Haemorheological components in the pre-geriatric and geriatric age range in a randomly selected Western Sicily population sample (Casteldaccia study)
1993
{Received 24.8.1992; accepted 7.12.1992} On a randomly selected western Sicily population sample (Casteldac cia Study: 600 subjects; 300 males and 300 females) of an age range from 40 to 79 years, were determined: Haematocrit (Htc) , blood vi scosity, plasma viscosity, filterability of whole blood and fibrinogen. Par ticipation was 97%, being 582 subjects (M = 287, F = 295). All the parameters measured showed a progressive increase with age and si gnificant differences were found between male and female subjects: Htc and blood viscosity were higher in male subjects (p < 0.01), while plasma viscosity, whole blood filterability and fibrinogen were higher in female subjects (p < 0.05). In …
The latent nature of prolonged grief - A taxometric analysis: Results from a representative population sample
2017
Individuals suffering from prolonged grief disorder (PGD) show severe grief reactions after the death of a significant other, even beyond a period of grieving that is within a person's cultural and religious context. In addition to this core element, PGD can manifest in various ways. Symptoms may include persistent preoccupation, intense emotional pain, or impairment in important life domains. The symptoms, furthermore, have to be of culturally or religiously inappropriate extent or severity, taking into account different norms of grieving. PGD is discussed as a distinct diagnostic category in the revision of the International Classification of Diseases (ICD-11). Nosology of PGD has been hi…
Y-chromosomal STR haplotypes in Sicily
2006
Eight Y-chromosomal short tandem repeats (STRs)-DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393 and DYS385 - were typed in a population sample (n = 255) of unrelated Sicilian males from nine different towns on the main island and from the island of Pantelleria.

Accuracy of two plasma antibody tests and faecal antigen test for non-invasive detection of H. pylori in middle-aged Caucasian general population sam…
2018
The aim of the study was to assess the accuracy of two plasma Helicobacter pylori (H. pylori) antibody test-systems and a stool antigen test (SAT) system in a general population sample in Latvia.Blood and faecal samples were analysed in healthy individuals (40-64 years), referred for upper gastrointestinal endoscopy according to pilot study protocol within a population-based study investigating gastric cancer prevention strategies (GISTAR pilot study). Antibodies to H. pylori were assessed in plasma by latex-agglutination test and enzyme-linked immunosorbent assay (ELISA). H. pylori antigen in faecal samples was detected by a monoclonal enzyme immunoassay-based SAT. Histological assessment …
Disability, Health-Related Quality of Life and Mortality in Lumbar Spine Fusion Patients : A 5-Year Follow-Up and Comparison With a Population Sample
2022
Study Design: Prospective follow-up study. Objectives: We aimed to assess the effect of lumbar spine fusion (LSF) on disability, health-related quality of life and mortality in a 5-year follow-up, and to compare these results with the general population. Methods: 523 consecutive LSF operations were included in a prospective follow-up. Disability was assessed by the Oswestry Disability Index (ODI), and HRQoL by the 36-item Short Form (SF-36) questionnaire using the physical and mental summary scores (PCS and MCS). The patients were compared with an age-, sex-, and residential area matched general population cohort. Results: The preoperative ODI in the patients was 46 (SD 16), and the change …
Sensitivity of the central visual field in 70- to 81-year-old male athletes and in a population sample.
1994
The sensitivity of the central visual field (0°–30°) was studied using an automatic Octopus 500E perimeter in elderly male athletes and in a population sample of men of corresponding age. The athletes (N=96) were endurance and power athletes, who were still active in competitive sports with training histories spanning tens of years. The athletes’ results were compared with those of a sample of men of the same age (70–81 years, N=41) randomly selected from the local population register. The sensitivity values of the athletes, and the endurance athletes in particular, were significantly better than those of the controls, with differences varying from 1 to 2.5 dB in the different areas of the …
Development of a sensory tool to assess overall liking for the fatty, salty and sweet sensations
2016
Abstract Understanding the origin of the overconsumption of too high levels of sucrose, sodium chloride and lipids in foods raises the question of the influence of the hedonics for these sensations. To better understand this relationship, a sensory tool that enables measurement of liking towards sweet, salty or fatty sensations is required. This liking towards a sensation has to be understood as an overall attractiveness of the sensation. Instruments already existing were unsatisfactory as including a limited number of foods not representative of the overall sensation. A set of hedonic tests, named PrefSens, was developed to measure an overall liking for fatty, salty or sweet sensations. Ea…
Disability and health-related quality of life in patients undergoing spinal fusion: a comparison with a general population sample
2013
Background. The aim of the present study was to compare one-year-follow-up data on disability and health-related quality of life (HRQoL) between spinal fusion patients and age- and sex-matched general population. Methods. The data on fusion patients were collected prospectively using a spinal fusion data base in two Finnish hospitals. A general population sample matched for age, sex and residential area was drawn from the Finnish Population Register. All participants completed a questionnaire and the main outcome measures were the Oswestry Disability Index (ODI) and the Short Form-36 questionnaire (SF-36). Results. Altogether 252 (69% females) fusion patients and 682 (67% females) populatio…
Prevalence of nocturnal asthma in a general population sample: determinants and effect of aging.
2000
Nocturnal asthma (NA) is important because of clinical and prognostic implications. Previous data on prevalence may be overestimated, because they are derived from selected series. Observations on monitoring of peak expiratory flow in elderly asthmatics suggested that prevalence of NA may increase with age. This study was designed to estimate the prevalence of NA-related symptoms in a sample drawn from a general population and evaluate the role of aging. Subjects (1,100, mean age 41.9, SD 22.8 years) were randomly selected from the lists of seven general practitioners. A questionnaire on nighttime and morning NA-associated symptoms was used and frequency of occurrence was rated as never, so…
Underdiagnosis Of Asthma And Associated Risk Factors In Italian General Population Samples
2017
Background: asthma underdiagnosis was reported in many recent studies, in particular in older subjects. Aim: to assess the risk factors associated with asthma underdiagnosis in two Italian general population samples. Methods: two general population samples living in Pisa (Central Italy, urban/suburban area) and Po Delta (North Italy, rural area) participated in some cross-sectional studies between 1980 and 2011. Through a questionnaire on health status and risk factors, Pisa sample was investigated in 1985-1988, 1991-1993 and 2009-2011; Po Delta sample was investigated in 1980-1982 and 1988-1991. Individuals reporting asthma symptoms or diagnosis in the previous studies were recently enroll…
