Physical exercise and social activities play a role of primary importance in the prevention of diseases and in maintaining functional abilities in old age, nevertheless, maintaining a regular habit of exercise is considered a challenge during the aging process. Motivation to start and maintain physical activity is an essential factor. Among older adults, when promoting exercise, it is preferable to focus on means of activities intrinsically pleasurable, rather than on health improvements. From this perspective, our study is aimed to understand if preventative interventions combining physical activity, self-efficacy, and social participation in the context of a natural environment might be of help in increasing the level of physical activity. The sample was composed of 95 subjects, of which 40 were excluded because declared to be already engaged in regular physical activity at baseline. Considering the final sample of 55 subjects with low or no physical activity at baseline, 21 subjects (38.2%) improved the intensity of their physical activity at follow-up. They were younger (52.4% with age >= 70 vs 82.4; p = 0.017), mostly women (85.7% vs 58.8%; p = 0.036), and had a higher balance test score with respect to the others (3.6 ± 0.7 vs 2.8 ± 1.0; p = 0.005). Results should be able to strengthen the concept that having a good level of physical abilities, such as good balance, facilitates the path for greater physical improvements and better quality of life among older adults. Balance issues may be cause of fear of falling and psychological difficulties which may have limited the effects of the programme. [ABSTRACT FROM AUTHOR]

Some livestock farms rely on anaerobic digestion (AD) technology for manure disposal, thus obtaining energy (biogas) and fertilizer (digestate). Mixtures of antibiotics used for animal health often occur in organic waste and their possible synergistic/antagonistic effects on microorganisms involved in AD are still poorly studied. This work focuses on the effects of adding ciprofloxacin, alone (5 mg L−1 ) and in combination with sulfamethoxazole (2.5–5–10 mg L−1 ), on AD efficiency and microbial community structure. The experiment consisted of 90-day cattle manure batch tests and antibiotic removal percentages were assessed. Adding antibiotics always promoted CH4 and H2 production compared to untreated controls; however, CH4 production was lowered with the highest ciprofloxacin (CIP) concentrations. The overall results show antibiotic degradation caused by acidogenic Bacteria, and CH4 was mainly produced through the hydrogenotrophic-pathway by methanogenic Archaea. Shifts in microbial community abundance (DAPI counts) and composition (Illumina-MiSeq and FISH analyses) were observed. [ABSTRACT FROM AUTHOR]
