Ovarian leiomyoma with torsion: a case report
We report an uncommon case of primary ovarian leiomyoma with torsion. Leiomyoma of the ovary is an extremely rare benign solid neoplasm of uncertain etiology. Our patient presented with abdominal pain and imaging showed right adnexal solid mass. All tumour markers except LDH were normal. The patient underwent laparotomy proceed right salpingo-ophorectomy. Intraoperatively, it was found to be twisted right ovarian solid tumour and histopathological examination revealed leiomyoma of ovary
Recurrence of borderline ovarian tumors: a survival analysis
Background: Borderline ovarian tumors are non-invasive tumors that display greater epithelial proliferation and cytological atypia than benign tumors, but less than carcinomas. They may be treated conservatively in young women, however there is a concern for recurrence and progression to frank malignancy. We aimed to study the clinicopathological features of borderline ovarian tumors and their risk of recurrence.Methods: We reviewed the electronic and paper charts of all borderline ovarian tumors operated between January 1, 2001 and December 31, 2019 at a tertiary level teaching hospital in India. Descriptive statistics such as proportions and means were used. A survival analysis was done for recurrence and death.Results: A total of 93 borderline ovarian tumor patients were identified. The most common histology in our study was mucinous 60 (63%) followed by serous 28 (29%). Ninety two (99%) of them were stage I at diagnosis. Microinvasion was present in 27 (26%) of the cases. Out of the 30 fertility sparing operations performed (unilateral salpingo-oophorectomy/cytectomy), 4 (13%) had recurrences and progressed to malignancy. The overall malignancy rate was 4%. There was one mortality secondary to septic shock.Conclusions: Borderline ovarian tumors account for 10-20% of ovarian epithelial tumors and have extremely good prognosis affecting majorly the reproductive aged women. The low recurrence rate and good five year survival rate, at all the stages of the disease enables to incorporate fertility sparing surgeries as part of the staging
PyMorph: Automated Galaxy Structural Parameter Estimation using Python
We present a new software pipeline -- PyMorph -- for automated estimation of
structural parameters of galaxies. Both parametric fits through a two
dimensional bulge disk decomposition as well as structural parameter
measurements like concentration, asymmetry etc. are supported. The pipeline is
designed to be easy to use yet flexible; individual software modules can be
replaced with ease. A find-and-fit mode is available so that all galaxies in a
image can be measured with a simple command. A parallel version of the Pymorph
pipeline runs on computer clusters and a Virtual Observatory compatible web
enabled interface is under development.Comment: 15 pages, 12 figures, 1 table, accepted for publication in MNRA
Photometric Catalogue of Quasars and Other Point Sources in the Sloan Digital Sky Survey
We present a catalogue of about 6 million unresolved photometric detections
in the Sloan Digital Sky Survey Seventh Data Release classifying them into
stars, galaxies and quasars. We use a machine learning classifier trained on a
subset of spectroscopically confirmed objects from 14th to 22nd magnitude in
the SDSS {\it i}-band. Our catalogue consists of 2,430,625 quasars, 3,544,036
stars and 63,586 unresolved galaxies from 14th to 24th magnitude in the SDSS
{\it i}-band. Our algorithm recovers 99.96% of spectroscopically confirmed
quasars and 99.51% of stars to i 21.3 in the colour window that we study.
The level of contamination due to data artefacts for objects beyond is
highly uncertain and all mention of completeness and contamination in the paper
are valid only for objects brighter than this magnitude. However, a comparison
of the predicted number of quasars with the theoretical number counts shows
reasonable agreement.Comment: 16 pages, Ref. No. MN-10-2382-MJ.R2, accepted for publication in

A Call for a Rational Polypharmacy Policy: International Insights From Psychiatrists
OBJECTIVE: Recently, rational polypharmacy approaches have been proposed, regardless of the lower risk and cost of monotherapy. Considering monotherapy as first-line treatment and polypharmacy as rational treatment, a balanced attitude toward polypharmacy is recommended. However, the high prevalence of polypharmacy led the Japanese government to establish a polypharmacy reduction policy. Based on this, the association between the policy and psychiatrists' attitude toward polypharmacy has been under debate. METHODS: We developed an original questionnaire about Psychiatrists' attitudes toward polypharmacy (PAP). We compared the PAP scores with the treatment decision-making in clinical case vignettes. Multiple regression analyses were performed to quantify associations of explanatory variables including policy factors and PAP scores. The anonymous questionnaires were administered to psychiatrists worldwide. RESULTS: The study included 347 psychiatrists from 34 countries. Decision-making toward polypharmacy was associated with high PAP scores. Multiple regression analysis revealed that low PAP scores were associated with the policy factor (β=-0.20, p=0.004). The culture in Korea was associated with high PAP scores (β=0.34, p<0.001), whereas the culture in India and Nepal were associated with low scores (β=-0.15, p=0.01, and β=-0.17, p=0.006, respectively). CONCLUSION: Policy on polypharmacy may influence psychiatrists' decision-making. Thus, policies considering rational polypharmacy should be established
A standardised model for stool banking for faecal microbiota transplantation : a consensus report from a multidisciplinary UEG working group
Background Faecal microbiota transplantation is an emerging therapeutic option, particularly for the treatment of recurrent Clostridioides difficile infection. Stool banks that organise recruitment and screening of faeces donors are being embedded within the regulatory frameworks described in the European Union Tissue and Cells Directive and the technical guide to the quality and safety of tissue and cells for human application, published by the European Council. Objective Several European and international consensus statements concerning faecal microbiota transplantation have been issued. While these documents provide overall guidance, we aim to provide a detailed description of all processes that relate to the collection, handling and clinical application of human donor stool in this document. Methods Collaborative subgroups of experts on stool banking drafted concepts for all domains pertaining to stool banking. During a working group meeting in the United European Gastroenterology Week 2019 in Barcelona, these concepts were discussed and finalised to be included in our overall guidance document about faecal microbiota transplantation. Results A guidance document for all domains pertaining to stool banking was created. This document includes standard operating manuals for several processes involved with stool banking, such as handling of donor material, storage and donor screening. Conclusion The implementation of faecal microbiota transplantation by stool banks in concordance with our guidance document will enable quality assurance and guarantee the availability of donor faeces preparations for patients.Peer reviewe
A preliminary randomized double blind placebo-controlled trial of intravenous immunoglobulin for Japanese encephalitis in Nepal
BACKGROUND: Japanese encephalitis (JE) virus (JEV) is a mosquito-borne flavivirus found across Asia that is closely related to West Nile virus. There is no known antiviral treatment for any flavivirus. Results from in vitro studies and animal models suggest intravenous immunoglobulin (IVIG) containing virus-specific neutralizing antibody may be effective in improving outcome in viral encephalitis. IVIG's anti-inflammatory properties may also be beneficial. METHODOLOGY/PRINCIPAL FINDINGS: We performed a pilot feasibility randomized double-blind placebo-controlled trial of IVIG containing anti-JEV neutralizing antibody (ImmunoRel, 400mg/kg/day for 5 days) in children with suspected JE at two sites in Nepal; we also examined the effect on serum neutralizing antibody titre and cytokine profiles. 22 children were recruited, 13 of whom had confirmed JE; 11 received IVIG and 11 placebo, with no protocol violations. One child (IVIG group) died during treatment and two (placebo) subsequently following hospital discharge. Overall, there was no difference in outcome between treatment groups at discharge or follow up. Passive transfer of anti-JEV antibody was seen in JEV negative children. JEV positive children treated with IVIG had JEV-specific neutralizing antibody titres approximately 16 times higher than those treated with placebo (p=0.2), which was more than could be explained by passive transfer alone. IL-4 and IL-6 were higher in the IVIG group. CONCLUSIONS/SIGNIFICANCE: A trial of IVIG for JE in Nepal is feasible. IVIG may augment the development of neutralizing antibodies in JEV positive patients. IVIG appears an appealing option for JE treatment that warrants further study.
