Abstract
BACKGROUND There is no consensus on the second-line treatment of patients with progressive high-grade neuroendocrine neoplasms (NENs G3) and large-cell lung neuroendocrine carcinoma. These patients generally have poor performance status and low tolerance to combination therapy. In this trial, we aim to evaluate the efficacy and safety of temozolomide given every other week in patients with advanced platinum-pretreated NENs G3. PATIENTS AND METHODS This trial is an open-label, non-randomized, phase II trial. Patients with platinum-pretreated metastatic neuroendocrine carcinoma were treated with 75 mg/m2/day of temozolomide for 7 days, followed by 7 days of no treatment (regimen one week on/one week off). The primary endpoint was the overall response rate. Secondary endpoints included progression-free survival (PFS), overall survival (OS), safety and tolerability. This study is registered with ClinicalTrials.gov, NCT04122911. RESULTS From 2017 to 2020, 38 patients were enrolled. Among the patients with determined Ki67, 12 out of 36 (33.3%) had a Ki67 index <55% and the remaining 24 out of 36 (66.6%) had an index ≥55%. Overall response rate was 18% (7/38), including one complete response and six partial responses. The median PFS was 5.86 months [95% confidence interval (CI) 4.8 months-not applicable) and the median OS was 12.1 months (95% CI 5.6-20.4 months). The 1-year PFS rate was 37%. No statistically significant difference in median PFS [hazard ratio 1.3 (95% CI 0.6-2.8); P = 0.44] and median OS [hazard ratio 1.1 (95% CI 0.5-2.4); P = 0.77] was observed among patients with Ki67 <55% versus ≥55%. Only G1-G2 adverse events were registered, the most common being G1 nausea, diarrhea and abdominal pain. CONCLUSION One week on/one week off temozolomide shows promising activity in patients with poorly differentiated NEN. The good safety profile confirmed the possibility of using this scheme in patients with poor performance status.

Abstract
Toll-like receptors (TLRs) in mammalian systems are well known for their role in innate immunity. In addition, TLRs also fulfil crucial functions outside immunity, including the dorsoventral patterning function of the original Toll receptor in Drosophila and neurogenesis in mice. Recent discoveries in flies suggested key roles for TLRs in epithelial cells in patterning of junctional cytoskeletal activity. Here, we address the function of TLRs and the downstream key signal transduction component IRAK4 in human epithelial cells. Using differentiated human Caco-2 cells as a model for the intestinal epithelium, we show that these cells exhibit baseline TLR signalling, as revealed by p-IRAK4, and that blocking IRAK4 function leads to a loss of epithelial tightness involving key changes at tight and adherens junctions, such as a loss of epithelial tension and changes in junctional actomyosin. Changes upon IRAK-4 inhibition are conserved in human bronchial epithelial cells. Knockdown of IRAK4 and certain TLRs phenocopies the inhibitor treatment. These data suggest a model whereby TLR receptors near epithelial junctions might be involved in a continuous sensing of the epithelial state to promote epithelial tightness and integrity.

Abstract
The maintenance of the functional integrity of the intestinal epithelium requires a tight coordination between cell production, migration, and shedding along the crypt-villus axis. Dysregulation of these processes may result in loss of the intestinal barrier and disease. With the aim of generating a more complete and integrated understanding of how the epithelium maintains homeostasis and recovers after injury, we have built a multi-scale agent-based model (ABM) of the mouse intestinal epithelium. We demonstrate that stable, self-organizing behaviour in the crypt emerges from the dynamic interaction of multiple signalling pathways, such as Wnt, Notch, BMP, ZNRF3/RNF43, and YAP-Hippo pathways, which regulate proliferation and differentiation, respond to environmental mechanical cues, form feedback mechanisms, and modulate the dynamics of the cell cycle protein network. The model recapitulates the crypt phenotype reported after persistent stem cell ablation and after the inhibition of the CDK1 cycle protein. Moreover, we simulated 5-fluorouracil (5-FU)-induced toxicity at multiple scales starting from DNA and RNA damage, which disrupts the cell cycle, cell signalling, proliferation, differentiation, and migration and leads to loss of barrier integrity. During recovery, our in silico crypt regenerates its structure in a self-organizing, dynamic fashion driven by dedifferentiation and enhanced by negative feedback loops. Thus, the model enables the simulation of xenobiotic-, in particular chemotherapy-, induced mechanisms of intestinal toxicity and epithelial recovery. Overall, we present a systems model able to simulate the disruption of molecular events and its impact across multiple levels of epithelial organization and demonstrate its application to epithelial research and drug development.

Abstract
BACKGROUND Cognitive impairment of intellectual developmental disorders (IDD) is determined by several different combinations of specific cognitive alterations. People with IDD present a rate of mental health problems that is up to 4 times higher than that of the general population. Despite this, the relationship between specific cognitive dysfunctions and co-occurring mental disorders has not been adequately studied. The aim of the present paper is to investigate the association between specific cognitive dysfunctions and specific psychiatric symptoms and syndromes in people with IDD. METHODS One hundred and twenty adults with mild to moderate IDD living in residential facilities underwent a clinical and instrumental assessment for specific cognitive and psychopathological features. RESULTS Participants with IDD and ASD have significantly lower scores compared to those without respect to who has not the diagnosis on the Processing Speed Index (PSI) and Perceptual Reasoning Index (PRI) on the WAIS-IV and higher time scores on the TMT A. Moreover, there is a significant association between years of hospitalisation and TMT B and TMT B A time scores; the longer a participant with IDD was hospitalised, the worse their performance on the TMT. Although not statistically significant, many psychopathological clusters showed substantial cognitive profiles. CONCLUSIONS Although further research is needed, neuropsychological and IQ tests scores seem to be differently associated to various psychopathological conditions co-occurring with IDD, and with ASD especially. Cognitive assessment seems to support diagnosis and treatment of psychopathological co-occurrences in persons with IDD, also in consideration of indirect implications including a better knowledge of the patient's characteristics beyond IQ deficit.

Abstract
Abstract
Background
Secondary prevention measures have strongly contributed to the reduction of incidence and mortality of cervical cancer (CC) identifying women at high risk of developing it. This cross-sectional study aimed to investigate the acceptability of a home-based self-sampling methodology for Human Papilloma Virus (HPV) testing and the factors that may influence women’s preference.
Methods
A random sample of women over the age of 50 years has been selected in Southern part of Italy. Data was collected through an anonymous self-administered questionnaire and included socio-demographic characteristics, knowledge of HPV infection and prevention measures, and attitudes towards the acceptability of self-collected cervico-vaginal sampling (CVS) and urine sampling (US).
Results
Among the 321 women who completed the survey, more than two-thirds (73.7%) knew that CC is caused by HPV, only 68.9% knew that the HPV screening is useful for an early detection and diagnosis of CC, and 17% never had Pap-test or HPV-DNA test. Of the respondents, 67.9% declared that they preferred self-collected US for future HPV testing compared with clinician-taken cervical samples (CCS). The most common reasons reported for preferring US included that it was easier (54.8%), more convenient (28.7%), and less embarrassing (21.7%). Among those women who showed negative attitude towards self-collected US, 8 out of 10 (77.3%) expressed scepticism about its diagnostic performance. Only 37% of the sample preferred CVS, and this attitude is mainly attributable to the fear of not carrying out a correct self-sampling (71.2%) and to its underrated diagnostic performance (33.7%).
Conclusions
The preliminary results suggest that US is more acceptable than CCS and CVS in Italy. Urinary HPV test presents similar accuracy of the latter tests to detect CC and its supply in the context of population-based screening programmes could improve adherence, reducing the cost and burden on physicians.
Key messages
• Urine self-sampling could represent an innovative early detection approach to increase adherence to cervical cancer screening programmes.
• Further research is needed to assess whether the screening status and the strategy of self-samplers distribution could act as predictors of screening uptake.

Abstract
Abstract
Background
More than 600 million people around the world get sick every year due to eating contaminated food, which is impressive considering that all foodborne diseases (FDs) are preventable. Contamination during food preparation by food handlers (FHs) is one of the main causes of FDs. The aim of this study is to assess the knowledge and behaviors of FHs related to FDs.
Methods
The cross-sectional study was conducted in two regions (i.e. Calabria and Sicily) of Southern Italy. Data was collected through an anonymous self-administered questionnaire designed to retrieve sociodemographic information, knowledge about food safety, and food-handling behaviors among a randomly selected sample of FHs ≥ 18 years of age.
Results
Findings refer to a sample of 171 respondents with a mean age of 40 years (SD ± 12.7). A vast majority (63.7%) of FHs did not know the correct procedure for hand washing according to Food & Drug Administration (FDA) guidelines and 28.4% of subjects did not wash their hands after touching raw food, which constitutes a major risk of food cross-contamination. One-third of FHs were unknowledgeable that cross-contamination (e.g. using the same utensils for cooked and raw foods) could lead to FDs. Multiple logistic regression analysis showed a positive correlation (p < 0.001) among good knowledge and proper food-handling practices, such as using separate kitchen utensils to prepare cooked and raw foods and storing them in separate areas or fridges. Less than half of the sample (42.1%) reported the need for more information about FDs.
Conclusions
Preliminary results highlight a lack of knowledge about simple rules to avoid food cross-contamination that could negatively impact on food safety and food-handling behaviors. This study add evidence about areas where intervention are needed to reduce the occurrence of FDs.

Abstract
Abstract
Background
Flu vaccination during pregnancy has been proven to be effective in preventing illness and hospitalization in both pregnant women and newborns. However, flu vaccination uptake is still suboptimal. The study aimed to assess if healthcare providers (HCPs) are knowledgeable about flu vaccination recommendation during pregnancy and if they routinely recommend the vaccination.
Methods
The present survey was carried out among obstetricians-gynaecologists (OBs), midwives and primary care physicians (PCPs) in the Southern part of Italy. Data were collected through an anonymous self-administered questionnaire that included professional information, knowledge, perceptions and practices on flu vaccination during pregnancy.
Results
96 participants were hitherto enrolled (36.5% OBs, 35.4% PCPs and 28.1% midwives). Among the responders, 63.5% and 66.7% knew that flu vaccination can be administrated during any trimester of pregnancy and reduces the risk of preterm birth and miscarriage, respectively. Alarmingly, more than a fifth (22.9%) of the sample believed that vaccines during pregnancy are more dangerous than safe and only 67.7% routinely recommend the flu vaccine to all women regardless of their stage in pregnancy. Among HCPs who did not recommend the flu shot, the most frequently reported reasons were that flu vaccine recommendation was outside the scope of their practice (62.5%), that women are more hesitant about vaccines during pregnancy (37.5%) and lack of time (25%).
Conclusions
The preliminary results highlight alarming gaps in knowledge (e.g. immunization timing) and suboptimal routine recommendation of the flu vaccine that represents a missed opportunity. Indeed, it has been demonstrated that when women are offered vaccination, most tend to accept it.
Key messages
• Unmotivated concerns about vaccine safety during pregnancy have to be addressed among HCPs to enhance flu recommendation and, subsequently, immunization coverage in pregnant women.
• Strategies to disseminate evidence-based recommendations to HCPs regarding flu immunization during pregnancy have to be implemented and evaluated in order to improve public health.

Abstract
Abstract
Background
Immunization programs are key preventive interventions and have largely contributed to reducing the burden of infectious diseases and decreasing related morbidity, mortality and healthcare costs. The study aimed to investigate coverage regarding diphtheria, tetanus, and acellular pertussis (dTap) - Inactivated Poliomyelitis Vaccine (IPV) and Human Papilloma Virus (HPV) vaccine and attitudes towards vaccinations among undergraduate university students in Southern Italy.
Methods
This cross-sectional study was conducted among 327 students through an anonymous online questionnaire and included socio-demographic characteristics, attitudes towards vaccinations overall and specifically on dTap-IPV and HPV, reasons for having received or not vaccinations and willingness to receive vaccinations.
Results
One third of the students were concerned about serious adverse effects of vaccines and 95% believed that vaccines for uncommon diseases are useless. During adolescence, 89% of the sample received the mandatory dTap-IPV vaccine booster. Among unvaccinated students, 45% were unwilling to get vaccinated against dTap-IPV because they believed not to be at risk of infection (59%) and had lack of recommendation (35.3%). Regarding vaccination against HPV, 67% had received the recommended schedule. Among those who did not receive it, 34% were unwilling to get vaccinated because they did not feel at risk of HPV infection (41%). Interestingly, 16% of the sample disclosed some barriers to access vaccination centers. Moreover, 30% declared that HPV vaccination was discouraged by healthcare professionals (HCPs).
Conclusions
Vaccination uptake is worryingly low and national objective coverage seems not still achieved. Likewise, risk perception of vaccine-preventable diseases was low and it seems negatively impact on the intention to get vaccinated. Improving vaccine confidence among HCPs is crucial as they have been shown to have the potential to influence patient vaccination uptake.

Abstract
Abstract
Background
Diphtheria, tetanus and pertussis (dTap) vaccination is heavily endorsed during pregnancy. However, maternal dTap immunization rates in Italy remain low. Lack of healthcare workers (HCWs) recommendation to get vaccinated represents one of the main barriers to immunization during pregnancy. Therefore, this study aimed to investigate what HCWs know about dTap vaccination, practices and potential barrier to recommending immunization during pregnancy.
Methods
This cross-sectional study was conducted among obstetricians-gynaecologists (OBs), midwives and general practitioners (GPs) in 2 regions of Southern Italy. An anonymous self-administered questionnaire was used to collect data on professional information, knowledge, risk perceptions and practices regarding dTap vaccination during pregnancy.
Results
Until now 94 HCWs were recruited (36.2% OBs, 35.1% GPs and 28.7% midwives). Overall, 63.8% knew that dTap vaccination has to be administered during the third trimester of gestation and 94.7% that it is able to protect newborns against pertussis before active immunization. One-third of the HCWs believed that vaccines in pregnancy were more dangerous than safe. Seven out of ten HCWs routinely recommended dTap vaccine and provided information about dTap vaccination to all pregnant women. Most frequent reported reasons for not recommending dTap vaccination during pregnancy were that it was outside the scope of their practice (72.4%), that women are more vaccine hesitant during pregnancy (42.9%), lack of time (28.6%), lack of knowledge on the topic (28.6%) and the belief that the vaccine could interfere with the development of the fetus (14,3%).
Conclusions
Lack of knowledge, unsatisfactory recommendation of dTap immunization during pregnancy and uncertainty over their responsibility around vaccination suggest that public health organisations should strengthen dissemination and implementation of evidence-based recommendations.
Key messages
• Barriers to recommending dTap immunization during pregnancy remain among healthcare workers.
• Strategies (e.g. electronic reminders) to facilitate HCWs in recommending and informing on dTap immunization should be implemented and evaluated to improve vaccination coverage in pregnant women.

Abstract
OBJECTIVE To determine whether women who experience resolution of low placentation (low-lying placenta or placenta previa) are at increased risk of postpartum hemorrhage compared to those with normal placentation throughout pregnancy. METHODS This was a retrospective cohort study of women who delivered at Mount Sinai Hospital between 2015 and 2019, and who were diagnosed with low-lying placenta or placenta previa on transvaginal ultrasound at the time of the second-trimester anatomical survey, with resolution of low placentation on subsequent ultrasound examination. Women undergoing second-trimester anatomical survey who had normal placentation on transvaginal ultrasound 3 days before or after the cases were randomly identified for comparison. The primary outcome was the rate of postpartum hemorrhage. Secondary outcomes included the need for a blood transfusion, use of additional uterotonic medication, the need for additional procedures to control bleeding, and maternal admission to the intensive care unit. Outcomes were assessed using a multivariable logistic regression model. RESULTS A total of 1256 women were identified for analysis, of whom 628 had resolved low placentation and 628 had normal placentation. Women with resolved low placentation, compared to those with normal placentation throughout pregnancy, had significantly higher mean age (33.0 ± 5.4 years vs 31.9 ± 5.5 years; P < 0.01) and lower mean body mass index at delivery (27.9 ± 5.5 kg/m2 vs 30.2 ± 5.7 kg/m2 ; P < 0.01), and were more likely to have undergone in-vitro fertilization, be of non-Hispanic white race, have posterior placental location (all P < 0.01) and have private/commercial health insurance (P = 0.04). Patients with resolved low placentation vs normal placentation had greater odds of postpartum hemorrhage (adjusted odds ratio (aOR), 3.5 (95% CI, 2.0-6.0); P < 0.01), use of additional uterotonic medication (aOR, 2.2 (95% CI, 1.5-3.1); P < 0.01) and increased rates of additional procedures to control bleeding (aOR, 4.0 (95% CI, 1.3-11.9); P = 0.01). CONCLUSION Despite high rates of resolution of low-lying placenta and placenta previa by term, women with resolved low placentation remain at increased risk of postpartum hemorrhage compared to those with normal placentation throughout pregnancy. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
BACKGROUND The choice of inhaler device for asthma patients depends upon multiple attributes. We investigated factors that may drive general practitioners (GPs) and respiratory specialists in the prescription of inhaler devices for asthma patients who initiated inhalation therapy. METHODS We retrospectively analysed prescriptions by GPs and respiratory specialists to asthma patients commencing inhaled corticosteroid/long-acting β2-agonist combination therapy available as both pressurised metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs). Patient characteristics were compared by device and multivariate analysis was used to model the likelihood of receiving a pMDI as opposed to a DPI in order to identify drivers for prescription. A sample of the respiratory specialists completed an ad-hoc survey of their perceived success in achieving asthma control in their patients and barriers to attaining full control. RESULTS Prescription of a particular inhaler device was unrelated to the characteristics of the patients. Multivariate analysis revealed that the main driver for the choice of inhaler device was the medication (Odds Ratio and 95% Confidence Interval, respectively for GPs and specialists: 0.19 [0.16-0.23]; 0.17 [0.08-0.37]). Specialists perceived asthma as being inadequately controlled in 41% of their patients, and considered patients' difficulties in using DPIs and pMDIs as instrumental in this, citing a need for a novel, more effective inhaler technology. CONCLUSION Physicians choose inhaler devices according to the prescribed drugs and not to the characteristics of the individual patient. This may reflect a lack of confidence in existing inhaler devices and underlines the need for technologies, which are more reliable and easier to use by patients.

Abstract
Computer generated holograms (CGHs) are powerful optical elements used in many fields, such as wavefront shaping, quality testing of complex optics, and anti-counterfeiting devices. The Lee algorithm is the most used to generate binary amplitude Fourier holograms. Grayscale CGHs are known to give a higher reconstruction quality than binary holograms, but they usually require a cumbersome production process. A very simple and straightforward method of manufacturing rewritable grayscale CGHs is proposed here by taking advantage of two key components: a digital micro-mirror device (DMDs) and a photochromic plate. An innovative algorithm, named Island algorithm, able to generate grayscale amplitude Fourier CGHs, is reported and compared with the standard Lee approach, based on 9 levels. A crucial advantage lies on the fact that the increase or decrease of the quantification does not affect the spatial resolution. In other words, the new coding leads to a higher spatial resolution (for a given CGH size) and a reconstructed image with an order of magnitude higher contrast with respect to the classical Lee-coded hologram. In order to show the huge potential of our approach, a 201 level Island hologram is designed, produced and reconstructed, pushing the contrast to values higher than104. These results reveal the potential of our process as well as our algorithm for generating programmable grayscale CGHs.

Abstract
Influenza D virus (IDV) is a new viral genus identified within the Orthomyxoviridae family, showing 50 per cent amino acid identity with human influenza C virus. Similar to human influenza viruses of the C genus, IDV also harbors 7 genomic segments and uses 9-O-acetylated sialic acids as cell receptors. This newly emerged virus exhibits a broad host range and is capable of infecting swine, cattle, sheep, goats, ferrets, and guinea pigs. In Italy, IDV was first detected in archived samples collected between 2014 and 2015 from cattle and swine in the Po Valley area. Here, we report the genetic characterization of IDV viruses detected in an extensive area of northern Italy, namely Veneto, Lombardy, and Piedmont, through passive surveillance between September 2015 and October 2017. A total of 482 samples, including nasal swabs, lungs, and bronchoalveolar lavage fluid, collected from 309 cattle farms were tested. Thirty cattle herds turned out to be positive, for a total of 40 samples positive by Real Time RT-PCR targeting the PB2 gene. Representative IDV positive swabs were sequenced on an Illumina Miseq platform, and phylogenetic analyses were performed for each genome segment. The analyses of the seven gene segments demonstrated that the viruses identified in the north of Italy clearly grouped within a genetic cluster of IDV sequences previously described in Italy and in the USA, thus suggesting a common origin for these viruses. Interestingly, the IDVs identified in Italy presented a low similarity (96.1% to 98.8% for the seven gene segments) to the French IDVs, which is the only other European country where this pathogen has been identified and characterized so far. The wide IDV host range and the ability of this virus to reassort are a matter of concern. Results of this study indicate that IDV is extensively circulating among bovine herds in Northern Italy and suggest a potential role of IDV in the bovine respiratory disease complex, highlighting the need to perform surveillance on an ongoing basis to track its spread and evolution.

Abstract
Abstract
Osimertinib is a next-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) with activity against both the activating and the ‘gatekeeper’ T790M EGFR mutations. An acquired EGFR C797S mutation has been reported to mediate osimertinib resistance in approximately 15% and 7% of patients in second-line and first-line treatment respectively. This percentage in the first-line setting will likely evolve as the first line data mature. The C797S mutation leads to the loss of covalent binding of osimertinib to mutant EGFR. The high affinity of the EGFR triple mutant for ATP presents a challenge for reversible inhibitor design, particularly as the loss of the cysteine at position 797 precludes the previously exploited covalent approaches. We have explored various approaches to address this challenge, including an effort to maximise reversible affinity to target the C797S mutation without requiring a covalent bond. We describe herein the therapeutic potential of reversible phosphine oxide pyrazole inhibitors in tumors harboring C797S.
Using structure-based design, we were able to design a series of phosphine oxide pyrazole inhibitors that displayed exceptionally high biochemical potency against EGFR C797S mutation, which translated into good activity in cell-based assays. Using CRISPR-Cas 9 genome editing technology, we engineered cellular disease-relevant models to express the C797S mutation to evaluate potency in vitro and in vivo.
By modulating the physicochemical properties of our in vitro leads, we were able to achieve good oral exposure of cellularly active EGFR C797S inhibitors such as AZ’7608. We showed that AZ’7608 inhibits signalling pathways and cellular growth of C797S EGFR cell lines in vitro and demonstrated an improved WT EGFR margin. This translated into 52% (p<0.05, at day 14) tumor growth inhibition in vivo when compared to the control group. The efficacy of AZ’7608 is enhanced by its combination with anti-EGFR antibody, showing tumor regression (82%, p<0.001). In addition, we performed pharmacodynamic studies to explore the relationship between efficacy and target/pathway modulation. These studies establish a clear relationship between depth and duration of inhibition of the phosphorylation of EGFR and anti-tumor efficacy.
The work presented herein shows a proof of concept for reversible phosphine oxide pyrazole inhibitors to target tumors harboring C797S. The emergence of the C797S EGFR mutation remains a key area of unmet need and warrants further efforts in drug discovery.

Abstract
Adiponectin (Acrp30) plays an important role in energy metabolism and inflammation. Recently, in vivo serum Acrp30 levels have been reported to be correlated to risk of developing several types of cancers such as lung cancer, and in vitro studies have demonstrated a role for Acrp30 in the control of cell proliferation and survival. However, the molecular effects of Acrp30 on lung cancer have not yet been clearly defined. In the present study, we investigated the effects of different concentrations of Acrp30 on the A549 human alveolar epithelial cell line, an in vitro model of lung adenocarcinoma. A549 cells were exposed to various concentrations of Acrp30 and successively, proliferation, apoptosis and oxidative stress were evaluated by MTT test, caspase activity assay, flow-cytometry and western blotting analysis. Our results demonstrated that Acrp30 causes, in a time- and dose-dependent manner, a reduction of cell viability and duplication together with an increase in cell apoptosis rate. In addition, we found that Acrp30 induces an increase of lipid peroxidation evaluated by TBARS assay and a concomitant reduction of nitric oxide release, both markers of cellular oxidative stress. Taken together, our data on A549 cells provides new insight into potential involvement of Acrp30 on physio-pathologic mechanisms of lung diseases through interference with proliferation, apoptosis and oxidative status.

Abstract
Strength, power and muscular endurance tests have been developed as means of assessing people's physical abilities. However, testing may be expensive or time consuming. A method to reduce the time of physical assessment could be to use predictive algorithms for indirect assessment. The aim of this study will be to determine a relationship between strength, power and muscular endurance in order to identify predictors for an easier and faster assessment. 33 male strength-trained participants (22.8 ± 4.6 years, 172.5 ± 6.7 cm, 68.0 ± 10.6 kg) performed a single pull-up (SPU) and a single push-up (SPH) and a set of pull-ups (EPU) and push-ups (EPH) to exhaustion. The participants were divided into three sub-groups according to their training experience. Force(F), Power(P), Velocity(V) and relative power(R-P), extracted from an accelerometer (500 Hz), were compared between groups (ANOVA) and a subsequent linear regression analysis was performed to identify predictors of the performance measures. The regression models were able to explain 61% of the variance with the EPU as dependent variable and the V of the SPU as independent variable and 68% of the variance with the EPH as dependent variable and EPU as independent variable. In addition, increased performance measures were found according to training experience, in particular regarding muscular endurance of both the EPU and EPH (p < 0.001 and p < 0.01, respectively). A significant effect of training experience was also present for the V of the SPU (p < 0.001). The results indicate that a relation between muscular endurance and velocity is present. The generated equations allow to estimate both the number of EPH and EPU from a SPU. The equations may be helpful to reduce the time of assessment for upper body physical evaluation.

Abstract
Aims and Background Patients treated for Hodgkin's disease with chemotherapy or with the association of chemotherapy and radiotherapy have an increased risk of secondary leukemia. The aim of this study was to evaluate the leukemogenic risk due to these treatment modalities. Methods We performed a case-control study on a population of 1410 patients treated for Hodgkin's disease from 1970 to 1990 in our Institute. Among these patients, we identified 25 cases of secondary leukemia and 3 cases of myelodysplasia, all occurring more than one year after the diagnosis of Hodgkin's disease. Three cases occurred among the patients treated with radiotherapy alone. When we analyzed the risk in relation to the type of treatment (radiotherapy, chemotherapy, or both), the comparisons were relative to patients treated with radiotherapy alone. Results We found that chemotherapy alone is associated with a fivefold increased risk (odds ratio = 5.4) compared with radiotherapy alone. When both treatments are used, the risk is not further increased (odds ratio = 4.4). Patients receiving more than 6 courses of chemotherapy have an excess risk (relative risk = 2.5) compared with those treated with 6 courses or less. No increased risk was observed after splenectomy. Conclusions This study confirms an increased incidence of secondary leukemia occurring in patients treated for Hodgkin's disease. The increased risk seems to be correlated with the number of courses of alkylating agent therapy, whereas it is unaffected by the addition of radiotherapy.

Abstract
PURPOSE The incidence of neuroendocrine tumors (NETs) is progressively increasing. Most cases arise from the digestive system, where ileum, rectum and pancreas represent the commonest site of origin. Liver metastases are frequently detected at diagnosis or during the follow-up. Contrast-enhanced ultrasound (CEUS) is used in patients with pancreatic NETs (P-NETs) and liver metastases from P-NET but its role has not been standardized. The aim of this retrospective study was to investigate CEUS in patients with P-NETs and liver metastases from P-NET both as prognostic factor and predictor of response to therapy with somatostatin analogues (SSAs). METHODS CEUS was performed at the diagnosis of NET and 3, 6 and 12 months after the beginning of SSAs. CEUS pattern was compared with contrast-enhanced computed tomography (CT) pattern. RESULTS There was a significant association between CEUS and CT pattern (X 2 = 79.0; p < 0.0001). A significant association was found between CEUS pattern and Ki-67 index (X 2 = 24.6; p < 0.0001). The hypervascular homogeneous CEUS typical pattern was associated with low tumor grading (G1 or G2) (X 2 = 24.0; p < 0.0001). CEUS pattern changed from hypervascular homogeneous in baseline to hypovascular/hypervascular inhomogeneous after SSA therapy, with a significant association between tumor response at CT scan and appearance of hypervascular inhomogeneous pattern at CEUS evaluation (6 months: X 2 = 57.0; p < 0.0001; 12 months: X 2 = 49.8; p < 0.0001). CONCLUSIONS In patients with P-NET, CEUS pattern correlates with tumor grading, being homogeneous in G1-G2 but not in G3 tumors. After therapy with SSAs, CEUS is predictive of response to SSAs. These findings seem to support a role of CEUS as prognostic and predictive factor of response.

Abstract
Cell-specific proteomics in multicellular systems and whole animals is a promising approach to understand the differentiated functions of cells and tissues. Here, we extend our stochastic orthogonal recoding of translation (SORT) approach for the co-translational tagging of proteomes with a cyclopropene-containing amino acid in response to diverse codons in genetically targeted cells, and create a tetrazine-biotin probe containing a cleavable linker that offers a way to enrich and identify tagged proteins. We demonstrate that SORT with enrichment, SORT-E, efficiently recovers and enriches SORT tagged proteins and enables specific identification of enriched proteins via mass spectrometry, including low-abundance proteins. We show that tagging at distinct codons enriches overlapping, but distinct sets of proteins, suggesting that tagging at more than one codon enhances proteome coverage. Using SORT-E, we accomplish cell-specific proteomics in the fly. These results suggest that SORT-E will enable the definition of cell-specific proteomes in animals during development, disease progression, and learning and memory. A tetrazine-biotin probe containing a cleavable linker was created Proteomes labeled with cyclopropene amino acids were enriched and identified Proteome coverage is increased by targeting the amino acids to multiple codons Cell-specific proteomics was accomplished in the fly

Abstract
Abstract
EGFR exon 20 insertion (Ex20Ins) mutations represent a combination of in-frame insertions and/or duplications that account for 4-10% of all EGFR mutants in non-small cell lung cancer (NSCLC). To date, more than one hundred different Ex20Ins mutations have been identified. With the notable exception of the rare A763_Y764insFQEA insertion (<1%), EGFR Ex20Ins mutations are clinically unresponsive to early generation EGFR inhibitors, the standard of care for NSCLC patients with EGFR Ex20Ins mutations is chemotherapy. Therefore, a significant unmet need remains requiring the development of an EGFR TKI agent that can more effectively target NSCLC with EGFR Ex20Ins mutations. Osimertinib is a newly developed EGFR TKI approved for the treatment of advanced NSCLC with EGFR T790M tumors. This work describes the potential of osimertinib and AZ5104, a circulating metabolite of osimertinib, in Ex20Ins tumours.
Using CRISPR-Cas 9 genome editing technology, we engineered cellular disease relevant models carrying the most prevalent Ex20Ins mutations, namely Ex20Ins D770_N771InsSVD (22%) or Ex20Ins V769_D770InsASV (17%).
Using these models, we show that osimertinib and AZ5104 inhibit signalling pathways and cellular growth of Ex20Ins CRISPR-Cas9 engineered cell lines in vitro. This translates into sustained tumor growth inhibition in vivo in both the Ex20Ins SVD (65%, p<0.001 & 95%, p<0.001 respectively at day 14) and Ex20Ins ASV (82%, p<0.001 & 95%, p<0.001 respectively at day 14) xenograft models when compared to the control group. Importantly in vivo osimertinib was dosed at exposures consistent with the 80 mg osimertinib clinical dose. Moreover, a dual EGFR blockade strategy combining osimertinib or AZ5104 with cetuximab (an EGFR antibody) improved the anti tumor effect further. We also describe the anti-tumor activity of osimertinib and AZ5104 using a series of patient derived xenograft models harbouring the rarer Ex20Ins H773-V774insNPH and M766-A767insASV mutations. In addition, we performed pharmacodynamic studies to explore the relationship between efficacy and target/pathway modulation. These studies establish a clear relationship between depth and duration of phospho-EGFR inhibition and anti tumor efficacy. Interestingly, we observed that downstream signalling molecules displayed a more transient inhibition than the phospho
EGFR signal. Two patients from the AURA Phase 2 osimertinib trials with plasma positive Ex20Ins (concurrent with Ex19del and T790M) had durable PFS responses of 6.4 and 13.9 months, supporting the premise that osimertinib has the potential to be clinically beneficial in tumors harboring Ex20Ins.
The work presented herein demonstrates that osimertinib has the potential to improve upon the current treatment options for NSCLC patients whose tumors harbour an Ex20Ins mutation, and warrants its further clinical investigation.

Abstract
In this study, the activation of H2O2 and persulfate ions induced by solar photolysis of Fe(III)EDDS complex were investigated in water disinfection, applying solar AOPs processes. The use of Fe(III)EDDS complex maintains iron in soluble form until slightly basic pH and so the photolysis is efficient in a large range of pH compatible with natural waters. Moreover, for the first time, the impact of photogenerated hydroxyl and sulfate radicals on the inactivation of Enterococcus faecalis in water was studied. E. faecalis was proposed as alternative model microorganism given its higher resistance than the commonly used E. coli. The reactivity of hydroxyl radicals seems to be more efficient for the inactivation of such strain than the reactivity of sulfate radicals. Moreover, experimental results show that the concentration of Fe(III)EDDS complex is a key parameter for the inactivation of microrganisms. For the direct application in natural waters, the efficiency of the process in the presence of ubiquitous inorganic compounds, such as carbonate (HCO3-/CO32-) and chloride ions (Cl-), was also investigated. Carbonates showed a strong reduction on the E. faecalis inactivation in all cases; meanwhile chloride ions enhanced the inactivation in the presence of persulfate as also shown by using a complementary kinetic modeling approach. A dual role of Fe(III)EDDS complex was established and discussed; essential for the generation of radical species but a trap for the reactivity of these same radicals.

Abstract
IntroductionRecently, new patient-oriented outcome measures have emerged in mental health research and practice. Among these, generic quality of life (GQoL) has gained a central place and has come to represent a valid endpoint in most settings, from basic care programs to clinical trials, especially for the field of intellectual disability (ID). However, most studies still refer to health-related QoL, and the tools for the assessment of GQoL present many issues related to the structure complexity and administration time.AimThe purposes is to evaluate psychometric properties of a new rapid tool for the GQoL assessment named QuIQ (quick instrument for quality of life), originally constructed for use for people with ID.MethodsTwo hundred and ten persons with ID were consecutively administered with the QuIQ. A part of them were also assessed with the BASIQ, the Italian adaptation of the quality of life instrument package. QuIQ has the same conceptual framework and refers to the same areas of the BASIQ, but include a low number of dimensions (only attribution of importance and perception of satisfaction) and a factor way of score attribution such as visual analogue scale and graphic geometrical mean calculation.ResultsQuIQ showed good internal coherence (Cronbach's α = 0.92), inter-rater reliability (Cohen's K > 0.93), and concurrent validity (> 0.8) with BASIQ.ConclusionThese findings seem to display for the QuIQ good psychometric characteristics. They also suggest that it could be possible to apply rapid QoL assessment to all the range of people with ID. This could have very important implications for future massive use in different settings.

Abstract
Computer Generated Holograms (CGHs) are used for wavefront shaping and complex optics testing. Present technology allows for recording binary CGHs. We propose a Digital Micro-mirror Device (DMD) as a reconfigurable mask, to record rewritable binary and grayscale CGHs on a photochromic plate. Opaque at rest, this plate becomes transparent when it is illuminated with visible light of suitable wavelength. We have successfully recorded the very first amplitude grayscale CGH, with a contrast greater than 50, which was reconstructed with a high fidelity in shape, intensity, size and location. These results reveal the high potential of this method for generating programmable/rewritable grayscale CGHs, which combine DMDs and photochromic substrates.

Abstract
Abstract
Background: Previous reports from the Anastrozole Tamoxifen Alone or in Combination (ATAC) trial have shown significantly prolonged disease-free survival, lower rates of recurrence and distant recurrence, and reduced contralateral breast cancer in patients treated with anastrozole compared to tamoxifen (Cuzick et al., Lancet, 2010). Here, we compare the long-term effects of anastrozole versus tamoxifen in patients randomised to either monotherapy arm in the ATAC trial.
Methods: Postmenopausal women with hormone receptor positive breast cancer randomised to anastrozole or tamoxifen in the main ATAC trial were eligible for the LATTE observational study. The primary objective was to compare the long-term effects of tamoxifen and anastrozole on time to recurrence and death beyond 10 years after randomisation. Secondary objectives included time to distant recurrence, cancer-specific survival, new breast primaries, other cancers, fractures, and cardiac/cerebrovascular events. Cox proportional hazard methods were used to compute hazard ratios (95% CI) for recurrence from the time of last publication (10 years median follow-up).
Results: 2452 women from 11 countries were entered into the LATTE study. 40 women withdrew consent and 759 women died or had a recurrence within 10 years, which left 1653 women for analysis (838 anastrozole vs. 815 tamoxifen). A total of 118 breast events (69 anastrozole (8.2%) vs. 49 tamoxifen (6.0%)) were reported. No significant difference between the two treatment arms were observed (HR=1.36 (0.94-1.97), P=0.098). 57 women had a distant recurrence (33 (3.9%) vs. 24 (2.9%)), 41 reported a loco-regional recurrence (23 (2.7%) vs. 18 (2.2%)), and 26 contra-lateral breast cancer were recorded (17 (2.0%) vs. 9 (1.1%)). None of the treatment comparisons were statistically significant. 305 deaths were recorded (147 (17.5%) vs. 158 (19.4%)), of which 31 were due to breast cancer. Significantly fewer gynaecological cancers were recorded with anastrozole (7 vs. 16; OR=0.42 (0.15-1.09), P=0.05), but overall the effect on other cancers was not significant (54 (6.4%) vs. 64 (7.9%). Fractures, cardiovascular, and cerebrovascular events were evenly distributed between the treatment arms.
Conclusions: Although anastrozole was associated with significant fewer recurrences compared to tamoxifen in the first 10 years of follow-up, in this analysis, with limited number of patients, we could not find a significant difference between the two treatment arms.

Abstract
Spinal trauma is a devastating event with a high morbidity and mortality. The rationale of imaging is to diagnose the traumatic abnormalities and characterize the type of injury, to estimate the severity of the lesions, to evaluate the potential spinal instability. In case of spinal instability, the goals of operative treatment are decompression of the spinal cord canal and stabilization of the disrupted vertebral column. Particularly, diagnostic imaging, mainly by CT and MR, has a main role in the post-treatment evaluation. The neuroradiological evaluation of the postoperative spine requires a general knowledge of the surgical approach to each spinal region and of the normal temporal evolution of expected postoperative changes. The neuroradiologist should evaluate the devices implanted, their related complications and promptly alert the surgeon of acute complications, mainly vascular and infective. During the follow-up, it is mandatory to know and search chronic complications as pseudomeningocele, accelerated degenerative disease, arachnoiditis, peridural fibrosis. Knowledge of specific complications relating to each surgical approach will assist the neuroradiologist in interpretation of postoperative images.

Abstract
Two nuclear genes, ACTN3, encoding for the α-actinin skeletal muscle isoform 3, and ACE encoding the angiotensin-converting enzyme, have both been associated with quantitative physical performance traits in the general population. The purpose of our study was to assess the association between the two nuclear gene variants, R577X (rs1815739) in ACTN3 and I/D (rs4340) in ACE, with elite athletes performance and the effect of training on the mitochondrial DNA (mtDNA) content in peripheral blood. We evaluated the genotypes and frequencies of ACTN3 R577X and ACE I/D polymorphisms between soccer players (n = 43) and healthy non-athletic controls (n = 128). Total DNA was extracted from peripheral blood samples using the standard procedure. The genotypes were assessed by PCR-RFLP analysis and mtDNA cellular content by RT-PCR. The soccer players showed a tendency to a prevalence of ACTN3RR and ACEDD genotypes both independently and in co-occurrence. The effect of physical training on the mitochondrial DNA content in the athletic population was reflected strikingly in its increase in peripheral blood. Based on our results, we suggest that the analysis of ACTN3 and ACE genotypes could predict talent in the soccer field and that knowledge of the genetic variants could determine types and training times for soccer players. In addition, the novelty of this work, never before described in the sports literature, is that the increase of mitochondrial content can be correlated with the training load, suggesting that the mtDNA copy number may be considered a viable bioenergetics biomarker.

Abstract
A re-examination of Scrophularia canina L. confirmed the presence of iridoid glucosides considered as chemotaxonomic markers for the Scrophulariaceae family, like aucubin, harpagide and 8-O-acetylharpagide, besides the further presence of 8-epiloganic acid, which is, indeed, considered the biogenetic precursor of iridoids normally found in Scrophulariaceae, and was recognised here for the first time in the studied species. Also verbascoside and (E)-phytol were evidenced for the first time in S. canina. The former compound is an almost ubiquitous glycosidic phenyl-ethanoid, which attains systematic importance when in co-occurrence with iridoids, and its taxonomical implications were discussed. The latter compound, even though it is omnipresent, is interestingly endowed with several biological activities, which may give an additional reason for the traditional uses of this plant.
