A new review delves into the intricate relationship between Sjogren's syndrome (SS) and the diverse oral microbiome. While there's no distinct microbiome pattern in SS due to its varied manifestations, salivary secretion rates, and risk factors, Gram‐positive species are more abundant in the oral niches of affected individuals. These findings suggest the resilience of such bacteria in the dry oral environment. Reduced salivary flow isn't the sole cause of microbial imbalance but plays a role in host-associated risk factors. The study highlights the need for further research to decipher the microbiome's role in SS's development.

Prostate MRI may improve risk stratification of Grade Group 1 prostate cancer beyond traditional NCCN risk groups.

MRI Refines Risk Stratification in Grade Group 1 Prostate Cancer

A study of Grade Group 1 prostate cancer found that NCCN risk groups predicted adverse pathology and recurrence before the MRI era, but showed limited prognostic value among patients evaluated with preoperative MRI. In the MRI era, age, PI-RADS findings and biopsy core positivity were associated with adverse pathology, supporting MRI and biopsy features for contemporary risk assessment.

BRCA alterations were more common in younger patients; BRCA2 homozygous deletion was linked to longer survival with olaparib.

BRCA Alterations and Olaparib Outcomes in Advanced Prostate Cancer

A Japanese genomic profiling study of 2,815 patients with advanced, therapy-resistant prostate cancer found deleterious BRCA alterations in 15.2% of patients, with higher rates among younger patients and those with a family history of breast or ovarian cancer. Among BRCA2-altered patients treated with olaparib, homozygous deletion was associated with longer overall survival than truncating variants.

Thyroidectomy after thermal ablation is feasible but may be technically more complex, with limited evidence on long-term risks.

Thyroidectomy After Thermal Ablation: Surgical Risks and Outcomes

A systematic review of nine retrospective studies involving 150 patients found that thyroidectomy after radiofrequency, laser or microwave ablation was feasible but could be technically more difficult. Prior ablation was associated with longer operative times and more severe adhesions, while permanent nerve or parathyroid complications were rarely reported. Evidence remains limited and heterogeneous.

Study finds cerebral blood-flow differences mainly distinguish sFGR types, while myocardial changes remain a research phenotype.

Cerebral and Myocardial Changes in Twin sFGR | Study

A cohort study of 82 monochorionic diamniotic twin pregnancies with selective fetal growth restriction found that Gratacós type was reflected mainly by differences in cerebral blood flow and redistribution. Myocardial changes were also observed, including in larger co-twins, but did not significantly distinguish types after correction, suggesting a potential research phenotype.

UK Biobank study finds EOSS and DMO classify obesity severity differently, particularly in early or subclinical disease.

EOSS vs DMO: Comparing Obesity Classification Frameworks

A UK Biobank analysis of about 411,000 participants compared the Edmonton Obesity Staging System with the Lancet Commission Diagnostic Model for Obesity. Both identified obesity in roughly one-quarter of participants, but differed mainly in early-stage disease. The DMO captured broader mild or subclinical organ dysfunction, while EOSS emphasized more advanced obesity-related disease.

Study finds ED in 93.8% of men with atherosclerotic disease, supporting its role as a marker of systemic vascular pathology.

Erectile Dysfunction Prevalence in Patients With Atherosclerosis

A single-centre study of 162 men with documented atherosclerotic disease found erectile dysfunction in 93.8%, with severe ED affecting 62.3%. Older age, particularly over 75 years, was associated with ED, while age, diabetes and longer ED duration were linked to greater severity. The findings support ED assessment as part of cardiovascular risk evaluation.
