Linear Program for Testing Nonclassicality and an Open-Source Implementation.

A well-motivated method for demonstrating that an experiment resists any classical explanation is to show that its statistics violate generalized noncontextuality. We here formulate this problem as a linear program and provide an open-source implementation of it which tests whether or not any given prepare-measure experiment is classically explainable in this sense. The input to the program is simply an arbitrary set of quantum states and an arbitrary set of quantum effects; the program then determines if the Born rule statistics generated by all pairs of these can be explained by a classical (noncontextual) model. If a classical model exists, it provides an explicit model. If it does not, then it computes the minimal amount of noise that must be added such that a model does exist, and then provides this model. We generalize all these results to arbitrary generalized probabilistic theories (and accessible fragments thereof) as well; indeed, our linear program is a test of simplex embeddability as introduced in Schmid et al. [PRX Quantum 2, 010331 (2021).2691-339910.1103/PRXQuantum.2.010331] and generalized in Selby et al. [Phys. Rev. A 107, 062203 (2023).PLRAAN2469-992610.1103/PhysRevA.107.062203].

Assessing Formability and Failure of UHMWPE Sheets through SPIF: A Case Study in Medical Applications.

This work presents a comprehensive investigation of an experimental study conducted on ultra-high molecular weight polyethylene (UHMWPE) sheets using single point incremental forming (SPIF). The analysis is performed within a previously established research framework to evaluate formability and failure characteristics, including necking and fracture, in both conventional Nakajima tests and incremental sheet forming specimens. The experimental design of the SPIF tests incorporates process parameters such as spindle speed and step down to assess their impact on the formability of the material and the corresponding failure modes. The results indicate that a higher step down value has a positive effect on formability in the SPIF context. The study has identified the tool trajectory in SPIF as the primary influencing factor in the twisting failure mode. Implementing a bidirectional tool trajectory effectively reduced instances of twisting. Additionally, this work explores a medical case study that examines the manufacturing of a polyethylene liner device for a total hip replacement. This investigation critically analyses the manufacturing of plastic liner using SPIF, focusing on its formability and the elastic recovery exhibited by the material.

Contextuality without Incompatibility.

The existence of incompatible measurements is often believed to be a feature of quantum theory which signals its inconsistency with any classical worldview. To prove the failure of classicality in the sense of Kochen-Specker noncontextuality, one does indeed require sets of incompatible measurements. However, a more broadly applicable notion of classicality is the existence of a generalized-noncontextual ontological model. In particular, this notion can imply constraints on the representation of outcomes even within a single nonprojective measurement. We leverage this fact to demonstrate that measurement incompatibility is neither necessary nor sufficient for proofs of the failure of generalized noncontextuality. Furthermore, we show that every proof of the failure of generalized noncontextuality in a quantum prepare-measure scenario can be converted into a proof of the failure of generalized noncontextuality in a corresponding scenario with no incompatible measurements.

Experience With the Use of Baricitinib and Tocilizumab Monotherapy or Combined, in Patients With Interstitial Pneumonia Secondary to Coronavirus COVID19: A Real-World Study.

OBJECTIVE: To describe the experience of treatment with baricitinib (BARI) and/or tocilizumab (TCZ), in monotherapy or combined, in patients admitted for interstitial pneumonia secondary to COVID19, and for 30 days after discharge. METHODS: Medical records of patients admitted with COVID19 and IP with PaO2/FiO2<300, treated with BARI and/or TCZ, and compared with patients who did not, were retrospectively reviewed. RESULTS: Sixty patients were included; 43 (72%) are males, mean age 67 (SD: 14) years (<50 years: 17%; 51-70: 30%; >70: 53%), with 8.5 (SD: 1) days of symptoms. Sixteen (27%) patients required ICU (94% in <70 years). Fifteen (25%) patients died, 67% in >70 years; 11 (18%) patients died in the first 15 days of admission and 4 (7%) between days 16 to 30. Twenty-three (38%) patients received BARI, 12 (52%) monotherapy (Group 1), during 6 (SD: 2.6) days on average, none required ICU and 2 (17%) died. Thirty-one (52%) patients received TCZ, 20 (33%) as monotherapy (Group 2), 16 (52%) patients required ICU and 4 (20%) died. In the 11 (18%) patients who received BARI (2.8 [SD: 2.5] days average) and TCZ combined (Group 3), 3 (27%) required ICU and died. There were no severe side effects in BARI or TCZ patients. In the 17 (28%) patients who received neither BARI nor TCZ (Group 4), none required ICU and 6 (35%) died. Mean (SD) PaO2/FiO2 at admission between groups was respectively: 167 (82.3), 221 (114.9), 236 (82.3), 276 (83.2). CONCLUSION: Treatment with BARI and TCZ did not cause serious side effects. They could be considered early in patients with NI secondary to COVID19 and impaired PaO2/PaFi.

A propósito de un caso: presentación atípica de rotura uterina / A case report: unusual presentation of uterine rupture

RESUMEN La rotura del útero gestante se define como una solución de continuidad patológica de la pared uterina, situada con mayor frecuencia en el segmento inferior. La rotura de un útero intacto es muy rara, su incidencia está estimada entre 1/5700 y 1/20000 embarazos. Su prevalencia ha aumentado dado el incremento de parto vaginal con cesárea anterior. Actualmente oscila entre el 0.3 y el 1 %, siendo mayor en mujeres en las que tiene lugar un intento de parto vaginal tras cesárea (0,78%) que en aquellas en las que se lleva a cabo una cesárea electiva (0,22%). En cuanto a su diagnóstico, suele ser precoz, dada la clínica de gravedad con la que debutan. En este caso se presenta una evolución atípica de rotura uterina, donde la paciente se mantiene asintomática hasta que acude a urgencias cinco días después del parto con fiebre y dolor abdominal; gracias a la ecografía abdominal y trans-vaginal se pudo establecer rápidamente el diagnóstico y así proceder a su inmediata reparación quirúrgica.

ABSTRACT Rupture of the pregnant uterus is defined as a solution of pathological continuity of the uterine wall, most often located in the lower segment. The rupture of an intact uterus is very rare, its incidence is estimated between 1/5700 and 1/20000 pregnancies. Its prevalence has increased given the increase in vaginal delivery with previous caesarean section. Currently, it ranges between 0.3 and 1%, being higher in women with a vaginal delivery after caesarean section (0.78%) than in those who undergo an elective caesarean section (0.22%). Their diagnosis is usually early given by the severity of the debut. In this case, there is an atypical evolution of uterine rupture where the patient remains asymptomatic until she goes to the emergency room five days after delivery with fever and abdominal pain; Because of the abdominal and transvaginal ultrasound, the diagnosis could be quickly established and thus proceed to immediate surgical repair.

Reference Frames Which Separately Store Noncommuting Conserved Quantities.

Even in the presence of conservation laws, one can perform arbitrary transformations on a system if given access to a suitable reference frame, since conserved quantities may be exchanged between the system and the frame. Here we explore whether these quantities can be separated into different parts of the reference frame, with each part acting as a "battery" for a distinct quantity. For systems composed of spin-1/2 particles, we show that the components of angular momentum S_{x}, S_{y}, and S_{z} (noncommuting conserved quantities) may be separated in this way, and also provide several extensions of this result. These results also play a key role in the quantum thermodynamics of noncommuting conserved quantities.

Bipartite Postquantum Steering in Generalized Scenarios.

The study of stronger-than-quantum effects is a fruitful line of research that provides valuable insight into quantum theory. Unfortunately, traditional bipartite steering scenarios can always be explained by quantum theory. Here, we show that, by relaxing this traditional setup, bipartite steering incompatible with quantum theory is possible. The two scenarios we describe, which still feature Alice remotely steering Bob's system, are (i) one where Bob also has an input and operates on his subsystem, and (ii) the "instrumental steering" scenario. We show that such bipartite postquantum steering is a genuinely new type of postquantum nonlocality, which does not follow from postquantum Bell nonlocality. In addition, we present a method to bound quantum violations of steering inequalities in these scenarios.

Asymptomatic Strongyloidiasis among Latin American Migrants in Spain: A Community-Based Approach.

Strongyloides stercoralis infection is frequently underdiagnosed since many infections remain asymptomatic. AIM: To estimate the prevalence and characteristics of asymptomatic S. stercoralis infection in Latin American migrants attending a community-based screening program for Chagas disease in Spain. METHODOLOGY: Three community-based Chagas disease screening campaigns were performed in Alicante (Spain) in 2016, 2017, and 2018. Serological testing for S. stercoralis infection was performed using a non-automatized IVD-ELISA detecting IgG (DRG Instruments GmbH, Marburg, Germany). RESULTS: Of the 616 migrants from Central and South America who were screened, 601 were included in the study: 100 children and adolescents (<18 years of age) and 501 adults. Among the younger group, 6 participants tested positive (prevalence 6%, 95% confidence interval [CI] 2.5% to 13.1%), while 60 adults did so (prevalence 12%, 95% CI 9.3% to 15.3%). S. stercoralis infection was more common in men than in women (odds ratio adjusted [ORa] 2.28, 95% CI 1.289 to 4.03) and in those from Bolivia (ORa 2.03, 95% CI 1.15 to 3.59). Prevalence increased with age (ORa 1.02, 95% CI 0.99 to 1.05). In contrast, a university education had a protective effect (ORa 0.29, 95% CI 0.31 to 0.88). Forty-one (41/66; 62.1%) of the total cases of S. stercoralis infection were treated at the health care center. Positive stool samples were observed in 19.5% of the followed-up positive cases. CONCLUSION: Incorporating serological screening for S. stercoralis into community-based screening for Chagas disease is a useful intervention to detect asymptomatic S. stercoralis infection in Central and South American migrants and an opportunity to tackle neglected tropical diseases in a transversal way. The remaining challenge is to achieve patients' adherence to the medical follow-up.

On the Determination of Forming Limits in Polycarbonate Sheets.

By proposing an adaptation of the methodology usually used in metal forming, this paper aims to provide a general procedure for determining the forming limits, by necking and fracture, of polymeric sheet. The experimental work was performed by means of Nakajima specimens with different geometries to allow to obtain strains in the tensile, plane, biaxial and equibiaxial states for Polycarbonate sheet with 1 mm of thickness. The application of the time-dependent and flat-valley approaches used in metals has been revealed appropriate to characterize the onset of necking and obtain the forming limits of polycarbonate, despite the stable necking propagation typical of polymeric sheets. An analysis of the evolution of the strain paths along a section perpendicular to the crack allowed for a deeper understanding of the steady necking propagation behaviour and the adoption of the methodology of metals to polymers. The determination of the fracture strains was enhanced with the consideration of the principal strains of the DIC system in the last stage, just before fracture, due to the significant elastic recovery typical of polymeric sheets. As a result of this analysis, accurate formability limits by necking and fracture are obtained for polycarbonate sheet, together with the principal strain space, providing a general framework for analysing incremental sheet forming processes where the knowledge of the fracture limits is relevant.

Almost-Quantum Correlations Violate the No-Restriction Hypothesis.

To identify which principles characterize quantum correlations, it is essential to understand in which sense this set of correlations differs from that of almost-quantum correlations. We solve this problem by invoking the so-called no-restriction hypothesis, an explicit and natural axiom in many reconstructions of quantum theory stating that the set of possible measurements is the dual of the set of states. We prove that, contrary to quantum correlations, no generalized probabilistic theory satisfying the no-restriction hypothesis is able to reproduce the set of almost-quantum correlations. Therefore, any theory whose correlations are exactly, or very close to, the almost-quantum correlations necessarily requires a rule limiting the possible measurements. Our results suggest that the no-restriction hypothesis may play a fundamental role in singling out the set of quantum correlations among other nonsignaling ones.

Quantum reference frames and their applications to thermodynamics.

We construct a quantum reference frame, which can be used to approximately implement arbitrary unitary transformations on a system in the presence of any number of extensive conserved quantities, by absorbing any back action provided by the conservation laws. Thus, the reference frame at the same time acts as a battery for the conserved quantities. Our construction features a physically intuitive, clear and implementation-friendly realization. Indeed, the reference system is composed of the same types of subsystems as the original system and is finite for any desired accuracy. In addition, the interaction with the reference frame can be broken down into two-body terms coupling the system to one of the reference frame subsystems at a time. We apply this construction to quantum thermodynamic set-ups with multiple, possibly non-commuting conserved quantities, which allows for the definition of explicit batteries in such cases.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'.

Objetivo: El objetivo de este trabajo es describir las características de los pacientes con fractura de cadera en los hospitales públicos de Castilla y León recogidos durante un periodo de tiempo de 3 meses (noviembre del 2014 y octubre y noviembre del 2015). Material y método: El grupo de trabajo de Ortogeriatría de Castilla y León elabora un registro común para recoger datos de las fracturas de cadera. Se incluyen mayores de 74 años ingresados por fractura de cadera, en 13 hospitales públicos de la comunidad, los meses de noviembre del 2014 y octubre-noviembre del 2015. Es un estudio multicéntrico, prospectivo y observacional en el que se recogieron variables clínicas, funcionales, sociales y mortalidad intrahospitalaria. Resultados: Se analizaron 776 pacientes, con una edad media de 86,6±6 años. La demora quirúrgica fue de 4±2,8 días y la estancia media hospitalaria de 10±4,7 días. El riesgo anestésico fue ASA 3±0,6. El 66,5% de los pacientes tuvieron complicaciones médicas intrahospitalarias y precisaron transfusión el 55,5%. Fallecieron durante la hospitalización un 4,6%. La estancia media prequirúrgica se relacionó con la estancia global, con p<0,001. Conclusiones: Los registros de fractura de cadera son una herramienta esencial para evaluar el proceso y mejorar la calidad asistencial de estos pacientes. Este es el primer registro multicéntrico de fracturas de cadera en ancianos realizado en una región de España y puede ser un buen precedente de referencia ante el futuro registro nacional (AU)

Objective: The objective of this study is to describe the characteristics of the patients with hip fracture admitted to the Public Hospitals of Castilla y León during three monthly periods (November 2014, and October and November 2015). Material and method: The Castilla y León orthogeriatrics work group created a common register to collect data on hip fractures. The study included patients 75 years-old and over hospitalised with hip fractures in the 13 public hospitals in the community during November 2014, and October and November 2015. A multicentre, prospective, and observational study was conducted, in which clinical, functional, and social variables, as well as in-hospital mortality, were collected. Results: The analysis included data from a total of 776 patients with a mean age of 86 (±6) years. The surgical delay was 4±2.8 days, and the mean hospital stay was 10±4.7 days. The anaesthesia risk was ASA 3±0.6. Around two-thirds (66.5%) of the patients had medical complications while in hospital, and 55.5% required a transfusion. In-hospital mortality was 4.6%. The mean pre-surgical stay was related to the overall stay: P<.001. Conclusions: Hip fracture registers are an essential tool for evaluating the process and for improving the treatment quality of these patients. This is the first multicentre register of hip fracture in the elderly created in a Spanish region, and could be a good precedent reference for a future national register (AU)

Postquantum Steering.

The discovery of postquantum nonlocality, i.e., the existence of nonlocal correlations that are stronger than any quantum correlations but nevertheless consistent with the no-signaling principle, has deepened our understanding of the foundations of quantum theory. In this work, we investigate whether the phenomenon of Einstein-Podolsky-Rosen steering, a different form of quantum nonlocality, can also be generalized beyond quantum theory. While post-quantum steering does not exist in the bipartite case, we prove its existence in the case of three observers. Importantly, we show that postquantum steering is a genuinely new phenomenon, fundamentally different from postquantum nonlocality. Our results provide new insight into the nonlocal correlations of multipartite quantum systems.

Actividad ortogeriátrica en los hospitales públicos de Castilla y León: descripción y revisión de la literatura / Orthogeriatric activity in public hospitals of Castilla y León: Description and review of the literature

El beneficio de la colaboración entre traumatología y geriatría en la atención del anciano que ingresa por fractura de cadera está ampliamente demostrado. Para conocer las características de colaboración entre Traumatología y Geriatría en los hospitales públicos de Castilla y León se realizó una encuesta a todos los geriatras de la comunidad, interrogándoles sobre el tipo de colaboración que mantenían con Traumatología para la atención del anciano que ingresa con fractura de cadera y detalles sobre el tratamiento de las complicaciones. Los resultados más relevantes fueron que la mayoría de los hospitales mantienen una colaboración ortogeriátrica con alto grado de implicación por parte de Geriatría y el geriatra atiende las complicaciones médicas de estos pacientes.

Utilización de la opinión de los pacientes para la mejora: 5 años de seguimiento (2001-2005) / Using patients’ opinions for quality improvement: a 5-year follow-up (2001-2005)

Objetivo: Evaluar, desde la perspectiva de los pacientes, la evolución de la calidad en los últimos 5 años con el fin de acercarnos a sus expectativas en el nuevo hospital. Método: El procedimiento utiliza como referencia los resultados de un estudio de opinión realizado en el hospital, en el año 2001, para contrastar con los resultados de las encuestas anuales y complementar con información procedente de reclamaciones escritas y demandas de responsabilidad patrimonial. Resultados: Se han recibido y procesado, en el período considerado, 821 encuestas (tasa de respuesta del 22,3%), 3.756 reclamaciones y 105 demandas de responsabilidad administrativa. Las encuestas han mostrado un grado de satisfacción del 96% y el estudio de evolución ha detectado diferencias significativas en confortabilidad y capacidad de respuesta. Los motivos de reclamación más frecuentes han sido: transporte sanitario (15,3%), demora en la asistencia (12,6%) y lista de espera (9,3%). Las demandas, estimadas positivamente sólo el 20%, destacan como motivo final principal la muerte o el resultado secundario grave (59%), y como causas primordiales, la omisión de acción (42,9%) y la práctica no adecuada (22,9%). Discusión: Se ha detectado un ligero empeoramiento de la opinión del paciente en los últimos 5 años, que se relaciona con un incremento de las expectativas del paciente. Los motivos de reclamaciones y demandas son independientes de los problemas destacados en el aspecto de opinión y evidencian dimensiones distintas pero coinciden en ciertos aspectos. Queda pendiente una nota de atención en el área de urgencias y, por supuesto, los problemas relacionados con el confort, cuya mejoría es fácil y evidente con la inauguración del nuevo hospital

Objective: To evaluate changes in quality over a 5-year period from the perspective of patients, in an attempt to meet their expectations in a new hospital. Method: The procedure takes as a reference the results of an opinion survey carried out in the hospital in 2001 and compares these results with those of annual surveys and completes them with information from written complaints and demands for accountability. Results: During the period studied, 821 surveys (a response rate of 22.3%), 3,756 complaints and 105 demands for administrative accountability were received and processed. The surveys revealed a degree of satisfaction of 96%, and study of the changes detected significant differences in comfort and response capacity. The most common reasons for complaints were medical transport (15.3%), delays in receiving care (12.6%), and waiting lists (9.3%). The main reasons for demands for accountability (only 20% of which were accepted) were death or serious secondary outcomes (59%), and the principal causes were related to omissions (42.9%) or malpractice (22.9%). Discussion: Patients' opinions tended to worsen slightly over the 5-year period studied, related to their increased expectations. Although the reasons for making complaints and demands were independent of the problems identified in patients' opinions and showed different dimensions, there were certain areas of overlap. Greater efforts are required in the area of emergency services and, of course, in problems related to comfort, improvement of which is easily achievable and evident with the inauguration of the new hospital
