Angiotensin-converting enzyme inhibitors in adults after the Mustard procedure

Angiotensin-converting enzyme inhibitors had no significant effect on cardiopulmonary exercise function in 14 patients who had undergone a Mustard operation for transposition of the great arteries. In some patients aerobic capacity improved and maximum systolic blood pressure decreased.     

Physical therapy and mobility 2 and 6 months after hip fracture

OBJECTIVES: To examine the relationship between early physical therapy (PT), later therapy, and mobility 2 and 6 months after hip fracture. DESIGN: Prospective, multisite observational study. SETTING: Four hospitals in the New York City area. PARTICIPANTS: Four hundred forty-three hospitalized older patients discharged after surgery for hip fracture in 1997-98. MEASUREMENTS: Patient demographics, fracture type, comorbidities, dementia, number of new impairments at discharge, amount of PT between day of surgery and postoperative day (POD) 3, amount of therapy between POD4 and 8 weeks later, and prefracture, 2-, and 6-month mobility measured using the Functional Independence Measure. RESULTS: More PT immediately after hip fracture surgery was associated with significantly better locomotion 2 months later. Each additional session from the day of surgery through POD3 was associated with an increase of 0.4 points (P=.032) on the 14-point locomotion scale, but the positive relationship between early PT and mobility was attenuated by 6 months postfracture. There was no association between later therapy and 2- or 6-month mobility. CONCLUSION: PT immediately after hip fracture surgery is beneficial. The effects of later therapy on mobility were difficult to assess because of limitations of the data. Well-designed randomized, controlled trials of the effect of varying schedules and amounts of therapy on functional status after hip fracture would be informative.     

Immunomodulatory Activities of HERBSnSENSES™ Cordyceps — in Vitro and in Vivo Studies

The commercially available HERBSnSENSES? Cordyceps (HSCS) belongs to a cultivated strain of Cordyceps sinensis whose immunomodulatory activities has been renowned in traditional Chinese medicine (TCM) for centuries. The present report is the first that describes its immunomodulatory features through a series of in vitro and in vivo experiments. We measured, in peripheral blood mononuclear cells the in vitro effects of HSCS on the gene expression of cytokines and cytokine receptors, cytokine release, and surface expression of cytokine receptors using cDNA expression array, cytometric bead array (CBA), and immunoflorescence staining, respectively, as well as macrophage phagocytosis and monocyte production of H₂O₂ using flow cytometry. Sixty female BALB/c mice were fed with either HSCS (40 mg/kg/day) or water consecutively for 14 days. Proliferation, cytokine liberation, and CD3/4/8 expression of splenic cells were measured using 5-bromo-2′-deoxyuridine proliferation ELISA, CBA, and cytometry immunoflorescence staining, respectively. In vitro results demonstrated that HSCS induced the production of interleukin(IL)-1β, IL-6, IL-10 and tumor necrosis factor alphaα from PBMC, augmented surface expression of CD25 on lymphocytes, and elevated macrophage phagocytosis and monocyte production of H₂O₂. In vivo results showed that HSCS did not induce splenomegaly and cytokine overliberation. Our results possibly provide the biochemical basis for future clinical trials.     

A Three‐wave Study of Antecedents of Work–Family Enrichment: The Roles of Social Resources and Affect

On the basis of conservation of resources theory (Hobfoll, 1989 ) and the resource‐gain‐development perspective (Wayne, Grzywacz, Carlson, & Kacmar, 2007 ), this paper examines the differential impact of specific social resources (supervisory support and family support) on specific types of affect (job satisfaction and family satisfaction, respectively), which, in turn, influence work‐to‐family enrichment and family‐to‐work enrichment, respectively. A sample of 276 Chinese workers completed questionnaires in a three‐wave survey. The model was tested with structural equation modelling. Job satisfaction at time 2 partially mediated the relationship between time 1 supervisory support and time 3 work‐to‐family enrichment (capital), and the effect of supervisory support on work‐to‐family enrichment (affect) was fully mediated by job satisfaction. Family satisfaction at time 2 fully mediated the relationship between time 1 family support and time 3 family‐to‐work enrichment (affect, efficiency). Implications for theory, practice and future research are discussed. Copyright © 2013 John Wiley & Sons, Ltd.
