The importance of socio-economic determinants of health in the care of patients with peripheral artery disease: A narrative review from VAS.

Socio-economic determinants of health (SDoH) include various nonmedical factors in the socio-economic sphere with a potentially significant impact on health outcomes. Their effects manifest through several mediators/moderators (behavioral characteristics, physical environment, psychosocial circumstances, access to care, and biological factors). Various critical covariates (age, gender/sex, race/ethnicity, culture/acculturation, and disability status) also interact. Analyzing the effects of these factors is challenging due to their enormous complexity. Although the significance of SDoH for cardiovascular diseases is well documented, research regarding their impact on peripheral artery disease (PAD) occurrence and care is less well documented. This narrative review explores to what extent SDoH are multifaceted in PAD and how they are associated with its occurrence and care. Additionally, methodological issues that may hamper this effort are addressed. Finally, the most important question, whether this association may contribute to reasonable interventions aimed at SDoH, is analyzed. This endeavor requires attention to the social context, a whole systems approach, multilevel-thinking, and a broader alliance that reaches out to more stakeholders outside the medical sphere. More research is needed to justify the power in this concept to improve PAD-related outcomes like lower extremity amputations. At the present time, some evidence, reasonable consideration, and intuitive reasoning support the implementation of various interventions in SDoH in this field.

Acute phase reactant proteins in Buerger's disease: Is it a systemic disease?

Aim: The aim of this study was evaluating acute phase reactant (APR) proteins including high sensitivity C-reactive protein (hsCRP), pentraxin 3 (PTX3), fibrinogen, complement C3, hepcidin, and albumin in patients suffering from Buerger's disease (BD) compared to controls.Methods: The APRs were evaluated in 92 cases of BD patients and 90 healthy age and sex matched controls of blood from Iran and Turkey. The diagnosis was done according to Shionoya's criteria. However, patients with age less than 40 were included, instead of those less than 50. The diagnosis was confirmed by angiography or CT angiography. The patients were categorized into active and quiescent phases of the disease according to clinical manifestation. Patients with rest pain, non-healing ulcer, and gangrene were categorized in the active phase of the disease and the patients with unchanged claudication for more than 6 months without trophic lesions or gangrene were categorized in the quiescent phase of the disease.Results: The serum level of PTX3, hsCRP, fibrinogen, C3, and hepcidin in BD was significantly higher than controls (p < 0.004). Also, albumin in the BD group was significantly lower than controls (p < 0.001). In patients that categorized in the active phase, fibrinogen, C3, and hsCRP were significantly higher and albumin was significantly lower compared to patients in the quiescent phase. No significant difference was found between the level of PTX3 and hepcidin in the patients in active and quiescent phases of the disease.Conclusion: The pattern of the level of APRs in BD seems more likely systemic inflammatory disorder than atherosclerosis obliterans. More clinical trials for evaluating the efficacy of anti-inflammatory medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, and corticosteroids as a part of management of BD are required. Also, according to low level of albumin in TAO, a protein rich diet might be beneficial for BD patients in the active phase of their disease.

An International Delphi Consensus on Diagnostic Criteria for Buerger's Disease.

BACKGROUND: Buerger's disease (BD) remains a debilitating condition. Despite multiple published diagnostic criteria for BD, none is universally accepted as a gold standard. METHODS: We conducted a 2-round modified Delphi consensus study to establish a consensus on the diagnostic. The questionnaire included statements from several commonly used diagnostic criteria for BD. Qualitative and quantitative analysis methods were performed. An agreement level of 70% was applied. RESULTS: Twenty nine experts from 18 countries participated in this study. Overall, 75 statements were circulated in Round 1. Of these, 28% of statements were accepted. Following comments, 21 statements were recirculated in Round 2 and 90% were accepted. Although more than 90% of the experts did not agree that the diagnosis of BD can be based only on clinical manifestation, none of the nonclinical manifestations of BD were agreed as a part of the diagnostic criteria. There was an agreement that a history of tobacco consumption in any form, not necessarily confined to the current use, should be a part of the diagnostic criteria of BD. The history of thrombophlebitis migrans, even if not present at presentation, was accepted as a clue for BD diagnosis. It was also agreed that discoloration of the toes or fingers could be included in the diagnostic criteria of BD. Experts agreed that histology results could differentiate BD from atherosclerosis obliterans and other types of vasculitis. The presence of corkscrew collaterals on imaging and burning pain reached the agreement at the first round but not at the second. There was no consensus regarding age cut-off, the requirement of normal lipid profile, and normal blood glucose for BD diagnosis. CONCLUSIONS: The present study demonstrated discrepancies in the various published diagnostic criteria for BD and their selective utilization in routine clinical practice worldwide. We propose that all published diagnostic criteria for BD be re-evaluated for harmonization and universal use.

Unusual presentation of moyamoya disease with popliteal involvement: case report and review of the literature.

Moyamoya disease is a rare disorder that involves the cerebrovascular system. Usually, it leads to occlusion of the arteries of the cerebral system and causes cerebral circulatory complaints. A 48-year-old female patient was admitted to our clinic with intermittent claudication in both legs. Biphasic and monophasic waveform patterns were detected bilaterally in distal (trifurcation arteries) lower extremities with Doppler sonography. The patient therefore underwent systemic vascular examination. Computed tomography angiography revealed bilateral carotid occlusion at the level of supraclinoid segments, and opacifications were detected at the distal segments of the bilateral anterior cerebellar and middle cerebellar arteries. The patient was diagnosed with moyamoya disease, and anticoagulant treatment was started. In conclusion, most previous reports have presented the cerebrovascular involvement of moyamoya disease. However, this disease can involve different peripheral vascular systems and careful and systemic vascular examination is necessary for an exact diagnosis.

A doença de moyamoya é um distúrbio raro que envolve o sistema cerebrovascular. Normalmente, leva à oclusão das artérias do sistema cerebral e causa problemas circulatórios no cérebro. Uma mulher de 48 anos foi admitida em nossa clínica com claudicação intermitente em ambas as pernas. Na ultrassonografia com Doppler, foram detectados padrões de formato de onda bifásico e monofásico nas extremidades inferiores distais (artérias da trifurcação) de forma bilateral. Portanto, realizou-se o exame vascular sistêmico na paciente. A angiografia por tomografia computadorizada revelou oclusão carotídea bilateral no nível dos segmentos supraclinoides, e opacificações foram detectadas nos segmentos distais das artérias cerebelares anteriores e médias de forma bilateral. A paciente foi diagnosticada com doença de moyamoya, e o tratamento anticoagulante foi iniciado. Em conclusão, a maioria dos relatos anteriores apresentou o envolvimento cerebrovascular da doença de moyamoya. No entanto, essa doença pode envolver diferentes sistemas vasculares periféricos, e um exame vascular sistêmico minucioso é necessário para um diagnóstico exato.

Analysis of routine blood markers for predicting amputation/re-amputation risk in diabetic foot.

Diabetic foot is challenging progressive disease which requires multisystemic control. Neuropathy, arteriopathy, and cellular responses should treated collaboratively. Despite all medical advances, diabetic foot can highly resulted with amputation and also re-amputation can be required because of failed wound healing. In this study, we aimed to investigate the relation between blood parameters and amputation events. Diabetic 323 patients include to the study who referred to orthopaedic clinic for amputation. Amputation levels (amputation levels phalanx, metatarsal, lisfranc, syme, below knee, knee-disarticulation, above-knee amputation) and re-amputations recorded and compared with routine blood parameters. Re-amputation was observed at 69 patients. The significant difference detected between lower albumin, higher HbA1c, higher CRP levels (P < 0.05) in regards to gross amputation levels, and increased wound depth. Furthermore, lower albumin levels and higher levels of WBC, HbA1c, CRP, and Creatinine were detected in re-amputation levels. Especially, HbA1c, CRP, and Creatinine levels were found as upper bound of reference line for re-amputation. The statistically optimal HbA1c cutoff point for diabetes was ≥7.05%, with a sensitivity of 86% and a specificity of 59%. In according to our results, simple blood parameters can be useful for observing the progress of amputation in diabetic foot. Particularly, lower albumin, and higher HbA1c, CRP, and Creatinine levels detected as related with poor prognosis. Besides, screening of HbA1c level seems to be highly sensitive for detecting of re-amputation possibility.

Investigation of the arterial intima-media thickness in Behcet's disease patients without vascular complaints.

Objectives Behcet's disease is a multisystemic, inflammatory disease. Various factors have been implicated in the disease, including genetics, infections, immunoglobulins, immune complexes, antibodies, and oxidative stress. However, the underlying etiopathogenesis remains unclear. Behcet's disease can occur with or without vascular involvement. This prospective study investigated the relationship between the intima-media thickness of the major arteries, in addition to other factors affecting the disease process, in Behcet's disease without vascular involvement. Methods Twenty-four patients (average age: 38.50 ± 10.931) without vascular involvement or any vascular complaints who were diagnosed with Behcet's disease were included in the study. Sixteen healthy subjects (average age: 39.75 ± 7.793) were included as a control group. Demographic information and medical histories were recorded, and routine blood tests were performed in both groups. The intima-media thickness of the subclavian, axillary, femoral, and carotid arteries of all the participants were recorded using Doppler ultrasonography. The data were then subjected to intergroup statistical and correlation analyses. Results There were no significant differences between the arterial intima-media thickness values of the Behcet's disease patients and those of the control group ( p > 0.05). However, there was a significant difference between the neutrophil-lymphocyte ratio ( p = 0.004), low-density lipoprotein ( p = 0.007), and triglyceride ( p = 0042) levels of the two groups. Significant correlations were found between intima-media thickness and neutrophil-lymphocyte ratio levels ( p = 0.012) and the disease duration ( p = 0.030). There was also a significant correlation between the intima-media thickness of the femoral artery and disease duration ( p = 0.014). Conclusions The results showed that the duration of illness had a significant effect on arterial intima-media thickness in Behcet's disease. Blood neutrophil-lymphocyte ratio levels were also associated with increased intima-media thickness.

Evaluation of Pericardial Fluid C-Type Natriuretic Peptide Levels in Patients Undergoing Coronary Bypass Surgery.

Background Neurohumoral and hemodynamic mechanisms have an effect on cardiac activity. C-type natriuretic peptide (CNP) is accessible in the cardiovascular system. The aim of this study was to determine whether CNP concentrations in pericardial fluid and blood are related to cardiac dysfunction in patients undergoing coronary artery bypass graft surgery. Materials and Methods In this study, 40 patients undergoing coronary artery bypass grafting were enrolled. The patients were separated into two groups according to left ventricular (LV) ejection fraction (EF): group 1 contained 28 patients with normal LV systolic function (LVEF ≥ 50%) and group 2 contained 12 patients with impaired LV systolic function (LVEF < 45%). Plasma and pericardial fluid samples were acquired during surgery to measure CNP levels. Results In group 1, CNP levels were detected to be 0.46 ± 0.10 ng/mL in plasma and 0.66 ± 0.8 ng/mL in pericardial liquid. In group 2, these levels were 0.51 ± 0.09 and 0.79 ± 0.12 ng/mL, respectively. CNP levels were determined to be significantly higher in patients with low EF compared with those with normal EF in pericardial fluid concentrations (p = 0.013). Conclusions CNP level in pericardial fluid is a more sensitive and proper marker of LV dysfunction than CNP levels in plasma. To the best of our knowledge, this study is the first to examine pericardial fluid CNP levels in patients undergoing coronary artery bypass surgery. It may have a valuable role in organizing cardiac remodeling and hypertrophy.

Hyperbaric Oxygen Preconditioning Provides Preliminary Protection Against Doxorubicin Cardiotoxicity.

BACKGROUND: Doxorubicin (DOX) is generally recognized to have important cardiotoxic side effects. Studies are contradictory about the interaction between hyperbaric oxygen (HBO2) therapy and doxorubicin-induced cardiomyotoxicity. Recent data suggests that HBO2 therapy can lead to preconditioning of myocardium while generating oxidative stress. Herein we have investigated the effect of HBO2 therapy in a DOX-induced cardiomyocyte injury animal model. METHODS: Twenty-one rats were divided into three equal groups as follows: 1) Group 1 is a control group (without any intervention), used for evaluating the basal cardiac structures and determining the normal value of cardiacs and serum oxidative markers; 2) Group 2 is the doxorubicin group (single dose i.p. 20 mg/kg doxorubicin) for detecting the cardiotoxic and systemic effects of doxorubicin; 3) Group 3 is the doxorubicin and HBO2 group (100% oxygen at 2.5 atmospheric for 90 minutes, daily), for evaluating the effect of HBO2 in doxorubicin induced cardiotoxicity. At the end of the protocols, the hearts were harvested and blood samples (2 ml) were obtained. RESULTS: The doxorubicin treated animals (Group 2) had increased oxidative stress markers (both cardiac and serum) and severe cardiac injury as compared to the basal findings in the control group. Nevertheless, the highest cardiac oxidative stress index was detected in Group 3 (control vs. Group 3, p = 0.01). However, histological examination revealed that cardiac structures were well preserved in Group 3 when compared with Group 2. CONCLUSIONS: Our results suggest that HBO2 preconditioning appears to be protective in the doxorubicin-induced cardiotoxicity model. Future studies are required to better elucidate the basis of this preconditioning effect of HBO2.

The relationship between fibrinogen to albumin ratio and severity of coronary artery disease in patients with STEMI.

OBJECTIVE: Previous studies show that serum fibrinogen levels are established risk factors for coronary artery disease (CAD) and that serum albumin levels are of a higher specificity and sensitivity in ST-elevation myocardial infarction (STEMI). In this study, we sought to evaluate the association between fibrinogen to albumin ratio (FAR) and the extent and severity of CAD evaluated by TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries (SYNTAX) Score (SS) in patients with STEMI. METHODS: A total of 278 patients with STEMI were included in the study. FAR was calculated using specified variables. The extent and severity of CAD were evaluated using the SS. The patients were divided into low- (SS <22) and high- (SS ≥22) risk groups. A Spearman rank correlation coefficient analysis was used for the relationship between FAR and SS. The cutoff points for sensitivity and specificity of FAR in predicting SS were estimated by performing a receiver operator characteristic curve analysis. RESULTS: There were significant differences in the mean age (P=.016), admission serum albumin (P=.041), serum fibrinogen (P<.001), FAR (P<.001), and SS risk groups. Positive correlation was detected between FAR and SS (r=0.458, P<.001). A cutoff level of >87 FAR predicted SS (sensitivity, 70%; specificity, 70%), and an area under the curve of 0.758 serum fibrinogen and albumin level was an independent predictor for SS in patients with STEMI (b=0.039; 95% confidence interval, 0.016-0.062; P=.001 and b=-6.906; 95% confidence interval, -12.284 to -1.527; P=.013, respectively). CONCLUSION: In the present study, we showed that FAR is significantly related to SS in predicting the severity of CAD in patients with STEMI.

Pharmacomechanical thrombolysis with a rotator thrombolysis device in iliofemoral deep venous thrombosis.

OBJECTIVE: Deep venous thrombosis (DVT) is a life-threatening and morbid pathology. This study aimed to investigate the efficacy of an early thrombolysis procedure using a rotator thrombolysis device. METHODS: Sixty-seven patients with acute proximal DVT were enrolled in the study. Patients' data were recorded retrospectively. Initially, an infrarenal retrievable vena cava filter was placed through the femoral vein. Then, a rotator thrombolysis device and a thrombolytic agent injection were applied to the occluded segments of the deep veins by puncturing the popliteal vein. RESULTS: The identified reasons were trauma (43.3%), pregnancy (20.9%), undiagnosed (11.9%), major surgical operation (10.5%), immobilization (7.5%), and malignancy (5.9%). Immediate total recanalization was conducted in all patients, and the leg diameters returned to normal ranges in the early postoperative period. Hospital mortality or severe complications were not detected. CONCLUSION: New thrombolytic devices seem to reduce in-hospital mortality risks and may potentially decrease post-thrombotic morbidity.
