ABSTRACT
Dry solid matter (rutin content: 51.6 mg/g; quercetin content: 72.2 mg/g) extracted from Tartary buckwheat boiled noodles using 70% methanol as the solvent was found to have α-glucosidase inhibitory activity. As for fractions fractionated by silica gel column chromatography, the fractions rich in quercetin and rutin showed remarkable α-glucosidase inhibitory activity. Tartary buckwheat boiled noodles used as samples in this study contained quercetin produced from rutin by the action of rutinase, suggesting that both rutin and quercetin contained were involved in the α-glucosidase inhibitory activity of the dry solid extract. Changes in postprandial blood glucose levels were compared for boiled noodles made from two types of buckwheat (i.e., Tartary buckwheat and common buckwheat), revealing that blood glucose elevation after eating Tartary buckwheat boiled noodles was suppressed. The blood glucose level 40 minutes after eating Tartary buckwheat boiled noodles was significantly low (p<0.05). It can be concluded that this might be caused by the α-glucosidase inhibitory activity of rutin (270.0 mg) and quercetin (330.5 mg), which correspond to a total amount of 935 mg of rutin equivalents, in the gastrointestinal tract. As a result, the digestion of carbohydrates contained in the samples consumed and their absorption by the intestine might be inhibited, resulting in the suppression of increases in blood glucose levels. The presence of a certain amount of quercetin was considered to be key to the suppression of blood glucose elevation. It is important to control rapid postprandial blood glucose increases to prevent diabetes from developing or becoming serious. This study suggests the potential for Tartary buckwheat boiled noodles to contribute to diabetes prevention.
ABSTRACT
This study aimed to clarify the resources required to relieve distress during palliative care delivery to cancer patients. Between April 2015 and March 2017, 1479 outpatients receiving chemotherapy for cancer were screened using the Japanese version of the Support Team Assessment Schedule (STAS-J). When the STAS-J result was 2 points and higher, the patient was considered positive for distress. A certified nurse or pharmacist performed STAS-J screening and, in cases where the patient exhibited distress, took steps to alleviate the problem themselves or consulted another resource. Distress was identified in 181 (12.2%) of the 1479 patients. These 181 patients needed 288 resources. The resources used to alleviate distress were categorized as follows: direct support by certified nurse or pharmacist (153), consultation with the attending physician (98) and other (37). The required resource included the following twelve professionals: attending physician, ophthalmologist, dermatologist, dentist, orthopedic surgeon, palliative care physician, certified nurse, certified pharmacist, medical social worker, clinical psychologist, volunteers for cancer patients, and palliative care team. The frequency of the intervention by the certified nurse or pharmacist (61, 39.9%) in directly alleviating psychiatric distress was significantly higher than by consultation with the attending physician (10, 10.2%) (p<0.0001). However, the frequency of consultation with the attending physician in alleviating physical distress (88, 89.8%) was significantly higher than that of the certified nurse or pharmacist (92, 60.1%) (p<0.0001). We conclude that the certified nurse or pharmacist is important for the delivery of palliative cancer care, because they can directly provide relief from psychiatric distress.
