Hemodialysis water reuse within a circular economy approach. What can we add to current knowledge? A point of view.

The ongoing climate change and the ecological challenges call for sustainable medicine and, in our field, sustainable kidney care. Dialysis is life-saving and resource-consuming, and high water consumption is one of the main concerns. Circular water economy, meaning reuse and recycling of water, and recovering resources can help reducing emissions and enhancing resilience to climate change.

Nitrogen and phosphorus recovery from hemodialysis wastewater to use as an agricultural fertilizer.

Introduction: Hemodialysis wastewater contains high concentrations of ammonia nitrogen and phosphorus. Recovery of these nutrients as soil fertilizers represents an interesting opportunity to ensure a sustainable fertilizer supply.

Methods: In this paper, a simple method for recovering phosphorous and nitrogen as crystalline struvite [MgNHPO·6HO] is presented.

Towards zero liquid discharge in hemodialysis. Possible issues.

Scarcity of water and energy, and legal requirements for discharge of waste and wastewater are forcing hemodialysis facilities to change their approach to a more integrated concept of connecting the residual output (in terms of waste, wastewater and energy loss) to the input (in terms of water and energy). Zero liquid discharge is an expanding water treatment philosophy in which hemodialysis wastewater is purified and recycled, leaving little to no effluent remaining when the process is complete, thereby saving money and being beneficial to the environment. This article explores the possible ways to treat hemodialysis wastewater, thus achieving ZLD conditions.

The effects of water shortages on health and human development.

Shortages of water could become a major obstacle to public health and development. Currently, the United Nations Children's Fund (UNICEF) and the World Health Organization (WHO) estimate that 1.1 billion people lack access to a water supply and 2.

Water conservation: an emerging but vital issue in hemodialysis therapy.

Water conservation refers to reducing the usage of water and recycling of wastewater for different purposes such as irrigation, laundry and sanitation. As water scarcity increases worldwide, dialysis facilities should be focused on salvaging water. However, most of them still ignorantly discard to the sewer huge volumes of this reusable resource.

Current understanding of ozone use for disinfecting hemodialysis water treatment systems.

Background: Water treatment systems are susceptible to microbial contaminations and periodical disinfection procedures are mandatory to obtain results requested from international standards. According to the Association for the Advancement of Medical Instrumentation, ozone is the most effective method to destroy microorganisms, and to prevent, reduce or remove the biofilm. This study aims to review the literature on the application of ozone in the disinfection of water treatment systems for hemodialysis.

Severe jaw enlargement associated with uremic hyperparathyroidism.

Marked enlargement of the jaws is a rare complication of renal osteodystrophy. This report describes a localized enlargement of the mandible due to a brown tumor in a patient undergoing chronic hemodialysis. Literature on jaw involvement in secondary hyperparathyroidism is reviewed.

Recycling wastewater after hemodialysis: an environmental analysis for alternative water sources in arid regions.

Water is a vital aspect of hemodialysis. During the procedure, large volumes of water are used to prepare dialysate and clean and reprocess machines. This report evaluates the technical and economic feasibility of recycling hemodialysis wastewater for irrigation uses, such as watering gardens and landscape plantings.

End-stage renal disease following carboplatin chemotherapy for a nasopharyngeal carcinoma.

Renal failure secondary to carboplatin therapy is due to acute tubular necrosis and is usually reversible. However, acute renal failure with rapid progression to end-stage renal disease is an exceedingly rare complication of carboplatin therapy. The authors report a case of definitive renal failure secondary to carboplatin chemotherapy for a nasopharyngeal carcinoma.

Optimizing hypertension control in hemodialysis patients: a proposed management strategy.

Objective: The purpose of the study was to assess the efficiency of a goal-oriented therapeutic strategy in lowering blood pressure and reducing the need for antihypertensive medications in 168 patients undergoing long-term hemodialysis.

Methods: Patients were managed initially by achieving optimal dry weight. After reduction of the dry weight, patients with uncontrolled arterial hypertension were dialyzed using a 1.
