Biocrusts and catchment asymmetry in Tabernas Desert (Almeria, Spain)

2022

Abstract Catchment asymmetry is a fairly frequent phenomenon on a global scale but the main causes leading to its formation are still not well understood. Where the intervention of structural or tectonic causes is not relevant, asymmetry seems to result from differential erosion between opposite slopes that flow into the same channel, which is frequently associated with contrasted biocrust and/or vegetation covers. Biocrusts are known to be important surface stabilizing agents. However, their geomorphological consequences at the landscape scale are little known. In this study we combined field measurements with digital elevation models and image analysis to determine whether catchment asymm…

The Social Phobia and Anxiety Inventory: Psychometric Properties in a Spanish Sample

2007

This study is a validation of the Spanish version of the Social Phobia and Anxiety Inventory using a nonclinical sample (198 participants) and a clinical sample (72 participants with social phobia). The factor structure and concurrent validity with Fear of Negative Evaluation and Social Avoidance and Distress scales were analyzed. The Social Phobia and Anxiety Inventory demonstrated good concurrent validity, showing statistically significant relationships with Fear of Negative Evaluation and Social Avoidance and Distress. Results confirmed the rationale for the division of the SPAI into two subscales. Results also demonstrated the utility of the Social Phobia and Anxiety Inventory for diff…

Multiple sclerosis in southern Europe: Monreale City, Italy. A twenty-year follow-up incidence and prevalence study.

2004

BACKGROUND: Several follow-up studies showed increasing prevalence and incidence rates for multiple sclerosis (MS). OBJECTIVE:To ascertain, throughout a follow-up study, the incidence and prevalence of MS in the city of Monreale, Sicily, southern Italy. METHODS:We calculated crude and age- and sex-specific prevalence rates on December 31, 2000, and determined incidence rates for the period January 1, 1992 to December 31, 2000. RESULTS:The prevalence of MS was 71.2 per 100,000 population (48,5/100,000 in men; 93,0/100,000 in women). The incidence rate of MS for the period 1992-2000 was 4.0/100,000 per year. CONCLUSION:This study showed a nonsignificant increase in MS incidence rates in Monre…

Migraine history and migraine-induced stroke in the Dijon stroke registry.

1999

Two thousand three hundred and eighty-nine patients with first-ever stroke were registered in the population-based Dijon Stroke Registry over an 11-year period. There was a history of migraine in 49 cases (2%), with a majority of women (2.8% versus 1.1% men) with the following distribution: 27 cases among 1,380 large-artery cerebral infarctions (1.9%), 6 cases among 358 small-artery cerebral infarctions (1.6%), 6 cases among 412 cerebral infarctions due to cardiac embolism (1.4%), 7 cases among 191 cerebral hemorrhages (3.6%) and 3 cases among 47 subarachnoid hemorrhages (6.3%). The male/female ratio was 0.58 for the 49 strokes with a history of migraine versus 1.27 for the 2,340 strokes wi…

Two-year outcome in first-episode psychosis treated according to an integrated model. Is immediate neuroleptisation always needed?

2000

SummaryIn this multicentre study the two-year outcome of two groups of consecutive patients (total N = 106) with first-episode functional non-affective psychosis, both treated according to the ‘need-specific Finnish model’, which stresses teamwork, patient and family participation and basic psychotherapeutic attitudes, was compared. No alternative treatment facilities were available in the study sites. The two study groups differed in the use of neuroleptics: three of the sites (the experimental group) used a minimal neuroleptic regime whilst the other three (the control group) used neuroleptics according to the usual practice. Total time spent in hospital, occurrence of psychotic symptoms …

Trends in Incidence and Transmission Patterns of COVID-19 in Valencia, Spain

2021

Importance Limited information on the transmission and dynamics of SARS-CoV-2 at the city scale is available. Objective To describe the local spread of SARS-CoV-2 in Valencia, Spain. Design, Setting, and Participants This single-center epidemiological cohort study of patients with SARS-CoV-2 was performed at University General Hospital in Valencia (population in the hospital catchment area, 364 000), a tertiary hospital. The study included all consecutive patients with COVID-19 isolated at home from the start of the COVID-19 pandemic on February 19 until August 31, 2020. Exposures Cases of SARS-CoV-2 infection confirmed by the presence of IgM antibodies or a positive polymerase chain reacti…

Predicting relapse after a first episode of non-affective psychosis: A three-year follow-up study

2011

Preventing relapse during the first years of illness has a critical impact on lifelong outcomes in schizophrenia. A better understanding and improvement in factors which influence relapse should diminish the risk of relapse and consequently improve the outcome of the illness.To identify factors associated with relapse after 3 years of a first episode in a sample of non-affective psychosis patients who are representative of clinical practice in an epidemiological catchment.We analyzed socio-demographic and clinical data from a cohort of patients who were treated in a specialized early intervention service and who were at risk of relapse during a 3-year follow-up. Univariate analyses, logisti…

An approach to lithic raw material procurement at the middle Palaeolithic site Abrigo de la Quebrada (Chelva, Valencia)

2011

We offer a preliminary characterisation of the lithic raw-materials found in levels I-III of the Middle Paleolithic site of Abrigo de la Quebrada. The artifacts were excavated in the field seasons of 2004 and 2007, have already been the object of a preliminary technological assessment (Villaverde et al. 2008), and their analysis has been preceded by a survey of local procurement sources, carried out in 2008. We present, in a regional context, the different raw-material categories recognized (by means of a macroscopic study), and variants thereof, and we describe the different outcrops identified. Based on these data, we attempt a preliminary assessment of the resource catchments and mobilit…
