Abstract
Background: Recently, epinephrine is used to increase the depth and duration of local anesthetic pain, and it is widely used topically to reduce local anesthetic release and reduce bleeding caused by surgery.
Methods: This study was a randomized, double-blind clinical trial on 30 patients aged 18 to 85 years undergoing lower limb orthopedic surgery referred to Peymaniyeh Hospital in Jahrom from September to December 2022. Patients were randomly assigned to two groups, A (epinephrine+fentanyl+bupivacaine) and B (bupivacaine+fentanyl). Systolic blood pressure, diastolic pressure, mean arterial pressure, arterial blood oxygen saturation percentage, and pulse rate were measured and recorded before drug administration, before spinal anesthesia, after anesthesia, and then every half hour until the end of surgery (15, 45, 30, 60, 75, 90, 120) and during recovery. Data analysis was performed using SPSS version 21 software and descriptive (mean, standard deviation) and inferential statistics (t-test, chi-square, Mann-Whitney, Friedman) at a significance level of P<0.05.
|
Results: Thirty patients aged 18 to 85 years (in two groups of 15) with anesthesia class I and II undergoing lower limb orthopedic surgery were evaluated. The study groups are matched in terms of age and gender variables. There was no significant difference in mean systolic, diastolic, mean arterial blood pressure, and heart rate before and after anesthesia, 15, 45, 30, 60, 75, 90, and 120 minutes after drug injection, and at entry and exit from recovery between the Epinephrine+Fentanyl+Bupivacaine and Fentanyl+Bupivacaine groups. There was a significant difference in mean O2SAT before anesthesia, 15, 30, and 75 minutes after drug injection between the epinephrine+fentanyl+bupivacaine and fentanyl+ bupivacaine groups (P<0.05).
Conclusion: The use of the combination of epinephrine+fentanyl+intrathecal bupivacaine compared to the combination of fentanyl+bupivacaine did not have a significant difference in the studied variables of patients' vital signs.

Abstract
Background: Rhinoplasty is a challenging and complex surgery because it is designed to meet the unique needs of the patient. In rhinoplasty surgery, many factors contribute to achieving the desired result. These factors include the surgeon's care and observation, analysis of the existing anatomy, choice of surgical technique, degree of soft tissue and cartilage trauma, amount of bleeding, quality of surgical instruments and anesthesia, and anything that helps reduce bleeding.
Methods: This double-blind study was conducted on 50 patients aged 18 to 45 years undergoing septorhinoplasty surgery referred to Motahari Hospital in Jahrom city in 2022. Patients were randomly divided into dexmedetomidine and control groups. The degree of sedation, bleeding and surgeon satisfaction were evaluated and recorded. Data analysis was performed using SPSS software, version 21 (IBM SPSS, Armonk, NY, USA) and descriptive statistics (mean, standard deviation, percentage, number, frequency) and inferential statistical tests (Mann-Whitney U test, Kruskal-Wallis, t-test, chi-square test). The significance level in all tests was considered P<0.05.
|
Results: The majority of patients in the study groups were female and the mean age of patients in the dexmedetomidine group was 34.36±7.33 years and in the control group was 36.60±9.59 years. The study groups were similar in terms of age and body mass index (P<0.05). The frequency of patient sedation in the dexmedetomidine group was lower than the control group, but it was not statistically significant (P<0.05). The results showed that at the beginning of the operation and 90 minutes later, the satisfaction level of the patient surgeon in the dexmedetomidine group was significantly better than the control group (P<0.001). In the dexmedetomidine group, the field of view of the surgeon was relatively clear and completely clear. The amount of bleeding in the dexmedetomidine group was lower than the control group, but it was not statistically significant (P<0.05).
Conclusion: Dexmedetomidine increased the surgeon's satisfaction by reducing bleeding and improving the surgeon's visual field. Therefore, this drug can be used as an anesthetic aid in surgery.

Abstract
Background: Sarcopenia is the degenerative loss of skeletal muscle mass, which is known as a poor postoperative outcome in various cancer types. Radical cystectomy (RC) is often associated with high mortality rates, and sarcopenia is hypothesized to aid in risk stratification. Hence, this study assessed the role of Sarcopenia as an indicator of postoperative outcomes and survival rates in patients undergoing RC for bladder cancer.
Methods: This cross-sectional research was carried out between January 2022 and January 2023 on 30 patients with bladder cancer who were candidates for RC and referred to the urology clinic of Imam Khomeini Hospital in Tehran. One week before surgery, the cross-sectional area of the psoas muscle was measured using MRI to estimate muscle volume, and the sarcopenia index was calculated. Muscle area evaluation was performed by calculating the cross-sectional area of the left and right psoas muscles on MRI. The psoas muscle area was calculated by excluding blood vessels, bony structures, and intermuscular fat regions based on fat signals. The calculated psoas muscle area was then normalized to the patient's height in square meters. To improve the quality of reporting on surgical complications, the patients were re-examined and the duration of patients' hospital stays was measured.
Results: The mean sarcopenic index for the patients was 1264.6 ± 591.5 mm²/m². Seven patients (24.1%) were smokers, while 22 patients (75.9%) were non-smokers. During the 10-month follow-up period, 25 patients (83.3%) remained alive, and 5 patients (16.7%) passed away. The mean value of sarcopenic index in patients with localized cancer was higher than those with advanced cancer, but this difference was not statistically significant. Data analysis revealed a significant association between higher mortality rates and the presence of locally advanced bladder tumors (P = 0.046). Additionally, a reduced sarcopenic index in this study was significantly correlated with lymphovascular invasion. In this study, no correlation was found between perioperative complications and sarcopenic index.
Conclusion: To conclude, a significant association was observed between a reduction in the sarcopenic index and lymphovascular invasion; however, no connection was identified between mortality rates and postoperative complications following RC.

Abstract
Background: Diabetic retinopathy is one of the main causes of blindness in the world and one of the causes of disability in diabetic patients. However, no study has been conducted in Iran to Comparison of Quality of Life between Diabetic Patients With and Without Retinopathy.
Methods: This descriptive-analytical study was conducted on 183 diabetic patients referred to the Jahrom Honari Clinic from October to February 2023. The patients were divided into two groups: diabetic patients without retinopathy complications and diabetic patients with retinopathy complications. The data collection tool included two demographic information questionnaires and a quality of life questionnaire (DQOL-BCI). The data of the two groups and subgroups were compared and analyzed using SPSS version 21 software and descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistical tests (chi-square, t-test, ANOVA, Pearson correlation coefficient) at a significance level of P<0.05.
Results: The majority of diabetic patients participating in the study in the group with retinopathy (70.3%) and the group without retinopathy (75%) were male. The groups of Diabetic Patients With and Without Retinopathy did not differ significantly from each other in terms of demographic variables and were similar. There was a significant difference between Diabetic Patients With and Without Retinopathy in terms of average quality of life (P>0.001). The mean quality of life in the group of diabetic patients with retinopathy (41.19±7.97) was higher than that of the group of diabetic patients without retinopathy (37.22±7.37). There was no significant difference between the mean quality of life and demographic variables in diabetic patients without retinopathy and diabetic patients with retinopathy (P<0.001).
Conclusion: That patients with retinopathy had a higher quality of life than the group without retinopathy. These results were obtained while none of the demographic variables such as age, gender, marital status, and education level had a significant relationship with the quality of life of these patients.

Abstract
Background: Breast cancer is the most common cancer diagnosed in women. Epidemiological studies have led to the hypothesis that vitamin D may reduce the risk of breast cancer. This study aimed to investigate the association between vitamin D deficiency and breast cancer.
Methods: This case-control study was conducted on 59 patients referred to Khatam Al-Anbia Comprehensive Cancer Clinic in Jahrom city between May 2021 and March 2022. Thirty patients with pathologically confirmed ductal or lobular breast cancer in situ or invasive in one or both breasts, with no previous history of the disease and within two months of their breast cancer diagnosis, were considered as the case group. Thirty women without breast cancer who had been referred for breast screening examination were considered as the control group. Both groups were matched for demographic characteristics and age. The data collection tools in this study included demographic information and clinical history of the patients and serum vitamin D levels. Data analysis was performed using SPSS software, version 21 (IBM SPSS, Armonk, NY, USA) and descriptive statistics (mean, percentage, and standard deviation) and inferential statistical tests (logistic regression, Kolmogorov-Smirnov). The significance level was considered to be P<0.05.
Results: The mean age of the patients participating in the case group was 52.17±10.6 and in the control group was 51.24±9.7. There was no statistically significant difference in age (P=0.654). There was also no significant difference between the two groups in terms of body mass index and different body index classifications, menopause age, and age of onset of menstruation. The number of months of breastfeeding in the control group was significantly higher than the case group (P=0.001). The results of logistic regression showed that, on the other hand, there was no significant relationship between the type of pathology of the disease and serum vitamin D levels.
Conclusion: The results of the present study showed that vitamin D deficiency can be a poor prognostic factor in the course of breast cancer.

Abstract
Background: Insects and arthropods, along with their products, have been used as medicinal sources since ancient times, that is called entomotherapy. Cancer is one of the major problems in medical science, for which a drug has not yet been discovered to control it quickly and accurately. Arthropods have been medicinal sources since ancient times and they especially Insects have a high potential for insect therapy because of the biodiversity. This research investigates the effect of insect body extracts and arthropods in inhibiting the growth of cancer cells or tumours, specifically on the breast cancer cell line, MCF7002E
Methods: The basic and applied study was conducted in Isfahan from 2018 to 2023. In this research, six species of insects, namely Gryllotalpa sp., Polyrhachis sp., Dolichovespula sp., Apis mellifera, Periplaneta americana, Drosophila melanogaster, and one species of Chilopoda, Scolopendra sp., were used. The samples were washed with distilled water and 70% alcohol, then frozen and powdered and prepared in 1% DMSO at eight concentrations of 62.5, 125, 250, 500, 1000, 2000, 4000, 8000 μg/ml and were evaluated for the control of two lines of breast cancer cells MCF-7 by the MTT test was performed to check the effect of doses. The affected doses of insects and centipedes were performed in 6 replicates and three times to MCF-7 cells. IC50 and LD50 were calculated by Prism version six software to check the effect of concentrations determine the effective dose and choose the best extract to control the growth of MCF-7 breast cancer cells.
Results: Scolopendra sp., Drosophila melanogaster, Periplaneta americana, Polyrhachis sp., Apis mellifera, and Gryllotalpa sp. are the most effective species, respectively, in inducing apoptosis and cell death in MCF-7 cancer cell line. Dolichovespula sp. had the least effect. Scolopendra sp. at a concentration of 500 μg/litre induced cell death in more than 50% of MCF-7 cancer cells.
Conclusion: The results of the application of seven different genera of arthropods and insects showed that these genera have excellent therapeutic potential, particularly in the treatment of MCF-7 cancer cells.

Abstract
Background: Pulmonary embolism (PE) occurs when a blood clot blocks a pulmonary artery or its branches. Complications after a hysterectomy can include bleeding, infection, thrombosis, damage to surrounding structures and bowel or bladder problems. This study reports a case of acute pulmonary embolism after hysterectomy surgery.
Case Presenetation: A 52-year-old woman who was a candidate for Total Abdominal Hysterectomy (TAH)+Bilateral Salpingo-Oophorectomy (BSO) due to vaginal bleeding for 3 weeks. During the surgery, the patient's hemodynamics were normal. The surgery lasted about one and a half hours. The patient's bleeding and urine output were normal. At the end of the surgery, the patient was released from muscle relaxation with neostigmine and atropine. The patient woke up and had stable hemodynamics during recovery and was transferred to the women's ward. The next day, the patient started walking in the ward when he suddenly had syncope. The cardiopulmonary resuscitation team immediately arrived at the patient's bedside. Due to the patient's poor breathing, the patient was quickly intubated and resuscitation with cardiac massage and appropriate medications was initiated. A cardiologist and radiologist were consulted urgently and they arrived at the patient's bedside. During cardiopulmonary resuscitation, echocardiography showed a clot in the proximal right and left pulmonary arteries, and an appropriate dose of Reteplase was administered with a diagnosis of extensive pulmonary embolism. Unfortunately, despite the medical team's efforts, the patient died.
Conclusion: Based on the results of the present study, patients who undergo hysterectomy with a history of previous bleeding are at risk of acute pulmonary embolism; therefore, these patients should be closely monitored after surgery and receive appropriate medications after surgery to prevent pulmonary embolism as ordered by the Physians.

Abstract
Background: Shoulder labral repair surgery is associated with significant postoperative pain and restricted mobility. Inadequate pain management may lead to delayed rehabilitation, increased risk of chronic pain development, and higher opioid consumption. This study aimed to compare postoperative pain intensity during the first two weeks following shoulder labral repair between patients receiving interscalene block alone versus those receiving interscalene block combined with intravenous morphine.
Methods: In this randomized, double-blind, parallel-group clinical trial, 120 patients undergoing open rotator cuff repair at Chamran Hospital, Shiraz (June-December 2024) were allocated using balanced block randomization. Group 1 received preoperative interscalene block with 30 mL of 0.5% ropivacaine, while Group 2 received the same block plus intravenous morphine (1% mg/kg). Data analysis was performed using descriptive statistics such as mean and percentage and appropriate statistical tests such as Repeated measurement and Anova using SPSS software, version 21 (SPSS Inc., Chicago, IL, USA). The significance level was considered to be (P<0.05).
Results: Demographic characteristics (age, sex, weight, ASA class) showed no significant intergroup differences (p>0.05). Pain scores were significantly lower at all time points in the combination therapy group compared to the block-only group (p<0.05).
Conclusion: The results of the present study showed that the combination of interscalene block with morphine was significantly more effective in reducing pain after rotator cuff surgery than interscalene block alone. This finding suggests that the use of morphine as an additional analgesic can enhance the analgesic effects of interscalene block and provide better pain relief. The combination of these two methods may cause a positive interaction in pain relief and reduce the need for other medications, which consequently prevents the side effects caused by additional analgesic drugs, and patients who receive the combination of these two treatment methods experience greater comfort and better functional improvement. However, it is recommended that further studies focusing on the precise dosage and timing of drug combinations be conducted to obtain more precise results regarding the optimization of pain management after rotator cuff surgery. Also, examining the long-term effects of this treatment method could help to better understand its advantages and disadvantages.

Abstract
Background: Vitamin D deficiency is associated with various complications, including preterm birth, low birth weight, and neonatal infections. This study aimed to measure the level of vitamin D in the umbilical cord blood of full-term and premature babies and consider the prevalence of vitamin D deficiency in pregnant women.
Methods: In this case-control study, maternal vitamin D levels and umbilical cord blood vitamin D levels were estimated in March 2023 at Imam Khomeini Hospital in Ahvaz. The information obtained from questionnaires and laboratory measurements was statistically analyzed. Two groups of term or preterm infants delivered vaginally were enrolled in this study. As part of routine delivery room protocols, 2 mL of umbilical cord blood was collected from each neonate in a non-heparinized tube. The results were determined, and the prevalence of vitamin D deficiency was determined. The samples were categorized into three groups based on vitamin D serum levels: less than 20 ng/ml (severe deficiency), 20-29 ng/ml (moderate deficiency), and higher than 30 ng/ml (normal group).
Results: In this study, 39 term infants (55.7%) and 31 preterm infants (44.3%) participated. The mean umbilical cord blood vitamin D levels were 44.15 ± 24.33 ng/mL in term infants and 30.98 ± 17.05 ng/mL in preterm infants. Similarly, maternal vitamin D levels averaged 17.09 ± 7.87 ng/mL for term pregnancies and 18.76 ± 6.6 ng/mL for preterm pregnancies. Preterm babies had higher odds of underlying diseases (OR: 2.31, 95% CI: 0.51-10.53). Multivitamin consumption was more prevalent among mothers of premature babies (71%). No significant differences in vitamin D levels were found between term and preterm babies or their mothers (P > 0.05).
Conclusion: This study highlights the importance of multivitamin consumption among pregnant women, particularly those at risk of preterm delivery. The increased likelihood of underlying conditions and delayed recovery of vitamin D levels in preterm infants underscores the need for targeted interventions. Moreover, healthcare providers should emphasize vitamin D supplementation and monitoring.

Abstract
Background: Changes in the heart during pregnancy, especially changes in the left side of the heart, have been evaluated in various studies. However, alterations in the right ventricle have not been well studied. Thus, the present study aimed to investigate the changes in echocardiographic indices of the right ventricle in the second trimester of pregnancy.
Methods: In this cross-sectional study, 30 pregnant women, as case group, in their second trimester who were referred to the perinatology clinic of Imam Hossein Hospital, Tehran, were examined by trans-thoracic echocardiography From April 4, 2023, to April 10, 2024. The results of the control group were compared with 30 age-matched non-pregnant and healthy women, as the control group. Exclusion criteria included multiple gestation, maternal age > 40, underlying cardiovascular disease, and significant obstetric or fetal complications. Hemodynamics and demographic data including age, height, weight, and body mass index were recorded and compared. Also, the anatomical and functional indices of the right ventricle were evaluated and compared.
Results: 60 participants were enrolled in this study. The two investigated groups were similar in terms of age, but the weight, height, and BMI were significantly different in the two groups; Such that weight and body mass index were significantly higher in pregnant women and height in non-pregnant women (p<0.05). Comparison of echocardiographic indices showed that tricuspid regurgitation gradient (TRG) and fractional area change (FAC) were significantly different in the two groups (in pregnant women, TRG index was higher and FAC index was lower (p<0.05)). Right atrium area, RV length, base of RV, mid of RV, and Tricuspid annular plane systolic excursion showed no significant differences between case and control group.
Conclusion: FAC and TRG indices were significantly different between pregnant women and the control group. Paying attention to the changes in the normal values of these variables in pregnant women can be useful in improving the diagnosis of disorders and preventing the occurrence of cardiac events during pregnancy.

Abstract
Background: Gliomas are the most common primary brain tumors in adults, with low-grade gliomas making up 15% of cases. These slow-growing tumors often occur in young adults. Radiotherapy is one of the treatment options. New radiotherapy techniques like IMRT may reduce complications by sparing normal tissue. The study aims to determine which tumors benefit most from IMRT based on tumor location and size.
Methods: Patients diagnosed with low-grade glioma who were referred for treatment at the Cancer Institute of Imam Khomeini Hospital between September 2017 and September 2020 were included in this study. All patients underwent CT simulation with a thermoplastic mask for immobilization. A diagnostic MRI (performed within two weeks prior) was fused with the planning CT to define the target volume (GTV/CTV), with contours verified by a neuroradiologist. A doctor outlines the treatment volume and critical organs for both 3D and IMRT techniques. Radiotherapy physics experts design treatment plans using both techniques, which are then approved by a radiation oncologist. The treatment volume coverage and doses to critical organs are compared between the two techniques.
Results: Among 25 patients, 14 patients (56%) with single-lobe involvement, 7 (28%) with two lobes, and 4 (16%) with multifocal disease. Right-side brain involvement was seen in 32%, with the frontal lobe most affected. IMRT significantly reduced the mean and maximum cochlear dose on the treatment side in all patients. It also lowered the mean chiasma dose in those with both lobes involved and reduced cochlear dose on the opposite side in frontal lobe cases. No significant difference was found between the techniques for patients with multiple lobe involvement.
Conclusion: According to our study on 25 patients with low-grade glioma, it was shown that there is no clear difference between the two techniques. Given the young age and long survival of LGG patients, IMRT may be preferred when hearing preservation is a priority. Further studies with larger cohorts are needed to confirm these findings.

Abstract
Background: Chronic heart failure (CHF) is a leading cause of cardiovascular mortality and hospitalization. Heart failure (HF) imposes both direct costs to healthcare systems and indirect costs to society through complications, unpaid care costs, premature mortality, and loss of productivity. The aim of the present study was to investigate the quality of care, laboratory and clinical indicators affecting mortality in heart failure patients.
Methods: In a descriptive study conducted in the summer of 1402, data were collected by extracting the list of patients who died with a diagnosis of heart failure from the hospital's information management system, based on random sampling, and recorded in a checklist. The number of patients selected was from a study of factors affecting mortality in heart failure patients at Shahid Mustafa Khomeini Hospital.
Results: 25.8% of patients had bilateral rales on pulmonary auscultation, and 88.7% of them reported shortness of breath, 58.1% edema, and 22.6% chest pain. LVEF of most patients was 10-25. With a decrease in systolic blood pressure and an increase in diastolic and HR, the probability of mortality increased significantly (1.058, 0.932, and 0.983) times, respectively. With a decrease in oxygen level, the probability of mortality increased significantly by 0.983 times. The mean ALT and AST increased significantly and the mean HCT also decreased significantly. With each unit increase in ALT and AST and each unit decrease in Hct, the probability of mortality increased (1.008, 0.985 and 1.283) times, respectively. With the decrease in Hb and FBS and the increase in Cr and BUN, the probability of mortality increased by 0.314, 1.013, 1.884 and 0.969 times, respectively. However, no significant relationship was observed between mortality and the factors Hb, FBS, Cr and BUN with patient mortality.
Conclusion: Dyspnea and edema were common in patients, and bilateral rales and chest pain were observed in less than half of the patients. A decrease in systolic blood pressure and an increase in diastolic and HR significantly increased the probability of mortality. A decrease in oxygen levels also significantly increased mortality in patients.

Abstract

Background: Varicocele, defined as an abnormal enlargement and tortuosity of the veins in the pampiniform plexus, is the most common cause of correctable male infertility that might increase chance of fertility even in presence of further male factor infertility causes. While it is well known to be reason of fertility in male and is easy to treat, here we present a case with 20 years of infertility due to missed opportunity of varicocelectomy.
Case Presentation: A 39-year-old male patient with a family history of infertility for about 20 years was referred for azoospermia and stated that after two testicular biopsies and failure to obtain sperm in one of the equipped infertility treatment centers, he was recommended to receive a donated embryo, but he wanted to have his biological child genetically. In the history taken, he had a history of mild left varicocele and no other clinical problems, and mild bilateral varicocele was evident on examination. Karyotype and Y chromosome examination were normal, and hormonal tests and gonadotropin and testosterone levels were within normal limits. Semen volume was 1 ml in two tests one month apart, and semen was alkaline. The patient underwent microscopic bilateral varicocelectomy with an inguinal incision. The patient underwent fluoroscopy, vasography, which showed distal dilatation of both Vas deferens. Diluted methylene blue solution was also injected into the vas deferens and Folley was fixed. But the urine color did not turn blue, so the patient's position was changed to lithotomy and the patient underwent resection of the ejaculatory duct via the urethra, that is the Verumontanum was resected with a cautery-cutting cautery. Three months later, the patient presented with a completely normal semen analysis. The patient was advised to try to conceive at least four months after the operation. Two months later, pregnancy occurred again, and after 9 months, a healthy male fetus was born by cesarean section.
Conclusion: This study demonstrates that varicocele treatment can significantly improve fertility parameters and enhance the chances of successful conception in affected patients. The most important suggestion of this case report is to highlight the importance of timely diagnosis and treatment of varicocele as a correctable cause of male infertility. Unfortunately, our patient suffered from infertility for 20 years due to not undergoing varicocelectomy. Even obstruction treatment may not necessarily be needed in this case, as a sole varicocelectomy might make sperm extraction possible for further in vitro procedures.

Abstract
Background: Hemodynamic instability is a significant perioperative complication that can threaten surgical outcome through various mechanisms: exacerbating intraoperative bleeding, compromising visibility of the surgical field, and elevating immediate and delayed postoperative complication risks. In septorhinoplasty, a procedure with challenging hemodynamic control due to the nasal anatomy's complexity of vessels, these effects are particularly relevant. This study examines the modulation of important hemodynamic parameters (SBP, DBP, MAP, HR, and SpO₂) by intravenous dexmedetomidine while ensuring cardiovascular stability and dose-dependent effects and optimal timing of administration at different phases of surgery. The findings aim to offer evidence-based recommendations for hemodynamic control in rhinoplasty surgery, which can reduce rates of complications and improve recovery profiles.
Methods: A randomized, double-blind clinical trial was conducted involving 50 eligible patients (aged 18-45 years) scheduled for septorhinoplasty at Ostad Motahari Hospital, Jahrom, during May-September 2023. Participants were randomly allocated to either a dexmedetomidine or control group. Collected data encompassed demographic characteristics (age, gender, BMI=Body mass index) and hemodynamic parameters (systolic/diastolic blood pressure, mean arterial pressure, heart rate, and oxygen saturation). The data were analyzed using SPSS software, version 21 (SPSS Inc., Chicago, IL, USA). Descriptive statistics (mean, standard deviation, percentage, count, and frequency) and inferential statistical tests (Mann-Whitney U test and independent t-test) were applied. A significance level of P < 0.05 was considered for all statistical analyses.
Results: The dexmedetomidine group demonstrated statistically significant variations in hemodynamic parameters (SBP, DBP, MAP, HR) from pre-induction through post-recovery phases (p<0.001). Significant between-group differences in blood pressure metrics were observed at all measured intervals following induction (1, 5, 15, 30, 60 minutes) and during recovery periods (p<0.05), with the dexmedetomidine group consistently showing lower values. Comparison between the intervention and control groups revealed no statistically significant differences in heart rate and oxygen saturation (O₂ sat) levels (except during recovery time).
Conclusion: The results of this study indicate that dexmedetomidine administration had a significant effect on reducing systolic blood pressure, diastolic blood pressure, and MAP compared to the control group, with this reduction being evident at all measured time points from post-induction to post-recovery. These findings suggest that dexmedetomidine can be effectively used as a blood pressure-lowering agent during surgery without significantly affecting heart rate or the patient's blood oxygen levels.

Abstract
Background: Coronary artery disease (CAD) is among the most common life-threatening cardiovascular diseases, in which blood supply to the heart muscles is reduced or completely blocked. Coronary artery disease has various treatment options, one of which is PCI (Percutaneous Coronary Intervention) or stent placement via angioplasty. Dabigatran etexilate is the only orally available direct thrombin inhibitor, which is actually a prodrug that is rapidly converted to its active form and absorbed through the gastrointestinal tract. The purpose of this study is to compare mortality in patients with Atrial Fibrillation (AF) with a history of Percutaneous coronary intervention (PCI) treated with a low dose (110 mg). In contrast, it was treated with a high dose (150 mg).
Methods: The present study was a systematic review and meta-analysis on 4 online databases PubMed, Scopus, Web of Science and EMBASE to find articles that the rate of long-term complications related to bleeding or Thrombotic events were performed in AF patients who underwent PCI and were treated with dabigatran. STATA software was used for data analysis.
Results: Nine RCTs or prospective studies with 5694 participants were included. The studies showed that when comparing dabigatran (110 and 150 mg) with warfarin (with/without dual antiplatelet), dabigatran 110 mg was associated with a significant reduction in major bleeding (OR=0.46, 95% CI: 0.24-0.86, P=0.01), while the 150 mg dose was not statistically different (OR=0.12, 95% CI: 0.01-1.32, P=0.08). Also, comparing dabigatran 150 with 110 mg showed a higher risk of bleeding at the higher dose (OR=0.77, 95% CI: 0.64-0.92, P<0.001). On the other hand, dabigatran 110 mg was associated with a significant increase in mortality (OR=1.33, P=0.01) and myocardial infarction (OR=1.61, P=0.01) compared with combination therapy of warfarin and antiplatelet, but the 150 mg dose did not show a statistical difference. Heterogeneity was high in some analyses (I2 up to 99.49%), but funnel plots and Egger's test rejected publication bias.
Conclusion: There seems to be strong evidence that bleeding complications in dabigatran are less than old antiplatelet and anticoagulation drugs, but in terms of efficacy in reducing mortality, although we did not obtain strong evidence for analysis, older drugs are more effective in preventing death from any cause.

Abstract
Background: Spinal anesthesia is a common method for elective cesarean sections; however, complications such as shivering and nausea may affect postoperative recovery quality. Bupivacaine is a standard drug used in this procedure, but its combination with opioids like sufentanil may have beneficial effects in reducing these complications. This study aimed to compare the incidence of shivering and nausea in women undergoing elective cesarean section who received either bupivacaine alone or a bupivacaine-sufentanil combination.
Methods: The present study was a double-blind randomized clinical trial conducted over a 6-month period from April 2021 to October 2021 on 30 patients undergoing elective cesarean section with spinal anesthesia at Motahari Hospital in Jahrom city. Patients were randomly assigned using a random number table into two groups: bupivacaine alone and bupivacaine-sufentanil combination. The frequency of nausea, vomiting, and shivering was recorded at different time points: before spinal anesthesia, after spinal anesthesia, 3 minutes before delivery, immediately after delivery, at 15, 30, and 45 minutes, upon recovery room admission, and upon discharge from recovery. The data analysis was performed using descriptive statistics indicators (frequency, percentage, mean, and standard deviation) and inferential statistical tests (t-test, Mann-Whitney, chi-square and Friedman) using SPSS software version 21. A significance level of p < 0.05 was considered.
Results: In the bupivacaine-sufentanil group, the highest frequency of shivering occurred at 30 minutes post-spinal anesthesia (20%) and upon recovery room admission (26.7%). In the bupivacaine-alone group, the highest frequency was observed upon recovery room admission (33.3%) and at discharge from recovery (26.7%). The highest nausea frequency was 33.3% in the bupivacaine-sufentanil group and 40% in the bupivacaine group at 3 minutes before delivery. However, no statistically significant difference was found between the two groups at different time points.
Conclusion: The present study showed that adding low-dose sufentanil to bupivacaine in spinal anesthesia protocols, while potentially having minor clinical effects on certain complications, did not lead to a significant difference in the incidence of shivering and nausea. Therefore, for more precise clinical decision-making regarding drug combinations in regional anesthesia, further studies with larger sample sizes and different drug dosages are recommended.

Abstract
Background: Spinal anesthesia is an effective method for providing analgesia in surgery and a safe alternative to general analgesia; But despite its benefits, in many cases it is not free of side effects, including unwanted cardiovascular events such as hypotension and bradycardia. Ondansetron effectively reduces the incidence of nausea, vomiting, and bradycardia associated with spinal anesthesia Thus, the present study aimed to assess intravenous ondansetron's efficacy in preventing post-spinal hypotension among patients scheduled for lower extremity orthopedic surgery at Peymanieh Hospital in Jahrom, Iran.
Methods: This randomized double-blind clinical trial included 60 patients undergoing lower limb orthopedic surgery at Peymanieh Hospital, Jahrom, Iran, from March 2021 to February 2022. Patients were randomly allocated into two groups: the intervention group (receiving 8 mg intravenous ondansetron) and the control group (receiving distilled water). Systolic and diastolic blood pressure (SBP, DBP) and heart rate (HR) were measured before pre-spinal anesthesia, after spinal anesthesia and then every two minutes for the first ten minutes and at 15, 30, 45, 60 and 90 minutes after surgery. After spinal anesthesia, the patient was asked about pruritus every 10 minutes. Nausea and vomiting during surgery in case of incidence, recording and nausea after spinal anesthesia, the patient was asked every 10 minutes.
Results: The chi-square test indicated no significant differences between the study groups regarding age and sex distribution(P>0.05). Time before anesthesia, immediately after anesthesia, 10 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, and 90 minutes after anesthesia, significant difference between ondansetron and placebo groups from There was no mean SBP and DBP and HR (P <0.05). No significant difference between ondansetron and placebo groups in the incidence of pruritus and nausea and vomiting at different times (p <0.05).
Conclusion: Dose of 8 mg of ondansetron in lower limb orthopedic surgery has no significant effect on hemodynamic symptoms as well as the prevention of postoperative nausea, vomiting and pruritus in these patients. Therefore, to achieve more results regarding the transient effect of this drug, it can be compared with other drugs in the class of HT3-5 receptor antagonists.

Abstract
Background: Although abdominoplasty is cosmetically effective in patients with obesity or a history of significant weight loss, it can lead to serious complications. This case report highlights the role of elevated intra-abdominal pressure and delayed diagnosis of Abdominal compartment syndrome (ACS) in the development of multiorgan failure and patient mortality.
Case Presentation: A 49-year-old female patient with a history of appendectomy and hysterectomy in the past years was admitted to the hospital for cosmetic abdominoplasty. She had a history of hypothyroidism and was taking levothyroxine regularly. Occasional tobacco use was also mentioned in the patient's history. During the operation, in addition to abdominoplasty, liposuction and flank surgery were also performed. The patient was initially placed in the supine position and then in the prone position for the last two hours. During recovery, the patient complained of shortness of breath and developed tachycardia. Despite persistently elevated BUN and creatinine, and progressive acidosis, a surgical consultation was performed with suspicion of Abdominal compartment syndrome (ACS), but this diagnosis was rejected by the surgeon. Also, despite clinical suspicion of Abdominal compartment syndrome (ACS) by the anesthesia team, in the early stages, the surgeon responsible for the patient did not have sufficient clinical suspicion of this complication and accordingly, intra-abdominal pressure measurement via bladder catheter was not performed. Since monitoring intra-abdominal pressure via bladder catheter requires a specific technique and coordination between anesthesia, surgery, and critical care teams, and since the possibility of ACS had been ruled out by the surgeon at that time, this procedure was not performed. Ultimately, the patient was transferred to the dialysis unit, but during hemodialysis, he suffered respiratory arrest and, after tracheal intubation, subsequently suffered cardiac arrest. Unfortunately, despite cardiopulmonary resuscitation efforts, the patient died.
Conclusion: Although rare, abdominal compartment syndrome should be considered a critical differential diagnosis in high-risk patients following prolonged surgeries such as abdominoplasty with extensive plication. Monitoring intra-abdominal pressure and early intervention upon symptom onset may prevent fatal outcomes.

Abstract
Background: To improve hemostasis and optimize the healing process, autologous fibrin sealant (FS) has been introduced in selected cases. However, the clinical benefits of FS in sinonasal surgery remain controversial and require further evaluation. This study aimed to investigate the effects of autologous FS on hemostasis, mucosal healing, postoperative clinical outcomes, and recurrence in patients undergoing bilateral FESS, compared with normal saline as the control.
Methods: This randomized clinical trial included 32 patients who underwent bilateral FESS at Ghaem and Imam Reza University Hospitals in Mashhad, Iran, between 2019 and 2021. For each patient, autologous FS was applied to one nasal cavity, while the contralateral cavity received normal saline. Postoperative outcomes including bleeding, crusting, adhesion formation, and infection were assessed at 1 week, 1 month, and 3 months after surgery. In addition, sinonasal symptom burden and endoscopic findings were evaluated using the Sinonasal Outcome Test (SNOT-22) and the Lund-Kennedy endoscopic score, respectively, both recorded preoperatively and three months postoperatively.
Results: Application of autologous FS significantly reduced immediate postoperative bleeding, and no further bleeding events were noted during follow-up. Pain severity was comparable between the two sides. No statistically significant differences were observed in crust formation, adhesion, infection, recurrence, or changes in Lund-Kennedy scores between the FS and control sides (p=0.08, p=0.8, p=0.17, and p=0.14, respectively).
Conclusion: Autologous fibrin sealant reduced early postoperative bleeding without adversely affecting pain control, mucosal healing, or recurrence after FESS. Larger randomized trials with extended follow-up are recommended to determine its definitive clinical value and potential for routine use in surgical practice.

Abstract
Background: In general anesthesia, anesthetic agents are administered by inhalation or intravenously, leading to loss of consciousness, immobility, analgesia, and amnesia. In spinal anesthesia, injection of a local anesthetic into the intrathecal space causes sensory and motor block. The aim of this study was to compare the volume of bleeding during cesarean section under general anesthesia and spinal anesthesia.
Methods: This study is a cross-sectional prospective study. The gauzes used were weighed before the operation and bloody gauzes were weighed after the operation. The difference between the weight of bloody and dry gauzes was recorded as the volume of bleeding. This volume was then added to the volume of blood in the suction chamber and the final bleeding volume was estimated.
Results: 70 patients who were candidates for cesarean section were included in the study. The mean age of the patients included in the study was 24.82±4.98 and their mean weight was 77.11±8.97. The mean hemoglobin in the spinal anesthesia group was 91.12±39. Volume of bleeding during cesarean section by spinal anesthesia was significantly less than general anesthesia (P=0.001). Also, the visual estimation of bleeding in spinal anesthesia was significantly lower than general anesthesia (P<0.001). In this study, there was no significant difference between heart rate, systolic and diastolic pressure before and during surgery, and the first- and fifth-minute Apgar scores between the two groups of general and spinal anesthesia.
Conclusion: We found in this study that the volume of bleeding during cesarean section under spinal anesthesia is less than general anesthesia. It is suggested that in future studies, other methods of estimating bleeding such as postoperative hemoglobin reduction, dilution method, atomic absorption spectroscopy and photometry be used. Also, a comparison should be made between the three groups of general, spinal and epidural anesthesia, and the volume of bleeding in each should be checked and the best anesthesia method should be selected for cesarean section.
