Biomechanical properties of oesophagus wall under loading
2003
In this investigation, firstly, the biomechanical properties of different parts of oesophagus were determined. Oesophagus stress and strain are the greatest in the cervical part for all age groups. The human oesophagus deforms unevenly, depending on the direction of load in relation to the organ's axis, it exhibits anisotropical behaviour. With the age the values of mechanical parameters of the oesophagus wall reduce, in particular beginning from 45 years of age, but the modulus of elasticity increases. Biomechanical properties of the oesophagus depend on the architecture of its structure. By loading the organ in the circumferential direction, microfibrilae rupture and deformation of the mu…
Repeatability assessment of biometric measurements with different refractive states and age using a swept-source biometer
2018
Background We aim to assess if refractive error or age may influence the repeatability of measurements using a swept-source biometer. Methods A total of 61 subjects were evaluated with IOLMaster 700 acquiring measurements of axial length (AL), central corneal thickness (CCT), white-to-white distance (WTW), anterior aqueous depth (AQD), lens thickness (LT), and keratometry (K) readings. Repeatability was evaluated classifying the sample according to the refractive state and age by the calculation of the within-subject standard deviation (Sw), coefficient of repeatability, and intraclass correlation coefficient. Results Very similar Sw was acquired among groups for AL, CCT, and WTW. Differenc…
Age Differences in Face Processing: The Role of Perceptual Degradation and Holistic Processing
2017
Abstract Objectives We simultaneously investigated the role of three hypotheses regarding age-related differences in face processing: perceptual degradation, impaired holistic processing, and an interaction between the two. Methods Young adults (YA) aged 20–33-year olds, middle-age adults (MA) aged 50–64-year olds, and older adults (OA) aged 65–82-year olds were tested on the context congruency paradigm, which allows measurement of face-specific holistic processing across the life span (Meinhardt-Injac, Persike & Meinhardt, 2014. Acta Psychologica, 151, 155–163). Perceptual degradation was examined by measuring performance with faces that were not filtered (FSF), with faces filtered to …
Age Identification: A Comparison between Finnish and North-American Cultures
1998
This study examined perceptions of age among Finnish males and females in three age groups; twenty-five to thirty-nine-year-olds ( n = 446), forty to fifty-four-year-olds ( n = 482) and fifty-five to sixty-four-year-olds ( n = 427). The age perceptions of the Finnish sample were further compared with those of a North-American sample with corresponding age groups ( n = 169, n = 187, n = 222) reported by Barak, Stern, and Gould (1988). Four age concepts used were chronological age, subjective age, ideal age, and disparity age. As expected on the basis of previous studies in age identification, no difference was found between Finnish males and females in terms of subjective age. Ideal age, ho…
Correlates of vibrotactile thresholds in men of different ages
1986
— As a part of a larger gerontological research project vibrotactile thresholds on the inner malleolus of the ankle were studied in 355 men aged 31–35, 51–55 and 71–75 years. The groups studied were random samples of men living in the town of Jyvaskyla in Finland in the year 1981. The thresholds were assessed at three frequencies: 50 Hz, 100 Hz and 250 Hz. The thresholds were associated with age at all frequencies, the means of the threshold values being significantly higher in the older age groups. Within the age groups the thresholds correlated positively with height. In addition, reaction and movement time, leg extension velocity, and postural sway were associated with the thresholds. Ne…
Postural Sway During Standing and Unexpected Disturbance of Balance in Random Samples of Men of Different Ages
1985
Postural sway behavior while standing and during and after an unexpected disturbance of balance was examined in men aged 31 to 35, 51 to 55, and 71 to 75 years. The groups studied were random samples of men living in the town of Jyväskylä in 1981. Postural sway while standing was more pronounced in the older age groups, whereas after a disturbance of balance postural sway was nearly the same in all age groups. The functioning of the postural control system was correlated with the vibratory threshold on the ankles, grip strength, as well as with aerobic and anaerobic capacity within the age groups. Further, in the youngest age group the functioning of the postural control system was poorer a…
Conflicting rationales: leader's experienced ethical challenges in community health care for older people.
2017
BACKGROUND Ethical challenges arise in all types of care, and leaders need to be aware of how to resolve these challenges. Healthcare systems tend to be organised around medical conditions, and the patient is often faced with a series of uncoordinated visits to multiple specialties. Ideally, care should be organised around the patient's needs. AIM The purpose of this article was to highlight some ethical challenges perceived by leaders with responsibility for management and service distribution, finance and ensuring quality of community health services for older people. METHOD This study had a qualitative design with a qualitative content analysis of one focus group with six leaders that me…
Balantidiasis in Aymara children from the northern Bolivian Altiplano.
1998
Balantidium coli infection was coprologically studied in 2,124 Aymara children 5-19 years of age from the schools of 22 communities of the northern Bolivian Altiplano over a five-year period. Infection with B. coli was found in 11 of the communities surveyed, with prevalences of 1.0-5.3% (overall prevalence=1.2%). The prevalences observed are some of the highest reported and did not differ significantly among the various age groups or between boys and girls. These prevalences, the apparent absence of symptoms or signs of illness due to this parasite in the schoolchildren surveyed at the time of stool sampling, and the consistency of stool samples of the infected students suggest that they a…
Perceptions and experiences of parenthood and maternal health care among Latin American women living in Spain: A qualitative study
2013
Objective: to explore the experiences and perceptions of parenthood and maternal health care among Latin American women living in Spain. Design: an exploratory qualitative research using focus groups and thematic analysis of the discussion. Setting and participants: three focus groups with 26 women from Bolivia and Ecuador and three focus groups with 24 midwives were performed in three towns in the Valencian Community receiving a large influx of immigrants. Findings: the women interpreted motherhood as the role through which they achieve fulfilment and assumed that they were the ones who could best take care of their children. They perceived that men usually make decisions about sex and pre…
Burden of disease assessment with summary measures of population health for the Region of Valencia, Spain: a population-based study
2011
Abstract Background and objective An important input to decision-making and health planning is a consistent and comparative description of the population health status. The purpose of this study was to describe the burden of disease in the Region of Valencia (Spain). Material and methods Disability-adjusted life years (DALYs) were calculated and divided into years of life lost (YLLs) and years lived with disability (YLDs). Using death registry data and Valencian population estimates in 2008, we calculated the number of deaths and YLLs. YLDs were based on age- and sex-specific data for countries of the EURO-A subregional level (which includes the Region of Valencia) from the Global Burden of…
