Frecuencia de desórdenes mentales en adultos mayores residentes en una institución de asistencia social en la Ciudad de México

Resumen: Antecedentes: La Organización Mundial de la Salud ha informado que en los adultos mayores se incrementará y agravará la magnitud de los problemas de salud mental, lo que estará relacionado al incremento de su expectativa de vida y al aumento de las personas que alcanzarán edades avanzadas. Objetivos: Identificar y estimar la frecuencia de desórdenes mentales en adultos mayores. Material y Método: Estudio observacional, descriptivo y transversal. Se aplicó un cuestionario que incluía variables sociodemográficas y la Mini Entrevista Neuropsiquiátrica Internacional (M.I.N.I.). Población de estudio de 60 años y más, residentes en una Institución de Asistencia Social de la Ciudad de México. La muestra se seleccionó aleatoria y sistemáticamente, eligiendo una de cada cuatro. Participó personal previamente capacitado tanto en la metodología como en los procedimientos y aplicación del instrumento. Resultados: De la población de estudio, se obtuvo una muestra ponderada de 80 entrevistas completas (67%). En su mayoría fueron femeninos y viudas, con una media de edad de 80 años y 5 de escolaridad. Encontramos ausencia en el 30%; en un 40% sólo se reportó sintomatología y en el 30% restante se cubrieron diagnósticos psiquiátricos. Conclusiones: La salud mental y los desórdenes psiquiátricos han sido escasamente conocidos y estudiados en esta población. La entrevista MINI permitió identificar y estimar la frecuencia de síntomas y diagnósticos de desórdenes mentales. Nuestra estimación (30%) fue similar a la reportada en otro estudio (29.7%). La prevención, identificación, detección e intervención oportuna a los problemas de salud mental adquieren gran importancia en este contexto. Palabras clabe: Adultos mayores. Envejecimiento. Vejez.

Abstract: Background: World Health Organization has reported that in old adults population will increase and aggravate the magnitude of mental health problems, which will be linked to the increase in his life expectancy and with the rise of individuals who reach old age. Objectives: identify and estimate the frequency of mental disorders in elderly people. Materials and Methods: Study observational, descriptive and transversal. It applies a questionnaire, which included socio-demographic variables and the Mini International Neuropsychiatric Interview (M.I.N.I.). Study population of persons aged 60 and over living in an Institution of Social Assistance in Mexico City, here were selected a systematic random sample, choosing one in four adults. The interviews were available staff previously trained in the handling of the methodology, procedures and application of the instrument Results: Out of a population study, resulting in a weighted sample of 80 completed interviews (67%). The main percentages were females and widower, with a mean age of 80 years and 5 of schooling. We find absence in the 30%, only 40% reported symptoms and the remaining 30% were filled psychiatric diagnoses. Conclusions: Mental health and psychiatric disorders has been scantily known and studied until this moment. The interview M.I.N.I. allowed us to identify and estimate their frequency of symptoms and diagnostics mental disorders. The frequency diagnostic of mental disorders found in our research (30%) is very similar to that obtained in another study (29.7%). In this context, the prevention, detection and opportune intervention for mental health problems are remarkable. Keywords: Elderly. Aging. Oldness. Mental disorders.

Relevance of gastrointestinal manifestations in a large Spanish cohort of patients with systemic lupus erythematosus: what do we know?

SLE can affect any part of the gastrointestinal (GI) tract. GI symptoms are reported to occur in >50% of SLE patients. To describe the GI manifestations of SLE in the RELESSER (Registry of SLE Patients of the Spanish Society of Rheumatology) cohort and to determine whether these are associated with a more severe disease, damage accrual and a worse prognosis. METHODS: We conducted a nationwide, retrospective, multicentre, cross-sectional cohort study of 3658 SLE patients who fulfil =4 ACR-97 criteria. Data on demographics, disease characteristics, activity (SLEDAI-2K or BILAG), damage (SLICC/ACR/DI) and therapies were collected. Demographic and clinical characteristics were compared between lupus patients with and without GI damage to establish whether GI damage is associated with a more severe disease. RESULTS: From 3654 lupus patients, 3.7% developed GI damage. Patients in this group (group 1) were older, they had longer disease duration, and were more likely to have vasculitis, renal disease and serositis than patients without GI damage (group 2). Hospitalizations and mortality were significantly higher in group 1. Patients in group 1 had higher modified SDI (SLICC Damage Index). The presence of oral ulcers reduced the risk of developing damage in 33% of patients. CONCLUSION: Having GI damage is associated with a worse prognosis. Patients on a high dose of glucocorticoids are at higher risk of developing GI damage which reinforces the strategy of minimizing glucocorticoids. Oral ulcers appear to decrease the risk of GI damage. © The Author(s) 2021. Published by Oxford University Press on behalf of the British Society for Rheumatology

HE-LHC: The High-Energy Large Hadron Collider – Future Circular Collider Conceptual Design Report Volume 4

In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100 km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100 TeV. Its unprecedented centre-of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries

Collimation method using a double grating system

We present a collimation technique based on a double grating system to locate with high accuracy an emitter in the focal plane of a lens. Talbot self-images are projected onto the second grating producing moiré interferences. By means of two photodetectors positioned just behind the second grating, it is possible to determine the optimal position of the light source for collimation by measuring the phase shift between the signals over the two photodetectors. We obtain mathematical expressions of the signal in terms of defocus. This allows us to perform an automated technique for collimation. In addition, a simple and accurate visual criterion for collimating a light source using a lens is proposed. Experimental results that corroborate the proposed technique are also presented

Neural Network-Based Self-Tuning PID Control for Underwater Vehicles

For decades, PID (Proportional + Integral + Derivative)-like controllers have been successfully used in academia and industry for many kinds of plants. This is thanks to its simplicity and suitable performance in linear or linearized plants, and under certain conditions, in nonlinear ones. A number of PID controller gains tuning approaches have been proposed in the literature in the last decades; most of them off-line techniques. However, in those cases wherein plants are subject to continuous parametric changes or external disturbances, online gains tuning is a desirable choice. This is the case of modular underwater ROVs (Remotely Operated Vehicles) where parameters (weight, buoyancy, added mass, among others) change according to the tool it is fitted with. In practice, some amount of time is dedicated to tune the PID gains of a ROV. Once the best set of gains has been achieved the ROV is ready to work. However, when the vehicle changes its tool or it is subject to ocean currents, its performance deteriorates since the fixed set of gains is no longer valid for the new conditions. Thus, an online PID gains tuning algorithm should be implemented to overcome this problem. In this paper, an auto-tune PID-like controller based on Neural Networks (NN) is proposed. The NN plays the role of automatically estimating the suitable set of PID gains that achieves stability of the system. The NN adjusts online the controller gains that attain the smaller position tracking error. Simulation results are given considering an underactuated 6 DOF (degrees of freedom) underwater ROV. Real time experiments on an underactuated mini ROV are conducted to show the effectiveness of the proposed scheme
