Abstract
Background: Human brucellosis is a significant public health problem in many middle east countries including Iran. Brucella organisms, which are small aerobic, facultative intracellular coccobacilli, localize in the reproductive organs of host animals, causing abortions and sterility. They are shed in large numbers in the animal’s urine, milk, placental fluid, and other fluids. Dairy product from raw milk are a potential threat to public health in endemic developing countries. The gold standard for the diagnosis of brucellosis is isolation of Brucella species. However, isolation Brucella species is time consuming and needed to level 3 biocontainment facilities and highly skilled technical personnel to handle samples and live bacteria for eventual identification. Handling Brucella species increase risk of laboratory infection. Polymerase chain reaction (PCR) with high sensitivity and specifity overcomed to these disadvantages. The aim of this study was to detect Brucella species in milk from dairy cattle farms in Kerman province, Iran by PCR technique.
Methods: Forty and eight bulk tank milk (BTM) were collected from October 2015 to March 2016 from 48 dairy cattle farm including 4200 cows. DNA of milk samples extracted by lysis buffer and proteinase K method. All milk samples were examined by PCR to detect Brucella-specific DNA targeting IS 711. Positive samples must be showed 317 bp amplified, corresponding to the expected size of the IS 711 genome region in all Brucella species.
Results: Using IS711 primer were detected in 4 samples (8.3%) Brucella spp. from 48 BTM samples in this area.
Conclusion: The results indicate that brucellosis by Brucella species is endemic in the Kerman province dairy farms. Consumption of raw milk dairy products by individual farmers operating under poor hygienic conditions represents an high risk to public health. The need for implementing control measures and raising public awareness on zoonotic transmission of brucellosis are recommended. Vaccination of cattle is recommended for control of bovine brucellosis in enzootic areas with high prevalence rates.

Abstract
Today, the use of information and communication technology (ICT) is an important and key factor in the progress of all organizations, including health-centered and health systems. Given the importance of the subject matter above, these organizations have created a particular transformation and change in order to upgrade their systems in use, one of which is the creation of Electronic Health Records (EHR). This evolving system, by increasing productivity, both by increasing staffing efficiency and by increasing the effectiveness of the treatment process, simplifies the diagnosis path to treatment and prevents the submission of written and bulky reports. Given the ethical principles of protecting the privacy of patients and the confidentiality of their information, how to archive electronic medical records in a secure database is very important. This is one of the most important issues of ethics and hospital managers should provide mechanisms to keep all patient data properly stored and maintained. In this paper, we have tried to provide a model for the Electronic Health Record Hospital, which many of them could use to optimize their medical records systems. The purpose of this model is to accelerate and apply the process of creating electronic records in the health system, especially government hospitals with a large number of patients. By using this model, internal and external interaction of organization is facilitated, and agile responsiveness can be provided at a given time. In addition to the above, with the implementation and operationalization of the model, the possibility of reducing the volume of criticisms and complaints from hospitals will also be realized and the use of drugs will be based on the actual needs of the community and based on individual data. Implementation of this model also has barriers to addressing some of them in this article, but in order to overcome these barriers, more administrative effort and wider governmental support are needed. These efforts in the context of culture-building use of information technology, both among hospital personnel and among patients and healthcare users, are more important.

Abstract
Background: The prevalence of diabetes mellitus due to existence of various factors is growing rapidly. The insulin resistance phenomenon is one of the main underlying causes of this disease, due to various reasons such as a decrease in serum levels of vitamin D3. In this study, we evaluated the relationship between plasma level of vitamin D3 and some other main plasma factors.
Methods: This clinical trial study carried out on type 2 diabetes mellitus subjects who referred to diabetes clinic of Baqiyatallah Hospital in Tehran city during June to September 2016. First demographic data of all patients were collected. Then the blood samples for evaluation of blood glucose, HbA1c, triglyceride, cholesterol, HDL, LDL and vitamin D3 were obtained. Based on plasma level of vitamin D3, diabetic subjects were divided into two separate treatment groups (with and without vitamin D3 deficiency) and then above-mentioned factors were compared between these two groups. Afterward, in group with vitamin D3 deficiency, treatment by vitamin D3 triggered (50000 unit per week for eight weeks orally) until plasma level of vitamin D3 reached above 30 ng/mL. Then, treatment continued by vitamin D3 (50000 Unit per week orally) and calcium (1.5 g/day PO) until 60 days. Finally, the patients were evaluated about fasting blood glucose, HbA1c, HDL, LDL and blood pressure.
Results: In total, 187 subjects (99 men and 88 women) were evaluated in this study. Total hypovitaminose incidence was 0.65% which was higher in subjects with higher body mass index (BMI). Serum content of vitamin D3 and calcium, significantly changed the values of fasting blood sugar (FBS), HbA1c, HDL and TG, but has no significant effects on other factors.
Conclusion: Our results clearly revealed that hypovitaminose vitamin D3 is one of the main factors that can leading to rise in plasma glucose and dyslipidemia occurrence. Also, our data are demonstrated that treatment by vitamin D3 and calcium can modify fasting blood glucose and dyslipidemia in type 2 diabetes mellitus subjects.

Abstract
Background: Aphanizomenon flos-aquae (AFA) is a type of blue-green algae and contains a source of biological compounds. These microalgae have many beneficial health effects. Recently, fucoidan, known sulfated polysaccharide component of AFA algae, has been claimed to stimulate stem-cell mobilization in animal models. Stem cells play an essential role in tissue repair process. In this study, we use excisional full thickness wound model to investigate the effectiveness of trademark AFA extract on skin wound repair process.
Methods: In this experimental study, 21 adult male Wistar rats (weighing 200-250 g) were used and under general anesthesia (intraperitoneally with a ketamine/xylazine solution), two round excisional wounds were created under sterile conditions by a 6 mm punch on the dorsum (paravertebral area) of all rats. Animals were randomly assigned into 3 groups. In groups 1 and 2 (SE-200, SE-400), StemEnhance© (StemTech Health Sciences Inc. British Columbia, Canada) were given respectively 200 or 400 mg/kg by oral gavage once daily and in group 3 (Sham), distilled water (DW) was given to all subjects. Post-wounding gavage of StemEnhance or DW started from 1st day and continued to 7th day. The wound surface area was monitored daily by digital camera and assessed by Image Tool™ software, version 3.5 (UTHSCSA, San Antonio, TX, USA). At 9th day post-wounding animals were sacrificed and repaired tissues were harvested by and assessed by a 8 mm punch. Repaired skin areas were processed for hematoxylin and eosin (H&E). Histopathological parameters of healing including inflammatory cell infiltration, angiogenesis, and fibroblast count were assessed by pathologist. Our study was conducted in the Physiology Department of Medical School, Bushehr University of Medical Sciences, Iran, from October 2016 to March 2016.
Results: Macroscopic imaging of wound area revealed that there was statistically significant difference in wound area reduction between SE-200 group and sham group on day 6 post wounding (P=0.032). Moreover, histological findings showed that the number of neutrophils, macrophages, fibroblasts, and microvessel density decreased in both StemEnhace-treated groups. There were no significant differences between two treatment groups.
Conclusion: According to the obtained results it seems that the extract of Aphanizomenon flos-aquae algae positively affects wound healing process by ameliorating inflammatory response in early healing phases.

Abstract
Background: Chest pain is the most common reason for patients to be referred to the emergency department of hospitals. This study was performed to compare the GRACE and TIMI scores in predicting important cardiovascular events in patients.
Methods: This descriptive-analytical study was performed on 862 cardiac patients who were referred to the emergency department of Taleghani Hospital in Urmia in the period of April 1, 2016 to the end of September 2016 by census method. A checklist containing demographic information, medical history and risk factors was used to collect data. After scoring patients, we examined and followed up both groups over the next 30 days and recorded any cardiovascular events such as sudden death, AMI or immediate revascularization. The data were tested using SPSS16 and descriptive statistics tests. T-test and ROC curve were analyzed.
Results: The results showed that in general, out of 862 patients who were studied (50.3%), 433 were female and (49.7%) 429 were male. Most of the patients were under 65 years old 627 (72.7%) and the age range was (17-91). The highest initial diagnosis of nonSTEMI patients was UA with 811 (94.9%) cases. On the other hand, the highest risk factors of patients were HTN 449(52%), CAD 314 (36.425) and DM 22 (25.55). The highest blood pressure was between (100-120) with 328 cases and serum creatinine between (0.6 to 1.3) with 770 cases. MACE after 30 days in GRACE system 17 people (32.69%) were in high risk group and in TIMI 3 people (37.5%) were in high risk group. In MACE evaluation, the specificity of GRACE system (cutoff point=30) was 89.27 vs. 52.24, the specificity of TIMI system (cutoff point=7.3) and the sensitivity of GRACE 93 (cutoff point=10) versus TIMI 85.71 (cutoff point=8.3) is.
Conclusion: The results showed that GRACE was more sensitive and characteristic than TIMI. |

Abstract
Background: Age is a strong risk factor for increasing the risk of severity and death from Covid-19. The risk of hospitalization for Covid-19 disease increases with age. Since the elderly constitute a large proportion of Covid-19 patients, the present study was performed to evaluate the severity of the disease in the hospitalized elderly due to Covid-19 and the delay in hospitalization and death resulting from it, for better disease management.
Methods: The present retrospective cohort study was performed on 444 elderly patients with Covid-19 admitted from 1 April until late October 2020 in Baharloo Hospital in Tehran, Iran. After being diagnosed using the results of RT-PCR and CT scan, patients, were divided into 3 groups: moderate, severe and very severe based on the severity of the disease. Analysis of variance was used to compare quantitative data and a chi-square test was used to examine qualitative variables in disease groups.
Results: From 444 elderly participants in the study, 73% were infected moderately, 15% severely, and 12% had a very severe form. The mean age was 72.90±8.42 and patients with a very severe form of the disease (75.68±8.28) were older. The average time from the onset of symptoms to hospitalization was 7 days. In the elderly with a very severe form of the disease, respiratory dyspnea (P=0.002) and decreased level of consciousness (P<0.0001) were higher. The average hospital stay was 7 days. In very severe form it lasted up to 11 days. ICU mortality and hospitalization were higher in patients with very severe forms of the disease. With the increasing delay in the days of hospitalization, the severity of the disease and mortality has increased.
Conclusion: The study showed that prolonging the onset of symptoms till hospitalization worsens prognosis and also exacerbates the disease and increases mortality in the elderly.

Abstract
According to the official statistics of the World Health Organization (WHO), cervical cancer is one of the most common cancers among women after breast, colorectal, and lung cancers. The US Centers for Disease Control and Prevention (CDC) says all women have the chance to get the disease, and women over the age of 30 are more likely to get it. However, this cancer is a types of cancer that can be prevented through vaccination. This study aimed to investigate the role of vaccines in the prevention of cervical cancer. In this review study, articles published between 2016-2022 from PubMed, SID, Cochrane Library, Science Direct, and Google Scholar databases were examined. Keywords Papilloma vaccine and cervical cancer in Persian sources and HPV vaccine and Cervical Cancer in English sources were used. The subject search was also performed using MeSH medical subject headings and through the Pubmed database. Vaccination against human papillomavirus is the most cost-effective public health measure against cervical cancer. In many developed and developing countries, serious programs are underway for HPV vaccination and screening for cervical cancer. In most countries, HPV vaccination has been added to their mandatory immunization programs, effectively reducing the incidence of cervical infections and cancers. In countries where vaccination is not complete, health education and screening programs such as PAP smears every 2 years for all women and every year for those with high cancer risk or abnormal smears, have been consolidated. HPV vaccination is highly effective and has been added to immunization programs in many countries. Nowadays, three types of vaccines have been presented, of which the 9-valent Gardasil vaccine is more effective than the other two types, but in terms of cost-effectiveness, the 4-valent Gardasil vaccine is more suggested. Due to the high prevalence of cervical cancer in Iran, it is suggested that the HPV vaccine be used, screening tests be optimized and performed on a regular basis, and ways to prevent cervical cancer be taught.

Abstract
Background: Congenital nasolacrimal duct obstruction (CNLDO) is one of the most prevalent orbital diseases in children and treatment of recalcitrant cases is always challenging. The purpose of this study is to identify the effectiveness of balloon dacryoplasty and stenting in persistent congenital nasolacrimal duct obstruction following previous intubation of nasolacrimal duct.
|
Methods: Our study was an interventional study from January 2015 to January 2018 on 16 lacrimal systems of 11 patients (5 males and 6 females) with congenital obstruction of the lacrimal duct (CNLDO) and a history of unsuccessful probing and stenting, in Farabi Hospital of Tehran (affiliated to Tehran University of Medical Sciences). Children who presented to our hospital and had previously been probed with or without intubation by another surgeon first underwent reprobing and re-intubation with a Crawford tube. Endoscopy of the nasolacrimal system was performed in suspected cases of false stent passage or in the presence of a history indicating nasal pathology. Crawford's Monoka tube was removed after two months. Balloon dacryoplasty with intubation was performed as the third surgery in cases who did not respond to probing and stenting after 3-6 months. The success after six months was evaluated using fluorescein dye disappearance test (FDDT) and also the resolution of the patients' symptoms.
|
Results: The age of the patients was 67±35.01 months (range: 26-121). The site of the canalicular stenosis in our patients was in the common canaliculi or within 2-3 mm from it. After 6 months, surgery was successfully performed in 13 lacrimal systems (81.25%). One patient with congenital lacrimal duct obstruction and Down syndrome and two other patients did not respond to balloon dacryoplasty and stenting and subsequently underwent dacryocystorhinostomy (DCR).
|
Conclusion: Balloon dacryoplasty combined with Monocrawford intubation is an effective surgical procedure that should be considered in cases of congenital nasolacrimal duct obstruction who have not responded to the probing and stenting of the lacrimal system.

Abstract
Retinoblastoma is the most common primary malignant ocular malignancy in children. The management and treatment of retinoblastoma is a very complex process and requires attention to different aspects, such as the stage of the disease based on the International classification of retinoblastoma (ICRB) or International intraocular retinoblastoma classification (IIRC), the genetic status of the tumor and mutations, psycho-social factors of the family and society, cultural beliefs, and available economic resources. From the identification of this malignancy until the beginning of the 20th century (before the introduction of radiation therapy as one of the treatment options), enucleation was the only treatment option for this disease. In addition to not controlling metastatic and extensive features of the disease and increasing the chance of death in these cases, enucleation causes many adverse psychological and aesthetic complications in patients, and especially children, who are the main population affected by this disease. Tremendous progress has been made since the 20th century to identify and invent new methods to preserve the eyes and less invasive treatments (globe salvage treatments), and the set of efforts led to the inventing of new treatment methods such as radiation therapy, systemic chemotherapy, local treatments such as cryotherapy and thermotherapy, intra-arterial chemotherapy and intraocular chemotherapy. In summary, the set of treatments from the beginning until now has gone towards increasing survival, reducing the rate of enucleation and providing more targeted and less invasive treatments. Despite these advances, early diagnosis is the most important prerequisite for better outcomes. However, early detection is influenced by socioeconomic factors and is a major challenge, especially in low- and middle-income countries. In fact, the provision of advanced medical care in high-income areas has provided excellent survival, globe, and vision-saving rates. Unfortunately, these results do not hold true for medical systems in low- and middle-income areas, leading to poor patient outcomes. In this article, we briefly introduce various retinoblastoma treatment methods from the beginning of detection until now, and we assess the evolution of the treatment of this disease from the beginning until now, which has reduced the need for enucleation as a treatment for this disease.

Abstract
Congenital cataract refers to the presence of any opacity in the lens at birth or during early childhood. Cataracts in children can manifest as unilateral or bilateral, congenital or acquired, with specific inheritance patterns or occurring sporadically. Additionally, the condition can be stable or progressive. Congenital cataracts can be associated with certain systemic diseases, or they may occur in the eye of an otherwise healthy child in isolation. Congenital cataract is one of the main causes of blindness in childhood. According to the report of the World Health Organization in 2001, congenital cataract is responsible for about 5 to 20 percent of cases of childhood blindness in the world based on different geographical regions. Untreated cataract in children leads to a tremendous social, economic and emotional burden for the child, family and society. Common complaints associated with congenital cataracts often include leukocoria (white pupil), reduced vision, a child's inability to track objects up close, light sensitivity leading to eye closure, squinting, the presence of either small eyes (microphthalmos) or large eyes (buphthalmos), strabismus (eye deviation), and abnormal eye movements such as nystagmus. Childhood cataract-related blindness can be cured with early detection and appropriate management. Managing pediatric cataracts is a challenge. Increased intraoperative complications compared to adults, tendency to increase postoperative inflammation, associated with complications such as aphakic glaucoma and persistent fetal vasculature, change in refractive status of the eye, and tendency to develop amblyopia, all complicate the achievement of good vision. Congenital cataract has a good prognosis if it is diagnosed early and surgery is performed before 6 weeks. Factors that may adversely affect the outcome, include the presence of unilateral cataract, presence of nystagmus, strabismus, or any ocular defect such as microphthalmos and PFV. Pediatric cataract surgery has evolved over the years, and with improved knowledge about myopic shift and axial growth, outcomes for these patients have become more predictable. Optimal results depend not only on effective surgery, but also on careful postoperative care and visual rehabilitation. Hence, it is the combined effort of parents, surgeons, anesthesiologists, pediatricians and optometrists that can make the difference.

Abstract
Background: Pelvic organ prolapse (POP) is a condition resulting from weakness or damage to the muscles, ligaments, and other supporting structures of the vagina, and it exposes affected women to reduced quality of life and sexual function. The present study examined the symptoms, sexual function, and quality of life of women one year after repair of pelvic organ prolapse.
Methods: This study was a prospective cohort before-after study that was conducted on 200 married women with pelvic prolapse grade 1-4 (POP-Q) in the age group of 47-75 years who underwent reconstructive surgery (anterior and posterior colporrhaphy) in Shahid Beheshti and Al-Zahra hospitals in Isfahan between October 2022 and March 2024. The data collection tools were three questionnaires: Female Sexual Function Index (FSFI), Pelvic Discomfort (PFDI-20) and Quality of Life (SF-36) which were completed before surgery and one year after surgery. Stata software version 17 was used to analyze the data. To compare the scores before and after, paired t-test or Wilcoxon statistical tests were used, to compare the severity of patients' clinical symptoms based on the levels before and after surgery, the symmetry/Bowker test was used, and to compare the status of the sexual function index (impairment/no impairment) before and after surgery, the McNemar test was used and the significance level was considered to be P<0.05.
Results: The mean age of the study participants was 59.5±12.6 years. The majority of the women (157 individuals; 78.5%) were housewives. The mean number of pregnancies was 4.3±2.1, and the mean number of live births was 3.75±1.89. All women included in the study were postmenopausal. The severity of clinical symptoms, sexual dysfunction index status, and median quality of life score were significant between before and after the intervention. The severity of clinical symptoms, the status of the sexual dysfunction index, and the median quality of life score showed significant differences before and after the intervention.
Conclusion: Pelvic prolapse surgery can significantly improve the quality of life and sexual function of patients one year after surgery, in addition to correcting the anatomical structure.
