 Donor Exposures in Recipients of Pooled Platelet Concentrates: a Case-Study in Arithmetic, Logic, "Expert Opinion", and the "Peer Review" Proc…
2013
Advocacy for single-donor (rather than pooled) platelets has been based on the absolute increase in the risk of transfusion-transmitted infections (TTIs) from pooled (rather than single-donor) platelets in the population of platelet transfusion recipients. A recent study published in a prestigious medical journal advocated for pooled (rather than single-donor) platelets based on the relative increase in the risk of TTIs from pooled (rather than single-donor) platelets in patients transfused with any blood component. If this policy recommendation for use of pooled (rather than single-donor) platelets were followed in the US, there would be an annual increase in the risk of TTIs by 15-20 reci…
Anomaly Detection in Dynamic Social Systems Using Weak Estimators
2009
Anomaly detection involves identifying observationsthat deviate from the normal behavior of a system. One ofthe ways to achieve this is by identifying the phenomena thatcharacterize “normal” observations. Subsequently, based on thecharacteristics of data learned from the “normal” observations,new observations are classified as being either “normal” or not.Most state-of-the-art approaches, especially those which belongto the family parameterized statistical schemes, work under theassumption that the underlying distributions of the observationsare stationary. That is, they assume that the distributions thatare learned during the training (or learning) phase, thoughunknown, are not time-varyin…
Context of validation of non-formal and informal learning in Spain: a comprehensive view
2019
The system of validation and accreditation of professional qualifications in Spain is offered as a certification opportunity, especially for vulnerable groups. The procedure is presented as an evaluative proposal that allows some inequalities associated with training and employment to be addressed. In this article we analyse whether this system really fosters social cohesion, considering the political situation that frames the procedure and the educational approach underlying it. The research methodology combines the documentary analysis and interviews with the application of the Delphi method. The most relevant results show that the socio-political context is favourable to competences accr…
Metro Manila’s Challenges: Flooding, Housing and Mobility
2014
Among the many challenges faced by MetroManila, the National Capital Region of the Philippines, three appear as the most pressing issues for the everydaylife of its citizens: housing, flooding and traffic. The rapid increase in population of the metropolitan area had led to a mushrooming of substandard housing and squatting, sometimes in danger areas such as waterways and transport lanes. In a tropical context of heavy monsoon rains and frequent typhoons, riverside slums impeding the flow of water appear as one of the reasons—not the only one—why Manila floods, when at the same time people are placed at high risk. Coupled with a lack of available space throughout the metropolis, the high po…
Prevalence and overlap of somatic symptom disorder, bodily distress syndrome and fibromyalgia syndrome in the German general population: A cross sect…
2020
Abstract Objective To study the prevalence and clinical characteristics of Somatic Symptom Disorder (SSD), Bodily Distress Syndrome (BDS) and fibromyalgia syndrome (FMS) and their overlap in the general German population. Methods A cross-sectional nationally representative population survey was performed. 2531 participants (mean age 48.8 ± 17.85 years, 53.3% women) completed the Somatic Symptom Scale SSS-8, the Bodily Distress Syndrome (BDS) 25 checklist, the Whiteley Index 7 (WI-7), the self-administered comorbidity questionnaire and the Michigan Body Map. Case definitions of SSD, BDS and FMS were assigned using established criteria. Results 4.5% of participants met the criteria of SSD (SS…
Myopia and Level of Education
2014
Purpose To analyze the association between myopia and educational level in an adult European cohort. Design Population-based cross-sectional study. Participants A cohort of the Gutenberg Health Study, including 4658 eligible enrollees between 35 and 74 years of age. Methods We applied a standardized protocol entailing a comprehensive questionnaire; thorough ophthalmic, general, cardiovascular, and psychological examinations; and laboratory tests, including genetic analyses. We documented achievement levels in school education and post-school professional education. The spherical equivalent (SE) was determined by noncycloplegic autorefractometry. We fitted mixed linear models including age, …
Design of virtual environments for the treatment of agoraphobia: Inclusion of culturally relevant elements for the population of the Dominican Republ…
2020
Abstract Virtual Reality is a powerful tool for the treatment of agoraphobia. However, how effective is the use of these scenarios when they do not resemble the sociocultural context? Literature suggests that the inclusion of culturally relevant elements increases the ecological validity and transferability of learning since it reduces the gap between the virtual and real context. Unfortunately, in Latin America, the development of virtual environments is incipient, and the use of generic virtual environments is commonplace. The objective of this study was to develop virtual environments that include elements that are culturally relevant to the population of the Dominican Republic. Three hu…
Temporal Distribution of Gastropods In Rocky Intertidal Area In North Manokwari, West Papua
2019
Gastropods is an important organism that commonly found inhabiting the rocky intertidal area. Distribution pattern of this species is influenced by various factors such as population history, microhabitat, predation and a complex interactions between oceanographic dynamics and ecological features. This study aims to compare the temporal distribution pattern of gastropods at two different rocky intertidal area. This research was conducted at the rocky intertidal area of Amban and Nuni, North Manokwari District, West Papua. Data collection was performed during the daylight and night in April and June 2012 using systematic sampling method. The results showed that both physical and chemical fac…
V?9V?2 T lymphocytes activation in osteoporotic patients treated with bisphosphonates
2014
Treatment with bisphosphonates induces differentiation and activation of Vγ9Vδ2 T lymphocytes obtained from peripheral blood showing also an antitumoral effect in both in vitro and in vivo models. Aim of the present study was to determine in vivo the effect of BPs treatment in patients affected with osteoporosis on Vγ9Vδ2 T lymphocytes. We have studied Vγ9Vδ2 T lymphocytes expansion and differentiation from PBMC obtained from osteoporotic patients treated with one of the following bisphosphonates zoledronate, alendronate, neridronate or risedronate. We have found that zoledronic acid, followed by alendronate was the most effective on reducing CM population (100%) and increasing TEM and TEMR…
Shared feature representations of LiDAR and optical images: Trading sparsity for semantic discrimination
2015
This paper studies the level of complementary information conveyed by extremely high resolution LiDAR and optical images. We pursue this goal following an indirect approach via unsupervised spatial-spectral feature extraction. We used a recently presented unsupervised convolutional neural network trained to enforce both population and lifetime spar-sity in the feature representation. We derived independent and joint feature representations, and analyzed the sparsity scores and the discriminative power. Interestingly, the obtained results revealed that the RGB+LiDAR representation is no longer sparse, and the derived basis functions merge color and elevation yielding a set of more expressive…
