The COVID-19 pandemic has affected substance use and other addictive behaviour, however detailed insight is lacking.
Online questionnaire survey on the sample of 3,000 respondents aged 15+ randomly selected from the Czech internet panel using socio-demographic quotas was performed shortly after the end of confinement measures in May 2020 (response rate 35.4%). Questions covered current prevalence and patterns of substance use (i.e. in the last 12 months) and other forms of addictive behaviours as well as changes in their behaviour during the confinement measures. Responses were provided on categorical scale; a factor of 0 to 2 was assigned to the categories to quantify the changes where 1 means no change.
Respondents reporting the highest frequency of current use, especially the use of alcohol, cannabis and sedatives, further increased their intensity of use during the confinement measures by 5-10% on average, while less frequent users reduced it. The reduction of use during confinement measures increasoncerns gaming and social media. Without this insight the overall picture suggests rather overall reduction of consumption. Addiction treatment system should prepare for the increase of treatment demand following COVID-19 epidemic.
On 17th Dec 2019 gastroenteritis outbreak occurred in two Pragues neighbouring institutions. Investigation aimed to describe outbreak, identify etiological agent, vehicle and propose control measures.
Routine outbreak investigation and retrospective cohort study was done. Data collected via online questionnaire were analysed using descriptive, univariate and stratified analysis.
Of 960 employees, 276 responded (29%). We identified 39 (14%) cases, one tested norovirus positive. Canteen staff didnt report illness. No food item or environmental sample was tested. Sichuan pork served for lunch on 17th Dec was the most likely vehicle of outbreak (odds ratio (OR) 5.02, 95% confidence interval (CI) 1.98-12.64). Eating Sichuan pork and Chinese soup showed OR 31.5, 95% CI 5.0-320.7. Twenty-two (56%) cases can be explained by consumption of these food items.
Epidemiological analytical method provided evidence of likely vehicle. We did not find the source. Control measures were early ensured and outbreak ceased. We emphasise full outbreak investigation using analytical epidemiology, environmental screening and microbiological testing of cases and possibly all kitchen staff.

This study aims to determine the prevalence of latent tuberculosis infection (LTBI) in patients with moderate to severe rheumatoid arthritis (RA) who receive conventional and anti-cytokine therapy, to identify possible risk factors for tuberculosis (TB) and to evaluate the prophylactic treatment in positively screened patients.
We conducted an observational, retrospective study in patients with RA, who underwent LTBI screening (chest X-ray, tuberculin skin test and interferon gamma release assay test - IGRA test).
Out of 124 patients included, 7.25% of patients were diagnosed with LTBI during the treatment with conventional synthetic anti-rheumatic drugs in combination with glucocorticoids before initiation of anti-cytokine therapy. Another 21.77% were diagnosed during treatment with biologics or Janus kinase inhibitors. We confirmed the highest incidence of LTBI in TNF-treated group (66.66% LTBI positive patients), but also found positive screening in patients treated with other modalities. The mean LTlactic antituberculosis therapy in patients treated with conventional synthetic anti-rheumatic drugs in combination with glucocorticoids.Manufacturer instructions for 38% silver diamine fluoride (SDF) are limited to current FDA clearance for tooth desensitization. There is a need for instructions to provide best-practice recommendations for off-label use of SDF for caries prevention and arrest.
The authors considered existing clinical approaches to the use of 38% SDF at pH 10 for the prevention and arrest of active dental caries, in light of the best current evidence. Application of SDF, with or without subsequent direct restoration, is included. The content was reviewed by stakeholders including but not limited to those listed on the consensus statement (Appendix A, below).
38% SDF for the prevention and arrest of active caries lesions, as well as compatibility with common direct restorative materials, such as glass-ionomer cement and resin composite, has a foundation in the scientific literature. A practical decision-flow diagram and accompanying best practices for treatment of caries lesions, based on clinical access and intention to restore, were developed based on available evidence and expert clinical observation when no evidence was available.
Based on the best available evidence, a logical approach can be adopted regarding the practical use of 38% SDF for caries prevention and arrest.
SDF used as per these instructions for prevention on high-risk tooth surfaces and arrest of active caries lesions has a place in the practitioner's dental caries management armamentarium. When SDF is applied to active lesions, it can be used with or without subsequent restoration, depending on clinical context, expert judgment, and patient input.

Not only are providers adopting AI at a rapid pace, payers are tapping this technology to automate their claims review operations and reduce friction in provider interactions. In part three of this six-part dental AI series, the authors offer their view from the frontlines of dental claims processing and the promising future impact of AI. Representing clinical and business viewpoints, the authors draw on experience working at and with some of the largest dental payers in the country. This article presents a forward-looking perspective on the potential of dental AI to improve payer-provider relations, streamline claims review, and ultimately provide an improved patient experience.Due to the abundance and easy availability of solar energy resources, solar-driven water evaporation provides a sustainable way to obtain clean water from wastewater and seawater. However, achieving a high evaporation rate with excellent light absorption remains a critical challenge in the structural regulation of evaporators. Herein, inspired by the natural transpiration process in plants (blue spruce), we designed a three-dimensional (3D) cone-shaped solar steam generator based on vertical polypyrrole nanowires-coated fabric (VPPyNWs-fabric). The microstructure design of polypyrrole (PPy) increases the solar energy absorption of the incident light through multiple reflections between the VPPyNWs, while the macrostructure design of the 3D evaporator possesses an enlarged surface area for energy harvesting, wide path for water supply, and open structure for vapor diffusion. As a proof of concept, the as-obtained 3D VPPyNWs-fabric-based solar steam generator demonstrates a fast water evaporation rate of 2.32 kg m-2 h-1 with high solar absorption of 97% and solar-to-vapor conversion efficiency of 98.56% at 1 kW m-2 energy density. In addition, the solar steam generator can be steadily applied in various water conditions, e.g., seawater, dye wastewater, and acidic and alkaline wastewater. This high-performance evaporator via 3D macro- and microstructure design offers a new avenue for better utilization of solar energy.Sphingomyelinase (SMase) is closely related to diseases like Niemann-Pick disease and atherosclerosis, and the development of a simple method for the assay of SMase activity is very useful to screen new potential inhibitors or stimulators of SMase or biomarkers of disease. Fluorophore-encapsulated nanoliposomes (FENs) are emerging as a new fluorescent probe for sensing the enzymatic activity. In this work, two fluorochromes (cy7 and IR780) were encapsulated into the liposome of sphingomyelin, and therefore, a sphingomyelin-based ratiometric FEN probe for the SMase activity assay was constructed. The probe shows high selectivity and sensitivity to acid SMase with a detection limit of 4.8 × 10-4 U/mL. Sphingomyelin is the natural substrate of SMase; therefore, the probe has native ability for all kinds of SMase activity assays. Moreover, the probe has been successfully applied to the analysis of acid SMase activity in cells and urine samples. As far as we know, this is the first example of a nanoliposome fluorescence method for assaying acid SMase, and the method is biocompatible and much simpler than the existing ones, which might provide a new strategy for developing new methods for other important esterases.Pea protein isolate nanoparticles (PPINs) were successfully prepared by potassium metabisulfite (K2S2O5). The disulfide bonds were disrupted by K2S2O5, and then the PPINs were formed through self-assembly. The average diameter of PPINs increased from 124.7 to 297.5 nm as the concentration of K2S2O5 was increased from 2 to 8 mM, and the PPINs showed higher ζ-potentials (-32.2 to -35.8 mV) and unimodal distribution. The content of free sulfhydryl groups first increased and then decreased with the fracture and reformation of disulfide bonds. Subsequently, the increase of the β-sheet, which has considerable hydrophobicity, promoted the formation of PPINs. The formation mechanism of PPINs was explored by dissociation tests hydrophobic interactions maintained the basic skeleton of PPINs, disulfide bonds stabilized the internal structure, and hydrogen bonds existed on the exterior of the particles. This study provided a simple and economical method to fabricate nanoparticles.The accurate quantification of triterpenoids in Ganoderma lucidum mushroom in the mycelium stage is challenging due to their low concentrations, interference from other possible isomers, and the complex matrix. Here, a high-resolution quadrupole-time-of-flight mass spectrometry "multiple reaction monitoring" with target enhancement (HR-QTOF-MRM) method was developed to quantify seven target triterpenoids in G. lucidum. The performance of this method was compared against an optimized QQQ-MRM method. The HR-QTOF-MRM was shown to be capable of distinguishing target triterpenoids from interferent peaks in the presence of matrices. The HR-QTOF-MRM LOD and LLOQ values were found to be one to two times lower than those derived from the QQQ-MRM method. Intraday and interday variabilities of the HR-QTOF-MRM demonstrated better reproducibility than the QQQ-MRM. In addition, excellent recoveries of the analytes ranging from 80 to 117% were achieved. Spiking experiments were carried out to verify and compare the quantitative accuracy of the two methods.
