Authors: Sinaga Joshua Princeman , Sinaga Bintang Yinke Magdalena , Siagian Parluhutan , Eyanoer Putri Chairani , Samodra Yoseph Leonardo
Published: December 2024

Background:Post-COVID Syndrome (PCS) is a newly recognized condition reported by approximately 45% of individuals following COVID-19 infection. This syndrome is estimated to affect the health-related quality of life in 10–30% of affected individuals.
Objective:To examine the characteristics of Post-COVID Syndrome among healthcare workers at Adam Malik Hospital.
Methods:This study employed a cross-sectional descriptive design. Data were collected using structured questionnaires administered to healthcare workers at Adam Malik Hospital who had contracted COVID-19 between 2020 and 2022.
Results:A total of 120 participants were included in the study. The sample was predominantly female (78.3%), with the youngest age group (19–30 years) comprising 37.5% of participants. Most participants had direct exposure to patient care (78.3%) and were confirmed COVID-19 positive in 2021 (42.5%). Notably, 45.0% of participants were unvaccinated, 20.9% had a history of hospitalization, and 78.3% experienced mild COVID-19 infections. Hypertension was identified as the most common comorbidity. Participants were categorized as experiencing Acute PCS (43.9%) or Chronic PCS (56.1%), with both groups exhibiting similar predominant symptoms, including fatigue, persistent cough, memory impairment, and cognitive difficulties. Statistically significant associations were identified between PCS and variables such as sex (p=0.004, OR=0.27), age (p=0.015, OR=4.46), severity of prior COVID-19 infection (p=0.040, OR=1.77), vaccination status (p<0.001, OR=3.82), and the presence of comorbidities (p=0.025, OR=2.53).
Conclusion:Post-COVID Syndrome is characterized by multifactorial etiologies and heterogeneous clinical manifestations. Factors such as gender, age, vaccination status, comorbid conditions, and severity of prior infections were significantly associated with PCS outcomes. Gender-related differences, potentially influenced by immune response, hormonal mechanisms, and antibody production, appear to contribute to variations in PCS manifestations. These findings underscore the need for further research to elucidate the epidemiology, clinical presentations, and pathological mechanisms underlying this emerging post-viral condition.

Authors: Panjarut Laisuwannachart , Chamroonsawasdi Kanittha , Vatanasomboon Paranee , Kittipichai Wirin
Published: December 2024

Background: Adolescent pregnancy is an important global health concern. Almost 21 million adolescent women between the ages of 15 and 19 in developing countries become pregnant, and approximately 12 million of them give birth annually. Adolescent pregnancy has consequences for the health, social, and economic outcomes of adolescent women, their babies, and their families. Those in rural areas are particularly vulnerable due to poverty, inadequate education, limited access to contraception, and traditional beliefs.

Objective:This qualitative study aims to explore the root causes of adolescent pregnancy in rural Thailand.

Methods: This qualitative study was conducted from August to September 2023. We collected data through in-depth interviews with three mother-daughter dyads, whose daughters experienced adolescent pregnancy, and focus group discussions among four healthcare providers and four school teachers. We transcribed the data verbatim and applied thematic analysis.
Results: The findings showed that the root causes of adolescent pregnancy include: 1) inadequate problem-solving skills to prevent adolescent pregnancy; 2) ineffective sexual communication; 3) poor family relationships; and 4) poor behavior control to prevent adolescent pregnancy.

Conclusion:Our findings reveal the root causes of adolescent pregnancy in rural Thailand. Understanding these factors allows us to better address the unique challenges faced by adolescents in these communities. We should focus on these factors to design tailored interventions and involve multilevel stakeholders, including family, school, and healthcare services to prevent adolescent pregnancy.

Authors: Damayanti Ratih , Lutfiya Indah Lutfiya , Noviarmi Fadilatus Sukma Ika Noviarmi
Published: December 2024

Background:The manufacturing industry is a sector that transforms raw materials into finished goods. Nutritional status plays a critical role in determining a worker's productivity, with poor nutritional status often associated with reduced efficiency.
Objective:This study aimed to analyze the relationship between various factors and the nutritional status of workers in the manufacturing sector in Surabaya, Indonesia.
Methods:This analytical observational study utilized a cross-sectional design. Data collection was conducted from January to March 2023 among manufacturing workers at PT A in Surabaya, East Java Province, Indonesia. Of the total 500 workers, 370 respondents were selected as the study sample. Independent variables included gender, marital status, education level, smoking habits, number of children, exercise habits, contraceptive method usage, and workload level. The dependent variable was nutritional status. Statistical analysis was performed using the Spearman correlation test and the contingency coefficient correlation test to evaluate the relationships between variables.
Results:The majority of workers at PT A were male, had a high school education, were married, had 1–2 children, did not use contraceptive methods, were non-smokers, exercised infrequently, and had a moderate physical workload. Significant associations were found between nutritional status and variables such as gender, marital status, contraceptive method usage, smoking habits, and workload level. However, no significant relationships were observed between nutritional status and educational background or the number of children.
Conclusion:Among the factors examined, workload level demonstrated the strongest association with nutritional status, likely due to its direct impact on the physical activity required during job tasks. This finding highlights the importance of considering workload in strategies aimed at improving workers' nutritional health.

Authors: Edris Hussen , SREEMANARAYANA V.
Published: December 2024

Background:Hepatitis B kills a large number of individuals every year all over the world. Despite the critical nature of this issue, the extent of hepatitis B virus infection among pregnant women in the Afar Region remains unknown. Therefore, this study aimed to assess the Prevalence of the Hepatitis B Virus and its associated factors among pregnant women Attending Antenatal Care in Public Hospitals in Afar, Ethiopia.
Method:A hospital-based cross-sectional study was conducted from August 1, 2023, to August 2, 2024, involving 442 pregnant women attending antenatal care at five public hospitals in the Afar Region. Structured and pretested questionnaires were used to collect socio-demographic data and associated factors. Blood samples were collected from each consenting participant after the interviews to assess their HBV status. The data was analyzed using SPSS, applying bivariate and multivariable logistic regression methods to identify associations and determine statistical significance, with a p-value threshold of less than 0.05.
Result:The overall Prevalence of hepatitis B virus infection was 12.7% (95% CI: 9.7-16.1). Hepatitis B virus infection had a significant association with a family history of the virus (AOR=3.92; 95% CI [1.26-12.14]), sharing sharp objects (AOR=3.83; 95% CI [1.16-12.6]), female genital mutilation (AOR=4.77; 95% CI [1.02-22.3]), extraction of teeth (AOR=5.22; 95% CI [2.54-10.7]), and hospital admissions (AOR=2.48; 95% CI [1.15-5.35]).
Conclusion:This study revealed a high prevalence of HBV in specific public hospitals in Ethiopia's Afar regional state. The study found that a history of Hepatitis B virus in the family, sharing of sharp objects, having teeth extraction, hospital admission, and female genital mutilation are important risk factors that lead to the high viral Prevalence in the Afar Region. Establishing comprehensive prenatal screening programs, educating the public, and considering cultural considerations are essential to solving this public health issue.

Authors:   Economic Research Institute, Kurnosova Olesya A. , Timashkova Olga A. ,   Economic Research Institute
Published: December 2024

An algorithm for making decisions on improving business processes of industrial enterprises in the context of digital transformation has been developed. Unlike existing ones, the proposed approach includes: analysis of the impact of business process change indicators on the dynamics of the financial result in order to determine the direction of such impact and identify reserves for financial result growth; construction of business process change maps; forecasting the development of industrial enterprises under the influence of change, improvement and modification of their business processes. To analyze the impact of business process change indicators on the dynamics of the financial result, it is proposed to use multifactor deterministic analysis. Business process change maps are the author’s development, representing a graphical method for selecting tools for changing, improving and optimizing business processes. Scenario forecasting of the development of industrial enterprises taking into account the impact of business process change indicators makes it possible to ensure the validity of decisions made on the choice of development strategy in the context of digital transformation. The application of the proposed algorithm in management practice will provide the decision-making process with effective methodological and analytical tools and will contribute to increasing the digital maturity of industrial enterprises.

Once numbering in the tens of millions, plains bison (Bison bison bison) were nearly driven to extinction with only a few hundred individuals remaining by the late 19th century. Plains bison have since recovered to approximately 20,000 animals managed in conservation herds throughout North America, yet substantial challenges to their recovery remain.

The Department of the Interior (DOI) is working with diverse partners to steward approximately 11,000 bison in 18 conservation herds across 12 states. Most herds exist in areas without native predators, and removals are required to keep herd sizes at or below carrying capacity. The loss of genetic diversity within bison, and the fact that most DOI herds are relatively small and isolated from each other with no opportunity for natural gene flow, raises concerns about maintaining genetic diversity over the long term. Connecting populations through gene flow (i.e., creating a metapopulation) can minimize loss of genetic diversity, both within and across populations.

Management of DOI bison conservation herds has historically varied across bureaus and conservation units. Adopting a national perspective on bison conservation was identified as a priority in the 2008 Department of the Interior Bison Conservation Initiative (BCI). The concept of metapopulation management as a potential tool to maximize the conservation of genetic diversity among DOI herds was first described in this 2008 Initiative and was specifically encouraged in the 2010 DOI Bison Conservation Genetics Workshop report (Dratch and Gogan 2010). In the 2020 BCI, the DOI re-affirmed its commitment to conserving bison as native, North American wildlife.

This document establishes a framework for a nationally coordinated strategy for bison managed by the DOI to support the genetic conservation goals outlined in the 2020 BCI. This is a decision-making framework that guides managers through the process of determining when and how to consider translocations. Decisions and actions within the framework are informed by analysis and interpretation of data housed in an integrated, relational database that will be initially populated with the most current data and updated annually thereafter. It provides science-based guidance on how to conserve DOI bison genetic diversity through strategic translocations, while also considering cattle introgression and bison health. We illustrate how this Strategy can be used to guide the establishment of new conservation herds and discuss what it means to be a DOI partner. Finally, this is intended to be used as a living document that will evolve as needs and technologies change.

The gas station often faces long queues that cause inconvenience and decrease operational efficiency. The research method includes collecting primary data through direct observation to obtain information on the number of vehicle arrivals, service time, and the number of operating booths. Secondary data is obtained from the literature related to queuing systems. After the data is collected, distribution analysis is conducted to understand the arrival and service patterns. A simulation model is created and tested using Arena Software. Model verification and validation ensure the accuracy of the simulation results. The research findings show that in the initial model, 54 vehicles were served in 50 minutes with an average waiting time of 45.9506 seconds. The first improvement scenario added one operator to each server, while the second scenario added a new server with two operators. The second scenario provided the best results with 106 vehicles served in 50 minutes and the waiting time reduced to 31.6773 seconds, showing a significant increase in system efficiency. The percentage increase in the number of vehicles served is approximately 96.30%, while the waiting time decreased by 31.06%. The implementation of the second scenario is expected to reduce queues and improve customer satisfaction and operational efficiency at the gas station.
