Serum carcinoembryonic antigen (s-CEA) is used to detect recurrence and predict prognosis in colorectal cancer. However, the cutoff values of s-CEA for prognosis have not been determined. We therefore tried to determine the preoperative s-CEA levels predictive of survivals in colorectal cancer patients. We retrospectively analyzed the medical records of 989 patients who underwent curative resec...

OBJECTIVES To determine the optimal cutoff value for neck circumference (NC) that define overweight/obesity and assess its predictive potential for cardiometabolic risks (CMR) among Saudi subjects.  Methods: A cross sectional study of 785 adults recruited from a public health awareness campaign in Medina, Saudi Arabia during June 2015. Waist circumference (WC), NC, body mass index (BMI), blood ...

OBJECTIVE To evaluate the diagnostic value of prostate-specific antigen density (PSAD) and the appropriate cutoff for the detection of prostate cancer. MATERIAL AND METHOD Between January 2008 and March 2011, 292 men with PSA levels between 4 and 10 ng/mL underwent transrectal ultrasonography (TRUS) with prostate biopsy. The diagnostic value of PSA levels and PSAD were compared using receiver...

I briefly review the source of the so-called intrinsic ambiguity and show how the combination of “golden” and “silver” channel at the Neutrino Factory can solve the problem, in the absence of other sources of degeneracies. I then relaxed the hypothesis θ23 = 45◦ and show how the different dependence of the two channels on θ23 can help in solving the intrinsic and θ23-octant ambiguity at the sam...

Background: Early detection of neonatal sepsis and categorization of patients based on clinical severity is not yet effectively achieved. Some hematological parameters are used to formulate a hematological scoring system (HSS) and a modified hematological scoring system (MHSS) to diagnose neonatal sepsis. A promising biomarker: Presepsin, or Soluble Cluster of Differentiation 14 SubType (sCD14-...

OBJECTIVE To determine the highest 50-g glucose challenge test (GCT) value that indicates no further diagnostic test is needed to confirm a diagnosis of gestational diabetes mellitus (GDM) under the criteria of National Diabetes Data Group (NDDG) or the Carpenter and Coustan (C&C) and fasting glucose thresholds from the International Association of Diabetes and Pregnancy Study Group (IADPSG). ...

identification of acid-fast bacilli (afb) in sputum or tissue samples is among definite diagnostic methods of tuberculosis. however, this method of diagnosis is restricted by certain limitations.   serologic diagnosis of tuberculosis (tb) has been used for a long time. the aim of this study was to determine the sensitivity and , specificity of antigen 60 (a60) igg, iga, igm test results in tb d...

CXCL13 in cerebrospinal fluid (CSF) could be an important component for diagnosing Lyme neuroborreliosis (LNB). Levels of intrathecal CXCL13 were determined for 58 LNB patients and 210 controls; sensitivity was 88% and specificity was 89% (cutoff, 250 pg of CXCL13/ml of CSF). Elevated levels of CXCL13 can aid in the diagnosis of LNB, but levels should be interpreted with care.
