Objective: Malnutrition is common among cancer patients and even more prevalent in olderadults. Although its association with mortality risk is well established, further studies in LatinAmerica are needed to delve deeper into this relationship. This study aimed to evaluate theassociation between malnutrition and mortality risk among Peruvian older adult patients (≥ 60 years)with cancer. Materials and methods: Comprehensive geriatric assessment (CGA) records of olderadult patients with cancer evaluated at the Geriatrics Department of Hospital Almenara in Lima,Peru, from 2018 to January 2024, were reviewed. Nutritional status was assessed using the MiniNutritional Assessment Short Form (MNA-SF), which classifies patients into three groups: normal,at risk of malnutrition, or malnourished. This retrospective observational study comprised bothcases (patients at risk of malnutrition or malno...

Aim: CKD-EPIcr (Chronic Kidney Disease Epidemiology Collaboration creatinine) and BIS1 (Berlin Initiative Study) are two serum creatinine-based formulae for the estimation of glomerular filtration rate (GFR). However, their comparative accuracy in older people has not been well established. Our aim was to conduct a systematic comparative study of the accuracy of estimation of GFR in older people with these two formulae. Methods: We conducted a systematic search in Pubmed, EMBASE and Central databases on the validity of the CKD-EPIcr and BIS1 formulae in people aged 60 or more years. The search ranged from 2009 and 2012 for CKD-EPIcr and BIS1, respectively, until May 2017. The validity criterion for comparing the formulae was to have a P30 accuracy level equal to or greater than 80%. Results: Of 1295 identified studies, 16 met our inclusion criteria. Out of 16 studies reporting the accura...
