Background: The game of water polo has become more familiar to all the athletes and coaches as the time has passed. It has been played as a sport for more than a century Although anatomical shoulder movement strength balance is a crucial factor in overhead throwers’ performance, it has not been studied extensively in the previous research. Objective: This study examined shoulder movement imbalance in bilateral and dominant anterior-posterior shoulder among 42 elite water polo players in Malaysia. Method: The t-test analyses of data obtained through several tests proved that water polo players had statistically significant difference between their right hand anatomical shoulder movement strength and their left hand anatomical shoulder movement strength in all eight shoulder movements, i.e. Flexion, Extension, Abduction, Adduction, Horizontal Adduction, Horizontal Abduction, Rotation and External Rotation. Results: The results of this study showed that there are significant differences of anatomical shoulder movement strength in both bilateral and Anterior-posterior shoulder movement among water polo players. The statistics results for bilateral shoulder movement of Flexion (t= 136.09 and p<.001), Extension (t= 110.92 and p<.001), Abduction (t= 121.89 and p<.001), Adduction (t= 101.47 and p<.001), Horizontal Adduction (t= 92.3 and p<.001), Horizontal Abduction (t= 95.6 and p<.001), Internal rotations (t= 109.6 and p<.001) and External rotations (t= 102.18 and p<.001) showed the p-value to be less than 0.05 for all variables of the test. The result of paired samples t-test showed there is a statistically significant difference between the mean of bilateral anatomical shoulder movement strength among water polo players. Conclusion: These findings suggest that coaches and players should take into account the shoulder movement strength imbalance in their trainings and design specific training programs to improve overhead throwers’ shoulder movement strength balance and hence their throwing performance in sports such as water polo.

Abstract Background Chronic rhinosinusitis (CRS) is a common inflammation of the nose and the paranasal sinuses. Intractable CRS cases are generally treated with endoscopic sinus surgery (ESS). Although the effect of ESS on CRS symptoms has been studied, the pattern of symptom improvement after ESS for CRS is yet to be investigated. The aim of this study was to determine the magnitude and sequence of symptom improvement after ESS for CRS, and to assess the possible preoperative factors that predict surgical outcomes in CRS patients. Methods This was a longitudinal prospective study of 68 patients who had CRS (with or without nasal polyps). The patients underwent ESS at King Fahd Hospital of the University, Al Khobar, Saudi Arabia. The Sino-nasal Outcome Test-22 (SNOT-22) questionnaire was used for assessment at four time points during the study: pre-ESS, 1-week post-ESS, 4 weeks post-ESS, and 6 months post-ESS. Results The difference between the mean scores recorded for the five SNOT-22 domains pre-ESS and 6 months post-ESS were as follows: rhinologic symptoms (t-test = 7.22, p-value =  < 0.001); extra-nasal rhinologic symptoms (t-test = 4.87, p-value =  < 0.001); ear/facial symptoms (t-test = 6.34, p-value =  < 0.001); psychological dysfunction (t-test = 1.99, p-value = 0.049); and sleep dysfunction (t-test = 5.58, p-value =  < 0.001). There was a significant difference between the mean scores recorded for the five domains pre-ESS and 6 months post-ESS. Rhinologic symptoms had the largest effect size (d = 1.12), whereas psychological dysfunction had the least effect size (d = 0.24). The only statistically significant difference in the SNOT-22 mean scores recorded 4 weeks post-ESS was observed between allergic and non-allergic patients (t = − 2.16, df = 66, p = 0.035). Conclusion Understanding the pattern of symptom improvement following ESS for CRS will facilitate patient counselling and aid the optimization of the current treatment protocols to maximize surgical outcomes and quality of life. Level of evidence Prospective observational.

Abstract. The purpose of this research is to compare the efficiency of 11 Sharia Banks in Indonesia and its impact on their performance. This study relies on the quarterly data from 2012-2017 and applied Data Envelopment Analysis to measure their performance. The result of the T-test shows that the P-value for two tail = 0.706. So based on this trend the P-value is greater than α = 0.05 (P-value> α). In the condition of P-value> α, H1 is rejected, meaning that there is no change in the value of efficiency between the period 2012-2014 and the period 2015-2017. This research shows that the efficiency of Islamic banking has not occurred during the implementation of the 2012-2017 Indonesian Sharia Banking Roadmap. Furthermore, the highest efficiency value during the period before implementation was 0.92 with an average efficiency value of 0.57. This means that during this period there was room to increase efficiency by 0.35. Meanwhile the period after implementing the highest efficiency value was 0.87 with an average efficiency value of 0.59. This means that during this period there was room to increase efficiency by 0.28. This means that during the 2012-2017 period, there was no significant difference in efficiency levels during the 2012-2014 period (before the implementation) and the 2015-2017 period (after the implementation of the Islamic banking road map). Keywords: DEA, Efficiency, Sharia Bank Abstrak. Tujuan dari penelitian ini adalah untuk membandingkan efisiensi dari 11 Bank Syariah di Indonesia dan dampaknya terhadap kinerja bank tersebut. Penelitian ini menggunakan data setiap kuartal selama tahun 2012 hingga tahun 2017 dan menggunakan Data Envelopment Analysis untuk mengukur kinerja. Hasil penelitian ini menunjukan bahwa selama implementasi Roadmap, perbankan syariah belum menunjukan kenaikan efisiensi. Sementara itu, sebelum implementasi tersebut, nilai efisiensi tertinggi perbankan syariah sebesar 0,92, sedangkan rata-rata nilai efisiensinya sebesar 0,57. Ini berarti bahwa ada ruang untuk meningkatkan level efisiensi sebesar 0,35. Sedangkan pada periode implementasi, nilai efisiensi tertingi perbankan syariah sebesar 0,87, dan ratarata nilai efisiensinya sebesar 0,59. Ini berarti ada ruang untuk meningkatkan level efisiensi sebesar 0,28. Hasil penelitian juga menunjukan bahwa, secara keseluruhan periode tahun 2012 hingga tahun 2017, hasil t-test menunjukan nilai P-value for two tail = 0.706. Ini berarti P-value> α, dan menolak H1, sehingga tidak terdapat perbedaan level efisiensi selama periode 2012-2014 (sebelum implementasi) dan periode 2015 – 2017 (setelah implementasi) Kata kunci: DEA, Efisiensi, Bank Syariah

Abstractwas to assess efficacy of Tadalafil alone versus Tadalafil plus Pentoxifylline in the treatment of erectile dysfunction by using self administered IIEF-5 questionnaire.Two hundred and thirty seven patients presenting with ED at andrology OPD were evaluated for ED by a self administered IIEF (International Index of Erectile Function) questionnaire. Patients were systematically randomized by computer generated random table into two groups groups namely, group A: Tadalafil only group, group B: combination of Tadalafil + Pentoxifyl-line. All the patients were re-assessed by IIEF-5 questionnaire after 8 weeks of medical therapy. Statistical analysis was performed using student’s unpaired t-test, paired t-test, chi square test. p-value < 0.05 was considered statistically significant.Two hundred and thirty seven patients were included in the present study, in group A: 92 patients (78.6%) showed improvement in their IIEF score after 8 weeks of tadalafil treatment. While in group B, overall 104 patients(86.6%) showed improvement after combination of Tadalafil and Pentoxifylline. There was a statistically significant difference of percentage change in IIEF score was seen in group B (group A 90.7±15.2%, group B 95.6±13.4%; p value – 0.014). We found this difference even more statistically significant in patients with severe ED (group A 72.7±47.2%, group B 132.3±54.3%; p value – 0.000). There was no significant difference in between the two groups with regards to occur-rence of side effects.Both tadalafil and combination of Tadalafil + Pentoxifylline improve erectile function in patients of ED. Patients with severe ED showed much significant improvement in erectile function with combination therapy.
