Introducción. La hipoglucemia neonatal es una complicación de la diabetes mellitus gestacional Son pocos los estudios que avalan la pesquisa sistemática en este grupo poblacional durante las primeras horas de vida. Objetivos. Evaluar la asociación entre tratamiento materno recibido (dieta versus insulina) y el desarrollo de hipoglucemia, e identificar los factores de riesgo asociados. Población y métodos. Estudio observacional, analítico y retrospectivo realizado en en las sedes de Buenos AIres y San Justo de un hospital general de tercer nivel entre el 1 de enero de 2017 y el 31 de diciembre de 2018. Se estimó la incidencia de hipoglucemia (≤47 mg/dl) en recién nacidos según el manejo de la diabetes materna y se realizó un análisis multivariable para evaluar factores asociados. Resultados. Se incluyeron 195 pacientes. No se encontró diferencia estadística en la incidencia de hipoglucemia según el tratamiento materno recibido (45,3 % versus 39,7 %; p = 0,45) ni se identificaron factores de riesgo asociados. Modificando el valor de corte a ≤40 mg/dl, tampoco se encontraron diferencias en la incidencia (23,4 % versus 19 %, p = 0,48); no obstante, los pacientes hipoglucémicos presentaron un hematocrito significativamente mayor y una menor prevalencia de lactancia exclusiva al egreso. El análisis multivariable mostró una asociación independiente entre alto peso al nacer con hipoglucemia que requiere corrección. Conclusiones. La incidencia de hipoglucemia neonatal en la población estudiada no presentó diferencia según el tratamiento materno recibido. El estudio realizado fundamenta el control de la glucemia en estos niños en la práctica diaria.
Introduction. Neonatal hypoglycemia is a complication of gestational diabetes mellitus. Few studies have been conducted to support a systematic screening in the first hours of life of this population group. Objectives. To assess the association between the treatment administered to the mother (diet vs. insulin) and the development of hypoglycemia, and to identify associated risk factors. Population and methods. Observational, analytical, and retrospective study carried out at the Buenos Aires and San Justo maternal centers of a general, tertiary care hospital between 01-01-2017 and 12-31-2018. The incidence of neonatal hypoglycemia (≤ 47 mg/dL) based on the management of maternal diabetes was estimated and a multivariate analysis was done to assess related factors. Results. A total of 195 patients were included. No statistical difference was found in the incidence of hypoglycemia based on the treatment administered to the mother (45.3% vs. 39.7%; p = 0.45) and no associated risk factors were identified. Once the cutoff point was changed to ≤ 40 mg/dL, no differences were found in the incidence either (23.4% versus 19%, p = 0.48); however, patients with hypoglycemia had a significantly higher hematocrit level and a lower prevalence of exclusive breastfeeding upon discharge. Multivariate analysis showed an independent association between a high birth weight and hypoglycemia, requiring correction. Conclusions. The incidence of neonatal hypoglycemia in the studied population did not vary based on the treatment received by the mother. This study supports the control of glycemia in these infants in daily practice.

Social vulnerability has proved to be an independent risk factor for hypoglycemia in patients with diabetes. In some countries, patients who are in a vulnerable situation are assisted in the public health system which provides free medical care. This study compares the prevalence of hypoglycemia among patients with type 2 diabetes (T2D), in public versus private sector and its relationship with social vulnerability. This multicentric descriptive study included 600 patients with T2D from public and private care institutions of Argentina. Socioeconomic level (SEL) was evaluated through the Marketing Argentinean Association survey. Number of severe, documented symptomatic and asymptomatic hypoglycemias were registered. Among the patients included, 66% were assisted in the public sector. The 41% of patients (n = 246) registered at least 1 episode of any hypoglycemia event being more prevalent in the public sector compared to the private sector (50% vs. 22%). In the adjusted analysis it was observed a greater risk of hypoglycemia in public sector (OR 4, 95% CI 2.65-6.04) and in patients that did not have diabetological education (OR 2.28 95% CI 1.35-3.84). Similarly, unemployment (OR 5.04 95% CI 2.69-9.46), and marginal SEL (OR 60.79 95% CI 14.89-248.13) increased the risk of hypoglycemia. Several factors related to social vulnerability as unemployment, marginal SEL and poor sanitary education showed a significant increase in the hypoglycemia risk. Professionals working with people with diabetes must take into account these factors for a safe treatment of the disease.
La vulnerabilidad social ha demostrado ser un factor de riesgo independiente de hipoglucemia en pacientes con diabetes. Los pacientes que se encuentran en situación de vulnerabilidad social reciben asistencia en el sistema de salud pública que brinda atención médica gratuita. Este estudio compara la prevalencia de hipoglucemia en pacientes con diabetes tipo 2 en el sector público frente al privado y su relación con la vulnerabilidad social. Se realizó un estudio multicéntrico descriptivo que incluyó 600 pacientes con diabetes tipo 2 de instituciones de atención pública y privada de Córdoba. El nivel socioeconómico se evaluó a través de la encuesta de la Asociación Argentina de Marketing que evalúa la dimensión social, educativa y económica para estratificar el nivel socioeconómico. Se registró el número de hipoglucemias graves, documentadas sintomáticas y asintomáticas. El 66% de los pacientes pertenecían al sector público. El 41% de los pacientes (n = 246) registró al menos 1 episodio de cualquier evento de hipoglucemia. En el análisis ajustado, se observó un mayor riesgo de hipoglucemia en el sector público (OR 4, 95% CI 2.65-6.04), en pacientes que no tenían educación diabetológica previa (OR 2.28, 95% CI 1.35-3.84), en desempleados (OR 5.04, 95% CI 2.69-9.46) y en aquellos con nivel socioeconómico marginal (OR 60.79 95% CI 14.89-248.13). Factores relacionados con la vulnerabilidad social como el desempleo, el nivel socioeconómico marginal y educación sanitaria deficiente mostraron un aumento en el riesgo de hipoglucemia. Los profesionales que trabajan con personas con diabetes deben tener en cuenta estos factores para un tratamiento seguro de la enfermedad.

ABSTRACT Objective: To evaluate serum biochemical parameters' evolution, especially venous blood gas (VBG), in anorexia nervosa (AN), correlating with clinical parameters. Methods: Retrospective study including out-patient AN adolescents, between January 2014 and May 2017. Three evaluations were compared: t1) first consultation; t2) consultation with the lowest body mass index (BMI) z-score and t3) with the highest BMI z-score. Results: A total of 24 adolescents (87.5% females) were included, mean age of presentation of 14.9±1.7 years, onset of symptoms 6.4±3.2 months before the first visit. In t1, BMI z-score of -1.91±1.11 kg/m2 and ideal weight % of 84.3±9.2. Amenorrhea was present in 88%. In t2 the analytical alterations were: altered VBG in 100%, altered ferritin (72% elevated), altered thyroid function (53% with thyroxine decrease), dyslipidemia (31% elevation of high density lipoprotein, 25% hypercholesterolemia), elevation of urea (25%), elevation of alanine aminotransferase (14%), hypoglycemia (14%), anemia (9%). Respiratory acidosis was present in 91% in t1, 100% in t2 and 94% in t3. There was a significant decrease between t2 and t3 in mean pCO2 (57.2 versus 53.6 mmHg; p=0.009) and mean HCO3 (30.0 versus 28.8 mEq/L; p=0.023). Conclusions: Respiratory acidosis and increased ferritin were common in this group. Respiratory acidosis was the most frequent abnormality with significant pCO2 and HCO3 variation in the recovery phase. VBG should be considered in AN evaluation, once it seems to be important in assessing the severity of the disease and its subsequent follow-up.
RESUMO Objetivo: Avaliar a evolução laboratorial, particularmente da gasometria venosa, na anorexia nervosa (AN), correlacionando os achados com parâmetros clínicos. Métodos: Estudo retrospetivo com adolescentes com AN seguidos em ambulatório, entre janeiro de 2014 e maio de 2017. Foram comparadas três avaliações: (t1) primeira consulta; (t2) consulta com escore Z de índice de massa corpórea (IMC) mais baixo; e (t3) consulta com escore Z de IMC mais elevado. Resultados: Incluídos 24 adolescentes, 87,5% do sexo feminino, idade média de apresentação de 14,9±1,7 anos, início dos sintomas 6,4±3,2 meses antes da primeira consulta. Em t1, escore Z de IMC de -1,91±1,11 kg/m2 e % de peso ideal de 84,3±9,2. Tinham amenorreia 88%. Em t2 as alterações laboratoriais encontradas foram: gasometria venosa alterada em 100%, ferritina alterada (72% elevada), função tiroideia alterada (53% com diminuição da tiroxina), dislipidemia (31% com elevação de lipoproteína de alta densidade, 25% com hipercolesterolemia), elevação da ureia (25%), elevação da alanina aminotransferase (14%), hipoglicemia (14%) e anemia (9%). A acidose respiratória esteve presente em 91% em t1, 100% em t2 e 94% em t3. Verificou-se diminuição significativa entre t2 e t3 da pressão parcial de CO2 (pCO2) média (57,2 versus 53,6 mmHg; p=0,009) e HCO3 médio (30,0 versus 28,8 mEq/L; p=0,023). Conclusões: A acidose respiratória e o aumento da ferritina foram comuns nesse grupo. Acidose respiratória foi a alteração mais frequente, com variação significativa de pCO2 e HCO3 na fase de recuperação. A gasometria venosa deve ser considerada na avaliação laboratorial na AN, pois parece ser importante na avaliação da gravidade e monitorização da doença.

Abstract Introduction: The non-interventional International Operations Hypoglycemia Assessment Tool (IO-HAT) study assessed the incidence of hypoglycemia in patients with insulin-treated diabetes across nine countries, including a cohort of patients in Colombia. Materials and methods: Hypoglycemia incidence among patients with insulin-treated diabetes was assessed across 26 sites in Colombia. Hypoglycaemic events (any, nocturnal or severe) were reported in self-assessment questionnaires (SAQ) and patient diaries based on capillary blood glucose measurement or symptoms. Retrospective events (severe events 6 months before baseline and any event 4 weeks before baseline) were recorded in SAQ, Part 1, and prospective events (4 weeks from baseline) were recorded in SAQ, Part 2, and patient diaries. Differences in hypoglycemia incidence reported in the retrospective and prospective periods were assessed using two-sided tests. Results: Of the 664 patients assessed, 213 had type 1 diabetes (T1D) and 451 had type 2 diabetes (T2D). Nearly all patients experienced at least one hypoglycaemic event in the prospective period (97.1% T1D; 93.3% T2D). Rates of hypoglycemia (events per person- year, PPY) were higher prospectively than retrospectively for any hypoglycemia (T1 D: 121.6 vs. 83.2, p<0.001; T2D: 28.1 vs. 24.6, p=0.127) and severe hypoglycemia (T 1D: 15.3 vs. 9.2, p=0.605; T 2 D: 9.5 vs. 3.5 p=0.040). Conclusion: These results, the first from a patient-reported dataset on hypoglycemia in insulin-treated patients with diabetes in Colombia, show that patients reported higher rates of any hypoglycemia during the prospective period.
Resumen Introducción. En el estudio no intervencionista International Operations Hypoglycemia Assessment Tool (IO-HAT), se evalúo la incidencia de hipoglucemia en pacientes diabéticos tratados con insulina en nueve países, incluido Colombia. Materiales y métodos. La incidencia de hipoglucemia entre pacientes diabéticos tratados con insulina se evaluó en 26 centros médicos en Colombia. Los episodios de hipoglucemia determinados con base en la medición de la glucemia capilar o en los síntomas se reportaron en el cuestionario de autoevaluación (Self-Assessment Questionnaire, SAQ) y en el diario del paciente. Los episodios retrospectivos (episodios graves y cualquiera ocurrido 6 meses y 4 semanas antes del inicio del estudio, respectivamente) se registraron en el SAQ, parte 1, y los eventos prospectivos (4 semanas desde el inicio), en el SAQ, parte 2, y en el diario del paciente. Las diferencias en la incidencia de la hipoglucemia entre los períodos retrospectivo y prospectivo se evaluaron mediante una prueba de dos colas. Resultados. De los 664 pacientes evaluados, 213 tenían diabetes de tipo 1 y 451 tenían diabetes de tipo 2. Casi todos los pacientes experimentaron al menos un episodio de hipoglucemia en el período prospectivo (97,1 %, diabetes de tipo 1, y 93,3 %, diabetes de tipo 2). Los índices de hipoglucemia (episodios año-persona) fueron mayores prospectivamente que retrospectivamente para cualquier tipo de hipoglucemia (diabetes de tipo 1: 121,6 Vs. 83,2; p<0,001; la diabetes de tipo 2: 28,1 Vs. 24,6; p=0,127) y para la hipoglucemia grave (diabetes de tipo 1: 15,3 Vs. 9,2; p=0,605; diabetes de tipo 2: 9,5 Vs. 3,5; p=0,040). Conclusión. Estos resultados, que constituyen el primer conjunto de datos sobre hipoglucemia informados por pacientes diabéticos colombianos tratados con insulina, evidenciaron tasas más altas para ambos tipos de hipoglucemia durante el período prospectivo.

Background: Hypoglycemia is a common metabolic problem encountered in pediatric emergency admissions. The absence of clinical symptoms does not preclude the presence of hypoglycemia as presentation may vary from asymptomatic to central nervous system and cardiopulmonary disturbances. If untreated, hypoglycemia can result in permanent neurological damage or even death. Objectives: The objective of the study is to determine the prevalence, associated factors and outcome of hypoglycemia in pediatric emergency admissions at Ahmad Sani Yariman Bakura Specialist Hospital, Gusau, Nigeria. Materials and Methods: The study was a prospective crosssectional study involving children aged 1 month13 years. Blood glucose was determined at admission using AccuChek® Active Blood Glucose Meter, and hypoglycemia was defined as blood glucose levels <2.8 mmol/L (<50 mg/dL). Age of the patients, sex, interval of last meal, presenting complaints diagnoses were recorded. Results: A total of 154 children were studied.Thirty (19.5%) were infants and 71 (46.1%) were underfives. Eightyseven (56.5%) were males with male to female ratio of 1.3:1.The prevalence of hypoglycemia was 22.1%. The predominant disease conditions the children with hypoglycemia presented with were severe malaria, acute diarrheal disease, and sepsis. The prevalence of hypoglycemia was significantly higher among children whose last meal was 8 h and above before presentation (42.9%). Children who presented with hypoglycemia were significantly more likely to die (odds ratio [OR] =13.3; 95% confidence interval [CI] =4.638.7). Among those with hypoglycemia, males were significantly more likely to die (OR = 4.2, 95% CI = 1.018.0). Hypoglycemia was significantly associated with mortality in children with severe malaria and pneumonia (P = 0.04 and 0.01, respectively). Conclusion: The prevalence of hypoglycemia is still high in our emergency admissions. It is associated with significant mortality especially among male children and those presenting with severe malaria and pneumonia. We recommend that hypoglycemia sought for and promptly treated in children presenting to emergency to reduce mortality

RESUMO Objetivos: Analisar a associação entre os níveis glicêmicos quando da admissão dos pacientes à unidade de terapia intensiva pediátrica e a mortalidade entre pacientes hospitalizados. Métodos: Estudo retrospectivo de coorte conduzido em pacientes de uma unidade de terapia intensiva, admitidos ao Instituto Nacional de Salud del Niño entre 2012 e 2013. Utilizou-se um modelo de regressão de Poisson com variância robusta para qualificar a associação. Foi feita avaliação do desempenho do exame diagnóstico, para descrever sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e razão de verossimilhança para cada faixa de glicemia. Resultados: Incluíram-se no total 552 pacientes (idade mediana de 23 meses; faixa de variação entre 5 meses e 79,8 meses). O nível glicêmico médio quando da admissão foi de 121,3mg/dL (6,73mmol/L). Faleceram durante a hospitalização 92 (16,6%) pacientes. Na análise multivariada, encontraram-se associações significantes entre glicemia < 65mg/dL (3,61mmol/L) (RR: 2,01; IC95% 1,14 - 3,53), glicemia > 200mg/dL (> 11,1mmol/L) (RR: 2,91; IC95% 1,71 - 4,55), desnutrição (RR: 1,53, IC95% 1,04 - 2,25), ventilação mecânica (RR: 3,71, IC95% 1,17 - 11,76) e mortalidade durante a hospitalização. Ocorreram baixa sensibilidade (entre 17,39% e 39,13%) e alta especificidade (entre 49,13% e 91,74%) para diferentes níveis glicêmicos de corte. Conclusão: Ocorreu maior risco de óbito entre os pacientes que desenvolveram hipoglicemia e hiperglicemia por ocasião da admissão à unidade de terapia intensiva pediátrica. Certas faixas de glicemia (> 200mg/dL (> 11,1mmol/L) e < 65mg/dL (3,61mmol/L)) tiveram uma alta especificidade como preditores de óbito.
ABSTRACT Objectives: To analyze the association between glycemia levels upon pediatric intensive care unit admission and mortality in patients hospitalized. Methods: A retrospective cohort of pediatric intensive care unit patients admitted to the Instituto Nacional de Salud del Niño between 2012 and 2013. A Poisson regression model with robust variance was used to quantify the association. Diagnostic test performance evaluation was used to describe the sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratios for each range of glycemia. Results: In total, 552 patients were included (median age 23 months, age range 5 months to 79.8 months). The mean glycemia level upon admission was 121.3mg/dL (6.73mmol/L). Ninety-two (16.6%) patients died during hospitalization. In multivariable analyses, significant associations were found between glycemia < 65mg/dL (3.61mmol/L) (RR: 2.01, 95%CI 1.14 - 3.53), glycemia > 200mg/dL (> 11.1mmol/L) (RR: 2.91, 95%CI 1.71 - 4.55), malnutrition (RR: 1.53, 95%CI 1.04 - 2.25), mechanical ventilation (RR: 3.71, 95%CI 1.17 - 11.76) and mortality at discharge. There was low sensitivity (between 17.39% and 39.13%) and high specificity (between 49.13% and 91.74%) for different glucose cut-off levels. Conclusion: There was an increased risk of death at discharge in patients who developed hypoglycemia and hyperglycemia upon admission to the pediatric intensive care unit. Certain glucose ranges (> 200mg/dL (> 11.1mmol/L) and < 65mg/dL (3.61mmol/L)) have high specificity as predictors of death at discharge.

Resumen Introducción: El bajo peso neonatal (< 2.5 kg o < percentil 10) se atribuye a causas constitucionales (pequeño para la edad gestacional [PEG]) o a la restricción en el crecimiento intrauterino (RCIU), con riesgos posnatales diferentes. En ausencia de una valoración fetal-placentaria prenatal adecuada, resulta difícil establecerlo. El conocer los antecedentes maternos de enfermedades gestacionales (AMEG): hipertensión arterial (HTA), hipotiroidismo, Diabetes Mellitus (DM) gestacional y otra; pudiera orientar a la diferenciación y el manejo. El objetivo de este trabajo fue determinar si la presencia de AMEG se asocia a complicaciones neonatales en productos de bajo peso neonatal. Métodos: Se realizó un estudio de cohorte retrospectivo en un grupo de 349 recién nacidos vivos de término (≥ 37 semanas de edad gestacional [SEG]), PEG, en cunero fisiológico y agrupados según los AMEG. Se determinó la frecuencia de dificultad respiratoria (DR), hipoglucemia (HG) e hiperbilirrubinemia (HBr). Resultados: El 16.6% (58/349) presentó AMEG (58.6% HTA y 41.3% hipotiroidismo, solos o combinados). Los neonatos con AMEG fueron más limítrofes (37 SEG, 55.2% vs. 35.1%; p = 0.037). Los de 37 SEG con menor peso (diferencia de ≈100 g; p = 0.028), más riesgo de HG (13.6%; intervalo de confianza al 95% [IC 95%]: −4.08-31.2) pero menos DR (diferencia de −4.7%; IC 95%: −20.6-11.05). La HG en los de 39 SEG solo se presentó en neonatos sin AMEG (diferencia 12.7%; IC 95%: 3.9 a 31.5) igual que la HBr (tres casos). Conclusiones: Indagar sobre los AMEG en un producto PEG parece ser útil en la inferencia de RCIU. Sin embargo, es insuficiente, por lo que en conjunto con otras herramientas nos ayuda a estimar posibles complicaciones y acciones preventivas.
Abstract Background: Low-birth-weight (LWB < 2.5 kg or <10 percentile) could be caused by constitutional matters or by intrauterine growth restriction (IUGR), both with different neonatal complications. Without an adequate prenatal evaluation is hard to stablish those conditions. Knowing the maternal history for gestational diseases (MHGD) such as hypertension (HTA), hypothyroidism or diabetes, among others could help clarify that difference. The aim of this work was to determine if having a MHGD is associated to neonatal complications in newborns with LWB. Methods: Retrospective cohort study, which included 349 with LWB at term (≥ 37 weeks of gestation [WG]) grouped into those with or without MHGD at a hospital nursery. The frequency of respiratory distress, hypoglycemia, and hyperbilirubinemia was determined. Results: 16.6% (58/349) had MHGD (58.6% for HTA and 41.3% hypothyroidism alone or combined). The neonate with MHGD were more borderline term (37 WGA, 55.2% vs. 35.1%; p = 0.037), and had lower weight (difference of ≈100 g; p = 0.028), had more cases with hypoglycemia (13.6%; CI 95%: −4.08 to 31.2%) but developed less respiratory distress (RD) (difference of −4.7%; CI 95%: −20.6 to 11.05%). Hypoglycemia in 39 WGA was only seen among neonates without MHGD (difference 12.7%; CI95%: 3.9 to 31.5%) just as for the hyperbilirubinemia cases (three). Conclusions: Inquiring about the MHGD on LBW term babies could be useful in the inference of IUGR, although we need other tools so that altogether can help to predict possible complications and to plan preventive actions.

La Diabetes Mellitus (DM) representa una de las Enfermedades Crónicas No Transmisibles (ECNT) más prevalentes del mundo, cuyas complicaciones agudas o emergencias hiperglucémicas más importantes, en el escenario de la medicina de urgencias, son la Cetoacidosis Diabética (CAD), el Estado Hiperglucémico Hiperosmolar (EHH) y la Hipoglucemia, todas ellas asociadas a un control inadecuado o insuficiente de la enfermedad. Con el objetivo de mejorar eficazmente la condición clínica de los pacientes que presentan algún tipo de emergencia hiperglucémica, los médicos del servicio de urgencias deben tener claridad en diversos aspectos clave relacionados con la fisiopatología y el abordaje apropiado para cada situación. En este artículo se reúne la información más actualizada respecto a la definición, epidemiología, etiopatogenia, manifestaciones clínicas, diagnóstico, tratamiento y prevención, de las tres complicaciones agudas de la DM, a fin de ofrecer al clínico una guía práctica para el abordaje y manejo adecuado de los pacientes diabéticos en el contexto de las emergencias hiperglucémicas.
Diabetes Mellitus (DM) represents one of the most prevalent Chronic Noncommunicable Diseases (NCDs) in the world, which acute complications or major hyperglycemic emergencies, in the scenario of emergency medicine, are Diabetic Ketoacidosis (DKA), the State Hyperosmolar hyperglycemic (EHH) and Hypoglycaemia, all associated with inadequate or insufficient control of the disease. In order to effectively improve the clinical condition of patients presenting with some type of hyperglycaemic emergency, emergency department physicians should be clear about various key aspects related to the pathophysiology and the appropriate approach for each situation. This article gathers the most up-to-date information regarding the definition, epidemiology, etiopathogenesis, clinical manifestations, diagnosis, treatment and prevention of the three acute complications of DM mentioned above, in order to offer the clinician a practical guide for the approach and proper management of diabetic patients in the context of hyperglycemic emergencies.

Describimos los resultados del estudio internacional no intervencionista HAT en una muestra de Argentina que evaluó las hipoglucemias graves y no graves en 433 pacientes con diabetes mellitus tipo 1 (DMT1) y 823 con diabetes tipo 2 (DMT2) tratados con insulina, mediante un cuestionario de autoevaluación doble (retrospectivo y prospectivo). La incidencia anual de al menos un evento de hipoglucemia fue 46 episodios/paciente-año en DMT1 y 14.2 en DMT2 (retrospectivo) y 96.5 y 24.6 eventos/paciente/año en DMT1 y DMT2, respectivamente (prospectivo). La hipoglucemia influyó en la calidad de vida (en escala 0-10 de temor a hipoglucemia: 60% en DMT1 y 37.6% en DMT2 puntuó de 5 a 10), en el desempeño cotidiano, laboral o académico (2.1% con DMT1 y el 3.2% con DMT2 no asistieron a su labor por hipoglucemia) y en el mayor consumo de recursos (en DMT1: 66.1% aumentó el monitoreo glucémico, 60.5% la ingesta, 51% las consultas y 60.5% redujo la insulina y el 20.9% el ejercicio, con 3.5% de internación, y en DMT2 aumentó un 46.2% el monitoreo glucémico, 43.8% las consultas, 38.6% la ingesta, el 24.1% redujo y el 13.9% salteó la dosis de insulina, 14.3% suspendió el ejercicio). Se registró mayor número de episodios en el período prospectivo. Es necesario contar con un instrumento para evaluar las hipoglucemias en la práctica clínica y con estrategias para reducir su riesgo. También es importante indagar sobre los episodios y reforzar la educación de pacientes y familiares sobre ajustes de tratamiento ante episodios de hipoglucemia.
We describe the results of the HAT study in 433 Argentinean patients with type 1 diabetes (T1D) and 823 with type 2 diabetes (T2D). HAT was an international non-interventional study assessing severe and non-severe hypoglycaemia in patients with T1D and T2D under insulin treatment through a two-part self-assessment questionnaire (retrospective and prospective). The annual incidence of at least one hypoglycaemic episode was 46 episode/patient/year in T1D and 14.2 in T2D (retrospective), 96.5 and 24.6 episode/patient/year in T1D and T2D, respectively (prospective). Hypoglycaemia affected quality of life (on a scale of 0-10 for fear of hypoglycaemia: 60% in T1D and 37.6% in T2D scored 5 to 10), daily life, occupational or academic performance (2.1% with T1D and 3.2% with T2D did not attend to their work after hypoglycaemia), and induced an increased use of health resources (T1D: 66.1% increased glucose monitoring, 60.5% food intake, 51% consultations, 3.5% hospital admissions; 60.5% reduced insulin and 20.9% exercises; T2D increased 46.2% glucose monitoring, 43.8% consultations, 38.6% food intake, 24.1% reduced and 13.9% skipped the insulin dose and 14.3% suspended exercises). Greater numbers of episodes were recorded in the prospective period. An instrument to assess hypoglycaemia in clinical practice and strategies to reduce their risk are required. It is also important to ask about the episodes and reinforce the education of patients and close relatives on hypoglycaemia prevention and treatment.

Background Hypoglycemia is the main limitation for the achievement of glycemic goals in the treatment of diabetes. Aim To assess the incidence of hypoglycemia in an emergency department. To characterize and identify which patients are at higher risk of having it. Material and Methods We reviewed the electronic records of patients discharged from an adult emergency room with the diagnosis of hypoglycemia between May 2011 and December 2014. Age, sex, diagnosis of diabetes (DM), antidiabetic therapy, glycosylated hemoglobin, creatinine, destination at time of discharge, blood glucose, impairment of conscience, treatment of the event and predictions were recorded. Results Of 175,244 attentions analyzed, 251 in patients aged 69 ± 17 years (54% women) consulted for hypoglycemia (0.14%). Eighty one percent had a type 2 diabetes, 6% a type 1 diabetes and 12% were non-diabetic. Mean blood glucose was 44.1 mg/dl. In diabetic patients, mean glycosylated hemoglobin was 6.5%. Ninety seven percent had impairment of conscience and 77% were admitted to the hospital. Among patients without diabetes, the main comorbidity was the history of a gastric bypass surgery. In type 2 diabetes, glibenclamide used alone or with other medications was involved in 59% of the events, 87% of patients were older than 65 years with a mean glycosylated hemoglobin of 6.3% and 32% had renal failure. Conclusions The incidence of hypoglycemia was low. There were a significant number of events in older patients with type 2 diabetes mellitus and renal failure, who were treated with glibenclamide. Most of these patients had a glycosylated hemoglobin below accepted recommendations.

RESUMEN La disglucemia en el paciente crítico (hiperglucemia, hipoglucemia, variabilidad de la glucemia y el tiempo en rango) es un marcador de severidad de la enfermedad crítica asociada a mayor mortalidad. Sin embargo, dicho impacto parece atenuarse en los pacientes con diabetes mellitus, en particular en aquellos con mal control glucémico premórbido lo cual ha sido denominado "paradoja de la diabetes". Este fenómeno determina que en los nuevos protocolos de control de la glucemia deban ser contemplados los valores de hemoglobina glucosilada (HbA1c) al ingreso a unidad de cuidados intensivos, siendo necesarios nuevos rangos de glucemia objetivos según los valores de la HbA1c. En tal sentido, la HbA1c surge como una herramienta sencilla que permite obtener información de utilidad terapéutica y valor pronóstico en la unidad de cuidados intensivos.
ABSTRACT Dysglycemia in critically ill patients (hyperglycemia, hypoglycemia, glycemic variability and time in range) is a biomarker of disease severity and is associated with higher mortality. However, this impact appears to be weakened in patients with previous diabetes mellitus, particularly in those with poor premorbid glycemic control; this phenomenon has been called "diabetes paradox". This phenomenon determines that glycated hemoglobin (HbA1c) values should be considered in choosing glycemic control protocols on admission to an intensive care unit and that patients' target blood glucose ranges should be adjusted according to their HbA1c values. Therefore, HbA1c emerges as a simple tool that allows information that has therapeutic utility and prognostic value to be obtained in the intensive care unit.

ABSTRACT Objective The oral glucose tolerance test (OGTT) is used in the screening of gestational diabetes, in diagnosis of type 2 diabetes in conjunction with fasting blood glucose and glycated hemoglobin. The aim of this study was to examine the incidence and risk factors of adverse effects of OGTT in patients who underwent bariatric surgery, in addition to proposing standardization for ordering the OGTT in these patients. Subjects and methods This study assessed the incidence of adverse effects in 128 post-bariatric surgery patients who underwent the OGTT. Descriptive and logistic regression analysis were performed, the dependent variables were defined as the presence of signs (tremor, profuse sweating, tachycardia), symptoms (nausea, diarrhea, dizziness, weakness), and hypoglycemia (blood glucose ≤ 50 mg/dL). Results One hundred and seventeen participants (91.4%) were female; 38 (29.7%) participants were pregnant. High incidence (64.8%) of adverse effects was observed: nausea (38.4%), dizziness (30.5%), weakness (25.8%), diarrhea (23.4%), hypoglycemia (14.8%), tachycardia (14.1%), tremor (13.3%), profuse sweating (12.5%) and one case of severe hypoglycemia (24 mg/dL). The presence of signs was associated with hypoglycemia (OR = 8.1, CI 95% 2.6-25.1). The arterial hypertension persisted as a risk factor for the incidence of signs (OR = 3.6, CI 95% 1.2-11.3). Fasting glucose below 75 mg/dL increased the risk of hypoglycemia during the test (OR = 9.5, CI 95% 2.6-35.1). Conclusion In this study, high incidence of adverse effects during the OGTT was observed in post-bariatric surgery patients. If these results are confirmed by further studies, the indication and regulation of the OGTT procedure must be reviewed for these patients.

Foi desenvolvido no Hospital Sírio Libanês um sistema de apoio à decisão de condutas nas linguagens de programação JAVA e Delphi. Foi implantado no sistema um protocolo para tratamento de hipoglicemia que após o diagnóstico através da glicemia capilar e inserção do dado no sistema, inicia-se um processo que finaliza em uma conduta. O objetivo deste estudo foi descrever o processo de implantação deste sistema, além de analisar os dados demográficos das hipoglicemias. É um estudo observacional, transversal, retrospectivo. Os dados foram coletados de 01/2014 a 12/2015.635 episódios de hipoglicemia foram avaliados. 87,1% das 635 hipoglicemias foram leves (50 a 60mg/dL). A unidade de internação oncológica mostrou a menor prevalência de hipoglicemias (17,8%), enquanto internações prolongadas entre16 e 30 dias mostraram maior prevalência (21,6%). As hipoglicemias também foram mais comuns em homens acima de45 anos e em mulheres entre 15 e 44 anos.
A decision support system was developed at Sírio Libanês Hospital using the programming languages JAVA and Delphi. A hypoglycemic protocol was inserted in the system to test the support to clinical decision. After a hypoglycemia diagnosis using the capillary glucose test, the data was inserted in the system and a process was generated with some steps that finished with an intervention procedure. The objective of this study was to describe the system implementationprocess and to analyze demographic characteristics of hypoglycemic episodes. This is an observational,cross-sectional, retrospective study. The data was from January 2014 to December 2015. 635 hypoglycemic episodeswere included in this analysis. 87.1% hypoglycemic episodes were mild. Oncology unit was the one with lower prevalence(17.8%), while a longer stay at the hospital (16 to 30 days) had a high prevalence (21.6%). Hypoglicemic episodes were more common in men over 45 years old and among women between 15 and 44 years old.

Introduction: Hypoglycaemia occurs frequently in hospitalized diabetic patients and increases inpatient morbidity and mortality. In 60 percent of cases, it isnt managed properly. The goal of this study was to determine prevalence, treatment, complications and length of hospital stay related to hypoglycaemia with local patients. Patients and Methods: This study was designed as a prospective series of cases with diabetic patients, hospitalized in internal medicine and surgical services. Results: 105 cases of hypoglycaemia presented in 47 patients, with a mean of 2,21 +/- 1,68 episodes per patient. 53,32 percent of hypoglycaemic episodes presented in surgical patients. The cause was not determined in 49,52 percent (n = 52) of the episodes, and 41,9 percent (n = 44) of them were asymptomatic. 59,57 percent (n = 28) of patients presented complications during their hospital stay, mainly infectious, with no difference between surgical and medical services. Median inpatient stay in the surgical service was of 28 days (RIQ 19-45), and of 16 days (RIQ 11-28) in the internal medicine service. Treatments were modified in 57,45 percent (n = 27)of patients after their first hypoglycaemic episode occurred, 17 in internal medicine service, and 10 in surgical service (p = 0,003). Conclusions: the majority of patients presented at least two hypoglycaemic events, and only in half of were treatments modified in order to prevent another episode, which is more that reported in literature, particularly in internal medicine service, where diabetologists work. Highlighting the large number of undetermined causes of hypoglycaemia, caused mainly by lack of registry, can lead to the creation of a registry form for these kinds of occurrences in order to successfully prevent more episodes and decrease inpatient stay and complications.

To determine glucose levels in late preterm and term newborns at one hour of life in our population, along with the frequency of symptomatic hypoglycemia and it's known risk factors. Descriptive study. Quaid-e-Azam International Hospital [QIH] Islamabad from July 2012 to September 2013. Two hundred and seventy newborns were selected by consecutive purposive non probability sampling who were born at QIH either by spontaneous vaginal delivery or cesarean section. Only healthy neonates were included. Gestational age, weight, fetal and maternal risk factors were assessed. Glucose level was measured by glucometer at 1 hour of life after first feed. Neonates that became symptomatic with low glucose levels were thoroughly studied, readings reconfirmed from laboratory and were promptly managed. Thirty [11%] babies showed sugar level < 30 mg/dl at 1 hour of life. Out of them 18 [60%] were late preterm and 12[40%]were term babies. Out of them 12[40%] babies weighed <2kg, 8[26%] were between 2-2.5 kg and 6[20%] were 2.5-4.0 kg while 4[14%] babies were between 4.0 to 4.6 kg. Only 6[2.2%] newborns became symptomatic with low sugar level. Among symptomatic newnates, 4 mothers had gestational diabetes and other two were with pregnancy induced hypertension [PIH]. Important risk factors were gestational diabetes, PIH, fetal distress and SGA babies. Safest lower glucose level was found to be 30 mg/dl at 1 hour after birth. Plasma glucose levels measured at 1 hour of life in late preterm and term newborns in our population are consistent with international studies. Frequency of symptomatic hypoglycemia is quite low and normal newborns without risk factors do not need screening. However one needs to be vigilant in babies with risk factors

La Diabetes Mellitus representa un problema de salud mundial y nacional, y la hipoglicemia es unade sus más temidas complicaciones. Existe controversia en cuanto a los rangos glicémicos ideales,ya que se ha demostrado mayor mortalidad en pacientes que desarrollan hipoglicemia.Materiales y Métodos: El objetivo del presente estudio fue determinar la incidencia dehipoglicemia en pacientes en la Unidad de Cuidados Intensivos y Encamamiento de MedicinaInterna del Hospital Roosevelt y determinar su mortalidad, comparándola con un grupo control sinhipoglicemia. Es un estudio observacional de casos y controles. Se incluyó como grupo de estudioa 35 pacientes en quienes se documentó hipoglicemia, del 1 de enero al 30 de junio del 2011. Porcada sujeto de estudio se tomó un control que no desarrolló hipoglicemia. Se determinó lamortalidad intra-hospitalaria y a los seis meses de cada grupo.Resultados: Intrahospitalariamente fallecieron 10 pacientes (28.6%) del grupo de hipoglicemia y 3(8.6%) del grupo control (RR 3.33; 95% CI, 1.00 11.09; P=0.0496). A los seis meses habíanfallecido 15 pacientes (42.9%) del grupo de hipoglicemia, y 7 (20.0%) del grupo control (RR 2.14; CI0.997 4.605; P=0.0509). Tres pacientes (8.6%) del grupo de hipoglicemia desarrollaron infecciónnosocomial durante el estudio, y ninguno del grupo control (RR 7.00; CI 0.37 130.70; P=0.1926).Se documentaron 10 re-hospitalizaciones en el grupo de hipoglicemia y 9 en los controles.Conclusión: Este estudio demuestra que hay mayor riesgo de morir en pacientes que desarrollanhipoglicemia durante su estancia hospitalaria comparado con quienes no la realizan.

Intensive insulin therapy, together with carbohydrate counting, is currently considered the best therapeutic strategy for the management of type 1 diabetes mellitus (DM1). However, goals of glycemic control proposed by consensus are still difficult to achieve with this therapy,which has also been associated with weight gain and increased hypoglycemia. Objective: To describe a population of patients with DM1, who were treated with intensive insulin therapy. Material and methods: This descriptive, cross-sectional study included type 1 diabetics who underwent intensive insulin therapy and used different levels of the carbohydrate counting method. All these patients were attending the Type 1 Diabetes Section of the Nutrition Division at theJosé de San Martín Clinical Hospital and they made at least one follow-up visit between July 2011 and July 2012. Only those with complete medical records were included in the study. The following information wastaken from their medical records: sex, age, weight, height, body mass index (BMI), treatment for diabetes, training level in the carbohydrate counting method, frequency of hypoglycemia, glycated hemoglobin (HbA1c) value, duration of the disease, number of follow-up years. The statistical analysis was performed using SPSS 17.0 software, mean and standard deviation (SD) values were calculated. Also the percentages of each variablewere calculated...

INTRODUÇÃO: Hipoglicemia pode ocorrer durante hemodiálise em pacientes diabéticos renais crônicos quando se utiliza dialisato sem glicose. Com soluções de diálise contendo glicose a 90 mg/dL ou mais, isto pode ser prevenido, mas esses pacientes diabéticos podem apresentar glicemias intradialíticas muito elevadas. OBJETIVO: Nosso estudo testou um dialisato com taxas mais reduzidas de glicose tentando prevenir tanto hipo como hiperglicemia nesses pacientes. MÉTODOS: Vinte indivíduos diabéticos de nossa unidade de hemodiálise foram submetidos a três sessões com soluções de diálise com diferentes concentrações de glicose - 55 mg/dL (Fase 55) e 90 mg/dL (Fase 90) - e uma solução sem glicose (Fase ZERO). Glicemias foram medidas em cinco momentos durante cada sessão - antes e aos 30, 60, 150 e 240 min. Resultados inferiores a 70 mg/dL foram considerados como hipoglicemia. RESULTADOS: Três pacientes apresentaram seis episódios de hipoglicemia na Fase 55, mas nenhum paciente apresentou qualquer episódio na Fase 90. Na Fase ZERO, cinco pacientes apresentaram sete episódios. CONCLUSÃO: O dialisato com baixo teor de glicose (55 mg/dL) não preveniu episódios de hipoglicemia durante hemodiálise em pacientes diabéticos, um achado similar ao obtido quando se utilizou solução de diálise sem glicose. O uso de dialisato com glicose a 90 mg/dL não produziu glicemias intradialíticas mais elevadas do que as outras soluções de diálise.
INTRODUCTION: Hypoglycemia can occur during hemodialysis in diabetic chronic renal failure patients when using a dialysate without glucose. With dialysis solutions with glucose 90 mg/dL or more, this is preventable, but diabetic patients could present higher intradialytic glycemias. OBJECTIVE: We tested a dialytic fluid with a lower level of glucose trying to prevent both hypo and hyperglycemia in these patients. METHODS: Twenty diabetic individuals from our hemodialysis unit were submitted to 3 sessions with dialysis solutions with two different glucose concentrations - 55 mg/dL (Phase 55), and 90 mg/dL (Phase 90) - and a glucose-free one (Phase ZERO). Plasma glucose levels were measured at five moments during each session - before and at 30, 60, 90 and 240 min. Results under 70 mg/dL were considered as hypoglycemia. RESULTS: Three patients presented 6 episodes of hypoglycemia in Phase 55, but no patient presented any episode in Phase 90. In Phase ZERO, five patients presented 7 episodes. CONCLUSION: This dialysate with a low level of glucose (55 mg/dL) did not prevent hypoglycemia episodes during hemodialysis in diabetic patients, these occurrences being similar to that when using a dialysate without glucose. The use of a 90 mg/dL glucose dialysis solution did not induce higher intradialytic glycemia levels than the other dialysis solutions.
