Prescription appropriateness of anti-diabetes drugs in elderly patients hospitalized in a clinical setting: evidence from the REPOSI Register

Diabetes is an increasing global health burden with the highest prevalence (24.0%) observed in elderly people. Older diabetic adults have a greater risk of hospitalization and several geriatric syndromes than older nondiabetic adults. For these conditions, special care is required in prescribing therapies including anti- diabetes drugs. Aim of this study was to evaluate the appropriateness and the adherence to safety recommendations in the prescriptions of glucose-lowering drugs in hospitalized elderly patients with diabetes. Data for this cross-sectional study were obtained from the REgistro POliterapie-Società Italiana Medicina Interna (REPOSI) that collected clinical information on patients aged ≥ 65 years acutely admitted to Italian internal medicine and geriatric non-intensive care units (ICU) from 2010 up to 2019. Prescription appropriateness was assessed according to the 2019 AGS Beers Criteria and anti-diabetes drug data sheets.Among 5349 patients, 1624 (30.3%) had diagnosis of type 2 diabetes. At admission, 37.7% of diabetic patients received treatment with metformin, 37.3% insulin therapy, 16.4% sulfonylureas, and 11.4% glinides. Surprisingly, only 3.1% of diabetic patients were treated with new classes of anti- diabetes drugs. According to prescription criteria, at admission 15.4% of patients treated with metformin and 2.6% with sulfonylureas received inappropriately these treatments. At discharge, the inappropriateness of metformin therapy decreased (10.2%, P < 0.0001). According to Beers criteria, the inappropriate prescriptions of sulfonylureas raised to 29% both at admission and at discharge. This study shows a poor adherence to current guidelines on diabetes management in hospitalized elderly people with a high prevalence of inappropriate use of sulfonylureas according to the Beers criteria

[Computerized tomography and magnetic resonance in radical and reconstructive surgery using pedunculated and revascularized flaps in advanced-stage tumors of the head and neck. Analysis of recurrences. II].

January, 1992, to October, 1995, sixty-four patients with advanced head and neck carcinoma were submitted to reconstructive surgery using pedunculated myocutaneous or revascularized flaps and then to CT and MRI. Myocutaneous flaps were used in 26 cases--12 tubular and 14 linear flaps--and revascularized flaps in 38--14 latissimus dorsi flaps, 12 temporal flaps, 7 jejunal flaps and 5 radial flaps. Twenty-six of 64 cases (41%) relapsed: MRI correctly depicted the recurrence in 24 cases and CT in 19, with 2 false positives and 2 false negatives at MRI and 6 false positives and 7 false negatives at CT. The sensitivity, specificity, accuracy, positive and negative predictive value of CT were 84%, 78%, 73%, 76% and 82%, respectively, while the corresponding MR rates were 95%, 94%, 92%, 92% and 95%. MRI was more accurate than CT in demonstrating postoperative and postirradiation changes (92% for MRI versus 73% for CT) thanks to its higher sensitivity in depicting tumor tissue on T2-weighted and post-Gd-DTPA images. CT is very useful in the early postoperative period, to follow-up poorly collaborative patients, because its acquisition time is short; MRI should be performed when CT findings are questionable and the revascularized flap is used to repair a large defect at the skull base

[Anatomic changes after radical surgery and reconstruction with pedunculated or revascularized flaps in advanced head and neck tumors: computerized tomography and magnetic resonance findings].

January, 1992, to October, 1995, sixty-four patients with advanced head and neck cancer underwent head and neck reconstructive surgery using myocutaneous or revascularized flaps; in the same period, all patients were consecutively examined with CT and MRI. Myocutaneous flaps wer used in 26 patients: 12 flaps were tubular and 14 linear. Revascularized flaps were used in 38 patients: to repair a large defect in 26 patients (14 latissimus dorsi flaps and 12 temporal muscle flaps) and to repair an oral damage in 12 patients (5 revascularized radial and 7 jejunal flaps). CT and MR images of myocutaneous flaps showed the flaps as fatty areas, repairing large surgical defects, hypodense at CT and hyperintense at MRI, with no post-contrast enhancement. The postoperative scar around the flap exhibited soft-tissue density with slight post-contrast enhancement at CT and slightly hypodense on T2-weighted MR images. Post-contrast CT and MRI showed slight scar enhancement with no signal changes in the fatty component. The appearance of revascularized flaps at CT and MRI depends on the characteristics of the structure used to repair the surgical defect: jejunal and radial flaps appeared as mostly fatty thickened layers with both imaging methods. Temporal and latissimus dorsi flaps are made basically of muscular tissue, fatty tissue and occasionally skin (used to repair a mucosal defect): consequently, CT showed a structure with mostly parenchymal density in all cases and MRI depicted intermediate signal intensity. MRI was useful to detect 12 revascularized jejunal or radial flaps thanks to its higher contrast resolution and multiplanar capabilities showing even such thin structures as these flaps. Moreover, MRI permitted to study skull base reconstruction with revascularized (latissimus dorsi) flaps in 5 of our patients

Digital Modernism Heritage Lexicon

The book investigates the theme of Modernism (1920-1960 and its epigones) as an integral part of tangible and intangible cultural heritage which contains the result of a whole range of disciplines whose aim is to identify, document and preserve the memory of the past and the value of the future. Including several chapters, it contains research results relating to cultural heritage, more specifically Modernism, and current digital technologies. This makes it possible to record and evaluate the changes that both undergo: the first one, from a material point of view, the second one from the research point of view, which integrates the traditional approach with an innovative one. The purpose of the publication is to show the most recent studies on the modernist lexicon 100 years after its birth, moving through different fields of cultural heritage: from different forms of art to architecture, from design to engineering, from literature to history, representation and restoration. The book appeals to scholars and professionals who are involved in the process of understanding, reading and comprehension the transformation that the places have undergone within the period under examination. It will certainly foster the international exchange of knowledge that characterized Modernism

Statins, ACE/ARBs drug use, and risk of pneumonia in hospitalized older patients: a retrospective cohort study

: The aims of this study is to evaluate the association between angiotensin-converting enzyme inhibitor (ACE-I), angiotensin II receptor blocker (ARBs) and/or statin use with the risk of pneumonia, as well as and with in-hospital and short-term outpatient mortality in hospitalized older patients with pneumonia. Patients aged 65 years or older hospitalized in internal medicine and/or geriatric wards throughout Italy and enrolled in the REPOSI (REgistro Politerapuie SIMI-Società Italiana di Medicina Interna) register from 2010 to 2019 were screened to assess the diagnosis of pneumonia and classified on whether or not they were prescribed with at least one drug among ACE-I, ARBs, and/or statins. Further study outcomes were mortality during hospital stay and at 3 months after hospital discharge. Among 5717 cases included (of whom 18.0% with pneumonia), 2915 (51.0%) were prescribed at least one drug among ACE-I, ARBs, and statins. An inverse association was found between treatment with ACE-I or ARBs and pneumonia (OR = 0.79, 95% CI 0.65-0.95). A higher effect was found among patients treated with ACE-I or ARBs in combination with statins (OR = 0.67, 95% CI 0.52-0.85). This study confirmed in the real-world setting that these largely used medications may reduce the risk of pneumonia in older people, who chronically take them for cardiovascular conditions
