Factors associated with development of depression in adult patients with brain arteriovenous malformations.

Objective: Cerebrovascular diseases are often associated with the development of depression, but few studies have assessed this association with brain arteriovenous malformations (bAVMs). We aim to explore the association of brain arteriovenous malformation(bAVM) with new onset depression at follow-up.

Methods: We performed a retrospective cohort study on adult bAVMs patients using an institutional bAVM database.

Optimizing surgical strategies: a systematic review of the effectiveness of preoperative arterial embolization for hyper vascular metastatic spinal tumors.

Background: The vertebral column is the most common site of bony metastasis. When indicated, surgical resection of hypervascular metastatic lesions may be complicated by significant blood loss, the need for blood transfusion, and incomplete tumor resection due to poor visualization and premature abortion of the operation. In select cases, preoperative arterial embolization of hypervascular metastatic tumors may help minimize intraoperative bleeding and reduce operative times.

The role of combination surgery and radiotherapy in patients with metastatic spinal cord compression: What are the remaining grey areas? A systematic review.

Objective: Traditional management of patients with metastatic epidural spinal cord compression (MESCC) consists of radiotherapy (RT) with or without surgical decompression. With extensive literature and the introduction of clinical frameworks, such as the neurologic, oncologic, mechanical, and systemic criteria and the epidural spinal cord compression scale, progress has been made in refining the appropriate treatment regimen. In this review, we analyze the existing literature to identify the consensus frameworks and the remaining gaps in clinical knowledge.

Methods: MEDLINE and PubMed were searched from inception to March 17, 2024.

Inferring the roles of individuals in collective systems using information-theoretic measures of influence.

In collective systems, influence of individuals can permeate an entire group through indirect interactionscom-plicating any scheme to understand individual roles from observations. A typical approach to understand an individuals influence on another involves consideration of confounding factors, for example, by conditioning on other individuals outside of the pair. This becomes unfeasible in many cases as the number of individuals increases.

Utilizing Data and Alarm Champions to Enhance Alarm Management: A Pediatric Quality Improvement Initiative.

Background: Nuisance and false alarms distract clinicians from urgent alerts, raising patient safety risks.

Local Problem: High alarm rates in a pediatric progressive care unit resulted in experiencing 180-250 alarms per day or 1 alarm every 3 to 4 minutes per clinician.

Methods: Through Plan-Do-Study-Act cycles, environmental, policy, and technology changes were implemented to decrease the average alarms/day/bed and percentage of time in alarm.

Development of a novel Z-scheme CoNiTiO/CdS (x = 0.5) photocatalyst for the efficient degradation of organic pollutants via a visible-light-driven photocatalytic process.

Herein, for the first time, we reported the synthesis of a novel Z-scheme CoNiTiO/CdS (x = 0.5) heterojunction photocatalyst and the investigation of its visible-light-driven photocatalytic performance toward degradation of methylene blue (MB). The developed photocatalyst was structurally characterized by applying X-Ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET), differential reflectance spectroscopy (DRS), and photoluminescence (PL) techniques.

Advances in Implant Technologies for Spine Surgery.

Spine implants are becoming increasingly diversified. Taking inspiration from other industries, three-dimensional modeling of the spinal column has helped meet the custom needs of individual patients as both en bloc replacements and pedicle screw designs. Intraoperative tailoring of devices, a common need in the operating room, has led to expandable versions of cages and interbody spacers.

Distinct Effects of Brain Activation Using tDCS and Observational Practice: Implications for Motor Rehabilitation.

Complex motor skills can be acquired while observing a model without physical practice. Transcranial direct-current stimulation (tDCS) applied to the primary motor cortex (M1) also facilitates motor learning. However, the effectiveness of observational practice for bimanual coordination skills is debated.

Association of socioeconomic status with the management outcome of unruptured intracranial arteriovenous malformation.

Objective: The longitudinal management of unruptured brain arteriovenous malformation (bAVM) is crucial. To date, no study in the United States has evaluated the impact of socioeconomic status (SES) on bAVM outcome. Herein, the authors aimed to clarify the impact of SES, as indicated by the area deprivation index (ADI), on bAVM outcome.

Cost-Effectiveness of a Direct-Aspiration First-Pass Technique versus Stent Retriever in Mechanical Thrombectomy.

Objective: A direct-aspiration first-pass technique (ADAPT) in mechanical thrombectomy has been described in recent studies as an efficacious strategy compared with using a stent retriever (SR). We sought to evaluate for cost differences of ADAPT technique versus SR as an initial approach.

Methods: We conducted a retrospective analysis of consecutive patients with mechanical thrombectomy at our institution between 2022 and 2023.

Diagnostic test accuracy of machine learning algorithms for the detection intracranial hemorrhage: a systematic review and meta-analysis study.

Background: This systematic review and meta-analysis were conducted to objectively evaluate the evidence of machine learning (ML) in the patient diagnosis of Intracranial Hemorrhage (ICH) on computed tomography (CT) scans.

Methods: Until May 2023, systematic searches were conducted in ISI Web of Science, PubMed, Scopus, Cochrane Library, IEEE Xplore Digital Library, CINAHL, Science Direct, PROSPERO, and EMBASE for studies that evaluated the diagnostic precision of ML model-assisted ICH detection. Patients with and without ICH as the target condition who were receiving CT-Scan were eligible for the research, which used ML algorithms based on radiologists' reports as the gold reference standard.

Pressure-volume mechanics of inflating and deflating intact whole organ porcine lungs.

Pressure-volume curves of the lung are classical measurements of lung function and are impacted by changes in lung structure due to disease or shifts in air-delivery volume or cycling rate. Diseased and preterm infant lungs have been found to show heterogeneous behavior which is highly frequency dependent. This breathing rate dependency has motivated the exploration of multi-frequency oscillatory ventilators to deliver volume oscillation with optimal frequencies for various portions of the lung to provide more uniform air distribution.
