Els Processos de bruixes com a font per a la meteorologia històrica: dades meteorològiques als processos de l'Arxiu i Biblioteca Episcopal de Vic

The scarcity or lack of systematic information about meteorology for the centuries covering the Middle Ages means that all meteorological information provided by other historical sources are useful and relevant. There are many sources that have been analysed from this point of view, but in this study we introduce a source that has been ignored until now. It is the trials and, specifically, those trials against supposed witches, focusing our study on all the documents of this type conserved in the Episcopal Archive and Library of Vic. The necessary concision that the communication provides does not enable us to make a detailed analysis of each reference or eachmeteorological fact recorded, but the essential factor is precisely to compile the references so that they can be taken into account and studied in depth in later work

Crystal structure solution of an elusive polymorph of Dibenzylsquaramide

The crystal structure of the third polymorph of dibenzylsquaramide (Portell, A. et al., 2009), (fig. 1) has been determined from laboratory X-ray powder diffraction data by means of direct space methods using the computing program FOX. (Favre-Nicolin and Černý, 2002) The structure resolution has not been straightforward due to several difficulties on the indexing process and in the space group assignment. The asymmetric unit contains two different conformers, which has implied an additional difficulty during the Rietveld (Rietveld, 1969) refinement. All these issues together with particular structural features of disquaramides are discusse

Assessing the Feasibility and Acceptability of a Primary Care Socio-Ecological Approach to Improve Physical Activity Adherence among People with Type 2 Diabetes : The SENWI Project

Ajuts: This research was funded by Col·legi de Fisioterapeutes de Catalunya (CFC), grant number R05/21.Maintaining an active lifestyle is a key health behavior in people with type 2 diabetes (T2D). This study assessed the feasibility and acceptability of a socio-ecological Nordic walking intervention (SENWI) to enhance healthy behaviors in primary healthcare settings. Participants included individuals with T2D (n = 33; age 70 (95% CI 69-74)) and healthcare professionals (HCPs, n = 3). T2D participants were randomly assigned to a SENWI, active comparator, or control group for twelve weeks. Feasibility and acceptability were evaluated based on a mixed methodology. Quantitative data reported adherence information, differences between follow-up and dropout participants and pre- and post-intervention on physical activity, sedentary behavior, and health outcomes. Qualitative data acquisition was performed using focus groups and semi-structured interviews and analyzed using thematic analysis. Thirty-three T2D invited participants were recruited, and twenty-two (66.7%) provided post-intervention data. The SENWI was deemed acceptable and feasible, but participants highlighted the need to improve options, group schedules, gender inequities, and the intervention's expiration date. Healthcare professionals expressed a lack of institutional support and resources. Nevertheless, no significant difference between the SENWI follow-up and dropout participants or pre- and post- intervention was found (only between the active comparator and control group in the physical quality of life domain). Implementing the SENWI in primary healthcare settings is feasible and acceptable in real-world conditions. However, a larger sample is needed to assess the program's effectiveness in improving healthy behaviors and its impact on health-related outcomes in the long term

The contribution of HIV point-of-care tests in early HIV diagnosis : community-based HIV testing monitoring in Catalonia, 1995 to 2018

Community-based HIV testing services combined with the use of point-of-care tests (POCT) have the potential to improve early diagnosis through increasing availability, accessibility and uptake of HIV testing. To describe community-based HIV testing activity in Catalonia, Spain, from 1995 to 2018, and to evaluate the impact of HIV POCT on the HIV continuum of care. A community-based network of voluntary counselling and testing services in Catalonia, Spain has been collecting systematic data on activity, process and results since 1995. A descriptive analysis was performed on pooled data, describing the data in terms of people tested and reactive screening test results. Between 1995 and 2018, 125,876 HIV tests were performed (2.1% reactive). Since the introduction of HIV POCT in 2007, a large increase in the number of tests performed was observed, reaching 14,537 tests alone in 2018 (1.3% reactive). Men who have sex with men (MSM), as a proportion of all people tested, has increased greatly over time reaching 74.7% in 2018. The highest percentage of reactive tests was found in people who inject drugs followed by MSM. The contribution of community-based HIV testing to the overall total notified cases in the Catalonia HIV registry has gradually increased, reaching 37.9% in 2018, and 70% of all MSM cases. In 2018, the percentage of individuals with a reactive screening test who were linked to care was 89.0%. Our study reinforces the important role that community-based HIV POCT has on the diagnosis of HIV in key populations

Disseny d'un sistema d'indicadors ambientals en camins i diagnosi socioambiental del Camí de Cavalls : sector sud-oest

Menorca va ser declarada Reserva de la Biosfera per la UNESCO l'any 1993. Entre d'altres, un dels aspectes més emblemàtics de l'Illa és el Camí de Cavalls. Preservar la diversitat que aquest ofereix comporta una gestió complexa. Per això, és necessària per una millor gestió ambiental la realització prèvia d'una diagnosi per determinar en quina situació es troba actualment el Camí, i així poder optimitzar els mecanismes de gestió de l'espai. Aquesta diagnosi té com a objectius desenvolupar un sistema d'indicadors ambientals i socioeconòmics i validar-los per avaluar els canvis que es poden donar en el litoral de Menorca en els propers anys en relació a aquest espai. Dins d'aquest marc de treball, el sistema d'indicadors dissenyat a nivell teòric ha estat validat a través d'un exhaustiu treball de camp. Amb aquest objectiu s'ha volgut crear un disseny eficient, de forma que qualsevol persona que vulgui aplicar-lo al Camí de Cavalls o en altres tipologies de camí pugui fer-ho d'una manera correcte.Nota: Aquest document conté originàriament altre material i/o programari només consultable a la Biblioteca de Ciència i Tecnologia.Aquest projecte està relacionat amb el titulat "Disseny d'un sistema d'indicadors en camins i diagnosi socioambiental del Camí de Cavalls de Menorca 2008: sector nord-est", redactat per Dídac Masana, Marta Morros i Esther Sanyé

Risk factors and outcomes of organ-space surgical site infections after elective colon and rectal surgery

Background: organ-space surgical site infections (SSI) are the most serious and costly infections after colorectal surgery. Most previous studies of risk factors for SSI have analysed colon and rectal procedures together. The aim of the study was to determine whether colon and rectal procedures have different risk factors and outcomes for organ-space SSI. Methods: a multicentre observational prospective cohort study of adults undergoing elective colon and rectal procedures at 10 Spanish hospitals from 2011 to 2014. Patients were followed up until 30 days post-surgery. Surgical site infection was defined according to the Centers for Disease Control and Prevention criteria. Oral antibiotic prophylaxis (OAP) was considered as the administration of oral antibiotics the day before surgery combined with systemic intravenous antibiotic prophylaxis. Results: of 3,701 patients, 2,518 (68%) underwent colon surgery and 1,183 (32%) rectal surgery. In colon surgery, the overall SSI rate was 16.4% and the organ-space SSI rate was 7.9%, while in rectal surgery the rates were 21.6% and 11.5% respectively (p < 0.001). Independent risk factors for organ-space SSI in colon surgery were male sex (Odds ratio -OR-: 1.57, 95% CI: 1.14-2.15) and ostomy creation (OR: 2.65, 95% CI: 1.8-3.92) while laparoscopy (OR: 0.5, 95% CI: 0.38-0.69) and OAP combined with intravenous antibiotic prophylaxis (OR: 0.7, 95% CI: 0.51-0.97) were protective factors. In rectal surgery, independent risk factors for organ-space SSI were male sex (OR: 2.11, 95% CI: 1.34-3.31) and longer surgery (OR: 1.49, 95% CI: 1.03-2.15), whereas OAP with intravenous antibiotic prophylaxis (OR: 0.49, 95% CI: 0.32-0.73) was a protective factor. Among patients with organ-space SSI, we found a significant difference in the overall 30-day mortality, being higher in colon surgery than in rectal surgery (11.5% vs 5.1%, p = 0.04). Conclusions: organ-space SSI in colon and rectal surgery has some differences in terms of incidence, risk factors and outcomes. These differences could be considered for surveillance purposes and for the implementation of preventive strategies. Administration of OAP would be an important measure to reduce the OS-SSI rate in both colon and rectal surgeries

Los objetos elaborados con fibras vegetales del Neolítico Antiguo de Coves del Fem, Ulldemolins (Tarragona)

Los objetos manufacturados con materias orgánicas raramente se conservan excepto bajo condiciones ambientales específicas, ya sea en medios de sequedad constante, en contextos anaeróbicos sumergidos, bajo congelación o por carbonización. Por ello, las técnicas de cestería y cordelería, así como las materias primas utilizadas están escasamente documentadas en el registro arqueológico del Neolítico peninsular. Se aporta aquí nueva información acerca de las técnicas cesteras y de cordelería, así como de las materias primas utilizadas en Coves del Fem (Ulldemolins, Tarragona). Estos restos fueron recuperados en una fosa adscribible al Neolítico antiguo. La cestería estudiada se encuentra manufacturada a través de la técnica de espiral cosida, mientras que en el caso de la cordelería se trata de un único fragmento torsionado. Se discute su funcionalidad en un contexto de hábitat en cueva, así como su tecnología y materias primas usadas, contextualizándolos con otros ejemplos de cestería de espiral cosida de la península ibérica.Plant-based artefacts are considered one of the first technologies used by human populations playing an important role in the daily life of all societies. Even though, they are made of perishable material which usually disappears in archaeological contexts except for some specific environmental conditions that permit their conservation as arid, anaerobic, waterlogged atmospheres or carbonization. Some examples of the f irst implements produced by organic materials are baskets and cords which are documented since the very beginning of human populations. Nevertheless, these fibre-based materials have been excluded from archaeological studies. The lack of knowledge in this vegetal technology is a consequence of the difficulty of organic material preservation and the non-suitable analysis and identification methodologies. Even they represent a living material culture as history and ethnography demonstrate, vegetal fibres were probably used for producing indispensable everyday objects and artefacts in the past. The aim of this paper is to provide new information about vegetal technology as basketry and cordage techniques, as well as the raw materials used in Neolithic chronologies in the North-East of the Iberian Peninsula. The materials analyzed in this study were recovered at the site of Coves del Fem (Ulldemolins, Tarragona) which is a rock shelter preserved thanks to the fallen rock blocks. Basketry and cordage fragments came from the archaeological fieldwork of 2019 and were recovered inside a pit in levels of the final Early Neolithic. They were preserved thanks to the carbonization and dehydration they were submitted to. Both basketry and cordage examples from Coves del Fem, were deeply described considering their morphology and technology, as well as the raw materials they were made of. The methodology consisted of describing the technique used and taking measures of the different fragments aiming to obtain information about the way the basket and the cord were made. The identification of raw materials was performed by observing cross, peridermal and longitudinal sections of samples using a transmitted optical microscope. Descriptions were based on microanatomical observation by comparing with reference modern material and specialized technical literature. The results showed the basketry assemblage was produced using the coiling technique and all the fragments belong to a single object. In the case of the cordage fragment, it was made by twisting the fibres which had been previously mechanically processed. The identification of raw materials revealed at least the use of sedges for basketry and non-identified herbaceous plants for making cordage. The functionality of the objects is discussed, and they are also contextualized with other Neolithic fibre productions examples from the Iberian Peninsula and the Middle East, both technologically and the chosen raw materials. In summary, fibre-based productions from Coves del Fem, along with the assemblage from the lake dwelling site of La Draga, fill the gap of this archaeological record from the Iberian Peninsula to Europe, demonstrating the long history of the technical skills related to plant exploitation

Statins and new-onset atrial fibrillation in a cohort of patients with hypertension: analysis of electronic health records, 2006-2015

Atrial Fibrillation; Electronic Health Records; HypertensionFibrilación atrial; Registros Electrónicos de Salud; HipertensiónFibril·lació atrial ; Registres Electrònics de Salut; HipertensióHypertension is the most prevalent risk factor for new-onset atrial fibrillation (AF). But few studies have addressed the effect of statins on the incidence of this arrhythmia in patients with hypertension. This study aimed to evaluate the effect of statins on new-onset of this arrhythmia in a hypertensive population, accounting for AF risk. Data from the Information System for the Development of Research in Primary Care was used to recruit a retrospective cohort of ≥55-year-old hypertensive individuals with no ischemic vascular disease, in 2006-2007, followed up through 2015. The effect of initiating statin treatment on new-onset atrial fibrillation was assessed with Cox proportional hazards models adjusted by the propensity score of receiving statin treatment, in the overall study population and stratified by AF risk. Of 100 276 included participants, 9814 initiated statin treatment. The AF incidence per 1000 person-years (95% confidence interval) was 12.5 (12.3-12.8). Statin use associated with a significant (9%) reduction in AF incidence. Differences in absolute AF incidence were higher in the highest AF risk subgroup, and the estimated number needed to treat to avoid one case was 720. The relative effect was poor, similar across groups, and non-significant, as was the association of statins with adverse effects. We found a limited protective effect of statins over new-onset AF in this hypertensive population with no ischemic vascular disease. If there is no further indication, hypertensive patients would not benefit from statin use solely for AF primary prevention
