HBV precore (PC) and dual basal core promoter (BCP) mutations halt and downregulate HBeAg production respectively. PC mutation is rarely associated with HBV genotype A. We sought to examine the association of these variants with HBV genotypes, age and HBeAg status in a racially diverse population in North America.

Prospective study included 1036 (808 adults, 228 children) participants in the Hepatitis B Research Network. PC and BCP variants were determined by Sanger sequencing and dominant HBV species (>50%) were reported.

Median age was 36.3 years (range 2-80), 44.6% HBeAg(+), 74.2% Asians, 13.3% black and 9.7% white. The dominant PC variant was present in 29.4% participants including 20 with sub-genotype A1 or A2. 17/20 participants with genotype A and PC had a compensatory C1858T mutation. In the HBeAg(+) cohort, the prevalence of PC and/or BCP variants increased from 14.4% in the first 2 decades to 51% after 40 years of age. Among those aged 2-18, 52% and 83% with dominant PC and BCP variants werinfection significantly faster. This finding has potential clinical and therapeutic implications.The association between urticaria and different virus infections has been reported in many studies. Different virus infections have been reported to be comorbidities of spontaneous urticaria. In this paper, we report the case of a male patient with acute urticaria 7 days after he left the hospital where he was treated for coronavirus disease 2019 (COVID-19). This infection may act as a causative or a facilitating factor for the initiation of acute urticaria and additional cofactors such as stress may contribute for the urticaria phenotype to be expressed. Additional facts for severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus in future will clarify if urticarial rash is one of the COVID's multiple faces.Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) continues to be a rare diagnosis in children. Etiology, presentation, and management strategies are considerably different from adults. We report a fatal case of P-MAIVF with classical transthoracic and transesophageal echocardiographic findings complemented by CT imaging. The natural course of uncomplicated/asymptomatic P-MAIVF is largely unknown since most patients are offered surgery. NST-628 We present an extensive literature review of pediatric P-MAIVF and highlight important differences from the adult form of this disease.Extracts of kidney vetch (Anthyllis vulneraria L.) are becoming increasingly interesting as ingredients for the health and cosmetics industry. However, comprehensive phytochemical investigations of this plant are scant in the literature. Thus, the aim of the present work was an in-depth characterization of semi-polar constituents from A. vulneraria. To capture a broad spectrum of compounds, the aerial parts of A. vulneraria were extracted with EtOH/water and the resulting crude extracts fractionated by partition between AcOEt and BuOH. Secondary plant metabolites were analyzed by HPLC-ESI-MSn and GC/MS. In a fraction obtained from the BuOH extract via Amberlite® XAD-7 purification glycosides of kaempferol, quercetin, isorhamnetin and rhamnocitrin were detected by LC/MSn , besides flavonoids acylated with meglutol (3-hydroxy-3-methylglutaric acid), acetic and ferulic acids. Moreover, aglycons were analyzed in extracts after 1 N HCl hydrolysis and derivatization with BSTFA. GC/MS analysis of the hydrolysates revealed the incidence of compounds like meglutol, OH/OMe-substituted benzoic acids, ferulic and fatty acids, flavonoids, sugars and the triterpenoid medicagenic acid. Furthermore, a hemolytic activity was detected in the AcOEt extract using a blood-agar assay, and this was ascribed to the occurrence of saponins. In a saponin fraction, obtained from the AcOEt extract by chromatographic purification, two main saponins were characterized by LC/MSn and HR-ESI-MSn . A pure sapogenin could be isolated via VLC and CC purification upon acid hydrolysis of the saponins and assigned to saikogenin D by NMR analysis.

To describe cocaine treatment demand in 10 western European countries and to examine the size, direction and temporality of recent trends in the proportion of cocaine users among all clients entering treatment.

Aggregated data collected through the European Union standardized treatment demand monitoring system (TDI) between 2011 and 2018 were used.

Belgium, England, France, Germany, Ireland, Italy, Luxembourg, Spain, Switzerland and the Netherlands.

In total, more than 700 000 cocaine treatment records were analysed. Clients in treatment for cocaine as primary drug were predominantly male (85%), with an average age of 35years.

Number of treatment episodes for substance use and for cocaine as primary or secondary drug were collected year- and country-wise. When available, powder cocaine and crack and patients with and without previous treatment were differentiated.

Among the participating countries the share of cocaine as primary drug in treatment demand ranged between 4.7% [95% confidence intervaltial country-specific variation regarding cocaine prevalence and treatment demand, there has been an overall significant increase since 2015 in the share of cocaine-related treatment demand in western Europe.

To systematically review clinical and biochemical characteristics associated with the severity of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related disease (COVID-19).

Systematic review of observational studies from PubMed, ISI Web of Science, SCOPUS and Cochrane databases including people affected by COVID-19 and reporting data according to the severity of the disease. Data were combined with odds ratio (OR) and metanalysed. Severe COVID-19 was defined by acute respiratory distress syndrome, intensive care unit admission and death.

We included 12 studies with 2794 patients, of whom 596 (21.33%) had severe disease. A slightly higher age was found in severe vs non-severe disease. We found that prevalent cerebrovascular disease (odds ratio [OR] 3.66, 95% confidence interval [CI] 1.73-7.72), chronic obstructive pulmonary disease (OR 2.39, 95% CI 1.10-5.19), prevalent cardiovascular disease (OR 2.84, 95% CI 1.59-5.10), diabetes (OR 2.78, 95% CI 2.09-3.72), hypertension (OR 2.24, 95% CI 1.
