INTRODUCTION: The BIFA concept (box isolation of fibrotic areas) supplementing pulmonary vein isolation (PVI) was implemented in atrial fibrillation (AF) patients with fibrotic atrial cardiomyopathy (FACM) to improve catheter ablation outcomes. METHODS AND RESULTS: 92 patients with FACM underwent PVI+BIFA. We investigated patient characteristics (58 persistent/34 paroxysmal,68±8y,LA 44±7mm,CHA2 DS2 -VASc 2.6±1.3,FACM I:15.2%,II:53.3%,III:26.1%,IV:5.4%), periprocedural data concerning fibrosis extent/distribution and their impact on outcome...

The ball and socket ankle joint is a morphologically abnormal joint characterized by rounding of the articular surface of the talus. Other than anecdotal observation, little evidence has been presented to describe the development of this deformity. The purpose of the present study was to review ankle and subtalar joint mechanics and to kinematically examine the functional combination of these joints as a mechanism of the ball and socket ankle deformity. We reviewed functional representations of the ankle joint, subtalar joint, and ball and socket ankle deformity...

Educators and commenters who evaluate big data-driven learning environments focus on specific questions: whether automated education platforms improve learning outcomes, invade student privacy, and promote equality. This article puts aside separate unresolved-and perhaps unresolvable-issues regarding the concrete effects of specific technologies. It instead examines how big data-driven tools alter the structure of schools' pedagogical decision-making, and, in doing so, change fundamental aspects of America's education enterprise...

Phenomenon: The integration of public health (PH) competency training into medical education, and further integration of PH and primary care, has been urged by the U.S. Institute of Medicine. However, PH competencies are numerous, and no consensus exists over which competencies are most important for adoption by current trainees. Our objective was to conduct a group concept mapping exercise with stakeholders identifying the most important and feasible PH skills to incorporate in medical and residency curricula...

Phenomenon: Despite the promotion of medical student health and wellness through recent program and curricular changes, research continues to show that medical education is associated with decreased well-being in medical students. Although many institutions have sought to more effectively assess and improve self-care in medical students, no self-care initiatives have been designed using the explicit perspectives of students themselves. APPROACH: Using concept mapping methodology, the research team created a student-generated taxonomy of self-care behaviors taken from a national sample of medical students in response to a brainstorming prompt...

CONTEXT: Concept maps (CMs) were tested for their effectiveness in teaching pathology in a conceptual manner. AIMS: To correlate the quality of CMs drawn by students with their performance on tests involving clinical problem-solving. SUBJECTS AND METHODS: Students were taught "how, why, and so what" about CMs at the start of the course. Each student drew one CM every week and a minimum of ten throughout the course and submitted them for evaluation and corrections...

Mapping individual patterns of decline in older adults may aid coordinating long term aged care. This study developed a new scale (Transition Maps) to summarise the overall care pathway for long term aged care residents, in a simplified manner incorporating mapping concepts. Transition Maps were developed using mixed methods in two phases, and based on expert opinion, literature review, and input from aged care health professionals. Four professions (primary physician, nurse, allied health, lifestyle services) generated 147 Transition Maps for 38 residents living in a long term care...

BACKGROUND: Recently, the metabolite-likeness of the drug space has emerged and has opened a new possibility for exploring human metabolite-like candidates in drug discovery. However, the applicability of metabolite-likeness in drug discovery has been largely unexplored. Moreover, there are no reports on its applications for the repositioning of drugs to possible enzyme modulators, although enzyme-drug relations could be directly inferred from the similarity relationships between enzyme's metabolites and drugs...

REVIEW
Shinichi Kinami, Takeo Kosaka
Currently, the most accurate method for identifying lymph node metastasis is intraoperative diagnosis by sentinel node (SN) biopsy. Based on the SNNS study-a recent large-scale, nationwide, multicenter prospective study-the SN concept seems to be scientifically valid in patients with early gastric cancer. SN biopsy is a multistep technique consisted of six essential elements: indication, the selection of a tracer, a proper tracer injection method, the objective detection of SNs, a reliable biopsy technique, and the precise detection of nodal metastasis...

BACKGROUND: Parents are widely recognized as playing a central role in the development of child behaviors such as physical activity. As there is little agreement as to the dimensions of physical activity-related parenting practices that should be measured or how they should be operationalized, this study engaged experts to develop an integrated conceptual framework for assessing parenting practices that influence multiple aspects of 5 to 12 year old children's participation in physical activity...

This paper discusses part of the results obtained from a study carried out in two cities of the so-called ABCD Paulista Region in the period 2010-2012, in an attempt to spot the existence of non-state regulatory rationale towards access and consumption of health care services. The first stage includes interviews carried out with strategic stakeholders (managers and politicians) and key workers players. The second stage collected the stories of 18 very frequent users of health care services. This study revealed the leading role played by users to produce "health care maps", with emphasis on the frequent use of public and private resources in their itineraries, circumventing or merging with government regulation to obtain the care they need...

The subgenus Niphetoscapha Heller 1914 of Gymnopholus Heller 1901 is revised. It is characterized by the morphology of the elytral apex and the asymmetrical tip of the penis. Vestigial wings and a fused elytral suture indicate flightlessness. Gymnopholus (Niphetoscapha) inexspectatus sp. n. is described as new, exhibiting a distinct epizoic symbiosis with algae otherwise known from the subgenus Symbiopholus Gressitt 1966. The four species of Niphetoscapha inhabit the central mountain range of West New Guinea: Gymnopholus audax Gressitt 1966, G...

Diffuse low-grade glioma (DLGG) is a chronic tumoral disease that ineluctably grows, migrates along white matter pathways, and progresses to a higher grade of malignancy. Areas covered: To determine the best individualized treatment attitude for each DLGG patient, and to redefine it over the years, i.e. to optimize the "onco-functional balance" of serial and multimodal therapies, the understanding of the natural history of this chronic disease is crucial but not sufficient. A paradigmatic shift is to tailor the individual management according to the dynamic relationships between DLGG course and neural remodeling...

The purpose of this concept study was to investigate the possibility of automatic mean arterial pressure (MAP) regulation in a porcine heart-beating brain death (BD) model. Hemodynamic stability of BD donors is necessary for maintaining acceptable quality of donated organs for transplantation. Manual stabilization is challenging, due to the lack of vasomotor function in BD donors. Closed-loop stabilization therefore has the potential of increasing availability of acceptable donor organs, and serves to indicate feasibility within less demanding patient groups...

BACKGROUND: Takotsubo syndrome is an increasingly recognized cause of chest pain and occasionally of cardiogenic shock. Despite rapid improvement of the left ventricular (LV) ejection fraction, recent registry data raise concerns about long-term prognosis. The aim of this study was to test the hypothesis that restoration of normal ejection fraction after acute takotsubo syndrome is not equivalent to full functional recovery. METHODS: Fifty-two patients with takotsubo syndrome (according to the Mayo Clinic criteria plus cardiac magnetic resonance imaging to exclude myocardial infarction) and 44 healthy control subjects of the same age, gender, and cardiovascular comorbidity distribution were prospectively recruited...

OBJECTIVES: Magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) is a method to heat lesions noninvasively to a stable, elevated temperature and a well-suited method to induce local hyperthermia (41°C-43°C) in deep-seated tissues. Magnetic Resonance (MR) imaging provides therapy planning on anatomical images and offers temperature feedback based on near-real-time MR thermometry. Although constant acquisition of MR thermometry data is crucial to ensure prolonged hyperthermia, it limits the freedom to perform measurements of other MR parameters, which are of interest during hyperthermia treatments...

BACKGROUND: Shared mental models are crucial for constructing mutual understanding of the patient's condition during a clinical handover. Yet, scant research, if any, has empirically explored mental models of the parties involved in a clinical handover. OBJECTIVES: This study aimed to examine the similarities among mental models of incoming and outgoing nurses, and to test their accuracy by comparing them with mental models of expert nurses. DESIGN: A cross-sectional study, exploring nurses' mental models via the concept mapping technique...

The normal mapping technique is widely used in computer graphics to visualize three-dimensional (3D) objects displayed on a flat screen. Taking advantage of optical properties of metasurfaces, which provide a highly efficient approach for manipulation of incident light wavefront, we have designed a metasurface to implement diffuse reflection and used the concept of normal mapping to control its scattering properties. As a proof of principle, we have fabricated and characterized a flat diffuse metasurface imitating lighting and shading effects of a 3D cube...
