Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection and malnutrition negatively reinforce each other. Malnutrition leads to further immune deficiency and accelerates disease progression. The present overview aimed to investigate the current knowledge from review articles on the role of nutrition interventions as well as food and nutrition policies on HIV-related outcomes in adults to present future strategies for strengthening food and nutrition response to HIV. METHODS We searched PubMed/Medline, Scopus, Embase, ProQuest, and Ovid databases using the relevant keywords. The search was limited to studies published in English until April 2022. All types of reviews studies (systematic review, narrative review, and other types of review studies) which evaluated the impact of nutritional program/interventions on HIV progression were included. RESULTS Although nutrition programs in HIV care have resulted in improvements in nutritional symptoms and increase the quality life of HIV patients, these programs should evaluate the nutritional health of HIV-infected patients in a way that can be sustainable in the long term. In additions, demographic, clinical, and nutritional, social characteristics influence nutritional outcomes, which provide potential opportunities for future research. CONCLUSION Nutrition assessment, education and counseling, and food supplements where necessary should be an integral part of HIV treatment programs.

Abstract
Background Since the release of previous meta-analyses, some studies on the associations between fruit and vegetable intake with gastric cancer risk have been published. Therefore, we aimed to update the previous meta-analyses on these associations by including recently published studies as well as considering the main limitations of those meta-analyses. Methods A comprehensive search was conducted in online databases including PubMed, Scopus, ISI Web of Science, and Google Scholar to detect relevant prospective cohort studies published up to October 2021. Summary relative risks (RRs) were estimated using a random-effects model. Results Overall, 17 articles containing 18 prospective studies with a total sample size of 1,527,995 participants, aged between 18 and 90 years, were included in the current meta-analysis. During the follow-up periods ranging between 4.5 and 21 years, 8,477 cases of gastric cancer were diagnosed. A higher intake of total fruit [RR: 0.87, 95% confidence interval (CI): 0.80 to 0.94, I 2 = 0%] and total fruit and vegetable (RR: 0.75, 95% CI: 0.61 to 0.93, I 2 = 55.2%) were associated with a lower risk of gastric cancer. For total vegetable intake, a significant inverse association was found among the studies that controlled their analysis for energy intake. Based on the linear dose-response analysis, each 100 g/day increase in total fruit intake (Pooled RR: 0.95, 95% CI: 0.90 to 0.99, I 2 = 49%) and 200 g/day increase in total fruit and vegetable intake (RR: 0.94, 95% CI: 0.88 to 0.99, I 2 = 37.6%) were associated with a 5 and 6% lower risk of gastric cancer, respectively. Conclusion Fruit and vegetable consumption has a protective association with gastric cancer risk.

Effects of Probiotics Supplementation on CRP, IL-6, and Length of ICU Stay in Traumatic Brain Injuries and Multiple Trauma Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Evid Based Complement Alternat Med 2022; 2022:4674000.

Abstract
METHOD This meta-analysis aims to evaluate the effectiveness of probiotics in reducing inflammatory biomarkers and the length of intensive care unit (ICU) stays. PubMed-Medline, SCOPUS, Embase, and Google Scholar databases up to July 2021 were searched. The meta-analysis was carried out using random-effect analysis. To determine the sources of heterogeneity, subgroup analyses were performed. In case of the presence of publication bias, trim and fill analysis was carried out. The Cochrane Collaboration tool was used for checking the quality assessment. We hypothesized that probiotics would improve inflammatory markers (CRP and IL-6) and the length of ICU stay in traumatic brain injury and multiple trauma patients. RESULTS The present meta-analysis, which includes a total of seven studies, showed that there were no significant effects of probiotics supplementation on interleukin (IL)-6 (Hedges's g = -2.46 pg/ml; 95% CI: -12.16, 7.25; P=0.39), C-reactive protein (CRP) (Hedges's g = -1.10 mg/L; 95% CI: -2.27, 0.06; P=0.06), and the length of staying in ICU. The overall number of RCTs included in the analysis and the total sample size were insufficient to make firm conclusions. CONCLUSION As a result, more carefully designed RCTs are needed to investigate the effect of probiotics on inflammatory biomarkers and the length of ICU stay in traumatic brain injuries and multiple trauma patients in greater detail.

Abstract
Background: Traffic Light Labeling (TLL) system is a simple tool to communicate information regarding the nutrients content of food products and has been widely applied to promote public health. However, evidence on the effectiveness of the TLL system on consumers’ choices is conflicting. The present study aims to systematically summarize the effects of TLL on consumers’ point of purchase behaviors.
Methods: Five electronic databases, including PubMed/Medline, Scopus, Web of knowledge, the Cochrane library, and Science direct were searched from 2000/01/01 to 2021/11/01. Randomized-controlled trials, in English or Farsi languages, investigating the effects of TLL on choosing healthier foodstuffs or beverages were examined for eligibility and included in the review. Of 6408 potentially relevant publications (including 1255 duplicates), five clinical trials were finally included in the study.
Results: The duration of the interventions ranged from 4 to 12 weeks and all studies except one had high methodological quality. Out of 5, three clinical trials did not show positive effects of TLL on customers' choices to purchase healthier food products.
Conclusions: The present review showed that TLL without other public health-promoting interventions may have no substantial effects on consumer’s food choice.

Abstract
Background Inositol is a sugar‐alcohol and recognized as a key component of cell membrane phospholipids. It has crucial role in the cell signaling pathways and contribute to improving glycemic responses. Although some earlier studies have revealed the effect of inositol mediating glucose uptake by improving insulin sensitivity, the benefit of inositol supplementation in patients with overweight and obesity is not completely understood. This study aimed to assess the impact of inositol supplementation on body mass index (BMI) through a systematic review and meta‐analysis of controlled clinical trials. Methods A systematic search was performed to August 2021 in the following databases: PubMed‐Medline, Embase, Web of Science and Scopus. Fifteen controlled clinical trials investigating the effect of inositol on adult's BMI were finally included in the study. A random‐effects model was employed to estimate the effect size. Subgroup analysis was performed by dose, duration, age, type of inositol. Meta‐regression was used to investigate presence of any linear relationship. Begg's and Egger's tests were carried out to detect small study effect. Results The results of pooled analysis showed that inositol supplementation significantly decreased BMI scores (WMD = −0.41 kg/m2; 95% CI: −0.78, −0.04; p = 0.028). Subgroup analysis was performed to identify the source of heterogeneity among studies (I2 = 73.9%, p < 0.001), demonstrating supplementation duration, baseline BMI, mean age of participants, type of inositol and dosage were potential sources of heterogeneity. The effect of intervention was more clinically significant in participants with polycystic ovary syndrome (PCOS) and overweight/obesity. Inositol in the form of myo‐inositol (MI) had stronger effect on BMI reduction. Conclusion The meta‐analysis suggests that oral inositol supplementation has positive effect on BMI reduction. Inositol supplementation could be considered as an adjunct treatment to improve body mass index.

Abstract
BACKGROUND/OBJECTIVES Clinical efficacy of zinc (Zn) supplementation in the improvement of oxidative stress biomarkers has been investigated in some clinical trial studies. The purpose of the current dose-response meta-analysis is to systematically aggregate and evaluate all related studies to highlight the possible effect of Zn supplementation on oxidative stress. METHODS Systematic search was performed on Scopus, PubMed/Medline, Web of Science and Embase up to 31 December 2020. The random effect method was used to perform pooled analysis. Possible sources of heterogeneity were found using subgroup analysis and meta-regression. In the presence of publication bias, trim and fill analysis was performed to adjust the results. Non-linear relationship between effect size and variables was investigated by performing dose-response analysis. The quality of included studies was assessed using Cochrane Collaboration's tool. RESULTS Pooled-analysis of 18 studies showed that Zn supplementation improved MDA and Hcys levels (SMD = -1.53 μmol/L; 95% CI: -2.22, -0.85; P < .001 and SMD = -0.62 μmol/L; 95% CI: -1.08, -0.15; P < .001, respectively). There was no significant effect of Zn supplementation on TBARS (SMD = -0.59 μmol/l; 95% CI: -1.31, 0.13; P = .108). Zn had maximum reducing effect on MDA in <40 mg/day dosage. CONCLUSION Zn supplementation reduces MDA and Hcys levels, but not TBARS level. Supplementation with Zn <40 mg/day has an optimum effect on MDA level. Zn supplementation could be considered clinically as a beneficial approach in amending oxidative stress.
