- ItemComparison of Word Complexity and Speech Intelligibility in Deaf Children with Cochlear Implant and Hearing Aids(Brieflands, 2025-01-31) Mohammad Rezaei; Solmaz Mehrfar; Farzad WeisiBackground: Most people with profound hearing loss have problems in speech intelligibility that related to their phonological ability and linguistic skill. The objectives of this research are to assess the clarity of speech and the complexity of words in children with hearing impairments who use cochlear implants (CI) and those who use hearing aids (HA). Objectives: Additionally, it aims to explore the connection between speech clarity and word complexity in these children. Methods: A total of fifty children with hearing loss (average age = 4.5 ± 0.8 years) were divided into two equal groups: One group consisting of 25 children with CI and another group with 25 children using hearing aids. Speech intelligibility of participants was evaluated by the repetitive word list. The criterion for examining the word complexity was the syllable number of each word. Results: The results showed that the CI group had better speech intelligibility than the HA group. There is a significant positive correlation between word complexity and speech intelligibility in hearing impaired children (P < 0.001). Conclusions: According to the results of this study, the CI children showed better speech intelligibility than HA because of the effectiveness of implantation on auditory input. On the other hand, the word complexity also contributes to the level of speech intelligibility. Therefore, experts working in the field of management and clinical education of these children need to consider the word complexity and other factors affecting the speech intelligibility.
- ItemAssessing of the Anxiety Level of COVID-19 and Its Relationship with the Demographic Variables of Pregnant Women: A Cross-Sectional Study(Brieflands, 2025-01-31) Samaneh Tahmasebi Ghorabi; Arian Karimi Rouzbahani; Masoumeh Ghafarzadeh; Mojgan Kaviani; Banafsheh Derikvand; Azin Niazi; Fatemeh YariBackground: The current and alarming situation of the COVID-19 pandemic may cause anxiety in pregnant women. Objectives: Given the importance of both physical and mental health for expectant women, this study investigated COVID-19 anxiety among pregnant women referred to Asalian Hospital in Khorramabad during 2021 - 2022. Methods: This descriptive cross-sectional study was conducted among pregnant women referred to Asalian Hospital in Khorramabad. A total of 253 pregnant women were included in the study based on the study criteria and the available sampling method. The Corona Virus Anxiety Scale was used to collect data through a questionnaire. The data were analyzed using SPSS version 22, and analysis of variance (ANOVA) and t-tests were employed to examine the data, with the significance level set at 0.05. Results: The mean age of expectant women was 27.7 ± 3.56 years. The average anxiety score among the pregnant women was 4.39 ± 3.99, with physical and mental dimension scores of 1.67 ± 1.89 and 2.71 ± 2.15, respectively. There was a statistically significant difference in the average anxiety scores related to COVID-19 based on education, place of residence, and the number of pregnancies (P < 0.05). Conclusions: The present study found that pregnant women experienced a low level of anxiety in response to COVID-19. The average score for the psychological aspect of COVID-19-related anxiety among these women was greater than that for the physical aspect. Therefore, by increasing public awareness about COVID-19 and providing positive psychological programs in the media aimed at managing stress, anxiety in pregnant women can be effectively reduced.
- ItemInvestigating The Synergistic and Antimicrobial Effect of Glycolipid Biosurfactants Produced by Shewanella alga 12B and Bacillus pumilus SG Bacteria with Thyme Plant Extract on Some Pathogenic Bacteria(Brieflands, 2024-10-31) Arezou Rezaee; Fatemeh Bazzi Allahri; Pooya Samian; Seyed Mostafa Ghasemi Najarkolaee; Reza Yusofvand; Tahereh Eslam-Manesh; Mehdi HassanshahiBackground: Thyme is widely recognized for its antimicrobial properties, attributed to the effective compounds present in its extract that inhibit and destroy pathogenic bacteria. Objectives: This study explores the impact of combining thyme extract with biosurfactants on pathogenic bacteria and biofilm. The biosurfactants 12B and SG have inherent antimicrobial effects, and their combination with thyme extract demonstrated synergistic effects. Methods: The experiments involved preparing methanolic thyme extract in combination with biosurfactants 12B and SG. Disk diffusion and well diffusion tests were conducted to assess the antimicrobial activity of this combination. The inhibition zones for Acinetobacterbaumannii, Bacilluscereus, Escherichiacoli, and methicillin-resistant Staphylococcusaureus (MRSA) were measured. Further tests determined the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for these bacteria. To evaluate synergistic effects, the fractional inhibitory concentration (FIC) and fractional inhibitory concentration index (FICI) were calculated. Results: The anti-biofilm effects of the biosurfactants combined with thyme extract were analyzed by testing biofilm formation inhibition, biofilm destruction, and inhibition of dehydrogenase enzyme activity within the biofilm. Biofilm assays were conducted using microplates, with readings taken at 490 nm using an ELISA reader. Conclusions: The biofilm tests demonstrated the effectiveness of thyme extract combined with biosurfactants. The results indicated that this combination exhibits antibacterial, anti-biofilm, and synergistic effects, making it effective against both antibiotic-resistant and non-resistant pathogenic bacteria.
- ItemAssessing four different methods of taper on athletes hematological responses(Brieflands, 2004-03-31) AR Asgari Ashtiani; Mehdi Mohammadi; Ramin Saravani; Mohsen TaheriBackground: In serious competitions in order to keep the acquired fitness, athletes are advised to reduce the exercise intensity before starting the races. This technique is called taper. The purpose of this study was to compare four usual procedures of Taper and effect of them on the Hematological responses by measuring Vo2 max, hematological and biochemical factors. Methods and materials: Sixty semi professional athletes, 20 to 35 years old with Vo2 max between 30-45 three milts/kg/min were selected. Exercises were in three stages and took for eight weeks. In the first stage, which lastd for 4 weeks athletes did moderate intensity exercise three days a week and 30 minutes a day. Second stage started after the first stage with vigorous exercise three days a week and 45 minutes a day that lasted for two weeks. In the third stage taper, the subjects were randomly divided into four groups. The program of the first group was two days week and exercise intensity so was done with 85%, 75%, 65% and 55% of maximum exercise intensity. Second group program was two days a week exercise with 50% of maximum exercise intensity. The third group program was two days a week exercise with gradual reduction of exercise intensity. The fourth group had only rest. At second and sixth weeks after doing progressive exercise and taper, blood samples were taken from the cases and were sent to a reliable diagnosis lab. Results: Collected data from different taper methods were analyzed using repeated measures ANOVA and no significant difference between biochemical factors (P>0.05) was seen but the data showed a significant difference among Vo2 max values after using theses methods (P=0.04). In addition, there was significant difference in hemoglobin, hematocrit, M.C.H, M.V.C, platelets, W.B.C and Vo2 max when measured in second week, sixth week and later on Taper (P

- ItemThe Comparison of Pain Relief between Postoperative Wound Infiltration with Bupivacaine 0.5% Combined with Epinephrine after Elective Cesarean Section(Brieflands, 2013-04-30) vida modarres nejad; batool Motamedi; Mazyar NafisyBackground : So many methods have been developed and tested to control post-surgical pain. In this study, the effect of bupivacaine-H medicine (along with epinephrine) on the post-surgical pain reduction in cesarean mothers was examined.Materials and Method s: In a double blind randomized clinical trial study conducted in Kerman, 70 pregnant women who were eligible for elective cesarean section participated in the study as randomized into two case and control groups. In all the patients, cesarean section incision lengths were equal and bupivacaine was injected after infant delivery. In the control group, physiological serum was used as placebo instead of medicine. Pain severity was compared between two groups using Visual Analogue Scale (VAS) on 6, 12, 24 and 48 hours after operation. The results were analyzed applying SPSS-11 software and using Mann-Whitney U and Wilcoxon tests.Results : Mean age of the patients was 25.36 years with standard aviation of 2.48 years and the age range of 18-28 years. A previous cesarean with relative frequency of 38.5 percent was the main cause of cesarean section in such patients. In the case group, pain severity before 24 hours was less than that in the control group. After 24 hours of the operation, the pain severity in both case and control groups were similar.Conclusion : In general, bupivacaine injection into the cesarean incision area will cause to reduce the pain after cesarean section in the mothers and considering its minor complications, such medicine may be used as an effective pain control method in women.
