This study aims to determine the effects of rosmarinic acid which involved the mechanisms to decrease the postoperative peritoneal adhesion formation in rats. Various incisions and removing a 1 × 1 cm piece of peritoneum was used to induce the peritoneal adhesions. Experimental groups were as follows: 1—Sham group. 2—Control group: Peritoneal adhesions were induced and no treatments were performed. 3—Treatment groups: Following inducing peritoneal adhesions, animals received rosmarinic acid with 50 and 70 mg/kg dosage, respectively. Macroscopic examination of adhesions indicated that adhesion bands were reduced in both treatment groups compared to the control group. Moreover, the adhesion score was decreased in both treatment groups on day 14. Inflammation and fibroblast proliferation were both reduced in the treatment groups on day 14. TGF-β1, TNF-α, and VEGF were all evaluated by western blot and immunohistochemistry on days 3 and 14. Treatment groups reduced inflammatory cytokines on days 3 and 14. The treatment group with a 70 mg/kg dosage decreased TGF-β1 and TNF-α levels more than the other treatment group. The administration of rosmarinic acid significantly reduced MDA and increased CAT levels. In conclusion, the rosmarinic acid was effective to reduce the adhesion bands, inflammatory cytokines, angiogenesis, and oxidative stress.

Background: Pain control methods after cesarean section may interfere with infant breast-feeding. The aim of this study was to evaluate the effect of pethidine on breast feeding of infants born via cesarean section with spinal anesthesia. Methods: In this randomized double-blind clinical trial, we evaluated 116 infants born via cesarean section in Gerash Amiralmomenin hospital (Southern Iran) in 2017. The subjects were selected through purposive sampling and randomly by permuted block randomization and assigned to intervention and control groups. The test group received 100 mg of pethidine as intravenous infusion and the control group received only routine cares. Infants’ breast feeding behavior in both groups was recorded within 48 hours of hospitalization, using the standard tool for rapid assessment of infant feeding behavior, which consists of 4 main components of breastfeeding, including readiness to feed, rooting, latching, and sucking with a score range of 0 to 3 for each component evaluated at 1, 6, 12, 24, 36, and 48 hours postnatally. Data were analyzed using independent t tests and chi-square test. Results: The highest score of breast-feeding behavior pertained to sucking reflexes in the control group and the lowest score to breast feeding readiness in the pethidine group. Readiness for feeding in the control group (2.09±0.53) was significantly higher than the pethidine group (1.81±0.61) (95% CI: 0.0552, 0.5092 and P=0.015). Sucking reflex (95% CI: -0.1461, 0.2208 and P=0.687), latching (95% CI: -0.3012, 0.0345 and P=0.118) and rooting reflexes (95% CI: -0.1685, 0.2342 and P=0.747) were almost equal in the control group (2.54±0.49, 2.52±0.38, 2.5±0.48, respectively) and pethidine groups (2.51±0.43, 2.65±0.45, 2.46±0.53, respectively). The total score of feeding behavior in the control group (9.66±1.04) was higher than that of the pethidine group (9.44 ±.69) (95% CI: -0.2032, 0.6412 and P=0.306). There was no significant difference between the infants’ feeding frequency (95% CI: -0.269, 1.930 and P=0.137) and duration of feeding (95% CI: -3.2067, 0.4597 and P=0.14). Conclusion: Evaluation of infants in the first 48 hours after birth showed that those babies whose mothers received pethidine were less willing to start breast-feeding. However, other components of breast-feeding behaviors were similar.

Background: Peripherally inserted central catheters (PICCs) are an effective method for medication and nutrition infusion in preterm neonates. The present study aimed to identify the incidence of the most common complications of PICC implantation and evaluate the risk factors of each complication. Methods: This historical cohort study was conducted on 2500 neonates with birth weights (BWs)≥500 g and gestational age (GA)>24 weeks who had a history of PICC inserted in three NICUs between August 2015 and August 2018. Data were collected by reviewing medical records. Demographic data and indices of catheter placement, duration of catheter placement, and common complications were recorded. Data analysis was done using SPSS-21. Results: The median cubital vein had the most PICC placement (43%). The most common complication was tip malposition (48.2%). The incidence rates (95% CI) of the main complications such as malposition, edema/occlusion, and PICC migration were 0.0356 (0.0337-0.0377), 0.0134 (0.0122-0.0147), and 0.0088 (0.0079-0.0099), respectively. PICC insertion position was the strongest predictor of malposition for the cephalic vein. Besides, the incidence of malformation in the cephalic vein was about six times higher than in the median cubital vein. Independent risk factors for non-technical complications included BW (OR=0.59, 95% CI 0.44-0.79), administration of hyperosmolar medications (OR=3.43, 95% CI 2.62-4.51), position (OR=2.43, 95% CI 1.92- 3.08), and duration of catheter presence (OR=1.02, 95% CI 1.01-1.03) (P<0.001). Conclusion: The most common complication was malposition related to catheter placement in an emergency. Moreover, BW, administration of hyperosmolar medications, and duration of catheter presence were the most critical risk factors for non-technical complications. Therefore, it is recommended to educate the PICC insertion team to reduce tip malposition and replace long-term catheters.

Background: Carpal tunnel syndrome is a common condition that causes pain, sensory and motor symptoms in the hands, especially in the thumb, index, and middle fingers due to the compression of the median nerve in the carpal tunnel. The purpose of this research was to investigate the effect of the shock wave and phonophoresis in the improvement of clinical symptoms and function of patients with mild to moderate carpal tunnel syndrome. Methods: The present research has employed a double-blind randomized clinical trial on 60 patients in Isfahan, Iran. Patients were randomly divided into 3 treatment groups of shock, phonophoresis, and control, and all patients received conservative treatments. Wrist thermoplastic splint, vitamin B1, and celecoxib were prescribed for all patients. The shock group received their intervention in four sessions of shock once a week for 4 weeks. Patients in the phonophoresis group received phonophoresis (pulse 1:4) 15 minutes every other day for 2 weeks. Pain scores were assessed based on the visual analog pain scale, and the Boston questionnaire severity scale was completed for each patient before, 1 and 2 months after the intervention. The used analytic tests included Fisher's exact tests, 1-way analysis of variance, and repeated measures analysis. Results: Shock wave and phonophoresis showed a significant decrease in pain, symptom severity index (p<0.001), and functional status (p<0.001). This reduction was more persistent in the phonophoresis group. Conclusion: The use of noninvasive shock wave and phonophoresis methods were good alternatives in the treatment of carpal tunnel syndrome.
