RESUMEN

Objectives: Understanding the shape and size of the sella turcica may help predict future orthodontic treatment needs related to skeletal malocclusion. This study aims to assess different morphological types of the sella turcica in lateral cephalometric radiographs and its correlation with malocclusion, as well as the relationship between gender and linear measurements of sella turcica. Materials and Methods: The lateral cephalometric radiographs of 410 volunteers (111 men and 299 women) aged 8 to 30 years were evaluated. The patients were divided into three groups based on their skeletal growth patterns (cl I, II, and III). Then the anatomical shape and linear dimensions of sella turcica were assessed. Measurements were made using Adobe Photoshop Version: 20.0.0 software, and data analysis was performed by IBM SPSS Statistics version 25. Results: The following morphologies were observed: normal (37.8%), oblique anterior wall (9.3%), double contour of the floor (21.5%), sella turcica bridge (8.8%), irregularity (notching) in the posterior part of sella turcica (16.6%), and pyramidal shape of the dorsum sellae (6.1%). No statistically significant relationship was found between sella turcica variations and skeletal malocclusion. The correlation between female sex with the diameter (p=0.027) and depth values (p=0.035) of sella turcica was statistically significant. There was no statistically significant difference (p>0.05) in length based on gender. Conclusion: The most morphological type reported was normal sella turcica (37.8%). Anatomical variations of sella turcica had no association with malocclusion. The most considerable depth and diameter of sella turcica were found in women.

RESUMEN

This study aimed to assess the relationship between skeletal malocclusion and radiomorphometric indices of the mandible in long face patients. This cross-sectional study evaluated 174 lateral cephalograms and panoramic radiographs of long face patients between the ages of 17 and 30 presenting at the Orthodontics Department of Qazvin Dental School. The gonial angle, antegonial angle, type of antegonial notch, and depth of antegonial notch were measured bilaterally on panoramic radiographs. The correlation between the radiomorphometric parameters and the type of occlusion was analyzed using one-way ANOVA, independent t-test, Chi-square test, and Fisher's exact test (alpha = 0.05). The mean size of gonial angle was significantly different among the three classes of occlusion (p = 0.046), while the difference was not significant regarding the antegonial angle size and antegonial notch depth (p > 0.05). An independent t-test showed that the mean sizes of gonial angle (p = 0.026) and antegonial angle (p = 0.036), and the antegonial notch depth (p = 0.046) in males, were significantly greater than the values in females. According to the Chi-square and Fisher's exact test, the right antegonial notch type was significantly different among the three classes of malocclusion (p = 0.006), while this difference was not significant in the left side (p = 0.318). The right antegonial notch type II was more common in males, while the right antegonial notch type I was more common in females (p = 0.014). According to the results, the indices of gonial angle and type of antegonial notch can be clinically useful for predicting the growth rate of the mandible and designing the appropriate treatment in long face patients.

RESUMEN

This study aimed to assess the relationship of the morphology and size of the sella turcica (ST) with dental anomalies and skeletal malocclusions. This cross-sectional study was conducted on records of fixed orthodontic patients treated between 2013 and 2022. Cephalometric analysis was performed to determine the anteroposterior and vertical skeletal patterns. Preoperative panoramic radiographs and lateral cephalograms, intraoral photographs, and primary dental casts of patients were used to detect dental anomalies. Gender, sagittal and vertical skeletal patterns, dental anomalies, and dimensions (length, depth, and diameter), and morphology of the ST were all recorded according to the lateral cephalograms of patients. Data were analyzed using independent t-test, one-way and two-way ANOVA, Chi-square test, and log rank test (alpha = 0.05). The depth and diameter of the ST had no significant correlation with gender (p > 0.05); however, the length of the ST was significantly longer in males than females (p < 0.05). The morphology of the ST had a significant correlation with gender (p < 0.05). The ST morphology had a significant correlation with the anteroposterior skeletal pattern, microdontia, and tooth impaction as well (p < 0.05). The present results revealed a significant correlation of the ST morphology with the anteroposterior skeletal pattern, microdontia, and tooth impaction.

RESUMEN

Background: Polylactic-co-glycolic acid and zinc oxide (PLGA-ZnO) nanocomposite has been investigated for its antibacterial properties, which could be beneficial for adding to wound dressings after periodontal surgery. However, its cytotoxicity against human gingival fibroblasts (HGFs) remains unclear and should be evaluated. Methods: ZnO nanoparticles were synthesized using the hydrothermal method. These metallic nanoparticles were incorporated into the PLGA matrix by the solvent/non-solvent process. The nanomaterial was evaluated by field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and x-ray diffraction (XRD) analyses. HGF cells were acquired from the National Cell Bank and categorized into four groups: ZnO, PLGA, ZnO-PLGA, and control. The cells were exposed to different ZnO (1, 20, 40, 60, 80, and 100 µg/mL) and PLGA (0.2, 4, 8, 12, 16, and 20 µg/mL) concentrations for 24 and 48 hours. The cytotoxicity was tested using the MTT assay. The data were analyzed using SPSS 25, and P<0.05 was considered statistically significant. Results: ZnO nanoparticles exhibited significant toxicity at≥40 µg/mL concentrations after 24 hours. Cell viability decreased significantly at all the tested concentrations after 48 hours of exposure. PLGA-ZnO cell viability in 24 hours was similar to the control group for all the concentrations up to 80 µg/mL. Conclusion: ZnO nanoparticles could be toxic against HGF in high concentrations and with prolonged exposure. Therefore, incorporating ZnO nanoparticles into a biocompatible polymer such as PLGA could be a beneficial strategy for reducing their toxicity.

RESUMEN

BACKGROUND: Although the burden of anemia in pregnant women and its consequences on the pregnancy outcome are well documented, there is limited evidence on the association between maternal hemoglobin concentration and low birth weight (LBW) in the study area. OBJECTIVES: This study aimed to determine the association between maternal hemoglobin concentration and neonatal birth weight (BW) in Qazvin, Iran, 2018-2019. MATERIALS AND METHODS: A case-control study was conducted among 450 neonates with BW < 2500 gm (LBW) and 451 neonates with BW > 2500 gm. In this study, neonates with BW less than 2500 gm were cases, while those who were greater than 2500 gm were considered as control. Multiple logistic regression model was used to calculate OR with 95% Confidence Interval (95 % CI) to determine the association between maternal anemia and other maternal attributes and neonate BW. RESULTS: Maternal hemoglobin (g/dl) was not significantly associated with neonate BW (OR: 1.03 (95 % CI: 0.58 - 1.81), p = 0.93). However, maternal initial weight (Kg) (OR: 0.96 (95 % CI: 0.94 - .098), p < 0.001), mother's age in year (OR: 1.04 (95 % CI: 1.00 - 1.09), p = 0.038), gestational age (OR: 0.49 (95 % CI: 0.43 - 0.57), p < 0.001) were significantly associated with neonatal BW. CONCLUSION: Maternal hemoglobin concentration was not significantly associated with LBW. However, other maternal attributes such as low initial maternal weight, low gestational age, low education status and old age were significantly associated with LBW. Intervention that targeted mothers with low initial weight, low educational status and older age is required to minimize LBW among neonates in the study area.

RESUMEN

The pattern of expansion of endodontic lesions in the jaws has been less commonly addressed in the literature. For this reason, the aim of this study is to assess the pattern of endodontic lesions of maxillary and mandibular posterior teeth using cone-beam computed tomography (CBCT). This cross-sectional study was conducted on 317 endodontic lesions of posterior teeth on CBCT scans retrieved from a radiology center in Qazvin, Iran, from 2020 to 2022. Endodontic lesions were assessed on sagittal, coronal, and axial sections by an endodontist and dental student using the Romexis software. The largest lesion diameter was measured occluso-apically, mesiodistally, and buccolingually. Lesion size was analyzed based on age, gender, jaw, tooth type, and presence/absence of root filling by independent samples t-tests and a one-way Analysis Of Variannce (ANOVA). The largest diameter of lesions in the maxilla and mandible was recorded in the occluso-apical dimension followed by buccolingual and mesiodistal dimensions (p > 0.05). The pattern of lesions was the same in teeth with and without endodontic treatment, but it was significantly different in maxillary and mandibular endodontically treated teeth in the occluso-apical and buccolingual dimensions (p < 0.05). No significant correlation was noted with tooth type or jaw except for maxillary and mandibular first molar lesions, which were significantly different in the occluso-apical dimension (p < 0.05). Lesion size in all three dimensions was significantly greater in males than females (p < 0.05), and was the highest in the occluso-apical dimension in both genders. In the maxilla, the mean lesion size significantly decreased in the mesiodistal dimension with age (p < 0.05). In conclusion, the largest lesion diameter in the maxilla and mandible was found in the occluso-apical dimension, indicating the role of bone density in the pattern of lesions.

RESUMEN

Background: Hypocalcemia is highly prevalent in Coronavirus disease 2019 (COVID-19). There is limited evidence about the course and roles of different parameters in the occurrence of new or worsening hypocalcemia. Objectives: This prospective longitudinal study was conducted on hospitalized COVID-19 patients in Qazvin, Iran, in 2021. Methods: Serum levels of calcium, albumin, parathormone (PTH), 25(OH)D (vitamin D), magnesium, and phosphate were assessed on the first day (time one), as well as fourth to sixth days (time two) of hospitalization. Paired t-test, McNemar's test, and multivariate logistic regression test were used to compare data at two times and evaluating the independent roles of different variables in the occurrence or worsening of hypocalcemia. Results: Out of a total of 123 participants, 102 patients completed the study. The mean serum calcium level significantly decreased from 8.32 ± 0.52 mg/dL to 8.02 ± 0.55 mg/dL at time two compared to time one (P < 0.001). Also, we witnessed new or worsening hypocalcemia at time two in 44 (55%) patients with normal serum calcium or mild hypocalcemia at time one (P < 0.001). The PTH level decreased from 42.17 ± 27.20 pg/mL to 31.28 ± 23.42 pg/mL (P < 0.001). The decrease in albumin and PTH levels was an independent significant factor in the occurrence or worsening of hypocalcemia at time two (OR = 1.27; 95% CI: 1.10 - 1.46; P = 0.001 for each 1 g/L decrement in albumin and OR = 1.29; 95% CI: 1.03 - 1.62; P = 0.026 for each 10 pg/mL decrement in PTH). Vitamin D deficiency or changes during hospitalization did not have a significant role in new or worsening hypocalcemia. Conclusions: Decreased PTH secretion and hypoalbuminemia have significant roles in the occurrence of new or worsening hypocalcemia during hospitalization due to COVID-19.

RESUMEN

BACKGROUND: Unpleasant experiences of dysmenorrhea can lead to increased anxiety. The anxiety associated with dysmenorrhea is a pain-related anxiety which might reduce the efficacy of medication as well as enhance the perception of pain. The present study evaluated the efficacy of eye movement desensitization and reprocessing (EMDR) in reducing anxiety among female university students with primary dysmenorrhea. METHODS: In this randomized controlled trial, 88 female university students were recruited from April 2019 to February 2020. Eligible participants were selected by convenience sampling and were allocated into study groups (44 individuals in the intervention group and comparison group) using balanced block randomization. The final sample comprised 78 participants who completed the study (39 individuals in each group). Data were collected using the Spielberger State-Trait Anxiety Inventory, Subjective Units of Distress Scale, and Validity of Cognition Scale before the intervention and at the time of the first menstrual period after completion of the intervention. The intervention group received EMDR in two individual interventional sessions which lasted approximately one hour. Data analysis was performed using analysis of variance with control of covariance method at a significance level of 0.05. RESULTS: The results of the study showed that EMDR did not have a statistically significant effect on State-Trait Anxiety of patients with dysmenorrhea (p > 0.05). Based on the Cohen's d effect size of 0.06 for state-anxiety, -0.01 for trait-anxiety, and partial eta square less than 0.059 for both uncorrected and corrected models, the intervention was within a trivial effect. CONCLUSION: EMDR intervention did not have a statistically and clinically significant effect on State-Trait Anxiety of patients with dysmenorrhea. Therefore, the efficacy of EMDR in treating dysmenorrhea-related anxiety remains inconclusive. Trial registration IRCT20180823040851N2 on 2019-02-09.

RESUMEN

OBJECTIVE: The aim of the present study was to determine the relationship between temperature and air pollution, and preterm birth in Tehran, Iran. METHODS: In this time series study, the daily data of preterm births, air pollution, and maximum, minimum and mean temperature from March 2015 to March 2018 were used. To evaluate the effect of air pollution and temperature with and without adjustment of their mutual effects on preterm birth in lags (days) 0-21, the Distributed Lag Non-linear Models (DLNM) was used. The relative risk (RR) was estimated for extreme, moderate and mild heat (99th, 95th, 75th percentile) and cold (1st, 5th, 25th percentile) compared with the median, and for each 10-unit increase in PM2.5, NO2, and O3, 5-unit increase in SO2, and 1-unit increase in CO. RESULTS: The highest RR was seen in extreme (26.9 °C) and moderate (24.8 °C) heat of minimum temperature on lag 0 (RR = 1.17; 1.05-1.31, Adjusted RR = 1.16; 1.04-1.29, RR = 1.15; 1.05-1.26, Adjusted RR = 1.14; 1.03-1.25, respectively). In regard of cold, the only significant effect was for maximum temperature on lags 7-9 (RR = 1.02; 1.00-1.04). Each 10-unit increase in PM2.5 in Lag 0 (RR = 1.008; 1.001-1.014) and lag 1 (RR = 1.004; 1.001-1.007) and in NO2 in lag 0 (RR = 1.006; 1.000-1.012) had significant effects. CONCLUSION: Maternal exposure to a minimum daily temperature of 26.9 and 24.8 °C compared to 13.2 °C increased the risk of preterm birth by 17 and 15% on the same day, respectively. This risk increased by 0.8 and 0.6%, on the same day for each 10-unit increase in PM2.5 and NO2, respectively.

RESUMEN

A cross-sectional study with a convenience sample of 241 patients with breast cancer was conducted to investigate death depression and its explanatory factors in Iranian women who were diagnosed and undergoing treatment for breast cancer. Patients with significantly higher death depression were those who were housewives (ß = 0.6, p = 0.016), unskilled workers (ß = 15.8, p = 0.002), and retired (ß = 13.1, p = 0.002) as compared with those who were professionally employed with higher socio-economic status (ß = 17.4, p = 0.002); and those receiving combination therapy as compared to surgery only (ß = 6.3, p = 0.02). For patients with higher spiritual health scores, death depression was significantly lower (ß = -0.2, p < 0.001).

RESUMEN

Since the beginning of the COVID-19 pandemic, many Iranian people have been taking 50 000 IU of vitamin D3 on weekly or biweekly bases in order to enhance their immune system function. This cross-sectional study was conducted on the patients of endocrinology clinic to compare 25(OH)D levels of weekly or biweekly consumption with the monthly users of vitamin D3 50 000 IU. The level >100 ng/mL of 25(OH)D was defined as hypervitaminosis D. In total, 211 patients (108 and 103 patients in monthly and weekly/biweekly groups, respectively) were studied. In the subgroups of weekly and biweekly users, the rates of hypervitaminosis were 18.9% and 4.5%, respectively. In contrast, only 0.9% of monthly users had hypervitaminosis D. The highest vitamin D value of 185 ng/mL was detected in a patient who had consumed 50 000 IU vitamin D3 weekly for 6 years. No hypercalcaemia was detected in patients with hypervitaminosis D.

RESUMEN

OBJECTIVES: This systematic review and meta-analysis study aimed to estimate the overall prevalence of Glucose-6-phosphate dehydrogenase (G6PD) deficiency in neonates with jaundice who were admitted to hospitals in Iran. MATERIALS AND METHODS: In this systematic review and meta-analysis, we searched PubMed/Medline, Scopus, ISI Web of Sciences, and Iranian Local databases up to December 2019.We calculated Prevalence and 95% Confidence Interval (95% CI) of G6PD deficiency as summary measures. We conducted subgroup analysis based on the sex and quality of studies, while meta-regression were applied for investigating the effect of years of studies and years of publication on the pooled prevalence. We applied sensitivity analysis to investigate the effect of excluding each study on the pooled prevalence estimation. RESULTS: The total sample size was 9799 people. The pooled prevalence of G6PD deficiency among neonates with jaundice in Iran was 7.0% (95% CI: 5.5-8.5%). The results of subgroup analysis showed that, pooled prevalence of G6PD deficiency among male neonate (12.1%, 95%CI: 7.6-16.7%) was more prevalent that female (3.00%, 95%CI: 1.1-4.9%). Based on the sensitivity analysis, lower and higher pooled prevalence of G6PD deficiency was observed 5.8% (95%CI: 4.7-6.9%) and 7.3% (95%CI: 5.7-8.8%) respectively by excluding each study. CONCLUSION: The overall prevalence of G6PD deficiency was 7% in Iranian neonates with Jaundice. Prevalence was high in male and early hours of life. We recommend screening test for G6PD deficiency in neonates to prevent its complications.

RESUMEN

The global issue of preventing the spread of COVID-19 is challenging. One of the most efficient ways to control the pandemic is to have a full coverage of COVID-19 vaccination. Therefore, this paper collected survey data to understand the intention and willingness of COVID-19 vaccination uptake in Qazvin, Iran. With the use of a paper-and-pencil method and multistage stratified cluster sampling, research personnel approached and interviewed a representative sample of adults in Qazvin (n = 10843) between February 19 and April 9, 2021. The survey asked questions regarding sociodemographic information, fear of COVID-19, perceived COVID-19 infectability, perceived behavioral control over COVID-19 vaccination, subjective norm of COVID-19 vaccination, attitude towards COVID-19 vaccination, and intention to get COVID-19 vaccinated. The data collected from this survey were analyzed using descriptive statistics, which were carried out using the IBM SPSS version 17.0.

RESUMEN

One of the most efficient methods to control the high infection rate of the coronavirus disease 2019 (COVID-19) is to have a high coverage of COVID-19 vaccination worldwide. Therefore, it is important to understand individuals' intention to get COVID-19 vaccinated. The present study applied the Theory of Planned Behavior (TPB) to explain the intention to get COVID-19 vaccinated among a representative sample in Qazvin, Iran. The TPB uses psychological constructs of attitude, subjective norm, and perceived behavioral control to explain an individual's intention to perform a behavior. Fear and perceived infectability were additionally incorporated into the TPB to explain the intention to get COVID-19 vaccinated. Utilizing multistage stratified cluster sampling, 10,843 participants (4092 males; 37.7%) with a mean age of 35.54 years (SD = 12.00) completed a survey. The survey assessed TPB constructs (including attitude, subjective norm, perceived behavioral control, and intention related to COVID-19 vaccination) together with fear of COVID-19 and perceived COVID-19 infectability. Structural equation modeling (SEM) was performed to examine whether fear of COVID-19, perceived infectability, and the TPB constructs explained individuals' intention to get COVID-19 vaccinated. The SEM demonstrated satisfactory fit (comparative fit index = 0.970; Tucker-Lewis index = 0.962; root mean square error of approximation = 0.040; standardized root mean square residual = 0.050). Moreover, perceived behavioral control, subjective norm, attitude, and perceived COVID-19 infectability significantly explained individuals' intention to get COVID-19 vaccinated. Perceived COVID-19 infectability and TPB constructs were all significant mediators in the relationship between fear of COVID-19 and intention to get COVID-19 vaccinated. Incorporating fear of COVID-19 and perceived COVID-19 infectability effectively into the TPB explained Iranians' intention to get COVID-19 vaccinated. Therefore, Iranians who have a strong belief in Muslim religion may improve their intention to get COVID-19 vaccinated via these constructs.

RESUMEN

OBJECTIVES: This study aimed to determine the effect of ambient air pollution and temperature on stillbirth in Tehran. METHODS: In this time-series study, the effect of O3 (ppb), CO (ppm), NO2 (ppb), SO2 (ppb), PM2.5 (µg/m3), and minimum, maximum, and mean daily temperature (°C) on stillbirth was evaluated in Tehran, Iran between March 2015 and March 2018. Using a quasi-Poisson regression model in combination with a Distributed Lag Non-linear Models (DLNM), the Relative Risk (RR) was estimated through comparing the high temperature (99th, 95th, and 75th percentiles) and low temperature (1st, 5th, and 25th percentiles) with the median. The effect of air pollution was estimated for each 1-, 5-, or 10-unit increase in the concentration during lags (days) 0-21. RESULTS: Among air pollutants, only a 5-ppm increase in the SO2 concentration in lag 0 increased the risk of stillbirth significantly (RR = 1.062; 1.002-1.125). The largest effect of heat was observed while comparing the 99th percentile of minimum daily temperature (26.9 °C) with the median temperature (13.2 °C), which was not statistically significant (RR = 1.25; 0.95-1.65). As for cold, a non-significant protective effect was observed while comparing the 1st percentile of maximum daily temperature (3.1 °C) with the median temperature (23.2 °C) (RR = 0.92; 0.72-1.19). CONCLUSION: Each 5-ppm increase in the mean daily SO2 in lag 0 increased the risk of stillbirth by 6% while other air pollutants had no significant effects on stillbirth. In lags 0 and 1, the heat increased the risk of stillbirth while the cold had protective effects, which were not statistically significant.

RESUMEN

The aim of the present study was to investigate the effect of silymarin (Livergol) on liver enzymes in patients taking isotretinoin (Roaccutane). In this double-blind clinical trial, 74 patients with acne and taking isotretinoin were randomly assigned into intervention (N = 37) and control (N = 37) groups. The intervention group received a 140 mg Livergol capsule per day for 30 days. The control group received a starch-containing capsule as a placebo once a day for 30 days. Liver enzyme levels were measured before and after the intervention. The data were analyzed using chi-square test, Independent t test, paired sample t test and analysis of covariance (ANCOVA). The results showed no statistically significant difference between the intervention and control groups at the beginning of study in levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) (p > .05). At the end of the study, a statistically significant difference was observed between the two groups in levels of AST and ALT (p < .05). Livergol prevented liver enzymes from increasing, so it can be used as an effective, low-cost, and low-complication treatment for the problem of increased levels of liver enzymes following the use of isotretinoin.

RESUMEN

BACKGROUND: Mobile phone dependency is an emerging public health problem. The aim of this study was to investigate the associations between general health and mobile phone dependency in college students. METHODS: In this cross-sectional study, 334 students from Arak University of Medical Sciences of Iran were selected by stratified random sampling. Data were collected by (1) demographic checklist, (2) 27-item Mobile Phone Problem Usage Scale, and (3) General Health Questionnaire-28 (GHQ-28). RESULTS: Mean scores of mobile phone dependency and GHQ-28 were 119.83 ± 43.53 and 23.73 ± 12.77, respectively. In multiple linear regression, age, family economic status, anxiety and sleep disorder, and social dysfunction were the main significant predictors of mobile phone dependency (R = 0.469, R 2 = 0.220, adjusted R 2 = 0.203). CONCLUSIONS: Based on the finding of this study, prevention strategies for management of mobile phone use in students can be adopted.

RESUMEN

BACKGROUND: Unpleasant experience with the previous menstruation can increase the sensitivity to pain which may lead to moderate to severe pain in patients with dysmenorrhea. Eye movement desensitization and reprocessing (EMDR) is a psychological method to alleviate the distress from unpleasant memories and related events and can be used for other conditions such as anxiety, depression, and chronic pain. This protocol was designed to investigate the effect of EMDR therapy on pain intensity in patients with dysmenorrhea. METHODS/DESIGN: A randomized clinical trial was designed in compliance with the Consolidated Standards of Reporting Trials (CONSORT). Female students who have moderate to severe primary dysmenorrhea (based on a visual analogue scale [VAS] score of at least 4 for two consecutive months) and who live in dormitories at Qazvin University of Medical Sciences in Qazvin, Iran will be invited to participate in the study. The total sample size will be 88 girls, who will be randomly assigned to intervention (N = 44) and control (N = 44) groups. EMDR therapy will be performed for the intervention group, while the control group can use sedative or other pain relife methods as their routin... There will be six treatment sessions, which will be held twice a week. The duration of each session is 30-90 min, according to the convenience of each participant. The data will be collected using the demographic characteristics questionnaire, the VAS, the Subjective Units of Anxiety or Distress Scale (SUD), and the Validity of Cognition Scale (VOC). The data on pain intensity due to primary dysmenorrhea in both groups will be collected at 1 and 2 months before the intervention (to identify eligible participants) and 1 and 2 months after the intervention (follow-ups). Data will be analyzed by using SPSS version 25 software and analysis of variance (ANOVA) with repeated measures with appropriate post hoc tests. A P value of less than 0.05 will be considered significant. DISCUSSION: The results are expected to provide the information on the efficacy of EMDR therapy to manage moderate to severe pain in patients with primary dysmenorrhea. ETHICS AND DISSEMINATION: The research proposal is approved by the human ethics committee of Qazvin University of Medical Sciences (IR.QUMS.REC.1397.100). The results of this trial will be submitted for publication in a peer-reviewed research journal. TRIAL REGISTRATION: IRCT20180823040851N1 . Registered on 6, October 2018.

RESUMEN

AIMS: This study aims to determine the association between depression with glycemic control (HbA1c) and its complications. MATERIALS AND METHODS: This was a cross-sectional study that included 514 diabetic patients. The patients were randomly selected from among all type 2 diabetes patients referred to health and medical centers in Khorramabad town (Iran). Two questionnaires used for data collection. The first questionnaire included demographic information, diabetes and its complications and the second questionnaire was Beck Depression Inventory (BDI-II) which was used to assess depression. The stata software version 14 was used for data analysis. Then, for evaluate the association between depression with glycemic contol and its complications, Univariate and multiple logistic regression analysis were employed. RESULTS: The prevalence of depression in diabetic patients under study was 46.3% and for female and male was 49.6 and 36.8%; respectively. The results showed that 48.6% of diabetic patients did not have appropriate glycemic control status (HbA1c > 8). There was no significant association between glycemic control expressed as HbA1c levels and depression (OR: 1.11, 95% CI: 0.87-1.57). By contrast, sex (OR: 2.03, CI 95%: 1.03-3.99), residence (OR: 1.92, 95% CI: 1.28-2.91) and sexual complications (OR: 5.54, 95% CI: 1.07-27.87) have a significant statistical association with depression. CONCLUSION: The study highlights the high prevalence of depression in diabetic patients. However, there was no significant association between depression and glycemic control. The implementation of mental health screening for rapid diagnosis and timely treatment of depression seems essential in diabetic patients.

RESUMEN

PURPOSE: The present study aimed to determine the prevalence of childhood obesity and overweight in Iranian children under 5 years of age using a systematic review and meta-analysis. METHODS: We searched MEDLINE (PubMed), Web of Science, Google Scholar, Scopus, CINHAL, and the Iranian databases, including Scientific Information Database (www.sid.ir), Iranian Research Institute for Information Science and Technology (Irandoc.ac.ir), Iranmedex (www.iranmedex.com), and Magiran (www.magiran.com), for all articles published between January 1989 and August 2017. Sources of heterogeneity were determined using subgroup analysis and meta-regression. RESULTS: Six articles were ultimately included in the meta-analysis to estimate the pooled prevalence, based on which the prevalence of obesity and overweight were estimated to be 8% (95% confidence interval [CI], 6%-10%) and 9% (95% CI, 7%-11%), respectively. The results of the subgroup analysis showed that the prevalence of obesity in boys and girls was 9% (95% CI, 6%-13%) and 7% (95% CI, 4-10%), respectively, and the prevalence of overweight in boys and girls was 10% (95% CI, 5%-15%) and 9% (95% CI, 5%-13%), respectively. CONCLUSION: Despite high heterogeneity among the results of the articles included in the meta-analysis, the prevalence of obesity and overweight is higher in Iranian children under 5 years of age. Therefore, parents and the health system must pay more attention to the lifestyle, nutritional habits, and physical activity of these children.
