SELF CALIBRATING BLOOD CHAMBER

Номер: CA0002935203A1
Принадлежит:

An optical blood monitoring system and corresponding method avoid the need to obtain a precise intensity value of the light impinging upon the measured blood layer during the analysis. The system is operated to determine at least two optical measurements through blood layers of different thickness but otherwise substantially identical systems. Due to the equivalence of the systems, the two measurements can be compared so that the bulk extinction coefficient of the blood can be calculated based only on the known blood layer thicknesses and the two measurements. Reliable measurements of various blood parameters can thereby be determined without certain calibration steps.

HIGH CITRATE DIALYSATE AND USES THEREOF

Номер: US20150083664A1
Принадлежит:

The dose of dialysis in terms of urea clearance is marginal in many hemodialysis patients, and metabolic acidosis as determined by the pre-dialysis serum HCOlevel is common. A dialysate that included citric acid rather than acetic acid as acidifying agent provides superior performance properties. Citrate-containing dialysate was used exclusively in 22 hemodialysis patients. Initially, only 8 of the 22 patients had a pre-dialysis serum HCO>23 mEq/L (lower limit of normal), however, after 12 weeks of dialysis using the citrate-containing dialysate, the serum HCOnormalized in 15 patients (p=0.0001, Chi-square). Dialysis variables were kept constant in 19 of the patients, who also used and reused the same dialyzer model throughout. In these patients, the initial average urea reduction ratio (URR) was 68.5±5.9%, and after treatment with the citrate dialysate disclosed herein, this ratio had increased to 73±5.3% (p<0.03). SpKt/V, calculated using the Daugirdas II formula, also increased from 1.23±0.19 to 1.34±0.2 (p=0.01). This increased urea clearance may be the result of the anticoagulant property of citrate maintaining patency of the dialyzer membrane. The increase in pre-dialysis serum HCOmay represent increased delivery from the dialysate and production from citric acid. 131-. (canceled)32. A method of performing dialysis on a patient in need thereof , wherein the method comprises:a) performing the dialysis wherein the patient is heparin-free during the time of dialysis; andb) performing the dialysis in a dialyzer with a dialysate composition comprising citrate at a concentration ranging from 2.4 to 20 mEq/L, calcium at a concentration ranging from 2.5 to 5 mEq/L and magnesium at a concentration ranging from 0.75 to 2 mEq/L, wherein the patient has an intolerance to heparin, an antibody to heparin, a risk of bleeding from the use of direct administration of heparin or chronic acidosis.33.

No. 60/854,540, filed on Oct. 26, 2006. the contents of which are hereby incorporated by reference in their entireties.Oxalic acid is a dicarboxylic acid of the formula HOC—COH. Oxalic acid exists primarily as oxalate in biological organisms, which is the salt form of oxalic acid. Oxalate is found in foods, such as, e.g., spinach, rhubarb, strawberries, cranberries, nuts, cocoa, chocolate, peanut butter, sorghum, and tea. Oxalate is also a metabolic end product in humans and other mammals. It is excreted by the kidneys into the urine. When combined with calcium, oxalic acid produces an insoluble product, calcium oxalate, which is the most prevalent chemical compound found in kidney stones. Because mammals do not synthesize enzymes that degrade oxalate, oxalate levels in an individual are normally held in check by excretion and low absorption of dietary oxalate. Elevated concentrations of oxalate are associated with a variety of pathologies, such as primary hyperoxaluria, enteric hyperoxaluria, and idiopathic hyperoxaluria. Leumann et al., 14:2556-2558 (1999) and Earnest, Adv. Internal Medicine 24:407-427 (1979). Increased oxalate can be caused by consuming too much oxalate from foods, by hyperabsorption of oxalate from the intestinal tract, and by abnormalities of oxalate production. Hyperabsorption of oxalate in the colon and small intestine can be associated with intestinal diseases, including hyperabsorption caused by diseases ...
