Attrition and Use of Proxy Respondents and Auxiliary Information in the Sicilian Neuroepidemiologic Study
1994
Two-phase prevalence surveys with screening (phase 1) and examination (phase 2) are useful for some chronic diseases. Attrition, which may bias estimates, occurs in either phase because some eligible subjects die before contact, some refuse to cooperate, some are incapacitated, and some are unreachable. This investigation relates to a survey of neurologic diseases conducted in three municipalities of Sicily (prevalence date, November 1, 1987) and considers the attrition experienced and the use of proxy respondents in phase 1 and auxiliary information in phase 2 to offset, in part, this attrition. Regarding case finding, the salvage effort was more productive for decreased and incapacitated …
Ankylosing spondylitis in monozygotic twins: studies on immunological parameters
1999
OBJECTIVE—To examine immunological parameters that might explain disease discordance in monozygotic twin pairs with ankylosing spondylitis (AS). METHODS—11 monozygotic twin pairs (nine with AS, two with undifferentiated spondyloarthropathy) were investigated. The peripheral T cell receptor Vβ repertoire was investigated using FACS analysis and 14 different Vβ antibodies. In addition serum samples were tested for antibodies to Klebsiella pneumoniae, Streptococcus pyogenes, Candida albicans, Proteus mirabilis, and Escherichia coli. Peripheral blood lymphocyte reactivity against a number of bacteria was investigated by interferon γ ELISPOT assays. RESULTS—Twins suffering from AS showed cellula…
Depression in the community: a comparison of treated and non-treated cases in two non-referred samples.
1992
Family studies in non-patient samples may help to clarify whether or not treatment-seeking behaviour is substantially determined by clinical features of depression. Life-time risks of depression were investigated by structured clinical interviews (SADS-LA) in both a high-risk sample of depressed patients' first-degree relatives and an unscreened control sample of the general population: 34.6% of the high-risk sample versus 23.1% of controls were cases of depression, with a female preponderance in both groups. The rates of treated depression were 17.0% versus 8.5%. Female sex, greater age, higher severity of episodes, manic or hypomanic episodes recurrent course, and introverted and anancast…
Interleukin-22 and interleukin-22-producing NKp44+ natural killer cells in subclinical gut inflammation in ankylosing spondylitis
2012
Objective The intestinal inflammation observed in patients with ankylosing spondylitis (AS) is characterized by an overexpression of interleukin-23 (IL-23). IL-23 is known to regulate IL-22 production through lamina propria NKp44+ natural killer (NK) cells, which are thought to be involved in protective mucosal mechanisms. This study was undertaken to evaluate the frequency of NKp44+ NK cells and the expression of IL-22 in the ileum of AS patients. Methods Tissue NKp44+ NK cells, NKp46+ NK cells, and IL-22–producing cells were analyzed by flow cytometry. Quantitative gene expression analysis of IL-22, IL-23, IL-17, STAT-3, and mucin 1 (MUC-1) was performed by reverse transcriptase–polymeras…
Association between nutritional values of hays fed to horses and sensory properties as perceived by human sight, touch and smell
2019
International audience; Although hay is the foundation of most equine diets, horse owners rarely ask for biochemical analysis and the routine practice is to choose hay based on its 'perceived' nutritional value. The present study aimed at exploring the relationship between sensory properties as perceived by sight, touch and smell, and the nutritional value of hay measured by biochemical analysis using a 'free sorting task' method. Fifty-four non-expert participants were asked individually to: (1) observe 21 hays samples, (2) group together hays that they perceived as similar for each of the three modalities (hay appearance, odour or texture) and (3) characterize each formed group with a max…
T2 Mapping of the Sacroiliac Joints in Patients with Axial Spondyloarthritis
2020
Purpose: To test whether T2 mapping of the sacro-iliac joints (SIJs) might help identifying patients with spondyloarthritis. Method: This study included 20 biologic-naive patients with axial spondyloarthritis (10 females; mean age: 38 ± 9years; range, 19–47) and 27 controls (16 males; mean age = 39 ± 13years; range = 28–71) who prospectively underwent SIJs MRI at 1.5 T, including a multislice multiecho spin-echo sequence. Standard MRIs were reviewed to assess the SIJs according to the Assessment of SpondyloArthritis International Society (ASAS) criteria and SPondyloArthritis Research Consortium of Canada (SPARCC) MRI index. T2 maps obtained from multiecho sequences were used to draw regions…
The concept of a surrogate is ill adapted to intensive care: Criteria for recognizing a reference person
2016
IF 2.445; International audience; Purpose: In the intensive care unit (ICU), caregivers may find it difficult to identify a suitable person in the patient's entourage to serve as a reference when there is no official surrogate.Methods: We developed a 12-item questionnaire to identify factors potentially important for caregivers when identifying a reference person. Each criterion was evaluated as regards its importance for the role of reference. Responses were on a scale of 0 (not important) to 10 (extremely important). We recorded respondent's age, job title, and number of years' ICU experience. The questionnaire was distributed to all health care professionals in 2 French ICUs.Results: Amo…
The dimensions of mobilities: The spatial relationships between corporeal and digital mobilities
2013
Abstract The aim of this article is to study how the corporeal and digital mobilities are spatially organised in relation to each other in everyday life. The dimensions of mobilities are modelled by using survey data (N = 612) collected from Finland in 2011, Multiple Correspondence Analysis (MCA) and Multiple Regression Analysis (MRA). The results show that the combined use of corporeal and digital means of mobility affect the spatial organisation of mobilities only little. The results indicate that young people and students are more likely to benefit from their mobility in networking activities as they are equipped with a larger variety of mobility means than older people and pensioners. L…
Exploring the relationship between demographic and disease-related variables and perceived effect of health status on sexual activity in patients wit…
2017
To explore the relationship between demographic and disease-related variables and the perceived effect of health status on sexual activity in patients with axial spondyloarthritis (ax-SpA).The study assessed 379 ax-SpA patients consecutively recruited from two rheumatology outpatient clinics. Data collection included information on demographics, markers and measures of ax-SpA disease, treatment, comorbidity, and health-related quality of life (HRQoL) using the Short Form-36. The perceived effect of health status on sexual activity was assessed using question 15 in the HRQoL instrument 15D.The mean age of the patients was 45.6 years, 66.5% were men, 87.3% were human leucocyte antigen-B27 pos…
Prevalence of cervical spondylotic radiculopathy: A door-to-door survey in a Sicilian municipality
1996
Introduction - Because of the limited information on cervical spondylotic radiculopathy, we conducted a door-to-door two-phase survey in a Sicilian municipality. Material and methods - We first screened for cervical spondylotic radiculopathy among the inhabitants of the municipality : (N= 7653, as of the prevalence day, November 1, 1987). Study neurologists then investigated those subjects suspected to have had a cervical spondylotic radiculopathy. Diagnoses were based on specified criteria. Results - We found 27 subjects affected by CSR (17 definite, 10 possible). Prevalence (cases per 1000 population) was 3.5 in the total population ; it increased to a peak at age 50-59 years and decrease…
