The Use of Biochip Cardiac Array Technology for Early Diagnosis of Acute Coronary SyndromesSerum troponin is the best biomarker for the diagnosis of acute coronary syndrome, but it takes considerable time before a definitive diagnosis is available. The purpose of this study was to evaluate whether a multimarker approach, using the biochip cardiac array, would facilitate the early diagnosis. Serum biomarkers were determined on admission (≤6 hrs) and after 6 hours in 42 patients suspected for ACS. Cardiac troponin I was measured by a sensitive assay (STATcTnI) and cardiac markers (H-FABP, myoglobin, cTnI, CK-MB mass, carbonic anhydrase III) were assayed with the use of Biochip Array Technology.STATcTnI concentrations, within the first 6 hours, were elevated >99thpercentile for the reference population in 83.3% of subjects, but none reached the cut-off for AMI. On admission H-FABP was the only marker with 90.5% sensitivity in all ACS cases and 100% sensitivity in STEMI/NSTEMI patients. The sensitivity of myoglobin at presentation was 71.4% in ACS, however, combined sensitivity of myoglobin and H-FABP reached 95.2%. Lowering the cut-off for cTnI allowed early diagnosis (≤6 hrs) in only 26.2% of ACS patients and 95.2% after the next 6 hours. In unstable angina the cardiac panel was not sufficiently accurate for early risk stratification. In conclusion, testing for both markers, H-FABP and sensitive cardiac troponin, available with the cardiac array may facilitate the early detection of myocardial injury in clinical practice.

Background: Hepatocellular carcinoma (HCC) is one of most common cancers with a high mortality rate. HBV/HCV infection is an important risk factor to trigger HCC. Therefore, developing serum biomarkers for early diagnosis is crucial to prolong survival in HCC patients. Methods: An antibody array technology was utilized to detect serum from 20 HBV-related HCC patients, 20 chronic hepatitis B patients and 20 normal population, whose results were further validated by ELISA. Results: Both antibody array and ELISA showed that ten growth factors (SCF R, GDF-15, HGF, FGF-4, IGFBP-1, PIGF, GH, GDNF, BDNF and IGF-1) were significantly differential in HCC patients when compared to the non-HCC population. Among these growth factors, the levels of SCF R, GDF-15, HGF, GH and IGF-1 showed significant correlation with hepatitis B and its severity, indicating that these growth factors may promote HCC progression by an HBV-specific mechanism. A therapy targeting these growth factors in hepatitis B patients may help to prevent the development of HCC. FGF4 and GH were found, for the first time, to be upregulated in HCC, suggesting that these two growth factors may serve as novel serum biomarkers for the early diagnosis of HCC. Conclusion: The combined detection of all the differential growth factors may improve the diagnostic accuracy of HCC.

To ensure optimal auditory development for the acquisition of spoken language, children with hearing loss require early diagnosis, effective ongoing audiological management, well fit and maintained hearing technology, and appropriate family-centered early intervention. When these elements are in place, children with hearing loss can achieve developmental and communicative outcomes that are comparable to their hearing peers. However, for these outcomes to occur, clinicians—early interventionists, speech-language pathologists, and pediatric audiologists—must participate in a dynamic process that requires careful monitoring of countless variables that could impact the child's skill acquisition. This paper addresses some of these variables or “red flags,” which often are indicators of both minor and major issues that clinicians may encounter when delivering services to young children with hearing loss and their families.

Objective:Cobalamin (B12) deficiency has been reported in infants born to mothers with low cobalamin intake. Early diagnosis of vitamin B12 deficiency in infants is critical for the prevention of neurobehavioral disorders. We investigated the relationship between serum vitamin B12 level in newborns and in their healthy mothers who consumed an omnivorous diet. Anthropometry was studied longitudinally to assess the growth velocity of the infants. Urinary methylmalonic acid (MMA) excretion of 6-month old infants was compared retrospectively as the biomarker correlated with the initial serum vitamin B12 concentrations. Methods: Serum cobalamin and blood hemoglobin were determined in 84 pairs of newborns and their mothers. Urinary MMA excretion was measured in the same subjects during the first 6 months of the post partum period. Results: At birth, median serum cobalamin levels were 152.0 pmol/L in the mothers and 296.6 pmol/L in the newborns. Maternal and neonatal serum cobalamin levels had no effect on growth velocity during the first six months of postnatal life. Serum maternal and neonatal cobalamin levels were inversely associated with urinary MMA excretion. Conclusion: Early diagnosis of vitamin B12 status in neonates and infants is crucial, particularly in nutritionally deprived areas. Biochemical measurement of plasma cobalamin or its metabolic marker MMA is highly recommended. Urinary MMA measurement in cobalamin diagnostics provides an advantage in that blood sampling is not required. A vitamin B12 taskforce should be created to alleviate vitamin deficiency and its negative consequences.
