Risk for post-thrombotic syndrome after lower-limb deep vein thrombosis: location of the thrombus or residual thrombi? / Risk razvitiia posttromboflebiticheskogo sindroma posle tromboza glubokikh ven nizhnikh konechnostei: lokalizatsiia tromba ili rezidual'nyi tromboz?

BACKGROUND: Many works aimed to determine factors that influence the onset of postthrombotic syndrome after an acute episode of deep venous thrombosis. We aimed to compare the prognostic value of the most proximal extent of thrombus (proximal and distal DVT) versus the residual thrombosis as identified by venous ultrasonography performed during follow-up. METHOD: We conducted a retrospective study of prospectively collected 1183 consecutive cohort patients in the RIETE registry after a first episode of deep venous thrombosis and assessed for postthrombotic syndrome after 12 months. RESULTS: Multivariate analysis revealed that: residual thrombosis (OR 1.40; 95% CI 0,88-2,21), the presence of cancer (OR 1.38; 95% CI: 0,64-2,97), immobility (OR 1.31; 95% CI 0,70-2,43) and estrogen-containing drugs use (OR 2.08, 95% CI 0,63-6,83), all had a predictive value for the occurrence of PTS. CONCLUSION: Our study results revealed that ultrasound finding of residual thrombosis is more predictive than proximal location of thrombus for postthrombotic syndrome after episode of deep venous thrombosis. Real life data from a large group of patients from the RIETE registry substantiates that.

D-dimer levels and risk of recurrence following provoked venous thromboembolism: findings from the RIETE registry.

BACKGROUND: Patients with venous thromboembolism (VTE) secondary to transient risk factors may develop VTE recurrences after discontinuing anticoagulation. Identifying at-risk patients could help to guide the duration of therapy. METHODS: We used the RIETE database to assess the prognostic value of d-dimer testing after discontinuing anticoagulation to identify patients at increased risk for recurrences. Transient risk factors were classified as major (postoperative) or minor (pregnancy, oestrogen use, immobilization or recent travel). RESULTS: In December 2018, 1655 VTE patients with transient risk factors (major 460, minor 1195) underwent d-dimer measurements after discontinuing anticoagulation. Amongst patients with major risk factors, the recurrence rate was 5.74 (95% CI: 3.19-9.57) events per 100 patient-years in those with raised d-dimer levels and 2.68 (95% CI: 1.45-4.56) in those with normal levels. Amongst patients with minor risk factors, the rates were 7.79 (95% CI: 5.71-10.4) and 3.34 (95% CI: 2.39-4.53), respectively. Patients with major risk factors and raised d-dimer levels (n = 171) had a nonsignificantly higher rate of recurrences (hazard ratio [HR]: 2.14; 95% CI: 0.96-4.79) than those with normal levels. Patients with minor risk factors and raised d-dimer levels (n = 382) had a higher rate of recurrences (HR: 2.34; 95% CI: 1.51-3.63) than those with normal levels. On multivariate analysis, raised d-dimers (HR: 1.74; 95% CI: 1.09-2.77) were associated with an increased risk for recurrences in patients with minor risk factors, not in those with major risk factors. CONCLUSIONS: Patients with raised d-dimer levels after discontinuing anticoagulant therapy for VTE provoked by a minor transient risk factor were at an increased risk for recurrences.

Pilot evaluation of home delivery programme in haemophilia.

WHAT IS KNOWN AND OBJECTIVES: Most of the clotting factor (CF) dispensations to haemophiliac patients are centralized in a few haemophilia treatment centres, necessitating frequent visits and long travel distances. The aim was to evaluate the home delivery programme developed by the Outpatient Pharmaceutical Care Unit (OPCU) through the association of patients (ASHECOVA). METHODS: A specific software programme was designed to communicate the individual CF requirements. Dispensations were prepared in advance, and an ASHECOVA member collected and delivered to patients' homes in optimal conditions. Data regarding the programme were analysed from December 2011 to December 2017. An electronic satisfaction survey with 34 questions was conducted, asking about organizational aspects, education and communication, use of apps and satisfaction level. RESULTS AND DISCUSSION: Forty-nine patients were included and 2464 home deliveries were made, without any reported incident related to dispensation errors, drug preservation, communication or confidentiality problems. This system avoids 11.4 annual dispensation visits per patient to OCPU, and a mean travel distance, time and cost of 1189.1 km, 945.3 minutes and 373.5 euros, respectively. Overall satisfaction with home delivery was 9.7, without any change suggested in the current system. Ninety-five per cent of individuals believed that the programme improves adherence and all patients would recommend it to other patients. The most common benefits reported were less frequent visits to hospital, reducing time and cost spent on transportation. WHAT IS NEW AND CONCLUSION: The home delivery programme guarantees a proper follow-up of treatments with full patient satisfaction. This programme allows OPCU to achieve better pharmaceutical care, traceability of the process and optimization of working times and CF stock management.

Evaluation of the antimutagenic activity and mode of action of the fructooligosaccharide inulin in the meristematic cells of Allium cepa culture.

This study evaluated the mutagenicity and antimutagenicity of inulin in a chromosomal aberration assay in cultures of the meristematic cells of Allium cepa. The treatments evaluated were as follows: negative control--seed germination in distilled water; positive control--aqueous solution of methyl methanesulfonate (10 µg/mL MMS); mutagenicity--aqueous solutions of inulin (0.015, 0.15, and 1.50 µg/mL); and antimutagenicity--associations between MMS and the different inulin concentrations. The antimutagenicity protocols established were pre-treatment, simultaneous simple, simultaneous with pre-incubation, and post-treatment. The damage reduction percentage (DR%) was 43.56, 27.77, and 55.92% for the pre-treatment; -31.11, 18.51, and 7.03% for the simultaneous simple; 30.43, 19.12, and 21.11% for the simultaneous with pre-incubation; and 64.07, 42.96, and 53.70% for the post-treatment. The results indicated that the most effective treatment for inhibiting damages caused by MMS was the post-treatment, which was followed by the pre-treatment, suggesting activity by bioantimutagenesis and desmutagenesis. The Allium cepa assay was demonstrated to be a good screening test for this type of activity because it is easy to perform, has a low cost, and shows DR% that is comparable to that reported studies that evaluated the prevention of DNA damage in mammals by inulin.

Evaluation of the antimutagenic and anticarcinogenic effects of inulin in vivo.

The incidence of colorectal cancer is growing worldwide. The characterization of compounds present in the human diet that can prevent the occurrence of colorectal tumors is vital. The oligosaccharide inulin is such a compound. The aim of this study was to evaluate the antigenotoxic, antimutagenic and anticarcinogenic effects of inulin in vivo. Our study is based on 3 assays that are widely used to evaluate chemoprevention (comet assay, micronucleus assay, and aberrant crypt focus assay) and tests 4 protocols of treatment with inulin (pre-treatment, simultaneous, post-treatment, and pre + continuous). Experiments were carried out in Swiss male mice of reproductive age. In order to induce DNA damage, we used the pro-carcinogenic agent 1,2-dimethylhydrazine. Inulin was administered orally at a concentration of 50 mg/kg body weight following the protocols mentioned above. Inulin was not administered to the control groups. Our data from the micronucleus assay reveal antimutagenic effects of inulin in all protocols. The percentage of inulin-induced damage reduction ranged from 47.25 to 141.75% across protocols. These data suggest that inulin could act through desmutagenic and bio-antimutagenic mechanisms. The anticarcinogenic activity (aberrant crypt focus assay) of inulin was observed in all protocols and the percentages of damage reduction ranged from 55.78 to 87.56% across protocols. Further tests, including human trials, will be necessary before this functional food can be proven to be effective in the prevention and treatment of colon cancer.

Pre-treatment with glutamine reduces genetic damage due to cancer treatment with cisplatin.

Cisplatin is an effective antineoplastic drug. However, it provokes considerable collateral effects, including genotoxic and clastogenic activity. It has been reported that a diet rich in glutamine can help inhibit such collateral effects. We evaluated this activity in 40 Swiss mice, distributed into eight experimental groups: G1 - Control group (PBS 0.1 mL/10 g body weight); G2 - cisplatin group (cisplatin 6 mg/kg intraperitoneally); G3, G4, G5 - glutamine groups (glutamine at 150, 300, and 600 mg/kg, respectively; orally); G6, G7, G8 - Pre-treatment groups (glutamine at 150, 300, and 600 mg/kg, respectively; orally and cisplatin 6 mg/kg intraperitonially). For the micronucleus assay, samples of blood were collected (before the first use of the drugs at T0, then 24 (T1) and 48 (T2) hours after the first administration). For the comet assay, blood samples were collected only at T2. The damage reduction percentages for the micronucleus assay were 90.0, 47.3, and 37.3% at T1 and 46.0, 38.6, and 34.7% at T2, for G6, G7, and G8 groups, respectively. For the comet assay, the damage reduction percentages were 113.0, 117.4, and 115.0% for G6, G7, and G8, respectively. We conclude that glutamine is able to prevent genotoxic and clastogenic damages caused by cisplatin.

[Ventricular assist device as alternative to heart transplant in a hospitalized patient in an intensive care unit: clinical case]. / Asistencia ventricular definitiva como alternativa al trasplante cardíaco en un paciente ingresado en una unidad de cuidados intensivos: un caso clínico.

OBJECTIVE: To present and analyze a clinical case that addresses the care plan for a patient with permanent ventricular assist in an intensive care unit (ICU). CLINICAL CASE PRESENTATION: A 65-year-old man admitted to an ICU in a tertiary teaching hospital in September 2011 after receiving an implant of a permanent ventricular assist device (Heartmate II). DISCUSSION AND IMPLICATIONS FOR PRACTICE: The case analysis has been structured into 3 categories identified in the review of the literature: prevention of risks and complications, management of the device and health education. CONCLUSION: This study shows the importance of establishing a protocolized care plan for the patients who are carriers of permanent ventricular assist in the ICU. This would avoid postoperative complications, reduce costs and hospitalization time.

Ethoxysclerol injection into the posterior ligament under single puncture arthroscopy for the treatment of recurrent temporomandibular joint dislocation: a novel technique.

The pathogenesis of recurrent chronic dislocation of the temporomandibular joint has been attributed to multiple factors, such as hyperlaxity of the soft tissues or alterations in the size of the temporal eminence. When there are no bone alterations, the injection of sclerosing solutions is an effective treatment that can be performed using a blind technique or with arthroscopy. This study presents an innovative technique for injecting ethoxysclerol into the posterior ligament through single puncture arthroscopy. This approach offers a safe and effective alternative for surgeons without experience in high-complexity arthroscopy who want to ensure precise injection of the agent into the desired anatomical areas.

Clinical presentation and outcome of venous thromboembolism in COPD.

Chronic obstructive pulmonary disease (COPD) is a moderate risk factor for venous thromboembolism (VTE), but neither the clinical presentation nor the outcome of VTE in COPD patients is well known. The clinical presentation of VTE, namely pulmonary embolism (PE) or deep venous thrombosis (DVT), and the outcome at 3 months (death, recurrent VTE or bleeding) were compared between 2,984 COPD patients and 25,936 non-COPD patients included in the RIETE (Registro Informatizado de la Enfermedad TromboEmbólica) registry. This ongoing international, multi-centre registry includes patients with proven symptomatic PE or DVT. PE was the more frequent VTE presentation in COPD patients (n = 1,761, 59%). PE presentation was more significantly associated with COPD patients than non-COPD patients (OR 1.64, 95% CI 1.49-1.80). During the 3-month follow-up, mortality (10.8% versus 7.6%), minor bleeding (4.5% versus 2.3%) or first VTE recurrences as PE (1.5% versus 1.1%) were significantly higher in COPD patients than in non-COPD patients. PE was the most common cause of death. COPD patients presented more frequently with PE than DVT. It may explain the worse prognosis of COPD patients, with a higher risk of death, bleeding or VTE recurrences as PE compared with non-COPD patients. Further therapeutic options are needed.

Meta-analyses of sulodexide and other drugs in prevention and treatment of post-thrombotic syndrome.

OBJECTIVE: Post-thrombotic syndrome (PTS) is a common chronic complication of deep vein thrombosis. Elastic compression (ECS) is the common pillar for PTS prevention and treatment, while the pharmacological approach for PTS includes direct oral anticoagulants (DOACs) and venoactive drugs (VADs) for prevention and treatment, respectively. Sulodexide can be used both in long-term prevention and in the treatment of PTS. To better understand the efficacy of the main drugs used in the prevention (sulodexide or DOACs) and treatment of PTS (sulodexide or VADs), pairwise meta-analyses of observational studies and RCTs were conducted. MATERIALS AND METHODS: A literature search in MEDLINE, Embase, and Cochrane Library for observational studies and RCTs was performed. Incidence of PTS, reduction in PTS signs or symptoms and proportion of patients with complete venous ulcers healing were the primary outcomes for prevention and treatment of PTS, respectively. Fixed and Random effect model meta-analyses were performed. Heterogeneity and publication bias were assessed. R® software was used for the analysis. RESULTS: 893 articles were identified during the search. 8 observational studies (6 for DOACs and 2 for sulodexide) and 2 RCTs for sulodexide, out of the 11 studies included in the qualitative synthesis, were included for the prevention and treatment of PTS, respectively. Meta-analyses of observational studies showed an overall incidence of PTS of 15% (95% CI, 11-19) for sulodexide, and a 50% reduction of PTS signs and/or symptoms for rivaroxaban compared to warfarin (OR, 0.50; 95% CI, 0.38-0.65). The overall estimate of the two sulodexide RCTs showed a significant improvement in complete ulcer healing, with an OR of 2.32 (95% CI, 1.49-3.63). CONCLUSIONS: In prevention of PTS, sulodexide and rivaroxaban showed a low incidence and reduced risk of PTS respectively, while in PTS treatment, sulodexide was significantly effective in the complete ulcers healing. These results confirm the need to move from the traditional single-pillar approach with elastic compression stockings to a more effective multi-pillar approach, tailoring the treatment to each individual patient.

Glucose control and outcome in patients with stable diabetes and previous coronary, cerebrovascular or peripheral artery disease. Findings from the FRENA Registry.

AIM: The aim of this study was to address the controversy over the influence of intensive glucose control on the risk for cardiovascular events in patients with Type 2 diabetes. METHODS: FRENA is an ongoing registry of stable outpatients with symptomatic coronary artery disease, cerebrovascular disease or peripheral artery disease. We compared the incidence of subsequent ischaemic events (myocardial infarction, stroke or critical limb ischaemia) in patients with Type 2 diabetes and mean HbA(1c) levels < 7.0% (< 53 mmol/mol) vs. those with HbA(1c) levels > 7.0% (> 53 mmol/mol). RESULTS: Of 974 patients with Type 2 diabetes, 480 (49%) had mean HbA(1c) levels < 7% (< 53 mmol/mol). Over a mean follow-up of 14 months, 126 patients (13%) had subsequent ischaemic events: myocardial infarction (43), stroke (29) and critical limb ischaemia (64). The incidence of subsequent ischaemic events was significantly lower in patients with mean HbA(1c) levels < 7.0% (< 53 mmol/mol) than in those with HbA(1c) levels > 7.0% (> 53 mmol/mol) (8.6 vs. 14 per 100 patient-years; rate ratio 0.6; 95% CI 0.4-0.9). These differences persisted after adjusting for potential confounders. However, this better outcome was only found in patients presenting with coronary artery disease (rate ratio 0.4; 95% CI 0.2-0.8), not in those with cerebrovascular disease (rate ratio 0.9; 95% CI 0.4-2.0) or peripheral artery disease (rate ratio 0.8; 95% CI 0.5-1.3). Patients with mean HbA(1c) levels < 7.0% (< 53 mmol/mol) also had a lower mortality (rate ratio 0.6; 95% CI 0.3-0.99). CONCLUSIONS: In secondary prevention, patients with diabetes and HbA(1c) levels < 7.0% (< 53 mmol/mol) had a lower incidence of subsequent ischaemic events and a lower mortality than those with HbA(1c) levels > 7.0% (> 53 mmol/mol). These differences appeared only in patients with coronary artery disease.

Outcomes in patients with acute pulmonary embolism and patent foramen ovale: Findings from the RIETE registry.

INTRODUCTION: An increased risk of ischemic stroke in patients with acute pulmonary embolism (PE) and patent foramen ovale (PFO) was reported but few data exist regarding prognostic outcomes of those patients. MATERIAL AND METHODS: Using data in the RIETE registry, we compared the characteristics, therapeutic approaches and outcomes of patients with PE according to the presence or absence of PFO. RESULTS: From August 2016 to January 2020, 4148 patients with acute PE were enrolled. Of these, 2775 (67%) had no transthoracic echocardiogram (TTE), 993 (24%) underwent TTE but had no reported results on PFO. Among the remaining 380 patients, 287 (74%) did not have PFO and 93 (26%) had PFO. Patients with PFO were more likely to have chronic heart failure, prior myocardial infarction or ischemic stroke than those without PFO. Patients with PFO had a higher rate of subsequent ischemic stroke than those without PFO (hazard ratio (HR): 9.28; 95% CI: 1.83-69.1), than those with TTE but no data on PFO (HR: 10.1; 95% CI: 2.56-42.4) or without TTE (HR: 9.78; 95% CI: 3.02-28.4). On multivariable analysis, patients with PFO were at increased risk for subsequent ischemic stroke than those without PFO (HR: 8.96; 95% CI: 1.68-47.7). CONCLUSIONS: PFO was searched in a minority of patients with an acute PE in real life setting. Subject to possible selection and measurement biases, our results confirmed a higher risk of ischemic stroke in PE patients with PFO compared to those without PFO. This association warrants further investigation before determining the best therapeutic option in patients with acute PE and concomitant PFO.

Summary of recommendations and key points of the consensus of Spanish scientific societies (SEPAR, SEMICYUC, SEMES; SECIP, SENEO, SEDAR, SENP) on the use of non-invasive ventilation and high-flow oxygen therapy with nasal cannulas in adult, pediatric, and neonatal patients with severe acute respiratory failure. / Sumario de las recomendaciones y puntos clave del Consenso de las Sociedades Científicas Españolas (SEPAR, SEMICYUC, SEMES; SECIP, SENeo, SEDAR, SENP) para la utilización de la ventilación no invasiva y terapia de alto flujo con cánulas nasales en el paciente adulto, pediátrico y neonatal con insuficiencia respiratoria aguda grave.

Non-invasive respiratory support (NIRS) in adult, pediatric, and neonatal patients with acute respiratory failure (ARF) comprises two treatment modalities, non-invasive mechanical ventilation (NIMV) and high-flow nasal cannula (HFNC) therapy. However, experts from different specialties disagree on the benefit of these techniques in different clinical settings. The objective of this consensus was to develop a series of good clinical practice recommendations for the application of non-invasive support in patients with ARF, endorsed by all scientific societies involved in the management of adult and pediatric/neonatal patients with ARF. To this end, the different societies involved were contacted, and they in turn appointed a group of 26 professionals with sufficient experience in the use of these techniques. Three face-to-face meetings were held to agree on recommendations (up to a total of 71) based on a literature review and the latest evidence associated with 3 categories: indications, monitoring and follow-up of NIRS. Finally, the experts from each scientific society involved voted telematically on each of the recommendations. To classify the degree of agreement, an analogue classification system was chosen that was easy and intuitive to use and that clearly stated whether the each NIRS intervention should be applied, could be applied, or should not be applied.

Clinical Consensus Recommendations Regarding Non-Invasive Respiratory Support in the Adult Patient with Acute Respiratory Failure Secondary to SARS-CoV-2 infection. / Recomendaciones de consenso respecto al soporte respiratorio no invasivo en el paciente adulto con insuficiencia respiratoria aguda secundaria a infección por SARS-CoV-2.

Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus, that was first recognized in Wuhan, China, in December 2019. Currently, the World Health Organization (WHO) has defined the infection as a global pandemic and there is a health and social emergency for the management of this new infection. While most people with COVID-19 develop only mild or uncomplicated illness, approximately 14% develop severe disease that requires hospitalization and oxygen support, and 5% require admission to an intensive care unit. In severe cases, COVID-19 can be complicated by the acute respiratory distress syndrome (ARDS), sepsis and septic shock, and multiorgan failure. This consensus document has been prepared on evidence-informed guidelines developed by a multidisciplinary panel of health care providers from four Spanish scientific societies (Spanish Society of Intensive Care Medicine [SEMICYUC], Spanish Society of Pulmonologists [SEPAR], Spanish Society of Emergency [SEMES], Spanish Society of Anesthesiology, Reanimation, and Pain [SEDAR]) with experience in the clinical management of patients with COVID-19 and other viral infections, including SARS, as well as sepsis and ARDS. The document provides clinical recommendations for the noninvasive respiratory support (noninvasive ventilation, high flow oxygen therapy with nasal cannula) in any patient with suspected or confirmed presentation of COVID-19 with acute respiratory failure. This consensus guidance should serve as a foundation for optimized supportive care to ensure the best possible chance for survival and to allow for reliable comparison of investigational therapeutic interventions as part of randomized controlled trials.
