Treatment Outcomes of Patients with Ependymoma Receiving Radiotherapy: A Single Institution Experience.

INTRODUCTION: The study explored the failure pattern and clinical outcomes in patients with ependymoma undergoing radiotherapy. METHODS: Between January 2004 and June 2022, we included 32 patients with ependymoma who underwent radiotherapy as part of the multimodality treatment at our institution. Of these, 27 (84.4%) underwent adjuvant radiotherapy, four received radiotherapy after local recurrence, and one received definitive CyberKnife radiotherapy (21 Gy in three fractions). The median prescribed dose was 54 Gy in patients who received conventional radiotherapy. We analyzed the local progression-free survival (LPFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), overall survival (OS), and potential prognostic factors. RESULTS: The median age was 29.8 years. Approximately 28.1% were pediatric patients. Fifteen tumors (46.9%) were World Health Organization (WHO) grade II, 10 (31.3%) were WHO grade III, and seven (22.8%) were WHO grade I. Among them, 15 patients (46.9%) had posterior fossa tumors, 10 (31.3%) had supratentorial tumors, and seven (22.8%) had spinal tumors. Of the 31 patients who underwent upfront surgical resection, 19 (61.3%) underwent gross total resection or near total resection. Seventeen of 19 patients with first failures (89.5%) had isolated local recurrences. Of the 19 patients with disease progression, 11 (57.9%) were disease-free or had stable disease after salvage therapy, and five (26.3%) had disease-related mortality. Most of the first local recurrences after radiotherapy occurred in the infield (13 of 16, 81.3%). The 5-year LPFS, DMFS, PFS, and OS rates were 48.5%, 89.6%, 45.1%, and 88.4%, respectively, at a median follow-up of 6.25 years. Subtotal resection was associated with poorer LPFS and PFS in patients with intracranial ependymoma (hazard ratio = 3.69, p = 0.018 for LPFS; hazard ratio = 3.20, p = 0.029 for PFS). CONCLUSION: Incorporating radiotherapy into multimodal treatment has led to favorable outcomes in patients with ependymoma, and the extent of resection is a prognostic factor for the local control of intracranial ependymoma.

Pericytes contribute to pulmonary vascular remodeling via HIF2α signaling.

Vascular remodeling is the process of structural alteration and cell rearrangement of blood vessels in response to injury and is the cause of many of the world's most afflicted cardiovascular conditions, including pulmonary arterial hypertension (PAH). Many studies have focused on the effects of vascular endothelial cells and smooth muscle cells (SMCs) during vascular remodeling, but pericytes, an indispensable cell population residing largely in capillaries, are ignored in this maladaptive process. Here, we report that hypoxia-inducible factor 2α (HIF2α) expression is increased in the lung tissues of PAH patients, and HIF2α overexpressed pericytes result in greater contractility and an impaired endothelial-pericyte interaction. Using single-cell RNAseq and hypoxia-induced pulmonary hypertension (PH) models, we show that HIF2α is a major molecular regulator for the transformation of pericytes into SMC-like cells. Pericyte-selective HIF2α overexpression in mice exacerbates PH and right ventricular hypertrophy. Temporal cellular lineage tracing shows that HIF2α overexpressing reporter NG2+ cells (pericyte-selective) relocate from capillaries to arterioles and co-express SMA. This novel insight into the crucial role of NG2+ pericytes in pulmonary vascular remodeling via HIF2α signaling suggests a potential drug target for PH.

Practice- and System-Based Interventions to Reduce COVID-19 Transmission in Primary Care Settings: A Qualitative Study.

Using qualitative interviews with 68 family physicians (FPs) in Canada, we describe practice- and system-based approaches that were used to mitigate COVID-19 exposure in primary care settings across Canada to ensure the continuation of primary care delivery. Participants described how they applied infection prevention and control procedures (risk assessment, hand hygiene, control of environment, administrative control, personal protective equipment) and relied on centralized services that directed patients with COVID-19 to settings outside of primary care, such as testing centres. The multi-layered approach mitigated the risk of COVID-19 exposure while also conserving resources, preserving capacity and supporting supply chains.

A pneumonectomy model to study flow-induced pulmonary hypertension and compensatory lung growth.

In newborns, developmental disorders such as congenital diaphragmatic hernia (CDH) and specific types of congenital heart disease (CHD) can lead to defective alveolarization, pulmonary hypoplasia, and pulmonary arterial hypertension (PAH). Therapeutic options for these patients are limited, emphasizing the need for new animal models representative of disease conditions. In most adult mammals, compensatory lung growth (CLG) occurs after pneumonectomy; however, the underlying relationship between CLG and flow-induced pulmonary hypertension (PH) is not fully understood. We propose a murine model that involves the simultaneous removal of the left lung and right caval lobe (extended pneumonectomy), which results in reduced CLG and exacerbated reproducible PH. Extended pneumonectomy in mice is a promising animal model to study the cellular response and molecular mechanisms contributing to flow-induced PH, with the potential to identify new treatments for patients with CDH or PAH-CHD.

Reasons for ineligibility for clinical trials of patients with medication-resistant epilepsy.

Selection criteria for clinical trials for medication-resistant epilepsy are used to limit variability and to ensure safety. However, it has become more challenging to recruit subjects for trials. This study investigated the impact of each inclusion and exclusion criterion on medication-resistant epilepsy clinical trial recruitment at a large academic epilepsy center. We retrospectively identified all patients with medication-resistant focal or generalized onset epilepsy who attended an outpatient clinic over a consecutive 3-month period. We assessed each patient's eligibility for trials with commonly required inclusion and exclusion criteria to evaluate the proportion of eligible patients and the most common reasons for exclusion. Among 212 patients with medication-resistant epilepsy, 144 and 28 patients met the criteria for focal or generalized onset epilepsy, respectively. Overall, 9.4% (n = 20) patients were eligible for trials (19 focal onset and one generalized onset). Most patients were excluded from the study due to insufficient seizure frequency (58% of focal onset, 55% of generalized onset). A small proportion of patients with medication-resistant epilepsy were eligible for trials based on common selection criteria. These eligible patients may not be representative of the general population of patients with medication-resistant epilepsy. Insufficient seizure frequency was the most common reason for exclusion.

A contiguous de novo genome assembly of sugar beet EL10 (Beta vulgaris L.).

A contiguous assembly of the inbred 'EL10' sugar beet (Beta vulgaris ssp. vulgaris) genome was constructed using PacBio long-read sequencing, BioNano optical mapping, Hi-C scaffolding, and Illumina short-read error correction. The EL10.1 assembly was 540 Mb, of which 96.2% was contained in nine chromosome-sized pseudomolecules with lengths from 52 to 65 Mb, and 31 contigs with a median size of 282 kb that remained unassembled. Gene annotation incorporating RNA-seq data and curated sequences via the MAKER annotation pipeline generated 24,255 gene models. Results indicated that the EL10.1 genome assembly is a contiguous genome assembly highly congruent with the published sugar beet reference genome. Gross duplicate gene analyses of EL10.1 revealed little large-scale intra-genome duplication. Reduced gene copy number for well-annotated gene families relative to other core eudicots was observed, especially for transcription factors. Variation in genome size in B. vulgaris was investigated by flow cytometry among 50 individuals producing estimates from 633 to 875 Mb/1C. Read-depth mapping with short-read whole-genome sequences from other sugar beet germplasm suggested that relatively few regions of the sugar beet genome appeared associated with high-copy number variation.

Clinicopathologic analysis of conjunctivochalasis and paste-pinch-cut conjunctivoplasty for management.

OBJECTIVE: To correlate the histopathologic results of conjunctival specimens with clinical findings in patients with conjunctivochalasis and report the results of the paste-pinch-cut technique for management. DESIGN: Retrospective chart review. SETTING: Single tertiary ophthalmological centre (Ocular Surface Diseases and Dry Eye Clinic, Wilmer Eye Institute, Johns Hopkins University School of Medicine, Baltimore, Md.). METHODS: Twenty-five patients (32 eyes) with clinically significant conjunctivochalasis. All patients were referred for clinically significant dry eye without previous diagnosis of chalasis. Sixteen patients had an underlying inflammatory systemic condition. Intervention or Observation Procedure(s): Patients underwent surgery with paste-pinch-cut technique. Subjective dry eye symptoms and ocular surface staining scores (corneal and conjunctival staining using fluorescein and lissamine green respectively) were assessed at every visit. MAIN OUTCOME MEASURES: Change in patient symptoms and ocular surface staining scores and histopathologic findings in conjunctival specimens. RESULTS: After surgery, significant improvement was achieved in dry-eye symptoms as well as both corneal and conjunctival staining scores in 29 eyes on reduced topical therapy. Only 3 eyes had persisting conjunctival lissamine staining. Light microscopic examination disclosed mild to moderate lymphoplasmocytic inflammation of the conjunctivae with areas of epithelial goblet cell loss, squamous metaplasia, stromal edema, and fibrosis. CONCLUSION: Conjunctivochalasis appears to be associated with significant inflammation in the setting of dry eye and underlying inflammatory systemic conditions. Although topical anti-inflammatory treatment could be attempted in the initial management, surgical excision should be considered in the absence of clinical response.

Impact of the community eligibility provision program on school meal participation in Texas.

OBJECTIVE: To estimate the impact of opting into the community eligibility provision (CEP) on school meal participation among students in Texas. DESIGN: A quasi-experimental design using a two-way fixed effects panel difference-in-difference model and the variation in adoption timing to estimate the impact of opting into CEP on student breakfast and lunch participation in eligible, ever-adopting schools. SETTING: All public and charter K-12 schools in Texas participating in national school meals (breakfast and/or lunch) from 2013 to 2019 who are eligible for the CEP program in at least 1 year and choose to opt into the program in at least 1 year (n 2797 unique schools and 16 103 school-years). PARTICIPANTS: School-level administrative data from the Texas Department of Agriculture on meal counts, enrollment and summary characteristics of students merged with district-level educational and socio-demographic data from the Texas Education Authority. RESULTS: We find opting into CEP increased school breakfast participation by 4·59 percentage points (P < 0·001) and lunch participation by 4·32 percentage points (P < 0·001), on average. The effect is slightly larger (4·64 and 4·61, respectively) and still statistically significant when excluding summer months. CONCLUSION: Our findings suggest that opting into CEP modestly increases school meal participation in Texas, with a similar impact on breakfast and lunch.

Development of a primary care pandemic plan informed by in-depth policy analysis and interviews with family physicians across Canada during COVID-19: a qualitative case study protocol.

INTRODUCTION: Given the recurrent risk of respiratory illness-based pandemics, and the important roles family physicians play during public health emergencies, the development of pandemic plans for primary care is imperative. Existing pandemic plans in Canada, however, do not adequately incorporate family physicians' roles and perspectives. This policy and planning oversight has become increasingly evident with the emergence of the novel coronavirus disease, COVID-19, pandemic. This study is designed to inform the development of pandemic plans for primary care through evidence from four provinces in Canada: British Columbia, Newfoundland and Labrador, Nova Scotia, and Ontario. METHODS AND ANALYSIS: We will employ a multiple-case study of regions in four provinces. Each case consists of a mixed methods design which comprises: (1) a chronology of family physician roles in the COVID-19 pandemic response; (2) a provincial policy analysis; and (3) qualitative interviews with family physicians. Relevant policy and guidance documents will be identified through targeted, snowball and general search strategies. Additionally, these policy documents will be analysed to identify gaps and/or emphases in existing policies and policy responses. Interviews will explore family physicians' proposed, actual and potential roles during the pandemic, the facilitators and barriers they have encountered throughout and the influence of gender on their professional roles. Data will be thematically analysed using a content analysis framework, first at the regional level and then through cross-case analyses. ETHICS AND DISSEMINATION: Approval for this study has been granted by the Research Ethics of British Columbia, the Health Research Ethics Board of Newfoundland and Labrador, the Nova Scotia Health Authority Research Ethics Board and the Western University Research Ethics Board. Findings will be disseminated via conferences and peer-reviewed publications. Evidence and lessons learnt will be used to develop tools for government ministries, public health units and family physicians for improved pandemic response plans for primary care.

Preoperative patient-reported outcome score thresholds predict the likelihood of reaching MCID with surgical correction of adult spinal deformity.

BACKGROUND CONTEXT: Preoperative (pre-op) identification of patients likely to achieve a clinically meaningful improvement following surgery for adult spinal deformity (ASD) is critical, especially given the substantial cost and comorbidity associated with surgery. Even though pain is a known indication for surgical ASD correction, we are not aware of established thresholds for baseline pain and function to guide which patients have a higher likelihood of improvement with corrective surgery. PURPOSE: We aimed to establish pre-op patient-reported outcome measure (PROM) thresholds to identify patients likely to improve by at least one minimum clinically important difference (MCID) with surgery for ASD. STUDY DESIGN: This is a retrospective cohort study using prospectively collected data. PATIENT SAMPLE: We reviewed 172 adult patients' charts who underwent corrective surgery for spinal deformity. OUTCOME MEASURES: Included measures were the Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI), and Scoliosis Research Society-22 (SRS-22). Our primary outcome of interest was improvement by at least one MCID on the ODI and SRS-22 at 2 years after surgery. METHODS: As part of usual care, the VAS, ODI, and SRS-22 were collected pre-op and re-administered at 1, 2, and 5 years after surgery. MCIDs were calculated using a distribution-based method. Determining significant predictors of MCID at two years was accomplished by Firth bias corrected logistic regression models. Significance of predictors was determined by Profile Likelihood Chi-square. We performed a Youden analysis to determine thresholds for the strongest pre-op predictors. RESULTS: At year two, 118 patients (83%) reached MCID for the SRS and 127 (75%) for the ODI. Lower pre-op SRS overall, lower pre-op SRS pain, and higher pre-op SRS function predicted a higher likelihood of reaching MCID on the overall SRS (p < 0.05). Higher pre-op ODI, lower SRS pain and self-image, and higher SRS overall predicted a higher likelihood of reaching MCID on the ODI (p < 0.05). An ODI threshold of 29 predicted reaching MCID with a sensitivity of 0.89 and a specificity of 0.64 (AUC = 0.7813). An SRS threshold of 3.89 predicted reaching MCID with a sensitivity of 0.93 and specificity of 0.68 (AUC = 0.8024). CONCLUSIONS: We identified useful thresholds for ODI and SRS-22 with acceptable predictive ability for improvement with surgery for ASD. Pre-op ODI, SRS, and multiple SRS subscores are predictive of meaningful improvement on the ODI and/or SRS at 2 years following corrective surgery for spinal deformity. These results highlight the usefulness of PROMs in pre-op shared decision-making.

Concurrent primary Sjögren's syndrome and isolated ocular sarcoidosis presenting with bilateral corneal scarring and dry eye.

PURPOSE: To report the case of a patient who presents with multiple progressive ocular diseases who is diagnosed with concurrent primary Sjögren's syndrome and isolated ocular sarcoidosis. OBSERVATION: A 60-year-old woman was referred for dry eye disease, bilateral interstitial keratitis, anterior uveitis, and progressive glaucoma. There was clinical suspicion of an autoimmune etiology due to her ocular history, risk factors, and presentation. Thorough diagnostic testing revealed both primary Sjögren's syndrome and ocular sarcoidosis. After 2.5 years of systemic treatment and follow up, the patient currently remains stable. CONCLUSIONS AND IMPORTANCE: Autoimmune disease may underlie those with progressive ocular disease with an unknown etiology. More than one autoimmune disease may be the cause of ocular findings, especially for patients with a complicated presentation. Proper awareness, clinical suspicion, and diagnosis of these diseases can greatly improve a patient's condition and prevent future ocular and systemic complications.

Design, Adoption, Implementation, Scalability, and Sustainability of Telehealth Programs.

Telehealth and telemedicine services can be a solution for improving accessibility and reducing the cost of health care. Challenges remain in designing, implementing, and sustainably scaling telehealth solutions. Research is lacking on the health impacts and cost-effectiveness of telehealth; more data are needed in the evaluation of telehealth programs, adjusting for potential participant bias and extending the time frame of evaluating impact. In addition, rethinking and addressing the economic incentives and payment for telehealth services, as well as the medical-legal framework for provider competition across geographic regions (and jurisdictions), are needed for greater adoption of telehealth services.

Lymphedema microsurgery improved outcomes of pediatric primary extremity lymphedema.

BACKGROUND: Primary lymphedema is an anomaly of the regional lymphatic system with long symptom duration or severe lymphatic obstruction. Few microsurgical treatments for primary lymphedema have been reported. This aim of this study was to investigate the outcomes of microsurgical treatments in pediatric primary lymphedema patients. METHODS: Between 2013 and 2017, pediatric primary lymphedema patients who underwent either lymphovenous anastomosis (LVA) or vascularized lymph node transfer (VLNT) were retrospectively reviewed. Cheng's Lymphedema Grading, Taiwan Lymphoscintigraphy Staging and indocyanine green lymphography were used to select the procedures. No compression garments were used postoperatively. Outcome measurements included circumferential difference, episodes of cellulitis, and Lymphedema-specific Quality of life questionnaire (LYMQoL). RESULTS: Nine patients with mean age of 9.2 years (range, 2-19 years) with 11 lower and two upper lymphedematous limbs underwent 11 VLNT and two LVA. All VLNT flaps survived. At a mean 38.4-months (range, 16-63 months) of follow-up, the mean circumferential difference in nine unilateral lymphedematous limbs was improved by 6.7 ± 9.9% (p = .066). Two patients with bilateral lower limb lymphedema had mean limb circumference improvements of 1.3 and 6.5 cm, respectively. In nine limbs with cellulitis preoperatively, episodes of cellulitis decreased by 2.67 times/year (p = .007). At a mean 22.3-months of follow-up (range, 13-24 months), the LYMQoL overall score in 6 patients older than 7 years was improved by 3.2 ± 1.1 points (p = .007). CONCLUSIONS: Lymphedema microsurgery significantly improved the episodes of cellulitis and quality of life without utilizing compression garments in pediatric primary lymphedema patients.

Case series: Delayed diagnoses of Acanthamoeba keratitis.

PURPOSE: To describe two cases of Acanthamoeba keratitis in contact lens wearers misdiagnosed as Herpes simplex keratitis. OBSERVATIONS: Case 1 is a 54-year-old male that was misdiagnosed with Herpes simplex keratitis who developed advanced Acanthamoeba keratitis. His treatment course was complex and involved both medical therapy and surgical intervention with poor resolution. Case 2 is an 18-year-old male who was also initially misdiagnosed and treated for Herpes simplex keratitis, but ultimately treated with polyhexamethylene biguanide and chlorhexidine with complete resolution. CONCLUSIONS AND IMPORTANCE: The clinical presentation of Acanthamoeba keratitis may closely resemble other causes of keratitis and continues to be misdiagnosed, leading to delayed diagnosis and treatment. However, given the significant morbidity and challenging treatment course for Acanthamoeba keratitis, it is important for clinicians to maintain a high suspicion for Acanthamoeba and to consider obtaining cultures in contact lens wearers with atypical keratitis prior to making a diagnosis of Herpes simplex keratitis.

An Assessment of Normal Tibiofibular Anatomy on Lateral Fluoroscopy.

BACKGROUND: Intraoperative identification of syndesmotic malreduction during ankle fracture fixation can be challenging. Prior studies describe the normal tibiofibular relationship on anteroposterior and mortise views to aid assessment, but the normal anatomic variation on the lateral view has not been well defined. The aim of this study was to describe the normal anatomy of the lateral radiographic view of the ankle, focusing on the relative position of the fibula and tibial plafond. METHODS: We retrospectively identified consecutive adults undergoing ankle fracture open reduction internal fixation in 2011-2018. Two independent observers assessed the tibiofibular relationship on perfect lateral images of the uninjured side. Measurements were made in pixels, converted into millimeters using published parameters, and averaged for analysis. Reliability was calculated using Pearson correlation coefficients. RESULTS: Of 751 cases of adult ankle fracture fixation identified, 50 patients had perfect lateral images of the contralateral side. In 11 patients (22%), the posterior border of the fibula intersected precisely at the posterior edge of the tibial plafond. Ten patients (20%) had anterior intersections, whereas 29 (58%) had posterior intersections. The intersection was within ±2 mm of the plafond edge in 27 patients (54%). Intrarater reliability was 0.86 and 0.93. Interrater reliability was 0.88. CONCLUSION: In most ankles, the posterior border of the fibula intersects the posterior extent of the tibial plafond within 2 mm. If more than 2 mm away, one should query malreduction, especially if anterior. This method of intraoperative assessment may decrease the occurrence of syndesmotic malreduction. LEVEL OF EVIDENCE: Level III, comparative series.

PROMIS Physical Function Correlates with KOOS, JR in Patients with Knee Pain.

Using Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS PF) computerized adaptive test instead of the Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR) could reduce question burden for patients with knee pain. We aimed to prospectively determine the correlation between PROMIS PF and KOOS, JR to assess whether PROMIS PF could be a useful alternative measure for both research and clinical care of patients with knee pain. This was a cross-sectional study of 88 patients. We assessed the correlation between PROMIS PF and KOOS, JR using a Pearson's correlation test. Two multivariable linear regression models were used to determine the amount of variation explained by various patient-level factors. There was a strong correlation between PROMIS PF and KOOS, JR (r = 0.74, p < 0.001). KOOS, JR was an independent predictor of PROMIS PF when controlling for patient-level factors (ß 0.26; p < 0.001). The results of this study support the idea of using PROMIS PF in place of joint-specific measures such as KOOS, JR for clinical care of patients with knee pain. The level of evidence for this study is Level III.

Arthroscopic Primary Bundle-Specific Posterior Cruciate Ligament Repair with Transosseous Fixation.

Posterior cruciate ligament (PCL) injuries are most commonly associated with multiligamentous knee injuries. Isolated rupture can be treated nonoperatively with bracing, but with concomitant surgical injuries or high-grade instability, operative intervention may be warranted. While historically PCL injuries were surgically managed with open primary repair, contemporary surgical options include arthroscopic primary repair and reconstruction. Appropriate patient selection is critical in avoiding residual laxity following primary repair, and innovations in advanced imaging and arthroscopic technology now allow for identification of suitable patients. In this technical vote, we describe a method for anatomic bundle-specific primary PCL repair with transosseous fixation. The appropriate patient for this procedure has a femoral-sided avulsion of 1 or both PCL bundles, presents with an acute or subacute injury, and has adequate tissue quality for bundle reapproximation to the footprint. This allows for minimally invasive, anatomic restoration of tension for each bundle.

Transcriptional Regulation of the Glucose-6-Phosphate/Phosphate Translocator 2 Is Related to Carbon Exchange Across the Chloroplast Envelope.

The exchange of reduced carbon across the inner chloroplast envelope has a large impact on photosynthesis and growth. Under steady-state conditions it is thought that glucose 6-phosphate (G6P) does not cross the chloroplast membrane. However, growth at high CO2, or disruption of starch metabolism can result in the GPT2 gene for a G6P/Pi translocator to be expressed presumably allowing G6P exchange across the chloroplast envelope. We found that after an increase in light, the transcript for GPT2 transiently increases several 100-fold within 2 h in both the Col-0 and WS ecotypes of Arabidopsis thaliana. The increase in transcript for GPT2 is preceded by an increase in transcript for many transcription factors including Redox Responsive Transcription Factor 1 (RRTF1). The increase in GPT2 transcript after exposure to high light is suppressed in a mutant lacking the RRTF1 transcription factor. The GPT2 response was also suppressed in a mutant with a T-DNA insert in the gene for the triose-phosphate/Pi translocator (TPT). However, plants lacking TPT still had a robust rise in RRTF1 transcript in response to high light. From this, we conclude that both RRTF1 (and possibly other transcription factors) and high amounts of cytosolic triose phosphate are required for induction of the expression of GPT2. We hypothesize that transient GPT2 expression and subsequent translation is adaptive, allowing G6P to move into the chloroplast from the cytosol. The imported G6P can be used for starch synthesis or may flow directly into the Calvin-Benson cycle via an alternative pathway (the G6P shunt), which could be important for regulating and stabilizing photosynthetic electron transport and carbon metabolism.

Influence of Patient Activation, Pain Self-Efficacy, and Resilience on Pain Intensity and Magnitude of Limitations in Patients With Hip and Knee Arthritis.

Studying the relative impact of various measures of coping strategies can help determine which ones are most useful for patients with osteoarthritis (OA).This study prospectively enrolled 108 patients with hip or knee OA who were seeing an orthopedic surgeon before or after arthroplasty. Measures of coping strategies included the Patient Activation Measure (PAM), Pain Self-Efficacy Questionnaire (PSEQ-2), and the Brief Resilience Scale (BRS). The Hip Disability and Osteoarthritis Outcome Score, Junior (HOOS, JR), the Knee Injury and Osteoarthritis Outcome Score, Junior (KOOS, JR), and Numeric Rating Scale (NRS) were used to measure pain intensity. Pearson correlations measured the interrelationships of the outcome measures. The PSEQ-2 correlated significantly with the NRS, but the confidence intervals for the three instruments overlapped. The PAM and the PSEQ-2 correlated with the KOOS, JR. Only the PSEQ-2 was associated with variation in the NRS. The PAM, PSEQ-2, and BRS correlated with one another. While measures of self-efficacy, active involvement in care, and general resilience were correlated, the measure of pain self-efficacy had the strongest association with patient-reported outcomes.
