s. When applying these tax models to current sales prices of these products we found that no public health goal, such as protecting youth and reducing tobacco-associated morbidity and mortality can be achieved. The price of tobacco products is too low to achieve any price differentiation that reflects the different risks associated with ENDS and tobacco products. In order to achieve any public health goal with one of these tax models, prices for tobacco products need to be increased substantially.
For patients with difficult venous access after long-term intravenous drug use, rapid point-of-care hepatitis C virus (HCV) RNA quantification in capillary whole blood with the Xpert® HCV Viral Load Fingerstick (VL FS) test (60 minutes) is a convenient and reliable method for diagnosing chronic HCV infection, monitoring treatment and detecting reinfection. However, an expensive GeneXpert® system must be available on site. In decentralised settings with a low case-load, dried blood spot (DBS) testing might be an alternative.

Between December 2019 and January 2021, patients with an indication for HCV RNA quantification and informed consent provided 100 µl capillary whole blood each for on-site Xpert® HCV VL FS testing (reference) and DBS testing in the laboratory. For the latter, 100 µl blood, collected with an EDTA Minivette®, were transferred to a Whatman® 903 filter card. After drying for at least 1 hour, the DBS sample was packed into a sealable plastic bag with desiccant and sent to the central laboratpe 1a and 3a, 2 unknown; HCV RNA range 2.74-6.66 log IU/ml) correlated well (R2 = 0.981). On average, uncorrected DBS test results were 1.30 ± 0.14 log IU/ml lower than Xpert® HCV VL FS test results (~42 μl instead of the expected 1000 μl plasma used). Storage of DBS samples at room temperature for 7 days before freezing reduced HCV RNA by 0.29 ± 0.12 log IU/ml.

HCV RNA can reliably be quantified with the Xpert® HCV VL test in capillary dried blood spot samples. Thus, access to capillary HCV RNA quantification for diagnosing chronic HCV infection, monitoring treatment and detecting reinfection can be extended to decentralised settings with a low case load.

Spontaneous coronary artery dissection (SCAD) is an increasingly diagnosed cause of acute myocardial infarction. However, there is still a limited number of larger cohorts with long-term follow-up. We report on the largest Swiss single-centre cohort to date, with follow-up of up to 22 years.

We prospectively collected SCAD cases from June 1998 until December 2020. A strategy of systematic follow-up angiography was applied. Information on long-term follow-up was collected up to the end of 2020. Major cardiovascular events (MACE) were defined as all-cause death, non-fatal MI, and non-fatal cardiac arrest.

We identified 105 SCAD patients (mean age 53 ± 11 years, 98 female, 5 peripartum). Presentation was myocardial infarction in all patients. In 102 patients, there was one contiguous dissection. Three patients had two (n = 2) or three (n = 1) non-contiguous dissections. In the majority of patients (n = 97), the primary treatment approach was conservative (dual antiplatelet therapy for 12 months in 90% of pyocardial infarction with persistent, multisite SCAD 10 days after the index event (n = 1). There were 10 late MACE, including myocardial infarction and recurrent SCAD (different vessel/lesion) a median of 7.6 years (IQR 3.9-9.6) after the index event in eight patients and death with unclear cause in two patients.

This SCAD series highlights its highly variable clinical course during the acute phase and in the long term. Although most SCAD patients can be treated conservatively with subsequent healing of the dissection and good clinical outcome, there are also patients with dramatic acute presentation or MACE several years after the initial presentation.

Improvement of paediatric healthcare is hampered by inefficient processes for generating new evidence. Clinical research often requires extra encounters with patients, is costly, takes place in an artificial situation with a biased selection of patients, and entails long delays until new evidence is implemented into health care. Electronic health records (EHR) contain detailed information on real patients and cover the entirety of patients. However, the use of EHR for research is limited because they are not standardised between hospitals. This leads to disproportionate amounts of work for extracting data of interest and frequently data are incomplete and of poor quality.

SwissPedData aims to lay the foundation for a paediatric learning health system in Switzerland by facilitating EHR-based research. In this project, we aimed to assess the way routine clinical data are currently recorded in large paediatric clinics in Switzerland and to develop a national EHR-based set of common data elements (CDEs) that tric learning health system in Switzerland that enables fast and efficient answers to urgent clinical questions by facilitating high-quality nationwide retrospective and prospective observational studies and recruitment of patients for nested prospective studies and clinical trials.From July 2020 through June 2021, a total of 539 members of the active (n=469) and reserve (n=70) components had at least 1 medical encounter with a primary diagnosis of cold injury. The crude overall incidence rate of cold injury for all active component service members in 2020–2021 (35.4 per 100,000 person-years [p-yrs]) was higher than the rate for the 2019–2020 cold season (27.5 per 100,000 p-yrs). In 2020–2021, frostbite was the most common type of cold injury among active component service members in all 4 services. Among active component members during the 2016–2021 cold seasons, overall rates of cold injuries were generally highest among male service members, non-Hispanic Black service members, the youngest (less than 20 years old), and those who were enlisted. The number of cold injuries associated with overseas deployments during the 2020–2021 cold season (n=10) was the lowest count during the 5-year surveillance period. Immersion foot accounted for half (n=5) of the cold weather injuries diagnosed and treated in service members deployed outside of the U.S. during the 2020–2021 cold season.
Two venomous snakes, the asp viper (Vipera aspis) and the common adder (Vipera berus) are native to Switzerland. Bites by both vipers cause mainly local effects, but systemic envenomation is possible.

We analysed all calls concerning indigenous venomous snakebites recorded at the Swiss National Poisons Information Centre between 1997 and 2018, including all cases with identification by a herpetologist, and/or with compatible symptoms and circumstances of the exposure.

During the study period, 1,364 cases concerned snakebites. One third (466; 34%) were attributed to indigenous vipers. In 243 (52%) patients, medical follow-up information was available, with good causality between exposure and symptoms in 219 (90%) patients. Vipera aspis was identified in 77 of the cases (35%), Vipera berus in 54 (25%), and not further specified vipers in 88 (40%). In over two thirds of the 219 cases (155, 71%) adult patients were affected (male 109, female 46; median age 43 years [range 16-90]). Sixty-four patients were ctalization was 2 days (0-12 days).

Snakebites in Switzerland can result in severe symptoms, sometimes necessitating antivenom treatment.

In Switzerland, there has been a boom in the market for cannabidiol (CBD) products in recent years. However, little is known on the prevalence, modes of administration and motives for use of CBD products. The aim of the present study was to fill this gap using recent (2019) data from the Cohort Study on Substance Use Risk Factors (C-SURF).

Between April and December 2019, an unselected sample of 5233 Swiss young men from the French- and German-speaking regions (mean age 28.2 years, standard deviation 1.3) completed a self-report questionnaire covering measures of use of CBD products, modes of administration and motives to use of CBD, tetrahydrocannabinol (THC) and cigarettes. Descriptive statistics were used to estimate prevalence of self-reported use, modes of administration and motives to use CBD, whereas logistic regression models were used to test the associations of linguistic region, THC and tobacco use with use of CBD.

Lifetime and 12-month prevalence of self-reported use of CBD were 32.4% and 18d out of curiosity. CBD use was particularly prevalent among users of THC and cigarette smokers. CBD was most often used in combination with tobacco, thus exposing users to risks associated with smoking tobacco products.
Self-reported use of CBD is common among young Swiss men about one third used CBD in their life and about one in five in the previous 12 months. However, the vast majority of CBD users used it infrequently and out of curiosity. CBD use was particularly prevalent among users of THC and cigarette smokers. CBD was most often used in combination with tobacco, thus exposing users to risks associated with smoking tobacco products.
The number of laparoscopic liver resections is increasing worldwide, including in Switzerland. However, laparoscopy is mostly used for minor resections. Little is known about indications for and outcomes of major liver resections performed laparoscopically. The aim of this study was to compare the clinical outcome of open and laparoscopic major liver resection cohorts in two Swiss centres.

Patients undergoing open or laparoscopic major hepatectomy (>3 segments) in two cantonal hospitals from January 2015 to December 2019 were analysed. All disease types except perihilar cholangiocarcinomas, rare malignancies and resections with biliary reconstruction were included. The primary outcome was the number of complications incurred. Operation time, blood loss, hospital stay and 90-day mortality were secondary outcomes investigated. A separate analysis was performed for colorectal liver metastases, the most common indication. Potential risk factors for major complications were evaluated in a multivariate analyomplications and clinical non-inferiority compared with open major hepatectomy.
This first report from Switzerland evaluating outcomes of laparoscopic major hepatectomies showed no difference in complications and clinical non-inferiority compared with open major hepatectomy.
This retrospective study was conducted to (1) provide more modern data on real-life local management of metastatic rectal cancer; (2) compare therapeutic strategies; and (3) identify prognostic factors of local failure, overall survival and progression-free survival.

Data about efficacy and acute toxicity were collected. Patients were diagnosed with metastatic rectal cancer between 2004 and 2015, and were treated at least with radiotherapy. Local failure, overall survival and progression-free survival were correlated with patient, tumour and treatment characteristics using univariate and multivariate analyses.

Data of 148 consecutive patients with metastatic rectal cancer were analysed. Median follow-up was 19 months. Median overall survival was 16 months. All patients received local radiotherapy, with a median equivalent 2 Gy per fraction dose of 47.7 Gy. Rectal surgery was performed in 97 patients (65.6%). The majority of patients (86/97, 88.7%) received pre-operative chemoradiation. In multivariate analysis, rectal surgery was found to be the only independent predictor of increased overall survival (24.
