Authors: Karataş Zeki , Tüccar Esin
Published: April 2024

Natural disasters such as earthquakes have a profound effect on the psychological well-being of individuals affected by earthquakes. The purpose of this study is to examine the relationship between post-earthquake trauma levels and spiritual well-being and various sociodemographic variables of individuals affected by the earthquake in Turkey on 6 February 2023. Relational survey model of quantitative research method was used in the study. The sample of the study consists of 440 participants who were reached by convenience sampling technique from earthquake survivors in 11 provinces in Turkey who experienced the earthquake centred in Pazarcık District of Kahramanmaraş Province in Turkey. The Scale for Determining the Level of Post-Earthquake Trauma, Spiritual Well-Being Scale, and Sociodemographic Information Form were used as data collection tools in the study. The data obtained were analysed using one-way analysis of variance, t-test and simple regression analysis. As a result of the study, it was determined that there was a low level, negative and significant relationship between the participants' post-earthquake trauma levels and their spiritual well-being. While there was no significant difference in terms of post-earthquake trauma level between the groups with different residence, education level, and frequency of religious beliefs, a significant difference was found between the post-earthquake trauma level and variables such as gender, age, loss of relatives in the earthquake, perceived economic status, and damage status of the house. The findings provide valuable information on the importance of spiritual well-being in alleviating post-earthquake trauma and emphasise the potential of including spiritual support in disaster management and mental health interventions.

Published: April 2024

The chemical reaction of heat and mass transfer in an unsteady magnetohydrodynamics (MHD) mixed convection stagnation point flow towards a vertical stretching plate embedded in porous medium was studied. Richardson number and concentration were taken into consideration in this study. By selecting suitable similarity variables, the non-linear partial differential equations (PDEs) are transformed into a set of ordinary differential equations (ODEs), and then solved numerically using the boundary value problem solver (bvp4c) in MATLAB software. The solution is dependent on the governing parameters including Prandtl number, reaction rate parameter, Schmidt number, thermal Richardson number and buoyancy ratio parameter. The numerical results are depicted graphically in velocity, temperature and concentration profiles. The findings have shown that as the chemical reaction parameter increases, the temperature profile and Sherwood number also increases.

Authors: Nur Amira Syahirah Azmar  , Raja Noor Farah Azura Raja Ma'amor Shah
Published: April 2024

Photovoltaic electric vehicle charging stations (PEVCS) has been highlighted as an inspiration for sustainable mobility due to its environmental friendliness, ability to reduce transportation issues and potential to improve air quality. The establishment of PEVCS networks along major routes is projected to significant increase EV adoption in Malaysia, reducing EV customers' range anxiety. Given the current deployment of several electric vehicle charging stations (EVCS) and a limited number of PEVCS in Malaysia, there is a compelling reason for increasing the quantity of PEVCS along routes to magnify its positive environmental impact. Adding to the previously described problems, this study seeks to identify suitable locations for PEVCS in Malaysia. The findings of the Need Analysis completed as part of this study were used to develop these site-selection criteria, which include both main and secondary factors. Finally, 41 sub-criteria were chosen for this study, which are divided into the following categories: society, economy, environment, technology, accessibility and proximity. In conclusion, these criteria provide a comprehensive framework for decision-makers and stakeholders to determine suitable spots for PEVCS in Malaysia, supporting sustainable mobility and improving the entire experience for electric vehicle users.
Human Perception of Emotions from Canis familiaris Barks: An Auditory-Perceptual Study
Authors: Singh Varun , Saroj Winston Jim
Published: April 2024

This study investigates how experience and gender influence the perception of emotions in dog barks. Drawing from Morton's structural-motivational rule and previous research on mammalian vocalizations, we aimed to discern whether humans, especially those experienced with dogs, can accurately identify emotions such as stranger, anger, lonely, and play in dog barks. Using recordings of Indian Lesser Spitz barks in various contexts, we conducted auditory-perceptual experiments with two groups: experienced listeners (with more than 2- 3 years of pet dog experience) and non-experienced listeners. Participants listened to bark sequences and identified the corresponding emotions. Results revealed that experienced listeners consistently outperformed non- experienced ones in identifying emotions, except for 'play,' where no significant difference was observed. Gender did not significantly affect emotion perception. Interestingly, 'anger' was most accurately identified across both groups, followed by 'stranger,' 'play,' and 'lonely' emotions. Analyzing open-ended responses, we found that acoustic cues such as pitch and inter-bark intervals strongly influenced emotional perception. 'Stranger' barks were described as low-pitched, while 'anger' barks had shorter inter-bark intervals. 'Lonely' barks were characterized by high pitch and longer inter- bark intervals than 'play' barks. These findings suggest that experience plays a crucial role in accurately perceiving emotions in dog barks, aligning with the concept of a common mammalian heritage in emotional communication. Gender differences were negligible in this context. Understanding the acoustic cues underlying emotional expression in dogs enhances our comprehension of canine behavior and has implications for fields like animal welfare and neuroscience. Further research could delve deeper into the mechanisms underlying emotional perception in non-verbal communication across mammalian species.

The challenges encountered in aquatic communication systems encompass colourful factors, including limited bandwidth, high energy consumption rates, extended propagation detention times, End- to- End Delay(E-ED), media access control, routing complications, resource application, and power constraints. These challenges bear the perpetration of energy-effective protocols, which can be distributed into localization- grounded or localization-free protocols. This design primarily focuses on reviewing and assaying localization-free protocols, considering environmental variables, data transmission rates, transmission effectiveness, energy consumption rates, E-ED, and propagation detainments. Through a comprehensive review, the design aims to identify the strengths and sins of being protocols, thereby paving the way for unborn advancements in Aquatic Wireless Sensor Networks (UWSNs). The proposed check entails an in- depth examination of localization-free protocols, pressing the specific problems addressed and the crucial parameters considered during routing in UWSNs. Unlike former checks, this study concentrates on the current state- of- the- art routing protocols, emphasizing the routing strategy issues they attack. By emphasizing the advantages of each protocol, the design seeks to decide energy-effective results. likewise, detailed descriptions of the routing strategies employed by each protocol are handed to enhance appreciation. also, the downsides of each protocol are strictly examined to grease farther disquisition and identify the most suitable protocol. The comprehensive analysis of routing strategies, along with the delineation of pros and cons, not only sheds light on being challenges but also offers precious perceptivity into unborn exploration directions. By presenting open challenges and delineating implicit exploration avenues, this design aims to contribute to the ongoing elaboration and enhancement of aquatic communication systems.

Authors: Saha S.N.
Published: April 2024

The US and India are different in various socioeconomic aspects. Still the inflation are rates between them showed moderately correlated in respected in respect of food prices 2022. Both countries adopted necessary measures to supply food and beverages in the lockdown and related bottlenecks in order to check the rapidly rising commodity prices. But still the food prices increased continuously almost in the whole year,2022. Food and fuel have been said the drivers of inflation during the Covid-19 pandemic period (Philip Barrett Sep,12,2022). The world itself was partially a closed economy as foreign trade dwindled to a large extent. So countries had to depend mostly on indigenous production and market supply network. But as the food and beverage demand, it is dependent on economic factors like testes, habits and preference of the households. These factors played important role in the head line inflation in different countries during Covit-19 pandemic. The present study is an attempt to highlight the complex factors such as food habits ,tastes and preferences in the US and India. This shows how the said factors impacted upon the food inflation in them.

A Weierstrass Representation Formula for Discrete Harmonic Surfaces
Authors:   Tohoku University, Japan, Kotani Motoko , Naito Hisashi ,   Nagoya University, Japan
Published: April 2024

A discrete harmonic surface is a trivalent graph which satisfies the balancing condition in the 3-dimensional Euclidean space and achieves energy minimizing under local deformations. Given a topological trivalent graph, a holomorphic function, and an associated discrete holomorphic quadratic form, a version of the Weierstrass representation formula for discrete harmonic surfaces in the 3-dimensional Euclidean space is proposed. By using the formula, a smooth converging sequence of discrete harmonic surfaces is constructed, and its limit is a classical minimal surface defined with the same holomorphic data. As an application, we have a discrete approximation of the Enneper surface.
ON WHICH SOCIOECONOMIC GROUPS DO REVERSE MORTGAGES HAVE THE GREATEST IMPACT? EVIDENCE FROM SPAIN
Authors: Boj Eva , Claramunt M. Mercè , Varea Xavier
Published: April 2024

Reverse mortgage is one of the products (perhaps the main one) that is good to obtain additional income by using the habitual residence as collateral. The main objective of this paper is to analyse the effects that reverse mortgage contracting has on household finances over the lifetime of a family according to the socioeconomic group to which it belongs in Spain. Four indicators are employed to measure the immediate and long-term effects. We use a stochastic model with a double source of randomness, survival and entry into dependency, and apply it to the three socioeconomic groups obtained with cluster methodology from the 2017 Spanish Household Financial Survey data. We conclude that the effects are very different depending on the group: regarding only the effects of hiring a reverse mortgage on the income of the family, widowed women aged between 81 and 85 years, with low income and expenses as well as little net wealth, and a habitual residence that represents half of her net wealth (Cluster 1) are the most benefited; considering that the highest impact indicators are on the probability of illiquidity and on the value of lack of liquidity, the use of reverse mortgages benefits more the families in Cluster 3 (high income and expenses and really high net wealth, head of household aged between 76 and 80 years) and less the families in Cluster 2 (medium income, net wealth and expenses, head of household aged between 65 and 75 years).

We present a high-resolution spectral study of Fe L-shell extinction by the diffuse interstellar medium (ISM) in the direction of the X-ray binaries Cygnus X-1 and GX 339–4, using the XMM-Newton reflection grating spectrometer. The majority of interstellar Fe is suspected to condense into dust grains in the diffuse ISM, but the compounds formed from this process are unknown. Here, we use the laboratory cross sections from Kortright & Kim (2000) and Lee et al. (2005) to model the absorption and scattering profiles of metallic Fe, and the crystalline compounds fayalite (Fe2SiO4), ferrous sulfate (FeSO4), hematite (α-Fe2O3), and lepidocrocite (γ-FeOOH), which have oxidation states ranging from Fe0 to Fe3+. We find that the observed Fe L-shell features are systematically offset in energy from the laboratory measurements. An examination of over two dozen published measurements of Fe L-shell absorption finds a 1–2 eV scatter in energy positions of the L-shell features. Motivated by this, we fit for the best energy-scale shift simultaneously with the fine structure of the Fe L-shell extinction cross sections. Hematite and lepidocrocite provide the best fits (≈ + 1.1 eV shift), followed by fayalite (≈ + 1.8 eV shift). However, fayalite is disfavored, based on the implied abundances and knowledge of ISM silicates gained by infrared astronomical observations and meteoritic studies. We conclude that iron oxides in the Fe3+ oxidation state are good candidates for Fe-bearing dust. To verify this, new absolute photoabsorption measurements are needed on an energy scale accurate to better than 0.2 eV.

Published: April 2024

We report the detection of extended γ-ray emission from lobes in the radio galaxy NGC 6251 using observation data from the Fermi Large Area Telescope. The maximum likelihood analysis results show that a radio morphology template provides a better fit than a pointlike source description for the observational data at a confidence level of 8.1σ, and the contribution of lobes constitutes more than 50% of the total γ-ray flux. Furthermore, the γ-ray energy spectra show a significant disparity in shape between the core and lobe regions, with a curved log-parabola shape observed in the core region and a power-law form observed in the lobes. Neither the core region nor the northwest (NW) lobe displays significant flux variations in the long-term γ-ray light curves. The broadband spectral energy distributions of the core region and the NW lobe can be explained with a single-zone leptonic model. The γ-rays of the core region are due to the synchrotron-self-Compton process, while the γ-rays from the NW lobe are interpreted as inverse Compton emission of the cosmic microwave background.
Assessment of SDSS-derived Galaxy Morphologies Using HST Imaging
Authors: Osborne Chandler , Salim Samir
Published: April 2024

The Sloan Digital Sky Survey (SDSS) was foundational to the study of galaxy evolution, having revealed the bimodality of galaxies and the relationship between their structure and star-forming activity. However, ground-based optical surveys like SDSS are limited in resolution and depth, which may lead to biases or poor quality in the derived morphological properties, potentially impacting our understanding of how and why galaxies cease their star formation (quench). We use archival Hubble Space Telescope (HST) imaging of ∼2000 SDSS objects to assess the reliability of SDSS-derived morphologies, taking advantage of both SDSS statistical samples and HST’s superior resolution and sensitivity. Single Sérsic fitting and bulge-disk decomposition is performed on HST images for direct comparison with SDSS results. Of the three catalogs of SDSS-derived morphologies considered, none is significantly more accurate or precise than the others. For disk-dominated galaxies (n < 2.5), global Sérsic indices (n) from Meert et al. (hereafter, M15) are preferred. For bulge-dominated galaxies (n > 2.5), Simard et al. (hereafter, S11) and M15 overestimate n by ∼20%, and derived global n from Blanton et al. are preferred. We provide an empirical relation to correct S11 global Sérsic indices. Global R
eff from S11 overestimates R
eff for the largest galaxies by 0.1 dex. Despite these moderate biases, SDSS-derived single-component parameters are generally significantly more robust than SDSS-derived two-component parameters. The bulge Sérsic index (n
bulge) cannot be reliably constrained from SDSS imaging at all, whereas the bulge-to-total (B/T) ratio can be inferred from SDSS (provided that n
bulge = 4 is enforced) but has a large random error of ∼0.2.
Constraining Protoplanetary Disk Winds from Forbidden Line Profiles with Simulation-based Inference
Authors: Nemer Ahmad , Hahn ChangHoon , Li 李 Jiaxuan 嘉轩 , Melchior Peter , Goodman Jeremy
Published: April 2024

Protoplanetary disks (PPDs) are sites of vigorous hydrodynamic processes, such as accretion and outflows, and ultimately establish the conditions for the formation of planets. The properties of disk outflows are often inferred through the analysis of forbidden emission lines. These lines contain multiple overlapping components, tracing different emission regions with different processes that excite them: a high-velocity component (tracing a jet), a broad low-velocity component (LVC; tracing inner disk wind), and a narrow LVC (tracing the outer disk wind). They are also heavily contaminated by background spectral features. All of these challenges call into question the traditional approach of fitting Gaussian components to the line profiles and cloud the physical interpretation of those components. We introduce a novel statistical technique to analyze emission lines in PPDs. Simulation-based inference is a computationally efficient machine-learning technique that produces posterior distributions of the parameters (e.g., magnetic field, radiation sources, and geometry) of a representative wind model when given a spectrum without any prior assumption about line shapes (e.g., symmetry). In this pathfinder study, we demonstrate that this technique indeed accurately recovers the parameters from simulated spectra without noise and background. Future work will provide an analysis of the observed spectra.
Merger-tree-based Galaxy Matching: A Comparative Study across Different Resolutions

Published: April 2024

We introduce a novel halo/galaxy matching technique between two cosmological simulations with different resolutions, which utilizes the positions and masses of halos along their subhalo merger tree. With this tool, we conduct a study of resolution biases through the galaxy-by-galaxy inspection of a pair of simulations that have the same simulation configuration but different mass resolutions, utilizing a suite of IllustrisTNG simulations to assess the impact on galaxy properties. We find that, with the subgrid physics model calibrated for TNG100-1, subhalos in TNG100-1 (high resolution) have ≲0.5 dex higher stellar masses than their counterparts in the TNG100-2 (low resolution). It is also discovered that the subhalos with M
gas ∼ 108.5
M
⊙ in TNG100-1 have ∼0.5 dex higher gas mass than those in TNG100-2. The mass profiles of the subhalos reveal that the dark matter masses of subhalos in TNG100-2 converge well with those from TNG100-1, except within 4 kpc of the resolution limit. The differences in stellar mass and hot gas mass are most pronounced in the central region. We exploit machine learning to build a correction mapping for the physical quantities of subhalos from low- to high-resolution simulations (TNG300-1 and TNG100-1), which enables us to find an efficient way to compile a high-resolution galaxy catalog even from a low-resolution simulation. Our tools can easily be applied to other large cosmological simulations, testing and mitigating the resolution biases of their numerical codes and subgrid physics models.

Published: April 2024

We investigate the application of supervised machine learning models to directly infer the spectral types of ultracool dwarfs (dwarf spectral types ≥M6) using binned fluxes as feature labels. We compare the ability of two machine learning frameworks, k-Nearest Neighbor (kNN) and Random Forest (RF), to classify low-resolution near-infrared spectra of M6 to T9 dwarfs (3100 K ≳ T
eff ≳ 500 K). We used a synthetic training data set of 2400 spectra generated from 24 spectral type standards and validated our models on 315 spectra with previous literature classifications. Classification accuracies within ± 1 subtype were 98.4% ± 0.7% for the kNN model and 95.6% ± 1.2% for the RF model, indicating the kNN performs marginally better for spectral-type estimation. Future studies will explore a broader range of stellar properties such as metallicity, gravity, and cloud characteristics and additional machine learning models.
Divergence of the freshwater sleeper, Neodontobutis hainanensis (Chen, 1985) (Teleostei, Odontobutidae), in the Pearl River basin and on Hainan Island of southern China
Authors: Zhou Mingwei , Xia Jianhong , Li Chenhong
Published: April 2024

Study of divergence of freshwater fish populations between island and adjacent mainland areas can shed light on the phylogeographical relationships of these regions. Neodontobutis hainanensis is a freshwater fish species restricted to Hainan Island and in Guangdong and Guangxi provinces in the southern mainland China. We examine the phylogenetic relationship and population structure of N. hainanensis based on 3,176 nuclear loci using a gene-capture method. STRUCTURE analysis and principal coordinate analyses (PCA) indicate that populations from Guangdong, Guangxi and Hainan are each distinct, except that some individuals of the Guangdong population share minor genetic components with individuals of the Guangxi population. In the concatenated gene tree, the Hainan population is grouped with the Guangdong population, but the coalescent tree groups the Hainan population as the sister to the Guangxi population. Finally, coalescent simulations confirmed the divergence pattern supported by the coalescent tree and revealed a one-way introgression from the Guangxi population to the Guangdong population, which can explain the discordant results supported by the concatenated and coalescent phylogenetic analyses. Due to recent decline of N. hainanensis populations and the genetic patterns in this species, as revealed in this study, the populations in the three areas should be treated as separate conservation units.
Algérie : un silence en héritage, une enfance confisquée

Published: April 2024

Suite à la « décennie noire » (1991 – 2002), la mémoire d’un « passé qui ne passe pas » subsiste encore. L’impossibilité à situer toutes les responsabilités et l’absence d’un processus de symbolisation à effet subjectivant et réparateur chargent de honte, d’effroi et de vide la mémoire collective. En nous appuyant sur deux illustrations cliniques, nous montrons que, s’il est passé sous silence, le vécu traumatique des parents traverse les générations et peut se rejouer chez leurs enfants en produisant des troubles du développement psychique caractéristiques. Ceux-ci peuvent être envisagés comme des manifestations d’apories de la transmission transgénérationnelle. Paradoxalement, grâce au clivage et au désordre, ils peuvent aussi apparaître comme une façon de lutter contre cet héritage qui se prolonge dans la psyché. Un travail d’historicisation est donc nécessaire dans la prise en charge des dyades parents-enfants afin que les trajectoires familiales et l’origine des symptômes soient mises en sens.
Psychologie raciale et médecine : la construction d’une « mentalité africaine » dans le contexte colonial français (XIX e -XX e siècles)
Authors: Peiretti-Courtis Delphine
Published: April 2024

Cet article met en lumière le développement des études médicales sur les caractères « moraux » des peuples et plus spécifiquement des Africain.es et la constitution d’un imaginaire puissant sur l’existence d’une supposé « mentalité africaine », au cours du XIX e siècle et de la première moitié du XX e siècle. Les méthodes de la médecine clinique et de l’anthropologie raciale se voient appliquées à la psychologie des peuples dans un but scientifique mais également économique et politique dans le contexte colonial. L’un des objectifs de l’article est d’éclairer les permanences de ces représentations tout au long de la période, mais également les ruptures et évolutions diverses, liées à l’apport de nouvelles sciences. À partir des premières décennies du XX e siècle, la psychologie des individus n’est en effet plus uniquement déterminée par l’idée de race, mais par d’autres facteurs, externes, comme le milieu, l’alimentation ou la culture. Si l’essentialisation n’est plus biologique, elle est désormais culturelle.
L’habitée : étude du phénomène de dissociation mobilisé au sein d’une relation thérapeutique
Authors: Texier-Bazin Melinda , Poupart Florent
Published: April 2024

L’étude du suivi thérapeutique d’une jeune femme se présentant comme ayant de multiples personnalités permet de discuter ici des enjeux théoriques et cliniques du mécanisme de dissociation. Selon la perspective psychanalytique, la dissociation a une valeur défensive et protège le sujet contre des parties non symbolisées. La recherche contemporaine conceptualise d’autres registres du transfert que ceux relevant du refoulement. La clinique du vécu dissociatif nous amène à considérer un transfert qui relève davantage du clivage, qui se révèle par une utilisation de l’objet, plutôt que d’une relation d’objet. Ces repérages des modalités transférentielles permettent de situer autrement la question diagnostique, en éclairant les processus psychiques mobilisés au cours de la thérapie.
E-Collaboration and Academic Performance of Lecturers
Authors: Al-khateeb Bilal Ahmad Ali
Published: April 2024

Electronic collaboration is increasingly becoming more popular among both the practitioners and the academics; however, the practitioners have taken more advantage of it than the academics. Despite the importance of e-collaboration to the education sector over the years, there appears to have been a dearth in literature. Academic literature is yet to be explored more deeply. Only a few studies on e-collaboration are still considered a crucial feature in collaboration research in the academic domain. The correlation analysis result revealed that e-collaboration has positive strongly correlation with both teaching and research performance at p>0.01. Also, the hypothesis testing result revealed that there is a significant relationship between e-collaboration and teaching performance, and between e-collaboration and research performance at p<0.05 respectively. Based on this, the study therefore concluded that e-collaboration has a positive significant relationship with both teaching and research performance. The study offered limitations and suggestions for future studies.

This article examined the management of electronic health records in virtual health environments using rocket health as a case study. The specific objectives of the study were to determine the healthcare services provided at rocket health; examine the electronic health records management practices adhered to at rocket health; and determine the inhibitors to effective electronic health records management at rocket health. A case study with a mixed-methods research approach was used. Data was collected using questionnaires, document reviews and structured interviews. The study finds that rocket health provided a range of healthcare services encompassing telehealth, pharmacy, last mile delivery, and an online store. These services predominantly operated in a digital format, resulting in the generation of electronic health records (EHRs), and therefore to capture and maintain these EHRs from multiple service points, rocket health implemented a cloud-based system.

Published: April 2024

Students from economically disadvantaged nations (EDN) face significant challenges in accessing high-quality education and securing global internships due to inadequate resources, funding, and infrastructure. The COVID-19 pandemic has highlighted the potential of online platforms for providing accessible, remote education and internship opportunities, aligning with UNESCO's sustainability education objectives. Using the SWOT analysis tool within the context of the experiential learning-driven integrated reflective cycle model (IRC), the research compares onsite and online internship types in higher education to identify areas where interventions can be applied to enhance the online internship experience. The study analyzed 42 interns, both on-site (OSIs) and online (ONIs), to evaluate the constructs of 'experience,' 'action,' 'preparation,' and 'theory”. The findings suggest that OSIs have weaknesses such as poor goal planning, a lack of awareness of relevance, and low communication confidence, while ONIs include a lack of exposure to teamwork and in-person experiences.

Enterovirus 71 Activates Plasmacytoid Dendritic Cell–Dependent PSGL-1 Binding Independent of Productive Infection
Authors: Zhang Xuyuan , Yin Zhao , Zhang Jialong , Guo Hao , Li Jingyun , Nie Xiaohua , Wang Shouli , Zhang Liguo
Published: April 2024

Enterovirus 71 (EV71) is a significant causative agent of hand, foot, and mouth disease, with potential serious neurologic complications or fatal outcomes. The lack of effective treatments for EV71 infection is attributed to its elusive pathogenicity. Our study reveals that human plasmacytoid dendritic cells (pDCs), the main type I IFN–producing cells, selectively express scavenger receptor class B, member 2 (SCARB2) and P-selectin glycoprotein ligand 1 (PSGL-1), crucial cellular receptors for EV71. Some strains of EV71 can replicate within pDCs and stimulate IFN-α production. The activation of pDCs by EV71 is hindered by Abs to PSGL-1 and soluble PSGL-1, whereas Abs to SCARB2 and soluble SCARB2 have a less pronounced effect. Our data suggest that only strains binding to PSGL-1, more commonly found in severe cases, can replicate in pDCs and induce IFN-α secretion, highlighting the importance of PSGL-1 in these processes. Furthermore, IFN-α secretion by pDCs can be triggered by EV71 or UV-inactivated EV71 virions, indicating that productive infection is not necessary for pDC activation. These findings provide new insights into the interaction between EV71 and pDCs, suggesting that pDC activation could potentially mitigate the severity of EV71-related diseases.

Thanks to a long-term monitoring program, we found for the first time in Italy a migrating specimen of Condica capensis (Lepidoptera: Noctuidae). This finding is likely linked to the strong winds blowing from North Africa just before the collection of the specimen. Condica capensis is considered to be a migrant to the European continent except for Spain, where it is resident. It is found across Africa, the Indian subcontinent, South-East Asia, and Australia.

Context

Baseball pitching requires fast and coordinated motions of the whole body to reach high ball speeds, putting considerable strain on the musculoskeletal system, particularly the shoulder and elbow.

Objective

To describe musculoskeletal symptoms and the functional status of the shoulder and elbow in male high school baseball pitchers.

Design

Descriptive epidemiology study.

Setting

Dutch baseball talent academies.

Patients or Other Participants

One hundred twenty-five male high school baseball pitchers aged 12 to 18 years who participated in 1 of the 6 Dutch baseball talent academies and the Dutch National U-18 team were recruited and enrolled.

Main Outcome Measure(s)

Musculoskeletal symptoms, functional status of the shoulder and elbow were registered for each player every 6 months over 2 consecutive baseball seasons through self-assessment questionnaires, including the Kerlan-Jobe Orthopaedic Clinic (KJOC) and the Western Ontario Shoulder Instability Index (WOSI) questionnaires.

Results

Five hundred seventy musculoskeletal (MSS) symptoms in 93 of the 125 players were reported. The average 6-month prevalence for symptoms of the throwing shoulder was 37% (95% CI = 33%–41%), and for the elbow 37% (95% CI = 31%–42%), followed by the lower back with 36% (95% CI = 26%–45%). The baseball pitchers who experienced only shoulder symptoms had an average KJOC score of 80.0 (95% CI = 75.3–84.7) points, whereas those with only elbow symptoms reported a score of 90.2 (95% CI = 89.2–95.3). On the WOSI questionnaire, baseball pitchers scored an average of 421.2 (95% CI = 200.1–642.4) points.

Conclusions

In a cohort of Dutch high school baseball pitchers, one-third reported shoulder and elbow symptoms on the throwing side, with reduced functional status and lower back symptoms. Future efforts should focus on developing preventive strategies through early symptom detection, aiming to prevent symptom progression and, ultimately, the development of severe injuries.
Athletic Trainers’ Perceptions of Implementing Psychological Strategies for Patient Management: A Systematic Review
Authors: Brinkman Caitlin , Reiche Elaine , Baez Shelby
Published: April 2024

Objective

To synthesize the best available evidence regarding the perceptions and current clinical practices of athletic trainers (ATs) in integrating psychological skills into patient management.

Data Sources

PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL; via EBSCOhost), PsycInfo (via EBSCOhost), SPORTDiscus (via EBSCOhost), and Scopus (via Elsevier).

Study Selection

Studies had to investigate the current clinical practices and perceptions of certified ATs in integrating psychologically informed practice for patient management. Studies that had level 4 evidence or higher were included. Studies were excluded if they were published before 1999, the primary language was not English, they involved athletic training students or other rehabilitation specialists, or they explored the athlete’s and/or patient’s perception of psychosocial techniques or strategies.

Data Extraction

This systematic review is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 Statement in Exercise, Rehabilitation, Sport Medicine and Sports Science guidance.

Data Synthesis

A total of 1857 articles were reviewed, and 8 met inclusion criteria. Two studies had level 2a evidence, 4 studies had level 4a evidence, and 2 studies had level 4b evidence. Six studies were rated as good quality, and 2 studies were rated as lesser quality. The included studies demonstrated a high-quality body of evidence with consistent results, which strengthens the review findings.

Conclusions

Athletic trainers have the knowledge to identify when athletes are psychologically affected by injury and can identify common psychological responses. Although ATs acknowledge the value of implementing psychosocial strategies, a lack of confidence in implementing basic or advanced techniques, feeling underprepared by their educational program, and a lack of clinical training appear to affect the use of psychosocial techniques in clinical practice and the rate of mental health recognition and referral among ATs.

Introduction/Purpose:

The Acute Cystitis Symptom Score (ACSS) was developed as a simple and self-reporting questionnaire for diagnosing and monitoring acute uncomplicated cystitis in female patients. It consists of 18 questions placed in four subcategories: (1) typical symptoms, (2) differential diagnosis, (3) quality of life and (4) coexisting gynecological conditions. It has been translated into many languages. The purpose of this work is the linguistic evaluation of ACSS in the Greek language.

Materials and Methods:

The translation of ACSS into Greek was carried out in accordance with international standards and guidelines. The process consisted of 4 stages: in the 1st and 2nd stage a translation was made into the target language (Greek) from the original (Russian, English) by native speakers, while reverse translation and re-evaluation was made by experts whose mother tongue language is the target language. In stage 3, a cognitive assessment was performed by female subjects with and without a history of uncomplicated urinary tract infection. At this stage, based on the degree of understanding, the final draft was chosen between the two drafts of different origins (Russian or English). In stage 4: the final clinical evaluation was performed by female subjects with acute episode of uncomplicated cystitis (Arm 1 - Patients) and female subjects undergoing treatment for any other diseases (Arm 2 - Control). The Memorandum of Understanding between the Greek Study Group of ACSS and the copyright holders of ACSS was made on 17 November 2019 while it has been approved by the Ethics Committee of the Hospital. The diagnosis of acute uncomplicated cystitis was made based on the history and results of laboratory findings.

Results:

The two pre-final versions in Greek were randomly applied to 15 healthy women aged between 89 and 22 years. The mean age of the final sample was 23.84 years. The level of education differed between a doctorate and a primary school diploma with most participants graduating from universities (8/30) and high school (8/30). According to the answers, 20 women would prefer the English standard translation, compared to 10 women, who preferred the Russian translation. The 2: 1 ratio was similar whether the participants had higher education or not. No significant difference was observed in the mean age of the participants who chose one or the other version.

Conclusion:

The process of translating and adapting a study instrument such as a questionnaire for a different ethnic group is a difficult task since it requires to adapt it in a culturally relevant and comprehensible form despite peculiarities of the target language. Considering these difficulties, we were able to develop a linguistically validated Greek version of the ACSS, which now can be used for clinical and research purposes in a multidisciplinary fashion.

Background:

Tissue-engineered periodontal ligament (PDL) around a dental implant by using PDL stem cells (PDLSCs) may be useful in periodontal regeneration and can reduce or eliminate certain shortcomings of dental implants.

Materials and Methods

PDLSCs were isolated from extracted human PDL cells and cultured in a bioreactor. They were identified using markers CD45, CD73, CD90, CD105, and CD146. After the formation of multiple cellular layers, they were then attached on titanium mini dental implants and placed in rabbit tibia. The rabbits were sacrificed after 9 months, and the implants were analyzed histologically and radiographically by Cone beam computed tomography (CBCT).

Results:

Isolated PDLSCs obtained from human premolars showed a colony-forming ability on the 7th day and 14th day. Immunocytochemistry revealed that cells had taken up the adequate positive stains for primary antibodies CD73, CD90, CD105, and CD146 and negative staining for CD45. The histological sections obtained from sacrificed rabbits, when viewed under the light microscope, clearly showed the presence of PDL around dental implants. CBCT examination showed that the implant was well within the bone and did not migrate. The site appeared to be normal without any lytic changes in the bone.

Conclusion:

It can safely be postulated from the present study that tissue engineering of PDL can be achieved around dental implants using PDLSCs. Important inter-tissue interactions like the formation of a functional PDL around the implantation site, and induction of bone formation in the vicinity of the implants may be possible. Future research in humans is required for further research.
