It has been hypothesized that maternal hyperhomocysteinemia to be associated with preeclampsia. The aims of the present study were to examine maternal serum levels of total homocysteine in preeclamptic women and its association with the severity of the disease. The study population consisted of 30 preeclamptic patients and 30 matched healthy pregnant women. Serum levels of total homocysteine were assessed using enzyme immunoassay method. Maternal serum levels of total homocysteine were significantly higher in preeclamptic group than in normal pregnant women. Women with severe preeclampsia had higher serum levels of total homocysteine than mild preeclamptic patients. Levels of total homocysteine correlated positively with systolic blood pressure values in preeclamptic women. In summary, maternal serum levels of total homocysteine were increased in preeclamptic women and hyperhomocysteinemia was associated with severity of preeclampsia.

Background: Preeclampsia complicates up to 3% of pregnancies in developing countries. Endothelial dysfunction plays an important role in pathogenesis of preeclampsia. In this study, we aim to evaluate the effect of low-dose aspirin on endothelial dysfunction in preeclamptic patients. Materials and Methods: in this triple-blind randomized clinical trial, enrolled patients were divided randomly into two groups. Acetylsalicylic acid (ASA) 80 mg or placebo will be taken daily by oral administration from the initiation of diagnosis until 2 months after delivery. Every patient's flow-mediated dilation (FMD) were evaluated at the beginning of study and 2 months after delivery with the same experienced operator at a same period of the time (3–5 pm) by high-resolution B-mode ultrasonographic. T-test or Mann–Whitney test was used in the comparison of means between the intervention and placebo groups. To compare FMD in each group, before and after the intervention, paired t-test was used. Results: Mean value of FMD in intervention (9.61 ± 5.58) and control group (9.40 ± 4.33) have no significant differences before drug consumption (P = 0.089). FMD in intervention group significantly increased after ASA consumption ([9.61 ± 5.58 vs. 13.65 ± 7.91] [P = 0.044]). Conclusion: Increase mean of FMD in intervention group shows that this supplement can improve endothelial function. PMID:28331517

This study aims to evaluate whether the Punica granatum fruit extract modulates the Angiotensin-II Type I receptor (AT1-R) and thromboxane B2 level in endothelial cells induced by plasma from preeclamptic patients. Endothelial cells were obtained from human umbilical vascular endothelial cells. At confluence, endothelial cells were divided into five groups, which included endothelial cells exposed to 2% plasma from normal pregnancy (NP), endothelial cells exposed to 2% plasma from preeclamptic patients (PP), and endothelial cells exposed to PP in the presence of ethanolic extract of Punica granatum (PP + PG) at the following three doses: 14; 28; and 56 ppm. The expression of AT1-R was observed by immunohistochemistry technique, and thromboxane B2 level was done by immunoassay technique. Plasma from PP significantly increased AT1-R expression and thromboxane B2 levels compared to cells treated by normal pregnancy plasma. The increasing of AT1-R expression significantly (P < 0.05) attenuated by high dose treatments of Punica granatum extract. Moreover, the increasing of thromboxane B2 levels significantly (P < 0.05) attenuated by lowest dose treatments of Punica granatum extract. We further concluded that Punica granatum fruit protects and inhibits the sensitivity of endothelial cells to plasma from preeclamptic patients due to inhibition of AT1-R expression (56 ppm) and reduced thromboxane B2 levels (14 ppm).

This study aims to investigate whether an ethanolic extract of Theobroma cacao bean is able to increase cell viability and decrease IL-6 and sVCAM-1 in endothelial cells induced by plasma from preeclamptic patients. Endothelial cells were obtained from human umbilical vascular endothelial cells. At confluency, endothelial cells were divided into six groups, which included control (untreated), endothelial cells exposed to plasma from normal pregnancy, endothelial cells exposed to 2% plasma from preeclamptic patients (PP), endothelial cells exposed to PP in the presence of ethanolic extract of T. cacao (PP+TC) at the following three doses: 25, 50, and 100 ppm. The analysis was performed in silico using the Hex 8.0, LigPlus and LigandScout 3.1 software. Analysis on IL-6 and sVCAM-1 levels were done by enzyme linked immunosorbent assay (ELISA). We found that seven of them could bind to the protein NFκB (catechin, leucoanthocyanidin, niacin, phenylethylamine, theobromine, theophylline, and thiamin). This increase in IL-6 was significantly (P<0.05) attenuated by both the 50 and 100 ppm treatments of T. cacao extract. Plasma from PP significantly increased sVCAM-1 levels compared to untreated cells. This increase in sVCAM-1 was significantly attenuated by all doses of the extract. In conclusion, T. cacao extract prohibits the increase in IL-6 and sVCAM-1 in endothelial cells induced by plasma from preeclamptic patients. Therefore this may provide a herbal therapy for attenuating the endothelial dysfunction found in preeclampsia.

Background: In recent decades, patient safety has become a high priority health system issue, due to the high potential of occurring adverse events in health facilities. Objectives: This study was aimed to survey patient safety culture in 2 Iranian educational hospitals. Materials and Methods: In a descriptive, cross-sectional survey, a hospital survey on patient safety culture, was used in two teaching hospitals in Yazd, Iran during 2012. Study population was comprised of the same hospitals' nurses. Stratified-random sampling method was used and distributed among a total of 340 randomly-selected nurses from different units. From all distributed questionnaires, 302 ones were answered completely and afterwards analyzed using SPSS 17. Dimensional- and item-level positive scores were used for results reporting. Additionally descriptive statistics (mean and standard deviation), independent sample t-test and ANOVA were sued for data analyzing. Results: Research findings demonstrated that both hospitals had low to average scores in all dimensions of patient safety culture. Non-punitive response to error, staffing and frequency of events reported had the lowest positive scores of patient safety dimensions with scores 15.26, 19.26, 16.65, 30 and 32.87, 31.10 respectively in Shahid Sadoughi and Shahid Rahnemoon Hospitals. Also only 29.20 and 28.80 percent of nurses in Shahid Sadoughi and Shahid Rahnemoon Hospitals, respectively, evaluated the patient safety grade of their hospital as “excellent” and “very good”. Indeed, the studied hospitals had a statistical difference in 3 dimensions of patient safety culture (frequency of events reported, organizational learning and staffing). (P ≤ 0.05) Conclusions: Our study results were indicating of the challenge of weak patient safety culture, in educational hospitals. Therefore, the issue should be integrated to all policy makers and managerial initiatives in our health system, as a top priority. PMID:24910783

Introduction. Appropriate adherence to medication is still a challenging issue for hypertensive patients. We determined adherence to antihypertensive(s) and its associated factors among 280 Iranian patients. Methods. They were recruited consecutively from private and university health centers and pharmacies in four cities. The validated Persian version of the 8-item Morisky Medication Adherence Scale (MMAS-8) was administered to measure adherence. Results. Mean (±SD) overall MMAS-8 score was 5.75 (±1.88). About half of the sample (139 cases, 49.6%) showed low adherence (MMAS-8 score < 6). There was a negative linear association between the MMAS-8 score and systolic BP (r = -0.231, P < 0.001) as well as diastolic BP (r = -0.280, P < 0.001). In linear regression model, overweight/obesity (B = -0.52, P = 0.02), previous history of admission to emergency services due to hypertensive crisis (B = -0.79, P = 0.001), and getting medication directly from drugstore without refill prescription in hand (B = -0.51, P = 0.04) were factors recognized to have statistically significant association with the MMAS-8 score. Conclusion. Antihypertensive adherence was unsatisfactory. We suggest that health care providers pay special attention and make use of the aforementioned findings in their routine visits of hypertensive patients to recognize those who are vulnerable to poor adherence.

Chronic sinusitis is a major cause of morbidity today. Regional variations in the incidence of this disease have been reported. The aim of this study was to evaluate the incidence of fungal infection as the causative agent of chronic sinusitis among Iranian patients. A cross sectional hospital based study was designed; the patients underwent paranasal sinus washing and maxillary sinus biopsy. All specimens were studied by light microscopy. Fungal culturing was employed to confirm diagnosis. The patients underwent Computed Tomography for sinus evaluation. Of 162 participants, 12 samples from patients showed fungal elements, 2 of them Aspergillus fulvous (1.2%), 9 of them Alternaria species (5.56%) and 1 of them Psilomysis (0.6%). All patients presented radiologic evidence of sinusitis, ranging from mucosal thickening to total opacity. In conclusion, results obtained showed a low prevalence of fungal sinusitis among Iranian patients with chronic sinusitis. Findings also showed that Alternaria is the most causative agent.

To study the resistance to standard dosage of clopidogrel among Iranian patients following percutaneous coronary intervention measured by platelet aggregation test. Patients undergoing percutaneous coronary intervention in Imam Hussein Medical center, Tehran, Iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. Patients received standard dosage of clopidogrel (Plavix®, Sanofi, France, 600 mg loading dose and 75 mg/day afterward). Platelet aggregation was measured using light transmission aggregometer. The response to the drug was categorized as complete resistance (platelet aggregation decreased less than 10%), intermediate resistance (platelet aggregation decreased between 10 to 30%) and complete response (platelet aggregation decreased to 30% or more). All patients were evaluated for major adverse cardio vascular events one month after the angioplasty based on MACE criteria by phone contact. Thirty-one patients with a mean age of 59 ± 13 entered the study. Sixty-five percent of patients showed complete response to clopidogrel (95% CI: 45% to 81%), 22% showed intermediate resistance (95% CI: 10-41%) and 13% showed complete resistance (95% CI: 4-30%). One month after the angioplasty, no major adverse cardiovascular event was recorded. Based on our findings, it seems that there is no major difference between Iranian population and other studies regarding the resistance to clopidogrel. Due to the limited number of participants in our study, further investigations with higher number of patients are recommended to more precisely calculate the percentage of resistance among Iranian patients.

Background: Familial Mediterranean fever (FMF) is an autosomal recessive genetic disorder characterized by recurrent episodes of self-limited fever and serosal tissues inflammation. Methods: To evaluate clinical symptoms and common genetic mutations in southwestern Iranian patients with FMF, 20 unrelated patients were enrolled in this study based on clinical criteria. A panel of 12 common MEFV gene mutations was tested Results: The most frequent clinical presentations of the patients were fever, colicky abdominal pain and arthritis. Eighteen patients responded completely to colchicine therapy. MEFV gene mutations were detected in only 40% of the patients. The most common mutation was E148Q, detected in five patients (25%). The V726A, M694V and P369S mutations were each observed in one patient. Conclusions: Although none of the 12 mutations we included in our test panel was detected in 60% of our patients, all of them had FMF symptoms and responded well to colchicine. MEFV full gene sequencing analysis in these patients may lead to finding new mutations in southwestern Iranian FMF patients which would be helpful in designing a local diagnostic kit. PMID:28367474

Background: Pre-eclampsia as a hypertensive disorder of pregnancy complicates up to 5–10% of pregnancies worldwide. Endothelial dysfunction plays an important role in the pathogenesis of pre-eclampsia. In this study, we aim to evaluate the effect of high-dose folic acid on endothelial dysfunction in pre-eclamptic patients. Materials and Methods: In this triple-blinded randomized clinical trial, the enrolled patients were divided randomly into two groups. Folic acid 5.0 mg or placebo was taken daily by oral administration from the initiation of diagnosis until 2 months after delivery by the participants. Every patient's flow-mediated dilation (FMD) was evaluated at the beginning of the study and 2 months after delivery with the same experienced operator at the same period of time (3–5 p.m.) by high-resolution B-mode ultrasonography. Potential confounding variables were included in the independent samples t-test. t-test or Mann–Whitney U-test was used in the comparison of means between the intervention and placebo groups. To compare FMD in each group, before and after the intervention, paired t-test was used. Results: Mean value of FMD in intervention (9.64 ± 5.57) and control group (9.30 ± 4.25) has no significant difference before the consumption of drugs (P > 0.05). FMD in intervention group (13.72 ± 7.89) significantly increases after daily consumption of 5 mg folic acid in comparison with control group (10.02 ± 4.81) after daily consumption of placebo (P = 0.002). Conclusion: Increased mean of FMD in intervention group shows that this supplement can improve endothelial function and can be significantly affected by maternal blood pressure during pregnancy and some endothelium-dependent disease such as pre-eclampsia and its associated adverse outcomes.

We tried to evaluate prevalence and characteristics of Iranian HIV infected patients with retinitis due to opportunistic infections. In this cross sectional study, we evaluated 106 HIV infected patients via indirect ophthalmoscopy and slit lamp examination by 90 lens to find retinitis cases. General information and results of ophthalmologic examination were analyzed. Prevalence of retinitis due to opportunistic infections was 6.6%: cytomegalovirus (CMV) retinitis 1.88%, toxoplasmosis retinochoroiditis 1.88% and tuberculosis chorioretinitis 2.83%. CD4 count was higher than 50 cell/µlit in both cases with CMV retinitis. Along with increasing survival in the HIV infected patients, the prevalence of complications such as ocular manifestation due to opportunistic infections are increasing and must be more considered.

Pre-eclampsia (PE) remains the leading cause of pregnancy-associated mortality and morbidity, urging the need for a better understanding of its aetiology and pathophysiological progression. A key characteristic of PE is a systemic, exaggerated, inflammatory condition involving abnormal cytokine levels in serum, altered immune cell phenotype and Th1/Th2-type immunological imbalance. However, it is unknown how this heightened inflammatory condition manifests. We previously reported increased expression of the lipopolysaccharide receptor, Toll-like receptor 4 (TLR4), on monocytes from PE patients compared with normotensive, pregnant patients (NP). This upregulation of TLR4 on PE monocytes was accompanied by a hyper-responsiveness to bacterial TLR4 ligands. To determine whether non-microbial, endogenous TLR4 ligands also activate monocytes from PE patients, we investigated the expression of host-derived TLR4 ligands and the response of monocytes to these endogenous ligands. Plasma levels of fibrinogen - but not fibronectin or heparan sulphate - were higher in PE patients than in NP. Exposure to fibrinogen was associated with significantly increased production of inflammatory cytokines by monocytes from PE patients. Interestingly, this effect was not observed with NP monocytes. Our findings suggest that the fibrinogen-TLR4 axis might play an important role in the atypical activation of monocytes observed in PE patients that may contribute to the exaggerated inflammatory condition.

A multidisciplinary approach to the preterm delivery of a preeclamptic parturient with severe left ventricular (LV) noncompaction and pulmonary hypertension using transesophageal echocardiography (TEE) as a monitor of hemodynamic status in lieu of a pulmonary artery catheter during general anesthesia for Cesarean section is presented. This case adds to the available literature on LV noncompaction with pulmonary hypertension in preeclamptic parturients, and addresses the anesthetic concerns and approaches to management using echocardiography in these highly complex patients.

To compare morphological changes in the umbilical cords from chronic hypertensive and preeclamptic patients having normal or pathological umbilical artery Doppler ultrasonographic results. Umbilical cords from 34 normotensive, 31 chronic hypertensive and 70 preeclamptic women with normal and abnormal Doppler flow velocity waveforms (FVW) at 35-40 gestational weeks were studied. Morphological changes in the umbilical cords were examined on formalin-fixed, paraffin-embedded sections. The total umbilical cord area, total vessel area, and wall thickness of umbilical vessels were measured in systematic random samples using unbiased stereology methods. An ANOVA test was used for statistical analysis. In the chronic hypertensive and preeclamptic groups with normal Doppler FVW, the thickness of the umbilical cord vessels remained nearly constant, whereas both the total area and the lumen area were reduced. These changes correlate with the histopathological findings, suggesting a mainly vasoconstrictive effect. By contrast, analysis of the preeclamptic group with pathologic Doppler FVW showed a comparable reduction of all parameters of the umbilical cord. Histopathological findings were related to smaller, contracted smooth muscle cells of the vessel wall, which is suggestive of a predominant hypoplastic mechanism. As a result of reduced uteroplacental perfusion, fetal hypoxia and intrauterine growth retardation become unavoidable in preeclampsia. The histopathological changes in the umbilical cord between the chronic hypertensive and preeclamptic patients depend on the Doppler results. In conclusion, the umbilical artery Doppler FVW indices provide good values for predicting intrauterine growth retardation in preeclamptic patients.
The leading cause of pregnancy-associated mortality and morbidity is pre-eclampsia (PE). Although information regarding the etiology of this disease is scant, its pathophysiology is characterized by abnormal placentation, endothelial dysfunction as well as an exaggerated inflammatory response. Clinical evidence also indicates that the abundance of many immune cells at the feto-maternal interface and in the circulation of PE patients is abnormal, when compared with normal pregnant (NP) controls. In addition, the phenotype and function of some of these cells is altered. To further characterize the systemic effects of PE on circulating cells, we analyzed monocytic subpopulations in NP and PE patients by flow cytometry. We found that non-classical CD14lowCD16+ monocytes are significantly increased in women with PE and they display irregular expression of several chemokine receptors and antigen presentation molecules. The most striking phenotypic difference among the cell surface molecules was the marked upregulation of TLR4 expression, where both CD14highCD16+ and CD14lowCD16+ monocytes demonstrated higher levels than their NP counterparts. Stimulation of PE monocytes with TLR ligands resulted in profound secretion of various cytokines in comparison with NP controls. These data suggest that PE monocytes are hyper-responsive to TLR ligands and this may contribute to exacerbation of the disease. PMID:22848746

Background Although several studies have been performed on risk factors and natural course of NASH, it seems that NASH tends to be more than a disease confined to strict boundaries. The objective of this study was to assess the clinical and paraclinical features and risk factors for non-alcoholic steatohepatitis (NASH) patients in an Iranian population Methods Patients with histologically confirmed NASH who had elevated liver aminotransaminases, negative serologic markers of viral or autoimmune hepatitis and no findings in favor of metabolic liver disease were enrolled. A careful history was taken regarding alcohol intake. Results 53 patients consisting of 32 male and 21 female entered the study. The mean age was 37.8 ± 11.3 years. Twenty-six patients (55.3%) were overweight, 15 (31.9%) obese, 40 (75.5%) dyslipidemic, and three patients (5.7%) were diabetic. Liver biopsy showed mild steatosis in 35.7%, moderate steatosis in 53.6%, and severe forms in 10.7%. In 80.2% of patients, portal inflammation was present, and 9.4% had cirrhosis. The amount of increase in liver enzymes bore no relationship with fibrosis, portal inflammation, and degree of steatosis. Conclusions The patients in our study showed a male predominancy and were somewhat younger than other studies. PMID:14561231

Introduction Health is an exclusive and subjective phenomenon, and one of the most important situations with regard to perception of health, arises when patients suffer from a chronic disease. This study was conducted within the qualitative research framework and aimed to explore the meanings of health as perceived by a group of Iranian diabetic patients. Methods A descriptive qualitative analysis design was used. Data were collected through semi-structured interviews with 20 participants among diabetic patients, who were admitted to the diabetes care centre of Tohid Hospital of the Kurdistan University of Medical Sciences, Sanandaj, Iran during a ten-month period in 2014. Interviews were transcribed and analysed through conventional content analysis. Results Based on the findings of the study, three major health-related themes emerged: 1) the syndrome of the healthy body and the happy heart (physical well-being vivacity, satisfaction, and calmness of the mind), 2) life without compulsory limitations (lack of dietary limitations, No activity limitations, lack of social limitations), and 3) exalted spirituality (satisfying self and others, trusting God, remembering God). Conclusion Health care providers should consider the meaning of health in special groups, chiefly in patients with chronic diseases. It facilitates the development of appropriate programmes to improve desirable health levels among diabetic patients. PMID:27790342

Background: Occult hepatitis C virus (HCV) infection is defined as the presence of HCV-RNA in liver or peripheral blood mononuclear cells (PBMCs) in the absence of detectable hepatitis C antibody (anti-HCV) or HCV-RNA in the serum. Low concentrations of HCV-RNA may be detected in PBMCs of hemodialysis (HD) patients and this could have a great impact on the management of HD patients. Objectives: The aim of this study was to detect the occult HCV infection in Iranian HD patients. Patients and Methods: A total of 70 anti-HCV negative HD patients from three dialysis units in Tehran, Iran were included in this study. In these cases, presence of HCV-RNA in plasma samples was tested by reverse transcriptase-nested polymerase chain reaction (RT-nested PCR). In cases with negative anti-HCV and plasma HCV-RNA, genomic HCV-RNA was checked in PBMC specimens by RT-nested PCR. Results: Seventy anti-HCV negative HD patients were enrolled in the study. 32.85% and 1.43% of cases had elevated levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) respectively. 7.14% of patients had elevated levels of both ALT and AST. HCV-RNA was negative in plasma samples of all anti-HCV negative HD subjects. The genomic HCV-RNA was not detected in any PBMC samples of HD cases with negative anti-HCV and plasma HCV-RNA. Conclusions: Occult HCV infection was not detected in our HD patients despite of elevated levels of liver enzymes in some participants. Further studies involving larger number of HD patients are required to elucidate the rate of occult HCV infection in HD cases. PMID:26457258

Alterations of trace element concentrations adversely affect biological processes and could promote carcinogenesis. Only a few studies have investigated the degree of changes in copper and zinc levels in colorectal cancer (CRC). The aim of the present study was to compare the serum copper (Cu) and zinc (Zn) concentrations in patients with CRC from Iran with those of healthy subjects. Cu and Zn concentrations in the serum of 119 cancer patients and 128 healthy individuals were measured by atomic absorption spectrometry. We found a significant decrease in the total mean serum Cu and Zn concentrations in CRC patients as compared with the control group (137.5 ± 122.38 vs. 160.68 ± 45.12 μg/dl and 81.04 ± 52.05 vs. 141.64 ± 51.75, respectively). However, the serum Cu/Zn ratio in the patient group was significantly higher than that measured in the control group (p = 0.00). There was no significant difference in the mean values of serum Cu and Zn concentrations between young (<60 years) and elderly (≥60 years) patients. However, the Cu/Zn ratio in <60-year cases was significantly higher than that in ≥60-year age group (p < 0.05). In addition, mean serum Cu level in normal weight patients was significantly higher than that in overweight/obese cases (132.31 ± 87.43 vs. 103.81 ± 53.72 μg/dl, respectively) (p < 0.05). There was no difference in mean serum Cu and Zn concentrations in patients stratified by the site, stage, or differentiation grade of tumors. Our findings suggest that imbalance in Cu and Zn trace element level is associated with CRC and might play an important role in cancer development among Iranian patients.

Posterior reversible encephalopathy syndrome (PRES) is a neurological syndrome associated with a number of conditions including preeclampsia. It is characterized by seizures, alteration of consciousness, visual disturbances, and symmetric white matter abnormalities, typically in the posterior parietooccipital regions of the cerebral hemispheres, at computed tomography (CT) and magnetic resonance (MRI). We report three new cases of PRES in preeclamptic patients and describe the management of these patients. We present a brief review of other cases in the literature, with particular attention to the anesthetic management. PMID:25506009

In this study, by examining 5-HT7 receptor expression in placentae from pre-eclamptic and normal pregnancies, we aimed to discover a new step of pathophysiological cascade for preeclampsia. Patients whose blood pressure over the 140/90 mmHg were included when study after 20 weeks of gestation. 5-HT7 receptor expression was investigated on the placentae obtained after birth by real time PCR (RT-PCR) analysis. Pre-natal-post-natal, systolic-diastolic blood pressure values, proteinuria and renal function indicators as BUN and creatinine levels of pre-eclamptic pregnant women were higher than the healthy group. Similarly, 5-HT7 receptor expression determined in healthy placentae increased 8-fold in pre-eclamptic women. This study, for the first time we showed 5-HT7 receptor expression in normal placenta and increased expression in pre-eclamptic placenta.

Objective: The purpose of the study was to examine relationships between death anxiety and quality of life (QOL) parameters of patients with cancer in the Iranian sociocultural context. Methods: A descriptive, correlational methodology was used. The sample included 330 patients. Demographics, health information, religious behaviors, death anxiety, and QOL data were collected. Results: Overall death anxiety levels were moderate with satisfactory overall QOL. Death anxiety was predictive of lowered QOL. Female patients had lower QOL and higher death anxiety compared to men Conclusions: Findings support that higher death anxiety negatively impacts QOL in an Iranian sample with cancer. Alleviation of existential concerns in vulnerable patients may palliate mental health distress associated with facing cancer and its challenging treatments. PMID:27981157

Introduction: Investigation of supportive care needs of cancer patients is important to implement any supportive care programs. There is no relevant studies investigated supportive care needs of Iranian cancer patients and factors affecting such needs. So, the aims of present study were to determine the unmet supportive care needs of Iranian cancer patients and its predictive factors. Methods: In this descriptive- correlational study 274 cancer patients in one referral medical center in North West of Iran participated. For data collection, demographic and cancer related information checklist and Supportive Care Needs Survey (SCNS) was used. Logistic regression was used for data analysis of un-adjusted and adjusted Odds Ratios (ORs) for patients needs and analysis of variables of study based on Backward LR procedure SPSS Ver.13. Results: More than fifty percent of participants reported unmet needs in 18 items of SCNS. Most frequent unmet needs were related to health system and information domains and most meet needs were related to sexuality and psychological domains. The result of logistic regression identified predictors of each domain of supportive care needs. The variable such as sex, age and living situation were most important predictors of unmet needs. Conclusion: The results showed that Iranian cancer patients have many supportive care needs in different domains. In general female cancer patients are at risk of more unmet supportive care needs. So, health care professionals should be more sensitive to fulfillment of supportive care needs of female. PMID:28032075

Background: Consideration of patient autonomy is an essential element in individualized, patient-centered, ethical care. Internal and external factors associated with patient autonomy are related to culture and it is not clear what they are in Iran. The aim of this study was to explore contextual factors affecting the autonomy of patients in Iranian hospitals. Materials and Methods: This was a qualitative study using conventional content analysis methods. Thirty-four participants (23 patients, 9 nurses, and 2 doctors) from three Iranian teaching hospitals, selected using purposive sampling, participated in semi-structured interviews. Unstructured observation and filed notes were other methods for data collection. The data were subjected to qualitative content analysis and analyzed using the MAXQDA-10 software. Results: Five categories and sixteen subcategories were identified. The five main categories related to patient autonomy were: Intrapersonal factors, physical health status, supportive family and friends, communication style, and organizational constraints. Conclusions: In summary, this study uncovered contextual factors that the care team, managers, and planners in the health field should target in order to improve patient autonomy in Iranian hospitals.

Background: There are important differences regarding cancer disclosure in various geographical populations (Europeans, Western Asia, Eastern Asia), depending on multiple sociocultural factors, and therefore, there is no standard protocol on this issue, especially in Iran. Objectives: To evaluate the amount of information that Iranian patients have and their preference for the disclosure of the cancer diagnosis. Patients and Methods: In this cross sectional descriptive research, patients admitted in the oncology departments of 3 referral medical centers, Imam Hussein, Shohada-e-Tajrish and Modarres, in Tehran, from March 2007 to April 2008, were questioned about their awareness and knowledge regarding their diagnosis. Two different structured questionnaires were designed for the people who know and who didn't know their diagnosis. For the former, the survey concerned their psychological reactions to their situations, whether they would prefer to know about their diagnosis and by whom they are preferred to be informed .For the latter, the questionnaire included their preference whether to know the diagnosis and their current emotional state. Descriptive statistics and chi square test was applied to analyze gathering Data, using SPSS version 14. Results: 60.3% of the patients knew their diagnosis. Among the subjects who did not know their diagnosis, 88% preferred to be more informed about their diagnosis and 68% had some psychological reaction to their situations. Among the subjects who knew their diagnosis, 92.1 % preferred to know their diagnosis, 73.6% preferred to be informed directly by their physicians. Following the diagnostic disclosure, 81.5% reported that they had felt nervous, anxious and worried. Conclusions: The majority of Iranian patients with malignancy want to know the truth and they prefer to be informed directly by their doctors. PMID:26834800

Preeclampsia is a multisystem disorder unique to human pregnancy, characterized by abnormal placentation. Although its causes remain unclear, it is known that the expression of several transporters is altered. Transient receptor potential vanilloid 1 (TRPV-1) is a nonselective cation channel, present in human placenta. Here, we evaluated the expression of TRPV-1 in preeclamptic placentas. We observed a deregulation in TRPV-1 expression in these placentas which may explain the impaired Ca(2+) homeostasis found in preeclampsia.

Occult hepatitis C virus infection (OCI) is a new pathological form of chronic hepatitis virus (HCV) infection characterized by the presence of HCV RNA in liver biopsy and/or peripheral blood mononuclear cell (PBMC) specimens and the absence of HCV RNA and anti-HCV antibodies (Abs) in plasma samples. β-thalassemia major is a hereditary recessive blood disease with deficiency in the hemoglobin beta chain. Thalassemic patients need blood transfusion therapy; repeated blood transfusion increases the risk of viral blood-borne infection. The aim of this study was to determine the prevalence of OCI in Iranian patients with β-thalassemia major. From February 2015 to November 2015, a total of 147 Iranian patients with β-thalassemia major were enrolled in this cross-sectional study. After extraction of viral RNA from the plasma and PBMC samples, HCV genomic RNA in the specimens was amplified by RT-nested PCR using primers from the 5'-UTR. The HCV genotypes of the positive specimens were tested using the RFLP assay. To confirm the HCV genotypes, the 5'-UTR fragment was amplified and cloned into the pJET1.2/blunt cloning vector and then sequenced. Out of 147 patients, 106 (72.1 %) were negative for anti-HCV Abs and HCV RNA. HCV RNA was found in PBMC specimens of six (5.7 %) patients, from a total of 106 patients with undetectable plasma HCV RNA and anti-HCV Abs. Therefore, six out of 106 patients had OCI. HCV genotyping revealed that three patients were infected with HCV subtype 1b, two patients were infected with HCV subtype 3a, and one patient was infected with HCV subtype 1a. These results revealed that Iranian patients with beta-thalassemia major might have OCI. Therefore, it seems that the design of a study to identify this infection in patients with β-thalassemia major would provide valuable information.

Occult hepatitis C virus (HCV) infection is a new form of chronic HCV infection described by the presence of the genomic HCV-RNA in liver biopsy and/or peripheral blood mononuclear cell (PBMC) samples, and undetectable levels or absence of HCV-RNA and in the absence or presence of anti HCV antibodies in the plasma specimens. The aim of the present study was to evaluate the occurrence of occult HCV infection (OCI) among Iranian subjects infected with human immunodeficiency virus (HIV) using RT-nested PCR. From March 2014 until April 2015, 109 Iranian patients with established HIV infection were enrolled in this cross-sectional study. After extraction of viral RNA from the plasma and PBMC samples, HCV-RNA status was examined by RT-nested PCR using primers from the 5'-NTR. HCV genotyping was conducted using RFLP analysis. For the confirmation of HCV genotyping by RFLP method, the PCR products were sequenced. Of the 109 patients, 50 were positive for antibodies against HCV. The HCV-RNA was detected in PBMC specimens in 6 (10.2%) out of the total 59 patients negative for anti-HCV Abs and undetectable plasma HCV-RNA and also from 4 (8.0%) out of the total 50 patients positive for anti-HCV Abs and undetectable plasma HCV-RNA. HCV genotyping analysis showed that 6 (60.0%) patients were infected with HCV subtype 3a, 3 (30.0%) were infected with HCV subtype 1a and 1 (10.0%) patient was infected with HCV subtype 1b. This study revealed the incidence of OCI (9.2%) in HIV-infected Iranian patients. Hence, designing prospective studies focusing on the detection of OCI in these patients would provide more information. J. Med. Virol. 88:1960-1966, 2016. © 2016 Wiley Periodicals, Inc.

Background: Leisure time is one of the most important aspects of life, especially for people with chronic diseases. The concept and types of leisure have frequently been evaluated in different socio-cultural populations. The aim of this study was to identify the nature of leisure activities among a sample of Iranian patients with multiple sclerosis (MS) and classify the identified types of activities in the context of Iranian culture. Methods: In this qualitative study, semi-structured interview was applied to gather data from 34 MS patients that were selected through purposive sampling. The interviews were continued up to the point of saturation. Content analysis was used to explore experiences of the interviewees regarding their leisure activities. Results: Six categories of leisure activities were extracted for the studied patients with MS i.e.physical, social, individual, art/cultural, educational and spiritual/religious. Conclusion: The results represented the range and heterogeneity of leisure activities amongst the MS patients. Considering participation in spiritual/religious and social activities as leisure time undertaking might reflect cultural diversity in the perception and use of time for recreation. For mental health promotion purposes, paying special attention to the types of activities that people of different socio-cultural background choose for their refreshment could help health care providers in giving tailored advice for patients with MS and other chronic debilitating disease.

Abstract Introduction Gender identity disorders (GID) are heterogeneous disorders that may be influenced by culture and social norms. Aim The aim of this study was to determine masculine and feminine gender roles in a group of Iranian patients with GID and compare these roles with two control groups. Methods Twelve male‐to‐female (MF) and 27 female‐to‐male (FM) individuals with GID referred to Tehran Psychiatric Institute in Tehran, I. R. Iran were evaluated by self‐report inventories and were compared with two groups of healthy controls (81 men and 89 women). Diagnoses were established based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM‐IV) criteria. Data analysis was done using analysis of variance and chi‐squared test. Main Outcome Measures Masculine and feminine gender roles were assessed by two questionnaires: (i) Gender‐Masculine (GM) and Gender‐Feminine (GF) scales derived from the Minnesota Multiphasic Inventory‐2 (MMPI‐2); (ii) Bem Sex Role Inventory (BSRI). Results In the scales of masculinity, MF‐GID individuals scored as male controls, but lower than female controls. FM‐GID individuals scored similar to female controls and higher than male controls. In femininity scales, MF‐GID individuals and control women seemed similar, and both scored higher than the other groups. FM‐GID persons were considered less feminine than both controls in the GF scale of MMPI‐2, but not in the BSRI. In both scales, FM‐GID persons had higher scores than control women and MF‐GID individuals. Conclusion Iranian FM‐GID individuals were less feminine than normal men. However, MF‐GID individuals were similar to normal women or more feminine. Cultural considerations remain to be investigated. Alavi K, Eftekhar M and Jalali Nadoushan AH.

Designing newer drugs, vaccines, and diagnostic techniques is dependent on better understanding of M. tuberculosis virulence mechanism. In this study the prevalence of pcaA gene was determined in M. tuberculosis strains typed by spoligotyping. The associated risk factors among patients with different nationalities residing in Iran were also determined. The isolated M. tuberculosis strains have been characterized by performing susceptibility tests against four first-line antituberculosis drugs and were then subjected to spoligotyping characterization. PCR was used for detection of pcaA gene and its nucleotide sequence was also determined. Spoligotyping of M. tuberculosis strains resulted in 140 different patterns. One hundred twenty two (87.1%) of these spoligotype isolates were unique and reported for the first time. The remaining18 (12.8%) spoligotype patterns were previously reported from other geographical regions of the world. Haarlem family was most prevalent than other genotype. Antibiotic resistances were higher in those isolated from the Iranian patients. The pcaA gene was detected in M. tuberculosis clinical isolates but not in saprophyte strains such as M. kansasi. The results showed that, spread of M. tuberculosis strains belonging to the Beijing family among Iranian patients has to be considered seriously. This study confirmed the widespread existence of pcaA gene in almost all the clinical isolates. It is also important to undertake studies to identify which factors are the most significant to consider in tuberculosis control program. PMID:24031364

Background: Tay-Sachs disease (TSD), or GM2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase A (HEXA), resulting in lysosomal accumulation of GM2 ganglioside. The aim of this study was to identify the TSD-causing mutations in an Iranian population. Methods: In this study, we examined 31 patients for TSD-causing mutations using PCR, followed by restriction enzyme digestion. Results: Molecular genetics analysis of DNA from 23 patients of TSD revealed mutations that has been previously reported, including four-base duplications c.1274_1277dupTATC in exon 11 and IVS2+1G>A, deletion TTAGGCAAGGGC in exon 10 as well as a few novel mutations, including C331G, which altered Gln>Glu in HEXB, A>G, T>C, and p.R510X in exon 14, which predicted a termination codon or nonsense mutation. Conclusion: In conclusion, with the discovery of these novel mutations, the genotypic spectrum of Iranian patients with TSD disease has been extended and could facilitate definition of disease-related mutations.

Background Diabetes mellitus is one of the most challenging and burdensome chronic diseases of the 21st century and More than 1% of the Iranian urban population older than 20 years develops Type 2 diabetes each year. Living with diabetes mellitus has been described as a dynamic personal transitional adaptation, based on restructuring of the illness perceived experience and management of the self. Adaptation to Type 2 Diabetes mellitus is an integral part of diabetes care. This study explored the experiences of facilitators and barriers adaptation to Type 2 Diabetes by Iranian patients. Methods This study was conducted by using qualitative content analysis. Data were collected via in-depth, semi-structured and face to face interviews with 15 patients with type2 diabetes. Results Three themes emerged from collected data, including a) individual context with Beliefs, personal background, and previous experience subthemes. b) supportive system with Family, Society and Health organizations subthemes and c) self-comparison with comparison with other diabetes and comparison with other diseases subthemes. Conclusions Identifying and managing Facilitators and Barriers adaptation to Type 2 Diabetes mellitus are an integral part of diabetes care. This study provides a better understanding of the factors from perspective of patients and it can be utilized by health care providers to adapt their health care and education contents to better meet the needs of people with diabetes.

Background Geographic Tongue is a benign disorder involving the dorsal surface of the tongue characterized by depapillated areas with leading and folded edges in yellowish or grayish white color and sometimes with unclear borders. Many studies have reported a relationship between such condition and different risk factors. This study aimed to investigate the prevalence rate and the risk factors of geographic tongue in the patients referring to the Department of Oral Medicine of Zahedan Dental School, in 2012. Methods: Using Poisson regression model, 2000 patients referred to the Department were selected for this cross-sectional study. Data collection method included an investigation into the medical history as well as doing intraoral examinations. Using SPSS 17 software and Chi-square statistical test, the collected data were analyzed. Result: Among the 2000 patients selected, 7.8% (156 persons) suffered from geographic tongue. The results of our study show that there is a significant relationship between the occurrence of geographic tongue and a history of allergy and fissured tongue (P<0.001). There was no significant statistical relationship between the occurrence of geographic tongue and gender, smoking and medication. Conclusion: The geographic tongue is more frequently in the patients suffering from atopy or allergy as well as the patients with fissured tongue. PMID:23515238

This study investigated the social capital of Iranian patients living with acquired immune deficiency syndrome (AIDS) and the associated factors. In a cross-sectional study the Integrated Social Capital Questionnaire was filled by a sequential sample of 300 patients visiting a referral counselling centre in Tehran. The patients' social capital scores were around 50% in the trust, social cohesion, collective action and cooperation and political empowerment domains. The groups and networks membership domain scored the lowest (27.1%). In regression analysis, employment status was significantly associated with groups and networks membership; age, marital status and financial status were associated with collective action and cooperation; period of disease awareness and marital status affected social cohesion and inclusion; and having risky behaviour affected empowerment and political action. Efforts are needed to enhance the social capital of those patients living with AIDS who are younger, unemployed, divorced/widowed, with risky behaviours and shorter disease awareness.
Background Highly competitive market in the private hospital industry has caused increasing pressure on them to provide services with higher quality. The aim of this study was to determine the different dimensions of the service quality in the private hospitals of Iran and evaluating the service quality from the patients' perspective. Methods A cross-sectional study was conducted between October and November 2010 in Tehran, Iran. The study sample was composed of 983 patients randomly selected from 8 private general hospitals. The study questionnaire was the SERVQUAL questionnaire, consisting of 21 items in service quality dimensions. Results The result of factor analysis revealed 3 factors, explaining 69% of the total variance. The total mean score of patients' expectation and perception was 4.91(SD = 0.2) and 4.02(SD = 0.6), respectively. The highest expectation and perception related to the tangibles dimension and the lowest expectation and perception related to the empathy dimension. The differences between perception and expectation were significant (p < 0.001). There was a significant difference between the expectations scores based on gender, education level, and previous hospitalization in that same hospital. Also, there was a significant difference between the perception scores based on insurance coverage, average length of stay, and patients' health conditions on discharge. Conclusion The results showed that SERVQUAL is a valid, reliable, and flexible instrument to monitor and measure the quality of the services in private hospitals of Iran. Our findings clarified the importance of creating a strong relationship between patients and the hospital practitioners/personnel and the need for hospital staff to be responsive, credible, and empathetic when dealing with patients.

Background: Autoimmune thyroid diseases (ATDs) are the most common endocrine diseases which result in rheumatologic manifestations. Some studies have shown association between rheumatologic disorders and ATDs. Thus, the aim of this study was to assess the frequency of rheumatologic manifestations in patients with ATDs. Materials and Methods: In this cross-sectional descriptive study during 2010 to 2011, 65 patients with ATDs referred to the Rheumatology clinic of 5 Azar Hospital in Gorgan (North of Iran) were studied via systematic random sampling and patients with positive antithyroid peroxides (anti-TPO) were included in the study. These patients were examined by a rheumatologist for diagnosis of rheumatologic manifestations and tested for serum levels of TSH, Free T3 and T4, Anti-Nuclear Antibodies (ANAs) and Rheumatoid Factor (RF). SPSS software (version 16) and descriptive statistics were used for data analysis. Results: Nine males (14.8%) and 56 females (86.2%) with mean age of 38.81±1.44 years were studied. Overall, Rheumatologic manifestations were seen in 86.2 % (n=56). In this study, the most frequent rheumatologic manifestations were Carpal Tunnel Syndrome (36.1%) and Osteoarthritis (23%). Reynaud’s phenomenon (RP) (10.7%), Discopathy (8.9%), Fibromyalgia (5.3%), Myopathy (3.6%), Rheumatoid arthritis (3.6%) and trigger finger (3.6%) were other manifestations, respectively. Conclusion: In this region, there is a high frequency of rheumatologic manifestations in patients with ATDs. Thus, initial evaluation and regular checkings are recommended. PMID:25478383

Background: The PIWI-interacting RNA (piRNA) pathway has an essential role in transposon silencing, meiosis progression, spermatogenesis, and germline maintenance. HIWI genes are critical for piRNA biogenesis and function. Therefore, polymorphisms in HIWI genes contribute to spermatogenesis defects and can be considered as risk factors for male infertility. The aim of the present study was to investigate the association between the HIWI2 gene rs508485 polymorphism and non-obstructive azoospermia. Methods: A total of 121 Iranian men with idiopathic azoospermia and 100 fertile controls were genotyped for HIWI2 rs508485 (T>C) polymorphism using Tetra-ARMS PCR. The presence of eight sequence-tagged site (STS) markers from the Y chromosome AZF region was also investigated by Multiplex PCR (M-PCR). Results: Thirteen (10.74%) patients showed Y chromosome microdeletions and therefore were excluded from the study. rs508485 in the 3’UTR of HIWI2 was associated with increased risk of azoospermia in our studied population with a P-value of 0.035 and odds ratio of 2.00 (CI 95%: 1.04-3.86). Conclusions: We provide evidence for an association between genetic variation in the HIWI2 gene involved in the piRNA pathway and idiopathic non-obstructive azoospermia in Iranian patients. Therefore, piRNA pathway gene variants can be considered as risk factors for male infertility. PMID:28367472

Periodic fever syndromes are a group of diseases characterized by episodes of fever with healthy intervals between febrile episodes. In the first part of this paper, we presented a guideline for approaching patients with periodic fever and reviewed two common disorders with periodic fever in Iranian patients including familial Mediterranean fever (FMF) and periodic fever syndromes except for periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA). In this part, we review other autoinflammatory disorders including hyper IgD, tumor necrosis factor receptor–associated periodic syndrome (TRAPS), cryopyrin associated periodic syndromes, autoinflammatory bone disorders and some other rare autoinflammatory disorders such as Sweet’s and Blau syndromes. In cryopyrin associated periodic syndromes group, we discussed chronic infantile neurologic cutaneous and articular (CINCA) syndrome, Muckle-Wells syndrome and familial cold autoinflammatory syndrome. Autoinflammatory bone disorders are categorized to monogenic disorders such as pyogenic arthritis, pyoderma ;gangraenosum and acne (PAPA) syndrome, the deficiency of interleukine-1 receptor antagonist (DIRA) and Majeed syndrome and polygenic background or sporadic group such as chronic recurrent multifocal osteomyelitis (CRMO) or synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome are classified in sporadic group. Other autoinflammatory syndromes are rare causes of periodic fever in Iranian system registry. PMID:25562014

Patient advocacy is an inherent component of professional nursing ethics; in other words, nurses' enough knowledge would be essential to gain a positive attitude towards nursing advocacy. Using a descriptive-analytic design, this study aimed to assess the correlation between nurses' perception and attitudes towards patient advocacy, amongst 385 nurses in Kerman, Iran; hence, a three-part questionnaire was applied: part I, a demographic data sheet, part II, attitude measuring instrument, and part III, perception measuring instrument in nursing advocacy. The results implied that fairly positive attitudes and perception were found amongst the participants, and nurses' attitudes, in general, were positively correlated to their perception toward nursing advocacy. This means that with an improvement in perception, the attitude would also improve. In addition to our findings, it seems that these nurses needed more advocacy educational programs and support from responsible employers. PMID:23326680

The prevalence and pattern of ankylosing spondylitis (AS) can vary from country to country, according to genetic and environmental factors. This study aims to analyze the patterns of disease in a population of Iranian patients with AS. We performed a prospective study (2002-2007) analyzing 98 patients with diagnosis of AS according to the modified New York criteria. Selected patients underwent complete clinical (initial symptom, axial and peripheral involvement, heel enthesitis, extra-articular manifestations) and radiological (sacroiliac, lumbar, thoracic, and cervical spine) investigations, and these data were compared with sex, age at onset, and HLA-B27. There was predominance of men (71.4%), adult onset (>16 years, 90.8%), and positive HLA-B27 (73.4%). Family history of AS was noted in 14.3% of the patients. The predominant initial symptoms were inflammatory low back pain (44.2%). Radiological findings included syndesmophytes in 34.7% and "bamboo spine" in 16.3% of patients. Acute anterior uveitis was noted in 44.9% of patients. Male sex was associated with involvement of shoulder (P = 0.001). Female sex and juvenile-onset AS were associated with extra-articular involvement. Positive HLA-B27 was associated with hip involvement (P = 0.042) and adult-onset AS (P = 0.035). Analysis of the patterns of disease in this population of 98 southern Iranian patients with AS revealed that female sex and juvenile-onset AS were associated with extensive extra-axial involvement; and HLA-B27 was associated with hip involvement.

After diagnosis of cancer, many patients show more inclination towards religion and religious activities. This qualitative study using semi-structured interviews explored the perspectives and experiences of 17 Iranian cancer patients and their families regarding the role of religion in their adaptation to cancer in one of the hospitals in Tehran and a charity institute. The content analysis identified two themes: "religious beliefs "(illness as God's will, being cured by God's will, belief in God's supportiveness, having faith in God as a relieving factor, and hope in divine healing) and "relationship with God during the illness." In general, relationship with God and religious beliefs had a positive effect on the patients adapting to their condition, without negative consequences such as stopping their treatment process and just waiting to be cured by God. Thus a strengthening of such beliefs, as a coping factor, could be recommended through religious counseling.

Background: Sarcoidosis is a multisystem inflammatory disease of unknown origin with characterization of small granulomas. Angiotensin-converting enzyme (ACE) is a pathophysiologic marker of sarcoidosis. We present the ACE insertion/deletion (I/D) polymorphism in correlation with serum ACE level in Iranian patients with sarcoidosis. Methods: From Jan 2014 to Jan 2015, 102 Iranian patients who histopathologically diagnosed for sarcoidosis and 192 healthy age and sex-matched controls were recruited. PCR was used for detection of I/D polymorphism in ACE gene. Results: Frequency of II/ID/DD genotype in sarcoidosis disease was 17%, 35.5%, and 47.1%, respectively. The frequency of D allele was 0.65. A significant association between I/D genotypes and mean of sACE level was seen (DD=85.2±22.9, P<0.001). More frequent genotype in sarcoidosis patients was DD (47%), ID genotype (45.9%) was found more in controls. Logistic regression analysis adjusting age and sex showed that ID to II (OR=0.35, 95%CI=0.17–0.73, P=0.005) and DD to II (OR=2.11, 95%CI=0.98–4.54, P=0.05) could be considered as a predictor factor for the disease activity. No significant model for men in sarcoidosis group was seen, while women with II/ID were associated with a reduced risk for the disease. Conclusion: Although more regional studies with appropriate statistical scale must be done to provide a better diagnosis and prognostic tool for this disease, this study demonstrates that ID and DD genotype could be predictive factors for sarcoidosis.

Background: Pragmatics is appropriate use of language across a variety of social contexts that provides accurate interpretation of intentions. The occurrence of the right hemisphere lesions can interfere with pragmatic abilities, and particularly with the processing of nonliteral speech acts. Methods: Since the objective of this study was to assess different aspects of pragmatic competence in the right hemisphere damage (RHD) patients, 20 Iranian patients with right hemisphere lesions were examined by adult pragmatic profile (APP) and a novel checklist was introduced for Persian language speaking individuals. Meanwhile, 40 healthy adult individuals, who were age and gender matched with RHD patients, were considered as the control group. After obtaining video records, all subjects were evaluated for 35 pragmatic skills, including 24 verbal, 5 paralinguistic, and 6 nonverbal aspects, by a two-point scale system. Results: Studying RHD patients and their healthy counterparts revealed that the performance by participants with right hemisphere lesions exhibited a high degree of inappropriate pragmatic abilities compared with controls in all domains. Furthermore, RHD patients showed a trend of increasing difficulty in understanding and producing different pragmatic phenomena, including standard communication acts. Conclusion: Present results indicated that the right hemisphere lesions significantly affected pragmatic abilities in verbal, paralinguistic and nonverbal aspects. Such a pattern of performance, which is in line with deficits previously reported for RHD, proved the unquestioned role of the right hemisphere in processing nonliteral language. PMID:25295151

BACKGROUND The objective of this study was to evaluate the association of some factors such as serum levels of homocysteine, folate and B12 vitamin with stroke in acute ischemic stroke patients. METHODS In this case control study, serum levels of homocysteine, folate and B12 vitamin in 93 patients with acute ischemic stroke admitted to Imam Khomeini Hospital between September 2008 and January 2010, and 93 healthy controls were measured. Cerebrovascular risk factors including age, sex, hypertension, hyperlipidemia, smoking, diabetes mellitus, alcohol consumption, coronary artery disease and obesity were recorded. The results were compared between the case and control groups. RESULTS The mean ± standard deviation (SD) of fasting total homocysteine (tHcy) level in acute ischemic stroke patients was 20.58 ± 19.6 µmol/l, which was significantly higher than that of control group being 14.11 ± 9.5 µmol/l (P = 0.002). 39 (41.9%) stroke cases and 25 (26.8%) controls had hyperhomocysteinemia. There were no significant relationships between tHcy, folate and B12 vitamin levels with the above mentioned cerebrovascular risk factors except for smoking (p> 0.05). No significant difference in B12 vitamin and folate levels between patients and healthy controls were detected (P> 0.05). CONCLUSION Hyperhomocysteinemia is common in Iranian patients with acute ischemic stroke and might play a role as an independent risk factor in stroke. PMID:22577454

Background: 22q11.2 microdeletion syndrome is the most common multiple genetic disorder associated with learning disabilities, developmental delays, immune deficiency, hypocalcemia, and cleft palate. Finding some valid criteria for screening of 22q11.2 deletion syndromes in infants would be very helpful in early diagnosis and treatment. Materials and Methods: Since 69% of individuals with 22q11.2 deletion have a palatal abnormality, we studied the prevalence of 22q11.2 deletion syndrome in 378 Iranian patients during a 5-year period, including 291 patients affected with cleft palate only without cleft lip (CPO) and 87 patients affected with velopharyngeal incompetence (VPI) and/or submucous cleft palate (SMCP). DNA copy number was analyzed with multiplex ligation-dependent probe amplification (MLPA) technique. Results: In our study, 15/378 (3.97%) patients with palatal anomalies showed 22q11.2 deletion. Interestingly, this prevalence between syndromic patients was 15/104 (14.42%). Conclusion: It seems that SMCP or VPI, in addition to one or more another features of 22q11.2 deletions, especially developmental delay, may be good criteria for molecular investigation of 22q11.2 region.

MS is an autoimmune disease and interleukin 13 (IL-13) has been proposed to be an important neuroprotective mediator in MS. Because of plausible effect of single nucleotide polymorphisms (SNPs) in expression level or biological activity of any cytokine, we sought to investigate association of IL-13 SNPs, C-1112T, A-1512C and G+2044A, with risk to MS. Sixty-eight RRMS patients and 110 healthy controls were involved in this study. After extraction of genomic DNA, frequency of genotypes and alleles were determined by PCR-RFLP and data were analyzed statistically. Results showed significant higher frequency of CC, CC, and AA genotypes and C, C, and A alleles of -1112CT, -1512AC and +2044GA SNPs respectively, in patients group. There was significant association between -1112C allele with onset age of MS. No significant association was seen between any of genotypes or alleles with expanded disability status scale (EDSS) of patients. Our findings showed significant association between three studied SNPs of IL-13 with susceptibility to MS in Iranian patients. More studies should be done on other IL-13 SNPs, and also polymorphisms of IL-13 receptor and other cytokines to determine the exact role of SNPs in protecting or predisposing of individuals for MS.

Background: Few studies have been conducted on the infertility problems in Iran. This study aimed to investigate the prevalence of infertility problems and related factors in Iranian infertile patients. Materials and Methods: In this cross sectional study, 405 infertile patients referred to Royan Institute, Tehran, Iran, between 2014 and 2015, were selected by simple random sampling. Participants completed the Fertility Problem Inventory (FPI) including 46 questions in five domains (social concern, sexual concern, relationship concern, rejection of parenthood, and need for parenthood). Mean difference between male and female was verified using independent-samples Student’s t test. A generalized linear model (GLM) was also used for testing the effect of variables on the fertility problems. Data was analyzed using Stata software version 13. Results: The mean age (SD) of participants was 31.28 (5.42). Our results showed that 160 infertile men (95.23%) were classified as very high prevalence of infertility problems. Among infertile women, 83 patients (35.02%) were as very high prevalence of infertility problems, and 154 patients (64.98%) were as high prevalence. Age (P<0.001), sex (P<0.001), a history of abortion (P=0.009), failure of previous treatment (P<0.001), and education (P=0.014) had a significant relationship with FPI scores. Conclusion: Bases on the results of current study, an younger male with lower education level, history of abortion and history of previous treatments failure experienced more infertility problems.

Ankylosing spondylitis (AS) is a chronic inflammatory disease, characterized by axial arthritis in which the genetic-environmental factors seem to be involved in the pathogenesis of the disease. This study was performed to investigate the role of polymorphisms of the programmed cell death 1 (PDCD1) gene on susceptibility to AS. In this study, 161 Iranian patients with AS and 208 normal controls were enrolled; two single-nucleotide polymorphisms (SNPs) of the PDCD1 gene PD-1.3 (G, A) in nucleotide position +7146 of intron 4 and PD-1.9 (C, T) in nucleotide +7625 of exon 5 were studied. Analysis of PD-1.3 revealed that 82% of patients and 79% of controls had GG genotype, while GA and AA genotypes were detected in 17% and 0.6% of patients, respectively, and 20% and 1.4% of controls, respectively. Moreover, the genotype CC (PD-1.9) was present in 92% of patients and 97% of controls. Although these differences were not statistically significant between patients and controls, comparisons of genotypes frequencies in the AS patients, based on human leukocyte antigen (HLA)-B27, revealed that all patients who had CT genotype (PD-1.9) were HLA-B27 positive, whereas 30% of patients with CC genotype were HLA-B27 negative. There was no evidence of association for PDCD1 SNPs with AS in our study, but CT genotype (PD-1.9) seems to be associated with HLA-B27 positivity in the patients with AS.

Background: As oral contraceptive pills are available over the counter in pharmacies, pharmacists are professionally responsible for checking and informing patients about every aspect of taking these drugs. Simulated patient method is a new and robust way to evaluate professional performance of pharmacists. Objective: The aim of the present study was to evaluate the pharmacy practice of Iranian pharmacists regarding over-the-counter use of oral contraceptive pills using simulated patient method. Methods: Simulated patients visited pharmacy with a prescription containing ciprofloxacin and asked for oral contraceptive pills. The pharmacist was expected to ask important questions for using these drugs and to inform the patient about them properly. Moreover, the Pharmacists should advise patients in regard to the possible interaction. Results: Ninety four pharmacists participated in this study. In 24 (25.3%) visits, the liable pharmacist was not present at the time of purchase. Furthermore, In 13 (18.57 %) visits by the simulated patients, the liable pharmacists did not pay any attention to the simulated patients even when they asked for consultation. Twenty nine (41.43%) pharmacists did not ask any question during dispensing. Nausea was the most frequent described side effect by pharmacists (27 (38.57%)). Yet important adverse effects of oral contraceptive pills were not mentioned by the pharmacists except for few ones. Only twelve (17.14%) pharmacists mentioned the possible interaction. There was a significant relation between the pharmacists’ gender and detection of possible interaction (p value= 0.048). Conclusion: The quality of the pharmacists’ consultations regarding the over the counter use of oral contraceptive pills was not satisfactory and required improvement. PMID:28042350

Background: Thalassemia is one of the most common monogenic disorders characterized by reduced production of globin chains. Although regular red blood cell (RBC) transfusion support is the main treatment for these patients, it may be associated with complications such as RBC alloimmunization. Aim: The study aimed to determine the incidence of alloimmunization and autoimmunization to RBC antigens in β-thalassemia major patients from Zanjan, Zanjan Province, Iran. Materials and Methods: A total of 49 β-thalassemia major patients comprising 24 females and 25 males (mean age: 18.59 ± 8.16 years; range: 2-40 years) from Northwest Iran were included in a cross-sectional study. Alloantibody screening and identification were done using 3-cell and 10-cell reagent red blood cells, respectively. Autoantibody detection was performed using direct Coomb's test. Results: The incidence of alloimmunization was 16.32% with 10 alloantibodies identified in 8 patients. The most common clinically significant alloantibody identified in alloimmunized patients was anti-Kell (K-antigen) (60%) followed by anti-Rhesus (Rh) (E, c-antigens). The rate of alloimmunization was significantly lower in patients transfused with leukoreduced RBCs compared with those transfused with nonleukoreduced RBCs (9.53% vs 57.14%, P = 0.001). There was no significant correlation between alloantibody formation and the age, gender, hemoglobin levels, number of transfused units, and splenectomy. Conclusion: Transfusion of leukoreduced and phenotypically matched red blood cells for Kell (K) and Rh (E, c) antigens may help reduce the alloimmunization rate in Iranian β-thalassemia major patients. Moreover, autoimmunization to RBC antigens was rare in our patients. PMID:27011679

Objectives: Considering the positive effects of certain nutrients on depression, increasingly prevalent in the contemporary societies, we investigated the nutritional content of prescribed and prohibited foodstuffs for depressed patients in Iranian Traditional Medicine resources. Materials and Methods: In order to conduct the study, credible sources of Iranian Traditional Medicine were primarily reviewed for the prescribed and prohibited foodstuffs for depressed patients. USDA database, as a well-known and valuable source, was then visited to determine the amount of effective nutrients in each foodstuff. Finally, the obtained amounts were compared with each other in three food groups, namely vegetables, fruits and nuts and also high protein products. Results: In Iranian Traditional Medicine texts, the following are prescribed for depression management: basil, coriander, spinach, lettuce, squash, peppermint, dill, chicory, celery, chard, quince, cucumber, watermelon, grape, peach, pomegranate, banana, apple, currant, pistachio, dried fig, almond, egg, chicken, lamb, and trout; cabbage, eggplant, onion, garlic, broad beans, lentils, and beef, meanwhile, are prohibited. In this regard, the effective nutritional content of these foodstuffs was obtained and then compared in the three food groups. Conclusion: This study revealed that spinach, lettuce, chicory, and squash (vegetables), pomegranate and almond (fruits and nuts) and ultimately trout (high protein products) are the best effective foodstuffs on depressed patients from nutritional content aspect.

Objective Chitotriosidase (CT) activity is a useful biomarker for diagnosis and monitoring of Gaucher disease (GD). Its application is limited by some variants in the CT gene. Two main polymorphisms are 24 bp duplication and G102S led to reduce CT activity. The aim of this study was to determine these variants influencing on plasma CT activity. Materials & Methods Blood samples were collected from 33 patients with GD, 15 sibling carriers and 105 healthy individuals serving as controls. CT activity was measured using 4-methylumbelliferyl-β-D-N,N′,N″triacetylchitotrioside substrate in plasma samples. The CT genotypes of 24 bp duplication and G102S variants were determined using PCR and PCR-RFLP. Results Untreated GD patients had a significantly higher CT activity compared to treated patients (P = 0.021). In addition, chitotriosidase activity in carriers was higher rather than controls. Allele frequencies of 24 bp duplication in GD patients, sibling carriers and controls were 0.21, 0.266 and 0.29 and for G102S were 0.318, 0.366 and 0.219, respectively. Different G102S genotypes had not significant effect on CT activity. Chitotriosidase activity has a positive correlation with age in normal group, carriers, and negative correlation with hemoglobin in GD patients. Using cut-off level of 80.75 nmol/ml/h, sensitivity and specificity of CT activity were 93.9% and 100%, respectively. Conclusion Chitotriosidase activity is a suitable biomarker for diagnosis and monitoring of GD. Determination of 24 bp duplication is helpful for more accurate monitoring the GD patient’s therapy. However, it seems that, specifying of the G102S polymorphism is not required for Iranian GD patients. PMID:27843468

Preeclampsia is a pregnancy disease characterized by hypertension and proteinuria. Among several disorders, the imbalance of inflammatory cytokines and the alteration of vitamin D metabolism have been reported in preeclampsia. The effects of calcitriol upon inflammatory cytokines has been demonstrated. In healthy pregnant women there is a shift toward a Th2 cytokine profile, which is necessary for an adequate pregnancy outcome. As compared with normal pregnancy, high pro-inflammatory and low anti-inflammatory cytokine levels have been observed in preeclamptic women. Preeclampsia has been associated with low calcitriol levels and vitamin D deficiency is correlated with a higher risk of the development of this disease. It has been demonstrated that placenta is a source as well as the target of calcitriol and cytokines and placental dysfunction has been associated with preeclampsia. Therefore, the present manuscript includes a review about serum calcitriol levels in non-pregnant, pregnant, and preeclamptic women as well as a review on the fetoplacental vitamin D metabolism in healthy and preeclamptic pregnancies. In addition, circulating and fetoplacental inflammatory cytokines in healthy and preeclamptic pregnancies are reviewed. Finally, the effects of calcitriol upon placental pro-inflammatory cytokines are also explored. In conclusion, maternal and placental calcitriol levels are low in preeclampsia which may explain, at least in part, high pro-inflammatory cytokine levels in this disease.

Abstract Background The TP53 gene is one of the most frequently mutated genes amongst human malignancies, particularly TP53 codon 72 polymorphism. Furthermore, an association between the TP53 codon 72 variants and prostate cancer has been reported in several studies. Although some studies have indicated an association between the TP53 Arg/Arg variant and an increased risk for prostate cancer, other studies have shown a positive correlation between the TP53 Pro/Pro genotype instead. Therefore, to clarify if this polymorphism is associated with an increased risk of prostate cancer in Iranian men, we conducted a case-control study of 40 sporadic prostate cancer patients and 80 benign prostate hyperplasia cases. Methods The TP53 codon 72 was genotyped using an allele specific PCR. Results A significant association between the TP53 codon 72 genotype and prostate cancer risk was found (OR = 6.8, 95% CI = [1.8-25.1], P = 0.005). However, the results of this study did not support an association between age, the Gleason score nor TP53 genotype at codon 72 in prostate cancer patients. Conclusions TP53 codon 72 polymorphism may have a great impact in the development of prostate cancer. PMID:26005655

A single-nucleotide polymorphism (SNP) in the promoter region of MDM2 (SNP309T>G, rs2279744) has been shown to increase the expression of the MDM2 protein in various cancer types. However, only one study has analyzed the role of the MDM2 polymorphism in the development of Kaposi's sarcoma (KS). The association of MDM2 SNP309 with classic KS risk was evaluated in 79 Iranian patients with classic KS and 123 healthy controls. The MDM2 SNP309 was genotyped using PCR and restriction fragment length polymorphism methods. No significant correlation was found between the SNP309 polymorphism in MDM2 promoter and classic KS risk. There was no significant correlation between gender and disease stage. However, a significant association was found between SNP309 GG genotype and younger age (≤50 years) (odds ratio 9.5, 95% confidence intervals 1.5-60, p = 0.03). Our findings support no major role for the MDM2 SNP309 in KS development although it might influence the clinical outcome of KS in younger patients.

AIM: To evaluate the efficacy of pegylated interferon in Iranian chronic hepatitis C patients in relation to interferon-λ (IFNL) polymorphisms. METHODS: This study enrolled patients with chronic hepatitis C referred to the Tehran Blood Transfusion Hepatitis Clinic in 2011. Patients were included in the study if they had no concomitant hepatic illness, were negative for human immunodeficiency virus antibodies, and had no prior history of treatment with any type of pegylated interferon. Patients were treated with 180 μg pegylated interferon alpha-2a (Pegaferon®) weekly and 800-1200 mg ribavirin daily for 24 or 48 wk depending on weight and hepatitis C virus (HCV) genotype. Blood samples were collected from patients to obtain DNA for determination of IFNL rs12979860 and rs8099917 polymorphisms. The virologic response in patients was then evaluated and compared between the different IFNL genotypes. RESULTS: A total of 152 patients with a mean age of 41.9 ± 10.0 years were included in the study, of which 141/152 were men (92.8%). The most frequent HCV genotype was type-1, infecting 93/152 (61.2%) patients. Sustained virologic response (SVR) was achieved in 81.9% of patients with HCV genotype-1 and 91.1% of patients with HCV genotype-3. Treatment success was achieved in 91.2% (52/57) of patients with the IFNL rs12979860 CC genotype and 82.1% (78/95) in those with other genotypes. Similar treatment response rates were also observed in patients with rs8099917 TT (39/45; 86.7%) and non-TT (61/68; 89.7%) genotypes. Univariate analyses identified the following factors which influenced treatment response for inclusion in a multivariate analysis: age, HCV RNA level, stage of liver fibrosis, rs12979860 CC genotype, and aspartate transaminase level. A logistic regression analysis revealed that only the rs12979860 CC genotype was significantly associated with achievement of SVR (OR = 6.2; 95%CI: 1.2-31.9; P = 0.03). CONCLUSION: The rs12979860 CC genotype was associated with

In Haemophilia A (HA), the deficiency in coagulation factor VIII is caused by mutations in the F8 gene. In the past, HA carrier detection in Iran used to be carried out by tracking polymorphic DNA markers - a technical strategy with poor efficacy and accuracy. For some 10 years, however, mutations have been identified by direct DNA sequencing at the Iranian Comprehensive Haemophilia Care Centre (ICHCC), resulting in the detection of 580 different mutations and accurate carrier detection. The aim of this study was to characterize and report the unreported mutations not recorded in the F8 HAMSTeRS database and HGMD, which we have detected amongst all the mutations hitherto identified. After excluding introns 1 and 22 inversions, direct DNA sequencing was used to detect mutations among our patients. These were then confirmed in another affected relative or obligate carrier. Severe cases of HA, where no mutation could be identified, were further investigated by the MLPA method. The new, unreported mutations identified include: 51 missense, 15 nonsense, 45 frame-shifts, 11 splice-site, 1 duplications. We report a large spectrum of mutations identified in the course of the past 10 years at the ICHCC, which offers this service to all patients from regions throughout Iran. Aside from the common introns 1 and 22 inversions, this work demonstrates a high degree of heterogeneity in F8 mutations. The establishment of a comprehensive Iranian HA database will improve the care and genetic counselling of Iranian HA families.

Background: There are many factors that can affect dialysis adequacy; such as the type of vascular access, filter type, device used, and the dose, and rout of erythropoietin stimulation agents (ESA) used. The aim of this study was investigating factors affecting Hemodialysis adequacy in cohort of Iranian patient with end stage renal disease (ESRD). Methods: This is a cross-sectional study conducted on 133 Hemodialysis patients referred to two dialysis units in Sistan-Baluchistan province in the cities of Zabol and Iranshahr, Iran. We have looked at, (the effects of the type of vascular access, the filter type, the device used, and the dose, route of delivery, and the type of ESA used) on Hemodialysis adequacy. Dialysis adequacy was calculated using kt/v formula, two-part information questionnaire including demographic data which also including access type, filter type, device used for hemodialysis (HD), type of Eprex injection, route of administration, blood groups and hemoglobin response to ESA were utilized. The data was analyzed using the SPSS v16 statistical software. Descriptive statistical methods, Mann-Whitney statistical test, and multiple regressions were used when applicable. Results: The range of calculated dialysis adequacy is 0.28 to 2.39 (units of adequacy of dialysis). 76.7% of patients are being dialyzed via AVF and 23.3% of patients used central venous catheters (CVC). There was no statistical significant difference between dialysis adequacy, vascular access type, device used for HD (Fresenius and B. Braun), and the filter used for HD (p> 0.05). However, a significant difference was observed between the adequacy of dialysis and Eprex injection and patients’ time of dialysis (p <0.05). Conclusion: Subcutaneous ESA (Eprex) injection and dialysis shift (being dialyzed in the morning) can have positive impact on dialysis adequacy. Patients should be educated on the facts that the type of device used for HD and the vascular access used has no

Depression is a frequent symptom in multiple sclerosis (MS) which has a negative impact on quality of life and cognitive status. The purpose of this study was to determine the prevalence and associated factors of depression, and status of antidepressant use in Iranian MS patients. One-hundred and sixty patients with definite MS were included. Demographic and clinical characteristics were recorded. Fatigue and depression were evaluated using the fatigue severity scale and Beck depression inventory-II. Cognitive performance and disability were examined by mini-mental status examination and expanded disability status scale. Multiple logistic regressions were used to determine the associated factors of depression and antidepressant use. The prevalence of depression and severe depression was 59.4 and 18.1 %, respectively. However, only 21.1 % of patients were on antidepressant treatment, while the prevalence of unrecognized/untreated depression was found to be as high as 44.1 %. Multivariable analysis showed that fatigue (P < 0.0001, OR = 5.98, 95 % CI = 2.9-12.3) and older age (P = 0.027, OR = 2.24, 95 % CI = 1.09-4.6) were associated with depression in MS patient. A significant association was found between fatigue and antidepressant use (P = 0.001, OR = 6.81, 95 % CI = 2.26-20.48). Our findings demonstrate that depression is significantly associated with fatigue and older age, regardless of other factors. Moreover, despite the high prevalence of depression in MS, most patients do not receive adequate treatment.

Aim: The aim of this study was to evaluate the likelihood ratio and frequency of DQ2 and DQ8 in Iranian patients with celiac disease (CD). Background: The HLA DQ2 and HLA DQ8 are the important mediators in the development of celiac disease. A few studies evaluated the frequency of HLA DQ2 and HLA DQ8 haplotypes among the Iranian population with low sample size. Patients and methods: In this cross-sectional study, to predict HLA–DQ2 and DQ8 haplotypes, 141(73 male, 78 female) confirmed CD patients compared to 151 healthy controls were enrolled into this study during 2013-2014. HLA DQ2/ DQ8 haplotypes was determined in cases and controls using PCR-SSP technique. Results: DQ2 and DQ8 were positive in 80% (n=111) and 49% (n= 69) of CD patients and 36% (n=61) and 13% (n=21) of control group respectively. Moreover, 32% (n=45) of CD patients and 5.3% (n=8) of the control group were carrier of both haplotypes. In the case group about one-third of patients (32.2%) were positive for carrying both DQ2 and DQ8 heterodimers while only 5.3% (n=8) of the control group were carrier. In addition, the positive likelihood ratio of DQ2 and DQ8 were 1.74 (CI: 1.4- 2.1), and 2.6 (CI: 1.8– 2.7), respectively. Conclusion: The result of this study showed that the frequency of DQ8 among our population is higher than those reported by European countries, but it is close to those founded in South America and Middle East. This result suggests that the higher prevalence of HLA DQ8 pattern in Iranian CD patients is similar to non-European patients. PMID:26744610

Background Candida albicans (C. albicans) has several virulence factors, in particular heat shock protein 90 (Hsp90), which is expressed by Hsp90 gene. The purposes of this study were to assess the expression of Hsp90 gene in clinical and control isolates of C. albicans obtained from different geographical regions (Malaysia and Iran), different temperatures (25°C, 37°C and 42°C) and mice with candidiasis. Methods C. albicans isolates were cultured onto sabouraud dextrose agar (SDA). The assessment of the expression of Hsp90 gene was performed using real time-polymerase chain reaction (RT-PCR). Results The results showed a significant increase in the expression of C. albicans Hsp90 gene under high thermal shock (42°C) when compared to other temperatures tested (P-value = 0.001). The mean differences in the expression of Hsp90 gene at 37°C were 0.20 (95% confidence interval (CI) 0.13–0.29) between Malaysian and Iranian controls (P-value = 0.040) and 0.47 (95% CI 0.27–0.60) between Malaysian and Iranian patients (P-value = 0.040). Conclusion The results demonstrated that the expression of C. albicans Hsp90 gene varied between Malaysian and Iranian subjects, representing the efficacy of geographical and thermal conditions on virulence gene expression.

There are a limited number of reports indicating the role of human leukocyte antigen (HLA) class I alleles in pemphigus vulgaris. This study was designed to highlight the association of HLA class I alleles with pemphigus vulgaris in Iran. Fifty patients with pemphigus vulgaris, diagnosed based on clinical, histological and direct immunofluorescence findings were enrolled into this study. The control group consisted of 50 healthy, age- and sex-matched individuals. HLA typing of class I (A, B and C alleles) was carried out using polymerase chain reaction based on the sequence-specific primer method. This study showed the higher frequency of HLA-B*44:02 (P = 0.007), -C*04:01 (P < 0.001), -C*15:02 (P < 0.001) and -C*16:01 (P = 0.027) in the patient group, compared to the controls, while the frequency of HLA-C*06:02 (P < 0.001) and -C*18:01 (P = 0.008) in the patients with pemphigus vulgaris was significantly lower than the controls. Regarding the linkage disequilibrium between HLA class I alleles, the HLA-A*03:01, -B*51:01, -C*16:02 haplotype (4% vs 0%, P = 0.04) is suggested to be a predisposing factor, whereas HLA-A*26:01, -B*38, -C*12:03 haplotype (0% vs 6%, P = 0.01) is suggested to be a protective factor. In conclusion, it is suggested that HLA-B*44:02, -C*04:01, -C*15:02 alleles and HLA-A*03:01, -B*51:01, -C*16:02 haplotype are susceptibility factors for development of pemphigus vulgaris in the Iranian population, while HLA-C*06:02, -C*18:01 alleles and HLA-A*26:01, -B*38, -C*12:03 haplotype may be considered as protective alleles.

Abstract Background Awareness of hyperdontia pattern/prevalence can be useful in early diagnosis and prevention by general practitioners, pediatric dentists, and orthodontists. Since the previous results regarding the pattern of hyperdontia (supernumerary teeth) are controversial, this study aimed to assess this subject among Iranian orthodontic patients. Methods All approved panoramic radiographs of 3374 orthodontic patients (aged 10 to 20 years old) who had visited orthodontic departments of all Tehran dentistry universities and 10 private clinics during the years 1999-2009 were investigated to establish the prevalence/pattern of hyperdontia in permanent dentition (excluding third molars). The data were analyzed using a chi-square, a chi-square goodness-of-fit, and a Fisher exact test (α=0.05). Results Of the patients, 2012 were female and 1362 were male. The prevalence of hyperdontia was 0.72% (14 females [0.69% of females], 10 males [0.73% of males], female-to-male ratio=1:1.055). The difference between the genders was not significant (P = 0.896). No double or multiple supernumeraries were found. The most common accessory teeth were mesiodens (58.3%), maxillary laterals (25%), and maxillary premolars (16.7%). Hyperdontia was significantly more common (P=0.000) in maxilla (there was only one mandibular accessory tooth). It was more frequent in the anterior segment (P=0.000). However the occurrence was not significantly different between bimaxillary right and left quadrants (P=0.6). Conclusion Hyperdontia was more common in premaxilla, and the most common accessory tooth was mesiodens. Unlike earlier studies, no bilateral accessory teeth were found. Also no gender dimorphism was discerned. PMID:26171338

Background Hepatitis C is prevalent among thalassemia patients in Iran. It is mainly transfusion mediated, in particular among patients treated before 1996 when blood screening was introduced. Objectives The current study aimed to investigate why patients still seroconvert to anti-HCV in Iranian thalassemia centers. Patients and Methods During 2006-2007 sera were sampled from 217 anti-HCV positive thalassemia patients at nine thalassemia centers in Tehran and Amol city, where 34 (16%) patients had been infected after 1996. The HCV subtype could be determined by sequencing and phylogenetic analysis of partial NS5B and/or 5׳NCR-core region in 130 strains. Results 1a (53%) was predominant followed by 3a (30%), 1b (15%), and one strain each of 2k, 3k and 4a. Phylogenetic analysis revealed 19 clades with up to five strains diverging with less than six nucleotides from each other within subtypes 1a and 3a. Strains in seven clades were from nine patients infected between 1999 and 2005 and similar to strains from eight patients infected before 1996, indicating ongoing transmission at the centers. Further epidemiological investigation revealed that 28 patients infected with strains within the same clade had frequently been transfused at the same shift sitting on the same bed. An additional eight patients with related strains had frequently been transfused simultaneously in the same room. Conclusions The results suggest nosocomial transmission at these thalassemia centers both before and after the introduction of blood screening. Further training of staff and strict adherence to preventive measures are thus essential to reduce the incidence of new HCV infections. PMID:23585766

Background. Epicardial fat tissue, another form of visceral adiposity, has been proposed as a new cardiometabolic risk factor, and the possible association of epicardial fat with hypertension has been shown in some recent studies. Although epicardial fat thickness (EFT) is associated with hypertension, the relationship between preeclampsia and EFT is still unknown. The purpose of this paper is to investigate the association between the echocardiographic EFT and the severity of preeclampsia in pregnant women. Methods. Forty women with preeclampsia were recruited and thirty-five normal pregnant women were matched for both maternal age and gestastional age served as control. The materials were collected immediately after delivery of the fetus, before placenta expulsion and before clamping of the umblical cord in patients and controls whom were in fasting state. Total cholesterol, high-density lipoprotein cholesterol (HDL), and triglyceride levels (TG) and low-density-lipoprotein cholesterol (LDL), and homeostatic model assessment of insulin resistance (HOMA-IR) levels were assessed. EFT was measured by using transthoracic echocardiography. Results. Among the preeclamptic women, 12 were diagnosed with severe preeclampsia and 28 mild preeclampsia. There were no statistically significant differences between patients with preeclampsia and normal pregnancy except when they are divided according to systolic and diastolic blood pressure, proteinuria levels, and parity and EFT levels. Among women with preeclampsia (n = 40), 30% had severe disease. Women with mild and severe preeclampsia had significiantly higher blood pressures at delivery and earlier gestational ages in comparison to control subjects. Although TG, VLDL and LDL, HDL, and HOMA-IR levels (P > 0.05) were comparable between preeclampsia and normal pregnancies, EFT levels were significiantly higher in patients with preeclampsia. Moreover, in subgroup analysis, patients with severe preeclampsia had higher EFT

Regulatory T cells (Tregs; CD4+CD25highFoxp3+) are critical in maintaining immune tolerance during pregnancy and uterine vascularization. In this study, we show that, in Mexican women with different preeclamptic severity levels, the number of Tregs and the subset of CD4+CD25highFoxp3+ are decreased compared with those of normotensive pregnant women (NP). Moreover, a systemic inflammatory state is a pivotal feature in the pathogenesis of this disorder and could be related to hypertension and endothelial dysfunction. Likewise, we observed elevated levels of IL-6, TNF-α, and IL-8 in the serum of severe preeclamptic patients (SPE); no differences were found in the IL-1β and IL-10 levels compared with those of NP patients. An analysis of chemokines in the preeclamptic serum samples showed high levels of CXCL10, CCL2, and CXCL9. Our findings suggest that the preeclamptic state is linked with systemic inflammation and reduced numbers of Tregs. PMID:25574467

Objective: Multiple sclerosis (MS) is a chronic autoimmune disease due to demyelination of the central nervous system. It is believed that cytokines are involved in the pathogenesis of MS. The interleukin-2 (IL2) gene is powerful functional candidate that is involved in immune regulation and operation. In this study, for the first time, we investigated the effect of -475 A/T and -631 G/A IL2 polymorphisms on MS disease in Iranian patients. Materials and Methods: In this case-control study, 100 MS patients (mean age: 32.95 ± 6.51 years, age range: 20-42 years) selected according to McDonald criteria, and 100 ethnically, sex and age matched healthy controls (mean age: 29 ± 7.8 years, age range: 20-52 years) with no personal or family history of autoimmune diseases were studied. The restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) method was applied to define different alleles and genotypes of IL2 promoter single nucleotide polymorphism -475 A/T as well as -631 G/A among individuals. χ2 was calculated and Fisher’s exact test was applied to analyze the obtained data. The value of p < 0.05 was considered significantly . Results: Evaluation of the -475 IL2 revealed that T allele and A/T genotype are present in 2% and 4% of MS patients, respectively, whereas T allele was absent in control samples. The comparison between alleles and genotypes in MS patients and healthy controls was not significant (p=0.1). For the -631 position, 1% and 2% of MS patients carried A allele and A/G heterozygote genotypes, respectively. All control samples had G allele and G/G genotype. The differences between patients and controls were not significant (p=0.4). Moreover, our results showed a very low frequency of T at -475 and A at -631 IL2 position in each of the two groups. Conclusion: Both -475 and -631 IL2 polymorphisms were higher in MS patients as compared to controls, but the frequency differences were not significant. Based on these data, it is

The protective immune response against Brucella involves T-cell-mediated immunity. T-lymphocyte receptors, CD28 and cytotoxic T-lymphocyte-associated protein-4 (CTLA-4), bind the same ligands, CD80 (B7-1) and CD86 (B7-2) on antigen-presenting cells and regulate T cell activation. CD28 delivers stimulatory signals whereas CTLA-4 provides inhibitory signals for T cell activation. Here, we investigated the association of four polymorphisms in CTLA4 (+49A/G [rs231775] and -318 C/T [rs5742909]) and its ligand CD86 (+1057 G/A [rs1129055] and +2379G/C [rs17281995]) with brucellosis infection. The study included 153 Iranian patients with active brucellosis and 128 healthy individuals as the control group. Genotyping of the CTLA4 and CD86 variants was performed using tetra amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) and PCR-restriction fragment length polymorphism analysis, respectively. It was found that the CTLA4 -318 CT genotype and T allele were present more frequently in cases than in controls and are therefore associated with an increased risk for brucellosis (-318 TT genotype; OR = 2.544, P = 0.002). Likewise, the CD86 +1057 GA and AA genotypes and A allele were associated with an increased risk of brucellosis (+1057 AA genotype; OR = 3.81, P = 0.001). However, no statistically significant difference between brucellosis patients and controls in the allele and genotype distributions of CTLA4, +49A/G (P = 0.859) and CD86, +2379G/C (P = 0.476) was found. In conclusion, CTLA4 -318 CT genotype and T allele and the CD86 +057 GA and AA genotypes and A allele play roles as risk factors for developing brucellosis infection in Iran.

Periodic fever syndromes are a group of diseases characterized by episodes of fever with healthy intervals between febrile episodes. The first manifestation of these disorders are present in childhood and adolescence, but infrequently it may be presented in young and middle ages. Genetic base has been known for all types of periodic fever syndromes except periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA). Common periodic fever disorders are Familial Mediterranean fever (FMF) and PFAPA. In each patient with periodic fever, acquired infection with chronic and periodic nature should be ruled out. It depends on epidemiology of infectious diseases. Some of them such as Familial Mediterranean fever and PFAPA are common in Iran. In Iran and other Middle East countries, brucellosis, malaria and infectious mononucleosis should be considered in differential diagnosis of periodic fever disorders especially with fever and arthritis manifestation. In children, urinary tract infection may be presented as periodic disorder, urine analysis and culture is necessary in each child with periodic symptoms. Some malignancies such as leukemia and tumoral lesions should be excluded in patients with periodic syndrome and weight loss in any age. After excluding infection, malignancy and cyclic neutropenia, FMF and PFAPA are the most common periodic fever disorders. Similar to other countries, Hyper IgD, Chronic Infantile Neurologic Cutaneous and Articular, TRAPS and other auto-inflammatory syndromes are rare causes of periodic fever in Iranian system registry. In part 1 of this paper we reviewed the prevalence of FMF and PFAPA in Iran. In part 2, some uncommon auto-inflammatory disorders such as TRAPS, Hyper IgD sydrome and cryopyrin associated periodic syndromes will be reviewed. PMID:25793039

Objectives: Considering the increasing prevalence of depression in modern societies and the positive effects of omega-3 polyunsaturated fatty acids on depression, this study aims to investigate the omega-3 and omega-6 content of various foodstuffs, prescribed or prohibited by Iranian Traditional Medicine (ITM). Materials and Methods: Firstly, reliable sources of Iranian Traditional Medicine were reviewed in order to identify the prescribed and prohibited foodstuffs for depressed patients. Afterwards, according to the online database of United States Department of Agriculture (URL: http://ndb.nal.usda.gov/ndb/search/list), the ratio of linoleic acid to alpha linolenic acid (as representatives of omega-6 and omega-3, respectively) was identified in each foodstuff. Finally, the ratios of omega-6 to omega-3 were compared between seven food groups of vegetables, fruits, dry goods, high protein products, dairies, breads, and spices. Results: Based on the resources of Iranian Traditional Medicine, the following foods are prescribed for depressed patients: basil, coriander, spinach, lettuce, squash, peppermint, dill, chicory, celery, beet, quince, cucumber, watermelon, grape, peach, pomegranate, banana, apple, currant, pistachio, dried fig, almond, egg, chicken, lamb, trout, milk, bread without bran, saffron, oregano, and coriander seeds. On the other hand, cabbage, eggplant, onion, garlic, broad beans, lentils, beef, whole wheat bread, and mustard are prohibited. It should be noted that omega-3 content in some prescribed foods is more than that of the prohibited ones. Conclusion: The present study showed that mint, basil, spinach, lettuce, squash, lamb, saffron, oregano, cucumber, pistachio, milk, and also wild trout can be considered as medicinal foods for depressed patients.

Human papillomavirus (HPV), a major pathogen of human cervical cancer, contains a full-length L1 gene encoding its surface capsid protein. One group of potential vaccine candidates against this virus in Iranian patients is based on surface protein components such as HPV31 L1 protein that can make virus-like particles (VLPs). The high immunity response stimulation of this effecter VLP was observed in host, suggesting that the individual characteristics of a particular effecter may require empirical testing for vaccination. In the present study, we decided to clone and express HPV31 L1 protein to investigate its use as a subunit vaccine and furthermore to insert the gene into an Escherichia coli background so as to analyze production of this recombinant protein. We report the presentation of HPV31 in 100 cervical lesion tissue samples based on polymerase chain reaction (PCR). Type of lesion, age, and other characteristics were reviewed and confirmed by a pathologist. The sequence from L1 genes of HPV was selected using special primers. The gene encoding the major capsid protein L1 was used for subcloning in pTG19-T and pET-32a plasmid. The recombinant protein expression was confirmed by RT-PCR using L1 primers and detected by absorption sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblot testing. The results presented here offer new insights into the in vivo response of HPV31 in Iranian patients and European models. On the other hand, the use of recombinant L1 protein for Iranian patient protection as well as vaccination studies will permit testing of this antigen protection rate and open the way to the discovery of protein biomarkers for monitoring clinical and subclinical cervical cancers.

Objective:To compared serum CRP levels and biochemical relation in PCOS patients with normal Iranian women. Materials and methods:This case-control study was performed on 52 individuals with PCOS (Rotterdam 2003 criteria). The cases were compared to 104 healthy non-PCOS, 20 to 35-year-old female subjects with no history of diabetes or renal diseases. Blood samples were taken on the 2nd to the 5th day of menstrual cycle for the evaluation of CRP levels, triglyceride, insulin, androstronedion, testestrone and total cholesterol. Results:The mean CRP was 1.38 (± 0.43) mg /dl in the PCOS group, and 1.08 (± 0.49) mg /dl (p= 0.240) in control group.High-Sensitivity C-Reactive Protein (HS-CRP) was positively correlated with the Body Mass Index (BMI) (r = 0.36, p= 0. 001). Before adjusting for age and BMI, CRP was correlated with LDL (r= 0.16, p= 0.03), total cholesterol (TC) (r= 0.17, p= 0. 03), Triglycerid (TG) (r= 0.23, p= 0.003), and the insulin (r= 0.20, p= 0. 01) notably in PCOS group. However, after adjustment was made for age and BMI, the correlation was attenuated in PCOS. The regression analyses depicted that CRP level was not under the influence of other medical parameters Conclusion:The results showed that mean CRP level was not significantly different between PCOs and normal women. After adjustment for age and BMI, CRP was not associated with any biochemical marker evaluated in this study. It seems that studied biochemical serum levels were mostly associated with obesity. So reduction of BMI may normalize the serum levels of CRP and other biochemical parameters. PMID:25904961

Chemokines and their receptors are crucially important in the pathogenesis of acute myeloblastic leukemia (AML). The CC chemokine receptor 5 (CCR5) is a specific chemokine receptor for CC chemokine ligand 3 (CCL3), CCL4 and CCL5 which all play key roles in identifying cancer properties and localization of leukemia cells. It has been demonstrated that the known mutation in CCR5 gene (CCR5-Δ32) leads to mal-expression of the receptor and affect its function. The aim of this study was to determine the rate of CCR5-Δ32 mutation within Iranian AML patients. In this study, blood samples were obtained from 60 AML patients and 300 healthy controls. The CCR5-Δ32 mutation was evaluated using Gap-PCR technique. Our results showed that CCR5-Δ32 mutation was not found in the patients, while three out of the controls had hetrozygotic form of this mutation. The rest of studied samples had the wild form of the gene. According to these findings, it can probably be concluded that the CCR5-Δ32 is not associated with susceptibility to AML in Iranian patients.

Interferon-gamma (IFN-γ) and P2X7 receptor are crucial for host defence against mycobacterial infections. Recent studies have indicated that IFN-γ, IFN-γ receptor 1 (IFN-γR1) andP2X7 gene polymorphisms are associated with susceptibility to pulmonary tuberculosis (TB). However, the relationship between IFN-γ and P2X7 polymorphism and TB susceptibility remains inconclusive in Iranian population. For this reason, single nucleotide polymorphisms (SNPs) in IFN-γ (G+2109A), IFN-γR1 (G-611A) and P2X7 genes (at -762, 1513 position) in patients (n = 100) were assessed using PCR-RFLP. Data were analysed with SPSS version 18. For the 2109 loci of IFN-γ gene, the frequency of mutant alleles between patients and controls were not statistically significant. However, there was a significant difference between the TB patient and controls for -611 alleles of IFN-γR1 (P = 0.01). Additionally, the frequency of P2X7 gene polymorphisms (SNP-762 and 1513) between patients and controls was statistically significant. In conclusions, our study revealed a significant association of IFN-γR1 and P2X7 genes polymorphisms with risk of developing TB in Iranian population.

Objective: Tenofovir is among the first-line treatments for chronic hepatitis B (CHB) virus infection. We evaluated the efficacy and safety of Tenofovir in treatment of Iranian patients with CHB. Methods: Forty treatment-native patients with CHB but without concurrent hepatitis C or human immunodeficiency virus infections were treated with Tenobiovir(™) 300 mg/day. The hepatitis B virus (HBV) DNA load, hepatitis B e antigen (HBe Ag), anti-hepatitis B e antibody (HBe Ab), liver enzymes, and creatinine were measured before and at least 3 months after the treatment. Findings: The mean age of patients was 38.1 ± 12.4 years and 65% of them were male. Seventeen (42.5%) patients were HBe Ag-positive and 15 (37.5%) patients had alanine aminotransferase (ALT) of two times above the normal. The HBV DNA load was significantly decreased after the treatment (P < 0.001). Twenty-seven (67.5%) patients had viral load of ≤2000 IU/ml and 22 (55%) patients had undetectable HBV DNA level after the treatment. Among positive HBe Ag patients, the HBe Ag became negative in 15 (88.2%) patients after the treatment and HBe Ab became positive in 3 (17.6%) patients. Liver enzymes’ levels were significantly decreased after the treatment (P <0.05) and ALT transaminase level became normalized in 86.7% (13 out of 15) of cases with baseline levels twice the normal. Conclusion: Treatment response rate to Tenofovir in Iranian patients with CHB was high. The virological and serological response rate and safety of Tenofovir in our population was comparable to other populations. Considering availability and costs, Tenobiovir(™) could be recommended as the first-line therapy of chronic HBV infection in Iran. PMID:27512706

Background Increased prevalence of depression among patients with Rheumatoid arthritis (RA) has been described previously. However, the impact of depression among Iranian patients has not yet been investigated. Objectives Here, the prevalence of depression was assessed and the effect of disease-related characteristics including pain, weakness and rheumatoid factor (RF) status on incidence of depression was evaluated. Materials and Methods Patients with RA, who were referred to rheumatology clinics of Kermanshah University of Medical Sciences and healthy subjects from the general population of Kermanshah participated in this investigation. Depression was assessed using Beck’s depression inventory II (BDI II). Pain and weakness were assessed subjectively by patients’ self-report. Data was collected during a year between 2012 and 2013. Chi-square test and independent t-test were used. Results One hundred and seventy-one patients with RA and 198 healthy individuals participated in this investigation. In the RA group, depressive mood was detected in 45.7% of patients, which was significantly higher than healthy subjects (P = 0.008). Depression was more common in elderly patients (> 50 years old) in comparison with healthy subjects at a similar age (P = 0.03). Pain and weakness had no influence on depression incidence (P = 0.14 and 0.19, respectively) whereas patients with negative RF status were significantly more susceptible to severe depression (P: 0.001). Conclusions Depression is more common among Iranian patients with RA (45%) than healthy subjects regardless of gender. Depression has a significant association with older age. Negative RF status may predict future risk of depression. PMID:27822280
Background Patient preference is one of the main components of clinical decision making, therefore leading to the development of patient decision aids. The goal of this study was to describe physicians’ and patients’ viewpoints on the barriers and limitations of using patient decision aids in Iran, their proposed solutions, and, the benefits of using these tools. Methods This qualitative study was conducted in 2011 in Iran by holding in-depth interviews with 14 physicians and 8 arthritis patient. Interviewees were selected through purposeful and maximum variation sampling. As an example, a patient decision aid on the treatment of knee arthritis was developed upon literature reviews and gathering expert opinion, and was presented at the time of interview. Thematic analysis was conducted to analyze the data by using the OpenCode software. Results The results were summarized into three categories and ten codes. The extracted categories were the perceived benefits of using the tools, as well as the patient-related and physician-related barriers in using decision aids. The following barriers in using patient decision aids were identified in this study: lack of patients and physicians’ trainings in shared decision making, lack of specialist per capita, low treatment tariffs and lack of an exact evaluation system for patient participation in decision making. Conclusions No doubt these barriers demand the health authorities’ special attention. Hence, despite patients and physicians’ inclination toward using patient decision aids, these problems have hindered the practical usage of these tools in Iran - as a developing country.

We have previously suggested that in a Japanese population the susceptible locus for Behçet's disease (BD) is HLA-B51 itself. To confirm this finding in another population, we performed HLA class I typing using the PCR-SSP method and analyzed eight polymorphic markers distributed within 1100 kb around the HLA-B gene using automated sequencer and subsequent automated fragment detection by fluorescent-based technology with the DNA samples of 84 Iranian patients with BD and 87 healthy ethnically matched controls. As a result, three microsatellite alleles (MICA-A6, MIB-348, C1-4-1-217) and HLA-B51 were found to be strongly associated with BD. Of these alleles HLA-B51 is the most strongly associated allele. There were no alleles that were increased in allele frequency at any microsatellite loci centromeric of MICA or telomeric of HLA-B51. Therefore, HLA-B51 was confirmed to be by far the most strongly associated gene with BD in an Iranian population.

Preeclampsia is a pregnancy disease affecting 5 to 8% of pregnant women and a leading cause of both maternal and fetal mortality and morbidity. Because of a default in the process of implantation, the placenta of preeclamptic women undergoes insufficient vascularization. This results in placental ischemia, inflammation and subsequent release of placental debris and vasoactive factors in the maternal circulation causing a systemic endothelial activation. Several microarray studies have analyzed the transcriptome of the preeclamptic placentas to identify genes which could be involved in placental dysfunction. In this study, we compared the data from publicly available microarray analyses to obtain a consensus list of modified genes. This allowed to identify consistently modified genes in the preeclamptic placenta. Of these, 67 were up-regulated and 31 down-regulated. Assuming that changes in the transcription level of co-expressed genes may result from the coordinated action of a limited number of transcription factors, we looked for over-represented putative transcription factor binding sites in the promoters of these genes. Indeed, we found that the promoters of up-regulated genes are enriched in putative binding sites for NFkB, CREB, ANRT, REEB1, SP1, and AP-2. In the promoters of down-regulated genes, the most prevalent putative binding sites are those of MZF-1, NFYA, E2F1 and MEF2A. These transcriptions factors are known to regulate specific biological pathways such as cell responses to inflammation, hypoxia, DNA damage and proliferation. We discuss here the molecular mechanisms of action of these transcription factors and how they can be related to the placental dysfunction in the context of preeclampsia. PMID:23785430

Background: Matrix metalloproteinase 9 (MMP9) -1562C>T (rs3918242) polymorphism has been proposed as a risk factor for coronary artery disease (CAD) with conflicting results. The aim of the present study was to investigate the association of -1562C>T genetic polymorphism, gene expression and circulating levels of MMP9 with CAD risk in an Iranian subpopulation in in Zanjan City. Materials and Methods: This was a retrospective case–control study we investigated retrospectively 100 patients with angiographically verified CAD and 100 matched controls. Genotyping of -1562C>T polymorphism was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Gene expression levels and circulating levels of MMP9 was determined by real-time reverse transcription-PCR and enzyme immunoassay method, respectively. Statistical analysis was done using Student's t-test or Chi-square test by SPSS 16 software. Results: The mean circulating levels of MMP9 were significantly higher in CAD Group than control group (P = 0.002). Mean plasma levels of MMP9 were also significantly higher in triple vessel stenosis patients than double vessel or single vessel stenosis patients (P < 0.001). Moreover, mean plasma levels and gene expression levels of MMP9 were significantly higher in T allele carrier than C allele carrier of MMP9 -1562C>T polymorphism (P = 0.002, P = 0.01, respectively). However, genotype and allele frequencies of MMP9 -1562C>T polymorphism were similar between CAD patients and controls (P > 0.05). Additionally, the -1562C>T polymorphism of MMP9 gene didn't increase the risk of CAD in dominant (P = 0.537) or recessive (P = 0.249) genetic models. Conclusion: Our study demonstrated that circulating levels of MMP9 but not -1562C>T polymorphism of MMP9 gene may be a risk factor for development and severity of CAD in an Iranian subpopulation in Zanjan.

In order to define the protein expressional changes related to the process of meglumine antimoniate resistance in anthroponotic cutaneous leishmaniasis (CL), we performed a comparative proteomics analysis on sensitive and resistant strains of Leishmania tropica isolated from Iranian CL patients. Cell proteins were analysed with 2-dimensional electrophoresis and differentially expressed proteins were identified by matrix-assisted laser desorption/ ionization time-of-flight mass spectrometry. Image analysis of the matched maps identified 7 proteins that were either over- or down-expressed: activated protein kinase c receptor(LACK), alpha tubulin (x2), prostaglandin f2-alpha synthase, protein disulfide isomerase, vesicular transport protein and a hypothetical protein. The study shows the usefulness of proteomics in identifying proteins that may express differences between sensitive and resistant L. tropica isolates.

Introduction Preeclampsia is a pregnancy-specific complication that significantly contributes to maternal and perinatal morbidity and mortality worldwide, even more so in developing countries such as Nepal. The potential contribution of dyslipidemia and elevated levels of oxidized low-density lipoprotein (oxLDL) in the pathogenesis of preeclamptic pregnancies has been observed in several studies. The aim of this study was to compare the maternal lipid profile parameters and particularly oxLDL between preeclamptic and healthy pregnancies and also correlate oxLDL with other lipid profile parameters. Patients and methods A total of 54 preeclamptic women were selected as cases for this cross-sectional study. Age and gestational week-matched 60 pregnant women were enrolled as controls. Preeclampsia was defined as per Australasian Society Consensus Statement research definition. The serum lipid parameters were measured using automated enzymatic systems and a competitive enzyme-linked immunosorbent assay was used to determine oxLDL concentrations in the serum. Student’s t-test was used to compare oxLDL levels between preeclamptic and healthy pregnancies, and Pearson’s correlation analysis was carried out to assess the relation between oxLDL and other variables. Results The mean values of serum total cholesterol, triglyceride, non-high-density lipoprotein-cholesterol (non-HDL-c) and oxLDL were significantly higher in the preeclamptic cases (P<0.01). However, the levels of low-density lipoprotein cholesterol (LDL-c and HDL-c) did not significantly differ between the two groups. oxLDL had a significant positive correlation (P<0.01) with total cholesterol, triglyceride, LDL-c and non-HDL-c, and a negative correlation with HDL-c. Conclusion The atherogenic type of dyslipidemia and high oxLDL levels are associated with preeclamptic pregnancies. The lipid parameters, however, seem to be poor markers of the severity of preeclampsia. Further prospective studies are needed to

Preeclampsia is a common disease that can occur during human pregnancy and is a leading cause of both maternal and neonatal morbidity and mortality. Inadequate trophoblast invasion and deficient remodeling of uterine spiral arteries are associated with preeclampsia (PE). The development of this syndrome is thought to be related to multiple factors. Recently, we isolated patient-specific human amniotic epithelial cells (AECs) from the placentas of 3 women with normal pregnancy and 3 with preeclamptic pregnancy. Since the characteristics of human AECs in PE are different from those in normal pregnancy, we sought to confirm the genes differentially expressed between preeclamptic pregnancy and normal pregnancy. Therefore, we performed transcriptome analysis to investigate the candidate genes associated with the possible pathophysiology of preeclampsia. Pathway analysis was performed using the Database for Annotation, Visualization, and Integrated Discovery (DAVID) and Kyoto Encyclopedia of Genes and Genomes (KEGG) online resource. In this study, we selected a total of 12 pathways and focused on extracellular matrix-related and biological adhesion molecules. Using RT-PCR array and real-time PCR, we confirmed that COL16A1, ITGB2, and LAMA3 were significantly up-regulated, but ITGA1, ITGA3, ITGA6, MMP1, MMP3, MMP10 and MMP11 were significantly down-regulated in preeclamptic fetal origin cells. Taken together, we suggest that the genes and pathways identified here may be responsible for the occurrence and development of PE, and controlling their expression may play a role in communication with fetal-maternal placenta to keep normal pregnancy.

Objective(s): Epidermolysis bullosa is one of the most important series of mechano-bullous heritable skin disorders which is categorized into four major types according to the layer that bullae forms within basement membrane zone. In dystrophic form of the disease, blisters are made in the sublamina densa zone, at the level of type VII collagen protein which produce anchoring fibrils. Type VII collagen gene is the only responsible gene for this form. The aim of this study was to survey causative mutations of type VII collagen gene among Iranian patients with epidermolysis bullosa. Materials and Methods: For this purpose, exons 73-75 were investigated by polymerase chain reaction followed by direct sequencing. Results: In current study, we found three different point mutations in type VII collagen alleles in 7 out of 50 patients. Four patients were homozygous for a new deletion which resulted in frame shift (p.Pro2089fs). Two patients were homozygous for a recurrent glycine substitution (p.G2031S) and one patient was detected with an allele carrying a substitution (p.R2069C). Conclusion: The results emphasized heterogeneity in the type VII collagen gene and will provide a sign for early diagnosis and future study of the disease pathogenesis. PMID:27746867

Multiple sclerosis (MS) is a chronic neuroinflammatory demyelinating disease of the central nervous system. The cytokine genes are involved in autoimmune diseases such as MS. In this study, we report the influence of −330 interleukin-2 (IL2) gene polymorphism on its plasma levels in a group of Iranian MS patients. In this study 100 MS patients and 100 ethnically, age, and sex matched healthy controls were selected from Medical Genetics Department of Sarem Women Hospital. Blood samples of all individuals were collected in EDTA tubes. The restriction fragment length polymorphism PCR (RFLP) method was applied to determine various alleles and genotypes in these individuals. Plasma concentration of IL2 was measured in all the samples using human IL2 kit. The frequency of −330 T/T IL2 genotype was higher in MS patients compared to normal individuals. Accordingly, the plasma levels of IL2 were significantly higher (P < 0.0001) in patients when compared to the control group. In conclusion, in case of MS patients the −330 T/T IL2 genotype is associated with higher plasma levels of IL2. PMID:24959373

It is well known that Behçet's disease (BD) is strongly associated with human leukocyte antigen (HLA) B51 in many ethnic groups. However, there has been no published report as yet with respect to this association among the Iranian people. Furthermore, since it is now known that the B51 antigen can be encoded by 21 alleles, B*5101-B*5121, we performed HLA-B*51 allele typing as well as HLA class I genotyping of 48 Iranian patients with this disease. As a result, the frequency of the B*51 allele was significantly higher (62.1%) in the patient group as compared with the ethnically matched control group (31.8%) (Pc=0.067, R.R.=3.51). In the genotyping of B*51 alleles, 33 out of the 36 B*51-positive patients possessed B*5101 and the remaining 3 carried B*5108. This study revealed that Iranian patients with BD also had a strong association with HLA-B51. In addition, this significantly high incidence of HLA-B*51 was found to be caused by an increase in both the HLA-B*5101 and HLA-B*5108 alleles. However, there was no significant difference in the HLA-B*51 allelic distribution between the patient and control groups.

The reliability and validity of the 8-item Morisky Medication Adherence Scale (MMAS-8) was assessed in a sample of Iranian hypertensive patients. In this multi-center study which lasted from August to October 2014, a total of 200 patients who were suffering from hypertension (HTN) and were taking anti-hypertensive medication(s) were included. The cases were accessed through private and university health centers in the cities of Tehran, Karaj, Kermanshah, and Bafgh in Iran and were interviewed face-to-face by the research team. The validated Persian translation of the MMAS-8 was provided by the owner of this scale. This scale contains 7 questions with “Yes” or “No” response choices and an additional Likert-type question (totally 8 questions). The total score ranges from 0 to 8 with higher scores reflecting better medication adherence. Mean (±SD) overall MMAS-8 score was 5.57 (±1.86). There were 108 (54%), 62 (31%), and 30 (15%) patients in the low, moderate, and high adherence groups. Internal consistency was acceptable with an overall Cronbach’s α coefficient of 0.697 and test–retest reliability showed good reproducibility (r= 0.940); P< 0.001. Overall score of the MMAS-8 was significantly correlated with systolic BP (r= - 0.306) and diastolic BP (r= - 0.279) with P< 0.001 for both BP measurements. The Chi-square test showed a significant relationship between adherence level and BP control (P= 0.016). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the scale were 92.8%, 22.3%, 52.9%, and 76.7%, respectively. The Persian version of the MMAS had acceptable reliability and validity in Iranian hypertensive patients. This scale can be used as a standard and reliable tool in future studies to determine medication adherence of Persian-speaking patients with chronic conditions. PMID:25946926

There is considerable international interest in the use of performance measurement and their public release in order to improve the quality of care. However, few studies have assessed stakeholders' awareness and use of performance data. Iranian hospitals have been graded annually since 1998 and hospital hotel charges vary by grade, but this system has never been evaluated. We conducted a cross-sectional survey of 104 outpatients at eight Teheran hospitals and 103 general practitioners (GPs) to assess the awareness of and attitudes towards hospital grading system. Only 5.8% of patients (95% CI: 1.3-10.3%) and 11.7% of GPs (95% CI: 5.5-17.9%) were aware of grading results. Patients' awareness was positively associated with their education level (P = 0.016). No patient used the grading results for choosing a hospital and only one GP (1%, 95% CI: 0-2%) reported using hospital grade to influence referral decisions. Patients were more influenced by hospitals' public reputation and that of their specialists. GPs believed that the grading system did not reflect the quality of care in hospitals. When developing performance measurement systems, public release of data should be accompanied by evaluation of its impact on awareness and health-care choices.

Introduction: Pain is the main reason for patients with osteoarthritis (OA) to visit health clinics. Health seeking behaviors indicate unmet patient needs and lack of understanding of OA pain patterns. This study aimed to describe the experiences of Iranian patients with OA and explore their health seeking behaviors and perceptions on pain management related to osteoarthritis. Methods: Using a qualitative approach, data was collected by interviewing 19 patients, 2 family members, and 5 health care providers from the in-patient and out-patient clinics, and physicians' offices. Data saturation was reached after 31 in-depth and semi-structured interviews (five second interviews). Data were analyzed by qualitative content analysis, using comparison, reﬂection and interpretation techniques. The criteria used to enhance rigor included credibility, transferability, dependability, and conﬁrmability. Results: Two main categories and six subcategories emerged from data analysis. The first main category included "adapting to the reality" which had three subcategories: Facing OA pain, seeking health care, and accepting pain as a part of life. The second main category included "behavior fluctuation" with three subcategory of role conflict, responsibility for self-care and, adherence to prescribed treatment versus self-treatment. Conclusion: Care seeking behaviors for chronic pain sufferers are void of cultural, emotional, social and financial situation and patient expectations. Some misconceptions emerged about the health problem and its management, which may lead to negative attitudes toward treatment and therapists and finally lead to non-adherence to treatment. Patients need for education to enhance appropriate health care utilization.

Recurrent aphthous stomatitis (RAS) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. RAS appears to be associated with some human leukocyte antigen (HLA) class II alleles and haplotypes. This study attempts to survey the distribution of HLA-DRB and -DQB alleles among Iranian RAS patients and healthy controls. In order to evaluate the association of HLA-DR and DQ alleles and haplotypes, 54 patients with RAS and 100 unrelated healthy subjects as control group were investigated. Our data indicated that DRB1*13:17, DRB1*15:01, and DRB5*01 were significantly more frequent in RAS patients in comparison to controls. However, DRB3:01allele frequency was higher in the controls compared to the patients. The significantly frequent allele in the patients compared with the healthy subjects was HLA-DQB1*03:02. However, both HLA-DQB1*02:01 and HLA-DQB1*03:01 alleles were most frequent in the healthy individuals rather than the patients. The DRB*04/DQB1*03:01 and DRB*01:01/DQB1*02:01 haplotypes were significantly distributed in healthy subjects compared with patients. However, DRB*07:01/DQB1*03:02 haplotype was found to be significantly frequent in patients than controls. In respect of HLA genes, factors are involved in the incidence of RAS; various HLA-DRB and HLA-DQB1 alleles and the related haplotypes are suggested to be the three main RAS susceptibility factors in our population study.

Background: Psychological profile of inflammatory bowel disease patients is not well studied in Iran. We investigated the psychological status of Iranian patients with ulcerative colitis (UC) and its relationship with disease activity and quality of life (QOL). Materials and Methods: A cross-sectional study was conducted on adult UC patients. The Lichtiger Colitis Activity Index, Hospital Anxiety and Depression Scale, General Health Questionnaire-12, and WHOQOL-BREF, were completed by the patients. Results: From 120 studied patients, 35 (29.2%), 48 (40.0%), and 46 (38.3%) had significant anxiety, depression, and psychological distress, respectively. Anxiety, depression, and psychological distress were strongly correlated with disease activity (r = 0.357 to 0.439, P < 0.01). Disease activity was negatively correlated with all QOL dimensions (r = −0.245 to −0.550, P < 0.01). Anxiety, depression, and psychological distress were also negatively correlated with all QOL domains (r = −0.356 to −0.789, P < 0.01). In the regression models, anxiety was independently associated with active disease (β = 4.150, P = 0.049). Furthermore, disease activity was associated with the physical health (β = −0.371, P < 0.001). For almost all of the QOL domains, depression and psychological distress were independent predictors (β = −0.296 to −0.453, P < 0.001). Conclusion: Anxiety, depression, and psychological distress are highly frequent in UC patients of our society and are strongly associated with disease activity. Depression and psychological distress are important predictors of poor QOL in these patients. Further prospective studies, as well as clinical trials, are warranted in this regard. PMID:26600833

Study Design Psychometric evaluation design. Purpose Psychometric evaluation of a multidisciplinary work-related low back pain predictor questionnaire (MWRLBPPQ) of Iranians patient-care workers based on the social cognitive theory. Overview of Literature Healthcare is one of the professions in which work-related musculoskeletal disorders are prevalent. The chronic low back pain experienced by patient caregivers can negatively impact their professional performance, and patient handling in a hospital is the main cause of low back pain in this population. Methods This was a cross-sectional study carried out in Qom, Iran from July 2014 to November 2014. A MWRLBPPQ based on nine concepts of the social cognitive theory and existing literature regarding chronic low back pain was developed. Ten patient-care workers first completed the questionnaire as a pilot test, allowing the ambiguities of the instrument to be resolved. Exploratory factor analysis was used to confirm construct validity. This questionnaire was distributed among 452 patient-care workers in hospitals located in different geographically areas in Qom, Iran. Cronbach's Alpha was calculated to assess reliability. Results In all, 452 caregivers of patients with mean age of 37.71 (standard deviation=8.3) years participated in the study. An exploratory factor analysis loaded seven concepts of self-efficacy, knowledge, outcome perception, self-control, emotional coping, and self-efficacy in overcoming impediments and challenges in the environment. All concepts were jointly accounted for 50.08% of variance of behavior change. The Cronbach's alpha coefficient showed favorable internal consistency (alpha=0.83), and test-retest of the scale with 2-week intervals indicated an appropriate stability for the MWRLBPPQ. Conclusions The MWRLBPPQ is a reliable and valid theory-based instrument that can be used to predict factors influencing work-related low back pain among workers who lift and transfer patients in hospitals

Rationale. Home health care (HHC) has been developed more than any other industry in the past decade. Conflict between nurse and family can diminish the aid produced to the home care patients. Objective. This research was guidance to explore the nature of conflicts between the patient’s families and nurses in homes of dangerous care patients, in an Iranian context. Methods and results. Using the qualitative comfortable study system and the purposive sampling, 15 participants including 7 nurses (4 males and 3 females) operating in houses and 8 members of family who had a care receiving mechanical ventilation at house, were interviewed during 2013 and 2014. The main sources of conflict were due to nurse expectations, family belief, and personal qualities of nurses. The team guider tried to prevent the conflict by different measures, but in some samples, the conflict arose. Both members of family and nurses accepted the team leader as the judge. At first, he tried to keep the situation stable and gave some notification to the nurse and some descriptions to the members of family. In some samples, that the family could not adapt to the position and efforts to solve the conflict were unsuccessful, the team relation with the family being cut. Conclusion. Home care situation is prone to conflict due to various factors. The mentioned sources of conflict in home trial were changed from the ones of the hospital. Based on these results appropriate interventions suitable for home conditions should be implemented. PMID:28316661

Objective. The aim of this study was to investigate the psychometric properties of the Family Inventory of Resources for Management (FIRM) in a sample of family caregivers of cancer patients. Methods. In this methodological study, construct validity of the FIRM was evaluated by known groups and convergent validity in a convenience sample of family caregivers of cancer patients (n = 104) referred to the outpatient oncology wards of five educational hospitals in Tehran from January to April 2016. Reliability was determined by assessing the internal consistency and stability of the instrument. Results. The known-groups findings showed that there is a significant difference between the scores of the FIRM in family caregivers with different levels of caregiver burden (p < 0.001). Also, the results of convergent validity showed that there is a moderate negative correlation (r = −0.50; p < 0.001) between the total scores of the FIRM and the scores of the caregiver burden inventory (CBI). The FIRM showed a good internal consistency (α = 0.85) and a good stability of the test-retest reliability result. Conclusions. There is a sound psychometric basis for the use of the Persian translation of the FIRM for family studies in the Iranian population. PMID:28127470

Primary immunodeficiency disorders (PID) are a heterogeneous group of diseases, characterized by an increased susceptibility to infections. A total of 930 patients (573 males and 357 females) are registered in Iranian PID Registry (IPIDR) during three decades. Predominantly antibody deficiencies were the most common (38.4%), followed by congenital defects of phagocyte number and/or function (28.3%), other well-defined immunodeficiency syndromes (17.7%), combined T- and B-cell immunodeficiencies (11.0%), complement deficiencies (2.4%), and diseases of immune dysregulation (2.3%). Common variable immunodeficiency was the most frequent disorder (20.8%), followed by chronic granulomatous disease, ataxia-telangiectasia, btk deficiency, selective IgA deficiency, and T-B-severe combined immunodeficiency. The frequency of other PID disorders was less than 50 in number (<5%). There is an increasing trend in recognition of more PID in the recent years. Construction of such registry is not only important for its epidemiological aspect but also for its role in increasing the physician's knowledge about such disorders.

Ankylosing Spondylitis (AS) is a chronic rheumatic disease which mainly involves the axial skeleton. It seems that non-HLA genes, as well as HLA-B27 gene, are linked to the etiology of the disease. Recently, it has been documented that KIRs and their HLA ligands are contributed to the Ankylosing Spondylitis. The aim of this study was to evaluate the KIR genes and their HLA ligands in Iranian AS patients and healthy individuals. The present study includes 200 AS patient samples and 200 healthy control samples. KIR genotyping was performed using the polymerase chain reaction sequence-specific primer (PCR-SSP) method to type the presence or absence of the 16 KIR genes, 6 known specific HLA class I ligands and also, two pseudogenes. Two KIR genes (KIR-2DL3 and KIR2DL5), and among the HLA ligands, two HLA ligands (HLA-C2Lys80 and HLA-B27) genes were significantly different between case and control groups. In addition, we found some interesting KIR/HLA compound genotypes, which were associated with AS susceptibility. Our results suggest that the AS patients present more activating and less inhibitory KIR genes with combination of their HLA ligands than healthy controls. Once the balance of signal transduction between activating and inhibitory receptors is disturbed, the ability of NK cells to identify and lyse the targets in immune responses will be compromised. Accordingly, imbalance of activating and inhibitory KIR genes by up-regulating the activation and losing the inhibition of KIRs signaling or combination of both might be one of the important factors which underlying the pathogenesis of AS.

Background: Type 2 diabetes (T2D) is a multifactorial disease with susceptibility of several genes that are related to T2D. Insulin secretion pathway starts with potassium channels in pancreatic beta cells. KCNJ11 gene encodes ATP-sensitive potassium channel subunits. Some studies suggested that KCNJ11 (E23K) mutation increases the risk of T2D. Therefore, present study was designed to investigate the association between E23K polymorphism of KCNJ11 gene and type 2 diabetes mellitus (T2DM) in the Iranian population. Materials and Methods: The type of study was case-control and 40 unrelated subjects, including 20 healthy controls and 20 diabetic patients were recruited (diagnosed based on American Diabetes Association criteria). Blood samples were used for isolation of genomic deoxyribonucleic acid (DNA). Having extracted the genomic DNA from human blood leukocytes by means of High Pure PCR Template Preparation Kit, PCR-restriction fragment length polymorphism method was used to detect KCNJ11 E23K gene polymorphism. BanII restriction enzyme was used for digestion. Data were analyzed using Chi-square or Fisher exact test or independent t-test, as appropriate. P < 0.05 was considered. Results: We found that the carrier homozygous for KK genotype are susceptible to T2D (0.049) and in patients the frequency of K allele was higher than control subjects (0.048). Conclusion: The present study suggests that KCNJ11 (E23K) gene polymorphism is associated with T2DM. PMID:25625107

Background: Although catalytic properties of different genetic polymorphisms of VKORC1 and CYP2C9 products have been identified, there is limited study available regarding warfarin dose requirement in Iranian patient population. This study investigates the impact of these polymorphisms on 115 patients, referred to Payvand Clinical and Specialty Laboratory for determining the appropriate dose of warfarin. Results of the study may be applicable to individuals who are under warfarin therapy to avoid warfarin resistance or intolerance. Subjects and Methods: PT-INR test was utilized as a screening method. Genotyping were performed for VKORC1 and CYP2C9 using PCR method. Statistical analyses including unpaired t-test or ANOVA and regression were done using SPSS. Results: VKORC1 GA was the most common genotype of VKORC1 allele among the study samples, with a rate of 57.4%. In CYP2C9 variant, 20% and 14.8% of subjects carried CYP2C9*1/*2 and CYP2C9*1/*3 genotyping, respectively. By contrast, the WT *1/*1 genotype was more abundant and dominant. The high frequency of VKORC1 (_1639) GA genotype (57.4%), was significant versus for the rest of the cohort (42.6%). In addition, a significant relationship was found between CYP2C9*1 and drug dose (P>0.021). Conclusion: In this study, samples were characterized by higher frequencies of CYP2C9*1 and VKORC1 G/A, determined as higher warfarin taking doses. The results showed a significant relationship of the VCORC1 and CYP2C9 polymorphisms with warfarin sensitivity and severe side effects. Estimating right doses of warfarin to prescribe can help to reduce the risk of over- or under-anticoagulation and subsequently, the risk of thromboembolism or bleeding. PMID:26865929

Terminal complement complex and S protein were searched for in term placentae obtained from 13 women with normal pregnancy and 15 patients with moderate or severe form of pre-eclampsia. Terminal complement complex was found to localize in the fibrinoid material of the decidua of the basal plate, in the stroma of the chorionic villi and in the vessel walls, as subendothelial deposits. S protein had a quite different distribution, being detected in the syncytiotrophoblast located both in the chorionic villi and in the decidua of the basal plate (DBP) and also on the endothelial cells of fetal stem vessels. Mild deposits of C3 were found in the decidua of the basal plate and also in the stroma and on the basal membranes of the villi. Reactivity for C9 neoantigen was also observed in the cytoplasm of some cells, which were recognized to be macrophages by the presence in their cytoplasm of acid phosphatase and by their reaction with a monoclonal antibody specific for macrophages. Differences in complement deposition in normal and pre-eclamptic placentae were essentially quantitative. Possible mechanisms of complement activation are discussed.

Preeclampsia is characterized by a generalized vasoconstriction and increased vascular sensitivity to angiotensin II. Intracellular free calcium, implicated in vascular smooth muscle contraction, has been found to be elevated in platelets of other hypertensive disorders. We therefore measured intracellular free calcium concentrations by using the fluorescent probe quin-2 in platelets of six patients with preeclampsia and compared them to measurements in ten normotensive pregnant women and ten age-matched nonpregnant women. Intracellular free calcium was also determined in the preeclamptic women after delivery. We found that intracellular free calcium was slightly elevated in normal pregnancy (102 +/- 13 nmol/L v 87 +/- 17 nmol/L) but was markedly increased in preeclampsia (138 +/- 13 nmol/L, P less than .05). This increase disappeared six weeks after delivery (84 + 10 nmol/L, P less than .01). To investigate whether the increased intracellular free calcium was related to angiotensin II, the platelets were exposed to thrombin and angiotensin II in vitro. Exposure to thrombin and angiotensin II caused a dose-dependent increase in intracellular free calcium. The intracellular response to thrombin was not significantly different in the three groups. However, stimulation with angiotensin II revealed an increased response in intracellular free calcium in preeclampsia (P less than .05) that disappeared after delivery. Our findings show a sustained increase in platelet intracellular free calcium in preeclampsia and suggest a functional alteration of the angiotensin II receptor in this disease.

Context Cancer is a major cause of death in children under 15 years of age. Aims This study aimed to evaluate relationship between demographics and dental status in a defined group of Iranian paediatric patients undergoing cancer therapy. Settings and Design This cross-sectional study was accomplished on 161 subjects age ranging 8-12 years. There were 76 cancerous patients hospitalized at Mahak Hospital (one of the major children’s cancer centers in Tehran) as the study group and 85 healthy children attending at Dental School, International Branch of Shahid Beheshti University of Medical Sciences, Tehran, Iran from 2012 to 2013. Materials and Methods Demographics were gathered by using data-form. Oral examination and DMFT Index were used to describe teeth status in all teeth and in the first permanent molars. According to Becker’s definition, “D” stands for untreated decayed teeth, “M” indicates missing teeth, and “F” shows Filled teeth. It is noteworthy that full coverage crowns are considered as “F” in this Index. Statistical Analysis Chi-square, Mann-Whitney U, Student’s t-tests and Logistic Regression were used for data analysis. Results The most frequent type of cancer was acute lymphoblastic/lymphocytic leukemia (33.3%). Patients were significantly shorter than controls (p=0.03), and their fathers and mothers were of lower educational achievement (p=0.01, p= 0.001). Although DMFT of all dentition showed significantly higher score in cancerous children (p=0.001), DMFT of four first permanent molars (left, right, upper, and lower) was borderline significantly higher in patients (p= 0.06). Moreover, frequency of cancer was borderline significantly higher in children with lower birth order (p= 0.05). According to Logistic Regression, in as much as patients grew elder 1 year, DMFT index increased 1.5 units. Conclusion Patients under cancer therapy were shorter than healthy ones, and their parents were of lower educational levels. In addition

Objective We aimed to investigate the clinical and para clinical manifestations of neuro metabolic disorders, in patients who presented by neuro developmental delay in their neuro developmental milestones. Materials & Methods The patients diagnosed as neuro developmental delay and regression with or without seizure at the Neurology Department of Mofid Children Hospital in Tehran, Iran between 2004 and 2014 were included in our study. These patients diagnosed as neuro developmental delay by pediatric neurologists in view of diagnostic /screening neuro developmental assessment tests. The patients who completed our inclusion criteria as neuro metabolic disorders were evaluated in terms of metabolic and genetic study in referral lab. Results Overall, 213 patients with neurometabolic disorders were diagnosed. 54.3% of patients were male. The average age of patients was 41 +-46.1 months. 71.4% of parent’s patients had consanguinity of marriages. Eighty seven percent of patients had developmental delay (or/and) regression. 55.5% of them had different type of seizures. Overall, 213 patients with 34 different neurometabolic disorders were diagnosed and classified in the 7 sub classes, consisting of: 1- organic acidemia and aminoacidopathy (122 patients), 2-storage disease (37 patients) 3- eukodystrophy (27 patients), other classes consisted: lipid oxidation disorders, urea cycle disorders, progressive myoclonic epilepsy; and peroxizomal disorders (27 patients). Conclusion In patients with developmental delay or regression, with or without seizure, abnormal neurologic exam along with positive family history of similar disorder or relative parents, abnormal brain imaging with specific patterns, neurometabolic disorders should be considered as one of the important treatable diseases PMID:27375759

Background: As a major factor in patient-centered care, patient education has a great impact on the quality of care provided by nurses; however, clinical nurses’ performance with regard to patient education is not satisfactory. This study is an attempt to investigate barriers and facilitators in patient education from nurses’ point of view. Methods: 122 nurses at Jahrom University of Medical Sciences participated in this descriptive-cross sectional study. Sampling was based on the census method. The questionnaire used to collect data included questions about nurses’ demography, barriers (10 questions), and facilitators (10 questions) in patient education. The questionnaire was designed to be completed independently. To analyze the data, the researchers used descriptive statistics, including frequency, mean and standard deviation. Results: The highest scores related to barriers to patient education were: nurses’ insufficient knowledge, patients’ physical and emotional unpreparedness, and lack of a proper environment for education. The most important facilitators, on the other hand, were: enhancement of instructing nurses’ knowledge and skills, motivating nurses, and a step-by-step approach to patient education. Conclusion: It is important that nurses be prepared and motivated to train their patients. By satisfactory patient education on the part of nurses, patients will be more willing to cooperate in the treatment process. PMID:26156926

Bone disorders have emerged as a worrisome complication in HIV-infected patients in recent years. It is not clear that HIV infection itself or antiretroviral treatment or both are causes of bone loss. However, most studies have found a high prevalence of osteopenia and osteoporosis in HIV/AIDS patients. The objectives of this study were to determine the prevalence of osteopenia and osteoporosis in HIV-infected patients either untreated or receiving Highly Active Antiretroviral Therapy as compared with HIV negative persons. We also assessed the factors associated with these conditions. Bone Mineral Density was assessed by Dual Energy X-Ray Absorptiometry scans at the hip and lumbar spine in 36 AIDS patients receiving antiretroviral therapy and 44 HIV infected patients not receiving antiretroviral therapy (naïve patients) and 40 HIV negative individuals as control. Factors that affect BMD were also determined. Prevalence of osteopenia or osteoporosis in different regions was significantly higher in HIV/AIDS patients compared with HIV negative subjects (77.3% in HIV positive naïve patients, 86.1% in HAART-treated patients and 60% in the control group, P=0.002). Mean serum alkaline phosphatase was higher in HIV/AIDS patients than the control group (P=0.003). Osteopenia and osteoporosis in HIV-infected patients were associated with duration of HIV infection (P<0.0001) and antiretroviral treatment (P=0.012). Prevalence of osteopenia and osteoporosis in HIV/AIDS patients was higher than HIV negative individuals. Osteopenia and osteoporosis in HIV/AIDS patients was associated with duration of HIV infection and antiretroviral treatment.

Formerly preeclamptic women are at risk for cardiovascular disease. Low plasma volume may reflect latent hypertension and potentially links preeclampsia with chronic cardiovascular disease. We hypothesized that low plasma volume in normotensive formerly preeclamptic women predisposes to hypertension. We longitudinally studied n=104 formerly preeclamptic women in whom plasma volume was measured 3 to 30 months after the preeclamptic pregnancy. Cardiovascular variables were assessed at 2 points in time (3-30 months postpartum and 2-5 years thereafter). Study population was divided into low plasma volume (≤1373 mL/m(2)) and normal plasma volume (>1373 mL/m(2)). Primary end point was hypertension at the second visit: defined as ≥140 mm Hg systolic or ≥90 mm Hg diastolic. Secondary outcome of this study was change in traditional cardiovascular risk profile between visits. Variables correlating univariately with change in blood pressure between visits were introduced in regression analysis. Eighteen of 104 (17%) formerly preeclamptic women who were normotensive at first visit had hypertension at second evaluation 2 to 5 years later. Hypertension developed more often in women with low plasma volume (10/35 [29%]) than in women with normal plasma volume (8/69 [12%]; odds ratio, 3.2; 95% confidence interval, 1.4-8.6). After adjustments, relationship between plasma volume status and subsequent hypertension persisted (adjusted odds ratio, 3.0; 95% confidence interval, 1.1-8.5). Mean arterial pressure at second visit correlated inverse linearly with plasma volume (r=-0.49; P<0.01). Initially normotensive formerly preeclamptic women have 17% chance to develop hypertension within 5 years. Women with low plasma volume have higher chance to develop hypertension than women with normal plasma volume. Clinically, follow-up of blood pressure seems warranted in women with history of preeclampsia, even when initially normotensive.

Occult HCV infection is a form of chronic HCV infection characterized by absence of detectable anti-HCV antibodies or plasma HCV-RNA but presence of HCV-RNA in liver biopsy and/or peripheral blood mononuclear cells (PBMCs). The aim of this study was to determine the presence of HCV-RNA in PBMCs of patients with lymphoproliferative disorders. One hundred and four consecutive patients with lymphoproliferative disorders admitted to Firouzgar Hospital from January 2010 to March 2011 were recruited in this cross-sectional study. A 6-ml sample of whole blood was taken from the patients, the total RNA was extracted from the samples after the separation of plasma and PBMCs. The HCV-RNA of the samples was amplified by reverse transcriptase-nested polymerase chain reaction (RT-nested PCR). The HCV genotypes of the positive samples were tested using the INNO-LiPA™ HCV II kit, and the HCV genotypes were then confirmed by sequencing of the 5'-UTR fragments after the PCR products were cloned into a pJET1.2/blunt cloning vector. The mean age of the patients was 48.3 ± 1.76 years (range: 16-83). HCV-RNA was found in PBMCs from 2 (1.9%) of the 104 patients. Genotyping showed that the patients were infected with HCV subtype 1a. One patient suffered non-Hodgkin's lymphoma and the other suffered chronic lymphocytic leukemia. Patients with lymphoproliferative disorders with negative anti-HCV antibodies and negative plasma HCV-RNA may have occult HCV infection. Therefore, in the absence of a liver biopsy, the testing of PBMCs for the detection of genomic HCV-RNA may be beneficial.

This study aimed to examine the relationship between religious practices and self-care of patients with type 2 diabetes. A descriptive cross-sectional survey was conducted on 154 diabetic patients who were referred to two general teaching hospitals in Qom City (Iran). Data were collected using demographic questionnaire, private and public religious practices, and summary of diabetes self-care activities questionnaires. Data were analyzed using descriptive statistics and statistical tests including independent t test, and Pearson correlation coefficient. Significant positive correlations were observed between religious practices and self-care activities in diabetic patients (p < 0.05). Significant positive correlations were also found between some religious practices and self-care activities subscales (p < 0.05). Healthcare providers should be aware of the role that religion plays in the lives of diabetic patients and be able to take religious factors into account when developing care plans. Doing so will enhance a more patient-centered approach and thereby support patients in their role as self-care decision-makers.

Nurses’ care quality for patients in the ICU depends on their degree/level of hope to improving patient, but there is no consensus on the concept “hoping to improve patient.” The purpose of the present study is to analyze the concept nurses hoping to improving patient in the ICU. To analyze this concept, hybrid model is used which consists of theoretical phase, field work phase, and final analytical phase. In field phase work, semi-structured, face to face and individual interviews were done for nurses working in the ICU, and the data gathered from the interviews were analyzed using inductive content analysis. In theoretical phase, the concept hoping to improve patient was characterized by being available, being professional, expecting positively, and being future- oriented. The scientific definition of this concept was explained through properties which are necessary for qualified nursing care. In field work phase, the categories include nursing care, inner feeling, belief and consequences. In final analytical phase, final definition of the concept was explained through properties such as dynamic expectation, being realistic, and being goal- oriented which is a better function and attitude in effective nursing care accompanying peace of mind for nurses. Concept analysis showed that nurse’s awareness of hoping to improve patient helps the nurse do his job in the best way and with peace of mind. PMID:25363116

Background Cardiovascular patients need information to preserve and promote their health, but not all of them have the necessary motivation to seek relevant health knowledge. Objectives The present study analyzed experiences of patients, family caregivers, and healthcare providers to explore the motivating factors that cause cardiovascular patients to seek important health information. Patients and Methods This study was conducted using a qualitative approach and conventional qualitative content analysis method. Thirty-six people, including 18 cardiovascular patients, 7 family caregivers, and 11 healthcare providers (from multidisciplinary backgrounds) participated in the study. The data were collected through semi-structured interviews and purposeful sampling and continued until data saturation. Data collection and analysis proceeded simultaneously and with constant comparison; this study was carried out from May 2012 to May 2013. Results During the analysis process, three main themes were extracted that characterized participants’ experiences, perceptions, and motivations to seek health information. The themes were “Optimizing quality of life, “Desire for personal rights to be respected,” and “Gaining confidence through consultation.” Conclusions Our findings showed that, through seeking information, patients try to achieve well-being and realize their personal rights as well as their right to security. They should also be encouraged to enhance their quality of life by using the Knowles’ learning theory to formulate their needs and learning priorities. PMID:27437128

Aim: Spiritual well-being is known as a main resource for adjustment and coping when confronted with stressful situations such as managing a chronic disease. The aim of this study is to determine the very relationship between spiritual well-being and quality of life in hemodialysis patients. Methods: A convenience sample of 95 patients with end-stage renal disease who were referred to main hemodialysis centers were included from December 2012 to June 2013. Data was collected by using a socio-demographic questionnaire, the SF-36 quality of life scale, and the spiritual wellbeing scale. Descriptive analysis, Pearson’s correlation and logistic regression analysis were performed for statistical assessment. Results: The mean age of the patients evaluated was 50.4 (SD=15.72) years of age, and 61.1% of the patients were male. Both religious and existential domains of spiritual wellbeing were associated with bodily pain, vitality, social functioning and mental health (P<0.05). The results of multiple logistic regression showed that religious well-being was associated with better quality of life in both domains of physical (OR=1.17; p=0.01) and mental (OR=1.14; p=0.02) components after controlling for socio-demographic and clinical variables. Conclusion: Religious well-being should be considered important predictive factors for the better quality of life in hemodialysis patients. This indicates the need for psychosocial and spiritual supports in the care of these patients. PMID:24999150

Behçet’s disease (BD) is a complex chronic relapsing inflammatory disorder of unknown etiology. Alterations of the tumor necrosis factor (TNF) expression related to the polymorphic alleles of TNF gene may implicate a pathogenetic role in increased activity of this cytokine in BD. A current study aimed at investigating the possible association between BD and its clinical features in Iranian Azeri Turks with two functional TNF-α gene polymorphisms (at the positions of -238 and -857). A total number of 166 Iranian subjects were enrolled into two different groups; patients with BD (n = 64), and ethnically matched healthy controls (n = 101). The genotype distributions of BD patients and healthy controls were determined. The frequency of TNF-α -857C allele was significantly higher in Behçet’s patients than that of healthy controls (P = 0.001; odds ratio [OR] = 2.616; 95% confidence interval [CI] = 1.129–6.160), whereas the frequency of TNF-α -238A allele was similar in both groups. The sole TNF-α haplotype-857C-1031C, was associated with an increase in the risk of developing BD. The TNF-α -857C allele was considerably associated with BD in this cohort. The findings of this study, collectively, indicate that TNF-α -857C-1031C haplotype located in the promoter region of the gene could exert major influence on the susceptibility to BD. PMID:27914129

Background and aims. The aim of the present study is to determine the incidence of MTHFR C677 T and A1298C muta-tions in Iranian patients with cleft lip and/or cleft palate. Materials and methods. We screened 61 Iranian patients with cleft lip and/or cleft palate for mutations in the two alleles of MTHFR gene associated with cleft lip and/or palate: A1298C and C677T, using Polymerase Chain Reaction following by RFLP. Results. The 677T and 1298C homozygote genotypes showed a frequency of 36.1% and 11.4%, respectively. Combined genotype frequencies in newborns having oral clefts showed that the highest genotype was 677TT/1298AA (22.9%) and 677TT/1298CC genotypes were not observed. Conclusion. The results showed that 65.6% of all patients had at least one T mutant allele in C677T and 58.9% C mutant allele for A1298C. According to the frequencies of homozygosity of mutant alleles, it could be said that MTHFR genotype of 677TT shows a greater role in having oral clefts. PMID:26236436

Due to lack of sufficient data on characteristics of breast cancer patients and risk factors for developing metastasis in Iran this study was designed to understand clinical aspects impacting on survival. A cross-sectional study on breast cancer patients was conducted in an oncology clinic of the university hospital between 1995 and 2010. Data were retrieved from medical records and included age, menopausal status, tumor diameter, number of involved nodes, histopathological type, estrogen and progesterone receptor expression, c-erbB-2, primary and secondary metastasis sites, overall survival, disease free interval and type of chemotherapy protocol. The results were analyzed with SPSS 13 software.The mean age of the patients was 49.2 (27-89) years. The primary tumors were mainly ER positive (48%) and PR negative (49.3%). The status of lymph nodes dissected and examined in these patients was unknown in 19 patients (25.3%) while 18 patients (24%) had positive lymph nodes with no report on the number of involved nodes. All of the patients had received antracyclin based chemotherapy in an adjuvant or metastatic setting. Adjuvant hormonal therapy was administered to receptor positive patients. In average, overall survival after recurrence was 30 months (95%CI 24.605-35.325) for non-skeletal versus 42 months (95%CI 31.211-52.789) for skeletal metastasis (P= 0.002). The median survival was also greater for receptor positive patients; 39 months (95%CI 33.716-44.284) for PR+ versus 26 months (95%CI 19.210-32.790) for PR- (P=0.047) and 38 months (95%CI 32.908-43.092) for ER+ versus 27 months (95%CI 18.780-35.220) for ER- patients (P=0.016). No relation was found between site of first metastasis and hormone receptor, age, tumor diameter, DFI and menopausal status. Sites of metastasis were independent of age, size of the tumor, menopausal and hormone receptor status in this study. Overall survival provided significant relations with respect to receptor status and bone

Background: Admission to an Intensive Care Unit (ICU) is recognized as a situation with emotional strain, uncertainty, and fear of losing the patient. In such stressful situations, it is hope that can promote psychological stability in the patient's family members. Related literature revealed that sources of hope in this situation have still not been discussed well in studies. The purpose of this qualitative study was to explore the sources of hope from the perspective of families of ICU patients in Iran. Materials and Methods: In this qualitative study that was carried out adopting the conventional qualitative content analysis approach, 19 family members of 13 patients hospitalized in the ICU from three teaching hospitals were selected, through purposive sampling. Semi-structured interviews were used for data collection. The interviews were transcribed verbatim and analyzed using conventional content analysis, through the process of data reduction and condensation, coding, and also generating categories and subcategories. Results: Analysis of the data revealed sources of hope in families of ICU patients. These sources appeared as two main categories- internal sources and external sources. The internal sources had two subcategories consisting of ’religious-spirituality beliefs’ and ’positive attitude’. The external sources had four subcategories consisting of healthcare professionals’ interactions, empathy of families and friends, patient's condition, and participation in care. Conclusions: The results of this study showed the sources of hope in the families of the patients in the ICU. These sources, as moderating factors, could reduce physical and psychological damages caused to the families. In the present study, the categorizations of the participants’ in-depth experience could develop a new horizon for healthcare professionals, especially nurses, on the sources of hope, based on culture.

Background: Covalently closed circular DNA (cccDNA) of hepatitis B virus (HBV) is a marker of HBV replication in the liver of patients infected with HBV. Objectives: This study aimed to investigate the association between the presence of cccDNA in the plasma samples of Iranian treatment-naive patients with chronic hepatitis B infection and HBV viral load and HBsAg levels. Patients and Methods: From April 2012 to May 2015, 106 treatment-naive patients with chronic hepatitis B infection were enrolled in this cross-sectional study. The HBsAg titer was measured by the Roche HBsAg II assay on the Cobas e411 system, and HBV DNA quantitation was performed using the COBAS TaqMan 48 kit. Real-time polymerase chain reaction was performed for the detection of HBV cccDNA. Results: The mean (SD) age of the patients was 41.1 ± 12.4 years (range, 20 - 62 years). From a total of 106 study participants, 67 (63.2%) were males. The HBV cccDNA was detected in plasma specimens in 19 (17.9%) out of the total 106 patients, and a significant relationship was found between the presence of cccDNA in plasma sample of males (23.9%) and females (7.7%) (P = 0.039). Also, a significant correlation was found between the presence of cccDNA in plasma sample of the patients and HBV viral load level (P < 0.0001) and HBsAg titer (P = 0.0043). Conclusions: This study showed that cccDNA can be detected in the plasma specimen of 17.9% of Iranian treatment-naive patients with chronic hepatitis B infection. Therefore, designing prospective studies focusing on the detection of cccDNA in these patients would provide more information. PMID:26504471

Background: Recurrent breast cancer (BC) after initial treatments is usually associated with poor outcome. The objective of this study is to evaluate baseline characteristics of BC patients to determine their prognostic influence of recurrences. Materials and Methods: In this retrospective study of 481 BC patients, 182 patients who had recurrence within the first, second, or third 5 years after diagnosis were included in the study. The significant prognostic factors associated with late or very late recurrence were selected according to the Akaike Information Criterion. Early recurrence was defined as initial recurrence within 5 years following curative surgery irrespective of site. Likewise, late recurrence was defined as initial recurrence after 5 years. Also, very late recurrence was defined as initial recurrence after 10 years. Results: During the follow-up period, 182 recurrences occurred (local recurrence or distant metastasis). All patients were treated with chemotherapy and radiotherapy and the patients with estrogen receptor (ER)- or progesterone receptor (PR)-positive had hormone therapy. There was a significant correlation between histological grade and receptors status with recurrence. In binary logistic regression analysis, ER and PR were significant prognostic factors for early recurrence. Conclusion: High histological grade and immunohistochemical markers (ER- and PR-negative or human epidermal growth factor receptor 2-positive) are risk factors for recurrence, especially in early recurrence and also between of them, ER is the more significant prognostic factor in early recurrence.

Background Intravenous opioids are administered to prevent and control hemodynamic changes due to endotracheal intubation. Except for special cases such as preeclampsia, these drugs are not recommended for parturants candidate for cesarean section because of the respiratory depression caused in the newborn. Objectives According to rapid metabolism of remifentanil, the current study aimed to compare hemodynamic changes in preeclamptic parturants who received remifentanil and fentanyl for cesarean section under general anesthesia. Patients and Methods This single blind randomized clinical trial was performed on preeclamptic pregnant women candidate for cesarean section under general anesthesia. They were divided into two groups. In the first group 0.05 μg/kg/min remifentanil was infused for 3 minutes before induction of anesthesia and in the second group 1ml (50 μg) fentanyl was injected before induction. Heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) before and after intubation and also Apgar index were measured and compared between the two groups. Results All hemodynamic variables increased after intubation in the fentanyl group (pSBP = 0.146, pDBP = 0.019, pHR < 0.001). Additionally, decrease in SBP (P = 0.018) and DBP (P = 0.955) and mild increase in HR (P = 0.069) after intubation in the remifentanil group was observed. No significant difference was found between Apgar indexes of the two groups (P = 0.771). Conclusions It can be postulated that remifentanil can be used in partituents candidate for cesarean delivery under general anesthesia to prevent severe increase in blood pressure and heart rate during tracheal intubation without adverse effects on newborn.

ABSTRACT Background: Although Implantable Cardioverter Defibrillator (ICD) saves the life of patients with life-threatening ventricular dysrhythmias, it causes various challenges in their life span. Considering the increase in the number of ICD users, more knowledge is required regarding changes in the patients’ life after device implantation. The aim of this study was description of changes in daily life of patients after ICD implantation Methods: This qualitative study was conducted through content analysis method. The participants were selected through purposive sampling. They included 3 women and 9 men whose ages ranged from 24 to 74 years, with the mean age of 42.58+1.55 years. They had implanted ICDs in order to treat life-threatening dysrhythmias. The study data were collected through interview and field notes from November 2013 to October 2014. The data were simultaneously analyzed using constant comparative analysis. Results: Through analysis of the study data, 2 categories were emerged representing dimensions of changes in daily life of the patients with ICD. These categories were changes in the social role and familial challenges after implantation. Change in social role included the following subcategories: “Change in manifestation of routines”, “Shift in leisure time”, “Change in job and education status”, and “Change in interaction between the patient and society members”. In addition, familial challenges after implantation consisted of 2 subcategories, namely “Difficulty in marriage” and “ICD implantation and a range of familial changes”. Conclusion: The study findings can be of great importance in nurses’ clinical practice for providing the patients with holistic care, education, support, and follow-up. They can also be used as a guide assisting clinical treatment of the patients with ICD.

Objective To detect the serum levels of folate and B12 in both preclamptic and normotensive pregnant women and to determine whether there is any relation between these levels with the uterine and umbilical artery Doppler indices as well as the pregnancy outcome. Material and Methods This case controlled study comprised 79 pregnant patients with preeclampsia and 113 healthy, normotensive pregnant women with singleton pregnancies at gestational ages ranging from 34–40 weeks. Patients were not obese (BMI<30) and did not suffer from chronic hypertension, chronic renal or liver disease nor diabetes mellitus. Serum folate and B12 were detected in all cases. They were also subjected to a Doppler study of both the uterine and umbilical arteries. Serum folate and B12 blood levels as well as the Doppler study indices (RI and PI) were compared in both groups. Results The serum folate level was significantly lower in preeclamptic patients than normal pregnant women (p<0.001). It was significantly correlated to uterine artery Doppler indices (RI and PI) and negatively correlated to umbilical artery Doppler indices (RI and PI). Low serum folate was significantly correlated to poor maternal outcome. Low serum folate was also significantly correlated to poor perinatal outcome. Serum B12 level was not significantly different in preeclamptic patients from the control group (P value=0.14). Conclusion Serum folate was significantly lower in preeclamptic pregnant women with a significant correlation to increased uterine and umbilical RI, PI and poor maternal and neonatal outcome.

There are inconsistent findings about the role of Blastocystis infection in irritable bowel syndrome (IBS). The present study was aimed to determine the frequency of Blastocystis and their subtypes (ST) in patients with IBS. A total of 122 patients with IBS and 122 healthy individuals referred to the medical laboratory centers in Ahvaz (southwest of Iran) participated in the study. The frequency of Blastocystis was determined. Blastocystis genomic DNA was extracted from positive feces, and PCR was performed using seven primer pairs targeting the SSU rDNA gene. Blastocystis was detected in 19.67% of patients with IBS and 17.2% of individuals without IBS. The difference between two groups was not statistically significant (P=0.3). Among the five subtypes of Blastocystis, ST3 was more common in patients with IBS and control group. However, there were no significant differences between two groups in terms of subtypes of Blastocystis (P=0.6). It seems, the role of Blastocystis in the etiology of IBS should be further investigated. Furthermore, a model of study should be designed to investigate the role of host factors in severity of parasitic disease.

Nonpharmacological methods of pain relief such as acupressure are becoming increasingly popular worldwide. Practitioners often claim that such methods are highly effective and less invasive than analgesic drugs, but available empirical evidence is largely inconclusive. This study aimed to test the hypothesis that, postacupressure intervention, the amount of pain experienced by sampled leukemia patients, who received acupressure in addition to standard care, will reduce substantially compared to patients who received only routine treatment. This controlled trial was undertaken with hospitalized leukemia patients between February and June 2015. Our primary sample consisted of 100 participants who were randomly allocated to 2 groups. One (intervention) group underwent 12 acupressure sessions in addition to standard treatment while the control group received no intervention apart from being given the standard treatment for leukemia. The visual analogue scale was used to measure the levels of pain experienced. No significant differences were found between the 2 groups across 12 interventions. However, each group reported significantly different pain level changes before and after each intervention, suggested that the acupressure method was effective in reducing pain in the short term. Nurses are able to apply this complementary therapy alongside other procedures to manage these patients' pain. It is recommended that further studies be conducted to better understand the specific conditions under which acupressure can provide effective pain relief.

As cytokines, including interleukin-4 (IL-4), seem to have a pivotal role in the pathogenesis of juvenile idiopathic arthritis (JIA), this study is aimed at investigating of association of polymorphisms in IL-4 and IL-4 receptor α (IL-4RA) genes with susceptibility to JIA. A case-control study was conducted on 53 patients with JIA and 139 healthy unrelated controls. Single nucleotide polymorphisms of IL-4 gene at positions -1098, -590, and -33, as well as IL-4RA gene at position +1902 were genotyped using polymerase chain reaction with sequence-specific primers method and compared between patients and healthy individuals. At the allelic level, C allele at IL-4 -33 was found to be more frequent in patients compared to control (P value <0.01). At the genotypic level, CC genotype at IL-4 -590 (P value <0.01), together with CC and TT genotypes at IL-4 -33 (P value <0.01), were significantly higher in patients with JIA, while TC genotypes at IL-4 -590 and -33 positions were found to be lower in case group (P value <0.01). At the haplotypic level, IL-4 (positions -1098, -509, -33) TTC, GCC, and TTT haplotypes were significantly lower than controls (P value <0.01, P value = 0.03, and P value = 0.04, respectively). Although, TCC haplotype at the same positions was found to be higher in patients (P value <0.01). Polymorphic site of +1902 IL-4RA gene did not differ between cases and controls. Polymorphisms in promoter region of IL-4 but not IL-4RA genes confer susceptibility to JIA and may predispose individuals to adaptive immune responses.

Introduction: Cardiovascular events are the major cause of death in patients with chronic renal failure. About half of dialysis patients because of reduced phosphorus clearance have hyperphosphatemia. Hyperphosphatemia and following secondary hyperparathyroidism lead to some cardiovascular changes. Hemodialysis (HD) partly removes phosphorus during each dialysis session. Objectives: Presented study was designed to evaluate dialyzer variation effect on phosphorus level as a prognostic factor after dialysis using. Materials and Methods: Six kinds of dialyzer were used for dialysis; low flux (LF) dialyzer (F7 and F8), high flux (HF) dialyzer (F70 and F80) and finally hollow-fiber dialyzers including polyethersulfone (PES) 130 HF and polysulfone (PS) 13 LF. Fifty-seven patients were divided into 6 matched groups included three groups of 10 people and 3 groups of 9 persons in groups: A (F70), B (F80), C (F7), D (F8), E (PES 130 HF) and F (PS 13 LF). Patients were treated for one month with these dialyzers. At the end of the month, blood samples were taken again for phosphorus level before dialysis handling. Results: The mean pre-dialysis serum phosphorus was 5.03, 5.4, 5.2, 4.6, 4.95 and 5.1 mg/dl and the mean phosphorus was 5.43, 5.01, 4.9, 4.18, 4.17 and 5.3 mg/dl after one month of dialysis, respectively in groups A to F without any statistically differences between pre- and after one month dialysis values respectively. Discussion: The findings indicate dialyzer type in the control of serum phosphorus has not been effective in the short-term HD. We suggest a study with more duration time. PMID:27471742

Introduction: Rheumatoid arthritis is a chronic autoimmune disorder that leads to joint swelling, stiffness, pain and progressive joint destruction. It is a common disease with prevalence of 1% worldwide that affecting all aspects of patients’ lives. Therefore, this study was conducted to summarize and provide a clear view of quality of life among the patients in Iran through a literature review. Methods: This study was conducted as a literature review over article published between 2000 to 2013, by using data bases comprise of Google scholar, Science Direct, Pubmed, IRANDOC, SID, Medlib, Magiran and by key words: “quality of life”, “rheumatoid arthritis”, “Iran” and their Persian equivalents. Finally 2065 articles assessed and according to the aim of the study are 11 studies synthesized. Extracted results first were summarized in Extraction Table, and then analyzed manually. Results: In reviewed articles rheumatoid arthritis patients’ quality of life was measured by using five different tools, the most important one of them was SF36 questionnaire. Among eight dimensions of SF36 questionnaire, the highest mean according included articles result was social functioning with average score of 63.4 and the lowest for physical limitation (physical role functioning) with score of 43. Overall, mean of eight dimensions was 52.47. The most important factors affecting quality of life were disease severity and pain, depression, income, educational, occupational status, married status, sign of disease, fatigue, anxiety and disease activity scores. Conclusion: The results of the study showed relatively low quality of life of rheumatoid arthritis patients in Iran. Empowering patients by participating them in service delivery process and decision making can improves quality of life and in this regard health care provider must be focused on patient self-care abilities and reinforcing this factor by training them.

Kidney transplantation is the best treatment option for the patients with end-stage renal disease. Viral infections and genetic factors such as HLA-II antigens may affect the kidney transplant outcome. The compatibility of HLA-DRB1 molecules in the survival of kidney transplant is important. Also, the correlation between these molecules and viral infections is significant. The current study investigates the allele frequency of HLA-DRB1 in 41 recipient kidney transplant and 203 normal healthy controls by polymerase chain reaction using sequence specific primers. Moreover the relation between HLA-DRB1 allelic groups and hepatitis B, hepatitis C and cytomegalovirus viral infections was also studied. However statistical analysis of the allele frequencies didn't show any significant association between HLA-DRB1 allelic group distributions or sharing and susceptibility to acute kidney transplant rejection (P > 0.05). Comparing the allele frequencies between HLA-DRB1*14 and DRB1*04 allelic showed a significant difference in controls and patients (P = 0.03 and P = 0.05 respectively). The results of the present study also showed a significant association between possession of HLA-DRB1*07 allele in kidney transplant recipients and hepatitis C virus infection (P = 0.009). In conclusion however the results of the present study did not showed relation between HLA-DRB1 allele's frequencies or sharing and kidney transplantation outcome, the results indicated that HLA-DRB1 alleles may susceptible individuals to renal disease or play a role in susceptibility to viral infection in kidney transplant patients.

Major depressive disorder (MDD) is one the most common mental disorders; it affects about 5-10% of the world population. This study explores the experiences of people with major depressive disorder in Zanjan, Iran. In order to identify recurring themes and patterns in individuals' experiences of major depressive disorder, semi-structured interviews with 18 patients were recorded and transcribed verbatim. The transcripts were then analyzed based on conventional qualitative content analysis. Five main categories emerged. The first category was called emotional paralysis and included the subcategories feeling severely depressed; feeling anxious; feeling impatient and irritable; and having dyshedonia. The second category was disturbance of thinking and was comprised of the subcategories of preoccupation, instable spiritual beliefs, and guilt. Cognitive decline was the third identified category and was further divided into subcategories of frustration, unawareness of the disorder, negative evaluation, indecisiveness, and loss of focus and loss of memory. Another major category was physical illnesses with the subcategories of physical discomfort, sleep problems, appetite disturbance, facial changes, sexual dysfunction, and medical conditions. The final category was failure in life, which had failure in personal affairs, jeopardized interpersonal relations, and unstable work life as subcategories. These findings provide a base for further research in this area. They also have clinical relevance for health care providers working with patients with MDD. Related cultural issues also are discussed.

Helicobacter pylori (H. pylori) infection as a serious problem in both adults and children can induce chronic gastritis, peptic ulcer disease (PUD), and possibly gastric cancer. The aim of the current study was to survey antibiotic resistance and also to determine influence of PPARγ polymorphism in patients with H. pylori infection. During an 11-month-period, 98 H. pylori isolates were collected from 104 biopsy specimens. In vitro susceptibility of H. pylori isolates to 4 antimicrobial agents metronidazole, clarithromycin, amoxicillin and tetracycline were assessed by quantitative method according to European Committee on Antimicrobial Susceptibility Testing (EUCAST) guideline. PPARγ polymorphism was determined using polymerase chain reaction-restriction fragment length polymorphism assay. The frequency of H. pylori infection in our study was 94.2%. In vitro susceptibility data showed that highest level of resistance was related to metronidazole (66.3%), and the majority of H. pylori isolates were highly susceptible to amoxicillin and tetracycline (94.9% and 96.9%, respectively). Genotypic frequencies were 25.5% for CC (Pro12Pro), 40.8% for GC (Pro12Ala) and 33.7% for GG (Ala12Ala). In our study, CG genotype had highest distributions among infected patients with H. pylori. The study suggests that the PPAR-γ Pro12Ala polymorphism could be evaluated as a potential genetic marker for susceptibility to gastric cancer in the presence of H. pylori infection.

Elevated plasmatic levels of lympho-monocyte and platelet microparticles (MPs) have been reported in preeclampsia. Previous studies suggest that MPs could participate in preeclampsia vascular impairment. In this study, we investigated the ex vivo vascular effects of MPs from preeclamptic women on arteries from normotensive pregnant women. Omental arteries were collected from normal pregnant women undergoing cesarean section and incubated during 24 h with MPs from normal pregnant or preeclamptic women. Vascular contraction to serotonin and phenylephrine was studied on a wire myograph with or without pharmacological selective inhibitors of inducible nitric oxide synthase (iNOS) and/or cyclo-oxygenase-2 (COX-2). Expression of iNOS, COX-2, and NF-κB and production of superoxide anion and 8-isoprostane were also assessed by immunohistological or biochemical staining and/or Western blot or ELISA assay, respectively. Microparticles from preeclamptic women, but not those from normal pregnant women, induced hyporeactivity to vasocontracturant agonists in omental arteries. Selective inhibitor of iNOS partially restored this arterial contraction, suggesting that nitric oxide (NO) is involved in vascular contractility alteration. Conversely, COX-2 induced 8-isoprostane release, a vasoconstricting metabolite modulating the agonist-induced contraction. COX-2 selective inhibitor almost abolished the arterial contraction in the same vessels. Interestingly, the association of iNOS and COX-2 selective inhibitors restored the contraction to control levels. Moreover, iNOS, COX-2, and NF-κB expressions are upregulated and superoxide anion levels increased in vessels incubated with MPs from preeclamptic women. In conclusion, circulating MPs from preeclamptic women induce vascular inflammation and enhance oxidative stress. These results suggest a possible role of MPs during preeclampsia-induced arterial dysfunction.

In spite of widespread emergence of aminoglycoside resistance, these drugs are still used in the treatment of staphylococcal infections. This study aimed to investigate the distribution of aminoglycoside resistance and genes encoding aminoglycoside - modifying enzymes (AMEs) as well as Staphylococcal Cassette Chromosome mec (SCCmec) type in coagulase negative staphylococci (CoNS) in pediatric patients. Totally, 93 CoNS isolates were examined for susceptibility to aminoglycosides using disk diffusion and/or E-test methods. AMEs genes and SCCmec types were detected using multiplex PCR. Strain typing was performed using repetitive extragenic palindromic (REP) - PCR assay. The non-susceptibility rates to kanamycin, tobramycin, gentamicin, amikacin and netilmicin were 73%, 59%, 49.5%, 16% and 7.5%, respectively. aac(6')-Ie-aph(2″)-Ia, ant(4')-Ia and aph(3')-IIIa were encountered in 56 (60.2%), 38 (40.8%) and 18 (19.3%) isolates, respectively. In aac(6')-Ie-aph(2″)-Ia- positive isolates, the non- susceptibility rates to kanamycin, gentamicin, tobramycin, amikacin and netilmicin were 83%, 74%, 73%, 49% and 43%, respectively. SCCmec types included type IV (n = 31), I (n = 17), II (n = 5), III (n = 4), and V (n = 2). Three isolates had two types; I + III (n = 2) and III + IV (n = 1) whereas 11 isolates were non-typeable. AMEs genes carriers were distributed frequently into type IV. We found diverse fingerprint patterns among our isolates. In conclusion, there was a strong correlation between alarming rate of aminoglycoside resistance and methicillin resistance. Discordances between phenotypic and genotypic detection of aminoglycoside resistance were discernible. AMEs genes might be related to SCCmec types.

Objective(s): Variation in microsatellite sequences that are dispersed in the genome has been linked to a deficiency in cellular mismatch repair system and defects in several genes of this system are involved in carcinogenesis. Our aim in this study was to illustrate microsatellite DNA alteration in esophageal cancer. Materials and Methods: DNA was extracted from formalin fixed paraffin embedded (FFPE) tissues from surgical and matched margin-normal samples. Microsatellite instability (MSI) and loss of heterozygosity (LOH) were studied in 50 cases of esophageal squamous cell carcinoma (ESCC) by amplifying six microsatellite markers: D13S260 (13q12.3), D13S267 (13q12.3), D9S171 (9p21), D2S123 (2p), D5S2501 (5q21) and TP53 (17p13.1) analyzed on 6% denaturing polyacrylamide gel electrophoresis. Results: Statistical analysis indicated a near significant reverse correlation between grade and LOH (P= 0.068, correlation coefficient= -0.272). Specifically, increased LOH in tumor DNA has a significant correlation with increased differentiation from poorly differentiated to well differentiated tumors (P= 0.002 and P= 0.016 respectively). In addition, higher number of chromosomal loci with LOH showed a reverse correlation with lymph node metastasis (P= 0.026, correlation coefficient= -0.485). Furthermore, there was a positive correlation between addiction and MSI (P= 0.026, correlation coefficient= 0.465). Conclusion: Microsatellite DNA alterations may be a prognostic tool for detection and the evolution of prognosis in patients with SCC of esophagus. It can be concluded that regional lymph node metastasis would be less likely with increased heterozygote loci and addiction with any of opium, cigarette, water pipe or alcohol can be a susceptibility factor(s) for MSI.

Background and Purpose The aim of this study was to determine the face and criterion validity, stability reliability, and internal consistency of the Persian version of the Impact on Participation and Autonomy (IPA-p) scale among Iranian people with multiple sclerosis (MS). Methods Trained experts interviewed 364 MS patients and their relatives to assess the criterion validity, stability reliability, and internal consistency of the IPA-p scale. Ten specialists from different disciplines were also recruited to assess its face validity. A consent form was completed by the patients and their relatives. Internal consistency reliability was measured using Cronbach's alpha and stability reliability was assessed using interclass correlation coefficients (ICCs). The test-retest method was used to detect the reliability of the questioner. The study subjects completed the IPA-p scale on two occasions separated by an interval of 30-45 days. Study checklists were also used to assess the face validity, stability reliability, and internal consistency of the IPA-p scale. Results About 50% of the respondents reported their perceived overall participation to be "good" or "very good" and 60% of the specialists rated the ability of the IPA-p scale to measure what it was designed for as "excellent." Spearman correlation coefficients were >0.8 for all but one IPA-p domain. Cronbach's alpha between the mean IPA-p scale scores achieved on two separate occasions ranged from 0.858 to 0.913. The highest and lowest internal consistencies belonged to the "social relationships" and "education and learning" domains, respectively. The test-retest ICCs for the nine domains were between 0.789 and 0.919, and all were significant at p<0.001. Conclusions The IPA-p questionnaire can be considered a valid and reliable instrument for assessing self-reported participation among Iranian MS patients. PMID:25851894

Breast cancer, with a lifelong risk of one in nine, is the most common cancer among women. In Iran, breast cancer is one of the growing and important women's health problems. Several environmental, genetic and epigenetics factors have been suggested to have a role in breast cancer development. Epigenetics alterations are heritable changes in gene expression that occur without causing any change in DNA sequence. DNA methylation as a main epigenetics modification in human cancer is found as a promising biomarker in early detection of breast cancer. Association between epigenetics changes of many gene promoters with the risk of breast cancer has been investigated worldwide. This aberrant methylation may be occur in specific genes related to cell cycle, cell adhesion, apoptosis and DNA repairing mechanisms and results in silencing of these important genes. In this review study, we have gathered all the data until December 2015 about epigenetics modifications among Iranian population with breast cancer. We searched international web databases such as: PubMed, Scopus, and Persian web databases; IranMedex and Magiran to investigate the association of epigenetics change and incidence of breast cancer among Iranian population. Using "methylation" or "epigenetics" key words and "Iran" as affiliation, all the published data were 31. After arbitrary limitation in search keywords the result have been 20 articles. Data analysis show that "ER-α" and "E-Cadherin" are most common studied genes in epigenetics modifications. Also, maximum studies were done in Tehran and Tabriz. We thought that more studies will be helpful to reveal the relation of methylation status in candidate genes with the breast cancer risk in Iranian populations.

The dihydropteroate sulfate (DHPS) gene is associated with resistance to sulfa/sulfone drugs in Pneumocystis jirovecii. We investigated the DHPS mutation rate in three groups of Iranian HIV-positive and HIV-negative patients by polymerase chain reaction-restricted fragment length polymorphism analysis. Furthermore, an association between P. jirovecii DHPS mutations and strain typing was investigated based on direct sequencing of internal transcribed spacer region 1 (ITS1) and ITS2. The overall P. jirovecii DHPS mutation rate was (5/34; 14.7%), the lowest rate identified was in HIV-positive patients (1/16; 6.25%) and the highest rate was in malignancies patients (3/11; 27.3%). A moderate rate of mutation was detected in chronic obstructive pulmonary disease (COPD) patients (1/7; 14.3%). Most of the isolates were wild type (29/34; 85.3%). Double mutations in DHPS were detected in patients with malignancies, whereas single mutations at codons 55 and 57 were identified in the HIV-positive and COPD patients, respectively. In this study, two new and rare haplotypes were identified with DHPS mutations. Additionally, a positive relationship between P. jirovecii strain genotypes and DHPS mutations was identified. In contrast, no DHPS mutations were detected in the predominant (Eg) haplotype. This should be regarded as a warning of an increasing incidence of drug-resistant P. jirovecii strains.

Background: Anxiety is a concern in obstetrics, especially in preeclamptic mothers. Sedation is not commonly used in parturients for fear of adverse neonatal effect. We investigated maternal and neonatal outcome of midazolam as an adjuvant to spinal anesthesia for elective cesarean delivery. Methods: A prospective randomized controlled trial, in which eighty preeclamptic parturients received either an intravenous dose of 0.035 mg/kg of midazolam or an equal volume of normal saline, 30 min before spinal anesthesia. Maternal anxiety was assessed using Amsterdam Preoperative Anxiety and Information Scale (APAIS); postoperative maternal satisfaction was assessed using Maternal Satisfaction Scale for Cesarean Section (MSSCS). Newborns were assessed using Apgar score, Neonatal Neurologic and Adaptive Capacity Score (NACS), and umbilical artery blood gases. Results: Mothers premedicated with midazolam showed a lower level of preoperative anxiety and a higher degree of postoperative satisfaction than the control group. There were no between-group differences regarding the neonatal outcome. Conclusion: Preeclamptic parturients premedicated with midazolam (0.035 mg/kg) before spinal anesthesia have lower anxiety and higher postoperative satisfaction levels, with no adverse effects on the newborns.

Objective: The purpose of this study was to describe the moral distress among Iranian registered nurses. Methods: This was a descriptive –analytic study, in which 264 out of 1000 nurses were randomly selected as a sample group and completed the questionnaire. The nurses’ moral distress was assessed using Corley’s 30-item Moral Distress Scale adapted for use in an Iranian population. The collected data were analyzed by SPSS version 19. Results: In this study, no correlation was found between the level of moral distress and any of the demographic data. The mean moral distress score ranged from 3.56 to 5.83, indicating moderate to high levels of moral distress. The item with the highest mean score was “working with unsafe levels of nurse staffing”. The item with the lowest mean score was “giving medication intravenously to a patient who has refused to take it”. Nurses working in EMS and NICU units had the highest levels of moral distress. Conclusion: A higher degree of moral distress is observed among nurses who work in health care systems. The results of this study highly recommend practical and research-oriented evaluation of moral distress in the medical society in Iran. Our findings suggest that Iranian version of MDS is a reliable instrument to measure moral distress in nurses. PMID:26005478

Background: Tetralogy of Fallot (TOF), the most common cyanotic heart defect and one of the most common congenital heart diseases, occurs mostly sporadically and nonsyndromically. The underlying molecular genetic mechanism is not known. Therefore, the existence of mutations in the homeodomain-encoding region of NKX2.5 gene in Iranian patients with tetralogy of Fallot is evaluated. Materials and Methods: In the present study, we analyzed the peripheral blood samples of27 patients in order to find any mutation in the 180 bp homeodomain-encoding region of NKX2.5 gene, which is known to be involved in heart development and diseases. DNA was extracted and all the samples were amplified by polymerase chain reaction (PCR) and sequenced. Results: Twenty-seven patients were included in the study. Twenty-five of them were infants and children (6 days to 11 years of age), one was a teenager (14-years of age), and another was a 33-year-old man [mean ± standard deviation (SD): 5.80 ± 3.90 years]. Thirteen patents were males (mean ± SD: 6.587077 ± 5.02 years) and 14 were females (mean ± SD: 5.0726 ± 2.81 years). One synonymous variant, i.e., c.543G>A was identified in one patient. Conclusion: Mutations in the homeodomain-encoding region of NKX2.5 gene may not have an outstanding role in etiology of tetralogy of Fallot patients in Iran. PMID:27904570

The CC chemokine receptor 5 (CCR5) delta 32 allele results in a nonfunctional form of the chemokine receptor and has been implicated in a variety of immune-mediated diseases. CCR5Δ32 may also predispose one to chronic liver disease or be linked with resistance to HBV infection.This study was undertaken to investigate any association between CCR5 polymorphism with resistance to hepatitis B or susceptibility to HBV infection. A total of 812 Iranian individuals were enrolled into two groups: HBV infected cases (n=357), who were HBsAg-positive, and healthy controls (n=455). We assessed polymorphisms in the CCR5 gene using specific CCR5 oligonucleotide primers surrounding the breakpoint deletion. Genotype distributions of the HBV infected cases and healthy controls were determined and compared. The CCR5/CCR5 (WW) and CCR5/ CCR5Δ32 (W/D) genotypes were found in (98%) and (2%) of HBV infected cases, respectively. The CCR5 Δ32/ Δ32genotype was not found in HBV infected cases. Genotype distributions of CCR5 in healthy controls were W/W genotype in (87.3%), W/D genotype in (11.2%) and D/D genotype in (1.5%). Heterozygosity for CCR5/ CCR5Δ32 (W/D) in healthy controls was greater than in HBV infected cases (11.2% vs 2%, p < 0.001). W/D and D/D genotypes were more prominent in healthy controls than in HBV infected cases. This study provides evidence that the CCR5Δ32 polymorphism may have a protective effect in resistance to HBV infection at least in the Iranian population.

Objective(s): FOXP3 gene is an X-linked gene that encodes FOXP3 protein, an essential transcription factor in CD4+CD25+FOXP3+ regulatory T (Treg) cells. We aimed, in the present study, to investigate the association of two FOXP3 polymorphisms, -2383 C/T (rs3761549) and IVS9+459 T/C (rs2280883), with lung cancer. Materials and Methods: In a case-control study we analyzed genotypes and alleles frequencies at -2383 C/T and IVS9+459 T/C positions in 156 patients with lung cancer and 156 age and sex matched healthy controls in Southern Iranian population, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods. The data were verified by direct automated DNA sequencing. Results: The frequency of -2383 T allele was significantly higher in the patients than in the control group (11.8% versus 5.9%, P-value=0.04, OR=2.13, 95%CI=1.04-4.54). T allele frequency at IVS9+459 T/C position was higher, compared to the controls, in the patients who presented the disease over 55 years old (69.9% versus 59.1%, P-value=0.04, OR=1.61, 95%CI=1.01-2.55) and also in SCLC patients (77.8% versus 59.1%, P-value=0.03, OR=2.42, 95%CI=1.05-5.59). No significant differences were found in the genotypes and haplotypes distributions between the cases and controls. A high degree of linkage disequilibrium was observed between two polymorphisms. Conclusion: As the first study dealing with -2383 C/T and IVS9+459 T/C in lung cancer, our data conclusively suggest the association of -2383 T allele with susceptibility to lung cancer in Iranian population. The association of IVS9+459 T allele with susceptibility to lung cancer in old patients suggests the age-dependent effects of FOXP3 gene on cancer occurrence. PMID:26124932

The role of HFE gene mutations or its expression in regulation of iron metabolism of hereditary haemochromatosis (HH) patients is remained controversial. Therefore here the correlation between two common HFE genotype (p.C282Y, p.H63D) and HFE gene expression with iron status in HH, iron deficiency anemia (IDA) and healthy Iranian participants was studied. For this purpose genotype determination was done by polymerase chain reaction--restriction fragment length polymorphism (PCR-RFLP). Real-Time PCR was applied for evaluation of HFE gene expression. Biochemical parameters and iron consumption were also assessed. Homozygote p.H63D mutation was seen in all HH patients and p.C282Y was not observed in any member of the population. A significant correlation was observed between serum ferritin (SF) level and gender or age of HH patients. p.H63D homozygote was seen to be able to significantly increase SF and transferrin saturation (TS) level without affecting on liver function. Our results also showed that iron consumption affects on TS level increasing. HFE gene expression level of IDA patients was significantly higher than other groups. Also the HFE gene expression was negatively correlated with TS. Finally, the main result of our study showed that loss of HFE function in HH is not derived from its gene expression inhibition and much higher HFE gene expression might lead to IDA. However we propose repeating of the study for more approval of our finding.

High resistance to oxidative stress is a common feature of mesenchymal stem/stromal cells (MSC) and is associated with higher cell survival and ability to respond to oxidative damage. Aldehyde dehydrogenase (ALDH) activity is a candidate “universal” marker for stem cells. ALDH expression was significantly lower in decidual MSC (DMSC) isolated from preeclamptic (PE) patients. ALDH gene knockdown by siRNA transfection was performed to create a cell culture model of the reduced ALDH expression detected in PE-DMSC. We showed that ALDH activity in DMSC is associated with resistance to hydrogen peroxide (H2O2)-induced toxicity. Our data provide evidence that ALDH expression in DMSC is required for cellular resistance to oxidative stress. Furthermore, candidate ALDH activators were screened and two of the compounds were effective in upregulating ALDH expression. This study provides a proof-of-principle that the restoration of ALDH activity in diseased MSC is a rational basis for a therapeutic strategy to improve MSC resistance to cytotoxic damage.

Leber's hereditary optic neuropathy (LHON) is an optic nerve dysfunction resulting from mutations in mitochondrial DNA (mtDNA), which is transmitted in a maternal pattern of inheritance. It is caused by three primary point mutations: G11778A, G3460A and T14484C; in the mitochondrial genome. These mutations are sufficient to induce the disease, accounting for the majority of LHON cases, and affect genes that encode for the different subunits of mitochondrial complexes I and III of the mitochondrial respiratory chain. Other mutations are secondary mutations associated with the primary mutations. The purpose of this study was to determine MT-ND variations in Iranian patients with LHON. In order to determine the prevalence and distribution of mitochondrial mutations in the LHON patients, their DNA was studied using PCR and DNA sequencing analysis. Sequencing of MT-ND genes from 35 LHON patients revealed a total of 44 nucleotide variations, in which fifteen novel variations-A14020G, A13663G, C10399T, C4932A, C3893G, C10557A, C12012A, C13934T, G4596A, T12851A, T4539A, T4941A, T13255A, T14353C and del A 4513-were observed in 27 LHON patients. However, eight patients showed no variation in the ND genes. These mutations contribute to the current database of mtDNA polymorphisms in LHON patients and may facilitate the definition of disease-related mutations in human mtDNA. This research may help to understand the disease mechanism and open up new diagnostic opportunities for LHON.

Background: Atorvastatin is prescribed for the primary and the secondary prevention of coronary artery diseases. A wide variation in inter-individual statin response suggests that genetic differences may contribute to this variation. This study investigated the association of ABCB1 (C3435T) and ABCC1 (G2012T) polymorphisms with clinical response to atorvastatin in Iranian primary hyperlipidemic patients. Methods: Individuals (n=179) with primary hypercholesterolemia were enrolled, and peripheral blood samples were collected. Genotyping of two polymorphisms were performed by amplification refractory mutation system PCR. Results: Following four weeks of treatment, a significant reduction of LDL-C was observed in variant groups (CT+TT) of ABCB1 (P=0.018) and wild-type group (GG) of ABCC1 genes (P=0.029). Logistic regression analysis revealed a significant difference between male and female responses to 10 mg/day atorvastatin (P=0.004, odds ratio=0.2, CI 95%=0.06-0.6). Conclusion: Our finding indicated that these polymorphisms may be attributed to LDL-C serum levels in the primary hypercholesterolemia patients receiving atorvastatin. PMID:27238935

The pathogenesis of Bipolar I Disorder (BP-I) involves immune-mediated mechanisms, especially an imbalance in pro-inflammatory/anti-inflammatory cytokines in plasma or cerebrospinal fluid. Interleukin-1 (IL-1) gene cluster, coding some of these pro-inflammatory cytokines, might play a role in various neuropathologies related to neuron inflammation. The aim of the present study was to investigate the possible role of IL-1 gene cluster polymorphisms in determining the susceptibility to BP-I in Iranian population. 48 patients with BP-I in Mashhad (in north-eastern Iran), diagnosed by two psychiatrists using SCID (structured clinical interview for DSM disorders) were selected through convenient sampling and were compared with 47 healthy controls, voluntarily enrolled in the study. Patients with non-Persian ethnicity, history of immunoallergic disorders, endocrinopathies, neurologic disorders, and substance-induced mood disorders were excluded from both case and control groups. Genotyping of IL-1 gene cluster polymorphisms, including IL-1a-889, IL-1b +3954, IL-1b-511, and IL-1RN (VNTR) were carried out using Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and compared by SPSS using Fisher's exact and chi-square tests. The frequency of IL-1b-511 CC genotype and C/T allelic frequency were significantly different between BMD patients and healthy controls (p=0.04 and p=0.02, respectively). Among patients, -511 T allele was significantly more frequent in those with a positive history of major depression. Moreover, +3954 T allele was significantly more frequent in early onset BMD patients. The results suggest a positive association between IL-1 gene cluster variation and BP-I. This polymorphism may contribute to genetic vulnerability through its possible role in neuron inflammation.

Background Molecular studies have demonstrated that the hepatitis C virus (HCV) genotype and host genetics play predictive roles in the management of patients infected with HCV. Objectives This study aimed to investigate the HCV genotype, core amino acid (aa) 70 substitution, and polymorphisms near the IFNL3 gene (including rs12979860 and rs8099917) among Iranian patients with chronic hepatitis C (CHC). Patients and Methods In this cross-sectional study, the molecular profiles of the HCV genotype, core aa 70 substitution, and rs12979860 and rs8099917 polymorphisms and plasma HCV RNA levels were determined in 429 CHC patients including 141 hemophilic, 84 thalassemic, and 204 non-hemophilic, non-thalassemic patients. Results The hepatitis C virus subtype 1a was the most common subtype in the study population. Core aa substitution Arg70Gln was strongly associated with cirrhosis (OR = 2.49; 95% CI = 1.13 - 5.50; P = 0.020). Core aa 70 substitutions were more frequently observed in patients with the HCV subtype 1b than in patients with any other HCV subtypes (P < 0.001). Core aa 70 substitutions were also more common in patients with the rs12979860 TT genotype than in patients with non-TT genotypes (17.3% vs. 8.5%, P = 0.022) and also in rs8099917 non-TT genotypes than in the TT genotype (14.0% vs. 7.0%, P = 0.026). The HCV genotypes and rs8099917 polymorphisms were correlated in which HCV subtype 1b was in favor of rs8099917 GG and HCV subtype 3a favored rs8099917 TT (P = 0.021). Furthermore, the rs12979860 TT and rs8099917 GG genotypes showed significantly lower HCV RNA levels than the other genotypes (P < 0.001). Conclusions There is an as yet unexplained association between HCV and host parameters with unknown mechanisms in patients with chronic HCV infection. The assessments of core aa 70 substitution and polymorphisms near the IFNL3 gene could offer promising steps to improve the management of patients with HCV. PMID:27630727

Objective: The crucial role of angiogenesis in the pathophysiology of acute myeloid leukemia (AML) has been proposed. One of the key regulators of angiogenesis is the vascular endothelial growth factor (VEGF). Among the VEGF family, it has been observed that VEGF-A and VEGF-C are expressed by AML cells and mediate leukemic cell proliferation, survival, and resistance to chemotherapy. Emerging evidence, however, suggests that elevated levels of VEGF or a proangiogenic phenotype may impede, rather than promote, early tumor development and progression. As the significance of VEGF-A and VEGF-C levels in the pathogenesis of AML has not been clarified well, the aim of this study is to evaluate gene expression of these angiogenesis promoters and its possible prognostic value in peripheral blood mononuclear cells of Iranian patients with AML. Materials and Methods: We investigated the mRNA expression of VEGF-A and VEGF-C in peripheral blood mononuclear cells of 27 patients with newly diagnosed AML and 28 healthy controls by quantitative real-time PCR. Results: Expression of VEGF-C mRNA was significantly lower in AML patients than in healthy controls (p<0.001). However, there was no significant decrement in expression of VEGF-A mRNA of AML patients compared to the control group (p=0.861). VEGF-A and VEGF-C expression were not able to predict clinical outcome. Conclusion: Our data showed that AML is associated with a decreased expression of VEGF-C mRNA. However, expression levels did not influence the clinical outcome in our study. It seems that angiogenesis is affected by different cytokines other than VEGF-C or VEGF-A, and VEGF is also affected by different cytokines. Taken together, these findings help to provide new insights into the investigation of other angiogenic factors and cytokines that may play roles in the pathogenesis of AML. Conflict of interest:None declared. PMID:24385776
Breast cancer is the most common cancer in women worldwide. Doxorubicin-based chemotherapy is used to treat breast cancer patients; however, neutropenia is a common hematologic side effect and can be life-threatening. The ABCB1 and SLC22A16 genes encode proteins that are essential for doxorubicin transport. In this study, we explored the effect of 2 common polymorphisms in ABCB1 (rs10276036 C/T) and SLC22A16 (rs12210538 A/G) on the development of grade 3/4 febrile neutropenia in Iranian breast cancer patients. Our results showed no significant association between these polymorphisms and grade 3/4 febrile neutropenia; however, allele C of ABCB1 (rs10276036 C/T) (p = 0.315, OR = 1.500, 95% CI = 0.679–3.312) and allele A of SLC22A16 (rs12210538 A/G) (p = 0.110, OR = 2.984, 95% CI = 0.743–11.988) tended to have a greater association with grade 3/4 febrile neutropenia, whereas allele T of ABCB1 (rs10276036) (p = 0.130, OR = 0.515, 95% CI = 0.217–1.223) and allele G of SLC22A16 (rs12210538) (p = 0.548, OR = 0.786, 95% CI = 0.358–1.726) tended to protect against this condition. In addition to breast cancer, a statistically significant association was also observed between the development of grade 3/4 febrile neutropenia and other clinical manifestations such as stage IIIC cancer (p = 0.037) and other diseases (p = 0.026). Our results indicate that evaluation of the risk of grade 3/4 neutropenia development and consideration of molecular and clinical findings may be of value when screening for high-risk breast cancer patients.

Iranians express dysphoria through an undifferentiated term called narahati, meaning depressed, ill at ease, nervous, inconvenienced, or anxious. People try masking this emotion or express it in specific ways nonverbally, such as sulking or not eating. Two other dysphoric affects, sadness and anger, are not masked. Because of the social conception of persons being emotionally sensitive, the expression of narahati is guarded: expressing it not only could show that one is socially vulnerable, it could also make another sensitive empathic person narahat. The body is also sensitive, but to the physical world. Physical health is maintained by balancing a diet of "hot" and "cold" foods and avoiding exposure to cold and moisture. With the social and cultural problems brought on by revolution, war, immigration, and accommodation to a new society, Iranian refugees experience changes in family, role, status, finances, language, and other sociocultural ways of being that cause them to feel narahat and to express it verbally, nonverbally, or through somatization. Understanding Iranian conceptions of emotional and physical sensitivity will help clinicians in treating Iranian patients. PMID:1413773

BACKGROUND Irritable bowel syndrome (IBS) is a digestive system disorder with an unknown etiology. Serotonin has a key role in the secretion and motility of the intestine. Polymorphism in serotonin re-uptake transporter (SERT or SLC6A4) gene may have a functional role in the gut of patients with IBS. The aims of the present study were to investigate the association between SLC6A4 gene polymorphism and IBS and to detect the correlation between rectal serotonin levels and IBS sub-types. METHODS SLC6A4 gene polymorphism in 131 patients with IBS and 211 healthy controls were analysed using the quantitative polymerase chain reaction high-resolution melting (qPCR-HRM) curve technique. Serotonin was measured in rectal biopsies of patients with IBS using the enzyme-linked immunosorbent assay (ELISA) method. RESULTS The patients were categorized into three groups: IBS with diarrhoea (IBS-D): 70 patients, IBS with constipation (IBS-C): 18 patients, and IBS with mixed symptoms (IBS-M): 43 patients. The frequency of SLC6A4 s/s and l/s genotypes was significantly higher in IBS-C than IBS-D, IBS-M, and controls (p=0.036). Serotonin levels were similar in IBS sub-types. CONCLUSION SLC6A4 polymorphism is a possible candidate gene associated with the pathogenesis of IBS-C. Although serotonin levels did not differ in rectal biopsies of IBS sub-types, further investigation is recommended.

Type 1 diabetes mellitus is frequently associated with autoimmune thyroid disease (ATD).Genetic susceptibility for autoantibody formation in association with ATD and type 1 diabetes mellitus has been described with varying frequencies, but there is still debate about its prevailing situation in Iran. We have therefore investigated the prevalence of anti-thyroid peroxidase (anti-TPO) and anti thyroglubolin (Anti TG) antibodies in type 1 diabetic patients, and compared the effect of age and sex on the thyroid autoimmunity in patients with type 1 diabetes mellitus in Iran.Ninety one subjects with type 1 diabetes mellitus and one hundred and sixty three unrelated normal controls under the age of thirty years were recruited for the detection of anti-TPO and anti-TG. Radio Immuno Assay and chemiluminescence methods were used for anti-TPO and anti-TG detection respectively.Among 91 type 1 diabetic patients, 36 (39.6%) were positive for anti-TPO and 27(30%) were positive for antiTG. Anti-TPO antibodies were detected only in 6.7% of control group. Comparing with those without thyroid autoimmunity, there was a female preponderance for the type 1 diabetic patients with thyroid autoimmunity (female: male, 28:14 vs. 28:20 respectively). Among the type 1 diabetic patients those with thyroid autoimmunity, tended to be older (p: 0.04) and to have higher TSH concentration (p: 0.03). Patients with high anti-TPO levels had longer duration of diabetes (P: 0.02).The presence of anti-TPO in 39.6% of our type 1 diabetic patients comparing with 8.5% of normal subjects confirmed the strong association of ATD and type 1 diabetes mellitus.
Purpose This study aimed to compare the effects between group discussion and educational booklet on nursing students’ attitude and practice toward patient privacy in Iran. Methods A two-group, pre-test and post-test design study was conducted in 2015. The study was conducted on 60 nursing students in Kashan, Iran who were randomly allocated into two groups to be trained on patient privacy either through group discussion or by an educational booklet. The students’ attitude and practice was assessed before and after the education using a questionnaire and a checklist. Data analysis was performed through paired t-test, Wilcoxon signed ranks test, and independent samples t-tests. Results Before the intervention, no significant difference was found between the group designated to group discussion and that designated to the educational booklet in the mean overall score of attitude (P=0.303) and practice (P=0.493) toward patient privacy. After the intervention, the mean attitude score significantly increased in the two groups (P=0.001). Moreover, the students’ practice score increased in the discussion group while it did not significantly change in the booklet group (P=0.001). Conclusion Both methods were effective on the students’ attitude; however, the educational booklet did not affect their practice toward patient privacy. Group discussion can effectively improve the students’ attitude and practice toward patient privacy. PMID:27476641

Introduction Ataxia telangiectasia (AT) is a rare human neurodegenerative autosomal recessive multisystem disease. AT is the result of mutations in the AT-mutated (ATM) gene. ATM protein is required for radiation-induced apoptosis and acts before mitochondrial collapse. The tRNA genes are considered one of the hot spots for mutations causing mitochondrial disorders. Due to the important role of ATM in apoptosis and its effect on the cell cycle it might be possible that it has a central role in mtDNA mutations. On the other hand, the tRNALys/Leu gene and also ATPase6 and ATPase8 genes are important for many mitochondrial diseases and many causative mutations have been reported from these genes. Material and methods In the present research, we performed mutation screening for these genes in 20 patients who were diagnosed with ataxia telangiectasia by a PCR sequencing method. Results The results showed a significant level of mtDNA variations in AT patients. Among 20 patients in this study, 12 patients (60%) were detected with point mutations, among which 8 mutations (40%) belonged to the MT-ATP6 gene. There was probably a second effect of mtDNA mutations in AT disease and mtDNA plays a main role in establishment of AT. Conclusions MtDNA mutations might be responsible for the decline of mitochondrial function in AT patients. Mitochondrial investigation can help to understand the mechanism of damage in AT disease.

Women in the world have made great contributions to science. In Iran more than 60% of undergraduate university students are women, most in physics. Women's representation in postgraduate studies is lower; however, these numbers do not account for those who go to other countries to continue their studies, of which there are many. Alinoush Tarian, the oldest woman professor in Iran, the first Iranian woman professor of physics, and the founder of the first solar telescopic observatory in Iran, is one of them. There are some women physicists in Iran that are working as professors at the universities and famous institutes such as the Institute for Studies in Theoretical Physics and Mathematics. Iranians have always showed their talents and intelligence everywhere in the world, and nowadays, some of the women physics teachers in Iran are trying to teach physics with new methods to attract more students.

Adiponectin, an adipose-derived plasma protein, is reduced in patients with obesity and type 2 diabetes. Thiazolidinediones can increase adiponectin levels and improve insulin sensitivity. This study investigated the associations between type 2 diabetes and two single-nucleotide polymorphisms in the adiponectin (45T/G) and adiponectin receptor-2 gene (795G/A), and investigated whether these genetic variants affect the response to pioglitazone in Iranian patients with type 2 diabetes. We genotyped 128 non-diabetic participants and 101 patients with type 2 diabetes for 45T/G and 795G/A with polymerase chain reaction-restriction fragment length polymorphism assays. Patients were treated with pioglitazone for 12 weeks, after which we compared laboratory parameters in these two groups. Fasting blood sugar differed significantly in individuals with different 795G/A genotypes after pioglitazone treatment (P = 0.009). The mean decrease in insulin/glucose ratio after treatment also differed significantly in individuals with different 45T/G genotypes (P = 0.035). The T allele frequency for 45T/G was 87.11% in controls versus 81.68% in patients (P = 0.071). The TG and GG genotypes were more frequent in patients (P = 0.032). The G allele frequency for 795G/A was 76.17% in controls versus 80.20% in patients (P = 0.179). 795G/A variants were not significantly different between patient and control group. The adiponectin gene 45T/G mutation may be an important determinant of type 2 diabetes in the Iranian population. However, adiponectin 45T/G and adiponectin receptor-2 795G/A polymorphisms were not significantly associated with the response to pioglitazone in our sample.

Objective. To investigate the safety and efficacy of MLC601 (NeuroAid) as a traditional Chinese medicine on motor recovery after ischemic stroke. Methods. This study was a double-blind, placebo-controlled clinical trial on 150 patients with a recent (less than 3 month) ischemic stroke. All patients were given either MLC601 (100 patients) or placebo (50 patients), 4 capsules 3 times a day, as an add-on to standard stroke treatment for 3 months. Results. Sex, age, elapsed time from stroke onset, and risk factors in the treatment group were not significantly different from placebo group at baseline (P > .05). Repeated measures analysis showed that Fugl-Meyer assessment was significantly higher in the treatment group during 12 weeks after stroke (P < .001). Good tolerability to treatment was shown, and adverse events were mild and transient. Conclusion. MLC601 showed better motor recovery than placebo and was safe on top of standard ischemic stroke medications especially in the severe and moderate cases. PMID:21776364

The aim of this study was to evaluate mixed red cells population and red blood cell chimerism after hematopoietic stem cell transplantation. Red blood cell chimerism after hematopoietic stem cell transplantation was analyzed using a series of fluorescein isothiocyanate-conjugated monoclonal antibodies (BioAtlantic, France) directed against ABH, Rh (D, C, E, c, e), Kell, Duffy, Kidd, and Ss antigens on blood samples of 14 patients with hematologic disorders undergoing hematopoietic stem cell transplantation, by flow cytometric method on days 15, 30, and 60 after transplantation. All patients showed expression of donor red cell antigens within days 15 - 30 after hematopoietic stem cell transplantation. Graft versus host disease and ABO incompatibility did not affect the expression of chimerism. Flow cytometric analysis is a simple, accurate, and valuable test which is of significant help in monitoring chimerism in allogeneic hematopoietic stem cell transplantation.

The ABO blood group has been recently proposed to influence development of oral cancer. The aim of this study was to evaluate the association between the type of ABO blood group and oral cancer. In a case-control study, 104 patients with oral cancer were compared with 90 blood donors without cancer as controls. Data regarding the patient demographics, blood groups, Rh status, cancer characteristics and oral habits were also compared between two subgroups of squamous and non-squamous oral cancers. For statistical analysis, Chi-square test, t-student Test and Logistic Regression were used to analyze the relationship between ABO blood groups and oral cancer. The frequency of blood group B was significantly higher in oral cancer patients than controls (32% vs 13%) (p value=0.01), but Rh factor did not show significant difference between cases and controls. According to Logistic Regression, people with blood group B and those older than 50 had 3.5 and 19.4 times elevated risk of developing oral cancer, respectively. The frequency of squamous cell cancer was also significantly higher in men and people older than 50. On the other hand, females, people under 50, and those with blood group B were at 5.6, 2.9 and 4.3 times higher risk of developing non-squamous cell oral cancer,respectively. People with blood group B are at a greater risk of developing oral cancer, and female patients under 50 years of age with blood group B have the highest risk to develop non-squamous cell oral cancer.
Organ shortage for transplantation remains a worldwide serious problem for kidney patients with end-stage renal failure, and several countries have tried different models to address this issue. Iran has 20 years of experience with one such model that involves the active role of the government and charity foundations. Patients with a desperate demand for a kidney have given rise to a black market of brokers and other forms of organ commercialism only accessible to those with sufficient financial resources. The current Iranian model has enabled most of the Iranian kidney transplant candidates, irrespective of socioeconomic class, to have access to kidney transplantation. The Iranian government has committed a large budget through funding hospital and staff at the Ministry of Health and Medical Education by supporting the brain death donation (BDD) program or redirecting part of the budget of living unrelated renal donation (LURD) to the BDD program. It has been shown that it did not prevent the development and progression of a BDD program. However, the LURD program is characterized by several controversial procedures (e.g., confrontation of donor and recipient at the end of the evaluation procedure along with some financial interactions) that should be ethically reviewed. Operational weaknesses such as the lack of a registration system and long-term follow-up of the donors are identified as the 'Achilles heel of the model'.

Aim. To evaluate maternal TNF-alpha and IL-6 plasma levels in normotensive pregnant women, women with preeclampsia, and to examine the temporal changes in their levels from theantepartum to the postpartum period correlated with the regression of preeclampsia. Method. A prospective study was performed in the 2nd Department of Obstetrics and Gynecology, University of Athens. Blood samples were obtained: (1) antepartum at the time of clinical diagnosis of the syndrome, 2. 12-14 weeks postpartum. Results. No statistically significant differences were found in IL-6 levels, whereas a difference was found in TNF-alpha levels between preeclamptic and controls in antepartum period (0.80 pg/ml versus 0.60 pg/ml, P : .04). Long after delivery, TNF-alpha levels were significantly higher in preeclamptic compared to normotensive controls (0.86 pg/ml versus 0.60 pg/ml, P : .004). No difference was observed in TNF-alpha before and after delivery in both groups. No difference was noticed in IL-6 levels in women of normotensive group long after delivery compared to that before delivery. Long after delivery IL-6 levels were statistically significant higher in preeclamptic women compared to normal controls (3.53 ± 0.52 pg/ml versus 1.69 ± 0.48 pg/ml, P : .02). Conclusion. Preeclamptic women remain under a status of increased inflammatory stress up to 12-14 weeks postpartum despite the fact that all the other signs of preeclampsia are resolved. PMID:21253506

Background: Progressive encephalopathy with or without lipodystrophy is a rare autosomal recessive childhood-onset seipin-associated neurodegenerative syndrome, leading to developmental regression of motor and cognitive skills. In this study, we introduce a patient with developmental regression and autism. The causative mutation was found by exome sequencing. Methods: The proband showed a generalized hypertonia and regression of all developmental milestones. Based on the advantages of next-generation sequencing (NGS), whole exome sequencing (WES) was requested. The functional significance of variants was evaluated by NGS-specific prediction servers. Sanger sequencing was used for segregation analysis in the family. Results: There was no specific sign in the clinical and paraclinical investigations of the patient to establish a conclusive clinical diagnosis. WES detected a known homozygous nonsense mutation in BSCL2 (NM_001122955.3:c. 985C>T; p.Arg329*). The variant is segregating in the pedigree with an autosomal recessive pattern. Conclusion: Exome sequencing is a robust method for identifying the candidate gene variants in Mendelian traits. PMID:27452399

Introduction Preeclampsia is a disorder of pregnancy, characterized by hypertension and proteinuria after 20 weeks of gestation. Here, we evaluated the role of aspirin triggered-lipoxin A4 (ATL, 15-epi-LXA4) on the modulation of the adhesion of human polymorphonuclear neutrophils (PMN) to endothelial cells initiated by preeclamptic plasma. Materials and methods Plasma from preeclamptic, normotensive pregnant, and non-pregnant women were analysed for factors involved in regulating angiogenesis, inflammation and lipid peroxidation. Plasma from preeclamptic women was added to human umbilical vein endothelial cells, and the adhesion of PMN (incubated with or without ATL) to cells was evaluated. Results Preeclampsia was associated with some augmented anti-angiogenic, oxidative and pro-inflammatory markers, as well as increasing human PMN-endothelial cell adhesion. This cell adhesion was reduced when human PMN were incubated with ATL prior to addition to endothelial monolayers. Discussions and Conclusions Our results are the starting point for further research on the efficacy and rational use of aspirin in preeclampsia. PMID:22974760

Low plasma level of vitamin D is linked to the increased risk of cardiovascular diseases such as hypertension, diabetes, dyslipidemia and peripheral vascular diseases. Vitamin D deficiency is a worldwide problem that involves Iranian population. To the best of our knowledge, this was the first investigation on venous thromboembolism (VTE) subjects that assessed the correlation of vitamin D level with plasma P-selectin, hs-CRP, and risk factors of thrombosis. In this prospective pilot study, patients with diagnosis of acute deep vein thrombosis and/ or pulmonary embolism were enrolled. All patients' clinical data, demographics and risk factors of thrombosis were evaluated. Plasma level of P-selectin and hs-CRP were measured by ELISA method. Radio immune assay method was used to determine plasma level of 25-hydroxy vitamin D (25(OH) D). In this study, 60 subjects were included. The mean ± SD plasma 25-hydroxy vitamin D level (25(OH) D) of participants was 21.4 ± 14.6 ng/mL. The vitamin D deficiency was detected in 60% of patients. No significant relation was found between the plasma 25(OH)D level and P-selectin and hs-CRP. In multiple regression analysis, there was a significant relationship between the level of 25(OH)D and the patients' age (beta = 0.452; p = 0.001), diabetes (beta = 0.280; p = 0.036) and positive family history of cardiovascular diseases (beta = 0.373; p = 0.003). Vitamin D deficiency is a frequent problem in Iranian VTE patients. Moreover, Plasma level of vitamin D is not associated with P-selectin and hs-CRP in VTE patients.

Background: Fundamental problems with Personality Disorders (PD) diagnostic system in the previous version of DSM, led to the revision of DSM. Therefore, a multidimensional system has been proposed for diagnosis of personality disorder features in DSM-5. In the dimensional approach of DSM-5, personality disorders diagnosis is based on levels of personality functioning (Criteria A) and personality trait domains (Criteria B). Objectives: The purpose of this study was firstly, to examine the DSM-5 levels of personality functioning in antisocial and borderline personality disorders, and second, to explore which levels of personality functioning in patients with antisocial and borderline personality disorders can better predicted severity than others. Patients and Methods: This study had a cross sectional design. The participants consisted of 252 individuals with antisocial (n = 122) and borderline personality disorders (n = 130). They were recruited from Tehran prisoners, and clinical psychology and psychiatry centers of Razi and Taleghani Hospitals, Tehran, Iran. The sample was selected based on judgmental sampling. The SCID-II-PQ, SCID-II and DSM-5 levels of personality functioning were used to diagnose and assess personality disorders. The data were analyzed by correlation and multiple regression analysis. All statistical analyses were performed using the SPSS 16 software. Results: Firstly, it was found that DSM-5 levels of personality functioning have a strong correlation with antisocial and borderline personality symptoms, specially intimacy and self-directedness (P < 0.001). Secondly, the findings showed that identity, intimacy and self-directedness significantly predicted antisocial personality disorder severity (P < 0.0001). The results showed that intimacy and empathy were good predictors of borderline personality disorder severity, as well (P < 0.0001). Conclusions: Overall, our findings showed that levels of personality functioning are a significant

Background: The main objective of nursing is to provide comprehensive nursing care that is appropriate to patients’ needs. However, the incidence of missed nursing care compromises the provision of comprehensive and safe care and threatens patients’ lives. Thus, this in-depth qualitative study aimed to explore nurses’ experiences of missed care and factors affecting it. The aim of this study was to describe nurses’ experiences of missed care in clinical practice. Methods: In this study, qualitative research methodology, with a content analysis approach was used. The sample included 23 nurses in referral teaching hospitals. Data were collected through focus group discussions, face-to-face and telephonic interviews, using semi-structured questions. Results: Three themes, comprising several sub-themes, emerged, and included contextual conditions, coercion, and deprivation. Conclusion: The results indicated that organizational and personal factors facilitate the incidence of coerced, missed nursing care. High quality of care, the prevention of missed care incidences and patient safety depend on the provision of adequate staff, appropriate equipment and a sense of responsibility for patients’ care needs among nurses.

Iran in recent decade faced several regional and international sanctions in foreign trade, financial and banking services. Iran national pharmaceutical industry has always played a major role in providing medicines to the Iranian patients. However, following the sanctions it has faced profound difficulties for importing of both finished products and pharmaceutical raw materials. Although medicines are exempted from sanctions, due to restriction on money transaction and proper insurance Iranian pharmaceutical companies have to pay cash in advance for imports of medicines and raw materials or to secure offshore funds at very high risks. Current situation in Iran pharmaceutical market confirms that the sanctions against Iran are affecting ordinary citizens and national health sector which resulted to reduction of availability of lifesaving medicines in the local market and has caused increasing pain and suffering for Iranian patients.

Iran is suffering from the 2nd most severe addiction to opioids in the world. While the explanation of this enormous drug problem is refutably related to drug trafficking, the drug dilemma also illustrates the chain reaction of the imposed war with Iraq in 1980 - 88; the problems of poverty, unemployment, urbanization, homelessness, adultery, family crises, divorce, domestic violence, and runaway children. Although opium addiction often linked to these factors, drug use is common among all social classes. It seems that a positive traditional attitude is another reason for widespread raw opium use in this country. A survey in Iranian literature reveals that famous Iranian poets, who have a substantial contribution on cultural attitude formation of Iranian population, have used the phrase “Teriac” (raw opium) as a means of “antidote” a substance that treats every disease. It seems that a concrete deduction from the literature has been leaden to a positive attitude towards opium consumption in Persian culture. Recent research also supports this idea. Many patients use raw opium as a pain killer or for treating hyperlipidemia, hypertension, diabetes and other chronic diseases; most of them had started the use after developing the disease and the remaining had increased the consumption after developing the disease. Regarding this superstitious common belief, drug control headquarters should focus on education and correction of the faulty unhealthy attitude toward opium consumption. PMID:26288642

Abstract Preeclampsia (PE) is characterized by maternal hypertension, proteinuria, oedema and, in 30% of cases, by intrauterine growth retardation. Causes are still unknown; however, epidemiological and clinical studies have suggested alterations in maternal calcium metabolism. We suggested that in PE, calcium transport by the syncytiotrophoblast (ST) is disturbed. From total placental tissues, we studied the expression of: calcium channels (TRPV5, TRPV6 [transient receptor potential vanilloid]), calcium binding proteins (CaBP-9K, CaBP-28K), plasma membrane calcium ATPase (PMCA)1,2,3,4 pumps, ATP synthase, genes implicated in Ca2+ release [inositol-1,4,5-triphosphate receptor (IP3R)1,2,3; Ryanodine receptor (RyR)1,2,3] and replenishment (SERCA1,2,3 [sarcoendoplasmic reticulum Ca2+ ATPases]) from endoplasmic reticulum, channels implicated in mitochondrial Ca2+ accumulation (VDAC1,2,3 [voltage-dependent anion channels]) and a marker of oxidative stress (hOGG1 [Human 8-oxoguanine-DNA glycosylase 1]), as well as the influence of these variations on calcium transport in primary ST cultures. The mRNA and protein levels were thereby examined by real-time PCR and Western blot analysis, respectively, in two different groups of pregnant women with similar gestational age: a normal group (n= 16) and a PE group (n= 8), diagnosed by a clinician. Our study showed a significant decrease in calcium transport by the ST cultured from preeclamptic placentas. We found a significant (P < 0.05) decrease in mRNA levels of TRPV5, TRPV6, CaBP-9K, CaBP-28K, PMCA1, PMCA4, ATP synthase, IP3R1, IP3R2, RyR1, RyR2 and RyR3 in PE group compared to normal one. We also noted a significant decrease in protein levels of TRPV5, TRPV6, CaBP-9K, CaBP-28K and PMCA1/4 in PE group. In contrast, SERCA1, SERCA2, SERCA3, VDAC3 and hOGG1 mRNA expressions were significantly increased in PE placentas. Calcium homeostasis and transport through placenta is compromised in preeclamptic pregnancies and it appears to

Background Mutations in STOX1 were proposed to be causal for predisposing to preeclampsia, a hypertensive disorder originating from placental defects, affecting up to 10% of human pregnancies. However, after the first study published in 2005 three other groups have dismissed the polymorphism described in the first paper as a causal mutation. Methodology and Principal Findings In the present study, we have produced a choriocarcinoma cell line overexpressing STOX1. This overexpression results in transcriptional modification of 12.5% of the genes, some of them being direct targets as shown by chromatin immunoprecipitation. STOX1 overexpression correlates strongly and specifically with transcriptomic alterations in preeclamptic placentas (r = 0.30, p = 9.10−7). Numerous known key modulators of preeclampsia (such as Endoglin, Syncytin, human chorionic gonadotrophin -hCG-, and Glial Cell Missing Homolog -GCM1-) were modified in these transformed choriocarcinoma cells. Conclusions Our results contribute to reconcile contradictory data concerning the involvement of STOX1 in preeclampsia. In addition, they strongly suggest that anomalies in STOX1 expression are associated with the onset of preeclampsia, thus indicating that this gene should be the target of future studies. Our cellular model could constitute an invaluable resource for studying specific aspects of this human disease. PMID:19079545

Calpain3 is a calcium-dependent intracellular protease involved in an autosomal recessive form of muscular dystrophy known as limb-girdle muscular dystrophy type 2A. Many pathogenic mutations have been identified in calpain3, encoded by the CAPN3 gene, which leads to weakness of the pelvic and shoulder girdle muscles. In the present study, whole exome sequencing was performed on six unrelated Iranian families who presented with progressive muscle weakness, with a strong suspicion of Calpainopathies. Genetic analysis of CAPN3 gene revealed five causative variants which had not been reported in the Iranian population before including a novel 6 bp deletion (c.795_800delCATTGA) and four previously reported mutations (c.1939G > T, c.2243G > A, c.2257delGinsAA, and c.2380 + 2T > G). Our findings indicate that exome sequencing can be a very effective and affordable method to diagnose heterogeneous muscular dystrophies, especially in consanguineous populations such as Iran.

Root cause analysis (RCA) has been widely used for retrospective investigations of patient safety incidents. To increase patient safety competencies, RCA has recently been introduced in Iranian hospitals. The aims of the current study were to explore team members' experiences and perceptions of RCA and to identify the challenges and benefits of using it in Iranian hospitals from their perspective. A qualitative study was conducted consisting of 32 semi-structured interviews with health professionals who participated in the national training programme and were involved in RCA investigations. Data were analysed using the thematic analysis method. The participants encountered a range of obstacles while conducting RCA, including time constraints, a lack of resources, the blame culture and unsupportive colleagues. They stressed the need for further leadership support and cultural change within the Iranian healthcare system to facilitate the application of RCA. RCA was perceived as a beneficial analytical tool that improved patient care, fostered teamwork and communication among staff and promoted safety culture. This study concluded that applying RCA in the Iranian healthcare setting has had a significant impact on improving commitment to safety. However, the general adoption of this method is hindered by the lack of workplace and system supports. To maximize profits from RCA, clinical leaders must assign a high priority to RCA investigations and support RCA team efforts. Copyright © 2016 John Wiley & Sons, Ltd.

The aim of this investigation was to determine the expression of fatty acid binding protein 4 (FABP4) in the placenta from women with preeclampsia and normal pregnancy, and to delineate the regulatory effects on thophoblast cell by FABP4. We determined the expression of FABP4 by real-time polymerase chain reaction (PCR) for messenger ribonucleic acid (mRNA) or enzyme-linked immunesorbent assay (ELISA) and Western blotting for protein. Small interference of ribonucleic acid (siRNA) and specific FABP4 inhibitor were used to inhibit FABP4. The proliferation, migration and invasion of trophoblastic cells (Swan-71 and Jar) were evaluated with cell counting kit-8, wound-healing test and transwell analysis respectively. We found the expression of FABP4 was significantly higher in the placenta of preeclamptic women than that of women with normal pregnancy (t = 4.244, P < 0.001 for mRNA; t = 4.536, P < 0.001 for protein). FABP4 siRNA significantly reduced the proliferation of trophoblasts (P < 0.001). The specific inhibition of FABP4 inhibited the proliferation of trophoblasts in a dose-dependent manner (P < 0.001) and the inhibitory effect increased as the concentration of inhibitor increased. FABP4 siRNA and specific inhibitor significantly decreased the migration (P < 0.001) and invasion (P < 0.001) of trophoblasts. We concluded the increase in placental FABP4 expression in preeclampsia may affect the function of trophoblast, and this increase may have a role in the pathogenesis of preeclampsia.

Preeclampsia is a potentially fatal pregnancy disorder affecting millions of women around the globe. Dysregulation in gene and protein expression within key biological pathways controlling angiogenesis has been implicated in the development of preeclampsia. Altered CpG methylation, a type of epimutation, may underlie this pathway dysregulation. In the present study, placental tissue from preeclamptic cases and normotensive controls was analyzed for genome-wide differential CpG methylation and concomitant changes in gene expression. A set of 123 genes, representing 19.9% of all genes with altered CpG methylation, was associated with functional changes in transcript levels. Underscoring the complex relationships between CpG methylation and gene expression, here hypermethylation was never associated with gene silencing, nor was hypomethylation always associated with gene activation. Moreover, the genomic region of the CpG mark was important in predicting the relationship between CpG methylation and gene expression. The 123 genes were enriched for their involvement in the transforming growth factor beta (TGF-β) signaling pathway, a known regulator of placental trophoblast invasion and migration. This is the first study to identify CpG hypomethylation as an activator of TGF-β-associated gene expression in the preeclamptic placenta. The results suggest functional epimutations are associated with preeclampsia disease status and the identified genes may represent novel biomarkers of disease. PMID:26510177

Recent large use of magnesium in the obstetric population should incite anesthesiologists to control its side effects and drugs interactions. We report a case of a 30-year-old woman, with severe preeclampsia and HELLP syndrome, receiving sulfate magnesium and nicardipine, who underwent a cesarean section under general anesthesia. She developed a prolonged and deep neuromuscular blockade, which was antagonized three hours later with neostigmine. In case of therapeutic hypermagnesaemia, non-depolarizing relaxants must be used in reduced doses, and at increased time intervals, with appropriate neuromuscular monitoring. PMID:28154698

There is diversity in clinical outcome of Helicobacter pylori infection in different regions. Microbial, host and environmental factors seem to be reason of such variation. Considering microbial factors, we studied H. pylori genotypes and their association with clinical feature of the infection. Overall 160 H. pylori-positive patients were enrolled in this study. Clinical information and biopsy were collected from each patient. The presence of the major virulence genes were determined by PCR. Regardless to clinical outcomes, vacA, cagA, cagE, oipA, iceA1, babA2 and babB genes was positive in 100%, 69%, 51%, 55%, 26%,78% and 28% of 160 strains respectively. The s1m2 was more common vacA allels and s1a and m1a were predominant s and m regions. In patient with gastric cancer (GC), the oipA was less frequent while the iceA1 was the most common. The babA2 was common in all patient groups. The babB was significantly observed in strains isolated from patients with GC. There were significant association among cagA status with presence of vacAs1, vacAm2, cagE, oipA, iceA1 and babA2. Presence of the babB and oipA was connected with higher and lower risk for GC respectively. There was no association between the cagA, vacA, cagE or iceA status and clinical outcome in patients in Iran. We showed that presence of the babB and iceA1 were significantly connected with higher risk for gastric cancer development in Iranian dyspeptic patients while H. pylori isolates with positive oipA had little threat for leading patients to cancer.

Background: Myeloproliferative neoplasms (MPNs) are clonal malignant diseases that represent a group of conditions including polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF). The aim of this study was to evaluate possible correlations between JAK2V617F allele burden and clinicohematologic characteristics in Iranian patients with MPNs. We also aimed at determining the correlation between JAK2V617F allele burden and use of cyto reductive treatment (hydroxyurea). Materials and Methods: We performed ARMS-PCR for all MPNs samples and subsequently performed real-time quantitative polymerase chain reaction (qRT-PCR) for JAK2V617F allele burden measurement using DNA from peripheral blood leukocytes. Results: Two distinct groups of patients were examined at a single time point: group A (n=40; 20 PV, 20 ET) was examined at the time of diagnosis; group B (n=85; 40 PV, 30 ET and 15 PMF) while under treatment with hydroxyurea (HU). The median allele burden of the JAK2 V617F was 72% for PV and 49% for ET patients at the time of diagnosis (p=0.01). For patients with HU treatment, we determined the median JAK2V617F allele burden to be 43%, 40%, and 46.5 % in PV, ET and PMF patients; respectively. HU-treated PV patients had a significant lower %JAK2V617F than PV patients at the time of diagnosis (43% vs. 72%, p=0.005). In ET group, the relationship between the JAK2 V617F allele burden and leukocyte count was significant (p=0.02 and p=0.01 in untreated and treated patients, respectively). Conclusions: Our results showed that patients with PV have a higher JAK2V617F allele burden. Moreover, our study demonstrated that the JAK2V617F allele burden correlates with clinical features in ET group. We also showed hydroxyurea can affect the JAK2V617F allele burden in PV patients.

To examine the moderating role of spirituality between hopelessness, spirituality, and suicidal ideation, 202 Iranian depressed adolescent inpatients completed measures of patient health, suicidal ideation, hopelessness, and core spiritual experience. Structural equation modelling indicated that depressed inpatients high in hopelessness, but also high in spirituality, had less suicidal ideation than others. These findings reinforce the importance of spirituality as a protective factor against hopelessness and suicidal ideation.

Background The incidence of oral cancers varies from one country to another, which can be clarified by the difference in the distribution of the risk factors and the possible etiologies. Tongue is a main segment of oral cavity and malignant lesions of this region accounts for nearly 30% of all oral cancers. Objectives In the present study, we evaluated the pattern of tongue cancer in Iranian population and compared these findings with those previously reported in the other countries. Methods In this multicenter, retrospective cross-sectional study recorded cases of the malignant tongue tumors in the cancer research center (CRC) of Shahid Beheshti University of Medical Sciences were extracted. The patient records and their microscopic reports were retrieved from the archives and age, sex and microscopic types were evaluated. It is to be noted that the CRC has been serving as a cancer registry center for major hospitals all over the country since the year of 2003. Thus, the obtained statistics are highly reliable. Results During the years 2003 to 2008, a total number of 952 new cases of the tongue cancer were recorded in the CRC. Most cases are diagnosed in the sixth and seventh decades of life. 450 cases (47.2%) occurred in men and 489 cases (51.36%) in women. Four different types of malignant lesions (epithelial, salivary gland, hematopoietic and mesenchymal) were diagnosed. Epithelial tumors were the most prevalent malignancies (93%) of which squamous cell carcinoma (SCC) made up 87.39% of all lesions. Salivary gland tumors had the second place with 3.15% of the total lesions. Conclusions In Iranian population, squamous cell carcinoma is the most prevalent malignancy of tongue and it is notable that the ratio of female to male population was equal. These lesions were prevalent in the sixth and seventh decades of life. Thus screening examination of tongue by dentist especially in elderly patients is necessary for early detection of cancerous lesions. PMID:27761209
Background During preeclampsia, placental angiogenesis is impaired. Factors released from the placenta including vascular endothelial growth factor (VEGF), placental growth factor (PLGF), soluble VEGF receptor 1 (sFlt1), and soluble endoglin (sEng) are regulatory molecules of placental development and function. While the renin angiotensin system has been shown to regulate angiogenic factors in other research fields, these mechanisms have not been extensively studied during pregnancy. Methods We evaluated the effects of angiotensin II (Ang II) and angiotensin-(1-7) [Ang-(1-7)] on the release of VEGF, PLGF, sFlt1, and sEng from placental chorionic villi (CV). CV were collected from nulliparous third-trimester normotensive and preeclamptic subjects. CV were incubated for 0, 2, 4, and 16 hours with or without Ang II (1 nM and 1 microM) or Ang-(1-7) (1 nM and 1 microM). The release of VEGF, PLGF, sFlt1, sEng, lactate dehydrogenase (LDH), and human placenta lactogen (HPL) was measured by ELISA. Results The release of sFlt1, PLGF, sEng from normal and preeclamptic CV increased over time. Release of sFlt1 and sEng was significantly higher from preeclamptic CV. VEGF was below the detectable level of the assay in normal and preeclamptic CV. After 2 hours, sFlt1 release from normal CV was significantly inhibited with Ang II (1 nM and 1 microM) and Ang-(1-7) (1 nM and 1 microM). There was a time-dependent increase in HPL indicating that the CV were functioning normally. Conclusions Our study demonstrates a critical inhibitory role of angiotensin peptides on sFlt1 in normal pregnancy. Loss of this regulation in preeclampsia may allow sFlt1 to increase resulting in anti-angiogenesis and end organ damage in the mother. PMID:21050477

Background It seems that there is a relationship between consanguinity and profound hearing loss but there is little data about the association of consanguinity and hearing loss in Iran. Objectives The aim of this study is to demonstrate the causes of profound bilateral sensorineural hearing loss among Iranian samples who are candidates for cochlear implantation. Methods This study was retrospective, analytical, and designed to collect information about profound hearing impaired cases referred to the Baqiyatallah Cochlear implantation center using enumeration. A total of 310 children with profound hearing impairments participated in this study. They were aged from 6 months to 4 years old. The study was done between January 2007 and April 2009. Chi-square tests were used to show whether there was any statistical difference between the incidence of marital consanguinity of their parents and the normal population. Results Sixty-five percent of those 310 children had parents who had married with their relatives. Of the 203 (65%) parents that had consanguineous marriages, 132 were first cousins, which includes the children of two brothers (37 [11.8%] patrilateral parallel cousins), the children of two sisters (38 [12.2%] multi-lateral parallel cousins), or the children of a brother and a sister (57 [18.3%] cross cousins). Fifty-four (17.4%) of the parents were second cousins and 17 (5.2%) were beyond second cousins. Also, hearing loss etiology was obvious in 237 (76.3%) of the patients with profound hearing loss but was unknown in 73 (23.7%). Hereditary was identified as the most common cause in 33% of the cases. Conclusions Our data demonstrated a 65% occurrence of consanguineous marriage among the parents of deaf children, which is statistically different from the percentage of consanguineous marriage among Iranian population (38%). This indicates an obvious relationship between severe hearing loss and consanguineous marriage. PMID:28191326

Menorrhagia is a common problem. Medical management for menorrhagia includes hormonal and nonhormonal treatments. These treatments have different side effects, which reduce quality of life. Complementary and traditional medicines have been used to handle menorrhagia for centuries in many cultures. There is a lot of information and data in Iranian traditional documents or books about medicinal herbs that are used by Iranian traditional medicine scientists for the treatment of menorrhagia. The aim of this study was to review the approaches to menorrhagia in Iranian traditional medicine texts. In this study, some main Iranian traditional medicine manuscripts including Canon of Medicine and Al-Havi of Rhazes were studied to extract important information about menorrhagia management. Iranian traditional medicine physicians have relied on an organized system of etiological theories and treatments for menorrhagia. Their methods for menorrhagia management may be able to convince the desire of many women to preserve their uterus and avoid hormonal therapy.

Background: Little is known about the features of Iranian nursing journals, specifically the subject areas used in articles, study designs, sampling methods, international collaboration of Iranian nursing scholars, specialty and academic rank of authors, and the most frequently contributing academic institutions in articles. Objectives: The aim of this study was to analyze the content of the articles published in Iranian scientific nursing journals. Materials and Methods: Quantitative content analysis was implemented to study Iranian nursing journals, which were approved by the commission for accreditation and improvement of Iranian medical journals in 2011. Thus, 763 articles from six journals, published from 2009 through 2011, were investigated. Data were extracted from the abstracts and when necessary, from the full-text of articles by visiting the websites of these journals. Descriptive statistics were used to analyze the data. Results: The main subjects of published articles in Iranian scientific nursing journals were consecutively renal dialysis (n = 21), intensive care unit (n = 16), nursing education (n = 15), patient satisfaction (n = 13), quality of life (n = 12), health education (n = 11), patient education (n = 11), pain (n = 10), and education (n = 9). The majority of authors had nursing and midwifery specialty (52.59%) followed by epidemiology/biostatistics specialty (7.72%). Isfahan, Tehran, Shahid Beheshti, Iran, Baqiyatallah, and Urmia universities of medical sciences had consecutively the largest number of publications in the studied journals. Only three papers (0.39%) were published by the international collaboration. Conclusions: Iranian nursing journals should publish special issues in the neglected subject areas. These journals should encourage authors to publish research evidence with higher quality. PMID:25741512

Background: One of the most important challenges of Iranian health care system is “quality of care,” and it is assumed that motivated nurses are more ready to provide better care. There are limited studies investigating Iranian nurses’ motivations; however, factors which motivate them have not been studied yet. Identifying the motivating factors enables nurse managers to inspire nurses for continuous quality improvement. The aim of this study was to identify motivating factors for Iranian hospital nurses. Materials and Methods: This is a cross-sectional descriptive study in which 310 nurses working at 14 hospitals of Tehran University of Medical Sciences were selected by proportionate stratified random sampling. Data were collected in 2010 by a researcher-developed questionnaire. Descriptive statistics and independent t-test, analysis of variance, Tukey post-hoc test, Chi-Square and Fisher's exact test were used for statistical analysis by Statistical Package for Social Sciences (SPSS) version 16. Results: The mean score of motivation was 90.53 ± 10.76 (range: 59–121). Four motivating factors including “career development” (22.63 ± 5.66), “job characteristics” (34.29 ± 4), “job authority” (18.48 ± 2.79), and “recognition” (15.12 ± 2.5) were recognized. The least mean of the motivation score, considering the number of items, was 3.23 for career development, while the highest mean was 3.81 for job characteristics. Conclusions: The findings showed that motivation of nurses was at a medium level, which calls for improvement. The factors that have the greatest potential to motivate nurses were identified in this study and they can help managers to achieve the goal of continuous quality improvement. PMID:26257797

Currently, the buying and selling of kidneys through "transplant tourism" is occurring at an increasing rate, both in developed and developing countries. Since 1988, Iran has adopted a compensated and regulated living-unrelated donor renal transplant program, and by providing financial incentives to volunteer living donors, has eliminated the renal transplant waiting list. In the Iranian model of renal transplantation program, regulations have been put in place to prevent transplant tourism. Foreigners are not allowed to undergo renal transplantation from Iranian living-unrelated donors. They also are not permitted to volunteer as kidney donors for Iranian patients. A study at the transplant unit of Hashemi Nejad Kidney Hospital in Tehran, Iran, showed that of 1881 renal transplant recipients, 19 (1%) were Afghani or Iraqi refugees, 11 (0.6%) were other foreign nationals, and 18 (0.9%) were Iranian immigrants. Renal transplantations seemed ethically acceptable to all refugees and foreign nationals. However, transplantation of Iranian immigrants who had been residing abroad for years constituted true transplant tourism.

Background Irritable bowel syndrome (IBS) is a gastrointestinal disease that is accompanied by pain, diarrhea, constipation and abdominal bloating. Hence, IBS has a major effect on patients’ quality of life. Objectives The present study aimed to examine validity and reliability of the Persian version of the IBS-QOL questionnaire in Iran. Patients and Methods The original 34 items of the IBS-QOL were translated from English into Persian through a structured procedure for the translation and cultural adaptation of the original English IBS-QOL into Persian. Ninety one patients who had GI symptoms but did not have any organic diseases (including 70 IBS patients diagnosed by Rome II criteria) were recruited from teaching hospitals Shiraz University in Iran and completed a Persian version of the IBS-QOL along with a Persian version of Room ΙΙ and IBS severity index (IBSSI). Results Our findings showed that the IBS-QOL has excellent convergent and acceptable discriminant validity. All domains had Cronbach's alpha greater than 0.7 except health worry. Seventy patients who were diagnosed as IBS by the Room ΙΙ had significantly lower scores in the IBS-QOL than those who were not (FBD) (43.7 ± 20.1 vs. 73.4 ± 14.9, P < 0.01). Age, sex, education or marital status did not affect scores in measuring the quality of life. Conclusions In conclusion, the Persian version of the IBS-QOL provided a well-defined measure of QOL in IBS patients with high validity and reliability that is an appropriate measure to use in further IBS clinical studies in Iran.

The cultural compatibility of sexually related instruments is problematic because the contexts from which the concepts and meanings were extracted may be significantly different from related contexts in a different society. This paper describes the instruments that have been used to assess sexual behaviors, primarily in Western contexts. Then, based on the instruments’ working definition of ‘sexual behavior’ and their theoretical frameworks, we will (1) discuss the applicability or cultural compatibility of existing instruments targeting women's sexual behaviors within an Iranian context, and (2) suggest criteria for sexually related tools applicable in Iranian settings. Iranian women's sexual scripts may compromise the existing instruments’ compatibility. Suggested criteria are as follows: understanding, language of sexuality, ethics and morality. Therefore, developing a culturally comprehensive measure that can adequately examine Iranian women's sexual behaviors is needed. PMID:25250346

Aim: Our aim was to determine the EPIYA-cagA Phosphorylation sites and dupA gene in H. pylori isolates among patients with upper gastrointestinal diseases. Background: Pathogenicity of the cagA-positive Helicobacter pylori is associated with EPIYA motifs and higher number of EPIYA-C segments is a risk factor of gastric cancer, while duodenal ulcer-promoting gene (dupA) is determined as a protective factor against gastric cancer. Patients and methods: A total of 280 non-repeated gastric biopsies obtained from patients undergoing endoscopy from January 2013 till July 2013. Samples were cultured on selective horse blood agar and incubated in microaerophilic atmosphere. The isolated organisms were identified as H. pylori by Gram staining and positive oxidase, catalase, and urease tests. Various motif types of cagA and the prevalence of dupA were determined by PCR method. Results: Out of 280 specimens, 128 (54.7%) isolated organisms were identified as H. pylori. Of 120 H. pylori isolates, 35.9% were dupA positive and 56.26% were cagA positive, while cagA with ABC and ABCC motifs were 55.5% and 44.5%, respectively. Fifty six percent of the isolates with the ABCC motif have had dupA genes. We also found a significant association between strains with genotypes of dupA-ABC and duodenal ulcer disease (p = 0.007). Conclusion: The results of this study showed that the prevalence of cagA-positive H. pylori in Shiraz was as high as in western countries and higher numbers of EPIYA-C segments were seen in gastric cancer patients. We may also use dupA as a prognostic and pathogenic marker for duodenal ulcer disease and cagA with the segment C for gastric cancer and gastric ulcer disease in this region. PMID:26171136

Chromosomal aneuploidy is a well-known phenomenon in human gametes including spermatozoa. Success rate of fertilisation and implantation in subfertile patients with male factor has always been shown to be very low. We tried to relate the possible impact of sex chromosomal aneuploidy in spermatozoa used for intracytoplasmic sperm injection (ICSI) on fertilisation and implantation rate. To evaluate the frequency of disomy for X and Y chromosomes in sperm samples retrieved from normal and oligozoospermic individuals, primed in situ labelling (PRINS) technique was used. Following ICSI, the rate of eight-cell embryos for each category was determined and followed up for successful implantation. Results showed a statistically significant higher frequency of disomy for all chromosomes under study in spermatozoa of oligozoospermic patients compared with normal men (P<0.01). The rate of eight-cells embryo formation was significantly lower than in normal group (P<0.01). The number of embryos transferred for both groups were nearly similar. Implantation rate for oligozoospermic patients was much lower than that of the normal group but was not significantly different (P>0.05). These results demonstrate that men especially with severe oligozoospermia have an elevated risk for chromosome abnormalities in their spermatozoa. These abnormalities might affect fertilisation and pre-embryo formation with less impact on implantation.

Background: Brain death is a concept in which its criteria have been expressed as documentations in Harvard Committee of Brain Death. The various perceptions of caregiver nurses for brain death patients may have effect on the chance of converting potential donors into actual organ donors. Objective: The present study has been conducted in order to perceive the experiences of nurses in care-giving to the brain death of organ donor patients. Methods: This qualitative study was carried out by means of Heidegger’s hermeneutic phenomenology. Eight nurses who have been working in ICU were interviewed. The semi-structured interviews were recorded by a tape-recorder and the given texts were transcribed and the analyses were done by Van-Mannen methodology and (thematic) analysis. Results: One of the foremost themes extracted from this study included ‘Halo of ambiguity and doubt’ that comprised of two sub-themes of ‘having unreasonable hope’ and ‘Conservative acceptance of brain death’. The unreasonable hope included lack of trust (uncertainty) in diagnosis and verification of brain death, passing through denial wall, and avoidance from explicit and direct disclosure of brain death in patients’ family. In this investigation, the nurses were involved in a type of ambiguity and doubt in care-giving to the potentially brain death of organ donor patients, which were also evident in their interaction with patients’ family and for this reason, they did not definitely announce the brain death and so far they hoped for treatment of the given patient. Such confusion and hesitance both caused annoyance of nurses and strengthening the denial of patients’ family to be exposed to death. Conclusion: The results of this study reveal the fundamental perceived care-giving of brain death in organ donor patients and led to developing some strategies to improve care-giving and achievement in donation of the given organ and necessity for presentation of educational and

Statement of the Problem: The prevalence of overweight and obesity has been increasing markedly in recent years. It may influence growth in pre pubertal children. Purpose: The purpose of this study was to determine whether increased Body Mass Index (BMI) is associated with accelerated skeletal maturation and dental maturation in six to fifteen years old orthodontic patients in Shiraz, Iran. Materials and Method: Skeletal maturation and dental development of 95 orthodontic patients (65 females and 30 males), aged 6 to 15 years, were determined. Dental development was assessed using the Demerjian method and skeletal maturation was evaluated by cervical vertebral method as presented by Bacetti. The BMI was determined for each patient. T-test was applied to compare the mean difference between chronologic and dental age among the study groups. A regression model was used to assess the relationship between BMI percentile, skeletal maturation, and dental development. Results: 18.9% of subjects were overweight and obese. The mean differences between dental age and chronologic age were 0.73±1.3 for underweight and normal weight children and 1.8±1.08 for overweight and obese children. These results highlighted the correlation between accelerated dental maturity and increasing BMI percentile (p= 0.002). A new formula was introduced for this relationship. There was not any significant relationship between BMI percentile and skeletal maturation. Conclusion: Children who were overweight or obese had accelerated dental development whereas they did not have accelerated skeletal maturation significantly after being adjusted for age and gender.

Background Male sexual dysfunction is an increasing problem across a variety of general and clinical populations, such as cancer populations; especially among prostate cancer patients who tend to receive treatments that often result in erectile dysfunction (ED) and/or premature ejaculation (PE). Therefore, in order to diagnose ED and PE in these populations, adequate and efficient instruments such as the International Index of Erectile Function 5-item version (IIEF-5) and the Premature Ejaculation Diagnostic Tool (PEDT) are needed. However, since this is an important topic additional evidence of psychometric properties of the IIEF-5 and the PEDT in such samples are required. Thus the aim of the present study was to use Rasch models to investigate the construct validity, local dependency, score order, and differential item functioning (DIF) of both questionnaires in a sample of prostate cancer patients. Methods Prostate cancer patients (n = 1058, mean±SD age = 64.07±6.84 years) who visited urology clinics were invited to fill out the IIEF-5 and the PEDT. Construct validity was examined using infit and outfit mean square (MnSq) and local dependency using correlations between each two residual Rasch scores. Score order was investigated using step and average measures of difficulty and DIF using DIF contrast. Results All IIEF-5 and PEDT items had acceptable infit and outfit MnSq. Step measures revealed that all but two items had disordered categories in terms of scores 1 to 3. Only one local dependency was found, and no items displayed DIF across age, educational level, and help seeking. Conclusions The results showed that both the IIEF-5 and the PEDT had sound psychometric properties in the Rasch analyses, although some score disordering could be detected in both instruments. The results of no DIF items in both instruments suggest using them to compare ED and PE across age and educational level is adequate. PMID:27336626

Background Vesicoureteral reflux (VUR) is a common childhood disorder that is characterized by the abnormal movement of urine from the bladder into the ureters or kidneys. Objectives The aim of this study was to determine whether the genetic polymorphisms of the IL-10, IL-12, and TNF-α genes are involved in the development of VUR. Patients and Methods The tetra amplification mutation refractory system-polymerase chain reaction (Tetra-ARMS PCR) was applied to analyze the four polymorphic sites of the IL-10AG-1082, IL-10CA597, IL-12CA1188, and TNF308GA genes in 124 VUR children and 110 healthy controls. Results A significant, highly increased risk of VUR disease was found for the CA, AA, and combined genotypes of IL-10CA597 (OR = 5.2, 95% CL: 1.80 - 18.25; P = 0.0006, OR = 9.1, 95% CL: 1.11 - 122.75; P = 0.02, OR = 5.3, 95% CL: 1.82 - 18.61; P = 0.00052, respectively); the AG, GG, and AG + GG genotypes of IL-10AG-1082 (OR = 12.8, 95% CL; 2.9 - 113.9; P = 0.00003, OR = 12.62, 95% CL: 2.93 - 114.53; P = 0.00003, respectively); and the AA genotype of IL-12 (AA, OR = 0.19, 95% CL: 0.5 - 0.55; P = 0.0006). The frequency of the C allele in both IL-10CA and IL-12CA was greater in patients with VUR than in the healthy controls. No association was found between TNF308GA and the risk of VUR. Conclusions The results demonstrated significant associations between the IL-10 (AG-1089, IL-10CA) and IL-12 (AA) gene polymorphisms and a highly increased risk of VUR. PMID:27247930
Pre-eclampsia (PE) is a serious multi-factorial disorder of human pregnancy. It is associated with changes in the expression of placental genes. Recent transcription profiling of placental genes with microarray analyses have offered better opportunities to define the molecular pathology of this disorder. However, the extent to which placental gene expression changes in PE is not fully understood. We conducted a systematic review of published PE and normal pregnancy (NP) control placental RNA microarrays to describe the similarities and differences between NP and PE placental gene expression, and examined how these differences could contribute to the molecular pathology of the disease. A total of 167 microarray samples were available for meta-analysis. We found the expression pattern of one group of genes was the same in PE and NP. The review also identified a set of genes (PE unique genes) including a subset, that were significantly (p < 0.05) down-regulated in pre-eclamptic placentae only. Using class prediction analysis, we further identified the expression of 88 genes that were highly associated with PE (p < 0.05), 10 of which (LEP, HTRA4, SPAG4, LHB, TREM1, FSTL3, CGB, INHA, PROCR, and LTF) were significant at p < 0.001. Our review also suggested that about 30% of genes currently being investigated as possibly of importance in PE placenta were not consistently and significantly affected in the PE placentae. We recommend further work to confirm the roles of the PE unique and associated genes, currently not being investigated in the molecular pathology of the disease. PMID:27560381

Blood flow patterns in conduit arteries characterized by high levels of retrograde shear stress can be detrimental for vascular health. In this study we examined whether retrograde shear rate and endothelial function are related in healthy and formerly preeclamptic (PE) women and whether this relationship is altered by exercise training. Formerly PE women (32 ± 4 yr, n = 20) and controls (32 ± 4 yr, n = 20), all 6-12 mo postpartum, performed 12-wk aerobic exercise training. We measured brachial artery shear rate (SR) and endothelial function by flow-mediated dilation (FMD, echo-Doppler). We additionally performed power spectral analysis of heart rate variability and calculated low-frequency/high-frequency (LF/HF) ratio. Antegrade SR was not different between groups, while retrograde SR was significantly higher and FMD% lower in PE women compared with controls (both P < 0.05). Retrograde shear correlated strongly with FMD% in PE women and controls (P < 0.05). LF/HF ratio inversely correlated with brachial artery retrograde SR and FMD% (both P < 0.05) in PE women and controls. Exercise training reduced retrograde shear, improved FMD%, and reduced LF/HF ratios similarly in both groups (all P < 0.05). Training-induced changes in retrograde SR correlated with changes in FMD% and LF/HF ratio. A higher brachial artery retrograde SR relates to lower brachial artery endothelial function, in both controls and formerly PE women. Exercise training improves retrograde SR, while the magnitude of this change correlated strongly with improvements in FMD and reductions in LF/HF ratio. Therefore, the impact of PE and exercise training on endothelial health may, at least partly, be related to retrograde shear rate.

Evidence showed that chemokines serve as pro-migratory factors for immune cells. CCL3, CCL4 and CCL5, as the main CC chemokines subfamily members, activate immune cells through binding to CC chemokine receptor 5 or CCR5. Macrophages, NK cells and T lymphocytes express CCR5 and thus, affected CCR5 expression or functions could be associated with altered immune responses. Deletion of 32 base pairs (Δ 32) in the exon 1 of the CCR5 gene, which is known as CCR5 Δ 32 mutation causes down regulation and malfunction of the molecule. Furthermore, it has been evidenced that three polymorphisms in the promoter region of CCR5 modulate its expression. Altered CCR5 expression in microbial infection and immune related diseases have been reported by several researchers but the role of CCR5 promoter polymorphisms and CCR5 Δ 32 mutation in Iranian patients suffering from these diseases are controversial. Due to the fact that Iranian people have different genetic backgrounds compared to other ethnics, hence, CCR5 promoter polymorphisms and CCR5 32 mutation association with the diseases may be different in Iranian patients. Therefore, this review addresses the most recent information regarding the prevalence as well as association of the mutation and polymorphisms in Iranian patients with microbial infection and immune related diseases as along with normal population.

The right to information Act was implemented in the Iranian legal system through accession of the Merida Convention ensuring the right to information as a fundamental right for the public. One significant aspects of this subject is the ratification of the "Disclosure and Access to Information Act" by which it is recognized as a right of all Persian individuals and citizens to access state-held information in Iran administration. The Iranian legislature, with regard to the role of access to information and its significance, clarified the scope, permitted subjects of access, and exceptions of the right to state-held information. In this essay, we will discuss the legal aspects and scope of ensuring access to medical information in the Iranian statutes and their exceptions. It is argued that the Iranian legislation ensures the principle of maximum disclosure, while sensitive subjects', specially classified and private information, are exempted. Therefore, the related rules in Iran's statutes not only do not threaten patient's information, but also protect them by criminalizing the breaching of the mentioned right.

Women's breast cancer causes various problems in both spouses' family life as well as enormous stress for their husbands. This grounded theory study aimed to define ways in which men adjust to their wives' breast cancer and to present an appropriate model in this respect. Twenty-six individuals (22 husbands, 2 patients and 2 physicians) were selected through purposive and theoretical sampling. The data were collected through in-depth individual interviews. Strauss and Corbin's method was used for data analysis. Data analysis revealed that Iranian men's adjustment to their wives' breast cancer occurs during the following three stages: the first stage turbulence after confrontation with the disease that contains categories 'internal unrest', 'concerns about disease management' and 'sensing the beginning of disorganization in family life'; the second stage disorganisation of family life that contains 'disturbance of family life', 'attempt to get rid of tension' and 'resistance against family life disorganisation'; and the third stage struggle to reorder family life consisting of 'support to the wife', 'revision in communications with relatives' and 'seeking external support' categories. Iranian men struggled for constant organisation of family life after their wives' disease. Health providers should take measures to support the men by facilitating their adjustment to their wives' disease.

Arterial pulse measurement is one of the most important methods for evaluation of healthy conditions. In traditional Iranian medicine (TIM), physician may detect radial pulse by holding four fingers on the patient's wrist. By using this method, under standard condition, the detected pulses are subjective and erroneous, in case of weak and/or abnormal pulses, the ambiguity of diagnosis may rise. In this paper, we present an equipment which is designed and implemented for automation of traditional pulse detection method. By this novel system, the developed noninvasive diagnostic method and database based on the TIM are way forward to apply traditional medicine and diagnose patients with present technology. The accuracy for period measuring is 76% and systolic peak is 72%. PMID:26955566

The programmed cell death-1(PD-1)/PD-ligand 1 (PD-L1) pathway is critical to immune homeostasis by promoting regulatory T (Treg) development and inhibiting effector T (such as Th17) cell responses. However, the association between the PD-1/PD-L1 pathway and the Treg/Th17 imbalance has not been fully investigated in pre-eclampsia (PE). In this study, we observed an inverse correlation between the percentages of Treg and Th17 cells, and the expression of PD-1 and PD-L1 on the two subsets also changed in PE compared with normal pregnancy. We further explored their relationship in vivo using the L-NG-Nitroarginine Methyl Ester (L-NAME) induced PE-like rat models, also characterized by Treg/Th17 imbalance. Administration of PD-L1-Fc protein provides a protective effects on the pre-eclamptic models, both to the mother and the fetuses, by reversing Treg/Th17 imbalance through inhibiting PI3K/AKT/m-TOR signaling and enhancing PTEN expression. In addition, we also observed a protective effect of PD-L1-Fc on the placenta by reversing placental damages. These results suggested that altered PD-1/PD-L1 pathway contributed to Treg/Th17 imbalance in PE. Treatment with PD-L1-Fc posed protective effects on pre-eclamptic models, indicating that the use of PD-L1-Fc might be a potential therapeutic target in PE treatment. PMID:27277012

The expression of endothelial HLA-E in the context of the systemic inflammatory response observed in preeclampsia has not been established. An experimental study was designed to determine the effect of the sera of pregnant women on the expression of HLA-E in EA.hy296 endothelial cells. First, measurements of protein fractions were performed in sera from early-onset, severely preeclamptic women without HELLP syndrome, in which there was no significant difference in total proteins between the groups, but a reduced level of plasma albumin and an increase in α1-globulin were observed in both groups of pregnant women compared with non-pregnant women. Measurements of colloid osmotic pressure (COP) using a recalculated albumin/globulin ratio formula determined only a significant decrease in COP in all pregnant groups compared with non-pregnant women. The expression of membrane HLA-E was increased in EA.hy296 endothelial cells stimulated with sera of early-onset, severely preeclamptic women, while recombinant interferon-γ (IFN-γ) significantly reduced the expression of membrane HLA-E. Pro-inflammatory cytokines were measured by Luminex in the serum samples, and increased levels of tumor necrosis factor (TNF) and decreased levels of IFN-γ were observed in early-onset, severe preeclampsia compared with normal pregnancy. Moreover, soluble HLA-E was detected in these serum samples by Western blot and ELISA, but no significant difference was found. This raises the possibility that a systemic inflammatory response promotes a compensatory mechanism of COP balance in severe preeclampsia by release of inflammation-induced factors, including endothelial HLA-E. Evidence is now provided regarding HLA-E expression by EA.hy296 cells.

Infertility is a medical and psychosocial problem with a high prevalence. There are different treatments for this problem in Iranian traditional medicine. A 28-year-old woman presented with the complaints of 4 emergency operations of the left ovarian cyst during 4 years and infertility. Diagnostic laparoscopy showed an ovarian cyst, adhesion, and endometriosis. Hysteroscopy was unremarkable. After 2 months of letrozole administration, the ovarian cyst ruptured again. Considering the failure of conventional treatments, Iranian traditional medicine products were administered to the patient. After 3 months, the patient conceived and delivered a healthy boy through normal vaginal delivery. These compounds may help with pregnancy as a uterine tonic, vitalizer, and aphrodisiac with brain and cardiac tonic properties.

Understanding the experiences of retired nurses can be useful in increasing self-confidence, motivation to work and work enthusiasm among nurses. The purpose of this study was to explore the work experiences of Iranian retired nurses. A qualitative design was conducted using a content analysis approach. Purposive sampling was used to choose the study participants. Semi-structured interviews were held to collect the perspectives of 20 retired nurses (10 female and 10 male). Two main themes emerged in the data analysis: 'work problems and unpleasant experiences in a sense' with subthemes 'exhausting work', 'insufficient salary', 'inappropriate relation' and 'unsuitable social position'; and 'job satisfaction and pleasant experiences in a sense' with subthemes 'divine satisfaction and religious belief', 'satisfaction of patients and their companions' and 'love of nursing profession and relaxation experience'. The findings indicate the challenges that nurses face after retirement. These experiences will help nurse managers to adopt appropriate measures to support nurses after retirement.

Background: Low health literacy (HL) of patients has obtained more attention as a risk factor for poor adherence to treatment and adverse outcomes in chronic disease's management particular in diabetes care. Diabetes Numeracy Test-15 (DNT-15) has been developed specifically for this purpose. The objective of the current study is to evaluate psychometric properties of Iranian (Persian) version of the DNT-15. Methods: The shortened version of the DNT (15-items) was completed by 120 patients with diabetes. The Kuder–Richardson Formula 20 for internal consistency was conducted. Content validity, criterion-related validity, and construct validity were also evaluated. Results: The average score on the DNT was 72% and took an average of 25 minutes to complete. The DNT-15 had a very good internal reliability (KR-20 = 0.90) and also content validity (content validity ratio: 089 and content validity index: 0.86). Conclusions: The DNT-15 (Persian version) is a reliable and valid measure of diabetes-related numeracy skills for Iranian patients with diabetes; however, additional studies are needed to further explore the association between diabetes-specific numeracy and acculturation and their impact on diabetes-related outcomes in Iranian population.

Purpose of review In this study, we reviewed data on drug use among high school students in Iran. Recent findings Published epidemiological studies in international and domestic journals show that drug use/abuse is a serious mental health problem in Iran. There is cultural support for opium in Iran, and also there is cultural tolerance for tobacco smoking, especially as water pipe smoking, in Iranian families. Alcohol, opium, and cannabis are the most frequently used illicit drugs, but there are new emerging problems with anabolic steroids, ecstasy, and stimulant substances, such as crystal methamphetamine. Summary There is serious drug abuse problem among Iranian high school students. It could be due to role-modeling by parents – mainly fathers – and also cultural tolerance of some substances. Early onset of tobacco smoking, with a daily use rate between 4.4% and 12.8% in high school students, is an important risk factor for other drug abuse problems. Use of all types of drugs, except prescription drugs, is more prevalent among boys. Alcohol is the most frequently abused substance, with a lifetime rate of at least 9.9%. Lifetime rates of opiate use – mostly opium – were between 1.2 an 8.6% in different parts of the country. As drug abuse is a frequent problem among Iranian high school students, it is necessary to design and implement drug prevention programs to protect them. Such programs, including life skills training and drug education, have been operating in recent years for Iranian students from kindergarten to the university level. PMID:20308905

Due to its pivotal geographical location and proximity to transcontinental migratory routes, Iran has played a key role in subsequent migrations, both prehistoric and historic, between Africa, Asia and Europe. To shed light on the genetic structure of the Iranian population as well as on the expansion patterns and population movements which affected this region, the complete mitochondrial genomes of 352 Iranians were obtained. All Iranian populations studied here exhibit similarly high diversity values comparable to the other groups from the Caucasus, Anatolia and Europe. The results of AMOVA and MDS analyses did not associate any regional and/or linguistic group of populations in the Anatolia/Caucasus and Iran region pointing to close genetic positions of Persians and Qashqais to each other and to Armenians, and Azeris from Iran to Georgians. By reconstructing the complete mtDNA phylogeny of haplogroups R2, N3, U1, U3, U5a1g, U7, H13, HV2, HV12, M5a and C5c we have found a previously unexplored genetic connection between the studied Iranian populations and the Arabian Peninsula, India, Near East and Europe, likely the result of both ancient and recent gene flow. Our results for Persians and Qashqais point to a continuous increase of the population sizes from ∼24 kya to the present, although the phase between 14-24 kya is thought to be hyperarid according to the Gulf Oasis model. Since this would have affected hunter-gatherer ranges and mobility patterns and forced them to increasingly rely on coastal resources, this transition can explain the human expansion across the Persian Gulf region.

Motivated by the desire to have more information following the occurrence of damaging events, the main purpose of this article is to study aftershock sequence parameters in the Iranian plateau. To this end, the catalogue of the Iranian earthquakes between 2002 to the end of 2013 has been collected and homogenized among which 15 earthquakes have been selected to study their aftershock decay rates. For different tectonic provinces, the completeness magnitudes ( M c) of the earthquake catalogue have been calculated in different time intervals. Also, the M c variability in spatial and temporal windows has been determined for each selected event. For major Iranian earthquakes, catalogue of aftershocks has been collected thanks to three declustering methods: first, the classical windowing method of Gardner and Knopoff (Bull Seismol Soc Am 64:1363-1367, 1974); second, a modified version of this using spatial windowing based on the Wells and Coppersmith (Bull Seismol Soc Am 84:974-1002, 1994) relations; and third, the Burkhard and Grünthal (Swiss J Geosci 102:149-188, 2009) scheme. Effects of the temporal windows also have been investigated using the time periods of 1 month, 100 days, and 1 year in the declustering method of Gardner and Knopoff (Bull Seismol Soc Am 64:1363-1367, 1974). In the next step, the modified Omori law coefficients have been calculated for the 15 selected earthquakes. The calibrated regional generic model describing the temporal and magnitude distribution of aftershocks is of interest for time-dependent seismic hazard forecasts. The regional characteristics of the aftershock decay rates have been studied for the selected Iranian earthquakes in the Alborz, Zagros and Central Iran regions considering their different seismotectonics regimes. However, due to the lack of sufficient data, no results have been reported for the Kopeh-Dagh and Makran seismotectonic regions.

Background: Inequality in households’ and individuals' consumption expenditures is one of the most important aspects of health status difference among households and individuals. Objectives: We investigated the impact of some macro-economic factors specially inequality factors on the Iranian rural health status since 1986 through 2012. Patients and Methods: We conducted a longitudinal ecological and analytical study. The average sample size was 14602 households whom Iranian Statistics Center selected by a multi-stages clustering sampling approach. All required data has been collected from Iranian Statistics Centre and Deputy for Curial Affaires of Iranian Ministry of Health. We calculated the Gini coefficients for the rural food and health expenditures, then conducted a transloge autoregressive order one (AR1) to investigate the association between the Iranian rural households' key mortality rates and the food and health expenditure Gini coefficients, time trend, GDP per capita (PPP), and GDP per capita Gini coefficients. Results: The mean of Gini coefficients were 0.137 and 0.21 for the rural food expenditures inequality based on current and constant price, respectively. In addition, the mean of Gini coefficients were 0.26 and 0.31 for the rural health expenditures inequality based on current and constant price, respectively. The time trend, transloged form of Gini coefficients for health expenditures and GDP per capita Gini coefficients presented a significant negative correlation with transloged form of neonatal mortality rate. With regard to the transloged form of under five mortality we observed a significant negative correlation with time trend and transloged form of Gini coefficients for health expenditure and GDP per capita. Finally, there was a significant negative correlation between transloged forms of maternal mortality rate. Conclusions: Iranian policy makers should consider the rural health and food expenditures inequality and try to adopt more

Abstract Background Transmission of human pathogens can be occurred via inert objects. Paper currency is a further common contact surface whereby pathogens can be transferred within a population although the significance remains unknown. Hence, the aim of the present study was to investigate microbial populations associated with Iranian paper currency. Methods This study was carried out by getting 108 samples of the Iranian currency notes (1000, 2000, 5000, 10000, 20000 and 50000 RIALS) from food-related shops that included food service outlets, greengrocery, supermarket, bakery, confectionary and poultry meat retail outlets. All currency notes were examined for total bacterial count and identification of pathogenic bacteria. Results The average total bacterial count that was recovered from currency notes was found to be 3.27±0.31 colony forming unites.2000R had the highest total bacterial count, followed by 5000R, 10000R and the lowest in 50000R. In this study, the isolated bacteria recovered were Bacillus cereus (8.33%), E. coli (48.14%), Staphylococcus aureus(28.7%), Salmonella (0.92%), Listeria monocytogenes (0.92%), Yersinia entrocolitica(6.48%). It was revealed that all the pathogens screened for where encountered on currency notes were recovered from one sample. There were no significant (P>0.05) correlations between the carriage of pathogens/fecal indicator bacteria and currency note condition. Conclusion Our findings demonstrate that Iranian currency notes represent a significant vehicle for human pathogens. PMID:26060669

It is well known that arsenic (As) exposure, particularly to inorganic species (i-As), has adverse effects on humans. Nowadays, the European Union (EU) has still not regulated the maximum residue limit of As in commercial samples of rice and rice-based products, although it is actively working on the topic. The European Food Safety Authority (EFSA) is collecting data on total arsenic (t-As) and i-As from different rice-producing regions not only from EU countries but also from other parts of the world to finally set up this maximum threshold. As Iran is a rice-producing country, the aim of this work was to evaluate the contents of t-As and i-As in 15 samples of Iranian white, nonorganic, and aromatic rice collected from the most important rice-producing regions of the country. The means of t-As and i-As were 120 and 82 μg/kg, respectively. The experimental i-As mean in Iranian rice was below the Chinese standard for the i-As in rice, 150 μg/kg, and the Food and Agriculture Organization of the United Nations (FAO) limit, 200 μg/kg. Therefore, Iranian rice seems to have reasonable low i-As content and it is safe to be marketed in any market, including China and the EU.

Background: There is no legal requirement for Iranian military truck drivers to undergo regular visual checkups as compared to commercial truck drivers. Objectives: This study aimed to evaluate the impact of drivers’ visual checkups by comparing the visual function of Iranian military and commercial truck drivers. Patients and Methods: In this comparative cross-sectional study, two hundred military and 200 commercial truck drivers were recruited and their Visual Acuity (VA), Visual Field (VF), color vision and Contrast Sensitivity (CS) were assessed and compared using the Snellen chart, confrontation screening method, D15 test and Pelli-Robson letter chart, respectively. A questionnaire regarding driving exposure and history of motor-vehicle crashes (MVCs) was also filled by drivers. Results were analyzed using an independent samples t-test, one-way ANOVA (assessing difference in number of MVCs across different age groups), chi-square test and Pearson correlation at statistical significance level of P < 0.05. Results: Mean age was 41.6 ± 9.2 for the military truck drivers and 43.4 ± 10.9 for commercial truck drivers (P > 0.05). No significant difference between military and commercial drivers was found in terms of driving experience, number of MVCs, binocular VA, frequency of color vision defects and CS scores. In contrast, the last ocular examination was significantly earlier in military drivers than commercial drivers (P < 0.001). In addition, 4% of military drivers did not meet the national standards to drive as opposed to 2% of commercial drivers. There was a significant but weak correlation between binocular VA and age (r = 0.175, P < 0.001). However, CS showed a significantly moderate correlation with age (r = -0.488, P < 0.001). Conclusions: The absence of legal requirement for regular eye examination in military drivers caused the incompetent drivers to be missed in contrast to commercial drivers. The need for scientific revision of VA standard for

Background The cag pathogenicity island (PAI), which can divide into two parts: cagI and cagII, is the most well-known virulence factor of Helicobacter pylori. Aims We investigated the association between genetic variations within the cag PAI (cagA and cagE in the cagI and cagT in the cagII) and clinical outcomes in Iranian population. Subjects A total of 231 patients including 182 patients with gastritis, 41 with peptic ulcer and 8 with gastric cancer. Methods The presences of the cagA, cagE and cagT genes were measured by polymerase chain reaction and the results were compared with clinical outcomes and gastric histology. Results The cagA, cagE and cagT genes were found in 154 (66.7%), 90 (39.0%) and 70 (30.3%) of clinical isolates. At least 144 (62.3%) strains possessed partially deleted cag PAI (e.g., 69 [29.9%] strains were cagA-positive, but cagE and cagT-negative). Conclusion The simple gene as well as the combination of the genes in the cag PAI appeared not to be useful markers to predict H. pylori-related diseases in Iranian population. The genomic sequences of the cag PAI in Iranian strains might be considerably different from those in other geographic locations. PMID:19261552

Background: Mustard gas has different effects on different body systems such as respiratory tract, blood, gastrointestinal, skin, eye, endocrine and peripheral nervous system. Objectives: The purpose of this study was to determine the quality of life in chemical warfare veterans due to sulfur mustard exposure. Patients and Methods: In a cross-sectional and analytic study, 242 patients who had a chemical injury during the Iran-Iraq war (1980-1983) and their lung damage was proven were investigated in our study. The quality of life was measured in these patients using an extensively validated Iranian version of SF-36. Results: The mean age of veterans was 44.12 ± 4.9 ranging from 22 to 62 years. Our results showed that chemical warfare had a decreased quality of life in all subscales of the SF-36. The lowest scores in SF-36 subscales were related to role physical and general health. The data also showed a significant relationship between the number of organs involved and the quality of life in these patients (P < 0.001, r = − 0.33). So that the patients who had more than three organs involved had lower quality of life. 95.4% of our participants experienced another complication with respiratory complication and the ophthalmologic complications were the most frequent accompanying condition. Conclusions: The results imply that chemical warfare survivors suffering from late complications have a low health related quality of life. PMID:25031863

Background: Investigating the prevalence of diseases and causes of hospitalization of Iranian pilgrims in Iraq can be helpful for healthcare programmers in scheduling a healthy and joyful trip for pilgrims and reducing their mortality and morbidity. Objectives: The main purpose of this study was to determine the frequency of Iranian pilgrims’ referral cases to Karbala and Najaf hospitals in Iraq during a 5-month period in 2012. Patients and Methods: In this cross-sectional study, medical records of all patients referred to Iraqi hospitals from Iranian clinics during a 5-month period from 16 January 2012 until 14 June 2012 was recorded. A checklist, including demographic data and diagnostic causes were prepared and completed by general practitioners. Then, the completed forms were checked and delivered to health surveillance supervisors. Results: A total of 177 referral cases from Iranian clinics to Iraqi hospitals were recorded in 5 months. Most of these referrals were due to cardiovascular diseases with 38.6%, then comes trauma with 26.55%, and finally renal failure in need of dialysis with 12.43%. About 80.2% of the patients were discharged, 13% of them were sent to Iran, and 6.2% died. Around 90% of deaths were due to heart diseases. Conclusions: Considering the high prevalence of cardiovascular diseases and fractures in Iranian pilgrims, the necessity of self-care education to diminish such rates is substantial. PMID:26730348

Objective: This study aimed to provide a normative study documenting how 114 five-seven year-old non-patient Iranian children respond to the Rorschach test. We compared this especial sample to international normative reference values for the Comprehensive System (CS). Method: One hundred fourteen 5- 7- year-old non-patient Iranian children were recruited from public schools. Using five child and adolescent samples from five countries, we compared Iranian Normative Reference Data- based on reference means and standard deviations for each sample. Results: Findings revealed that how the scores in each sample were distributed and how the samples were compared across variables in eight Rorschach Comprehensive System (CS) clusters. We reported all descriptive statistics such as reference mean and standard deviation for all variables. Conclusion: Iranian clinicians could rely on country specific or “local norms” when assessing children. We discourage Iranian clinicians to use many CS scores to make nomothetic, score-based inferences about psychopathology in children and adolescents. PMID:27928247

The United States population is older and more diverse than ever before. Older Immigrant and minorities have been found to suffer from health care disparities. The National Institute of Health (2002) has identified discrimination as one of the factors that contributes to health disparities among immigrants and minority populations. The purpose of this qualitative phenomenological study was to explore older Iranian immigrants' perceptions/experiences of discrimination in their encounter with the American health care system. In depth interviews were conducted with 15 Iranians who had immigrated to the United States after the age of 50. The following major themes emerged from the study: 1) "American doctors don't discriminate", 2) class discrimination in American and Iranian health care system and 3) treating the illness and not the whole person. In general the participants reported that they did not perceive/experience discrimination in their encounter with the American health care system. In fact majority of the participants reported highly positive impressions of American health care providers. Some participants claimed that language barriers may have protected them from recognizing possible discriminations, while others reported that this absence of perceived discrimination may be a function of American provider's perception of a patient as an "illness" and not a whole person.
In 2000, we asked a nationally representative sample of 2,532 Iranian adults "which of the following best describes you: I am an Iranian, above all; I am a Muslim, above all; I am an Arab, a Kurd, a Turk, a Baluch, etc., above all?" We also asked them how proud they are to be Iranian; (1) very proud, (2) proud, (3) not proud, and (4) not proud at all. In the 2005 survey of a nationally representative sample of 2,667 Iranian adults, we asked these questions again. The first question was intended to measure national identity and the second national pride. The results showed that between the two surveys the percent of Iranians who defined themselves as "Iranians, above all" went up significantly-from 35% in 2000 to 42% in 2005. Those who said that they were very proud to be Iranian, on the other hand, went down considerably-from 89% in 2000 to 64% in 2005. What is more, national identity and national pride displayed opposing relationships with the norms and values that were rigorously promoted by Iran's religious regime and these relationships grew stronger between 2000 and 2005. The feeling of national pride was positively linked to attitudes toward gender inequality, religiosity, and religious intolerance, but negatively to attitudes toward the West, while national identity had just the opposite relationships with these variables.

Recording medical histories of patients is not a new issue in clinical medicine. However, the method practiced by the Iranian chemist physician, Rhazes, in the ninth century A.D is incredible. Rhazes has written several textbooks in clinical medicine, but a particular one, "Clinical Stories and Medical Histories" (Qesas va hekayat al-marazi), is a classical case book describing precise clinical courses of thirty three patients. Each chapter includes a title, the name and demographic data about a patient, his/her history of present illness, past medical and family history, findings of physical exam, impression and interventions by the physician, including pharmacological or surgical management. The reasons for each decision made by Rhazes as well as the outcomes are clearly discussed. This book review will shed light on the unknown medical practice methods in Islamic-Iranian golden era.

One of the major advances in medicine has been the use of cardiopulmonary resuscitation (CPR) procedure since the 1960s in order to save human lives. This procedure has so far saved thousands of lives. Although CPR has helped to save lives, in some cases, it prolongs the process of dying, suffering, and pain in patients. This study was conducted to explain the experience of Iranian physicians regarding do not resuscitate order (DNR). This study was a directed qualitative content analysis which analyzed the perspective of 8 physicians on different aspects of DNR guidelines. Semi-structured, in-depth interview was used to collect data (35 to 60 minutes). First, literature review of 6 main categories, including clinical, patient and family, moral, legal, religious, and economic aspects, was carried out through content analysis. At the end of each session, interviews were transcribed verbatim. Then, the text was broken into the smallest meaningful unit (code) and the codes were classified into main categories. The codes were classified into 6 main categories, which were extracted from the literature. In the clinical domain 4 codes, in patient and family 3 codes, in moral domain 4 codes, in religious domain 3 codes, and in economic domain 1 code were extracted. According to the findings of this study, it can be said that Iranian physicians approve the DNR order as it provides dying patients with a dignified death. However, they do not issue DNR order due to the lack of legal and religious support. Nevertheless, if legislators and the Iranian jurisprudence pass a bill in this regard, physicians with the help of clinical guidelines can issue DNR order for dying patients who require it.

Waardenburg syndrome (WS) is a disease of abnormal neural-crest derived melanocyte development characterized by hearing loss and pigmentary disturbances in hair, eyes and skin. WS is subdivided into four major types, WS1-WS4, where WS1 is recognized by the presence of dystopia canthorum, with PAX3 being the only known gene involved. This study aimed at investigating PAX3 mutations and clinical characteristics of WS1 in a group of Iranian patients. A total of 12 WS1 patients from four unrelated Iranian families were enrolled. Waardenburg consortium guidelines were used for WS1 diagnosis. A detailed family history was traced and a thorough clinical examination was performed for all participants. Furthermore, WS1 patients underwent screening for PAX3 mutations using PCR-sequencing. Dystopia canthorum, broad high nasal root and synophrys were observed in all patients. Early graying, hair discoloration, hypoplastic blue eyes (characteristic brilliant blue iris) and hearing loss were the most common features observed, while heterochromia iridis was the least frequently observed sign among the studied Iranian WS1 patients. Genetic analysis of PAX3 revealed four mutations including c.667C>T, c.784C>T, c.951delT and c.451+3A>C. Two of the four mutations reported here (c.951delT and c.451+3A>C) are being reported for the first time in this study. Our data provide insight into genotypic and phenotypic spectrum of WS1 in an Iranian series of patients. Our results expand the spectrum of PAX3 mutations and may have implications for the genetic counseling of WS in Iran.

Introduction: The populations who survive from breast cancer are growing; nevertheless, they mostly encounter with many cancer related problems in their life, especially after early diagnosis and have to deal with these problems. Except for the disease entity, several socio-cultural factors may affect confronting this challenge among patients and the way they deal with. Present study was carried out to prepare clear understanding of Iranian women's lived experiences confronting breast cancer diagnosis and coping ways they applied to deal with it. Methods: This study was carried out by using qualitative phenomenological design. Data gathering was done through purposive sampling using semi-structured, in-depth interviews with 18 women who survived from breast cancer. The transcribed interviews were analyzed using Van Manen’s thematic analysis approach. Results: Two main themes were emerged from the interviews including "emotional turbulence" and "threat control". The first, comprised three sub themes including uncertainty, perceived worries, and living with fears. The second included risk control, recurrence control, immediate seeking help, seeking support and resource to spirituality. Conclusion: Emotional response was the immediate reflection to cancer diagnosis. However, during post-treatment period a variety of emotions were not uncommon findings, patients' perceptions have been changing along the time and problem-focused coping strategies have replaced. Although women may experience a degree of improvement and adjustment with illness, the emotional problems are not necessarily resolved, they may continue and gradually engender positive outcomes.

Background: Pain is one of the most common symptoms experienced by patients after surgeries. Inadequate postoperative pain management is an international problem and the need to improve its management is well documented. The aim of the study was to assess nursing reports related to the patients’ pain intensity and quality, concomitant symptoms, use of scales in pain assessment, and compliance with the national guideline after surgery. Methods: This study was a retrospective cohort; samples were nurse records of patients who had elective surgery. Result: Only 6% of the patients’ pain records included pain intensity which was not measured with standard scales. More than half of all injections were opioid analgesic which is in contrast to the guidelines of the Iranian Ministry of Health. Pain assessment was higher in women and by nurses with more than 15 years of working experience. Conclusion: to conclude, the patients’ pain was not assessed properly in terms of intensity, quality, and associated symptoms. Therefore, training and motivating nurses is very important in this context and should be incorporated in nurses’ academic and continuous educational courses. PMID:27047265

Rhinoplasty is one of the most complicated aesthetic surgeries. One important factor in nasal profile analysis before surgery is the NTP (Nasal Tip Projection). There has been controversy over defining the best tip projection and due to cultural differences there is a need to find the best formulation for Iranian noses. We selected 50 randomized patients. Lateral nasal views were captured from all of the patients. In order to equalize the photos, all tip rotations changed first to 105. We selected four methods for measuring NTP (Goode, Crumley 1, Crumley 2, and Powell and Humphreys). Based on these methods NTP was shown in four pictures. A questionnaire was designed for rating the pictures. Questionnaires were filled in by 3 different groups: rhinoplasty surgeons, general people, and artists. A total of 73 questionnaires were filled in. The analysis and comparison were done. Crumley 2 is the best NTP measurement method from the surgeons' and artists' view. Goode is the method preferred by general people. Powell & Humphreys method seems to be the worst method from all 3 groups' view. It seems that general people prefer smaller noses, because projection in Goode method is almost less than Crumley 2. PMID:27293886

Recently, a few of scientific journals raise serious questions about scientific ethics and moral judgment of some of the Iranian government's senior executives in their papers. Plagiarism, under any circumstances is not justified, and we do not intend to justify it in this note. However, we find it useful in understanding why otherwise respected, responsible individuals may engage in plagiarism by terse review of the history Iranian academia.

Studying the history of science could help develop an understanding of the contributions made by ancient nations towards scientific advances. Although Iranians had an important impact on the improvement of science, the history of Iranian medicine seems not to have been given enough attention by historians. The present study focused on the history of anesthesia and pain management in Iranian medical history. In this regard, related books such as Avesta and Shahnameh were studied in order to obtain the history of anesthesiology in Iranian pre Islamic era. This subject was also studied in the famous books of Rhazes, Haly Abbas, Avicenna, Jorjani, MomenTunekaboni and Aghili from different times of the Islamic era. Scientific data bases such as PubMed, Scopus and Google Scholar were searched using key words "Iranian", "Persian", "pain management" and "anesthesia". It was discovered that pain management and anesthesiology were well known to the Iranians. Rhazes and Avicenna had innovations in this regard. Fourteen Mokhader (anesthetic) herbs, which were included in the collection of the previous knowledge of the 18th century entitled Makhzan al-Advieyh and used as the Persian Materia Medica, were identified and listed. This study introduces the history of anesthesiology and pain management at different periods in the history of Iran.

Interleukin-13 (IL-13) is a TH2 cytokine with direct and indirect immunoregulatory functions on cancer cells. The cytokine has been reported to have some polymorphic variations at the gene level associated with some immune related diseases including asthma and allergy. In the present study, association of three IL13 gene polymorphisms at positions -1512 A/C and -1055 C/T in the promoter and +2044 G/A in exon-4 was investigated in Iranian women with breast cancer and healthy controls. Genotyping of IL13 gene polymorphisms were performed by PCR-RFLP methods. Serum level of IL-13 was assessed by ELISA. Haplotypes were constructed from genotypic data using Arlequin 3.1 software package. Haplotype analysis revealed higher frequency of a three-locus haplotype, ACA (-1512A/-1055C/+2044A), in normal women than breast cancer patients (P < 0.025). Haplotype CCA, from the other hand, was observed with more frequency among patients than controls (P < 0.03). No statistically significant differences were found in the frequency of genotypes and alleles between patients and control group. No association was observed between investigated genotypes and other prognostic factors including tumor type, lymph node involvement and tumor size. IL-13 serum level was undetectable in both patients and control subjects. Despite observing no association between breast cancer and the single SNPs, results of this investigation suggest that the presence of CCA haplotype of IL13 gene may be associated with susceptibility of Iranian women to breast cancer.

Little is known of the parasitic fauna of terrestrial snakes in Iran. This study aimed to evaluate the parasitic infection rates of snakes in Iran. A total of 87 snakes belonging to eight different species, that were collected between May 2012 and September 2012 and died after the hold in captivity, under which they were kept for taking poisons, were examined for the presence of gastrointestinal and blood parasites. According to our study 12 different genera of endoparasites in 64 (73.56%) of 87 examined snakes were determined. Forty one snakes (47.12%) had gastrointestinal parasites. In prepared blood smears, it was found that in 23 (26.43%) of 87 examined snakes there are at least one hemoparasite. To our knowledge, these are the first data on the internal parasitic fauna of Iranian terrestrial snakes and our findings show a higher prevalence of these organisms among them.

Sigrid Fry-Revere's The Kidney Sellers: A Journey of Discovery in Iran, an allegedly first-hand examination of the Iranian paid kidney donation model, has been criticized by Koplin in an essay formerly published in the Monash Bioethics Review. Koplin especially challenges Fry-Revere's claim that financially compensating kidney vendors might facilitate altruistic kidney donation. The current situation in Iran, according to Koplin, suggests that the market model has undermined altruistic donation. On this point, this commentary tries to show that healthcare policymakers in Iran no longer see the Iranian paid kidney donation model as a sustainable and ethically justifiable status quo. Briefly touching on the criticisms that have been made even by some positive commentators of the Iranian model, this commentary aims to call attention to the fact that the current dynamic within healthcare policymaking in Iran seeks primarily to decrease its reliance on the organ market instead of revising and modifying it. This complicates the plausibility of any kind of extrapolation, replication or extracting empirical support from the Iranian model to create organ markets in other countries, for example, as Fry-Revere suggests to conduct a trial of a financially incentivized kidney donation scheme in the US. The conclusion is that the Iranian healthcare system should tackle the organ shortage through increasing altruistic living and postmortem kidney donations. This might also provide, finally, a space for conducting extensive and long-term follow-up studies on well-being, satisfaction and social integration of Iranian kidney vendors.

Purpose: To customize clinical practice guidelines (CPGs) for management of diabetic retinopathy (DR) in the Iranian population. Methods: Three DR CPGs (The Royal College of Ophthalmologists 2013, American Academy of Ophthalmology [Preferred Practice Pattern 2012], and Australian Diabetes Society 2008) were selected from the literature using the AGREE tool. Clinical questions were designed and summarized into four tables by the customization team. The components of the clinical questions along with pertinent recommendations extracted from the above-mentioned CPGs; details of the supporting articles and their levels of evidence; clinical recommendations considering clinical benefits, cost and side effects; and revised recommendations based on customization capability (applicability, acceptability, external validity) were recorded in 4 tables, respectively. Customized recommendations were sent to the faculty members of all universities across the country to score the recommendations from 1 to 9. Results: Agreed recommendations were accepted as the final recommendations while the non-agreed ones were approved after revision. Eventually, 29 customized recommendations under three major categories consisting of screening, diagnosis and treatment of DR were developed along with their sources and levels of evidence. Conclusion: This customized CPGs for management of DR can be used to standardize the referral pathway, diagnosis and treatment of patients with diabetic retinopathy. PMID:27994809

Background: Oral health plays a vital role in people’s general health and well-being. With regard to the costly treatments of oral diseases, preventive programs need to be designed for dental caries based on children’s perspectives. Objectives: The purpose of this study was to describe and explore challenges for caring dental health based on children’s perspectives. Patients and Methods: A qualitative design with content analysis approach was applied to collect and analyze the perspectives of students about factors influencing oral and dental care. Eighteen Iranian students in 8 guidance schools were chosen through the purposive sampling. Semi-structured interviews were held for data gathering. In order to support the validity and rigor of the data, different criteria such as acceptability, confirmability, and transferability were utilized. Results: During data analysis, four main themes developed: “barriers to dental health,” “maintaining dental health,” “uncertainty in decision-making” and “supportive factors”. “Uncertainty in decision-making” and “barriers to dental health” were the main challenges for preventing dental caries among adolescents. Conclusions: “Certainty in decision-making” to maintain dental health depends on overcoming the barriers of dental health. Further research is needed to confirm the findings of this study.

Using dinucleotide repeats for carrier detection and prenatal diagnosis of haemophilia A patients, led us to find different alleles and their frequencies in Iranian population. Polymerase chain reaction (PCR) amplification of two short tandem repeat (STR) loci of factor VIII (FVIII) gene was performed, and the PCR products were resolved on 10% native polyacrylamide gel, and samples were analysed with sequenced DNA markers made of PCR cloning of the dinucleotide FVIII gene fragments. Seven different alleles were observed for intron 13 STR, having 18-24 (CA) repeating units and five alleles for intron 22 STR having 24-28 repeating units of (CACT). Bands produced during dinucleotide study were defined in detail so this could improve the genotyping of heterozygotes and homozygotes. Conformational band produced were characterized to specify the dinucleotide pattern. Our results confirm the Hardy-Weinberg proportions of the heterozygosity rate of the 85 analysed individuals. The observed heterozygosity rate for intron 13 and 22 was 52% and 59% respectively. Our data also indicate that our population is closer to caucasians than to any other populations. Finding different dinucleotide repeat alleles and their frequencies has made it possible to identify carriers and provide prenatal diagnosis with more confidence. This allows antenatal diagnosis to be performed in the vast majority of carriers.

Association of epigenetic modifications with cancer has been widely studied. Gene-specific hypermethylation and global DNA hypomethylation are the most frequently observed patterns in great number of tumors. The methionine synthase (MTR) gene plays key role in maintaining adequate intracellular folate, methionine and normal homocysteine concentrations and, its polymorphism have been associated with the risk of retinoblastoma and other neoplasms. We evaluated the association of MTR A2756G polymorphism with the risk of retinoblastoma in an Iranian population. Totally, 150 retinoblastoma patients and 300 individuals with no family history of cancer as control were included in this study. Genotyping of the A2756G polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) using the restriction enzymes HaeIII. Our results showed that the "G" was the minor allele with a frequency of 31.7% and 20.3% in both retinoblastoma and control groups, respectively. The frequency of the 2756GG genotype (P=0.023) and 2756G allele (P=0.0001) were significantly higher in the patients than control group, respectively. Individual with the 2756GG genotype had a 2.99 fold increased risk for retinoblastoma. According to our results, the MTR A2756G polymorphism was associated with the risk of retinoblastoma in Iranian patients.

Background Iraq is a highly endemic area for the prevalence of hepatitis A and annually hosts a large number of Iranian pilgrims, most of whom are susceptible to infection with the hepatitis A virus (HAV). Objectives This study reports the health hazard of hepatitis A for Iranian pilgrims who go to holly Karbala from the Mazandaran province. Patients and Methods In this cross-sectional study, the data of all patients with acute hepatitis A admitted in the Razi teaching hospital from November 23, 2014 to January 24, 2015, with a history of recently returning from holly Karbala or being exposed to Karbala pilgrims, were registered. Results A total number of nine patients were registered. Seven patients were male and two were female. The mean age was 30.11 ± 10.09.Two patients were from the same family. All patients had typical symptoms of acute hepatitis A. None of the patients died nor did fulminant occur in any patients. In addition, all patients were treated with supportive treatment and subsequently recovered. Conclusions This number of pilgrim patients with acute hepatitis A from a single province compels us to conduct more evaluations and follow up monitoring on all persons travelling to Karbala and be sensitive to early diagnoses of the pilgrims. In the future, it is important to be mindful of administering the HAV vaccine and Ig. PMID:27630729

One decade early onset of the breast cancer in Iranian females was reported but the basis of the observed difference has remained unclear and difference in gene silencing by epigenetic processes is suggested. Hence, this study was sought to map the methylation status of ER gene CpG islands and its impact on clinicopathological factors of triple negative and non-triple negative ductal cell carcinoma of the breast in Iranian females. Surgically resected formalin-fixed paraffin-embedded breast tissues from sixty Iranian women with confirmed invasive ductal carcinoma were assessed by methylation-specific PCR using primer sets encompassing some of the 29 CpGs across the ER gene CpG island. The estrogen and progesterone receptors, Her-2 overexpression, and nuclear accumulation of P53 were examined using immunohistochemistry (IHC). Methylated ER3, ER4, and ER5 were found in 41.7, 11.3, and 43.3% of the samples, respectively. Significantly higher methylation of ER4 was found in the tumors with nuclear accumulation of P53, and significantly higher methylation of ER5 was found in patients with lymph node involvement and tumor with bigger size or higher grades. Furthermore, significantly higher rate of ER5 methylation was found in patients with Her-2+ tumors and in postmenopausal patients with ER-, PgR-, or ER-/PgR- tumors. However, no significant difference in ERs methylation status was found between triple negative and non-triple negative tumors in pre- and postmenopausal patients. Findings revealed that aberrant hypermethylation of ER-a gene frequently occur in Iranian women with invasive ductal cell carcinoma of the breast. However, methylation of different CpG islands produced a diverse impact on the prognosis of breast cancer, and ER5 was found to be the most frequently methylated region in the Iranian women, and could serve as a marker of poor prognosis.

Background: Evidence has shown a link between allergic disease and inflammatory bowel diseases (IBDs). We investigated food allergy in Iranian pediatric IBD patients. Materials and Methods: A cross-sectional study was conducted on a consecutive sample of children with newly diagnosed IBD referring to Mofid Children's University Hospital in Tehran (Iran) between November 2013 and March 2015. Data on age, gender, history of cow's milk allergy (CMA), IBD type, routine laboratory tests, and colonoscopic and histopathological findings were gathered. Food allergy was assessed with the skin prick test (SPT). Results: A total of 28 patients including 19 ulcerative colitis (UC), 7 Cronh's disease (CD), and two with unclassified colitis with a mean age of 8.3 ± 4.4 years. (57.1% females, 42.9% were studied. History of CMA was present in eight patients (28.6%). Seventeen patients (60.7%) had at least one food allergy (68.4% of UC vs. 42.9% of CD, P = 0.230). Ten patients (35.7%) had multiple food allergies (36.8% of UC vs. 42.9% of CD, P > 0.999). Common allergic foods were cow's milk (28.6%), beef, seafood, albumen, wheat, and walnuts (each 10.7%), and peanuts and chestnuts (each 7.1%). The SPT showed CMA in 68.4% (8/17) of UC but none of the CD patients (P = 0.077). Conclusion: Food allergy is frequent in Iranian pediatric IBD patients with CMA being the most common observed allergy. The CMA seems to be more frequent in UC than in CD patients. PMID:26759572

Objective: The periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome is a nonhereditary idiopathic febrile syndrome belonging to the group of autoinflammatory diseases. No longtime sequel was reported in this disease. Early diagnosis can lead physicians to treatment of this disorder with a short course steroid application and provide satisfaction of the patient’s family. Methods: This study is a prospective review of patients diagnosed with PFAPA syndrome who were registered in Iranian Periodic Fever and Autoinflammatory Registry (IPFAIR) through periodic fever clinic in the Children's Medical Center, Pediatric Center of Excellence in Tehran, Iran from January 2013 to March 2014. Findings: One hundred thirty patients were registered in our databases. Twenty-one (16.1%) patients including 15 males and 6 females had PFAPA. Normal growth was seen in all patients. The median age at onset was 18 months. The mean duration of fever was 4 days and the mean duration of intervals between fever episodes 21 days. Along with fever, all patients had characteristic symptoms. All patients were asymptomatic between fever episodes. Steroid was used in all patients and causing immediate reduction by 84.61%. Two patients received both steroid and colchicine because of their clinical feature and positive laboratory tests for PFAPA and familial Mediterranean fever. No patient received biological therapy or a tonsillectomy. Conclusion: The long diagnostic delay of PFAPA gives cause to concern indicating a need for greater awareness of the disease so that the diagnosis may be made timely. PMID:25793068

Introduction Celiac disease (CD) is caused due to intake of gluten, a protein component in wheat, barley, and rye. The only treatment currently available for CD is strict lifetime adherence to a gluten-free diet (GFD) which is a diet that excludes wheat, barley, and rye. There is limited information on barriers to following a GFD. The present study aimed to investigate the compliance with a GFD, barriers to compliance, and the impact of compliance on the quality of life (QOL) in Iranian children and adolescents suffering from CD. Methods In this cross-sectional study, a total of 65 known cases of CD (both males and females), diagnosed in Namazi Hospital, a large referral center in south of Iran, selected by census were studied in 2014. Dietary compliance was assessed using a questionnaire. A disease-specific QOL questionnaire for children with CD (the celiac disease DUX [CDDUX]) was used. Comparisons between categorical variables were performed using chi-square test. Results Sixty-five patients, 38 females (58.5%) and 27 (41.5%) males, were surveyed. Mean (± standard deviation [SD]) age of the respondents was 11.3 (±3.8) years. Dietary compliance was reported by 35 (53.8%) patients. The mean (± SD) CDDUX score was higher in dietary-compliant patients (33.5 [±19.4] vs 26.7 [±13.6], respectively, P=0.23). The score of CDDUX in parents of patients in dietary-compliant group was more than the noncompliant patients (28.1 [±13.5] vs 22.1 [±14], respectively, P=0.1). Barriers to noncompliance were poor or unavailability (100%), high cost (96.9%), insufficient labeling (84.6%), poor palatability (76.9%), and no information (69.23%). Conclusion Approximately half of the patients with CD reported dietary compliance. Poor or unavailability was found to be the most important barrier contributing to noncompliance. The QOL was better in compliant patients. Proposed strategies to improve compliance are greater availability of gluten-free products, better food labeling, and

ABSTRACT Herein, we evaluated whether Placental Mesenchymal Stromal Cells (PDMSCs) derived from normal and Preeclamptic (PE) placentae presented differences in the expression of G1/S-phase regulators p16INK4A, p18INK4C, CDK4 and CDK6. Finally, we investigated normal and PE-PDMSCs paracrine effects on JunB, Cyclin D1, p16INK4A, p18INK4C, CDK4 and CDK6 expressions in physiological term villous explants. PDMSCs were isolated from physiological (n = 20) and PE (n = 24) placentae. Passage three normal and PE-PDMSC and conditioned media (CM) were collected after 48h. Physiological villous explants (n = 60) were treated for 72h with normal or PE-PDMSCs CM. Explants viability was assessed by Lactate Dehydrogenase Cytotoxicity assay. Cyclin D1 localization was evaluated by Immuofluorescence (IF) while JunB, Cyclin-D1 p16INK4A, p18INK4C, CDK4 and CDK6 levels were assessed by Real Time PCR and Western Blot assay. We reported significantly increased p16INK4A and p18INK4C expression in PE- relative to normal PDMSCs while no differences in CDK4 and CDK6 levels were detected. Explants viability was not affected by normal or PE-PDMSCs CM. Normal PDMSCs CM increased JunB, p16INK4 and p18INK4C and decreased Cyclin-D1 in placental tissues. In contrast, PE-PDMSCs CM induced JunB downregulation and Cyclin D1 increase in placental explants. Cyclin D1 IF staining showed that CM treatment targeted mainly the syncytiotrophoblast. We showed Cyclin D1-p16INK4A/p18INK4C altered pathway in PE-PDMSCs demonstrating an aberrant G1/S phase transition in these pathological cells. The abnormal Cyclin D1-p16INK4A/p18INK4C expression in explants conditioned by PE-PDMSCs media suggest a key contribution of mesenchymal cells to the altered trophoblast cell cycle regulation typical of PE pregnancies with fetal-placental compromise.

Background: The second leading cause of cancer deaths in women is breast cancer. Germline mutations in susceptibility breast cancer gene BRCA1 increase the lifetime risk of breast cancer. Eighty-one large genomic rearrangements (LGRs) have been reported up to date in BRCA1 gene, and evaluation of these rearrangements helps with precise risk assessment in high-risk individuals. In this study, we have investigated LGRs in BRCA1 among Iranian high-risk breast cancer families. Materials and Methods: Seventy patients with breast cancer who were identified negative for point mutations or small deletions/insertions of BRCA1 gene were selected. Deletions and duplications of BRCA1 gene were evaluated using multiplex ligation-dependent probe amplification (MLPA). Results: Two deletions, deletion of exons 1A/1B-2 and exon 24, were detected in two patients with breast cancer. The former alteration was found in a woman with a strong family history of breast cancer while the latter one was detected in a woman with early onset of breast cancer. Conclusion: Although our data confirm that LGRs in BRCA1 comprise a relatively small proportion of mutations in hereditary breast cancer in the Iranian population, MLPA analysis might be considered for screening of LGRs in high-risk individuals. It is worth to note that our results are consistent with previous studies in various Asian and European countries. PMID:28163741

The genetic association between cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations and male infertility due to congenital bilateral absence of vas deferens (CBAVD) is well established. Mutant CFTR, however may also be involved in the etiology of male infertility in non-CBAVD cases. The present study was conducted to estimate the frequency of ∆I507 and ∆F508 CFTR gene mutations in Iranian infertile males. We undertook the first study of association between these CFTR mutations and non-obstructive azoospermia in Iran. In this case-control study, 100 fertile healthy fathers and 100 non-obstructive azoospermia’s men were recruited from Isfahan Infertility Center (IIC) and Sari Saint Mary’s Infertility Center, between 2008 and 2009. Screening of F508del and I507del mutations was carried out by the multiplex-ARMS-PCR. Significance of differences in mutation frequencies between the patient and control groups was assessed by Fisher’s exact test. The ΔF508 was detected in three patients. However there are no significant association was found between the presence of this mutated allele and infertility [OR=9.2 (allele-based) and 7.2 (individual-based), P=0.179]. None of the samples carried the ΔI507 mutation. Altogether, we show that neither ΔI507 nor ΔF508 is involved in this population of Iranian infertile males with non-obstructive azoospermia.

Kidney transplantation has become the treatment of choice for patients with end-stage renal disease. Six decades of success in the field of transplantation have made it possible to save thousands of lives every year. Unfortunately, in recent years success has been overshadowed by an ever-growing shortage of organs. In the United States, there are currently more than 100 000 patients waiting for kidneys. However, the supply of kidneys (combined cadaveric and live donations) has stagnated around 17 000 per year. The ever-widening gap between demand and supply has resulted in an illegal black market and unethical transplant tourism of global proportions. While we believe there is much room to improve the Iranian model of regulated incentivized live kidney donation, with some significant revisions, the Iranian Model could serve as an example for how other countries could make significant strides to lessening their own organ shortage crises.

Delayed neurotoxic complications of chemical warfare agents (CWA), such as sulphur mustard (SM) and tabun, in human beings have not been reported in detail. We thus aimed to investigate possible neurotoxic complications of these agents in Iranian veterans 22-27 years after exposure. After co-ordination with the veteran foundation and obtaining the approval of the medical research ethics committee, 43 Iranian veterans with late complications of CWA exposure during the Iran-Iraq conflict were studied after obtaining signed written informed consent. Demographic and clinical findings were recorded on pre-designed forms. Neurological examination was performed by a neurologist. Routine biochemical tests were performed for all the patients. Electromyography (EMG), nerve conduction velocity (NCV) and electroencephalography (EEG) were carried out as clinically indicated. The majority of the patients (38) had been exposed to SM and only five patients to tabun. Hyperaesthesia was the most objective finding (72.1%). Fatigue (93%), paraesthesia (88.3%) and headache (83.7%) were the most common subjective findings in the patients. Sensory nerve impairments, including paraesthesia (88.3%), hyperaesthesia (72.1%) and hypoesthesia (11.6%), were the most common observed clinical complications. EMG and NCV were impaired in seven patients (16.3%) who were all SM-exposed patients but did not show any significant correlation with organ complications. EEG was negative even in the seized patients. Cholesterol, LDL and triglyceride levels were significantly above the normal ranges. Late neurological complications of CWA, particularly SM poisoning, are considerable even after three decades of exposure and require medical attention.
The Human Genome Project (HGP) refers to the international scientific research program, formally begun in October 1990 and completed in 2003, mainly designated to discover all the human genes, analyzing the structure of human DNA and determining the location of all human genes and also making them accessible for further biological and medical investigations. With the appropriate rationale approach, a similar study has been held in Iran. The study of human genome among Iranian ethnicities (IHGP) has been attempted formally in 2000 through a detailed and fully programmed research among all the major ethnic groups by more than 1,900 samples from all over Iran based on the main demographical and anthropological findings and formally known criteria considered for the international HGP. This paper overviewed the process of the research in the terms of program goals, primary data collection, research designation and methodology and also practical aspects and primary findings of the Iranian genome project and its progress during a nearly 5-year period.

The major difference between Iranian traditional medicine and allopathic medicine is in the application of evidence and documents. In this study, criteria for evidence-based practice in Iranian traditional medicine and its rules of practice were studied. The experts' views were investigated through in- depth, semi-structured interviews and the results were categorized into four main categories including Designing clinical questions/clinical question-based search, critical appraisal, resource search criteria and clinical prescription appraisal. Although the application of evidence in Iranian traditional medicine follows Evidence Based Medicine (EBM) principles but it benefits from its own rules, regulations, and criteria that are compatible with EBM.

In this work, the volatile profiles of smoked and non-smoked Iranian rice were identified, and their relative abundance was calculated and compared. Headspace solid-phase microextraction together with gas chromatography-mass spectrometry (SPME-GC-MS) were used to extract and identify the volatile compounds. The main groups of volatiles in Iranian rice were aldehydes, ketones, phenol derivatives, furans, linear hydrocarbons, esters and terpenes. The chemical family aldehydes was the most abundant one in the profile of non-smoked rice, while phenol derivatives and furans predominated in smoked samples. This study is the first one reporting comparative data of volatile compounds between smoked and non-smoked Iranian rice. PMID:28231176

The number of women attending institutions of higher education in Iran has been steadily increasing since 1989. Growing enrollment rates for women in colleges and universities have sparked wide social and political debates in that country. The basic question of why young Iranian women might even choose to pursue tertiary education, however, has not been adequately addressed in the critical literature. This study gives voice to young women who explain for themselves why they are interested in higher education. It reveals that college or university studies represent for female students many things: a sphere of hope, a refuge, and a place to experience limited freedom beyond restrictive family environments; an asset that can increase a woman's value in the marriage market; a right that may make possible financial independence; and a vehicle that can earn respect for women. On the whole, the desire for higher education illuminates the challenges facing women in Muslim nations and the ways in which Muslim women are using this institution to change their social status.

Background: Recently, quality is a serious concern in development of organizations. There are various indicators to assess quality and the purpose of this study was to identify the main indicators for quality measurement of Iranian health centers. Methods: This qualitative study was conducted in three stages: first, review of the literature was performed to identify different indicators for quality measurement in health centers; second, a tworound Delphi process was used with participation of 18 experts in both rounds; third, Analytical Hierarchy Process (AHP) method was applied to give weights to each indicator. Results: Twenty-seven indicators were identified from the literature review stage. The Delphi method reduced the list to 4 indicators. Developing a quality plan in the health center had the highest weight (38%) and percentage of followed complaints the lowest (12%). The consistency rate was 7.2% indicating appropriateness of the data. Conclusion: This list of indicators can be used as a template for measuring quality of health centers in Iran and possibly in other developing countries. PMID:26034730

After four years of publishing the Iranian National Laboratory Standard and following a strategic plan to implement its requirements, it was decided to review the taken actions, evaluating the achievements and the failures, as well as analyzing the gaps and planning the interventional activities to resolve the problems. A thorough evaluation revealed that the progress of implementation process varies considerably in different provinces, as well as in laboratories in different public and private sectors. Diversity and heterogeneousity of laboratories throughout the country is one of unresolvable problems. Although we encounter shortage of resources in the country, improper allocation or distribution of resources and budgets make the problems more complicated. Inadequacy of academic training in laboratory sciences has resulted in necessity of holding comprehensive post-graduate training courses. Revising academic curriculum of laboratory sciences could be mostly helpful, moreover there should be organized, training courses with pre-determined practical topics. providing specific technical guidelines, to clarify the required technical details could temporarily fill the training gaps of laboratory staff. Inadequate number of competent auditors was one of the difficulties in universities. Another important challenge returns to laboratory equipment, developing the national controlling system to manage the laboratory equipment in terms of quality and accessibility has been planned in RHL. At last cultural problems and resistance to change are main obstacles that have reduced the pace of standardization, it needs to rationalize the necessity of establishing laboratory standards for all stakeholders.

In the present study, factors that could play an important role in Internet addiction (IA) in 4,177 Iranian high school and secondary school adolescents (age range: 14-19 years) were examined. Data for the present study were gathered through Young's IA test, the General Health Questionnaire (GHQ), and family relationship questionnaires distributed between high school and secondary school students in different demographic regions, carefully selected using multistage sampling techniques. Among the study participants, 21.1% of the students were in some way victims of IA, among whom 1.1% had significant problematic symptoms. Familial relationships was the most important factor related to IA; religious beliefs, moreover, was the second most important factor. The father's level of education was more important than that of the mother's by nearly twice as much. Other factors had important roles in the kind of Internet use, but not as much as the above mentioned factors. The findings of this study could help parents, school counselors, and teachers to pay more attention to excessive Internet use in adolescents and propose possible solutions.

A 46-year-old man of Iranian origin presented with a 4-day history of colicky abdominal pain and absolute constipation on a background of several weeks of irritability and malaise. He had smoked 10 g of opium per week for a year and a half. On examination, he had diffuse abdominal tenderness and faecal loading. This was cleared, but the abdominal pain, nausea and vomiting persisted. He had extravascular haemolytic anaemia with punctate basophilic stippling on blood film. The patient's serum lead concentration was substantially elevated and he perhaps demonstrated Burton's line. The patient underwent chelation therapy and has recovered clinically and biochemically. Public health experts were notified and conducted an assessment of the risk to the patient and others; their lead exposure questionnaire was subsequently amended. This is an important case report of a UK resident describing lead toxicity secondary to the inhalation of opium.

Background Hereditary multiple osteochondromas (HMO), previously named hereditary multiple exostoses (HME), is an autosomal dominant skeletal disorder characterized by the growth of multiple osteochondromas and is associated with bony deformity, skeletal growth reduction, nerve compression, restriction of joint motion, and premature osteoarthrosis. HMO is genetically heterogeneous, localized on at least three chromosomal loci including 8q24.1 (EXT1), 11p11-p13 (EXT2), and 19p (EXT3). The median age of diagnosis is 3 years; almost all affected individuals are diagnosed by age 12. The risk for malignant degeneration to osteochondrosarcoma increases with age, although the lifetime risk of malignant degeneration is low (~1%). Methods and results This study was performed on an Iranian family with nine affected individuals from three consecutive generations. Here, the proband was an affected woman who received genetic counseling prior to pregnancy. All exons of the three genes were examined in the proband using polymerase chain reaction and sequencing methods (the last member of this family is a male with severe deformities and lesions, especially around his large joints). Exon 4 of EXT1 (c.1235 G>A) was changed in affected individuals. This mutation alters tryptophan to a premature stop codon on amino acid position 412 (p.Trp412x). Conclusion The outcome of this study has extended the genotypic spectrum of Iranian patients with HMO, revealing a way for improving detection and genetic counseling in carriers. PMID:28053536

Background: There are restrictions as well as lawful and religious prohibition for sexual relationships in Iranian society. Objectives: This study explores the varied experiential reality of Iranian youth and their risky sexual experiences. Patients and Methods: Data collection is based on semi-structured interviews with 30 single young men and women. Observation of interactions of youth in different settings has been another source of information. Interviews were microscopically content analyzed. Results: The accounts of risky sexual experiences included gendered behavioral, cultural, and cognitive factors. In the re-contextualizing process, these accounts were categorized by two main themes: “gendered sexual script” and “cultural scenarios of interpersonal interactions”. The notion of “male power” was evident in the responses provided by the participants. Women seldom asked for condom use due to limited knowledge about STIs-HIV/AIDS and unpleasant experiences with condoms. Men had limited knowledge about various sexual modes of HIV and STIs transmission and did not use condoms consistently because they had not seen themselves at risk of STIs or HIV as well as their belief about the decrease of sexual pleasure. Conclusions: Rising youth awareness, creating a positive attitude, and appropriate knowledge about safe sex practices are seminal. It is also vital to ensure access to gender specific sexual and reproductive health services for youths, empower women, and strengthen their sexual assertiveness as well as the elimination of all forms of gender-based inequalities.

Background: Decision making for timing motherhood is one of the vital aspects of reproductive health. Separating sexual relationship from having a child has led to a different and unprecedented lifestyle in human history. Objectives: The objective of this study was to determine the socioeconomic and emotional factors predicting decision making for timing motherhood among Iranian women using the statistical softwares of IBM SPSS 21 and LISREL 8.8. Patients and Methods: This cross-sectional study enrolled 820 primiparous women from different hospitals across the country using multistage random sampling method in 2013. The tools of the study were enrich marital satisfaction, socioeconomic status, perceived social support, hopefulness, and life regard index. The data was analyzed using SPSS 20 and LISREL 8.8. Results: The results revealed that among direct pathways, marital age (β = 0.62) was the most effective predictor of timing motherhood. The hopefulness had an inverse association with timing motherhood through inverse effect of marital satisfaction. Moreover, marital satisfaction (β = -0.09), perceived social support (β = -0.09), and life regard index (β = 0.01) had an inverse effect on timing motherhood. Marital satisfaction had a non-causal effect of 0.024. Conclusions: Marital age, and socioeconomic status had a direct association, and hopefulness and marital satisfaction had an indirect one with Iranian women’s decision for timing motherhood. Therefore, this is the responsibility of policy-makers and healthcare providers to advise women by providing appropriate interventions and facilities. PMID:24719733

Introduction: Having knowledge about the anatomy of root canal system is essential for success of endodontic treatment. The present study used cone-beam computed tomography (CBCT), to evaluate the prevalence of third root in mandibular first molars in a selected Iranian population. Methods and Materials: A total of 386 CBCT images from subjects referred to oral and maxillofacial radiology department of dental faculty of Tabriz University of Medical Sciences from 2011 to 2013 were selected and evaluated for this study and the cases with well-developed permanent mandibular first molars were included. The 3D images were reconstructed in axial cross sections and evaluated by two endodontists for the presence of the third extra lingual (radix entomolaris) or buccal (radix paramolaris) root. The chi-squared test was used to evaluate the relationship between gender and bilateral incidence of extra roots in mandibular first molars. Results: The distribution of three-rooted mandibular first molars with an additional root was 3%, (3.53% in female and 2.50% in male patients). There was no significant relationship between gender and bilateral occurrence of three-rooted mandibular first molars. Conclusion: The occurrence of three-rooted mandibular first molars in Iranian population is not uncommon which should be taken into consideration by the dental practitioners during root canal treatment of these teeth.

Establishing an appropriate prophylaxis regimen for children with hemophilia is a critical challenge in developing countries. Barriers including availability and affordability, catheter-related complications, and inhibitor development risks have led to the introduction of new tailored prophylaxis regimens in different countries. This study emphasizes on the benefits of the Iranian low-dose escalating prophylaxis regimen in a Hemophilia Comprehensive Care Center in Iran. Referred patients with hemophilia less than 15 years of age, who were subject to prophylaxis regimen, are studied retrospectively. A once-weekly prophylaxis regimen of 25 IU/kg was started for the patients primarily. Their prophylaxis regimen was changed to 25 IU/kg twice a week and then 3 times a week when they experienced 3 joint bleedings, 4 soft tissue bleedings, or a 1 life-threatening bleed without a specific trauma history. Overall, 25 patients with severe hemophilia and at least 6-month history of on-demand (OD) treatment were studied. A mean of 1754 IU/kg/yr of coagulation factors, used for OD and prophylaxis purposes, was sufficient to decrease the mean annual bleeding rate (ABR) to 1.86 after prophylaxis. It also reduced the mean hospitalization days and the mean number of target joints to 0.24 and 0.16, respectively. Overall, 19 (76%) patients were continuing their once-weekly regimen at the end of the follow-up. None of the patients needed 3-times-a-week regimen or central venous catheterization and none developed inhibitors in the follow-up. Benefits of the Iranian low-dose escalating prophylaxis regimen prove equal to some of the previous 3-times-a-week prophylaxis regimens in reducing the ABR and hospitalizations.

Surprisingly little is known about the detailed velocity structure of Iran, despite the region's importance in the tectonics of the Middle East. Previous studies have concentrated mainly on fundamental mode surface wave dispersion measurements along isolated paths (e.g.~Asudeh, 1982; Cong & Mitchell, 1998; Ritzwoller et.~al, 1998), and the propagation characteristics of crust and upper mantle body waves (e.g. Hearn & Ni 1994; Rodgers et.~al 1997). We use the partitioned waveform inversion method of Nolet (1990) on several hundred regional waveforms crossing the Iranian region to produce a 3-D seismic velocity map for the crust and upper mantle of the area. The method consists of using long period seismograms from earthquakes with well determined focal mechanisms and depths to constrain 1-D path-averaged shear wave models along regional paths. The constraints imposed on the 1-D models by the seismograms are then combined with independent constraints from other methods (e.g.~Moho depths from reciever function analysis etc.), to solve for the 3-D seismic velocity structure of the region. A dense coverage of fundamental mode rayleigh waves at a period of 100~s ensures good resolution of lithospheric scale structure. We also use 20~s period fundamental mode rayleigh waves and some Pnl wavetrains to make estimates of crustal thickness variations and average crustal velocities. A few deeper events give us some coverage of higher mode rayleigh waves and mantle S waves, which sample to the base of the upper mantle. Our crustal thickness estimates range from 45~km in the southern Zagros mountains, to 40~km in central Iran and 35~km towards the north of the region. We also find inconsistencies between the 1-D models required to fit the vertical and the tranverse seismograms, indicating the presence of anisotropy.

To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (White Marandi, Black Marandi, Naked Neck, Common Breed, Lari, West Azarbaijan, and New Hampshire) native chicken breeds, together with the available reference sequences of G. gallus gallus in GenBank. The haplotype diversity was estimated as 0.24±0.01 and 0.36±0.02 for Turkish and Iranian populations, respectively. In total, 19 haplotypes were observed from 24 polymorphic sites in Turkish and Iranian native chicken populations. Two different clades or haplogroups (A and E) were found in Turkish and Iranian chickens. Clade A haplotypes were found only in White Marandi, Common Breed and New Hampshire populations. Clade E haplotypes, which are quite common, were observed in Turkish and Iranian populations with 18 different haplotypes, of which Turkish and Iranian chickens, Clade E, haplotype 1 (TRIRE1) was a major haplotype with the frequency of 81.5% (181/222) across all breeds. Compared to red jungle fowl, Turkish and Iranian chicken breeds are closely related to each other. These results suggest that Turkish and Iranian chickens originated from the same region, the Indian subcontinent. Our results will provide reliable basic information for mtDNA haplotypes of Turkish and Iranian chickens and for studying the origin of domestic chickens. PMID:27189637

Aggression from psychiatric patients is a constant problem for care providers that causes major problems in the therapeutic environment, and may have negative effects on the quality of care. Since recognition of aggression with regard to cultural background leads to better control of aggression in the psychiatric wards, this study has been done to clarify Iranian nurses' experiences of aggression in psychiatric wards. A qualitative content analysis study was conducted to explore experiences of nurses. Data analysis revealed four themes: (1) Damage resulting from aggression, (2) Aggression catalysts, (3) Contagious nature of aggression, and (4) Various control strategies. There are various causes for in-patients' aggression, and nurses use various approaches to control it. These approaches are influenced by personnel, facilities, and ward environment. Identifying these factors and strategies can contribute to better management of aggression and, thus, better quality of care in psychiatric wards.

We have constructed and validated regional wave (Pg and Lg) attenuation models for the crust and upper mantle throughout the Iranian plateau and surrounding regions. This research has increased ray path coverage of critical areas and help to create robust regional phase amplitude and attenuation models. We have recently combined our Iranian data set with our existing Middle Eastern Lg waveform database including stations from the recent CDCAT seismic experiment in central Anatolia. Together, these two data sets give us reasonably good coverage of the northern Middle East using both a two-station and reverse-two-station (RTM) attenuation measurements. We have also processed Pg waveforms in order to obtain robust estimates of Qp in the crust within the Anatolian-Iranian plateau. In general we have found a good correlation between Lg and Pg Q values with the exception of northwestern Iran. We are using our models of Qp and Qs for the crust to better understand the origin of the crustal models and to help determine the origin of the seismic anomalies in the crust beneath the Turkish-Iranian Plateau. We will correlate our Q models with variations in seismic wave speed from ambient noise tomography and local body wave tomography to understand whether composition or temperature anomalies are generating the observed seismic anomalies.

Background: Role of diet on colorectal cancer (CRC) has been considered in terms of single foods and nutrients, but less frequently in terms of dietary patterns in Iran. The objective of this study was to determine the association between Iranian dietary patterns and CRC. Methods: This case–control study was conducted in four hospitals in Tabriz City of Iran including 414 participants aged 35–75 years:207 cases with CRC confirmed by pathology and colonoscopy findings were selected and 207 controls free of neoplastic conditions and diet-related chronic diseases (from the same hospital at the same period for the cases). Dietary data were assessed using a 123-item semi-quantitative food frequency questionnaire. Two dietary patterns were found by using of Principal Component Analysis (PCA) method;“Healthy pattern”and “Iranian pattern”. Multivariate logistic regression analysis was used to estimate adjusted odds ratios (OR) for relationship between dietary patterns and colorectal cancer. Results: After adjusting for confounding factors, the Iranian dietary pattern was significantly associated with an increased odds of colorectal cancer (OR= 1.46; 95% Confidenec Interval (CI)=1.05–2.19) while a reduced odds of colorectal cancer was observed with the Healthy dietary pattern (OR=0.18; 95% CI= 0.091-0.47). Conclusion: Iranian dietary pattern (IDP) seems to increase the odds of colorectal cancer and protective effect of Healthy dietary pattern. PMID:26000248

Transplant tourism is one of the main unacceptable aspects of medical tourism, implicating travel to another country to receive an allograft. Organ shortages in wealthier countries have persuaded patients to preclude organ waiting lists and travel to other countries for getting organs especially kidneys. On the other hand, in many countries, there is no transplant program, and hemodialysis is expensive. Hence, patients with end-stage kidney disease may have to travel to get a kidney allograft for the sake of their lives. In Iran, a legal compensated and regulated living unrelated donor kidney transplant program has been adopted since 1988, in which recipients are matched with liveunrelated donors through the Iran Kidney Foundation and the recipients are compensated dually by the government and the recipient. In this model regulations were adopted to prevent transplant tourism: foreigners were not allowed to receive a kidney from Iranian donors or donate a kidney to Iranian patients; however, they could be transplanted from donors of their own nationality, after full medical workup, with the authorization of the Ministry of Health. This was first considered as a humanitarian assistance to patients of the countries with no transplant program and limited and low quality dialysis. However, the policy of "foreign nationality transplant" gradually established a spot where residents of many countries, where living-unrelated donor transplant was illegal, could bring their donors and be transplanted mainly in private hospitals, with high incentives for the transplant teams. By June 2014, six hundred eight foreign nationality kidney transplants were authorized by Ministry of Health for citizens for 17 countries. In this review, we examine the negative aspects of transplant for foreign citizens in Iran and the reasons that changed "travel for transplant" to "transplant tourism " in our country and finally led us to stop the program after more than 10 years.

Context: Alzheimer disease (AD) is the most common cause of dementia. In regards to the world’s aging population, control and treatment of AD will be one of the major concerns of global public health in the next century. Alzheimer disease was not mentioned with the same phrase or its equivalent in traditional medical texts. The main of present paper was to investigate symptoms and causes of alzheimer disease from the view point of Iranian traditional medicine. Evidence Acquisition: In this qualitative study, we searched reliable sources of Iranian traditional medicine such as Canon of Medicide by Avicenna (Al-Quanon fi- tibb), Aghili cure by Aghili’s (Molajat-E-aghili), Tib-E-Akbari, Exire -E-Aazam and Sharh-E-Asbab and some reliable resources of neurology were probed base on keywords to find a disease that had the most overlap in terms of symptoms with alzheimer disease. By taking from the relevant materials, the extracted texts were compared and analyzed. Results: Findings showed that alzheimer disease has the most overlap with Nesyan (fisad-e-zekr, fisad-e-fekr and fisad-e-takhayol) symptoms in Iranian traditional medicine. Although this is not a perfect overlap and there are causes, including coldness and dryness of the brain or coldness and wetness that could also lead to alzheimer disease according to Iranian traditional medicine. Conclusions: According to Iranian traditional medicine, The brain dystemperement is considered the main causes of alzheimer disease. By correcting the brain dystemperement, alzheimer can be well managed. This study helps to suggest a better strategy for preventing and treating alzheimer in the future. PMID:27247784

The dog mtDNA diversity picture from wide geographical sampling but from a small number of individuals per region or breed, displayed little geographical correlation and high degree of haplotype sharing between very distant breeds. For a clear picture, we extensively surveyed Iranian native dogs (n = 305) in comparison with published European (n = 443) and Southwest Asian (n = 195) dogs. Twelve haplotypes related to haplogroups A, B and C were shared by Iranian, European, Southwest Asian and East Asian dogs. In Iran, haplotype and nucleotide diversities were highest in east, southeast and northwest populations while western population had the least. Sarabi and Saluki dog populations can be assigned into haplogroups A, B, C and D; Qahderijani and Kurdi to haplogroups A, B and C, Torkaman to haplogroups A, B and D while Sangsari and Fendo into haplogroups A and B, respectively. Evaluation of population differentiation using pairwise FST generally revealed no clear population structure in most Iranian dog populations. The genetic signal of a recent demographic expansion was detected in East and Southeast populations. Further, in accordance with previous studies on dog-wolf hybridization for haplogroup d2 origin, the highest number of d2 haplotypes in Iranian dog as compared to other areas of Mediterranean basin suggests Iran as the probable center of its origin. Historical evidence showed that Silk Road linked Iran to countries in South East Asia and other parts of the world, which might have probably influenced effective gene flow within Iran and these regions. The medium nucleotide diversity observed in Iranian dog calls for utilization of appropriate management techniques in increasing effective population size.

Background: Failed visualization of the fetal nasal bone (NB) by ultrasound at 11 - 14 weeks of gestation is strongly associated with chromosomal abnormalities. Meanwhile, the incidence of the absent fetal NB in normal fetuses in the first trimester in mothers of different ethnic origins differs significantly. It is, therefore, important to assess ethnic variations in the first-trimester visualization of the fetal NB before introducing this marker into routine screening programs for aneuploidy. Objectives: The objectives of this study were to determine the NB length and the prevalence of the NB absence as well as calculating the likelihood ratio (LR) for the absence of the NB in normal fetuses of Iranian women undergoing first-trimester screening for trisomy 21. Patients and Methods: In 767 normal fetuses, the fetal profile was examined by ultrasound for the absence/presence of the NB. The NB length was also measured, and the LR for the NB absence was also determined. Results: The NB was absent in 2/767 (0.26%) of the fetuses. The mean length of the NB was 3.6 ± 0.69 mm for the fetuses of 11 - 14 weeks gestational age. The LR value of the absent NB was equal to 250 in the normal fetuses of the Iranian population living in the North-West provinces. Conclusion: The low prevalence of the NB absence in normal fetuses in the present study is compatible with the larger size of the NB in Iranian people compared to other communities. Meanwhile, the reference range of the NB length in normal Iranian fetuses was established so that basic data could be recorded for further studies regarding the absence or presence of the NB in screening for chromosomal abnormalities (Down syndrome) within the Iranian population.

The 32-base pair deletion on the C-C chemokine receptor 5 gene (CCR5-delta 32) is known as a protective allele against immune system disorders. We have studied this variation in Iranian multiple sclerosis (MS) patients and healthy controls. DNA samples were prepared from the whole blood of 254 patients with MS and 380 healthy controls. We amplified the fragment including the CCR5-delta 32 polymorphism and visualized the products in a documentation system after agarose gel electrophoresis. Data were analysed using one-way ANOVA and Fisher's exact tests with SPSS-v13 and STATA-v8 software. The delta 32 allele was more frequent in MS patients when compared with controls (OR = 2.3, P < 0.0001). Also, we found a significant difference in the frequency of the delta 32/delta 32 genotype among patients and controls (OR = 7.4, P < 0.001). The mean age at onset and progression index was not significantly different between patients with various genotypes. According to our study, the delta 32 allele of the CCR5 gene might be a predisposing factor for MS development in the Iranian population. However, there were no associations between this polymorphism and the clinical course of the disease in this study.

In Iran, along the northern and eastern fringes of the Pasargadae plain, five dam remains from the Achaemenid period (550-330 BCE) present an important footprint of the human impact and reshaping of the region. The dams are predominantly found in dry wadi beds. In the framework of the Joint Iranian-French Archaeological Project at Pasargadae, these dam sites were studied and excavated. Located 22 km to the north of Pasargadae in a small wadi, the Sad-i Didegan dam has a watershed of circa 46 square km, small compared with catchments of other known Achaemenid dams. It is an earth built gravity dam of circa 90 m wide, 21 m high and with a crown length of about 150 m. In the lower body of the dam, remains of a feeder canal and an accessible control infrastructure at the downstream flank of the dam were found. To the northwest, the dam site of Sad-i Shahidabad can be found, another large Achaemenid dam, which stored water from the perennial river of the Rud-i Polvar. This dam also had a similar canal and control structure. Close to the Sad-i Didegan area is a large earthwork, found to cross the watershed divide between Didegan and Shahidabad, consisting of a wide V-shaped trench of remarkable size: up to 100 m wide, a total length of at least 900 m and a maximum present day depth of 7.5 m. Even though the construction of the system in this case clearly was left unfinished, the remains echo the major investment of available labor. Given the contemporaneity of both dam sites, it is clear evidence of the more regionally and elaborately planned character of the hydrological endeavors in the Pasargadae area. Only through further study and future fieldwork (also obtaining absolute dating material), this impressive feature will be fully understood. This contribution proposes a possible use of the two dam system using a modern control simulation model. This analysis will also shed light on the question why the system probably never functioned.

Background: Obesity is a global epidemic and its morbidities such as metabolic syndrome, insulin resistance, and fatty liver leads to a spectrum of psycho-social and medical consequences. Objectives: The objective of this study was to investigate the prevalence of fatty liver in obese Iranian children and its' association with metabolic syndrome and insulin resistance. Patients and Methods: 102 obese Iranian children, referred to pediatric clinics from March 2011 to March 2012, were enrolled in this cross-sectional study. All the patients were visited by a pediatric endocrinologist, a pediatric gastroenterologist and an expert radiologist in the evaluation of fatty liver grading. Results: The grade of fatty liver was higher in older children (P = 0.001). It was also more in taller and heavier children (P = 0.000). The more the BMI was, the more the fatty liver grade was (P = 0.002). Severity of fatty liver according to liver sonography in patient had a positive relationship with waist circumference, hip circumference, serum TG, serum FBS, serum fasting insulin, serum ALT, systolic blood pressure and HOMA index and had a negative correlation with the level of alkaline phosphatase. Severity of fatty liver also had a close relationship with the presence of acanthosis nigricans and HOMA index. Conclusions: Prevalence of fatty liver is high in our obese children. It was associated with criteria of metabolic syndrome and insulin resistance, so visceral fat may participate in the pathogenesis of the metabolic syndrome or merely serve as a marker of increased risk for the metabolic complications of obesity.

PURPOSE Next Generation Sequencing (NGS) is currently used to establish mutational profiles in many multigene diseases such as colorectal cancer (CRC), which is on the rise in many parts of the developing World including, Iran. Little is known about its genetic hallmarks in these populations. AIM To identify variants in 15 CRC-associated genes in patients of Iranian descent. RESULTS There were 51 validated variants distributed on 12 genes: 22% MSH3 (n = 11/51), 10% MSH6 (n = 5/51), 8% AMER1 (n = 4/51), 20% APC (n = 10/51), 2% BRAF (n = 1/51), 2% KRAS (n = 1/51), 12% PIK3CA (n = 6/51), 8% TGFβR2A (n = 4/51), 2% SMAD4 (n = 1/51), 4% SOX9 (n = 2/51), 6% TCF7L2 (n = 3/51), and 6% TP53 (n = 3/51). Most known and distinct variants were in mismatch repair genes (MMR, 32%) and APC (20%). Among oncogenes, PIK3CA was the top target (12%). MATERIALS AND METHODS CRC specimens from 63 Shirazi patients were used to establish the variant' profile on an Ion Torrent platform by targeted exome sequencing. To rule-out technical artifacts, the variants were validated in 13 of these samples using an Illumina NGS platform. Validated variants were annotated and compared to variants from publically available databases. An in-silico functional analysis was performed. MSI status of the analyzed samples was established. CONCLUSION These results illustrate for the first time CRC mutational profile in Iranian patients. MSH3, MSH6, APC and PIK3CA genes seem to play a bigger role in the path to cancer in this population. These findings will potentially lead to informed genetic diagnosis protocol and targeted therapeutic strategies. PMID:28002797

The present study aimed at Investigating the knowledge and attitude of Nursing Students towards Iranian Traditional Medicine in universities of Tehran in 2012-2013. 300 students of nursing studying at different universities in Tehran participated in this descriptive, cross-sectional study. The data was collected through a standard questionnaire with an acceptable validity and reliability. The questionnaire was made of five sections including demographic, general knowledge of the Iranian traditional medicine, general attitude towards it, resources of the Iranian traditional medicine and the barriers to it. The results revealed that general knowledge of the students about Iranian traditional medicine and complementary medicine is low. The attitude of the students towards including Iranian traditional medicine and complementary medicine in their curriculum is positive. General attitude of students towards Iranian traditional medicine is positive too. The majority of the participants had not passed any course on Iranian traditional medicine. There was no relationship between participants’ attitude towards Iranian traditional medicine and the number of semesters they had passed. Considering the participants’ positive attitude and their low level of knowledge, it seems necessary for the university policy makers to provide nursing students with different training courses on Iranian traditional medicine and complementary medicine in order to increase their knowledge.

Change in today's healthcare settings is inevitable. Professional growth and development are essential in order to remain a viable member of the healthcare team. Although the importance of professional growth and development is emphasized in the literature, the associated outcomes of professional development have not been fully described. In this article the authors present a qualitative study in which 21 Iranian nurses, whose years of nursing experienced ranged from 3 to 28 years, shared the perceptions of their professional development and growth. In reporting the study findings the authors discuss how these nurses described their skill and psychosocial development within the themes of developing judgment, improving communication, instilling confidence, seeing the whole patient, and strengthening commitment to nursing.
Background: Empathy is an important element of physician-patient communication. Empathy is linked to a number of attributes such as patient treatment compliance and satisfaction, better history taking and physical examination and therefore achieving better clinical outcomes. Previous research indicates that self-reported empathy among medical students declines during the course of their medical education and this decrease in empathy particularly happens when students enter clinical training. Very limited data is available on the concept of empathy among Iranian medical students. The aim of the present study was to investigate empathy among Iranian medical students and the possible differences between students of different levels of medical education. Methods: The data were collected using convenient sampling. The Jefferson Questionnaire of Physicians Empathy-student version as well as a demographic questionnaire was distributed among 500 medical students in different levels of medical education at medical school of Iran University of Medical Sciences. Results: Response rate was 91.8% (459/500). Of 459 responders, 150 were first and second year students (Basic sciences), 170 were third to fifth year students (trainees) and 139 sixth and seventh year students (Interns). Sixty nine percent (n=318) were female and 31% (n=141) male. The mean score (SD) of empathy was 101 (15.6). The difference between mean score of empathy of female and male medical students was not significant (101.8 in females vs. 100 in males). The mean score of empathy in "interns" was significantly lower than both "trainees" and "basic sciences students" (96.2, 102 and 104, respectively p<0.05). Conclusion: The results of this study indicate that the empathy score of interns is significantly lower than other medical students. A longitudinal study is needed to test variations in students’ empathy throughout medical school. PMID:28210604

Introduction: The present study was conducted to assess the morphology of mandibular canines using cone-beam computed tomography (CBCT) in a north Iranian population. Methods and Materials: For the morphological assessment of mandibular canines, 150 CBCT images taken from patients for different reasons were used. The mandibular canines were examined in sagittal, coronal and axial dimensions. The canal pattern, number of roots/canals, the tooth length, the orientation of the roots and the position of the apical foramina were evaluated and the effect of gender on each variable was assessed. The obtained data were analyzed using the Chi-square and student’s t-tests. Results: According to the Vertucci’s criteria, the most common pattern was type I morphology (89.7%), followed by types III (5.7%), II (3.7%) and V (1%). No significant differences were observed between the male and female patients in terms of canal type (P>0.05). Gender difference is a factor which affected the root length and the number of mandibular canine root and root canal. There were 296 single-root and four double-root canines. The double-root canines and mandibular canine with two canals were significantly more common among men than women (P=0.00). The apical foramen was laterally positioned in 68.3% and centrally in 31.7% of the cases, and the root curvatures were mostly oriented toward the buccal region. No significant statistical difference was observed for mentioned parameters in right and left half of the jaw. Conclusion: Due the diverse morphology and the potential presence of a second mandibular canine among Iranians, dentists should perform endodontic treatments with greater care. CBCT is an accurate tool for the morphological assessment of root canals. PMID:28179930
Background and Aim. First-line treatment strategy for managing cervical disc herniation is conservative measures. In some cases, surgery is indicated either due to signs/symptoms of severe/progressive neurological deficits, or because of persistence of radicular pain despite 12 weeks of conservative treatment. Success for treatment of cervical disc herniation using ACDF has been successfully reported in the literature. We aim to determine the outcome of ACDF in treatment of cervical disc herniation among Iranians. Methods and Materials/Patients. In a retrospective cohort study, we evaluated 68 patients who had undergone ACDF for cervical disc herniation from March 2006 to March 2011. Outcome tools were as follows: (1) study-designed questionnaire that addressed residual and/or new complaints and subjective satisfaction with the operation; (2) recent (one week prior to the interview) postoperative VAS for neck and upper extremity radicular pain; (3) Japanese Orthopaedic Association Myelopathy Evaluation Questionnaire (JOACMEQ) (standard Persian version); and (4) follow-up cervical Magnetic Resonance Imaging (MRI) and lateral X-ray. Results. With mean follow-up time of 52.93 (months) ± 31.89 SD (range: 13–131 months), we had success rates with regard to ΔVAS for neck and radicular pain of 88.2% and 89.7%, respectively. Except QOL functional score of JOAMEQ, 100% success rate for the other 4 functional scores of JOAMEQ was achieved. Conclusion. ACDF is a successful surgical technique for the management of cervical disc herniation among Iranian population. PMID:27635392

Background Considering both diet and energy expenditures possess some influence on weight status, research into dietary determinants of obesity is challenging but essential to rational planning of well-organized interventions to avoid obesity. Objectives This study aimed to determine whether dietary factors were predictive of overweight and obesity in adolescents in the Iranian population. Patients and Methods A total of 840 students, ages 15 - 17, from six schools were enrolled in this cross-sectional study. A diet-patterns approach often has been used to describe the eating patterns in adolescents. Height, weight, and waist circumference anthropometric indices, physical activity, waist hip ratio, and BMI measurements were determined. Daily dietary data and weighed food records were collected in 2010 and 2011. Abdominal obesity was defined according to world health organization guidelines, and the relationship between dietary predictor variables and the measures of adiposity were determined by using linear regression. Usual dietary intakes were assessed in an experimental study of Esfahani students. Results In total, 38.5% of girls and 32.2% of boys had a Western dietary pattern as the more prevalent pattern. The diet quality of adolescents with the lowest score on each dietary pattern was compared with those recording the highest scores. Those with the Western dietary pattern score were less likely to exercise and had a higher prevalence of general obesity. Adolescents in the greater quartile of the Mediterranean dietary patterns had the lowest odds of being overweight (OR 0.50, 95%; CI 0.27 - 0.73) and obese (OR 0.48, 95%; CI 0.15 - 0.80) than those in the lower quartile, whereas those in the greater quartile of the Western dietary pattern had the highest odds of being overweight (OR 1.69, 95%; CI 1.10 - 2.04) and obese (OR 1.44, 95% CI 1.05 - 1.84). Higher consumption of a Western dietary pattern and a salty dietary pattern were associated significantly with

The stereotypical public image of nursing is a major concern for male nurses around the world. In this study, we explored how Iranian male nurses perceived the public view of nurses, and their perceptions of themselves. A qualitative descriptive design and content analysis were used to obtain data from 18 purposely-selected male hospital nurses with a baccalaureate nursing degree in Tabriz, Iran. Semistructured interviews were conducted and analyzed. Two main themes emerged: (i) the outsider's view of nursing, which referred to the participants' perceptions of their public image; and (ii) the insider's view, which related to the male nurses' perceptions of themselves. Results included personal transition into a positive professional self-image through the educational process, and continued public perception of nursing as a female profession ill-suited for a man. Strategies to improve the insider's and outsider's views of nursing are listed to help recruit and retain more Iranian male nurses.

Brain death is defined as the permanent, irreversible and concurrent loss of all brain and brain stem functions. Brain death diagnosis is based on clinical criteria and it is not routine to use paraclinical studies. In some countries, electroencephalogram (EEG) is performed in all patients for the determination of brain death while there is some skepticism in relying on EEG as a confirmatory test for brain death diagnosis. In this study, we assessed the validity of EEG and its abnormalities in brain death diagnosis. In this retrospective study, we used 153 EEGs from medical records of 89 brain death patients in organ procurement unit of the Iranian Tissue Bank admitted during 2002-2008. We extracted and analyzed information including EEGs, which were examined by a neurologist for waves, artifacts and EEG abnormalities. The mean age of the patients was 27.2±12.7 years. The most common cause of brain death was multiple traumas due to accident (65%). The most prevalent artifact was electrical transformer. 125 EEGs (82%) were isoelectric (ECS) and seven EEGs (5%) were depictive of some cerebral activity which upon repeat EEGs, they showed ECS patterns too. There was no relationship between cause of brain death and cerebral activity in EEGs of the patients. In this study, we could confirm ECS patterns in all brain death patients whose status had earlier been diagnosed clinically. Considering the results of this study, it seems sensible to perform EEG as a final confirmatory test as an assurance to the patients' families.

Objective Iran ranks 173 out of 180 countries on an index of press freedom. The purpose of the study was to assess the psychological wellbeing of Iranian journalists and document the stressors encountered in their work. Design A secure website was established and participants were given their unique identifying number and password to access the site. Setting Newsrooms in Iran and the diaspora. Participants Responses were received from 114 journalists (76%) of whom 65.8% were living in the diaspora. The mean age was 37.8 years (SD = 7.30) and 57% male. Main outcomes measures Type of stressor and behavioural data: Impact of Event Scale-revised for posttraumatic stress disorder, Beck Depression Inventory-II for depression. Results Stressors include arrest (41.2%), torture (19.3%), assault (10.5%), intimidation (51.4%) and family threatened (43.1%). Eighty nine (78.1%) journalists had stopped working on a story because of intimidation. Arrest, torture, intimidation and family threatened were associated with more intrusive and arousal PTSD symptoms (p < .01 to .001) and assault and intimidation with more depressive symptoms (p < .05). Almost a third of Iranian journalists regularly used barbiturates, with use correlating with symptoms of intrusion (p < .0001), avoidance (p < .01), arousal (p < .0001) and depression (p < .0001). 46.5% of Iranian journalists were not receiving therapy for their distress. Conclusions The findings, the first of their kind, provide data highlighting the extraordinary degree of danger confronted by Iranian journalists, their emotional distress in response to this and their proclivity to self-medicate with barbiturates.

Context: Functional dyspepsia (FD) is a functional gastro-intestinal disorder with high prevalence. Among various treatment options, treatment by complementary and alternative medicines especially herbal remedies also practiced. Traditional Iranian medicine (TIM), a valuable resource of valid applied studies of ancient Iranian scholars, recommends numerous medicinal plants to treat dyspepsia symptoms. In this study, through investigation of TIM references, we aimed to identify medicinal plants for treatment of digestion insufficiency. Evidence Acquisition: In this qualitative study, dyspepsia symptoms including fullness, early satiety, bloating, nausea, and belching were checked under reliable sources of traditional medicine. Then medicinal plants recommended for the treatment of the symptoms were extracted from the books. Likewise, for investigating the pharmacological properties of medicinal plants used for the relieving of dyspepsia symptoms, electronic databases such as PubMed, Scopus, Google Scholar and some Iranian databases like SID and IranMedex were employed. Results: The study yielded 105 plants from 37 families which could treat various dyspepsia symptoms; fifty-seven plants, mainly from Apiaceae, Lamiaceae, Amaryllidaceae and Zingiberaceae had digestive effects. In this research, based on the information in TIM reference texts, we obtained 58 plants effective for bloating, 40 for nausea, 37 for appetite loss and 7 for belching. In human clinical trials conducted on medicinal plants effective for FD symptoms, 7 single plants were used. Conclusions: Finding the medicinal plants effective on digestion insufficiency based on TIM could suggest a better strategy for the relieving of dyspepsia symptoms. Traditional Iranian medicine prescribes medicinal plants based on each patient’s personal characteristics and practices multiple target therapies. PMID:26734483

Background: Migraine is a common neurovascular disorder with multifactorial and polygenic inheritance. The aim of this study was to investigate the association of a migraine without aura and Ala379Val polymorphism of lipoprotein-associated phospholipase A2 (Lp-PLA2) gene in the Iranian population. Methods: In this study, 103 migraine patients and 100 healthy controls were enrolled. DNA samples were extracted and the Ala379Val polymorphism of Lp-PLA2 gene was investigated. To assess severity of a headache, patients filled out the headache impact test (HIT-6) and migraine severity (MIGSEV) questionnaires. Results: Allele V had significantly lower frequency in the case group than control subjects [P = 0.001, odds ratio (OR) = 0.25, confidence interval (CI): 0.15-0.40]. The frequency of migraine patients that were a carrier of V allele (V/V and A/V) was statistically significant lower than the control group (P = 0.003, OR = 2.39, CI: 1.35-4.23). There was no significant difference of alleles frequency between three grades of MIGSEV (P = 0.316). Furthermore, total HIT-6 score was not significantly different between different genotypes (P = 0.466). Conclusion: Our results showed that Ala379Val gene polymorphism of LP-PLA2 is associated with lower risk of migraine but not with severity of headaches in an Iranian population. PMID:27326362

Catarrh is a condition that is carefully explained in Iranian traditional medicine. Medieval Iranian physicians used some medicinal plants in the treatment of the catarrh. Some of these substances are used in treatment today, although still more of these materials can be used in modern medicine. In this study we searched known sources of Iranian traditional medicine and collected the ideas of former great scholars and physicians about medicinal plants that are used for treatment of catarrh. Then we searched PubMed, Google Scholar, Scopus, and Web of Science databases and found 10 medicinal herbs that have the ability to treat catarrh. Plants discussed in this study are consistent with new research and can be used in modern treatments. According to rising bacterial resistance to antibiotics and complications of antibiotic and anti-inflammatory drugs, it seems that the various components of the medicinal herbs can be beneficial in producing new drugs. Also it is hoped that more investigations on medicinal plants will be conducted in the future treatment of catarrh and other diseases related to it. PMID:26151014
Background: There is increasing evidence that children are showing body image issues in recent years. Body image disturbances in childhood must be taken seriously. The thin ideal is becoming more prominent in Asian countries; however, there is little research examining how this issue affects Iranian children. This study explores body weight concerns and associated factors among children in Iranian elementary schools. Methods: This study was conducted in 500 elementary schools. An assessment of body image and antifat attitudes was undertaken using the figure rating scale. In addition, body mass index (BMI) and demographic variables were assessed. Results: Nearly, 27.4% of children were underweight, and 13.3% were obese. There was a significant difference between the mean score of body dissatisfaction (BD) between boys and girls (P < 0.05). There were no differences between BD and education of parents, age, and academic grades. In girls, antifat attitudes were significantly related to BMI. Conclusions: The results of this study demonstrate the paramount importance of undertaking further research in order to identify the predictive factors of body concerns and its consequences among Iranian children. In addition, researchers must plan prevention and educational program for these children. PMID:25709795

Context: Headache is a common symptom throughout the world. The main purpose of patient-centered approaches is the utilization of useful and simple treatment. Nowadays, there is a rising propensity toward herbal remedies. Nasal route is one of the ancient and topical prescriptions used in headache. In Iranian traditional medicine, physicians such as Avicenna were prescribing herbal drugs through the nose to treat a variety of central nervous system diseases like headache. In this review paper, authors have attempted to introduce different types of nasal administrations which were used in Iranian traditional medicine for the treatment of headaches. Evidence Acquisition: Initially, we studied two different types of Canon and separated all herbs used in the treatment of headache. Next, all plants were classified according to the method of prescription. Then, we pick out all the plants which were nasally utilized in the treatment of headache and divided them based on the method of administration. In order to find scientific names of herbs, we used two different botany references. Moreover, we conducted various researches in scientific databases with the aim of finding results concerning the analgesic and antinociceptive effects of herbs. Throughout the research, key terms were “analgesic” and “antinociceptive “with the scientific names of all herbs separately. The databases searched included PubMed, Scopus, Cochrane library and SID. Results: 35 plants were prescribed for the treatment of headaches, which were all nasally used. These plants took either the form of powder, liquid or gas (steam). They were divided in to six categories according to the method of prescription. The Percentage of usage for each method was as follows: 62% Saoot (nasal drop), 25% Shamoom (smell), 17% Inkabab (vapor), 11% Nafookh (snuff), 11% Nashooq (inhaling) and 2% Bokhoor (smoke). Conclusions: Medications that are used via nasal delivery have greater effect than oral medications

Introduction: Quoting an article in well-known textbooks is held as a credit for that paper. The numbers of Iranian publications mentioned in endodontic textbooks have increased during recent years. The aim of this investigation was to evaluate the number of Iranian articles quoted in eminent endodontic textbooks. Methods and Materials: Three known textbooks (Ingle’s Endodontics, Seltzer and Bender’s Dental Pulp and Cohen’s Pathways of the Pulp) were chosen and all the editions of the textbooks since 2000 were investigated for quoted Iranian publications. Only Iranian authors with affiliations from a domestic university were chosen. All references at the end of each chapter were read by hand searching, and results were noted. The trend and percentage of Iranian publications in different editions of the textbooks were also calculated. The number of citations of these publications in Google Scholar and Scopus databases were also obtained. Results: The number of Iranian publications in all well-known textbooks have notably increased since 2000. The number and percentage of Iranian publications in the latest edition of Cohen’s Pathways of the Pulp was higher compared to other textbooks as well as the previous edition of the same text. Conclusion: Number and percentage of Iranian publications in the field of endodontics in all three textbooks have remarkably increased since 2000. PMID:27471523

Background: Body weight is made up of lean and fat mass and both are involved in growth and development. Impression of these two components in bone density accrual has been controversial. Objectives: The aim of this study was to evaluate the relationship between fat and lean mass and bone density in Iranian children and adolescents. Patients and Methods: A cross-sectional study was performed on 472 subjects (235 girls, 237 boys) aged 9-18 years old in Fars Province. The participants' weight, height, waist circumference, stage of puberty, and level of physical activity were recorded. Bone Mineral Content (BMC), Bone Mineral Density (BMD), total body fat and lean mass were measured using dual-energy X-ray absorptiometry. Results: Results showed that 12.2% of boys and 12.3% of girls were overweight and 5.5% of boys and 4.7% of girls were obese. Obese individuals had greater total body BMD (0.96 ± 0.11) than normal-weight ones (0.86 ± 0.11) (P < 0.001). We found the greatest correlation between total body BMD and total body lean mass (R = 0.78. P < 0.001) and the least correlation with total body fat percentage (R = 0.03, P = 0.44). Total lean mass in more active boys was 38.1 ± 10.9 and in less active boys was 32.3 ± 11.0 (P < 0.001). The results of multiple regression analysis showed that age and total body lean mass were independent factors of BMD in growing children and adolescents. Conclusions: These findings suggest that lean mass was the most important predictor of BMD in both genders. Physical activity appears to positively impact on lean mass and needs to be considered in physical education and health-enhancing programs in Iranian school children. PMID:26401143

Background: Individuals with certain personality disorders, especially the antisocial and borderline personality disorders, are more prone to substance use disorders. Objectives: Regarding the importance of substance use disorders, this study aimed to explore the association between personality disorders and types of used drugs (narcotics and stimulants) in Iranian male substance users. Patients and Methods: The current study was a correlation study. We evaluated 285 male substance users and excluded 25 according to exclusion criteria. A total of 130 narcotic users and 130 stimulant users were recruited randomly in several phases from January 2013 to October 2013. All participants were referred to Substance Dependency Treatment Clinics in Tehran, Iran. Data collection process was accomplished by means of clinical interview based on DSM-V criteria for substance use disorders, Iranian version of addiction severity index (ASI), and Millon clinical multi-axial inventory-III (MCMI-III). Data were analyzed by SPSS 21 using Pearson correlation coefficient and regression, the. Results: There was a significant correlation between stimulant use and histrionic personality disorder (P < 0.001) and antisocial and narcissistic personality disorders (P < 0.05). In addition, correlation between avoidant, histrionic, and narcissistic personality disorders (P < 0.05) and depressed, antisocial, and borderline personality disorders (P < 0.001) with narcotics consumption were significant. In clusters, there was a significant correlation between cluster B personality disorders, and narcotic and stimulants consumption (P < 0.001). In addition, this association was explored between cluster C personality disorder and narcotics (P < 0.001). Conclusions: The results of this study in terms of personality disorders and types of used drugs were in accordance with the previous studies results. It is necessary to design appropriate treatment plans for medical treatment of those with personality

Background Clinical studies are giving increased importance to quality of life assessments as measures of the relative effectiveness of prevention and treatment programs used during pregnancy and antenatally. Objectives The aim of this study was to validate the Quality of life gravidarum (QOL-GRAV) questionnaire for Iranian women during the pregnant period Patients and Methods In this cross-sectional methodological study, content validity following back and forward translation was assessed by a panel of experts. Using the two-stage cluster sampling method, 565 pregnant women referred to health care centers from April to June 2015 in Tabriz, Iran were enrolled in the study. Construct validity by assessing the factor structure, and convergent and discriminant validity were evaluated using scale-item correlations and known group analyses. Internal consistency and test–retest reliability were assessed in a sample of 30 pregnant women by the Cronbach’s α coefficient and intra-class correlation coefficient (ICC). Results The QOL-GRAV showed good content validity (CVI value = 0.95 and CVR value = 1), internal consistency (α = 0.79), and test–retest reliability (ICC = 0.86). The results of the CFA for two-factor models indicate an acceptable ﬁt of the proposed model (RMSEA; 90% CI = 0.083; 0.068–0.099, CFI = 0.95, GFI = 0.96, and AGFI = 0.92). Conclusions The findings support the validity and reliability of the Iranian version of the QOL-GRAV questionnaire. Therefore, it is recommended to be used for both clinical and research purposes.

Background: Prerequisite for management of a chronic disease involves knowledge about its complications and their prevention. Hemophilia in adolescents influences all the aspects of their lives and thier performance. Objectives: The present study aimed to determine the performance of Iranian hemophilic adolescents in prevention of disease complications. Patients and Methods: In this descriptive-analytical study, 108 adolescents with hemophilia were selected through convenience sampling. Their performance in preventing the complications of hemophilia was evaluated by sending a semi-structured questionnaire to their addresses throughout Iran. Then, the data was analysed using the Statistical Package for Social Sciences (SPSS) software (v. 13) and descriptive and interferential statistics were used. Results: Overall, 32.1% of the participants controlled bleeding during the 1st hour. Inaccessibility of coagulation products was mainly responsible for inhibiting timely and proper bleeding control. In order to relieve bleeding associated pain, only 39.0% of the adolescents used analgesics. On the other hand, 19.8% of the subjects used nonpharmacological methods to relieve pain. The majority of the adolescents did not participate in sport activities (65.4%) others allocated less than 5 hours a week to physical activities (70.5%). In addition, the participants did not have favorable dietary patterns, exercise habits, and dental care. The results showed a significant relationship between the adolescents’ preventive practice with coagulation disorders and utilization of pharmacological pain relief methods. Also, significant relationships were found between severity of the disease; participating in physical activities, number of hours of physical activities; and disease complications. Conclusions: Iranian adolescents did not exhibit favorable practices towards complication prevention. PMID:26600702

This study examined the relationship between three mental health constructs and perceived cultural attitudes toward homosexuality among lesbian, gay, and bisexual individuals. Specifically, differences in perceived cultural attitudes and depression, self-esteem, and perceived stress between 49 Iranians and 47 Americans were compared. It was hypothesized that (a) perceived cultural attitudes toward homosexuality would be more negative among Iranians than Americans; (b) perceived cultural attitudes would be related to depression, self-esteem, and perceived stress; and (c) that Iranian participants' scores on the depression, self-esteem, and perceived stress measures would reflect poorer mental health than that of their American counterparts. Results indicated more negative perceptions of cultural attitudes toward homosexuality among Iranians. Contrary to prediction, however, no difference was found in levels of depression, self-esteem, and perceived stress among American and Iranian participants. Findings are discussed in terms of cultural and familial differences with regard to sexual orientation disclosure.

Background: Type 2 diabetes mellitus (T2DM) is a worldwide problem that threatens the public health and economies of all countries. A multifactorial etiology and interaction between environmental factors and genetic components are responsible for triggering and progression of T2DM. Recently, rs7754840 single nucleotide polymorphism (SNP) in the CDKAL1 gene was reported to be associated with T2DM in various populations. However, due to inconsistent results in various populations about the association of rs7754840 with T2DM, and lack of information in the Iranian population, we have evaluated its association with T2DM in a subset of the Iranian population from Isfahan province, central part of Iran. Materials and Methods: The study included 140 patients and 140 controls selected based on the World Health Organization guidelines. Genomic DNA was extracted from blood samples and the rs7754840 SNP was genotyped using a polymerase chain reaction-restriction fragment length polymorphism assay with specific primers and restriction enzyme (Ac1I). Results: The frequency of the C allele in the cases was higher than that in the controls (72.9% vs. 65%; P = 0.045). Using logistic regression analysis, we found a significant risk association of CC genotype with T2DM susceptibility (OR = 2.319, 95% CI = 1.436-3.744, P = 0.001). Furthermore, compared with the CC genotype, individuals with the GC genotype had a lower risk (protective association) of developing T2DM (OR = 0.332, 95% CI = 0.202-0.547, P < 0.001). Conclusions: We confirmed that there is a significant risk association between rs7754840 polymorphism and development of T2DM in a subset of the Iranian population from Isfahan province.

Background Endometriosis is a chronic gynecological disease resulting from complex interactions between genetic, hormonal, environmental and oxidative stress and intrinsic inflammatory components. The aim of this study was to investigate the potential association of the 763C>G polymorphism in the secretory phospholipase A2 group IIa gene (PLA2G2A) with the risk of endometriosis in Iranian women. Materials and Methods Ninety seven patients with endometriosis along with 107 women who were negative for endometriosis after laparoscopy and laparatomy, and served as the control group, were enrolled for this cross-sectional study. Samples were genotyped using the polymerase chain reaction-restriction fragment length polymorphism method. Results Multivariate analysis was used to examine the association between the risk of endometriosis and the 763C>G polymorphism of PLA2G2A. Genotype distributions of PLA2G2A were significantly different between patients and the controls (p<0.001, OR=0.22, 95% CI=0.21-0.39). Correlation analysis showed that there was a significant association between the normal homozygous genotype and susceptibility to endometriosis (p<0.001). Conclusion The present study suggests that the 763C>G polymorphism of PLA2G2A plays an important role as an independent factor in the risk of endometriosis in Iranian women. PMID:25780526

Spiritual care is an essential component in nursing practice and strongly influenced by the sociocultural context. This article aimed to elucidate the meaning of nurses' experiences of giving spiritual care in southeast of Iran. A phenomenological hermeneutic approach influenced by Ricoeur was used. Eleven staff nurses who were currently working in the 3 major hospitals under the umbrella of the Kerman University of Medical Sciences were interviewed. The meaning of spiritual care was comprehensively understood as meeting patient as a unique being. This can be divided into 3 themes: meeting patient as a being in relationship, meeting patient as a cultural being, and meeting patient as a religious being. The results in this study suggest that education about spirituality and spiritual care should be included in the continuous and in-service education of registered nurses. Spiritual and cultural assessment criteria should be included in this education to improve the provision of holistic care.

Inflammation and dysregulated lipid metabolism are involved in the pathogenesis of preeclampsia, and fatty acid binding protein 4 (FABP4) is known to regulate both inflammation and lipid metabolism. In the present study, we elucidated the role of FABP4 using in vitro and in vivo models of preclampsia. We found increased expression of FABP4 in the placenta of preeclamptic rats, which was further confirmed in HTR-8 cells, an extravillous trophoblast cell line, treated with L-NAME. Overexpression of FABP4 in HTR-8 cells resulted in upregulated expression of pro-inflammatory cytokines IL-6 and TNF-α, and increased lipid accumulation, suggesting that FABP4 plays a role in preeclampsia. Furthermore, downregulation of methylation in the promotor resulted in increased FABP4 expression, which was mediated by downregulated DNA methyltransferase 1 (DNMT1). Bioinformatics analysis showed that miR-148a/152 regulated the expression of DNMT1, and additional in vitro studies revealed that miR-148a/152 inhibited DNMT1 expression by directly binding to its 3'-UTR. Interestingly, DNMT1 enhanced the expression of miR-148a/152 by downregulation of methylation in its promotor. Taken together, our results showed that FABP4 may be involved in the pathogenesis of preeclampsia, and the expression of FABP4 is enhanced by miR-148a/152 mediated inhibition of DNMT1 expression.
Quantum organizations are referred where stakeholders know how to access the infinite potential of the quantum field. Viewing healthcare organizations from perspective of quantum theory suggest new approaches into management techniques for effective and efficient delivery of healthcare services. This research is aimed to determine the quantum skills, quantum leadership characteristics and functions of Tehran University of Medical Sciences hospitals' nursing administrators. A cross-sectional, descriptive and analytical study was conducted among 25 nursing administrators of Tehran University of Medical Sciences (TUMS) hospitals, Tehran, Iran. The research tool for data collection was a self-constructed questionnaire that measured the quantum skills, quantum leadership characteristics and functions of TUMS hospitals' nursing administrators. The validity of questionnaire was confirmed by 5 management science experts and its reliability was performed by using test-retest method yielded a Cronbach's alpha coefficient of 0.90. Data were collected and analyzed by SPSS software and t-test statistical methods. The results of this research showed that all respondents had desired quantum skills (75.71±5.98), quantum leadership characteristics (82.01±6.77), and quantum leadership functions (78.57±6.28) and total quantum leadership (78.76±4.50). Also, passing management training courses of the respondents was significantly correlated with their quantum leadership. Iranian healthcare organizations require quantum leadership that provides an important resource to advance Iranian nursing leadership to the organizational excellence. We hope Iranian hospitals' nursing leaders who have quantum skills potentially, present a highly developed sense of self and the ability to improve nursing care outcomes in these hospitals.

Background: Leucorrhea or vaginal discharge is a conventional complaint. It is generally whitish, yellowish, or greenish vaginal discharge in females that might be normal or a symptom of infection. It is almost mucus discharge, which exhibit exfoliation of vaginal epithelial cells due to estrogen influence on the vaginal mucosa. It is important to identify the differences between physiologic and pathologic discharges. Leucorrhea is a well-known disease in Iranian traditional medicine (ITM). In their manuscripts, the word “Sayalan-e rahem” was used by Avicenna and some other Iranian traditional practitioners to describe this condition. Ancient practitioners believed that excessive residue (kesrate fozool) and weakness of digestion (Za’afe hazm) were the main causes of leucorrhea, for which herbal therapy was the main proposed treatment. In the present study, medicinal plants used in ITM for leucorrhea are introduced. Methods: In this research, six Iranian traditional textbooks including Canon of Medicine (Avicena 980-1037 AD), A-Hawi (Razes 865-925 AD), Tuhfat ul-Momineen (Mo’men tonekaboni, 17th century), Makhzan-ul-Adwiah (Aghili 18th century), Ikhtiarat Badi’i (Ansari 1329-1404 AD), and al-jāmi li-mufradāt al-adwiyawa al-aghdhiy (Ibn al-Baitar 1197 AD) were studied and searched for anti-leucorrhea medicines. Then the herbal medicines were selected and scored depending on their frequency in the above-mentioned textbooks. Additional attention was paid to provide the most suitable scientific name for each plant. Results: This study introduced many Materia Medica with anti-leucorrhea activity and among them seven herbs including Rubus fruticosus L., Rhus coriaria L., Phoenix dactylifera L., Pimpinella anisum L., Rumex acetosa L., Olea europaea L. and Quercus lusitanica Lam. showed the most repetition in ITM prescriptions. Conclusion: These herbs can be introduced as new anti-leucorrhea herbal medicines for clinical research. PMID:27516669

Iranian Plateau reflects several different tectonic styles of collision, and large-scale strike-slip faults. We calculate a high-resolution 2-D ML shear velocity map for the Iranian Plateau to detect lateral crustal thickness changes associated with different tectonic boundaries. The ML velocity is very sensitive to strong lateral variations of crustal thickness and varies between the velocity of Lg and Sn phases. Our data set consists of 65 795 ML amplitude velocity measurements from 2531 precisely relocated events recorded by Iranian networks in the period 1996-2014. Using a constrained least-squares inversion scheme, we inverted the ML velocities for a 2-D shear velocity map of Iran. Our results show that the Zagros and South Caspian Basin (SCB) have shear wave velocities close to the Sn phase, and are thus Lg-blocking regions. High velocities in the High Zagros and the Simply Folded Belt imply significant crustal undulations within these zones. We note that in the central and south Zagros, the velocity border between the Zagros and central Iran is not coincident with the Zagros suture line that marks underthrusting of the Arabian plate beneath central Iran. The low plains of Gilan and Gorgan to the south of the Caspian Sea show high shear velocities similar to the SCB, implying that they are either underlain by an oceanic type crust or a transitional crust with a strong lateral crustal thickness gradient. The Lut block is an Lg-passing block implying that it is not surrounded by any sudden crustal thickness changes along its borders with central Iran. In the Alborz, NW Iran, Kopeh-Dagh, Binalud and most of the central Iran, low shear velocity near the Lg velocity is attributed to smooth or minor Moho undulations within these regions.

Iranian women have shown improving contribution in the field of physics as students and researchers in recent years. More than 60% of BSc and MSc students, 47% of PhD students, and 18% of faculty members in the physics departments in Iran are female. However, in higher levels of academic fields and management, participation by women is still below the expected values. The Women in Physics branch of the Physics Society of Iran studies the related cases to find suitable strategies to improve the situation.

Background: Correlation between chronological age at different stages of cervical vertebral maturation (CVM) is important in clinical orthodontic practice. The objective of this study was to evaluate the correlation between CVM stage and chronological age in a group of Iranian female patients. Materials and Methods: This study was conducted on 196 digital lateral cephalometry of female patients with the age ranged 9-14 years. The CVM stage was determined with two calibrated examiners, using the method developed by Baccetti and its correlation with mean chronological age was assessed by the Spearman rank-order. The intra and inter-agreements were evaluated by weighted Kappa statistics in overall diagnosis of stages, in addition to determination of presence or absent of concavities at the lower border of second, third and fourth cervical vertebrae and the shapes of the third and fourth vertebrae. P < 0.05 was considered as significant. Results: The correlation coefficient between CVM stages and chronological age was relatively low (r = 0.62). The least amount of inter-observer agreement was determined to be at the clinical decision of the shape of the fourth vertebra. Conclusion: Regarding the low reported correlation, the concomitant usage of other skeletal indicators seems necessary for precise determination of physiological age of the patients. PMID:26604958

Background: The development of allergic rhinitis (AR) is caused by the interaction between genetic predisposition and environmental factors. In this study, the association between GATA3 single nucleotide polymorphisms and AR in an Iranian population was identified. Methods: This case-control study was performed on 86 patients with AR and 86 healthy subjects. This study aimed to evaluate a potential association between two GATA3 SNPs, rs1269486 and rs2229360, and AR. Blood samples were collected and DNA was extracted for the evaluation of these SNPs by RFLP-PCR. Results: A statistically-significant association was found between rs1269486 and AR (P<0.001). The frequencies of the A and GA genotypes were less in patients than in controls. The frequencies of the G allele and the GG genotype were greater in patients than in controls (P < 0.001). Conclusions: SNP rs1269486 of GATA3 was associated with AR and sensitivity to aeroallergens in our population. Because of the significance of this gene in AR, studying the association between GATA3 polymorphisms and AR is recommended for other populations. PMID:28367470

Patients with mental illness require unique and specific care. The purpose of this study was to explore the experiences of nurses, who provide such care for mentally ill people, within the context of Iranian culture. This hermeneutic phenomenological study was carried out in a university-affiliated hospital in an urban area of Iran. We interviewed 10 mental health nurses to capture in detail their experiences in psychiatric units, and the approach developed by Diekelmann et al. was employed to analyse the data. Four themes and five sub-themes were identified: 'being engaged with patients' (sub-themes: 'struggle for monitor/control', 'safety/security concerns', 'supporting physiological and emotional needs'), 'being competent', 'altruistic care' and 'facing difficulties and challenges' (sub-themes: 'socio-cultural' and 'organizational challenges'). The results provide valuable insights and greater understanding of the professional experiences of psychiatric nurses in Iran, and indicate the need for a stable and responsible organizational structure for those nurses who are expected to manage patient care in psychiatric wards.

Background: Living with patients of chronic diseases such as heart failure (HF) is a difficult situation for the caregivers. This study explored the Iranian family caregivers’ burden of caregiving for patients with HF. Materials and Methods: Eighteen family caregivers of the HF patients from two governmental medical training centers in Isfahan, Iran were recruited using purposive sampling. Data were collected through face-to-face semi-structured interviews. Each interview was transcribed verbatim and was thematically analyzed concurrently. Results: Four major themes emerged from the analysis of the transcripts: Lack of care-related knowledge, physical exhaustion, psychosocial exhaustion, and lack of support. Family caregivers believed that they have little knowledge about the patients’ disease, drugs, and how to perform caregiving roles. They experienced negative physical and psychosocial consequences of full-time and highly extended caregiving roles, such as musculoskeletal disorder, fatigue, and sleep disturbance, and a high level of anxiety, stress, and social isolation. Caregivers believed that they receive little familial and organizational support on the emotional and financial dimensions of caregiving. Conclusions: The findings of this study can be used by healthcare providers, especially nurses, to provide more effective social, informational, and professional support for family caregivers.

Discovery and analysis of care meanings, expressions, and practices of Iranian Immigrants in New South Wales, Australia was the focus of this ethnonursing qualitative research. The purpose of the study was to systematically discover, describe and analyse the values, beliefs, and practices of Iranian immigrants in New South Wales, Australia. The aim of the investigation was to discover transcultural nursing knowledge to guide nurses and health professionals to provide culturally congruent nursing and health care to Iranians. Leininger's theory of Culture Care Diversity and Universality (Leininger, 1991) was used as the conceptual framework for the study. It was predicted that care meanings and expressions of Iranian immigrants would be influenced by their worldview, social structure features, language, and cultural values rooted in their long ethnohistorical past and reflected in their lifeways in Australia. Using the ethnonursing qualitative research method, key and general informants were purposefully selected among Iranian immigrants residing in New South Wales. Three care themes supported by a number of universal and some diverse patterns were identified for Iranian immigrants. The three themes were: (1) Care meant family and kinship ties (hambastegie) as expressed in daily lifeways and interactions with family, friends, and community; (2) Care as expressed in carrying out traditional urban gender roles (role-zan-o-mard) (Azadie zan) as well as in fulfilling emerging new role responsibilities related to equality for female Iranian immigrants; and (3) Care as preservation of Iranian identity (inhamoni, hamonandi) as expressed in traditional cultural events and health care practices. Leininger's (1991) three modes of actions and decisions were used to develop appropriate and culturally meaningful nursing care actions and decisions which were in harmony with the cultural beliefs of Iranian immigrants.

Introduction. Naegleria fowleri, a free living amoeba, can cause devastating and deadly diseases in humans. This is the first report of primary amoebic meningoencephalitis from Iran. Case report. A five-month-old male infant presented with the history of fever and eye gaze for three days, after beginning of bacterial meningitis, a plain and contrast CT revealed communicated hydrocephalus. In the repeat of CSF analysis on microscopic examination of wet preparation of CSF, Naegleria Fowleri was seen. Then, Amphotericin B and Rifampin were started. On followup, two months later, the patient was totally asymptomatic. Conclusion. Though occurrence of PAM is rare, this unusual disease has grave prognosis, so infection with free living amoebas must be considered in differential diagnosis of pediatric patients of purulent meningitis without evidence of bacteria on Gram's stain and imaging findings, nonspecific brain edema on CT or hydrocephalus even without history of contact.

Background: Thalassemia syndromes are the most prevalent single gene disorders in Iran. This study aimed to evaluate the effect of different types of beta-globin gene mutations, co-inheritance of alpha-globin gene mutations and/or Xmn1 SNP on disease phenotype in a large cohort of Iranian patients. Subjects and Methods: In total, 433 patients were clinically classified into β-thalassemia major (TM) or intermedia (TI). Multiplex PCR, ARMS-PCR, RFLP-PCR and DNA sequencing were performed to identify both α- and β-globin gene mutations and Xmn1 polymorphism as well. All data were compared and analyzed by SPSS software in TM and TI groups, consequently. Results: A total of 39 different β-globin mutations were identified. Among them, the most common were IVS IInt1 (40.33%) followed by IVS Int5 (9.56%), C30 (7.22%) and Fr8-9(7%). All patients were subjected to evaluate common α-globin gene deletions. The patients inherited concomitant mutations of α- and β-globin, showed no clinical modifications compared with those who had only β-globin mutation. The TI patients showed a significant increase in frequency of both heterozygous and homozygous form of the Xmn1 polymorphism. It was also found that β0/β0 genotype patients, inherited the Xmn1 polymorphism required lesser blood transfusion. Conclusion: No significant differences were observed, on the severity of disease, between patient's inherited defective α- and β-globin genes and ones with just β-globin gene mutation. Taking the results of this research into account, Xmn1 polymorphism can be considered as an important genetic factor modulating the severity of disease. PMID:26865931

Male breast cancer is a rare disease with an increasing trend. Due to limited information especially about the genetic basis of the disease in Iran and the lower age of its onset, the disease requires more attention. The aim of this study was to screen the male patients with breast cancer for BRCA mutations as well as tissue markers of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor (HER-2) and cytokeratin 5/6 (CK5/6). Ten Iranian males with breast cancer were selected regardless of their histologic subtypes, age and family history from patients referred to Mehrad, Day and Parsian hospitals in Tehran, Iran, during a two-year period. Paraffin blocks of the tumoral regions were tested for ER, PR, HER-2 and CK5/6 immunostaining. DNA extraction was carried out on the EDTA blood samples followed by Sanger sequencing. Immunohistochemistry results for ER, and PR were negative in 2 out of 10 patients, while the results of HER-2 and CK5/6 were negative in all the cases. A missense mutation in exon 18 of BRCA1 and a nonsense mutation in exon 25 of in BRCA2 were detected in one patient each. Both patients belonged to luminal A subtype. Despite the low number of patients in this study, it could be concluded that mutations in BRCA1 and BRCA2 occur in male breast cancer patients of luminal A subtype. The negative status of the tissue markers could not be used for the prediction of BRCA mutations. PMID:27478808

Toxoplasma gondii is one of the most common protozoan parasites with widespread distribution globally. It is the causative agent of Toxoplasma infection, which is prevalent in human and other warm-blooded vertebrates. While T. gondii infection in healthy people is usually asymptomatic, it can lead to serious pathological effects in congenital cases and immunodeficient patients. We sought to identify the seroprevalence rate of Toxoplasma infection in the Iranian general population to develop a comprehensive description of the disease condition in Iran for future use. Electronic databases (PubMed, Google Scholar, Science Direct, and Scopus) and Persian language databases (Magiran, Scientific Information Database [SID], Iran Medex, and Iran Doc) were searched. Furthermore, graduate student dissertations and proceedings of national parasitology congresses were searched manually. Our search resulted in a total of 35 reports published from 1978 to 2012.These include 22 published articles, 1 unpublished study, 8 proceedings from the Iranian conference of parasitology, and 4 graduate student dissertations, resulting in 52,294 individuals and 23,385 IgG seropositive cases. The random errors method was used for this meta-analysis. The result shows that the overall seroprevalence rate of toxoplasmos is among the general population in Iran was 39.3% (95% CI=33.0%-45.7%). There was no significant difference in the seroprevalence rate between male and female patients. A significant linear trend of increasing overall prevalence by age was noted (P<0.0001). In addition, the data indicates that there are high seroprevalence in groups who have direct contact with cats, consume uncooked meat and raw fruits or vegetables, in farmers and Housewife, individuals who have a low level of education, and live in rural areas. To the best of our knowledge, this is the first systematic review of T. gondii infection seroprevalence in Iran, which shows a high prevalence of Toxoplasma infection

Aim: Professional commitment has been widely discussed during the last decade. There is no comprehensive definition about “professional commitment in Iranian nurses.” Hence, this study was conducted with the aim of analyzing the concept of professional commitment in Iranian nurses. Materials and Methods: Hybrid model was used in three phases. Firstly, in the theoretical phase, data were retrieved from the CINHAl, MEDLINE, PubMed, OVID, Google scholar, and SID databases. The literature search used the keywords “professional commitment” and “nursing.” The final sample included 27 papers published in English between 2001 and 2011.Secondly, in the fieldwork phase, deep interviews with five clinical nurses were carried out, and thirdly, in the final analytical phase, the obtained data from theoretical and fieldwork phases were combined and a comprehensive analysis was conducted. Results: Loyalty and tendency to remain in the profession and responsibility to the professional issues were extracted in theoretical phase. Commitment to promote caring abilities, satisfying of being a nurse, and belonging to the nursing profession were obtained in fieldwork phase. Finally, two main themes including “commitment to offering the best nursing care” and “commitment to promotion of the nursing profession” were extracted. Conclusion: Nursing is a humanistic profession; it has some particular characteristics due to the profession’s nature. In this paper, a definition composed of two main dimensions of professional commitment in nursing has been introduced. PMID:23922592

Background: In different studies, the prevalence of tobacco consumption has been growing in high schools boys. Objectives: This study was conducted to determine the prevalence of smoking and its related factors among Iranian high school students in 2011. Materials and Methods: In this cross-sectional study, 450 male students from 15 high schools of Shahroud (northeast of Iran) were selected for evaluation of the knowledge, attitude and practices (KAP) of students regarding tobacco consumption. Results: Overall, 51% (95% CI: 46.5 - 55.7) of the students had positive history of smoking for at least one time and 7.1% (95% CI: 5 - 10) of them were current smokers. The most prevalent source of information about smoking was TV and radio programs (48%) and friends were the second source (22%). Based on the students’ opinions, entertainment and smoker friends were the most important reasons for smoking tendency. There was significant statistical association between students smoking and positive family history of smoking (P value < 0.05). Conclusions: The prevalence of smoking experince was very high among high school students. The most prevalent source of information about smoking was Iranian broadcasting companies. Positive family history of smoking and smoker friends were the important motivating factors toward smoking. PMID:26834798
Background The aim of this study was to assess the status of knowledge translation (KT) in Iranian medical science universities in order to assess the strengths and weaknesses of the most important organizations responsible for producing knowledge in the country. Methods The KT activities were assessed qualitatively and quantitatively in nine universities using the Self-Assessment Tool for Research Institutes. Results The strengths and weaknesses of universities were determined using seven main themes: priority setting; research quality and timeliness; researchers’ KT capacities; interaction with research users; the facilities and prerequisites of KT; the processes and regulations supporting KT; and promoting and evaluating the use of evidence. The quantitative and qualitative results showed that the Iranian universities did not have an appropriate context for KT. There were significant shortcomings in supportive regulations, facilities for KT activities, and the level of interaction between the researchers and research users. Conclusions The shortcomings in KT were mostly in the area of stewardship and policymaking (macro level), followed by planning and implementation at the universities. In order to strengthen KT in Iran, it should occupy a prominent and focused role in the strategies of the country’s health research system. PMID:24225146

The first-cultured and most-studied spiroplasma is Spiroplasma citri, the causal agent of citrus stubborn disease, one of the three plant-pathogenic, sieve-tube-restricted, and leafhopper vector-transmitted mollicutes. In Iranian Fars province, S. citri cultures were obtained from stubborn affected citrus trees, sesame and safflower plants, and from the leafhopper vector Circulifer haematoceps. Spiralin gene sequences from different S. citri isolates were amplified by PCR, cloned, and sequenced. Phylogenetic trees based on spiralin gene sequence showed diversity and indicated the presence of three clusters among the S. citri strains. Comparison of the amino acid sequences of eleven spiralins from Iranian strains and those from the reference S. citri strain GII-3 (241 aa), Palmyre strain (242 aa), Spiroplasma kunkelii (240 aa), and Spiroplasma phoeniceum (237 aa) confirmed the conservation of general features of the protein. However, the spiralin of an S. citri isolate named Shiraz I comprised 346 amino acids and showed a large duplication of the region comprised between two short repeats previously identified in S. citri spiralins. We report in this paper the spiralin diversity in Spiroplasma strains from southern Iran and for the first time a partial internal duplication of the spiralin gene.

Patterns of serum biochemical parameters vary among horse breeds. The objective of the present study was to compare serum lipoproteins of Iranian Caspian ponies with those of other horses (Arabs and Thoroughbreds) in the Iranian region. Serum lipoprotein values were determined by agar-agarose gel electrophoresis and measured by scan densitometry. Moreover, serum triglyceride and cholesterol concentrations were determined and the results were analysed by one-way analysis of variance. Serum triglyceride and cholesterol values were 1.13 +/- 0.23 and 2.38 +/- 0.18 mmol/l in Caspian ponies, 1.96 +/- 0.49 and 1.92 +/- 0.25 mmol/l in Arab horses and 1.38 +/- 0.26 and 2.17 +/- 0.53 mmol/l in Thoroughbred horses. The relative percentages of alpha- (72.63 +/- 17.76%) and beta-lipoproteins (29.10 +/- 5.49%) in serum electrophoretic tracings from Caspian ponies were not significantly different from those of other horses (p > 0.05). The lipoprotein phenotype in Caspian ponies may be useful for evaluating metabolic diseases.

Background: To respond efficiently to the increasing and new needs of people in health issues, it is necessary for nurses to develop their knowledge from hospital to society and to be equipped to play entrepreneur role in different levels of care. The present study was conducted to describe Iranian entrepreneur nurses’ perceived barriers to entrepreneurship, in order to identify the existing barriers. Materials and Methods: This is a qualitative study in which Graneheim and Lundman's content analysis method was employed. Thirteen entrepreneur nurses were chosen purposively, and data were gathered by unstructured interviews. Results: As a result of the data analysis, five major themes were extracted: Traditional nursing structure, legal limitations, traditional attitudes of governmental managers, unprofessional behaviors of colleagues, and immoral business. Conclusions: The findings of the present study show that Iranian nurses are confronted with various problems and barriers to enter entrepreneur nursing and keep going in this area. By focusing on such barriers and applying appropriate changes, policymakers and planners in health can facilitate nurses entering into this activity. PMID:26985222

Background: Protecting households against financial risks is one of objectives of any health system. In this regard, Iran’s fourth five year developmental plan act in its 90th article, articulated decreasing household’s exposure to catastrophic health expenditure to one percent. Hence, this study aimed to measure percentage of Iranian households exposed to catastrophic health expenditures and to explore its determinants. Methods: The present descriptive-analytical study was carried out retrospectively. Households whose financial contributions to the health system exceeded 40% of disposable income were considered as exposed to catastrophic healthcare expenditures. Influential factors on catastrophic healthcare expenditures were examined by logistic regression and chi-square test. Results: Of 39,088 households, 80 were excluded due to absence of food expenditures. 2.8% of households were exposed to catastrophic health expenditures. Influential factors on catastrophic healthcare were utilizing ambulatory, hospital, and drug addiction cessation services as well as consuming pharmaceuticals. Socioeconomics characteristics such as health insurance coverage, household size, and economic status were other determinants of exposure to catastrophic healthcare expenditures. Conclusion: Iranian health system has not achieved the objective of reducing catastrophic healthcare expenditure to one percent. Inefficient health insurance coverage, different fee schedules practiced by private and public providers, failure of referral system are considered as probable barriers toward decreasing households’ exposure to catastrophic healthcare expenditures.

Background: Pregnancy rate among Iranian adolescents below 20 years of age is increasing. Pregnancy during adolescence is considered a social issue associated with medical, emotional, and social outcomes for the mother, child, and family. The current research examines the experience of pregnancy among Iranian adolescents. Materials and Methods: The qualitative content analysis method was used. A purposive sample of 14 pregnant adolescents was enrolled in the study. Deep interviews were carried out with them. Results: Three themes were came up after analyzing the interviews: 1. Psychological reactions including three subthemes of feelings, concerns, and fears; 2. physical reactions including the subthemes of symptoms and feelings; and 3. spiritual reactions including religious beliefs and faith. Conclusions: The present study showed that for the purpose of assessing pregnancy in adolescents, one should consider the context and culture in which the adolescent lives. This is because factors such as preplanned or unwanted pregnancy and imposed or consensual marriage within or outside the family may draw different reactions from adolescents. Hence, all those factors need to be considered in order to plan health education during pregnancy for this age group. PMID:25949255

This study analyzes the total ozone column (TOC) variability over the Iranian plateau (Esfahan) from 1978 to 2011. Results show that the annual average of TOC in Esfahan tends to decrease with time, which is strongly dependent on the season, with maximum values during the winter-spring months (more than 2.2 %/decade). By applying a defined threshold that includes the TOC monthly -2σ, it is found that the maximum occurrence of low ozone events (LOEs) tends to be more frequent in the second half of year with about four-fifth of the observed LOEs (last summer, autumn, and early winter). During two cases of LOE, the tropopause height (TH) was uplifted ~2-4 km with temperature of 10 °C colder than the long-term mean, and the synoptic pattern was characterized by high-pressure systems in UTLS region. The extreme LOEs were consistent with the horizontal transport of ozone-poor air toward the Iranian plateau and vertical advection in UTLS region. The former mechanism plays a primary role in formation of extreme LOEs based on the observed TOC reductions during previous days over the source regions (Sahara desert and Himalaya region). Day-to-day variations of maximum UV index during LOEs show that by a decrease in TOC ~14 %, while the aerosol optical depth (AOD) in the cloudless condition reach their lowest rates (lower than 0.3), UV radiation exceeds very high and extreme levels in late winter and mid-spring, respectively.

Social responsibility is intertwined with nursing; however, perceptions of Iranian nurses about social responsibility has not been explored yet. This study, as part of a larger qualitative grounded theory approach study, aims to explore Iranian nurses' perception of social responsibility. The study participants included 10 nurses with different job levels. The study data were generated through semi-structured interviews. The participants were selected through purposeful sampling approach, which was then followed by theoretical sampling until reaching the point of data saturation. All the interviews were recorded, transcribed, and analyzed through constant comparative analysis. Positive human characteristics, professional competencies, professional values, solution-focused nursing care, and deployment of professional performance are five categories obtained from the study. The participants believed socially responsible nurses to have positive personality characteristics as well as the necessary skills to do their duties accurately. Such nurses also respect the values, observe the professional principles, and take major steps toward promotion and deployment of the nursing profession in the society.

Context: Hepatitis A virus (HAV) infection is an important public health problem. It is estimated that about 1.4 million cases of HAV infection occur every year worldwide. Non-immune healthcare workers (HCWs) can be at higher risk of HAV infection in comparison to general population and an appropriate preventive method should be considered for them. Evidence Acquisition: For finding related articles, a comprehensive search was performed in Scopus, PubMed and Google Scholar and all appropriate combinations of following keywords were considered; “healthcare provider”, “healthcare personnel”, “healthcare worker”, “nurse” “medical students”, “Iran”, “Hepatitis A” and “vaccination”. Also we did a search in Persian language in Google scholar and scientific information database (SID) to find related Persian literature. Results: A gradual shift in age of HAV infection has been seen from childhood toward adulthood. Data about HAV seropositivity among Iranian HCWs are very limited. However based on the recent studies, it seems that HAV seropositivity has been reduced among HCWs in comparison with the past. All recent studies have suggested HAV vaccination for HCWs. Conclusions: Available limited studies show that Iranian healthcare personnel need HAV vaccination. However, for selecting an appropriate preventive method for this high risk group, more original studies are still needed. PMID:26977171

Porphyrias are rare metabolic hereditary diseases originating from defects in specific enzymes involved in the heme biosynthesis pathway. Congenital erythropoietic porphyria (CEP) is the rarest autosomal recessive porphyria resulting from a deficiency of uroporphyrinogen III cosynthase (UROS), the fourth enzyme in heme biosynthesis. CEP leads to an excessive production and accumulation of type Ι porphyrins in bone marrow, skin and several other tissues. Clinical manifestations are presented in childhood with severe cutaneous photosensitivity, blistering, scarring and deformation of the hands and the loss of eyebrows and eyelashes. Less than 200 cases of CEP have been reported to date. Four CEP patients and their family members were studied for the first time in Iran. A missense mutation in the UROS gene was identified in this family. A, T to C change at nucleotide 34313, leading to a substitution of Leucine by Proline at codon 237, was observed in the homozygous state in these 4 patients and heterozygous state in their parents. Our data from the Iranian population emphasizes the importance of codon 237 alone, given the rarity of this disease. This fact can be taken into consideration in the mutational analysis of UROS. This work emphasizes the advantages of molecular genetic techniques as diagnostic tools for the detection of clinically asymptomatic heterozygous mutation carriers as well as CEP within families.

Background: Thoracoscopic treatment of esophageal atresia and tracheoesophageal fistula (EA+TEF) is accepted as a superior technique at least in cosmetic point of view but it is considered as an advance endoscopic procedure that needs a learning curve to be performed perfectly. This is the first report of Iranian group pediatric surgeons in thoracoscopic approach to EA. Methods and Materials: Since 2010, twenty four cases with EA+TEF underwent thoracoscopic approach in Sarvar Children Hospital (Mashhad -Iran). During the first 6 months, thoracoscopic approach to 6 cases of EA+TEF was converted to open procedure because of technical and instrumental problems. The first case of successful thoracoscopic EA repair was accomplished in 2010 and since then, 10 cases of EA+ TEF among 18 patients were treated successfully with thoracoscopic approach Results: Overall conversion rate was 58.3% but conversion rate after the primary learning curve period, was 35.7%. The main conversion causes include difficulties in esophageal anastomosis, limited exposure and deteriorating the patient's condition. Anastomotic leak and stenosis were observed in 20% and 40% respectively. Overall mortality rate was 4.2%. Conclusion: Thoracoscopic repair of esophageal atresia seems feasible and safe with considerable superiorities to the conventional method although acceptable results needs a prolonged learning curve and advanced endoscopic surgical skill. Clear judgment about the best surgical intervention for EA according to all cosmetic and functional outcomes needs further studies. PMID:27471677
Afghan refugees in Iran, like many Muslims around the world, think that using contraceptives is against their religious beliefs. The majority of Iranians also thought so until a decade ago. Since then an all-encompassing social movement has emerged in Iran in which women and young people have played decisive roles. This movement has led to an attitude shift towards acceptance of family planning across Iranian society. High-ranking clerics, responding to the social movement, issued progressive edicts indicating that poor families could practise family planning. This paper reports the findings of focus group studies carried out among Afghan refugee men in two communities in Iran. The findings indicate that exposure to Iranian life, especially the rulings of Iranian clerics, have influenced Afghans' views on family planning. The findings also indicate that a system of justification is needed to help people avoid both social sanctions and individual stresses resulting from a controversial practice regarded as a sin for centuries.

This study constructed an anthropometric data bank for the Iranian working population. In total, thirty-seven body dimensions were measured among 3720 Iranian workers with different ethnicities (3000 male and 720 female; aged 20-60 years). Statistical analysis revealed significant differences for most of body dimensions among the ethnical groups. Moreover, the authors compared Iranian anthropometric characteristics with those of four Asian populations: Taiwanese, Chinese, Japanese, and Korean. Overall, 16 body dimensions for the five Asian populations were selected and compared. Accordingly, different morphological characteristics of these five populations were observed. The Iranian population showed wide shoulders and hips and long legs; the Chinese population showed narrow hips and shoulders and a short height relative to the other populations. The Korean sample recorded moderate body size comparing the other populations. The Taiwanese had large hands, relatively wide shoulders and short upper limbs. These differences in population dimensions should be taken into consideration for product and process design when expanding regional markets.

Abstract Background and Objectives: Identify the factors affecting quality of life (QOL) is one of the major goals for improving the Health Related Quality Of Life (HR-QOL) in patients suffering from Congestive Heart Failure (CHF). Considering the fact that there are few published studies in this regard in Iran, as a developing country, this research was designed to determine the HR-QOL in Iranian CHF patients and its related factors. Methods and Materials: In this cross-sectional study, random sampling was used to select 1840 female CHF patients. After obtaining informed consent, patients' demographic and disease-related data (using a researcher-made questionnaire which assessed eight dimensions including role-physical, physical functioning, bodily pain, general health, vitality, role-emotional, social functioning and mental health), and the HR-QOL data (using the SF-36 questionnaire) were assessed and analyzed with SPSS version 15. Results: A high proportion of the participants had an unfavorable HR-QOL in physical functioning (44.56%), role-physical (49.55%), role-emotional (59.83%), mental health (54.50%), and general health (53.36%) dimensions and a relatively favorable HR-QOL in social functioning (50.57%), vitality (49.26%), and body pain dimensions (52.55%). A significant relationship was found between the HR-QOL and the employment status, level of education, being cared for at home, functional capacity, disease duration, frequency of medical encounter and hospitalization, duration of hypertension and concurrent CHF, presence of edema, presence of disease symptoms and morbidities, intensity of fatigue at the study time and previous months, and the type of medications. Conclusion: According to the results, QOL in CHF patients was unfavorable in the scales of general health, role-emotional, and mental health.

Background: Hand Eczema (HE) is a dermatological disorder with frequent relapses and multiple causes such as atopic, allergic and irritant contact dermatitis. The management is complex because of the wide range of different pathogenesis. Efficacy of some of available treatments is not well established and it can affect patients’ quality of life significantly. Methods: Reports on HE such as diagnosis, pathophysiology, pharmacological and nonpharmacological therapy that described in medieval Iranian medicine, were gathered and analyzed from selected medical and pharmaceutical textbooks of Iranian Traditional Medicine (ITM). The search of databases such as PubMed, EMBASE/Excerpta Medica, Science direct, Scopus, Google scholar, Web of science, Sid, Iran medex, Irandoc, was performed to reconfirm the efficacy of ITM remedies in conventional medicine from 1980-Jan-1 to 2015-Dec-30. Results: According to their opinion, HE is highly associated with liver function. This disorder was categorized into two main types as wet and dry ones. Most Iranian textbook explained signs of HE, as excessive skin itching, redness, burning and dryness. Treatments recommended by Iranian scientists were lifestyle modification, dietary intervention and performing the rules of prevention as well as herbal therapy and special manipulations. Conclusion: Iranian practitioners believed that, six essential principles, diet therapy and medicinal plants have high impact on treatment of HE. These remedies based on Iranian scholar’s experiences might be useful for further studies to the management of HE. PMID:27928524

Background: The aim of this study was to survey the Iranian Parasitology researchers’ performance, and analyse and visualize the scientific outputs of their co-authorship network. Methods: This study was conducted using scientometric method and social network analysis (SNA). The data extracted from the Web of Science (WoS) databases in July 10th 2014. Totally, 1048 documents of all types in research area of Parasitology during 1972–2013 by Iranian researches retrieved. The co-authorship map was drawn utilizing NETDRAW, Coauthor.exe, and UCINET softwares and was analysed based on SNA measures. Results: The researchers’ co-authorship network consisted of 78 authors and its density degree is 0.57. “Mohebali” ranked top in all of centrality measures. The most of the publications were related to 2012, “Mohebali” with about 9% of all documents was the Iranian most prolific author in Parasitology field. The Iranian researches have published mostly (266 documents) in “Iranian Journal of Parasitology”, and the most of the documents belong to “Tropical Medicine” subject field. The most of Iranian researchers’ scientific cooperation was performed with England and United States. Conclusion: Bringing forth density degree (is 0.57) showed that this network has an almost medium density. Indeed, the authors have had relations in moderate level with each other in the network. The findings of this study can be identified aspects of scientific collaboration, and help policy makers of Parasitology field research. PMID:28096854
Iranian soldiers were attacked with chemical bombs, rockets and artillery shells 387 times during the 8-years war by Iraq (1980–1988). More than 1,000 tons of sulfur mustard gas was used in the battlefields by the Iraqis against Iranian people. A high rate of morbidities occurred as the result of these attacks. This study aimed to evaluate the delayed toxic effects of sulfur mustard gas on Iranian victims. During a systematic search, a total of 193 (109 more relevant to the main aim) articles on sulfur mustard gas were reviewed using known international and national databases. No special evaluation was conducted on the quality of the articles and their publication in accredited journals was considered sufficient. High rate of morbidities as the result of chemical attacks by sulfur mustard among Iranian people occurred. Iranian researchers found a numerous late complications among the victims which we be listed as wide range of respiratory, ocular, dermatological, psychological, hematological, immunological, gastrointestinal and endocrine complications, all influenced the quality of life of exposed victims. The mortality rate due to this agent was 3%. Although, mortality rate induced by sulfur mustard among Iranian people was low, variety and chronicity of toxic effects and complications of this chemical agent were dramatic. PMID:23351810

Background: The area of e-Health is broad and has an excellent growth potential. An increasing number of experts believe that e-Health will fuel the next breakthroughs in health system improvements throughout the world, but there is frequent evidence of unsustainable use of e-Health systems in medical centres, particularly hospitals, for different reasons in different countries. Iran is also a developing country which is presently adopting this promising technology for its traditional healthcare delivery but there is not much information about the use of e-Health systems in its hospitals, and the weakness and opportunities of utilization of such Hospital Information Systems (HIS). Methods: For this research, a number of Hospitals from Isfahan, Iran, are selected using convenient sampling. E-health research professionals went there to observe their HIS and collect required data as a qualitative survey. The design of interview questions was based on the researchers’ experiences and knowledge in this area along with elementary interviews with experts on HIS utilization in hospitals. Results: Efficient administration of e-health implementation improves the quality of healthcare, reduces costs and medical errors, makes healthcare resources available to rural areas, etc. However, there are numerous issues affecting the successful utilization of e-health in Hospitals, such as a lack of a perfect HIS implementation plan and well-defined strategy, inadequate IT-security for the protection of e-health-related data, improper training and educational issues, legal challenges, privacy concerns, improper documentation of lessons learned, resistance to the application of new technologies, and finally a lack of recovery plan and disaster management. These results along with some informative stories are extracted from interview sessions to uncover associated challenges of HIS utilization in Iranian hospitals. Conclusion: The utilization of e-health in Iranian hospitals
This study was designed to explore the sex and group differences in histrionic personalities of high school and university students, and also to explore the results of this study with those of Crown and Crisp from 1966 in England. A sample of 160 high school students (80 girls and 80 boys) were selected randomly from four high schools in Shiraz and Shiraz University. The mean ages for high school girls and boys were 15.3 and 17.3 yr., for university women and men were 20.6 and 23.2 yr., respectively. The hysteria (H) scale of the Middlesex Hospital Questionnaire was used. The questions of this scale refer to histrionic personality according to DSM-III and DSM-III--R. Analysis showed significant effects of group (high school, college) for histrionic personality disorder. It was concluded that more histrionic personality disorders were reported among British college students than among their Iranian peers.

This descriptive survey research was undertaken to design appropriate programs for the creation of a positive perception of nanotechnology among their intended beneficiaries. In order to do that, the factors affecting positive perceptions were defined. A stratified random sample of 278 science board members was selected out of 984 researchers who were working in 22 National Agricultural Research Institutions (NARIs). Data were collected by using a mailed questionnaire. The descriptive results revealed that more than half of the respondents had "low" or "very low" familiarity with nanotechnology. Regression analysis indicated that the perceptions of Iranian NARI Science Board Members towards nanotechnology were explained by three variables: the level of their familiarity with emerging applications of nanotechnology in agriculture, the level of their familiarity with nanotechnology and their work experiences. The findings of this study can contribute to a better understanding of the present situation of the development of nanotechnology and the planning of appropriate programs for creating a positive perception of nanotechnology.

Manual material handling (MMH) tasks can be found in most workplaces and they may constitute a risk factor for work-related musculoskeletal disorders (WMSDs). This study was conducted to determine the prevalence of WMSDs and to compare MMH loads with the acceptable weight and force limits among Iranian casting workers. Data were collected from 50 workers of casting workshops who performed MMH tasks. The Nordic musculoskeletal disorders questionnaire and the Snook tables were used as tools for data collection. Hand/wrist symptoms were the most prevalent problems among the workers (84%). The results of the Snook tables showed that the loads in lifting (84%), lowering (86%), carrying (66%), pushing with initial (43%) and sustained force (59%), and pulling tasks with initial (48%) and sustained force (93%) exceeded recommended limits. WMSDs occurred in high rates among the workers and, thus, ergonomics interventions should focus on decreasing WMSDs and redesigning MMH tasks.

The Iranian Plateau, being formed as a consequence of the on-going Arabia-Eurasia collision, is a natural laboratory for understanding mountain/plateau building processes and deep dynamics related to the early phases of continent-continent collision. A key issue in the study of the Iranian Plateau is to acquire detailed information about the structure and deformation of the crust and mantle. For this purpose, we (IGGCAS, RIESGSI, IASBS) deployed a new temporary broadband seismic array in NW Iran, under a multidisciplinary collaborative project named "China-Iran Geological and Geophysical Survey in the Iranian Plateau (CIGSIP)". The new array consists of three linear sub-arrays running northeastward from the south of the Zagros Fold and Thrust Belt to the coast area of the southern Caspian Sea, forming an observational corridor of ~550-km long and ~150-km wide. The main sub-array consists of 46 stations with station spacing of 10-15 km. Eight and nine additional stations were located ~75 km to the west and east, respectively, of the main sub-array to provide 3D constraints on the deep structure. All the 63 stations operated for about one year from October 2013 to October 2014. We investigate the crustal and upper mantle structure beneath this new seismic array by combining P- and S-receiver function (RF) images with ambient noise tomography and gravity modeling results. Our images reveal substantial structural variations in the crust of different tectonic units that are bounded by major strike-slip faults. The Main Zagros Reverse Fault (MZRF), generally considered as the suture between the Arabian and Eurasian plates, was imaged to dip to NE, separating an overall slow crust but with a faster and denser lowermost part in the SW Arabian side from a relatively fast crust, especially a fast middle-lower crust in the NE Iranian side. Structural differences are also observed between the Alborz Mountains and the southern Caspian Sea where an apparent Moho step (~18 km

In this article, Iranian Noble Gas Analyzing System (INGAS) will be introduced. This system is based on beta-gamma coincidence technique and consists of a well-type NaI(Tl) as gamma or X radiation detector and a cylindrical plastic scintillator to detect beta or conversion electron. Standard NIM modules were utilized to detect coincidence events of detectors. Both the beta and gamma detectors were appropriately calibrated. The efficiency curve of gamma detector for volume geometry was obtained by comparing the results of gamma point sources measurements and simulations of GATE V7.0 Monte Carlo code. The performance of detection system was checked by injection of 222Rn and 131mXe gaseous source in the detection cell. The minimum detectable activity of the system for 133Xe is 1.240±0.024 mBq for 24 h measurement time.

Background Cancer diagnosis for everybody may be perceived as crisis and breast cancer, as the most common malignancy in women, can influence their well-being and multiple aspects of their health. So understanding that how women in various contexts and communities adjust to the illness is necessary to facilitate this adjustment and improve their quality of life. Objectives The aim of this study was to: 1) identify the core components of coping strategies to adjust to the illness in Iranian women with breast cancer perspective, 2) to develop and determine psychometric properties of a native self-report instrument to assess coping behaviors and measure the degree of adjustment with the breast cancer. Methods The present exploratory mixed method study was conducted in two consecutive stages: 1) the hermeneutic phenomenological study was done to explore the life experiences of coping styles to adjust with the breast cancer using in-depth interviews with patients that lead to item generation; 2) psychometric properties (validity and reliability) of the instrument were evaluated recruiting 340 eligible women. The item pool was reduced systematically and resulted in a 49-item instrument. Results From the qualitative stage, item pool containing 78 items related to coping strategies to adjust with the breast cancer. After eliminating unwanted statements from the results, qualitative and quantitative face and content validity, the 10 factors extracted employing construct validity were: feeling of guilt, abstention-diversion, role preservation and seeking support, efforts for threat control, confronting, fear and anxiety, role wasting, maturation and growth, isolation, and fatalism. These factors accounted for the 59.1% of variance observed. The Cronbach reliability test was carried out and alpha value of 10 factors was calculated from 0.78 to 0.87 confirming all factors were internally consistent. The scale’s stability was tested using the test-retest method. Conclusions

Statement of the Problem: Denture stomatitis is the common form of oral candidiasis, which is seen in the form of diffused inflammation in the areas covered by dentures. Many primary studies report the prevalence of denture stomatitis and candida albicans among patients in the Iranian population; therefore, using meta-analysis is valuable for health policy makers. Purpose: The purpose of the present study is to determine the prevalence of denture stomatitis and candida albicans in Iran. Materials and Method: Using relevant keywords, national and international databases were searched. After limiting the search strategy and deleting the duplicates, the remaining papers were screened by examining the title and abstract. In order to increase the sensitivity of search reference lists of papers were examined. Finally the index of heterogeneity between studies was defined using Cochran test (Q) and I-squared (I2). According to heterogeneity, the random effects model was used to estimate the prevalence of denture stomatitis and candida albicans in Iran. Result: The prevalence of denture stomatitis in 12 studies, and the prevalence of candida albicans in patients with denture stomatitis have been reported in 6 studies. The number of sample under investigated and its age range among primary studies included meta- analysis was 2271 individuals and 32.7 till 87.5 years respectively. The prevalence of denture stomatitis in preliminary studies imported to a meta-analysis varied from 1.9% to 54.6%, and its rate in Iran using the meta-analysis was estimated 28.9 % (CI 95%: 18.2-39.6). Also the overall prevalence of candida albicans in patients with denture stomatitis in Iran was estimated 60.6% (CI 95%:50.1-71.2). Conclusion: This study showed that the prevalence of denture stomatitis and candida albicans among patient infected denture stomatitis is relatively significant in Iran. PMID:27840842

Skillful and efficient human resource is one of the most important tools for reaching the organizational targets and it is almost impossible to reach the predetermined goals and success without having skillful human resources. Therefore, having a study on the personnel’s job satisfaction is recommended for all of the organizations. Since the health organizations are among the most important organizations of any country, paying attention to the nurses’ job satisfaction as the main providers of the health care services gets very important. In fact, their attempts guarantee the efficient human resources’ health in the society. Understanding the Iranian nurses’ experiences of their job satisfaction. The present paper studies the implicit and explicit aspects of the clinical nurses’ job satisfaction. The needed information is collected via interviews, and then the participants’ contextual data is analyzed by the qualitative content analysis. The research results introduce the altruism as the foundation for the nurses’ job satisfaction. Altruism is composed of three categories of the patient advocacy, spiritual job satisfaction, and professional commitment. Altruism has made the nurses deliver the required health cares to the patients with all their love, while their profession has many difficulties. Job satisfaction resulted from altruism is experienced as a pleasant feeling along with enjoyment resulted from addressing the needs of a patient who looks forward to the nurse’s advocacy. According to this kind of job satisfaction, the nurse’s professional commitment is to advocate for the patient. Also, the research results show that spirituality is the inseparable component of altruism and it has a vital role in the nurses’ job satisfaction. The spirituality helps the nurses to deliver targeted acts and interventions. PMID:27045394

The relationship between ABO blood group distribution and Peptic Ulcer Disease (PUD) has been widely evaluated in the past. But data concerning the same evaluation are very limited in Iran. This study sought to determine the distribution of ABO blood group in patients with PUD in Iranian subjects. Eighty-one patients with PUD (51 male and 30 female; mean age: 49 +/- 18 years) who attended our endoscopy section were enrolled. Blood samples were used for ABO/Rhesus (Rh) blood group antigen typing. The ABO blood group phenotype distribution in subjects was as follows: 37.1% (30/81) for group A, 23.4% (19/81) for group B, 35.6% (28/81) for group O and 4.9% (4/81) for group AB. Rh positivity was found in 63% (51/81) of patients. In local healthy population, ABO/Rh blood group distribution was 33.8, 20.7, 34.7, 8.4 and 89.6% for A, B, O, AB and Rh, respectively. AB blood group distribution in healthy population was higher than PUD (8.4 vs 4.9%). In contrast, Rh positivity of PUD in Iran is lower than healthy subjects (63 vs 89.6%). Variation in the results of studies is related to different study communities. According to these results, probably ABO/Rh blood group has an important role in patients with peptic ulceration. The functional significance of ABO blood group distribution might be associated with biological behavior of PUD. The impact of blood group on PUD may be a focus for further studies.

Introduction: To achieve a valid evaluation of faculty members, it is necessary to develop an inclusive and dynamic system of evaluation addressing all the activities and responsibilities of faculty members. Among these responsibilities, educational activities comprise an important part which needs to be investigated. This study aimed to investigate the current system of evaluating the faculty members’ educational duties. Methods: In this descriptive cross-sectional study, a checklist for investigating the current evaluation system and was developed confirmed by a focus group. The data for checklist were collected through a researcher-made questionnaire and interview with eight experts of faculty evaluation that worked in different Iranian Medical Universities. For completion of information, the available documents and records were studied. Finally, the current evaluation system of different universities was depicted. Results: The developed checklist had six themes and 123 subthemes. The extracted themes included: Tools, evaluators, processes, appropriateness of faculty field of work with evaluation, feedback status, and university status regarding decisions made based on faculty evaluation results. As for comprehensiveness, all evaluation items except for evaluation and assessment skills and religiosity from personality traits subtheme were fully investigated. The evaluation tools were not enough for different types of education such as clinical education. In six universities, the feedbacks provided were only for making inter/intra department comparison, and no scientific suggestions were included. The results of evaluations were used only for the faculties’ promotions. Discussion: Suitability between evaluation and performance components is a necessity in every evaluation system. The study showed this does not exist in Iranian Universities. For instance, there was no appropriate tool for the evaluation of clinical education. Also, the results of the faculty

Purpose Taekwondo, as the most popular martial art among Iranian sportsmen, might lead to injury for the athletes of this sport during competitions. We decided to report the incidence rate of injuries sustained by the athletes of this sport during national competitions. Methods All competitions of Iran national championship taekwondo league in 2006-2007 with 204 athletes were observed prospectively to detect the occurrence of injuries. The severity of injuries was classified into four groups (mild, moderate, severe, and critical) according to the involvement of medical care team in the contest, ability of the athletes to resume and duration of probable absence of injured athletes from future competitions and training sessions. Athlete-Exposure (A-E) was defined as the number of competitions multiplied by two. On this base, the rate of injury incidence per 1000 A-Es, the rate of injuries per time unit and the rate of injury occurred for each 100 athletes were considered as the major outcomes of this study. Results Of totally 1,338 A-Es, 93 injuries were recorded during the competitions. The rate of injury incidence was found to be 69.5 injuries per 1000 A-Es and the rate of injuries per minute of competitions was 0.023 which corresponded to 23.3 injuries per 1000 minutes of competitions. 45.6 injuries were occurred for each 100 athletes during the course of competitions. The most frequent injuries were mild (68.8%) and critical injuries (24.7%), followed by moderate and severe injuries; 4.3% and 2.1%, respectively. Conclusion The rate of injury we found was lower than that of western countries. In spite of finding the lower limbs as the most frequent place of injuries in other studies, we found the upper limbs as the most predisposed place of injuries which might be due to difference in the method of combat of Iranian athletes with other athletes.

Sleep problems are common in childhood, but there are limited studies regarding that in Iranian children and awareness of the sleep problems and their complication in Iranian parents. We arranged this study in which parents of children attending for a sick visit or routine growth control to assess whether sleep problems are under-reported at general pediatric visits. In a cross-sectional study from April 2010 to April 2011 in 301 children aged 2-14 years old attending to pediatric clinics were enrolled. To investigate the general orientation of parents about their child sleep problem we asked them a global question at first regarding sleep of their child. After that, the Persian version of BEARS questionnaire was completed by them. Only 30 (9.9%) parents reported sleep problems in their children in response to primary global question but by collecting the data from BEARS questionnaire it was revealed 45.18% (136/301) of children had one or more of sleep disorders at all. As mentioned 136 (45.18%) children had slept problems of which the most frequent complaint (15.28%) was related to bedtime problems. The second complaint (11.96%) was awakening during the night children. A significant association between sleep problems and child gender was not found. Co-sleeping with parents was found in 55.48% of all children in this study. Despite the high prevalence and adverse effects of sleep disorders, the present study suggests that parents underreport sleep problems at consultation. We suggest children should be assessed for sleep disorders in monitoring and health screening visits.

As the biggest proportion of hospital personnel, Iranian nurses have a major role in providing quality care to patients. Nursing managers and nurses no longer feel that nurses' work is valued and they are concerned about their productivity. Nurses' views about productivity and management factors affecting it have been identified as the most important aspects affecting productivity. Thus, this study assesses productivity from the nurse's view. A grounded theory approach was used for this research. Purposive sampling and semistructured interviews were used. The data were analyzed using constant comparative analysis. Most participants felt that the qualitative nature (effectiveness) of productivity is very important. Also, participants indicated that management is the most important factor that can promote or impede their productivity. They suggested that managers' performance and their skill level are the factors influencing productivity. Effective management can improve nurses' productivity and the quality of care that nurses provide.

Background: Adequate calcium intake may have a crucial role with regards to prevention of many chronic diseases, including hypertension, hypercholesterolemia, different types of cancer, obesity and osteoporosis. In children, sufficient calcium intake is especially important to support the accelerated growth spurt during the preteen and teenage years and to increase bone mineral mass to lay the foundation for older age. Objectives: This study aimed to assess daily calcium intake in school-age children to ensure whether they fulfill the FGP dairy serving recommendations, the recommended levels of daily calcium intake and to assess the relationship between dietary calcium intake and major bone health indicators. Patients and Methods: A total of 501 Iranian school-age children were randomly selected. Calcium intake was assessed using a semi-quantitative food frequency questionnaire. Bone health indicators were also assessed. Results: Dairy products contributed to 69.3% of the total calcium intake of the children. Daily adequate intake of calcium was achieved by 17.8% of children. Only 29.8% met the Food guide pyramid recommendations for dairy intake. Dietary calcium intake was not significantly correlated with serum calcium and other selected biochemical indicators of bone health. Conclusions: The need for planning appropriate nutrition strategies for overcoming inadequate calcium intake in school age children in the city of Tehran is inevitable. PMID:26199684

Uterine leiomyomas are steroid-hormone dependent tumors of myometrial smooth muscle cells that affect numerous women throughout the world. Based on previous studies, we evaluated the mutations of MED12 gene which encodes a co-activator protein involved in transcription regulation of the vast majority of RNA polymerase II-dependent genes. Exon 2 of MED12 gene was genotyped by PCR-sequencing method. To determine the proportion of mutation-containing transcripts, RNA was extracted from the tissue samples and the corresponding amplified cDNA was sequenced. We observed 11 mutation positive lesions, 7 of them were located in codon 44. The c.131G>A was found to be the most common somatic mutation in this study. Our investigation also demonstrated two unreported mutations , one large deletion and one insertion. cDNA analyzing revealed that the mutated transcripts were predominantly expressed in almost all changes including the new insertion mutation c.122-123ins15. Our study provides further evidence that the MED12 somatic mutations occur in a heterozygous manner and are mostly missense mutations in codon 44. The results displayed 47.8% mutation positive lesions in Iranian patients confirming the diversity between the populations. PMID:26396919

Background Understanding sexual behavior before marriage is relatively rare in the East, especially in Islamic societies, because sexuality is a sensitive subject for many Muslims. Objectives The purpose of this study was to identify premarital sexual intercourse-related individual factors among Iranian adolescents. Patients and Methods This qualitative study was performed on 30 students of Payame Noor university of Shiraz city, Iran, in 2014. The study sample includes male and female university students selected using the convenience sampling method. Semistructured interviews were used to collect data. All interviews were conducted by the researcher in a comfortable atmosphere and carried out without the presence of others. Each interview lasted between 30 - 20 minutes. Interviews continued until data saturation occurred. Data were analyzed using the qualitative content analysis method. Participation in the study was voluntary by obtaining an informed consent. Results The study included 30 participants, 56.6% (n = 17) males and 43.4% (n = 13) females. The age range of study, participants was from 19 to 25 years of age. Data analysis showed that three main categories extracted in shaping premarital sexual intercourse in adolescents: health beliefs, religious-spiritual beliefs, and character. Conclusions This study can help find a culturally appropriate intervention to delay sexual initiation and prevent sexual behavior before marriage in adolescents and young adults. The results of the present study have both experimental and theoretical implications for future research. Finally, this study is a form of shared experience that can help similar studies.

Objective: Presence of genomic diversity among Helicobacter pylori (H. pylori) strains have been suggested by numerous investigators. Little is known about diversity of H. pylori strains isolated from Iranian children and their association with virulence of the strains. Our purpose was to assess the degree of genomic diversity among H. pylori strains isolated from Iranian-children, on the basis of vacA genotype, cagA status of the strains, sex, age as well as the pathological status of the patients. Methods: Genomic DNA from 44 unrelated H. pylori strains isolated during 1997–2009, was examined by pulse-field gel electrophoresis (PFGE). Pathological status of the patients was performed according to the modified Sydney-system and genotype/status of vacA/cagA genes was determined by PCR. PFGE was performed using XbaI restriction-endonuclease and the field inversion-gel electrophoresis system. Findings: No significant relationship was observed between the patterns of PFGE and the cagA/vacA status/genotype. Also no relationship was observed between age, sex, and pathological status of the children and the PFGE patterns of their isolates. Similar conclusion was obtained by Total Lab software. However, more relationship was observed between the strains isolated in the close period (1997–2009, 2001–2003, 2005–2007, and 2007–2009) and more difference was observed among those obtained in the distant periods (1997 and 2009). Conclusion: H. pylori strains isolated from children in Iran are extremely diverse and this diversity is not related to their virulence characteristics. Occurrence of this extreme diversity may be related to adaptation of H. pylori strains to variable living conditions during transmission between various host individuals. PMID:26019775

Seventeen provinces of Iran were surveyed during 2003-2012 to find Brassicaceae hosts of Cauliflower mosaic virus (CaMV). A total 397 samples were collected from plants with virus-like symptoms. Among those tested by ELISA, 255 samples (67.2 %) were found to be infected with CaMV. Mechanical transmission tests showed that the Iranian isolates have similar biological properties on a number of Brassica and Raphanus plant species and cultivars tested. However, the isolates varied in the severity of symptoms they induced and in the capacity to infect B. oleracea var. capitata, on the basis of which they were grouped into two distinct biotypes L/MMo (latent/mild mottle) and severe (S) infection. The molecular diversity of natural population of CaMV were investigated based on the complete sequences of OFR 6 of 36 Iranian isolates collected from different geographically distant regions in Iran alongside the sequences of 14 previously reported isolates. Phylogenetic analyses indicated that the Iranian CaMV isolates belong to two groups (GI and GII). Most of the Iranian isolates fell into GI with other exotic isolates; however, the isolates from North-East Iran with Xinjiang from China fell into GII. The phylogenetic group GII (the North-East Iranian isolates) closely corresponded to the S biological group however other Iranian isolates corresponded to the L/MMo biological group. The within-population diversity was lower than the between population diversity suggesting the contribution of a founder effect on diversification of CaMV isolates. The Iranian isolates were differentiated from other exotic CaMV isolates and clustered into two RFLP groups using Hpy99I which closely corresponded to the biological and phylogenetic groups. This study showed the evolutionary process in CaMV isolates is shaped by a combination of host range differentiation and nucleotide substitution using the approach of population genetics.

Objective To study the prevalence and correlates of increased urinary albumin excretion (UAE) in an Iranian type 2 diabetic population. Methods Over a one year period since October 2002, 400 consecutive type 2 diabetic patients referred to an outpatient diabetes clinic, were enrolled in a cross sectional study. Subjects had no history of renal impairment or overt proteinuria. Data concerning demographic characteristics and cardiovascular risk factors were recorded and height, weight and blood pressure were measured. Glucose, cholesterol, HDL-C, LDL-C, triglyceride, apoprotein B, lipoprotein a, creatinine, and HbA1c were measured in fasting blood samples. Overnight twelve-hour UAE were assessed by immunoturbidometry method. Regression analyses were employed to determine the correlates of UAE. Results Out of 400 patients, 156 (40%) subjects had increased UAE (UAE ≥ 30 mg/24 hour). The UAE was higher in males compared to females (145.5 vs. 72.1 mg/day; p < 0.05); however, the age and HDL adjusted UAE levels were not significantly different between men and women (120.1 vs. and 87.9 mg/day; p = 0.37). Increased UAE was correlated with decreasing HDL-C and a longer duration of diabetes independent of other variables; increased UAE was correlated with HbA1c as well.
