CARDIOLOGY

A study explores the relationship between cardiac allograft vasculopathy (CAV), reduced myocardial blood flow (RMBF), and elevated donor-derived cell-free DNA (dd-cfDNA) levels in heart transplant recipients.

Association Between Cardiac Allograft Vasculopathy, Reduced Myocardial Blood Flow, and Donor-Derived Cell-Free DNA

Cardiac allograft vasculopathy (CAV) compromises myocardial blood flow (MBF) and increases cardiovascular risks in heart transplant (HT) recipients. This retrospective study evaluated the association of CAV and reduced MBF (RMBF) with donor-derived cell-free DNA (dd-cfDNA) levels in 256 HT recipients. The results revealed no significant differences in dd-cfDNA levels between patients with and without angiographic CAV. However, dd-cfDNA levels were markedly higher in patients with RMBF (≤2 MBF reserve) compared to those with normal MBF. These findings suggest that while angiographic CAV may not correlate with dd-cfDNA elevation, RMBF is significantly associated with increased dd-cfDNA, highlighting its potential as a biomarker for impaired MBF.

Study links genital responses during sexual trauma recall with PTSD severity and significant emotional and daily-life impact.

Genital Responses to Sexual Trauma Memories Linked to PTSD Severity

A study of 1,057 patients with PTSD and a history of sexual abuse found that 34.4% reported genital responses during sexual abuse memory recall. Most experienced shame, disgust, or self-hatred, while 38.2% reported a strong impact on daily life. Disgust and self-hatred were associated with greater PTSD severity, supporting systematic clinical assessment of these responses.

RHEUMATOLOGY

Severe microvascular damage in systemic sclerosis was linked to bilateral carotid plaques, while age and SBP remained key predictors.

Systemic Sclerosis Microvascular Damage Linked to Carotid Plaques

A cross-sectional study of 165 patients with systemic sclerosis found carotid plaques in 46.7%, including bilateral plaques in 20.6%. Although overall nailfold videocapillaroscopy abnormalities were not associated with carotid atherosclerosis, late scleroderma patterns, avascular areas, and reduced capillary density were linked to bilateral plaques. Age and systolic BP remained stronger predictors of carotid disease.

Study finds mild liver enzyme elevations common with allopurinol, with alcohol increasing risk and dose escalation remaining safe.

Allopurinol and Liver Enzyme Elevation in Gout Patients

A prospective study of 150 gout patients found that 20% developed elevated AST/ALT after starting allopurinol, with 86.7% of cases being mild and none severe. Alcohol use independently increased the risk, while statin use appeared protective. Liver enzyme elevation was not linked to higher allopurinol doses, supporting dose escalation despite mild-to-moderate elevations.

The findings highlight the complexity of OAB treatment selection beyond cost and comorbidities and support further research into prescribing decisions.

DERMATOLOGY

A 2026 review finds insufficient evidence to support omega fatty acids as a standalone treatment for alopecia.

Omega Fatty Acids for Hair Loss: What Does the Evidence Show?

Could omega fatty acids support hair growth? A 2026 scoping review found preclinical evidence suggesting omega-3, omega-6, and omega-9 fatty acids may influence follicle growth, inflammation, and hair loss pathways. Some clinical studies reported improved density and reduced shedding, but evidence remains inconsistent, and current data do not support omega fatty acids as a standalone treatment for alopecia.

DENTISTRY

Review reveals four factors patients value most in quality dental care, including competence, communication, trust, and continuity.

What Defines Quality Dental Care? Insights From Patients

A systematic review of 36 qualitative studies reveals how patients define quality dental care beyond clinical expertise. Four key factors emerged: confidence in organizational systems, perceived clinical competence, respectful and empathetic communication with shared decision-making, and continuity of care. The findings highlight how relational and emotional experiences can shape trust, expectations, and long-term engagement with dental services.

Oral microbiome models using saliva and supragingival plaque show strong potential for noninvasive periodontitis detection.

Oral Microbiome Shows Promise for Noninvasive Periodontitis Diagnosis

Can a simple saliva sample help detect periodontitis? An analysis of 2,303 samples found that saliva and supragingival plaque provided stronger diagnostic performance than subgingival plaque. Compact microbial signatures combined with generalized additive models achieved AUCs of 0.928 and 0.903, respectively, highlighting the potential for scalable, noninvasive microbiome-based diagnostics in precision periodontics.

Review explores how pVHL aggregation may promote tumor dormancy and drug resistance and identifies potential therapeutic targets.

Protein aggregation, pVHL, von Hippel-Lindau, tumor dormancy, cancer drug resistance, amyloid aggregation, chemical chaperones, oncology

A review highlights protein aggregation as a dynamic, reversible process in cancer, focusing on von Hippel-Lindau tumor suppressor protein (pVHL). Mutations, stress, and chaperone dysfunction may promote pVHL aggregation, supporting tumor cell survival and dormancy. Targeting aggregation with chemical chaperones or amyloid inhibitors could potentially restore tumor-suppressor activity and overcome drug resistance

NEUROLOGY

Fetal myocardial performance index at 20–24 weeks did not predict subsequent fetal growth restriction in low-risk pregnancies.

Fetal MPI Does Not Predict Fetal Growth Restriction in Low-Risk Pregnancies

A prospective cohort study of 303 low-risk singleton pregnancies found that fetal myocardial performance index (MPI) measured at 20–24 weeks of gestation did not significantly differ between fetuses who later developed fetal growth restriction (FGR) and controls. The findings suggest that early second-trimester MPI may not be a useful predictor of subsequent FGR in low-risk pregnancies.
