Intraoperative angiography via popliteal artery access for spinal neurovascular lesions: an institutional experience and systematic review.

Background: Intraoperative DSA is used to confirm complete obliteration of neurovascular pathologies. For spinal neurovascular lesions, femoral access can be challenging given the need to flip the patient after sheath placement. Similarly, radial access can be complicated by arch navigation difficulties.

Comaneci-assisted coiling of a right posterior communicating artery aneurysm: an unusual case of coil retention.

Although endovascular embolization has become the main treatment option for intracranial aneurysms,1 2 wide-necked intracranial aneurysms remain difficult to coil.3 Both stent- and balloon-assisted coiling are used for wide-necked aneurysms because they provide a scaffold that protects the parent vessel during coiling.4 5 However, stent-assisted coiling requires dual antiplatelet therapy, which increases the risk of bleeding, whereas balloon-assisted coiling temporarily obstructs blood flow.

Measuring the Burden of Infodemics: Summary of the Methods and Results of the Fifth WHO Infodemic Management Conference.

Background: An infodemic is excess information, including false or misleading information, that spreads in digital and physical environments during a public health emergency. The COVID-19 pandemic has been accompanied by an unprecedented global infodemic that has led to confusion about the benefits of medical and public health interventions, with substantial impact on risk-taking and health-seeking behaviors, eroding trust in health authorities and compromising the effectiveness of public health responses and policies. Standardized measures are needed to quantify the harmful impacts of the infodemic in a systematic and methodologically robust manner, as well as harmonizing highly divergent approaches currently explored for this purpose.

Toward a New Mathematical Definition of Datums in Standards to Support Advanced Manufacturing.

Recent advances in the digitization of manufacturing have prompted ASME and International Organization for Standardization (ISO) standards committees to reexamine the definition of datums. Any new definition of datums considered by the standards committees should cover all datum feature types used in design and support both traditional metrological methods and new digital measurement techniques. This is a challenging task that requires some careful compromise.

CERT1 mutations perturb human development by disrupting sphingolipid homeostasis.

Neural differentiation, synaptic transmission, and action potential propagation depend on membrane sphingolipids, whose metabolism is tightly regulated. Mutations in the ceramide transporter CERT (CERT1), which is involved in sphingolipid biosynthesis, are associated with intellectual disability, but the pathogenic mechanism remains obscure. Here, we characterize 31 individuals with de novo missense variants in CERT1.

Using Thermal Interface Resistance for Noninvasive Operando Mapping of Buried Interfacial Lithium Morphology in Solid-State Batteries.

The lithium metal-solid-state electrolyte interface plays a critical role in the performance of solid-state batteries. However, operando characterization of the buried interface morphology in solid-state cells is particularly difficult because of the lack of direct optical access. Destructive techniques that require isolating the interface inadvertently modify the interface and cannot be used for operando monitoring.

Validation of an automated machine learning algorithm for the detection and analysis of cerebral aneurysms.

Objective: Machine learning algorithms have shown groundbreaking results in neuroimaging. The authors herein evaluated the performance of a newly developed convolutional neural network (CNN) to detect and analyze intracranial aneurysms (IAs) on CTA.

Methods: Consecutive patients with CTA studies between January 2015 and July 2021 at a single center were identified.

Elucidating the Molecular Origins of the Transference Number in Battery Electrolytes Using Computer Simulations.

The rate at which rechargeable batteries can be charged and discharged is governed by the selective transport of the working ions through the electrolyte. Conductivity, the parameter commonly used to characterize ion transport in electrolytes, reflects the mobility of both cations and anions. The transference number, a parameter introduced over a century ago, sheds light on the relative rates of cation and anion transport.

Improving work life balance among female educationists during the COVID-19 lockdown.

Background: The entire education industry switched from offline to online modes as a result of the coronavirus outbreak. Numerous teachers who were diagnosed with musculoskeletal, psychological, and other neurodegenerative diseases have reported increased exhaustion, lack of sleep, a decline in quality of life (QoL), a decrease in physical activity, and excessive stress from online classes during the COVID-19 lockdown, especially women.

Objective: The aim of this study is to evaluate the effectiveness of three-modal exercise on fatigue, sleep, QoL as well as to determine the relationship between age, disease severity, disease stage and working years with women diagnosed with Parkinson's disease (PD).

Approach Selection Strategies for Repeat Resection of Brain Cavernous Malformations: Cohort Study.

Background: Neurosurgical management of cerebral cavernous malformations (CMs) often benefits from using skull base approaches. Although many CMs are cured by resection, residual or recurrent disease may require repeat resection.

Objective: To review approach selection strategies for reoperation of CMs to aid decision-making for repeat procedures.

Green synthesis of zinc oxide nanoparticles using Brassica oleracea var. botrytis leaf extract: Photocatalytic, antimicrobial and larvicidal activity.

Green synthesis of nanomaterials has emerged as an ecofriendly sustainable technology for the removal of dyes in the last few decades. Especially, plant leaf extracts have been considered as inexpensive and effective materials for the synthesis of nanoparticles. In this study, zinc oxide nanoparticles (ZnO NPs) were prepared using leaves extract of Brassica oleracea var.

Comparison of Various Modalities in the Treatment of Early Knee Osteoarthritis: An Unsolved Controversy.

Introduction Osteoarthritis (OA) of the knee is a common degenerative disease, relatively more prevalent among middle-aged people. It is one of the major reasons for walking-related disability. Recently, early knee OA has been seen as an imperative concern in many younger patients who struggle with the disabling effect of pain and management is extremely speckled.

Socioeconomic Drivers of Outcomes After Aneurysmal Subarachnoid Hemorrhage Treatment at a Large Comprehensive Stroke Center.

Background: Sparse data exist on socioeconomic disparities among patients treated for aneurysmal subarachnoid hemorrhage (aSAH). The authors analyzed factors possibly influencing patient outcomes, including having a primary care physician (PCP) at admission, family/caregiver support, a foreign language barrier, primary payer status, and race.

Methods: Socioeconomic data were abstracted for patients treated endovascularly or microsurgically for aSAH at a single center (January 1, 2014-July 31, 2019).

You Take the Low Road: Differential Outcomes After Tangential and Transcortical Approaches to Medial Temporal Brain Arteriovenous Malformations.

Objective: Microsurgical resection of medial temporal brain arteriovenous malformations (AVMs) is typically conducted through 2 approaches: the orbitozygomatic-tangential and subtemporal-transcortical. Relative indications and outcomes for these techniques have not been formally compared.

Methods: The cerebrovascular database of a quaternary center was reviewed for patients with medial temporal AVMs treated between January 1, 1997, and July 31, 2021.
