Objective: To test the external validity of the fracture to plafond (FTP-length of fracture/distance to plafond) ratio to rule out distal intra-articular fractures (DIA) in distal tibial shaft fractures at an independent tertiary trauma center.
Design: Retrospective cohort study.
Setting: Two Level 1 trauma centers.
Patients: Two hundred seventeen patients with a distal tibial shaft fracture in the model cohort and 146 patients in the validation cohort.
Intervention: Radiographic measurements to calculate FTP ratio.
Main Outcome Measurements: Calibration plots, area under receiver operating characteristic curve (AUC), and decision curve analyses to evaluate the external validity of FTP ratio to determine DIA.
Results: The AUC for the anteroposterior (AP) FTP ratio was 0.83 [95% confidence interval (CI) 0.78-0.88] in the model data set and 0.86 (95% CI 0.80-0.91) in the validation data set. The AUC for the lateral FTP ratio was 0.82 (95% CI 0.77-0.87) in the model data set and 0.82 (95% CI 0.75-0.88) in the validation data set. The previously established AP FTP cutoff ratio of 0.61 had a 94% negative predictive value in the model cohort and a 100% negative predictive value in the validation cohort.
Conclusion: The FTP ratio is an effective and externally validated screening tool to rule out DIA in distal tibia shaft fractures.
Level Of Evidence: Diagnostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Association Between the Fetal-Type Posterior Cerebral Artery and Hypertensive Thalamic Hemorrhage.

Introduction: This study investigated the association between the fetal-type posterior cerebral artery (FTP) and hypertensive thalamic hemorrhage (HTH).
Method: Patients with hypertension who met the admission criteria between January 2020 and August 2022 were retrospectively analyzed and divided into the HTH and non-HTH groups based on the presence or absence of thalamic hemorrhage, respectively. In addition to whether the variable was an FTP, other variables with unbalanced distributions between the two groups were used as matching factors for 1:1 propensity score matching, and other variables that were not used as matching factors were used as covariates for conditional logistic regression.
Pregnancy-Related Factors and Breast Cancer Risk for Women Across a Range of Familial Risk.
JAMA Netw Open
August 2024
Columbia University Irving Medical Center, New York, New York.
Importance: Few studies have investigated whether the associations between pregnancy-related factors and breast cancer (BC) risk differ by underlying BC susceptibility. Evidence regarding variation in BC risk is critical to understanding BC causes and for developing effective risk-based screening guidelines.
Objective: To examine the association between pregnancy-related factors and BC risk, including modification by a of BC where scores are based on age and BC family history.
Associations between regional blood-brain barrier permeability, aging, and Alzheimer's disease biomarkers in cognitively normal older adults.
PLoS One
June 2024
Helen Wills Neuroscience Institute, University of California, Berkeley, Berkeley, California, United States of America.
Background: Increased blood-brain barrier permeability (BBBp) has been hypothesized as a feature of aging that may lead to the development of Alzheimer's disease (AD). We sought to identify the brain regions most vulnerable to greater BBBp during aging and examine their regional relationship with neuroimaging biomarkers of AD.
Methods: We studied 31 cognitively normal older adults (OA) and 10 young adults (YA) from the Berkeley Aging Cohort Study (BACS).
The relation between persistent foramen tympanicum and degenerative bone alterations in temporomandibular joint region.

Objectives: The aim of this study was to evaluate, using cone-beam computed tomography (CBCT), the relationship of persistent foramen tympanicum (PFT) with degenerative changes in the temporomandibular joint (TMJ) and the presence of pneumatized glenoid fossae and articular eminences.
Method: Two experienced oral and maxillofacial radiologists evaluated 510 CBCT scans, from which 94 patients were divided into two groups: G1-patients with PFT and G2-control group. The location of the PFT, presence, or absence of degenerative TMJ changes and morphology were evaluated.
Effect of fermented tomato pomace on the growth performance, antioxidant capacity, and intestinal microflora in broiler chickens.

Solid-state fermentation is a useful method for the utilization of the agri-industrial residues. This study was conducted to investigate the effects of tomato pomace (TP) and Aspergillus niger-fermented tomato pomace (FTP) on the growth performance, some carcass traits, antioxidant status, and intestinal microflora in broiler chickens. A total of 140 Ross 308 one-day-old male chicks were allocated to one of four treatment groups consisting of five replicates of seven chicks each.
