Clinical Manifestations and Molecular Identification of Giardia duodenalis in Pediatric and Adolescent Cancer Patients in Southwestern Iran.

This study aimed to investigate the clinical and molecular characteristics of Giardia duodenalis (G. duodenalis) infection and identify potential risk factors in children and teenagers with malignancies in Shiraz, southwestern Iran. A total of 200 fresh fecal samples were collected from children and adolescents suffering from 32 different cancer types at Amir, Nemazee, and Saadi hospitals affiliated with Shiraz University of Medical Sciences between October 2021 and May 2022. Direct microscopy using saline and iodine wet mount was conducted, and all fecal samples were rechecked by SSU-PCR. Subsequently, a specific fragment of the tpi gene was amplified on all samples for prevalence, sequencing, and assemblage identification. Our study found a 4% (8/200) prevalence of G. duodenalis using microscopy and PCR. The molecular findings were consistent with the microscopic results. All eight positive samples with SSU-rRNA gene were also detected as positive with tpi gene and were correctly sequenced. Among the examined cancer patients, two assemblages were identified: A [sub-assemblage AI (2/8, 25%) and sub-assemblage AII (3/8, 37.5%)] and B [sub-assemblage BIV (3/8, 37.5%)]. Notably, patients were more vulnerable to G. duodenalis infection after receiving at least 8 treatment episodes (p < 0.05) and displaying gastrointestinal symptoms (p > 0.05). The demographic characteristics of cancer patients with G. duodenalis infection and the statistical conclusions were separately detailed. The small sample size and low prevalence rate in this study hindered precise epidemiological conclusions. Nonetheless, the results suggest that G. duodenalis infection among cancer patients in Shiraz city originates from humans, without any specific animal groups (C-H) involved.

Nanotechnology for thermal comfort and energy efficiency in educational buildings with a simulation and measurement approach in BSh climate

Educational buildings have a large share and impact on urban development. While research shows a significant portion of non-industrial energy consumption in these buildings, obtaining optimal thermal comfort in educational buildings remains one of the main concerns in achieving the grounds to promote students’ best performance and efficiency. Extensive research has been done in this field, however, this research presents a new approach to the diverse use of nanotechnology techniques which improve its properties and components in the buildings, aiming to reduce energy consumption and increase thermal comfort. In this paper, thermal comfort and energy consumption are evaluated in a 12-class elementary school located in Shiraz City. Aeropan and nano-Phase change materials (nano-PCMs) is used in the window glass and walls of the studied case. This evaluation presents the simulation and experimental analysis of thermal comfort (PMV) and energy consumption of three classroom alignments in the school building including the Linear-shape (LS), the Integrated Linear-shape (ILS), and the U-shaped (US) alignment. The simulation was performed using EnergyPlus 9.6 software, while the experimental data was collected using TESTO 425 device. The result of this research shows that after applying nano-PCM and Aeropan techniques in window glass and walls, the US alignment has the highest reduction in energy consumption (monthly average of 11.80%) compared to LS and ILS alignments. This alignment includes an energy consumption reduction of 12.03% in the coldest, and, 11.66% in the hottest day of the year in addition to increasing the monthly average thermal comfort of school by the use of nanomaterials.

Psychological strains after the crisis: evaluating separation anxiety among Iranian children and adolescents in the post-COVID-19 era

ObjectivesThe objective of this study was to specifically investigate Separation Anxiety Disorder (SAD), as one of the noteworthy disorders within the spectrum of anxiety disorders, among children and adolescents, after overcoming the crises caused by the Coronavirus Disease 2019 (COVID-19) pandemic. Efforts were also made to identify socio-demographic factors that could be associated with changes in SAD level and also to assess the effect of different constituting dimensions of SAD on the severity of this disorder.MethodsIn this cross-sectional study, face-to-face interviews were conducted with the parents of 317 (7-13-year-old) Iranian students, who were selected through a multi-stage random sampling method in the city of Shiraz. During the interviews, socio-demographic data were collected, and subsequently, SAD symptoms and dimensions were assessed using the Separation Anxiety Assessment Scale (Parent Version) (SAAS-P) questionnaire. Later, employing the Partition Around Medoids (PAM) statistical method, the participants were categorized into two groups with low and high levels of SAD. Also, to understand the interaction between the different dimensions of SAD, the network analysis method was employed. Finally, univariate analysis and logistic regression were utilized, with a significance level of 0.05, to determine potential associating factors with the level of SAD.ResultsThe sample included 128 girls and 189 boys with a mean age of 9.63 ± 2.63 and 9.63 ± 1.95 years respectively. Based on the PAM method, 51.1% of the participants presented a high level of SAD. According to network analysis, it was demonstrated that the “fear of abandonment” dimension plays a central role in high levels of SAD. Based on logistic regression, female gender, age ≥ 10 years, parents’ unacademic educational background, mother’s employment, and child’s history of physical/mental problems were significantly associated with the high level of SAD.ConclusionsA considerable number of the participants in this study presented a high level of SAD with the “fear of abandonment” being a key influential dimension of elevated levels of this disorder. Maternal employment, female gender, child’s history of health issues, and low parental education were identified as important contributors to the high SAD level. Considering these factors allows for more effective diagnostic and therapeutic interventions. However, the need for further studies remains crucial.

Impact of buildings’ configuration in an urban context on the spread pattern of NO2 and indoor air quality: A CFD simulation

The influence of the building’s configuration on the air flow pattern and the amount of pollutant entering the buildings was investigated. Six common forms of low-rise buildings in Shiraz City were evaluated as investigated patterns. Each of these forms were placed in four rotation modes (24 case studies in total) in an urban regular pavilion-shaped context, placed in the vicinity of an urban highway (as a source of pollutant production) and were simulated using Computational Fluid Dynamics (CFD). In this research, air velocity and NO2 concentration were considered as the air quality parameters. Steady 3-dimensional flow was used to simulate these cases using the SST k-[Formula: see text] turbulence model, which was numerically solved based on the Reynolds-averaged Navier–Stokes (RANS) equations. The CFD software used in this research was validated in comparison with wind tunnel tests and acceptable results were found. The TOPSIS multi-criteria decision-making method was used to choose the best case based on increasing the air velocity and decreasing amount of pollutant inside the building. The results show that the best and worst building forms are related to the step-shaped and the L-shaped form, respectively. The results of this research provide design solutions for architects and urban designers to improve the ventilation quality of buildings.

Transformations in urban gardens: Neoliberal influences and land use conflicts in Shiraz's Qasr al-Dasht Gardens

The extensive transformation of urban gardens is a significant element in the process of planetary urbanisation. This is driven by the constraints of a neoliberal political economy aimed at maximising the capitalistic utilisation of urban spaces. This study examines the conversion of urban gardens to paved or hard surface areas, a phenomenon described as "de-gardening". The study is conducted through a qualitative methodology that involves engagement with key stakeholders around Qasr al-Dasht Gardens in the city of Shiraz, Iran. The investigation traces the origins of these transformations to the 1960s, noting an acceleration in recent decades. The analysis identifies the pervasive influence of neoliberal urban planning and management discourse as a critical factor. This discourse redefines the value of garden spaces by escalating land costs and altering economic valuations by various social actors. Consequently, diverse social groups, ranging from traditional gardeners to modern urban developers, engage differently with these spaces. For traditional farmers, gardens are essential for livelihood, whereas for advocates of neoliberalism, these areas represent potential for investment, luxurious havens for peaceful and comfortable living, and capital accumulation. These conflicting views have led to extensive land use changes in Qasr al-Dasht Gardens. The study concludes by proposing policy measures and institutional frameworks aimed at preserving and enhancing urban gardens. Recommendations include the establishment of an independent municipal body dedicated to the gardens, forming non-governmental organisations and oversight groups, and reevaluating the "Organisation and Conservation Plan of the Qasr al-Dasht Gardens of Shiraz".

Unveiling the impact of date-specific analytics on vehicle fuel consumption and emissions: A case study of Shiraz city

Understanding the factors affecting internal combustion engine performance is crucial for improving emissions and fuel efficiency in real traffic. This paper investigates the influence of date-specific factors, such as working days and holidays on fuel consumption and emissions of a representative internal combustion engine in the context of Shiraz city. The data was collected by measuring the speed of vehicle on a specific route during peak traffic times on both working days and holidays. The determined route was calculated by a qualitative and quantitative method. K-means clustering and principal component analysis are employed to design representative driving cycles, then combining micro-trips and smoothing them to develop driving cycles. Characteristics of both driving cycles, emissions such as HC, NOx, CO, and fuel consumption were specified under a simulated vehicle model of Peugeot 206 and placed through both real driving cycles by using advanced vehicle simulation software. It has been observed that variations in fuel consumption and emissions between holidays and working days can be attributed to distinct driving patterns and characteristic parameters, such as acceleration, speed, and driving time. Contrary to common assumptions, the study found that fuel consumption was approximately 8 % higher on holidays compared to working days, primarily due to increased driving time and higher average speeds. Moreover, higher acceleration and speed on holidays led to a significant increase in CO emissions (about 36 %) and NOx emissions (about 4 %) compared to working days. However, HC emissions was found to be 27.03 % higher on working days according to lower speed. This study helps in reducing fuel consumption and emissions by uncovering internal combustion engine factors, optimizing driving patterns, and promoting sustainable transport on working days and holidays.

The Study of Genetic Affinity of Methicillin Resistance Staphylococcus Aureus Strains Isolated from Cream Pastries and Nasal Isolates at Shiraz Confectionaries

Background: Staphylococcus aureus (S. aureus) is responsible for most cases of food poisoning all around the world. These carriers and manipulated foodstuffs are the main sources of bacteria transmission to ready-to-eat food. This study aims to determine the genetic affinity of methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from cream pastries and workers, nasal of Shiraz city confectioneries. Methods: 30 MRSA strains (7 nasal carriers, 23 food isolates) were selected from the bank of bacteria at Shiraz medical faculty. To determine the genetic affinity of the isolates, RAPD-PCR technique was performed using OLP6, OLP11, and OLP13 primers. RAPD-PCR patterns were analyzed using the software GelJ. Results: By using primer OLP6 only 5 RAPD-PCR patterns were produced from DNA ampliqons of creamy pastry isolates and were not enough to compare the genetic affinity of all the isolates. Based on 100% similarity, OLP13 primer produced 20 different patterns with some bands in the range of 1 to 11, and the OLP11 primer produced 22 patterns with some bands from 3 to 11 bands. At closely and possibly genetically related levels, the isolates are categorized into (13-15) and (1-5) clusters. In general, all the isolates are classified into human and food isolates. Conclusions: There was no genetic affinity of MDSA isolates regarding human and food samples; but, a high percentage of close genetic relationship between the isolates increases the possibility of bacteria transfer from humans to pastries and food poisoning.

The effect of education of self-care behaviors on the quality of life and resilience of multiple sclerosis patients

BackgroundMultiple sclerosis (MS) is one of the most common causes of non-traumatic disability in young adults. Typically, doctors diagnose MS between the ages of 20 and 50. This study aims to determine the effect of educational intervention on self-care behaviors on MS patients’ quality of life and resilience in Shiraz, Iran.MethodsThis interventional study included 90 individuals, aged 15 to 50, who were members of the support association for MS patients in Shiraz city, Iran. The study employed a convenient sampling method. Patients were randomly assigned to two experimental and control groups, and the self-care educational program was conducted during six educational sessions. The quality of life and resilience of the patients were measured before and after the study. Information was collected by completing the questionnaires before and three months after the intervention. To analyze the data, SPSS 23 was used. To describe the data, frequency, percentage, mean, and standard deviation indicators were used, and for analysis, independent t-tests and paired t-tests were used.ResultsThis study examined a total of 90 MS patients. 50.4% of the people in the study were married, 40% of them had a high school diploma, and 78.5% were unemployed. The results of the t-test showed that there was a significant difference between all the components of self-care, quality of life, and resilience before and after the intervention (P < 0.05).ConclusionBy accepting the responsibility of self-care, patients would improve the inadequacies and disabilities resulting from the disease, use the power of self-care to solve problems, and improve their quality of life and resilience.

Students’ behaviour analysis based on correlating thermal comfort and spatial simulations; case study of a schoolyard in Shiraz City

The significant impact of outdoor school environments on student behaviour highlights the need to study how students interact with their surroundings. This has become a central focus in recent educational research, leading scholars to use various methods to gain insight into student movement behaviour. This research introduces a novel data-driven spatial gridding technique, employing thermal comfort and space syntax evaluation through ENVI-met and depthMapX software. It validates the extracted climatic and spatial heatmaps using real-time drone footage and Python programming to map and visualize student movement patterns. The findings from the Pearson correlation analysis in the Orange Software suggest that the correlated spatial-thermal heatmap better represents students’ actual behaviour with a high correlation coefficient of 0.84 (p = 0.84). Furthermore, this study sheds light on how students’ dynamic and static behaviours are linked to the schoolyard’s thermal and spatial characteristics. In conclusion, this research innovatively combines real-time monitoring with dual-simulations to analyze student movement behaviour, providing valuable insights into specific schoolyard dynamics.

Comparisons of postoperative outcomes of laparoscopic versus open surgery using inverse probability of treatment weighting analysis: an evidence from Iran

BackgroundColorectal cancer has created a significant burden worldwide, including in Iran. Open and laparoscopic surgery are important treatment methods for this disease. The aim of this study is to compare postoperative outcomes of laparoscopic versus open surgery in Iran, with a particular emphasis on controlling confounding factors.MethodsTo control confounding factors in between-group comparisons of observational studies, a method based on propensity scores was used. The current study was conducted on 916 patients with colorectal cancer in the city of Shiraz between the years 2011 to 2022. The required data regarding treatment outcomes, type of surgery, demographic characteristics, and clinical factors related to cancer was extracted from the Colorectal Cancer Research Center of Shiraz University of Medical Sciences. To control confounding factors, we used the Inverse Probability of Treatment Weighting (IPTW) as one of the analytical approaches based on Propensity Score analysis. After IPTW analysis, univariate logistic regression was used for treatment effect estimation. Stata 17 was used for statistical analysis.ResultsAfter controlling for 24 clinical and demographic covariates, negative post-operative outcomes were significantly lower in laparoscopic than open surgery. There were significant differences between the two groups of surgery in the percentages of death due to cancer (P < 0.01), recurrence (P < 0.01), and metastasis (P < 0.05). The treatment effect univariate logistic regression analysis indicated that laparoscopic surgery reduced the risk of negative postoperative outcomes including death due to cancer (OR = 0.411, P < 0.01), recurrence (OR = 0.343, P < 0.01) and metastasis (OR = 0.611, P < 0.05) compared to open surgery.ConclusionsIn terms of postoperative outcomes including cancer-related mortality, recurrence, and metastasis, the laparoscopic surgery outperformed open surgery. Therefore, further development of laparoscopic surgery can lead to better health outcomes for the population and optimize the utilization of healthcare resources.

Investigating the relationship between health literacy and preconceptual care components during the first 14 weeks of pregnancy: a cross-sectional study

Background and AimPreconceptual care aiming to improve health is influenced by various factors including health literacy. Considering the importance and necessity of high quality preconceptual care, this study aimed to determine the relationship between health literacy and receiving components of preconceptual care prior to pregnancy.MethodsThis cross-sectional study included 693 participants with pregnancies of less than 14 weeks gestation referred to health centers and gynecologists in Shiraz city, Iran. Multi-stage sampling was done from May 2021 to February 2022 in 18 comprehensive urban health centers and 20 gynecology offices via proportional allocation method. The data collection tool comprised a questionnaire consisting of 3 parts: (1) individual and fertility characteristics, (2) information related to the components of preconceptual care and (3) health literacy for Iranian adults. This was completed by individual participants via the self-reporting method.ResultsThe majority of participants were between 30 and 34 years old. They also identified as women with a university education and were predominantly unemployed. The mean health literacy of participants was 76.81%. Health literacy obtained the highest mean score in the dimension of ‘understanding’ and the lowest mean score in the dimension of ‘access’. The frequency of preconceptual counseling, folic acid supplement consumption, exercise, blood testing, dental visits, genetic counseling, Pap smear testing and rubella, diphtheria, and hepatitis vaccinations prior to pregnancy was 66.8%, 53.8%, 45.6%, 71.86%, 44.44%, 12%, 53.4%, 10.83%, respectively. Many (> 64%) received preconceptual care at specialist gynecology offices. Results demonstrated that health literacy had a statistically significant relationship with preconceptual care, folic acid consumption, exercise and dental care, (p < 0.001), along with blood testing and Pap smear testing (p < 0.05).ConclusionOverall, our results demonstrate that despite health literacy being optimal, uptakes of some components of preconceptual care are low. As such, it will be important to further raise awareness of the importance of preconceptual care for people prior to pregnancy as a priority in health promotion and education.

Biomonitoring of airborne microplastics and microrubbers in Shiraz, Iran, using lichens and moss.

Microplastics (MPs) and microrubbers (MRs) determined in lichens and mosses around Shiraz. In lichens, MPs mainly thin fibres up to 1 MP g-1; MRs were < 0.1 MP g-1. In mosses, abundances were similar but with a greater fraction of larger, non-fibrous particles. Larger MPs and MRs decreased in abundance with distance and elevation from Shiraz. Around Shiraz, the common moss, Grimmia critina, would be the most suitable biomonitor. Lichens and mosses have been employed as biomonitors of atmospheric particulate pollutants, like metals and industrial solids, for many decades. Here, we evaluated the potential of nine species of crustose and foliose lichens and a widely distributed moss (Grimmia critina) to act as biomonitors of airborne microplastics (MPs) and microrubbers (MRs). About 200 lichens and 40 mosses were sampled across different altitudinal transects in the vicinity of Shiraz City, southwest Iran, and MPs and MRs were quantified and characterised after sample peroxidation. In most species of lichen, MP and MR abundance overall was < 1g-1 and < 0.1g-1, respectively, and the majority of plastics were fibres of < 10 µm in diameter and < 1000 µm in length. Respective weight normalised abundances of MPs and MRs were similar in G. critina, but there were greater proportions of both larger (> 1000µm) and non-fibrous particles among the MPs. In both lichens and moss, there was a greater number of larger MPs and MRs at locations closest to and at the same elevation as Shiraz than at more distant and elevated locations, suggesting an inverse relationship between particle size and distance travelled. Among the lichens, members of the genus Acarospora, with their areolated form, appeared to act as the most suitable biomonitors for MPs and MRs. Overall, however, the wide distribution of the moss, G. crinita, and its ability to intercept and accumulate a broader range of sizes and shapes of MPs and MRs make this species a better choice, at least in the type of environment studied.

A Cone-Beam Computed Tomography-Based Evaluation of Root Dilaceration in Permanent Premolars: A Retrospective Study.

As a developmental disorder characterized by an abnormal bend and angle in the longitudinal axis of the tooth root, dilaceration can cause complications in routine dental procedures such as endodontics, orthodontics, and surgical treatments. The purpose of this study was to investigate the prevalence of dilaceration in maxillary and mandibular premolar teeth in a population of Shiraz city based on cone-beam computed tomography (CBCT). This is a retrospective cross-sectional study on 927 premolar teeth and 132 CBCT radiographs of patients obtained from four private radiology clinics in Shiraz (Iran). In this study, the presence, location, direction, and severity of dilaceration in premolar roots as well as its relationship with gender were investigated. Chi-square and Fisher tests were used to analyze the data. The results showed that 17% of the studied 927 teeth had dilaceration. The prevalence of dilaceration was significantly higher in women than in men (20.3% vs. 13.6%, p= 0.005). The dilaceration rates were significantly higher in the mandibular first and second premolar teeth (31.6% and 26%, p= 0.002) than in the other teeth. In addition, the highest prevalence was in the distal direction with mild severity in the apical third of the root (p< 0.001). According to the results of this study, the prevalence of dilaceration was relatively high in mandibular premolar teeth especially in women.

The Effect of Mothers Education on Reduction the Aggression Behavior Among Computer Game User Students

Background: Nowadays, children and teenagers easily access computer games while parents are unaware of the dangers posed by excessive use of these games. The present study investigated the effect of educational intervention based on the theory of planned behavior (TPB) on primary school boys’ aggression levels. Methods: This research was a randomized controlled trial. The sample size was determined to be 180 considering a confidence interval of 95% and test power of 90% (group 1=90, group 2=90). The sampling environment was a multi-stage cluster with four primary schools from two education districts in Shiraz City, Iran in 2013. The participants were evaluated once before the intervention and then one week and one month after the educational intervention. We used the aggression checklist (12 items) and a researcher-made questionnaire according to TPB theory, which has suitable validity and reliability. The data were analyzed using SPSS software, version 19. Results: There was no difference between the two groups before the intervention. After the education program, the 4 constructs of TPB, including attitude, perceived behavioral control, behavioral intentions, and behavior, increased in the intervention group compared to the control group (P&lt;0.001). Conclusion: According to the findings, it seems that the educational intervention on mothers based on TPB leads to the reduction of aggressive behavior of elementary school students.

Applying analytic hierarchy process for site selection of a recreational-educational children complex in Shiraz City, Iran

The development of educational-recreational complexes for children has a significant impact on their cognitive growth and behaviour. Proper site selection is essential to ensure the success of such projects. This paper aims to identify the best location for a children’s educational-recreational complex in Shiraz, Iran. The study used a descriptive-comparative and survey method to determine effective criteria for site selection. A questionnaire was administered to experts in architecture, urban design, and planning to identify appropriate sites. The Analytic Hierarchy Process (AHP) method was then employed to select the best location. The hierarchical model included three levels: goal (educational-recreational site selection), criteria (natural potential, accessibility, land size, neighbourhood and social context, expansibility, appropriate land use (the neighbourhood between proposed and master plan land use)), and three alternative sites. The results showed that a site located near residential areas, green spaces, and natural elements is suitable for the development of an educational-recreational complex for children. The study recommends the use of the SWOT (strength, weaknesses, opportunities and threats) - AHP method for site selection in children’s complexes. The paper highlights the need for a reliability test or table/figure to support the research findings.

Investigating the psychometric properties of the persian version of the psychological inventory of criminal thinking styles

Introduction: The psychological inventory of criminal thinking styles (PICTS) plays a significant role in the diagnosis and evaluation of criminal thinking styles. It emphasizes the importance of cognition, particularly in the commission and perpetuation of crimes in the field of psychology. Aim: The present study was conducted with the aim of investigating the persian version of the PICTS in prisoners. Method: The current research was a descriptive-applied study of the psychometric type. The statistical population consisted of prisoners in Shiraz city in 2022. The statistical sample included 519 prisoners from Adel Abad prison in Shiraz who were selected through purposive sampling. They completed the PICTS. Data analysis was conducted using Cronbach's alpha coefficient, Pearson's correlation coefficient, and confirmatory factor analysis in SPSS and AMOS version 22 software. Results: The results of the confirmatory factor analysis supported the eight criminal thinking styles model and the criminal thinking hierarchy model of the PICTS, and the fit indices were favorable. The Cronbach's alpha coefficient for overall criminal thinking was 0.91, and for proactive and reactive thinking styles, it was 0.89 and 0.79, respectively. Additionally, the Cronbach's alpha coefficient for the eight criminal thinking styles ranged between 0.61 and 0.81, and the test-retest correlation coefficient was between 0.63 and 0.86. Conclusion: The reliability and validity of the persian version of the PICTS has been confirmed. It is recommended that social workers and professionals in the field of criminal psychology use this questionnaire to predict the commission and perpetuation of crimes.

The Effect of an Educational Intervention on Breast Cancer Screening of Rural Women: Application of the Theory of Planned Behavior.

Early diagnosis of breast cancer is a key factor affecting patient survival, so screening can reduce the burden of this disease. The present study aimed to investigate the effect of education based on the theory of planned behavior (TPB) on breast cancer screening in rural women. In this quasi-experimental study, 480 women referring to the health care centers in the cities of Fasa and Shiraz were divided into two groups, intervention (n = 240) and control (n = 240), using cluster random sampling method, in 2021-2022. We randomly selected two health care centers in Shiraz and Fasa and invited them to participate in the study. The demographic information questionnaire and a researcher-made questionnaire based on the TPB were used to collect the data. The intervention included 50-minute sessions on topics such as breast cancer basics, screening methods, barriers to mammography, and the role of peer groups. Data were collected before and 4months after the intervention. The results showed no difference between the two groups in awareness, attitude, perceived behavioral control, subjective norms, behavioral intention, and breast cancer screening performance before the intervention. Four months after the intervention, a significant increase was found in the intervention group in awareness (7.46 ± 1.50 to 18.54 ± 1.20), attitude (28.55 ± 4.62 to 58.69 ± 4.35), perceived behavioral control (22.52 ± 3.32 to 40.88 ± 3.84), and subjective norms (20.37 ± 3.34 to 21.99 ± 3.38). Instead, no significant difference in the mentioned constructs (P < 0.05) was observed in the control group. This study demonstrated that TPB-based education enhanced awareness, attitude, perceived behavioral control, subjective norms, and behavioral intention towards breast cancer screening. The TPB empowers women in rural communities to prioritize their health and seek timely breast cancer screening. Continued efforts and improved access to screening services are crucial for improved outcomes.

Assessment of Load Manual Lifting among Shelf-Stoking Workers in Chain Stores: A Cross-Sectional Study.

In Iranian stores, shelf workers, in addition to shelf-stocking, perform diverse tasks, such as working as a cashier, cleaning, barcode reading, labeling goods, and entering the price with the portable data terminal (PDT). Therefore, this study aimed to investigate the prevalence of work-related musculoskeletal symptoms (WMSs) and assess load manual lifting among shelf-stoking workers. This cross-sectional study was conducted among 101 shelf-stoking workers (60 males and 41 females) in chain stores at Shiraz city, Iran. The subjects were selected by cluster sampling from chain stores in Shiraz city, namely Refah, Canbo, Soroush, and Tirazis. Then, the required number of samples was selected and entered into the study from each cluster in proportion. The Persian version of the Nordic Musculoskeletal Questionnaire and the National Institute of Occupational Safety and Health-variable lifting index method were used to collect the required data. Data were analyzed by SPSS software version 22 using the Mann-Whitney U test, Spearman's correlation coefficient, and linear regression. Ankles/feet, lower back, and knees had the highest prevalence of WMSs among the participants. About 70.3% of workers had a VLI higher than 1. There was an association between gender and VLI. The VLI was higher in males than females. The study's findings revealed that the medians of the VLI were significantly different among participants with/without upper back symptoms during 12 months prior to the study and among participants with/without lower back symptoms during 7 days prior to the study. According to the linear regression analysis, gender and lower back symptoms during 7 days prior to the study remained in the model and were associated with the VLI. The findings revealed that the back region of the shelf-stoking workers is prone to work-related musculoskeletal disorders. In addition, based on the results, gender and lower back symptoms during the 7 days prior to the study were predicting variables for VLI. This study provides an overview of pain/discomfort and postural load in shelf-stoking workers. Since the principles of ergonomics for the placement and layout of shelves are the same in all stores, the findings of the present study can be used in other stores.
