Peripheral corneal thickness and associated factors - results from the population-based German Gutenberg Health Study.
2021
PURPOSE Changes in peripheral corneal thickness are described in various corneal diseases such as corneal ectasia. However, few data exist describing the increase in corneal thickness from central to peripheral and reporting the normal distribution of corneal thickness in rings around the corneal centre. The aim of this study was to report these cornea characteristics and investigate associated factors in a population-based setting. METHODS The Gutenberg Health Study is a prospective, population-based study examining participants in a 5-year follow-up (age range 40-80 years) using Scheimpflug imaging. Corneal thickness was assessed in each participant at the apex, as well as in the corneal …
A retrospective 11-year study on lip lesions attended at an oral diagnostic service
2019
Background The objective of this study was to describe the upper and lower lip lesion occurrence in an oral diagnostic service. Material and Methods Retrospective descriptive sectional study was performed. Clinical records were obtained from the archives of an Oral Diagnostic Service referral center between 2006 and 2016. Data such as gender, age, anatomical location, and diagnosis were collected and categorized. The collected data were submitted to a descriptive analysis and Pearson's chi-square test (p ≤ 0.05). Results A total of 587 patient records of lip lesions were analyzed. Most lesions were diagnosed in female (52.1%) and adults (56.9%) patients in the lower lip (76.2%). Among all l…
Diagnostic Capability of a New Objective Method to Assess Meibomian Gland Visibility
2021
SIGNIFICANCE The diagnosis of dry eye disease and meibomian gland dysfunction (MGD) is challenging. Measuring meibomian gland visibility may provide an additional objective method to diagnose MGD. PURPOSE This study aimed to evaluate the ability of new metrics to better diagnose MGD, based on measuring meibomian gland visibility. METHODS One hundred twelve healthy volunteers (age, 48.3 ± 27.5 years) were enrolled in this study. Ocular surface parameters were measured using the Oculus Keratograph 5M (Oculus GmbH, Wetzlar). Subjects were classified according to the presence or absence of MGD. New metrics based on the visibility of the meibomian glands were calculated and later compared betwee…
Effects of strength vs. endurance training and their combination on physical performance characteristics in female horseback riders
2020
BACKGROUND: The purpose of this study was to investigate effects of strength (S), endurance (E) and concurrent strength and endurance (SE) training on neuromuscular and cardiorespiratory characteristics during the 12-week volume-equated protocols in female horseback riders. METHODS: Subjects (N=44) (29.4±8.9 yrs) were assigned to S (n=11), E (n=11), SE (n=13) and control (C) (n=9) groups. Training consisted of progressive S, E or SE training 3x/week and riding exercise 4-6x/week. The measurements included maximal isometric bilateral leg press force (MVCLP) and EMG of VL and BF muscles, rapid isometric force production (0-500ms), maximal force of trunk extensor/flexors (MVCE/MVCF), countermo…
Hyaluronic acid and platelet-rich plasma, a new therapeutic alternative for scleroderma patients: a prospective open-label study
2019
Abstract Background Systemic sclerosis is a systemic connective tissue disease characterized by endothelium damage, fibrosis, and subsequent atrophy of the skin. Perioral fibrosis produces a characteristic microstomia together with microcheilia, both of which cause severe difficulties and affects patients’ daily life, such as eating and oral hygiene. Since there are no effective and specific therapies, we have aimed at evaluating the response to filler injections of hyaluronic acid together with platelet-rich plasma. Methods Ten female patients aged between 18 and 70 were included in this study. Each patient was treated with three filler injections of hyaluronic acid and platelet-rich plasm…
Self-Reported Restrictive Eating, Eating Disorders, Menstrual Dysfunction, and Injuries in Athletes Competing at Different Levels and Sports
2021
The purpose of this study was to investigate the prevalence of self-reported restrictive eating, current or past eating disorder, and menstrual dysfunction and their relationships with injuries. Furthermore, we aimed to compare these prevalences and associations between younger (aged 15–24) and older (aged 25–45) athletes, between elite and non-elite athletes, and between athletes competing in lean and non-lean sports. Data were collected using a web-based questionnaire. Participants were 846 female athletes representing 67 different sports. Results showed that 25%, 18%, and 32% of the athletes reported restrictive eating, eating disorders, and menstrual dysfunction, respectively. Higher ra…
Mitochondrial transcriptional study of the effect of aflatoxins, enniatins and carotenoids in vitro in a blood brain barrier model
2020
C. maxima (var. Delica), a variety of pumpkin, is well known for its high concentration on carotenoids, possessing dietary benefits and antioxidant properties. Aflatoxins and enniatins are common mycotoxins present in food and feed with an extended toxicity profile in humans and animals. Both types of substances reach a wide range of tissues and organs and have the capability to penetrate the blood brain barrier. Since carotenoids and mycotoxins have been reported to modify diverse mitochondrial processes individually, transcriptional in vitro studies on human epithelial cells ECV 304 were conducted to analyze the relative expression of 13 mitochondria related genes. ECV 304 cells were diff…
Gaussian Mixture Models and Model Selection for [18F] Fluorodeoxyglucose Positron Emission Tomography Classification in Alzheimer’s Disease
2015
We present a method to discover discriminative brain metabolism patterns in [18F] fluorodeoxyglucose positron emission tomography (PET) scans, facilitating the clinical diagnosis of Alzheimer's disease. In the work, the term "pattern" stands for a certain brain region that characterizes a target group of patients and can be used for a classification as well as interpretation purposes. Thus, it can be understood as a so-called "region of interest (ROI)". In the literature, an ROI is often found by a given brain atlas that defines a number of brain regions, which corresponds to an anatomical approach. The present work introduces a semi-data-driven approach that is based on learning the charac…
Quality of Life in Dementia: Impact of Cognition and Insight on Applicability of the SF-36
2011
Comparability of measures of quality of life in dementia and in other diagnostic groups, such as mild cognitive impairment, normal aging, or other diseases, is highly desirable. However, the impact of cognitive deficits and impaired insight on applicability and validity of generic instruments is sparsely studied.Sixty patients with dementia [38 women; age: mean (SD) = 78.7 (6.4) years; Mini-Mental State Examination (MMSE): mean (SD) = 20.2 (6.0)] recruited as part of the start-modem study, a multicenter care research study in Germany, completed the generic instrument SF-36 and the specific instrument Quality of Life-Alzheimer's Disease (QOL-AD).QOL-AD self-rating scores [mean (SD) = 32.8 (5…
