Authors: Sun Fan , Zhu Jing , Zhang Jin , Xie Tian , Guo Feng-Mei
Published: December 2022

Objectives. The purpose of this study was to explore the effects of age and gender on left atrial-ventricular volumetric indices in healthy adults by left atrial-ventricular volume loops (LA-LV V-LOOPs) and provide novel insight into diagnosis and treatment of LA-LV abnormality.
Methods. 57 healthy adults were involved. Transthoracic echocardiography was utilized to obtain conventional left heart function parameters and three-dimensional echocardiography(3DE) images. Then, dynamic heart model (DHM) was used to analyze 3DE images to obtain left atrial-ventricular volumes. Left atrial-ventricular volume loops were established according to left atrial-ventricular volumes after analysis. Morphological characteristics of LA-LV V-LOOPs and volumes of left atrial-ventricular were compared among healthy adults of different age as well as different genders to assess left heart function.
Results. LA-LV V-LOOPs showed an upward shift between the youth group and the middle-age group, as well as between the middle-age group and the old group in the coordinate axis. Left ventricular volume indexes of male group were higher than that of female group at 25% (56.89(IQR66.14-47.43) VS 48.30(IQR57.98-43.14), P=0.051), 50% (42.10(IQR48.56-32.45) VS 33.10(IQR41.50-30.37), P=0.037), 75% (28.18(IQR36.94-24.94) VS 23.89(31.66-21.17), P=0.042) of left ventricular systole.
Conclusion. LA-LV V-LOOPs could intuitively reflect the variety of left atrial-ventricular function by different positions of LA-LV V-LOOPs on the coordinate axis among adults of different ages and sexes.

Published: December 2022

Pain perception can be studied as an inferential process in which prior information influences the perception of nociceptive input. To date, there are no suitable psychophysical paradigms to measure this at an individual level. We developed a quantitative sensory testing paradigm allowing for quantification of the influence of prior expectations versus current nociceptive input during perception. Using a Pavlovian-learning task, we investigated the influence of prior expectations on the belief about the varying strength of association between a painful electrical cutaneous stimulus and a visual cue in healthy subjects (N = 70). The belief in cue-pain associations was examined with computational modelling using a Hierarchical Gaussian Filter (HGF). Prior weighting estimates in the HGF model were compared with the established measures of conditioned pain modulation (CPM) and temporal summation of pain (TSP) assessed by cuff algometry. Subsequent HGF-modelling and estimation of the influence of prior beliefs on perception showed that 70% of subjects had a higher reliance on nociceptive input during perception of acute pain stimuli, whereas 30% showed a stronger weighting of prior expectations over sensory evidence. There was no association between prior weighting estimates and CPM or TSP. The data demonstrates relevant individual differences in prior weighting and suggests an importance of top-down cognitive processes on pain perception. Our new psychophysical testing paradigm provides a method to identify individuals with traits suggesting greater reliance on prior expectations in pain perception, which may be a risk factor for developing chronic pain and may be differentially responsive to learning-based interventions.

Published: December 2022

Background: The purpose of this study was to evaluate secondary traumatic stress disorder among healthcare professionals (HCPs), particularly physiotherapists working in critical care, neurology, cardiology, pulmonology, and mental health departments in Saudi Arabia. This study highlights the prevalence of burnout and the level of stress endured by HCPs and identifies available preventive mechanisms to alleviate their emotional strain.
Methods: A cross-sectional study was conducted from July 2021 to July 2022 in which healthcare workers, including physiotherapists from the critical care, emergency, neurology, cardiology, pulmonology, and mental health departments, were evaluated. The study collected data to measure secondary traumatic stress disorder among the participants. The Secondary Traumatic Stress Scale (STSS) was administered and analyzed using statistical tests. The prevalence of burnout, induced stress, and secondary traumatic stress were assessed.
Results: A total of 78 healthcare workers were evaluated, of which 25.6% worked in the neurosurgery department and 11.5% work in the critical care and emergency departments. Among the participants, 28.2% worked more than 45 hours per week and 21.8% slept less than 5 hours per day. Of the healthcare workers, 12.8% suffered from severe stress, 52.6% suffered from moderate stress, and 28.2% suffered from mild stress. The three factors of the STSS were measured among the study subjects – the intrusion score (mean = 10.47), avoidance score (mean = 16.18), and arousal score (mean = 11.06) and their means were calculated accordingly.
Conclusion: The study shows the need to implement a wide range of interventional programs to improve communication skills, reduce emotional distress, and implement relaxation activities in healthcare environments.

The effect of the COVID-19 epidemic on Moroccan sectoral indices: The entropy approach
Authors: Bouhlal Fadwa , Brahim Sedra Moulay
Published: December 2022

The current study investigates the impact of the Coronavirus 2019 (COVID-19) pandemic on the volatility of Moroccan stock market sectoral indices. Shannon entropy with multiple estimators and Rényi entropy for different scales were calculated from February 1, 2019 to May 1, 2022, to measure volatility in the Banking, Oil and Gas, Construction and Building Materials, Beverage, Food Producers and Processors, Distributors, and Mining sector’s indices. In this regard, this study uses three periods to quantify the uncertainty in Moroccan sectoral indices before, during, and after the first year of the COVID-19 pandemic in Morocco. The empirical results from Shannon and Rényi entropies indicated higher volatility during the COVID-19 pandemic for all sectoral indices except Oil and Gas. However, the consumer staples sectors have shown a form of resilience compared to other sectors. Indeed, the impact of COVID-19 on the consumer staples sectoral indices’ volatilities was negligible compared to other sectors. In addition, investing in a portfolio composed of Mining or Construction and Building Materials stocks was risky due to the increased volatility before and during the epidemic. However, after the COVID-19 pandemic, the entropy level corresponding to all sectors has rearranged except the Beverage sector, which kept the lowest entropy during the three periods. Thus, it seems that the Beverage sector was a safe investment for the three periods. The findings are crucial for governments, businesses, private and public authorities, and investors to create recovery action plans for sensitive sectors and give investors trust to make smarter investment decisions.

Published: December 2022

Objective:

We designed this systematic review and meta-analysis to estimate the pooled efficacy
and safety profile of different types of stem cells in treating patients with cerebral palsy (CP).

Methods:

We systematically searched PubMed, Scopus, EMBASE, Web of Science, Google Scholar, and
also gray literature, including references of the included studies which were published before November
2021. We extracted data regarding the total number of participants, first author, publication year, country
of origin, mean age, cell type, cell dose, cell source, method of transplantation, duration of follow-up,
Gross motor function, Ashworth scale, and adverse events.

Results:

We found 2073 articles by literature search; after deleting duplicates, 1194 remained. Nine articles
remained for meta-analysis. The SMD of GMF-66 score (after-before) treatment was 1.5 (95%
CI:0.7-2.3) (I2 = 89.9%, P < 0.001). The pooled incidence of Gastrointestinal (GI) complications after
transplantation was 21% (95% CI:9-33%) (I2 = 56%, P = 0.08). The pooled incidence of fever after transplantation
was 18 % (95% CI:6-30%) (I2 = 87.9%, P = 0.08 < 0.001)

Conclusion:

The result of this systematic review and meta-analysis show that stem cell therapy in cerebral
palsy has neuroprotective properties from anti-inflammatory and anti-apoptotic activities. Stem cell
therapy seems to be a promising adjunct to traditional therapies for cerebral palsy patients.
Numerical Modelling of the Compressive and Tensile Behavior of Ultra-High Performance Concrete in Beams
Authors: Jabbar Adil M. , Abdul-Husain Zinah A. , Danha Lubna S.
Published: December 2022

INTRODUCTION

Ultra-high performance concrete (UHPC) differs in its structural behavior from conventional concrete upon loading due to its high compressive and tensile strength, stiffness, toughness, and durability. Therefore, UHPC needs an appropriate constitutive model to simulate its mechanical properties in finite element analysis (FEA).

METHOD

In this study, numerical models were developed to trace the structural behavior of UHPC beams upon loading since beam behavior depends on the constituents' response to compression and tension. New numerical models were formulated to display the stress-strain relationships of UHPC in compression and tension by adopting a new methodology that depended on actual results. The compressive stress-strain relationship consisted of two portions; the ascending one for elastic and strain hardening up to compressive strength and a descending curve for the strain-softening until reaching a strain of 0.0062.

RESULT

A linear tensile stress-strain relation was applied for the elastic tensile behavior up to tensile strength. Then, a tri-linear relationship was applied for the stiffness degradation and crack propagation upon debonding fibers from the concrete matrix until fracture. These numerical models were used in Abaqus software to simulate the UHPC beam behavior.

CONCLUSION

The developed models were verified and approved for beams' behavior upon loading in flexure and shear. The results indicated that the models could predict the UHPC beams' response throughout the entire loading range from the beginning until failure. The verification included bear capacity, deflection, crack pattern, and stress distribution.

Published: December 2022

Viral diseases are one of the major causes of mortality worldwide. The emergence of
pandemics because of the COVID virus creates a dire need for an efficient mechanism to combat
the disease. Viruses differ from other pathogenic infections; they render the host immune system
vulnerable. One of the major challenges for developing antivirals is the resistance developed by the
overuse of drugs, which is inevitable as most viral diseases require a large number of doses. Viral
infection detection, prevention, and treatment have significantly benefitted from developing several
innovative technologies in recent years. Nanotechnology has emerged as one of the most promising
technologies because of its capacity to deal with viral infections efficiently and eradicate the
lagging of conventional antiviral drugs. This review briefly presents an overview of the application
of nanotechnology for viral therapy.

Published: December 2022

Background:

The era of flexible antennas started long ago because they are cost-effective
while offering several advantages, such as good flexibility, stretchability, and compactness. Although
several synthetic and natural polymers with good flexibility are available, the first flexible antenna is
designed with polyimide materials (polymers), often known as engineering plastics.

Objective:

To fabricate a compact antenna with a higher gain than other existing ones and the bending
loss of the proposed antenna is lower than other existing ones, this study proposes an ideal antenna.

Methods:

A polyimide (PI)-based flexible antenna with a defected ground structure is proposed for
telemedicine and wireless applications, and we implement this antenna using microstrip feeding.
The proposed antenna consists of a polyimide substrate with a thickness of 0.1 mm, a relative permittivity
of 3.15, a loss factor of 0.0013, and a compact overall size of 25 x 32 x 0.1 mm3.

Results:

The proposed antenna operates on three frequencies, including 2.4 GHz (ISM or telemedicine
application), 5.5 GHz (WiMAX band), and 7.5 GHz (wireless radio band). The proposed antenna
produces impedance bandwidths of 10.16%, 14.54%, and 5.33% at frequencies of 2.4 GHz,
5.5 GHz, and 7.5 GHz, with gains of 4.9 dB, 5.1 dB, and 5 dB.

Conclusion:

The proposed antenna is simulated using Ansys High-Frequency Structure Simulator
(HFSS) software. A good agreement is found between the measured and simulated results.
An Image Recognition Method Based on Dynamic System Synchronization
Authors: Yu Wanbo , Chen Xiaoran , Li Xiang
Published: December 2022

At present, image recognition technology first classifies images and outputs category
information through the neural network. The next step involves the search. Before retrieval, the
feature database needs to be established, followed by one-to-one correspondence. This method is
tedious, time-consuming and has low accuracy. In computer vision research, researchers have
proposed various image recognition methods to be applied in various fields and made many
research achievements. However, at present, the accuracy, stability and time efficiency cannot
meet the needs of practical work. In terms of UAV image recognition, high accuracy and low
consumption are required. Previous methods require huge databases, which increases the
consumption of UAVs. Taking aerial transmission and line images as the research object, this
paper proposes a method of image recognition based on chaotic synchronization. Firstly, the
image is used as a function to construct a dynamic system, and the function structure and
parameters are adjusted to realize chaos synchronization. In this process, different types of
images are identified. At the same time, we research this dynamic system characteristics and
realize the mechanism of image recognition. Compared with other methods, the self-built aerial
image data set for bird's nest identification, iron frame identification and insulator identification
has the characteristics of a high identification rate and less calculation time. It is preliminarily
proven that the method of synchronous image recognition is practical, and also worthy of further
research, verification and analysis.
Utilization of Durian Durio Zibethinus seed flour and Kelakai Stenochlaena palustris leaf flour formulation as feed for Nile Tilapia Oreochromis niloticus
Authors: Bakrie Restu , Sulistiyarto Bambang
Published: December 2022

Small-scale fish farmers have financial limitations to buy expensive commercial pellets to meet fish feed needs. Therefore, it is necessary to find alternative feeds that are cheap and able to support fish growth. Durian seeds (Durio Zibethinus) and Kelakai leaves (Stenochlaena palustris) are potential plant materials for additional fish feed which are abundant in Central Kalimantan Province. This study aims to determine whether additional feed formulations made from durian seed meal andelakai leaf meal can provide significant growth in tilapia (Oreochromis niloticus) rearing. The study used an experimental approach with a completely randomized design (CRD) with 3 treatments and 3 replications. The feed formulation is a mixture of pellets with 95% durian seed meal and 5% melakai leaf meal. Additional feeding is based on the following treatment: Treatment A, given commercial feed made by the factory brand MS prima Feed 1000 as much as 5% of the total weight of the fish kept, Treatment B: given formulated feed (90% pellets + 10% durian seed flour and kelakai leaf flour) as much as 5% of the total weight per day, Treatment C: given formulated feed (95% pellets + 5% mixture of durian seed flour and kelakai leaf flour) as much as 5% of the total fish weight per day. The results showed that the feeding of pellet formulations with durian seed flour and kelakai leaf flour as much as 10 % of body weight per day resulted in the highest growth in length and weight of fish.  Thus durian seed flour and Kelakai leaf flour can be used as additional feed for Nile tilapia to help increase fish growth and reduce fish feed costs.

Authors: Kovács Szabolcs
Published: December 2022

A növekvő és folyton változó nemzetközi verseny, a növekvő piaci volatilitás és a mindinkább egyedi termékek iránti kereslet (személyre szabott gyártás), valamint a termékek rövidebb életciklusa komoly kihívások elé állítják a vállalatokat, aminek a hagyományos termelési rendszerek már nem képesek megfelelni. Az ipar 4.0 egy új gyártási paradigma, mely nagy hangsúlyt fektet az intelligens termékek és folyamatok létrehozására. Az egyedi gyártás minél hatékonyabb megvalósítása került előtérbe, tömegtermelésnek megfelelő kondíciók mellett. A készletre történő termelést felváltja a vevői rendelésre történő gyártás. Az ipar 4.0 téma iránti növekvő érdeklődés ellenére azonban ez még mindig nem konszenzusos koncepció. Nincs egyértelmű elképzelés erről az új gyártási paradigmáról, ezért a szakirodalom bemutatásán keresztül próbálom meg ismertetni a fellelhető ipar 4.0 definíciókat, deklarálni a koncepció technikai elemeit és részletesen bemutatni azokat, ezáltal is mind tisztább képet alkotni a koncepcióról.

Published: December 2022

A large portion of rural human residents in Mexico are established in the states with greater biological diversity, and continue using a variety of wildlife species as sources of protein, fat, medicinal substances, clothes, adornments, ritual objects, and income, among other purposes. Our aims in this study were: 1) identify the main wildlife species that are part of local knowledge and are used, 2) describe the hunting techniques used by inhabitants of rural communities, and 3) identify the main wildlife species considered harmful between two groups of inhabitants of rural communities settled around the Communal Natural Protected Area El Gavilán on the central coast of Oaxaca, in southwest Mexico. We conducted fieldwork during four visits to the communities between June and December 2015. We obtained information through open conversations with structured and in-depth interviews. We calculated the Importance Culture Index (ICI) and the Importance Damage Index (IDI) per wildlife species. We recorded 51 wild species, which are part of the knowledge of the studied communities, and seven different uses were identified. There was no significant difference in the knowledge of wildlife among the study groups, but there was a significant difference in the use of wildlife. In general, the inhabitants of the communities around the NPA El Gavilán have extensive knowledge and make use of its wildlife, but there are differences in the uses of these species. Here we present a synthesis of the most relevant knowledge and uses of wildlife in communities around a natural protected area.

El monitoreo de las moscas de la fruta utilizando atrayentes efectivos es una herramienta determinante para integrar las estrategias de control. En este estudio se comparó la efectividad de captura de Anastrepha obliqua con seis atrayentes alimenticios disponibles comercialmente en México. En tres experimentos en huertas de mango variedad manila, CeraTrap®, un atrayente de hidrólisis enzimática de proteínas de origen animal, resultó ser significativamente más efectivo que otras proteínas de hidrólisis ácida con bórax como Captor 300®, Winner 360® y Flyral®, así como un nuevo atrayente, Agrotrap® desarrollado a partir de la mezcla de proteína hidrolizada, levadura, acetato de amonio y vinagres. Las capturas de A. obliqua con CeraTrap resultaron estadísticamente similares que una mezcla de Captor 300 + bórax y Orga Fly Trap®, un adyuvante suministrado para potenciar la actividad de proteínas convencionales. La cuantificación del pH y la emisión de amoniaco por los atrayentes comerciales evaluados no mostraron una relación clara con los niveles de atracción en campo. CeraTrap es estable durante varias semanas y continúa siendo la opción más efectiva para el monitoreo de poblaciones de A. obliqua en mango.

The implementation of the physical distancing policy as an effort to prevent the transmission of the COVID-19 virus seems to have resulted in loneliness problems for students. Many studies have shown that loneliness is bad for health, such as decreased immunity and cognitive function. By knowing groups vulnerable to loneliness, appropriate preventive and curative measures can be taken. Unfortunately, few studies discuss the differences in the level of loneliness in groups of men and women. This study aims to determine whether there are differences in the level of loneliness in male and female university students during the COVID-19 pandemic. The approach used is quantitative with a comparative design. The total subjects were 192 University students consisting of 148 women (77%) and 44 men (23%). The participants were obtained using an online questionnaire through the accidental purposive sampling method. The research instrument used is the UCLA Loneliness Scale Version 3 Indonesian edition which has an alpha coefficient of 0.92. Data analysis used a different independent sample t-test. The data obtained shows that the average loneliness for men is 38,272 and for women 38,108. Based on the difference test, we obtained the following result t (190) = 0.127,  p 0.05. So it can be concluded that there is no significant difference in loneliness between male and female university students.

Pace of life has been found to be associated with various life outcomes such as mental health and well-being to information distribution and economic development. Every city has a different pace of life due to its specific characteristics. Across two studies, we examined the role of temperature and number of populations (city size) as the predictors of pace of life. In the first study, we compared Bandung and Jakarta and in the second study, we compared Jakarta and Depok. Each pace of life index was generated by mean scores of walking speed, working speed and clock accuracy. Through field observation in each city's Central Business District, we found that based on temperature, Jakarta has higher means of walking speed (M=15.3) compared to Bandung (M=13.6), significantly with mean difference 1.71 (t(158)=5.32, p.001, d=0.841). Jakarta is also significantly higher on the working speed indicator (M=25.7) compared to Bandung (M=17.5) with mean difference 8.22 (t(18)=2.49, p=.011). In the second study, we found that  Jakarta has significantly lower means of walking speed (M=14.3) compared to Depok (M=17.9) with mean difference 3.54, t(158)=11.058, p.001. Similarly, Jakarta also has lower means of working speed (M=18.58) and clock accuracy (M=1.33) compared to Depok (M working speed=19.9, M clock accuracy=3.67), although not significant.  Overall, as predicted, based on temperature, the colder city Bandung has a faster pace of life compared to Jakarta. Jakarta also has a faster pace of life compared to Bandung, although significant only for its walking speed.

The delivery service industry is boosting too much under the influence of e-commerce. So, there is a need to reform the delivery of the postal sector to meet the needs of consumers. Most of the postal offices have been served via government to government (G2G), and in recent years, due to e-commerce and corona disease, they have been developing business to consumer services (B2C), business to business (B2B), and direct to customer (D2C). The study examines how service quality affects customer trust, consumer satisfaction, and customer loyalty in the postal delivery service. It aims to provide information to delivery service companies and foreign investment companies in making strategic decisions. All structures are measured on a seven-point Likert scale. A total of 290 valid responses were used out of 358 distributed surveys, excluding 68 responses with irrelevant and incomplete data. These were analyzed using SPSS 21.0 and AMOS 20.0 statistic package programs. The outcome of the analysis showed that the four components of service quality constructs of delivery service have no significant effect on trust. However, they affect satisfaction, while tangibility and empathy have not shown such trustworthy effects on customer fulfillment.
An Evidence-Based Best Practice Perioperative Matrix Eliminates Allogenic Blood Transfusions in Simultaneous Bilateral Total Knee Replacements (Preprint)
Authors: Symonds Tristan , McEwen Peter , Faruque Ryan
Published: December 2022

BACKGROUND

Simultaneous bilateral total knee replacements (SBTKR) are associated with increased blood loss and a higher transfusion rate. Blood transfusions post total knee replacement increase infection rates, length of stay and costs to the healthcare system.

OBJECTIVE

The purpose of this study was to evaluate the effect of an evidence-based perioperative matrix on allogenic blood transfusions in patients undergoing SBTKR.

METHODS

A retrospective analysis was performed on a consecutive series of patients who underwent SBTKR by a single surgeon utilizing evidence-based preoperative, intraoperative and postoperative strategies to reduce the need for blood transfusions. Patients had serial haemoglobins days one to three post-operatively to identify percentage drop. A transfusion threshold of 70g/l Hb or a symptomatic patient were used. Subgroup analysis of patients on aspirin preoperatively was performed.

RESULTS

There were 168 consecutive patients with a mean age of 65 ± 7 years. No patients required a transfusion following surgery. One patient was readmitted for a transfusion after a gastrointestinal bleed. Percentage blood loss did not correlate with age, BMI or sex. There was a correlation between preoperative haemoglobin and percentage haemoglobin drop day one (P<0.001) and day two (P=0.003). Percentage Hb drop was no greater in patients taking a cardiac dose of aspirin pre-operatively (P=0.48).

CONCLUSIONS

An evidence-based best practice perioperative matrix may eliminate the need for blood transfusion in optimised patients undergoing simultaneous bilateral total knee replacements.

Published: December 2022

Фактори ризику гіпотермії включають умови, за яких знижується термогенез, порушується терморегуляція та зростають втрати тепла. До основних груп факторів ризику гіпотермії відносяться: низька температура зовнішнього середовища; дія холоду, що періодично повторюється; зниження теплопродукції; порушення терморегуляції при тяжких травмах і захворюваннях; підвищення тепловіддачі внаслідок антропологічних особливостей (вік, раса, стать, конституція), патологічних станів (шкірних захворювань, вазодилатації, захитування та інших соматичних та неврологічних захворювань) або умов зовнішнього середовища (високої теплопровідності, вологості повітря, швидкості вітру). Даний літературний перегляд можливих причин загального переохолодження та факторів, що сприяють йому, може стати в нагоді при плануванні співробітниками соціальних та спеціалізованих служб заходів із запобігання ненавмисній гіпотермії у робітників різних галузей господарства, військовослужбовців та соціально незахищених верств населення, а також при ретроспективному аналізі причин холодової травми співробітниками рятівних служб, лікарями першого контакту, комбустіологами та персоналом відділень інтенсивної терапії.

Співробітники кафедри анестезіології, інтенсивної терапії та медицини невідкладних станів ФПО ДДМУ протягом 15 років займаються підготовкою лікарів-інтернів різних спеціальностей до ЛІІ «Крок-3», що являє собою складний динамічний процес, який вимагає ретельного дослідження та корекції. Окремо дистанційна форма навчання може використовуватися як тимчасовий захід за умов неможливості проведення очного навчання з наступним переходом до традиційної форми. Методологія навчання лікарів-інтернів різних спеціальностей за модулем «Невідкладні стани» повинна бути гнучкою залежно від динамічних змін соціально-психологічного статусу молодих колег.
