and their caregivers (N = 42). The trials examined the effects of personalized food-derived resistant starches as an adjuvant therapy on intestinal microbiome functioning. Interviews were conducted within 3-months of participants completing or withdrawing from the trials. Interview guides with age-appropriate language were developed and pilot tested. Codes were identified inductively though conventional content analysis and then mapped to personal projects analysis, to explore how participants navigated between activities., Results: Three themes were identified. The first described the potential impact of living with inflammatory bowel disease and taking prescribed medications. The second described characteristics of trial-specific activities that might impact on their enactment, including perceived difficulty, and challenges following procedures or using trial materials. The third described the integration of trial-specific activities with school, work, household demands, and social, and extracurricular activities., Conclusions: Adjusting to living with inflammatory bowel disease and managing its treatment can impact trial participation. Integrating trial-related activities into daily life can be challenging, which could heighten perceptions of goal conflict. Findings can inform interpretations of trial outcomes and development of strategies for trial optimization and implementation of the adjuvant therapy into clinical practice., Competing Interests: AS and DM are co-founders of MedBiome, a clinical microbiomics company.

Introduction: Traumatic spinal cord injuries (tSCI) are common, often leaving patients irreparably debilitated. Therefore, novel strategies such as nerve transfers (NT) are needed for mitigating secondary SCI damage and improving function. Although different tSCI NT options exist, little is known about the epidemiological and injury-related aspects of this patient population. Here, we report such characteristics to better identify and understand the number and types of tSCI individuals who may benefit from NTs., Materials and Methods: Two peripheral nerve experts independently evaluated all adult tSCI individuals < 80 years old admitted with cervical tSCI (C1-T1) between 2005 and 2019 with documented tSCI severity using the ASIA Impairment Scale for suitability for NT (nerve donor with MRC strength ≥ 4/5 and recipient ≤ 2/5). Demographic, traumatic injury, and neurological injury variables were collected and analyzed., Results: A total of 709 tSCI individuals were identified with 224 (32%) who met the selection criteria for participation based on their tSCI level (C1-T1). Of these, 108 (15% of all tSCIs and 48% of all cervical tSCIs) were deemed to be appropriate NT candidates. Due to recovery, 6 NT candidates initially deem appropriate no longer qualified by their last follow-up. Conversely, 19 individuals not initially considered appropriate then become eligible by their last follow-up., Conclusion: We found that a large proportion of individuals with cervical tSCI could potentially benefit from NTs. To our knowledge, this is the first study to detail the number of tSCI individuals that may qualify for NT from a large prospective database.

Healthy lifestyle behaviors can improve health-related quality of life (HRQOL) in cancer survivors; but the combination of behaviors most important for HRQOL is not known. This study investigated the patterns of lifestyle behaviors among cancer survivors and differences in HRQOL between behavioral classes. Cancer survivors ( n = 2,463) were invited to participate in a cross-sectional survey. Participants ( N = 591) were predominately female (63%) and non-Hispanic White (90%). Survey items included self-reported physical activity, diet, smoking, sleep, HRQOL, and demographics. Behavioral classes were estimated by latent class analysis. Differences between classes were assessed by latent class regression. Compared with the "healthy lifestyles" class (higher probabilities of meeting aerobic/strength-based activity guidelines, high fruit/vegetable intake, and no sleep problems; 11% of sample), the "sleep and diet problems with inconsistent physical activity" class (higher probabilities of not meeting strength-based guidelines, low fruit/vegetable intake, some sleep problems; marginally higher probability of meeting aerobic guidelines; 41%) had poorer general and physical HRQOL. The "poor physical activity and diet" class (higher probabilities of not meeting aerobic/strength-based guidelines, low fruit/vegetable intake, and some sleep problems; 48%) had poorer general, physical, and mental HRQOL. Few participants exhibited healthy lifestyle patterns associated with HRQOL. The findings provide opportunities to develop differentiated multiple behavior-change interventions, targeted to two common patterns of behavior. A large subgroup of cancer survivors was susceptible to suboptimal physical activity and diet, warranting interventions exclusively targeting these behaviors. Another subgroup was susceptible to suboptimal physical activity, diet, and sleep, indicating interventions for this group should include strategies targeting these three behaviors., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Wearable devices are increasingly being integrated to improve prevention, chronic disease management and rehabilitation. Inferences about individual differences in device-measured physical activity depends on devices being worn long enough to obtain representative samples of behavior. Little is known about how psychological factors are associated with device wear time adherence. This study evaluated associations between identity, behavioral regulations, and device wear adherence during an ambulatory monitoring period. Young adults who reported insufficient physical activity (N = 271) were recruited for two studies before and after the SARS-COVID-19 pandemic declaration. Participants completed a baseline assessment and wore an Actigraph GT3X + accelerometer on their waist for seven consecutive days. Multiple linear regression indicated that wear time was positively associated with age, negatively associated with integrated regulation for physical activity, and greater after (versus before) the pandemic declaration. Overall, the model accounted for limited variance in device wear time. Exercise identity and exercise motivation were not associated with young adults' adherence to wearing the physical activity monitors. Researchers and clinicians can use wearable devices with young adults with minimal concern about systematic motivational biases impacting adherence to device wear., (© 2023.

Objective: To investigate preclinical data regarding the efficacy and biocompatibility of a bispecific protein, RO-101, with effects on VEGF-A and angiopoietin-2 (Ang-2) for use in retinal diseases., Design: Experimental study., Subjects: Brown Norway rats and New Zealand White Cross rabbits., Methods: Preclinical study data of RO-101 in terms of target-specific enzyme-linked immunosorbent assay binding affinity to VEGF-A and Ang-2, vitreous half-life, inhibition of target-receptor interaction, laser choroidal neovascular membrane animal model, human umbilical vein endothelial cell migration, and biocompatibility was obtained. Where applicable, study data were compared with other anti-VEGF agents., Main Outcome Measures: Binding affinity, half-life, biocompatibility, and efficacy of RO-101. Neovascularization prevention by RO-101., Results: RO-101 demonstrated a strong binding affinity for VEGF-A and Ang-2 and in vitro was able to inhibit binding to the receptor with higher affinity than faricimab. The half-life of RO-101 is comparable to or longer than current VEGF inhibitors used in retinal disease. RO-101 was found to be biocompatible with retinal tissue in Brown Norway rats. RO-101 was as effective or more effective than current anti-VEGF therapeutics in causing regression of neovascular growth in vivo., Conclusions: RO-101 is a promising candidate for use in retinal diseases. In preclinical models, RO-101 demonstrated similar or higher regression of neovascular growth to current anti-VEGF therapeutics with comparable or longer half-life. It also demonstrates a strong binding affinity for VEGF-A and Ang-2. It also was shown to be biocompatible with retinal tissue in animal studies, indicating potential compatibility for use in humans., Financial Disclosures: Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (© 2024 by the American Academy of Ophthalmology.)

Background: Care transitions are a challenging and crucial point for many high-risk patients; errors in medication use can result in preventable hospital readmissions, which worsen patient outcomes and result in decreased reimbursement and increased expenses for health systems. Transitions of care (TOC) is an opportunity where pharmacists in the outpatient setting can prevent medication errors and decrease hospital readmissions., Objective: The primary objective of this study was to evaluate the impact of pharmacist-conducted comprehensive medication reviews (CMRs) on 30-day hospital readmission rates. Secondary objectives included medication therapy problems (MTPs) identified, recommendations or interventions made, and impact on cost savings., Methods: Patients discharged from an Intermountain Health hospital with a high readmission risk score, value-based insurance plan, and primary care provider (PCP) at one of 21 primary care clinics were identified using an internal report. Patients were contacted by a pharmacist after discharge for a CMR; pharmacists then relayed any MTPs and therapeutic recommendations to the PCP before the patient's follow-up appointment. Data were retrospectively collected and analyzed., Results: A total of 2717 discharges occurred throughout Intermountain Health and affiliate clinics from October 5, 2020, to January 31, 2021; 30-day readmissions rates in the pharmacist intervention group versus the comparator group were 24/191 (12.57%) versus 511/2526, (20.23%), respectively, yielding a statistically significant difference (P < 0.05). The absolute risk of readmission was reduced by 7.66%, with a number needed to treat of 14. Approximately 14 readmissions were prevented in the pharmacist intervention group, resulting in an estimated cost savings of $212,800 and return on investment of $16.19:1., Conclusion: Pharmacist intervention in the outpatient setting in high-risk TOC patients resulted in decreased 30-day readmission rates and increased cost savings. Further investigation is warranted to identify patient factors where pharmacist intervention is most beneficial., (Copyright © 2023 American Pharmacists Association®. Published by Elsevier Inc.

Background: Rural cancer survivors face a greater number of health disparities, including poorer health-related quality of life (HRQoL), than urban cancer survivors. Engagement in healthy lifestyle behaviors also varies between rural and urban cancer survivors. Lifestyle behaviors can improve HRQoL; however, the combination of behaviors most important for HRQoL in rural survivors is unclear. This study examined clusters of lifestyle behaviors in rural cancer survivors, and differences in HRQoL between behavioral clusters., Methods: Rural cancer survivors in the United States (N = 219) completed a cross-sectional survey. Lifestyle behaviors were classified into unhealthy/healthy binary categories (inactive/active, longer/shorter sedentary time, excessive/acceptable fat intake, very low/higher fruit and vegetable intake, some/no alcohol consumption, and poor/good sleep quality). Behavioral clusters were identified by latent class analysis. HRQoL differences between behavioral clusters were assessed by ordinary least squares regression., Results: The 2-class model demonstrated the best fit and interpretability. The "mostly unhealthy behaviors" class (38.5% of sample) had higher probabilities of all unhealthy behaviors, except alcohol consumption. The "healthier energy balance" class (61.5% of sample) had higher probabilities of active, shorter sedentary, higher fruit and vegetable consumption, excessive fat intake, some alcohol consumption, and poor sleep categories, and reported better HRQoL., Conclusions: Healthier energy balance behaviors were particularly relevant for HRQoL in rural cancer survivors. Multiple behavior change interventions to improve HRQoL in rural cancer survivors should focus on supporting energy balance behaviors. Many rural cancer survivors may lead very unhealthy lifestyles, placing them at high risk of adverse outcomes. This subpopulation should be prioritized to help alleviate cancer health disparities.

Background: Restoration of shoulder function in obstetrical brachial plexus injury is paramount. There remains debate as to the optimal method of upper trunk reconstruction. The purpose of this study was to test the hypothesis that spinal accessory nerve to suprascapular nerve transfer leads to improved shoulder external rotation relative to sural nerve grafting., Methods: A systematic review of Medline, EMBASE, EBSCO CINAHL, SCOPUS, Cochrane Library, and TRIP Pro from inception was conducted. Our primary outcome was shoulder external rotation., Results: Four studies were included. Nerve transfer was associated with greater shoulder external rotation relative to nerve grafting (mean difference: 0.82 AMS 95% confidence interval [CI]: 0.27-1.36, P < .005). Patients undergoing nerve grafting were more likely to undergo a secondary shoulder stabilizing procedure (odds ratio [OR]: 1.27, 95% CI: 0.8376-1.9268)., Conclusion: In obstetrical brachial plexus injury, nerve transfer is associated with improved shoulder external rotation and a lower rate of secondary shoulder surgery., Level of Evidence: Level III; Therapeutic.

Description: In May 2022, leadership within the U.S. Department of Veterans Affairs (VA) and U.S. Department of Defense (DoD) approved a joint clinical practice guideline for the use of opioids when managing chronic pain. This synopsis summarizes the recommendations that the authors believe are the most important to highlight., Methods: In December 2020, the VA/DoD Evidence-Based Practice Work Group assembled a team to update the 2017 VA/DoD Clinical Practice Guideline for Opioid Therapy for Chronic Pain. The guideline development team included clinical stakeholders and conformed to the National Academy of Medicine's tenets for trustworthy clinical practice guidelines. The guideline team developed key questions to guide a systematic evidence review that was done by an independent third party and distilled 20 recommendations for care using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. The guideline team also created 3 one-page algorithms to help guide clinical decision making. This synopsis presents the recommendations and highlights selected recommendations on the basis of clinical relevance., Recommendations: This guideline is intended for clinicians who may be considering opioid therapy to manage patients with chronic pain. This synopsis reviews updated recommendations for the initiation and continuation of opioid therapy; dose, duration, and taper of opioids; screening, assessment, and evaluation; and risk mitigation. New additions are highlighted, including recommendations about the use of buprenorphine instead of full agonist opioids; assessing for behavioral health conditions and factors associated with higher risk for harm, such as pain catastrophizing; and the use of pain and opioid education to reduce the risk for prolonged opioid use for postsurgical pain.

Background: Reverse end-to-side (RETS) nerve transfer has become increasingly popular in patients with severe high ulnar nerve injury, but the reported outcomes have been inconsistent., Objective: To evaluate the "babysitting effect," we compared outcomes after anterior interosseous nerve RETS transfer with nerve decompression alone. To evaluate the source of regenerating axons, a group with end-to-end (ETE) transfer was used for comparisons., Methods: Electrophysiology measures were used to quantify the regeneration of anterior interosseous nerve (AIN) and ulnar nerve fibers while functional recovery was evaluated using key pinch and Semmes-Weinstein monofilaments. The subjects were followed postsurgically for 3 years., Results: Sixty-two subjects (RETS = 25, ETE = 16, and decompression = 21) from 4 centers in Western Canada were enrolled. All subjects with severe ulnar nerve injury had nerve compression at the elbow except 10 in the ETE group had nerve laceration or traction injury. Postsurgically, no reinnervation from the AIN to the abductor digiti minimi muscles was seen in any of the RETS subjects. Although there was no significant improvement in compound muscle action potentials amplitudes and pressure detection thresholds in the decompression and RETS group, key pinch strength significantly improved in the RETS group ( P < .05)., Conclusion: The results from published clinical trials are conflicting in part because crossover regeneration from the donor nerve has never been measured. Unlike those with ETE nerve transfers, we found that there was no crossover regeneration in the RETS group. The extent of reinnervation was also no different from decompression surgery alone. Based on these findings, the justifications for this surgical technique need to be carefully re-evaluated., (Copyright © Congress of Neurological Surgeons 2022. All rights reserved.)

Purpose: To present a case of idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome that was successfully managed with serial intravitreal aflibercept injections., Methods: Ophthalmic imaging and visual acuity were used to monitor disease state and track treatment methods to determine the most valuable combination of treatment medication and treatment interval., Results: A 28-year-old woman with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome status after panretinal photocoagulation of both eyes presented with bilateral cystoid macular edema. We demonstrate successful management of retinal cystoid macular edema associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome using serial intravitreal aflibercept injections., Conclusion: Intravitreal aflibercept has a useful role in managing the potential retinal complications associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome and provides further insights into treatment of the later stages of this rare disease.

Objective: To evaluate personal and economical outcomes of CarbSmart, a 3-hour person-centered, theory-based program implemented throughout Australia, targeting optimal dietary carbohydrate management., Methods: More than 500 CarbSmart programs were implemented over 4.5 years. Pre-, post-, (N = 4656) and 3-month follow-up assessments (N = 188) of knowledge, empowerment, confidence, and patient activation were collected from people with diabetes. Participant satisfaction and potential annual cost-savings were calculated., Findings: Repeated measures ANCOVAs showed large improvements pre- to post-program in all outcome variables (d = 0.80-1.68), which were maintained at 3-month follow-up in a sub-sample. Participant satisfaction was high (Net Promoter Score = 72.3). Potential annual cost-savings nation-wide were estimated at US$512million., Conclusion: This paper provides evidence that CarbSmart is effective in improving behavioral indicators of self-management outcomes in Australians living with diabetes., Practice Implications: CarbSmart has the potential to prevent diabetes-related complications. However, not engaging people living with diabetes with lower levels of patient activation at baseline was recognized as a future opportunity to improve the impact of our service. Strategies are needed to engage people with lower activation levels to improve outcomes in vulnerable and at-risk populations., Funding: The development of CarbSmart was funded by Diabetes WA, the national implementation of CarbSmart by the National Diabetes Services Scheme, an initiative of the Australian Government., (Copyright © 2022.

Objective: This process evaluation aimed to evaluate the feasibility and acceptability of Aussie-FIT, a group-based weight loss intervention for men with overweight and obesity in Australia., Design: Process data and data collected from: (1) six-participant focus groups ( n = 24), (2) coach interviews ( n  = 4), (3) audio recordings of Aussie-FIT sessions and (4) post-program participant surveys ( n = 93) were analysed., Main Outcome Measures: We explored the feasibility and acceptability of program setting and context, recruitment strategies, factors impacting implementation and mechanisms of impact., Results: Recruitment via Australian Football League (AFL) clubs was highly effective; 426 men expressed interest within 3 days of advertising, 130 men took part. Program attendance was not consistently recorded by coaches. Coach interviews indicated a 'core group of men' participated in each session (typically 10-12 of 15 men). Program delivery proved feasible in the AFL context. Program acceptability and satisfaction were high. Internalisation of autonomous motives was identified as driving behaviour change. Behaviour change to support maintained weight loss was facilitated through habit formation, goal setting and effective management of multiple goals., Conclusion: Aussie-FIT sets a blueprint for future weight loss interventions that utilise behaviour change strategies and principles of self-determined motivation to support men to lose weight., Trial Registration: Australian New Zealand Clinical Trials Registry: ACTRN12617000515392., © 2021 Informa UK Limited, trading as Taylor & Francis Group.

Background: Bronchial thermoplasty is a device-based treatment for subjects ≥ 18 years of age with severe asthma poorly controlled with inhaled corticosteroids and long-acting beta-agonists. The Post-FDA Approval Clinical Trial Evaluating Bronchial Thermoplasty in Severe Persistent Asthma (PAS2) study collected data on patients with severe asthma undergoing this procedure., Research Question: What are the 5-year efficacy and safety results in patients with severe asthma who have undergone bronchial thermoplasty?, Study Design and Methods: This was a prospective, open-label, observational, multicenter study conducted in the United States and Canada. Subjects 18 to 65 years of age who were taking inhaled corticosteroids ≥ 1,000 μg/d (beclomethasone or equivalent) and long-acting beta-agonists ≥ 80 μg/d (salmeterol or equivalent) were included. Severe exacerbations, hospitalization, ED visits, and medication usage were evaluated for the 12 months prior to and at years 1 through 5 posttreatment. Spirometry was evaluated at baseline and at years 1 through 5 posttreatment., Results: A total of 284 subjects were enrolled at 27 centers; 227 subjects (80%) completed 5 years of follow-up. By year 5 posttreatment, the proportion of subjects with severe exacerbations, ED visits, and hospitalizations was 42.7%, 7.9%, and 4.8%, respectively, compared with 77.8%, 29.4%, and 16.1% in the 12 months prior to treatment. The proportion of subjects on maintenance oral corticosteroids decreased from 19.4% at baseline to 9.7% at 5 years. Analyses of subgroups based on baseline clinical and biomarker characteristics revealed a statistically significant clinical improvement among all subgroups., Interpretation: Five years after treatment, subjects experienced decreases in severe exacerbations, hospitalizations, ED visits, and corticosteroid exposure. All subgroups demonstrated clinically significant improvement, suggesting that bronchial thermoplasty improves asthma control in different asthma phenotypes., Clinical Trial Registration: ClinicalTrials.gov; No.: NCT01350336; URL: www., Clinicaltrials: gov., (Copyright © 2021 American College of Chest Physicians.

Background: The aim of this work was to develop a National Evaluation Framework to facilitate the standardization of delivery, quality, reporting, and evaluation of diabetes education and support programs delivered throughout Australia through the National Diabetes Services Scheme (NDSS). The NDSS is funded by the Australian Government, and provides access to diabetes information, education, support, and subsidized product across diverse settings in each state and territory of Australia through seven independent service-providers. This article reports the approach undertaken to develop the Framework., Methods: A participatory approach was undertaken, focused on adopting nationally consistent outcomes and indicators, nominating objectives and measurement tools, specifying evaluation processes, and developing quality standards. Existing programs were classified based on related, overarching indicators enabling the adoption of a tiered system of evaluation., Results: Two outcomes (i.e., improved clinical, reduced cost) and four indicators (i.e., improved knowledge and understanding, self-management, self-determination, psychosocial adjustment) were adopted from the Eigenmann and Colagiuri national consensus position statement for diabetes education. This allowed for the identification of objectives (i.e., improved empowerment, reduced distress, autonomy supportive program delivery, consumer satisfaction) and related measurement instruments. Programs were categorized as comprehensive, topic-specific, or basic education, with comprehensive programs allocated to receive the highest-level of evaluation. Eight quality standards were developed, with existing programs tested against those standards. Based on the results of testing, two comprehensive (OzDAFNE for people with type 1 diabetes, DESMOND for people with type 2 diabetes), and eight topic-specific (CarbSmart, ShopSmart, MonitorSmart, FootSmart, MedSmart, Living with Insulin, Insulin Pump Workshop, Ready Set Go - Let's Move) structured diabetes self-management education and support programs were nominated for national delivery., Conclusions: The National Evaluation Framework has facilitated consistency of program quality, delivery, and evaluation of programs delivered by multiple service providers across diverse contexts. The Framework could be applied by other service providers who facilitate multiple diabetes education and support programs and could be adapted for use in other chronic disease populations where education and support are indicated., (© 2022.

This qualitative research explored older adults' perceptions of participating in group-based walking programs set in independent-living retirement village contexts. Semistructured interviews were conducted with a subset of participants from the Residents in Action Trial. Data were analyzed through a combination of deductive and inductive thematic analysis. Findings were interpreted from a social identity perspective. Five themes were identified: (a) varying levels of social cohesion in retirement villages; (b) degree of shared identity between residents; (c) health, mobility, and preferred pace; (d) devotion to spouse; and (e) busy lives. When designing group-based walking interventions in retirement villages, it is important to consider community-level social cohesion and degree of relatedness between village residents. When attempting to build a sense of shared identity and relatedness between group members, researchers and policy makers should consider differing backgrounds, capabilities, schedules, and interests of participants.

Case: The reconstruction of large nerve gaps remains a reconstructive challenge. Here, we present a case report of brachial plexus reconstruction using nerve grafts harvested as spare parts from an amputated limb. It also allowed us to use motor nerve grafts to reconstruct defects in the posterior cord and musculocutaneous nerve. The patient recovered good shoulder and elbow function at 2.5 years with evidence of innervation distally on electromyography., Conclusion: Spare part surgery should always be kept in a surgeons' reconstructive algorithm. Reconstruction of large nerve gaps can be achieved with autologous nerve grafts in certain circumstances., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/B470)., (Copyright © 2021 by The Journal of Bone and Joint Surgery, Incorporated.)

Background: Although there was initial success using tibial nerve transfer to restore ankle dorsiflexion following peroneal nerve injury, results from later series were less promising. A potential reason is coactivation of the much stronger antagonistic muscles during gait. The purpose of this study was to test the hypothesis that gait training would improve functional performance following tibial nerve transfer., Methods: Using a prospective, nonrandomized, controlled study design, patients were divided into two groups: surgery only or surgery plus gait training. Of the 20 patients who showed reinnervation in the tibialis anterior muscle, 10 were assigned to the gait training group, and an equal number were in the control group. Those in the treatment group began training once reinnervation in the tibialis anterior muscle was detected, whereas those in the control group continued to use their ankle-foot orthosis full time. Differences in ankle dorsiflexion were measured using the Medical Research Council scale, and quantitative force measurement and functional disability was measured using the Stanmore Scale., Results: Patients in the gait training group attained significantly better functional recovery as measured by the Stanmore Scale (79.5 ± 14.3) (mean ± SD) versus (37.2 ± 3.5) in the control group (p = 0.02). Medical Research Council grades were 3.8 ± 0.6 in the training group versus 2.5 ± 1.2 in the surgery only group (p < 0.05). Average dorsiflexion force from patients with above antigravity strength (all from the training group) was 31 percent of the contralateral side., Conclusion: In patients with successful reinnervation following tibial nerve transfers, rehabilitation training significantly improved dorsiflexion strength and function., Clinical Question/level of Evidence: Therapeutic, II., (Copyright © 2021 by the American Society of Plastic Surgeons.)

Background: Bronchial thermoplasty is an endoscopic treatment for uncontrolled asthma. Previous randomised clinical trials have shown that bronchial thermoplasty reduces severe exacerbations in people with asthma. However, the long-term efficacy and safety of bronchial thermoplasty beyond 5 years is unknown. The BT10+ study aimed to investigate the efficacy and safety of bronchial thermoplasty after 10 or more years of follow-up., Methods: BT10+ was an international, multicentre, follow-up study of participants who were previously enrolled in the AIR, RISA, and AIR2 trials and who had 10 or more years of follow-up since bronchial thermoplasty treatment. Data on patient demographics, quality of life, lung function, CT scans (AIR2 participants only), severe exacerbations, and health-care use during the previous year were collected at the BT10+ 10-year outcomes study visit. The primary effectiveness endpoint was durability of the thermoplasty treatment effect, determined by comparing the proportion of participants who had severe exacerbations during the first and fifth years after bronchial thermoplasty treatment with the proportion of participants who had severe exacerbations during the 12-month period before the BT10+ visit. The primary safety endpoint was the absence of clinically significant post-treatment respiratory image changes after bronchial thermoplasty, defined as bronchiectasis or bronchial stenosis as confirmed by pulmonary volumetric high-resolution CT scan at the BT10+ visit (AIR2 participants only). All analyses were done on an intention-to-treat basis. The trial is registered with ClinicalTrials.gov, NCT03243292. The last patient was enrolled on Dec 11, 2018. The last patient completed follow-up on Jan 10, 2019., Findings: The BT10+ study enrolled 192 (45%) of the 429 participants who were enrolled in the AIR, RISA, and AIR2 trials. The BT10+ participants comprised 136 who received bronchial thermoplasty (52% of the 260 participants who received bronchial thermoplasty in the original trials), and 56 sham or control participants (33% of 169 from the original trials). 18 (32%) sham or control participants received bronchial thermoplasty after the previous trials concluded. The participants included in BT10+ were followed for 10·8-15·6 years (median 12·1 years) post-treatment. Baseline characteristics were similar between participants enrolled in BT10+ and those not enrolled. Participants treated with bronchial thermoplasty had similar proportions of severe exacerbations at the BT10+ visit (34 [25%] of 136 participants) compared with 1 year (33 [24%] of 135 participants; difference 0·6%, 95% CI -9·7 to 10·8) and 5 years (28 [22%] of 130 participants; difference 3·5%, -6·7% to 13·6) after treatment. Quality of life measurements and spirometry were similar between year 1, year 5, and the BT10+ visit. At the BT10+ study visit, pulmonary high-resolution CT scans from AIR2 participants treated with bronchial thermoplasty showed that 13 (13%) of 97 participants had bronchiectasis. When compared with baseline high-resolution CT scans, six (7%) of 89 participants treated with bronchial thermoplasty who did not have bronchiectasis at baseline had developed bronchiectasis after treatment (5 classified as mild, 1 classified as moderate). Participants treated with bronchial thermoplasty after the original study and participants in the sham or control group also had reductions in severe exacerbations at the BT10+ visit compared with baseline., Interpretation: Our findings suggest that efficacy of bronchial thermoplasty is sustained for 10 years or more, with an acceptable safety profile. Therefore, bronchial thermoplasty is a long-acting therapeutic option for patients with asthma that remains uncontrolled despite optimised medical treatment., Funding: Boston Scientific., (Copyright © 2021 Elsevier Ltd.

Elevated intraocular levels of angiogenic cytokines such as vascular endothelial growth factor (VEGF) have been implicated the development of diabetic retinopathy. Over a decade of clinical evidence shows intravitreal injection of anti-VEGF agents is associated with decreased disease progression and preservation of vision. However, the treatment burden associated with monthly injections limits the effectiveness of existing anti-VEGF therapies. Current research has focused on sustained treatment paradigms such as longer acting drugs, drug delivery implants, and gene therapy. In this study, we tested a novel approach by dialyzing proteins from the vitreous using bioceramic implant composed of hydroxyapatite. Preliminary in vitro and in vivo studies demonstrate a high affinity and capacity for VEGF absorption. After three months implantation in New Zealand White Cross rabbits, the hydroxyapatite demonstrated good biocompatibility with no inflammation and normal retinal physiology and histology. These studies demonstrate that prolonged VEGF suppression intraocularly may be accomplished with a bioceramic implant., (Copyright © 2020. Published by Elsevier Ltd.)

Background: Recent evidence shows that sport settings can act as a powerful draw to engage men in weight loss. The primary objective of this pilot study was to test the feasibility of delivering and to evaluate preliminary efficacy of Aussie-FIT, a weight-loss program for men with overweight/obesity delivered in Australian Football League (AFL) settings, in preparation for a future definitive trial., Methods and Findings: This 6-month pilot trial took place in Perth, Australia. Participants were overweight/obese (Body Mass Index [BMI] ≥ 28 kg/m2), middle-aged (35-65 years old) men. Participants were recruited in May 2018, and the intervention took place between June and December 2018. The intervention involved 12 weekly 90-min face-to-face sessions, incorporating physical activity, nutrition, and behaviour change information and practical activities delivered by coaches at 2 clubs. Data were collected at baseline and immediately postintervention. For trial feasibility purposes, 6-month follow-ups were completed. Outcomes were differences in weight loss (primary outcome) and recruitment and retention rates, self-reported measures (for example, psychological well-being), device-measured physical activity, waist size, and blood pressure at 3 months. Within 3 days of advertising at each club, 426 men registered interest; 306 (72%) were eligible. Men were selected on a first-come first-served basis (n = 130; M age = 45.8, SD = 8; M BMI = 34.48 kg/m2, SD = 4.87) and randomised by a blinded researcher. Trial retention was 86% and 63% at 3- and 6-month follow-ups (respectively). No adverse events were reported. At 3 months, mean difference in weight between groups, adjusted for baseline weight and group, was 3.3 kg (95% CI 1.9, 4.8) in favour of the intervention group (p < 0.001). The intervention group's moderate-to-vigorous physical activity (MVPA) was higher than the control group by 8.54 min/day (95% CI 1.37, 15.71, p = 0.02). MVPA among men attracted to Aussie-FIT was high at baseline (intervention arm 35.61 min/day, control arm 38.38 min/day), which may have limited the scope for improvement., Conclusions: Aussie-FIT was feasible to deliver; participants increased physical activity, decreased weight, and reported improvements in other outcomes. Issues with retention were a limitation of this trial. In a future, fully powered randomised controlled trial (RCT), retention could be improved by conducting assessments outside of holiday seasons., Trial Registration: Australian New Zealand Clinical Trials Registry: ACTRN12617000515392., Competing Interests: The authors have declared that no competing interests exist.

Age-related macular degeneration (AMD) is one of the leading causes of blindness in the industrialized world, affecting over 8 million patients in the United State alone. While the wet (exudative) form of the disease is treated with intraocular injections, there are currently no approved therapies available for the dry (non-exudative) form of the disease which often affects both eyes in patients with AMD. Current research has focused on developing drugs that can be injected into the eye, but the treatment burden associated with monthly injections limits the effectiveness of this approach. Hence, there is a pressing need for a long-term therapeutic solution for patients suffering from this blinding disease. We detail a novel implantable intraocular device, which adsorbs and traps complement factors associated with AMD. In this study, we tested a novel approach by dialyzing proteins from the vitreous using biocompatible implants composed of a nanopore polyacrylonitrile polymer membrane. Preliminary in vitro and in vivo studies demonstrate a high affinity and capacity for complement protein absorption. After a three-month implantation in New Zealand White Cross rabbits, the implant demonstrated good biocompatibility with no inflammation and normal retinal physiology and histology. These studies demonstrate that prolonged CF suppression intraocularly may be accomplished with a nanopore polymer membrane.

Background: Given the substantive health inequalities in peri-urban communities and the potential for physical activity to promote health in these communities, identifying modifiable physical activity determinants in this population is important. This study explored effects of the peri-urban environment and psychological constructs on physical activity intentions and behavioural automaticity guided by an integrated theoretical framework., Methods: Peri-urban Australians (N = 271) completed self-report measures of environmental (i.e. physical/social environment, and neighbourhood selection), motivational (i.e. autonomous motivation), and social cognition (i.e. attitudes, norms, and perceived behavioural control [PBC]) constructs, past behaviour, intentions, and automaticity., Results: A well-fitting path analytic model revealed that: autonomous motivation predicted all social cognition constructs; subjective norms and PBC, but not attitudes; autonomous motivation predicted intentions and automaticity; and subjective norms and PBC mediated effects of autonomous motivation on intentions. Of the environmental constructs, only neighbourhood selection was related to intentions, mediated by PBC., Conclusions: Autonomous motivation is an important correlate of physical activity intentions and automaticity, and subjective norms and PBC also related to intentions. Individuals perceiving a supportive environment were more likely to report positive PBC and intentions. Targeting change in autonomous motivation, and normative and control beliefs may help enhance physical activity intentions and automaticity in peri-urban communities., (© 2019 The International Association of Applied Psychology.)

Background: Patients with severe cubital tunnel syndrome often have poor functional recovery with conventional surgical treatment. Postsurgical electrical stimulation (PES) has been shown to enhance axonal regeneration in animal and human studies., Objective: To determine if PES following surgery for severe cubital tunnel syndrome would result in better outcomes compared to surgery alone., Methods: Patients with severe cubital tunnel syndrome in this randomized, double-blind, placebo-controlled trial were randomized in a 1:2 ratio to the control or stimulation groups. Control patients received cubital tunnel surgery and sham stimulation, whereas patients in the stimulation group received 1-h of 20 Hz PES following surgery. Patients were assessed by a blinded evaluator annually for 3 yr. The primary outcome was motor unit number estimation (MUNE) and secondary outcomes were grip and key pinch strength and McGowan grade and compound muscle action potential., Results: A total of 31 patients were enrolled: 11 received surgery alone and 20 received surgery and PES. Three years following surgery, MUNE was significantly higher in the PES group (176 ± 23, mean + SE) compared to controls (88 ± 11, P < .05). The mean gain in key pinch strength in the PES group was almost 3 times greater than in the controls (P < .05). Similarly, other functional and physiological outcomes showed significantly greater improvements in the PES group., Conclusion: PES enhanced muscle reinnervation and functional recovery following surgery for severe cubital tunnel syndrome. It may be a clinically useful adjunct to surgery for severe ulnar neuropathy, in which functional recovery with conventional treatment is often suboptimal., (Copyright © 2019 by the Congress of Neurological Surgeons.)

Issue Addressed: Residents of peri-urban Australia face health inequalities compared to city dwellers. Active lifestyles provide many benefits that could improve the health of this population; however, peri-urban Australians are more likely to be inactive and sedentary. The aim of this study was to identify the physical activity and sedentary behaviour-related beliefs of peri-urban Australians., Methods: Semi-structured interviews were undertaken with adult residents of peri-urban, southern Queensland. Participants (N = 8) were recruited from a related study, purposefully selected to ensure diversity. Data were analysed by thematic analysis. Interviews were conducted until data and inductive-thematic saturation were reached., Results: Three themes were identified, representing beliefs about intrapersonal, interpersonal/socio-cultural and physical environmental factors relevant to active lifestyles among peri-urban Australians. Active lifestyle behaviours were perceived as beneficial for health. Social interaction was described as an important outcome of physical activity. Features of the physical environment negatively impacted the perceived difficulty of performing physical activity and avoiding sedentary behaviour., Conclusions: Active lifestyle strategies that support social interaction through physical activity and participation in sports may be particularly useful in peri-urban environments where opportunities for social interaction are limited. Such strategies should also take into account contextual factors that negatively impact active lifestyle control beliefs (eg, distance). SO WHAT?: This study provides insight into factors that may influence the active lifestyles of peri-urban Australians. This information can be used to develop contextually relevant strategies designed to encourage physical activity, discourage sedentary behaviour and assist to relieve health disparities faced by this population., (© 2019 Australian Health Promotion Association.)

Purpose: To evaluate levels of complement factors in human vitreous of eyes with retinal detachments (RDs) and proliferative diabetic retinopathy (PDR) eyes., Methods: Human vitreous samples were collected from eyes undergoing routine vitrectomy at the University of Colorado Health Eye Center (Aurora, CO). Complement factor D, component C5/C5a, and component C9 levels were measured using enzyme-linked immunosorbent assay and multiplex assays. Retinal detachment and PDR eyes were compared with controls, which were defined as eyes with macular holes or epiretinal membranes., Results: The levels of complement factor D in PDR (mean = 2,110.0 ng/mL, P = 0.001) and RD (mean = 660.9 ng/mL, P = 0.03) eyes were statistically significantly higher than controls (mean = 290.5 ng/mL). The levels of complement component C9 were also more elevated in PDR (P = 0.004) compared with control but not in RD eyes., Conclusion: Elevated complement factors, particularly of the alternative pathway, were noted in PDR and RD eyes compared with controls. One potential explanation for this is that the oxidative stress in RD and PDR eyes leads to complement dysregulation and alternative complement upregulation.

Background: In order to increase one's competitiveness in the current job market, Canadian plastic surgery graduates may complete additional degrees and multiple fellowships. The authors sought to determine the impact of this additional training on the practice profile of recent graduates and determine the current state of job satisfaction among this group., Methods: An anonymous cross-sectional online survey was created and sent to all 250 graduates of Canadian plastic surgery residencies from 2005 to 2015. Demographics were collected and questions grouped into clinical, teaching, research, and administrative components. Questions pertaining to job satisfaction were also included., Results: The response rate to the survey was 39%. Sixty-nine (71%) respondents had permanent attending positions at the time of survey completion, while the remaining 28 respondents did not. Among those with permanent positions, 59 (86%) completed at least one fellowship and 30 (43%) have an advanced degree. Of those who did fellowship training, 76% practice primarily in their area of subspecialty. Having an advanced degree showed a trend to a higher percentage of practice dedicated to research (5.6% vs 1.9%; P = .074) and more publications per year were seen among this group (1.31 vs 0.30; P = .028). Eighty-six percent of respondents are satisfied with their current attending position., Conclusions: The majority of recent Canadian plastic surgery graduates are undergoing fellowship training and are practicing primarily in their fields of subspecialty training. Having a postgraduate degree was associated with a higher number of publications per year as an attending surgeon. Job satisfaction is high among recent graduates., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Issue Addressed: Australians living in peri-urban areas are insufficiently active, sedentary and experience poorer health than people in major cities. There are health benefits attributable to active lifestyles that could contribute to the improved health and well-being of this population. To support the adoption of active lifestyles, it is important to understand the unique context in which behaviour occurs., Methods: The aim of this study was to identify characteristics of the social and physical peri-urban environment that may impact active lifestyles. Semi-structured interviews were conducted in peri-urban southern Queensland. Data were analysed by thematic analysis., Results: The natural environment, weather, distance, accessibility and walkability were features of the physical environment relevant to active lifestyles. Social factors included social capital and crime. Activity-supportive characteristics (eg, community spirit) were identified, in addition to active lifestyle barriers (eg, lack of public transport)., Conclusions: Despite activity-supportive social and environmental characteristics, most participants reported inactive lifestyles. The barriers to active lifestyles in peri-urban environments may negate these activity-supportive features. Some barriers are difficult to modify (eg, distance and accessibility). However, some may be alleviated through the adoption of activity-supportive policy and urban design (eg, pedestrian mobility infrastructure). SO WHAT?: Strategies to support active lifestyles in peri-urban environments must take into account unmodifiable contextual barriers, whilst encouraging utilisation of existing activity-supportive infrastructure and resources. The enhancement of activity-supportive environments through improved neighbourhood walkability and the usability of public transport may encourage some peri-urban residents to undertake more active forms of transport and recreational physical activity., (© 2018 Australian Health Promotion Association.)

Purpose: To study new and existing risk factors related to age-related macular degeneration (AMD) phenotypes in a Colorado cohort., Methods: Age-related macular degeneration was categorized into early, intermediate, or advanced forms. Controls (n = 180) were patients with cataract and no AMD. Demographic and clinical data were gathered by patient interview and verified by chart review. Image data were reviewed by vitreoretinal specialists. Statistical analysis included univariable and multivariate logistic regression analysis (P < 0.05)., Results: Among the 456 patients with AMD, 157 (34.4%), 80 (17.6%), and 219 (48.0%) had the early/intermediate, geographic atrophy, and neovascular forms of the disease, respectively. Adjusted for age, African-American race was associated with a reduced risk of early/intermediate (adjusted odds ratio [AOR] = 0.08, confidence interval [CI] = 0.01-0.67) and neovascular AMD (AOR = 0.15, CI = 0.03-0.72). A family history of AMD was a risk factor for early/intermediate (AOR = 4.08, CI = 2.30-7.25), geographic atrophy (AOR = 8.62, CI = 3.77-19.7), and neovascular AMD (AOR = 3.76, CI = 2.16-6.56). A history of asthma was related to the early/intermediate form of AMD (AOR = 2.34, CI = 1.22-4.46)., Conclusion: Studying AMD in specific populations may reveal novel risk factors such as our finding of a relationship between asthma history and AMD.

Background: Carpal tunnel syndrome is very common. Although surgery is effective in mild and moderate cases, recovery is often incomplete in severe cases. Therefore, adjuvant therapy to improve nerve regeneration in those patients is much needed. Acetyl-L-carnitine has been shown to be effective in other neuropathies. The goal of this study is to test the hypothesis that acetyl-L-carnitine can promote nerve regeneration and improve function in patients with severe carpal tunnel syndrome., Methods: In this proof-of-principle, double-blind, randomized, placebo-controlled trial, adults with severe carpal tunnel syndrome were randomized to receive 3000 mg/day of acetyl-L-carnitine orally or placebo following carpal tunnel release surgery for 2 months. Outcomes were assessed at baseline and at 3, 6, and 12 months postoperatively. Symptom severity and functional outcomes were assessed using the Boston Carpal Tunnel Questionnaire and a wide range of physiologic and functional outcome measures. Patient safety was monitored by physical examination, blood work, and serum drug levels. The outcomes were analyzed using repeated measure two-way analysis of variance., Results: Twenty patients with similar baseline characteristics were assigned randomly to the treatment or placebo group in a 1:1 ratio. Sixty percent were women with a mean age ± SD of 59 ± 2. The treatment was safe with no major adverse events reported. Although patients in both groups showed improvements postoperatively, there was no significant difference in any of the outcome measures between the groups., Conclusion: Although acetyl-L-carnitine was well tolerated, it did not improve nerve regeneration or functional recovery in patients with severe carpal tunnel syndrome., Clinical Question/level of Evidence: Therapeutic, II.

Background: Outcomes for pancreatic resection have been studied extensively due to the high morbidity and mortality rates, with high-volume centers achieving superior outcomes. Ongoing investigations include healthcare costs, given the national focus on reducing expenditures. Therefore, we sought to evaluate the relationships between pancreatic surgery costs with perioperative outcomes and volume status., Methods: We performed a retrospective analysis of 27,653 patients who underwent elective pancreatic resections from October 2013 to June 2017 using the Vizient database. Costs were calculated from charges using cost-charge ratios and adjusted for geographic variation. Generalized linear modeling adjusting for demographic, clinical, and operation characteristics was performed to assess the relationships between cost and length of stay, complications, in-hospital mortality, readmissions, and hospital volume. High-volume centers were defined as hospitals performing ≥ 19 operations annually., Results: The unadjusted mean cost for pancreatic resection and corresponding hospitalization was $20,352. There were no differences in mean costs for pancreatectomies performed at high- and low-volume centers [- $1175, 95% confidence interval (CI) - $3254 to $904, p = 0.27]. In subgroup analysis comparing adjusted mean costs at high- and low-volume centers, there was no difference among patients without an adverse outcome (- $99, 95% CI - $1612 to 1414, p = 0.90), one or more adverse outcomes (- $1586, 95% CI - $4771 to 1599, p = 0.33), or one or more complications (- $2835, 95% CI - $7588 to 1919, p = 0.24)., Conclusions: While high-volume hospitals have fewer adverse outcomes, there is no relationship between surgical volume and costs, which suggests that, in itself, surgical volume is not an indicator of improved healthcare efficiency reflected by lower costs. Patient referral to high-volume centers may not reduce overall healthcare expenditures for pancreatic operations.
