Acute kidney injury as a key predictor of cardiovascular events in chronic kidney disease patients: the CKD-REIN study.

Background And Hypothesis: Cardiovascular diseases are a leading cause of morbidity and mortality in patients with chronic kidney disease (CKD). Acute kidney injury (AKI) has been increasingly recognized as a potential exacerbating factor for cardiovascular events in these patients. The CKD-REIN study aims to explore the relationship between AKI and the risk of major adverse cardiovascular events (MACE) in a cohort of CKD patients.

Development, Content Validity and Usability of a Self-Assessment Instrument for the Lifestyle of Breast Cancer Survivors in Brazil.

Background/objectives: Breast cancer is the most common cancer among women globally, and it negatively impacts diet and quality of life, increasing the risk of recurrence. Adhering to World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) lifestyle guidelines, such as healthy eating habits and nutritional status, can help in primary and secondary cancer prevention. However, no questionnaire was found for self-assessment of these guidelines for the Brazilian population.

Symptom Burden and Its Impact on Quality of Life in Patients With Moderate to Severe CKD: The International Chronic Kidney Disease Outcomes and Practice Patterns Study (CKDopps).

Rationale & Objective: Recent evidence suggests people with nondialysis chronic kidney disease (ND-CKD) experience a substantial burden of symptoms, but informative large-scale studies have been scarce. We assessed the prevalence of symptoms and the association of overall symptom burden with quality of life in patients with moderate to severe CKD.

Study Design: Cross-sectional study.

Predictors of daytime blood pressure, nighttime blood pressure, and nocturnal dipping in patients with chronic kidney disease.

Increasing attention has recently been paid to discrepancies between office and ambulatory blood pressure (BP) control in patients with chronic kidney disease (CKD), but information on mechanisms underlying circadian BP variations in CKD remains scarce. We described circadian BP patterns and their predictors in patients with CKD stages 1 to 5 referred for kidney function testing in a French tertiary hospital: 1122 ambulatory BP measurements from 635 participants. Factors associated with daytime and nighttime systolic BP (SBP) as well as with nocturnal SBP dipping (ratio of average nighttime to daytime SBP) were analyzed with linear mixed regression models.

Inflammation, but not skeletal muscle index, is associated with coronavirus disease 2019 mortality in patients with cancer.

The aim of this study was to analyse the clinical usefulness of the Patient-Generated Subjective Global Assessment short form (PG-SGA SF©) for nutritional screening in patients with head and neck cancer (HNC). This is a multicentre, cross-sectional study involving patients with HNC.

Conservative Kidney Management Practice Patterns and Resources in the United States: A Cross-Sectional Analysis of CKDopps (Chronic Kidney Disease Outcomes and Practice Patterns Study) Data.

Rationale & Objective: Conservative kidney management (CKM) is a viable treatment option for many patients with chronic kidney disease. However, CKM practices and resources in the United States are not well described. We undertook this study to gain a better understanding of factors influencing uptake of CKM by describing: (1) characteristics of patients who choose CKM, (2) provider practice patterns relevant to CKM, and (3) CKM resources available to providers.

Identification of Immunodominant Proteins of the SubProteome as Pan-Specific Vaccine Targets against Leishmaniasis.

is a wide-spectrum disease caused by parasites from genus. A well-modulated immune response that is established after the long-lasting clinical cure of leishmaniasis can represent a standard requirement for a vaccine. Previous studies demonstrated that causes benign disease and its antigens induce well-modulated immune responses in vitro.

Real-life Effectiveness of Omalizumab in Patients with Severe Allergic Asthma: RELIEF Study.

Nutritional status at hospital admission and prediction of clinical outcomes in children and adolescents with cancer: Results of the Brazilian survey on oncological nutrition in paediatrics.

Background: Changes in nutritional status are recognised as predictors of unfavourable outcomes in children and adolescents with cancer, particularly in developing countries. There have been no studies on children and adolescents with cancer from every region of Brazil or on the impact of nutritional status on clinical outcomes. The aim of this study is to assess the association between the nutritional status of children and adolescents with cancer and the prediction of clinical outcomes.

Association between functional aspects and health-related quality of life in patients with colorectal cancer: can handgrip strength be the measure of choice in clinical practice?

Purpose: We aimed to investigate the association between handgrip strength (HGS) and health-related quality of life (HRQoL) in patients with colorectal cancer (CRC). A cross-sectional study was conducted including CRC patients.

Methods: We performed an assessment of aspects of functional health using the criteria of frailty phenotype (defined by Fried et al.

Predictive validity of GLIM malnutrition diagnosis in patients with colorectal cancer.

Background: Considering that the validation of the Global Leadership Initiative on Malnutrition (GLIM) remains unclear in patients with colorectal cancer, the present study aimed to assess the agreement, accuracy, sensitivity, specificity, and prognostic effect of the GLIM on survival when compared with the Patient-Generated Subjective Global Assessment (PG-SGA).

Methods: Patients with colorectal cancer who were scheduled to undergo a routine abdominal computed tomography (CT) scan were recruited. Using the GLIM two-step approach, the patients were first screened for malnutrition by using the PG-SGA Short Form (score ≥3).

Performance of subjective global nutritional assessment in predicting clinical outcomes: Data from the Brazilian survey of pediatric oncology nutrition.

Background: Methods for assessing nutritional status in children and adolescents with cancer is a difficult in clinical practice. The study aimed to evaluate the performance of Subjective Global Nutritional Assessment (SGNA) in predicting clinical outcomes in children and adolescents with cancer in Brazil.

Methods: This was a prospective cohort multicenter study.

In-Depth Quantitative Proteomics Characterization of In Vitro Selected Miltefosine Resistance in .

Visceral leishmaniasis (VL) is a neglected disease caused by parasites. Although significant morbidity and mortality in tropical and subtropical regions of the world are associated with VL, the low investment for developing new treatment measures is chronic. Moreover, resistance and treatment failure are increasing for the main medications, but the emergence of resistance phenotypes is poorly understood at the protein level.

Nitric Oxide Resistance in () Involves Regulation of Glucose Consumption, Glutathione Metabolism and Abundance of Pentose Phosphate Pathway Enzymes.

In American Tegumentary Leishmaniasis production of cytokines, reactive oxygen species and nitric oxide (NO) by host macrophages normally lead to parasite death. However, some strains exhibit natural NO resistance. NO-resistant strains cause more lesions and are frequently more resistant to antimonial treatment than NO-susceptible ones, suggesting that NO-resistant parasites are endowed with specific mechanisms of survival and persistence.

Phase angle as a marker for muscle abnormalities and function in patients with colorectal cancer.

Background And Aims: Considering the applicability of phase angle (PhA) as a marker of muscle mass and function, we aimed to investigate whether PhA is a predictor of muscle abnormalities and function in patients with cancer.

Methods: In a sample of patients with colorectal cancer (CRC), PhA was obtained from measurements of resistance and reactance from bioelectrical impedance analysis. Computerized tomography imaging at the third lumbar vertebra was used to evaluate muscle abnormalities by quantifying skeletal muscle index (SMI) and skeletal muscle radiodensity (SMD).

Malnutrition Aggravates Alterations Observed in the Gut Structure and Immune Response of Mice Infected with .

Malnutrition is a risk factor for developing visceral leishmaniasis and its severe forms. Our group demonstrated that malnourished animals infected with had severe atrophies in lymphoid organs and T cell subpopulations as well as altered levels of thymic and splenic chemotactic factors, all of which resulted in dysfunctional lymphoid microenvironments that promoted parasite proliferation. Here, we hypothesize that malnutrition preceding parasite infection leads to structural and immunological changes in the gut mucosae, resulting in a failure in the immune response sensed in the intestine.

Urgent-start dialysis in patients referred early to a nephrologist-the CKD-REIN prospective cohort study.

Background: The lack of a well-designed prospective study of the determinants of urgent dialysis start led us to investigate its individual- and provider-related factors in patients seeing nephrologists.

Methods: The Chronic Kidney Disease Renal Epidemiology and Information Network (CKD-REIN) is a prospective cohort study that included 3033 patients with CKD [mean age 67 years, 65% men, mean estimated glomerular filtration rate (eGFR) 32 mL/min/1.73 m2] from 40 nationally representative nephrology clinics from 2013 to 2016 who were followed annually through 2020.

Muscle Mass Assessed by Computed Tomography at the Third Lumbar Vertebra Predicts Patient Survival in Chronic Kidney Disease.

Objective: Muscle mass is a key element for the evaluation of nutritional disturbances in patients with chronic kidney disease (CKD). Low muscle mass is associated with increased morbidity and mortality. The assessment of muscle mass by computed tomography at the third lumbar vertebra region (CTMM-L3) is an accurate method not subject to errors from fluctuation in the hydration status.
