BACKGROUND: Implementation of point-of-care ultrasonography (POCUS) of the heart and lungs requires image acquisition skills among providers. We aimed to determine the effect of POCUS implementation using a systematic education program on image acquisition skills and subsequent use and barriers in a department of anesthesiology. METHODS: Twenty-five anesthesiologists underwent a systematic education program in POCUS during the fall of 2012. A POCUS expert evaluated images from baseline and evaluation examinations performed on two healthy individuals as useful or not useful for clinical interpretation...

BACKGROUND: The multicenter, single-blind, randomized EU-PACT trial compared safety and efficacy of genotype-guided and non-genetic dosing algorithms for acenocoumarol and phenprocoumon in patients with atrial fibrillation or deep venous thrombosis. The trial showed no differences in the primary outcome between the two dosing strategies. OBJECTIVES: To explore possible reasons for the lack of differences between trial arms this secondary analysis of EU-PACT data evaluated the performance of both dosing algorithms across VKORC1-CYP2C9 genetic sub-groups...

Zika virus infection is an emerging mosquito-borne disease, first identified in Uganda in 1947. It is caused by the Zika arbovirus, and transmitted by the bites of infected mosquitoes of the genus Aedes. For almost half a century, the Zika virus was reported as the causative agent of sporadic human infections. In 2007, the Zika virus emerged outside Asia and Africa causing an epidemic on the Island of Yap in Micronesia. The manifestation of the newly acquired human infection varies from asymptomatic to self-limiting acute febrile illness with symptoms and clinical features similar to those caused by the Dengue virus ('Dengue-like syndrome')...

We currently have limited knowledge of the involvement of long non-coding RNAs (lncRNAs) in normal cellular processes and pathologies. Here, we identify and characterize SNHG5 as a stable cytoplasmic lncRNA with up-regulated expression in colorectal cancer. Depletion of SNHG5 induces cell cycle arrest and apoptosis in vitro and limits tumour outgrowth in vivo, whereas SNHG5 overexpression counteracts oxaliplatin-induced apoptosis. Using an unbiased approach, we identify 121 transcript sites interacting with SNHG5 in the cytoplasm...

BACKGROUND: Age seemed to affect the interaction between coumarins and genotype in the acenocoumarol and phenprocoumon arm of the European pharmacogenetics of anticoagulant therapy (EU-PACT) trial. OBJECTIVES: To investigate the effect of genotype-guided dosing stratified by age and the potential factors causing a difference. PATIENTS/METHODS: Data from the acenocoumarol/phenprocoumon arm of the EU-PACT trial was used. The percentage of time below, above and in the therapeutic range (TTR) during the initial 12 weeks of therapy were compared between the genotype-guided group and the control group among younger (<75 years) and older (≥75 years) patients using independent t-test and adjust for sex, height, weight and co-medications using linear regression...

Taenia solium taeniosis/cysticercosis was declared eradicable by the International Task Force for Disease Eradication in 1993, but remains a neglected zoonosis. To assist in the attempt to regionally eliminate this parasite, we developed cystiSim, an agent-based model for T. solium transmission and control. The model was developed in R and available as an R package (http://cran.r-project.org/package=cystiSim). cystiSim was adapted to an observed setting using field data from Tanzania, but adaptable to other settings if necessary...

We conducted a systematic review regarding the efficacy and outcome of endovascular treatment of infected iliofemoral arterial pseudoaneurysms with covered stents. 35 cases were identified, including 5 own. 22 pseudoaneurysms were located in the femoral area and 13 in the iliac vessels. The most commonly reported complaints were pulsatile groin mass (40 %), sepsis (37.1 %), active bleeding (31.4 %), and groin infection with purulent discharge (17.1 %). S. aureus (65.7 %) and Streptococcus species (22.9 %) were the most common microbes isolated...

OBJECTIVE: Ospemifene, an estrogen receptor agonist/antagonist approved for the treatment of dyspareunia and vaginal dryness in postmenopausal women, has potential new indications as an immune modulator. The overall objective of the present series of preclinical studies was to evaluate the immunomodulatory activity of ospemifene in combination with a peptide cancer vaccine. METHODS: Immune regulating effects, mechanism of action and structure activity relationships of ospemifene and related compounds were evaluated by examining expression of T-cell activating cytokines in vitro, and antigen-specific immune response and cytotoxic T-lymphocyte activity in vivo...

Myoglobin (Mb) is known to react slowly with nitirite to form the green pigment by NO2(-) cordination to the heme Fe in the O-binding nitrito (O1NO2) mode and to the heme 2-vinyl position. Nitrite is a powerful oxidizing agent and a biological reservoir for NO that has been implicated in a variety of aerobic biological systems. Accordingly, it is important to elucidate the nature and variety of NO2(-) reaction mechanisms with Mb. We have performed principal component analysis (PCA, or essential dynamics) on Molecular Dynamics trajectories of all MbNO2 coordination states to resolve the most important motions in the protein at 298K...

Blastocyst implantation is a complex process requiring coordination of a dynamic sequence of embryo-uterine interactions. Blood vessels enter the uterus from the mesometrium, demarcating the uterus into mesometrial (M) and antimesometrial (AM) domains. Implantation occurs along the uterine longitudinal axis within specialized implantation chambers (crypts) that originate within the evaginations directed from the primary lumen toward the AM domain. The morphological orientation of crypts in rodent uteri was recognized more than a century ago, but the mechanism remained unknown...

Dry eye syndrome is an eye disorder affecting many people at an old age. Because dry eye syndrome is accelerated by aging, a useful approach to the prevention of this syndrome may be an intervention into the aging process. Previously, we showed that the mitochondria-targeted antioxidant SkQ1 delays manifestations of aging and inhibits the development of age-related diseases including dry eye syndrome. Nevertheless, the link between SkQ1's effects and its suppression of age-related changes in the lacrimal gland remains unclear...

OBJECTIVE: Absolute risk and risk factors for recurrence and ovarian serous carcinoma following ovarian serous borderline tumors (SBTs) is not well-established. METHODS: We included all women with SBTs in Denmark, 1978-2002. Diagnoses were confirmed by centralized pathology review and classified as atypical proliferative serous tumor (APST) or noninvasive low-grade serous carcinoma (LGSC). Implants were classified as noninvasive or invasive. Medical records were collected and reviewed, and follow-up was obtained...

The coordination of nitrite in myoglobin (Mb) has been characterized by resonance Raman spectroscopy and the frequencies of the nitrite bound to the heme Fe as well to the 2-vinyl have been computed by density functional theory (DFT) calculations. The DFT Natural Bond Orbital (NBO) analysis and the extensive isotope-labeling in the resonance Raman experiments indicate that NO2(-) (O1NO2) is bound to the heme Fe via O1. Based on the vibrational characterization of the reversible transition between low and high spin FeONO/2-nitrovinyl species, we suggest that the key step that triggers the spin-change is the increase of the proximal FeNHis93 bond length...

OBJECTIVES: Immigrants are typically healthier than the native-born population in the receiving country and also tend to be healthier than non-migrants in the countries of origin. This foreign-born health advantage has been referred to as the healthy immigrant effect (HIE). We examined evidence for the HIE in Canada. DESIGN: We employed a systematic search of the literature on immigration and health and identified 78 eligible studies. We used a narrative method to synthesize the HIE across different stages of the life-course and different health outcomes within each stage...

This study focuses on the relationship between content elements and mental-state language in narratives from twenty-seven children with autism (ASD), twelve children with language impairment (LI), and thirty typically developing children (TD). The groups did not differ on chronological age (10;6-14;0) and non-verbal cognitive skills, and the groups with ASD and TD did not differ on language measures. The children with ASD and LI had fewer content elements of the storyline than the TD children. Compared with the TD children, the children with ASD used fewer subordinate clauses about the characters' thoughts, and preferred talking about mental states as reported speech, especially in the form of direct speech...

OBJECTIVE: To identify an early response criterion for predicting ≥5% weight loss with liraglutide 3.0 mg at week 56 and to compare efficacy outcomes in early responders (ERs) and early nonresponders (ENRs). METHODS: Using pooled data from the SCALE Obesity and Prediabetes and SCALE Diabetes trials, weight loss of ≥4% at 16 weeks best predicted ≥5% weight loss after 56 weeks. Weight loss and changes in cardiometabolic risk factors and health-related quality of life were evaluated in ERs (≥4% weight loss at week 16) and ENRs (<4% weight loss at week 16) completing 56 weeks' treatment...
