Article Abstract
Introduction: Spinal fractures in fused spines such as in ankylosing spondylitis or DISH are typically of type B or C fractures where operative treatment is recommended. The mortality rate in non-operatively treated patients is reported to be 51%. The purpose of this study was to investigate the mortality rate, complication rate and demographics of patients following non-operatively treatment in fused spine injuries.
Methods: Between 2019 and 2021, a retrospective study was conducted including all patients who presented to our trauma center with a spinal fracture of a fused spine. Radiology and patient charts were analyzed for fracture pattern, complications, neurological deficit, comorbidities, and mortality rate.
Results: A total of 49 patients were found at a mean age was 79.8 ± 10.9 years and primarily males were affected in 65.3%. All fractures were of type B and the thoracic spine was involved in 85.7%. The mean follow-up was 6.3 ± 8.2 months and fusion was obtained in all patients. No neurological deficit was observed in any. A total of 13 patients died at a mean age of 86.5 ± 10.0 years after 157.1 ± 158.1 days. 6 patients (10.2%) deceased within the first 6 weeks at a mean age of 91.8 ± 3.8 years. One patient each suffered from heart failure, an acute delirium, end stage colon cancer and subdural hemorrhage.
Conclusion: This study shows that the mortality rate in the first 6 weeks following a fracture in a fused spine is 10.2% for patients above the age of 90 years. Therefore, non-operative treatment should be taken into consideration as the mortality rate in other studies may be overestimated.
Gastric cancer remains a leading cause of cancer-related mortality worldwide. The prognosis often depends on early detection and understanding the molecular mechanisms involved in its progression. Periodic tryptophan protein 1 (PWP1) has emerged as a novel diagnostic marker, potentially linked to gastric cancer progression.
Atrazine is a predominant herbicide globally, and its residues are commonly found in natural water bodies due to its extensive use. Atrazine is known for its detrimental effects on the reproductive abilities of aquatic plants and animals. Our study explored the impact of maternal exposure to atrazine on the survival and performance of offspring using the water flea Daphnia magna as a model organism.
One Health approaches emphasize intersections between animal health, environmental well-being and human health. Unfortunately, one health approaches rarely explicitly encompass occupational health and safety. This short report provides a concise introduction to the One Health principle, highlighting its potential relevance to improving occupational health and safety in aquaculture.
Antimicrobial resistance is a significant cause of mortality globally due to infections, a trend that is expected to continue to rise. As existing treatments fail and new drug discovery slows, the urgency to develop novel antimicrobial therapeutics grows stronger. One promising strategy involves targeting bacterial systems exclusive to pathogens, such as the transcription regulator protein GabR.
Colorectal cancer (CRC) is a significant contributor to cancer-related mortality, emphasizing the need for advanced biomarkers to guide treatment. As part of an international consortium, we previously categorized CRCs into four consensus molecular subtypes (CMS1-CMS4), showing promise for outcome prediction. To facilitate clinical integration of CMS classification in settings where formalin-fixed paraffin-embedded (FFPE) samples are routinely used, we developed NanoCMSer, a NanoString-based CMS classifier using 55 genes.
