Efficacy of energy‐based devices on episiotomy pain and healing: A systematic review and meta‐analysis

International Journal of Gynecology &Obstetrics, Volume 173, Issue 3, Page 1284-1294, June 2026.
Abstract Background Episiotomy is a common obstetric procedure often associated with significant postpartum pain and delayed wound healing. Conventional treatments provide limited relief and might not be suitable for all women. Energy‐based therapies, including infrared irradiation and low‐level laser therapy (LLLT), a non‐thermal photo biomodulation ...

Whole Genome Sequence Analysis of Weight Loss in 16 972 Participants With COPD Reveals Novel Risk Loci in DRAIC and RFX3

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 3, June 2026.
ABSTRACT Background Chronic obstructive pulmonary disease (COPD) is associated with musculoskeletal comorbidities, including cachexia. Weight loss (WL) is the major criterion for cachexia and increases risk for mortality in COPD. Risk factors for WL in COPD are incompletely understood.

Towards Clinical Translation of Intravoxel Incoherent Motion MRI: Acquisition and Analysis Consensus Recommendations

Journal of Magnetic Resonance Imaging, Volume 63, Issue 6, Page 1782-1801, June 2026.
ABSTRACT Intravoxel incoherent motion (IVIM) MRI allows for simultaneous assessment of tissue microcirculation (perfusion) and diffusion of water. In single‐center studies, IVIM has shown great potential for diagnosis, treatment outcome prediction, and treatment monitoring for many different diseases and organs.
