Identification of preliminary core outcome domains for communication about childhood vaccination: An online Delphi survey.

Vaccine

October 2018

Centre for Health Communication and Participation, Health Sciences 2, School of Psychology and Public Health, La Trobe University, Bundoora, Melbourne, VIC 3086, Australia. Electronic address:

Background: Communication interventions for childhood vaccination are promising strategies to address vaccine hesitancy, but current research is limited by the outcomes measured. Most studies measure only vaccination-related outcomes, with minimal consideration of vaccine hesitancy-relevant intermediate outcomes. This impedes understanding of which interventions or elements are effective.

Introduction: Clinical onset of chronic obstructive pulmonary disease (COPD) is the point at which the disease is first identifiable by physicians. It is a poorly defined stage which seems to include both mild spirometric and non-spirometric disease, and could be described as early grade COPD, for practical purposes. While dyspnoea; chronic bronchitis and CT imaging evidence of emphysema and airway disease may be present very early, the lone significance of dyspnoea, the most relevant symptom in COPD in identifying these individuals, has been scarcely assessed.

Ultrasound Morphology of Polycaprolactone Filler.

J Ultrasound Med

December 2017

Department of Dermatology, Faculty of Medicine, Pontifical Catholic University of Chile, Santiago, Chile.

Nowadays, cosmetic fillers are widely used and the reports of complications are rising. Therefore, the possibility to detect and identify noninvasively new fillers can provide a potent tool for managing complications. The objective of this study was to assess the ultrasound morphology of polycaprolactone.

Background: Glucose-derived metabolites may alter the structure and biologic properties of important proteins in periodontium, such as collagens. As a consequence, it is possible that collagen-binding cells may change their phenotypic traits. Although the glucose-derived product methylglyoxal (MGO) has been detected in periodontal lesions, the precise effect of collagen glycation on gingival connective tissue biology is not fully understood.

The purpose of this study was to explore resilience processes in Palestinian refugee families living under Israeli occupation for multiple generations. Qualitative methods, critical postcolonial theories, and community-based research approaches were used to examine intergenerational protective practices and to contribute to reconceptualizations of resilience from indigenous perspectives. First, the researcher developed a collaborative partnership with a nongovernmental organization (NGO) in a UN refugee camp in the occupied West Bank.

Background: Communication can be used to generate demand for vaccination or address vaccine hesitancy, and is crucial to successful childhood vaccination programmes. Research efforts have primarily focused on communication for routine vaccination. However, vaccination campaigns, particularly in low- or middle-income countries (LMICs), also use communication in diverse ways.

Pannexin channels increase propidium iodide permeability in frozen-thawed dog spermatozoa.

Reprod Fertil Dev

October 2017

Laboratory of Animal Reproduction, Faculty of Veterinary Sciences, University of Chile, Casilla 2, Correo 14, La Granja, Santiago, Chile.

Pannexins (Panx) are proteins that form functional single membrane channels, but they have not yet been described in dogs. The aim of the present study was to detect Panx1, Panx2 and Panx3 in frozen-thawed dog spermatozoa using flow cytometry and immunofluorescence analyses, evaluating the relationship of these proteins with propidium iodide (PI) in frozen-thawed spermatozoa. Fresh and frozen-thawed dog spermatozoa from eight dogs were preincubated with 3μM PI with or without 15μM carbenoxolone (CBX) or 1mM probenecid (PBD), two Panx channel inhibitors, and then incubated with rabbit anti-Panx1, anti-Panx2 and anti-Panx3 antibodies (1:200).

Expansion of white adipose tissue induce insufficient vascularization, driving hypoxia and low-grade inflammation. Resident preadipocytes are thought to be involved. We evaluated the effects of hypoxia over preadipocytes and adipocytes, to determine which cellular type impacts the most over macrophages activation.

Background And Objectives: Protein-energy and micronutrient malnutrition are global public health problems which, when not prevented and severe, require medical management by clinicians with nutrition expertise, preferably as a collectively skilled team, especially when disease-related. This study aimed to investigate barriers and facilitators of clinical nutrition services (CNS), especially the use of oral, enteral (EN) and parenteral (PN) nutrition in institutional and home settings.

Methods And Study Design: An international survey was performed between January and December 2014 in twenty-six countries from all continents.

Article Synopsis
  • Two cardiac risk prediction models were developed for 182 countries, one requiring lab measurements and the other based solely on office measurements.
  • The lab-based model incorporates factors like age, sex, smoking, and cholesterol, while the non-lab model substitutes diabetes and cholesterol with BMI.
  • Analysis shows that HICs generally have lower predicted risks compared to LMICs, with the highest risks observed in central and southeast Asia and eastern Europe.

May 2018

Advanced Center for Chronic Diseases (ACCDiS), Faculty of Chemical and Pharmaceutical Sciences, University of Chile, Olivos 1007, Santiago 8380492. Chile.

Cardiovascular disease is the leading cause of death worldwide. The heart is susceptible to pathologies that impact the myocardium directly, such as myocardial infarction and consequent heart failure, as well as conditions with indirect cardiac effects, such as cancer treatment-related cardiotoxicity. As the contractile cells of the heart, cardiomyocytes are essential for normal cardiac function.

Potential of an outranking multi-criteria approach to support the participatory assessment of land management actions.

J Environ Manage

June 2017

Office of Arid Lands Studies, School of Natural Resources and the Environment, University of Arizona, USA; Department of Ecology, University of Alicante, Spain. Electronic address:

We evaluated the potential of an outranking Multi-Criteria Decision Analysis approach for assisting in the participatory assessment of dryland management actions implemented in the San Simon watershed, in southeastern Arizona, USA. We compared an outranking-facilitated assessment of actions with a simple and direct (baseline) ranking of the same actions by the participating stakeholders in terms of: 1) internal homogeneity of each assessment approach, (2) similarity of individual assessments between methods, and (3) effects of the use of implicit/explicit assessment criteria. The actions assessed combined various management approaches, including livestock management (rotation, resting), vegetation management (grass seeding, brush control), and hydraulic structures (dams, dykes).

Background: In the past decade, the bifactor model of attention-deficit/hyperactivity disorder (ADHD) has been extensively researched. This model consists of an ADHD general dimension and two specific factors: inattention and hyperactivity/impulsivity. All studies conclude that the bifactor is superior to the traditional two-correlated factors model, according to the fit obtained by factor analysis.

Background: The treatment of chronic hypersensitivity pneumonitis (cHP) often includes systemic oral corticosteroids, but the optimal pharmacologic management remains unclear. The morbidity associated with prednisone has motivated the search for alternative therapies. We aimed to determine the effect of treatment with mycophenolate mofetil (MMF) or azathioprine (AZA) on lung function in patients with cHP.

Network-Level Dysconnectivity in Drug-Naïve First-Episode Psychosis: Dissociating Transdiagnostic and Diagnosis-Specific Alterations.

Neuropsychopharmacology

March 2017

Department of Psychosis Studies, Institute of Psychiatry, Psychology and Neuroscience, King's College London, London, UK.

The neuroimaging literature provides compelling evidence for functional dysconnectivity in people with psychosis. However, it is likely that at least some of the observed alterations represent secondary effects of illness chronicity and/or antipsychotic medication. In addition, the extent to which these alterations are specific to psychosis or represent a transdiagnostic feature of psychiatric illness remains unclear.

Ultrasound-Guided Cervical Medial Branch Radiofrequency Neurotomy: Can Multitined Deployment Cannulae Be the Solution?

Reg Anesth Pain Med

October 2017
