Late Hospital Arrival for Thrombolysis after Stroke in Southern Portugal: Who Is at Risk?

BACKGROUND: Delayed hospital arrival remains the main reason for the low rates of thrombolysis in eligible acute ischemic stroke (AIS) patients. The role of socioeconomic and clinical factors for the prehospital delay of AIS remains poor and has never been studied in Portugal. OBJECTIVES: Describe the socioeconomic and clinical factors leading to delayed hospital admission of AIS patients eligible to thrombolysis. METHODS: A case-control study with a consecutive thrombolyzed AIS patients from 2010 to 2015. Controls were patients who did not receive thrombolysis because of late hospital arrival. Logistic regression with stepwise forward regression analysis was used to identify independent predictors of delayed admission to receive thrombolysis with intravenous tissue-type plasminogen activator (rtPA). RESULTS: Of the 1247 patients admitted with AIS, 76 (6%) arrived on-time and received intravenous rtPA. Controls were 65.8% (146/222) of the total number of patients included in the study. Overall, the mean age was 73 years (±11, 61), a minority were below 60 years, and 43.7% were women. Being beneficiary of social insertion income (odds ratio [OR]: .286; .124-.662, P = .003), not having any telephone contact (OR: .145; .039-.536, .004) or having exclusive landline (.055; .014-.210, <.001) and posterior circulation stroke (OR: .266; .087-.811, P = .020) decreased the likelihood of hospital arrive on-time rtPA. The use of prehospital ambulance services increased (OR: 6.478; 2.751-15.254, P < .001) the odds of ER on-time arrival for thrombolysis. CONCLUSIONS: Poverty, lack of stroke awareness, or difficulties in requesting immediate medical help are the main factors implicated in late-hospital admission for thrombolysis in AIS. Stroke awareness campaigns, promotion of activation of national emergency number and stroke code can increase the rate of thrombolysis.

A reversible case of rapidly progressive dementia-Hypercalcemia due to hyperparathyroidism.

With an increasingly aging population, it is of extreme importance to exclude potentially reversible dementias, such as hyperparathyroidism with hypercalcemia, in the differential diagnosis of a rapidly progressive dementia. According to literature, this entity is undervalued and it is highly relevant to be aware of it.
