Fournier's gangrene complicated by lower limb necrotising fasciitis and pelvic bone osteomyelitis: A case report with literature review.

Introduction And Importance: Fournier's gangrene is a urological emergency associated with high mortality and morbidity. Severe gangrene resulting in pelvic bone and lower limb involvement are extremely rare.

Case Presentation: We report a rare case of Fournier's gangrene that is complicated by necrotising fasciitis of the lower limb and osteomyelitis of the pelvic bone, in a patient with previous prostatic adenocarcinoma.

Graft retrieval incisions in minimally invasive donor nephrectomy: Systematic review and network meta-analysis.

Background: Various incisions are employed for graft extraction during minimally invasive donor nephrectomy, but an overarching synthesis of associated short-term donor outcomes is lacking.

Methods: An electronic literature search was conducted on PubMed, EMBASE and Scopus for studies comparing ≥2 graft extraction incisions in laparoscopic or robotic donor nephrectomy with ≥10 patients per arm. Eligible study designs included randomized trials, case-control, and cohort studies.

Quantum Signatures of Black Hole Mass Superpositions.

We present a new operational framework for studying "superpositions of spacetimes," which are of fundamental interest in the development of a theory of quantum gravity. Our approach capitalizes on nonlocal correlations in curved spacetime quantum field theory, allowing us to formulate a metric for spacetime superpositions as well as characterizing the coupling of particle detectors to a quantum field. We apply our approach to analyze the dynamics of a detector (using the Unruh-deWitt model) in a spacetime generated by a Banados-Teitelboim-Zanelli black hole in a superposition of masses.

Relativistic Bohmian trajectories of photons via weak measurements.

Bohmian mechanics is a nonlocal hidden-variable interpretation of quantum theory which predicts that particles follow deterministic trajectories in spacetime. Historically, the study of Bohmian trajectories has mainly been restricted to nonrelativistic regimes due to the widely held belief that the theory is incompatible with special relativity. Here, we present an approach for constructing the relativistic Bohmian-type velocity field of single particles.
