Observational Study
Pulseless electrical activity is associated with improved survival in out-of-hospital cardiac arrest with initial non-shockable rhythm.
To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm. ⋯ Between 1990 and 2016, the proportion of PEA as the first recorded rhythm doubled with a five-fold increase in 30-day survival, while survival among patients with asystole remained at low levels. PEA and asystole should be considered separate entities in clinical decision-making and be reported separately in observational studies and clinical trials.

Patients suffering out-of-hospital cardiac arrest (OHCA) have a poor prognosis but survival among subgroups differs greatly. Previous studies have shown conflicting results on whether patient comorbidity affects outcome. The aim of this national study was to investigate the effect of comorbidity on outcome after OHCA in Sweden. ⋯ This large national study showed that increasing comorbidity decreased the chance of survival to 30 days in OHCA. This association remained after covariate adjustment.

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.
