Type 1 diabetes care delivery in Yaoundé, Cameroon: Social and political representations

Background: Increasing chronic diseases challenges the health systems of low- and middleincome countries, including Cameroon. Type 1 diabetes (T1D), among the most common chronic diseases in children, poses particular care delivery challenges. Aim: We examined social representations of patients' roles and implementation of T1D care among political decision-makers, healthcare providers and patients within families. Setting: The study was conducted in Yaoundé, Cameroon. Methods: Eighty-two individuals were included in the study. The authors conducted semistructured interviews with policy makers (n = 5), healthcare professionals (n = 7) and patients 'parents (n = 20). Questionnaires were administered to paediatric patients with T1D (n = 50). The authors also observed care delivery at a referral hospital and at a T1D-focused nongovernmental organisation over 15 days. Data were analysed using thematic content analysis and descriptive statistics. Results: Cameroonian health policy portrays patients with T1D as passive recipients of care. While many practitioners recognised the complex social and economic determinants of adherence to T1D care, in practice interactions focused on specific biomedical issues and offered brief guidance. Cultural barriers and policy implementation challenges prevent patients and their families from being fully active participants in care. Parents and children prefer an ongoing relationship with a single clinician and interactions with other patients and families. Conclusion: Patients and families mobilise experience and lay knowledge to complement biomedical knowledge, but top-down policy and clinical practice limit their active engagement in T1D care. Contribution: Children with T1D and their families, policy makers, healthcare professionals, and civil society have new opportunities to contribute to person-centred care, as advocated by the Sustainable Development Goals.

Risk factors for ketoacidosis in children/adolescents with type 1 diabetes mellitus and establishment of a predictive model / 中国当代儿科杂志

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.

Sentimentos e desafios vivenciados pelo cuidador familiar da criança com diabetes mellitus tipo 1 / Feelings and challenges experienced by family caregivers of children with type 1 diabetes mellitus / Sentimientos y desafíos vividos por cuidadores familiares de niños con diabetes mellitus tipo 1

Objetivo: descrever as vivências e desafios do cuidador/familiar da criança com diabetes mellitus tipo 1. Método: estudo descritivo de abordagem qualitativa, junto a cuidadores de crianças com faixa etária de três a 12 anos incompletos, residentes em um município de Santa Catarina, Brasil. Os dados foram coletados entre julho e agosto de 2021, por meio de entrevistas em plataformas virtuais, e analisados conforme análise temática. Resultados: há vivências que transitam desde o medo e insegurança na descoberta do diagnóstico, dificuldades para aprender os cuidados com a criança, as mudanças de comportamentos de toda família, até preocupações com a criança no ambiente escolar, o que sobressai a importância das redes de apoio neste contexto, embora pouco mencionadas ou conhecidas pelos participantes. Considerações finais: as vivências e desafios do cuidador da criança com diabetes extrapola a esfera familiar, e indica que esse perfil de família necessita de acompanhamento mais próximo pelas equipes de saúde, na medida que isso garanta maior compreensão sobre a doença, cuidados necessários e referência de acolhimento.

Objective: to describe the experiences and challenges of the caregivers/family members of children with type 1 diabetes mellitus. Method: descriptive study with a qualitative approach, with caregivers of children aged between three and 12 years old, living in a municipality in Santa Catarina, Brazil. Data were collected between July and August 2021, through interviews on virtual platforms, and analyzed according to thematic analysis. Results: there are experiences that range from fear and insecurity when discovering the diagnosis, difficulties in learning how to care for the child, changes in the behavior of the entire family, to concerns about the child in the school environment, which highlights the importance of support networks in this context, although little mentioned or known by participants. Final considerations: the experiences and challenges of the caregiver of a child with diabetes go beyond the family sphere, and indicate that this family profile requires closer monitoring by health teams, as this guarantees greater understanding of the disease, necessary care and referral support.

Presencia de autoanticuerpos anti islotes pancreáticos en diabetes tipo 1 durante la edad pediátrica / Presence of anti-pancreatic islet autoantibodies in type 1 diabetes in children

En la Diabetes tipo 1 (DM1) la pérdida de células ß pancreáticas es consecuencia de un proceso de autoinmunidad que cursa con la presencia de autoanticuerpos anti-islotes pancreáticos (AAPs). Estos AAPs son marcadores útiles para la clasificación de la enfermedad. En un centro pediátrico de tercer nivel se analizó la frecuencia de presentación de GADA, IA-2A, ZnT8A e IAA en un grupo con reciente debut entre enero 2018 y agosto 2021 (n= 90). Además, se investigó la frecuencia de presentación y relación de los AAPs con la edad, sexo y tiempo de evolución en pacientes en seguimiento (n= 240). En el grupo de debut se obtuvo positividad de GADA, IA-2A, ZnT8A y IAA en 77,8; 60; 62 y 47,8% de los pacientes respectivamente, un 4% no presentó AAPs. El 95,6% de los pacientes presentaron al menos un AAPs positivo. La frecuencia de IAA en el grupo en debut fue mayor en menores de 5 años. En el grupo en seguimiento el 75,2% resultaron GADA positivo (85,7% en mujeres y 62,8% en varones) p<0,05. IA-2A y ZnT8A fueron positivos en 45 y 51.7% respectivamente. El 91% presentaron al menos un AAP positivo. En este grupo se evidenció una menor positividad en función del tiempo de evolución. Se pudo determinar la frecuencia de presentación de los AAPs en un grupo en debut y la relación con la edad, sexo y tiempo de evolución en pacientes en seguimiento. La determinación de APPs facilita la correcta clasificación y elección de la terapia adecuada (AU)

In type 1 diabetes (DM1) the loss of pancreatic ß-cells is a consequence of an autoimmune process that results in the presence of pancreatic anti-islet autoantibodies (PAAs). PAAs are useful markers for the classification of the disease. The frequency of presentation of GADA, IA-2A, ZnT8A, and IAA in a group with recent debut seen between January 2018 and August 2021 (n= 90) was analyzed in a tertiary pediatric center. In addition, we investigated the frequency of presentation and association of PAAs with age, sex, and time of evolution in patients in follow-up (n= 240). In the debut group, GADA, IA2A, ZnT8A, and IAA positivity was found in 77.8, 60, 62, and 47.8% of patients, respectively; no PAAs were observed in 4% of the patients. Overall, 95.6% presented at least one positive PAA. The frequency of IAA in the debut group was higher in children younger than 5 years. In the follow-up group, 75.2% were GADA positive (85.7% of females and 62.8% of males) p<0.05. IA-2A and ZnT8A were positive in 45 and 51.7% respectively. Ninety-one percent presented with at least one positive PAA. In this group, a lower positivity was evidenced as a function of the time of evolution. The frequency of presentation of PAAs in a debut group and the relationship with age, sex, and time of evolution in patients in follow-up was demonstrated. The assessment of PAAs facilitates the correct classification and choice of adequate therapy (AU)

O que crianças sabem sobre complicações agudas do diabetes? Insights para educação em diabetes / ¿Qué saben los niños sobre complicaciones agudas de diabetes? Perspectivas para la educación diabética / What children know about diabetes acute complications? Insights for diabetes education

Objective:to identify the knowledge and attitudes of school-agedchildren with diabetes facing acute complications.Method:exploratory study design with a qualitative approach, which used puppets as a data collection strategy. Children aged between seven and 12-years having experience with the disease for at least oneyear, followed-up at a Childhood Outpatient Clinic from Santa Catarina, Brazil, were interviewed. Analysis followed deductive content analysis. Results:participants demonstrated poor management of hyperglycemia episodes which could prevent diabetic ketoacidosis. The knowledge about hypoglycemia is higher due to its frequency; however, it has been the result of a deficient self-care with poor adult supervision. Conclusions:lack of understanding and inadequate management was evidenced, in especial, during the hyperglycemia and when the children are away from their parents. The nurses should promote education to immediate actions in acute complications. Educational materials focused on these clientele will contribute to enhance knowledge and abilities.

Introducción. La diabetes mellitus es una de las enfermedades crónicas con mayor prevalencia en la población pediátrica y juvenil, con efectos en la calidad de vida de los pacientes. Objetivo. Evaluar la calidad de vida de una población pediátrica menor de 18 años con diagnóstico de diabetes de tipo 1, de dos instituciones pediátricas de la ciudad de Bogotá. Materiales y métodos. Se recolectaron los datos sociodemográficos, y se emplearon la versión validada en español del cuestionario PedsQL 4.0™ y el módulo 3.2 sobre diabetes. Los datos se procesaron en el software estadístico STATA 17™. Resultados. Con el puntaje global del módulo 3.2 sobre diabetes, de la versión validada del PedsQL™, se evaluó la correlación entre los valores de la hemoglobina A1c (HbA1c) y los del cuestionario. Los pacientes con valores por debajo del 9 % de HbA1c presentaron una mejor calidad de vida relacionada con la salud, mientras que, en el grupo con HbA1c mayor de 9 %, se observó una baja percepción de calidad de vida (p=0,025). En cuanto el tipo de terapia y la relación con los dominios del PedsQL™ 3.2, versión diabetes, los pacientes que utilizaban la bomba de insulina o microinfusor presentaban mejor puntaje en los dominios barreras, cumplimiento, preocupación y comunicación, y en el puntaje global, respecto a quienes usaban múltiples inyecciones de insulina como tratamiento (p=0,0363). Conclusiones. En nuestros pacientes, un mejor control metabólico (medido por el valor de HbA1c) y el uso de microinfusora contribuyen a una percepción de mejor calidad de vida.

Introduction: Diabetes mellitus is one of the most prevalent chronic diseases in the pediatric and juvenile population that affects the quality of life of patients. Objective: To evaluate the quality of life of a pediatric population under 18 years of age diagnosed with type 1 diabetes from two pediatric institutions in the city of Bogotá. Materials and methods: We collected of sociodemographic data and clinical variables and application of the PedsQL 4.0™ questionnaire, and the diabetes module 3.2 version validated in Spanish. The sociodemographic data, the clinical variables and the PedsQL™ were processed in the statistical software Stata 17™. Results: In the global score of the PedsQL™ 3.2, diabetes version, men presented better quality of life compared to women. The correlation between the hemoglobin A1c (HbA1c) values and the PedsQL scale in the global score was evaluated. Patients with HbA1c values below 9% presented a better health-related quality of life, while in the group with HbA1c greater than 9% a perception of low quality of life was observed (p=0.025). Regarding the type of therapy and the relationship with the domains of the PedsQL 3.2, diabetes version, patients who used insulin pumps had better scores in the domains barriers, adherence, concern, communication and in the global score compared to patients who used multiple daily injections of insulin as treatment (p=0.0363). Conclusions: In our patients, a better metabolic control (measured by the HbA1c value) and the use of an insulin pump contribute to a better perception of quality of life.

Introducción: Según numerosos reportes, la pandemia por COVID­19 aumentó la incidencia de diabetes tipo 1 (DBT1) y cetoacidosis (CAD). Nuestro objetivo fue describir la frecuencia de nuevos casos de DBT1 y su severidad al ingreso en el Hospital J. P. Garrahan durante la pandemia, comparando con el periodo anterior. Material y métodos: Se realizó un estudio descriptivo, observacional, con análisis retrospectivo. Se incluyeron todos los nuevos casos entre 19/03/20- 31/12/21, comparados con el período 19/03/18-31/12/19. El diagnóstico de DBT1, CAD y su severidad se realizó según la International Society for Pediatric and Adolescent Diabetes. Se analizó el requerimiento de cuidados intensivos (UCI), presencia de COVID-19, hemoglobina glicosilada A1C (HbA1C) y autoanticuerpos (GADA, IAA, IA2, ZNT8). Se consideró significativa una p < 0,05. Resultados: En el período 2020-2021 se observó un incremento del 107% de nuevos casos, ingresando 56 pacientes con DBT1. La media y mediana de edad disminuyeron (8 vs 9,1 y 7,7 vs 10,4, respectivamente), con un incremento del 35% de menores de 5 años. Aumentó la frecuencia de CAD severa (41.1% vs 25.9%) y de requerimiento de UCI (17.9% vs 11.1%). La Hb A1C y la glucemia de ingreso mostraron incremento significativo (10.1% vs 12.32%, p<0.003 y 580 mg/dl ± 220 vs 490 mg/dl ± 188; p<0.05, respectivamente). Conclusión: En 2020-2021 se incrementó el número de nuevos casos de DBT1 en nuestra institución. Al ingreso hubo mayor proporción de niños pequeños y casos severos. Las dificultades de acceso a la consulta de atención primaria podrían relacionarse con nuestro hallazgo (AU)

Introduction: Numerous reports have shown that during the COVID-19 pandemic the incidence of type-1 diabetes (T1DB) and ketoacidosis (DKA) increased. The aim of this study was to describe the frequency of new cases and their severity on admission of T1DB at Hospital J. P. Garrahan during the pandemic, compared with the previous period. Material and methods: A descriptive, observational study with a retrospective analysis was conducted. All new cases seen between 19/03/20-31/12/21 were included and compared with the period 19/03/18-31/12/19. The diagnosis of T1DB, DKA, and its severity was made according to the International Society for Pediatric and Adolescent Diabetes. Intensive care (ICU) requirement, presence of COVID-19, glycosylated hemoglobin A1C (HbA1C), and autoantibodies (GADA, IAA, IA2, ZNT8) were analyzed. A p < 0.05 was considered significant. Results: In the period 2020-2021, a 107% increase in new cases was observed including 56 patients with T1DB. Mean and median age decreased (8 vs 9.1 and 7.7 vs 10.4, respectively), with a 35% increase in children under 5 years of age. The frequency of severe DKA (41.1% vs 25.9%) and ICU requirement (17.9% vs 11.1%) increased. Hb A1C and glycemia on admission also showed a significant increase (10.1% vs 12.32%, p<0.003 and 580 mg/dl ± 220 vs 490 mg/dl ± 188; p<0.05, respectively). Conclusion: In 2020-2021 an increase in the number of new cases of T1DB was observed at our institution. On admission, a higher rate of young children and severe cases was found. Difficulties to access primary care may have been related to our finding (AU)

Diabetes tipo 1 y Miastenia Gravis / Type-1 Diabetes and Myasthenia Gravis

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)

Psicologia e diabetes no Brasil: um mapeamento de profissionais e de suas ações / Psychology and diabetes in Brazil: the mapping of professionals and their practices / Psicología y diabetes en Brasil: un mapeo de los profesionales y sus acciones

Pouco se sabe sobre a atuação do psicólogo no Brasil junto a pessoas com Diabetes Mellitus. O objetivo desta pesquisa foi identificar os psicólogos brasileiros que trabalham com essa população e suas ações. Foram convidados a responder a um questionário online psicólogos que atuam ou atuaram junto a pessoas com diabetes. Participaram 79 psicólogos, principalmente da região Sudeste (59,5%). Todos declararam que haviam cursado pósgraduação. Na amostra, predominou o gênero feminino (89,9%), com idade entre 26 e 40 anos (46,8%). A maioria dos que atuam com diabetes declarou-se autônoma ou voluntária, e quase metade trabalhava menos do que 10 horas semanais. Entre aqueles que deixaram de trabalhar com diabetes, apenas uma minoria tinha vínculo empregatício. Além do trabalho com pessoas com diabetes, a maior parte declarou exercer outras atividades profissionais, como atendimentos clínicos em consultórios particulares, sugerindo que esta não é a atividade principal. Majoritariamente, os respondentes declararam não ter conhecimentos suficientes para o atendimento específico às pessoas com diabetes. Discute-se a qualidade da formação profissional dos psicólogos no Brasil, a necessidade de aprimoramento em relação à atuação com pessoas com diabetes e as condições de trabalho.(AU)

Little is known about the practice of psychologists in Brazil caring for people with Diabetes Mellitus. The aim of this research was to identify the Brazilian psychologists who work with this population and describe their actions. Psychologists who work or have worked with people diagnosed with diabetes were invited to answer an online questionnaire. The 79 participants lived mainly in the Southeast Region (59.5%). All of them declared to have a graduate degree, most were female (89.9%), aged 26 to 40 years (46.8%). Most of those working with diabetes declared to be autonomous or voluntary, and almost half had a workload of less than 10 hours a week. Among those who stopped working with diabetes, only a minority had a formal employment contract. In addition, most of them stated that they had other professional activities related to clinical care in private offices, suggesting that working with diabetes is not their main activity. Mostly, respondents stated that they did not have enough knowledge to care for people with diabetes. The quality of professional education of psychologists in Brazil, the need for specific improvement in labor relations and conditions were discussed.(AU)

Son escasas las informaciones del trabajo de los psicólogos en Brasil con las personas con Diabetes Mellitus. El objetivo de este estudio fue identificar los psicólogos brasileños que trabajan con esta población y describir sus acciones. Se invitó a psicólogos que trabajan o hayan trabajado con personas con diabetes a responder un cuestionario en línea. Participaron 79 psicólogos, principalmente de la región Sureste de Brasil (59,5%). Todos declararon tener posgrado.

Clinical and sociodemographic factors associated with the quality of life of children and adolescents with type 1 diabetes / Factores clínicos y sociodemográficos asociados a la calidad de vida de niños y adolescentes con diabetes tipo 1 / Fatores clínicos e sociodemográficos associados à qualidade de vida do público infantojuvenil com diabetes tipo 1

ABSTRACT Objective: To analyze clinical and sociodemographic factors associated with the health-related quality of life of children and adolescents with type 1 Diabetes Mellitus. Method: A quantitative, cross-sectional and analytical study, developed in a municipality in northeastern Brazil, between March and September 2021, with 81 children/adolescents with type 1 Diabetes Mellitus and their guardians/caregivers. A questionnaire containing sociodemographic and clinical variables and two quality of life instruments were used. Descriptive and inferential analysis was carried out. Results: Adolescents whose parents had a family income greater than a minimum wage had a lower prevalence of impaired quality of life when compared to those with a lower income. Adolescents with time since diagnosis of less than four years had a satisfactory quality of life, and children aged 8 to 12 years who self-administered insulin had a lower prevalence of high quality of life compared to those who did not. Conclusion: Adolescents with a family income of less than a minimum wage, diagnosis time of more than four years and children aged 8-12 who self-administer insulin need greater professional support to have a better quality of life.

RESUMEN Objetivo: Analizar los factores clínicos y sociodemográficos asociados a la calidad de vida relacionada con la salud de niños y adolescentes con Diabetes Mellitus tipo 1. Método: Estudio cuantitativo, transversal y analítico, desarrollado en un municipio del Nordeste brasileño, entre marzo y septiembre de 2021, con 81 niños/adolescentes con Diabetes Mellitus tipo 1 y sus tutores/cuidadores. Se utilizó un cuestionario que contenía variables sociodemográficas y clínicas y dos instrumentos de calidad de vida. Se realizó análisis descriptivo e inferencial. Resultados: los adolescentes cuyos padres tenían un ingreso familiar superior a un salario mínimo tuvieron una menor prevalencia de deterioro de la calidad de vida en comparación con aquellos con menores ingresos. Los adolescentes con un tiempo de diagnóstico menor a cuatro años tuvieron una calidad de vida satisfactoria, y los niños de 8 a 12 años que se autoadministraron insulina tuvieron una menor prevalencia de alta calidad de vida en comparación con los que no lo hicieron. Conclusión: Los adolescentes con ingreso familiar menor a un salario mínimo, tiempo de diagnóstico mayor a cuatro años y niños de 8 a 12 años que se autoadministran insulina necesitan mayor apoyo profesional para tener una mejor calidad de vida.

Adolescentes com tempo de diagnóstico menor que quatro anos apresentaram qualidade de vida satisfatória, e crianças de 8 a 12 anos que faziam autoaplicação de insulina apresentaram prevalência menor de qualidade de vida alta em relação às que não realizavam. Conclusão: Adolescentes com renda familiar inferior a um salário mínimo, tempo de diagnóstico superior a quatro anos e crianças de 8-12 anos que realizam autoaplicação de insulina necessitam de maior suporte profissional para ter melhor qualidade de vida.

Association between glycemic control in different emotional conditions and adherence to carbohydrate counting in people with type 1 diabetes during the COVID-19 pandemic in Brazil / Associação entre controle glicêmico em diferentes condições emocionais e adesão à contagem de carboidratos em pessoas com diabetes tipo 1 durante a pandemia de COVID-19 no Brasil

ABSTRACT Objective Evaluate the association between glycemic control in different emotional perceptions and the adherence to carbohydrate counting by adults with type 1 diabetes during the COVID-19 pandemic in Brazil. Methods This cross-sectional, descriptive, and analytical study was approved by the Research Ethics Committee (Opinion nº 4,147,663) and conducted in July 2020 using a Google Forms® form. Socioeconomic and demographic data were collected; glycemic monitoring according to the individuals' emotions at the time of measurement (happy, motivated, or hopeful; stressed or anxious; sad, distressed, or with depressive symptoms); data on adherence to carbohydrate counting and social distancing. Pearson's Chi-Square test was applied with adjusted residual analysis (p<0.05). Results Approximately 64.62% of the 472 participants, had hyperglycemia when stressed/anxious, and 52.97% when they felt sad/distressed/depressive (p<0.000). Associations were observed between having normoglycemia in any emotional situation and performing the carbohydrate counting (p<0.000); perceiving oneself as happy/motivated/hopeful and having hyperglycemia, and not measuring blood glucose was associated with not having the carbohydrate counting (p<0.000); being stressed or anxious was associated with not measuring blood glucose and not having the carbohydrate counting (p<0.000). Conclusion The need for multidisciplinary care to enhance mental health and adherence to treatment for people with type 1 diabetes is highlighted.

RESUMO Objetivo O estudo objetivou avaliar a associação entre o controle glicêmico em diferentes percepções emocionais e a adesão à contagem de carboidratos por adultos com diabetes tipo 1 durante a pandemia de COVID-19 no Brasil. Métodos Trata-se de um estudo transversal, descritivo e analítico aprovado pelo Comitê de Ética em Pesquisa (Parecer 4.147.663), realizado em julho de 2020 por meio de formulário Google Forms®. Foram coletados dados socioeconômicos e demográficos; monitoramento glicêmico de acordo com as emoções do indivíduo no momento da mensuração (feliz, motivado ou esperançoso; estressado ou ansioso; triste, angustiado ou com sintomas depressivos); dados sobre adesão à contagem de carboidratos e distanciamento social. Aplicou-se o teste qui-quadrado de Pearson com análise residual ajustada (p<0,05). Resultados Dos 472 participantes, 64,62% apresentavam hiperglicemia quando estressados/ansiosos, e 52,97%, quando se sentiam tristes/angustiados/depressivos (p<0,000). Foram observadas associações entre ter normoglicemia em qualquer situação emocional e realizar a contagem de carboidratos (p<0,000), perceber-se feliz/motivado/esperançoso e ter hiperglicemia, assim como não medir a glicemia foi associado a não ter a contagem de carboidratos (p<0,000). Estar estressado ou ansioso foi associado a não medir a glicemia e não ter a contagem de carboidratos (p<0,000). Conclusão Destaca-se a necessidade de atendimento multidisciplinar para potencializar a saúde mental e a adesão ao tratamento de pessoas com diabetes tipo 1.

Alveolar and mandibular cortex bone status in individuals with type 1 diabetes mellitus: a cross-sectional paired study / Condição óssea alveolar e da cortical mandibular em indivíduos com diabetes mellitus tipo 1: um estudo transversal pareado

Aim: This study compared alveolar bone loss, teeth with furcation, and mandibular cortical modification between individuals with type 1 diabetes mellitus (T1DM) and nondiabetic individuals. Methods: Radiographs of 50 T1DM individuals and 100 nondiabetic individuals were examined to evaluate the presence of teeth with furcation, alveolar bone loss, and mandibular cortical modifications. The Mann-Whitney, Chi-square, and Student's t tests were used to analyze personal characteristics and bone status. Linear and logistic regression was performed to explore associations. Results: A significant difference was observed in the average number of teeth with furcation and in the median of alveolar bone loss between T1DM and the nondiabetic participants. T1DM individuals are more likely to have alveolar bone loss (OR = 3 2.250), teeth with furcation (OR = 8.903), and mandibular cortical modification (OR = 15.667) than are nondiabetic individuals. Among T1DM individuals, the glycemic control has a high influence in mandibular cortical modifications (p < 0.05). Conclusions: A high association between uncontrolled blood glucose and mandibular cortical modifications was observed among T1DM individuals. Alveolar bone loss of T1DM individuals was associated with age, time of diagnosis, glycemic control, and the existence of chronic complications.

Objetivo:Comparar a perda óssea alveolar, a presença de dentes com lesão de furca e a alteração da cortical óssea entre indivíduos com DMT1 e indivíduos não-diabéticos. Métodos: Foram examinadas radiografias de 50 indivíduos diabéticos e de 100 não-diabéticos para avaliar a presença de dentes com lesão de furca, perda óssea alveolar e alteração cortical mandibular. Para analisar as características individuais e as condições ósseas foram usados os testes de Mann-Whitney,Qui-quadrado e t de Student. Regressões linear e logística foram realizadas para identificar associações. Resultados: Foi encontrada diferença significativa na média de dentes com lesão de furca e na mediana da perda óssea alveolar entre diabéticos e não-diabéticos. Indivíduos com DMT1 possuem mais chance de apresentar perda óssea alveolar (OR = 32,250), lesão de furca (OR=8,903) e alteração da cortical mandibular (OR = 15,667) em comparação aos indivíduos não-diabéticos. Entre os diabéticos, o controle da glicemia possui grande influência nas alterações da cortical mandibular (p < 0,05). Conclusões: Existe uma alta associação entre os níveis de glicemia descontrolada e alterações na cortical mandibular entre os indivíduos com DMT1. A perda óssea alveolar de indivíduos com DMT1 foi associada aos fatores idade, tempo de diagnóstico, controle da glicemia e a presença de complicações crônicas.

Production and antigenicity analysis of a recombinant insulinoma associated protein-2 in HEK293 cells / 生物工程学报

Insulinoma-associated protein-2 (IA-2) is a transmembrane glycoprotein belonging to the tyrosine phosphatase-like protein family as well as an important autoantigen in the diagnosis of type 1 diabetes. IA-2 products have been marketed in Europe and the United States. At present, commercially available IA-2 antigens are either the recombinant IA-2ic domain or the IA-2 naturally extracted from bovine islets. However, the recombinant IA-2 antigen displays weak positive in clinic practice, which often results in occasional detection failures, thus cannot completely replace the naturally extracted IA-2 antigen. In this study, an HEK293 expression system was used to explore the production of recombinant IA-2. An IA-2 transmembrane fragment (IA-2 TMF) located at amino acid position 449-979, also known as the natural membrane protein form of IA-2, was produced in HEK293 through transfection, and both the expression conditions and dissolution conditions of the membrane protein were also optimized. The purified membrane protein yield was 0.78 mg/L cell culture. Subsequently, the antigen activity of IA-2 TMF was compared with RSR rhIA-2 through enzyme linked immunosorbent assay. The serum of 77 type 1 diabetes patients and 32 healthy volunteers were detected. Receiver operating characteristic curve (ROC) curve was used to characterize the sensitivity and specificity of the test results. The results showed that the sensitivity of IA-2 TMF was 71.4% (55/77), while the sensitivity of RSR rhIA-2 was 63.6% (49/77), and the specificity of both antigens were all 100%. There was no significant difference in specificity between the two antigens, but the sensitivity of IA-2 TMF was appreciably better than that of the imported gold standard RSR rhIA-2 antigen. In conclusion, the recombinant IA-2 TMF produced in HEK293 cells can be used as a raw material to develop in vitro diagnostic reagents for type 1 diabetes.

Behavioural and emotional problems in Malaysian children and adolescents with type 1 diabetes mellitus: A cross-sectional study in a single centre / Journal of the ASEAN Federation of Endocrine Societies

Introduction@#Type 1 diabetes mellitus (T1DM) is an autoimmune disorder that requires a lifelong treatment regimen which may affect psychosocial development.@*Objective@#To identify behavioural and emotional problems in children and adolescents with T1DM.@*Methodology@#A cross-sectional study using the Child Behaviour Check List (CBCL) was conducted among all T1DM patients receiving treatment at the Paediatric Endocrine Unit, Hospital Tunku Azizah Kuala Lumpur, Malaysia.@*Results@#Forty T1DM patients were included. The mean age of the participants was 12.4 years (SD=2.69), with 52.5% males, and 75% Malay. The average duration of illness was 4.8 years, 9 were pre-pubertal, while mean HbA1c was 9.4%. Thirty-five percent of the respondents had parent-reported internalizing problems and 17.5% had parent-reported externalizing problems. Those >12 years old had more internalizing problems (p=0.004) compared to those ≤12 years old. The differences were in the anxious/depressed syndrome subscale (p=0.001) and withdrawn/depressed syndrome subscale (p=0.015). There were no statistically significant differences in the 3 main global scores by gender, glycaemic control, duration of illness and pubertal status by univariate analysis.@*Conclusion@#T1DM patients >12 years old were at higher risk of developing psychosocial difficulties. This highlighted the benefit of screening of behavioural and emotional issues in children and adolescents with T1DM.

Characteristics of children with newly diagnosed type 1 diabetes mellitus in Brunei Darussalam / Journal of the ASEAN Federation of Endocrine Societies

Objective@#This study aims to characterize the presentation, biochemical status of children with T1DM at diagnosis, the type of subcutaneous insulin regimens initiated, and to determine the incidence of T1DM in Bruneian children aged 18 years and younger.@*Methodology@#A retrospective electronic and paper medical chart review was performed on patients aged 18 years and younger diagnosed with T1DM from 2013 to 2018 in Brunei Darussalam.@*Results@#A total of 31 children with a mean age of 10.2 ± 3.6 years old were diagnosed with T1DM, of which 66.7% presented with diabetic ketoacidosis (DKA), a majority in severe DKA with an intercurrent illness (p=0.021). The mean HbA1c was 13.6 ± 2.7% with a mean serum glucose of 37.0±14.9 mmol/L at diagnosis. In the majority of the children (67.7%), multiple daily injections of subcutaneous insulin were initiated. The incidence of T1DM in children aged 18 years and younger was 4.9 per 100,000 for the year 2018.@*Conclusions@#The majority of the patients in this study presented with severe DKA with an intercurrent illness. This highlights the importance of childhood T1DM awareness among the public and healthcare providers. The incidence of childhood T1DM in Brunei Darussalam is similar to other countries in the Asian region, being relatively low, compared to the rest of the world.

Diabetes mellitus and adverse outcomes after carotid endarterectomy: A systematic review and meta-analysis / 中华医学杂志(英文版)

BACKGROUND@#There is still uncertainty regarding whether diabetes mellitus (DM) can adversely affect patients undergoing carotid endarterectomy (CEA) for carotid stenosis. The aim of the study was to assess the adverse impact of DM on patients with carotid stenosis treated by CEA.@*METHODS@#Eligible studies published between 1 January 2000 and 30 March 2023 were selected from the PubMed, EMBASE, Web of Science, CENTRAL, and ClinicalTrials databases. The short-term and long-term outcomes of major adverse events (MAEs), death, stroke, the composite outcomes of death/stroke, and myocardial infarction (MI) were collected to calculate the pooled effect sizes (ESs), 95% confidence intervals (CIs), and prevalence of adverse outcomes. Subgroup analysis by asymptomatic/symptomatic carotid stenosis and insulin/noninsulin-dependent DM was performed.@*RESULTS@#A total of 19 studies (n = 122,003) were included. Regarding the short-term outcomes, DM was associated with increased risks of MAEs (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 5.1%), death/stroke (ES = 1.61, 95% CI: [1.13-2.28], prevalence = 2.3%), stroke (ES = 1.55, 95% CI: [1.16-1.55], prevalence = 3.5%), death (ES = 1.70, 95% CI: [1.25-2.31], prevalence =1.2%), and MI (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 1.4%). DM was associated with increased risks of long-term MAEs (ES = 1.24, 95% CI: [1.04-1.49], prevalence = 12.2%). In the subgroup analysis, DM was associated with an increased risk of short-term MAEs, death/stroke, stroke, and MI in asymptomatic patients undergoing CEA and with only short-term MAEs in the symptomatic patients. Both insulin- and noninsulin-dependent DM patients had an increased risk of short-term and long-term MAEs, and insulin-dependent DM was also associated with the short-term risk of death/stroke, death, and MI.@*CONCLUSIONS@#In patients with carotid stenosis treated by CEA, DM is associated with short-term and long-term MAEs. DM may have a greater impact on adverse outcomes in asymptomatic patients after CEA. Insulin-dependent DM may have a more significant impact on post-CEA adverse outcomes than noninsulin-dependent DM. Whether DM management could reduce the risk of adverse outcomes after CEA requires further investigation.
