Alpha taxonomy of the Russian Permian procolophonoids

European Russia has been the source of many procolophonoid taxa from both the Permian and Triassic, and a Permian or− igin for the procolophonoid family Procolophonidae has been based on the Russian taxon Microphon exiguus. Recently, this taxon was reclassified as a seymouriamorph and, in its place, the taxa Nyctiphruretus, Suchonosaurus, and Kinelia from the Middle and Upper Permian of Russia were suggested as “procolophons”, using evolutionary−systematic classifi− cation methods. In recent phylogenies, however, Nyctiphruretus has been recovered as a non–procolophonoid para− reptile, whereas Kinelia and Suchonosaurus have never been included in a phylogenetic study. Re−examination indicates that Suchonosaurus is a member of the procolophonoid subfamily Procolophonidae based on the shape of the maxillary bone and the external naris, the laterally visible maxillary depression, and the number and type of maxillary teeth. Kinelia, on the other hand, is excluded from the Procolophonoidea because of its subpleurodont dental attachment and lack of any procolophonoid features. Thus, Suchonosaurus is the only confirmed Permian procolophonid from the Permian of Rus− sia. Additionally, re−examination of the holotype of Microphon exiguus confirms that it is identical to the seymouria− morph specimens recently included in the genus Microphon and that it lacks procolophonoid features. The earliest un− equivocal record of the subfamily Procolophonidae is confirmed from the Late Permian of Russia, making Russia the only region where, with certainty, both Permian and Triassic procolophonids have been discovered

Nationwide Multicenter Study On The Prevalence Of Overweight And Obesity In Type 2 Diabetes Mellitus In The Brazilian Population [prevalência De Sobrepeso E Obesidade Em Pacientes Com Diabetes Mellitus Do Tipo 2 No Brasil: Estudo Multicêntrico Nacional]

Aim: To evaluate the prevalence of overweight and obesity in type 2 diabetic (DM2) outpatients from different regions of Brazil. Patients and Methods: We studied 2,519 randomly selected patients, from 11 hospitals, 2 endocrine and one general public care clinics from 10 cities. Overweight was defined as body-mass index (BMI) > 25 and obesity as BMI > 30 kg/m 2. Glycemic control (GC) was evaluated by GC index (GCI= patient's HbA 1 or HbA 1c/upper limit of normal for the method x 100). Results: 39% of the population studied was male, the mean age was 58.8 ± 11.6 y, the duration from clinical diagnosis of DM2 was 9.0 ± 7.3y, and BMI was 28.3 ± 5.2 kg/m 2. No measurements of BMI were recorded from 265 patients (10.5%). Patients from the Northeast presented lower BMI as compared with those from the Midwest, Southeast and South areas, respectively (26.4 ± 4.7 vs. 27.9 ± 4.8 vs. 29.2 ± 5.1 vs. 29.4 ± 5.4 kg/m 2; p< 0.001). A greater prevalence of obesity was observed in the Southeast and South areas as compared to the Northeast (p< 0.001), as well as in the female group, respectively (69% vs. 31%; p< 0.001). Normal weight patients presented lower GCI. Patients being treated with two or more oral drugs and an association of insulin plus oral drug presented greater BMI values than those being treated with diet, oral hypoglycemic agents and insulin p< 0.001. The BMI of patients treated by a specialist did not differ from those treated by a generalist. Conclusions: 75% of our sample was out of adequate BMI and 30% was obese. The percentage of patients with overweight and obesity was comparable to those found in similar European studies but still lower than those found in the USA. The prevalence of obesity in diabetic patients was three times higher than in the overall Brazilian population according to data from the Brazilian Institute of Geography and Statistics (IBGE).501136144(1997) Obesity: Preventing and Managing the Global Epidemic, , GenevaMONICA Project: Risk Factors (1989) Int J Epidemiol, 18 (1 SUPPL.), pp. S46-55Grundy, S.M., Brewer, B., Cleeman, J.I., Smith, S.C., Lenfant, C., Report of the National Heart, Lung, and Blood Institute/American Heart Association Conference on Scientific Issues Related to Definition (2004) Circulation, 109, pp. 433-438Knowler, W.C., Barrett-Connor, E., Fowler, S.E., Hamman, R.F., Lachin, J.M., Walker, E.A., Reduction in the incidence of type 2 diabetes with lifestyle intervention or metformin (2002) N Engl J Med, 346, pp. 393-403Erberly, L.E., Cohen, J.D., Prineas, R., Yang, L., (2003) Diabetes Care, 26, pp. 848-854. , For the Multiple Risk factor Intervention Trial Research GroupHaffner, S.M., Lehto, S., Ronemaa, T., Pyorala, K., Laakso, M., Mortality from coronary heart disease in subjects with type 2 diabetes and non diabetic subjects with and without prior myocardial infarction (1998) N Engl J Med, 339, pp. 229-234Cunha, E.F., Marques, E.P., Gomes, M.B., Perfil de pacientes diabéticos internados em Hospital Universitário do Rio de Janeiro (1995) Arq Bras Endocrinol Metab, 39, pp. 111-115Wild, S., Roglic, G., Green, A., Sicree, R., King, H., Global prevalences of diabetes.
