Resuscitative endovascular balloon occlusion of the aorta for trauma patients with uncontrolled hemorrhage: a retrospective target trial emulation (the AT-REBOA target trial).

Background: Noncompressible truncal hemorrhage is a major contributor to preventable deaths in trauma patients and, despite advances in emergency care, still poses a big challenge.

Objectives: This study aimed to assess the clinical efficacy of trauma resuscitation care incorporating Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) compared to standard care for managing uncontrolled torso or lower body hemorrhage.

Methods: This study utilized a target trial design with a matched case-control methodology, emulating randomized 1 : 1 allocation for patients receiving trauma resuscitation care with or without the use of REBOA.

Compound-dependent fetal toxicity after in utero exposure to chemotherapy in a pregnant mouse model.

Although chemotherapy is integrated in the treatment of second-trimester pregnant cancer patients, its potential cyto- and genotoxicity to fetal tissue remains unknown. To investigate any causal relation between in utero chemotherapy exposure and fetal toxicity, late-gestation pregnant BL6 mice were exposed to vehicle, or one of six chemotherapeutic compounds, used to treat pregnant cases: cyclophosphamide, carboplatin, cisplatin (alkylating agents), epirubicin, doxorubicin (anthracyclines) or paclitaxel (taxane). fetuses were euthanized at gestational day 18.

Efficiency of multivariate tests in trials in progressive supranuclear palsy.

Measuring disease progression in clinical trials for testing novel treatments for multifaceted diseases as progressive supranuclear palsy (PSP), remains challenging. In this study we assess a range of statistical approaches to compare outcomes as measured by the items of the progressive supranuclear palsy rating scale (PSPRS). We consider several statistical approaches, including sum scores, a modified PSPRS rating scale that had been recommended by FDA in a pre-IND meeting, multivariate tests, and analysis approaches based on multiple comparisons of the individual items.
