BACKGROUND: Maintenance hemodialysis (MHD) patients are often admitted to the hospital for severe morbidities. Prolonged intermittent renal replacement therapy (PIRRT) is required during the hospital staying. There are controversial opinions on the use of arteriovenous fistula (AVF) as vascular access for PIRRT in MHD patients. METHODS: Patients with AVF who accepted PIRRT in our center between January 2014 and June 2021 were retrospectively screened. AVF dysfunction and patient mortality were assessed as endpoints...

We sought to evaluate whether differences in left ventricular assist device (LVAD) canula alignment are associated with stroke. There is a paucity of clinical data on contribution of LVAD canulae alignment to strokes. We conducted a retrospective analysis of patients who underwent LVAD implantation at Houston Methodist hospital from 2011 to 2016 and included those who had undergone cardiac computed tomography (CT) with contrast. LVAD graft alignment using X-ray, echocardiography, and cardiac CT was evaluated...

Driveline infection is a frequent complication in recipients of durable left ventricular assist devices (LVAD), but its cause is largely unclear. Since vitamin D supplementation can reduce the risk of infections, we aimed at investigating the association of vitamin D deficiency with driveline infection. In 154 patients with continuous flow LVAD implants, we assessed 2-year risk of driveline infection according to vitamin D status (circulating 25-hydroxyvitamin D < 25 nmol/L or ⩾25 nmol/L). Of the study cohort, 34% ( n  = 53) had 25-hydroxyvitamin D concentrations <25 nmol/L...

A systematic review of the role of extracorporeal life support (ECLS) in pediatric patients with burn and smoke inhalation injury was undertaken. A systematic search of the literature according to a specific combination of keywords to ascertain the effectiveness of this treatment strategy was conducted. A total of 14 articles out of 266 were considered suitable for the analysis in pediatric patients. The PICOS approach and PRISMA flow chart were followed for the purpose of this review. Despite the limited number of studies on the subject, ECMO in burn and smoke inhalation injury provides an additional level of support in pediatric patients leading to positive outcomes...

BACKGROUNDS: Nitric oxide has a broad-spectrum antibacterial property promising as a new therapeutic agent for severe acute respiratory syndrome coronavirus-2 because nitric oxide donor (such as S-nitroso-N-acetylpenicillamine) reduces the replication of coronavirus-2. Patients with coronavirus disease 2019 undergoing dialysis generally have a higher mortality rate than the general population. Although the higher mortality rate in these patients may be related to their advanced age, it has been suggested that plasma nitrite and nitrate levels (products of nitric oxide metabolism) are significantly decreased after hemodialysis which may compromise the nitrate-nitrite-nitric oxide pathway and impair nitric oxide homeostasis...

RATIONALE: Current estimation of body fluid volumes in hemodialysis patients using bioimpedance analysis assumes constant specific electrical characteristics of biological tissues despite a large variation in plasma Na+ concentrations [Na+ ], ranging from 130 to 150 mmol/L. Here, we examined the potential effect of variable [Na+ ] on bioimpedance-derived volume overload. METHOD: Volumes were calculated from published whole-body extra- and intracellular resistance data and relationships using either "standard" or "revised" specific electrical characteristics modeled as functions of [Na+ ]...

Acute respiratory distress syndrome (ARDS) can develop early in burn patients with inhalation injury in the presence of cytokine storm and the proinflammatory response can be a supplemental factor for ARDS aggravation. We report the case of a 41-years old male with 25% total body surface area deep partial thickness burns to upper body extremity and grade II inhalational injury who developed severe ARDS, nosocomial pneumonia, and septic shock. Veno-venous extracorporeal membrane oxygenation (VV ECMO) and continuous renal replacement therapy (CRRT) with hemoadsorption were successfully used at different moments to overcome critical situations...

A person becomes disabled when they lose any of their sensory organs, the eye being one of the most delicate. Loss of an eye can happen due to different reasons and can be restored using different materials and strategies. Ocular defects and congenital deformations show up as a result of tumors or injury. For the most part, fabricated eyes are accessible as ocular prostheses. This method describes how to create a custom ocular prosthesis using a digital photo and UV printing. The greatest esthetically pleasing results are also achieved using this production method, which does not necessitate painting or color-selecting expertise...
