Patient safety subcultures among nursing home staff in Italy: a cross-sectional study

Nursing home (NH) residents are vulnerable subjects and highly susceptible to adverse events. Knowledge of patient safety culture (PSC) is essential for an organization to ensure patient safety. However, research on PSC in NHs, and its variability among staff, is still scarce. This study aimed to explore whether and how PSC differed among NH staff (Managers, Nurses, Direct Care Staff, Support Staff, Administrative Staff and Other Providers) in the Autonomous Province of Trento, Italy. This study employed a cross-sectional design and collected data from 1145 NH providers using the Nursing Home Survey on Patient Safety Culture (NHSPSC). Data were analyzed using linear mixed models, with each of the 12 NHSPSC domains as a response variable. The majority of the respondents (61.6%) were Direct Care Staff members. ‘Feedback and Communication about Incidents’ and ‘Overall Perceptions of Resident Safety’ were the domains with the highest proportions of positive answers (PPAs). For most staff categories, ‘Staffing’ was the domain with the lowest PPA. Support Staff showed significantly lower scores in the majority of domains (8/12). Shorter job tenure, fewer weekly working hours, working mostly during the day and working in highly specialized areas were associated with higher scores in several domains. Interventions to improve PSC must consider the differences between professional groups. Further research is needed to explore the relationship between job-related features and perceptions of patient safety among NH workers

Intensity of medical care in internal medicine: impact on outcomes from a trend analysis over six years

In large acute medical wards treating heterogenous and complex patients intensity of patient care should be graduated according to clinical severity. We conducted a retrospective observational study on all unselected admissions (8838) to the internal medicine ward of the Santa Chiara Hospital of Trento from 2012 to 2017. During 2012 and 2013, a standard organizational model (SMC) was in place, while an organizational model for intensity of medical care (IMC) was introduced in 2014. In SMC, patient admission was performed according to bed availability only. In IMC, patients were allocated to three different ward settings (high, medium and post-acute care) based on the stratification of clinical instability. The National Early Warning Score (NEWS) was used for the stratification, together with the clinical judgment. The implementation of the IMC model led to a decrease of mortality and urgent transfers for clinical deterioration to Intensive Care Unit and to an increase of admissions from Intensive Care Unit and from regional spoke hospitals. Redesigning delivery processes based on IMC can play a pivotal role in improving patient outcomes and bed management

Plasma concentration of presepsin and its relationship to the diagnosis of infections in multiple trauma patients admitted to intensive care

Background and aims: Septic complications represent the pre- dominant cause of late death in poly-trauma patients. The necessi- ty to differentiate septic from non septic patients is more relevant at the early stage of the illness in order to improve the clinical out- come and to reduce the mortality. The identification of a sensitive and specific, clinically reliable, biomarker capable to early recog- nize incoming septic complications in trauma patients whose expression is not influenced by concomitant traumatic injuries, is still a challenge for the researchers in the field. patients (9 females and 39 males, mean age 47.6\ub119 years) with mul- tiple trauma was performed. The inclusion criterion was to suffer from acute trauma since no more than 24 hours and the exclusion cri- teria were the following: antibiotic treatment on admission and main- tained for more than 48 hours; on-going infection on admission not associated with trauma; treatment with immunosuppressors/ immunomodulants; age <18 years old. Presepsin was measured using an automated chemiluminescence analyser at 1, 3, 5 and 8 days post of hospitalization. The diagnosis of systemic inflammatory response syndrome (SIRS)/infection was established according to the criteria of the Surviving Sepsis Campaign. Materials and methods: A retrospective analysis on 48 adult Results and conclusions: In patients with SIRS, the mean pre- sepsin concentration was 917,08 (\ub169.042) ng/L vs 980,258 (\ub11951.32) ng/L in patients without SIRS (P=0.769). In the infected patients, the mean presepsin concentration was 1513.25 (\ub12296.54) ng/L vs 654.21 (\ub1511,068) ng/L (P<0.05) calculated among the non infected upon admission. The plasma presepsin concentration increased progressively during the first 8 days of hospitalization. Presepsin concentration in the infected patients was significantly higher than in non-infected patients. On the other hands no signifi- cant differences were found in the plasma level of presepsin among patients with and without SIRS. Any other clinical condition related to the trauma did not affect presepsin. Our data clearly suggest that presepsin may be considered an helpful diagnostic tool to early diagnose sepsis in trauma patients

OltreMare - Un progetto per il futuro della Biodiversità del Mediterraneo

Osservatorio e comunicazione. Questo progetto narra dello sguardo degli artisti dell’Accademia di Belle Arti di Palermo sul lavoro di ricerca portato avanti dall’IAS - CNR (ex IAMC) riguardo all’osservazione e alla tutela della Biodiversità e costituisce uno strumento eccellente di comunicazione per un pubblico quanto mai ampio. La divulgazione della scienza è un’attività complessa e sicuramente necessita di competenze e attitudini multidisciplinari oltreché di motivazione ed entusiasmo. La comunicazione delle tematiche scientifiche, di per sè ostiche nella traduzione al grande pubblico, grazie alla forza e all’immediatezza tipica dell’espressione artistica diventa prodigioso spunto di riflessione e di osservazione, sia per i giovani che per la comunità intera. Grazie al progetto Osservatorio della Biodiversità Siciliana, sono state realizzate da partners con competenze istituzionali complementari , quali l’Accademia di Belle Arti di Palermo e l’IAS - CNR di Capo Granitola, delle azioni didattiche e creative di valore scientifico espresse con straordinaria forza e bellezza. La sinergia creata, nata da un rapporto consolidato ormai da tempo, ha portato ad uno scambio tra ricercatori e professori che si sono messi in gioco in uno sforzo congiunto per avvicinare le proprie competenze. In seguito ad un’intensa attività di coordinamento e pianificazione dei lavori, si è riusciti a portare avanti un progetto ambizioso e imponente, coinvolgendo moltissimi ambiti scientifici e altrettante cattedre, sensibilizzando così gli artisti ai temi della Biodiversità. Le opere prodotte, accompagnate da schede scientifiche, hanno dunque acquisito un valore, oltreché artistico, didattico, e restano come testimonianze oggettive, nel percorso culturale, per i visitatori dell’Osservatorio. Questa collaborazione conferma l’importanza e l’opportunità di unire arte e scienza per esaltare la percezione della ricerca scientifica da parte della comunità e ,ancora una volta, si conferma come, per fare “cose straordinarie”, siano più importanti i rapporti umani piuttosto che le competenze tecniche. A tal proposito, un ringraziamento sentito al Prof. Calogero Piro che, con passione e dedizione, ha reso possibile questa esperienza, e al gruppo di Comunicazione EDU Lab dell’IAS - CNR, che è stato, per me, un supporto indispensabile per la realizzazione di questo complesso progetto

Optimizing the “Time to pregnancy” in women with multiple sclerosis: the OPTIMUS Delphi survey

BackgroundThe debate on how to manage women affected by multiple sclerosis (MS) during reproductive age is still open, as is the issue of fertility in such patients. Main issue regard the identification of the optimal window for pregnancy and how to deal with medical therapy before and during conception. The aim of this Delphi consensus was to collect the opinions of a multidisciplinary group, involving reproductive medicine specialists and neurologists with experience in the management of multiple sclerosis women with reproductive desire.MethodsFour experts plus scientific coordinators developed a questionnaire distributed online to 10 neurologists and later discussed the responses and amended a list of statements. The statements were then distributed via an online survey to 23 neurologists (comprising the first 10), who voted on their level of agreement/disagreement with each statement. Consensus was achieved if agreement or disagreement with a statement exceeded 66%.ResultsTwenty-one statements reached consensus after two rounds of voting, leading to the following main recommendations: (1) Fertility evaluation should be suggested to wMS, in case of the need to shorten time to pregnancy and before treatment switch in women on DMTs contraindicated in pregnancy, particularly in case of highly active disease and age > 35 years. (2) ART should not be discouraged in wMS, but the use of DMTs until pregnancy confirmation should be suggested; ART may be considered in order to reduce time to pregnancy in MS women with a reduced ovarian reserve and/or age > 35 years, but in case of an expected poor ART prognosis and the need for more than one ART cycle, a switch to a high-efficacy DMD before ART should be offered. (3) Oocyte cryopreservation may be considered in women with reduced ovarian reserve, with unpredictable time to complete diagnostic workup and achieve disease control; a risk/cost–benefit analysis must be performed in women >35 years, considering the diminished ovarian reserve.ConclusionThis consensus will help MS neurologists to support family planning in wMS, respecting MS therapeutic needs while also taking into account the safety and impact of advancing age on fertility

COVID-19 Severity in Multiple Sclerosis: Putting Data Into Context

Background and objectives: It is unclear how multiple sclerosis (MS) affects the severity of COVID-19. The aim of this study is to compare COVID-19-related outcomes collected in an Italian cohort of patients with MS with the outcomes expected in the age- and sex-matched Italian population. Methods: Hospitalization, intensive care unit (ICU) admission, and death after COVID-19 diagnosis of 1,362 patients with MS were compared with the age- and sex-matched Italian population in a retrospective observational case-cohort study with population-based control. The observed vs the expected events were compared in the whole MS cohort and in different subgroups (higher risk: Expanded Disability Status Scale [EDSS] score > 3 or at least 1 comorbidity, lower risk: EDSS score ≤ 3 and no comorbidities) by the χ2 test, and the risk excess was quantified by risk ratios (RRs). Results: The risk of severe events was about twice the risk in the age- and sex-matched Italian population: RR = 2.12 for hospitalization (p < 0.001), RR = 2.19 for ICU admission (p < 0.001), and RR = 2.43 for death (p < 0.001). The excess of risk was confined to the higher-risk group (n = 553). In lower-risk patients (n = 809), the rate of events was close to that of the Italian age- and sex-matched population (RR = 1.12 for hospitalization, RR = 1.52 for ICU admission, and RR = 1.19 for death). In the lower-risk group, an increased hospitalization risk was detected in patients on anti-CD20 (RR = 3.03, p = 0.005), whereas a decrease was detected in patients on interferon (0 observed vs 4 expected events, p = 0.04). Discussion: Overall, the MS cohort had a risk of severe events that is twice the risk than the age- and sex-matched Italian population. This excess of risk is mainly explained by the EDSS score and comorbidities, whereas a residual increase of hospitalization risk was observed in patients on anti-CD20 therapies and a decrease in people on interferon

DMTs and Covid-19 severity in MS: a pooled analysis from Italy and France

We evaluated the effect of DMTs on Covid-19 severity in patients with MS, with a pooled-analysis of two large cohorts from Italy and France. The association of baseline characteristics and DMTs with Covid-19 severity was assessed by multivariate ordinal-logistic models and pooled by a fixed-effect meta-analysis. 1066 patients with MS from Italy and 721 from France were included. In the multivariate model, anti-CD20 therapies were significantly associated (OR = 2.05, 95%CI = 1.39–3.02, p < 0.001) with Covid-19 severity, whereas interferon indicated a decreased risk (OR = 0.42, 95%CI = 0.18–0.99, p = 0.047). This pooled-analysis confirms an increased risk of severe Covid-19 in patients on anti-CD20 therapies and supports the protective role of interferon

Cayley continuants

AbstractIn 1858 Cayley considered a particular kind of tridiagonal determinants (or continuants). By a direct inspection of the first cases, he conjectured an identity expressing these determinants in terms of certain other determinants considered by Sylvester in 1854. Then Cayley proved the conjectured identity by induction but, as he wrote, he felt unsatisfied with his proof. The main aim of this paper is to give a straightforward proof of Cayley's identity using the method of formal series. Moreover we use this method and umbral calculus techniques to obtain several other identities.Cayley continuants appear in several contexts and in particular in enumerative combinatorics. Mittag–Leffler polynomials, Meixner polynomials of the first kind, the falling and the raising factorials are just few instances of these continuants. They can be interpreted in terms of weighted permutations. Moreover, as we prove in this paper, they also appear in the context of Hankel determinants generated by certain Catalan-like numbers
