Use of FGF21 analogs for the treatment of metabolic disorders: a systematic review and meta-analysis

ABSTRACT FGF21 is a hormone produced primarily by the liver with several metabolic functions, such as induction of heat production, control of glucose homeostasis, and regulation of blood lipid levels. Due to these actions, several laboratories have developed FGF21 analogs to treat patients with metabolic disorders such as obesity and diabetes. Here, we performed a systematic review and meta-analysis of randomized controlled trials that used FGF21 analogs and analyzed metabolic outcomes. Our search yielded 236 articles, and we included eight randomized clinical trials in the meta-analysis. The use of FGF21 analogs exhibited no effect on fasting blood glucose, glycated hemoglobin, HOMA index, blood free fatty acids or systolic blood pressure. However, the treatment significantly reduced fasting insulinemia, body weight and total cholesterolemia. None of the included studies were at high risk of bias. The quality of the evidence ranged from moderate to very low, especially due to imprecision and indirection issues. These results indicate that FGF21 analogs can potentially treat metabolic syndrome. However, more clinical trials are needed to increase the quality of evidence and confirm the effects seen thus far.

Use of probiotics and similar in pediatric patients with Type 1 Diabetes Mellitus: a systematic review / Uso de probióticos e similares em pacientes pediátricos com Diabetes Mellitus tipo 1: uma revisão sistemática

ABSTRACT Objective: To perform a systematic review of randomized controlled trials, evaluating the effect of probiotics, prebiotics or symbiotics supplementation on glycemic and inflammatory control in children with Type 1 Diabetes Mellitus (T1DM). Data source: The Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Clinical Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SciELO) databases were searched. Randomized clinical trials of pediatric patients with DM1 using probiotics, prebiotics or symbiotics were included, regardless of year or language of publication. Studies that did not evaluate glycated hemoglobin (HbA1c) were excluded. Metabolic results (HbA1c, total insulin dose and C-peptide) and inflammatory control [interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ)] during probiotic supplementation or similar, related to modification of the intestinal microbiota, were analyzed. PROSPERO ID: CRD42022384485. Data synthesis: Five studies were selected for a systematic review. Regarding metabolic markers, only one of the articles that analyzed HbA1c showed a significant decrease (p=0.03) in the intervention group. One study identified a reduction in the total dose of insulin and increased C-peptide levels. Regarding the evaluation of inflammatory parameters (IL-10, TNF-α, INF-γ), there were no statistical relevant modifications. Conclusions: Current data from the literature were not conclusive in identifying an improvement in glycemic control and did not observe changes in inflammatory parameters with the use of probiotics, prebiotics or symbiotics in pediatric patients with T1DM.

RESUMO Objetivo: Realizar uma revisão sistemática de ensaios clínicos randomizados controlados avaliando o efeito da suplementação de probióticos, prebióticos ou simbióticos no controle glicêmico e inflamatório em crianças com diabetes mellitus tipo 1 (DM1). Fontes de dados: As bases Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Clinical Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Scientific Electronic Library Online (SciELO) foram pesquisadas. Foram incluídos ensaios clínicos randomizados de pacientes pediátricos com DM1 em uso de probióticos, prebióticos ou simbióticos, independentemente de ano ou idioma de publicação. Foram excluídos os trabalhos que não avaliaram hemoglobina glicada (HbA1c). Os resultados metabólicos (HbA1c, dose de insulina total e peptídeo C) e o controle inflamatório [interleucina-10 — IL-10), fator de necrose tumoral-alfa (TNF-α) e interferon-gama (IFN-γ)] durante a suplementação de probióticos ou similares, relacionados à modificação da microbiota intestinal, foram analisados. ID PROSPERO: CRD42022384485. Síntese dos dados: Cinco estudos foram selecionados para revisão sistemática. Com relação aos marcadores metabólicos, apenas um dos artigos que analisaram a HbA1c apresentou diminuição significativa (p=0,03) no grupo intervenção. Um estudo identificou redução da dose total de insulina e aumento dos níveis de peptídeo C. Quanto à avaliação dos parâmetros inflamatórios (IL-10, TNF-α, INF-γ), não houve modificações de relevância estatística. Conclusões: Os dados atuais da literatura não foram conclusivos em identificar melhora no controle glicêmico e não observaram mudanças nos parâmetros inflamatórios com o uso de probióticos, prebióticos ou simbióticos em pacientes pediátricos com DM1.

Objective: to analyze the correlation between time on target and glycated hemoglobin in people living with diabetes mellitus and carrying out continuous blood glucose monitoring or self-monitoring of capillary blood glucose. Method: systematic review of etiology and risk based on JBI guidelines and reported according to Preferred Reporting Items for Systematic Reviews and Meta- Analyses, covering six databases and grey literature. The sample included 16 studies and methodological quality was assessed using JBI tools. Protocol registered in the Open Science Framework, available at https://doi.org/10.17605/OSF.IO/NKMZB. Results: time on target (70-180 mg/dl) showed a negative correlation with glycated hemoglobin, while time above target (>180 mg/dl) showed a positive correlation. Correlation coefficients ranged between -0.310 and -0.869 for time on target, and between 0.66 and 0.934 for time above target. A study was carried out on a population that performed self-monitoring. Conclusion: there is a statistically significant correlation between time on target and time above target with glycated hemoglobin. The higher the proportion in the adequate glycemic range, the closer to or less than 7% the glycated hemoglobin will be. More studies are needed to evaluate this metric with data from self-monitoring of blood glucose.

Effect of megaloblastic anemia on hemoglobin A2 and diagnosis of ?-thalassemia trait

Context: ?-thalassemia trait is usually diagnosed by raised hemoglobin A2 (HbA2). The presence of megaloblastic anemia can cause an increase in HbA2 and create a diagnostic dilemma. Here, we have analyzed the effect of vitamin B12 and folic acid supplementation on HbA2 and diagnosis of ?-thalassemia trait in cases of megaloblastic anemia with raised HbA2. Materials and Methods: Cases of megaloblastic anemia with raised HbA2 on high-performance liquid chromatography (HPLC) were supplemented with vitamin B12 and folic acid. Post-treatment evaluation was done after 2 months. Cases showing adequate hematological response were subjected to statistical analysis. Based on post-treatment HbA2 value, the cases were diagnosed as normal, borderline raised HbA2, or ?-thalassemia trait. Pre- and post-treatment values of red cell parameters and HbA2 were analyzed. Results: There was a significant decrease in HbA2 value after vitamin B12 and folic acid supplementation. The diagnosis was changed in 70.97% of the cases after treatment. The chance of inconclusive diagnosis was decreased from more than 50% to less than 10%. Pre-treatment mean corpuscular volume (MCV) and HbA2% showed a significant difference between the thalassemic and normal groups. Conclusions: Megaloblastic anemia can lead to false-positive diagnosis of ?-thalassemia trait on HPLC. Repeat HPLC should be done after adequate supplementation of vitamin B12 and folic acid in cases of megaloblastic anemia with raised HbA2. Red cell parameters are not helpful to suspect ?-thalassemia trait in presence of megaloblastic anemia. However, HbA2% on HPLC can be a useful parameter to suspect or exclude ?-thalassemia trait in cases of megaloblastic anemia.

Retinopatía diabética y su relación con los niveles de hemoglobina glucosilada / Diabetic Retinopathy and its Relationship with Glycosylated Hemoglobin Levels

Introducción: La retinopatía diabética es la principal causa de ceguera en personas diabéticas de 20 a 64 años de edad, e incrementa su aparición frente a un mal control de la enfermedad, que se expresa con valores altos de hemoglobina glucosilada (HbA1C). Objetivo: Establecer la relación entre los niveles de hemoglobina glucosilada y la presencia de retinopatía en los pacientes con diabetes mellitus tipo 2. Métodos: Se llevó a cabo un estudio descriptivo, prospectivo y transversal, en el que se obtuvieron, mediante ficha de observación, datos sociodemográficos, de evaluación oftalmológica y niveles de HbA1C, de los pacientes atendidos en consulta externa del Hospital General Isidro Ayora de la ciudad de Loja, Ecuador, en el período febrero-junio de 2018. Se aplicaron medidas de frecuencia y asociación para el análisis estadístico. Resultados: Se incluyeron 160 pacientes: 108 mujeres y 52 hombres, todos de raza mestiza. Se identificó retinopatía en 26,8 por ciento (N = 43) de los pacientes, de quienes 41 por ciento (N = 18) tenía más de 65 años de edad. La media de HbA1C en pacientes sin retinopatía fue de 7,4 por ciento, y en aquellos con retinopatía de 9,8 por ciento en mayor porcentaje de pacientes con valores de HbA1C de 7 por ciento o más presentaron retinopatía diabética, en comparación con aquellos de HbA1C menores a 7 por ciento (p < 0,0001), la retinopatía no proliferativa moderada fue el principal diagnóstico realizado. Conclusiones: El mal control glucémico en las personas con diabetes mellitus tipo 2 se asocia con mayor probabilidad de aparición de lesiones retinianas(AU)

Introduction: Diabetic retinopathy is the main cause of blindness in diabetic people aged 20 to 64 years; it increases its occurrence due to poor control of the disease, expressed by high values of glycosylated hemoglobin (HbA1c). Objective: To establish the relationship between glycosylated hemoglobin levels and the presence of retinopathy in patients with type 2 diabetes mellitus. Methods: A descriptive, prospective and cross-sectional study was carried out, in which sociodemographic data, others from an ophthalmologic evaluation and HbA1c levels were obtained, by means of an observation card, from patients seen in the outpatient clinic of Hospital General Isidro Ayoraof the city of Loja, Ecuador, in the period February-June 2018. Frequency and association measures were applied for statistical analysis. Results: The study included 160 patients: 108 women and 52 men, all of mixed race. Retinopathy was identified in 26.8percent (N=43) of patients, of whom 41percent (N=18) were over 65 years of age. The mean HbA1c in patients without retinopathy was 7.4percent, and 9.8percent in those with retinopathy. A higher percentage of patients with HbA1c values of 7percent more had diabetic retinopathy, compared to those with HbA1C under 7percent (p<0.0001). Moderate nonproliferative retinopathy was the main diagnosis. Conclusions: Poor glycemic control in persons with type 2 diabetes mellitus is associated with increased likelihood of retinal lesions(AU)

Correlación entre la glucosa salival con la glucosa de ayuno, la Hemoglobina glicada y el Péptido-C en personas con diabetes mellitus tipo 2

Objetivo : Determinar la correlación entre la glucosa salival con la glucosa en ayunas, HbA1c y el péptido C en personas con Diabetes Mellitus tipo 2 (DM2). Materiales y métodos : Estudio transversal llevado a cabo en el Centro de Investigación en Diabetes, Obesidad y Nutrición (CIDON) en Lima, Perú durante el año 2021. Se categorizó en buen control metabólico (HbA1c<7 %) y mal control metabólico (HbA1c≥7 %). Se midió la glucosa basal, HbA1c y el péptido C en sangre. La glucosa salival se midió con el método glucosa oxidasa. La correlación de Spearman fue usada para determinar la asociación entre la glucosa salival con la glucosa en ayunas, HbA1c y el péptido- C. Resultados : Participaron un total de 142 personas con DM2. La concentración de glucosa salival fue significativamente más elevada en DM2 con mal control metabólico (p<0.01). Se observó una correlación positiva débil significativa entre la glucosa salival y la glucosa basal (r=0.23, p=0.04) y HbA1c (r=0.26, p=0.02) en DM2 con mal control metabólico y una correlación negativa insignificante (r=-0.08; p=0.47) con el péptido C. Conclusiones : La glucosa salival presenta una asociación significativa y positiva con la glucosa en sangre y la HbA1c, pero no con el péptido C en personas con DM2 con mal control metabólico. Sin embargo, hay muchos factores que deben ser considerados y analizados más a fondo para determinar su posible uso.

Objetivo : To determine the correlation between salivary glucose levels with fasting blood glucose, HbA1c, and C-peptide in patients with type 2 diabetes mellitus (T2DM). Materials and methods : This is a cross-sectional study performed at the Centro de Investigación en Diabetes, Obesidad y Nutrición (CIDON) in Lima, Peru, during 2021. Patients were categorized as those with good metabolic control (HbA1c<7 %), and poor metabolic control (HbA1c≥7 %). Baseline fasting blood glucose, as well as blood HbA1c and C-peptide values were measured. Salivary glucose was measured using the glucose oxidase method. Spearman's correlation was used for determining an association between salivary glucose levels and fasting blood glucose, HbA1c, and C-peptide. Results : One-hundred and forty-two subjects with T2DM participated in the study. Salivary glucose was significantly higher in T2DM subjects with poor metabolic control (p<0.01). A weak positive correlation between salivary glucose and fasting blood glucose (r= 0.23, p= 0.04) and HbA1c (r= 0.26, p= 0.02) was observed in subjects with T2DM and poor metabolic control, and also a non-significant negative correlation (r=-0.08; p= 0.47) with C-peptide. Conclusions : Salivary glucose levels show significant and positive association with fasting blood glucose and HbA1c, but not with C-peptide in persons with T2DM and poor metabolic control. However, there are many factors that should be considered and analyzed in detail aiming to determine its potential use.

Opiniones y recomendaciones de la Sociedad Argentina de Diabetes. Hemoglobina A1c / Opinions and recommendations of the Argentine Diabetes Society. Hemoglobin A1c

La estandarización de la hemoglobina A1c (HbA1c) permitió en algunos países su uso para el diagnóstico de la diabetes mellitus (DM) y la prediabetes, además de su empleo en el seguimiento del paciente con DM. Es importante recordar que se trata de una medida indirecta del promedio glucémico durante el tiempo de vida media del eritrocito, pudiendo verse afectada por variables no glucémicas, como también por interferencias analíticas según la metodología empleada para su determinación. A continuación, se describen las recomendaciones y consideraciones a tener en cuenta para la determinación de la HbA1c cuando se emplea como criterio diagnóstico de la DM, teniendo en cuenta que al utilizarla para tal fin es necesario que la medida se realice con métodos certificados y estandarizados al ensayo utilizado en el Diabetes Control and Complications Trial (DCCT).

The standardization of hemoglobin A1c (HbA1c) allowed in some countries its use for the diagnosis of diabetes mellitus (DM) and prediabetes, in addition to its use in the follow-up of patients with DM. It is important to highlight that it is an indirect measurement of the glycemic average during the halflife of the erythrocyte, and may be affected by non-glycemic variables, as well as by analytical interferences depending on the methodology used for its determination. The recommendations and considerations to take into account for the determination of HbA1c when it is used as a diagnostic criterion for diabetes are described below. In addition, it is important to emphasize that it is essential that the HbA1c measurement be performed with certified and standardized methods to the Diabetes Control and Complications Trial (DCCT)results.

Once-Weekly Insulin Icodec vs. Once-Daily Insulin Glargine U100 for type 2 diabetes: a systematic review and meta-analysis of phase 2 randomized controlled trials

ABSTRACT Objective: Insulin Icodec is a novel basal insulin analogue designed for once-weekly administration, therefore might propitiate reduction in the frequency of injections and facilitate treatment adherence. This study aimed to determine the glycemic control and safety profile of Insulin Icodec, compared with Glargine U100 in patients with diabetes mellitus type 2. Materials and methods: We performed a systematic review and meta-analysis of randomized controlled trials (RCT) data comparing Once-Weekly Insulin Icodec and Once-Daily Insulin Glargine U100 in patients with type 2 diabetes mellitus. PubMed, Embase, and Cochrane databases were searched for trials published up to May 14, 2022. Data were extracted from published reports and quality assessment was performed per Cochrane recommendations. Results: Three studies were included comprising 453 patients, 230 (50.77%) using Once-Weekly Insulin Icodec and 223 (49.22%) using Once-Daily Insulin Glargine U100. In the pooled data, Glycated Hemoglobin (MD -0.20% CI -0.33 to -0.07%; P=0.002) change from baseline demonstrated a significantly higher reduction in the Icodec group. Time with Glucose in Range (MD 6.60% CI 3.63 to 9.57%; P < 0.0001) and Insulin Dose Difference (MD 0.97UI CI 0.76 to 1.18UI; P < 0.0001) were higher in the Icodec group. There was no significant difference in fasting plasma glucose, body weight change, hypoglycemia or any adverse event evaluated. Conclusions: Once-Weekly Insulin Icodec was associated with a small reduction in Glycated Hemoglobin, as well as higher Time with Glucose in Range, with similar hypoglycemic adverse events, when compared with Once-Daily Insulin Glargine U100.

Resultados Imediatos após Múltiplos Enxertos Arteriais em Cirurgia de Revascularização Miocárdica no Estado de São Paulo: Estudo de Coorte / Immediate Results after Multiple Arterial Grafts in Coronary Artery Bypass Graft Surgery in the São Paulo State: Cross Cohort Study

Resumo Fundamento Os resultados a curto prazo após o uso de enxertos arteriais ainda suscitam questionamentos e dúvidas na sociedade médica. Objetivo Comparar os resultados imediatos de pacientes submetidos à cirurgia de revascularização do miocárdio com enxerto arterial único versus enxertos arteriais múltiplos. Métodos Estudo de coorte transversal no Registro Paulista de Cirurgia Cardiovascular II (REPLICCAR II). Os dados perioperatórios de 3122 pacientes foram agrupados pelo número de enxertos arteriais utilizados e seus desfechos foram comparados: reoperação, infecção profunda da ferida torácica (IPFT), acidente vascular cerebral, lesão renal aguda, intubação prolongada (>24 horas), tempo de internação curta (<6 dias), tempo de internação prolongada (>14 dias), morbidade e mortalidade. O Propensity Score Matching (PSM) correspondeu a 1062 pacientes, ajustado para o risco de mortalidade. Resultados Após PSM, o grupo enxerto arterial único apresentou pacientes com idade avançada, mais ex-fumantes, hipertensos, diabéticos, portadores de angina estável e infarto do miocárdio prévio. Nos enxertos arteriais múltiplos houve predomínio do sexo masculino, pneumonia recente e cirurgias de urgência. Após o procedimento, houve maior incidência de derrame pleural (p=0,042), pneumonia (p=0,01), reintubação (p=0,006), IPFT (p=0,007) e desbridamento esternal (p=0,015) no grupo de enxertos multiarteriais, porém, menor necessidade de hemotransfusão (p=0,005), infecções de extremidades (p=0,002) e menor tempo de internação (p=0,036). O uso bilateral da artéria torácica interna não foi relacionado ao aumento da taxa de IPFT, e sim a hemoglobina glicosilada >6,40% (p=0,048). Conclusão Pacientes submetidos a técnica multiarterial apresentaram maior incidência de complicações pulmonares e IPFT, sendo que a hemoglobina glicosilada ≥6,40% teve maior influência no resultado infeccioso do que a escolha dos enxertos.

Abstract Background The short-term results after using arterial grafts still raise questions and doubts for medical society. Objective To compare the immediate outcomes of patients undergoing single arterial graft versus multiple arterial grafts coronary artery bypass grafting surgery. Methods Cross-sectional cohort study in the São Paulo Registry of Cardiovascular Surgery II (REPLICCAR II). Perioperative data from 3122 patients were grouped by the number of arterial grafts used, and their outcomes were compared: reoperation, deep sternal wound infection (DSWI), stroke, acute kidney injury, prolonged intubation (>24 hours), short hospital stay (<6 days), prolonged hospital stay (>14 days), morbidity and mortality. Propensity Score Matching (PSM) matched 1062 patients, adjusted for the mortality risk. Results After PSM, the single arterial graft group showed patients with advanced age, more former smokers, hypertension, diabetes, stable angina, and previous myocardial infarction. In the multiple arterial grafts, there was a predominance of males, recent pneumonia, and urgent surgeries. After the procedure, there was a higher incidence of pleural effusion (p=0.042), pneumonia (p=0.01), reintubation (p=0.006), DSWI (p=0.007), and sternal debridement (p=0.015) in the multiple arterial grafts group, however, less need for blood transfusion (p=0.005), extremity infections (p=0.002) and shorter hospital stays (p=0.036). Bilateral use of the internal thoracic artery was not related to increased DSWI rate, but glycosylated hemoglobin >6.40% (p=0.048). Conclusion Patients undergoing the multiarterial technique had a higher incidence of pulmonary complications, and DSWI, where glycosylated hemoglobin ≥6.40%, had a greater influence on the infectious outcome than the choice of grafts.

Risk analysis of blood glucose variation in type 2 diabetic STEMI patients with different HbA 1c levels undergoing emergency PCI / 中国医师杂志

Objective:To investigate the impact of short-term variability in fasting blood glucose (FPG) on the recent major cardiovascular adverse events (MACE) in patients with ST segment elevation myocardial infarction (STEMI) with different levels of glycated hemoglobin (HbA 1c) . Methods:Retrospective analysis was made on the patients with type 2 diabetes mellitus who underwent emergency percutaneous coronary intervention (PCI) due to STEMI from January 2016 to March 2020 in Shenzhen Hospital, Fuwai Hospital, Chinese Academy of Medical Sciences. The patients were divided into HbA 1c compliant group (<6.5%) and non-compliant group (≥6.5%). The blood glucose variability indexes defined included FPG variability score (FPG-VS), variability index independent of FPG mean (VIM) and mean fast plasma glucose (FPG-M). The logistic regression model was used to evaluate the relationship between different HbA 1c levels, blood glucose variability risk indicators, and MACE. Results:A total of 612 patients were ultimately included in the analysis. The blood glucose variability indicators (FPG-VS, VIM) of the HbA 1c non-compliant group (302 cases) were higher than those of the compliant group (310 cases): [FPG-VS: (0.7±0.3) vs (0.4±0.4), P<0.001, VIM: (0.4±0.2) vs (0.3±0.2), P<0.001], while there was no statistically significant difference in FPG-M between the two groups [(7.9±3.2) vs (8.0±3.9), P=0.221]. In the HbA 1c non-compliant group, the correlation between FPG-VS, VIM, and FPG-M and the risk of MACE within 30 days was 0.89(95% CI: 0.69-1.15), 1.21(95% CI: 0.65-2.25), and 1.06(95% CI: 0.97-1.16), respectively (all P>0.05). In the HbA 1c compliant group, FPG-VS was associated with an increase in MACE risk within 30 days ( P=0.04): for each increase in FPG variation ≥1 mmol/L, after multiple factor adjustment, the risk of MACE increased by 8% within 30 days ( OR=1.08, 95% CI: 0.71-1.65); Compared with FPG-VS<20%, FPG-VS≥80% increased the risk of MACE within 30 days by 33% ( OR=1.33, 95% CI: 0.21-8.25, P<0.01), while the correlation between VIM and FPG-M and the risk of MACE within 30 days was 1.65(95% CI: 0.96-2.83) and 1.15(95% CI: 0.98-1.35), respectively (all P>0.05). Conclusions:High FPG-VS is associated with the recent MACE risk in STEMI patients who do not meet HbA 1c standards. After reaching HbA 1c standards, FPG-VS remains an independent MACE risk factor.

The impact of flash glucose monitoring on glycemic control, residual islet function, and patient-reported outcomes in children and adolescents with newly diagnosed type 1 diabetes / 中国医师杂志

Objective:To assess the effect of flash glucose monitoring (FGM) compared with self-monitoring of blood glucose (SMBG) on glycemic control, residual islet function, and patient-reported outcomes in children and adolescents with newly diagnosed type 1 diabetes within 1 year.Methods:133 children and adolescents with newly diagnosed T1DM in the T1D clinic of the Second Xiangya Hospital of Central South University from January 2016 to January 2020 were divided into two groups: FGM group ( n=82) and SMBG group ( n=51). The observation indexes included hemoglobin A1c (HbA 1c), fasting and postprandial blood glucose (FBG and 2 h BG), C-peptide (FCP and 2 h CP) during the one-year follow-up, Δ CP (2 h CP-FCP), patient-reported hypoglycemia and questionnaires regarding self-management of diabetes and quality of life. Results:At 6 months, HbA 1c in 2 groups was significantly decreased (all P<0.05); at 6 to 12 months, HbA 1c in FGM group tended to be stable ( P>0.05); at 12 months, HbA 1c in SMBG group was significantly increased compared with 6 months ( P=0.001). At 12 months, HbA 1c in SMBG group was higher than that in FGM group ( P=0.001). At 12 months, FBG in FGM group was equivalent to the baseline level ( P>0.05), while FBG in SMBG group was significantly higher than the baseline level ( P=0.006). 2 h BG only decreased at the 6th and 12th month in FGM group (all P<0.05). The FCP of SMBG group was significantly decreased at 12 months ( P<0.05), and the 2 h CP, Δ CP in the two groups decreased gradually (all P<0.05). FGM group had more hypoglycemic events at 6 and 12 months (all P<0.05). At 6 months, the score of Self-Management of T1D for Adolescents (SMOD-A) in FGM group was significantly improved ( P=0.001). During the follow-up period, the quality of life score of FGM group was stable ( P>0.05), while the quality of life score of SMBG group had a downward trend ( P=0.052). Conclusions:In newly diagnosed children and adolescents with T1DM, early application of FGM for blood glucose management will help to improve HbA 1c and reduce postprandial blood glucose. In addition, the self-management ability of children with FGM was improved after 6 months.

Objective:To correlate serum 25-hydroxylvitamin D and parathyroid hormone levels with hypertension in patients with type 2 diabetes mellitus.Methods:A total of 100 patients with type 2 diabetes mellitus admitted to Siming Branch, the First Affiliated Hospital of Xiamen University, China from February 2018 to August 2020 were included in this study. These patients were stratified according to hypertension, and serum 25-hydroxyvitamin D level. The correlation between serum 25-hydroxyvitamin D and parathyroid hormone and hypertension was analyzed.Results:Among the 100 patients with type 2 diabetes meliitus, 25 patients had grade 1 hypertension, 30 patients had grade 2 hypertension, 45 patients had grade 3 hypertension, 5 patients (5%) had sufficient levels of 25-hydroxyvitamin D, 10 patients (10%) had insufficient levels of 25-hydroxyvitamin D, 85 patients (85%) had inadequate levels of 25-hydroxyvitamin D. Serum levels of 25-hydroxyvitamin D in patients with grade 1, grade 2, and grade 3 hypertension were (12.18 ± 2.52) μg/L, (12.45 ± 2.39) μg/L, (10.33 ± 1.26) μg/L, respectively, and parathyroid hormone levels were (36.48 ± 0.25) ng/L, (41.15 ± 0.39) ng/L, and (47.52 ± 1.44) ng/L, respectively. As blood pressure increased, the patient's serum levels of 25-hydroxyvitamin D increased first and then decreased, while parathyroid hormone levels gradually increased. However, there were no statistically significant differences in serum levels of 25-hydroxyvitamin D and parathyroid hormone between patients of different hypertension grades ( F = 0.96, 1.93, both P > 0.05). Logistic regression analysis showed that hypertension in type 2 diabetes patients was correlated with age, body mass index, serum 25 hydroxyvitamin D level, glycated hemoglobin and parathyroid hormone level ( OR = 1.076, 1.266, 0.937, 1.257, 1.000, all P < 0.05). Conclusion:The serum levels of 25-hydroxyvitamin D and parathyroid hormone in patients with type 2 diabetes mellitus are related to hypertension.

Establishment of prediction nomogram model of type 2 diabetes mellitus complications based on laboratory indexes such as glycosylated hemoglobin / 中国医师进修杂志

Objective:To study the effect of related laboratory indexes such as glycosylated hemoglobin on the occurrence of complications in patients with type 2 diabetes mellitus, and to construct a nomogram model.Methods:The clinical data of 203 patients with 2 diabetes mellitus from May 2020 to April 2022 in Quzhou Hospital, Zhejiang Medical and Health Group were retrospectively analyzed. Among them, 64 patients had no diabetic complications (control group), and 139 patients had diabetic complications (complication group). The clinical data of the two groups were recorded, and the related influencing factors of complications in patients with type 2 diabetes were analyzed; receiver operating characteristic (ROC) curve was used to analyze the predicting value of significant indexes for the complications in patients with type 2 diabetes; multivariate Logistic regression analysis was used to analyze the independent risk factors of complications in patients with type 2 diabetes; R language software 4.0 "rms" package was used to construct the nomogram model for predicting the complications in patients with type 2 diabetes, the calibration curve was internally validated, and the decision curve was used to evaluate the predictive efficacy of the nomogram model.Results:The hypertension rate, hyperlipemia rate, course of disease, fasting blood glucose, postprandial 2 h blood glucose and glycosylated hemoglobin in complication group were significantly higher in those in control group: 44.60% (62/139) vs. 20.31% (13/64), 48.92% (68/139) vs. 25.00% (16/64), (5.42 ± 0.68) years vs. (4.84 ± 0.51) years, (12.60 ± 2.80) mmol/L vs. (10.20 ± 1.90) mmol/L, (16.50 ± 3.10) mmol/L vs. (12.50 ± 2.90) mmol/L and (9.62 ± 1.33)% vs. (7.96 ± 0.85)%, and there were statistical differences ( P<0.01); there were no statistical differences in gender composition, age, body mass index, smoking rate, drinking rate, albumin and creatinine between the two groups ( P>0.05). ROC curve analysis result showed that the area under the curve of the course of disease, fasting blood glucose, postprandial 2 h blood glucose and glycosylated hemoglobin for predicting the complications in patients with type 2 diabetes were 0.725, 0.752, 0.830 and 0.861, respectively; the optimal cut-off values were 5 year, 11.8 mmol/L, 15.1 mmol/L and 9.23%. Multivariate Logistic regression analysis result showed that hypertension, hyperlipemia, course of disease, fasting blood glucose, postprandial 2 h blood glucose and glycosylated hemoglobin were independent risk factors of complications in patients with type 2 diabetes ( OR = 1.563, 1.692, 1.451, 1.703, 1.506 and 1.805; 95% CI 1.268 to 1.689, 1.483 to 1.824, 1.215 to 1.620, 1.402 to 1.903, 1.303 to 1.801 and 1.697 to 1.926; P<0.05). The hypertension, hyperlipemia, course of disease, fasting blood glucose, postprandial 2 h blood glucose and glycosylated hemoglobin were used as predictors to construct a nomogram model for predicting the complications in patients with type 2 diabetes. Internal validation result showed that the nomogram model predicted the complications with good concordance in patients with type 2 diabetes (C-index = 0.815, 95% CI 0.796 to 0.843); the nomogram model predicted the complications in patients with type 2 diabetes at a threshold >0.18, provided a net clinical benefit, and all had higher clinical net benefits than hypertension, hyperlipemia, course of disease, fasting blood glucose, postprandial 2 h blood glucose and glycosylated hemoglobin. Conclusions:The nomogram model constructed based on hypertension, hyperlipemia, course of disease, fasting blood glucose, postprandial 2 h blood glucose and glycosylated hemoglobin has better clinical value in predicting the complications in patients with type 2 diabetes.

Objetivo: Describir las características clínicas y epidemiológicas de pacientes con alfatalasemia atendidos en un hospital nacional pediátrico. Métodos: Estudio observacional descriptivo de corte transversal. Se estudia a 60 pacientes del Servicio de Hematología del Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", Caja Costarricense de Seguro Social, del 1° de enero de 2018 al 31 de enero de 2019, cuyas edades están comprendidas entre los 0 meses y 12 años 11 meses de edad, con índices hematimétricos sugestivos de alfa-talasemia y con electroforesis de hemoglobina patrón AA con HbA2 normal o disminuida. Análisis molecular: identificación de 21 mutaciones y deleciones más frecuentes para el gen de alfa-globina: 3.7, 4.2, 20.5, MED, FIL, SEA, THAI, anti-3.7 triplicación, HbConstant Spring, HbQuonSze, Hb Adana, HbKoya Dora, HbIcara, HbPakse, a2 poli A-1/2, a2-cd142, a1-cd14, a2-init-cd, a2-cd19, a2-IVS1, a2-cd59. Se utiliza el método de amplificación por reacción en cadena de la polimerasa e hibridación inversa del ácido desoxirribonucleico genómico en leucocitos de sangre periférica de los pacientes. Resultados: Se confirma la enfermedad en 44/60 casos (73%). La edad media al diagnóstico para estos casos es de 4.9 años (desviación estándar 3.0), predominó el sexo femenino en 52.3% de los casos. La provincia de Guanacaste reportó la mayor prevalencia de la enfermedad. El defecto genético delecional -3.7 Kb es el genotipo más frecuente. El fenotipo en el 77.2% de los casos indicó portador silente de alfa-talasemia. El 84.1% de los sujetos positivos para alfa-talasemia correlacionó con hipocromía, microcitosis y eritrocitosis en el hemograma inicial. El 9% de los casos evidenció la coexistencia de alfa-talasemia y anemia por deficiencia de hierro. Conclusiones: Este estudio demuestra que los hallazgos de índices eritrocitarios que indiquen hipocromía y microcitosis con aumento del cómputo de eritrocitos, índices férricos normales y una electroforesis de hemoglobina con patrón normal (AA) sugieren ser estudiados molecularmente por alfa-talasemia. La electroforesis de hemoglobina reportada como normal no excluye la condición de alfa-talasemia y debe realizarse el estudio molecular.

Objective: Describe the clinical and epidemiological characteristics of patients with alpha thalassemia in the Hematology Service of a national pediatric hospital. Methods: Cross-sectional descriptive observational study. 60 patients from the Hematology Service of the National Children's Hospital "Dr. Carlos Sáenz Herrera", Costa Rican Social Security Fund, from January 1, 2018 to January 31, 2019, with hematometric indices suggestive of alphaThalassemia, with AA standard hemoglobin electrophoresis with normal or decreased HbA2 with ages between 0 months and 12 years 11 months old. Molecular analysis: Identification of 21 mutations and deletions that includes the detection of the most frequent deletions/mutations for the alpha globin gene: 3.7, 4.2, 20.5, MED, FIL, SEA, THAI, anti-3.7 tripling, HbConstant Spring, HbQuonSze, Hb Adana, HbKoya Dora, HbIcara, HbPakse, a2 poli A-1/2, a2-cd142, a1-cd14, a2-init-cd, a2-cd19, a2-IVS1, a2-cd59. The reverse hybridization PCR amplification method of genomic DNA in peripheral blood leukocytes of patients isused. Results: Of the 60 cases studied, in 44/60 (73%) cases the disease is confirmed. The average age at diagnosis for these cases is 4.9 years (SD 3.0), the female sex predominated in 52.3% of the cases. Guanacaste reported the highest prevalence of the disease. The deletional genetic defect -3.7 Kb was the most frequent genotype and the phenotype in 77.2% of the cases was he silent carrier of alpha thalassemia. In 84.1% of subjects positive for alpha thalassemia, it correlated with hypochromia, microcytosis, and erythrocytosis in the initial blood count. 9% of the cases showed the coexistence of alpha thalassemia and iron deficiency anemia. Conclusions: This study demonstrates that the findings of erythrocyte indices that indicate hypochromia and microcytosis with increased erythrocyte count; normal iron indices and a normal hemoglobin (AA) electrophoresis pattern suggest that they should be studied molecularly for alpha thalassemia. Hemoglobin electrophoresis reported as normal does not exclude the condition of alpha thalassemia and the molecular study must be carried out.

Association between glycemic control and albuminuria among Peruvian adults with diabetes mellitus 2: a cross-sectional analytical study

ABSTRACT BACKGROUND: Albuminuria is a risk factor for microvascular and macrovascular complications in the diabetic population. However, few studies have correlated poor glycemic control and albuminuria prevalence in Hispanic populations. OBJECTIVE: To evaluate the association between glycemic control and albuminuria among Peruvian adults with type 2 diabetes mellitus (T2DM). DESIGN AND SETTING: Cross-sectional analytical study among adults with T2DM in Lima, Peru. METHODS: We included adults over 18 years old who were in a clinical follow-up program at a private clinic in Lima in 2018. Poor glycemic control was defined as a serum value of glycosylated hemoglobin A1C (HbA1C) ≥ 7%. Albuminuria was defined as albumin values > 30 mg/dl in the first morning urine. We generated generalized linear regression models from the Poisson family with robust variance. We calculated the crude and adjusted prevalence ratios (PRs) with their 95% confidence interval (CI). RESULTS: We analyzed 907 participants of median age 58 years (interquartile range, IQR 49 to 66), and 62.8% were males. The prevalence of poor glycemic control was 39.8%, and the prevalence of albuminuria was 22.7%. The prevalences of albuminuria in groups with poor glycemic control and adequate glycemic control were 32.7% and 16.1%, respectively. In the adjusted regression analysis, we found a statistically significant association between poor glycemic control and albuminuria (annual percentage rate, aPR = 1.70; 95% CI: 1.28-2.27). CONCLUSIONS: The prevalence of poor glycemic control and albuminuria was high in our study population. Moreover, Peruvian T2DM adults with poor glycemic control were more likely to have albuminuria.

Depression scores correlate with glycosylated hemoglobin a levels in type 2 diabetics from a mayan community / Los puntajes de depresión se correlacionan con los niveles de hemoglobina glucosilada en diabéticos tipo 2 de una comunidad maya

Abstract Objective: To assess whether depression and quality of life scores correlate with glycosylated hemoglobin A (HbA1c) levels in type 2 diabetes mellitus (T2DM) patients of predominant Mayan ethnicity, from a rural community in the state of Yucatán, Mexico. Materials and methods: Instruments: for depression, CES-D (cutoff ≥ 16); for quality of life, D-39; criterion for poor glycemic control, HbA1c ≥ 8%. Results: Depression was detected in 36.3% of 33 diabetic subjects (10 men, 23 women), and their HbA1c levels (mean ± SD) were higher (10.7 ± 2.5%) than for those without depression (8.6 ± 2.2%, p = 0.015; unpaired Student's t-test, two-tailed). Depression occurred in 33.3% of diabetics with HbA1c ≥8%, but only in 3.0% of those with HbA1c < 8% (p = 0.027, Fisher's exact test). HbA1c levels positively correlated with CES-D scores (r2 =0.135; p = 0.035; Pearson). D-39 "Anxiety-Worry" (AW) dimension scores were higher in diabetics with depression (43.3 ± 22.2) than in those without depression (17.7 ± 17.8; p = 0.005, Mann-Whitney U-test). A positive correlation was found between CES-D and AW scores (r2 = 0.304; p = 0.001; Pearson). Conclusions: Considering that depression and anxiety have been related to poor self-care for achieving a good glycemic control, we propose the concomitant use of CES-D and D-39, which are validated and easy-to-apply instruments, as screening tests to detect depression and anxiety in T2DM patients residing in rural communities. Therefore, if patients test positive on one or both instruments, they can be referred to a psychiatrist to confirm the diagnosis and provide appropriate therapy. This would help to promote adherence to diabetes control measures and improve their quality of life.

Resumen Objetivo: Evaluar si las puntuaciones de depresión y calidad de vida se correlacionan con los niveles de hemoglobina glucosilada (HbA1c) en pacientes con diabetes mellitus tipo 2 (DM2) de etnia maya predominante, de una comunidad rural en el estado de Yucatán, México. Materiales y Métodos: Instrumentos: para depresión, CES-D (punto de corte ≥ 16); para calidad de vida, D-39; criterio de mal control glucémico, HbA1c ≥ 8%. Resultados: Se detectó depresión en el 36.3% de 33 sujetos diabéticos (10 hombres, 23 mujeres), y sus niveles de HbA1c (media ± DE) fueron más altos (10.7 ± 2.5%) que para los que no tenían depresión (8.6 ± 2.2%, p = 0.015; prueba t de Student, no pareada). La depresión se presentó en el 33.3% de los diabéticos con HbA1c ≥ 8%, pero solo en el 3.0% de aquellos con HbA1c <8% (p = 0.027, prueba exacta de Fisher). Los niveles de HbA1c se correlacionaron positivamente con las puntuaciones CES-D (r2 = 0.135; p = 0.035; Pearson). Los puntajes de la dimensión "Ansiedad-Preocupación" (AW) del D-39 fueron más altos en diabéticos con depresión (43.3 ± 22.2) que en aquellos sin depresión (17.7 ± 17.8; p = 0.005, prueba U de Mann-Whitney). Se encontró una correlación positiva entre las puntuaciones CES-D y AW (r2 = 0.304; p = 0.001; Pearson). Conclusiones: Considerando que la depresión y la ansiedad han sido asociadas a autocuidados inadecuados para alcanzar un buen control glicémico, proponemos el uso concomitante de CES-D y D-39, que son instrumentos validados y de fácil aplicación, como pruebas de cribado para detectar depresión y ansiedad en pacientes con DM2 residentes en comunidades rurales. Por lo tanto, si los pacientes dan positivo en uno o ambos instrumentos, se les puede derivar a un psiquiatra para confirmar el diagnóstico y proporcionar la terapia adecuada. Esto ayudaría a promover el cumplimiento de las medidas de control de la diabetes y a mejorar su calidad de vida.

Glycated Haemoglobin Levels and Its Effect on Outcomes in Cardiac Surgery

Abstract There remains a significant paucity of information evaluating the effect of glycated HbA1c levels and its theorized effect on mortality and morbidity rates following cardiac surgery. Diabetes is a very common comorbidity in patients undergoing open heart surgery, as there is a shift in patient characteristics and greater risk. Currently, there is no clear consensus that an increase in HbA1c level is associated with increased perioperative mortality rate. However, the reported literature is more commonly able to demonstrate that elevated HbA1c levels is associated with increased rates of wound infection, cardiovascular events and renal failure, and thus, higher post-operative morbidities. This review aims to examine and synthesis the evidence behind each of the morbidities and mortalities associated with open heart surgery and the impact of high HbA1c on the reported outcomes.

The importance of optimal 25-hydroxyvitamin D levels in the glycemic control of older adults with type 2 Diabetes Mellitus: Data from the study on aging and longevity EELO

INTRODUCTION: Optimal serum levels of vitamin D are of great importance, especially in populations with comorbidities such as Diabetes Mellitus (DM). OBJECTIVE: The study evaluated the relationship between hypovitaminosis D and glycemic control in older adults with type 2 DM. METHODS: Cross-sectional and prospective study, part of the EELO project (Study on Aging and Longevity), conducted in Southern Brazil. Glycated hemoglobin (diabetes ≥6.5%) and serum levels of vitamin D (25(OH)D) were evaluated. Hypovitaminosis D was determined using cutoff points <20 and <30 ng/mL). Multivariate logistic regression was used to assess the risk of having uncontrolled DM. RESULTS: Of the 120 older adults included in the study, aged between 60 and 87 years, 74.2% were women, 66.7% used hypoglycemic medications and 75.8% exhibited uncontrolled diabetes. An inverse correlation was observed between the levels of 25(OH) D and glycated hemoglobin (rS=-0.19, p=0.037), suggesting that low levels of vitamin D are associated with poor glycemic control in diabetic individuals. The prevalence of hypovitaminosis D when using the cutoff points of <20 and <30 ng/mL were 34.2% and 75.0%, respectively. The odds ratio (OR) analysis showed that individuals with 25(OH)D<20ng/mL have almost 4 times more risk of having uncontrolled DM (OR:3.94; CI95%:1.25-12.46, p=0.02) when compared to the older adults with sufficient levels of vitamin D. CONCLUSION: The results indicate that the optimal serum levels currently recommended for 25(OH)D should preferably be 30 ng/mL or higher to contribute to better glycemic control in older adults with type 2 DM.

INTRODUÇÃO: Os níveis séricos ideais de vitamina D são de grande importância, especialmente na população com comorbidades como o Diabetes Mellitus (DM). OBJETIVO: O estudo avaliou a relação entre hipovitaminose D e controle glicêmico em idosos com DM tipo 2. MÉTODOS: Estudo transversal e prospectivo, parte do projeto EELO (Estudo sobre Envelhecimento e Longevidade), no Sul do Brasil. A hemoglobina glicada (diabetes ≥6,5%) e os níveis séricos de vitamina D (25(OH)D) foram avaliados. Hipovitaminose D foi determinada usando ponto de corte <20 e <30 ng/mL. Regressão logística multivariada foi utilizada para avaliar o risco de ter DM descompensado. RESULTADOS: Dos 120 idosos incluídos no estudo, idade entre 60 a 87 anos, 74,2% eram mulheres, 66,7% faziam uso de medicamentos hipoglicemiantes e 75,8% apresentavam diabetes descompensada. Uma correlação inversa foi observada entre os níveis de 25(OH)D e hemoglobina glicada (rS=-0,19; p=0.037), sugerindo que baixos níveis de vitamina D está associado a um pior controle glicêmico em diabéticos. A prevalência de hipovitaminose D quando se utiliza ponto de corte <20 e <30 ng/mL foi de 34,2% e 75,0%, respectivamente. A análise Odds ratio (OR) mostrou que indivíduos com 25(OH)D<20 ng/mL tem quase 4 vezes mais risco de ter DM descompensado (OR:3,94; IC95%:1,25­12,46; p=0,02) quando comparado aos idosos com níveis suficientes de vitamina D. CONCLUSÃO: Os resultados indicam que os níveis sérios ideais atualmente recomendados para 25(OH)D maior ou igual a 30 ng/ml contribuem para o melhor controle glicêmico na população idosa com DM tipo 2.

ABSTRACT Objective : to estimate reference intervals (RIs) of creatinine and glycated hemoglobin (HbA1c) in the Brazilian adult population. Methods : a cross-sectional study, using the National Health Survey (Pesquisa Nacional de Saúde, PNS) database, between 2014-2015, consisting of 8,952 adults. To establish RIs, exclusion criteria were applied, outliers were removed and stratification was performed. After these procedures, the sample consisted of 2,723 adults for HbA1c and 2,738 adults for creatinine. Differences were evaluated by means of the Mann Whitney and Kruskal Wallis tests (p≤0.05). Results : men (RI: 0.69-1.25; median: 0.95 mg/dL) had higher RIs for creatinine than women (RI: 0.53-1.05; median: 0.74 mg/dL) and higher lower limit (LL) values and median HbA1c (male: RI: 4.55-5.97; median: 5.3%; female: RI: 4.49-5.97; median: 5.20%) (p≤0.05). In women, the RIs for creatinine were higher in the age groups between 45 and 59 years old (RI: 0.55-1.04; median: 0.77 mg/dL) and from 60 years old (RI: 0.54-0.98; median: 0.77 mg/dL (p≤0.05). For HbA1c, men had higher RIs from age 60 (RI: 4.65-6.07; median: 5.44%) and women from 45 years old (45-59: RI: 4.61-6.05; median: 5.40%; and 60 years old or more: RI: 4.82-6.03; median: 5.50%) (p≤0.05). For creatinine, lower RI LLs and more prominent medians were observed in white-skinned adults (RI: 0.56-1.19; median: 0.85%) when compared to brown-skinned (RI: 0.55-1.19; median: 0.84%) (p≤0.05). Conclusion : appropriate RIs make it possible to unveil the health conditions of Brazilian adults and can support proper identification of chronic kidney disease and diabetes.
