Abstract
Cut out or extrusion of the lag screw from the superior aspect of head and neck of the femur is one of the most common and devastating complications of the surgery of the intertrochanteric fractures with DHS. The exact cause of this complications is unknown, but it seems to be related to osteopenia, inappropriate position of lag screw inside head of the femur and inability of DHS to slide inside the barrel, which is the most ignored risk factor. We used short barrel Dynamic Hip Screw (DHS) for fixation of the intertrochanteric fractures in Dimon and Hughston procedure in 16 patients with unstable fracture, from may to August 2000. The only patient suffered from cut out is the one with static position of DHS in the center of the head. The other complications were delayed ::::union:::: in one, disingagement of the lag screw and side plate despite using compression screw, and one case of significant limb length discrepancy 6 months after surgery, mild limbing was the rule and the average of harris scores was 76. We think that, it is possible to reduce the rate of cut out with choosing short barrel DHS instead of the standard one, while using short length lag screw.

Abstract
Background: Since the systemic steroids are introduced in Pemphigus Vulgaris treatment, the prognosis of disease improved significantly. This study was designed to evaluate determining factors in the prognosis of pemphigus vulgaris in Iranian patients.
Methods: In this study, 119 patients with documented pemphigus vulgaris who had presented to Razi Hospital from 2001 until 2003 were included. These patients had presented for the first time and treated with prednisolone and Azathioprine. Morality rate, minor and major relapses and duration of first remission had been defined as prognostic criteria and correlation between them and other demographic variables and disease characteristics were investigated.
Results: The majority of patients (84.1%) were followed for more than one year. The major recurrence and minor recurrence occurred in 28(23.5%) and 65(54.6%) of patients respectively, no case of mortality was observed. In patients who received treatment six months or less after onset of disease the frequency of major recurrence was less than the others. 18(17.8%) vs. 12(41.4%), (p=0.009). Duration of primary remission more than one year was detected in most of the patients (64.7%). In patients with less than 10 initial cutaneous lesions, period of primary remission was longer than the other patients. (p=0.009). Shorter duration of primary remission were noted in older patients (age>50) in comparison with younger patients (age≤50, p=0.04).
Conclusions: Male gender, old age, interval more than 6 months between onsets of symptoms to initial treatment and more than 10 skin lesions on admission, are associated with poor prognosis of pemphigus vulgaris.

Background: Recent studies present a
high prevalence of multiple sclerosis (MS) in Iran. Treatment with interferon is now the first choice in management
of MS. CinnoVexTM (an interferon beta 1-a) is available in
Iran, with achievement of the technology of producing beta interferon. The aim of
the present study is to evaluate the efficacy and safety of CinnoVexTM in a national study named CINA study.
Methods: This study was conducted from 2007 to 2008 in cities of Tehran, Isfahan, Mashhad,
Tabriz, and Shiraz. Patients with relapsing/remitting MS with 16-50 years of age and EDSS of <4 received CinnoVexTM (30µg/week, IM) after diagnosis by a neurologist. EDSS, drug side effects, and frequency of relapse were evaluated for one year
in four 3-month visits.
Results: A total of 1050 patients entered the study. Complete data
were collected from 627 (60%) patients. Mean age was 30.7±8.6 year and 514 (82%) were female. The most common onset presentations
were sensory symptoms (44%). Changes of EDSS through the study showed a significant decrease in the last 3-month of evaluation (p<0.05). Drug side effects
were observed in 47%, 50%, 61%, and 61.4% (p>0.05) and relapse was occurred in 13.4%, 15.7%, 16.9%, and 2.4% of the patients in the first, second, third,
and forth evaluation visits (p=0.001), respectively.
Conclusion: CinnoVexTM prevents progression and improves clinical course of MS. The conventional side
effects of beta interferon therapy, however, are observed with CinnoVexTM.

Abstract
Background: Numerous evidences indicate that various environmental stresses during
pregnancy affect physiological behavior of the offspring. This experimental
study was designed to investigate the effect of noise stress during prenatal
period of rats on spatial learning and memory and plasma corticostrone level in
postnatal life.
Methods: Three groups of pregnant rats were given daily noise stress with durations of
two and/ or four hours in last week of pregnancy period. The fourth group was
left unstressed. The male offspring from the unstressed and different stressed
groups were assigned as controls and stressed groups. The animals were
introduced to a spatial task in Morris water maze 4
trials/day for five consecutive days. The probe test was performed on the 5th day of the experiment. The delay in findings and the distance passed to locate
the target platform were assessed as the spatial learning.
Results: Our results showed that prenatal exposure to noise stress for two and/ or four
hours a day, leads to impaired acquisition of spatial learning in the postnatal
animals. The plasma level of corticostrone in the two stressed groups of rats
markedly matched with their behavioral function. Prenatal exposure to 1-
hour noise stress revealed no effects on the offsprings' behavior and plasma
corticostrone level.
Conclusion: Based on our study results, it seems that applied range of stress which is
executed through the noise stress could increase the plasma corticostrone level
and could decrease spatial learning and memory of adult male offspring.

Abstract
Background: Use of certain antipsychotic drugs has severe effects on fertility in males. Hypothalamus and hypophysial impressions and changes in plasma hormones concentration like prolactin, LH and FSH can affect sperm production. In this study, we investigated the effects of sulpiride on sperm quality, maturation and DNA damage.
Methods: Twenty for adult male mice (age: 6-8 weeks) were divided into three groups. The treatment group received 40 mg/kg sulpiride solution and the control sham group was given carrier of the drug intraperitoneally (IP) daily for 45 days but the control group received nothing. Finally, all the mice were sacrificed by cervical dislocation and their cauda epididymis were removed surgically. The excised specimens were placed in 1 ml HTF medium and incubated for 30 min in CO2 incubator to allow the spermatozoa to swim out. Later, sperm count, motility and viability were analyzed. Additionally, sperm chromatin quality and DNA integrity were assessed by aniline blue and acridine orange staining.
Results: Significant decrease in sperm motility and count were observed in the treatment group while the number of abnormal sperm increased as compared with the other two groups. Sperm viability and DNA maturation showed significant reduction and the rate of DNA damage increased in comparison with the control sham and the control groups (P<0.05).
Conclusion: The study showed that sulpiride has negative effects on sperm parameters in treated animals and in some cases it could cause secondary infertility.

Abstract
Background: There are conflicting reports about zinc, a trace element, in the pathogenesis of hypertension and other cardiovascular diseases. The aim of this study was to evaluate the role of zinc in high blood pressure.
Methods: We conducted this study on 80 patients with primary (idiopathic) hypertension and 80 normotensive people with similar age who attended to Tehran Heart Center between 2007 and 2008. We examined the effect of zinc concentration on blood pressure in both sexes in four age groups (41-50, 51-60, 61-70 and 71-80 years old). We measured plasma zinc concentration by atomic absorption.
Results: The mean plasma zinc concentrations were 0.456±0.04 µg/ml and 0.551±0.055 µg/ml in patients with hypertension and in normotensive people, respectively, (P≤0.05). Nevertheless, the mean plasma zinc concentrations were 0.494 µg/ml and 0.486 µg/ml in men with and without hypertension, respectively. The mean plasma zinc concentrations of women with and without hypertension, respectively were 0.415 µg/ml and 0.596 µg/ml, showing a significant difference between two groups (P≤0.001). Moreover, there was a significant difference in plasma zinc concentration between hypertensive and normotensive people in 51 to 60 years age group (P≤0.05), but difference were not significant between other age groups.
Conclusion: The results of this study revealed the relationship between the decrease in plasma zinc concentration and increase in blood pressure in women and in the men aged 51 to 60 years.

Abstract
Background: Diabetes mellitus affects numerous intracellular metabolic processes, which are reflected by changes in the concentration of some plasma constituents. Particularly, the disease may indirectly undermine some functions of the nervous system including learning and memory through altering oxidative stress status. On the other hand, probiotics can enhance the antioxidant capacity. This study was designed to evaluate the effects of probiotics on spatial memory, maze learning and indices of oxidative stress in diabetic rats.
Methods: In this experimental study, 40 male Wistar rats were randomly allocated to 4 groups (n=10 for each): Control (CO), Control probiotic (CP), Control diabetic (DC), and Diabetic probiotic (DP). The probiotic supplement, including Lactobacillus acidophilus, Lactobacillus fermentum, Bifidobacterium lactis (334 mg of each with a CFU of ~1010), was administered through drinking water every 12 hours for 8 weeks. Using morris water maze (MWM), spatial learning and memory were evaluated. Serum insulin and oxidative stress indices, including superoxide dismutase (SOD) and 8-hydroxy-2'-deoxyguanosine (8-OHdG), were measured by standard laboratory kits.
Results: Oral administration of probiotics improved impairment of spatial learning (P=0.008) and consolidated memory (P=0.01) in the rats. Moreover, probiotic treatment increased serum insulin (P<0.0001) and serum superoxide dismutase activity (P=0.007) while it decreased their blood glucose (P=0.006) and 8-OHdG (P<0.0001).
Conclusion: Probiotic supplementation reversed the serum concentrations of insulin and glucose along with an increase in antioxidant capacity in diabetic rats. It also improved spatial learning and memory in the animals. Relevancy of the metabolic changes and behavioral functions need to be further studied.

Abstract
Background: Environmental signals have an essential role in the maturation of neural circuits during critical period of brain development. It has been shown that, change in visual signals during critical period of brain development changes structure and function of glutamate receptors in the visual cortex. After processing in visual cortex, part of visual signals goes to the hippocampus and makes memories. The aim of this study was evaluating effects of visual deprivation during critical period of brain development on AMPA receptor subunits expression in rats’ hippocampus.
Methods: This experimental study was done in Physiology Research Center, Kashan University of Medical Sciences at winter 2014 on male Wistar rats. Animals were divided to 2 groups (n= 36 for each) were kept in standard 12 hours light/12 hours dark condition (light reared, LR) or in complete darkness (dark reared, DR) from birth to the end of the experiments. Using reverse transcription polymerase chain reaction (RT-PCR) and Western blotting techniques respectively, expression of mRNA and protein of GluR1 and GluR2 subunits was evaluated in rats’ hippocampus at ages 2, 4 and 6 weeks in both groups. After quantification of the expressions, the data were compared by two way analysis of variance.
Results: The relative expression of GluR1 subunit decreased about 24% (P=0.004) in the hippocampus of 6 WLR rats in comparison to 2 WLR ones. The relative expression of the other AMPA receptor subunit, GluR2, also increased about 190% in the hippocampus of the 6WLR animals when compared to the 2 WLR rats (P< 0.0001). Dark rearing increased the relative expression of both subunits of AMPA receptors, GluR1 and GluR2, about 20 percent (P= 0.01) in the hippocampus of 6 WDR rats in comparison to 2 WLR animals.
Conclusion: Dark rearing of rats during critical period of brain development changes the relative expression and also arrangement of both AMPA receptor subunits, GluR1 and GluR2 in the hippocampus, age dependently.

Abstract
Background: Obesity is one of the most important problems in developed countries and cause cardiovascular diseases, diabetes and hypertension. The complex phenotype influenced by both genetic and the environment factors. One of the most important genes which is effective in this phenotype is peroxisome proliferator-activated receptor gamma (PPAR-γ). This study was carried out of investigate the association of Pro12Ala (rs1801282) polymorphism in mentioned gene with obesity in Tehran Lipid and Glucose Study (TLGS).
Methods: The present study done in September 2014 in Cellular and Molecular Endocrine Research Center, Research Institute for Endocrine Sciences, Shahid Beheshti University of Medical Sciences. For the present case-control study 239 subjects with excess weight and body mass index more than 30 kg/m2 as a case and 240 subjects with normal weight and body mass index less than 25 kg/m2 as a control were selected. The rs1801282 was proliferated, detected and genotyped using tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) method.
Results: The results indicated that there was significant association between the presence of risk allele G of rs1801282 and obesity disease in the TLGS population (P=0.000). Genotype and allelic frequencies of rs1801282 in patient and healthy group were: 55.2% and 23.8% for GG, 24.3% and 30.4% for GC, 20.5% and 45.8% for CC, 67% and 39% for G, 33% and 61% for C, respectively.
Conclusion: The results of study indicated that the presence of G allele could be increase 1.7 the risk of obesity. These differences in patient and healthy group lead us to select this marker as a genetic marker to predict the risk of obesity. There are statistical differences between the distribution of mentioned polymorphism in Tehranian population and other populations. However, replicating the study in a larger population of Tehranian people with more affected cases is suggested to generalize the results of this study.

Abstract
Background: Aberrant pre-mRNA alternative splicing is a common event in cancer cells. Many abnormally spliced RNA variants have been observed in tumor cells and they can be used as biomarkers or therapeutic targets in new drug design. Increasing our knowledge in understanding the mechanisms of alternative pre-mRNA splicing for cancer-related genes and determination of cancer specific isoforms are important for the development of new strategies in cancer therapy. The aim of this study was isoforms identification and expression of PIK3CA, FGFR3 and FGFR1 genes in bladder cancer by RNA Sequencing and Real-Time PCR.
Methods: This cross-sectional study was conducted at Urology Research Center of Sina Hospital, Tehran University of Medical Sciences, Tehran, from September 2014 to October 2016. Paired tumor and adjacent normal tissues samples were obtained from 30 bladder cancer subjects. Total RNAs were extracted from bladder tumor and normal tissues. Quantitative and qualitative examinations have been done. After quality control, fragmentation of RNAs and cDNA library construction, next-generation RNA sequencing was performed. Resulting raw data were analyzed with different bioinformatics software. Differential expression was confirmed by Real-Time PCR.
| Results: RNA sequencing results showed the number of PIK3CA (1 vs 3), FGFR3 (7 vs 6) and FGFR1 (9 vs 12) isoforms and their expression were different in bladder normal tissues in comparison to tumor tissues. Overexpression of PIK3CA gene have been observed in 42% of tumor samples but statistically was not significant. Increased FGFR3 gene (P=0.01) and decreased FGFR1 (P=0.01) expression were significant. There was an association with overexpression of FGFR3 and cigarette smoking ((P=0.037) and family history (P=0.004). |
Conclusion: RNA sequencing make possible to do the accurate assessment of transcript abundance and identification of different isoforms resulted from aberrant pre-mRNA alternative splicing, which is a crucial process for the maturation of transcripts of multi-exon genes. Regarding the differences in isoforms expression in tumor and normal tissues of bladder cancer, they have potential to be used as biomarkers and sensitive targets for cancer therapy.

Abstract
Background: Iron deficiency in the body is the main cause of anemia, and iron supplementation is probably the best option for iron deficiency and iron deficiency anemia in women and young children. This study aimed to explain the challenges of national iron supplementation in female school’s base on the perspective of the stakeholders.
Methods: This study was a qualitative study of content analysis. The data of this study were conducted by focus group discussion, semi-deep interviews with the participation of the target community of students, parents of students, school principals and school health instructors, general manager of the Office of Community Nutrition (Department of Education) includes manager, deputy and school health officer, from October 2016 to January 2017 in city of Gonabad, Iran. Participants were selected through targeted sampling and data collection continued to saturation. Data were analyzed using contractual content analysis method based on five steps of Graneheim and Lundman. Data management was done with NVivo software, version 11 (QSR International, Victoria, Australia), but data analysis and interpretation were done manually.
Results: The findings from group discussions and semi-deep interviews with stakeholders were categorized into twelve themes. The main strength, perceived in "Perceived Individual Benefits" and "Perceived Executive or Management Benefits". The main perceived weakness was "Physical Disadvantages", "Tablets Disadvantages", "Disadvantages of Programming" and "Disadvantages of the Program". The main perceived barriers was "Educational and Information Barriers", "Barriers of Pill Consumption" and "Management and Administrative Barriers". "Modifying the Executive Program", "Individual Perception Modification" and "Reform the Shape of Pills" were suggested as a corrective mechanism from participants’ view point.
Conclusion: According to the results of this study, the most important challenges of the "Schools Iron Aid National Plan" were "Educational and Information Barriers", "Administrative barriers", and "Barriers to Pill Consumption". Therefore, in order to do better, the Iron Supplementation Program requires intervention at individual, interpersonal, inter-organizational, and intra-organizational levels to provide comprehensive support for the program and, ultimately, increase program productivity.

Abstract
Background: Low-Molecular-Weight Heparin (LMWH) is recommended as the first-line treatment in patients with active cancer and venous thromboembolism (VTE), but many patients prefer to take oral anticoagulants and non-injectable forms with more reasonable price. Venous thromboembolism is a very common comorbidity in patients with cancer. Therefore, the aim of this study was to evaluate the efficacy and safety of the rivaroxaban compared with enoxaparin in patients with cancer and VTE.
Methods: This randomized clinical trial was conducted on 50 patients with non-hematologic cancer and deep vein thrombosis (DVP) or pulmonary thromboembolism (PTE) enrolled into Imam Khomeini hospital, from November 2019 to March 2020 in Ahvaz. The participants randomly assigned in two treatment groups (25 patients in each group) of rivaroxaban (15 mg every 12 hours for the first three weeks and then orally at 20 mg daily) or enoxaparin (1 mg/kg by subcutaneous injection every 12 hours) and followed for 6 months to evaluate the efficacy, complications and safety (incidence of recurrent VTE, major bleeding and deaths) of these therapies in Ahvaz.
Results: The three most common cancer diagnoses were breast (n=11, 22%), colon (n=10, 20%), and lung (n=7, 14%). Major bleeding at 6 months was only seen in one patient (4%) in the enoxaparin group and did not occur in the rivaroxaban group (P>0.05). Minor bleeding occurred in 1 patient (4%) in the rivaroxaban group and did not occur in the enoxaparin group (P>0.05). One patient in the enoxaparin group died because of fever and neutropenia. The prevalence of DVT and PTE in cancer patients was not significantly different based on patient age (P=0.154), gender (P=0.430), BMI (P=0.490), underlying disease (P=0.294), smoking (P=0.955), type of cancer (P=0.527), and metastatic cancer (P=0.280).
Conclusion: The results of this study suggest that the efficacy of rivaroxaban is not less than that of enoxaparin and therefore can be a potential option for patients with non-hematologic cancer and VTE. However, further randomized, controlled trials are needed to confirm these results.

Abstract
Background: Medical Laboratories have a great impact on patient safety and 80-90% of medical diagnoses are based on the results of laboratory tests. Medical procedures from the initial diagnostic steps such as a test or a simple injection to specialized treatment steps may be erroneous. The aim of this study was to determine the type and rate of human error, equipment, materials and procedures in all stages including before analysis, during analysis and after analysis to analyze the causes and find logical solutions to reduce of them.
Methods: This cross-sectional descriptive study was performed in a medical center in Tehran, Iran during the years 1400-1401. Data collection was considered in accordance with the instructions of the Laboratory Affairs Department of the Ministry of Health and Medical Education regarding the type of errors in the field of job description in each of the technical and non-technical sections. Data was analyzed by IBM SPSS software, version 22 (SPSS Inc., Chicago, IL, USA) software.
|
Results: During the period of study, the number of referred patients was about 45,000 and the number of tests 594,000. The total number of errors was 837. The ratio of errors to the patients was 1.9% and to the tests 0.15%. The 37 types of errors were identified and reported in this study. Of these, 11 types of errors were in the pre-analysis, 14 types during the analysis and 12 types of errors in the post-analysis stage. The frequency of errors in the three stages was 180(21.5%), 312(37.3%) and 345(41.2%), respectively that the errors rate did not have a normal distribution and a significant difference was observed (P<0.05, df=2).
Conclusion: Due to the variety of reported errors and the importance of their role in other stages of diagnosis and treatment, it is necessary that all human, equipment and process errors in all stages of laboratory analysis be carefully recorded and corrective and preventive measures be taken to minimize them.
