To compare fat suppression effectiveness, image quality and disease activity scores between MRI protocols based on the Dixon method and the Chemical Shift Selective (CHESS) technique in hands of patients with suspicion of early rheumatoid arthritis (RA).

Both hands of 28 patients (19 women; mean age 45.2 years old) with suspicion of early RA were prospectively imaged with Dixon- and CHESS-based OMERACT recommended protocols at 1.5 T including fat-suppressed T2-weighted and contrast-enhanced T1-weighted imaging. Two radiologists (R1/R2) separately assessed effectiveness of fat suppression and determined RAMRIS scores woth the Dixon- and CHESS-based protocols. R1 repeated the RAMRIS scoring and measured contrast-to-noise ratios (CNRs) on Dixon and CHESS images. Statistics included 2-way ANOVA test for the comparison of CNRs and Bland-Altman methodology for inter-technique and intra-observer agreement (p < 0.05).

Fat suppression failure occurred in up to 1 patient with the Dixon- and 25 patients with the CHESS-based protocols. CNRs were significantly higher on T1-weighted and lower on T2-weighted Dixon images than on the corresponding CHESS images (p ≤ 0.042). Median bias of the difference between Dixon- and CHESS-based RAMRIS scores was not significantly different from 0 (-0.8 to +1.0 and -1.1 to +1.4 for R1/R2). Median bias of the difference between RAMRIS scores at first and second readings was significantly different from 0 with the CHESS-based protocols (-0.8 to +1.7) but not with the Dixon-based protocols (+0.0 to +1.0).

Dixon sequences yield more effective fat suppression and more reproducible RAMRIS scoring than CHESS sequences in hands with suspicion of early RA.

The fungus was identified as Metarhizium pingshaense Q.T. Chen & H.L. Guo (Ascomycota Hypocreales) based on morphological characteristics and molecular studies. Scanning electron microscopic studies were conducted to study the infection of C. punctiferalis by M. pingshaense. Bioassay studies with purified conidial suspension proved that the isolate was highly virulent to C. punctiferalis, causing more than 86 % mortality to fifth instar larvae at 1 × 108 spores/mL, under laboratory conditions. The median lethal concentration (LC50) of the fungus against late instar larvae was 9.1 × 105 conidia/mL and the median survival time (MST) of late instar larvae tested at the doses of 1 × 108 and 1 × 107 conidia/mL were 4.7 and 6.4 days, respectively. The optimal temperature for fungal growth and sporulation was found to be 25 ± 1 °C. This is the first report of M. pingshaense naturally infecting C. punctiferalis. Isolation of a highly virulent strain of this fungus holds promise towards development of a potential mycoinsecticide against this pest.
Linkage to care for hepatitis C includes a new tool teleconsultation. Micro-elimination in prison is a recommendation and is feasible. An economic evaluation of telemedicine for hepatitis C virus (HCV) treatment in prisons has not yet been performed. This study aimed to provide a cost-minimization analysis comparing two strategies of HCV treatment in a prison telemedicine clinical practice (TCP) and the usual clinical practice (UCP).

An observational cost-minimization study was carried out on a cohort of inmates who received anti-HCV treatment in El Dueso prison (May 2016-November 2017). A decision tree was constructed, incorporating different clinical profiles according to the severity of the disease, the results of diagnostic tests, and treatment outcomes as well as the costs of each profile. Satisfaction with telemedicine was evaluated through an 11-question questionnaire with a 5-point Likert scale.

Seventy-five inmates were treated and underwent TCP with a follow-up of one year. The average cost per patient with the TCP strategy was €1,172 (€1,151 direct costs). Had UCP been carried out, the cost would have been €1,687 (€1,630 direct). Selleckchem Cordycepin Telemedicine consultation practice produced savings of €516 (30.6%) per patient, with total savings of €38,677. The transfer costs from prison to hospital represented the most important saving item, accounting for 99.3% of the TCP-related savings. The questionnaire revealed high levels of satisfaction with TCP, with a median score of 5 in each question. Sustained virological response rates were 94.7% after the first treatment and 100% after retreatment of the four relapses.

Telemedicine consultation practice is a more efficient strategy than UCP, mainly due to the reduction of transfer costs while preserving effectiveness and user satisfaction.

This study estimated legal products' share of Canada's total cannabis consumption during the first year of recreational legalisation, October 2018 to September 2019.

Government data was used to estimate monthly recreational sales in dollars per capita, grams per user, and percentage share of kilograms or litres consumed. As explanatory factors, the analysis considered provincial differences in retail pricing (percentage mark-ups) and store density (stores per million users), as well as national monthly production of dry cannabis (kilograms) and cannabis oil (litres) finished products.

Legal recreational products' share of Canada's overall cannabis consumption began at 7.8% in October 2018 and grew to 23.7% by September 2019, with an average of 14.5% over the first 12 months. Sales growth was delayed by shortages of both dry cannabis products and licensed stores, but not cannabis oils. Across the 10 provinces, legal recreational shares in September 2019 varied from 13% to 70%; differences in store densities and retail prices partly explained the variation.
