INTRODUCTION: Nasal irrigation solutions are widely used following endonasal surgery. These irrigation solutions remove infective debris and crusts, reducing the probability of synechia formation, and accelerate mucosal healing. OBJECTIVE: The aim of the present study was to compare the effects of nasal irrigation solutions with different contents following septoplasty and concha radiofrequency. METHODS: The present study was a prospective, randomized, controlled simple blind study of 120 patients who underwent septoplasty and bilateral concha radiofrequency...

Learning accurate probabilistic models from data is crucial in many practical tasks in data mining. In this paper we present a new non-parametric calibration method called ensemble of near isotonic regression (ENIR). The method can be considered as an extension of BBQ [20], a recently proposed calibration method, as well as the commonly used calibration method based on isotonic regression (IsoRegC) [27]. ENIR is designed to address the key limitation of IsoRegC which is the monotonicity assumption of the predictions...

BACKGROUND: After defibrillation of initial ventricular fibrillation (VF), it is crucial to prevent refibrillation to ensure successful resuscitation outcomes. Inability of the late Na(+) current to inactivate leads to intracellular Ca(2+) dysregulation and arrhythmias. Our aim was to determine the effects of ranolazine and GS-967, inhibitors of the late Na(+) current, on ventricular refibrillation. METHODS AND RESULTS: Long-duration VF was induced electrically in Langendorff-perfused rabbit hearts (n=22) and terminated with a defibrillator after 6 minutes...

BACKGROUND: Saline, the intravenous fluid most commonly administered to critically ill adults, contains a high chloride content, which may be associated with acute kidney injury and death. Whether using balanced crystalloids rather than saline decreases the risk of acute kidney injury and death among critically ill adults remains unknown. METHODS: The Isotonic Solutions and Major Adverse Renal Events Trial (SMART) is a pragmatic, cluster-level allocation, cluster-level crossover trial being conducted between 1 June 2015 and 30 April 2017 in five intensive care units at Vanderbilt University Medical Center in Nashville, TN, USA...

Cisplatin, a first-generation platinum derivative, is one of the most widely used anticancer agents and can treat a broad spectrum of malignancies. Cisplatin-induced nephrotoxicity is a major dose-limiting side effect resulting from damage to the proximal tubules of the kidney. This nephrotoxicity can be prevented by lowering the concentration of cisplatin and shortening the period of cisplatin exposure to the proximal tubules. In clinical practice, high-volume hydration(>3 L intravenous isotonic saline), forced diuresis(mannitol and/or furosemide), and magnesium supplementation have been generally used to lower the risk of cisplatin-induced nephrotoxicity...

Fluorescent calcium indicators are a popular means for observing the spiking activity of large neuronal populations, but extracting the activity of each neuron from raw fluorescence calcium imaging data is a nontrivial problem. We present a fast online active set method to solve this sparse non-negative deconvolution problem. Importantly, the algorithm progresses through each time series sequentially from beginning to end, thus enabling real-time online estimation of neural activity during the imaging session...

BACKGROUND: Inhibition of procoagulant pathways may improve outcome in sepsis. We examined whether a dual short-acting thrombin (factor II) and factor X (FX)a inhibitor (SATI) ameliorates sepsis-induced disseminated intravascular coagulation (DIC) and is organ-protective. METHODS: Escherichia coli were infused for 2 h in 22 anesthetized baboons. The control (CO) group (n = 8) received sterile isotonic solution only. In the treatment groups, SATI was administered starting 15 minutes after the end of the bacterial exposure...

BACKGROUND: Subarachnoid hemorrhage (SAH) can lead to neurogenic pulmonary edema (NPE), and chylomicron metabolism may be altered unfavorably in acute lung injury. This study aimed to investigate the possible effect of NPE on the development of coronary fat embolism. METHODS: This study was conducted on 27 rabbits, 5 of which were used as the control (n=5). Experimental SAH was induced in 15 of the animals by injecting homologous blood into the cisterna magna, and the remaining 7 animals were administered only isotonic saline solution (Sham, n=7) in the same manner under general anesthesia...

Martin D Hoffman, Jeremy Joslin, Ian R Rogers
Dehydration and exercise-associated hyponatremia (EAH) are both relatively common conditions during wilderness endurance events. Whereas dehydration is treated with fluids, EAH is appropriately managed with fluid restriction and a sodium bolus but can worsen with isotonic or hypotonic fluids. Therefore, caution is recommended in the provision of postevent rehydration in environments where EAH is a potential consideration because accurate field assessment of hydration status can be challenging, and measurement of blood sodium concentration is rarely possible in the wilderness...

Increases in plasma osmolality activates the paraventricular nucleus of the hypothalamus (PVN) which in turn mounts a physiological response by increasing the release of arginine vasopressin and sympathetic nerve activity to end organs such as the kidney. The PVN expresses an abundance of purinergic receptors including P2X2 receptors. In the present study, we sought to determine 1) whether P2X2-expressing PVN neurons are activated by hypertonic saline or hypertonic mannitol and 2) what effects P2X receptor blockade has on sympathetic nerve activation mediated by a hyperosmotic stimulus...

The administration of intravenous fluids remains a common intervention for hospitalised children. Commonly used hypotonic fluids administered at maintenance rates provide 2-4 mmol/kg/day of sodium. Being hypotonic, the development of hyponatraemia remains a risk. The consequences of hyponatraemia are not insignificant, with possibilities of irreversible neurological morbidity and mortality. There is currently no clear consensus on the optimal composition of fluids to be used for intravenous rehydration. A review of the available literature suggests that children who receive isotonic fluid have a lower risk of developing hyponatraemia, regardless of the rate of administration...
