Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both
Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPDâ+âHF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPDâ+âHF. Patients with COPDâ+âHF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPDâ+âHF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPDâ+âHF for all causes (pâ=â0.010), respiratory causes (pâ=â0.006), cardiovascular causes (pâ=â0.046) and respiratory plus cardiovascular causes (pâ=â0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population
Disease-Modifying Therapies and Coronavirus Disease 2019 Severity in Multiple Sclerosis
Objective: This study was undertaken to assess the impact of immunosuppressive and immunomodulatory therapies on the severity of coronavirus disease 2019 (COVID-19) in people with multiple sclerosis (PwMS).
Methods: We retrospectively collected data of PwMS with suspected or confirmed COVID-19. All the patients had complete follow-up to death or recovery. Severe COVID-19 was defined by a 3-level variable: mild disease not requiring hospitalization versus pneumonia or hospitalization versus intensive care unit (ICU) admission or death. We evaluated baseline characteristics and MS therapies associated with severe COVID-19 by multivariate and propensity score (PS)-weighted ordinal logistic models. Sensitivity analyses were run to confirm the results.
Results: Of 844 PwMS with suspected (n = 565) or confirmed (n = 279) COVID-19, 13 (1.54%) died; 11 of them were in a progressive MS phase, and 8 were without any therapy. Thirty-eight (4.5%) were admitted to an ICU; 99 (11.7%) had radiologically documented pneumonia; 96 (11.4%) were hospitalized. After adjusting for region, age, sex, progressive MS course, Expanded Disability Status Scale, disease duration, body mass index, comorbidities, and recent methylprednisolone use, therapy with an anti-CD20 agent (ocrelizumab or rituximab) was significantly associated (odds ratio [OR] = 2.37, 95% confidence interval [CI] = 1.18-4.74, p = 0.015) with increased risk of severe COVID-19. Recent use (<1 month) of methylprednisolone was also associated with a worse outcome (OR = 5.24, 95% CI = 2.20-12.53, p = 0.001). Results were confirmed by the PS-weighted analysis and by all the sensitivity analyses.
Interpretation: This study showed an acceptable level of safety of therapies with a broad array of mechanisms of action. However, some specific elements of risk emerged. These will need to be considered while the COVID-19 pandemic persists
How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons
COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; pâ<â0.0001) and diagnostic evaluations (16.4% vs. 42.2%; pâ<â0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; pâ<â0.0001) or urgent (20.4% vs. 38.5%; pâ<â0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; pâ<â0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice
The effects of the neighboring landscape patterns, park history and local management on taxonomic and functional Collembola communities in soils of Mediterranean urban parks : Naples (Italy) and Montpellier (France) study cases
Lâurbanisation aboutit Ă une grande diversitĂ© environnementale, paysagĂšre, historique des espaces verts en ville, avec Ă©galement des pratiques de gestion trĂšs variĂ©es, qui, peuvent affecter la biodiversitĂ© quâils abritent.

A clear abiotic gradient was observed. By contrast, functional responses of Collembola communities to brushwood management intensification contradicted our research hypothesis based on the recent literature. Thus, it seems that brushwood removal does not cause shifts in species trait patterns in urban parks.This PhD work increased fundamental knowledge on urban park Collembola ecology, and it strives to integrate these findings in a more suitable landscaping and management of urban green spaces

Relationships between Quercus ilex L. litter characteristics and soil microarthropod community in an urban environment at different climatic conditions
In urban environments, climatic conditions and air pollution affect metal content, morphology and
physiology of leaves with implications for litter morphology and palatability affecting structural and
functional diversity of the soil microarthropod community. As leaf morphology rapidly responds to
different environmental factors, recently, functional leaf traits are considered good indicators of plant
health status. Aim of the research was to relate Quercus ilex (good monitor of air pollution) leaf, litter and soil microarthropod community characteristics taking into account metal pollution and climatic
conditions. The research was performed in an urban environment of the Mediterranean area. Leaves an
litter were characterized for Cd, Cr, Cu, Ni and Pb concentrations and for the main functional traits. The
soil microarthropod community was investigated for abundance and richness as well as for habitat and
diet preferences. The main results were that leaf metal accumulation and climatic condition contextuall
affected the litter characteristics both in terms of metal composition and morphological traits. Litter
quality discriminated different microarthropod taxa assemblages according trophic preferences whereas climatic conditions strongly affected microarthropod habitat distribution
Spatial patterns and scales of Collembola taxonomic and functional diversity in urban parks
Anthropogenic pressures can affect the distribution of species and elicit the appearance of spatial patterns that provide insights into the speciesâ responses to environmental ïŹltering, mediated by their functional traits. Due to the functional redundancy in ecological communities, the spatial variations of species and functional traits can occur at different scales, but little is known on this topic, especially for soil arthropods with limited dispersion capabilities and highly dependent on environmental characteristics. The present research aims at shedding light on the spatial ecology of both the taxonomic and functional biodiversity of collembolan communities colonizing urban parks, adopted as model taxa for their functional traits, diversity and sensitivity to environmental drivers. To this end, the spatial patterns and scales of collembolan communities from 8 parks in Naples (Italy) and 14 in Montpellier (France) were investigated through an approach based on Moran eigenvector maps, modiïŹed to allow for evaluating the community spatial connectivity and the scales underpinning the spatial variation of each species and functional trait. The obtained ïŹndings demonstrate a limited spatial connectivity of collembolan communities in terms of both taxonomic and functional diversity, with mostly species-speciïŹc micro-scale variations that may be shaped by environmental constraints
