The present retrospective cohort study was conducted to compare sporting activity levels before and a minimum of 10 years after primary cementless total hip arthroplasty (THA). A consecutive series of 86 patients with a mean age at surgery of 52 years (range, 21-60 years) was evaluated 11 years after surgery (range, 10-12 years). Pre- and post-operative sporting activities were assessed at routine follow-up using the University of California, Los Angeles activity score and the Schulthess Clinic sports and activity questionnaire. Post-operative health-related quality of life was measured using the Short-Form 36 (SF-36) questionnaire and compared with age-matched reference populations from the SF-36 database. Eleven years after THA, 89% of preoperatively active patients had returned to sport. Comparing sports activity preoperatively (before the onset of symptoms) and 11 years after THA, no significant difference was found for the mean number of disciplines or session length. A significant decline in high-impact activities was observed, while participation in low-impact activities significantly increased. Health-related quality of life compared well against a healthy age-matched reference population and was significantly higher than in a reference group of patients with osteoarthritis. The majority of patients were able to maintain their physical activity level in the long term after primary cementless THA, compared with the activity level before the onset of restricting osteoarthritis symptoms. However, a change in disciplines toward low-impact activities was observed.
Background and purposeUncemented acetabular components in primary total hip arthroplasty (THA) are commonly used today, but few studies have evaluated their survival into the second decade in young and active patients. We report on a minimum 10-year follow-up of an uncemented press-fit acetabular component that is still in clinical use.MethodsWe examined the clinical and radiographic results of our first 121 consecutive cementless THAs using a cementless, grit-blasted, non-porous, titanium alloy press-fit cup (Allofit; Zimmer Inc., Warsaw, IN) without additional screw fixation in 116 patients. Mean age at surgery was 51 (21–60) years. Mean time of follow-up evaluation was 11 (10–12) years.ResultsAt final follow-up, 8 patients had died (8 hips), and 1 patient (1 hip) was lost to follow-up. 3 hips in 3 patients had undergone acetabular revision, 2 for deep infection and 1 for aseptic acetabular loosening. There were no impending revisions at the most recent follow-up. We did not detect periacetabular osteolysis or loosening on plain radiographs in those hips that were evaluated radiographically (n = 90; 83% of the hips available at a minimum of 10 years). Kaplan-Meier survival analysis using revision of the acetabular component for any reason (including isolated inlay revisions) as endpoint estimated the 11-year survival rate at 98% (95% CI: 92–99).InterpretationUncemented acetabular fixation using the Allofit press-fit cup without additional screws was excellent into early in the second decade in this young and active patient cohort. The rate of complications related to the liner and to osteolysis was low.
ZUSAMMENFASSUNGDie nicht alkoholische Fettleber gilt in Europa und den USA als die häufigste Ursache für chronische Lebererkrankungen. Experten gehen davon aus, dass in Europa bis zu 30 % der Bevölkerung davon betroffen sind. Zu viel Fett in der Leber führt dabei nicht nur zu einer chronischen Erkankung der Leber, es hat auch einen negativen Einfluss auf den Zuckerstoffwechsel und führt beispielsweise zur Entwicklung eines Typ-2-Diabetes. Aus diesem Grund rücken neue Möglichkeiten zur Therapie der Fettleber immer mehr in den Fokus. Dabei werden sowohl Ernährungsumstellungen als auch medikamentöse Ansätze berücksichtigt. Um den Zusammenhang zwischen Leber und Typ-2-Diabetes noch zielgerichteter zu untersuchen, baut das Deutsche Zentrum für Diabetesforschung einen Forschungsschwerpunkt zum Thema Fettleber auf.
To improve employee performance, every organization needs to pay attention to the job satisfaction of its employees. One of the factors that can affect employee job satisfaction is the environmental conditions in the place where he works, both physical and non-physical. This study aims to analyze the effect of the physical work environment on job satisfaction of PD Sahang Mas employees. The population in this study were all employees of PD Sahang Mas, totaling 33 employees. With saturated sampling technique, the number of samples used in this study amounted to 33 employees. The data collection method used was questionnaires using a 5-point Likert scale. The instrument test was carried out using validation and reliability tests. The analysis technique used is simple linear regression analysis using the SPSS application. Based on the results of the analysis it was concluded that the physical work environment has a positive and significant effect on the job satisfaction of PD Sahang Mas employees.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
