Mapping the cellular biogeography of human bone marrow niches using single-cell transcriptomics and proteomic imaging.

Non-hematopoietic cells are essential contributors to hematopoiesis. However, heterogeneity and spatial organization of these cells in human bone marrow remain largely uncharacterized. We used single-cell RNA sequencing (scRNA-seq) to profile 29,325 non-hematopoietic cells and discovered nine transcriptionally distinct subtypes. We simultaneously profiled 53,417 hematopoietic cells and predicted their interactions with non-hematopoietic subsets. We employed co-detection by indexing (CODEX) to spatially profile over 1.2 million cells. We integrated scRNA-seq and CODEX data to link predicted cellular signaling with spatial proximity. Our analysis revealed a hyperoxygenated arterio-endosteal neighborhood for early myelopoiesis, and an adipocytic localization for early hematopoietic stem and progenitor cells (HSPCs). We used our CODEX atlas to annotate new images and uncovered mesenchymal stromal cell (MSC) expansion and spatial neighborhoods co-enriched for leukemic blasts and MSCs in acute myeloid leukemia (AML) patient samples. This spatially resolved, multiomic atlas of human bone marrow provides a reference for investigation of cellular interactions that drive hematopoiesis.

Rapid in vivo multiplexed editing (RIME) of the adult mouse liver.

BACKGROUND AND AIMS: Assessing mammalian gene function in vivo has traditionally relied on manipulation of the mouse genome in embryonic stem cells or perizygotic embryos. These approaches are time-consuming and require extensive breeding when simultaneous mutations in multiple genes is desired. The aim of this study is to introduce a rapid in vivo multiplexed editing (RIME) method and provide proof of concept of this system. APPROACH AND RESULTS: RIME, a system wherein CRISPR/caspase 9 technology, paired with adeno-associated viruses (AAVs), permits the inactivation of one or more genes in the adult mouse liver. The method is quick, requiring as little as 1 month from conceptualization to knockout, and highly efficient, enabling editing in >95% of target cells. To highlight its use, we used this system to inactivate, alone or in combination, genes with functions spanning metabolism, mitosis, mitochondrial maintenance, and cell proliferation. CONCLUSIONS: RIME enables the rapid, efficient, and inexpensive analysis of multiple genes in the mouse liver in vivo .

Enrollment Trends Among Patients with Melanoma Brain Metastasis in Active Clinical Trials.

The CNS is a common site for distant metastasis and treatment failure in melanoma patients. This study aimed to evaluate the inclusion rate of patients with melanoma brain metastases (MBM) in prospective clinical trials. 69.3% of trials excluded MBM patients based on their CNS disease. In univariate analysis, trials not employing immunotherapy (p = 0.0174), inclusion of leptomeningeal disease (p < 0.0001) and non-pharmaceutical sponsor trials (p = 0.0461) were more likely to enroll patients with MBM. Thoughtful reconsideration of clinical trial designs is needed to give patients with MBMs access to promising investigational agents and improve outcomes for patients with MBM.

Integration of child life into adult oncology: A mixed-methods feasibility study.

BACKGROUND: Cancer in a loved one can have negative effects on child health and development. Child Life Specialists (CLSs) specialize in assisting children understand and cope with difficult medical scenarios but are generally not available in adult care facilities to support the needs of patient-families with minor children. We conducted a mixed-methods study of the implementation of a pilot CLS program at a tertiary oncology centre. METHODS: We collected administrative and clinical data on referred families; encounter data; and patient-reported questionnaire data before and 2 months after engagement with the program. RESULTS: Over the initial 10 months, 98 families were referred, 91 of whom engaged through a total of 257 clinical encounters. The cancer patient in the family was most commonly a woman with a mean age of 45 years and in the role of mother. Breast cancer was the most common diagnosis (24%) and 78% of patients had stage IV disease. Most families had >1 child at home, and children were most commonly school-aged (5-14y). Phone and Hospital/Clinic visits accounted for the largest portion of CLS time. Interventions ranged from diagnosis education through to bereavement support. Most cancer patients indicated that the program was helpful to them and their families. There were trends of moderate improvements on patient reported outcomes. CONCLUSION: Our study was able to provide an understanding of the initial CLS program operations to guide program development and future study. Such a program holds promise as an important aspect of adult oncology family-centered care.

Diagnosis, management, and outcomes of immune checkpoint inhibitor induced acute interstitial nephritis: A single-center experience.

BACKGROUND: Immune checkpoint inhibitor (ICI)-associated acute interstitial nephritis (AIN) is a recognized complication of immunotherapy (IO), but literature on its management and outcomes is limited. METHODS: We retrospectively reviewed patients who received ICIs and developed biopsy-proven or clinically-suspected ICI-associated AIN at the University of Virginia Comprehensive Cancer Center from 2012-2023. We analyzed baseline characteristics and clinical outcomes, including treatment interruption and rechallenge rates. Acute kidney injury (AKI) was defined as a ≥ 1.5-fold increase in baseline creatinine under seven days, a two-fold increase above the upper limit of normal, or an increase by ≥0.3 mg/dL. Kidney function returning to within 0.3 mg/dL or less than twice baseline was considered complete (CRc) and partial (PRc) recovery, respectively. RESULTS: We identified 12 cases of ICI-AIN: four by biopsy (33%) and eight (67%) by clinical suspicion. Two patients received anti-CTLA-4 and anti-PD1, six received anti-PD1 alone, and four received chemo-immunotherapy. The majority (58%) of patients developed AIN within the first 5 cycles. Eight patients developed ≥ Grade 3 AKI, and six developed multiple irAEs. ICI was permanently discontinued in seven patients (58%) and temporarily interrupted in four (30%). The CRc and PRc rates were 67% and 8%, respectively. Upon AIN onset, the best disease response was stable disease in five patients, partial response in three, and progressive disease in three. Median overall survival was 4.87 years, and progression-free survival was 1.5 years. CONCLUSIONS: Rechallenge with IO after kidney irAE may be possible in some patients but requires careful evaluation on an individual basis.

Nasal Airway Volumes are More Asymmetric in Skeletally Mature Patients With Cleft lip and Palate Than Controls on 3-Dimensional Analysis.

BACKGROUND: This study assesses nasal airway volumes in skeletally mature patients with CLP and healthy controls and examines the relationship among nasal volumes, cleft laterality, and facial asymmetry. METHODS: Computed tomography images from patients with CLP and controls were analyzed using Mimics Version 23.0 (Materialise, Leuven, Belgium). Relationships among nasal airway volume, cleft laterality, and facial asymmetry were compared. RESULTS: The 89 patients in this study included 66 (74%) CLP and 23 (17%) controls. Nasal airway volumes in CLP were more asymmetric than controls (26.8±17.5% vs. 17.2±14.4%; P=0.015). In UCLP, the smaller nasal airway was on the cleft side 81% of the time (P<0.001). Maximum airway stenosis was on the cleft side 79% of the time (P<0.001), and maximum stenosis was on the same side as the smaller airway 89% of the time (P<0.001). There was a mild linear relationship between nasal airway asymmetry and maximum stenosis (r=0.247, P=0.023). On 3-dimensional image reconstruction, the septum often bowed convexly into the cleft-sided nasal airway with a caudal deviation towards the noncleft side. Nasal airway asymmetry was not associated with facial midline asymmetry (P>0.05). CONCLUSION: The nasal airway is more asymmetric in patients with cleft lip and palate compared with the general population, with the area of maximum stenosis usually occurring on the cleft-sided airway. In patients with unilateral cleft lip and palate, the septum often bows into the cleft side, reducing the size of that nasal airway. Nasal airway asymmetry did not correlate with facial asymmetry.

Crowdsourcing the Impact of Illustration in Cleft Surgery Education.

OBJECTIVE: This study aimed to (1) assess layperson preferences for how surgical information is presented; (2) evaluate how the format of visual information relates to layperson comfort with undergoing surgery, perceptions of surgeon character traits, and beliefs about artistic skill impacting plastic surgery practice; and (3) identify sociodemographic characteristics associated with these outcomes. DESIGN: A survey was developed in which one of five standardized sets of information depicting a unilateral cleft lip repair was presented as (1) text alone, (2) quick sketches, (3) simple drawings, (4) detailed illustrations, or (5) photographs. SETTING: Online crowdsourcing platform. PARTICIPANTS: Raters aged 18 years and older from the United States. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): After viewing the surgical information, participants answered three sets of Likert scale questions. Ratings were averaged to produce three composite scores assessing (1) comfort with undergoing surgery (2) perceptions of surgeon character traits, and (3) beliefs about plastic surgery and artistry. RESULTS: Four hundred seventy-nine participants were included. Surgeon character traits score was highest among participants who viewed detailed illustrations at 4.46 ± 0.59, followed by photographs at 4.43 ± 0.54, text alone at 4.28 ± 0.59, simple drawings at 4.17 ± 0.67, and quick sketches at 4.17 ± 0.71 (p = 0.0014). Participants who viewed detailed illustrations rated surgical comfort score and plastic surgery and artistry score highest, although differences did not achieve statistical significance. CONCLUSIONS: Viewing detailed cleft lip repair illustrations was significantly associated with positive perceptions of surgeon character traits. Our data help to contextualize methods of communication and education valued by the public when seeking cleft care.

Health-related quality of life in early-stage Hodgkin lymphoma: a longitudinal analysis of the ABVD arm in the randomized controlled trial HD.6.

Early-stage Hodgkin lymphoma has become one of the most curable hematologic malignancies. Depending upon the disease location, possible toxicities, and patient preference, chemotherapy alone with ABVD remains an accepted treatment modality for this disease. There remains a paucity of data regarding the longitudinal trajectory of health-related quality of life (HRQoL) in patients treated for HL. The impact of disease and treatment on HRQoL is increasingly important to understand as the number of long-term survivors increases. We report the longitudinal HRQoL using data prospectively collected from diagnosis up to 10 years post-treatment in the ABVD arm of the HD.6 randomized controlled trial for early-stage HL patients (N=169). We analyzed HRQoL using the EORTC QLQ-C30 collected at baseline, 3 months, 6 months, and 12 months after completion of chemotherapy and yearly up to year 10. Clinically and statistically significant improvements were noted for specific domains including emotional (3 months post-treatment), social (12 months post-treatment) and financial functioning (2 years post-treatment), and the specific symptom of fatigue (6 months post-treatment) during the follow-up period. To our knowledge, this is the first prospective, longitudinal analysis of HRQoL specifically among patients with early-stage HL treated with ABVD therapy alone. Although improvements were noted, sustained clinically and statistically significant improvements were noted only in select symptoms emphasizing the need to better understand and optimize HRQoL among this patient group.

Web-Based Asynchronous Tool to Facilitate Communication Between Primary Care Providers and Cancer Specialists: Pragmatic Randomized Controlled Trial.

BACKGROUND: Cancer poses a significant global health burden. With advances in screening and treatment, there are now a growing number of cancer survivors with complex needs, requiring the involvement of multiple health care providers. Previous studies have identified problems related to communication and care coordination between primary care providers (PCPs) and cancer specialists. OBJECTIVE: This study aimed to examine whether a web- and text-based asynchronous system (eOncoNote) could facilitate communication between PCPs and cancer specialists (oncologists and oncology nurses) to improve patient-reported continuity of care among patients receiving treatment or posttreatment survivorship care. METHODS: In this pragmatic randomized controlled trial, a total of 173 patients were randomly assigned to either the intervention group (eOncoNote plus usual methods of communication between PCPs and cancer specialists) or a control group (usual communication only), including 104 (60.1%) patients in the survivorship phase (breast and colorectal cancer) and 69 (39.9%) patients in the treatment phase (breast and prostate cancer). The primary outcome was patient-reported team and cross-boundary continuity (Nijmegen Continuity Questionnaire). Secondary outcome measures included the Generalized Anxiety Disorder Screener (GAD-7), Patient Health Questionnaire on Major Depression, and Picker Patient Experience Questionnaire. Patients completed the questionnaires at baseline and at 2 points following randomization. Patients in the treatment phase completed follow-up questionnaires at 1 month and at either 4 months (patients with prostate cancer) or 6 months following randomization (patients with breast cancer). Patients in the survivorship phase completed follow-up questionnaires at 6 months and at 12 months following randomization. RESULTS: The results did not show an intervention effect on the primary outcome of team and cross-boundary continuity of care or on the secondary outcomes of depression and patient experience with their health care. However, there was an intervention effect on anxiety. In the treatment phase, there was a statistically significant difference in the change score from baseline to the 1-month follow-up for GAD-7 (mean difference -2.3; P=.03). In the survivorship phase, there was a statistically significant difference in the change score for GAD-7 between baseline and the 6-month follow-up (mean difference -1.7; P=.03) and between baseline and the 12-month follow-up (mean difference -2.4; P=.004). CONCLUSIONS: PCPs' and cancer specialists' access to eOncoNote is not significantly associated with patient-reported continuity of care. However, PCPs' and cancer specialists' access to the eOncoNote intervention may be a factor in reducing patient anxiety.

"There's So Much More Support We Could Have Provided": Child Life Specialists' Stories of the Challenges Working in Adult Oncology.

A cancer diagnosis in patients who are parents of minor children is uniquely stressful for both parents and children. Children need developmentally appropriate information and support to help reduce their fears and worries. Child life specialists (CLSs) are health professionals who work in pediatric environments to support children and families with the stress and uncertainty of illnesses. Increasingly, CLSs have been called upon to support children of patients in adult clinical environments. Our objective was to elucidate CLS caregiving narratives related to working with children of adult cancer patients. We used narrative inquiry to interview four CLSs working in adult oncology. Canadian CLSs who have experience providing care for children and families affected by parental cancer were recruited via convenience sampling. We used narrative analysis methods that included multiple close reads of the data, generating narrative themes, and noting conflicts or tensions in the data. CLSs' caregiving stories often highlighted the complexities of working in an adult oncology environment. Their narratives included challenges in providing optimal care to the children, including family-level barriers (such as parental wishes to withhold information from their children) and systemic barriers (such as late referrals and limited options for bereavement support). CLS participants identified several challenges of working with families in adult oncology. The CLSs highlighted a desire for additional institutional support for children of adult oncology patients and for themselves working in these environments in order to achieve what they believed to be optimal care.

AKT but not MYC promotes reactive oxygen species-mediated cell death in oxidative culture.

Oncogenes can create metabolic vulnerabilities in cancer cells. We tested how AKT (herein referring to AKT1) and MYC affect the ability of cells to shift between respiration and glycolysis. Using immortalized mammary epithelial cells, we discovered that constitutively active AKT, but not MYC, induced cell death in galactose culture, where cells rely on oxidative phosphorylation for energy generation. However, the negative effects of AKT were temporary, and AKT-expressing cells recommenced growth after ∼15 days in galactose. To identify the mechanisms regulating AKT-mediated cell death, we used metabolomics and found that AKT-expressing cells that were dying in galactose culture had upregulated glutathione metabolism. Proteomic profiling revealed that AKT-expressing cells dying in galactose also upregulated nonsense-mediated mRNA decay, a marker of sensitivity to oxidative stress. We therefore measured levels of reactive oxygen species (ROS) and discovered that galactose-induced ROS exclusively in cells expressing AKT. Furthermore, ROS were required for galactose-induced death of AKT-expressing cells. We then confirmed that galactose-induced ROS-mediated cell death in breast cancer cells with upregulated AKT signaling. These results demonstrate that AKT but not MYC restricts the flexibility of cancer cells to use oxidative phosphorylation.This article has an associated First Person interview with the first author of the paper.

Cancer specialist perspectives on implementing an online communication system with primary care providers.

Context: The Canadian Team to Improve Community-Based Cancer Care along the Continuum (CanIMPACT) is a group of researchers, primary care providers (PCPs), cancer specialists, patients and caregivers working to improve cancer care coordination between PCPs and cancer specialists. Previous research by CanIMPACT and others has identified problems related to communication, coordination, and continuity of care. Objective: Describe findings from qualitative interviews with cancer specialists on implementation of an online communication system with PCPs. Study Design: Hybrid type I effectiveness-implementation study that included a qualitative research component and a pragmatic RCT. Setting: Ottawa Hospital Cancer Program and primary care practices in the Champlain region. Population Studied: Cancer specialists (nurses, medical and radiation oncologists, program administrators). Interviews conducted with 12 cancer specialists. Intervention: Cancer-specific adaptation of Champlain BASE™ eConsult, an online communication system for PCPs and cancer specialists called "eOncoNote". For patients receiving treatment for prostate or breast cancer, cancer specialists had an opportunity to participate in eOncoNote discussion with PCP for 4-6 months; for breast and colorectal cancer survivors, the eOncoNote discussion lasted for 1 year post discharge to the patient's PCP. Results: Cancer specialists described limited PCP involvement in cancer care while patients received active treatment, with one-way communication and notes being "sent into a vacuum". There was more communication with PCPs regarding patients with metastatic disease, comorbid conditions, after patients have completed treatment, or during palliative care. Patients and caregivers play a critical role in coordinating cancer care, helping to facilitate coordination. Lack of access to the same electronic medical record (EMR) among healthcare providers poses a barrier to cancer care coordination. eOncoNote had the potential to be useful tool but it was not used extensively. Conclusions: Accessing eOncoNote as a separate system was challenging to incorporate into the workflow, and cancer specialists highlighted the need for integration with their EMR. eOncoNote did not affect information sharing with PCPs, as there was limited uptake within primary care.

Does the type of biopsy used for diagnosis impact subsequent treatment selection in prostate cancer patients?

PURPOSE: Multiparametric magnetic resonance imaging (mpMRI) targeted biopsy has emerged as an augmentation to systematic prostate biopsy (SBx) with improved diagnostic accuracy. The purpose of this study was to determine whether biopsy modality impacted management of prostate cancer (PCa). METHODS: We performed a retrospective review of patients with newly diagnosed non-metastatic PCa at our institution (2014-2020). Either ultrasound-guided 12-core SBx or SBx plus ≥1targeted biopsy cores from identifiable lesions on mpMRI were performed. Patients were managed with active surveillance (AS), radiation therapy (RT), or radical prostatectomy (RP). Multivariate logistic and multinomial regression analyses were performed. RESULTS: Of 578 patients, 221(38%) proceeded with AS, 121(21%) received RT, and 236(41%) underwent RP. Median age and prostate-specific antigen (PSA) were 65.4 years and 7.2 ng/mL, respectively. On multivariate analysis, biopsy type did not predict decision to pursue treatment (p=.951). On multinomial regression analysis, biopsy type did not predict selection of AS over RP (p=.973) or RT over RP (p=.813). Alternatively, age, grade group, and PSA were significant predictors of management selection. CONCLUSIONS: Biopsy technique did not impact management for patients with new PCa diagnosis. Despite paradigm shifts in obtaining tissue diagnosis, age, PSA, and grade group remain valuable indices for shared decision-making and counseling patients with PCa.

Hitting the Vasopressor Ceiling: Finding Norepinephrine Associated Mortality in the Critically Ill.

BACKGROUND: There is no consensus on what dose of norepinephrine corresponds with futility. The purpose of this study was to investigate the maximum infusion and cumulative doses of norepinephrine associated with survival for patients in medical and surgical intensive care units (MICU and SICU). MATERIALS AND METHODS: A retrospective review was conducted of 661 critically ill patients admitted to a large academic medical center who received norepinephrine. Univariate, multivariate, and area under the curve analyses with optimal cut offs for maximum infusion rate and cumulative dosage were determined by Youden Index. RESULTS: The population was 54.9% male, 75.8% white, and 58.7 ± 16.1 y old with 384 (69.8%) admitted to the MICU and 166 (30.2%) admitted to the SICU, including 38 trauma patients. Inflection points in mortality were seen at 18 mcg/min and 17.6 mg. The inflection point was higher in MICU patients at 21 mcg/min and lower in SICU patients at 11 mcg/min. MICU patients also had a higher maximum cumulative dosage of 30.7 mg, compared to 2.7 mg in SICU patients. In trauma patients, norepinephrine infusions up to 5 mcg/min were associated with a 41.7% mortality rate. CONCLUSION: A maximum rate of 18 mcg/min and cumulative dose of 17.6 mg were the inflection points for mortality risk in ICU patients, with SICU patients tolerating lower doses. In trauma patients, even low doses of norepinephrine were associated with higher mortality. These data suggest that MICU, SICU, and trauma patients differ in need for, response to, and outcome from escalating norepinephrine doses.

I'm here because I was told to come: a study of cancer patients' reasons for attending the emergency department.

OBJECTIVES: Patients with cancer are seen frequently in emergency departments (EDs). It has been proposed that many of these visits are preventable, but the patient perspective has not been well-studied. METHODS: We conducted structured interviews with a convenience sample of patients who presented to a single ED with a cancer-related complaint. We asked standardized questions regarding patient predisposing characteristics, enabling factors (e.g., access to support), and perceived need for care. We compared the reported perceived need with the evaluated need by ED healthcare providers. Themes were identified using descriptive content analysis. RESULTS: Forty-five patients completed interviews, of whom 30 (67%) were admitted to hospital. The most frequent reasons for seeking ED care were pain (includes abdominal) (33%), fever (11%), and weakness (11%). The majority (77%) did not make the decision to go to the ED alone: healthcare providers (40%, most commonly oncologists) and caregivers (36%) were the reported decision-makers in these cases. The majority (73%) felt their ED visit was not preventable. Themes of an alternative oncological setting for tests, improved community services, and both earlier medication management and referral to specialist care were identified from patients who reported their visit was avoidable. Congruence between (patient) perceived need and evaluated need was high (96%). CONCLUSIONS: The minority of patients made the decision to seek ED care by themselves. While the majority did not believe emergency care was avoidable, those who did had cogent suggestions to that end. Patient's assessments of their own need had high agreement with ED providers' evaluations.

Integration of patient-reported outcomes (PROs) for personalized symptom management in "real-world" oncology practices: a population-based cohort comparison study of impact on healthcare utilization.

BACKGROUND: The use of patient-reported outcomes (PROs) for routine cancer distress screening is endorsed globally as a quality-care standard. However, there is little research on the integration of PROs in "real-world" oncology practices using implementation science methods. The Improving Patient Experience and Health Outcome Collaborative (iPEHOC) intervention was established at multisite disease clinics to facilitate the use of PRO data by clinicians for precision symptom care. The aim of this study was to examine if patients exposed to the intervention differed in their healthcare utilization compared with contemporaneous controls in the same time frame. METHODS: We used a PRE- and DURING-intervention population cohort comparison study design to estimate the effects of the iPEHOC intervention on the difference in difference (DID) for relative rates (RR) for emergency department (ED) visits, hospitalizations, psychosocial oncology (PSO), palliative care visits, and prescription rates for opioids and antidepressants compared with controls. RESULTS: A small significantly lower Difference in Difference (DID) (- 0.223) in the RR for ED visits was noted for the intervention compared with controls over time (0.947, CI 0.900-0.996); and a DID (- 0.0329) for patients meeting ESAS symptom thresholds (0.927, CI 0.869-0.990). A lower DID in palliative care visits (- 0.0097), psychosocial oncology visits (- 0.0248), antidepressant prescriptions (- 0.0260) and an increase in opioid prescriptions (0.0456) in the exposed population compared with controls was also noted. A similar pattern was shown for ESAS as a secondary exposure variable. CONCLUSION: Facilitating uptake of PROs data may impact healthcare utilization but requires examination in larger scale "real-world" trials.

Patient-reported symptoms following mastectomy alone or lumpectomy plus radiation for early stage breast cancer: a cohort study.

PURPOSE: Studies examining symptom differences between surgeries for breast cancer patients rarely incorporate the effects of adjuvant treatment choice. We sought to understand differences in patient-reported symptoms between lumpectomy plus radiation and mastectomy in the year following surgery. METHODS: This cohort study used linked administrative datasets. The exposure was defined as lumpectomy plus radiation or mastectomy. The outcomes of moderate-to-severe (score ≥ 4) patient-reported symptoms were obtained using the Edmonton symptom assessment system (ESAS). Line plots were created to determine symptom trajectories in the 12 months following surgery, and the relationships between surgery and each of the nine symptoms were assessed using multivariable analyses. Clinical significance was determined as a difference of 10%. RESULTS: Of 13,865 Stage I-II breast cancer patients diagnosed 2007-2015, 11,497 underwent lumpectomy plus radiation and 2368 underwent mastectomy. Symptom trajectories were similar for all nine symptoms until approximately 5 months postoperatively when they diverged and mastectomy symptoms started becoming more severe. On multivariable analyses, patients undergoing mastectomy were at an increased risk of reporting moderate-to-severe depression (RR 1.19, 95% CI 1.09-1.30), lack of appetite (RR 1.11, 95% CI 1.03-1.20), and shortness of breath (RR 1.16, 95% CI 1.04-1.15) compared to those undergoing lumpectomy plus radiation. CONCLUSIONS: Even with the addition of adjuvant radiation, patients who are treated with lumpectomy fare better in three of nine patient-reported symptoms. Further examination of these differences will assist in better shared decision-making regarding surgical treatments.

Moving Cancer Care Ontario's Exercise for People with Cancer guidelines into oncology practice: using the Theoretical Domains Framework to validate a questionnaire.

Evidence supporting the benefits of exercise surrounding cancer treatment has led to internationally published guidelines, with minimal uptake by oncology care providers (OCPs). There is a need to understand how to implement research evidence into practice. Our team developed a questionnaire to assess OCPs' knowledge of exercise guidelines and barriers/facilitators to exercise counseling and program referral. We validated the questionnaire using the Theoretical Domains Framework, a knowledge translation (KT) framework used to implement evidence-based guidelines into practice. In this commentary, we describe this process and the rationale for integrating a KT framework into intervention development and implementation in oncology practice. The revised questionnaire, entitled Clinicians Perspectives on Exercise in Patients with Cancer (CliPEC), is shared to facilitate the implementation process and allow for comparison across oncology practices.

The "Patient-centered coordination by a care team" questionnaire achieves satisfactory validity and reliability.

Increasing prevalence of chronic conditions and multimorbidity challenges health care systems and calls for patient-centered coordination of care. Implementation and evaluation of health policies focusing on the development of patient-centered coordination of care needs valid instruments measuring this dimension of care. The aim of this validation study was to assess the psychometric properties of the French version of the 14-item Patient-Centered Coordination by a Care Team (PCCCT) questionnaire in a primary care setting. PCCCT provides a total score from 0 (worst coordination) to 42 (best coordination). 165 adult patients consulting in primary care with one or more chronic condition(s) completed questionnaires (including PCCCT) at recruitment. After three weeks, participants completed PCCCT again, either by mail (group A) or during a telephone interview (group B). At recruitment, the mean (SD) PCCCT score was 33.3 (7.7). Exploratory factor analysis revealed a 2-dimension structure, 8 items relating to patient involvement and 6 items relating to coordination (factors loadings ranging from 0.34 to 0.88). PCCCT score correlated significantly with subscales of Haggerty's continuity questionnaire, Spearman correlation coefficients (95% confidence interval) ranging from 0.40 (0.22-0.57) to 0.52 (0.38-0.63). Internal consistency was excellent: Cronbach alpha 0.90 (0.79-0.92). Reliability was good, with an intraclass correlation coefficient of 0.68 (0.55-0.78) for test-retest reliability (group A) and of 0.65 (0.46-0.79) for reliability between the self-administered and the interviewer-administered versions of the questionnaire (group B,). The PCCCT questionnaire presents satisfactory validity and reliability; it can be used for the evaluation of health organizations involving team work in primary care.
