RESUMO

BACKGROUND: Soluble P-selectin (sP-selectin) has been proposed as a potential biomarker for venous thromboembolism (VTE) diagnosis with interesting results. However, its role in predicting early mortality in pulmonary embolism (PE) remains unexplored. METHODS: This observational, prospective, single-center study enrolled consecutive patients aged 18 or older with confirmed acute symptomatic PE and no prior anticoagulation. The study aims to assess the prognostic capacity of sP-selectin measured at the time of PE diagnosis for short-term mortality and major bleeding. RESULTS: A total of 196 patients, with a mean age of 69.1 years (SD 17), were included, of whom 52.6% were male. Within 30 days, 9.7% of patients (n = 19) died, and 5.1% (n = 10) suffered major bleeding. PE risk stratification revealed 4.6% (n = 9) with high-risk PE, 34.7% (n = 68) with intermediate-high-risk PE, 38.3% (n = 75) with intermediate-low-risk PE, and 22.5% (n = 44) with low-risk PE according to the European Society of Cardiology score. Mean plasma sP-selectin levels were comparable between survivors and non-survivors (489.7 ng/mL ±63 vs. 497.3 ng/mL ±51; p = .9). The ROC curve for 30-day all-cause mortality and major bleeding yielded an AUC of 0.49 (95% CI 0.36-0.63) and 0.46 (95% CI 0.24-0.68), respectively. Multivariate and survival analyses were precluded due to lack of significance. CONCLUSIONS: sP-selectin was not useful for predicting short-term mortality or major bleeding in patients with acute symptomatic pulmonary embolism. Further studies are required to clarify the role of sP-selectin in VTE, particularly in prognosticating PE outcomes.

RESUMO

BACKGROUND: This study aimed to validate the role of the D-dimer to lymphocyte ratio (DLR) for mortality prediction in a large national cohort of hospitalized coronavirus disease 2019 (COVID-19) patients. METHODS: A retrospective, multicenter, observational study that included hospitalized patients due to SARS-CoV-2 infection in Spain was conducted from March 2020 to March 2022. All biomarkers and laboratory indices analyzed were measured once at admission. RESULTS: A total of 10,575 COVID-19 patients were included in this study. The mean age of participants was 66.9 (±16) years, and 58.6% (6202 patients) of them were male. The overall mortality rate was 16.3% (n = 1726 patients). Intensive care unit admission was needed in 10.5% (n = 1106 patients), non-invasive mechanical ventilation was required in 8.8% (n = 923 patients), and orotracheal intubation was required in 7.5% (789 patients). DLR presented a c-statistic of 0.69 (95% CI, 0.68-0.71) for in-hospital mortality with an optimal cut-off above 1. Multivariate analysis showed an independent association for in-hospital mortality for DLR > 1 (adjusted OR 2.09, 95% CI 1.09-4.04; p = 0.03); in the same way, survival analysis showed a higher mortality risk for DLR > 1 (HR 2.24; 95% CI 2.03-2.47; p < 0.01). Further, no other laboratory indices showed an independent association for mortality in multivariate analysis. CONCLUSIONS: This study confirmed the usefulness of DLR as a prognostic biomarker for mortality associated with SARS-CoV-2 infection, being an accessible, cost-effective, and easy-to-use biomarker in daily clinical practice.

RESUMO

Vitamin D is an environmental factor related to multiple sclerosis that plays a significant role in immune regulation. TGF-ß is a superfamily of cytokines with an important dual effect on the immune system. TGF-ß inhibits the Th1 response while facilitating the preservation of regulatory T cells (FOXP3+) in an immunoregulatory capacity. However, when IL-6 is present, it stimulates the Th17 response. Our aim was to analyze the regulatory effect of vitamin D on the in vivo TGF-ß signaling pathway in patients with relapsing-remitting multiple sclerosis (RRMS). A total of 21 patients with vitamin D levels < 30 ng/mL were recruited and supplemented with oral vitamin D. All patients were receiving disease-modifying therapy, with the majority being on natalizumab. Expression of SMAD7, ERK1, ZMIZ1, BMP2, BMPRII, BMP4, and BMP5 was measured in CD4+ lymphocytes isolated from peripheral blood at baseline and one and six months after supplementation. SMAD7 was overexpressed at six months with respect to baseline and month one. ERK1 was overexpressed at six months with respect to month one of treatment. No significant differences in expression were observed for the remaining genes. No direct correlation was found with serum vitamin D levels. BMPRII expression changed differentially in non-natalizumab- versus natalizumab-treated patients. Changes were observed in the expression of ERK1, BMP2, and BMP5 based on disease activity measured using the Rio-Score, BMP2 in patients who had relapses, and BMP5 in those whose EDSS worsened. Our results suggest indirect regulation of vitamin D in TGF-ß pathway genes in patients with RRMS.

RESUMO

Atrial fibrillation (AF) is the most common arrhythmia in adults and diabetes mellitus (DM) is a major risk factor for cardiovascular diseases. However, the relationship between both pathologies has not been fully documented and new evidence supports the existence of direct and independent links. In the myocardium, a combination of structural, electrical, and autonomic remodeling may lead to AF. Importantly, patients with AF and DM showed more dramatic alterations than those with AF or DM alone, particularly in mitochondrial respiration and atrial remodeling, which alters conductivity, thrombogenesis, and contractile function. In AF and DM, elevations of cytosolic Ca2⁺ and accumulation of extra cellular matrix (ECM) proteins at the interstitium can promote delayed afterdepolarizations. The DM-associated low-grade inflammation and deposition/infiltration of epicardial adipose tissue (EAT) enforce abnormalities in Ca2+ handling and in excitation-contraction coupling, leading to atrial myopathy. This atrial enlargement and the reduction in passive emptying volume and fraction can be key for AF maintenance and re-entry. Moreover, the stored EAT can prolong action of potential durations and progression from paroxysmal to persistent AF. In this way, DM may increase the risk of thrombogenesis as a consequence of increased glycation and oxidation of fibrinogen and plasminogen, impairing plasmin conversion and resistance to fibrinolysis. Additionally, the DM-associated autonomic remodeling may also initiate AF and its re-entry. Finally, further evidence of DM influence on AF development and maintenance are based on the anti-arrhythmogenic effects of certain anti-diabetic drugs like SGLT2 inhibitors. Therefore, AF and DM may share molecular alterations related to Ca2+ mobility, mitochondrial function and ECM composition that induce atrial remodeling and defects in autonomic stimulation and conductivity. Likely, some specific therapies could work against the associated cardiac damage to AF and/or DM.

RESUMO

"Retractile mesenteritis" was the first name given to a rare, benign, inflammatory disease that affects the adipose tissue of the intestinal mesentery and less frequently other locations. Now labeled as mesenteric panniculitis, the pathogenic mechanism remains unclear. Several stimuli could be involved, and it is sometimes associated with other conditions such as malignancy or autoimmune diseases. We present a case of mesenteric panniculitis with extensive abdominal and extra-abdominal involvement that developed a few months after SARS-COV2 infection, raising the hypothesis of this virus as a potential trigger for autoinflammatory and autoimmune diseases.

RESUMO

BACKGROUND: The real predictive prognostic capacity of cellular indices (or ratios) is unclear in SARS-CoV-2 infection. This study aimed to assess the prognostic role of previously well-known laboratory indices and new ones in hospitalized COVID-19 patients. METHODS: A retrospective observational study from March to May 2022 evaluated laboratory indices on admission (neutrophil to lymphocyte-, derived neutrophil to lymphocyte-, platelet to lymphocyte-, CRP to lymphocyte-, CRP to albumin-, fibrinogen to lymphocyte-, d-dimer to lymphocyte-, ferritin to lymphocyte-, LDH to lymphocyte-, and IL-6 to lymphocyte ratios), in patients hospitalized due to SARS-CoV2 infection to determine the association with mortality, admission to an intensive care unit (ICU), need for non-invasive mechanical ventilation (NIMV), orotracheal intubation (OTI), or combined event at 30 days follow-up. RESULTS: A total of 1113 COVID-19 patients were evaluated with a mean age of 64.1 ± 15.9 years (58.49% male), 166 (14.91%) patients died, 58 (5.21%) required ICU admission, 73 (6.56%) needed NIMV, 46 (4.23%) needed OTI, and 247 (22.19%) presented the combined event. All the ratios evaluated in this study showed statistical significance in the univariate analysis for mortality and combined event; however, only d-dimer to lymphocyte ratio >0.6 presented an independent association in the multivariate analysis for 30-day mortality (adjusted OR 2.32; p = .047) and 30-day combined event (adjusted OR 2.62; p = .014). CONCLUSIONS: Laboratory indices might be a potential biomarker for better prognosis stratification in hospitalized COVID-19 patients. d-Dimer to lymphocyte ratio presents an independent association for 30-day mortality and 30-day adverse outcomes in hospitalized COVID-19 patients.

RESUMO

Statins, in addition to healthy lifestyle interventions, are the cornerstone of lipid-lowering therapy. Other low-density lipoprotein (LDL)-lowering drugs include ezetimibe, bile acid sequestrants, and PCSK9 inhibitors. As new evidence emerges from new clinical trials, therapeutic goals change, leading to renewed clinical guidelines. Nowadays, LDL goals are getting lower, leading to the "lower is better" paradigm in LDL-cholesterol (LDL-C) management. Several observational studies have shown that LDL-C control in real life is suboptimal in both primary and secondary preventions. It is critical to enhance the adherence to guideline recommendations through shared decision-making between clinicians and patients, with patient engagement in selecting interventions based on individual values, preferences, and associated conditions and comorbidities. This narrative review summarizes the evidence regarding the benefits of lipid-lowering drugs in reducing cardiovascular events, the pleiotropic effect of statins, real-world data on overtreatment and undertreatment of lipid-lowering therapies, and the changing LDL-C in targets in the clinical guidelines of dyslipidemias over the years.

RESUMO

Behçet syndrome (BS) is a unique type of vasculitis that affects veins and arteries of all sizes, leading to recurrent vascular events, mostly venous thrombosis. The prevalence of venous thromboembolism in BS patients ranges between 15 and 40%. Thrombosis is usually an early manifestation leading to diagnosis of BS in up to 40% of patients. BS is per se a model of inflammation-induced thrombosis. The primary autoimmune response activates lymphocytes that in turn produce a cytokine cascade that activates neutrophils, which modify the secondary structure of fibrinogen making it less susceptible to plasmin-induced lysis. This leads to endothelial dysfunction, platelet activation and overexpression of tissue factor leading to inflammatory thrombi, usually attached to the wall. The pathogenesis of thrombosis is especially relevant to direct the specific treatment, that is based on immunosuppression rather than anticoagulation. Superficial vein thrombosis (SVT) and deep vein thrombosis (DVT) are the most common form of thrombosis in BS, but thrombosis in atypical sites (cava vein, suprahepatic veins, intracardiac thrombus) and arterial involvement can also occur. We assessed the latest update of the European League Against Rheumatism recommendations for the management of BS. Vascular Behçet treatment is usually based of immunosuppressants, and the role of anticoagulation remains controversial. The use of interventional and surgical procedures should be carefully evaluated, due to the risk of triggering a vascular pathergy phenomenon.

RESUMO

The incidence and prevalence of heart failure (HF) is increasing worldwide, leading to high morbidity and mortality. The global management of HF involves lifestyle changes in addition to pharmacological treatments. Changes include exercise and dietary recommendations, mainly salt and fluid restriction, but without any clear evidence. We conducted a systematic review to analyse the degree of evidence for these dietary recommendations in HF. Only randomized controlled trials (RCT), and observational studies in humans were selected. Studies were considered eligible if they included participants with HF and sodium and/or fluid restriction. Publications in languages other than English or Spanish were excluded. We included 15 studies related to sodium or fluid restriction. Nine RCT and six observational studies showed some improvements in symptoms and quality of life and a degree of reduction in new hospitalizations, but the results are based on limited population groups, applying different methodologies, and with different restriction goals. We found a lack of clear evidence of the benefits of sodium/fluid restriction in chronic HF. The evidence is limited to few studies with conflicting results. Randomized clinical trials are needed to fill this gap in our knowledge.

RESUMO

Mid-regional pro-adrenomedullin (MR-proADM), methemoglobin (MetHb), and carboxyhemoglobin (COHb) levels have been associated with sepsis. In this study, we assessed the role of this potential biomarkers in critically ill COVID-19 patients. Outcomes were mortality and a combined event (mortality, venous or arterial thrombosis, and orotracheal intubation (OTI)) during a 30-day follow-up. A total of 95 consecutive patients were included, 51.6% required OTI, 12.6% patients died, 8.4% developed VTE, and 3.1% developed arterial thrombosis. MetHb and COHb levels were not associated with mortality nor combined event. Higher MR-proADM levels were found in patients with mortality (median of 1.21 [interquartile range-IQR-0.84;2.33] nmol/L vs. 0.76 [IQR 0.60;1.03] nmol/L, p = 0.011) and combined event (median of 0.91 [IQR 0.66;1.39] nmol/L vs. 0.70 [IQR 0.51;0.82] nmol/L, p < 0.001); the positive likelihood ratio (LR+) and negative likelihood ratio (LR-) for mortality were 2.40 and 0.46, respectively. The LR+ and LR- for combined event were 3.16 and 0.63, respectively. MR-proADM ≥1 nmol/L was the optimal cut-off for mortality and combined event prediction. The predictive capacity of MR-proADM showed an area under the ROC curve of 0.73 (95% CI, 0.62-0.81) and 0.72 (95% CI, 0.62-0.81) for mortality and combined event, respectively. In conclusion, elevated on-admission MR-proADM levels were associated with higher risk of 30-day mortality and 30-day poor outcomes in a cohort of critically ill patients with COVID-19.

RESUMO

BACKGROUND: Midregional-proadrenomedullin (MR-proADM) is a useful prognostic peptide in severe infectious pathologies in the adult population. However, there are no studies that analyze its utility in febrile urinary tract infection (fUTI) in children. An accurate biomarker would provide an early detection of patients with kidney damage, avoiding other invasive tests like renal scintigraphy scans. Our objective is to study the usefulness of MR-proADM as a biomarker of acute and chronic renal parenchymal damage in fUTI within the pediatric population. METHODS: A prospective cohort study was conducted in pediatric patients with fUTI between January 2015 and December 2018. Plasma and urine MR-proADM levels were measured at admission in addition to other laboratory parameters. After confirmation of fUTI, renal scintigraphy scans were performed during the acute and follow-up stages. A descriptive study has been carried out and sensitivity, specificity and ROC curves for MR-proADM, C-reactive protein, and procalcitonin were calculated. RESULTS: 62 pediatric patients (34 female) were enrolled. Scintigraphy showed acute pyelonephritis in 35 patients (56.5%). Of those patients, the median of plasmatic MR-proADM (P-MR-proADM) showed no differences compared to patients without pyelonephritis. 7 patients (11.3%) developed renal scars (RS). Their median P-MR-proADM levels were 1.07 nmol/L (IQR 0.66-1.59), while in patients without RS were 0.48 nmol/L (0.43-0.63) (p < 0.01). The AUC in this case was 0.92 (95% CI 0.77-0.99). We established an optimal cut-off point at 0.66 nmol/L with sensitivity 83.3% and specificity 81.8%. CONCLUSION: MR-ProADM has demonstrated a poor ability to diagnose pyelonephritis in pediatric patients with fUTI. However, P-MR-proADM proved to be a very reliable biomarker for RS prediction.

RESUMO

The relationship between inflammation and venous thrombosis is not well understood. An inflammatory response may be both the cause and consequence of venous thromboembolism (VTE). In fact, several risk factors of VTE modulate thrombosis through inflammatory markers. Acute pulmonary embolism (PE) is burdened by a remarkable mortality rate, up to 34% in severely ill patients presenting with hemodynamic instability. Initial mortality risk stratification is based on hemodynamic instability. Patients with a situation of hemodynamic stability require immediate further risk assessment based on clinical, imaging, and circulating biomarkers, as well as the presence of comorbidities. Some inflammatory biomarkers have shown potential usefulness in the risk stratification of patients with VTE, especially acute PE. C-reactive protein on admission is associated with 30-day mortality and bleeding in VTE patients. P-selectin is associated with right ventricle dysfunction in PE patients and might be associated with VTE recurrences and the extension of thrombosis. Tissue factor microparticles are associated with VTE recurrence in cancer-associated thrombosis. Other inflammatory biomarkers present scarce evidence (inflammatory cytokines, erythrocyte sedimentation rate, fibrinogen, leukocyte count). In this manuscript, we will review the prognostic role of different inflammatory biomarkers available both for clinical practice and research in VTE patients.

RESUMO

INTRODUCTION: COVID-19 predisposes patients to a higher risk of venous thromboembolism (VTE), although the extent of these implications is unclear and the risk of bleeding has been poorly evaluated. To date, no studies have reported long-term outcomes of patients with COVID-19 and VTE. METHOD: Prospective observational study to evaluate long-term (90 days or more) outcomes of patients diagnosed with VTE (PE, DVT of the extremities, or both) in the setting of COVID-19. The main outcome of the study was a compound of major bleeding and death. RESULTS: The study comprised 100 patients (mean age 65 ± 13.9 years). At the time of VTE diagnosis, 66% patients were hospitalized, 34.8% of them in the ICU. Mean follow-up was 97.9 ± 23.3 days. During the study period, 24% patients died and median time to death was 12 (IQR: 2.25-20.75) days, 11% patients had major bleeding and median time to event was 12 (IQR: 5-16) days. The cause of death was PE in 5% and bleeding in 2% of patients. There were no VTE recurrences. The main study outcome occurred in 29% patients. Risk of death or major bleeding was independently associated with ICU admission (HR 12.2; 95% CI 3.0-48.3), thrombocytopenia (HR 4.5; 95% CI 1.2-16.5), and cancer (HR 21.6; 95% CI 1.8-259). CONCLUSION: In patients with COVID-19 and VTE, mortality and major bleeding were high and almost a third of deaths were VTE-related. The majority of complications occurred in the first 30 days. ICU admission, thrombocytopenia, and cancer are risk factors for poor prognosis.

RESUMO

AIMS: The association of on-admission CRP and early adverse outcomes in acute venous thromboembolism (VTE) has not been investigated. We hypothesized that increased on-admission CRP levels would correlate with adverse outcomes in patients with acute VTE. METHOD: In this prospective observational study, consecutive patients with acute VTE were enrolled and CRP levels were measured within the first 24h after diagnosis. Mortality, bleeding and recurrence were recorded during a 30-day follow-up. RESULTS: 586 patients were included. Higher CRP levels were found in patients with mortality (7.5 vs 4.0mg/dL; p = 0.01) and bleeding (7.8 vs 3.9mg/dL; p = 0.03). Multivariable logistic regression showed that CRP levels >5mg/dL were associated with higher mortality (OR 6.25; 95% CI, 2.1-18.6) and bleeding (OR 2.7; CI 95% 1.3-5.7). These results were independent to ESC risk score and simplified PESI score for mortality prediction. The predictive capacity of CRP showed an area under the ROC curve - AUC - of .7 (CI 95% .56-.85) for mortality and .65 (CI 95% .54-.75) for bleeding. The prognostic capacity of the ESC risk score and simplified PESI score was improved after adding the CRP cutoff of 5mg/dL (AUC of .87 CI 95% .79-.95). CONCLUSION: Our findings suggest that on-admission CRP level may be a simple, widely available and valuable biomarker to identify high-risk VTE patients for early mortality and bleeding. CRP ≥5mg/dL was independently associated with 30-day VTE related death and bleeding


OBJETIVOS: La asociación de la medición de PCR al ingreso y las complicaciones precoces en la enfermedad tromboembólica venosa (ETV) aguda no ha sido evaluado. Nuestra hipótesis es que los niveles elevados de PCR al ingreso podrían estar correlacionados con complicaciones precoces en pacientes con ETV aguda. MÉTODOS: Estudio observacional prospectivo, en el que se incluyeron pacientes consecutivos con ETV aguda en los que se midió la PCR en las primeras 24h del diagnóstico. La mortalidad, el sangrado y la recurrencia fueron registrados durante el seguimiento a 30 días. RESULTADOS: Se incluyeron 586 pacientes. Se encontraron niveles más elevados de PCR en pacientes que fallecieron (7,5 vs. 4mg/dl; p = 0,01) y que sangraron (7,8 vs. 3,9mg/dl; p = 0,03). Una regresión logística multivariante mostró que niveles de PCR>5mg/dl se asociaron significativamente con mayor mortalidad (OR: 6,25; IC 95%: 2,1-18,6) y sangrado (OR: 2,7; IC 95%: 1,3-5,7). Estos resultados fueron independientes de las escalas pronósticas de mortalidad ESC y PESI simplificada. La capacidad predictiva de la PCR mostró un área bajo la curva (ABC) ROC de 0,7 (IC 95%: 0,56-0,85) para mortalidad y 0,65 (IC 95%: 0,54-0,75) para sangrado. La capacidad pronóstica de las escalas pronósticas ESC y PESI simplificada mejoró de forma significativa al añadir el punto de corte de PCR>5mg/dl (ABC de 0,87; IC 95%: 0,79-0,95). CONCLUSIÓN: La medición de PCR al ingreso puede ser un marcador sencillo y ampliamente disponible para identificar a pacientes con ETV aguda y alto riesgo de mortalidad y sangrado precoces. Niveles de PCR≥5mg/dl se asociaron de forma independiente con mayor mortalidad y sangrado a 30 días en pacientes con ETV aguda

RESUMO

Los inhibidores de la PCSK9, disponibles desde el año 2015, son capaces de reducir la concentración de colesterol transportado en las lipoproteínas de baja densidad entre un 40-70% y, por consiguiente, disminuir el riesgo cardiovascular. Presentamos un caso en el que un episodio cardiovascular grave apareció al espaciar la administración del tratamiento hipolipidemiante; discutiremos la importancia de mantener una concentración baja de colesterol, para conseguir un mayor beneficio clínico según los últimos estudios publicados


Inhibitors of the protein PCSK9, available since 2015, are capable of reducing the concentration of low density lipoprotein cholesterol by 40 to 70%, thus reducing the cardiovascular risk. The present case reports an adverse cardiovascular event that appeared when spacing out the administration of lipid-lowering treatment. A discussion will be presented on the importance of maintaining low cholesterol levels in order to achieve a greater benefit, according to the latest published clinical studies

RESUMO

Inhibitors of the protein PCSK9, available since 2015, are capable of reducing the concentration of low density lipoprotein cholesterol by 40 to 70%, thus reducing the cardiovascular risk. The present case reports an adverse cardiovascular event that appeared when spacing out the administration of lipid-lowering treatment. A discussion will be presented on the importance of maintaining low cholesterol levels in order to achieve a greater benefit, according to the latest published clinical studies.

RESUMO

AIMS: The association of on-admission CRP and early adverse outcomes in acute venous thromboembolism (VTE) has not been investigated. We hypothesized that increased on-admission CRP levels would correlate with adverse outcomes in patients with acute VTE. METHOD: In this prospective observational study, consecutive patients with acute VTE were enrolled and CRP levels were measured within the first 24h after diagnosis. Mortality, bleeding and recurrence were recorded during a 30-day follow-up. RESULTS: 586 patients were included. Higher CRP levels were found in patients with mortality (7.5 vs 4.0mg/dL; p=0.01) and bleeding (7.8 vs 3.9mg/dL; p=0.03). Multivariable logistic regression showed that CRP levels >5mg/dL were associated with higher mortality (OR 6.25; 95% CI, 2.1-18.6) and bleeding (OR 2.7; CI 95% 1.3-5.7). These results were independent to ESC risk score and simplified PESI score for mortality prediction. The predictive capacity of CRP showed an area under the ROC curve - AUC - of .7 (CI 95% .56-.85) for mortality and .65 (CI 95% .54-.75) for bleeding. The prognostic capacity of the ESC risk score and simplified PESI score was improved after adding the CRP cutoff of 5mg/dL (AUC of .87 CI 95% .79-.95). CONCLUSION: Our findings suggest that on-admission CRP level may be a simple, widely available and valuable biomarker to identify high-risk VTE patients for early mortality and bleeding. CRP ≥5mg/dL was independently associated with 30-day VTE related death and bleeding.

RESUMO

A growing interest has emerged in the beneficial effects of plant-based diets for the prevention of cardiovascular disease, diabetes and obesity. The Mediterranean diet, one of the most widely evaluated dietary patterns in scientific literature, includes in its nutrients two fluid foods: olive oil, as the main source of fats, and a low-to-moderate consumption of wine, mainly red, particularly during meals. Current mechanisms underlying the beneficial effects of the Mediterranean diet include a reduction in inflammatory and oxidative stress markers, improvement in lipid profile, insulin sensitivity and endothelial function, as well as antithrombotic properties. Most of these effects are attributable to bioactive ingredients including polyphenols, mono- and poly-unsaturated fatty acids. Polyphenols are a heterogeneous group of phytochemicals containing phenol rings. The principal classes of red wine polyphenols include flavonols (quercetin and myricetin), flavanols (catechin and epicatechin), anthocyanin and stilbenes (resveratrol). Olive oil has at least 30 phenolic compounds. Among them, the main are simple phenols (tyrosol and hydroxytyrosol), secoroids and lignans. The present narrative review focuses on phenols, part of red wine and virgin olive oil, discussing the evidence of their effects on lipids, blood pressure, atheromatous plaque and glucose metabolism.

RESUMO

Objective: Diabetes myonecrosis, also called diabetic muscle infarction (DMI), is a rare complication of diabetes. Given its rarity, our understanding of the underlying causes or the optimal management of DMI cases remains unclear. Methods: We report on a patient who experienced 2 episodes of DMI and we also review the literature. Results: A 46-year-old male with longstanding type 2 diabetes mellitus with multiple microvascular complications presented with acute-onset painful right thigh induration. On physical examination, he had right thigh swelling, tenderness, and crepitus. Blood tests showed leukocytosis, elevated creatine phosphokinase, and elevated acute-phase reactants. Microbiological cultures were negative. Glycated hemoglobin was 6.4% (46 mmol/mol). Magnetic resonance imaging demonstrated T2 hyperintensity involving the quadriceps group. The clinical and laboratory signs suggested a muscle infection. A muscle biopsy was suggestive of DMI. Eleven months later, the patient presented again with a 4-week history of left thigh pain and weakness in both legs. On examination, he had bilateral thigh anterior tenderness without evidence of swelling or induration. He also had marked bilateral proximal motor deficiency and inability to stand or ambulate. Despite a different clinical presentation, imaging features were consistent with DMI. The patient was managed with conservative therapy. His strength improved significantly after 3 months of follow up. Conclusion: The typical clinical presentation of DMI includes unilateral acute-onset pain in the quadriceps, local swelling, and the appearance of a palpable painful mass. The second episode in our patient illustrates an atypical clinical presentation of DMI and shows the importance of the correlation of clinical and imaging findings for the diagnosis of DMI.

RESUMO

The clinical profile, evolution and complications of treatment with rivaroxaban in a cohort of patients presenting with venous thromboembolism (VTE) were analyzed in an observational, non-interventional and prospective study.A total of 111 patients were included in the study. Clinical data were collected from the medical history of the patients and recorded in a specific database.Mean age was 63.8 ±â€Š17.4 years, 53.2% of patients were men, 55.9% had at least another concomitant condition, and 40.9% at least 1 VTE risk factor. 54.1% of patients presented with deep venous thrombosis, 32.4% with pulmonary embolism and 13.5% with both conditions simultaneously. The 61% of patients were admitted to hospital and mean hospital length-of-stay was 8.8 ±â€Š9.9 days. After a mean follow-up 530 ±â€Š464 days (median follow-up of 405 days), 3.9% of patients died and VTE recurrence occurred in 2.9% of patients. While receiving rivaroxaban, a first bleeding complication occurred in 8.1%; all events were minor bleeding.Our study supports the current literature data and confirms the similar results of real-life VTE patients with those enrolled in the rivaroxaban pivotal clinical trials. Rivaroxaban may facilitate outpatient treatment and might be considered as a first-line therapy for the management of VTE patients.
