Effect of partial weight bearing program on functional ability and quadriceps muscle performance in hemophilic knee arthritis

Recurrent joint bleeding in persons with hemophilia is known to lead to joint damage associated with pain, loss of range of motion and function. The researcher was motivated by the essence of the importance of partial weight bearing program in rehabilitation of lower limb conditions and the lack of literatures regarding these exercises in rehabilitation of hemophilic knee arthritis. The purpose of this study was to investigate the effect of partial weight bearing program on functional ability and quadriceps muscle strength in children with hemophilic knee arthritis. Thirty patients had participated in this study; with age ranged from eight to twelve years. They were randomly assigned into two equal groups. Patients were evaluated pre and post treatment for their functional walking, and isometric strength of quadriceps. The control group (group A) received quadriceps training exercise program, while the study group (group B) received a program of partial weight bearing added to the same exercise program of group A. Treatment was given 3 times/week, every other day, for six consecutive weeks. The results of the study revealed that both groups demonstrated a significant increase in function, as measured by the six minute walking test (6MWT), although there was no significant difference between both groups concerning improvement of function. Quadriceps isometric muscle strength was significantly improved in both groups, in favor of group B (study group). To conclude the partial weight bearing program may be used as a therapeutic intervention for improving functional ability, and muscle performance in children with hemophilic knee arthritis.Keywords: Hemophilic knee arthritis; Partial weight bearing; Functional walking; Quadriceps muscle isometric strength; Quadriceps training exercise progra

The Relationship between Health Locus of Control, Knowledge and Adherence to Antihypertensive Regimen among Woman with Preeclampsi

Abstract Pregnancies complicated by hypertension are associated with increased risk of adverse fetal, neonatal and maternal outcomes. Adherence to therapy is a potent factor in determining the success of a treatment regimen which is affected by determinant factors, high importance of it is the level of knowledge regarding health circumstance and health locus of control. Therefore, this study aimed to identify the relation between knowledge, health locus of control and adherence to antihypertensive regimen among women with preeclampsia. Design a descriptive correlation methodology was used, where a convenient sample of 150 women had preeclampsia, were selected from the outpatient clinic at El Shat by Maternity University Hospital in Alexandria. Tools: two tools were used to collect data; tool1 pregnant women's knowledge and adherence interview schedule and tool 11 multiple health Locus of Control scale. Results clarified that 39.2%of external powerful health locus of control (EPHLC) and 27.3% of internal health locus of control (IHLC) had good total score of knowledge about preeclampsia and its therapeutic regimen.in contrast 70% of women with chance health locus of control (CHLC) had poor knowledge with a statistically significant difference between them (P=0.008). In addition, women with EPHLC had the highest percentage of adherence to the antihypertensive regimen (40.4%) as compared with "IHLC" (29.4%), however women with "CHLC" had the lowest level of regimen adherence (20%), with a statistically significant difference P =0.002. A statistically significant difference was found between the different dimensions of HLC and women's adherence to antenatal checkup. Antihypertensive medication. Urine & hematological analysis and blood pressure checkup in favor of external powerful others health locus of control P= <0.05. In conclusions, pregnant women who adopted external powerful others' health locus of control was significantly had more knowledge and more adherents to the antihypertensive regimen than those who adopted internal and external chance health locus of control. Thus, researcher recommended for Articulating health educational programs based on the health locus of control beliefs for mothers using health promotion models that emphasize on (definition, signs, and symptoms, causes, complication on the mother and fetus) to improve adherence to the antihypertensive regimen

The Pattern of Women's Reliance on Family Planning Providers in Egypt

Understanding choice of family planning provider is fundamental for policy makers and program managers as they seek ways to both improve the coverage and increase the sustainability and efficiency of family planning services for Egypt to achieve its population objectives. This study focuses first on providing a descriptive profile of the patterns of reliance on sources of family planning services during the early 2000s. Binomial logit models are then estimated to obtain a more in depth understanding of the determinants of the choice of family planning providers in Egypt using the 2000 Egypt Demographic and Health Survey. The study offers insights into a number of aspects of family planning service provision about which there has been less previous investigation. There are marked differences in the extent to which Egyptian women rely on public or private providers for family planning services depending on the type of method they are seeking. Among the more important findings is the consistency women display in the choice of provider among women reporting multiple segments of use. With regard to the determinants of the choice of provider for family planning services, perhaps the most interesting finding is that household wealth was not a significant determinant of the choice of provider. This may reflect that private sources met the demand for family planning services of significant proportions of women in rural areas and among those in the low income groups

Smart Touch Radiofrequency Catheter Ablation versus Cryoballoon Ablation of Pulmonary Veins in Patients with Paroxysmal Atrial Fibrillation

AIM: Evaluation of the safety and efficacy of pulmonary veins isolation in patients with paroxysmal atrial fibrillation (AF) using two new different technologies, cryoballoon (CB) ablation and radiofrequency ablation with contact force (CF)-sensing catheters. METHODS: Prospective single-center evaluation, carried out from January 2016 to June 2018 in Critical Care Medicine Department – Cairo University, comparing CF radiofrequency (Thermocool® SmartTouch, Biosense Webster, Inc.) (CF group) with CB ablation (Arctic Front Advance 28 mm CB, Medtronic, Inc.) (CB group), in regards to procedural safety and efficacy, as well as recurrence at 12 months. Overall, 50 consecutive patients were enrolled (25 in each group). RESULTS: The characteristics of patients of both the groups were similar (46.9 ± 11.2 years, the proportion of women 36%, mean documented AF duration 3 ± 2.3 years, mean CHA2DS2-VASc score 1.4 ± 1.3, and mean HAS-BLED 1.4 ± 0.6). Duration of the procedure was significantly lower in the CB group (171.7 ± 15.24 vs. 199.3 ± 18.94 min, p = 0.002), with a longer duration of fluoroscopy and X-ray exposure in the CB group than the CF group but statistically non-significant difference (58.60 ± 11.57 vs. 48.7 ± 13.86 min and 6273 ± 4934 cGy cm² vs. 6853 ± 5069 cGy cm², p = 0.1 and p = 0.2, respectively). Overall complication rate was similar in both groups: 2 (8%) in each group. At 12 months, AF recurrence occurred in 7 patients (28%) in the CF group and in 9 patients (36%) in the CB group (log rank p = 0.682). CONCLUSION: Pulmonary vein isolation using CF-guided RF and second-generation CB leads to comparable single-procedure arrhythmia-free survival at up to 12 months with similar overall complication rate

Rice husk ash (RHA) and palm oil fuel ash (POFA) and soaking times: analysis of compressive strength of porcelain ceramics

Rice husk ash (RHA) and palm oil fuel ash (POFA) is a by-product from agricultural waste produced thousand tonnes every year. This paper presents the use of RHA and POFA as a substitute material for quartz in fabricating an improved porcelain ceramic. The RH was thoroughly washed with distilled water in order to remove adhering soil and dust. After that it was dried in an oven at 100 ºC for 24 hours. Then the dried husk was subjected to the chemical treatment; 2M HCL, 5% solid at 25 ºC before calcinations to increase silica content. Untreated POFA was dried in an oven at 100 ºC for 24 h. It was ground in a ball mill for 1.5 h with the revolution rate of 200 rev/min to reduce the particle size. Untreated POFA was sieved to remove the particles coarser than 50 μm. The POFA was treated by heating it at a temperature of 600 ºC for 1.5 h. The mixed powder was then pressed into pellets at mould pressure (MP) 91 MPa. All the pellets were sintered at the temperature of 1100 ºC for 1 h hour, 2 h hour s and 3 h hours soaking times. It was found that the highest compressive strength occurred at 20 wt% RHA and POFA and a soaking time of 2 h. The increment in the strength could be attributed to the changes in the increase in mullite and critobalite

Magmatic Evolution and Rare Metal Mineralization in Mount El-Sibai Peralkaline Granites, Central Eastern Desert, Egypt: Insights from Whole-Rock Geochemistry and Mineral Chemistry Data

The Ediacaran peralkaline granites, which were emplaced during the post-collisional tectonic extensional stage, have a limited occurrence in the northern tip of the Nubian Shield. In this contribution, we present new mineralogical and geochemical data of Mount El-Sibai granites from the Central Eastern Desert of Egypt. The aim is to discuss their crystallization condition, tectonic setting, and petrogenesis as well as the magmatic evolution of their associated mineralization. Mount El-Sibai consists of alkali-feldspar granites (AFGs) as a main rock unit with scattered and small occurrences of alkali-amphibole granites (AAGs) at the periphery. The AAG contain columbite, nioboaeschynite, zircon and thorite as important rare metal-bearing minerals. Geochemically, both of AFG and AAG exhibit a highly evolved nature with a typical peralkaline composition (A/CNK = 0.82–0.97) and formed in within-plate anorogenic setting associated with crustal extension and/or rifting. They are enriched in some LILEs (Rb, K, and Th) and HFSEs (Ta, Pb, Zr, and Y), but strongly depleted in Ba, Sr, P and Ti with pronounced negative Eu anomalies (Eu/Eu* = 0.07–0.34), consistent with an A-type granite geochemical signature. The calculated TZrn (774–878 °C) temperatures indicate that the magma was significantly hot, promoting the saturation of zircon. The texture and chemistry of minerals suggest that they were crystallized directly from a granitic magma and were later subject to late- to post-magmatic fluids. Both granitic types were most likely generated through partial melting of a juvenile crustal source followed by magmatic fractionation. The lithospheric delamination is the main mechanism which causes uplifting of the asthenospheric melts and hence provides enough heat for crustal melting. The produced parent magma was subjected to prolonged fractional crystallization to produce the different types of Mount El-Sibai granites at different shallow crustal levels. During magma fractionation, the post-magmatic fluids (especially fluorine) contribute significantly to the formation of rare metal mineralization within Mount El-Sibai granites

Synthesis, characterization and catalytic activity of Cu(II), Co(II), Ni(II), Mn(II) and Fe(III) complexes of 4-((3-formyl-4-hydroxyphenyl)diazenyl)-N-(4-methyloxazol-2-yl) benzenesulfonamide

The sulfonamide derivative, 4-((3-formyl-4-hydroxyphenyl)diazenyl)-N-(4-methyloxazol-2-yl) benzenesulfonamide (FDMB), was synthesized and characterized. Additionally, its Cu(II), Co(II), Ni(II), Mn(II) and Fe(III) complexes were prepared and their structures were investigated by elemental analysis, thermal analysis and (IR, electronic and EPR) spectroscopy. The mode of binding indicates that the ligand binds to the metal ion through carbonyl oxygen and OH phenolic with displacement of its proton. The Co(II) complex was applied for the hydrolysis of nerve agent-like compound, bis-(p-nitrophenyl) phosphate (BNPP). The results showed a significant rate enhancement of 2.5 million fold with respect to the auto-hydrolysis of BNPP under the same conditions

MicroRNA-208a: a Good Diagnostic Marker and a Predictor of no-Reflow in STEMI Patients Undergoing Primary Percutaneuos Coronary Intervention

MicroRNA-208a is a cardiac specific oligo-nucleotide. We aimed at investigating the ability of microRNA-208a to diagnose myocardial infarction and predict the outcome of primary percutaneuos coronary angiography (PCI). Patients (n = 75) presented by chest pain were recruited into two groups. Group 1 (n = 40) had ST elevation myocardial infarction (STEMI) and underwent primary PCI: 21 patients had sufficient reperfusion and 19 had no-reflow. Group 2 (n = 35) had negative cardiac troponins (cTns). Plasma microRNA-208a expression was assessed using quantitative polymerase chain reaction and patients were followed for occurrence of in-hospital major adverse cardiac events (MACE). MicroRNA-208a could diagnose of MI (AUC of 0.926). After primary PCI, it was superior to cTnT in prediction of no-reflow (AUC difference of 0.231, P = 0.0233) and MACE (AUC difference of 0.367, P = 0.0053). Accordingly, circulating levels of miR-208a can be used as a diagnostic marker of MI and a predictor of no-reflow and in-hospital MACE
