Purpose/Objectives: To evaluate the effect of ginger as an antiemetic modality for the control of chemotherapy-induced nausea and vomiting (CINV).
Data Sources: Databases searched included MEDLINE® (PubMed), Embase, CINAHL®, Cochrane Central Register of Controlled Trials, Korean Studies Information Service System, Research Information Sharing Service by the Korean Education and Research Information Service, and Dissertation Central.
Data Synthesis: A systematic review was conducted of five randomized, controlled trials involving 872 patients with cancer. Ginger was compared with placebo or metoclopramide. The participant characteristics, chemotherapy regimen and antiemetic control, ginger preparation and protocol, measurements, results of the studies, adherence to the treatment protocol, and side effects were reviewed systematically. The incidence and severity of acute and delayed CINV were subject to meta-analysis. The incidence of acute nausea (p = 0.67), incidence of acute vomiting (p = 0.37), and severity of acute nausea (p = 0.12) did not differ significantly between the ginger and control groups.
Conclusions: Current evidence does not support the use of ginger for the control of CINV. Ginger did not contribute to control of the incidence of acute nausea and vomiting or of the severity of acute nausea.
Implications for Nursing: Ginger has long been regarded as a traditional antiemetic modality, but its effectiveness remains to be established. The findings of this study could be incorporated into clinical guidelines, such as the Oncology Nursing Society's Putting Evidence Into Practice resources. Current evidence supports the need for more methodologically rigorous studies in this area.
Knowledge Translation: Although ginger is known as a traditional antiemetic, current evidence does not support the effect of ginger in CINV control. The findings of this study inform healthcare providers that its effectiveness remains to be established from methodologically rigorous future trials.

    ABSTRACT: In healthy adults and children in developed countries, most foodborne and water-borne infections are short-lived and resolve without specific treatment. In developing areas, these infections may produce acute mortality and chronic morbidity caused by developmental impairment. Immune-compromised hosts are at increased risk of life-threatening complications. This article reviews recommendations for the treatment of the most common and important foodborne illnesses, focusing on those caused by infections or toxins of microbial origin. The cornerstone of life-saving treatment remains oral rehydration therapy, although the use of other supportive measures as well as antibiotics for certain infections is also recommended.

    ABSTRACT: Nausea and vomiting are very common symptoms in cancer both treatment and non-treatment related. Many complications of advanced cancer such as gastroparesis, bowel and outlet obstructions, and brain tumors may have nausea and vomiting or either symptom alone. In a non-obstructed situation, nausea may be more difficult to manage and is more objectionable to patients. There is little research on management of these symptoms except the literature on chemotherapy induced nausea where guidelines exist. This article will review the etiologies of nausea and vomiting in advanced cancer and the medications which have been used to treat them. An etiology based protocol to approach the symptom is outlined.

    ABSTRACT: Nausea and vomiting are common and unpleasant complications in pregnancy. Although many alternative therapists support the use of ginger for nausea and vomiting of pregnancy, there is currently insufficient clinical evidence to support its use in this condition. The present study was performed to assess the effectiveness of ginger in the treatment of nausea and vomiting in pregnancy. This seven-day clinical trial was performed on 120 eligible pregnant women with symptoms of mild to moderate nausea and vomiting before 16 weeks gestation. They were divided into; ginger, placebo and control groups, by block randomization. Women were asked to record their nausea and vomiting for three days, and then participants received either ginger capsules, or a placebo for four days. No intervention was done with the control group. Data measure was self-recorded symptoms according to the Rhodes Index. Data were analyzed by ANOVA, ANCOVA, Kruskal-Wallis, Chi-square, and Fisher's exact test, for the quantitative and qualitative variables. There were no statistical differences in the baseline demographics between the three groups apart from age of marriage and wanted or unwanted pregnancy. An ANCOVA test (covariance test) showed significant differences in mean scores after the intervention in the three groups (P < 0.001). Ginger was effective for the relief of mild to moderate nausea and vomiting in pregnant women at less than 16 weeks gestation.
