Twenty-four refrigeration trials at temperatures ranging from minus 13 degrees C to minus 195.8 degrees C were carried out on trichinous porcine meat samples ranging in size from 120 gm to 11 kg. The findings reaffirmed that Canadian regulations regarding refrigeration treatment of pork and pork products to destroy trichinae are satisfactory. Results also demonstrated the presence of a critical temperature about minus 30 degrees C below which trichinae in meat do not survive for any appreciable period of time.

High Preoperative T1 Slope is a Marker for Global Sagittal Malalignment.
Clin Spine Surg
January 2025
Department of Orthopedic Surgery, NYU Langone Health, New York, NY.
Article Synopsis
- The study analyzed preoperative data from adult spinal deformity patients to establish a threshold for T1 slope (T1S) from cervical radiographs that indicates thoracolumbar malalignment.
- Researchers found a specific cutoff of 30 degrees for high T1S, with 50% of the patients falling above this threshold.
- Notably, higher T1S was linked with greater thoracic kyphosis, sagittal vertical axis, T1-pelvic angle, and pelvic tilt, suggesting that this measurement could serve as a useful parameter in cervical evaluations.

Centrosomes organize microtubules that are essential for mitotic divisions in animal cells. They consist of centrioles surrounded by pericentriolar material (PCM). Questions related to mechanisms of centriole assembly, PCM organization, and spindle microtubule formation remain unanswered, partly due to limited availability of molecular-resolution structural data inside cells.

J Med Internet Res
December 2024
Department of Biostatistics, School of Public Health, Virginia Commonwealth University, Richmond, VA, United States.
Background: The performance of a classification algorithm eventually reaches a point of diminishing returns, where the additional sample added does not improve the results. Thus, there is a need to determine an optimal sample size that maximizes performance while accounting for computational burden or budgetary concerns.
Objective: This study aimed to determine optimal sample sizes and the relationships between sample size and dataset-level characteristics over a variety of binary classification algorithms.
Effect of agreement between clinician-rated and patient-reported PTSD symptoms on intensive outpatient treatment outcomes.
Psychiatry Res
January 2025
Department of Psychiatry and Behavioral Sciences, Emory University School of Medicine, 12 Executive Park Drive NE, 3rd Floor, Atlanta, GA, 30329, United States. Electronic address:
Article Synopsis
- The study examined the agreement between self-reported PTSD symptom severity (PCL-5) and clinician-rated severity (CAPS-5) among US Veterans and service members, aiming to predict treatment improvement post-Intensive Outpatient Treatment Program (IOP).
- Participants were categorized into three groups based on their reporting consistency: Congruent reporters, Limited Over-reporters, and Extensive Over-reporters.
- Findings revealed that Extensive Over-reporters experienced the greatest reduction in PTSD symptoms after treatment compared to the Congruent and Limited Over-reporters, suggesting that understanding these reporting differences can enhance personalized PTSD treatment strategies.
Association of Hemoglobin Decrement During Hospitalization with Prognosis of Aneurysmal Subarachnoid Hemorrhage and Mediation Effects of Cerebral Infarction and Pneumonia.
Int J Gen Med
November 2024
Department of Neurosurgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing, People's Republic of China.
Background: Hemoglobin decrement is a common complication after aneurysmal subarachnoid hemorrhage (aSAH) and is associated with poor outcome. However, the mediating variables on the causal pathway between hemoglobin decrement and poor outcome in aSAH are not clear.
Methods: This is a single-center retrospective observational study containing all consecutive patients with aSAH admitted to our hospital between January 1, 2019, and June 30, 2022.
