Physical Exercise of Patients on Hemodialysis, Optimistic or Pessimistic.

Chronic kidney disease leads to significant functional limitations and severe disability, which requires the application of an appropriate physical rehabilitation strategy that helps patients achieve social well-being and significant health benefits.

Influence of Different β-Blockers on Platelet Aggregation in Patients With Coronary Artery Disease on Dual Antiplatelet Therapy.

Introduction: The use of β-blockers in the treatment of patients with coronary heart disease is associated with a decrease in the frequency of angina pectoris and mortality of patients. Due to the severity of the disease and previous cardiovascular interventions, many patients with coronary artery disease (CAD) use dual antiplatelet therapy to achieve greater inhibition of platelet aggregation. The influence of β-blockers on platelet aggregation in patients using antiplatelet therapy is not well understood.

The reliability of body mass index in the diagnosis of obesity and metabolic risk in children.

Background: Body mass index (BMI) is the most widespread and the simplest method for the evaluation of body mass; it is often used as a sole technique in the diagnosis of obesity in children. The objective of the study was to evaluate the relationship between anthropometric and biochemical parameters and the incidence of the metabolic syndrome in obese children.

Methodology: A total of 110 children, aged 2-17 years, participated in the study.

Stroke and diabetic ketoacidosis--some diagnostic and therapeutic considerations.

Cerebrovascular insult (CVI) is a known and important risk factor for the development of diabetic ketoacidosis (DKA); still, it seems that the prevalence of DKA among the patients suffering CVI and its influence on stroke outcome might be underestimated. Diabetic ketoacidosis itself has been reported to be a risk factor for the occurrence of stroke in children and youth. A cerebral hypoperfusion in untreated DKA may lead to cerebral injury, arterial ischemic stroke, cerebral venous thrombosis, and hemorrhagic stroke.

Geriatric nutritional risk index (GNRI) ≤ 90 could be linked with malnutrition-inflammation complex syndrome. This study measured XOD, myeloperoxidase (MPO), superoxide dismutase (SOD), lipid hydroperoxides, total free thiol groups, and advanced oxidation protein products (AOPP) in 50 HD patients before commencing (pre-HD) and immediately after completion of HD session (post-HD) and in 22 healthy controls.

Nasal septum extramedullary plasmacytoma.

Introduction: Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate in either bone--solitary osseous plasmacytoma, or in soft tissue--extramedullary plasmacytoma (EMP). EMP represents less than 1% of all head and neck malignancies.

Most important chronic complications of arteriovenous fistulas for hemodialysis.

The aim of this review was to highlight the most important complications of arteriovenous fistulas (AVFs) for hemodialysis (HD). The quality of vascular access for HD should be suitable for repeated puncture and allow a high blood flow rate for high-efficiency dialysis with minimal complications. The dialysis staff must be well versed in manipulation of the AVF, and there should be a minimal need for corrective interventions.
