Migrant mothers’ experiences of Caesarean section: a transcultural qualitative study
Authors: Rodriguez Juliette , Moro Marie Rose , Radjack Rahmeth 
Published: April 2023

ObjectivesMigrant women face an increased risk of adverse obstetrical outcome and Caesarean section. The psychological experience of Caesarean section combines physiological, social, and cultural dimensions. This qualitative study explores the subjective experiences of first-generation migrant women who gave birth by Caesarean section.MethodsSeven qualitative, semi-directed interviews were conducted from January to March 2022 in a Paris maternity hospital, with women in their postpartum period who had had a scheduled or emergency Caesarean section and straightforward obstetrical outcomes. The presence of an interpreter-mediator was systematically offered. Thematic analysis of the interviews was carried out following the Interpretative Phenomenological Analysis (IPA) methodology.ResultsFour themes were identified in the thematic analysis relating to the women’s experiences of Caesarean section: (1) The shock of the intervention combines disappointment, fear and early separation from the baby, (2) Pregnancy and delivery far from one’s family aggravates the psychological suffering caused by isolation and loneliness related to migration, (3) The lack of cultural representations of Caesarean section leads to negative preconceptions and hinders mental preparation, in contrast with traditional or medicalised childbirth, and (4) The women’s experiences of the medical follow-up highlights the importance of the continuity of care.Discussion and conclusionCaesarean section, which is a physical break, re-enacts the symbolic break (cultural, social, familial) that follows on from emigration. Improvements in care include the need for a better preparation for Caesarean section, active efforts for care continuity, and the development of early prevention interviews and groups in maternity units.

IntroductionRobot-assisted thoracoscopic surgery (RATS) is an alternative to video-assessed thoracoscopic surgery (VATS) for the treatment of lung cancer but concern exists regarding the high associated costs. The COVID-19 pandemic added further financial pressure to healthcare systems. This study investigated the impact of the learning curve on the cost-effectiveness of RATS lung resection and the financial impact of the COVID-19 pandemic on a RATS program.MethodsPatients undergoing RATS lung resection between January 2017 and December 2020 were prospectively followed. A matched cohort of VATS cases were analyzed in parallel. The first 100 and most recent 100 RATS cases performed at our institution were compared to assess the learning curve. Cases performed before and after March 2020 were compared to assess the impact of the COVID-19 pandemic. A comprehensive cost analysis of multiple theatre and postoperative data points was performed using Stata statistics package (v14.2).Results365 RATS cases were included. Median cost per procedure was £7,167 and theatre cost accounted for 70%. Major contributing factors to overall cost were operative time and postoperative length of stay. Cost per case was £640 less after passing the learning curve (p &lt; 0.001) largely due to reduced operative time. Comparison of a post-learning curve RATS subgroup matched to 101 VATS cases revealed no significant difference in theatre costs between the two techniques. Overall cost of RATS lung resections performed before and during the COVID-19 pandemic were not significantly different. However, theatre costs were significantly cheaper (£620/case; p &lt; 0.001) and postoperative costs were significantly more expensive (£1,221/case; p = 0.018) during the pandemic.DiscussionPassing the learning curve is associated with a significant reduction in the theatre costs associated with RATS lung resection and is comparable with the cost of VATS. This study may underestimate the true cost benefit of passing the learning curve due to the effect of the COVID-19 pandemic on theatre costs. The COVID-19 pandemic made RATS lung resection more expensive due to prolonged hospital stay and increased readmission rate. The present study offers some evidence that the initial increased costs associated with RATS lung resection may be gradually offset as a program progresses.

Sulfated glycans from marine organisms are excellent sources of naturally occurring glycosaminoglycan (GAG) mimetics that demonstrate therapeutic activities, such as antiviral/microbial infection, anticoagulant, anticancer, and anti-inflammation activities. Many viruses use the heparan sulfate (HS) GAG on the surface of host cells as co-receptors for attachment and initiating cell entry. Therefore, virion–HS interactions have been targeted to develop broad-spectrum antiviral therapeutics. Here we report the potential anti-monkeypox virus (MPXV) activities of eight defined marine sulfated glycans, three fucosylated chondroitin sulfates, and three sulfated fucans extracted from the sea cucumber species Isostichopus badionotus, Holothuria floridana, and Pentacta pygmaea, and the sea urchin Lytechinus variegatus, as well as two chemically desulfated derivatives. The inhibitions of these marine sulfated glycans on MPXV A29 and A35 protein–heparin interactions were evaluated using surface plasmon resonance (SPR). These results demonstrated that the viral surface proteins of MPXV A29 and A35 bound to heparin, which is a highly sulfated HS, and sulfated glycans from sea cucumbers showed strong inhibition of MPXV A29 and A35 interactions. The study of molecular interactions between viral proteins and host cell GAGs is important in developing therapeutics for the prevention and treatment of MPXV.

BackgroundIn Finland, there have been various strategies attempting to provide access to GPs. The 'restricted-List General Practitioner model' (rLGP) was launched in primary health care (PHC) in the city of Vantaa after the 'named General Practitioner model' (nGP) failed to provide sufficient access to GPs. This was done to improve access to GP appointments for those most needing care.AimTo evaluate the impact of the transition from nGP to rLGP on access to non-urgent scheduled appointments among patients aged ≥75 years.Design & settingA register-based follow-up study in public PHC in Vantaa, Finland.MethodThe study focused on patients aged ≥75 years who used PHC from 2004–2008. It looked at the number of non-urgent and urgent scheduled appointments, patient contacts, home visits, PHC emergency department appointments, and cancelled appointments, which were recorded 7 years before and after the transition from nGP to rLGP in 2011 and adjusted to patient-years. Non-urgent appointments were booked to the patient’s own nGP or rLGP in public PHC, whereas urgent appointments could be to any GP.ResultsThe number of non-urgent scheduled appointments to GPs was halved during the time of nGP, before launching the rLGP. Simultaneously, the number of urgent scheduled appointments more than tripled. The number of both started to plateau a year before the rLGP was launched. The number of both non-urgent and urgent scheduled appointments remained mainly at that level after rLGP was implemented.ConclusionThe rLGP model was unsuccessful in improving access to non-urgent scheduled appointments to GPs.

<p>Education is a humanitarian right. The alarming increase in armed conflict, forceful displacements, health, and climatic disasters, along with other crises dramatically impact the education system in long term. Pervasive computing technology can provide a smooth interaction to support education during a crisis. The paper, therefore, aims to discuss the support that pervasive computing technologies can provide during a crisis for the Least Developed Countries like Bangladesh with the least possible cost. The paper highlights different real-life cases in Bangladesh and then uses secondary data from 2006 to 2020 to understand the relation at the times when education was hampered for the adverse situation. Based on the findings the importance of the application of pervasive computing and necessary recommendations are given which may help the state and locals in responsibility to support education at such times.</p>
Simplifying the implementation of machine safety on LVMCCs
Authors: Marques Roberto , Rivera Gabriel , Newbern James , Johnson Jonathan B 
Published: April 2023

<p>When parts of a machinery control system are required for risk reduction of a hazard, they are considered a safety function. A typical safety function is comprised of safety input and output devices which are monitored and controlled by a safety logic device. Emergency stop buttons and guard door interlocks are typical safety input devices which are often remote, and field wired. Safety relays are typical safety logic devices and safety contactors, and variable frequency drives (VFDs) are typical output devices which are commonly located inside of a Low Voltage Motor Control Center (LVMCC). Safety functions must be engineered and implemented according to relevant machinery safety standards. Despite having common design requirements, safety functions often require customized engineering when applied to a LVMCC. </p>
<p>This paper serves as an overview of how to promote standardization in the implementation of safety functions when using LVMCC’s. Standardization reduces delivery times of safety rated LVMCC units, decreases overall cost of acquisition of a safety rated LVMCC, and enables users to maximize operational productivity while assuring a proper design of the safety function.</p>
<p>The selection of standard safety rated motor controller units as safety function subsystems enables users to minimize personal and enterprise risk when engineering new safety functions.</p>

Abstract: This is a cross-sectional study was conducted in Al-Kufa city/ Al-najaf Al-Ashraff province to determine the prevalence of pityriasis alba in the children of primary school.
Objective: This study aims to determine the prevalence of Pityriasis alba in the children of primary schools.
Methodology: The setting of study: The study was conducted in Al-Kufa city /Al-Najaf Al-Ashraf province.
Data collection : During the period of 1/4/2011 to 31\4\2012.
The study sample: The total number of primary school submitted was 38 and the number of total pupil were 18356, and founded the number of infected pupil with pityriasis alba was 1935 with percentage (10.54%), number of male was 1067 (55.14%) and number of female was 868 (44.86%).
Data analysis: The data was analyzed through the application of descriptive statistical analysis that include (Chi-square), and application of inferential statistical analysis that include (chi-square, P value) .
Results: The results of this study showed that the prevalence of pityriasis alba in the male is more than in the female, the more exposed infected age group was between (6-8 year). The white patches were more clear in dark color, appearance of patches in the face was more clear than other parts of the body. The number of pupil who suffered of anemia was 232 (12%), and 242 (12.5%) suffered of infected with Oxyuris vermicular is, Giardia lamblia, Entamoeba histolytic and other parasites.
Conclusion: We conclude in this study that the prevalence of pityriasis alba was acceptable in comparison with other similar studies in many countries, this may reflect some negligence, poor personal hygiene and nutrition in primary schoolchildren, care health provided was inadequate.
Recommendation: Based on the above results, this study recommended that the primary health care sector must examine the children in beginning of study. Periodic skin examination is of a high value. Health education for teachers and parents on sound personal hygiene and clean environment are recommended.
La universidad reformista versus la universidad nacional y popular.
Authors: Carli Sandra 
Published: April 2023

Este artículo aborda algunos de los debates sobre la reforma de la universidad en la Argentina que se produjeron en los años cincuenta y sesenta del siglo XX, vinculados con la transición de la universidad de élite a la universidad masiva y el despliegue del modelo universitario latinoamericano, en un período de recurrencia de golpes Militares y de conflictividad política, en el que se destaca la activa participación del movimiento estudiantil. Analiza los itinerarios académicos y políticos y los escritos de Risieri Frondizi, profesor de Filosofía, quien fuera rector de la Universidad de Buenos Aires (UBA) entre 1957 y 1962 y un exponente de la renovación de la tradición reformista; y de Juan José Hernández Arregui, también filósofo, expulsado de sus cargos universitarios y que se constituirá en un intelectual orgánico del peronismo proscripto y portavoz de la emergencia del pensamiento nacional y popular sobre la universidad, que se plasmará en la breve experiencia de la Universidad del 73.
Geopolitics, History, International Relations and Re-Crafting TPLF Secession in Ethiopia and Destabilization in the Horn of Africa

Published: April 2023

The word terrorism means the deliberate creation and exploitation of fear for bringing about political change. All terrorist acts involve violence or—equally important—the threat of violence. The form of violence takes place on the name of language, tribal group ethnicity and religion. TPLF is one of the examples in North East Africa and in Horn consistently believe in violence on the pretext of one or the other mentioned above. The history explains that the violence cannot be justify today on the name of EPRDF movement/Marxist dominance or CIA supported antiterrorist/Capitalist ideology connecting international links. Further, the violence with the international weapon system doesn’t misnomer with international solidarity. The current crisis in Ethiopia ultimately is the geopolitical gluttony of lust for power, American pang of hunger of absolute control on oil and mineral resources on the name of terrorism and TPLF excitement of re-crafting ideology for the Tigre empire and future its secession as Tigre independent State. The ultimate loss to the Horn of Africa destabilization, which is fighting against all odds of natural calamity and weapon movement in this region.

Abstract
Further discoveries and detailed studies of close binaries of intermediate-mass stars in hierarchical triple systems are needed in order to understand their formation. Here we report the discovery of a 0.82M
⊙ companion to the intermediate mass spectroscopic binary HIP 67199 at a projected separation of 150 mas ↔ 15 au based on a VLTI/GRAVITY observation. In addition, the spectroscopic binary was spatially resolved with a projected separation 1.70 mas ↔ 0.18 au and inferred masses 1.84M
⊙ + 1.72M
⊙. Further observations can determine the amplitude of eccentricity oscillations in the inner system induced by the third star. HIP 67199 is a potential progenitor for a double white dwarf hiding within the glow of a main-sequence companion.
Sodium Brightening of (3200) Phaethon near Perihelion
Authors: Zhang Qicheng , Battams Karl , Ye 叶 Quanzhi 泉志 , Knight Matthew M. , Schmidt Carl A. 
Published: April 2023

Abstract
Sunskirting asteroid (3200) Phaethon has been repeatedly observed in Solar Terrestrial Relations Observatory (STEREO) Heliospheric Imager 1 (HI1) imagery to anomalously brighten and produce an antisunward tail for a few days near each perihelion passage, phenomena previously attributed to the ejection of micron-sized dust grains. Color imaging by the Solar and Heliospheric Observatory (SOHO) Large Angle Spectrometric Coronagraph (LASCO) during the 2022 May apparition indicates that the observed brightening and tail development instead capture the release of sodium atoms, which resonantly fluoresce at the 589.0/589.6 nm D lines. While HI1's design bandpass nominally excludes the D lines, filter degradation has substantially increased its D line sensitivity, as quantified by the brightness of Mercury’s sodium tail in HI1 imagery. Furthermore, the expected fluorescence efficiency and acceleration of sodium atoms under solar radiation readily reproduce both the photometric and morphological behaviors observed by LASCO and HI1 during the 2022 apparition and the 17 earlier apparitions since 1997. This finding connects Phaethon to the broader population of sunskirting and sungrazing comets observed by SOHO, which often also exhibit bright sodium emission with minimal visible dust, but distinguishes it from other sunskirting asteroids without detectable sodium production under comparable solar heating. These differences may reflect variations in the degree of sodium depletion of near-surface material and thus the extent and/or timing of any past or present resurfacing activity.

Authors: Perera W. P. G. L. , Suraweera S. A. D. H. N. 
Published: April 2023

During the crisis time, teaching and learning activities were carried out remotely using digital teaching and learning apps/devices. In online learning, it is essential to identify the need to respond on time. Libraries are the primary provider of information resources/services to the academic community. In Sri Lankan academia, the time to adopt technologies has become mandatory due to safety concerns and the COVID-19 situation. In this research, one state university was chosen as a case study, and academic staff, students, and library staff were considered as the population. A stratified random sampling method was used to conduct the study. The data collection is done through the questionnaire. The primary framework was modified based on suggestions identified through data analysis. This study aimed to seek the current situation of the e-learning support of the University libraries and to identify other service opportunities in an e-learning environment. Research gaps and factors were identified because of the review process and findings. The findings were identified through major areas, such as e-learning, resources, learning services, ICT infrastructure facilities, Information professionals' roles, and skills and management policies. Library services can proactively organize according to user requirements. For this, library pre-planning is greatly important. The conceptual model presented in this paper was developed based on gaps identified through reviewing existing literature, research results, and user suggestions. Libraries that are conducting user surveys could consider the factors presented in this model.

Authors: Nafary Amirhossen , Mousavi Nezhad Seyed Amin , Jalili Shirin 
Published: April 2023

Background:
Chitin and chitosan are utilized in many industries such as pharmacy, biotechnology, and medicine. The mealworm beetle, Tenebrio Molitor, is simply breaded and does not require a vast production space.

Materials and Methods:
In this study, we extracted chitin and chitosan using two different methods from Tenebrio Molitor adult beetles. Then we studied their physical and chemical properties along with their antibacterial effect.

Results:
Using two new methods we extracted 13, 3%, and 17.7% chitin from the dry mealworm beetle which was higher than in previous studies. The chitosan yield of the extracted chitin was 78.26% and 76.43%, respectively. The observed FTIR peaks for chitin and chitosan in this study were in accordance with the characteristic peaks. The degree of acetylation of chitin was 95.09% and 92.55% and the degree of deacetylation was 75.84%, and 72.6% from the first and second methods, respectively. The extracted chitosan also showed an antibacterial effect against Pseudomonas aeruginosa.

Conclusions:
Our study demonstrated that chitin and chitosan extracted from adult mealworm beetles could be considered as a replacement for commercial chitosan and needs further studies.
Emerging Adults and the Use of Textual Digital Communication: A Reflection on Self-Esteem, Loneliness, Anxiety, and Wellbeing
Authors: Tamba Georgiana Ioana , Iancu Ioana 
Published: April 2023

Digital communication is a great facilitator of human connection, positively contributing to life satisfaction and prosocial behavior. However, the existing findings also insist on the drawbacks of the digital communication, as low levels of wellbeing satisfaction, or happiness. Thus, aiming to reconciliate the two sets of assumptions and relying on the reality that textual communication is preferred to voice interaction, the present paper investigates the impact of using messaging apps on the emotional state. More specifically, the study explores if time spent texting, the general affinity towards technology, the perceived ease of use, the perceived usefulness, and the intentional behavior to use messaging applications are correlated with self-esteem, loneliness, anxiety, and wellbeing. An online opinion survey (N=147) with Romanian emerging adults is conducted between February and May 2022. The results show that a positive attitude towards technology is negatively correlated with the feelings of loneliness and anxiety. Moreover, a positive perception on the ease of use and usefulness of the messaging applications is linked with an increased wellbeing.
