Macrophages, IL-10, and nitric oxide increase, induced by hyperglycemic conditions, impact the development of murine melanoma B16F10-Nex2.

Epidemiological studies show a strong correlation between diabetes and the increased risk of developing different cancers, including melanoma. In the present study, we investigated the impact of a streptozotocin (STZ)-induced hyperglycemic environment on B16F10-Nex2 murine melanoma development. Hyperglycemic male C57Bl/6 mice showed increased subcutaneous tumor development, partially inhibited by metformin. Tumors showed increased infiltrating macrophages, and augmented IL-10 and nitric oxide (NO) concentrations. In vivo neutralization of IL-10, NO synthase inhibition, and depletion of macrophages reduced tumor development. STZ-treated TLR4 KO animals showed delayed tumor development; the transfer of hyperglycemic C57Bl/6 macrophages to TLR4 KO reversed this effect. Increased concentrations of IL-10 present in tumor homogenates of hyperglycemic mice induced a higher number of pre-angiogenic structures in vitro, and B16F10-Nex2 cells incubated with different glucose concentrations in vitro produced increased levels of IL-10. In summary, our findings show that a hyperglycemic environment stimulates murine melanoma B16F10-Nex2 primary tumor growth, and this effect is dependent on tumor cell stimulation, increased numbers of macrophages, and augmented IL-10 and NO concentrations. These findings show the involvement of tumor cells and other components of the tumor microenvironment in the development of subcutaneous melanoma under hyperglycemic conditions, defining novel targets for melanoma control in diabetic patients.

Advanced glycation end products consumption and the decline of functional capacity in patients with Parkinson's disease: Cross-sectional study.

INTRODUCTION: Advanced Glycation End-Products (AGEs) are a diverse group of highly reactive molecules that play a vital role in the development of neurodegenerative disorders, such as Parkinson's Disease (PD), leading to a decline in functional and cognitive capacity. The objective of this study was to assess the intake and quantification of AGEs in individuals with PD and to correlate them with their functional and cognitive abilities. METHODS: This was a cross-sectional study involving 20 PD patients and 20 non-PD individuals as the Control group (C). The autofluorescence reader was used to evaluate skin AGEs, while food recall was used to quantify AGEs consumed for three different days. The Montreal Cognitive Assessment, Short Physical Performance Battery, and handgrip tests were used. PD patients demonstrated greater impairment in functional capacity compared to the control group. RESULTS: Dominant Handgrip (p = 0.02) and motor performance, in the sit and stand test (p = 0.01) and Short Physical Performance Battery (SPPB) (p = 0.01) were inferior in PD patients than the control group. Although PD patients tended to consume less AGEs than the control group, AGE intake was negatively correlated with handgrip strength in individuals with PD (r = -0.59; p < 0.05). CONCLUSION: PD patients had lower strength and functional capacity, suggesting that the effects of AGEs might be exacerbated during chronic diseases like Parkinson's.

Genipa americana L.: A New Phytochemical for White Hair Coloring.

This work describes a new hair dyeing methodology using a chemical reaction between geniposide, an iridoid glycoside extracted from the fruit of Genipa americana (geniposide extract, GE) and the amine group of hair keratin. The influence of reaction conditions (pH, temperature, and extract concentration) on the staining of hair fibers, color development, fiber morphology, and mechanical hair properties of black and white human hair samples, was evaluated before and after GE dyeing treatment. Eye contact safety of GE was also studied using HET-CAM. The treatment of white hair fibers using GE at 20 mg mL-1 , temperature of 80 °C and pH 5.5 presented the greatest color change (ΔE=54.0). The higher pH influence was observed at pH 10.0 on white hair tresses (ΔE=6.8), using an GE concentration of 20 mg mL-1 and room temperature (25 °C). Treated samples showed marked changes on mechanical and morphological properties. The HET-CAM did not show any change, thus demonstrating that using GE is safe. In conclusion, the temperature and concentration of the extract were the variables that mostly influenced the color and hair damage. A new approach for hair dyeing was established where iridoids may potentially be useful as a natural hair dyeing.

The Influence of Whey Protein on Muscle Strength, Glycemic Control and Functional Tasks in Older Adults with Type 2 Diabetes Mellitus in a Resistance Exercise Program: Randomized and Triple Blind Clinical Trial.

OBJECTIVES: To evaluate the effect of whey protein (WP) supplementation associated with resistance training (RT) on glycemic control, functional tasks, muscle strength, and body composition in older adults living with type 2 diabetes mellitus (T2DM). Secondly, to evaluate the safety of the protocol for renal function. METHODS: The population comprised twenty-six older men living with T2DM (68.5 ± 11.5 years old). The participants were randomly assigned to the Protein Group (PG) and the Control Group (CG). The handgrip test and evolution of exercise loads, according to the Omni Resistance Exercise Scale, evaluated muscle strength. Functional tasks were assessed by force platform in three different protocols: Sit-to-Stand, Step/Quick Turn, and Step Up/Over. Body composition was evaluated by bioimpedance and glycemic control and renal function were assessed by biochemical analyses. Both groups performed RT for 12 weeks, twice a week, prioritizing large muscle groups. Protein supplementation was 20 g of whey protein isolate and the CG was supplemented with an isocaloric drink, containing 20 g of maltodextrin. RESULTS: There was a significant difference in muscle strength, according to the evolution of the exercise loads, but it was not confirmed in the handgrip test. However, there was no significant difference between the groups, regarding performance in functional tasks, glycemic control, or body composition. Renal function showed no alteration. CONCLUSION: The intake of 20 g of WP in older male adults living with T2DM did not increase the effect of RT on muscle strength, functional tasks, and glycemic control. The intervention was proven safe regarding renal function.

Introduction: Assessing sociodemographic and socioeconomic factors related to Unified Health System's users is essential to plan and evaluate the actions by the health services sought by them.Aim: Describing the demographic and socioeconomic features of adult users, and their search for having their orthopedic and neurological-physical rehabilitation demands fulfilled by a Specialized Center in Orthopedic and Neurological Rehabilitation in Mato Grosso State.Methodology: Observational descriptive study based on medical records collected between February and March 2021, provided by the welcoming sector of a Specialized Center in Rehabilitation in Mato Grosso State. Demographic and socioeconomic records of adult users belonging to both sexes were analyzed. Person's chi-square test was adopted to associate the variables based on the orthopedic and neurological rehabilitation axes.Results: In total, 94% of the 196 analyzed medical records regard patients from Cuiabá, in the mean age group 50.3 years; 52.55% of them belonged to the female sex. The search for orthopedic rehabilitation reached 69% and that for neurological rehabilitation recorded 31%. There were significant statistical differences between frequencies on the two assessed physical rehabilitation axes based on variables such as age (p=0.0005), schooling (p=0.0031), main labor activity (p=0.0045), concomitant diseases (p=0.0016), treatment provided in another health establishment (p=0.0041) and reason for seeking rehabilitation (p<0.0001). Conclusions: Results have shown that neurological cases are linked to older age, low schooling and low rate of paid work in comparison to orthopedic cases. These results have suggested that health and rehabilitation needs depend on cases' particularities; moreover, they can subsidize the process to make public policies to reinforce services'organization, as well as inter-sectoral articulation among health, education and labor market, effective (AU).

INTRODUÇÃO: A obesidade é uma doença crônica e de causa multifatorial caracterizada pelo acúmulo excessivo de gordura no corpo. A cirurgia bariátrica é um dos procedimentos indicados para o tratamento da obesidade. OBJETIVO: Este estudo teve como objetivo analisar a satisfação física de mulheres submetidas à cirurgia bariátrica, avaliando a incidência de alterações psicológicas pós-operatórias, comportamentos alimentares, escores de autoestima e compulsão alimentar. MÉTODOS: Este projeto foi aprovado pelo Comitê de Ética da Universidade São Judas Tadeu (CAAE 46628521.5.0000.0089). Trata-se de um estudo de caráter quantitativo com delineamento transversal que foi realizado em um grupo de 39 indivíduos do sexo feminino, com idade entre 27 e 56 anos, que se submeteram à cirurgia bariátrica do tipo Bypass Gástrico em Y de Roux há pelo menos 2 anos. Foi utilizado um formulário (Google Forms - http://gg.gg/pesquisacirurgiabariatrica) para a coleta dos dados. RESULTADOS: A análise dos dados evidenciou que as participantes apresentam sobrepeso e insatisfação corporal, mas manifestam autoestima satisfatória. A maioria das participantes afirma experimentar sentimentos positivos ou negativos quando comem, além de não fazer acompanhamento psicológico. CONCLUSÃO: Nota-se a importância do acompanhamento multidisciplinar antes, durante e depois da cirurgia bariátrica para que os resultados sejam duradouros. A terapia cognitivo-comportamental pode ser extremamente eficaz nesse processo, pois atua na modificação de pensamentos e comportamentos disfuncionais diante das necessidades individuais.

INTRODUCTION: Obesity is a chronic, multifactorial disease characterized by the excessive accumulation of fat in the body. Bariatric surgery is one of the procedures indicated for the treatment of obesity. OBJECTIVE: This study aimed to analyze the physical satisfaction of women undergoing bariatric surgery, assessing the incidence of postoperative psychological changes, eating behaviors, self-esteem scores, and binge eating. METHODS: This project was approved by the Ethics Committee of São Judas Tadeu University (CAAE 46628521.5.0000.0089). This is a quantitative cross-sectional study that was carried out on a group of 39 females aged between 27 and 56 who had undergone Roux-en-Y gastric bypass surgery at least two years previously. A form (Google Forms - http://gg.gg/pesquisacirurgiabariatrica) was used to collect the data. RESULTS: Analysis of the data showed that the participants were overweight and had body dissatisfaction but expressed satisfactory self-esteem. Most of the participants said that they experience positive or negative feelings when they eat, and that they do not receive psychological counseling. CONCLUSION: It is important to have multidisciplinary support before, during, and after bariatric surgery so that the results are long-lasting. Cognitive-behavioral therapy can be extremely effective in this process, as it works to modify dysfunctional thoughts and behaviors in the face of individual needs.

Primates facing climate crisis in a tropical forest hotspot will lose climatic suitable geographical range.

Global climate changes affect biodiversity and cause species distribution shifts, contractions, and expansions. Climate change and disease are emerging threats to primates, and approximately one-quarter of primates' ranges have temperatures over historical ones. How will climate changes influence Atlantic Forest primate ranges? We used habitat suitability models and measured potential changes in area and distributions shifts. Climate change expected in 2100 may change the distribution area of Atlantic Forest primates. Fourteen species (74%) are predicted to lose more than 50% of their distribution, and nine species (47%) are predicted to lose more than 75% of their distribution. The balance was negative, indicating a potential future loss, and the strength of the reduction in the distribution is related to the severity of climate change (SSP scenarios). Directional shifts were detected to the south. The projected mean centroid latitudinal shift is ~ 51 km to the south for 2100 SSP5-8.5 scenario. The possibility of dispersal will depend on suitable routes and landscape configuration. Greenhouse gas emissions should be urgently reduced. Our results also emphasize that no more forest loss is acceptable in Atlantic Forest, and restoration, canopy bridges, friendly agroecosystems, and monitoring of infrastructure projects are urgent to enable dealing with climate change.

Quality of life and socio-demographic factors associated with nutritional risk in Brazilian community-dwelling individuals aged 80 and over: cluster analysis and ensemble methods.

Introduction: The aim of the present study was to use cluster analysis and ensemble methods to evaluate the association between quality of life, socio-demographic factors to predict nutritional risk in community-dwelling Brazilians aged 80 and over. Methods: This cross-sectional study included 104 individuals, both sexes, from different community locations. Firstly, the participants answered the sociodemographic questionnaire, and were sampled for anthropometric data. Subsequently, the Mini-Mental State Examination (MMSE) was applied, and Mini Nutritional Assessment Questionnaire (MAN) was used to evaluate their nutritional status. Finally, quality of life (QoL) was assessed by a brief version of World Health Organizations' Quality of Life (WHOQOL-BREF) questionnaire and its older adults' version (WHOQOL-OLD). Results: The K-means algorithm was used to identify clusters of individuals regarding quality-of-life characteristics. In addition, Random Forest (RF) and eXtreme Gradient Boosting (XGBoost) algorithms were used to predict nutritional risk. Four major clusters were derived. Although there was a higher proportion of individuals aged 80 and over with nutritional risk in cluster 2 and a lower proportion in cluster 3, there was no statistically significant association. Cluster 1 showed the highest scores for psychological, social, and environmental domains, while cluster 4 exhibited the worst scores for the social and environmental domains of WHOQOL-BREF and for autonomy, past, present, and future activities, and intimacy of WHOQOL-OLD. Conclusion: Handgrip, household income, and MMSE were the most important predictors of nutritional. On the other hand, sex, self-reported health, and number of teeth showed the lowest levels of influence in the construction of models to evaluate nutritional risk. Taken together, there was no association between clusters based on quality-of-life domains and nutritional risk, however, predictive models can be used as a complementary tool to evaluate nutritional risk in individuals aged 80 and over.

A Single Session of Virtual Reality Improved Tiredness, Shortness of Breath, Anxiety, Depression and Well-Being in Hospitalized Individuals with COVID-19: A Randomized Clinical Trial.

BACKGROUND: In 2020, the world was surprised by the spread and mass contamination of the new Coronavirus (COVID-19). COVID-19 produces symptoms ranging from a common cold to severe symptoms that can lead to death. Several strategies have been implemented to improve the well-being of patients during their hospitalization, and virtual reality (VR) has been used. However, whether patients hospitalized for COVID-19 can benefit from this intervention remains unclear. Therefore, this study aimed to investigate whether VR contributes to the control of pain symptoms, the sensation of dyspnea, perception of well-being, anxiety, and depression in patients hospitalized with COVID-19. METHODS: A randomized, double-blind clinical trial was designed. Patients underwent a single session of VR and usual care. The experimental group (n = 22) received VR content to promote relaxation, distraction, and stress relief, whereas the control group (n = 22) received non-specific VR content. RESULTS: The experimental group reported a significant decrease in tiredness, shortness of breath, anxiety, and an increase in the feeling of well-being, whereas the control group showed improvement only in the tiredness and anxiety. CONCLUSIONS: VR is a resource that may improve the symptoms of tiredness, shortness of breath, anxiety, and depression in patients hospitalized with COVID-19. Future studies should investigate the effect of multiple VR sessions on individuals with COVID-19.

RetINal Toxicity And HydroxyChloroquine Therapy (INTACT): protocol for a prospective population-based cohort study.

PURPOSE: Hydroxychloroquine (HCQ) is an important medication for patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and other rheumatic diseases. Although it is well-tolerated and cost-effective, the risk of HCQ retinal toxicity is of increasing concern. The aim of this study is to re-examine the HCQ retinal toxicity incidence rate, risk factors and clinical course after discontinuation. METHODS: We designed a prospective population-based cohort study in adult patients with SLE or RA, currently receiving HCQ for five or more years, who are residents of British Columbia (BC), Canada. Based on administrative data, we identified 5508 eligible participants (1346 SLE and 4162 RA). They will participate in annual or biannual retinal screening over 5 years in alignment with the recently revised American Academy of Ophthalmology guidelines. To standardise procedures for retinal screening, imaging, diagnostic criteria, severity staging and data transfer, a consensus meeting was convened in December 2019 with participation of BC retinal specialists and the research team. Agreement was attained on: use of spectral domain-optical coherence tomography as the primary objective screening modality; classification of images into categories of normal, equivocal or abnormal; and transferring the equivocal and abnormal images plus corresponding subjective test results via cloud-based server from each clinic to a reading centre. Confirmation of HCQ retinal toxicity diagnoses and severity staging will be performed by three independent and masked reviewers. The incidence of HCQ retinal toxicity will be calculated, accounting for the competing risk of death. Hazard ratios for each risk factor will be calculated for the risk of HCQ retinopathy, after adjusting for confounders. We will also estimate the risk of HCQ retinal toxicity progression over 5 years. ETHICS AND DISSEMINATION: This study has received approval from the University of British Columbia Clinical Research Ethics Board (H20-00736) and the Vancouver Coastal Health Research Institute.

The "microwave oven" practice in Brazil.

This article presents a forensic case of an unusual illegal cremation of a person using a process colloquially known as the "microwave oven" practice in Brazil. The microwave process involves two actions: placing the victim in a tire stack and then setting the structure on fire using flammable substances to accelerate the progression. A similar practice, identified as "necklacing", has also been reported in other countries such as South Africa. This report presents a case of microwave oven cremation of a body found in a rural area of Minas Gerais, Brazil. The forensic work helped determine the biological profile and identity of the victim using radiological comparisons. Although the microwave oven cremation practice is rare, it can impose challenges for investigators. Therefore, fully understanding this practice can be helpful to the academic and forensic communities.

Sintomas de depressão, risco nutricional e capacidade funcional em idosos longevos / Depression symptoms, nutritional risk and functional capacity in longlived ederly / Sintomas de depression, riesgo nutritional y capacidad funcional en personas mayores a largo plazo

Objetivou-se avaliar a relação entre sintomas de depressão, risco nutricional e capacidade funcional com características sociais, econômicas, demográficas e de saúde, em idosos longevos. Trata-se de uma pesquisa transversal, realizada em quatro municípios do estado de São Paulo. A relação entre as variáveis foi obtida por meio da técnica de Análise de Correspondência Múltipla. Foram avaliados 103 idosos, a maioria do sexo feminino, com idade entre 80 e 90 anos e com até quatro anos de estudo. Os resultados evidenciam a correspondência entre a presença de sintomas de depressão, risco nutricional, comprometimento funcional, baixa escolaridade e inadequada autoavaliação de saúde. Nota-se, portanto, a necessidade de uma abordagem interdisciplinar, e o desenvolvimento de políticas públicas direcionadas aos muito idosos, oferecendo atenção necessária para a redução do risco de depressão, de desnutrição e na melhoria da funcionalidade dos idosos longevos, que levem a um impacto positivo em sua qualidade de vida (AU).

Persistent Effect of Advanced Glycated Albumin Driving Inflammation and Disturbances in Cholesterol Efflux in Macrophages.

Advanced glycated albumin (AGE-albumin) impairs cholesterol efflux and contributes to inflammation in macrophages. The current study evaluated: (1) the persistence of the deleterious effect of AGE-albumin in cholesterol efflux and in inflammation, and (2) how metabolic control in diabetes mellitus (DM) contributes to attenuate the deleterious role of AGE-albumin in macrophage cholesterol homeostasis. Methods: AGE-albumin was produced in vitro or isolated from uncontrolled DM subjects' serum before (bGC) and after improved glycemic control (aGC). Albumin samples were incubated with bone marrow-derived macrophages and 14C-cholesterol efflux or LPS- induced cytokine secretion were determined immediately, or after cell resting in culture media alone. The ABCA-1 degradation rate was determined after cell incubation with cycloheximide, and ABCA1 protein level by immunoblot. Oil Red O staining was used to assess intracellular lipid accumulation. Results: A persistent effect of AGE-albumin was observed in macrophages in terms of the secretion of inflammatory cytokines and reduced cholesterol efflux. HDL-mediated 14C-cholesterol efflux was at least two times higher in macrophages treated with aCG-albumin as compared to bGC-albumin, and intracellular lipid content was significantly reduced in aGC-albumin-treated cells. As compared to bGC-albumin, the ABCA-1 protein content in whole cell bulk was 94% higher in aCG-albumin. A 20% increased ABCA-1 decay rate was observed in macrophages treated with albumin from poorly controlled DM. AGE-albumin has a persistent deleterious effect on macrophage lipid homeostasis and inflammation. The reduction of AGEs in albumin ameliorates cholesterol efflux.

It emphasizes whether the case was analyzed according to the Therapeutic Guidelines for Femoral Neck Fractures, which demonstrated the importance of applying systematization for differentiated care for elderly patients diagnosed with femoral fractures, considering that the elderly population is living longer, and falls are one of the adverse events most frequently affecting such population, followed by fracture. Conclusion: This study aims at contributing as a relevant management and care instrument for the institution of any surgical center that aims at speeding up discharge time, minimizing the risk of complications, reducing costs, and favoring the quality of life of elderly patients with femur fracture from the systematization of perioperative nursing care.

DYNAMIC POSTURAL BALANCE IS MEDIATED BY ANTHROPOMETRY AND BODY COMPOSITION IN OLDER WOMEN.

OBJECTIVE: To investigate the relationship between anthropometry and body composition with dynamic postural balance in elderly women with low bone mineral density (BMD). METHODS: 45 older women (≥ 60 years), low BMD and nutritional diagnosis of low weight to overweight. For the assessment of body composition, Dual energy X-ray emission densitometry and anthropometric examination were used to measure: body mass (kg), height (cm) and BMI (k/m2). The assessment of dynamic postural balance was performed by the mini Balance Master Evaluation System clinical test and the computerized Balance Master® System test by the Sit to Stand and Step Up/Over tests. RESULTS: There was a negative correlation between miniBESTest (r = - 0.566; p ≤ 0.001) and time to ascend and descend step (r = - 0.393; p ≤ 0.007) with fat mass, and positive correlation with miniBESTest (r = 0.526; p ≤0.001) and time to go up and down a step with muscle mass (r = 0.297; p ≤ 0.04). As for anthropometric variables, only height showed a positive correlation (r = 0.296; p ≤ 0.04) with the speed in the sit and stand test. CONCLUSION: Lean mass reduces postural oscillations; in contrast, fat mass negatively interfered with dynamic postural balance in women with low BMD. Height was related to dynamic postural balance, the taller the elderly, the worse their balance.

OBJETIVO: Investigar a relação da antropometria e composição corporal com o equilíbrio postural dinâmico em idosas com baixa Densidade Mineral Óssea (DMO). MÉTODOS: 45 idosas (≥ 60 anos), baixa DMO e diagnóstico nutricional entre baixo peso e sobrepeso. Para a avaliação da composição corporal utilizou-se a densitometria por emissão de raios x de dupla energia e exame antropométrico para aferir: massa corporal (kg), estatura (cm) e índice de massa corporal (IMC) (k/m2). A avaliação do equilíbrio postural dinâmico foi realizada pelo teste clínico mini Balance Master Evaluation System, pelo teste computadorizado Balance Master ® System e pelos testes Sit-to-Stand e Step Up/Over. Resultados: Houve correlação negativa do miniBESTest (r = − 0,566; p ≤ 0,001) e tempo de subir e descer um degrau (r = − 0,393; p ≤ 0,007) com a massa gorda, e correlação positiva do miniBESTest (r = 0,526; p ≤ 0,001) e tempo de subir e descer um degrau com a massa muscular (r = 0,297; p ≤ 0,04). Quanto às variáveis antropométricas, apenas a estatura apresentou correlação positiva (r = 0,296; p ≤ 0,04) com a velocidade no teste de sentar-se e levantar-se. CONCLUSÃO: A massa magra reduz as oscilações posturais. Em contrapartida, a massa gorda interfere de forma negativa no equilíbrio postural dinâmico de mulheres com baixa DMO. A estatura esteve relacionada ao equilíbrio postural dinâmico: quanto mais altas as idosas pior era seu equilíbrio.

Serum albumin modified by carbamoylation impairs macrophage cholesterol efflux in diabetic kidney disease.

BACKGROUND AND AIMS: Abnormalities in lipid metabolism, accumulation of uremic toxins and advanced glycation end products may contribute to worsening atherosclerosis. This study characterized the glycation and carbamoylation profile of serum albumin isolated from individuals with diabetic kidney disease and its influence on cholesterol efflux. MATERIAL AND METHODS: 49 patients with type 2 diabetes (T2DM) and different eGFR evaluated glycation and carbamoylation profile by measurement of carboxymethyl lysine (CML) and carbamoylated proteins (CBL) in plasma by ELISA, homocitrulline (HCit) in plasma by colorimetry. In the isolated albumins, we quantified CBL (ELISA) and total AGE and pentosidine by fluorescence. Macrophages were treated with albumin isolated, and 14C-Cholesterol efflux mediated by HDL2 or HDL3 was measured. Kruskal-Wallis test, Jonckheere-Terpstra test and Brunner's posttest were used for comparisons among groups. RESULTS: Determination of CML, HCit, CBL in plasma, as total AGE and pentosidine in albumins, did not differ between groups; however, CBL in the isolated albumins was higher in the more advanced stages of CKD (p=0.0414). There was reduction in the 14C-cholesterol efflux after treatment for 18h with albumin isolated from patients with eGFR<60mL/min/1.73m2 compared with control group mediated by HDL2 (p=0.0288) and HDL3 (p<0.0001), as well as when compared with eGFR ≥60mL/min/1.73m2 per HDL2 (p=0.0001) and HDL3 (p<0.0001). Treatment for 48h showed that eGFR<15mL/min/1.73m2 had a lower percentage of 14C-cholesterol efflux mediated by HDL2 compared to control and other CKD groups (p=0.0274). CONCLUSIONS: Albumins isolated from individuals with T2DM and eGFR<60mL/min/1.73m2 suffer greater carbamoylation, and they impair the cholesterol efflux mediated by HDL2 and HDL3. In turn, this could promote lipids accumulation in macrophages and disorders in reverse cholesterol transport.
