Causal relationship of hepatic fat with liver damage and insulin resistance in nonalcoholic fatty liver
2017
Abstract Background and Aims Nonalcoholic fatty liver disease is epidemiologically associated with hepatic and metabolic disorders. The aim of this study was to examine whether hepatic fat accumulation has a causal role in determining liver damage and insulin resistance. Methods We performed a Mendelian randomization analysis using risk alleles in PNPLA3, TM6SF2, GCKR and MBOAT7, and a polygenic risk score for hepatic fat, as instruments. We evaluated complementary cohorts of at‐risk individuals and individuals from the general population: 1515 from the liver biopsy cohort (LBC), 3329 from the Swedish Obese Subjects Study (SOS) and 4570 from the population‐based Dallas Heart Study (DHS).

Hormonal Alterations in Victimized Women Explained by Their Hostile Reactions in Coping with Couple Violence
2019
AbstractRecent studies have highlighted the dysregulation of hypothalamic-pituitary-adrenal (HPA) axis activity and its end products, cortisol and dehydroepiandrosterone (DHEA), in women with a history of intimate partner violence (IPV) victimization. These studies analyzed several coping styles, but they neglected to examine the use of violent strategies to confront IPV and the way these strategies affect HPA functioning. This latter proposal would be based on the gender symmetry model of IPV, which sustains that IPV is generally symmetrical, but that women’s violence tends to be a reaction to male violence. Hence, the main objective of the present study was to examine whether women’s viol…
Size invariance in visual number discrimination
1991
This study deals with the observer's ability to discriminate the numerosity of two random dot-patterns irrespective of their relative size. One of these two patterns was a reference one that was always composed of 32 dots randomly distributed within a K x K invisible square window (K = 1.92 degrees). The second one was the test pattern with one of the five magnifications (K = 0.64 degrees, 1.28 degrees, 1.92 degrees, 2.56 degrees, 3.20 degrees) and the relative number of dots varied on 11 levels (N = -15, -12, -9, -6, -3, 0, 3, 6, 9, 12, or 15 dots). The observer's task was to indicate which of the two patterns contained more dots. The results show that the stimulus size, as an irrelevant s…
Blood coagulation factor XII drives adaptive immunity during neuroinflammation via CD87-mediated modulation of dendritic cells
2016
Aberrant immune responses represent the underlying cause of central nervous system (CNS) autoimmunity, including multiple sclerosis (MS). Recent evidence implicated the crosstalk between coagulation and immunity in CNS autoimmunity. Here we identify coagulation factor XII (FXII), the initiator of the intrinsic coagulation cascade and the kallikrein–kinin system, as a specific immune cell modulator. High levels of FXII activity are present in the plasma of MS patients during relapse. Deficiency or pharmacologic blockade of FXII renders mice less susceptible to experimental autoimmune encephalomyelitis (a model of MS) and is accompanied by reduced numbers of interleukin-17A-producing T cells.…
Increased structural white and grey matter network connectivity compensates for functional decline in early multiple sclerosis
2016
Background: The pathology of multiple sclerosis (MS) consists of demyelination and neuronal injury, which occur early in the disease; yet, remission phases indicate repair. Whether and how the central nervous system (CNS) maintains homeostasis to counteract clinical impairment is not known. Objective: We analyse the structural connectivity of white matter (WM) and grey matter (GM) networks to understand the absence of clinical decline as the disease progresses. Methods: A total of 138 relapsing–remitting MS patients (classified into six groups by disease duration) and 32 healthy controls were investigated using 3-Tesla magnetic resonance imaging (MRI). Networks were analysed using graph the…
Phenotype and natural history of inherited neuropathies caused byHSJ1c.352+1G>A mutation
2015
Mutations in the HSJ1 ( Heat-Shock Protein J1 ) gene, also called DNAJB2 (DnaJ (Hsp40) homologue, subfamily B, member 2), have been recently described as a cause of hereditary neuropathies. The HSJ1 c.352+1G>A mutation in homozygote state has been reported as the causative mutation in a single family with autosomal recessive distal hereditary motor neuropathy (dHMN).1 Since then, two other families with different HSJ1 mutations have been described: one with a dHMN phenotype and the other with a Charcot-Marie-Tooth disease type 2 (CMT2) phenotype.2 We identified the HSJ1 c.352+1G>A mutation in 10 patients who underwent long-lasting follow-up. We describe their phenotype and clinical evolutio…
Observational Prospective Natural History of Patients with Sanfilippo Syndrome Type B
2017
To evaluate the natural course of disease progression in patients with Sanfilippo syndrome type B (mucopolysaccharidosis type IIIB), identify potential end points for future therapy trials, and characterize biomarkers related to the disease.A prospective, multicenter study was conducted. Baseline, 6-month, and 12-month assessments included neurodevelopmental status (Bayley Scales of Infant Development, Third edition), adaptive status (Vineland Adaptive Behavior Scales, Second Edition), volumetric brain magnetic resonance imaging, cerebrospinal fluid heparan sulfate, and urine glycosaminoglycan (GAG) measurements.Nineteen patients aged 1.6-31.7 years were enrolled. Over 12 months, cognition,…
The role of meaning in gastric cancer patients: relationships among meaning structures, coping, and psychological well-being
2019
Background and Objectives: Research demonstrates that the experience of cancer invariably violates patients' meaning structures, prompting them to use coping strategies to alleviate stress and enhance well-being. The current study aimed to examine the mediating effects of coping strategies in the relationship between global and situational meaning and psychological well-being in gastric cancer patients. Design and Method: One hundred eighty-seven patients (96 women and 91 men) with gastric cancer completed questionnaires measuring meaning in life, changes of beliefs and goals, coping, and psychological well-being. Participants were between 27 and 82 years of age. They were diagnosed with ga…
Keep your eyes open: dispositional vigilance moderates the relationship between operational police stress and stress symptoms.
2017
ABSTRACTBackground: Vigilant coping is characterized by a deep processing of threat-related information. In many cases, vigilant coping increases stress symptoms, whereas avoidant coping decreases negative affect. However, vigilance may be beneficial when stress-eliciting situations involve a risk of injury or escalation as is usually the case in police operations. Design: We investigated the roles of vigilance and cognitive avoidance in police operations in a cross-sectional survey. Methods: The participants were 137 students (104 men, Mage = 28.54, SD = 8.04) from the Federal University of Applied Administrative Sciences; 76 of them were already police officers (work experience: M = 12.59…
Adaptive emotion regulation mediates the relationship between self-compassion and depression in individuals with unipolar depression
2015
Objectives To identify the mechanisms involved in the association between self-compassion and depression, we examined whether adaptive emotion regulation would mediate the relationship between self-compassion and depression in individuals with unipolar depression. Furthermore, we explored which specific emotion regulation skills would be most important in this relationship. Design and method Sixty-nine individuals with unipolar depression were assessed with the Self-Compassion Scale and the Emotion Regulation Skills Questionnaire at baseline and with the Beck Depression Inventory-II 1 week later. Results The results showed that successful application of emotion regulation skills mediates th…
