Microfluidic sperm selection mimics natural reproductive conditions and may improve sperm quality for IVF and ICSI.

Microfluidic Sperm Selection Advances in Assisted Reproduction

A review highlights advances in sperm selection for assisted reproductive technologies, emphasizing microfluidic systems that mimic conditions of the female reproductive tract. Unlike conventional swim-up and density-gradient methods, these devices can select sperm based on motility, thermotaxis, chemotaxis, and rheotaxis. Larger multicenter studies are needed to confirm their clinical benefits.

NEUROLOGY

Women with OSA showed greater functional impairment despite milder respiratory measures, highlighting the role of comorbidities.

Women With OSA Have Greater Functional Impairment Despite Milder Disease

A study of 518 untreated patients with obstructive sleep apnoea found that women experienced greater mood symptoms and daytime functional impairment despite lower apnoea-hypopnoea index and hypoxic burden than men. Respiratory measures did not consistently explain these differences, while comorbid mood disorders, insomnia, and chronic pain had a stronger influence on functional outcomes.

ENDO-DIABETOLOGY

Integrating mental health and behavioral assessment could improve personalized obesity treatment and long-term outcomes.

Integrating Mental Health Into Personalized Obesity Care

A new Perspective calls for integrating mental health into obesity management, highlighting the high prevalence of psychiatric disorders and their impact on treatment resistance, adherence, and outcomes. The authors advocate behavioral phenotyping alongside therapies such as GLP-1 receptor agonists, with multidisciplinary care, psychological assessment, stigma reduction, and personalized nutrition counseling.

DENTISTRY

Contemporary adhesive strategies showed no significant differences in 12-month outcomes for posterior composite restorations.

Adhesive Strategies Show Similar Outcomes in Posterior Restorations

A systematic review and network meta-analysis of randomized trials found no significant differences among contemporary adhesive strategies used for direct posterior composite restorations in permanent teeth. At 12 months, marginal adaptation and retention loss were similar across approaches. Although etch-and-rinse and universal adhesives ranked higher, evidence was uncertain due mainly to imprecision.

CRT-D showed no clear survival advantage over CRT-P in nonischemic cardiomyopathy but had more device-related complications.

CRT-D Shows No Clear Survival Benefit Over CRT-P in NICM

A nationwide Veterans Affairs cohort study of 3,965 patients with nonischemic cardiomyopathy found no significant difference in mortality between CRT-D and CRT-P over a median 5.2-year follow-up. CRT-D was also associated with higher rates of generator replacement and device-related infections, highlighting uncertainty about the added value of defibrillator therapy in this population.
