    Feynman-Hibbs (FH) effective potentials constitute an appealing approach for investigations of many-body systems at thermal equilibrium since they allow us to easily include quantum corrections within standard classical simulations. In this work we apply the FH formulation to the study of NeN_N-coronene clusters (N=N= 1-4, 14) in the 2-14 K temperature range. Quadratic (FH2) and quartic (FH4) contributions to the effective potentials are built upon Ne-Ne and Ne-coronene analytical potentials. In particular, a new corrected expression for the FH4 effective potential is reported. FH2 and FH4 cluster energies and structures -obtained from energy optimization through a basin-hoping algorithm as well as classical Monte Carlo simulations- are reported and compared with reference path integral Monte Carlo calculations. For temperatures T>4T> 4 K, both FH2 and FH4 potentials are able to correct the purely classical calculations in a consistent way. However, the FH approach fails at lower temperatures, especially the quartic correction. It is thus crucial to assess the range of applicability of this formulation and, in particular, to apply the FH4 potentials with great caution. A simple model of NN isotropic harmonic oscillators allows us to propose a means of estimating the cut-off temperature for the validity of the method, which is found to increase with the number of atoms adsorbed on the coronene molecule

    El paisaje se define como “la impresión visual de una porción del espacio terrestre habitada por el hombre, cuyas características permiten considerarlo como una entidad homogénea diferente a otras” (Núñez 2.000), que representa un aspecto importante para la ordenación del territorio. A partir de la metodología de Zambrano, M. del C. y González, V. R. (modificada) es posible valorar el paisaje concluyendo en tres unidades cartográficas que diferencian la calidad visual de paisaje de modo relativo, para ello se realizó un relevamiento de los factores ambientales vinculados al paisaje, para realizar un análisis pertinente de cada componente que se seleccionaron para la valoración del paisaje

    A geografia da saúde possibilita compreender a organização espacial dos eventos em saúde, morbimortalidade e oferta dos serviços de saúde, tendo em vista que esses eventos não estão distribuídos aleatoriamente no espaço geográfico. As desigualdades espaciais na mortalidade infantil representam um importante problema de saúde pública, portanto, o objetivo do estudo foi analisar a geografia das condições obstétricas e neonatais, em pequenos municípios do Rio Grande do Sul, que integram a 16ª Coordenadoria Regional da Saúde, no período de 2010 a 2014. Foi realizado um estudo ecológico, com os indicadores relacionados aos recém-nascidos e à oferta de serviços públicos de saúde. As variáveis foram categorizadas em: sociodemográficas, assistenciais, resultantes e de cobertura dos serviços. Foi realizada a distribuição e análise espacial dos indicadores, através do Índice de Moran Global. O coeficiente de correlação de Pearson serviu para verificar associação entre as variáveis sociodemográficas e assistenciais, com as variáveis resultantes e, entre as condições de saúde e a cobertura dos serviços públicos de saúde. Os resultados possibilitaram a compreensão da geografia das condições obstétricas e neonatais, e de que forma os serviços públicos de saúde contribuíram na assistência materno-infantil

    The authors are grateful for the contribution of the physicians, pharmacists and patients of the Walter Cantídio University Hospital who collaborated in the conduction of this study.Objective: To evaluate the application of the Antimicrobial (ATM) treatment time reduction strategy in Intensive Care Units (ICU) in an Antimicrobial Stewardship Program (ASP). Method: This is a descriptive and cross-sectional study, carried out in two ICU of a university hospital in Fortaleza, Brazil, from January/2017 to January/2019. Adult patients were included, accompanied by a pharmacist, and using ATM, in which the treatment time reduction strategy was applied. The evaluation of the strategy was made through the difference between the predicted time established at the beginning of the treatment and the effective days of use of each ATM. Results: Of the 100 patients included, 51.0 % were male and 64.0 % were elderly. The respiratory system was the most frequently affected by the infections (37.4 %) and the most prevalent classes of ATM were carbapenems (23.0 %) and glycopeptides (20.1 %). There was a decrease from 831 unnecessary days of antimicrobial therapy and from an average of 13.7 to 8.9 days of treatment. The greatest reductions in days were observed for meropenem, with 202 days reduced. The study also allowed the identification of associations between the reduction > 8 days of treatment and the variables length of stay > 22 days and patients in exclusive palliative care, and associations between hospi tal discharge and reductions of up to 7 days of therapy. Conclusions: The data obtained suggest that the presence of an ASP influences the practices of ATM use and its treatment time and emphasize the role of pharmaceutical professionals in these programs.Objetivo: Evaluar la aplicación de la estrategia reducción del tiempo de tratamiento Antimicrobiano (ATM) en Uni dades de Cuidados Intensivos (UCI) en un Programa Stewardship de Antimicrobiano (ASP). Método: Este es un estudio descriptivo y transversal, realizado en dos UCI de un hospital universitario de Fortaleza, Brasil, de enero/2017 a enero/2019. Se incluyeron pacientes adultos, acompañados por un farmacéutico y utilizan do ATM, en los que se aplicó la estrategia de reducción del tiempo de tratamiento. La evaluación de la estrategia se realizó a través de la diferencia entre el tiempo previsto establecido al inicio del tratamiento y los días efectivos de uso de cada ATM. Resultados: De los 100 pacientes incluidos, 51,0 % eran del sexo masculino y 64,0 % ancianos. El sistema respira torio fue el más frecuentemente afectado (37,4 %) y las clases de ATM más prevalentes fueron los carbapenémicos (23,0 %) y los glicopéptidos (20,1 %). Hubo una disminución de 831 días innecesarios de terapia antimicrobiana y de un promedio de 13,7 a 8,9 días de tratamiento. Las mayores reducciones en días se observaron para meropenem, con 202 días reducidos. El estudio también permitió identificar asociaciones entre la reducción > 8 días de trata miento y las variables estancia > 22 días y pacientes en cuidados paliativos exclusivos; y asociaciones entre alta hospitalaria y reducciones de hasta 7 días de terapia. Conclusiones: Los datos obtenidos sugieren que la presencia de un ASP influye en las prácticas de uso de ATM y su tiempo de tratamiento y enfatizan el papel de los profesionales farmacéuticos en estos programa

    Background and objectives: This is the first multi-center study intended to document the prevalence, characteristics, and associations of depression in Medicine patients at the time of hospital discharge and their referral to Primary Care (PC). Methods: Adult patients randomly selected among consecutive admissions to Medicine wards in 8 hospitals in Spain, covering health districts, were examined in a two-phase ''case-finding'' procedure. Standardized, Spanish versions of instruments were used, including the Standardized Polyvalent Psychiatric Interview (SPPI) and Cumulative Illness Rating Scale (CIRS). Cases of depression were diagnosed according to ICD-10 general hospital research criteria. Results: Three hundred and twelve patients with treatable depression and 777 non-depressed controls were identified. In a conservative estimate, the global prevalence of major depression was 7.1%, dysthymia 4.2% and adjustment depression 7.1%, and 51.9% of cases were of moderate/ severe intensity. Depression was more frequent in women, the differences being significant in all categories of depression. The prevalence of depression was lower in individuals aged 85 or more years, the differences being significant in cases of both dysthymia and adjustment depression. A clear pattern of decreasing prevalence with age was observed in women. The depressed had as an average five medical systems affected, and higher CIRS scores compared with the controls, the differences being significant in cases of both major depression and dysthymia. Conclusions: This is the first report showing a considerable prevalence of treatable cases of depression in Medicine patients at the time of hospital discharge and referral to PC. Depression is associated with the severity of the medical condition, and differences observed by age and sex have clinical implications.

    The influence of pharmacotherapeutic follow-up (PTF) on quality of life was evaluated in 45 HIV+ patients, who were undergoing initial antiretroviral therapy at a specialized care center in northeast Brazil. PTF lasted nine months and quality of life was analyzed at the 1st and 9th meetings using a questionnaire validated for Brazil. The study identified 643 problems related to antiretrovirals and there were 590 pharmaceutical interventions during the PTF. The comparative analysis between the results of the 1st and the 9th meeting was statistically significant for all domains of the questionnaire. For asymptomatic patients, only one domain was statistically significant. For symptomatic patients, six domains were significant. Patients with one year of HIV/AIDS diagnosis had statistically significant differences in five domains. The results suggest that the PTF contributed to improving quality of life, particularly for symptomatic patients and those diagnosed for at least one year - important target groups for Pharmaceutical Treatment.A influência do seguimento farmacoterapêutico (SFT) sobre a qualidade de vida foi avaliada em 45 pacientes HIV+ assistidos em serviço de atendimento especializado do nordeste brasileiro. O SFT teve duração de 9 meses e a qualidade de vida foi analisada no 1º e 9º encontros através de questionário validado no País. Identificaram-se 643 problemas relacionados aos antirretrovirais e realizaram-se 590 intervenções farmacêuticas durante o SFT. A análise comparativa entre os resultados de qualidade de vida do 1º e 9º encontro foi estatisticamente significativa em todos os domínios do questionário. Quando analisados somente os pacientes assintomáticos, apenas um domínio apresentou significância estatística. Entre os sintomáticos, seis domínios foram significativos. Pacientes com até um ano de diagnóstico de HIV/AIDS apresentaram validade estatística em cinco domínios. Os resultados sugerem que o SFT contribuiu para a melhoria da qualidade de vida dos pacientes, sobretudo dos sintomáticos e/ou com até um ano de diagnóstico, representando grupos-alvo para a prática da Atenção Farmacêutica
