What factors influence dyadic synchrony? A systematic review of the literature on predictors of mother–infant dyadic processes of shared behavior and affect
Authors: Golds Lisa , Gillespie‐Smith Karri , Nimbley Emy , MacBeth Angus 
Published: August 2022

AbstractDyadic behavioral synchrony is a complex interactional process that takes place between the mother and her infant. In the first year of life, when the infant is prelinguistic, processes such as synchrony enable the dyad to communicate through shared behavior and affect. To date, no systematic review has been carried out to understand the risk and protective factors that influence behavioral synchrony in the mother–infant dyad. The aim of this review was to identify and evaluate the factors that influence behavioral synchrony in the mother–infant dyad, when the infant is between 3 and 9 months old. Key electronic databases were searched between 1970 and April 2021, and 28 eligible studies were identified for review. As the results were largely heterogeneous, four subgroups of factors were identified: (i) infant demographics, (ii) physiological factors, (iii) maternal mental health, and (iv) miscellaneous factors. Identified risk factors and covariates suggest that social determinants of health, underpinned by biological factors, play a large role in influencing behavioral synchrony within the dyad. Implications for the need to identify additional risk and protective factors, as well as design support for at‐risk families are discussed.

Published: August 2022

AbstractBACKGROUNDThe availability of highly active, low‐cost and stable oxygen reduction reaction (ORR) electrocatalysts remains a barrier to the development of energy techniques. This study presents molybdenum trioxide/reduced graphene oxide (MoO3/rGO) composite as an effective electrocatalytic material for ORR.RESULTSThe nanosized MoO3 particles loaded on rGO as an efficient ORR catalyst was prepared via a two‐step method. The MoO3(0.1)/rGO nanocomposite showed the highest content of Mo6+ and rGO carbon among rGO and MoO3/rGO. The MoO3(0.1)/rGO showed the highest limiting current density of −3.04 mA cm−2 at 0.2 V versus reversible hydrogen electrode, which was comparable to the commercial 10% Pt/C in the present work. The electron transfer number of 2.74 on MoO3(0.1)/rGO indicated ORR selectivity towards the four‐electron pathway was not very high. The electrochemical active surface area of the MoO3(0.1)/rGO nanocomposite was 9.94 cm2, which was about twice the commercial 10% Pt/C. The small Tafel slope of 57.56 mV dec−1 confirms the high ORR activity of the MoO3(0.1)/rGO catalyst. The MoO3(0.1)/rGO also showed good stability under alkaline conditions and better methanol tolerance compared to the commercial 10% Pt/C.CONCLUSIONThe increased activity of the MoO3(0.1)/rGO composite may be attributed to the higher content of Mo6+ and rGO carbon in the catalyst. Performance of the catalysts may be further improved by optimizing the experimental conditions. The synthesized MoO3/rGO composite is a potential alternative electrocatalyst for ORR. © 2022 Society of Chemical Industry (SCI).

要旨Nonsteroidal anti–inflammatory drugs（NSAIDs）不耐症は種々のNSAIDsの使用でアレルギー様症状を来す疾患で，単一の薬剤から生じるNSAIDアレルギーとは区別される。アセトアミノフェンを含めたすべてのCOX–1阻害薬に対して過敏反応を示すのが特徴である。単一の薬剤を回避すればよいアレルギーと異なるため，その診断は発作予防の観点から重要である。症例は23歳の女性。交通事故による左橈骨遠位端骨折，右脛骨骨折，右腓骨骨折を受傷して入院し，二期的に手術を施行した。初回の手術後にロキソプロフェンを使用した際，全身の膨疹と紅斑，および咽頭の掻痒感が出現し，薬剤アレルギーとして対応した。2回目の手術の周術期ではロキソプロフェンの使用を回避したが，翌日に掻痒感を伴う膨疹と呼吸困難が出現したためアナフィラキシーとして対応した。その後，アセトアミノフェン投与後にもアレルギー様症状が出現したため，被疑薬のプリックテストを施行したがすべて陰性で，I型アレルギー関与の可能性は低いと考えられた。内服テストを施行した結果，アセトアミノフェンの少量内服で発疹と掻痒感が生じたためNSAIDs不耐症と診断した。複数の鎮痛薬に対してアナフィラキシー症状を呈する患者ではNSAIDs不耐症を鑑別に挙げるべきである。

要旨症例は59歳の男性。他院にて下部消化管内視鏡検査目的にポリエチレングリコールを含む経口腸管洗浄剤を内服した。内服後に全身掻痒感，血圧と酸素飽和度の低下を認め，アナフィラキシーショックと判断され，アドレナリン0.3mg筋注とメチルプレドニゾロン500mgの静注の後に，当院高度救命救急センターに転院搬送された。来院時は意識清明で，血圧170/114mmHg，脈拍数146/minであったが，来院23分後に突然心室細動から心停止となった。直ちに心配蘇生を行い，17分後に自己心拍が再開した。十二誘導心電図検査でV1–3誘導にQ波，V4–6誘導でST低下を認めたため，緊急に冠動脈造影検査となった。冠動脈造影では左前下行枝に有意狭窄を認め，光干渉断層計検査で左前下行枝に留置されているステント内に血栓像が認められたことから，Kounis症候群type 3と診断した。経皮的冠動脈インターベンションにて冠血行再建術を施行し，ステントを拡張した。以後，経過良好につき第9病日に独歩にて退院となった。ポリエチレングリコールによるアナフィラキシーは稀であるが，冠動脈ステント留置歴がある場合にはKounis症候群type 3を生じ心停止に至ることもあることから，使用の際には注意を要する。
Assessing homogeneity of land surface air temperature observations using sparse‐input reanalyses

Published: August 2022

AbstractState‐of‐the‐art homogenisation approaches for any test site rely upon the availability of a sufficient number of neighbouring sites with similar climatic conditions and a sufficient quantity of overlapping measurements. These conditions are not always met, particularly in poorly sampled regions and epochs. Modern sparse‐input reanalysis products which are constrained by observed sea surface temperatures, sea‐ice and surface pressure observations, continue to improve, offering independently produced surface temperature estimates back to the early 19th century. This study undertakes an exploratory analysis on the applicability of sparse‐input reanalysis to identify breakpoints in available basic station data. Adjustments are then applied using a variety of reanalysis and neighbour‐based approaches to produce four distinct estimates. The methodological independence of the approach may offer valuable insights into historical data quality issues. The resulting estimates are compared to Global Historical Climatology Network version 4 (GHCNMv4) at various aggregations. Comparisons are also made with five existing global land surface monthly time series. We find a lower rate of long‐term warming which principally arises in differences in estimated behaviour prior to the early 20th century. Differences depend upon the exact pair of estimates, varying between 15 and 40% for changes from 1850–1900 to 2005–2014. Differences are much smaller for metrics starting after 1900 and negligible after 1950. Initial efforts at quantifying parametric uncertainty suggest this would be substantial and may lead to overlap between these new estimates and existing estimates. Further work would be required to use these data products in an operational context. This would include better understanding the reasons for apparent early period divergence including the impact of spatial infilling choices, quantification of parametric uncertainty, and a means to update the product post‐2015 when the NOAA‐CIRES‐DOE 20CRv3 sparse input reanalysis product, upon which they are based, presently ceases.
Electrochemical characterization of a novel multicomponent Al75Mg5Li10Zn5Cu5 low entropy alloy in different pH environments

Published: August 2022

AbstractThe corrosion behavior and microstructure of a novel multicomponent Al75Mg5Li10Zn5Cu5 low entropy alloy (Al LEA) were investigated in different Cl− ion concentrations of acidic (HCl), neutral (NaCl), and alkaline (NaOH) media. The study was performed by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. The surface morphologies and chemical composition were examined by using a scanning electron microscope with energy‐dispersive X‐ray spectroscopy. The results indicated that with the increase of the Cl− ion concentrations, the degradation rate with more pits and cracks was observed in both acidic and neutral media. This is due to the breakdown of Al(OH)3/Al2O3 passive layer. In an alkaline medium, increasing of pH value from pH 8 to pH 12, there was a slight increment in corrosion rate (CR). However, the corrosion trend was not witnessed on alloy surfaces because of the formation of Mg32(Al, Zn)49 and AlCu phases, which are more stable than α‐Al. The order of Al‐LEA CR is found to be HCl > NaCl > NaOH. The results obtained from the polarization and EIS were in good agreement with each other.

AbstractPurposeThe purpose of this investigation is to evaluate the use of a probe‐format graphite calorimeter, Aerrow, as an absolute and relative dosimeter of high‐energy pulse dose rate (UHPDR) electron beams for in‐water reference and depth–dose‐type measurements, respectively.MethodsIn this paper, the calorimeter system is used to investigate the potential influence of dose per pulses delivered up to 5.6 Gy, the number of pulses delivered per measurement, and its potential for relative measurement (depth–dose curve measurement). The calorimeter system is directly compared against an Advanced Markus ion chamber. The finite element method was used to calculate heat transfer corrections along the percentage depth dose of a 20‐MeV electron beam. Monte Carlo–calculated dose conversion factors necessary to calculate absorbed dose‐to‐water at a point from the measured dose‐to‐graphite are also presented.ResultsThe comparison of Aerrow against a fully calibrated Advanced Markus chamber, corrected for the saturation effect, has shown consistent results in terms of dose‐to‐water determination. The measured reference depth is within 0.5 mm from the expected value from Monte Carlo simulation. The relative standard uncertainty estimated for Aerrow was 1.06%, which is larger compared to alanine dosimetry (McEwen et al. https://doi.org/10.1088/0026‐1394/52/2/272) but has the advantage of being a real‐time detector.ConclusionIn this investigation, it was demonstrated that the Aerrow probe–type graphite calorimeter can be used for relative and absolute dosimetries in water in an UHPDR electron beam. To the author's knowledge, this is the first reported use of an absorbed dose calorimeter for an in‐water percentage depth–dose curve measurement. The use of the Aerrow in quasi‐adiabatic mode has greatly simplified the signal readout, compared to isothermal mode, as the resistance was directly measured with a high‐stability digital multimeter.
Technical note: rtdsm—An open‐source software for radiotherapy dose‐surface map generation and analysis
Authors: Patrick Haley M. , Kildea John 
Published: August 2022

AbstractBackgroundDose‐outcome studies in radiation oncology have historically excluded spatial information due to dose‐volume histograms being the most dominant source of dosimetric information. In recent years, dose‐surface maps (DSMs) have become increasingly popular for characterization of spatial dose distributions and identification of radiosensitive subregions for hollow organs. However, methodological variations and lack of open‐source, publicly offered code‐sharing between research groups have limited reproducibility and wider adoption.PurposeThis paper presents rtdsm, an open‐source software for DSM calculation with the intent to improve the reproducibility of and the access to DSM‐based research in medical physics and radiation oncology.MethodsA literature review was conducted to identify essential functionalities and prevailing calculation approaches to guide development. The described software has been designed to calculate DSMs from DICOM data with a high degree of user customizability and to facilitate DSM feature analysis. Core functionalities include DSM calculation, equivalent dose conversions, common DSM feature extraction, and simple DSM accumulation.ResultsA number of use cases were used to qualitatively and quantitatively demonstrate the use and usefulness of rtdsm. Specifically, two DSM slicing methods, planar and noncoplanar, were implemented and tested, and the effects of method choice on output DSMs were demonstrated. An example comparison of DSMs from two different treatments was used to highlight the use cases of various built‐in analysis functions for equivalent dose conversion and DSM feature extraction.ConclusionsWe developed and implemented rtdsm as a standalone software that provides all essential functionalities required to perform a DSM‐based study. It has been made freely accessible under an open‐source license on Github to encourage collaboration and community use.

AbstractBackgroundIn tuberculosis (TB) treatment, adverse drug reactions (ADRs) can interrupt treatment and decrease the quality of life (QoL). We aimed to prospectively investigate the incidence of ADRs to first‐line anti‐TB drugs and related outcomes and QoL.MethodsAdult patients with TB who had been treated with first‐line anti‐TB drugs in five Korean hospitals were enrolled. ADR questionnaire surveys and blood tests were performed four times serially, and QoL was assessed on the fourth TB treatment week (±2 weeks).ResultsOf 410 enrolled patients with TB (males, 62%; mean age, 52.1 ± 18.1 years [those aged ≥65 years, 26.6%]), 67.8% experienced any ADRs (≥ grade 2) to TB drugs. The most common ADR was fatigue (53.2%), followed by itching (42.7%) and anorexia (41.7%). Older adult patients experienced relatively more ADRs, including anorexia, dyspepsia, rash, dizziness, anemia, abnormal hepatic/renal function tests, and increased uric acid levels (p < 0.05). Treatment regimens changed for 9.5% of patients owing to ADRs to anti‐TB drugs. Patients with any ADRs and older adult patients had significantly lower QoL than their counterparts (p < 0.05). Old age (odds ratio [OR], 1.02) and being male (OR 2.65) were independently associated with ADRs, whereas active smoking (OR 4.73) and a relatively long treatment phase (OR 5.13) were independently associated with hepatotoxicity.ConclusionADRs to first‐line anti‐TB drugs were common and related to relatively low QoL, especially among older adults. Although 9.5% of patients had ADR‐related regimen changes, most patients with ADRs completed treatments successfully.

Published: August 2022

AbstractPoly(vinyl alcohol) (PVA) hydrogels have shown potential applications in bionic articular cartilage due to their tissue‐like viscoelasticity, good biocompatibility and low friction. However, their lack of adequate mechanical properties is a key obstacle for PVA hydrogels to replace natural cartilage. In this study, poly(ethylene glycol) (PEG) and glycerol were introduced into PVA, and a PVA/PEG–glycerol composite hydrogel was synthesized using a mixing physical crosslinking method. The mechanical properties, hydrophilicity and tribological behavior of the PVA/PEG–glycerol hydrogel were investigated by changing the concentration of glycerol in PEG. The results showed that the tensile strength of the hydrogel reached 26.6 MPa at 270% elongation at break with 20 wt% of glycerol plasticizer, which satisfied the demand of natural cartilage. In addition, the excellent hydrophilicity of glycerol provides good lubricating properties for the composite gel under dry friction. Meanwhile, self‐healing and cellular immunity assays demonstrated that the composite gel could have good self‐healing ability and excellent biocompatibility even in the absence of external stimuli. This study provides a new candidate material for the design of articular cartilage, which has the potential to facilitate advances in artificial joint cartilage repair. © 2022 Society of Industrial Chemistry.

Societal Impact StatementHistoric North American apple (Malus domestica) orchards that thrived in the late 19th and early 20th centuries, with cultivar compositions unlike today's orchards, are vanishing. There are several reasons for this loss: tree aging, cost of tree maintenance, and urbanization. Many groups have collected local knowledge regarding the history and horticulture of apples using both phenotypic and genotypic identification methods. Some of these groups have joined with scientists to form the collaborative “Historic Fruit Tree Working Group of North America” to facilitate the conservation of heirloom apple cultivars in North America through documentation, identification, collaboration, and education.

AbstractLow‐cost and high efficiency P25 (nanoparticles TiO2)/blue anoxic tungsten oxide (WO3‐x) heterostructure was successfully constructed by one‐step low‐temperature hydrothermal method. Moreover, sodium tungstate dihydrate (Na2WO4 ⋅ 2H2O) instead of tungsten hexachloride (WCl6) further lowers cost and facilitates preparation. P25/blue WO3‐x heterostructure, rich in oxygen vacancies with typical blue color, exhibits improved performances in both electrocatalysis and photocatalysis. Compared with the pure P25 and blue WO3‐x, the exchange current density of P25/blue WO3‐x was increased by 6 times and 22 times, respectively. P25/blue WO3‐x showed the lowest over potential and relatively small Tafel slope. Also, the degradation efficiency of P25/blue WO3‐x was much higher than other samples. The mechanism of photocatalysis was investigated. The trapping experiments confirmed h+ and ⋅OH were the main active species in photocatalytic reaction. The matched energy levels and built‐in electric field of heterostructure interface can inhibit the recombination of photogenerated electron‐hole pairs to enhance the photodegrading efficiency. The simple low‐cost method is a beneficial attempt to prepare excellent bi‐functional materials with electrocatalytic and photocatalytic properties for practical application prospect in energy shortage and environmental pollution.
Constructing CNT@NiCo Texture Anchoring Pt Nanoparticle Catalyst for Highly Efficient Methanol Electrocatalytic Oxidation**

Published: August 2022

AbstractIn this paper, CNT@NiCo‐s (Carbon nanotube@NiCo‐sheet) and CNT@NiCo‐g (Carbon nanotube@NiCo‐granular) composite carriers were prepared by two special methods. After that, the Pt nanoparticles were loaded on the surface of these composite supports by the sodium borohydride (NaBH4) reduction method to obtain Pt/CNT@NiCo‐s and Pt/CNT@NiCo‐g. Cyclic voltammeter and chronoamperometry were used to determine the methanol oxidation activity and durability of these catalysts. The results show that the doping of the granular NiCo alloy carrier effectively improves the activity and anti‐toxicity of the Pt/CNT catalyst for the methanol electrocatalytic oxidation reaction (MOR). It confirmed that the advantages of Pt/CNT@NiCo‐g catalyst were attributed to a large specific surface area, abundant defects, and abundant oxides and hydroxides, which jointly promoted the electrocatalytic oxidation of methanol.

AbstractHydrogen production through water electrolysis using renewable energy is expected to be one approach to solving current energy problems. The present report describes the development of a hemispherical cavity cobalt (Co) electrocatalyst with uniform pores with sizes of several hundred nanometers on the surface via electrodeposition on an indium tin oxide (ITO) substrate in a carbonate electrolyte solution using a polystyrene particle template. Catalytic activity measurements indicated that the cavity Co catalyst generated a greater oxygen evolution current compared to the flat Co catalyst. To investigate the electronic state and local structure, operando Co K‐edge XAFS measurements of the cavity Co catalyst were obtained under working conditions, which showed that Co species in the catalyst changed to one with a higher oxidation number while maintaining the local structure of CoOOH (CoO6). These results clarified that the cavity Co catalyst efficiently promoted water splitting through the uniform nanoscale pores with high oxidation Co in the CoOOH structure.
