Abstract
BACKGROUND Cervical cancer is one of the most common cancers in women, the cause of which is mostly human papilloma virus (HPV). The aim of this study was to determine the economic burden of cervical cancer and premalignant lesions associated with HPV infection from a societal perspective. METHODS The study is a partial economic evaluation (cost of illness), which was conducted cross-sectionally in the referral university clinic in Fars province in 2021. The prevalence-based and bottom-up approaches used to calculate the costs, the indirect costs were calculated by human capital approach. RESULTS The mean cost of premalignant lesions associated with HPV infection was USD 2,853 per patient, which 68.57% was direct medical costs. In addition, the mean cost of cervical cancer was USD 39,327 per patient, the largest share of which (57.9%) was related to indirect costs. The mean annual cost of cervical cancer patients in the country was estimated at USD 40,884,609 as well. CONCLUSION Cervical cancer and premalignant lesions associated with HPV infection imposed a significant economic burden on the health system and patients. The results of the present study can help health policymakers with efficient and equitable prioritization and allocation of resources.

Abstract
BACKGROUND Providing intensive care to acute patients is a vital part of health systems. However, the high cost of Intensive Care Units (ICU) has limited their development, especially in low-income countries. Due to the increasing need for intensive care and limited resources, ICU cost management is important. This study aimed to analyze the cost-benefit of ICU during COVID-19 in Tehran, Iran. METHODS This cross-sectional study is an economic evaluation of health interventions. The study was conducted in the COVID-19 dedicated ICU, from the provider's point of view and within one-year horizon. Costs were calculated using a top-down approach and the Activity-Based Costing technique. Benefits were extracted from the hospital's HIS system. Benefit Cost ratio (BCR) and Net Present Value (NPV) indexes were used for cost-benefit analysis (CBA). A sensitivity analysis was performed to evaluate the dependence of the CBA results on the uncertainties in the cost data. Analysis was performed with Excel and STATA software. RESULTS The studied ICU had 43 personnel, 14 active beds, a 77% bed occupancy rate, and 3959 occupied bed days. The total costs were $2,372,125.46 USD, of which 70.3% were direct costs. The highest direct cost was related to human resources. The total net income was $1,213,314.13 USD. NPV and BCR were obtained as $-1,158,811.32 USD and 0.511 respectively. CONCLUSION Despite operating with a relatively high capacity, ICU has had high losses during the COVID-19. Proper management and re-planning in the structure of human resources is recommended due to its importance in the hospital economy, provision of resources based on needs assessment, improvement of drugs management, reduction of insurance deductions in order to reduce costs and improve ICU productivity.

Abstract
Background Fair access to health services is a vital issue in low-and middle-income countries. Therefore, the present study was conducted to evaluate the equity in access to primary health care (PHC) services in southeastern Iran. Methods This household-based survey was conducted on 1128 households in Kerman, southeastern Iran in 2019-20. A multistage probability method was used to select the samples. The online questionnaire was designed and its link was provided to the questioners. After receiving the training, the questioners went to the door according to the sampling guide. The collected data were analyzed at a significance level of 0.05, using the STATA software. The concentration index (CI) was also used to measure inequality in access to PHC services. Results The results showed that there was a significant difference between gender and location in access to PHC services (P < 0.05). However, no significant difference was found between the access rates to PHC services and the variables of age, marital, education, health insurance, and Supplementary insurance (P > 0.05). The mean rate of access to PHC services was 3.51 ± 0.53. Cultural access (3.76 ± 0.54) and timely receipt of PHC services (2.51 ± 0.72) accounted for the highest and the lowest access rates, respectively. The concentration index for the distribution of PHC services among the income-adjusted population was 0.014 (CI 95%: -0.022 to 0.051), indicating pro-rich inequalities in access to PHC services. Conclusion The results indicated that pro-rich inequality, but it was close to the equality line. Also, the access level was assessed as moderate to high. Therefore, planning and policy-making seems essential for reduce inequality, and development and promotion of access to PHC services, especially timely provision of services and organizational access.

Abstract
Background and Aims Primary care and the use of a referral system are essential components of any health system. The aim of this study was to investigate and identify the challenges affecting the performance of the primary health‐care system in Iran. Methods This qualitative study was carried out consisting of 14 interviews with experts and those familiar with the primary care system and its function. Purposive and snowball sampling was used to identify the samples. The recorded files were transcribed and entered into the MAXQDA‐11 software to be analyzed. The conventional content analysis approach was used for data analysis. Results The findings of this study included 72 initial codes classified into 7 main themes and 18 subthemes. Seven main themes consist of governance, manpower, resources, financial management, services delivery, trans‐sectional, and social and cultural. The greatest challenges for Iran's primary health care (PHC) system are governance and human resources problems. Conclusion Various dimensions of Iran's primary care system especially governance and human resources are facing several challenges that threaten its performance and efficiency. Policymakers and planners must address challenges fundamentally and do not get satisfied with superficial reforms that have short‐term and soothing effects. In this regard, enhancing governance functioning can profoundly solve numerous challenges of Iran's primary care system. We also suggest the strengthening of intersectoral collaboration.

Abstract
Objective: Free gingival graft (FGG) procedure is accompanied with a considerable rate of graft shrinkage. This study was aimed to assess the dimensional changes of FGG after recipient site preparation with Er,Cr:YSGG laser and surgical scalpel. Materials and methods: This split-mouth randomized clinical trial evaluated 11 patients with bilateral lack of keratinized gingiva in mandibular premolars. The test side in each patient was prepared with Er,Cr:YSGG laser (3 W power, 300 mJ energy, 10 Hz frequency, long-pulsed mode), whereas the control side was prepared by surgical scalpel. All FGGs were harvested from the palate with standard dimensions of 14 × 9 mm. The graft width, length, surface area, and shrinkage and color match were measured after 1, 3, and 6 months. Postoperative complications, including pain and bleeding were also evaluated using a questionnaire. Results: In both groups, the surface area and width of graft significantly decreased at all time points compared with baseline but the difference in this respect was not significant between the two groups (p > 0.05). In both groups, maximum shrinkage occurred within the first 3 months. In control group, the surface shrinkage in 3 months was significantly greater than the first month (p = 0.025) without significant difference between groups (p = 0.79). The two groups were not significantly different regarding pain score and bleeding score either. On the day of surgery, the test group had slightly lower pain score and higher bleeding score in comparison to the control group without significant difference. The pain and bleeding scores reduced in both groups with no significant difference (p > 0.05). Conclusions: Er,Cr:YSGG laser has promising results for preparation of FGG recipient site and yields results comparable to those of surgical scalpel.

Abstract
OBJECTIVES In this study, we will investigate the effect of hydroxychloroquine on the prevention of novel coronavirus disease (COVID-19) in cancer patients being treated. TRIAL DESIGN This is a two-arm, parallel-group, triple-blind, phase 2-3 randomized controlled trial. PARTICIPANTS All patients over the age of 15 years from 5 types of cancer will be included in the study. Patients with acute lymphoid and myeloid leukemias in the first line treated with curative intent, patients with high-grade non-Hodgkin's lymphoma treated with leukemia regimens, and patients with non-metastatic breast and colon cancer in the first line of treatment will enter the study. INTERVENTION AND COMPARATOR Patients are randomly assigned to two groups: one being given hydroxychloroquine and the other is given placebo. During 2 months of treatment, the two groups will be treated with hydroxychloroquine every other day with a single 200-mg tablet (Amin® Pharmaceutical Company, Isfahan, Iran) or placebo (identical in terms of shape, color, and smell). Patients will be monitored for COVID-19 symptoms during follow-up period. If any COVID-19-related signs or symptoms occur, they will be examined, thoroughly, investigated with a high resolution computerize tomography (CT) scan of the lungs and nasopharyngeal swab assessed by RT-PCR for SARS-CoV-2 virus. This study will be performed in five centers affiliated to Mashhad University of Medical Sciences, Mashhad, Iran. MAIN OUTCOMES The primary end point of this study is to investigate the incidence of COVID-19 in patients being treated for their cancer and receiving prophylactic Hydroxychloroquine. RANDOMIZATION Randomization will be performed using random permuted blocks. By using online website ( www.randomization.com ), the randomization sequence will be produced by quadruple blocks. The allocation ratio in intervention and control groups is 1:1. BLINDING (MASKING) Participants and caregivers do not know whether the patient is in the intervention or the control group. Those assessing the outcomes and data analyzer are also blinded to group assignment. SAMPLE SIZE The calculated total sample size is 60 patients, with 30 patients in each group.

Abstract
INTRODUCTION We examined the association of adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL) gene expressions, as the key regulators of lipolysis, with dietary fat quantity and composition in subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT). METHODS In this observational study, samples were collected from patients undergoing elective abdominal surgery. Participants were categorized into two groups based on their body mass index (BMI) status. Dietary, anthropometric, and biochemical data were collected before surgery. Linear regression was performed to determine the association of dietary fat content with ATGL and HSL gene expressions in SAT and VAT. RESULTS 152 individuals with a mean ± SD age of 40.7 ± 13.2 years and a median (inter-quartile range) BMI of 39.4 (26.5-45.3 kg/m2) participated in this study, of whom 54 were non-obese (BMI<30 kg/m2), and 98 were obese (BMI≥30 kg/m2). Among non-obese participants, positive associations were observed between ATGL mRNA expression and reported intakes of total fatty acids (TFA) (β=0.306, P = 0.025), myristic (β=0.285, P = 0.038), palmitic (β=0.417, P = 0.002), oleic (β=0.333, P = 0.017), dairy trans (β=0.374, P = 0.006), and other trans FAs (β=0.369, P = 0.006) in SAT. In contrast, inverse associations between HSL mRNA expression and reported intakes of TFAs (β=-0.377, P = 0.005), myristic (β=-0.282, P = 0.039), palmitic (β=-0.372, P = 0.006), stearic (β=-0.314, P = 0.020), and oleic acid (β=-0.372, P = 0.007) were observed in SAT. No associations were observed among obese participants, nor in VAT among non-obese individuals. CONCLUSION ATGL and HSL mRNA expressions in SAT were associated with dietary fat quantity and composition among non-obese adults.

Abstract
Background: This study was conducted to synthesize the evidence on the dimensions of performance appraisal of the public health and primary care system through a scoping review and meta-synthesis. Methods: The review conducted systematically in 2018 with a scoping review approach. To identify pertinent studies, the following electronic databases were systematically searched until December 20, 2017: Cochrane, ISI Web of Science, PubMed, Scopus, Science Direct, and Embase. Reviewing the studies found on the search bases was carried out in three stages by two persons individually. According to refined studies, the data were extracted to meet the objectives and respond to the research questions. The thematic analysis was used to identify and categorize the dimensions of performance measurement. Results: Using this process, 20 studies were eligible for our research. The critical points in measuring the performance of the public health field were classified into eight main domains including leadership and stewardship, funding, resource generation, service delivery, quality, accessibility, efficiency/productivity, and community health status. The differences in measurement frameworks are inevitable. One reason for the differences in the health system performance measurement framework is the differences in the data or data collection, analysis, and reporting. Performance measurement in the field of health, especially primary care, was a multidimensional issue. Conclusions: Each of the main dimensions had several sub-criteria, indicating the broadness and complexity of the performance of first-level care providers. Single-dimensional performance measurement could underpin incorrect policies and decisions.

Abstract
Background The prevalence of obesity and its two important phenotypes, the metabolically healthy obese (MHO) and the metabolically unhealthy obese (MUO) are 10.9, 9.1, and 1.8%, respectively, among children and adolescents in Iran. Data on the link between diet quality indices and obesity phenotypes in children and adolescents is scarce. The present study aimed to assess the association of the Dietary Approaches to Stop Hypertension (DASH) score with MHO and MUO, as well as with cardiometabolic risk factors (RFs) in children and adolescents with excess weight. Methods This cross-sectional study was conducted on 341 children and adolescents with excess weight aged 6–13 years, selected from primary schools of Tehran. The DASH score was determined based on eight components using a valid and reliable food frequency questionnaire. Anthropometric measures, insulin, fasting plasma glucose, lipid profile, and physical activity levels were collected. MUO was classified based on two definitions: having 2 or more cardiometabolic RFs, or being insulin resistant determined by a homeostatic model assessment of insulin resistance (HOMA-IR) ≥ 3.16. Multivariable logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for MUO phenotypes and cardiometabolic RFs in each tertile of the DASH score after adjustment for confounders. Results The mean ± SD for age and DASH score was 9.3 ± 1.7 years and 24.0 ± 4.9, respectively. The prevalence of MUO was 62.2% based on RFs, and 43.4% based on HOMA-IR. Participants in the highest tertile of the DASH score had significantly decreased odds for MUO based on HOMA-IR (OR = 0.49; 95% CI: 0.28–0.87) compared with those in the lowest tertile, after adjustment for confounders. However, there were no associations between the DASH score and any of cardiometabolic RFs, or MUO based on RFs (OR = 0.68; 95% CI: 0.38–1.20). Conclusion The DASH score was inversely associated with MUO based on HOMA-IR, but not associated with MUO based on cardiometabolic RFs in this sample of children and adolescents. A DASH-style diet may have favourable effects on insulin sensitivity among children and adolescents with excess weight. Universal definitions for MHO/MUO are required, and longitudinal studies recommended to shed light upon this subject.

Abstract
PURPOSE Scurvy, due to vitamin C deficiency, is commonly referenced as a "forgotten" or "historical" disease. A growing number of case reports challenge this notion. Bone health providers are often consulted early in the presentation of scurvy to evaluate musculoskeletal complaints resulting from impaired collagen production and disrupted endochondral bone formation. In this report, we describe two cases of childhood scurvy. Our objective is to summarize the key features of scurvy for bone health providers, with the goal of raising awareness and facilitating diagnosis in future cases. CASE DESCRIPTIONS Case one occurred in a 12-year-old non-verbal, non-ambulatory female on a ketogenic diet for refractory epilepsy. Clinical findings included hemarthrosis, transfusion dependent anemia, elevated inflammatory markers, and epiphysiolysis. Magnetic resonance imaging (MRI) revealed multi-focal bone marrow signal abnormalities and physeal irregularities. Case two occurred in a typically developing 5-year-old male presenting with limp and knee pain. Symptoms progressed despite casting and immobilization. Mild anemia, elevated inflammatory markers, and multi-focal marrow and physeal MRI abnormalities were identified. Subsequent dietary history revealed total absence of fruit or vegetable consumption. The diagnosis of scurvy was confirmed in both cases by undetectable plasma vitamin C concentrations. Treatment with vitamin C led to rapid clinical improvement. CONCLUSION Scurvy can no longer be considered a historical diagnosis and should not be forgotten when evaluating children with musculoskeletal ailments. Early recognition of the signs, symptoms, and imaging findings of scurvy can reduce the clinical burden of this disease with the timely initiation of vitamin C therapy.

Abstract
The outsourcing of health services has gained prominence over the past decades. Because numerous factors affect outsourcing in the field of health services, identifying and prioritizing these factors is specifically important. This study sought to identify and prioritize the factors affecting outsourcing, and to propose a model for the effective outsourcing of hospital services in Shiraz, Iran. The study drew on an exploratory mixed research method. In the first stage, all the criteria affecting the outsourcing of activities in hospitals were identified through the theoretical framework, a literature review, and interviews with hospital experts. Next, the criteria were finalized and prioritized using the fuzzy best-worst method (BWM). Following the literature review, 34 criteria for outsourcing were identified based on the studies explored and the interviews with the experts; the criteria were categorized into seven dimensions including "strategy", "management", "economy", "quality", "security and keeping patients' records", "service", and "agility." These dimensions formed the final outsourcing model of hospitals in Shiraz. Finally, the fuzzy BWM analysis revealed that "security and keeping patient's records" had the highest priority in outsourcing-related decision-making. The findings can help hospital managers make the right decision concerning the outsourcing of hospital services. The dimensions found in this research might also have been identified in other models, although this study was different in that it concentrated on the criteria in the specialized area of hospital management, while identifying the importance and weights of all the criteria involved.

Abstract
Background: Social issues have short- or long-term as well as positive or negative effects on health systems. Identifying and analyzing events and trends help managers to make the vision and strategic planning. The purpose of this study is to identify the social trends and their impacts on the future of the Iranian health system. Methods: Focus group discussion (FGD) was used to collect the data in 2017--18. The participants were selected through purposive sampling and the snowball method. The discussions were all written and recorded with the consent of the participants. A qualitative content analysis was used to analyze the data. Results: The participants believed that the most important social trends affecting future of health system in Iran are increase health literacy, demographic transition, nutritional pattern, migration and urbanization, marginal settlement, rising unemployment, and increased usage of personal cars. Conclusions: The increase in health problems, healthcare costs, and mortality because of social behaviors and trends are considered as threats to the health system. Therefore, policymakers should reduce their negative effects by taking into account and focusing on these trends and making appropriate plans.

Abstract
Human dendritic cells (DCs) show remarkable phenotypic changes when matured in the presence of helminth-derived products. These modifications frequently elicited a polarization towards Th2 cells and regulatory T cells thus contributing to immunological tolerance against these pathogens. In this study, the interaction between DCs and larvae of the zoonotic anisakid nematode Anisakis pegreffii was investigated. A. pegreffii larvae were collected from fish hosts, and monocyte-derived DCs were cocultured in the presence of the live larvae (L) or its crude extracts (CE). In both experimental conditions, A. pegreffii impacted DC viability, hampered DC maturation by reducing the expression of molecules involved in antigen presentation and migration (ie HLA-DR, CD86, CD83 and CCR7), increased the phagosomal radical oxygen species (ROS) levels and modulated the phosphorylation of ERK1,2 pathway. These biological changes were accompanied by the impairment of DCs to activate a T-cell-mediated IFNγ. Interestingly, live larvae appeared to differently modulate DC secretion of cytokines and chemokines as compared to CE. These results demonstrate, for the first time, the immunomodulatory role of A. pegreffii on DCs biology and functions. In addition, they suggest a dynamic contribution of DCs to the induction and maintenance of the inflammatory response against A. pegreffii.

Abstract
BACKGROUND Examining the conditions for hospital admission and its appropriateness, and continuous investigation of hospital services are important issues that can improve resource productivity, service quality, and hospital efficacy. So, the present study was conducted to determine the appropriateness of the services provided in Yasuj educational hospitals. METHODS This descriptive-analytical study was carried out on 204 hospitalized patients who were selected through multistage quota sampling in 2016. The appropriateness evaluation protocol (AEP) was used to collect the data. Analytical tests such as paired t-test, chi-square test, and Fisher's exact test were used to determine the relationship between appropriate and inappropriate admission and hospitalization and demographic characteristics. The data were analyzed using the SPSS18 statistical software. RESULTS A total of 980 days of stay were evaluated, and according to the AEP, 35 days of hospitalization were considered inappropriate (3.57%). The mean hospitalization duration was 6/16 ± 5/53 days. The results showed that inappropriate admission and hospitalization rates were respectively 0.6% and 13.8%. CONCLUSION Unnecessary admissions and hospitalizations can be considered as one of the challenges of the health system. Reducing unnecessary hospitalization will increase hospital productivity, reduce the waiting list and hospitalization costs, and also reduce the risk of exposure to hospital infections. In order to prevent inappropriate admissions and unnecessary hospitalizations, special measures can be taken, including the use of clinical guidelines, modification of the discharge process, and modification of the lower levels of the service providing system.

Abstract
INTRODUCTION Lack of a clear policy for the development of health human resources has created inconsistencies. These imbalances are threats to the health system to achieve its goals. Therefore, the development of human resources through proper performance of higher education health system is an important part of the policy development process of the health sector. The present paper aims to introduce the methods applied for the compilation of evolution and innovation program of medical sciences training as well as the most important directions for evolution and innovation. METHODS In this study, we evaluated the methodology for designing packages of Iran's higher education health system evolution and innovation. For this purpose, the evaluation of the policy process was conducted based on Michelle and Scott's policy process models. This policy evaluation model starts by problem identification and definition and continue by agenda setting, policy formation, legitimation, implementation, evaluation, and policy modification, using the proper feedback. Qualitative content analysis method was used as a research method for subjective interpretation of the content of the text data. RESULTS Twelve policies, 68 strategies and their translation in the health system were adopted in a comprehensive plan for higher health education. Eleven practical packages were also developed in order to implement these policies as packages for reform and innovation in medical education. These packages were organized based on the IPOCC pattern. CONCLUSIONS The lack of a comprehensive look at each project or program could bring about irreparableness consequences. However, the MoHME of Iran, relying on the integration of health higher education with health care system and comprehensive method used for transformation and innovation plan in the field of health higher education could take an important step towards improving the nation's health.

Abstract
BACKGROUND Sufficient and sustainable financing of the health system is essential for improving the health of the community. The health systems financing of the EMR countries is facing the challenge. Assessment and ranking of healthcare financing can help identify and resolve some challenges of health systems. So, the aim of this study is to evaluate and rank the condition of the health sector financing in the EMR countries. METHODS This study was a cross-sectional study. The data was of secondary type, extracted from the official WHO and World Bank data. The six healthcare financing indicators in a 10-year interval (2005-2014) in 19 EMR countries analyzed using Grey Relation Analysis and Shannon Entropy. RESULTS On average, the countries in the EMR region spent 4.87% of their GDP on the health sector. Jordan and Qatar allocated the highest (8.313) and the lowest (2.293) percentages of their GDP to the health sector, respectively. The results showed That Qatar was in a better condition than other EMR countries during 2005-2014 in terms of the health system financing and earned the first rank. After that, the UAE and Kuwait were ranked second and third. CONCLUSIONS There is a lot of inequality among the EMR countries in terms of health financing. However, our findings confirmed that only increasing the total health expenditure in a country would not improve its financing status compared to other countries, but it also depends on financing methods.

Abstract
Background: Health information systems offer many potential benefits for healthcare, including financial benefits and for improving the quality of patient care. The purpose of District Health Information Systems (DHIS) is to document data that are routinely collected in all public health facilities in a country using the system. Objective: The aim of this study was to examine the strengths and operational challenges of DHIS2, with a goal to enable decision makers in different counties to more accurately evaluate the outcomes of introducing DHIS2 into their particular country. Method: A review of the literature combined with the method of meta-synthesis was used to source information and interpret results relating to the strengths and operational challenges of DHIS2. Databases (Embase, PubMed, Scopus and Google Scholar) were searched for documents related to strengths and operational challenges of DHIS2, with no time limit up to 8 April 2017. The review and evaluation of selected studies was conducted in three stages: title, abstract and full text. Each of the selected studies was reviewed carefully and key concepts extracted. These key concepts were divided into two categories of strengths and operational challenges of DHIS2. Then, each category was grouped based on conceptual similarity to achieve the main themes and sub-themes. Content analysis was used to analyse extracted data. Results: Of 766 identified citations, 20 studies from 11 countries were included and analysed in this study. Identified strengths in the DHIS were represented in seven themes (with 21 categories): technical features of software, proper management of data, application flexibility, networking and increasing the satisfaction of stakeholders, development of data management, increasing access to information and economic benefits. Operational challenges were identified and captured in 11 themes (with 18 categories): funds; appropriate communication infrastructure; the need for the existence of appropriate data; political, cultural, social and structural infrastructure; manpower; senior managers; training; using academic potentials; definition and standardising the deployment processes; neglect to application of criteria and clinical guidelines in the use of system; data security; stakeholder communications challenges and the necessity to establish a pilot system. Conclusion: This study highlighted specific strengths in the technical and functional aspects of DHIS2 and also drew attention to particular challenges and concerns. These results provide a sound evidence base for decision makers and policymakers to enable them to make more accurate decisions about whether or not to use the DHIS2 in the health system of their country.

Abstract
BACKGROUND In immunocompromised patients suffering from invasive fungal infections, rapid identification of fungal species is important since the appropriate treatment is usually related to the responsible species. We describe here, an assay based on combination of PCR and reverse line blot hybridization (PCR/RLB) for differentiation causative agent of fungal infections. MATERIALS AND METHODS We performed PCR/RLB assay on 10 reference strains, which include Aspergillus species (A. fumigatus, A. flavus, A. niger, A. terreus, and A. clavatus), Mucor circnelloides, Rhizopus oryzae, Alternaria alternata, Cladosporium herbarum, and Fusarium solani. Besides, twenty-two clinical specimens from patients with proven fungal infections were analyzed for the identification of species. The obtained results were then compared with the results of culture and sequence analysis. RESULTS The fungal species-specific oligonucleotide probes were able to distinguish between all species represented in this study with the exception of cross-reactivity between A. niger and A. fumigatus species. Two specimens, which were represented as mixed fungi in culture, were identified properly by this method. Results of the RLB assay were concordant with the culture and ITS sequencing results. CONCLUSION Our result demonstrate that the RLB assay potentially is suitable for rapid and simultaneous identification of variety fungal pathogens directly from culture as well as from clinical specimens.

Abstract
BACKGROUND AND OBJECTIVE Referral systems are relatively easy in terms of design, but implementing them is extremely difficult. Considering the three levels of primary healthcare, access of people to specialized services through a referral system is possible. With regard to the importance of a referral system in a family physician program, this study was performed to assess the function of the referral system in the family physician program in Jiroft University of Medical Sciences. METHODS This cross-sectional study was performed in the first half of 2014. The sample size included 700 patients selected using multistage sampling. Firstly 30% of health centers were randomly selected as a cluster. Then, the patients were randomly selected from each cluster. The study data were collected through a questionnaire consisting of 2 parts - demographic variables and the rules of the referral system. Data were analyzed using descriptive statistics, Chi Square, and Logistic Regression. RESULTS From 700 patients who received the level 2 services, 69% of cases were female and 31% were male. One hundred eighty-two cases (26%) had referral form from health house. Only 56.4% of persons referred to the centers because of diagnosis of the family physician. For 34% of cases, the specialists wrote the results of their evaluation in feedback form. Four hundred sixty-three patients did not return to their family physician because of lack of knowledge. CONCLUSION The referral situation to level 2, in the present study was poor. Ease of access to specialized services level 2, and educational intervention for healthcare staff and familiarizing people with the objectives of the family physician program and referral system are recommended.

Abstract
BACKGROUND The aim of this study was to investigate knowledge, attitude and practice (KAP) of cardiovascular disease (CVD) patients about their oral health status. METHODS In this cross-sectional study, we analyzed the data of 150 CVD patients that collected by a self-administered questionnaire consists of demographic characteristics and KAP. Oral health indicators calculated based on the results of oral examination by an expert dentist. RESULTS CVD patients had an overall moderate level of knowledge and attitude, but their practice was lower than moderate. There were important associations between knowledge scores with gender, education, residential area and financial status, between attitude scores with education and residential area, and between practice scores with education and financial status. There were no associations between KAP and age, marital status or job. Significant positive correlations were found between KAP components. Significant negative correlations were found between oral hygiene index with knowledge and practice. CONCLUSION The practice of heart disease patients about their oral health was poor, and declares that increasing awareness and attitude may not promote practice. Efficient programs are needed to promote oral health practice of adult populations in special groups.

Abstract
Anaphase promoting complex (APC) controls cell cycle and chromosome segregation. The APC activation occurs after binding of co-activators, cdh1 and cdc20. Cdh1 plays a role in cancer pathogenesis and is known as a potential drug target. The main aim of this study was prediction of 3D structure of cdh1 and designing the inhibitory compounds based on the structural model. First, 3D structure of cdh1 was predicted by means of homology modelling and molecular dynamics tools, MODELLER and Gromacs package, respectively. Then, inhibitory compounds were designed using virtual screening and molecular docking by means AutoDock package. The overall structure of cdh1 is propeller like and each DW40 repeat contains four anti-parallel beta-sheets. Moreover, binding pocket of the inhibitory compounds was determined. The results might be helpful in finding a suitable cdh1 inhibitor for the treatment of cancer.

Abstract
Increasing use of fine needle aspiration for oncological diagnosis, while minimally invasive, poses a challenge for molecular testing by traditional sequencing platforms due to high sample requirements. The advent of affordable benchtop next-generation sequencing platforms such as the semiconductor-based Ion Personal Genome Machine (PGM) Sequencer has facilitated multi-gene mutational profiling using only nanograms of DNA. We describe successful next-generation sequencing-based testing of fine needle aspiration cytological specimens in a clinical laboratory setting. We selected 61 tumor specimens, obtained by fine needle aspiration, with known mutational status for clinically relevant genes; of these, 31 specimens yielded sufficient DNA for next-generation sequencing testing. Ten nanograms of DNA from each sample was tested for mutations in the hotspot regions of 46 cancer-related genes using a 318-chip on Ion PGM Sequencer. All tested samples underwent successful targeted sequencing of 46 genes. We showed 100% concordance of results between next-generation sequencing and conventional test platforms for all previously known point mutations that included BRAF, EGFR, KRAS, MET, NRAS, PIK3CA, RET and TP53, deletions of EGFR and wild-type calls. Furthermore, next-generation sequencing detected variants in 19 of the 31 (61%) patient samples that were not detected by traditional platforms, thus increasing the utility of mutation analysis; these variants involved the APC, ATM, CDKN2A, CTNNB1, FGFR2, FLT3, KDR, KIT, KRAS, MLH1, NRAS, PIK3CA, SMAD4, STK11 and TP53 genes. The results of this study show that next-generation sequencing-based mutational profiling can be performed on fine needle aspiration cytological smears and cell blocks. Next-generation sequencing can be performed with only nanograms of DNA and has better sensitivity than traditional sequencing platforms. Use of next-generation sequencing also enhances the power of fine needle aspiration by providing gene mutation results that can direct personalized cancer therapy.

Abstract
BACKGROUND Cardiovascular diseases are the most common cause of death in Iran. Moreover, periodontal diseases are very common in our country. In this study, we have designed a standardized questionnaire for evaluating knowledge, attitude, and practice (KAP) of Iranian adult patients with cardiovascular diseases about oral health. METHODS For designing and standardizing a self-administered questionnaire, we performed a cross-sectional pilot study on 51 cases with periodontal complaints. A dentist carried out the physical examination to determine oral health indicators. Twelve experts and ten lay people of the target population answered questions about validity. Cronbach's alpha, factor analysis, and Pearson correlation coefficients were used in the analysis. RESULTS The cases of this pilot study were middle aged, with moderate financial and health status, but low oral health and educational level. Debris score was correlated with all other physical exam findings except decay, missing, and filled (DMF). Reliability was 0.826 according to Cronbach's alpha score. Face validity was higher than 80%. Content validities of the whole of the questionnaire were 85.98% for clarity, 78.05% for relevancy, 85.16% for simplicity, and 82.32% for consistency of each question with the question set. Factor analysis showed that 15 components explain 74% of the total variance. CONCLUSION This questionnaire is culturally adjusted and appropriate for our community, valid and reliable, and sufficiently estimates the variance of the oral health status. It can be used as a standard tool in further studies in adult population of the Iranian middle aged patients with low level of education and moderate socioeconomic status.

Abstract
Recently, the combining of different drugs has greatly improved response and survival rates in gynecological malignancies. Results are however far from being satisfactory. Treatments used in case of advanced or recurrent disease offer limited results in terms of long-term responses. The urgent need for new and more effective treatments has prompted researchers to investigate and propose new therapeutic strategies. One of the most interesting approaches that are being explored is constituted by immunotherapy. Currently, immunotherapeutic strategies include vaccination with peptide, viral vectors, carbohydrates and antiidiotypic antibodies. In addition, cell based immunotherapy has been adopted in vitro activated lymphocytes and dendritic cells. Most experience has been acquired in ovarian cancer and cervical cancer. Little has been investigated in endometrial and rare gynecologic neoplasms.The clinical experiences and results achieved with immunotherapy in this setting of patients have been reviewed and the future avenues that are currently being explored have also been discussed.

Abstract
Integrin very late antigen-4 (VLA4) is induced during inflammation and can regulate monocyte migration. It has been implicated in atherogenesis, a significant concern in systemic lupus erythematosus (SLE). The aim of this study was to define VLA4 expression in SLE monocytes. Flow cytometry, reverse transcription polymerase chain reaction, Western blotting, and immunohistochemistry staining with confocal microscopy were used to evaluate VLA4 expression in SLE patients and controls. We found elevated expression of VLA4 in SLE patients with significantly increased VLA4 staining intracellularly compared to control. Exposure of control monocytes to SLE sera or immune complexes led to increased intracellular expression, and immune complexes were capable of driving redistribution of surface VLA4 to the cytoplasm. Therefore, VLA4 was found to be subject to complex regulation with SLE sera driving both RNA expression and redistribution of protein. Stimulation of SLE monocytes with a VLA4 ligand induced significant TNFα expression, confirming a functional effect. This behavior may contribute to increased atherosclerosis and monocyte infiltrates in end organs.

Abstract
DNA methyltransferase 3A (DNMT3A) is mutated in a subset of de novo acute myeloid leukemia patients and is associated with poor overall and event-free survival. Because routine Sanger sequencing of the 23 DNMT3A exons is impractical in clinical laboratories, we developed a high-throughput method using high-resolution melting (HRM) analysis, which identifies sequence variants by detecting subtle changes in the melting patterns of mutant DNA in comparison with WT sequences. DNA from 104 acute myeloid leukemia patients was tested for mutations in 12 exons encoding 3 major functional domains of DNMT3A: the PWWP (proline-tryptophan-tryptophan-proline) domain (exons 8 to 10), the ADD (ATM-DNMT3-DNMT3L) zinc finger, and the methyltransferase domains encoded by exons 15 to 23. HRM analysis identified 20 of 104 patient samples as variants, which we confirmed by Sanger sequencing. Codon 882 of exon 23 was mutated at the highest frequency with an occurrence rate of 11.5%. All HRM WT calls were confirmed to be devoid of mutations by Sanger sequencing. We also identified seven novel and previously unreported DNMT3A mutations. Structural modeling showed seven of the eight missense mutations detected in our study increased the free energy, destabilized protein, and altered solvent accessibility, suggesting their loss-of-function nature. These data demonstrate HRM analysis to be a higher throughput, sensitive, and efficient alternative to Sanger sequencing for detecting DNMT3A mutations in the clinical diagnostic laboratory.

Abstract
The temporomandibular joint (TMJ) is a specialized synovial joint essential for the function of the mammalian jaw. The main components of the TMJ are the mandibular condyle, the glenoid fossa of the temporal bone, and a fibrocartilagenous disc interposed between them. The genetic program for the development of the TMJ remains poorly understood. Here we show the crucial role of sprouty (Spry) genes in TMJ development. Sprouty genes encode intracellular inhibitors of receptor tyrosine kinase (RTK) signaling pathways, including those triggered by fibroblast growth factors (Fgfs). Using in situ hybridization, we show that Spry1 and Spry2 are highly expressed in muscles attached to the TMJ, including the lateral pterygoid and temporalis muscles. The combined inactivation of Spry1 and Spry2 results in overgrowth of these muscles, which disrupts normal development of the glenoid fossa. Remarkably, condyle and disc formation are not affected in these mutants, demonstrating that the glenoid fossa is not required for development of these structures. Our findings demonstrate the importance of regulated RTK signaling during TMJ development and suggest multiple skeletal origins for the fossa. Notably, our work provides the evidence that the TMJ condyle and disc develop independently of the mandibular fossa.

Abstract
BACKGROUND The aim of this study was to assess the performance of Antigen B (AgB) isolated from different Echinococcusgranulosus intermediate hosts and from different cyst locations for immunodiagnosis of human cystic echinococcosis (CE). METHODS Hydatid cyst fluids were collected from lung and liver cysts of sheep, liver cysts of goats, lung cysts of camels and cattle, and liver cysts of human. AgB was purified from each of these hydatid cysts fluids. Serum samples obtained from 47 pathologically confirmed cases of CE along with 30 sera samples from non-CE patients and 40 sera from healthy individuals were tested by ELISA using AgB prepared from different hosts or cyst locations. RESULTS The highest sensitivity (97.8%) for diagnosis of CE was seen with AgB prepared from human liver cysts. This maximal sensitivity was followed by AgB isolated from those of sheep liver and lung cysts. The least sensitivity was found with AgB prepared from bovine lung cysts. The highest specificities (97.1%) were observed with AgB isolated from human liver cysts followed by those of sheep and goat liver cysts while the lowest specificity was seen with AgB isolated from bovine lung cysts. In view of the specificities and sensitivities of the different AgB, the best validity was found for AgB prepared from human liver cysts while the least validity was found with AgB prepared from bovine lung cysts. CONCLUSION For any AgB-based tests, obtaining of the antigen from one of these sources will significantly increase the diagnostic sensitivity and specificity of the assay.

Abstract
In Peninsular Malaysia, a large proportion of malaria cases occur in the central mountainous and forested parts of the country. As part of a study to assess remote sensing data as a tool for vector mapping, we conducted entomological surveys to determine the type of mosquitoes, their characteristics and the abundance of habitats of the vector Anopheles maculatus in malaria endemic areas in Pos Senderot. An. maculatus mosquitoes were collected from 49 breeding sites in Pos Senderot. An. maculatus preferred to breed in water pockets formed on the bank of rivers and waterfalls. The most common larval habitats were shallow pools 5.0-15.0 cm deep with clear water, mud substrate and plants or floatage. The mosquito also preferred open or partially shaded habitats. Breeding habitats were generally located at 100-400 m from the nearest human settlement. Changes in breeding characteristics were also observed. Instead of breeding in slow flowing streams, most larvae bred in small water pockets along the river margin.

Abstract
Dendritic cells (DCs) are able to orchestrate innate and acquired immunity and can activate and sustain a long-lasting anti-tumor immune response in vivo when used as anti-tumor cell therapy. The selection of the antigen and the choice of its formulation are key points in designing anti-cancer DC-based vaccines. Cell released vesicles/exosomes have been shown to transfer antigens, HLAI/peptide complexes and co-stimulatory molecules to recipient cells. In this study we describe the generation of an allogenic microvesicle cell factory in which the expression of a specific tumor antigen was combined to the expression of co-stimulatory and allogeneic molecules. The DG75 lymphoblastoid cell line was selected as microvesicle producer and transfected with ErbB2, as tumor antigen prototype. The shed microvesicles transferred antigenic components to recipient DCs, increasing their immunogenicity. DC pulsing resulted in cross-presentation of ErbB2 both in HLAI and HLAII compartments, and ErbB2-specific CD8+ T cells from cancer patients were activated by DCs pulsed with vesicle-bound ErbB2. The microvesicle cell factory proposed may represent a source of cell free immunogen to be used for DC-based cancer therapy.

Abstract
The purpose of this research was to investigate effect of dietary betaine on intestinal morphology after an experimental coccidiosis. Hence a total of 189 male and female broiler chicks were randomly assigned to 9 floor cages. Chicks were fed a basal diet supplemented with 0, 0.6 or 1.2 g kg(-1) betaine. All birds were inoculated orally with Eimeria oocysts on day 28. Duodenal morphology parameters and lesions were scored by microscopic observation on intestine samples which were taken at day 42 of age. Adding 1.2 g kg(-1) betaine to diet diminished intestinal lesions (p < 0.05). Dietary supplementation with 0.6 or 1.2 g kg(-1) betaine significantly (p < 0.01) increased intraepithelial lymphocytes as well. Level of additive betaine had no effect on the ratio of villus height/crypt depth or villus surface area. Lamina propria of duodenum became thicker in the intestine of chickens which received more supplemental betaine via their diet. In conclusion, since the number of intraepithelial lymphocytes and thickness of lamina propria represent the condition of gut immune response, it seems that dietary betaine may immunomodulate the gastrointestinal tract of broilers. In addition, betaine effect on villus morphology measured later in life differed from what had been measured already earlier in life of the chicks.

Abstract
BACKGROUND AND OBJECTIVE The effect on bone regeneration, of adding pamidronate disodium to bovine-derived hydroxyapatite, was histologically evaluated, using the sheep bone model. MATERIAL AND METHODS Twenty-four intrabony defects were prepared in the lower jaw of eight sheep using trephine 6 mm burs. One cavity was left unfilled and the other two were filled with bovine-derived hydroxyapatite (BioOss) alone (control group) or with bovine-derived hydroxyapatite mixed with pamidronate disodium (Aredia) (case group), respectively. After 6 wk, the animals were killed and the coded samples observed using an optical microscope. The percentage of regenerated bone, number of osteoclasts and amount of inflammation was recorded. Statistical analysis was carried out using chi-square and Mann-Whitney U-tests. RESULTS The results manifested a significant difference in the amount of bone formation, with the most being observed in the case group and the least in the negative-control group (p<0.001). Significantly fewer osteoclasts were observed in the case group than in the other groups (p<0.001). The amount of inflammation did not seem to differ within the case and control groups (p>0.05). CONCLUSION Adding pamidronate disodium to bovine-derived hydroxyapatite improves its osteoconductive and regenerative specifications. Further study should determine the systemic effects of a single local administration of these drugs, and their appropriate dose and type, with minimal risk.
