New Applications of Iodine(III) Reactivity: Synthesis and Functionalization of Heterocycles
S'han desenvolupat dues metodologies diferents per a la síntesi de indols emprant la reactivitat de iode hipervalente. En primer lloc, s'ha proposat una reacció de ciclació en la qual s'han obtingut un total de 21 exemples amb bons rendiments, a més d'estudiar el possible mecanisme d'aquesta reacció a través de diferents proves mecanístiques com ara la tècnica de marcatge de deuteri . D'altra banda, s'ha realitzat una metodologia alternativa amb substrats de partida diferents per obtenir un total de 18 exemples en bons rendiments a través tant d'una transformació estequiomètrica com catalítica. El mecanisme de la reacció s'ha estudiat en profunditat realitzant diferents estudis mecanístics, com per exemple, l'efecte dels substituents de diferent naturalesa electrònica en un dels anells aromàtics, a través de la correlació de Hammett.
A més de l'aplicació de compostos de iode hipervalente per a la síntesi d'heterocicles, els seus derivats quirals s'han fet servir per al desenvolupament d'una reacció enantioselectiva per a la 4-hidroxilació de fenols.Se han desarrollado dos metodologías diferentes para la síntesis de indoles empleando la reactividad de Yodo hipervalente. En primer lugar, se ha propuesto una reacción de ciclación en la que se han obtenido un total de 21 ejemplos con buenos rendimientos, además de estudiar el posible mecanismo de dicha reacción a través de diferentes pruebas mecanísticas como por ejemplo la técnica de marcaje de deuterio. Por otro lado, se ha realizado una metodología alternativa con sustratos de partida diferentes para obtener un total de 18 ejemplos en buenos rendimientos a través tanto de una transformación estequiométrica como catalítica. El mecanismo de la reacción se ha estudiado en profundidad realizando diferentes estudios mecanísticos, como por ejemplo, el efecto de los sustituyentes de diferente naturaleza electrónica en uno de los anillos aromáticos, a través de la correlación de Hammett.
Además de la aplicación de compuestos de yodo hipervalente para la síntesis de heterociclos, sus derivados quirales se han usado para el desarrollo de una reacción enantioselectiva para la 4-hidroxilación de fenoles.Two different methodologies have been developed for the synthesis of indoles using hypervalent iodine reactivity. First, a cyclization reaction has been proposed in which a total of 21 examples were obtained with good yields. In order to elucidate the reaction mechanism, different kinetic experimentes were performed such as the deuterium labellind technique . On the other hand, an alternative methodology has been performed with different starting materials obtaining a total of 18 examples in good yields through both a stoichiometric and catalytic transformation. The mechanism of the reaction has been studied by performing different mechanistic studies, such as the effect of the substituents of different electronic nature on one of the aromatic rings, through the Hammett correlation.
In addition to the application of hypervalent iodine compounds for the synthesis of heterocycles, their chiral derivatives have been used for the development of an enantioselective reaction for the 4-hydroxylation of phenols
Organic Law of Comprehensive Guarantee of Sexual Freedom: commentary on the penal reform
[ES] La aprobación de la Ley Orgánica 10/2022, de 6 de septiembre, de Garantía Integral de la Libertad Sexual, dada su naturaleza integral, ha implicado modificaciones importantes de varios textos normativos, entre ellos, las que afectan al DP (y, conectado con este, el Derecho penitenciario, en algún aspecto puntual). Este trabajo estudia las principales modificaciones producidas en este sector del ordenamiento jurídico, con un análisis previo del concepto y finalidad de la LOGILS, haciendo un análisis del concepto, violencia sexual, que es el que aglutina las conductas que afectan, de manera más o menos directa, al objeto de protección, la libertad sexual. También se hará una breve referencia a las principales razones esgrimidas para la reforma de los delitos que, de manera más directa, protegen este bien jurídico: los delitos contra la libertad sexual, y, más concretamente, los delitos de agresiones sexuales. Finalmente, se hará un recorrido de los cambios que introduce esta LO en el CP, desde la nueva regulación del periodo de seguridad (que conecta con el Derecho penitenciario) hasta la protección penal de la libertad sexual (y otros bienes jurídicos) frente a novedosas conductas relacionadas con la ciberdelincuencia.[EN] The approval of Organic Law 10/2022, of September 6, on the Comprehensive Guarantee of Sexual Freedom, given its comprehensive nature, has implied important modifications to several regulatory texts, among them, those that affect the DP (and, connected with this, penitentiary law, in some specific aspect). This work studies the main modifications produced in this sector of the legal system, with a prior analysis of the concept and purpose of the LOGILS, making an analysis of the concept, sexual violence, which is what brings together the behaviors that affect, in a more or less directly, to the object of protection, sexual freedom. A brief reference will also be made to the main reasons given for the reform of the crimes that, in a more direct way, protect this legal right: crimes against sexual freedom, and, more specifically, crimes of sexual assault. Finally, a review will be made of the changes that this LO introduces in the CP, from the new regulation of the security period (which connects with penitentiary law) to the criminal protection of sexual freedom (and other legal rights) against new behaviors related to cybercrime

NeuroBench:A Framework for Benchmarking Neuromorphic Computing Algorithms and Systems
Neuromorphic computing shows promise for advancing computing efficiency and capabilities of AI applications using brain-inspired principles. However, the neuromorphic research field currently lacks standardized benchmarks, making it difficult to accurately measure technological advancements, compare performance with conventional methods, and identify promising future research directions. Prior neuromorphic computing benchmark efforts have not seen widespread adoption due to a lack of inclusive, actionable, and iterative benchmark design and guidelines. To address these shortcomings, we present NeuroBench: a benchmark framework for neuromorphic computing algorithms and systems. NeuroBench is a collaboratively-designed effort from an open community of nearly 100 co-authors across over 50 institutions in industry and academia, aiming to provide a representative structure for standardizing the evaluation of neuromorphic approaches. The NeuroBench framework introduces a common set of tools and systematic methodology for inclusive benchmark measurement, delivering an objective reference framework for quantifying neuromorphic approaches in both hardware-independent (algorithm track) and hardware-dependent (system track) settings. In this article, we present initial performance baselines across various model architectures on the algorithm track and outline the system track benchmark tasks and guidelines. NeuroBench is intended to continually expand its benchmarks and features to foster and track the progress made by the research community
Beta-Blocker Use in Older Hospitalized Patients Affected by Heart Failure and Chronic Obstructive Pulmonary Disease: An Italian Survey From the REPOSI Register
Beta (β)-blockers (BB) are useful in reducing morbidity and mortality in patients with heart failure (HF) and concomitant chronic obstructive pulmonary disease (COPD). Nevertheless, the use of BBs could induce bronchoconstriction due to β2-blockade. For this reason, both the ESC and GOLD guidelines strongly suggest the use of selective β1-BB in patients with HF and COPD. However, low adherence to guidelines was observed in multiple clinical settings. The aim of the study was to investigate the BBs use in older patients affected by HF and COPD, recorded in the REPOSI register. Of 942 patients affected by HF, 47.1% were treated with BBs. The use of BBs was significantly lower in patients with HF and COPD than in patients affected by HF alone, both at admission and at discharge (admission, 36.9% vs. 51.3%; discharge, 38.0% vs. 51.7%). In addition, no further BB users were found at discharge. The probability to being treated with a BB was significantly lower in patients with HF also affected by COPD (adj. OR, 95% CI: 0.50, 0.37-0.67), while the diagnosis of COPD was not associated with the choice of selective β1-BB (adj. OR, 95% CI: 1.33, 0.76-2.34). Despite clear recommendations by clinical guidelines, a significant underuse of BBs was also observed after hospital discharge. In COPD affected patients, physicians unreasonably reject BBs use, rather than choosing a β1-BB. The expected improvement of the BB prescriptions after hospitalization was not observed. A multidisciplinary approach among hospital physicians, general practitioners, and pharmacologists should be carried out for better drug management and adherence to guideline recommendations
Antidiabetic Drug Prescription Pattern in Hospitalized Older Patients with Diabetes
Objective: To describe the prescription pattern of antidiabetic and cardiovascular drugs in a cohort of hospitalized older patients with diabetes. Methods: Patients with diabetes aged 65 years or older hospitalized in internal medicine and/or geriatric wards throughout Italy and enrolled in the REPOSI (REgistro POliterapuie SIMI—Società Italiana di Medicina Interna) registry from 2010 to 2019 and discharged alive were included. Results: Among 1703 patients with diabetes, 1433 (84.2%) were on treatment with at least one antidiabetic drug at hospital admission, mainly prescribed as monotherapy with insulin (28.3%) or metformin (19.2%). The proportion of treated patients decreased at discharge (N = 1309, 76.9%), with a significant reduction over time. Among those prescribed, the proportion of those with insulin alone increased over time (p = 0.0066), while the proportion of those prescribed sulfonylureas decreased (p < 0.0001). Among patients receiving antidiabetic therapy at discharge, 1063 (81.2%) were also prescribed cardiovascular drugs, mainly with an antihypertensive drug alone or in combination (N = 777, 73.1%). Conclusion: The management of older patients with diabetes in a hospital setting is often sub-optimal, as shown by the increasing trend in insulin at discharge, even if an overall improvement has been highlighted by the prevalent decrease in sulfonylureas prescription
The “Diabetes Comorbidome”: A Different Way for Health Professionals to Approach the Comorbidity Burden of Diabetes
(1) Background: The disease burden related to diabetes is increasing greatly, particularly in older subjects. A more comprehensive approach towards the assessment and management of diabetes’ comorbidities is necessary. The aim of this study was to implement our previous data identifying and representing the prevalence of the comorbidities, their association with mortality, and the strength of their relationship in hospitalized elderly patients with diabetes, developing, at the same time, a new graphic representation model of the comorbidome called “Diabetes Comorbidome”. (2) Methods: Data were collected from the RePoSi register. Comorbidities, socio-demographic data, severity and comorbidity indexes (Cumulative Illness rating Scale CIRS-SI and CIRS-CI), and functional status (Barthel Index), were recorded. Mortality rates were assessed in hospital and 3 and 12 months after discharge. (3) Results: Of the 4714 hospitalized elderly patients, 1378 had diabetes. The comorbidities distribution showed that arterial hypertension (57.1%), ischemic heart disease (31.4%), chronic renal failure (28.8%), atrial fibrillation (25.6%), and COPD (22.7%), were the more frequent in subjects with diabetes. The graphic comorbidome showed that the strongest predictors of death at in hospital and at the 3-month follow-up were dementia and cancer. At the 1-year follow-up, cancer was the first comorbidity independently associated with mortality. (4) Conclusions: The “Diabetes Comorbidome” represents the perfect instrument for determining the prevalence of comorbidities and the strength of their relationship with risk of death, as well as the need for an effective treatment for improving clinical outcomes
