Information needs of prospective postgraduate students
Authors: Konyana Samkele
Published: March 2022

The complex application process at the postgraduate level became a major blamer for poor doctorate enrolments. The complexity in the communication messages made it difficult for prospective postgraduate students to absorb information effectively. The proposal by the government to increase masters' and doctorate enrolments at universities requires universities to cater to the needs of customers whose preferences and expectations change continuously. The research upon which this paper was based was aimed at identifying the information needs of prospective postgraduates at public universities. The study design is quantitative, employing a descriptive technique and cross-sectional method. For the empirical study, a non-probability sampling method was utilized to obtain data from a sample of 116 masters’ and doctorate students. Descriptive statistics described the main features of the collected data through frequencies, tables, and bar charts. Inferential statistics were used to determine relationships between variables and test the significance, and reliability of the findings. Emphasis on university processes and specific aspects of the expected and augmented product were found. Interestingly, the importance attached to getting information about economic incentives significantly outweighs the importance attached to receiving information about the actual product. The results of this study affirm the assertion that the postgraduate market is unique and has unique information needs. The results provide universities with a guideline to identify the information needs of prospective postgraduate students applying for master's and doctorate studies at public universities.  The study limitation is that it encompasses only a small number of registered master’s and doctoral students in KwaZulu-Natal, limiting the possibility of generalizing the results to all prospective postgraduate students in South Africa.

Published: March 2022

The purpose of the study was to evaluate the challenges encountered by the South African Police services (SAPS) when dealing with 4IR. The study used a qualitative approach because the study wished to obtain practical answers to the problem, as well as the explanations provided by participants who are practitioners in the field and a total of forty (40) police officers were selected to participate in the study. The researcher followed purposive sampling. The reasoning for using purposive sampling is that it is based on the assumptions that the participants have in-depth knowledge in the chosen areas of the study.  The findings of the study are that the local police stations of SAPS Gauteng are where many victims of crimes emerging from 4IR get turned away by officials who do not understand the various cybercrimes, the applicable charges, or how to go about escalating the matter. The study further found that the Government policy seems to prioritize statistics, quotas, and the images they reflect as opposed to the true situation hence crimes emerging from 4IR are poorly understood, prevented, and investigated. The study recommends that IT capacity and resources within SAPS have to be developed in order to ensure that the SAPS in Gauteng province is able to investigate, combat and trace the sophisticated crimes caused by the criminals. The SAPS needs to allocate funds to buy IT equipment, software and headhunt personnel who have skills, knowledge, and capacity to curb, investigate and combat 4IR crimes.

Published: March 2022

The purpose of this study is to see whether there is an effect of the implementation of good corporate governance, firm size, and financial performance on firm value. And the results are known if the implementation of good corporate governance has a positive effect on firm value which indicates that the implementation of good corporate governance in Indonesia has a good impact on the development of firm value, in contrast to firm size and financial performance which have a negative effect on firm value, which is known if assets and profits are high. compared best with low firm value, and vice versa. On the one hand, financial performance can be an intervention variable for good corporate governance and firm size on firm value in a positive direction, which means that if firm profits can have an influence on the relationship between firm size and good corporate governance, the firm value will increase. From these objectives and results, it is recommended for further researchers to explore the indicators that exist in each member to find out valid findings by reviewing various aspects.

Risks to credit access in a developing economy
Authors: Inyang Uduakobong
Published: March 2022

Governments in developing economies are continuously seeking ways to increase the number of people that have access to formal financial services. However, literature on why households in developing economies are excluded from the formal credit sector is scarce. Thus, this study examines the link between household characteristics and the choice of credit provider using unique household-level primary data from the Niger Delta region. A binomial logistic regression model based on relevant household characteristics is developed for estimation. The results show that the number of dependents and income of a household, as well as education level and age of household head, is relevant in understanding the choice of the credit provider. Strikingly, the finding that the probability of borrowing from the informal sector increases with household distance from a formal lender at a decreasing rate suggests the significance of cost associated with traveling to the nearest bank on the choice of a lender and the presence of information asymmetry in the credit market of the region. Overall, the study raises important implications to inform credit market policies and practices in the region.

Authors: Etrata Antonio Jr Estrada , Raborar Jackie Lou
Published: March 2022

Entrepreneurs play pivotal roles that affect the economy. These roles are job creation, wealth generation, economic growth, and innovation. According to WorldBank data, they account for around 90% of enterprises and more than half of all jobs in the globe. In emerging economies, formal SMEs account for up to 40% of national income (GDP). The prolonged effects of the COVID-19 pandemic which resulted in job losses have encouraged even the Filipino Generation Z to engage in entrepreneurial activities. This supports various studies conducted by research firms recently that 54% of Generation Z wanted to start their own business venture. Thus, this research aims to determine the influence of entrepreneurial attitude, social valuation, entrepreneurial skills, and entrepreneurial knowledge on entrepreneurial intention.  There were 110 Generation Z respondents who answered the adopted survey questionnaire. The researchers were able to secure permission from the original author to use the research instrument. The research utilized a quantitative research design primarily descriptive-correlational. The data were processed using regression analysis to test the relationship of variables.  The regression results preceded the acceptance of the 4 hypotheses which means that entrepreneurial attitude, social valuation, entrepreneurial skills, and entrepreneurial knowledge significantly influence entrepreneurial intention.  The results will be considerably useful to academics to promote entrepreneurship from high school to college level, to future entrepreneurs in identifying the factors that influence entrepreneurial intention, to the government and its regulators for policy development, and to researchers who plan to expand the literature on the entrepreneurial mind.
Psychosocial and economic challenges faced by young fathers in assuming parental responsibilities in South African communities
Authors: Matlakala Frans Koketso , Rantho Katlego Magdeline , Maluleke Witness
Published: March 2022

The father’s involvement in their children’s life is often defined by economical and psychological support, those without adequate financial muscle are often denied 1) parental contact and 2) responsibilities. The noted unjustified perceptions fail to contemplate historic socio-economic and psychosocial factors affecting fathers’ roles and related expectations. Therefore, the objective of this study was aimed at accentuating psychosocial and economic challenges faced by young fathers in assuming parental responsibilities, focusing on South African case studies. The applied methodology was based on ‘non-empirical research design: Systematic Review,’ documentary sources were qualitatively [Purposively] sampled from the search engines such as ‘Google scholar, South African Electronic Thesis or Dissertation (ETD) portal, Jstor, Sabinet, and EbcoHost,’ using keywords/phrases related to the subject under research to filter relevant data, restricted to 2003-2022. The inductive Thematic Content Analysis (TCA) analyzed the collected data. The primary finding of this study revealed that [Some] young fathers are faced with parental exclusions owing to the financial instability of compensating and supporting them. Moreover, they also experience psychological distress and resort to criminal activities to find means of supporting their children. The underlined conclusion suggests that society should allow fatherly responsibilities to be catered on children without placing more pressure on them (Fathers’), their financial standards should be respected at all costs. Programs strictly advocating for children’s contact with their non-residential fathers to encourage their [Fathers] positive involvement and focus on children’s needs across South African communities should be urgently staged.

Published: March 2022

The study reports findings of an investigation on the effect of emergent capability derived from an organization development (OD) program on the effect of the OD on realized performance in a National Police Service public sector reform program in Kenya. The study considered how four components of the OD process were realized from the reform program and determined the level of emergent capability that resulted from the OD components. Primary data was obtained from a sample of 294 senior officers in job groups PG5-PG11. The study finds that the level of OD realized from the reform program was rated at a moderate level and contributed to an equivalent level of emergent capability of the form of organization health. OD has a significant positive effect on the emergent capability and performance while the emergent capability has a positive effect on performance and partially mediates the effect of OD on performance. The study calls on practicing managers to consider integrating the OD process with the strategic management process from initiation to the end of the process. Future research is called upon to consider expanding both the conceptual and methodological scopes adopted in this study to enhance the generalizability of the findings.

Published: March 2022

Practical activity is an integral part of science learning process, including biology. However, during distance learning in the era of COVID-19 pandemic, biology practical activities are often not carried out due to a number of obstacles. This study aims to explain the various obstacles or problems experienced by teachers when conducting biology practical activities during the COVID-19 pandemic. The data of this study were collected by distributing questionnaires to 54 teachers who teach natural sciences in Junior High Schools and biology in Senior High Schools in West Java Province with different lengths of teaching experience. The results showed that the teachers experienced several problems, such as limited allocation of learning time during distance learning, the difficulty of designing practical activities that could be carried out independently by students at home, and the difficulty of finding alternative tools and materials at students' homes. To overcome these obstacles, the teachers has made various efforts and the most chosen were asking students to watch videos of practical activities or simplifying the practical activities so that they can be carried out independently by students at home.Abstrak Kegiatan praktikum adalah bagian tak terpisahkan dari proses pembelajaran sains, termasuk biologi.

DETERMINATION OF OPTIMISED PICK-UP AND DROP-OFF LOCATIONS IN TRANSPORT ROUTING – A COST DISTANCE APPROACH
Authors: HAHN Armin , FRÜHLING Wiard , SCHLÜTER Jan
Published: March 2022

With the emergence of dynamic passenger transport systems, such as demand-responsive transport (DRT) and ride-sharing without predetermined stop locations as used for static bus routes, accurate routing for these flexible door-to-door transport services is needed. Routing between two addresses requires the assignment of addresses to suitable, so-called snapping points as reference points on the road network. Therefore, many conventional routing machines use perpendicular distance to identify the nearest point on the road network. However, this technique tends to produce inaccurate results if the access to a building is not reachable from the road segment with the shortest perpendicular distance. We provide a novel approach to identify the access to buildings (paths) based on remote sensing data to obtain more reasonable stop locations for passenger transport. Multispectral images, OpenStreetMap data, and light detection and ranging (LiDAR) data were used to perform a cost distance analysis based on vegetation cover, building footprints, and the slope of the terrain to identify such optimised stop locations. We assumed that the access to buildings on the shortest route to the building’s entrance consists of little vegetation cover and minimal slope of the terrain; furthermore, the calculated path should not cross building footprints. Thus, snapping points on the road network can be determined based on the most likely path between a building and the road network. We validated our results based on a predetermined ideal snapping area considering different weightings for the parameters slope, vegetation, and building footprints. The results were compared with a conventional routing machine that uses perpendicular distance. This routing machine shows a validation rate of 81.4%, whereas the validation rate of our presented approach is as high as 90.3%. This new approach provides increased accuracy and better comfort for flexible passenger transport systems.

This article presents the results of an extensive questionnaire survey focused on changes in the transport behaviour of the population of the Czech Republicimmediately after the government’s announcement about the measures implemented to prevent the spread of COVID-19. The questionnaire aimed to determine the changes in the use of the mode of transport for regular travel to work, school, or for shopping, as well as to determine the changes in the frequency of these travels according to monitored socio-demographic groups of inhabitants and specified size groups of settlements. This article contains a statistical evaluation of these changes in the transport behaviour of the population using sophisticated statistical tools. A method is proposed for estimatingthe number of passengers in public transport using a linear regression model based on the data from conducted transport behaviour survey.In this paper, the Data envelopment analysis (hereinafter referred to as DEA method) within the case study in the South Bohemian Region is also used to determine whether the COVID-19 measures have reduced the efficiency of public transport.
ANALYSIS OF THE SHARE OF NATURAL GAS IN THE TOTAL FUEL SUPPLY DOSE ON THE COMBUSTION PROCESS IN A CRDI ENGINE
Authors: WIERZBICKI Sławomir , BORUTA Grzegorz , KONIECZNY Łukasz , ŁAZARZ Bogusław
Published: March 2022

Natural gas is one of the potential combustion engine fuels whose proportion in the overall energy balance is expected to increase. Owing to some of its properties, its use requires a dual-fuel supply system; thus, the use of natural gas as a fuel for diesel engines is currently limited. Systems that supply gas fuel to diesel engines do not usually interfere with the engine control system. This solution significantly reduces system-installation costs. However, as demonstrated in the present study, it considerably changes the course of the combustion process, which increases thermal and mechanical loads. In this case, the combustion process can be controlled by changing the liquid fuel injection pressure or advancing the injection angle. This, however, requires interference with the engine control system.

Published: March 2022

This study aimed to adjust the rail passenger car running gear parameters by adapting them to independently rotating wheels. The most important aspect was the safety of the passenger car running in terms of derailment; thus, the values of the Nadal criterion were calculated first. Another aspect to consider is passenger comfort based on the values of Sperling’s comfort index according to the rail passenger car speed. The modes of suspension behaviour during operation were considered in two typical conditions: on a straight track section and on a curve with a 200-m radius. Calculations were performed using Universal Mechanism software. The results are interpreted in the paper, and the final conclusions of this study are given.

ResumenLos procesos de gentrificación han ido evolucionando y mutando sus características. Madrid, en tanto que una ciudad de rango global está expuesta a estos cambios, uno de cuyos principales peligros reside en su detección temprana para la adopción de contramedidas que palíen sus efectos negativos. Una de las características de los nuevos procesos es su extensión fuera de los ámbitos centrales históricos de las ciudades, que concentran las principales actividades económicas, culturales, turísticas, de ocio, etc, a ámbitos territoriales previamente no afectados; en el caso de Madrid, fuera de la Almendra Central. Este artículo explora la hipótesis nuevos procesos de gentrificación en nuevas “centralidades ampliadas”, que en este caso se acotan a los distritos al sur del Rio Manzanares, mediante la aplicación de nuevas metodologías, con el uso de Big Data y datos abiertos, en combinación con aspectos cualitativos, para la evaluación, en la medida de los posible, de estos nuevos procesos, identificando los nuevos ámbitos afectados, y exponiendo las limitaciones de estos análisis cuantitativos con los datos accesibles en la actualidad.AbstractGentrification processes have evolved and changed their characteristics.

Los 10 principios del Nuevo Urbanismo Americano : un análisis de las sedes de grandes empresas tecnológicas de Silicon Valley = The 10 Principles of New Urbanism : An Analysis of Silicon Valley’s Big Tech Headquarters
Authors: Alexander Marroquin Daniel
Published: March 2022

ResumenEl Nuevo Urbanismo americano es un enfoque de planificación y desarrollo urbano en EEUU, basado en cómo se han construido ciudades y pueblos antes de la invención del automóvil. Calles peatonalizadas, viviendas y tiendas en las proximidades, parques y espacios públicos accesibles junto a oficinas, escuelas y edificios gubernamentales. Cada uno contribuyendo a la dinámica de un tejido urbano de alta calidad. Los 10 Principios del Nuevo Urbanismo son un conjunto de principios aplicables a cualquier proyecto urbano, de cualquier escala, desde un edificio hasta la escala metropolitana. A continuación, os expongo un sistema de puntuación que he creado para evaluar y clasificar en un ranking las sedes internacionales de las grandes empresas tecnológicas de Silicon Valley para comprobar si estas grandes empresas tecnológicas contribuyen al Nuevo Urbanismo de ciudades peatonalizadas y densas, o favorecen la dispersión suburbana, dependiente del uso del automóvil.AbstractNew Urbanism is an American urban planning and development approach based on the principles of how urban areas used to be built before the invention of the automobile. Cities were built as dense urban environments with lots of life and vibrancy at street level with a mix of homes, shops and restaurants next to offices, schools and government buildings, surrounded by parks and public spaces, each one contributing to the dynamics of a high-quality urban fabric. The 10 Principles of New Urbanism are urban planning guidelines that can be applied to any project site of any size, from the small scale of a single building to the large metropolitan scale. I have created a point system to evaluate the international headquarters of Silicon Valley's Big Tech giants to see if these global tech companies are contributing to automobile-based suburban sprawl or to a pedestrian-friendly New Urbanist environment.

Published: March 2022

ResumenLa implementación de políticas públicas se ha convertido en un gran reto para los gobiernos. A ello no es ajeno la gestión de una peatonalización que, como toda política pública, busca satisfacer necesidades demandadas por sus ciudadanos. En ese sentido, en el presente trabajo, se busca identificar la mejor manera de abordar este tipo de políticas urbanas, teniendo en cuenta los diversos elementos o agentes que la conforman y la multiplicidad de relaciones que se generan dentro de este sistema funcional. Para lo cual se ha revisado el estado del arte, y, además, analizado algunos casos de peatonalización a través del uso de histogramas. Luego, en base al conocimiento adquirido proponer un modelo conceptual y una diagramación temporal para casos genéricos de peatonalización. Finalmente se concluye que, a pesar de los intentos de los urbanistas por tratar con políticas peatonales, estos resultan ser de naturaleza perversa, es decir, son problemas complejos.AbstractThe implementation of public policies has become a great challenge for governments. The management of pedestrianization, which—like any public policy—seeks to satisfy the needs of citizens, is no stranger to this challenge. This paper seeks to identify the best way to approach this type of urban policy, taking into account the various elements or agents that make it up and the multiplicity of relationships that are generated within this functional system. Some cases of pedestrianization have been analyzed through the use of histograms, and based on the knowledge acquired, we propose a conceptual model and a temporal diagram for generic cases of pedestrianization. We conclude that, despite the attempts of urban planners to deal with pedestrian policies, they turn out to be of a perverse nature; they are complex problems.

En una sociedad globalizada se hace necesario abrir las instituciones educativas al entorno y fomentar la participación ciudadana de los jóvenes en el desarrollo sostenible. Una forma de implicar a los jóvenes en el desarrollo sostenible es a partir de las salidas de campo que les permiten estar en contacto con su entorno; para ello se hace necesario plantearse metodologías de enseñanza y aprendizaje que permitan implicar a nuestro alumnado y a su vez facilitarles un papel activo en la sociedad. Con el auge de las tecnologías digitales, el futuro de la educación ha de conseguir implicar a los jóvenes en los municipios y darles voz para hacerles partícipes en el mundo que les rodea. En este artículo presentamos una propuesta didáctica basada en el storytelling digital usando el vídeo para implicar a los niños y jóvenes en el desarrollo sostenible durante las salidas de campo. La propuesta se ha experimentado en un instituto de la provincia de Girona y se aborda desde un enfoque de investigación cualitativa. El análisis de los resultados obtenidos a partir de la experimentación de la propuesta didáctica nos muestra el potencial del storytelling digital para sensibilizar e implicar a los jóvenes en el desarrollo sostenible.

Published: March 2022

Las aplicaciones móviles que incorporan contenidos relacionados con la salud han sido de los recursos tecnológicos que más se han extendido en los últimos años, sobre todo a raíz de la situación provocada por el coronavirus. En España, muchas ya han sido sometidas a procesos de regulación de calidad y fiabilidad a través de iniciativas acreditadoras. Además, se ha comprobado que la gamificación en este tipo de tecnología es efectiva para generar conductas saludables en la población joven. Este estudio se centra en conocer cuáles de ellas cuentan con una certificación de calidad en nuestro país y están orientadas a la promoción de hábitos saludables en niños/as y jóvenes. Se ha llevado a cabo una revisión exhaustiva de los portales de salud de carácter gubernamental y no gubernamental en los cuales quedan recogidos los sellos, los distintivos o las etiquetas de calidad como iniciativas acreditadoras en el campo de la salud. Entre los resultados, resaltar que el número de aplicaciones destinadas a menores y a adolescentes, que además integren elementos ludificados y certificadas, es muy escaso y menor en comparación con aquellas dirigidas a adultos, y ello, a pesar de la relevancia que pueden tener para su salud y bienestar.

Published: March 2022

Three species of the genus Phyllodistomum Braun, 1899 are identified infecting marine teleost fishes from Sinop coast (southern Black Sea, Turkey). Those are Phyllodistomum acceptum from Parablennius sanguinolentus; Phyllodistomum crenilabri from Symphodus tinca and Symphodus ocellatus; and Phyllodistomum sp. from Gobius cruentatus. Standard parasitological investigation methods were implemented, and morphological diagnostic features of these species were studied in detail under both light microscope and scanning electron microscope. The measurement data of all morphological diagnostics are provided; photomicrographs of each part of the parasites are presented. Infection prevalence and intensity values are given, as well as morphometric data for each parasite species. This research is the first on Phyllodistomum sp. presence in Gobius cruentatus. Moreover, this study is the first one, in which the tegumental surface of P. acceptum and P. crenilabri was examined by scanning electron microscopy.
La memoria estética del videojuego
Authors: Venegas Ramos Alberto , Gutiérrez Manjón Sergio
Published: March 2022

El videojuego como artefacto cultural traspasa su concepción lúdica construyendo sus propias funciones de socialización y representación como el resto de los medios de comunicación. Entre estas funciones se desarrolla la puesta en escena de una determinada memoria estética que alude a referentes intertextuales compartidos en otros medios. A través del análisis de contenido de Blasphemous, videojuego creado por el estudio sevillano The Game Kitchen, podemos analizar las fuentes de dicha memoria con el objetivo de examinar cómo se reproducen las tradiciones y ritos de Andalucía en el universo mediático y globalizado del videojuego. Así pues, Blasphemous, como dispositivo cultural, adopta una serie de señas identitarias que representan dentro de su iconografía la ciudad de Sevilla, la religiosidad cristiana barroca y la cultura andaluza. De esta forma, Blasphemous adapta estas referencias a una propuesta artística basada en los nuevos medios digitales y virtuales en clave de videojuego cuyo fin es la diversión, la seducción y la rentabilidad al ser un producto de masas dotándolo de nuevos significados.

Authors: Chrisendo Daniel , Jalava Mika , Deryng Delphine , Heino Matias , Kummu Matti
Published: March 2022

In recent years, many scientific studies have analyzed potential solutions and opportunities to improve food systems towards sustainability. Various socioeconomic factors play crucial roles in determining the successful or unsuccessful implementation. Yet, systematic reviews, which provide a comprehensive picture of food systems-socioeconomic relationships, are still lacking. Such studies could integrate crucial information, particularly important for stakeholders who rely on scientific articles when making decisions. Therefore, we aim to systematically screen and review existing literature to draw common patterns of feasible socioeconomic measures essential for sustainable food systems. The objective of this protocol is to outline the methods we use and to avoid bias, especially when screening relevant articles.

Background: Similar to other African countries, life expectancy of people living with HIV infection has improved due to access to antiretroviral therapy (ART) in Rwanda. However, both HIV infection and use of ART are associated with cardiovascular disease (CVD) risks, due to adverse changes in some biochemical markers, causing dyslipidemia and other metabolic imbalances. Biomarkers for CVD risk in HIV-infected individuals taking ART, has not been well characterized in Rwanda. We evaluated the association between the use and duration of ART and biomarkers of CVD risk among HIV infected adults in Rwanda. Methods: A total of 150 participants (18-45 years) from HIV clinics in public Health Center in Kigali included n=30 HIV-uninfected (HIV-) and n=120 HIV-infected (HIV+) adults. Among the HIV+ adults, n=40 participants were ART-naïve. Cross-sectional data were collected on health-related behaviors and biochemical markers of CVD risk. We compared CVD-related biochemical markers between HIV-, HIV+ ART-naïve and HIV+ on ART groups. Results: The majority of participants were women (60%) and HIV- were younger (35±6 vs. 31±6 years). Total cholesterol and triglycerides concentrations were associated with ART usage. Serum triglycerides concentrations were lower in HIV+ ART-naïve compared to HIV+ on ART (76.6±38.9 mg/dl vs. 85.0±38.3 mg/dl; p< 0.01). While total cholesterol concentrations was higher in HIV+ on ART than HIV+ ART-naïve (136.0±45.1 mg/dl vs. 130.0±36.5 mg/dl; p<0.04), HDL-C was higher in those taking ART (68.7±30.0 mg/dl vs. 55.0±25.7 mg/dl; p=0.02) among HIV+ on ART for 0-6 months and 7-12 months respectively. Conclusion: Higher serum total cholesterol and triglycerides were associated with use of ART in young adults with HIV. Although these values were within the upper limits of normal, our findings suggest early alterations in biomarkers of cardiac risk. These findings underscore the need for early evaluation of lipid profiles as biomarkers of cardiovascular disease risk, to effectively monitor how ART may contribute to cardiovascular disease and deter treatment programs in African countries.

Background
Paralytic ileus is common in patients with septic shock, which causes high morbidity and mortality. Enteric neurons and enteric glial cells (EGCs) regulate intestinal motility, but little is known about their interaction in endotoxemia. We aim to investigate whether reactive EGCs have harmful effects on enteric neurons and participate in intestinal motility disorder in mice during endotoxemia.
Methods
Endotoxemia was induced by lipopolysaccharide (LPS) intraperitoneal injection in mice. And fluorocitrate (FC) was administered before LPS injections to inhibit the reactive EGCs. The effects of reactive EGCs on intestinal motility were analyzed by motility assays in vivo and colonic migrating motor complexes (CMMCs) ex vivo. The number of enteric neurons was evaluated by immunofluorescent staining HuCD, nNOS and ChAT in vivo. In addition, we stimulated EGCs with IL-1β and TNF-α in vitro and cultured the primary enteric neurons in the conditioned medium, detecting the apoptosis and morphology of neurons through staining TUNEL, cleaved Caspase-3 protein and Anti-β-III tubulin.
Results
Intestinal motility and peristaltic reflex can be improved by the inhibition of reactive EGCs in vivo. There is an increased density of the neuronal population in the colonic myenteric plexus significantly while the reactive EGCs are inhibited, especially the nitrergic neurons. In vitro, the enteric neurons cultured in the conditioned medium of reactive EGCs had significantly more apoptotic rate and less dendritic complexity and number of primary neurites.
Conclusion
Reactive enteric glial cells participated in paralytic ileus by damaging nitrergic neurons during endotoxemia. It could provide a novel therapeutic strategy for intestinal motility disorders during endotoxemia or sepsis.

Published: March 2022

Background:Cervical spondylotic myelopathy patients with multiple segments are usually treated with surgery via the posterior approach, but expansive open laminoplasty (ELAP) often results in heavy, rigid, and acid bilge feelings in the neck, shoulder, and back, collectively known as axial symptoms. Objective: To evaluate the effect of modified posterior cervical ligament complex reconstruction and single-door laminoplasty with titanium plate fixation on postoperative axial symptoms in patients. Methods: We conducted a retrospective study including 132 cases of cervical spondylotic myelopathy at our institute from June 2016 to March 2018. Gender, age, operation time, intraoperative blood loss, post-operative drainage volume, and follow-up time, Visual analogue scoring (VAS), cervical curvature index (CCI) and the cross-sectional area of the posterior cervical muscles of the two groups were recorded. Results: There was statistical significance in the incidence of axial pain 3 months after surgery (P = 0.001), 6 months after surgery (P = 0.006), and 1 year after surgery (P = 0.015). Compared to group b, the VAS score in group A was decreased 1 week (P <0.0001), one month, 3 months (P=0.0001), 6 months(P=0.0076), and 1 year(P=0.0085) after surgery. The CCI and the posterior cervical muscle area also differed significantly between the two groups (P < 0.0001).Conclusion: Modified single open-door laminoplasty could relieve cervical axial pain in patients with cervical spondylotic myelopathy.
Evidence for an Expanded Hypertension Care Cascade in Low- and Middle-Income Countries: A Scoping Review

Published: March 2022

Background
With nearly 90% of annual hypertension-related deaths occurring in low- and middle-income countries (LMICs), there is an urgent need to measure the coverage of health services that effectively manage hypertension. However, there is little agreement on how to define effective coverage and the existing hypertension care cascade (hypertension prevalence, percent aware, percent treated, and percent controlled) does not account for the quality of care received by patients. This study reviews definitions of effective coverage and service quality for hypertension management services and proposes an expanded hypertension care cascade to improve measurement of health systems performance.
Methods
A systematic scoping review of literature published in six electronic databases between January 2000 and October 2020 identified studies that defined effective coverage of hypertension management services or integrated dimensions of service quality into population-based estimates of hypertension management. Findings informed an expanded hypertension care cascade from which quality-adjusted service coverage can be calculated to approximate effective coverage.
Results
The review identified 20 relevant studies, including 8 that defined effective coverage for hypertension management services and 12 that reported a measure of service quality in a population-based study. Based on commonly reported barriers to hypertension management, new steps on the proposed expanded care cascade include (i) population screened, (ii) population linked to quality care, and (iii) population adhering to prescribed treatment.
Conclusion
There is little consensus on the definition of effective coverage of hypertension management services, and most studies do not describe the quality of hypertension management services provided to populations. Incorporating aspects of service quality to the hypertension care cascade allows for the calculation of quality-adjusted coverage of relevant services, enabling an appropriate measurement of health systems performance through effective coverage.
