OBJECTIVES: To investigate the impact of the body composition such as skeletal muscle, visceral fat and body mass index (BMI) on patients with resected pancreatic ductal adenocarcinoma (PDAC). METHODS: A total of 265 patients who underwent curative surgery for PDAC were examined in this study. The total skeletal muscle and fat tissue areas were evaluated in a single image obtained at the third lumber vertebra during a preoperative computed tomography (CT) scan. The patients were assigned to either the sarcopenia or non-sarcopenia group based on their skeletal muscle index (SMI) and classified into high visceral fat area (H-VFA) or low VFA (L-VFA) groups...

PURPOSE: Routine screening for disordered eating or body image concerns is recommended by the American Academy of Pediatrics. We evaluated the ability of two educational interventions to increase screening for eating disorders in pediatric primary care practice, predicting that the "active-learning" group would have an increase in documented screening after intervention. METHODS: We studied 303 practitioners in a large independent practice association located in the northeastern United States...

The skin and brain have a close bi-directional anatomical and functional connection. Historically, the skin-brain axis and the brain-skin axis have been well described. However, brain function in this context has only recently been demystified with the introduction of functional neuroimaging in dermatology. Functional neuroimaging, especially functional magnetic resonance imaging (fMRI), allows indirect visualisation of brain function. This review looks back to the beginnings of functional neuroimaging in dermatology, summarises the currently available dermatology-related fMRI-studies and discusses the potential future role of fMRI as a stratifying tool in clinical dermatology and in the development of novel therapies...

Fungi are noted producers of a diverse array of secondary metabolites, many of which are of pharmacological importance. However, the biological roles of the vast majority of these molecules during the fungal life cycle in nature remain elusive. Solanapyrones are polyketide-derived secondary metabolites produced by diverse fungal species including the plant pathogen Ascochyta rabiei. This molecule was originally thought to function as a phytotoxin facilitating pathogenesis of A. rabiei. Chemical profiling and gene expression studies showed that solanapyrone A was specifically produced during saprobic, but not parasitic growth of A...

Only few electron microscopic studies exist on the structure of the main eyes (anterior median eyes, AME) of web spiders. The present paper provides details on the anatomy of the AME in the funnel-web spider Agelena labyrinthica. The retina consists of two separate regions with differently arranged photoreceptor cells. Its central part has sensory cells with rhabdomeres on 2, 3, or 4 sides, whereas those of the ventral retina have only two rhabdomeres on opposite sides. In addition, the rhabdomeres of the ventral retina are arranged in a specific way: Whereas in the most ventral part they form long tangential rows, those towards the center are detached and are arranged radially...

This study tested the hypothesis that latent class analysis (LCA) would successfully classify eating disorder (ED) symptoms in children into categories that mapped onto DSM-5 diagnoses and that these categories would be consistent across countries. Childhood onset ED cases were ascertained through prospective active surveillance by the Australian Paediatric Surveillance Unit, the Canadian Paediatric Surveillance Program, and the British Paediatric Surveillance Unit for 36, 24, and 14 months, respectively. Pediatricians and child psychiatrists reported symptoms of any child aged ≤ 12 years with a newly diagnosed restrictive ED...

The research on hand gestures has attracted many image processing-related studies, as it intuitively conveys the intention of a human as it pertains to motional meaning. Various sensors have been used to exploit the advantages of different modalities for the extraction of important information conveyed by the hand gesture of a user. Although many works have focused on learning the benefits of thermal information from thermal cameras, most have focused on face recognition or human body detection, rather than hand gesture recognition...

Perceptual illusions across multiple modalities, such as the rubber-hand illusion, show how dynamic the brain is at adapting its body image and at determining what is part of it (the self) and what is not (others). Several research studies showed that redundancy and contingency among sensory signals are essential for perception of the illusion and that a lag of 200-300 ms is the critical limit of the brain to represent one's own body. In an experimental setup with an artificial skin, we replicate the visuo-tactile illusion within artificial neural networks...

PURPOSE: Accurate reconstruction of the dose delivered by (90) Y microspheres using a postembolization PET scan would permit the establishment of more accurate dose-response relationships for treatment of hepatocellular carcinoma with (90) Y. However, the quality of the PET data obtained is compromised by several factors, including poor count statistics and a very high random fraction. This work uses Monte Carlo simulations to investigate what impact factors other than low count statistics have on the quantification of(90) Y PET...

PURPOSE: Young adult (YA) cancer survivors report substantial distress, social isolation, and body image concerns that can impede successful reintegration into life years after treatment completion. Mindful Self-Compassion (MSC) interventions focus on developing mindfulness and self-compassion for managing distress, hardships, and perceived personal inadequacies. An MSC intervention would be beneficial in supporting YA survivors' management of psychosocial challenges that arise in survivorship; however, a telehealth intervention modality is essential for reaching this geographically dispersed population...

BACKGROUND: Restricted diffusion within the splenium of the corpus callosum has been described by other authors in various conditions, however, restricted diffusion in the entire corpus callosum or isolated involvement of the splenium, genu, or body has been infrequently reported on magnetic resonance imaging (MRI) in neonatal hypoxic-ischemic encephalopathy. We report a series of cases showing different patterns of involvement. METHODS AND MATERIALS: Perinatal imaging with MRI including diffusion-weighted imaging was performed in 40 neonates with hypoxic-ischemic encephalopathy, including 11 premature neonates...

Lymphatic malformations are congenital vascular malformations with lymphatic differentiation. Although the most common locations for lymphatic malformation are the neck and axilla, they can occur at several locations in the body including the abdomen. The abdominal location is rather rare and accounts for approximately 5% of all lymphatic malformation. Abdominal lymphatic malformation can arise from mesentery, omentum, gastrointestinal tract, and retroperitoneum. Clinical presentation includes an abdominal lump, vague abdominal discomfort, and secondary complications including intestinal obstruction, volvulus, ischemia, and bleeding...

OBJECTIVES: Overexpression of human epidermal growth factor receptor 2 (HER2) plays important roles in tumorigenesis and tumor progression in breast cancer. Nuclear imaging of HER2 expression in tumors might detect all HER2-positive tumors throughout the body and guide HER2-targeted therapies for patients. We therefore aimed to develop a HER2-targeted peptide probe for breast cancer imaging. A novel single-photon emission computed tomography (SPECT) imaging probe, (99m)Tc-HYNIC-H6F, was prepared and then evaluated in breast cancer animal models...

Brown adipose tissue (BAT) provides a means of non-shivering thermogenesis. In humans, active BAT can be visualized by (18)F-fluoro-desoxyglucose (FDG) uptake as detected by positron emission tomography (PET) combined with computer tomography (CT). The retrospective analysis of clinical scans is a valuable source to identify anthropometric parameters that influence BAT mass and activity and thus the potential efficacy of envisioned drugs targeting this tissue to treat metabolic disease. We analyzed 2854 FDG-PET/CT scans from 1644 patients and identified 98 scans from 81 patients with active BAT...

BACKGROUND: Endocardial mapping tools use variable inter-electrode resolution whilst body surface mapping tools use narrow band pass filtering (BPF) to map fibrillatory mechanisms established by high resolution optical imaging. OBJECTIVES: To study the effect of resolution and BPF on the underlying mechanism being mapped. METHODS: Hearts from 14 healthy New Zealand white rabbits were Langendorff perfused. We studied the effect of spatial resolution and BPF on the location and characterization of rotors, by comparing phase singularities (PS) detected by high resolution un-filtered optical maps (OM), of fibrillating myocardium with decimated and filtered maps with simulated electrode spacing of 2, 5 and 8mm...

BACKGROUND: The objective assessment of global and regional cardiac function in children has shown to be clinically relevant but is challenging to conduct. Cardiovascular magnetic resonance (CMR) has emerged as a valuable diagnostic modality especially in patients with cardiomyopathy or congenital heart disease. However, data on the normal cardiac deformation in children assessed by CMR is lacking at present. Thus, the aim of this study was to provide reference values for cardiac strain and strain rate in children and adolescents derived from CMR feature tracking (FT) measurements...

The British Association for Psychopharmacology coordinated a meeting of experts to review and revise its previous 2011 guidelines for clinical practice with anti-dementia drugs. As before, levels of evidence were rated using accepted standards which were then translated into grades of recommendation A-D, with A having the strongest evidence base (from randomised controlled trials) and D the weakest (case studies or expert opinion). Current clinical diagnostic criteria for dementia have sufficient accuracy to be applied in clinical practice (B) and both structural (computed tomography and magnetic resonance imaging) and functional (positron emission tomography and single photon emission computerised tomography) brain imaging can improve diagnostic accuracy in particular situations (B)...
