Substance use disorder treatment programs in Switzerland and the USA: Program characteristics and 1-year outcomes

AIM: This study compared matched samples of substance use disorder (SUD) patients in Swiss and United States (US) residential treatment programs and examined the relationship of program characteristics to patients' substance use and psychosocial functioning at a 1-year follow-up. DESIGN AND SETTING: The study used a prospective, naturalistic design and a sample of 10 public programs in the German-speaking part of Switzerland and 15 US public treatment programs. PARTICIPANTS: A total of 358 male patients in Swiss programs were matched on age, marital status and education with 358 male patients in US programs. A total of 160 Swiss and 329 US patient care staff members also participated. MEASUREMENT: Patients completed comparable inventories at admission, discharge and 1-year follow-up to assess their substance use and psychological functioning and receipt of continuing care. Staff members reported on program characteristics and their beliefs about substance use. FINDINGS: Compared to Swiss patients, US patients had more severe substance use and psychological problems at intake and although they did not differ on abstinence and remission at follow-up, had somewhat poorer outcomes in other areas of functioning. Swiss programs were longer and included more individual treatment sessions; US programs included more group sessions and were more oriented toward a disease model of treatment. Overall, length of program, treatment intensity and 12-step orientation were associated with better 1-year outcomes for patients in both Swiss and US programs. CONCLUSIONS: The sample of Swiss and US programs studied here differed in patient and treatment characteristics; however, in general, there were comparable associations between program characteristics and patients' 1-year outcomes. These findings suggest that associations between treatment processes and patients' outcomes may generalize from one cultural context to another.

An analysis of the Galveston Hurricane using the 20CR data set

The Twentieth Century Reanalysis (20CR) is an atmospheric dataset consisting of 56 ensemble members, which covers the entire globe and reaches back to 1871. To assess the suitability of this dataset for studying past extremes, we analysed a prominent extreme event, namely the Galveston Hurricane, which made landfall in September 1900 in Texas, USA. The ensemble mean of 20CR shows a track of the pressure minimum with a small standard deviation among the 56 ensemble members in the area of the Gulf of Mexico. However, there are systematic differences between the assimilated “Best Track” from the International Best Track Archive for Climate Stewardship (IBTrACS) and the ensemble mean track in 20CR. East of the Strait of Florida, the tracks derived from 20CR are located systematically northeast of the assimilated track while in the Gulf of Mexico, the 20CR tracks are systematically shifted to the southwest compared to the IBTrACS position. The hurricane can also be observed in the wind field, which shows a cyclonic rotation and a relatively calm zone in the centre of the hurricane. The 20CR data reproduce the pressure gradient and cyclonic wind field. Regarding the amplitude of the wind speeds, the ensemble mean values from 20CR are significantly lower than the wind speeds known from measurements.

Swiss Army Survey in Switzerland to determine the prevalence of Francisella tularensis, members of the Ehrlichia phagocytophila genogroup, Borrelia burgdorferi sensu lato, and tick-borne encephalitis virus in ticks

A total of 6071 Ixodes ricinus ticks were collected on Swiss Army training grounds in five regions of Switzerland. The aim of the survey was to assess the prevalence of ticks infected with the human pathogens Francisella tularensis, members of the Ehrlichia phagocytophila genogroup, Borrelia burgdorferi sensu lato, and the European tick-borne encephalitis virus. TaqMan PCR (PE Biosystems, USA) and TaqMan RT-PCR (PE Biosystems) analyses were performed on DNA and RNA extracted from pools of ten ticks grouped by gender. Here, for the first time, it is shown that ticks may harbor Francisella tularensis in Switzerland, at a rate of 0.12%. Furthermore, 26.54% of the ticks investigated harbored Borrelia burgdorferi sensu lato, 1.18% harbored members of the Ehrlichia phagocytophila genogroup, and 0.32% harbored the European tick-borne encephalitis virus. A new instrumentation was applied in this study to carry out and analyze more than 2300 PCR reactions in only 5 days. Furthermore, the results reveal that people working in outdoor areas, including army personnel on certain training grounds contaminated with ticks containing tick-borne pathogens, are at risk for different tick-borne diseases.

Occurrence of spontaneous tumours of the renal proximal tubules in oscars Astronotus ocellatus

This report describes the occurrence of renal papillary cystic adenomas and adenocarcinomas in oscars Astronotus ocellatus Cuvier, 1829. Samples from 5 oscars with abdominal swelling were collected between 1996 and 2004 and compared to a published case from the USA. Macroscopically, all cases revealed a large, well-demarcated, greyish-brown nodular mass in a retroperitoneal position within the body cavity, and originating from the posterior kidney. Histologically, these neoplasms were composed of epithelial cells, which were arranged in papillary cystic tubular structures and partly covered by cilia. In this study, microscopic and ultrastructural examination confirmed that the origin of the neoplasm was the proximal tubules of the kidney.

Comparing the validity and output of the GT1M and GT3X accelerometer in 5- to 9-year-old children

The purpose of this study was to compare the validity and output of the biaxial ActiGraph GT1M and the triaxial GT3X (ActiGraph, LLC, Pensacola, FL, USA)accelerometer in 5- to 9-year-old children. Thirty-two children wore the two monitors while their energy expenditure was measured with indirect calorimetry. They performed four locomotor and four play activities in an exercise laboratory and were further measured during 12 minutes of a sports lesson. Validity evidence in relation to indirect calorimetry was examined with linear regression equations applied to the laboratory data. During the sports lessons predicted energy expenditure according to the regression equations was compared to measured energy expenditure with the Wilcoxon-signed rank test and the Spearman correlation. To compare the output, agreement between counts of the two monitors during the laboratory activities was assessed with Bland-Altman plots. The evidence of validity was similar for both monitors. Agreement between the output of the two monitors was good for vertical counts (mean bias = −14 ± 22 counts) but not for horizontal counts (−17 ± 32 counts). The current results indicate that the two accelerometer models are able to estimate energy expenditure of a range of physical activities equally well in young children. However, they show output differences for movement in the horizontal direction.

Through the European Looking Glass: Citizenship Tests in the USA, Australia, and Canada

Discussing new or recently reformed citizenship tests in the USA, Australia, and Canada, this article asks whether they amount to a restrictive turn of new world citizenship, similar to recent developments in Europe. I argue that elements of a restrictive turn are noticeable in Australia and Canada, but only at the level of political rhetoric, not of law and policy, which remain liberal and inclusive. Much like in Europe, the restrictive turn is tantamount to Muslims and Islam moving to the center of the integration debate.

Adherence as a Predictor of the Development of Class-Specific Resistance Mutations: The Swiss HIV Cohort Study

Background Non-adherence is one of the strongest predictors of therapeutic failure in HIV-positive patients. Virologic failure with subsequent emergence of resistance reduces future treatment options and long-term clinical success. Methods Prospective observational cohort study including patients starting new class of antiretroviral therapy (ART) between 2003 and 2010. Participants were naïve to ART class and completed ≥1 adherence questionnaire prior to resistance testing. Outcomes were development of any IAS-USA, class-specific, or M184V mutations. Associations between adherence and resistance were estimated using logistic regression models stratified by ART class. Results Of 314 included individuals, 162 started NNRTI and 152 a PI/r regimen. Adherence was similar between groups with 85% reporting adherence ≥95%. Number of new mutations increased with increasing non-adherence. In NNRTI group, multivariable models indicated a significant linear association in odds of developing IAS-USA (odds ratio (OR) 1.66, 95% confidence interval (CI): 1.04-2.67) or class-specific (OR 1.65, 95% CI: 1.00-2.70) mutations. Levels of drug resistance were considerably lower in PI/r group and adherence was only significantly associated with M184V mutations (OR 8.38, 95% CI: 1.26-55.70). Adherence was significantly associated with HIV RNA in PI/r but not NNRTI regimens. Conclusion Therapies containing PI/r appear more forgiving to incomplete adherence compared with NNRTI regimens, which allow higher levels of resistance, even with adherence above 95%. However, in failing PI/r regimens good adherence may prevent accumulation of further resistance mutations and therefore help to preserve future drug options. In contrast, adherence levels have little impact on NNRTI treatments once the first mutations have emerged.

Change of the condyle-position in maximum intercuspidation during digital, clinical occlusal analysis

Digital analysis of the occlusal contacts can be performed with the T-scan device (T Scan III, TekScan, Boston, USA). However, the thickness of the interocclusal T-scan sheet (100 μm) may lead to a displacement of the mandible. Thus, the aim of this study was to investigate the impact of the T-scan sheet on the position of the mandibular condyles in maximum intercuspidation. Twenty dentate subjects with healthy jaw function were enrolled in the study. An ultrasonic axiography device was used to measure the position of the condyles. Ten 3D condyle positions in maximum intercuspidation of the teeth were recorded: first the reference position without the sheet, then 3 times without the sheet, 3 times with the sheet, and finally again 3 times without the sheet. There was a statistically significant difference (Wilcoxon matched pairs test) between the condyle positions with and without the interocclusally positioned T-scan sheet (P < 0.0005). The T-scan device lead to a displacement of the condyles of about 1 mm mainly in ventral direction (P = 0.005). Thus, occlusal analysis is not performed in physiological, maximum intercuspidation. This has to be considered when interpreting the measured contact points.
