Catheter-related atrial thrombosis in a patient with recent cerebral haemorrhage: to treat or not to treat?
No full textCancer prevention and vitamin K antagonists: An overview
No full textThe relation of cancer to thromboembolism has been described since the mid 1800s. Different studies in animal and in vitro models have confirmed the link between the haemostatic system and both tumor stroma formation and metastasis. Although the mechanisms of warfarin effects on cancer are not elucidated, but are based on hypothesis, various studies have reported interesting results in this setting. But does warfarin added to recommended anti-tumour therapy improve survival of cancer patients? For the time being it is difficult to answer this question. Data from the literature are few and sometimes contradictory. Trials are characterized by important differences in studied cohorts, histological types of cancers evaluated, and in the treatment protocols. Most studies show that there is benefit from the addition of warfarin to chemotherapy in the tumour development, expansion and on the patient survival, especially in particular types of cancers. These data, although fascinating, do not rationalize the use of anticoagulation in the routine prophylaxis of cancer, however, they call for efforts in preparing large scale randomized trials to elucidate the effect of anticoagulation in the setting of neoplastic disease
Antiplatelets treatment in atherosclerotic renal artery stenosis: need of consensus-based recommendations.
No full textNoSAS score associated with arterial stiffness in a large cohort of healthy individuals.
No full textWe read with interest Helena Marti-Soler and colleagues' Article1 in the Lancet Respiratory Medicine on their proposed clinical algorithm (NoSAS), which showed good sensitivity for detecting individuals at risk of sleep-disordered breathing with greater accuracy than other validated questionnaires. This algorithm could be potentially useful for screening purposes in large cohorts for whom polysomnography is too expensive and time consuming

No full textLong-term use of vitamin K antagonists and incidence of cancer: a population-based study
No full textWhether long-term use of vitamin K antagonists (VKAs) might affect the incidence of cancer is a longstanding hypothesis. We conducted a population-based study including all cancer- and thromboembolism-free patients of our health area; study groups were defined according to chronic anticoagulant use to VKA-exposed and control groups. Cancer incidence and cancer-related and overall mortality was assessed in both groups. 76 008 patients (3231 VKA-exposed and 72 777 control subjects) were followed-up for 8.2 (± 3.2) years. After adjusting for age, sex, and time-to-event, the hazard ratio of newly diagnosed cancer in the exposed group was 0.88 (95% confidence interval [95% CI] 0.80-0.98; P < .015). VKA-exposed patients were less likely to develop prostate cancer, 0.69 (95% CI 0.50-0.97; P = .008). The adjusted hazard ratio for cancer-related and overall mortality was 1.07 (95% CI 0.92-1.24) and 1.12 (95% CI 1.05-1.19), respectively. These results support the hypothesis that anticoagulation might have a protective effect on cancer development, especially prostate cancer
Treatment options in fibromuscular dysplasia of the renal artery: when percutaneous transluminal angioplasty is at high risk?
No full textTreatment of atherosclerotic renovascular hypertension: review of observational studies and a meta-analysis of randomized clinical trials.
Full text linkAtherosclerotic renal artery stenosis can cause ischaemic nephropathy and arterial hypertension. We herein review the observational and randomized clinical trials (RCTs) comparing medical and endovascular treatment for control of hypertension and renal function preservation. Using the Population Intervention Comparison Outcome (PICO) strategy, we identified the relevant studies and performed a novel meta-analysis of all RCTs to determine the efficacy and safety of endovascular treatment when compared with medical therapy. The following outcomes were examined: baseline follow-up difference in mean systolic and diastolic blood pressure (BP), serum creatinine, number of drugs at follow-up, incident events (heart failure, stroke, and worsening renal function), mortality, cumulative relative risk of heart failure, stroke, and worsening renal function. Seven studies comprising a total of 2155 patients (1741 available at follow-up) were considered, including the recently reported CORAL Study. Compared with baseline, diastolic BP fell more at follow-up in patients in the endovascular than in the medical treatment arm (standard difference in means -0.21, 95% confidence interval (CI): -0.342 to -0.078, P = 0.002) despite a greater reduction in the mean number of antihypertensive drugs (standard difference in means -0.201, 95% CI: -0.302 to -0.1, P < 0.001). At variance, follow-up changes (from baseline) of systolic BP, serum creatinine, and incident cardiovascular event rates did not differ between treatment arms. Thus, patients with atherosclerotic renal artery stenosis receiving endovascular treatment required less anti-antihypertensive drugs at follow-up than those medically treated. Notwithstanding this, they evidenced a better control of diastolic BP
