Impact of Glucose Exposure on Outcomes of a Nation-Wide Peritoneal Dialysis Cohort - Results of the BRAZPD II Cohort.

Background: Data investigating the association of glucose exposure with technique failure and patient survival are limited to retrospective cohorts and was never tested outside Asia and considering the presence of competing risks. Methods: Prospective multicenter cohort study of incident peritoneal dialysis patients where the association of cumulative glucose exposure in 6, 12, and 24 months with patient survival and technique failure was tested using Cox regression analysis and competing risk analysis. Results: We analyzed 4367 incident peritoneal dialysis patients with mean age 59.0 ± 15.8 years, 43.9% were diabetics, 46.7% males and 64.4% Caucasians. Glucose exposure was not associated with patient survival independent of the time of exposure and even after adjustments for confounders. In contrast, higher glucose exposure was associated with more technique failure in the Cox and competing risk models. The higher risk for technique failure was found in the subgroup exposed to the higher amount of glucose to a maximum of 86% in the model analyzing cumulative glucose exposure for 1 year. Conclusion: Glucose exposure was associated with technique failure but not with patient survival.

Influence of treatment in multiple sclerosis disability: an open, retrospective, non-randomized long-term analysis.

UNLABELLED: The efficacies of immunosuppressive (IMS) and immunomodulatory (IMM) drugs for multiple sclerosis (MS) have been reported in several studies. These agents can reduce relapse rates and lesions observed by magnetic resonance imaging studies. However, the effect of these medications in disability progression over 4 years is rarely examined. OBJECTIVE: To study the disabilities associated with MS patients after a long time period and to analyze the therapeutic influence of different types of treatments in patient disease progression. METHOD: This is an open, uncontrolled, non-randomized, retrospective study of the disease progression using the Expanded Disability Status Scale (EDSS) and the Multiple Sclerosis Severity Score (MSSS) in 155 cases of MS, which were 76% female with a mean age of onset of 30.21+/-9.70. The follow-up period was 115.39+/-88.08 months (median 92, 3 to 447 months). These cases were submitted to the following 277 different therapeutic procedures: 62 without IMS or IMM therapy (SYT) (just corticosteroids), 53 with azathioprine (AZA), 53 interferon-beta (IFNbeta)-1b 250 microg (BET), 55 IFNbeta-1a 22 microg (R22), 19 IFNbeta-1a 30 microg (AVO), 15 IFNbeta-1a 44 microg (R44), 15 glatiramer acetate (COP) 20 mg, and 5 cases with mitoxantrone (MIT). RESULTS: The median EDSS group was 2.00 (0 to 5.5, mean 1.89+/-1.52) at the onset of each treatment and 2.50 (0 to 9, mean 3.06+/-2.18) at the end. The median initial MSSS was 3.34 (0.25 to 9.50, mean 3.94+/-2.91) and the final medial was 3.90 (0.05 to 9.88, mean 4.02+/-2.78). The EDSS between initial and final score for the whole group had statistically significant progression, as well as for the sub-groups SYT, AZA, BET and R22. No statistically significance difference was found in the MSSS between initial and final scores in the whole group or treatment sub-groups. The variation between the initial and final EDSS and MSSS among the types of treatments found no statistical significance for any group. CONCLUSION: In this study series, no statistical difference was found in the long-term progression of disability among the IMS and IMM treated cases, nor in the cases treated only with corticosteroids.

A eficácia das medicações imunossupressivas (IMS) e imunomoduladoras (IMM) na esclerose múltipla (MS) tem sido relatada em diversos estudos. Essas medicações podem reduzir o número de surtos e de lesões observadas nos estudos de ressonância magnética. Entretanto, o efeito dessas medicações na progressão da incapacidade em período acima de quatro anos é raramente estudado. OBJETIVO: Estudar a incapacidade associada à MS em longo prazo e analisar os benefícios dos diferentes tipos de tratamento na progressão da doença. MÉTODO: Estudo aberto e retrospectivo da progressão da incapacidade utilizando a escala expandida do grau de incapacidade (EDSS) e o escore da gravidade da esclerose múltipla (MSSS) em 155 casos de MS, sendo 76 por cento do sexo feminino, idade média no início da doença 30,21±9,70 anos e período médio de seguimento 115,39±77,08, mediana 92 (3 a 447) meses. Os casos foram submetidos a 277 tipos diferentes de tratamentos: 62 casos não usaram IMS ou IMM, somente corticosteróides (SYT); 53 com azatioprina (AZA); 53 com interferon-β (IFNβ)-1b 250 µg (BET); 55 com IFNβ-1a 22 µg (R22); 19 com IFNβ-1a 30 µg (AVO); 15 com IFNβ-1a 44 µg (R44); 15 com acetato de glatiramer (COP) 20 mg, e 5 casos com mitoxantrone (MIT). RESULTADOS: A mediana do EDSS do grupo foi 2,0 (0 a 5,5, média total do grupo foi 1,89±1,52) no início de cada tratamento e 2,50 (0 a 9, média de 3,06±2,18) no fim. A mediana inicial da MSSS foi 3,34 (0,25 a 9,50, média 3,94±2,91) e a final 3,90 (0,05 a 9,88, média 4,02±2,78). O EDSS entre o início e o fim do tratamento do grupo mostrou progressão estatisticamente significante e também para os subgrupos SYT, AZA, BET e R22. Não foi encontrada diferença estatística no MSSS entre o início e fim do tratamento no grupo total ou nos subgrupos. Não foi encontrada diferença estatisticamente significante entre a variação inicial e final do EDSS e MSSS entre os diversos subgrupos de tratamento...

Estudo comparativo da ação dos fios: categut cromado, poliglactina 910 e polidioxanona na cicatrização de bexiga de ratos / Comparative study of the suture cicatrization in bladder of rats performed with chromic catgut, polyglaction 910 and polydioxanone suture

O objetivo deste trabalho foi comparar o efeito de diferentes fios - categut cromado, polidioxanona (PDS) e poliglactina (Vicryl) - sobre a cicatrização de bexiga em ratos. Utilizaram-se 120 ratos machos Wistar, divididos aleatoriamente em grupos C (CATEGUT CROMADO), v (vICRYL) e P (PDS), sendo que em cada grupo procedeu-se a cistotomia e sutura com 3 pontos separados com o fio específico. Cada grupo foi subdividido em quatro , 15subgrupos de 40 animais e avaliados no 7º, 15º, 45º e 60º dia de pós-operatório. Os resultados permitiram concluir que não houve diferença significativa intra ou entre os grupos para: formação de aderências, indução a litogênese e resposta inflamatória celular crônica. Para reação inflamatória celular aguda na avaliação intra grupos diferença no grupo Categut (p=0,008) e Vicryl (p=0,002) com respostas decrescentes. Para fibrose observou-se na avaliação entre os grupos diferença significativa no 7º dia (p=0,002) para o grupo PDS com reação mais acentuada e na análise intragrupo, diferença significativa para grupo Vicryl (p=0,005) com reação menos acentuada.
