1, 25-(OH)2-VitD3 attenuates renal tubulointerstitial fibrosis in diabetic kidney disease by inhibiting Snail1-SMAD3/SMAD4 complex formation / 细胞与分子免疫学杂志

Objective To investigate the effect of 1, 25-(OH)2-VitD3 (VitD3) on renal tubuleinterstitial fibrosis in diabetic kidney disease. Methods NRK-52E renal tubular epithelial cells were divided into control group (5.5 mmol/L glucose medium treatment), high glucose group (25 mmol/L glucose medium treatment) and high glucose with added VitD3 group (25 mmol/L glucose medium combined with 10-8 mmol/L VitD3). The mRNA and protein expression of Snail1, SMAD3, SMAD4, α-SMA and E-cadherin in NRK-52E cells were detected by real-time quantitative PCR and Western blot analysis respectively. The expression and localization of Snail1, SMAD3 and SMAD4 were detected by immunofluorescence cytochemical staining. The binding of Snail1 with SMAD3/SMAD4 complex to the promoter of Coxsackie-adenovirus receptor (CAR) was detected by chromatin immunoprecipitation. The interaction among Snail1, SMAD3/SMAD4 and E-cadherin were detected by luciferase assay. Small interfering RNA (siRNA) was used to inhibit the expression of Snail1 and SMAD4, and the expression of mRNA of E-cadherin was detected by real-time quantitative PCR. SD rats were randomly divided into control group, DKD group and VitD3-treated group. DKD model was established by injection of streptozotocin (STZ) in DKD group and VitD3-treated group. After DKD modeling, VitD3-treated group was given VitD3 (60 ng/kg) intragastric administration. Control group and DKD group were given normal saline intragastric administration. In the DKD group and VitD3-treated group, insulin (1-2 U/kg) was injected subcutaneously to control blood glucose for 8 weeks. The mRNA and protein levels of Snail1, SMAD3, SMAD4, α-SMA and E-cadherin in renal tissues were detected by real-time quantitative PCR and Western blot analysis respectively. Immunohistochemistry was used to detect the expression and localization of Snail1, SMAD3, SMAD4, α-SMA and E-cadherin in renal tissue. Results Compared with the control group, the mRNA and protein expressions of Snail1, SMAD3, SMAD4 and α-SMA in NRK-52E cells cultured with high glucose and in DKD renal tissues were up-regulated, while E-cadherin expression was down-regulated. After the intervention of VitD3, the expression levels of Snail1, SMAD3, SMAD4, α-SMA and E-cadherin in the DKD model improved to be close to those in the control group. Chromatin immunoprecipitation showed that Snail1 and SMAD3/SMAD4 bound to CAR promoter IV, while VitD3 prevented Snail1 and SMAD3/SMAD4 from binding to CAR promoter IV. Luciferase assay confirmed the interaction among Snail1, SMAD3/SMAD4 and E-cadherin. After the mRNA of Snail1 and SMAD4 was inhibited by siRNA, the expression of E-cadherin induced by high glucose was up-regulated. Conclusion VitD3 could inhibit the formation of Snail1-SMAD3/SMAD4 complex and alleviate the renal tubulointerstitial fibrosis in DKD.

Long-term resveratrol administration improves diabetes-induced pancreatic oxidative stress, inflammatory status, and ß cell function in male rats

Abstract Diabetes is a metabolic disorder caused by insulin resistance or a defect in the pancreatic beta cells in insulin secretion. The aim of this study was to evaluate the possible effectiveness of long-term administration of resveratrol on inflammatory and oxidative stress markers in the pancreatic tissue of diabetic rats. Male Wistar rats (n = 24) were randomly divided into four groups of six animals, namely a healthy group, a healthy group receiving resveratrol, a diabetic control group, and a diabetic group receiving resveratrol. Diabetes was induced by single dose injection of streptozotocin (50 mg/kg; ip), 15 min after injection of nicotinamide (110 mg/kg; ip). Resveratrol was also administered by gavage (5 mg/kg/day) for 4 months. Administration of resveratrol alleviated hyperglycemia, weight loss and pancreatic ß cell function measured by HOMA-ß. Resveratrol improved oxidative stress (nitrate/nitrite, 8-isoprostane and glutathione) and proinflammatory markers (tumor necrosis factor α, cyclooxygenase 2, interleukin 6 and nuclear factor kappa B) in the pancreatic tissue of diabetic rats. Resveratrol administration had no significant effect on the activity of superoxide dismutase and catalase enzyme. These observations indicate that resveratrol administration may be effective as a beneficial factor in improving pancreatic function and reducing the complications of diabetes

Bioactivity-guided isolation of the antidiabetic principle in Pterocarpus Santalinoides leaf extract

Abstract Pterocarpus santalinoides is used in Nigerian ethnomedicine to treat diabetes mellitus. This study aimed to establish the antidiabetic property of the plant, and isolate and characterize its active principle. Dried and pulverized leaves (500 g) of P. santalinoides were extracted with 1.8 L of 80 % hydromethanol by cold maceration. The dried extract (10 g) was partitioned into n-hexane, ethyl acetate (EtOAc), n-butanol, and water. Antidiabetic activitiy-guided isolation by column chromatographic separation of the EtOAc soluble and purification of the sub-fractions by repeated preparative thin layer chromatography (pTLC) yielded a C-glycosyl flavonoid, identified as isovitexin. The chemical structure was elucidated based on high-resolution mass spectroscopy, 1D, and 2D nuclear magnetic resonance spectroscopic analyses. Alloxan-induced diabetic rat model was adopted for antidiabetic screening. The extract of P. santalinoides (100-200 mg/kg), fraction F4 (50 mg/kg), sub-fraction F4.3 (10 mg/kg), and the semi-purified compound F4.3.2 (5 mg/kg) significantly (p<0.05) reduced the fasting blood glucose of alloxan-induced diabetic rats, causing 48.4, 69.4, 57.7 and 64.5 % antidiabetic activity respectively, compared with > 68 % recorded in glibenclamide (2 mg/kg) control. These results reveal that isovitexin is the antidiabetic principle in P. santalinoides

Mucormicosis asociada a COVID-19: revisión de la literatura para odontólogos / COVID-19 associated mucormycosis: a literature review for dentists

La mucormicosis es una infección fúngica rara, con alta morbilidad y mortalidad. Se presenta principalmente en pa- cientes con diabetes mellitus no controlada, inmunocompro- metidos, con tratamiento crónicos con esteroides, entre otros. Actualmente, se cree que la pandemia de COVID-19 y los tratamientos con corticosteroides podrían estar implicados en el aumento de casos de esta micosis. Este hongo invade el sistema vascular, ocluyendo el flujo sanguíneo arterial y generando una rápida trombosis e isque- mia, lo que provoca la necrosis de los tejidos duros y blandos, con invasión rápida a los tejidos circundantes. Hay varias formas clínicas. En la cavidad bucal se presenta la variante rino-orbito-cerebral, que afecta el paladar en forma de lesión eritematosa o grisácea que puede progresar hacia la formación de una masa necrótica o ulceración con muy escaso sangrado de mucosa. Se manifiesta con síntomas típicos de una rinosinusitis con fiebre y dolor en las piezas dentarias superiores. El tratamiento consta de tres pilares fundamentales: el diagnóstico, un manejo adecuado de las comorbilidades y la combinación de las terapias antifúngica y quirúrgica. Desde el año 2020, la mucormicosis asociada a COVID-19 pasó a ser un evento de notificación obligatoria inmediata al Sistema Nacional de Vigilancia de la Salud (SNVS2.0) me- diante el Sistema Integrado de Información Sanitaria Argen- tina (SISA). Es importante destacar que se han reportado casos de mu- cormicosis luego de extracciones dentales; lo que impulsa a afianzar los conocimientos sobre esta enfermedad, extremar las medidas preventivas e incentivar el diagnóstico precoz en la atención odontológica, debido a la rapidez en la evolución de la patología (AU))

Mucormycosis is a rare fungal infection, with high mor- bidity and mortality. It occurs mainly in patients with uncon- trolled diabetes mellitus, immunocompromised, on chronic treatment with steroids, among others. Currently, it is believed that the COVID-19 pandemic and the corticosteroid treatments could be one of the causes of increased cases. This fungus invades the vascular system, occluding arteri- al blood flow and generating rapid thrombosis and ischemia, which causes necrosis of hard and soft tissues, with rapid in- vasion to the surrounding tissues. There are several clinical forms. In the oral cavity, the rhino-orbito-cerebral variant presents itself affecting the pal- ate in the form of an erythematous or grayish lesion that can progress towards the formation of a necrotic mass or ulcera- tion with very little mucosal bleeding. It manifests itself with typical symptoms of rhinosinusitis, with fever and pain in the upper teeth. The treatment consists of three fundamental pillars: diag- nosis, proper management of comorbidities and the combina- tion of antifungal and surgical therapies. Since 2020, COVID-19 associated mucormycosis became an event of mandatory immediate notification to the National Health Surveillance System (SNVS2.0,) through the Argentina Integrated Health Information System (SISA). It is important to emphasize that mucormycosis cases had been reported following tooth extractions, which drives to strengthen knowledge about this disease, extreme preventive measures and encourage early diagnosis in dental care, due to the speed of the evolution of the pathology (AU))

A study on diabetes-related self-care plan and its determinants among diabetes patients in a Warangal region, Telangana, India

Abstract The prevalence of epidemiological diseases, including diabetes, has continued to increase because of the adaption of Western culture and the lack of self-care activities among patients with diabetes. Therefore, in this cross-sectional study, we aimed to assess self-care plans and determinants among diabetes outpatients in Warangal. We conducted a prospective observational study among diabetes outpatient clinic in Warangal, India over 6 months from October 2019 to March 2020. We used the expanded Summary of Diabetes Self-Care Activities (SDSCA) questionnaire. A P value of less than < 0.05 was considered statistically significant. Respondents (mean age, 52.3 (standard deviation (SD), 11.01) years) had an overall SDSCA score of 49.18 ± 3.57 (SD). Mean scores for the diet, physical activity, foot care, medication adherence, and blood sugar testing scales were 12.79 (SD, 1.61), 10.24 (SD, 1.77), 15.67 (SD, 1.5), 5.66 (SD, 1.17), and 4.80 (SD, 0.68), respectively. Patients' age, education, disease duration and hemoglobin A1C (HbA1C) levels of <7.5% (P < 0.001)) had significantly higher mean scores for blood sugar testing, diet, physical activity, and adherence (P < 0.001). The employment status is associated with all the domains of Summary of Diabetes Self-Care Activities (P < 0.001). Taken together, our results revealed that patients with diabetes in Warangal had poor self-care planning, highlighting the need for strengthening initiatives that generate awareness regarding diabetes and improving related self-care practices

tiRNA-Val promotes angiogenesis via Sirt1-Hif-1α axis in mice with diabetic retinopathy

BACKGROUND: Diabetic retinopathy (DR) is a specific microvascular complication arising from diabetes, and its pathogenesis is not completely understood. tRNA-derived stress-induced RNAs (tiRNAs), a new type of small noncoding RNA generated by specific cleavage of tRNAs, has become a promising target for several diseases. However, the regulatory function of tiRNAs in DR and its detailed mechanism remain unknown. RESULTS: Here, we analyzed the tiRNA profiles of normal and DR retinal tissues. The expression level of tiRNA-Val was significantly upregulated in DR retinal tissues. Consistently, tiRNA-Val was upregulated in human retinal microvascular endothelial cells (HRMECs) under high glucose conditions. The overexpression of tiRNA-Val enhanced cell proliferation and inhibited cell apoptosis in HRMECs, but the knockdown of tiRNA-Val decreased cell proliferation and promoted cell apoptosis. Mechanistically, tiRNA-Val, derived from mature tRNA-Val with Ang cleavage, decreased Sirt1 expression level by interacting with sirt1 3'UTR, leading to the accumulation of Hif-1α, a key target for DR. In addition, subretinal injection of adeno-associated virus to knock down tiRNA-Val in DR mice ameliorated the symptoms of DR. CONCLUSION: tiRNA-Val enhance cell proliferation and inhibited cell apoptosis via Sirt1/Hif-1α pathway in HRMECs of DR retinal tissues.

Desenvolvimento de rota sintética da Rosiglitazona em processo batelada e microrreator capilar / Rosiglitazone synthetic route development in batch process and capillary microreactor

Para que os fármacos possam ser comercializados economicamente, a sua escala de produção deve ser aumentada para atender à demanda do mercado. Atualmente, a maior parte dos fármacos são sintetizados em processos batelada que possuem limitações quanto à eficiência de mistura, temperatura e pressão. O uso de microrreatores surge como alternativa na indústria químico-farmacêutica, aumentando a eficiência dos processos de maneira segura. Ferramentas utilizadas no segmento computacional multidisciplinar teórico, como o DFT (Density Functional Theory), podem prever e compreender o comportamento das reações químicas, podendo ter grande utilidade na síntese de novos fármacos economizando tempo, investimento e reduzindo a geração de resíduos. A diabetes mellitus é uma doença de caráter epidêmico, que a cada ano vem aumentando o número de casos. O emprego de fármacos derivados das glitazonas no tratamento de diabetes mellitus tipo 2 é recomendado devido ao excelente controle glicêmico que esta classe de fármacos oferece. Neste trabalho, foi sintetizada a Rosiglitazona, um fármaco derivado das glitazonas, que auxilia no tratamento da diabetes mellitus tipo 2, sendo estudadas duas rotas de síntese distintas, que foram otimizadas com o intuito de maximizar o rendimento de seus intermediários, obtendo a Rosiglitazona com pureza de cerca de 94%. Foi realizada, para os intermediários, aqui denominados, 1R, 2R2 e 3R2 a síntese one-pot e para os intermediários 1R, 2R1 e 3R2 foi realizada a transposição do processo usual em batelada para fluxo contínuo no microrreator, com rendimentos de até 93%. Com o auxílio da química quântica computacional, a reação de síntese do intermediário 1R, foi elucidada teoricamente e determinadas as grandezas termodinâmicas (ΔH‡, ΔG‡ e ΔS‡) no estado de transição, que foram comparadas com os valores experimentais, sendo constatada uma boa concordância, com desvio máximo de 14%

In order for drugs to be commercialized economically, their production scale must be increased to meet market demand. Currently, most drugs are synthesized in batch processes that have limitations in terms of mixing efficiency, temperature and pressure. The use of microreactors appears as an alternative in the chemical-pharmaceutical industry, increasing the efficiency of the synthesis processes in a safe way. Tools used in the theoretical multidisciplinary computational segment, such as DFT (Density Functional Theory), can predict and understand the behavior of chemical reactions, and can be very useful in the synthesis of new drugs, saving time, investment and reducing waste generation. Diabetes mellitus is an epidemic disease that has been increasing the number of cases every year. The use of drugs derived from glitazones in the treatment of type 2 diabetes mellitus is recommended due to the excellent glycemic control that this class of drugs offers. In this work, Rosiglitazone, a drug derived from glitazones, which helps in the treatment of type 2 diabetes mellitus, was synthesized. Two different synthetic routes were studied and optimized in order to maximize the yield of its intermediates, obtaining Rosiglitazone with purity of about 94%. One-pot synthesis was performed to 1R, 2R2 and 3R2 intermediates, and the transposition from the usual batch process to continuous flow in microreactor was performed to 1R, 2R1 and 3R2 intermediates, with yields of up to 93%. With the aid of computational quantum chemistry, the intermediate 1R synthesis reaction was theoretically elucidated and the thermodynamic properties were determined (ΔH‡, ΔG‡ and ΔS‡) in the transition state, which were compared with the experimental results, obtaining good agreement, with a maximum deviation of 14%.

Comparative study of cold hyperalgesia and mechanical allodynia in two animal models of neuropathic pain: different etiologies and distinct pathophysiological mechanisms

Abstract Neuropathic pain (NP) affects more than 8% of the global population. The proposed action of the transient receptor potential ankyrin 1 (TRPA1) as a mechanosensor and the characterization of the transient receptor potential melastatin 8 (TRPM8) as a cold thermosensor raises the question of whether these receptors are implicated in NP. Our study aimed to evaluate the involvement of TRPA1 and TRPM8 in cold and mechanical signal transduction to obtain a comparative view in rat models of streptozotocin-induced diabetes (STZ) and chronic constriction injury of the sciatic nerve (CCI). The electronic von Frey test showed that STZ rats presented mechanical allodynia that was first evidenced on the 14th day after diabetes confirmation, and four days after CCI. This phenomenon was reduced by the intraplantar (ipl) administration of a TRPA1 receptor antagonist (HC-030031; 40 µL/300 µg/paw) in both NP models. Only CCI rats displayed cold hyperalgesia based on the cold plate test. The pharmacological blocking of TRPA1 through the injection of the antagonist attenuated cold hyperalgesia in this NP model. STZ animals showed a reduction in the number of flinches induced by the intraplantar injection of mustard oil (MO; TRPA1 agonist; 0.1%/50 µL/paw), or intraplantar injection of menthol (MT; TRPM8 agonist; 0.5% and 1%/50 µL/paw). The response induced by the ipl administration of MT (1%/50 µL/paw) was significantly different between the CCI and SHAM groups. Together, these data suggest a different pattern in nociceptive behavior associated with different models of NP, suggesting a variant involvement of TRPA1 and TRPM8 in both conditions

Cannabis and cannabinoids as an alternative remedy in metabolic syndrome

Abstract Metabolic syndrome (MetS), an epidemic defined as a group of interconnected physiological, biochemistry, clinical, and metabolic factors, directly increases the risk of cardiovascular disease, atherosclerosis, type 2 diabetes, and death. MetS therapy includes diet, physical exercise, and a poly-pharmacological intervention. Cannabis is mainly recognized for its recreational uses and has several medical applications for neurological diseases, due to its hypnotic, anxiolytic, antinociceptive, anti-inflammatory, and anticonvulsant activities. Although several clinical observations in Cannabis smokers suggest metabolic effects, its utility in metabolic disorders is unclear. This review aims to determine under what conditions Cannabis might be useful in the treatment of MetS. Cannabis contains 120 phytocannabinoids, of which Δ9-THC mediates its psychoactive effects. Cannabinoids exert biological effects through interactions with the endocannabinoid system, which modulates several physiologic and metabolic pathways through cannabinoid receptors (CB1/CB2). Signaling through both receptors inhibits neurotransmitter release. In general, endocannabinoid system stimulation in Cannabis smokers and Δ9-THC signaling through CB1 have been implicated in MetS development, obesity, and type 2 diabetes. In contrast, CB1 antagonists and non-psychotropic phytocannabinoids like cannabidiol reduce these effects through interactions with both cannabinoid and non-cannabinoid receptors. These pharmacological approaches represent a source of new therapeutic agents for MetS. However, more studies are necessary to support the therapeutic potential of Cannabis and cannabinoids in metabolic abnormalities

Knowledge about the disease and adherence to treatment in patients with diabetes

Introduction: Glycemic decompensation in diabetes is one of the major factors for the development of chronic disease complications. Factors involved in the adequate control of diabetes include adherence to pharmacological treatment and knowledge about the disease.Methods: Cross-sectional study on the factors associated with adherence to drug treatment and knowledge about diabetes in diabetic patients treated at Hospital Universitário de Santa Maria between 2018 and 2019, based on the validated Morisky-Green test and on the Diabetes Knowledge Questionnaire.Results: A total of 201 patients diagnosed with diabetes were included, the majority (85.6%) of which had type 2 diabetes and were white (75.6%), with a mean age of 59.4 years. An association between insufficient knowledge about diabetes and patients with type 2 diabetes was observed. An association was found between patients with type 2 diabetes using insulin and non-adherence to drug treatment compared with patients with type 2 diabetes who did use insulin. The research also showed that non-adherence to drug treatment was associated with higher occurrence of hypoglycemia compared with patients who adhered to drug treatment.Conclusion: The data obtained in our study allows us to conclude that non-adherence to pharmacological treatment makes diabetes therapy more complicated and worsens the prognosis.

Manejo odontológico del paciente diabético: revisión narrativa / Dental management of the diabetic patient. Narrative review

La diabetes mellitus es una enfermedad metabólica caracterizada por altos niveles de glucosa en sangre y defectos en la producción y/o la acción de la insulina. La hiperglucemia crónica puede derivar en complicaciones metabólicas y vasculares como micro- y macroangiopatías y alteraciones en el metabolismo de lípidos y proteínas. Los pacientes diabéticos mal controlados o no controlados presentan signos y síntomas evidenciables a nivel bucal. En el mundo, alrededor del 8,8% de los adultos de entre 20 y 79 años padecen este trastorno endócrino, y se estima que para el año 2045 unos 629 millones de personas de este rango etario tendrán diabetes. Por ello, es fundamental que el odontólogo se encuentre familiarizado con el manejo médico de estos pacientes, a fin de estar preparado para brindarles un tratamiento adecuado y responder a las emergencias médicas que se presenten durante su atención. En esta revisión se emplearon resultados extraídos manualmente de artículos indexados en las bases de datos MEDLINE y EBSCO que responden a la búsqueda de los términos diabetes mellitus, dental management, oral surgery y HbA1c, con el objetivo de describir el manejo médico-odontológico del paciente diabético hasta la fecha (AU)

Diabetes Mellitus is a metabolic disease characterized by high blood glucose levels and defects in the production and/or the use of insulin. Chronic hyperglycemia can lead to metabolic and vascular complications. Vascular complications include micro and macroangiopathies. The metabolic disorders are: alterations of lipid and protein metabolism. Patients with poorly controlled or uncontrolled diabetes present symptoms that are evident in the oral cavity. Around 8.8% of adults between 20-79 years old, worldwide, have this endocrine disorder and it is estimated that by 2045, 629 million people in this age group, will have diabetes. Therefore, it is essential for dentists to be familiar with the medical management of these patients, in order to provide adequate treatment and eventual management of medical emergencies that may occur during dental treatment. The present review used data extracted manually from articles indexed in the MEDLINE and EBSCO databases, using the terms: Diabetes mellitus, Dental Management, Oral Surgery and HbA1c. The following article aims to describe the medical/dental management of the diabetic patient updated to date (AU)

Antidiabetic activities of alkaloids isolated from medicinal plants

Diabetes mellitus is a metabolic disorder affecting a great part of population around the world. It is the fifth leading death causing disease in the world and its cases are increasing day by day. Traditional medicine is thought to have promising future in the treatment of diabetes mellitus. In contrast to synthetic drugs phytochemicals are considered to be free from side effects. As one of the main class of natural products, alkaloids and their derivatives have been widely used as sources of pharmacological agents against a variety of medical problems. Many studies confirmed the role of alkaloids in the management of diabetes and numerous alkaloids isolated from different medicinal plants were found active against diabetes. Like other natural products, alkaloids regulate glucose metabolism either by inhibiting or inducing multiple candidate proteins including AMP-activated protein kinase, glucose transporters, glycogen synthase kinase-3, sterol regulatory element-binding proteins 1, glucokinase, glucose-6-phosphatase, acetyl-CoA carboxylase among the others. A comprehensive review of alkaloids reported in the literature with anti-diabetic activities and their target enzymes is conducted, with the aim to help in exploring the use of alkaloids as anti-diabetic agents. Future work should focus on rigorous clinical studies of the alkaloids, their development and relevant drug targets.

Pielonefritis Enfisematosa. Reporte de dos casos / Emphysematous pyelonephritis. Report of two cases

RESUMEN La pielonefritis enfisematosa se considerada una entidad clínica inusual. Constituye una infección necrotizante aguda, con formación de gas en el parénquima renal, sistema colector y/o espacio perirrenal. La población diabética es más propensa a este tipo de pielonefritis, pero se han descrito casos de pielonefritis enfisematosa recurrente en pacientes con obstrucción de la vía urinaria en ausencia de diabetes mellitus. Del 69 al 97 % de los casos, el germen implicado en la génesis de la enfermedad es la Escherichia coli, seguido por la klebsiella pneumoniae; responsable de una enfermedad con alto impacto en la morbimortalidad de los pacientes diabéticos. El conocer esta entidad clínica, permite realizar un diagnóstico precoz con el fin de establecer el tratamiento más adecuado que contribuya a una mejor sobrevida en el paciente. Los estudios tomográficos orientan en el diagnóstico, facilitan tener la opción de un tratamiento conservador y cuando lo requiera un correcto tratamiento invasivo, que debe ser individualizado según la posible causa que lo genera (AU).

ABSTRACT Emphysematous pyelonephritis is considered an unusual clinical entity. It is an acute necrotizing infection, with gas formation in the renal parenchyma, the collector system and/or perinephric space. Diabetic population is more prone to this kind of pyelonephritis, but cases of emphysematous pyelonephritis have been described in patients with urinary tract obstruction in absence of Diabetes mellitus. On 69 to 97 % of the cases, the germ implied in the disease genesis is Escherichia coli, followed by Klebsiella pneumonia, that are responsible for a disease having a high impact on the diabetic patients´ morbidity and mortality. Knowing this clinical entity allows arriving to a precocious diagnosis with the aim of establishing the most suitable treatment contributing to a better patients´ survival. Tomographic studies guide in the diagnosis, facilitate the option of a conserving treatment, and when it is required a correct invasive treatment individualized according to the possible cause generating it (AU).

Clinacanthus nutans: Its potential against diabetic vascular diseases

Diabetes is an independent risk factor for the development of cardiovascular disease, with approximately 80% of cardiovascular mortality and morbidity linked to vascular complications such as atherosclerosis. It has been estimated that up to one-third of patients with diabetes mellitus use some form of complementary and/or alternative medicine. One plant that has received attention from diabetic patients for its perceived antidiabetic properties is Clinacanthus nutans, a member of the Acanthaceae family that is known as snake grass. Ethnomedical applications of this herb have been identified for the treatment of certain conditions, including fever, diabetes, skin rashes, and insect bites. This review aims to assess the potential of C. nutans to be used in the prevention and/or treatment of diabetic vasculopathy. Evidence for antidiabetic, anti-inflammatory, and dyslipidemic properties of C. nutans, as shown from experimental studies, is presented and discussed. Diabetes, inflammation, and hyperlipidemia are known to play significant roles in the initiation and severity of diabetic cardiovascular disease; thus, targeting these factors might be beneficial for preventing and/or treating diabetic vasculopathy.

Exploring the shared genes of hypertension, diabetes and hyperlipidemia based on microarray

Given their relationship with metabolic syndrome and systematic inflammatory diseases, the pathogenesis of hypertension, hyperglycemia, and hyperlipidemia is closely related. To explore the common genes among these three conditions, spontaneous hypertensive rats (SHR), spontaneous diabetic Goto-Kakizaki rats (GK) and hyperlipidemia rats (HMR) were reared for experiments. Gene array was used to identify the genes of SHR, GK and HMR compared with normal Wistar rats using TBtools software. First, real-time PCR was applied to verify these genes, and Cytoscape software was used to construct networks based on the National Center for Biotechnology Information (NCBI) database. Second, Kyoto Encyclopedia of Genes and Genomes (KEGG) database analysis was performed to classify the genes. Visualization and Integrated Discovery (DAVID) database and Gene Ontology database were used to explore the biological function. Finally, Onto-tools Pathway Express was used to analyze the pathways of shared genes. Importantly, upregulated common genes, such as Bad, Orm1, Arntl and Zbtb7a, were used to construct a network of 150 genes, while downregulated genes, such as Mif and Gpx1, formed a network of 29 genes. Interestingly, the networks were involved in various pathways, such as insulin signal pathway, endometrial cancer pathway, circadian rhythm pathway, and pancreatic cancer pathway. We discovered common genes of SHR, GK and HMR compared with normal Wistar rats, and the association of these genes together with biological function were preliminarily revealed.

Diabetes as a risk factor of acute kidney injury in vancomycin users: an observational and prospective study

Diabetes was investigated as a risk factor for nephrotoxicity induced by vancomycin. In the present study, the drug's nephrotoxic effect was indirectly evaluated by Glomerular Filtration Rate, albuminuria and serum levels of creatinine and urea on the 1st, 7th and 14th days of vancomicyn therapy in a group of diabetic and non-diabetic patients, with and without previous nephropathy. The correlations between investigated variables (including the population's epidemiological profile and hospital care) were measured by the Spearman test. The sample consisted of 132 patients, predominantly male diabetic patients with previous nephropathy, over 40 years, receiving ≥ 10 grams of vancomycin for the treatment of infectious diseases and showing satisfactory clinical outcomes. A risk of vancomycin drug interaction with potential nephrotoxic outcome was observed in 36.4% of patients who used multiple drugs. Furthermore, 80% of patients had an increase of at least 0.5 mg.dL-1 in baseline serum levels of creatinine and urea at the end of the study. This was more common among the diabetic patients with previous nephropathy, showing higher albuminuria and a reduction in the Glomerular Filtration Rate. Therefore, it has been recommended that the use of vancomycin in diabetic patients should be in careful dosages and that kidney functioning be monitored.

Educación terapéutica en pacientes con diabetes y trastornos emocionales / Terapeutic education in patients with diabetes and emotional disorders

La diabetes mellitus (DM) se considera como un conjunto de trastornos metabólicos relacionados con la hiperglucemia, que requiere cambios en estilos de vida, en virtud de que no solo se afecta el estado físico, sino que requiere cambios que pueden influir en el estado emocional y psicosocial. Las personas con diabetes requieren de cuidados continuos orientados al control metabólico centrados en el empoderamiento, autocuidado y en la educación terapéutica para alcanzar metas y resultados orientados a minimizar la aparición de las complicaciones crónicas. Objetivo: analizar la importancia de la educación terapéutica en los pacientes con trastornos afectivos como depresión y ansiedad, asociados a la diabetes. Conclusión: la educación terapéutica como parte integral del tratamiento de la DM ha demostrado mejorar los síntomas asociados a depresión y ansiedad, lo cual podría adquirir un valor importante en el manejo de este grupo de pacientes(AU)

Diabetes mellitus (DM) is considered as a set of metabolic disorders related to hyperglycemia, which requires changes in lifestyle, because not only physical condition is affected, but it also requires changes that can influence emotional state and psychosocial.

Objective: to analyze the importance of therapeutic education in patients with affective disorders such as depression and anxiety, associated with diabetes. Conclusion: therapeutic education as an integral part of the treatment of DM has been shown to improve symptoms associated with depression and anxiety, which could acquire an important value in the management of this group of patients(AU)

Consumo de azúcar añadido en la población urbana costarricense: estudio latinoamericano de nutrición y salud ELANS-Costa Rica / Added sugar intake in a Costa Rican urban population: Latin American nutrition and health study ELANS-Costa Rica

Resumen Objetivo : El objetivo del estudio fue analizar el consumo de azúcares añadidos por la población urbana costarricense y los factores asociados a este. Método: Estudio transversal donde se analizan los datos de 798 participantes del Estudio ELANS-Costa Rica, que constituyen una muestra representativa de la población urbana costarricense, (con edades entre 15 y 65 años). Para conocer el consumo de azúcares añadidos, se realizan dos recordatorios de 24 horas, en días no consecutivos. Se recolectan variables sociodemográficas, cantidad, lugar y momento del consumo. Resultados: El consumo de azúcares añadidos representa el 14,7% de la energía consumida por la población urbana costarricense, siendo este porcentaje mayor en las mujeres y en las personas más jóvenes. La mayor cantidad de azúcares añadidos se consume en el hogar y durante las meriendas. Las bebidas azucaradas constituyen la principal fuente de azúcares añadidos en la dieta costarricense, y las bebidas gaseosas son la fuente más importante en el quintil de mayor consumo. Conclusión: La ingesta de energía obtenida de los azúcares añadidos supera la recomendación máxima establecida por la Organización Mundial de la Salud, por lo tanto, es necesario establecer políticas públicas dirigidas a reducir su consumo y a la modificación de conductas asociadas a la preparación e ingesta de alimentos fuente de azúcares añadidos.

Abstract Aim: High consumption of added sugars has been associated with a greater risk of chronic diseases, appearance of caries and weight gain, which implies a lower quality of life for the population and an increase in costs for the health system. The aim of this study was to evaluate the intake of added sugar and its related factors in urban Costa Rican population. Methods : This was a cross-sectional study conducted in a representative sample of the Costa Rican urban population (798 participants aged between 15 and 65 years). To determine the consumption of added sugars, two 24 hours recalls were conducted, in non-consecutive days. Sociodemographic variables, quantity of food consumed, place and time of consumption were collected. Results: The consumption of added sugars represents 14.7% of total energy intake for the Costa Rican urban population. This consumption is higher among women and younger people. The greater amount of added sugars was consumed in the home and during snacks. Sugar-sweetened beverages were the main source of this added sugar in the Costa Rican diet and soft drinks were the most important source in the highest consumption quintile. Conclusions: The intake of energy obtained from the added sugars exceeds the máximum recommendation established by the World Health Organization, therefore it is necessary to establish public policies aimed at reducing consumption and modifying behaviors associated with the preparation and intake of food source of added sugars.

Enfermedad periodontal y su implicancia en la diabetes mellitus: revisión de la literatura / Periodontal disease and its implication in diabetes mellitus: a review of the literature

La enfermedad periodontal es una infección mixta, causada por bacterias periodonto-patógenas que conforman la placa subgingival, se caracteriza por inflamación crónica y destrucción progresiva del aparato de soporte dentario. La lesión característica es la bolsa periodontal, cuyo epitelio ulcerado permitiría el pasaje de bacterias y sus factores de virulencia, toxinas, enzimas y mediadores inflamatorios hacia la circulación general. Este proceso inflamatorio crónico localizado en la cavidad oral puede activar también, la respuesta inflamatoria a nivel sistémico. La periodontitis es un factor de riesgo en el origen y evolución de numerosas enfermedades crónicas sistémicas, como la diabetes mellitus; trastorno endocrino caracterizado por hiperglucemia, hiperinsulinemia, y resistencia a la insulina. Los efectos perjudiciales de las infecciones periodontales sobre la diabetes se explican por el aumento de mediadores proinflamatorios sistémicos, lo que agravaría el estado de resistencia a la insulina, considerando estos pacientes con afectación periodontal como pacientes sistémicamente comprometidos. La diabetes mellitus y la periodontitis comparten una evolución compleja y, entre ellas, se constituye una relación bidireccional. El objetivo de esta revisión es proporcionar una visión actual sobre procesos moleculares y celulares que vinculan a la enfermedad periodontal e inflamación crónica con la diabetes mellitus (AU)

Periodontal Disease is a mixed infection, caused by periodontopathogenic bacteria that make up the subgingival plaque, characterized by chronic inflammation and progressive destruction of the dental support apparatus. The characteristic lesion is the periodontal pocket whose ulcerated epithelium would allow the passage of bacteria and their virulence factors, toxins, enzymes and inflammatory mediators into the general circulation. This chronic inflammatory process located in the oral cavity can also activate the inflammatory response at the systemic level. Periodontitis is a risk factor in the origin and evolution of numerous chronic systemic diseases, such as Diabetes mellitus; endocrine disorder characterized by hyperglycemia, hyperinsulinemia, and insulin resistance. The detrimental effects of periodontal infections on Diabetes are explained by the increase of systemic proinflammatory mediators, which would aggravate the state of insulin resistance, considering these patients with periodontal involvement as systemically compromised patients. Diabetes mellitus and Periodontitis share a complex evolution and between them a bidirectional relationship is established. The aim of this review is to provide a current view on molecular and cellular processes that link periodontal disease and chronic inflammation with diabetes mellitus (AU)

Relationship Between Glycemic Control and Coated Tongue in Type 2 Diabetes Mellitus Patients with Xerostomia

Abstract Objective: To examine the relationship between the level of glycemic control and coated tongue in type 2 diabetes mellitus patients with xerostomia. Material and Methods: This study was an analytical survey and involved 64 type 2 diabetes mellitus patients, aged between 17 to 65 years old with 34 males and 30 females. Diagnosis of diabetes mellitus was determined from the patient's medical records. The level of glycemic control was obtained from the patient's last blood sugar examination. Xerostomia was diagnosed with a questionnaire, while coated tongue diagnosis based on clinical features and the severity of coated tongue was assessed using the Kojima index Results: There was a significant relationship between the level of glycemic control and coated tongue (p=0.0026) in type 2 diabetes mellitus patients with xerostomia. Moreover, there was a significant relationship between the level of glycemic control and the severity of the coated tongue (p=0.001). Specifically, poor glycemic control was associated with a higher occurrence of the coated tongue as well as more severe tongue coating Conclusion: There was a significant relationship between the level of glycemic control in and coated tongue in type 2 diabetes mellitus patients with xerostomia. Therefore, diabetes mellitus patients should control their level of glycemic control to prevent the oral complication of the disease.
