BACKGROUND: Diabetic retinopathy (DR) is an important cause of decreased visual acuity, whose prevalence has increased between 1990 and 2020. In Chile the prevalence of diabetic retinopathy was estimated at 24.8%. AIM: To assess the prevalence of DR in a southern Chilean city. MATERIAL AND METHODS: From a database of diabetic patients attending primary health care centers at Puerto Montt, Chile, 196 patients with DR and 392 patients without DR, matched by age and presence of chronic complications, were chosen for this case-control study. RESULTS: The prevalence of DR in the database of diabetic patients was 33.3%. glycated hemoglobin, the frequency insulin use, systolic blood pressure, HDL cholesterol, microalbuminuria, and proteinuria were significantly worse in cases. A multivariate analysis showed that retinopathy is much more likely to occur when the variables insulin use, neuropathy, and microalbuminuria concur. CONCLUSIONS: DR was associated with worse metabolic parameters and the presence of neuropathy in this case control study.

Pouco se sabe sobre a atuação do psicólogo no Brasil junto a pessoas com Diabetes Mellitus. O objetivo desta pesquisa foi identificar os psicólogos brasileiros que trabalham com essa população e suas ações. Foram convidados a responder a um questionário online psicólogos que atuam ou atuaram junto a pessoas com diabetes. Participaram 79 psicólogos, principalmente da região Sudeste (59,5%). Todos declararam que haviam cursado pósgraduação. Na amostra, predominou o gênero feminino (89,9%), com idade entre 26 e 40 anos (46,8%). A maioria dos que atuam com diabetes declarou-se autônoma ou voluntária, e quase metade trabalhava menos do que 10 horas semanais. Entre aqueles que deixaram de trabalhar com diabetes, apenas uma minoria tinha vínculo empregatício. Além do trabalho com pessoas com diabetes, a maior parte declarou exercer outras atividades profissionais, como atendimentos clínicos em consultórios particulares, sugerindo que esta não é a atividade principal. Majoritariamente, os respondentes declararam não ter conhecimentos suficientes para o atendimento específico às pessoas com diabetes. Discute-se a qualidade da formação profissional dos psicólogos no Brasil, a necessidade de aprimoramento em relação à atuação com pessoas com diabetes e as condições de trabalho.(AU)

Little is known about the practice of psychologists in Brazil caring for people with Diabetes Mellitus. The aim of this research was to identify the Brazilian psychologists who work with this population and describe their actions. Psychologists who work or have worked with people diagnosed with diabetes were invited to answer an online questionnaire. The 79 participants lived mainly in the Southeast Region (59.5%). All of them declared to have a graduate degree, most were female (89.9%), aged 26 to 40 years (46.8%). Most of those working with diabetes declared to be autonomous or voluntary, and almost half had a workload of less than 10 hours a week. Among those who stopped working with diabetes, only a minority had a formal employment contract. In addition, most of them stated that they had other professional activities related to clinical care in private offices, suggesting that working with diabetes is not their main activity. Mostly, respondents stated that they did not have enough knowledge to care for people with diabetes. The quality of professional education of psychologists in Brazil, the need for specific improvement in labor relations and conditions were discussed.(AU)

OBJECTIVE@#To observe the hypoglycemic effect of electroacupuncture (EA) at "Tianshu" (ST 25) combined with metformin on rats with type 2 diabetes mellitus (T2DM) as well as its effect on expression of adenosine monophosphate activated protein kinase (AMPK) in liver and pancreas.@*METHODS@#Thirty-six male SD rats were randomly divided into a blank group (6 rats) and a model establishing group (30 rats). The rats in the model establishing group were fed with high-fat diet and treated with intraperitoneal injection of low-dose streptozotocin (STZ) to establish T2DM model. The rats with successful model establishment were randomly divided into a model group, a control group, a metformin group, an EA group and a combination group, 6 rats in each group. The rats in the EA group were treated with EA at "Tianshu" (ST 25), dense-disperse wave, 2 Hz/15 Hz in frequency and 2 mA in current intensity, 20 min each time. The rats in the metformin group were treated with intragastric administration of metformin (190 mg/kg) dissolved in 0.9% sodium chloride solution (2 mL/kg). The rats in the combination group were treated with EA at "Tianshu" (ST 25) and intragastric administration of metformin. The rats in the control group were treated with intragastric administration of 0.9% sodium chloride solution with the same dose. All the treatments were given once a day for 5 weeks. After the intervention, the body mass and random blood glucose were detected; the serum insulin level was detected by ELISA; the expression of AMPK and phosphorylated adenosine monophosphate activated protein kinase (p-AMPK) in liver and pancreas was detected by Western blot method; the expression of protein gene product 9.5 (PGP9.5) was detected by immunofluorescence.@*RESULTS@#①Compared with the blank group, the body mass in the model group was decreased (P<0.05); compared with the model group, the body mass in the EA group and the combination group was decreased (P<0.05); the body mass in the EA group and the combination group was lower than the metformin group (P<0.05). Compared with the blank group, the random blood glucose in the model group was increased (P<0.01); compared with the model group, the random blood glucose in the metformin group, the EA group and the combination group was decreased (P<0.01). The random blood glucose in the combination group was lower than the metformin group and the EA group (P<0.05). ②Compared with the blank group, the insulin level in the model group was decreased (P<0.05); compared with the model group, the insulin level in the metformin group, the EA group and the combination group was all increased (P<0.05). The insulin level in the combination group was higher than the metformin group and the EA group (P<0.05). ③Compared with the blank group, the protein expression of AMPK and p-AMPK in liver tissue was decreased (P<0.05), and the protein expression of AMPK and p-AMPK in pancreatic tissue was increased (P<0.05) in the model group. Compared with the model group, the protein expression of AMPK and p-AMPK in liver tissue in the metformin group, the EA group and the combination group was increased (P<0.05, P<0.01); the protein expression of AMPK in pancreatic tissue in the metformin group was increased (P<0.05); the protein expression of AMPK in pancreatic tissue in the EA group and the combination group was decreased (P<0.05); the protein expression of p-AMPK in pancreatic tissue in the metformin group, the EA group and the combination group was decreased (P<0.05). The protein expression of AMPK and p-AMPK in liver tissue in the combination group was higher than that in the metformin group and the EA group (P<0.05); the protein expression of AMPK in pancreatic tissue in the EA group and the combination group was less than that in the metformin group (P<0.05), and the expression of p-AMPK protein in pancreatic tissue in the combination group was less than that in the metformin group and the EA group (P<0.05). ④Compared with the blank group, the expression of PGP9.5 in pancreatic tissue in the model group was increased (P<0.01); compared with the model group, the expression of PGP9.5 in pancreatic tissue in the metformin group, the EA group and the combination group was decreased (P<0.05, P<0.01). The expression of PGP9.5 in pancreatic tissue in the EA group was lower than the metformin group and the combination group (P<0.05).@*CONCLUSION@#Electroacupuncture at "Tianshu" (ST 25) could promote the effect of metformin on activating AMPK in liver tissue of T2DM rats, improve the negative effect of metformin on AMPK in pancreatic tissue, and enhance the hypoglycemic effect of metformin. The mechanism may be related to the inhibition of pancreatic intrinsic nervous system.

BACKGROUND@#Progressive lipid loss of adipose tissue is a major feature of cancer-associated cachexia. In addition to systemic immune/inflammatory effects in response to tumor progression, tumor-secreted cachectic ligands also play essential roles in tumor-induced lipid loss. However, the mechanisms of tumor-adipose tissue interaction in lipid homeostasis are not fully understood.@*METHODS@#The yki -gut tumors were induced in fruit flies. Lipid metabolic assays were performed to investigate the lipolysis level of different types of insulin-like growth factor binding protein-3 (IGFBP-3) treated cells. Immunoblotting was used to display phenotypes of tumor cells and adipocytes. Quantitative polymerase chain reaction (qPCR) analysis was carried out to examine the gene expression levels such as Acc1 , Acly , and Fasn et al .@*RESULTS@#In this study, it was revealed that tumor-derived IGFBP-3 was an important ligand directly causing lipid loss in matured adipocytes. IGFBP-3, which is highly expressed in cachectic tumor cells, antagonized insulin/IGF-like signaling (IIS) and impaired the balance between lipolysis and lipogenesis in 3T3-L1 adipocytes. Conditioned medium from cachectic tumor cells, such as Capan-1 and C26 cells, contained excessive IGFBP-3 that potently induced lipolysis in adipocytes. Notably, neutralization of IGFBP-3 by neutralizing antibody in the conditioned medium of cachectic tumor cells significantly alleviated the lipolytic effect and restored lipid storage in adipocytes. Furthermore, cachectic tumor cells were resistant to IGFBP-3 inhibition of IIS, ensuring their escape from IGFBP-3-associated growth suppression. Finally, cachectic tumor-derived ImpL2, the IGFBP-3 homolog, also impaired lipid homeostasis of host cells in an established cancer-cachexia model in Drosophila . Most importantly, IGFBP-3 was highly expressed in cancer tissues in pancreatic and colorectal cancer patients, especially higher in the sera of cachectic cancer patients than non-cachexia cancer patients.@*CONCLUSION@#Our study demonstrates that tumor-derived IGFBP-3 plays a critical role in cachexia-associated lipid loss and could be a biomarker for diagnosis of cachexia in cancer patients.

OBJECTIVE@#To explore the clinical and genetic characteristics of a boy with isolated maternal uniparental disomy of chromosome 20 [UPD(20)mat].@*METHODS@#A child who was admitted to the Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology on April 8,2021. was selected as the study subject. Phenotypic and endocrinological findings of the child were retrospectively analyzed. Whole exome sequencing (WES) and methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) were carried out for detecting the UPD sequences and copy number variations. Both of his parents were verified by Sanger sequencing. Relevant literature was systematically reviewed.@*RESULTS@#The child, a 3-year-and-8-month-old boy born to a 41-year-old mother by Cesarean delivery at 36+2 gestational weeks due to oligohydramia, had a birth weight of 2 300 g and length of 46 cm. He was admitted to the NICU for feeding difficulties which had persisted despite of clinical management. At the age of 3.75, he had a height of 92.5 cm (< 3rd percentile; 25th ~ 50th percentile at 2.5 years) and a weight of 10.8 kg (< 3rd percentile; 50th percentile at 15 months). He had also presented with growth retardation, short stature, attention deficit and hyperactivity disorder (ADHD), mild mental retardation, and speech and language development disorders. He had simian creases in both hands but no additional dysmorphic signs, and his motor development was normal. Serum insulin, thyroid-stimulating hormone, and insulin growth factor binding protein 3 levels were within the normal ranges, though insulin growth factor-1 (IGF-1) was slightly decreased. Since that time he had continuously used atomoxetine hydrochloride capsules to control his ADHD. WES and MS-MLPA revealed the existence of UPD (20)mat.@*CONCLUSION@#The UPD(20)mat syndrome is characterized by feeding difficulties, growth retardation and short stature. The child in our case has been accompanied by ADHD and speech and language development disorders, which required long-term treatment. For women with advanced maternal age and suggestive phenotypes, genetic testing and counseling should be conducted.

OBJECTIVES@#Insulin signaling pathway plays an important role in metabolic associated fatty liver disease (MAFLD), however, the association between polymorphisms of genes related to insulin signaling pathway and MAFLD remains unclear. This study aims to investigate the association between insulin signaling pathway-related gene polymorphisms and gene-gene interactions with MAFLD susceptibility in obese children so as to provide scientific basis for further study of genetic mechanism.@*METHODS@#A total of 502 obese children with MAFLD who admitted to Hunan Provincial Children's Hospital from September 2019 to October 2021, were recruited as a case group, and 421 obese children with non-MAFLD admitted during the same period were recruited as a control group. Socio-demographic information, preterm birth history, eating habits, and exercise status of the subjects were collected by inquiry survey, and anthropometric information was collected by physical measurement. At the same time, 2 mL of venous blood was collected to extract DNA, and the polymorphism of insulin signaling pathway-related genes (5 representative candidate genes, 12 variants) was detected. Multivariate Logistic regression analysis was used to investigate the association between insulin signaling pathway-related gene polymorphisms and MAFLD in obese children.@*RESULTS@#After adjusting for confounder factors, INS rs3842748 was significantly associated with the risk of MAFLD in obese children in allele, heterozygous, and dominant models [OR and 95% CI 1.749 (1.053 to 2.905), 1.909 (1.115 to 3.267), 1.862 (1.098 to 3.157), all P<0.05]; INS rs3842752 was significantly associated with the risk of MAFLD in obese children in heterozygous and dominant models [OR and 95% CI 1.736 (1.028 to 2.932), 1.700 (1.015 to 2.846), all P<0.05]. NR1H3 rs3758674 was significantly correlated with the risk of MAFLD in obese children in allele model [OR and 95% CI 0.716 (0.514 to 0.997), P<0.05]. SREBP-1c rs2297508 was significantly associated with the risk of MAFLD in obese children in allele and dominant models [OR and 95% CI 0.772 (0.602 to 0.991) and 0.743 (0.557 to 0.991), all P<0.05]. SREBP-1c rs8066560 was significantly associated with the risk of MAFLD in obese children in allele, heterozygous, and dominant models [OR and 95% CI 0.759 (0.589 to 0.980), 0.733 (0.541 to 0.992), 0.727 (0.543 to 0.974), all P<0.05]. NR1H3 rs3758674 mutant C and SREBP-1c rs2297508 mutant G had interaction in the development of MAFLD in obese children [OR and 95% CI 0.407 (0.173 to 0.954), P<0.05].@*CONCLUSIONS@#The INS, NR1H3, and SREBP-1c gene polymorphisms in the insulin signaling pathway are associated with the susceptibility of MAFLD in obese children, but the functions and mechanisms of these genes need to be further studied.

La ataxia de Friedreich, de herencia autosómica recesiva causada por una expansión repetida de trinucleótidos se asocia, entre otras complicaciones sistémicas, con diabetes mellitus. La aparición de torpeza motriz, con dificultad en la carrera y el salto en un varón de 6 años motivaron el estudio genético para ataxia de Friedrich y permitieron confirmar el diagnóstico. Tres años más tarde, se diagnosticó diabetes mellitus y se inició el tratamiento con insulina. Durante el seguimiento, presentó un importante deterioro neurológico, con necesidad de usar silla de ruedas, lo que dificultó un adecuado control metabólico. Se presenta el manejo y la evolución de un paciente con ataxia de Friedreich y diabetes mellitus

Friedreich's ataxia is an autosomal recessive disease caused by trinucleotide repeat expansion, presenting among other systemic complications, diabetes mellitus. The appearance of motor clumsiness, with running and jumping difficulties in a 6-year-old boy prompted the genetic study of Friedreich's ataxia, confirming his diagnosis. After diagnosis,it was evaluated by Pediatric Cardiology, detecting the presence of non-obstructive hypertrophic cardiomyopathy, and by Pediatric Endocrinology, due to overweight. At 9 years of age, he was diagnosed with diabetes mellitus, a regimen of insulin treatment was initiated. During follow-up, he presented significant neurological deterioration, reaching the use of a wheelchair,which hinders adequate metabolic control. This is a report of a pediatric patient with Friedrich ataxia and diabetes mellitus.

The objective was to evaluate the antioxidant capacity, glucose and insulin concentration and reproductive performance of ewes supplemented with orange residue prior to insemination. Fifty-five multiparous ewes were divided into two corrals, and 15 unbred ewes were kept individually to measure feed consumption. Two integral diets were administered; T0: control treatment and T1: with 20% of dry matter of orange residue. Ten days after the start of supplementation, the ewes were synchronized. Supplementation was finalized prior to artificial insemination, then, a blood sample was taken to measure the antioxidant capacity and glucose and insulin concentration. An analysis of variance was made to evaluate the effect of treatment on the antioxidant capacity, glucose and insulin; and to analyze the response to estrus, percentage of gestation and prolificity a ji squared test was performed. Of 9 antioxidant compounds found in the orange residue, hesperidin (7.44%), chlorogenic acid (0.50%) and protocatechuic acid had the highest concentration. Feed intake, estrus response, percentage of gestation, antioxidant capacity, and glucose and insulin concentration were not affected by the treatment. It is concluded that inclusion of 20% of orange residue in the diet prior to insemination in ewes is possible.(AU)

O objetivo deste estudo foi avaliar a capacidade antioxidante, a concentração de glicose e insulina e o comportamento reprodutivo de ovelhas suplementadas com resíduo de laranja antes da inseminação. Cinquenta e cinco ovelhas multíparas foram divididas em dois currais e 15 ovelhas sem raça foram mantidas individualmente para se medir o consumo de ração. Duas dietas integrais foram administradas; T0: tratamento controle e T1: dieta com 20% de resíduo de laranja seco. Dias após o início da suplementação, as ovelhas foram sincronizadas. A suplementação foi finalizada antes da inseminação artificial e, em seguida, foi coletada uma amostra de sangue para medir a capacidade antioxidante e a concentração de glicose e insulina. Uma análise de variância foi feita para avaliar o efeito do tratamento sobre a capacidade antioxidante, a glicose e a insulina, e um teste do ji quadrado foi realizado para analisar a resposta ao estro, a porcentagem de gestação e de prolificidade. Dos nove compostos antioxidantes encontrados no resíduo laranja, a hesperidina (7,44%), o ácido clorogênico (0,50%) e o ácido protocatecuico foram os de maior concentração. O consumo alimentar, a resposta ao estro, a porcentagem de gestação, a capacidade antioxidante, a concentração de glicose e a insulina não foram afetados pelo tratamento. Conclui-se que é possível a inclusão de 20% de resíduos de laranja na dieta antes da inseminação em ovelhas.(AU)

ABSTRACT Objective: The aim of this study was to evaluate the frequency of hypoglycemia and the treatment satisfaction in patients with type 1 diabetes (T1D) using insulin analogues. Subjects and methods: This observational retrospective study included 516 adult patients with T1D from 38 cities in Southern Brazil. Demographics and clinical data were collected using a self-report questionnaire. Hypoglycemia was defined as an event based on either symptoms or self-monitored blood glucose < 70 mg/dL. Treatment satisfaction was evaluated using the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) and with a specific question with scores ranging from 0-10. Common mental disorders were assessed using the General Health Questionnaire (GHQ-12). Results: Overall, the mean age was 38 ± 14 years and 52% of the participants were women. The median diabetes duration was 18 years. The scores for insulin analogue treatment satisfaction were higher than those for previous treatments. DTSQ scores had a median value of 32 (interquartile range 29-35) and remained unchanged over time. The percentage of patients with hypoglycemia (including severe and nocturnal) was comparable across groups divided according to duration of use of insulin analogues. Most patients (n=395, 77%) screened positive for common mental disorders. Conclusions: Patient satisfaction with insulin analogue treatment was high and remained unchanged with time. Episodes of hypoglycemia also remained unchanged over time among patients using insulin analogues.

Los avances en el campo de la fibrosis quística han aumentado la esperanza de vida de estos pacientes, por lo que cada vez es más prevalente la Diabetes Relacionada con la Fibrosis Quística (DRFQ) y sus complicaciones. La DRFQ se asocia a mayor morbimortalidad, deterioro de la función pulmonar y del estado nutricional. Por lo mismo, el manejo óptimo de esta patología depende de un diagnóstico precoz, tratamiento individualizado y vigilancia de las complicaciones diabéticas. El screening de DRFQ debe realizarse anualmente a partir de los 10 años, mediante una Prueba de Tolerancia a la Glucosa Oral (PTGO), lo cual permite el diagnóstico. El manejo de esta patología tiene por objetivo estabilizar y mejorar la función pulmonar y el estado nutricional y metabólico de los pacientes. Actualmente, la insulina es el tratamiento farmacológico de elección para controlar la hiperglicemia y el esquema de uso debe ser individualizado para cada persona. En caso de enfermedades agudas pueden existir mayores requerimientos de insulina. Además, se deben tener consideraciones especiales en cuanto a la dieta y la insuficiencia pancreática exocrina que presentan estos pacientes. Para la vigilancia de complicaciones microvasculares se debe realizar una monitorización anual a partir de los 5 años desde el diagnóstico de DRFQ. Debido a la complejidad de estos pacientes, para alcanzar el mejor cuidado posible se necesita un enfoque multidisciplinario con distintos profesionales de la salud coordinados, incluyendo en la toma de decisiones al paciente y su familia.

Advances made in the field of cystic fibrosis have increased the life expectancy of these patients, which is why Cystic Fibrosis-Related Diabetes (CFRD) and its complications are becoming more and more prevalent. CFRD is associated with increased morbidity and mortality, lower lung function and inadequate weight maintenance. Therefore, the optimal management of this pathology depends on an early diagnosis, individualized treatment and monitoring of diabetic complications. For CFRD, routine screening with an Oral Glucose Tolerance Test (OGTT) should be carried out yearly from the age of 10, which allows to diagnose it. The treatment goals in CFRD are to stabilize and improve lung function and obtain adequate weight gain. Currently, insulin is the pharmacological treatment of choice to control hyperglycemia and the insulin regimen must be personalized for each person. In acute illnesses, there may be higher insulin requirements. In addition, special considerations must be taken regarding diet and exocrine pancreatic insufficiency that these patients present. For the surveillance of microvascular complications, annual monitoring should be carried out 5 years after the diagnosis of CFRD. Due to the complexity of these patients, in order to achieve the best possible care, a multidisciplinary approach is needed with different coordinated health professionals, including the patients and their family in the decision-making process.

ABSTRACT Objectives: The purpose of this study was to investigate the heterogeneity of the association between glycemic variability and oxidative stress markers in T1DM patients under daily life insulin treatment. Subjects and methods: We studied, in a cross-sectional analysis, 76 T1DM patients without clinical chronic diabetes complications and 22 healthy individuals. Were evaluated the short-term glycemic variability (STGV), long-term glycemic variability (LTGV), oxidative stress markers [8-isoprostaglandin-F2α (Ur-8-iso-PGF2α), nitric oxide (NO), thiobarbituric acid reactive substances (TBARS) and erythrocytes reduced/oxidized glutathione (GSH/GSSG)] and biochemical dosages (glycaemia, HbA1c, lipidogram, albuminuria). Results: Plasmatic NO was positively associated with LTGV (last year average of HbA1c) (8.7 ± 1.6% or 71 ± 18 mmol) (rS: 0.278; p: 0.042). Plasmatic TBARS, erythrocytes GSH/GSSH and Ur-8-iso-PGF-2α didn't show correlation with glycemic variability. GSH/GSSG was inversely correlated with LDL-cholesterol (rS: - 0.417; p: 0.047) and triglycerides (rS: −0.521; p: 0.013). Albuminuria was positive correlated with age (rS: 0.340; p: 0.002), plasmatic NO (rS: 0.267; p 0.049) and TBARS (rS: 0.327; p: 0.015). Conclusion: In daily life insulin treatment, young T1DM patients have higher plasmatic NO than healthy subjects. However, the correlation between glycemic variability and oxidative stress markers is heterogeneous. Lipid profile and albuminuria are associated with different oxidative stress markers. These data collaborate to explain the controversial results in this issue.

The purpose of the present overview of meta-analysis is to summarize and critically assess the effect of isoflavones and genistein on glucose metabolism among the peri- and post-menopausal women. Two independent authors searched the databases of MEDLINE, Scopus and Cochrane Library for meta-analysis. Three databases were searched from inception to January 2018. Methodological quality of each meta-analysis of randomized controlled trials was evaluated using the AMSTAR (a measurement tool used to assess systematic reviews). Four meta-analyses were included to the current overview. Fasting insulin levels and homeostatic model assessment of insulin resistance (HOMA-IR) values were significantly lower in peri-menopausal and postmenopausal. Two meta-analyses showed that treatment with isoflavones could not alter fasting blood glucose. However, one meta-analysis depicted that isoflavones significantly improved blood glucose levels in non-Asian postmenopausal women. Treatment with genistein could have significant beneficial effects on fasting insulin, blood glucose and HOMA-IR in comparison to the control group. Regardless of the population, the treatment with genistein is effective in improving fasting insulin, HOMA-IR and glucose levels. Nevertheless, the high heterogeneity among studies and poor methodology of reviews made it difficult to draw a definite conclusion on the positive impacts of soy on glucose metabolism.

The thiazolidinediones (TZDs) class comprises drugs with hypoglycemic effects, reducing insulin resistance in peripheral tissues. Our group has demonstrated in preliminary in vivo studies that a new TZD, GQ-11, improves insulin resistance as well as modulates cytokines involved in inflammatory process, suggesting an interesting approach for therapeutic alternatives in tissue repair, especially in metabolic decompensation cases, as insulin resistance and ischemia-reperfusion. In this context, the aim of this study was to investigate GQ-11 effects in tissue repair in three different models: insulin resistance in db/db mice, reconstructed human epidermis (RHE) in glycated collagen matrix and ischemia/reperfusion induced by aorta clamping in Wistar rats. In insulin resistance context, GQ-11 treatment upregulated the expression of anti-inflammatory mediators, such as IL-10, TGF-ß and Arg-1, downregulated the expression of pro-inflammatory cytokines both in db/db mice wounds and in macrophage, besides increasing re-epithelization and collagen deposition. In addition, the treatment also induced keratinocytes proliferation and fibroblasts differentiation in RHE. In ischemia-reperfusion model, the same anti-inflammatory effect was observed along with anti-oxidant properties through regulation of enzymes, such as catalase and GPx, as well as by decreasing TBARS formation. Animals imaging by positron emission tomography (PET) indicated significant less 18F-FDG uptake in animal treated with GQ-11 compared to controls, suggesting decrease of the inflammation process related to reperfusion after aorta clamping. Concluding, the dual PPARα/γ agonist GQ-11 has an important antiinflammatory effect, suggesting a new approach to tissue repair management in diabetes and in prevention of ischemia-reperfusion syndrome post-surgery

As tiazolidinadionas (TZDs) compreendem uma classe de fármacos hipoglicemiantes que reduzem a resistência à insulina pelos tecidos periféricos. Dados preliminares in vivo obtidos em nosso grupo de pesquisa mostraram que um dos novos derivados tiazolidínicos, GQ-11, além de aumentar a resposta à insulina, pode inibir citocinas pró-inflamatórias, o que a torna uma alternativa terapêutica promissora no reparo tecidual, em especial, nos casos de descompensação metabólica como ocorre na resistência à insulina e na isquemia/reperfusão. Nesse contexto, o objetivo deste trabalho foi investigar os efeitos da GQ-11 nas etapas do processo de reparo tecidual em três modelos: resistência à insulina utilizando camundongos db/db, epiderme humana reconstruída em matriz de colágeno glicado e isquemia/reperfusão induzida por clampeamento da aorta em ratos Wistar. No contexto de resistência à insulina, o tratamento com GQ-11 induziu a expressão de mediadores anti-inflamatórios como IL-10, TGF-ß e Arg-1 e diminuiu a expressão de citocinas pró-inflamatórias em lesões de camundongos db/db e em macrófagos, além de aumentar a capacidade de re-epitelização e a deposição de colágeno. Além disso, o tratamento também induziu a proliferação de queratinócitos e a diferenciação de fibroblastos em epiderme humana reconstruída em matriz de colágeno glicado. No modelo de isquemia-reperfusão, o mesmo efeito anti-inflamatório da GQ-11 foi observado ao lado de efeitos anti-oxidantes através da regulação de enzimas como catalase, GPx e diminuição de TBARS. O imageamento dos animais através de tomografia por emissão de pósitrons (PET) demonstrou menor captação de 18F-FDG (18F-fluordesoxiglicose), indicando diminuição do processo inflamatório decorrente da reperfusão pós clampeamento aórtico. Dessa forma, conclui-se que GQ-11, um agonista dual de PPARα/γ, tem efeito anti-inflamatório importante, podendo ser um candidato à fármaco com possível aplicação no reparo tecidual no diabetes e na prevenção da síndrome de isquemia-reperfusão desenvolvida após procedimentos cirúrgicos

ntroducción: La diabetes mellitus tipo 1 (DM1) es la enfermedad crónica más frecuente en la edad pediátrica. La educación del niño con DM1 es fundamental para un adecuado control de la enfermedad. Las lipohipertrofias son una de las complicaciones más frecuentes que se producen por el tratamiento con insulina. Estas son consideradas problemas de colaboración y, por lo tanto, es labor de la enfermera controlar su aparición e intervenir para minimizar sus consecuencias. Objetivo: Determinar las características de las lipohipertrofias en niños diagnosticados con diabetes mellitus tipo 1. Métodos: Estudio descriptivo transversal mediante muestreo por conveniencia. Se evaluó la presencia, localización y tamaño de las lipohipertrofias y la relación de la persona que administra la insulina con el régimen de tratamiento. Se estudiaron pacientes de edades comprendidas entre 2 y 18 años que tuviesen, al menos, 3 meses de tratamiento insulínico. Se calculó el tamaño de la muestra mediante estimación de la proporción. Resultados: La prevalencia de lipohipertrofias fue del 44,5 por ciento. Sin embargo, entre los niños estudiados que se encontraban en tratamiento con múltiples dosis de insulina, el porcentaje se elevó a 53,8 por ciento. Los análogos de acción rápida eran inyectados principalmente en abdomen y brazo, los de acción lenta en glúteo y muslo. Los lugares con más lipohipertrofias eran muslos (superando el 50 por ciento), seguido de brazos y abdomen. Conclusiones: Se detectaron diferencias significativas en la aparición de lipohipertrofias entre los niños que portan bomba de insulina y los que utilizan un régimen de múltiples dosis de insulina. Por lo tanto, se podría recomendar la utilización de bomba de insulina o de catéteres de infusión subcutánea (i-Port ®) para la disminución de estas(AU)

Introduction: Type 1 diabetes mellitus (T1DM) is the most common chronic disease in the pediatric age. In order to obtain a positive control of this illness, the T1DM child education is basic. Lipohypertrophies are one of the most frequent difficulties that appear as a consequence of the insulin treatment. When this happen, is nurse's responsibility to monitor the appearance of lipohypertrophies and to try to reduce their consequences. Objectives: Establish the prevalence of lipohypertrophy in children with T1DM performed at the Pediatric Endocrinology Unit of the Hospital Universitario La Paz. Methods: To analyze lipohypertrophy it has been performed a descriptive study. The method used for the sampling was for convenience. Appearance, location and size of lipohypertrophies were evaluated. This has been related with person who administers the insulin and the treatment regimen. Results: Lipohypertrophy prevalence in the sample represented a 44.5 percent, however, between patients which were in a treatment with multiple daily injections this was 53.8 percent. Quick action analogues were mainly injected in abdomen and arms, slow action analogues were aministered in buttocks and leg. Legs were the part of the body with the most lipohypertrophies concentration (exceeded 50 percent), follow by arms and abdomen. Conclusions: Meaningful differences are shown in the appearance of lipohypertrophies between children in treatment with continuous subcutaneous insulin infusion and those that use a multiple daily injections treatment. Therefore, we concluded considering the possibility to recommend the use of continuous subcutaneous insulin infusion or indwelling catheters (i-Port ®) in order to decrease lipohypertrophies(AU)

Resumo As insulinas análogas são alvo de controvérsias quanto à sua superioridade terapêutica em relação às humanas. Talvez, em parte, devido a isso, são objetos frequentes de ações judicias. A judicialização da saúde tem sido muito estudada, mas pouco se sabe sobre os motivos que levam as pessoas a recorrerem ao Judiciário para obter acesso a medicamentos no SUS. Sendo assim, o presente estudo tem por objetivo analisar os motivos que levaram as pessoas a recorrerem ao Judiciário para obter o acesso às insulinas análogas no estado da Bahia, tratando-se de um estudo de caso apoiado em fonte documental. Foram analisadas, entre 2010 e 2013, 149 ações judiciais que solicitaram o fornecimento de análogas pela secretaria estadual da saúde. Os motivos do recurso à Justiça, citados nos autos, podem ser classificados em: hipossuficiência financeira do usuário, necessidade de insulina análoga, dever e obrigação do Estado em fornecê-las e dificuldades burocráticas. Majoritariamente, as pessoas recorreram ao Judiciário, porque os médicos que as acompanham, divergindo das políticas oficiais, acreditam que as insulinas análogas são melhores do que às humanas e o sistema público de saúde não as dispensa, não dispondo elas de condições financeiras que lhes permitam adquiri-las com recursos próprios.

Abstract Insulin analogues have been the object of controversy concerning their therapeutic superiority to human insulin. Perhaps, in part, because of this, insulin analogues are frequently the subject of lawsuits. The judicialization of health has been well studied, but little is known about the reasons that lead people to go to the courts to obtain access to medicines on SUS (the Brazilian National Health System). Therefore, this study aims to analyze the reasons that led people to appeal to the courts to obtain access to insulins analogues in the state of Bahia. This is a case study based on documentary sources. Between 2010 and 2013, 149 lawsuits requiring insulin analogues from the state health authority were filed in the courts. The main reasons for the appeal to the courts, cited in the cases, can be grouped into four categories: the users’ lack of finances, an essential need for insulin analogue, the duty and obligation of the state to provide them and bureaucratic difficulties. People turned to the courts, mostly, because doctors who accompany their patients have shifted from the official policy, believing that insulin analogues are better than human insulins. They also recognize that the public health system does not distribute them nor does it give doctors the wherewithal to purchase them with their own resources.
