Abstract

The association between uterine smooth muscle fibroids and systemic arterial hypertension is poorly understood. Therefore, we explored possible concomitant myocyte pathology of systemic resistance-sized arterioles (200 to 400 μm), isolated from omental samples donated by 19 women (mean age 42 y; SE 1) undergoing fibroid surgery. Vessels of 17 women (8 hypertensives) were available for transmission electron microscopy. We found ultrastructural vessel wall abnormalities in all patients, albeit with greater severity in hypertensives. In the endothelium, this ranged from moderate mitochondrial and endoplasmic reticulum stress in normotensives, to necrosis and sloughing in hypertensives. Myocyte-like cells were observed to migrate across the internal elastic lamina, with isolated subendothelial myocytes in normotensives, and focal subendothelial multicellular aggregates or myo-intimal "cushions" in hypertensives. Medial myocytes of all patients showed abnormalities similar to fibroids, with dilated sarco-endoplasmic reticulum, elongated mitochondria, and myofilament loss involving focal areas or entire cells. To our knowledge, the first study on the ultrastructure of systemic resistance arterioles of women with fibroids indicates that severe abnormalities are present that likely affect blood pressure regulation. Whether these perturbations are induced by fibroids, or represent systemic pathology that affects myocytes of both uterine and vascular tissue warrants further exploration.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 June 2023.
All research outputs
#14,807,064
of 23,983,331 outputs
Outputs from Ultrastructural Pathology
#140
of 310 outputs
Outputs of similar age
#207,196
of 446,075 outputs
Outputs of similar age from Ultrastructural Pathology
#3
of 10 outputs
Altmetric has tracked 23,983,331 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 310 research outputs from this source. They receive a mean Attention Score of 2.4. This one has gotten more attention than average, scoring higher than 54% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 446,075 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 51% of its contemporaries.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
