    グミ科, ヒッポファエ属の沙棘 (サジー, 学名:Hippophae rhamnoides L., 英語名:Seabuckthorn) は, 生理活性物質を豊富に含む植物である. ニーヴァンス (株) はサジーを用いて滋養強壮剤を開発中であるが, その搾り粕も栄養を豊富に含むため有効な活用法を模索している. 本研究では, 離乳直後の黒毛和牛15頭 (雄 9 頭, 雌 6 頭) を用いて, 配合飼料へのサジー搾り粕添加給与による離乳ストレスならびに成長に関する影響を血中成分により調査した. 対照区 ( 5 頭, 体重:81.1±4.6kg), サジー搾り粕 5 %添加区 ( 5 頭, 85.4±9.3kg) および同10%添加区 ( 5 頭, 80.2±6.4kg) を設定し, 離乳時から 6 カ月間の体重と血液性状の変化を調べた. 頚静脈から採血後, 血清中総蛋白質 (Biuret 法), アルブミン (BCG 法), 中性脂肪 (酵素法), γ-GTP (JSCC 準拠法), 免疫に関わる IgA, IgG および IgM (ネフェロメトリー法) 含量を測定した. 離乳時体重を基準とした場合のその後の成長に伴う体重比は, 対照区に比べて, 5 %と10%添加区で有意 (P <0.05) に低かった. 総蛋白質, アルブミンおよび中性脂肪含量は, 実験期間を通して変動したが一定の傾向はなかった. γ-GTP 含量は対照区と10%添加区に比べて, 5 %添加区では離乳時から 1 カ月目まで高値を示した (P <0.05). IgA, IgG および IgM 含量に一定の傾向はなかった. 以上より, 配合飼料へのサジー搾り粕添加 (10%以内) は, 牛の健康及び成長に害を及ぼすことはなかったが, 牛の血液性状ならびに体重増加にも特別の効果は及ぼさなかった. しかし, 育成期において増体の低下に影響することが示唆され, 配合飼料としての利用は直接添加することを避け, 加工や栄養素の抽出操作などを行う必要があるものと考えられた.Seabuckthorn (Hippophae rhamnoides L.) is the plant which contained many nutrients, for vitamin. In this study, the effect of seabuckthorn lees (SL) which added in concentrate feed on the growth and blood parameter, in particular factors in relation to stress in the weaning period was investigated using Japanese black cattle (n=15). Control group (n=5, body weight: 81.1±4.6kg) , 5% SL group (n=5, 85.4±9.3kg) and 10 % SL group (n=5, 80.2±6.4kg) were set up. The changes of body weight and blood parameter from wean to six months cattle were investigated. Body weight in 5 % and 10 % SL group were lower (P<0.05) than that of control group. There were differences of serum total protein, albumen and triglyceride among group. Contents of γ-GTP in 5% group was higher (P<0.05) those of control and 10 % group from weaning to one month. The contents of IgA, IgG and IgM were not changed. Therefore growth and blood parameter in cattle were not affected by the addition to SL (within 10 %). However, body weight in cattle decreased for SL addition. For use of SL, future study needs to investigate the processing and extracting of SL

    Effects of pre‐operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study

    We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05-1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4-7 days or >= 8 days of 1.25 (1.04-1.48), p = 0.015 and 1.31 (1.11-1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care
