BACKGROUND: The end stage renal disease population has a 20 fold higher incidence of cardiovascular mortality compared to the overall population. The development of reno-cardiac syndrome in these patients will result in cardiovascular events to be the cause of 50% of fatalities. There is therefore a need to research improved therapeutic strategies to combat renal cardiac pathologies. Murine in vivo models contribute greatly to such research allowing for specific genetic modification and reduced miscellany, however there is currently no reliable model of reno-cardiac syndrome in the most common genetically modified mouse strain, the C57BL/6...

Objective: We assessed what predicts nutritional adequacy at day 14 following implantation of left ventricular assist device (LVAD). Method: We retrospectively reviewed the cases of 97 adult patients who underwent LVAD implantation at our institution from June 2011 to June 2016. We divided the patients into two groups based on the administered enteral nutrition (EN) calories on post-operative day (POD) 14: the EN calories of group SEN (sufficient enteral nutrition) were >80% of their total target calories, or the EN calories of group IEN (insufficient enteral nutrition) were <80% of their total target calories...

BACKGROUND/AIMS: Polycystic kidney disease (PKD) is a common, progressive, and heritable type of kidney disease. Although certain imaging modalities are useful for the diagnosis and staging of PKD, they cannot adequately monitor the severity of interstitial inflammation and fibrosis. Therefore, the present study evaluated the urinary level of liver-type fatty acid binding protein (L-FABP) as a marker of interstitial inflammation and fibrosis in PKD. METHODS: Male PCK/CrljCrl-Pkhd1pck/Crl (PCK) rats (n = 34) were used as an animal model of the PKD...

Our objectives were to assess the relationships between milk urea N (MUN), serum urea N (SUN), urine N (UN), and urinary urea N (UUN) in late-lactation cows fed N-limiting diets and compare these relationships with those previously established. Data were from a pen-based study in which 128 Holstein cows had been assigned to 1 of 16 pens in a randomized complete block design to assess the effects of diets containing 16.2, 14.4, 13.1, and 11.8% crude protein (CP, dry matter basis) during a 12-wk period. At least half of the cows in each pen were randomly selected to collect pen-level samples of serum and urine in wk 3, 7, and 11, when wk in lactation averaged 35, 39, and 43, respectively...

In recent reports, we have shown that optimized pretargeted radioimmunotherapy (PRIT) based on molecularly engineered antibody conjugates and 177 Lu-DOTA chelate (DOTA-PRIT) can be used to cure mice bearing human solid tumor xenografts using antitumor antibodies to minimally internalizing membrane antigens, GPA33 (colon) and GD2 (neuroblastoma). However, many solid tumor membrane antigens are internalized after antibody binding and it is generally believed that internalizing tumor membrane antigens are not suitable targets for PRIT...

Anemia is defined according to decreased blood hemoglobin concentration ([Hb]), which is considered a marker of low total red blood cell volume (RBCV). Alterations of plasma volume (PV) may also modify [Hb] without concomitant changes in RBCV. Since anemia and fluid retention are frequent complications of chronic kidney disease (CKD), we hypothesized that anemia during CKD may in part be related to expanded PV without a simultaneous decrease in RBCV. We quantified hemoglobin mass, RBCV, PV, and total blood volume (BV) using an automated carbon monoxide device in 40 consecutive stage 3-5 CKD patients not on dialysis and in seven healthy male controls of the same age range...

PURPOSE: As has been previously reported, the somatostatin receptor (SSTR) imaging agent [68 Ga]-labeled 1,4,7,10-tetraazacyclododecane-N,N',N″,N‴-tetraacetic acid-d-Phe(1)-Tyr(3)-octreotate ([68 Ga]DOTATATE) demonstrates lower uptake in normal organs in patients with a high neuroendocrine tumor (NET) burden. Given the higher SSTR affinity of [68 Ga] DOTATATE, we aimed to quantitatively investigate the biodistribution of [68 Ga]-labeled 1,4,7,10-tetraazacyclododecane-N,N',N″,N‴-tetraacetic acid-d-Phe(1)-Tyr(3)-octreotide ([68 Ga]DOTATOC) to determine a potential correlation between uptake in normal organs and NET burden...

PURPOSE: Somatostatin receptor antagonists have shown promise for imaging neuroendocrine tumors (NETs) in preclinical studies, but clinical data is still very limited. In this study, we assess the feasibility of using the novel somatostatin antagonist 68 Ga-DOTA-JR11 for PET imaging of NETs. METHODS: Twenty patients with advanced NETs underwent whole-body PET/CT imaging 60 min after injection of 169 MBq (median) 68 Ga-DOTA-JR11 as part of a prospective study. Volumes of interest were drawn around up to four 68 Ga-DOTA-JR11-avid lesions per patient (with uptake greater than liver) and standardized uptake values were estimated...

AIMS: Preventing kidney stone recurrence relies on detecting and modifying urine chemistry abnormalities. The assumption is that an abnormality is due to a global metabolic defect present in both kidneys. However, we hypothesize that clinically significant unilateral defects may exist. We aimed to identify these patients by sampling urine from each renal unit. MATERIALS AND METHODS: Adults undergoing retrograde upper urinary tract surgery were eligible for inclusion...

Background Obesity compromises cardiometabolic function and is associated with hypertension and chronic kidney disease. Exercise ameliorates these conditions, even without weight loss. Although the mechanisms of exercise's benefits remain unclear, augmented lean body mass is a suspected mechanism. Myostatin is a potent negative regulator of skeletal muscle mass that is upregulated in obesity and downregulated with exercise. The current study tested the hypothesis that deletion of myostatin would increase muscle mass and reduce blood pressure and kidney injury in obesity...

The calcium signalling and hedgehog (HH) signalling pathways operate in the primary cilium. Abnormalities in these pathways cause autosomal dominant polycystic kidney disease (ADPKD) and naevoid basal cell carcinoma syndrome (NBCCS) respectively. Several reports have proposed that hyperactivation of the HH pathway in animal models of polycystic kidney disease affects normal renal development and renal cyst phenotype. A family with 2 cases (a proband and her sister) of ADPKD and NBCCS coinheritance led us to investigate whether interactions may be present in the 2 pathways...

BACKGROUND: A recent study demonstrated that tolvaptan slowed estimated glomerular filtration rate (eGFR) decline in later-stage autosomal dominant polycystic kidney disease (ADPKD) patients. However, Japanese patients were not included in that trial, therefore tolvaptan's efficacy in Japanese patients with advanced chronic kidney disease (CKD) has remained unknown. METHODS: In this prospective cohort study, 54 patients with ADPKD who had eGFR ≥ 15 ml/min/1...

AIM: Indigenous Australians have an increased risk of developing Chronic Kidney Disease (CKD). Indigenous women have a higher rate of CKD than men. In a cohort of Indigenous and non-Indigenous preterm neonates, we assessed total renal volume (TRV) (a proxy indicator for nephron number). We hypothesised that there would be no difference in renal volume between these two groups at term corrected (37 weeks gestation). METHODS: Normally grown preterm neonates less than 32 weeks of gestation were recruited and at term corrected dates, the neonates underwent renal ultrasonography (TRV measurements), urine microalbumin-creatinine ratio (ACR) and serum analysis for Cystatin C measurement for eGFR calculation...

BACKGROUND: In a recent study we demonstrated that low birth weight (LBW) was associated with increased risk of progressive IgA nephropathy (IgAN). In the present study we investigate whether this could be explained by differences in glomerular morphological parameters. METHODS: The Medical Birth Registry of Norway has registered all births since 1967 and the Norwegian Kidney Biopsy Registry has registered all kidney biopsies since 1988. Patients diagnosed with IgAN, registered birth weight and estimated glomerular filtration rate above 60 ml/min/1...
