High-Dose Oral Rifampin Did Not Improve Survival in Tuberculous Meningitis—HARVEST Trial Shows No Benefit and Possible Harm

A multinational randomized trial found that adding high‑dose oral rifampin (total 35 mg/kg for 8 weeks) to standard therapy did not reduce 6‑month mortality in adults with tuberculous meningitis and was associated with more drug‑induced liver injury and earlier deaths in some patients.

ICU Structure and Care Processes Drive VAP and CLABSI Burden in Brazilian ICUs: Insights from the IMPACTO‑MR Nested Cohort

A large multicenter Brazilian cohort found that ICU-level structure and process measures — staffing, prevention protocols, hand hygiene training, visitation policies, and specific clinical roles — explain substantial between-hospital variability and are associated with lower VAP and CLABSI rates.

ICU Structure and Care Processes Explain Much of VAP and CLABSI Variation in Brazilian ICUs: Findings from a 50‑Unit IMPACTO‑MR Nested Cohort

A 50‑ICU nested cohort from the IMPACTO‑MR platform links ICU-level structure and care processes to substantially different ventilator‑associated pneumonia and central line‑associated bloodstream infection rates, highlighting modifiable institutional targets in LMIC intensive care.

Precision Immunotherapy for Sepsis: ImmunoSep Trial Shows Early Organ‑Function Benefit with Targeted Anakinra or IFN‑γ

The ImmunoSep randomized trial found that biomarker-guided immunotherapy (anakinra for macrophage activation‑like syndrome; interferon‑γ for sepsis‑induced immunoparalysis) improved organ dysfunction by day 9 versus placebo, though 28‑day mortality was unchanged. Safety signals require follow‑up.

Novel Type 1 and Type 3 Live Attenuated Oral Poliovirus Vaccines Show Comparable Safety, Immunogenicity, and Shedding to Sabin mOPV in First‑in‑Human Phase 1 Trial

A multicentre phase 1 trial in healthy US adults found nOPV1 and nOPV3 were well tolerated and induced robust homotypic neutralising antibody responses with shedding profiles similar to Sabin monovalent OPV, supporting progression to phase 2 studies.

High Viral Suppression with TLD in PEPFAR Programs — But Resistance and Adherence Signals Require Targeted Action

A multinational prospective cohort found high viral suppression after switching or initiating tenofovir–lamivudine–dolutegravir (TLD), but emergent dolutegravir-resistance was detected in a small subgroup with prior virological failure and poor adherence, highlighting the need for monitoring and adherence support.

Daily High‑Dose Mosnodenvir Significantly Lowers DENV‑3 Viremia in a Human Challenge — Proof‑of‑Concept with Early Resistance Signals

In a phase 2a human challenge, high‑dose daily mosnodenvir substantially reduced DENV‑3 RNA burden versus placebo without serious adverse events, but treatment‑associated NS4B viral mutations emerged, highlighting efficacy and resistance concerns that require larger field studies.

Routine 5–7 Day Antibiotic Prophylaxis After Upper GI Bleeding in Cirrhosis: New Meta-analysis Questions the Mortality Benefit

A 2025 bayesian meta-analysis of 14 RCTs (n=1,322) found shorter or no antibiotic prophylaxis after upper GI bleeding in cirrhosis was highly likely to be noninferior for mortality, though it increased reported bacterial infections. Study limitations temper definitive practice change.

Single-dose Cervarix induces durable seropositivity but fails HPV‑16 GMC non-inferiority versus three-dose Gardasil-4: implications from the PRIMAVERA immunobridging trial

PRIMAVERA immunobridging shows single-dose Cervarix induces near-universal seropositivity at 36 months and non-inferior HPV-18 antibodies versus three-dose Gardasil-4, but HPV-16 antibody GMCs were lower; results inform but do not yet support regulatory single-dose approval.

Bivalent RSV pre‑F Vaccine Dramatically Reduces RSV‑Associated Hospitalisations and Chronic‑Disease Exacerbations in Adults Aged 75–79 Years

In a multicentre test‑negative study of 1006 adults aged 75–79 in England, a bivalent RSV pre‑F vaccine reduced RSV‑associated hospitalisation by 82% overall and protected against severe disease and exacerbations of chronic heart and lung disease, including in immunosuppressed patients.

Three-Month Clofazimine–Rifapentine Regimen for Drug‑Susceptible TB Failed to Improve Outcomes and Raised Safety Concerns: Lessons from Clo‑Fast (Phase 2c)

The Clo‑Fast phase 2c trial tested a 3‑month rifapentine‑clofazimine regimen versus standard 6‑month therapy for drug‑susceptible pulmonary TB. Culture conversion at 12 weeks was similar, but shorter therapy had higher grade ≥3 adverse events and worse 65‑week composite clinical outcomes, leading to early termination.
