ABSTRACT
Background: Cancer survivorship results in an increased number of physical and psychosocial health issues. Engaging in physical activity in natural environments is often thought of as restorative. Despite the potential benefits of engaging in physical activity in natural environments there are no sustainable community-based programs for cancer survivors that employ this form of physical activity. This study aims to evaluate the impact of an 8-week trail-walking (TW) program on anxiety in a population of adult cancer survivors. Methods: The TW program consisted of two trail walks per week for 8 weeks led by a hiking guide. Individuals were eligible to participate if they were 19 years or older, were a cancer survivor, were not on active immunotherapy, and had medical clearance from their physician for physical activity. While 12 participants signed up for the program, 9 participants (N = 9, 8 F, 1 M) completed the program. A mixed methodology included preand-post quantitative program surveys and post-program interviews. Questionnaires measured generalized anxiety, sleep disturbances, self-efficacy, self-esteem, psychological well-being and depression as well as pre-and-post hike state anxiety. Data was analysed using paired t-tests. Interviews were transcribed verbatim and an inductive thematic analysis was conducted to consolidate meaning and identify themes using NVivo 11 software. Results: Average attendance was 74% of the 16 hikes. There was no significant reduction in the primary outcome of generalized anxiety (p = .38). There was a significant reduction in perceived stress after 8-weeks (p = .03) and a significant reduction in state anxiety after TW (p < .001). None of the other secondary outcomes were statistically significant (p > .05). Four overarching themes, or benefits, emerged from qualitative data analysis: (a) benefits of program design (b) physical benefits, (c) psychological benefits, and (d) social benefits. Conclusions: These findings demonstrate the utility of a TW program for cancer survivors in order to promote physical, psychological and social health. Feasibility of a TW program would be contingent on access to natural areas for TW and an instructor-led program with other cancer survivors.

BACKGROUND & OBJECTIVES: Vellore is an endemic area for cholera. The relative prevalence of clinical cases of Vibrio cholerae O1 and O139 has been fluctuating. Few studies have examined the susceptibility of local isolates to quinolones. The objective of the present study was to look at quinolone susceptibility and determine MIC of ciprofloxacin to representative clinical isolates of V. cholerae O1 and O139 in Vellore, obtained between 1997 and 1999. METHODS: Antimicrobial susceptibility testing of V. cholerae strains was performed by disc diffusion technique and MIC determination by E test. RESULTS: Five of 30 O1 and all the O139 serogroup isolates were susceptible to nalidixic acid. All isolates of both serogroups were sensitive to norfloxacin. All isolates of both serogroups gave MIC results in the susceptible range to ciprofloxacin; the MICs being lower for V. cholerae O139 (MIC50 = 0.004 microgram/ml and MIC90 = 0.047 microgram/ml) than for O1 serogroup (MIC50 = 0.38 microgram/ml and MIC90 = 0.5 microgram/ml). INTERPRETATION & CONCLUSION: V. cholerae O1 and O139 show differences in quinolone susceptibility, the reason for this is not clear. This could be because of longer exposure of the O1 serogroup to quinolone antimicrobials as compared to the O139 serogroup.
