FAERS analysis identifies potential drug-related ectopic pregnancy safety signals, warranting further clinical investigation.

Drug-Related Ectopic Pregnancy Safety Signals: FAERS Study

A pharmacovigilance study analyzing FDA adverse event reports from 2004 to 2024 identified 4,924 ectopic pregnancy reports. Levonorgestrel, etonogestrel, and clomifene showed the strongest disproportionate reporting signals, while 16 drugs emerged as potential novel safety signals. These findings may guide further drug-safety research but do not establish causation or confirm increased ectopic pregnancy risk.

Trial finds ex utero cord blood collection comparable to standard collection in weight, cellular composition, and contamination.

Ex Utero vs In Utero Umbilical Cord Blood Collection

A randomized clinical trial involving 101 umbilical cord blood collections found that ex utero collection, performed after placental delivery, was non-inferior to standard in utero collection in terms of blood unit weight. Cellular composition and bacterial contamination rates were also comparable, supporting ex utero collection as a clinically viable alternative that may improve maternal comfort during childbirth and facilitate cord blood donation.

NEUROLOGY

Study links prior concussion to persistent choice reaction-time slowing in collegiate athletes, despite adjusted cognitive scores.

Concussion History and Reaction Time in Collegiate Athletes

A study of 547 NCAA Division I athletes found that those with a history of concussion had significantly slower choice reaction times than matched controls, even after adjusting for memory, concentration, and cognitive performance. No significant differences were observed in simple reaction time, Stroop reaction time, or shifting-attention reaction time, suggesting that choice reaction time may help detect subtle, persistent neurocognitive deficits after concussion.

Study highlights sexual health disparities among transgender individuals, emphasizing inclusive care and policies addressing stigma.

Sexual Health and Vulnerability Among Transgender Individuals

A cross-sectional study of 74 transgender individuals in São Paulo, Brazil, found differences in relationship status, sexual partnerships, and sex work between trans women and trans men. Trans women were more frequently single (76% vs 44.9%) and more likely to report sex work (21.7% vs 6.3%). The findings highlight the need for inclusive sexual health services and policies addressing stigma and structural inequalities.

Meta-analysis links tumor budding to poorer survival in endometrial cancer, highlighting the need for further validation.

Tumor Budding as a Prognostic Marker in Endometrial Cancer

A systematic review and meta-analysis of 10 studies involving 1,307 patients found that tumor budding was associated with poorer progression-free survival (HR 2.44) and overall survival (HR 1.89) in endometrial cancer. However, evidence linking tumor budding to lymph node metastasis was inconsistent. Standardized assessment and validation in larger, molecularly stratified studies are needed to establish its prognostic value.

Meta-analysis finds virtual reality reduces pain and anxiety during and after gynaecological procedures, with few minor adverse events.

Virtual Reality for Pain and Anxiety in Gynaecological Procedures

A systematic review and meta-analysis of 25 randomized controlled trials involving 2,438 women found that immersive virtual reality (IVR) significantly reduced pain and anxiety during and after gynaecological procedures. Post-procedural pain and anxiety showed greater reductions, while reported adverse events were minor and infrequent. IVR may offer a safe, non-pharmacological adjunct to improve patient comfort and procedural experience.
