Second-hand tobacco smoke in prison: tackling a public health matter through research

This action-research study conducted in a Swiss male post-trial detention centre (120 detainees and 120 staff) explored the attitudes of detainees and staff towards tobacco smoking. Tackling public health matters through research involving stakeholders in prisons implies benefits and risks that need exploration.; The observational study involved multiple strands (quantitative and qualitative components, and air quality measurements). This article presents qualitative data on participants' attitudes and expectations about research in a prison setting.; Semi-structured interviews were used to explore the attitudes of detainees and staff towards smoking before and after a smoke-free regulation change in the prison in 2009. Specific coding and thematic content analysis for research were performed with the support of ATLAS.ti.; In total, 77 interviews were conducted (38 before the regulation change and 39 after the regulation change) with 31 detainees (mean age 35 years, range 22-60 years) and 27 prison staff (mean age 46 years, range 29-65 years). Both detainees and staff expressed satisfaction regarding their involvement in the study, and wished to be informed about the results. They expected concrete changes in smoke-free regulation, and that the research would help to find ways to motivate detainees to quit smoking.; Active involvement of stakeholders promotes public health. Interviewing detainees and prison staff as part of an action-research study aimed at tackling a public health matter is a way of raising awareness and facilitating change in prisons. Research needs to be conducted independently from the prison administrators in order to increase trust and to avoid misunderstandings

Building Inventory and Refurbishment Scenario Database Development for Switzerland

© 2017, Yale University. Material usage and the related embodied environmental impact have grown in significance in the built environment. Therefore, cities and governments need to develop strategies to reduce both the consumption of resources during usage phase as well as the embodied impact of the current building stock. This article proposes a new component-based building inventory database as a basis to develop such strategies using building stock modeling. The developed database clusters the building stock according to building typology (single-family houses, multifamily houses, and office buildings), age, and the main construction systems of the different building components. Based on the component makeup, it lists the necessary material input and waste output for different refurbishment options for each building component. The advantages of the proposed database structure are shown based on two applications for the developed database for Switzerland. The component-based database allows optimization of refurbishment strategies not only from an energetic perspective, but also with respect to materials, both on the input (sourcing of materials) and the output (waste streams) level. The database structure makes it possible to continuously extend the data set by adding new refurbishment options or add data such as component-specific lifetimes, costs, or labor intensities of the refurbishment options. In combination with an aligned economic model, this would give an even more holistic view, impact, and feasibility of different refurbishment scenarios both in environmental and economic terms

Alcohol-selling outlets and mortality in Switzerland--the Swiss National Cohort

AIM To examine the association of alcohol-related mortality and other causes of death with neighbourhood density of alcohol-selling outlets for on-site consumption. DESIGN, SETTING AND PARTICIPANTS Longitudinal study of the adult Swiss population (n = 4 376 873) based on census records linked to mortality data from 2001 to 2008. MEASUREMENTS Sex-specific hazard ratios (HR) for death and 95% confidence intervals (95%CI) were calculated using Cox models adjusting for age, educational level, occupational attainment, marital status and other potential confounders. The density of alcohol-selling outlets within 1000 m of the residence was calculated using geocodes of outlets and residences. FINDINGS Compared with >17 outlets within 1000 m the HR for alcohol-related mortality in men was 0.95 (95%CI: 0.89-1.02) for 8-17 outlets, 0.84 (95%CI: 0.77-0.90) for 3-7 outlets, 0.76 (95%CI: 0.68-0.83) for 1-2 outlets and 0.60 (95%CI: 0.51-0.72) for 0 outlets. The gradient in women was somewhat steeper, with a HR comparing 0 with >17 outlets of 0.39 (95%CI: 0.26-0.60). Mortality from mental and behavioural causes and lung cancer were also associated with density of alcohol-selling outlets: HRs comparing 0 outlets with >17 outlets were 0.64 (95%CI: 0.52-0.79) and 0.79 (95%CI: 0.72-0.88), respectively, in men and 0.46 (95%CI: 0.27-0.78) and 0.63 (95%CI: 0.52-0.77), respectively, in women. There were weak associations in the same direction with all-cause mortality in men but not in women. CONCLUSIONS In Switzerland, alcohol-related mortality is associated with the density of outlets around the place of residence. Community-level interventions to reduce alcohol outlet density may usefully complement existing interventions

Efficacy, tolerability and risk factors for virological failure of darunavir-based therapy for treatment-experienced HIV-infected patients: the Swiss HIV Cohort Study

OBJECTIVES: Darunavir was designed for activity against HIV resistant to other protease inhibitors (PIs). We assessed the efficacy, tolerability and risk factors for virological failure of darunavir for treatment-experienced patients seen in clinical practice. METHODS: We included all patients in the Swiss HIV Cohort Study starting darunavir after recording a viral load above 1000 HIV-1 RNA copies/mL given prior exposure to both PIs and nonnucleoside reverse transcriptase inhibitors. We followed these patients for up to 72 weeks, assessed virological failure using different loss of virological response algorithms and evaluated risk factors for virological failure using a Bayesian method to fit discrete Cox proportional hazard models. RESULTS: Among 130 treatment-experienced patients starting darunavir, the median age was 47 years, the median duration of HIV infection was 16 years, and 82% received mono or dual antiretroviral therapy before starting highly active antiretroviral therapy. During a median patient follow-up period of 45 weeks, 17% of patients stopped taking darunavir after a median exposure of 20 weeks. In patients followed beyond 48 weeks, the rate of virological failure at 48 weeks was at most 20%. Virological failure was more likely where patients had previously failed on both amprenavir and saquinavir and as the number of previously failed PI regimens increased. CONCLUSIONS: As a component of therapy for treatment-experienced patients, darunavir can achieve a similar efficacy and tolerability in clinical practice to that seen in clinical trials. Clinicians should consider whether a patient has failed on both amprenavir and saquinavir and the number of failed PI regimens before prescribing darunavir
