An approach for a systematic description of the uncertainties and complexity of the standard animal testing and assessment approach for carcinogenicity is explored by using a draft OECD Guidance document that was originally developed for reporting defined in vitro approaches to testing and assessment (OECD, 2016). The format is suitable for this re-purposing and it appears that the potential multitude of approaches for integrating and interpreting data from standard animal testing may ultimately be conceptually similar to the challenge of integrating relevant in vitro and in silico data...

INTRODUCTION: Stump appendicitis is the remaining appendicular tissue inflammation after a variable length of time. It is a very infrequent pathology with a paucity in pediatric publications, and given the fact that a delay in its diagnosis could lead to an increased morbidity, this is the reason of its clinical relevance. CLINICAL CASE: A 10 years old girl who had laparoscopic excision of a flemonous-gangrenous appendicitis and who 45 days after surgery showed new clinical symptoms compatible with a diagnosis of acute appendicitis...

The relationship between patients and physicians has maintained its importance throughout human history because of special features of the medical profession. This relationship engendered true loyalty of patients to their physicians as well as serious legal conflicts. Medical malpractice has gained importance among physicians and ignited discussion because of new articles added to the Turkish Penal Code in 2005. In a very short time, the penalties mandated had a chilling, negative effect on doctors, resulting in loss of affection for the profession, hesitation to intervene, and burnout syndrome...

BACKGROUND: The etiology of HaNDL is not known. Recent neuroimaging studies have suggested that there may be altered cerebrovascular blood flow during acute episodes. However, what exactly these vascular changes represent and how they may relate to the overall pathogenesis of HaNDL is uncertain. CASE: A 42-year-old, right-handed male, presented with acute aphasia and right arm weakness. Urgent CT/CT-angiogram were normal except for an incidental hypoplastic right anterior cerebral artery (ACA) A1 segment...

INTRODUCTION:  Deep brain stimulator (DBS) infections are a persistent problem for patients undergoing this procedure. They may require further surgery, treatment with antibiotics, or even removal of the device. To date, no consensus exists on the best practices to avoid DBS infections or what factors predispose patients to an eventual infection. The goal of this study was to examine several patient factors for association with DBS infection. METHODS:  A single-center, single-surgeon quality improvement database was queried...

There are currently four known primate T-cell lymphotropic virus groups (PTLV1-4), each of which comprises closely related simian (STLV) and human (HTLV) viruses. For PTLV-1 and PTLV-3, simian and human viruses are interspersed, suggesting multiple cross-species transmission events; however, for PTLV-2 this is not so clear because HTLV-2 and STLV-2 strains from captive bonobos (Pan paniscus) form two distinct clades. To determine to what extent bonobos are naturally infected with STLV, we screened fecal samples (n = 633) from wild-living bonobos (n = 312) at six different sites in the Democratic Republic of Congo (DRC) for the presence of STLV nucleic acids...

Gaze-based interfaces and Brain-Computer Interfaces (BCIs) allow for hands-free human-computer interaction. In this paper, we investigate the combination of gaze and BCIs. We propose a novel selection technique for 2D target acquisition based on input fusion. This new approach combines the probabilistic models for each input, in order to better estimate the intent of the user. We evaluated its performance against the existing gaze and brain-computer interaction techniques. Twelve participants took part in our study, in which they had to search and select 2D targets with each of the evaluated techniques...

Currently drug eluting stents (DES) have reached a high degree of sophistication where there seems very little scope of improvement. Even so every year or so there is some advancement in technology and a new version is released, which is claimed to be a new generation (rather than pipeline innovation). It is really important to define what pipeline extension is and what is new innovation (generation)? This classification would not only be useful from regulatory perspective but also determining the true value of a product allowing for a correct pricing, which should ideally be able to mark-up for a real innovation...

In the 2014 WHO classification, squamous cell precursor lesions are classified as low-grade and high-grade intraepithelial lesions. LSIL corresponds to CIN1, HSIL includes CIN2 and CIN3. Only adenocarcinoma in situ (AIS) is accepted as precursor of adenocarcinoma and includes the stratified mucin-producing intraepithelial lesion (SMILE). Although relatively rare, adenocarcinoma and squamous cell carcinoma can be mixed with a poorly differentiated neuroendocrine carcinoma. Most cervical adenocarcinomas are low grade and of endocervical type...

In the 21st century, an array of microbiological and molecular allow antigens for new vaccines to be specifically identified, designed, produced and delivered with the aim of optimising the induction of a protective immune response against a well-defined immunogen. New knowledge about the functioning of the immune system and host pathogen interactions has stimulated the rational design of vaccines. The design toolbox includes vaccines made from whole pathogens, protein subunits, polysaccharides, pathogen-like particles, use of viral/bacterial vectors, plus adjuvants and conjugation technology to increase and broaden the immune response...

BACKGROUND: To reduce the burden of asthma, chronic disease management (CDM) programmes have been widely implemented and evaluated. Reviews including randomised controlled trials (RCTs) suggest that CDM programmes for asthma are effective. Other study designs are however often used for pragmatic reasons, but excluded from these reviews because of their design. We aimed to examine what complementary information could be retrieved from the addition of non-randomised studies to the studies included in a published Cochrane review on asthma CDM programmes, for healthcare stakeholders involved in the development, implementation, conduct or long-term sustainability of such programmes...

The position of Nurse Practitioner is a new role in Nordic countries. The transition from a registered nurse to the Nurse Practitioner role has been reported to be a personal challenge. This study, guided by the Nordic theoretical model for use in the education of advanced practice nurses, represents a unique opportunity to describe this transition for newly graduated Nurse Practitioners in an interprofessional surgical care team in Sweden. The aim was to explore how the first Nurse Practitioners in surgical care experienced the transition into a new role and what competences they used in the team...

Every day, in clinics and hospitals around the world, occupational therapists care for patients with serious problems requiring viable solutions. Each patient is unique, and his or her problem does not necessarily correspond to existing practice models. Practitioners must adapt standard approaches to provide effective outcomes, yet problems exist for which few or no beneficial approaches have been identified. Such clinical issues require solutions to be generated de novo from the practitioner's body of knowledge and past experience...

Learning to code the imagery, communication, and behavior associated with Rorschach responding is challenging. Although there is some survey research on graduate students' impressions of their Rorschach training, research has not identified which coding decisions students find to be the most problematic and time-consuming. We surveyed students to identify what they struggled with most when learning coding and to quantify how difficult it is to learn how to code. Participants (n = 191) from the United States, Brazil, Denmark, Israel, and Italy rated 57 aspects of coding using a 4-point scale that encompassed both the time required to code and the subjective difficulty of doing so...

The effective potentials are of great importance for the coarse-grained (CG) simulations, which can be obtained by the structure-based iterative Boltzmann inversion (IBI) method. However, the standard IBI method is incapable of keeping the mechanical and thermodynamic properties of the CG model in consistence with those of the all-atom model. Unlike the existed techniques, such as introducing the friction force as the dissipative force to drop the superatom motion while the conservative force arising from the CG potential was kept intact, we directly modified the standard IBI nonbonded potential by adding an empirical function...

It is well established that language production and comprehension are influenced by information status, for example, whether information is given, new, topical, or predictable, and many scholars suggest that an important component of information status is keeping track of what information is in common ground (i.e., what is shared), and what is not. Information status affects both speakers' choices (e.g., word order, pronoun use, prosodic prominence) and how listeners interpret the speaker's meaning (e.g., Chafe, 1994; Prince, 1981)...

OBJECTIVE: Innovative moments (IMs) are new and more adjusted ways of thinking, acting, feeling and relating that emerge during psychotherapy. Previous research on IMs has provided sustainable evidence that IMs differentiate recovered from unchanged psychotherapy cases. However, studies with cognitive behavioural therapy (CBT) are so far absent. The present study tests whether IMs can be reliably identified in CBT and examines if IMs and symptoms' improvement are associated. METHODS: The following variables were assessed in each session from a sample of six cases of CBT for depression (a total of 111 sessions): (a) symptomatology outcomes (Outcome Questionnaire-OQ-10) and (b) IMs...

We study the effect of film density on the uniaxial compression of thin elastic films at a liquid-fluid interface. Using a combination of experiments and theory, we show that dense films first wrinkle and then fold as the compression is increased, similarly to what has been reported when the film density is neglected. However, we highlight the changes in the shape of the fold induced by the film's own weight and extend the model of Diamant and Witten [Phys. Rev. Lett., 2011, 107, 164302] to understand these changes...

Clinical data management systems typically provide caregiver teams with useful information, derived from large, sometimes highly heterogeneous, data sources that are often changing dynamically. Over the last decade there has been a significant surge in interest in using these data sources, from simply re-using the standard clinical databases for event prediction or decision support, to including dynamic and patient-specific information into clinical monitoring and prediction problems. However, in most cases, commercial clinical databases have been designed to document clinical activity for reporting, liability and billing reasons, rather than for developing new algorithms...

BACKGROUND: Drinking of alcohol among university students is a global phenomenon; heavy episodic drinking is accepted despite several potential negative consequences. There is emerging evidence that short message service (SMS) text messaging interventions are effective to promote behavior change among students. However, it is still unclear how effectiveness can be optimized through intervention design or how user interest and adherence can be maximized. OBJECTIVE: The objective of this study was to develop an SMS text message-based intervention targeting alcohol drinking among university students using formative research...
