PAP Smear versus Colposcopy in the Absence of HPV-DNA Testing for the Screening of Pre-malignant and Malignant Cervical Lesions

Introduction: The incidence of cervical cancer is very high in developing countries. The extensive use of cervical screening with PAP smear and colposcopy has considerably increased the detection of premalignant and malignant cervical lesions. Methods: This was a hospital-based study conducted over a period of three months. All the patients underwent gynecological examination, PAP smear and colposcopy. In case of abnormal findings in colposcopy or follow-up cytology, patients were advised for cervical biopsy. With reference to the histopathological reports, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of PAP smear and colposcopy were evaluated. Results: The most common cytological result was Negative for Intraepithelial Lesion or Malignancy (NILM, 60%) followed by Atypical Squamous Cells of Undetermined Significance (ASCUS, 10%), Atypical Squamous Cells- cannot exclude High grade lesion (ASC-H, 6%), Low grade Squamous Intraepithelial Lesion (LSIL,10%) and High grade Squamous Intraepithelial Lesion (HSIL, 11%). In colposcopy, 60% of the patients were normal and 40% showed atypical transition zone. Histo-pathological findings among 53 patients were NILM (13.2%), cervicitis (13.2%), Cervical Intraepithelial Neoplasia I (CIN I, 28.3%), CIN II and CIN III (39.6%) and invasive carcinoma (5.66%). The sensitivity, specificity, PPV and NPV of PAP smear were 63.6%, 66.6%, 33.3%, and 87.5% respectively. Similarly sensitivity, specificity, PPV, NPV of colposcopy for abnormal cervical lesions were 87.56%, 15.38%, 76.09% and 28.57% respectively. Conclusion: In the absence of HPV-DNA testing, the combined use of PAP smear and colposcopy to detect premalignant and malignant cervical lesions increases early detection and treatment

Prevalence of Abnormal PAP Smear in Pregnancy: A Hospital-Based Study in Western Nepal

Introduction: Cervical carcinoma is the third most common malignancy worldwide. The World Health Organization in 2014 reported the crude incidence rate of cervical cancer in Nepal as 24.2 per 100,000 women per year. This study was carried out with the aim of finding out the prevalence of cervical smear abnormality in pregnancy. Methods: An observational study was conducted in the department of Obstetrics and Gynecology of a tertiary center for a period of one year from May 2021 to April 2022. All pregnant women up to 28 weeks of gestation who had National Health Insurance coming for antenatal check-ups underwent PAP smear test. The cytological results were reported based on the Bethesda classification system 2001. Results: Of 200 pregnant women enrolled in the study, the Pap smear report revealed that 32% of the study subjects had inflammatory smear showing candidiasis and bacterial vaginosis with reactive inflammatory changes. However, 66.5% of the subjects showed negative for intraepithelial lesion or malignancy and only 0.5% of subjects had signs related to carcinoma cervix in which the subject had a low-grade squamous intraepithelial lesion.  No satisfactory sample was reported in 1% of the subjects. Conclusion: Pap smear during pregnancy not only gives the opportunity to screen but also helps to create awareness

The genome of the protozoan parasite Cystoisospora suis and a reverse vaccinology approach to identify vaccine candidates

Vaccine development targeting protozoan parasites remains challenging, partly due to the complex interactions between these eukaryotes and the host immune system. Reverse vaccinology is a promising approach for direct screening of genome sequence assemblies for new vaccine candidate proteins. Here, we applied this paradigm to Cystoisospora suis, an apicomplexan parasite that causes enteritis and diarrhea in suckling piglets and economic losses in pig production worldwide. Using Next Generation Sequencing we produced an ∼84 Mb sequence assembly for the C. suis genome, making it the first available reference for the genus Cystoisospora. Then, we derived a manually curated annotation of more than 11,000 protein-coding genes and applied the tool Vacceed to identify 1,168 vaccine candidates by screening the predicted C. suis proteome. To refine the set of candidates, we looked at proteins that are highly expressed in merozoites and specific to apicomplexans. The stringent set of candidates included 220 proteins, among which were 152 proteins with unknown function, 17 surface antigens of the SAG and SRS gene families, 12 proteins of the apicomplexan-specific secretory organelles including AMA1, MIC6, MIC13, ROP6, ROP12, ROP27, ROP32 and three proteins related to cell adhesion. Finally, we demonstrated in vitro the immunogenic potential of a C. suis-specific 42 kDa transmembrane protein, which might constitute an attractive candidate for further testing

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia
