Sodium vanadate NaV6O15 (NVO) is one of the most promising cathode materials for sodium-ion batteries because of its low cost and high theoretical capacity. Nevertheless, NVO suffers from fast capacity fading and poor rate capability. Herein, a novel free-standing NVO/multiwalled carbon nanotube (MWCNT) composite film cathode was synthesized and designed by a simple hydrothermal method followed by a dispersion technique with high safety and low cost. The kinetics analysis based on cyclic voltammetry measurements reveals that the intimate integration of the MWCNT 3D porous conductive network with the 3D pillaring tunnel structure of NVO nanorods enhances the Na+ intercalation pseudocapacitive behavior, thus leading to exceptional rate capability and long lifespan. Furthermore, the NVO/MWCNT composite exhibits excellent structural stability during the charge/discharge process. With these benefits, the composite delivers a high discharge capacity of 217.2 mA h g-1 at 0.1 A g-1 in a potential region of 1.5-4.0 V. TAK875 It demonstrates a superior rate capability of 123.7 mA h g-1 at 10 A g-1. More encouragingly, it displays long lifespan; impressively, 96% of the initial capacity is retained at 5 A g-1 for over 500 cycles. Our work presents a promising strategy for developing electrode materials with a high rate capability and a long cycle life.Sequence-specific nucleic acids recognizing low-molecular-weight ligands or macromolecules (aptamers) have found growing interest for biomedical applications. The present review article summarizes recent applications of aptamers as stimuli-responsive gating units of drug (or dye)-loaded nano- or microcarriers for controlled and targeted drug release. In the presence of cellular biomarkers, the nano-/microcarriers are unlocked by forming aptamer-ligand complexes. Different aptamer-functinalized nano-/microcarriers are presented, including inorganic nanomaterials, metal-organic framework nanoparticles, and soft materials. The chemistries associated with the preparation of the carriers and the mechanisms to unlock the carriers are discussed. Stimuli-responsive gated drug-loaded micro-/nanocarriers hold great promise as functional sense-and-treat materials for the targeted and selective release of drugs.Numerous studies have found that the surface topography affects the material antibacterial properties by reducing the attachment of bacteria on the surfaces without influencing the viability of the adhered cells. For Cu-bearing alloys with excellent contact-killing properties, bacterial adhesion on the surface is also accompanied by short-range interactions which regulate the toxic effects of the material surface against bacterial cells. Thus, the surface topography of Cu-bearing alloys, as an important factor dominating the exposure level of bacteria on the surfaces, should affect the subsequent contact-killing efficiency. In this work, our major focus was on the regulation mechanism of the surface features on the material-bacterial interactions. We correlated the surface properties including different surface roughnesses of Cu-bearing stainless steel (SS) with the bacterial damage pattern and attempted to clarify the role of surface roughness in mediating the contact-killing behavior of Cu-bearing SS. The results of both atomic force microscopy and scanning electron microscopy investigations showed that E. coli cells experienced the most rapid physical and mechanical damages after incubating with the diamond-polished Cu-bearing SS surface. The bacterial cells noticeably stiffened and the adhesion force significantly increased, as evidenced by force-distance curve measurements. Because of the enhanced hydrophobicity and higher surface potential of the diamond-polished surface, which strengthened the Lewis acid-base attractive forces and weakened the electrostatic barrier between the bacteria and the surface, a higher exposure surface for bacteria was generated. link2 Furthermore, the contact-induced charge transfer, manifested by Cu ion burst release, and reactive oxygen species overexpression contribute to an efficient contact-killing process.Adsorption-driven heat transfer devices incorporating an efficient "adsorbent-water" working pair are attracting great attention as a green and sustainable technology to address the huge global energy demands for cooling and heating. Herein, we report the improved heat transfer performance of a defective Zr fumarate metal-organic framework (MOF) prepared in a water solvent (Zr-Fum HT). This material exhibits an S-shaped water sorption isotherm (P/P0 = 0.05-0.2), excellent working capacity (0.497 mLH2O mL-1MOF) under adsorption-driven cooling/chiller working conditions (Tadsorption(ads) = 30 °C, Tcondensation (con) = 30 °C, and Tdesorption(des) = 80 °C), very high coefficient of performances for both cooling (0.83) and heating (1.76) together with a relatively low driving temperature at 80 °C, a remarkable heat storage capacity (423.6 kW h m-3MOF), and an outstanding evaporation heat (343.8 kW h m-3MOF). The level of performance of the resultant Zr-Fum HT MOF is above those of all existing benchmark water adsorbents including MOF-801 previously synthesized in the N,N-dimethylformamide solvent under regeneration at 80 °C which is accessible from the solar source. This is coupled with many other decisive advantages including green synthesis and high proven chemical and mechanical robustness. The microscopic water adsorption mechanism of Zr-Fum HT at the origin of its excellent water adsorption performance was further explored computationally based on the construction of an atomistic defective model online with the experimental data gained from a subtle combination of characterization techniques.
To estimate the costs associated with home administration of oral paclitaxel and encequidar (novel P-glycoprotein pump inhibitor allowing oral paclitaxel bioavailability) compared with clinic/office administration of intravenous (IV) paclitaxel (175 mg/m2) and protein-bound paclitaxel in US patients with metastatic breast cancer.

Economic analysis.

A cost calculator was constructed from a payer's perspective including all costs related to administration of the chemotherapies, including drug administration, premedications and concomitant medications, oncologist office visits, laboratory testing, and administration-related adverse events. Total administration cost per patient per month (PPPM) and 6-month costs per patient were estimated for oral paclitaxel and encequidar, 175 mg/m2 IV paclitaxel, and protein-bound paclitaxel. Three scenarios for oral paclitaxel and encequidar, a weekly IV paclitaxel scenario (80-100 mg/m2), and univariate sensitivity analyses were conducted.

Home administration of oral avings for payers.
Home administration of oral paclitaxel and encequidar was associated with lower administration costs compared with once-every-3-weeks IV paclitaxel (175 mg/m2) and protein-bound paclitaxel, resulting in potential cost savings for payers.
Intravenous (IV) taxanes for metastatic breast cancer (mBC) are associated with toxicities, such as chemotherapy-induced peripheral neuropathy (CIPN), which can detrimentally impact outcomes.

To assess the impact of CIPN on clinical and economic outcomes in women with mBC, initiating IV paclitaxel/ nab-paclitaxel.

Adult women in the MarketScan Commercial and Medicare Supplemental Database with a mBC diagnosis, initiating IV paclitaxel or IV nab-paclitaxel (index date = first administration) from November 1, 2013, to September 30, 2018, who had no prior neuropathy diagnoses, and continuous enrollment 12 months prior to and ≥ 3 months following index were selected. Propensity score-matched CIPN and non-CIPN cohorts were defined, based on postindex CIPN diagnosis. Clinical characteristics and all-cause and breast cancer (BC)-related health care utilization and costs per patient per month (PPPM) were compared between matched CIPN and non-CIPN cohorts during follow-up.

Among the 5870 women with mBC initiatevelopment of comorbidities, and elevated health care costs. Therapies for mBC that offer increased tolerability are needed to help improve patient outcomes and control costs.
Intravenous (IV) taxane therapy for metastatic breast cancer (mBC) has been associated with toxicities and demanding dosing schedules, which can limit treatment effectiveness.

To assess treatment patterns, toxicities, and costs in women with mBC initiating IV paclitaxel or IV nab-paclitaxel.

Adult women diagnosed with BC from January 1, 2014, to September 30, 2018, were identified in the MarketScan Commercial and MarketScan Medicare Supplemental databases. Women had a metastatic disease diagnosis and newly initiated treatment with IV paclitaxel/nab-paclitaxel (first administration date was considered the index date), and continuous enrollment for at least 12 months prior to and at least 3 months following the index date. Treatment discontinuation, dose reductions, toxicities, and health care utilization and costs per patient per month (PPPM) were assessed over the full follow-up and the index line of IV paclitaxel/nab-paclitaxel therapy (Index LOT).

The sample included 8890 women aged 54.6 (±10.9) yeacontain costs.
Many mBC patients initiating IV paclitaxel/nab-paclitaxel experienced dose reductions, toxicities, and/or early discontinuation of the Index LOT, which may limit treatment effectiveness. More tolerable treatments with reduced dosing complexity could improve mBC treatment and help contain costs.
Typically, a community-based specialty practice is prepared for a limited public health crisis that is driven by a natural disaster or a localized environment event. This article describes the unexpected impact that the coronavirus disease 2019 (COVID-19) pandemic has had on community-based specialty practices across the United States, especially oncology practices.

We conducted an electronic national survey of community-based specialty practice administrators to determine the impact of COVID-19 on their practices and their ability to manage through a global pandemic. The 22-question survey focused on an initial observation period of March 15, 2020, to May 15, 2020, compared with a second period of May 16, 2020, to August 15, 2020.

Oncology practices accounted for 46% of the 155 specialty practices that participated in the survey. Overall, 57% of respondents saw at least a 30% decline in total patient volume and/or financial impact during the initial observation period, compared with a 38% decline for the oncology practices. More than 70% of all practices experienced improvement after May 15, 2020, with at least 60% improving regardless of specialty. The initial decline was primarily driven by declines in new patient volume and procedures. Approximately 62% of practices anticipate a moderate-to-significant impact on patient outcomes over the next 12 months. link3 The impact expected was slightly higher in retina and ophthalmology practices than oncology.

Although unexpectedly impacted in delivering care for their patients, specialty practices generally and oncology practices especially have been resilient by leveraging federal funds and adopting operational enhancements.
