Hiperglicemia y diabetes inducidas por esteroides / Hyperglycemia and steroid-induced diabetes

La hiperglicemia y/o diabetes inducida por esteroides, se define como la elevación de la glicemia, causada por la acción de los fármacos glucocorticoideos, sobre el metabolismo de los carbohidratos, y presenta una prevalencia entre un 20% al 50%, en pacientes sin diabetes previa, existiendo mayor riesgo para esta patología en pacientes con diabetes pre-existente, obesidad, uso crónico de esteroides o en dosis altas, entre otros. El diagnóstico se rige por los criterios para diabetes en la mayoría de los casos. No obstante, existen casos en donde la hiperglicemia por esteroides es sub-diagnosticada. Su manejo se basa en el tratamiento farmacológico (antidiabéticos orales, subcutáneos e insulina) y no farmacológico (dieta y ejercicio), tomando en cuenta, el patrón glicémico, peso, edad, co-morbilidades, dosis, tipo y tiempo de uso de los esteroides. La relevancia de conocer como diagnosticar y tratar dicha patología, se debe al riesgo de ingreso hospitalario, de infección, de mala cicatrización y de mortalidad en casos no tratados. En vista del aumento del uso de glucocorticoides en la actualidad, se hace una revisión del abordaje terapéutico de la hiperglicemia y diabetes inducida por esteroides.

Hyperglycemia and Steroid-induced Diabetes is defined as the elevation of glycemia caused by the action of glucocorticoid drugs on carbohydrate metabolism, with a prevalence between 20% and 50% in patients without Diabetes. Though, there is a greater risk of this pathology in patients with pre-existing Diabetes, Obesity, chronic use of steroids or in high doses, among others. In most cases, the diagnosis is governed by the criteria of Diabetes; however, there are cases where hyperglycemia Steroid-induced is under-diagnosed. Its management is based on pharmacological treatment (oral and subcutaneous hypoglycemic agents and insulin) and non-pharmacological treatment (diet and exercise), in accordance with the glycemic pattern, weight, age, co-morbidities, dose, type and the duration of the use of steroid. The relevance of knowing how to diagnose and treat this pathology is the risk of hospital admission, infection, poor healing and mortality in untreated cases. In view of the increased use of glucocorticoids nowadays, a review is made about the therapeutic approach to hyperglycemia and steroid-induced Diabetes.

Does Tight Glucose Control During the First 24 hours of Hospitalization Reduce Scintigraphic Infarct Size in STEMI Patients?

Abstract Background Hyperglycemia at the time of admission is related to increased mortality and poor prognosis in patients diagnosed with ST-segment elevation myocardial infarction (STEMI). Objective We aimed to investigate whether tight glucose control during the first 24 hours of STEMI decreases the scintigraphic infarct size. Methods The study population consisted of 56 out of 134 consecutive patients hospitalized with STEMI in a coronary care unit. Twenty-eight patients were treated with continuous insulin infusion during the first 24 hours of hospitalization, while the other 28 patients were treated with subcutaneous insulin on an as-needed basis. The final infarct size was evaluated with single-photon emission computed tomography (SPECT) in all patients on days 4 to 10 of hospitalization. The groups were compared and then predictors of final infarct size were analyzed with univariate and multivariate linear regression analysis. A p-value < 0.05 was considered statistically significant. Results The mean glucose level in the first 24 hours was 130 ± 20 mg/dL in the infusion group and 152 ± 31 mg/dL in the standard care group (p = 0.002), while the mean final infarct size was 20 ± 12% and 27 ± 15% (p = 0.06), respectively. The multivariate linear regression analysis demonstrated that the mean 24-hour glucose level was an independent predictor of the final infarct size (beta 0.29, p = 0.026). Conclusion Tight glucose control with continuous insulin infusion was not associated with smaller infarct size when compared to standard care in STEMI patients.

Biochemical and Molecular Mechanisms of Glucose Uptake Stimulated by Physical Exercise in Insulin Resistance State: Role of Inflammation / Mecanismos Bioquímicos e Moleculares da Captação da Glicose Estimulada pelo Exercício Físico no Estado de Resistência à Insulina: Papel da Inflamação

Abstract Obesity associated with systemic inflammation induces insulin resistance (IR), with consequent chronic hyperglycemia. A series of reactions are involved in this process, including increased release of proinflammatory cytokines, and activation of c-Jun N-terminal kinase (JNK), nuclear factor-kappa B (NF-κB) and toll-like receptor 4 (TLR4) receptors. Among the therapeutic tools available nowadays, physical exercise (PE) has a known hypoglycemic effect explained by complex molecular mechanisms, including an increase in insulin receptor phosphorylation, in AMP-activated protein kinase (AMPK) activity, in the Ca2+/calmodulin-dependent protein kinase kinase (CaMKK) pathway, with subsequent activation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), Rac1, TBC1 domain family member 1 and 4 (TBC1D1 and TBC1D4), in addition to a variety of signaling molecules, such as GTPases, Rab and soluble N-ethylmaleimide-sensitive factor attached protein receptor (SNARE) proteins. These pathways promote greater translocation of GLUT4 and consequent glucose uptake by the skeletal muscle. Phosphoinositide-dependent kinase (PDK), atypical protein kinase C (aPKC) and some of its isoforms, such as PKC-iota/lambda also seem to play a fundamental role in the transport of glucose. In this sense, the association between autophagy and exercise has also demonstrated a relevant role in the uptake of muscle glucose. Insulin, in turn, uses a phosphoinositide 3-kinase (PI3K)-dependent mechanism, while exercise signal may be triggered by the release of calcium from the sarcoplasmic reticulum. The objective of this review is to describe the main molecular mechanisms of IR and the relationship between PE and glucose uptake.

Resumo A obesidade associada à inflamação sistêmica induz resistência à insulina (RI), com consequente hiperglicemia crônica. Este processo envolve o aumento na liberação de citocinas pró-inflamatórias, ativação da enzima c-Jun N-terminal cinase (JNK), do fator nuclear kappa-B (NF-κB) e dos receptores do tipo Toll 4 (TLR4). Dentre as ferramentas terapêuticas disponíveis, o exercício físico (EF) tem efeito hipoglicemiante conhecido, explicado por mecanismos moleculares complexos. Dentre eles, ocorre aumento na fosforilação do receptor da insulina, na atividade da proteína quinase ativada por AMP (AMPK), na via da proteína cinase cinase dependente de Ca+2/calmodulina (CaMKK), com posterior ativação do coativador-1α do receptor ativado por proliferador do peroxissoma (PGC-1α), proteínas Rac1, TBC1 membro das famílias de domínio 1 e 4 (TBC1D1 e TBC1D4), além de uma variedade de moléculas de sinalização, como as proteínas GTPases, Rab e proteína solúvel de fusão sensível a N-etil-maleimida (SNARE); estas vias promovem maior translocação de transportador de glicose do tipo 4 (GLUT4) e consequente captação de glicose pelo músculo esquelético. A cinase fosfatidilinositol-dependente (PDK), proteína quinase C atípica (aPKC) e algumas das suas isoformas, como a PKC-iota/lambda também parecem desempenhar papel fundamental no transporte de glicose. Nesse sentido, a associação entre autofagia e EF também tem demonstrado papel relevante na captação de glicose muscular. A insulina, por sua vez, utiliza um mecanismo dependente da fosfatidilinositol-3-quinase (PI3K), enquanto que o sinal do EF pode ter início mediante liberação de cálcio pelo retículo sarcoplasmático e concomitante ativação da AMPK. O objetivo desta revisão é descrever os principais mecanismos moleculares da RI e da relação entre o EF e a captação de glicose.

Hiperglicemia por sepsis: del mecanismo a la clínica / Sepsis hyperglycemia in the ICU: from the mechanism to the clinic

Stress hyperglycemia is frequently diagnosed in septic patients in critical care units (ICU) and it is associated with greater illness severity and higher morbimortality rates. In response to an acute injury, high levels of counterregulatory hormones such as glucocorticoids and catecholamines are released causing increased hepatic gluconeogenesis and insulin resistance. Furthermore, during sepsis, proinflammatory cytokines also participate in the pathogenesis of this phenomenon. Septic patients represent a subtype of the critical ill patients in the ICU: this metabolic disarrangement management strategies and insulin therapy recommendations had been inconsistent. In this article, we describe the pathophysiological mechanisms of stress hyperglycemia in critical patients including the action of hormones, inflammatory cytokines and tissue resistance to insulin. In addition, we analyzed the main published studies for the treatment of acute hyperglycemia in critical patients.

Gastroesophageal reflux disease in patients with long standing type 1 diabetes mellitus: utility of two self-report questionnaires in a multifactorial disease / Enfermedad por Reflujo Gastroesofágico en pacientes con Diabetes Mellitus tipo 1: utilidad de dos cuestionarios auto-aplicables

Abstract Background: Gastroesophageal pathologies are common and multifactorial in patients with type 1 diabetes (T1DM). The evaluation with endoscopy and 24 h pH esophageal monitoring is expensive and not always available in all medical centers, especially in developing countries so more cost-effective algorithms for diagnosis are required. Clinical questionnaires are easy to apply but its utility for gastroesophageal reflux disease screening in patients with long standing T1DM must be analyzed. Objective: To evaluate the utility of the FSSG and Carlsson-Dent (CDQ) questionnaires to detect the frequency of gastroesophageal reflux disease in patients with T1DM. Methods: Analytic cross-sectional study, included 54 randomly selected patients from the T1DM clinic in our hospital. Before their routine evaluation, were asked to answer FSSG and CDQ questionnaires, classifying them as positive with a score >8 or >4, respectively. we associated and compared the clinical and biochemical characteristics between patients with or without gastroesophageal reflux detected through questionnaires. Results: Median age was 29 years (22-35), 67% were female (median of 16 years from diagnosis). In 39% of the patients FSSG was positive, CDQ was positive in 28%. A total of 71% of patients were taking medications to treat non-specific gastric symptoms. The concordance between questionnaires was 65% (p: <0.001). Those patients with tobacco consumption as well as those with poor glycemic control were more likely to score positive in either questionnaire. Conclusions: Patients T1DM had a high prevalence of gastroesophageal reflux disease. In those patients FSSG questionnaire detected a higher number of patients in comparison with CDQ.

Resumen Introducción: Las patologías gastroesofágicas son comunes y multifactoriales en pacientes con diabetes tipo 1 (DM1). La evaluación por medio de panendoscopia y pHmetría es costosa y difícil de realizar en todos los centros de atención, por lo que se requieren algoritmos rentables para su diagnóstico. Existen cuestionarios sencillos y autoaplicables que pueden ser útiles para el diagnóstico de enfermedad por reflujo gastroesofágico en los pacientes con DM1. Objetivo: Evaluar la utilidad de los cuestionarios FSSG y Carlsson-Dent (CDQ) para detectar la enfermedad por reflujo gastroesofágico (ERGE) en pacientes con DM1. Métodos: Estudio transversal, se incluyeron 54 pacientes, elegidos al azar de la clínica de DMT1. Previo a la consulta, se les solicitó contestaran los cuestionarios FSSG y el CDQ, considerándose positivos para diagnóstico de ERGE los puntajes >8 y >4, respectivamente. Se analizaron y compararon las características bioquímicas y clínicas entre los pacientes con y sin síntomas de ERGE detectada por medio de los cuestionarios. Resultados: Los pacientes estudiados tenían edad de 29 años (22-35), 67% fueron mujeres, (mediana de diagnóstico de 16 años). El 39% de los pacientes tenían ERGE detectado mediante FSSG y 28% utilizando el cuestionario CDQ. El 71% de los pacientes reportó uso de medicamentos para reflujo. La concordancia entre ambos cuestionarios fue del 65% (p: <0.001). Pacientes que consumen tabaco y con descontrol glucémico, tenían más probabilidades de positividad en cualquier cuestionario. Conclusiones: Existe una alta prevalencia de ERGE en los pacientes con DM1. En esta población el cuestionario FSSG detectó a un mayor número de pacientes en comparación con el CDQ.

Effects of exercise and metformin on the prevention of glucose intolerance: a comparative study

We aimed to evaluate the effects of aerobic exercise training (4 days) and metformin exposure on acute glucose intolerance after dexamethasone treatment in rats. Forty-two adult male Wistar rats (8 weeks old) were divided randomly into four groups: sedentary control (SCT), sedentary dexamethasone-treated (SDX), training dexamethasone-treated (DPE), and dexamethasone and metformin treated group (DMT). Glucose tolerance tests and in situ liver perfusion were undertaken on fasting rats to obtain glucose profiles. The DPE group displayed a significant decrease in glucose values compared with the SDX group. Average glucose levels in the DPE group did not differ from those of the DMT group, so we suggest that exercise training corrects dexamethasone-induced glucose intolerance and improves glucose profiles in a similar manner to that observed with metformin. These data suggest that exercise may prevent the development of glucose intolerance induced by dexamethasone in rats to a similar magnitude to that observed after metformin treatment.

Glycemic control in cardiac surgery: Rationale and current evidence.

Studies in cardiac surgical patients have shown an association of hyperglycemia with increased incidences of sepsis, mediastinitis, prolonged mechanical ventilation, cardiac arrhythmias and longer intensive care and hospital stay. There is considerable controversy regarding appropriate glycemic management in these patients and in the defi nition of hyperglycemia and hypoglycemia or the blood sugar levels at which therapy should be initiated. There is also dilemma regarding the usage of “tight glycemic control” with studies showing confl icting evidences. Part of the controversy can be explained by the differing designs of these studies and the variable defi nitions of hyperglycemia and hypoglycemia.

Avaliação e tratamento da hiperglicemia em pacientes graves / Assessment and treatment of hyperglycemia in critically ill patients

A hiperglicemia é um problema frequentemente encontrado em pacientes graves em ambiente de terapia intensiva. Sua presença se associa ao aumento da morbidade e da mortalidade, independentemente da causa da admissão (infarto agudo do miocárdio, condição após cirurgia cardiovascular, acidente vascular cerebral e sepse). Entretanto, permanecem muitas dúvidas com relação à fisiopatologia e, particularmente, em relação ao tratamento da hiperglicemia no paciente graves. Na prática clínica, devem ser levados em consideração diversos aspectos para o controle desses pacientes, inclusive os alvos de glicemia, o histórico de diabetes mellitus, a via de nutrição (enteral ou parenteral) e o equipamento de monitoramento disponível, o que aumenta substancialmente a carga de trabalho dos profissionais envolvidos nesse tratamento. Esta revisão descreveu a epidemiologia, a fisiopatologia, o tratamento e o monitoramento da hiperglicemia no paciente adulto grave.

Hyperglycemia is a commonly encountered issue in critically ill patients in the intensive care setting. The presence of hyperglycemia is associated with increased morbidity and mortality, regardless of the reason for admission (e.g., acute myocardial infarction, status post-cardiovascular surgery, stroke, sepsis). However, the pathophysiology and, in particular, the treatment of hyperglycemia in the critically ill patient remain controversial. In clinical practice, several aspects must be taken into account in the management of these patients, including blood glucose targets, history of diabetes mellitus, the route of nutrition (enteral or parenteral), and available monitoring equipment, which substantially increases the workload of providers involved in the patients' care. This review describes the epidemiology, pathophysiology, management, and monitoring of hyperglycemia in the critically ill adult patient.

Respuestas metabólicas inducidas por ejercicio físico de alta intensidad en mujeres sedentarias con glicemia basal alterada e hipercolesterolemia / Metabolic response to high intensity exercise training in sedentary hyperglycemic and hypercholesterolemic women

Background: High intensity training could be an effective way of improving health on individuals at high metabolic risk. Aim: To investigate the effects of a high intensity training intervention on metabolic-related markers in sedentary women at high metabolic risk. Material and Methods: Forty six sedentary women with a body mass index (BMI) over 25 kg/m² were assigned to four groups, according to their metabolic profile; hyperglycemia (H, n = 12), hyperglycemia/hypercholesterolemia (HH, n = 13), normoglycemia (N, n = 10) and normoglycemia/hypercholesterolemia (NH, n = 11). For 12 weeks and five days per week, subjects performed seven intervals of high intensity training (20 to 30 seconds) during a training session of 20 minutes. Anthropometric (body weight, body mass index (BMI), waist circumference) and metabolic variables (glucose, total cholesterol, LDL, HDL and TG) were measured at baseline, at 6 and 12 weeks of intervention. Results: BMI and waist circumference decreased significantly after 12 weeks of intervention. Similarly, glucose decreased significantly after 12 weeks of intervention in all groups. The reduction was of higher magnitude in those groups with hyperglycemia (H = -16%, HH = -22%, N = -7,5%, NH = -9,6%). However, lipid profile (TG, total cholesterol, LDL and HDL) improved significantly only in the hypercholesterolemic groups. Conclusions: Physical activity programs incorporating high intensity training can improve glucose and lipid profile in women with metabolic disorders. Moreover, this benefit is greatest in those individuals with highest metabolic burden.

Estados hiper e hipoglicêmicos agudos: conduta atual / Acute hyper and hypoglycaemic states: current conduct

Os estados hiperglicêmicos e hipoglicêmicos agudos são exemplos das mais comuns emergências médicas com que nos deparamos no campo das alterações do metabolismo. Os estados hiperglicêmicos agudos compreendem a cetoacidose diabética e o coma hiperosmolar hiperglicêmico não cetótico. Neste artigo, analisamos essas condições hiperglicêmicas, que representam um desafio para o clínico e o médico generalista que trabalham no terreno nas emergências médicas

The acute hypoglycemic and hyperglycemic situations are examples of the most common medical emergencies that we face in the field of metabolic disorders. The acute hyperglycemic situations include diabetic ketoacidosis and hyperosmolar hyperglycemic coma hyperosmolar nonketotic. In this article, we analyze these two hyperglycemic conditions that represent a challenge to the clinician and general practitioner working in the field in medical emergencies

Benefits of early glycemic control by insulin on sensory neuropathy and cataract in diabetic rats.

While there is an emphasis on the early glycemic control for its long-term benefits in preventing microvascular complications of diabetes, the biochemical mechanisms responsible for the long-lasting effects are not clearly understood. Therefore the impact of early insulin (EI) versus late insulin (LI) treatment on diabetic sensory neuropathy and cataract in streptozotocin-induced diabetic Wistar male rats were evaluated. EI group received insulin (2.5 IU/animal, once daily) treatment from day 1 to 90 while LI group received insulin from day 60 to 90. Early insulin treatment significantly reduced the biochemical markers like glucose, triglyceride, glycated hemoglobin, thiobarbituric acid reactive substances, advanced glycation end products and ratio of reduced glutathione and oxidized glutathione in diabetic rats. The late insulin treatment failed to resist the biochemical changes in diabetic rats. Diabetic rats developed sensory neuropathy as evidenced by mechanical and thermal hyperalgesia and showed a higher incidence and severity of cataract as revealed by slit lamp examination. Early insulin treatment protected the rats from the development of neuropathy and cataract, but late insulin administration failed to do so. The results demonstrate the benefits of early glycemic control in preventing neuropathy and cataract development in diabetic rats.

Effect of ambulatory versus hospital treatment for gestational diabetes or hyperglycemia on infant mortality rates: a systematic review / Efeito do tratamento ambulatorial versus hospitalar de diabetes ou hiperglicemia gestacional nas taxas de mortalidade infantil: revisão sistemática

CONTEXT AND OBJECTIVE: Pregnancies complicated by diabetes are associated with increased neonatal and maternal complications. The most serious maternal complication is the risk of developing type 2 diabetes, 10-12 years after the delivery. For rigorous control over blood glucose, pregnant women are treated through ambulatory management or hospitalization. The aim of this study was to evaluate the effectiveness of ambulatory management versus hospitalization in pregnancies complicated by diabetes or hyperglycemia. DESIGN AND SETTING: Systematic review conducted in a public university hospital. METHODS: A systematic review of the literature was performed and the main electronic databases were searched. The date of the most recent search was September 4, 2011. Two authors independently selected relevant clinical trials, assessed their methodological quality and extracted data. RESULTS: Only three studies were selected, with small sample sizes. There was no statistically significance different between ambulatory management and hospitalization, regarding mortality in any of the subcategories analyzed: perinatal and neonatal deaths (relative risk [RR] 0.65; 95% confidential interval [CI]: 0.11 to 3.84; P = 0.63); neonatal deaths (RR 0.29; 95% CI: 0.01 to 6.07; P = 0.43); and infant deaths (RR 0.29; 95% CI: 0.01 to 6.07; P = 0.43). CONCLUSIONS: This review, based on studies with high or moderate risk of bias, showed that there was no statistically significant difference between ambulatory management and hospital care, regarding reduction of mortality rates in pregnancies complicated by diabetes or hyperglycemia. It also suggested that there is a need for further randomized controlled trials on this issue. .

Care cost for pregnant and parturient women with diabetes and mild hyperglycemia / Custo da assistência de gestantes e parturientes diabéticas e com hiperglicemia leve / Costo de la asistencia de gestantes y parturientas diabéticas y con hiperglicemia leve

OBJECTIVE: To compare inpatient and outpatient care costs for pregnant/parturient women with diabetes and mild hyperglycemia. METHODS: A prospective observational quantitative study was conducted in the Perinatal Diabetes Center in the city of Botucatu, Southeastern Brazil, between 2007 and 2008. Direct and indirect costs and disease-specific costs (medications and tests) were estimated. Thirty diet-treated pregnant women with diabetes were followed up on an outpatient basis, and 20 who required insulin therapy were hospitalized. RESULTS: The cost of diabetes disease (prenatal and delivery care) was US$ 3,311.84 for inpatients and US$ 1,366.04 for outpatients. CONCLUSIONS: Direct and indirect costs as well as total prenatal care cost were higher for diabetic inpatients while delivery care costs and delivery-postpartum hospitalization were similar. Prenatal and delivery-postpartum care costs were higher for these patients compared to those paid by Brazilian National Health System.

Cost-benefit of hospitalization compared with outpatient care for pregnant women with pregestational and gestational diabetes or with mild hyperglycemia, in Brazil / Custo-benefício da hospitalização comparada ao atendimento ambulatorial em gestantes com diabetes pré-gestacional e gestacional ou com hiperglicemia leve, no Brasil

CONTEXT AND OBJECTIVE: Pregnancies complicated by diabetes are associated with increased numbers of maternal and neonatal complications. Hospital costs increase according to the type of care provided. This study aimed to estimate the cost-benefit relationship and social profitability ratio of hospitalization, compared with outpatient care, for pregnant women with diabetes or mild hyperglycemia. STUDY DESIGN: This was a prospective observational quantitative study conducted at a university hospital. It included all pregnant women with pregestational or gestational diabetes, or mild hyperglycemia, who did not develop clinical intercurrences during pregnancy and who delivered at the Botucatu Medical School Hospital (Hospital das Clínicas, Faculdade de Medicina de Botucatu, HC-FMB) of Universidade Estadual de São Paulo (Unesp). METHODS: Thirty pregnant women treated with diet were followed as outpatients, and twenty treated with diet plus insulin were managed through frequent short hospitalizations. Direct costs (personnel, materials and tests) and indirect costs (general expenses) were ascertained from data in the patients' records and the hospital's absorption costing system. The cost-benefit was then calculated. RESULTS: Successful treatment of pregnant women with diabetes avoided expenditure of US$ 1,517.97 and US$ 1,127.43 for patients treated with inpatient and outpatient care, respectively. The cost-benefit of inpatient care was US$ 143,719.16, and outpatient care, US$ 253,267.22, with social profitability of 1.87 and 5.35, respectively. CONCLUSION: Decision-tree analysis confirmed that successful treatment avoided costs at the hospital. Cost-benefit analysis showed that outpatient management was economically more advantageous than hospitalization. The social profitability of both treatments was greater than one, thus demonstrating that both types of care for diabetic pregnant women had positive benefits.

CONTEXTO E OBJETIVO: Gestações complicadas pelo diabetes estão associadas com aumento de complicações maternas e neonatais. Os custos hospitalares aumentam de acordo com a assistência prestada. O objetivo foi calcular o custo-benefício e a taxa de rentabilidade social da hospitalização comparada ao atendimento ambulatorial em gestantes com diabetes ou com hiperglicemia leve. DESENHO DO ESTUDO: Estudo prospectivo, observacional, quantitativo, realizado em hospital universitário, sendo incluídas todas as gestantes com diabetes pregestacional e gestacional ou com hiperglicemia leve que não desenvolveram intercorrências clínicas na gestação e que tiveram parto no Hospital das Clínicas, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (HC-FMB-Unesp). MÉTODOS: Trinta gestantes tratadas com dieta foram acompanhadas em ambulatório e 20 tratadas com dieta e insulina foram abordadas com hospitalizações curtas e frequentes. Foram obtidos custos diretos (pessoal, material e exames) e indiretos (despesas gerais) a partir de dados contidos no prontuário e no sistema de custo por absorção do hospital e posteriormente calculado o custo-benefício. RESULTADOS: O sucesso do tratamento das gestantes diabéticas evitou o gasto de US$ 1.517,97 e US$ 1.127,43 para pacientes hospitalizadas e ambulatoriais, respectivamente. O custo-benefício da atenção hospitalizada foi US$ 143.719,16 e ambulatorial, US$ 253.267,22, com rentabilidade social 1,87 e 5,35 respectivamente. CONCLUSÃO: A análise "árvore de decisão" confirma que o sucesso dos tratamentos elimina custos no hospital. A relação custo-benefício indicou que o tratamento ambulatorial é economicamente mais vantajoso do que a hospitalização. A rentabilidade social de ambos os tratamentos foi maior que 1, indicando que ambos os tipos de atendimento à gestante diabética têm benefício positivo.

Electroacupuncture stimulation using different frequencies (10 and 100 Hz) changes the energy metabolism in induced hyperglycemic rats / Eletroacupuntura usando diferentes freqüências (10 e 100 Hz) altera o metabolismo energético em ratos hiperglicêmicos induzidos

PURPOSE: To investigate the effect of 10 and 100 Hz peripheral electro-estimulation (electroacupuncture, EAc) at Zusanli (ST-36) and Zhongwan (CV-12) acupoints on blood glucose and lactate levels and tissue (liver and kidney) concentrations of lactate in hyperglycemic induced anesthetized rats. METHODS: Thirty-six rats were randomly assigned to 3 groups (n=12): G1: basal (anesthesia: ketamine (90mg kg-1 body weight)+ xylazine (10mg/kg-1 body weight, i.p.); G2: anesthesia+EA10Hz EAc and G3: anesthesia+EA100Hz EAc). EAc stimulation was delivered for 30 min at 10 mA at selected acupoints. Blood and tissue (kidney, liver) samples were collected at the end of the EAc application (n=6, T30) and 30 minutes later (n=6, T60) for biochemical analysis. G1 samples were collected at the same timepoints. ANOVA followed by Tukey's Multiple Comparison Test was used for statistical analyses. RESULTS: Glycemia decreased significantly (p<0.001) in G2/G3 rats in all timepoints. Kidney and liver lactate concentrations decreased significantly (p>0.001) in G2/G3 rats at T-60 and at T30 timepoints in G2 compared with G1 rats. Lactacedemia decreased significantly at T30 timepoint in G2 compared with G1 rats. G1/G3 tissue lactate levels were not different. CONCLUSIONS: Electroacupuncture (10 Hz) applied to St-36 and CV-12 acupoints decreases glycemia and lactacedemia and liver and kidney lactate concentrations. We hypothesize that the decrease in lactate levels may be related to greater energy production due to enhanced lactate to pyruvate conversion. Higher frequency (100 Hz) failed to promote the same effect.

OBJETIVO: Investigar o efeito da eletroacupuntura (10-100 Hz) aplicada nos acupontos Zusanli (ST-36) e Zhongwan (CV-12) sobre a glicemia, lactacedemia e concentrações de lactato no fígado/rim em ratos anestesiados. MÉTODOS: Trinta e seis ratos foram distribuídos aleatoriamente em três grupos (n= 12): G1: basal (anestesia: cetamina (90mg kg-1)+xilazina (10mg/kg-1, ip), G2: anestesia+10Hz EAc e G3: anestesia+100Hz EAc). EAc foi aplicada por 30 min (10 mA) em acupontos selecionados. Amostras de sangue e tecidos (rim, fígado) foram coletadas no final da aplicação da EAc (n=6, T30) e 30 minutos depois (n=6, T60) para análise bioquímica. Amostras de G1 foram coletadas nos mesmos tempos (T30 e T60). ANOVA seguido pelo teste de comparações múltiplas de Tukey foi utilizado para análises estatísticas. RESULTADOS: A glicemia diminuiu significativamente (p<0,001) nos grupos G2/G3 em todos os pontos temporais. As concentrações de lactato nos rins e no fígado diminuiu significativamente (p<0,001) nos ratos G2/G3 ratos no T-60 e no T30 no G2, comparados com ratos G1. Lactacedemia diminuiu significativamente no T30 no G2 comparado com G1. Os níveis de lactato tecidual não foram diferentes comparando os grupos G1/G3. CONCLUSÕES: Eletroacupuntura (10 Hz) aplicada aos acupontos ST-36 e CV-12 reduz a glicemia e lactacedemia bem como as concentrações de lactato no fígado e nos rins. Nossa hipótese é que a diminuição dos níveis de lactato possa estar relacionada à maior produção de energia devido ao aumento de conversão de lactato para piruvato. A utilização de uma freqüência mais alta (100 Hz) não produz o mesmo efeito.

Hypoglycaemic and anti-diabetic activity of stem bark extracts Erythrina indica in normal and alloxan-induced diabetic rats

The objective of the study is to investigate the alcoholic [AlcE] and aqueous [AqsE] extracts of stem bark of Erythrina indica [Papilionaceae] for hypoglycaemic effects in normal and diabetic rats. Diabetes was induced in rats by a single dose administration of alloxan [120 mg/kg, i.p.] or by injecting dexamethasone [10 mg/kg, i.p.] for 10 days. In normal rats, AlcE and AqsE had significantly decreased the blood glucose level [BGL] in a dose dependent manner after repeated administration for 7 days. In alloxan-induced diabetic rats, both the extracts decreased blood sugar levels with significant improvement in glucose tolerance and body weight at the end of 1st, 2nd and 3rd week after test extract treatment. In case of dexamethasone induced insulin resistant diabetic rats, repeated administration of AlcE and AqsE inhibited the increase in blood glucose level and improved glucose tolerance induced by dexamethasone as compared to dexamethasone induced diabetic rats. These results suggest that both extracts possess hypoglycaemic activity in normal as well as in diabetic rats. Among AlcE and AqsE, AqsE possesses better hypoglycaemic activity than AlcE in all the models. Preliminary phytochemical investigations revealed that alcoholic extracts contain carbohydrates, alkaloids, flavonoids, saponins, phytosterols, phenolics and tannins. Aqueous extract contains carbohydrates, alkaloids, flavonoids, glycosides, phytosterols and triterpenoids. These phytoconstituents may be responsible for the hypoglycaemic activity of the plant

comparative study of efficacy of intensive insulin therapy versus conventional method on mortality and morbidity of critically ill patients

Hyperglycemia is associated with increased mortality and morbidity. Current evidence has controversies about Intensive Insulin Therapy [NT] and its effect on reducing mortality in critically ill patients. In this trial we evaluated the effect of intensive insulin therapy with a simple protocol versus traditional method on morbidity and mortality of critically ill patients who were admitted to surgical intensive care unit. Sixty adult patients admitted to surgical intensive care unit between Feb 2009 to Feb 2010 in Shohada Hospital, were enrolled in this study. Patients were randomly allocated to intensive insulin therapy group [with a target blood sugar of 80-120 mg/dl] and conventional group [received insulin if blood glucose was more than 200 mg/dl]. Study was continued through the ICU stay of all patients. Acute Kidney Injury, Renal Replacement Therapy, Bactremia and transfusion were less in intensive insulin therapy without significant difference compared to control group. Mortality also was not significant between two groups. Because of the consequences of hyperglycemia, NT might be considered in critically ill patients, but intermediate levels may be more safe and effective and remains the best practice in Intensive Care Units. Defining ICU capability is critical for implementing tight glycemic control and future multi center studies are needed to consider the effect of NT on mortality as an essential outcome

Management of diabetes mellitus in developing countries: the relevance of postprandial hyperglycaemia

The prevalence of diabetes mellitus is rising globally and its complications present an immense public health burden to all health economies world-wide. The objective of this review article is to present the relevance of postprandial hyperglycaemia in the management of diabetes, which should guide clinicians in developing countries. It will discuss the definition, epidemiology, pathophysiology, complications and treatment strategies for postprandial hyperglycaemia. Sources of Data/Study selection: The data search used in this review covered studies published from 1965-2008 obtained from recent international conferences, World Health reports, prevalence studies, hospital- based studies, registry reports, hospital statistics, government estimates, United Nations Resolution on diabetes, International Diabetes Federation Declarations and clinical practice guidelines. The MEDLINE database, the internet [e-medicine, medscape resource centre], World Health and International Diabetes Federation Monographs were used for data extraction. The global explosion of diabetes as a pandemic is well recognized as well as preventive measures and effective treatments. This current knowledge however is under-utilized because in practice only about a third of people living with diabetes achieve optimum targets for glycaemic control. Hyperglycaemia is the central disorder in diabetes mellitus. It has been shown in several studies that the development of complications of diabetes is directly due to prolonged exposure of the body cells to glucose. There is a lot of emphasis on monitoring and treatment of fasting hyperglycaemia in diabetics. Drugs which target postprandial hyperglycaemia are not widely in use in developing countries. It is hoped that this review will emphasize the need to use these drugs to the benefit of our patients

Nursing Interventions in the Clinical Practice of an Intensive Care Unit / Intervenções de enfermagem utilizadas na prática clínica de uma unidade de terapia intensiva / Intervenciones de enfermería utilizadas en la práctica clínica de una unidad de terapia intensiva

This cross-sectional study was carried out at a university hospital to describe the nursing interventions most frequently performed in the clinical practice of an intensive care unit, based on nursing care prescriptions, and to investigate their similarity to the Nursing Interventions Classification (NIC). The sample consisted of 991 hospitalizations of patients. Data were retrospectively collected from the computer database and analyzed through descriptive statistics and cross-mapping. A total of 57 different NIC interventions frequently used in the unit were identified; most of them in the complex (42 percent) and basic physiological (37 percent) domains, in the classes ‘respiratory management’ and ‘self-care facilitation’. Similarity between the nursing care prescribed and nursing interventions/NIC was found in 97.2 percent of the cases. The conclusion is that the interventions/NIC used in the clinical practice of this intensive care unit reflects the level of complexity of nursing care, which is mainly directed at the regulation of the body’s physical and homeostatic functioning.

Este é estudo descritivo, transversal, realizado em um hospital universitário com os objetivos de descrever as intervenções de enfermagem mais utilizadas na prática clínica de uma unidade de terapia intensiva, com base nas prescrições de enfermagem, e analisar a sua similaridade com a Nursing Interventions Classification (NIC). A amostra constou de 991 internações de pacientes. Os dados foram coletados, retrospectivamente, em base informatizada, e analisados pela estatística descritiva e mapeamento cruzado. Identificaram-se 57 diferentes intervenções/NIC, frequentemente utilizadas na unidade, sendo a maioria no domínio fisiológico complexo (42 por cento) e fisiológico básico (37 por cento), nas classes de controle respiratório e facilitação do autocuidado. Em 97,2 por cento dos casos houve similaridade entre as prescrições de enfermagem da unidade e as intervenções/NIC. Conclui-se que as intervenções/NIC, utilizadas na prática clínica da unidade de terapia intensiva, refletem o nível de complexidade do cuidado de enfermagem nessa unidade, destinando-se, principalmente, à regulação do funcionamento físico e homeostático do organismo.
