The Effect of Chronic Altitude Exposure on COPD Outcomes in the SPIROMICS Cohort.

RATIONALE: Individuals with COPD have airflow obstruction and maldistribution of ventilation. For those living at high altitude, any gas exchange abnormality is compounded by reduced partial pressures of inspired oxygen. OBJECTIVES: Does residence at higher-altitude exposure affect COPD outcomes, including lung function, imaging characteristics, symptoms, health status, functional exercise capacity, exacerbations, or mortality? METHODS: From the SPIROMICS cohort, we identified individuals with COPD living below 1,000 ft (305 m) elevation (n= 1,367) versus above 4,000 ft (1,219 m) elevation (n= 288). Multivariable regression models were used to evaluate associations of exposure to high altitude with COPD-related outcomes. MEASUREMENTS AND MAIN RESULTS: Living at higher altitude was associated with reduced functional exercise capacity as defined by 6MWD (-32.3 m, (-55.7 to -28.6)). There were no differences in patient-reported outcomes as defined by symptoms (CAT, mMRC), or health status (SGRQ). Higher altitude was not associated with a different rate of FEV1 decline. Higher altitude was associated with lower odds of severe exacerbations (IRR 0.65, (0.46 to 0.90)). There were no differences in small airway disease, air trapping, or emphysema. In longitudinal analyses, higher altitude was associated with increased mortality (HR 1.25, (1.0 to 1.55)); however, this association was no longer significant when accounting for air pollution. CONCLUSIONS: Chronic altitude exposure is associated with reduced functional exercise capacity in individuals with COPD, but this did not translate into differences in symptoms or health status. Additionally, chronic high-altitude exposure did not affect progression of disease as defined by longitudinal changes in spirometry.

Patient-centered research in pediatric transplant: Engaging families and recipients.

Pediatric liver transplant (LT) recipients navigate a lifelong journey that includes constant monitoring and challenges. Research priorities and questions in LT have traditionally been provider-driven. This project was a novel partnership between a learning health system dedicated to pediatric LT (Starzl Network for Excellence in Pediatric Transplantation) and a parent-led advocacy group (Transplant Families) that aimed to prepare families and providers for collaborative patient-centered outcomes research (PCOR). We developed 5 virtual modules to (1) teach participants about PCOR, and (2) elicit ideas for PCOR priorities and processes in pediatric LT. Parents and providers participated via self-guided online modules or focus groups. Participants included 240 patient partners and 133 pediatric LT providers from 16 centers over 2 years. We held 20 focus groups, including 5 to amplify underrepresented voices: young adults, Spanish speakers, and African Americans. Feedback was summarized to create a PCOR Roadmap, a guide for future PCOR in the Starzl Network, which was disseminated back to participants online and via webinars. Feedback from a diverse group of stakeholders allowed us to develop PCOR priorities and processes for the pediatric LT community. Our engagement strategies could be adapted by other transplant communities to facilitate patient and provider research partnerships.

Surgeon Perspectives on the Management of Aborted Cancer Surgery: Results of a Society of Surgical Oncology Member Survey.

BACKGROUND: While surgery is generally necessary for most solid-organ cancers, curative-intent resection is occasionally aborted due to unanticipated unresectability or occult metastases. Following aborted cancer surgery (ACS), patients have unique and complex care needs and yet little is known about the optimal approach to their management. OBJECTIVE: The aim of this study was to define the practice patterns and perspectives of an international cohort of cancer surgeons on the management of ACS. METHODS: A validated survey assessing surgeon perspectives on patient care needs and management following ACS was developed. The survey was distributed electronically to members of the Society of Surgical Oncology (SSO). RESULTS: Among 190 participating surgeons, mean age was 49 ± 11 years, 69% were male, 61% worked at an academic institution, and most had a clinical practice focused on liver/pancreas (30%), breast (23%), or melanoma/sarcoma cancers (20%). Participants estimated that ACS occurred in 7 ± 6% of their cancer operations, most often due to occult metastases (67%) or local unresectability (30%). Most surgeons felt (very) comfortable addressing their patients' surgical needs (92%) and cancer treatment-related questions (90%), but fewer expressed comfort addressing psychosocial needs (83%) or symptom-control needs (69%). While they perceived discussing next available therapies as the patients' most important priority after ACS, surgeons reported avoiding postoperative complications as their most important priority (p < 0.001). While 61% and 27% reported utilizing palliative care and psychosocial oncology, respectively, in these situations, 46% noted care coordination as a barrier to addressing patient care needs. CONCLUSIONS: Results from this SSO member survey suggest that ACS is relatively common and associated with unique patient care needs. Surgeons may feel less comfortable assessing psychosocial and symptom-control needs, highlighting the need for novel patient-centered approaches.

Overview of the 2023 FDA Circulatory System Devices Advisory Panel meeting on the Recor Paradise Ultrasound-Based Renal Denervation System.

Hypertension continues to be a prominent, avoidable factor contributing to major vascular issues on a global scale. Even with lifestyle adjustments and more aggressive medical treatments, maintaining optimal blood pressure levels remains challenging. This challenge has driven the emergence of device-oriented approaches to address hypertension. To assess the safety and efficacy of the Recor Paradise Ultrasound Renal Denervation System, the Circulatory System Devices Panel was convened by the US Food and Drug Administration (FDA). This manuscript provides a condensed overview of the information put forth by the sponsor and the FDA, along with an account of the considerations and conversations that took place during the meeting.

Recommendations for assessing appearance concerns related to plexiform and cutaneous neurofibromas in neurofibromatosis 1 clinical trials.

BACKGROUND/AIMS: Individuals with neurofibromatosis 1 may experience changes in their appearance due to physical manifestations of the disorders and/or treatment sequelae. Appearance concerns related to these physical changes can lead to psychological distress and poorer quality of life. While many neurofibromatosis 1 clinical trials focus on assessing changes in tumor volume, evaluating patients' perspectives on corresponding changes in symptoms such as physical appearance can be key secondary outcomes. We aimed to determine whether any existing patient-reported outcome measures are appropriate for evaluating changes in appearance concerns within neurofibromatosis 1 clinical trials. METHODS: After updating our previously published systematic review process, we used it to identify and rate existing patient-reported outcome measures related to disfigurement and appearance. Using a systematic literature search and initial triage process, we focused on identifying patient-reported outcome measures that could be used to evaluate changes in appearance concerns in plexiform or cutaneous neurofibroma clinical trials in neurofibromatosis 1. Our revised Patient-Reported Outcome Rating and Acceptance Tool for Endpoints then was used to evaluate each published patient-reported outcome measures in five domains, including (1) respondent characteristics, (2) content validity, (3) scoring format and interpretability, (4) psychometric data, and (5) feasibility. The highest-rated patient-reported outcome measures were then re-reviewed in a side-by-side comparison to generate a final consensus recommendation. RESULTS: Eleven measures assessing appearance concerns were reviewed and rated; no measures were explicitly designed to assess appearance concerns related to neurofibromatosis 1. The FACE-Q Craniofacial Module-Appearance Distress scale was the top-rated measure for potential use in neurofibromatosis 1 clinical trials. Strengths of the measure included that it was rigorously developed, included individuals with neurofibromatosis 1 in the validation sample, was applicable to children and adults, covered item topics deemed important by neurofibromatosis 1 patient representatives, exhibited good psychometric properties, and was feasible for use in neurofibromatosis 1 trials. Limitations included a lack of validation in older adults, no published information regarding sensitivity to change in clinical trials, and limited availability in languages other than English. CONCLUSION: The Response Evaluation in Neurofibromatosis and Schwannomatosis patient-reported outcome working group currently recommends the FACE-Q Craniofacial Module Appearance Distress scale to evaluate patient-reported changes in appearance concerns in clinical trials for neurofibromatosis 1-related plexiform or cutaneous neurofibromas. Additional research is needed to validate this measure in people with neurofibromatosis 1, including older adults and those with tumors in various body locations, and explore the effects of nontumor manifestations on appearance concerns in people with neurofibromatosis 1 and schwannomatosis.

A cluster randomized controlled trial comparing the effectiveness of two school-based interventions for autistic youth with anxiety.

BACKGROUND: Recent systematic reviews have indicated that cognitive behavioral therapy (CBT) is effective in reducing anxiety symptoms for autistic and non-autistic children. However, the vast majority of CBT research for autistic youth has been implemented within university settings and primarily by mental health providers. Schools hold great promise to equitably manage the mental health symptoms of autistic youth. Although preliminary research evaluating CBT within schools has been promising, CBT has not yet been compared to another readily available school mental health program. The goal of this protocol paper is to describe a multi-site study comparing two school-based interventions, Facing Your Fears-School Based (FYF-SB) and Zones of Regulation (ZOR) via a cluster randomized controlled type 1 hybrid effectiveness-implementation trial to determine which of the two interventions will best support autistic youth with anxiety in schools. METHODS: Up to 100 elementary and middle schools will be randomized into FYF-SB or ZOR. Once schools are randomized, a minimum of two interdisciplinary school providers at each school will be trained to deliver either FYF-SB or ZOR over the course of 12 weeks to groups of 2-5 autistic students ages 8-14 years. Over the course of two years, a total of 200 autistic students will receive either ZOR or FYF-SB. The primary outcome of this trial is child anxiety, as rated by masked evaluators and via caregiver- and student-report, which will be measured at baseline, post-treatment, and 6-month follow-up. Semi-structured interviews will also be conducted with a purposive sample of students, caregivers, and school providers to understand the acceptability, appropriateness, and feasibility of either ZOR or FYF-SB. Stakeholder engagement is a central component of this project via two stakeholder advisory boards that will directly inform and oversee the project. DISCUSSION: Results of this study will provide evidence about the relative impact of two school-based mental health interventions on outcomes reported as meaningful by caregivers and school providers. The additional focus on evaluating factors that support the implementation of FYF-SB and ZOR will allow future studies to test targeted implementation strategies that support mental health programming uptake and implementation within public schools. TRIAL REGISTRATION: This trial is registered with clinicaltrials.gov (NCT05863520).

Patient-centered outcomes and outcome measurements for people aged 65 years and older-a scoping review.

INTRODUCTION: The aging population is a challenge for the healthcare system that must identify strategies that meet their needs. Practicing patient-centered care has been shown beneficial for this patient-group. The effect of patient-centered care is called patient-centered outcomes and can be appraised using outcomes measurements. OBJECTIVES: The main aim was to review and map existing knowledge related to patient-centered outcomes and patient-centered outcomes measurements for older people, as well as identify key-concepts and knowledge-gaps. The research questions were: How can patient-centered outcomes for older people be measured, and which patient-centered outcomes matters the most for the older people? STUDY DESIGN: Scoping review. METHODS: Search for relevant publications in electronical databases, grey literature databases and websites from year 2000 to 2021. Two reviewers independently screened titles and abstracts, followed by full text review and extraction of data using a data extraction framework. RESULTS: Eighteen studies were included, of which six with involvement of patients and/or experts in the process on determine the outcomes. Outcomes that matter the most to older people was interpreted as: access to- and experience of care, autonomy and control, cognition, daily living, emotional health, falls, general health, medications, overall survival, pain, participation in decision making, physical function, physical health, place of death, social role function, symptom burden, and time spent in hospital. The most frequently mentioned/used outcomes measurements tools were the Adult Social Care Outcomes Toolkit (ASCOT), EQ-5D, Gait Speed, Katz- ADL index, Patient Health Questionnaire (PHQ9), SF/RAND-36 and 4-Item Screening Zarit Burden Interview. CONCLUSIONS: Few studies have investigated the older people's opinion of what matters the most to them, which forms a knowledge-gap in the field. Future research should focus on providing older people a stronger voice in what they think matters the most to them.

My anesthesia Choice-HF: development and preliminary testing of a tool to facilitate conversations about anesthesia for hip fracture surgery.

BACKGROUND: Patients often desire involvement in anesthesia decisions, yet clinicians rarely explain anesthesia options or elicit preferences. We developed My Anesthesia Choice-Hip Fracture, a conversation aid about anesthesia options for hip fracture surgery and tested its preliminary efficacy and acceptability. METHODS: We developed a 1-page, tabular format, plain-language conversation aid with feedback from anesthesiologists, decision scientists, and community advisors. We conducted an online survey of English-speaking adults aged 50 and older. Participants imagined choosing between spinal and general anesthesia for hip fracture surgery. Before and after viewing the aid, participants answered a series of questions regarding key outcomes, including decisional conflict, knowledge about anesthesia options, and acceptability of the aid. RESULTS: Of 364/409 valid respondents, mean age was 64 (SD 8.9) and 59% were female. The proportion indicating decisional conflict decreased after reviewing the aid (63-34%, P < 0.001). Median knowledge scores increased from 50% correct to 67% correct (P < 0.001). 83% agreed that the aid would help them discuss options and preferences. 76.4% would approve of doctors using it. CONCLUSION: My Anesthesia Choice-Hip Fracture decreased decisional conflict and increased knowledge about anesthesia choices for hip fracture surgery. Respondents assessed it as acceptable for use in clinical settings. PRACTICE IMPLICATIONS: Use of clinical decision aids may increase shared decision-making; further testing is warranted.

Mission Alliance Community Engagement Project: Exploring the Impact of COVID-19 on Social Isolation, Loneliness, Mental Health and Wellbeing in Veterans.

During the Coronavirus disease pandemic, many U.S. veterans with posttraumatic stress disorder (PTSD) experienced increased symptomology and worsened mental health and well-being due in part to social isolation and loneliness. The Mission Alliance project explored these ramifications and prioritized critical issues expressed by U.S. veterans and stakeholders (N = 182) during virtual regional meetings (N = 32). Field notes created specifically for this project were recorded and thematically analyzed. Emerging themes included: (1) social isolation: missed opportunities, collapsed social circles, work-life balance, fostering relationships, and evolving health care delivery; (2) loneliness: deteriorated mental health, suffered with PTSD together but alone, looked out for each other, ambivalence toward technology, and strained and broken systems; (3) mental health: sense of chaos, increased demand and decreased access, aggravation, implementation of tools, innovative solutions, fear and loss, and availability of resources; (4) wellbeing: sense of purpose, holistic perspective on well-being, recognition of balance, persisting stigma, redefined pressures, freedom to direct treatment, and reconnection and disconnection. A PTSD-related patient centered outcomes research (PCOR)/comparative effectiveness research (CER) agenda was developed from these themes. Establishment of a veteran and stakeholder network is suggested to support, facilitate, and promote the PTSD-related PCOR/CER agenda. Furthermore, enhancement of opportunities for veterans with PTSD and stakeholders to partner in PCOR/CER is required to develop and conduct projects that lead to PTSD-related comprehensive care of veterans affected by traumatic events with the potential to translate findings to other populations.

Patient-centered outcomes in the POLO study of active maintenance olaparib for germline BRCA-mutated metastatic pancreatic cancer.

BACKGROUND: The phase 3 POLO study demonstrated a significant progression-free survival (PFS) benefit and preserved health-related quality of life (HRQOL) for active maintenance treatment with olaparib vs placebo in patients with metastatic pancreatic cancer and a germline BRCA mutation. Here, we present a post hoc analysis of the patient-centered outcomes: time without significant symptoms of disease progression or toxicity (TWiST) and quality-adjusted TWiST (Q-TWiST). METHODS: Patients were randomized 3:2 to maintenance olaparib (300 mg tablets twice daily) or placebo. Overall survival time was divided into TWiST, toxicity (TOX; time before disease progression with significant symptoms of toxicity), and relapse (REL; time after disease progression until death or censoring). Q-TWiST was the sum of TWiST, TOX, and REL, each weighted by HRQOL utility scores during the relevant health-state period. A base-case and three sensitivity analyses were performed using differing definitions of TOX. RESULTS: In total, 154 patients were randomized (olaparib, n = 92; placebo, n = 62). TWiST was significantly longer for olaparib than placebo in the base-case analysis (14.6 vs 7.1 months; 95% CI, 2.9-12.0; p = .001) and all sensitivity analyses. No statistically significant benefit for Q-TWiST was observed in the base-case analysis (18.4 vs 15.9 months; 95% CI, -1.1 to 6.1; p = .171) or the sensitivity analyses. CONCLUSION: These results support the previous findings that maintenance olaparib significantly improves PFS relative to placebo without compromising HRQOL and demonstrate that the clinically meaningful benefits of olaparib persist even when symptoms of toxicity are considered.

Development of a core outcome set for quality of life for adults with drug-resistant epilepsy: A multistakeholder Delphi consensus study.

OBJECTIVE: In 2017, the American Academy of Neurology (AAN) convened the AAN Quality Measurement Set working group to define the improvement and maintenance of quality of life (QOL) as a key outcome measure in epilepsy clinical practice. A core outcome set (COS), defined as an accepted, standardized set of outcomes that should be minimally measured and reported in an area of health care research and practice, has not previously been defined for QOL in adult epilepsy. METHODS: A cross-sectional Delphi consensus study was employed to attain consensus from patients and caregivers on the QOL outcomes that should be minimally measured and reported in epilepsy clinical practice. Candidate items were compiled from QOL scales recommended by the AAN 2017 Quality Measurement Set. Inclusion criteria to participate in the Delphi study were adults with drug-resistant epilepsy diagnosed by a physician, no prior diagnosis of psychogenic nonepileptic seizures or a cognitive and/or developmental disability, or caregivers of patients meeting these criteria. RESULTS: A total of 109 people satisfied inclusion/exclusion criteria and took part in Delphi Round 1 (patients, n = 95, 87.2%; caregivers, n = 14, 12.8%), and 55 people from Round 1 completed Round 2 (patients, n = 43, 78.2%; caregivers, n = 12, 21.8%). One hundred three people took part in the final consensus round. Consensus was attained by patients/caregivers on a set of 36 outcomes that should minimally be included in the QOL COS. Of these, 32 of the 36 outcomes (88.8%) pertained to areas outside of seizure frequency and severity. SIGNIFICANCE: Using patient-centered Delphi methodology, this study defines the first COS for QOL measurement in clinical practice for adults with drug-resistant epilepsy. This set highlights the diversity of factors beyond seizure frequency and severity that impact QOL in epilepsy.

Timing of sedation and patient-reported pain outcomes during cardiac catheterization: Results from the UNTAP-intervention study.

BACKGROUND: Invasive cardiac catheterization (CC) temporarily increases pain, discomfort, and anxiety. Procedural sedation is deployed to mitigate these symptoms, though practice varies. Research evaluating peri-procedural patient-reported outcomes is lacking. METHODS AND RESULTS: We randomized 175 patients undergoing CC to short interval ([SI] group, <6 min) or long interval ([LI] group, ≥6 min) time intervals between initial intravenous sedation and local anesthetic administration. Outcomes included: (1) total pain medication use, (2) patient-reported and behaviorally assessed pain and (3) patient satisfaction during outpatient CC. Generalized linear mixed effect models were used to evaluate the impact of treatment time interval on total medication utilization, pain, and satisfaction. Among enrollees the mean age was 62 (standard deviation [SD] = 13.4), a majority were male (66%), white (74%), and overweight (mean body mass index = 28.5 [SD = 5.6]). Total pain medication use did not vary between treatment groups (p = 0.257), with no difference in total fentanyl (p = 0.288) or midazolam (p = 0.292). Post-treatment pain levels and nurse-observed pain were not statistically significant between groups (p = 0.324 & p = 0.656, respectively. No significant differences with satisfaction with sedation were found between the groups (p = 0.95) Patient-reported pain, satisfaction and nurse-observed measures of pain did not differ, after adjustment for demographic and procedural factors. Analyses of treatment effect modification revealed that postprocedure self-reported pain levels varied systematically between individuals undergoing percutaneous coronary intervention (PCI) (SI = 2.2 [0.8, 3.6] vs. LI = 0.7 [-0.6, 2.0]) compared with participants not undergoing PCI (SI = 0.4 [-0.8, 1.7] vs. LI = 0.7 [-0.3, 1.6]) (p = 0.043 for interaction). CONCLUSION: No consistent treatment differences were found for total medication dose, pain, or satisfaction regardless of timing between sedation and local anesthetic. Treatment moderations were seen for patients undergoing PCI. Further investigation of how procedural and individual factors impact the patient experience during CC is needed.

Incorporating economic analysis in interventional cardiology research.

Evaluative research in interventional cardiology has focused on clinical and technical outcomes. Inclusion of economic data can enhance evaluative research by quantifying the relative economic burden incurred by different therapies. When combined with clinical outcomes, cost data can provide a measure of value (e.g., marginal cost-effectiveness). In some select situations, cost data can also be used as surrogates for complexity of care and morbidity. In this narrative review, we aim to provide a framework for the application of cost data in clinical trials and observational research, detailing how to incorporate this kind of data into interventional cardiology research.

Maternal Anxiety and Empowerment in Pregnancies Complicated By Fetal Surgical Anomalies: A Mixed Methods Study.

INTRODUCTION: Fetal surgical anomalies cause significant anxiety. Following the diagnosis, prenatal counseling with shared decision-making occurs. Empowerment is an essential component of shared decision-making. The purpose of this mixed-methods study was to evaluate the association between patient empowerment with depression and anxiety among patients with fetal surgical anomalies. METHODS: An explanatory mixed-methods study was conducted at a large tertiary fetal center among patients with recently diagnosed surgical fetal anomalies from May, 2021 to May, 2022. Validated cross-sectional surveys were used to collect quantitative data regarding patient empowerment, depression, and anxiety. Univariate analysis was used to compare the association of maternal empowerment with depression and anxiety. Qualitative data was obtained from semistructured interviews to explore maternal anxiety and depression relative to the fetal diagnosis. Thematic analysis was performed to identify themes. RESULTS: Seventy-four patients were recruited for the quantitative study. Pregnancy-related empowerment score and patient empowerment score were significantly lower for expectant mothers with high anxiety (P < 0.01). Eighteen patients participated in qualitative interviews. Participants expressed significant anxiety related to their fetal diagnosis. Exacerbating stressors included social determinants, personal history of miscarriage, and changing family dynamics. CONCLUSION: Our results suggest there is an association between increased depression and anxiety with lower empowerment. These findings have important implications for prenatal counseling, as targeted interventions to improve psychosocial support to treat depression and anxiety might also improve empowerment.

Enhancing Patient Centricity of Real-World Data Research: An Exploratory Analysis Using the Patient Experience Mapping Toolbox.

OBJECTIVES: There is an increasing expectation that medical product development and assessment be guided by patient input captured through patient engagement. Recently published consensus guidelines describe how qualitative patient experience data (PED) can guide the design, conduct, and translation of real-world research that reflects patients' lived experience. The objective of this exploratory analysis is to examine how researchers could leverage PED captured through the Patient Experience Mapping Toolbox (PEMT) to guide real-world data (RWD) research designs. METHODS: This exploratory analysis included a thematic analysis of interview transcripts collected while pilot testing the PEMT followed by a qualitative analysis of the emerging themes aligned with stages listed in the patient-centered real-world evidence, Real-World Research Design Framework. RESULTS: PED collected using the PEMT include information about symptomology, interactions with the healthcare system, information-seeking behavior, misdiagnoses, lifestyle changes, treatments, side effects, and comorbidities. This information can be leveraged at key study design decisions, including (1) identifying study cohorts and subgroups, (2) identifying exposures, (3) informing covariates and potential confounders; and (4) refining study periods. Additionally, participants described where they seek information about treatments and diseases, which should inform dissemination strategies. CONCLUSIONS: We identified opportunities for PED collected using the PEMT to inform RWD study designs. The PED described in this exploratory analysis stem from pilot testing of the PEMT across a variety of conditions. In the next phase of development in this area, researchers should evaluate how data collected using the PEMT can be applied to RWD research for a specific disease.

Reduced versus standard intradetrusor OnabotulinumtoxinA injections for treatment of overactive bladder.

BACKGROUND: Intradetrusor onabotulinumtoxinA injection is an effective advanced treatment for overactive bladder. While the effective dosages have been well studied, very little data exist on treatment efficacy using differing injection techniques. The objective of this study was to determine whether the efficacy of a reduced injection technique of 5 injection sites was noninferior to the standard technique of 20 injection sites of intradetrusor onabotulinumtoxinA for treatment of overactive bladder. METHODS: In this randomized noninferiority trial, men and women seeking treatment of overactive bladder with intradetrusor onabotulinumtoxinA injections were randomized to receive 100 units administered via either a reduced injection technique of 5 injection sites or a standard injection technique of 20 injection sites. Subjects completed a series of standardized questionnaires at baseline and at 4-12 weeks postprocedure to determine symptom severity and treatment efficacy. The primary outcome was treatment efficacy as determined by Overactive Bladder Questionnaire-Short Form with a noninferiority margin of 15 points. Secondary outcomes were incidence of urinary tract infection and urinary retention requiring catheterization. RESULTS: Data from 77 subjects were available for analysis with 39 in the control arm (20 injections) and 38 in the study arm (5 injections). There was a significant improvement in both arms from baseline to follow-up in Overactive Bladder Questionnaire-Short Form and International Consultation on Incontinence Questionnaire scores (p < 0.001). Overall treatment success was 68% with no statistically significant difference between arms. A significant difference between arms was found on the Overactive Bladder Questionnaire-Short Form quality of life survey favoring the control arm (confidence interval [CI]: 0.36-20.5, p = 0.04). However, there were no significant differences between arms in the remaining validated questionnaires. The study arm did not demonstrate noninferiority to the control arm. Subjects in the study arm were significantly more likely to express a willingness to undergo the procedure again (odds ratio = 3.8, 95% CI: 1.42-10.67, p = 0.004). Adverse events did not differ between arms. CONCLUSIONS: A reduced injection technique for administration of intradetrusor onabotulinumtoxinA demonstrates similar efficacy to the standard injection technique but did not demonstrate noninferiority. Subjects preferred the reduced injection technique over the standard technique. A reduced injection technique is a safe and effective alternative to the standard technique.

The learning health system for pediatric nephrology: building better systems to improve health.

Learning health systems (LHS) align science, informatics, incentives, and culture for continuous improvement and innovation. In this organizational system, best practices are seamlessly embedded in the delivery process, and new knowledge is captured as an integral byproduct of the care delivery experience aimed to transform clinical practice and improve patient outcomes. The objective of this review is to describe how building better health systems that integrate clinical care, improvement, and research as part of an LHS can improve care within pediatric nephrology. This review will provide real-world examples of how this system can be established in a single center and across multiple centers as learning health networks.

Telemedicine-based inspiratory muscle training and walking promotion with lung cancer survivors following curative intent therapy: a parallel-group pilot randomized trial.

PURPOSE: Following curative-intent therapy of lung cancer, many survivors experience dyspnea and physical inactivity. We investigated the feasibility, acceptability, safety, and potential efficacy of inspiratory muscle training (IMT) and walking promotion to disrupt a postulated "dyspnea-inactivity" spiral. METHODS: Between January and December 2022, we recruited lung cancer survivors from Kaiser Permanente Colorado who completed curative-intent therapy within 1-6 months into a phase-IIb, parallel-group, pilot randomized trial (1:1 allocation). The 12-week intervention, delivered via telemedicine, consisted of exercise training (IMT + walking), education, and behavior change support. Control participants received educational materials on general exercise. We determined feasibility a priori: enrollment of ≥ 20% eligible patients, ≥ 75% retention, study measure completion, and adherence. We assessed acceptability using the Telemedicine-Satisfaction-and-Usefulness-Questionnaire and safety events that included emergency department visits or hospitalizations. Patient-centered outcome measures (PCOMs) included dyspnea (University-of-California-San-Diego-Shortness-of-Breath-Questionnaire), physical activity (activPAL™ steps/day), functional exercise capacity (mobile-based-six-minute-walk-test), and health-related quality of life (HRQL, St.-George's-Respiratory-Questionnaire). We used linear mixed-effects models to assess potential efficacy. RESULTS: We screened 751 patients, identified 124 eligible, and consented 31 (25%) participants. Among 28 participants randomized (14/group), 22 (11/group) completed the study (79% retention). Intervention participants returned > 90% of self-reported activity logs, completed > 90% of PCOMs, and attended > 90% of tele-visits; 75% of participants performed IMT at the recommended dose. Participants had high satisfaction with tele-visits and found the intervention useful. There was no statistically significant difference in safety events between groups. Compared to control participants from baseline to follow-up, intervention participants had statistically significant and clinically meaningful improved HRQL (SGRQ total, symptom, and impact scores) (standardized effect size: -1.03 to -1.30). CONCLUSIONS: Among lung cancer survivors following curative-intent therapy, telemedicine-based IMT + walking was feasible, acceptable, safe, and had potential to disrupt the "dyspnea-inactivity" spiral. Future efficacy/effectiveness trials are warranted and should incorporate IMT and walking promotion to improve HRQL. TRIAL REGISTRATION: ClinicalTrials.gov NCT05059132.

Characteristics associated with subjective and objective measures of treatment success in women undergoing percutaneous tibial nerve stimulation vs sham for accidental bowel leakage.

INTRODUCTION AND HYPOTHESIS: In randomized trials both percutaneous tibial nerve stimulation (PTNS) and sham result in clinically significant improvements in accidental bowel leakage (ABL). We aimed to identify subgroups who may preferentially benefit from PTNS in women enrolled in a multicenter randomized trial. METHODS: This planned secondary analysis explored factors associated with success for PTNS vs sham using various definitions: treatment responder using three cutoff points for St. Mark's score (≥3-, ≥4-, and ≥5-point reduction); Patient Global Impression of Improvement (PGI-I) of ≥ much better; and ≥50% reduction in fecal incontinence episodes (FIEs). Backward logistic regression models were generated using elements with significance of p<0.2 for each definition and interaction terms assessed differential effects of PTNS vs sham. RESULTS: Of 166 women randomized, 160 provided data for at least one success definition. Overall, success rates were 65% (102 out of 158), 57% (90 out of 158), and 46% (73 out of 158) for ≥3-, ≥4-, and ≥5-point St Mark's reduction respectively; 43% (68 out of 157) for PGI-I; and 48% (70 out of 145) for ≥50% FIEs. Of those providing data for all definitions of success, 77% (109 out of 142) met one success criterion, 43% (61 out of 142) two, and 29% (41 out of 142) all three success criteria. No reliable or consistent factors were associated with improved outcomes with PTNS over sham regardless of definition. CONCLUSIONS: Despite exploring diverse success outcomes, no subgroups of women with ABL differentially responded to PTNS over sham. Success results varied widely across subjective and objective definitions. Further investigation of ABL treatment success definitions that consistently and accurately capture patient symptom burden and improvement are needed.

Group 2 ITI Consensus Report: Technological developments in implant prosthetics.

OBJECTIVES: Group-2 reviewed the scientific evidence in the field of «Technology¼. Focused research questions were: (1) additive versus subtractive manufacturing of implant restorations; (2) survival, complications, and esthetics comparing prefabricated versus customized abutments; and (3) survival of posterior implant-supported multi-unit fixed dental prostheses. MATERIALS AND METHODS: Literature was systematically screened, and 67 publications could be critically reviewed following PRISMA guidelines, resulting in three systematic reviews. Consensus statements were presented to the plenary where after modification, those were accepted. RESULTS: Additively fabricated implant restorations of zirconia and polymers were investigated for marginal/internal adaptation and mechanical properties without clear results in favor of one technology or material. Titanium base abutments for screw-retained implant single crowns compared to customized abutments did not show significant differences concerning 1-year survival. PFM, veneered and monolithic zirconia implant-supported multi-unit posterior fixed dental prostheses demonstrated similar high 3-year survival rates, whereas veneered restorations exhibited the highest annual ceramic fracture and chipping rates. CONCLUSIONS: For interim tooth-colored implant single crowns both additive and subtractive manufacturing are viable techniques. The clinical performance of additively produced restorations remains to be investigated. Implant single crowns on titanium base abutments show similar clinical performance compared to other type of abutments; however, long-term clinical data from RCTs are needed. The abutment selection should be considered already during the planning phase. Digital planning facilitates 3D visualization of the prosthetic design including abutment selection. In the posterior area, monolithic zirconia is recommended as the material of choice for multi-unit implant restorations to reduce technical complications.
