A FORTRESS BETWEEN ARTIFICE AND NATURE: THE LASER SCANNING SURVEY OF THE CASTLE OF PESCOPAGANO AS AN INSTRUMENT OF KNOWLEDGE, CONSERVATION AND ENHANCEMENT
Abstract. The castle of Pescopagano, a small village located on the border between Basilicata and Campania, is a complex of great historical and landscape value, for the inseparable combination that binds its stones to the rock where it stands. Founded perhaps in the Byzantine times, but certainly renovated and built in its current forms between the 11th and 12th century, the castle had considerable military importance under Frederick II of Swabia. Seriously damaged by the earthquake of 1694, the fortress underwent a partial reconstruction, but ended up suffering further collapses caused by the Irpinia earthquake of 1980, such as to motivate the first interventions of securing and, above all, the application of the listing process. Today the castle is still largely in ruins and is only partially accessible thanks to a limited intervention on the paths. The present research aims at deepening the knowledge of the state of conservation, the damage mechanisms and the previous restoration interventions of the castle, in order to define possible strategies for its restoration and enhancement. The analysis work uses the most advanced laser scanning and drone detection systems, in order to document, as accurately as possible, the complex patrimonial system of the castle. Thanks to the combined use of these techniques, the objective is also to define methods that can be replicated in other contexts where the relationship between geomorphology and construction is so relevant that it jeopardizes the use of any other traditional survey system
High serum osteopontin levels are associated with prevalent fractures and worse lipid profile in post-menopausal women with type 2 diabetes
Purpose: Patients with type 2 diabetes (T2DM) have increased fracture risk. Osteopontin (OPN) is a protein involved in bone remodeling and inflammation. The aim of this study was to evaluate the association of OPN with fracture prevalence and with metabolic parameters in post-menopausal women with T2DM. Methods: Sixty-four post-menopausal women with T2DM (age 67.0 ± 7.8 years, diabetes duration 8.9 ± 6.7 years), enrolled in a previous study, were followed up (3.6 ± 0.9 years). Previous fragility fractures were recorded. The FRAX score (without BMD) was calculated and biochemical parameters (plasma glucose, HbA1c, lipid profile and renal function) were assessed. Serum 25OH-vitamin D, calcium, PTH and OPN were evaluated at baseline. The association between OPN and fracture prevalence at baseline was evaluated by a logistic model. Results: OPN levels were higher in patients with previous fractures (n.25) than in patients without previous fractures at baseline (n.39) (p = 0.006). The odds of having fractures at baseline increased by 6.7 (1.9–31.4, 95% CI, p = 0.007) for each increase of 1 ng/ml in OPN levels, after adjustment for vitamin D and HbA1c levels. Fracture incidence was 4.7%. Higher OPN associated with a decrease in HDL-cholesterol (p = 0.048), after adjustment for age, basal HDL-cholesterol, basal and follow-up HbA1c and follow-up duration. 25OH-vitamin D associated with an increase in FRAX-estimated probability of hip fracture at follow-up (p = 0.029), after adjustment for age, 25OH-vitamin D and time. Conclusions: In post-menopausal women with T2DM, OPN might be a useful marker of fracture and worse lipid profile
Prognostic and predictive value of circulating tumor cells and CXCR4 expression as biomarkers for a CXCR4 peptide antagonist in combination with carboplatin-etoposide in small cell lung cancer: exploratory analysis of a phase II study.
Background Circulating tumor cells (CTCs) and chemokine (C-X-C motif) receptor 4 (CXCR4) expression in CTCs and tumor tissue were evaluated as prognostic or predictive markers of CXCR4 peptide antagonist LY2510924 plus carboplatin-etoposide (CE) versus CE in extensive-stage disease small cell lung cancer (ED-SCLC). Methods This exploratory analysis of a phase II study evaluated CXCR4 expression in baseline tumor tissue and peripheral blood CTCs and in post-treatment CTCs. Optimum cutoff values were determined for CTC counts and CXCR4 expression in tumors and CTCs as predictors of survival outcome. Kaplan-Meier estimates and hazard ratios were used to determine biomarker prognostic and predictive values. Results There was weak positive correlation at baseline between CXCR4 expression in tumor tissue and CTCs. Optimum cutoff values were H-score ≥ 210 for CXCR4+ tumor, ≥7% CTCs with CXCR4 expression (CXCR4+ CTCs), and ≥6 CTCs/7.5 mL blood. Baseline H-score for CXCR4+ tumor was not prognostic of progression-free survival (PFS) or overall survival (OS). Baseline CXCR4+ CTCs ≥7% was prognostic of shorter PFS. CTCs ≥6 at baseline and cycle 2, day 1 were prognostic of shorter PFS and OS. None of the biomarkers at their respective optimum cutoffs was predictive of treatment response of LY2510924 plus CE versus CE. Conclusions In patients with ED-SCLC, baseline CXCR4 expression in tumor tissue was not prognostic of survival or predictive of LY2510924 treatment response. Baseline CXCR4+ CTCs ≥7% was prognostic of shorter PFS. CTC count ≥6 at baseline and after 1 cycle of treatment were prognostic of shorter PFS and OS

Optimal settings for childbirth.
Many studies highlight how health is influenced by the settings in which people live, work, and receive health care. In particular, the setting in which childbirth takes place is highly influential. The physiological processes of women's labor and birth are enhanced in optimal ("salutogenic," or health promoting) environments. Settings can also make a difference in the way maternity staff practice. This paper focuses on how positive examples of Italian birth places incorporate principles of healthy settings. The "Margherita" Birth Center in Florence and the Maternity Home "Il Nido" in Bologna were purposively selected as cases where the physical-environmental setting seemed to reflect an embedded model of care that promotes health in the context of childbirth. Narrative accounts of the project design were collected from lead professional and direct inspections performed to elicit the key salutogenic components of the physical layout. Comparisons between cases with a standard hospital labor ward layout were performed. Cross-case similarities emerged. The physical characteristics mostly related to optimal settings were a result of collaborative design decisions with stakeholders and users, and the resulting local intention to maximize safe physiological birth, psychosocial wellbeing, facilitate movement and relaxation, prioritize space for privacy, intimacy, and favor human contact and relationships. The key elements identified in this paper have the potential to inform further investigations for the design or renovation of all birth places (including hospitals) in order to optimize the salutogenic component of any setting in any country
Differential Binary Encoding Method for Calibrating Image Sensors Based on IOFBs
Image transmission using incoherent optical fiber bundles (IOFBs) requires prior calibration to obtain the spatial in-out fiber correspondence necessary to reconstruct the image captured by the pseudo-sensor. This information is recorded in a Look-Up Table called the Reconstruction Table (RT), used later for reordering the fiber positions and reconstructing the original image. This paper presents a very fast method based on image-scanning using spaces encoded by a weighted binary code to obtain the in-out correspondence. The results demonstrate that this technique yields a remarkable reduction in processing time and the image reconstruction quality is very good compared to previous techniques based on spot or line scanning, for example
