Plasmonic nanomaterials coupled with catalytically active surfaces can provide unique opportunities for various catalysis applications, where surface plasmons produced upon proper light excitation can be adopted to drive and/or facilitate various chemical reactions. A brief introduction to the localized surface plasmon resonance and recent design and fabrication of highly efficient plasmonic nanostructures, including plasmonic metal nanostructures and metal/semiconductor heterostructures is given. Taking advantage of these plasmonic nanostructures, the following highlights summarize recent advances in plasmon-driven photochemical reactions (coupling reactions, O2 dissociation and oxidation reactions, H2 dissociation and hydrogenation reactions, N2 fixation and NH3 decomposition, and CO2 reduction) and plasmon-enhanced electrocatalytic reactions (hydrogen evolution reaction, oxygen reduction reaction, oxygen evolution reaction, alcohol oxidation reaction, and CO2 reduction). Theoretical and experimental approaches for understanding the underlying mechanism of surface plasmon are discussed. A proper discussion and perspective of the remaining challenges and future opportunities for plasmonic nanomaterials and plasmon-related chemistry in the field of energy conversion and storage is given in conclusion. © 2020 WILEY-VCH Verlag GmbH & Co.

OBJECTIVES This cross-sectional cohort study investigated associations between cam morphology presence, size and duration and symptoms and ROM. METHODS Academy male football players (n = 49, 17-24 years) were included. Standardized antero-posterior pelvic and frog-leg lateral radiographs were obtained at baseline, 2.5- and 5-year follow-up. The femoral head-neck junction was quantified by Visual score. Cam morphology (flattening or prominence), large cam (prominence). Alpha angle. Cam morphology (≥60°), large cam (≥78°). Cam morphology duration was defined as long (first present at baseline) or short (only from 2.5- to 5-year follow-up). Current symptoms at 5-year follow-up were assessed using a hip and groin pain question and by the "Hip and Groin Outcome Score" (HAGOS). HAGOS scores were categorized into most symptoms (≥2 domains in lowest interquartile range [IQR]), least symptoms (≥2 domains in highest IQR). Hip ROM was measured by goniometry at 5-year follow-up. RESULTS Large cam morphology based on visual score was associated with hip and groin pain (23.8% vs. 7.1%, OR 3.17, CI [1.15-8.70], P = .026), but not with HAGOS scores. Cam morphology presence, size, and duration were associated with limited flexion of around 6° and/or 3° to 6° for internal rotation. CONCLUSION Cam morphology presence, size, and duration were associated with limited hip flexion and/or internal rotation, but differences might not exceed the minimal clinical important difference. Whether cam morphology results in symptoms is uncertain. © 2020 The Authors.

A dynamic light scattering (DLS), transmission electron microscopy (TEM), and inductively coupled plasma mass spectrometer (ICP-MS) were used to evaluate the suspended ENMs in the products. Direct-reading instruments, TEM, and ICP-MS were used to characterize the properties of aerosolized ENMs. The aerosolized organic compounds with ENMs were assumed to be vaporized for a short time after spraying. The median diameter of ENMs in product solutions measured by DLS was about 200-350 nm, while individual particle was confirmed from 3 to 50 nm by TEM. The size of aerosolized ENMs was ranged from 7 to 44 nm, and their aggregates were about 100-1000 nm in near distance. Some inorganic substances including raw nanomaterials were also found in the aerosol. The particles released from the propellant sprays were identified in far distance, while they were not found in far distance when pump sprays were used. The number concentration from the propellant sprays increased up to 6000 particles/cm3 /g at near distance and dispersed to far distance, while the most of droplets emitted from pump sprays were settled down near sprayer's location. We found other metals besides labeled ENMs are included in each product and the characteristics of the particles are different when they are sprayed. © 2020 John Wiley & Sons A/S.

Patients who initiated HD aged ≥70 years and received a mature AVF creation were included retrospectively. Echocardiographic parameters measured within 1 week before AVF creation were acquired. The observational period for each patient was from the point of AVF creation to the last time of follow-up unless AVF abandonment or death occurred. learn more Kaplan-Meier and Cox proportional hazard regression analyses were conducted. A total of 82 elderly Chinese HD patients with mature radiocephalic AVF (RCAVF) and EF ≥50% were analyzed. During the median study period of 26.8 (12-40) months, 42 (51.2%) experienced RCAVF dysfunction and 34 (41.5%) progressed to abandonment. Primary and cumulative patencies at 6, 12, 24, and 36 months were 81%, 73%, 48%, 38%, and 84%, 81%, 68%, 55%, respectively. Left ventricle end-diastolic volume (LVEDV) ≤103.5 mL (HR = 2.5, P = .019) and the right side of RCAVF (HR = 3.59, P = .003) significantly predicted RCAVF dysfunction. The main pulmonary artery internal diameter (MPAID) ≤21.5 mm (HR = 4.3, P = .001) as well as the right side (HR = 2.95, P = .047) were the independent predictors for RCAVF abandonment. In conclusion, LVEDV, MPAID assessed by echocardiography and the right side of RCAVF, showed significant predictive implications for the outcomes of RCAVF. Disparities among nationalities in the areas of utilization and patency of AVFs necessitate additional studies. © 2020 Wiley Periodicals, Inc.BACKGROUND Convergence insufficiency may be treated by visual exercises designed to increase convergence while maintaining single, clear, binocular vision. However, compliance with treatment is problematic, as patients often cease treatment when symptoms start to improve and before treatment is complete. The purpose of the present study was to assess the feasibility of using gamification of vision training to (a) treat convergence insufficiency; and (b) improve compliance to treatment in comparison to a conventional treatment over a six-week treatment period. METHODS Two interventions, anaglyphs and a virtual reality game of Snakes, were evaluated for their effectiveness in treating adults with convergence insufficiency. The prescribed training regimen was 20 minutes, three times per week for six weeks. Vision was assessed before and after the treatment period. Participants also filled in the Core Elements of the Gaming Experience Questionnaire to gauge impact of game design on compliance. RESULTS Eighteen participants (mean age 20.8 ± 1.8 years) met the inclusion criteria for convergence insufficiency and nine participants were randomly assigned to each intervention. Repeated measures analysis of variance showed a significant effect of visit for near point of convergence (F1,16 = 38.32, p  less then  0.0001), near positive fusional reserves break (F1,16 = 21.94, p  less then  0.0001) and recovery (F1,16 = 26.87, p  less then  0.0001), but not of intervention type. Total time played was significantly longer for the virtual reality Snake Game than the anaglyph intervention (p  less then  0.0001), which translated to mean compliance of 82 per cent and 51 per cent respectively. CONCLUSION Gamification of vision training in a virtual reality environment is feasible and associated with increased compliance, hence may be a useful strategy to treat convergence insufficiency. © 2020 Optometry Australia.Influenza transmission occurs through the air, but the relative importance of small droplets, or aerosols, in influenza transmission especially within healthcare facilities remains uncertain. Detections of influenza virus in aerosols in cough and exhaled breath from infected patients, and from the air in outpatient or inpatient healthcare facilities have been studied, but most studies were done in adults with very few data involving children. We aimed to assess the potential of influenza transmission via aerosols in pediatric patient rooms. Two-stage cyclone (NIOSH) air samplers were used to collect the air in 5-bed pediatric patient rooms with patients with PCR-confirmed influenza. Influenza A virus RNA was recovered in 15/19 (79%) air sampling occasions, in all size fractions (>4µm, 1-4µm and less then 1µm), and significantly less for influenza B virus (2/10 occasions, 20%). We estimated a ventilation rate of 1.46 ACH in a similar but unoccupied 5-bed patient room. High quantities of influenza A virus RNA detected in the air in pediatric patient rooms suggests other individuals in paediatric patient rooms including other patients, visitors, caretakers and healthcare workers could be exposed to influenza A virus while caring for infected children.

Women choose this option for many reasons other than reducing their risk of future cancer, including symmetry, reasons related to breast reconstruction and attempting to manage fear of recurrence. This systematic review evaluated patient-reported quality of life outcomes following CPM. METHODS A literature search of MEDLINE, PubMed and PsycINFO was performed to February 2019. Abstracts and full-text articles were assessed for eligibility according to pre-determined criteria. Data were extracted into evidence tables for analysis. RESULTS A total of 19 articles met eligibility criteria and were included in analysis. These included patient-reported data from 6088 women undergoing CPM. They reported high levels of satisfaction with the decision for surgery, low levels of decisional regret and high satisfaction with cosmesis and reconstruction. Breast-specific and general quality of life was high overall but was even better in women choosing breast reconstruction after surgery. Fear of cancer recurrence was high after CPM. Depression, distress and a negative impact on body image were evident; however, levels were high in both CPM and non-CPM groups. CONCLUSIONS This study provides information that can be used by surgeons and psychologists when counselling women about the potential benefits and harms of CPM. This process must include discussion about the trade-offs such as body image issues and ongoing fear of recurrence in addition to the positive aspect of cancer risk reduction. Women are unlikely to regret their decision for CPM. © 2020 John Wiley & Sons, Ltd.
