Age of onset of Cannabis use and cognitive function in first-episode non-affective psychosis patients: Outcome at three-year follow-up

2018

In recent years, the effects of cannabis use on cognitive functions in patients with psychosis have been widely studied. Recently, special emphasis has been placed on the impact of age at the onset of consumption on cognition in these patients.349 patients with a first episode of non-affective psychosis were studied. Patients were classified as cannabis users and non-users. Users were divided, according to their age when they began using cannabis, into: early-onset (age  16) and late-onset (age ≥ 16) users. Differences between groups at baseline were studied based on sociodemographic, clinical, and cognitive variables. The groups were longitudinally (3-year) compared on cognitive variables.…

Personality functioning as a mediator of adult mental health following child maltreatment.

2021

Abstract Background The broad range of adverse health outcomes following child maltreatment (child maltreatment) underscores the need to investigate shared trajectories that contribute to associated physical and mental health problems. Previous research focused on different mechanisms, such as emotion regulation or attachment. In the present study, we propose personality functioning, comprising self- and interpersonal regulation and perception, to mediate between child maltreatment and mental and physical health. Methods In a German representative sample (N = 2,508), we assessed remembered child maltreatment, levels of personality functioning, and different health outcomes in adulthood, nam…

Prevalence of surrogate markers of relative energy deficiency in male Norwegian Olympic-level athletes

2021

Author's accepted manuscript. Accepted author manuscript version reprinted, by permission, from [International Journal of Sport Nutrition and Exercise Metabolism, 2021, 31(6): 497-506, https://doi.org/10.1123/ijsnem.2020-0368]. © Human Kinetics, Inc. The syndrome of Relative Energy Deficiency in Sport (RED-S) includes wide-ranging effects on physiological and psychological functioning, performance, and general health. However, RED-S is understudied among male athletes at the highest performance levels. This cross-sectional study aimed to investigate surrogate RED-S markers prevalence in Norwegian male Olympic-level athletes. Athletes (n = 44) aged 24.7 ± 3.8 years, body mass 81.3 ± 15.9 kg,…

Interictal Executive Dysfunction in Migraineurs Without Aura: Relationship With Duration and Intensity of Attacks

2007

Subjects with migraine are at increased risk of subcortical white matter lesions (WML). Reports of cognitive testing in adults with migraine have yielded inconsistent results. We performed a cross-sectional study to assess whether migraine without aura (MwA) is associated with impairment in executive functioning, a typical cognitive correlate of subcortical WML. Forty-five subjects with MwA and 90 controls, matched for age and education, underwent a cognitive battery of tests evaluating executive functions. The following migraine characteristics were collected: age at onset and length of migraine history, and frequency, duration and intensity of attacks. Subjects with MwA performed signifi…

Relationship between Meditative Practice and Self-Reported Mindfulness: the MINDSENS Composite Index

2014

Mindfulness has been described as an inherent human capability that can be learned and trained, and its improvement has been associated with better health outcomes in both medicine and psychology. Although the role of practice is central to most mindfulness programs, practice-related improvements in mindfulness skills is not consistently reported and little is known about how the characteristics of meditative practice affect different components of mindfulness. the present study explores the role of practice parameters on self-reported mindfulness skills. A total of 670 voluntary participants with and without previous meditation experience (n = 384 and n = 286, respectively) responded to an…

High incidence and increasing prevalence of MS in Enna (Sicily), southern Italy

2001

Twenty years after a first survey, a follow-up study was performed on the prevalence of MS in Enna (Sicily), southern Italy. The prevalence of definite MS rose from 53 to 120.2 per 100,000 population. The incidence of definite MS for the period 1986 to 1995 was 5.7 per 100,000 per year. The innermost part of Sicily shows an elevated prevalence of MS, second only to Sardinia in the Mediterranean area.

Automated segmentation of changes in FLAIR-hyperintense white matter lesions in multiple sclerosis on serial magnetic resonance imaging

2019

Longitudinal analysis of white matter lesion changes on serial MRI has become an important parameter to study diseases with white-matter lesions. Here, we build on earlier work on cross-sectional lesion segmentation; we present a fully automatic pipeline for serial analysis of FLAIR-hyperintense white matter lesions. Our algorithm requires three-dimensional gradient echo T1- and FLAIR- weighted images at 3 Tesla as well as available cross-sectional lesion segmentations of both time points. Preprocessing steps include lesion filling and intrasubject registration. For segmentation of lesion changes, initial lesion maps of different time points are fused; herein changes in intensity are analyz…
