Self-Acupressure for Symptom Management in Cancer Patients: A Systematic Review.

CONTEXT: Acupressure is a popular nonpharmacological intervention that is increasingly proven to effectively alleviate symptoms in patients with cancer. However, the effects of self-acupressure on cancer symptom management are less clear. OBJECTIVES: This systematic review is the first to summarize the current experimental evidence on self-acupressure for symptom management in cancer patients. METHODS: Eight electronic databases were searched for experimental studies that examined self-acupressure for cancer patients with symptoms and published in peer-reviewed English or Chinese journals. The methodological quality of the included studies was evaluated using the revised Cochrane risk-of-bias assessment tool and the JBI critical appraisal checklist for quasi-experimental studies. Data were extracted as predefined and synthesized narratively. The Template for Intervention Description and Replication checklist was used to report the intervention characteristics. RESULTS: A total of 11 studies were included in this study, six as feasibility or pilot trials. The methodological quality of included studies was suboptimal. Substantial heterogeneity was observed in acupressure training, acupoint selection, intervention duration, dosage, and timing. Self-acupressure was only associated with reduced nausea and vomiting (P = 0.006 and P = 0.001). CONCLUSION: The limited evidence from this review precludes the definitive conclusions on intervention effectiveness for cancer symptoms. Future research should consider developing the standard protocol for intervention delivery, improving the methodology of self-acupressure trials, and conducting large-scale research to advance the science of self-acupressure for cancer symptom management.

Association between Auricular Signals and the Risk Factors of Metabolic Syndrome.

Objective: This study aims to determine the association between auricular signals and the risk factors of metabolic syndrome (MS). Methods: A case-control study with an equal number of cases and controls matched by age group and gender was conducted. A total of 204 participants were recruited. Patients were verified as having MS based on the International Diabetes Federation (IDF) criteria. Auricular assessment was conducted in the following sequence: visual inspection, electrical skin resistance test (ESRT), and pressure pain test (PPT). Results: MS+ patients tend to have much more oily auricle complexion than the controls. The 'endocrine' (right) of the participants with MS indicated a significantly higher electrical conductivity compared to that of the controls. The MS group participants experienced significant tenderness on the 'heart' and 'endocrine' acupoints. A number of auricular signals were also associated with the risk factors of MS, including age, gender, smoking status, family history of diabetes, and comorbid illnesses. Both the 'heart' and 'endocrine' acupoints showed the highest sensitivity to tenderness (60.8%), followed by the 'endocrine' (59.8%) and 'pancreas and gallbladder' (55.9%). Conclusions: The results of this study suggest that electrical conductivity and tenderness of a number of auricular points, including the 'heart', 'pancreas and gall bladder', and 'endocrine', are associated with MS and its risk factors. Further investigations with a larger sample size could be conducted to verify the value of these auricular signals on MS risk prediction so that this method can be used as an early screening method for the population with a high MS risk.
