Summary
Computer-assisted planning (CAP) for stereotactic brain biopsy offers a safer alternative to manual planning. This automated platform generated more perpendicular trajectories, shorter lengths, and lower risk scores in a pilot study.
Area of Science:
- Neurosurgery
- Medical Imaging
- Computational Anatomy
Background:
- Stereotactic brain biopsy is a common neurosurgical procedure.
- Optimal trajectory planning is crucial for safety, focusing on perpendicular skull traversal, minimized length, and avoidance of neurovascular structures.
Purpose of the Study:
- To evaluate the SurgiNav platform for automated trajectory planning in stereotactic brain biopsy.
Main Methods:
- A prospectively maintained database of adult patients undergoing stereotactic brain biopsy (February-August 2017) was reviewed.
- Preoperative MRI data was used to generate cortical models for computer-assisted planning (CAP).
- CAP-generated trajectories were compared to previously implemented manual plans (MP) using metrics like angle, length, and risk score.
Main Results:
- Feasible trajectories were generated using CAP in all 15 identified patients.
- CAP resulted in trajectories more perpendicular to the skull (10.0° vs 14.6°), shorter mean length (38.5 vs 43.5 mm), and lower risk scores (0.27 vs 0.52) compared to MP.
- Statistical significance was noted for trajectory length (P=.01) and risk score (P=.03).
Conclusions:
- Computer-assisted planning for stereotactic brain biopsy is feasible.
- The SurgiNav platform may enhance safety in selected stereotactic brain biopsy cases.

01:21Pilot and Numeric Relaying
483
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

01:21Planning Nursing Care I
5.6K
The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...

01:29Planning Nursing Care II
3.6K
A nursing care plan can present in two forms: informal and formal. Informal is a care plan for the individual use of the nurse and goals they wish to accomplish during their shift. Informal care plans are not included in the patient chart. A formal nursing care plan is a written or computerized guide that organizes patient care. It is further subdivided into two: standardized and individualized care plans. Standardized care plans are pre-populated care plans for specific patient populations,...

02:26Comparing Copy Number Variations and SNPs
18.6K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

01:20Comparing the Survival Analysis of Two or More Groups
573
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...
