BACKGROUND: Accurate reference intervals (RIs) based on a healthy pediatric population are essential for pediatric test result interpretation. The CALIPER project has recruited a large healthy cohort and completed a series of a priori studies to address gaps in pediatric RIs. As immunoassays from different manufacturers for endocrine and special chemistry markers are not standardized and show marked intermethod differences, direct RI studies are needed for each major analytical platform...

A mediator-free electrochemical immunosensor for quantitation of prostate specific antigen (PSA) based on dual signal amplification strategy was fabricated. In this work, PSA-antibody (anti-PSA) was immobilized onto a green and biocompatible nanocomposite containing poly L-cysteine (P-Cys) as conductive matrix and graphene quantum dots (GQDs)/gold nanoparticles (GNPs) as dual signal amplification elements. Therefore, a novel multilayer film based on P-Cys, GQDs, and GNPs was exploited to develop a highly sensitive amperometric immunosensor for detection of PSA...

BACKGROUND: Limited data are available for the use of agents in metastatic castration-resistant prostate cancer (mCRPC) beyond the third-line. We provide data during treatment with cabazitaxel (CAB), helping to improve the informed-consent process. PATIENTS AND METHODS: We retrospectively reviewed patients treated with fourth-line or beyond CAB for mCRPC after failure of previous therapies with docetaxel, abiraterone acetate, enzalutamide and/or radium-223. The progression-free survival (PFS) and the overall survival (OS) were estimated using the Kaplan-Meier method and compared to published data based on a structured literature review...

Prostate specific antigen (PSA) test is the most common, clinically validated test for the diagnosis of prostate cancer (PCa). While neoplastic lesions of the prostate may cause aberrant levels of PSA in the blood, the quantitation of free or complexed PSA poorly discriminates cancer patients from those developing benign lesions, often leading to invasive and unnecessary surgical procedures. Microenvironmental acidity increases exosome release by cancer cells. In this study we evaluated whether acidity, a critical phenotype of malignancy, could influence exosome release and increase the PSA expression in nanovesicles released by PCa cells...

Early cancer diagnosis remains the holy-grail in the battle against cancers progression. Tainted with debates and medical challenges, current therapeutic approaches for prostate cancer (PCa) lack early preventive measures, rapid diagnostic capabilities, risk factors identification, and portability, i.e. the inherent attributes offered by the label-free biosensing devices. Electronic assisted immunosensing systems inherit the high sensitivity and specificity properties due to the predilection of the antigen-antibody affinity...

OBJECTIVE Pan-brachial plexus injury (PBPI), involving C5-T1, disproportionately affects young males, causing lifelong disability and decreased quality of life. The restoration of elbow flexion remains a surgical priority for these patients. Within the first 6 months of injury, transfer of spinal accessory nerve (SAN) fascicles via a sural nerve graft or intercostal nerve (ICN) fascicles to the musculocutaneous nerve can restore elbow flexion. Beyond 1 year, free-functioning muscle transplantation (FFMT) of the gracilis muscle can be used to restore elbow flexion...
