Abstract
Physical inactivity, a leading risk factor for chronic diseases and premature death, is prevalent worldwide. This study focuses on participant profiles and factors influencing continued participation and physical activity (PA) levels in the "Moving Parks" PA intervention in Bologna, Italy. This intervention offers free group activities in city parks during the summer. A questionnaire was administered to participants in 2022, gathering data on socio-demographic information, chronic diseases, participation in previous iterations, and PA levels. Out of 596 respondents, 85% were women, and the average age was 50. About 56% held a university degree, and 73% exercised regularly in the winter. Continuous participation was linked to older age, higher education, and chronic conditions. Prior participation predicted higher winter PA levels. Notably, the majority of participants were educated, physically active women. While the project continually engages individuals with higher education and chronic conditions, it needs further tailoring to reach less represented populations.

Abstract
An electrochemical study aiming at the evaluation of corrosion parameters using potentiodynamic and potentiostatic techniques ("scratch" and modified ASTM F746) was conducted in 0.9% NaCl on wires from equiatomic Ni-Ti and ternary Ni44Ti51Cu5 superelastic alloys with Ti90Mo10 as a reference material. The results obtained using potentiostatic tests, that simulate better the behavior of material in service conditions than potentiodynamic ones, indicate that both Ni-Ti and Ni-Ti-Cu wires exhibit low corrosion potentials (approximately 50-150 mV versus SCE) inferior to that of Ti-Mo alloy. The latter proved to be immune to localized corrosion attacks up to 800 mV.

Abstract
In this study, potentiodynamic polarization scans, potentiostatic scratch tests, and modified American Society for Testing and Materials F746 tests were carried out in simulated body fluids on commercial orthodontic wires made of different classes of materials and on titanium used as a reference. The stability of passivating film, evaluated by electrochemical techniques that abruptly damage it, e.g., potentiostatic scratch test, increased in the following order: Ni-Ti </= stainless steel < Co-Cr alloy < Ti. Because satisfactory biocompatibilty of implants relies on the presence of a stable and efficient self-repairing passive film, this ranking should be considered in view of in vivo applications. Moreover, scratch tests show that it is not possible to enhance the performance of Ni-Ti samples by modifying surface-passive film by dipping in an HF/HNO(3) mixture. Finally, straining of Ni-Ti wires under superelastic conditions and consequent presence of stress-induced martensite does not substantially modify their localized corrosion resistance.

Abstract
The influence of different surface preparations on titanium biocompatibility and bone integration was evaluated. Commercially grade 2 titanium rods (diameter 2 mm, length: 3 mm), vacuum annealed and hydrofluoric acid etched was selected for its promising surface characteristics to achieve good direct osseointegration. Some rods were surface modified by Anodic Spark Discharge anodization and a thin layer (approximately 5 microm) of amorphous TiO2 containing Ca and P (Ti/AM) was obtained. Some of the Ti/AM specimens underwent a further hydrothermal treatment to produce a thin outermost layer (approximately 1 microm) of hydroxyapatite (Ti/AM/HA). Cytotoxicity tests (direct contact: ISO 10993-5) showed good cytocompatibility for all tested samples. Ti and tissue culture substrate + DMEM control, respectively, were associated with a significant higher proportion of attached cells than Ti/AM and Ti/AM/HA (P < 0.0005), but this was in the normal range of 10-20% of unattached cells for cytocompatible materials. Histomorphometric analysis conducted on samples inserted in the cancellous bone of distal femoral epiphysis of Sprague-Dawley rats gave the following results at 4 and 8 weeks: Affinity index (AI%) data proving the surface osteconductive properties of non-anodized acid etched Ti (AI-4 weeks: 67.1 +/- 17.0%; AI-8 weeks: 74.8 +/- 11.5%). Ti/AM samples showed the lowest values (AI-4 weeks: 45.8 +/- 15.9%; AI-8 weeks: 68.5 +/- 13.6%) while the best performances of the Ti/AM/HA samples (AI-4 weeks: 60.4 +/- 21.8%; AI-8 weeks: 79.5 + 9.37%) indicated that hydroxyapatite allowed a higher bone to implant contact respect to Ti only. Further investigations should be performed in order to better understand the mechanism of observed in vitro behaviour and to achieve information on long-term osseointegration process.

Abstract
The corrosion performances in simulated human body fluids of commercial equiatomic Ni-Ti orthodontic wires having various shape and size and produced by different manufacturers were evaluated; for comparison purposes wires made of stainless steel and of cobalt-based alloy were also examined. Potentiodynamic tests in artificial saliva at 40 degrees C indicated a sufficient pitting resistance for the Ni-Ti wires, similar to that of cobalt-based alloy wire; the stainless steel wire, instead, exhibited low pitting potential. Potentiodynamic tests at 40 degrees C in isotonic saline solution (0.9% NaCl) showed, for Ni-Ti and stainless steel wires, pitting potential values in the range approximately 200-400 mV and approximately 350 mV versus SCE, respectively: consequently, according to literature data (Hoar TP, Mears DC. Proc Roy Soc A 1996;294:486-510), these materials should be considered potentially susceptible to pitting; only the cobalt-based alloy should be immune from pitting. The localized corrosion potentials determined in the same environment by the ASTM F746 test (approximately 0-200 mV and 130 mV versus SCE for Ni-Ti and stainless steel, respectively) pointed out that for these materials an even higher risk of localized corrosion. Slight differences in localized corrosion behaviour among the various Ni-Ti wires were detected.

Abstract
Direct and alternating current electrochemical tests were carried out on Ti6Al4V with different surface finishing and with hydroxyapatite (HA) coatings. Sand-blasting and rough titanium deposits obtained by vacuum plasma spraying (VPS) bring about an increase of passive and corrosion current density (c.d.) with respect to smooth Ti6Al4V, as a consequence of the augmentation of the real surface. The presence of HA deposits obtained by VPS causes an increase of passive and corrosion c.d. of the metallic substrate of about one order of magnitude and this should be taken into account in view of human body applications.

Abstract
The austenitic stainless steels used today for the manufacture of osteosynthesis devices are sensitive to crevice corrosion. In this study the corrosion properties of some duplex stainless steels were evaluated and compared to traditional austenitic stainless steels. According to our results the following ranking was established: 23Cr-4Ni less than AISI 316L less than ASTM F138 less than 22Cr-5Ni-3Mo less than 27Cr-31Ni-3.5Mo less than 25Cr-7Ni-4Mo-N. In particular the results showed that the high-performance 25Cr-7Ni-4Mo-N duplex stainless steel, with high molybdenum and nitrogen contents, can be considered not susceptible to crevice corrosion in the human body. The duplex stainless steels have also better mechanical properties at the same degree of cold working compared with austenitic stainless steels. Hence the 25Cr-7Ni-4Mo-N duplex stainless steel can be considered a convenient substitute of ASTM F138 for orthopedic and osteosynthesis devices.
