Electromagnetic Imaging (EMI) systems use a large number of co-resident antennas usually connected to a Vector Network Analyzer via a switch. A numerical model is used to model the physical electromagnetic problem and an inversion algorithm is used to invert the collected data to produce an image of the target. However, before the computer model can be used, the raw VNA measurements must be calibrated to bridge the computational model and the true system physics. Traditional calibration approaches usually require two data sets: a data set measured from a known target for calibration purposes and a data set measured for the unknown target. In this paper, we introduce a new calibration method to calibrate and image using a single S-parameter measurement of the unknown target only. We apply this method to EMI inside of grain bins. This proposed calibration workflow: (1) estimates the bulk contents of the grain bin using a parametric inversion and (2) uses the bulk results to subsequently estimate per-channel calibration coefficients for both the transmit and receive paths to each antenna. The novel calibration procedure is demonstrated via both synthetic and experimental results, showing that single-data set calibration can provide similar quality results as traditional two-data set calibration.

Three-dimensional electromagnetic imaging can be used to monitor grain within metallic grain bins. Data acquisition requires multiple antennas surrounding the imaging space, which are used to transmit and receive the electromagnetic energy inside the bin. Due to their presence inside a metallic enclosure and due to very large mechanical forces these antennas are required to be low profile. In addition, since they are part of the imaging domain, they should be simple to model in the imaging software (i.e., using a point source). Existing half-loop magnetic field antennas meet these design criteria, but can be improved, particularly with better radiation efficiency. Herein, we present an enhanced antenna design: a ferrite-loaded shielded half-loop antenna designed to measure only the tangential component of the magnetic field against the metal enclosure wall, while rejecting the normal component of the electric field. Experimental results in two bins show that the enhanced design improves the signal level over existing probes by 6–18 dB inside a small-scale enclosure and around 20 dB inside a larger 28 m 3 (800 bushel) bin. Full 3D imaging results of a high-moisture target within a low-moisture grain background inside the test enclosure show that the enhanced antennas improve the quality of the reconstructed results in the smaller bin, particularly where the antenna performance improvements are prominent.

OBJECTIVES To assess efficacy of a gel compound containing guar, glycerine, triclosan and ethanol (Pawcare®, JOKER Technologies, Kerzers, Switzerland) in decreasing bacterial and yeast loads on the paws of dogs with erythematous, greasy and/or malodorous pododermatitis. METHODS In 20 dogs, each with at least two affected paws, semiquantitative Malassezia species counts were performed on 10 oil-immersion fields (range: 0 to 30) from acetate tapes pressed on the palmar/plantar surface of one paw. Half of the area was sampled before and the other half immediately after the application of Pawcare®. With a similar procedure, swab samples were collected from the other paw for bacterial culture, identification and evaluation of colony-forming units before and immediately after treatment. Statistical evaluation of pre- and posttreatment counts was performed with the Wilcoxon signed-rank test. RESULTS Nine dogs were positive for Malassezia species Mean acetate tape preparation counts decreased significantly from 8·78 (±8·03) to 5·668 (±6·65) (P=0·0039) after treatment. Twenty-five bacterial isolates of 11 different species were cultured in 19 dogs. Posttreatment cultures were sterile in 8 dogs that had an initial zero or low number (1 to 2 log counts) of colony-forming units. In cases with a higher pre-treatment number of colony forming units (2 to 6 log counts), there was a significant decrease - by a mean of 1·16 log counts (pre 3·12 ±1·69, post 1·96 ±1·57) (P=0·0002). CLINICAL SIGNIFICANCE The findings of the present study support the use of PawCare ® gel to decrease bacterial and yeast loads in dogs affected by chronic diseases involving the inter-digital spaces.

Background The Immuknow assay (IKA; Cylex) is a T-cell immune function assay that evaluates immunoreactivity in immunocompromised patients. The aim of this study was to analyze IKA values in a cohort of kidney transplantation (KT) recipients to investigate correlations between single–time point low IKA values and their trend over time with cytomegalovirus (CMV) or BK virus (BKV) reactivation. Methods A total of 118 adult patients receiving deceased-donor KT were enrolled (55.6 ± 11.9 years old; 79 [66.9%] male). IKA CMV and BKV viremia determinations and were performed at months 1, 3, and 6 after surgery. Results Overall, 272 IKA determinations were performed: IKA values significantly decreased from month 1 (422 ± 184 ng/mL) to month 3 (330 ± 159 ng/mL; P < .001) and from month 3 to month 6 (300 ± 128 ng/mL; P = .030). IKA values did not correlate with renal function or viral reactivation at any time. However, patients with either CMV or BKV viremia had a trend to higher IKA values at month 1 and lower IKA values at month 6, even if the difference did not reach a statistical significance ( P = .115). Conclusions Our study suggests that presence of low immunologic reactivity (IKA <225 ng/mL) is not associated with an increased risk of CMV and BKV reactivation over the 1st 6 months after KT. However, a trend to a more pronounced drop in IKA values over time was observed in patients with viral reactivation. These preliminary results suggests that drop in IKA values within the 1st post-KT months, unlike single–time point immune function assay, may predict the risk of opportunistic viral infections.

The article presents a study which investigates the association of anti-IFI16 antibodies and diseases characteristics in systemic lupus erythematosus. It states that the anti-IFI16 antibodies in the sera of 168 SLE patients were measured using an enzyme-linked-immunosorbent assay (ELISA). The result of the study shows that the renal inflammation in SLE was not contributed by anti-IFI16 antibodies.

The alteration of progenitor/stem cells present in the airway epithelium has been observed in patients with COPD. Smoking exposure induces remodeling patterns in bronchial progenitor cells (BPCs), encompassing squamous metaplasia, hyperplasia of basal and of mucus-secreting cells, and the depletion of ciliated and non-mucous secretory cells. Our aim was to assess the expression of p63 and vimentin as potential markers of airway remodeling and the regulation of stem cell populations in obstructive and neoplastic lung disease patients. A retrospective single-center observational study was conducted, including patients undergoing bronchoscopy with bronchial biopsies for suspected lung cancer. p63 and vimentin expression were evaluated via immunohistochemical analysis. There were 25 patients, of which 21 with COPD were included, and 17 were diagnosed with lung cancer. We observed that FEV1% was negatively correlated with p63+ basal cell number (r = -0.614, p = 0.019) and positively correlated with vimentin expression (r = 0.670; p = 0.008). p63 was significantly higher in biopsies from the trachea and main bronchi compared to more distal areas ( p = 0.040), whereas vimentin was prevalent in the more distal areas ( p = 0.042). Our preliminary data suggest the initial evidence of structural changes in BPCs among patients with COPD and lung cancer. Further research efforts are warranted to investigate additional morphologic and functional respiratory parameters in these patients.

Ulcerative colitis (UC) is characterized by immune system dysregulation with frequent extraintestinal manifestations, including airway involvement. A reduction in CO diffusing capacity and functional alterations in small airways have been described. An extended analysis of fractional exhaled nitric oxide (FeNO) may distinguish the sites of production, and the presence of small airway inflammation may be a useful, non-invasive marker for patient follow-up. The aim of our study was to compare the PFTs as well as FeNO and CANO values of UC patients with different clinical disease activities and healthy subjects to reveal lung function abnormalities and the presence of subclinical airway inflammation. We enrolled 42 adult outpatients at different clinical activity stages of UC (39 ± 13 years) and a healthy control group of 41 subjects (29 ± 3 years). C-reactive protein (CRP) and FeNO values at different flows (50,100, and 200 mL/s) were collected. All patients performed pulmonary function tests (PFTs) with static volumes and diffusing capacity (DLCO). FeNO and CANO values were significantly increased in UC patients when compared with controls ( p = 0.0008 and p < 0.0001, respectively) and were proportional to disease activity (FeNO class 3: 28.1 ppb vs. classes 1-2: 7.7 ppb; CANO values class 3: 8.6 ppb vs. classes 1-2: 2.7 ppb ( p < 0.0001)). TLC and DLCO were significantly reduced in severe (Mayo 3) UC patients ( p = 0.010 and p = 0.003, respectively). The results of this study show significant lung functional abnormalities in UC patients and suggest the presence of airway inflammation directly correlated with disease activity, suggesting the need for an integrated approach in routine assessment.

Introduction: Exposure to asbestos increases the risk of lung cancer and mesothelioma. Few studies quantified the premature occurrence of these diseases in asbestos-exposed workers. Focus on premature disease onset (rate advancement or acceleration) can be useful in risk communication and for the evaluation of exposure impact. We estimated rate advancement for total mortality, lung cancer and pleural mesothelioma deaths, by classes of cumulative asbestos exposure in a pooled cohort of asbestos cement (AC) workers in Italy., Method: The cohort study included 12 578 workers from 21 cohorts, with 6626 deaths in total, 858 deaths from lung cancer and 394 from pleural malignant neoplasm (MN). Rate advancement was estimated by fitting a competitive mortality Weibull model to the hazard of death over time since first exposure (TSFE)., Result: Acceleration time (AT) was estimated at different TSFE values. The highest level of cumulative exposure compared with the lowest, for pleural MN AT was 16.9 (95% CI 14.9 to 19.2) and 33.8 (95% CI 29.8 to 38.4) years at TSFE of 20 and 40 years, respectively. For lung cancer, it was 13.3 (95% CI 12.0 to 14.7) and 26.6 (95% CI 23.9 to 29.4) years, respectively. As for total mortality, AT was 3.35 (95% CI 2.98 to 3.71) years at 20 years TSFE, and 6.70 (95% CI 5.95 to 7.41) at 40 years TSFE., Conclusion: The current study observed marked rate advancement after asbestos exposure for lung cancer and pleural mesothelioma, as well as for total mortality., Competing Interests: Competing interests: The authors declare that they have no competing interests.

Objective: To find a definition of chronic disease based on literature review and to estimate the population-based prevalence rate of chronicity in a province in Northern Italy., Design: Retrospective observational study based on administrative databases., Data Sources/setting: Archives of the National Health Service that contain demographic and administrative information linked with the archives of ticket exemptions (2000-2019), the hospital discharge and drug prescriptions (2016-2019)., Participants: Subjects who lived in Vercelli Local Health Authority, a Northern Italian province (Piedmont region), and were alive in December 2019., Main Outcome Measures: Prevalence of subjects with at least one chronic disease identified by administrative sources and stratification of population according to the number of comorbidities. The pathologies considered were: chronic ischaemic heart disease, congestive heart failure, cardiac arrhythmias, hypertension, stroke, neoplasm, asthma, chronic obstructive pulmonary disease, diabetes, thyroid disorders, osteoporosis, rheumatoid arthritis, chronic kidney disease, dementia, autism spectrum disorder, depression, schizophrenia, hepatitis, HIV and substance use disorders., Results: Our target population was about 164 344 subjects. The overall prevalence of subjects with at least one chronic condition was 21.43% (n=35 212): 19 541 were female and 15 671 were male with a raw prevalence of 22.96% and 19.77%, respectively. The overall prevalence increases with age until 85 years old, then a decrease is observed. Moreover, 16.39% had only one pathology, 4.30% two diseases and 0.74% had a more complex clinical condition (more than three diseases)., Conclusions: Despite the difficulty of having a unique definition of chronic disease, the prevalence obtained was coherent with the estimates reported by other national surveillance systems such as Passi and Passi d'Argento. Underestimates were observed when international comparisons were done; however, when we used less stringent definitions of chronic diseases, similar results were obtained., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

The objective of our study was to determine the joint protective effect of a previous SARS-CoV-2 infection and vaccination on the risk of a new infection and hospitalization. Two case-control studies nested in a cohort of COVID-19 patients cared for by the Local Health Unit (LHU) of Vercelli, Italy, were performed, one to estimate the risk of infection and the second to estimate the risk of hospitalization. Each new infection and hospitalization was matched with up to 4 disease-free subjects who were the same age, sex and index date (i.e., controls). Study subjects were followed up from cohort entry date to disease outcome, end of follow-up or emigration. Vaccination was associated with a 36% (OR 0.64; 95%CI 0.62-0.66) and 90% (OR 0.10; 95%CI 0.07-0.14) reduction in the risk of infection and hospitalization, respectively. Prior infection was associated with a 65% (OR 0.35; 95%CI 0.30-0.40) and 90% (OR 0.10; 95%CI 0.07-0.14) reduction in the risk of infection and hospitalization, respectively. Vaccinated and recovered subjects showed a 63% (OR 0.37; 95%CI 0.34-0.14) and 98% (OR 0.02; 95%CI 0-0.13) reduction in the risk of infection and hospitalization, respectively. Vaccination remains an essential public health tool for preventing severe forms of COVID-19. Our study shows that vaccination or previous infection has a strong protective effect against Sars-CoV-2 hospitalization. The protective role against infection appears to be present although with a lower efficacy rate than that presented in the RCTs., (© 2023. The Author(s).)

Purpose: A multifold association relates the hypothalamo-pituitary-thyroid axis to body weight. The potential underlying mechanisms are incompletely understood. Further, the mild severity of obesity and the small proportion of individuals with obesity in so far published cohort studies provide little insights on metabolic correlates of thyroid function in obesity., Methods: We retrospectively enrolled 5009 adults with obesity (F/M, 3448/1561; age range, 18-87 years; BMI range, 30.0-82.7 kg/m 2 ), without known thyroid disease in a study on TSH and fT4 levels, lipid profile, glucose homeostasis and insulin resistance, anthropometric parameters including BIA-derived fat mass (%FM) and fat-free mass (FFM)., Results: The overall reference interval for TSH in our obese cohort was 0.58-5.07 mIU/L. As subgroups, females and non-smokers showed higher TSH levels as compared to their counterparts (p<0.0001 for both), while fT4 values were comparable between groups. There was a significant upward trend for TSH levels across incremental BMI classes in females, while the opposite trend was seen for fT4 levels in males (p<0.0001 for both). Expectedly, TSH was associated with %FM and FFM (p<0,0001 for both). TSH and fT4 showed correlations with several metabolic variables, and both declined with aging (TSH, p<0.0001; fT4, p<0.01). In a subgroup undergoing leptin measurement, leptin levels were positively associated with TSH levels (p<0.01). At the multivariable regression analysis, in the group as a whole, smoking habit emerged as the main independent predictor of TSH (β=-0.24, p<0.0001) and fT4 (β=-0.25, p<0.0001) levels. In non-smokers, %FM (β=0.08, p<0.0001) and age (β=-0.05, p<0.001) were the main significant predictors of TSH levels. In the subset of nonsmokers having leptin measured, leptin emerged as the strongest predictor of TSH levels (β=0.17, p<0.01)., Conclusions: Our study provides evidence of a gender- and smoking-dependent regulation of TSH levels in obesity., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Mele, Mai, Cena, Pagano, Scacchi, Biondi, Aimaretti and Marzullo.)

Objective: The coronavirus disease 2019 outbreak exposed intensive care unit health care workers to a psychological burden. The aim of the study was to assess burnout, depression, anxiety, and post-traumatic stress symptoms in the intensive care unit staff during the pandemic period and to focus on the factors that contributed to psychological discomfort by using validated psychometric tools., Methods: This was a monocentric study developed at the end of the first emergency crisis period (May 2020). We used a custom-designed survey using SurveyMonkey. The first part of the online survey included 27 general questions (sociodemographic information, the professional role, and possible changes assigned in job tasks and duties), the second part included validated psychometric tools: Maslach Burnout Inventory, General Health Questionnaire-12 Items, Impact of Event Scale, Beck Anxiety Inventory, and Beck Depression Inventory-II. Factors indepen- dently associated with reported symptoms of mental health disorders were identified., Results: The response rate was 88%, with 95 respondents. Depressive and mild-moderate anxiety symptoms were reported in 20% and in 12% of health care workers, respectively, and half of the sample experienced moderate or severe post-traumatic stress symptoms. In total, 64% of health care workers reported high levels of burnout. General mental health problems were more frequently reported by women (P =.3), by those who were tested negative for the coronavirus disease 2019 buffer (P < .02), and by those who changed their family habits (P =.02) as a consequence of the pandemic. Being single or divorced (P = .04) was associated with the presence of depressive symptoms; vice versa, cohabiting with a partner or being married was associated with lower levels of depression. Anxious symptoms were reported in health care workers with no previous working experience in the intensive care unit., Conclusions: Health care workers experience high levels of psychological burden during the coronavirus disease 2019 pandemic. Knowing the risk factors can aid to develop strategies of observation and prevention and also strengthen the ability to be resilient to stressful situations.

Background: Estimating the risk of intubation and mortality among COVID-19 patients can help clinicians triage these patients and allocate resources more efficiently. Thus, here we sought to identify the risk factors associated with intubation and intra-hospital mortality in a cohort of COVID-19 patients hospitalized due to hypoxemic acute respiratory failure (ARF)., Results: We included retrospectively a total of 187 patients admitted to the subintensive and intensive care units of the University Hospital "Maggiore della Carità" of Novara between March 1st and April 30th, 2020. Based on these patients' demographic characteristics, early clinical and laboratory variables, and quantitative chest computerized tomography (CT) findings, we developed two random forest (RF) models able to predict intubation and intra-hospital mortality. Variables independently associated with intubation were C-reactive protein (p < 0.001), lactate dehydrogenase level (p = 0.018) and white blood cell count (p = 0.026), while variables independently associated with mortality were age (p < 0.001), other cardiovascular diseases (p = 0.029), C-reactive protein (p = 0.002), lactate dehydrogenase level (p = 0.018), and invasive mechanical ventilation (p = 0.001). On quantitative chest CT analysis, ground glass opacity, consolidation, and fibrosis resulted significantly associated with patient intubation and mortality. The major predictors for both models were the ratio between partial pressure of arterial oxygen and fraction of inspired oxygen, age, lactate dehydrogenase, C-reactive protein, glycemia, CT quantitative parameters, lymphocyte count, and symptom onset., Conclusions: Altogether, our findings confirm previously reported demographic, clinical, hemato-chemical, and radiologic predictors of adverse outcome among COVID-19-associated hypoxemic ARF patients. The two newly developed RF models herein described show an overall good level of accuracy in predicting intra-hospital mortality and intubation in our study population. Thus, their future development and implementation may help not only identify patients at higher risk of deterioration more effectively but also rebalance the disproportion between resources and demand., (© 2021.

Background and Aim: Hematopoietic toxicities are a serious consequence of myelosuppressive CT that may result in dose reductions, delays or even discontinuation of CT, which, in turn, may compromise patient outcomes. Concerns about tolerability and costs of CSFs are still ongoing, therefore the potential use of supportive therapeutics agents are still of interest., Experimental Procedure: We performed a monocentric, phase II study using Simon's two-stage design. The primary endpoint was the evaluation of the potential clinical benefit of a special kind of honey (Life-Mel Honey) administered prophylactically to reduce the incidence of hematopoietic toxicities following chemotherapy. We have enrolled patients undergoing adjuvant or first-line chemotherapy., Results and Conclusion: From November 2013 to May 2014 (First stage) and from November 2014 to April 2016 (Second stage), 39 patients were enrolled at our Institution. The majority of patients was male (24/39, 61.5%), medium age was 60.4 years (range 34-77 years). The median follow up was 74.5 days (SD +/- 28.5). Overall, the majority of patients could underwent their chemoterapy with a regular schedule (25/39, 64.1%), while 9/39 patients (23.1%) need to delay chemotherapy due to hematological adverse events of various grade. Ten/39 patients (25.6%) had a grade 1 neutrophils count decreased, 56.4% a grade 1 platelets count decrease and 64.1% a grade 1 hemoglobin decrease. Therefore, Life-Mel Honey showed an interesting profile to reduce hematological toxicities. The proportion of responses is sufficiently high to recommend this honey to go to a next step in the clinical trial phase., Competing Interests: None., (© 2021 Center for Food and Biomolecules, National Taiwan University.

Background: Physician professionalism, including anaesthesiologists and intensive care doctors, should be continuously assessed during training and subsequent clinical practice. Multi-source feedback (MSF) is an assessment system in which healthcare professionals are assessed on several constructs (e.g., communication, professionalism, etc.) by multiple people (medical colleagues, coworkers, patients, self) in their sphere of influence. MSF has gained widespread acceptance for both formative and summative assessment of professionalism for reflecting on how to improve clinical practice., Methods: Instrument development and psychometric analysis (feasibility, reliability, construct validity via exploratory factor analysis) for MSF questionnaires in a postgraduate specialty training in Anaesthesiology and intensive care in Italy. Sixty-four residents at the Università del Piemonte Orientale (Italy) Anesthesiology Residency Program. Main outcomes assessed were: development and psychometric testing of 4 questionnaires: self, medical colleague, coworker and patient assessment., Results: Overall 605 medical colleague questionnaires (mean of 9.3 ±1.9) and 543 coworker surveys (mean 8.4 ±1.4) were collected providing high mean ratings for all items (> 4.0 /5.0). The self-assessment item mean score ranged from 3.1 to 4.3. Patient questionnaires (n = 308) were returned from 31 residents (40%; mean 9.9 ± 6.2). Three items had high percentages of "unable to assess" (> 15%) in coworker questionnaires. Factor analyses resulted in a two-factor solution: clinical management with leadership and accountability accounting for at least 75% of the total variance for the medical colleague and coworker's survey with high internal consistency reliability (Cronbach's α > 0.9). Patient's questionnaires had a low return rate, a limited exploratory analysis was performed., Conclusions: We provide a feasible and reliable Italian language MSF instrument with evidence of construct validity for the self, coworkers and medical colleague. Patient feedback was difficult to collect in our setting., Competing Interests: The authors have declared that no competing interests exist.

Background: Healthcare workers (HCWs) have been the key players in the fight against the coronavirus disease 2019 (COVID-19) pandemic. The aim of our study was to evaluate the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgG anti-bodies., Methods: We conducted a cross-sectional study among workers of two hospitals and Territorial Medical and Administrative services in Northern Italy. From 8 May to 3 June 2020, 2252 subjects were tested. Seroprevalence and 95% confidence interval (CI) were calculated for all individuals who were stratified by job title, COVID-19 risk of exposure, direct contact with patients, unit ward, and intensity of care., Results: Median age was 50 years, and 72% of subjects were female. The overall seroprevalence was 17.11% [95% CI 15.55-18.67]. Around 20% of healthcare assistants were seropositive, followed by physicians and nurses (16.89% and 15.84%, respectively). HCWs with high risk of exposure to COVID-19 were more frequently seropositive (28.52%) with respect to those with medium and low risks (16.71% and 12.76%, respectively). Moreover, personnel in direct contact had higher prevalence (18.32%) compared to those who did not (10.66%). Furthermore, the IgG were more frequently detected among personnel of one hospital (19.43%)., Conclusion: The high seroprevalence observed can be partially explained by the timing and the population seroprevalence; the study was conducted in an area with huge spread of the infection.

Aim: We aimed to characterise a large population of coronavirus disease 2019 (COVID-19) patients with moderate-to-severe hypoxaemic acute respiratory failure (ARF) receiving continuous positive airway pressure (CPAP) outside the intensive care unit (ICU), and to ascertain whether the duration of CPAP application increased the risk of mortality for patients requiring intubation., Methods: In this retrospective, multicentre cohort study, we included adult COVID-19 patients, treated with CPAP outside ICU for hypoxaemic ARF from 1 March to 15 April, 2020. We collected demographic and clinical data, including CPAP therapeutic goal, hospital length of stay and 60-day in-hospital mortality., Results: The study included 537 patients with a median (interquartile range (IQR) age of 69 (60-76) years. 391 (73%) were male. According to the pre-defined CPAP therapeutic goal, 397 (74%) patients were included in the full treatment subgroup, and 140 (26%) in the do not intubate (DNI) subgroup. Median (IQR) CPAP duration was 4 (1-8) days, while hospital length of stay was 16 (9-27) days. 60-day in-hospital mortality was 34% (95% CI 0.304-0.384%) overall, and 21% (95% CI 0.169-0.249%) and 73% (95% CI 0.648-0.787%) for full treatment and DNI subgroups, respectively. In the full treatment subgroup, in-hospital mortality was 42% (95% CI 0.345-0.488%) for 180 (45%) CPAP failures requiring intubation, and 2% (95% CI 0.008-0.035%) for the remaining 217 (55%) patients who succeeded. Delaying intubation was associated with increased mortality (hazard ratio 1.093, 95% CI 1.010-1.184)., Conclusions: We described a large population of COVID-19 patients treated with CPAP outside ICU. Intubation delay represents a risk factor for mortality. Further investigation is needed for early identification of CPAP failures., Competing Interests: Conflict of interest: R.

Objective: Italy has been a large user of asbestos and asbestos containing materials until the 1992 ban. We present a pooled cohort study on long-term mortality in exposed workers., Methods: Pool of 43 Italian asbestos cohorts (asbestos cement, rolling stock, shipbuilding, glasswork, harbors, insulation and other industries). SMRs were computed by industrial sector for the 1970-2010 period, for the major causes, using reference rates by age, sex, region and calendar period., Results: The study included 51 801 subjects (5741 women): 55.9% alive, 42.6% died (cause known for 95%) and 1.5% lost to follow-up. Asbestos exposure was estimated at the plant and period levels. Asbestos related mortality was significantly increased. All industrial sectors showed increased mortality from pleural malignancies, and most also from peritoneal and lung cancer and asbestosis, with exposure related trend. Increased mortality was also observed for ovarian cancer and for bladder cancer., Discussion: The study confirmed the increased risk for cancer of the lung, ovary, pleura and peritoneum but not of the larynx and the digestive tract. A large increase in mortality from asbestosis was observed.

Objectives: This study was performed with the aim of investigating the temporal patterns and determinants associated with mortality from asbestosis among 21 cohorts of Asbestos-Cement (AC) workers who were heavily exposed to asbestos fibres., Methods: Mortality for asbestosis was analysed for a cohort of 13 076 Italian AC workers (18.1% women). Individual cumulative asbestos exposure index was calculated by factory and period of work weighting by the different composition of asbestos used (crocidolite, amosite, and chrysotile). Two different approaches to analysis, based on Standardized Mortality Ratios (SMRs) and Age-Period-Cohort (APC) models were applied., Results: Among the considered AC facilities, asbestos exposure was extremely high until the end of the 1970s and, due to the long latency, a peak of asbestosis mortality was observed after the 1990s. Mortality for asbestosis reached extremely high SMR values [SMR: males 508, 95% confidence interval (CI): 446-563; females 1027, 95% CI: 771-1336]. SMR increased steeply with the increasing values of cumulative asbestos exposure and with Time Since the First Exposure. APC analysis reported a clear age effect with a mortality peak at 75-80 years; the mortality for asbestosis increased in the last three quintiles of the cumulative exposure; calendar period did not have a significant temporal component while the cohort effect disappeared if we included in the model the cumulative exposure to asbestos., Conclusions: Among heaviest exposed workers, mortality risk for asbestosis began to increase before 50 years of age. Mortality for asbestosis was mainly determined by cumulative exposure to asbestos., (© The Author(s) 2020.

Background and Purpose: The role of radiotherapy (RT) in the treatment of hemangiopericytoma/solitary fibrous tumor (HPC/SFT) is still under debate. We aimed at investigating whether radiotherapy can improve the results in patients operated for extracranial HPC/SFT., Materials and Methods: Data from patients with HPC/SFT, treated from 1982 to 2012, were retrospectively reviewed within the Rare Cancer Network framework. Actuarial local control (LC), disease-free survival (DFS), metastasis-free survival (MFS) and overall survival (OS) were calculated with Kaplan-Meyer method. Patient and tumor parameters were analyzed by univariate and multivariate analysis., Results: Of 114 HPC/SFT, 58 (50.9%) occurred in the extremities/superficial trunk and 56 (49.1%) in intra-thoracic/retroperitoneum. Seventy-eight patients (68.4%) underwent surgery only (Sx), and 36 (31.6%) Sx and RT (Sx + RT). Median RT dose was 60 Gy (range 45-68.4 Gy) in 1.6-2.2 Gy fractions. In the extremities/superficial trunk group of patients, actuarial 5-year LC rates were 50.4% after Sx and 91.6% after Sx + RT (p < 0.0001) for LC, and 50.4% after Sx and 83.1% after Sx + RT (p = 0.008) for DFS. In the intra-thoracic/retroperitoneum group of patients, actuarial 5-year rates were 89.3% after Sx and 77.8% after Sx + RT (p = 0.99) for LC, and 73.8% after Sx and 77.8% after Sx + RT (p = 0.93) for DFS. At multivariate analysis, the addition of RT resulted in better LC and DFS in the whole series. The advantage was confirmed for LC in the group of patients affected by extremity/superficial trunk tumors., Conclusion: Addition of RT to Sx could improve the prognosis, in terms of LC and DFS, essentially in patients with extremities/superficial trunk tumor locations., (Copyright © 2019 Elsevier B.V.

Aims: To evaluate OPN, MCM7, Ki-67, p53, Bcl-2 and 53BP1 presence, together with the abnormal adaptive CD4 and CD8 T-cell response markers expression in a series of oral lichen planus (OLP) affected patients and assess their combined contribution for a more objective disease classification., Methods and Results: In this ex-vivo retrospective analysis, biopsy specimens from 28 adults with a clinical diagnosis of OLP at different progression degree (16 reticular, 2 plaque-like, 1 erosive and 9 mixed type) were collected. Sections were immunohistochemically investigated for the proinflammatory cytokine osteopontin (OPN), alpha-beta CD4 and CD8 positive T cells, DNA replication licensing factor (MCM7), proliferating cell marker (Ki-67), apoptotic and tumor antigen (p53), apoptosis modulator (Bcl-2) and cellular response regulator to double-strand breaks tumor suppressor p53-binding protein 1 expression. Statistical analysis revealed that 53BP1 is highly represented among the OLP study patients (p<0.05). Moreover, on the basis of the quantification results of the highly expressed parameters, two illness categories with different severity were evidenced. The classification hypothesis was confirmed by i) OLP lesion persistence, ii) the development of oral severe lesions in the patients belonging to high grade activity OLP group (HGA-OLPs) and iii) the ascertainment of the same evidence both in the oral squamous cell tumor controls (OSCC) and in HGA-OLP cases., Conclusion: This study completes the scenario with respect to early detection, thanks to a more precise histological analysis, for rationalizing the clinical and histological findings toward a sharable international disease scoring system.

Objectives: Models based on the multistage theory of cancer predict that rates of malignant mesothelioma continuously increase with time since first exposure (TSFE) to asbestos, even after the end of external exposure. However, recent epidemiological studies suggest that mesothelioma rates level off many years after first exposure to asbestos. A gradual clearance of asbestos from the lungs has been suggested as a possible explanation for this phenomenon. We analysed long-term trends of pleural and peritoneal cancer mortality in subjects exposed to asbestos to evaluate whether such trends were consistent with the clearance hypothesis., Methods: We used data from a pool of 43 Italian asbestos cohorts (51 801 subjects). The role of asbestos clearance was explored using the traditional mesothelioma multistage model, generalised to include a term representing elimination of fibres over time., Results: Rates of pleural cancer increased until 40 years of TSFE, but remained stable thereafter. On the other hand, we observed a monotonic increase of peritoneal cancer with TSFE. The model taking into account asbestos clearance fitted the data better than the traditional one for pleural (p=0.004) but not for peritoneal (p=0.09) cancer., Conclusions: Rates of pleural cancer do not increase indefinitely after the exposure to asbestos, but eventually reach a plateau. This trend is well described by a model accounting for a gradual elimination of the asbestos fibres. These results are relevant for the prediction of future rates of mesothelioma and in asbestos litigations., Competing Interests: Competing interests: SM served as expert witness for the judge, the public prosecutor and the defendant’s attorneys in court trials regarding asbestos-related diseases.

Background: Despite the available information on cancer risk, asbestos is used in large areas in the world, mostly in the production of asbestos cement. Moreover, questions are raised regarding the shape of the dose response relation, the relation with time since exposure and the association with neoplasms in various organs. We conducted a study on the relationship between cumulative asbestos exposure and mortality from asbestos related diseases in a large Italian pool of 21 cohorts of asbestos-cement workers with protracted exposure to both chrysotile and amphibole asbestos., Methods: The cohort included 13,076 workers, 81.9% men and 18.1% women, working in 21 Italian asbestos-cement factories, with over 40 years of observation. Exposure was estimated by plant and period, and weighted for the type of asbestos used. Data were analysed with consideration of cause of death, cumulative exposure and time since first exposure (TSFE), and by gender. SMRs were computed using reference rates by region, gender and calendar time. Poisson regression models including cubic splines were used to analyse the effect of cumulative exposure to asbestos and TSFE on mortality for asbestos-related diseases. 95% Confidence Intervals (CI) were computed according to the Poisson distribution., Results: Mortality was significantly increased for 'All Causes' and 'All Malignant Neoplasm (MN)', in both genders. Considering asbestos related diseases (ARDs), statistically significant excesses were observed for MN of peritoneum (SMR: men 14.19; women 15.14), pleura (SMR: 22.35 and 48.10), lung (SMR: 1.67 and 1.67), ovary (in the highest exposure class SMR 2.45), and asbestosis (SMR: 507 and 1023). Mortality for ARDs, in particular pleural and peritoneal malignancies, lung cancer, ovarian cancer and asbestosis increased monotonically with cumulative exposure. Pleural MN mortality increased progressively in the first 40 years of TSFE, then reached a plateau, while peritoneal MN showed a continuous increase. The trend of lung cancer SMRs also showed a flattening after 40 years of TSFE. Attributable proportions for pleural, peritoneal, and lung MN were respectively 96, 93 and 40%., Conclusions: Mortality for ARDs was associated with cumulative exposure to asbestos. Risk of death from pleural MN did not increase indefinitely with TSFE but eventually reached a plateau, consistently with reports from other recent studies.

Aims and Objectives: To explore the effect of "Primary Nursing" on nursing-sensitive patient outcomes, staff-related outcomes and organisation-related outcomes., Background: Primary nursing is one example of a care pattern that has recently been implemented in many countries., Design: Before-after study., Methods: This study was conducted in an Italian hospital. We observed patient-related outcomes (pressure ulcers, falls, urinary tract infection and venous catheter infection) in 2,857 inpatients before the implementation of primary nursing and in 3,169 inpatients after its implementation. Staff-related outcomes (nursing competence and diagnostic thinking) and organisation-related outcomes (empowerment and team climate) were collected from 369 nurses. From a subgroup of inpatients, we collected data regarding their satisfaction with the care provided., Results: After the implementation of primary nursing, some nursing competencies and diagnostic thinking were improved, so were organisation-related outcomes. Our data showed that the number of inpatients with urinary catheter infections (5.5% vs. 4.3%) and venous catheter infections (peripheral: 2.2% vs. 1%; central: 5.6% vs. 1%) was significantly decreased; also, the numbers of falls (2.4% vs. 1.9%) and pressure ulcers (4.8% vs. 4%) decreased, although these decreases were not statistically significant. Overall, the implementation of primary nursing increased patient satisfaction with nursing care (193.57 vs. 210.21)., Conclusions: Primary nursing improved staff-related outcomes, nursing-sensitive patient outcomes and organisation outcomes., Relevance to Clinical Practice: Our results show that primary nursing has the potential to positively impact on inpatients, nurses and organisations. Moreover, the implementation of this care pattern is feasible., (© 2017 John Wiley & Sons Ltd.)

Objective: Asbestos is a known human carcinogen, with evidence for malignant mesothelioma (MM), cancers of lung, ovary, larynx and possibly other organs. MM rates are predicted to increase with a power of time since first exposure (TSFE), but the possible long-term attenuation of the trend is debated. The asbestos ban enforced in Italy in 1992 gives an opportunity to measure long-term cancer risk in formerly exposed workers., Methods: Pool of 43 previously studied Italian asbestos cohorts (asbestos cement, rolling stock, shipbuilding), with mortality follow-up updated to 2010. SMRs were computed for the 1970â€"2010 period, for the major causes, with consideration of duration and TSFE, using reference rates by age, sex, region and calendar period., Results: The study included 51 801 subjects (5741 women): 55.9% alive, 42.6% died (cause known for 95%) and 1.5% lost to follow-up. Mortality was significantly increased for all deaths (SMR: men: 1.05, 95% CI 1.03 to 1.06; women: 1.17, 95% CI to 1.12 to 1.22), all malignancies combined (SMR: men: 1.17, 95% CI to 1.14 to 1.20; women: 1.33, 95% CI 1.24 to 1.43), pleural and peritoneal malignancies (SMR: men: 13.28 and 4.77, 95% CI 12.24 to 14.37 and 4.00 to 5.64; women: 28.44 and 6.75, 95% CI 23.83 to 33.69 and 4.70 to 9.39), lung (SMR: men: 1.26, 95% CI 1.21 to 1.31; women: 1.43, 95% CI 1.13 to 1.78) and ovarian cancer (SMR=1.38, 95% CI 1.00 to 1.87) and asbestosis (SMR: men: 300.7, 95% CI 270.7 to 333.2; women: 389.6, 95% CI 290.1 to 512.3). Pleural cancer rate increased during the first 40 years of TSFE and reached a plateau after., Discussion: The study confirmed the increased risk for cancer of the lung, ovary, pleura and peritoneum but not of the larynx and the digestive tract. Pleural cancer mortality reached a plateau at long TSFE, coherently with recent reports., Competing Interests: Competing interests: The following authors reported that they served as expert witness for the public prosecutor in court trials on asbestos related diseases: CM, EM, DM, EO, SS., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Background: Treatment of canine otitis externa with owner-administered products can be difficult., Objectives: To evaluate otic treatment administered by a veterinarian on quality of life (QoL) of dogs with otitis externa and their owners, and on clinical and cytology parameters of otitis; compared to an owner-administered treatment., Animals: Fifty client-owned dogs randomly randomized into two groups and treated for 2 weeks., Methods: Veterinarians treated Group A dogs with a veterinary licensed otic gel on two occasions at a 1 week interval; owners treated Group B dogs once daily with a veterinary licensed otic drop based product along with twice weekly cleaning. Veterinarians evaluated otitis with the OTI-3 scale and semi-quantitative cytological examination on days 0, 7, 14 and 28. At each visit, owners assessed QoL with a validated questionnaire and pruritus with a Visual Analog Scale. Scores before and after treatment of each group, and differences between groups were analysed statistically., Results: In both groups, all parameters improved significantly. There was a significantly higher improvement of QoL scores, for dogs and owners, in Group A, compared to Group B at all time points (P < 0.05), except for owner QoL on Day 28. There was no difference in improvement of OTI-3 between groups at any time point, whereas Group A cytology scores and pruritus improved significantly more by Day 7 (P = 0.0026 and P = 0.0294, respectively)., Conclusion: A veterinarian-administered otic gel provided equivalent efficacy and higher QoL to dogs with otitis externa and their owners, compared to an owner-administered topical otic therapy., (© 2017 The Authors.
