Magnetic Resonance-guided Laser Interstitial Thermal Therapy in the Management of Hypothalamic Hamartomas: A Systematic Review and Meta-analysis.

INTRODUCTION: Magnetic resonance-guided laser interstitial thermal therapy (MRg-LITT) is a promising new technique to ablate epileptic foci in patients with hypothalamic hamartoma (HH). We aim to systematically synthesize all available evidence and determine the effectiveness of MRg-LITT in reducing seizures in patients with HH. METHODS: We systematically searched MEDLINE (PubMed), Embase (Ovid), Scopus, and Google Scholar for all relevant articles. We used Open[Meta]Analyst to pool the number of seizure free patients after MRg-LITT treatment in a Random Effects model. Risk ratios (RRs) were calculated, and subgroups were analyzed. Comprehensive Meta Analysis was used to assess publication bias via funnel plots, Egger's regression test and Begg's correlation test. This review complies with the PRISMA guidelines. RESULTS: After screening the titles, abstracts, and full texts, we included seventeen articles in our meta-analysis, which revealed a 77.1% rate of seizure freedom (95% CI 0.696 to 0.837, p < 0.001), with moderate heterogeneity (I2 = 49.46%). Subgroup analysis by study design and sensitivity analyses excluding one study at a time did not impact the results substantially, and we found no evidence of publication bias. Adverse effects included electrolyte imbalances, weight gain, and transient neurologic disturbances. CONCLUSION: Magnetic resonance-guided laser interstitial thermal therapy might be a feasible and effective technique for ablation of epileptic foci, leading to seizure freedom in a large proportion of patients with hypothalamic hamartoma. However, there is a paucity of literature on the topic, and prospective clinical trials with larger number of participants, comparing MRg-LITT to open surgery, are needed.

Intraventricular Glioblastomas: A Systematic Review of Multimodal Treatment Strategies.

AIM: Intraventricular glioblastomas (IVGBMs) are rare tumors within the central nervous system characterized by unique challenges in diagnosis and management due to their location within the ventricular system. Despite their rarity, these tumors necessitate comprehensive study to refine diagnostic approaches and optimize therapeutic strategies. METHODS: A systematic review was conducted using PubMed, Scopus, Web of Science, and Google Scholar databases to identify relevant literature published up to January 2024. Inclusion criteria encompassed studies in English focusing on clinical characteristics, radiological features, pathology, and treatment of IVGBM. Data synthesis and analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Twenty-four articles met the inclusion criteria, comprising 47 patients with IVGBM. The median age was 47 years, with a male predominance (32 males, 15 females). Common symptoms included increased intracranial pressure and seizures. Tumors predominantly affected the lateral ventricles (body and trigone). Surgical resection (subtotal or gross total) was the primary treatment approach, with adjuvant therapies (radiotherapy, chemotherapy) administered postoperatively. CONCLUSIONS: IVGBM present distinct diagnostic and therapeutic challenges due to their ventricular location. Current treatments primarily involve surgical resection followed by adjuvant therapies, though outcomes remain guarded. Further research is needed to enhance understanding and management of this rare glioblastoma subset.

The use of modafinil for the treatment of fatigue in multiple sclerosis: A systematic review and meta-analysis of controlled clinical trials.

INTRODUCTION: Multiple sclerosis (MS) is a debilitating neurological condition affecting nearly one million people across the United States. Among the most prominent symptoms of the condition are excessive fatigue and daytime sleepiness. Numerous clinical trials have investigated the efficacy of modafinil in addressing fatigue among these patients. OBJECTIVE: The objective of the present study is to assess the safety and efficacy of modafinil for the treatment of fatigue in MS. METHODOLOGY: An electronic search of PUBMED, ScienceDirect, and Cochrane Central was conducted for articles published from inception to December 2023 using search terms such as "modafinil," "fatigue," and "MS." RESULTS: Seven studies were included in our analysis. Modafinil leads to a meaningful reduction in fatigue when compared with placebo, as measured by Modified Fatigue Impact Scale [mean difference (MD) = -4.42 [-8.01, -.84]; I2 = 45%; p = .02] and Epworth Sleepiness Scale [MD = -.87 [-1.64, -.10]; I2 = 0%; p = .03]. Modafinil also demonstrated a greater risk of precipitating adverse events (e.g., insomnia, gastrointestinal symptoms) when compared with placebo [RR = 1.30 [1.03, 1.66]; I2 = 0%; p = .03]. In quality-of-life assessments, modafinil was associated with overall improvement in well-being [standardized mean difference = .18 [.01, .35]; I2 = 56%; p = .04]. CONCLUSION: The data indicates that modafinil confers a therapeutic benefit when treating fatigue in patients with MS and improves overall quality of life; however, there is a risk of precipitating adverse events. Ultimately, higher quality of evidence may be required to better inform clinical management.

Comparison of Acute Effects of E-cigarettes With and Without Nicotine and Tobacco Cigarettes on Hemodynamic and Endothelial Parameters: A Systematic Review and Meta-analysis.

INTRODUCTION: Smoke from traditional cigarettes and e-cigarette aerosols have distinct chemical compositions that may impact blood pressure (BP) and heart rate (HR) differently. AIMS: This study compared the impact of nicotine-containing e-cigarettes (EC+) versus nicotine-free (EC-) on BP, HR and endothelial markers, and assessed if EC+ posed fewer risks than tobacco cigarettes (TC). METHODS: Electronic databases were searched from inception until November 2023 for studies reporting changes in systolic and diastolic BP (SBP, DBP) and HR and endothelial parameters before and after the use of EC+, EC- and TC. Data were analyzed using weighted mean differences (WMDs) and 95% confidence intervals (CIs). RESULTS: Fifteen studies (n = 752) were included in our meta-analysis. We demonstrate that EC+ significantly increased systolic BP (WMD = 3.41, 95% CI [0.1,6.73], p = 0.04], diastolic BP (WMD = 3.42, 95% CI [1.75, 5.09]; p < 0.01], and HR (WMD = 5.36 BPM, 95% CI [1.87, 8.85]; p < 0.01) compared to EC-. However, EC+ was observed to cause less detrimental effect on SBP (WMD = - 4.72 mmHg, 95% CI [- 6.58, - 2.86], p < 0.01), and HR (WMD = - 3.11 BPM, 95% CI [- 4.54, - 1.68]; p < 0.01) as compared to TC with no difference on DBP (WMD = - 1.14 mmHg, 95% CI [- 2.38, 0.1]; p = 0.07). EC+ also led to greater deterioration of endothelial parameters as compared to EC- but to a lesser degree as compared to TC. CONCLUSION: EC+ shows greater impairment in hemodynamic and endothelial parameters than EC- but less than TC. Additional studies are needed to evaluate prolonged effects of EC use.

Insights into Anton Syndrome: When the brain denies blindness.

INTRODUCTION: Anosognosia, a neurological condition, involves a lack of awareness of one's neurological or psychiatric deficits. Anton Syndrome (AS), an unusual form of anosognosia, manifests as bilateral vision loss coupled with denial of blindness. This systematic review delves into 64 studies encompassing 72 AS cases to explore demographics, clinical presentations, treatments, and outcomes. MATERIALS AND METHODS: The study rigorously followed PRISMA guidelines, screening PubMed, Google Scholar, and Scopus databases without timeframe limitations. Only English human studies providing full text were included. Data underwent thorough assessment, examining patient demographics, etiological variables, and treatment modalities. RESULTS: Sixty-four studies met the stringent inclusion criteria. Examining 72 AS cases showed a median age of 55 (6 to 96 years) with no gender preference. Hypertension (34.7 %) and visual anosognosia (90.3 %) were prevalent. Stroke (40.3 %) topped causes. Management included supportive (30.6 %) and causal approaches (30.6 %). Improvement was seen in 45.8 %, unchanged in 22.2 %, and deterioration in 11.1 %. Anticoagulation correlated with higher mortality (p < 0.05). DISCUSSION: AS, an unusual manifestation of blindness, stems mainly from occipital lobe damage, often due to cerebrovascular incidents. The syndrome shares features with Dide-Botcazo syndrome and dates back to Roman times. Its causes range from strokes to rare conditions like multiple sclerosis exacerbation. Accurate diagnosis involves considering clinical presentations and imaging studies, distinguishing AS from similar conditions. CONCLUSION: This comprehensive review sheds light on AS's complex landscape, emphasizing diverse etiologies, clinical features, and treatment options. Tailored treatments aligned with individual causes are crucial. The study's findings caution against blanket anticoagulation therapy, suggesting a nuanced approach. Further research is pivotal to refine diagnostics and optimize care for AS individuals.

A Systematic Review of Nanomedicine in Glioblastoma Treatment: Clinical Efficacy, Safety, and Future Directions.

(1) Background: Glioblastoma (GBM) is categorized as a grade IV astrocytoma by the World Health Organization (WHO), representing the most aggressive and prevalent form of glioma. It presents a significant clinical challenge, with limited treatment options and poor prognosis. This systematic review evaluates the efficacy and safety of various nanotherapy approaches for GBM and explores future directions in tumor management. Nanomedicine, which involves nanoparticles in the 1-100 nm range, shows promise in improving drug delivery and targeting tumor cells. (2) Methods: Following PRISMA guidelines, a systematic search of databases including Google Scholar, NCBI PubMed, Cochrane Library, and ClinicalTrials.gov was conducted to identify clinical trials on GBM and nanomedicine. The primary outcome measures were median overall survival, progression-free survival, and quality of life assessed through Karnofsky performance scores. The safety profile was assessed by adverse events. (3) Results: The analysis included 225 GBM patients, divided into primary and recurrent sub-populations. Primary GBM patients had a median overall survival of 6.75 months, while recurrent GBM patients had a median overall survival of 9.7 months. The mean PFS period was 2.3 months and 3.92 months in primary GBM and recurrent GBM patients, respectively. Nanotherapy showed an improvement in quality of life, with KPS scores increasing after treatment in recurrent GBM patients. Adverse events were observed in 14.2% of patients. Notably, Bevacizumab therapy exhibited better survival outcomes but with a higher incidence of adverse events. (4) Conclusions: Nanotherapy offers a modest increase in survival with fewer severe side effects. It shows promise in improving the quality of life, especially in recurrent GBM patients. However, it falls short in terms of overall survival compared to Bevacizumab. The heterogeneous nature of treatment protocols and reporting methods highlights the need for standardized multicenter trials to further evaluate the potential of nanomedicine in GBM management.
