Global filtration rate

Linicene Rosa do Nascimento, Caroline Pereira Domingueti
Diabetic kidney disease (DKD) is a chronic complication of diabetes mellitus associated with significant morbidity and mortality regarded as a global health issue. MicroRNAs - small RNA molecules responsible for the post-transcriptional regulation of gene expression by degradation of messenger RNA or translational repression of protein synthesis - rank among the factors linked to the development and progression of DKD. This study aimed to offer a narrative review on investigations around the use of microRNAs in the diagnosis, monitoring, and treatment of DKD...

There is controversy regarding the utility of left ventricular (LV) mechanics assessed by feature-tracking steady-state free-precession (FT-SSFP), a readily implementable technique in clinical practice. In particular, whether LV mechanics assessed by FT-SSFP predicts outcomes in subjects with heart failure (HF) with reduced ejection fraction (HFrEF), with preserved ejection fraction (HFpEF), or without HF is unknown. We aimed to assess whether LV mechanics measured with FT-SSFP cine magnetic resonance imaging (MRI) predicts adverse outcomes...

Background Intestinal parasites cause significant morbidity and impact human development with an enormous global burden. Diagnosis of intestinal parasites by conventional methods has several limitations. The gauze filtration technique is a relatively simple method that has been shown to identify intestinal parasites with a high sensitivity and specificity. The aim of this study was to determine the diagnostic value of this technique as compared to more conventional methods in a large acclaimed laboratory within Pakistan...

We sought to investigate the association between intraoperative urine output and postoperative acute kidney injury (AKI) in patients undergoing radical and partial nephrectomy. We retrospectively reviewed data of 742 patients. Postoperative AKI was defined by the Kidney Disease: Improving Global Outcomes criteria. The relationship between intraoperative urine output and the risk of AKI was evaluated by multivariable logistic regression analysis in radical and partial nephrectomy, separately. Minimum P-value approach was used to find the optimal threshold of intraoperative oliguria associated with the risk of AKI...

Close monitoring of estimated glomerular filtration rate (eGFR) is important for early recognition of worsening renal function to prevent further deterioration. Safe conversion from twice-daily tacrolimus (TD-Tac) to once-daily tacrolimus (OD-Tac) has been reported, but the effects on eGFR are contrasting. The aim of our study is to evaluate long-term stability of eGFR after 1:1 conversion from TD-Tac to OD-Tac and the effects on serum cytokine blood levels. Forty-six consecutive kidney transplant recipients treated with TD-Tac 3 to 5 years post-transplant, with stable renal function, were enrolled in the study (2009-2011)...

OBJECTIVE: In cross-sectional studies, elevated osteopontin (OPN) levels have been proposed to reflect, and/or precede, progressive organ damage and disease severity in systemic lupus erythematosus (SLE). We aimed, in a cohort of patients with recent-onset SLE, to determine whether raised serum OPN levels precede damage and/or are associated with disease activity or certain disease phenotypes. METHODS: We included 344 patients from the Systemic Lupus International Collaborating Clinics (SLICC) Inception Cohort who had 5 years of followup data available...

The introduction in the past few years of advanced optical coherence tomography (OCT) techniques has greatly increased our understanding of the choroid, which is the most important vascular layer of the eye. Our study aimed to assess choroidal thickness by using swept-source OCT (SS-OCT) in essential hypertensive patients (EHs) with and without early-stage chronic kidney disease (CKD). We enrolled 100 EHs, of whom 65 were without kidney damage, and 35 had stage 1-3 CKD. In all of the participants, SS-OCT and a routine biochemical workup were performed...

BACKGROUND: The incidence of end-stage renal disease (ESRD) is increasing in elderly patients with chronic kidney disease (CKD). This contradicts the general notion that elderly people are more likely to die than to ever reach ESRD. And racial disparity in relation to age on kidney disease outcomes has always been a subject of research interest. AIMS: We investigated the effect of age on outcome in a cohort with stages 3-5 CKD patients by age category. METHODS: A total of 430 patients with a mean age of 65...

BACKGROUND: Sickle cell trait (SCT) is common among African Americans and has been historically considered to be benign. Recently, SCT has been associated with an increased risk for chronic kidney disease (CKD) and cardiovascular disease in the general population. Our understanding of SCT has been extrapolated largely from data of patients with sickle cell disease (SCD). Notably, in SCD, the outcomes differ by sex. The effect of SCT on cardiovascular risk in the African American CKD population is unknown, and the interaction between SCT and sex on cardiovascular risk has not been investigated...

Chronic kidney disease (CKD) affects ~10% of the global population, with considerable ethnic differences in prevalence and aetiology. We assemble genome-wide association studies of estimated glomerular filtration rate (eGFR), a measure of kidney function that defines CKD, in 312,468 individuals of diverse ancestry. We identify 127 distinct association signals with homogeneous effects on eGFR across ancestries and enrichment in genomic annotations including kidney-specific histone modifications. Fine-mapping reveals 40 high-confidence variants driving eGFR associations and highlights putative causal genes with cell-type specific expression in glomerulus, and in proximal and distal nephron...

Analysing the effect water temperature has on Daphnia magna is essential in anticipating the impact climate change will have on this freshwater zooplanktonic keystone species. While many authors have followed this line of research, few have covered an extensive temperature range or complex temperature change scenarios. Global warming is mostly associated with increased extreme temperature events, such as heat waves, as well as earlier and more intense thermal stratification. Both of these events may directly influence D...

Renal perfusion, which depends on cardiac function, is a factor conditioning the work of kidneys. The objective of the study was to assess the influence of cardiac function, including left ventricular contractility and relaxation, on renal cortical perfusion in patients with hypertension and chronic kidney disease treated pharmacologically. There were 63 patients (7 F and 56 M; aged 56 ± 14) with hypertension and stable chronic kidney disease enrolled into the study. Serum cystatin C, with estimated glomerular filtration rate (eGFR), ambulatory blood pressure monitoring, carotid intima-media thickness (cIMT), echocardiography with speckle tracking imaging and the calculation of global longitudinal strain (GLS), diameter of vena cava inferior (VCI), and an ultrasound dynamic tissue perfusion measurement of the renal cortex were performed...

PURPOSE: Peptide receptor radionuclide therapy (PRRT) is mostly administered using a fixed injected activity (IA) per cycle. This empiric regime results in highly variable absorbed doses to the critical organs and undertreatment of the majority of patients. We conceived a personalized PRRT protocol in which the IA is adjusted to deliver a prescribed absorbed dose to the kidney, with the aim to safely increase tumour irradiation. We herein report on the initial results of our prospective study of personalized PRRT, the P-PRRT Trial (NCT02754297)...

Microplastic fibers (MPF) are a ubiquitous marine contaminant, making up to 90% of global microplastic concentrations. Imaging flow cytometry was used to measure uptake and ingestion rates of MPF by blue mussels (Mytilus edulis). Mussels were fed a diet of Rhodomonas salina and MPF concentrations up to 30 MPF mL-1 , or 0.374% of available seston. Filtration rates were greatly reduced in mussels exposed to MPF. Uptake of MPF followed a Holling's Type II functional response with 95% of the maximum rate (5227 MPF h- 1 ) occurring at 13 MPF mL-1 ...

The search of personalized treatment for a subject with immunoglobulin A nephropathy (IgAN) is appealing since the individual long-term outcome is highly variable in spite of common mild clinical signs such as microscopic haematuria, moderate proteinuria and slightly reduced glomerular filtration rate (GFR). The only risk factor considered by the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines to target corticosteroid/immunosuppressive treatment in IgAN is proteinuria persistently >1 g/day despite 3-6 months of optimized supportive care...

Introduction: Chronic kidney disease (CKD) and acute kidney injury (AKI) are strongly associated with excess morbidity and mortality and frequently co-occur in critically ill septic patients, but how their interplay affects clinical outcomes is not well elucidated. Methods: We conducted a single-center, retrospective cohort study of 2632 adult patients admitted to the intensive care unit (ICU) with severe sepsis or septic shock. Subjects were classified into 6 groups according to baseline CKD (no-CKD: estimated glomerular filtration rate [eGFR] ≥60; CKD: eGFR 15-59 ml/min per 1...
