Abstract Artificial intelligence is spreading through public health agencies and healthcare systems faster than workforces are trained to govern it. We describe RHAMI (Responsible Health AI Readiness and Maturity Index), the first human-centered automated composite index for health organizations to score AI readiness and maturity as one measurable system of science, economics and ethics, and the physician certification-to-Master’s pathway built to teach what it measures—both designed jointly by frontline public health professionals, clinicians, ethicists, engineers, leaders, and policy-makers in low- and middle-income countries and high-income countries.

Abstract Background Multi-modality therapy has improved survival for many patients with brain metastases. However, neurocognitive sequelae remain a challenge. While advances in radiotherapy have reduced toxicity, the potential interaction with targeted therapy and immunotherapy and the consequent impact on neurocognitive outcomes remain poorly defined. We appraised the current evidence on neurocognitive outcomes in the era of modern combined-modality therapy. Methods This systematic review adhered to PRISMA guidelines and included clinical trials reporting neurocognitive outcomes in patients with brain metastases receiving radiotherapy ± concurrent systemic therapies. Studies published through December 31, 2024 were identified through PubMed/Medline, EMBASE, and Web of Science using pre-defined MeSH term-based search strings. Results 39 studies from 1997-2024 involving 6,617 patients met inclusion criteria (n = 27 whole-brain radiotherapy [WBRT]; n = 12 radiosurgery), including six studies evaluating combined-modality therapy in 1,161 patients. Baseline cognitive evaluation was performed inconsistently, but neurocognitive deficits were frequently observed prior to treatment. Most randomized trials reported improved cognitive outcomes and quality of life with advanced radiotherapy techniques (e.g., hippocampal avoidance, radiosurgery) vs WBRT. Among 20 randomized trials comparing radiotherapy with or without a concurrent investigational systemic therapy, only four included neurocognitive assessments. There was no evidence of cognitive sequelae with combined-modality therapy, though evaluable trials were limited due to inconsistent reporting of neurocognitive functioning. Conclusion As survival improves in patients with brain metastases, preserved cognition is an important outcome measure. The lack of neurocognitive endpoints in pivotal brain metastasis trials represents a critical evidence gap. The interaction between radiotherapy and novel systemic therapies, and their combined effects on neurocognition, remain unknown. To address this, we recommend 1) integrating sensitive, pragmatic, and tailored neurocognitive assessments into oncology trials to quantify additive toxicity, 2) early and systematically incorporating neuropsychology into care pathways, 3) expanding radiation dose-sparing and radioprotective strategies, and 4) evaluating the utility of cognitive rehabilitation programs.

Abstract Introduction Patients with metastatic spine disease (MSD) present with varying degrees of systemic illness and frailty. Given the palliative intent of surgery and radiation treatment for MSD, treatment risks must be judiciously weighed against potential benefits. We sought to examine the impact of peroperative nutritional status as measured by the PG-SGA on survival in patients undergoing surgery and radiation for MSD. Methods This study involved an international, multicenter prospective, observational registry of patients with MSD: AO Knowledge Forum Tumor’s Metastatic Tumor Research and Outcomes Network (MTRON). Variables including baseline demographics, oncologic data, adverse events (medical adverse events and surgical complications), length of stay, and nutritional status were prospectively collected. The Patient-Generated Subjective Global Assessment (PG-SGA) was used to evaluate nutritional status. Results A total of 589 patients were included in this study; 469 (80%) of whom underwent surgery and radiation and 120 (20%) of whom underwent radiation alone. The majority of patients (362, 61%) were classified as well nourished, however, 68 patients (12%) were classified as severely malnourished. Among patients that underwent surgery and radiation, the median overall survival of well nourished patients was 491 days compared to 117 days in the severely malnourished patients (p < 0.001). A multivariate analysis demonstrated severe malnourishment and ECOG performance status of 3 or 4 were associated with worse overall survival. Conclusion Malnutrition as measured by the PG-SGA demonstrated to be significantly and independently associated with perioperative survival in patients with MSD. Further studies that investigate optimal pre-treatment optimization for patients with MSD in order to mitigate morbidity and mortality risk are essential.

Abstract Introduction As the incidence of metastatic spine disease (MSD) increases, treatments to manage refractory pain, pathologic vertebral body fractures, and spinal cord compression are becoming increasingly common. Given the palliative nature of surgical intervention used to achieve tumor control and thus mitigate loss of neurologic function and compromised ambulatory function, it is essential to mitigate the risk of such procedures. Methods The AO Spine Knowledge Forum Tumor’s Metastatic Tumor Research and Outcomes Network (MTRON), an international, prospective registry for patients with spinal metastases, was used for this query. Prospective collection included baseline health and demographic information, oncologic data (including Spinal Instability Neoplastic Score (SINS) score and Bilksy epidural compression classification), and baseline functional status (preoperative American Spinal Injury Association (ASIA) and ECOG scores). Health related quality of life (HRQoL) data included Spine Oncology Study Group Outcomes Questionnaire (SOSGOQ2.0) and Euro-QoL measures. Surgery related adverse events (AE’s) were collected using the Spine Adverse Events Severity (SAVES V2) framework. Kaplan-Meir curves were used to assess survival. Results The cohort consisted of 1267 patients, 701 male (55.3%). A total of 245 (19.3%) experienced at least one postoperative AE, the majority of which were considered minor (grade 3 or less). Among the most common were deep wound infections (3.2%), wound dehiscence (2.5%), and urinary infections (2.4%). A multivariate analysis demonstrated that age, smoking status, ECOG performance, prior radiotherapy, presence of multiple metastases at other sites, and multiple spine metastases were significant risk factors for a postoperative AE. Postoperative AE’s (p = 0.049) and major postoperative AE’s (p = 0.0038) were found to be related to survival as well as a significant change in HRQoL scores (p < 0.001). Conclusion Postoperative AE’s are extremely relevant to the care of patients with MSD and impact both HRQoL and survival.

BACKGROUND: With evolving therapy for heart failure with reduced ejection fraction, the benefits of adding a defibrillator in patients undergoing cardiac resynchronization therapy (CRT) remain unclear, particularly for nonischemic cardiomyopathy (NICM). This study evaluates long-term survival among patients with NICM treated with CRT defibrillator (CRT-D) versus CRT pacemaker (CRT-P). METHODS: DECIDE-CRT (Cardiac Resynchronization With or Without Defibrillator in Non-Ischemic Cardiomyopathy) is a multicenter cohort study across 170 US Veterans Affairs hospitals. We identified patients with NICM receiving primary-prevention CRT-P or CRT-D between January 1, 2006, and December 31, 2020. Using a propensity score approach, we applied inverse probability of treatment weighting to balance baseline characteristics between the CRT-P and CRT-D groups. An inverse probability of treatment weighting–weighted Cox model estimated hazards for all-cause mortality. Secondary outcomes included generator replacement, device-related infections, hospitalization for heart failure, and ventricular arrhythmias. RESULTS: Of 16 609 CRT recipients, 3965 met NICM primary-prevention criteria (CRT-D=3158; CRT- P =807). At baseline, patients with NICM receiving CRT-P were much older, with more cardiovascular and noncardiovascular comorbidities compared with the CRT-D group. During the median follow-up of 5.2 years, the mortality rate for CRT-P versus CRT-D was 9.46 versus 9.21 per 100 person-years (RR, 0.97 [95% CI, 0.71–1.13]; P =0.66). The adjusted hazard ratio for all-cause mortality using the inverse probability of treatment weighting-Cox model was 0.90 (95% CI, 0.71–1.13; P =0.34). There was no difference in adjusted hazard for heart failure hospitalization (hazard ratio, 1.27 [95% CI, 0.86–1.87]), while the CRT-D group had higher rates of generator replacement and device-related infections. CONCLUSIONS: This nationwide observational study from the Veterans Affairs Health system did not demonstrate a clear survival advantage with the addition of a defibrillator among patients with NICM receiving CRT although residual confounding cannot be excluded. Given the uncertainty surrounding the incremental benefit of the defibrillator in this setting, a randomized trial is needed to test the incremental value of CRT-D over CRT-P in NICM.

The Impella 5.5 is an axillary mechanical circulatory support device used in patients with cardiogenic shock, but those with small left ventricular (LV) cavities may be at risk for suction events, hemolysis, malpositioning, hypoperfusion, and LV injury. Informally accepted guidelines, extrapolated from durable LVAD studies, suggest a minimum left ventricular internal dimension in diastole (LVIDd) of 58 mm, with some clinical practices using a more stringent ≤52 mm cutoff. We retrospectively analyzed 154 consecutive patients supported with Impella 5.5 between January 2020 and December 2024. Overall, 38 patients had an LVIDd ≤58 mm, and 116 had an LVIDd >58 mm; a key subgroup of 21 patients presented with a very small LVIDd of ≤52 mm]. Baseline demographics, comorbidities, body mass index, and renal function were similar [across groups], although those with larger LVIDd had lower ejection fractions (16% vs. 24%, p = 0.001). Median support duration was 24 days in all groups, and pre- and post-implant hemodynamic and laboratory improvements were comparable. Rates of transplantation (79% vs. 90%, p = 0.088) and LVAD implantation (2% vs. 6%, p = 0.159) did not differ significantly in the ≤58 mm cohort. Notably, within the ≤52 mm subgroup, 90-day survival remained high at 90.5% ( p = 0.336), with significant improvements in right atrial pressure (17 to 10 mmHg, p = 0.041), mean pulmonary artery pressure (36 to 26 mmHg, p = 0.008), and eGFR (45 to 57 mL/min/1.73m 2 , p = 0.003). Remarkably, native cardiac recovery was observed exclusively in the smaller LV cohorts, occurring in 11% of the ≤58 mm group ( p = 0.003 vs. 0%, p = 0.003) and reaching 19% in the ≤52 mm group (vs. 0% in larger cavities, p < 0.001), while durable LVAD escalation was entirely avoided in the ≤52 mm cohort (0% vs. 6%). Ninety-day event-free survival was excellent across all cohorts 92% vs. 96% in the primary analysis, with no major device-related complications, suction events, clinically significant hemolysis, bleeding, stroke, or escalation to Bi-VAD support. These findings strongly support the safety and feasibility of Impella 5.5 in extremely constrained, small LV cavities.

Pediatric sarcomas are a heterogeneous group of rare mesodermal malignancies. These cancers, which affect children from infancy through adolescence and young adulthood, are in general challenging to treat with currently available therapies. Biologically, many are characterized by quiet genomes, fusion oncoproteins, immune “cold” microenvironments, and vast epigenetic deregulation that contributes to diverse and complex mechanistic drivers. Multifaceted advancements in research strategies, including high-throughput screening, new model systems, surfaceome profiling, and study of oncogenic fusion condensates have led to new opportunities for understanding the biology of pediatric sarcomas. To continue to make progress for these difficult to treat cancers, it will be critical to continue to improve access to bioinformatic data, approach patient care using innovative clinical trial frameworks, and foster interdisciplinary partnerships among medicinal chemists, scientists, clinicians, advocates, and industry partners.

Abstract Background Complications such as intermittent pouchitis (IP) and chronic inflammatory disorders of the pouch (CP) are common after ileal pouch-anal anastomosis (IPAA), particularly among patients with both ulcerative colitis and primary sclerosing cholangitis (PSC). There are no standardized approaches for prophylaxis against these complications for patients with PSC undergoing IPAA. We compared outcomes among patients with PSC and IPAA who received antibiotic or immunosuppressive therapies to those who did not. Methods We designed a retrospective cohort study that included patients with ulcerative colitis and PSC from 7 tertiary care centers that underwent IPAA between 1994 and 2023. Patients were categorized on whether they received medications following IPAA that may provide primary prophylactic benefit, such as antibiotics, probiotics, immunomodulators, or biologic medications; and the proportion of patients developing IP and CP was evaluated. Results A total of 172 patients were included in the cohort, and 13 (7.6%) patients received antibiotics or immunosuppressant medications. Antibiotics and probiotics were the most common therapy (5 patients, 2.9%), followed by biologics, small-molecule inhibitors, immunomodulators, or mesalamine (all 1 patient, 0.6%). Compared to patients not receiving antibiotics or immunosuppression, patients receiving antibiotics or immunosuppression were significantly less likely to develop IP (69.2% vs 91.2%; P = .03; odds ratio 0.22; 95% CI, 0.06-0.80) and CP (23.1% vs 56.0%, P = 0.04; OR 0.24, 95% CI, 0.06-0.89). Conclusions In this retrospective cohort of patients with ulcerative colitis and PSC undergoing IPAA, usage of concomitant antibiotics or immunosuppression was low. However, use of concomitant antibiotics or immunosuppression may decrease the burden of inflammatory conditions of the pouch in these high-risk patients.
