Adherence to COVID-19 Nutrition Guidelines Is Associated with Better Nutritional Management Behaviors of Hospitalized COVID-19 Patients

Good nutritional support is crucial for the immune system to fight against coronavirus disease 2019 (COVID-19). However, in the context of a pandemic with a highly transmissible coronavirus, implementation of nutrition practice may be difficult. A multicenter electronic survey involving 62 dieticians was conducted, in order to understand barriers associated with dieticians’ adherence to nutrition guidelines for hospitalized COVID-19 patients in Indonesia. 69% of dieticians felt under stress when performing nutrition care, and 90% took supplements to boost their own immunity against the coronavirus. The concerns related to clinical practice included a lack of clear guidelines (74%), a lack of access to medical records (55%), inadequate experience or knowledge (48%), and a lack of self-efficacy/confidence (29%) in performing nutritional care. Half (52%) of the dieticians had performed nutrition education/counseling, 47% had monitored a patient’s body weight, and 76% had monitored a patient’s dietary intake. An adjusted linear regression showed that guideline adherence independently predicted the dieticians’ nutrition care behaviors of nutrition counselling (ß: 0.24 (0.002, 0.08); p = 0.04), and monitoring of body weight (ß: 0.43 (0.04, 0.11); p = 0.001) and dietary intake (ß: 0.47(0.03, 0.10); p = 0.001) of COVID-19 patients. Overall, adherence to COVID-19 nutrition guidelines is associated with better nutritional management behaviors in hospitalized COVID-19 patients.

Immunogenicity,safety and reactogenicity of ROTAVAC® in healthy infants aged 6–8 weeks in Vietnam

BackgroundROTAVAC® is derived from human 116E rotavirus (RV) neonatal strain. In this study, we evaluated the immunogenicity, safety and reactogenicity of ROTAVAC® in Vietnam.MethodWe conducted a phase IV clinical trial in healthy infants aged 6–8 weeks using the complete regimen of ROTAVAC® with three doses. Serum anti-RV IgA was measured by enzyme-linked immunosorbent assay to assess the geometric mean concentration in infants who received the complete regimen of the vaccine.ResultsA total of 360 participants were enrolled in this clinical trial. The mean age ± standard deviation at enrollment was 6.9 ± 0.6 weeks. The anti-RV IgA titer was 4.01 ± 3.74 mg/ml pre-vaccination and substantially increased to 29.27 ± 80.64 mg/ml post-vaccination. The value of logIgA significantly increased (p = 0.003) from 0.28 ± 0.79 to 1.03 ± 0.54. The proportion of participants with equal to and greater than 3-fold and 4-fold shifts in pre- to post-vaccination antibody titer (IgA) were 55.4% and 48.3%, respectively. No adverse events or serious adverse events were recorded immediately within 30 min after the administration of each dose. The most common adverse events within 14 days after each visit were fever, unusual crying and irritability. Other adverse events occurred at a low rate, and no case of intussusception was noted.ConclusionsThe complete regimen of ROTAVAC® demonstrated an immunological response with clinically acceptable safety profile. Post-completion of this study, ROTAVAC® is now a WHO-prequalified vaccine and available in Vietnam.     

体质指数正常人群中的代谢综合征患病情况

目的 了解体质指数（BMI）正常人群多代谢异常与代谢综合征（MS）的患病情况。方法 选取2016年1月—2017年12月健康体检人群为研究对象,以2004年中华医学会糖尿病学分会制订的MS诊断标准,符合纳入标准的正常BMI对象共5 781名（男3 069名,女2 712名）。根据BMI的四分位数将调查对象分成Q1～Q4组计算性别、年龄别MS的患病率。结果 5 781名对象的MS患病率为12.71％（男性9.22％,女性16.67％,χ2 = 71.92,P＜0.001）。专业技术人员的MS患病率较其它职业人群显著增高（χ2 = 19.76,P = 0.001）,低学历人群的MS患病率较高学历人群显著增高（χ2 = 10.79,P = 0.005）。男性随BMI升高（Q1～Q4）MS患病率由3.21％增至17.54％（χ2 = 87.11,P＜0.001）;女性（Q1～Q4）MS患病率由7.32％增至29.78％（χ2 = 147.66,P＜0.001）。男性各个BMI组MS患病率均低于女性（Q1:3.21% vs 7.32%,χ2 = 10.31,P＜0.001;Q2:6.35% vs 10.26%,χ2 = 8.64, P＜0.001;Q3:9.72% vs 19.27%,χ2 = 27.39, P＜0.001;Q4:17.54% vs 29.79%,χ2 = 28.11,P＜0.001）。男性随年龄升高（≤40岁～≥60岁）MS患病率由3.43％增至13.15％（χ2 = 67.09,P＜0.001）、女性（≤40岁～≥60岁）MS患病率由10.72％增至24.25％（χ2 = 54.43,P＜0.001）;随BMI升高（Q1～Q4）,伴有MS组分异常的患病率由28.51％增至40.56％（χ2 = 77.39,P＜0.001）。结论 BMI正常人群仍有一定多代谢异常和MS患病率,要注意BMI正常人群的代谢性健康风险管理。     

桂花提取物Osthin的免疫功能研究

目的 通过对桂花提取物Osthin的免疫功能进行研究,促进其在食品、保健品等领域的开发。方法 将SPF级雌性昆明小鼠160只随机分为对照组和低、中、高剂量组（50、150、450 mg/kg bw）。灌胃Osthin 4周,分别进行脏器/体重比值测定、抗体生成细胞实验、脾淋巴细胞转化实验、迟发型变态反应实验、小鼠碳廓清实验、血清溶血素测定和脾细胞的Treg/Th17比值分析。结果 与植物油对照组相比,一定剂量的桂花提取物Osthin对小鼠的胸腺系数（F = 8.440,P＜0.01）和脾脏系数（F = 4.710,P＜0.01）有增强作用;对脾淋巴细胞增殖能力有促进作用（F = 5.991,P＜0.01）以及可增强迟发型变态反应（F = 4.213,P＜0.05）;提高小鼠的吞噬指数a（F = 3.901,P＜0.05）;使抗体生成细胞数增加（F = 5.192,P＜0.01）。同时,随着桂花提取物Osthin浓度的升高,小鼠脾细胞的Th17细胞比例下降（F = 5.203,P＜0.05）、Treg细胞比例上升（F = 7.369,P＜0.05）,Treg/Th17比值也随之增大（F = 8.377,P＜0.01）。结论 桂花提取物Osthin具有较好的免疫增强作用,可能通过影响Treg/Th17的平衡调节细胞免疫功能。
