Background The rising incidence of chronic diseases among the population, further exacerbated by the phenomenon of aging, is a primary concern and a serious challenge for the healthcare systems worldwide. Among the wide realm of health digital technologies, the rise of Digital Therapeutics (DTx), which are medical devices able to deliver evidence-based treatments to manage and treat diseases, opens new opportunities. However, their diffusion and usage are still fragmented among countries. As the diffusion results from the adoption of technology from a social system and individual acceptance, this study aims to design and test a theoretical model that investigates the intention to use DTx, with a particular focus on the treatment of obesity, as a widespread and burdensome chronic condition. Methods This research is built on 336 answers coming from a survey to test the proposed model, which consists of a combination of organizational mechanisms, derived from Institutional Theory, and rational factors, derived from the Technology Acceptance Model (TAM). The survey has been delivered to patients and former patients of Istituto Auxologico Italiano, a hospital with several locations in northern Italy, recognized as a center of excellence for the treatment of obesity. Results The analyses of the answers, performed through the Structural Equation Modelling (SEM) technique, confirmed the influence of the Perceived Usefulness on Intention To Use, and of the Perceived Ease Of Use on the Perceived Usefulness, confirming the validity of the assumptions derived from the TAM. On the other hand, institutional factors were introduced as antecedents of the Perceived Usefulness, and the Perceived Ease Of Use. Results show that the Regulative Pillar influences both the TAM constructs, the Normative Pillar (peer influence) has a positive effect only on the Perceived Usefulness, and finally, the Cultural Pillar impacts the Perceived Ease Of Use. Conclusion This study allows filling the knowledge gap regarding the usage of the Institutional as a means to predict individuals’ intentions. Moreover, managerial contributions are available as the results have been operationalized into practical advice to managers and healthcare professionals to foster the adoption, and thus the diffusion, of Digital Therapeutics.

Background and aims The most recent guidelines suggest treating patients whose FRAX 10-year fracture risk scores are ≥ 20%. However, this method of evaluation does not take into account parameters that are nonetheless relevant to the therapeutic choice. Our aim was to compare the therapeutic choices for treatment based on a wider assessment (real-world practice) with those based on FRAX scores, taking 20% as the cut-off score. Methods We obtained the medical history, bone mineral density (BMD) values, and the presence of major fragility fractures in a sample of 856 postmenopausal women. The 10-year FRAX risk of major osteoporotic fracture was calculated, and patients were grouped into risk classes (“FRAX < 20%” = low, “FRAX ≥ 20%” = high); we then compared the treated and untreated patients in each class. After an average interval of 2.5 years, changes in lumbar and femoral BMD and appearances of new fragility fractures were recorded. Results 83% of high-risk patients and 57% of low-risk patients were treated. The therapeutic decision was based mainly on densitometric values and the presence of vertebral fractures. At the 2.5 year follow-up, lumbar spine and femur BMD had decreased in the untreated group; 9.9% of the treated patients developed new vertebral fragility fractures, compared with 5.3% of the untreated patients. Discussion and conclusions Our wider assessment designated as at high fracture risk a group of patients who had not been identified by the FRAX assessment. FRAX could underestimate the risk of fracture in older people, for which the therapeutic choice should consider a broader approach, also based on individual patient’s needs.

Key summary points Aim To comparatively assess the clinical profiles of older patients treated with trazodone or other antidepressants in a large dataset from the GeroCovid Observational multiscope and multisetting study. Findings 10.8% out of 3396 persons included used trazodone and the 8.5% other antidepressants; the use of trazodone was highly prevalent in functionally dependent and comorbid older adults admitted to long-term care facilities or living at home. Conditions associated with trazodone use included depression, dementia and behavioral and psychological symptoms of dementia. Message The present data suggest an off-label use of trazodone as a possible therapeutic option in the challenging field of behavioral and psychological disturbances in older adults with dementia.

In order to plan treatment or follow-up of pancreatic cystic lesions, is crucial to distinguish benign from malignant cystic tumors with reliable, non-invasive methods. Despite evaluation with several preoperative investigations, a correct pathologic diagnosis rate does not exceed 68%. 2-[18F]-fluoro-2-deoxy-D-glucose positron emission tomography (18F-FDG PET-CT) has been found to be a highly sensitive and specific non-invasive procedure to detect malignancy in cystic tumors of the pancreas (CTP). The introduction of hybrid PET/CT scans allowed a more accurate localization of the foci of hypermetabolism. We reviewed 14 series (645 patients) with a CTP who underwent 18F-FDG PET-CT from 2001; four of these studies came from our group of investigators (226 patients). In the last studies, sensitivity in detecting malignancy ranged from 83 to 100% and specificity from 78 to 100%. 18F-FDG PET-CT for a long time was used only when conventional imaging was insufficient to rule out a cancer. In our experience, 18F-FDG PET-CT was found to be reliable to detect "cancer in situ" when no other investigations could detect it, so we stress the use of 18F-FDG PET-CT in the first assessment, as alternative to EUS with FNA, to exclude malignancy. We are lacking data about the use of 18F-FDG PET-CT and timing in the follow-up of patients (un)-operated. We suggest a regular use in the follow up of patients with intraductal papillary mucinous neoplasms (IPMN), due to their multifocality and to the high rate of extra-pancreatic cancers.
