background: peripherally inserted central catheter (picc) is commonly used in nursing for patients with leukemia. the purpose of this study was to investigate the risk factors of catheter-related infection (cri) in patients with leukemia and to provide some nursing strategies based on the results. methods: clinical data from 140 patients with leukemia between may 2014 and july 2016 in haiyang p...

BACKGROUND Meta-analyses were performed to examine the utility of ultrasonography, computed tomography (CT), positron emission tomography (PET), and a combination of both (PET-CT) for the staging and surveillance of melanoma patients. METHOD Patient-level data from 74 studies containing 10,528 patients (between January 1, 1990, and June, 30, 2009) were used to derive characteristics of the di...

BACKGROUND UK estimates of age related macular degeneration (AMD) occurrence vary. AIMS To estimate prevalence, number and incidence of AMD by type in the UK population aged ≥50 years. METHODS Age-specific prevalence rates of AMD obtained from a Bayesian meta-analysis of AMD prevalence were applied to UK 2007-2009 population data. Incidence was estimated from modelled age-specific prevalenc...

Compensatory reserve was measured in baboons (n = 13) during hemorrhage (Hem) and lower-body negative pressure (LBNP) using a machine-learning algorithm developed to estimate compensatory reserve by detecting reductions in central blood volume during LBNP. The algorithm calculates compensatory reserve index (CRI) from normovolemia (CRI = 1) to cardiovascular decompensation (CRI = 0). The hypoth...

Evaluation of tests for the diagnosis of childhood pulmonary tuberculosis (CPTB) is complicated by the absence of an accurate reference test. We present a Bayesian latent class analysis in which we evaluated the accuracy of 5 diagnostic tests for CPTB. We used data from a study of 749 hospitalized South African children suspected to have CPTB from 2009 to 2014. The following tests were used: my...
