Summary
Construct Validity and Inter-Rater Reliability of a Tool Designed for Nurses
[Posted 17/Jan/2023]
AUDIENCE: Nursing
KEY FINDINGS: The surgical wound assessment tool was deemed to be acceptable, valid and reliable for monitoring the status of surgical wound healing. However, further modification and testing are needed to strengthen the tool and to determine the applicability of the tool in other populations.
BACKGROUND: Purpose of this study is to validate construct validity and inter-rater reliability of a surgical wound assessment tool. Wound assessment is central to appropriate wound management. However, limited standard surgical wound assessment tools are available to assist nurses in assessing and recording progress in the healing of surgical wounds.
DETAILS: A prospective observational study was utilised to test the validity and reliability. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guideline was used. Convenience sampling was used to recruit 260 patients who underwent elective or emergency surgery at a hospital in Vietnam. Exploratory factor analysis was used to examine the construct validity of the surgical wound assessment tool. Inter-rater reliability was calculated using the intraclass correlation coefficient and Cohen's kappa to determine reliability of the overall scale and identified items. The results of the exploratory factor analysis supported a three-component structure of the surgical wound assessment tool. The intraclass correlation coefficient value of the overall scale was 0.79 (95% CI 0.67-0.89), p < .001, confirming excellent inter-rater reliability. Cohen's kappa value ranged from 0.5 to 1, demonstrating moderate to almost perfect level of agreement for individual items, except for one item on pain.

AI-Assisted Colonoscopy for Colorectal Lesion Detection in Lynch Syndrome
A multicentre randomized trial of 733 patients with Lynch syndrome found that AI-assisted colonoscopy did not significantly increase adenoma detection compared with high-definition white-light colonoscopy alone (33.8% vs 30.9%; P=0.41). AI-based lesion characterization showed good sensitivity and specificity but did not clearly improve on expert optical diagnosis in specialized surveillance settings.
KEY FINDINGS: In this international randomized trial conducted at specialized Lynch syndrome surveillance centres, adding AI-assisted detection to high-definition white-light colonoscopy did not significantly increase adenoma detection. Although the CADx system demonstrated good sensitivity and specificity for lesion differentiation, it did not clearly provide an advantage over expert optical diagnosis in this specialist setting. The findings indicate that the benefit of AI-assisted colonoscopy may depend on the expertise and clinical setting in which it is deployed.
BACKGROUND: Individuals with Lynch syndrome undergo regular colonoscopic surveillance because of their increased risk of colorectal cancer. Artificial intelligence (AI)-based computer-aided detection (CADe) has improved adenoma detection in average-risk colorectal cancer screening, but evidence in Lynch syndrome surveillance has been limited. The CADLY2 trial evaluated whether AI-assisted colonoscopy could improve adenoma detection and whether computer-aided optical diagnosis (CADx) could accurately differentiate neoplastic from non-neoplastic colorectal lesions.
DETAILS: This international, multicentre, open-label, randomized controlled trial was conducted at nine specialized hereditary cancer surveillance centres in Belgium, Germany, the Netherlands, and Spain. Adults aged 18 years or older with genetically confirmed Lynch syndrome undergoing surveillance colonoscopy were randomly assigned to high-definition white-light (HD-WL) colonoscopy alone or HD-WL colonoscopy assisted by the CAD EYE AI system. CADe was used during withdrawal to identify lesions, while CADx was used after lesion detection to assist with optical differentiation. The primary outcome was adenoma detection rate, defined as the proportion of patients with at least one histopathologically confirmed adenoma.

Between May 9, 2023, and October 30, 2025, 757 patients were randomly assigned to HD-WL colonoscopy (377) or AI-assisted colonoscopy (380). The primary analysis included 733 patients: 369 in the HD-WL group and 364 in the AI-assisted group. Adenoma detection occurred in 30.9% of patients undergoing HD-WL colonoscopy compared with 33.8% receiving AI-assisted colonoscopy. The odds ratio was 1.14 (95% CI, 0.83-1.57; P=0.41), indicating no statistically significant improvement in adenoma detection with CADe. In the lesion-level analysis, CADx differentiated neoplastic from non-neoplastic lesions with a sensitivity of 85.9% (95% CI, 82.0-89.1) and specificity of 91.4% (95% CI, 89.4-93.0). Three adverse events occurred in the AI-assisted group, including two mild post-polypectomy bleeding events and one serious pulmonary embolism or deep venous thrombosis considered unrelated to the procedure. No adverse events were reported in the HD-WL group.

Exercise Therapy and Education Improve Short-Term Outcomes After ACL Reconstruction
A randomized trial of 184 young adults with persistent knee symptoms after ACL reconstruction found that 4 months of supervised exercise and education produced greater short-term improvements in pain, function, and quality of life than minimal education and self-directed exercise. Benefits narrowed by 12 months, while no difference in cartilage thickness was observed between groups.
KEY FINDINGS: In young adults with persistent knee symptoms after ACL reconstruction, a 4-month supervised exercise and education program produced greater short-term improvements in knee pain, symptoms, function, and quality of life than minimal education and self-directed exercise. The treatment difference diminished by 12 months, and no difference in cartilage thickness was observed, providing trial evidence that the supervised exercise program did not result in detectable adverse changes in this structural measure over the study period. The findings support the potential value of structured rehabilitation for patients who continue to experience knee problems after the usual postoperative rehabilitation period.
BACKGROUND: Persistent pain, functional limitations, and reduced quality of life can continue in young adults after anterior cruciate ligament reconstruction (ACLR), increasing concern about early post-traumatic knee osteoarthritis. The SUPER-Knee randomized clinical trial evaluated whether a structured, physiotherapist-supervised exercise and education program could improve knee symptoms and function in young adults with ongoing problems after ACLR, while also examining whether exercise affected knee cartilage.
DETAILS: The randomized clinical trial enrolled 184 adults aged 18 to 40 years who remained symptomatic 9 to 36 months after ACL reconstruction. Participants were randomly assigned to either a 4-month individualized program of twice-weekly, physiotherapist-supervised strengthening and neuromuscular exercise with education or a minimal-intervention group receiving a one-time education session and advice for self-directed exercise. The primary outcome was change in the Knee injury and Osteoarthritis Outcome Score (KOOS4), which incorporates pain, symptoms, function in sports and recreational activities, and knee-related quality of life. Secondary outcomes included patient-perceived recovery, thigh muscle strength, and MRI measures of cartilage.

Of the 184 participants, 92 were assigned to each group; 178 participants (97%) completed the 4-month assessment and 174 (95%) completed the 12-month assessment. At 4 months, KOOS4 scores improved by 14.1 points in the supervised exercise group compared with 9.3 points in the minimal-intervention group, corresponding to an adjusted between-group difference of 4.8 points (95% CI, 1.4 to 8.2). The difference was smaller at 12 months, with an adjusted between-group difference of 1.4 points (95% CI, -2.0 to 4.8). Participants receiving supervised exercise also had greater improvements in thigh muscle strength and were more likely to report that their knee had improved. The odds of reporting improvement were 5.2 times higher at 4 months (95% CI, 2.7 to 10.0) and 2.5 times higher at 12 months (95% CI, 1.3 to 4.9). MRI assessment showed no between-group difference in cartilage thickness.

Palliative Extracorporeal Membrane Oxygenation Decannulation: An Ethical, Evidence-Based Approach
A structured approach to ECMO de-escalation and decannulation can reduce practice variability while incorporating patient and family preferences. Proactive symptom management may improve the patient and family experience, supporting a more comfortable and dignified end-of-life journey.
KEY FINDINGS: A structured, interprofessional approach to palliative ECMO de-escalation can reduce variability in end-of-life practice and support more consistent symptom management and communication. Incorporating patient and family preferences into the process, together with proactive symptom management and staff debriefing, was associated with a more comfortable and dignified end-of-life experience in this quality-improvement setting.
BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is an invasive, potentially lifesaving therapy associated with complications involving multiple organ systems. When ECMO is no longer considered beneficial, de-escalation or decannulation may be required as part of a transition to comfort-focused care and natural death. At a tertiary care facility with 64 beds using ECMO, variability was identified in ECMO initiation, communication with patients and families, determination of nonbeneficial therapy, and symptom management during de-escalation.
DETAILS: This quality-improvement project integrated palliative care, reviewed existing literature on best practices, and established an interprofessional task force focused on ECMO de-escalation. New clinical guidelines were developed to provide a consistent, evidence-based framework for communication, decision-making, symptom management, and de-escalation/decannulation. The initiative was designed to reduce practice variability while improving the experience of patients, families, and clinicians during transition to comfort-directed care.

Implementation of the guidelines decreased practice variability and reduced patient and family stress and discomfort during ECMO de-escalation and decannulation. Team members reported decreases in symptoms of secondary trauma and moral distress associated with these situations. They also reported improved delivery of end-of-life care, including family education and support, patient advocacy, and symptom management. Family members valued greater attention to both patient and family well-being, while structured staff debriefings supported reflection and identification of opportunities for improvement.

Real-World Study Finds No Significant Difference in Heart Failure Risk Between Biosimilar and Reference Trastuzumab
In real-world practice, trastuzumab biosimilars were not associated with a statistically significant increase in heart failure compared with reference trastuzumab, supporting their cardiac safety. However, older age, anthracycline use, and greater comorbidity burden remain important risk factors, and larger studies are needed to assess cardiac safety differences among individual biosimilars.
KEY FINDINGS: In this large real-world cohort of patients with early-stage HER2-positive breast cancer, biosimilar trastuzumab use increased markedly between 2018 and 2024 without a statistically significant difference in heart failure risk compared with reference trastuzumab. Overall heart failure occurred in 5.9% of the study population. Comorbidity burden and older age were associated with higher heart failure risk, emphasizing the importance of cardiovascular risk assessment during HER2-directed therapy. Because this was a retrospective claims-based study, longer follow-up and additional real-world studies are needed to further evaluate long-term cardiac outcomes.
BACKGROUND: Trastuzumab is an important treatment for HER2-positive breast cancer, but cardiac dysfunction, including heart failure, remains a recognized safety concern. Biosimilar trastuzumab products have expanded treatment access and may reduce costs, although real-world data comparing their cardiac safety with the reference product remain limited. This study evaluated the uptake of biosimilar trastuzumab and compared heart failure risk between patients receiving biosimilar and reference trastuzumab in routine clinical practice.
DETAILS: The investigators analyzed patients aged ≥18 years with breast cancer who received trastuzumab between 2018 and 2024 using the IQVIA PharMetrics Plus Closed Health Plan Claims database. Patients who underwent breast cancer surgery within the first year after diagnosis were considered to have early-stage disease. Individuals with a heart failure diagnosis before breast cancer surgery were excluded. Trastuzumab products were identified using Healthcare Common Procedure Coding System Level II codes, while heart failure was identified using International Classification of Diseases codes. The analysis used multivariable cause-specific Cox proportional hazards regression to evaluate the association between trastuzumab type and subsequent heart failure risk. The study included 5,135 patients, of whom 43.9% received reference trastuzumab.

Use of biosimilar trastuzumab increased substantially during the study period, from 0% in 2018 to 71.3% in 2024 (P<0.001). Overall, heart failure occurred in 5.9% of patients, including 5.5% of those receiving reference trastuzumab and 6.3% of those receiving biosimilar trastuzumab (P=0.26). After adjustment for relevant factors, there was no statistically significant difference in heart failure risk between biosimilar and reference trastuzumab (adjusted HR, 1.16; 95% CI, 0.92-1.46). In contrast, patients with a Charlson Comorbidity Index score ≥2 had a higher heart failure risk than those with a score of 0 (adjusted HR, 1.52; 95% CI, 1.11-2.08). Older age was also associated with greater risk: compared with patients aged 18-54 years, the adjusted HR was 1.61 (95% CI, 1.19-2.19) for those aged 65-74 years and 1.95 (95% CI, 1.29-2.96) for those aged ≥75 years.

Formononetin May Protect Against Anthracycline Cardiotoxicity Through Cardiac Metabolic Improvement
A preclinical study identified ERRa as an early metabolic regulator of anthracycline-induced cardiotoxicity, with its reduction occurring before overt cardiac dysfunction. Formononetin, an ERRa activator, improved cardiac metabolism and function in mouse and pig models while also enhancing doxorubicin's anticancer activity in breast cancer organoids. The findings suggest a potential dual-action strategy for protecting the heart during anthracycline therapy, but clinical studies are still needed.
KEY FINDINGS: The findings identify ERRα downregulation as an early and potentially causal component of anthracycline-induced cardiac injury. Formononetin improved cardiac energy metabolism and function in experimental models while retaining, and potentially enhancing, doxorubicin's anticancer activity in breast cancer organoids. The study therefore suggests that pharmacologic activation of ERRα could represent a future strategy for simultaneously addressing anthracycline cardiotoxicity and cancer treatment. However, the evidence remains preclinical, and clinical studies are required to determine whether these findings translate into cardioprotection in patients receiving anthracycline chemotherapy.
BACKGROUND: Anthracyclines such as doxorubicin are effective anticancer agents, but their use can be limited by anthracycline-induced cardiotoxicity (AIC). Early metabolic disturbances in cardiac muscle may contribute to the development of cardiac dysfunction. This study investigated the role of estrogen-related receptor α (ERRα), a regulator of cardiac energy metabolism, in AIC and evaluated whether pharmacologic activation of ERRα with formononetin could provide cardiac protection while maintaining anticancer activity.
DETAILS: The investigators used a porcine model of anthracycline cardiotoxicity to examine changes in ERRα over time and cardiomyocyte-specific gain- and loss-of-function mouse models to assess its functional role. Mechanistic experiments, including ChIP-qPCR, reporter assays, and microscale thermophoresis, were used to investigate how formononetin interacts with the ERRα pathway. Cardiac tissue from patients who had received chemotherapy was also examined, while human breast cancer patient-derived organoids were used to evaluate potential effects on tumor activity. ERRα expression was reduced in hearts from the porcine AIC model and in cardiac tissue from patients treated with chemotherapy. In pigs, the reduction occurred at the 6-week subclinical stage, before overt cardiac dysfunction developed. Increasing ERRα expression specifically in cardiomyocytes enhanced mitochondrial metabolic programs and fatty-acid oxidation and preserved systolic function after doxorubicin exposure, whereas ERRα reduction worsened metabolic dysfunction and cardiac impairment.

Drug screening identified formononetin as a selective ERRα activator. In mouse and pig models, formononetin increased ERRα activity, improved cardiac mitochondrial metabolism, and reduced anthracycline-associated cardiac injury. Mechanistic experiments indicated that formononetin interacts with the ERRα/PGC-1α complex and promotes its stability, supporting activation of downstream metabolic pathways.
Importantly, formononetin also demonstrated anticancer activity in human breast cancer patient-derived organoids. Treatment with formononetin alone reduced organoid viability and proliferation, while combining formononetin with doxorubicin produced greater antitumor effects.
