Gestor de eventos de seguridad para monitoreo de los servidores windows de la empresa mazars Colombia S.A.S
La seguridad informática ha venido tomando importancia a nivel mundial, es por ello
por lo que las organizaciones empiezan a ver la necesidad de proteger los activos
de información de su entidad; en este sentido, para la ISO/IEC 27001 un activo de
información es: “algo que una organización valora y por lo tanto debe proteger”23
Para la elaboración de este proyecto de investigación se cuenta con el aval de
Mazars Colombia SAS, esta es una firma internacional que se especializa en
auditoria, contabilidad, consultoría, impuestos y servicios legales prestados a
diferentes tipos de empresas y clientes; este trabajo nace por la necesidad urgente
de la firma en monitorear sus servidores, ya que a través de su casa matriz está
impartiendo instrucciones donde se deben correlacionar los eventos de seguridad
de la información que reposa en los servidores de la compañía.
Es por lo anterior, que se planea implementar un gestor de eventos de seguridad en
la empresa Mazars Colombia SAS, a fin de realizar el monitoreo a los servidores
críticos, donde se envíen alertas al correo electrónico cuando se presenten eventos,
como accesos no autorizados, creación, modificación y eliminación de la
información que está alojada en los servidores.
Adicional a esto, se pretende realizar un análisis de la infraestructura de la empresa,
para que de este modo se puedan clasificar los eventos y a su vez se definan las
alertas. El presente proyecto estará dividido en tres fases con tareas como el
análisis de la información, implementación y pruebas de funcionalidad

Artículo científicoIn this work, we present a new metal organic framework Zn7(Ad)4(BTC)4(DMF)O·4DMA·3DMF·4H2O which was synthesized under hydrothermal conditions with adenine and trimesic acid (BTC) linkers. The structure was determined by single-crystal (XRD) and the compound was further characterized by Scanning electron microscopy (SEM), infrared spectroscopy (IR), and thermogravimetric analysis. The 3D anionic framework includes adenine present in two-different coordination modes, with dimethylammonium balancing the framework charg
XXV Curso Monográfico de Psiquiatría Infantil y la Adolescencia: Tópicos de Psicofarmacología Infantil - 2023
El XXV Curso Monográfico de Psiquiatría Infantil y de la Adolescencia, titulado "Tópicos de Psicofarmacología Infantil," fue un evento destacado en el campo de la salud mental infantil y adolescente. Durante tres días en septiembre de 2023, expertos líderes en la materia se reunieron para explorar a fondo la psicofarmacología en este grupo de edad.
El evento, dedicado a la memoria del Dr. Francisco Javier Valencia Granados, comenzó con una ceremonia de inauguración en la que participaron autoridades institucionales. Luego, se sucedieron conferencias magistrales que abordaron una amplia variedad de temas cruciales. Estos incluyeron aspectos fundamentales como la neurobioquímica farmacológica y una introducción a la psicofarmacología.
El programa se adentró en cuestiones específicas, como el uso de antipsicóticos en paidopsiquiatría, el abordaje de trastornos del aprendizaje, el tratamiento del suicidio desde una perspectiva psicofarmacológica, y la gestión farmacológica del insomnio en niños. Se exploraron temas especializados, como el tratamiento de la esquizofrenia en pacientes infantiles.
El segundo día se centró en trastornos emocionales en niños y adolescentes, destacando el tratamiento del trastorno depresivo, los trastornos ansiosos y el espectro autista. Se presentaron enfoques vanguardistas, como el uso de psicodélicos en adolescentes y las novedades en psicofarmacología, como el dextrometorfano y el bupropión. También se discutió el manejo de la epilepsia y la adicción a los videojuegos.
El tercer día se enfocó en el tratamiento farmacológico de trastornos pediátricos específicos, como el trastorno bipolar, el déficit de atención e hiperactividad, la enuresis y encopresis, parasomnias, y el abordaje neuropsiquiátrico en pacientes pediátricos con VIH. Se exploraron también trastornos de la conducta alimentaria y la disforia de género. El evento culminó con una reflexión sobre la salud mental en niños y un emotivo tributo al Dr. Francisco Javier
The Science Performance of JWST as Characterized in Commissioning
This paper characterizes the actual science performance of the James Webb
Space Telescope (JWST), as determined from the six month commissioning period.
We summarize the performance of the spacecraft, telescope, science instruments,
and ground system, with an emphasis on differences from pre-launch
expectations. Commissioning has made clear that JWST is fully capable of
achieving the discoveries for which it was built. Moreover, almost across the
board, the science performance of JWST is better than expected; in most cases,
JWST will go deeper faster than expected. The telescope and instrument suite
have demonstrated the sensitivity, stability, image quality, and spectral range
that are necessary to transform our understanding of the cosmos through
observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures;

Canagliflozin and Renal Outcomes in Type 2 Diabetes and Nephropathy
BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to 300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m 2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years

All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes.

Large expert-curated database for benchmarking document similarity detection in biomedical literature search
Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study
Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
