Apparent Diffusion Coefficient of the Optic Nerve Head in Idiopathic Intracranial Hypertension.

Idiopathic Intracranial Hypertension (IIH) is a condition in which patients have elevated intracranial pressure which does not have an apparent cause. To diagnose IIH, evaluation excluding other causes of elevated pressure must be performed. This typically includes magnetic resonance imaging (MRI) of the brain and venous sinuses.

Transcripts of repetitive DNA elements signal to block phagocytosis of hematopoietic stem cells.

Macrophages maintain hematopoietic stem cell (HSC) quality by assessing cell surface Calreticulin (Calr), an "eat-me" signal induced by reactive oxygen species (ROS). Using zebrafish genetics, we identified Beta-2-microglobulin (B2m) as a crucial "don't eat-me" signal on blood stem cells. A chemical screen revealed inducers of surface Calr that promoted HSC proliferation without triggering ROS or macrophage clearance.

Sterile kidney tissue injury induces neutrophil swarming in lung alveolar capillaries.

Sterile tissue injury, such as by acute kidney injury, is common in the clinic and frequently associated with respiratory compromise and hypoxemia. We previously described signaling components released by the injured kidney that drive a remote inflammatory response in the lung. How this caused the resultant hypoxemia remained unclear.

Assessment of severity and feto-maternal outcomes among COVID-19 infected pregnant females hospitalized at tertiary care center in western Nepal.

Objective: There is a paucity of data assessing the severity of coronavirus disease 2019 (COVID-19) infection and feto-maternal outcomes in pregnant women in Nepal, especially during the third wave of the pandemic with the Delta variant. This study aimed to severity as well as maternal-fetal outcomes among pregnant women with COVID-19 infection.

Methods: In this cross-sectional study carried out amongst COVID-19 positive pregnant women visiting our institution for 6 months from January through June 2022, data surrounding COVID-19 severity and fetal outcomes were collected in a structured questionnaire.
