Increase of multidrug-resistant bacteria after the COVID-19 pandemic in a major teaching Hospital in Sicily (2018-2021).

INTRODUCTION: The COVID-19 pandemic has further highlighted the continuing threat of antimicrobial resistance (AMR) to global health and economic development. In the last two decades, AMR has raised increasing concern, with an estimated 4.95 million deaths globally due to bacterial AMR in 2019 alone. The aim of this study was to analyse the impact of the pandemic on the spread of multidrug-resistant organisms (MDROs) using data from the Hospital "P. Giaccone" in Palermo, comparing pre-pandemic and pandemic periods. METHODS: This observational study involved adult patients who were discharged from the hospital between 01 January 2018 and 31 December 2021. Hospital Discharge Cards were linked with microbiological laboratory reports to assess MDRO isolations. SARS-CoV-2 positivity during hospitalisation was evaluated using the National Institute of Health surveillance system. RESULTS: A total of 58 427 hospitalisations were evaluated in this study. Half the patients were aged over 65 years (N=26 984) and most admissions were in the medical area (N=31 716). During the hospitalisation period, there were 2681 patients (5%) with MDROs isolations, and 946 patients (2%) were positive for SARS-CoV-2. Multivariable analyses showed that during 2020 and 2021, there was a significantly increased risk of isolation of Staphylococcus aureus, Acinetobacter baumannii, and Klebsiella pneumoniae. Age, weight of the Diagnosis-Related Group (DRG), wards with higher intensity of care, and length-of-stay were associated with a higher risk of MDRO isolation. CONCLUSION: This study provides new insights into the impact of the COVID-19 pandemic on MDRO isolation and has important implications for infection control and prevention efforts in healthcare facilities. Age, DRG-weight, and longer hospital stays further increased the risk of MDRO isolation. Thus, it is imperative to improve and follow hospital protocols to prevent healthcare-associated infections.

Birth characteristics as predictors of respiratory syncytial virus hospitalisation in newborns to optimise immunisation schedule.

AIM: To examine birth characteristics that influence infant respiratory syncytial virus (RSV) hospitalisation risk in order to identify risk factors for severe RSV infections. METHODS: Retrospective cohort study of 460 771 Sicilian children under 6 months old from January 2007 to December 2017. Hospital discharge records were consulted to identify cases and hospitalisations with International Classification of Diseases, Ninth Revision, Clinical Modification codes 466.11 (RSV bronchiolitis), 480.1 (RSV pneumonia) and 079.6 (RSV). RSV hospitalisation risk was estimated using adjusted odds ratios (aOR) and 95% confidence intervals (95% CI). RESULTS: Overall, 2420 (5.25 per 1000 infants) RSV-related hospitalisations were identified during the study, with girls accounting for 52.8%. RSV hospitalisation risk increased for full-term, transferred, extreme immature, and preterm neonates with serious issues (aOR 3.25, 95% CI 2.90-3.64; aOR 1.86, 95% CI 1.47-2.32; aOR 1.54, 95% CI 1.11-2.07; and aOR 1.48, 95% CI 1.14-1.90). Compared to children born in June, the risk of RSV hospitalisation was significantly higher in children born in January (aOR 28.09, 95% CI 17.68-48.24) and December (aOR 27.36, 95% CI 17.21-46.99). CONCLUSION: This study identified birth month and diagnosis-related groups as key predictors of RSV hospitalisations. This could help manage monoclonal antibody appropriateness criteria.

Low Risk of SARS-CoV-2 Reinfection for Fully or Boosted mRNA Vaccinated Subjects in Sicily: A Population-Based Study Using Real-World Data.

Background: Reinfections occur as a response to natural infections wanes and novel strains of SARS-CoV-2 emerge. The present research explored the correlation between sex, age, COVID-19 vaccination, prior infection hospitalization, and SARS-CoV-2 reinfection in Sicily, Italy. Materials and Methods: A population-based retrospective cohort study was articulated using the vaccination flux from a regional registry and the Sicilian COVID-19 monitoring system of the Italian Institute of Health. Only adult Sicilians were included in the study, and hazard ratios were calculated using Cox regression. Results: Partial vaccination provided some protection (adj-HR: 0.92), when compared to unvaccinated individuals; furthermore, reinfection risk was reduced by full vaccination (adj-HR: 0.43), and the booster dose (adj-HR: 0.41). Males had a lower risk than females of reinfection with SARS-CoV-2 (adj-HR: 0.75). Reinfection with SARS-CoV-2 was diminished by hospitalization during the first infection (adj-HR: 0.78). Reinfection risk was higher among those aged 30-39 and 40-49 compared to those aged 18-29, whereas those aged 60-69, 70-79, and 80+ were statistically protected. Reinfection was significantly more frequent during the wild-type-Alpha, Delta, Delta-Omicron, and Omicron dominance/codominance waves compared to the wild type. Conclusions: This study establishes a solid base for comprehending the reinfection phenomenon in Sicily by pinpointing the most urgent policy hurdles and identifying some of the major factors. COVID-19 vaccination, one of the most effective public health tools, protects against reinfection, mostly caused by the Omicron strain. Elderly and hospitalized people's lower risk suggests stricter PPE use.

Effectiveness of mRNA Vaccine Booster against SARS-CoV-2 Infection and COVID-19 in the Adult Population during the First Three Months of the Omicron Wave in Sicily.

BACKGROUND: In Italy, the administration of the COVID-19 vaccine booster dose started on 27 September 2021, supported by clinical trials corroborating its efficacy. Given the paucity of real-world effectiveness data, this study aims to estimate the vaccine effectiveness of the booster dose against SARS-CoV-2 infection, severe disease, and death in the adult Sicilian population. METHODS: This retrospective cohort study was carried out from 1 January to 31 March 2022 and included all residents in Sicily aged ≥ 18 years without previous SARS-CoV-2 infection and with a complete mRNA vaccine primary cycle. The cohort was split into two groups (booster and primary cycle) matched by age, gender, vaccine type, and month of completion of the primary vaccination cycle. RESULTS: 913,382 subjects were observed in the study: 456,690 (50%) were vaccinated with two doses and 456,692 (50%) with three doses. There were 43,299 cases of SARS-CoV-2 among the two-doses vaccinees (9.5%) and 10,262 (2.2%) among the three-doses counterpart. Vaccine effectiveness in the booster cohort was 76.5% and 74.4% against SARS-CoV-2 infection, 85.7% and 79.7% against severe disease, and 84.1% and 73.1% against intubation or death, for BNT162b2 and mRNA-1273, respectively. CONCLUSIONS: This study confirmed the remarkable efficacy profile of the SARS-CoV-2 vaccine booster dose against infection, severe disease, and death attributable to the virus. Overall, the results of this study provide important real-world data to support the continued roll-out of the COVID-19 booster dose and have the potential to inform public health policy and guide decisions on vaccination strategies in countries around the world.

Effectiveness of mRNA COVID-19 Vaccines in Adolescents Over 6 Months.

BACKGROUND AND OBJECTIVES: On June 4, 2021, Italy launched the coronavirus disease 2019 (COVID-19) vaccination of adolescents to slow down the COVID-19 spread. Although clinical trials have evaluated messenger ribonucleic acid (mRNA) vaccine effectiveness in adolescents, there is limited literature on its real-world effectiveness. Accordingly, this study aimed to estimate the effectiveness of mRNA COVID-19 vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and mild or severe COVID-19 in a cohort of Sicilian adolescents within a 6 month observation period. METHODS: A retrospective cohort study was conducted with adolescents aged 12 to 18 years, residents of Sicily, who were followed from July 15 to December 31, 2021. SARS-CoV-2 infections, mild and severe COVID-19, and COVID-19-related intubation or deaths during the study period were compared between subjects vaccinated with 2 doses of mRNA vaccines and unvaccinated individuals. The Cox regression analysis, adjusted for age and sex, was performed to compare the 2 groups. RESULTS: Overall, the study included a total at-risk population of 274 782 adolescents with 61.4% of them having completed the vaccination cycle by the end of the study. Unvaccinated subjects had higher incidence rates of SARS-CoV-2 (1043 × 10 000 vs 158.7 × 10 000 subjects), mild COVID-19 (27.7 × 10 000 vs 1.8 × 10 000 subjects) and severe COVID-19 (1.41 × 10 000 vs 0 subjects) compared with the vaccinated population. The estimated adjusted vaccine effectiveness against SARS-CoV-2 infection was 71.2%, reaching 92.1% and 97.9% against mild and severe COVID-19, respectively. CONCLUSIONS: This study provides rigorous evidence of mRNA COVID-19 vaccines' effectiveness in protecting adolescents from both SARS-CoV-2 infection and COVID-19.

Effectiveness of mRNA COVID-19 Vaccination on SARS-CoV-2 Infection and COVID-19 in Sicily over an Eight-Month Period.

In order to reduce the spread of SARS-CoV-2 infection and the burden of disease, since 27 December 2020, Sicily has introduced a regional COVID-19 vaccination campaign. This study aimed at estimating the effectiveness of mRNA COVID-19 vaccines on SARS-CoV-2 infections and COVID-19. A retrospective cohort study was carried out on 3,966,976 Sicilian adults aged 18 years or more, who were followed-up from 1 January 2021 to 30 September 2021. The risk of SARS-CoV-2 infection, severe COVID-19, and COVID-19 death or intubation during the study period was compared among vaccinated with two mRNA doses and unvaccinated individuals. Cox regression, adjusted for age and sex, and a joint-point analysis on rate trends were performed. Overall, 2,469,320 (62.2%) subjects have been vaccinated and a total of 103,078 (2.6% of the entire population) SARS-CoV-2-positive subjects have been observed including 4693 (0.12%) severe COVID-19, 277 (0.01%) intubated, and 2649 (0.07%) deaths. After two months from vaccination, adjusted vaccine effectiveness was 81.3% against SARS-CoV-2 infection, 96.1% against severe COVID-19, and 93.4% against intubation/death. During the eight-month follow-up, statistically significant decreasing effectiveness trends were observed for all the evaluated outcomes (-4.76% per month against SARS-CoV-2 infection; -2.27% per month against severe COVID-19 and -2.26% per month against COVID-19 intubation/death). The study results confirm that mRNA COVID-19 vaccines have high real-world effectiveness, especially in the first months after vaccination. The vaccine effectiveness decreases over time and, even if the decrease is relatively small against severe outcomes, the increasing protection wane suggests the need for booster vaccination campaigns.

CITIZENS OBTAINING PSYCHOSOCIAL SUPPORT DURING THE COVID-19 PANDEMIC IN UKRAINE: A CROSS-SECTIONAL STUDY.

OBJECTIVE: The aim: To investigate the obtaining of psychosocial support by citizens during the COVID-19 pandemic in Ukraine using a cross-sectional study assessing the socio-demographic characteristics of the respondents. PATIENTS AND METHODS: Materials and methods: It was developed and used the authors' questionnaire "Socio-psychological support during the COVID-19 pandemic in Ukraine". Data processing used Nonparametric Mann-Whitney analysis of variance and one-way Kruskal-Wallis analysis of variance (SPSS 26.0). RESULTS: Results: The study was conducted from October 2020 to May 2021 and sampled 100 individuals. Significant differences in the studied features are revealed. Gender: women have a more prosperous and broader range of contacts to discuss fears and anxieties during quarantine; suffer more from emotional loss; have more need to be heard and to be taken care of, with no criticism; are more experienced in professional psychological help obtaining; communicate with internal migrants more often. Age: young respondents (19-24 y.o.) suffer more from pandemic losses in the areas of spirituality and friendship; however, more often and more effectively use the means of online psychological support; older respondents are more likely to receive support from an important community and through meditation. Living conditions: living alone, citizens experience more pandemic stress, suffer from losses in personal life and friendship, and consider participation in challenge activities as the most convenient form of support. Place of residence: living in the rural areas is associated with a narrow circle of citizens' contacts to discuss their plans for leisure; more significant damage from pandemic losses in health; lack of support in the form of understanding themselves and their conditions. Education: higher education affects a broader circle of communication; more minor financial losses; willingness to share traumatic stories for art therapy. Financial satisfaction promotes the exchange of ideas between users of online psychological support. CONCLUSION: Conclusions: The identified conditionality of psychosocial support obtaining by socio-demographic indicators can be used in the development of psychosocial support interventions during a pandemic for Ukrainian citizens by the public and private sectors, particularly in creating specialized smartphone applications, adapting playback theatre in the online space, creating gender-sensitive online programs to integrate IDPs into local communities.

PERSONALITY FACTORS OF EMOTIONAL RESILIENCE IN THE CHALLENGING ENVIRONMENTS FOR MENTAL HEALTH.

OBJECTIVE: The aim: The article presents the results of an empirical study aimed at identifying individual typological profiles of people with different potential for emotional resilience development. PATIENTS AND METHODS: Materials and methods: The authors identify a set of characteristics that determine emotional resilience development and suggest standardized methodologies to measure their intensity level (Eysenck Personality Inventory (EPI), Strelau Temperament Inventory (STI), Thurstone Temperament Schedule adapted by Khainovski, and the Leonhard-Schmieschek questionnaire). The outcomes of the data processed in the R environment have allowed the determination of the parameters of the psychological profile of an average client and identification of the traits that have the strongest impact on emotional resilience development. RESULTS: Results: The constructed factor-correlation-cluster model based on the mean data values for each of the respondents' psychological profiles contains three superclusters: 1) orientation at outer/inner world, 2) behavioral determination stability, 3) reflectivity. Accordingly, six types of psychological profiles of individuals with different potential for emotional resilience development have been determined. The six types are: 1) outward-oriented (looking) type; 2) inward-oriented type; 3) stable behavioral determination type; 4) unstable behavioral determination type; 5) reflectivity-oriented type; 6) reflectivity- non-oriented type. The authors describe the structure and peculiarities of manifestation of the individual psychological characteristics within each supercluster. The behavioral manifestations that facilitate or hinder the development of emotional resilience of individuals belonging to certain profiles are also described. CONCLUSION: Conclusions: The implementation prospects of the developed typology of psychological profiles of individuals with different emotional resilience resources are related to providing client-oriented support of emotional resilience development. Further research will address the development, piloting and implementation of the socio-psychological strategies of emotional resilience development support based on the suggested psychological profile typology.

Acute onset of paraganglioma of filum terminale: A case report and surgical treatment.

INTRODUCTION: Paragangliomas of filum terminale are rare benign tumors, arising from the adrenal medulla or extra-adrenal paraganglia. These lesions usually present with chronic back pain and radiculopathy and only two cases of acute neurological deficit have been reported in literature. PRESENTATION OF CASE: A case with an acute paraplegia and cauda equina syndrome due to an hemorrhagic paraganglioma of the filum terminale is described. Magnetic resonance imaging showed an intradural tumor extending from L1 to L2 compressing the cauda equina, with an intralesional and intradural bleed. An emergent laminectomy with total removal of the tumor was performed allowing a post-operative partial sensory recovery. Histopathological examination diagnosed paraganglioma. DISCUSSION: Paragangliomas are solid, slow growing tumors arising from specialized neural crest cells, mostly occurring in the head and neck and rarely in cauda equina or filum terminale. MRI is gold standard radiological for diagnosis and follow-up of these lesions. They have no pathognomonic radiological and clinical features and are frequently misdiagnosed as other spinal lesions. No significant correlation was observed between the duration of symptoms and tumor dimension. Acute presentation is unusual and emergent surgical treatment is fondamental. The outcome is very good after complete excision and radiotherapical treatment is recommended after an incomplete resection. CONCLUSION: Early radiological assessment and timely surgery are mandatory to avoid progressive neurological deficits in case of acute clinical manifestation of paraganglioma of filum terminale.
