Impaired geometric properties of tibia in older women with hip fracture history.
2007
This study evaluated side-to-side differences in tibial mineral mass and geometry in women with previous hip fracture sustained on average 3.5 years earlier. Both tibial mineral mass and geometry were found to be reduced in the fractured leg. INTRODUCTION: The purpose of this study was to evaluate side-to-side differences in tibial mineral mass and geometry after hip fracture and to assess the determinants of such differences. METHODS: Thirty-eight 60- to 85-year-old women with a previous hip fracture and 22 same-aged control women without fractures participated in the study. Bone characteristics of the distal tibia and tibial shaft of both legs were assessed using pQCT in order to compare …
Does hysterectomy with ovarian conservation affect bone metabolism and density?
2002
We evaluated whether hysterectomy with ovarian conservation (HYX) has an effect on bone metabolism and density in 176 healthy Caucasian postmenopausal women aged 48-59 years. Bone properties of the hip, spine, radius, tibia, and calcaneus were measured using different bone assessment modalities. In addition, bone turnover was assessed using serum bone-specific alkaline phosphatase (BAP), osteocalcin (OC), and tartrate-resistant acid phosphatase (TRAP) 5b as biomarkers. Our results showed that women having HYX had a significantly lower level of OC ( P = 0.017) and a marginally lower level of TRAP 5b ( P = 0.051) and higher bone mineral density (BMD) of the femoral neck ( P = 0.037) and lumba…
Positive association of high-density lipoprotein cholesterol with lumbar and femoral neck bone mineral density in postmenopausal women.
2021
Abstract Objective Experimental studies suggest that lipids affect bone metabolism. We aimed to elucidate whether lipid levels are associated with bone mineral density (BMD) in a cohort of postmenopausal women. Design A cross-sectional study of participants in the Chronic Ailment Reduction after MENopause (CARMEN) cohort. Women underwent assessment of clinical and analytical parameters, including fasting lipid levels. BMD was assessed at both lumbar spine and hip. Homogeneity in the cohort was optimized by filtering out a series of confounding variables with a known impact on bone. Main outcome measures Association of BMD at lumbar spine and femoral neck with lipid levels. Results A total o…
Biomechanical Bases for Anterior Knee Pain and Patellar Instability
2012
The anterior knee pain syndrome and functional patellar instability in the active young person is one of the most complex knee disorders, with a multiple factor and highly variable pathogenesis, with intermingling mechanical and neurological factors. Probably the neural factor is the cause of the well established symptoms in patients with certain mechanical anomalies and a knee overuse.
Funktionsangiographie der kniegelenknahen Arterien: Konsequenzen für die Stentimplantation?
1990
Angiographic studies of the arteries adjoining the knee in 25 patients show extensive kinking and stenoses of the popliteal artery and less frequently of the distal femoral artery during flexion of the knee joint. This is due to the loss of elasticity with increasing age forcing the vessel into a tortuous course during shortening of the pathway of the popliteal artery with knee flexion. Independent of the principle of the different stents available they probably will not increase the contractility of the stented vessel in the longitudinal axis. It is to expect that after implantation of stents into the popliteal artery kinking will occur predominantly in the original segments of the vessel …
The impact of Nordic walking on bone properties in postmenopausal women with pre-diabetes and non-alcohol fatty liver disease
2021
This study investigated the impact of Nordic walking on bone properties in postmenopausal women with pre-diabetes and non-alcohol fatty liver disease (NAFLD). A total of 63 eligible women randomly participated in the Nordic walking training (AEx, n = 33), or maintained their daily lifestyle (Con, n = 30) during intervention. Bone mineral content (BMC) and density (BMD) of whole body (WB), total femur (TF), femoral neck (FN), and lumbar spine (L2-4) were assessed by dual-energy X-ray absorptiometry. Serum osteocalcin, pentosidine, receptor activator of nuclear factor kappa-B ligand (RANKL) levels were analyzed by ELISA assay. After an 8.6-month intervention, the AEx group maintained their BM…
Bloodstream Infection Incidence of Different Central Venous Catheters in Neonates: A Descriptive Cohort Study
2017
Central venous catheters (CVCs) in neonates are associated with a risk of central line-associated bloodstream infections (CLABSI). Most reports on the incidence of CLABSI in neonates focus on umbilical venous catheters (UVCs) and peripherally inserted central catheters (PICCs). We evaluated the incidence and risk factors for CLABSI in a cohort of neonates with femoral venous catheters (FVCs), UVCs, and PICCs, with a gestational age ≥34 weeks born between January 1, 2006 and June 30, 2013. We included 2,986 neonates with a total of 656 catheters. The CLABSI incidence rate varied from 12.3 per 1,000 catheter-days in FVCs to 10.6 per 1,000 catheter-days in UVCs and 5.3 per 1,000 catheter-days …
Vēlīnie rezultāti un pacienta apmierinatība pēc ceļa locītavas endoprotezēšanas, atkarībā no pielietotās anestēzijas veida
2016
Starp pacientiem pasaulē, kam veikta totāla ceļa locītavas endoprotezēšana, pēc operācijas līdz pat 30% neizjūt nekādus sāpju vai funkcionalitātes uzlabojumus. Daļa pacientu izjūt smagas sāpes pēcoperācijas periodā un daudziem tās saglabājas vēl gadu pēc operācijas. Pētījuma mērķis ir noskaidrot kurš anestēzijas veids: kombinētā spināli epidurālā (KSEA) vai spinālā anestēzija kombinēta ar nervus femoralis katetru (SA+NF), ir saistīts ar viszemākām sāpēm pēcoperācijas periodā, apmēram gadu pēc operācijas un ar vislabāko ceļa locītavas funkcionalitāti, pēc paša pacienta vērtējuma. Otrs mērķis ir identificēt iespējamos riska faktorus, kuru dēļ pacientam var būt neapmierinoši operācijas iznākum…
Evidence of conservative treatment for overuse injuries analysis of systematic reviews
2011
Overuse injuries are common among top athletes and people who exercise regularly. Conservative, non-pharmacological methods are used widely to treat overuse injuries and there is a large body of literature, including multiple systematic reviews, evaluating different terms of treatment. This literature needs summarizing and critiquing. Objective of this study was to evaluate the effectiveness of different methods of conservative treatment on overuse injuries and to provide an analysis of systematic reviews. Published systematic reviews were identified by searching Medline, PEDro, Cochrane and Sportdiscus databases from the year 1996 to July 2010. Reference lists of identified studies were al…
Longitudinal Gait Analysis of a Transfemoral Amputee Patient: Single-Case Report from Socket-Type to Osseointegrated Prosthesis
2023
The aim of the present case report was to provide a longitudinal functional assessment of a patient with transfemoral amputation from the preoperative status with socket-type prosthesis to one year after the osseointegration surgery. A 44 years-old male patient was scheduled for osseointegration surgery 17 years after transfemoral amputation. Gait analysis was performed through 15 wearable inertial sensors (MTw Awinda, Xsens) before surgery (patient wearing his standard socket-type prosthesis) and at 3-, 6-, and 12-month follow-ups after osseointegration. ANOVA in Statistical Parametric Mapping was used to assess the changes in amputee and sound limb hip and pelvis kinematics. The gait symm…
