Evaluación del paisaje de la Comunidad de Madrid: de la protección a la gestión territorial
La Comunidad de Madrid ha estimado de interés contar con una caracterización, diagnóstico y evaluación de la calidad del paisaje que permita el establecimiento de criterios de protección y ordenación del territorio, conforme a lo establecido por la Ley 9/2001, de 17 de julio, del Suelo de la Comunidad de Madrid. Como resultado del estudio llevado a cabo, se dispone de una caracterización del patrimonio paisajístico de la Comunidad a escala 1:25.000, de un diagnóstico sintético de las tendencias del paisaje por grandes conjuntos paisajísticos, y de una primera valoración de cada paisaje, que puede constituir, junto a otras variables, un criterio operativo de ordenación territorial, concretamente para la definición de suelos no urbanizables de protección por su interés paisajístico. En el artículo se incide en los aspectos metodológicos de la tipología y caracterización del paisaje madrileño a una escala pertinente para la gestión del territorio y, sobre todo, en los criterios y resultados de valoración, y en su traslación a una propuesta de regulación de usos, de acuerdo con los valores y el estado del paisaje, y con los requerimientos de la legislación urbanística de la ComunidadThe region of Madrid has deemed it of interest to have a description, diagnosis and evaluation of the landscape quality to allow the establishment of protection and zoning criteria for the territory, according to the Land Act 9/2001 of July 17. As a result of the study performed, a landscape survey of the region is available at a scale of 1:25000, as well as a description of the trends in major landscapes and a basic evaluation of each landscape.This last resource may be, together with others, a working criterion for territorial planning, particularly for the zoning of areas not available for residential development due to their landscap

Impact of Exposome Factors on Epidermal Barrier Function in Patients with Obstructive Sleep Apnea Syndrome
Exposome factors, such as sleep deprivation and diet, could affect skin barrier function. The objectives of this study are to compare skin barrier function between patients with Obstructive Sleep Apnea Syndrome (OSAS) and healthy individuals, and to evaluate the effect of other exposome factors on skin. A cross-sectional study was conducted. Patients with OSAS and healthy volunteers matched by age and sex were included. OSAS severity was assessed by the Apnea-Hypopnea Index (AHI). Validated questionnaires were used to assess diet, anxiety, depression, and psychological stress. Skin barrier function parameters including temperature, erythema, melanin, pH, transepidermal water loss (TEWL), and stratum corneum hydration (SCH) were measured on the volar forearm. A total of 86 participants were included, 56 patients with OSAS and 30 healthy volunteers. TEWL was higher in OSAS patients than in healthy individuals (8.01 vs. 8.68 g center dot m(-2)center dot h(-1)). Regarding disease severity, severe patients had higher TEWL values (9.31 vs. 8.46 vs. 7.08 g center dot m(-2)center dot h(-1)) compared to moderate and mild patients. Patients with OSAS had significantly lower sleep quality (11.89 vs. 6.47 Pittsburgh Sleep Quality Index score; p < 0.001), poor adherence to the Mediterranean Diet (8.46 vs. 9.77; p = 0.005), and significantly higher anxiety and depression levels than healthy individuals. In conclusion, patients with OSAS may have skin barrier impairment, reflected in higher TEWL values. These patients also have higher levels of anxiety, depression, stress, and a lower adherence to a Mediterranean Diet, all exposome factors that might impact on skin barrier function
Expression of epicardial adipose tissue thermogenic genes in patients with reduced and preserved ejection fraction heart failure
[Abstract] Epicardial adipose tissue has been proposed to participate in the pathogenesis of heart failure. The aim of our study was to assess the expression of thermogenic genes (Uncoupling protein 1 (UCP1), peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α), and PR-domain-missing 16 (PRDM16) in epicardial adipose tissue in patients with heart failure, stablishing the difference according to left ventricular ejection fraction (reduced or preserved). Among the 75 patients in our study, 42.7% (n=32) had reduced left ventricular ejection fraction. UCP1, PGC1α and PRDM16 mRNA in EAT were significantly lower in patients with reduced left ventricular ejection fraction. Multiple regression analysis showed that age, male gender, body max index, presence of obesity, type-2-diabetes mellitus, hypertension and coronary artery disease and left ventricular ejection fraction were associated with the expression levels of UCP1, PGC1α and PRDM16 mRNA. Thermogenic genes expressions in epicardial adipose tissue (UCP1: OR 0.617, 95%CI 0.103-0.989, p=0.042; PGC1α: OR 0.416, 95%CI 0.171-0.912, p=0.031; PRDM16: OR 0.643, 95%CI 0.116-0.997, p=0.044) were showed as protective factors against the presence of heart failure with reduced left ventricular ejection fraction, and age (OR 1.643, 95%CI 1.001-3.143, p=0.026), presence of coronary artery disease (OR 6.743, 95%CI 1.932-15.301, p<0.001) and type-2-diabetes mellitus (OR 4.031, 95%CI 1.099-7.231, p<0.001) were associated as risk factors. The adequate expression of thermogenic genes has been shown as possible protective factors against heart failure with reduced ejection fraction, suggesting that a loss of functional epicardial adipose tissue brown-like features would participate in a deleterious manner on heart metabolism. Thermogenic genes could represent a future novel therapeutic target in heart failure.Ministerio de Salud, Servicios Sociales e Igualdad; PI13/02542Ministerio de Salud, Servicios Sociales e Igualdad; PI11/01661Red de Investigación Cardiovascular (España), RD12/0042/003
On the single and multiple associations of COVID‑19 post‑acute sequelae: 6‑month prospective cohort study
Medical research is progressing to clarify the full spectrum of sub-acute and long-term effects of the
post-COVID-19 syndrome. However, most manuscripts published to date only analyze the effects
of post-COVID-19 in patients discharged from hospital, which may induce significant bias. Here, we
propose a pioneering study to analyze the single and multiple associations between post-COVID-19
characteristics with up to 6-months of follow-up in hospitalized and non-hospitalized COVID-19
patients. The cohort study was conducted from May to October 2020 at the University Hospital Virgen
de la Nieves, the leading hospital assigned for patients with COVID-19 in Granada, Spain. A total
of 372 and 217 patients—with 217 and 207 included in the first and second follow-up visits—were
referred 2 and 6 months after diagnosing COVID-19, respectively. We find out that post-COVID-19
clinical and mental health impairment symptoms are correlated with patient gender. Logistic
adjustments showed strong statistically robust single and multiple associations of demographic,
clinical, mental health, X-ray, laboratory indices, and pulmonary function variables. The functional
lung tests are good predictors of chest CT imaging abnormalities in elderly patients. Bilateral lung
involvement, subpleural reticulum, ground-glass opacity, peripheral lung lesions, and bronchiectasis
were the most common findings of the high-resolution computed tomography images. Nonhospitalized
patients suffer more severe thromboembolic events and fatigue than those hospitalized
A computer-aided diagnosis of multiple sclerosis based on mfVEP recordings.
Introduction: The aim of this study is to develop a computer-aided diagnosis system to identify subjects at differing stages of development of multiple sclerosis (MS) using multifocal visual-evoked potentials (mfVEPs). Using an automatic classifier, diagnosis is performed first on the eyes and then on the subjects.
Patients: MfVEP signals were obtained from patients with Radiologically Isolated Syndrome (RIS) (n = 30 eyes), patients with Clinically Isolated Syndrome (CIS) (n = 62 eyes), patients with definite MS (n = 56 eyes) and 22 control subjects (n = 44 eyes). The CIS and MS groups were divided into two subgroups: those with eyes affected by optic neuritis (ON) and those without (non-ON).
Methods: For individual eye diagnosis, a feature vector was formed with information about the intensity, latency and singular values of the mfVEP signals. A flat multiclass classifier (FMC) and a hierarchical classifier (HC) were tested and both were implemented using the k-Nearest Neighbour (k-NN) algorithm. The output of the best eye classifier was used to classify the subjects. In the event of divergence, the eye with the best mfVEP recording was selected.
Results: In the eye classifier, the HC performed better than the FMC (accuracy = 0.74 and extended Matthew Correlation Coefficient (MCC) = 0.68). In the subject classification, accuracy = 0.95 and MCC = 0.93, confirming that it may be a promising tool for MS diagnosis. Chirped-pulse φOTDR provides distributed strain measurement via a time-delay estimation process. We propose a lower bound for performance, after reducing sampling error and compensating phase-noise. We attempt to reach the limit, attaining unprecedented pε/√Hz sensitivities.
Conclusion: In addition to amplitude (axonal loss) and latency (demyelination), it has shown that the singular values of the mfVEP signals provide discriminatory information that may be used to identify subjects with differing degrees of the disease.Secretaría de Estado de Investigación, Desarrollo e InnovaciónInstituto de Salud Carlos II
Changes in humoral immune response after SARS-CoV-2 infection in liver transplant recipients compared to immunocompetent patients
The protective capacity and duration of humoral immunity after SARS-CoV-2 infection are not yet understood in solid organ transplant recipients. A prospective multicenter study was performed to evaluate the persistence of anti-nucleocapsid IgG antibodies in liver transplant recipients 6 months after coronavirus disease 2019 (COVID-19) resolution. A total of 71 liver transplant recipients were matched with 71 immunocompetent controls by a propensity score including variables with a well-known prognostic impact in COVID-19. Paired case-control serological data were also available in 62 liver transplant patients and 62 controls at month 3 after COVID-19. Liver transplant recipients showed a lower incidence of anti-nucleocapsid IgG antibodies at 3 months (77.4% vs. 100%, p <.001) and at 6 months (63.4% vs. 90.1%, p <.001). Lower levels of antibodies were also observed in liver transplant patients at 3 (p =.001) and 6 months (p <.001) after COVID-19. In transplant patients, female gender (OR = 13.49, 95% CI: 2.17-83.8), a longer interval since transplantation (OR = 1.19, 95% CI: 1.03-1.36), and therapy with renin-angiotensin-aldosterone system inhibitors (OR = 7.11, 95% CI: 1.47-34.50) were independently associated with persistence of antibodies beyond 6 months after COVID-19. Therefore, as compared with immunocompetent patients, liver transplant recipients show a lower prevalence of anti-SARS-CoV-2 antibodies and more pronounced antibody levels decline
The Importance of Spanish Data (BDMIN & PANORAMA MINERO) in the European Raw Materials Knowledge Base (EURMKB)
[EN] The IGME has an extensive experience in the field of mineral resources and the main source of information is the Mineral Resources Database (BDMIN) that integrates the geological‐mining information on occurrences, mines and exploitations (active and inactive) of metallic, nonmetallic and industrial minerals, and rocks in Spain. In addition, since 1981, the Panorama Minero has been carried out with the aim of providing reliable data on Spanish mining production, based on the Spanish Mining Statistics (MITERD). This information includes data on the national production of minerals, in tonnage and value, metallurgical production, foreign trade, etc. Other sources include the National Mining Cadastre and Foreign Trade statistics from the Tax Agency.Peer reviewe
