BACKGROUND: Increased serum levels of procalcitonin (ProCT) and its component peptides have been reported in humans with sepsis. Using a hamster model of bacterial peritonitis, we investigated whether serum ProCT levels are elevated and correlate with mortality and hypocalcemia. RESULTS: Incremental increases in doses of bacteria resulted in proportional increases in 72h mortality rates (0, 20,...

Healthy term babies undergo a physiological nadir in serum calcium levels by 24-48 hours of age. The nadir may be related to the delayed response of parathyroid and calcitonin hormones in a newborn. This nadir may drop to hypocalcemic levels in high-risk neonates including infants of diabetic mothers, preterm infants and infants with perinatal asphyxia. The early onset hypocalcemia which presen...

CONTEXT Adequate vitamin D status for optimum bone health has received increased recognition in recent years; however, the ideal intake is not known. Serum 25-hydroxyvitamin D is the generally accepted indicator of vitamin D status, but no universal reference level has been reached. OBJECTIVE To investigate the relative importance of high calcium intake and serum 25-hydroxyvitamin D for calci...

Introduction. Patients with rheumatoid arthritis (RA) are twice as likely to have osteoporosis (OP) compared the general population. The strength of bones depends on mineral substances, mainly represented by calcium phosphate microcrystals. chief role in regulation calcium-phosphorus metabolism is played vitamin D and parathormone (PTH). aim study. To investigate markers patients accompanied bo...

common carp, cyprinus carpio (l.) were blood-sampled after 0, 2, 6, 12, 24, 48 and 72 h fasting to find serum baseline levels. there was a significant difference in serum glucose, lactate, triglyceride and total protein but not cholesterol, albumin and calcium levels among the treatments. glucose levels increased with fasting tine and reached to a peak after 6 h. then, the glucose level decreas...

The main objective of this study was to identify the incidence of post-thyroidectomy hypocalcemia in patients underwent lobectomy, subtotal thyroidectomy or total thyroidectomy. This randomized trial study was performed from May 2010 to July 2011 among 108 consecutive patients undergoing thyroidectomy. Patients were allocated into 3 groups based on the 3 common type of thyroidectomy. Pre and po...

OBJECTIVES To evaluate total serum calcium (TC) and albumin-corrected calcium (ACC) as prognostic severity factors in acute pancreatitis (AP). METHODS Ninety-six patients were included in the study. They were diagnosed with AP and admitted to the Hospital Regional de Veracruz within the time frame of January 2010 to December 2012. AP severity was determined through the updated Atlanta Classif...

CONTEXT The effect of calcium carbonate on the absorption of levothyroxine has not been studied systematically. Such a potential drug interaction merits investigation because concurrent treatment with both drugs is common, particularly in postmenopausal women. OBJECTIVE To investigate the potential interference of calcium carbonate in the absorption of levothyroxine. DESIGN Prospective coho...
