Published: September 2020

AbstractA series of La1-xCexCoO3 perovskite nanoparticles with rhombohedral phases was synthesized via sol–gel chemical process. X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), Electron Diffraction Spectroscopy (EDS), Thermogravimetric Analysis (TGA), UV–Vis spectroscopy, Fourier Transform Infrared spectra (FTIR), Nitrogen Adsorption/desorption Isotherm, Temperature Program Reduction/Oxidation (TPR/TPO), X-ray Photoelectron Spectroscopy (XPS) techniques were utilized to examine the phase purity and chemical composition of the materials. An appropriate doping quantity of Ce ion in the LaCoO3 matrix have reduced the bond angle, thus distorting the geometrical structure and creating oxygen vacancies, which thus provides fast electron transportation. The reducibility character and surface adsorbed oxygen vacancies of the perovskites were further improved, as revealed by H2-TPR, O2-TPD and XPS studies. Furthermore, the oxidation of benzyl alcohol was investigated using the prepared perovskites to examine the effect of ceria doping on the catalytic performance of the material. The reaction was carried out with ultra-pure molecular oxygen as oxidant at atmospheric pressure in liquid medium and the kinetics of the reaction was investigated, with a focus on the conversion and selectivity towards benzaldehyde. Under optimum reaction conditions, the 5% Ce doped LaCoO3 catalyst exhibited enhanced catalytic activity (i.e., > 35%) and selectivity of > 99%, as compared to the other prepared catalysts. Remarkably, the activity of catalyst has been found to be stable after four recycles.
Koala immunogenetics and chlamydial strain type are more directly involved in chlamydial disease progression in koalas from two south east Queensland koala populations than koala retrovirus subtypes

Published: September 2020

AbstractChlamydial disease control is increasingly utilised as a management tool to stabilise declining koala populations, and yet we have a limited understanding of the factors that contribute to disease progression. To examine the impact of host and pathogen genetics, we selected two geographically separated south east Queensland koala populations, differentially affected by chlamydial disease, and analysed koala major histocompatibility complex (MHC) genes, circulating strains of Chlamydia pecorum and koala retrovirus (KoRV) subtypes in longitudinally sampled, well-defined clinical groups. We found that koala immunogenetics and chlamydial genotypes differed between the populations. Disease progression was associated with specific MHC alleles, and we identified two putative susceptibility (DCb 03, DBb 04) and protective (DAb 10, UC 01:01) variants. Chlamydial genotypes belonging to both Multi-Locus Sequence Typing sequence type (ST) 69 and ompA genotype F were associated with disease progression, whereas ST 281 was associated with the absence of disease. We also detected different ompA genotypes, but not different STs, when long-term infections were monitored over time. By comparison, KoRV profiles were not significantly associated with disease progression. These findings suggest that chlamydial genotypes vary in pathogenicity and that koala immunogenetics and chlamydial strains are more directly involved in disease progression than KoRV subtypes.

AbstractLiposomal amphotericin B (L-AMB) is a broad-spectrum antifungal drug that is used to treat fungal infections. However, clinical evidence of its use in patients with renal failure is limited. Here, we aimed to identify factors associated with acute kidney injury (AKI) in patients administered L-AMB. We retrospectively utilized a combination of Diagnosis Procedure Combination data and laboratory data obtained from hospitals throughout Japan between April 2008 and January 2018. In total, 507 patients administered L-AMB were identified. After L-AMB treatment initiation, AKI, which was defined as a ≥ 1.5-fold increase within 7 days or ≥ 0.3 mg/dL increase within 2 days in serum creatinine according to the KDIGO criteria, was recognized in 37% of the total patients (189/507). The stages of AKI were stage 1 in 20%, stage 2 in 11%, and stage 3 in 7%. Five factors were associated with AKI of all stages: prior treatment with angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers or carbapenem; concomitant administration of catecholamines or immunosuppressants; and ≥ 3.52 mg/kg/day of L-AMB dosing. Serum potassium < 3.5 mEq/L before L-AMB therapy was associated with severe AKI of stage 2 and 3. Altogether, these factors should be carefully considered to reduce the occurrence of AKI in patients administered L-AMB.

AbstractCardiac and aortic characteristics are crucial for cardiovascular disease detection. However, noninvasive estimation of aortic hemodynamics and cardiac contractility is still challenging. This paper investigated the potential of estimating aortic systolic pressure (aSBP), cardiac output (CO), and end-systolic elastance (Ees) from cuff-pressure and pulse wave velocity (PWV) using regression analysis. The importance of incorporating ejection fraction (EF) as additional input for estimating Eeswas also assessed. The models, including Random Forest, Support Vector Regressor, Ridge, Gradient Boosting, were trained/validated using synthetic data (n = 4,018) from an in-silico model. When cuff-pressure and PWV were used as inputs, the normalized-RMSEs/correlations for aSBP, CO, and Ees(best-performing models) were 3.36 ± 0.74%/0.99, 7.60 ± 0.68%/0.96, and 16.96 ± 0.64%/0.37, respectively. Using EF as additional input for estimating Eessignificantly improved the predictions (7.00 ± 0.78%/0.92). Results showed that the use of noninvasive pressure measurements allows estimating aSBP and CO with acceptable accuracy. In contrast, Eescannot be predicted from pressure signals alone. Addition of the EF information greatly improves the estimated Ees. Accuracy of the model-derived aSBP compared to in-vivo aSBP (n = 783) was very satisfactory (5.26 ± 2.30%/0.97). Future in-vivo evaluation of CO and Eesestimations remains to be conducted. This novel methodology has potential to improve the noninvasive monitoring of aortic hemodynamics and cardiac contractility.

Authors: DeJarnette Katherine M. , Wegner Jane R. 
Published: September 2020

Purpose
This survey sought to gather information from graduate programs in speech-language pathology concerning their preservice education in augmentative and alternative communication (AAC). The results were compared to similar previous surveys to identify improvements, continued challenges, and common barriers in providing preservice education in AAC.

Method
Two hundred fifty-one program directors, department chairs, clinical directors, and faculty members of Council on Academic Accreditation graduate programs in speech-language pathology were surveyed to explore the characteristics of preservice education in AAC.

Results
A total of 85 survey responses were received for a 33.8% return rate. Data revealed that there has been a general trend toward an increase in the number of graduate programs that offer coursework in AAC, the number of graduate students who are receiving knowledge and skills in AAC, and the number of students who obtain clinical experiences in AAC. However, results indicate that graduate programs in speech-language pathology continue to face barriers in providing comprehensive preservice education in AAC. Specifically, these barriers included limited funding, lack of faculty members with expertise in AAC, access to AAC systems and technologies, and time constraints. Results from this study may be helpful in addressing said barriers in future practice.

Conclusions
Graduate programs in speech-language pathology have improved their preservice education in AAC over the past 10 years. Survey responses indicate a continued need for improvement in clinical experiences, funding, and an increase in the number of faculty members with expertise in AAC.

Published: September 2020

PurposeMore than 460 million people are impacted by disabling hearing loss worldwide. Hearing loss has negative impacts across the life span and varies by individual. Specifically, in children, hearing loss has been shown to affect learning outcomes, behavioral and cognitive growth, and psychosocial development. In adults, hearing loss has been shown to affect quality of life, social isolation, depression, and anxiety. The purpose of this review is to advance the understanding of the latest research in the development of new treatments of hearing loss, including gene therapy, stem cell therapy, and pharmacotherapies. We address the use of animals to model human hearing loss and the importance of animals in previous discoveries and developing new therapies. We highlight the importance of early identification for better speech and developmental outcomes specifically in pediatric individuals. Lastly, we review new possibilities in the prevention of hearing loss and the path to translation into practice.ConclusionsResearch and development of new therapies to treat hearing loss is an ever growing field with many notable successes. However, clinical translation still poses many challenges. Many discoveries related to gene therapy, stem cell therapy, and pharmacotherapy are in the early phases of clinical trials and hold promise. This review empowers audiologists to be aware of these most recent developments and be conscious of the evolving future landscape of treatment and management of hearing loss.

Abstract
Introduction Recent studies have addressed the role of micronutrients in
fertilization, such as vitamin D. The present study aims to explore the effects
of using calcitriol, an active form of vitamin D, on IVF results in women with
vitamin D deficiency.
Method This double-blinded randomized clinical trial was done on 180
infertile women, undergone IVF treatment. Out of them, 95 were found to have
vitamin D deficiency (blood serum 25-dihydroxy vitamin D <30
ng/ml). Fifty one women in experimental group were treated with two 0.25
µg calcitriol pills daily during 4 weeks (discontinued 8 hours prior to
the embryo transfer) and 44 subjects to the placebo group (mean vitamin D
deficiency 27.5 ±1.8 in case group vs. 27.6±1.8 in control
group, P>0.05). Final analysis includes outcomes of chemical and
clinical pregnancy was done on 74 women (including 36 in case and 38 in control
group).
Results Our study showed that in the experimental group, chemical
pregnancy success was significantly higher than that in the control group, 31.4
vs. 18.2% (P<0.05). However, there were no significant
differences between the 2 groups in reaching the clinical pregnancy stage
(25.5% in case group vs. 13.6% in control group) and
continuation of pregnancy into week 20 (9.8% in case group vs.
11.6% in control group) (P>0.05).
Conclusion Calcitriol administration by improving the implantation
process can significantly increase the chances of successful IVF cycle results
in infertile women with vitamin D deficiency.

Published: September 2020

AbstractMultiple intraoperative strategies are described to achieve full extension in total knee arthroplasty, but only a few studies have assessed the effect of the flexion gap on intraoperative improvement in flexion contracture. The aim of this study was to determine whether posterior condylar offset, in isolation, independently affects extension at the time of total knee arthroplasty.Two hundred and seventy-eight patients who underwent total knee arthroplasty for knee osteoarthritis and flexion contracture ≥ 5 degrees between January 2008 and July 2018 were included in this study. Patients with other factors that could affect knee extension at the time of surgery were excluded. We recorded the thickness of posterior femoral condyle bone resected as well as the thickness of the posterior femoral component chosen for each patient. Patients' knee extension was recorded under anesthetic, prior to resection and intraoperatively after total knee replacement.Average thickness of bone resection for the posteromedial femur was 12.64  ± 1.65 mm and for the posterolateral femur was 10.38  ± 1.52 mm. Using a linear regression model, we found that changes in posterior offset and implant downsizing influenced correction of fixed flexion deformity at the time of surgery. When patients had a combined posteromedial and posterolateral offset 2 mm thinner than the thickness of bone resected, there was an average correction of 3.5 degrees of flexion contracture.Our study demonstrated that posterior femoral condyle offset is an independent variable affecting correction of flexion contracture at the time of surgery in a gap balanced cruciate-retaining total knee arthroplasty. This is a level IV evidence study.

Published: September 2020

AbstractNovel coronavirus disease 2019 is a dreaded pandemic that is going to persist, and diabetic people with poor glycemic control are at high risk of complications and death from it. Social distancing being the only way to prevent infection spread, it is very difficult to continue usual clinic-based diabetes care. So, in this review, we focus to discuss safe clinic practice recommendations, scope of telemedicine in care of follow-up patients, and diabetes self-management that every individual with diabetes needs to follow. These issues will be of utmost important as we need to understand and implement personal and social hygiene in a better way even in post lockdown period.
Kinematically Aligned Total Knee Arthroplasty Did Not Show Superior Patient-Reported Outcome Measures: An Updated Meta-analysis of Randomized Controlled Trials with at Least 2-Year Follow-up
Authors: Hiyama Shuhei , Takahashi Tsuneari , Takeshita Katsushi 
Published: September 2020

AbstractKinematically aligned total knee arthroplasty (KATKA) was developed to improve the anatomical alignment of knee prostheses, assisting in restoring the native alignment of the knee and promoting physiological kinematics. Early clinical results were encouraging, showing better functional outcomes than with mechanically aligned total knee arthroplasty (MATKA). However, there have been concerns about implant survival, and follow-up at 10 years or more has not been reported. In addition, randomized controlled trials (RCTs) comparing KATKA with MATKA have reported inconsistent results. The current meta-analysis of RCTs with a minimum of 2 years of follow-up investigated the clinical and radiological differences between KATKA and MATKA. A systematic review of the English language literature resulted in the inclusion of four RCTs. The meta-analysis found no significant difference in any of the following parameters: postoperative range of motion for flexion (mean difference for KATKA − MATKA [MD], 1.7 degrees; 95% confidence interval [CI], −1.4 to 4.8 degrees; p = 0.29) and extension (MD, 0.10 degrees; 95% CI, −0.99 to 1.2 degrees; p = 0.86); Oxford Knee Score (MD, 0.10 points; 95% CI, −1.5 to 1.7 points; p = 0.90); Knee Society Score (MD, 1.6 points; 95% CI, −2.8 to 6.0 points; p = 0.49); and Knee Function Score (MD, 1.4 points; 95% CI, −4.9 to 7.8 points; p = 0.66). In addition, there was no significant difference between KATKA and MATKA in the rate of complications requiring reoperation or revision surgery (odds ratio, 1.01; 95% CI, 0.25–4.09; p = 0.99) or in the length of hospital stay (MD, 1.0 days; 95% CI, −0.2 to 2.2 days; p = 0.092). KATKA did not increase the number of patients with poor clinical results due to implant position, particularly for varus placement of the tibial component. In this meta-analysis based on four RCTs with a minimum of 2 years of follow-up, KATKA were only relevant to cruciate retaining TKA and could not be extrapolated to posterior stabilized TKA. Patient-reported outcome measures with KATKA were not superior to those with MATKA.
The segmental phonetics and phonology of Hyow, A Tibeto-Burman language of Bangladesh
Authors: Zakaria Muhammad 
Published: September 2020

AbstractThis paper presents a description and analysis of segmental phonetics and phonology of Hyow, a Tibeto-Burman language spoken by almost 4,000 people in the southeast of Bangladesh. Hyow demonstrates phonological features which are absent in other Chin languages of the Tibeto-Burman branch. Proto Kuki-Chin initial voiceless nasals are not only preserved in Mara and Central Chin languages (Van Bik 2009: 220), but also in Hyow. Unlike other Southern Chin languages, Hyow final liquids are sometimes preserved or developed into central approximants. In fact, final liquids are preserved in Bangladesh Hyow, and in two varieties of Laitu – Keyni and Myebon – and Laisaw in the Rakhine State of Myanmar. The salient and prevalent phonological process of re-syllabification in Hyow demonstrates that the glottal stop cannot be treated as a phonetic property of the coda-cluster sonorants, which is otherwise treated as glottalized in some Chin languages by scholars, e.g. Hakha Lai (Hyman & Van Bik 2002: 114). Hyow does not show a phonemic contrast between long and short vowels which is very often found in Chin languages. Though Mainland Southeast Asian Languages are profoundly known for having sesquisyllables or reduced syllables, in Hyow, vowels of initial syllables of disyllabic words carrying grammatical morphemes are harmonized with vowels of root-initial syllables, which confirms the absence of such type of reduced syllables in Hyow. The phonological description and analysis in this paper are furthermore supported by phonetic data and illustrations. Discussions of variant phonetic realizations of certain segments have also been included.
Information structure and intonational accent in Burmese
Authors: Ozerov Pavel 
Published: September 2020

AbstractIt tends to be assumed that tonal languages do not make use of intonational tones and accent location for the purpose of conveying information structural aspects of the utterance. This study of read-aloud stories in colloquial Burmese shows that this tonal language does resort to this sort of intonational means for information-structuring reasons. The prosody of Burmese exhibits identifiable intonational patterns, which function on the level of accentual phrases. An accentual phrase constitutes the basic prosodic unit, and it is there that we find the real interaction of information structure, intonation and tone. Accentual phrases are organised around a single accent, the location of which depends on information structural factors. Sentences can consist of a single accentual phrase or a few phrases, while the exact partition into such phrases is also motivated by information- and discourse-structuring considerations.
Accuracy in atomic and molecular data
Authors: Drake G W F 
Published: September 2020

Abstract
Uncertainty estimates have long been a standard part of experimental physics, but the same has not been true on the theoretical side. However, the culture is now changing, and it is becoming more common to include uncertainty estimates in theoretical calculations of atomic and molecular properties. This tutorial paper discusses the progress that has been made in assessing the accuracy of both theory and experiment in a wide variety of circumstances, ranging from the most fundamental measurements of atomic properties such as the electron anomalous magnetic moment and the proton size puzzle in the hydrogen atom to uncertainty estimates for two- and three-electron atoms (helium and lithium), for many-electron atoms and for electron–atom scattering processes. This is followed by a discussion of uncertainties for molecules, and especially the recent remarkable progress for

and H2 treated as full three- and four-body problems without the use of the Born–Oppenheimer approximation. The paper includes a discussion of variational methods and the Hylleraas–Undheim–MacDonald theorem, which guarantees variational bounds for excited states as well as for the ground state. This leads naturally to a discussion of the use of pseudostates to perform perturbation sums over intermediate states, and a demonstration calculation for the polarizability of hydrogen. The results of well-defined uncertainty estimates have important implications for both the search for new physics beyond the standard model from high-precision measurements, and for the application of theoretical atomic and molecular data to plasma physics and to astrophysics.
The oldest extant tropical peatland in the world: a major carbon reservoir for at least 47 000 years

Published: September 2020

Abstract
Tropical peatlands in Southeast Asia cover ∼25 million hectares and exert a strong influence on the global carbon cycle. Recent widespread peatland subsidence and carbon dioxide emissions in response to human activity and climate change have been well documented, but peatland genesis remains poorly understood. Unlike coastal peatlands that established following sea-level stabilization during the mid-Holocene, inland peatlands of Borneo are little studied and have no apparent environmental constraint on their formation. Here, we report radiocarbon dates from the Upper Kapuas Basin which show inland peat formation since at least 47.8 thousand calibrated radiocarbon years before present, ka. We provide a synthesis of new and existing peat basal dates across Borneo, which shows a hiatus in peat genesis during a cool and dry period from 30 to 20 ka. Despite likely peat degradation during that period, the Upper Kapuas is still exceptionally deep, reaching a maximum depth (determined from coring) of 18 m. Our best estimate of mean peat depth over 3833 km2 of the Upper Kapuas is 5.16 ± 2.66 m, corresponding to a carbon density of 2790 ± 1440 Mg C ha−1. This is one of the most carbon-dense ecosystems in the world. It withstood the glacial-interglacial climate transition and remains mostly intact, but is increasingly threatened by land-use change.
