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...

BACKGROUND: Sepsis could affect the outcomes of patients with postcardiotomy cardiogenic shock supported with extracorporeal membrane oxygenation (ECMO). Our objectives were to characterize sepsis patients with ECMO support for postcardiotomy cardiogenic shock and assess its predictors and effect on patients' outcomes. METHODS: This retrospective study included 103 patients with ECMO for postcardiotomy cardiogenic shock from 2009 to 2020.

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...

OBJECTIVE: Assessment of the results of the ProtekDuo cannula applied for dedicated right ventricular support with oxygenator in ARDS secondary to COVID-19. METHODS: Systematic literature search in NHS library, Medline (Pubmed) and EMBASE using appropriate keywords as well as PICOS and PRISMA approach. RESULTS: Out of 285 publications found, 5 publications met the search criteria and were included in this review. A total of 194 patients with ARDS secondary to COVID-19 underwent ProtekDuo placement to establish a combination of respiratory [veno-venous extracorporeal membrane oxygenation (V-V ECMO)] and right ventricular support...

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...

PURPOSE: This study aimed to observe the effect of basic fibroblast growth factor (bFGF) gel preparation on wound repair in a full-thickness skin defect rat model and to further explore its mechanism. METHODS: The full-thickness skin defect model of Wistar rats was created with circular wounds of 20 mm or 10 mm in diameter on both sides of the spine. The animals were divided into the normal, model, control gel, and bFGF gel groups (300 IU/cm2 )...

BACKGROUND: Acute liver failure (ALF) is a severe liver disease with high morbidity and mortality rates. Animal models are important for research on ALF. This study aimed to establish a reproducible, Tibetan miniature pig model of D-galactosamine-induced ALF and verify it using a dual plasma molecular adsorption system (DPMAS). METHODS: Tibet miniature pigs were randomly divided into four groups (A, B, C, D) after catheterization. D-galactosamine (D-gal) at 0.45, 0...

The use of dabigatran in patients with non-valvular atrial fibrillation (AF) has widely increased in the last decades, due to its positive effects in terms of safety/efficacy. However, because of the risk of major bleeding, a great degree of attention has been suggested in elderly patients with multiple comorbidities. Notably, dabigatran mainly undergoes renal elimination and dose adjustment is recommended in patients with Chronic Kidney Disease (CKD). In this regard, the onset of an abrupt decrease of kidney function may further affect dabigatran pharmacokinetic profile, increasing the risk of acute intoxication...

OBJECTIVE: To evaluate the association between brachial artery blood velocity by color Doppler flow imaging (CDFI) and primary maturation of radio-cephalic autologous arteriovenous fistula (RC-AVF). METHODS: Clinical data from patients who underwent end-to-side cephalic-radial anastomosis were collected from December 2015 to December 2020. The anastomosis diameter (mm), blood velocity (cm/s), and brachial artery diameters (mm) 7 cm proximal to the elbow pre- and postoperation were measured by GE LOGIC-E9 ultrasound...

AIMS: An intradialytic cramp, which frequently occurs in hemodialysis patients, is a disturbing condition. This study was conducted to evaluate the effect of local cold applications on the severity and duration of intradialytic cramps in patients with chronic kidney disease. MATERIALS AND METHODS: This quasi-experimental study sample comprised of 74 patients who were aged >18 years, conscious, and reported experiencing intradialytic cramps in a dialysis center...

Acute and acute-on-chronic liver failure is a cause of death in patients suffering from viral hepatitis, and many cases need liver transplantation. Infection from hepatitis B virus may range from asymptomatic to severe acute and fulminant hepatitis. In this setting, treatment is mainly supportive as there is no consensus on antiviral therapy based on non-nucleoside reverse transcriptase inhibitors. Single-pass albumin dialysis is a liver-support technique for patients suffering from liver failure, that has shown effectiveness in the removal of both water-soluble and albumin-bound toxins, which accumulate due to impairment of the liver's cleansing function...
