RESUMO
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.

RESUMO
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.
RESUMO
Prior investigation shows that diabetic patients present hypothalamus-pituitary-adrenal (HPA) axis hyperactivity related to impaired negative feedback. This study investigates the effect of Captopril on the overproduction of adrenocorticotropic hormone (ACTH) and its precursor proopiomelanocortin (POMC) in the pituitary gland of male diabetic mice. Diabetes was induced by intravenous injection of alloxan into fasted Swiss-webster mice, and the animals were treated with Captopril for 14 consecutive days, starting 7 days post-diabetes induction. Plasma corticosterone levels were evaluated by ELISA, while pituitary gland expressions of angiotensin-II type 1 receptor (AT1), angiotensin-II type 2 receptor (AT2), ACTH, Bax, Bcl-2, KI-67, POMC, and glucocorticoid receptor (GR) were evaluated using immunohistochemistry or Western blot. Diabetic mice showed pituitary gland overexpression of AT1, without altering AT2 levels, which were sensitive to Captopril treatment. Furthermore, diabetic mice presented hypercortisolism, along with an increase in the number of corticotroph cells, POMC and ACTH expression, and number of proliferative cells, and a decrease of GR expression in the pituitary gland. In addition, treatment with Captopril reduced systemic corticosterone levels, corticotroph and proliferative cell numbers, and Bcl-2, POMC, and ACTH expression in the pituitary gland of diabetic mice, besides increasing the expression of Bax and GR. In conclusion, these findings show that Captopril is a promising therapy for treating complications associated with HPA axis hyperactivity in diabetic patients, in a mechanism probably related to the downregulation of POMC production in the pituitary gland and subsequent reduction of systemic corticosterone levels.
RESUMO
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.
RESUMO
BACKGROUND: In-hospital hyperglycemia poses significant risks for patients with diabetes mellitus undergoing coronary artery bypass graft (CABG) surgery. Electronic glycemic management systems (eGMSs) like InsulinAPP offer promise in standardizing and improving glycemic control (GC) in these settings. This study evaluated the efficacy of the InsulinAPP protocol in optimizing GC and reducing adverse outcomes post-CABG. METHODS: This prospective, randomized, open-label study was conducted with 100 adult type 2 diabetes mellitus (T2DM) patients post-CABG surgery, who were randomized into two groups: conventional care (gCONV) and eGMS protocol (gAPP). The gAPP used InsulinAPP for insulin therapy management, whereas the gCONV received standard clinical care. The primary outcome was a composite of hospital-acquired infections, renal function deterioration, and symptomatic atrial arrhythmia. Secondary outcomes included GC, hypoglycemia incidence, hospital stay length, and costs. RESULTS: The gAPP achieved lower mean glucose levels (167.2 ± 42.5 mg/dL vs 188.7 ± 54.4 mg/dL; P = .040) and fewer patients-day with BG above 180 mg/dL (51.3% vs 74.8%, P = .011). The gAPP received an insulin regimen that included more prandial bolus and correction insulin (either bolus-correction or basal-bolus regimens) than the gCONV (90.3% vs 16.7%). The primary composite outcome occurred in 16% of gAPP patients compared with 58% in gCONV (P < .010). Hypoglycemia incidence was lower in the gAPP (4% vs 16%, P = .046). The gAPP protocol also resulted in shorter hospital stays and reduced costs. CONCLUSIONS: The InsulinAPP protocol effectively optimizes GC and reduces adverse outcomes in T2DM patients' post-CABG surgery, offering a cost-effective solution for inpatient diabetes management.
RESUMO
Goto-Kakizaki (GK) rats develop a well-defined insulin resistance (IR) and type 2 diabetes mellitus (T2DM) without presenting obesity. The lymphocyte profile in nonobese diabetic conditions is not yet characterized. Therefore, GK rats were chosen to explore T lymphocyte (TL) dynamics at various stages (21, 60, and 120 days) compared to Wistar rats. GK rats exhibit progressive disruption of glucose regulation, with early glucose intolerance at 21 days and reduced insulin sensitivity at 60 days, confirming IR. Glucose transporter 1 (GLUT1) expression was consistently elevated in GK rats, suggesting heightened TL activation. T-regulatory lymphocyte markers diminished at 21 days. However, GK rats showed increased Th1 markers and reduced Gata-3 expression (crucial for Th2 cell differentiation) at 120 days. These findings underscore an early breakdown of anti-inflammatory mechanisms in GK rats, indicating a proinflammatory TL profile that may worsen chronic inflammation in T2DM.
RESUMO
Introduction: Globally, up to 76.6% of the population may be affected by vitamin D (VD) deficiency, which has been linked to increased morbidity and mortality from COVID-19. This underscores the importance of further research into VD supplementation, particularly for health care workers, who are at higher risk due to indoor work environments and dietary challenges associated with shift schedules. Objective: This study aimed to identify factors associated with VD deficiency in Mexican health care workers exposed to SARS-CoV-2. Materials and methods: We conducted a cross-sectional study from June 2020 to January 2021 among frontline health care workers treating hospitalized COVID-19 patients. Blood samples were collected to measure 25-hydroxy VD levels via radioimmunoassay. We also assessed previous COVID-19 infection and comorbidities that could influence VD levels. Results: The study included 468 health care workers. The median serum VD concentration was 16.6 ng/mL. VD deficiency was found in 69.4% (n = 325) of participants, while only 5.1% (n = 24) had normal levels. Those with type 2 diabetes (13.3 ng/mL vs. 17.1 ng/mL) or obesity (15.7 ng/mL vs. 17.1 ng/mL) had significantly lower VD levels than their counterparts (p < 0.001 and p = 0.049, respectively). No significant differences were found among participants with high blood pressure. Multivariate analysis revealed that type 2 diabetes was independently associated with VD deficiency. Conclusion: There is a high prevalence of VD deficiency among health care workers, which is potentially linked to both personal health factors and occupational conditions.
RESUMO
The placenta plays an essential role in pregnancy, leading to proper fetal development and growth. As an organ with multiple physiological functions for both mother and fetus, it is a highly energetic and metabolically demanding tissue. Mitochondrial physiology plays a crucial role in the metabolism of this organ and thus any alteration leading to mitochondrial dysfunction has a severe outcome in the development of the fetus. Pregnancy-related pathological states with a mitochondrial dysfunction outcome include preeclampsia and gestational diabetes mellitus. In this review, we address the role of mitochondrial morphology, metabolism and physiology of the placenta during pregnancy, highlighting the roles of the cytotrophoblast and syncytiotrophoblast. We also describe the relationship between preeclampsia, gestational diabetes, gestational diabesity and pre-pregnancy maternal obesity with mitochondrial dysfunction.
RESUMO
BACKGROUND: Type 2 diabetes has economic implications involving family income and out-of-pocket spending. OBJECTIVE: Determine family out-of-pocket expenditure for type 2 diabetes mellitus care and percentage of family income. MATERIAL AND METHODS: Study of family out-of-pocket spending in families with patients with type 2 diabetes treated at primary care level. Out-of-pocket expenses included expenses for transportation, food-drinks, and external medications. Family income corresponded to the total economic income contributed by family members. The percentage of out-of-pocket spending in relation to family income was identified with the relationship between these two variables. Statistical analysis included averages and percentages. RESULTS: The annual family out-of-pocket expenditure on transportation was $2,621.24, the family out-of-pocket expenditure on food and beverages was $1,075.67, and the family out-of-pocket expenditure on external medications was $722.08. The total annual family out-of-pocket expense was $4,418.89 and corresponds to 4.73% of family income. CONCLUSION: The family out-of-pocket expense in the family with a patient with diabetes mellitus 2 was $4,418.89 and represents 4.73% of the family income.

This review explores the intricate connections between type 2 diabetes (T2D) and Parkinson's disease (PD), both prevalent chronic conditions that primarily affect the aging population. These diseases share common early biochemical pathways that contribute to tissue damage. This manuscript also systematically compiles potential shared cellular mechanisms between T2D and PD and discusses the literature on the utilization of antidiabetic drugs as potential therapeutic options for PD. This review encompasses studies investigating the experimental and clinical efficacy of antidiabetic drugs in the treatment of Parkinson's disease, along with the proposed mechanisms of action. The exploration of the benefits of antidiabetic drugs in PD presents a promising avenue for the treatment of this neurodegenerative disorder.
RESUMO
INTRODUCTION: Chronic hyperglycemia affects neutrophil functions, leading to reduced pathogen killing and increased morbidity. This impairment has been directly linked to increased glycemia, however, how this specifically affects neutrophils metabolism and their differentiation in the bone marrow is unclear and difficult to study. RESEARCH DESIGN AND METHODS: We used high-resolution respirometry to investigate the metabolism of resting and activated donor neutrophils, and flow cytometry to measure surface CD15 and CD11b expression. We then used HL-60 cells differentiated towards neutrophil-like cells in standard media and investigated the effect of doubling glucose concentration on differentiation metabolism. We measured the oxygen consumption rate (OCR), and the enzymatic activity of carnitine palmitoyl transferase 1 (CPT1) and citrate synthase during neutrophil-like differentiation. We compared the surface phenotype, functions, and OCR of neutrophil-like cells differentiated under both glucose concentrations. RESULTS: Donor neutrophils showed significant instability of CD11b and OCR after phorbol 12-myristate 13-acetate stimulation at 3 hours post-enrichment. During HL-60 neutrophil-like cell differentiation, there was a significant increase in surface CD15 and CD11b expression together with the loss of mitochondrial mass. Differentiated neutrophil-like cells also exhibited higher CD11b expression and were significantly more phagocytic. In higher glucose media, we measured a decrease in citrate synthase and CPT1 activities during neutrophil-like differentiation. CONCLUSIONS: HL-60 neutrophil-like differentiation recapitulated known molecular and metabolic features of human neutrophil differentiation. Increased glucose concentrations correlated with features described in hyperglycemic donor neutrophils including increased CD11b and phagocytosis. We used this model to describe metabolic features of neutrophil-like cell differentiation in hyperglycemia and show for the first time the downregulation of CPT1 and citrate synthase activity, independently of mitochondrial mass.

Advanced glycated end products (AGEs) are cytotoxic compounds that are mainly increased in diabetes mellitus (DM), kidney failure, inflammation, and in response to the ingestion of AGE-rich diets. AGEs can also impair glycemic homeostasis by decreasing the expression of the Slc2a4 (solute carrier family 2 member 4) gene and its GLUT4 (solute carrier family 2, facilitated glucose transporter member 4) protein in muscle. However, the mechanisms underlying AGE's effect on adipocytes have not been demonstrated yet. This study investigated the effects of AGEs upon Slc2a4/GLUT4 expression in 3T3-L1 adipocytes, as well as the potential role of NFKB (nuclear factor NF-kappa-B) activity in the effects observed. Adipocytes were cultured in the presence of control albumin (CA) or advanced glycated albumin (GA) at concentrations of 0.4, 3.6, and 5.4 mg/mL for 24 h or 72 h. Slc2a4, Rela, and Nfkb1mRNAs were measured by RT-qPCR, GLUT4, IKKA/B, and p50/p65 NFKB subunits using Western blotting, and p50/p65 binding into the Slc2a4 promoter was analyzed by chromatin immunoprecipitation (ChIP) assay. GA at 0.4 mg/mL increased Slc2a4/GLUT4 expression after 24 h and 72 h (from 50% to 100%), but at 5.4 mg/mL, Slc2a4/GLUT4 expression decreased at 72 h (by 50%). Rela and Nfkb1 expression increased after 24 h at all concentrations, but this effect was not observed at 72 h. Furthermore, 5.4 mg/mL of GA increased the p50/p65 nuclear content and binding into Slc2a4 at 72 h. In summary, this study reveals AGE-induced and NFKB-mediated repression of Slc2a4/GLUT4 expression. This can compromise the adipocyte glucose utilization, contributing not only to the worsening of glycemic control in DM subjects but also the impairment of glycemic homeostasis in non-DM subjects under the high intake of AGE-rich foods.

α-glucosidase, a pharmacological target for type 2 diabetes mellitus (T2DM), is present in the intestinal brush border membrane and catalyzes the hydrolysis of sugar linkages during carbohydrate digestion. Since α-glucosidase inhibitors (AGIs) modulate intestinal metabolism, they may influence oxidative stress and glycolysis inhibition, potentially addressing intestinal dysfunction associated with T2DM. Herein, we report on a study of an ortho-carbonyl substituted hydroquinone series, whose members differ only in the number and position of methyl groups on a common scaffold, on radical-scavenging activities (ORAC assay) and correlate them with some parameters obtained by density functional theory (DFT) analysis. These compounds' effect on enzymatic activity, their molecular modeling on α-glucosidase, and their impact on the mitochondrial respiration and glycolysis of the intestinal Caco-2 cell line were evaluated. Three groups of compounds, according their effects on the Caco-2 cells metabolism, were characterized: group A (compounds 2, 3, 5, 8, 9, and 10) reduces the glycolysis, group B (compounds 1 and 6) reduces the basal mitochondrial oxygen consumption rate (OCR) and increases the extracellular acidification rate (ECAR), suggesting that it induces a metabolic remodeling toward glycolysis, and group C (compounds 4 and 7) increases the glycolysis lacking effect on OCR. Compounds 5 and 10 were more potent as α-glucosidase inhibitors (AGIs) than acarbose, a well-known AGI with clinical use. Moreover, compound 5 was an OCR/ECAR inhibitor, and compound 10 was a dual agent, increasing the proton leak-driven OCR and inhibiting the maximal electron transport flux. Additionally, menadione-induced ROS production was prevented by compound 5 in Caco-2 cells. These results reveal that slight structural variations in a hydroquinone scaffold led to diverse antioxidant capability, α-glucosidase inhibition, and the regulation of mitochondrial bioenergetics in Caco-2 cells, which may be useful in the design of new drugs for T2DM and metabolic syndrome.

AIMS: To evaluate the prevalence of cardiovascular autonomic neuropathy (CAN) and its associated factors in Brazilian patients with type 1 diabetes (T1D). METHODS: This cross-sectional, multicentre study was conducted in 14 public clinics in ten Brazilian cities. From 1760 patients, 1712 were included (97.3â¯%): 953 females (55.7â¯%), 930 (54.3â¯%) Caucasians, aged 29.9 ±11.9 years and with diabetes duration of 15.4 ± 9.2 years. CAN was evaluated using cardiovascular autonomic reflex tests. RESULTS: The prevalence of CAN was 23.4â¯%. Multivariable hierarchical logistic regression showed CAN associated with age, smoking, lower socioeconomic status, higher yearly medical appointments, insulin therapeutic regimens, higher levels of HbA1c, total cholesterol, uric acid, diastolic blood pressure and heart rate, presence of retinopathy, diabetic kidney disease and a tendency to be associated with severe hypoglycemia. Lower health-related quality of life was also found in univariate analysis in these patients. CONCLUSIONS: Patients with T1D presented an important prevalence of CAN that was associated with other diabetes-related chronic complications, and also with demographic, clinical and laboratorial traditional risk factors. Considering lack of formal policy, our data could be used for guiding public health approach to awareness and CAN's screening, diagnosis and clinical management in patients with T1D in Brazil.

Introducción: La Enfermedad Renal Crónica ha cobrado interés debido a su alta tasa de morbimortalidad. Además de las causas vasculares y de la diabetes mellitus, se ha identificado una causa de Origen Desconocido en jóvenes agricultores. Objetivo: El objetivo del estudio es determinar la prevalencia de la población en hemodiálisis, sospechosa de la Nefritis Intersticial Crónica en Comunidades Agrícolas, para categorizar la verdadera etiología de su patología renal. Metodología: Se aplicó un diseño observacional descriptivo durante los meses de diciembre de 2022, enero y febrero de 2023; y se encuestó a 684 pacientes de ambos sexos en 8 centros de hemodiálisis de la Capital y el Departamento Central del Paraguay. Resultados: La prevalencia de casos sospechosos por la exposición a factores de riesgo resultó ser del 18.1%. Esta cifra podría ser mayor, ya que 22.6% de los pacientes con diabetes mellitus tipo 2, no presentó retinopatía clínica ni otros signos clínicos de la enfermedad al momento del diagnóstico de la falla renal. Este panorama nos advierte de un probable diagnóstico desacertado en una cantidad considerable de pacientes. Conclusión: La importancia de esta investigación se sustenta en generar acciones preventivas en la población agrícola y concientizar a la sociedad médica de la relevancia diagnóstica de esta patología para mejorar la calidad y pronóstico de vida en la población paraguaya.
Introduction: Chronic Kidney Disease has gained interest due to its high morbidity and mortality rate. In addition to vascular causes and diabetes mellitus, an unknown cause has been identified in young farmers. Objective: This study aims to determine the prevalence of the population on hemodialysis, suspected of Chronic Interstitial Nephritis in agricultural communities, to categorize the true etiology of their renal pathology. Methodology: A descriptive observational design was applied during December 2022, January, and February 2023; and 684 patients of both sexes were surveyed in 8 hemodialysis centers in the Capital and the Central Department of Paraguay. Results: The prevalence of suspected cases due to the exposure to risk factors was 18.1%. This figure could be higher since 22.6% of patients with type 2 diabetes mellitus did not present clinical retinopathy or other clinical signs of the disease at the time of the diagnosis of kidney failure. This scenario warns us of a probable misdiagnosis in a considerable number of patients. Conclusion: The importance of this research lies in generating preventive actions in the agricultural population and raising awareness in the medical community about the diagnostic relevance of this pathology to improve the quality and prognosis of life in the Paraguayan population.

Se caracteriza por placas inflamatorias amarronadas amarillentas con bordes indurados y centro atrófico, localizada en la cara anterior de las piernas. Tiene predominancia por el sexo femenino y su asociación con la diabetes es variable. Presentamos el caso de una mujer joven de 32 años, sin patologías previas, que desarrolla lesiones de apariencia cicatricial en ambos miembros inferiores tras accidente de tránsito. Se plantea el diagnóstico de necrobiosis lipoídica que se confirma por la anatomía patológica. Se inició tratamiento con corticoides, tacrolimus tópicos y se programa sesiones de fototerapia según evolución.
Necrobiosis Lipoídica (NL) is a chronic granulomatous disease of unknown etiology. It is characterized with yellowish-brown plaques with central skin atrophy and indurated borders. It has a predominance in female, and it has variable association with diabetes mellitus. We report a case of a young woman of 32 years old with no comorbities known but she did had a vehicular accident that leave her scars in both legs, therefore the plaques began to appear. We confirmed diagnosis with skin biopsy. She began treatment with topical corticosteroids, tacrolimus and phototerapy was schedule according to progress.
RESUMO
La diabetes mellitus postrasplante (DMPT) es una complicación que se encuentra de forma frecuente y se sucede al trasplante de órganos. Existen factores predisponentes a esta complicación, son varios y pueden estar presentes en el pretrasplante, peritrasplante o ya en el pos trasplante; dentro de estos, se resaltan las terapias inmunosupresoras asociadas. La importancia clínica de DMPT radica en su impacto para la enfermedad cardiovascular (ECV) y enfermedad renal crónica (ERC). En el presente artículo hacemos una revisión de las intervenciones tradicionales y las nuevas terapias para el manejo y tratamiento de la DMPT.
Post-transplant diabetes mellitus (PTDM) is a frequent complication after organ transplantation. There are several predisposing factors for this complication, which may be present in the pre-transplant, peri-transplant, or already post-transplant; within these, associated immunosuppressive therapies will be highlighted. The clinical importance of DMPT lies in its impact on cardiovascular disease (CVD) and chronic kidney disease (CKD). In this article, we review traditional interventions and new therapies for managing and treating PTDM.
RESUMO
Introduction: Obesity, age, sedentary lifestyle, and family history of diabetes mellitus are risk factors for type 2 diabetes mellitus (T2DM). Objective: determine the probable risk of developing T2DM in the next 10 years in working women at a reference hospital in Asunción, Paraguay. Methodology: This cross-sectional observational descriptive study was conducted with physicians, nurses, and administrative staff. Data were collected over three months using the FINDRISK test to assess diabetes risk, which consists of eight questions about age, body mass index, waist circumference, physical activity, fruit and vegetable consumption, history of blood pressure, high blood pressure and high glucose, and diabetes diagnosed in family members. Descriptive statistics in the form of frequencies and percentages, as well as analytical statistics using the Mann-Whitney and Kruskal-Wallis tests, were used to analyze the data. Results: A total of 112 women participated in the study, with more than 40% in the age range of 31-40 years. The waist circumference of 80-88 cm was the most common (38.4%). It was found that 33% of participants were overweight. Almost 60% of the participants did not perform daily physical activities. More than 38% of the first-degree relatives had a history of diabetes. Of the surveyed participants, 67.9%had some risk of developing T2DM in the next 10 years and 22 had a high or very high risk according to the FINDRISK test. Participants aged 35 years had a significantly higher risk (p=0.008). Conclusion: A high prevalence of overweight and obesity was observed, with 67.9% of the respondents showing some degree of risk for developing T2DM in the next 10 years, of which nearly 20% were categorized as high or very high risk.
Introducción: la obesidad, la edad, el estilo de vida sedentario y los antecedentes familiares de diabetes mellitus se han descrito como factores de riesgo para la diabetes mellitus tipo 2 (DM2). Objetivo: determinar el riesgo probable de desarrollar DM2 en los próximos 10 años en mujeres trabajadoras de un hospital de referencia en Asunción, Paraguay. Metodología: este estudio descriptivo observacional de corte transversal se llevó a cabo entre médicos, enfermeras y personal administrativo. Se recopilaron datos durante tres meses utilizando la prueba FINDRISK para evaluar el riesgo de diabetes, la cual consta de ocho preguntas sobre la edad, el índice de masa corporal, el perímetro de la cintura, la actividad física, el consumo de frutas y verduras, antecedentes de presión arterial alta y glucosa elevada, y diabetes diagnosticada en familiares. Para el análisis de los datos se utilizaron estadísticas descriptivas en forma de frecuencias y porcentajes, así como estadísticas analíticas con la prueba de Mann Whitney y Kruskal Wallis. Resultados: un total de 112 mujeres participaron en el estudio, con más del 40% en el rango de edad de 31 a 40 años. El perímetro de cintura de 80-88 cm. fue el más común, con 38,4%. Se encontró que el 33% de las participantes tenían sobrepeso. Casi el 60% no realizaba actividad física diaria. Más del 38% tenían antecedentes de diabetes en familiares de primer grado. El 67,9% de las encuestadas tenían algún riesgo de desarrollar DM2 en los próximos 10 años, y 22 de ellas presentaron un riesgo alto o muy alto según la prueba FINDRISK. Las participantes de 35 años o más tenían un riesgo significativamente mayor (Chi; p=0,008). Conclusión: se detectó una alta prevalencia de sobrepeso y obesidad, siendo el 67,9% de las encuestadas quienes mostraron algún grado de riesgo de desarrollar DM2 en los próximos 10 años, de los cuales casi el 20% presentaban un riesgo categorizado como alto o muy alto.
RESUMO
La cetoacidosis diabética constituye la manifestación extrema del déficit de insulina caracterizada por deshidratación, hiperglicemia, acidosis y cetosis. El tratamiento incluye soporte vital básico, hidratación parenteral para reposición de líquidos y electrolitos, insulinoterapia, con el objetivo de revertir la acidosis, la cetosis y obtener glucemia cercanas a lo normal. Exige un monitoreo estricto clínico y laboratorial siguiendo guías de manejo para evitar complicaciones y obtener una evolución favorable. Se presentan las modificaciones en las directrices publicadas en el Primer Consenso de diagnóstico y tratamiento de la Cetoacidosis diabética, en base a las actualizaciones sugeridas por la ISPAD (International Society of Pediatric and Adolescent Diabetes) y el Programa de Diabetes del Ministerio de Salud Pública y Bienestar Social (MSPBS).
Diabetic ketoacidosis is caused by extreme insulin deficiency and is characterized by dehydration, hyperglycemia, acidosis, and ketosis. Treatment includes basic life support, parenteral hydration to replace fluids and electrolytes and insulin therapy to reverse acidosis, ketosis, and normalize blood glucose levels. Management requires following guidelines for strict clinical and laboratory monitoring to avoid complications and obtain a favorable clinical outcome. The guidelines published in our previous Consensus on Diabetic Ketoacidosis diagnosis and treatment are presented, modified according to the latest changes in ISPAD (International Society of Pediatric and Adolescent Diabetes) and the Ministry of Public Health and Social Welfare Diabetes Program guidelines.
RESUMO
Resumen La presión arterial media es un indicador indirecto del grado de perfusión orgánica, la cual podría variar en pacientes con y sin diabetes mellitus-2. El objetivo fue determinar las diferencias y riesgo de alteraciones en la presión arterial media de adultos con y sin diabetes mellitus-2 de la población peruana según datos de la encuesta demográfica de salud familiar. Se realizó un estudio observacional, analítico, retrospectivo y transversal;. Los datos provinieron de la encuesta demográfica y de salud familiar-2022 (ENDES-2022), se incluyó adultos diabéticos y no diabéticos. Las variables fueron: presión arterial media, diabetes mellitus-2, sexo y se incluyeron las variables: edad, consumo de alcohol, nivel educativo e índice de masa corporal para el análisis multivariado. Se realizó la prueba de Chi-cuadrado de Pearson, la prueba T student para muestras independientes, Odds Ratio crudo y ajustado mediante regresión logística binaria. El promedio de presión arterial media en diabéticos fue de 94,81 y 93,52 mmHg en la primera y segunda medición y en no diabéticos de 89,18 y 88,02 mmHg. La presión arterial media alta fue más frecuente en diabéticos que en no diabéticos; En el modelo logístico, incluyendo las variables sexo y edad, los diabéticos tuvieron un riesgo 2 veces mayor que los no diabéticos de alteraciones en la presión arterial media tanto en la primera como en la segunda medición. En conclusión, la diabetes mellitus-2 incrementa la presión arterial media y representa un factor de riesgo para la elevación de la presión arterial media en la población peruana.
Abstract Mean arterial pressure is an indirect indicator of the degree of organ perfusion, which could vary in diabetics and non-diabetics. The objective of this research was to determine the differences and risk of alterations in the mean arterial pressure of adults with and without diabetes mellitus-2 of the Peruvian population according to data from the family health demographic survey. An observational, analytical, retrospective and cross-sectional study was carried out. The data came from the demographic and family health survey-2022 (ENDES-2022). Diabetic and non-diabetic adults were included. The variables were mean arterial pressure, diabetes mellitus-2, sex, and the variables age, alcohol consumption, educational level, and body mass index were included for multivariate analysis. Pearson's Chi-square test, student's T test for independent samples, crude Odds Ratio and adjusted by binary logistic regression were performed. The mean arterial pressure in diabetics was 94.81 and 93.52 mmHg in the first and second measurements, and in non-diabetics it was 89.18 and 88.02 mmHg. High mean arterial pressure was more frequent in diabetics than in non-diabetics. In the logistic model, including the variables sex and age, diabetics had a risk twice as high as non-diabetics for alterations in mean arterial pressure in both the first and second measurements. In conclusion, diabetes mellitus-2 increases mean arterial pressure and represents a risk factor for elevated mean arterial pressure in the Peruvian population.
