Hypoxic-ischemic brain injury is the main cause of death and disability of comatose patients after cardiac arrest. Early and reliable prognostication is challenging. Common prognostic tools include clinical neurological examination and electrophysiological measures. Brain imaging is well established for diagnosis of focal cerebral ischemia but has so far not found worldwide application in this patient group. ⋯ CT derived grey-white matter ratio and MRI based measures of diffusivity and connectivity hold promise to improve outcome prediction after cardiac arrest. Prospective validation studies in a multivariable approach are needed to determine the additional value for the individual patient.

Perinatal and neonatal deaths account for an increasing proportion of deaths under 5 years old. We present essential elements to reduce perinatal mortality, barriers to establishing these elements, and the role of developing emergency care systems. Essential elements for prompt perinatal and postnatal care are categorised based on care-seeking behaviours, access to a primary care facility and for the severely ill, access to advanced neonatal care. The role of emergency care systems is key to overcoming obstacles currently faced in countries with high perinatal and neonatal mortality rates.

Exercise-related resuscitated out-of-hospital cardiac arrest due to presumed myocardial ischemia: Result from coronary angiography and intravascular ultrasound.
Possible causes of exercise-related out-of-hospital cardiac arrest (OHCA) in people with coronary artery disease (CAD) include atherosclerotic plaque rupture (PR) and intra-coronary thrombosis, exercise-induced myocardial ischaemia and other triggers. We investigated whether there are differences in the incidence of PR and/or intra-coronary thrombus and in clinical outcome between 'exercise-related' and 'non-exercise-related' OHCA. ⋯ The incidence of PR and/or thrombosis was lower in the group taking higher levels of exercise, than in the group taking less or no exercise. "Exercise-related" OHCA with CAD has better clinical outcomes than "non-exercise-related" with a greater proportion of witnessed arrests and early return of spontaneous circulation.
