Authors: Rodrigues Cláudia , Claro Rui 
Published: January 2021

Case:
This is a case of a 28-year-old CrossFit athlete who was observed at the emergency department after a competition with acute right shoulder pain. After investigation, she claimed of some posterior shoulder tightness for the past month, without any trauma associated. After the imaging study, we diagnosed a scapula stress fracture. After 8 weeks of rest, she was pain free and returned to sports.

Conclusion:
Stress fracture of the scapula should be considered in the differential diagnosis of shoulder pain in overhead activities athletes. This case illustrates an excellent prognosis with conservative treatment and the potencial for full return to sports.

Published: January 2021

Case:
This report describes a case of pediatric femoral head chondroblastoma, which was initially treated by minimally invasive curettage. At the 18-month follow-up, a subsequent osteochondral defect occurred, which was treated with a partial articular resurfacing system. At 5.5 years follow-up, he was symptom-free with minor degenerative x-ray changes.

Conclusion:
We describe a technique of focal anatomic hip resurfacing using the HemiCAP system in a pediatric chondroblastoma patient who presented with an osteochondral defect after primary curettage. This approach yielded good short-term to midterm results and is a potential alternative to total hip arthroplasty in young patients.

Abstract
Background: Numerous studies have confirmed the association of ambient temperature and air pollution with a higher risk of morbidities, yet few have addressed their effect on the ocular system. The purpose of this study was to assess the association between temperature, air pollution, and emergency room visits for conjunctivitis.Methods: In this case-crossover study, the records of all emergency room visits to Soroka University Medical Center (SUMC) from 2009 to 2014 were reviewed for patients with conjunctivitis. Daily exposure to fine and coarse particulate matter and temperature were determined by a hybrid model involving satellite sensors.Results: 6001 patients were diagnosed with conjunctivitis in the SUMC emergency room. We discovered a positive association between temperature increments and incidence of conjunctivitis. The strongest effect was found during summer and autumn, with an immediate (lag0) incidence increase of 8.1% for each 1 °C increase in temperature (OR 1.088 95%CI 1.046;1.132) between 24 and 28 °C in the summer and 7.2% for each 1 °C increase in temperature (OR 1.072 95%CI 1.036;1.108) between 13 and 23 °C in the autumn. There was no statistically significant association between fine and coarse particulate matter and conjunctivitis incidence.Conclusion: Temperature increases during summer and autumn are significantly associated with an increased risk of conjunctivitis. Conjunctivitis is not associated with non-anthropogenic air pollution. These findings may help community clinics and hospital emergency rooms better predict conjunctivitis cases and will hopefully lead to improved prevention efforts that will lower the financial burden on both the individual and the public.

Published: January 2021

Abstract
Background: Compared to their white counterparts, Latina breast cancer survivors experience poorer quality of care and worse health-related quality of life. Limited English proficiency (LEP) and patient engagement in cancer care could help explain these disparities. We assessed associations between LEP status and difficulty engaging with physicians, with self-reported quality of breast cancer care and health-related quality of life (physical and emotional well-being) among rural and urban Latina breast cancer survivors. Methods: Analyses used cross-sectional baseline survey data from two studies that tested a stress management program among rural and urban Latina breast cancer survivors in California. Medical information was collected through medical records review. Linear regression models examined bivariate and multivariable associations of LEP status (yes or no), difficulty engaging with doctors (asking questions and participating in treatment decisions) (1-4; higher score=greater difficulty), and rural versus urban site, with three outcomes: 1) quality of breast cancer care and information; 2) physical well-being; and 3) and emotional well-being, controlling for demographic and medical factors. Results: The total sample included 304 women (151 from urban and 153 from rural sites). Mean age was 52.7 years (SD 10.9). Most were limited English proficient (84.5%) and had less than a high school education (67.8%). Difficulty engaging with doctors was inversely associated with patient ratings of quality of breast cancer care and information (B = - 0.190, p=0.014), emotional well-being (B = -1.866, p <0.0001), and physical well-being (B = -1.272, p = 0.002), controlling for demographic and treatment factors. LEP (vs. not; B = 1.987, p = 0.040) was independently associated with physical well-being only. Rural/urban status was not related independently to any outcome.Conclusions: Rural and urban Latina breast cancer survivors who report greater difficulty engaging with physicians experienced worse quality of breast cancer care and health-related quality of life. Promoting greater engagement of Latina breast cancer survivors in cancer care and providing medical interpreters when needed could improve patient outcomes among this vulnerable group.Trial registration: http://www.ClinicalTrials.gov identifier NCT02931552 and NCT01383174.

Kilometer-scale structure on the core-mantle boundary at the source of the Hawaiian mantle plume
Authors: Li Zhi , Leng Kuangdai , Jenkins Jennifer , Cottaar Sanne 
Published: January 2021

Abstract
The lowermost mantle right above the core-mantle boundary shows a complex and heterogeneous landscape containing multiple poorly understood seismic features visible across a wide range of length scales. The smallest, but most extreme, heterogeneities yet observed are 'Ultra-Low Velocity Zones' (ULVZ), several of which have recently been linked to the base of mantle plumes. We exploit seismic shear waves that diffract along the core-mantle boundary to provide new insight into these enigmatic structures. We demonstrate that these waves have a strong frequency-dependent sensitivity to structure at different length scales above the core-mantle boundary, similar to the dispersive characteristics of surface waves. We measure a rare core-diffracted signal refracted by a ULVZ at the base of the Hawaiian mantle plume at unprecedented high frequencies. This signal shows remarkably longer time delays compared to lower frequencies, indicating extreme internal variability within the Hawaiian ULVZ. Utilizing the latest computational advances in 3D synthetic waveform modeling, we are able to model this high frequency signal and constrain high-resolution structure on the scale of kilometers at the core-mantle boundary, for the first time. Results reveal that the lowermost part of the Hawaiian ULVZ is extremely reduced in shear wave velocity, by up to -40%. This new observation suggests a chemically distinct ULVZ with increasing iron content towards the core-mantle boundary, which has implications for Earth’s early evolutionary history and core-mantle interaction.
Delivering and implementing child and adolescent mental health training for mental health and allied professionals: A systematic review and qualitative meta-aggregation
Authors: Banwell Emily , Humphrey Neil , Qualter Pamela 
Published: January 2021

Abstract
Background:
The increasing prevalence of mental health difficulties among children and young people (CYP) suggests that early intervention is vital. A comprehensive system of care and support requires the involvement of mental health professionals, including psychologists and psychiatrists, and allied professionals, including teachers, police, and youth workers. A critical starting point is the provision of effective training, in order that these professionals can better support the mental health needs of the CYP that they encounter.
Objectives:
Given the primacy of training in the CYP mental health support system, understanding the factors that maximise potential gains and facilitate uptake is pertinent. The current review therefore located and explored qualitative research evidence, to identify the barriers and facilitators underpinning successful delivery and implementation of training focussed on the mental health of CYP, for both mental health and allied professionals.
Methods:
A systematic review and qualitative meta-aggregation were conducted, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Systematic searches were carried out using ASSIA, EMBASE, MEDLINE, NICE Evidence, PsycINFO, and Scopus databases, for papers published between 2000 and 2020. 12,448 records were identified, of which 39 were eligible for review. The records were appraised for quality using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research, and synthesised using the qualitative meta-aggregation method.
Results:
182 raw findings were extracted from the 39 papers, which were condensed into 47 sub-categories, 19 categories, and finally 5 synthesis statements. These synthesis statements reflected the barriers and facilitators influencing the training delivery process (“support”; “content, design, and planning”), and the implementation of training into the workplace (“context”; “perceived value”; “organisational factors”).
Conclusions:
The synthesis statements and underlying categories provide practical recommendations for those designing, delivering, or implementing CYP mental health training. The review provides a robust evidence-based foundation to “common-sense” principles, drawing them into a coherent and organised framework using a synthesis method grounded in pragmatism.

Stereodynamical Control of Nonadiabatic Quenching Dynamics of OH(A2S+) by H2: Full-Dimensional Quantum Dynamics
Authors: Zhao Bin , Han Shanyu , Malbon Christopher , Manthe Uwe , Yarkony David , Guo H. 
Published: January 2021

Abstract
The breakdown of the Born-Oppenheimer approximation is omnipresent in chemistry, but our detailed understanding of the nonadiabatic dynamics is still incomplete. In the present work, nonadiabatic quenching of electronically excited OH(A2S+) molecules by H2 molecules is investigated by a full-dimensional quantum dynamical method using a high quality diabatic potential energy matrix. Good agreement with experiment is found for the OH(X2P) ro-vibrational and L-doublet distributions. Furthermore, the nonadiabatic dynamics is shown to be controlled by stereodynamics, namely the orientation of the two reactants. The uncovering of a major (in)elastic channel, neglected in all previous analyses, resolves a long-standing experiment-theory disagreement concerning the branching ratio of the two electronic quenching channels.
Self-generated oxygen gradients control collective aggregation of photosynthetic microbes

Published: January 2021

Abstract
For billions of years photosynthetic microbes have evolved under the variable exposure to sunlight in diverse ecosystems and microhabitats all over our planet. Their abilities to dynamically respond to alterations of the luminous intensity, including phototaxis, surface association and diurnal cell cycles, are pivotal for survival, far more than any other environmental cues. If these strategies fail in the absence of light, the microbes can still sustain essential metabolic functionalities and motility by switching their energy production from photosynthesis to oxygen respiration. For suspensions of motile microbes above a critical density we demonstrate that this switch reversibly controls collective microbial aggregation. Aerobic respiration dominates over photosynthesis in conditions of low light, which causes the microbial motility to sensitively depend on the local availability of oxygen. For dense microbial populations in self-generated oxygen gradients, microfluidic experiments and continuum theory based on a reaction-diffusion mechanism show that oxygen-regulated motility enables the collective emergence of highly localized regions of high and low cell densities.

Abstract
The implementation of nano-engineered composite oxides opens up the way towards the development of a novel class of superior energy materials. Vertically aligned nanocomposites are characterized by a coherent, dense array of vertical interfaces, which allows for the extension of local effects to the whole volume of the material. Here, we use such a unique architecture to fabricate highly electrochemically active nanocomposites of lanthanum strontium manganite and doped ceria with unprecedented stability and straight applicability as functional layers in solid state energy devices. Direct evidence of synergistic local effects for enhancing the electrochemical performance, stemming from the highly ordered phase alternation, is given here for the first time using atom-probe tomography combined with oxygen isotopic exchange. Interface-induced cationic substitution, enabling lattice stabilization, is presented as the origin of the observed long-term stability. These findings reveal a novel route for materials nano-engineering based on the coexistence between local disorder and long-range arrangement.

Published: January 2021

Abstract
Background Growing large crop monocultures and heavily using pesticides enhances the chance of evolution of pesticide-insensitive pests and pathogens. To reduce pesticide use in crop cultivation, the application of priming-active compounds (PrimACs) is a welcome alternative. PrimACs strengthen the plant immune system and can thus help to protect plants with lower amounts of pesticides. PrimACs can be identified, for example, by their capacity to enhance the respiratory activity of parsley cells in culture as determined by the oxygen transfer rate (OTR) using the respiration activity monitoring system (RAMOS) or its miniaturized version, µRAMOS. The latter was designed for with suspensions of bacteria and yeast cells in microtiter plates (MTPs). So far, RAMOS or µRAMOS have not been applied to adult plants or seedlings which would overcome the limitation of (µ)RAMOS to plant suspension cell cultures. Results In this work, we introduce a modified µRAMOS for analysis of plant seedlings. The novel device allows illuminating the seedlings and records the respiratory activity in each well of a 48-well MTP. To validate the suitability of the setup for identifying novel PrimAC in Arabidopsis thaliana, seedlings were grown in MTP for seven days and treated with the known PrimAC salicylic acid (SA; positive control) and the PrimAC candidate methyl 1-(3,4-dihydroxyphenyl)-2-oxocyclopentane-1-carboxylate (Tyr020). Twenty-eight h after treatment, the seedlings were elicited with flg22, a 22-amino acid peptide of bacterial flagellin. Upon elicitation, the respiratory activity was monitored. The evaluation of the OTR course reveals Tyr020 as a likely PrimAC. The priming-inducing activity of Tyr020 was confirmed using molecular biological analyses in A. thaliana seedlings. Conclusion We disclose the suitability of µRAMOS for identifying PrimACs in plant seedlings. The difference in OTR during a night period between primed and unprimed plants was clearly distinguishable after elicitation with flg22. Thus, it has been shown, that the µRAMOS device can be used for a reliable screening for PrimACs in plant seedlings.

Published: January 2021

Abstract
SERS spectroscopy is successfully employed in this work to reveal different components integrating the cochineal colorant employed for dying archaeological textile samples from the Arica region in North Chile. This analysis was done by in-situ experiments that does not imply the material (colorant and biomolecules) extraction. The spectroscopic analysis of the archaeological textiles by SERS reveals the presence of bands attributed to carminic acid and nucleobases, mainly adenine and guanine. The identification of these biomolecules was also verified in raw cochineal extract and in cochineal dyed replica wool fibers fabricated by us following ancient receipts. The effect of Al on the complexation of carminic acid and other biomolecules was also tested in order to understand the changes induced by the metal interaction on the colorant structure. This study revealed that Al can also complex biomolecules existing in the cochineal extract. In particular, guanine residue seems to interact strongly with the metal, since SERS bands of this residue are enhanced. Furthermore, a theoretical analysis on the interaction of carminic acid and a silver surface was also performed in order to better understand the interaction mechanism between carminic acid and a metal surface that leads to the final SERS spectrum. The results of the present work will be very useful in the identification of different molecules and metal complexes that may be forming part of the cochineal colorant found in archaeological materials.
The Relationship Between Perceived Barriers for Physical Activity and Depression in Low Active Community-Dwelling Women

Published: January 2021

Abstract
Background: Women are less physically active, report greater perceived barriers for exercise and show higher levels of depression. This contributes to high global disability. The relationship between perceived barriers for physical activity and depressive symptoms in women remains largely unexplored. The aims of this cross-sectional analysis were to examine the association between physical activity barriers and depressive symptoms, and identify types of barriers in low active community dwelling women. Methods: 318 physically inactive women aged 25-65 years completed the Barriers to Being Active Quiz (BBAQ) developed by the Centers for Disease Control and Prevention, and the Center for Epidemiological Studies Depression Scale (CES-D) at the baseline visit of the mobile phone based physical activity education (mPED) trial. The BBAQ consists of 6 subscales (lack of time, social influence, lack of energy, lack of willpower, fear of injury, lack of skill, and lack of resources). We used multivariate regression analyses, correcting for sociodemographics. Results: Higher physical activity barriers were associated with greater depression scores (linear effect, estimate=0.75, 95% CI: 0.39 – 1.12, p<0.001). This effect appeared to taper off for the higher barrier scores (quadratic effect, estimate: -0.02, 95% CI: -0.03 – -0.01, p=0.002). Exploratory analyses indicated that score differences were most driven by the social influence (p=0.027) and lack of energy subscales (p=0.017).Conclusions: Higher depression scores were associated with higher physical activity barriers. Social influence and lack of energy were particularly important barriers. Thus, addressing these barriers may improve the efficacy of physical activity interventions in women with higher depressive symptoms. However, a randomized controlled trial is warranted.
