ABSTRACT
The vascular risk associated with obesity is particularly associated with visceral adiposity, but recent studies suggest that ectopic fat might contribute to the increased risk of atherosclerotic cardiovascular disease. Our study aimed to explore the connection between arterial calcification of the aorta and renal arteries with visceral and ectopic fat deposits, including liver, pancreatic, and renal sinus fat. Retrospective analysis of thoracoabdominal multi-slice computed tomography (MSCT) scans of 302 patients included measurements of calcification volumes of thoracic and abdominal aorta, and of both renal arteries. On the same scans, the visceral fat volume, liver-to-spleen ratio, pancreatic-to-spleen ratio, and both renal sinus fat areas were retrieved. Logistic regression showed the left kidney sinus fat area to be the most strongly associated with calcifications in the aorta and both renal arteries (coef. from 0.578 to 0.913, p < 0.05). The visceral fat positively predicted aortic calcification (coef. = 0.462, p = 0.008), and on the contrary, the pancreatic fat accumulation even showed protective effects on thoracic and abdominal aorta calcification (coef. = -0.611 and -0.761, p < 0.001, respectively). The results suggest that ectopic fat locations differently impact the calcification of arteries, which should be further explored.
ABSTRACT
Visceral and ectopic fat accumulation might have an impact on the atherosclerotic calcification of abdominal arteries. The pattern of calcification of the abdominal aorta and its branches is not fully investigated. We retrospectively analyzed the abdominopelvic MSCT images and calculated calcification volumes of the abdominal aorta, celiac trunk, superior and inferior mesenteric arteries, and both common and external iliac arteries. On the same MSCT scans, a visceral fat volume and ectopic fat deposits (liver-to-spleen ratio (L/S) and pancreas-to-spleen (P/S) ratio) were also measured. The results showed that calcifications of the abdominal aorta and its branches were associated with visceral fat volume, less strongly associated with L/S, and not associated with the P/S ratio. The abdominal aorta, the common iliac and external iliac arteries were more calcified arteries compared to the celiac trunk and superior and mesenterial arteries. In conclusion, visceral fat has a stronger effect on abdominopelvic arteries' calcification than ectopic fat. Visceral aortic branches are generally less calcified than iliac arteries.
ABSTRACT
One of the most powerful influences on the patient is the family and its characteristics. In the recent decades families have changed, one of the most well known changes was a shift from extended to nuclear families. The consequences of this shift on health have been poorly researched, although family factors are being taught at medical schools. The aim of this study is to explore differences and similarities in factors between nuclear and extended families which may affect health and health care of family members. We conducted the qualitative study of family reports. The reports were done by students of family medicine. We examined the reports according to fourtheme: (1) Relations between the members of the family and between them and society, (2) Lifestyle, (3) Use of medical services and confidence in doctors and medicine, (4) Ilnesses and attitude towards illnesses. Differences were found in relations between the closest members of the family, close family interactions, domination issues and family roles, attitudes towards independence, parents and children, interaction with other people, attitude towards medicine, taking care of the sick member of the family and the way families endure illnesses. A quantitative research is needed to verify all the differences which we came across in this study. The qualitative data support the importance of family on health.
