Teacher Support Resources, Need Satisfaction and Well-Being.
2015
AbstractBased on Job Demands-Resources Model (JD-R), this study examines the relationships among teacher support resources, psychological need satisfaction, engagement and burnout in a sample of 282 Spanish secondary school teachers. Nine teacher psychological needs were identified based on the study of Bess and on the Self-Determination Theory (SDT). Self-report questionnaires were used to measure the constructs selected for this study and their interrelationships were examined by structural equation modeling. The results reveal a good model fit to the data (NNFI = .88; CFI = .90; GFI = .90; RMSEA = .061). The analyses indicate a positive and significant effect of latent variable Psycholog…
The extent of HLA-DR expression on HLA-DR+Tregs allows the identification of patients with clinically relevant borderline rejection
2013
Regulatory T cells (Tregs) were shown to be involved into the pathogenesis of acute rejection after transplantation. The suppressive activity of the total regulatory T cell pool depends on its percentage of highly suppressive HLA-DR(+) -Treg cells. Therefore, both the suppressive activity of the total Treg pool and the extent of HLA-DR expression of HLA-DR(+) -Tregs (MFI HLA-DR) were estimated in non transplanted volunteers, patients with end-stage renal failure (ESRF), healthy renal transplant patients with suspicion on rejection, due to sole histological Bord-R or sole acute renal failure (ARF), and patients with clinically relevant borderline rejection (Bord-R and ARF). Compared to patie…
Intimate partner violence in women with disabilities: perception of healthcare and attitudes of health professionals
2017
Intimate partner violence (IPV) is a major social problem and public health issue, but we still have a relatively small amount of data about partner violence in women with disabilities. The main objective of this study was to understand the experiences of women with disabilities who are or have been abused by their partners and to explore the knowledge, views and training requirements of primary care professionals.Qualitative study using semi-structured interviews with women with disabilities who had experienced IPV (n = 14), and focus groups with healthcare professionals (n = 16).Women with disabilities suffer specific forms of abuse. Because they depend on the people around them to take a…
The obsolescent renal glomerulus ? Collapse, sclerosis, hyalinosis, fibrosis
1977
By light and electron microscopical examination it is shown that four structural components can contribute to obsolescent glomeruli: capillary basement membranes, enriched mesangium matrix, “vascular” hyalin and collagen fibers. Each of these components can bring about glomerular damage alone. One non-reactive form — a glomerular collapse with only basement membrane remnants — can be separated from three reactive forms: the accumulation of mesangium matrix (sclerosis or matrix-sclerosis), deposition of vascular hyalin (hyalinosis in the narrow sense), and fiber development within the former urinary space (fibrosis or fibro-sclerosis). The use of the term “fibrinoid” in place of the descript…
Negative biopsy of focal hepatic lesions: Decision tree model for patient management
2019
OBJECTIVE. The purpose of this study was to investigate patient- and procedure-related variables affecting the false-negative rate of ultrasound (US)-guided liver biopsy and to develop a standardized patient-tailored predictive model for the management of negative biopsy results. MATERIALS AND METHODS. We retrospectively included 389 patients (mean age ± SD, 62 ± 12 years old) who had undergone US-guided liver biopsy of 405 liver lesions between January 1, 2013, and June 30, 2015. We collected multiple patient- and procedure-related variables. By comparing pathology reports of biopsy and the reference standard (further histology or imaging follow-up), we were able to categorize the biopsy r…
Metabolite identification in human liver needle biopsies by high-resolution magic angle spinning1H NMR spectroscopy
2006
High-resolution magic angle spinning (HR-MAS) 1 H NMR spectroscopy of intact human liver needle biopsies has not been previously reported. HR-MAS NMR spectra collected on 17 specimens with tissue amounts between � 0.5 and 12 mg showed very good spectral resolution and signal-to-noise ratios. One-dimensional 1 H spectra revealed many intense signals corresponding to cellular metabolites. In addition, some high molecular weight metabolites, such as glycogen and mobile fatty acids, could be observed in some spectra. Resonance assignments for 22 metabolites were obtained by combining the analysis of three different types of 1D 1 H spectral editing, such as T2 filtering or the nuclear Overhauser…
Long-term follow-up of hepatitis C virus-positive patients with persistently normal serum transaminases
2013
Material and methods. This study prospectively evaluated the progression of liver disease in a group of anti-HCV-positive patients with persistently normal ALT levels (PNALT) who were HCV-RNA positive. Patients selected for this study were those who presented with PNALT according to the Italian Association for the Study of the Liver (AISF) criteria in the year 1995/96 and underwent liver biopsy. They were divided into two groups according to their ALT evolution. Forty-five patients were included in this study. Results. After a median follow-up time of 180 months twenty-five of them maintained PNALT, but two of these developed liver cirrhosis (LC) in a mean time of 174 and 202 months, respec…
Predicting Mortality Risk in Patients With Compensated HCV-Induced Cirrhosis: A Long-Term Prospective Study
2009
OBJECTIVES: The identification of prognostic factors associated with mortality is crucial in any clinical setting. METHODS: We enrolled in a prospective study 352 patients with compensated hepatitis C virus (HCV)-induced cirrhosis, consecutively observed between 1989 and 1992. At entry, patients underwent upper endoscopy to detect esophageal varices, and were then surveilled by serial clinical and ultrasonographic examination. The model for end-stage liver disease (MELD) score was calculated with information collected at enrollment. Baseline predictors and intercurrent events associated with mortality were assessed using the Cox regression model. RESULTS: During a median follow-up of 14.4 y…
Metastatic Anterior Chamber Non-Hodgkin Lymphoma in a Patient With Acquired Immunodeficiency Syndrome
1997
Purpose To alert ophthalmologists to the possibility of metastatic anterior chamber intraocular non-Hodgkin lymphoma in patients with acquired immunodeficiency syndrome (AIDS). Methods We examined a 19-year-old man with AIDS who had an anterior uveitis with pseudohypopyon and a history of 2 months of malaise. A specimen of the lesion was obtained with a 25-gauge needle for pathologic examination. RESULTS: Systemic exploration showed hepatomegaly. Abdominal computed tomography showed multiple lesions in the liver and spleen. Fine-needle aspiration disclosed a high-grade non-Hodgkin lymphoma. The result of a fine-needle aspiration obtained from a lesion in the anterior chamber was consistent …
Perceptions and experiences of parenthood and maternal health care among Latin American women living in Spain: A qualitative study
2013
Objective: to explore the experiences and perceptions of parenthood and maternal health care among Latin American women living in Spain. Design: an exploratory qualitative research using focus groups and thematic analysis of the discussion. Setting and participants: three focus groups with 26 women from Bolivia and Ecuador and three focus groups with 24 midwives were performed in three towns in the Valencian Community receiving a large influx of immigrants. Findings: the women interpreted motherhood as the role through which they achieve fulfilment and assumed that they were the ones who could best take care of their children. They perceived that men usually make decisions about sex and pre…
