Proteins, especially plant proteins, may reduce inflammation among adults with chronic kidney disease (CKD). This systematic review and meta-analysis were conducted to evaluate the effect protein types (animal or plant) have on inflammation markers (CRP, IL-6, TNF-α) among adults with varying stages of CKD. The Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) was conducted to identify articles from inception until January 2021, utilizing six databases. Controlled trials that compared the effects of different protein types were analyzed using random-effects meta-analysis. Quality assessment and risk of bias of the included articles were assessed by using Cochrane risk of bias instrument and ROBINS-I. Out of the 10 studies that met the criteria, there was a decreasing trend in CRP levels when consuming plant proteins compared to animal proteins among non-dialysis participants. There was a statistically significant decrease when comparing animal proteins to unspecified proteins in CRP levels among dialysis participants [Hedges’ g = 2.11; 95% CI 1.12, 3.11; p ≤ 0.001], favoring unspecified proteins. Furthermore, animal proteins (eggs, red meat) showed increasing trends in CRP levels compared to whey protein isolate. Caution must be considered regarding these results as controlled, non-randomized, trials were included in the analysis, which may have contributed to high risk of bias. Future research should focus on protein types and the impact they have on kidney disease progression and inflammation markers.

GSTM1-null genotype was associated with a lower risk of developing acute leukemia (P = 0.013; OR: 0.31; CI: 0.12-0.80), while GSTP1-GG variants displayed an increased risk (P = 0.01; OR: 3.9; CI: 1.85-8.2). However, no differences were found for GSTT1 gene. Conclusion These preliminary results, to be validated in a larger population from Argentina, suggest that the development of pediatric leukemia may be differentially influenced by polymorphic variants in GST genes.

Comparative genomic hybridization (CGH) was used to detect chromosomal imbalances in 20 patients with a diagnosis of myelodysplastic syndrome (MDS) and acute myeloid leukaemia (AML). The results obtained were compared with G-banding analysis. This last methodology showed 50% of cases with clonal abnormalities whereas CGH detected 70% of cases with copy number changes. Gains were more frequent than losses and constituted 66% of total changes detected. The most common gains included chromosomes 21 and chromosome region 18p for AML and chromosome 17 and region 1p33p35 for MDS. Losses represent 34% of changes and the regions involved were 5q31q32, 7q22, 7p12 and 13q21q22. CGH revealed additional chromosome imbalances in 12 of 20 cases (60%) which were not detected by traditional cytogenetic studies, demonstrating complex karyotype in 50% (6/12). Combination of CGH and G-banding provides an efficient method to identify critical regions present in the malignant clone, which is of great value in the prognosis and outcome of myeloid neoplasias.

The aim of this study was to evaluate the levels of chemical markers in raw cacao beans in two clones (introduced and regional) in Colombia over several years. Multivariate statistical methods were used to analyze the flavanol monomers (epicatechin and catechin), flavanol oligomers (procyanidins) and methylxanthine alkaloids (caffeine and theobromine) of cocoa samples. The results identified genotype as the main factor contributing to cacao chemistry, although significant differences were not observed between universal and regional clones in PCA. The univariate analysis allowed us to establish that EET-96 had the highest contents of both flavanol monomers (13.12 ± 2.30 mg/g) and procyanidins (7.56 ± 4.59 mg/g). In addition, the geographic origin, the harvest conditions of each region and the year of harvest may contribute to major discrepancies between results. Turbo cocoa samples are notable for their higher flavanol monomer content, Chigorodó cocoa samples for the presence of both types of polyphenol (monomer and procyanidin contents) and the Northeast cocoa samples for the higher methylxanthine content. We hope that knowledge of the heterogeneity of the metabolites of interest in each clone will contribute to the generation of added value in the cocoa production chain and its sustainability.

La enfermedad renal crónica (ERC o también llamada CKD por sus siglas en inglés) es considerada un problema de salud pública. En los Estados Unidos, se estima que 37 millones de adultos, que equivale al 15% de la población, padece esta enfermedad (CDC 2020). La enfermedad renal crónica es una enfermedad caracterizada por la pérdida gradual de la función renal. El consumir una dieta adecuada y balanceada puede prevenir el progreso de esta enfermedad (NKF, n.d.; Rysz et al. 2017). Por ende, el propósito de este artículo es proporcionar una descripción general de la ERC y consideraciones nutricionales.

Chronic kidney disease (CKD) is considered a public health issue within the United States because an estimated 37 million adults or 15% of the population have this disease. CKD is a disease characterized by the gradual loss of kidney function. Early prevention techniques such as a well-balanced diet reduce the progression of this disease. The purpose of this new 6-page article is to provide an overview of CKD and nutritional considerations.
