Abstract 4134873: Olezarsen for Hypertriglyceridemia in Patients at High Cardiovascular Risk - A Systematic Review and Meta Analysis

Background: Hypertriglyceridemia, a common lipid disorder linked to increased risks of cardiovascular diseases and metabolic syndrome, remains a global health challenge. Traditional treatments, though widely used, often have limited efficacy and adverse effects. Olezarsen, a novel antisense oligonucleotide, targets apolipoprotein C-III and shows promise in significantly reducing triglyceride levels. Aim: To conduct a meta-analysis comparing Olezarsen with placebo in patients with hypertriglyceridemia. Methods: We performed an extensive literature search of PubMed, EMBASE, and Cochrane Library databases up to May 2024 to identify studies comparing Olezarsen and placebo in patients with hypertriglyceridemia, irrespective of comorbid cardiovascular disease. Effect estimates were pooled using a random-effects model and reported as risk ratios (RR) for dichotomous outcomes and standard mean differences (SMD) for continuous outcomes, with 95% confidence intervals (CIs) for each. Results: Three randomized controlled trials (RCTs) with a total of 334 participants were included. Olezarsen significantly reduced triglyceride levels at 6 months (SMD: -1.69; 95% CI -2.22 to -1.17; P < 0.00001; Figure ) and 12 months (SMD: -1.64; 95% CI -2.22 to -1.07; P < 0.00001; Figure ). VLDL levels also decreased at 6 months (SMD: -1.95; 95% CI -2.38 to -1.51; P < 0.00001) and 12 months (SMD: -0.83; 95% CI -1.13 to -0.53; P < 0.00001). Lipid profile improvements included reductions in total cholesterol, non-HDL cholesterol, and apoB levels, with increases in HDL cholesterol and apoA-1. Adverse events were comparable between Olezarsen and placebo, although serious adverse events were significantly higher in the Olezarsen group (RR: 2.55; 95% CI 1.17 to 5.58; p = 0.02). Conclusion: Olezarsen demonstrates significant efficacy in reducing triglyceride and VLDL levels while improving overall lipid profiles in hypertriglyceridemia patients. Despite higher rates of serious adverse events, its overall safety profile remains acceptable.

Abstract 4120898: Assessment of Subclinical Atherosclerosis in Psoriasis Patients Using Echocardiographic Coronary Flow Parameters: A Systematic Review and Meta-Analysis

Background: Chronic inflammatory diseases are associated with a higher risk for atherosclerosis and adverse cardiovascular events. Psoriasis is a systemic inflammatory condition that significantly increases coronary artery disease risk. Subclinical atherosclerosis can be estimated by echocardiographic parameters like coronary flow velocity reserve (CFVR), diastolic peak flow velocity (DPFV), and hyperemic DPFV. Limited literature investigates these parameters in psoriasis, with inconsistent results. Methods: We systematically searched the major bibliographic databases including PubMed, Embase, Cochrane Library, and Google Scholar from inception to 7th May 2024 to retrieve relevant studies. The outcomes were pooled using the inverse variance random-effects model, and the results were presented as standardized mean difference (SMD) with the corresponding 95% confidence interval (CI). Results: 4 studies with 557 participants (281: psoriasis and 276: controls) were included. The mean age of the psoriasis group was 44.7 ± 7.7 years and of the control group was 45.2 ± 5.9 years. Psoriasis patients had a significantly lower CFVR [SMD: -0.71; 95% CI: -0.97, -0.45; p<0.00001] and hyperemic DPFV [SMD: -0.71; 95% CI: -1.30, -0.12; p=0.02] compared to healthy controls. However, the difference between baseline DPFV was insignificant between the two groups [SMD: 0.20; 95% CI: -0.92, 1.32; p=0.73]. Conclusion: This study demonstrates that psoriasis is associated with coronary microvascular disease as measured by significantly lower CFVR and hyperemic DPFV. These results suggest that impaired myocardial perfusion in psoriasis patients may be an early manifestation of cardiac involvement. Hence, early risk stratification in psoriasis patients is crucial. Further large, randomized trials are essential to corroborate the results of this meta-analysis.

The influence of physical exercise on negative emotions in adolescents: a meta-analysis

BackgroundAdolescence is also accompanied by ongoing mood changes (relative to childhood and adulthood), which can trigger more extreme negative emotional responses. Physical exercise alleviates negative emotions and reduces the risk of mental illness. However, the effect of physical exercise on negative emotions in adolescents is unclear, so it is valuable to synthesize previous studies with meta-analysis.ObjectiveTo examine the influence of physical exercise (PE) intervention on negative emotions in adolescents aged 10 to 19 years.MethodsWe retrieved the articles from PubMed, Web of Science, EBSCO, Cochrane, and Embase up to April 11, 2024. The main search terms were physical exercise, negative emotions, adolescents, randomized controlled trials. The meta-analysis was conducted using Review Manager 5.3. A random-effects model was employed to calculate the standardized mean difference (SMD) and 95% confidence interval (CI). Subgroups were analysed as the type of negative emotions, type of control group, intervention type, duration, time, frequency.ResultsThe PE intervention group exhibited a significantly superior improvement in alleviating negative emotions compared to the control group (SMD = -0.59, 95% CI: -0.92 to -0.26, p < 0.01, Z = 3.50, I² = 95%). PE was particularly effective in mitigating adolescent depression (SMD = -0.67, 95% CI = -1.07 to -0.28, p < 0.01, I² = 96%) but did not yield significant results in reducing adolescent anxiety (SMD = -0.29, 95% CI = -0.63 to 0.05, p = 0.10, I² = 95%).ConclusionPE intervention can ameliorate negative emotions in adolescents.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42024534375.

Abstract 4120912: Non-Alcoholic Fatty Liver Disease is Associated with Coronary Flow Reserve Impairment: A Pilot Meta-Analysis

Background: Non-alcoholic fatty liver disease (NAFLD) is estimated to affect approximately 25% of the global population. Significant epidemiological data links NAFLD to an increased risk of coronary artery disease. Both, coronary artery disease and NAFLD are linked to underlying insulin resistance and inflammation as drivers of the disease. Coronary flow reserve parameters including coronary flow reserve velocity (CFRV), baseline diastolic peak flow velocity (DPFV), and hyperemic DPFV are non-invasive markers of coronary microvascular circulation. The existing literature contains conflicting findings for these parameters in NAFLD patients. Aim: This meta-analysis aimed to compare CFRV, baseline DPFV, and hyperemic DPFV in between NAFLD patients and healthy controls. Methods: A comprehensive systematic search was conducted on PubMed, Embase, Cochrane Library, and Google Scholar from inception until 8th May 2024 to identify relevant studies. We pooled the standardized mean differences (SMD) with the 95% confidence intervals (CI) using the inverse variance random-effects model. A p-value of less than 0.05 was considered statistically significant. Results: We included 4 studies with 1139 participants (226: NAFLD and 913: controls). The mean age in the NAFLD group was 54.55 ± 7.62 years and in the control group was 54.2 ± 7.6 years. NAFLD was associated with a significantly lower CFRV [SMD: -0.77; 95% CI: -1.19, -0.36; p<0.0002] and hyperemic DPFV [SMD: -0.73; 95% CI: -1.03, -0.44; p<0.00001] compared to the controls. NAFLD demonstrated a statistically insignificant trend towards reduction in the baseline DPFV [SMD: -0.09; 95% CI: -0.38, 0.19; p=0.52] as compared to healthy controls. Conclusion: NAFLD patients are at a higher risk of coronary microvascular dysfunction as demonstrated by reduced CFRV and hyperemic DPFV. The presence of abnormal coronary flow reserve in NAFLD patients provides insights into the higher rates of cardiovascular disease in these patients. Early aggressive targeted interventions towards impaired coronary flow reserve in NAFLD subjects may lead to improvement in clinical outcomes.

Abstract 4136561: Music therapy for postprocedural pain in patients undergoing cardiac surgery: a meta-analysis of randomized controlled trials

Background: Patients undergoing cardiac surgeries often experience significant levels of pain and anxiety, which can impair effective recovery. Music therapy has been proposed as a non-pharmacological intervention to alleviate these symptoms. This meta-analysis aimed to evaluate the effectiveness of music therapy in patients undergoing cardiac surgeries. Methods: We systematically searched PubMed, Embase, and Cochrane databases for randomized controlled trials (RCTs) analyzing music therapy in patients undergoing cardiac surgeries. We pooled mean differences (MD), and standardized mean differences (SMD) for continuous outcomes with 95% confidence intervals (CI) with a random-effects model. We performed a trial sequential analysis (TSA) to assess the random risk of pain, and conducted a subgroup analysis to compare heart and respiratory rate between children and adults. We used R version 4.3.2 and TSA version 0.9.5.10 for statistical analyses. Results: Our meta-analysis included 20 RCTs comprising 1379 patients, of whom 715 (51.9%) were randomized to music therapy. Compared with control, music significantly reduced postoperative pain (SMD -0.59; 95% CI: -0.76 to -0.41; p<0.05; Figure A), and anxiety (SMD -0.59; 95% CI: -0.74 to -0.44; p<0.05; Figure B). There was a significant difference between groups in heart rate (MD -5.68 bpm; 95% CI: -9.73 to -1.63; p<0.05), overall there was an important subgroup interaction between children and adults (p=0.01). In children, music therapy reduced the respiratory rate (MD -5.98 ipm; 95% CI: -6.71 to -5.25) compared to control, whereas in adults, no significant differences were observed among these groups, overall, there was a significant subgroup interaction (p<0.01). For the primary endpoint, TSA suggested a low risk of type 1 error, therefore these results may be conclusive. Conclusion: In patients undergoing cardiac surgery, music therapy reduced postoperative pain, anxiety, heart rate, and respiratory rate.

Abstract 4145880: Incidence and Outcomes of Acute Myocardial Infarction (AMI) in Hematological Malignancy Patients: Systematic review and Meta-analysis

Background: Patients with hematological malignancies may face increased cardiovascular risks, including acute myocardial infarction (AMI). This systematic review and meta-analysis aims to evaluate the incidence and outcomes of AMI in patients with hematological malignancies compared with the general population. Methods: A comprehensive literature search was conducted using the PubMed, Embase, and Google Scholar databases. Random effect models were utilized to calculate Mantel-Haenszel odds ratios (ORs) with 95% confidence intervals (CIs). The inverse variance method with DerSimonian–Laird (DL) of Tau2 was used to calculate standardized mean differences (SMDs) with CIs. Statistical significance was set at p < 0.05. The primary endpoint was the incidence of AMI, while secondary outcomes included in-hospital mortality, length of hospital stay, likelihood of undergoing invasive procedures, total hospital costs, bleeding events, and stroke outcomes. Results: Twenty-six articles, including approximately 6.33 million patients with hematological malignancies, were included in the meta-analysis. Hematological malignancies were not associated with an increased incidence of AMI compared with the general population (OR = 0.91; 95% CI 0.80 to 1.03; p<0.001). AMI in hematological malignancies was associated with an increased risk of in-hospital mortality (OR = 1.71; 95% CI 1.57 to 1.86; p<0.001), bleeding event (OR = 1.30; 95% CI 1.12 to 1.60; p<0.001), and stroke (OR = 1.24; 95% CI 1.09 to 1.42) compared with AMI in the general population. Patients admitted due to AMI in hematologic malignancies also experienced an increased length of stay (SMD = 0.25; 95% CI 0.20 to 0.28; p<0.001) compared with AMI in the general population. There was no significant difference between the two groups in terms of the likelihood of undergoing invasive procedures (OR = 0.62; 95% CI 0.56 to 0.69) or total hospital expenditure (SMD = 0.09; 95% CI -0.01 to 0.19). Conclusion: While hematological malignancies do not appear to increase the incidence of acute myocardial infarction (AMI), patients who experience AMI episodes are at higher odds of in-hospital complications.

Systematic Review and Meta-Analysis of Sclerocarya birrea on Metabolic Disorders: Evidence from Preclinical Studies

Background/Objectives: Metabolic disorders, including diabetes, obesity, and cardiovascular diseases, are significant global health issues. Nutraceuticals, such as Sclerocarya birrea (SB), known for its high polyphenol content, are increasingly explored for managing these conditions. This study aims to evaluate the antihyperglycemic, hypolipidemic, and antihypertensive effects of SB in animal models to understand its potential as a natural intervention for metabolic diseases. Methods: A systematic review and meta-analysis were conducted according to PRISMA guidelines. Searches across databases like PubMed, Web of Science, Embase, and Scopus identified studies using SB in animal models of metabolic disorders. Inclusion criteria were studies with SB intervention, control groups, and quantitative measures of metabolic parameters. The study was registered with INPLASY (INPLASY2024100031). Results: The meta-analysis revealed that SB significantly reduces blood glucose levels in diabetic animal models. Acute administration of SB showed a pooled standardized mean difference (SMD) of −7.13 (95% CI: −11.44 to −2.83) at 1 h and −9.75 (95% CI: −15.92 to −3.59) at 2–4 h post-administration. Chronic administration indicated a non-significant reduction in glucose levels (SMD: −5.69, 95% CI: −16.38 to 5.01). Conclusions: SB appears to have the potential for reducing blood glucose levels and may offer benefits for other cardiometabolic risk factors, including lipid profiles and oxidative stress. However, variability in the results underscores the need for further research, including standardized animal studies and clinical trials, to confirm these effects and clarify the mechanisms by which SB may impact metabolic disorders.

Abstract 4125729: Elevated Pre-Procedural Serum Natriuretic Peptide Levels Are Associated with All-Cause Mortality in Patients Undergoing Transcatheter Edge-to-Edge Mitral Valve Repair: A Systematic Review and Meta-Analysis

Background: Transcatheter edge-to-edge mitral valve repair (TEER) is an established procedure in patients with severe mitral regurgitation (MR) and elevated surgical risk on optimal medical therapy. However, there remains considerable mortality in this patient population. Some studies have shown that serum brain natriuretic peptide (BNP) and N-terminal pro b-type natriuretic peptide (NT-proBNP) predict all-cause mortality after TEER, whereas other studies have shown mortality to be independent of these markers. To address this gap in knowledge, we sought to examine the existing literature to determine whether there is an association between pre-procedural serum natriuretic peptides and mortality after TEER. Hypothesis: Among patients undergoing TEER, elevated pre-procedural BNP and NT-proBNP are associated with increased all-cause mortality. Methods: Databases including MEDLINE, Embase, and Cochrane Library were searched from inception through September 2023 for studies assessing pre-procedural serum natriuretic peptide levels and mortality among patients undergoing TEER. Pooled hazard ratios (HR) and standardized mean differences (SMD) were calculated using a random-effects model estimated by restricted maximum likelihood with the Hartung-Knapp modification. Results: A total of 30 studies comprising 10259 patients undergoing TEER met inclusion criteria. 25 studies measured NT-proBNP and 5 studies measured BNP. Elevated pre-procedural NT-proBNP (>5000 or >10000 pg/mL) was associated with increased all-cause mortality in both adjusted (HR = 2.94; 95% CI = 1.75 - 4.95; I2 = 46.8%) and unadjusted (HR = 5.16; 95% CI = 1.85 - 14.40; I2 = 0.0%) analyses (Figures 1 and 2). Pre-procedural BNP and NT-proBNP were also significantly lower among survivors at 12 months compared to non-survivors (SMD = 0.82; 95% CI = 0.37 - 1.27; I2 = 78.3%) (Figure 3). This association was demonstrated in patients with primary or secondary MR. Conclusions: Pre-procedural BNP and NT-proBNP levels are significant predictors of all-cause mortality in patients undergoing TEER for primary or secondary MR. This supports the inclusion of BNP or NT-proBNP in pre-procedural assessments to help inform patient discussions and guide post-procedural follow-up and monitoring.

Abstract 4138721: Outcomes of Coronary Revascularization in Patients with Contemporaneous Abdominal Organ Transplant

Background: Clinical evaluation surrounding liver and kidney transplantation may reveal obstructive coronary artery disease (CAD). However, little is known about outcomes after revascularization in this population. Our aim was to examine coronary artery bypass grafting (CABG) and percutaneous intervention (PCI) in peri-transplant patients compared to the general CABG/PCI populations. Methods: We conducted a matched retrospective cohort study between 2014-2022 at a single academic center. Matching was done by optimal full matching of a logistic regression-based propensity score adjusting for age, chronic kidney disease, diabetes, tobacco use, chronic lung disease, hypertension, prior myocardial infarction, and valvular disease. Covariate balance was assessed as standardized mean difference <0.2. The primary outcome was a composite of in-hospital death, stroke, and myocardial infarction, and a key secondary outcome was incident arrhythmia. Results: The study population comprised 2655 patients: 24 CABG/transplant (median age, 64 [IQR, 59-66]; 4 female [17%]), 1037 CABG/non-transplant (age, 66 [59-73]; 190 female [18%]), 27 PCI/transplant (age, 62 [IQR, 55-67]; 6 female [22%]), and 1567 PCI/non-transplant (age, 70 [IQR, 60-78]; 399 female [25%]). CABG/PCI preceded transplant by a median 321/324 days, respectively, and followed transplant by a median 461/36 days, respectively. For the primary outcome in CABG patients, there were no events in the transplant group and an estimated potential outcome in 6.5% of the matched non-transplant group (marginal RR, <0.001; p<0.001). For the primary outcome in PCI patients, there were no events in the transplant group and an estimated potential outcome in 2.4% of the matched non-transplant group (marginal RR, <0.001; p<0.001). For incident arrhythmia in CABG patients, the estimated potential outcome was 12% and 17.5% in the transplant and matched non-transplant groups, respectively (marginal RR, 0.98; 95% CI, 0.37-2.6; p=0.97). For incident arrhythmia in PCI patients, the estimated potential outcome was <0.001% and 3.6% in the transplant and matched non-transplant groups, respectively (marginal RR, 0.89; 95% CI, 0.12-6.5; p=0.91). Conclusions: Patients with contemporaneous abdominal organ transplant undergoing coronary revascularization suffered no in-hospital mortality, stroke, or myocardial infarction, and were not at greater risk of incident arrhythmia than similar non-transplant patients.

Abstract 4114372: Is Takotsubo syndrome associated with a favorable in-hospital outcome among patients with cardiogenic shock? A propensity score-matched analysis of the National Inpatient Sample Data (2016-2020)

Background: Takotsubo cardiomyopathy (TTC) is characterized by impaired left ventricular function due to typical, regional wall motion abnormalities in the absence of significant obstructive coronary artery disease. Previous small-sized retrospective studies reported favorable outcomes of cardiogenic shock in patients with TTC. We aimed to investigate whether the presence of TTC is associated with a favorable in-hospital outcome among patients admitted for cardiogenic shock using a large nationally representative dataset. Methods: Utilizing data from the National Inpatient Sample (NIS) spanning from 2016 to 2020, we identified patients admitted for cardiogenic shock using ICD-10 codes. Patients with TTC were also identified using ICD-10 codes. Using sociodemographic variables, and comorbid medical conditions, and performed procedures as matching variables, we conducted a 1:1 nearest-neighbor propensity score matching to mitigate potential confounders. The success of matching was evaluated based on standardized mean differences. In-hospital mortality was the primary outcome, while in-hospital complications, length of stay (LOS), and cost of hospitalization were secondary outcomes. We employed the Cochrane-Mantel-Haenszel method to assess the odds ratio (OR) for in-hospital mortality and complications. Simple linear regression models were used to evaluate differences in LOS and cost of hospitalization. Results: The final sample included 22,594 patients, evenly distributed between the groups with and without TTC. The mean age of the cohort was 65.4 years (SD = 15.9), with 74.7% being males. Ethnic composition indicated 75.7% Whites, 9.3% Blacks, and 8.1% Hispanics. The overall in-hospital mortality rate was 32.7%. The TTS group had a lower mortality rate (38.4% Vs 27%, p<0.001). Patients with TTC had lower odds of in-hospital mortality, cardiac arrest, ventricular tachycardia, and acute kidney injury. However, they were noted to have higher odds of deep vein thrombosis, stroke, slightly higher LOS, and cost of hospitalization. Conclusion: In summary, our study suggests that Takotsubo Cardiomyopathy is associated with significantly lower in-hospital mortality rates among patients admitted for cardiogenic shock, indicating a favorable prognosis in this clinical setting.

Meta-analysis of the effects of different exercise modes on cardiac function and peak oxygen uptake in patients with type 2 diabetes mellitus

BackgroundThe benefits of exercise for primary and secondary prevention of cardiovascular events have been reported in patients with type 2 diabetes mellitus (T2DM). However, the effects of exercise on cardiac structure and function require clarification.MethodsA literature search for clinical studies reporting on the effects of exercise on cardiac structure, cardiac function, and VO2peak in T2DM patients was conducted. PubMed, Embase, EBSCO, Web of Science, and China National Knowledge Infrastructure were systematically searched for original articles published from January 2000 to July 2023. The effect size was expressed as the mean difference (MD) or standardized mean difference (SMD) and its 95% confidence interval (CI). Subgroup analyses were performed by exercise mode (high-intensity interval training [HIIT] or moderate-intensity continuous training [MICT]) and intervention duration (>6 or ≤6 months).ResultsCompared to usual care, both HIIT and MICT significantly affected left ventricular end-diastolic volume (MD: 19.44, 95% CI: 13.72 to 25.17, p < 0.00001; I2 = 42%; MD: 13.90, 95% CI: 7.64 to 20.16, p < 0.0001; I2 = 0%), but only HIIT significantly affected left ventricular mass (MD: 17.04 g, 95% CI: 5.45 to 28.62, p = 0.004; I2 = 0%). HIIT significantly improved left ventricular ejection fraction (MD: 5.52, 95% CI: 2.31 to 8.73, p = 0.0008; I2 = 0%), as did MICT in the ≤6 months subgroup (MD: 1.36, 95% CI: 0.61 to 2.10, p = 0.0004; I2 = 0%). Neither significantly affected systolic tissue velocity. HIIT significantly improved VO2peak (MD: 8.04, 95% CI: 6.26 to 9.83, p < 0.00001; I2 = 0%), as did MICT in the ≤6 months subgroup (MD: 3.33, 95% CI: 2.39 to 4.27, p < 0.00001; I2 = 0%).ConclusionExercise significantly improved cardiac structure, systolic function, and VO2peak, but did not significantly affect diastolic function in T2DM patients. HIIT seemed to be superior to MICT at improving VO2peak and left ventricular ejection fraction in T2DM patients.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO/, PROSPERO registration no.: CRD4242018087376

Abstract 4131381: Comparison of Dietary Macronutrient Interventions for Weight and Cardiovascular Risk Factor Reduction: A Systematic Review and Network Meta-analysis of Randomized Controlled Trial

Background: Dietary interventions play a crucial role in weight management and reducing cardiovascular risk factors. Our study aims to compare the effectiveness of four dietary macronutrient interventions on weight loss and cardiovascular (CV) risk factor reduction through a systematic review and network meta-analysis. Methods: We conducted a comprehensive literature search on PubMed, Scopus, Embase, and Cochrane Library up till May 2024 to identify randomized controlled trials (RCTs) comparing four macronutrient dietary interventions including Mediterranean Diet (MD), Keto, Dietary Approaches to Stop Hypertension (DASH), and Intermittent Fasting (IF) with study period ≥ 6 months or 24 weeks. The primary outcomes of interest were weight loss, systolic blood pressure (SBP), Diastolic blood pressure (DBP), Body Mass Index (BMI), High density lipoprotein (HDL), Low density Lipoprotein (LDL), cholesterol levels and C-reactive protein (CRP) levels. Outcomes were reported as standard mean difference (SMD). Results: Our analysis identified 50 studies enrolling 5368 patients (MD=3554; DASH=838; Keto=206; IF=770). Regarding BP outcome, MD and DASH had significant reduction in SBP and DBP respectively (MD [SBP]: -0.76 mmHg vs DASH [DBP]: -1.92 mmHg) respectively. In contrast, IF showed a significant rise in SBP (0.87). MD participants also had significant weight loss (-1.06 kg) and a moderate decrease in BMI (-0.79) when compared with other diets. Furthermore, IF, keto, and MD showed moderate increase in HDL levels (0.61, 0.77 and 0.33) respectively. In contrast, DASH resulted in a moderate decline in HDL levels (-0.92). IF and MD resulted in modest decline in LDL levels (-0.45 and -0.42) respectively. In contrast, Keto demonstrated non-significant rise in LDL (0.35). DASH showed a significant decrease in triglycerides (-3.02). Lastly, MD demonstrated a significant reduction in CRP (-0.89). Conclusions: MD and DASH were superior to other dietary interventions in terms of weight loss and CV risk factors. Further research is required to tailor specific types of dietary interventions and assess their long-term efficacy on weight loss and CV risk reduction.

Effects of Non-Pharmacological Interventions on the Swallowing Function of Patients With Post-Stroke Dysphagia: A Systematic Review and Network Meta-Analysis.

Post-stroke dysphagia can lead to serious complications and appropriate rehabilitation can significantly improve swallowing function. However, the best rehabilitation method for post-stroke dysphagia patients is not clear at the present stage, so it is necessary to conduct a comprehensive network meta-analysis and systematic review of different interventions for dysphagia. To compare the effectiveness and ranking of different interventions for improving swallowing function, and feeding and daily function in patients with post-stroke dysphagia. Seven databases were searched from the date of inception to September 1, 2022. Two investigators independently conducted literature searches, selected randomized controlled trials on dysphagia interventions, and assessed study quality. Network meta-analysis was conducted by using Stata software. A total of 33 studies involving 1,341 patients were included. According to the ranking probabilities, acupuncture was rated as the most effective of all interventions to enhance patients' swallowing function (surface under cumulative ranking curve values [SUCRCV]: 99.0%, standardized mean difference [SMD]: -2.40, 95% confidence interval [CI]: -3.38 to -1.43), followed by the chin tuck against resistance exercise (CTAR, SUCRA: 89.9%, SMD: -1.83, 95% CI: -2.69 to -0.97). Among all the interventions, acupuncture was the most effective for feeding and daily function (SUCRCV: 88.4%, SMD: -1.62, 95% CI: -2.94 to -0.30). The results showed that acupuncture was the most effective in the rehabilitation of patients with post-stroke dysphagia, followed by CTAR. Considering that CTAR is a low-cost and highly feasible intervention, we suggest that CTAR should be selected as a rehabilitation measure for patients with post-stroke dysphagia to improve their swallowing function.

Examining Working Memory Training for Healthy Adults—A Second-Order Meta-Analysis

Background: Enhancing working memory performance in cognitively and physically healthy individuals is a popular area of research. The results from a large number of studies have now been summarized in multiple meta-analyses. In these reviews, various training methods have been examined, including mindfulness training, adaptive working memory training, physical activity training, and video game training, to examine whether working memory capacity can be improved. This report aggregated the results of these meta-analyses using second-order meta-analytic approaches to ascertain the extent to which working memory functioning can be enhanced in healthy adults. Methods: A total of six meta-analyses of randomized controlled trials that compared working memory interventions to a control group were included in the analyses. These studies were identified after systematically searching three electronic databases: APA PsycInfo, ERIC and Medline. Collectively, the meta-analyses investigated the effects of cognitive programs, mindfulness, video games and physical activity on working memory. Only meta-analyses undertaken with healthy adults aged between 18 and 55 years were included in the report. Results: The results revealed an average improvement in working memory across the included studies compared to the control groups. The findings indicated a small yet significant enhancement in working memory, with a standardized mean difference of 0.335 (95% CI [0.223; 0.447], p < .001). Further analysis tests for superiority effects between the different working memory training programs revealed no significant differences between intervention effect sizes. Conclusion: Based on the findings, it can be concluded that the working memory capacity of healthy adults can be improved through training. However, the effect size is small, so the utility of this type of training in real-life improvements in cognition may be minimal. The evidence does not indicate that one type of working memory training is superior to another.

Real-world evidence of effectiveness and safety of pasireotide in the treatment of acromegaly: a systematic review and meta-analysis.

Pasireotide long-acting release (PAS-LAR) is a second-generation somatostatin receptor ligand (SRL) approved for acromegaly treatment. This meta-analysis aimed to evaluate the real-world effectiveness and safety of PAS-LAR in patients with acromegaly resistant to first-generation somatostatin receptor ligands (fgSRL). A systematic literature search was conducted in PubMed and Web of Science for real-world studies on PAS-LAR in acromegaly published between 2014 and 2023. Random-effects meta-analyses were performed on biochemical control rates, tumor shrinkage, and metabolic parameters. Twelve studies comprising 409 patients were included. The pooled rate of insulin-like growth factor 1 (IGF-1) control was 57.9% [95% CI: 48.4-66.8] and the percentage of patients with tumor shrinkage was 33.3% [95%CI: 19.7-50.4]. Significant reductions were observed in growth hormone standardized mean difference (SMD) 0.6 ng/mL [95% CI: 0.3 to 1.0] and IGF-1 levels SMD 0.9 ULN [95% CI: 0.4 to 1.4]. However, as expected, a worsening in glucose metabolism was noted as an increase in fasting glucose SMD - 0.8mg/dL [95% CI: -1.0 to -0.5, p < 0.01], glycated hemoglobin SMD - 0.5% [95% CI: -0.7 to -0.2]. and type 2 diabetes mellitus prevalence SMD - 11.5% (95% CI: -17.5 to -5.5). PAS-LAR demonstrated higher effectiveness in real-world settings, with over 60% of patients achieving IGF-1 control compared to the around 30% efficacy observed in clinical trials. These findings suggest that PAS-LAR is an effective option for acromegaly patients resistant to fgSRL, but careful monitoring of glucose levels is essential. The high heterogeneity observed across studies emphasizes the need for identifying PAS-LAR response biomarkers to set-up individualized treatment approaches for optimizing patient outcomes.

Efficacy of Intravenous Ferric Carboxymaltose in Heart Failure Patients with Iron Deficiency Anemia: A Meta-analysis of 6271 Patients.

Iron deficiency is prevalent among heart failure patients and is associated with worse clinical outcomes, including decreased quality of life and functional capacity. This condition often results in a higher incidence of hospitalization and mortality. Iron supplementation, particularly with intravenous ferric carboxymaltose (FCM), has shown potential benefits as an adjunct therapy in heart failure management. This study aims to evaluate the efficacy of FCM in the treatment of patients with heart failure and iron deficiency anemia, with a focus on its impact on mortality and hospitalization rates. A comprehensive search was conducted in PubMed, Web of Science, and Scopus databases from their inception until 1st December 2023. Meta-analysis was performed using RevMan 5.4, employing a random-model effect. The results were reported as risk ratios (RRs), standard mean differences (SMDs), and 95 % confidence intervals (CIs). The meta-analysis included 13 studies with a total of 6271 patients. Ferric carboxymaltose administration resulted in a significant improvement in the 6-minute walk distance (SMD: 1.45; 95 % CI: 0.55, 2.36; p = 0.002), quality of life, as assessed by the Kansas City Cardiomyopathy Questionnaire (KCCQ) (SMD: 1.49; 95 % CI: 0.87, 2.11; p < 0.00001), the rate of first hospitalization for heart failure or cardiovascular death (RR: 0.91; 95 % CI: 0.84, 0.98; p = 0.02). However, FCM did not show a significant impact on the risk of cardiovascular death (RR: 0.90; 95 % CI: 0.77, 1.05; p = 0.17), the need for intervention due to worsening heart failure (RR: 0.41; 95 % CI: 0.04, 4.51; p = 0.47), or all-cause mortality rates (RR: 0.89; 95 % CI: 0.69, 1.16; p = 0.28). While FCM treatment in patients with heart failure and iron deficiency anemia significantly improves functional capacity and quality of life, it has no notable effect on mortality rates or the likelihood of hospitalization. These findings highlight the need for further research to explore comprehensive treatment strategies that address both the symptomatic and survival aspects of heart failure management in this patient population.

A Systematic Review and Meta-Analysis of Conditioned Pain Modulation in Children and Young People with Chronic Pain

Background/Objectives: Conditioned pain modulation (CPM) is a psychophysical experimental measure of the endogenous pain inhibitory pathway in humans, wherein one pain stimulus (the conditioning stimulus) is used to inhibit an individual’s perception of a second painful (test) stimulus. Research provides evidence of impaired endogenous inhibitory pain responses in adults with chronic pain. CPM is now increasingly applied in paediatric research and clinical practice. The primary aim of this systematic review was to examine the efficacy of CPM in paediatric chronic pain populations (6–24-year-olds) compared to pain-free children and young people (CYP). Methods: The protocol was registered on PROSPERO (CRD42020221927). A systematic search of seven databases was conducted from database inception to 20th June 2024. Study inclusion criteria were as follows: (i) recruited a sample of CYP aged 6 to 24 (inclusive) with chronic pain or who were pain-free; and (ii) applied a CPM paradigm comprising both a painful test and conditioning stimuli that were sufficiently detailed to allow for replication,(iii) adhered to a study design of randomised control trial, case control or cohort study, including cross-sectional or longitudinal; (iv) available in the English language. Study exclusion criteria were: (i) The CPM paradigm used a non-painful test or conditioning stimulus only; and (ii) was only available as an abstract, letter, poster, editorial, case report, or review with or without meta-analyses. Risk of bias was assessed using the Appraisal Tool for Cross Sectional Studies (AXIS). Meta-analyses were conducted in Comprehensive Meta Analysis 3.0 using random effects models to compare the overall CPM responses in CYP with chronic pain conditions to healthy control CYP. Results: Thirty-two studies were eligible for inclusion, six of which were included in one or more meta-analysis (n = 407 chronic pain, n = 205 control). Meta-analysis revealed significantly weaker CPM responses in CYP with a variety of chronic pain conditions compared to healthy controls (standardized mean difference (SMD) = 0.352), and significantly weaker CPM responses in CYP with abdominal pain conditions compared to healthy controls (SMD = 0.685). No significant difference in CPM response was found between CYP with migraine and healthy controls (SMD = −0.201). Conclusions: Variable results were found across individual studies, and the meta-analysis of the small number of eligible studies provides tentative evidence for impaired CPM in CYP with chronic pain compared to healthy controls. Further research is clearly needed. In particular, studies should present CPM results separately for different age groups, ethnic groups, and sexes, as these variables shape clinical pain responses.

Effect of Different Concentrations of Chlorhexidine on Anti-Plaque in Oral Care Practice: A Systematic Review and Network Meta-Analysis.

The aim of this network meta-analysis was to compare the anti-plaque effects and adverse effects of different concentrations of chlorhexidine (CHX). PubMed, OVID Embase and the Cochrane Library were searched from inception to October 2023 for randomised controlled trials (RCTs) of different concentrations of CHX in healthy populations. Random-effects network meta-analyses were performed to summarise the evidence, and the Grading of Recommendations Assessment, Development and Evaluation framework was used to rate the certainty of evidence. Cohen's d standardised mean differences were calculated as the measure of effect size. Thirty-eight RCTs involving 2011 participants and six concentrations of CHX (0.2%, 0.12%, 0.1%, 0.3%, 1% and 0.06%) were included. The anti-plaque effects of CHX at all concentrations were compared with placebo. Moderate to very low certainty evidence established 0.2% CHX as the most effective on anti-plaque. 0.12% and 0.1% CHX also showed significant anti-plaque effects. However, the ranking probabilities showed that the adverse effects of 0.12% and 0.1% CHX were < 0.2% CHX. Compared with placebo, 0.2%, 0.12% and 0.1% CHX had significant anti-plaque effects, with moderate to very low certainty evidence that 0.2% CHX was most effective on anti-plaque. However, 0.2% CHX had larger adverse effects than 0.12% and 0.1% CHX. PROSPERO: Number CRD: 42022327083.

Assessing the impact of telemedicine interventions on systolic and diastolic blood pressure reduction: A systematic review and meta-analysis.

Hypertension, characterized by high blood pressure, poses a significant risk for cardiovascular diseases, stroke, and heart attack. Managing it is particularly challenging in areas with limited healthcare access and for patients who cannot attend regular in-person visits. Telemedicine interventions offer a promising solution by improving patient adherence and facilitating timely treatment adjustments. This study aims to systematically evaluate the impact of these telemedicine interventions on reducing systolic and diastolic blood pressure. A comprehensive search of PubMed, Scopus, and Web of Science was conducted to identify relevant studies. Two independent reviewers screened and selected eligible articles, extracting key data using a standardized form. The quality of the included studies was assessed with the Mixed Methods Appraisal Tool (MMAT). A random effects model was used to combine the results, with treatment effects measured using standardized mean differences (Hedges's g). Consistency of findings was evaluated through statistical tests, including the Q test and I² statistic, to assess heterogeneity. Data analysis was conducted using Stata statistical software version 17.0. Of the 2700 articles retrieved, 35 studies were selected for inclusion in the analysis. Using a random-effects model, the overall effect size was Hedges's g = -0.22 (95% CI: -0.30 to -0.15; p-value < 0.001), indicating a small but meaningful reduction in blood pressure (systolic and diastolic). Telemedicine interventions had a greater impact on systolic blood pressure (Hedges's g = -0.27, 95% CI: -0.39 to -0.15; p-value < 0.001) compared to diastolic blood pressure (Hedges's g = -0.17, 95% CI: -0.26 to -0.07; p-value < 0.001), though both reductions were clinically relevant. This study demonstrates that telemedicine interventions significantly reduce both systolic and diastolic blood pressure, with a more pronounced effect on systolic pressure. The overall effect size indicates a small but meaningful improvement in hypertension management. These findings highlight the potential of telemedicine as an effective strategy for enhancing patient outcomes in hypertension care.
