Later lines of systemic therapy in patients with metastatic colorectal cancer: real-world data from a setting with barriers to access cancer therapies.

Background: Regorafenib and trifluridine/tipiracil (TFD/TPI) are oral systemic therapies with survival benefit in chemorefractory metastatic colorectal cancer (mCRC) patients, but they are not widely available worldwide. We aimed to evaluate the treatment patterns and outcomes of patients with limited access to these drugs.

Methods: Retrospective study involving 510 patients with mCRC who were treated at five different centers in Brazil, from January 2011 to December 2019.

Angiogenic factors versus fetomaternal Doppler for fetal growth restriction at term: an open-label, randomized controlled trial.

Small fetuses, with estimated fetal weight (EFW) below the tenth percentile, are classified as fetal growth restriction (FGR) or small for gestational age (SGA) based on prenatal ultrasound. FGR fetuses have a greater risk of stillbirth and perinatal complications and may benefit from serial ultrasound scans to guide early delivery. Abnormal serum angiogenic factors, such as the soluble fms-like tyrosine kinase-1 (sFlt-1):placental growth factor (PlGF) ratio, have shown potential to more accurately distinguish FGR from SGA, with fewer false positives.

Continuous Risk Assessment of Late and Term Preeclampsia Throughout Pregnancy: A Retrospective Cohort Study.

: To evaluate the diagnostic accuracy of widely available biomarkers longitudinally measured throughout pregnancy to predict all and term (delivery at ≥37 weeks) preeclampsia (PE). : This is a longitudinal retrospective study performed at Hospital Universitario de Torrejón (Madrid, Spain) and Shterev Hospital (Sofia, Bulgaria) between August 2017 and December 2022. All pregnant women with singleton pregnancies and non-malformed live fetuses attending their routine ultrasound examination and first-trimester screening for preterm PE at 11 + 0 to 13 + 6 weeks' gestation at the participating centers were invited to participate in a larger study for the prediction of pregnancy complications.

"Thoracic anesthesia in patients with airborne disease".

Health care workers are at risk of infection from aerosolization of respiratory secretions, droplet and contact spread. This has gained great importance after the COVID19 pandemic. Intra-operative aerosol-generating procedures are arguably unavoidable in the routine provision of thoracic anesthesia.

MCL-1 regulates cellular transitions during oligodendrocyte development.

Oligodendrocytes are the myelinating cells of the central nervous system. Regulation of the early stages of oligodendrocyte development is critical to the function of the cell. Specifically, myelin sheath formation is an energetically demanding event that requires precision, as alterations may lead to dysmyelination.
