Abstract
Background: The objective of this systematic review and meta-analysis was: (i) to examine the association between wine consumption and cardiovascular mortality, cardiovascular disease (CVD), and coronary heart disease (CHD) and (ii) to analyse whether this association could be influenced by personal and study factors, including the participants' mean age, the percentage of female subjects, follow-up time and percentage of current smokers. Methods: In order to conduct this systematic review and meta-analysis, we searched several databases for longitudinal studies from their inception to March 2023. This study was previously registered with PROSPERO (CRD42021293568). Results: This systematic review included 25 studies, of which the meta-analysis included 22 studies. The pooled RR for the association of wine consumption and the risk of CHD using the DerSimonian and Laird approach was 0.76 (95% CIs: 0.69, 0.84), for the risk of CVD was 0.83 (95% CIs: 0.70, 0.98), and for the risk of cardiovascular mortality was 0.73 (95% CIs: 0.59, 0.90). Conclusions: This research revealed that wine consumption has an inverse relationship to cardiovascular mortality, CVD, and CHD. Age, the proportion of women in the samples, and follow-up time did not influence this association. Interpreting these findings with prudence was necessary because increasing wine intake might be harmful to individuals who are vulnerable to alcohol because of age, medication, or their pathologies.

Ophthalmic epidemiology. 2023;(3):230-238
Abstract
PURPOSE Vascular endothelial growth factor (VEGF) has obvious clinical value in diabetes, but the conclusions on the diagnostic value of diabetic retinopathy (DR) are not consistent. This study aims to comprehensively evaluate the accuracy of circulating VEGF in the diagnosis of DR in the Asian population by a method of meta-analysis. METHODS PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), and China Wanfang Databases were searched for relevant studies on the diagnostic value of VEGF for DR in Asia up to November 2021. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and areas under the curve (AUC) were calculated by Stata 15.0 software. RESULTS After screening, eight eligible studies were enrolled, including 547 patients with DR. The results of the meta-analysis showed that the pooled DOR, sensitivity, specificity, PLR, and NLR were 31.67 (95%CI: 13.55 ~ 74.05), 0.86 (95%CI: 0.74 ~ 0.93), 0.84 (95%CI: 0.80 ~ 0.87), 5.33 (95%CI: 4.09 ~ 6.93), 0.17 (95%CI: 0.09 ~ 0.32), respectively. The AUC was 0.86 (95%CI: 0.82 ~ 0.89). CONCLUSION Circulating VEGF has a good diagnostic value in DR in the Asian population, with the potential to be an early diagnostic marker for DR.

Abstract
BACKGROUND Growing evidence suggests low and high maternal hemoglobin (Hb) concentrations may have adverse consequences for maternal and child health. There remain questions on specific Hb thresholds to define anemia and high Hb as well as how cutoffs may vary by anemia etiology and timing of assessment. METHODS We conducted an updated systematic review (using PubMed and Cochrane Review) on low (< 110 g/L) and high (≥ 130 g/L) maternal Hb concentrations and associations with a range of maternal and infant health outcomes. We examined associations by timing of Hb assessment (preconception; first, second, and third trimesters, as well as at any time point in pregnancy), varying cutoffs used for defining low and high hemoglobin concentrations and performed stratified analyses by iron-deficiency anemia. We conducted meta-analyses to obtain odds ratios (OR) and 95% confidence intervals. RESULTS The updated systematic review included 148 studies. Low maternal Hb at any time point in pregnancy was associated with: low birthweight, LBW (OR (95% CI) 1.28 (1.22-1.35)), very low birthweight, VLBW (2.15 (1.47-3.13)), preterm birth, PTB (1.35 (1.29-1.42)), small-for-gestational age, SGA (1.11 (1.02-1.19)), stillbirth 1.43 (1.24-1.65)), perinatal mortality (1.75 (1.28-2.39)), neonatal mortality (1.25 (1.16-1.34), postpartum hemorrhage (1.69 (1.45-1.97)), transfusion (3.68 (2.58-5.26)), pre-eclampsia (1.57 (1.23-2.01)), and prenatal depression (1.44 (1.24-1.68)). For maternal mortality, the OR was higher for Hb < 90 (4.83 (2.17-10.74)) than for Hb < 100 (2.87 (1.08-7.67)). High maternal Hb was associated with: VLBW (1.35 (1.16-1.57)), PTB (1.12 (1.00-1.25)), SGA (1.17 (1.09-1.25)), stillbirth (1.32 (1.09-1.60)), maternal mortality (2.01 (1.12-3.61)), gestational diabetes (1.71 (1.19-2.46)), and pre-eclampsia (1.34 (1.16-1.56)). Stronger associations were noted earlier in pregnancy for low Hb and adverse birth outcomes while the role of timing of high Hb was inconsistent. Lower Hb cutoffs were associated with greater odds of poor outcomes; for high Hb, data were too limited to identify patterns. Information on anemia etiology was limited; relationships did not vary by iron-deficiency anemia. CONCLUSION Both low and high maternal Hb concentrations during pregnancy are strong predictors of adverse maternal and infant health outcomes. Additional research is needed to establish healthy reference ranges and design effective interventions to optimize maternal Hb during pregnancy.

Abstract
BACKGROUND Insulin-like growth factor (IGF-1) is associated with breast cancer in menopausal women. Naturally occurring biomolecules found in common dietary protocols, such as flavonoids, play a key role in the inhibition and treatment of cancer. In-vitro/in-vivo studies showed that treatment involving flavonoids led to a reduced risk of breast cancer due to the decrease of IGF-1 level in addition to an increased insulin-like growth factor binding protein (IGFBP)-3. However, clinical studies did not show conclusive results in this regard because they are contradictory. OBJECTIVE The aim of the present study was to find the effect of flavonoids on IGF-1 and IGFBP-3 and the incidence of breast cancer. METHODS This systematic review was performed using PubMed, Scopus, ISI Web of Science, and EMBASE databases to collect results about the clinical use of flavonoids and their effects on breast cancer. After eliminating duplicate articles, the title and abstract of the remaining articles were examined in thematic communication, and related clinical articles were selected and studied based on inclusion criteria. The data were extracted from each article, and then statistical analysis was subsequently carried out by Comprehensive Meta-Analysis. RESULTS The results showed that the effect of flavonoids on changes in IGF1 and IGFBP-3 was not statistically significant. No significant heterogeneity was detected across the studies. Pooled effect size also indicated that the mean change was not statistically significant. No significant heterogeneity was detected across the studies. There was no evidence of publication bias for IGF1 and IGFBP-3. CONCLUSION This meta-analysis study suggests that flavonoid supplementations have no significant effect on IGF-1 and IGFBP-3, and a high soy diet has beneficial effects on IGF system components, which might be useful in breast cancer.

Abstract
BACKGROUND & AIMS The evolving epidemiologic patterns of inflammatory bowel disease (IBD) throughout the world, in conjunction with advances in therapeutic treatments, may influence hospitalization rates of IBD. We performed a systematic review with temporal analysis of hospitalization rates for IBD across the world in the 21st century. METHODS We systematically reviewed Medline and Embase for population-based studies reporting hospitalization rates for IBD, Crohn's disease (CD), or ulcerative colitis (UC) in the 21st century. Log-linear models were used to calculate the average annual percentage change (AAPC) with associated 95% confidence intervals (95% CIs). Random-effects meta-analysis pooled country-level AAPCs. Data were stratified by the epidemiologic stage of a region: compounding prevalence (stage 3) in North America, Western Europe, and Oceania vs acceleration of incidence (stage 2) in Asia, Eastern Europe, and Latin America vs emergence (stage 1) in developing countries. RESULTS Hospitalization rates for a primary diagnosis of IBD were stable in countries in stage 3 (AAPC, -0.13%; 95% CI, -0.72 to 0.97), CD (AAPC, 0.20%; 95% CI, -1.78 to 2.17), and UC (AAPC, 0.02%; 95% CI, -0.91 to 0.94). In contrast, hospitalization rates for a primary diagnosis were increasing in countries in stage 2 for IBD (AAPC, 4.44%; 95% CI, 2.75 to 6.14), CD (AAPC, 8.34%; 95% CI, 4.38 to 12.29), and UC (AAPC, 3.90; 95% CI, 1.29 to 6.52). No population-based studies were available for developing regions in stage 1 (emergence). CONCLUSIONS Hospitalization rates for IBD are stabilizing in countries in stage 3, whereas newly industrialized countries in stage 2 have rapidly increasing hospitalization rates, contributing to an increasing burden on global health care systems.

Screening for Lipid Disorders in Children and Adolescents: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force.
Guirguis-Blake, JM, Evans, CV, Coppola, EL, Redmond, N, Perdue, LA
JAMA. 2023;(3):261-274
Abstract
IMPORTANCE Lipid screening in childhood and adolescence can lead to early dyslipidemia diagnosis. The long-term benefits of lipid screening and subsequent treatment in this population are uncertain. OBJECTIVE To review benefits and harms of screening and treatment of pediatric dyslipidemia due to familial hypercholesterolemia (FH) and multifactorial dyslipidemia. DATA SOURCES MEDLINE and the Cochrane Central Register of Controlled Trials through May 16, 2022; literature surveillance through March 24, 2023. STUDY SELECTION English-language randomized clinical trials (RCTs) of lipid screening; recent, large US cohort studies reporting diagnostic yield or screen positivity; and RCTs of lipid-lowering interventions. DATA EXTRACTION AND SYNTHESIS Single extraction, verified by a second reviewer. Quantitative synthesis using random-effects meta-analysis. MAIN OUTCOMES AND MEASURES Health outcomes, diagnostic yield, intermediate outcomes, behavioral outcomes, and harms. RESULTS Forty-three studies were included (n = 491 516). No RCTs directly addressed screening effectiveness and harms. Three US studies (n = 395 465) reported prevalence of phenotypically defined FH of 0.2% to 0.4% (1:250 to 1:500). Five studies (n = 142 257) reported multifactorial dyslipidemia prevalence; the prevalence of elevated total cholesterol level (≥200 mg/dL) was 7.1% to 9.4% and of any lipid abnormality was 19.2%. Ten RCTs in children and adolescents with FH (n = 1230) demonstrated that statins were associated with an 81- to 82-mg/dL greater mean reduction in levels of total cholesterol and LDL-C compared with placebo at up to 2 years. Nonstatin-drug trials showed statistically significant lowering of lipid levels in FH populations, but few studies were available for any single drug. Observational studies suggest that statin treatment for FH starting in childhood or adolescence reduces long-term cardiovascular disease risk. Two multifactorial dyslipidemia behavioral counseling trials (n = 934) demonstrated 3- to 6-mg/dL greater reductions in total cholesterol levels compared with the control group, but findings did not persist at longest follow-up. Harms reported in the short-term drug trials were similar in the intervention and control groups. CONCLUSIONS AND RELEVANCE No direct evidence on the benefits or harms of pediatric lipid screening was identified. While multifactorial dyslipidemia is common, no evidence was found that treatment is effective for this condition. In contrast, FH is relatively rare; evidence shows that statins reduce lipid levels in children with FH, and observational studies suggest that such treatment has long-term benefit for this condition.

Abstract
BACKGROUND Correction of calcium, phosphorus, and parathyroid hormone disorders is the standard of treatment in nondialysis patients with chronic kidney disease-mineral and bone disorder (CKD-MBD). However, the side effects and adverse reactions are still the main problems. Moreover, the lack of protection of kidney function in the treatment dramatically affects patients' health. Although Traditional Chinese Medicine, specifically tonifying kidney and strengthen bone (TKSB) therapy, is wildly applied to patients with CKD-MBD in China, the evidence of TKSB therapy in the treatment of CKD-MBD is limited. Thus, we conducted this meta-analysis to evaluate the efficacy and safety of TKSB therapy combined with Western medicine (WM) for nondialysis patients with CKD-MBD. METHODS Two investigators conducted systematic research of randomized controlled trials of TKSB therapy for CKD-MBD from 7 electronic databases. Methodological quality evaluations were performed using the Cochrane collaboration tool, and data analysis was conducted by RevMan v5.3 software and STATA v15.0. RESULTS In total, 8 randomized controlled trials involving 310 patients met the criteria of meta-analysis. The complete results showed that compared with WM alone, TKSB treatment could improve the clinical efficacy rate (risk ratio = 4.49, 95% confidence interval [CI]: [2.64, 7.61], P .00001), calcium (weighted mean difference [WMD] = 0.11, 95% CI: [0.08, 0.14], P < .00001), serum creatinine (WMD = 45.58, 95% CI: [32.35, 58.8], P < .00001) phosphorus (WMD = 0.11, 95% CI: [0.08, 0.13], P < .00001), parathyroid hormone (WMD = 16.72, 95% CI: [12.89, 20.55], P < .00001), blood urea nitrogen levels (WMD = 0.95, 95% CI: [0.26, 1.64], P = .007) on nondialysis patients with CKD-MBD, which was beneficial to improve the patients' bone metabolic state and renal function. In addition, evidence shows that, compared with WM alone, TKSB treatment is safe and does not increase side effects. CONCLUSION The systematic review found that TKSB therapy combined with WM has a positive effect on improving renal function and correcting bone metabolism disorder in nondialysis patients with CKD-MBD, which shows that Traditional Chinese Medicine is effective and safe in treating CKD-MBD. However, more high-quality, large-sample, multicenter clinical trials should be conducted to assess the safety and efficacy of TKSB therapy in treating nondialysis patients with CKD-MBD.Systematic review registration: INPLASY2020120086.

Predictive Value of Geriatric Nutritional Risk Index in Patients with Colorectal Cancer: A Meta-Analysis.
Xu, J, Sun, Y, Gong, D, Fan, Y
Nutrition and cancer. 2023;(1):24-32
Abstract
Geriatric Nutritional Risk Index (GNRI) has been used as a predictor of adverse prognosis in patients with colorectal cancer (CRC). This meta-analysis sought to evaluate the prognostic role of GNRI in CRC patients. Two authors comprehensively searched the studies indexed in PubMed and Embase databases until March 15, 2022. Only observational studies evaluating the association between GNRI and adverse outcomes in patients with CRC were eligible. The prognostic value of GNRI was expressed by pooling the adjusted hazard ratio (HR) with 95% confidence intervals (CI) for the low vs. high GNRI group. Eight retrospective studies enrolling 3239 CRC patients were included. When comparing the low with the high GNRI group, the pooled HR was 2.40 (95% CI 1.71-3.39) for overall survival, 1.63 (95% CI 1.35-1.96) for disease-free survival, and 1.85 (95% CI 1.21-1.83) for ≥ 2 Clavien-Dindo Grade postoperative complications, respectively. Moreover, malnutrition defined by the cutoff GNRI at 98 was associated with a reduced overall survival (HR 1.66; 95% CI 1.37-2.02). Low GNRI score may be a promising predictor of postoperative complications and long-term poor survival in Asian patients with CRC. Malnutrition defined by the GNRI can be applied to improve risk stratification of CRC.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a common comorbidity of type 2 diabetes mellitus (T2DM). Our aim is to investigate the effects of liraglutide on T2DM with NAFLD. METHODS Relevant articles published from the earliest publication to March 2022 were selected from several databases. The Cochrane Collaboration's RevMan software was used for the analysis. RESULTS Sixteen studies are selected for this meta-analysis, which includes totally 634 patients in the treatment group and 630 patients in the control group. As a result, 14 studies show that fasting plasma glucose levels of the experimental group are lower than that of the control group; 15 studies show that glycosylated hemoglobin A1c levels of the experimental group are lower than that of the control group; 13 studies show that triglyceride levels of the experimental group are lower than that of the control group; twelve studies show that total cholesterol levels of the experimental group are lower than that of the control group; 10 studies show that alanine aminotransferase levels of the experimental group is lower than that of the control group; 10 studies show that no significant difference in changes in aspartate transaminase between 2 groups; 13 studies show that low density lipoprotein cholesterol levels of the experimental group is lower than that of the control group; 9 studies show that no significant difference in changes in high density lipoprotein cholesterol between 2 groups; 7 studies mentioned adverse effects and the difference is significant. CONCLUSION Liraglutide is potentially curative for T2DM with NAFLD.

Nutrients. 2023;(9)
Abstract
Female breast cancer is the most frequently diagnosed cancer. The long-term survival rates for this disease have increased; however, the unique demand for high-quality healthcare to improve breast-cancer survivorship are commonly unmet. The Mediterranean diet (MD) is associated with reduced breast-cancer risk and various health-related benefits in the general population, but its effect on breast-cancer survivors remains uncertain. The objective of this systematic review and meta-analysis was to assess current evidence from randomised controlled trials (RCTs) and observational studies (cohort, cross-sectional and case-control) regarding the effect of the MD on survival, quality of life (QoL) and health-related outcomes in female breast-cancer survivors. MEDLINE, EMBASE, Web of Science and the Cochrane library were searched for studies published before and including April 2022. Two reviewers independently screened the literature and completed the data extraction and risk-of-bias assessment. Eleven studies (fifteen reports) were included, including two RCTs, four cohort and five cross-sectional studies. The meta-analysis of the cohort studies showed strong evidence of an inverse association between high adherence to the MD and all-cause mortality (hazard ratio (HR) 0.78, 95% confidence interval (CI) 0.66-0.93, I2: 0%, Grading of Recommendations Assessment, Development and Evaluation (GRADE) = low certainty of evidence) and non-breast-cancer mortality (HR 0.67, 95% CI 0.50-0.90, I2: 0%, GRADE = very low certainty of evidence). The associations between high adherence to the MD and QoL and health-related parameters were not consistent. These findings highlight the potential of adherence to the MD to reduce the risk of mortality. Future research with better study designs, as well as more consistent measurements of QoL and MD adherence, taking into account changes in MD adherence over time and population subgroups, is needed to provide more robust evidence on the survival, QoL and health-related outcomes in BC survivors.
