The Effectiveness of Occupational Therapy Supervised Usage of Adaptive Devices on Functional Outcomes and Independence after Total Hip Replacement in Iranian Elderly: A Randomized Controlled Trial

The aim of this randomized controlled trial was to assess the effect of an occupational therapy protocol of teaching the usage of adaptive devices to older individuals in Iran who have had a total hip replacement as compared with conventional occupational therapy on functional outcomes and independence. Forty individuals diagnosed with osteoarthritis and a total hip replacement aged >60 years were randomly allocated to either control group (n = 20) or experimental (n = 20) group. Pain, disability, independence and hip muscle strength were assessed with visual analogue scale, Western Ontario and McMaster Universities Osteoarthritis and Barthel Index and dynamometer, 2 days before and 6 weeks after the hip operation. Both groups received conventional occupational therapy, but the experimental group was additionally supervised on the use of adaptive devices. Correct use of the devices was instructed during the training session. Both groups significantly improved on all variables post‐operatively. However, the experimental group showed significantly more improvement in all dependent variables post‐operatively. No data were available on the use of the devices by the control group patients. Supervision of the utilization of the adaptive devices during regular home visits by the occupational therapist is recommended. Further research is needed to clarify which aspects of this supervision were most beneficial for the patients. Copyright © 2015 John Wiley & Sons, Ltd.     

Calcinosis cutis complicating liver transplantation

We report a case of calcinosis cutis in a 41-year-old man developing after liver transplantation at sites where no intravenous calcium had been administered. The cutaneous lesions developed on his right upper arm 10-days post-transplantation. The patient had received calcium chloride solution intravenously after surgery. We excluded other causes of ectopic calcification such as hyperparathyroidism, renal failure, and extravasation of calcium chloride.     

Protective effect of essential oil of Pistacia atlantica Desf. on peptic ulcer: role of α-pinene

OBJECTIVE

To evaluate the efficacy of Pistacia atlantica Desf. oleoresin essential oil on peptic ulcer (PU) and its antibacterial effect on metronidazole-resistant Helicobacter pylori, as well as chemical composition of the essential oil.

Synthesis and Biological Evaluation of Cyclic [<Superscript>99m</Superscript>Tc]-HYNIC-CGPRPPC as a Fibrin-Binding Peptide for Molecular Imaging of Thrombosis and Its Comparison with [<Superscript>99m</Superscript>Tc]-HYNIC-GPRPP

Purpose

Many patients worldwide suffer from cardiovascular diseases for which an underlying factor is thrombosis. Devising a molecular imaging technique for early detection of thrombosis in a clinical setting is highly recommended. Because fibrin is a major constituent of clots and is present in all types of thrombi but absent in circulation, it is a highly specific and sensitive target for molecular imaging of thrombi. It is assumed that cyclization of peptides will improve the receptor binding affinity and stability of the peptide. In the present study, we have developed linear and cyclic fibrin-binding peptides for thrombus imaging and compared their biological properties.

Procedures

Linear HYNIC-GPRPP and cyclic HYNIC-CGPRPPC peptides were synthesized using a standard Fmoc strategy and radiolabeled with Tc-99m. The stability of the radiolabeled peptides in human plasma and their affinity for fibrin and blood clots were determined. Blood clearance and biodistribution were evaluated in rats and mice, respectively. The peptide with the highest affinity was injected to a live rabbit femoral thrombosis model, and scintigraphic images were obtained.

Results

In vitro studies show that peptides are stable in human plasma and have a high affinity for human fibrin. They also demonstrated fast blood clearance in rats and high thrombus uptake in the Balb/c mice femoral thrombosis model. Femoral thrombosis was visualized 30 min postinjection of cyclic peptide in a live rabbit model using single photon emission computed tomography (SPECT)/X-ray computed tomography.

Conclusions

The results indicate that the cyclic peptide is a promising agent for molecular imaging of fibrin using SPECT.

     

Acute effects of vinegar intake on some biochemical risk factors of atherosclerosis in hypercholesterolemic rabbits

Background  

Exaggerated postprandial spikes in blood glucose and lipids induce proportional increases in oxidative stress, which acutely trigger impairment endothelial, inflammation and increased risk of future cardiovascular events. In this research, we have investigated acute effects of vinegar intake on some of the biochemical atherosclerosis risk factors in high cholesterol fed rabbits to see if we can find a probable protective value for it.     

Reduced dose of Rh immunoglobulin following first trimester pregnancy termination.

The efficacy and safety of a 50-microgram dose of Rh immune globulin for prevention of Rh isosensitization following first trimester vacuum abortion are evaluated in this study. A total of 1027 women undergoing abortion at three outpatient facilities participated in the study; 755 (73.5%) completed follow-up serologic screening 6 months after termination of pregnancy. None showed serologic evidence of Rh sensitization at the time of followup. No serious adverse reactions to the drug were observed.
