ABSTRACT
OBJECTIVES@#To investigate the risk factors for diabetic ketoacidosis (DKA) in children/adolescents with type 1 diabetes mellitus (T1DM) and to establish a model for predicting the risk of DKA.@*METHODS@#A retrospective analysis was performed on 217 children/adolescents with T1DM who were admitted to General Hospital of Ningxia Medical University from January 2018 to December 2021. Among the 217 children/adolescents,169 cases with DKA were included as the DKA group and 48 cases without DKA were included as the non-DKA group. The risk factors for DKA in the children/adolescents with T1DM were analyzed, and a nomogram model was established for predicting the risk of DKA in children/adolescents with T1DM.@*RESULTS@#For the 217 children/adolescents with T1DM, the incidence rate of DKA was 77.9% (169/217). The multivariate logistic regression analysis showed that high levels of random blood glucose, hemoglobin A1c (HbA1c), blood ketone body, and triglyceride on admission were closely associated with the development of DKA in the children/adolescents with T1DM (OR=1.156, 3.2031015, 20.131, and 9.519 respectively; P<0.05). The nomogram prediction model had a C-statistic of 0.95, with a mean absolute error of 0.004 between the risk of DKA predicted by the nomogram model and the actual risk of DKA, indicating that the model had a good overall prediction ability.@*CONCLUSIONS@#High levels of random blood glucose, HbA1c, blood ketone body, and triglyceride on admission are closely associated with the development of DKA in children/adolescents with T1DM, and targeted intervention measures should be developed to reduce the risk of DKA.

Introducción: El desarrollo de la tolerancia inmunológica frente a los autoantígenos se denomina autotolerancia. La Diabetes Mellitus tipo 1A (1ADM) es un trastorno metabólico secundario a la destrucción autoinmune de las células beta pancreáticas e insulitis. La miastenia grave (MG) es una enfermedad autoinmune causada por el bloqueo postsináptico de la placa mioneural por AAcs contra los receptores de acetilcolina (ACRA) o contra moléculas de la membrana postsináptica. La asociación entre DM1A y MG se puede observar en el síndrome poliglandular tipo III, caracterizado por enfermedad autoinmune de la glándula tiroides asociada con otras entidades autoinmunes. Método: Reporte de Casos, cuatro pacientes entre 7-19 años, con asociación de MG y DM1A atendidos en el Hospital Garrahan. Conclusión: La Tiroiditis de Hashimoto y la Enfermedad Celíaca son las enfermedades autoinmunes relacionadas más frecuentemente con DM1A en nuestra población. La bibliografía describe la asociación de MG y Tiroiditis de Hashimoto y su coexistencia con DM1A se describe en el Síndrome Poliglandular III. En este trabajo presentamos 4 casos de DM1A asociado con MG fuera de dicho síndrome (AU)
Introduction: The development of immune tolerance to autoantibodies (AAbs) is referred to as self-tolerance. Type 1A Diabetes Mellitus (1ADM) is a metabolic disorder secondary to autoimmune destruction of pancreatic beta cells and insulitis. Myasthenia gravis (MG) is an autoimmune disease caused by postsynaptic blockade of the myoneural plate by AAbs against acetylcholine receptors (Acra) or against postsynaptic membrane molecules. The association between 1ADM and MG may be observed in polyglandular syndrome type III, characterized by autoimmune disease of the thyroid associated with other autoimmune conditions. Methods: Case report; four patients between 7-19 years old, with an association of MG and 1ADM seen at the Garrahan Hospital. Conclusion: Hashimoto's thyroiditis and celiac disease are autoimmune diseases most frequently related to 1ADM in our population. In the literature, the association of MG and Hashimoto's thyroiditis has been described and its coexistence with 1ADM is reported in polyglandular syndrome III. In this study we present 4 cases of 1ADM associated with MG unrelated to this syndrome. (AU)

Introduction: The lack of metabolic control in patients with Type 1 Diabetes Mellitus (T1DM) can cause severe complications and reduce their life expectancy. Transition into adolescence among children with T1DM effects important changes that could negatively influence their metabolic control. Purpose: To determine knowledge, perceptions, needs and challenges of Dominican adolescents with T1DM. Methodology: Phone interviews to adolescents with T1DM between 14 and 18 years. Analysis included coding using the Health Belief Model, and using Nvivo, with a deductive and inductive approach. Results: Participants reported a high level of perceived susceptibility to complications, and severity associated to an incurable disease that causes severe complications. Within modifying factors, the family socioeconomic level was identified as relevant, and the role of support networks in managing their disease was mentioned as an external variable. Conclusions: Culturally, relevant interventions are needed to improve metabolic control and psychosocial aspects among Dominican adolescents with T1DM, including the use of a self-management mobile application; in addition, incorporating perspectives, context realities and knowledge of adolescents in developing therapeutical education strategies about T1DM could improve the impact of these strategies
Introducción: el descontrol metabólico en pacientes con diabetes tipo 1 (DMT1) puede provocar complicaciones severas y reducir la esperanza de vida. La transición a la adolescencia en jóvenes con DMT1 determina cambios importantes que pueden influenciar negativamente el control metabólico. Propósito: determinar el nivel de conocimiento, las percepciones, las necesidades y los desafíos de los adolescentes dominicanos con DMT1. Metodología: entrevistas telefónicas a adolescentes con DMT1, entre 14 y 18 años. El análisis incluyó la codificación con base al Modelo de Creencias de Salud, utilizando NVivo, a través de un abordaje deductivo e inductivo. Resultados: participantes reportaron un alto nivel de susceptibilidad percibida de sufrir complicaciones y una percepción de severidad asociada a una enfermedad incurable que causa complicaciones severas. En los factores modificadores se destacan determinantes sociales como el nivel socioeconómico de la familia y, en las variables externas, el rol de las redes de apoyo en el manejo de la enfermedad. Conclusiones: se requieren intervenciones culturalmente relevantes para mejorar el control metabólico y los aspectos psicosociales en los adolescentes dominicanos con DMT1, como sería una aplicación móvil para el automanejo; además, incorporar las perspectivas, las realidades contextuales y los conocimientos de los adolescentes en las estrategias de educación terapéutica sobre la DMT1 favorecería su impacto

ABSTRACT Insulin antibodies (IAs) induced by exogenous insulin rarely cause hypoglycemia. However, insulin autoantibodies (IAAs) in insulin autoimmune syndrome (IAS) can cause hypoglycemia. The typical manifestations of IAS are fasting or postprandial hypoglycemia, elevated insulin level, decreased C-peptide levels, and positive IAA. We report a 45-year-old male with type 1 diabetes mellitus (T1DM) treated with insulin analogues suffering from recurrent hypoglycemic coma and diabetic ketoacidosis (DKA). His symptoms were caused by exogenous insulin and were similar to IAS. A possible reason was that exogenous insulin induced IA. IA titers were 61.95% (normal: 300 mU/L and < 0.02 nmol/L when hypoglycemia occurred. Based on his clinical symptoms and other examinations, he was diagnosed with hyperinsulinemic hypoglycemia caused by IA. His symptoms improved after changing insulin regimens from insulin lispro plus insulin detemir to recombinant human insulin (Gensulin R) and starting prednisone.
Los anticuerpos contra la insulina (AI) inducidos por la insulina exógena raramente causan hipoglucemia. No obstante, los autoanticuerpos contra la insulina (AIA) en el síndrome autoinmune de insulina (SAI) pueden causar hipoglucemia. Las manifestaciones típicas del SAI son la hipoglucemia en ayunas o posprandial, niveles elevados de insulina, la disminución del nivel de péptido C y AIA positivos. Presentamos un paciente hombre de 45 años con diabetes mellitus de tipo 1 (DMT1) tratado con análogos de insulina, que sufría comas hipoglucémicos recurrentes y cetoacidosis diabética (CAD). Sus síntomas fueron causados por la insulina exógena y fueron similares al SAI. La posible razón fue que la insulina exógena indujo AI. El título de AI era del 61,95% (Normal: 300 mU/L y < 0,02 nmol/L cuando se producía la hipoglucemia. Basados en sus síntomas clínicos y otros exámenes, se le diagnosticó hipoglucemia hiperinsulinémica causada por la AI. Sus síntomas mejoraron después de cambiar el régimen de insulina de lispro más insulina detemir a insulina humana recombinante (Gensulin R) y de empezar a tomar prednisona.

BACKGROUND@#Associations of acute glycemic complications with season and ambient temperature have been reported in general population with diabetes. However, little is known about the risks of acute glycemic complications in relation to season and ambient temperature in pregnant women, who are likely to be even more vulnerable. This work aimed to investigate the associations of season and ambient temperature with pregnancies complicated with hyperglycemia emergency or severe hypoglycemia.@*METHODS@#Two separate case-control studies were nested within 150,153 pregnancies by women with type 1, type 2, or gestational diabetes between 2009 and 2014 in Taiwan. Hyperglycemia emergency (mainly diabetic ketoacidosis and hyperosmolar hyperglycemic state) and severe hypoglycemia occurred in 77 and 153 diabetic pregnancies (cases), respectively. Ten control pregnancies were randomly selected for each case by matching each case pregnancy on type of diabetes (i.e., T1DM, T2DM, or GDM), maternal age on the date of acute glycemic complication occurrence (i.e., index date), and "length of gestation at risk" (i.e., period between conception and index date). Meteorological parameters were retrieved from 542 meteorological monitoring stations across Taiwan during 2008-2014. Conditional logistic regression analysis with generalized estimation equation was separately performed to estimate the covariate adjusted odds ratios (ORs) of each of the two acute glycemic complications in association with season and ambient temperature within 30 days prior to the index date.@*RESULTS@#Compared to summer, winter season was associated with a significantly elevated risk of severe hypoglycemia with an OR of 1.74 (95% confidence interval (CI) 1.08-2.79). The OR of hyperglycemic emergency was also elevated in winter season at OR of 1.88, but the significance is only marginal (95% CI 0.97-3.64, p = 0.0598). Subgroup analyses further noted that such seasonal variation was also observed in pregnancies with pre-pregnancy type 1 diabetes and gestational diabetes. On the other hand, ambient temperature was not significantly associated with the two acute glycemic complications.@*CONCLUSIONS@#A moderately but significantly elevated risk of severe hypoglycemia was found in pregnant women with diabetes during winter season, and such increased risk was more evident in pregnancies with T1DM.

Resultados Realizaram retinografia 727 pacientes diabéticos, que tinham entre 14 e 91 anos, sendo a maioria com 60 anos ou mais (53,2%), do sexo feminino (68%) e brancos (87,6%). Não apresentavam retinopatia diabética 467 (64,2%) pacientes, 125 (17,2%) tinham retinopatia diabética não proliferativa, 37 (5,1%) retinopatia diabética não proliferativa grave e/ou suspeita de edema macular, 65 (8,9%) retinopatia diabética proliferativa, 21 (2,9%) suspeita de outras patologias, e as imagens de 12 (1,7%) pacientes eram insatisfatórias. Foram considerados de alto risco (aqueles com retinopatia diabética não proliferativa grave e/ou edema macular, retinopatia diabética proliferativa ou imagem insatisfatória) 114 (15,68%) pacientes. Conclusão O rastreio de retinopatia diabética com retinografia colorida possibilitou a detecção de pacientes diabéticos de alto risco que necessitavam atendimento com brevidade, permitindo o acesso deles à consulta oftalmológica e diminuindo a morbidade da doença relacionada ao tratamento tardio. Os demais foram encaminhados à Atenção Primária para regulamentação, por meio do Sistema de Regulação.
ABSTRACT Objective To evaluate the impact of diabetic retinopathy (DR) screening using color retinography in diabetic patients. Methods Retrospective descriptive study, evaluating reports of all retinographs performed since the implementation of the protocol for screening for diabetic retinopathy in diabetic patients followed up at the endocrinology outpatient clinic of a tertiary hospital of the Unified Health System, from May 2018 to May 2020. Results 727 diabetic with age range from 14 to 91 years old, the majority being 60 years old or older (53.2%), female (68%) and white (87.6%), patients underwent retinography. Of the patients, 467 (64.2%) did not have DR, 125 (17.2%) had non-proliferative DR, 37 (5.1%) had severe non-proliferative DR and/or suspected macular edema, 65 (8.9%) had proliferative DR, 21 (2.9%) had suspicion signs of other pathologies and 12 (1.7%) had unsatisfactory images. A total of 114 (15.68%) patients were considered at high risk (those with severe non-proliferative NP and/or EM, proliferative DR or poor image) and were referred for comprehensive ophthalmic evaluation. Conclusion The screening of RD with color retinography enabled the detection of high-risk diabetic patients who needed assistance sooner and enabled their access to ophthalmologic consultation, which decreased disease morbidity. The others were referred to primary care for regulation through the Regulation System (SISREG).

ABSTRACT Objectives: To assess the prevalence of psychiatric disorders in patients with type 1 diabetes mellitus (T1D) and to compare patients with and without psychiatric disorder. Materials and methods: We made a cross-sectional study including patients with T1D assisted in the outpatient clinics of the Brazilian National Health System. To assess depression and anxiety, we used the PHQ-9 questionnaire and the DSM-5th edition criteria, respectively. B-PAID evaluated the level of emotional distress associated with diabetes; EAT-26, eating disorders; SCI-R, adherence to the proposed clinical treatment. Results: We analyzed 166 patients aged 33 (22-45.2) years, 53.6% female. The prevalence of depression and anxiety was 20.5% and 40.4%, respectively. HbA1c was worse in the depressed (9.0% vs. 8.4%, p = 0.008), in the anxious ones (9.0% vs. 8.3%, p = 0.012) and in the patients with high levels of B-PAID (8.8 % vs. 8.3 %, p = 0.009). There was no difference in the prevalence of complications related to diabetes. Conclusions: The prevalence of psychiatric disorders and emotional distress related to diabetes was high in our population of T1D patients, and depression and high levels of B-PAID were associated with the worse glycemic control.

Introdução: O diabetes mellitus tipo 1 (DM1) se caracteriza pela destruição das células beta das ilhotas pancreáticas, manifestando-se em hiperglicemia sintomática, devido a um déficit absoluto de insulina, gerando dependência vital de insulina exógena. É considerado típico em crianças e adolescentes; entretanto, pode se desenvolver em qualquer idade. Há inúmeros achados de alterações auditivas em pessoas com DM1, porém não há estudos em outras áreas da Fonoaudiologia. Objetivo: relatar o caso de um adolescente com diagnóstico recente de diabetes mellitus tipo I e alterações fonoaudiológicas na área da fala - desvio fonético no fonema /r/ - e de processamento auditivo. Apresentação do caso: Adolescente de 11 anos de idade vem encaminhado para Fonoaudiologia por não conseguir executar o /r/, com histórico de atendimento fonoaudiológico prévio. Logo após avaliação de fala e início do tratamento, realizou exame de processamento auditivo, que apontou alteração. Após 30 sessões de fonoterapia, o processamento auditivo foi tratado com sucesso. Discussão: Os achados do caso corroboram com o descrito na literatura consultada. Conclusão: O presente estudo se faz pertinente devido à escassez de estudos com mais participantes, com outras áreas da Fonoaudiologia que não somente a Audiologia.
Introduction: Type 1 diabetes mellitus (DM1) is characterized by the destruction of beta cells of pancreatic islets, manifesting in symptomatic hyperglycemia, due to an absolute insulin deficit, generating vital dependence on exogenous insulin. It is considered typical in children and adolescents; however, it can develop at any age. There are countless findings of auditory alterations in people with DM1, but there are no studies in other areas of Speech-Language Pathology. Objective: to report the case of an adolescent with a recent diagnosis of type I diabetes mellitus and Speech-Language Pathology disorders in the speech area - phonetic deviation in the phoneme /r/ - and auditory processing. Case report: An 11-year-old teenager arrives at the Speech-Language Pathology department for not being able to perform the /r/. Right after speech assessment and treatment initiation, he underwent an auditory processing exam, which showed changes. After 30 sessions of speech therapy, auditory processing was successfully treated. Discussion: The findings of the case corroborate with those described in the consulted literature. Conclusion: The present study is relevant due to the scarcity of studies with more participants, with other areas of Brazilian Speech-Language Pathology, other than only Audiology.

SUMMARY OBJECTIVE: To assess the prevalence of altered ankle-brachial index (<0.9 or >1.3) in patients with type 1 diabetes and to compare it with the presence of subclinical atherosclerosis by carotid ultrasound. METHODS: Prospective, cross-sectional study in which 45 adults with type 1 diabetes were evaluated (age 34±10 years, 46.7% men). The data collected included anamnesis, clinical evaluation, calculation of the ankle-brachial index (relationship between systolic blood pressure in the ankle and brachial artery), and performance of carotid ultrasound. RESULTS: Thirty-two patients had ankle-brachial index >1.3 (66.7%) and no patient had ankle-brachial index <0.9. Carotid echocardiography was performed on 21 patients, 4 (19%) of whom had atherosclerosis. Age >35 years and ankle-brachial index >1.4 showed a good correlation with atherosclerosis (r=0.49, p=0.021; r=0.56, p=0.008, respectively). A model associating age >35 years and ankle-brachial index >1.4 showed an excellent relationship with atherosclerosis (r=0.59, p=0.004). CONCLUSIONS: Our study showed that vascular calcification (ankle-brachial index >1.4) was frequent in this population with type 1 diabetes and associated with subclinical atherosclerosis. A model combining ankle-brachial index >1.4 and age >35 years showed an excellent correlation with atherosclerosis and can assist in clinical suspicion and optimize the request for additional tests.

ABSTRACT Objective: People with Down's syndrome (DS) have a higher risk of developing type 1 diabetes mellitus (T1D) and may have specific clinical features compared to T1D patients without DS. This study evaluated the clinical and laboratory aspects of T1D in children and adolescents with DS in an admixed population. Subjects and methods: A case-control study comparing patients with T1D and DS (T1D+DS) to patients with T1D without DS (T1D controls) from two tertiary academic Hospitals in São Paulo, Brazil. Results: The sample consisted of 9 patients with T1D+DS and 18 T1D age and sex-matched controls. Anti-glutamic acid decarboxylase 65 antibodies were positive in 7/7 of the 9 T1D+DS patients, confirming the presence of diabetes autoimmunity in this group. Mean age at diagnosis of T1D was 4.9 ± 3.9 years in the T1D+DS group and 6.4 years ± 3 in the T1D control group; early diagnosis (<2 years old) occurred in three T1D+DS patients but only in one T1D control patients, both suggesting lower age of diagnosis in T1D+DS group, although without statistical significance (p = 0.282 and p = 0.093, respectively). The T1D+DS group presented lower total insulin dose (0.7 IU/kg/day ± 0.2) and HbA1c (7.2% ± 0.6) than the control group (1.0 IU/kg/day ± 0.3 and 9.1% ± 0.7, respectively) (p = 0.022 and p = 0.047, respectively). Conclusion: We confirmed the autoimmune etiology of diabetes in people with DS in this admixed population. T1D+DS patients developed diabetes earlier and achieved better metabolic control with a lower insulin dose than T1D controls. These findings are in agreement with previous studies in Caucasian populations.

A hipoglicemia é uma das principais complicações frente ao manejo inadequado do diabetes, com destaque para a hipoglicemia grave que configura-se como um problema relevante para a manutenção da qualidade de vida dos indivíduos. Os objetivos do presente estudo foram caracterizar os episódios de hipoglicemia grave em pacientes com diabetes em unidades de internação clínica; analisar a associação entre os fatores de risco e os episódios de hipoglicemia grave de pacientes com diabetes em unidade de internação; estimar o tempo de sobrevida até o episódio hipoglicêmico grave. A metodologia empregada para esse estudo considerou casos episódios hipoglicêmicos graves, definidos por valores glicêmicos abaixo de 50 mg/dL. Foram considerados controles os episódios hipoglicêmicos não graves definidos por valores glicêmicos entre 51 a 70mg/dl. Considerou-se como fatores associados à hipoglicemia grave variáveis propostas pela revisão integrativa de literatura realizada para a construção dessa pesquisa. Ainda, também foi analisado o diagnóstico de enfermagem risco de glicemia instável da nomenclatura NANDA-I e sua pertinência quanto aos fatores de risco associados à ocorrência de episódios de hipoglicemia grave. A coleta de dados desenvolveu-se através de análise documental retrospectiva. Foram observados 47 episódios de hipoglicemia grave e 60 episódios de hipoglicemia não grave, respectivamente caso e controle. Os fatores de risco para hipoglicemia grave com evidências na literatura e que foram validados neste estudo caso- controle foram: escolaridade; terapia insulínica; uso de insulinas associadas; modificação recente da dose; insuficiência renal; outras comorbidades; episódio hipoglicêmico anterior e habilidade deficiente para o autocuidado. Identificou-se que o tempo de sobrevida até o episódio hipoglicêmico configura-se em uma curva descendente.A média de tempo que uma pessoa sobrevive até o desfecho de hipoglicemia grave mostrou que o paciente que tem diabetes e está internado tem chances progressivamente maiores de desenvolver episódio de hipoglicemia grave logo nos primeiros dias de internação. Frente aos resultados obtidos, sugere-se que novos estudos sejam realizados com o objetivo descrever aprofundadamente os mecanismos de associação destas variáveis com o episódio hipoglicêmico grave. A identificação da magnituddos fatores de risco para hipoglicemia grave, apresentada através do estudo caso-controle, fornece bases para a construção de instrumentos padronizados de avaliação adequada de pacientes com diabetes em unidades de internação.
Hypoglycemia is one of the main complications in the face of inadequate management of diabetes, where severe hypoglycemia is a relevant problem in terms of maintaining the quality of life of individuals. The objectives of the study were to characterize episodes of severe hypoglycemia in patients with diabetes in clinical inpatient units; to analyze the association between risk factors and episodes of severe hypoglycemia in patients with diabetes in the inpatient unit; estimate the survival time until the severe hypoglycemic episode. The methodology used for this study considered cases of severe hypoglycemic episodes, defined by glycemic values below 50 mg / dL. Non-severe hypoglycemic episodes were defined as controls defined by glycemic values between 51 to 70mg / dl. Factors associated with severe hypoglycemia were considered as variables proposed by the integrative literature review carried out for the construction of this research. Still, the Nursing Diagnosis Risk of Unstable Glycemia of the NANDA-I Nomenclature and its relevance regarding the risk factors associated with the occurrence of episodes of severe hypoglycemia were also analyzed. Data collection was developed through retrospective document analysis. 47 episodes of severe hypoglycemia and 60 episodes of non-severe hypoglycemia were analyzed, case and control, respectively. The risk factors for severe hypoglycemia with evidence in the literature that were validated in this case-control study were: education; insulin therapy; use of associated insulins; recent dose modification; renal insufficiency; other comorbidities; previous hypoglycemic episode and deficient ability for self-care. It was identified that the survival time until the hypoglycemic episode is configured in a descending curve. The average time that a person survives until the outcome of severe hypoglycemia showed that the patient who has diabetes and is hospitalized has a progressively greater chance of developing an episode of severe hypoglycemia in the first days of hospitalization. In view of the results obtained, it is suggested that further studies be carried out in order to describe in depth the mechanisms of association of these variables with the severe hypoglycemic episode. The identification of the magnitude of risk factors for severhypoglycemia, presented through the case-control study, provides the basis for the construction of standardized instruments for adequate assessment of patients with diabetes in inpatient units.

Los objetivos del estudio fueron caracterizar episodios de hipoglucemia severa en pacientes con diabetes en unidades de internación clínica; analizar la asociación entre factores de riesgo y episodios de hipoglucemia severa en pacientes con diabetes en la unidad de internación; Estime el tiempo de supervivencia hasta el episodio de hipoglucemia grave. La metodología utilizada para este estudio consideró casos de episodios hipoglucémicos graves, definidos por valores glucémicos inferiores a 50 mg / dL. Se consideraron controles los episodios hipoglucémicos no graves definidos como valores glucémicos entre 51 y 70 mg / dl. Los factores asociados a la hipoglucemia severa fueron considerados como variables propuestas por la revisión integradora de la literatura realizada para la construcción de esta investigación. Aún así, también se analizó el Diagnóstico de Enfermería Riesgo de Glucemia Inestable de la Nomenclatura NANDA-I y su relevancia con respecto a los factores de riesgo asociados a la ocurrencia de episodios de hipoglucemia severa. La recolección de datos se desarrolló a través del análisis retrospectivo de documentos. Se analizaron 47 episodios de hipoglucemia severa y 60 episodios de hipoglucemia no severa, caso y control, respectivamente. Los factores de riesgo de hipoglucemia severa con evidencia en la literatura que fueron validados en este estudio de casos y controles fueron: educación; terapia con insulina; uso de insulinas asociadas; modificación reciente de la dosis; insuficiencia renal; otras comorbilidades; episodio hipoglucémico previo y capacidad deficiente para el autocuidado. Se identificó que el tiempo de supervivencia hasta el episodio hipoglucémico se configura en una curva descendente. El tiempo promedio que una persona sobrevive hasta el resultado de una hipoglucemia severa mostró que el paciente que tiene diabetes y está hospitalizado tiene una probabilidad progresivamente mayor de desarrollar un episodio de hipoglucemia severa en los primeros días de hospitalización. A la vista de los resultados obtenidos, se sugiere realizar más estudios con el fin de describir en profundidad los mecanismos de asociación de estas variables con el episodio de hipoglucemia grave. La identificación de la magnitud de los factores de riesgo de hipoglucemia severa, presentada a través del estudio de casos y controles, proporciona la base para la construcción de instrumentos estandarizados para la evaluación adecuada de pacientes con diabetes en unidades de internación.

Introducción: Con frecuencia, los pacientes diabéticos presentan dolor neuropático como complicación de su enfermedad. Objetivo: Identificar las ventajas de la ozonoterapia sistémica en pacientes diabéticos insulinodependientes con dolor neuropático. Métodos: Se realizó un estudio descriptivo en diabéticos insulinodependientes con dolor neuropático que acudieron a la Clínica del Dolor del Hospital Clínico Quirúrgico Hermanos Ameijeiras entre febrero de 2014 hasta enero de 2019. A todos se les cuantificó el dolor, la presencia de parestesias, la fuerza muscular, el reflejo aquiliano y la hemoglobina glicosilada. Se administraron 15 sesiones de ozono vía rectal y 6 de autohemoterapia mayor. Se compararon los resultados de la primera sesión y en la última (8 semanas de tratamiento). Resultados: El 45,3 por ciento tenían 60 años o más, 59 por ciento eran del sexo femenino y 89,3 por ciento tenían 15 o más años de evolución de la diabetes. En la primera consulta la intensidad del dolor en 100 por ciento osciló entre 7 y 10 de la escala numérica verbal y todos presentaron parestesias. En 59,3 por ciento existió disminución de la fuerza muscular, 62 por ciento presentó reflejo aquiliano disminuido y 88 por ciento hemoglobina glicosilada mayor o igual a 12 por ciento. Estos síntomas mejoraron a las ocho semanas. Conclusiones: Las probadas propiedades analgésicas y antiinflamatorias del ozono lo convierten en la actualidad en una herramienta terapéuticas de las más eficientes para el control del dolor crónico en pacientes diabéticos insulinodependientes(AU)
Introduction: Frequently, diabetic patients present neuropathic pain as a complication of their disease. Objective: To identify the advantages of systemic ozone therapy for insulin-dependent diabetic patients with neuropathic pain. Methods: A descriptive study was carried out with insulin-dependent diabetic patients with neuropathic pain who attended the Pain Clinic of Hermanos Ameijeiras Clinical-Surgical Hospital between February 2014 until January 2019. All of them were quantified pain, the presence of paresthesias, muscle strength, ankle jerk reflex, and glycosylated hemoglobin. The patients received fifteen sessions of rectal ozone and six sessions of major self-hemotherapy. We compared the outcomes after the first session and after the last one (eight weeks). Results: 45.3 percent were 60 years or older, 59 percent were female, and 89.3 percent had a natural history of diabetes of 15 years or more. In the first hospital visit, the intensity of 100 percent pain ranged between 7 and 10 according to the verbal numeric scale, and all presented paresthesias. In 59.3 percent, there was a decrease in muscle strength, 62 percent had decreased ankle jerk reflex, and 88 percent had glycosylated hemoglobin higher than or equal to 12 percent. These symptoms improved at week eight. Conclusions: The proven analgesic and anti-inflammatory properties of ozone make it currently a therapeutic tool among the most efficient for controlling chronic pain in insulin-dependent diabetic patients(AU)

Resumen: Introducción: Un mal control metabólico en pacientes con Diabetes Mellitus tipo 1 (DM1) se asocia a complica ciones a corto y largo plazo. Los adolescentes con Diabetes tipo 1 presentan peor control metabólico comparado con pacientes de otros grupos etarios. Escasos estudios han demostrado una asociación entre síntomas depresivos de las madres con el control metabólico de sus hijos adolescente. Objetivo: Evaluar la asociación entre síntomas depresivos maternos y control metabólico de adolescentes con DM1. Sujetos y Método: Estudio observacional transversal realizado en adolescentes, edades 10 a 18 años, con diagnóstico de DM1 de más de un año de evolución y sus madres. Se aplicó test de Beck II, cuestionario de depresión infantil, cuestionario SALUFAM y cuestionario de datos sociodemográficos. Se realizó hemoglobina glicosilada capilar, como marcador de control metabólico. Resultados: Se estudiaron 86 parejas (madre-hijo adolescente), adolescentes de edad media 14.04 años y 5.95 años de evolución de DM1. El 25.6% (n 22) de las madres presentó síntomas depresivos, asociándose a peor control metabólico en sus hijos (HbA1c: 7.66% y 8.91%, p < 0.001). El 17.9% de adolescentes presentó síntomas depresivos, no asociándose a síntomas depresivos maternos ni a peor control metabólico. Los síntomas depresivos maternos se asociaron a menor nivel educacional materno y pater no, mayor número de hijos en la familia, presencia de otros hermanos con enfermedades crónicas y a mayor vulnerabilidad en salud (SALUFAM). Conclusiones: La presencia de síntomas depresivos maternos se asocia a peor control metabólico en el adolescente con DM1, siendo fundamental un enfoque multidisciplinario familiar para obtener mejores resultados metabólicos en los adolescentes.
Abstract: Introduction: Poor metabolic control in patients with Type 1 Diabetes Mellitus (T1DM) is associated with short- and long-term complications. Adolescents with T1DM present poorer metabolic control than patients of other age groups. Few studies have shown an association between mothers with depressive symptoms and the metabolic control of their adolescent children. Objective: To evaluate the associa tion between maternal depressive symptoms and metabolic control of their adolescents with T1DM. Subjects and Method: Cross-sectional observational study carried out with adolescents aged between 10 and 18 years, with T1DM diagnosis of at least 1 year ago and their mothers. The Beck Depression Inventory-II and the SALUFAM questionnaire were applied, and sociodemographic data were co llected. Glycosylated hemoglobin from capillary blood was used as a marker of metabolic control. Results: 86 couples (mother-adolescent children) were studied. The average age of the adolescents was 14.04 years and the average evolution time of T1DM was 5.95 years. 27.325.6% of mothers had depressive symptoms, which was associated with worse metabolic control of their children (HbA1c of 7.66% and 8.91%, p-value <0.001). 17.9% of adolescents had depressive symptoms, which was not associated with maternal depressive symptoms or worse metabolic control. Maternal depressive symptoms were also associated with lower maternal and paternal educational levels, high number of children in the family, presence of other siblings with chronic illnesses, and high health vulnera bility (SALUFAM). Conclusions: The mother's depressive symptoms can be associated with worst metabolic control in T1MD adolescents. It is fundamental a multidisciplinary family approach to get better metabolic controls in T1DM adolescents.

OBJECTIVES@#To compare the differences in clinical characteristics between Type 1 diabetes mellitus (T1DM) and fulminant Type 1 diabetes mellitus (FT1DM), and to reduce the missed diagnosis, misdiagnosis, and mistreatment of FT1DM by medical staff.@*METHODS@#A total of 101 hospitalized patients with T1DM (including 8 cases of FT1DM) were enrolled in this study from Changsha Central Hospital between June 2012 and December 2018. Clinical characteristics of the 8 FT1DM patients were collected and compared with all T1DM patients.@*RESULTS@#All FT1DM patients were adult with the average age of (30.25±5.28) years old, accompanied by severe diabetic ketoacidosis (DKA) occurred within 1 week after onset. Moreover, pancreatic beta cells in these patients were destroyed and the islet-related antibodies were negative, while the serum pancreatic enzyme levels were increased. Compared with classic T1DM patients, the plasma glucose levels in FT1DM patients were much higher [(41.89±12.54) mmol/L vs (22.57±9.74) mmol/L], but glycosylated hemoglobin (HbA1c) and fasting C peptide levels were significantly lower [(6.08±0.41)% vs (10.87±2.46%)%, @*CONCLUSIONS@#The onset time of FT1DM patients is very urgent via driving DKA. These patients have higher blood glucose concentration than classic T1DM patients, accompanied by electrolyte disturbances, impaired renal function, partially impaired liver function, as well as gastrointestinal symptoms and elevated trypsin. Most FTDM patients are adolescents and adults with no gender difference, especially pregnant women who are at high risk. Lifelong insulin dependence in FT1DM patients should be paid more attention in clinical treatment.

Painful diabetic neuropathy (PDN) is a diabetes mellitus complication. Unfortunately, the mechanisms underlying PDN are still poorly understood. Adenosine triphosphate (ATP)-gated P2X7 receptor (P2X7R) plays a pivotal role in non-diabetic neuropathic pain, but little is known about its effects on streptozotocin (STZ)-induced peripheral neuropathy. Here, we explored whether spinal cord P2X7R was correlated with the generation of mechanical allodynia (MA) in STZ-induced type 1 diabetic neuropathy in mice. MA was assessed by measuring paw withdrawal thresholds and western blotting. Immunohistochemistry was applied to analyze the protein expression levels and localization of P2X7R. STZ-induced mice expressed increased P2X7R in the dorsal horn of the lumbar spinal cord during MA. Mice injected intrathecally with a selective antagonist of P2X7R and P2X7R knockout (KO) mice both presented attenuated progression of MA. Double-immunofluorescent labeling demonstrated that P2X7R-positive cells were mostly co-expressed with Iba1 (a microglia marker). Our results suggest that P2X7R plays an important role in the development of MA and could be used as a cellular target for treating PDN.

Patients with diabetic peripheral neuropathy experience debilitating pain that significantly affects their quality of life (Abbott et al., 2011), by causing sleeping disorders, anxiety, and depression (Dermanovic Dobrota et al., 2014). The primary clinical manifestation of painful diabetic neuropathy (PDN) is mechanical hypersensitivity, also known as mechanical allodynia (MA) (Callaghan et al., 2012). MA's underlying mechanism remains poorly understood, and so far, based on symptomatic treatment, it has no effective therapy (Moore et al., 2014).

ABSTRACT Objective: To analyze the variables associated with the presence of diabetic ketoacidosis in type 1 diabetes mellitus (T1DM) diagnosis and its impact on the progression of the disease. Methods: We reviewed the records of 274 children and adolescents under 15 years, followed in a Pediatric Endocrinology clinic of a university hospital in Curitiba-PR. They had their first appointment between January 2005 and April 2015. Results: Most patients received their T1DM diagnosis during a diabetic ketoacidosis episode. The associated factors were: lower age and greater number of visits to a physician's office prior to diagnosis; diabetic ketoacidosis was less frequent in patients who had siblings with T1DM and those diagnosed at the first appointment. Nausea and vomiting, abdominal pain, tachydyspnea, and altered level of consciousness were more common in the diabetic ketoacidosis group. There was no association with socioeconomic status, duration of symptoms before diagnosis, and length of the honeymoon period. Conclusions: Prospective studies are necessary to better define the impact of these factors on diagnosis and disease control. Campaigns to raise awareness among health professionals and the general population are essential to promote early diagnosis and proper treatment of diabetes mellitus in children and adolescents.
RESUMO Objetivo: Avaliar as variáveis associadas ao diagnóstico de diabetes melito tipo 1 (DM1) na vigência de cetoacidose diabética e seu impacto na evolução da doença. Métodos: Foram avaliadas 274 crianças e adolescentes com idade até 15 anos acompanhados em um ambulatório de endocrinologia pediátrica de um hospital universitário de Curitiba, Paraná, cuja primeira consulta ocorreu entre janeiro de 2005 e abril de 2015. Resultados: A maioria dos pacientes teve diagnóstico de DM1 na vigência de cetoacidose diabética. Os fatores associados foram: menor idade e maior número de consultas prévias ao diagnóstico; a cetoacidose diabética foi menos frequente quando havia um irmão com DM1 e quando o diagnóstico foi feito na primeira consulta médica. Náuseas ou vômitos, dor abdominal, taquidispneia e alteração do nível de consciência foram mais frequentes no grupo com cetoacidose diabética ao diagnóstico. Não se observou associação com nível socioeconômico, tempo de sintomas antes do diagnóstico e duração do período de lua de mel. Conclusões: São necessários estudos prospectivos para definir melhor o impacto desses fatores no diagnóstico e no controle da doença. Campanhas de conscientização dos profissionais de saúde e da população são necessárias para que haja diagnóstico precoce e tratamento adequado do diabetes melito em crianças e adolescentes.
