Sexual health outcomes of PLISSIT-based counseling versus grouped sexuality education among Iranian women with breast cancer: A randomized clinical trial.

In-person, individual counseling using the PLISSIT model is a well-known approach to help people with sexual problems. Evidence suggests that Grouped Sexuality Education (GSE) can be as effective as in-person sexuality education. The efficacy of PLISSIT versus GSE has not previously been evaluated in women with Breast Cancer (BC). In this paper, we report on the effect of PLISSIT versus GSE on self-reported sexual behaviors experienced by women after a BC diagnosis (n = 75). The women were randomly allocated into three groups, with 25 women in each arm. Data analysis of the intention-to-treat population (n = 65) revealed efficacy of both GSE and PLISSIT in improving sexual behaviors (p < 0.0001) with a positive change in sexual capacity, motivation and performance after 6- and 12-weeks post-intervention follow ups. We found the GSE model showed a greater efficacy than the PLISSIT model. Due to the substantial needs faced by women with cancer and the cost associated with implementing the PLISST model, GSE seems to be more effective. We recommend GSE for Iranian communities where management of sexual problems is at an early stage and where the sexuality of women with cancer is routinely overlooked.

Effect of topical marshmallow (Althaea officinalis) on atopic dermatitis in children: A pilot double-blind active-controlled clinical trial of an in-silico-analyzed phytomedicine.

Atopic dermatitis (AD) is a chronic relapsing eczematous skin disease, which primarily affects infants and young children. Due to the side effects of commonly used drugs for its treatment, the development of safer therapeutic strategies is needed. There are many reports on the topical use of marshmallow (Althaea officinalis) for a range of skin diseases in Persian medicine. The main aim of the present investigation was evaluating the efficacy of marshmallow in children with mild-to-moderate atopic dermatitis. Another aim of the study was screening the anti-allergic and anti-inflammatory potential of phytocomponents against target proteins, including TNF-alpha, IL6, and PDEs A, B, and D enzymes with PDB IDs: 2AZ5, 1P9M, 3I8V, 4KP6, and 1Y2K, respectively, along with their respective standard ligands using computational docking analysis. A pilot clinical trial was designed to investigate the safety and efficacy of Althaea officinalis in children with AD. The diagnosis of AD was made according to the criteria of Hanifin and Rajka. Children between 3 months and 12 years old were participated in this trial and randomly allocated into two parallel intervention and control groups. The intervention group used Althaea officinalis 1% ointment while the positive control group used Hydrocortisone 1% ointment twice a day for a week and after that, three times per week for a period of 3 weeks. The severity of AD was measured using the SCORAD score at the end of each assessment visits. A total number of 22 patients completed the study. A significant decrease of the SCORAD score was observed in both groups. At the end of the study, this score change, which indicates the improvement of the patients was significantly higher in the intervention group in comparison to the baseline (p-value = .015) and week 1 (p-value = .018). In the docking analysis of the study, 33 phytochemical compounds were identified, which were docked into the active site of IL6, TNF-alpha, and human PDE4 isoenzymes. Affinity toward the selected enzymes was significantly higher in glycosylated compounds. The results of this pilot study showed that the efficacy of Althaea officinalis 1% ointment in a decrease of disease severity is more than Hydrocortisone 1% in children with AD. However, further studies are needed to confirm this finding. Moreover, the docking analysis revealed that the inhibitory activity of compounds with free hydroxyl groups such as glycosylated compounds was better than others, probably due to the hydrogen bond interaction of hydroxyl groups of the ligands with the enzymes.

Speech-evoked auditory brainstem response; electrophysiological evidence of upper brainstem facilitative role on sound lateralization in noise.

BACKGROUND AND AIM: Sound lateralization/localization is one of the most important auditory processing abilities, which plays approved role in auditory streaming and speech perception in challenging situations like noisy places. In addition to the main role of lower brainstem centers like superior olivary complex in sound lateralization, efferent auditory system effects on improving auditory skills in everyday auditory challenging positions were revealed. This study evaluated noise effects on lateralization scores in correlation with an objective electrophysiologic test (Speech-ABR in noise), which objectively shows cumulative effects of the afferent and efferent auditory systems at the inferior colliculus and upper brainstem pathway. METHOD: Fourteen normal-hearing subjects in the age range of 18 to 25 participated in this study. Lateralization scores in the quiet and noisy modes were evaluated. Speech-ABR in both ears for quiet mode and three different contralateral noise levels (SNR = + 5, 0, - 5) were recorded, too. Correlation of lateralization scores and Speech-ABR changes in noise was studied. RESULTS: Significant decrease of lateralization scores with latency increase and amplitude decrease of Speech-ABR transient peaks (V, A, O) was seen with noise presentation. A high positive correlation between lateralization decrease with latency increase of onset peaks (V, A) and amplitude decrease of transient peaks (V, A, O) was found in low signal-to-noise ratios. CONCLUSION: The study revealed that in high challenging auditory situations like auditory lateralization in noise, upper brainstem centers and pathways play a facilitative role for main auditory lateralization centers in lower levels.

In vitro and in vivo effects of chitosan-praziquantel and chitosan-albendazole nanoparticles on Echinococcus granulosus Metacestodes.

Cystic echinococcosis (CE), which is caused by the metacestode of Echinococcus granulosus, is one of the most important zoonoses affecting humans. Benzimidazoles (in particular albendazole) and praziquantel (PZQ) are effective against CE, but poor water solubility of these agents often leads to inadequate results. Here, we evaluate the effects of chitosan-albendazole (ChABZ) and chitosan-praziquantel (ChPZQ) nanoparticles as a new formulation on hydatid cysts both in vitro and in vivo. Developed microcysts in culture were treated with different concentrations of ChABZ and ChPZQ nanoparticles (either alone or in combination), and ABZ + PZQ suspension. The viability rate of microcysts was used to evaluate the drug efficacies. In addition, the prophylactic and therapeutic effects of the drugs were studied on infected DBA/2 mice. Transmission electron microscopy was used to observe the ultra-structural changes. The viability rate of microcysts and differences in cyst weights were compared by ANOVA, and the cyst numbers were compared using the Kruskal-Wallis test. The combination of ChABZ + ChPZQ nanoparticles was more effective than the ABZ + PZQ suspension in vitro (p < 0.05). In prophylaxy, a significant reduction was observed both in size and in number of the cysts in ChABZ + ChPZQ nanoparticle groups compared with the control group (p < 0.05). In the therapeutic stage, however, this treatment only reduced the cyst numbers. Degeneration of the microcysts treated with the drugs was evident in the ultra-structural imaging. Overall, the nanoparticulate drugs were more effective than their suspension counterparts, but further studies are recommended to evaluate the full potential of these nanoparticles in the treatment of human CE.

Sonographic measurement of cervical length and its relation to the onset of spontaneous labour and the mode of delivery.

Background: We aimed to investigate the relationship between cervical length at 37 weeks of pregnancy and the onset of spontaneous labour as well as mode of delivery. Methods: We did a prospective observational study of 126 low-risk pregnant women with cephalic presentation who were not in labour, attending a south Tehran health centre for prenatal care. The length of the cervix was measured using transvaginal ultrasound (10 MHz endovaginal transducer) by a single sonographer at 37 weeks of gestation. The outcomes were the onset of spontaneous labour and the mode of delivery. Results: The mean cervical length was 26.1 mm (range 10-51 mm), with a non-significant difference between nulliparous and parous women (p=0.36). There was a significant association between cervical length and onset of spontaneous labour (r=0.33, p<0.001). When controlled for parity, maternal height and onset of spontaneous labour, cervical length did not predict the mode of delivery (p=0.79). Conclusion: Measurement of cervical length at 37 weeks could predict the onset of spontaneous labour, but it failed to predict the mode of delivery.

The effect of whole-body vibration training on the lower extremity muscles' electromyographic activities in patients with knee osteoarthritis.

Background: Whole-Body Vibration Training (WBVT) is a novel neuromuscular training method that has been recently developed as a rehabilitation tool. The purpose of this study was to determine whether WBVT is effective on electromyographic activity of the muscles of the lower limbs in patients with knee osteoarthritis. Methods: The study was designed as a single blinded randomized clinical trial (IRCT201601171637N5), 45 patients with knee osteoarthritis were randomly assigned to three groups; WBVT (n = 15) receiving 12 sessions vibration therapy, control group (n =15) doing two exercise in the home and placebo (n =15) doing exercise like WBVT group on-off vibration system. Electromyographic activities of vastus lateralis and vastus medialis, semitendinosus, gastrocnemius and soleus were evaluated pre and post intervention. The pairedsamples t-test and ANOVA were applied respectively to determine the differences in each group and among the groups (P≤0.05). Results: The RMS value of vastus medialis in semi squat position in placebo group (p=0.024), vastus lateralis in SLR position in WBVT group (p=0.037), soleus in knee flexion in WBVT group (p=0.018), semitendinosus in knee flexion in WBVT group (p=0.007) and RMS response of Semitendinosus in ankle plantar flexion in control group (p=0.047) were revealed significant differences between the pre- and post- intervention. The ANOVA test confirmed the significant differences between the studied groups according to the EMG activity of vastus medialis in semi squat position (p=0.045), semitendinosus in semi squat position (p=0.046) and in plantar flexion position (p=0.015) and also soleus in plantar flexion position (p=0.003). Conclusions: The findings of this study showed the beneficial effects of WBVT in the improvement of the muscles RMS values in the patients with knee OA especially muscles' progression rates in a four-week period.

Effects of vowel auditory training on concurrent speech segregation in hearing impaired children.

OBJECTIVE: This clinical trial investigated the ability of concurrent speech segregation in hearing impaired children. The auditory behavioral responses and auditory late responses (ALRs) were compared between test and control groups prior to vowel auditory training and after 3 and 6 months of vowel auditory training to find the effects of bottom-up training on concurrent speech segregation in hearing impaired children. METHODS: Auditory behavioral responses for 5 vowels and ALRs for double synthetic vowels, with special physical properties, were recorded in a timetable in 30 hearing impaired children (test group = 15 and control group = 15). RESULTS: Identification score and reaction time data showed that the test group was approximately proficient for some vowels (P < .05 for vowels /æ/, /e/, and /u:/) and took less time to process after 6 months of training. N1-P2 amplitude indexing of the vowel change detection and reflecting central auditory speech representation without active client participation has been increased in the test group (P < .05). CONCLUSION: The present study showed training-related improvements in concurrent speech segregation. This information provided evidence for bottom-up training based on F0, its differences in auditory scene analysis, and neural underpinnings.

The prevalence of adulthood overweight and obesity in Tehran: findings from Urban HEART-2 study.

BACKGROUND: To estimate and compare prevalence of overweight and obesity among adult people across the 22 districts of Tehran in 2011. METHODS: This was a cross-sectional study using data on 47,406 women and 47,525 men aged≥ 15 years from a large population-based survey (Urban HEART-2). Age-standardized prevalence (ASP) of overweight (25≤BMI<30) and obesity (BMI≥30) were estimated for the Tehran's districts. Pearson Chi2 tests and logistic regression were used to examine any significant differences in prevalence of these disorders across sociodemographic groups. RESULTS: ASPs of overweight were 36.5% and 32.0 % among men and women, respectively (p<0.001). These figures for obesity were 10.7% and 15.3% among men and women, respectively (p<0.001). Crude prevalence of overweight and obesity rose with age up to the age of 54 years and decreased thereafter. Across education groups, the lowest prevalence of overweight/obesity was seen among most educated people. The results showed that being young, single and student were associated with lower odds of overweight/obesity. CONCLUSION: This study showed a high prevalence of overweight and obesity among adult in Tehran. There were significant associations between sociodemographic characteristics and prevalence of overweight/obesity among adults in Tehran. The results of this study might be used in identifying high risk groups of overweight and obesity in Tehran.

Different patterns of association between education and wealth with non-fatal myocardial infarction in Tehran, Iran: A population-based case-control study.

BACKGROUND: Myocardial Infarction (MI) is a main cause of death and disability worldwide, which involves a number of genetic, physiopathologic and socio-economic determinants. The aim of this study was to assess the patterns of association between education, wealth and some other risk factors with non-fatal MI in Tehran population. METHODS: Data derived from a second round of large cross-sectional study, Urban HEART-2, conducted in Tehran in 2011. Out of 118542 participants, all 249 self-reported incident cases of nonfatal MI were selected as the case group. A number of 996, matched on age and sex, were selected as controls. Principle component analysis (PCA) was used to calculate wealth index and logistic regression model to assess relations between the study variables. RESULTS: Mean (SD) age of participants was 60.25 (12.26) years. A total of 870 (69.9%) of the study subjects were men. Education, wealth status, family violence, hypertension and diabetes were observed as independent predictors of non-fatal MI. Overall, as the level of education increased, the odds of non-fatal MI decreased (p<0.001). We observed an almost J-shaped association between wealth status and non-fatal MI. No significant associations were found between marital status, BMI and current smoking with non-fatal MI (p<0.05). CONCLUSION: We found different patterns of association between education and wealth with nonfatal MI among Tehran adults. Lower risk of non-fatal MI is linked to high educated groups whereas economically moderate group has the lowest risk of non-fatal MI occurrence.

Health-related quality of life in patients with polycystic ovary syndrome (PCOS): a model-based study of predictive factors.

INTRODUCTION: Understanding the factors that contribute to health-related quality of life (HRQOL) is critical for developing the most appropriate interventions for improving or maintaining the HRQOL in polycystic ovary syndrome (PCOS) patients. AIM: This study sought to determine the most significant predictors of the HRQOL in patients with PCOS. METHODS: This was a cross-sectional study of 300 women with PCOS that was carried out in Kashan, Iran. A sample of women with PCOS was entered into the study and completed the following questionnaires: the Hospital Anxiety and Depression Scale, the Body Image Concern Inventory (BICI), the Rosenberg's Self-Esteem Scale score, the modified polycystic ovary syndrome health-related quality of life questionnaire, the Female Sexual Function Index. MAIN OUTCOME MEASURE: Both direct and indirect relationships among clinical severity, psychological status, self-esteem, body image, and sexual function as independent predictors of HRQOL were examined using structural equation modeling (SEM) analysis. By using the SEM, we simultaneously test a number of possible hypotheses concerning the interrelations among the predictors of HRQOL in PCOS patients. RESULTS: In relation with severity of PCOS, reproductive history and menstrual status explained a high proportion of the variance of clinical variables (factor loading 0.37 and 0.34, respectively). The highest effect on HRQL was exerted by indirect effect of clinical factor (ß = 0.90), self-esteem (ß = 1.12), body image (ß = 1.06), and sexual function (ß = 0.26) that influenced negatively HRQOL. The infertility and menstrual domains were the most affected areas of HRQOL. In relation with sexual dysfunction, the most affected domains were desire and arousal. CONCLUSION: The highest effect of PCOS symptoms on HRQOL impairment among patients was exerted by self-esteem, body image, and sexual dysfunction. With regard to HRQOL in clinical routine, we conclude these mediating factors should be taken into consideration and adequately treated if present.

Concurrent auditory perception difficulties in older adults with right hemisphere cerebrovascular accident.

BACKGROUND: Older adults with cerebrovascular accident (CVA) show evidence of auditory and speech perception problems. In present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds. METHODS: Concurrent auditory segregation using competing sentence test (CST) and dichotic digits test (DDT) was assessed and compared in 30 male older adults (15 normal and 15 cases with right hemisphere CVA) in the same age groups (60-75 years old). For the CST, participants were presented with target message in one ear and competing message in the other one. The task was to listen to target sentence and repeat back without attention to competing sentence. For the DDT, auditory stimuli were monosyllabic digits presented dichotically and the task was to repeat those. RESULTS: Comparing mean score of CST and DDT between CVA patients with right hemisphere impairment and normal participants showed statistically significant difference (p=0.001 for CST and p<0.0001 for DDT). CONCLUSION: The present study revealed that abnormal CST and DDT scores of participants with right hemisphere CVA could be related to concurrent segregation difficulties. These findings suggest that low level segregation mechanisms and/or high level attention mechanisms might contribute to the problems.

Prevalence and associated factors of self-reported hypertension among Tehran adults in 2011: a population-based study (Urban HEART-2).

BACKGROUND: Hypertension is an important public-health challenge worldwide. The prevalence of hypertension greatly varies across countries. The aim of this study was to estimate the prevalence of self-reported hypertension and to determine related factors in a large random sample of Tehran population in 2011. METHODS: In this cross sectional study, 69173 individuals aged 25-64 years were selected using multistage cluster random sampling method. All participants were interviewed by trained personnel using standard questionnaires. Weighted prevalence and incidence rates were calculated and principle component analysis (PCA) was used to construct wealth index. Chi-square and odds ratio were used to assess associations in univariate analysis. Logistic Regression model was used in multivariate analysis. RESULTS: The prevalence of self-reported hypertension was 5.27% in total, 3.83% in men and 6.64% in women (p< 0.001). The annual incidence rate of self-reported hypertension was 6.87 per 1000; 5.26 in men and 8.43 in women (p< 0.001), obviously varied across various districts. In multivariate analysis, age, sex (woman), marital status (single), obesity and smoking were positively associated with prevalence of self-reported hypertension. Education level was negatively associated to hypertension. On the other hand, wealth status was not associated to self-reported hypertension. CONCLUSION: Our study findings highlighted low awareness rates of hypertension among Tehran adults especially in men and younger people. Hence, we recommend public health strategies to improve health education programs. Moreover, programs to develop the surveillance system and screening programs to early detection of undiagnosed cases are urgently needed particularly in high risk population subgroups.

Psychological investigation in patients with polycystic ovary syndrome.

BACKGROUND: The aim of the present study was to estimate the prevalence of mood disorders and examine a range of predictors for psychological well-being among Iranian women with polycystic ovary syndrome (PCOS). METHODS: A cross-sectional study was undertaken to ascertain the factors related to psychological distress in PCOS patients in Kashan, Iran. Psychological distress was measured using the Hospital Anxiety and Depression Scale (HADS). In addition we assessed quality of life using the Short Form Health Survey (SF-36). Socio-demographic details and clinical information of PCOS including obesity (body mass index), excessive body hair (hirsutism score), acne, menstrual cycle disturbances, infertility and endocrine profile also were recorded for each patient. RESULTS: In all 300 women with PCOS were entered into the study. Of these 32% (n =96) showed elevated HADS anxiety while depression was high in 5% (n =15). Quality of life was significantly impaired in women with anxiety (P <0.05), and depression (P <0.001) and in particular, in women with coexistence anxiety and depression (P <0.001) compared with unaffected participants. Compared with the non-depressed PCOS patients, the depressed women had significantly higher menstrual irregularities (P = 0.008). Moreover, we found significant difference in FAI level between the depressed and non depressed (p = 0.05), the anxious and non anxious patients (p < 0.001) compare to non affected PCOS women. CONCLUSIONS: The high prevalence of depression and anxiety in this population suggests that initial evaluation of all women with PCOS should also include assessment of mental health disorders. The clinician should further pay attention to background of their patients especially in view of the factors influencing psychological well-being.

A clinicopathological approach to sulfur mustard-induced organ complications: a major review.

CONTEXT: Sulfur mustard (SM), with an old manufacturing history still remains as potential threat due to easy production and extensive effects. OBJECTIVES: Increasing studies on SM indicates the interest of researchers to this subject. Almost all human body organs are at risk for complications of SM. This study offers organ-by-organ information on the effects of SM in animals and humans. METHODS: The data sources were literature reviews since 1919 as well as our studies during the Iraq-Iran war. The search items were SM and its all other nomenclatures in relation to, in vivo, in vitro, humans, animals, eye, ocular, ophthalmic, lungs, pulmonary, skin, cutaneous, organs and systemic. Amongst more than 1890 SM-related articles, 257 more relevant clinicopathologic papers were selected for this review. RESULTS: SM induces a vast range of damages in nearly all organs. Acute SM intoxication warrants immediate approach. Among chronic lesions, delayed keratitis and blindness, bronchiolitis obliterans and respiratory distress, skin pruritus, dryness and cancers are the most commonly observed clinical sequelae. CONCLUSION: Ocular involvements in a number of patients progress toward a severe, rapid onset form of keratitis. Progressive deterioration of respiratory tract leads to "mustard lung". Skin problems continue as chronic frustrating pruritus on old scars with susceptibility to skin cancers. Due to the multiple acute and chronic morbidities created by SM exposure, uses of multiple drugs by several routes of administrations are warranted.

Response-oriented measuring inequalities in Tehran: second round of UrbanHealth Equity Assessment and Response Tool (Urban HEART-2), concepts and framework.

BACKGROUND: Current evidence consistently confirm inequalities in health status among socioeconomic none, gender,ethnicity, geographical area and other social determinants of health (SDH), which adversely influence health ofthe population. SDH refer to a wide range of factors not limited to social component, but also involve economic, cultural,educational, political or environmental problems. Measuring inequalities, improving daily living conditions, andtackling inequitable distribution of resources are highly recommended by international SDH commissioners in recentyears to 'close the gaps within a generation'. To measure inequalities in socio-economic determinants and core healthindicators in Tehran, the second round of Urban Health Equity Assessment and Response Tool (Urban HEART-2)was conducted in November 2011, within the main framework of WHO Centre for Health Development (Kobe Centre). METHOD: For 'assessment' part of the project, 65 indicators in six policy domains namely 'physical and infrastructure','human and social', 'economic', 'governance', 'health and nutrition', and also 'cultural' domain were targetedeither through a population based survey or using routine system. Survey was conducted in a multistage random sampling,disaggregated to 22 districts and 368 neighborhoods of Tehran, where data of almost 35000 households(118000 individuals) were collected. For 'response' part of the project, widespread community based development(CBD) projects were organized in all 368 neighborhoods, which are being undertaken throughout 2013. CONCLUSION: Following the first round of Urban HEART project in 2008, the second round was conducted to trackchanges over time, to institutionalize inequality assessment within the local government, to build up community participationin 'assessment' and 'response' parts of the project, and to implement appropriate and evidence-based actionsto reduce health inequalities within all neighborhoods of Tehran.

Psychometric properties of the Iranian version of modified polycystic ovary syndrome health-related quality-of-life questionnaire.

STUDY QUESTION: Can the modified polycystic ovary syndrome health-related quality-of-life questionnaire (MPCOSQ) be validated in Iranian patients with polycystic ovary syndrome (PCOS) to provide an instrument for future outcome studies in these patients? SUMMARY ANSWER: We show initial reliability and validity of the Iranian version of the MPCOSQ as a specific instrument to measure health-related quality of life (QOL) in patients with PCOS in Iran. WHAT IS KNOWN ALREADY: The prevalence of PCOS in Iran is relatively high and studying QOL in these patients is important. The PCOSQ has previously been translated and validated in Iran but no studies had examined the psychometric properties of the MPCOSQ in Iran. STUDY DESIGN, SIZE, AND DURATION: This was a cross-sectional study. After linguistic validation of the Iranian version of MPCOSQ, an expert panel evaluated the items by assessing the content validity index (CVI) and content validity ratio (CVR). Then a semi-structured interview was conducted to assess face validity. Consequently, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to indicate the scale constructs (n = 200). In addition, reliability analyses including internal consistency and test-retest analysis were carried out. PARTICIPANTS/MATERIALS, SETTING, AND METHODS: This study was carried out on women with PCOS (n = 200) who attended two private gynecology clinics in Kashan, Iran. Patients were eligible if they met each of the following criteria: 15-40 years of age; married; not having non-classic adrenal hyperplasia, thyroid dysfunction and hyperprolactinemia; Iranian; not having problems in speaking or listening; having two of the following Rotterdam diagnostic criteria: (i) polycystic ovaries visualized on ultrasound scan (presence of 12 follicles or more in one or both ovaries and/or increased ovarian volume >10 ml), (ii) clinical signs of hyperandrogenism (the hirsutism score based on the Ferriman-Gallwey score >7 or obvious acne) and/or an elevated plasma testosterone (normal range testosterone <2 nmol/l), (iii) having an interval between menstrual periods >35 days and/or amenorrhea as the absence of vaginal bleeding for at least 6 months, i.e. 199 days. MAIN RESULTS AND THE ROLE OF CHANCE: CVI and CVR scores for MPCOSQ were 0.96 and 0.92, respectively. A six-factor solution (emotional disturbance, weight, infertility, acne, menstrual difficulties and hirsutism) emerged as a result of an EFA and explained 0.64% of the variance observed. The result of the EFA supported the item 'late menstrual period' being placed in the menstrual rather than the emotional subscale. The results of the CFA for six-factor model for MPCOSQ indicated an acceptable fit for the proposed model. Additional analyses indicated satisfactory results for internal consistency (Cronbach's alpha ranging from 0.76 to 0.92) and intraclass correlation coefficients (ranging from 0.71 to 0.92). Moving 'late menstrual period' from the emotional to the menstrual subscale significantly improved the reliability coefficient for both subscales. LIMITATIONS, REASONS FOR CAUTION: Study of patients with PCOS attending two private gynecology clinics may limit generalization of the findings to the entire population with PCOS. All patients in this study were married for cultural reasons in Iran. Therefore, the results of the present study have to be interpreted with some caution. WIDER IMPLICATIONS OF THE FINDINGS: The Iranian version of the MPCOSQ will fill an important gap in measuring the QOL in patients with PCOS in the research and community settings in Iran.

Serum albumin and paraoxonase activity in Iranian veterans 20 years after sulfur mustard exposure.

Sulfur mustard, a chemical warfare agent, has short- and long-term effects on various organs including respiratory system. Its late toxic effects on biological macromolecules among exposed veterans have not been well studied. We performed a study to determine paraoxonase-1 (PON1) activity and phenotype distribution as well as its correlation with albumin level in 289 male veterans with severe pulmonary complications who had exposure to sulfur mustard 20 years ago and in 66 age and ethnic matched healthy male subjects as controls. Serum albumin levels were lower in the veterans compared to controls (P < 0.001). Mean basal PON1 activity was 91.61 ± 44.80 U/mL in the veteran group versus 110.27 ± 50.23 U/mL in controls (P = 0.005). Arylesterase activity was not significantly different between the two groups. Paraoxonase to arylesterase activity ratio was significantly lower in the veterans as compared to controls (P = 0.005), mainly indicative of decreased PON1 activity rather the enzyme level. Significant reduction was found in serum albumin and PON1 activity with disease severity. Moreover, decreased high active BB (high activity) phenotype and increased intermediate active AB (moderate activity) phenotype were found in the veterans. This condition may lead to long-term accumulation of reactive oxygen metabolites resulting in a pro-oxidation milieu, which in turn can lead to increased peroxide levels and decreased antioxidant PON1 activity. In conclusion, lower serum PON1 activity and albumin might contribute to morbidity and occurrence of other complications such as atherosclerosis and rapid aging in the veterans suffering from late toxic effects of sulfur mustard.

Evaluation of the tear and serum levels of IL-8 in sulfur mustard intoxicated patients 20 years after exposure.

PURPOSE: Delayed keratitis is the most dangerous ocular complication of sulfur mustard (SM) exposure. This study aimed to evaluate the role of tear and serum levels of interleukin-8 (IL-8) in SM exposed subjects. DESIGN AND METHODS: In this historical cohort study, the experimental group included 370 participants who had been exposed to SM 20 years prior. Data were compared with those of 128 unexposed participants as the control group. After completing a thorough systemic and ocular examination, serum IL-8 levels in all exposed and controls were compared. According to the statistical calculation, tear IL-8 levels, were compared in randomly selected 48 exposed and 37 controls. Based on the ocular findings, the selected subjects were divided into two subgroups, normal subjects include those participants who had no ocular signs and abnormal subjects, were those who had at least one or more ocular signs. RESULTS: Bulbar conjunctiva and limbal tissues evaluation in all participants showed a significantly higher number of abnormalities in exposed group than in the control group (P=0.004 and P=0.048 respectively). Serum IL-8 levels in all exposed were significantly lower than the matched controls (P=0.002). Tear IL-8 levels in the selected exposed were significantly lower than in the selected controls (P=0.030). In exposed group with normal conditions of the lids, bulbar conjunctiva, cornea, tear status, limbus, slit lamp findings and final ophthalmic assessment, tear IL-8 levels were significantly lower than in the matched controls (P=0.022, 0.037, 0.027, 0.050, 0.039, 0.029, 0.045 respectively). With respect to the global ophthalmic assessment, tear fluid IL-8 levels in the abnormal controls were significantly lower than in the normal controls (P=0.049), but this decrease in secretion of tear IL-8 were not encountered in abnormal exposed (P=0.415). CONCLUSION: Tear IL-8 secretion was significantly inhibited in the unexposed controls with ocular surface abnormalities, while these inhibitory responses were not encountered in SM-exposed cases with ocular surface abnormalities.

Long-term ocular consequences of sulfur mustard in lung-injured war veterans.

PURPOSE: Ocular and pulmonary involvement are the most important complications of sulfur mustard (SM) that may happen many years after exposure. This study aims to evaluate the severity of ocular involvement and the correlation between late ocular and lung complications in patients exposed to SM. METHODS: This descriptive cross-sectional study was conducted on SM lung-injured war veterans. Status of pulmonary involvement was categorized into normal, mild, moderate, and severe based on the "Forced Expiratory Volume in first second (FEV1)".Status of ocular involvement was also categorized into normal, mild, moderate, and severe, based on the slit lamp findings. Correlation between pulmonary and ocular involvements was evaluated by Spearman rank correlation test. RESULTS: Totally, 292 war veterans with clinical pulmonary involvement were included in the study. Status of pulmonary involvement was 3.8% normal, 11.2% mild, 16.1% moderate, and 68.9% severe. Status of the ocular involvement was 68.2% normal, 13.8% mild, 5.4% moderate, and 12.6% severe. Among all patients, 96.3% had pulmonary involvement and 32.5% had ocular involvement. There was a positive correlation between the severity of ocular and pulmonary involvements (p = 0.049 and r = 0.122). CONCLUSION: The results of this study showed that although there was a positive correlation between the severity of pulmonary and ocular involvement, this correlation was weak. This might be due to the nature of the studied population or differences in the tissue susceptibilities, gas types, or exposure patterns.

Iranian nurses self-perception -- factors influencing nursing image.

AIM: The purpose of this study was to describe the perspectives of Iranian nurses regarding factors influencing nursing image. BACKGROUND: Nursing image is closely tied to the nurse's role and identity, influencing clinical performance, job satisfaction and quality of care. Images of nursing and nurses are closely linked to the cultural context in which nursing is practised, hence, this study explores how Iranian nurses perceive the factors that influence their own image. METHODS: A descriptive study using a survey design was conducted with 220 baccalaureate qualified nurses working in four teaching hospitals in an urban area of Iran. A Nursing Image Questionnaire was used and analysed using descriptive and inferential statistics. RESULTS: In the domains of 'characteristics required for entry to work', 'social role characteristics of nursing' and 'prestige, economic and social status, and self image' the nurses had negative images. 'Reward' and 'opportunity for creativity and originality' were factors that least influenced choosing nursing as a career. The presence of a nurse in the family and working in the hospital had the greatest impact on the establishment of nurses' nursing image. CONCLUSION: Improving the nursing profession's prestige and social position as well as providing the opportunity for creativity and originality in nursing practice will change the self-image of Iranian nurses, facilitating effective and lasting changes in nursing's image. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers are well-placed to influence nurses' perceptions of nursing's image. Given the finding that thinking about leaving a job positively correlates with holding a negative nursing image, nurse managers need to consider how they can work effectively with their staff to enhance morale and nurses' experience of their job.
