Abstract

Background: One of the disturbing complications of propofol is pain on venous injection. Some investigators had reported that corticosteroids effectively induce and prolong the duration of local anesthetics. The aim of this study was to assess and comparing the efficacy of propofol pretreatment with dexamethasone in prevalence and severity of its pain on injection.

Materials and Methods: In a randomized, double-blinded, placebo-controlled prospective study, 90ASA I and II, 20 to 60 years-old patients scheduled for elective surgery under general anesthesia were enrolled. In all patients, one of the veins of both hands was catheterized with a 20 G catheter. Then randomly, and simultaneously 2 ml dexamethasone (8 mg) was injected to one of them and 2 ml of normal saline was injected to other. After 30 seconds, 2 ml propofol (20 mg) was injected to both hands, at the same time in 30 seconds. Pain intensity was measured using VAS system.

Results: The age mean was 32.87±5.61. Twenty nine patients were male (32.2%). The mean of pain during propofol injection was significantly lower in dexamethasone group than normal saline group (1.61 vs.4.21 respectively, p< 0.05). Also the pain incidence was significantly lower in dexamethasone group compared to normal saline group (20% vs. 57.78% respectively, p> 0.05).

Conclusion: Intravenous administration of 8 mg dexamethasone before propofol IV injection significantly decreases the pain on injection of propofol.

Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Approximately 2-15% of the global population suffers from migraine headaches. Since acupuncture is one of the treatments for this disorder, the aim of the present study was to assess the effectiveness of this modality on patients with migraine.
Methods: In this experimental interventional study, we enrolled 180 patients with migraine headache attacks at a documented frequency of at least 2 attacks during last 6 months. For all patients, the number, duration and intensity of the headaches were recorded before treatment. To treat the patients, the point with maximal pain was first determined and the meridian was distinguished. Then, the related acupoints were found and stimulated by percutaneous electrical acupuncture for several minutes. The procedure was repeated once per week for six weeks. After completion of all treatment sessions, the patients were visited and questioned about the number, duration and the intensity of headaches.
Results: The mean of number of attacks (9.55±8.26 vs. 3.50±6.77, p=0.001), the mean duration of each attack (9.11±6.59 vs. 3.33±3.65, p=0.001) and the intensity of the attacks (1.83±0.38 vs. 0.61±0.78, p=0.001) were significantly lower after treatment.
Conclusion: Application of acupuncture in patients with migraine headaches is associated with a significant decrease in the mean number, duration and intensity of attacks. Thus, this method of treatment is strongly recommended for migraine headache.

Volume 75, Issue 7 (10-2017)
Abstract
Background: It is known that irisin plays a role in regulating energy balance and body weight. Hence, the aim of this study was to evaluate the effects two models of high intensity interval training and moderate intensity continuous training on the irisin serum and peroxisome-proliferator-activated receptor co-activator-1α (PGC-1α) gene expression in skeletal muscle tissue of male rats.
Methods: This experimental study was conducted in Baqiyatallah University of Medical Sciences during the summer months of 2016. In this study, 32 male Wistar rats (mean weight =250±55 g, age: 8 weeks) were randomly and equally were divided in to 4 groups: basic control (CO), control of eight weeks (CO8w), moderate intensity continuous training (MICT) and high intensity interval training (HIIT). CO group rats at baseline were killed and CO8w group was held concurrently with the experimental group but did not participate in any exercise training. HIIT and MIET groups for 8 weeks also did moderate continuous training (15-60 minute at 15-30 m/min) and sever intensity continuous training (4-8 one-minute intense interval of 28-58 m/min, with a 3-7 one-minute slow interval of 28-58 m/min). The enzyme-linked immunosorbent assay (ELISA) method for measuring serum irisin levels and real-time PCR method for the relative expression of mRNA of PGC-1α gene were used. The data were analyzed by one-way analysis of variance (ANOVA) and Tukey's post-hoc test at P<0.05 level. All analyzes were performed using SPSS software, version 21 (SPSS Inc., Chicago, IL, USA).
Results: The results showed that the relative expression of mRNA of PGC-1α gene significantly increased in both exercise groups compared to the control groups (P=0.001). In contrast, in comparison of control groups, neither HIIT nor MICT had no significant effects on serum irisin levels (P=0.20).
Conclusion: The results show that the two methods of exercise training may be the upstream pathway's activation can increase transcription of the PGC-1α gene (a key regulator of energy metabolism and mitochondrial biogenesis) in skeletal muscle, but doesn't make a significant change in the levels of serum irisin.

Volume 77, Issue 2 (5-2019)
Abstract
Background: Intensity-modulated radiotherapy (IMRT) is one of the most usable methods in prostate radiotherapy that is used with different techniques. The aim of this study was to evaluate and compare the dosimetric and radiobiological effects of prostate IMRT techniques regarding to joint volume between the target tissue and organs at risk as a patients anatomical parameter.
Methods: This research was a cross-sectional, analytical, and quantitative study that was carried out from April 2016 to June 2018 at the radiotherapy and oncology center of Shoheday-e-Tajrish Hospital and Medical Physics Department of Tarbiat Modarres University Tehran, Iran. Four various prostate IMRT techniques (9, 7 and 5 fields and automatic) were planned on 63 prostate cancer patients CT scans. Radiobiological effects were calculated using Relative Seriality model for the organs at risk (bladder and rectum) and target tissue. Results of mentioned prostate IMRT techniques were compared based on the patient’s anatomical parameter. 
Results: For the patients with joint volumes ranged from 0 to 15%, statistical differences were not observed among various IMRT techniques. The tumor control probability and complication free tumor control probability values decreased as a function of joint volume. The normal tissue complication probability value increased as a function of joint volume. The 9 and 7 fields IMRT techniques had not any significant differences (P=0.06) in all of the joint volume ranges. In patients with the joint volumes higher than 30%, the 9 and 7 fields techniques showed significantly better radiobiological values in comparison with 5 fields and automatic techniques (P=0.009).
Conclusion: In the patients with lower percentage of joint volume, all the mentioned prostate IMRT techniques showed same radiobiological effects; however, in the patients with higher joint volume percentages (> 30%), the 9 and 7 fields techniques have better results. It is proposed to use the 7 fields technique instead of the 9 fields technique, especially in prostate cancer cases with high uncertainty in patients’ setup.

The impact of high-intensity interval training (HIIT) combined with berberine supplementation on hematological parameters in middle-aged men with pre-diabetes: a randomized controlled trial

Volume 81, Issue 10 (1-2024)
Abstract
Background: Exercise programs can lead to different physiological adaptations, but the effects of low-volume, low-frequency HIIT protocols with varying interval structures have not been thoroughly investigated. This study aimed to explore the impact of HIIT with high compression (HC) and low compression (LC), with or without berberine (BBR) supplementation, on hematological parameters in pre-diabetic men.
Methods: This semi-experimental study was conducted between October and December 2021 at Mazandaran University. Fifty-four overweight/obese men with a mean age of 48.6±6.6 years, a body mass index of 30.7±7.3 kg/m², and a body fat percentage of 34.4±4.3% were randomly and equally divided into one of six groups: HC, LC, HC+BBR, LC+BBR, BBR, and control. The HC group (2:1 work-to-rest ratio) and LC group (1:1 work-to-rest ratio) underwent training programs comprising 2-4 sets of 8 exercises at an intensity of 80-95% of their maximum heart rate twice a week for 8 weeks. Hematological responses to Bruce's incremental exercise test were measured before and after the intervention. Data were analyzed using a two-way ANOVA with Bonferroni's post hoc test, with a significance level set at P<0.05.
Results: Baseline hematological indices showed no significant differences between pre-diabetic and non-diabetic groups (all, P>0.05). Following the 8-week intervention, there were significant decreases in white blood cells (WBCs) in the LC and LC+BBR groups, and in lymphocytes across all intervention groups except BBR (all, P<0.05). Additionally, hemoglobin and hematocrit levels showed significant reductions in the HC and HC+BBR groups (both, P<0.05). However, in response to Bruce's incremental exercise test, a significant decrease in WBCs was observed in the LC and LC+BBR groups, with reductions of 18% and 25%, respectively (both, P<0.05).
Conclusion: The LC protocol, even without berberine supplementation, seems to provide better immunological benefits and result in less hemolysis compared to the HC protocol, as evidenced by reductions in white blood cell counts.

Abstract
Background: Fatty liver disease is the most common cause of chronic liver diseases in the world, which can cause cardiovascular diseases, so this research aims to scrutiny a period of intense intermittent sports activity and growth hormone perfuse on cardiac mitochondrial PGC1α and some indicators of oxidative stress in mice with liver damage.
Methods: The present research was conducted from September 2022 to March 2023 in the specialized physical training laboratory of Ferdowsi University of Mashhad. The statistical population was twenty one adult male Syrian mice with an average weight of twenty three grams. The sports activity protocol was adopted for fifty-six days using the special video recorder for rodents. The intense interval training program was carried out in the form of ten one-minute repetitions and two-minute active rest, so that the total daily training time for each person was thirty minutes.The vaccination protocol includes the daily vaccination of somatropin injected intraperitoneally.
Results: The PGC1α levels were significantly higher in both the HIIT (P=0.02) and H- GH (P=0.03) groups collationed to the witness team. Moreover, the levels of SOD were considerably increased, in both the HIIT (P=0.05) and H-GH (P=0.005) team s compared to the witness team. Moreover, the levels of MDA were considerably decreased, in both the HIIT (P=0.007) and H-GH (P=0.04) teams compared to the witness team. The decrease in insulin resistance was significant only in the HIIT (P=0.05) team compared to the witness team and slightly increased in the H-GH (P=0.36) team but was not considered. The difference between HIIT and H-GH team (P=0.03) was also significant.The proportion of ALT/AST in both HIIT (P=0.02) and H-GH (P=0.03) teams had a significant decrease compared to the witness team. LDL/HDL proportion evidenced considered decrement at just in the HIIT team (P=0.01).
Conclusion: Intense intermittent sports activity was able to produce a more optimal response compared to GH peptide in improving NAFLD-related indices. Injection of this hormone single may have adverse outcomes on some indexes of this abnormality.
