Factors associated with recurrent transient global amnesia: systematic review and pathophysiological insights.

The examination of the risk factors that affect the recurrence of transient global amnesia (TGA) may shed light on the pathophysiological substrate of the disease. A systematic review was performed to identify the factors associated with the recurrence of TGA. MEDLINE, EMBASE, CENTRAL and PsycINFO were meticulously searched.

The long-term prognosis of Transient Global Amnesia: a systematic review.

Transient Global Amnesia (TGA) constitutes an enigmatic amnestic condition. In view of the admittedly limited knowledge regarding the nature of TGA, we decided to systematically review existing evidence for the generally regarded benign course of the disease. MEDLINE, EMBASE, CENTRAL and PsycINFO were searched for relevant articles.

Conventional cardiovascular risk factors in Transient Global Amnesia: Systematic review and proposition of a novel hypothesis.

Transient Global Amnesia (TGA) is an enigmatic amnestic syndrome. We conducted a systematic review to investigate the relationship between the conventional cardiovascular risk factors and TGA. MEDLINE, CENTRAL, EMBASE and PsycINFO were comprehensively searched and 23 controlled observational studies were retrieved.

High prevalence of elevated liver enzymes in blood donors: associations with male gender and central adiposity.

Objective: Nonalcoholic fatty liver disease is an increasingly recognized condition, but its exact prevalence is unknown. In this prospective, multicenter study, we evaluated the prevalence of elevated alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl-transpeptidase levels as indirect markers of nonalcoholic fatty liver disease in volunteer blood donors as well as their associations with epidemiological and anthropometrical characteristics.

Methods: Alanine aminotransferase, aspartate aminotransferase and gamma-glutamyl-transpeptidase levels were determined in blood donors from four transfusion centers during the morning sessions of a 3-month period.

A viral kinetic study using pegylated interferon alfa-2b and/or lamivudine in patients with chronic hepatitis B/HBeAg negative.

We studied viral dynamic parameters in 44 chronic hepatitis B/hepatitis B e antigen (HBeAg)(-) patients treated with pegylated interferon alfa-2b (PEG-IFN) 100 or 200 microg weekly or lamivudine 100 mg daily or the combination of PEG-IFN 100 or 200 microg with lamivudine. Patients receiving PEG-IFN monotherapy exhibited viral load oscillations between weekly injections, which were resolved by the addition of lamivudine. The median pharmacological delay was estimated at 4.
