Il viaggio delle forme. Migrazione di maestri e modelli nella scultura barocca tra Roma e la Lombardia.

Il presente contributo approfondisce la circolazione e la diffusione di alcuni modelli compositivi elaborati a Roma entro la metà del Seicento nella scultura lombarda del XVII e XVIII secolo. Gli esempi proposti appartengono al circuito di scultori gravitanti intorno allo studio di Ercole Ferrata, le cui opere ebbero larga diffusione presso le generazioni successive grazie ai lasciti a accademie e allievi. In particolare il gruppo di statue lignee oggi al Museo Diocesano di Scaria Intelvi offre la possibilità di verificare i termini di questa diffusione. Tra i maestri lombardi del Settecento che si avvalsero di questi modelli figurano Giuseppe Rusnati, la cui raccolta di exempla è documentata da un inventario post mortem e subito dopo Giuseppe Antignati, scultore attivo su tutto il territorio regionale.This paper explores the circulation and spread of certain compositional models developed in Rome bythe mid-Seventeenth century in Lombard sculpture of the Seventeenth and Eighteenth centuries. Theexamples belong to sculptors gravitating around Ercole Ferrata's workshop, whose works were widelyknown by the following generations due to the legacies he made to academies and students. Inparticular, a group of wooden statues now in the Museo Diocesano in Scaria Intelvi offers thepossibility to check the terms of this spread. Giuseppe Rusnati, whose collection of exempla isdocumented by a post-mortem inventory and Giuseppe Antignati, sculptor active across the entireregion, are among the Eighteenth century Lombard masters who used these models

Archivi per l’impresa, archivi per la storia: esplorazioni nel fondo delle Filande e Tessiture Costa dell’Archivio di Stato di Como

Il contributo mira a presentare i primi risultati di un’indagine storica sulla produzione tessile e serica a Como nel Novecento. Esso si concentra in modo particolare sullo studio degli archivi delle imprese e delle aziende impegnate in questo specifico settore della produzione industriale a Como e nel suo distretto economico. Gli archivi delle imprese permettono di indagare le modalità organizzative dei processi produttivi e nel caso della industria della seta di verificare i modi di divisione del lavoro tra i reparti esecutivi e quelli creativi. L’industria tessile, soprattutto nel secondo dopoguerra, incrocia le vicende dell’industria della moda e la congiuntura sollecita una riflessione sui rapporti tra stilisti, disegnatori, produttori. L’esempio principale sui cui si imposta il contributo è offerto dall’archivio delle Filande e Tessiture Costa, che hanno cessato l’attività ma che ebbero importanti collaborazioni con maisons di moda come Dior, Gicenchy, Max Mara etc. Il fondo è stato acquisito dall’Archivio di Stato di Como ed è interamente consultabile, ma in attesa di catalogazione e valorizzazione. In questa occasione se ne ricorda l’importanza come bene storico e come documento della ricaduta nei processi produttivi e delle organizzazioni aziendali sulla costruzione di valori sociali e culturali nel territorio

Métodos de determinação de períodos: testes comparativos para a estrela AV Cir

O objetivo deste projeto é definir o método mais eficiente na determinação de periodicidades em séries temporais desigualmente espaçadas, para faixas de períodos de um a seis dias. A escassez de métodos numéricos eficientes destinados ao tratamento destas séries, é devido em grande parte, à sua complexidade, que torna difícil o seu controle e previsão. Estas séries, ao contrário das igualmente espaçadas, não podem ser modeladas pela teoria estatística convencional, exigindo técnicas particulares para a obtenção de resultados significativos. Procuramos generalizar as características das técnicas mais populares e comparar seus desempenhos através da utilização de séries temporais artificiais com diversos níveis de relação sinal-ruído, que simulam características de observações astronômicas reais. Finalmente, discutimos a aplicação dos métodos em uma série real da estrela variável AV Cir e suas implicações

Efficacy of a new technique - INtubate-RECruit-SURfactant-Extubate - "IN-REC-SUR-E" - in preterm neonates with respiratory distress syndrome: Study protocol for a randomized controlled trial

Background: Although beneficial in clinical practice, the INtubate-SURfactant-Extubate (IN-SUR-E) method is not successful in all preterm neonates with respiratory distress syndrome, with a reported failure rate ranging from 19 to 69 %. One of the possible mechanisms responsible for the unsuccessful IN-SUR-E method, requiring subsequent re-intubation and mechanical ventilation, is the inability of the preterm lung to achieve and maintain an "optimal" functional residual capacity. The importance of lung recruitment before surfactant administration has been demonstrated in animal studies showing that recruitment leads to a more homogeneous surfactant distribution within the lungs. Therefore, the aim of this study is to compare the application of a recruitment maneuver using the high-frequency oscillatory ventilation (HFOV) modality just before the surfactant administration followed by rapid extubation (INtubate-RECruit-SURfactant-Extubate: IN-REC-SUR-E) with IN-SUR-E alone in spontaneously breathing preterm infants requiring nasal continuous positive airway pressure (nCPAP) as initial respiratory support and reaching pre-defined CPAP failure criteria. Methods/design: In this study, 206 spontaneously breathing infants born at 24+0-27+6 weeks' gestation and failing nCPAP during the first 24 h of life, will be randomized to receive an HFOV recruitment maneuver (IN-REC-SUR-E) or no recruitment maneuver (IN-SUR-E) just prior to surfactant administration followed by prompt extubation. The primary outcome is the need for mechanical ventilation within the first 3 days of life. Infants in both groups will be considered to have reached the primary outcome when they are not extubated within 30 min after surfactant administration or when they meet the nCPAP failure criteria after extubation. Discussion: From all available data no definitive evidence exists about a positive effect of recruitment before surfactant instillation, but a rationale exists for testing the following hypothesis: a lung recruitment maneuver performed with a step-by-step Continuous Distending Pressure increase during High-Frequency Oscillatory Ventilation (and not with a sustained inflation) could have a positive effects in terms of improved surfactant distribution and consequent its major efficacy in preterm newborns with respiratory distress syndrome. This represents our challenge. Trial registration: ClinicalTrials.gov identifier: NCT02482766. Registered on 1 June 2015

First molecular identification of the zoonotic parasite Anisakis pegreffii (Nematoda: Anisakidae) in a paraffin-embedded granuloma taken from a case of human intestinal anisakiasis in Italy

<p>Abstract</p> <p>Background</p> <p>Anisakiasis is an important fish-borne zoonosis provoked by larval stages of nematodes belonging to the genus <it>Anisakis</it>. The detection and identification of human infections is difficult. This is due to: a) the low specificity of the clinical features and symptomatology related to human infections; b) the paucity of diagnostic features of larvae found in granulomatous lesions characteristic of "invasive anisakiasis"; and c) the lack morphological characters diagnostic at the specific level when larvae of <it>Anisakis </it>are detected. Thus, molecular-based diagnostic approaches are warranted.</p> <p>Method</p> <p>We have developed a PCR method that amplifies the DNA of <it>Anisakis </it>spp. in fixed paraffin-embedded tissues. This method was applied to a granuloma removed from a human case of intestinal anisakiasis in Italy. Specific primers of the mtDNA <it>cox2 </it>gene were used and sequence analysis was performed according to the procedures already established for species of <it>Anisakis</it>.</p> <p>Results</p> <p>The sequence obtained (629 bp) was compared with those of the other species of <it>Anisakis </it>which have so far been genetically characterized and with sequences obtained from larval stages of <it>Anisakis </it>collected from the Mediterranean fish <it>Engraulis encrasicolus</it>. This enabled the genetic identification of the larva in the human tissue as <it>A. pegreffii</it>. This is the first instance of human intestinal anisakiasis diagnosed using PCR of DNA purified from a fixed eosinophilic granuloma embedded in paraffin.</p> <p>Conclusion</p> <p>The case of human anisakiasis presented reinforces the pathological significance of the species <it>A. pegreffii </it>to humans. The molecular/genetic methodological approach based on mtDNA <it>cox2 </it>sequence analysis, described here, can allow easy and rapid identification of <it>Anisakis </it>spp. in formalin-fixed and paraffin embedded tissues removed from cases of either gastric or intestinal human anisakiasis.</p

Comparison and combination of a hemodynamics/biomarkers-based model with simplified PESI score for prognostic stratification of acute pulmonary embolism: findings from a real world study

Background: Prognostic stratification is of utmost importance for management of acute Pulmonary Embolism (PE) in clinical practice. Many prognostic models have been proposed, but which is the best prognosticator in real life remains unclear. The aim of our study was to compare and combine the predictive values of the hemodynamics/biomarkers based prognostic model proposed by European Society of Cardiology (ESC) in 2008 and simplified PESI score (sPESI).Methods: Data records of 452 patients discharged for acute PE from Internal Medicine wards of Tuscany (Italy) were analysed. The ESC model and sPESI were retrospectively calculated and compared by using Areas under Receiver Operating Characteristics (ROC) Curves (AUCs) and finally the combination of the two models was tested in hemodinamically stable patients. All cause and PE-related in-hospital mortality and fatal or major bleedings were the analyzed endpointsResults: All cause in-hospital mortality was 25% (16.6% PE related) in high risk, 8.7% (4.7%) in intermediate risk and 3.8% (1.2%) in low risk patients according to ESC model. All cause in-hospital mortality was 10.95% (5.75% PE related) in patients with sPESI score ≥1 and 0% (0%) in sPESI score 0. Predictive performance of sPESI was not significantly different compared with 2008 ESC model both for all cause (AUC sPESI 0.711, 95% CI: 0.661-0.758 versus ESC 0.619, 95% CI: 0.567-0.670, difference between AUCs 0.0916, p=0.084) and for PE-related mortality (AUC sPESI 0.764, 95% CI: 0.717-0.808 versus ESC 0.650, 95% CI: 0.598-0.700, difference between AUCs 0.114, p=0.11). Fatal or major bleedings occurred in 4.30% of high risk, 1.60% of intermediate risk and 2.50% of low risk patients according to 2008 ESC model, whereas these occurred in 1.80% of high risk and 1.45% of low risk patients according to sPESI, respectively. Predictive performance for fatal or major bleeding between two models was not significantly different (AUC sPESI 0.658, 95% CI: 0.606-0.707 versus ESC 0.512, 95% CI: 0.459-0.565, difference between AUCs 0.145, p=0.34). In hemodynamically stable patients, the combined endpoint in-hospital PE-related mortality and/or fatal or major bleeding (adverse events) occurred in 0% of patients with low risk ESC model and sPESI score 0, whilst it occurred in 5.5% of patients with low-risk ESC model but sPESI ≥1. In intermediate risk patients according to ESC model, adverse events occurred in 3.6% of patients with sPESI score 0 and 6.65% of patients with sPESI score ≥1.Conclusions: In real world, predictive performance of sPESI and the hemodynamic/biomarkers-based ESC model as prognosticator of in-hospital mortality and bleedings is similar. Combination of sPESI 0 with low risk ESC model may identify patients with very low risk of adverse events and candidate for early hospital discharge or home treatment.

Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy

IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P &lt; .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
