Legal immigrants: invasion of alien microbial communities during winter occurring desert dust storms

Background A critical aspect regarding the global dispersion of pathogenic microorganisms is associated with atmospheric movement of soil particles. Especially, desert dust storms can transport alien microorganisms over continental scales and can deposit them in sensitive sink habitats. In winter 2014, the largest ever recorded Saharan dust event in Italy was efficiently deposited on the Dolomite Alps and was sealed between dust-free snow. This provided us the unique opportunity to overcome difficulties in separating dust associated from “domestic” microbes and thus, to determine with high precision microorganisms transported exclusively by desert dust. Results Our metagenomic analysis revealed that sandstorms can move not only fractions but rather large parts of entire microbial communities far away from their area of origin and that this microbiota contains several of the most stress-resistant organisms on Earth, including highly destructive fungal and bacterial pathogens. In particular, we provide first evidence that winter-occurring dust depositions can favor a rapid microbial contamination of sensitive sink habitats after snowmelt. Conclusions Airborne microbial depositions accompanying extreme meteorological events represent a realistic threat for ecosystem and public health. Therefore, monitoring the spread and persistence of storm-travelling alien microbes is a priority while considering future trajectories of climatic anomalies as well as anthropogenically driven changes in land use in the source regions

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%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) 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%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) 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; p < 0.0001). 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

Evaluation of Clinical Outcomes After Revascularization in Patients With Chronic Limb-Threatening Ischemia: Results From a Prospective National Cohort Study (RIVALUTANDO)

We evaluated the outcomes of revascularization in patients with chronic limb-threatening ischemia (CLTI) treated in real-world settings. This is a prospective multicenter cohort study with 12-month follow-up enrolling patients (n = 287) with CLTI undergoing open, endovascular, or hybrid lower extremity revascularization. The primary end point was amputation-free survival (AFS) at 12 months. Cox proportional analysis was used to determine independent predictors of amputation and restenosis. At 30 days, major adverse cardiovascular and major adverse limb events (MALE) rates were 3.1% and 2.1%, respectively. At 1 year, the overall survival rate was 88.8%, the AFS was 86.6%, and the primary patency was 70.5%. Freedom from MALE was 62.5%. After multivariate analysis, smoking (hazard ratio [HR] = 2.2, P = 0.04), renal failure (HR = 2.3, P = 0.03), Rutherford class ( 655) (HR = 3.2, P = 0.01), and below-the-knee disease (HR = 2.0, P = 0.05) were significant predictors of amputation; iloprost infusion (>10 vials) (HR = 0.64, P = 0.05) was a significant protective factor. Cilostazol administration (HR = 0.77, P = 0.05) was a significant protective factor for restenosis. Results from this prospective multicenter registry offer a consistent overview of clinical outcomes of CLTI patients at 1 year when adequately revascularized. Medical treatment, including statins, cilostazol and iloprost, were associated with improved 1-year freedom from restenosis and amputation

La metadatazione: cos’è?

Metadating, in the field of librarianship, is the dimension assumed by cataloging in the digital age; like cataloging, it refers to the process of recording metadata, that is, data functional to the identification and discovery of a bibliographic resource. It has been a reality for at least fifteen years in the international library context, especially in Northern Europe, the United States, Canada and Australia. With metadata, all relevant data continues to be recorded in an open environment – preferably according to cataloging rules suitable for metadata. What changes is the presentation, i.e., the way the created data is returned to the reader. Italian librarians and professors of librarianship answer 10 questions, offering, for the first time in an Italian journal, an overview of the topic of great interest in the international librarianship scene
