    Objectives: To evaluate patients of benign prostatic hyperplasia (BPH) preoperatively and identify those who would benefit from surgery, to evaluate outcome of surgery for BPH with respect to symptomatic and objective improvement of patients, and to compare the results of different surgeries for BPH being done different hospitals at Bhopal, which included transurethral resection of the prostate (TURP), transurethral incision of prostate (TUIP)/bladder neck incision (BNI), and Freyer’s prostatectomy? Methods: The present study was carried out at different hospitals of Bhopal. Patients presenting to the surgery outpatient department with symptoms of obstruction, namely, weak urinary stream, frequency hesitancy, intermittency, urgency, nocturia, etc., were included in the study. Some of the subjects included were patients presenting during emergency timings with complaints of retention of urine or occasionally other symptoms. The American Urological Association (AUA) Symptom Index questionnaire was administered to all such patients. They were also evaluated by ultrasound examination and patients having BPH on ultrasound (USG) were further evaluated by uroflowmetry. Results: Prostatic weight correlated well with the maximum urinary flow rates with an inverse relationship. Both maximum and average urinary flow rates (Q max and Qav) were improved by all the three surgeries However, TURP and Freyer’s prostatectomy showed greater improvement as compared to TUIP/BNI. Combination of AUA scoring, USG, and uroflowmetry helped us document improvement in our BPH patients and compared it favorably with other studies. Conclusion: Uroflowmetry was a simple assessment tool easy to learn and use. It was also inexpensive and formed a useful extension to clinical examination providing objective evidence of obstruction. It also helped to indirectly quantity the severity of obstruction. Symptom severity did not correlate with prostate size. Small prostates caused symptoms in the severe range also while even large prostates sometimes caused little symptoms. Prostatic weight correlated well with the maximum urinary flow rates with an inverse relationship

    Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo

    Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70M>70 M⊙M_\odot) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≀0.30 < e \leq 0.3 at 0.330.33 Gpc−3^{-3} yr−1^{-1} at 90\% confidence level.Comment: 24 pages, 5 figure

    The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data during their third observing run, O3, composed of three phases: O3a starting in April of 2019 and lasting six months, O3b starting in November of 2019 and lasting five months, and O3GK starting in April of 2020 and lasting 2 weeks. In this paper we describe these data and various other science products that can be freely accessed through the Gravitational Wave Open Science Center at https://gwosc.org. The main dataset, consisting of the gravitational-wave strain time series that contains the astrophysical signals, is released together with supporting data useful for their analysis and documentation, tutorials, as well as analysis software packages.Comment: 27 pages, 3 figure

    Ultralight vector dark matter search using data from the KAGRA O3GK run

    Get PDF
    Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

    Objective : The aim of this retrospective study is to compile the epidemiological data in patients with acute appendicitis and to analyze statisticsin patients with acute appendicitis to explain the demographic details.Methods: Retrospective study of 100 patients with appendicectomy,fulfilling all the inclusion criteria were included in this study. Following details of patients were recorded like age, sex, socioeconomic status,symptoms, seasonal trend, dietary habits and timing of appendicectomy. Results: Younger age group (21-40 years) was most common age group(66%) with males (n=66, 66%) preponderance. Majority of patient (n=67, 67%) belonged to middle socioeconomic status. Majority ofappendicectomies occurred in summer (n=54, 54%. Appendicitis is more common in non-vegetarian mixed diet persons (n = 66, 66%). 77 (77%)emergency appendicectomy usually performed in comparison to interval appendicectomy (n=23, 23%)Conclusion: Present study concluded thatthere is a correlation between age, sex, socioeconomic status, seasonal trend, dietary pattern and appendicitis. This study gives the informationthat epidemiologic features of acute appendicitis in our institution are same with worldwide dat

    Objective:To determine whether the use of prophylactic antibiotics is effective in the prevention of postoperative wound infection after open tension free repair of inguinal hernia.Methods: 150 Patients with a primary inguinal hernia repair were randomized in two groups .One group given a preoperative single dose of 1.5 g intravenous cephalosporin and the other group was given a placebo. Patients with recurrent hernias, immunosuppressive diseases, or allergies for the given antibiotic were excluded. Infection,seroma ,wound dehiscence etc was defined and their incidence noted. Follow up of the patients were done at I week,2 week and than 1 month.Results: Groups were well matched for all preoperative variables studied, including comorbid conditions. Superficial surgical site infection developed in 2 patients (1.7%) from the antibiotic group and 3 (3.3%) from the placebo group (p = 0.50). One from each group developed deep surgical site infection. Both patients were readmitted and underwent repeated debridement, which eventually resulted in graft loss.Conclusion: A low percentage of wound infection after primary open mesh inguinal hernia repair was found, and there was no significant difference between the antibiotic prophylaxis or placebo group. The results show that in primary hernia repair, antibiotic prophylaxis is not indicated in low-risk patients
