BACKGROUND: Hypertension is prevalent in chronic kidney disease (CKD), but the control of hypertension is suboptimal. We reported the prevalence and characteristics of resistant and undertreated hypertension based on a nationwide survey aiming to improve blood pressure (BP) control. METHODS: Resistant hypertension (RH) was defined as BP above the target (<140/90 mm Hg) despite the use of 3 antihypertensive drugs or achieving the target BP by using ≥4 antihypertensive drugs...

Portable, on-site blood typing methods will help provide life-saving blood transfusions to patients during an emergency or natural calamity, such as significant earthquakes. We have previously developed waveguide-mode (WM) sensors for forward ABO and Rh(D) blood typing and detection of antibodies against hepatitis B virus and hepatitis C virus. In this study, we evaluated a WM-sensor for reverse ABO blood typing. Since reverse ABO blood typing is a method for detection of antibodies against type A and type B oligosaccharide antigens on the surface of red blood cells (RBCs), we fixed a synthetic type A or type B trisaccharide antigen on the sensor chip of the WM sensor...

BACKGROUND: The Rh blood group system is the most polymorphic system and is implicated in hemolytic transfusion reaction and hemolytic disease of the fetus and newborn. Molecular genetics of the RH genes have been extensively studied in Caucasians, Africans, and East Asians and the variant alleles giving rise to weak and partial D phenotypes have been reported. However, limited genetic studies have been carried out in the large Indian population, even though the variability of Rh expression has been documented...

The ABO and rhesus (Rh) blood group antigens are the most frequently studied genetic markers in a large group of people. Blood type frequencies vary in different racial/ethnic groups. Our objective was to investigate the distribution of the ABO and rhesus (Rh) blood groups by molecular typing method in a population of Saudi stem cell donors. Our data indicate that the most common blood group in our population is group O followed by group A then group B, and finally, the least common is group AB.

BACKGROUND: Resistant hypertension is characterized when the blood pressure (BP) remains above the recommended goal after taking three antihypertensive drugs with synergistic actions at their maximum recommended tolerated doses, preferably including a diuretic. Identifying the contribution of intravascular volume and serum renin in maintaining BP levels could help tailor more effective hypertension treatment, whether acting on the control of intravascular volume or sodium balance, or acting on the effects of the renin-angiotensin-aldosterone system (RAAS) on the kidney...

Minorhepatectomy (MH) is a common type of robotic-assisted liver resection, but few studies compared it with laparoscopic. We compared the perioperative outcomes of patients who underwent robotic (RH) or laparoscopic (LH) minor hepatectomy and evaluated the effect of surgeon's experience on outcomes. A prospective database was used to identify patients from 2009 through 2016 who underwent RH or LH. Two surgeons performed RH starting in 2014, whereas LH had been established before that. Of the 93 patients, 42 were in RH and 51 in LH group...

Dithiothreitol (DTT), a reducing reagent, has multiple applications in blood bank testing. DTT disrupts the bridging of the disulfide bonds between amino acid residues necessary for structural conformation of some proteins and the bonds holding an IgM molecule in the pentameric formation. DTT treatment of red blood cells (RBCs) can denature or modify certain blood group antigens-in particular, those in the Kell, Lutheran, YT, JMH, LW, Cromer, Indian, Dombrock, and Knops systems-and prevent recognition by the corresponding antibodies...

Bone marrow concentrate (BMC), which is enriched in mononuclear cells (MNCs) and platelets, has recently attracted the attention of clinicians as a new optional means for bone engineering. We previously reported that the osteoinductive effect of bone morphogenetic protein-2 (BMP-2) could be enhanced synergistically by co-transplantation of peripheral blood (PB)-derived platelet-rich plasma (PRP). This study aims to investigate whether BMC can effectively promote bone formation induced by low-dose BMP-2, thereby reducing the undesirable side-effects of BMP-2, compared to PRP...

Hypertension is associated with microcirculatory impairment. Our objectives were to evaluate endothelial function and inflammatory biomarkers in patients with resistant (RH) and mild to moderate (MMH) arterial hypertension in comparison to normotensives (control group-CG). Three groups, 25 patients each, have been investigated, by anamnesis, venous occlusion plethysmography (VOP) and serum determination of adhesion molecules (VCAM, ICAM), adiponectin, endothelin and C-reactive protein (CRP). Patients not using statins and with or without blood pressure control were also analyzed...
