The Relationship

Elevated levels of proinflammatory markers are evident in patients with diabetic retinopathy (DR) and are associated with disease progression and prognosis. Intercellular adhesion molecule-1 (ICAM-1) is involved in inflammation and acts as a local intensifying signal in the pathological processes associated with chronic eye inflammation. The aim of this systematic review and meta-analysis was to investigate the relationship between ICAM-1 level and DR. Online electronic databases were searched to retrieve all relevant articles published before December 2017. The standard mean difference (SMD) and their 95% CI were included and then pooled with a random effects model. Subgroup analysis and metaregression analysis were applied to explore the sources of heterogeneity, and publication bias was calculated to assess the quality of pooled studies. A total of 11 articles, containing 428 patients with DR and 789 healthy controls, were included in this meta-analysis. The results indicated a significant increase in ICAM-1 level in the DR group compared with the control group (SMD: 1.20, 95%CI 0.83 to 1.57, p<0.001). Subgroup analyses and metaregression analysis indicated that publication year, region, study method, diabetes mellitus type, Newcastle-Ottawa Scale and sample size were not the potential sources of heterogeneity. The results of this current meta-analysis indicated that the increased level of ICAM-1 generally exists in the patients with DR and it may associated with the severity of DR. However, large-scale and high-quality studies are required to confirm this finding in the future.

The Relationship

Objective. At present, the relationship between autophagosomes and the prognosis of various cancers has become a subject of active investigation. A series of studies have demonstrated the correlation between autophagy microtubule-associated protein light chain 3 (LC-3), Beclin-1, and colorectal cancer (CRC). Since autophagy has dual regulatory roles in tumors, the results of this correlation are also uncertain. Hence, we summarized the relationship between Beclin-1, LC-3, and CRC using systematic reviews and meta-analysis to clarify their prognostic significance in it. Methods. PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched online up to April 1, 2019. The quality of the involving studies was assessed against the Newcastle-Ottawa Scale (NOS). Pooled hazard ratio (HR) and 95% confidence interval (CI) in a fixed or random effects model were used to assess the strength of correlation between Beclin-1, LC-3, and CRC. Results. A total of 9 articles were collected, involving 2,297 patients. Most literatures scored more than 6 points, suggesting that the quality of our including research was acceptable. Our finding suggested that the expression of Beclin-1 was not associated with overall survival (HR = 0.68, 95% CI (0.31–1.52), P=0.351). Nonetheless, LC-3 expression exerted significant impact on OS (HR = 0.51, 95% CI (0.35–0.74), P<0.05). Subgroup analysis exhibited that Beclin-1 expression was associated with OS at TNM stage III (HR = 0.04, 95% CI = 0.02–0.08, P<0.05), surgical treatment (HR = 1.53, 95% CI (1.15–2.02), P=0.003), and comprehensive treatment (HR = 0.27 95% CI (0.08–0.92), P=0.036), respectively. Similarly, the results showed the increased LC-3 expression in CRC was related to OS in multivariate analyses (HR = 0.44, 95% CI (0.34–0.57), P<0.05), stages (HR = 0.51, 95% CI (0.35–0.74), P<0.05), and comprehensive treatment (HR = 0.44, 95% CI (0.34–0.57), P<0.05). Conclusions. Autophagy-related proteins of LC-3 might be an important marker of CRC progression. However, since the number of the original studies was limited, more well-designed, large-scale, high-quality studies are warranted to provide more convincing and reliable information.

Purpose: To investigate the expression of various angiogenesis and inflammation mediators in the vitreous fluid of eyes with proliferative diabetic retinopathy (PDR).Methods: A total of 38 eyes with PDR and 37 control eyes were included. Vitreous fluid was collected during vitrectomy. Vitreous levels of colony stimulating factor-1 receptor (CSF-1R), syndecan-1, placental growth factor (PIGF), and angiopoietin-like protein 4 (ANGPTL-4) were measured by multiplex immunoassay. Vitreous levels of vascular endothelial growth factor (VEGF), interleukin-6 (IL-6), interleukin-8 (IL-8), monocyte chemotactic protein-1 (MCP-1), tumor necrosis factor-α (TNF-α), and intercellular adhesion molecule-1 (ICAM-1) were measured by cytometric beads array. Levels of these mediators were compared between the PDR and control eyes. Correlations between levels of different mediators and between these mediators and kidney function metrics in the PDR group were also analyzed.Results: Vitreous levels of syndecan-1, PIGF, ANGPTL-4, VEGF, and IL-8 were significantly higher in the PDR group compared to the control group (all p &lt; 0.05). Levels of VEGF were significantly correlated with levels of syndecan-1, PIGF, and ANGPTL-4 (r = 0.370 to 0.497, all p &lt; 0.05). Significant positive correlations were detected between levels of any two of the following mediators including syndecan-1, PIGF, ANGPTL-4, and IL-8 (r = 0.370 to 0.906, all p &lt; 0.05). Apart from VEGF, levels of these mediators were positively correlated with serum creatinine and blood urea nitrogen (r = 0.328 to 0.638, all p &lt; 0.05), and negatively correlated with fasting blood glucose and estimated glomerular filtration rate (r = −0.325 to −0.603, all p &lt; 0.05).Conclusions: Correlations between different angiogenesis and inflammation mediators were observed in eyes with PDR, suggesting cross-talks of different angiogenesis and inflammation pathways in the pathogenesis of PDR. The levels of angiogenesis and inflammation in PDR are correlated with kidney damage, indicating possible common pathways in diabetic retinopathy and nephropathy.

Abstract Background: To assess the relationship between delivery mode and postpartum depression and to examine whether cesarean section (CS) has a higher risk of postpartum depression than vaginal delivery (VD). Methods: We searched the Cochrane Library, PubMed, and EMBASE from inception to 30 April 2019 without language limitations. Two authors independently selected studies, assessed the quality of included studies, and extracted data. Any disagreements were resolved by discussion with a third author. We used the Newcastle-Ottawa Scale and GRADE methods to assess the quality of the included studies and evidences. This study had four included cohort studies data and carried out fixed-effect model meta-analysis. Results: The findings demonstrated a significant difference in the risk of postpartum depression between CS and VD. Compared with the control group, the CS group was associated with a higher prevalence of postpartum depression symptoms (Risk Ratio =1.29; 95% CI: 1.11-1.51). Conclusions: The findings supported a relationship between delivery mode and postpartum depression. Particularly, we found that CS is associated with a higher risk of postpartum depression. Therefore, we ought to encourage pregnant women who are without medical indication of CS to select VD.r Trial registration: The protocol of this systematic review was registered in the PROSPERO under the number CRD42019148154.

Purpose: to assess the levels of Hypoxia-inducible factor-1α (HIF-1α) and intercellular adhesion molecule-1 (ICAM-1) in vitreous of proliferative diabetic retinopathy patients which were given intravitreal bevacizumab (IVB), as well as its relation to the central macular thickness (CMT) measured prior to vitrectomy. Methods: thirty-two eyes were randomized into two groups, one that received an IVB injection at 1-2 weeks previtrectomy and the control group which did not receive any injection. Measurement of HIF-1α and ICAM-1 was conducted using enzyme-linked immunosorbent assay (ELISA). The CMT were measured at the initial visit, prior to vitrectomy, and at follow up time (2, 4, and 12 weeks postoperatively) using Stratus OCT. Results: The mean levels of HIF-1α vitreous (ng/mg protein) in the control group and IVB respectively 0.020 (0.006; 0.077) and 0.029 (0.016; 0.21). Vitreous levels of ICAM-1 (ng /mL) in control group and IVB group were 20.10 (3.41; 40.16) and 23.33 (0.63; 68.5). The mean levels of HIF-1α and ICAM-1 vitreous obtained did not differ significantly between the two groups. Conclusion: The levels of HIF-1α and ICAM-1 in PDR patients do not decrease after one injection of intravitreal Bevacizumab 1-2 weeks prior to vitrectomy. The concentration of vitreous HIF-1α and ICAM-1 are not directly related to the CMT.

e15099 Background: Thorax radiotherapy (TRT) combined with immunotherapy has shown promising results. However, it remains unclear whether TRT would increases the risk of immunotherapy related pneumonitis (IRP). Here, we performed a meta-analysis to compare the rates of IRP in patients treated with TRT to patients treated without TRT. Methods: A meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Two individual researchers conducted the platform searches on the PubMed upto Nov. 4th, 2019. Quality of studies was assessed independently by two researchers using the Cochrane Collaboration's tool for randomized clinical trials, and the Newcastle-Ottawa Scale for cohort studies. Any disagreements encountered were settled through senior authors. The single rate of pneumonitis along with the corresponding 95% confidence interval (CI) was estimated. The odds ratio (OR) and its 95% CI were computed using random-effects model after checking the heterogeneity across studies using the Cochran Q chi-square test and the I2 statistic. Data analyses were performed using R version 3.6.2, meta and metafor packages. Results: A total of 62 studies including 14648 patients on IRP were first selected. Thirteen studies had two arms data, 501 patients were in TRT arm, 1185 patients were in non-TRT arm. Two studies including 557 patients were treated with immunotherapy and concurrent/sequential TRT. The remaining 47 studies had no TRT patients or TRT data were unavailable. The pooled rate of any grade IRP of all 62 studies (14648 patients) was 6% (95% CI: 5%-8%). All grades IRP was significantly higher among patients treated with immunotherapy and TRT arm when compared to the non-TRT arm (OR = 1.44, 95% CI: 1.04-2.00, P = 0.030). In the subgroup analysis, no significance difference in IRP rate was found between patients with various cancer types or various types of immune checkpoint inhibitors (p = 0.7033, p = 0.7522, respectively). The rate of IRP in all TRT patients was 18% (95% CI: 13%-24%), comparing to 5% (95% CI: 4%-6%) in control group. Conclusions: This meta-analysis demonstrates that TRT combined immunotherapy had an elevated incidence of IRP compared to non-TRT (OR = 1.44, 95% CI: 1.04-2.00, P = 0.030). There remains a lack of data on risk factors of IRP in TRT patients, and future large-scale studies are warranted. To our knowledge, this is the first comprehensive meta-analysis of IRP for TRT patients.

Abstract Background Mind-body approaches, particularly yoga, are used by cancer survivors to cope with treatment-related symptoms. Consistency of yoga-related effects on treatment-related symptoms are not known. This meta-analysis was designed to examine effects of yoga on pre- to postintervention improvements in fatigue among cancer patients. Methods PubMed and PsycINFO were searched for peer-reviewed articles of yoga randomized controlled trials including cancer survivors and reporting at least one fatigue measure. Twenty-nine studies met inclusion criteria (n = 1828 patients). Effect sizes (Hedge’s g) were calculated for fatigue, depression, and quality of life. Patient-related and intervention-related characteristics were tested as moderators of outcomes. All statistical tests were two-sided. Results Yoga practice was associated with a small, statistically significant decrease in fatigue (g = 0.45, P = .013). Yoga type was a statistically significant moderator of this relationship (P = .02). Yoga was associated with a moderate decrease in depression (g = 0.72, P = .007) but was not associated with statistically significant changes in quality of life (P = .48). Session length was a statistically significant moderator of the relationship between yoga and depression (P = .004). Neither timing of treatment (during treatment vs posttreatment) nor clinical characteristics were statistically significant moderators of the effects of yoga on outcomes. The effect of yoga on fatigue and depression was larger when the comparator was a “waitlist” or “usual care” than when the control group was another active treatment (P = .036). Conclusions Results suggest yoga may be beneficial as a component of treatment for both fatigue and depression in cancer survivors.

AbstractObjectiveTo assess the relationship between opioid therapy for chronic noncancer pain and fracture risk by a meta-analysis of cohort studies and case-control studies.MethodsThe included cohort studies and case-control studies were identified by searching the PubMed and EMBASE databases from their inception until May 24, 2019. The outcome of interest was a fracture. This information was independently screened by two authors. When the heterogeneity among studies was significant, a random effects model was used to determine the overall combined risk estimate.ResultsIn total, 12 cohort studies and 6 case-control studies were included. We used the Newcastle-Ottawa Scale (NOS) to evaluate the quality of the included literature, and 14 of the studies were considered high-quality studies. The overall relative risk of opioid therapy and fractures was 1.78 (95% confidence interval (CI) 1.53 - 2.07). Subgroup analyses revealed sources of heterogeneity, sensitivity analysis was stable, and no publication bias was observed.ConclusionsThe meta-analysis showed that the use of opioids significantly increased the risk of fracture.

Background. Hypertension is a primary risk factor for cardiovascular disease (CVD). Tianma Gouteng decoction (TGD), originating from Zabingzhengzhixinyi, has been used for thousands of years in China to treat hypertension, giddiness, and migraine. This updated meta-analysis aimed at assessing the efficacy and safety of TGD combined with nifedipine in the treatment of primary hypertension. Methods. Related research published prior to September 1, 2019, was found in electronic databases without language limitations. Fourteen studies were selected and analyzed for specified criteria, including the quality of the studies. All outcomes were recorded exhaustive. Data management and analysis were performed using RevMan 5.3 software. Results. A total of 1,537 (769 cases in the experimental group and 768 cases in the control group) patients were enrolled. The total efficacy rate was improved significantly for the combination of nifedipine with TGD compared to nifedipine treatment alone (I2 = 22%, RR = 1.17, and 95% CI: 1.12 to 1.22). Traditional Chinese medicine (TCM) symptoms of patients were obviously improved in the experimental group than in the control group (I2 = 44%, RR = 1.26, and 95% CI: 1.17 to 1.36). TGD combined with nifedipine shows a better effect than nifedipine in decreasing diastolic blood pressure (I2 = 95%, MD = −5.32, and 95% CI: −8.19 to −2.45) and systolic blood pressure (I2 = 98%, MD = −9.35, and 95% CI: −15.03 to −3.67) of patients. A sensitivity analysis was conducted for SBP and DBP by removing 2 studies and recalculated the combined estimate on remaining studies. The results of SBP showed a small heterogeneity (I2 = 17%, MD = −13.95, 95% CI: −14.86 to −13.05, and P<0.00001) when two studies (shicaihong 2017 and xiaoyugao 2017) were removed. And the results of DBP showed no heterogeneity (I2 = 0, MD = −8.36, 95% CI: −8.91 to −7.81, and P<0.00001) when two studies (panzhixiong 2019 and shicaihong 2017) were removed. Conclusion. The combination of TGD and nifedipine has a better effect in the treatment of hypertension, including blood pressure lowering and patients’ TCMs improving. However, our findings must be handled with care because of the small sample size and low quality of clinic trials cited. Other rigorous and large-scale RCTs are in need to confirm these results.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.
