Abstract

BACKGROUND:ω-3 polyunsaturated fatty acids (n-3 PUFAs) are reported to have beneficial effect on bone mineral density. This study aimed to evaluate early changes of bone turnover biomarkers in very low-birth-weight (VLBW) neonates and the effect of 2 parenteral lipid emulsions (PLEs) with different PUFA composition. METHODS:This is a randomized double-blind study with parallel design. VLBW neonates (n = 66) receiving parenteral nutrition (PN)>70% of daily energy requirements for >14 days were assigned into 2 groups that were prescribed soybean oil-based (n = 35) and n-3-enriched PLE (n = 31), respectively. Osteoprotegerin (OPG), soluble receptor activator of nuclear factor-kB ligand (sRANKL), osteocalcin (OC), interleukin-6 (enzyme-linked immunoblot assay kits), Ca, and P plasma levels were assessed before PLE implementation (T1) and on day 20 of life (T2). RESULTS:In the total population, sRANKL and OC significantly increased, whereas OPG and the OPG/sRANKL ratio decreased from T1 to T2. Within each group, T1-to-T2 changes of OC were significant in both groups, whereas those of OPG/sRANKL were significant only in the soybean-based group. Multiple regressions showed an independent effect of group allocation on OPG change. Significant associations were observed between PN duration and sRANKL change (negatively), n-6/n-3 and OC changes (positively), and OPG and sRANKL changes (positively). CONCLUSIONS:A high bone-turnover rate in VLBW neonates with predominance of bone resorption is confirmed. The lower rate of OPG/sRANKL reduction in the n-3-enriched PLE group indicates that n-3 PUFA-enriched PLEs may help to attenuate early bone loss in VLBW neonates.

摘要

背景: 据报道 ω-3 多不饱和脂肪酸 (n-3 PUFAs) 对骨密度有有益作用。本研究旨在评估极低出生体重 (VLBW) 新生儿骨转换生物标志物的早期变化以及 2 种不同 PUFA 成分的肠外脂肪乳剂 (PLEs) 的影响。 方法: 本研究为平行设计的随机双盲研究。VLBW 新生儿 (n = 66) 接受肠外营养 (PN)> 70% 每日能量需求> 14 天,被分配到 2 组,处方大豆油为基础 (n = 35) 和 n-3-enriched PLE (n = 31),分别。骨保护素 (OPG),可溶性核因子-kB 受体活化因子配体 (sRANKL),骨钙素 (OC) interleukin-6 (酶联免疫印迹测定试剂盒),Ca, 在 PLE 实施前 (T1) 和生命第 20 天 (T2) 评估 P 血浆水平。 结果: 在总人群中,sRANKL 和 OC 显著升高,而 OPG 和 OPG/sRANKL 比值从 T1 下降到 t2。在每组中,OC 的 T1-to-T2 变化在两组中均显著,而 OPG/sRANKL 的变化仅在基于大豆的组中显著。多重回归显示组分配对 OPG 变化的独立影响。观察到 PN 持续时间与 sRANKL 变化 (负) 、 n-6/n-3 和 OC 变化 (正) 以及 OPG 和 sRANKL 变化 (正) 之间存在显著相关性。 结论: 以骨吸收为主的 VLBW 新生儿骨转换率较高。N-3-enriched PLE 组 OPG/sRANKL 降低率较低,表明 n-3 PUFA 富集的 PLEs 可能有助于减轻 VLBW 新生儿早期骨丢失。

METHODS:OBJECTIVES:To evaluate the effect of esophageal stimulation on nutritional adequacy in critically ill patients at risk for enteral feeding intolerance. DESIGN:A multicenter randomized sham-controlled clinical trial. SETTING:Twelve ICUs in Canada. PATIENTS:We included mechanically ventilated ICU patients who were given moderate-to-high doses of opioids and expected to remain alive and ventilated for an additional 48 hours and who were receiving enteral nutrition or expected to start imminently. INTERVENTIONS:Patients were randomly assigned 1:1 to esophageal stimulation via an esophageal stimulating catheter (E-Motion Tube; E-Motion Medical, Tel Aviv, Israel) or sham treatment. All patients were fed via these catheters using a standardized feeding protocol. MEASUREMENTS AND MAIN RESULTS:The co-primary outcomes were proportion of caloric and protein prescription received enterally over the initial 7 days following randomization. Among 159 patients randomized, the modified intention-to-treat analysis included 155 patients: 73 patients in the active treatment group and 82 in the sham treatment group. Over the 7-day study period, the percent of prescribed caloric intake (± SE) received by the enteral route was 64% ± 2 in the active group and 65% ± 2 in sham patients for calories (difference, -1; 95% CI, -8 to 6; p = 0.74). For protein, it was 57% ± 3 in the active group and 60% ± 3 in the sham group (difference, -3; 95% CI, -10 to 3; p = 0.30). Compared to the sham group, there were more serious adverse events reported in the active treatment group (13 vs 6; p = 0.053). Clinically important arrhythmias were detected by Holter monitoring in 36 out of 70 (51%) in the active group versus 22 out of 76 (29%) in the sham group (p = 0.006). CONCLUSIONS:Esophageal stimulation via a special feeding catheter did not improve nutritional adequacy and was associated with increase risk of harm in critically ill patients.

METHODS:RATIONALE:The long-term effects of delivering approximately 100% of recommended calorie intake via the enteral route during critical illness compared to a lesser amount of calories are unknown. OBJECTIVES:Our hypotheses were that achieving approximately 100% of recommended calorie intake during critical illness would increase quality of life scores, return to work and key life activities and reduce death and disability six months later. METHODS:We conducted a multicenter, blinded, parallel group, randomized clinical trial, with 3957 mechanically ventilated critically ill adults allocated to energy-dense (1.5 kcal/ml) or routine (1.0 kcal/ml) enteral nutrition. MEASUREMENTS AND MAIN RESULTS:Participants assigned energy-dense nutrition received more calories (% recommended energy intake, mean (SD) (energy-dense: 103% (28) vs. usual: 69% (18)). Mortality at day-180 was similar (560/1895 (29.6%) vs. 539/1920 (28.1%); relative risk 1.05 (95%CI, 0.95 to 1.16)). At a median [IQR] of 185 [182, 193] days after randomization, 2492 survivors were surveyed and reported similar quality of life (EuroQol five dimensions five-level quality of life questionnaire visual analogue scale, median [IQR]: 75 [60-85]; group difference: 0 (95%CI, 0 to 0)). Similar numbers of participants returned to work with no difference in hours worked or effectiveness at work (n=818). There was no observed difference in disability (n=1208) or participation in key life activities (n=705). CONCLUSIONS:The delivery of approximately 100% compared to 70% of recommended calorie intake during critical illness does not improve quality of life, or functional outcomes, or increase the number of survivors six months later.

METHODS:BACKGROUND:Provision of enteral nutrition with jejunal feeding in upper gastrointestinal obstruction is highly recommended. Access to jejunum can be obtained surgically, percutaneously, or endoscopically. Our institution routinely and preferentially utilizes a silicone nasojejunal tube that is inserted past the obstruction endoscopically. We use a custom dual channel tube that allows feeding at the distal tip and another channel 40 cm from the tip that enables decompression proximally. This is a report of our experience with this custom nasojejunal tube. METHODS:This is a prospective observational study of 201 patients who underwent endoscopic nasojejunal wire-guided feeding tube insertions for obstruction of either the esophagus or the stomach including both benign and malignant pathologies between January 2015 to June 2018 in Hospital Sungai Buloh and Hospital Sultanah Aminah, Malaysia. The indications for tube insertion, insertion technique, and tube-related problems were described. RESULTS:The nasojejunal tube was used to establish enteral feeding in patients with obstructing tumors of the distal esophagus in 65 patients (32.3%) and gastric outlet obstruction in 72 patients (35.8%). There were 54 patients (26.9%) who required reinsertion. The most common reason for reinsertion was unintentional dislodgement, where 32 patients (15.9%) followed by tube blockage 20 patients (10.0%). Using our method of advancement under direct vision, we had only 2 cases of malposition due to severely deformed anatomy. We had no incidence of aspiration in this group of patients and overall, the patients tolerated the tube well. CONCLUSIONS:The novel nasojejunal feeding tube with gastric decompression function is a safe and effective method of delivery of enteral nutrition in patients with upper gastrointestinal obstruction. These tubes if inserted properly are well tolerated with almost no risk of malposition and are tolerated well even for prolonged periods of time until definitive surgery could be performed.
