Thyroid papillary carcinoma is the most common endocrine neoplasm and generally carries a favorable prognosis. However, a small subset of papillary carcinomas transforms into anaplastic carcinoma, an undifferentiated cancer with a dismal prognosis. Recent studies using next-generation sequencing revealed the genomic landscape of papillary carcinoma and anaplastic carcinoma. However, risk factors for anaplastic transformation in papillary carcinoma remain obscure. In the present study, we investigated molecular alterations of papillary carcinoma and anaplastic carcinoma components in 27 tumors in which anaplastic carcinoma coexisted with antecedent papillary carcinoma...

Low grade follicular lymphoma (FL1/2) has an annual risk of transformation of approximately 3% which is associated with aberrations in CDKN2A/B, TP53 and MYC. Like in DLBCL high MYC expression in transformed FL (tFL) might predict a MYC breakpoint. We quantified MYC expression by immunohistochemistry and digital analysis in 41 paired biopsies from 20 patients with FL1/2 with subsequent transformation and in 4 isolated biopsies of tFL. As controls 28 biopsies of FL1/2 without transformation (median follow up 105 months) and 9 FL3A/B were analyzed...

Firearm homicide is the leading cause of violence-related youth mortality. To inform prevention efforts, we analyzed event-level data to identify unique precursors to firearm conflicts. Youth (ages:14-24) seeking Emergency Department (ED) treatment for assault or for other reasons and reporting past 6-month drug use were enrolled in a 2-year longitudinal study. Time-line follow-back substance use/aggression modules were administered at baseline and each 6-month follow-up. Violent non-partner conflicts were combined across time-points...

Teams are the building blocks of the healthcare system, with growing evidence linking the quality of health care to team effectiveness, and team effectiveness to team training. Simulation has been identified as an effective modality for team training and assessment. Despite this, there are gaps in methodology, measurement, and implementation that prevent maximizing the impact of simulation modalities on team performance. As part of the 2017 Academic Emergency Medicine Consensus Conference "Catalyzing System Change through Health Care Simulation: Systems, Competency, and Outcomes," we explored the impact of simulation on various aspects of team effectiveness...

Objective Premature birth is associated with numerous complex abnormalities of white and grey matter and a high incidence of long-term neurocognitive impairment. An integrated understanding of these abnormalities and their association with clinical events is lacking. The aim of this study was to identify specific patterns of abnormal cerebral development and their antenatal and postnatal antecedents. Methods In a prospective cohort of 449 infants (226 male), we performed a multi-variate and data-driven analysis combining multiple imaging modalities...

BACKGROUND: The last few decades saw an intense development in information technology (IT) and it has affected the ways organisations achieve their goals. Training, in every organisation is an ongoing process that aims to update employees' knowledge and skills towards goals attainment. Through adequate deployment of IT, organisations can effectively meet their training needs. However, for successful IT integration in training, the employees who will use the system should be positively disposed towards it...

In order to reduce road accidents rates, studies around the globe have attempted to shed light on the antecedents for unsafe road behaviors. The aim of the current research is to contribute to this literature by offering a new organizational antecedent of driver's unsafe behavior: The driver's relationships with his or her peers, as reflected in three types of social networks: negative relationships network, friendship networks and advice networks (safety consulting). We hypothesized that a driver's position in negative relationship networks, friendship networks, and advice networks will predict unsafe driving...

Guillain-Barre Syndrome (GBS) is a life-threatening condition in which patients may present to the Emergency Department in respiratory distress leading to death. The early identification and treatment of such a condition is paramount in preventing mortality. While there are many infections associated with GBS, the association with Lyme disease is uncommon. Through our case we aim to highlight Borrelia burgdorferi as an important antecedent infection associated with the development of GBS. In this case we report a 31-year-old male who was diagnosed with Lyme disease and GBS with relevant clinical presentation including progressive numbness and weakness in bilateral hands and feet for the past 1week along with areflexia...

Mid-trimester preterm premature rupture of membranes (PPROM), defined as rupture of fetal membranes prior to 28 weeks of gestation, complicates approximately 0.4%-0.7% of all pregnancies. This condition is associated with a very high neonatal mortality rate as well as an increased risk of long- and short-term severe neonatal morbidity. The causes of the mid-trimester PPROM are multifactorial. Altered membrane morphology including marked swelling and disruption of the collagen network which is seen with PPROM can be triggered by bacterial products or/and pro-inflammatory cytokines...

BACKGROUND: De-escalation is the recommended first-line response to potential violence and aggression in healthcare settings. Related scholarly activity has increased exponentially since the 1980s, but there is scant research about its efficacy and no guidance on what constitutes the gold standard for practice. OBJECTIVES: To clarify the concept of de-escalation of violence and aggression as described within the healthcare literature. DESIGN: Concept analysis guided by Rodgers' evolutionary approach...

Goal-directed actions are controlled by the value of the consequences they produce and so increase when what they produce is valuable and decrease when it is not. With continued invariant practice, however, goal-directed actions can become habits, controlled not by their consequences but by antecedent, reward-related states and stimuli. Here, we show that pre-exposure to methamphetamine (METH) caused abnormally rapid development of habitual control. Furthermore, these drug-induced habits differed strikingly from conventional habits; we found that they were insensitive both to changes in reward value and to the effects of negative feedback...

This study examined (a) transition patterns from adolescent-specific depressive symptom trajectory classes to young adult-specific trajectory classes (N = 537; 15-26 years) and (b) identified risk factors associated with these transition patterns. The latent classes and transition analyses identified three transitional patterns of depressive symptom trajectories, including a deteriorating pattern (8.2%), a recovering pattern (22.5%), and a consistently low pattern (69.3%). Additionally, the results showed that contextual risk factors (i...

INTRODUCTION: Workplace violence is one of the most significant and hazardous issues faced by nurses globally. It is a potentially life-threatening and life-affecting workplace hazard often downplayed as just "part of the job" for nurses. METHODS: A cross-sectional design was used and data were collected using a purpose developed survey tool. Surveys were distributed to all members of the College of Emergency Nurses' Australasia (CENA) in 2010 and 537 eligible responses were received (RR=51%)...

INTRODUCTION: Prior studies have shown an association between the onset of hepatonephritis and the use of arteminisin-based combination therapy (ACT) during the treatment of uncomplicated malaria. The objective of this study was to identify the risk factors of hepatonephritis occurrence because of the uncertainty regarding the appearance and the aggravation of this syndrome. METHODS: A case-non case study was carried out on 428 notifications of pharmacovigilance extracted from the database of the clinical pharmacology department of the teaching hospital of Cocody from 2008 to 2012...

Previous research has suggested that adolescent peers influence behavior and provide social support during a critical developmental period, but few studies have addressed the antecedents of adolescent social networks. Research on the collateral consequences of incarceration has explored the implications of parental incarceration for children's behavioral problems, academic achievement, health, and housing stability, but not their social networks. Using network data from the National Longitudinal Study of Adolescent Health, I find that adolescents with recently incarcerated fathers are in socially marginal positions in their schools and befriend more-marginal peers than other adolescents: their friends are less advantaged, less academically successful, and more delinquent than other adolescents' friends...

HIV and childhood sexual abuse (CSA) are intersecting public health problems for women. We pilot tested an integrated sexual risk reduction intervention for women with a history of CSA that addressed both the consequences of CSA [based on the Traumagenic Dynamics (TD) framework] and the antecedents of sexual risk behavior (based on the Information-Motivation-Behavioral Skills [IMB] model). Women with a history of CSA who were attending a public STI clinic (n = 84) were randomly assigned to a five-session integrated TD/IMB (experimental) group intervention or to a time-matched IMB-guided sexual risk reduction (control) group intervention...

BACKGROUND: Ecological models emphasise multilevel influences on health behaviours. While studies show that exposure to price promotions is associated with smoking behaviour and its antecedents, less is known about whether these associations differ by macro-level factors such as national price promotion policies. METHODS: Current and former smokers (N=4698) from the International Tobacco Control Policy Evaluation Project four-country cohort were included in weighted multivariate logistic regression models to examine individual-level associations between exposure to price promotions at waves 7 and 8 (conducted in 2008-2009 and 2010-2011) and beliefs (social and injunctive norms, functional value of smoking, misconceptions around smoking and beliefs of tobacco industry and its regulations) and behaviour at wave 8, stratified by whether countries allow (Australia and USA) or ban (Canada and UK) price promotions...
