Genetic Factors and Susceptibility to Falls in Older Women
2006
OBJECTIVES: To determine whether genetic influences account for individual differences in susceptibility to falls in older women. DESIGN: Prospective twin cohort study. SETTING: Research laboratory and residential environment. PARTICIPANTS: Ninety-nine monozygotic (MZ) and 114 dizygotic (DZ) female twin pairs aged 63 to 76 from the Finnish Twin Cohort study. MEASUREMENTS: The participants recorded their falls on a calendar for an average+/-standard deviation of 344+/-41 days. Reported falls were verified via telephone interview, and circumstances, causes, and consequences of the fall were asked about. RESULTS: The total number of falls was 434, of which 188 were injurious; 91 participants h…
Alimentación y salud en la Valencia medieval. Teorías y prácticas
2013
The aim of this article is to provide an initial survey about the relationship between food habits and health in a Mediterranean city during the Late Middle Ages, by comparing medical treatises, gastronomic recipes and the archival sources that tell us about the actual expenses in food. Through this comparison, and by using accounting records of aristocratic houses, merchant enterprises, convents and hospitals, we can observe the dietary guidelines that were applied, and their concordance with the galenic principles of University medicine. Moreover, we attempt to assess what were the key factors in the evolution of these theories’ guidelines, and how they were probably rather a way to appro…
HPV group- and type-specific concordance in HPV infected sexual couples.
2007
The concordance of human papillomavirus (HPV) groups and types was evaluated in 45 sexual couples with both partners HPV infected, by analyzing cervical samples from women and three genital sites (penile brushing, urethral brushing, and semen) from men. When grouping HPV types, no significant HPV group sharing was found between partners, either considering samples from any male site (concordance: 55.5%; P = 0.11) or from each site (concordance by penile brushing, 37.8%; urethral brushing, 24.5%; semen, 22.3%; P > 0.05). Examining individual HPV types, using samples from any male site, concordance was found in 29 (64.4%; P = 0.036) couples; significant concordance was evident for 16 HPV geno…
Deep semantic lung segmentation for tracking potential pulmonary perfusion biomarkers in chronic obstructive pulmonary disease (COPD): The multi‐ethn…
2019
Background Chronic obstructive pulmonary disease (COPD) is associated with high morbidity and mortality. Identification of imaging biomarkers for phenotyping is necessary for future treatment and therapy monitoring. However, translation of visual analytic pipelines into clinics or their use in large-scale studies is significantly slowed by time-consuming postprocessing steps. Purpose To implement an automated tool chain for regional quantification of pulmonary microvascular blood flow in order to reduce analysis time and user variability. Study type Prospective. Population In all, 90 MRI scans of 63 patients, of which 31 had a COPD with a mean Global Initiative for Chronic Obstructive Lung …
Graphic representation of data resulting from measurement comparison trials in cataract and refractive surgery.
2003
* BACKGROUND AND OBJECTIVES: The evaluation of new diagnostic measurement devices allows intraindividual comparison with an established standard method. However, reports in journal articles often omit the adequate incorporation of the intraindividual design into the graphic representation. * PATIENTS AND METHODS: This article illustrates the drawbacks and the possible erroneous conclusions caused by this misleading practice in terms of recent method comparison data resulting from axial length measurement in 220 consecutive patients by both applanation ultrasound and partial coherence interferometry. * RESULTS: Graphic representation of such method comparison data should be based on boxplots…
Comparison of a rapid immunochromatographic test with a chemiluminescence immunoassay for detection of anti-SARS-CoV-2 IgM and IgG
2020
Introduction: The 2019 Coronavirus disease (COVID-19) has been characterized as a pandemic, representing a serious global public health emergency. Serological tests have been proposed as reliable tools for detecting Coronavirus SARS-CoV-2 antibodies in infected patients, especially for surveillance or epidemiological purposes. The aim of this study is to evaluate the agreement between the IgM/IgG rapid assays, based on lateral flow immunochromatographic assay, and the fully automated 2019-nCoV IgM and IgG, based on chemiluminescence immunoassay. Materials and methods: SARS-CoV-2 antibodies were measured with the BIOSYNEX COVID-19 BSS IgM/IgG test (BIOSYNEX, Illkirch-Graffenstaden, France) a…
Influence of image reconstruction parameters on cardiovascular risk reclassification by Computed Tomography Coronary Artery Calcium Score
2018
Objective: To investigate the influence of different CT reconstruction parameters on coronary artery calcium scoring (CACS) values and reclassification of predicted cardiovascular (CV) risk. Methods: CACS was evaluated in 113 patients undergoing ECG-gated 64-slice CT. Reference CACS protocol included standard kernel filter (B35f) with slice thickness/increment of 3/1.5 mm, and field-of-view (FOV) of 150â180 mm. Influence of different image reconstruction algorithms (reconstructed slice thickness/increment 2.0/1.0â1.5/0.8â3.0/2.0â3.0/3.0 mm; slice kernel B30f-B45f; FOV 200â250 mm) on Agatston score was assessed by Bland-Altman plots and concordance correlation coefficient (CCC) ana…
The correlation of functional pain and psychological distress: a study in Italian school students.
2019
Abstract Background Functional Pain (not detectable organic cause) is often associated with psychological problems and, according to literature, it can lead to severe manifestations. The purpose of the study was to investigate the correlation between functional pain and psychological disagreement, in a series of school students. Methods An observational questionnaire-based study was performed. A questionnaire was given to a group of students of primary school; the following data were collected in the questionnaire: a) sex and age; b) functional pain; c) relation with relatives, teachers and schoolfellows: d) school failure. Statistical methods: P-value of concordance test and P-value of cor…
Mobile microscopy as a screening tool for oral cancer in India: A pilot study
2017
Oral cancer is the most common type of cancer among men in India and other countries in South Asia. Late diagnosis contributes significantly to this mortality, highlighting the need for effective and specific point-of-care diagnostic tools. The same regions with high prevalence of oral cancer have seen extensive growth in mobile phone infrastructure, which enables widespread access to telemedicine services. In this work, we describe the evaluation of an automated tablet-based mobile microscope as an adjunct for telemedicine-based oral cancer screening in India. Brush biopsy, a minimally invasive sampling technique was combined with a simplified staining protocol and a tablet-based mobile mi…
POPULATION STRUCTURE OF ANISAKIS SIMPLEX (NEMATODA) IN HARBOR PORPOISES PHOCOENA PHOCOENA OFF DENMARK
2004
The population structure and habitat selection of Anisakis simplex in 35 harbor porpoises off Denmark are described. The nematodes were collected from the stomach and duodenal ampulla and were categorized as third-stage larvae, fourth-stage larvae, subadults, and adults. The porpoises harbored 8,043 specimens of A. simplex. The proportion of adults and subadults increased with infrapopulation size. The number of development stages across infrapopulations covaried significantly (Kendall's test of concordance). Concordance was higher in hosts with the highest intensities than in those with low and medium intensities. All stages occurred mainly in the forestomach, but this trend was stronger f…
