The Ligurian HIV Network, based on HL7 CDA r2, is an Italian regional infrastructure for HIV surveillance and control. To expand this network to a European level, the alignment with the EHDS and the EEHRxF, which standardize EHR data exchange, becomes essential. EU-funded projects like XpanDH are developing HL7 FHIR IGs to support this framework. Therefore, the extension of the Ligurian HIV Network requires an architectural rethink, with the introduction of the HL7 FHIR format instead of CDA r2, ensuring compliance with European standards.

Abstract Background Acute pulmonary embolism (PE) is a life-threatening disease with specific risk factors among women. Systematic evaluation of contemporary quality of care and outcomes in women hospitalized with acute PE is needed. Methods The COPE Registry (COntemporary management of acute Pulmonary Embolism) is a nationwide registry that was run in Internal Medicine, Cardiology and Emergency Departments in Italy. Using data from the COPE Registry, we evaluated sex differences in acute management, medical therapies, in-hospital and 30-day mortality and major bleeding in 5,213 patients admitted for acute PE at 182 hospitals in Italy from 2018 to 2020. Results Women (n=2,728) were older than men (71.2 versus 66.6 years, P<0.001) and had different distribution of comorbidities, with dementia and severe renal failure being more prevalent (13.6 vs 6.4% and 6.1 vs 3.0%, respectively) and cancer, COPD and recent bed-rest less prevalent (15.2 vs 18.5% and 11.1 vs 14.5% and 23.5 vs 20.2%) in women than men. At presentation, PE was more severe in women than men in terms of hemodynamic instability (4.1 vs 2.7%), prevalence of right ventricle overload at echocardiography (64.5 vs 57%) and prevalence of sPESI=0 (29.4 vs 38.5%). Concerning the likelihood to receive evidence-based acute treatments for PE, women were more likely than men to receive reperfusion in the case of hemodynamic compromise at presentation after adjusting for age and dementia (63.1 vs 50.0%; OR 1.934, 95% CI 1.01-3.71), and to receive direct oral anticoagulants during hospitalization after adjusting for age, dementia and severe renal failure (50.9 vs 48.6%; OR 1.14, 95% CI 1.01-1.28); similar proportions of low-risk women and men were managed as outpatients or by short hospital stay (1.4% vs 1.4% and 8.6 vs 6.0%, respectively). In-hospital and 30-day mortality rates were not different in women and in men (3.7% versus 3.1% and 5.5 vs 4.8%), but PE-related mortality was higher in women than in men (2.1 vs 1.3%). The sex difference in PE-related mortality was no longer observed in after adjusting for age, hemodynamic instability and dementia (adjusted HR 1.20; 95% CI 0.77-1.88; P=0.415). Similar rates of early and delayed major bleedings occurred in women and in men, both at univariate analysis and after adjusting for age, creatinine clearance and use of thrombolysis. None of 22 pregnant women and 1 out of 204 women with estro-progestin associated PE died or experienced major bleeding. Conclusions Women hospitalized for acute PE in Italy received evidence-based acute treatments more commonly than men. The observed sex differences in PE-related mortality were mainly attributable to worse clinical profiles and older age. Women with sex-related risk factor for PE had favorable prognosis.

IntroductionThe human brain is an intricate structure composed of interconnected modular networks, whose organization is known to balance the principles of segregation and integration, enabling rapid information exchange and the generation of coherent brain states. Segregation involves the specialization of brain regions for specific tasks, while integration facilitates communication among these regions, allowing for efficient information flow. Several factors influence this balance, including maturation, aging, and the insurgence of neurological disorders like epilepsy, stroke, or cancer. To gain insights into information processing and connectivity recovery, we devised a controllable in vitro model to mimic and investigate the effects of different segregation and integration ratios over time.MethodsWe designed a cross-shaped polymeric mask to initially establish four independent sub-populations of cortical neurons and analyzed how the timing of its removal affected network development. We evaluated the morphological and functional features of the networks from 11 to 18 days in vitro (DIVs) with immunofluorescence techniques and micro-electrode arrays (MEAs).ResultsThe removal of the mask at different developmental stages of the network lead to strong variations in the degree of intercommunication among the four assemblies (altering the segregation/integration balance), impacting firing and bursting parameters. Early removal (after 5 DIVs) resulted in networks with a level of integration similar to homogeneous controls (without physical constraints). In contrast, late removal (after 15 DIVs) hindered the formation of strong inter-compartment connectivity, leading to more clustered and segregated assemblies.DiscussionA critical balance between segregation and integration was observed when the mask was removed at DIV 10, allowing for the formation of a strong connectivity among the still-separated compartments, thus demonstrating the existence of a time window in network development in which it is possible to achieve a balance between segregation and integration.

Brain disorders, encompassing a wide spectrum of neurological and psychiatric conditions, present a formidable challenge in modern medicine. Despite decades of research, the intricate complexity of the human brain still eludes comprehensive understanding, impeding the development of effective treatments. Recent advancements in microfluidics and tissue engineering have led to the development of innovative platforms known as "Brain-on-a-Chip" (BoC) i.e., advanced in vitro systems that aim to replicate the microenvironment of the brain with the highest possible fidelity. This technology offers a promising test-bed for studying brain disorders at the cellular and network levels, providing insights into disease mechanisms, drug screening, and, in perspective, the development of personalized therapeutic strategies. In this review, we provide an overview of the BoC models developed over the years to model and understand the onset and progression of some of the most severe neurological disorders in terms of incidence and debilitation (stroke, Parkinson's, Alzheimer's, and epilepsy). We also report some of the cutting-edge therapeutic approaches whose effects were evaluated by means of these technologies. Finally, we discuss potential challenges, and future perspectives of the BoC models.

Respiratory infections (RI) significantly burden society, mainly when there are recurrent respiratory infections (RRI). Thus, there is a need to prevent RI in clinical practice. In this regard, the modulation of the immune system and resolution of the inflammatory cascade could represent an ideal way to prevent RI. Stimunex® gocce, a multicomponent food supplement, contains Sambucus nigra extract, β-glucan, Zinc, and Vitamin D3. This study investigated its ability to prevent RRI in children using a real-world setting: the pediatric primary care. Two hundred and ninety-eight children with RRI were enrolled in the current study. The food supplement was randomly prescribed to 160 children with RRI daily for 4 months (Active group); the remaining 138 children with RRI were treated only with standard therapy for RI (Control group). The number and duration of RI, parental perception of symptom severity and treatment efficacy, use of medications, and school and working absence were evaluated. Children treated with Stimunex® gocce had significantly less RI than the Control group, both concerning upper and lower RI (p˂0.001 and 0.003, respectively) during the follow-up period. Moreover, children in the Active group experienced shorter RI duration during the treatment and follow-up phases (p˂0.001 for both). In addition, parents of treated children perceived less severe symptoms and better treatment efficacy during the first and follow-up phases (p˂0.001 for all). The food supplement was well tolerated and there was no adverse event. The current real-world study demonstrated that Stimunex® gocce supplementation in children with RRI might safely prevent RI episodes and reduce RI duration. These outcomes should be highlighted as obtained during the COVID-19 pandemic era, characterized by a dramatic reduction of RI.

The possibility of distinguishing fibrosing from non-fibrosing lung diseases on high resolution computed tomography (HRCT) is very important in order to be able to establish the appropriate therapy early in the course of the disease and, in some pathologies, to avoid the evolution towards a fibrosing irreversible pattern. For this reason, this article will deal with non-fibrosing pulmonary parenchymal diseases, with an acute or subacute course, which occur on HRCT with a prevalent pattern of diffuse density increase (ground glass opacities and consolidations). Since these alterations, especially ground glass opacities, are often the early sign of the onset of diseases that evolve towards fibrosis, it is important to be able to recognize them and to propose a correct differential diagnosis.

1: ESGE recommends placement of partially or fully covered self-expandable metal stents (SEMSs) for palliation of malignant dysphagia over laser therapy, photodynamic therapy, and esophageal bypass.Strong recommendation, high quality evidence. 2 : ESGE recommends brachytherapy as a valid alternative, alone or in addition to stenting, in esophageal cancer patients with malignant dysphagia and expected longer life expectancy.Strong recommendation, high quality evidence. 3: ESGE recommends esophageal SEMS placement for sealing malignant tracheoesophageal or bronchoesophageal fistulas. Strong recommendation, low quality evidence. 4 : ESGE does not recommend SEMS placement as a bridge to surgery or before preoperative chemoradiotherapy because it is associated with a high incidence of adverse events. Other options such as feeding tube placement are preferable. Strong recommendation, low quality evidence. 5: ESGE recommends against the use of SEMSs as first-line therapy for the management of benign esophageal strictures because of the potential for adverse events, the availability of alternative therapies, and their cost. Strong recommendation, low quality evidence. 6: ESGE suggests consideration of temporary placement of self-expandable stents for refractory benign esophageal strictures. Weak recommendation, moderate quality evidence. 7: ESGE suggests that fully covered SEMSs be preferred over partially covered SEMSs for the treatment of refractory benign esophageal strictures because of their very low risk of embedment and ease of removability. Weak recommendation, low quality evidence. 8: ESGE recommends the stent-in-stent technique to remove partially covered SEMSs that are embedded in the esophageal wall. Strong recommendation, low quality evidence. 9: ESGE recommends that temporary stent placement can be considered for the treatment of leaks, fistulas, and perforations. No specific type of stent can be recommended, and the duration of stenting should be individualized. Strong recommendation, low quality of evidence. 10 : ESGE recommends considering placement of a fully covered large-diameter SEMS for the treatment of esophageal variceal bleeding refractory to medical, endoscopic, and/or radiological therapy, or as initial therapy for patients with massive bleeding. Strong recommendation, moderate quality evidence.
