What Did the Psalmist Say about His Hands and Feet in Psalm 22:17?
Authors: Flowers Michael V.
Published: August 2020

Ps 22:17 is among the most controverted verses in the Hebrew Bible, both with respect to its original text and original meaning. The biggest question that text critics and interpreters struggle to answer is what the psalmist said concerning his hands and feet. With so many proposals now on the table and with debates on this text having reached an impasse, it seemed like it would be helpful to present the status quaestionis with regard to this text. Thirteen different proposals are therefore analyzed with a view to their respective merits and demerits. The goal here is to eliminate the proposals that seem least viable and to become more self-conscious about how we judge between the others.
For the People, By the Viewpoints? Realism and Idealism in Public Reason
Authors: Jayaram Athmeya
Published: August 2020

Since John Rawls, public reason theorists have attempted to show how liberal political norms could be acceptable to people with diverse religious and ethical viewpoints. However, these theories overlook the importance of the distinction between acceptability to realistic people and acceptability to viewpoints, which matters because public reason theories are committed to the former, but only deliver the latter, thereby failing to justify liberal norms. Public reason theories therefore face a dilemma: abandon realistic people and lose normative appeal, or retain realism and find a new way to justify liberalism.
Synopsis of the Asian species in the genus Zarcosia Collado & Alonso-Zarazaga, 1996 with new combinations and descriptions of fourteen new species
Authors: GOMPEL NICOLAS
Published: August 2020

This work represents a provisional inventory of Asian species placed in the genus Zarcosia Collado & Alonso-Zarazaga, 1996. Most of these species had not been reassigned since their original description under now obsolete genera, in spite of the morphological homogeneity of the genus Zarcosia Collado & Alonso-Zarazaga, 1996. The present work includes the following transfers resulting in 34 new combinations: Z. armipes (Fairmaire, 1896), comb. nov.; Z. batuensis (Werner, 1962), comb. nov.; Z. bipartita (Pic, 1901), comb. nov.; Z. capitalis (Pic, 1901), comb. nov.; Z. cephalica (Werner, 1962), comb. nov.; Z. dentatifemur (Pic, 1912), comb. nov.; Z. discoidalis (Pic, 1902), comb. nov.; Z. genjiensis (Pic, 1917), comb. nov.; Z. glaucescens (Champion, 1920), comb. nov.; Z. grandiceps (Pic, 1899), comb. nov.; Z. holosericea (Champion, 1916), comb. nov.; Z. javana (Pic, 1894), comb. nov.; Z. kempi (Blair, 1924), comb. nov.; Z. longithorax (Pic, 1899), comb. nov.; Z. lucifuga (Heberdey, 1931), comb. nov.; Z. luteitarsis (Champion, 1924), comb. nov.; Z. malayana (Werner, 1962), comb. nov.; Zarcosia nathani (Pic, 1943), comb. nov.; Z. nigrofasciata (Pic, 1899), comb. nov.; Z. obscuricornis (Pic, 1927), comb. nov.; Z. palliditarsis (Pic, 1912), comb. nov.; Z. patucki (Champion, 1924), comb. nov.; Z. picina (Fairmaire, 1893), comb. nov.; Z. plumbea (Champion, 1916), comb. nov.; Z. proprior (Pic, 1920), comb. nov.; Z. rubrobasalis (Pic, 1921), comb. nov.; Z. rufotestacea (Pic, 1901), comb. nov.; Z. sellata (Champion, 1916), comb. nov.; Z. sexdentata (Champion, 1924), comb. nov.; Z. subrobusta (Pic, 1943), comb. nov.; Z. subrufa (Champion, 1924), comb. nov.; Z. testaceitarsis (Pic, 1926), comb. nov.; Z. troglodytes (Champion, 1916), comb. nov.; Z. uncifer (Champion, 1916), comb. nov. In addition, based on the study of over 200 Asian specimens, the geographical distribution of each species is outlined. The study of numerous collections lead me to recognize 14 new species, distinguishable, at least by male genitalia, that I describe here: Zarcosia barlayi n. sp., Zarcosia bedosae n. sp., Zarcosia brunnea n. sp., Zarcosia deharvengi n. sp., Zarcosia gerstmeieri n. sp., Zarcosia ilonae n. sp., Zarcosia intermedia n. sp., Zarcosia lemairei n. sp., Zarcosia schawalleri n. sp., Zarcosia sinuata n. sp., Zarcosia spinifemur n. sp. Zarcosia srilankaensis n. sp., Zarcosia sumatrensis n. sp. and Zarcosia weigeli n. sp. Finally, I propose a new synonymy for Hylophilus picinus var. rufescens Pic, 1905 = Zarcosia picina (Fairmaire, 1893), syn. nov. and design two lectotypes, for Xylophilus picinus, Fairmaire, 1893, pres. design. and for Zarcosia subglaber Pic, 1952 pres. design.
Effect of Swell on Wind Stress for Light to Moderate Winds
Authors: Vincent Charles L. , Graber Hans C. , Collins Clarence O.
Published: August 2020

Buoy observations from a 1999 Gulf of Mexico field program (GOM99) are used to investigate the relationships among friction velocity u*, wind speed U, and amount of swell present. A U–u*sea parameterization is developed for the case of pure wind sea (denoted by u*sea), which is linear in U over the range of available winds (2–16 m s−1). The curve shows no sign of an inflection point near 7–8 m s−1 as suggested in a 2012 paper by Andreas et al. on the basis of a transition from smooth to rough flow. When observations containing more than minimal swell energy are included, a different U–u* equation for U < 8 m s−1 is found, which would intersect the pure wind-sea curve about 7–8 m s−1. These two relationships yield a bilinear curve similar to Andreas et al. with an apparent inflection near 7–8 m s−1. The absence of the inflection in the GOM99 experiment pure wind-sea curve and the similarity of the GOM99 swell-dominated low wind speed to Andreas et al.’s low wind speed relationship suggest that the inflection may be due to the effect of swell and not a flow transition. Swell heights in the range of only 25–50 cm may be sufficient to impact stress at low wind speeds.
Implementing a Parallel Version of a Variational Scheme in a Global Assimilation System at Eddy-Resolving Resolution
Authors: Cipollone Andrea , Storto Andrea , Masina Simona
Published: August 2020

Recent advances in global ocean prediction systems are fostered by the needs of accurate representation of mesoscale processes. The day-by-day realistic representation of its variability is hampered by the scarcity of observations as well as the capability of assimilation systems to correct the ocean states at the same scale. This work extends a 3DVAR system designed for oceanic applications to cope with global eddy-resolving grid and dense observational datasets in a hybridly parallelized environment. The efficiency of the parallelization is assessed in terms of both scalability and accuracy. The scalability is favored by a weak-constrained formulation of the continuity requirement among the artificial boundaries implied by the domain decomposition. The formulation forces possible boundary discontinuities to be less than a prescribed error and minimizes the parallel communication relative to standard methods. In theory, the exact solution is recovered by decreasing the boundary error toward zero. In practice, it is shown that the accuracy increases until a lower bound arises, because of the presence of the mesh and the finite accuracy of the minimizer. A twin experiment has been set up to estimate the benefit of employing an eddy-resolving grid within the assimilation step, as compared with an eddy-permitting one, while keeping the eddy-resolving grid within the forecast step. It is shown that the use of a coarser grid for data assimilation does not allow an optimal exploitation of the present remote sensing observation network. A global decrease of about 15% in the error statistics is found when assimilating dense surface observations, and no significant improvement is seen for sparser observations (in situ profilers).

Authors: Hung Wei-Chen , Lo Wu-Chia , Fang Kai-Min , Cheng Po-Wen , Wang Chi-Te
Published: August 2020

Objective:

Repeated surgical interventions are usually required to control recurrent respiratory papillomatosis (RRP), but at considerable risk of worsened postoperative voice quality. Potassium titanyl phosphate (KTP) laser has been reported to effectively manage RRP; however, voice quality after repeated procedures has not been investigated.

Methods:

This study recruited 16 patients with RRP treated using KTP laser between 2013 and 2019. KTP laser procedures were performed under general anesthesia via direct suspension laryngoscope or under local anesthesia via flexible endoscope, depending on the need for pathological proof, patient tolerance, and lesion size and location. Disease control was investigated by videolaryngostroboscopy. Voice outcome was evaluated using a 10-item voice handicap index (VHI-10), acoustic and perceptual analyzes.

Results:

We reviewed the medical records of 11 male and 5 female patients with RRP (age range: 23-73 years). Five patients received KTP laser once, six patients received it 2 to 5 times, and five patients received 6 to 15 procedures. Median VHI-10 decreased from 28.3 to 12.0 points after the initial procedure and were maintained at 10.1 to 11.0 points following subsequent procedures ( P < .01, generalized estimating equation). Acoustic and perceptual analysis of voice quality also revealed significant improvements ( P < .01), which remained stable even after 6 to 10 KTP laser procedures. Minor adverse events included slight fibrotic change of vocal folds and glottic web, but these did not significantly alter postoperative voice quality.

Conclusion:

This longitudinal follow-up study revealed that serial KTP laser procedures can effectively control RRP while preserving phonatory function and maintaining adequate voice quality.

Nature Enhanced Meditation: Effects on Mindfulness, Connectedness to Nature, and Pro-Environmental Behavior
Authors: Ray Travis N. , Franz Scott A. , Jarrett Nicole L. , Pickett Scott M.
Published: August 2020

Previous research suggests that meditation, a mindfulness exercise, could result in increased connectedness to nature and pro-environmental behavior. Exposure to nature also is associated with these outcomes. It was hypothesized that meditation alongside stimuli reminiscent of the natural environment would produce enhanced effects. Participants ( N = 97) were randomly assigned to complete a 4-week online meditation program consisting of a guided meditation paired with either nature sounds (“nature group”) or spa-like sounds (“control group”). Mindfulness, connectedness to nature, and pro-environmental behavior were assessed before and after the program. Meditation, in general, produced increases in mindfulness, connectedness to nature, and pro-environmental behavior. Additionally, the nature group had a greater rate of change in connectedness to nature when compared to the control group. The results extend previous cross-sectional research by demonstrating the beneficial effects of meditation on pro-environmental behavior and its theorized mechanisms, which may be informative for future research and interventions.
Cross-Kingdom Cell-to-Cell Interactions in Cariogenic Biofilm Initiation

Published: August 2020

Candida albicans is known to form polymicrobial biofilms with various Streptococcus spp., including mitis and mutans group streptococci. Streptococcus gordonii (mitis group) has been shown to bind avidly to C. albicans hyphae via direct cell-to-cell interaction, while the cariogenic pathogen Streptococcus mutans (mutans group) interacts with the fungal cells via extracellular glucans. However, the biophysical properties of these cross-kingdom interactions at the single-cell level during the early stage of biofilm formation remain understudied. Here, we examined the binding forces between S. mutans (or S. gordonii) and C. albicans in the presence and absence of in situ glucans on the fungal surface using single-cell atomic force microscopy and their influence on biofilm initiation and subsequent development under cariogenic conditions. The data show that S. gordonii binding force to the C. albicans surface is significantly higher than that of S. mutans to the fungal surface (~2-fold). However, S. mutans binding forces are dramatically enhanced when the C. albicans cell surface is locally coated with extracellular glucans (~6-fold vs. uncoated C. albicans), which vastly exceeds the forces between S. gordonii and C. albicans. The enhanced binding affinity of S. mutans to glucan-coated C. albicans resulted in a larger structure during early biofilm initiation compared to S. gordonii–C. albicans biofilms. Ultimately, this resulted in S. mutans dominance composition in the 3-species biofilm model under cariogenic conditions. This study provides a novel biophysical aspect of Candida-streptococcal interaction whereby extracellular glucans may selectively favor S. mutans binding interactions with C. albicans during cariogenic biofilm development.
Trust and Communication With a Caregiver Reduces Behavior Problems and Protects Against Stress Among Urban Adolescents
Authors: Murphy Bridget , Franklin Marilyn , Tsang Yi Tak , Sala-Hamrick Kelsey , Atalla Mareena , Barnett Douglas
Published: August 2020

Youth, particularly urban minority youth, are exposed to high levels of stressful and potentially traumatic life events that have been linked to a wide array of negative outcomes including internalizing and externalizing problems. Youth perceptions of their interpersonal relationship quality with caregivers and friends were examined as potential promotive and protective factors counteracting the link between exposure to stressful and traumatic events and behavior problems. Participants were 85 urban, predominantly African American of age 13–17 years (60% girls). Results supported the hypothesis that youth report of parent trust and communication would serve as a promotive and protective factor, moderating the association between stressful life events and behavior problems. In contrast, peer trust and communication did not appear to counteract the association between stress and behavior problems. Instead, reports of trust and communication with friends appeared to increase the association between stress exposure and internalizing problems.

Published: August 2020

Telepractice coaching may be a viable alternative technology tool to deliver services to parents of children with autism spectrum disorder. Using a multiple probe design across participants, we examined the effectiveness of telepractice parent coaching in a communication intervention on parents’ implementation of strategies to improve their children’s communication skills. Project coaches instructed parents on strategies to teach communication skills to their child, including incentivizing communication, modeling, prompting, progressive time delay, and expanding. Results indicated a functional relation between the telepractice parent coaching intervention and parent use of strategies. Effect sizes for each participant are compatible with visual analysis results that show a very low effect to very strong effect depending on the intervention component examined.
What Type of School Leadership Makes Teachers Want to Stay?
Authors: Urick Angela
Published: August 2020

The purpose of this study is to identify different types of school leadership as perceived by teachers and to test the extent that these types predict teacher retention. School leadership varies by perception, context, and may influence a teacher’s decision to leave their current school or the profession. Four statistically different types of leadership were found using teachers’ perceptions of principal and shared leadership behaviors. Teachers who perceived less principal leadership were more likely to leave their school. Teachers who reported more frequent principal and shared leadership were more likely to stay in their current school the following year.
Improvements in patients with lipedema 4, 8 and 12 years after liposuction
Authors: Baumgartner Axel , Hueppe Michael , Meier-Vollrath Ilka , Schmeller Wilfried
Published: August 2020

Background

Long-term results following liposuction in patients with lipedema were available only for an average period of 8 years.

Objective

To find out whether the improvements persist for a further 4 years.

Methods

In 60 patients with lipedema a single-centre study with a mail questionnaire – often in combination with clinical controls – was performed after an average period of 12 years following liposuction(s). All patients in this group had already been surveyed 4 and 8 years after surgery.

Results

Compared with the earlier results improvement persisted with regard to spontaneous pain, sensitivity to pressure, edema, bruising and restriction of movement; similar outcomes were observed for self-assessment of cosmetic impairment, reduction in quality of life and overall impairment. While in the period from 4 to 8 years postoperatively complaints slightly increased, this was not the case for the period 8 to 12 years postoperatively. In addition a similar reduction of conservative treatment (decongestive therapy, compression garments) was observed as after 4 and 8 years postoperatively. Compared with the body weight before liposuction, 55% of the patients showed a reduction of 6.2 kg on average and 43.3% had a weight increase with an average of 7.9 kg.

Conclusion

The results show, that the positive effects of liposuction last 12 years postoperatively without relevant worsening. They imply that liposuction for lipedema leads to a permanent reduction of symptom severity and need for conservative therapy.

Authors: Mosquera-Rey Vicente , Del Castro Madrazo José A , Ángeles M Herrero María , Cordeu Rubén A , Azofra Ernesto A , Pérez Manuel A
Published: August 2020

Objective

the aim of this study was to assess the results of mechanochemical endovenous ablation either in the primary or recurrent saphenous vein insufficiency, including only patients with veno-venous shunt type III.

Methods

retrospective analysis of a prospective study of patients with symptomatic chronic venous insufficiency who underwent ClariVein® technique. A total of 134 saphenous veins were included between August 2017 and August 2018. Follow-up was performed by Duplex ultrasound at 1, 6 and 12 months. Primary endpoints were technical and anatomical success. Secondary endpoints were the need for further treatment of varicose collateral veins by sclerotherapy, outcomes regarding recurrent insufficiency and clinical success.

Results

A total of 111 great saphenous veins and 23 small saphenous veins were treated with a technical success of 95.6%. The overall anatomical success rates at 1, 6 and 12 month were 96.2%, 88.8% and 84.4%, respectively, without differences between primary and recurrent insufficiency. Deferred sclerotherapy over varicose collaterals was carried out in 28% of the patients with anatomical success. Clinical improvement was achieved in 87.3%.

Conclusions

MOCA technique has proven to be an effective technique, although additional treatment over varicose collaterals could be necessary in up to one-third. Atrophy of the saphenous vein and the lack of persistent varicose collateral veins during follow-up seem to be indicators of successful therapy.

Authors: Burrus Cyrille , Vuistiner Philippe , Léger Bertrand , Stiefel Friedrich , Rivier Gilles , Luthi François
Published: August 2020

Objective:

To use the self-assessment INTERMED questionnaire to determine the relationship between biopsychosocial complexity and healthcare and social costs of patients after orthopaedic trauma.

Design:

Secondary prospective analysis based on the validation study cohort of the self-assessment INTERMED questionnaire.

Setting:

Inpatients orthopaedic rehabilitation with vocational aspects.

Subjects:

In total, 136 patients with chronic pain and impairments were included in this study: mean (SD) age, 42.6 (10.7) years; 116 men, with moderate pain intensity (51/100); suffering from upper ( n = 55), lower-limb ( n = 51) or spine ( n = 30) pain after orthopaedic trauma; with minor or moderate injury severity (severe injury for 25).

Main measures:

Biopsychosocial complexity, assessed with the self-assessment INTERMED questionnaire, and other confounding variables collected prospectively during rehabilitation. Outcome measures (healthcare costs, loss of wage costs and time for fitness-to-work) were collected through insurance files after case settlements. Linear multiple regression models adjusted for age, gender, pain, trauma severity, education and employment contract were performed to measure the influence of biopsychosocial complexity on the three outcome variables.

Results:

High-cost patients were older (+3.6 years) and more anxious (9.0 vs 7.3 points at HADS-A), came later to rehabilitation (+105 days), and showed higher biopsychosocial complexity (+3.2 points). After adjustment, biopsychosocial complexity was significantly associated with healthcare (ß = 0.02; P = 0.003; expß = 1.02) and social costs (ß = 0.03; P = 0.006, expß = 1.03) and duration before fitness-to-work (ß = 0.04; P < 0.001, expß = 1.04).

Conclusion:

Biopsychosocial complexity assessed with the self-assessment INTERMED questionnaire is associated with higher healthcare and social costs.

Authors: Chen Fen-Qiao , Xu Wen-Zhong , Gao Hai-Yun , Wu Li-Juan , Zhang He , Cheng Li , Mei Jian-Qiang
Published: August 2020

Objective

To investigate Changweishu’s clinical effect on gastrointestinal dysfunction in patients with sepsis.

Methods

Fifty patients with gastrointestinal dysfunction and sepsis were randomly divided into treatment and control groups. The control group patients received routine Western medicine treatments (meropenem, noradrenaline, glutamine glue, Bifidobacterium lactis triple-strain tablet), and the treatment group patients received routine Western medicine treatment combined with Changweishu. Treatments in both groups lasted 7 days. Changes in APACHE II score, gastrointestinal dysfunction score, serum levels of diamine oxidase (DAO), D-lactic acid, inflammatory factors (tumor necrosis factor (TNF)-α, interleukin (IL)-6, and high-mobility group box 1 (HMGB-1)), and the incidence of multiple organ dysfunction syndrome (MODS) and mortality were observed.

Results

After treatment, APACHE II score, gastrointestinal dysfunction score, and DAO, D-lactic acid, TNF-α, IL-6, and HMGB-1 levels decreased significantly in both groups, but the decrease was more significant in the treatment group than in the control group. The incidence of MODS and mortality were significantly lower in the treatment group than in the control group.

Conclusion

The addition of Changweishu to routine Western treatments can improve gastrointestinal function in patients with sepsis and gastrointestinal dysfunction, as well as decreasing the incidence of MODS and mortality and improving patient prognosis.
Effect of Urban Rail Transit Lines Linking the New Towns on Land Value Uplift in the Megacity Based on Difference-in-Difference Model
Authors: Li Junfang , Liu Zhigang , Yu Jie , Hu Hua
Published: August 2020

There already exist some rail transit lines linking the new towns to the center business district (LTC) in megacities. However, few lines between the new towns (LTT) exist. The paper examines whether, when, and how LTT cause land value uplift with LTC as the benchmark, which in turn can be used for feasibility analysis for value capture financing for the implementation of LTT. Evaluate the value in catchment and control area over time to confirm uplift. Difference-in-difference model (DID) is used to analyze when and how LTT raise the uplift. In the case study of Tokyo, DID estimators show the following homogenous results: firstly, the implicit land value (ILV) of LTT is all lower than LTC except that related to time saving to the center business district (CBD) in the announcement period, implying LTT are expected significantly to link to CBD then; secondly, ILV goes down over time sharply for LTT than LTC, implying the impact of LTT on the uplift is less sustainable than that of LTC; thirdly, sustainability of ILV as to time saving to the capital of the new town is more than that to CBD for LTT; lastly, ILV in the announcement period presents significantly distance-decay performance for both lines. Heterogeneity among the stations is detected for both lines; for LTT, the impact of proximity to the huge interchange station on land value uplift is slight. These results provide an evidence base for policy-makers to quantify the potential to raise financial funding for LTT.
Estimating the Safety Effects of Congestion Warning Systems using Carriageway Aggregate Data
Authors: van Lint Hans , Nguyen Tin Thien , Krishnakumari Panchamy , Calvert Simeon. C. , Schuurman Henk , Schreuder Marco
Published: August 2020

Is it possible to use just aggregate carriageway data for the evaluation of congestion warning systems (CWS) in large networks—or any system affecting traffic safety for that matter? In this paper, two hypotheses related to this question are tested. The first hypothesis is that it can be done by comparing large-scale congestion patterns on road stretches with and without CWS. The underlying rationale is that heterogeneous congestion patterns with many disturbances, frequent wide moving jams, and large speed differences result in more potentially unsafe traffic conditions than more homogeneous congestion patterns. The second hypothesis is that it is possible to compare differences in average (maximum) deceleration distributions into congestion waves between road stretches with and without CWS. Both hypotheses have been tested for similar bottlenecks with similar demand patterns and the results suggest the first hypothesis must be rejected. Although the idea seems plausible (CWS result in more homogeneous congestion patterns) there were too many confounding factors in the data to make the case. However, persuasive evidence was found for the second hypothesis. Statistically significant differences were found between (maximum) deceleration distributions on road stretches with and without CWS that suggest CWS do—as expected—contribute positively to traffic safety. It thus seems to be possible to monitor safety effects using just average speeds. However, the method is limited to providing relative comparisons. Furthermore, to fully rule out the effects of unobserved factors, more evidence and validation with microscopic data are needed.
Mechanical Properties of Nano-Modified Cementitious Composites Reinforced with Single and Hybrid Fibers
Authors: Elhadary Riham , Bassuoni Mohamed T.
Published: August 2020

High-performance cementitious composites (HPCC) are prominently featured with high tensile ductility and toughness. Slag has been widely used in HPCC; however, HPCC with high volumes of slag has low matrix strength and limited development of micro-structure at early-age. These limitations can be mitigated by incorporating nano-particles (e.g., nano-silica) in the binder. The purpose of this study was to develop nano-modified HPCC with high ductility and matrix quality. A new form of basalt fibers termed basalt fiber pellets (BFP)—basalt fiber strands encapsulated by a polymeric resin—were used at different dosages (2.5% and 4.5% by volume), and in a hybrid system with PVA fibers (1% by volume) to develop in these composites. All composites incorporated a binder consisting of 50% general use cement and 50% slag with the addition of 6% nano-silica. The composites were tested in relation to compressive strength and flexural performance. All the nano-modified composites showed improved performance, especially at early-age, despite the high volume of slag incorporated in the binder. While the compressive strength of the mixtures was reduced with increasing the dosage of BFP, addition of 1% PVA fibers to BFP (hybrid system) enhanced the compressive strength of the composites. In the same context, the flexural performance of the composites comprising hybrid fibers was also improved in relation to flexural strength, post-cracking behavior, residual strength and toughness. Therefore, these composites have a promising potential for infrastructure applications requiring improved strength and ductility.
Psychometric Properties of the Behavior Assessment System for Children-3 Behavioral and Emotional Screening System Student-Report Form among a Predominantly Latinx Elementary School Sample
Authors: Dever Bridget V. , Gaier Kelsey
Published: August 2020

School-based universal screening for behavioral/emotional risk is a necessary first step in the identification of students who might need services within a behavioral response to intervention model. When choosing among the available screening measures, psychometric information such as reliability and validity of the scores is critical to inform such decisions. The purpose of the present study was to examine the reliability and validity of the Behavior Assessment System for Children (BASC)-3 Behavioral and Emotional Screening System (BESS) Student-report screening measure within a predominantly Latinx sample of 210 elementary school students. The proposed three-factor structure was generally upheld. The results supported adequate to strong test–retest reliability and internal consistency of both the overall score and the subscales (self-regulation, internalizing, and personal adjustment). Finally, the BASC-3 BESS Student also correlated to concurrent and future academic and behavioral outcomes, although the strength varied by domain.
Implementation of a Protocol Using the 5-Item Brief Alcohol Withdrawal Scale for Treatment of Severe Alcohol Withdrawal in Intensive Care Units
Authors: Rastegar Darius A. , Jarrell Andrew S. , Chen Edward S.
Published: August 2020

Background:

There is variation in the treatment of patients with severe alcohol withdrawal and a need for effective protocols. The purpose of this study was to evaluate the implementation of a symptom-triggered benzodiazepine protocol using the 5-item Brief Alcohol Withdrawal Scale (BAWS) for treatment of alcohol withdrawal in intensive care units (ICUs).

Methods:

This retrospective study included admissions to ICUs of 2 hospitals over 6 months who had an alcohol withdrawal protocol ordered and experienced severe withdrawal. Records were reviewed to collect demographic data, benzodiazepine exposure, duration of treatment, and withdrawal severity.

Results:

The protocol was ordered and implemented in 279 admissions; 48 (17.9%) had severe withdrawal defined as a BAWS of 6 or more. The majority of the 48 patients were from the emergency department (79.2%); mean hospital length of stay was 11.2 days and mean ICU stay 6.6 days; 31.3% required mechanical ventilation. A little more than half were treated only with the protocol (53.2%); 25.0% received additional benzodiazepines, 20.8% dexmedetomidine, 10.4% propofol, 25.0% antipsychotics and 2.0% phenobarbital.

Conclusion:

Among ICU patients treated for alcohol withdrawal with a symptom-triggered benzodiazepine protocol using a novel 5-item scale, most did not develop severe withdrawal, and of those who did, approximately half were treated with the protocol alone.
Tooth crest chamfering method of spiral bevel gear using ball end milling cutter
Authors: Wei Wei , Li Zhe , Tan Rao
Published: August 2020

A chamfering method is proposed in order to improve processing accuracy and efficiency of tooth crest chamfering of spiral bevel gear. Coordinates of discrete points of upper and lower edges of chamfering surface are calculated based on the mathematical model of tooth surface and face cone. Distances between center of ball end milling cutter and upper and lower edges are set equal to radius of the ball end milling cutter, chamfering tool path is generated by particle swarm algorithm solving, both sides of tooth crest can be chamfered simultaneously to ensure processing efficiency. Direction angle of the cutter axis is calculated based on the relationship between direction of the cutter axis and contact positions of the cutter surface. Aiming to prolong service life of cutter, direction angle varies uniformly within the feasible region and contact positions distribute evenly on the cutter surface. Pinion without tooth crest chamfering is installed on four-axis CNC machine tools, edge detector is used to detect axial and circumferential cutter positions, then chamfering experiment is completed. Widths of chamfering surface are measured on different measuring positions, maximum error is 0.08 mm compared with design width 1 mm which appears at tooth crest inner end of convex side. Measuring results show that chamfering error is much smaller than that with manual chamfering, which indicates that the chamfering method is feasible.
Effect of rolling parameters on forming quality of flat cross wedge rolling thread shafts
Authors: Shao YiYu , Peng WenFei , Yu Xuan , Oleksandr Moliar , Titov Vyacheslav
Published: August 2020

The flat cross wedge rolling is an advanced forming process, which is used to produce thread shafts. In this work, a finite element model of flat cross wedge rolling thread shafts was established by the DEFORM-3D, and the effect of the forming angle, spreading angle, helix angle and flank angle on forming quality are investigated. The research results show that the forming angle, spreading angle, helix angle have a significant influence on the position of the die wedge-in point. The angle designed wrongly makes the die wedge-in point unable to be aligned correctly, causing defects such as slipping in the process, repeated rolling of formed thread, thin or incomplete tooth shapes. The flank angle mainly makes an impact on the axial force. Reducing the right flank angle or increasing the left flank angle can effectively improve the imbalance of axial force to obtain high-quality thread shafts. Through the experiment of flat cross wedge rolling thread shafts, the data comparison demonstrates that the error of the external dimension of formed parts is small, proving the reliability of the rolling parameter selection.
The summit of a moral pilgrimage: Confucianism on healthy ageing and social eldercare
Authors: Nie Jing-Bao
Published: August 2020

To effectively address ageing and develop adequate eldercare needs, among others, new ethical visions are much needed. One of the ways to formulate sound ethical visions for contemporary issues is to reclaim, reinterpret and revive old moral ideas and ideals rooted in different indigenous cultural traditions. Drawing thought, wisdom and inspirations from classical Confucianism, the article offers a Confucian ethical outlook on healthy ageing and social eldercare. The popular perception of ageing in the West as well as China regards old age as a period of inevitable decline. However, Kong Zi (Confucius) treats human life as an ongoing moral pilgrimage, with old age the summit of the lifelong journey. This Confucian ethical view on ageing as the culmination of a lifelong moral cultivation has various important themes. They include the primary feature of learning in healthy ageing, the essential role of social eldercare embedded in the popular Confucian norm ‘filial piety’ ( xiao), intergenerational flourishing and the necessity to respect the rights and dignity of each old person. Such a Confucian socio-ethical vision can not only help identify contemporary failings in the area of eldercare but also generate novel ideas and frameworks to help China and the world to face population ageing and elderly care in a more positive way.

Background:

The aim of this study is to assess the effect of nasoalveolar molding (NAM) versus no-NAM on nasal morphology in patients with unilateral cleft lip and palate (UCLP) at the time of nasal maturity.

Methods:

A retrospective, single-institution review was conducted on all non-syndromic patients with UCLP. Inclusion criteria included age 14 years or above, unilateral cleft repair at the time of infancy, and adequate photography taken at nasal maturity and prior to rhinoplasty. Exclusion criteria included age less than 14 years, syndromic diagnosis, and rhinoplasty prior to nasal maturity. Ten parameters were measured twice from standardized clinical photographs using the Dolphin Imaging Software for establishment of intrarater reliability. Subjective analysis was achieved through completion of the Asher McDade grading scale by 3 expert cleft practitioners.

Results:

Nostril height, columellar angle, alar cant, vertical alar height, alar height angle, nasofacial angle, and nasolabial angle were found to be significantly less severe in patients who had undergone NAM in conjunction with surgical repair when compared with those who had undergone surgical repair alone. Asher McDade grading revealed significant improvement in nasal form, nasal symmetry/deviation, nasal profile, vermillion border, and overall score in patients who underwent NAM compared to no-NAM.

Conclusion:

The use of presurgical NAM during infancy can improve nasal symmetry and nasal proportions at the time of nasal maturity.
The Influence of Self-Compassion on Mindful Parenting: A Mediation Model of Gratitude
Authors: Nguyen Thanh Minh , Bui Thi Thuy Hang , Xiao Xingxue , Le Vu Ha
Published: August 2020

Mindful parenting, a concept that has been coined and examined recently, refers to a parent’s ability to bring complete attention to their children in the present moment. The aims of this study are to examine the relationship between self-compassion and mindful parenting and the role of gratitude as a mediating variable in a cross-sectional study. Participants include 522 Vietnamese mothers ( M age = 35.17; SD = 5.56) randomly selected through an online investigation. A 26-item Self-Compassion Scale was used to measure self-compassion, gratitude was measured by the Gratitude Questionnaire Six-Item Form, and mindful parenting was measured by the Interpersonal Mindfulness in Parenting Scale. The results support two main findings: (a) self-compassion has a direct influence on mindful parenting (effect = 2.48, p < .001, 95% CI [1.75, 3.22]), and (b) the mediating role of gratitude in this model was significant (effect = 0.37, 95% CI [0.10, 0.70]). The study’s results also show that increasing self-compassion and gratitude can help to improve mindful parenting.

Recommendation:

Progressive collapsing foot deformity (PCFD) is a complex 3D deformity with varying degrees of hindfoot valgus, forefoot abduction, and midfoot supination. Although a medial displacement calcaneal osteotomy can correct heel valgus, it has far less ability to correct forefoot abduction. More severe forefoot abduction, most frequently measured preoperatively by assessing talonavicular coverage on an anteroposterior (AP) weightbearing conventional radiographic view of the foot, can be more effectively corrected with a lateral column lengthening procedure than by other osteotomies in the foot. Care must be taken intraoperatively to not overcorrect the deformity by restricting passive eversion of the subtalar joint or causing adduction at the talonavicular joint on simulated AP weightbearing fluoroscopic imaging. Overcorrection can lead to lateral column overload with persistent lateral midfoot pain. The typical amount of lengthening of the lateral column is between 5 and 10 mm.

Level of Evidence:

Level V, consensus, expert opinion.

CONSENSUS STATEMENT ONE:

Lateral column lengthening (LCL) procedure is recommended when the amount of talonavicular joint uncoverage is above 40%. The amount of lengthening needed in the lateral column should be judged intraoperatively by the amount of correction of the uncoverage and by adequate residual passive eversion range of motion of the subtalar joint. Delegate vote: agree, 78% (7/9); disagree, 11% (1/9); abstain, 11% (1/9). (Strong consensus)

CONSENSUS STATEMENT TWO:

When titrating the amount of correction of abduction deformity intraoperatively, the presence of adduction at the talonavicular joint on simulated weightbearing fluoroscopic imaging is an important sign of hypercorrection and higher risk for lateral column overload. Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%. (Unanimous, strongest consensus)

CONSENSUS STATEMENT THREE:

The typical range for performing a lateral column lengthening is between 5 and 10 mm to achieve an adequate amount of talonavicular coverage. Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%. (Unanimous, strongest consensus)
Consensus for the Use of Weightbearing CT in the Assessment of Progressive Collapsing Foot Deformity

Published: August 2020

Recommendation:

There is evidence that the use of WEIGHTBEARING imaging aids in the assessment of progressive collapsing foot deformity (PCFD). The following WEIGHTBEARING conventional radiographs (CRs) are necessary in the assessment of PCFD patients: anteroposterior (AP) foot, AP or mortise ankle, and lateral foot. If available, a hindfoot alignment view is strongly recommended. If available, WEIGHTBEARING computed tomography (CT) is strongly recommended for surgical planning. When WEIGHTBEARING CT is obtained, important findings to be assessed are sinus tarsi impingement, subfibular impingement, increased valgus inclination of the posterior facet of the subtalar joint, and subluxation of the subtalar joint at the posterior and/or middle facet.

Level of Evidence:

Level V, consensus, expert opinion.

Published: August 2020

Introduction

Carcinogenesis is driven by an array of complex genomic patterns; these patterns can render an individual resistant or sensitive to certain chemotherapy agents. The Personalized Oncogenomics (POG) project at BC Cancer has performed integrative genomic analysis of whole tumour genomes and transcriptomes for over 700 patients with advanced cancers, with an aim to predict therapeutic sensitivities. The aim of this study was to utilize the POG genomic data to evaluate a discrete set of biomarkers associated with chemo-sensitivity or-resistance in advanced stage breast and colorectal cancer POG patients.

Methods

This was a retrospective multi-centre analysis across all BC CANCER sites. All breast and colorectal cancer patients enrolled in the POG program between July 1, 2012 and November 30, 2016 were eligible for inclusion. Within the breast cancer population, those treated with capecitabine, paclitaxel, and everolimus were analyzed, and for the colorectal cancer patients, those treated with capecitabine, bevacizumab, irinotecan, and oxaliplatin were analyzed. The expression levels of the selected biomarkers of interest ( EPHB4, FIGF, CD133, DICER1, DPYD, TYMP, TYMS, TAP1, TOP1, CKDN1A, ERCC1, GSTP1, BRCA1, PTEN, ABCB1, TLE3, and TXNDC17) were reported as mRNA percentiles.

Results

For the breast cancer population, there were 32 patients in the capecitabine cohort, 15 in the everolimus cohort, and 12 in the paclitaxel cohort. For the colorectal cancer population, there were 29 patients in the bevacizumab cohort, 12 in the oxaliplatin cohort, 29 in the irinotecan cohort, and 6 in the capecitabine cohort. Of the biomarkers evaluated, the strongest associations were found between Bevacizumab-based therapy and DICER1 (P = 0.0445); and between capecitabine therapy and TYMP (P = 0.0553).

Conclusions

Among breast cancer patients, higher TYMP expression was associated with sensitivity to capecitabine. Among colorectal cancer patients, higher DICER1 expression was associated with sensitivity to bevacizumab-based therapy. This study supports further assessment of the potential predictive value of mRNA expression of these genomic biomarkers.
Is Male Adolescents’ Sexual Aggressiveness Better Explained by Prior Pornography Use or Callousness? A Brief Report
Authors: Štulhofer Aleksandar
Published: August 2020

To address growing concerns about the role of pornography use in adolescents’ sexual socialization, we explored the role of callousness, relative to pornography use, in male adolescents’ self-reported sexual aggressiveness. Two competing conceptualizations of this role were tested using data from a larger longitudinal research project on sexualized media use and adolescent well-being. Considering that callousness was assessed at only two waves (T2 and T4), 381 male Croatian adolescents ( Mage = 15.88, SD = 0.49) who participated in both waves were included in the study. Generalized mixed effects regression modeling indicated that callousness, but not pornography use, significantly predicted sexual aggressiveness 11 months later. Callousness also moderated the association between pornography use and sexual aggressiveness, so that among participants who scored high in callousness, more frequent pornography use was related to lower odds of reporting sexual aggressiveness. High callousness is a risk factor for male adolescents’ sexual aggression and should be addressed in prevention programs.

Bread is a staple food for majority of the people worldwide, but it has a high glycemic effect. Substituting wheat flour partly with chickpea flour and the presence of bran is suggested to improve the glycemic effect of bread; however, the non-gluten substances in wheat flour adversely affect dough rheology. The addition of amla powder was tested on the rheological properties of wheat–chickpea flour composite doughs; also, the physical and sensory qualities of bread made thereof. The results showed that when the level of replacement of refined white flour (WF) or whole wheat flour (WWF) with chickpea flour was increased from 0 to 40%, it significantly affected the rheological properties and functionality of dough. A decreased farinograph water absorption, higher mixing tolerance index (i.e., weakening of dough), decreased resistance to extension, and lower ratio numbers were obtained with some differences between WF and WWF at the higher level of chickpea flour substitution. The addition of amla powder to WF: chickpea flour (60:40) blends reduced the angle of ascending (from 7.0 ± 0.7 to 6.0 ± 0.7) and angel of descending (from 3.2 ± 0.21 to 2.4 ± 0.2), indicating the slight tightening of gluten leading to dough breakdown. The addition of amla powder improved the mixing characteristics of the composite flour doughs, as well as the physical and sensory qualities of the bread. In conclusion, amla powder can help overcome the deleterious impact of adding chickpea flour to WF or WWF for producing good quality pan bread for people with type-2 diabetes.
