ABSTRACT
BACKGROUND: Anticipatory chemotherapy-induced nausea and vomiting (CINV) is a conditioned response influenced by the severity and duration of previous emetic responses to chemotherapy. We aimed to evaluate the efficacy of non-pharmacologic interventions for anticipatory CINV among patients with cancer. METHODS: We conducted a systematic search in databases, including PubMed, the Cochrane Library, CINAHL, and Ichushi-Web, from January 1, 1990, to December 31, 2020. Randomized controlled trials, non-randomized designs, observational studies, or case-control studies that utilized non-pharmacological therapies were included. The primary outcomes were anticipatory CINV, with an additional investigation into adverse events and the costs of therapies. The risk-of-bias for each study was assessed using the Cochrane risk-of-bias tool, and meta-analysis was performed using Revman 5.4 software. RESULTS: Of the 107 studies identified, six met the inclusion criteria. Three types of non-pharmacological treatments were identified: systematic desensitization (n = 2), hypnotherapy (n = 2), and yoga therapy (n = 2). Among them, systematic desensitization significantly improved anticipatory CINV as compared to that in the control group (nausea: risk ratio [RR] = 0.60, 95% confidence interval [CI] = 0.49-0.72, p < 0.00001; vomiting: RR = 0.54, 95% CI = 0.32-0.91, p = 0.02). However, heterogeneity in outcome measures precluded meta-analysis for hypnotherapy and yoga. Additionally, most selected studies had a high or unclear risk of bias, and adverse events were not consistently reported. CONCLUSIONS: Our findings suggest that systematic desensitization may effectively reduce anticipatory CINV. However, further research is warranted before implementation in clinical settings.
ABSTRACT
BACKGROUND: The Japan Society of Clinical Oncology Clinical Practice Guidelines for Antiemesis 2023 was extensively revised to reflect the latest advances in antineoplastic agents, antiemetics, and antineoplastic regimens. This update provides new evidence on the efficacy of antiemetic regimens. METHODS: Guided by the Minds Clinical Practice Guideline Development Manual of 2017, a rigorous approach was used to update the guidelines; a thorough literature search was conducted from January 1, 1990, to December 31, 2020. RESULTS: Comprehensive process resulted in the creation of 13 background questions (BQs), 12 clinical questions (CQs), and three future research questions (FQs). Moreover, the emetic risk classification was also updated. CONCLUSIONS: The primary goal of the present guidelines is to provide comprehensive information and facilitate informed decision-making, regarding antiemetic therapy, for both patients and healthcare providers.
ABSTRACT
PURPOSE: We prospectively compared the quality of images obtained by navigator setting on the left and right diaphragm on whole-heart coronary magnetic resonance angiography (WHCMRA). METHODS: In 10 healthy volunteers, we performed free-breathing, 3-dimensional segmented true fast imaging with steady-state precession (trueFISP) WHCMRA by setting the navigator on the left and right diaphragm in random order. For the left diaphragm, we set the navigator outside the scope of the heart to avoid the influence on coronary arteries. We compared image acquisition time and visible length of coronary arteries using paired t-test and subjective image quality on a 4-point scale (1, poor; 4, excellent) using Wilcoxon signed-rank test. RESULTS: Mean overall subjective image quality was significantly better in the left diaphragm than the right (3.3+/-0.7 versus 2.9+/-0.9, P=0.02). Mean overall visible length of the coronary arteries was significantly better in the left diaphragm than the right (115.4+/-31.1 vs. 112.6+/-29.9 mm, P=0.02). Mean acquisition time between the left and right diaphragm was not significantly different (15.6+/-5.0 versus 16.0+/-5.7 min, P=0.79). CONCLUSION: In this small group of healthy volunteers, navigator setting for WHCMRA was superior on the left diaphragm than the right; however, feasibility of the technique requires additional consideration in a larger group of actual patients.

Risk stratification among patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) has been made by clinical scoring. Recently, multiple-detector computed tomography (MDCT) appeared to provide noninvasive coronary angiography (CAG). To clarify the prognostic significance of MDCT, we aimed to evaluate the clinical utility of MDCT in the early management and in predicting the long-term prognosis of NSTE-ACS with low to intermediate risk. Among 84 consecutive patients with NSTEACS, risk stratification using a TIMI risk score was done. A total of 48 patients were categorized as low to intermediate risk. Multiple-detector CT was performed in 30 patients using 16-slice MDCT. MDCT detected coronary stenoses in 18 patients. Compared to invasive CAG, MDCT successfully depicted the coronary stenosis (P < 0.005), with sensitivity of 100% and specificity of 86%. The incidence of in-hospital major adverse clinical events (death, subsequent myocardial infarction, revascularization) was significantly higher in patients with a positive MDCT than in those with a negative MDCT test (44% vs 0%, P < 0.005). Moreover, a Kaplan-Meier analysis showed a significant difference in the event - free survival between MDCT positive and negative groups (33% vs 100%, respectively, P < 0.0001) during the mean follow-up period of 9.9 +/- 7.5 months. Sixteen-slice MDCT in conjunction with a TIMI risk score appeared to demonstrate prognostic significance in patients with NSTE-ACS.
