RESUMEN

Cerebral aneurysms, affecting 2-5% of the global population, are often asymptomatic and commonly located within the Circle of Willis. A recent study in Neurosurgical Review highlights a significant reduction in the annual rupture rates of unruptured cerebral aneurysms (UCAs) in Japan from 2003 to 2018. By analyzing age-adjusted mortality rates of subarachnoid hemorrhage (SAH) and the number of treated ruptured cerebral aneurysms (RCAs), researchers found a substantial decrease in rupture rates-from 1.44 to 0.87% and from 0.92 to 0.76%, respectively (p < 0.001). This 88% reduction was largely attributed to improved hypertension management. Recent advancements in artificial intelligence (AI) and machine learning (ML) further support these findings. The RAPID Aneurysm software demonstrated high accuracy in detecting cerebral aneurysms on CT Angiography (CTA), while ML algorithms showed promise in predicting aneurysm rupture risk. A meta-analysis indicated that ML models could achieve 83% sensitivity and specificity in rupture prediction. Additionally, deep learning techniques, such as the PointNet + + architecture, achieved an AUC of 0.85 in rupture risk prediction. These technological advancements in AI and ML are poised to enhance early detection and risk management, potentially contributing to the observed reduction in UCA rupture rates and improving patient outcomes.

RESUMEN

Deep Brain Stimulation (DBS), an FDA-approved treatment for movement disorders such as Parkinson's Disease (PD), is increasingly used for various neurological and neuropsychiatric conditions. A recent systematic review and meta-analysis by Bahadori et al. highlighted a significant increase in Body Mass Index (BMI) among patients post-DBS, with most participants having PD. The study, however, noted moderate heterogeneity (I² = 67.566%) without thoroughly addressing its potential causes or proposing strategies to mitigate it. The review's limited patient diversity and short follow-up period also challenge its generalizability and long-term implications. In addition to BMI changes, DBS has been linked to motor, cognitive, and psychiatric side effects. Patients undergoing subthalamic nucleus (STN) stimulation, for example, face risks of motor complications, including speech and gait issues, while cognitive declines, particularly in verbal fluency and executive function, are also concerning. Psychiatric side effects such as depression, anxiety, and psychosis further complicate treatment outcomes. These findings underscore the importance of personalized treatment strategies, preoperative assessments, and ongoing patient education to minimize adverse effects and optimize the therapeutic potential of DBS.

RESUMEN

Cerebral aneurysm rupture, the predominant cause of non-traumatic subarachnoid hemorrhage, underscores the need for effective treatment and early detection methods. A study in Neurosurgical Review compared microsurgical clipping to endovascular therapy in 130 patients with middle cerebral artery (MCA) aneurysms, finding significantly fewer serious adverse events (SAEs) and neurological complications in the endovascular group. This suggests endovascular therapy's superiority in safety and reducing complications for MCA aneurysm patients. Furthermore, a systematic review and meta-analysis assessed the diagnostic accuracy of AI algorithms in detecting cerebral aneurysms, revealing a high sensitivity but notable false-positive rates, indicating AI's potential while highlighting the need for further validation. Machine learning algorithms also showed promise in predicting cerebral aneurysm rupture risk, demonstrating reasonable sensitivity and specificity. Additionally, AI-based radiomics models are advancing rapidly, offering enhanced predictive accuracy and personalized treatment planning by analyzing imaging data to identify features indicative of aneurysm conditions. Collectively, these findings emphasize the advantages of endovascular therapy for MCA aneurysms and the emerging role of AI and machine learning in improving early detection and personalized management of cerebral aneurysms.

RESUMEN

Papillary glioneuronal tumors (PGNTs), classified as Grade I by the WHO in 2016, present diagnostic challenges due to their rarity and potential for malignancy. Xiaodan Du et al.'s recent study of 36 confirmed PGNT cases provides critical insights into their imaging characteristics, revealing frequent presentation with headaches, seizures, and mass effect symptoms, predominantly located in the supratentorial region near the lateral ventricles. Lesions often appeared as mixed cystic and solid masses with septations or as cystic masses with mural nodules. Given these complexities, artificial intelligence (AI) and machine learning (ML) offer promising advancements for PGNT diagnosis. Previous studies have demonstrated AI's efficacy in diagnosing various brain tumors, utilizing deep learning and advanced imaging techniques for rapid and accurate identification. Implementing AI in PGNT diagnosis involves assembling comprehensive datasets, preprocessing data, extracting relevant features, and iteratively training models for optimal performance. Despite AI's potential, medical professionals must validate AI predictions, ensuring they complement rather than replace clinical expertise. This integration of AI and ML into PGNT diagnostics could significantly enhance preoperative accuracy, ultimately improving patient outcomes through more precise and timely interventions.

RESUMEN

Intracerebral hemorrhage (ICH) is a severe form of stroke with high morbidity and mortality, accounting for 10-15% of all strokes globally. Recent advancements in prognostic biomarkers and predictive models have shown promise in enhancing the prediction and management of ICH outcomes. Serum sestrin2, a stress-responsive protein, has been identified as a significant prognostic marker, correlating with severity indicators such as NIHSS scores and hematoma volume. Its levels predict early neurological deterioration and poor prognosis, offering predictive capabilities comparable to traditional measures. Furthermore, a deep learning-based AI model demonstrated superior performance in predicting early hematoma enlargement, with higher sensitivity and specificity than conventional methods. Additionally, long-term outcome prediction models using CT radiomics and machine learning have achieved high accuracy, particularly with the Random Forest algorithm. These advancements underscore the potential of integrating novel biomarkers and advanced computational techniques to improve prognostication and management of ICH, aiming to enhance patient care and survival rates. The incorporation of serum sestrin2, AI, and machine learning in predictive models represents a significant step forward in the clinical management of ICH, offering new avenues for research and clinical application.

RESUMEN

BACKGROUND: Stroke remains the second leading cause of death worldwide, with a 20% risk of recurrence within 5 years. Preventing secondary stroke events is crucial for patient management. Kraft et al. highlighted the potential of telemedicine in secondary prevention, but noted the need for further research. Our study incorporates recent trials to provide an updated analysis of telemedical strategies in stroke prevention. METHODS: We reviewed and analyzed RCTs and observational studies from PubMed, Cochrane, Google Scholar, and Clinicaltrials.gov (May 19, 2016 - March 20, 2024) comparing telephone-based follow-up to standard care in stroke patients. The meta-analysis focused on SBP changes within 12 months. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies, sourced from PubMed, Cochrane, Google Scholar, and ClinicalTrials.gov (May 19, 2016 - March 20, 2024). We compared telephone-based follow-up to standard care in stroke patients, and the primary outcome was systolic blood pressure (SBP) changes within 12 months. RESULTS: Our systematic review included data from 21,904 patients. The meta-analysis focused on studies with comparable systolic blood pressure (SBP) data. It involved 3,501 individuals in the control group and 3,485 in the experimental group. The analysis revealed a significant reduction in SBP with telemedicine strategies for secondary stroke prevention, with a p-value of 0.003. Additionally, a systemic review of the included studies demonstrated that these strategies improved medication adherence, lifestyle habits, and physical performance, positively correlating with better health outcomes and reduced mortality risk. CONCLUSION: With the inclusion of recent clinical trials, our updated systematic review and meta-analysis concludes that telemedicine supports secondary prevention in cerebrovascular diseases, particularly blood pressure control. While telemedicine may have a role in reducing recurrent stroke risk, we believe further studies with longer follow-up periods are needed to validate the role of telemedical strategies in reducing recurrence rates.

RESUMEN

BACKGROUND: Kidney transplantation remains the best possible solution for patients with chronic kidney disease, providing better long-term outcomes and drastically improving quality of life. However, it comes with its own set of risks. The use of immunosuppressives following renal transplants has been shown to increase the development of malignancies and infections, and the occurrence of post-transplant malignancies is now the third most common cause of death in transplant patients. This involves multiple mechanisms, including the carcinogenic tendency of some immunosuppressive drugs, along with the induction and promotion of post-transplant malignancies by certain viruses. The quantification of Cancer risk must be made an integral part of the overall management of transplant patients, and appropriate follow-up screening needs to be adopted. Kaposi's sarcoma, lymphoma, and non-melanoma skin cancers have a greater incidence. If a malignancy develops immediately after transplantation, it may have been transmitted from the donor; donor-transmitted and donor-derived tumours may be differentiated based on a two-year time limit. Immunosuppressive medications with carcinogenic tendencies, reduced immunological control of oncogenic viruses, and poor immunosurveillance remain the most important risk factors. The gravity of this situation is further exacerbated by the fact that not only is there an increased risk of developing these malignancies in the post-transplant period, but the prognosis is also worsened when compared to non-transplant patients. All transplant centers should therefore adopt a multidisciplinary approach including early detection and prompt treatment, to improve outcomes in transplanted patients.
