Acute fibrinous and organizing pneumonia (AFOP) is a rare lung disease with distinct histological characteristics that include the diffuse presence of intra-alveolar fibrin, and the absence of eosinophils and hyaline membrane. In the present study, a case of AFOP that was diagnosed by lung biopsy is described. The patient presented with high fever and a cough with expectoration. Computed tomography of the lung showed the presence of bilateral patchy infiltrates, predominantly in the lower lobes. Histopathological examination of lung biopsy from the lower pulmonary lobe confirmed the pathological diagnosis...

BACKGROUND: Although mucosal thickening is the most common radiographic finding observed regarding sinus pathology, the knowledge regarding its clinical significance on the outcomes of dental implants and grafting in the maxillary sinuses is still limited. We hypothesized that mucosal thickening would not alter the predictability for sinus floor augmentation and dental implant placement. The purpose of this retrospective study was to evaluate the outcomes of dental implant placement in sinus-augmented areas with preexisting sinus mucosal thickening...

Identification of epitopes targeted by antibodies (B cell epitopes) is of critical importance for the development of many diagnostic and therapeutic tools. For clinical usage, such epitopes must be extensively characterized in order to validate specificity and to document potential cross-reactivity. B cell epitopes are typically classified as either linear epitopes, i.e. short consecutive segments from the protein sequence or conformational epitopes adapted through native protein folding. Recent advances in high-density peptide microarrays enable high-throughput, high-resolution identification and characterization of linear B cell epitopes...

BACKGROUND: Delirium is an acute confusional state, associated with morbidity and mortality in diverse medically ill populations. Delirium is preventable and treatable when diagnosed but the diagnosis is often missed. This important and difficult diagnosis is an attractive candidate for computer-aided decision support if it can be reliably identified at scale. OBJECTIVE: Here, using an electronic health record-based case definition of delirium, we characterize incidence of this highly morbid condition in 2 large academic medical centers...

Multiview learning has shown promising potential in many applications. However, most techniques are focused on either view consistency, or view diversity. In this paper, we introduce a novel multiview boosting algorithm, called Boost.SH, that computes weak classifiers independently of each view but uses a shared weight distribution to propagate information among the multiple views to ensure consistency. To encourage diversity, we introduce randomized Boost.SH and show its convergence to the greedy Boost.SH solution in the sense of minimizing regret using the framework of adversarial multiarmed bandits...

The computational reconstruction of ancestral proteins provides information on past biological events and has practical implications for biomedicine and biotechnology. Currently available tools for ancestral sequence reconstruction (ASR) are often based on empirical amino acid substitution models that assume that all sites evolve at the same rate and under the same process. However, this assumption is frequently violated because protein evolution is highly heterogeneous due to different selective constraints among sites...

A writer's biometric identity can be characterized through the distribution of physical feature measurements ("writer's profile"); a graph-based system that facilitates the quantification of these features is described. To accomplish this quantification, handwriting is segmented into basic graphical forms ("graphemes"), which are "skeletonized" to yield the graphical topology of the handwritten segment. The graph-based matching algorithm compares the graphemes first by their graphical topology and then by their geometric features...

Background Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) as respiratory and circulatory assist therapies are gaining in importance in the treatment of critically ill patients. Depending on the place of cannulation - veno-venous for ECMO and veno-arterial for ECLS - distinct changes in hemodynamics will occur. In this review we describe the different types of ECMO and ECLS systems, the typical cannula placement and frequent complications under therapy. The most suitable imaging modalities will be presented and typical hemodynamic pitfalls in contrast-enhanced computed tomography or angiography will be elucidated...

INTRODUCTION: School screening is warranted in developing countries that do not have newborn hearing screening as schools provide access to a large number of young children between 3 and 5 years of age. Due to scarcity of technical manpower and equipment, hearing screening programs are not often conducted in developing countries. In these circumstances, telehealth services appear to be a reasonable solution. Consequently, the purpose of this study was to assess the feasibility of school hearing screening using telehealth technology operated by a practitioner located 400 kms away at a distant hospital...

PURPOSE: Results of a study evaluating the predictive validity of a fall screening tool in hospitalized patients are reported. METHODS: Administrative claims data from two hospitals were analyzed to determine the discriminatory ability of the "medication fall risk score" (RxFS), a medication review fall-risk screening tool that is designed for use in conjunction with nurse-administered tools such as the Morse Fall Scale (MFS). Through analysis of data on administered medications and documented falls in a population of adults who underwent fall-risk screening at hospital admission over a 15-month period (n = 33,058), the predictive value of admission MFS scores, alone or in combination with retrospectively calculated RxFS-based risk scores, was assessed...
