Published: May 2023

The coronavirus disease of 2019 (COVID-19) pandemic, directly and indirectly, affected the emergency medical care system and resulted in worse out-of-hospital cardiac arrest (OHCA) outcomes and epidemiological features compared with those before the pandemic. This review compares the regional and temporal features of OHCA prognosis and epidemiological characteristics. Various databases were searched to compare the OHCA outcomes and epidemiological characteristics during the COVID-19 pandemic with before the pandemic. During the COVID-19 pandemic, survival and favorable neurological outcome rates were significantly lower than before. Survival to hospitalization, return of spontaneous circulation, endotracheal intubation, and use of an automated external defibrillator (AED) decreased significantly, whereas the use of a supraglottic airway device, the incidence of cardiac arrest at home, and response time of emergency medical service (EMS) increased significantly. Bystander CPR, unwitnessed cardiac arrest, EMS transfer time, use of mechanical CPR, and in-hospital target temperature management did not differ significantly. A subgroup analysis of the studies that included only the first wave with those that included the subsequent waves revealed the overall outcomes in which the epidemiological features of OHCA exhibited similar patterns. No significant regional differences between the OHCA survival rates in Asia before and during the pandemic were observed, although other variables varied by region. The COVID-19 pandemic altered the epidemiologic characteristics, survival rates, and neurological prognosis of OHCA patients.Review registration: PROSPERO (CRD42022339435).

IntroductionOver the years, the most common methods for monitoring reproductive health in cattle have varied from transrectal palpation to B-mode ultrasonography. Nowadays, some portable ultrasound equipment includes the Doppler mode. Therefore, the aim of this study was to compare the accuracy of the different methods to assess corpus luteum (CL) functionality.MethodsIn Experiment 1, 53 Holstein lactating cows undergoing a synchronization protocol were examined via transrectal palpation and B-mode scanning. Measurements for the largest diameter (LAD) and subjective size of CL (SCLS) were collected. Data were analyzed using correlation analysis and ROC Curves. In Experiment 2, 30 Holstein non-lactating cows with a CL were administered PGF2α and examined several times after injection, first in B-mode and then with Power Doppler. Measurements for LAD, CL area (CLA) and subjective and objective CL blood flow were collected. Blood samples were taken in both experiments to determine P4 concentration. Data were analyzed using correlation analysis and the GLM repeated measures test.ResultsResults for Experiment 1 showed that LAD was more accurate than SCLS. In Experiment 2, CLA was the best measurement to assess CL function, although both subjective and objective CL blood flow offer accurate information 24 h after PGF2α administration.DiscussionConsequently, ultrasonography provides more accurate information about CL function than transrectal palpation. Although CLA seems to be an earlier indicator of luteal function than blood flow, 24 h after the onset of luteolysis, both parameters are valid.

Sachet water (SW) is a major source of drinking in most Nigerian homes, thus making it a possible conveyance medium for health risks due to contamination if persist rather than for replenishment of the body. This study collected SW from three busy neighborhoods in South-West Nigeria and investigated for the presence of indicator bacteria (Escherichia coli (E. coli), Total Coliform (TC), Total Heterophilic Bacteria (THB), Staphylococcus (Staph)) and some physio-chemical parameters (total dissolved solids (TDS), pH, electrical conductivity (EC), and salinity). Multi-variable and exploratory statistical methods were applied to the results to determine correlations between bacterial contamination levels and perceived brand reputation. Bacteriological tests with raw SW samples appeared too numerous to count (TNC) and thus required serial dilutions. After seven-fold serial dilutions, results obtained revealed that SW brands with good reputations had no TC and E. coli and was statistically significant with groupings of other SW brands (χ2 = 12.28; p < 0.05 and χ2 = 37.96; p < 0.05). Additionally, SW brands with poor reputations had mean values of TC (19.7×108 cfu/mL; 14×108 cfu/mL 1.15×108 cfu/mL) and E. coli (18.2×108 cfu/mL; 38.7×108 cfu/mL,32.4×108 cfu/mL) exceeding the threshold value of zero set by the World Health Organization (WHO). Only one sample from a poor reputation brand tested positive for Staphylococcus and was not statistically significant (χ2 = 5.2191; p = 0.074). Principal Component Analysis (PCA)/Factor Analysis (FA) revealed that most of the SW had fecal contamination was the major source. Therefore, this study suggests that periodic cleaning of distribution lines, location-specific treatment, and other quality control (QC) measures should be enforced to reduce water security risk for SW consumption in the region.

Relevance. The research is relevant because of a high prevalence of anterior and posterior crowding in children with mixed and permanent dentition (from 42 to 86 %), for whom the correction of the dentition form and the size is recommended by fixed expanding appliances with a screw. After the teenage growth spurt, the growth and development of jaws end, steady pathological signs form, there are psychological problems in a face and smile selfperception, and the question of the orthodontic treatment duration arises.Purpose. To study the effectiveness of treatment of patients with maxillary premolar area constriction during growth spurt using two modifications of fixed Hyrax expander.Material and methods. We examined 22 male patients aged 10.6 to 13 y.o. (average age 11.2 ± 1.6 years old) with permanent dentition, constriction of the posterior teeth and crowding of incisors, treated with a fixed expander (Hyrax appliance) in the upper jaw during the growth spurt. The patients formed two groups. Group 1 (n = 11) had the Hyrax screw at the level of the upper first premolars, and Group 2 (n = 11) had the Hyrax lock located at the first permanent molars. The patients activated the expander independently by ¼ turn every other day for six months. Then the appliance remained in the mouth for three months. We studied the maxillary expansion results on plaster models before and after six months of the expander fixation using the Tonn, Pont, Korkhaus, Bolton method.Results. The study has established that orthodontic correction of transversal abnormalities with a fixed Hyrax expander affects the maxillary posterior teeth expansion, changes their parameters and improves their movement. At the same time, in Group 1, the width between the first premolars and the first molars reached the norm calculated from the sum of the mesiodistal dimensions of the upper incisors, and in Group 2, the width between the first permanent molars exceeded the normal, and inter-first-premolar distance did not reach the normal values for three months of activation.Conclusion. Fixed Hyrax expander showed the best results if the screw was at the level of first premolars during the teenage growth spurt.

Published: May 2023

This Study aims at identifying the influence of using brainstorming strategy on the achievement of education specialized students in national education course at the Jordanian universities and their attitudes towards it. In order to achieve the goals of the study, achievement tests, which are consisted of (50) paragraphs, have been used. In addition to a questionnaire consists of (32) paragraphs distributed on three areas and applied on a sample of (266) female and male students who are selected by the accidental sampling method for a one academic semester. They are divided into two groups: The first is a control group consists of (130) female and male students taught traditionally during the academic year (2012-2013). Whereas, the second group is experimental that consists of (136) female and male students and is taught using the brainstorming strategy. Results showed that there is a statistically significant effect of using brainstorming strategy on student achievement and it shows a similar statistic significant to their attitudes towards it. However, the study shows that there are differences that are statistically significant attributed to gender variable and it is in the favor for males. It also shows a difference attributed to the academic year variable and it is in the favor for the third and fourth year students, in addition to the difference at the major study variable which is in the favor for the scientific specialties. While there is no statistically significant found among students’ attitudes that could be attributed to the variables of students’ gender, academic year and the major study. As the study also clarifies that there is a statistically significant strong positive association between students’ achievement and attitude. The study recommends developing students’ cognition by using brainstorming strategy in teaching the national education course through applying several activities.

Published: May 2023

<p> For electrolyzer applications, traditional solutions using line frequency transformers plus rectifiers are bulky, heavy and have low controllability. The Solid State Transformer (SST) could be a promising solution to solve the mentioned issues. This paper compares the semiconductor ratings and capacitance of five different Modular Multilevel Converter (MMC) based Solid State Transformer (SST) topologies. The results show that the DRU-MMC based topologies have the lowest semiconductor ratings and capacitance. Because of the unidirectional power flow requirement, the source side MMC of Back-to-Back (BtB) MMC based SST could be replaced by DRU, thus the cost is drastically saved. Another interesting finding is that the DRU-MMC energy ripple is much lower than half of the energy ripple in BtB MMC, which is different from HVDC MMC. </p>
A Ratioed Driver Based True Full-Duplex Interconnect with On-Chip Background Calibration

Published: May 2023

<p>In this paper, we propose a true full-duplex cell for space-constrained high-speed interconnects. The proposed interconnect can replace conventional simplex interconnects due to its ability to double the data rate with ease in PCB floor planning. The proposed ratioed driver-based self-interference (SI) cancellation technique uses an automatically adjustable on-chip background calibration which minimizes SI, to retrieve the far-end signal faithfully. The techniques used in the design relax linearity requirements and reduce power consumption for the transceiver. The SI cancellation is independent of the modulation format of the incoming signal from the far-end transmitter. Using the proposed technique reliable communication is possible between near-end and far-end transceivers without any synchronization. The proof-of-concept circuit has been designed and verified in a low-leakage 65 nm CMOS technology. The full-duplex nature of the transceiver can significantly reduce cross-talk in high-density interconnects compared to its simplex counterparts for the same throughput due to less stringent spacing requirements. </p>

Published: May 2023

Introduction: Developments in dental materials, CAD/CAM technologies and adhesive dentistry have improved the application of conservative restorations such as endocrowns and onlays. Among ceramics, zirconia has properties such as high strength, transformation toughening, chemical and structural durability, and biocompatibility, which enable zirconia to be used in the posterior area.
Aim: This study is a comparative evaluation of fracture resistance and failure modes in endodontically treated molars restored with zirconia endocrown and onlays.
Materials and methods: This study was performed on 20 human mandibular first molars with similar dimensions. After root canal treatment, the samples were divided into two groups: endocrowns and onlays (n=10). Restorations were made using a CAD-CAM milling machine with zirconia CAD blocks and, after cementation, subjected to 10,000 thermocycling and 500,000 fatigue cycle procedures, respectively. Each specimen was placed on a Universal Testing Machine and subjected to axial compressive force applied at a crosshead speed of 0.5 mm/min. The mean loads of failure of each group were statistically compared using the Student t-test. Chi-square tests were used to compare frequencies of failure modes among groups.
Results: Fracture resistance showed a statistically significant difference between endocrown (5374.6810&plusmn;670.03445 N) and onlay (3312.5000&plusmn;804.01428 N) (p<0.001). No statistically significant difference was detected in the distribution of failure types among the groups (p>0.05).
Conclusions: The fracture resistance of endocrown is substantially higher than that of onlay, and failure type does not differ in both restorations. Zirconia is a reliable material to use in conservative restorations.

Lung cancer is a leading cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) is a predominant subtype and treatment may include immunotherapy, radiotherapy, chemotherapy, and surgery. Tumors of bigger size infiltrating large bronchi and vessels require more invasive resection such as pneumonectomy. To save lung parenchyma, sleeve lobectomy can be performed in certain patients.
We report the case of a patient with NSCLC infiltrating the chest wall who underwent arterial sleeve lobectomy with rib resection. Furthermore, we discuss other surgical treatment strategies.
A 58-year-old female patient was admitted to the hospital in 2020 with pain in her left posterolateral chest. Radiological imaging revealed a tumor (5.0&times;3.5&times;4.8&nbsp;cm) in the top of the left lung, infiltrating pulmonary artery and ribs. Therefore, left upper sleeve lobectomy together with resection of rib blocks II to V was performed. The surgery was uncomplicated, but a few weeks postoperatively, the patient experienced repeated episodes of consciousness disturbances. Contrast CT revealed a cerebral malformation in the patient who died 3.5 months after surgery.
Sleeve lobectomy can be safely performed in patients with lung tumors infiltrating larger bronchi and vessels who would not tolerate pneumonectomy.

Le droit au séjour pour raisons médicales, comme les dispositions qui protègent les mineurs étrangers isolés, induisent une « biopolitique » de contrôle des flux migratoires. Dans ces affaires où il est question de contrôle des corps, le contentieux administratif révèle une propension des juges, lorsqu’il s’agit des personnes étrangères, à exercer directement leur « biopouvoir » en effectuant leur propre évaluation médicale, sans être éclairés par une expertise.
Compassion Fatigue Education: What Is Available Online for Nurses? A Consumer Website Review
Authors: Yee Angela 
Published: May 2023

Background:
Nurses have been identified as the most vulnerable health care profession to experience compassion fatigue. Currently, not much is known about the availability and credibility of online compassion fatigue resources for nurses. This systematic review of consumer websites explores the prevalence and quality of compassion fatigue educational resources available online to nurses.

Method:

A descriptive, cross-sectional, nonexperimental design was used. Findings were collected from the websites of the top 20 hospitals in the United States, all professional nursing organizations in the United States, and the top three most used social media platforms. Web-sites were evaluated for quality using the
Journal of the American Medical Association
(
JAMA
) benchmarks and Health on the Net Foundation certification.

Results:
A total of 143 websites were evaluated. Of these, three websites were identified as having the most credible, comprehensive educational resources on compassion fatigue.

Conclusion:

There is a need for more hospitals, professional nursing organizations, and social media websites to provide high-quality compassion fatigue educational resources for nurses.

Pobreza energética y vivienda: una perspectiva de justicia social
Authors: Tirado-Herrero Sergio 
Published: May 2023

El acceso equitativo a la energía y a la vivienda es una preocupación básica de la justicia social. A pesar de los numerosos vínculos entre estos dos bienes esenciales, los marcos teóricos de la justicia y la pobreza energética se han referido casi exclusivamente a la cuestión de la vivienda en términos de la eficiencia energética de los edificios residenciales. En respuesta a esta carencia conceptual, se propone la reintegración del factor vivienda en el marco de la justicia y pobreza energética a lo largo de los siguientes tres ejes: dimensiones materiales y temporales; dimensiones políticas; y dimensiones éticas y legales. Como ejemplo empírico de la importancia del nexo vivienda-energía en la práctica de la justicia social, se presenta el caso de dos movimientos sociales surgidos en Barcelona que trabajan con una perspectiva conjunta de derecho a la vivienda y a la energía: la Plataforma de Afectados por la Hipoteca (PAH) y la Aliança contra la Pobresa Energètica (APE). El artículo subraya la importancia de la vivienda y la energía como fundamentos materiales de una vida digna y su naturaleza conflictiva como necesidades esenciales y bienes de mercado.
L’Europe constitutionnelle : une ou divisée ?
Authors: Nussberger Angelika 
Published: May 2023

Le 24 février 2022, la Russie envahissait l’Ukraine, pays géographiquement et historiquement ancré à l’est du continent, mais qui proclama son indépendance du bloc soviétique en 1991 et se rapprocha peu à peu de l’Europe de l’Ouest. C’est dans le contexte brûlant des prémices de cette guerre qu’Angelika Nussberger a prononcé les quatre conférences qui composent ce livre. Au regard de la réception des idées des Lumières, des espoirs de construction d’une « maison commune européenne » (Mikhaïl Gorbatchev) et de la phase de désillusion après 2000, elle explore l’histoire de l’Europe sous l’angle du droit, montre en quoi la diversité non seulement des héritages juridiques – notamment constitutionnels – mais aussi des positions idéologiques peut représenter un obstacle à l’unité de l’Europe, et trace des voies possibles pour un avenir commun.

Alors que le conflit russo-ukrainien cristallise aujourd’hui le clivage Est-Ouest, cet ouvrage éclaire l’actualité en analysant les divergences sur les valeurs fondamentales, à savoir la démocratie, les droits de l’homme et l’État de droit, qui fragilisent les relations entre l’Europe orientale et l’Europe occidentale depuis leur rencontre durant la décennie qui suivit la chute du mur de Berlin.
