Elevated plasma levels of lipoprotein(a) (Lp(a)) are associated with increased cardiovascular risk in several clinical studies. However, there is a lack of data supporting a positive association between elevated Lp(a) levels and venous thromboembolism (VTE). Thus, we conducted a systematic review of the literature to better clarify its role as a risk factor for VTE. Medline and the Embase (up to May 2015) electronic databases were used to identify potentially eligible studies. Studies measuring Lp(a) values in adult patients with deep vein thrombosis and/or pulmonary embolism and in a population of patients without a VTE were selected...

Large multimolecular complexes of heparin with positively charged proteins such as platelet factor 4 (PF4) or protamine can initiate immune responses associated with heparin use in patients, including the most significant adverse event, heparin-induced thrombocytopenia (HIT). Current evidence suggests that platelet-activating antibodies that recognize large multi-molecular complexes (300-700kDa) of PF4 bound to heparin cause HIT [1] and in very rare cases anti-protamine-heparin antibodies can induce thrombocytopenia [2]...

Infants learn to use auditory and visual information to organize the sensory world into identifiable objects with particular locations. Here we use a behavioural method to examine infants' use of harmonicity cues to auditory object perception in a multisensory context. Sounds emitted by different objects sum in the air and the auditory system must figure out which parts of the complex waveform belong to different sources (auditory objects). One important cue to this source separation is that complex tones with pitch typically contain a fundamental frequency and harmonics at integer multiples of the fundamental...

The presence of major arbovirus vector species, climate change that promotes the expansion and increase of their populations, and potential animal reservoirs mean that vector-borne diseases represent a significant health risk for Mallorca's inhabitants. Microbiological monitoring of circulating arboviruses, particularly flaviviruses causing encephalitis, was initiated using domestic horses from localities near wetlands as "sentinel" hosts. A total of 291 blood samples were taken from 172 horses between 2011 and 2012, using paired samples to highlight seroconversion events...

BACKGROUND: Aquatic therapy has several proposed benefits for people with lymphedema. A systematic review of the evidence for aquatic therapy in lymphedema management has not been conducted. METHOD AND RESULTS: Systematic review and meta-analysis were conducted. Five electronic databases were searched to identify randomized controlled trials (RCTs) of people with lymphedema, which compared aquatic therapy with other lymphedema interventions. Qualitative analysis was undertaken where quantitative analysis was not possible...

Blastomycosis elicits a pyogranulomatous inflammatory response, which involves a prominent recruitment of neutrophils to the site of infection. While neutrophils are efficiently recruited to the site of infection, this event is paradoxically coupled with the host's inability to control infection by Blastomyces dermatitidis, the causative agent. The mechanisms underlying this characteristic pyogranulomatous response and inability of neutrophils to kill the yeast are poorly understood. We recently reported that the fungal protease DppIVA promotes B...

Frailty models have a prominent place in survival analysis to model univariate and multivariate time-to-event data, often complicated by the presence of different types of censoring. In recent years, frailty modeling gained popularity in infectious disease epidemiology to quantify unobserved heterogeneity using Type I interval-censored serological data or current status data. In a multivariate setting, frailty models prove useful to assess the association between infection times related to multiple distinct infections acquired by the same individual...

BACKGROUND: Treatments for head and neck squamous cell carcinoma (HNSCC) are associated with toxicities that lead to emergency department presentation. METHODS: We utilized data from an ongoing prospective cohort of newly diagnosed, previously untreated patients (N = 298) with HNSCC to evaluate the association between clinical and epidemiologic factors and risk for and frequency of emergency department presentation. Time to event was calculated from the date of treatment initiation to emergency department presentation, date of death, or current date...

Importance: As perinatally human immunodeficiency virus-infected youth (PHIVY) in the United States grow older and more treatment experienced, clinicians need updated information about the association of age, CD4 cell count, viral load (VL), and antiretroviral (ARV) drug use with risk of opportunistic infections, key clinical events, and mortality to understand patient risks and improve care. Objective: To examine the incidence or first occurrence during follow-up of key clinical events (including Centers for Disease Control and Prevention stage B [CDC-B] and stage C [CDC-C] events) and mortality among PHIVY stratified by age, CD4 cell count, and VL and ARV status...

Azobenzene-containing smart materials are able to transform the energy of light into directional mechanical stress. We develop a theory of time-dependent light-induced ordering and deformation in azobenzene materials starting from the kinetic equations of photoisomerization. The liquid crystalline (LC) interactions between rod-like trans-isomers are taken into account. Angular selectivity of the photoisomerization known as an "angular hole burning" or the Weigert effect leads to the light-induced ordering and deformation of the azobenzene materials...

Gender differences in feedback processing have been observed among adolescents and adults through event-related potentials. However, information on whether and how this feedback processing is affected by feedback valence, feedback type, and individual sensitivity in reward/punishment among children remains minimal. In this study, we used a guessing game task coupled with electroencephalography to investigate gender differences in feedback processing, in which feedback to reward and punishment was presented in the context of monetary and social conditions...

Schinzel-Giedion syndrome (SGS) is a rare developmental disorder characterized by multiple malformations, severe neurological alterations and increased risk of malignancy. SGS is caused by de novo germline mutations clustering to a 12bp hotspot in exon 4 of SETBP1. Mutations in this hotspot disrupt a degron, a signal for the regulation of protein degradation, and lead to the accumulation of SETBP1 protein. Overlapping SETBP1 hotspot mutations have been observed recurrently as somatic events in leukemia. We collected clinical information of 47 SGS patients (including 26 novel cases) with germline SETBP1 mutations and of four individuals with a milder phenotype caused by de novo germline mutations adjacent to the SETBP1 hotspot...

A number of human activities exhibit a bursty pattern, namely periods of very high activity that are followed by rest periods. Records of these processes generate time series of events whose inter-event times follow a probability distribution that displays a fat tail. The grounds for such phenomenon are not yet clearly understood. In the present work we use the freely available Wikipedia's editing records to unravel some features of this phenomenon. We show that even though the probability to start editing is conditioned by the circadian 24 hour cycle, the conditional probability for the time interval between successive edits at a given time of the day is independent from the latter...

The diverse migratory modes displayed by different cell types are generally believed to be idiosyncratic. Here we show that the migratory behaviour of Dictyostelium was switched from amoeboid to keratocyte-like and oscillatory modes by synthetically decreasing phosphatidylinositol-4,5-bisphosphate levels or increasing Ras/Rap-related activities. The perturbations at these key nodes of an excitable signal transduction network initiated a causal chain of events: the threshold for network activation was lowered, the speed and range of propagating waves of signal transduction activity increased, actin-driven cellular protrusions expanded and, consequently, the cell migratory mode transitions ensued...
