RESUMEN

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) have been studied so far as prognostic factors of cardiovascular diseases. Their role interplayed with endothelial inflammation has emerged as optimal predictors for major cardiovascular disease events and prognostic factors for post-procedural outcomes. METHODS: A review of the current literature was undertaken to investigate the relationship between NLR and PLR with percutaneous, cardiac surgery, and vascular surgery procedures. RESULTS: Our findings show that perioperative NLR and PLR levels are significantly correlated with patient morbidity and mortality rates. CONCLUSION: These biomarkers have several attractive characteristics, as they are inexpensive and quickly available, and they can contribute to the early identification of patients at high risk for periprocedural adverse events.

RESUMEN

BACKGROUND: Shaggy aorta (SA) depicts the severe aortic surface degeneration, extremely friable, and likely to cause spontaneous peripheral and visceral embolization or during catheterization, aortic manipulation, surgery, or minimally invasive procedures. This study aims to provide the most accurate and up-to-date information on this disease. METHODS: Potentially eligible studies to be included were identified by searching the following databases: CENTRAL Library, ClinicalTrials.gov, MEDLINE, and CINAHL, using a combination of subject headings and text words to identify relevant studies: (Shaggy aorta) OR (aortic embolization) OR (aortic embolism) OR (aortic thrombus) OR (aortic plaque). From a total of 29,111 abstracts, and after applying inclusion and exclusion criteria, we considered 60 studies for inclusion in this review. RESULTS: Appropriate measurement and assessment of the aortic wall are pivotal in the modern era, in particular when percutaneous procedures are performed, as SA has been identified as an independent risk factor for spinal cord injury, mesenteric embolization, and cerebral infarction after endovascular aortic repair. Furthermore, SA increases the rate of cerebral complications during transcatheter aortic valve implantation. CONCLUSIONS: In conclusion, prompt diagnosis of SA syndrome and appropriate guidelines on the management of these conditions may help physicians to better assess the patient risk and to minimize the dreadful-related complications.

RESUMEN

BACKGROUND: Breast cancer is the most common cancer in women. However, in the management of breast cancer, paraneoplastic neurological syndromes represent a diagnostic and therapeutic challenge. The diagnosis of paraneoplastic neurological syndromes is difficult due to the heterogeneity of symptoms, the timing of presentation, and the absence of antibodies, and it generally occurs before the diagnosis of breast cancer in 80% of patients who develop paraneoplastic neurological syndromes. We describe a 72-year-old woman with subacute ophthalmoplegia-ataxia syndrome who was subsequently diagnosed as having breast cancer and anti-Ri antibodies. CASE PRESENTATION: A 72-year-old post-menopausal Caucasian woman, with a positive medical history for diabetes mellitus and hypertension, presented with a 3-month onset of blurred vision, diplopia, and progressive gait disturbance. Serological tests were positive for well-characterized onconeural antibodies (anti-Ri). A whole-body computed tomography scan revealed a nodular opacity under her left nipple and axillary adenopathy. A biopsy of her left breast was performed, and histological examination showed ductal carcinoma. She underwent a superoexternal quadrantectomy with left axillary dissection. The final diagnosis showed infiltrating ductal carcinoma of the breast (T1c N1 M0, stage IIA) associated with paraneoplastic ophthalmoplegia-ataxia syndrome. At a 6-month follow-up, she showed no clinical or instrumental evidence of neoplastic recurrence with partial clinical improvement of neurological symptoms, such as ataxia and diplopia. CONCLUSION: The diagnosis of paraneoplastic neurological syndromes is often late, as in this patient, but treatment at an early stage may provide a good prognosis. Furthermore, this is one of several cases of an anti-Ri paraneoplastic neurological syndrome not associated with myoclonus, which reinforces the belief that opsoclonus myoclonus syndrome is not pathognomonic of the associated anti-Ri paraneoplastic neurological syndromes.

RESUMEN

Peripheral arterial disease (PAD) and its most severe form, critical limb ischaemia (CLI), are very common clinical conditions related to atherosclerosis and represent the major causes of morbidity, mortality, disability, and reduced quality of life (QoL), especially for the onset of ischaemic chronic leg ulcers (ICLUs) and the subsequent need of amputation in affected patients. Early identification of patients at risk of developing ICLUs may represent the best form of prevention and appropriate management. In this study, we used a Prediction System for Chronic Leg Ulcers (PredyCLU) based on fuzzy logic applied to patients with PAD. The patient population consisted of 80 patients with PAD, of which 40 patients (30 males [75%] and 10 females [25%]; mean age 66.18 years; median age 67.50 years) had ICLUs and represented the case group. Forty patients (100%) (27 males [67.50%] and 13 females [32.50%]; mean age 66.43 years; median age 66.50 years) did not have ICLUs and represented the control group. In patients of the case group, the higher was the risk calculated with the PredyCLU the more severe were the clinical manifestations recorded. In this study, the PredyCLU algorithm was retrospectively applied on a multicentre population of 80 patients with PAD. The PredyCLU algorithm provided a reliable risk score for the risk of ICLUs in patients with PAD.

RESUMEN

BACKGROUND: Biofilm is a fundamental component in the pathogenesis of infections related to the use of the central venous catheter (CVC,) which can represent an important health issue in everyday practice of nursing and medical staff. OBJECTIVE: The objective of the following review is to analyze the components of biofilm and their role in catheter-related infection determinism in an evidencebased nursing perspective in such a way as to give health professionals useful suggestions in the prevention and management of these complications. METHODS: The following databases were consulted for the bibliographic search: Medline, Scopus, Science Direct. Biofilm can be the cause of CVC extraction and can lead to serious haematogenic infectious complications that can increase the morbidity and mortality of affected patients. RESULTS: Updated pathophysiologic knowledge of biofilm formation and appropriate diagnostic methodology are pivotal in understanding and detecting CVC-related infections. Lock therapy appears to be a useful, preventive, and therapeutic aid in the management of CVCrelated infections. New therapies attempting to stop bacterial adhesion on the materials used could represent new frontiers for the prevention of CVC-related infections. CONCLUSION: The correct evidence-based nursing methods, based on the use of guidelines, provides the opportunity to minimize the risks of infection through the implementation of a series of preventive measures both during the CVC positioning phase and in the subsequent phase, for example, during device management which is performed by medical and nursing staff.

RESUMEN

Introduction: Varicose veins are a common disease, causing significant impairment of quality of life to afflicted individuals. Conventional surgery has represented the traditional treatment for years, with significant post-operative complications. By the end of the 20th century, novel approaches had been developed to induce biochemical sclerosis into the treated vein in order to exclude it from blood circulation.Areas covered: Foaming techniques for treatment of varicose veins, both clinically-approved methods and those under experimental studies. A brief description of cavitation, which is the basis of microbubbles formation, and an overview of foam properties have been also provided, including a discussion on clinical efficacy and safety profile.Expert commentary: Foam sclerotherapy has rapidly gained popularity since it represents the most minimally invasive and cost-effective procedure in the short term. Several different methods of foam preparation have been described in literature. In general, the foam generation method may affect characteristics such as stability and bubble size distribution, which in turn affect the therapeutic action of foam itself. Therefore, the selection of a suitable foaming technique is of importance for treatment success. Future developments on foaming techniques are expected to make sclerotherapy, already an effective treatment, even safer and more versatile therapeutic procedure.

RESUMEN

BACKGROUND: Colorectal cancer is one of the most common invasive cancers, and it is responsible for considerable physical and psychosocial morbidity specially in older patients. However, only few reports focused on quality of life, cost-effectiveness and clinical outcomes of rectal cancer patients undergone to surgery. This retrospective study compares short-term and long-term outcomes in rectal cancer patients with more and less than 75 years of age. METHODS: Four hundred consecutive patients underwent radical surgery for rectal adenocarcinoma and they were collected in a prospective institutional database and divided into two groups: group 1 (≥75 years, N.=98); group 2 (<75 years, N.=302). Rectal anterior resection (RAR) with sphincter-saving restorative proctectomy and with application of silicone transanal tube NO COIL® 60-80 mm long, was the only procedure considered. Main clinical and pathological data were assessed and compared. RESULTS: Statistically significant differences between the two groups were detected regard to comorbidities and the emergency presentation. Overall survival is lower in patients over 75 age, but cancer-related survival is not different between the two groups. CONCLUSIONS: Although advanced age is associated with higher morbidity and mortality, in our experience, itself is not a contraindication for surgical sphincter-saving proctetomy in rectal cancer patients. The absence of a stoma also improved the cost effectiveness and patients' quality of life in both groups: psychological morbidity, sexuality, levels of anxiety and depression, body image.

RESUMEN

INTRODUCTION: Rupture of abdominal aortic aneurysm remains a fatal event in up to 65% of cases and emergency open surgery (ruptured open aneurysm repair or rOAR) has a great intraoperative mortality of about 30-50%. The introduction of endovascular repair of abdominal aortic aneurysm (ruptured endovascular aneurysm repair or rEVAR) has rapidly challenged the conventional approach to this catastrophic event. The purpose of this systematic review is to compare the outcomes of open surgical repair and endovascular interventions. EVIDENCE ACQUISITION: A literature search was performed using Medline, Scopus, and Science Direct from August 2010 to March 2017 using keywords identified and agreed by the authors. Randomized trials, cohort studies, and case-report series were contemplated to give a breadth of clinical data. EVIDENCE SYNTHESIS: Ninety-three studies were included in the final analysis. Thirty-five (50.7%) of the listed studies evaluating the within 30 days mortality rates deposed in favor of rEVAR, while the others (comprising all four included RCTs) failed detecting any difference. Late mortality rates were found to be lower in rEVAR group in seven on twenty-seven studies (25.9%), while one (3.7%) reported higher mortality rates following rEVAR performed before 2005, one found lower incidence of mortality at 6 months in the endovascular group but higher rates in the same population at 8 years of follow-up, and the remaining (66.7%) (including all three RCTs) failed finding any benefit of rEVAR on rOAR. A lower incidence of complications was reported by thirteen groups (46.4%), while other thirteen studies did not find any difference between rEVAR and rOAR. Each of these two conclusions was corroborated by one RCTs. Other two studies (7.2%) found higher rates of tracheostomies, myocardial infarction, and acute tubular necrosis or respiratory, urinary complications, and acute renal failure respectively in rOAR group. The majority of studies (59.0%, 72.7%, and 89.3%, respectively) and all RCTs found significantly lower rates of length of hospitalization, intensive care unit transfer, and blood loss with or without transfusion need in rEVAR group. The large majority of the studies did not specified neither the type nor the brands of employed stent grafts. CONCLUSIONS: The bulk of evidence regarding the comparison between endovascular and open surgery approach to RAAA points to: 1) non-inferiority of rEVAR in terms of early (within 30 days) and late mortality as well as rate of complications and length of hospitalization, with trends of better outcomes associated to the endovascular approach; 2) significantly better outcomes in terms of intensive care unit transfer and blood loss with or without transfusion need in the rEVAR group. These conclusions reflect the results of the available RCTs included in the present review. Thus rEVAR can be considered a safe method in treating RAAA and we suggest that it should be preferred when technically feasible. However, more RCTs are needed in order to give strength of these evidences, bring to definite clinical recommendations regarding this subject, and assess the superiority (if present) of one or more brands of stent grafts over the others.

RESUMEN

BACKGROUND AND OBJECTIVES: Foam sclerotherapy is a clinical procedure for the treatment of unhealthy veins. The aim of this study was to investigate the effect of sulodexide (SUL) on stability of foams prepared using polidocanol (POL) and sodium tetradecyl sulfate (STS) detergents, more specifically with 0.25% aethoxysclerol and 0.2% Fibro-Vein sclerosing solutions. METHODS: Foams were produced by the Tessari method using three different weight ratios of POL-SUL and STS-SUL (1:0, 1:1, and 1:3). RESULTS: The half-life of STS foams resulted as follows: 82 ± 1.6 s, 101.8 ± 2.6 s, and 109.7 ± 2.1 s for 1:0, 1:1, and 1:3 STS-SUL weight ratios, respectively. The same ratios were used for POL foams with the following results: 90.6 ± 3 s, 106.8 ± 2.6 s, and 107.6 ± 2.7 s for 1:0, 1:1, and 1:3 POL-SUL weight ratios, respectively. CONCLUSION: The addition of SUL in sclerosing solutions can prolong the half-life of foams, and it could be potentially used as a foam stabilizer.

RESUMEN

Vascular pathology of the lower limbs is a widespread disease affecting the quality of life for more than 30% of the adult world population. Polydocanol foam is presently the main therapeutic option for treating varicosities, inflammation, and chronic disease which affect the vascular endothelium and blood vessels. Unfortunately, the commercial product contains detergents and surfactants which can provoke several side effects and decrease the efficacy of therapy. In an attempt to overcome these drawbacks, polydocanol foam was mixed with different liposomes before use. The resulting mixture was stable and generated supramolecular nanoconstructs, which may prevent the interaction of the components of the commercial polydocanol foam with the vascular endothelium. This effect depends on the presence of liposomes, which can induce polydocanol foam to change its structure from micelles to complex nanostructures, thus improving its stability. In this attempt, the physicochemical features of the resulting nanoconstructs were tested through dynamic- and multiple light scattering analyses, rheological studies and gel permeation chromatography, while the stability was tested in biological fluids. Our preliminary results showed that the nanoconstructs have some potential as therapeutic agents in sclerotherapy.

RESUMEN

Cardiovascular disease refers to different diseases involving the heart and/or the arteries and/or the veins. Cardiovascular disease, overall considered, is a notable source of morbidity and mortality worldwide. Therefore, several research studies are dedicated to explore, by means of biomarkers, the possiblity to calculate the cardiovascular risk both for the onset and for the complications of the related clinical manifestations such as coronary artery disease, carotid artery stenosis, peripheral artery disease, arterial aneurysm, chronic venous disease and venous thromboembolism. This review discusses the most updated information in the area of the novel biomarkers related to omics, imaging techniques and clinical data, that may help physicians in order to improve the knowledge and the management of the cardiovascular risk.

RESUMEN

Varicose veins (VVs) and varicose ulceration (VU) are usually considered non-life-threatening conditions, but in some cases they can lead to major complications such as fatal bleeding. The aim of this systematic review is to evidence the most updated information on bleeding from VV and VU. As evidence acquisition, we planned to include all the studies dealing with "Haemorrhage/Bleeding" and "VVs/VU". We excluded all the studies, which did not properly fit our research question, and with insufficient data. As evidence synthesis, of the 172 records found, after removing of duplicates, and after records excluded in title and abstract, 85 matched our inclusion criteria. After reading the full-text articles, we decided to exclude 68 articles because of the following reasons: (1) not responding properly to our research questions; (2) insufficient data; the final set included 17 articles. From literature searching, we identify the following main issues to be discussed in the review: epidemiology and predisposing factors, pathophysiology and forensic aspects, first aid. It has been estimated that deaths for bleeding due to peripheral venous problems account up to 0.01% of autopsy cases. From a pathological point of view, venous bleeding may arise from either acute or chronic perforation of an enlarged vein segment through the weakened skin. From a forensic point of view, in cases of fatal haemorrhage the death scene can even simulate non-natural events, due to crime or suicide. In most cases, incorrect first aid led to fatal complications. Further investigation on epidemiology and prevention measures are needed.

RESUMEN

INTRODUCTION: Stroke is one of the major causes of death in the world, but above all is the condition most associated with severe long-term disabilities. It is clear that this condition therefore requires the best therapeutic approach possible to minimize the consequences that this can lead to. The major issues concern the type of treatment to be used for revascularization (carotid endarterectomy [CEA] or stenting of the carotid artery [CAS]) and the timing of the treatment itself. Many studies have been conducted on this issue, but a definitive and unanimous verdict has not yet been reached on account of the great variety of results obtained from the various study group. The aim of this review is to analyze the latest scientific findings focused on revascularization following a symptomatic carotid stenosis (SCS). EVIDENCE ACQUISITION: We searched all publications addressing treatments and timing of approach to SCS. Randomized trials, cohort studies and reviews were contemplated in order to give a breadth of clinical data. Medline and Science Direct were searched from January 2013 to April 2017. EVIDENCE SYNTHESIS: Of the 819 records found, 76 matched our inclusion criteria. After reading the full-text articles, we decided to exclude 54 manuscripts because of the following reasons: 1) no innovative or important content; 2) insufficient data; 3) no clear potential biases or strategies to solve them; 4) no clear endpoints; and 5) inconsistent or arbitrary conclusions. The final set included 22 articles. CONCLUSIONS: CEA is considered a less problematic method than CAS, especially for patients over the age of 75; CAS remains recommended in patients with a favorable anatomy or high surgical risks. Studies that showed more solid results seem to lead to the conclusion that optimal timing may be between 2 days and the end of the first week from the onset of symptoms in patients who are appropriate candidates for surgery.

RESUMEN

BACKGROUND: Choledocholithiasis occurs in 10-15% of patients with cholecystolithiasis. Despite the existence of many therapeutic options for the treatment of cholecystocholedocholithiasis, a sequential treatment in which pre-operative ERCP is combined with intraoperative cholangiography (IOC) and laparoscopic cholecystectomy (LC), is the most commonly accepted strategy. However, use of IOC in the "splitting treatment" of cholecystocholedocholithiasis is controversial. The aim of the present study is to investigate the utility of IOC in detecting residual stones in patients undergoing LC in the sequential treatment of common biliary duct or gallbladder stones. METHODS: Patients were recruited retrospectively among those who underwent IOC during LC, performed as second stage in the sequential treatment for cholecystocholedocholithiasis between 2010 and 2016. Demographic and clinical data were obtained from CPT codes at Ospedale Monaldi A.O.R.N dei Colli Naples, Italy. Data obtained from all pre-operative ERCP analyses were recorded, including cholangiogram findings and performance of sphincterotomy. Statistical analysis was carried out using the IBM SPSS Statistic 19.0 software package. RESULTS: Between January 2010 and December 2016 575 patients (343 males, 242 females) underwent IOC during LC for symptomatic cholecystitis due to cholelithiasis. Among patients accrued for the study, 143 underwent preoperative ERCP for suspicion of common biliary duct stones. At the time of pre-operative ERCP, 123 were found to have common biliary duct stones while 20 (15%) presented negative ERCP. Complete removal of stones was accomplished in 119 patients. Among these patients, 13 had residual common biliary duct stones diagnosed by IOC (11%). Two patients underwent laparoscopic bile duct revision and, last, two patients were referred for ERCP at a later point. It is of note that all patients who presented residual stones by IOC had undergone pre-operative sphincterotomy. CONCLUSION: This study demonstrates that IOC is particularly effective in detecting residual stones in patients undergoing LC in sequential treatment of common biliary duct and/or gallbladder stones, and may be used on a routine basis in the sequential treatment of cholecystocholedocholithiasis.

RESUMEN

Skin tears represent a common condition of traumatic wounds, which may be encountered in some categories of individuals at the extremes of age, such as infants and the elderly. Despite the high prevalence and cost of these lesions, there has been little investigation into the risk factors that lead to this condition. The aim of this review was to systematically evaluate the main risk factors involved in development of skin tears. We planned to include all the studies dealing with risk factors related to skin tears. Only publications in English were considered. We excluded all the studies that did not properly fit our research question and those with insufficient data. Of the 166 records found, 24 matched our inclusion criteria. After reading the full-text articles, we decided to exclude seven articles because of the following reasons: (1) not responding properly to our research questions and (2) insufficient data; the final set included 17 articles. From a literature search, we found the following main issues related to risk factors, which have been described in detail in this section: age-related skin changes, dehydration, malnutrition, sensory changes, mobility impairment, pharmacological therapies and mechanical factors related to skin care practices. Our findings clearly show that in frail populations (especially infant and elderly), the stratification risk, as a primary prevention strategy, is an effective tool in avoiding the development of chronic wounds. The development and the implementation of prevention strategies based on appropriate knowledge of the risk factors involved and the adoption of correct techniques during skin care practices could reduce or even avoid the onset of skin tears.

RESUMEN

PURPOSE: Hemodynamics has a key role in atheropathogenesis. Indeed, atherosclerotic phenomena occur in vessels characterized by complex geometry and flow pattern, like the carotid bifurcation. Moreover, lifestyle is a significant risk factor. The aim of this study is to evaluate the hemodynamic effects due to two sedentary lifestyles - sitting and standing positions - in the carotid bifurcation in order to identify the worst condition and to investigate the atherosclerosis incidence. METHODS: The computational fluid dynamics (CFD) was chosen to carry out the analysis, in which in vivo non-invasive measurements were used as boundary conditions. Furthermore, to compare the two conditions, one patient-specific 3D model of a carotid bifurcation was reconstructed starting from computer tomography. Different mechanical indicators, correlated with atherosclerosis incidence, were calculated in addition to flow pattern and pressure distribution: the time average wall shear stress (TAWSS), the oscillatory shear index (OSI) and the relative residence time (RRT). RESULTS: The results showed that the bulb and the external carotid artery emergence are the most probable regions in which atherosclerotic events could happen. Indeed, low velocity and WSS values, high OSI and, as a consequence, areas with chaotic-swirling flow, with stasis (high RRT), occur. Moreover, the sitting position is the worst condition: considering a cardiac cycle, TAWSS is less than 17.2% and OSI and RRT are greater than 17.5% and 21.2%, respectively. CONCLUSIONS: This study suggests that if a person spends much time in the sitting position, a high risk of plaque formation and, consequently, of stenosis could happen.

RESUMEN

Epigenetic sciences study heritable changes in gene expression not related to changes in the genomic DNA sequence. The most important epigenetic mechanisms are DNA methylation, posttranslational histone modification, and gene regulation by noncoding RNAs, such as microRNAs (miRNAs) and long noncoding RNAs (lncRNAs). Cardiovascular diseases (CVD) are responsible for at least one-third of premature deaths worldwide and represent a heavy burden of healthcare expenditure. We will discuss in this review the most recent findings dealing with epigenetic alterations linked to cardiovascular physiopathology in patients. A particular focus will be put on the way these changes can be translated in the clinic, to develop innovative and groundbreaking biomarkers in CVD field.

RESUMEN

Objectives Functional chronic venous disease is an underestimated syndrome quite present in the general population. It affects up to 20% of the general population and is based on the presence of venous symptoms without instrumental evidence of anatomic and morphologic damage. The aim of this review article is to provide the reader with the most updated information on this phenomenon. Methods Medline and Scopus databases were searched without time limit using the key-word: 'Functional chronic venous disease of legs', C0s patients. We decided to include all the studies conducted about functional chronic venous disease. Randomised trials, cohort studies and reviews were contemplated in order to give a breadth of clinical data. Only publications in English were considered. We excluded all the studies with insufficient statistical analysis, possible biases and contradictions, not clear end-points, inconsistent or arbitrary conclusions. Results Of the 326 records found, after removal of 68 duplicates, 143 matched our inclusion criteria. After reading the full-text articles, 133 manuscripts were excluded. Ten full text articles were assessed for eligibility and four studies were excluded because of the following reasons: (a) no specific or important content and (b) insufficient data; the final set included six articles. Conclusions Functional chronic venous disease is a complex syndrome and further evidences are needed in order to assess the pathophysiology, the morbidity and the correct treatment of this venous dysfunction.

RESUMEN

Skin grafting is one of the most common surgical procedures in the area of non-healing wounds by which skin or a skin substitute is placed over a wound to replace and regenerate the damaged skin. Chronic leg ulcers are an important problem and a major source of expense for Western countries and for which many different forms of treatment have been used. Skin grafting is a method of treatment that decreases the area of chronic leg ulcers or heals them completely, thus improving a patient's quality of life. Skin grafting is an old technique, rediscovered during the first and second world wars as the main treatment for wound closure. Nowadays, skin grafting has a pivotal role in the context of modern wound healing and tissue regeneration. The aim of this review was to track and to analyse the specific outcomes this technique achieved, especially in the last decade, in relation to venous, arterial, diabetic, rheumatoid and traumatic leg ulcers. Our main findings indicate that autologous split-thickness skin grafting still remains the gold standard in terms of safety and efficacy for chronic leg ulcers; skin grafting procedures have greater success rates in chronic venous leg ulcers compared to other types of chronic leg ulcers; skin tissue engineering, also supported by genetic manipulation, is quickly expanding and, in the near future, may provide even better outcomes in the area of treatments for long-lasting chronic wounds.
