BACKGROUND: To derive and validate a predictive scoring tool (RHINO-ooze score) with good sensitivity and specificity in identifying patients with epistaxis at high risk of 30 day readmission and to enable risk stratification for possible definitive intervention. METHODS: Using medical databases, we searched for factors influencing recurrent epistaxis. The information ascertained together with our analysis of retrospective data on patients admitted with epistaxis between October 2013 and September 2014, was used as the derivation cohort to develop the predictive scoring model (RHINO-ooze score)...

Mucormycosis is an emerging infectious disease with high rates of associated mortality and morbidity. Little is known about the characteristics of mucormycosis or entomophthoromycosis occurring in Mexico. A search strategy was performed of literature published in journals found in available databases and theses published online at Universidad Nacional Autónoma de México (UNAM) library website reporting clinical cases or clinical case series of mucormycosis and entomophthoromycosis occurring in Mexico between 1982 and 2016...

Piwi-Interacting RNAs (piRNAs) are central components of the piRNA pathway, which directs transposon silencing and guarantees genome integrity in the germ cells of several metazoans. In Drosophila, piRNAs are produced from discrete regions of the genome termed piRNA clusters, whose expression relies on the RDC complex comprised of the core proteins Rhino, Deadlock and Cutoff. To date, the RDC complex has been exclusively implicated in the regulation of the piRNA loci. Here we further elucidate the function of Cutoff and the RDC complex by performing genome-wide ChIP-seq and RNA-seq assays in the Drosophila germline and analyzing these data together with other publicly available data sets...

During spatial navigation, neural activity in the hippocampus and the medial entorhinal cortex (MEC) is correlated to navigational variables such as location, head direction, speed, and proximity to boundaries. These activity patterns are thought to provide a map-like representation of physical space. However, the hippocampal-entorhinal circuit is involved not only in spatial navigation, but also in a variety of memory-guided behaviours. The relationship between this general function and the specialized spatial activity patterns is unclear...

Infections caused by filamentous fungi represent a major burden in the ICU. Invasive aspergillosis is emerging in non-neutropenic individuals with predisposing conditions, e.g. corticosteroid treatment, chronic obstructive pulmonary disease, liver cirrhosis, solid organ cancer, HIV infection and transplantation. Diagnosis is challenging because the signs and symptoms are non-specific, and initiation of additional diagnostic examinations is often delayed because clinical suspicion is low. Isolation of an Aspergillus species from the respiratory tract in critically ill patients, and tests such as serum galactomannan, bronchoalveolar lavage 1-3-β-d-glucan and specific PCR should be interpreted with caution...

Climate change and humans are proposed as the two key drivers of total extinction of many large mammals in the Late Pleistocene and Early Holocene, but disentangling their relative roles remains challenging owing to a lack of quantitative evaluation of human impact and climate-driven distribution changes on the extinctions of these large mammals in a continuous temporal-spatial dimension. Here, our analyses showed that temperature change had significant effects on mammoth (genus Mammuthus), rhinoceros (Rhinocerotidae), horse (Equidae) and deer (Cervidae)...

BACKGROUND: Ancient protein sequences are increasingly used to elucidate the phylogenetic relationships between extinct and extant mammalian taxa. Here, we apply these recent developments to Middle Pleistocene bone specimens of the rhinoceros genus Stephanorhinus. No biomolecular sequence data is currently available for this genus, leaving phylogenetic hypotheses on its evolutionary relationships to extant and extinct rhinoceroses untested. Furthermore, recent phylogenies based on Rhinocerotidae (partial or complete) mitochondrial DNA sequences differ in the placement of the Sumatran rhinoceros (Dicerorhinus sumatrensis)...

INTRODUCTION: Psoriatic patients on tumor necrosis factor alpha inhibitors (TNFi) may be at increased risk for upper respiratory tract infections, including chronic rhino-sinusitis (CRS). Rarely, CRS can progress to orbital cellulitis (OC), an emergent ophthalmic complication wherein respiratory flora from paranasal sinus disease intrude the retro-orbital space. MATERIALS AND METHODS: Single case report. RESULTS: We report the first case, to our knowledge, of an invasive sinusitis that rapidly evolved into OC in a patient receiving adalimumab treatment for plaque psoriasis and psoriatic arthritis...

Self-directed learning is associated with knowledge and performance improvements, increased identification and amelioration of knowledge gaps, and heightened critical appraisal of available evidence. We developed and implemented a decision support system that could support self-directed learning for anesthesia residents by soliciting resident input in case selection. We hypothesized that residents would utilize this system to request complex cases, and that more advanced residents would request more complex cases...

Mucormycosis commonly affects immunocompromised individuals with defects in neutrophil function or count. Diabetes mellitus is an important risk factor due to impair innate and acquired immunity for mucormycosis, with rhino-orbital-cerebral involvement as a common presentation. Pulmonary mucormycosis (PM) although a rare presentation in diabetic patients but is associated with high mortality and morbidity. An early diagnosis of PM is difficult, due to rarity of the disease and clinical and radiological features resembling tuberculosis (TB) which is common in Pakistan...
