Improving tuberculosis management in prisons: impact of a rapid molecular point-of-care test
Tuberculosis (TB) remains a major global public health problem. In 2018, TB was responsible for about 1.5 million deaths according to the World Health Organization (WHO) with notification of 10 million cases1. In Europe, the frequency of TB varies considerably from country to country, mainly in Eastern Europe, with countries reporting rates ranging from 2.6/100,000 in Liechtenstein to 66.2/100,000 in Romania2. France reports 5,092 new cases per year and Ile-de-France is the Metropolitan region with the highest incidence rate (16.1 cases per 100,000 inhabitants in 2018)3. (Source: Journal of Infection)

Flattening the curve in 52 days: characterisation of the COVID-19 pandemic in the Principality of Liechtenstein - an observational study.
CONCLUSION: The close collaboration of all relevant stakeholders allowed for the complete workup of all COVID-19 patients nationwide. A multitude of factors (e.g., young age of the patients, low-threshold access to testing, close monitoring of cases, high alertness and adherence to public health measures by the population) led to the early containment of the first wave of the pandemic, with a very low rate of serious outcomes. Antibody testing for SARS-CoV-2 revealed a substantial proportion of undiagnosed COVID-19 cases among close contacts of the patients. PMID: 33105020 [PubMed - as supplied by publisher] (Source: ...

Recent trends in money laundering
AbstractThis paper illustrates how criminals currently launder money in Germany, Liechtenstein, and Switzerland. Semi-structured expert interviews were conducted with 50 money launderers and 50 compliance and prevention experts, whose responses were subjected to qualitative content analysis. Based on the findings therefrom, a quantitative survey of 200 compliance officers was conducted. Together, these two methods revealed the concrete techniques currently used to launder money in Europe. Contrary to popular belief, money laundering is found not to be associated with high costs, and can even generate significant profits. A...

Myeloid-Derived Suppressor Cells in Lung Transplantation
In conclusion, circulating MDSCs are measurable, functional and have a G-MDSC phenotype in lung transplant patients. Their frequency is increased in stable patients, decreased during post-transplant complications, and related to level of immunosuppression. This study may pave the way for further investigations of MDSC in the context of lung transplantation. Introduction From a transplant immunological point of view, graft acceptance is the fundamental element in allograft survival. Graft acceptance is realized by blocking the immune system with immunosuppression preventing host immune cells to recognized and attack...

In this study, we explored the proliferation of microbial communities on R. exoculata broods through embryonic development using a combination of NGS sequencing and microscopy approaches. Variations in abundance and diversity of egg microbial communities were analyzed in broods at different developmental stages and collected from mothers at two distinct vent fields on the Mid-Atlantic Ridge (TAG and Snake Pit). We also assessed the specificity of the egg microbiome by comparing communities developing on egg surfaces with those developing on the cuticle of pleopods, which are thought to be exposed to similar environmental c...

We analysed notifications of imported confirmed malaria cases between 2005 and 2015 in Switzerland or Liechtenstein. Data for previously visited countries, nationality and reason for travelling were analysed. In contrast with the impressive drop of malaria cases reported worldwide since 2000, we found that the number of malaria cases imported yearly in Switzerland doubled in 2014 and 2015 compared to the average for the preceding decade. Since 2014, Plasmodium vivax infection represented 36% of ...

However, all the scientific and medical efforts dedicated to this have not resulted in the expected success. In fact, classical antineoplastic treatments such as surgery, radio and chemotherapy are still first line treatments. Even so, there is a quantity of experimental evidence demonstrating that cancer cells are immunogenic. However, the effective activation of anti-cancer T cell responses closely depends on an efficient antigen presentation carri...

Water Sorption, Solubility, and Color Stability of Giomer Restoratives
This study compared the color stability, water sorption, and solubility of a giomer composite and two nanohybrid composite resins. Materials and MethodsDisc‐shaped specimens (1‐mm thickness × 15‐mm diameter) of a giomer (Beautifil II, Shofu, Kyoto, Japan) and two nanohybrid (Filtek Z550, 3M ESPE, St. Paul, MN, USA; Tetric N‐Ceram, Ivoclar Vivadent, Schaan, Liechtenstein) composites (N = 10) were prepared. Baseline color measurements were taken, and specimens were immersed in water for 28 days. Following immersion, color values were remeasured, and color‐change values (ΔE) w...

Overview of 71 European community-based initiatives against childhood obesity starting between 2005 and 2011: general characteristics and reported effects
Conclusions: Despite diversity of included CBIs, common characteristics were the application of integrated actions at a local level, aimed at changing the environment and the children's behaviour directly. Evidence supporting effectiveness on weight indicators is available, although the design and conduct of most of these studies were suboptimal (i.e. no control group, a small sample size, not random).

The Effects of Mouth Rinses on the Color Stability of Resin‐Based Restorative Materials
Abstract ObjectiveThe aim of this study was to assess the color stability of three direct resin‐based restorative materials: IPS Empress Direct (Ivoclar Vivadent, Schaan, Liechtenstein), Nano‐filled composite (Filtek Z 350 XT, 3 M ESPE, St. Paul, MN, USA), and Nano‐hybrid composite (Tetric Evo Ceram, Ivoclar Vivadent, Schaan, Liechtenstein) upon immersion into the following three mouth rinses: Antiseptol (Kahira Pharmaceuticals and Chemical Industries Co. Cairo‐Egypt), Flucal (Alexandria Co. Pharmaceuticals Alexandria, Egypt), and Listerine (Johnson & Johnson, UK). Materials and MethodsNinety disc‐shap...
