Increased cancer risk in patients undergoing dialysis: a population-based cohort study in North-Eastern Italy

open116noBACKGROUND: In southern Europe, the risk of cancer in patients with end-stage kidney disease receiving dialysis has not been well quantified. The aim of this study was to assess the overall pattern of risk for de novo malignancies (DNMs) among dialysis patients in the Friuli Venezia Giulia region, north-eastern Italy. METHODS: A population-based cohort study among 3407 dialysis patients was conducted through a record linkage between local healthcare databases and the cancer registry (1998-2013). Person-years (PYs) were calculated from 30 days after the date of first dialysis to the date of DNM diagnosis, kidney transplant, death, last follow-up or December 31, 2013, whichever came first. The risk of DNM, as compared to the general population, was estimated using standardized incidence ratios (SIRs) and 95% confidence intervals (CIs). RESULTS: During 10,798 PYs, 357 DNMs were diagnosed in 330 dialysis patients. A higher than expected risk of 1.3-fold was found for all DNMs combined (95% CI: 1.15-1.43). The risk was particularly high in younger dialysis patients (SIR = 1.88, 95% CI: 1.42-2.45 for age 40-59 years), and it decreased with age. Moreover, significantly increased DNM risks emerged during the first 3 years since dialysis initiation, especially within the first year (SIR = 8.52, 95% CI: 6.89-10.41). Elevated excess risks were observed for kidney (SIR = 3.18; 95% CI: 2.06-4.69), skin non-melanoma (SIR = 1.81, 95% CI: 1.46-2.22), oral cavity (SIR = 2.42, 95% CI: 1.36-4.00), and Kaposi's sarcoma (SIR = 10.29, 95% CI: 1.25-37.16). CONCLUSIONS: The elevated risk for DNM herein documented suggest the need to implement a targeted approach to cancer prevention and control in dialysis patients.openTaborelli, Martina; Toffolutti, Federica; Del Zotto, Stefania; Clagnan, Elena; Furian, Lucrezia; Piselli, Pierluca; Citterio, Franco; Zanier, Loris; Boscutti, Giuliano; Serraino, Diego for the Italian Transplant & Cancer Cohort Study; Sarah Shalaby, Raffaella Petrara, Patrizia Burra, Giacomo Zanus, Stefano Zanini,Paolo Rigotti; Maria Rendina, AlfredoDi Leo, Francesco Paolo Schena, Giuseppe Grandaliano, Marco Fiorentino, Augusto Lauro, Antonio Daniele Pinna, PaoloDi Gioia, Sara Pellegrini, Chiara Zanfi, Maria Piera Scolari, Sergio Stefoni, PaolaTodeschini, Laura Panicali, Chiara Valentini, Umberto Baccarani, Andrea Risaliti, Gian Luigi Adani, Dario Lorenzin, Giuseppe Maria Ettorre, Giovanni Vennarecci,Marco Colasanti, Manuela Coco, Fabrizio Ettorre, Roberto Santoro, LuciaMiglioresi, Francesco Nudo, Massimo Rossi,Gianluca Mennini, Luca Toti, GiuseppeTisone, Annachiara Casella, Laura Fazzolari, Daniele Sforza, Giuseppe Iaria,Carlo Gazia, Chiara Belardi, ClaudiaCimaglia, Alessandro Agresta, Gianpiero D’Offizi, Ubaldo Visco Comandini,Raffaella Lionetti, Marzia Montalbano, Chiara Taibi, Giovanni Fantola, Fausto Zamboni, Gian Benedetto Piredda,Maria Benigna Michittu, Maria Gavina Murgia, Bruno Onano, Lucia Fratino, Luigino Dal Maso, Paolo De Paoli, Diana Verdirosi,Emanuela Vaccher, Francesco Pisani, Antonio Famulari, Federica Delreno, Samuele Iesari, LindaDe Luca, Maurizio Iaria, Enzo Capocasale,Elena Cremaschi, Silvio Sandrini, Francesca Valerio,Valentina Mazzucotelli, Nicola Bossini, Gisella Setti, Massimiliano Veroux, Pierfrancesco Veroux, Giuseppe Giuffrida,Alessia Giaquinta, Domenico Zerbo, GhilBusnach, Laura Di Leo, Maria Luisa Perrino, Marialuisa Querques, ValerianaColombo, Maria Chiara Sghirlanzoni , Piergiorgio Messa, Antonio Leoni , Laura Galatioto, Salvatore Gruttadauria, Vito Sparacino, FlaviaCaputo, Barbara Buscemi ,Franco Cit-terio, Gionata Spagnoletti, Maria Paola Salerno, Evaldo Favi Giuseppe Paolo Segoloni, Luigi Biancone, AntonioLavacca, Maria Cristina Maresca, CarmeloCascone, Bice Virgilio, Donato Donati, Fiorella Dossi, Andrea Fontanella, Andrea Ambrosini, Marco Di CiccoTaborelli, Martina; Toffolutti, Federica; Del Zotto, Stefania; Clagnan, Elena; Furian, Lucrezia; Piselli, Pierluca; Citterio, Franco; Zanier, Loris; Boscutti, Giuliano; Serraino, Diego for the Italian Transplant & Cancer Cohort Study; Shalaby, Sarah; Petrara, MARIA RAFFAELLA; Burra, Patrizia; Zanus, Giacomo; Zanini, Stefano; Rigotti, Paolo; Maria, Rendina; Alfredodi, Leo; Francesco Paolo Schena, ; Giuseppe, Grandaliano; Marco, Fiorentino; Augusto, Lauro; Antonio Daniele Pinna, ; Paolodi, Gioia; Sara, Pellegrini; Chiara, Zanfi; Maria Piera Scolari, ; Sergio, Stefoni; Paolatodeschini, ; Laura, Panicali; Chiara, Valentini; Umberto, Baccarani; Andrea, Risaliti; Gian Luigi Adani, ; Dario, Lorenzin; Giuseppe Maria Ettorre, ; Giovanni, Vennarecci; Marco, Colasanti; Manuela, Coco; Fabrizio, Ettorre; Roberto, Santoro; Luciamiglioresi, ; Francesco, Nudo; Massimo, Rossi; Gianluca, Mennini; Luca, Toti; Giuseppetisone, ; Annachiara, Casella; Laura, Fazzolari; Daniele, Sforza; Giuseppe, Iaria; Carlo, Gazia; Chiara, Belardi; Claudiacimaglia, ; Alessandro, Agresta; Gianpiero, D’Offizi; Ubaldo Visco Comandini, ; Raffaella, Lionetti; Marzia, Montalbano; Chiara, Taibi; Giovanni, Fantola; Fausto, Zamboni; Gian Benedetto Piredda, ; Maria Benigna Michittu, ; Maria Gavina Murgia, ; Bruno, Onano; Lucia, Fratino; Luigino Dal Maso, ; Paolo De Paoli, ; Diana, Verdirosi; Emanuela, Vaccher; Francesco, Pisani; Antonio, Famulari; Federica, Delreno; Samuele, Iesari; Lindade, Luca; Maurizio, Iaria; Enzo, Capocasale; Elena, Cremaschi; Silvio, Sandrini; Francesca, Valerio; Valentina, Mazzucotelli; Nicola, Bossini; Gisella, Setti; Massimiliano, Veroux; Pierfrancesco, Veroux; Giuseppe, Giuffrida; Alessia, Giaquinta; Domenico, Zerbo; Ghilbusnach, ; Laura Di Leo, ; Maria Luisa Perrino, ; Marialuisa, Querques; Valerianacolombo, ; Maria Chiara Sghirlanzoni, ; Piergiorgio, Messa; Antonio, Leoni; Laura, Galatioto; Salvatore, Gruttadauria; Vito, Sparacino; Flaviacaputo, ; Barbara, Buscemi; Franco, Cit-terio; Gionata, Spagnoletti; Maria Paola Salerno, ; Evaldo Favi Giuseppe Paolo Segoloni, ; Luigi, Biancone; Antoniolavacca, ; Maria Cristina Maresca, ; Carmelocascone, ; Bice, Virgilio; Donato, Donati; Fiorella, Dossi; Andrea, Fontanella; Andrea, Ambrosini; Marco Di Cicco

Air pollutants and daily number of admissions to psychiatric emergency services: evidence for detrimental mental health effects of ozone

Abstract Aims Aim of the current study is to investigate the associations between daily levels of air pollutants (particulate matter, ozone, carbon monoxide, nitrogen dioxide) and daily admissions for mental disorders to the emergency department of two general hospitals in Umbria region (Italy). Methods We collected data about daily admissions to psychiatric emergency services of two general hospitals, air pollutants' levels and meteorological data for the time period 1 January 2015 until 31 December 2016. We assessed the impact of an increase in air pollutants on the number of daily admissions using a time-series econometric framework. Results A total of 1860 emergency department admissions for mental disorders were identified. We observed a statistically significant impact of ozone levels on daily admissions. The estimated coefficient of O3 is statistically significant at the 1% level. All other pollutants were not significantly associated with the number of daily admissions. Conclusions Short-term exposure to ozone may be associated with increased psychiatric emergency services admissions. Findings add to previous literature on existing evidence for air pollution to have an impact on mental health. Ozone may be considered a potential environmental risk factor for impaired mental health

Surgical site infection after caesarean section. Space for post-discharge surveillance improvements and reliable comparisons

Surgical site infections (SSI) after caesarean section (CS) represent a substantial health system concern. Surveying SSI has been associated with a reduction in SSI incidence. We report the findings of three (2008, 2011 and 2013) regional active SSI surveillances after CS in community hospital of the Latium region determining the incidence of SSI. Each CS was surveyed for SSI occurrence by trained staff up to 30 post-operative days, and association of SSI with relevant characteristics was assessed using binomial logistic regression. A total of 3,685 CS were included in the study. A complete 30 day post-operation follow-up was achieved in over 94% of procedures. Overall 145 SSI were observed (3.9% cumulative incidence) of which 131 (90.3%) were superficial and 14 (9.7%) complex (deep or organ/space) SSI; overall 129 SSI (of which 89.9% superficial) were diagnosed post-discharge. Only higher NNIS score was significantly associated with SSI occurrence in the regression analysis. Our work provides the first regional data on CS-associated SSI incidence, highlighting the need for a post-discharge surveillance which should assure 30 days post-operation to not miss data on complex SSI, as well as being less labour intensive

Frequency and duration of SARS-CoV-2 shedding in oral fluid samples assessed by a modified commercial rapid molecular assay

Background: RT-PCR on nasopharyngeal (NPS)/oropharyngeal swabs is the gold standard for diagnosis of SARS-CoV-2 infection and viral load monitoring. Oral fluid (OF) is an alternate clinical sample, easy and safer to collect and could be useful for COVID-19 diagnosis, monitoring viral load and shedding. Methods: Optimal assay conditions and analytical sensitivity were established for the commercial Simplexa™ COVID-19 Direct assay adapted to OF matrix. The assay was used to test 337 OF and NPS specimens collected in parallel from 164 hospitalized patients; 50 bronchoalveolar lavage (BAL) specimens from a subgroup of severe COVID-19 cases were also analysed. Results: Using Simplexa™ COVID-19 Direct on OF matrix, 100% analytical detection down to 1 TCID50/mL (corresponding to 4 × 103 copies (cp)/mL) was observed. No crossreaction with other viruses transmitted through the respiratory toute was observed. Parallel testing of 337 OF and NPS samples showed highly concordant results (κ = 0.831; 95 % CI = 0.771–0.891), and high correlation of Ct values (r = 0.921; p < 0.0001). High concordance and elevated correlation was observed also between OF and BAL. Prolonged viral RNA shedding was observed up to 100 days from symptoms onset (DSO), with 32% and 29% positivity observed in OF and NPS samples, respectively, collected between 60 and 100 DSO. Conclusions: Simplexa™ COVID-19 Direct assays on OF have high sensitivity and specificity to detect SARS-CoV-2 RNA and provide an alternative to NPS for diagnosis and monitoring SARS-CoV-2 shedding

Pulmonary Kaposi's sarcoma after heart transplantation: a case report

ABSTRACT: INTRODUCTION: Kaposi's sarcomas have been associated with different conditions of immunosuppression and are also known to be a typical complication of solid organ transplantations. CASE PRESENTATION: We report of a 65 year old man of Turkish origin with a history of heart transplantation 10 months ago who presented for clarification of his dyspnoea. The patient had a known history of chronic obstructive pulmonary disease and a smoking history of 40 pack years. Radiologically, three progressively growing intrapulmonary nodules were detected. The histology was diagnostic for a Kaposi's sarcoma. Visceral and especially primary intrapulmonary Kaposi's sarcomas are very rare and have been described to have a rather unfavourable prognosis. CONCLUSION: Even with a history suggestive for conventional lung cancer, Kaposi's sarcomas should be considered in patients after transplantation of solid organs. It should be noticed that in a minority of cases this tumour exists in the absence of the typical cutaneous lesions

Emulation of a Target Trial From Observational Data to Compare Effectiveness of Casirivimab/Imdevimab and Bamlanivimab/Etesevimab for Early Treatment of Non-Hospitalized Patients With COVID-19

OBJECTIVES: Comparative analysis between different monoclonal antibodies (mAbs) against SARS-CoV-2 are lacking. We present an emulation trial from observational data to compare effectiveness of Bamlanivimab/Etesevimab (BAM/ETE) and Casirivimab/Imdevimab (CAS/IMD) in outpatients with early mild-to-moderate COVID-19 in a real-world scenario of variants of concern (VoCs) from Alpha to Delta. METHODS: Allocation to treatment was subject to mAbs availability, and the measured factors were not used to determine which combination to use. Patients were followed through day 30. Viral load was measured by cycle threshold (CT) on D1 (baseline) and D7. Primary outcome was time to COVID-19-related hospitalization or death from any cause over days 0-30. Weighted pooled logistic regression and marginal structural Cox model by inverse probability weights were used to compare BAM/ETE vs. CAS/IMD. ANCOVA was used to compare mean D7 CT values by intervention. Models were adjusted for calendar month, MASS score and VoCs. We evaluated effect measure modification by VoCs, vaccination, D1 CT levels and enrolment period. RESULTS: COVID19-related hospitalization or death from any cause occurred in 15 of 237 patients in the BAM/ETE group (6.3%) and in 4 of 196 patients in the CAS/IMD group (2.0%) (relative risk reduction [1 minus the relative risk] 72%; p=0.024). Subset analysis carried no evidence that the effect of the intervention was different across stratification factors. There was no evidence in viral load reduction from baseline through day 7 across the two groups (+0.17, 95% -1.41;+1.74, p=0.83). Among patients who experienced primary outcome, none showed a negative RT-PCR test in nasopharyngeal swab (p=0.009) and 82.4% showed still high viral load (p<0.001) on D7. CONCLUSIONS: In a pre-Omicron epidemiologic scenario, CAS/IMD reduced risk of clinical progression of COVID-19 compared to BAM/ETE. This effect was not associated with a concomitant difference in virological response

No Efficacy of the Combination of Lopinavir/Ritonavir Plus Hydroxychloroquine Versus Standard of Care in Patients Hospitalized With COVID-19: A Non-Randomized Comparison

Objectives: No specific treatment has been approved for COVID-19. Lopinavir/ritonavir (LPV/r) and hydroxychloroquine (HCQ) have been used with poor results, and a trial showed advantages of combined antiviral therapy vs. single antivirals. The aim of the study was to assess the effectiveness of the combination of antivirals (LPV/r and HCQ) or their single use in COVID-19 hospitalized patients vs. standard of care (SoC). Methods: Patients ≥18 years with SARS-CoV-2 infection, defined as positive RT-PCR from nasal/oropharyngeal (NP/OP) swab or positive serology, admitted at L. Spallanzani Institute (Italy) were included. Primary endpoint: time to invasive ventilation/death. Secondary endpoint: time to two consecutive negative SARS-CoV-2 PCRs in NP/OP swabs. In order to control for measured confounders, a marginal Cox regression model with inverse probability weights was used. Results: A total of 590 patients were included in the analysis: 36.3% female, 64 years (IQR 51-76), and 91% with pneumonia. Cumulative probability of invasive ventilation/death at 14 days was 21.2% (95% CI 17.6, 24.7), without difference between SOC, LPV/r, hydroxychloroquine, HCQ + LPV/r, and SoC. The risk of invasive ventilation/death in the groups appeared to vary by baseline ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2). Overall cumulative probability of confirmed negative nasopharyngeal swabs at 14 days was 44.4% (95% CI 38.9, 49.9), without difference between groups. Conclusion: In this retrospective analysis, we found no difference in the rate of invasive ventilation/death or viral shedding by different strategies, as in randomized trials performed to date. Moreover, even the combination HCQ + LPV/r did not show advantages vs. SoC
