BACKGROUND Factors contributing to chronic inflammation appear to be associated with increased risk of ovarian cancer. The purpose of this study was to assess the association between circulating levels of inflammation mediators and subsequent risk of ovarian cancer. METHODS We conducted a case-control study of 230 cases and 432 individually matched controls nested within three prospective coh...
BACKGROUND AND PURPOSE We aim to investigate whether lower admission serum calcium levels are associated with hemorrhagic transformation (HT) after intravenous thrombolysis (IVT). METHODS A total of 362 patients treated with IVT was divided into 4 quartiles based on admission serum calcium levels (Q1[<2.16], Q2[2.16, 2.23], Q3[2.24, 2.31], and Q4[>2.31] mmol/L). HT was classified as hemorrhag...
Assume a database surrounded by a large variety of applications depending on it. For example, data entry or query forms are used by hundreds of users updating or querying information and complex workflows that operate in the enterprise frequently pose queries to the database. What happens if we delete a popular attribute from a relation in the database? Typically, all applications accessing thi...
OBJECTIVE Estimating the cost of chicken pox in a Colombian pediatric population. METHODOLOGY This was a retrospective case study which searched for all diagnosed chicken pox cases in the Napoleón Franco Pareja children's hospital (Cartagena, Colombia), during 2005-2008. The hospital's records/perspective was used. Cost related to health personnel, lab, diagnostic images and drugs were search...
A variational proof is provided of the existence and uniqueness of evolutions of regular Lagrangian systems. Introduction Let Q be a smooth, finite dimensional manifold and L : TQ → R be a smooth Lagrangian. Evolutions of the Lagrangian system defined by L are by definition the C curves q : [0, h] → R which are critical points of the action Sh = ∫ h 0 L ◦ q(t) dt, subject to the constraint that...
Davenport [2] used Kloosterman sum estimates to show that the above question is true for all ǫ > 1/3. Using Weil’s bound on Kloosterman sums (see equation (2)), Davenport’s argument implies the truth of Question 1 for all ǫ > 1/4. Recently in [11], Shparlinski got the same result with the further restriction that q1, q2 are relatively prime to one another. When q is a prime number, Garaev [6] o...
BACKGROUND AND PURPOSE The contribution of serum phosphate levels to stroke risk in dialysis patients remains unclear. The present study aimed to elucidate the respective association between serum phosphate levels and the risk of brain hemorrhage or infarction in patients undergoing hemodialysis. METHODS A total of 3437 patients undergoing hemodialysis were followed up for a median of 3.9 yea...
This study was conducted to investigate the relationship among the current status of calcium intake from milk and milk products, physical growth and bone mineral density in 664 male and female middle school and high school students aged 15-17 years. In the study, the current status of calcium intake from milk and milk products was analyzed, and the height, body composition, and bone mineral den...
