103 Atypical Progressive Bulbar Palsy presenting with Dropped Head
Introduction: Typical amyotrophic lateral sclerosis (ALS) presents on neurological examination with specific signs of upper and lower motor neuron degeneration (Brooks et al, 1995), which can account for 85% of patients ... -
A 14‐ka record of dust input and phytoplankton regime changes in the subtropical NE pacific: oceanic and terrestrial processes linked by teleconnections at suborbital scales
We study shifts in phytoplankton proxies linked to terrigenous inputs and teleconnections in a core from Soledad Basin, Gulf of Ulloa, NW Mexico, spanning the end of the deglaciation and the Holocene. We used biogenic opal ... -
A 19-year old man with IgA vasculitis after vaccination
A 19-year-old patient who mistakenly received two doses of influenza vaccine 10 days before presentation, was admitted with malaise, weakness, and a purpuric non-blanching rash most prominent on the ankles followed by ... -
A cluster-randomized controlled trial to reduce diarrheal disease and dengue entomological risk factors in rural primary schools in Colombia
Background As many neglected tropical diseases are co-endemic and have common risk factors, integrated control can efficiently reduce disease burden and relieve resource-strained public health budgets. Diarrheal diseases ... -
A comparative analysis of the bronchodilatador response measured by impulse oscillometry and spirometry in asthmatic children living at high altitude
Although the assessment of a bronchodilator response (BDR) is a routine and important procedure when performing lung function tests, comparisons between spirometric and oscillometric BDRs in asthmatic children living at ... -
A comparison of cut points for measuring risk factors for adolescent substance use and antisocial behaviors in the U.S.and Colombia
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-02)As the identification and targeting of salient risk factors for adolescent substance use become more widely used globally, an essential question arises as to whether U.S.-based cut points in the distributions of these risk ... -
A comprehensive analysis of factors related to carmustine/bevacizumab response in recurrent glioblastoma
Purpose Patients with recurrent glioblastoma (rGBM) have a poor prognosis, with survival ranging from 25 to 40 weeks. Antiangiogenic agents are widely used, showing a variable response. In this study, we explored the efcacy ... -
A Computational Prototype for Electromagnetic Field Pollution Maps in Colombia
This work presents a first computational prototype for Electromagnetic Field (EMF) pollution visualization, as a geographic map for human exposure estimation to potentially harmful levels of electromagnetic radiation. The ... -
A conceptual definition of vocational rehabilitation based on the ICF: building a shared global model
Background The International Classification of Functioning, Disability and Health (ICF) is a conceptual framework and classification system by the World Health Organization (WHO) to understand functioning. The objective ... -
A consensus statement for trauma surgery capacity building in Latin America
(Springer Nature, 2021-01-30)Background Trauma is a significant public health problem in Latin America (LA), contributing to substantial death and disability in the region. Several LA countries have implemented trauma registries and injury surveillance ... -
A cross-cultural study of sex-typicality and averageness: Correlation between frontal and lateral measures of human faces.
Objectives Facial averageness and sexual dimorphism are extensively studied attractiveness markers, which are viewed as possible indicators of biological quality. Both are complex morphological traits, and both can be ... -
A cross-sectional survey of Aedes aegypti immature abundance in urban and rural household containers in central Colombia
Background Aedes aegypti, the major vector of dengue, breeds in domestic water containers. The development of immature mosquitoes in such containers is influenced by various environmental, ecological and socioeconomic ... -
A discrete epidemic model for bovine babesiosis disease and tick populations
In this paper, we provide and study a discrete model for the transmission of Babesiosis disease in bovine and tick populations. This model supposes a discretization of the continuous-time model developed by us previously. ... -
A Green's function approach to topological insulator junctions with magnetic and superconducting regions
This work presents a Green’s function approach, originally implemented in graphene with well-defined edges, to the surface of a strong 3D Topological Insulator (TI) with a sequence of proximitizedsuperconducting (S) and ... -
A landmark in the history of science: H. von foerster’s cybernetics of cybernetics (1974)
This paper presents and discusses an authentic landmark in the history of science, namely H. v. Foerster’s Cybernetics of Cybernetics, 1974, a most fundamental book based on the students’ notes. This is a book rarely ... -
A liaF codon deletion abolishes daptomycin bactericidal activity against vancomycin-resistant enterococcus faecalis
The genetic bases for antibiotic tolerance are obscure. Daptomycin (DAP) is a lipopeptide antibiotic with bactericidal activity against enterococci. Using time-kill assays, we provide evidence for the first time that a ... -
A liar deletion restores susceptibility to daptomycin and antimicrobial peptides in multidrug-resistant enterococcus faecalis
Daptomycin is a lipopeptide antibiotic that is used clinically against many gram-positive bacterial pathogens and is considered a key frontline bactericidal antibiotic to treat multidrug-resistant enterococci. Emergence ... -
A low-cost electrochemical biosensor platform for C-reactive protein detection
(Elsevier B.V., 2021)Antibiotic resistance is a worldwide problem aggravated by the overuse of prophylactic antibiotic therapies and lack of real-time biosensing equipment to differentiate viral from bacterial infections at the Point of Care ...
