Assessing Surgeon Familiarity with the Commission on Cancer Operative Standards for Cancer Surgery.

BACKGROUND: In response to growing evidence that proper performance of operative techniques during cancer surgery is associated with improved patient outcomes, the American College of Surgeons (ACS) implemented six operative standards as part of Commission on Cancer (CoC) accreditation. This study aimed to assess surgeon familiarity with these standards when first introduced and 2 years after their adoption. METHODS: The ACS Cancer Surgery Standards Program distributed an anonymous 36-question survey to CoC-accredited cancer programs in 2021 and 2023. Questions specific to operative techniques determined the Surgery Score, and those specific to the accreditation standards determined the Standards Score. Mean scores were compared using one-way analysis of variance (ANOVA) and t tests. RESULTS: The survey was completed by 376 surgeons in 2021 and 380 surgeons in 2023. The Surgery Scores were higher than the Standards Scores in 2021 and 2023. The surgeons who practiced at institutions with CoC accreditation had significantly higher Standards Scores than the surgeons at non-accredited institutions in 2021 (p = 0.005) and 2023 (p = 0.004), but not significantly different Surgery Scores. CONCLUSIONS: The baseline survey in 2021 demonstrated significant knowledge of technical aspects of cancer surgery among a broad surgeon base, but a need for greater understanding of the accreditation standards. The repeat survey distribution 2 years after rollout of the operative standards and associated educational programing showed increased awareness surrounding the operative standards in 2023 and a trend toward improvement in knowledge of the accreditation standards across all specialties. Further evaluation will be directed toward compliance with the accreditation standards.

Defining Breast Cryoablation Treatment Success: A Guide for the Curative and Palliative Treatment of Breast Cancer.

RATIONALE AND OBJECTIVES: Recent ICE3 trial of breast cryoablation for breast cancer demonstrated 98% success rate, similar to breast-conserving surgery. However, ICE3 and other published studies did not differentiate curative from palliative treatment nor define patient-specific treatment objectives. We sought to define treatment success of curative and palliative breast cryoablation for breast cancer in meeting procedure objectives and patient-specific treatment objectives. MATERIALS AND METHODS: We conducted a retrospective analysis of breast cancer patients who underwent breast cryoablation during 2021-2024. Breast radiologists performed outpatient cryoablation using local anesthesia and argon gas cryoprobes under ultrasound or MRI guidance. Patient demographics, referral indications, tumor characteristics, procedure details, and imaging follow-up findings were analyzed. Cryoablation was categorized as curative or palliative. Treatment success was defined as achievement of both procedure and patient-specific treatment objectives. RESULTS: Breast cryoablation was performed for 34 lesions in 29 patients with N0M0 (n = 25), N1M0 (n = 2), N2M0 (n = 1), and N0M1 (n = 1) disease. Most tumors were invasive ductal carcinoma (IDC), low to intermediate grade, estrogen receptor (ER) and progesterone receptor (PR) positive and HER2 negative (23 tumors, 68%). Tumor size ranged from 0.4-1.9 (median 0.8) cm for curative cryoablation and 0.6-6.0 (median 1.3) cm for palliative cryoablation. For 27 patients with follow-up imaging, ablation was curative in 14 patients, 14 tumors and palliative in 13 patients, 18 lesions. Imaging follow-up time ranged from 3 to 26 (median 16) months, > 12 months in 22 of 27 patients and 25 of 32 tumors. Complications were limited to 2 cases of skin frost injury, 1 mild and 1 moderate. Treatment success was achieved in 13 of 14 patients with curative and all 13 patients with palliative cryoablation. CONCLUSION: Our study defines treatment success for curative and palliative breast cryoablation, demonstrates breast cryoablation achieves not only procedure (technical) but also patient-specific treatment objectives without significant complications, and may serve as guide for integrating breast cryoablation in the treatment of breast cancer patients.

Tinnitus reduction in patients with single-sided deafness: the effect of cochlear implantation, bone conduction devices, and contralateral routing of sound hearing aids investigated in a randomized controlled trial.

Objectives: Single-sided deafness (SSD) is often accompanied by tinnitus, resulting in a decreased quality of life. Currently, there is a lack of high level of evidence studies comparing different treatment options for SSD regarding tinnitus reduction. This randomized controlled trial (RCT) evaluated the effect of a cochlear implant (CI), bone conduction device (BCD), contralateral routing of sound (CROS), and no treatment on tinnitus outcomes in SSD patients, with follow-up extending to 24 months. Methods: A total of 120 adult SSD patients were randomized to three groups: CI, a trial period with first a BCD on a headband, then a CROS, or vice versa. After the trial periods, patients opted for a BCD, CROS, or no treatment. At the start of follow-up, 28 patients were implanted with a CI, 25 patients with a BCD, 34 patients had a CROS, and 26 patients chose no treatment. The Tinnitus Handicap Inventory (THI), Tinnitus Questionnaire (TQ), the Visual Analog Scale (VAS), and the Hospital Anxiety and Depression Scale (HADS) were completed at baseline and at 3, 6, 12, and 24 months of follow-up. Results: The CI and BCD groups showed significantly decreased tinnitus impact scores. The CI group showed the largest decrease, which was already observed at 3 months of follow-up. Compared to the baseline, the median THI score decreased by 23 points, the TQ score by 17 points, and the VAS score by 60 points at 24 months. In the BCD group, the TQ score decreased by 9 points, and the VAS decreased by 25 points at 24 months. The HADS anxiety and depression subscale showed no indication for anxiety or depression at baseline, nor at 24 months, for all groups. Conclusion: In this RCT, SSD patients treated with a CI or BCD showed an overall decrease in tinnitus impact scores up to 24 months compared to baseline. The CI group reported a stable and the largest reduction. Cochlear implants appear to be superior to BCD and CROS, and no treatment for achieving partial or complete resolution of tinnitus in patients with SSD.

Beyond surgery: the proper role and delivery of radiation therapy in the local-regional management of BIA-ALCL.

For localized breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), surgical resection is crucial; however, radiation therapy (RT) can be utilized as local-regional therapy if surgery is incomplete or not recommended. We present the case of a woman with BIA-ALCL who received systemic therapy and consolidation RT.

Landscape analysis of the Kenyan policy on the treatment and prevention of diarrheal disease among under-5 children.

OBJECTIVE: Diarrhoea remains a leading cause of morbidity and death among under-5 children in Kenya, despite multipronged policy and programme initiatives to increase access to treatment. This study interrogates the comprehensiveness and adequacy of Kenya's policies, frameworks and action plans for diarrheal management and prevention. The study seeks to identify policy and practice gaps that need to be filled to strengthen diarrhoea treatment and prevention among under-5 children in Kenya. DESIGN: Our study is a landscape analysis, which seeks to identify the gaps in the current Kenya diarrheal policy, frameworks and action plans. The critical questions included their comprehensiveness, the availability of elaborate treatment, management and prevention solutions, together with updatedness, building on evidence from extant literature on key pathways to infection relating to man-animal environmental interaction, which are critical in enteric infection prevention initiatives. DATA SOURCES: We conducted an internet search of databases of Government of Kenya's Ministry of Health; relevant websites/publications of international organisations and groups (Centre for Disease Control and Prevention, UNICEF and WHO) and published and grey literature (Google searches, Google Scholar and PubMed). ELIGIBILITY CRITERIA: Included are publicly available key national diarrheal policy frameworks, plans, strategies, laws, institutional frameworks and operational guidelines that inform pertinent questions on the adequacy of policy and practice and preventive policy updates and actions. Further, peer-reviewed and grey literature on diarrheal morbidity and mortality and diarrheal prevention and management are included. The analysis excluded any information that was not referenced on the internet nor obtained from the internet. DATA EXTRACTION AND SYNTHESIS: The review team extracted the key provisions of the policy guidelines guided by a checklist and questions around the adequacy of existing national policies in addressing the determinants, prevention and treatment interventions of enteric infections and diarrhoea among under-5 children in the country. The checklist covered Kenyan background and diarrhoea situation analysis, policy objectives, policy strategies and policy implementation. RESULTS: The analysis identified a corpus of strategies for the management of diarrhoea at multiple levels: health facilities, communities and households. The policies highlighted advocacy, health communication and social mobilisation, as well as logistics management and prevention strategies. However, the triangulation of evidence from the policy provisions and extant literature identified critical policy gaps in diarrhoea prevention and management in Kenya, particularly the lack of focus on zoonotic pathways to enteric infection, environment-pathogen linkages and operationalisation of the roles of social determinants of health and related services. The policy documents had limited focus on rapid diagnosis, vaccine development and deployment, together with weak funding commitment towards implementation and unclear pathways to funding responsibilities. CONCLUSION: Policies are central to guiding programmatic actions towards effective enteric and diarrhoea prevention and management measures in Kenya. This study shows the need for policy updates to reflect pathways to enteric infections not covered in the current policy guidelines. Further, there is a need to strengthen the treatment and management of infection through rapid diagnosis, vaccine development and deployment, and strong funding commitment towards implementation together with clear funding responsibilities. Together, these will be vital in strengthening the current policy provisions and addressing other pathways to the prevention of enteric infections relating to zoonotic, environment-pathogen linkages and social determinants of health in Kenya and other low-income and middle-income countries.

Improved Pulmonary Artery Evaluation Using High-Pitch Photon-Counting CT Compared to High-Pitch Conventional or Routine-Pitch Conventional Dual-Energy CT.

OBJECTIVE: Pulmonary CT angiography (CTA) to detect pulmonary emboli can be performed using conventional dual-source CT with single-energy acquisition at high-pitch (high-pitch conventional CT), which minimizes motion artifacts, or routine-pitch, dual-energy acquisitions (routine-pitch conventional DECT), which maximize iodine signal. We compared iodine signal, radiation dose, and motion artifacts of pulmonary CTA between these conventional CT modalities and dual-source photon-counting detector CT with high-pitch, multienergy acquisitions (high-pitch photon-counting CT). METHODS: Consecutive clinically indicated pulmonary CTA exams were collected. CT number/noise was measured from the main to right lower lobe segmental pulmonary arteries using 120 kV threshold low, 120 kV, and mixed kV (0.6 linear blend) images. Three radiologists reviewed anonymized, randomized exams, rating them using a 4- or 5-point Likert scale (1 = worst, and 4/5 = best) for contrast enhancement in pulmonary arteries, motion artifacts in aortic root to subsegmental pulmonary arteries, lung image quality; pulmonary blood volume (PBV) map image quality (for multienergy or dual-energy exams), and contribution to reader confidence. RESULTS: One hundred fifty patients underwent high-pitch photon-counting CT (n = 50), high-pitch conventional CT (n = 50), and routine-pitch conventional DECT (n = 50). High-pitch photon-counting CT had lower radiation dose (CTDIvol: 8.1 ± 2.5 vs 9.6 ± 6.8 and 16.2 ± 8.5 mGy, respectively; P < 0.001), and routine-pitch conventional DECT had significantly less contrast (P < 0.009). CT number and CNR measurements were significantly greater at high-pitch photon-counting CT (P < 0.001). Across readers, high-pitch photon-counting CT demonstrated significantly higher subjective contrast enhancement in the pulmonary arteries compared to the other modalities (4.7 ± 0.6 vs 4.4 ± 0.7 vs 4.3 ± 0.7; P = 0.011) and lung image quality (3.4 ± 0.5 vs 3.1 ± 0.5 vs 3.1 ± 0.5; P = 0.013). High-pitch photon-counting CT and high-pitch conventional CT had fewer motion artifacts at all levels compared to DECT (P < 0.001). High-pitch photon-counting CT PBV maps had superior image quality (P < 0.001) and contribution to reader confidence (P < 0.001) compared to routine-pitch conventional DECT. CONCLUSION: High-pitch photon-counting pulmonary CTA demonstrated higher contrast in pulmonary arteries at lower radiation doses with improved lung image quality and fewer motion artifacts compared to high-pitch conventional CT and routine-pitch conventional dual-energy CT.

Clinical Variables Influencing Outcomes in Patients with Atypical Intradermal Smooth Muscle Neoplasms (Formerly Cutaneous Leiomyosarcomas): Single-Institution Study of 95 Surgical Patients.

BACKGROUND: Atypical intradermal smooth muscle neoplasm, also commonly termed cutaneous leiomyosarcoma, is a soft tissue tumor with a low risk of aggressive behavior. These lesions arise in the dermis with possible superficial subcutaneous extension, demonstrate cytologic atypia, and often show mitotic activity. METHODS: A retrospective review of patient demographics, tumor characteristics, and treatment methods was conducted in a consecutive series of patients presenting to MD Anderson Cancer Center (MDACC) from 2002 to 2021 (n = 95). All pathology was reviewed by MDACC pathologists and determined to be atypical intradermal smooth muscle neoplasm. RESULTS: Median age at diagnosis was 58 years (range 22-86), and 74% were male. Ninety-five percent (n = 90) of patients identified as White, non-Hispanic. Most tumors were slow-growing, solitary, and painless nodules. Tumors were in the lower extremities (44.2%), followed by the upper extremity (28.4%), trunk (22.1%), and head and neck (5.2%). All patients (n = 44, 46.3%) who had a punch/incisional biopsy for diagnostic purposes had a subsequent tumor excision. Unplanned excision or excisional biopsy was performed on the remaining 46 (48%) patients. Of this subset, 41 of the 46 aforementioned patients (89%) had positive margins and underwent re-excision. Final pathology in 25/38 (66%) re-excision specimens was negative for residual tumor despite an initial positive margin. Two patients in the cohort had local recurrence 2 and 3 years after initial surgery. Both patients had positive margins, underwent excision of the recurrent tumor, and remain free of disease. After median follow-up of 6.9 years (range 1 day-18 years), 5-year recurrence-free survival was 96% and overall survival (OS) of the entire cohort was 78%. CONCLUSION: In this study of consecutive patients presenting with atypical intradermal smooth muscle neoplasm, we found good OS and local control after definitive surgical excision with negative margins, including excisional biopsy with close margins. Atypical intradermal smooth muscle neoplasm is unlikely to metastasize and has an excellent prognosis. Guidelines to determine optimal surveillance strategies for these patients should be revisited.

Multiparametric MRI-based radiomic models for early prediction of response to neoadjuvant systemic therapy in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is often treated with neoadjuvant systemic therapy (NAST). We investigated if radiomic models based on multiparametric Magnetic Resonance Imaging (MRI) obtained early during NAST predict pathologic complete response (pCR). We included 163 patients with stage I-III TNBC with multiparametric MRI at baseline and after 2 (C2) and 4 cycles of NAST. Seventy-eight patients (48%) had pCR, and 85 (52%) had non-pCR. Thirty-six multivariate models combining radiomic features from dynamic contrast-enhanced MRI and diffusion-weighted imaging had an area under the receiver operating characteristics curve (AUC) > 0.7. The top-performing model combined 35 radiomic features of relative difference between C2 and baseline; had an AUC = 0.905 in the training and AUC = 0.802 in the testing set. There was high inter-reader agreement and very similar AUC values of the pCR prediction models for the 2 readers. Our data supports multiparametric MRI-based radiomic models for early prediction of NAST response in TNBC.

Prenatal exposure to non-persistent chemicals and fetal-to-childhood growth trajectories.

INTRODUCTION: Prenatal exposure to non-persistent chemicals, including organophosphate pesticides, phthalates, and bisphenols, is associated with altered fetal and childhood growth. Few studies have examined these associations using longitudinal growth trajectories or considering exposure to chemical mixtures. METHODS: Among 777 participants from the Generation R Study, we used growth mixture models to identify weight and body mass index (BMI) trajectories using weight and height measures collected from the prenatal period to age 13. We measured exposure biomarkers for organophosphate pesticides, phthalates, and bisphenols in maternal urine at three timepoints during pregnancy. Multinomial logistic regression was used to estimate associations between averaged exposure biomarker concentrations and growth trajectories. We used quantile g-computation to estimate joint associations with growth trajectories. RESULTS: Phthalic acid (OR: 1.4, 95% CI: 1.01, 1.9) and bisphenol A (BPA; OR: 1.5, 95% CI: 1.0, 2.2) were associated with higher odds of a growth trajectory characterized by smaller prenatal and larger childhood weight relative to a referent trajectory of larger prenatal and average childhood weight. Biomarkers of organophosphate pesticides, individually and jointly, were associated with lower odds of a growth trajectory characterized by average prenatal and lower childhood weight. CONCLUSIONS: Exposure to phthalates and BPA was positively associated with a weight trajectory characterized by lower prenatal and higher childhood weight, while exposure to organophosphate pesticides was negatively associated with a trajectory of average prenatal and lower childhood weight. This study is consistent with the hypothesis that non-persistent chemical exposures disrupt growth trajectories from the prenatal period through childhood.

Residual Nodal Burden After Neoadjuvant Chemotherapy in cN1 Breast Cancer Patients with Positive Nodes at Targeted Axillary Dissection.

BACKGROUND: Targeted axillary dissection (TAD) facilitates nodal staging in cN1 breast cancer after neoadjuvant chemotherapy (NAC). Completion axillary node dissection (cALND) remains the standard of care for TAD-positive patients. This study investigated factors associated with additional positive nodes at cALND (cALND+) and the impact on the residual cancer burden (RCB). METHODS: Retrospective review of cN1 breast cancer patients treated with NAC and TAD was conducted from July 2013 to June 2023. The review defined cN1 status by ultrasound (US) and biopsy. Patient, tumor, and treatment characteristics were evaluated. Multivariate analysis was performed to identify factors associated with cALND+, and RCB was calculated. RESULTS: Of 902 patients who underwent TAD, 554 (61.4%) were TAD-positive. 457 underwent cALND, and 124 (27%) were cALND+ (average 4.1 additional +nodes). The cALND+ patients had larger primary tumors at diagnosis (4 vs 3.5 cm; p = 0.04), more than three suspicious nodes on initial US (30% vs 13%; p ≤ 0.0001), larger residual primary tumors on pathology (median, 3 vs 2.1 cm; p = 0.0004), and more positive TAD nodes (median, 2 vs 1; p ≤ 0.0001). In the multivariate analysis, the factors associated with cALND+ were more than three suspicious nodes on initial US (odds ratio [OR], 2.9; p ≤ 0.0001), more positive TAD nodes (OR, 1.1; p ≤ 0.0001), larger clipped node metastasis (OR, 1.1; p ≤ 0.0001), and larger residual tumor on pathology (OR, 1.1; p = 0.006). Of 65 cALND+ patients with RCB class I or II, 29 (45%) had an increase in RCB based on cALND. CONCLUSION: Of cN1 breast cancer patients treated with NAC who are TAD-positive, approximately 25% will have additional nodal disease on cALND. In these patients, positive cALND is associated with greater disease burden, which has potential implications for RCB status and prognosis.

Variations in Retinal Oxygen Saturation in a Diverse Healthy Population.

Purpose: Local retinal oxygen saturation is a research technique, which has the potential as a biomarker for diabetes. However, normative data has not been established. This study examined differences in oxygen saturation around the macula and characterizes the relationship between age, race, refractive error (RE), sex, blood pressure (BP), prediabetic status and oxygen saturation. Methods: Fifty-nine subjects aged 22-69 (38.8 ± 14.7 years) were included who were racially diverse and with equal gender distribution. None had eye disease. Oxygen saturation was taken with the Zilia Ocular in 4 locations around the macula 3.1 degrees from the fovea and they were also averaged. BP, RE, and HbA1c were noted. Regression analyses for oximetry and other factors were completed as were t-tests with multiple comparison corrections. Results: There were significant variations in oximetry measures by race, with higher pigmentation levels associated with lower oximetry values (p < 0.01). There was no relationship between oximetry and sex (p = 0.34), RE (p = 0.67), BP (systolic p = 0.61, diastolic p = 0.71) nor prediabetic status (p = 0.87). Oximetry was associated with age when controlling for race (P < 0.002). Nasal-temporal variations showed nasal oximetry to higher than temporal measures (P < 0.01). Conclusion: This study revealed race/pigmentation is an important influence on oximetry measures. Retinal location also caused variations, likely due to proximity to larger vessels nasally. No differences in sex, RE nor BP were observed to alter local oxygen saturation. However, age was correlated when considered with race. This study will inform our future work in different disease states and is an important first step in evaluating this technology.

This study evaluates a new research instrument (Zilia Ocular) which measures how much oxygen is in the very small blood vessels of the retina. Our group wanted to evaluate healthy people to find out if the measurements the instrument takes are different in different sexes, ages, races, glasses prescriptions and blood pressures. We also looked at if they were changed in people with prediabetes and if it is different in different locations on the retina. We found that the measures are different in different races and ages. The measures also change with location in the eye. The other factors did not change the measurements of oxygen saturation on this instrument. We need to know this information because we want to detect changes in the retina in diabetes in diverse patient groups; however, we need to know about normal variations to better understand and collect that data.

The Prevalence of Sentinel Lymph Node Positivity and Implications for the Utility of Frozen Section Diagnosis Following Neoadjuvant Systemic Therapy in Patients with Clinically Node-Negative HER2-Positive or Triple-Negative Breast Cancer.

BACKGROUND: Axillary dissection is the standard of care for patients with positive sentinel lymph nodes (SLNs) following neoadjuvant systemic therapy. Frozen section can provide intraoperative information regarding the need for axillary dissection during the index operation. However, there are limited data on the utility of frozen section in patients with clinically node-negative (cN0) HER2-positive or triple-negative breast cancer. METHODS: We conducted a single-institution observational cohort study including patients with non-inflammatory, cN0, HER2-positive or triple-negative breast cancer treated with neoadjuvant systemic therapy between 2015 and 2019. We estimated the prevalence of SLN positivity and the diagnostic test characteristics of SLN frozen section. RESULTS: Overall, 662 patients were eligible for inclusion, and 44 patients had one or more positive SLNs (prevalence: 6.6%, 95% confidence interval [CI] 4.9-8.8). There were 490 (74.0%) patients who had intraoperative frozen section, and 19 (3.9%) tested positive among 33 (6.7%) with positive final pathology. Frozen section sensitivity was 57.6% (95% CI 39.2-74.5), specificity was 100% (95% CI 99.2-100), positive predictive value was 100% (95% CI 82.4-100), and negative predictive value was 97.0% (95% CI 95.1-98.4). The sensitivity of frozen section for detection of micrometastases or isolated tumor cells was 35.3% (95% CI 14.2-61.7). CONCLUSION: In patients with cN0 HER2-positive or triple-negative breast cancer who have been treated with neoadjuvant therapy, positive SLNs are uncommon and frozen section sensitivity is modest. Decisions to defer SLN evaluation to final pathology, which may be reasonable in many settings, can be informed, in part, by these findings.

A framework of research priorities in COVID rehabilitation from the Rehabilitation Science Research Network for COVID: an international consultation involving qualitative and quantitative research.

PURPOSE: To identify research priorities related to COVID rehabilitation from the perspectives of persons with lived experiences, clinicians, researchers, community organization and policy representatives. MATERIALS & METHODS: We conducted five international consultations to identify key issues and research priorities in COVID rehabilitation using (i) web-based questionnaires, (ii) synchronous discussions, and (iii) content analysis of COVID rehabilitation research conference presentations. We collated responses and notes and then analyzed data using content analytical techniques. RESULTS: The Framework of Research Priorities in COVID Rehabilitation includes five priorities that span health and disability across COVID-19 and Long COVID illness trajectories: (1) understanding experiences of episodic disability; (2) assessing episodic disability; (3) identifying and examining safe approaches to rehabilitation; (4) examining the role, implementation, and impact of models of rehabilitation care; and (5) examining access to safe, timely and appropriate rehabilitation and other health care provider services. The Framework identifies target populations, methodological considerations, and highlights the importance of integrated knowledge translation and exchange in advancing scientific evidence, clinical education, practice, and COVID rehabilitation policy. CONCLUSIONS: This Framework provides a foundation to advance COVID, disability and rehabilitation research to advance the health and well-being of persons with COVID-19, Long COVID, and their caregivers.Implications for rehabilitationPersons with COVID-19 or Long COVID and their caregivers may experience multi-dimensional forms of disability spanning physical, cognitive, emotional health challenges, difficulties with daily function, and social inclusion, which individually and/or collectively may be unpredictable, episodic and/or chronic in nature.Rehabilitation has a role in preventing or mitigating disability and enhancing health outcomes for persons with COVID-19, Long COVID and their caregivers.The Framework of Research Priorities COVID Rehabilitation includes five overlapping research priorities spanning health and disability across COVID trajectories: (1) understanding experiences of episodic disability; (2) assessing episodic disability; (3) identifying and examining safe approaches to rehabilitation; (4) examining the role, implementation, and impact of models of rehabilitation care; and (5) examining access to safe, timely and appropriate rehabilitation and other health care provider services.The research priorities in the Framework represent a comprehensive approach to examine disability and rehabilitation across COVID illness trajectories and the broad continuums of rehabilitation care to provide a coordinated and collaborative approach to advancing evidence in COVID disability and rehabilitation.This Framework provides a foundation for international and interdisciplinary collaborations, to advance COVID disability and rehabilitation research to enhance health outcomes of persons with COVID-19, Long COVID, and their caregivers.
