A 59-year-old man presented to the emergency department with a chief complaint of sore throat after swallowing sodium picosulfate/magnesium citrate powder for bowel preparation, without first dissolving it in water. The initial evaluation showed significant mucosal injury involving the oral cavity, pharynx, and epiglottis. Endotracheal intubation was performed for airway protection in the emergency department, because the mucosal swelling resulted in upper airway compromise. After conservative treatment in the intensive care unit, he underwent tracheostomy because stenosis of the supraglottic and subglottic areas was not relieved...

Sodium picosulfate/magnesium citrate (SPMC) is a widely used oral bowel cleansing agent considered to be relatively safe. However, partially dissolved or undissolved SPMC powder may cause severe injuries of the esophagus and stomach. We report a very rare case of acute gastric injury without esophageal damage caused by the ingestion of undissolved SPMC powder. A 69-year-old man experienced epigastric pain after swallowing SPMC powder without dissolving it in water in preparation for a screening colonoscopy...

INTRODUCTION: Shared medical appointments (SMAs) have decreased patients' wait time to initial stone clinic appointment, standardized education, and increased exposure to nutrition therapy. We assessed the effectiveness of SMAs in reducing patients' urinary stone risk factors. METHODS: Patients who established care in our stone clinic in a SMA between 3/2012 and 8/2015 were sequentially identified. After eliminating those without follow-up urine collections or whose urinary creatinine excretion between the 2 collections varied by >40%, 113 patients were included (M:F 63:50; 54±15 y; BMI 30...

BACKGROUND: Use of the Freedom SOLO (FS) stentless aortic bioprosthesis is limited by a unique and as yet unexplained severe decrease in postoperative platelet count in the absence of FS-related excess bleeding or thromboembolism. We investigated whether anticoagulant-associated pseudothrombocytopaenia could explain this complication. METHODS: Thirty consecutive patients (mean age 75.4±7.7 years, 11 [36.7%] female) underwent elective aortic valve replacement (AVR) with either the stented bovine Mitroflow (MF, n=18) or the stentless bovine FS (n=12) aortic valve bioprostheses...

BACKGROUND AND AIM: Today, voluntary donation of peripheral blood stem cells by healthy donors for allogeneic hemopoietic cell transplantation is common worldwide. Such donations are associated with small but measurable risks of morbidity and mortality. Most complications are associated with citrate infusion during cell collection. We studied the effects of citrate infusion on the QTc and other vital parameters during and after peripheral stem cell apheresis in volunteers. METHOD: To ensure that donors were healthy, screening included taking a detailed medical history, physical examination, and laboratory measurements of plasma calcium and magnesium...

In this study a natural culture medium that mimics the synthetic yeast peptone glucose medium used for yeast fermentations was designed to screen and select yeasts capable of producing high levels of diacetyl and acetaldehyde. The presence of whey powder and sodium citrate in the medium along with manganese and magnesium sulfate enhanced both biomass and aroma development. A total of 52 yeasts strains were cultivated in two different culture media, namely, yeast peptone glucose medium and yeast acetaldehyde-diacetyl medium...

Yarrowia lipolytica cultivated under double nitrogen and magnesium limitation, but not under single nitrogen or single magnesium limitation, produced 12.2g/l biomass containing 47.5% lipids, which corresponds to a lipid production 5.8g/l. These yields are the higher described in the literature for wild strains of Y. lipolytica. Transcription of ACL1 and ACL2, encoding for ATP-citrate lyase (ATP:CL) was observed even under non-oleaginous conditions but high activity of ATP:CL was only detected under oleaginous conditions induced by low or zero activity of NAD(+) dependent isocitrate dehydrogenase...

Succinyl-CoA synthetase catalyzes the only step in the citric acid cycle that provides substrate-level phosphorylation. Although the binding sites for the substrates CoA, phosphate, and the nucleotides ADP and ATP or GDP and GTP have been identified, the binding site for succinate has not. To determine this binding site, pig GTP-specific succinyl-CoA synthetase was crystallized in the presence of succinate, magnesium ions and CoA, and the structure of the complex was determined by X-ray crystallography to 2...

Diet rich in fruits, vegetables, and dairy products, known as the Dietary Approaches to Stop Hypertension (DASH) diet, is known to reduce blood pressure (BP) in hypertensive patients. More recently, the DASH diet was shown to reduce oxidative stress in hypertensive and nonhypertensive humans. However, the main nutritional components responsible for these beneficial effects of the DASH diet remain unknown. Because the DASH diet is rich in potassium (K), magnesium (Mg), and alkali, we performed a randomized, double-blinded, placebo-controlled study to compare effects of potassium magnesium citrate (KMgCit), potassium chloride (KCl), and potassium citrate (KCit) to allow dissociation of the three components of K, Mg, and citrate on 24-hour ambulatory BP and urinary 8-isoprostane in hypertensive and prehypertensive subjects, using a randomized crossover design...

BACKGROUND: The requirements for magnesium (Mg) supplementation increase under regional citrate anticoagulation (RCA) because citrate acts by chelation of bivalent cations within the blood circuit. The level of magnesium in commercially available fluids for continuous renal replacement therapy (CRRT) may not be sufficient to prevent hypomagnesemia. METHODS: Patients (n = 45) on CRRT (2,000 ml/h, blood flow (Qb) 100 ml/min) with RCA modality (4% trisodium citrate) using calcium free fluid with 0...

OBJECTIVES: There are conflicting reports on the reliable measurement of platelet count and mean platelet volume (MPV) using EDTA or citrate. The anticoagulant properties of magnesium sulfate (MgSO4) are known from the literature. The aim of this study was to evaluate MgSO4 as an in vitro anticoagulant for platelet count, MPV, platelet distribution width, and platelet activation. METHODS: Whole blood from volunteers was anticoagulated by EDTA, citrate, or MgSO4 Platelets were counted by the XE 5000 (Sysmex, Norderstedt, Germany) impedance and fluorescence optical technique...
