Visceral segment aortic thrombus is associated with proximal aortic degeneration after infrarenal abdominal aortic aneurysm repair

CONCLUSIONS: Visceral aortic thrombus present prior to abdominal aortic aneurysm repair and endovascular repair are both associated with an increased risk of future proximal aortic degeneration after infrarenal abdominal aortic aneurysm repair. These factors may predict patients at higher risk of developing proximal aortic aneurysms that may require complex aortic repairs.PMID:34165017 | DOI:10.1177/17085381211021282

AbstractIn tracheal tissue engineering, the construction of tracheal scaffolds with adequate biodegradable mechanical capacity and biological functions that mimic the structure of a natural trachea is challenging. To explore the feasibility of preparing biomimetic degradable scaffolds with C-type cartilage rings and an inner tracheal wall of polycaprolactone and silk fibroin. A mold was made according to the diameter of a rabbit trachea, and a silk fibroin tube and polycaprolactone ring attached to the tube were obtained by solution casting. The ring was fixed to the tube at a specific spacing using electrostatic spinning ...

AbstractAccurate staging and re-staging of cancer in children is crucial for patient management. Currently, children with a newly diagnosed cancer must undergo a series of imaging tests, which are stressful, time-consuming, partially redundant, expensive, and can require repetitive anesthesia. New approaches for pediatric cancer staging can evaluate the primary tumor and metastases in a single session. However, traditional one-stop imaging tests, such as CT and positron emission tomography (PET)/CT, are associated with considerable radiation exposure. This is particularly concerning for children because they are more sensi...

AbstractThe olfactory tubercle (OT), an important component of the ventral striatum and limbic system, is involved in multi-sensory integration of reward-related information in the brain. However, its functional roles are often overshadowed by the neighboring nucleus accumbens. Increasing evidence has highlighted that dense dopamine (DA) innervation of the OT from the ventral tegmental area (VTA) is implicated in encoding reward, natural reinforcers, and motivated behaviors. Recent studies have further suggested that OT subregions may have distinct roles in these processes due to their heterogeneous DA transmission. Curren...

The objectives of this study were (1) to characterize the effect of T2DM on microdamage quantity and morphology in cancellous bone, and (2) relate the accumulation of microdamage to the cancellous microarchitecture. Cancellous specimens from the femoral neck were collected during total hip arthroplasty (T2DM: n  = 22, age = 65+ 9  years, HbA1c = 7.00+ 0.98%; Non-DM: n  = 25, age = 61+ 8  years, HbA1c = 5.50+ 0.4%), compressed to 3% strain, stained with lead uranyl acetate to isolate microdamage, and scanned with micro-computed tomography. Individual ...

Online ahead of print.ABSTRACTStaff occupational radiation exposure is limited to 20 mSv annually to preclude tissue reaction and lower risk of cancer effect. Staff occupational exposure arises during the preparation, injection, and scanning of the patients. Recent studies reported that nuclear medicine personnel might exceed the annual dose limit in high workload and poor radiation protection circumstances. Therefore, an accurate estimation of the annual dose limit is recommended. The goal of this research is to calculate the cumulative external...

This study aims to describe the trend in preoperative localization techniques for surgical management of primary hyperparathyroidism using career data from two endocrine surgeons over the last 20 years.METHODS: Parathyroid case data was obtained from two endocrine surgeons spanning two institutions from 2000-2018. Demographic and clinical data was obtained for each patient at the time of surgery, including record of any preoperative imaging performed. Data was analyzed temporally using four 5-year periods to evaluate changes in imaging utilization over time.RESULTS: 1734 patients were identified who underwent parathyroidec...

A 61-year-old male presented to our Accident&Emergency department with a three-day history of nausea and vomiting. On examination, he had a soft non-tender abdomen but pronounced pulsation of his abdominal aorta. A CT angiogram revealed a 6 cm juxta-renal abdominal aortic aneurysm with thrombus within the aneurysm sac and juxta-renal neck segment. There was also moderate atherosclerotic change of the common, internal and external iliac arteries bilaterally. Given the lack of a suitable infra-renal sealing zone for the stent graft, he underwent a complex endovascular aortic aneurysm repair using a stent graft (Cook Medi...
