Nutritional Parameters in Early and Late Kidney Transplantation.

BACKGROUND: Kidney transplantation (KT) has the advantage of providing a better quality of life and freedom for the patient. However, nutritional changes can occur, with clinical repercussions. The aim of the study was to compare the nutritional status in the initial and late post-KT period. METHODS: A cross-sectional study was conducted involving 169 outpatients post-KT. Clinical, demographic, biochemical, food intake, handgrip strength (HGS), and anthropometric data were collected from medical records for the first nutritional care after KT. Statistical tests were performed to compare the groups according to the time of KT: early (≤1 year) and late (>1 year). The level of significance adopted was 5%. RESULTS: The median age of the patients was 46 years (range, 38-57), 50.3% were men, and it was observed that 66.9% underwent KT with a deceased donor. There was a higher prevalence of diabetes mellitus (42.6% vs 23.5%; P = .011), and higher body mass index (28.80 ± 7.26 vs 26.51 ± 6.62 kg/m2; P = .046), arm muscle circumference (25.84 ± 4.63 vs 24.09 ± 3.36 cm; P = .019), and HGS (26.97 ± 10.70 vs 20.21 ± 10.83 kg; P = .010) in patients with late KT. Linear regression analysis showed that at each log of time, there was an increase of 1.90 kg in HGS (P = .045) and 0.48 cm (P = .036) in mid-arm muscle circumference. CONCLUSION: The present study demonstrated that late kidney transplantation was associated with higher values of body mass index, mid-arm muscle circumference, and HGS.

Effect of doxorubicin on cardiac lipid metabolism-related transcriptome and the protective activity of Alda-1.

The use of doxorubicin (DOX) as an antineoplastic drug is compromised by its cardiotoxicity risk. Although several mechanisms have been proposed for DOX-induced cardiac dysfunction, there is still increased interest in assessing its effects. Likewise, it is important to find protocols that can prevent or minimize the side effects of DOX without hindering its antitumor activity. Thus, this study was designed to investigate the molecular mechanisms underlying DOX cardiotoxicity, with a special focus on cardiac energy metabolism and the ability of Alda-1 (ALDH2 agonist) to prevent DOX-induced cardiac alterations. We explored the effects of DOX on the histological morphology of the myocardium, on lipid profile, and on the expression of genes related to fatty acid metabolism, in the presence and absence of Alda-1 (8 mg/kg body weight; b.wt.). Two DOX treatment protocols were used: a single dose of DOX (4 mg/kg b.wt.); four doses of DOX (4 mg/kg b.wt.), one dose/week, for 4 weeks. Treatment with DOX caused a progressive injury in the cardiac tissue and an increase in the blood total cholesterol, high-density lipoproteins, very low-density lipoproteins and triglyceride, as well as an up-regulation of FABP4 (DOX and DOX + Alda-1 groups) and Slc27a2 (in DOX-treated animals). Alda-1 administration promoted reduction in the severity of the histopathological injuries (after single dose of DOX) and Slc27a2 overexpression was restored. In conclusion, the study revealed novel insights regarding the development of DOX-mediated cardiomyopathy, indicating a relationship between DOX exposure and FABP4 and Slc27a2 overexpression, and confirmed the cardioprotective effect of Alda-1.

Associations among body composition, inflammatory profile and disease extent in ulcerative colitis patients.

OBJECTIVE: The aim of our study was to assess body composition status and its association with inflammatory profile and extent of intestinal damage in ulcerative colitis patients during clinical remission. METHOD: This is a cross-sectional study in which body composition data (phase angle [PhA], fat mass [FM], triceps skin fold thickness [TSFt], mid-arm circumference [MAC], mid-arm muscle circumference [MAMC], adductor pollicis muscle thickness [APMt]), inflammatory profile (C-reactive protein [CRP], a1-acid glycoprotein, erythrocyte sedimentation rate [ESR]) and disease extent were recorded. RESULTS: The mean age of the 59 patients was 48.1 years; 53.3% were women. Most patients were in clinical remission (94.9%) and 3.4% was malnourished according to body mass index. PhA was inversely correlated with inflammatory markers such as CRP (R=-0.59; p<0.001) and ESR (R=-0.46; p<0.001) and directly correlated with lean mass: MAMC (R=0.31; p=0.01) and APMt (R=0.47; p<0.001). Lean mass was inversely correlated with non-specific inflammation marker (APMt vs. ESR) and directly correlated with hemoglobin values (MAMC vs. hemoglobin). Logistic regression analysis revealed that body cell mass was associated with disease extent (OR 0.92; 95CI 0.87-0.97; p<0.01). CONCLUSION: PhA was inversely correlated with inflammatory markers and directly correlated with lean mass. Acute inflammatory markers were correlated with disease extent. Body cell mass was associated with disease extent.

Resumo Objetivo: Avaliar a composição corporal de pacientes portadores de retocolite ulcerativa em remissão clínica e sua associação com o perfil inflamatório e a extensão da lesão intestinal. Método: Foi realizado um estudo transversal. Os dados relacionados à composição corporal foram ângulo de fase (AF), massa adiposa (MA), dobra cutânea triciptal (DCT), circunferência do braço (CB), circunferência muscular do braço (CMB) e espessura do músculo adutor do polegar (EMAP). O perfil inflamatório foi avaliado através da dosagem da proteína-C reativa (PCR), a1-glicoproteína ácida e velocidade de hemossedimentação (VHS) e a extensão da doença foi avaliada de acordo com o exame endoscópico. Resultados: Foram avaliados 59 pacientes. A média de idade foi de 48,1 anos e 53,3% eram mulheres. A maioria dos pacientes (94,9%) estava em remissão clínica da doença e 3,4% foi classificada como desnutrida de acordo com o IMC. Observou-se uma correlação inversa entre AF e marcadores inflamatórios como a PCR (R=-0,59; p<0,001) e VHS (R=-0,46; p<0,001) e uma correlação direta entre AF e os indicadores de massa magra como CMB (R=0,31; p=0,01) e EMAP (R=0,47; p<0,001). A massa magra foi inversamente correlacionada com marcadores inflamatórios não específicos, como a VHS, e diretamente correlacionada com a hemoglobina. De acordo com a análise de regressão logística, a massa celular corporal foi associada com extensão da lesão intestinal (OR 0,92; IC95% 0,87-0,97; p<0,01). Conclusão: AF foi inversamente correlacionado com marcadores inflamatórios e diretamente correlacionado com a massa magra. Marcadores inflamatórios de fase aguda e massa celular corporal foram correlacionados com extensão da lesão intestinal.
