By decorating ∼5-7 nm Au nanoparticles evenly on the inner surface of the porous SiO2 shells (i.e., S@Au@SiO2), electron transport is enhanced, with consequently enhanced sulfur conversion kinetics at high current rates. Studies of battery performance showed that the S@SiO2 cathode can deliver an initial capacity of 1153 mA h g-1 under 0.2 C and retain 816 mA h g-1 after 100 cycles. More importantly, the Au-decorated S@Au@SiO2 cathode can deliver a high capacity of 500 mA h g-1 under 5 C.Organic micropollutants (MPs) are increasing in number and concentration in water systems as a result of human activities. Often from human origin, these micropollutants build up in the environment because organisms lack the mechanisms to metabolize these substances, which cause negative health, ecological, and economic effects. Adsorption-based remediation processes for these compounds often rely on activated carbon materials. However, activated carbons are ineffective against certain MPs, exhibit low removal efficiencies in the presence of common aqueous matrix constituents, and require energy-intensive activation and regeneration processes. To overcome the deficiencies of traditional technologies, novel adsorbents based on molecular receptors offer promising alternative solutions. This Account describes the recent development of polymer adsorbents based on molecular receptors for removing trace organic chemicals from water. Polymer networks based on molecular receptors have high binding affinities for manymethods to create larger and more uniformly sized particles for use in flow-through applications are described here. β-Cyclodextrin polymers are useful for trapping organic micropollutants such as bisphenol A, perfluorooctanoic acid, and many kinds of pharmaceuticals and pesticides, but their binding pockets are too large to capture micropollutants that are small or of high polarity. Other molecular receptors such as resorcinarene cavitands can target lower-molecular-weight MPs, including halomethane disinfection byproducts and industrial solvents, that are not bound strongly by β-cyclodextrins. learn more These materials demonstrate the potential of expanding the library of polymers based on molecular receptors. Overall, these emerging adsorbents show promise for the removal of legacy and emerging MPs from water, as well as the ability to rationally tune the adsorbent's structure to target the most persistent and toxic MPs.The spin-spin interactions between unpaired electrons in organic (poly)radicals, especially nitroxides, are largely investigated and are of crucial importance for their applications in areas such as organic magnetism, molecular charge transfer, or multiple spin labeling in structural biology. Recently, 2,2,6,6-tetramethylpiperidinyloxyl and polymers functionalized with nitroxides have been described as successful redox mediators in several electrochemical applications; however, the study of spin-spin interaction effect in such an area is absent. This communication reports the preparation of a novel family of discrete polynitroxide molecules, with the same number of radical units but different arrangements to study the effect of intramolecular spin-spin interactions on their electrochemical potential and their use as oxidation redox mediators in a Li-oxygen battery. We find that the intensity of interactions, as measured by the d1/d electron paramagnetic resonance parameter, progressively lowers the reduction potential. This allows us to tune the charging potential of the battery, optimizing its energy efficiency.Hyper-cross-linked microporous organic polymers are a class of porous materials that have captured widespread attention owing to their high surface areas and wide range of monomeric sources. Balancing economy with performance is the initial hurdle when designing effective hyper-cross-linked microporous organic polymers. Herein, we demonstrated an inexpensive sulfurated solvent-knitted hyper-cross-linked microporous polymer scaffold, named sulfur-decorated hyper-cross-linked coal tar (CTHP-SES), utilizing coal tar as an aromatic monomer with numerous positions for potential chelation of toxic metals, particularly mercury, from water. The resulting material illustrated selective adsorption of mercury from both water (1037 mg g-1) and the gas phase (416 mg g-1) with rapid kinetics (183.67 mg min-1 g-1), good recyclability (4 runs), and excellent stability under both strong basic and acidic conditions. CTHP-SES was able to reduce the concentration of the Hg(II) solution from 1 mg L-1 to 32 μg L-1 after 10 min due in part to the promising distribution coefficient (Kd = 2.371 × 106 mL g-1). These results show that CTHP-SES offers a promising and practical platform to cope with a variety of environmental contaminations.
The aim of this study was to assess quantitative ultra-high b-value (UHB) diffusion magnetic resonance imaging (MRI)-derived parameters in comparison to standard clinical apparent diffusion coefficient (SD-ADC-2b-1000, SD-ADC-2b-1500) for the prediction of clinically significant prostate cancer, defined as Gleason Grade Group greater than or equal to 2.

Seventy-three patients who underwent 3-T prostate MRI with diffusion-weighted imaging acquired at b = 50/500/1000/1500s/mm2 and b = 100/500/1000/1500/2250/3000/4000 s/mm2 were included. Magnetic resonance lesions were segmented manually on individual sequences, then matched to targeted transrectal ultrasonography/MRI fusion biopsies. Monoexponential 2-point and multipoint fits of standard diffusion and of UHB diffusion were calculated with incremental b-values. Furthermore, a kurtosis fit with parameters Dapp and Kapp with incremental b-values was obtained. Each parameter was examined for prediction of clinically significant prostate cancer using bootstrapation of a large b-value range and inclusion of 2-point, multipoint, and kurtosis models, none of the parameters provided better predictive performance than standard 2-point ADC measurements using b-values 50/1000 or 50/1500. Our results suggest that most of the diagnostic benefits available in diffusion MRI are already represented in an ADC composed of one low and one 1000 to 1500 s/mm2 b-value.

To determine the personnel costs and revenue generated by embedding a behavioral health nurse practitioner (BHNP) in primary care clinics to evaluate and manage adolescent behavioral health needs.

We estimated personnel costs and revenue from a quality improvement project undertaken at 4 clinic sites between August 1, 2016, and July 31, 2018, at a large multispecialty medical group in northern California.

Costs were estimated by identifying the actual hours spent by the BHNP and for medical assistant (MA) support and using Bureau of Labor Statistics national data on wages and benefits. Revenue was estimated by analyzing Current Procedural Terminology (CPT) codes for BHNP visits from the Epic electronic health record and corresponding relative value units (RVUs), based on 135% of 2018 nationally unadjusted Medicare rates.

We estimate 2-year revenue of $144,449 and personnel costs (salary + benefits) of $90,431. The BHNP work totaled 1083 hours, and MA support totaled 312 hours. Using a nurse practitioner wage of $53.70/hour and an MA wage of $16.95/hour, total salary costs were $63,451; we then added benefits costs. Using the CPT codes assigned to the 768 encounters with 207 unique patients, we estimated generation of 1640 RVUs and total revenue of $144,449.

This analysis found that personnel costs ($90,514) of a primary care-embedded BHNP are 63% of the potential revenue generated ($144,449). This analysis suggests that a primary care BHNP could be a cost-saving and patient-centered way to reduce the burden on primary care providers while meeting the growing needs of adolescents with behavioral health needs.

It is unclear on what basis Medicare drug plans impose coverage restrictions on orphan drugs. This study aims to investigate the factors associated with utilization controls in Medicare fee-for-service Part D formularies.

Cross-sectional analysis.

We used multivariate logistic regression to assess the association between orphan drug characteristics and use of formulary utilization controls in 2016. We controlled for number of beneficiaries per drug, exclusivity expiration, and the number of plans and beneficiaries per formulary. We conducted sensitivity analyses using fixed and random effects.

On average, 85% of orphan drugs on a formulary were placed on its highest cost-sharing tier and 76% were subject to prior authorization (PA). Orphan drugs with annual costs of $50,000 or more had twice the odds of having PA requirements compared with less expensive ones. Relative to orphan drugs with a single indication, drugs with multiple indications were more likely to have restrictions. Less effective drugs had 1.5 times the odds of highest tier placement relative to more effective drugs. The presence of black box warnings and patient assistance programs were associated with more restricted access. Orphan drugs with generics were less likely to undergo restrictions than those without generics (all P < .05).

Plans are making evidence-based decisions by rewarding more clinically effective and safer orphan drugs. They are penalizing drugs with multiple indications. Surprisingly, plans place fewer restrictions on orphan drugs that have a generic equivalent, which may further discourage generic entry into the orphan space, where competition is already sparse.

Value co-creation focuses on customer participation and co-creates value with suppliers. Patients' support and cooperation can improve the quality of medical care. Value creation is closely related to participants' behavior. The DART (Dialogue, Access, Risk assessment, Transparency) model is widely used in commercial research because it defines and classifies value co-creation behavior clearly and systematically. However, there is little research using the DART model in the field of health care. This study aimed to develop and evaluate the psychometric properties of a scale measuring patient value co-creation behavior based on the DART model.

The Delphi technique was used to determine the scale content with a panel of 17 experts. A cross-sectional survey was administered to 356 outpatients and inpatients of a hospital in Guangzhou, China.

Internal consistency reliability and composite reliability (CR) were used to estimate the scale's reliability. Validity was assessed using convergent and discriminant validity.
