ABSTRACT
BACKGROUND: In type 1 diabetes mellitus (T1DM) management, enhancing health-related quality of life (HRQoL) is as important as good metabolic control and prevention of secondary complications. This study aims to evaluate possible regional differences in HRQoL, demographic features and clinical characteristics of patients with T1DM in Brazil, a country of continental proportions, as well as investigate which variables could influence the HRQoL of these individuals and contribute to these regional disparities. METHODS: This was a retrospective, cross-sectional, multicenter study performed by the Brazilian Type 1 Diabetes Study Group (BrazDiab1SG), by analyzing EuroQol scores from 3005 participants with T1DM, in 28 public clinics, among all geographical regions of Brazil. Data on demography, economic status, chronic complications, glycemic control and lipid profile were also collected. RESULTS: We have found that the North-Northeast region presents a higher index in the assessment of the overall health status (EQ-VAS) compared to the Southeast (74.6 ± 30 and 70.4 ± 19, respectively; p < 0.05). In addition, North-Northeast presented a lower frequency of self-reported anxiety-depression compared to all regions of the country (North-Northeast: 1.53 ± 0.6; Southeast: 1.65 ± 0.7; South: 1.72 ± 0.7; Midwest: 1.67 ± 0.7; p < 0.05). These findings could not be entirely explained by the HbA1c levels or the other variables examined. CONCLUSIONS: Our study points to the existence of additional factors not yet evaluated that could be determinant in the HRQoL of people with T1DM and contribute to these regional disparities.
ABSTRACT
OBJECTIVE: To evaluate the accuracy of potassium concentrations measured by blood gas analysis (PBG) compared with laboratory serum potassium (LSP), in the initial care of patients with diabetic ketoacidosis (DKA). SUBJECTS AND METHODS: Fifty three patients with diabetes mellitus were evaluated in a retrospective analysis. PBG was carried out using the Radiometer ABL 700 (Radiometer Copenhagen(®)), and results were compared with LSP ADVIA 1650 Chemistry system (Siemens(®)), the gold standard method. Both methods are based on potentiometry. RESULTS: Mean PBG was 3.66 mmol/L and mean LSP was 4.79 mmol/L. Mean difference between PBG and LSP was -1.13 mmol/L (p < 0.0005, 95% CI, -1.39 to -0,86). Lin concordance correlation coefficient was rc = 0.28 (95% CIb, 0.10 to 0.45), demonstrating low concordance between the methods. CONCLUSION: Although PBG measurement is faster and easier, it should not be used as a surrogate for LSP in the clinical treatment of DKA.

OBJETIVO: Avaliar a acurácia da mensuração da concentração de potássio realizado nos analisa-dores de gasometria sanguínea (PGS) em relação ao potássio plasmático laboratorial (PPL) no atendimento inicial dos pacientes com cetoacidose diabética (CAD). SUJEITOS E MÉTODOS: Foram avaliados, retrospectivamente, 53 pacientes com diabetes melito e CAD. A análise do PGS foi realizada pelo equipamento ABL 700 (Radiometer Copenhagen®), sendo este comparado ao método padrão-ouro de PPL ADVIA 1650 (Siemens®), ambos por potenciometria. RESULTADOS: A média do PGS foi de 3,66 mmol/L e do PPL, de 4,79 mmol/L. A diferença das médias do PGS em relação ao PPL foi de -1,13 mmol/L (p < 0,0005, IC = 95 por cento; -1,39 a -0,86). O coeficiente de concordância de Lin foi de rc = 0,28 (ICb = 95 por cento; 0,10 a 0,45), demonstrando, assim, uma baixa concordância entre os métodos. CONCLUSÃO: Apesar de a realização do PGS ser tecnicamente mais rápida e fácil, não deve ser usada como parâmetro substituto ao PPL para o tratamento clínico da CAD.

This paper evaluate the efficacy and patients preferences of glucose monitoring in alternatives sites: ear lobe, forearm and calf against conventional fingerstick. We studied 89 patients (39 M/ 50 F) with type 2 diabetes mellitus (DM2). Glucose monitoring was measured using a digital glucosimeter (ACCU - CHEK Performa, Roche), and ACCU-CHEK Multiclix lancetador, with grade 5 on the distal phalange on the right hand's third finger, inferior part of right ear lobe, right forearm and right calf. There was not statistical significance on the comparative analyzes of fingerstick and alternatives sites. There was more pain in fingerstick. The patients preferred the fingerstick and the ear lobe. Glucose monitoring in alternative sites is as simple, safe and efficient as fingerstick.

O trabalho visa avaliar eficácia e a preferência dos pacientes na monitorização da glicemia capilar em locais alternativos: lóbulo de orelha, antebraço e panturrilha em relação à ponta de dedo. Foram avaliados 89 pacientes (39 M/50 F) com diabetes melito tipo 2 (DM2). A monitorização foi feita com glicosímetro digital (ACCU - CHEK Performa, Roche), lancetador ACCU-CHEK Multiclix, em grau 5 na face palmar da falange distal do 3º dedo da mão direita, porção inferior do lóbulo da orelha direita, antebraço direito e região superior da panturrilha direita. Não houve diferença da glicemia capilar na ponta de dedo em relação aos locais alternativos. A ponta de dedo foi o local mais doloroso. Quanto ao local de preferência, a orelha e a ponta de dedo foram os preferidos. A monitorização glicêmica em locais alternativos é simples, segura e eficaz, como a glicemia de ponta de dedo.
