Prevalence and correlates of child maltreatment among mothers in the Kurdistan province, Western Iran.

OBJECTIVE: Parental child maltreatment is a serious public health issue worldwide. As mothers take on a significant proportion of parenting duties in two-parent families, knowledge of maternal risk factors for child maltreatment is essential. METHODS: In this cross-sectional study, 135 mothers with their last child under 18 years in Kurdistan province were enrolled. A validated Persian version of the ISPCAN Child Abuse Screening Tool-Parent version, Beck Anxiety Inventory, and Beck Depression Inventory were administered. RESULTS: The prevalence of severe and moderate physical punishment was 78.5% and 71.9%, respectively. Psychological punishment was reported by 99.3% of respondents, and 48.9% reported neglect. A relationship was found between child physical and emotional abuse and low maternal education (p < 0.01), domestic violence (p = 0.02), maternal exposure to maltreatment during childhood (p = 0.03), maternal depression (p < 0.01), and maternal anxiety (p < 0.01). A relationship was also found between child neglect and residence in rural areas (p < 0.01), domestic violence, and low maternal education (p = 0.02). CONCLUSION: Maternal child maltreatment in Iran is increased in mothers with psychological disorders and those with certain demographic characteristics. Clinicians should be alert to these potential risk factors.

Comparing the quality of life of endometriotic patients' before and after treatment with normal and infertile patients based on the EHP30 questionnaire.

OBJECTIVE: This study aimed to determine the quality of life (QOL), in patients with endometriosis ± infertility (B and C groups) and compare those to healthy women, and also infertile groups without endometriosis as a control groups (A and D), considering the fact that endometriosis and infertility reduces the quality of life in patients. METHODS: The present prospective comparative study was carried out between January 2018 and September 2020. A total of 400 women were included (100 women in each group). The participants filled in a validated questionnaire of quality of life, Endometriosis Health Profile-30 (EHP-30), and a visual analog scale of pain used, at the first visit, and 3 months after the medical or surgical treatment in the endometriosis group without infertility, additionally. RESULTS: The majority of the patients were married, categorized in the middle-class of socio-economic state and housewives. They were of Persian descent. BMI was high in the infertile groups; however, the time of infertility was not different between the two groups of B and C (P = 0.054). The mean score of QOL was significantly lower in B, C, and D groups in comparison to the healthy women as the control group (A) (P < 0.001). Moreover, the infertile group (B), in comparison to endometriosis ± infertility groups (C and D), had the lowest mean score of QOL (P < 0.001). In each group, those who were older and had better educational level reported a better quality of life than other participants in that group. Social support plays a very important role in reducing the endometriosis related pain symptoms both before and after treatment. Three months after the treatment of endometriosis (D), a significant improvement was observed in all the aspects of QOL-related endometriosis. Nonetheless, the improvement of the quality of life in the surgical group was significantly higher than that in the medical treatment. The mean visual analog score of pain decreased from 62.22 ± 22.78, to 5.15 ± 2.73 following the surgical treatment (P < 0.001). CONCLUSION: The lowest quality of life belonged to the infertile group, followed by the endometriosis group. The quality of life of the endometriosis group improved after the treatment. Thus, endometriotic patients' treatment in terms of improvement of quality of life should be considered by all professional health care teams.

Association between multiple sclerosis and dietary patterns based on the traditional concept of food nature: a case-control study in Iran.

INTRODUCTION: It remains a matter of debate whether traditional concepts regarding the nature of food affect the development and progression of multiple sclerosis (MS).To date, there are limited studies that have investigated the association between MS and dietary patterns based on the categories of food nature (hot, cold, or balanced) defined in traditional medicine. METHOD: This case-control study was conducted from October 2019 to February 2020. In total, 60 patients diagnosed with MS within the preceding 6 months and referred to our neurology outpatient clinic were included in our case group. The control group included 180 patients who were referred to the same center for general or orthopedic surgery. Dietary intake was assessed in both groups through a reliable and valid semi-quantitative food frequency questionnaire. Data were assessed using principal component analysis. RESULTS: The mean age of the participants was 44.9 ± 17.33 years. The analysis showed that four food patterns were distinguished (eigenvalue > 1), namely "additives and cold-natured foods", "hot and balanced foods and nuts", "dairy and legumes", and "hot and balanced starches". These food patterns explained 57.8% of the total variance. After adjusting all confounding factors, individuals in the highest quartile and medium quartile of "additives and cold-natured foods" had an elevated MS risk compared with the lowest quartile (OR = 7.21, 95%CI = 2.01-12.38 and OR = 3.37, 95%CI = 1.02-11.35, respectively). Furthermore, individuals in the highest quartile of the "hot and balanced foods and nuts" group were protected against MS compared with its lowest quartile (OR = 0.28, 95%CI = 0.08-0.90). Moreover, a protective effect against MS was seen in the highest quartile of the "hot and balanced starches" group relative to its lowest quartile (OR = 0.34, 95%CI = 0.12-0.98). No significant association was found between "dairy and legumes" and the risk of MS. CONCLUSION: This study revealed that dietary patterns based on the traditional concept of food nature might be associated with the risk of developing MS. This represents the first work in this area, so further research is recommended.

Effect of temperature and humidity on the sensing performance of TiO2nanowire-based ethanol vapor sensors.

In this paper, we study the influence of two key factors, temperature, and humidity, on gas sensors based on titanium dioxide nanowires synthesized at 4 different temperatures and with different morphology. The samples' structure are investigated using SEM, XRD and FTIR analysis. The effects of humidity and temperature are studied by measuring the resistance and gas response when exposed to ethanol. At room temperature, we observed a 15% sensitivity response to 100 ppm of ethanol vapor and by increasing the operating temperature up to 180 °C, the response is enhanced by two orders of magnitude. The best operating temperature for the highest gas response is found to be around 180 °C. Also, it was observed that every nanowire morphology has its own optimum operating temperature. The resistance of sensors is increased at higher Relative Humidity (RH). Besides, the response to ethanol vapor experiences a gradual increase when the RH rises from 10% to 60%. On the other hand, from 60% to 90% RH the gas response decreases gradually due to different mechanisms of interaction of the TiO2with H2O and ethanol molecules.

Effect of COVID-19 on Kawasaki Disease: Decrease Age of Onset and Increase Skin Manifestation.

BACKGROUND: Kawasaki Disease (KD) is the most common childhood vasculitis and cause of acquired heart disease for no apparent reason. There is some evidence indicating infectious agents as possible triggers for KD. During the COVID-19 pandemic, vasculitis has been a presentation of COVID-19 in children. We performed this study to assess the association between KD and COVID-19. We evaluated KD hospitalized children during February to September 2020 for COVID-19 (group one) and compared their demographic, clinical, laboratory, and echocardiographic findings with KD patients from the same period time in 2019 (group two). We also compared the same data in COVID-19 positive and COVID-19 negative KD patients in 2020 pandemic period in Shiraz Namazi referral hospital at southwest of Iran. RESULTS: Thirty-two patients in group one compared with 44 patients in group two. Sixty-eight percent of group one KD patients were positive for COVID-19 during the pandemic period. KD Age of onset in the group one was lower than group two (4.38 years VS 5.5 years, P-value = 0.044). There was no difference in the demographic, clinical, laboratory, and echocardiographic features of the patients during and before the COVID-19 pandemic (p-value > 0.05). Moreover, Comparing COVID-19 positive and negative the incidence of rash was higher within COVID-19 positive cases (p < 0.05), and coronary artery abnormalities were more prevalent in COVID-19 negative cases (p < 0.05). CONCLUSION: Admission rate of KD was almost similar during the COVID-19 pandemic but 68% of KD admitted patient were COVID-19 positive. Age of onset for KD during the COVID-19 pandemic was lower and skin manifestation was higher than the same period time in last year.

EVALUATION OF THE EFFECT OF TOPICAL INTERFERON α2b AS A COMPLEMENTARY TREATMENT OF MACULAR EDEMA OF PATIENTS WITH DIABETIC RETINOPATHY: A Double-Blind Placebo-Controlled Randomized Clinical Trial Study.

PURPOSE: The objective of this study is to evaluate the effect of the topical interferon α2b (IFNα2b) as an adjunctive therapy in the treatment of diabetic macular edema. METHOD: This was a randomized controlled clinical trial performed on patients with diabetic macular edema. Fifty eyes of 50 patients (one eye/patient) who were receiving treatment for diabetic macular edema were randomly assigned to get topical IFNα2b 1 MU/mL or artificial tear eye drop as an adjunctive therapy. The primary measure outcomes were best-corrected visual acuity and central macular thickness; the secondary goals were to assess the effect of topical IFNα2b on the intraocular pressure and its potential side effects. RESULTS: Baseline demographic data of the two groups were similar. The improvement in visual acuity of patients on IFN was more than the patients on artificial tear by the end of the fourth week (6.85 and 1.45 Early Treatment Diabetic Retinopathy Study letters, respectively, P = 0.001) and the eighth week (6.75 and 1.05 Early Treatment Diabetic Retinopathy Study letters, respectively, P = 0.005). The central macular thickness was also decreased correspondingly by the end of fourth week (53.1 ± 153 µm for patients on IFN and 26.6 ± 119.1 µm for patients on artificial tear, P = 0.497) and eighth week (27.9 ± 67.7 for patients on IFN and 29.2 ± 98 µm for patients on artificial tear, P = 0.957), but it was not statistically significant. Intraocular pressure was decreased on the fourth week in IFN group for 1.7 mmHg ±3 and increased for 0.1 mmHg ±2.3 in the artificial tear group (P = 0.018). No significant side effect was detected with topical IFN drop. CONCLUSION: This study evaluated the short-term effects of topical IFNα2b 1 MU/mL. The drug was well tolerated and may have an effect on improvement of best-corrected visual acuity in patients with diabetic macular edema. It also had an intraocular pressure lowering effect on the studied eyes. However, further studies are needed to confirm this finding.

Quality of Life Assessment in Patients with Behçet's Disease using the Persian Version of the Leeds BD-QoL Questionnaire.

BACKGROUND: Behçet's disease (BD) can negatively impact the quality of life (QoL) of the affected patients. The present study aimed to assess the QoL of BD patients using the Leeds BD-QoL and compare its results with the WHOQOL-BREF questionnaire. METHODS: In the present cross-sectional study, 179 BD patients and 304 healthy individuals (the control group) were recruited in Shiraz, 2017. The Persian version of the Leeds BD-QoL and WHOQOL-BREF questionnaires were used to assess the QoL of patients with BD. The QoL in the patient and control groups was compared after controlling the effect of some variables (age, sex, marital status, and educational level) using the multiple linear regression analysis. Spearman's correlation coefficient was calculated for the Leeds BD-QoL and WHOQOL-BREF scores. Disease activity was measured using the Behçet's Disease Current Activity Form. All the statistical analysis was performed using SPSS software (version 21.0). P<0.05 was considered statistically significant. RESULTS: The mean of the Leeds BD-QoL total score in the patient group was 12.3±8.7. The control group had significantly higher scores in the WHOQOL-BREF total score and the physical health and psychological health domains compared with the patient group; mean difference of 10.24, 10.8, and 4.62, respectively (P<0.001). The Spearman's correlation coefficient for the Leeds BD-QoL score and WHOQOL-BREF total score and its domains (physical health, psychological health, social relationships, and environment) was -0.669, -0.713, -0.714, -0.536, and -0.550, respectively. The disease activity score was correlated with the Leeds BD-QoL score (r=0.361, P<0.001). CONCLUSION: BD patients had a lower QoL than healthy individuals, specifically in the physical health and psychological health domains. An increase in disease activity and severity was associated with a reduced QoL. The Persian version of the Leeds BD-QoL questionnaire had an acceptable correlation with the WHOQOL-BREF questionnaire.

Early, delayed, and expanded intracranial hemorrhage in cerebral venous thrombosis.

OBJECTIVES: One of the most important prognostic factors of cerebral venous sinus thrombosis (CVST) is intracranial hemorrhage (ICH). We studied the risk factors, clinical, and radiologic characteristics of early, delayed, and expanded ICH in Iranian patients with CVST. MATERIALS AND METHODS: In a retrospective study, from August 2012 to September 2016, all adult patients with a confirmed diagnosis of CVST were recruited. Demographic, clinical, and radiologic characteristics of the patients were recorded. The predictors of early, delayed, and expanded ICH were assessed through logistic regression analysis. RESULTS: Among 174 eligible patients, 35.1% of the patients had early ICH. Delayed and expanded hemorrhage occurred in 5% and 7.4% of the patients, respectively. Higher age was a risk factor (odds ratio [OR] = 1.038, 95% confidence interval [CI] = 1.008-1.069), and involvement of multiple sinuses/veins was associated with lower risk of early ICH (OR = 0.432, CI = 0.226-0.827). The risk of delayed ICH was higher in the patients with early hemorrhage (OR = 4.44, CI: 0.990-19.94), men (OR = 4.18, CI: 0.919-19.05), and those with a focal neurologic deficit on admission (OR = 16.05, CI: 1.82-141.39). Acute onset was the predictor of the expansion of early ICH (OR = 8.92, CI: 1.81-43.77), whereas female gender-related conditions were associated with a lower risk of hemorrhage expansion (OR = 0.138, CI: 0.025-0.770). Administration of anticoagulants was associated with neither delayed (P value = .140) nor expanded hemorrhage (P-value = .623). CONCLUSIONS: Male gender, early hemorrhages, acute onset, and presence of focal neurologic deficit are the risk factors for delayed and/or expanded hemorrhages in the patients with CVST.

One decade distinct features, morbidity and mortality of scleroderma: a cross-sectional study.

OBJECTIVES: Conducting an epidemiologic study on scleroderma patients referred to hospitals and tertiary centres of rheumatologic diseases in Shiraz, located in south of Iran. METHODS: A cross-sectional study was done on patients' records registered in scleroderma outpatient clinics as well as hospitals associated with Shiraz University of Medical Sciences. Gathering data in pre-formed data sheets, descriptive analysis plus qualitative comparisons by chi-square test were done using SPSS 15. RESULTS: In 533 medical records, female to male ratio was 7.3:1. The disease is mostly seen in 3rd and 4th decades of life. More patients had negative family histories (56.1%). 37.5% of the patients had diffuse form of the disease, 36.8% had limited one, and 17.3% had overlap syndrome, mostly, by lupus erythematosus (33%). Most common first presentation was Raynaud phenomenon (40.7%). Two most prevalent clinical manifestations were skin thickening (97.2%) and gastrointestinal involvement (68.9%). Clinical presentations were compared between three most common types of the disease plus various stages of life. Among recorded capillaroscopies, active form was the most prevalent one (38.3%). In documented serologic markers, the most common positive one was anti-nuclear antibody (ANA) (75.6%). Two most common etiologies of hospitalisation were digital ulcer (30.9%) and pulmonary fibrosis (5.7%). The most common cause of death (17) was pulmonary fibrosis (35.2%). CONCLUSION: This study is the first epidemiologic survey on Iranian scleroderma patients with significantly large sample size compared to previous studies worldwide. It can thus provide some guidance for further multi-provincial, multinational and interracial studies on scleroderma.

Acupuncture for treating hot flashes in breast cancer patients: an updated meta-analysis.

PURPOSE: The aim of this study was to evaluate the effectiveness of acupuncture for treatment of hot flash in women with breast cancer. METHODS: The aspects considered in this study included searching for 12 data bases until April 2015 and consulting reference lists of reviews and related articles. Additional features studied comprised all articles on human patients with breast cancer treated with needle acupuncture with or without electrical stimulation for the treatment of hot flashes. The methodological quality was assessed using the modified Jadad score. RESULT: The searches identified 12 relevant articles for inclusion. The meta-analysis without any subgroup or moderator failed to show favorable effects of acupuncture on reducing the frequency of hot flashes after intervention (n = 680, SMD = - 0.478, 95 % CI -0.397 to 0.241, P = 0.632) but exhibited marked heterogeneity of the results (Q value = 83.200, P = 0.000, I^2 = 83.17, τ^2 = 0.310). CONCLUSION: The meta-analysis used had contradictory results and yielded no convincing evidence to suggest that acupuncture was an effective treatment of hot flash in patients with breast cancer. Multi-central studies including large sample size are required to investigate the efficiency of acupuncture for treating hot flash in patients with breast cancer.

Anesthesia and Pain Relief in the History of Islamic Medicine.

BACKGROUND: Since diseases and surgeries could be very painful, the annihilation of pain has been the most important goal of physicians. The history of Iranian-Islamic medicine includes distinguished physicians that attempted to find different methods of anesthesia. This research aims at reviewing approaches for anesthesia throughout the history of the Iranian-Islamic medicine, in order to identify a variety of drugs used during that period. METHODS: In this research, the information was mainly collected from medical history, traditional literature and various search engines (e.g. Google Scholar, PubMed, Medline, Scopus, SIDS and NoorMags). The search keywords were Anesthetic, Tbnj (sedation), Tnvym (sedative), and Hypnotic. Finally, a detailed analytical study was performed on all notes and the results were presented. RESULTS: Mohammad Ibn-Zakaria Al-Razi (known to the Western world as Razes) in the 10th century was the first physician who used general inhalation for anesthesia in surgeries. Drugs used to relieve pain and anesthesia can be divided into two categories: (i) single drug and (ii) compound drugs. Usually, these are consumed by eating, drinking, inhalation, or as topical. Drugs such as Hemlock, Mandrake, Henbane, Hyocyamus, Mandragora, Loiseuria, Opium Poppy, and Black Nightshade were used. Beyond these herbs, Aghili (18th century) in his book "Makhzan al-adviyah" also explained the topical application of ice for pain management. The choice for the type of medication and its form of consumption is commensurate to pain and the speed by which the drug has an effect. Anesthesia was usually done in two ways: (i) using a substance called "Mokhader" which was consumed via the mouth or nose, and (ii) "Tnvym" which means putting a patient to sleep to block the sensation of pain. Typically, anesthesia methods and drug recipes were kept as secret to prevent misuse and abuse by unauthorized people. CONCLUSION: Based on our study, Islamic physicians proposed inspiring methods in using drugs for anesthesia, which in turn greatly contributed to the Iranian-Islamic civilization.

The Prevalence of Complementary and Alternative Medicine Use among Dermatologic Outpatients in Shiraz, Iran.

BACKGROUND: The use of complementary and alternative medicine (CAM) has been increasing among patients worldwide. The objective of this study was to assess CAM use and its related factors among Iranian dermatologic outpatients in Shiraz, Iran. METHODS: This cross-sectional study was conducted in Shiraz, Iran. Six hundred dermatologic outpatients were randomly selected. We used a self-structured questionnaire with 14 items to assess CAM use and its related factors among our participants. We used descriptive statistics reported as mean±SD and frequency by Mann-Whitney U test, chi square and binary logistic regression tests for statistical analysis. RESULTS: Among the 600 participants, 188 (31.3%) had used one of the CAM methods for resolving their dermatologic problems. The most frequent method used was herbal medicine (89.9%). The mean age and years of duration of the skin condition were significantly higher in patients using CAM compared to non-users (P=0.001 and 0.037, respectively). Patients with acne, alopecia, and hair loss significantly used CAM more than other diseases (OR: 2.48, CI 95%: 1.28-4.78) and (OR: 3.19, CI 95%: 1.62-6.27), respectively. There was a significant relationship between education and using CAM (P<0.001). CONCLUSION: Community member's behavior in CAM use without adequate knowledge may have a noticeable influence on each other. Since it is a prevalent matter, we should think of ways of educating the general population about CAM methods and its potential risks and benefits. We also should encourage our healthcare workers to communicate such materials with their patients.

The Relationship between Body Mass Index and Temperament, Based on the Knowledge of Traditional Persian Medicine.

BACKGROUND: Temperament is one of the key concepts in traditional Persian medicine (TPM), which is the quality that will be obtained by the reaction between the four elements of water, earth, fire and air, and its property is different from the component property. According to TPM, temperament is influenced by many factors and the bulk of the body is one of these factors. In this study, we aimed at determining the relationship between person's temperament based on the knowledge of TPM and the body mass index (BMI). METHODS: This study is a cross-sectional study that examines the relationship between person's temperament and their BMI. For this purpose, 86 employees (20-40 years) of Shiraz Medical School were selected and their temperaments assessed using Dr. Mojahedi's temperament questionnaire and visitation by a TPM specialist. SPSS 18 was used for statistical analysis. RESULTS: In this study, 86 employees were evaluated including 18 (20.9%) male and 68 (79.1%) female. The mean age of the participants was 32.45±4.93 years old and the mean BMI was 23.75±2.94. Minimum and maximum BMI were related to people with temperament of cold and dry and cool temperament and more with the mean of 20.55±1.90 and 28.13±0.35, where the difference was statistically significant (P=0.0003). BMI in people with a temperament of hot and dry was significantly less than those with cool and wet temperament (P=0.01). CONCLUSION: Based on TPM, people with wet temperament are usually more obese and people with dry temperament are thinner. The results of this study confirm that obese people are cold and wet or have phlegmatic temperament whereas in comparison thin people are drier. This is in-line with the principles of TPM.

Efficacy of Nepeta Menthoides Boiss and Buhse Freeze-Dried Aqueous Extract on Anxiety of Patients with Depression: A Double-Blind Randomized Controlled Clinical Trial.

BACKGROUND: The efficacy and safety of Nepeta menthoides freeze-dried aqueous extract were assessed on the anxiety of patients suffering from depression. METHOD: Patients received either N. menthoides formulation (400 mg/BID) or Sertraline (50 mg/BID) for 4 weeks. The Beck Anxiety Inventory (BAI) scales were used to assess the anxiety in two-week intervals (2nd, 4th, and 6th weeks). Folin-Ciocalteu and Dowd methods were used to determine the formulation of total phenol and flavonoid contents. RESULTS: Compared with Sertraline, N. menthoides showed a higher reduction in BAI scores in the 2nd (16.52±8.07 vs. 21.38±10.98, P<0.05) and 4th week (11.55±6.74 vs. 20.47±11.53, P<0.05) along with a reduction in the recurrence rate and side effects. Total phenolic and flavonoid contents revealed in the presence of 127.09±0.43 mg GAE/g and 16.93±0.09 mg Q/g of extract. CONCLUSION: N. menthoides could be effective in the control and introducing a delay in recurrence of anxiety in patients with depression.

Early Acute Kidney Injury based on Serum Creatinine or Cystatin C in Intensive Care Unit after Major Trauma.

BACKGROUND: Acute kidney injury (AKI) is a common problem in critically ill patients and is independently associated with increased morbidity and mortality. Recently, serum cystatin C has been shown to be superior to creatinine in early detection of renal function impairment. We compared estimated GFR based on serum cystatin C with estimated GFR based on serum creatinine for early detection of renal dysfunction according to the RIFLE criteria. METHODS: During 9 months, three hundred post trauma patients that were referred to the intensive care unit of a referral trauma hospital were recruited. Serum creatinine and serum cystatin C were measured and the estimated GFR within 24 hours of ICU admission was calculated. The primary outcome was the incidence of AKI according to the RIFLE criteria within 2(nd) to 7(th) day of admission. RESULTS: During the first week of ICU admission, 21% of patients experienced AKI. After adjusting for major confounders, only the patients with first day's serum cystatin level higher than 0.78 mg/l were at higher risk of first week AKI (OR=6.14, 95% CI: 2.5-14.7, P<0.001). First day's serum cystatin C and injury severity score were the major risk factors for ICU mortality (OR=3.54, 95% CI: 1.7-7.4, P=0.001) and (OR=4.6, 95% CI: 1.5-14, P=0.007), respectively. CONCLUSION: Within 24 hours after admission in ICU due to multiple trauma, high serum cystatin C level may have prognostic value in predicting early AKI and mortality during ICU admission. However, such correlation was not seen neither with creatinine nor cystatin C based GFR.

Healing effect of sea buckthorn, olive oil, and their mixture on full-thickness burn wounds.

OBJECTIVE: The purpose of this study is to evaluate the healing effect of silver sulfadiazine (SSD), sea buckthorn, olive oil, and 5% sea buckthorn and olive oil mixture on full-thickness burn wounds with respect to both gross and histopathologic features. METHODS: Full-thickness burns were induced on 60 rats; the rats were then were divided into 5 groups and treated with sea buckthorn, olive oil, a 5% sea buckthorn/olive oil mixture, SSD, and normal saline (control). They were observed for 28 days, and the wounds' healing process was evaluated. RESULTS: Wound contraction occurred faster in sea buckthorn, olive oil, and the sea buckthorn/olive oil mixture groups compared with the SSD and control groups. The volume of the exudates was controlled more effectively in wounds treated with the sea buckthorn/olive oil mixture. Purulent exudates were observed in the control group, but the others did not show infection. The group treated with sea buckthorn/olive oil mixture revealed more developed re-epithelialization with continuous basement membrane with a mature granulation tissue, whereas the SSD-treated group showed ulceration, necrosis, and immature granulation. The results show that sea buckthorn and olive oil individually are proper dressing for burn wounds and that they also show a synergetic effect when they are used together. CONCLUSION: A sea buckthorn and olive oil mixture could be considered as an alternative dressing for full-thickness burns because of improved wound healing characteristics and antibacterial property.

Structural validity of the Pittsburgh Sleep Quality Index among medical students in Iran.

The Pittsburgh Sleep Quality Index (PSQI) is a self-reported questionnaire evaluating sleep quality based on seven domains of sleep disorders. However, the factor structure of PSQI needs to be well-established among medical students. This study was conducted to establish the factor structure of PSQI among medical students. Four-hundred and four medical students completed the PSQI. Considering each PSQI component as an "observed variable," exploratory factor analysis was conducted. Six models explaining the factor structure of PSQI were compared by confirmatory factor analysis to achieve the best model. All PSQI components were loaded on three factors. The first factor included sleep duration and habitual sleep efficiency, the second was subjective sleep quality and sleep latency, and the third was sleep disturbances, sleeping medications, and daytime dysfunction (root mean square error of approximation = < 0.01, goodness of fit index = 0.99). The differences in Bayesian information criteria and root mean square error of approximation between our best-fit model and each of the other resulted in rejection of all other Models. Besides confirming the structural validity among medical students, our findings indicated the adequacy of the 3-factor structure of PSQI, including sleep efficiency, perceived sleep quality, and daily disturbances in this population.

A symptom profile analysis of depression in a sample of Iranian patients.

BACKGROUND: In some cultures, including ours, direct explanation of inner psychic world is inhibited and stigmatized, therefore finding alternative modes of expression. The aim of this cross-sectional study was to assess the frequency of somatization in the depressed patients. METHODS: The present study comprised 500 patients referred to the outpatient clinic of Shiraz University of Medical Sciences, and diagnosed with major depressive disorders based on DSM-IV-TR. The presenting complaints of these patients were assessed through psychiatric interview. The presenting symptoms were divided into three main categories including mental symptoms, pain, and physical symptoms without pain. Statistical analysis (chi-square and logistic regression) were performed to determine the relationship between presenting symptoms and some demographic variables such as age, gender, marital status, educational level and cultural background (urban or rural). RESULTS: Physical symptoms other than pain, mental symptoms, and pain were found in 193 (38.6%), 186 (37.2%), and in 121 (24.2%) patients respectively. Pain and physical complaints were more common in patients with rural cultural background, lower education, women and the married individuals. Headache (15.2%), irritability (10.6%) and pain in different parts of the body (10.4%) were the most frequent chief complaints of the patients. Hypochondriasis, suicidal idea, crying, irritability and insomnia were significant symptoms associated with the complaint of somatization. CONCLUSION: Somatic symptoms, especially pain, have a significant weight in the chief complaints of depressed patients. Physicians need to pay particular attention to this important issue in order to better understand these patients.

Sustained Elimination of Iodine Deficiency Within the Third Decade After Compulsory Iodine Supplementation Policy in the South of Iran: A Population-Based Cross-Sectional Study.

Objectives: Recently, some studies in Iran have shown mild to moderate iodine concentrations in adult and pregnant women populations despite iodine sufficiency in children. This study aimed to evaluate the urine iodine status and salt intake among adult households in the city of Sadra, Fars province in southern Iran, and to assess its possible influencing factors. Method: Participant households for this cross-sectional study were selected using randomized cluster sampling in the city of Sadra, Fars province, southern Iran from 1 February, 2021 to 30 November, 2021. Two subjects >18 y of age from each household were invited. Ninety-two subjects (24 men, 68 women) were enrolled. The participants were asked to collect their 24 h urine. They were then examined for thyroid disorders and subjected to thyroid ultrasonography and thyroid function tests. Urine samples were tested for iodine, sodium, and creatinine concentrations. Household salt intake was also estimated. Results: Median urine iodine content (UIC) in the participants was 175 (IQR: 117, 250) µg/L, whereas the median salt consumption per person per day was 9.6 (IQR, 7.3-14.5) g. Sex, methods of salt storage, presence of goiter or thyroid nodules, the addition of salt in the cooking stage, and subclinical hypothyroidism had no effect on UIC, whereas individuals with hypertension and lower education had significantly lower iodine concentrations. UIC had a significant positive correlation with urine sodium and thyroid stimulating hormones (TSH) concentrations (P < 0.001, 0.046) and a negative correlation with thyroid volume and T4 (P = 0.029, 0.018). Conclusion: Iodine status in the adult population of Sadra city was categorized as sufficient, although the iodine concentrations reported in Tehran were insufficient. The contributing factor can be higher salt consumption or possible higher environmental iodine concentrations in Sadra city than Tehran.

Neuroprotective Effects of Rosa damascena Extract against Aluminum Chloride-Induced Brain Damage in Rat Offspring.

Aluminum (Al) is a popular metal in the industry, and its usage has greatly increased recently. The dose of this metal has been proven to be toxic to rats, but its effects on the offspring of the original receivers and prevention methods to reduce this damage are unknown. Rosa damascena is a well-known plant for its high antioxidant capabilities. In this study, the protective effect of Rosa damascena extract (RDA) on aluminum-induced lesions in the brain tissue of a rat offspring was investigated. In this regard, female rats were divided into seven groups, including the control group, the sham group, the aluminum group at the dose of 100 mg/kg, the extract groups at the doses of 500 and 1000 mg/kg, and the treatment groups that received the extract and Al at the same doses. After the treatment ended, the offsprings were subjected to exploratory behavioral tests, and finally, the tissues of the brain including the cerebral cortex, hippocampus, and hypothalamus were pathologically examined. It was observed that RDA at the dose of 1000 mg/kg reduced the malondialdehyde (MDA) and acetylcholinesterase (AChE) levels significantly (P < 0.0001), while raising the catalase and FRAP indices in Al-treated rats. Moreover, it increased neuronal counts significantly and reduced necrosis and vacuolar degeneration in both the cortex and hippocampus compared to the Al-receiving group. In addition, the administration of RDA 1000 improved the behavioral test scores of the offspring. In conclusion, RDA can effectively reduce Al-induced damage in the brain tissue of the offspring.
