What Causes Mediastinal Masses?
Discussion
The mediastinum resides in the chest and is the space bounded by the thoracic inlet cephalically, diaphragm caudally, sternum anteriorly and transverse process of the spine posteriorly, and mediastinal pleura and lungs laterally. It is divided into various compartments:
Superior mediastinum
Bounded by the thoracic inlet cephalically and a horizontal plane passing from the manubriosternal joint to the junction of T4/T5 vertebrae horizontally.
Structures include: esophagus, trachea, parts of great vessels and first branches, great veins and initial branches, thymus, vagus, phrenic and other nerves, thoracic duct...

Janssen Reports Positive Topline Phase 2 Results for Nipocalimab in Pregnant Individuals at High Risk for Severe Hemolytic Disease of the Fetus and Newborn (HDFN)
SPRING HOUSE, PENNSYLVANIA, February 6, 2023 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced positive topline results from the proof-of-concept Phase 2 open-label UNITY clinical trial for the treatment of pregnant adults at high risk for severe hemolytic disease of the fetus and newborn (HDFN). HDFN is a serious and rare condition which can cause life-threatening anemia in the fetus. It occurs when the blood types of a pregnant individual and their fetus are incompatible.1 The trial met the primary endpoint, with the majority of pregnant patients who received nipocalimab achieving a live b...

Renin as a Marker of Tissue Perfusion, Septic Shock and Mortality in Septic Patients: A Prospective Observational Study
Objectives: To characterize renin in critically ill patients. Renin is fundamental to circulatory homeostasis and could be a useful marker of tissue-perfusion. However, diurnal variation, continuous renal replacement therapy and drug-interference could confound its use in critical care practice.
Design: Prospective observational study.
Setting: Single-center, mixed medical-surgical ICU in Europe.
Patients: Patients over 18 years old with a baseline estimated glomerular filtration rate greater than 30 mL/min/1.73 m and anticipated ICU stay greater than 24 hours. Informed consent was obtained from the patient or next-of-k...
