Endovascular thrombectomy for patients with large-core ischaemic stroke presenting up to 24 h after onset (ATLAS): a systematic review and individual patient data meta-analysis with central imaging adjudication

The authors aimed to evaluate the efficacy and safety of endovascular thrombectomy in patients with large-core ischaemic stroke presenting within 24 hours of onset, a group often excluded from such treatments. Their systematic review and meta-analysis of individual patient data from six trials found that endovascular thrombectomy significantly improved functional outcomes and reduced mortality compared to medical management, although the benefits were less clear for patients with very large ischaemic core volumes (≥150 mL). Overall, the findings suggest that endovascular thrombectomy is beneficial for most patients with large-core ischaemic strokes, except in cases of extensive ischaemic changes presenting beyond 6 hours.

Enpatoran, a Toll-like receptor 7/8 inhibitor, in moderate-to-severe systemic lupus erythematosus: findings from Cohort B of a multicentre, international, double-blind, placebo-controlled dose-finding phase 2 trial

This study aimed to evaluate the efficacy and safety of enpatoran, a TLR7/8 inhibitor, in improving disease activity in patients with moderate-to-severe systemic lupus erythematosus (SLE) compared to placebo. Although enpatoran showed improved British Isles Lupus Assessment Group-based Composite Lupus Assessment (BICLA) response rates at various doses, the primary objective of demonstrating a statistically significant dose-response relationship was not achieved. Overall, enpatoran was well tolerated among participants.

Impact of introducing RTS,S/AS01_E malaria vaccine on mortality in young children in Ghana, Kenya, and Malawi: an observational evaluation of a cluster-randomised implementation programme

This study evaluates the impact of the RTS,S/AS01_E malaria vaccine on mortality rates in young children in Ghana, Kenya, and Malawi over a 46-month period following its introduction in 2019. The authors aimed to determine whether the vaccine significantly reduced overall mortality in children eligible for three doses compared to non-eligible children, finding a notable reduction in mortality, with approximately one in eight deaths averted in areas with moderate vaccine coverage. The results underscore the importance of accelerating malaria vaccine deployment in regions where malaria remains a leading cause of child mortality.

The role of community-based blood pressure screening in improving hypertension care

The authors argue against the viewpoint that mass blood pressure screening detracts from hypertension care, positing instead that community-based screening can enhance hypertension detection, especially in underserved populations. They emphasize that such screening, when conducted with validated methods, can effectively identify individuals with elevated blood pressure and raise awareness about hypertension, ultimately supporting better management and control of the condition. The paper advocates for integrating community screening with primary care to address the global challenge of hypertension.

Long-term effects of colonoscopy screening on colorectal cancer incidence and mortality: a multicountry, population-based randomised controlled trial

This study aimed to evaluate the long-term effects of colonoscopy screening on colorectal cancer incidence and mortality over a 13-year follow-up period. The results indicated that screening significantly reduced the incidence of colorectal cancer but did not show a corresponding reduction in mortality, with both groups experiencing lower-than-expected mortality rates. The findings suggest that while colonoscopy screening is effective in lowering cancer incidence, its impact on mortality may be less pronounced than anticipated.

Daraxonrasib in Previously Treated Advanced <em>RAS</em>-Mutated Pancreatic Cancer

This study investigates the safety and efficacy of daraxonrasib, a multiselective RAS inhibitor, in patients with previously treated advanced RAS-mutated pancreatic ductal adenocarcinoma (PDAC). The results indicate that while 96% of patients experienced treatment-related adverse events, daraxonrasib demonstrated antitumor activity, with objective response rates of 35% in patients with RAS G12 mutations and 29% in those with other RAS mutations. The findings suggest potential benefits of daraxonrasib in this challenging patient population, warranting further investigation.

Combined Oral Ivermectin and 5% Permethrin Cream to Treat Severe Scabies

The authors aimed to determine whether a higher dose of oral ivermectin (400 μg/kg) combined with 5% permethrin cream is more effective than the standard dose (200 μg/kg) in curing severe scabies. In a randomized trial involving 132 adults, they found no significant difference in cure rates between the two dosing regimens, with 75% in the higher-dose group and 82% in the standard-dose group achieving cure. The study concluded that the higher dose of ivermectin does not provide superior efficacy compared to the standard dose when used with permethrin cream.

Cerebral Amyloid Angiopathy

This article by Steven M. Greenberg examines cerebral amyloid angiopathy (CAA), a significant cause of hemorrhagic stroke and cognitive decline, and seeks to address the challenges in diagnosing and managing the condition. The authors highlight the need for improved risk prediction tools, early diagnostic markers, and potential therapeutic targets to better manage the high risk of recurrent strokes associated with CAA. Ongoing research aims to enhance understanding of the disease's pathology and inform treatment strategies.

Efficacy and Safety of an mRNA Seasonal Influenza Vaccine in Adults

The authors aimed to evaluate the efficacy and safety of an investigational mRNA-based seasonal influenza vaccine, mRNA-1010, in adults aged 50 and older. The phase 3 trial demonstrated that mRNA-1010 was superior to a standard-dose comparator vaccine in preventing RT-PCR-confirmed influenza-like illness, with a relative vaccine efficacy of 26.6%. While mRNA-1010 was associated with more frequent mild to moderate adverse reactions, serious adverse events were similar between the two groups.

Depression

The authors examine the global burden of depression, which affects individuals across all age groups and societies. They emphasize the need for improved diagnosis and clinical management of depression, alongside the development of new interventions, to enhance treatment efficacy and efficiency. The paper seeks to address how existing treatments can be better utilized to combat this pervasive illness.
