The Valanginian stage (Early Cretaceous) includes an episode of significant environmental changes, which are well defined by a positive δ(13)C excursion. This globally recorded excursion indicates important perturbations in the carbon cycle, which has tentatively been associated with a pulse in volcanic activity and the formation of the Paraná-Etendeka large igneous province (LIP). Uncertainties in existing age models preclude, however, its positive identification as a trigger of Valanginian environmental changes...

BACKGROUND: Despite their experience of substance-related harm, few socially marginalized alcohol and other drug (AOD) users access substance use treatment. Thus, identifying alternative approaches for this population is important. This program evaluation documented substance use and health-related quality of life (QoL) following exposure to such an alternative approach: a harm-reduction drop-in center allowing alcohol consumption onsite. METHODS: Participants (N=85) were socially marginalized AOD users (e...

INTRODUCTION: The non-invasive vulvar Paget's disease is an intra-epidermal carcinoma with glandular characteristics. It appears like an erythematous plaque. The main symptoms are pruritus and pain. The standard treatment is surgical excision in depth. This treatment is complicated with a severe morbidity and photodynamic therapy can be an alternative choice. However, the pain experienced during the photodynamic treatment of vulvar lesion is intense and leads to a premature interruption of the treatment...

General wildlife health surveillance is a valuable source of information on the causes of mortality, disease susceptibility and pathology of the investigated hosts and it is considered to be an essential component of early warning systems. However, the representativeness of data from such surveillance programs is known to be limited by numerous biases. The roe deer (Capreolus capreolus capreolus) is the most abundant ungulate and a major game species all over Europe. Yet, internationally available literature on roe deer pathology is scarce...

INTRODUCTION: Smoking bans are considered one of the most effective policies to reduce population exposure to tobacco smoke and prevent adverse health outcomes. However, evidence on the effect of contextual variables on the effectiveness of smoking bans is still lacking. AIMS: The patchwork of cantonal smoke-free laws in Switzerland was used as a quasi-experimental setting to assess changes after their introduction in: hospitalisations and mortality due to cardiorespiratory diseases in adults; total hospitalisations and hospitalisations due to respiratory disorders in children; and the modifying effects of contextual factors and the effectiveness of the laws...

Similar to other institutions, the Swiss prison system faces a growing number of elderly prisoners, trends toward securitization, and, in consequence, more prisoners who will spend the end-of-life (EOL) period of time in prison. By law, prisoners should have the same access to care as the rest of the population. However, custody makes meeting the demands of medical and palliative care difficult. This article focuses on the organizational challenges related to EOL care. Based on ethnographic and documentary research, it examines the institutional logic of the prison and the competing "new" logic emerging with EOL care...

One of the major applications of critical metals (CMs) is in electrical and electronic equipment (EEE), which is increasingly embedded in other products, notably passenger vehicles. However, recycling strategies for future CM quantities in end-of-life vehicles (ELVs) are poorly understood, mainly due to a limited understating of the complexity of automotive embedded EEE. We introduce a harmonization of the network structure of automotive electronics that enables a comprehensive quantification of CMs in all embedded EEE in a vehicle...

We describe cases of collyriclosis in apodiform and passeriform birds in Portugal, Switzerland, and Germany. We extend the host range of Collyriculm faba to include apodiform birds ( Apus apus , Apus melba , and Apus pallidus ) and the passerine Sitta europaea (Eurasian Nuthatch). Infections varied in severity from an incidental finding to severe debilitation and death. The infection route remains unclear with the apparent absence from Germany, Portugal, and Switzerland of the first intermediate host of C. faba, the aquatic gastropod Bythinella austriaca, implying that other organisms might be involved in the parasite's life cycle...

Since its introduction into Europe the invasive Drosophila suzukii has established and spread widely, thereby entering habitats populated by native Drosophila species and their natural enemies. The highly prolific D. suzukii will likely interact with these species as a competitor, host or prey. To investigate potential interactions of D. suzukii with parasitoids, a field survey was conducted across several fruit-growing regions in Switzerland in two consecutive years. Eight species of hymenopteran parasitoids were collected using D...

Stockpiles of perfluoro-octane sulfonic acid (PFOS) containing aqueous film-forming foam (AFFF) have the potential to be emitted by leaching, spills, and during use in fire response and other processes. Several studies have discussed the high levels of stockpiled PFOS-containing AFFF and the risk they pose to the environment; however, there are large gaps in the amounts in Japan compared with other countries. For example, 300 tons are stockpiled in Canada, 2200-2600 tons in Switzerland, 1400 tons in Norway, and 19,000 tons in Japan from their reports for publication...

Previous references suggesting a high mortality of propofol addiction in medical personnel were mostly based on surveys of the heads of medical departments or case reports; therefore, a questionnaire was sent to 48 forensic medicine departments in Germany, Austria and Switzerland concerning the number of autopsies carried out between 2002-2112 on medical personnel with the suspicion of abuse of propofol or other analgesics. The response rate was 67%. In 16 out of the 32 responding departments 39 deaths (27 males) were observed with previous connections to anesthesiology, intensive care or emergency departments of which 22 were physicians, 13 nurses, 2 other personnel and 2 were unknown...

Secondary hyperparathyroidism is a complex disorder requiring an individualized multicomponent treatment approach. This study was conducted to identify treatment combinations used in clinical practice in Austria and Switzerland and the potential to control this disorder. A total of 333 adult hemodialysis and peritoneal dialysis patients were analyzed. All patients received conventional care prior to initiation of a cinacalcet-based regimen. During the study, treatment components, e.g. cinacalcet, active vitamin D analogues and phosphate binders, were adapted to individual patient requirements and treatment dynamics were documented...

OBJECTIVE: To more clearly define the efficiency and potential benefits of variable pulse-width laser technology for ureteroscopic lithotripsy, we performed comparative in vitro evaluations assessing stone comminution, laser fiber tip degradation, and stone retropulsion. METHODS: All experiments were conducted using a Swiss LaserClast Ho: YAG laser (Electro Medical Systems, Nyon, Switzerland) with adjustable pulse duration (300 µs - 1500 µs). To assess comminution efficiency and fiber tip degradation, a "dusting" model was employed; the laser fiber tip was moved by a 3-dimensional positioning system in a spiral motion across a flat BegoStone surface submerged in water...
