Summary: In individuals with HIV infection, cystatin C and urine albumin to creatinine ratio are associated with all-cause mortality and/or cardiovascular events independently of baseline mGFR. Biomarkers were not predictive of changes in glomerular filtration rate over time.

Summary: Patients undergoing lung transplantation (LTx) experience a rapid decline in glomerular filtration rate (GFR) in the acute postoperative period. This study compared different equations for estimating GFR in LTx patients and found that equations based on plasma creatinine underestimated GFR decline, while equations based on plasma cystatin C overestimated GFR decline after LTx. The 2021 CKD-EPI combination equation had the most accurate estimation of GFR in both pre-LTx and post-LTx periods. Therefore, caution should be exercised when interpreting renal function based on GFR estimation equations in the acute postoperative period following LTx.

Summary: The study found independent associations between estimated glomerular filtration rate (eGFR) and albumin to creatinine ratio (ACR) with all-cause and cardiovascular mortality in Korean adults aged >= 50 years. When comparing eGFR performance, eGFR(cys) showed superior predictive accuracy for all-cause mortality compared to eGFR(MDRD) and eGFR(CKD-EPI).

Summary: The 2021 creatinine-based formula was found to be more accurate and precise compared to the 2009 formula in estimating glomerular filtration rate (eGFR) in Black individuals on antiretroviral therapy. However, it still had limitations in accurately estimating eGFR in certain ranges. Cystatin C-based eGFR may provide useful information in Black individuals with eGFR <60, regardless of the antiretroviral therapy regimen.

Summary: This study used a high-intensity functional training method, CCombat, to induce metabolic stress and evaluated its effects on hydration and kidney function. The results showed an increase in blood myoglobin, d-dimer levels, albuminemia, creatininemia, and cystatin C levels, as well as an increase in albuminuria, suggesting the potential use of microalbuminuria as a biomarker for evaluating hydration status changes during intensive exercise.

Summary: This study describes a novel creatinine muscle index (CMI) based on serum creatinine and cystatin C, which is associated with frailty and mortality in older adults. Lower CMI is linked to increased frailty and mortality, suggesting that creatinine filtration may serve as an index of muscle mass in clinical practice, particularly at low levels.

Summary: This study assessed the impact of IFCC calibration on cystatin C values and GFR estimations, finding a significant increase in cystatin C values and altered performance of GFR estimating equations following incorporation of the IFCC standard. The recommendation is for clinical laboratories and providers to update the equation used for cystatin C-based estimation of GFR after adopting the IFCC reference standard.

Summary: This study found impaired kidney function to be a critical risk factor for dementia, with the use of cystatin C strengthening the relationship between CKD and dementia. It highlights the significant value of preserving kidney function to reduce the risk of dementia and suggests considering cystatin C measurement as part of clinical practice in evaluating dementia risk.

Summary: This study evaluated the correlations between CLvan and GFRcr, and CLvan and GFRcys in paediatric patients, with results showing that serum cystatin C-based GFR correlates better with vancomycin clearance than GFRcr, suggesting the potential for better prediction models. Further prospective studies are needed to validate this in a large paediatric population.

Summary: Plasma disappearance curves using multiple blood samples are a recognized reference method for measuring glomerular filtration rate (GFR). However, there is no consensus on the protocol for this type of measurement. The fitting method used to calculate the GFR from the concentration-time curve strongly influences the reported GFR values, with the full concentration-time method being less robust than expected.

Summary: This article highlights the importance of kidney lifespan in understanding chronic kidney disease. Adaptive adjustments of nephrons are crucial for maintaining kidney function and structure, and the progression of kidney disease due to nephron loss is closely related to individual kidney function status.

Summary: SGLT2is have been shown to have significant renal protective effects in patients with cardiovascular disease, CKD (especially with albuminuria), or heart failure. The mechanisms behind this protection include reduction in intraglomerular pressure, diuretic effects leading to lower albuminuria and improved renal decongestion, reduction in renal oxygen consumption, improvement in heart failure status, and lower risk of acute renal injury. These effects may work in combination and vary in their contribution based on patient characteristics.

Summary: In May 2021, despite the availability of COVID-19 vaccines, 28% of the French population expressed willingness to participate in a COVID-19 vaccine clinical trial. Mistrust in health actors contributes to a decrease in participation intention. Attitudes towards COVID-19 vaccination can predict attitudes towards participation in a COVID-19 vaccine clinical trial.

Summary: This study conducted sentiment analysis on French Twitter users' opinions on COVID-19 vaccines and found that keywords related to conspiracy theories, pharmaceutical companies, and alternative treatments revealed skepticism towards the vaccines. The analysis showed that vaccines were perceived as having a political agenda and COVID-19 was seen as a commercial argument for pharmaceutical companies. Twitter can be a valuable tool for investigating vaccine mistrust and this research provides effective tools for health authorities to better understand the risk of vaccine mistrust.
