RESUMEN
Introdução: Diabetes mellitus (DM) é uma doença crônica, não transmissível, cuja prevalência tem aumentado mundialmente. Seu manejo adequado na Atenção Primária à Saúde (APS) pode reduzir suas complicações e as internações por condições sensíveis à atenção primária. Objetivo: Comparar indicadores de qualidade da atenção a pessoas com diabetes atendidas na rede básica de saúde do Brasil e suas diferenças por região. Métodos: Com delineamento transversal, utilizaram-se dados dos Ciclos I e III do Programa de Melhoria do Acesso e da Qualidade (PMAQ). Os desfechos foram indicadores sintéticos, operacionalizados a partir de 24 variáveis: i) acesso; ii) disponibilidade de insumos e equipamentos em condições de uso; iii) disponibilidade de medicamentos em quantidade suficiente; iv) organização e gestão; v) cuidado clínico; e vi) relato de cuidado adequado. Foram calculadas as diferenças em pontos percentuais (p.p.) dos indicadores entre 2012 e 2018, e os dados foram estratificados por região. Resultados: No geral, houve uma melhora no cuidado à pessoa com DM na APS do Brasil e regiões entre as equipes participantes do PMAQ, entre 2012 e 2018. As prevalências de acesso, disponibilidade de insumos/equipamentos, medicamentos, oferta, organização e gestão apresentaram aumento de, no mínimo, 10 p.p. no período de 6 anos, mas podem melhorar. Conclusões: Considerando que a ocorrência de DM está aumentando no país, faz-se necessário maior investimento na estrutura dos serviços e em programas de educação permanente dos profissionais de saúde.
Introduction: Diabetes Mellitus (DM) is a non-communicable chronic disease whose prevalence has been increasing worldwide. Its adequate management in Primary Health Care (PHC) can reduce complications and hospitalizations for conditions sensitive to primary care. Objective: To compare quality indicators for the care of people with diabetes treated in the basic health network in Brazil and their differences by region. Methods: With a cross-sectional design, data from Cycles I and III of the PMAQ were used. The outcomes were synthetic indicators, operationalized from 24 variables: i) access; ii) availability of supplies and equipment in usable conditions; iii) availability of medications in sufficient quantities; iv) organization and management; v) clinical care; and vi ) report of adequate care. Differences in percentage points (p.p.) of the indicators between 2012 and 2018 were calculated, and the data were stratified by region. Results: Overall, there was an improvement in the care of people with DM in PHC in Brazil and regions among the teams participating in PMAQ, between 2012 and 2018. The prevalence of access, availability of supplies/equipment, medications, demand, organization, and management showed an increase of at least 10 p.p. within six years, but they can improve. Conclusions: Considering that the occurrence of DM is increasing in the country, greater investment is necessary in the structure of services and in continuing education programs for health professionals.

Resumen Introducción: la organización mundial de la salud estima que 2000 millones de personas padecen anemia, mientras que la pre-diabetes y la diabetes afectan aproximadamente a 352 y 460 millones de personas, respectivamente. La anemia es una complicación frecuente en la diabetes mellitus (DM). Objetivo: evaluar la asociación y probabilidad de alteraciones de la hemoglobina en pre-diabéticos y diabéticos. Metodología: estudio descriptivo, retorspectivo y transversal, la población fue de 1103 pacientes (211 prediabéticos, 223 diabéticos y 669 normoglucémicos), la muestra fue el total de la población que cumplió con los criterios de inclusión y exclusión: adultos normoglucémicos y pre-diabéticos sin presencia de enfermedad aguda o crónica al momento del examen. La asociación entre variables se realizó por medio de la prueba de chi-cuadrado y la probabilidad fue determinada por la prueba de Odds Ratio. Resultados: las mujeres pre-diabéticas tuvieron una probabilidad 1.72 mayor de anemia que mujeres no diabéticas. Los hombres pre-diabéticos tuvieron una probabilidad 2.80 veces mayor de anemia que los no diabéticos. Las mujeres diabéticas tuvieron una probabilidad 2,37 más alta de tener anemia, mientras que los hombres diabéticos tuvieron una probabilidad 4,41 veces más alta que lo hombres no diabéticos de padecer anemia. Conclusiones: pacientes pre-diabéticos tienen mayor probabilidad de anemia que en no diabéticos. Es posible que la hiperglucemia persistente en pre-diabéticos se asocie a cambios en la concentración de esta hemoproteína años antes del desarrollo de diabetes por mecanismos similares, pero de forma incipiente.
Abstract Introduction: The World Health Organization estimates that 2 billion people suffer from anemia, while pre-diabetes and diabetes affect approximately 352 and 460 million people, respectively. Anemia is a frequent complication in diabetes mellitus. Objective: To evaluate the association and probability of hemoglobin alterations in pre-diabetics and diabetics. Methodology: Descriptive, retrospective and cross-sectional study, the population was 1103 patients (211 prediabetics, 223 diabetics and 669 normoglycemics), the sample was the total population that met the inclusion and exclusion criteria: normoglycemic and prediabetic adults without presence of acute or chronic disease at the time of examination. The association between variables was performed using the chi-square test and the probability was determined by the Odds Ratio test. Results: Pre-diabetic women had a 1.72 higher probability of anemia than non-diabetic women. Pre-diabetic men were 2.80 times more likely to have anemia than non-diabetics. Diabetic women were 2.37 times more likely to have anemia, while diabetic men were 4.41 times more likely than non-diabetic men to have anemia. Conclusions: Pre-diabetic patients are more likely to have anemia than non-diabetics. It is possible that persistent hyperglycemia in pre-diabetics is associated with changes in the concentration of this hemoprotein years before the development of diabetes by similar mechanisms, but in an incipient manner.
RESUMEN
SUMMARY OBJECTIVE: The objective of this study was to investigate serum Metrnl levels in pregnant women with gestational diabetes mellitus and compare them with pregnant women without gestational diabetes mellitus. METHODS: The gestational diabetes mellitus group consisted of 87 pregnant women diagnosed with gestational diabetes mellitus, and the control group consisted of 93 healthy pregnant women without gestational diabetes mellitus. Serum Metrnl levels were determined by the enzyme-linked immunosorbent assay method. RESULTS: The two groups were similar in terms of demographic features. The median serum Metrnl level was found to be 1.16 ng/mL in the gestational diabetes mellitus group, while it was determined as 2.2 ng/mL in the control group (p=0.001). The two groups were divided into two subgroups based on participants' body mass index, normal weight and overweight. The lowest median Metrnl level was detected in the normal weight gestational diabetes mellitus group, followed by the overweight gestational diabetes mellitus group, normal weight control group, and overweight control group (1.1, 1.2, 2, and 2.4 ng/mL, respectively). Receiver operating curve analysis was performed to determine the value of the serum Metrnl level in terms of predicting gestational diabetes mellitus. The area under the curve analysis of serum Metrnl for gestational diabetes mellitus estimation was 0.768 (p=0.000, 95%CI 0.698-0.839). The optimal cutoff value for serum Metrnl level was determined as 1.53 ng/mL with 69% sensitivity and 70% specificity. CONCLUSION: Serum Metrnl levels in pregnant women with gestational diabetes mellitus were found to be significantly lower than in pregnant women without gestational diabetes mellitus. The mechanisms underlying the decrease in serum Metrnl levels in gestational diabetes mellitus remain unclear for now, and future studies will reveal the role of Metrnl in the pathophysiology of gestational diabetes mellitus.
RESUMEN
OBJECTIVE: To compare the perinatal outcomes of women with Gestational Diabetes Mellitus (GDM), between pregnant treated only with lifestyle changes and pregnant treated with insulin and lifestyle changes. METHODS: Prospective cohort study with follow-up of 64 women with GDM during the prenatal care and postpartum period until hospital discharge, divided into a control group (43) and an insulin group (21), with collection of sociodemographic, clinical, glycemic control and perinatal outcome data. Fetal macrosomia (≥ 4 Kg), or large-for-gestational-age newborns were considered the primary outcome of the research. RESULTS: Pre-pregnancy BMI (31.2 ± 3.9 versus 28.8 ± 5.5), diastolic blood pressure (75 ± 8.7 versus 69 ± 6.9) and postprandial blood glucose (136.6 versus 115.4) ââwere higher in the insulin group, respectively. The control group had an average birth weight of 3058 g and an incidence of preterm birth of 11.6 %, while the insulin group had an average birth weight of 3203 g, with an incidence of preterm birth of 4.8 %. The majority of newborns had an adequate weight for their gestational age. Even all participants met glycemic goals, in the insulin group the Apgar score at the 5th minute and exclusive breastfeeding was lower, had 100 % of resuscitation cases, and a longer inpatient period. CONCLUSION: These data reinforce that even during prenatal care with lifestyle changes, newborns of women with GDM treated with insulin had worse outcomes, including clinical complications and less exclusive breastfeeding. It is important in prenatal care to identify neonates with risk for prevention and health promotion measures.
RESUMEN
Several studies have demonstrated that diabetes mellitus can increase the risk of cardiovascular disease and remains the principal cause of death in these patients. Costameres connect the sarcolemma with the cytoskeleton and extracellular matrix, facilitating the transmission of mechanical forces and cell signaling. They are related to cardiac physiology because individual cardiac cells are connected by intercalated discs that synchronize muscle contraction. Diabetes impacts the nanomechanical properties of cardiomyocytes, resulting in increased cellular and left ventricular stiffness, as evidenced in clinical studies of these patients. The question of whether costameric proteins are affected by diabetes in the heart has not been studied. This work analyzes whether type 1 diabetes mellitus (T1DM) modifies the costameric proteins and coincidentally changes the cellular mechanics in the same cardiomyocytes. The samples were analyzed by immunotechniques using laser confocal microscopy. Significant statistical differences were found in the spatial arrangement of the costameric proteins. However, these differences are not due to their expression. Atomic force microscopy was used to compare intrinsic cellular stiffness between diabetic and normal cardiomyocytes and obtain the first elasticity map sections of diabetic living cardiomyocytes. Data obtained demonstrated that diabetic cardiomyocytes had higher stiffness than control. The present work shows experimental evidence that intracellular changes related to cell-cell and cell-extracellular matrix communication occur, which could be related to cardiac pathogenic mechanisms. These changes could contribute to alterations in the mechanical and electrical properties of cardiomyocytes and, consequently, to diabetic cardiomyopathy.NEW & NOTEWORTHY The structural organization of cardiomyocyte proteins is critical for their efficient functioning as a contractile unit in the heart. This work shows that diabetes mellitus induces significant changes in the spatial organization of costamere proteins, t tubules, and intercalated discs. We obtained the first elasticity map sections of living diabetic cardiomyocytes. The results show statistical differences in the map sections of diabetic and control cardiomyocytes, with diabetic cardiomyocytes being stiffer than normal ones.

The PPARG gene encodes a member of a nuclear receptor superfamily known as peroxisome proliferator-activated gamma (PPARγ). PPARγ plays an essential role in adipogenesis, stimulating the differentiation of preadipocytes into adipocytes. Loss-of-function pathogenic variants in PPARG reduce the activity of the PPARγ receptor and can lead to severe metabolic consequences associated with familial partial lipodystrophy type 3 (FPLD3). This review focuses on recent scientific data related to FPLD3, including the role of PPARγ in adipose tissue metabolism and the phenotypic and clinical consequences of loss-of-function variants in the PPARG gene. The clinical features of 41 PPARG pathogenic variants associated with FPLD3 patients were reviewed, highlighting the genetic and clinical heterogeneity observed among 91 patients. Most of them were female, and the average age at the onset and diagnosis of lipoatrophy was 21 years and 33 years, respectively. Considering the metabolic profile, hypertriglyceridemia (91.9% of cases), diabetes (77%), hypertension (59.5%), polycystic ovary syndrome (58.2% of women), and metabolic-dysfunction-associated fatty liver disease (87,5%). We also discuss the current treatment for FPLD3. This review provides new data concerning the genetic and clinical heterogeneity in FPLD3 and highlights the importance of further understanding the genetics of this rare disease.

BACKGROUND: Diabetes affects 4.5% of people living with HIV in Mexico. This study aims to describe the diabetes cascade of care (DMC) in people with HIV in a tertiary center in Mexico City. METHODS: We conducted a single-center review of people with HIV aged over 18, using medical records of active people enrolled at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (INCMNSZ) HIV Clinic (HIVC). Our analysis focused on their last visit to describe the DMC, aiming to identify gaps in control goals. We included people who had a consultation within the 12 months preceding May 2020. RESULTS: Out of the 2072 active people, medical records were available for 2050 (98.9%). Among these, 326 people (15.9%) had fasting glucose (FG) abnormalities, of which 133 (40.7%) had diabetes. The prevalence of diabetes among people with HIV was of 6.4% (133/2050). Regarding the DMC, the following proportions of people achieved control goals: 133/133 (100%) received medical care in the last 12 months, 123/123 (100%) had blood pressure (BP) <140/90 mmHg, 73/132 (55.3%) had LDL cholesterol (c-LDL) <100 mg/dl, 63/132 (47.7%) had FG <130 mg/dl, 50/116 (43.1%) had glycosylated hemoglobin (HbA1c) <7%. ABC goals (HbA1c <7%, c-LDL <100 mg/dl, BP <140/90 mmHg) were met in 28/109 (25.6%) people. 126/133 (94%) people with HIV achieved HIV-viral load <50 copies/mL. CONCLUSIONS: Despite the high rate of viral suppression among people with HIV and diabetes, significant challenges remain in achieving comprehensive diabetes control. These findings highlight the need for targeted interventions to improve metabolic outcomes and the overall management of diabetes in people with HIV.

Diabetes mellitus is associated with changes in intestinal morphology and the enteric nervous system. We previously reported constipation in Goto-Kakizaki (GK) rats, a non-obese model for type 2 diabetes mellitus. AIM: The morpho-quantitative analysis of myenteric plexus neurons in the small and large intestines of 120-day-old male GK rats was investigated. METHODS: The diabetes was confirmed by high fasting blood glucose levels. The myenteric plexus was evaluated through wholemount immunofluorescence. The morpho-quantitative analyses included evaluating neuronal density (neurons per ganglion) of the total neuronal population, the cholinergic and nitrergic subpopulations, and enteric glial cells per ganglion. The cell body area of 100 neurons per segment per animal was measured. RESULTS: The total neurons and nitrergic subpopulation were unaltered in the GK rats' small and large intestines. The cholinergic subpopulation exhibited decreased density in the three segments of the small intestine and an increased number in the proximal colon of the GK rats. The number of enteric glial cells increased in the ileum of the GK rats, which could indicate enteric gliosis caused by the intestinal inflammatory state. The area of the cell body was increased in the total neuronal population of the jejunum and ileum of the GK rats. Frequency histograms of the cell body area distribution revealed the contribution of cholinergic neurons to larger areas in the jejunum and nitrergic neurons in the ileum. CONCLUSION: The constipation previously reported in GK rats might be explained by the decrease in the density of cholinergic neurons in the small intestine of this animal model.

Background/Objectives: Periodontitis (P), a chronic inflammatory condition that affects the supportive tissues around the teeth, is three to four times more prevalent in individuals with diabetes mellitus (DM), with a direct correlation between its severity and the levels of glycosylated hemoglobin (HbA1c). This study aimed to evaluate the periodontal clinical parameters following non-surgical periodontal treatment (NSPT) in P patients with or without type 2 DM. Methods: Forty patients with P were divided into two groups: Group DM/P and Group P. All the patients were assessed at baseline and at 90 and 180 days after receiving NSPT. The parameters evaluated included the HbA1c level, plaque index (PI), probing pocket depth (PPD), clinical attachment level (CAL), and bleeding on probing (BoP). A statistical analysis was performed with a significance level set at α = 5%. Results: There were significant differences in the HbA1c levels between the DM/P and P groups at baseline, 90, and 180 days, as expected. Importantly, the HbA1c levels did not change after NSPT. Group P showed a significant reduction in both the PI and the BoP values at 90 and 180 days (p < 0.05). In contrast, Group DM/P demonstrated a significant increase in the percentage of sites with a PPD ≥ 5 mm at 180 days (p < 0.05). Additionally, Group P exhibited an increase in sites with a PPD ≤ 4 mm and a decrease in sites with a PPD ≥ 5 mm at both 90 and 180 days (p < 0.05). Conclusions: Our findings suggest that DM may compromise the effectiveness of NSPT, potentially hindering favorable outcomes during the follow-up period.
RESUMEN
BACKGROUND: Gestational diabetes mellitus (GDM) is the main cause of hyperglycemia in pregnancy and is related to complications throughout the gestational and post-partum period. OBJECTIVES: To analyze the pregnancy outcomes related to the occurrence of GDM in women and their offspring. METHODS: Third-trimester pregnant women were interviewed and monitored until childbirth. The diagnosis of GDM, blood glucose ≥ 92 mg/dL, was defined by the criteria of the International Association of the Diabetes and Pregnancy Study Groups (IADPSG). RESULTS: A total of 138 women participated, and there were 136 births (due to 2 fetal losses); 23 (16.7%) were diagnosed with GDM. The risk of complications during childbirth was higher among pregnant women with GDM (RR 3.40; 95%CI 1.65-7.00), as was the occurrence of cesarean birth (RR 1.9; 95%CI 1.46-2.59). The occurrence of preterm birth did not show a significant difference between GDM/non-GDM groups. There was a non-significant association in adjusted analyses of macrosomia (birth weight ≥ 4000 g) among newborns born to mothers with GDM (RR 1.27; 95%CI 0.67-2.38). For newborns born to pregnant women with GDM, there was a higher risk for the following outcomes: large for gestational age (LGA) (3.29 95%CI 1.62-6.64), low Apgar (4.98 95%CI 2.32-10.69), and birth asphyxia (9.51 95%CI 3.42-26.48). CONCLUSIONS: The findings reinforce that GDM is an important risk factor for adverse pregnancy outcomes for women and their offspring.
RESUMEN
BACKGROUND: Digital educational technologies in health have been an important instrument for promoting learning, self-care, self-esteem, and security regarding prevention and health promotion actions that lead to changes in behavior, mainly for non-communicable disease patients, such as type 2 Diabetes Mellitus (DM 2). OBJECTIVE: This study aimed to describe a protocol for evaluating the effect of an app for cell phones and tablets on the blood glucose of older adults with DM 2. METHODS: The protocol will be used to compare the effectiveness of an application for mobile devices concerning the educational booklet in reducing Glycated Hemoglobin in older adults with DM 2 in Primary Health Care. This protocol is part of a Randomized Clinical Trial project entitled Effectiveness of a Mobile Device Application on Glycated Hemoglobin in Elderly People with Type 2 Diabetes Mellitus: a Randomized Clinical Trial. RESULTS: The protocol was structured in the following phases: (i) sample calculation, (ii) invitation to participate in the study according to the eligibility criteria; (iii) participant registration; (iv) randomization and allocation of participants into groups (double blinding); (v) application of the intervention; (vi) post-intervention procedures (post-test); (vii) data analysis. CONCLUSION: It is expected that encouraging studies on the impact of a mobile application will improve and enhance health education focused on self-care for older adults with DM 2, potentially influencing the local health system by reducing hospitalizations due to conditions that are sensitive to primary care, since health promotion and prevention of DM-related illnesses will be the main focus of the application and booklet developed.

Growth factor receptor-bound protein 2 (GRB2) is a negative regulator of insulin signaling and a positive regulator of angiogenesis. Its expression is increased in a mouse model of retinal neovascularization and in patients with type 2 diabetes mellitus (T2DM). This case-control study aimed to investigate the association between the rs9896052 polymorphism (A>C) upstream of GRB2 and proliferative diabetic retinopathy (PDR) in patients with T2DM from Southern Brazil, taking into consideration self-reported skin color (white or non-white) and the known duration of diabetes (<10 years or ≥10 years). Genotypes were determined by real-time PCR in 838 patients with T2DM (284 cases with PDR and 554 controls without DR). In the total study group and in the analysis stratified by skin color, the genotype and allele frequencies were similar between cases and controls. However, among patients with less than 10 years of diabetes, the C allele was more frequent in cases than in controls (63.3% versus 51.8%, p = 0.032), and the CC genotype was independently associated with an increased risk of PDR (adjusted OR = 2.82, 95% CI 1.17-6.75). In conclusion, our findings support the hypothesis that the rs9896052 polymorphism near GRB2 is associated with PDR in Brazilian patients with T2DM.

Obesity causes insulin resistance (IR) through systemic low-grade inflammation and can lead to type 2 diabetes mellitus (T2DM). However, the mechanisms that cause IR and T2DM in non-obese individuals are unclear. The Goto-Kakizaki (GK) rat develops IR spontaneously and is a model of non-obese T2DM. These rats exhibit hyperglycemia beginning at weaning and exhibit lower body mass than control Wistar rats. Herein, we tested the hypothesis that macrophages of GK rats are permanently in a pro-inflammatory state, which may be associated with a systemic inflammation condition that mimics the pathogenesis of obesity-induced T2DM. Using eighteen-week-old GK and control Wistar rats, we investigated the proportions of M1 (pro-inflammatory) and M2 (anti-inflammatory) macrophages isolated from the peritoneal cavity. Additionally, the production of inflammatory cytokines and reactive oxygen species (ROS) in cultured macrophages under basal and stimulated conditions was assessed. It was found that phorbol myristate acetate (PMA) stimulation increased GK rat macrophage ROS production 90-fold compared to basal levels. This response was also three times more pronounced than in control cells (36-fold). The production of pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α), tended to be upregulated in cultured macrophages from GK rats under basal conditions. Macrophages from GK rats produced 1.6 times more granulocyte-macrophage colony-stimulating factor (GM-CSF), 1.5 times more monocyte chemoattractant protein-1 (MCP-1) and 3.3 times more TNF-α than control cells when stimulated with lipopolysaccharide (LPS) (p = 0.0033; p = 0.049; p = 0.002, respectively). Moreover, compared to control cells, GK rats had 60% more M1 (p = 0.0008) and 23% less M2 (p = 0.038) macrophages. This study is the first to report macrophage inflammatory reprogramming towards a pro-inflammatory state in GK rats.

Assessing the responses to the application of photobiomodulation using red and infrared spectrum light-emitting diodes (LED) on diabetic foot ulcers. Diabetic volunteers, of both genders, aged between 30 and 65 years, with grade I or II ulcers, were randomized into the groups: red LED, infrared LED, LED associated, and control. Home-based interventions took place on a daily basis for 12 weeks. Assessments of sample characterization were performed on day 1 and 90, and the variables wound healing index, mean skin temperature, sensitivity and pain in the wound area were measured at the pre-intervention time on days 1, 30, 60 and 90, with subsequent follow-up 30 days after the end of treatment. For statistical analysis, the software SPSS, version 17.0, intention-to-treat analysis, data normality was tested, and the linear mixed effects model, with a significance level of 5%. Magnitudes of clinical effect by Cohen's d. At the pre vs post intervention time of 90 days, we found a large clinical effect of G-LED V (d=1.7) and G -LED IV (d=1.6) in relation to G-C, where these intervention groups showed a tendency for faster wound healing compared to G-C. We also observed small clinical effect of G-LED IV, which showed greater reduction in the area in relation to G-LED V (d=0.4) and G-LED A (d=0.3). Conclusion: The use of individually applied red and infrared LED phototherapy clinically tended to be more effective for the reduction of diabetic foot ulcer areas, and infrared LED was the most effective. Trial registration: NCT03250533 (clinicaltrials.gov).

Introduction: At the beginning of the COVID-19 pandemic, confinement measures were applied in many states around the world, producing changes in lifestyle and health habits, whose metabolic impact was different in different populations. Objectives: Describe the metabolic and anthropometric changes in office patients in the City of Córdoba during the confinement period and determine possible associated factors. Methods: Retrospective analytical observational study based on the review of the medical records of patients seen in an endocrinology clinic in Córdoba, Argentina. They were followed up during the 1-year period by evaluating metabolic and anthropometric characteristics. Results: 149 patients were included, of which 116 (77.9%) were female and the median:IQR age was 50:36.5-58 years. At the end of follow-up, a significant increase in alcohol consumption (18.1% vs 11.4%, p=0.001) was observed, as well as the number of diabetic patients (diagnosis of 20 new cases). 49.67% of patients increased their body weight, with a median of 3.1 kg (IQR 25-75%: 1.4-7.5 kg). Patients who had longer follow-up (3 or more controls during the year) decreased their Body Mass Index and increased physical activity. Conclusions: Although confinement was generally associated with an increase in obesity, diabetes and consumption of toxic substances, in patients who were monitored more frequently, better control of body weight and increased activity was observed. physical.

Se realizó el seguimiento de estos durante el período de 1 año evaluando características metabólicas y antropométricas. Resultados: Se incluyeron 149 pacientes, de los cuales 116(77,9%) eran de sexo femenino y la mediana:RIC de edad fue 50:36,5-58 años. Al final del seguimiento se observó un aumento significativo del consumo de alcohol (18,1% vs 11,4%, p=0,001), así como también el número de pacientes diabéticos (diagnóstico de 20 nuevos casos). El 49,67% de los pacientes incrementó su peso corporal, con una mediana de 3,1Kg(RIC 25-75%: 1,4-7,5 kg). Los pacientes que tuvieron mayor seguimiento (3 o más controles durante el año), disminuyeron su Índice de masa corporal y aumento de actividad física. Conclusiones: Si bien el confinamiento se asoció en términos generales a un aumento del obesidad, diabetes y consumo de sustancias tóxicas, en los pacientes a los cuales se les realizó un seguimiento más frecuente, se observó mejor control del peso corporal y aumento de la actividad física.

INTRODUCTION: Elevated plantar pressure (PP) constitutes a risk factor for developing foot ulcers. Once present, elevated PP increases morbidity and mortality in patients with diabetes. Given the high prevalence of overweight and obesity in the Mexican population, this study aimed to describe the magnitudes and the distribution of the PP observed in a sample of newly diagnosed patients with diabetes, adjusting for body mass index (BMI) groups (normal weight, overweight, grade I obesity, and grade II and III obesity). MATERIALS AND METHODS: A total of 250 volunteers attending a comprehensive care program for the management of type 2 diabetes received foot assessments that included vascular and neurological evaluation, the identification of musculoskeletal changes, and measurements of PP. RESULTS: Diabetic neuropathy and peripheral arterial disease were present in 21.6% and 11.2% of all participants. Musculoskeletal alterations were present in 70.8% of participants. A positive and significant correlation (p<0.001) was observed between BMI and the peak PP of all anatomical regions assessed. After adjusting for BMI, significant differences (p<0.001) were seen between groups. The metatarsal region, particularly under the third metatarsal head, denoted the highest magnitudes across all BMI. CONCLUSIONS: Periodic PP assessment is recommended to identify the distribution of high-pressure points along the plantar surface. However, as a preventive measure, it is suggested to encourage patients with diabetes and overweight or obesity to wear appropriate footwear and pressure-relief insoles to relieve high-pressure areas - often seen in these populations - to help prevent foot complications.

BACKGRUOUND: This study investigated the prognostic importance of the hemoglobin glycation index (HGI) for macrovascular and microvascular outcomes, mortality, and hypoglycemia occurrence in a type 2 diabetes cohort and compared it to glycated hemoglobin (HbA1c). METHODS: Baseline and mean first-year HGI and HbA1c, and the variability thereof, were assessed in 687 individuals with type 2 diabetes (median follow-up, 10.6 years). Multivariable Cox regression was conducted to evaluate the associations of HGI and HbA1c parameters with macrovascular (total and major cardiovascular events) and microvascular outcomes (microalbuminuria, advanced renal failure, retinopathy, and peripheral neuropathy), mortality (all-cause and cardiovascular), and moderate/severe hypoglycemia occurrence. RESULTS: During follow-up, there were 215 total cardiovascular events (176 major) and 269 all-cause deaths (131 cardiovascular). Microalbuminuria developed in 126 patients, renal failure in 104, retinopathy in 161, and neuropathy in 177. There were 90 hypoglycemia episodes. Both HGI and HbA1c predicted all adverse outcomes, except microalbuminuria and hypoglycemia. Their adjusted risks were roughly equivalent for all outcomes. For example, the adjusted hazard ratios (HRs) with 95% confidence intervals (CIs), estimated for 1 standard deviation increments, of mean first-year HGI were 1.23 (1.05 to 1.44), 1.20 (1.03 to 1.38), 1.36 (1.11 to 1.67), 1.28 (1.09 to 1.67), and 1.29 (1.09 to 1.54), respectively, for cardiovascular events, all-cause mortality, renal failure, retinopathy, and neuropathy; whereas the respective HRs (95% CIs) of mean HbA1c were 1.31 (1.12 to 1.53), 1.28 (1.11 to 1.48), 1.36 (1.11 to 1.67), 1.33 (1.14 to 1.55), and 1.29 (1.09 to 1.53). CONCLUSION: HGI was no better than HbA1c as a predictor of adverse outcomes in individuals with type 2 diabetes, and its clinical use cannot be currently advised.

Objective: To evaluate whether use of a culturally adapted mobile application (app) for adolescents with type 1 diabetes is associated with improved metabolic control. Methods: The Dominican Republic's National Institute of Diabetes, Endocrinology, and Nutrition and the Learning to Live clinic recruited 23 pediatric participants for the study. Blood tests were performed before and after use of the app for a period of 3 months. Based on the user profile, participants were encouraged to use the app's bolus insulin calculator after each meal. The app included a list of regionally and culturally specific foods, color-coded to indicate a high glycemic index (GI) as red; medium GI as yellow; and low GI as green. The color-coding was designed to assist participants in making healthier eating choices. Results: There were statistically significant improvements in lipid profile. Mean high-density lipoprotein values rose to acceptable levels, while low-density lipoproteins and triglyceride levels fell to the recommended values. The overall quality of life increased, although glycated hemoglobin levels showed no statistically significant changes. Conclusion: The findings of this study suggest that using this culturally tailored app can help young patients with type 1 diabetes to improve metabolic health.
RESUMEN
CONTEXT: Dietary interventions providing different amounts of carbohydrates have been proposed as a means of achieving glycemic control and weight loss in type 2 diabetes mellitus (T2DM); however, the supporting evidence is heterogeneous, making this recommendation difficult to apply in nutritional clinical practice. OBJECTIVE: The aim was to assess the quality of evidence from meta-analyses on low-carbohydrate (LC) dietary interventions for glycemic control, weight loss, and lipid profile in individuals with T2DM. DATA SOURCES: The MEDLINE, Web of Science, and Scopus databases were searched until September 2023. DATA EXTRACTION: A systematic review was conducted. Systematic reviews with meta-analysis of randomized clinical trials designed to assess glycated hemoglobin (HbA1c) reductions in individuals with T2DM were eligible. The AMSTAR-2 critical appraisal tool was used to evaluate the methodological aspects of all included studies. The GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach was used to assess the certainty of the evidence. DATA ANALYSIS: The LC interventions were associated with a reduction in HbA1c (%) of -0.42 (-1.45 to -0.09; high certainty of evidence) without considering follow-up time; at up to 3 months of follow-up of -0.28 (-0.13 to -0.43); at up to 6 months of follow-up of -0.40 (-0.61 to -0.09); at 6 to 12 months of follow-up of -0.32 (-0.49 to 0.11); and at >12 months of follow-up time of -0.31 (-0.14 to -0.65) compared with control diets. CONCLUSION: LC diets can help reduce HbA1c in individuals with T2DM in the short term (up to 3 months). However, dietary recommendations must always be individualized, as the studies reviewed herein analyzed different populations and used different definitions of what constitutes an LC diet. SYSTEMATIC REVIEW REGISTRATION: PROSPERO no. CRD42023404197.
RESUMEN
INTRODUCTION: Considering the relationship between Gestational Diabetes Mellitus and maternal and perinatal adverse outcomes, it's pertinent to investigate whether this diagnosis is a predictor of fear of childbirth. As there is little data about the fear of childbirth in Brazil, it´s necessary to understand better the population, and this way the authors can identify factors that influence this fear as well as propose public health policies to treat it. OBJECTIVE: The main goal was to compare the prevalence of fear of childbirth between the groups of low-risk pregnancy and gestational diabetes mellitus. MATERIAL AND METHODS: In this cohort study, the sample consisted of 319 patients divided into low-risk pregnancy group (n = 152) and gestational diabetes mellitus group (n = 167). Patients have undergone a semi-structured interview with epidemiological, obstetric, and anthropometric data and the main cause of fear of childbirth. In addition, the patients have marked an "X" on the scale into the Fear of Birth Scale to describe their fear. After delivery, data have been collected through electronic medical records. RESULTS: The prevalence of fear of childbirth found was higher for the gestational diabetes mellitus group (46.05%) compared to the low-risk pregnancy group (34.73%) with a cutoff score ≥ 54. In the whole sample, the main cause of fear of childbirth (score ≥ 60) was the pain of labor and delivery (31.58%). CONCLUSIONS: The prevalence of fear of childbirth in the present study was greater than 30%, highlighting the relevance of implementing this assessment during prenatal care.
