- BACKGROUND: We investigated cancer risk among patients with multiple sclerosis (MS) and whether variation by age at MS diagnosis helps to elucidate mechanisms underlying the previously reported reduced cancer risk. We also studied cancer risk among parents to ascertain if MS susceptibility genes may confer protection against cancer in relatives. METHODS: Cox proportional hazards regression, adjusted for age, sex, area, and socioeconomic index, estimated cancer risk among 20,276 patients with MS and 203,951 individuals without MS, using Swedish general population register data. Similar analyses were conducted among 11,284 fathers and 12,006 mothers of patients with MS, compared with 123,158 fathers and 129,409 mothers of controls. RESULTS: With an average of 35 years of follow-up, there was a decreased overall cancer risk among patients with MS (hazard ratio = 0.91, 0.87-0.95). Increased risks were observed for brain tumors (1.44, 1.21-1.72) and urinary organ cancer (1.27, 1.05-1.53). Parents of patients with MS did not have a notably increased or decreased overall cancer risk. CONCLUSIONS: The reduction in cancer risk in patients with multiple sclerosis (MS) may result from behavioral change, treatment, or we speculate that some immunologic characteristics of MS disease activity improve antitumor surveillance. The lack of association among parents indicates that a simple inherited characteristic is unlikely to explain the reduced cancer risk among patients with MS. MS is associated with increased risk for some cancers, such as of urinary organs and brain tumors (although surveillance bias may be responsible).

- Background and objectives: Cardiovascular disease contributes significantly to disease burden among many Indigenous populations. However, data on stroke incidence in Indigenous populations are sparse. We aimed to investigate what is known of stroke incidence in Indigenous populations of countries with a very high Human Development Index (HDI), locating the research in the broader context of Indigenous health.Methods: We identified population-based stroke incidence studies published between 1990 and 2022 among Indigenous adult populations of developed countries using PubMed, Embase, and Global Health databases, without language restriction. We excluded non-peer-reviewed sources, studies with fewer than 10 Indigenous people, or not covering a 35- to 64-year minimum age range. Two reviewers independently screened titles, abstracts, and full-text articles and extracted data. We assessed quality using "gold standard" criteria for population-based stroke incidence studies, the Newcastle-Ottawa Scale for risk of bias, and CONSIDER criteria for reporting of Indigenous health research. An Indigenous Advisory Board provided oversight for the study.Results: From 13,041 publications screened, 24 studies (19 full-text articles, 5 abstracts) from 7 countries met the inclusion criteria. Age-standardized stroke incidence rate ratios were greater in Aboriginal and Torres Strait Islander Australians (1.7-3.2), American Indians (1.2), Sámi of Sweden/Norway (1.08-2.14), and Singaporean Malay (1.7-1.9), compared with respective non-Indigenous populations. Studies had substantial heterogeneity in design and risk of bias. Attack rates, male-female rate ratios, and time trends are reported where available. Few investigators reported Indigenous stakeholder involvement, with few studies meeting any of the CONSIDER criteria for research among Indigenous populations.Discussion: In countries with a very high HDI, there are notable, albeit varying, disparities in stroke incidence between Indigenous and non-Indigenous populations, although there are gaps in data availability and quality. A greater understanding of stroke incidence is imperative for informing effective societal responses to socioeconomic and health disparities in these populations. Future studies into stroke incidence in Indigenous populations should be designed and conducted with Indigenous oversight and governance to facilitate improved outcomes and capacity building.

- Objective: To assess the efficacy, safety, and tolerability of adjunctive brivaracetam (BRV), a selective, high-affinity ligand for SV2A, for treatment of partial-onset (focal) seizures (POS) in adults. Methods: Data were pooled from patients (aged 16-80 years) with POS uncontrolled by 1 to 2 antiepileptic drugs receiving BRV 50, 100, or 200 mg/d or placebo, without titration, in 3 phase III studies of BRV (NCT00490035, NCT00464269, and NCT01261325, ClinicalTrials.gov, funded by UCB Pharma). The studies had an 8 -week baseline and a 12 -week treatment period. Patients receiving concomitant levetiracetam were excluded from the efficacy pool. Results: In the efficacy population (n = 1,160), reduction over placebo (95% confidence interval) in baseline-adjusted POS frequency/28 days was 19.5% (8.0%-29.6%) for 50 mg/d (p = 0.0015), 24.4% (16.8%-31.2%) for 100 mg/d (p < 0.00001), and 24.0% (15.3%-31.8%) for 200 mg/d (p < 0.00001). The >50% responder rate was 34.2% (50 mg/d, p 0.0015), 39.5% (100 mg/d, p < 0.00001), and 37.8% (200 mg/d, p = 0.00003) vs 20.3% for placebo (p < 0.01). Across the safety population groups (n = 1,262), 90.0% to 93.9% completed the studies. Treatment -emergent adverse events (TEAEs) were reported by 68.0% BRV overall (n 803) and 62.1% placebo (n = 459). Serious TEAEs were reported by 3.0% (BRV) and 2.8% (placebo); 3 patients receiving BRV and one patient receiving placebo died. TEAEs in >5% patients taking BRV (vs placebo) were somnolence (15.2% vs 8.5%), dizziness (11.2% vs 7.2%), headache (9.6% vs 10.2%), and fatigue (8.7% vs 3.7%). Conclusions: Adjunctive BRV was effective and generally well tolerated in adults with POS.
