Authors: Aan Johan Wahyudi
Published: January 2025

Biogeokimia adalah cabang ilmu yang mempelajari transfer material dari atmosfer, hidrosfer, litosfer, dan biosfer. Penelitian biogeokimia laut, terutama terkait dengan perubahan iklim, pengasaman laut, dan pemanasan global, meningkat sejak awal 1990-an. Di Asia Tenggara, penelitian ini lebih berfokus pada dampak aktivitas manusia. Perkembangan peralatan analisis modern telah mempercepat pemahaman tentang siklus karbon, memungkinkan kuantifikasi karbon dan identifikasi peran organisme dalam transfer karbon. Penelitian tentang dekomposisi material organik dan peran vegetasi laut dalam menyerap karbon dioksida telah berkembang dengan teori dan pemodelan terbaru. Perkembangan teknologi analitik dan komputasi juga telah mempermudah pengumpulan dan analisis data dalam penelitian biogeokimia karbon. Teknik pemetaan spasial menggunakan citra satelit dan sensor penginderaan jauh memungkinkan pemantauan perubahan lahan dan vegetasi laut secara akurat. Selain itu, kemajuan dalam pemodelan komputer memungkinkan simulasi interaksi kompleks antara faktor biologis, kimia, dan fisik yang mempengaruhi distribusi dan perubahan karbon.
Peningkatan karbon antropogenik di atmosfer sejak revolusi industri telah mengubah kondisi bumi dan biosfer, termasuk variabilitas karbon laut yang mempengaruhi produktivitas laut. Selain itu, variabilitas iklim di Indonesia, hasil dari dinamika laut dan atmosfer, mempengaruhi variabilitas biogeokimia karbon laut. Selama ini laut Indonesia berperan penting dalam siklus karbon laut global karena keanekaragaman ekosistem, pola sirkulasi laut, dan lokasi geografisnya yang strategis. Siklus biogeokimia karbon laut di Indonesia mencerminkan sifat dinamis dan berdampak global pada sistem biosfer.
Indonesia dengan karakteristik tropisnya memiliki berbagai jenis ekosistem yang menyediakan keragaman reservoar karbon, menghasilkan transfer karbon yang lebih kompleks dibanding wilayah subtropis. Informasi terkait siklus biogeokimia karbon laut Indonesia penting untuk kebijakan pembangunan nasional. Naskah orasi ini mengulas lima hal utama: siklus biogeokimia karbon laut, transfer biogeokimia karbon laut, variabilitas karbon laut Indonesia oleh sebab faktor eksogen, prakiraan deret waktu variabilitas karbon laut, dan relevansi riset terhadap pembangunan ekonomi biru. Bab-bab ini memberikan pemahaman mendalam tentang peran riset dalam pengelolaan lingkungan dan ekonomi berkelanjutan.

Authors: Ahmad Sofyan
Published: January 2025

Sektor peternakan memiliki kontribusi besar dalam pemenuhan kecukupan pangan dan gizi nasional, tetapi sebagian masih bergantung pada impor, khususnya komoditas daging dan susu. Diperlukan upaya untuk meningkatkan produksi daging sapi dan susu melalui peningkatan populasi dan produktivitasnya, salah satunya optimalisasi penggunaan pakan dengan imbuhan pakan (feed additive). Penggunaan imbuhan jenis antibiotic growth promoters (AGPs) telah dilarang di Indonesia sejak Januari 2018 karena adanya potensi resistensi mikroba patogen pada manusia. Sebagai alternatif, penggunaan imbuhan pakan alami non-AGPs dapat mengoptimalkan proses digesti pakan, produktivitas, dan kualitas hasil ternak serta mendukung kelestarian lingkungan.
Pengembangan riset imbuhan pakan berbasis mikroba dan bioaktif tanaman berpengaruh positif pada kecernaan bahan pakan dan produktivitas ternak, memiliki efek fungsional dalam meningkatkan kualitas produk daging, telur, dan susu, serta berimplikasi pada peningkatan nilai ekonomi budi daya ternak. Tahapan awal inovasi ialah melalui isolasi dan identifikasi. Pemanfaatan isolat mikroba dari ternak inangnya atau dari ekosistem spesifik ditujukan agar kandidat mikroba memiliki kemampuan adaptasi dan sifat fungsional yang mendukung kinerja ternak. Inovasi imbuhan pakan berbasis tanaman dikembangkan dengan memformulasikan bioaktif tanaman, seperti daun mengkudu dan kenikir yang memiliki aktivitas antimikroba, antiparasit, dan antimetanogen. Aplikasi imbuhan pakan mikroba Pedioccoccus. acidilactici yang dikombinasikan dengan mineral organik mampu meningkatkan performa dan kualitas daging ternak ruminansia. Imbuhan pakan berbasis tanaman dari ekstrak daun mengkudu dan kenikir juga dapat menurunkan prevalensi penyakit koksidiosis pada unggas. Imbuhan pakan alami ini mendukung upaya peningkatan produktivitas ternak tropis melalui pemanfaatan potensi biodiversitas Nusantara guna tercukupinya pangan hewani yang begizi dalam menyongsong Indonesia sebagai Lumbung Pangan Dunia 2045.

This study aimed to evaluate the incubation of tambaqui eggs as an ecological indicator in natural nurseries, exposed to pesticides and as an indicator of water quality. Female and male tambaqui were induced. After fertilization, the eggs were separated for three trials: (i) incubation of eggs in water from urban and natural environments, (ii) incubation in different concentrations of glyphosate, malathion, and kasugamycin, considered pesticides, and (iii) with exposure of incubated eggs to different concentrations of total ammonia. In all trials, the design was completely randomized, with five replicates. (i) Analysis of variance indicated that the hatching rate was higher in the water of the Solimões River, and the lowest were in the Igarapé do Paraíba and Igarapé do Buriti streams (p<0.05), considered polluted. (ii) Treatment with incubation water containing 0.0 mg L -1 of glyphosate, malathion and kasugamycin showed the best fertilization, hatching and survival rates (p<0.05). (iii) Fertilization rate and hatching rate of tambaqui eggs were higher (p<0.05) in water containing between 0.0 and 3.5 mg L -1 of total ammonia. Larval survival was higher (p<0.05) in water containing concentrations between 0.0 and 2.0 mg L -1 of total ammonia. The results indicated that the best natural water for incubation of eggs is from the Solimões River. It was found that all agricultural pesticides presented toxicity in the incubation phase of tambaqui eggs. Finally, concentrations of up to 2.0 mg L -1 of total ammonia did not present implications on tambaqui eggs.

Authors: Gomes Jean Lopes , Sabino Fernanda Coutinho , dos Santos Samuel Oliveira , Nogueira Valéria Cristina
Published: January 2025

A população mundial passou por um dos momentos mais críticos da pandemia de COVID-19, causada pelo Coronavírus (SARS-CoV-2), que teve início em Wuhan, na China, no final de 2019. Os efeitos devastadores foram sentidos em diversas áreas, especialmente na economia e no mercado de trabalho. A crise gerada resultou em significativa redução de empregos, impactando de forma acentuada grupos socialmente vulneráveis, como as pessoas com deficiência. Essas pessoas enfrentam impedimentos de longo prazo de natureza física, mental, intelectual ou sensorial, que, em interação com barreiras diversas, podem dificultar sua participação plena e efetiva na sociedade, em igualdade de condições com as demais. Para mitigar essas desigualdades, foram criadas legislações como a Lei sobre Plano de Benefícios da Previdência Social, que obriga empresas a reservarem um percentual de vagas para pessoas com deficiência, proporcional ao número total de empregados. Durante o primeiro ano da pandemia, o mercado de trabalho enfrentou crises severas. Entre o primeiro e o segundo trimestre de 2020, registrou-se uma redução de 7,3 milhões de empregos, sendo 4,3 milhões de ocupações informais e 3 milhões de empregos formais com contribuições ao INSS. Essa situação agravou a exclusão de pessoas com deficiência do mercado de trabalho, dada sua maior dependência da Lei sobre Plano de Benefícios para obterem oportunidades formais. Mesmo em um contexto pós-pandêmico, o desafio da inclusão permanece. A alta informalidade e a falta de ajustes na legislação reforçam a exclusão desse grupo. Portanto, é urgente uma revisão e fortalecimento dessa Lei, garantindo mecanismos mais eficazes para a inserção e permanência de pessoas com deficiência no mercado de trabalho, promovendo assim uma sociedade mais inclusiva e igualitária.

Published: January 2025

Electrocoagulation is a technique that uses electric current to induce oxidation-reduction reactions, forming hydroxides that act as coagulating agents for the removal of emerging contaminants. The general objective of this study is to evaluate the efficiency of the electrocoagulation process applied to the treatment of emerging contaminant acetylsalicylic acid by electrocoagulation. Emerging pollutants are chemicals, both natural and synthetic, and can be organic and inorganic, with high toxic potential and negative impacts on both the environment and human health. A factorial design of 33 times in triplicate was developed, the important variables were reaction time and electrical voltage. The dependent variables or response were concentration and operating cost. At the end of the treatments, the results indicated that the highest percentage of acetylsalicylic acid elimination at 5 volts was 58.67% in the total times of 10, 20 and 30 minutes at the initial concentration of 0.3 mg/mL. In the 11-volt tests, the best removal efficiency was 60.00%, with 30 minutes of removal time. As expected, the greatest wear of the electrodes was obtained through the tests subjected to 11 volts, and in relation to the cost of operation, the test with the highest cost was R$ 3.15/m3. For tests subjected to 5 Volts, the highest cost was R$ 0.73/m3. The results of the study indicated significant elimination of aspirin. Therefore, this study can be a reference for other researchers or manufacturers to evaluate and estimate the process on a larger scale using this system for the treatment of synthetic wastewater.
PERCEPTION OF ACCEPTANCE OF TAX EVASION BY MANAGERS OF MICRO AND SMALL BUSINESSES IN VITÓRIA/ES
Authors: Lopes Sinara Silva Pinheiro
Published: January 2025

The purpose of this study was to address the main reasons why micro and small businesses choose to evade their taxes. Aiming at their own well-being in terms of tax obligations, these companies use illicit means and loopholes in the law to obtain favorable results on their taxes. Due to the constant search for tax reduction, municipal, state and federal agencies have adopted methods that provide monitoring in the fulfillment of obligations. These methods became possible due to the tools that store data in the database of the responsible agencies, data that refers to the operations carried out by the company, mainly information about the value of its revenue. Through the tool used by these inspection agencies, it became possible to carry out the control and analysis of the data transmitted to these agencies. Therefore, this study aims to identify and highlight the results of a survey published on an online platform on the main factors that motivate managers of companies established in the state of Espírito Santo, in the municipality of Vitória, to use fraudulent attitudes to avoid complying with their tax and fiscal obligations. It identified the profile of companies and managers, and that many managers accept using illegal methods to obtain even greater reductions in their taxes, even knowing that this act may have future consequences.

Authors: Cravo Giullia Lorena da Silva Busch , dos Santos Gabriel Calezani , Piccolo Maria da Penha , Maradini Filho Antonio Manoel
Published: January 2025

Chickpeas are a legume of the Fabaceae family, a source of proteins, lipids and carbohydrates, mainly long-chain ones such as oligosaccharides and polysaccharides. Chickpea flour is considered nutritionally superior compared to refined wheat flour, proving to be an abundant source of proteins. The use of mixed flours aims to partially replace wheat flour, aiming to improve the nutritional quality of food products and to meet the consumer's need for diversified products. The cookies were prepared by mixing chickpea flour with wheat flour, in proportions of 0%, 10%, 20%, 30% and 40% and other ingredients. Chickpea flour presented high levels of proteins, lipids and fibers, suggesting a high nutritional profile. Sensory analysis revealed that the attributes of color, aroma and flavor of the cookies were well evaluated, remaining within the hedonic preferences of "I liked it slightly" to "I liked it very much". Formulations with up to 40% chickpea flour added showed promising results in terms of texture and flavor, indicating good consumer acceptance. The production of cream crackers with chickpea flour can offer the food industry an opportunity to provide healthy and nutritious products.
MOLECULAR MODELING AND IN SILICO HUMAN AND ENVIRONMENTAL TOXICOLOGICAL STUDY FOR THE ANTIBIOTICS TRIMETHOPRIM AND SULFADOXINE
Authors: Araujo Laura Faria , Rosa José Felipe Leite Ferreira , Prates Ludmilla Louise Cerqueira Maia , Motta Luiz Frederico
Published: January 2025

Sulfadoxine in combination with trimethoprim is commonly used for broad-spectrum antimicrobial therapy in veterinary medicine. Although widespread resistance limits its use in ruminants, the combination is still useful in the treatment of gastrointestinal and respiratory infections in calves, including neonatal colibacillosis. The pharmacokinetic profile of sulfadoxine and trimethoprim differs from each other due to their chemical properties: sulfadoxine acts as a weak acid while trimethoprim is a weak base, thus concentrating in different sites in the body. Sulfadoxine and trimethoprim are two antimicrobial agents that are often used in combination due to their different mechanisms of action, acting synergistically against bacterial infections. The package inserts of both national and international companies state that the pharmaceutical product containing the two antibiotics has as its target of action the treatment of respiratory and gastrointestinal diseases in cattle and horses. One of the major challenges is related to the fact that antibiotics produced by the pharmaceutical industry result in antibiotic residues in the environment, both in water bodies and in soil. These residues contaminate the food chain, affecting fish, crustaceans and even organisms such as Tetrahymena pyriformis , a protozoan widely distributed in freshwater environments. This contamination mechanism is very worrying because it not only compromises the health of ecosystems, but will also affect humans who consume contaminated food. The in silico toxicological study revealed that the compounds did not present toxicity in the AMES Test, did not present carcinogenicity and did not have Acute Oral Toxicity.

Published: January 2025

The fraction of the world population affected by type 2 diabetes mellitus and its tendency to increase significantly in the coming decades strongly encourages improvements in the synthesis of drugs for glycemic control. The transfer of batch production to continuous processes in microreactors allows for reduced synthesis time and better yield. In this article, four microreactor designs were proposed — maze, sheet, honeycomb, and serpentine with honeycomb — to enable the synthesis of drugs in a single microreactor with a volume greater than 1 mL. The mixing quality of the prototypes was evaluated by simulating their residence time distributions (RTDs) through computational fluid dynamics (CFD). The RTDs were obtained as a response to the step of a methylene blue-like tracer and maintaining a spatial time of 20 min. In the sheet, honeycomb, and serpentine with honeycomb designs, preferential flow paths were formed, evidenced by the structure of the velocity field and the average residence time of less than 20 min. Their fluid dynamics behaviors were hybrids between the ideal models of a piston flow reactor and a perfectly stirred mixing tank. The labyrinth design has a pressure drop seven times higher than the others because it allocates all the fluid in a single long channel, but it promoted mixing of the streams with the greatest homogeneity in the available volume and with a deviation of 0.36% between the mean residence time and the spatial time, being the most promising design for drug synthesis among those proposed.

Effects of Urban Illumination on Insect Populations: AI-powered Insights into Environmental Challenges and Solutions
Authors: Dey Sayon , Mahato Nityanando , Chakraborty Gourab , Debnath Shouvik
Published: January 2025

Artificial urban lighting seriously disrupts insect populations, creating a cascade effect on ecosystems and biodiversity. This research explores the many ecological challenges presented by urban lighting in terms of how it influences the behavior, physiology, and population dynamics of insects. Urban lighting changes behavioral patterns such as foraging, mating, and navigation, thereby affecting nocturnal activity and vulnerability to predators. This light disrupts insect circadian rhythms physiologically, impairs hormonal regulation, and affects their reproductive success. That jeopardizes their survival and fitness as a population while having adverse population dynamics in abundance and diversity decline that ripple down the food web, ultimately destabilizing ecosystems. Using AI approaches driven by data, the study seeks to understand, predict, and mitigate these effects. Advanced pattern recognition and risk modeling become facilitated with the aid of AI tools in adaptive lighting systems with the potential for reduced harm to the environment. The potential in creating sustainable solutions to urban lighting with regard to ecological integrity alongside human needs, this work thus sets forth a new dimension for such issues as calls for inter-disciplinary cooperation by highlighting the pressing nature of technological innovation into ecological understanding. Through the presentation of a comparative analysis of current mitigation strategies, we are able to identify gaps and suggest future directions for urban ecological management. These include biodiversity-sensitive lighting designs, integration of AI-based monitoring systems, and policy frameworks that prioritize ecosystem health alongside urban development.

Authors: M. P Nasja. , Babu Dinesh , I. P Abdul Razak.
Published: January 2025

The Indian coastal regions harbor diverse species of sea turtles, among which Olive Ridley turtles are prevalent and commonly encountered in the coastal waters of Kerala and the Lakshadweep Islands. These turtles exhibit a preference for nesting on expansive beaches and sandy areas situated at river mouths. Our study area, located in the Irringal village of Kozhikode district in North Kerala, overlooks the Arabian Sea and lies adjacent to the Kottapuzha River. Here, the local community has undertaken a conservation initiative known as Theeram Prakriti Samrakshana Samithi (TPSS) to safeguard Olive Ridley turtles during their nesting period. During this study, we investigated the status of Olive Ridley turtle nesting grounds and populations in Kolavipalam surveying beach from 2019 to 2023. We recorded the number of OliveRidley sea turtle nestings during this period, collected the eggs, and assessed the hatching success from the artificial hatchery. The mean annual number of eggs hatched was 54.4 ± 23.27 and the overall nesting success was 25.73%.  The study revealed a significant decline in nesting turtles compared to previous years, with only 1-2 egg-laying turtles observed yearly. Median hatch success declined dramatically from 80.21% during the earlier period to 36.41% during this study period. Our analysis identified various challenges affecting turtle nesting, including the construction of sea walls, the development of beach areas for tourism, and changes in rainfall patterns. As a result, turtles were forced to nest closer to the shoreline, making their nests more vulnerable to waves and flooding. These findings emphasized the urgent need for increased conservation efforts to safeguard these endangered sea turtles, particularly in areas like Kolavipalam, which were once ideal nesting sites.

The Role of Job Satisfaction in Mediating the Influence of Human Relations, Work Ethic, and Organizational Culture on Employee Performance at PT. XYZ
Authors: Andrefson Edo , Ramadhi Ramadhi
Published: January 2025

This study aims to analyze the effects of human relations, work ethic, and organizational culture on job satisfaction and employee performance at PT. XYZ. The research uses a quantitative approach with an explanatory design. The population consists of 98 employees, and the entire population is used as the sample due to the small size, employing a saturated sampling technique. Data analysis is conducted using SmartPLS 4.0 (Partial Least Squares) to examine structural models and relationships between the variables. The results show that human relations, work ethic, and organizational culture significantly affect job satisfaction. Job satisfaction, in turn, has a significant impact on employee performance and can mediate the effect of human relations and organizational culture on performance. However, work ethic does not significantly affect employee performance, and human relations do not mediate this relationship.

Background: Nausea and vomiting are among the most common complications after surgery. Objectives: The aim of this study was to investigate the effectiveness of chamomile in reducing the incidence and severity of nausea and vomiting after middle ear surgery. Methods: A total of 110 patients who met the inclusion criteria were randomly assigned to either the chamomile or placebo group. Group A consumed chamomile drops (500 mg), while group B consumed cornstarch with 30 mL of water, one hour before surgery. The severity of nausea and frequency of vomiting were recorded at recovery (time of zero), 1, 2, 4, and 6 hours after surgery using the Rhodes Index. Data were analyzed using SPSS v.21 software, paired t-tests, and chi-square tests. Results: A total of 110 patients were included, with an average age of 36.14 ± 10.3 years (group A) and 34.28 ± 13.3 years (group B). There was no statistically significant difference between the chamomile and placebo groups in terms of the severity of nausea and the frequency of vomiting immediately after recovery (time of zero), 1, 2, and 6 hours after surgery (P > 0.05). However, 4 hours post-surgery, the severity of nausea in the chamomile group was lower than in the placebo group, and a statistically significant difference was observed between the two groups (P = 0.03). No gastrointestinal side effects were reported. Conclusions: Based on the results of this study, chamomile can be used to reduce nausea and vomiting after middle ear surgery, given its availability and low cost.

Background: At the onset of the COVID-19 pandemic, a misunderstanding emerged, suggesting that the consumption of opioid combinations might have a protective effect against COVID-19. Objectives: To identify prognostic factors associated with in-hospital mortality among confirmed COVID-19 patients with a history of opioid combination consumption in southern Iran. Methods: This retrospective cross-sectional study, conducted between September 2020 and March 2021, included patients over 14 years of age with a confirmed diagnosis of COVID-19 who were admitted to Shahid Faghihi Hospital in southern Iran (affiliated with Shiraz University of Medical Sciences). Patients with incomplete or unreadable medical records were excluded. Data were extracted from medical files and recorded in a structured data collection form comprising three main sections: (1) Demographic characteristics (e.g., age, gender, comorbidities, smoking status), (2) clinical and paraclinical findings, and (3) patient outcomes. Statistical analysis was subsequently performed. Results: Of 1,048 patients with confirmed COVID-19, 98 (8.55%) reported a history of opioid combination consumption. The mean ± SD age was 61.40 ± 14.50 years, and 81 (82.7%) were male. Thirty patients (30.6%) died in the hospital (P < 0.001). A comparison of survivors and non-survivors revealed that the mean age was significantly higher in non-survivors (P = 0.004). Non-survivors were more frequently admitted to the ICU (P = 0.001), and their mean length of ICU stay was significantly longer (P = 0.03). Multiple logistic regression analysis identified C-reactive protein (CRP) (OR = 0.92, P = 0.02) as the only independent predictor of mortality among opioid combination users with confirmed COVID-19. Conclusions: Among confirmed COVID-19 patients with a history of opioid combination consumption, the CRP level was the sole independent predictor of in-hospital mortality.

Background: Candida species are a leading cause of fungal infections worldwide. Candidiasis, the disease caused by Candida, represents a significant public health concern globally. Candida albicans is the most common causative agent, responsible for 50 - 90% of invasive candidiasis cases. Candida albicans employs various virulence factors to adhere to, invade host tissues, and cause disease. Objectives: This study aimed to detect and compare the virulence factors of C. albicans, including hydrophobicity, biofilm formation, ergosterol content, and secretory enzymes, in clinical and environmental samples. Methods: A total of 105 clinical and 165 environmental samples suspected of containing C. albicans were collected from Imam Khomeini Hospital in Ahvaz, Iran. The isolates were evaluated for five potential virulence factors: Ergosterol content, cell surface hydrophobicity (CSH), biofilm formation, protease activity, and phospholipase activity. Results: Sixty C. albicans isolates were identified, consisting of 30 clinical and 30 environmental isolates. Biofilm production was observed in 100% of clinical isolates and 80% of environmental isolates (P < 0.001). Protease activity was detected in 66.6% of clinical isolates and 76.7% of environmental isolates (P = 0.008). Phospholipase activity was present in 60% of clinical isolates and 76.7% of environmental isolates (P = 0.262). Clinical isolates exhibited higher CSH (66.4 ± 9.8) compared to environmental isolates (47.7 ± 17.0) (P < 0.001). The ergosterol content was 1.2 ± 0.5 in clinical isolates and 1.1 ± 0.3 in environmental isolates. Conclusions: Biofilm formation was a consistent characteristic of clinical isolates, while phospholipase and protease activity were more prevalent in environmental C. albicans isolates. The results suggest possible cross-contamination between patients and the environment, as the virulence factors of clinical and environmental isolates were similar.

Background: Acute mediastinitis is a life-threatening condition requiring urgent intervention. Objectives: This study aims to describe the clinical, laboratory, imaging, and microbiological characteristics, as well as treatment outcomes, of acute mediastinitis cases. Methods: A retrospective, descriptive study was conducted on 32 patients treated at the University Medical Center Ho Chi Minh City from February 2016 to April 2024. Data were collected on patient demographics, clinical features, laboratory results, imaging findings, microbiological cultures, and treatment outcomes. Results: The mean age was 55.7 years, with males comprising 59.4% of cases. Fever and chest pain were the most common symptoms. Staphylococcus aureus was the most frequently identified organism. Computed tomography (CT) scans typically showed mediastinal air-fluid levels and fat stranding. Surgical interventions included neck drainage and thoracotomy. Complications included severe sepsis, septic shock, and pneumonia, with a mortality rate of 9.4%. Conclusions: Acute mediastinitis predominantly affects older males and presents significant clinical and diagnostic challenges. Effective multidisciplinary management is crucial for improving patient outcomes. This study provides valuable insights into the characteristics and treatment of acute mediastinitis in a Southeast Asian region.

Background: In 2020, COVID-19 was a major cause of absenteeism. Objectives: To investigate the factors affecting the time taken to return to work after COVID-19 hospitalization. Methods: This was a cross-sectional study conducted on 320 working individuals (295 men and 25 women) hospitalized in Yazd province, Iran, due to COVID-19 between September 2020 and March 2021. All patients who met the inclusion criteria and provided consent were enrolled in the study via census. The inclusion criteria were: A definite or probable diagnosis of COVID-19 and hospitalization for no reason other than COVID-19. The required information was collected through phone interviews using a researcher-developed questionnaire that included demographic, occupational, recent COVID-19 infection, and return-to-work information. Data were analyzed using SPSS software. Results: The average duration of absenteeism was 31.67 ± 33.47 days. Univariate regression analysis revealed a significant relationship between absenteeism lasting more than 21 days and several factors: Age (P = 0.005), gender (P = 0.044), marital status (P = 0.005), number of dependents (P < 0.001), diabetes (P = 0.004), BMI (P = 0.031), job experience (P < 0.001), type of employment (P = 0.008), workplace respiratory exposures (P = 0.042), lower respiratory symptoms (P = 0.024), duration of hospitalization and medication use (P < 0.001), pulmonary complications (P < 0.001), and mental complications (P = 0.004). After adjusting for confounding factors, only three factors were significantly associated with a delay in return to work of more than 21 days: Duration of medication use (P < 0.001), presence of pulmonary complications (P = 0.014), and presence of psychological complications (P = 0.040). Conclusions: The severity of the disease, as indicated by the duration of medication use for COVID-19 after discharge, and the presence of pulmonary and psychological complications, directly influenced the return to work after COVID-19.
