Nuclear factor erythroid-2 related factor 2 inhibits human disc nucleus pulpous cells apoptosis induced by excessive hydrogen peroxide.
OBJECTIVE Nuclear factor erythroid-2 related factor 2 (Nrf2)/ antioxidant response element (ARE) is a novel defensive pathway involved in the oxidative and chemical stress of cells. The aim of the study was to explore the role of Nrf2 on the apoptosis of human disc nucleus pulpous cells induced by hydrogen peroxide (H2O2). METHODS The degeneration model of human intervertebral disc nucleus pulpous cells was established. ⋯ In Western blotting, Nrf2 content in the experimental group was higher than that in the control group. CONCLUSION Nrf2 exists in the nucleus pulpous cells of human intervertebral discs, which is related to the degeneration of the intervertebral disc. It has negative feedback regulation and can prevent the degeneration of the intervertebral disc by inhibiting the apoptosis of nucleus pulpous cells of human intervertebral discs caused by excessive ROS, which provides a new intervention strategy for the prevention and treatment of the degeneration of intervertebral discs.

Role of a Neonatal Intensive Care Unit during the COVID-19 Pandemia: recommendations from the neonatology discipline.
On 11th March 2020, the World Health Organization (WHO) declared the COVID-19 a pandemic. The Obstetrics and Neonatology disciplines needed to be revised to suit the institutional need to expand intensive care beds to care for confirmed or suspected patients with COVID-19 in the state of São Paulo, following the recommendations of the Institutional Crisis Committee. ⋯ Some special considerations about breastfeeding and rooming-in were needed. The third action was the drafting of a protocol to admit infants from other hospitals with confirmed COVID-19 as the unit never admitted outpatients before.

Case ReportsEosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome).
Churg-Strauss syndrome, Eosinophilic granulomatosis with polyangiitis (EGPA), is a systemic vasculitis that affects small- to medium-sized vessels. It is rare and part of the Anti-neutrophil cytoplasm antibody-associated vasculitis (ANCA) group. We present a 37-year-old man, with a previous history of asthma, that was sent to the ED due to 2 weeks of productive cough, occasional dyspnea on exertion, fever (one week), asthenia, and anorexia. ⋯ After the biopsy, he received three 1g methylprednisolone pulses and was started on Cyclophosphamide. He remained asymptomatic and renal function was restored. This case highlights the importance of integrating all findings in one clinical scenario to prevent a more complex disease diagnosis, with a specific treatment, from being missed.
