A new study conducted by researchers at Massachusetts General Hospital (MGH) and Brigham and Women's Hospital (BWH) in the United States has found that the Bacillus Calmette-Guerin (BCG) vaccine, which is commonly used to prevent tuberculosis, is associated with a reduced risk of Alzheimer's disease and related dementias. The study followed 6,467 individuals diagnosed with non-muscle-invasive bladder cancer for up to 15 years, comparing the outcomes of those who received BCG vaccine treatment (3,388 patients) with a control group (3,079 patients). The study discovered that the incidence of Alzheimer's disease and related dementias was 20% lower in the BCG vaccine group. The protective association was even greater among patients aged 70 years or older. Additionally, the study found that treatment with the BCG vaccine was associated with a 25% lower risk of death. The study now focuses on evaluating the potential benefits of BCG vaccination in older adults in Alzheimer's disease-related clinical trials. It is believed that if a causal link is established, it will be important to understand the mechanisms through which the BCG vaccine affects the immune system to provide these protective effects.

Ankylosing spondylitis was linked to a 40% higher PAD risk, especially among younger women, supporting early vascular assessment.

Ankylosing Spondylitis Linked to Higher Peripheral Artery Disease Risk

A nationwide South Korean cohort study found that people with ankylosing spondylitis (AS) had a 40% higher risk of peripheral artery disease (PAD) than matched controls. The risk was particularly elevated among women younger than 60 years, highlighting the importance of early vascular risk assessment and tailored prevention in AS.

Blinatumomab improved 4-year event-free survival versus chemotherapy in children with high-risk B-cell ALL.

Blinatumomab Improves Survival in Children With High-Risk B-ALL

A randomized trial in 709 children with newly diagnosed high-risk B-cell acute lymphoblastic leukemia found that replacing two cycles of conventional chemotherapy with blinatumomab increased estimated 4-year event-free survival to 83.0% versus 70.3%. Treatment-related infections and life-threatening adverse events were also less frequent, although neurotoxic events were more common with blinatumomab.

Five-year colonoscopy surveillance was noninferior to 3-year surveillance for colorectal cancer after high-risk adenoma removal.

5-Year Colonoscopy Interval Noninferior After High-Risk Adenoma Removal

An interim analysis of a 10,799-patient European trial found that starting surveillance colonoscopy 5 years after removal of high-risk adenomas was noninferior to starting at 3 years. At 5 years, colorectal cancer incidence was 0.77% with 5-year surveillance versus 0.82% with 3-year surveillance, with no substantial difference in cancer stage at diagnosis.

NEUROLOGY

Insomnia co-fluctuated with PTSD and depression over 10 years but did not predict later symptoms in military personnel.

Insomnia Linked to PTSD and Depression Symptoms in Military Personnel

A 10-year study of 846 Dutch military personnel found strong, persistent co-fluctuation between insomnia, PTSD and depression symptoms from before deployment through post-deployment follow-up. Insomnia did not predict later PTSD or depression, suggesting that sleep problems may reflect shared underlying vulnerabilities rather than independently driving these conditions.

UROLOGY

Endoscopic kidney-sparing surgery supported renal preservation in UTUC patients with a solitary kidney despite frequent recurrence.

Kidney-Sparing Surgery in UTUC With a Solitary Kidney

A multicentre study of 62 patients with upper tract urothelial carcinoma (UTUC) and a solitary kidney found that endoscopic kidney-sparing surgery enabled renal preservation despite frequent recurrences and repeated ureteroscopies. At 5 years, recurrence was 70%, progression 40%, and dialysis dependency 32%, supporting eKSS as an option when preserving the kidney is clinically imperative.

Tofacitinib improved PMR disease activity and reduced prednisone exposure when combined with steroids in a 6-month study.

Tofacitinib May Reduce Steroid Exposure in Polymyalgia Rheumatica

A retrospective study of 60 patients with polymyalgia rheumatica (PMR) found that tofacitinib-containing regimens improved disease activity, inflammatory markers, pain and morning stiffness over 6 months. Combining tofacitinib with prednisone was associated with significantly lower daily and cumulative prednisone exposure, with no serious adverse events reported during follow-up.

A Lebanese study identifies adult age as an independent risk factor for post-tonsillectomy hemorrhage.

Adult Age Increases Post-Tonsillectomy Hemorrhage Risk

A 10-year retrospective study of 945 patients at a Lebanese tertiary care center reported a 2.65% prevalence of post-tonsillectomy hemorrhage. Secondary bleeding accounted for 92% of cases and typically occurred around postoperative day 7. Adults had higher bleeding rates than children (7.4% vs. 1.9%), with adult age independently associated with increased risk (aOR 2.93).

ORTHOPAEDICS

Short-course systemic antibiotics were noninferior to longer therapy after orthopedic infection surgery with local antibiotic carriers.

Short-Course Antibiotics Effective After Orthopedic Infection Surgery

In a multicenter randomized trial of 500 patients undergoing orthopedic infection surgery with local antibiotic carriers, systemic antibiotics for ≤7 days were noninferior to ≥4 weeks for treatment failure at 12 months. Failure occurred in 11.1% versus 14.1%, respectively, while treatment-related symptoms by week 6 were less frequent with short-course therapy (17.2% vs 45.2%).

Root canal treatment reduced mechanical allodynia in adjacent and contralateral clinically sound teeth.

Root Canal Treatment Resolves Mechanical Allodynia in Sound Teeth

A study of 60 patients with symptomatic irreversible pulpitis found that root canal treatment significantly reduced mechanical allodynia in clinically sound adjacent and contralateral teeth. Improvements began within 24 hours, while near-complete resolution was observed by 3 months in almost all teeth, with one offending tooth showing persistent symptoms at 6 months.

Residual coronal tooth volume ≥41% was associated with improved 10-year survival after root canal retreatment.

Residual Coronal Volume Predicts Root Canal Retreatment Survival

A 10-year follow-up study of 156 posterior teeth found an estimated cumulative survival of 85.4% after root canal retreatment. Teeth retaining ≥41% residual coronal volume had lower extraction rates than those below this threshold (5.9% vs. 20.7%). Unfavourable 12-month CBCT findings were associated with a 4.5-fold higher extraction risk.
