HIV Epidemiology75IMPACT SIGNAL
Global surveillance evidence

A 1.39-million-sample map of HIV-1 shows the diversity diagnostics and vaccines must keep pace with

The study assembled 1,395,222 HIV-1 subtype observations from 154 countries between 1990 and 2024 and weighted country estimates using UNAIDS numbers of people living with HIV. In 2020-24, subtype C represented 48.7% globally, followed by subtype A at 11.5% and subtype B at 10.3%. Unique and circulating recombinant forms were also substantial. Regional patterns differed sharply: subtype C dominated southern Africa and south Asia, CRF01_AE southeast Asia, and CRF07_BC increased in east Asia.

Unconfirmed emerging signal

DESI DR2 hints at evolving dark energy, but the evidence remains inconclusive

The analysis combined DESI DR2 baryon acoustic oscillations with three Type Ia supernova compilations and a compressed CMB likelihood across eight dark-energy parameterizations. Several models favored the w0 > -1, wa < 0 region and crossed the phantom divide near z about 0.5. However, the preference was driven mainly by the limited LRG1-2 tracers. Mirage-model Bayes factors were only inconclusive to moderate, and no model was robustly preferred by late-time data alone.

Laboratory mechanistic evidence

Oxygen-vacancy engineering at Cu-Zn interfaces advances low-temperature methanol synthesis

Cu/ZnO catalysts for low-temperature methanol synthesis from CO2-containing syngas suffer activity and stability limits. Adding Ba regulated oxygen vacancies at Cu-Zn interfaces, reaching a TOF of 21.2 × 10^-3 s^-1 and methanol space-time yield of 655.17 g kgcat^-1 h^-1. Ba increased exposed Cu0 area, dispersion and basic sites while suppressing sintering. DFT supported interfacial oxygen vacancies as primary active sites.

Qualitative systems evidence

Longitudinal aging data in Asia face funding, workforce and data-sharing bottlenecks

This qualitative study interviewed 33 stakeholders across 13 East and Southeast Asian countries and regions, with additional experts from India, the UK and US. Four themes emerged: structural and contextual barriers; local adaptation of design and logistics; funding and staff-retention threats; and governance, privacy and comparability constraints. Recommendations emphasize policy alignment, multidisciplinary collaboration, harmonization and intentional inclusion of vulnerable populations.

Randomized-trial evidence

Star Homes reduced malaria by 44% and also lowered diarrhea and respiratory infections in children

The trial evaluated the Star Home, a two-story design intended to be insect-proof, cleaner, cooler and smoke-free while providing water and sanitation. Households with children younger than 13 were cluster-randomized to 110 Star Homes or 513 traditional mud and thatched-roof homes. Over three years, children in Star Homes experienced 44% less malaria, 30% less diarrhea and 18% fewer acute respiratory infections; children younger than five also had better height-for-age. The findings support housing as a modifiable determinant of health rather than merely the setting in which disease occurs.

Phase 3 survival evidence

Perioperative enfortumab vedotin plus pembrolizumab improved survival outcomes in bladder cancer

Patients with muscle-invasive bladder cancer who cannot receive cisplatin have had limited perioperative options. This trial randomized 344 participants to enfortumab vedotin plus pembrolizumab before and after surgery or to surgery alone. At two years, event-free survival was 74.7% versus 39.4%, and overall survival 79.7% versus 63.1%. Pathological complete response also differed markedly, but grade 3 or worse adverse events occurred in 71.3% of the combination group.

Systematic review and meta-analysis

Pure autonomic failure phenoconverted to central synucleinopathies at about 5% per year

Pure autonomic failure may precede brain disorders driven by alpha-synuclein. Across nine longitudinal studies and 900 patients followed for a mean 6.4 years, 270 patients (30%) phenoconverted: 12% to MSA, 11% to DLB and 7% to Parkinson disease. The pooled rate was 5.09 per 100 person-years. Hyposmia favored PD/DLB over MSA, while REM sleep behavior disorder and subtle motor signs were consistent predictors of phenoconversion overall.

Field detection and surveillance innovation

CRISPR-BEEPs mapped melioidosis exposure and sanitation gaps in northeast Thailand

Burkholderia pseudomallei is difficult to detect environmentally with conventional culture. CRISPR-BEEPs was benchmarked against plate inspection using double-qPCR as reference. Sensitivity was 93.5% versus 19.4%, with specificity of 100% versus 98.0%. Across 15,118 km² in northeast Thailand, the assay detected the organism in 73.3% of groundwater, 32.9% of surface water and 26.2% of piped-water samples. Detection within 10 km of a household was associated with melioidosis (OR 2.74), an association missed by conventional methods.
