Giriş ve Amaç: Bu çalışmamızda, düşük tehdidi ile başvuran hastaların hangilerinin düşükle sonuçlanacağını öngörebilmek için tam kan sayımı parametrelerinin araştırılması planlanmıştır.
Gereç ve Yöntem: Bu retrospektif kohort çalışmasına abortus imminens tanısı olan 205 kadın hasta dahil edilmiştir. Birinci grupta abortus imminens tanısı olan ve düşük yapan hastalar, ikinci grupta ise abortus imminens tanısı olan ve gebeliği devam eden hastalar olmak üzere hastalar gebelik sonucuna göre iki gruba ayrılmıştır. Hastaların hastaneye başvuruları sırasında bakılan tam kan sayımı parametrelerinden hemoglobin (Hgb), hematokrit (Hct), trombosit (Plt), beyaz kan hücreleri(WBC), nötrofil, lenfosit, ortalama trombosit hacmi (MPV), trombosit dağılım genişliği (PDW) değerleri kaydedilmiş ve platelet-lenfosit oranı (PLR), nötrofil-lenfosit oranı (NLR), monosit-lenfosit oranı (MLR), sistemik inflamatuar index (SII) gibi değerler hesaplanıp kaydedilmiştir.
Bulgular: Bu çalışmada, gebelik sonucu düşükle sonuçlanan grubun yaşı, 30 (27-36), gebelik sonucu doğum ile sonuçlanan gruba göre, 29 (25-33), anlamlı olarak daha yüksek olduğu saptanmıştır (p=0.021). Abortus grubunun parite sayısı, doğumla sonuçlananlara göre yüksek bulunmuştur ( 1(0-2) vs 1(0-1); p=0,017). Doğum grubunda yaşayan çocuk sayısı abortus grubundan yüksek bulunmuştur (1(1-2) vs 1(0-2); (p=0.021). Diğer demografik veriler açısından gruplar arasında anlamlı fark bulunamamıştır (p>0.05). abortus imminens tanısı olanlarda, gebelik sonuçlarını öngörmede tam kan sayımı parametrelerinde istatistiksel anlamlı bir fark saptanmamıştır (p>0.05).
Sonuç: Düşük tehdidi ile başvuran hastalarda tam kan sayımı parametrelerini araştırdığımız bu çalışmada, gebelik sonucu düşük ile sonuçlanan ve gebelik sonucu doğumla sonuçlanan gruplar arasında tam kan sayımı parametreleri açısından istatistiki olarak anlamlı fark bulunamamıştır. Sonuç olarak düşük gelişecek hastaları öngörmede, tam kan sayımı parametrelerinin klinik kullanımı mümkün görünmemektedir.

Aims: To evaluate the placental pathologies of pregnant women diagnosed with COVID-19 according to disease severity.
Materials and method: This retrospective study was conducted at a tertiary center between April 2020 and February 2023. The placentas of 125 pregnant women in their third trimester who were positive for SARS-CoV-2 were examined. Placental pathologies were classified according to the modified Amsterdam criteria. According to the disease severity, the patients were divided into two groups: non-severe COVID-19 (n=104) and severe COVID-19 (n=21). Placental pathology results were compared between the two groups.
Results: The rates of maternal vascular malperfusion (MVM) and fetal vascular malperfusion (FVM) were 90.4% and 45.2% in the non-severe COVID-19 group. Whereas it was significantly lower at 71.4% and 19% in the severe COVID-19 group (p=0.018 and p=0.026, respectively). The rate of delayed villous maturation (DVM) was 9.5% in the severe COVID-19 group and 1% in the non-severe COVID-19 group, indicating a statistically significant difference (p=0.019). Inflammatory pathologies and other pathological findings were similar between the two groups. Intensive care unit (ICU) admission, presence of accompanying maternal diseases, and postpartum complications were statistically significantly higher in the severe COVID-19 group (p
Confirming Resonance in Three Transiting Systems

Published: July 2023

Abstract
Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics. Here, we perform such a study for five multiplanet systems: Kepler-226, Kepler-254, Kepler-363, Kepler-1542, and K2-32. For each system, we run a suite of N-body simulations that span the full parameter space that is consistent with the constrained orbital and planetary properties. We study the stability of each system and look for resonances based on the libration of the critical resonant angles. We find strong evidence for a two-body resonance in each system; we confirm a 3:2 resonance between Kepler-226c and Kepler-226d, confirm a 3:2 resonance between Kepler-254c and Kepler-254d, and confirm a three-body 1:2:3 resonant chain between the three planets of Kepler-363. We explore the dynamical history of two of these systems and find that these resonances most likely formed without migration. Migration leads to the libration of the three-body resonant angle, but these angles circulate in both Kepler-254 and Kepler-363. Applying our methods to additional near-resonant systems could help us identify which systems are truly resonant or nonresonant and which systems require additional follow-up analysis.
Evolution of the Radial Size and Expansion of Coronal Mass Ejections Investigated by Combining Remote and In Situ Observations

Abstract
A fundamental property of coronal mass ejections (CMEs) is their radial expansion, which determines the increase in the CME radial size and the decrease in the CME magnetic field strength as the CME propagates. CME radial expansion can be investigated either by using remote observations or by in situ measurements based on multiple spacecraft in radial conjunction. However, there have been only few case studies combining both remote and in situ observations. It is therefore unknown if the radial expansion in the corona estimated remotely is consistent with that estimated locally in the heliosphere. To address this question, we first select 22 CME events between the years 2010 and 2013, which were well observed by coronagraphs and by two or three spacecraft in radial conjunction. We use the graduated cylindrical shell model to estimate the radial size, radial expansion speed, and a measure of the dimensionless expansion parameter of CMEs in the corona. The same parameters and two additional measures of the radial-size increase and magnetic-field-strength decrease with heliocentric distance of CMEs based on in situ measurements are also calculated. For most of the events, the CME radial size estimated by remote observations is inconsistent with the in situ estimates. We further statistically analyze the correlations of these expansion parameters estimated using remote and in situ observations, and discuss the potential reasons for the inconsistencies and their implications for the CME space weather forecasting.
Finite Temperature Description of Fermi Gases with In-medium Effective Mass
Authors: Dutra Mariana , Lourenço Odilon , Margueron Jérôme 
Published: July 2023

Abstract
We investigate Fermi gases at finite temperature for which the in-medium effective mass may not be constant as a function of the density, the temperature, or the chemical potential. We suggest a formalism that separates the terms for which the mass is constant from the terms that explicitly treat the correction due to the in-medium effective mass. We employ the ensemble equivalence in infinite matter to treat these different terms. Our formalism is applied in nuclear matter and we show its goodness by comparing it to an exact treatment based on the numerical calculation of the Fermi integrals.

Abstract
We present the analysis of the magnetic field (B-field) structure of galaxies measured with far-infrared (FIR) and radio (3 and 6 cm) polarimetric observations. We use the first data release of the Survey of extragALactic magnetiSm with SOFIA of 14 nearby (

). For spiral galaxies, FIR B-fields are 2%–75% more turbulent than the radio B-fields. For starburst galaxies, we find that FIR polarization is a better tracer of the B-fields along the galactic outflows than radio polarization. Our results suggest that the B-fields associated with dense, dusty, turbulent star-forming regions (those traced at FIR) are less ordered than warmer, less dense regions (those traced at radio) of the interstellar medium. The FIR B-fields seem to be more sensitive to the activity of the star-forming regions and molecular clouds within a vertical height of a few hundred parsecs in the disk of spiral galaxies than the radio B-fields.
Particles in Relativistic MHD Jets. I. Role of Jet Dynamics in Particle Acceleration
Authors: Dubey Ravi Pratap , Fendt Christian , Vaidya Bhargav 
Published: July 2023

Abstract
Relativistic jets from (supermassive) black holes are typically observed in nonthermal emission, caused by highly relativistic electrons. Here, we study the interrelation between three-dimensional (special) relativistic magnetohydrodynamics, and particle acceleration in these jets. We inject Lagrangian particles into the jet that are accelerated through diffusive shock acceleration and radiate energy via synchrotron and inverse Compton processes. We investigate the impact of different injection nozzles on the jet dynamics, propagation, and the spectral energy distribution of relativistic particles. We consider three different injection nozzles—injecting steady, variable, and precessing jets. These jets evolve with substantially different dynamics, driving different levels of turbulence and shock structures. The steady jet shows a strong, stationary shock feature, resulting from a head-on collision with an inner back-flow along the jet axis—a jet inside a jet. This shock represents a site for highly efficient particle acceleration for electrons up to a few tens of TeV and should be visible in emission as a jet knot. Overall, we find that the total number of shocks is more essential for particle acceleration than the strength of the shocks. The precessing jet is most efficient in accelerating electrons to high energies reaching even few hundred TeVs, with power-law index ranging from 2.3 to 3.1. We compare different outflow components, such as the jet and the entrained material concerning particle acceleration. For the precessing nozzle, the particle acceleration in the entrained material is as efficient as that in the jet stream. This is due to the higher level of turbulence induced by the precession motion.

Abstract
Galactic science encompasses a wide range of subjects in the study of the Milky Way and Magellanic Clouds, from young stellar objects to X-ray binaries. Mapping these populations, and exploring transient phenomena within them, are among the primary science goals of the Vera C. Rubin Observatory’s Legacy Survey of Space and Time. While early versions of the survey strategy dedicated relatively few visits to the Galactic Plane region, more recent strategies under consideration envision a higher cadence within selected regions of high scientific interest. The range of galactic science presents a challenge in evaluating which strategies deliver the highest scientific returns. Here we present metrics designed to evaluate Rubin survey strategy simulations, based on the cadence of observations they deliver within regions of interest to different topics in galactic science, using variability categories defined by timescale. We also compare the fractions of exposures obtained in each filter with those recommended for the different science goals. We find that the baseline_v2.x simulations deliver observations of the high-priority regions at sufficiently high cadence to reliably detect variability on timescales >10 days or more. Follow-up observations may be necessary to properly characterize variability, especially transients, on shorter timescales. Combining the regions of interest for all the science cases considered, we identify those areas of the Galactic Plane and Magellanic Clouds of highest priority. We recommend that these refined survey footprints be used in future simulations to explore rolling cadence scenarios, and to optimize the sequence of observations in different bandpasses.
Un silence sans ambiance. Hammershøi, les impressionnistes et le tournant atmosphérique contemporain
Authors: Choplin Hugues 
Published: July 2023

Cet article entend problématiser, dans une perspective esthétique, le « tournant atmosphérique » contemporain. À partir d’une confrontation entre la peinture française impressionniste et la peinture du danois Vilhelm Hammershøi (1864-1916), nous distinguons trois concepts, porteurs, pensons-nous, de trois voies esthétiques différentes : — l’ambiance, adéquate aux impressionnistes et aux philosophies de la situation ou, comme nous le dirons, de l’autour ; — l’atmosphère, engagée par le questionnement de la peinture que déploie une certaine philosophie française du XXe siècle (Deleuze, Merleau-Ponty, Levinas) ; — enfin, le silence, propre à la peinture d’Hammershøi. Dans quelle mesure ce silence, sans ambiance ni atmosphère, peut-il annoncer un art du commun irréductible au tournant atmosphérique ?
De la violence familiale à la violence institutionnelle. Le continuum des violences dans l’expérience des jeunes placés en protection de l’enfance
Authors: Lacroix Isabelle , Chaïeb Sarra , Dietrich‑Ragon Pascale , Frechon Isabelle 
Published: July 2023

Depuis cinq ans, plusieurs rapports et témoignages d’anciens enfants placés interpellent les pouvoirs publics sur les violences subies par les enfants et jeunes dans des institutions de protection de l’enfance. Pourtant, leur parole peine à être entendue. À partir d’une enquête par questionnaires et entretiens (l’enquête longitudinale sur les conditions de vie et de sortie des jeunes du système de protection de l’enfance, ELAP), cet article s’intéresse au continuum des situations de violences – avant et pendant le placement – auquel ont été confrontés les jeunes rencontrés. Nous verrons que, dans certains cas, les établissements et familles d’accueil participent à produire ou à prolonger les violences auxquelles ils devraient pourtant mettre fin.
Rapports d’âge et vulnérabilités aux violences. Le cas des hommes ayant subi des violences sexuelles dans l’enfance
Authors: Wicky Lucie 
Published: July 2023

En s’appuyant sur l’analyse quantitative de l’enquête Virage et des entretiens biographiques réalisés avec certains répondants, cet article explore les rapports d’âge qui s’exercent lorsque les garçons subissent des violences sexuelles avant 18 ans. Les situations de violence illustrent la domination d’hommes adultes ou plus âgés, qui bénéficient des différences statutaires liées à l’âge et du pouvoir lié à la différence de position dans le parcours de vie par rapport aux garçons. Ces rapports de force s’inscrivent dans des structures familiales et sociales qui favorisent l’exercice des violences, leur maintien et le silence qui les entoure. L’article montre ainsi que les rapports d’âge sont multidimensionnels, s’imbriquent avec les rapports de genre et favorisent les violences et la silenciation des garçons qui les subissent. Ils constituent des facteurs de vulnérabilité pour les garçons qui font l’expérience de violences sexuelles dans l’enfance.

Authors: Olorunfemi Olaolorunpo , Sule Oluwakemi Blessing 
Published: July 2023

Background:
After puberty, breast cancer affects women of all ages in different regions of the world that cause a significant threat to public health. Its treatment is likely to be successful if it is discovered early.

Aim:
The aim of the study was to see how well undergraduate students at Achievers University know, feel about, and practice breast self-examination (BSE).

Materials and Methods:
Convenience sampling was used to choose the sample size (n = 333) for a descriptive cross-sectional study that lasted from September 2022 to December 2022. Statistical Package Service Software (SPSS) version 23.0 was used to evaluate the data by employing tables, percentages, and Chi-square test statistics were used at the 0.05 level of significance.

Results:
With a mean age of 20.1 years, 73.3% of the 333 female nursing students were between the ages of 19 and 21. The majority of respondents (95.8%) had a positive attitude and a solid understanding of BSE. In addition, this study demonstrates a strong correlation (χ2 = 38.10, df = 8, and P > 0.001) between knowledge of BSE and level of education. However, there is no correlation (χ2 = 9.76, df = I, and P = 0.08) between respondents’ level of BSE knowledge and practice.

Conclusions:
The study’s findings showed that there is low BSE practice; thus, we recommend putting more of an emphasis on health education.

Published: July 2023

Background:
Self-care practices in diabetes are deemed as one of the mainstays of management, but often poorly practiced by people with diabetes.

Aim:
The study describes self-care practices among adult diabetics registered with a primary health-care setup.

Methods:
This was a community-based cross-sectional study based out of the Ramaiahguda primary health center in Vikarabad town of Telangana. Informed consent was taken from all participants before the commencement of the study. All eligible candidates were approached for the study. The seven domains of the “American Association of Diabetes Educators measures of outcome” were taken as the base for assessment of self-care practices among the participants.

Results:
The mean (standard deviation [SD]) age of the 155 study participants was 50.8 years (SD 12.4 years). Among the various components of self-care, drug adherence, glucose monitoring, and diet modifications were regular as per the advice. Comparatively, healthy coping, risk reduction, and problem solving are the areas where the participants had a major scope to improve. The median self-care score of the participants was 15.25 (interquartile range 14.5–16.25) ranging from 0.25 to 18.0. 86 (55.5%) participants had good self-care scores, and 69 (44.5%) participants had moderate self-care scores.

Conclusions:
The observations from our study point toward a lack of understanding and in-depth evaluation of the effectiveness of diabetic self-care practices, which may in turn be one of the factors affecting compliance to such practices among the diseased population.

Published: July 2023

Abstract

Background
Coronavirus disease 2019 (COVID-19) is a severe infectious disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Regarding the ongoing spread of COVID-19 in Egypt, this study aimed to determine the sensitivity and specificity of rapid COVID antigen swab in the diagnosis of COVID-19 infection in pulmonary and extrapulmonary manifestations of COVID-19 and discuss the pulmonary and extrapulmonary symptoms of COVID-19.

Patients and methods
This is a cross-sectional study performed on 447 patients diagnosed with COVID-19 at the chest out-patient clinic or Department of Chest and ICU in Menoufia University Hospital during the period from July 2021 to March 2022. Detailed history, full laboratory data, high-resolution computed tomography, and rapid antigen swab were obtained.

Results
A total of 447 patients were included in this study. They were classified into two groups: group 1 included 105 patients with pulmonary symptoms and group 2 included 342 patients with extrapulmonary symptoms in the absence or presence of pulmonary symptoms. The current study showed a sensitivity of 88.6% and specificity of 100% regarding the rapid antigen swab in diagnosing COVID-19. Regarding the extrapulmonary symptoms, muscle ache was the most common symptom in 52% of the patients followed by loss of taste and smell in 39.8% of patients.

Conclusion
Rapid antigen tests are practical, are reliable, provide fast results (~15 min), and are cheap diagnostic methods with high sensitivity and specificity for COVID-19.
Moreover, it showed a wide range of extrapulmonary symptoms of COVID-19, and every symptom revealed should be suspected and investigated.

Published: July 2023

Abstract

Purpose
The aim of this study is to detect the prevalence of obstructive sleep apnea syndrome (OSAS) in patients having lone atrial fibrillation (AF).

Patients and methods
Fifty patients with lone AF were referred to our sleep unit from the Department of Cardiology at the University Hospital. Lone AF was defined as AF in patients without cardiac structural abnormality and less than 60 years of age.
All patients were subjected to a detailed history with stress on the number and date of documented episodes of AF and how it was terminated, OSA symptoms (excessive daytime sleepiness, witnessed apnea, loud habitual snoring, and nocturnal choking), and OSA screening questionnaires. ENT and cardiac examination by a specialist was done.
Full-night attended polysomnography was performed on full night.

Results
The median apnea–hypopnea index in the studied group was 10.8 (range, 0.4–69.4). There were 21 (42.0%) non-OSA patients, while there were 29 (58%) OSA patients. There were eight (27.6%) mild OSA patients. Moderate OSA patients were 10 (34.5%). Severe OSA patients were 11 (37.9%). Median of the frequency of AF episodes in the last 1 year was significantly higher in the OSA group than in the normal group (P=0.01). No significant difference was present between both groups as regards the number of nocturnal arrhythmias not related to respiratory events. The frequency of paroxysmal AF episodes during the last year shows a significant positive correlation with severity of OSA, desaturation index, and total arousal index.

Conclusion
The results of our study support our hypothesis that OSA is a risk factor for AF. We should investigate patients with lone AF for the possibility of OSA.
