Today, central venous access catheters play an important role in the treatment and management of many dialysis patients. Their use and care may influence the patient's overall outcome. Therefore, it is critical to have a thorough knowledge of the vascular anatomy, types of catheters, placement techniques and maintenance and management of complications. The incidence nowadays of acute renal failure in intensive care patients is reported as high as 25%. Acute renal failure is one of the few causes of organ failure in which complete recovery is possible, provided the patient survives the associated comorbid conditions. There are various extracorporeal dialysis techniques available to treat this category of patients using mostly a central dialysis catheter as vascular access. It is important to select carefully the type of catheter and to create a specific vascular access system in order to be able to perform the selected dialysis technique in the most optimal efficient conditions. Any inadequacies of access will create dialysis insufficiency leading to more comorbid conditions and even higher mortality. In this article, we will describe the different possibilities as well as the nursing management of that type of vascular access in patients with acute renal failure.

Childhood obesity is a growing global concern due to its long-term health consequences. Yet, more research relying on multiple time-point BMI measurements is warranted to gain further insight into obesity's temporal trends. We aimed to identify BMI trajectories in children aged 2-10 years and evaluate their association with sociodemographic factors.

Totally implantable central venous catheters (CVCs) are widely used in the management of patients with malignant diseases. Conventionally, port implantations were carried out by general surgeons and vascular radiologists. In recent years, the medical staff of the Medical Oncology department at the Central University Hospital of Asturias (HUCA) has developed a simplified methodology for the routine implantation of these devices.

Access to trained lymphedema care providers remains limited making patient-driven management solutions essential. One such option, sequential intermittent pneumatic compression (IPC), has gained traction as a supportive tool for lymphedema management. While newer IPC devices and innovative applications are being introduced to the market, questions regarding the safety and efficacy of this technology persist.

A healthy diet is a key determinant of successful aging. However, the psychological, social, and physiological changes associated with ageing often disrupt dietary behaviours. Hungary has one of the highest rates of chronic age-related diseases in the European Union, exacerbated by unhealthy dietary patterns and rapid population aging.

Purpose: We present the case of a rare extrahepatic portocaval shunt that resulted in communication of the portal vein and the inferior vena cava (IVC) at the level between two right renal veins that was incidentally diagnosed with contrast-enhanced computed tomography (CECT) in an asymptomatic patient.
Methods: A woman in her sixties with abdominal pain and diarrhea of unclear origin underwent exploratory abdominal CECT.
Results: The CECT incidentally revealed an extrahepatic portocaval shunt, whereby a vessel arising from the portal vein superior to the confluence of the superior mesenteric and splenic veins drained into the posterior aspect of the IVC between two right renal veins.
