Fundamental bounds on qubit reset
2020
Qubit reset is a basic prerequisite for operating quantum devices, requiring the export of entropy. The fastest and most accurate way to reset a qubit is obtained by coupling the qubit to an ancilla on demand. Here, we derive fundamental bounds on qubit reset in terms of maximum fidelity and minimum time, assuming control over the qubit and no control over the ancilla. Using the Cartan decomposition of the Lie algebra of qubit plus two-level ancilla, we identify the types of interaction and controls for which the qubit can be purified. For these configurations, we show that a time-optimal protocol consists of purity exchange between qubit and ancilla brought into resonance, where the maximu…
Eating disorders on the web: risks and resources.
2009
Our work is aimed at exploring the recent literature data on web sites, forums, and blogs, which promote eating disorders as normal life styles and their implication in the changes of the psychopatology of such disorders. We also want to understand whether new technologies have an impact in the course of the disorders or, on the other hand, whether they can also represent an instrument for searching help or information about them. The search strategy included a search of PsycINFO, Medline, and Ovid databases to identify research reports about pro-ana sites and their implication on the course of anorexia using the following key words: pro-ana, thinspiration, anorexia-web, online help eating …
Genioplasty with surgical guide using 3D-printing technology: A systematic review.
2019
The purpose of this systematic review is to evaluate the current state of the art of making genioplasties using 3D printing technology.
New diagnostic and imaging technologies in dermatology
2021
INTRODUCTION Diagnosis of dermatological disorders is primarily based on clinical examination in combination with histopathology. However, clinical findings alone may not be sufficient for accurate diagnosis and cutaneous biopsies are being associated with morbidity. OBJECTIVE The objective of this article is to review the newer technologies along with their applications, limitation and future prospectus. METHODOLOGY Comprehensive literature search was performed using electronic online databases "PubMed" and "Google Scholar". Articles published in English language were considered for the review. RESULTS In order to improve and/or widen the armamentarium in dermatologic disease diagnosis and…
Review of European and American guidelines for the diagnosis of Lyme borreliosis
2019
International audience; Lyme disease is a tick-borne bacterial disease with polymorphic clinical manifestations (cutaneous, rheumatological, and neurological). In recent years the issue of the diagnosis of this infection has been highly publicized on the Internet and other media in Europe and America. Some patients and physicians may share the perception that the diagnosis of the infection is not reliable in France. We reviewed current European and American guidelines on Lyme disease and performed a methodological evaluation of all guidelines. We retrieved 16 guidelines from seven countries. Our analysis revealed a global consensus regarding diagnosis at each stage of the infection. All gui…
Pathogen safety of long-term treatments for bleeding disorders: (un)predictable risks and evolving threats.
2013
Substantial improvements in the safety of blood and plasma products for the management of bleeding disorders have been achieved in recent decades. This has led some clinicians to believe that the infectious threat is over and that inhibitor formation is the foremost complication of hemophilia therapy. On the contrary, elimination of all microbes from blood is difficult, potentially impossible, and there are always threats from emerging pathogens. The risk of infection transmission is also increasing due to greater exposure to products, increasing prophylaxis and high-dose regimens for immune tolerance, and longevity of hemophilia patients. Current products can be considered "reasonably safe…
How to manage aspergillosis in non-neutropenic intensive care unit patients.
2014
Invasive aspergillosis has been mainly reported among immunocompromised patients during prolonged periods of neutropenia. Recently, however, non-neutropenic patients in the ICU population have shown an increasing risk profile for aspergillosis. Associations with chronic obstructive pulmonary disease and corticosteroid therapy have been frequently documented in this cohort. Difficulties in achieving a timely diagnosis of aspergillosis in non-neutropenic patients is related to the non-specificity of symptoms and to lower yields with microbiological tests compared to neutropenic patients. Since high mortality rates are typical of invasive aspergillosis in critically ill patients, a high level …
Disconnected Lives: Trends in Time Spent Alone in Finland
2020
AbstractDiscussions about social isolation have been extensive over the past few decades. A less sociable nature of social ties has been identified in Western societies. The phenomenon has been associated with demographic changes such as aging and living alone as well as changes in the use of new technologies. In this study we employ representative Finnish Time Use Surveys from three decades, 1987–1988 (n = 1887), 1999–2000 (n = 2673) and 2009–2010 (n = 1887) to examine the trends in social isolation, measured as time spent alone. Our results showed that between 1987 and 2010 the time spent alone increased by 124 min per day. The increase was linear and occurred in nearly all population gro…
Digital health interventions in children with asthma
2020
Abstract Although healthcare providers are actively involved in offering education, information and interventions for asthmatic patients, medication and therapeutic adherence remain low in the paediatric population, with estimates suggesting that adherence rates hover below 50%. A range of available digital health interventions has been explored in paediatric asthma with promising but variable results, limiting their widespread adoption in clinical practice. They include emerging technologies that yield the advantage of tracking asthma symptoms and medications, setting drug reminders, improving inhaler technique and delivering asthma education, such as serious games (video games designed fo…
The WFH Haemophilia Centre Twinning Programme: 10 years of growth, 1993-2003
2003
The World Federation of Haemophilia (WFH) Twinning Programme celebrates its tenth anniversary this year. Twinning is one of several international WFH programmes designed to improve haemophilia care at a global level. There are two types of twinning, and the haemophilia treatment centre twinning programme should be distinguished from the WFH haemophilia organization twinning involving national member organizations. The WFH Haemophilia Treatment Centre Twinning Programme helps emerging haemophilia treatment centres develop partnerships with well-established and experienced centres. Twinning can improve diagnosis and clinical care through coaching, training and transfer of expertise, ultimatel…
