INTRODUCTION
The purpose of this study was to determine patient perceptions of an advanced practice radiation therapist (APRT) prescribing medication for radiation therapy treatment-related side effects. By comprehending patient perceptions, it is important to implement change in order to improve patients' quality of life.
METHODS
A literature review was conducted on advanced practice (AP) roles in Canada and world-wide; the roles searched were: APRT, nurse practitioner and pharmacist. The search focused on evidence demonstrating improvements made to patient care due to the implementation of these roles. Based on this review and input from a team of experts a qualitative semi-structured interview survey was designed, and pilot tested. The survey consisted of five open-ended questions, which were designed to determine patient satisfaction of an APRT prescribing medication over the course of their radiation therapy treatments. Patients undergoing head and neck radiation therapy treatments at a large, academic cancer centre were invited to participate. Six patients who had a head and neck APRT involved in their treatment were interviewed. A comprehensive thematic analysis was then conducted using the transcripts created from these interviews, which was followed by two independent blinded analyses to ensure validity of the results.
DISCUSSION
The thematic analysis produced four salient themes which were: side effect management, care provided by the APRT in comparison to other healthcare workers, patients' access to care, and overall patient satisfaction. Common medications for head and neck radiation therapy treatment related side effects were discussed and these were: Magic Mouthwash, Xylocaine, Nystatin, Benadryl, Advil, Tylenol, Dexamethasone, Tantum, Biotene, Mucaine, Flamazine, Hydrocortisone, Ondansetron, Senokot, and narcotics.
CONCLUSION
This study was valuable to understand patient experiences and provide evidence to change processes in order to improve quality of patient centered care. The study revealed that although patients were happy with the process of prescribing medication, they all agreed that having an advanced practice radiation therapist prescribe would improve care. Patient responses further demonstrated the need for future research in regards to side effect management as a whole by APRTs as well as how role clarification can impact patient perceptions of APRTs.

BACKGROUND
Spinal anesthesia is commonly performed for cesarean section, however, postdural puncture headache (PDPH) is one of its most common adverse effects. Ondansetron is an antiemetic for cancer treatment and analgesia-induced nausea and vomiting. In this study, the authors aim to evaluate the effect of postoperative ondansetron on PDPH.
METHODS
In this randomized controlled clinical trial study, 120 pregnant patients are ASA ll, undergoing elective cesarean section, were randomized into two groups (placebo or study). The patients in the study group, immediately after the birth of a baby and 24 h after the operation, received ondansetron 4 mg IV while the placebo group received a placebo. The severity and incidence of headache, postoperative nausea and vomiting, dizziness, neck and lower back pain, and the use of analgesia was assessed in the two groups.
RESULTS
The significant meaning of the time effect (<0.001) indicated that regardless of the group, for each unit increase in time, the chance of developing a headache increased by 23%, which was statistically significant. Also, the significant meaning of the group effect indicated that regardless of time, patients who did not take indomethacin had ~4.11 times higher chances of developing a headache compared to those who received the medication, which was statistically significant (=0.004).
CONCLUSION
The administration of ondansetron significantly reduces the occurrence of postspinal anesthesia headaches and neck pain. There was no significant difference in headache severity between the two study groups.

BACKGROUND
Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disorder mainly affecting joints, yet the systemic inflammation can influence other organs and tissues. The objective of this study was to unravel the ameliorative capability of Ondansetron (O) or β-sitosterol (BS) against inflammatory reactions and oxidative stress that complicates Extra-articular manifestations (EAM) in liver, kidney, lung, and heart of arthritic and arthritic irradiated rats.
METHODS
This was accomplished by exposing adjuvant-induced arthritis (AIA) rats to successive weekly fractions of total body γ-irradiation (2 Gray (Gy)/fraction once per week for four weeks, up to a total dose of 8 Gy). Arthritic and/or arthritic irradiated rats were either treated with BS (40 mg/kg b.wt. /day, orally) or O (2 mg/kg) was given ip) or were kept untreated as model groups.
RESULTS
Body weight changes, paw circumference, oxidative stress indices, inflammatory response biomarkers, expression of Janus kinase-2 (JAK-2), Signal transducer and activator of transcription 3 (STAT3), high mobility group box1 (HMGB1), and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), as well as pro- and anti-inflammatory mediators in the target organs, besides histopathological examination of ankle joints and extra-articular tissues. Treatment of arthritic and/or arthritic irradiated rats with BS or O powerfully alleviated changes in body weight gain, paw swelling, oxidative stress, inflammatory reactions, and histopathological degenerative alterations in articular and non-articular tissues.
CONCLUSION
The obtained data imply that BS or O improved the articular and EAM by regulating oxidative and inflammatory indices in arthritic and arthritic irradiated rats.

BACKGROUND
Cisplatin is an effective first line therapy for a variety of cancers. Cisplatin is highly emetogenic and resulting volume depletion can contribute to acute kidney injury (AKI). Anti-emetic drugs such as 5-hydroxytryptamine type 3 receptor antagonists (5-HT3RAs) are commonly prescribed to prevent this complication. Preclinical studies suggest first generation 5-HT3RAs may alter the renal clearance and increase cisplatin toxicity. This retrospective study evaluated whether different 5-HT3RAs modify the risk of AKI in patients receiving cisplatin.
METHODS
Patients with cancer who received cisplatin between January 1, 2010 and December 31, 2016 were included. Patients over 18 years old with available data for baseline and post-treatment serum creatinine, cisplatin cumulative dose, and administration of 5-HT3RAs including first generation (ondansetron, granisetron, and ramosetron) and second generation (palonosetron) were analyzed. AKI defined as 1.5x increase in serum creatinine. Fisher's exact and Wilcoxon rank-sum tests were used to assess univariable associations between baseline covariates and AKI, and logistic regression for multivariable associations with AKI.
RESULTS
Of 8703 patients identified with cisplatin exposure, 6889 were included. A total of 3881 (56.3%) patients received at least one 5-HT3RA, including palonosetron (3750, 54.4%), ondansetron (1399, 20.3%) and granisetron (11, 0.2%). AKI developed in 1666 (24.2%) patients following cisplatin. Patients who received any 5-HT3RAs were less likely to experience AKI as compared to patients that did not (22.6% vs 26.2%, p=0.001). Older age, male gender, African ethnicity, and cumulative cisplatin dose were univariately associated with higher risk for AKI (P<0.001). After adjusting for these variables, use of any of these antiemetic drugs was protective for AKI (OR 0.84, 95% CI: 0.75, 0.94; P= 0.003) with no difference detected between type of 5-HT3RA.
CONCLUSION
Nephrotoxicity continues to be a concern following cisplatin therapy. Given its emetogenic nature, use of antiemetic drugs such as 5-HT3RAs can lessen emesis and lower risk of kidney injury. This retrospective analysis supports use of any 5-HT3RAs to lower risk of AKI.

BACKGROUND
Traumatic brain injury (TBI) patients suffer high risks of mortality. Ondansetron has been verified to be effective in improving the prognosis of some kinds of critically ill patients. We design this study to explore whether ondansetron use is associated with lower risks of mortality among TBI patients.
METHODS
TBI patients from the Medical Information Mart for Intensive Care-III were collected. The usage of ondansetron, including intravenous injection and oral tablet, since admission to the Beth Israel Deaconess Medical Center between 2001 and 2012 was identified. Univariate and multivariate logistic regression were performed to analyze the relationship between the ondansetron use and mortality of TBI patients. Propensity score matching (PSM) was utilized to generate balanced cohorts of the non-ondansetron use group and ondansetron use group. Sub-group analysis was performed to verify the association between the ondansetron use and mortality of TBI patients in different TBI severity levels after PSM.
RESULTS
In TBI cohorts before PSM, the usage incidence of ondansetron was 37.2%. The 30-day mortality was significantly lower in the ondansetron group ( < 0.001). The multivariate logistic regression showed that ondansetron was associated with the lower mortality of TBI patients ( = 0.008). In TBI cohorts after PSM, the 30-day mortality of the ondansetron group was lower than that of the non-ondansetron group, although without statistical significance ( = 0.079). Logistic regression indicated ondansetron use was significantly associated with the lower mortality of moderate-to-severe TBI ( < 0.001) but not mild TBI ( = 0.051). In addition, Cox regression also presented that ondansetron use was significantly associated with the lower mortality of moderate-to-severe TBI ( < 0.001) but not mild TBI ( = 0.052).
CONCLUSION
Ondansetron usage is associated with a lower mortality risk of moderate-to-severe TBI but not mild TBI patients. Ondansetron may be a novel adjunctive therapeutic strategy to improve the prognosis of moderate-to-severe TBI patients.

PURPOSE
- Cocaine use disorder (CUD) is a complex disease. Several studies have shown the efficacy of multitarget drugs used to treat CUD. Here we compare the efficacy of mirtazapine (MIR), pindolol (PIN), fluoxetine (FLX), risperidone (RIS), trazodone (TRZ), ziprasidone (ZPR), ondansetron (OND), yohimbine (YOH), or prazosin (PRZ), to reduce long-term cocaine-induced locomotor activity and the expression of cocaine-induced locomotor sensitization in rats.
METHODS
- The study consists of four experiments, which were divided into four experimental phases. Induction (10 days), cocaine withdrawal (30 days), expression (10 days), and post-expression phase (10 days). Male Wistar rats were daily dosed with cocaine (10 mg/kg; i.p.) during the induction and post-expression phases. During drug withdrawal, the MIR, PIN, FLX, RIS, TRZ, ZPR, OND, YOH, or PRZ were administered 30 min before saline. In the expression, the multitarget drugs were administered 30 min before cocaine. After each administration, locomotor activity for each animal was recorded for 30 min.During the agonism phase, in experiment four, 8-OH-DPAT, DOI, CP-809-101, SR-57227A, or clonidine (CLO) was administered 30 min before MIR and 60 min before cocaine. After each administration, locomotor activity for each animal was recorded for 30 min.
RESULTS
-MIR, FLX, RIS, ZPR, OND, or PRZ attenuated the cocaine-induced locomotor activity and cocaine locomotor sensitization. PIN, TRZ, and YOH failed to decrease cocaine locomotor sensitization. At the optimal doses used, PIN, FLX, RIS, TRZ, ZPR, OND, YOH, or PRZ failed to attenuate long-term cocaine locomotor activation. MIR generated a decrease in cocaine-induced locomotor activity of greater magnitude and duration than the other multitarget drugs evaluated.
CONCLUSION
- At the optimal doses of multitarget drugs evaluated, MIR was the multitarget drug that showed the greatest long-term cocaine-induced behavior effects compared to other multitarget drugs.

Randomized Controlled Trial
Dose-Response Study of Phenylephrine for Preventing Spinal-Induced Hypotension During Cesarean Delivery with Combined Spinal-Epidural Anesthesia Under the Effect of Prophylactic Intravenous Ondansetron.
BACKGROUND
Ondansetron reduces the median effective dose (ED50) of prophylactic phenylephrine to prevent spinal-induced hypotension (SIH) during cesarean delivery. However, the exact dose response of phenylephrine in combination with prophylactic ondansetron for preventing SIH is unknown. Therefore, this study aimed to determine the dose-response of phenylephrine to prevent SIH in cesarean delivery when 4 mg of ondansetron was used as a preventive method.
METHODS
A total of 80 parturients were enrolled and divided randomly into four groups (n = 20 in each group) who received either 0.2, 0.3, 0.4, or 0.5 μg/kg/min of prophylactic phenylephrine. Ten minutes before the initiation of spinal induction, 4 mg prophylactic ondansetron was administered. The effective dose of prophylactic phenylephrine was defined as the dose required to prevent hypotension after the period of intrathecal injection and up to neonatal delivery. The ED50 and ED90 of prophylactic phenylephrine and 95% confidence intervals (95% CI) were calculated using probit analysis.
RESULTS
The ED50 and ED90 for prophylactic phenylephrine to prevent SIH were 0.25 (95% CI, 0.15 to 0.30), and 0.45 (95% CI, 0.39 to 0.59) μg/kg/min, respectively. No significant differences were observed in the side effects and neonatal outcomes between the four groups.
CONCLUSION
The administration of 4 mg of prophylactic ondansetron was associated with an ED50 of 0.25 (95% CI, 0.15~0.30) and ED90 of 0.45 (95% CI, 0.39~0.59) μg/kg/min for phenylephrine to prevent SIH.

Clinical Trial
The prophylactic antiemetic therapies in management of differentiated thyroid cancer patients with radioactive iodine therapy: a single-center, non-randomized clinical trial.
OBJECTIVE
The present study was to investigate three different single-drug regimens to show which was more effective to reduce radioactive iodine therapy (RAI) associated nausea and vomiting, and to compare the occurrence of long-term gastrointestinal diseases after RAI therapy.
METHOD
We performed a single-center, non-randomized clinical trial among patients who underwent RAI therapy from March 2016 to July 2022. Enrolled patients were divided into four cohorts based on the date of the treatment. cohort 1, with no preventive antiemetics; cohort 2, received 20 mg of pantoprazole per day for 3 days; cohort 3, received a 10 mg metoclopramide tablet two times daily for 3 days; cohort 4, oral ondansetron, 8 mg, twice daily for 3 days. The primary endpoints were proportion of patients who experience vomiting episodes and nausea during the 7-day hospital period. Secondary end points included Functional Living Index Emesis (FLIE) quality-of life questionnaires and the occurrence of gastrointestinal diseases.
RESULTS
A total of 1755 patients were analyzed, comprised of 1299 (74.0%) women and 456 (26.0%) men, with a median age of 44 years (range 18-78 years). The characteristics of patient were similar within the four groups. 465 (26.4%) patients developed RAI-associated nausea, and 186 (14.4%) patients developed RAI-associated vomiting. The rate of nausea was significantly decreased in the patients who were taking ondansetron when compared with the other cohorts (<0.05), while the rate of vomiting (≥6 episodes) was slightly lower. As secondary endpoint, FLIE measures ondansetron scored highly compared to other cohorts, from baseline (mean score of 110.53 ± 17.54) to day 7 (mean score of 105.56 ± 12.48). In addition, 48 (2.7%) patients were found to be with gastrointestinal diseases at the end of one year follow up. Multiple RAI therapy and higher dose of I-131 per body weight revealed a significantly independent risk factors of developing gastrointestinal disorders.
CONCLUSIONS
In conclusion, the present study demonstrated that short-term ondansetron could be an effective prophylactic agent in controlling RAI-associated nausea and vomiting. Furthermore, the risk of developing gastrointestinal disorders was significantly higher for patients with multiple RAI therapy and higher dose of I-131 per body weight.

Review
Evidence suggests that available antiemetics are equal to intravenous fluid treatment against acute nausea of other causes than motion sickness, pregnancy, anaesthesia, chemo- or radiation therapy. Each antiemetic is associated with adverse effects, which include movement disorders, sedation, and QT prolongation. Intravenous fluid and treatment directed against underlying pathology is recommended as a first-line treatment against nausea in these patients. If an antiemetic is clinically warranted, ondansetron has the most favourable ratio between side effects and price, as argued in this review.
