Association of oxidative balance score with helicobacter pylori infection and mortality in the US population.

Background: Limited research has examined the association between Oxidative Balance Score (OBS) and mortality, particularly in individuals with Helicobacter pylori (H. pylori) infection. This study investigates the correlation between OBS and H. pylori infection and their impacts on all-cause mortality within a cohort of individuals, considering both infected and uninfected individuals. Methods: Data from the National Health and Nutrition Examination Survey (NHANES) 1999-2018, comprising 4,532 participants, were analyzed. Logistic regression analyses assessed the relationship between H. pylori infection and relevant covariates. Cox regression and restricted cubic spline analysis evaluated the association between total OBS, lifestyle OBS, dietary OBS, and all-cause mortality in H. pylori-positive and -negative individuals. Results: Restricted cubic spline modeling revealed a linear relationship between total OBS and all-cause mortality, particularly in H. pylori-negative patients. Total OBS, dietary OBS, and lifestyle OBS inversely correlated with H. pylori infection, even after adjusting for confounders. Higher dietary OBS was associated with decreased mortality risk exclusively in H. pylori-positive individuals, while lifestyle OBS was associated with mortality only in H. pylori-negative individuals. These findings underscore the complex relationships between OBS, H. pylori infection, and mortality, stressing the importance of infection status in assessing oxidative balance's impact on health. Conclusion: In this sample, higher OBS was associated with lower H. pylori infection risks. Dietary OBS correlated significantly with all-cause mortality in H. pylori-positive individuals, while lifestyle OBS was notably associated with mortality in H. pylori-negative participants. Further research is necessary to elucidate the underlying mechanisms and clinical implications of these findings.

Association of dietary inflammatory index with helicobacter pylori infection and mortality among US population.

BACKGROUND: Limited research has been conducted on the potential relationship between the dietary inflammation index (DII) and mortality, particularly in individuals with Helicobacter pylori (H. pylori) infection. This study aimed to investigate the association between the DII and H. pylori infection, as well as their respective impacts on all-cause mortality in a cohort of individuals with or without H. pylori infection. METHODS: Data from the 1999-2018 National Health and Nutrition Examination Survey (NHANES) were utilized for this study, with a final of 4370 participants included. Both univariable and multivariable-adjusted logistic regression analyses were employed to explore the relationship between H. pylori infection and pertinent covariates. Cox regression analysis, as well as restricted regression cubic spline analysis, were utilized to assess the association between DII and all-cause mortality among individuals with or without H. pylori infection. RESULTS: The findings demonstrated a positive correlation between DII scores and H. pylori infection, even after adjusting for potential confounding factors. Moreover, higher DII scores were significantly associated with an elevated risk of mortality exclusively in individuals with H. pylori infection, while no such association was observed in the uninfected population. Additional analysis using restricted cubic spline modeling revealed a positive linear relationship between DII scores as a continuous variable and the adjusted risk of all-cause mortality specifically in H. pylori-infected patients. CONCLUSION: The results of this study indicated that DII was positively correlated with an increased risk of H. pylori infection and was associated with a heightened risk of all-cause mortality solely in individuals with H. pylori infection. Consequently, DII might serve as a useful tool for risk stratification in the H. pylori-infected population among U.S. adults. Further research is warranted to elucidate the underlying mechanisms and potential clinical implications of these findings.

Population attributable fractions of modifiable risk factors for microvascular complications of type 2 diabetes in China: An analysis using national cross-sectional data.

AIM: To assess the population attributable fractions (PAFs) for modifiable risk factors for microvascular complications of type 2 diabetes (T2D) in China. MATERIALS AND METHODS: Data collected from the China National HbA1c Surveillance System from 2009 to 2013 were used. The PAFs of four predefined risk factors, including an HbA1c of 7% or higher, blood pressure (BP) of 130/80 mmHg or higher, low-density lipoprotein-cholesterol (LDL-C) of 1.8 mmol/L or higher and body mass index (BMI) of 24 kg/m2 or higher, were calculated for diabetic microvascular complications, including diabetic retinopathy (DR), diabetic kidney disease (DKD) and distal symmetric polyneuropathy (DSPN). PAFs were further adjusted for age, sex and duration of diabetes. RESULTS: In total, there were 998 379 participants with T2D from nationwide mainland China included in this analysis. As for DR, an HbA1c of 7% or higher, BP of 130/80 mmHg or higher, LDL-C of 1.8 mmol/L or higher and BMI of 24 kg/m2 or higher conferred PAFs of 16.2%, 15.2%, 5.8% and 2.8%, respectively. In the case of DKD, BP of 130/80 mmHg or higher provided a PAF of 25.2%, followed by an HbA1c of 7% or higher (13.9%), BMI of 24 kg/m2 or higher (8.0%) and LDL-C of 1.8 mmol/L or higher (5.6%). As for DSPN, an HbA1c of 7% or higher, BP of 130/80 mmHg or higher, LDL-C of 1.8 mmol/L or higher and BMI of 24 kg/m2 or higher contributed to PAFs of 14.2%, 11.7%, 5.9% and 5.8%, respectively. PAFs for diabetic microvascular complications were mildly to moderately reduced after adjusting for participants' age, sex and duration of diabetes. CONCLUSIONS: Suboptimal glycaemic and BP control were the main contributors to diabetic microvascular complications, while the PAFs of unmet LDL-C and BMI control targets were quite limited for diabetic microvascular complications. In addition to glycaemic control, BP control should be especially prioritized in the management of diabetic microvascular complications to further reduce the disease burden.

Association between biologic therapy and fracture incidence in patients with selected rheumatic and autoimmune diseases: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To investigate the effect of biologic therapy on risk of fracture in selected rheumatic and autoimmune diseases. METHODS: The PubMed, Cochrane library, and EMBASE databases were systematically searched from the inception dates to June 4, 2021. Randomized clinical trials (RCTs) comparing biological disease-modifying antirheumatic drugs (bDMARDs) with non-bDMARDs or placebo in patients with five selected rheumatic and autoimmune diseases were included. Meta-analyses were conducted to calculate the odds ratio (OR) with 95 % confidence intervals (CIs) for major osteoporotic fracture, hip fracture, osteoporotic non-vertebral fracture, and total fracture. RESULTS: A total of 100 RCTs involving 51,413 participants fulfilled the inclusion criteria. In patients with psoriasis (Ps), and psoriatic arthritis (PsA), compared with placebo or non-bDMARDs therapy, the risk of major osteoporotic fracture (OR, 0.34 [95 %Cl, 0.15-0.76], p = 0.009), hip fracture (OR, 0.22 [95 %Cl, 0.05-0.89], p = 0.03), and osteoporotic non-vertebral fracture (OR, 0.26 [95 %Cl, 0.10-0.62], p = 0.003) were significantly decreased with the use of bDMARDs. In patients with rheumatoid arthritis (RA), axial spondyloarthritis (axSpA), systemic lupus erythematosus (SLE), and inflammatory bowel diseases (IBD), the risk of fracture were not changed with biologic treatment. CONCLUSIONS: The existing evidence from RCTs indicated the use of bDMARDs was associated with a low risk of major osteoporotic fracture, hip fracture, and osteoporotic non-vertebral fracture in patients with Ps and PsA. There are still urgent needs for studies regarding the actions of biologic therapies on the risk of bone fractures in systemic inflammatory diseases.

The Effects of Supervised Exercise Training on Weight Control and Other Metabolic Outcomes in Patients With Type 2 Diabetes: A Meta-Analysis.

Few studies have investigated the dose-response relationship between exercise and weight control. This study aimed to assess the effects of different types of supervised exercise training on weight control and other metabolic outcomes in patients with type 2 diabetes mellitus and explore the dose-response relationship between exercise volume/duration and these outcomes. PubMed/MEDLINE, Embase, and Cochrane databases were searched for studies between January 1980 and June 2019. Randomized control trials in type 2 diabetes mellitus patients with supervised exercise training versus control treatment were included. The primary outcome was changes in body weight (kg). The secondary outcomes included changes in waist circumference (cm) and total body fat percentage (%). Forty-two randomized control trials, including 3,625 patients with type 2 diabetes mellitus were included. Overall, exercise treatment was associated with significant reduction in body weight (weighted mean differences, -1.10 kg; 95% CI [-1.58, -0.62], p < .01), waist circumference (weighted mean differences, -2.51 cm; 95% CI [-3.25, -1.77], p < .01), and total body fat (weighted mean differences, -1.16%; 95% CI [-1.58%, -0.75%], p < .01). The percentage of total body fat was reduced by all types of exercise, with a significant difference between aerobic exercise and resistance exercise (p = .02) and a significant difference between combined exercise and resistance exercise (p < .01). A higher volume of aerobic exercise and a higher volume of resistance exercise were superior in reducing body weight. In conclusion, supervised exercise training improved metabolic outcomes in general, while different types and volume of exercises have their own merits.

SGLT2 inhibitors and lower limb complications: an updated meta-analysis.

BACKGROUND: To exam the associations between the use of sodium glucose co-transporter 2 inhibitor (SGLT2i) and the risk of lower limb complications, and to analyze the associated factors. METHODS: Pubmed, Medline, Embase, the Cochrane Center Register of Controlled Trials for Studies and Clinicaltrial.gov were searched from the inception to November 2020. Randomized controlled trials of SGLT2i conducted in population containing diabetic patients with reports of amputation, peripheral arterial disease (PAD) and diabetic foot (DF) events were included. Random-effect model, fixed-effect model and meta-regression analysis were accordingly used. RESULT: The numbers of SGLT2i users versus non-SGLT2i users in the analyses of amputation, PAD and DF were 40,925/33,414, 36,446/28,685 and 31,907/25,570 respectively. Compared with non-SGLT2i users, the risks of amputation and PAD were slightly increased in patients with canagliflozin treatment (amputation: OR = 1.60, 95% CI 1.04 to 2.46; PAD: OR = 1.53, 95 % CI 1.14 to 2.05). Meta-regression analyses indicated that greater weight reduction in SGLT2i users was significantly associated with the increased risks of amputation (ß = - 0.461, 95% CI - 0.726 to - 0.197), PAD (ß = - 0.359, 95% CI - 0.545 to - 0.172) and DF (ß = - 0.476, 95% CI - 0.836 to - 0.116). Lower baseline diastolic blood pressure (ß = - 0.528, 95% CI - 0.852 to - 0.205), more systolic blood pressure reduction (ß = - 0.207, 95% CI - 0.390 to - 0.023) and more diastolic blood pressure reduction (ß = - 0.312, 95% CI - 0.610 to - 0.015) were significantly associated with the increased risks of amputation, PAD and DF respectively in patients with SGLT2i treatment. CONCLUSIONS: The risks of amputation and PAD were slightly increased in patients with canagliflozin treatment. Reductions in body weight and blood pressure were associated with lower limb complications in patients with SGLT2i treatment.

The Biological Disease-Modifying Antirheumatic Drugs and the Risk of Cardiovascular Events: A Systematic Review and Meta-Analysis.

OBJECTIVE: To assess the association between the use of biological disease-modifying antirheumatic drugs (bDMARDs) and the risk of cardiovascular events in patients with systemic inflammatory conditions. METHODS: Eligible cohort studies or randomized controlled trials (RCTs) from inception to January 2021 were included. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) for cardiovascular outcomes were calculated in the fixed- and random-effects model accordingly. Associated factors with risks of cardiovascular events were also studied in sensitivity analyses and metaregression analyses. RESULTS: Compared with non-bDMARD users, the risks of myocardial infarction (MI) (OR = 0.74, 95% CI, 0.63 to 0.87), heart failure (OR = 0.84, 95% CI, 0.74 to 0.95), cardiovascular (CV) death (OR = 0.62, 95% CI, 0.40 to 0.95), all-cause mortality (OR = 0.64, 95% CI, 0.58 to 0.70), and 3P-MACE (composite endpoint of MI, stroke, and CV death) (OR = 0.69, 95% CI, 0.53 to 0.89) were significantly reduced in bDMARD users, which were mainly driven by the risk reduction in patients with rheumatoid arthritis (RA). TNF-α inhibitors exhibited consistent benefits in reducing the risks of MI, heart failure, CV death, all-cause mortality, and 3P-MACE. Moreover, the risks of heart failure, CV death, all-cause mortality, and 3P-MACE were significantly reduced in bDMARD users with follow-up over one year. CONCLUSIONS: The use of bDMARDs might be associated with the reduced risks of CV events, especially in patients with RA. The CV events might be less frequent in bDMARD users with TNF-α inhibitors or follow-up over one year. More investigations are needed to validate conclusions.

Causal relationship between gut microbiota and autoimmune thyroiditis: A mendelian study.

Background: Autoimmune thyroiditis (AIT), also known as Hashimoto's thyroiditis (HT) or chronic lymphocytic thyroiditis, is a prevalent autoimmune disorder. Despite its high prevalence, the pathogenesis of AIT remains unclear. Previous studies have suggested a potential association between gut microbiota and AIT. However, whether this relationship is causal or coincidental remains uncertain. To address this gap in knowledge, our study aimed to investigate the potential causal association between gut microbiota and AIT using the two-sample Mendelian randomization (MR) method. Methods: Summary-level gut microbiota data comprising 211 taxa (131 genera, 35 families, 20 orders, 16 classes, and 9 phyla) were obtained from the comprehensive MiBioGen study. Genetic associations with 22 gastrointestinal diseases were extracted from the UK Biobank, FinnGen study, and various extensive GWAS studies. A meticulous MR analysis was conducted to evaluate the causal relationship between genetically predicted gut microbiota and these gastrointestinal diseases. Sensitivity analyses and tests for heterogeneity were systematically performed to validate the reliability of our findings. Results: Six gut microbiota species showed significant associations with AIT according to the IVW method. Among them, the following exhibited negative associations with AIT: family Alcaligenaceae, family Pasteurellaceae (ID: 3689), family Peptococcaceae, genus Lachnospira, genus Victivallis, and order Pasteurellales (ID: 3688). No evidence of pleiotropy or heterogeneity was detected. Conclusion: The MR analysis uncovered a causal relationship at the genetic prediction level between specific gut microbiota and AIT. These findings offer novel insights into the mechanisms governing the development of AIT mediated by gut microbiota. This knowledge could inform the design of future interventions, potentially involving microbiome-related strategies, to address the mechanisms associated with AIT development.

Comparative analysis of two-hour creatinine clearance and the C-G formula for renal function assessment in critically ill patients.

Objective and rationale: To investigate if the 2-h creatinine clearance (Ccr2) provides a more precise and timely assessment of renal function in critically ill patients compared to the Cockcroft-Gault formula (CrC-G). Materials and methods: This cohort study incorporated 74 patients who were hospitalized for more than 48 h in the Intensive Care Unit over 6 months. A 24-h urine collection protocol was observed, and concurrently, 316 2-h urine specimens were obtained. Then calculated and analyzed the correlation and consistency between Ccr2, CrC-G, and 24-h creatinine clearance (Ccr24) values. The rates of change in Ccr2(ΔCcr2) and CrC-G(ΔCrC-G) were compared over two consecutive samples. Results: The R-values of Ccr2 and Ccr24 in the early, middle and late 24 h were 0.640, 0.886 and 0.854 (P < 0.001), with biases of -2.1, 1.7, and 6.3 ml/min/1.73 m2, respectively. Meanwhile, the R-values for CrC-G and Ccr24 at these time points were 0.618, 0.822, and 0.828(P < 0.001), with biases of -14.0, -5.2, and -1.8 ml/min/1.73 m2, respectively. For patients with Ccr24≥60 ml/min/1.73 m2, the R-value of Ccr2 and Ccr24 during the middle 2 h was 0.852(P < 0.001), while the R-values for CrC-G and Ccr24 were 0.763(P < 0.001), with biases of -2.3 ml/min/1.73 m2 and -14.2 ml/min/1.73 m2 respectively. For the group with Ccr24 ≥ 120 ml/min/1.73 m2 (n = 72), both Ccr2 and Ccr24 displayed a statistically significant elevation compared to CrC-G (P < 0.001), yet no significant difference was observed between Ccr2 and Ccr24 (P = 0.289). Out of 50 patients, 46(92 %) experienced a ΔCcr2≥20 % at least once, compared to 20(40 %) with a ΔCrC-G≥20 %(P < 0.001). 25(50 %) with a ΔCcr2≥50 %, compared to 3(6 %) with a ΔCrC-G≥50 %(P < 0.001). Conclusion: Ccr2 demonstrates a more accurate and more timely indicator of renal function in critically ill patients than CrC-G.

A Random Particle Swarm Optimization Based on Cosine Similarity for Global Optimization and Classification Problems.

In today's fast-paced and ever-changing environment, the need for algorithms with enhanced global optimization capability has become increasingly crucial due to the emergence of a wide range of optimization problems. To tackle this issue, we present a new algorithm called Random Particle Swarm Optimization (RPSO) based on cosine similarity. RPSO is evaluated using both the IEEE Congress on Evolutionary Computation (CEC) 2022 test dataset and Convolutional Neural Network (CNN) classification experiments. The RPSO algorithm builds upon the traditional PSO algorithm by incorporating several key enhancements. Firstly, the parameter selection is adapted and a mechanism called Random Contrastive Interaction (RCI) is introduced. This mechanism fosters information exchange among particles, thereby improving the ability of the algorithm to explore the search space more effectively. Secondly, quadratic interpolation (QI) is incorporated to boost the local search efficiency of the algorithm. RPSO utilizes cosine similarity for the selection of both QI and RCI, dynamically updating population information to steer the algorithm towards optimal solutions. In the evaluation using the CEC 2022 test dataset, RPSO is compared with recent variations of Particle Swarm Optimization (PSO) and top algorithms in the CEC community. The results highlight the strong competitiveness and advantages of RPSO, validating its effectiveness in tackling global optimization tasks. Additionally, in the classification experiments with optimizing CNNs for medical images, RPSO demonstrated stability and accuracy comparable to other algorithms and variants. This further confirms the value and utility of RPSO in improving the performance of CNN classification tasks.

Neuronal BST2: A Pruritic Mediator alongside Protease-Activated Receptor 2 in the IL-27-Driven Itch Pathway.

Chronic itch is a common and complex symptom often associated with skin diseases such as atopic dermatitis (AD). Although IL-27 is linked to AD, its role and clinical significance in itch remain undefined. We sought to investigate IL-27 function in itch using tissue-specific transgenic mice, various itch models, behavior scoring, RNA sequencing, and cytokine/kinase array. Our findings show that IL-27 receptors were overexpressed in human AD skin. Intradermal IL-27 injection failed to directly induce itch in mice but upregulated skin protease-activated receptor 2 (PAR2) transcripts, a key factor in itch and AD. IL-27 activated human keratinocytes, increasing PAR2 transcription and activity. Coinjection of SLIGRL (PAR2 agonist) and IL-27 in mice heightened PAR2-mediated itch. In addition, IL-27 boosted BST2 transcription in sensory neurons and keratinocytes. BST2 was upregulated in AD skin, and its injection in mice induced itch-like response. BST2 colocalized with sensory nerve branches in AD skin from both human and murine models. Sensory neurons released BST2, and mice with sensory neuron-specific BST2 knockout displayed reduced itch responses. Overall, this study provides evidence that skin IL-27/PAR2 and neuronal IL-27/BST2 axes are implicated in cutaneous inflammation and pruritus. The discovery of neuronal BST2 in pruritus shed light on BST2 in the itch cascade.

Anti-inflammatory therapies were associated with reduced risk of myocardial infarction in patients with established cardiovascular disease or high cardiovascular risks: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND AIMS: We aimed to evaluate the association between anti-inflammatory therapies and the incidence of cardiovascular events in patients with established cardiovascular disease (CVD) or high cardiovascular risks. METHODS: Literature retrieval was conducted in PubMed, Medline, Embase, the Cochrane Central Register of Controlled Trials and Clinicaltrial.gov website from the inception to December 2022. Randomized controlled trials comparing anti-inflammatory therapies with placebo in patients with established CVD or high cardiovascular risks were included. The results of the meta-analysis were computed as the risk ratio (RR) with 95% confidence interval (CI). RESULTS: Compared with placebo, anti-inflammatory therapies were associated with decreased incidence of myocardial infarction (MI) (RR = 0.93, 95% CI, 0.88 to 0.98), which was mainly driven by therapies targeting central IL-6 signaling pathway (RR = 0.83, 95% CI, 0.74 to 0.93). IL-1 inhibitors treatment was associated with reduced risks of heart failure (RR = 0.38, 95% CI, 0.18 to 0.80) while lower incidence of stroke was observed in patients with colchicine treatment (RR = 0.47, 95% CI, 0.28 to 0.77). MI events were less frequent in patients over 65 years of age (RR = 0.90, 95% CI, 0.83 to 0.98) or with follow-up duration over 1 year (RR = 0.90, 95% CI, 0.85 to 0.96) when comparing anti-inflammatory therapies with placebo. CONCLUSIONS: Anti-inflammatory therapies, especially those targeting the central IL-6 signaling pathway, may serve as promising treating strategies to ameliorate the risk of MI. IL-1 inhibitor and colchicine were associated with decreased risks of heart failure and stroke, respectively. MI risk reduction by anti-inflammatory therapies seemed to be more prominent in older patients with long follow-up duration.

Baseline eGFR, albuminuria and renal outcomes in patients with SGLT2 inhibitor treatment: an updated meta-analysis.

AIMS: To elucidate the association between baseline renal characteristics and the disparities in renal outcomes among patients with SGLT2i treatment. METHODS: Pubmed, Medline, Embase, the Cochrane Central Register of Controlled Trials and Clinicaltrial.gov were searched from inception to November 2022. Event-driven randomized controlled trials of SGLT2i with reports of renal outcomes were included. Sensitivity analyses of prespecified eGFR and UACR subgroups were conducted. RESULTS: Generally, compared with placebo, the use of SGLT2i was associated with improved renal prognosis (HR = 0.64, 95%CI 0.59-0.70). The magnitude of risk reductions in composite renal outcomes between SGLT2i versus placebo was comparable among different eGFR stratifications (normal renal function: HR = 0.49, 95%CI 0.31-0.79; mild renal impairment: HR = 0.57, 95%CI 0.48-0.68; moderate renal impairment: HR = 0.70, 95%CI 0.63-0.78; severe renal impairment: HR = 0.72, 95%CI 0.62-0.84; P for subgroup difference = 0.09). However, renal benefits seemd to be more prominent in normal to mildly increased albuminuria stratum (HR = 0.51, 95%CI 0.39-0.66) and severely increased albuminuria stratum (HR = 0.57, 95%CI 0.47-0.68), when compared with moderately increased albuminuria stratum (HR = 0.79, 95%CI 0.65-0.96; P for subgroup difference = 0.01). CONCLUSIONS: Generally, the use of SGLT2i was consistently associated with decreased risk of renal events in all prespecified eGFR and albuminuria spectrums, even in patients with substantial renal impairment. The renal benefits of SGLT2i seemed to be independent of baseline eGFR, while the risk reduction in renal events was more profound among patients with mildly increased albuminuria or severely increased albuminuria.

The correlations between steady-state concentration, duration of action and molecular weight of GLP-1RAs and their efficacy and gastrointestinal side effects in patients with type 2 diabetes mellitus: a systematic review and meta-analysis.

BACKGROUND: To assess the influence of steady-state concentration, duration of action and molecular weight of glucagon-like peptide-1 receptor (GLP-1RA) on efficacy and gastrointestinal (GI) side effects in patients with type 2 diabetes mellitus (T2DM). METHODS: PubMed, EMBASE, the Cochrane Center Register of Controlled Trials for Studies and Clinicaltrial.gov were searched from inception to April 2022. Randomized controlled trials (RCTs) comparing GLP-1RA versus non-GLP-1RA agents in patients with T2DM were included. Sensitivity analyses on steady-state concentration, duration of action and molecular weight of GLP-1RA were conducted. RESULTS: 113 RCTs were included. Greater HbA1c reduction between GLP-1RA users versus non-GLP-1RA users was observed in the high-steady-state-concentration stratum and long-acting stratum compared with the low-steady-state-concentration stratum (Psubgroup difference = 0.0004) and short-acting stratum (Psubgroup difference<0.0001). The risk of GI adverse events in GLP-1RA users versus non-GLP-1RA users was decreased in the high-steady-state-concentration stratum, long-acting stratum and heavy-molecular-weight stratum compared with low-steady-state-concentration stratum (Psubgroup difference<0.0001), short-acting stratum (Psubgroup difference = 0.002) and light-molecular-weight stratum (Psubgroup difference = 0.0008). CONCLUSION: GLP-1RA with high steady-state concentration and long duration of action showed better hypoglycemic effect. GLP-1RA with high steady-state concentration, long duration of action and heavy molecular weight was associated with lower risk of GI adverse events.

Global Trends of Gastrointestinal Endoscopy Anesthesia/Sedation: A Bibliometric Study (from 2001 to 2022).

Background: Gastrointestinal (GI) endoscopy becomes more and more common now in order to diagnose and treat GI diseases, and anesthesia/sedation plays an important role. We aim to discuss the developmental trends and evaluate the research hotspots using bibliometric methods for GI endoscopy anesthesia/sedation in the past two decades. Methods: The original and review articles published from 2001 to December 2022 related to GI endoscopy anesthesia/sedation were extracted from the Web of Science database. Four different softwares (CiteSpace, VOSviewer, and Bibliometrix, Online Analysis Platform of Literature Metrology (Bibliometric)) were used for this comprehensive analysis. Results: According to our retrieval strategy, we found a total of 3154 related literatures. Original research articles were 2855, and reviews were 299. There has been a substantial increase in the research on GI endoscopy anesthesia/sedation in recent 22 years. These publications have been cited 66,418 times, with a mean of 21.04 citations per publication. The US maintained a leading position in global research, with the largest number of publications (29.94%), and China ranked second (19.92%). Keyword burst and concurrence showed that conscious sedation, colonoscopy and midazolam were the most frequently occurring keywords. Conclusion: Our research found that GI endoscopy anesthesia/sedation was in a period of rapid development and demonstrated the improvement of medical instruments and surgical options that had significantly contributed to the field of GI endoscopy anesthesia/sedation. The US dominates this field, and the selection and dosage of sedative regimens have always been the foci of disease research to improve comfort and safety, while adverse events and risks arouse attention gradually. In the past 20 years, hotspots mainly focus on upper gastrointestinal endoscopy, gastroscopy, and esophagogastroduodenoscopy. These data would provide future directions for clinicians and researchers regarding GI endoscopy anesthesia/sedation.

Is the steady-state concentration, duration of action, or molecular weight of GLP-1RA associated with cardiovascular and renal outcomes in type 2 diabetes?

IMPORTANCE: Disparities were found in the cardiovascular and renal outcomes among different glucagon-like peptide 1 receptor agonist (GLP-1RA) subtypes. However, whether the characteristics of GLP-1RA itself are associated with these disparities remains unclear. OBJECTIVE: To assess the association between the steady-state concentration, duration of action, or molecular weight of GLP-1RA and the risks of cardiovascular and renal outcomes in patients with type 2 diabetes (T2D). DATA SOURCES: PubMed, MEDLINE, EMBASE, Cochrane and Clinicaltrial.gov from inception to April 2022. STUDY SELECTION: Randomized controlled trials (RCTs) investigating GLP-1RAs in patients with T2D were included. DATA EXTRACTION AND SYNTHESIS: Literature screening and data extraction were performed independently by 2 researchers. The outcomes were computed as odds ratio (OR) and its 95% confidence interval (CI). Subgroup analyses were conducted according to steady-state concentration, duration of action and molecular weight of GLP-1RAs. MAIN OUTCOMES AND MEASURES: Primary outcomes were major adverse cardiovascular events (MACE), composite renal outcome and all-cause mortality. RESULTS: In all, 61 RCTs were included. When compared with non-GLP-1RA agents, GLP-1RAs with high steady-state concentration were associated with greater risk reduction in MACE (p for subgroup difference = 0.01) and the composite renal outcome (p for subgroup difference = 0.008) in patients with T2D. Greater risk reductions in MACE between GLP-1RA users versus non-GLP-RA users were observed in long acting stratum when compared with short acting stratum (p for subgroup difference = 0.04) in patients with T2D. The molecular weight of GLP-1RAs was not associated with the risk of cardiovascular and renal outcomes. CONCLUSIONS AND RELEVANCE: GLP-1RAs with high steady-state concentrations might be associated with greater risk reductions in cardiovascular and renal outcomes in patients with T2D. Long acting GLP-1RAs might outperform short acting ones in reducing the risk of cardiovascular outcomes. These findings provided new insights for guiding the clinical applications of GLP-1RAs in patients with T2D.

Assessment of ovarian reserve in patients with type 1 diabetes: a systematic review and meta-analysis.

PURPOSE: Current knowledge about the ovarian reserve in patients with type 1 diabetes is inconsistent and based on studies with small sample size. This meta-analysis aimed to produce a comprehensive evaluation on the ovarian reserve of type 1 diabetes female patients and to analyze the associated factors with the ovarian reserve. METHODS: Systematic searches were conducted for studies published from the inception to December 2021. Original human observational studies either with case-control, cross-sectional, or longitudinal design evaluating ovarian reserve markers between type 1 diabetes patients and healthy controls were included. Levels of anti-müllerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol (E2) were extracted. RESULTS: It was indicated that women with type 1 diabetes were associated with decreased levels of AMH compared with healthy controls (weighted mean difference [WMD] -0.70 ng/ml, 95% confidence intervals [CI] -1.05 to -0.34 ng/ml, P = 0.0001). Subgroup analyses stratified by age showed that adult patients with type 1 diabetes were associated with decreased levels of AMH (WMD -0.70 ng/ml, 95% CI -1.06 to -0.34 ng/ml, P = 0.0001) and FSH (WMD -1.07 IU/L, 95% CI -1.75 to -0.39 IU/L, P = 0.002) compared with healthy controls. Meta-regression analysis showed no significant correlation between AMH, FSH, and clinical factors, while level of E2 was negatively correlated with daily insulin doses and glycosylated hemoglobin A1c (HbA1c) values. CONCLUSION: According to this meta-analysis, type 1 diabetes might be associated with decreased AMH levels. Further studies using different markers and fertility outcomes focus on the ovarian reserve of women with type 1 diabetes are urgently needed.

Disparities in efficacy and safety of sodium-glucose cotransporter 2 inhibitor among patients with different extents of renal dysfunction: A systematic review and meta-analysis of randomized controlled trials.

Background: The pleiotropic efficacy of SGLT2is in patients with different eGFR levels has not been well-understood. This systematic review and meta-analysis assessed the disparities in the efficacy and safety of SGLT2i treatment across stratified renal function. Methods: We searched four databases from inception to December 2021. We included randomized controlled trials (RCTs) with reported baseline eGFR levels and absolute changes from baseline in at least one of the following outcomes: HbA1c, body weight, blood pressure, and eGFR. Continuous outcomes were evaluated as the weighted mean differences (WMDs) and 95% confidence intervals (CIs). Categorical outcomes were evaluated as odds ratios (ORs) and accompanying 95% CIs. Results: In total, 86 eligible RCTs were included. SGLT2is produces a substantial benefit in glycemic control, weight control, and blood pressure control even in patients with impaired renal function. HbA1c and weight reductions observed in SGLT2i users were generally parallel with the renal function levels, although there was an augmented weight reduction in severe renal dysfunction stratum [HbA1c: -0.49% (-0.58 to -0.39%) for normal renal function, -0.58% (-0.66 to -0.50%) for mild renal function impairment, -0.22% (-0.35 to -0.09%) for moderate renal function impairment, and -0.13% (-0.67 to 0.42%) for severe renal function impairment (p < 0.001 for subgroup differences); weight: -2.12 kg (-2.66 to -1.59 kg) for normal renal function, -2.06 kg (-2.31 to -1.82 kg) for mild renal function impairment; -1.23 kg (-1.59 to -0.86 kg) for moderate renal function impairment; -1.88 kg (-3.04 to -0.72 kg) for severe renal function impairment (p = 0.002 for subgroup differences)]. However, the blood pressure reduction observed in SGLT2i users was independent of renal function. When compared with the placebo, the occurrence of hypoglycemia was more frequent in patients with favorable renal function rather than in those with substantial renal dysfunction. Conclusion: The HbA1c and body weight reductions observed in SGLT2i users were generally parallel with their baseline eGFR levels, while blood pressure reductions in SGLT2i users were independent of their baseline eGFR levels. Consistently, when compared with the placebo, hypoglycemia was more frequent in patients with favorable renal function, where the HbA1c reduction was profound.

The association between the use of sodium glucose cotransporter 2 inhibitor and the risk of diabetic retinopathy and other eye disorders: a systematic review and meta-analysis.

OBJECTIVE: To assess the association between the use of sodium-glucose cotransporter 2 inhibitor (SGLT2i) and the incidence of diabetic retinopathy (DR). RESEARCH DESIGN AND METHODS: PubMed, Medline, Embase, the Cochrane Central Register of Controlled Trials, and Clinicaltrial.gov were searched from inception to October 2021. Randomized controlled trials (RCTs) with reports of incidence of DR and other eye disorders between SGLT2i and non-SGLT2i users with type 2 diabetes mellitus were included. RESULTS: In general, the incidences of DR were comparable between SGLT2i and non-SGLT2i users (OR = 0.80, 95%CI 0.61 to 1.06, P = 0.12). However, compared with non-SGLT2i users, the incidence of DR was significantly reduced in SGLT2i users with diabetes duration less than 10 years (OR = 0.32, 95%CI 0.13 to 0.76, P = 0.01). Weight reduction in SGLT2i users was associated with a decreased risk of retinal detachment. Moreover, longer study duration was associated with lower incidence of cataract and retinal vasculopathy in SGLT2i users. CONCLUSIONS: In general, the use of SGLT2i was not associated with the incidence of DR. However, a reduced risk of DR was observed in SGLT2i users with diabetes duration less than 10 years. An early initiation of SGLT2i might be more likely to provide with ocular benefits.
