The efficacy of a treatment and teaching programme for non-insulin-treated Type 2 diabetic patients in general practice was evaluated in a prospective, controlled study. In a rural area in southern Austria, 53 patients from seven general practices participated in a structured programme (intervention group) and 55 patients from seven general practices without the programme served as the control group. After 6 months the weight reduction in the intervention group was 2.6 kg (1.6-3.7 kg, p < 0.001) and the difference in HbA1c between the groups was 0.92% (0.23-1.61%, p < 0.01) at follow-up. Systolic (-16.6 mmHg) and diastolic (-11.1 mmHg) blood pressure, serum triglycerides (-0.63 mmol I-1), and serum cholesterol (-0.40 mmol I-1) were reduced significantly in the intervention group (p < 0.006). The number of patients with callus formation and poor nail care decreased significantly after participating in the teaching programme (p < 0.001). In the control group no reduction in body weight, metabolic control or in risk factors for diabetic foot complications were observed. Calculated health care costs per patient and year decreased in the intervention group (-33 pounds) and increased in the control group (+ 30 pounds) mainly due to changes in prescription of oral hypoglycaemic agents in both groups. This programme may be an efficient and helpful model to increase overall quality of diabetes care according to the St Vincent Declaration.
An excellent correlation is observed between a CC genotype and a positive H2 test, whereas the correlation between a TC or TT genotype and a negative H2 test result is less strong. Analysis of the -13910 T/C variant can be considered a good test for predicting the presence of lactase non-persistence in a patient population with suspected lactose malabsorption.
To quantitatively assess the role of Candida species in antibiotic-associated diarrhea (AAD), stool samples from a total of 395 patients and control subjects were cultured in differential isolation medium: 98 patients had AAD, 93 patients were taking antibiotics but did not have diarrhea (A(+)D(-)), 97 patients were not taking antibiotics but had diarrhea (A(-)D(+)), and 107 patients were control subjects (A(-)D(-)). In addition, secreted aspartyl proteinase (Sap) production was tested. In AAD patients, Candida positivity (77/98) and Candida overgrowth (62/98) were not different from that among A(+)D(-) patients (75/93 [P= .860] and 52/93 [P= .375], respectively). Candida overgrowth among A(-)D(+) patients (40/97, P= .003) was less frequent than among AAD patients, but Candida positivity was not different (80/97, P= .612). In control subjects, Candida positivity and overgrowth were less common than in all other groups. Production of Sap did not differ between patients with AAD and control subjects (P= .568 and P= .590, respectively). Data indicate that elevated Candida counts are a result of antibiotic treatment or diarrhea rather than a cause of AAD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
