OBJECTIVE: The etiology of necrotizing enterocolitis (NEC) remains elusive despite known associations with several factors, including intestinal ischemia related to the effects of umbilical arterial catheterization on the mesenteric circulation. However, the role of the mesenteric venous circulation has yet to be studied as a potential cause of NEC. We examined the association between umbilical venous catheter (UVC) position and the development of NEC in premature infants. DESIGN: A prospective cohort study was performed to examine the effect of UVC on portosystemic shunting via the ductus venosus (DV) and its potential role in NEC...

Most of the effort in image quality assessment (QA) has been so far dedicated to the degradation of the image. However, there are also many algorithms in the image processing chain that can enhance the quality of an input image. These include procedures for contrast enhancement, deblurring, sharpening, up-sampling, denoising, transfer function compensation, etc. In this work, possible strategies for the quality assessment of sharpened images are investigated. This task is not trivial because the sharpening techniques can increase the perceived quality, as well as introduce artifacts leading to the quality drop (over-sharpening)...

The current document was developed by the working group on the 'application of cardiac magnetic resonance' of the Italian Society of Cardiology to provide a perspective on the current state of technical advances and clinical cardiac magnetic resonance applications and to inform cardiologists how to implement their clinical and diagnostic pathway with the introduction of this technique in the clinical practice. Appropriateness criteria were defined using a score system: score 1-3 = inappropriate (test is not generally acceptable and is not a reasonable approach for the indication), score 4-6 = uncertain (test may be generally acceptable and may be a reasonable approach for the indication but more research and/or patient information is needed to classify the indication definitively) and score 7-9 = appropriate (test is generally acceptable and is a reasonable approach for the indication)...

BACKGROUND: Reports show that children with sickle-cell anemia (SCA) have a tendency for nocturnal enuresis when compared with their counterparts with normal hemoglobin. Although nocturnal enuresis in SCA has been attributed to several factors including tubular and even bladder dysfunction, its relationship with hyposthenuria has been questioned in some studies. AIM: The study aims to determine the relationship of hyposthenuria with nocturnal enuresis seen in school-aged children with SCA...

The laboratory, which utilizes some of the most sophisticated and rapidly changing technologies, plays a critical role in the diagnosis of tuberculosis. Some of these tools are being employed in resource-challenged countries for the rapid detection and characterization of Mycobacterium tuberculosis. Foremost, the laboratory defines appropriate specimen criteria for optimal test performance. The direct detection of mycobacteria in the clinical specimen, predominantly done by acid-fast staining, may eventually be replaced by rapid-cycle PCR...

INTRODUCTION: Obesity and overweight are an emerging problem in Africa. Obese children are at increased risk of developing hypertension, high cholesterol, orthopaedic problems and type 2 diabetes as well as increased risk of adult obesity. Prevention of childhood overweight and obesity therefore needs high priority. The review approach is particularly useful in establishing whether research findings are consistent and can be generalised across populations and settings. This systematic review aims to assess the magnitude and distribution of overweight and obesity among primary school learners within populations in Africa...

Human Herpesvirus-8(HHV-8)-negative, idiopathic multicentric Castleman disease (iMCD) is a rare and life-threatening disorder involving systemic inflammatory symptoms, polyclonal lymphoproliferation, cytopenias, and multiple organ system dysfunction due to a cytokine storm often including interleukin-6. iMCD accounts for one-third to one-half of all cases of MCD and can occur in individuals of any age. Accurate diagnosis is challenging, as no standard diagnostic criteria or diagnostic biomarkers currently exist, and there is significant overlap with malignant, autoimmune, and infectious disorders...

Identifying the number of classes in Bayesian finite mixture models is a challenging problem. Several criteria have been proposed, such as adaptations of the deviance information criterion, marginal likelihoods, Bayes factors, and reversible jump MCMC techniques. It was recently shown that in overfitted mixture models, the overfitted latent classes will asymptotically become empty under specific conditions for the prior of the class proportions. This result may be used to construct a criterion for finding the true number of latent classes, based on the removal of latent classes that have negligible proportions...

BACKGROUND: Cervical cancer can be prevented by effective screening using Papanicolaou tests, but the utilization rate is lower among ethnic minorities than in the general population. Understanding the factors influencing minorities' use of such screening can aid the design of an appropriate intervention to increase their uptake rate. OBJECTIVE: The aims of this study were to examine the factors that influence ethnic minority women in using cervical cancer screening and the similarities and differences in associated factors across different groups and to explore the interrelationships between the factors identified...

PURPOSE: Genomic sequencing (GS) for newborns may enable detection of conditions for which early knowledge can improve health outcomes. One of the major challenges hindering its broader application is the time it takes to assess the clinical relevance of detected variants and the genes they impact so that disease risk is reported appropriately. METHODS: To facilitate rapid interpretation of GS results in newborns, we curated a catalog of genes with putative pediatric relevance for their validity based on the ClinGen clinical validity classification framework criteria, age of onset, penetrance, and mode of inheritance through systematic evaluation of published evidence...

The identification/selection of appropriate patient subgroups with asymptomatic carotid artery stenosis and the performance of prophylactic carotid endarterectomy (CEA)/carotid artery stenting (CAS) exclusively on these asymptomatic patient subgroups is currently one of the "hottest" topics in vascular surgery. It is now clear that offering CEA/CAS to asymptomatic carotid patients based only on the degree of carotid stenosis is unjustified and scientifically flawed. On the other hand, offering only best medical therapy to every asymptomatic patient, irrespective of certain high-risk criteria (such as the detection of microemboli by transcranial Doppler, intraplaque hemorrhage, silent embolic infarcts on brain computed tomography/magnetic resonance imaging, elevated biomarkers, family history), is equally wrong...

BACKGROUND: Second-generation direct-acting antiviral agents are integral to treatment of hepatitis C (HCV) infection. Eight-week courses of ledipasvir/sofosbuvir (LDV/SOF) have been supported in some studies, but data are limited on efficacy in real-world use. Controversy exists regarding applicability of clinical trials to real-world effectiveness. We report virologic responses of patients with HCV genotype 1 infection receiving LDV/SOF for 8 or 12 weeks in a large integrated healthcare system...

BACKGROUND: Management of trauma patients with severe bleeding has led to criteria before considering use of recombinant activated factor VII (rFVIIa), including haemoglobin >8 g dl(-1), serum fibrinogen ≥1.0 g l(-1), platelets >50,000 x 10(9) l(-1), arterial pH ≥ 7.20, and body temperature ≥34 °C. We hypothesized that meeting these criteria is associated with improved outcomes. METHODS: In this prospective cohort study of 26 French trauma centres, subjects were included if they received rFVIIa for persistent massive bleeding despite appropriate care after severe blunt and/or penetrating trauma...
