A new study reveals that frailty-associated gut dysbiosis significantly elevates the risk of gastrointestinal complications following intracorporeal urinary diversion for bladder cancer. Despite short-term antibiotic prophylaxis, residual intra-abdominal bacteria and fungi—particularly Enterococcus and Enterobacter—were strongly associated with postoperative ileus and infections. The findings underscore frailty as a key determinant of surgical outcomes and point toward microbiota-based management strategies to improve recovery and reduce complications.

Increased chromosomal instability impairs oocyte quality, contributing to female reproductive aging. The telomeric DNA damage response (DDR) is essential for genomic stability. Although telomeric DDR has been extensively studied in somatic cells, its role in oocyte aging remains unclear.

A new study identifies the Levant Basin in the southeastern Mediterranean as one of the world's most polluted deep-sea regions, with exceptionally high concentrations of plastic bags and packaging on the seafloor. The research uncovers how lightweight plastic, once thought to float indefinitely, sinks through a combination of sediment, tar, and shell adhesion—solving a long-standing mystery of deep-sea plastic accumulation.

The project aims to study the mental health of adolescents aged 14 to 17 living in Spain and to analyse which support networks are important at this stage. To do so, both qualitative and quantitative methodologies were combined, yielding several samples: a representative sample of 806 adolescents nationwide and an additional sample of 228 LGTBI+ adolescents for the survey and 44 LGTBQI+ participants in discussion groups.

The results show that 11.2% of adolescents in the overall sample report feeling very or quite unhappy, and 38.8% indicate that they have experienced loneliness regularly in the past year. Regarding depression, 14% would be experiencing severe episodes, and 6.6% would be in very severe episodes.

Additionally, the study finds that 15.7% of respondents report having attempted suicide, 19.8% have considered it, and 29.3% have engaged in self-harming behaviours in the past year, of which 10.5% report thinking about it frequently.
