Environmental Pollution and Peripheral Artery Disease

Peripheral artery disease (PAD) of the lower limbs represents one of the most important clinical conditions among vascular disease and can negatively impact quality of life of affected patients, representing also an important socioeconomic burden. Several risk factors predispose to PAD and its complications. Nevertheless, the role of pollution in this context has not been fully evaluated and this article explored the most updated information on epidemiology and environmental pollution in order to hypothesize the possible contribution of air pollution in the onset of PAD. Pollution is an important problem for the global community and has harmful effects on human health and cardiovascular system, and, specifically, particulate matter 10 (PM10) was found significantly associated with PAD

Social capital in chronic disease: an ethnographic study

Chronically ill conditions are particularly difficult to manage because of their impact both on the social and on the corporal sphere to such an extent as to involve a series of problems that negatively alter the quality of life of affected patients. Chronicity has also a considerable ef-fect on social capital. In the current literature, it is known that social capital may contribute to a range of advantages to people health. Chronic Venous Disease (CVD) includes several pathologi-cal alterations of the venous system of the lower limbs that cause a wide range of symptoms and signs. The aim of this study is to explore, with a qualitative approach, the dynamics of social cap-ital within people's experience of CVD and describe the roles of family and friends and the health care system. The method used is based on face-to-face semistructured interviews was performed, following the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Six-teen patients were included: 11 women and 5 men. The results obtained are completely in line with the current literature, which shows a certain difficulty in terms of daily activities, pain management; work-related difficulties; non-coverage of healthcare costs for medications and drugs prescribed. In the context of social capital, the bonding social capital of the patients inter-viewed was more positively perceived in the role of CVD management than by the patients' fami-lies. Another interesting result concerns the total absence of knowledge of patient associations with CVD. Thus, alongside the biographical destruction that CVD entails, there is evidence of the scarce relevance and presence of health policies capable of improving the quality of life of these people not only from a social and medical point of view but also from an economic point of vie

Association between Anthropometric Measurements and Vascular Disease: A Cross Sectional Study

The aim of this article is to assess the most studied anthropometric measurements in a population of patients with vascular disease (VD) such as chronic venous disease (CVD), carotid stenosis (CS), abdominal aortic aneurysm (AAA), and peripheral artery disease (PAD). This is a cross sectional study that recruited consecutive patients with VD (CVD, CS, AAA, PAD) referred to Vascular Surgery Units of two hospitals in the period July 2019–March 2022. Several anthropometric measurements such as height, weight, body mass index (BMI), waist circumference, waist-to-BMI, waist-to-hip ratio (WHR), A Body Shape Index (ABSI), waist-to-stature ratio (WSR) were recorded. In a one-way ANOVA test, no statistical significance for all anthropometric variables were found, but the post hoc analysis performed with Tuckey test, show significant difference for height (p-value: 0.017) and WHR (p-value: 0.005) when compared AAA and CS groups with CVD, respectively. Height seems positively associated with AAA, and negatively associated with CVD. WHR seems positively associated with CS and negatively associated with CVD. Further studies are needed to clarify the role of anthropometric measures as independent predictors for vascular disease onset, progression, and response to treatments

Molecular Determinants of Chronic Venous Disease: A Comprehensive Review

Chronic Venous Disease (CVD) refers to several pathological and hemodynamic alterations of the veins of lower limbs causing a wide range of symptoms and signs with a high prevalence in the general population and with disabling consequences in the most severe forms. The etiology and pathophysiology of CVD is complex and multifactorial, involving genetic, proteomic, and cellular mechanisms that result in changes to the venous structure and functions. Expressions of several genes associated with angiogenesis, vascular development, and the regulation of veins are responsible for the susceptibility to CVD. Current evidence shows that several extracellular matrix alterations (ECM) could be identified and in some cases pharmacologically targeted. This review shows the most up to date information on molecular determinants of CVD in order to provide a complete overview of the current knowledge on this topic. In particular, the article explores the genetic influence, the hormonal influence, ECM imbalance, and histopathology of CVD and the role of endothelial dysfunction in CVD

Social Aspects of Diabetic Foot: A Scoping Review

Diabetic foot ulcer (DFU) is a severe complication of diabetes mellitus (DM). Patients with DFU have increased mortality and morbidity as well as decreased quality of life (QoL). The present scoping review aims to study the social issues of diabetic foot. Following PRISMA guidelines, the review was conducted in two databases (Scopus and Pubmed) with the use of the following keywords: “social aspects and diabetic foot”, “social characteristics and diabetic foot”, “social issues and diabetic foot”, “demographic profiles and diabetic foot”, “social determinants and diabetic foot”, “social capital and diabetic foot”, “social characteristics and gender and diabetic foot”, “social profiles and diabetic foot”, “social relationships and diabetic foot” and “social risk and diabetic foot”, from July to August 2021. Predetermined exclusion and inclusion criteria were selected. Forty-five studies (quantitative and qualitative) were eligible for inclusion in this review. Gender problems, socioeconomic status, social capital, and medical problems were the most important negative variables for diabetic foot. All the included variables reveal that the social impact of diabetic foot is the most important factor for management and prevention, in terms of aggravation and more, of the diabetic foo

Precision medicine and precision nursing. The era of biomarkers and precision health

Precision health, by means of the support of precision medicine and precision nursing, is able to support clinical decision making in order to tailor optimal health-care decisions, around the individual characteristics of patients. The operational arm of precision health is represented by the use of biomarkers that can give useful information about disease susceptibility, exposure, evolution and response to treatment. Omics, imaging and clinical biomarkers are actually studied for their ability to positively impact health-care management. In this article, we try to address the role of biomarkers in the context of modern medicine and nursing with the view of improving patients care

Elevate to Alleviate – Evidence Based Vascular Nursing Study

Background: Venous return in the circulatory system of lower limbs results from the interaction of several mechanisms and reflects the balance between blood inflow and outflow. Blood outflow improves during the lying position especially with leg elevation both in patients with chronic venous disease (CVD) and in healthy subjects in sedentary settings with short-term immobilization. This study evaluated the level of comfort of hospital inpatients, without CVD, lying with a moderate leg elevation during hospital stay. Methods: This was a clinical trial examining 60 consecutive patients referred to vascular surgery, cardiac surgery, and nephrology units. After inclusion, patients were randomly assigned to two groups: A (leg elevation) in which patients were made to lie in the hospital bed with moderate elevation of the legs, and B (no leg elevation) in which patients were made to lie in the hospital bed without leg elevation. Results: The whole population consisted of 40 patients undergoing leg elevation (group A) and 20 without leg elevation (group B). During each day of hospitalization, measurements such as ankle and calf circumference, heart rate, blood pressure, and body temperature were collected. Subjective data such as perceived heaviness in the lower limbs, comfort perception and hours of sleep were also collected. In this study, patients of group A recorded a decrease in calf and ankle circumference (delta in ankle and calf circumference (difference between end of study visit and baseline visit) were significantly decreased in group A vs group B (p< 0.001 for both sides), and patients perceived less leg heaviness and even reported more leg comfort compared to patients of Group B (p< 0.001)). Among patients of group A, the bigger advantage in terms of comfort perception was recorded in patients with 15° leg elevation. Conclusion: Moderate leg elevation during hospital stay seems to effectively improve leg comfort in hospitalized patients

Wound Care Self-Efficacy Assessment of Italian Registered Nurses and Wound Care Education in Italian Nursing Education System: A Cross-Sectional Study

Wounds are a major public health challenge for nurses, and poor wound care has important implications for patients and health care systems. The aim of this study is to assess the Italian registered nurses’ (RNs) perception in the area of wound care, regarding their knowledge, tasks of care delivery, wound management, values, and attitudes, exploring also the previous specific education received during nursing education. An observational online web-based survey was used to assess learning goals and content for wound care education in undergraduate nursing education and the skills and level of self-efficacy in this area during clinical practice. The data were collected between April and May 2022. A total of 210 RNs were interviewed and divided into five national geographic areas. Northwestern RNs showed a better education about the wound care area during university courses: the rate of RNs that did not receive any training in the wound care area was lower than in other Italian geographical areas. Southern RNs presented a better knowledge about factors that expose the wound to becoming chronic, wound drains care, and the ability to assess diabetic foot. This study showed that, in Italy, education in wound care among nursing students is relatively poor, and many skills are achieved during an RN’s career in an empirical way

Th17-Gene Expression Profile in Patients with Chronic Venous Disease and Venous Ulcers: Genetic Modulations and Preliminary Clinical Evidence

Chronic venous disease is a condition globally widespread, resulting in a disabling pathological disorder. The CD4 + Th17+ (Cluster Differentiation 4) lymphocytes represent a regulative factor for innate immunity related to the development of complex diseases. Recently, these mechanisms have been associated with vascular disease. The aim of this work is to validate whether the Th17 response correlates with the development of CVI (Chronic venous insufficiency)and CVLUs (chronic venous limbs ulcers) and whether Th17 markers can be used, both as intrinsic risk factors and diagnostic markers, for disease development. PBL derived from peripheral blood samples of patients and controls were subjected to gene expression analysis for IL23R, IL17, SGK1, TGFβ, RORγ, FOXO1, and RANBP1 by qRT-PCR and immunoblot. A post hoc correlation, the diagnostic performance of the target genes, and multivariable analyses were properly conducted. The main expression markers of the CD4 + Th17+ switch were strongly activated in chronic venous insufficiency and in advanced ulceration. The correlation analysis demonstrated the inter-dependence on Th17’s signature modulation. ROC (Receiver Operating Characteristic) analysis defined, for the examined genes, a clinical value as the potential diagnostic markers. Multi-logistic regression studies showed that Th17 markers behave as empirical risk factors for CVD (chronic venous disease) development. Taken together, the present data provide a new hypothesis for the TH17-dependent pathogenesis of CVD, favoring the possibility for the development of new diagnostic, preventive, and therapeutic approaches

Aortic aneurysms, chronic kidney disease and metalloproteinases

Metalloproteinases (MPs) are proteolytic enzymes involved in extracellular matrix deposition, regulation of cellular signals of inflammation, proliferation, and apoptosis. Metalloproteinases are classified into three families: Matrix-MPs (MMPs), A-Disintegrin-and-Metalloprotease (ADAMs), and the A-Disintegrin-and-Metalloproteinase-with-Thrombospondin-1-like-Domains (ADAMTS). Previous studies showed that MPs are involved in the development of aortic aneurysms (AA) and, concomitantly, in the onset of chronic kidney disease (CKD). CKD has been, per se, associated with an increased risk for AA. The aim of this review is to examine the pathways that may associate MPs with CKD and AA. Several MMPs, such as MMP-2, -8, -9, and TIMP-1 have been shown to damage the AA wall and to have a toxic effect on renal tubular cells, leading to fibrosis. Similarly, ADAM10 and 17 have been shown to degrade collagen in the AA wall and to worsen kidney function via pro-inflammatory stimuli, the impairment of the Renin-Angiotensin-Aldosterone System, and the degradation of structural proteins. Moreover, MMP-2 and -9 inhibitors reduced aneurysm growth and albuminuria in experimental and human studies. It would be important, in the future, to expand research on MPs from both a prognostic, namely, to refine risk stratification in CKD patients, and a predictive perspective, likely to improve prognosis in response to targeted treatments
