RESUMO

Aim: Iron deficiency (ID) is associated with heart failure (HF) in a considerable proportion of patients. To improve the quality of life, lower the frequency of hospitalizations, and lower mortality rates of chronic HF patients (HF), this meta-analysis will look into the role of iron supplementation using ferric carboxymaltose (FCM). Methods & results: From inception until 1 October 2023, we conducted a thorough literature search of electronic databases for peer-reviewed publications. Around 5229 HF patients were included, of which 2691 received FCM while 2538 received placebo. Conclusion: FCM reduces HF-related hospitalizations but doesn't improve overall or cardiovascular mortality in those with HF and ID. The overall results support FCM's role in managing iron deficiency in heart failure.


Heart failure (HF) patients often suffer from iron deficiency (ID), worsening their symptoms and quality of life. Intravenous iron therapy, like ferric carboxymaltose (FCM), has been studied for its benefits in HF. This meta-analysis looked at existing research and found that FCM treatment reduced hospitalizations for HF but didn't significantly impact overall mortality. Although FCM improves patients' lives, more research is needed to understand its long-term effects fully. This study highlights the importance of addressing ID in HF management and supports FCM therapy as a beneficial option for HF patients.

RESUMO

Introduction: Various insulin therapies for Diabetes Mellitus offer different benefits while having potential risks. We aim to compare Insulin Icodec, a novel Insulin analogue with the ease of once-weekly administration, to the once-daily Insulin Glargine U100 regarding glycemic control and safety profile. Methods: We performed a systematic literature search of electronic databases for peer-reviewed articles from inception until September 1 2023. Results: A total of 2215 type 2 diabetic patients were included, of which 1209 received Insulin Icodec and1048 recieved Insulin Glargine U100. In terms of glycemic control, Insulin Icodec showed a significantly longer time in the target glucose range (MD: 0.304, CI: 0.069, P = 0.000) and a more significant reduction in HbA1c (MD: -0.154, CI: 0.003, P = 0.005) compared to Insulin Glargine U100. Fasting Plasma Glucose did not differ significantly. Insulin Icodec led to a more significant increase in body weight (MD: 0.161 kg, P = 0.029), while Insulin Glargine required a higher insulin dose (MD: 1.920 IU, P = 0.000). Regarding safety, the two groups had no significant differences in hypoglycemic events or adverse outcomes. Conclusion: Once-weekly Insulin Icodec demonstrates superior glycemic control with a reduced HbA1c compared to Once-Daily Insulin Glargine U100 while maintaining similar safety profiles.

RESUMO

Purpose: Excess body fat, insulin resistance, and abnormal lipid levels signal type 2 diabetes mellitus (DM2). Globally, 536.6 million people suffer from DM2, projected to rise to 783.2 million by 2045. Obesity fuels insulin resistance and DM2 development, with weight loss significantly improving glycemic control. Titrzepatide (TZP), a dual GIP and GLP-1 receptor agonist, proves highly effective in controlling hyperglycemia, stimulating insulin secretion, and promoting weight loss. TZP, holds promise as a treatment for DM2, surpassing insulin and GLP-1. The study aimed to meticulously assess the safety and efficacy of various doses, offering insights into optimal therapeutic strategies for managing DM2. Methods: This study aimed to comprehensively evaluate the safety and efficacy of TZP in treating DM2. The primary focus of the inclusion criteria was on trials comparing TZP with a placebo until November 23, 2023, excluding patients with certain comorbidities. Data extraction included key parameters, and outcomes were assessed for HbA1c levels, weight changes, fasting serum glucose levels, and various adverse events. Quality assessment utilized the Cochrane Collaboration's risk-of-bias tool, and a network meta-analysis explored outcomes across different TZP dosages. Results: This meta-analysis systematically reviewed ten studies on TZP for DM2. Results revealed significant reductions in HbA1c with TZP 10 mg (19%) and TZP 15 mg (31%) compared to TZP 5 mg (MD: -0.19 and MD: -0.32, respectively). Additionally, weight reduction was notable for TZP 10 mg (MD: -1.96) and TZP 15 mg (MD: -3.31). Fasting serum glucose showed improvement with TZP 15 mg (MD:-6.71). Gastrointestinal events increased with higher doses, yet without statistical significance. Death, nausea, diarrhea, vomiting, dyspepsia, decreased appetite, injection site reaction, hypoglycemia, treatment discontinuation, and serious adverse events showed no significant differences across doses. Conclusion: TZP effectively lowers HbA1c and induces weight loss across its three doses for type 2 diabetes management. The higher dose (15 mg) significantly reduces fasting serum glucose, with increased adverse events observed at higher doses. Dose-specific patterns for adverse effects emphasize the need to balance therapeutic benefits and risks. Further research is crucial for refining clinical applications and understanding TZP's role in DM2 management across doses.

RESUMO

BACKGROUND: Cardiovascular disease remains a significant global health concern, with high low-density lipoprotein cholesterol (LDL-C) levels contributing to an increased risk. Familial hypercholesterolemia (FH) further complicates its management, necessitating additional lipid-lowering therapies. Evinacumab, an angiopoietin-like protein 3 monoclonal antibody, has emerged as a potential treatment, particularly for patients with FH, by effectively reducing LDL-C and triglyceride levels. This meta-analysis aimed to evaluate the efficacy and safety of evinacumab across diverse patient populations. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, relevant randomized controlled trials (RCTs) were systematically retrieved from multiple databases until November 24, 2023. The inclusion criteria were studies comparing evinacumab (at doses of 5 and 15 mg) to placebo, with outcomes focusing on lipid levels and adverse events. Standardized protocols were employed for data extraction and quality assessment, and statistical analysis was conducted using RevMan software. RESULTS: Four RCTs, involving 270 patients, were included in the analysis. The analysis revealed significant reductions in lipid markers, particularly with the 15-mg dose of evinacumab, including triacylglycerols (standard mean difference [SMD] = -6.09, 95% confidence interval [CI] - 14.53 to 2.36, P = 0.16), total cholesterol (SMD = - 6.20, 95% CI - 11.53 to - 0.88, P = 0.02), high-density lipoprotein cholesterol (SMD = - 0.79, 95% CI - 1.27 to - 0.31, P = 0.001), LDL-C (SMD = - 4.58, 95% CI - 9.13 to - 0.03, P = 0.05), apolipoprotein (Apo) B (SMD = - 4.01, 95% CI - 7.53 to - 0.46, P = 0.03), and Apo C3 (SMD = - 7.67, 95% CI - 12.94 to - 2.41, P = 0.004). Adverse event analysis revealed no significant association, indicating good tolerability. CONCLUSION: High-dose evinacumab (15 mg) consistently demonstrated efficacy in reducing cholesterol and other lipid markers, with favorable tolerability. Further research is warranted to comprehensively assess its safety and clinical effectiveness, emphasizing the need for additional data to support its use in managing cardiovascular disease.

RESUMO

BACKGROUND: Nivolumab (Nivo) and ipilimumab (Ipi) have revolutionized cancer treatment by targeting different pathways. Their combination shows promising results in various cancers, including melanoma, but not all studies have demonstrated significant benefits. A meta-analysis was performed to assess the effectiveness and safety of Nivo-Ipi compared to Nivo alone in advanced cancer types (excluding melanoma). METHODS: Following PRISMA guidelines, we conducted a meta-analysis up to September 30, 2023, searching databases for randomized controlled trials (RCTs). We focused on advanced solid malignancies (excluding melanoma) with specific Nivo and Ipi dosing. Primary outcomes were overall survival (OS), progression-free survival (PFS), grades 3-4 adverse events (AEs), and treatment-related discontinuations. Secondary outcomes included specific adverse events. Statistical analysis in Review Manager included hazard ratio (HR) and risk ratio (RR), assessing heterogeneity (Higgins I2). RESULTS: Nine RCTs, involving 2152 patients covering various malignancies, were analyzed. The Nivo plus Ipi group exhibited a median OS of 12.3 months and a median PFS of 3.73 months, compared to monotherapy with 11.67 months and 3.98 months, respectively. OS showed no significant difference between Nivo and Ipi combination and Nivo alone (HR = 0.97, 95% CI: 0.88 to 1.08, p = 0.61). PFS had a slight improvement with combination therapy (HR = 0.91, 95% CI: 0.82 to 1.00, p = 0.04). Treatment-related cumulative grades 3-4 adverse events were higher with Nivo and Ipi (RR = 1.52, 95% CI: 1.30 to 1.78, p < 0.00001), as were treatment-related discontinuations (RR = 1.99, 95% CI: 1.46 to 2.70, p < 0.0001). Hepatotoxicity (RR = 2.42, 95% CI: 1.39 to 4.24, p = 0.002), GI toxicity (RR = 2.84, 95% CI: 1.44 to 5.59, p = 0.002), pneumonitis (RR = 2.29, 95% CI: 1.24 to 2.23, p = 0.008), dermatitis (RR = 2.96, 95% CI: 1.08 to 8.14, p = 0.04), and endocrine dysfunction (RR = 6.22, 95% CI: 2.31 to 16.71, p = 0.0003) were more frequent with Nivo and Ipi. CONCLUSIONS: Combining nivolumab and ipilimumab did not significantly improve overall survival compared to nivolumab alone in advanced cancers (except melanoma). However, it did show slightly better PFS at the cost of increased toxicity, particularly grades 3-4 adverse events. Specific AEs occurred more frequently in the combination group. Further trials are needed to fully assess this combination in treating advanced cancers.

RESUMO

Introduction: Stroke is a significant global health concern, and numerous studies have established a link between depression and an increased risk of stroke. While many investigations explore this link, some overlook its long-term effects. Depression may elevate stroke risk through physiological pathways involving nervous system changes and inflammation. This systematic review and meta-analysis aimed to assess the association between depression and stroke. Methodology: We conducted a comprehensive search of electronic databases (PubMed, Embase, Scopus, and PsycINFO) from inception to 9 April 2023, following the Preferred Reporting Items for Systemic Review and Meta-analysis (PRISMA) and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. We included all articles assessing the association between different stroke types and depression, excluding post-stroke depression. Two investigators independently extracted data and assessed quality using the Newcastle-Ottawa Scale and Cochrane Risk of Bias tool, utilizing a random-effects model for data synthesis. The primary outcome was the association of depression with stroke, with a secondary focus on the association of antidepressants with stroke. Results: The initial search yielded 10,091 articles, and 44 studies were included in the meta-analysis. The pooled analysis revealed a significant association between depression and stroke risk, with an overall hazard ratio of 1.41 (95% CI 1.32, 1.50; p < 0.00001), indicating a moderately positive effect size. Subgroup analyses showed consistent associations with ischemic stroke (HR = 1.30, 95% CI 1.13, 1.50; p = 0.007), fatal stroke (HR = 1.39, 95% CI 1.24, 1.55; p < 0.000001), and hemorrhagic stroke (HR = 1.33, 95% CI 1.01, 1.76; p = 0.04). The use of antidepressants was associated with an elevated risk of stroke (HR = 1.28, 95% CI 1.05, 1.55; p = 0.01). Conclusion and relevance: This meta-analysis indicates that depression moderately raises the risk of stroke. Given the severe consequences of stroke in individuals with depression, early detection and intervention should be prioritized to prevent it. Systematic review registration: Prospero (CRD42023472136).

RESUMO

Background: This study strives to provide a current and thorough assessment of the comparative efficacy and safety between equiosmolar quantities of hypertonic saline (HS) and mannitol in facilitating brain relaxation for patients undergoing elective craniotomies. Methods: This systematic review and meta-analysis, following preferred reporting items for systematic reviews and meta-analyses guidelines, compared the efficacy and safety of equiosmolar concentrations of mannitol and HS in elective craniotomies. PubMed, Scopus, Cochrane Library, ScienceDirect, and Proquest databases were searched using keywords related to mannitol, HS, and craniotomy. Results were analyzed through a random-effects model using Mantel-Haenszel risk ratio and standard mean difference. P < 0.05 was considered significant. Results: Thirteen randomized controlled trials encompassing 965 patients (516 in the HS group and 448 in the mannitol group) were analyzed. The quality of studies was moderate-to-high, and no significant publication bias was observed. The primary outcome, brain relaxation, favored HS over mannitol without significant heterogeneity. Mannitol was associated with increased urine output compared to HS, irrespective of dose, with high heterogeneity. HS was linked to significantly reduced fluid input, confirmed by subgroup analysis with lower heterogeneity. No significant difference was found in serum osmolality between the two agents. Serum sodium (Na+) levels favored HS, whereas arterial blood Na+ levels also favored HS despite considerable heterogeneity. Maximum mean arterial pressure was higher with HS, but it displayed significant heterogeneity. Maximum central venous pressure showed no significant difference between the two agents, with moderate heterogeneity. Conclusion: HS appears more effective than mannitol in achieving brain relaxation, and it may offer advantages in fluid management and Na+ balance. Clinicians should consider these findings when selecting hyperosmotic agents for neurosurgical procedures. Further research is needed to address heterogeneity in certain outcomes and guide clinical practice.

RESUMO

This comprehensive review delves into the current updates and challenges associated with the management of low-grade gliomas (LGG), the predominant primary tumors in the central nervous system. With a general incidence rate of 5.81 per 100000, gliomas pose a significant global concern, necessitating advancements in treatment techniques to reduce mortality and morbidity. This review places a particular focus on immunotherapies, discussing promising agents such as Zotiraciclib and Lerapolturev. Zotiraciclib, a CDK9 inhibitor, has demonstrated efficacy in glioblastoma treatment in preclinical and clinical studies, showing its potential as a therapeutic breakthrough. Lerapolturev, a viral immunotherapy, induces inflammation in glioblastoma and displays positive outcomes in both adult and pediatric patients. Exploration of immunotherapy extends to Pembrolizumab, Nivolumab, and Entrectinib, revealing the challenges and variabilities in patient responses. Despite promising preclinical data, the monoclonal antibody Depatuxizumab has proven ineffective in glioblastoma treatment, emphasizing the critical need to understand resistance mechanisms. The review also covers the success of radiation therapy in pediatric LGG, with evolving techniques, such as proton therapy, showing potential improvements in patient quality of life. Surgical treatment is discussed in the context of achieving a balance between preserving the patient's quality of life and attaining gross total resection, with the extent of surgical resection significantly influencing the survival outcomes. In addition to advancements in cancer vaccine development, this review highlights the evolving landscape of LGG treatment, emphasizing a shift toward personalized and targeted therapies. Ongoing research is essential for refining strategies and enhancing outcomes in the management of LGG.

RESUMO

Background: Alzheimer's disease (AD) is a widespread neurodegenerative disorder with a significant global impact, affecting approximately 50 million individuals, and projections estimate that up to 152 million people will be affected by 2050. AD is characterized by beta-amyloid plaques and tau tangles in the brain, leading to cognitive decline. Summary: Recent research on AD has made significant strides, including the development of an "amyloid clock" biomarker that tracks AD progression through positron emission tomography (PET) scans. Surf4 and other genes have been discovered to play a role in regulating beta-amyloid toxicity, while inhibiting the enzyme hexokinase-2 has shown positive results in preclinical studies. New brain mapping techniques have identified early brain-based causes of cognitive changes in AD, and biomarkers such as neuronal pentraxin protein Nptx2 and astrocytic 7-subunit of the nicotinic acetylcholine receptors (7nAChRs) show potential for early detection. Other approaches, such as replenishing the enzyme Tip60, selectively degrading the modified protein p-p38 with PRZ-18002, and targeting the protein voltage-dependent anion channel-1 (VDAC1), have shown promise in enhancing cognitive function and preventing pathophysiological alterations linked to AD. Baseline blood samples and other biomarkers such as urine formic acid, p-tau 198, microRNAs, and glial fibrillary acidic protein (GFAP) have also been discovered for early detection and intervention of AD. Additionally, recent FDA approvals for medications such as aducanumab and lecanemab provide options for reducing AD symptoms and improving function, while clinical trials for dementia vaccines show promise for the nasal and beta-amyloid 40 vaccines as well as vaccinations targeting tau. Key Messages: These advancements in AD research, including biomarker discovery and the development of disease-modifying treatments, are crucial steps towards improving the lives of those affected by AD and finding a cure for this debilitating disease.

RESUMO

BACKGROUND: Neurosurgery has 1 of the highest risks for medical malpractice claims. We reviewed the factors associated with neurosurgical malpractice claims and litigation in the United States and reported the outcomes through a systematic review of the literature. METHODS: We conducted a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines using the Medline, Embase, Cochrane, PubMed, and Google Scholar databases. We sought to identify pertinent studies containing information about medical malpractice claims and outcomes involving neurosurgeons in the United States. RESULTS: We identified 15 retrospective studies spanning from 2002 to 2023 that reviewed over 7890 malpractice claims involving practicing neurosurgeons in the United States. Disparities were evident in neurosurgical litigation, with 474 cases linked to brain-related surgeries and a larger proportion, 1926 cases, tied to spine surgeries. The most commonly filed claims were intraprocedural errors (37.4%), delayed diagnoses (32.1%), and failure to treat (28.8%). Less frequently filed claims included misdiagnosis or choice of incorrect procedure (18.4%), occurrence of death (17.3%), test misinterpretation (14.4%), failure to appropriately refer patients for evaluation/treatment (14.3%), unnecessary surgical procedures (13.3%), and lack of informed consent (8.3%). The defendant was favored in 44.3% of claims, while in 31.3% of lawsuits were dropped, 17.7% of verdicts favored the plaintiff, and 16.6% reached an out of court settlement. Only 3.5% of lawsuits found both parties liable. CONCLUSION: Neurosurgery is a high-risk specialty with 1 of the highest rates of malpractice claims. Spine claims had a significantly higher rate of filed malpractice claims, while cranial malpractice claims were associated with higher litigation compensation. Predictably, spinal cord injuries play a crucial role in predicting litigation. Importantly, nonsurgical treatments are also a common source of liability in neurosurgical practice.
