Unraveling the Dynamics of Omicron (BA.1, BA.2, and BA.5) Waves and Emergence of the Deltacron Variant: Genomic Epidemiology of the SARS-CoV-2 Epidemic in Cyprus (Oct 2021–Oct 2022)

Viruses (2023)

Andreas C. Chrysostomou Bram Vrancken Christos Haralambous Maria Eleni Alexandrou Ιωάννα Γρηγορίου

Commencing in December 2019 with the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), three years of the coronavirus disease 2019 (COVID-19) pandemic have transpired. The virus has consistently demonstrated a tendency for evolutionary adaptation, resulting in mutations that impact both immune evasion and transmissibility. This ongoing process has led to successive waves of infections. This study offers a comprehensive assessment spanning genetic, phylogenetic, phylodynamic, and phylogeographic dimensions, focused on the trajectory of the SARS-CoV-2 epidemic in Cyprus. Based on a dataset comprising 4700 viral genomic sequences obtained from affected individuals between October 2021 and October 2022, our analysis is presented. Over this timeframe, a total of 167 distinct lineages and sublineages emerged, including variants such as Delta and Omicron (1, 2, and 5). Notably, during the fifth wave of infections, Omicron subvariants 1 and 2 gained prominence, followed by the ascendancy of Omicron 5 in the subsequent sixth wave. Additionally, during the fifth wave (December 2021-January 2022), a unique set of Delta sequences with genetic mutations associated with Omicron variant 1, dubbed "Deltacron", was identified. The emergence of this phenomenon initially evoked skepticism, characterized by concerns primarily centered around contamination or coinfection as plausible etiological contributors. These hypotheses were predominantly disseminated through unsubstantiated assertions within the realms of social and mass media, lacking concurrent scientific evidence to validate their claims. Nevertheless, the exhaustive molecular analyses presented in this study have demonstrated that such occurrences would likely lead to a frameshift mutation-a genetic aberration conspicuously absent in our provided sequences. This substantiates the accuracy of our initial assertion while refuting contamination or coinfection as potential etiologies. Comparable observations on a global scale dispelled doubt, eventually leading to the recognition of Delta-Omicron variants by the scientific community and their subsequent monitoring by the World Health Organization (WHO). As our investigation delved deeper into the intricate dynamics of the SARS-CoV-2 epidemic in Cyprus, a discernible pattern emerged, highlighting the major role of international connections in shaping the virus's local trajectory. Notably, the United States and the United Kingdom were the central conduits governing the entry and exit of the virus to and from Cyprus. Moreover, notable migratory routes included nations such as Greece, South Korea, France, Germany, Brazil, Spain, Australia, Denmark, Sweden, and Italy. These empirical findings underscore that the spread of SARS-CoV-2 within Cyprus was markedly influenced by the influx of new, highly transmissible variants, triggering successive waves of infection. This investigation elucidates the emergence of new waves of infection subsequent to the advent of highly contagious and transmissible viral variants, notably characterized by an abundance of mutations localized within the spike protein. Notably, this discovery decisively contradicts the hitherto hypothesis of seasonal fluctuations in the virus's epidemiological dynamics. This study emphasizes the importance of meticulously examining molecular genetics alongside virus migration patterns within a specific region. Past experiences also emphasize the substantial evolutionary potential of viruses such as SARS-CoV-2, underscoring the need for sustained vigilance. However, as the pandemic's dynamics continue to evolve, a balanced approach between caution and resilience becomes paramount. This ethos encourages an approach founded on informed prudence and self-preservation, guided by public health authorities, rather than enduring apprehension. Such an approach empowers societies to adapt and progress, fostering a poised confidence rooted in well-founded adaptation.

Οι στάσεις των καθηγητών φυσικής αγωγής του νομού Αργολίδας απέναντι στους αλλοδαπούς μαθητές τους

Ιωάννα Γρηγορίου

The study examined the attitude of the teachers in Physical Education in Argolida toward their foreign students. 87 teachers in physical education have taken part in this survey, teachers who also work in elementary and high schools. The purpose of this study was to find if the teachers of the sample differentiate their behavior depending on the national or other identity. Two questionnaires were used to collect their answers. The first one refers to the attitude of the P.E. teachers regarding the motivation, the participation in the lesson and at the school games and competencies, and the performance of the foreign students they have in their classes, and all this comparatively with their estimations toward the native students. The second questionnaire is also a five point Lickert scale which measures the level of racism of adults. An interesting result is that there is no relation between the demographic data and the racist profile of this sample. It has been found that over half of the P.E. teachers of the sample support that the school life wouldn’t be as proper if their weren’t any foreign students (56%). Important were also the differences of means which were detected among the answers that concerned their local and foreign students. Another significant result is that there are exciting differences of means between the questions that concern the students that comes from Greece and the students that come from foreign countries. These raise further questions to be answered. Questions involving multicultural education and physical education as well.

Extensive Testing and Public Health Interventions for the Control of COVID-19 in the Republic of Cyprus between March and May 2020

Journal of Clinical Medicine (2020)

Annalisa Quattrocchi Ioannis Mamais Constantinos Tsioutis Eirini Christaki Costas S. Constantinou

Coronavirus disease 2019 (COVID-19) has significantly affected the well-being of individuals worldwide. We herein describe the epidemiology of COVID-19 in the Republic of Cyprus during the first epidemic wave (9 March–3 May 2020). We analyzed surveillance data from laboratory-confirmed cases, including targeted testing and population screening. Statistical analyses included logistic regression. During the surveillance period, 64,136 tests (7322.3 per 100,000) were performed, 873 COVID-19 cases were diagnosed, and 20 deaths were reported (2.3%). Health-care workers (HCWs) represented 21.4% of cases. Overall, 19.1% of cases received hospital care and 3.7% required admission to Intensive Care Units. Male sex (adjusted Odds Ratio (aOR): 3.04; 95% Confidence Interval (CI): 1.97–4.69), increasing age (aOR: 1.56; 95%CI: 1.36–1.79), symptoms at diagnosis (aOR: 6.05; 95%CI: 3.18–11.50), and underlying health conditions (aOR: 2.08; 95%CI: 1.31–3.31) were associated with hospitalization. For recovered cases, the median time from first to last second negative test was 21 days. Overall, 119 primary cases reported 616 close contacts, yielding a pooled secondary attack rate of 12% (95%CI: 9.6–14.8%). Three population-based screening projects, and two projects targeting employees and HCWs, involving 25,496 people, revealed 60 positive individuals (0.2%). Early implementation of interventions with targeted and expanded testing facilitated prompt outbreak control on the island.

This research project aims to explore the psychological aspects which make working conditions more satisfactory for PE teachers in the prefectures of Argolida, Arcadia and Laconia. It also tries to show the relationship between comfortable working conditions and the teachers’ competency in the performance of their tasks. The PE teachers who participated in this research consider their work worthwhile and important. On the other hand they have got some doubts if the department they work for takes care of them. They are not paid as much as deserve, which causes financial insecurity. Besides their opportunities for promotion are few, no matter how experienced they are. They agree that the head of their department supports them whenever they ask for it but they doubt if their problems are really understood. PE teachers who belong to the secondary school education and complete their working hours at the elementary school education are more satisfied with their profession. PE teachers under the age of 35 are less satisfied with their working conditions. PE teachers with a second academic degree are less satisfied as far as ESI (Opportunities and working conditions). It seems that the educational level of the parents influences the way PE teachers approach promotion perspectives. Salary and working conditions. PE teachers who work at the elementary school education show higher rates of educational competency. PE teachers whose parents have finished high school show higher rates of educational competency than the ones whose parents have got a university degree. Additional studies don’t seem to influence their educational competency.

Leadership and Intention to Leave Among Public Health Sector Physicians in Cyprus: A National Cross-Sectional Study

Studies in health technology and informatics (2023)

Ιωάννα Γρηγορίου Eleftheria C. Economidou Demetris Avraam Elpidoforos S. Soteriades Evridiki Papastavrou

Physician shortage is a major concern in many health care systems globally, while healthcare leadership constitutes one of the most vital factors within human resource management. Our study examined the relationship between managers' leadership styles and physicians' intent to leave their current position. In this cross-sectional national survey, questionnaires were distributed to all physicians working in the public health sector of Cyprus. Most demographic characteristics evaluated by chi-square or Mann-Whitney test, were statistically significantly different between those who intended to leave their job and those who did not. The results of our study demonstrated that transformational leadership has a positive influence on retention of physicians in public hospitals, while non leadership infers a negative influence. Developing leadership skills in physician supervisors is of a great importance for organizations to make a large impact on health professionals' retention and overall performance.

Organisational commitment, job satisfaction and intention to leave among physicians in the public health sector of Cyprus: a cross-sectional survey

BMJ Open (2023)

Ιωάννα Γρηγορίου Evridiki Papastavrou Andreas Charalambous Eleftheria C. Economidou Elpidoforos S. Soteriades

Objectives Organisational commitment, job satisfaction and intention to leave constitute important characteristics of health professionals’ employment status. Our study aimed at investigating the level of organisational commitment, job satisfaction in association with intention to leave among physicians. Design A cross-sectional study. Setting A survey was conducted using self-administered questionnaires (the Organizational Commitment Questionnaire and the Job Satisfaction Survey) among all physicians working in the public health sector of Cyprus (October 2016–January 2017). Participants Out of 690 physicians working in the public health sector who received an invitation to participate, 511 completed the survey and 9 were excluded. Therefore, 502 physicians were included in the final analysis (response rate 73%). A total of 188 cases were excluded because they were undetermined with respect to their intention to leave and a total of 75 cases were excluded from the regression analysis due to missing values on at least one variable or due to having values considered as outliers. Therefore, a total of 239 physicians (120 men and 119 women) were included in the current analysis. Primary and secondary outcome measures Physicians’ intention to leave. Results A considerably large percentage of physicians (72.8%) working in the public hospitals and healthcare centres of Cyprus reported their intention to leave their job. Moreover, the majority of employees in public hospitals (78.4%) intended to leave their job, while only 21.6% of employees in health centres reported an intention to leave (p<0.001). The study also confirmed that organisational commitment and job satisfaction were negatively correlated with intention to leave. In addition, the results of this study demonstrate that certain demographics also influence physicians’ intention to leave including age, gender and medical specialisation. Conclusions Certain physicians’ demographics, organisational commitment and job satisfaction constitute important parameters influencing physicians’ intention to leave their job.
