PURPOSE OF REVIEW The lack of fully effective therapies to alter the natural course of myelodysplastic syndromes (MDS) leads to chronic morbidity, mortality and affects quality of life (QoL). Since existing therapies outside of hematopoietic cell transplantation (HCT) are not curative, there is a growing interest in incorporating patient-reported outcomes (PROs) as meaningful endpoints for these patients in research and clinical practice. RECENT FINDINGS Currently, there are limited numbers of studies reporting the impact of MDS therapeutics on PROs to guide clinical decision-making and increase patient satisfaction. However, clinical trials that have incorporated QoL outcomes have demonstrated positive results with the use of growth factors, hypomethylating agents, and lenalidomide. Here we review and highlight the importance of harnessing the power of PROs as part of a comprehensive efficacy evaluation to ultimately deliver superior patient-centered care across the spectrum of MDS. Wnt inhibitor As our understanding of MDS continues to increase, adapting the metrics of these outcome measurements will be equally important as the alteration of the natural history in developing new therapies.Substance use (SU) rates among American Indian (AI) adolescents have been greater than national rates for decades, with little progress made on reducing them. Reasons for this may include lack of evidence on which to base effective interventions, the uniqueness of this population, and the overall lack of attention that this population has received in reducing socioeconomic and health disparities. Moreover, there has been limited focus on understanding how positive individual characteristics may serve as protective factors for AI adolescents. Using data from 379 AI youth living on or near four northern plains reservations, the current study examines the relationship between future orientation (FO) and self-determination (SD) and intentions to use alcohol and marijuana, with negative consequences of SU for future goals and autonomy evaluated as potential mediators. SEM models were estimated for alcohol use and marijuana use intentions, with two separate models for each dependent variable-one assessing the direct and indirect effects of FO via perceived consequences for future goals and the other assessing the effects of SD via perceived consequences for autonomy. All models displayed good fit, but the pattern of significant effects varied by substance, by construct (FO vs. SD), and by gender. Findings suggested that SD, and more proximally, perceived consequences of use for autonomy, may be particularly useful promotive factors to target SU prevention in AI adolescents. Culturally congruent interventions designed to promote SD and autonomous motivations to abstain may be particularly impactful within a young AI adolescent population, as early adolescence represents a critical period of development for personal autonomy and identity.The fate of carbaryl in the Seto Inland Sea (west Japan) was predicted using a mass distribution model using carbaryl concentrations in river and sea water samples, degradation data, and published data. The predicted carbaryl concentrations in water in Kurose River and the Seto Inland Sea were 4.320 and 0.2134 μg/L, respectively, and the predicted concentrations in plankton, fish, and sediment were 0.4140, 2.436, and 1.851 μg/g dry weight, respectively. The carbaryl photodegradation and biodegradation rates were higher for river water (0.330 and 0.029 day-1, respectively) than sea water (0.23 and 0.001 day-1, respectively). The carbaryl photodegradation rates for river and sea water (0.33 and 0.23 day-1, respectively) were higher than the biodegradation rates (0.029 and 0.001 day-1, respectively). The hydrolysis degradation rate for carbaryl in sea water was 0.003 day-1, and the half-life was 231 days. Land (via rivers) was the main source of carbaryl to the Seto Inland Sea. The model confirmed carbaryl is distributed between sediment, plankton, and fish in the Seto Inland Sea. Degradation, loss to the Open Ocean, and sedimentation are the main carbaryl sinks in the Seto Inland Sea, accounting for 43.81, 27.90, and 17.68%, respectively, of total carbaryl inputs. Carbaryl source and sink data produced by the model could help in the management of the negative impacts of carbaryl on aquatic systems and human health.Lemna minuta Kunth was used to remove Cr(VI) from aqueous solutions, and some of the mechanisms involved in this process were analyzed. In addition, the cellular signaling mediated by phospholipase D activity as well as antioxidant responses was also evaluated during the process. Cr(VI) removal efficiencies were 40% for 0.5 mg/L, after 24 h, and up to 18% at metal concentrations as high as 5 mg/L. Removal mechanisms displayed by these macrophytes include bioadsorption to cell surfaces and, to a greater extent, Cr internalization and bioaccumulation within cells. Inside of them, Cr(VI) was reduced to Cr(III), a less toxic form of this metal. At the first hours of Cr(VI) exposure, plants were able to sense chromium, activating membrane signal transduction pathways mediated by phospholipase D and phosphatidic acid. Moreover, an increase in the activity of antioxidant enzymes such as superoxide dismutases and peroxidases was observed in the same time. These and other components of the antioxidant defense system would help to reduce the stress generated by the metal. The toxicity of the products formed during the removal process was assessed through Lactuca sativa L. and AMPHIAGU test. It was evidenced that Cr(VI) phytoremediation process by L. minuta plants did not generate acute toxicity neither for L. sativa seeds nor for embryos of Rhinella arenarum (Hensel, 1876). Thus, L. minuta plants could be considered as valuable species for the treatment of waters contaminated with Cr(VI).Valorisation of organic wastes to produce industrially relevant commodity products is a sustainable, cost-effective and viable alternative providing a green platform for chemical production while simultaneously leading to waste disposal management. In the present study, organic wastes such as agricultural residue-derived sugars, oilseed meals, poultry waste and molasses were used for substituting expensive organic fermentation medium components. Moorella thermoacetica and Aurantiochytrium limacinum were adapted on these waste-derived hydrolysates to produce high volume-low value products such as bio-acetic acid (80% theoretical yields) and oil-rich fish/animal feed (more than 85% dry cell weight as compared with conventional nutrient sources) respectively. Use of these waste-derived nutrients led to ~ 75% and ~ 90% reduction in media cost for acetic acid and oil-rich biomass production respectively as compared with that of traditionally used high-priced medium components. The strategy will assist in the cost reduction for high volume-low value products while also ensuring waste recovery.
