Effect of ginger and P6 acupressure on chemotherapy-induced nausea and vomiting: a randomized controlled study.

OBJECTIVE: To evaluate the effect of ginger with P6 acupressure in preventing and treating chemotherapy-induced nausea and vomiting (CINV) in cancer patients. METHOD: A total of 172 participants were randomly divided into the control, ginger, acupressure, and joint groups, who were hospitalized in the Affiliated Hospital of Xuzhou Medical University from February and September 2022. The baseline characteristics, nausea, vomiting, and retching, benefit finding, functional living index-emesis, treatment satisfaction, and adverse reaction, were used in data collection. RESULTS: No significant difference was found in benefit finding and adverse reactions among the four groups (P > 0.05). Ginger significantly improved delayed CINV and function living index-nausea (P < 0.05) but had no significant effect on acute CINV, retching, and delayed vomiting, functional living index-emesis, and treatment satisfaction (P>0.05). Acute nausea and retching, delayed nausea, vomiting, and retching, functional living index-emesis, and treatment satisfaction were effectively improved in the acupressure and joint groups (P < 0.05). CONCLUSION: Ginger with P6 acupressure may contribute to improving CINV in patients undergoing chemotherapy.

Herbal medicine for the prevention of chemotherapy-induced nausea and vomiting in patients with advanced colorectal cancer: A prospective randomized controlled trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Chinese herbal medicine is increasingly used as complementary therapy to manage nausea and vomiting in different cultures. One such herbal recipe is the Hezhong granules, which contain classical antiemetic formulations, and are commonly used to prevent chemotherapy-induced nausea and vomiting (CINV). Modern pharmacological studies have shown that the key components of Hezhong granules, including Pinellia ternata (Thunb.), Evodia rutaecarpa (Juss.), and Zingiber officinale exhibit significant antiemetic and antitumor properties. Despite this promising evidence, controlling CINV remains a significant challenge in cancer treatment. Moreover, there is a lack of scientifically designed clinical trials to validate the efficacy and safety of classical antiemetic formulas for CINV interventions. AIMS OF THE STUDY: To investigate the efficacy and safety of Hezhong granules in preventing CINV in patients with advanced colorectal cancer (CRC). METHODS: This study was conducted between October 2020 and February 2022 in 12 hospital wards in Southwest China. In this multicenter, randomized controlled trial, we enrolled patients with advanced CRC who received fluorouracil-based chemotherapy. The patients were randomly assigned in a 1:1 ratio to either the Hezhong granule group (receiving a 5-HT3-receptor antagonist, dexamethasone, and Hezhong granules) or the placebo group (receiving a 5-HT3-receptor antagonist, dexamethasone, and placebo) during the first and second courses of chemotherapy. A 5-day diary was provided to all patients. Acute and delayed CINV were defined as CINV occurring within 24 h or between 24 and 120 h after the start of treatment. The primary endpoints were complete response rate (CRR, defined as the proportion of patients without nausea/vomiting) and objective response rate (ORR, defined as the proportion of patients without nausea/vomiting plus mild nausea/vomiting) for both acute and delayed CINV. Secondary endpoints were the daily rates of CINV events and Functional Living Index-Emesis (FLIE). To identify the predictors of CINV, we conducted multivariate ordered logistic regression analysis. This study was registered with the Chinese Clinical Trial, number ChiCTR2100041643. RESULTS: A total of 120 participants were randomly assigned, of whom 112 (56/56) completed two cycles and were included in the full analysis. In the acute phase, there were minor improvements in the Hezhong granule group, but there were no significant differences in the CRRs for nausea and vomiting (mean difference:10.7 %, P = 0.318, 0.324), while the ORRs increased by approximately 17.5 % (mean difference:16.1 %, P = 0.051; 17.9 %, P = 0.037, respectively). In the delayed phase, significant improvements of approximately 20 % were observed in both the CRRs (mean difference:19.6 %, P = 0.053; 21.4 %, P = 0.035) and ORRs (mean difference:17.9 %, P = 0.037, 0.043) for nausea and vomiting. Additionally, the daily rate of CINV events showed a mean difference of 19 % (P < 0.05). According to FLIE scores, approximately 70 % of patients who received Hezhong granules reported an improvement in their quality of life, with CINV symptoms having"no impact on daily life (NIDL)". No serious adverse events were attributed to herbal medicine. CONCLUSIONS: Hezhong granules proved to be both effective and well-tolerated in preventing CINV in patients with advanced CRC, with notable benefits in preventing delayed CINV. These promising results set the stage for subsequent phase III clinical trials and experimental research on Hezhong Granules.

Adherence to antiemetic guidelines in solid cancer patients receiving highly emetogenic chemotherapy in Korea.

BACKGROUND: Highly emetogenic chemotherapy (HEC) is known to induce nausea and vomiting (CINV) in approximately 90% of cancer patients undergoing this regimen unless proper prophylactic antiemetics are administered. This study aimed to analyze the use of a three-drug prophylactic antiemetic regimen during the first cycle of chemotherapy and assess the compliance rate with the National Comprehensive Cancer Network (NCCN) guidelines. METHODS: This retrospective study utilized data from the National Inpatient Sample database from 2016 to 2020 provided by the Health Insurance Review and Assessment Service. The claims data encompassed 10 to 13% of inpatients admitted at least once each year. Patients with solid cancers treated with two HEC regimens, namely anthracycline + cyclophosphamide (AC) and cisplatin-based regimens, were selected as the study population. We evaluated the use of a three-drug prophylactic antiemetic regimen, including a neurokinin-1 receptor antagonist, a 5-hydroxytryptamine-3 receptor antagonist, and dexamethasone and compliance with the NCCN guidelines. Multiple logistic regression was conducted to estimate the influence of variables on guideline adherence. RESULTS: A total of 3119 patients were included in the analysis. The overall compliance rate with the NCCN guidelines for prophylactic antiemetics was 74.3%, with higher rates observed in the AC group (87.9%) and lower rates in the cisplatin group (60.4%). The AC group had a 6.37 times higher likelihood of receiving guideline-adherent antiemetics than the cisplatin group. Further analysis revealed that, compared to 2016, the probability of complying with the guidelines in 2019 and 2020 was 0.72 times and 0.76 times lower, respectively. CONCLUSION: This study showed that a considerable proportion of HEC-treated patients received guideline-adherent antiemetic therapies. However, given the variations in adherence rates between different chemotherapy regimens (AC vs. cisplatin), efforts to improve adherence and optimize antiemetic treatment remain essential for providing the best possible care for patients experiencing CINV.

Discovering different acupoint combinations of manual or electro-acupuncture to treat chemotherapy-induced nausea and vomiting based on the complex networks analysis.

OBJECTIVES: The aim of this research was to find the acupoint combinations of manual and electro-acupuncture to treat chemotherapy-induced nausea and vomiting via the complex networks analysis. METHODS: We conducted searches using PubMed, ScienceDirect, MEDLINE, Ovid, spring, Wiley, EMBASE, the Chinese biomedicine database, VIP information network, and China National Knowledge Infrastructure from the establishment of the databases to the August, 2023. Information about titles, journals, interventions, and main acupoints was extracted using the self-established "acupoint for prevention CINV data base" powered by EpiData. According to the level of literature evidence and sample size, the clinical trials and weights of the outcome indicators including nausea/vomiting efficiency were combined. After identifying articles, literature processing and complex network analysis were conducted. The degree distribution of each node, the probability distribution of node degree, the node clustering coefficient, and the distance matrix are calculated by software. RESULTS: Of the 4001 screened publications, 489 were eligible after careful selection. Our result showed the acupoints ST36 and PC6 were the most common combination acupoints in both electro and manual acupuncture. In terms of efficiency, ST36, PC6, and CV12 are significantly effective acupoints for manual acupuncture, and the PC6 and ST36 are effective acupoint for electro-acupuncture. CONCLUSIONS: We found that the near-far collocation method has been commonly used for different types of acupuncture treatment in CINV. Zhongwan, Shangwan, and Liangmen have been mainly used as local acupoints, while Neiguan, Hegu, Quchi, Zusanli, Gongsun, TaiChong, and Neiguan have been mainly used as distal acupoints. From the effect analysis, acupuncture treatment of nausea manual acupuncture effect is better; acupuncture treatment of vomiting or electro-acupuncture effect is better.

Effect of a Standardized Ginger Root Powder Regimen on Chemotherapy-Induced Nausea and Vomiting: A Multicenter, Double-Blind, Placebo-Controlled Randomized Trial.

BACKGROUND: There is substantial interest in the role of ginger as an adjuvant therapy for chemotherapy-induced nausea and vomiting (CINV). However, available evidence lacks robust methodology. OBJECTIVE: To assess the effect of adjuvant ginger compared with placebo on chemotherapy-induced nausea-related quality of life (QoL) and CINV-related outcomes. DESIGN: A parallel, double-blind, placebo-controlled randomized trial with 1:1 allocation was conducted. PARTICIPANTS/SETTING: One hundred three chemotherapy-naïve adults scheduled to receive moderately to highly emetogenic chemotherapy at two hospitals in Australia were enrolled and analyzed. INTERVENTION: Four standardized ginger capsules (totaling 84 mg/day active gingerols/shogaols), or placebo, were administered commencing the day of chemotherapy and continuing for 5 days for chemotherapy cycles 1 through 3. MAIN OUTCOME MEASURES: The primary outcome was chemotherapy-induced nausea-related QoL. Secondary outcomes were vomiting- and CINV-related QoL; anticipatory, acute, and delayed nausea and vomiting; fatigue; nutritional status; depression and anxiety; health-related QoL; and adverse events. STATISTICAL ANALYSES PERFORMED: Intention-to-treat analysis was performed. Mixed analysis of variance with repeated measures determined differences between groups. The null hypothesis was no difference between groups. After applying a Bonferroni multiple testing correction, evidence against the null hypothesis was considered at P= 0.003. RESULTS: One hundred three participants (ginger: n = 52; placebo: n = 51) were enrolled and analyzed. There was clinically relevant evidence against the null hypothesis, favoring ginger, in change scores for nausea-related QoL (F[df] = 9.34[1,101]; P = 0.003; partial η2 = 0.09), overall CINV-related QoL (F[df] = 12.26[1,101]; P < 0.001; partial η2 = 0.11), delayed nausea severity (F[df] = 9.46[1,101]; P = 0.003; partial η2 = 0.09), and fatigue (F[df] = 10.11[1,101]; P = 0.002; partial η2 = 0.09). There was a clinically meaningful lower incidence of delayed nausea and vomiting in the ginger group at Cycle 2 (53% vs 75%; P = 0.020 and 4% vs 27%; P = 0.001, respectively) and Cycle 3 (49% vs 79%; P = 0.002 and 2% vs 23%; P = 0.001, respectively). There was a clinically meaningful lower incidence of malnutrition in the ginger group at Cycle 3 (18% vs. 41%; P = 0.032) and in change scores for Patient-Generated Subjective Global Assessment (F[df)] = 4.32[1,100]; P = 0.040; partial η2 = 0.04). Change scores between groups favored ginger for vomiting-related QoL and number of vomiting episodes; however, findings were not clinically meaningful. There was no effect of ginger on anticipatory or acute CINV, health-related QoL, anxiety, or depression. No serious adverse events were reported. CONCLUSIONS: Ginger supplementation was a safe adjuvant to antiemetic medications for CINV that enhanced QoL during chemotherapy treatment. Future trials are needed to examine dose-dependent responses to verify optimal dosing regimens.

Effects of PC6 acupressure on acute and delayed nausea and vomiting induced by chemotherapy in patients with malignant neoplasm: a meta-analysis.

OBJECTIVE: Evaluating the intervention effect of PC6 acupressure on chemotherapy-induced acute, delayed nausea, and vomiting in malignant tumor patients. METHOD: Eleven databases had been retrieved from January 2010 through January 2022. The published meta-analysis literature was hand-searched, and the language was limited to English and Chinese. The protocol of this meta-analysis was registered with PROSPERO (registration number: CRD42022323693). Two reviewers independently selected relevant eligible articles, extracted data, and evaluated the risk of bias. Meta-analysis was statistically analyzed using software RevMan 5.3. RESULT: Ten randomized controlled trials with 975 patients were included. Only two studies were assessed as high quality; eight studies were evaluated as moderate. Meta-analysis showed that compared with the control group, PC6 acupressure reduced the occurrence number of acute (SMD = -0.39,95CI (-0.73, -0.05) P = 0.02), delayed (SMD = -0.51, 95% CI (-0.96, -0.05) P = 0.03) nausea and acute (SMD = -0.42,95% CI (-0.79, -0.06) P = 0.02), delayed (SMD = -0.37, 95% CI (-0.77, 0.03) P = 0.07) vomiting; it reduced the severity of acute (SMD = -0.34, 95% CI (-0.57, -0.11) P = 0.004), delayed (SMD = -0.79, 95% CI (-1.33, -0.25) P = 0.004) nausea and acute (SMD = -0.51, 95% CI (-0.79, -0.23) P = 0.0004), delayed (SMD = -0.50, 95% CI (-0.84, -0.17) P = 0.003) vomiting, while it did not reduced the experience time on acute and delayed CINV. CONCLUSION: The meta-analysis shows the effectiveness of PC6 acupressure in preventing and treating nausea and vomiting. Large, high-quality, well-designed randomized controlled trials are needed in the future to determine the efficacy of PC6 acupressure on chemotherapy-induced nausea and vomiting.

Ginger potency on the prevention and treatment of breast cancer.

BACKGROUND: Cancer is a type of disease caused by the uncontrolled growth of abnormal cells that can destroy body tissues. The use of traditional medicine naturally uses plants from ginger with the maceration method. The ginger plant is a herbaceous flowering plant with the Zingiberaceacea group. METHODS: This study uses the literature review method by reviewing 50 articles from journals and databases. RESULTS: A review of several articles, namely ginger has bioactive components such as gingerol. Ginger is used as a treatment in complementary therapies using plants. Ginger is a strategy with many benefits and functions as a nutritional complement to the body. This benefit has shown the effect of anti-inflammatory, antioxidant, and anticancer against nausea and vomiting due to chemotherapy in breast cancer. CONCLUSION: Anticancer in ginger is shown by polyphenols associated with anti-metastatic, anti-proliferative, antiangiogenic, anti-inflammatory, cell cycle arrest, apoptosis, and autophagy. Therefore, consuming ginger regularly affects natural herbal therapy with the prevention and treatment of breast cancer and serves as a prevention against the effects of chemotherapy.

A pilot randomized control trial of topical capsaicin as adjunctive therapy for nausea and vomiting of pregnancy.

BACKGROUND: Nausea and vomiting is one of the most common complications of pregnancy, affecting 50% to 80% of pregnant persons. Moreover, despite its prevalence, it remains a challenging condition to treat. Treatment often involves oral and intravenous medications with potential side effects, particularly when taken in combination. Capsaicin cream is proven to decrease nausea and vomiting in cyclic vomiting syndrome; however, its use has not been well studied among pregnant patients. OBJECTIVE: This study aimed to test the feasibility of the off-label use of capsaicin for the treatment of nausea and vomiting in pregnancy. STUDY DESIGN: This was a double-blinded randomized controlled trial of pregnant individuals in their first trimester of pregnancy seeking care at a tertiary care hospital for nausea and vomiting. Consenting participants were randomized to abdominal application of topical capsaicin vs placebo. All participants received intravenous hydration and metoclopramide. The primary outcome, total treatment time, was recorded for all participants. In addition, symptom severity was assessed every 30 minutes using a visual analog scale. Data were analyzed using the Wilcoxon rank-sum test for continuous variables and the Fisher exact test for binary variables. RESULTS: Of the 38 eligible individuals approached, 30 were randomized. There was a trend toward decreased mean treatment time in the capsaicin group compared with the placebo group (79.9 vs 97.3 minutes; P=.1). There was no significant difference in visual analog scale scores at any time point between groups. Furthermore, capsaicin was well tolerated, with only 1 individual requesting the medication be removed. CONCLUSION: This study demonstrated that capsaicin is an acceptable treatment of nausea and vomiting in pregnancy and additional explorations of its use as treatment are feasible. A larger randomized controlled trial is needed to determine the efficacy of capsaicin in this population.

Acupuncture for the prevention of chemotherapy-induced nausea and vomiting in cancer patients: A systematic review and meta-analysis.

PURPOSE: To assess the effectiveness and safety of acupuncture for the prevention of chemotherapy-induced nausea and vomiting (CINV), with a specific intention on exploring sources of between-study variation in treatment effects. METHODS: MEDLINE, EMBASE, Cochrane CENTRAL, CINAHL, Chinese Biomedical Literature Database, VIP Chinese Science and Technology Periodicals Database, China National Knowledge Infrastructure, and Wanfang were searched to identify randomized controlled trials (RCTs) that compared acupuncture to sham acupuncture or usual care (UC). The main outcome is complete control (no vomiting episodes and/or no more than mild nausea) of CINV. GRADE approach was used to rate the certainty of evidence. RESULTS: Thirty-eight RCTs with a total of 2503 patients were evaluated. Acupuncture in addition to UC may increase the complete control of acute vomiting (RR, 1.13; 95% CI, 1.02 to 1.25; 10 studies) and delayed vomiting (RR, 1.47; 95% CI, 1.07 to 2.00; 10 studies) when compared with UC only. No effects were found for all other review outcomes. The certainty of evidence was generally low or very low. None of the predefined moderators changed the overall findings, but in an exploratory moderator analysis we found that an adequate reporting of planned rescue antiemetics might decrease the effect size of complete control of acute vomiting (p = 0.035). CONCLUSION: Acupuncture in addition to usual care may increase the complete control of chemotherapy-induced acute vomiting and delayed vomiting but the certainty of evidence was very low. Well-designed RCTs with larger sample sizes, standardized treatment regimens, and core outcome measures are needed.

Huo Xiang Zheng Qi Oral Liquid Combined with 5-HT3 Receptor Antagonists and Dexamethasone Can Prevent Chemotherapy-Induced Nausea and Vomiting for Patients Receiving Multiday Cisplatin-Based Regimen: A Multicenter Trial.

Background: Chemotherapy-induced nausea and vomiting (CINV) is one of the most distressing side effects associated with deterioration in the quality of life. This study aimed to assess the clinical value of Huoxiang Zhengqi (HXZQ) oral liquid, a Chinese patent medicine, in combination with 5-HT3 receptor antagonists (RAs) and dexamethasone, in preventing CINV in patients receiving multiday cisplatin-based chemotherapy. Methods: In this multicenter, exploratory randomized clinical trial, the authors compared the efficacy of HXZQ oral liquid against a control group receiving a placebo, in combination with 5-HT3 RAs and dexamethasone, in preventing CINV in chemotherapy-naive patients receiving a multiday cisplatin-based regimen between January 2021 and September 2021. The primary endpoint was the complete response (CR) rate. The secondary endpoints included days with no CINV, the incidence of CINV, and life function. Results: Sixty patients were randomized into two groups and included in the study. The CR rate was significantly improved by HXZQ oral liquid in acute CINV (63.33% vs. 33.33%, p = 0.020) and CINV beyond the risk phase (96.67% vs. 46.67%, p = 0.000). The number of days with no CINV was significantly more in the HXZQ group compared with the control group in the overall phase (18.10 ± 3.64 vs. 12.13 ± 7.63, p = 0.002). Significantly higher Functional Living Index-Emesis total and domain scores were observed in the HXZQ group. Conclusions: HXZQ oral liquid combined with 5-HT3 RAs and dexamethasone is a feasible and safe approach to prevent CINV in patients receiving multiday cisplatin-based chemotherapy who cannot use neurokinin 1 RAs. Clinical Trial Registration: ChiCTR2000040123.

Mitigation of Chemotherapy-Induced Nausea Using Adjunct Music Listening: A Pilot Study.

The persistence of chemotherapy-induced nausea (CIN) underscores the need to consider nonpharmacologic treatments such as music listening as adjunct interventions. This pilot study investigated the feasibility and overall effects of a 30-minute adjunct music listening intervention in 12 patients experiencing CIN. Music listening was started at the time participants took their as-needed antiemetic medication, and it was repeated as needed during the 5 days after chemotherapy. Data for 66 music listening engagements were collected. A significant reduction of nausea severity (t = 10.97, p < .001) and distress (t = 9.86, p < .001) was noted overall, as well as significant reductions when examining the acute and delayed phases of nausea individually. Qualitative data on study feasibility demonstrated the intervention was well received by participants and held minimal operational difficulty. Investigator feasibility data suggested good understanding of data collection tools. Improvements to the study design have been collected and will form the basis of the future randomized controlled trial.

Comparing the Effect of Incentive Spirometry and Deep Breathing Exercises on the Level of Shoulder Pain and Nausea Following Laparoscopic Cholecystectomy Surgery: A Clinical Trial Study.

Cholecystitis treated by laparoscopy results in patients experiencing shoulder pain and nausea. Thus, the aim of the present study was to compare the effect of incentive spirometry and deep breathing exercises on the level of shoulder pain and nausea following laparoscopy. In this clinical trial, 105 patients were enrolled into three groups: use of incentive spirometry, deep breathing exercises, and control. Data were collected using a checklist and a visual analog scale and analyzed through the χ2, the Kruskal-Wallis, the Friedman, and the paired t test by SPSS Version 25. In the deep breathing exercise, incentive spirometry, and control groups, mean pain scores immediately after surgery but within 24 hours following the intervention were 3.8, 2.6, and 4.4, respectively. The mean score of severity of nausea for patients in the deep breathing exercise and incentive spirometry groups showed a significant difference immediately after the procedure, as well as at 12 and 24 hours post-intervention. Breathing exercises and incentive spirometry can be effective in reducing pain and nausea in patients undergoing cholecystectomy through laparoscopy. Because of the effectiveness of the two methods, nurses can use incentive spirometery and deep breathing exercises to diminish patients' pain post-cholecystectomy.

Integrative and complementary practices to control nausea and vomiting in pregnant women: a systematic review.

OBJECTIVE: to synthesize the evidence available in the literature on the effects of integrative and complementary practices in nausea and vomiting treatment in pregnant women. METHOD: a systematic review, reported according to PRISMA and registered in PROSPERO. The search for studies was carried out in 11 databases. To assess risk of bias in randomized clinical trials, the Cochrane Collaboration Risk of Bias Tool (RoB 2) was used. RESULTS: the final sample consisted of 31 articles, divided into three categories: aromatherapy, phytotherapy and acupuncture. It was observed that aromatherapy with lemon essential oil, ginger capsules, pericardial 6 point acupressure were the interventions that proved to be effective. Less than half of studies reported adverse effects, with mild and transient symptoms predominating. Most articles were classified as "some concern" in risk of bias assessment. CONCLUSION: the three most effective interventions to control gestational nausea and vomiting were aromatherapy, herbal medicine and acupuncture, with significant results in the assessment of individual studies.

Dietary strategies for chemotherapy-induced nausea and vomiting: A systematic review.

BACKGROUND & AIMS: Chemotherapy-induced nausea and vomiting (CINV) is one of the most distressing cancer treatment side effects, affecting 20-70% of patients despite routine antiemetic prescription. Although dietary modifications are routinely recommended in clinical practice, there is lack of data synthesis to determine which dietary strategies for managing CINV are supported by quality evidence. This systematic review was conducted to examine the effect of dietary strategies on incidence and severity of CINV in adults compared with no intervention, usual care, or alternative strategies. METHODS: Five electronic databases were searched from inception to 15th July 2021 for original research studies of interventional or observational design assessing dietary strategies for CINV. The quality of evidence was appraised, data were synthesized narratively, and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) assessment of the certainty of the evidence was applied. RESULTS: Twenty-one studies were included, 10 (48%) interventional studies and 11 (52%) observational studies. Most interventional and observational studies had a high or neutral risk of bias (70% and 72%, respectively). Of the interventions studied, strongest evidence with highest certainty was found for the very large positive effect of CINV-specific education and support with a personalized meal plan from a dietician, implemented in person or in writing, for reducing the severity of nausea and overall CINV (effect size: very large; GRADE: high). A statistically significant very large positive effect of ginger tea consumption was also found on overall CINV severity; however, certainty in this effect was very low. Although confidence in the findings from observational studies was very low to low, a statistically significant positive association was also found between a moderate intake of alcohol and incidence of nausea, vomiting, or overall CINV as well as nausea severity; the Mediterranean diet and nausea incidence and severity; and adequate intake of energy, protein, fat, or carbohydrate and nausea or vomiting incidence. CONCLUSION: Improved CINV was associated with CINV-specific nutrition education and support from health professionals. Non-restrictive dietary patterns that include adequate energy and macronutrient intakes, particularly protein, and include ginger, and Mediterranean diet concepts may benefit CINV; however, the confidence in the body of evidence to inform these conclusions is mostly very low to moderate. Future rigorous trials with adequate sample sizes, clearly defined dietary strategies, and valid outcome measures are warranted prior to dietary strategies being routinely prescribed alongside antiemetic regimens.

Chemotherapy-Associated nausea and vomiting: A cross-sectional survey of occurrence and management patterns at jos university teaching hospital, Nigeria.

Background: The management patterns for chemotherapy-associated nausea and vomiting (CANV) in Sub-Saharan African settings have not been previously reported. The objectives of this study were to describe the prescribing pattern of antiemetics for CANV, to assess their adherence to guidelines, and to determine the occurrence of CANV. Subjects and Methods: This was a cross-sectional study, with data extracted from the records of adult patients who received chemotherapy from 2015 to 2018 at Jos University Teaching Hospital, Nigeria. The National Comprehensive Cancer Network Harmonized Guidelines™ for Sub-Saharan Africa for Antiemesis Version 3.2018 was used to determine the extent of guideline adherence. Results: Records of 165 patients were analyzed. Majority of the patients (76.4%, n = 126) received moderate-to-high emetic risk intravenous (IV) chemotherapy. Out of 129 antiemetic prescriptions for acute-phase prophylaxis, ondansetron (75.2%), corticosteroids (61.2%), and promethazine (24.8%) were the most prescribed agents. In the delayed phase, 50 patients received prophylactic antiemetics in the order of corticosteroids, ondansetron, and promethazine at 74%, 34%, and 26%, respectively. Guideline adherence was low for the acute-phase (23.6%), delayed-phase (20.6%), and overall period (17.6%). Among inpatients (n = 85), occurrences of nausea were negligible, whereas acute vomiting (9%) and delayed vomiting (15%) levels were considerable. Not receiving highly emetogenic IV chemotherapy was associated with significantly lower odds for nausea or vomiting occurrence, odds ratio 0.228 (95% confidence interval 0.054-0.967). Conclusions: Antiemetic guideline adherence was low due to antiemetic under-prescribing. A few nausea and vomiting events were recorded predominantly among patients who received highly emetogenic IV chemotherapy.

Effect of electroacupuncture on discomfort during gastroscopy: a study protocol for a randomized controlled trial.

BACKGROUND: Gastroscopy procedures are frequently performed under general sedation to minimize discomfort. Patients who refuse a sedative injection may experience more discomfort and adverse reactions such as pain and nausea. These instances reduce patient compliance and willingness to participate in future procedures. Acupuncture has been shown to have an anti-nausea and analgesic effect; however, there is limited data available that demonstrates the efficacy of acupuncture when applied before gastroscopy. METHODS: A total of 60 participants will be randomly assigned to the electroacupuncture (EA) group and the sham electroacupuncture (SEA) group at a ratio of 1:1. Acupuncture treatment will be performed before gastroscopy for a duration of 30 min. All patients will complete detailed questionnaires at 30 min and 7 days post-procedure to record the severity of their symptoms. The primary outcome will be the average of 4 standard visual analogue scale (VAS) scores in the categories of nausea, vomiting, throat discomfort, and agitation as reported by the patient. The secondary outcomes will be patient's anxiety level as recorded by the 6-item short form of the State-Trait Anxiety Inventory (STAI-S6) and Amsterdam Pre-Operative Anxiety and Information Scale (APAIS), preference in a future endoscopy, pulse oxygen saturation (SpO2), heart rate (HR), and blood pressure (BP). Anxiety scales will be assessed before and after acupuncture; others will be completed at 30 min and 7 days post-procedure. The duration of the gastroscopy and the number of biopsies will be recorded after operation. DISCUSSION: This randomized controlled trial will explore the feasibility of the further clinical application of electroacupuncture for the improvement of patient discomfort during gastroscopy without systemic sedation. TRIAL REGISTRATION: ChiCTR2000040726 .

Psychological Interventions in Chemotherapy-Induced Nausea and Vomiting in Women with Breast Cancer: A Systematic Review.

Background: Nausea and vomiting are considered the most common side effects of chemotherapy, and they can affect different dimensions of the lives of women with breast cancer. Thus, the management of these complications is of great significance. Various interventions are drawn upon to alleviate nausea and vomiting. This review aimed to investigate the effects of psychological interventions on chemotherapy-induced nausea and vomiting among women with breast cancer. Methods: A systematic review of clinical or quasi-experimental clinical trials published from 2000 to 2020 on the effects of psychological interventions on nausea and vomiting induced by chemotherapy in women with breast cancer was conducted via a comprehensive search in web search engines including Google Scholar and PubMed and databases such as Web of Science, Scopus, ScienceDirect, Cochrane Library, Springer, Elsevier, Magiran, and Scientific Information Database (SID). Medical Subject Heading (MeSH) was employed with the following keywords: nausea, vomiting, breast cancer, chemotherapy, and psychological intervention. The quality of the included studies was assessed via the Jadad scale. Results: Nine studies were included in this systematic review. Psychological interventions in chemotherapy-induced nausea and vomiting in women with breast cancer consisted of cognitive-behavioral therapy, progressive muscle relaxation training, yoga, and guided imagery. The results indicated that in all the studies, except one, the interventions improved conditions and reduced chemotherapy-induced nausea and vomiting. Conclusion: The results of this study indicated that psychological interventions such as cognitive-behavioral therapy, progressive muscle relaxation training, guided imagery, and yoga alleviated nausea and vomiting induced by chemotherapy in women with breast cancer. Therefore, it is recommended that these interventions be applied by healthcare providers to ameliorate nausea and vomiting in these patients.The abstract was presented in the 15th International Congress on Obstetrics and Gynecology, Tehran, Iran, 8-11 October 2019, as a poster and published in the congress book.

The Prevention and Treatment of Nausea and Vomiting During Tumor Therapy.

BACKGROUND: Nausea and vomiting are common and distressing side effects of tumor therapy. Despite prophylaxis, 40-50% of patients suffer from nausea, and 20-30% from vomiting. Antiemetic prophylaxis and treatment are therefore of great importance for improving patients' quality of life and preventing sequelae such as tumor cachexia. METHODS: The recommendations presented here are based on international and national guidelines, updated with publications retrieved by a selective search in the PubMed and Cochrane Library databases, with special attention to randomized controlled trials and meta-analyses that have appeared in the past 5 years since the German clinical practice guideline on supportive therapy was published. RESULTS: Risk-adjusted prevention and treatment is based on the identification of treatment-related and patient-specific risk factors, including female sex and younger age. Parenteral tumor therapy is divided into four risk classes (minimal, low, moderate, high), and oral tumor therapy into two (minimal/low, moderate/high). In radiotherapy, the radiation field is of decisive importance. The antiemetic drugs most commonly used are 5-HT3-RA, NK1-RA, and dexamethasone; olanzapine has proven beneficial as an add-on or rescue drug. The use of steroids in patients being treated with drug combinations including checkpoint inhibitors is discussed controversially because of the potentially reduced therapeutic response. Benzodiazepines, dimenhydrinate, and cannabinoids can be used as backup antiemetics. Acupuncture/acupressure, ginger, and progressive muscle relaxation are pos - sible alternative methods. CONCLUSION: Detailed, effective, risk profile-adapted algorithms for the prevention and treatment of nausea and vomiting are now available for patients undergoing classic chemotherapy regimens or combined radiotherapy and chemotherapy. Optimal symptom control for patients undergoing oral tumor therapy over multiple days in the outpatient setting remains a challenge.

A Scoping Review of Biological Pathways of Integrative Interventions Used to Manage Chemotherapy-Induced Nausea and Vomiting in Children With Cancer.

BACKGROUND: As with pharmacological management approaches, characteristics of complementary and alternative medicine (CAM) interventions for managing chemotherapy-induced nausea and vomiting (CINV) in children with cancer should be considered when developing and testing these interventions and reporting the outcomes. OBJECTIVES: This systematic scoping review aimed to identify gaps and weaknesses in CAM and integrative interventions studies to prevent and manage CINV in children being treated for cancer, according to the CINV biological pathways. METHODS: This systematic scoping review was conducted under the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guideline. Included studies were published in English before May 2020 and examined the effects of integrative interventions on CINV in children being treated for cancer. Two authors performed computerized searches and manual reviews; these authors also extracted data about study characteristics, intervention characteristics, and CINV outcomes from the studies included in the review. RESULTS: Twenty-six studies of 29 CAM interventions met eligibility criteria. Most of these studies used randomized controlled trial designs and measured CINV outcomes at least once prior to and then after the intervention. Some studies did not explicate the interval between exposure to the intervention and outcome measurements. The CAM interventions studied included 15 cognitive-behavioral interventions, 8 acupoint stimulation interventions, 5 herb/supplementation interventions, and 1 educational intervention. One study tested two CAMs and clarified the underlying biological pathways, whereas 25 studies (27 CAMs) did not illustrate pathways; the pathways were deduced from information provided in the articles. DISCUSSION: Considering the biological pathways underlying CINV while developing integrative interventions, including the CAM component, could improve intervention efficacy. Measurement of biomarkers of activity in these pathways would provide a means to test whether changes in underlying pathways mediate change in CINV. Better reporting of intervention details and study processes is needed to support replication of CAM interventions and inform translation into clinical practice.

Acupuncture as a tool to reduce nausea in terminally ill patients.

AIM: To investigate if acupuncture reduces nausea and vomiting in terminally ill patients. DESIGN: A comparative effectiveness research design was used to generate evidence-based knowledge close to practice for the use of clinicians. The sample size was calculated to 136 patients randomised into an intervention and a control group, respectively. Nausea and vomiting were measured using the EORTC QLQ-c15-PAL (European Organisation for Research and Treatment of Cancer, Quality of Life Questionnaire, core 15, Palliation). LOCATION: The trial was conducted among terminally ill patients admitted to three in-bed hospices in Demark. PARTICIPANTS: Terminally ill patients suffering from nausea and/or vomiting; 95% of patients had cancer. INTERVENTION: The intervention group received acupuncture in addition to usual care for three days. We used the acupuncture spots: Pericardium-6, Stomach-36, Liver-3 and Yin Tang. The control group received usual care only. RESULTS: In total, 136 patients were randomised, 24 patients withdrew resulting in a total sample of 112 patients: 52 patients in the intervention group and 60 patients in the control group. In the intervention group, 75% of the patients experienced a reduction of their nausea score after the intervention compared to 55% in the control group. The statistical difference was p = 0.028. In the intervention group, 52% of the patients did not experience nausea at all after the intervention compared to 30% in the control group. In the intervention group, 31% of the patients were still vomiting after the intervention compared to 34% in the control group; no statistically significant difference was found. CONCLUSION: Acupuncture reduced the experience of nausea among terminally ill patients but did not reduce vomiting. Thus, acupuncture is recommended to reduce nausea among terminally ill patients.
