Total knee arthroplasty at Gaza Strip Palestine: compliance and retrospective comparative study

Background: In Gaza Strip, arthroplasty only performed at our center. This study is to assess the compliance and improve current practices.Methods: Study is based on medical records review of all patients underwent total knee arthroplasty (TKA) between January 2016 and December 2017.Results: Forty eight TKA were performed on 41 patients. Neuraxial anesthesia used in 43 operations (30 spinal, 13 epidural). Tranexamic acid used in 20 operations and those show less frequently decrease in hemoglobin level after surgery and for blood transfusion. Simultaneous bilateral TKA used in one patient. Drain used in 26 operations, 2 of them had infection. No one started physiotherapy at same day surgery, this may be due to repeat doses of Epidural anesthesia, performed surgeries before weekend and using the drain. Delayed physiotherapy is associated with prolong hospitalization and increase suspicion of deep venous tthrombosis. The result from our retrospective comparative study was similar to guidelines.Conclusions: We concluded that there is overall good management of TKA in our hospital according to the best available evidence. We recommend to use the international guidelines like the American Academy of Orthopaedic Surgeons (AAOS) guidelines as a standard guidelines to our Hospital, and increase awareness of our staff to the good practice guidelines. Emphasize the important elements that we have shorten of good practice as listed in the discussion.

The analysis of the effect of tax on profitability indices in listed companies of Tehran Stock Exchange

Profitability is considered as the most complicated feature for a company to be understood and evaluated. These ratios included in profitability are applied for evaluating business capabilities and making the wages in comparison with all cost during a specific period of time. In a more accurate way, the ratios indicate the profitability of a company, having calculated the total costs and tax on revenue, operational efficiency, company pricing policies, assets profitability and company’s shareholders. The approach applied in this research is descriptive-analytic. Using the data of 28 companies listed in Tehran Stock Exchange from 2004 to 2010 and using panel data approach, the tax effects over the paid profitability indices were studied in this paper. The results achieved from all estimation cases point out a negative significant effects on various profitability indices. It should be mentioned that in order to relate the taxes to the profitability indices, the costs and the debts of a corporation can be referred. Results of the study indicated that the debts ratio to asset and the type of the industry showed a negative effect on profitability and capital ratio to asset and the size of the company indicated positive significant effects on profitability index

A note on divergent selection for total fleece weight in adult Angora rabbits: direct response to selection on total fleece weight at first and second harvest

[EN] In order to explore the genetic variability of wool production and other quantitative traits, an 8-cohort divergent selection experiment for total fleece weight (TFW) was carried out in French Angora rabbits. Studies were made on the wool production of a total of 669 female rabbits born between 1994 and 2001 and having produced wool from first to 12th harvests. The aim of the selection experiment was to obtain two divergent lines (low and high) on TFW. From preliminary analysis, the dataset was separated into three subsets according to the harvest number: one for each of the first two harvests and one for the third to the 12th harvests. In this paper, wool production data of the first and second harvests was analysed separately. Response to selection for total fleece weight at 3-12 harvest (TFW3-12) on this trait at first and second harvest was the aim of this paper. The second objective was to study the possibility of utilising values of the first or second harvest to estimate breeding values and as selection criteria for total fleece weight in the French Angora rabbit. Preliminary analysis of the data for non-genetic factors was done by the GLM procedure of SAS. Genetic parameters and breeding value estimates were carried out using a BLUP animal model using ASReml. A linear mixed model for a bivariate analysis of total fleece weight at first or second harvest and TFW3-12 was used. Heritability estimates of total fleece weight at first and second harvests were 0.36 and 0.38, respectively, and were similar to that observed at later harvests (0.35). The genetic correlation between TFW3-12 and fleece weight at first harvest was close to zero indicating that wool production at first harvest is a different trait from that of subsequent harvests. Genetic correlation estimates observed at second harvest were high (0.76) and response to selection at second harvest was similar to that observed for TFW3-12. These observations confirm that total fleece weight at first harvest is a different trait from TFW3-12. In French Angora rabbits, the high genetic correlation between TFW3-12 and total fleece weight at second harvest suggests the possibility of selection at this time for TFW3-12.The authors thank Gérard Auvinet, Jean Claude Musseau and Patricia Bayle of the Institut National de la Recherche Agronomique (INRA), Génétique Expérimentale en Productions Animales, Le Magneraud Poitou-Charentes Research Centre for the collection of data and the supply and care of Angora rabbits.Rafat, S.; Thébault, R.; Bonnet, M.; Deretz, S.; Pena-Arnaud, B.; De Rochambeau, H.; Allain, D.
