Further Clarification of Pain Management Complexity in Radiotherapy: Insights from Modern Statistical Approaches. Cancers (Basel) 2024; 16:1407. [PMID: 38611085 PMCID: PMC11010980 DOI: 10.3390/cancers16071407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 03/18/2024] [Accepted: 03/29/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND The primary objective of this study was to assess the adequacy of analgesic care in radiotherapy (RT) patients, with a secondary objective to identify predictive variables associated with pain management adequacy using a modern statistical approach, integrating the Least Absolute Shrinkage and Selection Operator (LASSO) algorithm and the Classification and Regression Tree (CART) analysis. METHODS This observational, multicenter cohort study involved 1387 patients reporting pain or taking analgesic drugs from 13 RT departments in Italy. The Pain Management Index (PMI) served as the measure for pain control adequacy, with a PMI score < 0 indicating suboptimal management. Patient demographics, clinical status, and treatment-related factors were examined to discern the predictors of pain management adequacy. RESULTS Among the analyzed cohort, 46.1% reported inadequately managed pain. Non-cancer pain origin, breast cancer diagnosis, higher ECOG Performance Status scores, younger patient age, early assessment phase, and curative treatment intent emerged as significant determinants of negative PMI from the LASSO analysis. Notably, pain management was observed to improve as RT progressed, with a greater discrepancy between cancer (33.2% with PMI < 0) and non-cancer pain (73.1% with PMI < 0). Breast cancer patients under 70 years of age with non-cancer pain had the highest rate of negative PMI at 86.5%, highlighting a potential deficiency in managing benign pain in younger patients. CONCLUSIONS The study underscores the dynamic nature of pain management during RT, suggesting improvements over the treatment course yet revealing specific challenges in non-cancer pain management, particularly among younger breast cancer patients. The use of advanced statistical techniques for analysis stresses the importance of a multifaceted approach to pain management, one that incorporates both cancer and non-cancer pain considerations to ensure a holistic and improved quality of oncological care.

Adequacy of Pain Management in Patients Referred for Radiation Therapy: A Subanalysis of the Multicenter ARISE-1 Study. Cancers (Basel) 2023; 16:109. [PMID: 38201537 PMCID: PMC10778440 DOI: 10.3390/cancers16010109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 12/18/2023] [Accepted: 12/20/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND Pain is a prevalent symptom among cancer patients, and its management is crucial for improving their quality of life. However, pain management in cancer patients referred to radiotherapy (RT) departments is often inadequate, and limited research has been conducted on this specific population. This study aimed to assess the adequacy and effectiveness of pain management when patients are referred for RT. Moreover, we explored potential predictors of adequate pain management. METHODS This observational, prospective, multicenter cohort study included cancer patients aged 18 years or older who were referred to RT departments. A pain management assessment was conducted using the Pain Management Index (PMI), calculated by subtracting the pain score from the analgesic score (PMI < 0 indicated inadequate pain management). Univariate and multivariate analyses were performed to identify predictors of adequate pain management. RESULTS A total of 1042 cancer outpatients were included in the study. The analysis revealed that 42.9% of patients with pain did not receive adequate pain management based on PMI values. Among patients with pain or taking analgesics and referred to palliative or curative RT, 72% and 75% had inadequate or ineffective analgesic therapy, respectively. The odds of receiving adequate pain management (PMI ≥ 0) were higher in patients undergoing palliative RT (OR 2.52; p < 0.001), with worse ECOG-PS scores of 2, 3 and 4 (OR 1.63, 2.23, 5.31, respectively; p: 0.017, 0.002, 0.009, respectively) compared to a score of 1 for those with cancer-related pain (OR 0.38; p < 0.001), and treated in northern Italy compared to central and southern of Italy (OR 0.25, 0.42, respectively; p < 0.001). CONCLUSIONS In this study, a substantial proportion of cancer patients referred to RT departments did not receive adequate pain management. Educational and organizational strategies are necessary to address the inadequate pain management observed in this population. Moreover, increasing the attention paid to non-cancer pain and an earlier referral of patients for palliative RT in the course of the disease may improve pain response and treatment outcomes.

Abstract
The aim of this paper was to assess the cost-effectiveness of pembrolizumab in first-line for microsatellite-instability-high or mismatch-repair-deficient metastatic colorectal cancer. We have considered the pivotal phase III randomized controlled trial of pembrolizumab in first-line for microsatellite-instability-high mismatch-repair-deficient metastatic colorectal cancer. The last available update of each trial was considered as the original source. Incremental cost-effectiveness ratio was calculated as the ratio between the difference of the costs in the intervention and in the control groups (pharmacy costs) and the difference between the effect in the intervention and in the control groups (progression-free survival). The costs of drugs are at the Pharmacy of the Mater Salutis Hospital of Legnago (VR, Italy) and are expressed in euros (€). Three hundred and seven patients were considered in the pivotal phase III randomized controlled trial. Pembrolizumab obtained a cost per month progression-free survival gained ranged from 6471 € towards mFOLFOX (5-FU, oxaliplatin and leucovorin) plus cetuximab to 7886 € towards mFOLFOX. To sum up, combining pharmacological costs of drugs with the measure of efficacy represented by progression-free survival, at the actual prize pembrolizumab cannot be considered cost-effectiveness for first-line treatment for microsatellite-instability-high mismatch-repair-deficient metastatic colorectal cancer. A reduction in pharmacological costs is mandatory.

Abstract
BACKGROUND & AIMS Determining outcomes using the total neoadjuvant therapy (TNT) in patients with local advanced rectal cancer is important for stratifying patients according to expected outcomes in future studies in the era of treatment combination. The present meta-analysis estimated the pathological complete response, disease-free survival, and overall survival probabilities of rectal cancer patients and identified predictors of outcomes. METHODS Studies reporting pathological complete response rate and time-dependent outcomes (progression or death) after total neoadjuvant treatment of locally advanced rectal cancer (LARC) were identified in MEDLINE through January 2022. Three independent observers extracted data on patient populations and outcomes and combined the data using a distribution-free summary survival curve. The primary outcomes were actuarial probabilities of recurrence and survival. RESULTS Fourteen RCTs, including 18 TNT arms, met the inclusion criteria. The pooled estimate of pathological complete response (pCR) probability was 23.6%, with moderate heterogeneity between studies. The pooled estimates of actuarial disease-free survival rate were 70.6% at 3 years and 65.4% at 5 years. The pooled estimates of actuarial survival rates were 93% at 3 years and 81.6% at 5 years. In both these outcomes, heterogeneity between studies was highly significant. CONCLUSION This meta-analysis showed that Total Neoadjuvant Therapy is an optimal approach for LARC patients. The results provide a useful benchmark for future comparisons of the benefits of combinations of other drug families as target therapies or immunotherapies.

Adequacy of Pain Treatment in Radiotherapy Departments: Results of a Multicenter Study on 2104 Patients (Arise). Cancers (Basel) 2022; 14:cancers14194660. [PMID: 36230582 PMCID: PMC9563985 DOI: 10.3390/cancers14194660] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 09/20/2022] [Accepted: 09/22/2022] [Indexed: 11/19/2022] Open
Abstract
Aim: The frequent inadequacy of pain management in cancer patients is well known. Moreover, the quality of analgesic treatment in patients treated with radiotherapy (RT) has only been rarely assessed. In order to study the latter topic, we conducted a multicenter, observational and prospective study based on the Pain Management Index (PMI) in RT Italian departments. Methods: We collected data on age, gender, tumor site and stage, performance status, treatment aim, and pain (type: CP—cancer pain, NCP—non-cancer pain, MP—mixed pain; intensity: NRS: Numeric Rating Scale). Furthermore, we analyzed the impact on PMI on these parameters, and we defined a pain score with values from 0 (NRS: 0, no pain) to 3 (NRS: 7−10: intense pain) and an analgesic score from 0 (pain medication not taken) to 3 (strong opioids). By subtracting the pain score from the analgesic score, we obtained the PMI value, considering cases with values < 0 as inadequate analgesic prescriptions. The Ethics Committees of the participating centers approved the study (ARISE-1 study). Results: Two thousand one hundred four non-selected outpatients with cancer and aged 18 years or older were enrolled in 13 RT departments. RT had curative and palliative intent in 62.4% and 37.6% patients, respectively. Tumor stage was non-metastatic in 57.3% and metastatic in 42.7% of subjects, respectively. Pain affected 1417 patients (CP: 49.5%, NCP: 32.0%; MP: 18.5%). PMI was < 0 in 45.0% of patients with pain. At multivariable analysis, inadequate pain management was significantly correlated with curative RT aim, ECOG performance status = 1 (versus both ECOG-PS3 and ECOG- PS4), breast cancer, non-cancer pain, and Central and South Italy RT Departments (versus Northern Italy).Conclusions: Pain management was less adequate in patients with more favorable clinical condition and stage. Educational and organizational strategies are needed in RT departments to reduce the non-negligible percentage of patients with inadequate analgesic therapy.

Abstract
Active elastic instabilities are common phenomena in the natural world, where they have the character of sudden mechanical morphings. Frequently, the driving force of the instability mechanisms has a chemo-mechanical nature, which makes the instabilities very different from the standard elastic instabilities. In this paper, we describe and study the active elastic instability occurring in a swollen spherical closed shell, confining a water-filled cavity, during a dehydration process. We set up a few numerical experiments based on a stress-diffusion model to give an insight into the phenomenon. Then, we present a study that looks at the chemo-mechanical problem and, through a few simplifying assumptions, allows us to derive a semi-analytical model of the phenomenon. It takes into account both the stress state and the water concentration in the walls of the shell at the onset of the instability. Moreover, it considers the invariance of the cavity volume at the onset of instability, which is due to the impossibility of instantaneously changing the cavity volume filled with water. Eventually, it is shown that the semi-analytic model matches very well the outcomes of the numerical experiments far from the initial regime; the ranges of validity of the approximated analytical model are also discussed.

Abstract
We study a prototypical system describing instability effects due to geometric constraints in the framework of nonlinear elasticity. By considering the equilibrium configurations of an elastic ring constrained inside a rigid circle with smaller radius, we analytically determine different possible shapes, reproducing well-known physical phenomena. As we show, both single- (with different complexity) and multi-blister configurations can be observed, but the lowest energy always corresponds to single-blister solutions. Important physical insight is attained through an analogy between the elastica and the dynamics of a nonlinear pendulum. A complete geometric characterization is attained, proving symmetry and other relevant properties. The effectiveness of the model is tested against a simple experiment by considering a thin polymer strip constrained in a rigid cylinder.

Abstract
PURPOSE To evaluate tolerance and biochemical control rates of salvage external beam radiotherapy (EBRT) in patients with local relapse from prostate cancer (PC) after high-intensity focused ultrasound (HIFU) as primary treatment. METHODS Twenty-four patients presented biochemical failure of PC. Salvage EBRT to the residual prostate was performed with moderate hypofractionation schedule (MHRT) in 28 fractions (n = 16) or with extreme hypofractionation schedule (SBRT) in 5 fractions (n = 8) by means of image-guided volumetric modulation arc therapy. In case of MHRT, the median dose was 71.4 Gy, whereas in case of SBRT it was 32.5 Gy. RESULTS The median follow-up was 28 months. The median PSA nadir was 0.26 ng/mL. In case of MHRT, the median PSA nadir was 0.15 ng/mL and occurred within a median time of 19 months. In case of SBRT, the median PSA nadir was 0.64 ng/mL and occurred within a median time of 8 months. No G3 higher acute or late toxicity after EBRT was observed. Only three patients presented with G2 acute GI toxicity (actinic proctitis). Twelve patients experienced acute G1 GU toxicity: 8/16 of men treated with MHRT and 4/8 of men treated with SBRT. Complete local control of disease was achieved in 23/24 patients (96%). CONCLUSIONS Our data confirm the feasibility and the low toxicity of salvage EBRT with both schedules of treatment after HIFU failure. The findings of low acute toxicity and good biochemical control rates are encouraging, but a larger number of patients and a longer follow-up are needed to confirm these results.

Abstract
Stereotactic radiosurgery (SRS) is an effective treatment option for multiple brain metastases (BMs). Modern mono-isocentric techniques allow the delivery of multiple stereotactic courses, in the event of intracranial failure. Nevertheless, limited data on effectiveness and toxicity have been reported in comparison to WBRT. Aim of this retrospective matched-pair analysis was to compare patients affected by limited BMs treated with multiple SRS courses using a mono-isocentric, non-coplanar technique (HyperArc™, Varian Medical System) to upfront WBRT. One hundred and two patients accounting for 677 BMs were treated with HyperArc™. In case of further intracranial progression, 44 treatment courses of 201 metastases in 19 patients, were treated by subsequent HyperArc™ courses. This population was matched with 38 patients treated with WBRT. The median BMs number was 4 (range 2-10) for HyperArc™ and 5 (range 2-10) for WBRT. Overall survival (OS) and toxicity were evaluated. The median follow-up was 9 months (range 3-40 months). The median OS was not reached (range 5-22 months) for HyperArc™ patients and 8 months (range 3-40 months) for WBRT patients, while the 1-year OS was 77% and 34.6% for HyperArc™ and WBRT, respectively (p = 0.001; HR 4.77, 95% CI 1.62-14.00). There was one case of radionecrosis. HyperArc™ is an effective and safe technique for the treatment of multiple BMs. In selected cases of intracranial oligorecurrence, further subsequent courses can be safely delivered with the same technical approach. Moreover, in patients with a limited number of BMs, SRS showed an improved survival outcome when compared to WBRT.

Abstract
Objective A cross-sectional study on knowledge, perceptions, and adherence to cervical cancer screening was conducted using telephone interviews of Sicilian women that were performed in 2016. This study aimed to identify areas that need to be addressed to improve the validity of data collection and to minimize possible biases. Methods We performed a qualitative study through SWOT analysis, which is a multidimensional method based on evaluation of Strengths (S), Weaknesses (W), Opportunities (O), and Threats (T) of the research project. The contents of the SWOT forms underwent categorical, inductive, and deductive data analysis using the long table analysis method. Results The full availability of an updated address and phone number list was the main organizational aspect to be addressed. Socio-cultural context played a major role for understanding the questions and for acceptability of the topics. In some cases, a family member was a facilitating element, while in others, the family member hindered the interviews. Active involvement of general practitioners was considered essential for success of the interviews. Conclusions When performing a cross-sectional survey, organizational aspects and active involvement of general practitioners are crucial in the enrolment phase, regardless of the socio-cultural context.

Abstract
PURPOSE External beam radiotherapy (EBRT) is an effective treatment option for low- and favorable intermediate-risk prostate cancer (PCa) and it is usually delivered in conventional fractionation or with moderate hypofractionation (hRT), with comparable results. In the last years, a new treatment approach with stereotactic body radiotherapy (SBRT) has shown promising results. The aim of the present study was to directly compare the toxicity and outcome between hRT and SBRT in low and favorable intermediate PCa patients. MATERIALS AND METHODS The hRT schedules were: 71.4 Gy or 74.2 Gy in 28 fractions for low- or favorable intermediate-risk PCa, respectively, while the SBRT schedules were: 35 Gy or 37.5 Gy in five fractions, for low or favorable intermediate risk, respectively. Toxicity assessment was performed according to CTCAE v5.0 grading. The International Prostatic Symptoms Score (IPSS) was also recorded. RESULTS One hundred forty-nine patients were analyzed, overall 81 (54.36%) patients were low risk and 68 (45.64%) were favorable intermediate risk. Sixty-nine (46.3%) patients were treated with hypo-RT and 80 (53.7%) with SBRT. Median follow-up was 33 months (range 11-58 months). The actuarial survival rate was 98.66%. The 3-years BFS rates were 95.5% and 100% for hRT and SBRT, respectively (p = 0.051). One case (0.6%) of acute grade 3 urinary toxicity occurred in a patient with favorable intermediate risk treated with hRT. He initially suffered gross hematuria and acute urinary retention not treatable with urinary catheter, therefore a suprapubic catheter was placed and steroids were administered. No differences in acute, late or severe toxicity were detected. CONCLUSION Stereotactic body radiotherapy reported a good clinical outcome and safe toxicity profile. Results are comparable to hRT, but a longer follow-up is needed to assess the late effectiveness and toxicity.

Abstract
Elastic rods in contact provide a rich paradigm for understanding shape and deformation in interacting elastic bodies. Here, we consider the problem of determining the static solutions of two nested elastic rings in the plane. If the inner ring is longer than the outer ring, it will buckle creating a space between the two rings. This deformation can be further influenced by either adhesion between the rings or if pressure is applied externally or internally. We obtain an exact solution of this problem when both rings are assumed inextensible and unshearable. Through a variational formulation of the problem, we identify the boundary conditions at the contact point and use the Kirchhoff analogy to give exact solutions of the problems in terms of elliptic functions. The role of both adhesion and pressure is explored.

Abstract
Vaccine knowledge of the general population is shaped by different information sources and strongly influences vaccination attitudes and uptake. The CCM-Italian Ministry of Health ESCULAPIO project attempted to identify the role of such information sources, in order to address adequate strategies to improve information on vaccines and vaccine preventable diseases. In the present study, data on 632 adults from Southern Italy regarding information sources were collected, and their perceived and actual knowledge on vaccinations were compared and analyzed in relation to socio-demographic characteristics and information sources. The main reported reference sources were general practitioners (GPs) (42.5%) and pediatricians (33.1%), followed by mass media (24.1%) and the Internet (17.6%). A total of 45.4% reported they believed to be informed (45.4%), while those estimated to be truly informed were 43.8%. However, as showed in the multivariate logistic regression, people having the perception to be correctly informed ascribed their good knowledge to their profession in the health sector (Adj OR 2.28, CI 1.09-4.77, p < 0.05) and to friends/relatives/colleagues (AdjOR 6.25, CI 2.38-16.44, p < 0.001), while the non-informed population thought the responsibility had to be attributed to mass media (AdjOR 0.45, CI 0.22-0.92, p < 0.05). Those showing the real correct information, instead, were younger (AdjOR 1.64, CI 1.04-2.59, p < 0.05), and their main reference sources were pediatricians (AdjOR 1.63, CI 1.11-2.39, p < 0.05) and scientific magazines (Adj OR 3.39, CI 1.51-7.59, p < 0.01). Only 6% knew the "VaccinarSì" portal, developed to counter the widespred antivaccine websites in Italy. The post-survey significant increase of connections to "VaccinarSi" could be ascribed to the counselling performed during questionnaire administration. Strategies to improve information about vaccination should be addressed to fortifying healthcare workers knowledge in order to make them public health opinion leaders. General population should be provided with correct indications on trustworthy websites on vaccines to contrast false information supplied by anti-vaccinists on their own websites or social networks pages and on the mass media.

Abstract
Low measles, mumps and rubella (MMR) immunization levels in European children highlight the importance of identifying determinants of parental vaccine uptake to implement policies for increasing vaccine compliance. The aim of this paper is to identify the main factors associated with partial and full MMR vaccination uptake in European parents, and combine the different studies to obtain overall quantitative measures. This activity is included within the ESCULAPIO project, funded by the Italian Ministry of Health. ORs and CIs were extracted, sources of heterogeneity explored and publication bias assessed. Forty-five papers were retrieved for the qualitative study, 26 of which were included in the meta-analysis. The following factors were associated with lower MMR vaccine uptake: misleading knowledge, beliefs and perceptions on vaccines (OR 0.57, CI 0.37-0.87); negative attitudes and behaviors toward vaccination (OR 0.71, CI 0.52-0.98); demographic characteristics, such as different ethnicity in Southern populations (OR 0.44, CI 0.31-0.61), higher child's age (OR 0.80, CI 0.76-0.85); low socio-economic status (OR 0.64, CI 0.51-0.80), especially low income (OR 0.39, CI 0.25-0.60) and education (OR 0.64, CI 0.48-0.84), high number of children (OR 0.54, CI 0.42-0.69), irregular marital status (OR 0.80, CI 0.66-0.96). The factors explaining heterogeneity were country location, administration modality, collection setting and responses reported on MMR alone or in combination. Findings from this study suggest policy makers to focus communication strategies on providing better knowledge, correct beliefs and perceptions on vaccines, and improving attitudes and behaviors in parents; and to target policies to people of ethnic minority from Southern Europe, low educated and deprived, with higher number of children and non-married marital status.

Abstract
The Adolescents Surveillance System for Obesity prevention (ASSO) Project aimed at developing standardized and web-based tools for collecting data on adolescents' obesity and its potential determinants. This has been implemented and piloted in the local area of Palermo city, Italy. The aim of the present study is to provide an overview of the Project's design, implementation, and evaluation, highlighting all the aspects for a potential scale-up of the surveillance system on the whole national territory and abroad, as a sustainable and effective source of data.The overall structure and management, the ASSO-toolkit, the ASSO-NutFit software, and all developed and used procedures for recruiting, training, and data collecting/analyzing are addressed. An interim evaluation has been performed through a feasibility study; a final Project evaluation has been performed reporting the Strengths, Weaknesses, Opportunities, and Threats (SWOT) and the attributes that a surveillance system should have.This article provides a detailed overview of the Project and highlights that ASSO can be considered a valid, logical, coherent, efficient, and sustainable surveillance system that is consistent with countries' needs and priorities.The system developed by the ASSO Project provides high-quality data and complies with several characteristics typical of a suitable surveillance system. It has a potential of being adopted within the National Health Service and other countries' Health Services for monitoring adolescents' obesity and its determinants, such as food intakes, behaviors, physical activity, and fitness profiles.

Abstract
The purpose of this investigation was to study the viral aetiology of influenza-like illness (ILI) and acute respiratory tract infection (ARTI) among patients requiring intensive care unit admission. A cross-sectional retrospective study was carried out in Sicily over a 4-year period. A total of 233 respiratory samples of patients with ILI/ARTI admitted to intensive care units were molecularly analyzed for the detection of a comprehensive panel of aetiologic agents of viral respiratory infections. About 45% of patients was positive for at least one pathogen. Single aetiology occurred in 75.2% of infected patients, while polymicrobial infection was found in 24.8% of positive subjects. Influenza was the most common aetiologic agent (55.7%), especially among adults. Most of patients with multiple aetiology (76.9%) were adults and elderly. Mortality rates among patients with negative or positive aetiology did not significantly differ (52.4% and 47.6%, respectively). Highly transmissible respiratory pathogens are frequently detected among patients with ILI/ARTI admitted in intensive care units, showing the occurrence of concurrent infections by different viruses. The knowledge of the circulation of several types of microorganisms is of crucial importance in terms of appropriateness of therapies, but also for the implication in prevention strategies and hospital epidemiology.

Abstract
A growing or compressed thin elastic sheet adhered to a rigid substrate can exhibit a buckling instability, forming an inward hump. Our study shows that the strip morphology depends on the delicate balance between the compression energy and the bending energy. We find that this instability is a first-order phase transition between the adhered solution and the buckled solution whose main control parameter is related to the sheet stretchability. In the nearly unstretchable regime, we provide an analytic expression for the critical threshold. Compressibility is the key assumption which allows us to resolve the apparent paradox of an unbounded pressure exerted on the external wall by a confined flexible loop.

Abstract
BACKGROUND ESCULAPIO is a multicenter project, funded by the Italian Centre for Disease Prevention and Control, aimed at implementing communication strategies to improve vaccination knowledge and attitudes among different target populations. OBJECTIVE The objective of the Sicilian research unit was, in the first phase, to identify, through systematic literature revision, which vaccination determinants play a role in the uptake of recommended vaccines included in the Italian Vaccination Plan. DESIGN A systematic literature review was carried out on studies describing the determinants underlying pneumococcal and meningococcal vaccination uptake. The analysis was limited to papers published in English from 2000 to date. RESULTS A total of 188 (meningococcal) and 731 (pneumococcal) papers were found. After selection by publication data, country (Europe), article type (original article), target population (healthy subjects), 7 (meningococcal) and 4 ( pneumococcal) manuscripts were finally included in the analysis. For meningococcal vaccination a better socioeconomic status is related to vaccination acceptance, whereas distance from immunization service is a negative determinant. For pneumococcal vaccination the determinants related to vaccination uptake are older parental age and a strong vaccine recommendation. Conversely, when the vaccine needs to be paid for, a refusal is more likely. CONCLUSIONS Our results show that payment for vaccination is a major barrier and communication about meningococcal and pneumococcal vaccination should be targeted towards specific population groups, especially through the counseling activities by health professionals.

Abstract
BACKGROUND A new web-based food frequency questionnaire (the ASSO-FFQ) was developed within the ASSO Project funded by the Italian Ministry of Health. OBJECTIVE The aim of the present study is to assess the validity of the ASSO-FFQ at food groups, energy, and nutrients level. DESIGN AND SUBJECTS The validation study compared the ASSO-FFQ against a weighted food record (WFR) measuring foods, beverages and supplements intake, compiled during the week following the ASSO-FFQ administration. Ninety-two subjects aged 14-17, recruited from secondary schools in Palermo (Italy), completed the ASSO-FFQ and WFR. The intake of 24 food groups, energy, and 52 nutrients were taken as main outcomes. Tests for paired observations, Spearman and Pearson's correlation coefficients (cc), kappa statistics and classification in quintiles, Bland-Altman plots and multiple regressions, on untransformed and transformed data were used for the statistical analysis. RESULTS High cc (≥0.40) were found for soft drinks, milk, tea/coffee, vegetables, and lactose; fair energy-adjusted cc (0.25-0.40) for water, alcoholic drinks, breakfast cereals, fishery products, savory food, fruit juice, eggs, and 19 nutrients. The subjects classified in the same or adjacent quintile for food groups ranged from 40% (alcoholic drinks) to 100% (dried fruit); for energy and nutrients from 43% (phosphorus, thiamin, niacin) to 77% (lactose). Mean differences were not significant for water, soft drinks, meat, sweets, animal fats, milk and white bread, and vitamin B12 and folate. Limits of Agreement were broad for all food groups and nutrients. School, gender, alcohol consumption and between meals mainly affected most food groups' intake differences. Gender stratification showed females had increased Pearson's cc for energy and 28 nutrients, such as almost all fats, carbohydrates, vitamins and minerals. CONCLUSIONS The ASSO-FFQ could be applied in epidemiological studies for the assessment of dietary consumption in adolescents to adequately rank food, energy and nutrient intakes at a group level.

Abstract
OBJECTIVES to assess the trends of foodborne diseases in respect of the abolition of food handler certification by Italian Regions. DESIGN rates of foodborne diseases recorded before and after the abolition of food handler certification were compared. SETTING AND PARTICIPANTS the study included notifications collected in Italy through the national infectious disease surveillance system between 1996 and 2009. MAIN OUTCOME MEASURES annual rates of seven main foodborne diseases. RESULTS a significant reduction in notifications of foodborne diseases occurred in most Italian Regions in the years after the abolition of the food handler certification. CONCLUSIONS the abolition of food handler certification coincided with no increase in the overall estimated incidence of foodborne diseases in the Italian population. Furthermore, the temporal and spatial patterns of notification rates suggest the possibility that other key factors have contributed to this result, including the heterogeneity of the surveillance system performance.

Abstract
Background A new food frequency questionnaire (FFQ) has been recently developed within the Italian Adolescents and Surveillance System for the Obesity prevention (ASSO) Project; it was found to be appropriate for ranking adolescents in food and nutrient levels of intake. The aim of this study was to assess the relative and absolute reproducibility of the ASSO-FFQ for 24 food groups, energy and 52 nutrients. Methods A test-retest study was performed on two ASSO-FFQs administered one month apart of each other to 185 adolescents, aged 14–17 and attending secondary schools in Palermo (Italy). Wilcoxon test assessed differences in median daily intakes between the two FFQs. Agreement was evaluated by quintiles comparison and weighted kappa. Intraclass Correlation Coefficients (ICC) and Bland-Altman method assessed the relative and absolute reliability respectively. Results Significant difference (p < 0.05) in median intakes was found only for bread substitutes, savoury food, water, soft drinks, carbohydrates and sugar. The subjects classified into the same or adjacent quintiles for food groups ranged from 62% (white bread) to 91% (soft drinks); for energy and nutrients from 64% (polyunsaturated fatty acids) to 90% (ethanol). Mean values of weighted kappa were 0.47 and 0.48, respectively for food groups and nutrients. Fair to good ICC values (>0.40) were assessed for thirteen food groups, energy and forty-three nutrients. Limits of Agreement were narrow for almost all food groups and all nutrients. Conclusions The ASSO-FFQ is a reliable instrument for estimating food groups, energy and nutrients intake in adolescents.

Abstract
Due to median vaccination coverage far from elimination level, Italy is still an European country with high number of measles cases per million of people. In this study we explored potential socioeconomic, medical and demographic factors which could influence the propensity of family members for measles vaccination schedule. A cross-sectional study was performed through a questionnaire administered to the parents of children who received the first dose of MMR vaccine in two different vaccination centers in the Palermo area from November 2012 to May 2013. Overall, the role played by internet (OR 19.8 P = 0.001) and the large number of children in a family (OR 7.3 P ≤ 0.001) were the factors more associated to be unvaccinated, whereas the birth order of the child (OR 0.3 P = < 0.05 for the oldest children vs. the closer young one) and reporting a lack of MMR vaccination as a "personal decision" (OR 0.19 P ≤ 0.01) inversely correlated with the risk of quitting vaccination. These findings can be useful for a better knowledge of disaffection to vaccination practice in local settings and could contribute to improve and maintain timely uptake, suggesting approaches to optimize the uptake of MMR tailored to the needs of local populations.

Abstract
Although influenza vaccination is recognized to be safe and effective, recent studies have confirmed that immunization coverage among health care workers remain generally low, especially among medical residents (MRs). Aim of the present multicenter study was to investigate attitudes and determinants associated with acceptance of influenza vaccination among Italian MRs. A survey was performed in 2012 on MRs attending post-graduate schools of 18 Italian Universities. Each participant was interviewed via an anonymous, self-administered, web-based questionnaire including questions on attitudes regarding influenza vaccination. A total of 2506 MRs were recruited in the survey and 299 (11.9%) of these stated they had accepted influenza vaccination in 2011-2012 season. Vaccinated MRs were older (P = 0.006), working in clinical settings (P = 0.048), and vaccinated in the 2 previous seasons (P<0.001 in both seasons). Moreover, MRs who had recommended influenza vaccination to their patients were significantly more compliant with influenza vaccination uptake in 2011-2012 season (P<0.001). "To avoid spreading influenza among patients" was recognized as the main reason for accepting vaccination by less than 15% of vaccinated MRs. Italian MRs seem to have a very low compliance with influenza vaccination and they seem to accept influenza vaccination as a habit that is unrelated to professional and ethical responsibility. Otherwise, residents who refuse vaccination in the previous seasons usually maintain their behaviors. Promoting correct attitudes and good practice in order to improve the influenza immunization rates of MRs could represent a decisive goal for increasing immunization coverage among health care workers of the future.

Abstract
Introduction: Collagenous colitis (CC) is a rare condition that is known to complicate inflammatory bowel diseases, but its relationship with celiac disease (CD) is more controversial. Aims: To report a case of CC that developed in a patient with CD and was manifested by rectal erosions at onset. Case report: A 46-year-old woman was diagnosed with CD and placed on a gluten-free diet. After an initial phase of improvement, her diarrhea resumed, and she began to lose weight. Despite strict adherence to the diet, the patient's diarrhea worsened. One year after diagnosis, colonoscopy was performed and mucosal biopsies were collected, but the findings were inconclusive. Two months later, the previously watery diarrhea became bloody, and a second colonoscopy was performed. Histological examination of the biopsy specimens revealed rectal erosions and CC. The patient was treated with oral prednisone plus mesalazine for 6 weeks, and her symptoms immediately disappeared. Mesalazine was continued, and the prednisone was then gradually replaced with budesonide. Six months after the CC diagnosis, the patient was asymptomatic, and a second colonoscopy revealed no macroscopic or microscopic signs of CC. She continues to take mesalazine and budesonide. An attempt to taper the dosage of the latter drug from 6 to 3 mg/day caused the reappearance of the diarrhea. Conclusion: CC is rarely associated to CD and can cause bloody diarrhea. Excellent results were obtained in this case with prednisone plus mesalazine followed by maintenance therapy with budesonide plus mesalazine.

Abstract
Spirometry plays an important role in occupational respiratory health surveillance programs. However, when not performed correctly, the values obtained can be misleading, resulting in misclassification of the workers' health status. Studies carried out in Italy have shown that spirometries recorded by occupational physicians often do not comply with quality criteria for recording FEV1 and FVC, according to joint statements on lung function testing for the American Thoracic Society and the European Respiratory Society, issued in 2005. For this reason, they are useless for the purposes of their execution. Compliance with ATS/ERS statements is essential to assure that spirometry results are beneficial for the monitoring of workers' health.

Abstract
BACKGROUND Legislation in Italy concerning health, safety and prevention at the workplace recently established a new data communication standard OBJECTIVES The findings are reported of a specific survey on 18 Local Health Units (ASL) over the entire Italian territory, aimed at identifying the critical points in data management and analyze the available information. METHODS The occupational health physician for each company must collect and transmit information on the number of workers submitted to health surveillance protocols to the Local Health Unit. Information must be divided by risk factor and gender Local health Units then transmit the data to the Regions and finally to the Italian National Institute for Occupational Safety and Prevention (ISPESL). RESULTS A sample of 22.977 companies was studied, providing information on about 410,009 workers undergoing health surveillance protocols. Carrying or moving heavy loads, exposure to noise, VDU and chemical substances were the most frequent risk factors. The difference between genders was significant in risk allocation, with exposures to VDU and biological agents prevalently among females. CONCLUSIONS The information thus collected suffered from a lack of data organization and completeness in the sample under study, but nevertheless provides preliminary evidence of a map of occupational risks on a national basis, confirming the potential for the new law (D.Lgs 81/2008) to investigate health safety and prevention at the workplace.

Abstract
The loss of sensitization over time, the involvement of a different pathogenetic mechanism and the poor sensitivity of diagnostic tests have been included among the causes of a non IgE-mediated anaphylaxis triggered by an insect sting. To provide further insight into this topic we describe the case of a patient suffering from urticaria pigmentosa, anaphylactic shock due to a Vespid sting and monosensitive to Polistes dominulus venom, who was previous diagnosed with non-IgE mediated insect sting anaphylaxis in subjects with urticaria pigmentosa. Therefore ultra-rush specific immunotherapy using an acqueous Polistes dominulus venom extract was performed over two mornings until a total dose of 100mcg was reached without any side effects. Presently the patient is undergoing maintenance therapy with a depot Polistes dominulus venom extract at 4-weekly intervals and is free of side effects. In conclusion, despite the high cross-reactivity among the venoms of the various species of Polistes, recent evidence of a selective specificity unique to European Polistes allergens raises the problem of the need to make the American Polistes venom as well as that of Polistes dominulus (a very common insect in Europe) available both for diagnostic and therapeutic purposes. Besides the fact that the presence of urticaria pigmentosa alone could have explained the anaphylactic reaction to the aspecific stimulation triggered by the venom, this case history also demonstrates that omitting to perform skin tests for Polistes dominulus venom would have led to the same misdiagnosis of non IgE-mediated anaphylaxis and served only to further delay commencing specific immunotherapy.

Abstract
The Helfrich-Hurault effect is a phase transition that occurs in samples of cholesteric or smectic liquid crystals subject to external electric or magnetic fields. In this paper we analyze the Helfrich-Hurault effect of smectic-A liquid crystals in an electrostatic field taking into account the complete electromechanical coupling. A comparison is made with the results already obtained for the partially coupled case where one takes into account only the effect of the field on the crystal configuration and considering that field unaffected.

Abstract
BACKGROUND Severity of a previous reaction, adult age, male gender and honeybee sting are risk factors for severe systemic reactions after hymenoptera stings. The aim of the study was to assess the association between the Vespa crabro sting and severe systemic reactions. METHODS One hundred fifty seven hymenoptera allergic patients with a positive case history for systemic reactions were selected on the basis of unequivocal identification of the stinging insect. In 97 patients the culprit insect was Vespula spp., in 35 was Vespa crabro in the remaining 25 patients was Apis mellifera. The relative risk for a life-threatening reactions after a sting was evaluated for each hymenoptera species. RESULTS While the percentage of life-threatening reactions was similar both in Apis mellifera (24%) and in Vespula spp. Allergic patients groups (27.8%), a very high prevalence (81.2%) was documented in Vespa crabro allergic patients group. The relative risk for life-threatening reactions after a Vespa crabro sting was about three times higher (RR = 2.74--CI 95% 1.93-3.89--R < 0.0001) than it was for a honeybee or yellow jacket sting. The increase of the risk for life-threatening reactions after a Vespa crabro sting was independent from the age of patients. CONCLUSION Vespa crabro sting seems to be a new risk factor for life-threatening reactions after hymenoptera sting.
