Meeting of epilepsy experts

Se estima que aproximadamente setenta millones de personas viven con epilepsia, de las cuales 80 % viven en países de ingreso bajo o medio como Colombia. Las personas con epilepsia viven con necesidades insatisfechas. Esta enfermedad, a pesar de ser prevalente, no se ve reflejada en las prioridades de los servicios de salud. Por lo anterior, existen importantes retos en el tratamiento integral de esta enfermedad. La epilepsia, enfermedad estigmatizada, más allá de los gastos farmacológicos tiene un impacto psicológico y social que resulta en un espectro de discapacidad muy variado, el cual cursa con dolencias notables como la depresión y la ansiedad. Asimismo, las personas con epilepsia tienen una menor tasa de empleo que las personas sin epilepsia, incluso ocho años después de haber comenzado la terapia farmacológica. El estado libre de crisis, uno de los objetivos principales en la terapia de epilepsia, es difícil de alcanzar en algunos pacientes y, si bien la cantidad de medicamentos anticonvulsivantes ha aumentado notablemente desde 1990, las crisis pueden ser generadas a partir de múltiples mecanismos, lo que se traduce en un reto a la hora de buscar blancos terapéuticos para los medicamentos ya que varias etiologías se pueden traducir clínicamente en tipos de crisis similares. Aunque la monoterapia sea el ideal del tratamiento en epilepsia, la prioridad es alcanzar una reducción en la frecuencia ictal o un estado libre de crisis, por lo que si no se alcanza con el primer medicamento, la opción de añadir un segundo medicamento es aceptada plenamente. Existe una gran preocupación alrededor del uso de los medicamentos genéricos, los copia o multifuente y los originales, ya que la concentración y la absorción son muy importantes para su eficacia y seguridad, y es conocido que no deben variar más del 5-10 % para evitar cambios del patrón ictal de los pacientes. Se ha considerado que el cambio a medicamentos genéricos o multifuente está asociado con cambios en perfil de seguridad y en el patrón ictal, además de un aumento del uso de los servicios de salud y una alta tasa de cambio a medicamentos de marca, lo que podría aumentar los costos en salud. Por todo lo anterior, se considera que una atención óptima a los pacientes con epilepsia hace referencia a un manejo interdisciplinario en el cual se garantice el acceso y el seguimiento, para lo cual se deben aceptar retos como el entrenamiento del personal en atención primaria y la continuidad del manejo para evitar cambios en la biodisponibilidad, el perfil de seguridad y la toxicidad de los medicamentos.Artículo original89-98It is estimated that approximately 70 million people live in the world with epilepsy, of which 80 °% live in low-or middle-income countries such as Colombia. Despite this, people with epilepsy live with unmet needs as, eventhough epilepsy is a prevalent disease, it is not reflected in the priorities of health services. This is why there are important challenges in the comprehensive treatment of epilepsy. Epilepsy is a stigmatized disease that, beyond pharmacological expenses, has a psychological and social impact that results in a very varied spectrum of disability, suffering from notable depressions such as depression and anxiety. Likewise, people with epilepsy have a lower employment rate than people without epilepsy even up to 8 years after starting pharmacological therapy. The crisis-free state, which is one of the main objectives in the therapy of epilepsy, is difficult to achieve in some patients and although the amount of anticonvulsant drugs has increased markedly since 1990, the crises can be generated from multiple mechanisms, which translates into a challenge when looking for therapeutic targets for medications since several etiologies can be translated clinically into similar types of crisis. Although monotherapy is the ideal treatment in epilepsy, the priority is to achieve a reduction in ictal frequency or a crisis-free state, so if it is not achieved with the first medication, the option of adding a second medication is fully accepted. . There is a great concern about the use of generic drugs, copy or multi-source and originals since the concentration and absorption is very important for their effectiveness and safety and it is known that they should not vary more than 5-10 % to avoid Changes in the ictal pattern of patients. It has been considered that the change to generic or multi-source drugs is associated with changes in the safety profile and changes in the ictal pattern, in addition to an increase in the use of health services and a high rate of change to brand-name drugs, which could increase health costs. For all of the above, it is considered that optimal care for patients with epilepsy refers to an interdisciplinary management in which access and follow-up are guaranteed, for which challenges such as training of personnel in primary care and health care should be accepted. continuity of management to avoid changes in bioavaila-bility, safety profile and drug toxicity

ToSHI - Towards Secure Heterogeneous Integration: Security Risks, Threat Assessment, and Assurance

The semiconductor industry is entering a new age in which device scaling and cost reduction will no longer follow the decades-long pattern. Packing more transistors on a monolithic IC at each node becomes more difficult and expensive. Companies in the semiconductor industry are increasingly seeking technological solutions to close the gap and enhance cost-performance while providing more functionality through integration. Putting all of the operations on a single chip (known as a system on a chip, or SoC) presents several issues, including increased prices and greater design complexity. Heterogeneous integration (HI), which uses advanced packaging technology to merge components that might be designed and manufactured independently using the best process technology, is an attractive alternative. However, although the industry is motivated to move towards HI, many design and security challenges must be addressed. This paper presents a three-tier security approach for secure heterogeneous integration by investigating supply chain security risks, threats, and vulnerabilities at the chiplet, interposer, and system-in-package levels. Furthermore, various possible trust validation methods and attack mitigation were proposed for every level of heterogeneous integration. Finally, we shared our vision as a roadmap toward developing security solutions for a secure heterogeneous integration

A large scale hearing loss screen reveals an extensive unexplored genetic landscape for auditory dysfunction

The developmental and physiological complexity of the auditory system is likely reflected in the underlying set of genes involved in auditory function. In humans, over 150 non-syndromic loci have been identified, and there are more than 400 human genetic syndromes with a hearing loss component. Over 100 non-syndromic hearing loss genes have been identified in mouse and human, but we remain ignorant of the full extent of the genetic landscape involved in auditory dysfunction. As part of the International Mouse Phenotyping Consortium, we undertook a hearing loss screen in a cohort of 3006 mouse knockout strains. In total, we identify 67 candidate hearing loss genes. We detect known hearing loss genes, but the vast majority, 52, of the candidate genes were novel. Our analysis reveals a large and unexplored genetic landscape involved with auditory function

Mutation in SUMO E3 ligase, SIZ1, Disrupts the Mature Female Gametophyte in Arabidopsis

Female gametophyte is the multicellular haploid structure that can produce embryo and endosperm after fertilization, which has become an attractive model system for investigating molecular mechanisms in nuclei migration, cell specification, cell-to-cell communication and many other processes. Previous reports found that the small ubiquitin-like modifier (SUMO) E3 ligase, SIZ1, participated in many processes depending on particular target substrates and suppression of salicylic acid (SA) accumulation. Here, we report that SIZ1 mediates the reproductive process. SIZ1 showed enhanced expression in female organs, but was not detected in the anther or pollen. A defect in the siz1-2 maternal source resulted in reduced seed-set regardless of high SA concentration within the plant. Moreover, aniline blue staining and scanning electron microscopy revealed that funicular and micropylar pollen tube guidance was arrested in siz1-2 plants. Some of the embryo sacs of ovules in siz1-2 were also disrupted quickly after stage FG7. There was no significant affects of the siz1-2 mutation on expression of genes involved in female gametophyte development- or pollen tube guidance in ovaries. Together, our results suggest that SIZ1 sustains the stability and normal function of the mature female gametophyte which is necessary for pollen tube guidance

How many bird and mammal extinctions has recent conservation action prevented?

Aichi Target 12 of the Convention on Biological Diversity (CBD) aims to ‘prevent extinctions of known threatened species’. To measure its success, we used a Delphi expert elicitation method to estimate the number of bird and mammal species whose extinctions were prevented by conservation action in 1993 - 2020 (the lifetime of the CBD) and 2010 - 2020 (the timing of Aichi Target 12). We found that conservation prevented 21–32 bird and 7–16 mammal extinctions since 1993, and 9–18 bird and 2–7 mammal extinctions since 2010. Many remain highly threatened, and may still become extinct in the near future. Nonetheless, given that ten bird and five mammal species did go extinct (or are strongly suspected to) since 1993, extinction rates would have been 2.9–4.2 times greater without conservation action. While policy commitments have fostered significant conservation achievements, future biodiversity action needs to be scaled up to avert additional extinctions

How many bird and mammal extinctions has recent conservation action prevented?

Aichi Target 12 of the Convention on Biological Diversity (CBD) contains the aim to ‘prevent extinctions of known threatened species’. To measure the degree to which this was achieved, we used expert elicitation to estimate the number of bird and mammal species whose extinctions were prevented by conservation action in 1993–2020 (the lifetime of the CBD) and 2010–2020 (the timing of Aichi Target 12). We found that conservation action prevented 21–32 bird and 7–16 mammal extinctions since 1993, and 9–18 bird and two to seven mammal extinctions since 2010. Many remain highly threatened and may still become extinct. Considering that 10 bird and five mammal species did go extinct (or are strongly suspected to) since 1993, extinction rates would have been 2.9–4.2 times greater without conservation action. While policy commitments have fostered significant conservation achievements, future biodiversity action needs to be scaled up to avert additional extinctions.https://wileyonlinelibrary.com/journal/conlMammal Research Institut

Pulsed quantum cascade laser-based CRDS substance detection: real-time detection of TNT

This paper presents experimental results from a pulsed quantum cascade laser based cavity ringdown spectrometer used as a high-throughput detection system. The results were obtained from an optical cavity with 99.8% input and output coupling mirrors that was rapidly swept (0.2s to 7s sweep times) between 1582.25 cm−1 (6.3201μm) and 1697.00 cm−1 (5.8928μm). The spectrometer was able to monitor gas species over the pressure range 585 torr to 1μtorr, and the analysis involves a new digital data processing system that optimises the processing speed and minimises the data storage requirements. In this approach we show that is it not necessary to make direct measurements of the ringdown time of the cavity to obtain the system dynamics. Furthermore, we show that correct data processing is crucial for the ultimate implementation of a wideband IR spectrometer that covers a range similar to that of commercial Fourier transform infrared instruments
