Published: March 2022

Context: Malnutrition has a negative impact on patients with cancer. Identifying risk, nutritional status, and functional capacity can contribute to adequate and early nutritional therapy, which can reduce unfavorable clinical outcomes.

Objective: To evaluate and summarize the main instruments of nutritional assessment and functional capacity and associate their results with clinical outcomes in hospitalized patients with cancer.

Data Sources: A systematic search was performed in the PubMed/MEDLINE, Embase, SciELO, and LILACS databases. Studies in which researchers evaluated and compared screening, nutritional assessment, and functional capacity instruments and their associations with clinical outcomes were included.

Data Extraction: The data were extracted by 2 independent reviewers.

Results: A total of 29 studies met the inclusion criteria (n = 20 441 individuals). The Nutritional Risk Screening-2002 (NRS-2002) and Patient-Generated Subjective Global Assessment (PG-SGA) were the most common tools used for nutritional assessment. High nutritional risk according to the NRS-2202 and worse nutritional status according to the PG-SGA and Subjective Global Assessment were positively associated with a longer hospital stay and mortality. Low functional capacity, according to handgrip strength, was associated with longer hospital stay and nutrition impact symptoms.

Conclusions: Tools such as the NRS-2002, PG-SGA, Subjective Global Assessment, and handgrip strength assessment are efficacious for assessing unfavorable clinical outcomes in hospitalized patients with cancer.

Introduction: We aimed to present the changes that may occur in pulmonary functions in children who experienced more severe coronavirus disease 2019 (COVID-19) during long-term follow-up.

Methodology: A prospective longitudinal observational cohort study was conducted with 34 pediatric patients (7-18 years) who were hospitalized with COVID-19 infection (moderate n = 25, severe n = 9), and followed up at our Pediatric Infection Outpatient Clinic for approximately two years. Pulmonary function tests (PFTs) were performed using spirometry.

Blood-based epigenome-wide association study and prediction of alcohol consumption.

Clin Epigenetics

January 2025

Centre for Genomic and Experimental Medicine, Institute of Genetics and Cancer, University of Edinburgh, Edinburgh, UK.

Alcohol consumption is an important risk factor for multiple diseases. It is typically assessed via self-report, which is open to measurement error through recall bias. Instead, molecular data such as blood-based DNA methylation (DNAm) could be used to derive a more objective measure of alcohol consumption by incorporating information from cytosine-phosphate-guanine (CpG) sites known to be linked to the trait.

This study investigated the effects of non-thermal atmospheric plasma (NTAP) treatment on the growth, chemical composition, and biological activity of geranium (Pelargonium graveolens L'Herit) leaves. NTAP was applied at a frequency of 13.56 MHz, exposure time of 15 s, discharge temperature of 25 °C, and power levels (T1 = 50, T2 = 80, and T3 = 120 W).

Differentiation of stem cells into chondrocytes and their potential clinical application in cartilage regeneration.

Histochem Cell Biol

January 2025

Department of Forensic Medicine and Forensic Toxicology, Medical University of Silesia, 18 Medyków Street, 40-752, Katowice, Poland.

Cartilage diseases and injuries are considered difficult to treat owing to the low regenerative capacity of this tissue. Using stem cells (SCs) is one of the potential methods of treating cartilage defects and creating functional cartilage models for transplants. Their ability to proliferate and to generate functional chondrocytes, a natural tissue environment, and extracellular cartilage matrix, makes SCs a new opportunity for patients with articular injuries or incurable diseases, such as osteoarthritis (OA).
