Brain density in depression: methodological and psychopathological aspects
1988
The relationship between brain density, measured by computerized tomography (CT), and severity of depression was investigated in 44 patients with a major depressive episode according to DSM-III. In order to limit methodological problems, correlations between both the Brief Psychiatric Rating Scale (BPRS) and the Bech-Rafaelsen Melancholia Scale (BRMS) with density values were controlled for age, different ventricle measurements, brain size, and density and size of the skull. The BRMS score correlated inversely with density of the right thalamus, the right head of the caudate, and with parietal grey matter and occipital regions of both hemispheres. Similar, but nonsignificant results, were o…
Sibship size, birth order and psychotic experiences: Evidence from 43 low- and middle-income countries.
2018
Background: Sibship size and birth order may be contributing factors to the multifactorial etiology of psychosis. Specifically, several studies have shown that sibship size and birth order are associated with schizophrenia. However, there are no studies on their association with psychotic experiences (PE). Methods: Cross-sectional, community-based data from 43 low- and middle-income countries which participated in the World Health Survey were analyzed. The Composite International Diagnostic Interview was used to identify four types of past 12-month PE. The association of sibship size and birth order with PE was assessed with multivariable logistic regression. Results: The final sample consi…
Early age of onset, brain morphological changes and non-consistent motor asymmetry in schizophrenic patients.
1999
Previous data suggest abnormalities in the consistence of motor dominance in schizophrenia (e.g. mixed-handedness, poor correlation between hand, eye and foot preferences and an increase of hand-eye crossed dominance). The aim of this work is to examine the clinical significance of hand-eye and hand-foot crossed dominance in a sample of 61 right-handed schizophrenic patients. The application of multivariate analysis revealed that 23 right-handed and non-right-eyed patients (crossed hand-eye dominant group) had a significant earlier clinical onset and smaller brain size, global and frontal area, than 38 right-handed and right-eyed schizophrenics (consistent hand-eye dominance group). These f…
Peripapillary Choroidal Thickness and Choroidal Area in Glaucoma, Ocular Hypertension and Healthy Subjects by SD-OCT.
2015
Background: The exact pathogenesis of open angle glaucoma and ocular hypertension remains unclear. Hemodynamic influences are discussed as potential risk factors and the choroid may play an important role in the pathogenesis of open angle glaucoma or ocular hypertension. The current study investigates peripapillary choroidal thickness and choroidal area in patients with open angle glaucoma, subjects with ocular hypertension and healthy subjects using spectral-domain OCT. It furthermore assesses the association between peripapillary choroidal thickness and age, central corneal thickness, refractive error and intraocular pressure. Patients and Methods: Prospectively recorded data of 213 eyes …
Endothelial study of iris-claw phakic lens: four year follow-up.
1998
Abstract Purpose: To study quantitative and morphometric endothelial changes in phakic eyes implanted with the Worst iris-claw lens to correct high myopia. Setting: Department of Ophthalmology, University Hospital “La Fe”, Valencia, Spain. Material and Methods: This retrospective study involved 111 phakic eyes (73 patients) implanted with the Worst iris-claw lens. Noncontact specular microscopy and computer-assisted analysis was performed preoperatively and 6 months and 1, 2, 3, and 4 years postoperatively. Results: The mean cell loss was 3.85% at 6 months, 6.59% at 1 year, 9.22% at 2 years, 11.68% at 3 years, and 13.42% at 4 years. At 2 years, the hexagonality and coefficient variation in …
Early life body mass trajectories and mortality in older age: Findings from the Helsinki Birth Cohort Study
2014
Overweight and obesity in childhood have been linked to an increased risk of adult mortality, but evidence is still scarce.We identified trajectories of body mass index (BMI) development in early life and investigated their mortality risk. Data come from the Helsinki Birth Cohort Study, in which 4943 individuals, born 1934-1944, had serial measures of weight and height from birth to 11 years extracted from health care records, weight and height data in adulthood, and register-based mortality data for 2000-2010.Three early BMI trajectories (increasing, average, and average-to-low for men and increasing, average, and low-to-high BMI for women) were identified. Women with an increasing or low-…
The impact of mastication, salivation and food bolus formation on salt release during bread consumption
2014
Health authorities recommend higher fibre and lower salt content in bread products. However, these basic ingredients of bread composition are multifunctional, and important changes in their content influence the texture, flavour and acceptability of the product. This study was designed to investigate the link between oral processing, bolus formation and sodium release during the consumption of four different breads that varied in composition and structure. Chewing behaviour was determined by surface electromyography, and salivation was quantified from the water content of the boluses collected. The kinetics of bread degradation during food bolus formation was characterised by measuring the …
Study of lip hydration with application of photoprotective lipstick : influence of skin phototype, size of lips, age, sex and smoking habits
2009
Objectives: To study lip hydration levels when applying a lipstick sunscreen for 3 months and to evaluate the influence of size of lips, age, sex, smoking and skin phototype. Study design: The study group was formed by 140 volunteer subjects, one group consisting of 70 patients applying a commercial lipstick sunscreen three times a day and the other group of 70 controls in which no product was applied. The age range was 20-86 years. The influence in lip hydration levels of age, sex, phototype, size of the lips and smoking habits was studied using a Corneometer 825® (Courage and Khazaka Electronic GmbH, Cologne, Germany). Results: An increase in lip hydration was found between the basal (53.…
Association of obesity and diabetes with thyroid nodules
2017
Aim: There are conflicting data concerning the possibility that obesity and diabetes raise the risk of thyroid nodules. The incidence of thyroid nodules is increasing, as is that of obesity and diabetes; therefore, understanding whether these metabolic and nutritional disorders influence nodular thyroid disease is important for organizing prevention strategies. This study investigated the association between thyroid nodules, obesity, diabetes, and dietary habits. Materials and methods: A cohort of randomly selected adults (455 males, 746 females; age: 18â90 years) living in Palermo (Italy), a mild iodine deficiency area, was cross-sectionally investigated. Participants underwent high-reso…
The big picture: effects of surround on immersion and size perception.
2014
Despite the fear of the entertainment industry that illegal downloads of films might ruin their business, going to the movies continues to be a popular leisure activity. One reason why people prefer to watch movies in cinemas may be the surround of the movie screen or its physically huge size. To disentangle the factors that might contribute to the size impression, we tested several measures of subjective size and immersion in different viewing environments. For this purpose we built a model cinema that provided visual angle information comparable with that of a real cinema. Subjects watched identical movie clips in a real cinema, a model cinema, and on a display monitor in isolation. Wher…
