AIM To evaluate whether implant design, glenoid positioning, and other factors influenced instability and scapular notching in reverse total shoulder *** We retrospectively reviewed records of patients who had undergone reverse total shoulder arthroplasty by the senior author from July 2004 through October 2011 and who had at least 24 mo of follow-up. The 58 patients who met the criteria had 65 arthroplasties: 18 with a Grammont-type prosthesis(Grammont group) and 47 with a lateral-based prosthesis(lateral-design group). We compared the groups by rates of scapular notching and instability and by radiographic markers of glenoid position and tilt. We also compared glenoid sphere sizes and the number of subscapularis tendon repairs between the groups. Rates were compared using the Fisher exact test. Notching severity distribution was compared using the χ2 test of association. Significance was set at p p had a higher incidence of scapular notching(13 of 18; 72%) than the lateral-design group(11 of 47; 23%)(p p(0 of 47; 0%)(p = 0.019). Glenoid position, glenoid sphere size, and subscapularis tendon repair were not predictive of scapular notching or instability, independent of implantdesign. With the lateral-based prosthesis, each degree of inferior tilt of the baseplate was associated with a 7.3% reduction in the odds of developing notching(odds ratio 0.937, 95%CI: 0.894-0.983). CONCLUSION The lateral-based prosthesis was associated with less instability and notching compared with the Grammonttype prosthesis. prosthesis design appears to be more important than glenoid positioning.

Effects of Reduced <i>in Utero</i>and post-Weaning Nutrition on Glucose Clearance Measures and Serum Metabolites

引用

Agricultural Sciences 2018年第8期9卷 947-957页

作者： Richard Waterman Mark petersen Thomas Geary Lance Vermeire USDA-ARS Fort Keogh Livestock and Range Research Laboratory Miles City MT USA

Lowering production costs while maintaining an optimal level of production is important to producers in extensive environments. Efforts that strive to match the environment to the nutritional requirements of the grazing animal will substantially improve economic returns to the producer. Therefore, a 3-yr study was implemented that evaluated glucose clearance and serum metabolites in primiparous beef heifers (n = 48;16/yr) from two different feeding regimes. Serum metabolites and glucose clearance measures were analyzed by fitting a repeated measure mixed model using the MIXED procedure of SAS 9.4 (SAS Inst., Inc., Cary, NC). Heifers dams received adequate 1.8 (ADEQ) or marginal 1.2 (MARG) kg/d winter supplementation for approximately 80 d prior to parturition and their heifer calves were then randomly assigned to heifer development treatments that provided ad-libitum (AL) or 80% of ad-libitum (LAL) feed post weaning. Heifers that received the AL treatment during the developmental period were then assigned the 1.8 kg/d winter supplementation for life, whereas heifers that received the LAL treatment during development were assigned the 1.2 kg/d winter supplementation for life. peak glucose concentrations in response to a bolus dose of glucose changed in magnitude between ADEQ and MARG in utero treatments and decreased further removed from parturition (p = 0.05). However, these changes did not manifest along with other glucose clearance measures (p > 0.17) indicating that regardless of in utero treatment or heifer development treatment the reduction in feed input did not greatly influence glucose clearance measures or baseline serum metabolites throughout postpartum, first parity period.

Background: CNS lesions that are acquired early in life e.g. cerebral palsy (CP) disturb muscle development and growth, while CNS injuries acquired later in life e.g. strokepan>pan>,pan>pan> affect fully matured muscles and cause paresis and atrophy. These differences may result in different contracture phenotypes. Aim: The purpose of this study was to compare systemic biomarkers and gene expression levels in muscle of individuals with CNS lesions acquired early and later in life. Methods: Blood samples and muscle biopsies were analyzed using Enzyme-linked immunosorbent assay and Real-time pCR from n = 24 control participants, n = 14 individuals with cerebral palsy, and n = 12 stroke survivors. Results: Systemic markers: Myostatin was significantly decreased in both the cerebral palsy (p = 0.0051), and the stroke group (p = 0.036). Creatine Kinase-MB and C-Reactive protein were significantly elevated in stroke patients only (p p > 0.034 respectively). Gene expressions: The expression of myostatin (MSTN) was significantly lower in both the ST and the Cp group when compared to Ctrl (p = 0.02). In addition, collagen type 4A1 (COL4A1) was significantly lower in the Cp group compared to the other groups (p = 0.015). Finally, the troponin 1 slow skeletal muscle type was significantly increased in the ST group when compared to both Cp and Ctrl (p = 0.03). Conclusion: The downregulation of myostatin in individuals with both early and late CNS injury is likely a compensatory reaction to muscle weakness, reduced muscle mass and/or muscle atrophy. Changes in gene expression may reflect a specific alteration depending on when in life the CNS lesions were acquired.pan>p
