- PublicationBurnout and motivation to study medicine among students during the COVID-19 pandemic(Frontiers Media SA, 2023)
; ; ; ;Clio Metakides ;Lena Pielemeier ;Dimitrios G. Mytilinaios ;Chryso Pieridi ;Elizabeth O. Johnson ;Dimitrios NtourakisIlias P. NikasAim: To investigate medical students’ burnout and motivation levels in each of the six years of their studies during the COVID-19 pandemic and identify independent predictors of burnout and motivation. Methods: An anonymous cross-sectional survey was sent to the students of all six years within our school. Burnout was measured with the adapted Oldenburg Burnout Inventory questionnaire (OLBI-S) and motivation with the updated Strength of Motivation for Medical School (SMMS-R) questionnaire. Univariate analysis was performed with the Kruskal–Wallis test and Spearman’s correlation, while multivariable analysis with linear regression models. Results: A total of 333 medical students (52% of student body) responded. Higher burnout levels correlated with lower motivation to study medicine (rho = −0.30, p < 0.001). Burnout levels differed between the six years of medical studies, peaking in years two and four whereas being the lowest in year one (p = 0.01). Motivation levels differed significantly as well, peaking in years one and four whereas being the lowest in years five and six (p = 0.012). In the multivariable linear regression models, being a female (b = 2.22, p = 0.016), studying in the fourth year vs. first year (b = 2.54, p = 0.049), having a perceived beginner/intermediate vs. advanced/expert technology level (b = 2.05, p = 0.032) and a perceived poor school support system (b = 6.35, p < 0.001) were independently associated with higher burnout levels. Furthermore, studying in the fifth year vs. first year (b = −5.17, p = 0.019) and a perceived poor school support system (b = −3.09, p = 0.01) were independently associated with a reduced motivation to study medicine. Conclusion: Our study highlighted potential areas for intervention to decrease the rate of burnout and low motivation among medical students. However, further research is needed to unravel the full effect of the pandemic on medical students. - PublicationThe impact of seasonal influenza vaccination uptake on COVID-19 vaccination attitudes in a rural area in Greece(Elsevier Ltd, 2023)
; ; ;Andria Papazachariou ;Onoufrios Malikides ;Maria Stamatelatou ;Nektaria Vasilaki ;Athanasia Milioni ;Maria DasenakiNikolaos SpernovasilisIntroduction: Promoting vaccination for coronavirus disease 2019 (COVID-19), especially for high-risk groups such as the elderly and persons with comorbidities, is important for reducing the incidence of severe disease and death. Methods: Retrospective cross-sectional study of factors associated with COVID-19 vaccination, including previous influenza vaccination, among all persons who received medical services in a rural area in Crete, Greece, between October 2020-May 2021. Results: Among 3129 participants, receipt of influenza vaccination in 2020–21 was strongly associated with COVID-19 vaccination, as was influenza vaccination in 2019–20, albeit to a lesser extent. In addition, persons older than 59 years (with exception of those 90 + years old) and those who lived closer to the hospital/health center, were more likely to vaccinate for COVID-19. Persons younger than 40 years of age, females, persons with mental illness or neurologic disease, were also less likely to vaccinate for COVID-19 (all p < 0.001). Conclusions: COVID-19 vaccination was more likely among those who were vaccinated for influenza before and during the pandemic. Access to healthcare services and specific comorbidities, were important influencers for vaccination, underlying the importance of tailored interventions to enforce vaccination in high-risk groups. - PublicationLomentospora prolificans Disseminated Infections: A Systematic Review of Reported Cases(MDPI, 2023-01)
; ;Afroditi Konsoula ;Aris P. Agouridis ;Lamprini MarkakiNikolaos SpernovasilisBackground: Lomentospora prolificans, a rare, highly virulent filamentous fungus with high rates of intrinsic resistance to antifungals, has been associated with different types of infections in immunocompromised as well as immunocompetent individuals. Objective: To systematically address all relevant evidence regarding L. prolificans disseminated infections in the literature. Methods: We searched Medline via PubMed and Scopus databases through July 2022. We performed a qualitative synthesis of published articles reporting disseminated infections from L. prolificans in humans. Results: A total of 87 studies describing 142 cases were included in our systematic review. The pathogen was most frequently reported in disseminated infections in Spain (n = 47), Australia (n = 33), the USA (n = 21), and Germany (n = 10). Among 142 reported cases, 48.5% were males. Underlying conditions identified for the majority of patients included malignancy (72.5%), hemopoietic stem cell transplantation (23.2%), solid organ transplantation (16%), and AIDS (2%). Lungs, central nervous system, skin, eyes, heart and bones/joints were the most commonly affected organs. Neutropenia was recorded in 52% of patients. The mortality rate was as high as 87.3%. Conclusions: To the best of our knowledge, this is the first systematic review conducted on disseminated infections due to this rare microorganism. Physicians should be aware that L. prolificans can cause a diversity of infections with high mortality and primarily affects immunocompromised and neutropenic patients. - PublicationESCMID/EUCIC clinical practice guidelines on perioperative antibiotic prophylaxis in patients colonized by multidrug-resistant Gram-negative bacteria before surgery(Elsevier B.V., 2023-04)
; ;Elda Righi ;Nico T. Mutters ;Xavier Guirao ;Maria Dolores del Toro ;Christian Eckmann ;Alex W. Friedrich ;Maddalena Giannella ;Jan Kluytmans ;Elisabeth Presterl ;Eirini Christaki ;Elizabeth L.A. Cross ;Alessandro Visentin ;Gabriele SgangaEvelina TacconelliScope: The aim of the guidelines is to provide recommendations on perioperative antibiotic prophylaxis (PAP) in adult inpatients who are carriers of multidrug-resistant Gram-negative bacteria (MDR-GNB) before surgery. Methods: These evidence-based guidelines were developed after a systematic review of published studies on PAP targeting the following MDR-GNB: extended-spectrum cephalosporin-resistant Enterobacterales, carbapenem-resistant Enterobacterales (CRE), aminoglycoside-resistant Enterobacterales, fluoroquinolone-resistant Enterobacterales, cotrimoxazole-resistant Stenotrophomonas maltophilia, carbapenem-resistant Acinetobacter baumannii (CRAB), extremely drug-resistant Pseudomonas aeruginosa, colistin-resistant Gram-negative bacteria, and pan-drug-resistant Gram-negative bacteria. The critical outcomes were the occurrence of surgical site infections (SSIs) caused by any bacteria and/or by the colonizing MDR-GNB, and SSI-attributable mortality. Important outcomes included the occurrence of any type of postsurgical infectious complication, all-cause mortality, and adverse events of PAP, including development of resistance to targeted (culture-based) PAP after surgery and incidence of Clostridioides difficile infections. The last search of all databases was performed until April 30, 2022. The level of evidence and strength of each recommendation were defined according to the Grading of Recommendations Assessment, Development and Evaluation approach. Consensus of a multidisciplinary expert panel was reached for the final list of recommendations. Antimicrobial stewardship considerations were included in the recommendation development. Recommendations: The guideline panel reviewed the evidence, per bacteria, of the risk of SSIs in patients colonized with MDR-GNB before surgery and critically appraised the existing studies. Significant knowledge gaps were identified, and most questions were addressed by observational studies. Moderate to high risk of bias was identified in the retrieved studies, and the majority of the recommendations were supported by low level of evidence. The panel conditionally recommends rectal screening and targeted PAP for fluoroquinolone-resistant Enterobacterales before transrectal ultrasound-guided prostate biopsy and for extended-spectrum cephalosporin-resistant Enterobacterales in patients undergoing colorectal surgery and solid organ transplantation. Screening for CRE and CRAB is suggested before transplant surgery after assessment of the local epidemiology. Careful consideration of the laboratory workload and involvement of antimicrobial stewardship teams before implementing the screening procedures or performing changes in PAP are warranted. High-quality prospective studies to assess the impact of PAP among CRE and CRAB carriers performing high-risk surgeries are advocated. Future well-designed clinical trials should assess the effectiveness of targeted PAP, including the monitoring of MDR-GNB colonization through postoperative cultures using European Committee on Antimicrobial Susceptibility Testing clinical breakpoints. - PublicationEndophthalmitis caused by Enterococcus casseliflavus: a systematic review of literature(European Academy of HIV/AIDS and Infectious Diseases, 2023)
;Stylianos A Kandarakis ;Nikolaos Spernovasilis ;Ilias Georgalas ;Michalis Mendris ;Aris P AgouridisIntroduction Enterococcus casseliflavus is a rare pathogen in human infections, despite being widely distributed in natural environments. This systematic review aims to evaluate the evidence related to endophthalmitis caused by E. casseliflavus. Methods A thorough search of PubMed, PubMed Central, and Scopus databases was conducted, covering the period up to October 2022. Results A total of 53 records were identified, with 8 studies reporting a total of 21 cases meeting the inclusion criteria. Among these studies, 7 described isolated case reports, while 1 study described 14 cases. The overall quality of the reports was good, as all articles were determined to have low risk of bias. Vancomycin susceptibility was reported in only one case of isolated case reports, while the remaining cases were all vancomycin resistant. With regard to management, in most cases intravenous ampicillin and linezolid were administered, while only one study reported administration of vancomycin. Conclusions Ophthalmologists should be aware of the potential for E. casseliflavus to cause endophthalmitis infections and the challenges associated with its intrinsic resistance to vancomycin. - PublicationRole of gender in hesitancy toward the COVID-19 vaccine beyond medical students(European Academy of HIV/AIDS and Infectious Diseases, 2023)

;Elena Carrara ;David S.Y. Ong ;Khetam Hussein ;Siran Keske ;Anders F. Johansson ;Elisabeth Presterl ;Sarah Tschudin-Sutter ;Evelina TacconelliScope: This guideline addresses the indications for direct testing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in asymptomatic individuals in health care facilities, with the aim to prevent SARS-CoV-2 transmissions in these settings. The benefit of testing asymptomatic individuals to create a safe environment for patients and health care workers must be weighed against potential unintended consequences, including delaying necessary treatments owing to false positive results and lower quality of care owing to strict isolation measures. Methods: A total of nine PICOs (population, intervention, comparison, outcome) on the topic of testing asymptomatic individuals was selected by the panel members. Subsequently, a literature search for existing guidelines and systematic reviews was performed on PubMed, Epistemonikos, and RecMap using relevant filters available in each database. Data on article/recommendation type, setting, target population, intervention, and quality of the evidence were extracted. Credibility of the systematic reviews was evaluated using the AMSTAR tool, and level of agreement with available recommendation was evaluated with the AGREE II score. Because the evidence available from systematic reviews was deemed insufficiently updated to formulate relevant recommendations, an additional search targeting relevant guidance documents from major public health institutions and original studies was performed. Provisional recommendations were discussed via web conferences until agreement was reached, and final recommendations were formulated according to the GRADE approach. Recommendations: Recommendations were formulated regarding systematic testing in asymptomatic individuals upon admission to a health care setting, during hospital stay, before elective procedures, and before scheduled nonsurgical procedures. Moreover, recommendations regarding testing of asymptomatic visitors, personal caregivers, and health care workers in health care facilities were presented. Recommendations also were given on contact tracing in asymptomatic patients or health care workers and the possibility of a negative screening test to shorten the quarantine period. Furthermore, if applicable, recommendations were specified to transmission rate and vaccination coverage. - PublicationTransmission of Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae: the role of infection controlBackground: The worldwide spread of carbapenemase-producing Gram-negative bacteria (GNB) in healthcare settings is worrying. Of particular concern is the occurrence of Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (KP). In recent years, several guidelines and recommendations have focused on the control of carbapenem-resistant GNB. It remains, however, unknown to what extent individual infection control measures are effective. Our aim was to critically review the recent evidence regarding the effectiveness of measures to control KPC-KP spread in healthcare settings. Methods: Critical review of the literature aiming to evaluate, in accordance with published recommendations, all available studies reporting infection control (IC) measures to control KPC-KP published in the past 5 years. Results: Among 11 included studies, the majority consisted of outbreak reports, where application of measures was reported in the absence of control groups. Variability was observed related to the frequency of application of recommended measures for control of KPC-KP. Additional measures were recorded, such as environmental sampling and staff screening, whereas compliance with hand hygiene was measured in relatively few studies. Finally, mortality in patients harbouring KPC-KP was notable, reaching 42.9% of included patients. Conclusions: Despite successful control of KPC-KP spread during outbreaks, the impact of individual IC measures is difficult to assess, as the quality of published evidence is low and controlled intervention studies are lacking. The distribution of studies, the number of reported cases and the high mortality rates, clearly show that KPC-KP remains a major healthcare problem worldwide.
- PublicationNot surprising: a rebound in antibacterial consumption in Europe, with Cyprus and Greece on the podiumRecent European-wide data place Cyprus and Greece in the highest positions of total antimicrobial consumption. While this level of consumption might be partly attributed to the high rates of infections due to MDR bacteria in these countries, several other reasons should be sought to help apply local measures, to decrease inappropriate and excess antimicrobial use. The present viewpoint aims to provide a roadmap for interventions, by briefly discussing the various factors that underlie antimicrobial use and prescribing practices in Greece and Cyprus.
