Abstract
Background: Nausea and vomiting is one of the most important complications in chemotherapy. Serotonin and dopamine are important neurotransmitters in nausea and vomiting. It seems that oxygen therapy and increase oxygen saturation can cause decrease these neurotransmitters. The aim of this study was to investigate the relationship between arterial oxygen saturation (SaO2) of patients and chemotherapy-induced nausea and vomiting. Methods: A descriptive-analytical study was performed in Koosar Hospital in Semnan, Iran, from 19 September 2013 to 25 April. At first, SaO2 of 30 patients in three periods (pre, during and post chemotherapy) were measured. Severity of nausea and vomiting in three days after chemotherapy was measured with an index of nausea, vomiting and retching (Rhodes Index). Also during chemotherapy, anxiety and depression of patients was measured with Hospital Anxiety and Depression Scale (HADS). Results: In this study thirty patients were evaluated. Most of them were women (66%) with mean age of 55.07±11.9 years old. The most common cancer in patients was breast cancer (46.7%). Mean of SaO2 was 92.1%±3.4 that was not significant difference during the chemotherapy. Mean of nausea and vomiting severity in first day of chemotherapy was (3.27±5.5), in second day was (4.5±6.2) and in third day was (7.2±8.7). The Pearson correlation coefficient did not show the relationship between oxygen saturation with severity of nausea and vomiting (P>0.05). Although severity of anxiety of patients was significant relationship with nausea and vomiting in third day (P=0.03). Conclusion: In this study there was no significant relationship between oxygen saturation and severity of nausea and vomiting, but anxiety of patients was related to nausea and vomiting in third day. Chemotherapy-induced nausea and vomiting was more common in third day and it seems that further research is needed for relationship between oxygen saturation and nausea and vomiting in third day of treatment.

Abstract

Background: Migraine is a recurrent disease which its definitive mechanism is still unknown. Thus mitochondrial dysfunction and neurovascular damage are two hypothetical underlying mechanisms for migraine headaches. The effectiveness of some possibly effective compounds such a CoQ10 has been studied. In this study, we evaluated the efficacy of coenzyme Q10 in migraine headache prophylaxis.
Methods: This study was performed as a double-blinded randomized clinical trial on 112 patients with a diagnosis of migraine who were referred to the Neurology Clinic of Imam Reza Hospital in Kermanshah from March to September 2018. Then the patients were randomly divided into two equal groups (control and intervention). Both groups received propranolol 20 mg twice daily (totally 40 mg/d). The intervention group was treated by CoQ10 60 mg once daily, additionally. Finally, the quantitative and qualitative characteristics of migraine headaches such as nausea and vomiting, photophobia, phonophobia, severity, frequency and duration of attacks were evaluated by Student's t-test, Mann-Whitney U test and Wilcoxon tests.
Results: At the end, it was concluded that CoQ10 supplement of 60 mg daily with propranolol 40 mg daily in patients with migraine headaches improves symptoms more than receiving propranolol 40 mg alone. The results also showed that in the intervention group, nausea and vomiting, photophobia and the severity of headache in patients significantly improved compared to the control group (P values of 0.001, 0.114 and 0.001, respectively). However, the symptoms of phonophobia, frequency and duration of headache attack in the intervention group were not significantly different from the control group (P values were 0.062, 0.853 and 0.106, respectively).
Conclusion: In conclusion considering the main goal of this study, consumption of CoQ10 60 mg daily with propranolol 40 mg daily significantly improves symptoms such as nausea and vomiting, photophobia and severe headache compared to propranolol 40 mg daily. In conclusion, CoQ10 is a suitable choice in patients who do not respond adequately to the standard drug regimen.

Abstract
Background: In this study, the effect of intravenous dexamethasone on pain, nausea and vomiting after laparoscopic ovarian surgery was investigated.
Methods: This randomized clinical trial was conducted from June 2019 to March 2019 on patients undergoing laparoscopic ovarian cystectomy in Beheshti Hospital, Isfahan. In this study, 88 patients aged 18 to 45 years were included in the study. Patients were randomly divided into two groups receiving dexamethasone (D) and normal saline (S). Two minutes before induction of anesthesia, the first group received 8 mg (2 ml) of dexamethasone and the second group received normal saline (2 ml). The duration of surgery and stay in recovery, the frequency of pain and nausea and vomiting, the need for analgesic and anti-nausea drugs, and the cardiovascular response during the study were evaluated and recorded.
Results:  No significant difference was seen in terms of demographic characteristics between the two groups (P>0.05). The frequency of pain during recovery (P=0.4) was not significantly different between the two groups, but at 2 hours (P=0.005), 12 hours (P<0.001) and 24 hours after the operation (P=0.005) (P=0) was significantly lower than S group. The frequency of nausea in group D during recovery (P=0.003), 2 hours later (P<0.001), and 12 hours (P=0.002) was significantly lower than group S, but 24 hours after the surgery, there was no significant difference between the two groups (P=0.15). During recovery, there was no vomiting in both groups (P=1), the frequency of vomiting in 2 hours (P=0.003), 12 hours (P<0.002) and 24 hours after the operation (P=0.48) in group D was lower than S. At the time of the study, the dose of diclofenac and metoclopramide received in group D patients was lower than group S. There was no significant difference in cardiovascular response between the two groups during the study (P>0.05).
Conclusion: Dexamethasone with a dose of 8 mg before induction of anesthesia can be effective in reducing pain, nausea and vomiting after laparoscopic ovarian surgery and reducing the need for analgesics and anti-nausea drugs.
