A Study of Perceptions of Investors Regarding Choice of Assets Allocations and Portfolio Management with Respect to Major Cities of Gujarat Rathod, Harishchandra Singh; Chauhan, Rahul; Librina, Tria Putri; Maseleno, Andino In the contemporary trend investment in various securities is a big question for the investors because of various alternatives are available for the investment in which we can comprise national and international. An objective of this paper is to study the perception of the investors concerning the choice of the asset allocation and portfolio management in the major cities of the Gujarat. For the investment, portfolio management and selection of securities in portfolio is important. In the era of globalization, portfolio management plays an important role in investing in securities. Portfolio management is both art and science. It is much more than the application of a formula on a set of financial information inputs provided by the Financial Advisor to the selection of securities from the catalog or the security analyst. Intention of this paper is to find out the perceptions of the new investment options of assets allocation and the portfolio management in the major cities of the Gujarat and perceptions for selection of the securities because of in Gujarat the cognizance of the investment alternatives is less in compare to other states. For this analytical study primary data is useful source of information, so questionnaire and interview are the best tools for the research. For analysis of the data Fisher’s exact test is used and based on that conclusion of this paper is drawn and the main problem faced by the investors may derive.

A Simple, Objective, and Mathematical Grading Scale for the Assessment of Facial Nerve Palsy Shah, Mohan; Gosai, Alaap; Joshi, Bhavik; Shah, Krupal; Bansal, Pankaj Objectives: It is imperative to acquire a simple, objective, and mathematical method for the assessment of facial nerve palsy which can be universally accepted and implemented. A grading scale which is convenient, continuous and economical was attempted for the first time for global and region-specific assessment of facial nerve palsy. Study Design: Hospital-based observational study. Setting: Medical college hospital. Patients: Ten normal subjects and 51 patients with facial paralysis. Interventions: Patients with facial nerve palsy were graded according to the revised version of House–Brackmann grading system (HBGS-2) and a newly proposed grading system. Main Outcome Measures: The results of the present study were compared with the HBGS-2. Data were analyzed using SPSS-17 (IBM Corporation, New York) for descriptive statistics, normality test, Wilcoxon signed-rank test, and Mann–Whitney U test. Results: The mean time spent on recording measurements was 288 seconds. For the new method and HBGS-2, the modes were graded 3 and 4, corresponding to incomplete facial paralysis. The Kolmogorov–Smirnov normality and Wilcoxon signed rank tests were found significant. In Mann–Whitney U test, probability value indicated that grades of new scale were similar to grades of HBGS-2. Conclusion: The proposed simple, objective and mathematical (SOM) method of grading facial nerve palsy is convenient and provides global and regional continuous percentage that can monitor the progress and classify the patients with facial paralysis into six-point grades based on severity. This system was having substantial compatibility with HBGS-2 grading. For further validity, multi-center study with a larger sample of patients would be required.

Which Headless Compression Screw Produces the Highest Interfragmentary Compression Force in Scaphoid Fracture? Vishwanathan, Karthik; Patel, Ravi; Talwalkar, Sumedh Background : Interfragmentary compression at the fracture site facilitates healing. Headless compression screws used to treat scaphoid fractures can be grouped as shank screws, conical tapered screws and double component screws. There has been no meta-analysis of biomechanical studies to compare interfragmentary compression produced by the above screws. Methods : A computerised search of Pubmed, Embase and OVID database was undertaken to identify the studies. We estimated the weighted mean difference of interfragmentary compression (in Newton) with 95% confidence intervals. Random effects model was selected for meta-analysis. Results : The pooled estimate of nine studies demonstrated that conical tapered screw produced significantly higher interfragmentary compression force compared to the shank screw (WMD 19.96, 95% CI 11.2–28.8, p < 0.0001, I2 = 99%). The pooled estimate of four studies demonstrated that dual component screw produced significantly higher interfragmentary compression force compared to the shank screw (WMD 16.93, 95% CI 12.3–21.6, p < 0.0001, I2 = 97.7%). The pooled estimate of four studies showed that there was no significant difference in the interfragmentary compression force generated by either conical tapered screw or dual component screw (WMD 3.93, 95% CI − 8.3 to 16.2, p = 0.53, I2 = 99.7%). There was evidence of minimal publication bias. Conclusion : Conical tapered screws and dual component screws produced statistically significant higher interfragmentary compression force at the scaphoid fracture site compared to shank screws. There was no difference in the compression force generated by either conical tapered screw or dual component screw.

Psychometric Assessment of Modified Harris Hip Score for Femoral Neck Fracture in Indian Population Vishwanathan, Karthik; Pathan, Shahrukh Khan; Makadia, Ravi; Chaudhary, Chintan Background Objective of the study was to evaluate and compare psychometric properties such as validity, reliability, floor ceiling effects and interpretability of the modified Harris Hip Score (mHHS) and the Forgotten Joint Score (FJS) in patients undergoing bipolar hemiarthroplasty for femoral neck fracture in Indian patients, because this has not been done before. Methods This observational study consisted of 40 consecutively operated patients. Construct validity and reliability were evaluated using correlation coefficient and Intraclass correlation coefficient (ICC), respectively. Interpretability was evaluated by describing mean and standard deviation of mHHS and FJS in five subgroups of patients based on their response to the global rating questions and assessment. Results The mean follow-up duration was 15.7 months ± 10.4. There was very high correlation between mHHS and FJS (r = 0.92, p < 0.0001) suggesting convergent construct validity. The results of correlation coefficient were 100% and 66.7% in accordance with the pre-formulated hypotheses for mHHS and FJS, respectively. mHHS and FJS demonstrated adequate construct validity and inadequate construct validity, respectively. The ICC value for mHHS and FJS was 0.80 (p = 0.005) {adequate reliability} and 0.34 (p = 0.06) {inadequate reliability}, respectively. Both mHHS and FJS-12 demonstrated acceptable level of floor (0% for mHHS and 14.3% for FJS) and ceiling effects (12.5% for both mHHS and FJS). There was significant difference in the mHHS and FJS in the five subgroups of patients suggesting adequate interpretability.
