RESUMEN
BACKGROUND: The presence in Italy of a significant foreign population (5-6 million including both formally residents and not officially registered ones) introduces significant transformations in the Italian demography with important challenges on ensuring fundamental rights including work, education and above all, health. Access to healthcare. Issues common to the entire migrant population concern the difficulty of accessing the health system of the host country due to the lack of knowledge of its rules and its functioning, the linguistic and cultural barriers and the distrust towards a system that is not recognized as his own, as well as the difficulties and misunderstandings encountered in the relationship with health professionals. Religion, culture and gender may even increase these difficulties. Conlusion and future perspective. Culture and religion should be taken into account when designing and implementing healthcare services and healthcare workers need to be trained in acknowledging these challenges. The National Health Service should become more sensitive to the increasing cultural and religious pluralism of patients starting with investing more in the training of health professionals.

BACKGROUND: During the COVID-19 pandemic, migrants arriving in host countries irregularly have not infrequently been perceived as increasing the COVID-19 burden. Italy is a transit and destination country for migrants who cross the Central Mediterranean route and, during the pandemic, all migrants who landed on Italian shores were COVID-19 tested and quarantined. Our study aimed to investigate the impact of the SARS-CoV-2 infection among migrants who landed on the Italian coasts by analyzing both incidence and health outcomes. METHODS: A retrospective observational study has been designed. The population of interest was represented by 70,512 migrants (91% male, 99% <60 years old) who landed in Italy between January 2021 and 2022. SARS-CoV-2 incidence rate per 1,000 (with 95%CI) in migrants and the resident population in Italy of the corresponding age group was computed. The incidence rate ratio (IRR) was used to compare the incidence rates in migrants and the resident population. RESULTS: 2,861 migrants out of those landed in Italy during the observation period tested positive, with an incidence rate of 40.6 (39.1-42.1) cases per 1,000. During the same period, 177.6 (177.5-177.8) cases per 1,000 were reported in the resident population, with an IRR of 0.23 (0.22-0.24). 89.7% of cases were male and 54.6% belonged to the 20-29 age group. 99% of cases reported no symptoms, no relevant comorbidities were reported and no cases were hospitalized. CONCLUSIONS: Our study found a low rate of SARS-CoV-2 infection in migrants reaching Italy by sea with an incidence rate that is roughly a quarter of that of the resident population. Thus, irregular migrants who arrived in Italy during the observation period did not increase the COVID-19 burden. Further studies are needed to investigate possible reasons for the low incidence observed in this population.

Culture, religion and health are closely intertwined, profoundly affecting people's attitudes and behaviors as well as their conception and experience of illness and disease. In order to analyze the impact of religion in the current COVID-19 pandemic, we performed a literature review investigating both the scientific and grey literature on the topic. COVID-19 outbreaks reported in pilgrimages and religious ceremonies around the world-especially in the first wave of the pandemic wave-and the role played by religion in conveying culturally sensitive information about COVID-19 are some of the evidence we reviewed. Our research highlights how religions have represented, on the one hand, a risk for the spread of the virus and, on the other, a precious opportunity to engage people, and in particular minorities, in fighting the pandemic. To overcome this pandemic and to be prepared for similar ones in the future, scientists, politicians and health professionals should acknowledge the role that culture and religion play in people's lives and how it can assist in tackling complex health challenges.

Migration is a longstanding, growing global phenomenon. As a social determinant of health, migration can lead to health inequities between people on the move and host populations. Thus, it is imperative that there is a coordinated effort to advance migration- and health-related goals. WHO has a specific remit to support evidence-based decision-making in its Member States. As part of that remit, WHO Europe presents this Framework for Refugee and Migrant Health Research in the WHO European Region. It is designed as a starting point for debating and analysing a broad range of options and approaches to help inform a WHO global research agenda on health and migration. This is important because refugee and migrant health research is a complex interdisciplinary field that is expanding in a fast-changing socio-political environment. The Framework is intended for all stakeholders involved: academic, civil society organisations, refugees, migrants, policy-makers, healthcare providers, educators and funders. It is developed by academics in consultation with these stakeholder groups. It reflects on three specific interrelated dynamics in research practice. These are (i) research prioritisation; (ii) study samples and (iii) research design. The Framework offers recommendations to consider for each one of these. It elucidates the value of involving refugees and migrants in research and research agendas and the need to develop an ecosystem that will support and sustain participatory, interdisciplinary, transdisciplinary and inter-sectoral projects.

Long COVID-19 is a term used to describe the symptomatic sequelae that develop after suffering from COVID-19. Very few studies have investigated the impact of COVID-19 sequelae on employment status. The aim of this research was to characterise sequelae of COVID-19 in a population of workers who tested positive for COVID-19, with a follow-up within one year of the acute illness, and to analyse the possible association between this and changes in the workers' occupational status. In this retrospective cohort study, a questionnaire was administered to 155 workers; descriptive, univariate (chi-square tests), and multivariate (logistic regression model) analyses were carried out. The mean age was 46.48 years (SD ± 7.302); 76 participants were males (49.7%), and 33 participants reported being current smokers (21.3%). Overall, 19.0% of patients reported not feeling fully recovered at follow-up, and 13.7% reported a change in their job status after COVID-19. A change in occupational status was associated with being a smoker (OR 4.106, CI [1.406-11.990], p = 0.010); hospital stay was associated with age > 46 years in a statistically significant way (p = 0.025) and with not feeling fully recovered at follow-up (p = 0.003). A persistent worsening in anxiety was more common in women (p = 0.028). This study identifies smoking as a risk factor for workers not able to resume their job; furthermore, occupational physicians should monitor mental health more closely after COVID-19, particularly in female workers.

A prodigious increment of scientific evidence in both preclinical and clinical studies is narrowing a major gap in knowledge regarding sex-specific biological responses observed in numerous branches of clinical practices. Some paradigmatic examples include neurodegenerative and mental disorders, immune-related disorders such as pathogenic infections and autoimmune diseases, oncologic conditions, and cardiovascular morbidities. The male-to-female proportion in a population is expressed as sex ratio and varies eminently with respect to the pathophysiology, natural history, incidence, prevalence, and mortality rates. The factors that determine this scenario incorporate both sex-associated biological differences and gender-dependent sociocultural issues. A broad narrative review focused on the current knowledge about the role of hormone regulation in gender medicine and gender peculiarities across key clinical areas is provided. Sex differences in immune response, cardiovascular diseases, neurological disorders, cancer, and COVID-19 are some of the hints reported. Moreover, gender implications in occupational health and health policy are offered to support the need for more personalized clinical medicine and public health approaches to achieve an ameliorated quality of life of patients and better outcomes in population health.

BACKGROUND: Despite mergers have increasingly affected hospitals in the recent decades, literature on the impact of hospitals mergers on healthcare quality measures (HQM) is still lacking. Our research aimed to systematically review evidence regarding the impact of hospital mergers on HQM focusing especially on process indicators and clinical outcomes. METHODS: The search was carried out until January 2020 using the Population, Intervention, Comparison and Outcome model, querying electronic databases (MEDLINE, Scopus, Web Of Science) and refining the search with hand search. Studies that assessed HQM of hospitals that have undergone a merger were included. HQMs were analyzed through a narrative synthesis and a strength of the evidence analysis based on the quality of the studies and the consistency of the findings. RESULTS: The 16 articles, included in the narrative synthesis, reported inconsistent findings and few statistically significant results. All indicators analyzed showed an insufficient strength of evidence to achieve conclusive results. However, a tendency in the decrease of the number of beds, hospital staff and inpatient admissions and an increase in both mortality and readmission rate for acute myocardial infarction and stroke emerged in our analysis. CONCLUSIONS: In our study, there is no strong evidence of improvement or worsening of HQM in hospital mergers. Since a limited amount of studies currently exists, additional studies are needed. In the meanwhile, hospital managers involved in mergers should adopt a clear evaluation framework with indicators that help to periodically and systematically assess HQM ascertaining that mergers ensure and primarily do not reduce the quality of care.

Adenoid cystic carcinoma (ACC) of the breast is a very rare neoplasm. It presents a triple-negative phenotype in most cases, but its prognosis is generally considered to be better than other breast cancers with the same immunohistochemical pattern. Due to its controversial features, no data are available in the literature regarding a consensus approach for ACC treatment, especially for subtypes with worse prognosis like solid basaloid ACC. We present for the first time a rare case of ACC with multifocal presentation treated with breast-conservative surgery and intraoperative electron radiotherapy, thus supporting this treatment of ACC in selected patients like young women affected by the solid basaloid variant who commonly present a worse prognosis. In this case, no local or systemic recurrence was detected after 30 months of follow-up.
Plain language summary Breast cancer is a large group of tumors with different and specific features. Because of its variety, no univocal guidelines are available to medical doctors for the treatment of this disease, especially for the rarest presentations. This is the case for breast adenoid cystic carcinoma, a rare tumor which accounts for less than 0.1% of all breast cancers and about which few instructions for its therapeutic approach or prognosis are described in the literature. This case report describes our experience using partial breast resection in combination with a specific protocol of intraoperative radiation for the treatment of an aggressive variant of breast adenoid cystic carcinoma. Good cosmetic results and no recurrence of the disease were shown, suggesting that a conservative approach could avoid unnecessary total breast resection as supported by some previous authors.

From the beginning of the COVID-19 pandemic, attention was raised to protect vulnerable populations, including migrants and refugees (M&R), with the claim to leave no one behind in the pandemic response. In particular, concern was expressed in M&R's reception centres since several COVID-19 outbreaks had been observed in Europe. Our study aimed to evaluate the impact of COVID-19 in the Italian reception system in the first pandemic wave in terms of incidence and health outcomes. A national survey focusing on the lockdown period of early 2020 was performed among reception centre managers. The survey achieved reaching around 70% of reception facilities and hosts. A national cumulative incidence of 400 positive cases per 100,000 and a north-south geographical gradient were observed. Sixty-eight facilities out of the 5038 participating in the survey reported confirmed cases and few COVID-19 clusters were detected especially in accommodations with the highest facility saturation index. Positive migrants were hospitalised in 25.9% of cases and no COVID-19 related deaths were observed. The study highlighted a cumulative incidence of cases and a geographical distribution similar to that of the general resident population, showing a global COVID-19 resilience in the Italian reception system in the period of observation, well beyond the expectations.

BACKGROUND: While many studies focus on specific aspects of Unaccompanied Migrant Minors' (UMMs) health, especially mental well-being, there is a lack of tools comprehensively assessing their needs. To fill this gap, we developed and validated a questionnaire to thoroughly assess unAccompaniEd miGrant mInorS' physical, psychological, legal, spiritual, social and educational needs (AEGIS-Q). METHODS: This work consisted of three stages. The first one involved an extensive literature review. Given the results of the review, a first draft of the questionnaire was developed and submitted to a panel of experts for validation (Delphi method-second stage). During the third stage, the final version of the questionnaire was pilot-tested in a sample of 18 UMMs. RESULTS: The questionnaire, drafted based on the results of the review, consisted of sections covering personal data, migration profile, physical health needs and access to healthcare, psychological needs, legal needs, spiritual needs and educational and social needs of UMMs. After two Delphi rounds, the final version of the questionnaire, consisting of 83 questions, was structured. The pilot study had a response rate of 89-100%. We found substantial reliability for most of the sections in the questionnaire, including physical health (α=0.652), legal (α=0.781), and educational and social (α=0.614) needs. The questions regarding psychological needs had very high reliability (α=0.860). CONCLUSIONS: The questionnaire offers a useful sharable tool to assess and monitor UMMs' needs, helping the reception system to better know and meet their needs and implement the taking in charge.

OBJECTIVES: To evaluate interstitial lung disease associated with systemic sclerosis (SSc-ILD) and its changes during treatment by using quantitative analysis (QA) compared to semi-quantitative analysis (semiQA) of chest computed tomography (CT) scans. To assess the prognostic value of QA in predicting functional changes. MATERIALS AND METHODS: We retrospectively selected 35 consecutive patients with SSc-ILD with complete pulmonary functional evaluation, Doppler-echocardiography, immunological tests, and chest CT scan at both baseline and follow-up after immunosuppressive therapy. CT images were analyzed by two chest radiologists for semiQA and by a computational platform for texture analysis of ILD patterns (CALIPER) for QA. Concordance between semiQA and QA was tested. Traction bronchiectasis severity was scored. Analysis of ROC curves was performed. RESULTS: Seventy CT scans were analyzed and QA failed in 4/70 scans. Thus, the final population included 31/35 patients (51.3±12.1 years). QA had a weak-to-good concordance with semiQA (ICC reticular:0.275; ICC ground-glass:0.667) and QA correlated better than semiQA (r = -0.3 to -0.74 vs r = -0.3 to -0.4) with functional parameters. Both methods correlated with traction bronchiectases score and pulmonary artery diameter at CT. A pulmonary artery diameter ≥29mm distinguished patients with lower lung volumes and ILD extent greater than 39% (p<0.001). Changes in QA patterns during treatment were not accurate (AUC: 0.50 to 0.70; p>0.05) in predicting disease progression as assessed by functional parameters, whereas variation in total lung volume at QA accurately predicted changes in the composite functional respiratory endpoint with FVC% and DLco% (AUC = 0.74; 95%CI: 0.54 to 0.93; p = 0.03). CONCLUSIONS: Pulmonary QA of CT images can objectively quantify specific patterns of ILD changes during treatment in patients with SSc-ILD. Changes in QA patterns do not correlate with functional changes, but variation in total lung volume at QA accurately predicted changes in the composite functional respiratory endpoint with FVC% and DLco%. Pulmonary artery diameter at CT reflects the interstitial involvement, identifying patients with more severe prognosis.

BACKGROUND: Optimization of chemotherapy regimens in the treatment of multiple myeloma (MM) has led to increase the frequency of cases with complete response (CR). Nonetheless, many MM patients still experience relapse, suggesting that CR represents a suboptimal response criteria, and that new therapeutic strategies are needed after single transplant. However, the role of double autologous stem cell transplant (ASCT) as new adjunctive strategy remains to be elucidated. Indeed, we investigated the role of minimal residual disease (MRD) and log-reduction of plasma cells (PCs) as predictors of outcome and in quantifying the degree of tumor reduction after any ASCT. METHODS: MRD and log-reduction were assessed by a six-color flow cytometry (FC) at different time-points: post induction, post first-, and post-second ASCT. RESULTS: A significant difference was evidenced among the three time points for both log-reduction (P < 0.001) and MRD (P = 0.005). MRD levels after double ASCT were lower than MRD levels achieved after single ASCT (P = 0.005) and after induction (P < 0.001). Frequency of MRD positive patients after double ASCT was significantly lower rather than after the first ASCT (P = 0.008) and after induction (P = 0.004). Interestingly, a significant reduction of PFS was observed in patients with an unfavorable-risk cytogenetic (P < 0.001) and patients with MRD over 0.01% (P = 0.001) as well as log-reduction lower than 2.57 (P = 0.018) after double ASCT. CONCLUSIONS: Our results show that a better clearance of myeloma cells is observed after the double ASCT, and a longer PFS is associated with a lower MRD. © 2018 International Clinical Cytometry Society.

OBJECTIVE: To investigate whether miscarried embryo/fetal crown rump length (CRL) measurement may yield a practical application for predicting a conclusive result at the cytogenetic analysis of miscarriage tissue. Our study might help in improving the cytogenetic method, the results of which may be affected by maternal cell contamination (MCC). In particular, we aimed at establishing whether the miscarried embryo/fetal CRL measurement shows accuracy in predicting the possibility of MCC and the scan cut-off value useful to this purpose and, as a result, suggest a multi-step procedure for the genetic ascertainment. METHODS: Women experiencing at least two miscarriages of less than 20 weeks size at the Pregnancy Loss Unit at Fondazione Policlinico A. Gemelli underwent a scan before surgery. The CRL value was recorded. After the dilatation and courettage (D&C) procedure, miscarriage tissue was processed through the proposed multi-step procedure before performing oligo-nucleotide-based and SNP (single nucleotide polymorphisms)-based comparative genomic hybridization (CGH+SNP) microarray analysis. RESULTS: 63 women and 63 miscarriages met the criteria. By using the Receiving Operator Characteristic (ROC) curves, CRL showed an AUC of 0.816 (95%CI:0.703-0.928,p<0.001). A CRL≥24.5 mm cut-off value showed a higher positive likelihood ratio (5.27) but, conversely, a higher negative likelihood ratio (0.64) in predicting the possibility of MCC. Microarray analysis was successful in the totality of cases in which the embryo/fetal origin of miscarriage tissues was proven. CONCLUSIONS: The 24.5 mm CRL value emerges as the most suitable cut-off enabling the identification of cases in which the embryo-fetal component can be isolated in the absence of MCC and the chromosomal array provide informative results.

OBJECTIVES: The first aim of our study was to compare the characteristics and comorbidities of patients with eating disorders between those who suffered from a childhood abuse and those who did not. Our second aim was to analyze the differences in the outcome of the psychodynamic therapy between abused and not abused patients. METHODS: Twenty-six adolescent patients with eating disorders were assessed. Adolescent were evaluated by a single expert psychiatrist by checklists and questionnaires: EDI 3, SCL 90, BIS11, Dissociative Experiences Scale, Global Assessment of Functioning, SCID II, and CTQ-Self control (SF). According to the results of CTQ-SF (cut-off ≥ 8), patients were divided into two groups: those who had experienced a history of abuse and those who had not. They underwent a psychodynamic psychotherapy and were assessed again after 12 months. RESULTS: Eleven patients (42.3%) had a history of abuse according to CTQ score. No significant differences were found in abused and not abused patients in their demographic, clinical, and comorbid characteristics (sex, age, type of eating disorder, comorbid impulse control, personality, and addictive disorders). Abused patients showed a significantly higher score in many scale. The psychotherapeutic intervention in patients with a history of abuse resulted only in a significant decrease in symptom checklist-90 (SCL-90) psychoticism dimension (p < 0.05), whereas in patients with no history of abuse a significant decrease was found for SCL-90 somatization, obsessive-compulsive and phobic anxiety dimensions, the SCL-90 Global Severity Index, the Eating Disorder Inventory-3 interceptive deficits, and the dissociative experience scale. CONCLUSION: Regarding the first aim of our study, we proved that history of abuse is not significantly related to patient comorbidities. Regarding our second aim, history of abuse was related to patient improvement only for psychotic symptoms; whereas patients who had not experienced an abuse improved in a variety of symptoms. Thus, abuse history can be considered as a negative prognostic factor for patients with eating disorders undergoing dynamic psychotherapy. However, this psychotherapy may have a role in preventing early psychotic disorders in patients with and without an history of abuse.
RESUMEN
Italy is witnessing relevant challenges in the field of prevention and control of vaccine-preventable diseases. The worrying and growing phenomenon of "vaccine-hesitancy" has contributed to the reduction of vaccination coverage, undermining goals reached thanks to vaccines introduction. The new Italian National Immunization Plan (NIP) 2017-2019 and the update of the list of Essential Care Levels (LEA), approved in the current year, extend the vaccination offer based on the latest scientific evidence with the introduction of new vaccines and the enlargement of target population. The decree-law containing urgent measures in immunization field issued in June 2017 represents a tool to achieve the goals reported in global and national immunization plans. Among others it has increased mandatory vaccinations from 4 to 10 and has made them compulsory for pre-school admission. Following the global and European vaccination goals, the priorities identified by the Italian NIP are to: maintain the polio-free status; pursue the elimination of measles and congenital rubella; ensure an active and free of charge vaccination offer, the access to services and the availability of vaccines; target hard to reach populations with low vaccination coverage; develop an institutional communication plan on vaccinations. Regarding the vaccination offer, the main novelties introduced by the NIP 2017-2019 include the introduction of: vaccines against N. meningitidis B, rotavirus and varicella in newborns; tetravalent meningococcal vaccine (ACWY135) and a booster dose of anti-polio in adolescents; pneumococcal vaccines (PCV13 + PPV23) and anti-Zoster in subjects aged sixty-five. Furthermore, the NIP 2017-2019 establishes to extend HPV vaccination to male adolescents. The cost of new vaccinations, funded by the National Health System, is about 100 million euros in 2017 but, thanks to the new vaccination schedule, it is estimated that approximately 200 million euros will be saved because of the annual reduction of direct costs of vaccine-preventable diseases. Furthermore, the NIP tries to act against the growing public skepticism in vaccines, proposing solutions to counteract the fall in vaccination coverage by promoting a culture of vaccination and the empowerment of both health workers and general population. In this perspective, the NIP proposes to promote institutional communication campaigns, based on transparency, conveying information about vaccines risks and benefits and the ethical and social value of vaccinations. It is further proposed to strengthen the training of healthcare professionals, jointly with disciplinary actions against physicians who do not recommend vaccinations. Particular attention is also placed on the implementation of vaccines registries for the homogenization of data recording that allows to evaluate and to monitor vaccine policies. The update of LEA, which include a list of services provided by SSN, has adopted the innovations of the NIP and overcomes the criticism of regional inequalities in vaccination offer guaranteeing the same offer all over the Italian country. In conclusion, the NIP 2017-2019 and the new LEA are fully integrated into the current epidemiological and cultural scenario. They envisage a supply of evidence-based vaccinations, ensuring a free, equal and uniform vaccination offer on a national scale and striving for the promotion of a culture of vaccination.

OBJECTIVE: Over the last few years, medical scholars have reported the significant association between recurrent pregnancy loss (RPL) and celiac disease (CD). Various pathogenic mechanisms underlying the pregnancy failure in CD have been suggested: among them the ability of anti-transglutaminase antibodies to impair the trophoblast invasiveness and endometrial endothelial cells differentiation and disrupt early placentation. CD shows a complex non-Mendelian pattern of inheritance, involving major histocompatibility complex (MHC) genes. The strongest effects are mapped to the classical human leukocyte antigen (HLA)-DQA1 and HLA-DQB1 genes. Specifically, the common haplotypes DQ2.5, DQ2.2, and DQ8 have been shown to increase CD risk by six-fold on average. MHC region contains genes with immunological functions and is responsible for the strongest association signals observed in most immune-mediated diseases. The aim of our study was to investigate the prevalence of the HLA-DQ2/DQ8 haplotypes in RPL, outside of CD. METHODS: The study population included women with history of RPL (≥3 spontaneous pregnancy losses) and women with at least two previous uncomplicated term pregnancies (control group, CTR). All women gave their informed consent to use their data for research purposes. RESULTS: 97 RPL women and 55 CTR were considered in the study. Mean age of the RPL sample was 37.7 (standard deviation, SD, 3.0; min 27; max 39). Mean age of the control group was 35.6 (SD 3.0; min 26years; m, max 38). A significantly increased prevalence of HLA-DQ2/DQ8 haplotype positivity was found in RPL population compared to control women (52.6% vs 23.6%; p<0.01). CONCLUSIONS: Our observations show for the first time a higher proportion of individuals HLA DQ2/DQ8 positive in women with RPL as compared to controls (and to general population estimates). Further studies are needed to better understand (i) the possible pathogenic mechanism to this observation; (ii) the clinical and therapeutic implications of our observation in order to provide a new approach to RPL couples.
