Sodium-ion batteries (SIBs) have been considered as one of the most promising secondary battery techniques for large-scale energy storage applications. However, developing appropriate electrode materials that can satisfy the demands of long-term cycling and high energy/power capabilities remains a challenge. Herein, a fluorine modulation strategy is reported that can trigger highly active exposed crystal facets in anatase TiO2-x Fx , while simultaneously inducing improved electron transfer and Na+ diffusion via lattice regulation. When tested in SIBs, the optimized fluorine doped TiO2-x Fx nanocrystals exhibit a high reversible capacity of 275 mA h g-1 at 0.05 A g-1 , outstanding rate capability (delivering 129 mA h g-1 at 10 A g-1 ), and remarkable cycling stability with 91% capacity retained after 6000 cycles at 2 A g-1 . Importantly, the optimized TiO2-x Fx nanocrystals are dominated by pseudocapacitive Na+ storage, which can be attributed to the fluorine induced surface and lattice regulation, enabling ultrafast electrode kinetics.Stretchable conductors capable of precise micropatterning are imperative for applications in various wearable technologies. Metallic nanoparticles with low aspect ratios and miniscule sizes are preferred over metallic nanowires or nanoflakes for such applications. However, nanoparticles tend to lose mutual contact during stretching. Therefore, they are rarely used alone in stretchable conductors. In this study, electronic inks comprising silver nanoparticles (AgNPs) for the high-resolution printing of stretchable conductors are reported. AgNPs are synthesized using aqueous polyurethane micelles, which are subsequently disentangled into polymeric chains in isopropanol to stabilize the inks. The ink rheology can be arbitrarily tuned to allow direct-write printing with a minimum feature width of 3 µm. Owing to the absence of extra surfactants, direct drying of such inks at room temperature provides the stretchable conductors with an initial conductivity of 8846 S cm-1 and conductivity of 1305 S cm-1 at 100% strain. This enhanced performance is attributed to the conductive percolations through assemblies of AgNPs adapting to the strain and is equivalent to those of stretchable conductors filled with Ag nanowires or flakes. These inks are promising for the scalable fabrication of highly integrated stretchable electronics.Argentina is a large country in which important asymmetries exist in the knowledge and management of psoriasis. For this reason, in 2015 we launched Project ECHO Psoriasis, a telementoring strategy for dermatologists aimed at providing best medical practices in this population. The main objective of this study was to explore the reasons why the physicians participating in Project ECHO Psoriasis Argentina sought remote assistance. Cross-sectional study of the consultations made by dermatologists to the panel of experts. 213 consultations, which involved 158 patients in 60 teleclinics, were analyzed. The most frequent reasons for consultation were to implement changes in ongoing treatment, to support the treating physician approach to the patient, and to choose a de novo treatment, which were observed in 63 (39.9%), 47 (29.7%) and 46 (29.1%) consultations, respectively. The experts suggested modifying the approach to the patients in two thirds of the consultations (69.6%; 95% CI 61.8-76.7). Complete and partial compliance with the suggestions were observed in 66.4% (95% CI 56.7-75.1) and in 4.5% (95% CI 1.5-10.3), respectively. The main barriers identified were adherence by the patients and health services access issues. Telementoring for psoriasis is useful in reducing asymmetries in knowledge between dermatologists and ensuring access to the best clinical practices.

Guidelines recommend inviting family members of intensive care unit (ICU) patients to rounds. We aimed to create a toolkit to support family participation in ICU bedside rounds, based upon evidence from research and in collaboration with ICU family member representatives and healthcare providers.

Ethnographic observations of rounds and interviews and focus groups with family members and ICU healthcare providers were analyzed for key themes, barriers and facilitators of participation, and suggestions. A full day workshop with family representatives and providers (physicians, nurses, social workers, and unit managers) from a diverse range of adult ICUs in Western Canada, including several community ICUs and a majority of large, urban ICUs enabled the collaborative development of key toolkit elements.

We have developed an evidence-informed approach to patient-and-family-centered rounds that highlights the importance of six key elements foundational to patient and family centered rounds Invitation, Orientation, Engagement, Summary, Questions, and Communication Follow-Up. We describe strategies, techniques, and templates to optimize these elements and interactions so that communication is more meaningful, and to facilitate the ability of family members to adopt a meaningful role as contributing members of the care team.

There is consensus on general strategies for facilitating family participation in rounds and meaningful communication between family and the healthcare team during rounds as an important element of the continuum of communication in the ICU. The incorporation of these elements should be standardized, though tailored to user needs.

Intraoral defects after tumor resection are often reconstructed with free tissue transfer. However, in patients who are not good candidates for free tissue transfer, regional flaps based on the superficial temporal artery can be utilized. The authors present our technique to reconstruct intraoral defects with the superficial temporal artery perforator (STAP) flap and early outcomes.

Five patients underwent STAP flaps for defects including the hard palate, buccal sulcus, floor of mouth, and retromolar trigone between 2017 and 2019. selleck inhibitor The mean defect size was 5.6 × 3.4 cm

(3 × 3 cm

- 7 × 4 cm

). The mean age was 74 (57-88) and all patients had recurrent cancer. External Doppler, indocyanine green laser angiography, and FLIR thermal imaging were used intra-operatively to identify the best perforators and plan for flap design.

The mean flap size was 7.6 × 3.5 cm

(6 × 3 cm

- 10 × 5 cm

). Four flaps were based off of the posterior branch of the STA, while the fifth was based off of the anterior branch.
