PURPOSE: Short life expectancy influences decision-making when treating very old patients with acute ischemic stroke (AIS). We investigated mortality and survival duration in very old AIS patients (> or =80 years) who received hospital care. PATIENTS AND METHODS: Mortality data were obtained from medical records, structured telephone inquiries, death certificates from the Korean National Statistical Office, and social security data 5+/-1.9 years after stroke onset. Age, gender, vascular risk factors, and functional outcomes from modified Rankin scales (MRS) at discharge were analyzed as predictors of mortality. RESULTS: Among 134 patients, 92 (68.7%) died. On Kaplan- Meier analysis, duration of survival of patients aged 80-84 years was longer than those aged 85-89 or 90-94 (24+/-6.4, 8+/-7.3, 7+/-2.0 months, respectively, p=0.002). Duration of survival of patients discharged in a state of MRS 0-1 was longer than the remaining groups at 47+/-4.8 months (p<0.001). In Cox proportional hazard analysis, age and MRS at discharge were independent predictors of mortality. CONCLUSION: Long-term outcomes of very old patients with AIS are not uniformly grave, therefore predictors of mortality and estimated duration of survival should be considered during decision- making for treatment.

INTRODUCTIONThis study aimed to determine the incidence of hypoxic-ischaemic encephalopathy (HIE) and predictors of HIE mortality in Malaysian neonatal intensive care units (NICUs).

METHODSThis was a retrospective study of data from 37 NICUs in the Malaysian National Neonatal Registry in 2012. All newborns with gestational age ≥ 36 weeks, without major congenital malformations and fulfilling the criteria of HIE were included.

RESULTSThere were 285,454 live births in these hospitals. HIE was reported in 919 newborns and 768 of them were inborn, with a HIE incidence of 2.59 per 1,000 live births/hospital (95% confidence interval [CI] 2.03, 3.14). A total of 144 (15.7%) affected newborns died. Logistic regression analysis showed that the significant predictors of death were: chest compression at birth (adjusted odds ratio [OR] 2.27, 95% CI 1.27, 4.05; p = 0.003), being outborn (adjusted OR 2.65, 95% CI 1.36, 5.13; p = 0.004), meconium aspiration syndrome (MAS) (adjusted OR 2.16, 95% CI 1.05, 4.47; p = 0.038), persistent pulmonary hypertension of the newborn (PPHN) (adjusted OR 4.39, 95% CI 1.85, 10.43; p = 0.001), sepsis (adjusted OR 4.46, 95% CI 1.38, 14.40; p = 0.013), pneumothorax (adjusted OR 4.77, 95% CI 1.76, 12.95; p = 0.002) and severe HIE (adjusted OR 42.41, 95% CI 18.55, 96.96; p < 0.0001).

CONCLUSIONThe incidence of HIE in Malaysian NICUs was similar to that reported in developed countries. Affected newborns with severe grade of HIE, chest compression at birth, MAS, PPHN, sepsis or pneumothorax, and those who were outborn were more likely to die before discharge.
