Studies examining the effect of artichoke on liver enzymes have reported inconsistent results. This systematic review and meta-analysis aimed to assess the effects of artichoke administration on the liver enzymes. PubMed, Embase, the Cochrane Library, and Scopus databases were searched for articles published up to January 2022. Standardized mean difference (Hedges' g) were analyzed using a random-effects model. Heterogeneity, publication bias, and sensitivity analysis were assessed for the liver enzymes. Pooled analysis of seven randomized controlled trials (RCTs) suggested that the artichoke administration has an effect on both alanine aminotransferase (ALT) (Hedges' g, -1.08; 95% confidence interval [CI], -1.76 to -0.40; p = 0.002), and aspartate aminotransferase (AST) (Hedges' g, -1.02; 95% CI, -1.76 to -0.28; p = 0.007). Greater effects on ALT were detected in trials that lasted ≤8 weeks. Also, greater effects on AST were detected in trials using > 500 mg artichoke. Overall, this meta-analysis demonstrated artichoke supplementation decreased ALT and AST.

Numerous clinical trials have examined the beneficial effects of Juglans regia leaf extract (JRLE) in patients with type 2 diabetes mellitus (T2DM); however, the results of these studies are inconsistent. Therefore, we conducted the current systematic review and meta-analysis to evaluate the effect of JRLE on glycemic control and lipid profile in T2DM patients. We searched online databases including PubMed, Scopus, EMBASE, and Web of Science for randomized controlled clinical trials that examined the effect of JRLE on glycemic and lipid indices in T2DM patients. Data were pooled using both fixed and random-effect models and weighted mean difference (WMD) was considered as the overall effect size. Of the total records, 4 eligible studies, with a total sample size of 195 subjects, were included. The meta-analysis revealed that JRLE supplementation significantly reduces fasting blood glucose (WMD, −18.04; 95% confidence interval [CI], −32.88 mg/dL, −3.21 mg/dL; p = 0.017) and significantly increases fasting insulin level (WMD, 1.93; 95% CI, 0.40 U/L, 3.45 U/L; p = 0.014). Although the overall effect of JRLE supplementation on hemoglobin A1c was not significant, a significant reduction was seen in studies with an intervention duration of > 8 weeks (WMD, −0.64; 95% CI, −1.16%, −0.11%; p = 0.018). Moreover, we also found no significant change in lipid parameters. Our findings revealed a beneficial effect of JRLE supplementation on glycemic indices in T2DM patients, but no significant improvement was found for lipid profile parameters.
许多临床试验已经检验了核桃叶提取物（JRLE）对2型糖尿病（T2DM）患者的有益作用；然而，这些研究的结果并不一致。因此，我们进行了当前的系统综述和荟萃分析，以评估JRLE对T2DM患者血糖控制和脂质状况的影响。我们在PubMed、Scopus、EMBASE和Web of Science等在线数据库中搜索了随机对照临床试验，这些试验检查了JRLE对T2DM患者血糖和脂质指数的影响。使用固定和随机效应模型合并数据，并将加权平均差（WMD）视为总体效应大小。在总记录中，包括4项符合条件的研究，总样本量为195名受试者。荟萃分析显示，补充JRLE可显著降低空腹血糖（WMD，−18.04；95%置信区间[CI]，−32.88 mg/dL，−3.21 mg/dL；p=0.017），并显著提高空腹胰岛素水平（WMD、1.93；95%置信度，0.40 U/L，3.45 U/L；p=0.014）。尽管补充JRLE对血红蛋白A1c的总体影响并不显著，在干预持续时间>8周的研究中发现显著减少（WMD，−0.64；95%CI，−1.16%，−0.11%；p=0.018）。此外，我们还发现脂质参数没有显著变化。我们的研究结果显示，补充JRLE对T2DM患者的血糖指数有有益影响，但对血脂谱参数没有发现显著改善。

This study sought to investigate the effects of the enhanced recovery after surgery (ERAS) program on postoperative recovery and nutritional status in patients with colorectal cancer undergoing laparoscopic surgery. A total of 37 patients were included: 19 in the experimental group and 18 in the control group. The experimental group was supplemented with carbohydrate drinks before and after surgery, and the control group was maintained with fasting and water intake in the traditional method. Both care management and nutrition education were implemented for both groups. Patients were evaluated for physical condition, clinical indicators, blood tests, pain, length of stay, nutritional status, and nutrient intake. Use of the ERAS program for the experimental group resulted in shorter length of stay (p = 0.006), less pain (p < 0.001), and a lower rate of malnutrition (p = 0.014) compared with controls. In conclusion, carbohydrate drinks provide great advantages by reducing discomfort, such as pain or thirst, during fasting in patients after colon cancer surgery, helping patients to eat comfortably and actively, minimizing insulin resistance, maintaining nitrogen balance, and reducing infection and anastomosis leakage. For use of ERAS as a standardized program, repeated and expanded research is needed, and a Korean-style ERAS should be prepared by using this approach for various diseases.

Musculoskeletal pains (MPs), defined as persistent or recurrent pain, is a complex health problem. High overall calorie and fat intake have been related to obesity and MPs. Dietary energy density (DED), defined as energy content of food and beverages (in kcal) per unit total weight, has been associated with chronic muscle, cartilage, bone damage and pain. Thus, the purpose of this study is to investigate the association between DED and MPs in adult men and women. A total of 175 men and women (> 18 years) with MP participated in the study. A validated short form physical activity (PA) questionnaire, demographic, and McGill Pain Questionnaire were used. Anthropometric measurements were evaluated via standard protocols. Furthermore, a seven-day 24-hour recall of diet was used to determine the dietary intake. Total DED was calculated and divided into quartiles. Linear regression was used to discern the association between DED and MPs in adults. Participants assigned in the highest category of DED were characterized by lower intake of potassium, magnesium, vitamin C, folate, and fiber. However, results showed displayed higher intake of sodium, vitamin E, vitamin B3, fat, protein, cholesterol, saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids (p < 0.001). Finally, after adjustment for confounders such as age, gender, PA, body mass index, waist circumference, education, job, marital status, history of some chronic diseases and vitamin C supplementation, a significant positive association was detected between DED and pain intensity. There was no significant association between DED and pain frequency in all models.

Patients with short bowel syndrome (SBS) have a high risk of developing parenteral nutrition (PN)-associated complications. Therefore, diet or enteral nutrition and PN should be modified to limit such complications. N balance analysis is a method of calculating the amount of protein required to achieve N equilibrium in the body based on intake and excretion. It is important to reduce dependence on PN and achieve the recommended range of N balance 2–4 g with an appropriate diet. We report a recent experience with nutrition modification using N balance analysis and suggest it as a useful method to reduce dependence on PN in nutrition management of SBS patients and in continuing active intestinal rehabilitation.

As the proportion of the elderly population increases rapidly, interest in musculoskeletal health is also emerging. Here, we investigated how antioxidant vitamin intake and musculoskeletal health are related. Adults aged 50 to 80 years with a body mass index (BMI) of 18.5 to 27.0 kg/m2 were included. Bone mineral density (BMD), lean mass (LM), appendicular skeletal muscle mass index (ASMI) were measured using dual-energy X-ray absorptiometry (DXA), and the grip strength and knee extension using hand dynamometer. Nutrient intakes were measured using a 24-hour recall questionnaire. A total of 153 adults (44 men and 109 women) participated in this study. A partial correlation analysis showed a significant positive relationship between vitamin E and BMD and between vitamin C and LM/Height. Participants were classified into three groups according to whether their vitamin E and C intake met the recommended intake for Dietary Reference Intakes for Koreans (KDRIs). The prevalence of having low T-score (< −1.0) and low ASMI (< 7.0 for men and < 5.4 for women) was 51.3% and 15.4% in the group with vitamins C and E intakes below KDRIs. After adjusting for sex, smoking status and energy, protein, vitamin D, and calcium intake, the group with vitamins C and E both below the KDRIs displayed a significantly lower BMD at all test sites and LM/Height compared with vitamin C and/or E intake above the KDRIs groups. We conclude that sufficient intake of vitamin E and C is important for maintaining BMD and lean mass in Korean adults over 50 years of age.

Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine. Oxidative stress and inflammation play a major role in IBS. Considering the antioxidant properties of ellagic acid (EA), this study was designed to evaluate the effect of EA on oxidative stress index, inflammatory markers, and quality of life in patients with IBS. This research was conducted as a randomized, double-blind, placebo-controlled clinical trial; 44 patients with IBS were recruited. Patients who met the inclusion criteria were randomly allocated to consume a capsule containing 180 mg of EA per day (n = 22) or a placebo (n = 22) for 8 weeks. Serum levels of total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), and interleukin-6 (IL-6) were measured at the beginning and the end of the study. Also, quality of life was assessed using a self-report questionnaire for IBS patients (IBS-QOL). At the end of the study, we saw a significant decrease and increase in the MDA and TAC in the intervention group, respectively (p < 0.05). Also, EA consumption reduced CRP and IL-6 levels, and these changes were significant in comparison with placebo group changes (p < 0.05). The overall score of IBS-QOL significantly decreased, and quality of life was increased (p < 0.05), but there were no significant changes in the placebo group. According to these findings, receiving polyphenols, such as EA, may help maintain intestinal health by modulating inflammation and oxidative stress and ultimately improving the quality of life in IBS patients.

The aim of this systematic review and meta-analysis was to summarize all the existing randomized controlled trials (RCTs) evidence and to evaluate the effects of magnesium supplementation on serum magnesium, calcium and urinary magnesium concentrations in patients with type 2 diabetes compared with the control. Two independent authors systematically searched online databases including Embase, Scopus, PubMed, and Web of Science from inception until 30th January 2022. RCTs complying with the inclusion criteria were included in this meta-analysis. The heterogeneity among the included studies was assessed using Cochrane’s Q test and I-square (I2) statistic. Data were pooled using a random-effects model and weighted mean difference (WMD) was considered as the overall effect size. Sixteen trials were included in this meta-analysis. Serum magnesium (mean difference, 0.15 mg/dL; 95% confidence interval [CI], 0.06 to 0.23; p = 0.001) and urinary magnesium (WMD, 1.99 mg/dL; 95% CI, 0.36 to 3.62; p = 0.017) concentrations were significantly increased after magnesium supplementation when compared with the control group. However, magnesium supplementation did not have any significant effect on serum calcium (WMD, −0.09 mg/dL; 95% CI, −0.27 to 0.08; p = 0.294) level when compared with the control group. This meta-analysis demonstrated that magnesium supplementation significantly increased Serum magnesium levels which may have played an indirect role in improved clinical symptoms in patients with type 2 diabetes.

Two independent authors systematically searched online databases including Embase, Scopus, PubMed, and Web of Science from inception until 30th January 2022. RCTs complying with the inclusion criteria were included in this meta-analysis. The heterogeneity among the included studies was assessed using Cochrane’s Q test and I-square (I2) statistic. Data were pooled using a random-effects model and weighted mean difference (WMD) was considered as the overall effect size. Sixteen trials were included in this meta-analysis. Serum magnesium (mean difference, 0.15 mg/dL; 95% confidence interval [CI], 0.06 to 0.23; p = 0.001) and urinary magnesium (WMD, 1.99 mg/dL; 95% CI, 0.36 to 3.62; p = 0.017) concentrations were significantly increased after magnesium supplementation when compared with the control group. However, magnesium supplementation did not have any significant effect on serum calcium (WMD, −0.09 mg/dL; 95% CI, −0.27 to 0.08; p = 0.294) level when compared with the control group. This meta-analysis demonstrated that magnesium supplementation significantly increased Serum magnesium levels which may have played an indirect role in improved clinical symptoms in patients with type 2 diabetes.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"11 1","pages":"133 - 145"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48310160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
This study was conducted to analyze the status of medical food selection process in hospitals within Busan and Gyeongnam area. The survey was distributed to 396 hospitals (general, tertiary and long-term care hospitals) and finally 68 surveys were used for analysis. The questionnaire consisted of 9 general items and 10 items related to enteral nutrition (EN). From the survey we found out that general hospitals and tertiary hospitals normally hire clinical dietitian, while long-term care hospitals hire dietitians with no further qualifications (χ2 = 27.918, p < 0.001). A significant relationship was found between hospital size and the priority for choosing medical foods for patients (χ2 = 11.852, p < 0.05). In general and tertiary hospitals, medical foods were provided exactly according to the doctor's prescription, whereas in long-term care hospitals, only half followed the doctor’s direction and half of them provided the products that has been conventionally used. There was also a significant relationship between hospital size and the method for determination of nutrition requirements (χ2 = 20.496, p < 0.001). Finally, the priority of considerations when developing a ‘medical food guidelines’ was shown in the following order; 1) the type of medical food that can be selected according to the disease state, 2) the nutrient content and comparison table for commercial products, and 3) how to manage complications that may occur when supplying medical food for patients. Developing an EN practice guideline for making a sensible selection of medical foods will provide a valuable information for better patient care.

Through a survey on dietary intake of children and adolescents with brain lesions, the present study aimed to analyze the current status of nutrient intake and examine the effect of high-protein nutrient drink on their nutritional and muscle statuses. The study participants were 90 juvenile participants aged 8–19 years, with brain lesions. The participants were provided with a protein nutrient drink for 12 weeks and a questionnaire survey on dietary intake was performed to analyze the level of nutrient intake before and after ingestion. The physical measurements were taken to determine the improvements in nutrient and muscle statuses. The results showed that, before the intake of protein nutrient drink as a supplement, the participants exhibited lower height, weight, and body mass index than those of the standard levels of healthy individuals, and the level of nutrient intake through diet was lower than those of the required and recommended levels of nutrient intake for Koreans. Conversely, after the intake of protein nutrient drink for 12 weeks, the level of nutrient intake and physical statuses such as weight showed significant improvements. In addition, the muscle status had undergone approximately 10% of change during the intervention with no significant difference. Thus, to ensure an adequate level of nutrient supply to children and adolescents with brain lesions, there is an urgent need to develop a guideline of nutrient intake. The findings in this study are expected to serve as the basic data for such guidelines.
