    Objectives To analyse the association between the type of work (productive vs reproductive work) and the levels of physical activity and sedentary behaviour in women with fibromyalgia. Method This cross-sectional study involved 258 women with fibromyalgia from southern Spain. Of them, 55% performed reproductive work (unpaid, associated with caregiving and domestic roles) exclusively, while 45% had productive job (remunerated, that results in goods or services). Physical activity of light, moderate and vigorous intensity in the leisure time, at home, at work, and totally were measured through the leisure time physical activity instrument and with the physical activity at home and work instrument, respectively. Sedentary behaviour was measured by the Sedentary Behaviour Questionnaire. Results After adjusting for age, fat percentage, education level and marital status, the multivariate analysis of covariance model informed the existence of significant differences between type of work groups (p<0.001). Women with productive work engaged in more light physical activity at work (mean difference =448.52 min; 95 % CI 179.66 to 717.38; p=0.001), and total physical activity of light (809.72 min; 535.91 to 1085.53; p<0.001) and moderate (29

    The Imaging Magnetograph eXperiment (IMaX) is a spectropolarimeter built by four institutions in Spain that flew on board the Sunrise balloon-borne telesocope in June 2009 for almost six days over the Arctic Circle. As a polarimeter IMaX uses fast polarization modulation (based on the use of two liquid crystal retarders), real-time image accumulation, and dual beam polarimetry to reach polarization sensitivities of 0.1%. As a spectrograph, the instrument uses a LiNbO3 etalon in double pass and a narrow band pre-filter to achieve a spectral resolution of 85 mAA. IMaX uses the high Zeeman sensitive line of Fe I at 5250.2 AA and observes all four Stokes parameters at various points inside the spectral line. This allows vector magnetograms, Dopplergrams, and intensity frames to be produced that, after reconstruction, reach spatial resolutions in the 0.15-0.18 arcsec range over a 50x50 arcsec FOV. Time cadences vary between ten and 33 seconds, although the shortest one only includes longitudinal polarimetry. The spectral line is sampled in various ways depending on the applied observing mode, from just two points inside the line to 11 of them. All observing modes include one extra wavelength point in the nearby continuum. Gauss equivalent sensitivities are four Gauss for longitudinal fields and 80 Gauss for transverse fields per wavelength sample. The LOS velocities are estimated with statistical errors of the order of 5-40 m/s. The design, calibration and integration phases of the instrument, together with the implemented data reduction scheme are described in some detail.Comment: 17 figure

    Background The al-Andalus physical activity intervention study is a randomised control trial to investigate the effectiveness of a land- and water-based exercise intervention for reducing the overall impact of fibromyalgia (primary outcome), and for improving tenderness and pain-related measures, body composition, functional capacity, physical activity and sedentary behaviour, fatigue, sleep quality, health-related quality of life, and cognitive function (secondary outcomes) in women with fibromyalgia. Methods/Design One hundred eighty women with fibromyalgia (age range: 35-65 years) will be recruited from local associations of fibromyalgia patients in Andalucía (Southern Spain). Patients will be randomly assigned to a usual care (control) group (n = 60), a water-based exercise intervention group (n = 60) or a land-based exercise intervention group (n = 60). Participants in the usual care group will receive general physical activity guidelines and participants allocated in the intervention groups will attend three non-consecutive training sessions (60 min each) per week during 24 weeks. Both exercise interventions will consist of aerobic, muscular strength and flexibility exercises. We will also study the effect of a detraining period (i.e., 12 weeks with no exercise intervention) on the studied variables. Discussion Our study attempts to reduce the impact of fibromyalgia and improve patients' health status by implementing two types of exercise interventions. Results from this study will help to assess the efficacy of exercise interventions for the treatment of fibromyalgia. If the interventions would be effective, this study will provide low-cost and feasible alternatives for health professionals in the management of fibromyalgia. Results from the al-Andalus physical activity intervention will help to better understand the potential of regular physical activity for improving the well-being of women with fibromyalgia.This study was supported by the Consejeria de Turismo, Comercio y Deporte (CTCD-201000019242-TRA), the Spanish Ministry of Science and Innovation (I + D + I DEP2010-15639, grants: BES-2009-013442, BES-2011-047133, RYC-2010-05957, RYC-2011-09011), the Swedish Heart-Lung Foundation (20090635), the Spanish Ministry of Education (AP-2009-3173), Granada Research of Excelence Initiative on Biohealth (GREIB), Campus BioTic, University of Granada, Spain and European University of Madrid.

    Public health emergencies, such as the current SARS-CoV-2 coronavirus pandemic, have led to tragic resource constraints that prevent lives from being saved. This has led to tensions in patient-centered care as the backbone of the system in normal conditions and the same care in emergencies originating in the COVID-19. In this review we address some of the healthcare, organizational and ethical problems that this scenario has caused in primary care such as: cancellation of programmed activities; scarce home care and follow-up of elderly, chronically ill and immobilized patients; shortage of PPE and the exposure to risk of healthcare professionals, and finally the problems associated with telemedicine and telephone attention to patients

    The testicles are the male gonad where sperm develop. Once produced, they must mature in their transit through the epididymis, where they are stored until ejaculation occurs. Sometimes, we do not find sperm in the ejaculate, a situation called azoospermia. Azoospermia may be the result of obstruction of the spermatic pathways or due to a partial or total blockage of spermatogenesis. In these situations, it is necessary to Access the testicle to confirm the cause of azoospermia or try to obtain sperm from both the testis and the epididymis. For this, different surgical techniques are described in the present work. In addition to the cases of azoospermia, there is an open debate about the posible indication of embryo biopsy techniques in males with high rates of sperm DNA fragmentation, so were view the main existing scientific evidence.Los testículos son la gónada masculina donde se desarrollan los espermatozoides. Una vez producidos, estos deben madurar en su tránsito por el epidídimo, donde son almacenados hasta que se produce la eyaculación. En ocasiones, en el eyaculado no encontramos espermatozoides, situación denominada azoospermia. La azoospermia puede ser fruto de una obstrucción de las vías espermáticas o deberse a un bloqueo parcial o total de la espermatogénesis. En estas situaciones se hace necesario acceder al testículo para confirmar la causa de la azoospermia, o bien tratar de obtener espermatozoides tanto del testículo como del epidídimo. Para ello existen diferentes técnicas quirúrgicas que son descritas en el presente trabajo. Además de los casos de azoospermia, existe un debate abierto sobre la posible indicación de las técnicas de biopsia embrionaria en varones que presentan altas tasas de fragmentación del DNA espermático, por lo que realizamos una revisión al respecto con las principales evidencias científicas existentes

    Introducción: Entre los pacientes infectados por el VIH el recuento linfocitario y fundamentalmente la carga viral, son los mejores predictores al estado definitorio de SIDA o muerte. Objetivo: analizar los factores asociados a la evolución delrecuento de linfocitos CD4 y carga viral en reclusos en tratamiento con antirretrovirales. Métodos: Se realizó un estudio de cohorte fija a reclusos VIH positivos en tratamiento con antirretrovirales de tres prisiones españolas. La adherencia al tratamiento antirretroviral se midió a través del cuestionario SMAQ. Para analizar la evolución de los parámetros clínicos de CD4 y carga viral se realizaron dos modelos de regresión lineal multinivel de efectos fijos. Resultados: El 10% eran mujeres, el 42% refirió padecer ansiedad o depresión en la última semana y el 46,6% refirió tener apoyo social dentro de la prisión. En cuanto a la media de los parámetros clínicos de log10 CD4 y log10 carga viral fueron de 2,48 y 2,89 respectivamente, teniendo el 38,6% carga viral indetectable. Se encontró una relación inversa entre la carga viral y el recuento de linfocitos CD4 (p<0,001). En cuanto a la carga viral plasmática aquellos reclusos sin morbilidad psíquica mostraron una reducción significativa (p=0,017) de la misma. Conclusiones: se pone de manifiesto la importancia de los factores psicosociales en el sistema inmunitario.<br>Introduction: Among HIV positive patients the CD4 lymphocyte count, especially the viral load, are the best predictors for progress to full blown AIDS or death. Objective: To analyze the factors associated with progress of the CD4 lymphocyte count and viral load in prison inmates in antiretroviral treatment. Methods: A fixed cohort study was conducted with HIV positive inmates receiving antiretroviral therapy in three Spanish prisons. Adherence to antiretroviral treatment was assessed with the SMAQ questionnaire. To analyze the progress of CD4 and viral load clinical parameters, two fixed effect multilevel linear regression models were utilised. Results: 10% of the sample were women, 42% referred for anxiety or symptoms of depression in the final week, and 46.6% reported having social support inside the prison. CD4 and viral load clinical parameter means were 2.48 and 2.89 respectively, and 38.6% had an undetectable viral load. A negative correlation between viral load and CD4 lymphocyte count (p<0.001) was found. Those inmates who did not present psychological morbidity showed a significant reduction in plasma viral load (p=0.017). Conclusions: The results of this study show the relevance of psychosocial factors in the immune system

    Heart failure (HF) is the leading cause of hospitalization for aging populations in Western countries, and is showing an increasing mortality. The aim of this study was to assess the probable long-term mortality risk factors for patients admitted because of HF. Retrospective study of a cohort of 202 patients consecutively hospitalized because of HF and followed up for a maximum period of 5 years. Clinical and epidemiological factors and their relationship to in-hospital and long-term mortality were analyzed. In-hospital mortality was 16%.The independent predictors were: age >75 years (HR?=?2.68, 95%?IC: 1.65-4.36, p?=?0.001); cognitive impairment (HR?=?2.77, 95%?IC: 1.40-5.48, p?=?0.004); Barthel index =60 (HR?=?0.54, 95%?IC: 0.37-0.78, p?=?0,009); creatinine levels >1.16 mg/dl at admission (HR?=?1.57, 95%?IC: 1.12-2.20, p?=?0.009); and number of diagnostics >10 on discharge (HR?=?1. 64, 95%?IC: 1.14-2.36, p?=?0.007). Accumulated mortality at 12, 24, 36 and 48 months after hospital discharge were 43%, 51%, 67% and 70%, respectively; the independent predictors for this were: age >75 years (HR?=?2.55, 95%?IC: 1.56-4.15, p?75 years (HR?=?2.68, 95%?IC: 1.65-4.36, p?=?0.001); cognitive impairment (HR?=?2.77, 95%?IC: 1.40-5.48, p?=?0.004); Barthel index =60 (HR?=?0.54, 95%?IC: 0.37-0.78, p?=?0,009); creatinine levels >1.16 mg/dl at admission (HR?=?1.57, 95%?IC: 1.12-2.20, p?=?0.009); and number of diagnostics >10 on discharge (HR?=?1. 64, 95%?IC: 1.14-2.36, p?=?0.007).

    Toward increased applicability of ultrasound contrast agents

    Ultrasound is one of the most widely used modalities in medical imaging because of its high cost-effectiveness, wide availability in hospitals, generation of real-time images, and use of nonionizing radiation. However, the image quality can be insufficient in some patients. Introducing a contrast agent (CA), which comprises a suspension of 2–6 mm-sized microbubbles, improves the image quality and thus the image analysis. At present, contrast-enhanced ultrasound is frequently used during standard clinical procedures such as kidney, liver, and cardiac (echocardiography) imaging. Multimodality and targeted imaging are future areas for ultrasound CAs. Multimodality imaging may improve diagnostics by simultaneously providing anatomical and functional information. Targeted imaging may allow for identification of particular diseases. The work within this thesis focused mainly on a novel multimodal polymer-shelled CA with the potential to be target specific. In Study I, the acoustic response was determined in a flow phantom by evaluating the contrast-to-tissue-ratio when using contrast sequences available in clinical ultrasound systems. This study showed that a high acoustic pressure is needed for optimal visualization of the polymer-shelled CA. In Study II, the in vivo performance of this CA was evaluated in a rat model, and the blood elimination time and subcellular distribution were determined. In Study III, the efficiency in endocardial border delineation was assessed in a pig model. The polymer-shelled CA had a significantly longer blood circulation time than the commercially available CA SonoVue, which is favorable for target-specific CA, in which a long circulation time increases the probability of target-specific binding. Transmission electron microscopic analysis of tissue sections from liver, kidney, spleen and lungs, obtained at different time points after CA injection showed that macrophages were responsible for the elimination of the polymer-shelled CA. A higher dose of the polymer-shelled CA was needed to obtain similar endocardial border delineation efficiency as that obtained using SonoVue. The results of Studies I–III demonstrate that the polymer-shelled CA has potential applicability in medical imaging. Current guidelines for contrast-enhanced echocardiography are limited to cases of suboptimal image quality or when there is a suspicion of structural abnormalities within the left ventricle. It may be hypothesized that the wider use of contrast-enhanced echocardiography may help to detect some diseases earlier. Study IV assessed the diagnostic outcomes after contrast administration in patients without indications for CA use. The myocardial wall motion score index and ejection fraction were evaluated by experienced and inexperienced readers, and a screening for left ventricular structural abnormalities was performed. More cases of wall motion and structural abnormalities were detected in the contrast-enhanced analysis. Intra- and interobserver variability was lower with the use of CAs. This study suggests that the more widespread use of CAs instead of the current selective approach may contribute to earlier detection of cardiovascular disease.QC 20150401</p
