In this article, a novel bi-objective integer model is presented to integrate reliability and intra-cell layout in designing a cellular manufacturing system (CMS). Minimising the total costs (e.g. inter and intra-cell material handling, machine overhead and operation, and setting up routes) is the first objective with considering operation time, operation sequence, intra-cell layout, alternative process routing, routes selection, machines capacity, parts demand and parts movements in batches. Maximising the processing routes reliability is the second objective. The presented model is capable of modelling different failure characteristics including a decreasing, increasing, or constant value for machine failure rate. An illustrative example is solved to represent the capability of the presented model using theε-constraint method in order to demonstrate the conflict between the maximum value of the system reliability and the total costs of the system. Next, a multi-objective imperialist competitive algorithm (MOICA) is employed to find near-optimal solutions for medium- and large-sized test problems. Also, the efficiency of the proposed MOICA is revealed by comparison with the performance of a non-dominated sorting genetic algorithm (NSGA-II). The computational results demonstrate that the performance of the proposed MOICA is superior to the NSGA-II. Furthermore, a real-world case study is conducted to validate the proposed model.

- Abstract
Introduction: Opioid overprescription after colorectal surgery can lead to adverse events, persistent opioid use, and diversion of unused pills. This study aims to assess the extent to which opioids prescribed at discharge after elective colorectal surgery are consumed by patients., Methods: This prospective cohort study included adult patients (≥ 18 yo) undergoing elective colorectal surgery at two academic hospitals in Montreal, Canada. Patients completed preoperative questionnaires and data concerning demographics, surgical details, and perioperative care characteristics (including discharge prescriptions) were extracted from electronic medical records. Self-reported opioid consumption was assessed weekly up to 1-month post-discharge. The total number of opioid pills prescribed and consumed after discharge were compared using the Wilcoxon signed-rank test. Negative binomial regression was used to identify predictors of opioid consumption., Results: We analyzed 344 patients (58 ± 15 years, 47% female, 65% laparoscopic, 31% rectal resection, median hospital stay 3 days [IQR 1-5], 18% same-day discharge). Most patients received a TAP block (67%). Analgesia prescription at discharge included acetaminophen (92%), NSAIDs (38%), and opioids (92%). The quantity of opioids prescribed at discharge (median 13 pills [IQR 7-20]) was significantly higher than patient-reported consumption at one month (median 0 pills [IQR 0-7]) (p < 0.001). Overall, 51% of patients did not consume any opioids post-discharge, and 63% of the prescribed pills were not used. Increased opioid consumption was associated with younger age (IRR 0.99 [95%CI 0.98-0.99]), higher preoperative anxiety (1.02 [95%CI 1.00-1.04]), rectal resections (IRR 1.45 [95%CI 1.09-1.94]), and number of pills prescribed (1.02 [95%CI 1.01-1.03])., Conclusion: A considerable number of opioid pills prescribed at discharge after elective colorectal surgery are left unused by patients. Certain patient and care characteristics were associated with increased opioid consumption. Our findings indicate that post-discharge analgesia with minimal or no opioids may be feasible and warrants further investigation., (© 2024.

- Abstract
Background: This study aims to investigate international measures for pandemic control in the workplace based on guidelines from international organizations to learn from their experiences., Methods: We conducted a qualitative study using content analysis. The search method involved reviewing published guidelines on preventing and responding to the COVID-19 pandemic in workplaces. After the screening process, ten guidelines were included in the content analysis. During the analysis, 200 meaning codes, 49 subcategories, and eleven categories were identified. Trustworthiness criteria were utilized to ensure the accuracy and strength of the findings., Results: Eleven categories of international content during the COVID-19 pandemic were legal requirements and duties of employees and employers, structural and program changes, risk assessment, risk communication, information and training, internal and external consultation and cooperation, provision of facilities and tools for workplace hygiene, special conditions, special groups, closing and reopening workplaces, reducing contact and exposure and mental health., Conclusions: Protecting employees during a pandemic requires a multifaceted approach and strong advocacy. The operational plan for pandemic control should be developed based on the level of risk, with support tailored to employees' conditions and needs. Cooperation among international organizations is essential to develop a standardized plan and issue comprehensive guidelines in response to health emergencies with a global perspective and local implementation, drawing from the lessons learned during the COVID-19 pandemic., (© 2024.

- Abstract
We used an Intervention Mapping Approach (IMA) to derive multi-level HIV prevention strategies aiming to develop an HIV prevention intervention program among female sex workers (FSWs). We also aimed at pilot testing the effects of the IMA-based "HIV Prevention and Awareness Program (HIV-PAP)" on safe sex behaviors and its determinants among FSWs in Tabriz, Iran. To develop HIV-PAP, we conducted the six-step process of IMA. At Step 1, in a cross-sectional study, 140 FSWs were face-to-face interviewed. At Step 2, the program matrix was provided based on the importance and variability for identifying priority factors. At Steps 3 and 4, the methods and strategies for behavioral change were selected, and the HIV-PAP program components and materials were developed. At Steps 5 and 6, evaluation (as a pilot testing with Static-Group Comparison design) was conducted applying a pre-experimental study, in which 30 FSWs were assigned to intervention (n = 15) and control (n = 15) groups. The intervention group participated in a two-month long program, and one month later, the initial questionnaires were completed by both groups. The respondents (M age: 33.4 years, SD: 9.7) acquired low score (less than 50%) in negotiating for condom use (49.8%) only, and moderate scores (50-65%) in perceived social support (61.6%) and knowledge (60.5%). Adjusted for other variables, the factors (R
2 = 32.0%) associated with safe sex behaviors among FSWs were predisposing factors [self-efficacy (β = 0.331), perceived norms (β = 0.945), and perceived barriers (β = 0.258)], condom use negotiation (β = 1.386), and environmental factors (β = 0.333). Our IM-based framework had an adequate fit index (χ2 = 130.8, CFI = 0.78). Looking for inter-group comparison after intervention, we found significant mean difference (MD) for knowledge (MD: 2.18; 95% Confidence Interval (CI) - .38 to 4.74, p < 0.05), self-efficacy to use condom (MD: 6.71; 95% CI - 1.85 to 9.29, p < 0.05), perceived risk (MD: 2.03; 95% CI 0.58, to 3.49, p < 0.05), perceived social support (MD: 4.64; 95% CI - 5.37 to 11.31, p < 0.01), and safe sexual behaviors (MD: 7.75; 95% CI - 4.19 to 9.71, p < 0.05). The HIV-PAP showed effectiveness in promoting safe sexual behaviors and their determinants among FSWs. Healthcare providers should better understand the determinants of safe sexual behaviors among FSWs in the settings with legal prohibitions for sex work. In such communities, they should try to either develop or adapt such stage-specific interventions, within which promoting the above-mentioned factors is the core priorities of the program., (© 2024.

- Abstract
Background: Menstruation is a natural occurrence that women experience during their reproductive years and may encounter many years throughout their lifespan. Many adolescent females lack accurate knowledge about menstruation, so they may face issues from receiving incorrect information from unreliable sources. Our study aimed to investigate the practices and beliefs surrounding menstruation among Iranian adolescent females., Methods: This qualitative study was conducted using conventional content analysis. A purposeful sampling method was used to select 18 adolescent females from secondary and high schools located in the three regions of Neyshabur City-Iran. Data were collected through in-depth, semi-structured interviews., Results: Three main themes were extracted, consisting of lifestyle and related beliefs, lake of support, and awareness and information., Conclusions: misconceptions and wrong behaviors during menstruation indicate that the lake of knowledge an traditional factors influence adolescent girls' health. The study provides the basis for intervention planning in this regard and different levels (individual, intrapersonal, health systems, and community)., (© 2024. The Author(s).)

- Abstract
Background: Psammomatoid ossifying fibroma (POF) is a rare craniofacial neoplasm, primarily affecting the maxillofacial region, and typically observed in adolescents and young adults. This case report presents a unique occurrence of POF in a 50-year-old male, defying the conventional age range and exhibiting an unusual anatomical location within the frontal sinus., Case: A 50-year-old male with a prior history of cecal adenocarcinoma and colectomy presented with left eye proptosis and new-onset headaches. Imaging revealed a well-defined calcified mass in the left frontal sinus, leading to a diagnosis of POF. Open surgical resection was performed to remove the tumor, and histopathological evaluation confirmed its diagnosis as psammomatoid ossifying fibroma. The patient exhibited no postoperative complications or signs of recurrence., Conclusion: This case underscores the diverse clinical presentations and diagnostic challenges associated with POF, emphasizing the importance of accurate diagnosis and multidisciplinary collaboration. Further research is needed to explore the genetic underpinnings and optimal management strategies for this intriguing condition., (© 2024 The Authors.

- Abstract
Differences in corticocerebral structure and function between males and females and their effects on behavior and the prevalence of various neuropsychiatric disorders have been considered as a fundamental topic in various fields of neuroscience. Recent studies on working memory (WM) reported the impact of sex on brain connectivity patterns, which reflect the important role of functional connectivity in the sex topic. Working memory, one of the most important cognitive tasks performed by regions of the PFC, can provide evidence regarding the presence of a difference between males and females. The present study aimed to assess sex differences in brain functional connectivity during working memory-related tasks by using functional near-infrared spectroscopy (fNIRS). In this regard, nine males and nine females completed a dual n-back working memory task with two target inputs of color and location stimuli in three difficulty levels ( n = 0, 1, 2). Functional connectivity matrices were extracted for each subject for each memory load level. Females made less errors than males while spending more time performing the task for all workload levels except in 0-back related to the color stimulus, where the reaction time of females was shorter than males. The results of functional connectivity reveal the inverse behavior of two hemispheres at different memory workload levels between males and females. In the left hemisphere, males exhibited stronger connectivity compared to the females, while stronger connectivity was observed in the females' right hemisphere. Furthermore, an inverse trend was detected in the channel pairs with significant connectivity in the right hemisphere of males (falling) and females (rising) by enhancing working memory load level. Considering both behavioral and functional results for two sexes demonstrated a better performance in females due to the more effective use of the brain. The results indicate that sex affects functional connectivity between different areas in both hemispheres of the brain during cognitive tasks of varying difficulty levels although the general impression is that spatial capabilities are considered as a performance of the brain's right hemisphere. These results reinforce the presence of a sex effect in the functional imaging studies of hemodynamic function and emphasize the importance of evaluating brain network connectivity for achieving a better scientific understanding of sex differences., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Shirzadi, Dadgostar, Einalou, Erdoğan and Akin.)

- Abstract
Introduction: Workplaces are high-risk environments for epidemic transmission, and the COVID-19 pandemic has highlighted the significant impacts that health emergencies can have on both the healthcare system and the economy. This study presents executive and hierarchical models for participatory response to health emergencies in the workplace, with a focus on COVID-19., Methods: The study was conducted in three phases. Content analysis of interviews with 101 stakeholders and national documents was used to identify key themes and dimensions for an executive model. A focus group discussion and review of international documents were then used to refine and expand the executive and hierarchical models. The alignment and trustworthiness of the final models, as well as feedback, were gathered from 117 informants working in various workplaces., Results: The executive model highlighted that context understanding, management commitment, and participation play critical roles in developing tailored prevention and response plans, and adequate support is necessary for successful plan implementation. Monitoring and review processes should be established to ensure proper functioning. The hierarchical model emphasizes the need for collaborative efforts from various stakeholders to effectively implement pandemic prevention and participatory response plans., Conclusion: Overall, the executive and hierarchical participatory models presented in this study provide a framework for effectively controlling pandemics and other health emergencies in the workplace, enhancing both health resilience and the sustainability of economic activities., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.

- Abstract
Background: Chondrosarcomas are an exceedingly rare form of cancer, impacting only a few individuals per million. Among chondrosarcomas, a small fraction belongs to the mesenchymal sub-type. Furthermore, only one-third of mesenchymal chondrosarcomas manifest in extraskeletal locations., Case: A 38-year-old woman was referred by a midwife after experiencing pain in the right upper quadrant of her right breast for 2 months. The mass had been palpable for 1 week before the initial assessment. According to radiological evaluations, the tumor is outside breast tissue and not connected to the bones. Hence, a biopsy of the mass is done. The biphasic morphology of the tumor during pathological evaluation, in addition to immunohistochemistry testing, confirms the diagnosis of extraskeletal mesenchymal chondrosarcoma (EMCS). Finally, the mass was surgically removed, and 6 months of chemotherapy were administered to the patient., Conclusion: Given the tumor's rarity and the lack of established guidelines, diagnosing EMCS can be challenging and prone to errors. As such, meticulous sampling, along with precise pathological and imaging investigations, is imperative to accurately establish the diagnosis of these tumors., (© 2023 The Authors.

- Abstract
Background: Proper elucidation of medication non-adherence reasoning especially in older adults might pave the way for an auspicious therapeutic outcome. The main aim of this study was to develop and psychometrically test the Medications Non-adherence Reasoning (MedNARS) questionnaire for application in research and probably practice settings., Methods: A mixed methods design was utilized to develop the MedNARS. The item pool was mainly generated based on a qualitative query and literature review. The expert panel approved version of the MedNARS was psychometrically assessed on a convenience sample of 220 older patients with chronic disease. The internal consistency, test-retest reliability, content and face validity of the scale were appraised and its construct validity was assed using exploratory and confirmatory factor analyses., Results: A nine-item version of the MedNARS was drafted based on the classical item analysis procedures and its estimated internal consistency measure of the Cronbach's alpha (0.85) and test-retest reliability (0.96) were in the vicinity of acceptable range. The exploratory factor analysis (EFA) output revealed a unidimensional structure for the MedNARS and the conducted confirmatory factor analysis (CFA) indicated an acceptable data fit for the extracted one-factor model. The goodness of fit indices were as the followings: χ
2 /df=1.63(90% CI: 0.02 to 0.11), root mean squared error of approximation (RMSEA)=(0.07), comparative fit index (CFI)=0.95, Tucker-Lewis index (TLI)=0.93 and standardized root mean squared residual (SRMSR)=(0.05)., Conclusion: The study findings were indicative of MedNARS's applicability and feasibility for use in assessment of medication non-adherence reasoning among the elderly patients with chronic diseases. The MedNARS as a brief and elder-friendly instrument can be applied both in research and practice settings to enhance efficiency, safety, and health outcomes of the therapeutic recommendations., Competing Interests: Hamid Allahverdipour is the editor-In-chief, Abdolreza Shaghaghi and Mohammad Asghari-Jafarabadi are also associate editors of the Health Promotion Perspectives.

- Abstract
Background: Scorpion envenomation is associated with several complications. One of the most serious complications is the cardiac involvement in the form of myocarditis that remains the main reason for mortalities associated with scorpion envenomation. The present review aims to elucidate clinical and paraclinical findings associated with scorpion-related myocarditis, and to explore different management strategies and subsequent outcomes., Methods: We searched PubMed, Web of Science, Scopus, and Google Scholar for articles related to keywords of myocarditis associated with scorpion envenomation up to May 1, 2022. Each article was carefully reviewed by two independent researchers. In case of disagreement for inclusion, we sought a third researcher opinion., Results: A total of 703 cases from 30 case reports and 34 case series were included in our review. Myocarditis associated with scorpion envenomation was usually reported in children presenting with cardiopulmonary symptoms including pulmonary edema (60.7%) and shock or hypotension (45.8%). The most common ECG findings are sinus tachycardia (82%) followed by ST-T changes (64.6%). The management typically included inotropes (especially dobutamine), prazosin, diuretics, nitroglycerine and digoxin, when indicated. Mechanical ventilation was required in 36.7% of the patients. Mortality in confirmed scorpion-related myocarditis cases is estimated at 7.3%. Almost all survived cases showed rapid recovery and improvement in the left ventricular function., Conclusion: Even though myocarditis associated with scorpion envenomation is rare, it remains a serious and in some of cases a fatal consequence of scorpion sting. In case of relative presentations, particularly in envenomed children, diagnosis of myocarditis should be considered. Early screening using serial cardiac markers and echocardiography can guide the treatment. Prompt treatment that focuses on cardiogenic shock and pulmonary edema usually results in a favorable outcome., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Fereidooni et al.

- Abstract
Introduction: Pneumatic retinopexy (PnR) was proposed as an alternative to pars plana vitrectomy (PPV) in certain circumstances. PnR is an outpatient procedure and more cost-effective. However, its benefits should be judged alongside its success rate and adverse events. Herein, we compare the efficacy and safety of PnR and PPV for rhegmatogenous retinal detachment (RRD) repair., Methods: We searched the PubMed, Scopus, EMBASE, Web of Science, Cochrane, and Google Scholar databases. Observational and interventional studies comparing the efficacy and safety of PnR and PPV were included. The outcomes were the success rate of the treatment, improvement in visual acuity, and adverse event rates. Subgroup analysis was performed based on the lens and macula status. Eleven articles were eligible to enter our study; these consisted of 11,346 patients with a mean age of 74.1., Results: PnR was superior to PPV in terms of retinal displacement, photoreceptor integrity, visual function, and vertical metamorphopsia scores. In the meta-analysis, PPV showed higher a reattachment rate than PnR (OR = 3.39, 95% CI 2.25-5.11). Subgroup analysis showed that the advantage of PPV over PnR was more pronounced in studies with fewer phakic eyes, more macula-on patients, and in cases with primary PnR failure. While PnR patients had better pre-op (SMD = - 0.58, 95% CI = - 1.16 to 0.00) and post-op (SMD = - 0.45, 95% CI = - 0.60 to - 0.30) LogMAR, the improvement in visual acuity after surgery was higher in PPV patients (SMD = 0.49, 95% CI = - 0.15 to 1.13)., Conclusion: The success rate of PnR was higher in studies published after 2015 compared to previous studies (82% vs. 59%). Cataract formation and surgery were significantly higher in the PPV arm, while the occurrence of new retinal tears was more frequent in the PnR group. PnR can be used as the primary procedure for RRD repair in selected cases. However, we propose some modifications to the PIVOT criteria, e.g., the exclusion of cases presenting with several risk factors of poor outcomes., (© 2023. The Author(s).)

- Abstract
Background: Type 2 diabetes mellitus (T2DM) is one of the most important risk factors for cardiovascular diseases, with a high economic burden on health care systems. Since gender and residency can affect people's lifestyle and health behaviors, this study was conducted to investigate the prevalence of T2DM and its determinants by gender and residency., Methods: A secondary analysis study was conducted on the survey data of the IraPEN (Iran's Package of Essential Non-Communicable Disease) pilot program conducted in 2017 in Naghadeh County, Iran. Data of 3,691 participants aged 30-70 years from rural and urban areas of the County were included into data analysis process. Sociodemographic factors, anthropometric measurements, and cardiovascular risk factors related to T2DM were assessed., Results: The overall prevalence of T2DM within the population was 13.8%, which was significantly higher among women (15.5%) than men (11.8%), and non-significantly higher in urban (14.5%) areas than rural (12.3%) areas. In both genders, age (male: OR 1.01, 95% CI: 1.00-1.03; P = 0.012; female: OR 1.03, 95% CI: 1.02-1.04; P<0.001), blood pressure (male: OR 1.77, 95% CI: 1.13-2.79; P = 0.013; female: OR 2.86, 95% CI: 2.12-3.85; P<0.001), and blood triglycerides (male: OR 1.46, 95% CI: 1.01-2.11; P = 0.04; female: OR 1.34, 95% CI: 1.02-1.77; P = 0.035) had a significant relationship with the chance of developing T2DM. Among women, a significant relationship was found between abdominal obesity (OR 1.68, 95% CI: 1.17-2.40; P = 0.004) and the chance of developing T2DM. Age (rural: OR 1.03, 95% CI: 1.01-1.04; P<0.001; urban: OR 1.02, 95% CI: 1.01-1.04; P<0.001), blood pressure (rural: OR 3.14, 95% CI: 2.0-4.93; P<0.001; urban: OR 2.23, 95% CI: 1.66-3; P<0.001), and abdominal obesity (rural: OR 2.34, 95% CI: 1.41-3.87; P = 0.001; urban: OR 1.46, 95% CI: 1.06-2.01; P = 0.019), in both rural and urban areas, blood cholesterol (OR 1.59, 95% CI: 1.07-2.37; P = 0.02) in rural areas, and blood triglycerides (OR 1.51, 95% CI: 1.16-1.98; P = 0.002) in urban areas were significant predictors of T2DM., Conclusion: Given the higher prevalence of T2DM among females, risk reduction strategies at the community level should be more targeted at women. The higher prevalence of T2DM risk factors among the urban population is a wake-up call for policymakers to pay more attention to the consequences of unhealthy and sedentary lifestyles within urban communities. Future actions should be focused on appropriate timely action plans for the prevention and control of T2DM from early years of life., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Ghassab-Abdollahi et al.

- Abstract
Background: Model for end-stage liver disease (MELD) is currently used for liver transplantation (LT) allocation, however, it is not a sufficient criterion., Objective: This current study aims to perform a hybrid neural network analysis of different data, make a decision tree and finally design a decision support system for improving LT prioritization., Material and Methods: In this cohort follow-up-based study, baseline characteristics of 1947 adult patients, who were candidates for LT in Shiraz Organ Transplant Center, Iran, were assessed and followed for two years and those who died before LT due to the end-stage liver disease were considered as dead cases, while others considered as alive cases. A well-organized checklist was filled for each patient. Analysis of the data was performed using artificial neural networks (ANN) and support vector machines (SVM). Finally, a decision tree was illustrated and a user friendly decision support system was designed to assist physicians in LT prioritization., Results: Between all MELD types, MELD-Na was a stronger determinant of LT candidates' survival. Both ANN and SVM showed that besides MELD-Na, age and ALP (alkaline phosphatase) are the most important factors, resulting in death in LT candidates. It was cleared that MELD-Na <23, age <53 and ALP <257 IU/L were the best predictors of survival in LT candidates. An applicable decision support system was designed in this study using the above three factors., Conclusion: Therefore, Meld-Na, age and ALP should be used for LT allocation. The presented decision support system in this study will be helpful in LT prioritization by LT allocators., Competing Interests: None, (Copyright: © Journal of Biomedical Physics and Engineering.)

- Abstract
Background: Cardiovascular Diseases (CVDs) are one of the major causes of hospitalization and mortality worldwide. Strengthening perceived social support and quality of life can reduce these problems. This study aimed to describe the role of perceived social support on cardiovascular patients' quality of life., Methods: This cross-sectional study was conducted from September 2020 to February 2021. We selected 150 cardiovascular patients through convenience sampling. The questionnaires included: the Persian version of the WHOQOL-BREF, Perceived Social Support, and demographic variables. Hierarchical linear regression was used to explore the association between perceived social support and quality of life. Data were analyzed by SPSS version 21.0 software. A P-value less than 0.05 is considered statistically significant., Results: The demographic variables could predict 12.2% of the variance of quality of life in the first step. In the second step, after adjusting control variables and dimensions of social support, the predictability increased to 29% of the variance with the addition of variables. All dimensions of social support, excluding tangible assets support, were significant predictors of quality of life and monthly income status. Self-esteem support (β= 0.387) was the strongest predictor of quality of life in cardiovascular patients., Conclusions: Patients with higher perceived social support have a better quality of life than the other patients. Perceived social support is one of the strategies that can be utilized to improve quality of life and overcome disease in cardiovascular patients., (© 2022 Abdi Khalil M., et al.)

- Abstract
Background: Tuberculosis (TB) remains an infectious disease with a high prevalence worldwide and represents a major public health concern. It is known that TB causes a hyper-coagulable state due to its infective nature. Thus, patients are prone to higher incidence rates of venous thromboembolism (VTE) in comparison with the general population. Although there are many risk assessment models (RAMs) that estimate the risk of VTE incidence in the general population, none have been proven to show significant prognostic value in early and accurate VTE prediction among TB patients. This study aims to investigate the accuracy of general RAMs in prediction of VTE incidence in the population of TB-positive patients., Methods: The following survey is a retrospective study among patients afflicted with TB, in whom VTE had occurred either during or at the onset of admission. A total number of 865 smear-positive TB cases were recorded in hospital in a 7-year timespan, among which a total sum of 37 patients (67.6% males, age: 56.19 ± 20 years) experienced at least one episode of thromboembolic incidence. We nominated Padua and Geneva RAMs and calculated the scores with regard to their inpatient hospital records., Results: Of 865 adult hospitalized smear-positive TB patients, 37 patients happened to develop VTE in the course of infection, after excluding the unacceptable data. The incidence of VTE was calculated at 4.27%. Of all VTEs, 73% turned out to be deep venous thromboembolism (DVT), 18.9% were pulmonary thromboembolism (PTE), and 8.1% of patients developed both DVT and PTE during the course of disease. Among all cases, 32.4% revealed Geneva score equivalent or >3. It conveys the meaning that these patients were at greater risk for VTE development and were indicated to receive prophylactic medication. Similarly, Padua model was capable of predicting 29.7% cases scoring >4, which is alarming for elevated VTE probability. 21.6% of TB patients, who had developed VTE during the course of their disease eventually passed away., Conclusion: Our statistics show minimal positive predictive value for Padua and Geneva RAMs, which are seemingly in sharp contrast with the excellent validation of these models verified by numerous surveys in general population. This fact could be attributable to failing to consider TB, or in general chronic infections, as independent indicators of VTE incidence. These findings indicate the need for revising the presenting RAMs or establishing a separate RAM for VTE prediction in TB patients, resembling the VTE risk assessment model for cancer patients., Competing Interests: None

- Abstract
Background: Leptospirosis is known as a public health problem in developing and developed countries. The aim of this study was to investigate the incidence and geographical distribution of leptospirosis using the Geographic Information System (GIS) and to predict its incidence in Iran in 2021. Methods: This was a descriptive analytical study. Information on leptospirosis was obtained from the Center for Communicable Diseases Control during 2009-2015. In the next step, The ArcGIS 9.3 was used to prepare geographic maps of the disease incidence and frequency. Therefore, using the Raster Calculator tool, the disease prediction map was drawn. Results: The results showed that the highest incidence of leptospirosis during 2009-2015 was observed in Gilan, Mazandaran, and Golestan provinces, respectively. The incidence of the disease had an increasing trend from 2013 to 2015. Based on the results of the modeling in Iran, the provinces of Gilan, Mazandaran, and Golestan, with 72.18%, 8.54%, and 4.95% of their area, respectively, have the largest areas at a high-risk for leptospirosis in the coming years. Conclusion: The prevalence of leptospirosis is affected by geographical and climatic conditions of every region; thus, the incidence of the disease is higher in the provinces located at the Caspian coastal side and in some regions in Semnan province. Hence, if health authorities pay more attention to developing health plans to prevent the disease, the risk of disease in these areas will be reduced in the future., (© 2021 Iran University of Medical Sciences.)

Background: Pertussis is a respiratory tract infection caused by Bordetella pertussis, which causes inflammation of the lungs and respiratory tract. The purpose of this study was to investigate the incidence and geographical distribution of pertussis using the geographic information system (GIS) and to predict its incidence in Iran in 2021. Methods: This was a descriptive analytical study. Information on pertussis was obtained from the Center for Communicable Diseases Control during 2009-2015. In the next step, the ArcGIS 9.3 was used to prepare geographic maps of the disease incidence and frequency. Therefore, the disease prediction map was drawn. using the Raster Calculator tool. Results: The results showed that the highest incidence of pertussis during 2009-2015 was in Zanjan, Qom, Mazandaran, and Qazvin provinces. The incidence of pertussis in Iran increased from 0.74 in 2009 to 1.53 in 2015. Based on the modeling results for Iran, Qom, Mazandaran, Tehran, Qazvin, and Zanjan provinces, with 76.76%, 73.69%, 66.32%, 30.94% and 24.18% of their areas (Km2), are at high risk for pertussis in the coming years, respectively. Conclusion: The incidence of the disease has been increasing in recent years, indicating the emergence of the disease in Iran. The modeling maps show that the Iranian provinces of Qom, Tehran, Zanjan, and Qazvin are at risk of the disease incidence in the coming years, indicating the need for planning, appropriate interventions and more precise implementation of the vaccination program against the disease., (© 2021 Iran University of Medical Sciences.)

- Abstract
A novel periodical mixed-integer mathematical model in the field of fresh agri-food product's distribution (tomato product for instance) is developed in this paper. Green topics and two significant features of fresh agricultural products, namely freshness and ripeness, are added to the inventory routing problem (IRP) with simultaneous pickup and delivery for perishable products. The objective function tends to optimize the system total interest. In this model, traditional costs such as transportation and holding costs are considered besides up-to-date points such as expired products and customer's dissatisfaction costs. To compute the customer's dissatisfaction costs, the level of deviation from ideal quality should be measured to specify the biological postharvest behavior of fresh products. To determine the fair pricing, the patterns of quality decay have been applied. Considering the environmental effects and recycling requirements of expired crops, the reverse logistics notion has been applied to collect and reuse the wasted products. The level of greenhouse gas (GHG) emission has been controlled to reduce the harmful impressions of this gas and protect the environment. In the optimization procedure, the system total costs are developed by assuming fuzzy quality levels and fuzzy holding costs. Also, a bipolar approach has been applied for fuzzy programming. Finally, a numerical example besides sensitivity analysis and managerial insights is presented. Results show that remarking fuzzy parameters lead to lower profit and different routing and transmission. Also, applying less pollutant vehicles and increasing plant's delivery levels can be noted to reach a green environment and higher level of profit., (© 2021.

- Abstract
Background: Categorizing different injury patterns of the talus, describing demographic data, mechanisms of injury and associated fractures are important issues in orthopedic trauma surgeries. Injuries of the talus require careful attention with appropriate treatment approaches in order to reduce possible complications., Methods: In a cross-sectional study, the demographic characteristics, mechanism of injury, fracture type, and associated fractures were compiled from all patients' files and operation notes with diagnosis of talar injuries from January 2014 to December 2019., Results: Among 367 patients, 317 (86.4%) males and 50 (13.6%) females with mean age of 31.8 ± 11.6 years were identified. There were three (0.8%) patients with bilateral talar fractures. The most common mechanism of injury was motor vehicle accident (MVA) (46.1%), followed by falls (43.3%), direct trauma (6.2%) and sport injuries (4.4%). About half of the patients injured in MVAs were motorcyclists. Isolated talar body fractures (21.9%) were more common than isolated talar neck (19.2%) or combined body & neck fractures (14.6%). Isolated lateral process fracture is the most frequent fractured process of the talus (14.3%). Hawkin type IIA (39.2%) was the most common type of talar neck, followed by Hawkin type III (22.3%), type I (21.5%), type IIB (14.6%) and type IV (2.3%). Medial malleolus, fibula and calcaneus were the most common associated fractures, respectively., Conclusions: The population that is most affected by talar injury are active young men who are involved in motor vehicle accidents, especially motorcycle crashes, with fracture of body and/or neck of talus being the most common type.

- Abstract
Background: Anthrax is a zoonotic infectious disease that is still considered as a health problem in developing countries. Therefore, the aim of this study was to investigate the incidence and geographical distribution of anthrax using the Geographic Information System (GIS) and predict its incidence in Iran in 2021. Methods: This study is descriptive analytical study. Information on anthrax was obtained from the Center for Communicable Diseases Control during 2010-2015. In the next step, ArcGIS 9.3 was used to prepare geographic maps of the disease incidence and frequency. Therefore, using the Raster Calculator tool, the disease prediction map was drawn. Results: The highest incidence of anthrax during 2010-2015 was observed in the provinces of Kurdistan, North Khorasan, and Chaharmahal and Bakhtiari, respectively. The trend of the incidence of anthrax in Iran had increased from 2010 to 2013, while its incidence decreased in 2014. Based on the results of modeling in Iran, the provinces of Kurdistan, West Azarbaijan, Tehran, and Zanjan, respectively, with 37.16%, 33.83%, 16.78%, and 10.49% of their area (km
2 ) had the highest risk of anthrax disease in the country in the year 2021. Conclusion: Since the provinces of Kurdistan, West Azerbaijan, Tehran, and Zanjan are among the high-risk areas in the country in the coming years, the cooperation between the veterinary organization and the health care system and the vaccination of livestock in these areas can significantly help to control and prevent the disease., Competing Interests: Conflicts of Interest: None declared, (© 2021 Iran University of Medical Sciences.)- Published

- Abstract
Statement of the Problem: Tooth color changes followed by treatment with bioceramic materials are always a matter of concern., Purpose: The aim of the present in vitro study was to compare tooth discoloration that occurs in human teeth filled with ProRoot WMTA (DENTSPLY Tulsa Dental Specialties, Tulsa, OK) and those filled with Nano Fast Cement (NFC) over the course of 3 months., Materials and Method: In this experimental study, Thirty human intact premolars were obtained. The roots of all teeth were removed by a horizontal cut about 2 mm below the cementoenamel junction. The pulp tissues were removed using a barbed broach (Mani, Tokyo, Japan).The teeth were randomly divided to 3 groups (n= 10) including the control (no material), ProRoot WMTA and NFC. The experimental materials were condensed into the crowns and the teeth ends were sealed with light-cure glass ionomer cement (GC Corporation, Tokyo, Japan). The color was assessed at T
BL (baseline; after preparation of the cavities but before placement of the materials), TPO (immediately after placement of the filling material and provisional restoration), T4 (after 4weeks of storage), and T12 (after 12weeks) of storage., Results: The discoloration was evident in all teeth, immediately (TPO ) after applying MTA and NFC. The highest ΔΕ was noted in WMTA at 12 weeks, followed by NFC; however, there was no significant difference between the discolorations induced by these two materials., Conclusion: Similar levels of clinically observable tooth discoloration were detected by using either WMTA or NFC., Competing Interests: Conflict of Interest: Authors have no conflicts of interest to declare., (Copyright: © Journal of Dentistry.)- Published

- Abstract
Breast conflict may represent a woman's unpleasant feelings toward her breasts, which may adversely affect her decision to undertake the procedures for an early detection of breast cancer. The purpose of the present study was to examine the mediating role of breast conflict in cognitive factors, as suggested by the Health Belief Model (HBM), for adopting mammography. In this explanatory cross-sectional study, multistage cluster sampling was employed to recruit 738 women in the age range of 40 to 69 years in Iran. Champion's revised HBM Scale for mammography adoption and the Women's Breast Conflict Scale were used to measure the variables of interest. Generalized structural equation modeling and hierarchical logistic regression were used for data analysis. Breast conflict was negatively associated with perceived barriers of mammography. Perceived barriers were inversely related to self-efficacy, which was positively related to mammography, suggesting the mediating role of perceived barriers and self-efficacy, connecting breast conflict to mammography indirectly. The mediating role of breast conflict in perceived barriers and self-efficacy suggests an indirect link between breast conflict and mammography. Clinicians and public health-care providers must pay attention to women's feelings in formulating and delivering appropriate interventions and consultations.

- Abstract
Background: In the present study, we explored the associations between hypomania, symptoms of depression, sleep complaints, physical activity and mental toughness. The latter construct has gained interest for its association with a broad variety of favorable behavior in both clinical and non-clinical samples. Subjects and Methods: The non-clinical sample consisted of 206 young adults ( M = 21.3 years; age range: 18-24 years; 57.3% males). They completed questionnaires covering hypomania, mental toughness, symptoms of depression, physical activity, and sleep quality. Results: Higher hypomania scores were associated with higher mental toughness, increased physical activity, lower symptoms of depression and lower sleep complaints. No gender differences were observed. Higher hypomania scores were predicted by higher scores of mental toughness subscales of control and challenge, and physical activity. Conclusion: The pattern of results suggests that among a non-clinical sample of young adults, self-rated hypomania scores were associated with higher scores on mental toughness and physical activity, along with lower depression and sleep complaints. The pattern of results further suggests that hypomania traits are associated with a broad range of favorable psychological, behavioral and sleep-related traits, at least among a non-clinical sample of young adults.

- Abstract
Our aim in this cross-sectional study was to investigate the predictors of the stages of change in mammography adoption (MA) based on Health Belief Model among Iranian women. Through multistage cluster sampling, we recruited and interviewed 1131 women older than 40. After statistical adjustment for other risk factors, perceived barriers (OR D 0.84, 95% CI D .81-.87) and benefits (OR D 1.17, 95% CI D 1.11-1.24) were significant predictors for MA. Majority of the women were in the pre-contemplation and contemplation stages of change for MA. Our findings are informative for the development of targeted interventions to foster MA among women.

- Abstract
Aim: The aim of this study was to investigate the mother-father differences in Postnatal Psychological Distress (PPD) and its determinants among the parents with 8-weeks old children., Materials and Methods: In this cross-sectional study, applying simple random sampling, 306 postnatal parents with an 8-weeks old infant in Saqqez County, Iran, were invited to answer the General Health Questionnaire-28 (GHQ-28) items through the telephone interview. Fifty-eight subjects declined to participate in the study (Response Rate = 81.04%). The data were analysed using the SPSS Statistics v. 21., Results: About 16.9% of all the parents had PPD. The difference in the prevalence of PPD in three dimensions between the two groups were statistically significant (p < 0.01): social dysfunction (25.8% for fathers vs. 5.6% for mothers), somatic disorders (21% for fathers vs. 7.3% for mothers), and anxiety (21% for fathers vs. 6.5% for mothers). The mode of delivery of the mothers and the level of education, the number of children, monthly income, and being consent with pregnancy among the fathers were significant predictors for PPD., Conclusion: The level of PPD was more prevalent among the new fathers compared to the new mothers. Among the fathers, but not the mothers, socioeconomic characteristics were contributed to PPD. Considering the differences in risk factors for maternal and paternal PPD, our findings may help family health care providers and policymakers in designing gender-specific intervention programs and diagnosis tools aimed at PPD prevention among new parents.

- Abstract
Background: In spite of developed countries there are progressive trend about HIV/AIDS and its' aspects of transmission in the low socio-economic societies. The aim of this was to explain the youth's behavior in adopting HIV/AIDS related preventive behaviors in a sample of Iranian university students by emphasizing on fear appeals approaches alongside examining the role of self-control trait for explaining adoption on danger or fear control processes based on Extended Parallel Process Model (EPPM)., Methods: A sample of 156 randomly selected university students in Jolfa, Iran was recruited in a predictive cross-sectional study by application of a researcher-designed questionnaire through self-report data collection manner. Sexual high risk behaviors, the EPPM variables, self-control trait, and general self-efficacy were measured as theoretical framework., Results: Findings indicated that 31.3% of participants were in the fear control process versus 68.7% in danger control about HIV/AIDS and also the presence of multi-sex partners and amphetamine consumption amongst the participants. Low self-control trait and low perceived susceptibility significantly were related to having a history of multi-sex partners while high level of self-efficacy significantly increased the probability of condom use., Conclusion: Findings of the study were indicative of the protective role of high level of self-control, perceived susceptibility and self-efficacy factors on youth's high-risk behaviors and their preventative skills as well.
