OBJECTIVE Diabetes-related lower-extremity amputation (LEA) rates are elevated in blacks compared with whites in the U.S., but are lower in African Caribbeans in the U.K., whereas anecdotal reports suggest high rates in the Caribbean. We aimed to establish the incidence and risk factors for diabetes-related LEA in a Caribbean population. RESEARCH DESIGN AND METHODS We conducted an incident an...

OBJECTIVE Compare GHb among people with diabetes who have and have not received periodontal care. RESEARCH DESIGN AND METHODS This cross-sectional study linked 5 years of electronic medical record and dental insurance data for dually insured patients with diabetes, ages 40-70 years (n = 5,103). We assessed the association between annual mean GHb (%) and periodontal care (a proxy for periodont...

Very low density lipoprotein overproduction is the major metabolic characteristic in familial combined hyperlipidemia (FCHL). Peripheral handling of free fatty acids (FFAs) in vitro may be impaired in FCHL by decreased action of acylation-stimulating protein (ASP), which is identical to the immunologically inactive complement component 3a (C3adesArg). Because decreased FFA uptake by impaired co...

The most common chemicals that can be ingested and lead to greater than endogenous levels of gamma-hydroxybutyric acid (GHB) in decedents are salts of GHB, gamma-butyrolactone (GBL), and 1,4-butanediol (BD). Results for three deaths involving the ingestion of one or another of these three chemicals, which led to findings of GHB in the decedents, are presented. An extraction procedure that facil...

A growing body of evidence shows that gamma-hydroxybutyric acid (GHB) is an addictive substance. Its precursors gammabutyrolactone (GBL) and 1,4-butanediol (1,4-BD) show the same properties and may pose even more risks due to different pharmacokinetics. There are indications that problematic GHB use is increasing in the European Union. This review investigates the existing literature on the neu...

OBJECTIVE Type 2 diabetes is a serious disease that is commonly undetected and for which screening is sometimes advocated. A number of risk factors are associated with prevalent undiagnosed diabetes. The use of routinely available information on these factors has been proposed as a simple and effective way of identifying individuals at high risk for having the disease. The objective of this stu...

The objective of this study was to describe a 12-year (1997-2008) observation of substance-related incidents occurring at rave parties in the Netherlands, including length of visits to first-aid stations, substances used, and severity of the incidents. During rave parties, specifically trained medical and paramedical personnel staffed first aid stations. Visitors were diagnosed and treated, and...

The objective of this study was the development of an accurate and sensitive method for the determination of gamma-hydroxybutyric acid (GHB) in dried whole blood samples using a GC-MS method. The complete procedure was optimized, with special attention on the sample pretreatment, and validated. Therefore, dried blood spots of only 50 μl were prepared and, after the addition of internal standard...
