The hematocrit (Hct) determines the oxygen carrying capacity of blood, but also increases blood viscosity and thus flow resistance. From this dual role the concept of an optimum Hct for tissue oxygenation has been derived. Viscometric studies using the ratio Hct/blood viscosity at high shear rate showed an optimum Hct of 50-60% for red blood cell (RBC) suspensions in plasma. For the perfusion of an artificial microvascular network with 5-70μm channels the optimum Hct was 60-70% for high driving pressures. With lower shear rates or driving pressures the optimum Hct shifted towards lower values...

Dulaglutide (DU) is a once-weekly glucagon-like peptide-1 receptor agonist approved for treatment of type 2 diabetes. Integrated data from 9 phase 2 and 3 trials in type 2 diabetes (N = 6005) were used to evaluate effects of DU on estimated glomerular filtration rate (eGFR, mL/min/1.73m(2) [Chronic Kidney Disease Epidemiology Collaboration]), urine albumin-to-creatinine ratio (UACR, mg/g), and kidney adverse events. No significant differences in eGFR were observed during treatment for DU versus placebo (PL), active comparators (AC), or insulin glargine (IG) (mean±SD; DU: 87...

Aristolochic acid nephropathy (AAN) is a progressive kidney disease caused by a Chinese herb containing aristolochic acid. Excessive death of renal tubular epithelial cells (RTECs) characterized the acute phase of AAN. Therapies for acute AAN were limited, such as steroids and angiotensin-receptor blockers (ARBs)/angiotensin-converting enzyme inhibitors (ACEIs). It was interesting that, in acute AAN, female patients showed relative slower progression to renal failure than males. In a previous study, female hormone 17β-estradiol (E2) was found to attenuate renal ischemia-reperfusion injury...

Acute kidney injury (AKI) is associated with high perioperative mortality. A series of AKI research breakthroughs are worth mentioning. First, in 2003, serum and urine biomarkers specific to AKI were identified. These biomarkers have contributed to early detection, prevention, and treatment of AKI. In 2004, AKI severity was defined with the Risk, Injury, Failure, Loss, and End-stage kidney disease (RIFLE) criteria, which was developed by the International Consensus Conference Workgroup of the Acute Dialysis Quality Initiative...

BACKGROUND: Current vancomycin dosing guidelines recommend targeting trough concentrations of 15-20 mg/L in complicated infections to avoid treatment failure and resistance. How to accomplish this in the intermittent hemodialysis (IHD) population has not been adequately described. A weight-based vancomycin dosing protocol for IHD patients was developed to provide standardization of vancomycin dosing for this patient population. Prior to implementation of this protocol, clinical pharmacists used their individual judgment for dosing and monitoring...

OBJECTIVE: In most cases, the 5 first line drugs are recommended for management of hypertension without preference for one or the other. However, it is unclear whether different classes of anti-hypertensive agents have different effect on survival in low risk, uncomplicated hypertension. The aim of this study was to evaluate effects of 4 classes of first line anti-hypertensive agents on improving survival in patients with low risk, uncomplicated hypertension. DESIGN AND METHOD: Adult hypertensive patients without chronic kidney disease, end stage renal disease, diabetes mellitus, acute coronary syndrome, and heart failure in 2002 were selected from Korean National Health Insurance sample cohort consisting of one million subjects...

BACKGROUND: Choice of the optimal target for blood pressure (BP) reduction during treatment of patients with hypertension, including those with underlying co-morbid conditions, is an important challenge in clinical practice. The Systolic Blood Pressure Intervention Trial (SPRINT) was designed to provide guidance in selection of a Systolic BP target during treatment of hypertension. METHODS: Adults ≥50 years old with hypertension and at least one additional risk factor for cardiovascular disease (CVD), but excluding persons with diabetes mellitus, prior stroke, or advanced chronic kidney disease (CKD) were randomly assigned to intensive therapy (intensive), targeting a systolic BP (SBP) <120 mmHg, or standard therapy (standard), targeting a SBP <140 mmHg...

According to the seventh report of Joint National Committee (JNC 7), hypertensive emergency (HE), a kind of hypertensive crisis, is defined as a sudden and abrupt elevation in blood pressure so as to cause acute target organ dysfunctions, including central nervous system, cardiovascular system or kidneys. Patients with HE require immediate reduction in markedly elevated blood pressure. Currently, there are no international guidelines for children HE, so the JNC definition is commonly used. Hypertensive emergency in children is rare but a life-threatening emergency...

Hypertension is the most common risk factor for systolic and diastolic heart failure. Based on population-attributable risks, hypertension has the greatest impact on the development of heart failure, accounting for 39% of HF events in men and 59% in women. Higher blood pressure, longer duration of hypertension and older age are associated with higher incidence of heart failure however, long term control of hypertension reduces the risk of heart failure. Thus current guideline pointed the hypertension as the single most important modifiable risk factor for heart failure...

Tissue transglutaminase 2 enzyme plays a diverse role in intracellular and extracellular functioning. Aberrant expression of anti-TG2 antibody has recently been proposed for extraintestinal identification of celiac disease (CeD), but its utility is questionable. To examine whether anti-TG2 immunohistochemical (IHC) staining can be of diagnostic value in identifying extraintestinal involvement in CeD, tissue blocks of patients with IgA nephropathies (IgAN), minimal change disease, membranous glomerulonephritis, membrano-proliferative glomerulonephritis, normal kidney, intestinal biopsies from CeD, tropical sprue, nonspecific duodenitis, and inflammatory bowel disease; liver biopsies from patients with chronic hepatitis B and C, acute liver failure (ALF), and CeD-associated liver diseases were retrieved and subjected to IHC staining for anti-tissue transglutaminase 2 enzyme...

BACKGROUND: Cytomegalovirus (CMV) has a role in chronic rejection and graft loss in kidney transplant (KTx) and lung transplant (LTx) recipients. In addition, donor CMV seropositivity is an independent risk factor for renal graft loss. The anti-CMV response might modulate this risk. Expression of programmed cell death 1 (PD-1), a receptor involved in viral-specific T-cell exhaustion, is influenced by a single nucleotide polymorphism called PD-1.3 (wild-type allele G, variant allele A)...
