Developing an Open-Source, User-Friendly, OWASP-Compliant Architecture for Healthcare Web Application Testing.

Nowadays, web applications are fundamental in the healthcare sector. However, with the widespread use of this technology, risks related to cybersecurity attacks also increase. To mitigate this phenomenon, every 3-4 years, the nonprofit foundation Open Worldwide Application Security Project (OWASP) compiles a top 10 ranking of the most critical web application security risks. Along with the top 10 Web Application Security Risks, OWASP also provides the Web Security Testing Guide, which offers comprehensive guidelines for conducting security tests. This guide includes suggestions for specific tools to use when performing different tests, among other valuable insights. However, the use of these recommended tools can be costly and can require advanced technical skills and a deep understanding of security best practices and web technologies. In addition, since the OWASP work on web security is generic, it would be useful to restrict and adapt it to the healthcare area. This would help in reducing the overhead when dealing with the needed tools. The goal of this study is to make web application security assessment in healthcare more accessible by developing tools that simplify the process and makes it user- friendly. Before developing such tools, an in-depth feasibility study must be conducted to verify the existence of open-source libraries to carry out the necessary testing procedures. It will be also necessary to identify how tools could be simplified and enhanced when focusing on healthcare.

Providing Provenance in eHealth.

eHealth data can be generated by different health professionals. Documenting and storing the provenance of medical data will help in providing patients and medical institutions with trustable and traceable information regarding medical procedures and their results. The use of a modular architecture like HIPAMS allows covering different eHealth information representation formats as well as providing protection mechanisms and access control.

Use of Beacon v2 for Improving Genomics Based Research in a Clinical Setting.

GA4GH has proposed the Beacon architecture as an interface to retrieve genomic information which also protects the privacy of the individuals. In this paper, we propose to adapt the Beacon Reference Implementation to the use case of a study comparing the susceptibility to the carcinogenic effects of tobacco. This analysis compares the germline of heavy smokers who have either never developed lung cancer or, on the contrary, have developed it at a young age. To adapt the Beacon Reference Implementation to the use case, we have added filtering capabilities and a new grouping of information allowing to retrieve the data by affected gene.

Speech Reception in Young Children with Autism Is Selectively Indexed by a Neural Oscillation Coupling Anomaly.

Communication difficulties are one of the core criteria in diagnosing autism spectrum disorder (ASD), and are often characterized by speech reception difficulties, whose biological underpinnings are not yet identified. This deficit could denote atypical neuronal ensemble activity, as reflected by neural oscillations. Atypical cross-frequency oscillation coupling, in particular, could disrupt the joint tracking and prediction of dynamic acoustic stimuli, a dual process that is essential for speech comprehension. Whether such oscillatory anomalies already exist in very young children with ASD, and with what specificity they relate to individual language reception capacity is unknown. We collected neural activity data using electroencephalography (EEG) in 64 very young children with and without ASD (mean age 3; 17 females, 47 males) while they were exposed to naturalistic-continuous speech. EEG power of frequency bands typically associated with phrase-level chunking (δ, 1-3 Hz), phonemic encoding (low-γ, 25-35 Hz), and top-down control (ß, 12-20 Hz) were markedly reduced in ASD relative to typically developing (TD) children. Speech neural tracking by δ and θ (4-8 Hz) oscillations was also weaker in ASD compared with TD children. After controlling gaze-pattern differences, we found that the classical θ/γ coupling was replaced by an atypical ß/γ coupling in children with ASD. This anomaly was the single most specific predictor of individual speech reception difficulties in ASD children. These findings suggest that early interventions (e.g., neurostimulation) targeting the disruption of ß/γ coupling and the upregulation of θ/γ coupling could improve speech processing coordination in young children with ASD and help them engage in oral interactions.SIGNIFICANCE STATEMENT Very young children already present marked alterations of neural oscillatory activity in response to natural speech at the time of autism spectrum disorder (ASD) diagnosis. Hierarchical processing of phonemic-range and syllabic-range information (θ/γ coupling) is disrupted in ASD children. Abnormal bottom-up (low-γ) and top-down (low-ß) coordination specifically predicts speech reception deficits in very young ASD children, and no other cognitive deficit.

An Architecture for Providing Personalized Digital Health.

Patients need mechanisms to integrate health information coming from different sources, including personal devices. This would lead to Personalized Digital Health (PDH). HIPAMS (Health Information Protection And Management System) is a modular and interoperable secure architecture that helps in achieving this objective and building a Framework for PDH. The paper presents HIPAMS and how it supports PDH.

Fitting Multiplet Simulations to L-Edge XAS Spectra of Transition-Metal Complexes Using an Adaptive Grid Algorithm.

A new methodology based on an adaptive grid algorithm followed by an analysis of the ground state from the fit parameters is presented to analyze and interpret experimental XAS L2,3-edge data. The fitting method is tested first in a series of multiplet calculations for d0-d7 systems and for which the solution is known. In most cases, the algorithm is able to find the solution, except for a mixed-spin Co2+ Oh complex, where it instead revealed a correlation between the crystal field and the electron repulsion parameters near spin-crossover transition points. Furthermore, the results for the fitting of previously published experimental data sets on CaO, CaF2, MnO, LiMnO2, and Mn2O3 are presented and their solution discussed. The presented methodology has allowed the evaluation of the Jahn-Teller distortion in LiMnO2, which is consistent with the observed implications in the development of batteries, which use this material. Moreover, a follow-up analysis of the ground state in Mn2O3 has demonstrated an unusual ground state for the highly distorted site which would be impossible to optimize in a perfect octahedral environment. Ultimately, the presented methodology can be used in the analysis of X-ray absorption spectroscopy data measured at the L2,3-edge for a large number of materials and molecular complexes of first-row transition metals and can be expanded to the analysis of other X-ray spectroscopic data in future studies.

Sexual and gender minority health in Chile: findings from the 2016-2017 Health Survey.

OBJECTIVE: To expose visibility of the health concerns of sexual and gender minority groups in Chile, as well as to provide a platform to advocate for policies that support the health and well-being of sexual and gender minority people in the country. METHODS: The health conditions and risk factors of participants identified as sexual and gender minority were compared to those identified as cisgender heterosexual using data from the 2016-2017 National Health Survey. RESULTS: Despite reporting higher self-rated health than heterosexual men, gay men had a higher risk of lifetime diagnosis of sexually transmitted infections. Compared to heterosexual women, the prevalence of depression was higher among bisexual women, who were also less likely to have been tested for HIV. Moreover, transgender participants were more likely to report depression and worse self-rated health than cisgender heterosexual participants. CONCLUSION: Small sample sizes of sexual and gender minority subgroups might have obscured some differences that would have been observable in larger samples. Despite this, we found statistically significant sexual and/or gender identity differences in several health areas, especially mental, sexual, and overall health.

FAIR Aspects of a Health Information Protection and Management System.

BACKGROUND: Privacy management is a key issue when dealing with storage and distribution of health information. However, FAIR (Findability, Accessibility, Interoperability, and Reusability) principles when sharing information are in increasing demand in several organizations, especially for information generated in public-funded research projects. OBJECTIVES: The two main objectives of the presented work are the definition of a secure and interoperable modular architecture to manage different kinds of medical content (xIPAMS [x, for Any kind of content, Information Protection And Management System] and HIPAMS [Health Information Protection And Management System]), and the application of FAIR principles to that architecture in such a way that privacy and security are compatible with FAIR. METHODS: We propose the concept of xIPAMS as a modular architecture, following standards for interoperability, which defines mechanisms for privacy, protection, storage, search, and access to health-related information. RESULTS: xIPAMS provides FAIR principles and preserves patient's privacy. For each module, we identify how FAIR principles apply. CONCLUSIONS: We have analyzed how xIPAMS, and in particular HIPAMS (Health content), support the FAIR principles focusing on security and privacy. We have identified the FAIR principles supported by the different xIPAMS modules, concluding that the four principles are supported. Our analysis has also considered a possible implementation based on the concept of DACS (Document Access and Communication System), a system storing medical documents in a private and secure way. In addition, we have analyzed security aspects of the FAIRification process and how they are provided by xIPAMS modules.

Provenance and Dynamic Consents for the Management of Medical Data.

Medical data describe patient health information, both in healthy and disease conditions. In any case, health institutions need to ask for patient consent in order to provide their services. Patients usually give consent on a one-time basis, for a specific usage. Afterwards, if medical data usage is research, original patient consent does not apply and further consents should be required. On the other hand, provenance of medical data to verify the origin of health procedures is desirable, as digital health is increasing. We propose HIPAMS modular architecture to provide both provenance and dynamic consents for medical data as described in this paper.

Implementation of Privacy and Security for a Genomic Information System Based on Standards.

Genomic information is a very sensitive type of digital information as it not only applies to a person, but also to close relatives. Therefore, privacy provision is key to protecting genomic information from unauthorized access. It is worth noting that most of the current genomic information formats do not provide specific mechanisms by which to secure the stored information. In order to solve, among other things, the privacy provision issue, we proposed the GIPAMS (Genomic Information Protection And Management System) modular architecture, which is based on the use of standards such as ISO/IEC 23092 and a few GA4GH (Global Alliance for Genomics and Health) initiatives. Some of the GIPAMS modules have already been implemented, mainly based on ISO/IEC 23092 features, and we are conducting work on the complete version of the architecture, and other standards are also considered. One of the objectives of GIPAMS is to enable the management of different formats of genomic information in a unique and interoperable way, providing privacy and security for formats that do not currently support them.

¿Es la homofobía un concepto necesario? Análisis histórico-conceptual e implicancias psicosociales para la comunidad LGBTIQ / Is homophobia a necessary concept? Historical-conceptual analysis and psychosocial implications for the LGBTIQ community

El concepto de homofobia ha sido relevante para el estudio de las minorías sexuales y ha tenido un impacto positivo en el desarrollo de teorías académicas y efectos en la visibilidad de la homosexualidad. A pesar de esto, su reduccionismo al campo exclusivo de la homosexualidad masculina y la sobregeneralización de su uso significa la reproducción de asimetrías de poder que invisibilizan a otros sub-grupos de las minorías sexo-genéricas. Entre estos otros grupos están lesbianas, trans, queer, intersex, así como también, invisibiliza factores interseccionales como raza, etnia, género, clase. Es por esto, que este artículo tiene como intención realizar un análisis crítico del surgimiento del concepto de homofobia, sus implicancias y aportes para el campo de la psicología y las ciencias sociales en general

The concept of homophobia has been relevant to the study of sexual minorities and has had a positive impact on theory development academic, as well as effects on the visibility of the homosexuality. Despite this, his reductionism to the exclusive field of homosexuality masculine and the overgeneralization of its use means the reproduction of power asymmetries that make other minority sub-groups invisible sex-generic. Among these other groups are lesbian, trans, queer, intersex, as well as intersectional factors, such as race, ethnicity, gender, class. This is why this article intends to carry out a critical analysis of the emergence of the concept of homophobia, its implications and contributions for the field of psychology and the social sciences in general

Peptides recovery from egg yolk lipovitellins by ultrafiltration and their in silico bioactivity analysis.

The lipoproteins that remain after the extraction of phosvitin from the egg yolk granular fraction possess low industrial applicability. In this study, these lipoproteins were hydrolysed using trypsin, and the bioactivity of the resulting peptides was assessed by in silico analysis. In addition, in order to isolate the most valuable previously detected peptides, their transmission through a polyethersulfone (PES) membrane and a stabilised cellulose (SC) based membrane was also evaluated at several pHs. A pH of 4.0 gave the highest observed transmission of peptides through both membranes for every peptide identified in the permeate streams. Regarding the PES membrane, six peptide sequences detected in the permeate were predicted to be antihypertensive, although only one of them showed a bioactivity score higher than 0.5 according to Peptide Ranker. When the SC membrane was assessed, five peptides with a bioactivity score higher than 0.5 were detected in the permeate streams and eight peptides were predicted as antihypertensive. The in silico analysis performed showed that K.VQWGIIPSWIK.K was the most promising antihypertensive peptide found in the permeates.

Implementation of Privacy and Security for a Genomic Information System.

Genomic information is key for the implementation of real personalized medicine. Nevertheless, access to this kind of information must be controlled because of its high privacy and security requirements. Several genomic information formats exist, although we have started from MPEG-G as it includes metadata and protection mechanisms since its inception and provides a hierarchical structure to organize the information contained. The proposed GIPAMS modular architecture provides a secure and controlled access to genomic information, which may help on improving personalized medicine as described in this paper.

FAIR Aspects of a Genomic Information Protection and Management System.

To handle genomic information while supporting FAIR principles, we present GIPAMS, a modular architecture. GIPAMS provides security and privacy to manage genomic information by means of several independent services and modules that interact among them in an orchestrated way. The paper analyzes how some security and privacy aspects of the FAIRification process are covered by the GIPAMS platform.

Millisecond timescale reactions observed via X-ray spectroscopy in a 3D microfabricated fused silica mixer.

Determination of electronic structures during chemical reactions remains challenging in studies which involve reactions in the millisecond timescale, toxic chemicals, and/or anaerobic conditions. In this study, a three-dimensionally (3D) microfabricated microfluidic mixer platform that is compatible with time-resolved X-ray absorption and emission spectroscopy (XAS and XES, respectively) is presented. This platform, to initiate reactions and study their progression, mixes a high flow rate (0.50-1.5 ml min-1) sheath stream with a low-flow-rate (5-90 µl min-1) sample stream within a monolithic fused silica chip. The chip geometry enables hydrodynamic focusing of the sample stream in 3D and sample widths as small as 5 µm. The chip is also connected to a polyimide capillary downstream to enable sample stream deceleration, expansion, and X-ray detection. In this capillary, sample widths of 50 µm are demonstrated. Further, convection-diffusion-reaction models of the mixer are presented. The models are experimentally validated using confocal epifluorescence microscopy and XAS/XES measurements of a ferricyanide and ascorbic acid reaction. The models additionally enable prediction of the residence time and residence time uncertainty of reactive species as well as mixing times. Residence times (from initiation of mixing to the point of X-ray detection) during sample stream expansion as small as 2.1 ± 0.3 ms are also demonstrated. Importantly, an exploration of the mixer operational space reveals a theoretical minimum mixing time of 0.91 ms. The proposed platform is applicable to the determination of the electronic structure of conventionally inaccessible reaction intermediates.

Sociodemographic Characteristics, Gender Identification, and Gender Affirmation Pathways in Transgender People: A Survey Study in Chile.

Understanding the internal diversity of transgender communities is essential for developing optimal, inclusive policies and service provision. To date, research on this topic remains scarce in Chile. We conducted a survey study describing sociodemographic characteristics (age, sex assigned at birth, onset age, nationality, education, sex work, having a partner, having children, sexual orientation, religiousness, gender identification, and gender affirmation pathways). A snowball sample of 377 self-identified transgender adults living in Chile (Mage = 31.88, rangeage = 18-67) was collected for the purpose of this study. According to their sex assigned at birth, 139 participants were female and 238 male. Results revealed that sex assigned at birth was significantly associated with almost all the sociodemographic variables. Eight gender self-identification categories were obtained based on self-declaration. These gender identification categories varied according to sex assigned at birth. Finally, four patterns (clusters) of gender affirmative actions were identified among participants. These patterns indicated that the longer the gender affirmation pathway time, the greater the invasiveness level of the medical procedures used. Sex assigned at birth moderated the association between gender affirmation pathways and gender identity categories. Results were discussed highlighting the heterogeneity found in terms of sociodemographic characteristics, gender identification, and gender affirmation pathways.

Recomendaciones para la investigación psicológica con personas transgénero: Una aproximación desde una experiencia en Chile / Recommendations for psychological research with transgender people: an approach from an experience in Chile

Resumen El presente trabajo expone y fundamenta recomendaciones basadas en la experiencia de investigación en personas transgénero, con la intención de que puedan ser útiles a quienes realicen estudios con dicha población. Estas recomendaciones incluyen orientaciones conceptuales, metodológicas y éticas, aplicables a lo largo del proceso de investigación. En particular, las orientaciones cubren los siguientes temas: definir con precisión el colectivo con el que se trabaja, registrar la variedad de identificaciones de género posibles al interior del mismo, utilizar métodos de muestreo aptos para poblaciones de difícil acceso, retribuir la participación, incluir líderes e investigadores transgéneros como expertos, pilotar los instrumentos en la población que será investigada, optar por modalidades de recolección grupal de datos, ofrecer asistencia individualizada durante la recolección, utilizar un lenguaje no estigmatizante e inclusivo, convocar la participación en conjunto con organizaciones transgénero, atender a la movilidad geográfica de la población, realizar una escucha comprometida y contemplar protocolos de derivación, considerar las diferentes trayectorias de transición, realizar sesiones de interanálisis y, finalmente, difundir apropiadamente los hallazgos al interior de la población transgénero. Se discuten estas proposiciones en términos de sus efectos en las comunidades trans, su utilidad y alcances éticos, su articulación con exigencias generales de toda investigación y sus implicaciones para el activismo.

Abstract Prejudice and discrimination have important effects on the well-being and quality of life of trans people. Hence, investigating with said population implies, in addition to actions to obtain relevant and truthful information, having the necessary actions to attend to their needs and peculiarities. These are populations that are difficult to access (hard-to-reach), stigmatized, in which there is no defined sampling frame, that have physical and mental health indicators lower than those of any other group with which we have worked and that, therefore, it is necessary to take extreme the precautions not to reproduce types of relationships that may be harmful or offensive. The purpose of the present article was to systematize part of our field experience with transgender people, so that it can be useful for those who study with this population. These recommendations aim to provide some conceptual, methodological and ethical guidelines, useful throughout the research process. In particular, we made a series of recommendations that cover from the moment of taking conceptual decisions about the design of the study, through contact with the organizations, until the completion of the field work and subsequent stage of dissemination of results. In particular, a series of recommendations are made regarding: specifying the definition of the group with which one works, recording the variety of gender identifications as people present them, using to sampling methods for hard-to-reach populations or hidden populations, deliver a retribution for the participation (consider participants as experts to be compensated for their work), including activists as experts in every stage of the study (study design, field work, data analysis and dissemination of results), piloting the instruments in specific population, preferably opt for group applications modality and continue with a debriefing, have specific assistance for participants during the application (special needs derived from their age, educational level, reduced mobility, among others), use non-stigmatizing and inclusive language, call together with trans organizations (in order to establish greater trust in the population), attend to a mobility of the population (so as not to replicate the sample in different places), carry out a committed listening and contemplate referral protocols (if necessary given the type of situations described by the participants and their current degree of elaboration), consider different trajectories of transition, conduct inter-analysis sessions and disseminate appropriately within the transgender population. These propositions are discussed in terms of their effects on trans communities, their usefulness and ethical scope, their articulation with the general requirements of all research, and their implications for activism. On the other hand, these recommendations can serve as criteria for evaluating the ethical dimension of research projects with trans people. It may therefore be important to project reviewers, editors, and reviewers of manuscripts submitted for publication. The perspective that we assume in this work is aligned with those called "evidence-based activism", which implies articulating a variety of knowledge, scientifically accredited and of an "experiential" type, in order to explore situations in which the team members Research staff are part of networks that involve them personally in their study topics. It is precisely the relationship with groups that work for the rights of minorities, activists and members of these groups is essential, since they have knowledge acquired through their experience as part of discriminated groups and they can contribute to the mobilization of knowledge in the governance of health issues.
