        A decrease in eating barnyard millet in Iwate prefecture: a literature review of Iwate no Hoken (hygiene in Iwate)

        Takahiro Mitsui 한국식품연구원 2020 Journal of Ethnic Foods Vol.7 No.-

        Although it is not used today, barnyard millet and foxtail millet were staples, especially for people living in the cold and mountainous areas in Japan. The Northern part of Iwate prefecture was the largest area for barnyard millet production, but its production had almost disappeared up to the late 1960s during the high economic growth period. The disused process and how people felt along with the mood during that time are not well examined. Articles in Iwate no Hoken (hygiene in Iwate), a local journal that was published by the Iwate prefecture National Health Insurance Organization from the mid-1950s to the late 1960s, were examined. This journal was mainly composed of a reader’s column or letters about every aspect of daily life, such as medicine, family problems, diet, education, culture, business, and readers’ autobiographies. Many articles indicated that people hid the fact that they ate millet. The rapid shift from millet to rice was accompanied by a change in their community from a selfsufficient society to a consuming society. The pleasure of eating white rice seemed to be fully suppressed by their financial problems regarding buying electric products, agricultural equipment, motorcycles, and food. Many laborers had to work outside of their hometown and the younger generation, especially girls, left their community. The editorial office concluded that the self-sufficient society had become a consuming society.

        Abundance of Veillonella spp. does not Reflect Salivary Nitrite Production after Nitrate Ingestion

        ( Takahiro Mitsui ),( Taichi Ishikawa ),( Ryo Harasawa ),( Minoru Sasaki ) 한국미생물생명공학회(구 한국산업미생물학회) 2020 한국미생물·생명공학회지 Vol.48 No.4

        Veillonella spp. have been reported to be the most prevalent nitrate-reducing bacterial species in the oral cavity. The purpose of this study was to examine the relationship between the abundance of Veillonella spp. and nitrite production after nitrate ingestion. Bacterial samples were obtained from the tongue surfaces of 50 university students. The predominant Veillonella spp., V. atypica, V. dispar, and V. rogosae were identified and enumerated using real-time polymerase chain reaction (qPCR). Salivary nitrate and nitrite were measured before and 30, 60, and 90 min after ingestion of 100 ml of beetroot juice. Increased nitrite concentrations were observed in all participants, with a mean increase of 0.61 (0.42-1.10) mM expressed as the median (interquartile range). Veillonella atypica was detected in 40 subjects (80%), V. dispar in 48 (96%), and V. rogosae in 48 (96%), at quantities ranging from 1.3 × 10<sup>2</sup> to 2.8 × 10<sup>7</sup> CFU/ml per subject. The strengths of the correlations of the log colony forming unit (CFU) values of V. atypica, V. dispar, V. rogosae, and the log CFU value of the three species together with the increase in nitrite levels were 0.091, 0.114, -0.228, and 0.060, respectively, none of which were significant (p > 0.05). Our results indicate that the abundance of Veillonella spp. is not related to salivary nitrite production after nitrate ingestion.

        Science electives in high school will improve nutrition knowledge but not enough to make accurate decisions

        Mitsui Takahiro,Yamamoto Susumu,Endo Morito 한국영양학회 2023 Nutrition Research and Practice Vol.17 No.4

        BACKGROUND/OBJECTIVES: Nutrition knowledge has been reported to have a weak positive effect on healthy eating behavior. This study aimed to determine if there was a difference in nutrition knowledge depending on the choice of science subject in high school and whether that affected the actual eating habits of college students in Japan. SUBJECTS/METHODS: The subjects were 514 college students, the majority first-year students, in 3 cities in Japan. A questionnaire sur vey was conducted on elective subjects in science in high school, diet (11 items), lifestyle (5 items), and nutrition knowledge (34 questions). The preliminar y sur vey was conducted on 47 students in the fall of 2019, and the full-scale sur vey was conducted in May–June and October–November 2021 at the end of lectures for the first-year students. RESULTS: The students in the high-score group (24–31 points, n = 180) had a higher intake of vegetables (odds ratio [OR], 1.78; 95% confidence inter val [CI], 1.12–2.82; P = 0.015) and breakfast (OR, 1.64; 95% CI, 1.03–2.60; P = 0.035), and a reduced intake of fast food (OR, 0.27; 95% CI, 0.14–0.51; P < 0.001) than those in the low-score group (6–19 points, n = 150). Only the biology and chemistr y students had significantly higher nutrition scores than the other groups (all: P < 0.001), but no significant difference was found between the other groups. Understanding nutrition learned in elementar y and junior high school is appropriate, while molecular structure, recommended amount, and food poisoning were insufficient. CONCLUSIONS: Knowledge of nutrition appears to have a positive effect on the actual eating habits of college students. Although biology and chemistr y in high school may help students understand the foundations of good nutrition, specialized food education may be required to make informed dietar y choices.

        Posterior decentering of the humeral head in patients with arthroscopic rotator cuff repair

        Hidehiro Nakamura,Masafumi Gotoh,Hirokazu Honda,Yasuhiro Mitsui,Hiroki Ohzono,Naoto Shiba,Shinichiro Kume,Takahiro Okawa 대한견주관절학회 2022 대한견주관절의학회지 Vol.25 No.1

        Background: In some patients with rotator cuff tear (RCT), the axial view of magnetic resonance imaging (MRI) shows subtle posterior decentering (PD) of the humeral head from the glenoid fossa. This is considered to result from a loss of centralization that is typically produced by rotator cuff function. There are few reports on PD in RCT despite the common occurrence of posterior subluxation in degenerative joint disease. In this study, we investigated the effect of PD in arthroscopic rotator cuff repair (ARCR). Methods: We conducted a retrospective study of consecutive patients who underwent ARCR at our institute and were followed-up for at least 1 year. PD was identified as a 2-mm posterior shift of the humeral head relative to the glenoid fossa in the axial MRI view preoperatively. The tear size and fatty degeneration (FD, Goutallier classification) were also evaluated using preoperative MRI. Retears were evaluated through MRI at 1 year postoperatively. Results: We included 135 shoulders in this study. Ten instances of PD (including seven retears) were observed preoperatively. Fifteen retears (three and 12 retears in the small/medium and large/massive tear groups, respectively) were observed postoperatively. PD was significantly correlated with tear size, FD, and retear occurrence (p<0.01 each). The odds ratio for PD in retears was 34.1, which was greater than that for tear size ≥3 cm and FD grade ≥3. Conclusions: We concluded that large tear size and FD contribute to the occurrence of PD. Furthermore, PD could be a predictor of retear after ARCR.
