Analysis of the sleep period and the amount of habitual snoring in individuals with sleep bruxism
2019
Background The literature does not report any association between habitual snoring and sleep bruxism, but these situations can be a reason for frequent complaints of individuals, impairing the quality of life. This study was performed to investigate the sleep period and amount of habitual snoring in individuals with sleep bruxism observing expiratory, inspiratory, and mixed snoring. Material and Methods A total of 90 individuals were screened and divided into the following groups: with sleep bruxism (n=45) and those without sleep bruxism (n=45). Single night sleep polysomnography was performed to diagnose sleep bruxism, quantify habitual snoring and sleep period. The results were tabulated …
Procedural Memory Following Moderate-Severe Traumatic Brain Injury: Group Performance and Individual Differences on the Rotary Pursuit Task
2019
The impact of traumatic brain injury (TBI) on procedural memory has received significantly less attention than declarative memory. Although to date studies on procedural memory have yielded mixed findings, many rehabilitation protocols (e.g., errorless learning) rely on the procedural memory system, and assume that it is relatively intact. The aim of the current study was to determine whether individuals with TBI are impaired on a task of procedural memory as a group, and to examine the presence of individual differences in performance. We administered to a sample of 36 individuals with moderate-severe TBI and 40 healthy comparisons (HCs) the rotary pursuit task, and then examined their rat…
Imaging of hepatocellular carcinoma: a pilot international survey
2020
Purpose To perform an international survey on current practices in imaging-based surveillance, diagnosis, staging, and assessment of treatment response for HCC. Materials and methods Three themes were covered in this international survey: demographics of respondents and liver imaging expertise; imaging practices for screening, surveillance, diagnosis, staging, and assessment of treatment response for HCC; and diagnostic imaging systems used. Descriptive summaries were created. Results Of 151 respondents, 22.5% were from Asia, 6.0% from Europe, 19.9% from North America, 26.5% from South America, and 25.2% from Australasia; 57.0% respondents worked in academic and 34.4% in private or mixed se…
Three single loops enhance the biomechanical behavior of the transtibial pull-out technique for posterior meniscal root repair
2017
Purpose: To investigate the effect of applying an additional suture to enhance the biomechanical behavior of the suture–meniscus construct used during the transtibial pull- out repair technique. Methods: A total of 20 fresh-frozen porcine tibiae with intact medial menisci were used. In one half of all speci- mens (N = 10), two non-absorbable sutures were passed directly over the meniscal root from the tibia side of the meniscus to the femoral side (2SS). In other ten specimens, three sutures were passed over the meniscal root (3SS). All specimens were subjected to cyclic loading followed by load-to-failure testing. Displacement of the construct was recorded at 100, 500, and 1000 cycles. Fur…
Randomized Prospective Study in Patients With Complex Regional Pain Syndrome of the Upper Limb With High-Frequency Spinal Cord Stimulation (10-kHz) a…
2021
Objective The objective of this prospective randomized study of cases and controls was to evaluate the efficacy of treatment with low-frequency spinal cord stimulation (LF-SCS) and 10 kHz spinal cord stimulation (10-kHz SCS) in patients diagnosed with complex regional pain syndrome type I (CRPS) with upper limb involvement. Materials and methods Fifty patients were randomized to receive conventional treatment or SCS with a commercially available low-frequency or 10-kHz system. Patients were assessed at 1, 3, 6, and 12 months. The primary endpoint was at 12-months post permanent implantation of the SCS devices. Outcome measures assessed included: Numerical Rating Scale (NRS), 12-Item Short-F…
Reading ability with 3 multifocal intraocular lens models.
2006
Purpose To prospectively evaluate reading performance with of 3 types of multifocal intraocular lenses (IOLs) under different lighting conditions based on reading acuity and reading speed tests. Setting Augenklinik, Bad Hersfeld, Germany. Methods This randomized study comprised 60 cataract patients (120 eyes) randomly assigned to receive an SA40N IOL (AMO) (Group 1, 20 patients), Tecnis ZM001 IOL (AMO) (Group 2, 20 patients), or AcrySof ReSTOR SA60D3 IOL (Alcon) (Group 3, 20 patients). Pupil size and reading ability at near (visual acuity, reading speed) without correction, with best distance correction, and with best near correction were assessed 6 weeks postoperatively under low-light con…
Efficacy and safety of ranibizumab with or without panretinal laser photocoagulation versus laser photocoagulation alone in proliferative diabetic re…
2019
Purpose Panretinal photocoagulation (PRP) is the current standard of care in proliferative diabetic retinopathy (PDR). However, treatment with anti-vascular endothelial growth factor agents might offer better patient outcomes with fewer side-effects. The PRIDE study aimed to assess the efficacy and safety of ranibizumab with or without PRP compared with PRP alone in patients with PDR. Methods A total of 106 PDR patients without diabetic macular oedema were randomized to receive ranibizumab 0.5 mg monotherapy (n = 35), PRP (n = 35) or combined ranibizumab 0.5 mg/PRP (n = 36). The primary objective of this 12-month, multicentre, phase II study was to investigate the change in area of retinal …
Modified cryopreservation and xenotransplantation of human parathyroid tissue.
1999
Introduction: A modified cryopreservation technique for human parathyroid tissue was compared with the standard method using a programmed freezer. Methods: Total parathyroidectomy was performed in three groups of 6-week-old Rowett nude rats. Group I (control) underwent no transplantation of parathyroid tissue (n=9). After 10 days, the rats of groups II (n=15) and III (n=15) underwent xenotransplantation of 20 mg cryopreserved human parathyroid tissue, which had been stored in liquid nitrogen at –196°C for 1–22 months prior to xenotransplantation. The parathyroid tissue was derived from 15 parathyroidectomized patients with renal hyperparathyroidism. Two tissue samples were obtained from eve…
Gender and Age Group Differences in Stereotypes about Mental Health Care Providers
2013
Mental health care providers play a significant role in the prevention of mental health problems and promotion of well-being. The aim of the study was to explore gender and age group differences in stereotypes about helping professionals in the mental health care field. The data were derived from 338 Latvian-speaking adults aged 18 to 87. They rated stereotypic characteristics of five typical helping professionals (a family doctor, a psychologist, a psychiatrist, a clergyman, and an astrologer) on a seven-point Likert-type scale. The stereotype content model was used to measure warmth and competence stereotypes (Fiske, Xu, Cuddy, & Glick, 1999). Gender differences show that women rate a typ…
