Concomitant Resistance to Cefiderocol and Ceftazidime/Avibactam in Two Carbapenemase-Producing Klebsiella pneumoniae Isolates from Two Lung Transplant Patients.

In this study, we present two cases of Klebsiella pneumoniae, one KPC-33- and one NDM-1-producing, showing resistance to cefiderocol and ceftazidime/avibactam, collected in the intensive care unit of a hospital in Northern Italy from two patients who had recently undergone lung transplantation. Whole-genome sequencing was performed to investigate the molecular features of these strains.

Strongyloides stercoralis infection: an underlying cause of invasive bacterial infections of enteric origin. Results from a prospective cross-sectional study of a northern Italian tertiary hospital.

We assessed the prevalence of S. stercoralis in a cohort of inpatients with invasive bacterial infections of enteric origin to investigate whether the parasite may facilitate these bacterial infections even in the absence of larval hyperproliferation. We performed a prospective cross-sectional study in a hospital in northern Italy. Subjects admitted due to invasive bacterial infection of enteric origin and potential previous exposure to S. stercoralis were systematically enrolled over a period of 10months. S. stercoralis infection was investigated with an in-house PCR on a single stool sample and with at least one serological method (in-house IFAT and/or ELISA Bordier). Univariate, bi-variate and logistic regression analyses were performed. Strongyloidiasis was diagnosed in 14/57 patients (24.6%; 95% confidence interval 14.1-37.8%) of which 10 were Italians (10/49, 20.4%) and 4 were migrants (4/8, 50.0%). Stool PCR was performed in 43/57 patients (75.4%) and no positive results were obtained. Strongyloidiasis was found to be significantly associated (p ≤ 0.05) with male gender, long international travels to areas at higher endemicity, deep extra-intestinal infectious localization and solid tumors. In the logistic regression model, increased risk remained for the variables deep extra-intestinal infectious localization and oncologic malignancy. Our findings suggest a new role of chronic strongyloidiasis in favoring invasive bacterial infections of enteric origin even in the absence of evident larval dissemination outside the intestinal lumen. Further well-designed studies should be conducted to confirm our results, and possibly establish the underlying mechanisms.

Combining Genome Surveillance and Metadata To Characterize the Diversity of Staphylococcus aureus Circulating in an Italian Hospital over a 9-Year Period.

Staphylococcus aureus is an opportunistic pathogen and a leading cause of morbidity and mortality worldwide. Genomic-based surveillance has greatly improved our ability to track the emergence and spread of high-risk clones, but the full potential of genomic data is only reached when used in conjunction with detailed metadata. Here, we demonstrate the utility of an integrated approach by leveraging a curated collection of clinical and epidemiological metadata of S. aureus in the San Matteo Hospital (Italy) through a semisupervised clustering strategy. We sequenced 226 sepsis S. aureus samples, recovered over a period of 9 years. By using existing antibiotic profiling data, we selected strains that capture the full diversity of the population. Genome analysis revealed 49 sequence types, 16 of which are novel. Comparative genomic analyses of hospital- and community-acquired infection ruled out the existence of genomic features differentiating them, while evolutionary analyses of genes and traits of interest highlighted different dynamics of acquisition and loss between antibiotic resistance and virulence genes. Finally, highly resistant clones belonging to clonal complexes (CC) 8 and 22 were found to be responsible for abundant infections and deaths, while the highly virulent CC30 was responsible for rare but deadly episodes of infections. IMPORTANCE Genome sequencing is an important tool in clinical microbiology, as it allows in-depth characterization of isolates of interest and can propel genome-based surveillance studies. Such studies can benefit from ad hoc methods of sample selection to capture the genomic diversity present in a data set. Here, we present an approach based on clustering of antibiotic resistance profiles that allows optimal sample selection for bacterial genomic surveillance. We apply the method to a 9-year collection of Staphylococcus aureus from a large hospital in northern Italy. Our method allows us to sequence the genomes of a large variety of strains of this important pathogen, which we then leverage to characterize the epidemiology in the hospital and to perform evolutionary analyses on genes and traits of interest. These analyses highlight different dynamics of acquisition and loss between antibiotic resistance and virulence genes.

Mental Health Issues as a Consequence of the Pandemic: Group Psycho-Educational Intervention to Support Patients Recovered from COVID-19 Infection

Common psycho-physical symptoms have emerged in patients who were previously recovered for COVID-19 infection, including traumatic experience and enduring emotional disturbances. A group psycho-educational intervention of seven weekly sessions and a follow-up after three months was proposed to all Italian-speaking patients formally discharged from a public hospital in northern Italy and physically recovered from infection. Eighteen patients were recruited and divided into four age-homogenous groups, each led by two facilitators (psychologists and psychotherapists). The group sessions followed a structured format with thematic modules, including main topics, tasks, and homework assignments. Data were collected through recordings and verbatim transcripts. The objectives of the study were twofold: (1) to analyze the emerging themes and gain insight into the significant aspects of the participants’ lived experience of COVID-19, and (2) to examine changes in how participants approached these themes throughout the intervention process. Semantic-pragmatic text analyses, specifically thematic analysis of elementary context and correspondence analysis, were conducted using T-LAB software. Linguistic analysis revealed a congruence between the intervention’s objectives and the participants’ experiences. The study highlighted an evolution in the narratives, as participants transitioned from a passive and concrete perspective on the disease to a more comprehensive cognitive and emotional elaboration of their personal illness stories. These findings hold potential relevance for healthcare services and professionals working in this field.

Prevalence of Self-Reported Hand Eczema Signs among Healthcare Workers after the Third Wave of COVID-19 Pandemic: A Survey in a Northern Italy Hospital.

Background: Proper hand hygiene is one of the enhanced preventive measures immediately proposed to avoid the spreading of the severe acute respiratory syndrome coronavirus-2, also known as COVID-19. Objectives: The objective of this study was to estimate the prevalence of self-reported hand eczema signs and symptoms among healthcare workers in a Northern Italy University Hospital after the third wave of the COVID-19 pandemic. Materials and methods: A cross-sectional study was conducted in June 2021. The hospital workers were invited to complete an online questionnaire through a link sent via institutional e-mail to both health personnel and support staff. Results: Eight-hundred and sixty-three subjects completed the questionnaire; 51.1% of them self-reported suffering from at least one hand skin lesion. One-hundred thirty-seven responders declared that they changed their hand hygiene habits, and 88.9% of them carried out these modifications both in occupational and domestic environments. In detail, a change in terms of daily hand washing frequency is reported as follows: before the COVID-19 pandemic, only 27.8% and 10.1% of responders washed their hands 10-20 and 20+ times per day, respectively, while after the pandemic, the percentage increased to 37.8% and 45.8%, respectively. When comparing the health care workers with the administrative staff, we observed a statistically significative difference (p = 0.0001) in the daily hand washing frequency among the two groups, with a higher value in health care personnel. Accordingly, a higher prevalence of hand eczema signs (52.8% versus 45.6%) was detected in the healthcare group. Conclusions: We underline the potential role of the pandemic in the spread of hand eczema as an occupational disease and the need to implement its prevention.

Spontaneous Changes in Attentional Capabilities and Reasoning After an Alcohol Rehabilitation Treatment: Evidence About the Role of Age and Alcohol Use.

In this study, we evaluated changes in attentional capabilities and reasoning among early abstinent alcohol-dependent individuals after a 28-day residential rehabilitation program (not including cognitive treatment). Furthermore, we explored the role of individual characteristics and disease-related factors (i.e., length of alcohol use, history of polysubstance dependence, severity of alcohol use) on spontaneous cognitive recovery. Fifty-five patients with a diagnosis of Alcohol Use Disorder (AUD) were consecutively recruited from a residential rehabilitation hospital in Northern Italy. The majority were male (67.3%) with a mean age of 47.83 years (SD = 8.21). The computerized Psychology Experiment Building Language Test Battery was used to assess the performance at the Posner Cueing Test, Go/no-go Task, Trail Making Test (TMT), Tower of London (TOL), and Balloon Analog Risk Scale. The evaluation was performed twice: at the beginning (T0) and at its end (T1, before the hospital discharge). We observed statistically improvements over time in the performance at the: 1) TOL in the time amount required to solve the task (p < 0.001); and 2) TMT in the indexes relative to the number of errors (p = 0.003) and the total time required to solve the task (p < 0.001). Age played a significant role on the changes observed in the score relative to the time amount used by participants to solve the task in TMT (test (p = 0.03) and in TOL (p = 0.02). Moreover, the length of alcohol dependence had an effect on the change observed for the time amount to solve the TMT (time) (p = 0.01). We found spontaneous recovery after alcohol detoxification on some, but not all, cognitive functions assessed in our study. The neuropsychological assessment and the identification of patients with cognitive impairment and specific risk factors (e.g., older age and longer history of alcohol use) is important to orient cognitive rehabilitation and increase the efficacy of AUD treatments.

Pain Intensity, coping and maternal satisfaction in Low-Risk labouring Women: A prospective descriptive correlational study

ObjectivesThe primary aim of the study was to explore pain intensity (PI) and pain coping (PC) scores and the relationship between them. The secondary aim was to explore the correlation between PI and PC scores with labour progress, parity, labour acceleration, labour augmentation and maternal satisfaction. MethodsA prospective descriptive correlational study was conducted in a maternity hospital in Northern Italy. The sample included 54 low-risk women in active labour at term of pregnancy. A data record sheet was used to collect the relevant variables and the Italian Birth Satisfaction Scale Revised (I-BSS-R) was administered to participants at least 24 h after birth. ResultsIn the first labour stage, the average PI score was 6.99 (SD = 1.95) and the average PC score was 6.5 (SD = 2.22). During the second labour stage, the average PI score was 7.75 (SD = 1.74) and the average PC score was 4.97 (SD = 2.76). The average PI score trend increased with labour progress. The average PC score improved between 4 and 7 cm of cervical dilatation. A significant positive correlation between PI scores and oxytocin augmentation (p < 0.001) and labour progression (p < 0.001) was noted. A significant positive correlation between PC scores and oxytocin augmentation (p = 0.02) was also observed. No significant differences were found for maternal satisfaction in regard to PI and PC scores. Conclusioncoping in labour do not solely depend on PI but also on labour progress and oxytocin augmentation. Additional support to empower women to cope with pain may be required in case of labour augmentation.

Epidemiology of Serratia marcescens infections in NICU of a Teaching and Research Hospital in Northern Italy.

Serratia marcescens (Sm) is a known cause of infection and colonization in neonates receiving intensive care. The aim of this study was to identify the risk factors for colonization and infection with Sm in Neonatal Intensive Care Unit (NICU) of a tertiary care Hospital. A case-control study was conducted from January to December 2011 in neonates admitted to the NICU. Cases are patients with a microbiologically confirmed infection or colonization, controls were randomly chosen among patients admitted to the same NICU. Globally, 39 acquired infections or colonizations were identified. Among factors related to pregnancy, only premature delivery was independently associated to the risk of infection; as well as mechanical ventilation and catheterization for parenteral nutrition, considering indwelling devices. Prolonged administration with antibiotics were also related to the risk of infection. Among Sm strains which have been tested to antibiotics, all have been resistant to amoxicillin/clavulanic acid and to colistin. This study confirms the association between Sm infection or colonization and low gestational age. Invasive medical devices and medications, strictly necessary in care-support of preterm neonates, are likely related to Sm infection too. Preventive control strategies are expected to be effective in the control of Sm spread in NICUs.

Cost-Effectiveness of Targeted Prophylaxis among Allogenic Stem Cell Transplant Recipients

Bloodstream infections (BSI) are life-threatening complications for onco-hematologic patients. Fluoroquinolones prophylaxis (FQP) was recommended for patients with neutropenia. Later, it was correlated with increased resistance rates among this population and its role became debated. While the role of FQ prophylaxis is still being studied, its cost-effectiveness is also unknown. The objective of this study was to evaluate the costs and effects associated with two alternative strategies (FQP vs. no prophylaxis) for patients with hematological malignancies undergoing allogenic stem cell transplant (HSCT). A decision-tree model was built integrating retrospectively collected data from a single transplant center, part of a tertiary teaching hospital in Northern Italy. Probabilities, costs and effects were considered in the assessment of the two alternative strategies. Probabilities of colonization, BSIs, extended-spectrum beta lactamase (ESBL) and Klebsiella pneumoniae carbapenemase (KPC) BSIs and mortality associated with infection, as well as median duration of length of stay (LOS) were calculated based on data collected between 2013 and 2021. The center applied the strategy of FQP between 2013 and 2016, and of no prophylaxis between 2016 and 2021. Data on 326 patients were collected during the considered time period. Overall, the rates of colonization, BSI, KPC/ESBL BSI, and mortality were 6.8% (95% confidence interval (CI) 2.7-13.5), 42% (9.9-81.4) and 20.72 (16.67-25.26), respectively. A mean bed-day cost of 132€ was estimated. Considering no prophylaxis vs. prophylaxis, the difference in costs ranged between additional 33.61 and 80.59€ per patient, whereas the difference in effects ranged between 0.11 and 0.03 life-years (LYs) lost (around 40 and 11 days). Given the small differences in terms of costs and effects between the two strategies, no prophylaxis seems an appropriate choice. Furthermore, this analysis did not consider the broader effect on hospital ecology of multiple doses of FQP, which could provide further support for the strategy of no prophylaxis. Our results suggest that the necessity for FQP in onco-hematologic setting should be determined based on local antibiotic resistance patterns.

Women’s attitudes about combined hormonal contraception (CHC) - induced menstrual bleeding changes - influence of personality traits in an Italian clinical sample

Objectives We investigated the attitudes to change the frequency of menstrual bleeding by using combined hormonal contraception (CHC). Personality characteristics were also explored. Methods We conducted a cross-sectional study in two university hospitals in northern Italy. Current, past and never CHC users (n = 545; age 18–44 years) completed a self-administered semi-structured questionnaire and the Ten-Item Personality Inventory (TIPI). Results Forty-five percent of responders (n = 301) would prefer to change their bleeding frequency by using CHC. A flexible regimen was the preferred choice (n = 80; 33%) followed by extended regimens to bleed every 3 months (n = 54; 22%) or to never bleed (n = 43; 18%). The main positive reasons were to avoid dysmenorrhea (43%) and have more freedom in sexual (36%) and active (35%) life, whereas the main reason for a negative attitude was ‘menstrual rhythm is natural’ (59%). Age had a significant influence on women’s willingness to change menstrual frequency by using CHC [>39 years (57%), 30–39 years (31%) and <30 years (46%)] (χ2: 9.1; p = 0.01). Never users significantly reported a more negative attitude (71%) in comparison with past (51%) and current users (49%) (χ2: 18.7; p = 0.001). Personality traits played a role, with higher scores of openness (p = 0.005) and extraversion (p = 0.001) in women with a positive attitude. Conclusions Almost half of our study sample reported a preference for changing their menstrual pattern by using CHC. Flexibility was the preferred choice across age and use of CHC. Personality characteristics (openness and extroversion) might influence attitudes toward CHC-induced menstrual bleeding changes.

The WEST Study: A Retrospective and Multicentric Study on the Impact of Steroid Therapy in West Nile Encephalitis.

The use of steroid therapy in potentially life-threatening neuroinvasive forms of West Nile infection (WNND) is controversial. The aim of this study is to assess the efficacy of steroid therapy in reducing intrahospital mortality, length of stay, and neurological sequelae at discharge. This was a multicenter, retrospective, observational study conducted in 5 hospitals in Northern Italy, headed by the Fondazione IRCSS Policlinico San Matteo (Pavia). We extracted all patient data with WNND diagnoses, comparing patients who received steroid treatment with patients who did not receive steroid treatment between January 2014 and January 2022. Comparisons between the 2 groups were performed using chi-square tests for categorical variables and Mann-Whitney tests for non-normal continuous data, and a generalized linear model for the binomial family was carried out. Data from 65 WNND patients were extracted. Among these patients, 33 (50.7%) received steroid therapy at any point during their hospitalization. Receiving steroid therapy did not significantly reduce intrahospital mortality (odds ratio [OR], 1.70; 95% CI, 0.3-13.8; P = .89) or neurological sequelae at discharge (OR, 0.53; 95% CI, 0.16-1.76; P = .47). Steroid treatment is currently used on a single-case basis in severe WNND. More prospective data are needed to demonstrate a protective effect on mortality and neurological sequelae.

Impact of BNT162b2 Booster Dose on SARS-CoV-2 Anti-Trimeric Spike Antibody Dynamics in a Large Cohort of Italian Health Care Workers.

Accurate studies on the dynamics of Pfizer-Biontech BNT162b2-induced antibodies are crucial to better tailor booster dose administration depending on age, comorbidities, and previous natural infection with SARS-CoV-2. To date, little is known about the durability and kinetics of antibody titers months after receiving a booster dose. In this work, we studied the dynamic of anti-Trimeric Spike (anti-TrimericS) IgG titer in the healthcare worker population of a large academic hospital in Northern Italy, in those who had received two vaccine doses plus a booster dose. Blood samples were collected on the day of dose 1, dose 2, then 1 month, 3 months, and 6 months after dose 2, the day of the administration of the booster dose, then 1 month and 3 months after the booster dose. The vaccination immunogenicity was evaluated by dosing anti-TrimericS IgG titer, which was further studied in relation to SARS-CoV-2 infection status, age, and sex. Our results suggest that after the booster dose, the anti-TrimericS IgG production was higher in the subjects that were infected only after the completion of the vaccination cycle, compared to those that were infected both before and after the vaccination campaign. Moreover, the booster dose administration exerts a leveling effect, mitigating the differences in the immunogenicity dependent on sex and age.

Development and validation of two versions of the Nurse-Patient Mutuality in Chronic Illness scale.

The aim of the study was to develop and psychometrically test the Nurse-Patient Mutuality in Chronic Illness (NPM-CI) scale in two versions, one for nurses and one for patients. A multiphase methodological study was conducted. In the first phase, a qualitative investigation was conducted through interviews and an analysis of the content; inductively, the items of two instruments were generated, one for nurses and one for patients. In the second phase, the content and face validity were assessed through the expert consensus method. In the third phase, exploratory factor analysis (EFA), Cronbach's alpha test, intraclass correlation and Pearson correlation coefficients were conducted to estimate construct, criterion validity and instrument reliability. For each phase, the sample included nurses and patients recruited from a large hospital in Northern Italy. Data collection was conducted between June and September 2021. Nurse and patient versions of the NPM-CI scale were developed. Two rounds of consensus reduced the items from 39 to 20; content validity index ranged between 0.78 and 1, content validity ratio was 0.94. Face validity indicated clarity and comprehensibility of the items. EFA identified three latent factors for both the scales. Internal consistency was satisfactory, with Cronbach's alphas ranging between .80 and .90. Test-retest stability was suggested, with an intraclass correlation coefficient of .96 (nurse scale) and .97 (patient scale). Predictive validity was established, with a Pearson correlation coefficient of .43 (nurse scale) and 0.55 (patient scale) between the mutuality scales and satisfaction in providing and receiving care. The results suggest that the NPM-CI scales are sufficiently valid and reliable for the clinical practice among chronic illness patients and the nurses caring for them. A more in-depth exploration of this construct in the context of nursing and patient outcomes is warranted. Patients were involved in all study phases. Mutuality is fundamental in the relationship between nurse and patient, based on trust, equality, reciprocity, and mutual respect. The NPM-CI scale was developed and psychometric estimated through a multiphase study in both nurse and patient versions. The NPM-CI scale measures the factors of 'developing and going beyond', 'being the point of reference' and 'deciding and sharing care'. The NPM-CI scale allows us to measure mutuality in clinical practice and research. Expected outcomes and influencing factors for patients and nurses could be associated.

The Healthcare Relationship during the Second Wave of the COVID-19 Pandemic: A Qualitative Study in the Emergency Department of an Italian Hospital.

The COVID-19 pandemic had an impact not only on people's lives but also on the healthcare system. This study aimed to investigate the healthcare relationship in the Emergency Department (ED) of a hospital in northern Italy, during the second wave of the COVID-19 pandemic. The participants (N = 43) consisted of 16 nurses, 6 doctors from the hospital ED, and 21 patients who accessed this department. Semi-structured interviews were carried out and a thematic analysis was conducted. The findings suggest that the COVID-19 pandemic brought both positive and negative changes to the healthcare relationship that are linked to changes in the organization of the ED and to participants' various experiences of the pandemic. The changes in this relationship should be monitored because they could have long-term effects on healthcare professionals' wellbeing, treatment outcomes, and the healthcare system. The findings from this study could be used to understand these changes and inform intervention strategies to improve the healthcare relationship.

85 ATRIAL FIBRILLATION INCIDENCE IN SARS-COV-2 INFECTED PATIENTS: PREDICTORS AND RELATIONSHIP WITH IN-HOSPITAL MORTALITY

Abstract Background Among the different CardioVascular (CV) manifestation of the COronaVIrus-related Disease (COVID) particular attention has been paid to arrhythmia and particularly to Atrial fibrillation (AF). The aim of our study was to assess the incidence of AF episodes in patients hospitalized for COVID and to evaluate its predictors and its relationship with in-hospital all-cause mortality. Methods We enrolled 3435 cases of SARS-CoV2 infection admitted in four hospitals in Northern Italy. We collected data on clinical history, vital signs, Intensive Care Unit (ICU) admission, laboratory tests and pharmacological treatment. AF incident and all-cause in-hospital mortality were considered as outcomes. Results 145 (4.2%) patients develop AF during hospitalization, with a median time of 3 days (IQR: 0, 11.5) from admission. Incident AF patients were older and had lower eGFR, lower platelet and lymphocytes count and higher C-Reactive Protein (CRP), were admitted more frequently to ICU and more frequently died compared to subjects that didn't present AF. At the Cox regression model significant determinants of incident AF were older age (HR 1.070; 95% CI: 1.048, 1.092), history of AF (HR 2.800; 95% CI: 1.465, 5.351), ischemic heart disease (HR 0.324; 95% CI: 0.130, 0.811) and ICU admission (HR 8.030; 95% CI: 4.511, 14.292). Incident AF was a predictor of all-cause mortality (HR 1.679; 95% CI: 1.170, 2.410), together with age (HR 1.053; 95% CI: 1.042, 1.065), dementia (HR 1.553; 95% CI 1.151, 2.095), platelet count (HR 0.997; 95% CI: 0.996, 0.999) higher CRP (HR 1.004; 95% CI: 1.003, 1.005) and eGFR (HR: 0.991; 95% CI: 0.986, 0.996) Conclusion AF present as the main arrhythmia in COVID-19 patients and its development during the hospitalization strongly relates with in-hospital mortality.

144. Gram Negative Bacteria with Increased Minimal Inhibitory Concentration for Cefiderocol among Pediatric Patients in a Northern Italy Hospital.

Abstract Background Cefiderocol is a siderophore cephalosporin active against Gram negative (GN) carbapenem resistant bacteria, approved in Italy in September 2020 for adult patients. In pediatric population off label use is allowed when severe infections from multidrug resistance (MDR) GN bacteria occur. Recently, some authors reported the emergence, among strains of Enterobacterales resistant to ceftazidime avibactam, of cross-resistance with cefiderocol. The aim of this study is to describe GN strains with increased Minimal Inhibitory Concentration (MIC) for cefiderocol isolated in our hospital. Methods This is a retrospective, single-center study conducted in Istituto Giannina Gaslini Pediatric Hospital (Genoa, Italy) from 1st January 2020 to 31st April 2022. We collected all strains of MDR GN bacteria whit increased MIC for cefiderocol isolated in our hospital. Cefiderocol susceptibility testing was performed by disk diffusion assay with the disk of 30 μg (Kirby-Bauer method, KB) according to EUCAST’s recommendations and KB breakpoints. We collected demographical data, previous colonization (if note), carbapenemases production, clinical outcomes (infections from MDR; death at 7 and 30 days; ICU admission). Results Overall, 10 GN strains with increased MIC for cefiderocol were collected. 9/10 were Enterobacterales (4 Escherichia coli, 2 Enterobacter cloacae complex, 3 Klebsiella pneumoniae), one was Acinetobacter baumannii. 8/10 patients were admitted to other hospital in the six months before admission in our hospital, data about previous colonization were unknown. All MDR isolated produced metallo-β-lactamase [MBL] (5/10 New Delhi metallo-β-lactamase [NDM], 5/10 Verona integron-encoded metallo β-lactamase [VIM]). Four patients developed infection due to MDR (2 urinary tract infections, 1 bloodstream infection, 1 surgical wound), 2/4 patients died during the hospitalization. Conclusion Our study confirms that MDR producing MBL carbapenemases may have reduce susceptibility to cefiderocol, even if never exposed to this siderophore cephalosporin. Due to the possibility of cross resistance with MDR resistant to ceftazidime/avibactam, cefiderocol should be carefully prescribe in empirical treatment of MBL producers strains.

1942. Effect of SARS-CoV-2 Vaccination in a Frailty COVID-19 Cohort: a Real Life Experience in a Northern Italy Hospital

Abstract Background Clinical trial demonstrated that SARS-CoV-2 vaccines have the ability of reduce mortality and morbidity due to COVID-19. The aim of this study is to describe the effect of vaccination in term of mortality, type of ventilation and ICU admission among patients hospitalized for COVID-19 from May to December 2021 in a Ligurian Hospital. Methods This is a retrospective, single-center study conducted in San Martino Hospital (Genoa, Italy), including patients ≥ 18 years hospitalized for COVID-19 in Infectious Disease and Emergency Units from 1st May to 31st December 2021. We collected demographical data, multimorbidity and disability score, vaccination time (“vaccinated” all patients hospitalized ≥ 14 days after first dose or ≥ 7 days after second/third dose), therapy for COVID-19, mortality at 7 and 30 days, ICU admission, ventilation type. Characteristics of vaccinated (group A) versus non vaccinated (group B) patients were compared using Chi-squared/Fisher's exact test for categorical variables and t-test /Kruskal-Wallis test for the continuous ones. Cox proportional hazards models for death at 30 days were performed as univariate analysis as well as adjusting for age, Cumulative Illness Rating Scale [CIRS], gender, Remdesivir, Monoclonal antibodies, Tocilizumab use. Results Overall, 405 patients SARS-CoV-2 infected were enrolled. Data about timing of vaccination were available for 360 patients (89%). We compared clinical characteristics and outcomes of group A (32%) versus group B (68%). In group A patients were older (p&amp;lt; 0.001) and frailer (higher CIRS score and lower Barthel index, p&amp;lt; 0.001) than in group B. Among patients requiring oxygen, 76 (31.5%) in group B vs 26 (22.41%) in group A needed high flow ventilation (p=0.036); 33 (13.52%) vs 3 (2.59%) respectively were admitted to ICU (Figure 1). Mortality at 30 days after hospitalization was higher in group A at univariate analysis [HR(95%CI) 1.44(0.82; 2.53), p=0.208], lower at multivariate analysis [0.57(0.31; 1.02), p=0.059]. Conclusion The results of this study confirm that SARS-CoV-2 vaccination reduces rate of admission to ICU and 30 days mortality among patients hospitalized for COVID-19. In our cohort mortality among vaccinated patients remains high and we hypothesized this is due to high frailty of evaluated population.

Hospital Outcomes in Non COVID Wards at a Northern Italy Hospital during COVID 19 Pandemic

Hospital Outcomes in Non COVID Wards at a Northern Italy Hospital during COVID 19 Pandemic

The process of learning and professional development according to nursing students’ experience during Covid-19: A constructivist grounded theory study

AimThis study explored the experiences of nursing students with respect to learning processes and professional development during internships with COVID-19 patients to build a novel theoretical model. BackgroundThe COVID-19 outbreak had a profound impact on the worldwide learning system and it interrupted the internship experiences of nursing students. After the second wave of COVID-19, to balance academic activities with COVID-19 containment, some Italian universities allowed nursing students’ internships in COVID-19 units. This new experience may have influenced nursing students’ learning processes and professional development, but this is yet to be investigated. DesignA qualitative study using a constructivist grounded theory (CGT) approach. MethodsNursing students were recruited from two hospitals in northern Italy between January and April 2021. Data are gathered from interviews and a simultaneous comparative analysis were conducted to identify categories and codes, according to Charmaz’s (2006) theory. ResultsThe sample consisted of 28 students. The results suggested the core category, that is the ‘Students’ sense of belonging to the nursing profession’ and four main categories: (1) From knowledge to know-how, (2) A new relationship modality, (3) Sharing and socialisation and (4) Responsibilization. Finally, a premise and a corollary, respectively (5) Motivation and the (6) Circularity of the process, were identified. ConclusionOur study proposed a new theory of nursing students’ learning processes in clinical contexts during internships with COVID-19 patients. Despite significant difficulties, the nursing students developed a unique learning process characterised by motivation. Therefore, our study provided insight into the learning process during a pandemic and investigated the support needed for nursing students to continue their internships.
