    Background: Ectopic pregnancy (EP) is the leading cause of maternal morbidity and mortality in the first trimester and major cause of reduced reproductive potential. Early detection of EP by improved ultrasonography modalities has decreased the rate of rupture and consequent maternal morbidity. Aim was to study the predisposing risk factors in modern scenario and choose the appropriate management available.Methods: A retrospective study on clinical diagnosis and management of EP of patients was carried out between January 2018 to February 2020. Investigations included CBC, UPT, serum β-hCG and TVS. Management was decided after thorough evaluation.Results: Out of 7,780 deliveries, 70 were EP (0.9%). Women with age 21-30 year had highest incidence (85.7%). Common symptoms were abdominal pain (94%), amenorrhea (87%), bleeding per vagina (48%). Most common risk factor associated with EP was PID (28.5%). Tubal EP was most common (84.2%) involving ampulla (66%), isthmus (15%), fimbria (12%), interstitial (7%). Scar ectopic was reported in 10% of cases and ovarian, rudimentary horn and abdominal pregnancy in 1.4% each. About 52.8% of ectopic was ruptured and salpingectomy was done in 74.3% and salpingo-oophorectomy in 2.8%. Five cases of scar EP required hysterotomy and 1 case was managed by methotrexate (MTX).Conclusions: EP remains a major challenge to the obstetrician worldwide. A high index of suspicion is required for early diagnosis and timely intervention in the form of medical or surgical treatment will definitely help in reducing the morbidity and mortality

    Background: Arteriovenous malformation is abnormal connection between an organ’s arterial and venous circulation. In acquired AVM, history of uterine procedure seems inevitable. Their clinical feature is usually vaginal bleeding. It is diagnosed by 2-D ultrasonography combined with colour doppler. Most of the time they resolve spontaneously; however, if left untreated, uterine artery embolization or hysterectomy comes in hand. The purpose of this study was to evaluate the role of TVUS and colour doppler in the diagnosis and follow-up of treated cases of uterine AVM. This study also aims to evaluate different modalities to manage uterine AVM.Methods: This was a retrospective study done at tertiary care centre from January 2018 to December 2019 to assess the presentation, treatment, and clinical pictures of patients with uterine AVM that were diagnosed with TVUS. Authors reviewed both (1) clinical data (2) ultrasound data of patients. The diagnostic criteria were “subjective” with a rich vascular network in the myometrium with the use of colour Doppler images and “objective” with a high PSV of 20 cm/sec in the vascular web.Results: Thirteen patients met the diagnostic criteria mentioned above. Out of that 100% presented with on and off bleeding per vaginum. Recent and remote history of uterine procedures were in found in 84.6% (n=11) of cases. UAE was done in 53.8% (n=7) cases. Thirty-three (33%) (n=5) cases spontaneously resolved when closely monitored with serial imaging and serum beta- HCG levels. Hysterectomy was needed in 7.4% (n=1) of patients of AVM.Conclusions: Uterine AVM occurred after unsuccessful pregnancies or uterine procedures. Triage of patients for expectant treatment, hormonal treatment vs intervention with uterine artery embolization based on their clinical status, which was supplemented by objective measurements of blood velocity measurement in the AVM, appears to be a good predictor of outcome

    Background: Caesarean scar pregnancy (CSP) can be defined as the implantation of the gestational sac within the scar of a previous caesarean surgery. Incidence of CSP is 1 in 1800 pregnancies.Methods: It is a retrospective study based on clinical diagnosis and management of CSP of women who presented to the obstetrics and gynaecology department SVP hospital from January 2008 to August 2021. Total number of cases of CSP were 28. Incidence, gestational age, ultrasound findings, serum β-human chorionic gonadotropin (β-hCG) levels, flow profiles of color Doppler, and different methods of treatment were recorded. Diagnosis was confirmed by ultrasound.Results: In this study, all 28 cases of CSP considered were offered definitive management. In present study 5 cases (17.88%) showed torrential haemorrhage during dilatation and evacuation (D and E) which was treated by various methods like 1 (3.57%) Foley’s tamponade, 1 (3.57%) uterine artery embolization (UAE) and 3 (10.71%) hysterectomy. Hysterotomy was performed in 13 cases (46.42%) and (7.69%) of heterotrophic CSP (HCSP). One case (3.84%) of CSP presented at 26 weeks of gestation with haemorrhagic shock, underwent obstetric hysterectomy.Conclusions: There is a rise in the incidence of CSP because of increase in the global rate of caesarean sections and early transvaginal USG in pregnancy. Transvaginal sonography is the best diagnostic tool. Medical management can be offered when diagnosis is made at gestational age of 7 weeks of gestational age. Surgical management has an advantage of shorter follow up.

    Background: This study is to provide an overview of the clinical course and outcome of COVID in pregnancy in both first wave and second wave, to study about different parameters affected significantly in both waves.Methods: This is a retrospective comparative study that was conducted by dividing the patients into group 1 and group 2. Group 1 was treated in 2020 (wave 1) whereas group 2 in 2021 (wave 2). A laboratory confirmed positive cases of COVID-19 infection in pregnant women were included. All the patients were further categorized into mild, moderate and severe subgroups according to the ICMR criteria. Results: The study of the first (2020) and second (2021) wave of COVID-19. In group 1 and group 2, there were a total of 359 cases and 145 cases respectively. In group 1, there were 54/359 (15.04%) moderate cases and in group 2 there were 17/145 (11.72%) moderate cases. While there were 101/359 (28.13%) and 106/145 (73.10%) severe cases in group 1 and group 2 respectively. Most of severe cases of second group associated with breathlessness, tachypnoea and fall in oxygen saturation level ended with mechanical ventilation by O2 mask (7.54%), NRBM (8.49%), HFNC (14.15%), BIPAP (12.26%), invasive ventilation (22.64%). Conclusions: The results of study show that hospitalized patients in the second wave were younger, required hospitalization, and had higher mortality rates

    Background: WHO has declared COVID-19 infection a health emergency of international concern on 11th March, 2020. It is not clear whether clinical characteristics of pregnant women with COVID-19 differ from those of nonpregnant women and whether it aggravates COVID-19 symptoms and whether antiviral therapy is necessary for COVID-19 infected pregnant women.Methods: This is prospective study of 125 cases based on the compiled clinical data for pregnant women with COVID-19 between 15th April 2020 and 10th June 2020. A laboratory confirmed positive case of COVID-19 infection in pregnant women were included.Results: The most common symptoms at presentation were cough in 61.6% (77/125) and fever in 46.4% (58/125). Other reported symptoms were sore throat in 13.6% (17/125), myalgia in 10.4% (13/125) while 38.4% (48/125) were asymptomatic. There were total 97 deliveries (including 2 twins’ deliveries) among which 3 cases had IUD. Present study reported 96 live births. The incidence of missed abortion was 2.4% (3/125). The incidence of preterm birth before 37 weeks was 8.2% (8/97). Ninety-six (96.9%) of neonates were tested for SARS-CoV-2 viral nucleic acid on nasopharyngeal and pharyngeal samples and 16.67% (16/96) were resulted positive.Conclusions: At present, there is no evidence regarding the greater risk of pregnant women to succumb to COVID-19 infection and experience severe pneumonia. The risks of spontaneous abortion and preterm birth are not increased as reported in this study but shows possibility of vertical transmission when it manifests during the third trimester of pregnancy

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

    Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

    Get PDF
    A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

    Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

    Get PDF
    This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in HERWIG7, and are obtained from a fit to minimum-bias data collected by the CMS experiment at s=0.9, 7, and 13Te. The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the dat

    Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

    Get PDF
    A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

    Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

    Get PDF
    A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV
