BACKGROUND High blood pressure, although the main modifiable risk factor for stroke, may have a beneficial effect in maintaining brain perfusion after acute ischemia. The authors assessed the effects of blood pressure variation in the first 24 hours of stroke onset. METHODS The authors prospectively studied consecutive patients admitted in the first 24 hours after stroke onset. Patients were ...

BACKGROUND AND OBJECTIVES Since the first reported anesthetic death, many attempts have been made to study the incidence of risk factors, complications and mortality associated to anesthesia and surgery. The estimated perioperative mortality risk varies from 0.05 to 10 cases per 10,000 anesthesias. This study aimed at reporting the incidence of anesthetic-surgical death in the first 24 hours, a...

After the introduction of the hepatitis B vaccine in the United States in 1982, a greater than 90% reduction in new infections was achieved. However, approximately 1000 new cases of perinatal hepatitis B infection are still identified annually in the United States. Prevention of perinatal hepatitis B relies on the proper and timely identification of infants born to mothers who are hepatitis B s...

Successful outcome is more likely with early treatment and lesser degrees of acidosis. While aiming for maximum treatment for the first 24 hours, some patients improve so rapidly that they can discontinue after a shorter time. Most patients need a full face mask and oxygen, and nebulised bronchodilators can be incorporated. If radiological consolidation, excessive secretions and/or confusion ar...

BACKGROUND Magnesium sulphate is a neuroprotective agent that might improve outcome after aneurysmal subarachnoid haemorrhage by reducing the occurrence or improving the outcome of delayed cerebral ischaemia. We did a trial to test whether magnesium therapy improves outcome after aneurysmal subarachnoid haemorrhage. METHODS We did this phase 3 randomised, placebo-controlled trial in eight cen...

Colostrum is the first milk secreted by a sow during lactation and is produced for just 24 hours following the onset of farrowing. The substance is rich in energy, and contains antibodies and immunoglobulins required by the piglet to fight disease and infection. At birth, energy reserves in piglets are very low and the immune system is extremely immature. Colostrum provides energy and the passi...
