Objectives: To develop: (1) two validated risk prediction models for coronavirus disease-2019 (COVID-19) positivity using readily available parameters in a general hospital setting; (2) nomograms and probabilities to allow clinical utilisation.
Methods: Patients with and without COVID-19 were included from 4 Hong Kong hospitals. The database was randomly split into 2:1: for model development database (n = 895) and validation database (n = 435).
Article Synopsis
- A young, fit man suffered from severe heat stroke after running a 10 km race, despite being in good physical shape.
- He had undergone a surgical procedure called bilateral thoracic sympathectomy to reduce sweating, which left him with limited sweating in his upper body and limbs.
- This case highlights the importance of understanding how reduced sweating and altered body responses can increase the risk of heat-related illnesses in individuals who have had this type of surgery.
Article Synopsis
- Pulmonary alveolar proteinosis (PAP) is a rare lung disorder where abnormal material builds up in the alveoli, hindering gas exchange.
- A 29-year-old woman had an extreme case of PAP and underwent aggressive bilateral whole lung lavage (WLL) with extracorporeal membrane oxygenation (ECMO) support.
- After being critically ill for 12 days and relying on a ventilator, she showed rapid improvement in lung function following the procedure, demonstrating that WLL with ECMO can be both safe and effective in severe PAP cases.
