To meet the optimal nutritional for school children needs better food supplies in school meand or breakfast               In this community service activities, the team designed the school meal report book for scoring the performance of school meal.The food report book is a communication media between teaches and parents on children school food. This book contains seven item to measures, namely 1) type of foods, 2) type of nutritent, 3) processing, 4) meal serving, 4) consumption, 5) consumption, 6) drinks and 7) meal box Every day teachers observe meals dan giving scoring. Number of children used meal report book is 60 children from five classes. Each children have one meal report book. The activities of using meal report book is six weeks. Each item of meal performance was scored into three categories;  6, 8 and 10. Example if  types of foods only 1 or 2 types such as rice and fish it is scored 6. If 3- 4 types it is scored 8 and if more than 4 types the scoe is 10After six weeks using the meal report book, there were positive changes in several items of food performance.Among seven items of food performance, the average score of serving and type of drinks (7.0) are lower than other items. In week 2, five among seven items had low score. Only consumption and meal box had higher scores. This trend of scores also happened in week 3 and week 4. In week 5 and 6, only the score of drinks was low (7.5), while other variable had higher scores; types of foods 7.9, servings 7.9, types of nutrient 7.9 and score for consumption was the highest 9.0.Introducing meals report can affect the performance of school meals in processing, serving and nutrient contents
Minority Tax on Medical Students: A Review of the Literature and Mitigation Recommendations
Authors: Betancourt Renée M. , Baluchi Donna , Dortche Kristina , Campbell Kendall M. , Rodríguez José E.
Published: March 2024

Background and Objectives: Accreditation standards for MD- and DO-granting institutions require medical schools to recruit a diverse student body and educate students about diverse groups of patients. The minority tax is a summary of responsibilities assigned to racial and ethnic underrepresented faculty to achieve diversity, equity, and inclusion in medical institutions in addition to their typical academic workload. This article provides a narrative review of medical students’ experiences of the minority tax and recommendations on how medical educators can support an equitable learning environment by eliminating the minority tax.
Methods: We searched the PubMed, Web of Science, and Scopus databases, Google Scholar, and medical society websites, blogs, and fora for terms, including minority tax, medical students, and undergraduate medical education. We included publications if they discussed the underrepresented in medicine medical students’ experiences of the minority tax.
Results: Our search yielded six peer-reviewed original research articles and six publications of commentaries, opinion pieces, or news pieces. Students who were underrepresented in medicine reported spending more hours on diversity efforts compared with students who were not underrepresented; moreover, students reported that they had to sacrifice academic excellence in order to fulfill these additional diversity duties.
Conclusions: The minority tax among medical students constitutes an unequitable and unjust barrier to career advancement, and it likely represents an early cause of attrition in the pipeline of underrepresented in medicine academic faculty. Medical educators can enact specific recommendations to eliminate or mitigate the minority tax experience for medical students.

The effect of corruption on public debt sustainability: Evidence from the European Union’s countries
Authors: Alamro Hassan
Published: March 2024

Corruption has significant implications for economic development and stability. It distorts market mechanisms, undermines public trust, and hampers investment and economic growth. Understanding the impact of corruption on the economy helps policymakers design effective anti-corruption measures and promote good governance. The dearth of studies examining the influence of corruption on the relationship between public debt and economic growth is the research challenge that the study addresses. Numerous studies have investigated the association between economic growth and public debt, but few have explored the impact of corruption on these variables. Our research aims to fill this gap by examining the impact of corruption on the connection between economic growth and public debt. To achieve this, we employed a dynamic panel generalized method of moments models (Arelleno & Bover, 1995) and fixed effects models using data from 28 countries spanning from 2012 to 2019. The empirical results show that there is a statistically significant interaction term between debt sustainability and corruption. This supports the idea that the impact of public debt on economic growth is a function of corruption, with a negative sign for the marginal effect. Therefore, public debt hinders economic growth in corrupt nations.
The Art of Design: Seeing The Bigger Picture
Authors: Kathryn Jane Moore
Published: March 2024

Using words and images referencing nature and culture, this research investigates the process and impact of creating spatial visions for ‘seeing the bigger picture’ in order to inform the transformation of regions. The researcher’s work explores radical mapping as an analytical and artistic tool, which has led to the development of a sequence of case-studies, exhibitions, richly illustrated presentations, publications, new policies, mentoring, student collaboration and an infrastructure of stakeholder engagement. Across this powerful and varied range of outcomes the research has situated a new cohesive and integrated landscape-led approach which transforms the physical materiality, ideas, memories and visions of the future in order to shape the experience we have of place as the social, physical and cultural context of our lives.

This research crosses professional and disciplinary boundaries using artistic, landscape and geographical expertise to re-evaluate the assumptions underlying practice-based research inquiry and the relationship between landscape and philosophy. It represents a significant shifting of methodology, away from the dominant scientific/social science paradigm, towards an approach that is deliberately more ambiguous and interpretative. The methods require an understanding of perception as intelligence and define landscape as the relationship a community has with its territory. The research thus seeks to address whether ideas can transform a region, and if so, how?

The research has led to an extraordinary number of high-profile outcomes spanning academic and public arenas. This includes peer reviewed papers, numerous exhibitions and developmental publications. In addition, it has informed the policy and ‘landscape-architecture’ thinking used by HS2 in the development of its pioneering West Midlands National Park, which underpins the West Midlands Combined Authority’s current sustainability agenda; directed long-term socioeconomic and environmental regeneration in the Black Country; and informed a UNESCO International declaration. Details of the research and publications are in the Research Catalogue exposition.
Effect of ultrasonic vibration on microstructural evolution, clad defects, and surface properties in laser direct energy deposition of Inconel 625
Authors: Dash Biplab Kumar , Bhatnagar Shrey , Magham Hari Srinivasa Rao , Rao Shubham , Muvvala Gopinath , Mullick Suvradip
Published: March 2024

Laser direct energy deposition (DED) has some accompanying issues, such as existence of micropores, elemental segregation at grain boundaries, intergranular corrosion, etc. Therefore, the current work aims for a reduction in clad defects and enhancement in surface properties for laser direct deposition of Inconel 625 by implementing ultrasonic vibration. The acoustic streaming and cavitation effect induced by ultrasonic vibration results in the breaking of columnar grains, along with grain refinement and better elemental distribution in the matrix during the solidification process. The investigation is carried out for deposition using a 240 W Yb-fiber laser under the application of ultrasonic vibration with a variable amplitude of 6–13 μm (frequency: 33–28 kHz). A relatively higher vibration amplitude was found more efficient in converting long columnar grains into finer and uniformly distributed equiaxed grains, with a significant reduction in micropores. Further, it resulted in a shorter molten pool lifetime because of the generation of more nucleation centers, leading to better cooling. The above effects resulted in higher microhardness of the deposited layer. Further, the wear and corrosion resistance showed an improvement with the application of vibration, which may be due to the finer equiaxed grains, less porosity, and better elemental distribution at a higher vibration amplitude.
Ensuring Safe Working Conditions under the Influence of Vibroacoustic Factors on Train Crew Workers
Authors: Sokolov D. A. , Golovina E. I.
Published: March 2024

Introduction. The increased intensity of noise and vibration of railway traffic may become not only an urgent problem in the field of occupational safety, but also a serious environmental problem in the near future due to the constant need to increase the weight of freight trains, the speed of passenger trains and the capacity of railway lines. Recently, a lot has been done to minimize the negative effects of noise and vibration in railway transport. However, the problem of exceeding the indicators of vibration noise factors remains relevant. Reducing the harmful effects helps to improve the working conditions of train crew employees and improve the comfortable conditions of transport passengers. As a rule, the main focus of the analysis is on the external impact of vibroacoustic factors on residential areas and less attention is paid to the impact on rolling stock. However, these studies do not provide a complete picture of how noise and vibration actually affect the train in motion. The aim of the study was to obtain the result of an analysis of the impact of vibroacoustic factors on train crew workers and to propose a method of comprehensive protection based on the use of vibration damping materials.

Materials and Methods. In the course of the work, regulatory documents were studied, a comprehensive analysis of relevant information on this topic was carried out, and methods for calculating vibration and vibration acceleration were used. The values of the sound pressure levels were obtained using a SPM-101 sound level meter. The object of the study was a carriage of the "reserved seat" type in the process of movement. As part of the research plan, sound pressure was measured at selected sites and a class of working conditions was determined.

Results. The result of the analysis of the impact of vibroacoustic factors on train crew workers indicated the need to strengthen comprehensive measures to protect them. The obtained calculation of the vibration force became the basis of the method proposed by the authors to minimize the harmful effects of vibroacoustic factors, which was based on the use of vibration and sound insulation materials suitable for the necessary acoustic parameters in the construction of the car. In particular, it was proposed to cover the floor of the car with dense rubber and the ceiling of the car with an inorganic fiber material for sound insulation. The work also provides an economic assessment of the effectiveness of measures to minimize harmful vibration noise effects.

Discussion and Conclusion. The proposed methods for minimizing noise and vibration impacts can help reduce the level of sound pressure and vibration indicators to standard values, which will significantly reduce the negative impact of vibroacoustic factors on train crew workers and railway passengers. The considered complex for minimizing vibration and noise includes a set of methods in which affordable materials based on recycled substances have found application.
Content and Dispersion of Ferroalloys in the Coating During Microarc Alloying of Steel
Authors: Stepanov M. S. , Dombrovskii Yu. M.
Published: March 2024

Introduction. The main disadvantage of traditional processes of diffusion surface hardening of steel products is its long duration. Therefore, the problem of intensification of such processes is relevant. To solve it, the use of high-energy effects on the material is proposed, which allows us to obtain a hardened surface layer from a coating composed of ferroalloy powders containing alloying elements. There is no data in the literature on the required content and dispersion of such powders in the composition of the coating. The aim of this study was to select the particle size of ferroalloys and their concentration in the coating to achieve the most effective hardening of the processed product.

Materials and Methods. For experimental studies, cylindrical samples made of steel 20 with a diameter of 12 mm and a length of 35 mm were used. On the surface of these samples, an alloying coating containing ferroalloy powders and an electrically conductive gel as a binder was applied. After that, the samples were immersed vertically for half their length into a metal container, which was then filled with carbon powder with a particle size of 0.4–0.6 mm. Then an electric current of 2.5 to 3.0 A was passed in the circuit power source — container — carbon powder — sample. The duration of the process was 2–8 minutes.

Results. The calculated estimation of the electrical conductivity of coal powder was performed, and the thermophysical parameters of microarc heating of steel were calculated. These include the power released by electric current on the surface of the steel product, the density of the heat flux, and the energy of a single microarc discharge. The expressions for calculating the particle size of ferroalloy powder were obtained, as well as the experimental dependencies of the diffusion layer thickness on the particle size of ferroalloys and their content in the coating.

Discussion and Conclusion. The results of this study have allowed us to determine the size range of ferroalloys and their content in the coating. This information is essential for optimizing the alloying process and ensuring the most efficient surface hardening treatment for steel products. The data collected will be used to develop improved technological processes for the surface hardening process, leading to improved product quality and performance.

Reading literacy is a fundamental skill for everyone. This can be instilled from a young age. The Government of the Republic of Indonesia, through the Ministry of Education and Culture, issued Regulation Number 23 of 2015 on the Development of Student Characteristics. This policy forms the foundation for the School Literacy Movement program, which is intended to increase students' interest in reading and cultivate literacy. The purpose of this study is to analyze efforts to improve students' reading literacy culture at Madrasah Ibtidaiyah Dewi Masyithoh 02 Banyumudal Pemalang Indonesia through the School Literacy Movement program. The descriptive qualitative approach was used in this study. The study lasted from 18 October 2022 to 12 January 2023. Data was gathered through observation, interviews, and documentation. The data analysis technique includes three steps: data reduction, data display, and data verification. The findings revealed that several efforts were made in the classroom to improve students' reading literacy culture, including implementing a habituation program to read books before beginning learning, reading asma'ul husna, reading salawat, memorizing juz amma, providing reading corners, posterization, and procuring existing literacy trees. The literacy program was introduced in two stages. The first stage was carried out by reading asma'ul husna and salawat in the school yard, and the second stage was carried out by reading juz amma and developing reading habits before learning began. The impact of implementing the program is that students become accustomed to reading. The reading literacy program should be integrated into other school-based and community-based programs.

Published: March 2024

OBJECTIVE

To assess the characteristics of blebs formed after Ahmed glaucoma valve (AGV) surgery in dogs using ultrasound biomicroscopy (UBM) and to analyze their correlation with postoperative intraocular pressure (IOP).

ANIMALS

16 eyes (13 dogs) were diagnosed with primary angle-closure glaucoma and were followed up after AGV surgery from June 2021 to September 2023.

METHODS

In this prospective study, UBM examinations were performed to assess bleb characteristics, including bleb wall thickness and reflectivity. IOP at the time of UBM imaging and the duration from AGV surgery to UBM imaging were recorded. Histological examination of an enucleated eye removed due to uncontrolled IOP leading to blindness was also conducted.

RESULTS

A significant correlation was observed between IOP and relative reflectivity (Pearson r = 0.60; P = .01), and a negative correlation was observed between bleb wall thickness and relative reflectivity (Pearson r = −0.72; P = .002). No significant correlation was observed between the duration from AGV surgery to UBM imaging and either bleb wall thickness or relative reflectivity, respectively. Histological examination of the enucleated eye revealed collagen-rich fibrous encapsulation of the bleb wall, including myofibroblasts that exhibited positive α-smooth muscle actin immunostaining.

CLINICAL RELEVANCE

In dogs that underwent AGV surgery, less dense, thick-walled blebs on UBM tended to maintain IOP within the normal range. However, denser, thinner-walled blebs showed IOP levels above the normal range despite the use of antiglaucoma medications. UBM is a useful tool for evaluating bleb characteristics and their influence on IOP regulation after AGV surgery in dogs.

Published: March 2024

The present study aimed to determinate the effect of external progesterone (P4) supplementation on luteolysis in cows under heat stress. Forty-eight (n=48) dairy cows in the period from July–September 2018 were part of and at day 35±3 postpartum scored for BSC, synchronized using PG-3-G + Ovsynch protocol and randomly allocated into two treatments: PRID group (n=27) treated with external P4 device between G1 and PGF2α and CON group (n=21) left without treatment. Collection of blood samples to assess P4 concentrations was done at Pre-PG, at G1, at PGF2α, at 72 h after PGF2α (at timed artificial insemination TAI) and at d 21 after TAI. The pregnancy diagnosis was done at d 21 and d 30 after TAI by ultrasound. The average temperature-humidity index (THI) was 79.5±0.6. At G1, the P4 was significantly lower in the PRID group (1.84±0.99 ng/mL) in comparison to the CON group (2.97±1.82 ng/mL). In contrast, at PGF2α, there was a tendency (p=0.09) of increased P4 concentration in PRID group compared with the CON group (4.26±1.68 and 3.74±2.39 ng/mL), respectively. At TAI, more PRID cows (p=0.0001) had a lower P4 (0.06±0.03 ng/mL), in comparison to CON (1.28±2.41 ng/mL). At d 21 and d 30 after TAI, more PRID cows were predicted and diagnosed pregnant (16/27 or 59.25% and 13/27 or 48.14%) compared with the CON group (11/21 or 52.38% and 8/21 or 38.08%) respectively, but without any significant differences. Supplementation of the P4 during the Ovsynch protocol increases the P4 before TAI and reduces the incomplete luteolysis in heat stressed dairy cows.

Published: March 2024

Hyperadrenocorticism (HAC) in dogs is routinely treated with trilostane single-dose (CTG) which is reported to cause adverse reactions. The current retrospective study of several dogs with terminal stage of HAC aimed to compare the clinical, hematological, and biochemical effects of trilostane titration-dose treatment (TTG) with the single-dose treatment (CTG). All clinical cases (n=7) were confirmed on HAC by anamnestic, clinical, hematology, biochemistry, and low-dose dexamethasone suppression test findings, indicative for Cushing’s disease. Two cases were treated with CTG (2.2-6.7 mg/kg, single dose daily) and their treatment was discontinued on the second week due to adverse reactions. The TTG cases were treated for up to 12 weeks (0.5 mg/kg once daily for 7 days, and then with 0.5 mg/kg twice daily for 7 days). Blood samples and clinical checks were performed on 0., 4., and 12. weeks of the treatment. Hemoglobin was non-significantly higher in TTG at 12 weeks. Alanine transaminase was significantly lower in the TTG cases on the 12. week of the treatment (78.04±15.37 U/L) compared to the 0-week (137.81±24.03 U/L), and 4-week samples (131.92±23.36 U/L). No significant differences were observed with the CTG cases. Alkaline phosphatase was significantly lower on 12-week samples in TTG (251.02±93.06) compared to the 4-week (567.94±283.93 U/L), and 0-week samples (1,341.84 U/L). In conclusion, TTG has indicated to have significantly higher tendency to decrease alanine transaminase and alkaline phosphatase, alleviating the negative effects on the liver. The clinical findings were more adverse for the CTG.

El presente trabajo, como estudio de caso, expone problemáticas situadas de carácter hídrico en la localidad Kilómetro 30, ubicada en la zona rural del municipio de Acapulco, Guerrero, México. Más que pretender proponer soluciones a partir de agendas ambientales estandarizadas internacionales, este documento resalta las relaciones de poder y formas de gobierno que emergen ante escenarios críticos de abastecimiento de agua, así como la asimetría en la gobernanza de dicho recurso. Se tiene como objetivo analizar las prácticas de gestión de agua para uso doméstico bajo la óptica de un enfoque sociocultural de las relaciones sociedad-Estado Para ello, se emplea metodología cualitativa, que involucra al mismo tiempo observaciones de tipo etnográfico y entrevistas a profundidad que siguen el modelo de mapeo de actores involucrados en políticas ambientales: actores institucionalizados estatales, institucionalizados no estatales y no institucionalizados. Se concluye que las prácticas como acciones, discursos, reglas y recursos que se ponen en juego en el marco de relaciones históricas de violencia política y social se encuentran en el punto marginal entre lo legal y lo ilegal, moviéndose libremente entre ambas dimensiones mientras esto permita la sobrevivencia en condiciones socioambientales hostiles.

En este estudio de contraste se proponen las FDP beta-kappa y beta-Pareto, y se consideraron FDP de uso generalizado las tres siguientes: la Log-Pearson tipo III, la general de valores extremos y la logística generalizada. Por lo anterior, se expone para las dos primeras FDP un resumen de su teoría y su método de ajuste por máxima verosimilitud. Se procesan 11 registros de datos hidrológicos extremos anuales y se contrastan los ajustes con dos índices: el error estándar de ajuste y el error absoluto medio. La selección de las predicciones en los siete periodos de retorno (Tr) estudiados se basó en los valores menores de los errores de ajuste y en la búsqueda de predicciones representativas, en los Tr ≥ 500 años. Las conclusiones sugieren la inclusión de las distribuciones beta-kappa y beta-Pareto en los análisis de frecuencias debido a su versatilidad y facilidad de ajuste.

Objective: The research aims to determine the leadership style found in villages in the Lake Toba area which have natural, biological and cultural potential, where presumably, the head of the village head will be able to make breakthroughs in developing the village into a tourist village. The tourism development target for Lake Toba is 1,000,000 foreign tourist visits in 2019, and the damage to tourism infrastructure due to the 2020-2022 pandemic out-break makes this target even more difficult to achieve.
 
Theoretical framework: Qualitative research conducted using the phenomenological approach. Research validity was obtained through triangulation of data sources and reliability was carried out through repeated observations a year later.
 
Method: Of the 30 villages located on the shores of the lake, 15 villages were selected for observation and interviews, afterward reduced to 10 villages using feature and demographic approaches. This research is increasingly necessary considering that the world tourism trend is towards the environment, and the development of villages into tourist area can be achieved if the village head's leadership style is appropriate.
 
Result and conclusion: The research proves the similarity of village heads' experiences in leading villages, integratedly, in a bureaucratic, democratic and transformative manner, where these actions can create change and increase the welfare of village residents. The village head who supports the development of National Tourism Strategy Area of Lake Toba leads holistically.
 
Research implications: The research provides the government with a standard leadership model that the village head can use to oversee the hamlet's transition into a tourism destination and obtain accreditation.
 
Originality/value: The research found a leadership model, namely leadership based on statutory regulations, local wisdom and transformation, which was classified then as bureaucratic, democratic and transformative leadership models.
Unraveling the Nexus: A Bibliometric Analysis of Subjective Wellbeing, Individualism-Collectivism and Sustainable Consumption Research in The Last Decade
Authors: Zimmermann Cristiane Soethe , De Quadros Cynhtia Boos , De Souza Júlio Cesar Lopes
Published: March 2024

Purpose: This paper intends to contribute to the academic field by pointing out trends in studies on subjective wellbeing and exploring the possibility of new interconnections with different constructs, especially in a scenario of significant changes in consumption behavior, such as the post-pandemic one. In the managerial area, it aims to collaborate by providing relevant information on the effects of sustainable consumption on subjective wellbeing, particularly for marketing professionals and the development of marketing strategies.
 
Method:  The study conducts descriptive and bibliometric analyses of the 236 selected articles found in the literature over the last ten years, establishing connections between the main theories. 
 
Results  and  conclusion: Although the studies found do not directly associate the three main constructs that are the focus of the research, there is a clear relationship between them. Studies show individualistic or collectivistic orientation as an antecedent of sustainable consumption; the influence of culture on the level of subjective wellbeing; as well as a positive relationship between sustainable consumption habits and subjective wellbeing and an inversely proportional relationship between individualism and sustainable consumption.
 
Research implications: We can understand as relevant that future studies on sustainable consumption should take into account individualism-collectivism and wellbeing, seeking a comprehensive and systematic approach to sustainable consumption, considering the role of individual citizens in society, and exploring the link between the provision of sustainable products and diverse sustainable consumption practices. It is necessary to consider the complex and multifaceted nature of wellbeing, as well as the cultural and societal factors that influence it, and take a holistic approach that considers the interplay between individual, community, and social wellbeing.
 
Originality/value: The study contributes to the integration of constructs, since the article seeks to fill a gap by exploring the interconnection between three main constructs - subjective wellbeing, individualism/collectivism and sustainable consumption. In doing so, it provides an integrated view that can enrich theoretical discussions in these areas. In addition, the bibliometric analysis reveals recent trends in the literature, highlighting the areas that have received the most attention and those that are less explored. This information can guide researchers for future studies and explore knowledge gaps. By considering the influence of culture on the relationships between the constructs, the article also contributes to a deeper understanding of how cultural differences can shape perceptions of wellbeing and sustainable consumption practices.
Optic neuritis: a review of diagnostic imaging modalities and effective management approaches

Optic neuritis (ON) is a medical condition characterized by an acute inflammation of the optic nerve, usually caused by multiple sclerosis (MS). However, there are other causes such as infectious diseases, granulomatous disease, paraneoplastic disorders, and demyelination disorders. Usually, the commonest presentation is unilateral painful loss of vision. This study aimed to review the diagnostic imaging modalities and effective management approaches of ON. ON can be diagnosed through different modalities such as magnetic resonance imaging, which is the modality of choice to assess ON, providing crucial insights into the structural and functional changes within the optic nerve. In ON, the retrobulbar intra-orbital segment of the optic nerve often exhibits noticeable characteristics, including swelling and a high T2 signal. In addition, optical coherence tomography is a new, noninvasive tool for direct visualization of the head of the optic nerve that can detect thinner retinal nerve fiber layers diagnosing ON. In treating ON and MS, the main aim is to reduce the recurrence and severity of the attacks to minimize the subsequent disability. The utilization of disease-modifying drugs contributes to delaying the onset of subsequent episodes, reducing the occurrence of MS relapses, and minimizing the formation of demyelinating lesions.

Published: March 2024

Objective: This study aimed to investigate the impact of intraoperative anesthesia care handovers on mortality, hospital readmission, and intraoperative/postoperative complications in patients undergoing major surgery in Saudi Arabia.
Methods: It was a retrospective cohort study conducted in Riyadh, Saudi Arabia. An Excel sheet was used for data entry. A convenient sampling method was used in the study.
Results: The majority of the patients were female (53.7%) and aged between 21 and 60 years (71.5%). Overweight and obese individuals accounted for a significant proportion of the sample. Anesthesia handover was performed for a small percentage of patients (11.3%). Postoperative pain was reported by 37.5% of patients, while nausea and vomiting were experienced by a smaller percentage. The use of pain medications was relatively low (22.2%), with morphine being the most common choice. Vital parameters such as heart rate and blood pressure showed significant changes after the procedure. Anesthesia handover was associated with higher rates of postoperative pain and had a significant correlation with postoperative nausea and vomiting.
Conclusion: The findings of this study contributed to improving perioperative care and optimizing patient outcomes in the field of anesthesia. The study highlighted the importance of tailored pain management strategies and standardized protocols for anesthesia handover. Further research is needed to refine perioperative practices and enhance overall patient care.

Objective: The present study aimed to evaluate the prevalence of headache among a selected group of pregnant women residing in the Central region of Saudi Arabia.
Methods: A cross-sectional study was conducted between January and December' 2023 targeting pregnant women who were receiving prenatal care at Primary Healthcare Centers located in the Central region of Saudi Arabia. A sample size of 400 pregnant women was found appropriate employing a convenience sampling technique. The data were gathered by administering a systematic questionnaire that encompassed inquiries regarding demographic attributes, obstetric background, and the kind of headaches.
Results: The current study included 400 pregnant women with mean age of 28.7 years (SD = 4.1). Among the participants, prevalence of headache during pregnancy was 39.5% (n = 158). The odds of experiencing headache during pregnancy were higher among older women [adjusted odds ratios (aOR) = 1.11, 95% confidence interval (CI) = 1.03-1.19], women with lower educational levels (aOR = 1.97, 95% CI = 1.10-3.52), women with a history of headache before pregnancy (aOR = 2.54, 95% CI = 1.60-4.05), women with two or more previous pregnancies (aOR = 2.12, 95% CI = 1.23-3.64), and women in the second trimester of pregnancy (aOR = 2.05, 95% CI = 1.21-3.47).
Conclusion: Headaches are an often-experienced issue among pregnant women, which negatively impacts their overall well-being and ability to do daily activities.

Authors: Ali Nidhal Faisal , Al-Husseiny Hassan F.
Published: March 2024

A general treatment function with an epidemic model that involves the delay in the treatment period has been  proposed and studied in this work. This model contains two compartments, namely susceptible denoted by and infected denoted by . The existence of all the fixed points has been determined. The system has two equilibrium points, namely the uninfected equilibrium point (UIEP) and the endemic equilibrium point (EEP). The conditions for local stability and Hopf bifurcation have been discussed. The stability of the periodic solutions and  the direction of the Hopf bifurcation properties have been studied analytically and numerically.
