Retrograde varicocele embolization may be superior to surgery because of its ability to detect gonadal vein variants. In our study group, transcatheter embolization with 3% polidocanol and fibered coils allowed successful, minimally invasive treatment of postsurgical varicoceles.
Values of cIMT were significantly greater in RA compared with control subjects. Features of RA, such as extra-articular manifestations, erosions, high inflammatory parameters, and long disease duration, even in the absence of traditional clinical CV risk factors, were associated with greater cIMT, suggesting an unfavorable CV risk profile.
BackgroundDecreased heat shock protein 27 (HSP27) participates in many processes that are involved in cardiovascular (CV) disease. The objective of the study was to evaluate if HSP27 level was predictive of mortality as well as to evaluate factors associated with HSP27 level in a group of patients treated with HD.MethodsEnrolled to the study were 202 HD patients. Clinical data, biochemical, echocardiographic, and carotid atherosclerosis parameters were evaluated. Patients were splited into groups on the basis of the cut-off lower and higher 50th percentile of serum HSP27 levels, and were followed-up for 28.68 ± 6.12 months.ResultsNo significant difference was observed between serum HSP27 levels in patients and controls. Low HSP27 patients were older, had higher left ventricular mass index, lower ejection fraction, higher prevalence of diabetes, myocardial infarction and carotid atherosclerosis, higher C-reactive protein level, and worse oxidant/antioxidant status. The multiple regression analysis identified that HSP27 levels were independently, negatively associated with serum oxidized LDL and the number of carotid plaques. Using the Kaplan–Meier analysis it was shown that the cumulative incidences of both CV and sudden cardiac death (SCD) mortality were higher in low HSP27 group in comparison with high serum HSP27 group. A multivariate Cox analysis showed that HSP27 level is an independent and strong predictor of CV as well as SCD mortality.ConclusionsLow serum HSP27 level is independently associated with both CV and SCD mortality but not with all-cause mortality. Low serum HSP27 level is associated with carotid atherosclerosis and oxidative stress.
Obesity remains a pandemic of the 21st century. While there are many causes of obesity and potential treatments that are currently known, source data indicate that the number of patients is constantly increasing. Neural mechanisms have become the subject of research and there has been an introduction of functional magnetic resonance imaging in obesity-associated altered neural signaling. Functional magnetic resonance imaging has been established as the gold standard in the assessment of neuronal functions related to nutrition. Thanks to this, it has become possible to delineate those regions of the brain that show altered activity in obese individuals. An integrative review of the literature was conducted using the keywords ““functional neuroimaging” OR “functional magnetic resonance “OR “fmri” and “obesity” and “reward circuit and obesity” in PubMed and Google Scholar databases from 2017 through May 2022. Results in English and using functional magnetic resonance imaging to evaluate brain response to diet and food images were identified. The results from functional magnetic resonance imaging may help to identify relationships between neuronal mechanisms and causes of obesity. Furthermore, they may provide a substrate for etiology-based treatment and provide new opportunities for the development of obesity pharmacotherapy.
Although visceral artery aneurysms are rare, mortality due to their rupture is high, estimated at even 25–75%. That is why it is significant to detect each such lesion. Visceral artery aneurysms are usually asymptomatic and found incidentally during examinations performed for other indications. Autopsy results suggest that most asymptomatic aneurysms remain undiagnosed during lifetime. Their prevalence in the population is therefore higher. The manifestation of a ruptured aneurysm depends on its location and may involve intraperitoneal hemorrhage, gastrointestinal and portal system bleeding with concomitant portal hypertension and bleeding from esophageal varices. Wide access to diagnostic tests, for example ultrasound, computed tomography or magnetic resonance imaging, helps establish the correct diagnosis and a therapeutic plan as well as select appropriate treatment. After a procedure, the same diagnostic tools enable assessment of treatment efficacy, or are used for the monitoring of aneurysm size and detection of potential complications in cases that are ineligible for treatment. The type of treatment depends on the size of an aneurysm, the course of the disease, risk of rupture and risk associated with surgery or endovascular procedure. Endovascular treatment is preferred in most cases. Aneurysms are excluded from the circulation using embolization coils, ethylene vinyl alcohol, stents, multilayer stents, stent grafts and histoacryl glue (or a combination of these methods).
QRS-T is high in PD patients and is mainly associated with coronary artery calcium burden, atherosclerosis and troponin T elevation. The possible clinical importance of the higher QRS-T in PD patients remains to be confirmed in further studies.
Aim: The purpose of this paper was to evaluate the efficacy of ultrasound-guided percutaneous thrombin injection as a treatment method for arterial access site pseudoaneurysm. Materials and methods: A total of 148 patients with iatrogenic arterial access site pseudoaneurysms were treated in the Department of Interventional Radiology and Neuroradiology, Medical University of Lublin. Of those, 142 pseudoaneurysms were located in the common femoral artery, 3 in the brachial artery and the remaining 3 in the radial artery. The study included 77 woman and 71 men (mean age 64.5 ± 14 years). Patients were qualified for percutaneous thrombin injection after Doppler examination during which pseudoaneurysm size and morphology were assessed as well as the presence of arteriovenous fistula was excluded. Results: In the reported study, 94.8% (128/135) of patients were successfully treated during the initial thrombin injection. Additional 400 IU dose of thrombin after 24 hours was effective in 5 out of 7 patients with recanalization during the follow-up. A total of 98.5% (133/135) of patients were successfully treated with a percutaneous ultrasound-guided thrombin injection. Conclusions: The 10-year experience presented in this study as well as literature reports prove that percutaneous ultrasound-guided thrombin injection is an effective and safe treatment method for iatrogenic arterial access site pseudoaneurysm.
Renal artery stenosis is the most common cause of potentially curable secondary hypertension. For a long time, angiography has been considered the "gold standard" in screening for renal arterial occlusive disease, but it is expensive and invasive. Magnetic resonance angiography and spiral computed tomography are safer alternatives to angiography but are expensive and not widely available. Due to the fact that duplex scanning is noninvasive, it has been advocated since the early 1980s as a screening test for renal vascular disorders. Factors that make duplex ultrasound an attractive screening measure for renovascular disease are its safety, suitability for outpatient use, and low cost. However, the frequency of artery variants, lengthy examination time, and technically inadequate test conditions limit the use of the direct duplex ultrasound detection of renal artery stenosis. Advances in Doppler technology may alleviate some of the current problems related to examination of renal arteries. One such technique is the use of echo-enhancing agents, which increase Doppler signal strength and can improve the sensitivity and specificity in Doppler ultrasound detection of renal artery stenosis.
