OBJECTIVES: To observe the efficacy and safety of ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation in the prevention and treatment of chemotherapy-induced nausea and vomiting (CINV) in patients with malignant tumors. METHODS: Patients with malignant tumors and suffering from chemotherapy were randomly divided into control group (35 cases, 4 cases dropped off) and observation group (35 cases, 2 cases dropped off). The patients of the control group were treated by orally taking ondansetron hydrochloride tablets 8 mg/time, 3 times a day for 3 d, and those of the observation group treated by ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation of Zusanli(ST36), Neiguan(PC6), Tianshu(ST25), Zhongwan(CV12) and Guanyuan(CV4) once a day for a total of 3 d, based on the treatment of the control group. The patients' gastrointestinal reaction degree after the 1st , 2nd and the 3rd day of treatment were recorded. The Karnofsky performance status (KPS) score (0-100 points) was used for assessing the patients' quality of life. The TCM syndrome score (4 grades：no, mild, medium and severe, i.e. 0, 2, 4 and 6 points) was given according to the patients' severity of symptoms of spleen (stomach) qi deficiency (nausea and vomiting, abdominal distension after eating, belching, loss of appetite, weakness and laziness to speak, fatigue, and loose stool). The safety of the treatment was assessed by examining the patients' blood routine, liver function and kidney function, and the adverse reactions including blisters, allergies, burns and fainting during acupuncture treatment. RESULTS: After the 2nd and 3rd day of treatment, the patients conditions of vomiting and nausea in the observation group were significantly better than those of the control group (P<0.05). The TCM syndrome score and KPS score were significantly decreased in comparison with those of pre-treatment in both groups (P<0.05), and the TCM syndrome score was obviously lower in the observation group than in the control group (P<0.05). No significant differences were found between the two groups in the KPS score after the treatment , and in the levels of white blood cells (WBC), hemoglobin (HGB), platelets (PLT), absolute neutrophil count (ANC), alanine transaminase (ALT), aspartate aminotransferase (AST), creatinine(Cr), and blood urea nitrogen (BUN). CONCLUSIONS: The use of ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation is safe for CINV patients, and can effectively relieve nausea and vomiting and alleviate digestive symptoms.

Differences in severity of chemotherapy-induced nausea and vomiting between neoadjuvant and adjuvant chemotherapy in patients with breast cancer: analysis of data from two prospective observational studies.

PURPOSE: We assessed the differences in chemotherapy-induced nausea and vomiting (CINV) severity in patients with breast cancer, receiving neoadjuvant chemotherapy (NAC) and adjuvant chemotherapy (AC). METHODS: CINV severity in patients on anthracycline-based NAC (n = 203) and AC (n = 79) was assessed at baseline (C0) and after the first and fourth chemotherapy using a 10-point Likert scale. Group-by-time interaction term was used to evaluate the effect of the group on changes in CIN (cCIN) and CIV (cCIV) from C0 to the follow-up periods (C1, C4). If insignificant, group effects were analyzed without the interaction term. Subgroup analysis was performed based on age 50. In statistical analyses, sociodemographic and clinical variables that differed between groups were adjusted for. RESULTS: The effect of group by follow-up period was not significant in cCIN and cCIV. The AC group showed a significantly higher change in the severity of cCIN compared to the NAC group (estimated mean = 1.133, 95% CI = 0.104-2.161, p = 0.031), but there was no difference in cCIV. In those ≤ 50 years, significant differences in cCIN severity (estimated mean = 1.294, 95% CI = 0.103-2.484, p = 0.033) were observed, but not in cCIV. In those > 50 years, neither cCIN nor cCIV differed significantly between groups. CONCLUSIONS: NAC in breast cancer patients showed less severe CIN than adjuvant chemotherapy AC, but not in those over 50. Clinicians should recognize that the severity of CIN may vary across different chemotherapy settings and adjust their management accordingly. TRIAL REGISTRATION: The clinical trial registration ( www. CLINICALTRIALS: gov ) numbers were NCT01887925 (the registration date is from June 20, 2013, to November 27, 2015) and NCT02011815 (the registration date is from December 10, 2013, to September 22, 2019).

Association between a past history of nausea and vomiting during pregnancy and fever after the BNT162b2 COVID-19 vaccination.

PURPOSE: Nausea and vomiting during pregnancy (NVP) are common among pregnant women and can be severe enough to require hospitalization. However, the mechanism underlying NVP pathogenesis remains unclear. This study examined factors associated with adverse events after vaccination, including a past history of NVP. METHODS: A questionnaire-based survey was completed by non-pregnant women working at Nagasaki University Hospital who received two doses of the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine. This study primarily examined the association between a past history of NVP and post-vaccination fever, as fever was determined to be the most objective and reliable indicator of the surveyed adverse events. RESULTS: Multivariate logistic regression analysis showed that post-vaccination fever was more strongly associated with a past history of NVP (odds ratio, 1.88; 95% confidence interval, 1.16-3.07) than either age (0.73; 0.56-0.96) or weight (0.85; 0.70-1.15), which were previously considered to be highly associated with the incidence of adverse events following COVID-19 vaccination. CONCLUSION: These results suggest an involvement of a similar pathological condition in developing NVP and post-vaccination fever.

Gastrointestinal and Neuropsychological Symptoms Are Associated With Distinct Vomiting Profiles in Patients Receiving Chemotherapy.

OBJECTIVES: To identify subgroups of patients with distinct chemotherapy-induced vomiting (CIV) profiles; determine how these subgroups differ on several demographic, clinical, and symptom characteristics; and evaluate factors associated with chemotherapy-induced nausea and CIV profiles. SAMPLE & SETTING: Adult patients (N = 1,338) receiving cancer chemotherapy. METHODS & VARIABLES: Data were collected on demographic, clinical, and symptom characteristics. Differences among subgroups of patients with distinct CIV profiles were evaluated using parametric and nonparametric tests. RESULTS: Three CIV profiles (None, Decreasing, and Increasing) were identified. Compared with the None class, Decreasing and Increasing classes were more likely to have lower household income and a higher comorbidity burden, as well as to report higher rates of dry mouth, nausea, diarrhea, depression, anxiety, sleep disturbance, morning fatigue, and pain interference. IMPLICATIONS FOR NURSING: Clinicians need to assess common and distinct risk factors for CIV and chemotherapy-induced nausea.

Acupoint Application Combined with Acupressure as an Adjunctive Therapy for Chemotherapy-induced Nausea and Vomiting.

Chemotherapy-induced nausea and vomiting (CINV) refers to the nausea and vomiting experienced by patients after the application of chemotherapy drugs, significantly affecting their quality of life and physical recovery, as well as increasing the pain of the patients. Basic medicine primarily focuses on acid suppression, gastric protection, and vomiting suppression, but there are still many patients with nausea and vomiting symptoms that cannot be alleviated. Traditional Chinese medicine (TCM) can effectively alleviate nausea and vomiting through acupoint stimulation and pressure, while also offering advantages such as simplicity, affordability, and fewer side effects. The aim of this article is to introduce the method of using acupoint application combined with acupressure as an adjunctive therapy for CINV, using the Multinational Association of Supportive Care in Cancer (MASCC) Antiemesis Tool (MAT) tablet scale as a questionnaire. The article details aspects such as acupoint selection, production, and the use of acupoint application, massage techniques, and operating procedures, all with the goal of ensuring the safety and efficacy of acupoint application combined with acupressure as an adjuvant therapy, thereby improving patients' clinical symptoms and quality of life.

Association of the OPRM1 variant rs1799971 (A118G) and clinical manifestations in tramadol poisoned patients: a cross-sectional study.

INTRODUCTION: The opioid receptor mu1 is a protein coding gene that can have different codes for a protein and may have variations (polymorphisms) affecting how opioids work. The aim of this study was to investigate the prevalence of the most common opioid receptor mu1 polymorphism (A118G) and any relationship between this polymorphism and features following tramadol overdose. MATERIALS AND METHODS: This was a cross-sectional study of patients admitted with tramadol poisoning to an Iranian hospital. These patients were not taking any other drugs or medications and had no history of seizures. RESULTS: The results showed that among the 83 patients included in the study, 57 (69 per cent) had the AA genotype, 25 (30 per cent) had the AG genotype, and one (1 per cent) had the GG genotype for the opioid receptor mu1 A118G polymorphism. Nausea and/or vomiting occurred in nine (11 per cent) patients and dizziness in 38 (46 per cent) patients. Serious adverse events included seizures in 51 (60 per cent) patients and respiratory failure requiring mechanical ventilation in 21 (25 per cent) patients. However, there was no significant association between the opioid receptor mu1 A118G polymorphism and these adverse events. DISCUSSION: In our study, the frequency of the A allele was greater than the G allele, and the AA genotype was more prevalent than AG. The GG genotype was the least common among the polymorphisms of opioid receptor mu1 rs1799971. There was no significant association between the opioid receptor mu1 A118G polymorphism and symptoms in tramadol-poisoned patients. Although these allele proportions are similar to the results reported in other Caucasian populations, they are dissimilar to the findings in Chinese and Singaporean populations. In these Asian studies, the predominant allele was the G allele. It has been suggested that a mutated G allele will decrease the production of opioid receptor mu1-related messenger ribonucleic acid and related proteins, leading to fewer mu-opioid receptors in the brain. CONCLUSIONS: This study found no significant association between the opioid receptor mu1 A118G polymorphism and adverse outcomes in tramadol-poisoned patients. However, more research is needed to draw more definitive conclusions due to the limited evidence and variability of opioid receptor mu1 polymorphisms in different populations.

Risk factors for nausea and vomiting requiring the daily administration of 5-HT3 receptor antagonists in radiotherapy combined with temozolomide for high-grade glioma.

Radiotherapy combined with temozolomide (TMZ+RT) is the primary treatment for high-grade glioma. TMZ is classified as a moderate emetic risk agent and, thus, supportive care for nausea and vomiting is important. In Nagoya University Hospital, all patients are treated with a 5-hydroxy-tryptamine 3 receptor antagonist (5-HT3RA) for the first 3 days. The daily administration of 5-HT3RA is resumed after the 4th day based on the condition of patients during TMZ+RT. Therefore, the present study investigated risk factors for nausea and vomiting in patients requiring the daily administration of 5-HT3RA. Patients with high-grade glioma who received TMZ+RT between January 2014 and December 2019 at our hospital were included. Patients were divided into two groups: a control group (patients who did not resume 5-HT3RA) and resuming 5-HT3RA group (patients who resumed 5-HT3RA after the 4th day), and both groups were compared to identify risk factors for nausea and vomiting during TMZ+RT. There were 78 patients in the control group (68%) and 36 in the resuming 5-HT3RA group (32%). A multivariate analysis of patient backgrounds in the two groups identified age <18 years, PS 2 or more, and occipital lobe tumors as risk factors for nausea and vomiting. Nausea and vomiting were attenuated in 30 patients (83%) in the resuming 5-HT3RA group following the resumption of 5-HT3RA. The results obtained highlight the importance of extracting patients with these risk factors before the initiation of therapy and the early resumption or daily administration of 5-HT3RA according to the condition of each patient.

Nausea and vomiting in pregnancy (NVP) in Chinese pregnant women: a cross-sectional study.

BACKGROUND: This study addresses the scarcity of research on nausea and vomiting in pregnancy (NVP) in China. It aims to explore the current NVP status in the country using validated questionnaires, analyze associated factors, and provide a useful reference for future research. The study also compares results from different assessment tools. METHODS: Online questionnaires were utilized to gather data from 535 pregnant women across 24 provinces. Demographic, pregnancy, and NVP-related information were collected. NVP severity was assessed using Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) and the Rhodes Index of Nausea, Vomiting, and Retching (RINVR) scales. Ordinal logistic regression identified factors linked to NVP severity. Differences between PUQE and RINVR assessments were compared. RESULTS: NVP prevalence exceeded 90%, with 96.1% assessed by PUQE and 90.8% by RINVR. Incidence decreased from nausea to retching and vomiting. Severe NVP correlated with reduced gestational weight gain, younger age, fewer gestational weeks, and living in North (all P values < 0.05). There was moderate consistency between PUQE and RINVR assessments. The NVP prevalence assessed by the PUQE is higher than that assessed by the RINVR in the same population. However, the proportion of NVP levels above moderate assessed by RINVR is greater than that assessed by PUQE. CONCLUSIONS: NVP is highly prevalent among Chinese pregnant women, with nausea being predominant. RINVR assessments may be better able to identify severe NVP, thereby improving the low treatment rates for severe NVP.

Prolonged administration of the granisetron transdermal delivery system reduces capecitabine plus oxaliplatin regimen induced nausea and vomiting.

OBJECTIVE: To evaluate the safety and efficacy of the granisetron transdermal delivery system (GTDS) combined with Dexamethasone for preventing chemotherapy-induced nausea and vomiting (CINV) in patients receiving Capecitabine plus Oxaliplatin (CapeOX) therapy. DESIGN: Open-label, prospective, multi-center phase II trial. SETTING: Three institutions. PARTICIPANTS: Fifty-four patients scheduled to receive CapeOX chemotherapy. INTERVENTIONS: Participants received GTDS (3.1 mg applied to the upper arm 48 h before chemotherapy, replaced on day 5, and discarded on day 12) and Dexamethasone. MAIN OUTCOME MEASURES: The primary endpoint was the complete control rate of CINV. Secondary endpoints included the duration of delayed complete control, complete control rate in the acute phase, safety, and quality of life. RESULTS: The complete control rate for delayed CINV over the entire period (25-480 h) was 72.7% (95% CI 0.57-0.88). The duration of delayed complete control was 17.2 ± 4.5 days, with 51.5% of patients experiencing no nausea during the delayed phase. The complete control rate in the acute phase was 81.8% (95% CI 0.69-0.95). No serious adverse events related to the antiemetic regimen were reported. CONCLUSION: Prolonged administration of GTDS is safe and effective for preventing CINV in patients with gastrointestinal malignancies treated with CapeOX. TRIAL REGISTRATION: ClinicalTrials.gov registry (NCT05325190); registered on October 10, 2021.

Laparoscopic repair of Morgagni hernia by primary closure with extra-abdominal suture: a case report and review of the literature.

We report a case of a Morgagni hernia repaired by primary closure with an extra-abdominal suture. Moreover, we reviewed cases of laparoscopically repaired Morgagni hernia, in which the size of the hernia defect was known, to establish a size criterion for mesh utilization. An 87-year-old woman presented to our hospital with right upper abdominal pain and vomiting. She had no history of abdominal surgery or trauma. Chest radiography and computed tomography (CT) revealed a Morgagni hernia, with the stomach and transverse colon herniated into the right chest cavity. Initially, an endoscopic repair was performed for the herniated stomach due to her age, which was successful. However, she had a recurrence 2 days later, prompting us to perform a semi-emergent laparoscopic surgery. Laparoscopic examination revealed a Morgagni defect, with the omentum, transverse colon, and stomach herniated, with the stomach reduced by pneumoperitoneum. Fortunately, the herniated organs could be easily relocated into the abdomen with no adhesions. The hernia defect measured 6 x 3 cm. We performed primary closure with an extra-abdominal suture. No sac resection was performed. The operation lasted 98 min. Oral intake was initiated on postoperative day 1, and the patient was discharged on postoperative day 3 without complications. Chest radiography and CT scans at 1 month postoperatively showed no recurrence, and the patient remained asymptomatic at the 9-month follow-up examination. According to our review findings, primary closure is an efficient method for small hernia defects (rule of thumb: width, <4 cm; length, <7 cm).

Pharmacological treatment of cancer pain and opioid induced nausea and vomiting: online survey and comparison with current guidelines.

PURPOSE: We assumed that in Palliative Care, even in common clinical situations, the choice of drugs differs substantially between physicians. Therefore, we assessed the practice of pharmaceutical treatment choices of physicians for cancer pain and opioid-induced nausea and vomiting (OINV) and the rationale for their choices. METHODS: An online survey was conducted with physicians covering the following domains: i) Cancer pain therapy: non-opioids in addition to opioids: choice of drug ii) prevention of OINV: choice of drug and mode of application. Current guidelines concerning cancer pain therapy and prevention of OINV were compared. RESULTS: Two-hundred-forty European physicians responded to our survey. i) Use of non-opioids in addition to opioids for the treatment of cancer pain: Only 1.3% (n = 3) of respondents never used an additional non-opioid. Others mostly used: dipyrone/metamizole (49.2%, n = 118), paracetamol/acetaminophen (34.2%, n = 82), ibuprofen / other NSAIDs (11.3%, n = 27), specific Cox2-inhibitors (2.1%, n = 5), Aspirin (0.4%, n = 1), no answer (2.9%, n = 7). ii) Antiemetics to prevent OINV: The drugs of choice were metoclopramide (58.3%, n = 140), haloperidol (26.3%, n = 63), 5-HT3 antagonists (9.6%, n = 23), antihistamines (1.3%, n = 3) and other (2.9%, n = 7); no answer (1.7%, n = 4). Most respondents prescribed the substances on-demand (59.6%, n = 143) while others (36.3%, n = 87) provided them as around the clock medication. Over both domains, most physicians answered that their choices were not based on solid evidence from randomized controlled trials (RCTs). Guidelines were inconsistent regarding if and what non-opioid to use for cancer pain and recommend anti-dopaminergic drugs for prevention or treatment of OINV. CONCLUSIONS: Physician's practice in palliative care for the treatment of cancer pain and OINV differed substantially. Respondents expressed the lack of high-quality evidence- based information from RCTs. We call for evidence from methodologically high-quality RCTs to be available to inform physicians about the benefits and harms of pharmacological treatments for common symptoms in palliative care.

Outcomes of chemotherapy-induced nausea and vomiting guideline adherence in pediatric and adult patients: a systematic review.

PURPOSE: This study describes chemotherapy-induced nausea and vomiting (CINV) control rates in pediatric and adult patients who did or did not receive guideline-consistent CINV prophylaxis. METHODS: We conducted a systematic literature review of studies published in 2000 or later that evaluated CINV control in patients receiving guideline-consistent vs. guideline-inconsistent CINV prophylaxis and reported at least one CINV-related patient outcome. Studies were excluded if the guideline evaluated was not publicly available or not developed by a professional organization. Over-prophylaxis was defined as antiemetic use recommended for a higher level of chemotherapy emetogenicity than a patient was receiving. RESULTS: We identified 7060 citations and retrieved 141 publications for full-text evaluation. Of these, 21 publications (14 prospective and seven retrospective studies) evaluating guidelines developed by six organizations were included. The terms used to describe CINV endpoints and definition of guideline-consistent CINV prophylaxis varied among studies. Included studies either did not address over-prophylaxis in their definition of guideline-consistent CINV prophylaxis (48%; 10/21) or defined it as guideline-inconsistent (38%; 8/21) or guideline-consistent (3/21; 14%). Eleven included studies (52%; 11/21) reported a clinically meaningful improvement in at least one CINV endpoint in patients receiving guideline-consistent CINV prophylaxis. Ten reported a statistically significant improvement. CONCLUSIONS: This evidence supports the use of guideline-consistent prophylaxis to optimize CINV control. Institutions caring for patients with cancer should systematically adapt CINV CPGs for local implementation and routinely evaluate CINV outcomes.

Unusual neonatal case of superior mesenteric artery syndrome with Meckel's diverticulum and literature review.

Superior mesenteric artery syndrome (SMAS) is a rare cause of duodenal obstruction which is characterized by compression of the duodenum due to narrowing of the space between the superior mesenteric artery and aorta. Incomplete duodenal obstruction due to SMAS in neonates is rarely reported in the literature. In this case, it is a full-term 2-day-old male with the complaint of recurrent vomiting starting soon after birth. The patient was diagnosed with SMAS and duodenoduodenostomy was performed. Accompanying Meckel's diverticulum was excised.

El síndrome de la arteria mesentérica superior (SMAS) es una causa rara de obstrucción duodenal que se caracteriza por la compresión del duodeno debido al estrechamiento del espacio entre la arteria mesentérica superior y la aorta. La obstrucción duodenal incompleta por SMAS en recién nacidos rara vez se informa en la literatura. En este caso se trata de un varón de 2 días nacido a término que presenta vómitos recurrentes desde poco después del nacimiento. El paciente fue diagnosticado de SMAS y se le realizó duodenoduodenostomía. Se extirpó el divertículo de Meckel que lo acompañaba.

Primary achalasia diagnosed during pregnancy: rare cause of nausea and vomiting.

Nausea and vomiting during pregnancy are very common; however, when persistent symptoms lead to severe malnutrition, other conditions should be considered. We present a patient with severe postprandial nausea and vomiting resulting in 120 lb weight loss. She was treated for presumed hyperemesis gravidarum but diagnosed with achalasia type 1 upon further work-up. The pregnancy was further complicated by fetal growth restriction, shortened cervix and preterm premature rupture of membranes, and resulted in delivery at 26 weeks of gestation. Postpartum, she underwent a peroral endoscopic myotomy procedure and has returned to normal body mass index.The differential for nausea/vomiting is broad, and major medical conditions can manifest for the first time during pregnancy. Severe malnutrition adversely affects maternal and fetal health. Further work-up should be pursued when symptoms cannot otherwise be explained.

Randomized Placebo-Controlled Trial of Topical Capsaicin for Delayed Chemotherapy-Induced Nausea and Vomiting.

PURPOSE: We examined the efficacy of topical capsaicin in reducing delayed chemotherapy-induced nausea and vomiting (CINV). METHODS: Adults on highly emetogenic chemotherapy regimens applied 2 g of capsaicin ointment (0.075%) or matching placebo four times a day to the abdomen for 5 days in addition to standard antiemetic regimen in this blinded randomized controlled trial. Patients were monitored for nausea and vomiting in the immediate (day 1), delayed (days 2-5), and extended phases (days 2-15). Self-reported incidence and daily episodes of CINV were compared between the groups. Onset, severity, need for rescue antiemetics, cumulative vomiting episodes, and safety were also compared. RESULTS: In total, 160 patients were enrolled. The final modified intention-to-treat population included 75 patients each in the capsaicin and placebo groups. Fewer patients experienced nausea (36.0% [n = 27] v 53.3% [n = 40]; P = .033) and vomiting (28.0% [n = 21] v 42.7% [n = 32]; P = .060) in the capsaicin arm during the delayed phase. During the extended phase, there was a significantly lower incidence of nausea (44% v 64.0%; P = .014) in the capsaicin arm. No difference in nausea (26.7% v 25.3%) or vomiting (22.7% v 18.7%) was evident in the immediate phase. The average daily episodes of nausea and vomiting were significantly fewer in the capsaicin arm during the delayed and extended phases. With capsaicin, no grade 3 nausea (9.3% v 0.0%; P = .007) was observed, and the time to first nausea and vomiting was significantly prolonged. There were no differences between the groups with respect to rescue antiemetics, unscheduled hospital visits, and adverse events. CONCLUSION: Topical capsaicin reduced the incidence of nausea and the average number of vomiting episodes during delayed and extended phases without increasing adverse effects.

Pharmacokinetics, pharmacodynamics, safety, and tolerability of dopamine-receptor antagonists for the prevention of chemotherapy-induced nausea and vomiting.

INTRODUCTION: Dopamine (D)2,3-receptor antagonists (RAs) were the first antiemetics used in the prophylaxis of chemotherapy-induced nausea and vomiting (CINV). AREAS COVERED: Eight D2,3-RAs, amisulpride, domperidone, droperidol, haloperidol, metoclopramide, metopimazine, olanzapine and prochlorperazine are reviewed focusing on pharmacokinetics, pharmacodynamics, antiemetic effect and side effects. EXPERT OPINION: Since the introduction of D2,3-RAs, antiemetics such as corticosteroids, 5-hydroxytryptamine (5-HT)3-RAs and neurokinin (NK)1-RAs have been developed. The classical D2,3-RAs are recommended in the prophylaxis of CINV from low emetic risk chemotherapy, but not as a fixed component of an antiemetic regimen for moderately or highly (HEC) emetic risk chemotherapy. D2,3-RAs are also used in patients with breakthrough nausea and vomiting. It should be emphasized, that most of these drugs are not selective for dopamine receptors.The multi-receptor targeting agent, olanzapine, is recommended in the prophylaxis of HEC-induced CINV as part of a four-drug antiemetic regimen, including a 5-HT3-RA, dexamethasone and a NK1-RA. Olanzapine is the most effective agent to prevent chemotherapy-induced nausea.Side effects differ among various D2,3-RAs. Metopimazine and domperidone possess a low risk of extrapyramidal side effects. Domperidone and metoclopramide are prokinetics, whereas metopimazine delays gastric emptying and haloperidol does not influence gastric motility. Many D2,3-RAs increase the risk of prolonged QTc interval; other side effects include sedation and orthostatic hypotension.

Evaluation of Efficacy of Adding Aprepitant to Palonosetron and Dexamethasone in Carboplatin and Etoposide Therapy.

Although carboplatin (CBDCA) is classified as a moderately emetogenic agent, the majority of guidelines recommend the use of a neurokinin-1 receptor antagonist in addition to a 5-hydroxytryptamine type 3 receptor antagonist with dexamethasone (DEX) for CBDCA-containing chemotherapy because of its higher emetogenic risk. However, the additional efficacy of aprepitant (APR) in CBDCA-containing treatment remains controversial, and data on multiple-day treatments are limited. Etoposide (ETP) was administered on days 1-3 in the CBDCA + ETP regimen, and it is important to evaluate suitable antiemetic therapy for the regimen. Therefore, we evaluated the efficacy of additional APR in CBDCA + ETP. Patients were divided into two groups and retrospectively evaluated. One was the control group, which was prophylactically administered palonosetron (PALO) and DEX, and the other was the APR group, which received APR orally with PALO and DEX. The primary endpoint was complete response (CR) between the groups. The overall CR rates were 75.0 and 76.4% in the control and APR groups, respectively, with no significant difference (p = 1.00). In the acute phase, it was 88.9 and 97.2%, respectively, and 86.1 and 79.2% in the delayed phase, respectively, without significant differences (p = 0.10 and 0.38, respectively). The incidence and severity of nausea, vomiting, and anorexia were not significantly different between the two groups in the acute and delayed phases. Our findings suggest that combining APR with PALO and DEX does not improve the CR rate in CBDCA + ETP therapy.
