RESUMO
OBJECTIVE: to describe the process of developing a terminological subset for the International Classification of Nursing Practice in Diabetes Mellitus, based on Horta's Basic Human Needs Theory and Bandura's Social Cognitive Theory. METHOD: a methodological study based on the identification in the literature of 313 statements of nursing diagnoses pertinent to diabetes care, selected and validated by a consensus of nurses from different states of Brazil, specialists in diabetes, using the nominal group technique. RESULTS: 156 nursing diagnosis/result statements were selected, of which 111 (71.15%) related to psychobiological needs, 42 (26.92%) to psychosocial needs and three (1.92%) to psychospiritual needs. A total of 433 nursing interventions were developed. The diagnostic statements were validated on the basis of a consensus among the experts, with an average content validity index of 0.89: 0.87 for psychobiological needs, 0.93 for psychosocial needs, and 0.77 for psychospiritual needs. CONCLUSION: the study validated the terminological subset for the International Classification of Nursing Practice in Diabetes, favoring clinical reasoning, the qualification of the Nursing Process, and the improvement of self-care practices in diabetes. It has made it possible to use nursing's own language based on a globally recognized classification. (1) Provision of the guiding document for nursing practice in diabetes. (2) Methodological innovation in the development of ICNP® subsets. (3) Advances in knowledge of the basic human needs of people with diabetes. (4) The potential of standardized language for coding and monitoring data. (5) Improving clinical reasoning during nursing consultations.

AIM: To investigate whether eating patterns of specific food groups can be used to predict and classify Mexican adults who have been diagnosed as having obesity, diabetes or both, when compared to those without a diagnosis. Additionally, we aim to show the benefit of data mining techniques in nutritional studies. METHODS: Statistical analysis of self-reported eating patterns based on designated food groups is conducted. Predictive models for health status based on dietary patterns are built using a naïve Bayes classifier. RESULTS: Clear patterns emerge in the model building where adults are categorised as having obesity, diabetes or both. The model for diabetics showed the greatest degree of predictability, producing sensitivity results 2.4 times higher than the average, using score decile testing. The models for people with obesity and for those with both obesity and diabetes both reported sensitivity doubling the average. Coverage also showed greatest response for the diabetic model, the first decile containing 24% of all diabetics. CONCLUSIONS: Classifier models using dietary habits as inputs succeed in subcategorising Mexican adults based on health status. Diabetics are associated with a very different, and more appropriate dietary pattern (significantly less sugar consumption) for their condition, relative to the non-diagnosed group. Adults with obesity are also associated with a very different, but inappropriate (higher overall consumption), dietary pattern. We hypothesise that obesity, unlike diabetes, is not seen as a sufficiently serious condition, leading to an inadequate response to the diagnosis. Furthermore, data mining techniques can provide new results in nutritional studies.

A suplementação diária com ácidos graxos poli-insaturados de ômega-3 (ω-3) e a aspirina em baixa dosagem foram propostas como terapia de modulação do hospedeiro para o tratamento de doenças inflamatórias crônicas. O objetivo deste estudo foi investigar as ações clínicas e imunológicas do ω-3 e da aspirina (AAS) como terapia adjunta ao debridamento periodontal de boca toda para o tratamento da periodontite em pacientes com diabetes tipo 2. Setenta e cinco pacientes (n=25/grupo) que atendiam aos critérios de inclusão foram randomicamente designados para receber placebo e debridamento periodontal (GC), ω-3 (3g de óleo de peixe/dia por 60 dias) e AAS (100mg/dia por 60 dias) após o debridamento periodontal (GT1), e (3g de óleo de peixe/dia por 60 dias) e AAS (100mg/dia por 60 dias) antes do debridamento periodontal (GT2). Parâmetros clínicos periodontais e fluido gengival crevicular (FGC) foram coletados no baseline (t0), 90 dias (GT1 e GC) (t1), após a suplementação/medicação com ω-3 e AAS (t1), e 180 dias após o debridamento periodontal (todos os grupos) (t2). Dez pacientes (40%) no GT1 e nove pacientes (36%) no GT2 alcançaram o endpoint clínico para o tratamento (≤4 bolsas periodontais com profundidade de sondagem (PS)≥ 5mm), em contraste com quatro (16%) no GC. Houve ganho de inserção em bolsas moderadas e em bolsas profundas entre t0 e t2 para o GT1. Os níveis de concentração de IFN-γ, IL-1ß e IL-8 apresentaram redução em t2 para os dois grupos teste, com mudanças significantes prévias (t1) para o GT1. Os níveis de IL-6 apresentaram redução em t1 e em t2 para o GT1, e a MIP-1α reduziu em t2 no GT2. No GC a IL-1ß foi a única citocina a apresentar diferença estatisticamente significante na comparação entre tempos. Os resultados deste estudo clínico sugerem que a terapia adjuvante de ω-3 a AAS após o debridamento periodontal promove maiores benefícios clínicos e imunológicos ao tratamento da periodontite em pacientes com diabetes tipo 2 quando comparado aos demais protocolos avaliados(AU)
Daily dietary supplementation with omega-3 (ω-3) polyunsaturated fatty acids (PUFAs) and low-dose aspirin (ASA) have been proposed as a host modulation therapy for the treatment of chronic inflammatory diseases. The aim of this study was to investigate the clinical and immunological actions of ω-3 PUFAs and ASA as an adjunct therapy to full-mouth periodontal debridement for the treatment of periodontitis in patients with type 2 diabetes. Seventy-five patients (n=25/group) meeting the inclusion criteria were randomly assigned to receive placebo and periodontal debridement (CG), ω-3 (3g of fish oil/day for 60 days) and ASA (100mg/day for 60 days) after periodontal debridement (TG1), and ω-3 (3g of fish oil/day for 60 days) and ASA (100mg/day for 60 days) before periodontal debridement (TG2). Periodontal clinical parameters and gingival crevicular fluid (GCF) were collected at baseline (t0), 90 days (TG1 and CG) (t1), after ω-3 and ASA only (TG2) (t1), and 180 days after periodontal debridement (all groups) (t2). Ten patients (40%) in TG1 and nine patients (36%) in TG2 achieved the clinical endpoint for treatment (≤4 periodontal pockets with probing depth (PD)≥ 5mm), as opposed to four (16%) in CG. There was clinical attachment gain in moderate and deep pockets between t0 and t2 for TG1. Concentration levels of IFN-γ, IL-1ß, and IL-8 decreased over time for both test groups, with early (t1) significant changes for TG1. IL-6 levels were lower at t1 and t2 for TG1, and MIP-1α decreased at t2 for TG2. In the CG, IL1ß was the only marker presenting statistically significant changes over time. The results of this clinical study suggest that the adjunctive use of ω-3 and ASA after periodontal debridement provides clinical and immunological benefits to the treatment of periodontitis in patients with type 2 diabetes when compared to the other treatment protocols evaluated(AU)

Dados mostram que o aparecimento do diabetes mellitus (DM), em pacientes previamente asmáticos, diminui os sintomas da asma, enquanto a insulina agrava a asma. Devido a dados na literatura e por dados prévios do nosso grupo, o presente estudo teve como objetivo avaliar o efeito modulatório da insulina na inflamação alérgica pulmonar em camundongos diabéticos e saudáveis. Camundongos machos dibéticos BALB/c (aloxana, 50mg/kg, iv, 10 dias) foram sensibilizados com ovalbumina (OVA, 20 µg e Al (OH)3, 2 mg) 10 dias após a injeção de aloxana e uma dose reforço foi dada, após 12 dias da primeira de sensibilização, após 6 dias da dose reforço, os animais foram expostos a nebulização durante 7 dias com solução de OVA (1mg/mL) ou solução salina (SAL). Animais diabéticos foram tratados com doses múltiplas de Protamine Hagedorn Neutro (NPH) 2UI e 1UI, respectivamente, por via subcutânea 12 horas antes do desafio com OVA (às 19h) e 1UI (às 7h) 2h antes de cada desafio com OVA. Os animais não diabéticos receberam 1UI de insulina, pela mesma via 2h antes de cada desafio (às 7h), 24h após o último desafio, realizaram-se as seguintes análises: a) expressão de proteína quinase p38, proteína quinase regulada por sinais extracelulares 1 e 2 (ERK 1/2), proteína quinase ativada por estresse ou c-jun NH2- terminal (JNK) , transdutor de sinal e ativador de transcrição 3 (STAT 3) e transdutor de sinal e ativador de transcrição 6 (pSTAT 6) no homogenato de pulmão; b) perfil de imunoglobulinas presentes no soro; c) concentrações de interleucina (IL) IL-4, IL-5, IL-10, IL-13, fator de necrose tumoral alfa (TNF-α), fator de crescimento endotelial vascular (VEGF), fator de crescimento transformador beta (TGF-ß) e interferon-gamma IFN-γ em homogenato de pulmão; d) migração celular em fluído do lavado broncoalveolar (LBA); e) perfil de células imunes na medula óssea, pulmão, timo e baço; f) mecânica pulmonar por BUXCO e FlexiVent. Em comparação com camundongos não diabéticos desafiados com OVA, os animais diabéticos desafiados com OVA mostraram diminuição em: ERK 1, ERK 2, JNK (fosfo54), JNK / SAPK, STAT3, pSTAT6 estava ausente; concentração da imunoglobulinas IgE, IgG1; perfil de citocinas Th2 como IL-4, IL-5, IL-13, TNF-α, VEGF, TGF-ß; infiltrado inflamatório e) ausência de eosinofilia no LBA; células T, células B e eosinófilos na medula óssea, pulmão, timo e baço, e hiper-reatividade das vias aéreas. O tratamento com insulina restaubeleceu todos os parâmetros estudados. Portanto, sugerem que a insulina modula a inflamação alérgica pulmonar tardia em camundongos diabéticos
Data show that the onset of diabetes mellitus (DM) in previously asthmatic patients decreases asthma symptoms while insulin worsens asthma. Due to data in the literature and previous data from our group, the present study aimed to evaluate the modulatory effect of insulin on pulmonary allergic inflammation in diabetic and healthy mice. Ovalbumin (OVA, 20 µg and Al (OH)3, 2 mg) were sensitized at 10 days after alloxan injection and a booster dose was given , after 12 days of the first sensitization, after 6 days of booster dose, the animals were exposed to nebulization for 7 days with OVA solution (1mg / mL) or saline solution (SAL). Diabetic animals were treated with multiple doses of Protamine Hagedorn Neutral (NPH) 2UI and 1UI, respectively, subcutaneously 12 hours prior to challenge with OVA (at 7pm) and 1UI (at 7h) 2h before each challenge with OVA. Non-diabetic animals received 1UI of insulin, via the same route 2h before each challenge (at 7h), 24h after the last challenge, the following analyzes were performed: a) expression of protein kinase p38, protein kinase regulated by extracellular signals 1 and 2 (ERK 1/2), stress-activated or c-jun NH2-terminal protein kinase (JNK), signal transducer and transcriptional activator 3 (STAT 3) and signal transducer and transcriptional activator 6 (pSTAT 6) in the lung homogenate; b) profile of immunoglobulins present in serum; c) concentrations of interleukin (IL) IL-4, IL-5, IL-10, IL-13, tumor necrosis factor alpha (TNF-α), vascular endothelial growth factor (VEGF), transforming TGF-ß) and interferon-gamma IFN-γ in lung homogenate; d) cell migration in bronchoalveolar lavage fluid (BAL); e) profile of immune cells in the bone marrow, lung, thymus and spleen; f) Pulmonary mechanics by BUXCO and FlexiVent. In contrast to non-diabetic mice challenged with OVA, diabetic animals challenged with OVA showed decrease in: ERK 1, ERK 2, JNK (phospho54), JNK / SAPK, STAT3, pSTAT6 was absent; IgE immunoglobulin levels, IgG1; profile of Th2 cytokines such as IL-4, IL-5, IL-13, TNF-α, VEGF, TGF-ß; inflammatory infiltrate e) absence of eosinophilia in BAL; T cells, B cells and eosinophils in the bone marrow, lung, thymus and spleen, and airway hyperreactivity. The insulin treatment restored all parameters studied. Therefore, they suggest that insulin modulates late pulmonary allergic inflammation in diabetic mice

O diabetes mellitus é um grupo heterogêneo de distúrbios metabólicos caracterizado pela hiperglicemia. Indivíduos diabéticos possuem maior susceptibilidade a infecções comparado a indivíduos sadios e a hiperglicemia é um dos principais fatores que contribuem para isso, em parte, por alterar a resposta imune. Sendo assim, os macrófagos, como células essenciais para a resposta inflamatória, podem apresentar importante papel na resposta imune alterada de indivíduos diabéticos. Neste estudo, investigamos como a hiperglicemia modula os macrófagos derivados da medula óssea (BMDMs) sob um estímulo inflamatório. Para realizar este estudo, os BMDMs de camundongos C57BL/6 machos não diabéticos e diabéticos (60 mg/kg de aloxana, iv) (CEUA / FCF / USP-488) foram cultivados sob condições normais de glicose (5,5 mM) e alta concentração de glicose (25 mM ou 40 mM) e estimuladas ou não com lipopolissacarídeo (LPS, 100 ng/mL). Em comparação com os BMDMs dos camundongos não diabéticos, os BMDMs dos camundongos diabéticos estimulados com LPS apresentaram menor expressão de CD38 no tempo basal e após 24 horas, além de menor expressão de receptor do tipo Toll (TLR)-4 na superfície celular, menor capacidade fagocítica e redução na secreção de óxido nítrico, lactato, fator de necrose tumoral- e interleucina (IL)-10, porém apresentaram maior expressão de CD80, CD86 e MHC-II, maior consumo de oxigênio e maior fosforilação em quinase ativada por estresse/quinase Jun-amino-terminal (SAPK/JNK) subunidade p46 e em quinase regulada por sinal extracelular (ERK) subunidade p42, proteína quinase B (AKT) e proteína quinase C (PKC)-δ assim como maior secreção de IL-6. Quando os BMDMs dos camundongos não diabéticos foram cultivados sob condições de alta concentração de glicose in vitro e estimulados com LPS, a expressão de TLR4 e os níveis de óxido nítrico e peróxido de hidrogênio foram reduzidos. Por outro lado, os BMDMs diabéticos que também foram cultivados em alta concentração de glicose in vitro apresentaram níveis aumentados de lactato e fosforilação reduzida em AKT e PKC-δ, porém apresentaram fosforilação aumentada em p46 SAPK/JNK. A alta concentração de glicose parece modificar o comportamento dos macrófagos, afetando diferentes aspectos dos BMDMs diabéticos e não diabéticos sob estímulo de LPS, assim a hiperglicemia deixa um legado de glicose, induzindo uma memória glicêmica, alterando o estado basal dos macrófagos, modificando a via de sinalização do TLR4 contribuindo para a susceptibilidade de indivíduos diabéticos a infecções
Diabetes mellitus is a heterogeneous group of metabolic disorders characterized by hyperglycemia. Diabetic individuals are more susceptible to infections compared to healthy subjects, and hyperglycemia is one of the major contributing factors, partly because they alter the immune response. Thus, macrophages, as essential cells for the inflammatory response, may play an important role in the altered immune response of diabetic individuals. In this study, we investigated how hyperglycemia modulates bone marrow derived macrophages (BMDMs) under an inflammatory stimulus. To perform this study, BMDMs from non-diabetic male and diabetic C57BL/6 mice (60 mg / kg aloxane, iv) (CEUA / FCF / USP-488) were cultured under normal glucose conditions (5.5 mM) and high glucose concentration (25 mM or 40 mM) and stimulated or not with lipopolysaccharide (LPS, 100 ng / ml). Compared to non-diabetic mice BMDMs, the BMDMs of LPS-stimulated diabetic mice showed lower expression of CD38 at baseline and after 24 hours, as well as lower Toll-like receptor (TLR)-4 on the cell surface, lower secretion of lactate, tumor necrosis factor-, and interleukin (IL)-10, but showed higher expression of CD80, CD86 and MHC-II, higher oxygen consumption and greater phosphorylation in stress-activated kinase/Jun-amino-terminal kinase (SAPK / JNK) p46 subunit and in extracellular signal regulated kinase (ERK) p42 subunit, protein kinase B (AKT) and protein kinase C (PKC)-δ as well as higher secretion of IL-6. When the BMDMs of nondiabetic mice were cultured under conditions of in vitro high glucose concentration and stimulated with LPS, the levels of TLR4 expression, nitric oxide and hydrogen peroxide were reduced. On the other hand, diabetic BMDMs that were also cultured in high glucose concentration of glucose in vitro showed increased levels of lactate and reduced phosphorylation in AKT and PKC-δ, but showed increased phosphorylation in p46 SAPK/JNK. A high glucose concentration seems to modify the behavior of macrophages, affecting different aspects of diabetic and non-diabetic BMDMs under the same LPS stimulus. Hyperglycemia leaves a glucose legacy, inducing a glycemic memory, altering the basal state of macrophages, modifying the TLR4 signaling pathway, and may play a key role in the high susceptibility of diabetic individuals to infections

Study Objectives: A recent study of patients with moderate-severe obstructive sleep apnea (OSA) in Iceland identified three clinical clusters based on symptoms and comorbidities. We sought to verify this finding in a new cohort in Iceland and examine the generalizability of OSA clusters in an international ethnically diverse cohort. Methods: Using data on 972 patients with moderate-severe OSA (apnea-hypopnea index [AHI] ≥ 15 events per hour) recruited from the Sleep Apnea Global Interdisciplinary Consortium (SAGIC), we performed a latent class analysis of 18 self-reported symptom variables, hypertension, cardiovascular disease, and diabetes. Results: The original OSA clusters of disturbed sleep, minimally symptomatic, and excessively sleepy replicated among 215 SAGIC patients from Iceland. These clusters also generalized to 757 patients from five other countries. The three clusters had similar average AHI values in both Iceland and the international samples, suggesting clusters are not driven by OSA severity; differences in age, gender, and body mass index were also generally small. Within the international sample, the three original clusters were expanded to five optimal clusters: three were similar to those in Iceland (labeled disturbed sleep, minimal symptoms, and upper airway symptoms with sleepiness) and two were new, less symptomatic clusters (labeled upper airway symptoms dominant and sleepiness dominant). The five clusters showed differences in demographics and AHI, although all were middle-aged (44.6-54.5 years), obese (30.6-35.9 kg/m2), and had severe OSA (42.0-51.4 events per hour) on average. Conclusions: Results confirm and extend previously identified clinical clusters in OSA. These clusters provide an opportunity for a more personalized approach to the management of OSA.

SUMMARY Identification of the correct etiology of diabetes brings important implications for clinical management. In this report, we describe a case of a 4-year old asymptomatic girl with diabetes since age 2, along with several individuals in her family with different etiologies for hyperglycemia identified in youth. Genetic analyses were made by Sanger sequencing, laboratory measurements included HbA1c, lipid profile, fasting C-peptide, pancreatic auto-antibodies (glutamic acid decarboxylase [GAD], Islet Antigen 2 [IA-2], and anti-insulin). We found a Gly178Ala substitution in exon 5 of GCK gene in three individuals co-segregating with diabetes, and type 1 diabetes was identified in two other individuals based on clinical and laboratory data. One individual with previous gestational diabetes and other with prediabetes were also described. We discuss difficulties in defining etiology of hyperglycemia in youth in clinical practice, especially monogenic forms of diabetes, in spite of the availability of several genetic, laboratory, and clinical tools.

BACKGROUND AND OBJECTIVE: Recent progression towards precision medicine has encouraged the use of electronic health records (EHRs) as a source for large amounts of data, which is required for studying the effect of treatments or risk factors in more specific subpopulations. Phenotyping algorithms allow to automatically classify patients according to their particular electronic phenotype thus facilitating the setup of retrospective cohorts. Our objective is to compare the performance of different classification strategies (only using standardized problems, rule-based algorithms, statistical learning algorithms (six learners) and stacked generalization (five versions)), for the categorization of patients according to their diabetic status (diabetics, not diabetics and inconclusive; Diabetes of any type) using information extracted from EHRs. METHODS: Patient information was extracted from the EHR at Hospital Italiano de Buenos Aires, Buenos Aires, Argentina. For the derivation and validation datasets, two probabilistic samples of patients from different years (2005: nâ¯=â¯1663; 2015: nâ¯=â¯800) were extracted. The only inclusion criterion was age (≥40 & <80 years). Four researchers manually reviewed all records and classified patients according to their diabetic status (diabetic: diabetes registered as a health problem or fulfilling the ADA criteria; non-diabetic: not fulfilling the ADA criteria and having at least one fasting glycemia below 126â¯mg/dL; inconclusive: no data regarding their diabetic status or only one abnormal value). The best performing algorithms within each strategy were tested on the validation set. RESULTS: The standardized codes algorithm achieved a Kappa coefficient value of 0.59 (95% CI 0.49, 0.59) in the validation set. The Boolean logic algorithm reached 0.82 (95% CI 0.76, 0.88). A slightly higher value was achieved by the Feedforward Neural Network (0.9, 95% CI 0.85, 0.94). The best performing learner was the stacked generalization meta-learner that reached a Kappa coefficient value of 0.95 (95% CI 0.91, 0.98). CONCLUSIONS: The stacked generalization strategy and the feedforward neural network showed the best classification metrics in the validation set. The implementation of these algorithms enables the exploitation of the data of thousands of patients accurately.

BACKGROUND: Current classification of diabetes mellitus (DM) is based on etiology and includes type 1 (T1DM), type 2 (T2DM), gestational, and other. Clinical and pathophysiological characteristics of T1DM and T2DM in the same patient have been designated as type 1.5 DM (T1.5DM). OBJECTIVES: The aim of this study was to classify pediatric patients with DM based on pancreatic autoimmunity and the presence or absence of overweight/obesity, and to compare the clinical, anthropometric, and biochemical characteristics between children in the different classes of DM. METHODS: A sample of 185 patients, recruited (March 2008-April 2015) as part of the Cohort of Mexican Children with DM (CMC-DM); ClinicalTrials.gov, identifier: NCT02722655. The DM classification was made considering pancreatic autoimmunity (via antibodies GAD-65, IAA, and AICA) and the presence or absence of overweight/obesity. Clinical, anthropometric and biochemical variables, grouped by type of DM were compared (Kruskal-Wallis or chi-squared test). RESULTS: The final analysis included 140 children; 18.57% T1ADM, 46.43% T1BDM, 12.14% T1.5DM, and 22.86% T2DM. Fasting C-Peptide (FCP), and hs-CRP levels were higher in T1.5DM and T2DM, and the greatest levels were observed in T1.5DM (p<0.001 and 0.024 respectively). CONCLUSIONS: We clearly identified that the etiologic mechanisms of T1DM and T2DM are not mutually exclusive, and we detailed why FCP levels are not critical for the classification system of DM in children. The findings of this study suggest that T1.5DM should be considered during the classification of pediatric DM and might facilitate more tailored approaches to treatment, clinical care and follow-up.

ABSTRACT denosine deaminase (ADA) is a critical control point in the regulation of adenosine levels. This study aimed to investigate the effects of a polyphenolic flavonoid, rutin, on the activity of ADA in serum, the cerebral cortex, liver, kidney, and biochemical parameters in diabetic rats. The animals were divided into four groups (n=6) for the following treatments: control; diabetic (streptozotocin 55 mg/kg); diabetic with rutin (100 mg/kg/day); diabetic with glibenclamide (10 mg/kg/day). After 30 days, ADA activity and biochemical parameters were analyzed. The ADA activity in the serum was significantly elevated in the diabetic group compared to the control group (p<0.01). The treatment with rutin prevented the increase in ADA activity in the STZ-induced rats when compared to control group. Our data showed that rutin reduced glucose, LDL levels, and hepatic enzymes in comparison with the control group. These results demonstrate that the increase of ADA activity observed in diabetic rats may be an important indicator of the immunopathogenesis of hyperglycemic disorders and suggest that rutin is important for regulating the enzymatic activities associated with immune, hyperglycemic, and inflammatory response in diabetes mellitus.
RESUMO A Adenosina desaminase (ADA) representa um ponto de controle crítico na regulação dos níveis de adenosina. A rutina, um flavonóide polifenólico presente em muitas plantas, foi testado para verificar a sua influência na atividade da ADA no soro, córtex cerebral, fígado rim e parâmetros bioquímicos em ratos diabéticos. Os animais foram divididos em quatro grupos cada grupo com 6 animais), tal como: controle; diabética (estreptozotocina 55 mg/kg); diabética + rutina (100 mg/kg/dia); diabético + glibenclamida (10 mg/kg/dia). Após 30 dias foram analisadas a atividade da ADA sérica e tecidual e parâmetros bioquímicos. A atividade de ADA no soro foi significativamente elevada no grupo diabético quando comparado ao grupo controle (p<0,01). O tratamento com Rutina preveniu o aumento na atividade da ADA nos ratos diabéticos, quando comparado com o grupo controle. Os resultados mostraram que a rutina reduziu a glicose, os níveis de LDL e as enzimas hepáticas, em comparação com o grupo controle. Estes resultados mostram que o aumento da atividade da ADA observado em ratos diabéticos pode ser um indicador importante da imuno-patogênese de perturbações hiperglicêmicas e sugerem que a Rutina é importante na regulação das atividades enzimáticas associadas com a resposta imunitária, hiperglicêmica e inflamatória no Diabetes mellitus.

OBJECTIVE: To assess problem list completeness using an objective measure across a range of sites, and to identify success factors for problem list completeness. METHODS: We conducted a retrospective analysis of electronic health record data and interviews at ten healthcare organizations within the United States, United Kingdom, and Argentina who use a variety of electronic health record systems: four self-developed and six commercial. At each site, we assessed the proportion of patients who have diabetes recorded on their problem list out of all patients with a hemoglobin A1c elevation>=7.0%, which is diagnostic of diabetes. We then conducted interviews with informatics leaders at the four highest performing sites to determine factors associated with success. Finally, we surveyed all the sites about common practices implemented at the top performing sites to determine whether there was an association between problem list management practices and problem list completeness. RESULTS: Problem list completeness across the ten sites ranged from 60.2% to 99.4%, with a mean of 78.2%. Financial incentives, problem-oriented charting, gap reporting, shared responsibility, links to billing codes, and organizational culture were identified as success factors at the four hospitals with problem list completeness at or near 90.0%. DISCUSSION: Incomplete problem lists represent a global data integrity problem that could compromise quality of care and put patients at risk. There was a wide range of problem list completeness across the healthcare facilities. Nevertheless, some facilities have achieved high levels of problem list completeness, and it is important to better understand the factors that contribute to success to improve patient safety. CONCLUSION: Problem list completeness varies substantially across healthcare facilities. In our review of EHR systems at ten healthcare facilities, we identified six success factors which may be useful for healthcare organizations seeking to improve the quality of their problem list documentation: financial incentives, problem oriented charting, gap reporting, shared responsibility, links to billing codes, and organizational culture.

O objetivo deste trabalho foi comparar os efeitos sorológicos e clínicos de dois protocolos de terapias periodontais em indivíduos com diabetes tipo 2 (DMT2) e periodontite crônica. Foram analisados 36 pacientes, randomizados em dois grupos: um grupo recebeu terapia intensiva de raspagem e alisamento radicular (INT; n=18) e outro recebeu apenas raspagem supragengival (SUP; n=18). Os grupos foram avaliados quanto aos parâmetros clínicos periodontais e marcadores inflamatórios séricos, antes e após 6 meses do tratamento periodontal. O exame clínico periodontal avaliou: placa visível (IP), índice gengival (IG), supuração (SUPUR), profundidade clínica de sondagem (PCS) e nível clínico de inserção (NCI). Amostras sanguíneas foram obtidas para análise de marcadores inflamatórios e hemoglobina glicada (HbA1c). Os marcadores de inflamação avaliados foram: interleucina (IL)-1, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, fator estimulador de colônias granulocitárias (G-CSF), fator estimulador de colônias de granulócitos-macrófagos (GM-CSF), interferon- (IFN-), proteína quimiotática de monócito-1 (MCP-1), proteína inflamatória de macrófago-1 (MIP-1) e fator de necrose tumoral (TNF-), através do imunoensaio multiplex (Bioplex). Ambas as terapias resultaram na melhora de quase todos os parâmetros clínicos periodontais (p<0,05), com exceção do NCI (p=0,09) no grupo SUP. Não houve diferença significativa para os níveis de IL-1, IL-4, IL-5, IL-10, IL-13, MIP-1 e TNF- (p>0,05), após tratamento, em ambas as terapias. Houve redução significativa de IL-6 (p=0,01), IL-12 (p=0,04) e MCP-1 (p=0,02) no grupo INT e de GCS-F nos grupos SUP (p=0,04) e INT (p=0,01). Os níveis de IL-2, IL-7, IL-8, IL-17, GM-CSF e IFN- não foram detectados. A terapia INT tem um efeito benéfico na redução dos níveis séricos de IL-6, IL-12 e MCP-1, na redução de PCS em sítios profundos e no ganho de inserção quando comparado à terapia supragengival em um período de 6 meses...
The objective of this study was to compare the serological and clinical effects of two periodontal therapies in individuals with type 2 diabetes (T2DM) and chronic periodontitis. 36 patients were analyzed, randomized into two groups: one group received intensive t of scaling and root planing (INT, n=18) and another received only supragingival scaling (SUP, n=18). The groups were evaluated for periodontal parameters and serum inflammatory markers before and after 6 months of periodontal treatment. The periodontal parameters assessed were: visible plaque (PI), gingival index (GI), suppuration (SUP), probing pocket depth (PPD) and clinical attachment level (CAL). Blood samples were obtained for analysis of inflammatory markers and glycated hemoglobin (HbA1c). The inflammatory markers evaluated were: interleukin (IL)- 1 , IL- 2, IL -4, IL -5, IL -6, IL -7 , IL-8 , IL-10 , IL-12 , IL-13 , IL -17, granulocyte colony-stimulated factor (G -CSF), colony stimulating factor granulocyte-macrophage (GM -CSF), interferon - (IFN - ), monocyte chemotactic protein-1 (MCP-1) , macrophage inflammatory protein-1 (MIP-1 ) and tumor necrosis factor (TNF- ) through a multiplex immunoassay (Bioplex). Both therapies resulted in improvement of almost all periodontal clinical parameters (p<0.05), with the exception of the NCI in SUP group. There was no significant difference for (IL )- 1 , IL- 4, IL -5, IL-10 , IL-13 , MIP- 1 and TNF- after treatment for both therapies (p>0.05). A significant reduction was observed in IL-6 (p=0.01), IL-12 (p=0.04) and MCP-1 (p=0.02) levels for INT group and in GCS- F levels for SUP (p=0.04) and INT (p=0.01) groups. The levels of IL-2, IL -7, IL-8 , IL-17, GM- CSF and IFN- were not detectable. The INT therapy has a beneficial effect in reducing serum levels of IL-6, IL-12 and MCP-1, in reducing PPD of deep sites and in attachment gain when compared to SUP therapy considering a period of 6 months...

Mulberry leaves (Morus alba L.) are a traditional Chinese medicine for blood serum glucose reduction. This study evaluated the protective effects of mulberry flavonoids on sciatic nerve in alloxan-induced diabetic rats. In this study, 80 Sprague-Dawley rats were divided into five groups: A (control), B (diabetic treated with saline), C-D (diabetic treated with 0.3, 0.1 g/kg mulberry flavonoids once a day for 8 weeks) and E (diabetic treated with 0.3 mg/kg methycobal). The diabetic condition was induced by intraperitoneal injection of 200 mg/kg alloxan dissolved in saline. At the end of the experimental period, blood, and tissue samples were obtained for biochemical and histopathological investigation. Treatment with 0.3 g/kg mulberry flavonoids significantly inhibited the elevated serum glucose (P< 0.01). The increased myelin sheath area (P< 0.01), myelinated fiber cross-sectional area and extramedullary fiber number (P< 0.05) were also reduced in alloxan-induced rats treated with 0.3 g/kg mulberry flavonoids. 0.3 g/kg mulberry flavonoids also markedly decreased onion-bulb type myelin destruction and degenerative changes of mitochondria and Schwann cells. These findings demonstrate that mulberry flavonoids may improve the recovery of a severe peripheral nerve injury in alloxan-induced diabetic rats and is likely to be useful as a potential treatment on peripheral neuropathy (PN) in diabetic rats.
Folhas de amoreira (Morus alba L.) é um medicamento tradicional chinês para a redução da glicose no soro sanguíneo. Avaliaram-se, neste trabalho, os efeitos protetores dos flavonóides de amora no nervo ciático em ratos diabéticos aloxano-induzidos. Dividiram-se 80 ratos Sprague-Dawley em cinco grupos: A (controle), B (diabétidos tratados com solução salina), C-D (diabéticos tratados com 0,3, 0,1 g/kg) e E (diabéticos tratados com 0,3 mg de metilcobal).A diabetes foi induzida por injeção intraperitoneal de 200 mg/kg de aloxana dissolvida em solução salina. No final do período experimental, obtiveram-se amostras de sangue e de tecido para investigação bioquímica e histopatológica. O tratamento com 0,3 g/kg de flavonóides da amoreira inibiu, significativamente, a elevação de glicose no soro (p <0,01). O aumento da área da bainha de mielina (p <0,01), da área de fibra da seção transversal e do número de fibras mielinizadas extramedulares (p <0,05) foi também reduzido em ratos aloxânicos, tratados com 0,3 g/kg flavonóides de amora. Flavonóides da amoreira na dose de 0,3 g/kg também diminuiram, acentuadamente, a destruição da mielina do tipo bulbo de cebola e as alterações degenerativas das células mitocôndrias e das células de Schwann. Estes resultados demonstram que os flavonóides da amoreira podem melhorar a recuperação de uma lesão nervosa periférica grave em ratos com diabetes, induzida por aloxana, e parece ser útil como tratamento potencial para a neuropatia periférica (PN) em ratos diabéticos.
