The moderating effects of vigilance on other components of attentional functioning.
2018
Abstract Background Previous research suggested that vigilance may moderate the functioning of other attentional components. However, vigilance is usually neglected when comparing the attentional functioning between groups of clinical and/or healthy participants. New method We combined data from several studies using the Attention Network Test for Interactions and Vigilance (ANTI-V), which includes a vigilance measure plus phasic alertness, orienting, and executive control scores. We estimated, for the first time, the reliability of the vigilance performance indices in the ANTI-V, by analyzing split-half correlations of 10,000 permutations of the trials. In addition, we tested whether a dif…
Differences in false recollection according to the cognitive reserve of healthy older people
2016
We present an associative recognition experiment comparing three samples of healthy people (young people, older people with high cognitive reserve [HCR], and older people with low cognitive reserve [LCR], with each sample consisting of 40 people), manipulating stimuli repetition during the study phase. The results show significant differences among the three samples in their overall performance. However, these differences are not due to a different use of familiarity, but rather due to a different way of using recollection: although there are no differences in the hit rates between the HRC and LRC samples, the LCR group makes significantly more recollective false alarms than the HCR group. …
Life satisfaction, anxiety, depression and resilience across the life span of men
2009
To determine (a) the relationship between life satisfaction, anxiety, depression and ageing in the male community and (b) to identify the impact of vulnerability factors, personal and social resources on life satisfaction and distress.A stratified random sample of the German male population (N = 2144) was investigated by standardized questionnaires of life satisfaction (FLZ(M)), depression, anxiety (PHQ), resilience (RS-11) and self-esteem (RSS).No age-related change was found regarding overall life satisfaction. Satisfaction with health decreased in midlife (51-60 years), while the importance of health increased. Importance of and satisfaction with partnership and sexuality were only reduc…
Comparing subjective intoxication with risky single-occasion drinking in a European sample.
2020
In most epidemiological literature, harmful drinking—a drinking pattern recognized as closely linked to alcohol-attributable diseases—is recorded using the measure risky single-occasion drinking (RSOD), which is based on drinking above a certain quantity. In contrast, subjective intoxication (SI) as an alternative measure can provide additional information, including the drinker’s subjective perceptions and cultural influences on alcohol consumption. However, there is a lack of research comparing both. The current article investigates this comparison, using data from the Standardized European Alcohol Survey from 2015. We analysed the data of 12,512 women and 12,516 men from 17 European coun…
Alexithymia and Adult Attachment: Investigating the Mediating Role of Fear of Intimacy and Negative Mood Regulation Expectancies
2021
Literature suggests an association between alexithymia and insecure adult attachment, but the mediation factors involved in this relationship are under-investigated. The study was carried out to test the possible mediation roles of the fear of intimacy and negative mood regulation expectancies in explaining this relationship. A convenience sample of 258 Polish adults (mean age: 30; 45% male), completed self-reporting measures related to adult attachment (RAAS), alexithymia (TAS-20), fear of intimacy (FIS) and negative mood regulation expectancies (NMRE). The results showed that alexithymia directly and indirectly predicts insecure adult attachment. Alexithymia positively predicts the fear …
Problems in the management of chronic hepatitis B with interferon: experience in a randomized, multicentre study.
1990
In a multicentre trial, 82 patients known to be hepatitis B e antigen and hepatitis B virus DNA positive for at least 1 year, with elevated serum alanine aminotransferase levels and chronic liver lesions on biopsy, were randomized to receive either recombinant interferon alfa-2a at a dose of 4.5 million units thrice weekly for 4 months or no treatment. At the end of therapy, viral DNA clearance and aminotransferase normalization were significantly (p less than 0.05) more frequent in treated patients than in controls. After 16 months' follow up, the difference was still significant for hepatitis B e antigen clearance and transaminase normalization. Hepatitis B virus DNA reactivation was obse…
Application of headspace solid phase dynamic extraction gas chromatography/mass spectrometry (HS-SPDE-GC/MS) for biomonitoring of n-heptane and its m…
2011
Abstract Solid phase dynamic extraction (SPDE) is an innovative sample preparation and enrichment technique in connection with gas chromatography (GC). Using SPDE, we developed a method for simultaneous determination of n-heptane and its mono-oxygenated metabolites heptane-4-one, 3-one, 2-one, 4-ol, 3-ol, 2-ol, and 1-ol in blood. After adjustment of various extraction and desorption parameters, method validation resulted in limits of detection (LOD) between 0.006 (heptane-4-one) and 0.021 mg/L (heptane-1-ol). Intra-assay coefficients of variation ranged between 4.8% and 20.8% while relative recovery ranged between 100% and 117% (spiked concentration 0.128 mg/L, n = 8). The method was appli…
Testing an emotion regulation model of physical activity in adolescents with anorexia nervosa: A pilot ecological momentary assessment.
2019
Objective Adolescents with anorexia nervosa (AN) often show increased levels of exercise and physical activity. Psychological models suggest that physical activity in AN might attenuate momentary negative affect. However, this has not been directly tested in adolescents with AN, and it remains unclear whether this is a distinct mechanism of physical activity in AN compared with healthy controls (HCs). Method In a 1-day ecological momentary assessment, 32 adolescent inpatients with AN and 30 HCs responded to hourly questions on momentary affect while wearing an actigraph to objectively assess physical activity. Results Linear mixed models identified that adolescents with AN experienced more …
The relationship between central corneal thickness and Goldmann applanation tonometry
2003
The aim of this study was to investigate the relationship between Goldmann applanation tonometry and central corneal thickness in a large sample of healthy eyes.Five hundred eyes of 500 subjects (253 women, 50.6 per cent and 247 men, 49.4 per cent) were analysed in a prospective healthy population study. Mean age of the sample was 31 +/- 8 years. Goldmann applanation tonometry was carried out by one physician. Tonometric values were the mean of three consecutive readings. Subsequently, another physician carried out ultrasonic pachymetry with the DGH 2000 AP ultrasonic pachymeter (DGH Technology Inc, San Diego, USA). Ten measurements were made at the centre of the cornea of each eye. The low…
Long-term follow-up of endurance and safety outcomes during enzyme replacement therapy for mucopolysaccharidosis VI: Final results of three clinical …
2008
Abstract The objective of this study was to evaluate the long-term clinical benefits and safety of recombinant human arylsulfatase B (rhASB) treatment of mucopolysaccharidosis type VI (MPS VI: Maroteaux-Lamy syndrome), a lysosomal storage disease. Fifty-six patients derived from 3 clinical studies were followed in open-label extension studies for a total period of 97–260 Weeks. All patients received weekly infusions of rhASB at 1mg/kg. Efficacy was evaluated by (1) distance walked in a 12-minute walk test (12MWT) or 6-minute walk test (6MWT), (2) stairs climbed in the 3-minute stair climb (3MSC), and (3) reduction in urinary glycosaminoglycans (GAG). Safety was evaluated by compliance, adve…
