RESUMEN
BACKGROUND: Health literacy and e-health literacy are important factors helping people shape awareness of health behaviours in different aspects, including sleep hygiene behaviours. Good sleep hygiene behaviours promote sleep quality and are beneficial to overall mental wellbeing. OBJECTIVE: We aimed to examine if sleep hygiene behaviours may mediate the association between health literacy/e-health literacy and mental wellbeing. METHODS: Adult Iranian subjects (n = 9775; mean [SD] age = 36.44 [11.97] years; 67.3% females) completed the Health Literacy Instrument for Adults, eHealth Literacy Scale, three items on sleep hygiene behaviour that have been used in prior research and the Short Warwick Edinburgh Mental Wellbeing Scale. Data were then subjected to structural equation modelling (SEM) including 500 bootstrapping resampling to examine whether sleep hygiene is a mediator in the relationship between health literacy/e-health literacy and mental wellbeing. FINDINGS: Both health literacy and e-health literacy were significantly associated with mental wellbeing (r = .63 for health literacy and .39 for e-health literacy; p < .001) and sleep hygiene behaviours (r = .58 for health literacy and .36 for e-health literacy; p < .001). Sleep hygiene behaviours were significantly associated with mental wellbeing (r = .42; p < .001). Moreover, SEM that incorporated bootstrapping approaches indicated that sleep hygiene behaviours were significant mediators in the association between health literacy/e-health literacy and mental wellbeing. CONCLUSIONS: We conclude that health literacy and e-health literacy are associated with mental health wellbeing in the Iranian population. Additionally, the association could be mediated via sleep hygiene behaviours. PATIENT OR PUBLIC CONTRIBUTION: The study was co-designed with healthcare providers from the vice-Chancellor's Office for Health Affairs of Qazvin University of Medical Sciences as equal partners. Moreover, the women's health volunteers were involved in the design of the study.

BACKGROUND: Prenatal corticosteroid administration in preterm labor is one of the most important treatments available to improve neonatal outcomes; however, its beneficial effects on late preterm infants (after the 34th week of gestation) remained unknown. We aimed to assess the effects of betamethasone on the clinical condition of the late preterm infants born between 34 and 36 weeks of gestation. METHODS: This retrospective cohort study was performed on 100 consecutive infants born between 34 and 36 weeks of gestation and received betamethasone before delivery as the cases and 100 neonates with the same delivery conditions but without receiving betamethasone. All neonates were followed up within hospitalization to assess the neonatal outcome. RESULTS: The neonates receiving betamethasone suffered more from respiratory distress syndrome (49% versus 31%, p = 0.008, RR = 1.59 95% CI (1.12-2.27)) and requiring more respiratory support (71% versus 50%, p = 0.002, RR = 1.43 95% CI (1.13-1.80)) as compared to the control group. There was no difference between the two groups in other neonatal adverse events or death. CONCLUSION: the use of betamethasone in the late preterm period (after 34 weeks of gestation) has no beneficial effects on lung maturity or preventing neonatal adverse outcomes, even may lead to increase the risk for RDS and requiring respiratory support.

AIM: We aim to evaluate the reproductive outcome of fertility-sparing surgery and chemotherapy among young women diagnosed with MOGCT of any stage. METHODS: In the current retrospective study we evaluated 79 patients with malignant ovarian germ cell tumors (MOGCT) who visited at Imam Center, Vali-e-asr Hospital, Gynecologic Oncology department during 2001-2016. Reproductive outcomes (menstruation status and childbearing) followed fertility-preserving surgery and adjuvant chemotherapy by filling questionnaires. Statistical analysis was done with SPSS software, Chi-Square Tests were done, and significance was determined at P ≤ 0.05. Results among 79 young women who underwent fertility-sparing treatment, 72 patients followed up for reproductive outcome, and 7 patients excluded because of death (3 cases), XY genotyping (3 cases), and bilateral ovarian involvement (1 case). The mean age at presentation was 23 years. (Range: 19-33 years). The 5 and 10-year disease-free survival rate was 87% and 94.4%, respectively. The overall survival rate (OSR) was 94.4% at 5 and 10 years. Regular menstruation recovered in 60 of 72 patients after treatment (83%). All patients without adjuvant chemotherapy experienced regular menstruation, while normal menstruation was retrieved in 78% in the adjuvant chemotherapy group at the end of treatment. This retrieval of regular menstruation was not dependent on the age or number of chemotherapy cycles. 19 of 26 patients who attempted pregnancy were led to delivery (73%). No one required infertility treatments. The mean of chemotherapy cycles is related to a successful pregnancy. CONCLUSION: We showed patients with MOGCT could become pregnant and give birth if they desire. The advanced tumor stage wasn't the convincing factor for avoiding fertility preservation. Fertility sparing surgery with adjuvant chemotherapy is a safe treatment and results in a high fertility rate.

The alumina nanoparticles (NPs) have been synthesized from reaction between alum with ammonia and then calcined the precipitate at 1200 °C for 4 h. Its surface was modified by oleic acid (OA) and trimethoxyvinylsilane (TMVS) in o-xylene at 50 °C. The alumina NPs and its modified were characterized by XRD, FT-IR, SEM, EDX and TGA. The TGA analysis indicated that the grafting amount of OA and TMVS were 10.5 and 8.0% respectively. The dispersion of modified NPs was determined in monomers such as methyl methacrylate (MMA), butyl acrylate (BuA) and styrene (St) and in solvents such as ethanol, hexane and acetone. The experimental results showed that the highest dispersion was happened NPs modified by oleic acid in n-hexane, while the highest dispersion was observed NPs modified by TMVS in acetone. The results indicate that NPs modified by oleic acid formed a stable dispersion in MMA and BuA. The highest amount of dispersion happened NPs modified by oleic acid in MMA and BuA in initial weight of 5 and 2.5% respectively, while stable dispersion is formed in styrene when TMVS is used as modifier. The highest amount of dispersion was happened NPs modified by TMVS in styrene in initial weight of 2.5%.
RESUMEN
Complex environmental conditions like heavy metal contamination and elevated CO2 concentration may cause numerous plant stresses and lead to considerable crop losses worldwide. Cadmium is a non-essential element and potentially highly toxic soil metal pollution, causing oxidative stress in plants and human toxicity. In order to assess a combination of complex factors on the responses of two genotypes of Festuca arundinacea (75B and 75C), a greenhouse experiment was conducted on plants grown in two Cd-contaminated soil conditions and two soil textures under combined effects of elevated ambient CO2 (700 ppm) and Epichloë endophyte infection. Plant biomass, Cd, Fe, Cu, Zn, and Mn concentrations in the plant shoots and roots, Fv/Fm, chlorophyll (a & b), and carotenoid contents were measured after 7 months of growth in pots. Our results showed that endophyte-infected plants (E+) grown in elevated CO2 atmosphere (CO2+), clay-loam soil texture (H) with no Cd amendment (Cd-) in the genotype 75B had significantly greater shoot and root biomass than non-infected plants (E-) grown in ambient CO2 concentration (CO2-), sandy-loam soil texture (L) with amended Cd (Cd+) in the genotype 75C. Increased CO2 concentration and endophyte infection, especially in the genotype 75B, enabled Festuca for greater phytoremediation of Cd because of higher tolerance to Cd stress and higher biomass accumulation in the plant genotype. However, CO2 enrichment negatively influenced the plant mineral absorption due to the inhibitory effects of high Cd concentration in shoots and roots. It is concluded that Cd phytoremediation can be positively affected by the increased atmospheric CO2 concentration, tolerant plant genotype, heavy soil texture, and Epichloë endophyte. Using Taguchi and AIC design methodologies, it was also predicted that the most critical factors affecting Cd phytoremediation potential were CO2 concentration and plant genotype.

INTRODUCTION AND IMPORTANCE: Uterine rupture is a rare condition that typically occurs in a scarred uterus and can happen during late pregnancy, labor, or the early postpartum period. Since most cases are seen in patients with a history of cesarean surgery, the anterior lower uterine segment is the most affected area. Most patients present with acute symptoms that compromise the fetus and the mother in a life-threatening manner. CASE PRESENTATION: We present a case of uterine rupture with subacute symptoms occurring in the second trimester, which is extremely rare. The patient was a stable second-trimester multiparous woman with chronic abdominal pain, but without any signs of peritoneal bleeding or instability. No history of previous cesarean section was present, and she had recently undergone a non-complicated hysteroscopic polypectomy. Transabdominal and transvaginal ultrasounds were performed, revealing a significant full-thickness myometrial defect in the posterior uterine lower segment. This defect allowed the amniotic sac to protrude into the posterior cul-de-sac. No abdominopelvic hematoma was detected. These findings were confirmed in an urgent MRI, and the patient underwent a laparotomy during which a significant full-thickness defect was discovered at the posterior of the uterus. As it was impossible to continue the pregnancy, the fetus was surgically removed and then prepared using multiple layers. CLINICAL DISCUSSION: The difference between our case and the previously reported one is in the aspect of gradual stable presentation and lacks of vaginal bleeding. CONCLUSION: Previous hysteroscopy carries a risk for future pregnancy complications, such as uterine rupture.
RESUMEN
INTRODUCTION: Bilateral tubal ectopic pregnancy (BTP) is a rare and potentially life-threatening condition that is, often challenging to diagnose preoperatively. PRESENTATION OF CASE: We present a case of BTP in a 25-year-old primigravid woman with a history of infertility due to polycystic ovarian syndrome. She was receiving letrozole when she presented with severe abdominal pain and vaginal bleeding. Initial evaluation revealed a ruptured ectopic pregnancy in the right fallopian tube, prompting an emergency laparotomy. During surgery, a second intact ectopic mass was discovered in the left fallopian tube, highlighting the diagnostic complexity of BTP. Management involved a salpingectomy on the right side and salpingostomy on the left to preserve fertility. DISCUSSION: This case underscores the importance of considering BTP in the differential diagnosis of ectopic pregnancies and the necessity for thorough preoperative imaging studies, namely ultrasonography and surgical exploration, to prevent missed diagnoses. CONCLUSION: BTP is a rare and challenging clinical entity that requires a comprehensive approach to diagnosis and management. Early recognition, prompt intervention, and close surveillance are essential to mitigate the risk of maternal morbidity and mortality associated with this condition.
RESUMEN
PURPOSE: Concurrent chemoradiation has been the mainstay of treatment for cervix cancer. We aimed to evaluate the non-inferiority of hypofractionated chemoradiation. METHODS: This study was designed as a phase 2, 1:1 randomized, investigator-blinded, controlled, non-inferiority trial and we report the interim results after 50% accrual. Cervical cancer patients with FIGO stages IIA-IIIC were recruited from April 2021 to September 2022. The intervention consisted of 40 Gy of 3D-conformal radiation therapy (RT) in 15 fractions over 3 weeks. In the control group, patients received standard chemoradiation of 45 Gy in 25 fractions over 5 weeks. Both groups received concurrent weekly cisplatin (40 mg/m2). Intravaginal brachytherapy of 28 Gy in 4 weekly fractions was delivered starting 1 week after the end of chemoradiation. The primary outcome was complete clinical response(CCR) at 3 months. Secondary outcomes included acute gastrointestinal (GI), genitourinary(GU), skin, and hematologic toxicities. A p value less than 0.05 was considered significant for analyses. RESULTS: 59 patients were randomized; 30 in the control group and 29 in the intervention group. 20/30 (66.7%) of the patients in the control group and 19/29 (65.5%) in the intervention group achieved a CCR (absolute difference of 0.011, 95% CI - 0.23 to 0.25, p value: 0.13). There was a significantly higher rate of acute grade ≥ 3 GI toxicity in the intervention group (27.6%) compared with the control group (6.7%) (p value 0.032). CONCLUSIONS: Despite an absolute difference of 1.1% in the 3-month CCR, our interim analysis failed to show the non-inferiority of the hypofractionated chemoradiation. Due to the higher GI toxicities, we will continue this trial using intensity-modulated radiation therapy. REGISTRATION NUMBER AND DATE: ClinicalTrials.gov: NCT04831437, 2021.4.1.

General and electronic health literacy are important factors engaging in healthy behaviors and maintaining good health. The present study explored demographic factors associated with general and electronic health literacy in the Iranian adult population. Via stratified cluster sampling, trained interviewers visited adult residents in Qazvin Province, Iran between January, and April 2022. The participants (N = 9775; mean age = 36.44 years; 6576 [67.3%] females) completed the Health Literacy Instrument for Adults (HELIA) assessing health literacy and the eHealth Literacy Scale (eHEALS) assessing electronic health literacy. Demographic data, including age, gender, educational level, marital status, and living location (city or rural), were collected. Latent class analysis (LCA) was used to classify the participants into different health literacy/electronic health literacy levels. The relationships between health literacy/electronic health literacy levels and demographic factors were examined using χ2 or analysis of variance. The LCA used HELIA scores to suggest five classes of health literacy and eHEALS scores to suggest three classes of electronic health literacy. For general and electronic health literacy, similar relationships were with demographic factors: females as compared with males had better general/electronic health literacy; younger people as compared with older people had better general/electronic health literacy; higher educational level was associated with better general/electronic health literacy; and city residents as compared with rural residents had better general/electronic health literacy. In conclusion, Iranian governmental agencies may wish to target on males, older adults, people with low educational level, and rural residents to improve their health literacy.

Retroperitoneal sarcoma is relatively uncommon. We share our experience in encountering retroperitoneal sarcoma with vascular and urethral adhesion in a 46-year-old woman. Given the rarity of these tumors, evaluation and management should ideally be performed in a center equipped with multidisciplinary expertise in treating sarcomas.
RESUMEN
BACKGROUND: Synchronous endometrial and ovarian cancer (SEOC) is a relatively rare entity with indistinct clinical manifestation but have a better prognosis compared to metastatic malignancy of each organ. The aim of the study is to determine the prognosis and factors associated with recurrence of SEOC. METHODS: This case-series study was performed on 37 histologically confirmed SEOC, diagnosed and treated in our tertiary hospital from March 2009 to September 2021. Disease-free survival (DFS) and overall survival (OS) rates following indicated procedure were calculated using the Kaplan-Meier method. Univariate and multivariate Cox regression analysis were used to determine risk factors of recurrence. RESULTS: The mean age of participants was 49.38 (age range: 26-78). The most common complaints and symptoms were abdominal pain (40.5%), followed by abnormal uterine bleeding (29.7%). Most common histological presentation was endometroid type for both ovarian (46%) and endometrial (97.3%) cancers. Over the mean follow-up period of 85.54 months, 11 patients developed recurrence without mortality. Non-endometrioid histology of ovarian cancer, higher grade and stage of ovarian cancer, and omentum invasion were significantly associated with worse DFS in unvariate analysis. Lymphovascular invasion was the sole predictor of DFS in multivariate analysis. CONCLUSION: While this study was not able to investigate the risk factors of overall survival associated with SEOC, the results of this study provides an overview of clinicopathological presentation of the disease and emphasizes the importance of lymphovascular invasion in determining prognosis and DFS in SEOC.

Background: Methotrexate (MTX) and actinomycin D (ActD) have been used as first-line chemotherapy agents in the treatment of low-risk gestational trophoblastic neoplasia (GTN). Although low-risk GTN is considered a curable disease, its reported primary remission rates of 49 to 93% reflect the difficulties of treatment and different factors influencing it. Hence, this study aimed to determine the remission rates and related factors of single-agent chemotherapy resistance in low-risk GTN patients. Methods: This retrospective study included patients with diagnosed low-risk GTN who received either MTX once a week (IM, 30mg/m2) or ActD once every two weeks (pulsed IV, 1.25mg/m2). Then, the patients were followed-up until complete remission or single-agent treatment failure to assess resistance rate and related factors. Results: Eighty-four patients were included in the study (18 patients were receiving MTX and 66 patients were receiving ActD). 85.7% of all participants achieved complete remission after first-line chemotherapy (72.2% in MTX vs 89.4% in ActD). There was a significant association for higher tumor size (P=0.046), the occurrence of metastasis (P=0.019), and pretreatment ß-HCG levels (P=0.005) with resistance to treatment. Conclusion: This study demonstrated higher tumor size, the occurrence of metastasis, and pretreatment ß-HCG levels have been associated with increased resistance to first-line chemotherapy agents.
RESUMEN
INTRODUCTION AND IMPORTANCE: Mullerian adenosarcoma is a rare malignancy that generally occurs in the uterine corpus but uncommonly, it may be found extrauterine. Ovarian adenosarcoma is extremely rare and often is presented in reproductive age women. Most of them are low grade and have à good prognosis except for adenosarcoma with sarcomatous overgrowth. CASE PRESENTATION: A 77-year-old menopausal woman presented with abdominal discomfort. She had severe ascites and elevated levels of CA-125, CA 19-9, and HE4 tumor markers. Adenosarcoma with sarcomatous overgrowth was diagnosed after the histopathological examination of the surgical biopsy. CONCLUSION: The possibility of endometriosis transformation to malignancy even in postmenopausal women may warrant continuous follow-up for early diagnosis of ovarian cancer, this potentially fatal disease. More studies are needed to find the best therapeutic approach to adenosarcoma with sarcomatous overgrowth.
RESUMEN
BACKGROUND: Based on recent advances in tissue engineering and stem cell therapy in nervous system diseases treatments, this study aimed to investigate sciatic nerve regeneration using human endometrial stem cells (hEnSCs) encapsulated fibrin gel containing chitosan nanoparticle loaded by insulin (Ins-CPs). Stem cells and also Insulin (Ins), which is a strong signaling molecule in peripheral nerve regeneration, play an important role in neural tissue engineering. METHODS: The fibrin hydrogel scaffold containing insulin loaded chitosan particles was synthesized and characterized. Release profiles of insulin from hydrogel was determined through UV-visible spectroscopy. Also, human endometrial stem cells encapsulated in hydrogel and its cell biocompatibility were assigned. Furthermore, the sciatic nerve crush injury was carried out and prepared fibrin gel was injected at the crush injury site by an 18-gage needle. Eight and twelve weeks later, the recovery of motor and sensory function and histopathological evaluation were assessed. RESULTS: The in vitro experiments showed that the insulin can promote hEnSCs proliferation within a certain concentration range. Animals' treatment confirmed that developed fibrin gel containing Ins-CPs and hEnSCs significantly improves motor function and sensory recovery. Hematoxylin and Eosin (H&E) images provided from cross-sectional and, longitudinal-sections of the harvested regenerative nerve showed that regenerative nerve fibers had been formed and accompanied with new blood vessels in the fibrin/insulin/hEnSCs group. CONCLUSION: Our results demonstrated that the prepared hydrogel scaffolds containing insulin nanoparticles and hEnSCs could be considered as a potential biomaterial aimed at regeneration of sciatic nerves.
RESUMEN
The collected data included socio-demographic information and measurements of health literacy, e-health literacy, mental well-being, and sleep hygiene behaviors. The study aimed to provide insights regarding health literacy status and related factors in the general population residing in Qazvin province, Iran. The findings of the study will assist health authorities and policy makers in developing and implementing effective interventions, which in turn, improving health literacy in the community. Additionally, the findings can also aid health sector workers, including non-communicable disease researchers, public health experts, health education specialists, epidemiologists, and sociologists, in their work to improve health literacy and overall health outcomes among general population. Therefore, the present study used paper-pencil method with multi-stage cluster sampling to collect data. Trained research associates (n=25) collected data from 9775 people living in Qazvin province between January and April 2022. All the participants completed the study questionnaires using self-reported paper-pencil mode.
RESUMEN
BACKGROUND: The placental examination provides important information about the effect of maternal abnormalities on the placenta or the cause of preterm delivery, fetal growth restriction, or fetal neurodevelopmental damage. In this study, the frequency of placental pathologies of patients in a tertiary hospital was investigated. METHODS: In this longitudinal and cross-sectional study, all removed placentas after any type of pregnancy termination referred to a pathological examination, within 1 year (2019-2020). All placentas were examined macroscopically and microscopically by two pathologists. RESULTS: Unfortunately, because of the COVID-19 pandemic, the number of pregnant women in our hospital declined. A total of 258 placentas were examined. The type of delivery in 193 cases (79.4%) was cesarean section and 50 cases (20.6%) had a vaginal delivery. In the pathological assessment of placentas, 238 (92.2%) cases were normal and 20 cases (7.8%) were abnormal. Infarct and chorioamnionitis were the pathologies with higher frequencies (4.3% and 2.7%, respectively). Intra-uterine fetal death (p = 0.701), preeclampsia (p = 0.51) had no significant difference was seen in normal and abnormal placentas. Maternal age (p = 0.83), gestational age based on the last menstrual period (p = 0.38), and gestational age based on the first ultrasound (p = 0.78) did not show a significant relationship with any of the pathological complications categories. CONCLUSIONS: Pathological examination of the placenta from all live-birth deliveries is not worthwhile, and it's recommended to modify the guidelines as to when the placenta is submitted for pathological evaluation.

Introduction: There was an increase in number of patients presented with early-stage cervical cancer (CC). Tumors with favorable pathological features might be candidates for less radical surgery. Methods: We retrospectively reviewed 700 patients with histologically confirmed CC between January 2011 and March 2020. Chi-square, Fisher's exact tests and multivariate logistic regression analysis were used to assess relations between parametrial involvement (PI) and clinic-pathological variables. Results: Total number of 132 patients with stage IA to IIA were eligible to participate. Squamous cell carcinoma was reported in 100 (75.8%) patients, adenocarcinoma and other tumor pathologies were found in 24(18.2%) and 8(6.1%), respectively. Considering the 2018 FIGO stage, 11 (8.4%) patients had IA, 111 (83%%) IB and 10 (7.6%) IIA. Nine patients (6.8%) had PI on permanent pathologic report. Univariate analysis demonstrated that following variables were statistically different between patients with and without PI: age ≥50, tumor size ≥ 3 cm, lower segment involvement, poorly differentiated pathology, deep stromal invasion, pelvic lymph node, lympho-vascular involvement and positive surgical margin (all p values < 0.05). Among these variables only tumor size ≥3 cm (OR: 2.1, 95% CI: 1.11-4.16, p value: 0.02), deep stromal invasion (OR: 2.2, 95% CI: 1.9-7.43, p value: 0.02) and positive surgical margin (OR: 5.1, 95% CI: 3.97-11.15, p value: 0.008) were independent risk factor of PI in multivariate analysis. Conclusions: Early stage CC might be surgically approached in a more conservative manner if patients have tumor size <3 cm and do not have deep stromal invasion in conization.
RESUMEN
INTRODUCTION AND IMPORTANCE: Struma ovarii is a monodermal teratoma which characterized by the presence of thyroid tissue. The symptoms of this tumor are nonspecific and thus misdiagnosis and indifference to other ovarian lesions are very common. CASE PRESENTATION: Herein, we described a case of struma ovarii that was successfully diagnosed and managed. The tumor is mimicking a malignant tumor based on ascites and tumor marker assessments. Although, thyroid function indices are normal. CLINICAL DISCUSSION: The initial footprint of the tumor is mostly based on incidental imaging, but definitive diagnosis is possible based on pathological studies. Surgical resection of the tumor can be led to successful treatment and prognosis. CONCLUSION: Struma ovarii is a rare tumor and also misdiagnosis is common. Regarding rarity of Struma Ovarii, the treatment option is debated. However, in postmenopausal cases with the aim of completely removing the symptoms, total abdominal hysterectomy with bilateral salpingo-oophorectomy can be occasionally indicative.
RESUMEN
BACKGROUND: This study aimed to investigate the potential relationship between diffusion kurtosis imaging (DKI)- derived parameters and lymphovascular space invasion (LVSI) in patients with cervical carcinoma. PATIENTS AND METHODS: This prospective study included 30 patients with cervical carcinoma. The patients underwent MRI, diffusion-weighted imaging (DWI), and DKI prior to surgery. The surgical pathology results were accepted as the reference standard for determining the LVSI status. The DKI-derived parameters, including mean diffusivity (MD) and mean kurtosis (MK), were measured. The apparent diffusion coefficient (ADC) value was also assessed. RESULTS: The MD value of LVSI positive cervical carcinomas was significantly lower than LVSI negative carcinomas (p-value = 0.01). MK value was significantly higher in LVSI positive tumors (p-value = 0.01). However, the ADC value did not show a significant difference between LVSI positive and LVSI negative tumors (p-value = 0.2). MD and MK parameters showed similar diagnostic accuracy in identifying the LVSI status, with the area under the curve of 0.77 and 0.78, respectively. CONCLUSION: In this study, DKI-derived parameters were associated with the LVSI status in cervical carcinomas. Further studies with larger sample size are required to confirm these results.
