Published: August 2023

Introduction:

Dy2Sn2O7 nanoparticles (Dy2Sn2O7 NPs) were generated in the attendance of
rheum gum, papaver somniferum gum, ferula assa feotida gum, barberry juice from Dy(NO3)3·5H2O
and SnCl4·5H2O.

Methods:

The study of the structure of the specimens verified the generation of nanocatalysts in the
scope of 20±5 nm. Synthesized catalysts with a variety of natural compounds were investigated by
employing various methods. The characteristics of Dy2Sn2O7 were determined by SEM, TEM, EDX,
and XRD. Due to the persistent colloidal stability, high mechanical, thermal sustainability, and high
ionic internal character, the system can be deemed as an efficient catalyst by deploying the guest-host
approaches.

Results:

Using industrial waste as raw materials and turning it into valuable products is an important
phenomenon in green chemistry. Carbon dioxide is among these substances. This substance is less reactive and it is difficult to use them in a reaction.

Conclusion:

We announce the employment of CO2, isocyanides, and o-halo anilines in a multicomponent reaction for the production of quinazolines in the participation of Dy2Sn2O7 as a nanocatalyst.

Published: August 2023

Background:

With increasing uterine cancer in developing nations, there is a need for timely determination of the diagnosis, prognosis, and management options to reduce morbidity and mortality.

Objective:

To analyze the socio-demographic, etio-pathological features and management of uterine cancer and evaluate its correlation with grading/staging in our population.

Methods:

This retrospective descriptive study analyzed data from 97 histologically proven uterine cancer cases. Age, parity, symptoms, co-morbidities, body mass index (BMI), ultrasound features, histopathology type, stage and grade of the tumor, type of hysterectomy done, complications and mortality were analysed. Statistical analysis was done using ANOVA and chi-square test, and a p-value<0.05 indicated statistical significance.

Results:

The mean age of diagnosis was 57.91 years, and the mean BMI was 29.32 Kg/m2. Majority of the patients were multiparous (42.27%), and only 10% were nulliparous. The disease was detected at an earlier age in nulliparous and obese women. Diabetes and hypertension were found in 75.25%. Most of the patients were detected with stage I cancer (80.6%). Patients diagnosed with uterine cancer on biopsy were treated with total abdominal hysterectomy with bilateral salpingo-oophorectomy andbilateral pelvic lymph node dissection (55.8%). Over 36% of patients received postop radiotherapy and/or chemotherapy. 21% patients were lost to follow-up and 12.37% died. Also, 24 cases had postoperative complications (wound infection).

Conclusion:

Uterine cancer is common among obese women with diabetes and hypertension. In nulliparous and the obese, the cancer was detected at an earlier age. Most of our patients had stage 1 disease, and 90% was endometroid cancer. The study highlights the importance of endometrial sampling before hysterectomy in perimenopausal women to avoid suboptimal surgery in patients diagnosed with uterine cancer after a simple hysterectomy.

Published: August 2023

In this paper, a model for characterizing the dynamics of vector-borne diseases is put out, emphasizing Japanese encephalitis. The susceptible-infectious-recovered (SIR) model for the host population and the susceptible-infectious (SI) model for the vector and reservoir populations are used to examine the role of host-vector-reservoir dynamics and their interplay. The standard incidence rate represents the probability of an actual disease contact. The model has two equilibrium points: an endemic equilibrium point that only exists under specific circumstances and a disease-free equilibrium point that always exists. The stability analysis of the model’s equilibrium point has been established. The basic reproduction number is calculated using the next-generation matrix method. A sensitivity analysis on models supported by numerical simulations is provided to demonstrate the critical parameter that affects the spread of disease. Our findings indicate that vector-reservoir transmission is the primary cause of endemic. Controlling vector-reservoir transmission lowers the likelihood of human infection and creates disease-free settings.

This paper presents the performance of PVD and vacuum consolidation as ground improvement method at the construction of Kayu Agung – Palembang Toll Road. The analysis was based on observation data collected between STA 00+000 and STA 09+000. The PVD was installed to a depth where the conus resistance of 80 kPa was achieved. Thus, the length of PVD varies from 5 to 13 m while the actual depth of clay deposit could reach 20 m. As many as 42 settlement plate data were collected and analyzed using Asaoka method to obtain the predicted final settlement, the coefficient of consolidation and the time to reach 90% degree of consolidation. The results were compared with the duration of vacuum consolidation application and the recorded settlement when the vacuum pressure was stopped i.e., when settlement plate recorded no differential settlement in three readings. The duration of vacuum consolidation application generally longer than the t90 predicted by the method and the actual settlement was larger than the predicted final settlement. This study concluded that the variation of the t90 and the magnitude of settlement at t90 have close relationship with the length of PVD and the condition of the soil layer.

Published: August 2023

Background

Artificial intelligence (AI) is often promoted as a potential solution for many challenges health care systems face worldwide. However, its implementation in clinical practice lags behind its technological development.

Objective

This study aims to gain insights into the current state and prospects of AI technology from the stakeholders most directly involved in its adoption in the health care sector whose perspectives have received limited attention in research to date.

Methods

For this purpose, the perspectives of AI researchers and health care IT professionals in North America and Western Europe were collected and compared for profession-specific and regional differences. In this preregistered, mixed methods, cross-sectional study, 23 experts were interviewed using a semistructured guide. Data from the interviews were analyzed using deductive and inductive qualitative methods for the thematic analysis along with topic modeling to identify latent topics.

Results

Through our thematic analysis, four major categories emerged: (1) the current state of AI systems in health care, (2) the criteria and requirements for implementing AI systems in health care, (3) the challenges in implementing AI systems in health care, and (4) the prospects of the technology. Experts discussed the capabilities and limitations of current AI systems in health care in addition to their prevalence and regional differences. Several criteria and requirements deemed necessary for the successful implementation of AI systems were identified, including the technology’s performance and security, smooth system integration and human-AI interaction, costs, stakeholder involvement, and employee training. However, regulatory, logistical, and technical issues were identified as the most critical barriers to an effective technology implementation process. In the future, our experts predicted both various threats and many opportunities related to AI technology in the health care sector.

Conclusions

Our work provides new insights into the current state, criteria, challenges, and outlook for implementing AI technology in health care from the perspective of AI researchers and IT professionals in North America and Western Europe. For the full potential of AI-enabled technologies to be exploited and for them to contribute to solving current health care challenges, critical implementation criteria must be met, and all groups involved in the process must work together.

Authors: Wu Jian , Ma Mingze , Li Quanman , Guo Xinghong , Tarimo Clifford Silver , Jia Shiyu , Zhou Xue , Wang Meiyun , Gu Jianqin , Miao Yudong , Ye Beizhu
Published: August 2023

BACKGROUND

COVID-19 vaccine hesitancy reduces vaccination rates, which is detrimental to building herd immunity and halting the spread of COVID-19 and its variations. Most researches have simply identified the reasons affecting COVID-19 vaccination reluctance without delving into its dynamics, which makes forecasting future trends difficult.

OBJECTIVE

This study aimed to examine the current COVID-19 vaccine booster hesitancy rate in Chinese adults as well as the dynamics of vaccine hesitancy and its influencing factors. The results of this study will have practical implications for policy responses in mainland China, and effective COVID-19 booster vaccination in specific populations.

METHODS

The web-based survey was completed by creating questionnaires and using a stratified random sampling method to collect information from adults (≥18 years old) among 2556 households in 4 geographical regions of China. We collected sociodemographic information, health status, awareness of COVID-19 and its vaccine, self-perceptions, trust in medical staff and vaccine developers, and so on. The odds ratios and 95% CI for the statistical associations were estimated using logistic regression models.

RESULTS

Overall, 6659 participants (females: n=3540, 53.2%; males: n=3119, 46.8%) responded. In total, 533 (8%; 95% CI 7.4%-8.7%) participants presented a clear hesitancy in receiving the COVID-19 booster vaccination, while 736 (11.1%; 95% CI 10.3%-11.8%) expressed hesitancy in regular booster vaccination. A higher prevalence of vaccine hesitancy in both booster vaccination and regular booster vaccination was observed among participants with a history of allergies, experiencing chronic disease, lower levels of public health prevention measures or susceptibility or benefits or self-efficiency, higher levels of severity or barriers, and lower trust in both medical staff and vaccine developers (P<.05). The females and participants with higher education levels, higher levels of barriers, lower levels of susceptibility, and lower trust in vaccine developers preferred to have attitudinal changes from acceptance to hesitancy, while people with higher education levels, lower self-report health conditions, experiencing chronic disease, history of allergies, and lower trust in medical staff and developers were all positively associated with constant COVID-19 booster hesitancy.

CONCLUSIONS

The prevalence of COVID-19 vaccine booster hesitancy is not high in mainland China. However, there is a slight increment in hesitancy on regular booster vaccination. Conducting targeted information guidance for people with higher education levels and chronic diseases, as well as improving accessibility to booster vaccination and increasing trust in medical staff and vaccine producers may be highly effective in reducing vaccine hesitancy.
Atrophic Postacne Scar Treatment: Narrative Review (Preprint)
Authors: Attia Enas
Published: August 2023

UNSTRUCTURED

Acne scarring is a frequent complication of acne. Scars negatively impact psychosocial and physical well‐being. Optimal treatments significantly improve the appearance, quality of life, and self-esteem of people with scarring. A wide range of interventions have been proposed for acne scars. This narrative review aimed to focus on facial atrophic scarring interventions. The management of acne scarring includes various types of resurfacing (chemical peels, lasers, and dermabrasion); the use of injectable fillers; and surgical methods, such as needling, punch excision, punch elevation, or subcision. Since the scarred tissue has impaired regeneration abilities, the future implementation of stem or progenitor regenerative medical techniques is likely to add considerable value. There are limited randomized controlled trials that aimed to determine which treatment options should be considered the gold standard. Combining interventions would likely produce more benefit compared to the implementation of a single method.

Authors: Sugiharto Audi , Gatmaitan Julius , Dayrit Johannes
Published: August 2023

UNSTRUCTURED

Lichen planus pigmentosus (LPP) is a condition characterized by persistent and asymptomatic brownish-black–to-blue or purple-gray pigmentation, predominantly in the face and sun-exposed areas, commonly in dark-skinned individuals. Several clinical variants of LPP have been reported. However, the ichthyosiform type of LPP has not been reported. We present a 19-year-old male patient who presented with a 7-year history of asymptomatic grayish macules; patches with fine scales on the face, trunk, and upper extremities; and grayish plaques with thick “ichthyosiform” scales on the lower extremities. The diagnosis of LPP was proven by histopathological findings on both the macular and ichthyosiform plaques. Cluster differentiation (CD) 68 stain highlights the same density of pigment-laden macrophages in both the gray macule and the ichthyosiform plaque. The cause of LPP is unknown. Transcription factor anomalies may play a role in increased keratinization of lichen planus lesions. It can be assumed that the mechanism of the altered distribution of keratinization may occur on the ichthyosiform lesions in this patient. The terminology “ichthyosiform lichen planus pigmentosus” is hereby proposed to be added to the clinical variants of LPP.

Hypertension can lead to poor quality of life, disability, and in some cases, death. Therefore, careful monitoring of blood pressure is critical. The purpose of this study was to improve the collection and utilization of blood pressure collection in a hypertension clinic. The study focused on integrating electronic systems to process incoming real-world data in out-of-office blood pressure measurements, specifically in cohorts with diabetes and hypertension. By implementing an interconnected application platform. This involved continuous monitoring of patients over twelve months and continuous monitoring by their physicians and the medical staff to provide real-time feedback. This helped patients to better control their blood pressure without making an increase in the change of medications. Our data shows that practitioners could accurately collect and process patients' blood pressure and pulse data during routine telehealth visits, enhancing the clinical management strategy. Our findings demonstrate that patients engaged in self-monitoring over one year improved their ability to accurately measure blood pressure with decreased variability in blood pressure results. In conclusion, we have proven by analyzing how often do patients monitor and its frequency and accuracy in performing data processing techniques that allow us to facilitate access to information that could be qualitatively analyzed, leading to better patient involvement in their treatment.

Authors: Liu Rui , Huang Bo
Published: August 2023

This research paper provides an in-depth discussion on the challenges faced by SRUN enterprises in China and the importance of ESG practices. Currently, the concept of ESG in China is still in its early stages, and there is limited research on ESG practices and their theoretical foundation for SRUN enterprises. These enterprises face various challenges such as complex corporate governance, lack of resources and funding, difficulties in technological and digital transformation, and rigid organizational structures and decision-making mechanisms. However, the introduction of ESG practices can improve corporate governance, reduce risks and financing costs, enhance enterprise efficiency, and promote high-quality development of enterprises. Therefore, this paper suggests that SRUN enterprises should proactively identify key issues related to ESG, choose appropriate ESG topics, and incorporate ESG concepts into their operational management to enhance their sustainability. In addition, by improving innovation and flexibility, strengthening cooperation with stakeholders, and continuously improving and monitoring, SRUN enterprises can better implement ESG practices. This research provides theoretical reference and practical guidance for SRUN enterprises to implement ESG practices, and points out the direction for future research in related fields.

Published: August 2023

Abstract: In recent years, Precision Agriculture has embarked a promising role in augmenting agricultural production and various farm mechanization. The present research was conducted to design and develop a Precision Spraying System (PSS) that is controlled by an Automatic Control System (ACS). PSS was equipped with micro-controller (NodeMCU), an analog pressure regulator, solenoid valve, diaphragm pump coupled with 12V DC motor; operated on a Iot platform BLYNK. A 3D printed full cone nozzle (0.2 mm orifice dia., cone angle of 95°) was designed to achieve desired spraying efficacy as per the canopy area and the need of the crop cultivated. Integration of PSS with ACS, intrigues a proper regulation on the valves (24V, 7.92W), the pump speed, pressure head and flow rates. The spray patternator test was conducted to evaluate the Delay Time Losses (DTL), application losses, effective spraying height and pressure. The test was conducted for 4 sets of increasing pressure (5.46, 6.24, 6.86 and 7.80 bar) and 3 sets of decreasing nozzle heights (890, 760 and 620 mm). The results revealed that the maximum average discharge collected from the Patternator tray was 0.45L/min (at pressure 7.80 bar; height 620 mm) and the minimum average discharge collected was 0.26 L/min (at pressure 5.46 bar; height 890 mm). The spray angle was found to vary from 72 to 82° and the percent (%) loss in discharge was estimated to maximum of 49.02% (at height 890 mm) and the minimum value of 11.76% (at height of 620 mm) suggesting possible wind drift with increasing nozzle height. Thus, the designed PSS is propitious to forefend all the ill effects of conventional spraying and it significantly reduces the DTL to 0.5 sec

Propiedades psicométricas del DESIT-17 para la medición de la satisfacción académica en estudiantes de Ciencias Médicas de la Universidad de Iberoamérica (UNIBE)
Authors: Román-Quirós Rafael
Published: August 2023

Las universidades tienen una crucial responsabilidad en su papel de formación social y profesional, además de ser vehículos de movilidad social en el actual y difícil contexto socioeconómico global. Por esta razón, es especialmente relevante no solo el contar con instrumentos psicométricamente adecuados, sino también de fácil aplicación respecto a la calidad de la educación. El objetivo del artículo es explorar las propiedades psicométricas de un instrumento de satisfacción académica (SA) desarrollado a partir del cuestionario de autoevaluación del Sistema Nacional de Acreditación de la Educación Superior (SINAES), empleado por las universidades que procuran estar acreditadas en Costa Rica, junto con el aporte de información relevante encontrada en este caso particular. El instrumento fue aplicado a 226 estudiantes de Ciencias Médicas de la UNIBE de forma presencial durante el primer cuatrimestre del año 2021 en San José. Como resultado, tras un análisis factorial exploratorio se obtuvo el DESIT-17, un instrumento para medir SA a partir de cuatro factores de satisfacción: con la atención docente (SAD), con el equipo (SAE), con los servicios (SAS), y con los aspectos científicos y tecnológicos de la formación (SACT). Adicionalmente, se encontró que a mayor tiempo transcurrido de haber ingresado a la carrera, menor el nivel tanto de SA general, como de sus factores, a la vez que la edad no muestra relación con la SA, excepto en lo que atañe a la SAS que resulta menor en estudiantes de mayor edad. Por último, se encontró una SAE menor en el 16.9% de estudiantes que reportan trabajar.

A cidade subalterna representada nos romances da saga do cacau de Jorge Amado: imaginário urbano sobre "outra" Ilhéus nas décadas de 1920 e 1930
Authors: Santos Igor Campos
Published: August 2023

A Cidade de Ilhéus, no Sul da Bahia, passou por processos de modificações urbanas que motivaram a formulação de representações acerca de seu espaço citadino referentes às décadas de 1920 e 1930. Jorge Amado, romancista grapiúna, em suas narrativas da saga do cacau, recriou o ambiente urbano do período, destacando, também, os espaços subalternizados e seus habitantes. O objetivo desta pesquisa é apresentar essas representações socioespaciais presentes na ficção, buscando, assim, a reconstrução de um imaginário urbano que abarque sujeitos e lugares silenciados ou esquecidos da memória urbana de Ilhéus, bem como outras representações possíveis para a cidade.
“Mulheres Públicas”: sexualidades desviantes e prostituição no Alto Sertão da Bahia (Caetité, 1900-1940)
Authors: Almeida Miléia Santos
Published: August 2023

A análise de processos-criminais para identificar as experiências de mulheres pobres diante das leis penais no alto sertão da Bahia revela uma série de fragmentos de suas vidas e os discursos médico e jurídicos que compunham as narrativas dos documentos no início do século XX. Emergem desses processos as mulheres definidas como “meretrizes, públicas ou de vida livre”, sobretudo nas localidades consideradas de “baixo meretrício” no município de Caetité. Compreendemos que, diante do projeto moralizador republicano, a prostituição representava, ao mesmo tempo, uma ameaça e um mal necessário, sendo alvo das estratégias de “civilização dos costumes” até mesmo nas regiões mais interioranas. Por sua vez, as intenções moralizantes das elites brasileiras se chocavam com “outros padrões de moralidades” de homens e mulheres pobres sertanejas que vivenciavam as sexualidades em desacordo com os padrões morais dominantes. Além dos processos, é possível perceber discursos sobre a prostituição em Caetité em outras tipologias documentais, sempre mediadas pelo olhar vigilante das elites sertanejas, que aqui são analisadas sob a perspectiva teórica da história das mulheres e das relações de gênero.
A PSICODINÂMICA DO TRABALHO E O SOFRIMENTO PSÍQUICO DOS PROFISSIONAIS DA SAÚDE

Com o processo de industrialização, os modos de produção se modificaram para aumentar a velocidade de produção e otimizar o tempo de trabalho. Contudo, o sujeito trabalhador foi anulado nesse contexto. Para Christophe Dejours, o sofrimento psíquico dos trabalhadores, é representado, principalmente, por dois sintomas: a insatisfação e a ansiedade. A insatisfação pode originar-se a partir de duas fontes: do “conteúdo significativo” e do conteúdo ergonômico do trabalho. A partir de suas teorias sobre como o trabalho afeta a vida humana o autor elaborou uma proposta de intervenção: a psicodinâmica do trabalho, que tem por objetivo intervir em situações concretas de trabalho, compreender os processos psíquicos envolvidos e formular avanços teóricos e metodológicos reproduzíveis a outros contextos. Ela busca estudar os aspectos vivenciados pelos trabalhadores ao longo do processo laboral, a partir de situações vivenciadas no trabalho, tais como: mecanismos de cooperação, reconhecimento, sofrimento, mobilização da inteligência, vontade, motivação e estratégias defensivas. A psicodinâmica do trabalho também define o trabalho como um elemento central na construção da saúde, na identidade dos indivíduos, e ressalta que sua influência vai além da jornada de trabalho propriamente dita e se estende para todos os âmbitos da vida familiar. A hipótese da psicodinâmica do trabalho considera que se os sujeitos transformam e/ou elaboram suas vivências no trabalho, eles conseguirão conceber uma análise mais precisa e aprofundada da organização do trabalho, e em consequência disso, estarão mais aptos a transformar a organização do trabalho. O mesmo aplica-se aos profissionais de saúde, uma vez que as profissões da área da saúde estão em terceiro lugar como campeãs em gerar estresse, por estarem ligadas à dor, doença e morte. Portanto, entende-se que, devido a sua relevância na saúde do trabalhador, no caso do profissional da saúde, e na qualidade do cuidado prestado, o sofrimento psíquico necessita ser considerado e estudado pelos pesquisadores, sendo de fundamental importância que o arcabouço de conhecimentos acerca do tema seja primeiramente explorado. A palavra dos trabalhadores deve ser ouvida (em mais de uma ocasião), recebida e considerada, a fim de que os sujeitos consigam transformar e elaborar suas vivências de trabalho de modo a promover sua saúde e prestar uma assistência de qualidade.

Numerical Analysis of Waste-Based Thermal Energy Storage System for CSP Plants
Authors: Koçak Burcu , PAKSOY Halime
Published: August 2023

Thermal energy storage (TES) is an enabling system that provides
uninterrupted energy from concentrated solar power (CSP) plants.
Packed-bed TES systems have great opportunity to significantly enhance
the cost-effectiveness, efficiency and sustainability of CSP plants by
employing an affordable and sustainable packing material. The objective
of this study is to design a packed bed TES system with a maximum
storage capacity of 40 kWh, specifically tailored to store heat within
the temperature range of 290 – 565 °C, thereby making it suitable for
integration into CSP plants. Performance and thermal behavior of
demolition waste-based packed-bed TES system was assessed through
numerical analysis. The results demonstrate that a high discharging
efficiency of 96.7% was achieved when the HTF flow rate was set at 300
kgh . However, it is important to note that at lower
HTF flow rates, heat loss increases, leading to a decrease in
discharging efficiency to 93.7%. The experiment also revealed a uniform
thermal gradient within the packed-bed TES system, up to a fluid flow
rate of 300 kgh . It is worth mentioning that lower
flow rates can further improve the stratification effect; however, they
may also result in increased heat loss and reduced storage capacity.
Based on these findings, an optimal flow rate range of 100-200 kgh
is recommended to achieve the best performance for
the packed-bed TES system.

This paper describes a 5-year-old Chinese girl who presented with acute
fever and epistaxis. After admission, relevant ancillary tests indicated
the presence of hemophagocytic lymphohistocytosis (HLH) and the
combination of EBV infection in this patient. Pathology of the cervical
lymph node biopsy and bone marrow flow cytology examination indicated
systemic EBV-positive T-cell lymphoma of childhood (STCLC), and a
diagnosis of STCLC combined with HLH was clear. Although the girl was
clearly diagnosed within a few days and treated with chemotherapy and
symptomatic support, she eventually died on the 6th day after admission
due to progressive worsening of her disease. We also describe the
possible pathogenesis of STCLC combined with HLH through a search of the
relevant literature.
