Authors: Álvarez Torres Vanesa
Published: November 2022

Muchos estudiantes universitarios se enfrentan por primera vez a la búsqueda de empleo cuando acaban sus estudios de grado y, además, sin haber redactado nunca una carta de presentación o un currículum. Una formación transversal sobre este tipo de cuestiones debería estar presente en los estudios de grado, independientemente del área de conocimiento. En esta propuesta presentamos la integración de este tipo de textos específicos en el temario de tres asignaturas diferentes. Para ello, explicamos la metodología llevada a cabo, los resultados obtenidos y las conclusiones de esta propuesta docente.

Different symmetries, different mechanisms
Authors: Jennings Ben J. , Tseng Tzu-Wei Joy , Ouhnana Marouane , Kingdom Frederick A. A.
Published: November 2022

Three common symmetries exist in the natural visual world: (i) mirror symmetry, i.e., reflections around a vertical axis, (ii) radial symmetry, i.e., rotations around a point, and (iii) translational symmetry, i.e., shifted repetitions. Are these processed by a common class of visual mechanism? Using stimuli comprising arrays of Gaussian blobs we examined this question using a visual search protocol in which observers located a single symmetric target patch among varying numbers of random-blob distractor patches. The testing protocol used a blocked present/absent task and both search times and accuracy were recorded. Search times for mirror and radial symmetry increased significantly with the number of distractors, as did translational-symmetry patterns containing few repetitions. However translational-symmetry patterns with four repeating sectors produced search slopes close to zero. Fourier analysis revealed that, as with images of natural scenes, the structural information in both mirror- and radial-symmetric patterns is carried by the phase spectrum. However, for translational patterns with four repeating sectors, the amplitude spectrum appears to capture the structure, consistent with previous analyses of texture regularity. Modeling revealed that while the mirror and radial patterns produced an approximately Gaussian-shaped energy response profile as a function of spatial frequency, the translational pattern profiles contained a distinctive spike, the magnitude of which increased with the number of repeating sectors. We propose distinct mechanisms for the detection of different symmetry types: a mechanism that encodes local positional information to detect mirror- and radial-symmetric patterns and a mechanism that computes energy in narrowband filters for the detection of translational symmetry containing many sectors.
An extension of the all-Mach number pressure-based solution framework for numerical modelling of two-phase flows with interface
Authors: Kraposhin Matvey , Kukharskii Aleksandr , Victoria  , Shevelev Aleksandr
Published: November 2022

In this paper, we present the extension of the pressure-based solver designed for the simulation of compressible and/or incompressible two-phase flows of viscous fluids. The core of the numerical scheme is based on the hybrid Kurganov — Noele — Petrova/PIMPLE algorithm. The governing equations are discretized in the conservative form and solved for velocity and pressure, with the density evaluated by an equation of state. The acoustic-conservative interface discretization technique helps to prevent the unphysical instabilities on the interface. The solver was validated on various cases in wide range of Mach number, both for single-phase and two-phase flows. The numerical algorithm was implemented on the basis of the well-known open-source Computational Fluid Dynamics library OpenFOAM in the solver called interTwoPhaseCentralFoam.
The source code and the pack of test cases are available on GitHub: https://github.com/unicfdlab/hybridCentralSolvers

Authors: Chaudhari V. M. , Farmer Mayuri
Published: November 2022

This study captured the perceptions of bank branch managers on working of The Gujarat State Co-Operative Agricultural & Rural Development Bank Ltd. (GSCARDB). The managers were asked to rate 30 perceptions to which extent they agree or disagree with each perception statement about GSCARD bank. This study was conducted in six districts of Gujarat State. Primary research among the branch managers was carried out using structured questionnaire. Descriptive analysis, normality checks, one sample t-test etc. are carried out.
The study findings shows that the bank managers have better perceptions on The GSCARDBank about loan sanctioning and disbursement, meeting the needs and providing rebate/incentives to borrowers and support to branches. They have shown lower perception levels about stamp duty charges, rate of interest, competition scenario, technology upgradation and staffing needs, which GSCARD bank can further investigate and take strategic decisions on these lines.

New One-Pot Synthetic Route and Spectroscopic Characterization of Hydroxo-Bridged Stepped-Cubane Copper(II) Complexes
Authors: O. Abosede Olufunso , A. Obaleye Joshua
Published: November 2022

A new convenient and efficient route for the synthesis of two very important hydroxo-bridged stepped-cubane copper complexes viz: [Cu4(bpy)4Cl2(OH)4]Cl2.6H2O (1) and [Cu4(phen)4Cl2(OH)4]Cl2.6H2O (2) have been obtained. This synthetic route from the mononuclear CubpyCl2 complex is easier, more reproducible and afforded the complex in a much higher yield than the other two previously reported procedures which were equally serendipitously discovered. The purity and formation of the complexes were confirmed with elemental (C,H,N) analysis and the details of the UV-Vis, Fourier transform infrared, electrospray ionization mass spectra of both complexes and the single crystal X-ray crystallography of 1 are presented and discussed. X-ray crystallography confirms the absolute structure of the complexes. The complexes were formed via the connection of four copper atoms to four hydroxide bridging ligands and four bipyridyl ligands with two chloride ligands. There are two coordinate environments around two pairs of copper atoms (CuN2ClO2 and CuN2O3) and each copper atom is pentacoordinate with square pyramidal geometry.
Clasificación de universidades en Chile: crítica al modelo histórico y una propuesta a través de clusters
Authors: Alessandri Francisco , Villarroel Tania , Vergara Magdalena
Published: November 2022

La clasificación de universidades es una herramienta de política pública que permite su focalización cuando los grupos son homogéneos. En Chile, el DFL Nº 4 de 1981 diferenció entre universidades creadas antes y después de 1980. Pese a que dicha reforma pretendió facilitar la entrada de nuevas universidades al sistema, perpetuó diferencias en el financiamiento público a universidades a causa de criterios históricos. El propósito de este artículo es evaluar la homogeneidad de los grupos creados por la clasificación señalada y compararla con la de una propuesta alternativa de clasificación. Con este objeto se presenta un nuevo modelo de clasificación empírica de las universidades chilenas, basada esta en resultados de indicadores públicos en docencia e investigación, a través de un algoritmo de clusters de dos etapas con análisis de componentes principales. Luego se evalúa su estabilidad en el tiempo, analizando las desventajas de la clasificación legal vigente. La clasificación presentada genera grupos de universidades más homogéneos y mejor diferenciados entre sí. Al mismo tiempo, la clasificación presenta un alto nivel de estabilidad en un plazo de cinco años, pero también permite cambiar de categoría a universidades de acuerdo a su desarrollo. Se concluye que existen sistemas de clasificación que presentan beneficios sobre el vigente, por lo que se recomienda su modificación.
Tentative Evidence for Transit-timing Variations of WASP-161b
Authors: Yang Fan , Chary Ranga-Ram
Published: November 2022

We report on the detection of transit-timing variations (TTV) of WASP-161b by using the combination of Transiting Exoplanet Survey Satellite (TESS) data and archival data. The midpoint of the transits in TESS data are offset by ∼67 minutes in 2019 January, and ∼203 minutes in 2021 January, based on the ephemeris published in previous work. We are able to reproduce the transit timings from the archival light curve (SSO-Europa; 2018 January) and find that the timing is consistent with the published ephemeris under a constant period assumption. Conversely, we find that the transit midpoint of the SSO-Europa light curve indicates a 6.97 minutes variation at 4.63σ compared to the prediction obtained from TESS timings, and a constant orbit period assumption. The TTVs could be modeled with a quadratic function, yielding a constant period change. The period derivative

is −1.16 × 10−7 ± 2.25 × 10−8 days per day (or −3.65 s yr−1), using timings obtained from SSO-Europa and TESS light curves. Different scenarios, including a decaying period and apsidal precession, can potentially explain these TTVs but they both introduce certain inconsistencies.

We present the results of the broadband X-ray spectral analysis of simultaneous NuSTAR and XMM-Newton observations of four nearby Compton-thick active galactic nuclei (AGN) candidates selected from the Swift Burst Alert Telescope 150 month catalog. This work is part of a larger effort to identify and characterize all Compton-thick (N
H ≥ 1024 cm−2) AGN in the local universe (z ≤ 0.05). We used three physically motivated models—MYTorus, borus02, and UXClumpy—to fit and characterize these sources. Of the four candidates analyzed, 2MASX J02051994-0233055 was found to be an unobscured (N
H < 1022 cm−2) AGN, 2MASX J04075215-6116126 and IC 2227 to be Compton-thin (1022 cm−2 < N
H < 1024 cm−2) AGN, and one, ESO 362−8, was confirmed to be a Compton-thick AGN. Additionally, every source was found to have a statistically significant difference between their line-of-sight and average torus hydrogen column density, further supporting the idea that the obscuring material in AGN is inhomogeneous. Furthermore, half of the sources in our sample (2MASX J02051994-0233055 and 2MASX J04075215-6116126) exhibited significant luminosity variation in the last decade, suggesting that this might be a common feature of AGN.

A new species, Centaurea lovricii, is described and illustrated from the island of Vis (Dalmatia, Croatia). It occurs on northwest-facing calcareous cliffs near the sea, where it grows with several other rare endemic species. Centaurea lovricii is morphologically similar to C. glaberrima and C. divergens of C. sect. Centaurea, from which it differs in having more succulent leaves with larger and less incised leaflets, bigger capitula, larger phyllaries with more developed appendages and denser and undulate fimbriae, larger florets, bigger achenes, and longer pappus. Its morphological features, distribution, ecology, conservation status and taxonomic affinities are examined. In addition, a new iconography and lectotypification for C. glaberrima and C. divergens is provided.

Published: November 2022

Students and researchers might have diverse ideas about and motivations for citizen science (CS) projects. To prevent uncertainty, we address ethical concerns emerging in CS projects and in CS in general, specifically, the transferability of the ethical skills and knowledge gained within academia (e.g. through studying and research conduct). We dedicate these Guidelines for Research Ethics and Research Integrity in Citizen Science primarily to Masters and Doctoral students and their supervisors, to facilitate CS-related research activities (i.e. mainstream CS) in line with the values of academic integrity. Using a pool of 85 papers, we identified nine topics covering 22 customised guidelines and supplemented them with further readings to build more in-depth knowledge.
Current Challenges for the Korean Association of Internal Medicine
Authors: Park Jung-Won
Published: November 2022

Since its establishment in 1945, the Korean Association of Internal Medicine (KAIM) has had a proud history of overcoming challenges with the combined and harmonized endeavors of all KAIM members. KAIM is now facing several issues related to marked social changes in Korea as well as revolutions in medical science and scientific and communications technologies. Furthermore, KAIM shortened the resident training program in 2017. Internal medicine (IM) is an essential discipline for maintaining and improving the health of Korean citizens. However, the Korean Ministry of Health and Welfare lacks initiatives for supporting IM, and the Korean Health Insurance reimbursement policy does not reflect the essential role of IM in health care. This is aggravated by imbalances in hospital resources and skewed notions in patients’ preferences with regard to metropolitan and non-metropolitan areas. Limited preferences in application to subspecialties may be an obstacle for coordinated development of IM. The current generations of students and residents are familiar with online educational lectures and have different needs for educational materials, which are not met by conventional educational materials. Recent experiences in the COVID-19 pandemic have exacerbated or accelerated these changes and problems. From this perspective, I will summarize the challenges that KAIM is now facing, and outline some possible solutions.

Evaluation of left ventricular diastolic function is essential, especially in patients with heart failure with preserved ejection fraction. The American Society of Echocardiography/European Association of Cardiovascular Imaging guidelines were released in 2016. Four principal parameters were used to assess left ventricular diastolic function. However, there are grey areas; the situation is complex. Recently, various other indicators have been employed to explore left ventricular diastolic function.

Published: November 2022

The incidence of nontuberculous mycobacterial pulmonary disease is increasing, and Mycobacterium avium complex (MAC) is the most common causal species. Patients with underlying structural lung disease or an immunosuppressive condition are at increased risk for MAC infections. Endobronchial lesions caused by MAC infection are extremely rare, especially in immunocompetent hosts. Here, we describe a case of a 58-year-old woman with pulmonary infiltration and endobronchial involvement caused by MAC. The patient had shortness of breath and a productive cough. She had undergone surgery and chemoradiotherapy for lung cancer 10 years prior. Radiological findings revealed small centrilobular nodules with consolidation in the right lung and mild stenosis at the right main bronchus. Bronchoscopy revealed yellowish-white caseous necrosis in the right main bronchus. Mycobacterium intracellulare was identified in bronchial washing fluid. She was treated with antimicrobial medications. After 6 months of treatment, bronchial lesions, radiological findings, and symptoms had improved remarkably and she showed culture conversion.

Gilles Deleuze et Qiaoyixue 侨易学 : conditions de possibilité d’une rencontre « interculturelle »
Authors: Heurtebise Jean-Yves
Published: November 2022

Définir les points de contacts possibles entre la philosophie de Gilles Deleuze et la théorie du Qiaoyi semble à la fois prometteur et problématique. Prometteur parce que Deleuze est l’un des philosophes les plus importants de la seconde moitié du XX e  siècle. Mettre en rapport la puissance conceptuelle de la pensée deleuzienne avec le cadre théorique de ce nouveau développement de la pensée chinoise pourrait permettre d’élaborer une nouvelle méthodologie des études transculturelles. Mais cette comparaison est aussi problématique : en effet, les indices d’une relation entre Deleuze (et Guattari) et la pensée chinoise sont assez clairsemés et contradictoires, et au final peut-être assez décevants. Comment dépasser cet obstacle ? Quels types d’outils conceptuels nous pouvons trouver dans la philosophie de Gilles Deleuze pour justifier une telle lecture deleuzienne du Qiaoyixue qui puisse échapper au fait que Deleuze lui-même a placé la pensée chinoise hors du royaume philosophique proprement dit ? Inversement qu’est-ce qui dans la théorie du Qiaoyixue permettrait de « siniser » la pensée deleuzienne permettant d’inclure des éléments de son système conceptuel dans le cadre de cette théorie des transformations induites par les rencontres interculturelles ? Comment fonder historiquement et culturellement la condition de possibilité d’un dialogue entre eux ?
Retour à la frugalité paysanne ?
Authors: Trémon Anne-Christine
Published: November 2022

Le concept de « civilisation écologique » s’est imposé depuis quinze ans dans la rhétorique politique chinoise, tant sur la scène internationale que nationale. Le présent article souligne sa portée développementaliste et interroge sa relation avec l’urbanisation, une priorité pour la RPC. Forgé dans les années 1980 et destiné à accréditer la continuité avec l’ère maoïste tout en légitimant les réformes capitalistes devant déboucher sur le « socialisme de marché », la civilisation écologique est étroitement corrélée au futur urbain et high tech que la Chine ambitionne. Cependant, le concept a connu une inflexion environnementaliste récente qui va de pair avec une réévaluation des valeurs du passé agricole, alors que la paysannerie avait été dévaluée depuis le début des réformes. Dans les villages urbanisés de Shenzhen, d’anciens paysans se retrouvent ainsi à participer aux campagnes d’éducation environnementale qui éduquent les nouveaux urbains à la frugalité paysanne.
Clivage gauche-droite : une théorie universelle
Authors: Fabry Philippe , Portal Léo
Published: November 2022

Les chercheurs en sciences politiques ont proposé des modèles d’explication du clivage politique particulièrement limités dans le temps ou dans l’espace. Notre modèle du clivage gauche-droite permet d’analyser toute communauté politique où un clivage politique a pu se former. Notre analyse empirique de l’histoire de huit pays a validé notre modèle et ses multiples mécanismes : le clivage politique se forme autour de la question de l’ordre établi (1), une classe d’exclus apparaissant à l’extrême gauche du clivage est à l’origine de l’évolution du clivage qui va toujours de l’extrême-gauche à l’extrême-droite (2), lorsque le clivage s’affaiblit, un bloc élitiste se forme au centre et provoque une montée du populisme en réaction (3). Cet article présente les grandes lignes de notre théorie.

Pricing stock loans under the L$ \acute{e} $vy-$ \alpha $-stable process with jumps
Authors: Fan Congyin , Chen Wenting , Feng Bing
Published: November 2022

In this paper, the pricing of stock loans when the underlying follows a L$ \acute{e} $vy-$ \alpha $-stable process with jumps is considered. Under this complicated model, the stock loan value satisfies a fractional-partial-integro-differential equation (FPIDE) with a free boundary. The difficulties in solving the resulting FPIDE system are caused by the non-localness of the fractional-integro differential operator, together with the nonlinearity resulting from the early exercise opportunity of stock loans. Despite so many difficulties, we have managed to propose a preconditioned conjugate gradient normal residual (PCGNR) method to price efficiently the stock loan under such a complicated model. In the proposed approach, the moving pricing domain is successfully dealt with by introducing a penalty term, however, the semi-globalness of the fractional-integro operator is elegantly handled by the PCGNR method together with the fast Fourier transform (FFT) technique. Remarkably, we show both theoretically and numerically that the solution determined from the fixed domain problem by the current method is always above the intrinsic value of the corresponding option. Numerical experiments suggest the accuracy and advantage of the current approach over other methods that can be compared. Based on the numerical results, a quantitative discussion on the impacts of key parameters is also provided.
Assum Livre
Authors: Sapucaia Rosimária , Bidarra Jose , Saldanha Ângela
Published: November 2022

The performance “Assum Livre” integrates a sequence of artifacts first presented for a PhD thesis, “Backyard of Sounds: A Path to Sound Immersion.” It was recently recreated in a cyberspace event, hence its transcription as a cyberperformance. It consists of an artistic proposal that seeks to reflect on freedom and imprisonment, evoking a metaphor that recreates the experience of the lockdown in 2020–2021. The performance is based on streaming a video recorded with the author and singer performing part of Teixeira's and Gonzaga's song, “Assum Preto,” simultaneously with the live performance of the other stanzas of the song. These alternate with the presentation of the lyrics and the materialization of the performer. As a backdrop, the authors have a projection of natural scenery representing freedom, depicting the natural habitat threatened by human intervention, enhanced by the natural soundscapes, and integrating the hybridization of image, sound, and live performance.

The COVID-19 pandemic in India is a phase of worldwide pandemic caused due to SARS-CoV2. India has the largest number of positive cases in Asia and second highest number in the world. India had four different versions of lockdowns with substantial relaxations. During January 2022, India has release completely all the relaxations. However, most of the infected people are suffering a lot from post-COVID-19 syndrome which has long effects even for months. Mainly, the persons with diabetic, cardiac, asthuma, etc. have major threats and impact for the mitigation of post effects of COVID-19. To analyze and prioritize the preventive measures and follow up cares, this paper proposes a multi-criterion decision analysis TOPSIS model integrated with Grey's theory. TOPSIS is one of the most used techniques in manifold important areas that have been providing uncertain solutions. To overcome the uncertainty in symptoms of the post-COVID-19 infection process, Grey's theory has been integrated.

Authors: Huang Jun Xian , Xu Bin Gang
Published: November 2022

The development trend in smart materials has become miniaturization and portability for the last few decades. Therefore, the study on the fabrication and modification of one-dimensional functional fibers has become a popular research field. In this study, we introduce a novel in-situ breath figure (iBF) technique for the preparation of PMMA@HPMs with controllable honeycomb porous microstructures (HPMs) on its surface. Different from the traditional BF method where an outer layer of HPMs will form with the introduced polymer solution, the HPMs formed by the pure solvent-based iBF method is integrated with the material itself, so no mechanical mismatch or interfacial incompatibility will occur. The main influential factors (e.g., immersion time, RH, and temperature) of the iBF are also systematically investigated. Besides, various functional nanomaterials can be directly anchored on the fiber surface during the iBF process, indicating that a kind of advanced fiber with customized functions could be easily achieved by this one-step strategy. Through investigating the formation of iBF-induced HPMs followed by manufacturing of functional fiber that integrated with nanomaterials, this study provides guidance and a new route for the preparation of multifunctional fiber-based materials to meet wider practical requirements.

One of the most common orthopedic injuries is fracture found on the metacarpal bones of the hand. It is composed of 14-28 % emergency room cases in hospitals. Despite its frequent occurrence, they are often neglected which may lead to major disability or deformity that limits movement. This is merely due to the high cost of treatment which includes the usage of an external metacarpal fixator. In this paper, an external metacarpal fixator clamp with additive manufacturing polymer material is evaluated based on scenarios of flexural and compressive load on the metacarpal bone with simulated fracture. The material is selected using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) multi-attribute decision making. Finite Element Analysis (FEA) is also done with increasing load per scenario. The result shows nylon as a suitable polymer additive manufacturing material for external metacarpal fixator. The equivalent stress on the fixator clamp and the deformation at a maximum load of 120 N is less than 1 Mpa and 0.5 mm, respectively. This comprises the suitability of 3D printed polymer material for an external metacarpal application. Future studies of comparison of FEA simulation and actual 3D printed part is recommended.

Making a product from design to finished product is difficult and time consuming job in conventional manufacturing process but in additive manufacturing (AM) it is an easy process. In AM technologies Fused Deposition Modeling (FDM) is an important printing technology to produce components using thermos plastics. Up to date AM technologies are used to make parts in single material, by using this additive manufacturing sandwich parts can be fabricated to improve flexural property of the material. A lightweight core and two thin solid face sheets with strong flexural rigidity at the top and bottom make up sandwich constructions. Sandwich structures have a core that can be developed and updated to meet our needs, which offers up new possibilities in a variety of disciplines. This method can be done with a variety of filaments, PLA having properties such as biodegradability, lack of disagreeable odor when heated, and usual environmental compatibility throughout its life cycle. PLA also produces 10 times less potentially harmful ultra-fine particles than Acrylonitrile Butadiene Styrene. This article concentrated review on PLA and PLA composite materials to improve flexural property

Published: November 2022

One of the traditional clean-energy harvesting solutions is through transducing different mechanical stresses into electrical energy. Generally, the acoustic-to-electric energy conversion of still needs more research investigations to be applicable. In our work, we are targeting to fabricate elastic nanofibers mats via electrospinning method to be used for acoustic harvesting/sensing applications. The targeted mechanically-elastic nanocomposite includes polyvinylidene fluoride (PVDF), which is one of the most famous organic piezo materials, with blended thermoplastic polyurethane (TPU). As TPU supports higher mechanical allowed breaking strain. Then, the synthesized mat has been used as a target for mechanical stresses with resulted piezosensitivity of 667±220 mV/N. Then, the nanofibers mat has been targeted against acoustic signals with different amplitude and frequencies. It has been observed that the synthesized mats can detect or harvest acoustic signals and convert them into output electric voltage. According to acoustic sound input, the synthesized electrospun nanofibers detect output voltage up to 300 mV with increased input audible amplitude and frequency up to 6 kHz, where the harvested voltage has a saturation behaviour beyond that audible frequency. That can open the track for using such nanocomposites in energy harvesting applications from disposable facemasks, filters, and music/noise in different opened and closed areas.

Self-reinforced polymeric composites have numerous advantages over traditional polymers, including increased mechanical strength, fracture toughness, and other mechanical properties. A special type of such composites can be obtained using non-conventional molding techniques. The investigated self-reinforced composites have layered structure, where layers are created by the same material in numerous molding cycles in the manufacturing process, and have gradient mechanical properties. According to this, it is of high interest to investigate structural behavior of these materials under fatigue loading, including temperature effects and fracture mechanisms occurring during fatigue. The results of the performed studies proved complex fracture mechanisms of self-reinforced polymeric composites manufactured using the applied unconventional injection molding technique due to variability of mechanical properties over the thickness.
Contraceptive usage in women requesting emergency contraception in Swaziland
Authors: Sonubi S. A. , Nkombua Lushiku
Published: November 2022

Background: The Kingdom of Swaziland, following the introduction of the National Family Planning Programme in 1973, has witnessed insufficient scientific publications on the contraceptive practices in the country despite documented high fertility rates and low contraceptive prevalence rates. This study was conducted to understand the practices and potential determinants of contraception among Swazi women who requested emergency contraception.Methods: The data were collected over a period of one month and analysed using simple descriptive analysis to summarise the data and bivariate analysis to determine relevant factors associated with the use of contraception.Results: The majority of participants (79%) use contraceptives. Reasons given for not using contraception previously ranged from medical conditions to not being sexually active. Widely used contraceptives are male condoms, injectable hormones and combined oral contraceptives while the least popular are implants, and post-coital pills. Knowledge of contraceptives came mainly from the health facilities, peers and mass media while parents are the least consulted sources. A high percentage (97%) are aware of sexually transmitted diseases (STDs) and that male and female condoms are the best forms of protection against STDs. Demographic and socio-economic variables are not significantly related to the use of contraceptives.Conclusion: The study established that the majority of the participants used some form of contraception and they also delayed their sexual debut up to the age of 18–20 years. The observed changes of increased contraceptive use and later age of sexual debut could be associated with increased levels of education of the participants and the predominant relaxed approach by Protestants and Zionists who are usually tolerant of contraception. The recommendations, based on the findings of this study, would assist with the planning and implementation of future family planning programmes for which this study serves as a foundation.

Rationale:

SARS-CoV-2 has been identified as a highly infective and contagious viral infection. The SARS-CoV-2 pandemic has been spread worldwide and affected more than 210 countries. Globally, the fast spread of novel SARS-CoV-2 variants has been mostly attributed to international travel.

Patient concerns:

We are reporting the genomic evidence of SARS-CoV-2 Eta VOI among two international travelers. Both travelers were males from Nigeria aged 24 and 34 years and both were asymptomatic.

Diagnosis:

The nasopharyngeal swab samples were in both travelers positive by real-time RT-PCR followed by COVIDSeq-NGS.

Interventions:

Paracetamol 3 times daily for 5 days.

Outcomes:

Patient recovered completely within 10 days and discharged after 14 days of quarantine duration.

Lessons:

This report highlights genomic variation of SARS-CoV-2 among the travelers. For managing the present health crisis, molecular identification of viral variants present in different geographical locations will be very helpful.
The characteristics of the residual disease after cervical conization: A retrospective analysis from a tertiary gynecological cancer center
Authors: Giray Burak , Kabaca Canan , Uzun Mine Guray
Published: November 2022

Background:

Patients with a biopsy-confirmed cervical intraepithelial neoplasia 2 and 3 have an increased risk of disease progression to invasive cancer and should be treated with an excisional method. However, after treatment with an excisional method, a high-grade residual lesion may remain in patients with positive surgical margins. We aimed to investigate the risk factors for a residual lesion in patients with a positive surgical margin after cervical cold knife conization.

Methods:

Records of 1008 patients who underwent conization at a tertiary gynecological cancer center were retrospectively reviewed. One hundred and thirteen patients with a positive surgical margin after cold knife conization were included in the study. We have retrospectively analyzed the characteristics of the patients treated with re-conization or hysterectomy.

Results:

Residual disease was identified in 57 (50.4%) patients. The mean age of the patients with residual disease was 42.47 ± 8.75 years. Age greater than 35 years (P = 0.002; OR, 4.926; 95%CI [Confidence Interval] - 1.681-14.441), more than one involved quadrant (P = 0.003; OR, 3.200; 95% CI - 1.466-6.987), and glandular involvement (P = 0.002; OR, 3.348; 95% CI - 1.544-7.263) were risk factors for residual disease. The rate of high-grade lesion positivity in post-conization endocervical biopsy at initial conization was similar between patients with and without residual disease (P = 0.16). The final pathology of the residual disease was microinvasive cancer in four patients (3.5%) and invasive cancer in one patient (0.9%).

Conclusion:

In conclusion, residual disease is found in about half of the patients with a positive surgical margin. In particular, we found that age greater than 35 years, glandular involvement, and more than 1 involved quadrant were associated with the residual disease.
