Background Both amisulpride and olanzapine are leading treatments for schizophrenia in China. This study aimed to investigate the long-term cost-effectiveness of amisulpride and olanzapine in the treatment of schizophrenia in China.Methods A decision-analytic Markov model was developed to simulate the lifetime clinical and economic outcomes of schizophrenia treatment from the healthcare payer perspective. The long-term costs and QALYs were estimated. Sensitivity analyses were performed to explore the impact of variance of parameters on the results.Results Treatment with amisulpride provided an effectiveness gain of 16.59 QALYs at an average cost of USD 25,884 whereas olanzapine resulted in 16.38 QALYs at a cost of USD 34,839 over a lifetime horizon. One-way sensitivity analysis suggested that the most sensitive variable was the unit cost of olanzapine. In a probabilistic sensitivity analysis based on a Monte Carlo simulation with a lifetime horizon, the probability of amisulpride being cost-effective was 99.8% at a willingness-to-pay threshold of USD 9,322, the GDP per capita in China 2018. A scenario analysis with updated olanzapine unit cost suggested an ICER of 7,857 USD/QALY.Conclusions Amisulpride is likely to be a cost-effective option with increased effectiveness compared with olanzapine in the treatment of schizophrenia patients in China.Background Moisturizers are cosmetic products used routinely to manage various skin conditions. Even though moisturizers are often thought to have minimal or no adverse reactions, allergic contact dermatitis (ACD) to these products can develop in some cases. Methods We studied ingredients included in 3 of the most commonly used moisturizer brands, identified their presence in standard patch testing series, and evaluated their allergenic potential, categorizing the allergens as frequent or infrequent. The standard patch testing series used as reference were the Thin-layer Rapid Use Epicutaneous patch test (T.R.U.E. test), the North American Contact Dermatitis Group (NACDG) screening standard series, and the American Contact Dermatitis Society (ACDS) core allergen series. Results Aveeno, Cetaphil, and Cerave products had a total of 12, 14, and 9 potential allergens, respectively, the majority of which were infrequent and not included in standard patch testing series. Conclusion Being aware of the allergenic potential of commonly used moisturizers may help healthcare providers when evaluating patients with ACD. Further testing is recommended in a targeted manner when suspecting ACD with negative standard patch testing series or when ACD is refractory to treatment.Introduction Rituximab, an anti-B-cell biological therapy, has been investigated in several clinical trials on antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs).Areas covered In this paper, the clinical trials and open-label studies on rituximab efficacy and safety in treating AAVs are reviewed.Expert opinion Rituximab achieved high remission-induction and sustained-maintenance rates for patients with these severe diseases, thereby challenging the cornerstone treatment of corticosteroids and cyclophosphamide followed by azathioprine. Rituximab should be used as first-line therapy with corticosteroids to induce remission of severe AAVs, especially in situations in which cyclophosphamide may be problematic (relapse after cyclophosphamide, women of childbearing age, risk of malignancy). Cyclophosphamide indications are likely to be restricted in the future. Whenever possible, rituximab should be preferred to azathioprine to maintain remission. The current maintenance regimen has been extended to at least 18 months but its optimal duration remains unknown and recent data suggest the possibility to extend treatment to 4 years. Future challenges include defining the best dose regimen at present, different schedules are used as alternatives to those recognized as standards by health authorities. In addition, it remains to identify which patients will benefit the most from long-term retreatment potentially those with relapsing disease or anti-proteinase-3 ANCA-positivity.OBJECTIVE The internal target volume (ITV) strategy generates larger planning target volumes (PTVs) in locally advanced non-small cell lung cancer (LA-NSCLC) than the Mid-position (Mid-p) strategy. We investigated the benefit of the Mid-p strategy regarding PTV reduction and dose to the organs at risk (OARs). METHODS 44 patients with LA-NSCLC were included in a randomized clinical study to compare ITV and Mid-p strategies. GTV were delineated by a physician on maximum intensity projection images and on Mid-p images from four-dimensional CTs. CTVs were obtained by adding 6 mm uniform margin for microscopic extension. CTV to PTV margins were calculated using the van Herk's recipe for setup and delineation errors. For the Mid-p strategy, the mean target motion amplitude was added as a random error. For both strategies, three-dimensional conformal plans delivering 60-66 Gy to PTV were performed. PTVs, dose-volume parameters for OARs (lung, esophagus, heart, spinal cord) were reported and compared. RESULTS With the Mid-p strategy, the median of volume reduction was 23.5 cm3 (p = 0.012) and 8.8 cm3 (p = 0.0083) for PTVT and PTVN respectively; the median mean lung dose reduction was 0.51 Gy (p = 0.0057). For 37.1% of the patients, delineation errors led to smaller PTV with the ITV strategy than with the Mid-p strategy. selleck chemicals CONCLUSION PTV and mean lung dose were significantly reduced using the Mid-p strategy. Delineation uncertainty can unfavorably impact the advantage. ADVANCES IN KNOWLEDGE To the best of our knowledge, this is the first dosimetric comparison study between ITV and Mid-p strategies for LA-NSCLC.Two naphthoquinone-derived heterodimers with unprecedented carbon skeletons, eleucanainones A (1) and B (2), were isolated from the bulbs of Eleutherine americana. Their structures were elucidated by comprehensive spectroscopic methods. The structures of 1 and 2 were determined to be the first examples of dibenzofuran- and naphthalenone-containing naphthoquinone dimers. Compound 1 exhibited significant anti-MRSA activity in vitro with minimum inhibitory concentration (MIC) values of 0.78 μg/mL by downregulation of basal expression of agrA, cidA, icaA and sarA in methicillin-resistant S. aureus (MRSA).
