Introduction:Professional dancers are committed to dancing despite their injuries and mood changes. Therefore, dancers’ balance ability should be evaluated as an objective indicator of the quality of their dance/dancing ability.Objective:We aimed to examine the relationship between the balance ability of professional ballet dancers and their psychological traits and states by serotonin polymorphism, using pressure and center of gravity sensors.Methods:Five female professional dancers participated in this three-month longitudinal pilot study. The dancers’ stress status was assessed each month on three conditional days to gauge stress conditions. Before and after their standard warm-up exercises, the dancers’ center of gravity was assessed while standing and posing in ballet-specific positions, and psychological questionnaire surveys were conducted to assess the level of anxiety and objective stress. After all observations were completed, serotonin polymorphism was analyzed as one of the psychological traits.Results:All participants possessed the s/s-type (short type) serotonin transporter gene promoter polymorphism, indicating high sensitivity to stress. Their average trait anxiety score was 50.80±8.47. However, all participants were able to be calm, had no injuries, and maintained a stable center of gravity throughout the study period.Conclusion:Throughout the study, from ordinary practice to the time of the approaching ballet performance, the participants maintained stable balance ability regardless of their psychological traits and states of mind. It is unlikely that reactions to stress and psychological traits affected professional dancers’ physicality. Thus, continuous assessment of the balance between mental and physical aspects enhances performance management.

Published: October 2022

Background
Earable devices are novel, wearable Internet of Things devices that are user-friendly and have potential applications in mobile health care. The position of the ear is advantageous for assessing vital status and detecting diseases through reliable and comfortable sensing devices.

Objective
Our study aimed to review the utility of health-related indicators derived from earable devices and propose an improved definition of disease prevention. We also proposed future directions for research on the health care applications of earable devices.

Methods
A systematic review was conducted of the PubMed, Embase, and Web of Science databases. Keywords were used to identify studies on earable devices published between 2015 and 2020. The earable devices were described in terms of target health outcomes, biomarkers, sensor types and positions, and their utility for disease prevention.

Results
A total of 51 articles met the inclusion criteria and were reviewed, and the frequency of 5 health-related characteristics of earable devices was described. The most frequent target health outcomes were diet-related outcomes (9/51, 18%), brain status (7/51, 14%), and cardiovascular disease (CVD) and central nervous system disease (5/51, 10% each). The most frequent biomarkers were electroencephalography (11/51, 22%), body movements (6/51, 12%), and body temperature (5/51, 10%). As for sensor types and sensor positions, electrical sensors (19/51, 37%) and the ear canal (26/51, 51%) were the most common, respectively. Moreover, the most frequent prevention stages were secondary prevention (35/51, 69%), primary prevention (12/51, 24%), and tertiary prevention (4/51, 8%). Combinations of ≥2 target health outcomes were the most frequent in secondary prevention (8/35, 23%) followed by brain status and CVD (5/35, 14% each) and by central nervous system disease and head injury (4/35, 11% each).

Conclusions
Earable devices can provide biomarkers for various health outcomes. Brain status, healthy diet status, and CVDs were the most frequently targeted outcomes among the studies. Earable devices were mostly used for secondary prevention via monitoring of health or disease status. The potential utility of earable devices for primary and tertiary prevention needs to be investigated further. Earable devices connected to smartphones or tablets through cloud servers will guarantee user access to personal health information and facilitate comfortable wearing.
The Development and Evaluation of “Life Age”—a Primary Prevention and Population-Focused Risk Communication Tool: Feasibility Study With a Single-Arm Repeated Measures Design
Authors: Olusan Adeogo Akinwale , Barr Suzanne , Cobain Mark , Whelan Holly 
Published: October 2022

Background
Communicating cardiovascular risk to the general population requires forms of communication that can enhance risk perception and stimulate lifestyle changes associated with reduced cardiovascular risk.

Objective
The aim of this study was to evaluate the motivational potential of a novel lifestyle risk assessment (“Life Age”) based on factors predictive of both premature mortality and psychosocial well-being.

Methods
A feasibility study with a single-arm repeated measures design was conducted to evaluate the potential efficacy of Life Age on motivating lifestyle changes. Participants were recruited via social media, completed a web-based version of the Life Age questionnaire at baseline and at follow-up (8 weeks), and received 23 e-newsletters based on their Life Age results along with a mobile tracker. Participants’ estimated Life Age scores were analyzed for evidence of lifestyle changes made. Quantitative feedback of participants was also assessed.

Results
In total, 18 of 27 participants completed the two Life Age tests. The median baseline Life Age was 1 year older than chronological age, which was reduced to –1.9 years at follow-up, representing an improvement of 2.9 years (P=.02). There were also accompanying improvements in Mediterranean diet score (P=.001), life satisfaction (P=.003), and sleep (P=.05). Quantitative feedback assessment indicated that the Life Age tool was easy to understand, helpful, and motivating.

Conclusions
This study demonstrated the potential benefit of a novel Life Age tool in generating a broad set of lifestyle changes known to be associated with clinical risk factors, similar to “Heart Age.” This was achieved without the recourse to expensive biomarker tests. However, the results from this study suggest that the motivated lifestyle changes improved both healthy lifestyle risks and psychosocial well-being, consistent with the approach of Life Age in merging the importance of a healthy lifestyle and psychosocial well-being. Further evaluation using a larger randomized controlled trial is required to fully evaluate the impact of the Life Age tool on lifestyle changes, cardiovascular disease prevention, and overall psychosocial well-being.

Orthodontic treatment protocols in patients with alveolar clefting: a survey of ACPA–approved cleft teams in the United States
Authors: Preston Kathryn , Chen Lucia , Brennan Tyler , Sheller Barbara 
Published: October 2022

ABSTRACT

Objectives
To describe pre– and post–alveolar bone graft (ABG) practice protocols of orthodontists associated with American Cleft Palate-Craniofacial Association–approved cleft and cleft/craniofacial teams.

Materials and Methods
Electronic survey responses from team orthodontists were evaluated regarding pre-ABG orthodontic treatment type(s), timing of post-ABG imaging and post-ABG orthodontic treatment, and craniofacial orthodontic fellowship training status of the team orthodontists. A P value of &lt;.05 was considered significant.

Results
Of 31 responding orthodontists, 54.8% had fellowship training and 45.2% did not. Pre-ABG orthodontic preparation ranged from solely maxillary expansion for alveolar segment alignment (35.5%) to a combination of maxillary expansion for both alveolar segment alignment and posterior crossbite correction, anterior tooth alignment, and anterior crossbite correction (19.4%). Most captured post-ABG radiographs prior to orthodontic tooth movement (90.3%). Orthodontists began treatment at least 6 months (35.5%), 2–4 months (32.3%), or 4–6 months (29%) post-ABG. No significant differences were found when comparing fellowship subgroups. In addition, 47.1% of fellowship-trained orthodontists deferred post-ABG orthodontic treatment to at least 6 months post-operatively, vs 21.4% of non–fellowship trained orthodontists (P = .14).

Conclusions
A large variation in approaches is evident in pre-ABG orthodontic treatment types and timing of post-ABG treatment. Post-operative imaging is pursued by most orthodontists to assess graft status prior to initiating orthodontic treatment. Additional clinical research is needed to support providers in their decision-making with regard to evidence-based approaches.

Published: October 2022

Preparation of cassava seeds using a machete or hand saw takes a long time, the results are not uniform, and there is a potential for damage to cassava seedlings. The double block cutter type cassava stem cutting machine has been designed to produce high capacity and good quality cassava seeds. This study aims to test the performance of the cassava stem cutting machine with the double block cutter type. Performance tests include measuring machine working capacity, fuel consumption, seed uniformity, and planting test. The cutting test was carried out using 3 varieties of cassava seedlings. The machine works at a rotational speed of 3800 rpm and the test was carried out with various feeding loads, namely 3 rods, 4 rods, and 5 rods with. Each test was repeated 3 times. Cassava stem cutting machine (Petokong) is suitable for producing cassava stems with an average working capacity of 16275 seeds/hour. The results of the Anova test showed that the number of baits and varieties of cassava seeds and their interaction had a significant effect on the working capacity of the Petokong machine. Variations in fuel consumption are thought to be influenced by the variety of cassava stem used, which is influenced by the stem diameter of each variety. The Petokong machine is far superior to manual cutting using a machete or saw which can only produce 815 and 3005 seeds/hour per hour. The average fuel consumption is 1.82 liters per hour. Seed uniformity is about 98% and seedling damage can be minimized to 2%. The seeds produced by the Petokong machine can grow well, which is indicated by the appearance of shoots and an even distribution of roots.

Prenatal and perinatal phthalate exposure is associated with sex-dependent changes in hippocampal miR-15b-5p and miR-34a-5p expression and changes in testicular morphology in rat offspring
Authors: Štefánik Peter , Michalec Jaroslav , Morová Martina , Olexová Lucia , Kršková Lucia 
Published: October 2022

Abstract
MicroRNAs are a large group of non-coding nucleic acids, usually 20–22 nt long, which bind to regulatory sections of messenger RNA (mRNA) and inhibit gene expression. However, genome activity is also regulated by hormones. Endocrine disruptors such as those from the phthalate group imitate or block these hormonal effects, and our previous study showed a long-lasting decrease in plasma testosterone levels in rat offspring exposed to a mixture of three phthalates in utero and postnatally. These effects were also observed at the behavioural level. To shed more light on these findings, in this new study we compared testicular tissue morphology between control and phthalatetreated males and investigated possible persistent changes and sex differences in the expression of two hippocampal microRNAs – miR- 15b-5p and miR-34a-5p – participating in the transcription of steroidogenic genes. Histologically observed changes in testicular tissue morphology of phthalate-exposed males compared to control support testosterone drop observed in the previous study. At the microRNA level, we observed more significant changes in phthalate-treated females than in males. However, we are unable to relate these effects to the previously observed behavioural changes.

Published: October 2022

Abstract

Introduction: Psoriasis is a chronic, common immune inflammatory condition of the skin, affecting 2-3% of the population, with regional variability. Classically, psoriasis presents as one of the following types: plaque, guttate, inverse, pustular or erythrodermic psoriasis. Typically, the patient will present with several symmetric psoriatic plaques on typical areas of the body, leading the clinician towards the diagnosis of psoriasis.

Case report: The present case report series focuses on an atypical presentation of psoriasis noted in 2 patients who presented to our office with a single large, erythematous plaque located on the lower leg. Due to poor response to previous treatment, a biopsy was performed and upon analysis, revealed a diagnosis of psoriasis. The lesions showed significant improvement under local therapy.

Conclusion: In spite of significant research on such a common and seemingly well-understood dermatosis, the present case reports plead for further study with regards to atypical presentations of psoriasis.

Authors: Shetty Preethesh , Bhat Raksha , Kini Arjun 
Published: October 2022

Abstract
The trauma of anterior teeth is a frequent occurrence in young patients. Reattachment of fractured fragments is one of the various treatment modalities proposed in anterior tooth coronal fractures. The reattachment of fractured fragments grants the advantage of immediate aesthetic rehabilitation and restoration of function, which is a relatively rapid and less arduous procedure. The manuscript presents a case report depicting the management of a complicated crown root fracture of anterior maxillary teeth first treated endodontically, followed by reattachment of the same fragment with a cast post-reinforcement. Reattachment of fractured coronal tooth fragments is a feasible restorative option, rapidly restoring the function and aesthetics of the tooth by a conservative and inexpensive approach.
The Approximate Solution of Nonlinear Vibration of Tennis Based on Nonlinear Vibration Differential Equation
Authors: Jia Xiaoqiang 
Published: October 2022

Abstract
In this paper, a nonlinear vibration differential equation is established for the moment when a tennis racket hits the ball. At the same time, we deduce the relationship between the tennis racket string tension and the separation time and distance of the hitting speed. Then the article analyzes the vibration equation of the tennis racket damping ball. We use ANSYS finite element analysis software for solid modeling and modal analysis of tennis rackets. The natural frequency of the tennis racket was obtained through the verification results of the experimental modal analysis. A qualitative relationship between the natural frequency of the vibration-absorbing ball system and some parameters was found.

Published: October 2022

Abstract
The Couffo basin is not well known, and neither are its aquatic living resources, such as fish fauna, which are subjected to high exploitation rates. The objectives of this study were to establish length-weight ratios (LWRs) and length-length ratios (LLRs) for the most important species in the catches and those of certain economic value. A total of 12,191 specimens belonging to 40 commercial species of actinopterygian fishes were caught with several fishing gears and methods between February 2018 and March 2021. Allometric coefficient b of the LWRs (BW = a × TL
b
) ranged from 2.194 for Enteromius callipterus to 3.673 for Protopterus annectens with a mean of 2.902 ± 0.315. The growth of thirteen species was isometric, that of fourteen species was negatively allometric, and that of the remaining thirteen species was positively allometric. Coefficient of determination r2
for the LLRs of 39 of the 40 selected species mentioned above was significant and ranged from 0.781 in Gobionellus occidentalis to 0.997 in Elops senegalensis with a mean value of 0.951 ± 0.049. The results will be useful for further studies on assessments of population dynamics and the sustainable conservation of the already limited fish stocks in the Couffo River basin.

Abstract
Settlement of unintended deviation between scheduled and realized energy exchange among LFC (Load Frequency Control) areas used to be conducted through the energy compensation programs, where energy deviation from period of registration is compensated at a later stage period of compensation of unintended deviation. With the adoption of the Synchronous Area Framework Agreement (SAFA), the Regional Group for Continental Europe the methodology of accounting and financial settlement of unintended deviations FSKAR (Financial settlement kΔf, ACE and ramping period) is defined. The FSKAR methodology defines necessary data for the calculation and determination of unintended deviation. The methodology defines the method of determining settlement prices. The paper describes the methodology of determining settlement prices, the method of data collection and validation, the method of calculation of deviations and other energy and financial quantities, and data exchange between entities.
