ABSTRACT
ABSTRACT Purpose: Trimethylamine N-oxide serum levels have been associated with type 2 diabetes mellitus and its complications. The current study aimed to find out if plasma trimethylamine N-oxide level may be a novel marker in the diagnosis of diabetic retinopathy and if it can be used in the differential diagnosis of diabetic and nondiabetic retinopathy. Methods: The study included 30 patients with diabetic retinopathy, 30 patients with nondiabetic retinopathy, 30 patients with type 2 diabetes mellitus without retinopathy, and 30 healthy control participants. Biochemical parameters, serum IL-6, TNF-α, and trimethylamine N-oxide levels were measured in all participants. Results: Trimethylamine N-oxide level was significantly higher in diabetic retinopathy than in the other groups (p<0.001). There was no significant difference in trimethylamine N-oxide levels between nondiabetic retinopathy and control or type 2 diabetes mellitus Groups. There was a significant positive correlation between trimethylamine N-oxide level and elevated FPG, BMI, HOMA-IR score, BUN, IL-6, and TNF-α levels. Conclusion: The current study showed that the trimethylamine N-oxide level is elevated in diabetic retinopathy. These findings suggest that serum trimethylamine N-oxide level might be a novel marker for diabetic retinopathy, and it might be used in the differential diagnosis of diabetic and nondiabetic retinopathy.
RESUMO Objetivo: Os níveis séricos de N-óxido de trimetilamina têm sido associados ao diabetes mellitus tipo 2 e suas complicações. O presente estudo tem como objetivo responder a duas questões, entre elas: O nível plasmático de N-óxido de trimetilamina poderia ser um novo marcador no diagnóstico de retinopatia diabética? e Ele poderia ser utilizado no diagnóstico diferencial de retinopatia diabética e não diabética? Métodos: Trinta pacientes com retinopatia diabética, 30 pacientes com retinopatia não diabética, 30 pacientes com diabetes mellitus tipo 2 sem retinopatia e 30 participantes saudáveis do grupo controle foram incluídos no estudo. Parâmetros bioquímicos, níveis séricos de IL-6, de TNF-α e de N-óxido de trimetilamina foram medidos em todos os participantes. Resultados: O nível de N-óxido de trimetilamina foi significativamente maior na retinopatia diabética do que nos outros grupos (p<0,001). Não houve diferença significativa no nível de N-óxido de trimetilamina entre o grupo de retinopatia não diabética, do grupo controle ou do grupo de diabetes mellitus tipo 2. Houve uma correlação positiva significativa entre o nível de N-óxido de trimetilamina e os níveis elevados de FPG, IMC, HOMA-IR, BUN, IL-6 e TNF-α. Conclusão: O estudo atual mostrou que o nível de N-óxido de trimetilamina encontra-se elevado na retinopatia diabética. Esses achados sugerem que o nível sérico de N-óxido de trimetilamina pode ser um novo marcador na retinopatia diabética, podendo ser usado no diagnóstico diferencial de retinopatia diabética e não diabética.
ABSTRACT
Abstract: Sarcopenia (the loss of muscle mass, strength and skeletal muscle function) increases mortality and the risk of hospitalization in the older population. Although it is known that older adults with type 2 diabetes mellitus (T2DM) have a higher risk of dynapenia and sarcopenia, few studies have investigated these conditions in middle-aged populations. The objective of this study was to investigate whether T2DM, its duration, the presence of albuminuria, and glycemic control are associated with sarcopenia and its components in adults. The cross-sectional analysis was based on data from visit 2 of the Brazilian Longitudinal Study of Adult Health (2012-2014). The 2018 European Working Group on Sarcopenia in Older People criteria were used to define dynapenia, low appendicular muscle mass (LAMM), and sarcopenia (absent/probable/confirmed). The explanatory variables were: T2DM; duration of T2DM; T2DM according to the presence of albuminuria; and glycemic control (HbA1C < 7%) among people with T2DM. A total of 12,132 participants (mean age = 55.5, SD: 8.9 years) were included. The odds ratio for LAMM was greater among those with T2DM, T2DM duration from 5 to 10 years, and T2DM without albuminuria. Chances of dynapenia were higher among those with T2DM, T2DM duration > 10 years, and T2DM with and without albuminuria. The variables T2DM, T2DM ≥ 10 years, and T2DM with albuminuria increased the odds of probable sarcopenia, and T2DM duration from 5 to 10 years increased the odds of confirmed sarcopenia. The results support the importance of frequently monitoring the musculoskeletal mass and strength of individuals with T2DM to prevent sarcopenia and related outcomes.
Resumo: A sarcopenia (perda de massa muscular, força e função muscular esquelética) aumenta a mortalidade e o risco de hospitalização em idosos. Idosos com diabetes mellitus tipo 2 (DMT2) apresentam risco elevado de desenvolver dinapenia e sarcopenia, mas poucos estudos investigaram populações de meia-idade. O objetivo foi investigar se DMT2, sua duração, a presença de albuminúria e o controle glicêmico estão associados à sarcopenia e seus componentes em adultos. Análise transversal baseada nos dados da segunda visita do Estudo Longitudinal de Saúde do Adulto (2012-2014). Os critérios do European Working Group on Sarcopenia in Older People [Grupo de Trabalho Europeu sobre Sarcopenia em Pessoas Idosas] de 2018 foram usados para definir dinapenia, baixa massa muscular apendicular e sarcopenia (ausente/provável/confirmada). As variáveis explicativas foram: DMT2; duração do DMT2; DMT2 de acordo com a presença de albuminúria; e controle glicêmico (HbA1c < 7%) entre pessoas com DMT2. Foram incluídos 12.132 participantes (idade média de 55,5; DP: 8,9 anos). A razão de chances para baixa massa muscular apendicular foi maior entre pessoas com DMT2, duração do DMT2 entre 5 e 10 anos e DMT2 sem albuminúria. As chances de dinapenia foram maiores entre pessoas com DMT2, duração do DMT2 > 10 anos e DMT2 com e sem albuminúria. DMT2, DMT2 ≥ 10 anos e DMT2 com albuminúria aumentaram as chances de sarcopenia provável e duração do DMT2 entre 5 e 10 anos aumentaram as chances de sarcopenia confirmada. Os resultados reforçam a importância do monitoramento frequente da massa e da força muscular em indivíduos com DMT2 para prevenir a sarcopenia e desfechos relacionados.
Resumen: La sarcopenia (pérdida de masa muscular, fuerza y función muscular esquelética) aumenta la mortalidad y el riesgo de hospitalización en ancianos. Los ancianos con diabetes mellitus tipo 2 (DMT2) presentan un mayor riesgo de sufrir dinapenia y sarcopenia, pero pocos estudios han investigado poblaciones de mediana edad. El objetivo fue investigar si la DMT2, su duración, la presencia de albuminuria y el control glucémico están asociados con la sarcopenia y sus componentes en adultos. Análisis transversal basado en los datos de la visita 2 del Estudio Longitudinal de Salud del Adulto en Brasil (2012-2014). Se utilizaron los criterios del European Working Group on Sarcopenia in Older People [Grupo de Trabajo Europeo sobre Sarcopenia en Personas Mayores] del 2018 para definir dinapenia, baja masa muscular apendicular y sarcopenia (ausente/probable/confirmada). Las variables explicativas fueron las siguientes: DMT2; duración de la DMT2; DMT2 según la presencia de albuminuria; y control glucémico (HbA1c < 7%) entre personas con DMT2. Se incluyeron 12.132 participantes (edad media = 55,5, DE: 8,9 años). La razón de probabilidades de masa muscular apendicular baja fue mayor entre personas con DMT2, duración de la DMT2 entre 5 y 10 años y DMT2 sin albuminuria. Las probabilidades de dinapenia fueron mayores entre las personas con DMT2, duración de la DMT2 > 10 años y DMT2 con y sin albuminuria. Las condiciones de DMT2, DMT2 ≥ 10 años y DMT2 con albuminuria aumentaron las probabilidades de sarcopenia probable y la duración de la DMT2 entre 5 y 10 años las probabilidades de sarcopenia confirmada. Los resultados refuerzan la importancia del monitoreo frecuente de la masa y de la fuerza musculoesquelética en individuos con DMT2 para prevenir la sarcopenia y los desenlaces relacionados.
ABSTRACT
Background: Scientific information on the impact of malaria on the risk of developing type 2 diabetes mellitus (T2DM) after recovery from the coronavirus disease 2019 (COVID-19) is limited in the Ghanaian context. The purpose of this study was to examine the association between selected risk markers of T2DM in falciparum malaria patients post-COVID-19 or not at a tertiary hospital in Ghana. Methodology: This was a descriptive cross-sectional comparative study of 38-recovered COVID-19 adult participants with malaria and 40 unexposed COVID-19 adults with malaria at the Tamale Teaching Hospital, Ghana. Demographic, anthropometric and levels of glucose, insulin, C-reactive protein and lipid profiles were measured in the two groups of participants under fasting conditions. Parasitaemia was assessed microscopically but insulin resistance and beta-cell function were assessed by the homeostatic model. Results: The COVID-19 exposed participants were older (p=0.035) with lower parasitaemia (p=0.025) but higher mean levels of insulin, insulin resistance, and beta-cell function compared with their unexposed counterparts (p<0.05). Parasitaemia correlated positively with a number of the measured indices of diabetogenic risk markers in the COVID-19 exposed group only, and predicted (Adjusted R2=0.751; p=0.031) by beta-cell function, C-reactive protein and triglycerides with the model explaining about 75% of the observed variation. Parasitaemia could only be predicted (Adjusted R2=0.245; p=0.002) by C-reactive protein with the model explaining just about a quarter of the observed variation in the COVID-19 unexposed group. Insulin resistance and sub-optimal beta-cell function were detected in both groups of participants. Conclusion: Falciparum malaria is associated with risk markers for development of T2DM irrespective of COVID-19 exposure. Insulin resistance, inflammation and sub-optimal beta-cell secretory function may drive the risk. The observed diabetogenic risk is higher in the recovered COVID-19 participants.

ObjectiveTo establish an ultra-high performance liquid chromatography-tandem triple quadrupole mass spectrometry（UHPLC-QqQ-MS） for determination of the active ingredients in Erdongtang， and to predict the targets and pathways of anti-insulin resistance action of this formula. MethodThe analysis was performed on an ACQUITY UPLC BEH C18 column（2.1 mm×100 mm， 1.7 μm） with the mobile phase of 0.1% formic acid aqueous solution（A）-acetonitrile（B） for gradient elution（0-3 min， 90%-87%A； 3-6 min， 87%-86%A； 6-9 min， 86%-83%A； 9-11 min， 83%-75%A； 11-18 min， 75%-70%A； 18-19 min， 70%-52%A； 19-22 min， 52%A； 22-25 min， 52%-5%A； 25-27 min， 5%-90%A； 27-30 min， 90%A）. The contents of active ingredients in Erdongtang was detected by electrospray ionization（ESI） and multiple reaction monitoring（MRM） mode under positive and negative ion modes. On this basis， network pharmacology was applied to predict the targets and pathways of Erdongtang exerting anti-insulin resistance effect. ResultThe 20 active ingredients in Erdongtang showed good linear relationships within a certain mass concentration range， and the precision， stability， repeatability and recovery rate were good. The results of determination showed that the ingredients with high content in 15 batches of samples were baicalein（1 259.39-1 635.78 mg·L-1）， baicalin（1 078.37-1 411.52 mg·L-1）， the ingredients with medium content were mangiferin（148.59-217.04 mg·L-1）， timosaponin BⅡ（245.10-604.89 mg·L-1）， quercetin-3-O-glucuronide（89.30-423.26 mg·L-1）， rutin（46.91-1 553.61 mg·L-1）， glycyrrhizic acid（55.97-391.47 mg·L-1）， neomangiferin（37.45-127.03 mg·L-1）， nuciferine（0.89-63.48 mg·L-1）， hyperoside（6.96-136.78 mg·L-1）， liquiritin（30.89-122.78 mg·L-1）， liquiritigenin（26.64-110.67 mg·L-1）， protodioscin（58.57-284.26 mg·L-1）， the ingredients with low content were wogonin（7.16-20.74 mg·L-1）， pseudoprotodioscin（5.49-22.96 mg·L-1）， ginsenoside Rb1（7.31-23.87 mg·L-1）， ginsenoside Rg1（10.78-28.33 mg·L-1）， ginsenoside Re（7.78-24.76 mg·L-1）， ophiopogonin D（2.08-4.29 mg·L-1）， methylophiopogonanone A（0.74-1.67 mg·L-1）. The results of network pharmacology indicated that the mechanism of anti-insulin resistance exerted by Erdongtang might be related to the phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway. ConclusionThe established UHPLC-QqQ-MS has the advantages of simple sample processing， strong exclusivity and high sensitivity， and can simultaneously determine the contents of the main ingredients from seven herbs in Erdongtang， which can lay the foundation for the development of Erdongtang compound preparations. The results of the network pharmacology can provide a reference for the mechanism study of Erdongtang in the treatment of type 2 diabetes mellitus.
ABSTRACT
Isoliquiritigenin (ISL) is an active chalcone compound isolated from licorice. It possesses anti-inflammatory and anti-oxidative activities. In our previous study, we uncovered a great potential of ISL in treatment of type 2 diabetes mellitus (T2DM). Therefore, this study aims to reveal the mechanism underlying the alleviatory effects of ISL on T2DM-induced glycolipid metabolism disorder. High-fat-high-sugar diet (HFD) combined with intraperitoneal injection of streptozotocin (STZ) were used to establish T2DM mice model. All animal experiments were carried out with approval of the Committee of Ethics at Beijing University of Chinese Medicine. HepG2 cells were used in in vitro experiments, and sodium palmitate (SP) was applied to establish insulin resistance (IR) model cells. The effects of ISL on body weight, fasting blood glucose levels, and pathological changes in the livers of mice were examined. Enzyme-linked immune sorbent assay (ELISA) and real-time quantitative PCR (RT-qPCR) were applied to detect the regulatory effects of ISL on key targets involved in glucolipid metabolism. Additionally, molecular docking and analytical dynamics simulation methods were used to analyze the interaction between ISL and key target protein. The results indicate that ISL significantly downregulates the transcriptional levels and inhibits the activities of key enzymes involved in gluconeogenesis, including pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), and fructose-1, 6-bisphosphatase (FBP). It also downregulates the transcriptional and protein levels of hepatocyte nuclear factor 4α (HNF4α) and cAMP response element binding protein (CREB), the two transcriptional factors involved in gluconeogenesis. Thus, ISL inhibits hepatic gluconeogenesis in T2DM mice. In addition, ISL reduces total cholesterol (TC) and triglyceride (TG) levels in the livers of T2DM mice. Moreover, ISL downregulates the mRNA levels of lipogenesis genes and upregulates those of genes involved in fatty acid oxidation, lipid uptake, and lipid export. In conclusion, ISL suppresses hepatic gluconeogenesis, promotes lipolysis, and restrains lipogenesis in T2DM mice, thereby improving the abnormal glycolipid metabolism caused by T2DM.
ABSTRACT
To develop a traditional Chinese medicine （TCM） diagnostic scale for type 2 diabetes mellitus with turbid-toxin accumulation syndrome and to validate the performance of the scale. A candidate pool was established through literature review and expert consultation， and a clinical case information collection form was developed accordingly. Patients with type 2 diabetes mellitus admitted to the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine from July 2021 to January 2022 were investigated， and 312 valid clinical case information collection forms were obtained， which were randomly divided into 235 cases in the study group and 77 cases in the validation group. Four statistical methods， namely， differentiation analysis， Cronbach's coefficient， correlation coefficient， and stepwise regression， were used to screen out the candidate items， and Logistic regression analysis and factor analysis were used to assign weights to the items， and the final diagnostic model was determined by the receiver operating characteristic （ROC） curve， and the diagnostic thresholds were calculated for the Yoden index. The final TCM diagnostic scale for type 2 diabetes mellitus was composed of 8 items： turbid dirt coating （with a weight value of 23， the same below）， sticky stools （16）， fullness in the epigastrium and abdomen （12）， dark complexion （12）， irritability （11）， brown spots on the skin （11）， heaviness of head （10）， and chest stuffiness （5）， and the degree score was 0， 0.5， 1.0， and 1.5 points corresponding to no， mild， moderate and severe symptoms， respectively. The total score was the sum of the degree score multiplied by the weighted value of each item， and when the total score reached 33 points， it is diagnosed as the turbid-toxin accumulation syndrome. The established scale was tested and evaluated in the study group and the validation group， and the results showed that the sensitivity of the study group and the validation group was 89.38% and 89.47%， with the specificity of 95.90% and 89.74%， the Yoden index of 0.85 and 0.79， the positive predictive value of 95.28% and 89.47%， the negative predictive value of 90.70% and 89.74%， the diagnostic advantage ratios of 198.18 and 72.67， and the Kappa values of 0.86 and 0.79， which indicated that the TCM diagnostic scale for turbid-toxin accumulation syndrome of type 2 diabetes mellitus showed good diagnostic ability.
ABSTRACT
ABSTRACT Background: Bile acids (BAs) are steroid molecules synthesized exclusively in the liver, being end products of cholesterol catabolism. BAs are known to be involved in several metabolic alterations, including metabolic syndrome and type 2 diabetes mellitus (DM2). DM2 is a chronic degenerative disease characterized by insulin resistance, insulin deficiency due to insufficient production of pancreatic ß-cells, and elevated serum glucose levels leading to multiple complications. Objective: The objective of this study is to investigate the role of BAs in the pathophysiology of DM2, highlighting the possibilities in the development of therapeutic procedures targeting BAs as an optional pathway in the treatment of DM2. Methods: The research was carried out through narrative review and publications on the relationship between BAs and DM2. The databases used for the search include PubMed, Scopus, and Web of Science. The keywords used for the search include bile acids, type 2 diabetes mellitus, metabolic syndrome, and metabolic disorders. Results: The studies have reported the involvement of BAs in the pathophysiology of DM2. BAs act as a ligand for the nuclear farnesoid X receptor, regulating glucose metabolism, lipid metabolism, and cellular energy production. Additionally, BAs modulate the production, elimination, and mobilization of BAs through the farnesoid X receptor. BAs also act as a signaling pathway through Takeda G protein-coupled receptor 5, further contributing to metabolic regulation. These findings suggest that targeting BAs may offer a novel therapeutic approach in the treatment of DM2. Conclusion: This study highlights the important role of BAs in DM2, specifically through their interactions with key metabolic pathways. Targeting BAs may represent an innovative and effective approach to the treatment of DM2.
RESUMO Contexto: Os ácidos biliares (ABs) são moléculas esteróides sintetizadas exclusivamente no fígado, sendo produtos finais do catabolismo do colesterol. Os ABs são conhecidos por estarem envolvidos em várias alterações metabólicas, incluindo a síndrome metabólica e o diabetes mellitus tipo 2 (DM2). A DM2 é uma doença crônica degenerativa caracterizada pela resistência insulínica, deficiência de insulina devido à produção insuficiente de células ß pancreáticas e hiperglicemia levando a múltiplas complicações. Objetivo: O objetivo deste estudo é investigar o papel dos ABs na fisiopatologia da DM2, destacando as possibilidades no desenvolvimento de procedimentos terapêuticos visando os ABs como uma via opcional no tratamento da DM2. Métodos: A pesquisa foi realizada por meio de revisão narrativa e publicações sobre a relação entre ABs e DM2. As bases de dados usadas para a pesquisa incluem PubMed, Scopus e Web of Science. As palavras-chave usadas para a pesquisa incluíram: ácidos biliares, diabetes mellitus tipo 2, síndrome metabólica e distúrbios metabólicos. Resultados: Os estudos relataram o envolvimento dos ABs na fisiopatologia da DM2. Os ABs atuam como ligantes para o receptor nuclear farnesoide X, regulando o metabolismo da glicose, metabolismo lipídico e produção de energia celular. Além disso, os ABs regulam a produção, eliminação e mobilização de ABs através do receptor farnesoide X. Os ABs também atuam como uma via de sinalização através do receptor acoplado à proteína G Takeda 5, contribuindo ainda mais para a regulação metabólica. Esses achados sugerem que o ABs pode oferecer uma nova abordagem terapêutica no tratamento da DM2. Conclusão: Este estudo destaca o papel importante do ABs na DM2, especificamente por meio de suas interações com vias metabólicas-chave. O redirecionamento ao ABs pode representar uma abordagem inovadora e eficaz para o tratamento da DM2.

Abstract Background: The concept of food addiction describes the difficulties of some individuals with regard to food consumption. Objective: To determine the frequency of food addiction and its association with body mass index (BMI), calorie consumption and therapeutic control in patients with newly-diagnosed type 2 diabetes mellitus (T2DM). Material and methods: A total of 1,080 patients with T2DM were included. The degree of metabolic control was determined with the levels of glycated hemoglobin, low-density lipoprotein cholesterol and blood pressure. Daily caloric consumption was estimated with a semi-quantitative questionnaire of food consumption frequency. Results: Nearly all patients showed overweight (40.5 %) and obesity (49.1 %). The frequency of food addiction was 54.2 % (56.9 % in women and 48.9 % in men). Food addiction was associated with BMI (OR = 1.89, p ≤ 0.05), high caloric intake (OR = 1.14, p ≤ 0.05) and glycated hemoglobin > 7 % (OR = 1.43, p ≤ 0.05) Conclusions: Food addiction is common in patients with overweight/obesity and newly-diagnosed T2DM, and is associated with higher-than-recommended caloric consumption, obesity degree and poor metabolic control.
ABSTRACT
SUMMARY: Middle cerebral artery (MCA), which has the largest irrigation area of the arteries that feed the brain, is an important artery whose microanatomy should be well known because of its vascular variation. In pathologies which are known to affect the cerebrovascular system such as type 2 diabetes mellitus (T2DM) and hypertension, morphometric characteristics of MCA gain importance. The aim of this study is to compare the morphometric characteristics of M1 segment of MCA in T2DM and hypertensive patients with those of healthy control group by using computed tomographic angiography (CTA). The study was carried out with retrospective morphometric analysis of CTA images of 200 individuals between 40 and 65 years of age. The individuals were grouped in four as hypertensive patients (group 1), patients with T2DM (group 2), patients with hypertension and T2DM (group 3) and healthy control group (group 4). Length and diameter measurements of M1 segment were performed and recorded by using 3D CTA images. While statistically significant difference was found between bilateral M1 segment diameters of both women and men (p0.05). As a result of the post hoc analysis performed, it was concluded that right and left M1 segment diameter of group 1, group 2 and group 3 was found to be different from group 4 in both sexes (p<0.05). We believe that this study will both be a guide in radio-anatomic assessments to be performed and also increase microanatomic level of information in the surgical treatment of the artery by showing the morphometric changes that occur in M1 segment of MCA in T2DM diseases.
La arteria cerebral media (ACM), que otorga la mayor área de irrigación de las arterias que alimentan el cerebro, es un vaso importante cuya microanatomía debe ser bien conocida por su variación vascular. En patologías que afectan al sistema cerebrovascular, como la diabetes mellitus tipo 2 (DM2) y la hipertensión, las características morfométricas de la ACM cobran importancia. El objetivo de este estudio fue comparar las características morfométricas del segmento M1 de la ACM en pacientes con DM2 e hipertensos con las del grupo control sano mediante el uso de angiografía por tomografía computada (TC). El estudio fue realizado através de análisis morfométrico retrospectivo de imágenes de TC de 200 individuos entre 40 y 65 años de edad. Los individuos fueron divididos en cuatro grupos, como pacientes hipertensos (grupo 1), pacientes con DM2 (grupo 2), pacientes con hipertensión y DM2 (grupo 3) y grupo control sano (grupo 4). Las mediciones de longitud y diámetro del segmento M1 se realizaron y registraron utilizando imágenes 3D TC. Si bien se encontraron diferencias estadísticamente significativas entre los diámetros bilaterales de los segmentos M1 de mujeres y hombres (p0,05). Como resultado del análisis post hoc realizado, se concluyó que el diámetro de los segmentos M1 derecho e izquierdo del grupo 1, grupo 2 y grupo 3 fue diferente del grupo 4 en ambos sexos (p<0.05). Creemos que este estudio será una guía en las evaluaciones anátomo-radiológicas y también mejorará el nivel de información microanatómica en el tratamiento quirúrgico al mostrar los cambios morfométricos que ocurren en el segmento M1 de la ACM en las enfermedades con DM2.

ABSTRACT
Objetivo: Determinar los hallazgos por ecografía Doppler arterial oftálmica en pacientes con enfermedad renal crónica avanzada. Métodos: Se efectuó un estudio observacional descriptivo y transversal con 212 órbitas de 106 pacientes con enfermedad renal crónica avanzada (estadios 4 y 5 en tratamiento dialítico). Por interrogatorio y examen físico se identificaron los factores de riesgo aterosclerótico. Además, se realizó ultrasonido orbitario y Doppler carotídeo, y solo en caso de resultar normales, se procedió a evaluar mediante ecografía Doppler las arterias oftálmicas. Resultados: Predominaron los pacientes mayores de 50 años, el sexo masculino, el color mestizo de piel y los normopesos; mientras que la hipertensión arterial, el tabaquismo y la diabetes mellitus tipo 2 fueron los factores de riesgo aterosclerótico mayoritarios. En todos los enfermos renales crónicos se demostró un incremento de la velocidad del flujo y de la resistencia vascular a nivel de las arterias oftálmicas, en tanto los casos con hipertensión arterial y diabetes mellitus tipo 2, así como los hipertensos exclusivos, mostraron los valores hemodinámicos más elevados. Conclusiones: La evaluación de las arterias oftálmicas mediante ecografía Doppler permite hacer un estudio y seguimiento más integral de los pacientes con enfermedad renal crónica avanzada.
Objective: To determine ophthalmic arterial Doppler ultrasound findings in patients with advanced chronic kidney disease. Methods: A descriptive and cross-sectional observational study was carried out with 212 orbits of 106 patients with advanced chronic kidney disease (stages 4 and 5 in dialysis treatment). Atherosclerotic risk factors were identified by interrogation and physical examination. In addition, orbital ultrasound and carotid Doppler were performed, and only if they were normal, the ophthalmic arteries were evaluated by Doppler ultrasound. Results: Patients older than 50 years, male sex, mestizo skin color and normal weight predominated, while arterial hypertension, smoking and type 2 diabetes mellitus were the main atherosclerotic risk factors. An increase in flow velocity and vascular resistance at the level of the ophthalmic arteries was demonstrated in all chronic renal patients, while cases with arterial hypertension and type 2 diabetes mellitus, as well as exclusive hypertensives, showed the highest hemodynamic values. Conclusions: The evaluation of the ophthalmic arteries by Doppler ultrasound allows a more comprehensive study and follow-up of patients with advanced chronic kidney disease.
ABSTRACT
ABSTRACT Type 2 diabetes mellitus (T2DM) is one of the most common chronic diseases worldwide and is highly prevalent in Mexico, as 10.2% of the adult population harbors this condition. T2DM is usually associated with cardiovascular comorbidities, including arrhythmias. Metabolic impairment is one of the mechanisms that contribute to tissue remodeling that affects atrial structure, and concomitant, the cardiac conduction system, both could result in atrial fibrillation (AF). AF is estimated to affect more than a half million Mexicans, and its incidence is expected to keep rising. According to national registries, T2DM is present in 28.4% of Mexican patients with AF and the coexistence of both diseases is associated with a higher risk of stroke. In clinical practice, the CHA2DS2-VASc risk score is useful for stroke risk stratification in patients with AF to facilitate the adequate use of anticoagulation therapy. T2DM is among the items of the CHA2DS2-VASc score because it correlates with an intrinsic prothrombotic state. In this narrative review, we present information that highlights the need for optimal glucose control and adequate anticoagulation in subjects with T2DM and AF.

Resumen Las enfermedades cardiovasculares constituyen la causa más común de mortalidad en el mundo. Actualmente, la diabetes mellitus tipo 2 (DM2) representa uno de los principales factores de riesgo de eventos adversos cardiovasculares mayores. Los pacientes que las padecen tienen un riesgo cuatro veces mayor de desarrollar insuficiencia cardíaca y una mortalidad de 10 a 12 veces mayor. La ecocardiografía en todas sus modalidades es la mejor herramienta clínica para el diagnóstico de la insuficiencia cardíaca, ya que proporciona imágenes estáticas y dinámicas del corazón que permiten identificar cambios estructurales y funcionales, como alteraciones en las presiones, cambios de flujo, fracción de expulsión del ventrículo izquierdo y remodelación anatómica de las superficies miocárdicas.
Abstract Cardiovascular diseases are the most common cause of mortality in the world. Currently, type 2 diabetes mellitus (T2DM) is one of the main risk factors for major adverse cardiovascular events. T2DM patients have a four-fold higher risk of developing heart failure and 10 to 12 times higher mortality. Echocardiography in all its modalities is the best clinical tool for heart failure diagnosis, since it provides static and dynamic images of the heart that allow to identify structural and functional changes, such as pressure variations, flow changes, left ventricular ejection fraction and myocardial surfaces anatomical remodeling.
ABSTRACT
Background: Secretory defects or defects in action of insulin precipitate a condition of chronic hyperglycemia known as diabetes mellitus, a metabolic disorder progressive in nature with long asymptomatic stage. Diabetic neuropathy is the most life threatening complication. Aims and Objectives: Early detection of peripheral neuropathy helps to take remedial measures in controlling the progression of the disease. Materials and Methods: Forty clinically detectable peripheral neuropathy Type 2 diabetic patients and 40 age-matched control subjects were selected for the study and nerve conduction test of ulnar sensory nerve was done and distal latency (DL), sensory nerve action potential (SNAP), and sensory nerve conduction velocity (SNCV) were recorded using RMS-EMG-EP-MAK II machine to predict the extent and type of neuropathy in diabetics. Results: Significant difference (P < 0.05) of DL, SNCV, and SNAP of ulnar sensory nerve was found in clinically detectable peripheral neuropathy group as compared to controls. Predominantly, axonal type (loss of amplitude) of neuropathy was present in study group. Conclusion: Electrophysiological variables of ulnar sensory nerve were affected in most of the subjects suggesting axonal loss and demyelinating changes in the nerve.
ABSTRACT
Background: Type-2 diabetes mellitus is related to decreased lung function. Prolonged inadequate control of glucose levels may alter regulation of inflammatory pathways that are implicated in pulmonary function complications. Aim and Objectives: The objjectives of the study were to assess the relationship of pulmonary function test (PFT) with factors influencing glycemic status in type 2 diabetes mellitus. Materials and Methods: A total of 110 diabetic cases with uncontrolled blood sugar levels and similar number age- and gender-matched control subjects above 30 years of age were recruited. Sociodemographic details were collected and participants underwent laboratory ad radiological investigations. PFTs including Forced vital capacity (FVC), peak expiratory flow rate (PEFR), forced expired volume in 1 s (FEV1), forced expiratory flow (FEF 25–75%), and FEV1/FVC ratio were assessed. Results: The comparison of PFTs with levels of HbA1c (<7 and >7) showed that the levels of FVC, PEFR, FEV1, and FEF 25–75% were higher in diabetics with HbA1c <7 and FEV1/FVC ratio was high in diabetic cases with HbA1c >7. The mean difference of PFT with HbA1c and body mass index (BMI) was statistically not significant in diabetics (P > 0.05). The person’s correlation analysis showed a negative correlation between FVC, FEV1 with HbA1c, and BMI in diabetics. Conclusion: Uncontrolled glycemic status and increased BMI were associated with functional impairment of lungs. Organized glycemic control and duly checking the PFTs may reduce the risk of onset of respiratory complications and lung function.
ABSTRACT
A serious health threat affecting the T2DM group is evident more cases T2DM are diagnosed. In this research, we choose to research into all of this possible mechanism of 3T3-L1 Cell lines and Molecular Docking studies Schrodinger software identified Vitamin D, Omega-3, and 6 PUFAs (EPA DHA & AA) Compounds of hydrophilic and hydrophobic pocket throughout molecular modeling besides T2DM. A group of three analog VDRs is being developed for discovery treatment with T2DM. Its use as it was agreed to run a molecular cell culture and docking study. Recognize the binding method involving the compound in T2DM through ADME prediction. The molecular dynamics simulation was enhanced by confirmation of the strength of the possible composite binding. Based on the computational results, the Omega-3 and 6 PUFAs compound encourages energy interaction. The composite contains an in vitro anti-diabetic activity; the compounds have clearly shown that they are active on T2DM. Our studies provide vital information on the findings of the bimolecular T2DM inhibitors.
