Published: July 2022

Abstract
Double layered hydroxide (LDH) nanomaterials were prepared by the co-precipitation method and characterized by X-ray diffraction. The XRD pattern of LDH showed a rhombohedra phase with a hexagonal lattice. After blending polyvinyl alcohol/polyethylene oxide (PVA/PEO) by casting method, the as-prepared LDH was loaded to the polymer blend in different amounts; 0, 1, 3, 5, 7, 8, and 10 wt.%. The results of the XRD revealed a significant change in the crystallinity of the polymer nanocomposite films. Energy-dispersive X-ray spectroscopy (EDX) was used to characterize the LDH nanomaterials. The ratio of Zn and Fe (4:1) in LDH nanopowder is confirmed. Field-emission scanning electron microscopy (FE-SEM) was used to test the morphology of the LDH nanopowder and polymer nanocomposites. A homogenous rough surface in the form of paper-like layers was observed in LDH nanoparticles. Fourier transform infrared (FTIR) reflectance spectra were measured at room temperature in the wavenumber range 400 – 4000 cm−1. It was noted that there are no interactions between PVA/PEO blend and LDH nanoparticles. The UV–vis spectra of the nanocomposite films were discussed to determine different optical parameters to look for the applications of the studied nanocomposite films if any.

Abstract
Aim This study aimed to explore new bone formation around implants in extraction sockets after immediate implantation in the canine posterior mandible in response to different treatments. Materials and methods The 4th premolar and the 1st molar of six Labrador dogs were extracted from the mandible, and then, 4 dental implants were implanted. The mesial and distal gaps between the implants and the sockets were treated with one of four methods and divided into the following groups: (1) the blank group (group BG), (2) the collagen membrane (CM) group (group C), (3) the deproteinized bovine bone mineral (DBBM) group (group D), and (4) the DBBM+CM group (group DC). Sequential fluorescent labeling was performed at 4, 8, and 10 weeks after the operation. After 12 weeks, the dogs were euthanized, and specimens were collected for micro-CT scanning and histological analysis. Results The survival rate was 100%. Micro-CT showed significant differences in bone mineral density (BMD) and bone volume fraction (BVF) among the four groups (P = 0.040, P = 0.009); other indicators were not significantly different among the groups. Histological analysis showed that the proportion of new bone formation and bone-to-implant contact (BIC) were not significantly different among the groups. Conclusion The current study demonstrated that although DBBM can significantly increase BMD and BVF, the use of DBBM and CM did not significantly improve bone formation in extraction sockets around the implants.Clinical relevance According to the current animal experiment, DBBM and CM may not have a significant impact on bone formation in the extraction socket of IIP in the posterior mandible, suggesting that there was no sufficient reason to recommend the application of these two kinds of materials in mesiodistal extraction sockets around IIP in mandibular molar sites.

Abstract
Background
The Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) is developed to evaluate the shoulder and elbow function in overhead athletes. To date, the score has not been adapted into Finnish language. The aim of this study was to perform a cross-cultural adaptation of the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) into Finnish language and evaluate its validity, reliability, and responsiveness in overhead athletes.
Methods
Forward-backward translation method was followed in the cross-cultural adaptation process. Subsequently, 114 overhead athletes completed the Finnish version of KJOC score, Disabilities of the Arm, Shoulder and Hand (DASH), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) and RAND-36 to assess validity of the KJOC score. To evaluate reliability and responsiveness, the participants filled in the KJOC score 16 days and 8 months after the first acquisition. Validity, reliability, and responsiveness of the Finnish KJOC score were statistically tested.
Results
Minor modifications were made during the cross-cultural translation and adaptation process, which were related to culture specific terminology in sports and agreed by an expert committee. Construct validity of the KJOC score was moderate to high, based on the correlations with DASH (r=-0.757); DASH sports module (r=-0.667); ASES (r = 0.559); and RAND-36 (r = 0.397) questionnaires. Finnish KJOC score showed excellent internal consistency (α = 0.92) and good test-retest reliability (ICC = 0.77) with acceptable measurement error level (SEM 5.5; MDC 15.1). Ceiling effect was detected for asymptomatic athletes in each item (23.2–61.1%), and for symptomatic athletes in item 5 (47.4%). Responsiveness of the Finnish KJOC score could not be confirmed due to conflicting follow-up results.
Conclusion
The Finnish KJOC score was found to be a valid and reliable questionnaire measuring the self-reported upper arm status in Finnish-speaking overhead athletes.

Abstract
Objective
To evaluate usability of and satisfaction with OrCam MyEye, a finger-size wearable assistive technology device for visually impaired during real-world tasks.
Methods
This prospective multicenter study was conducted on visually impaired people recruited from 5 vision rehabilitation centers. Patients performed real-world tasks such as near and distance reading, money handling, colour identification and faces recognition in 2 different scenarios: without using any low vision aid and with OrCam. System Usability Scale (SUS), Patient’s Global Impression of Change (PGIC), the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) and the Psychosocial Impact of Assistive Devices Scale (PIADS) were administered after the use of the OrCam device.
Results
Among the 100 participants, use of OrCam MyEye device improved many daily-living tasks (F = 1.67, P < .05), and in particular reading and face recognition. Multivariate logistic regression showed that age and visual field defect explained 89% of the variation in efficacy of the device. Nearly half (45%) of the participants indicated a positive rating with the SUS. The PGIC rates showed a minimal improvement with a mean score of 4.2 (SD:1.8). The most highlighted parameter with the QUEST 2.0 test was “ease of use” in 58% (48 subjects). The PIADS indicator showed that the device positively impacted on the daily-living tasks of users (r2 = 0.72, P < .05). Regression modelling demonstrated a good relation between the questionnaires scores and demographic, disease and visual factors (P < .05).
Conclusions
OrCam MyEye allowed visually impaired people to read, handle money and face recognition independently. This device may offer to these subjects to be independent.
Novel Estimation Technique for the Carrier-to-Noise Ratio of Wireless Medical Telemetry Using Software-Defined Radio with Machine-Learning
Authors: Ishida Kai 
Published: July 2022

Abstract
In this study, we developed a novel machine-learning model to estimate the carrier-to-noise ratio (CNR) of wireless medical telemetry (WMT) using time-domain waveform data measured by a low-cost software-defined radio. If the CNR can be estimated automatically, the management of the electromagnetic environment of WMT can be easier. Therefore, we proposed a machine-learning method for estimating CNR. According to the performance evaluation results by 5-segment cross-validation on 704 types of measured data, CNR was estimated with 99.5% R-square and 0.844 dB mean absolute error using a gradient boosting regression tree. The gradient boosting decision tree classifiers predicted whether the CNR exceeded 30 dB with 99.5% accuracy. The proposed method is effective for investigating electromagnetic environments in clinical settings.
Immortal Data: A qualitative exploration of patients’ understandings of genomic data
Authors: Lyle Kate , Weller Susie , Horton Rachel , Lucassen Anneke 
Published: July 2022

Abstract
As ambitions to ‘mainstream’ genetic and genomic medicine in the UK advance, genomic data is becoming increasingly familiar to patients. Unlike the results of many other medical investigations which are linked to the time of sample collection, genomic testing provides immortal data that do not change across time, and may have relevance for relatives and generations far beyond the patient’s own lifespan. This immortality raises new ethical challenges for healthcare professionals, patients and families alike, such as ensuring consent for possible future interpretations; determining when data should be reinterpreted; balancing the confidentiality of patients and duties of care towards others. Given the range of ethical challenges it raises, it is essential that the immortality of genomic data is brought to the fore. This paper reports on a qualitative study exploring the perspectives of patients and relatives participating in genomic testing, and suggests that their engagements with this immortality are shaped by: the simplicity of sample provision; understandings of heritability; and notions of genomic data as a collective resource. We discuss the implications this holds for practice and argue that the immortality of genomic data must take a more prominent position in patient and health care professional interactions.

Abstract
Background: The increased risk of myocardial infarction has been well established following and infection, however, few articles explore the complications and mortality rates associated with simultaneous infections and myocardial infarctions. Our article explores this scope with the hope of better understanding how the management of infections in patients with MI will lead to better outcomes in terms of morbidity and mortality. Methods: 1,197 patients diagnosed with myocardial infarction were included in this study. A comparison between infected and non-infected patients was made in terms of mortality and complication rate. Pearson's chi squared test was used to compare categorical variables. Means were compared through ANOVA test after checking the data for normality and homoscedasticity. Taking dichotomous outcomes as dependent variables, and sociodemographic and biological characteristics as independent variables, a likelihood ratio backward stepwise method was used to conduct dichotomous logistic regressions.Results: Wound, sputum, blood, and urine infections were associated with increased same admission mortality and complications. Length of stay was significantly elevated in patients with concomitant infection and even more elevated when bacteria was cultured from other sites.Conclusion: Patients with myocardial infarction and concomitant infections had a significantly increased risk of same admission complications, mortality, and length of stay.
Gravity-Assist as a Possible Solution to Save Earth from Global Warming
Authors: Rahvar Sohrab 
Published: July 2022

Abstract
Global warming is one of the problems of human civilization and decarbonization policy is the main solution to this problem. In this work, we propose an alternative method of using the gravity-assist by the asteroids to increase the orbital distance of the Earth from the Sun. While this proposal is far from the present day technical potential however, we show that in principle this is a doable project.Let us assume manipulating the orbit of asteroids in the asteroid belt by solar sailing and propulsion engines to guide them towards the Mars orbit. A gravitational scattering from Mars can put asteroids in a favorable direction to provide an energy loss scattering from the Earth. The result would be increasing the orbital distance of the earth and consequently cooling down the Earth's temperature. We calculate the increase in the orbital distance of the earth for each scattering.

Abstract
Kidney fibrosis is a common pathway that leads to chronic kidney disease. Angiotensin II type-1 receptor (AT1R)-associated protein (ATRAP) was originally identified as an AT1R-binding protein. Previously, we reported that systemic knockout of ATRAP exacerbates kidney fibrosis in aged mice. Although these effects of ATRAP appeared to be AT1R-independent actions, the molecular mechanism remains poorly understood. To elucidate the molecular mechanism of ATRAP independent of AT1R, we explored novel ATRAP-interacting proteins. Mass spectrometric analysis of the immunoprecipitants of a Flag-tagged ATRAP complex revealed 376 candidate proteins that potentially interact with ATRAP. Gene ontology analysis revealed that proteins related to vesicle trafficking, membrane transport, and many membrane proteins, including transferrin receptor 1 (TfR1), were enriched. Because TfR1 promotes cellular iron uptake and iron is a key factor involved in kidney fibrosis, we focused on TfR1 and confirmed that it interacts with ATRAP. In addition, our findings revealed that enhanced ATRAP expression decreased cell-surface TfR1 expression without altering the overall cellular TfR1 expression levels. Furthermore, enhanced ATRAP expression attenuated cellular iron levels. Together, our results highlight the role of ATRAP as a suppressor of TfR1 that functions by facilitating TfR1 internalization, which affects iron metabolism.
Research on suppression effect of different types of inert dust on coking coal dust explosion pressure in a confined space
Authors: Liu Tianqi 
Published: July 2022

Abstract
To study the suppression effect of inert dust on coking coal dust explosion pressure, NaCl, KCl and NH4H2PO4 are selected for explosion suppression. It is found that as dust cloud mass concentration increases in the range of 300~500 g/m3, both Pmax and (dP/dt)max increase first and then decrease. The coal dust explosion pressure decreases continuously as the mass percentages of inert dust mixed into coal dust increase from 0% to 70%. The explosion no longer occurs when the mass percentage of NH4H2PO4 mixed into coal dust is 70%, indicating that NH4H2PO4 is more effective than that of NaCl and KCl. The smaller the particle size of inert dust NH4H2PO4, the more obvious the suppression effect on dust explosion. The coal dust no longer explodes when the mass percentage of NH4H2PO4 mixed into coal dust is 60% and the particle size of NH4H2PO4 is 25~38 μm, which proves that decreasing the particle size of NH4H2PO4 is important for suppressing explosion.

Published: July 2022

Abstract
Purpose
The objective of this study is to determine if there is a significant correlation between race/ethnicity and total thyroid volume among patients with benign thyroid disease. Our hypothesis is that patients of racial and ethnic minorities may present with enlarged, non-cancerous thyroids more frequently than white patients.
Methods
This is a retrospective cohort study of 457 patients (N = 457) diagnosed with benign thyroid disease between 2008 and 2020 at Montefiore Medical Center. Data were taken from an existing database and the electronic health record. The primary outcome was total thyroid volume (cm3/mL) calculated from ultrasound measurements. The secondary outcome was the maximum dimension (cm) of the largest thyroid nodule.
Results
Black patients had a mean thyroid volume (± SD) of 142.7 (± 131.1) and a mean maximum nodule dimension of 4.3 (± 1.9). White patients had a mean thyroid volume of 74.7 (± 128.0) and a mean maximum nodule size of 3.0 (± 1.5). Race was significantly correlated with total thyroid volume (p = .0007). Black race specifically was significantly correlated with total thyroid volume (p = .0008, 95% CI [.209, .794]) and maximum nodule dimension (p = .05, 95% CI [.006, 1.278]).
Conclusion
Black patients had significantly larger total thyroid volumes and nodules compared to white patients. Thyroid volume was not associated with measures of socioeconomic status such as insurance type or estimated income. Although these findings illustrate an important relationship between race and thyroid volume, further research is required to determine the etiology of this discrepancy.
Impact of COVID-19 on hospital visits for non-traumatic dental conditions in Ontario, Canada
Authors: Singhal Sonica , Dhar Badal , Ayoub Nardin , Quiñonez Carlos 
Published: July 2022

Abstract
Background and Rationale: As general health care is publicly funded in Canada and oral health care is not, many people seek care from hospitals for their dental problems. This study assessed if the unprecedented times of COVID-19 affected the hospital visits for dental emergencies, making disadvantaged populations further vulnerable for attendance of their dental problems. Methods: Data from IntelliHealth Ontario for emergency department (ED) visits, day surgery visits, and hospitalizations associated with non-traumatic dental conditions (NTDCs) were retrieved for years 2016 to 2020 to assess trends before COVID-19 and changes, if any, for the year 2020. Trends by month, for the years 2019 and 2020, to make straight comparisons and understand the effects of lockdown in Ontario, was also analyzed. Results: In the year 2020, there was a reduction of 40% in day surgeries, 21% in ED visits and 8% in hospitalizations compared to 2019. Stratified by month, largest reductions were observed in April 2020: 96% in day surgeries; 50% in ED visits; and 38% reductions in hospitalizations when compared to the same month of 2019. In May 2020, day surgeries and ED visits though remained reduced, hospitalization rates increased by 31%. Conclusion: Hospital EDs are inefficient avenues for handling dental emergencies. Nevertheless, they do remain a care setting that is sought by many for dental problems, and if the need for hospitalization and day surgery is there, this care setting is an important avenue for dentally related medical care. Perhaps unsurprisingly, COVID-19 has lessened the opportunity and capacity for such care.Practical implications: Administrators and policy makers can utilize this information to strategize on augmenting community infrastructure for building more effective, and cost-efficient avenues of care for timely management of dental problems.

Published: July 2022

Abstract
Purpose Conducting research about the metal accumulation process of wetland plants and relevant rhizosphere mechanism can better understand the biogeochemical behavior of metals in riparian wetland. However, little relative information is available for riparian wetland. Methods In this study, we explored the copper accumulation process of dominant plant of Artemisia and rhizosphere mechanism under different water regime (flooding condition [FC], dry condition [DC] and alternate dry and flooding condition [DFC]) in riparian wetland of Poyang Lake.Results The result indicated that continuous or intermittent flooding may impede the accumulation and transformation of Cu by Artemisia. The correlation and multivariate analysis indicated that rhizosphere pH, Cu fraction and iron plaque on root surface can significantly influence Cu accumulation process. The transformation of exchangeable fraction to carbonate bound fraction and organic fraction under DFC and FC treatments may impede the accumulation of Cu in Artemisia. Formation of iron plaque under DFC and DC treatments can enhance the Cu accumulation in roots, but impede the translocation of Cu to aboveground tissues. Higher rhizosphere pH under DFC and FC treatments may impede the translocation of Cu by enhancing formation of iron plaque. Additionally, the growth status, bioaccumulation factor, translocation factor and root/aerial Cu content indicated that Artemisia can accumulate quantitative Cu in roots, but not suitable for phytoextracting Cu contaminated soil because of significant decrease of biomass with Cu addition, especially under DFC and FC treatments. Conclusion Altogether, our results indicate that Cu accumulation processes and ability is impeded by DFC and FC treatments.
