Background Optimal duration of anticoagulation for cancer-associated thrombosis (CAT) remains unclear. This study assessed D-dimer (DD) and high-sensitivity C-reactive protein (hs-CRP) levels after the withdrawal of anticoagulation treatment to predict the risk of venous thromboembolism (VTE) recurrence among patients with CAT. Methods Prospective, multicentre study to evaluate CAT with ≥3 months of anticoagulation that was subsequently discontinued. Blood samples were taken when patients stopped the anticoagulation and 21 days later to determine the DD and hs-CRP levels. All patients were followed up for 6 months to detect VTE recurrence. Results Between 2013 and 2015, 325 patients were evaluated and 114 patients were ultimately enrolled in the study. The mean age was 62 ± 14 years and nearly 40% had metastasis. Ten patients developed VTE recurrence within 6 months (8.8%, 95% confidence interval [CI]: 4.3–15.5%). The DD and hs-CRP levels after 21 days were associated with VTE recurrence. The subdistribution hazard ratios were 9.82 for hs-CRP (95% CI: 19–52) and 5.81 for DD (95% CI: 1.1–31.7). Conclusions This study identified that hs-CRP and DD were potential biomarkers of VTE recurrence after discontinuation of anticoagulation in CAT. A risk-adapted strategy could identify low-risk patients who may benefit from discontinuation of anticoagulation.

It has been suggested that sleep-related breathing disorders (SRBD) involve a continuum that develops over the course of life. If modifiable factors could be identified, the progression of SRBD could perhaps be addressed early in life. Although some studies have looked at the evolution of SRBD in pre-pubertal children, very few studies obtained data in adolescents.Anthropometric, clinical and polygraphic variables were collected during a 4-yr follow-up study among 148 normal adolescents after initial cross-sectional analysis.From a total of 267 adolescents studied at baseline (mean¡SD age 14.3¡2.1 yrs), 148 (55.4%) were followed up for 4 yrs. During follow-up, there were no significant changes in snoring and polygraphic parameters. However, a tendency toward weight gain with centrally distributed fat was observed. Habitual snorers had a significantly higher body mass index and more centrally distributed fat than nonsnorers. Males had a higher snoring prevalence and a higher number of respiratory events than females. Snoring at baseline, male sex and poor academic performance were significant predictors of snoring at follow-up.Snoring tends to persist during adolescence and male sex acts as a risk factor. A relationship between snoring and academic performance was observed. These findings may have implications for long-term management of sleep-related breathing disorders.
