This study focused on vaccine hesitancy and decision regret about the COVID-19 vaccine among nursing students (BScN and MScN) and Registered Nurses (RNs) in Italy. The primary aim was to describe decision regret and vaccine hesitancy among these groups and to understand what influences vaccine hesitancy. Data were collected through an e-survey conducted from March to June 2024. The Decision Regret Scale and the Adult Vaccine Hesitancy Scale were employed to assess regret and hesitancy levels, assessing trust, concerns, and compliance regarding vaccination. Among the participants, 8.64% were not vaccinated. The results indicated moderate to high levels of decision regret and diverse levels of trust, concerns, and compliance with COVID-19 vaccination. Structural equation modeling revealed that decision regret significantly predicted Trust (R2 = 31.3%) and Concerns (R2 = 26.9%), with lower regret associated with higher trust and lower concerns about vaccine safety. The number of COVID-19 vaccine boosters was a significant predictor of Trust and Concerns, with more boosters associated with higher trust and lower concerns. MScN students exhibited higher Compliance compared to RNs (R2 = 2.9%), highlighting the role of advanced education. These findings suggest that addressing decision regret and providing comprehensive vaccine information could enhance trust and compliance.

Published: September 2024

A nanoliter liquid chromatography–high resolution mass spectrometry-based method was developed for quantitative proteomics analysis of COVID-19 vaccines. It can be used for simultaneous qualitative and quantitative analysis of target proteins and host cell proteins (HCPs) in vaccine samples. This approach can directly provide protein information at the molecular level. Based on this, the proteomes of 15 batches of COVID-19 inactivated vaccine samples from two companies and 12 batches of COVID-19 recombinant protein vaccine samples from one company were successfully analyzed, which provided a significant amount of valuable information. Samples produced in different batches or by different companies can be systematically contrasted in this way, offering powerful supplements for existing quality standards. This strategy paves the way for profiling proteomics in complex samples and provides a novel perspective on the quality evaluation of bio-macromolecular drugs.

Background: Varicella infections follow a benign course in around 90% of cases, with more severe forms occurring in adults. To identify potential pockets of susceptibility and to improve targeted immunization strategies, this study aims to critically assess immunological status by evaluating varicella seroprevalence among adults (18–99 years) in the province of Florence (Italy), nearly a decade after Tuscany introduced the vaccination program. Methods: A convenience sample of 430 subjects aged 18 to 94 years (mean age 51.8 ± 18.8 years), stratified by age and sex (53.7% of subjects were female; N = 231), was collected between 2018 and 2019. Sero-analytical analyses were conducted utilizing EUROIMMUN Anti-VZV ELISA (IgG) kits. Results: Most of them were of Italian nationality (87.4%; N = 376). Among the 430 tested samples, 385 (89.5%) were positive and 39 (9.1%) were negative. The remaining six sera (1.4%), confirmed as equivocal, were excluded from further analysis. No significant differences were found based on sex (p-value = 0.706) or nationality (p-value = 0.112). The application of trend tests (Mantel–Haenszel; Kendall Tau-b) showed a significant trend (p < 0.024 and p < 0.032, respectively), with an increasing probability of finding a positive anti-varicella serological status passing from a lower age group (84.2%) to a higher one (93.0%). By considering the female population aged 18–49 years, the seroprevalence of anti-varicella antibodies was found to be 88.4%, with a susceptibility of 11.6%, highlighting the risk of acquiring infection during pregnancy. Conclusions: The introduction of varicella vaccination has had a significant impact on public health in Tuscany and in Italy more generally. However, further efforts should be made to reduce the number of individuals still susceptible in adulthood, with particular attention given to women of childbearing age and the promotion of vaccination through mass and social media and institutional websites.

MTs are prevalent in dogs, representing the most frequent oral malignancy, compared to cats, in which ocular melanomas predominate. This study investigates the canine and feline MT epidemiology (2005–2024) of cases submitted to the Veterinary Pathology Service (University of Perugia). Among the canine neoplasms, 845 (4%) were melanocytic: 329 (39%) melanocytomas; 512 (61%) melanomas. Of these, 485 (57%) were cutaneous (4% of canine cutaneous neoplasms), 193 (23%) were oral (50% of oral canine neoplasms), and 104 (12%) were mucocutaneous. The average age of affected dogs was 10 years. Older dogs were more likely to have melanomas compared to melanocytomas (p < 0.001). There were 60 (1%) feline MTs: 6 (10%) melanocytomas; 53 (88%) melanomas. Of these, 29 (48%) were cutaneous (1% of feline cutaneous tumors), 18 (30%) were ocular, and 9 (15%) were oral (22% of feline oral tumors). The average age of affected cats was 11 years. In dogs, mucocutaneous melanomas were more common compared to cutaneous ones (p < 0.05); oral melanomas were more common compared to all other sites (p < 0.001). In cats, ocular melanomas were more common compared to cutaneous ones (p < 0.05). Our study provides the MT prevalence in a selected canine and feline population, revealing MT epidemiological patterns, highlighting species-specific differences in the tumor prevalence, localization, and age distribution.

This study investigates the susceptibility of common pathogens to totarol and assesses its clinical effectiveness in promoting wound healing in client-owned dogs with open wounds. Twenty-three client-owned dogs with open wounds were divided into two groups: (1) the treatment group (T-group) and (2) the control group (C-group). Clinical samples were collected from the wounds for the bacterial identification and determination of the minimum inhibitory concentrations (MICs) of totarol. In the T-group, wounds were treated with standard wound care together with the application at a dosage of 0.3 mL (two sprays) of commercial totarol product per 25 cm2 of the wound area. The C-group received only standard wound care. This in vitro study found that totarol exhibited antimicrobial activity against both standard pathogens and clinical wound pathogens. The MIC values of totarol dissolved in absolute ethyl alcohol were 4 µg/mL for Gram-positive pathogens and ranged from 256 to 512 µg/mL for Gram-negative pathogens. However, the MIC values of the commercial totarol product ranged from 512 to 1024 for both Gram-positive and Gram-negative pathogens. Clinically, the use of a commercial totarol product as an adjunctive therapy significantly improved wound healing, as indicated by a greater percentage of wound area reduction (p < 0.05). From day 2 to day 7 of the treatment, the percentage of wound area reduction differed significantly between the T-group and the C-group. At the end of the study, the average percentage of wound area reduction was 69.18% ± 18.12 and 41.50% ± 20.23 in the T-group and C-group, respectively. The finding of this study illustrates the antimicrobial properties of totarol and its product against prevalent wound pathogens. These results suggest the potential of totarol as an adjunctive option for canine wound care.

Published: September 2024

The accessibility and deployment of complex hydrological models remain significant challenges in water resource management and research. This study presents a comprehensive workflow for converting Python-based hydrological models into web APIs, addressing the need for more accessible and interoperable modeling tools. The workflow leverages modern web technologies and containerization to streamline the deployment process. The workflow was applied to three distinct models: a GRACE downscaling model, a synthetic time series generator, and a MODFLOW groundwater model. The implementation process for each model was completed in approximately 15 min with a reliable internet connection, demonstrating the efficiency of the approach. The resulting APIs provide standardized interfaces for model execution, progress tracking, and result retrieval, facilitating integration with various applications. This workflow significantly reduces barriers to model deployment and usage, potentially broadening the user base for sophisticated hydrological tools. The approach aligns hydrological modeling with contemporary software development practices, opening new avenues for collaboration and innovation. While challenges such as performance scaling and security considerations remain, this work provides a blueprint for making complex hydrological models more accessible and operational, paving the way for enhanced research and practical applications in hydrology.

Published: September 2024

The Xiao Bei mainstream, located in the middle reaches of the Yellow River, plays a vital role in regulating the quality of river water. Our study leveraged 73 years of hydrological data (1951–2023) to investigate long-term runoff trends and seasonal variations in the Xiao Bei mainstream and its two key tributaries, the Wei and Fen Rivers. The results indicated a significant decline in runoff over time, with notable interannual fluctuations and an uneven distribution of runoff within the year. The Wei and Fen Rivers contributed 19.75% and 3.59% of the total runoff to the mainstream, respectively. Field monitoring was conducted at 11 locations along the investigated reach of Xiao Bei, assessing eight water quality parameters (temperature, pH, dissolved oxygen (DO), chemical oxygen demand (COD), ammonia nitrogen (NH3-N), total phosphorus (TP), permanganate index (CODMn), and 5-day biochemical oxygen demand (BOD5)). Our long-term results showed that the water quality of the Xiao Bei mainstream during the monitoring period was generally classified as Class III. Water quality parameters at the confluence points of the Wei and Fen Rivers with the Yellow River were higher compared with the mainstream. After these tributaries merged into the mainstream, local sections show increased concentrations, with the water quality parameters exhibiting spatial fluctuations. Considering the mass flux process of transmission of the quantity and quality of water, the annual NH3-N inputs from the Fen and Wei Rivers to the Yellow River accounted for 11.5% and 67.1%, respectively, and TP inputs accounted for 6.8% and 66.18%. These findings underscore the critical pollutant load from tributaries, highlighting the urgent need for effective pollution management strategies targeting these tributaries to improve the overall water quality of the Yellow River. This study sheds light on the spatiotemporal changes in runoff, water quality, and pollutant flux in the Xiao Bei mainstream and its tributaries, providing valuable insights to enhance the protection and management of the Yellow River’s water environment.

The article presents the features of the COVID-19 epidemic process in the Moscow Region (MO) for the period from March 2020 to December 2023. It has been established that the dynamics of the incidence of a new coronavirus infection is characterized by periods of growth and decline in morbidity of varying intensity and duration, which coincides with the appearance and circulation of new variants of the SARS-CoV-2 virus among the population. Similar periodic ups and downs have been revealed in the dynamics of mortality. It was noted that the lowest mortality rate was observed in March 2023 (0,02 %) and the highest in February 2021 (4,26 %), which was also associated with the circulation of various variants of the coronavirus. There have been increases in morbidity both in the cold season and in the summer months, which does not fully correspond to a seasonal disease with airborne transmission. It was revealed that the highest incidence was observed among the adult working population. At the same time, the incidence of children has increased since 2022, especially under the age of 1 year. Vaccination coverage of the M. O. population at the end of 2022, it amounted to 56,9 %, and collective immunity tended to decrease from 46,04 % in December 2021 to 6,07 % in December 2022. The correlation coefficient between the morbidity of the population and those vaccinated against COVID-19 in the Ministry of Defense was 0,38 %, between mortality and those vaccinated was minus 0,08, which indicates a weak effect of vaccination on morbidity and mortality.

Nutrition optimization by providing workers with specialized products enriched with vitamin and mineral components has great importance in solving problems in the health condition of workers in the Arctic zone. Objective: to evaluate the effect of vitamin-mineral complex (VMC) containing vitamins (А, D, В1, В2, В3, В6, В12 and C) and minerals (Fe, I, Se) on physiological indicators and indicators of orientative-research behavior of laboratory animals which characterize the adaptation process. Object of the study: white laboratory rats of «Wistar» type, organized into 4 groups: two experimental groups, kept in conditions of low air temperature (4–6 °C) and unusual photoperiodism, which received VMC with the diet, and two control groups, where animals did not receive VMC. One of them was maintained under «Northern Territories» conditions, the second — under comfortable conditions (usual photoperiodism and temperature +22…+24 °C). Indicators of body weight and temperature and functional activity of the nervous system were studied using the «Open Field» method. Statistical analysis was performed using standard application programs Statistica 10.0 with calculation of median (Me) and percentile interval. Acceptable level of reliability of the results was considered to be the probability of differences of 95 % and higher (p ≤0.05). The animals of the experimental groups showed constancy of temperature balance, statistically significantly lower anxiety level indicators, higher level of emotional activity compared to the animals of the control group. The gender peculiarities of anxiety indices were revealed, which were more pronounced in males, whose research activity was increased in the conditions of «polar night» and sharply decreased in the conditions of «polar day». The obtained stress-protective effect of intake of VMC containing daily norm of vitamins (C, Е, В1, В2, В3, В6, В9, В12, D3, carotene) and minerals (zinc, iron, iodine, selenium) indicates the safety and high significance of the use of VMC in the diet of shift workers in the Arctic zone.

Published: September 2024

Lumbar disc hernia represents one of the most frequent neurosurgical pathologies, consisting of a posterior migration of the nucleus pulposus which protrudes through the surrounding protective connective tissue. The patient usually exhibits leg pain, paraesthesia or a variable degree of discomfort at the lower extremities, those clinical characteristics are correlated to the extent of nucleos pulposus protrusion. Regarding neuroimaging diagnosis, the gold standard of evaluation is Magnetic resonance imaging in different sequences which highlights a precise topography of the herniated disc. Currently, in a well-digitalized era, machine learning and deep learning algorithms are used to assess the sensibility of detecting a lumbar disc hernia, with promising results. In those cases requiring surgical intervention, besides the open lumbar microdiscectomy, a less invasive surgical approach regularly used in the medical practice is endoscopic lumbar discectomy, being limited to cases where a wide intraoperative perspective is not necessary. In the actual neurosurgical management, postoperative complications following lumbar disc hernia surgery are rare and accessible to manage.

Published: September 2024

Abstract
Background: The Craniovertebral Junction (CVJ) is prone to various pathologies, including instability and congenital anomalies. Understanding these conditions and their management strategies is critical for effective treatment.
Materials and Methods: A systematic search was conducted in Science Direct and PubMed databases following PRISMA guidelines. Inclusion criteria encompassed studies addressing craniovertebral instability and associated pathologies. Six systematic investigations were assessed for methodological quality. Data extraction involved 702 patients with CVJ issues, among which 129 had related conditions, while 279 displayed normal CVJ. Surgical interventions encompassed various techniques such as C1-C2 fixation, posterior decompression, and screw placements.
Results: Among 702 patients studied, atlantoaxial subluxation, basilar invagination, and odontoid fractures were observed in 129 cases. Surgical treatments showed favorable outcomes, with fusion achieved within a year post-surgery for both C1-C2 fixation techniques and posterior decompression strategies. Studies highlighted successful outcomes in cases of cervical myelopathy, especially with early occipitocervical fusion.
Conclusion: Managing atlantoaxial instability remains a debated topic, with varying success rates observed in different surgical interventions. Recommendations emphasize the importance of stabilization techniques and imaging modalities for effective preoperative planning and postoperative care. However, limitations in the available data underscore the need for further research to refine treatment strategies for better patient outcomes in this complex area of spinal pathology.

Background: Posterior communicating artery (PCom) aneurysms are prevalent intracranial aneurysms, frequently leading to subarachnoid haemorrhage and third nerve palsy. "True" perforators originating directly from the PCom aneurysmal sac are rare and pose unique surgical challenges. We present two illustrative cases where "true" PCom perforators were identified during surgery, necessitating tailored microsurgical approaches.
Case Reports: In case one, a 35-year-old female presented with a large PCom aneurysm. During surgery, a modified clipping technique successfully preserved a perforator originating from the aneurysmal sac. In case two, a 36-year-old male with a PCom aneurysm was found to have a perforator supplying the mesial temporal cortex. Sacrificing this perforator was necessary for aneurysm clipping.
Conclusion: This paper underscores the rarity of "true" PCom perforators and their impact on microsurgical approaches. Preoperative imaging techniques often fail to detect these small-calibre vessels, highlighting the importance of intraoperative identification. Tailored approaches based on individual anatomy and clinical context are essential. While endovascular procedures provide alternatives, adaptability in microsurgical techniques remains crucial for cases requiring intraoperative perforator management. Overall, understanding the complex vascular intricacies of PCom aneurysms, including "true" perforators, is vital for neurosurgeons. The delicate balance between preservation and necessity, along with ongoing research for improved preoperative identification, stands as the cornerstone for enhancing surgical outcomes in these complex cases.

MECHANICAL PROPERTIES OF ULTRA-HIGH PERFORMANCE FIBER-REINFORCED CONCRETE WITH DIFFERENT TYPES OF STEEL FIBER
Authors: Soloviev V. , Matiushin E.
Published: September 2024

The article examines the influence of steel fiber type and volumetric content on the mechanical properties of UHPFRC. Five fiber types were used: corrugated 15/0.3 and 22/0.3 mm, straight 13/0.3 and 13/0.2 mm, and hooked-end 30/0.5 mm. The fiber volume content ranged from 0 to 3%. During the experimental studies, compressive strength, flexural strength, as well as the flexural fracture energy were determined. It has been discovered that an increase in the volumetric content of steel fiber results in an enhancement of all the properties under consideration, irrespective of the type of fiber. The fiber has the biggest effect on the bending fracture energy and the least on the compressive strength. Linear relationships between the mechanical characteristics of UHPFRC and the fiber factor were established, which reflects the volumetric content, length, and diameter of an individual fiber. The slope angle of the approximating lines of the “compressive strength-fiber factor” and “flexural strength-fiber factor” relationships takes on different values depending on the type of fiber used. The highest slope angle is found for corrugated fiber. It was discovered that there is a threshold value of the fiber factor, upon reaching which the steel fiber leads to an increase in the flexural strength of the UHPFRC. According to a generalized quality criterion it has been determined that corrugated fiber with dimensions of 22/0.3 mm is the optimal substitute for straight fiber 13/0.2 mm, which is widely utilized for the production of Ultra-High Performance Fiber-Reinforced Concrete
TECHNIQUE FOR ANALYSIS OF HYBRID ROOF STRUCTURE OF THE STRUTTED TYPE
Authors: Chesnokov A. , Mikhailov V.
Published: September 2024

Hybrid building structures have advantages in terms of efficiency of using high-strength materials and reducing deformations under load. To expand the scope of their practical application, it is necessary to improve techniques for structural analysis and design methods. The object of the present research is a hybrid structure of the strutted-type. The top chord of the structure is formed by rectilinear beams arranged in radial direction and pivotally connected in the ridge joint. The bottom chord consists of high-strength cable elements and hinge struts. For the static analysis of the structure, its flat model is adopted. The static indeterminacy is solved by means of the method of redundant reactions. The applicability of the method is justified by restriction of structural deformations implied by the serviceability limit state. Analytical expressions are proposed to determine the forces and bending moments in the main structural elements. The resulting expressions are unified to perform the structural analysis under pre-stress and external loads by means of supplementary parameters introduced. An improved technique for finding the matrix of coefficients and the vector of free terms of the canonical system of the method of redundant reactions is proposed. The technique allows automating the calculation. A method for taking into account flexible cable elements is developed. The method includes step-by-step eliminating of compressed cables from the design scheme. The results of the work contribute to the development of hybrid strutted-type structures and can be used for developing optimal design solutions, as well as to identify patterns of stress-strain state of the hybrid structures by means of the numerical simulation.
A Single-Center Retrospective Study to Identify Causes of Sex Differences in the Living Kidney Donor Evaluation Process
Authors: Chumdermpadetsuk Ritah R. , Montalvan Adriana , Canizares Stalin , Chopra Bhavna , Pavlakis Martha , Lee David D. , Eckhoff Devin E.
Published: September 2024

Key Points

Female overrepresentation in living kidney donation stems from higher self-referral rates, not differences in approval or follow-through.

Male volunteers are not more likely to be declined as donors due to medical contraindications, contrary to common assumptions.

Engaging more male volunteers in living donation could expand access to kidney transplantation and reduce waitlist times.

Background

Multiple studies have shown that female volunteers are living donors (LDs) for kidney transplantation at higher rates than male volunteers. However, the underlying reasons for this observation are not well understood. We examined the LD evaluation process to determine the point at which sex imbalance arises. On the basis of a previous study, we hypothesized that both sexes are equally likely to become approved as LDs, but female volunteers are more likely to follow through with donation.

Methods

This is a single-institution retrospective chart review of self-referrals for LD evaluation between January 2009 and December 2022. Self-referrals were identified using the Organ Transplant Tracking Record database and cross-referenced with billing data. Exclusion at each stage of evaluation was recorded and compared between sexes using log binomial regression; unadjusted and adjusted (for donor age, race, ethnicity, relationship to recipient, and recipient sex) risk ratios with 95% confidence interval were determined.

Results

One thousand eight hundred sixty-one self-referrals were reviewed, including 1214 female (65.2%) and 647 male (34.8%) volunteers, resulting in 146 approvals and 125 donations (76/125, 60.8% female, 49/125, 39.2% male). Adjusted risk ratios indicated no significant differences between sexes in completing medical and/or psychosocial workup, having medical and/or psychosocial contraindications, being approved for donation, and proceeding with donation. The top medical contraindications for both sexes were obesity, hypertension, and nephrolithiasis.

Conclusions

Female overrepresentation among LDs is likely due to the 1.9 times higher rate of self-referral for evaluation. After this point, both sexes were equally likely to complete workup, be approved, and follow through with donation. Increased efforts to engage male volunteers at the initial self-referral stage has the potential to expand access to LD kidney transplantation.

Association of Smoking with Chronic Kidney Disease Stages 3 to 5: A Mendelian Randomization Study
Authors: Zhang Zhilong , Zhang Feifei , Zhang Xiaomeng , Lu Lanlan , Zhang Luxia
Published: September 2024

Background:
Previous studies suggested that smoking behavior (e.g., smoking status) was associated with an elevated risk of chronic kidney disease (CKD), yet whether this association is causal remains uncertain.
Methods:
We used data for half million participants aged 40 to 69 years from the UK Biobank cohort. In the traditional observational study, we used Cox proportional hazards models to calculate the associations between 2 smoking indices—smoking status and lifetime smoking index and incident CKD stages 3 to 5. Mendelian randomization (MR) approaches were used to estimate a potential causal effect. In one-sample MR, genetic variants associated with lifetime smoking index were used as instrument variables to examine the causal associations with CKD stages 3 to 5, among 344,255 UK Biobank participants with white British ancestry. We further validated our findings by a two-sample MR analysis using information from the Chronic Kidney Disease Genetics Consortium genome-wide association study.
Results:
In the traditional observational study, both smoking status [hazard ratio (HR): 1.26, 95% confidence interval (CI): 1.22 to 1.30] and lifetime smoking index (HR: 1.22, 95% CI: 1.20 to 1.24) were positively associated with a higher risk of incident CKD. However, both our one-sample and two-sample MR analyses showed no causal association between lifetime smoking index and CKD (all
P
> 0.05). The genetic instruments were validated by several statistical tests, and all sensitivity analyses showed similar results with the main model.
Conclusion:
Evidence from our analyses does not suggest a causal effect of smoking behavior on CKD risk. The positive association presented in the traditional observational study is possibly a result of confounding.

Published: September 2024

Background: With a global prevalence of mental disorders among adolescents, exacerbated by the coronavirus disease 2019 (COVID-19)’s impact, understanding the dynamics of seeking assistance is crucial. Therefore, this study determined the status of the help-seeking intention and the factors affecting it among high school students in Saveh (center of Iran). Methods: In this cross-sectional study conducted in 2023, 400 students from different high schools were selected by a multi-stage stratified random sampling procedure. They were studied using the Short Form of Mental Health Continuum Questionnaire (MHC-SF), Attitude Toward Seeking Professional Psychological Help Questionnaire (ATSPPH), Help-seeking Intention Questionnaire (GHSQ), and perceived barriers related to mental health services. Data were analyzed via SPSS 21 software using linear regression and descriptive statistical methods. Furthermore, P<0.05 was considered statistically significant. Results: The mean score attitude toward mental health services, perceived barriers to mental health services, and positive mental health were 33.8±5.5, 23.5±3.8, and 42.36±10.39, respectively. Close friends were favored for informal help-seeking (4.3±0.97), while doctors preferred formal help-seeking (3.4±0.91). Furthermore, attitude toward mental health services was the most important predictor of formal help-seeking (P value<0.001; β=3.89), while positive mental health was the most important predictor of informal help-seeking (P value<0.001; β=2.93). Conclusion: The findings of this study identified friends, family, and doctors as primary sources of informal and formal help-seeking among adolescents. Mental health literacy education is crucial for these groups. Given boys’ lower help-seeking intentions and the influence of attitudes and perceived barriers, comprehensive training is recommended. Hence, it is essential to incorporate mental health literacy programs within school curricula. Moreover, school counselors should receive comprehensive training to identify and address mental health issues effectively among students.

Published: September 2024

Background: Prenatal care and care behaviors can affect pregnancy outcomes. In this regard, it is crucial to identify the variables that can influence the care behaviors of pregnant women. The literature review reveals that extensive research has been conducted on the association between health literacy and care behaviors among pregnant women in Iran. However, these studies have not yet been evaluated and summarized comprehensively. Consequently, the present study aimed to investigate the impact of health literacy on care behaviors in pregnant women in Iran. Methods: This systematic review encompassed a comprehensive search of various English-language databases, including Pub Med, Scopus, Web of Science, Google Scholar, and ProQuest. The search was conducted using MESH keywords related to health literacy, along with other relevant keywords. Furthermore, Persian language databases, namely SID, Magiran, and Irandoc, were searched using the appropriate keywords. The collected data were subjected to qualitative analysis. Results: Finally, 19 articles were included. The findings showed that pregnant women with higher levels of health literacy exhibited improved adherence to various care behaviors. These behaviors included following a nutritious diet, using recommended supplements, practicing preventive measures for urinary infections, initiating prenatal care promptly, and maintaining good oral and dental hygiene. Conclusion: Health literacy is a significant factor influencing care behaviors during pregnancy. Therefore, it is recommended to incorporate health literacy as a crucial consideration when designing interventions aimed at enhancing care behaviors among pregnant women.
