Effects of Postprandial Body Position on Gastrointestinal Motility, the Autonomic Nervous System and Subjective Comfort

We examined postprandial body positions’ effects on gastrointestinal motility, the autonomic nervous system and subjective comfort, i.e., whether lowering the head after a meal is beneficial for gastrointestinal motility and the prevention of pressure ulcer. We examined 10 healthy subjects and compared 3 body positions: (1) Seated upright. (2) Lying on a bed with the head at 60° and knees up by 20° (60° position). (3) Identical to (2) until post-meal; the head was then lowered to 30° (60°-30° position). Gastrointestinal motility was assessed as gastrointestinal sounds measured by sound-editing software. Digital plethysmography assessed autonomic nerve function as heart rate variability. The pressure ulcer risk was estimated as subjective comfort/discomfort using a visual analog scale. Gastrointestinal sounds increased post-meal. The 60°-30° position showed the highest number of sounds and longest cumulative sound duration. Post-meal, sympathetic activation was suggested in the 60° position, whereas vagal activity was relatively preserved in the 60°-30° position. The 60°-30° position was the most comfortable, and the 60° position was least comfortable. Lowering the head after a meal is beneficial to augment gastrointestinal motility and decrease the pressure ulcer risk. The 60° head-up position increases the pressure ulcer risk

学生の衛生管理習得度に及ぼすオリジナルビデオ教材と大量調理実習の実施回数の効果の検討

本研究では，管理栄養士専攻学生の大量調理実習において，クラウド型授業支援システム（manaba course）を活用してビデオ教材の動画を配信した受講生（ビデオ教材-manaba配信群）とビデオ教材を導入していない受講生（ビデオ教材なし群）の衛生管理習得度を比較した。大量調理7回目のビデオ教材-manaba配信群（81人）とビデオ教材なし群（97人）の習得度を比較したところ，ビデオ教材-manaba配信群がビデオ教材なし群よりも「指導できる」・「一人で実践できる」と回答した者の割合が高かった項目は「水質検査」のみであった。一方，ビデオ教材が実習に役立つと回答した者は98%であった。さらに，衛生管理習得度に対する大量調理の実施回数の効果を検討した。大量調理を伴う実習が0，2，4，7回目（大量調理0回，2回，4回，7回）の際に習得度を調査した。大量調理7回目で「指導できる」・「一人で実践できる」と回答した学生が過半数を超えたのは3項目であり，衛生管理習得度が高い項目は実習での作業経験者の割合も高かった。これらの結果より，大量調理実習における衛生管理習得度の向上には，学生が実際に衛生管理に関する作業を経験することが重要であると考えられた。また，ビデオ教材の活用は，学生自らの経験には及ばないが，衛生管理に関する知識を補い，実習の予習や復習に役立つ可能性が高いと考えられた。研究ノー

Ovarian abscess caused by Helicobacter cinaedi in a patient with endometriosis

Helicobacter cinaedi is a rarely encountered pathogen that easily induces bacteremia. Various foci of H. cinaedi infection have been reported; however, no case of adnexal abscess caused by H. cinaedi has been reported in the English literature. We herein report a case of ovarian abscess caused by H. cinaedi.A 38-year-old nulligravid Japanese woman was admitted to our hospital with an adnexal abscess. Clinical findings included fever, leukocytosis, and elevated C-reactive protein. Laparoscopic right partial oophorectomy with abdominal lavage was performed. H. cinaedi was isolated from cultures of blood and ovarian abscess fluid after surgery. Intravenous ampicillin/sulbactam was administered for 2 weeks, followed by oral amoxicillin for an additional 2 weeks. The postoperative course was uneventful and clinical findings improved. There was no evidence of relapse. H. cinaedi can cause ovarian abscess and is likely an under-recognized pathogen. Keywords: Helicobacter, Laparoscopy, Ovary, Abscess, Endometriosi
