RESUMO

Introduction: COVID-19 prognostic risk factors, therapeutic protocols, and clinical outcomes in pediatric cases are still under investigation. Materials and Methods: This historical cohort study evaluated the survival time of hospitalized children (1 month-18 years old) with COVID-19 admitted from March 2020 to August 2021 to an educational hospital in Yazd, Iran. The follow-up of patients was performed at least one month after discharge. Results: From 183 hospitalized cases, 24 children were deceased. The median age of patients was 5.41, and 54.2% were male. The survival rate after one-month follow-up was 0.88, and the most significant predictors associated with survival time were the male sex, positive history of hospitalization, lymphopenia, hypoxia, and length of stay more than two weeks using Bayesian Cox regression analysis. Conclusion: Accurate estimation of the impact of predictors on poor outcomes may help healthcare providers use therapeutic protocols based on risk factors and healthcare requirements of each patient to improve their survival.

RESUMO

Introduction: The study aims to investigate the characteristics, comorbidities, laboratory findings, and clinical manifestations of under 18-year-old patients who died with the diagnosis of COVID-19 and determination of the most prevalent risk factors. Method: This case-control study was performed at a referral hospital in Yazd from March 2020 to August 2021. All patients under 18 years who were diagnosed through real-time RT-PCR, chest computed tomography, and the World Health Organization definition were divided into deceased and survived groups. The characteristics (age and sex), disease severity, comorbidities, laboratory findings, and clinical manifestations of the two groups were compared and analyzed using SPSS, version 18 (SPSS Inc., Chicago, III., USA). Results: A total of 24 patients in the deceased group and 167 patients in the survived group were compared. The highest mortality rate was observed in the age group of 1 month to 5 years, although no statistically significant relationship was found between age groups and the risk of mortality. Disease severity, dyspnea, low oxygen saturation on admission, length of hospital stays, and hospitalization history before the last admission were significantly correlated with mortality (P < 0.05). Lymphopenia increased the probability of mortality by more than two times (OR: 2.568; 95% CI (0.962-6.852)), but this was not the case for D-dimer and C-reactive protein. Furthermore, 27.5% of survived patients had normal chest CT scans, which was a statistically significant difference compared to the deceased patients (P: 0.031). Conclusion: Based on the findings of this study, dyspnea, low oxygen saturation, and lymphopenia are critical indicators for identifying high-risk children with COVID-19 and triaging them for better care and treatment.

RESUMO

Sperm processing for assisted reproductive technologies (ART) aims to separate immotile and debris from the motile spermatozoa in the semen. The purpose of this study was to assess the effect of free centrifuge sorting (FCS) approach based on a combination of rheotaxis and swim-up on sperm biological characteristics and ICSI clinical outcomes. Each semen sample was splitted into two equal parts for 67 ICSI cycles with donation oocytes. Parts were processed with the Direct Swim Up (DSU) (control) and with the FCS method (experimental). Sperm quality was assessed in terms of motility, fine morphology, mitochondrial membrane potential, lipid peroxidation and sperm DNA fragmentation. Also Following ICSI, the clinical outcomes were compared between the groups. Sperm progressive motility (93.5 ± 4.1% vs. 78.6 ± 8.2%; p < 0.001), the fraction of Class I (good) morphology (30.2 ± 9.4% vs. 23.7 ± 8.5%; p < 0.0001) and the rate of mitochondrial membrane potential (77.4 ± 7.2% vs. 66.9 ± 5.7%; p < 0.0001) were significantly higher in the FCS compared to DSU groups. The level of lipid peroxidation (0.5 ± 0.05% vs. 0.6 ± 0.06%; p < 0.0001) and concentration of DNA fragmentation (DF) (7.4 ± 1.6% vs. 15.4 ± 2.6%; p < 0.0001) were lower in sperm from the FCS group compared to DSU group. There were higher rates of high-quality embryo formation (p < 0.001), implantation and clinical pregnancy rates (p = 0.03) in the FCS group compared to the control group. The processing of seminal samples using FCS collected spermatozoa with better biological quality and resulted in higher reproductive outcomes in ICSI cycles.

RESUMO

In this study, a Bayesian approach was suggested to estimate a change-point according to a covariate threshold when some patients never experienced the event of interest. Gibbs sampler algorithm with latent binary cure indicators was used to simplify the implementation of Markov chain Monte Carlo method. Then, the accuracy of new model was demonstrated by simulation studies to compute the point and interval estimates of parameters. Finally, an effective threshold was suggested in age at surgery time to experience the metastasis when the model was applied for a data set of breast cancer patients.

RESUMO

Background: Hypoxic-ischemic encephalopathy (HIE), caused due to reduced oxygenation and brain blood flow, occurs in 1-8 per 1000 live full-term births in developed countries and up to 26 per 1000 live in the developing world. The growth status of survivors of birth HIE has not been evaluated sufficiently. Objective: This study evaluated, the growth parameters (weight, height, and head circumference) of neonates with Sarnat stage.2 of HIE at 6, 10, and 12 months and its relationship with findings of neonatal brain diffusion-weighted imaging (DWI) sequence. Materials and Methods: Medical records and growth parameters of 35 neonates with gestational age > 34 wk who were admitted with stage.2 of HIE in Neonatal Intensive Care Unit of Shahid Sadoughi hospital, Yazd, Iran from March 2021-March 2022, and its relationship with neonatal brain DWI sequence finding was evaluated. Results: 15 girls and 20 boys with a mean birth weight of 2880.3 ± 221.8 gr were evaluated. Conventional magnetic resonance imaging and DWI were found to be abnormal in 6 (17.1%) and 18 neonates (51.4%). The most abnormal finding of DWI was high signal in basal ganglia/thalamus in 9 neonates (25.7%). Abnormal DWI is more frequent in neonates with seizures and low birth weight. Hospital stay days were more prolonged in neonates with abnormal DWI. Microcephaly at 12 months was more frequent in children with abnormal DWI. Conclusion: In survivors of moderate neonatal HIE, abnormal brain DWI sequence might predict inappropriate head growth, and need close medical and nutritional interventions for growth improvement.

RESUMO

Background: Individualized assisted reproductive techniques (ART) can improve ART outcomes. Some studies suggested using insulin-like growth factor-1 (IGF-1) level on cycle day 2 for individualized ART. Objective: To investigate the relationship between serum levels of IGF-1 on day 2 of the cycle and ART outcomes. Materials and Methods: In this cross-sectional study, cycle day 2 serum levels of IGF-1 were measured in 175 women aged between 18-44 yr as candidates for in vitro fertilization or intracytoplasmic sperm injection. All participants received antagonist protocol, and the relationship between serum levels of IGF-1 and ART outcomes according to the number of oocytes were investigated; poor responders (oocytes < 5), normal responders (oocytes 5-15), and hyper responders (oocytes > 15). Results: Poor responders had higher serum level of IGF-1 when compared with normal and hyper-responders; however,this difference was not statistically significant (p = 0.41). The serum levels of IGF-1 in women with zero retrieved oocytes and those cycles that were canceled for the inappropriate ovarian response were not significantly different compared to other women in the group of poor responders. An inverse relationship was observed between the serum level of IGF-1 and anti-Mullerian hormone. Furthermore, no significant relationship between serum level of IGF-1 with age, body mass index, number of 2 pronucleus, and number of embryos was observed. Conclusion: According to our results, the serum levels of IGF-1 may not be able to predict ART outcomes. It seems necessary to conduct more studies with larger sample size.

RESUMO

Background: Endometriosis is a female reproductive system disease in which the endometrial tissue is found in other women's organs. Various factors are effective in the development of endometriosis, and because of the interaction of genetics and environmental factors, this disease is a multi-factorial disease. MAPK/ERK and PI3K/Akt/mTOR pathways are activated by growth factors and steroid hormones and are known as two important pathways involved in the processes of growth, proliferation, and survival of endometriosis cells. Raps, monomeric GTPase of the Ras family, are able to activate these pathways independent of Ras. The goal of our study was to evaluate the expression level of Rap1GAP and EPAC1 genes as two important RapGAPs (GTPase-activating proteins) and RapGEFs (guanine nucleotide exchange factors), respectively, in endometriosis tissues and normal endometrium tissues. Materials and Methods: In this study, 15 samples of women without signs of endometriosis were taken as control samples. Fifteen ectopic and 15 eutopic samples were taken from women with endometriosis using laparoscopic surgery. The expression of EPAC1 and Rap1GAP genes was investigated by the real-time polymerase chain reaction technique, and the results were analyzed by one-way ANOVA test. Results: EPAC1 upregulated significantly in ectopic tissues compared to eutopic and control tissues. Rap1GAP expression was lower in ectopic tissues compared to control and eutopic tissues. Conclusions: Based on these results, it may be concluded that changes in the expression of the Rap1GAP and Epca1 genes may play a role in the pathways involved in the pathogenesis, displacement, and migration of endometriosis cells.

RESUMO

Background: Endometrios affecting 6-10% of women of reproductive ages around the globe. Important pathways, including the MAPK and PI3K / Akt pathways, have been identified in the disease. The NF1 and RASA1 genes inactivate Ras by their own GTPase activity and controlled the high activity of these pathways. Objective: In this study, we measured NF1 and RASA1 gene expression in the endometrial tissues of patients (eutopic and ectopic tissues) compared to the control samples. Materials and methods: In our study, tissue samples were collected from 15 patients with endometriosis and 15 healthy women. We used quantitative polymerase chain reaction (qRT-PCR) to measure the NF1 and RASA1 gene expression levels in these samples. Results: We observed a significant decrease in the expression level of the NF1 gene in both eutopic and ectopic samples of endometriosis patients compared to control samples, while the expression of the RASA1 gene was significantly reduced only in ectopic tissues.

RESUMO

Introduction: Chronic neck pain is a common complaint among office workers. The aim of the present study was to compare the efficacy of a high-intensity laser and physiotherapy in office workers who were diagnosed with chronic non-specific neck pain. Methods: This study was a single-blind randomized controlled trial, with parallel allocation. Sixty office workers with chronic neck pain, aged between 25 and 55 years, participated in the study. The participants were randomly divided into two groups: photobiomodulation (by a high-level laser) and physiotherapy. Visual analogue scale (VAS), Neck Disability Index (NDI), Neck Pain and Disability Scale (NPDS) and Bournemouth Questionnaire (BQN) were completed on three occasions (before, immediately and 2 weeks after the intervention) to assess and compare the efficacy of the high-intensity laser and physiotherapy in neck pain. Data were analyzed by SPSS 23 software using the chi-square test, Student's t test, multivariate tests, and Fisher's exact test. Results: The mean age of the participants was 37.53±9.52 and 41.16±7.85 years in physiotherapy and laser therapy respectively. The VAS score and NDI scores decreased after both kinds of interventions, and the effect of photobiomodulation was significantly higher than physiotherapy (P < 0.001). Both treatment modalities significantly affect different aspects of chronic neck pain assessed by NDPS and BQN questionnaires and the effect of photobiomodulation was more prominent than physiotherapy. Conclusion: The findings of this study showed that photobiomodulation and physiotherapy can reduce chronic neck pain and its different aspects and the effect of laser therapy was significantly higher than physiotherapy.

RESUMO

Textural, physicochemical, and sensory characteristics of rice-based gluten-free bread in the presence of acorn flour; inulin and different fermentation type (yeast starter fermentation [Y] or mixed fermentation based on sourdough [MF-SD]) were investigated. Acorn flour was added to replace rice flour at a proportion of 10, 30, and 50% W/W. Furthermore, the mixture flour was replaced by inulin as a functional prebiotic ingredient at 10% W/W. Considering results obtained at this study, using mixed fermentation based on sourdough and inulin at 10% W/W provide the structure able to restore gases through baking process at formulations containing acorn flour at 30% W/W (A30R70SL). The highest specific volume (1.47 ± 0.04 cm3 g-1) and the lowest hardness (40.97 ± 0.87 N) are observed in A30R70SL which seems to be induced by its potential to form gel. Acorn flour substitution level at 50% W/W adversely influenced the technological characteristics of final product and its perception by the consumer. Acorn flour substitution up to 30% W/W is preferred by the consumer which is attributed to its potential role to improve the unpleasant pale color of rice-based gluten-free products. A negatively significant correlation has been observed between the color perception by the consumer and crumb lightness (r = -.493, p ≤ .05).

RESUMO

BACKGROUND: The purpose of this study was to determine the prevalence of musculoskeletal complaints, rheumatologic diseases, and disability among the Zoroastrian population in Iran. METHODS: The city of Yazd, in central Iran was selected for this study, with the highest population of Zoroastrians in Iran. Subjects were selected by cluster sampling of 9 neighborhoods populated with Zoroastrians. Subjects ≥15 years old were interviewed by trained interviewers in their houses. The validated Farsi translation of Community Oriented Program for the Control of Rheumatic Disease (COPCORD) Core Questionnaire (CCQ) was used for this study. Subjects with musculoskeletal complaints (pain, stiffness and/or swelling) were examined by a rheumatologist. Laboratory tests and radiographic exams were performed when deemed necessary. RESULTS: Two-thousand subjects were interviewed during a 12-month period, of which 956 were male, and 1044 were female. The mean age was 41.1 ± 18.3 years (95%CI: 40.3-41.9). 36.9% of the subjects had university-level education. In the 7 days prior to the interview, 27.6% of the subjects had musculoskeletal complaints, with the knee, dorsolumbar spine, and shoulder being the most common sites of complaints. The most common rheumatologic diagnoses were osteoarthritis (21.5%) and low back pain (10.3%). Rheumatoid arthritis was diagnosed in 1.2% of the subjects. CONCLUSIONS: The epidemiology of musculoskeletal complaints and rheumatologic disorders was inconsistent with previous COPCORD studies in Iran, with a lower prevalence of musculoskeletal complaints in general, lower rates of Behçet and lupus, and a higher prevalence of rheumatoid arthritis. The findings of this study can be for development of better prevention, screening, and treatment programs for the vulnerable population of Zoroastrians in Iran.

RESUMO

BACKGROUND: Pregnancy is a process associated with various metabolic and hormonal changes, and polycystic ovary syndrome (PCOS) can affect this process. OBJECTIVE: This study aimed to evaluate and compare the maternal and neonatal outcomes among pregnant women with different polycystic ovary syndrome phenotypes. MATERIALS AND METHODS: In this cross-sectional study, 200 pregnant women with PCOS according to the 2003 ESHRE/ASRM criteria were categorized into four phenotype groups (A-D). The maternal outcomes include gestational diabetes mellitus, pregnancy-induced hypertension, premature rupture of membranes, preterm labor, small-for-gestational age birth, intrauterine growth restriction, intrauterine mortality, preeclampsia, abortion, amniotic fluid disorders, delivery method, and cause of cesarean section were studied between groups. Additionally, neonatal outcomes such as neonatal weight, neonatal recovery, 5-min Apgar score, neonatal icter, the need for NICU admission, the cause of hospitalization, and infant mortality rate were investigated and compared among the groups. RESULTS: According to the results, phenotype D (37%) was the most common phenotype among the participants. The risk of gestational diabetes was more common in phenotype A than in the other phenotypes, whereas pregnancy-induced hypertension was most common in phenotype B. No significant differences were observed in the neonatal complications among the PCOS phenotypes. CONCLUSION: Considering the higher risk of gestational diabetes mellitus and pregnancy-induced hypertension in PCOS phenotypes A and B, women with these phenotypes need more precise prenatal care.

RESUMO

Objective: The purpose of this study was to evaluate the long-term outcome of endometrial ablation (EA) therapy with Cavaterm Thermal Balloon in patients with abnormal uterine bleeding (AUB). Material and Methods: The retrospective cross-sectional study was performed on 209 patients who referred to Shahid Sadoughi Hospital in Yazd, Iran between March 2010 and September 2017 with AUB undergoing EA therapy. The data was collected by a questionnaire from the medical records of patients and phone call. The primary and secondary outcomes post EA therapy (from six months to seven years post-operatively) were assessed in patients. Results: The mean age of participants was 45.9±5.9 years and the mean follow-up duration was 21.2±13.2 months. The rate of treatment response was 95% in the first six months and 92.1% thereafter. The prevalence of amenorrhea was 41.2%. The patient satisfaction rate at the end of follow-up duration was 81.3%. Dysmenorrhea completely resolved in 32.6%. Moreover, 1.4% of patients became pregnant during follow-up. By the end of follow-up, four (1.9%) patients had a hysterectomy due directly to treatment failure. Conclusion: This study showed that EA surgery with Cavaterm Thermal Balloon was an effective treatment for AUB. The procedure was safe and was associated with a very low rate of postoperative adverse events. The patient satisfaction rate was favorable.

RESUMO

INTRODUCTION: Exposure to high intensity noise produced by MRI is a cause for concern. This study was conducted to determine the temporary and permanent effects of exposure to noise created by performing MRI on the hearing threshold of the subjects using conventional and extended high frequency audiometry. METHODS: This semiexperimental study was performed on 35 patients referred to Shahid Rahnemoun Hospital for head and neck MRI due to different clinical conditions. The hearing threshold of patients was measured before, immediately after, and 24 hours after performing 1.5 Tesla MRI using conventional and extended high frequency audiometry. SPSS version 18 was used to compare the mean hearing thresholds before and after MRI using paired T test and repeated measures analysis. RESULTS: Comparison of auditory thresholds in conventional and extended high frequencies before and immediately after MRI showed a significant shift at 4 KHz (P = 0.008 and P = 0.08 for right and left ears), 6 KHz (P = 0.03 and P = 0.01 for right and left ears), and 14 KHz (P =0.03 and P = 0.31 for right and left ears). However, there was no significant difference between audiometric thresholds before and 24 hours after MRI. CONCLUSION: Noise due to 1.5 Tesla MRI can only cause transient threshold shift.

RESUMO

This is a randomized, double-blind, clinical/comparative trial study, involving the recurrence of vaginal candidiasis (VVC) after initial treatment with oral fluconazole in patients undergoing prophylactic management with a probiotic and placebo for 6 months. Fifty-nine VVC patients who were diagnosed based on their history, physical examination, and culture of vaginal discharge were initially treated by a single dose of 150 mg fluconazole. According to the table of random numbers, the sample was divided into two groups. The patients from one group took probiotics, while those from the other group took a placebo, with all of them being continuously monitored for 6 months. The patients complaining of vaginal candidiasis symptoms, such as burning, pruritus, and a vaginal (curd-like) discharge, were examined and the discharge was cultured for candida. The positive cultures were considered to be recurring for the patients in each group. Thirty-one cases from the placebo group and 28 cases from the probiotic group were carefully observed. In total, the 6-month recurrence in the control group was eleven (35.5 %) and in the research group was two (7.2 %). The results from Fisher's exact test for the value p = 0.01 and OR 0.14 95 % CI (0.028-0.7) showed significant recurrence in the placebo group. The findings demonstrated that taking probiotics withazole antifungal drugs could be highly effective in treating VVC, resulting in a lower recurrence rate as well.

RESUMO

BACKGROUND: Chest pain is a common symptom for referring patients to emergency departments (ED). Among those referred, some are admitted to hospitals with a definite or tentative diagnosis of acute coronary syndrome and some are discharged with primary diagnosis of non-cardiac chest pain. This study aimed at investigating 30 days' adverse outcomes of patients discharged from ED of a major heart center in Iran. METHODS: Out of 1638 chest pain admissions to the centre during 2010-2011, 962 patients (mean age= 50.9±15.9 years) who were admitted to Afshar Heart Center's ED with chest pain as their chief complaint, and discharged with primary diagnosis of non-cardiac chest pain, were followed for any adverse cardiac events 30 days post discharge. The adverse events were: unstable angina, non-ST-elevated myocardial infarction (NSTEMI), ST elevated myocardial infarction (STEMI), coronary revascularization (percutaneous angioplasty, coronary artery bypass grafting) and death. RESULTS: Adverse cardiac events, including acute coronary syndrome (ACS), revascularization and death were observed in 30 patients (3.1%) including: acute MI n=5 (0.5%, sudden cardiac death inn=1 (0.1%, coronary revascularization in n=8 (0.8%) and hospitalization due to unstable angina/NSTEMI in n=16 (1-7%). Adverse events were seen more frequently in patients with history of hypertension, dyslipidemia and previous coronary artery disease. In univariate analysis, the chance of postdischarge adverse cardiac events was higher in patients with hypertension (OR=9.36, CI=3.24-27.03), previous coronary artery disease (OR= 3.8, CI=1.78-8.0), dyslipidemia (OR=3.5, CI=1.7-7.38) and discharge against medical advice (OR=2.85, CI= 1.37-5.91). CONCLUSION: The extent of adverse cardiac events in patients with a primary diagnosis of non-cardiac chest pain within 30 days of discharge was significant, mandating nation-wide registries to provide better care for these patients.

RESUMO

BACKGROUND: It has been suggested that Vitamin D and calcium have protective effects against breast cancer. The results about breast cancer and serum Vitamin D and calcium levels are still controversial, indefinite, and insufficient to determine the amount of nutritional needs. Thus, we investigated the association between serum 25-hydroxyvitamin D(25-OH-D) and calcium on the ratio of breast cancer at diagnosis time. MATERIALS AND METHODS: We carried out a hospital-based cross-sectional study in a population of Iran. It comprised 57 breast cancer cases, who were newly diagnosed, and 85 controls in 2013. The serum 25-OH-D and calcium levels were measured. RESULTS: There was not any significant association between 25-OH-D and breast cancer ratio. Odds ratio (OR) comparing the highest quartile to the lowest quartile was 1.03(95% confidence interval[CI] 0.33-3.22, P-trend 0.95). Having sufficient (>75 nmol/L) serum 25-OH-D levels compared to insufficient serum 25-OH-D levels was not associated with a significantly decreased ratio of breast cancer (OR 0.55, 95% CI 0.23-1.29, P = 0.17). Furthermore, an association between calcium and breast cancer did not get statistical significance (OR 0.51, 95% CI 0.17-1.49, P-trend 0.31). The joint effect was negative interaction. CONCLUSION: Vitamin D and calcium do not act on decreasing ratio of breast cancer. Decreasing ratio of breast cancer in relation to serum calcium and Vitamin D level at diagnosis time needs more assessments.

RESUMO

To evaluate the clinico-pathological and survival characteristics in patients with bone metastasis. This cross-sectional study was conducted on patients with bone metastasis who referred to Shahid Ramezanzadeh radiation oncology center. For all of the patients studied, demographic and survival information was recorded. SPSS was used to analyze the data. In this study, 89 men (53.3%) and 78 women (46.7%) with bone metastasis were examined. Most of the patients were in the 66 to 87 age range. Breast cancer was the most common type of cancer in women and prostate cancer was the commonest in men. In most patients, pain was the first manifestation of the disease, and the spine has been most frequently involved areas. The disease was diagnosed by isotope bone scan in the most cases. The mean survival was 31.1 months for patients with breast cancer, 12.9 months for patients with prostate cancer, 13.7 months for patients with lung cancer and the overall survival was 22.5. There was only a meaningful correlation between sex, type of cancer, radiation dose, and survival in patients. We found that age was more effective than the variable of cancer type in survival of patients with bone metastasis. The prognosis of patients with bone metastasis in our center is fair. There was a significant correlation between sex, type of cancer, radiation dose, and survival. Cox proportional hazards model showed that age was a predictor of death.

RESUMO

BACKGROUND: Clinical governance is a systematic approach to maintaining and improving the quality of patient care. This study aimed to assess some Iranian educational hospitals' readiness for clinical governance implementation through the organizational climate. METHODS: It was a cross-sectional study that used the Clinical Governance Climate Questionnaire (CGCQ) in three educational hospitals in Yazd, a city in central Iran, in 2012.
