Omentum flap as a spacer before carbon ion radiotherapy for gynecological recurrences. A technical note

Re-irradiation of pelvic recurrent gynecological cancer is a challenge due to the proximity of high-radiation-sensitive organs, such as the bowel and the urinary tract. Hadrontherapy for re-irradiation emerges as a safe and effective treatment with a mild rate of morbidity of surrounding normal tissue. To improve the dose to the tumor, a prophylactic displacement of organs at risk is needed, and a multidisciplinary approach is recommended. In this technical note, we report a surgical technique of omentum spacer placement for patients enrolled for carbon ion radiotherapy as re-irradiation for recurrent gynecological tumors.

Small Paroxysmal Nocturnal Hemoglobinuria Clones in Autoimmune Hemolytic Anemia: Clinical Implications and Different Cytokine Patterns in Positive and Negative Patients

Autoimmune hemolytic anemia (AIHA) is characterized by immune mediated erythrocytes destruction by autoantibodies with or without complement activation. Additional pathologic mechanisms include cellular cytotoxicity, cytokline dysregulation, and inadequate bone marrow compensation with fibrosis/dyserythropoiesis. The latter resembles that of bone marrow failures, namely aplastic anemia and myelodysplastic syndromes. Paroxysmal nocturnal hemoglobinuria (PNH) clones are increasingly recognized in bone marrow failure syndromes, and their selection and expansion are thought to be mediated by immune mechanisms. In this study, we aimed to evaluate the prevalence of PNH clones in 99 patients with primary AIHA, and their correlations with disease features and outcomes. Moreover, in the attempt to disclose the physiopathology of PNH positivity in AIHA, serum levels of several immunomodulatory cytokines were tested. A PNH clone was found in 37 AIHA patients (37,4%), with a median size of 0.2% on granulocytes (range 0.03\u201385). Two patients showed a large clone (16 and 85%) and were therefore considered as AIHA/PNH association and not included in further analysis. Compared to PNH negative, PNH positive cases displayed a higher hemolytic pattern with adequate bone marrow compensation. AIHA type, response to therapy, complications and outcome were comparable between the two groups. Regarding cytokine levels, IFN-\u3b3 and IL-17 were lower in PNH positive vs. PNH negative AIHAs (0.3 \ub1 0.2 vs. 1.33 \ub1 2.5; 0.15 \ub1 0.3 vs. 3,7 \ub1 9.1, respectively, p = 0.07 for both). In PNH positive AIHAs, IFN-\u3b3 positively correlated with reticulocytes (r = 0.52, p = 0.01) and with the bone marrow responsiveness index (r = 0.69, p = 0.002). Conversely, IL-6 and IL-10 showed the same pattern in PNH positive and PNH negative AIHAs. IL-6 levels and TGF-\u3b2 positively correlated with clone size (r = 0.35, p = 0.007, and r = 0.38, p = 0.05, respectively), as well as with LDH values (r = 0.69, p = 0.0003, and r = 0.34, p = 0.07, respectively). These data suggest testing PNH clones in AIHA since their prevalence is not negligible, and may correlate with a prominent hemolytic pattern, a higher thrombotic risk, and a different therapy indication. PNH testing is particularly advisable in complex cases with inadequate response to AIHA-specific therapy. Cytokine patterns of PNH positive and negative AIHAs may give hints about the pathogenesis of highly hemolytic AIHA

Tackling TB in migrants arriving at Europe’s southern border

Over a quarter of the individuals diagnosed with tuberculosis [TB] in the European Union region are born outside of the area and the proportion has been increasing steadily. Italy is a low TB incidence country with over 50% of TB cases in the foreign-born population primarily due to the high numbers of migrants entering the country via land or sea. As a case study to evaluate the value of screening in newly arrived migrants, the EDETECT-TB project in Italy implemented and evaluated active TB screening in the migrant population at first reception centres to ensure early diagnosis to avoid further spread. Based on a cost-effectiveness analysis from a program provider perspective, a decision tree model allowed the assessment of the value for money of case finding by estimating the cost per case of active TB detected compared with the status quo of no screening. The analysis confirmed that early case detection is a cost-effective intervention in areas with migrants arriving from high TB risk settings. Targeted post-arrival early screening of high TB risk vulnerable new entrants to Italy has a potential role in reducing the spread of TB among migrants

Knowledge translation in challenging healthcare environments: The PIOPPO experience at the National Centre of Oncological Hadrontherapy (CNAO Foundation).

Knowledge translation is the ability to translate concepts and ideas effectively among different stakeholders, leading to innovation and new knowledge. Translating knowledge is particularly challenging in the healthcare sector, which has been experiencing a shift from a centralized and sequential model of value creation to a more distributed and open model, where various stakeholders (including patients) act as co-creators of the outcome. According to management as well as the medical literature, knowledge translation in healthcare has been mainly seen as the translation of scientific research into clinical practice. However, different types of knowledge translation emerge, such as when multidisciplinary teams need to work together on a joint medical project. In this situation, multiple backgrounds, competencies, skills, and emotional feelings of the different stakeholders are a compelling barrier that prevents the effective transfer and sharing of knowledge. This is why knowledge translation needs a set of enablers to facilitate the transfer, sharing, and creation of new knowledge, innovation, and ideas. This paper investigates such a perspective by analyzing the PIOPPO project from the National Centre of Oncological Hadrontherapy (CNAO Foundation) in Pavia, Italy. The CNAO is one of the few dual-beam Hadrontherapy centres in the world that provides a beam that is able to irradiate patients with protons or carbon ions to treat radioresistant tumours. The PIOPPO project is an experimental phase 2 trial involving preoperative chemotherapy and carbon ion therapy to treat resectable and borderline-resectable pancreatic adenocarcinoma. The stakeholders involved in the PIOPPO trial have different characteristics, both in terms of competencies and emotions. The PIOPPO multidisciplinary team includes highly skilled professionals from several disciplines, which are not all related to medicine (from oncologists to physicists, from biologists to surgeons). Pancreatic cancer patients are also involved while experiencing a challenging personal time. The paper analyses the knowledge translation flows, instruments, and issues among such different stakeholders

The Role of Virulence Factors in Neonatal Sepsis Caused by Enterobacterales: A Systematic Review.

Neonatal sepsis is a life-threatening condition with high mortality. Virulence determinants relevant in causing Gram-negative (GN) neonatal sepsis are still poorly characterized. A better understanding of virulence factors (VFs) associated with GN neonatal sepsis could offer new targets for therapeutic interventions. The aim of this review was to assess the role of GN VFs in neonatal sepsis. We primarily aimed to investigate the main VFs leading to adverse outcome and second to evaluate VFs associated with increased invasiveness/pathogenicity in neonates. MEDLINE, Embase, and Cochrane Library were systematically searched for studies reporting data on the role of virulome/VFs in bloodstream infections caused by Enterobacterales among neonates and infants aged 0-90 days. Twenty studies fulfilled the inclusion criteria. Only 4 studies reported data on the association between pathogen virulence determinants and neonatal mortality, whereas 16 studies were included in the secondary analyses. The quality of reporting was suboptimal in the great majority of the published studies. No consistent association between virulence determinants and GN strains causing neonatal sepsis was identified. Considerable heterogeneity was found in terms of VFs analysed and reported, included population and microbiological methods, with the included studies often showing conflicting data. This variability hampered the comparison of the results. In conclusions, pathogens responsible for neonatal sepsis are widely heterogenous and can use different pathways to develop invasive disease. The recent genome-wide approach needs to include multicentre studies with larger sample sizes, analyses of VF gene profiles instead of single VF genes, alongside a comprehensive collection of clinical information. A better understanding of the roles of virulence genes in neonatal GN bacteraemia may offer new vaccine targets and new markers of highly virulent strains. This information can potentially be used for screening and preventive interventions as well as for new targets for anti-virulence antibiotic-sparing therapies

Gastrointestinal Symptoms in Severe COVID-19 Children.

There are growing evidence of clinical manifestations other than acute respiratory syndrome in severe acute respiratory syndrome associated with coronavirus 2-infected children. In our multicenter retrospective analysis, we observed among 127 severe acute respiratory syndrome associated with coronavirus 2 positive children that the presence of gastrointestinal symptoms was more frequently associated with severe and critical phenotype (P = 0.029). Moreover, having gastrointestinal symptoms was more frequently reported in patients who developed cardiac impairment

Re-irradiation with carbon ion radiotherapy for pelvic rectal cancer recurrences in patients previously irradiated to the pelvis

Background/Aim: Re-irradiation of locally recurrent rectal cancer poses challenges due to the proximity of critical organs, such as the bowel. This study aimed at evaluating the safety and efficacy of re-irradiation with Carbon Ion Radiotherapy (CIRT) in rectal cancer patients with local recurrence. Patients and Methods: Between 2014 and 2018, 14 patients were treated at the National Center of Oncological Hadrontherapy (CNAO Foundation) with CIRT for locally recurrent rectal cancer. Results: All patients concluded the treatment. No G≥3 acute/late reaction nor pelvic infections were observed. The 1-year and 2-year local control rates were, 78% and 52%, respectively, and relapse occurred close to the bowel in 6 patients. The 1-year and 2-year overall survival rates were 100% and 76.2% each; while the 1-year and 2-year metastasis free survival rates were 64.3% and 43%. Conclusion: CIRT as re-irradiation for locally recurrent rectal cancer emerges as a safe and valid treatment with an acceptable rate of morbidity of surrounding healthy tissue
