Preliminary data and clinical experience have suggested an increased risk of abnormal uterine bleeding (AUB) in women of reproductive age treated with anticoagulants, but solid data are lacking. The TEAM-VTE study was an international multicenter prospective cohort study in women aged 18 to 50 years diagnosed with acute venous thromboembolism (VTE). Menstrual blood loss was measured by pictorial blood loss assessment charts at baseline for the last menstrual cycle before VTE diagnosis and prospectively for each cycle during 3 to 6 months of follow-up. AUB was defined as an increased score on the pictorial blood loss assessment chart (>100 or >150) or self-reported AUB. AUB-related quality of life (QoL) was assessed at baseline and the end of follow-up using the Menstrual Bleeding Questionnaire. The study was terminated early because of slow recruitment attributable to the COVID-19 pandemic. Of the 98 women, 65 (66%) met at least one of the 3 definitions of AUB during follow-up (95% confidence interval [CI], 57%-75%). AUB occurred in 60% of women (36 of 60) without AUB before VTE diagnosis (new-onset AUB; 95% CI, 47%-71%). Overall, QoL decreased over time, with a mean Menstrual Bleeding Questionnaire score increase of 5.1 points (95% CI, 2.2-7.9), but this decrease in QoL was observed only among women with new-onset AUB. To conclude, 2 of every 3 women who start anticoagulation for acute VTE experience AUB, with a considerable negative impact on QoL. These findings should be a call to action to increase awareness and provide evidence-based strategies to prevent and treat AUB in this setting. This was an academic study registered at www.clinicaltrials.gov as #NCT04748393; no funding was received.

The results of this study suggest that CTEPH is not a more common long-term complication after COVID-19-associated PE than after PE in non-COVID-19 patients, and thrombus resolution did not seem to be different from non-COVID-19-associated PE https://bit.ly/3IjvWL3

We investigated whether COVID-19 leads to persistent impaired pulmonary function, fibrotic-like abnormalities or psychological symptoms 12 months after discharge and whether severely ill patients (ICU admission) recover differently than moderately ill patients. This single-centre cohort study followed adult COVID-19 survivors for a period of one year after discharge. Patients underwent pulmonary function tests 6 weeks, 3 months and 12 months after discharge and were psychologically evaluated at 6 weeks and 12 months. Computed tomography (CT) was performed after 3 months and 12 months. 66 patients were analysed, their median age was 60.5 (IQR: 54–69) years, 46 (70%) patients were male. 38 (58%) patients had moderate disease and 28 (42%) patients had severe disease. Most patients had spirometric values within normal range after 12 months of follow-up. 12 (23%) patients still had an impaired lung diffusion after 12 months. Impaired pulmonary diffusion capacity was associated with residual CT abnormalities (OR 5.1,CI-95: 1.2–22.2), shortness of breath (OR 7.0, CI-95: 1.6–29.7) and with functional limitations (OR 5.8, CI-95: 1.4–23.8). Ground-glass opacities resolved in most patients during follow-up. Resorption of reticulation, bronchiectasis and curvilinear bands was rare and independent of disease severity. 81% of severely ill patients and 37% of moderately ill patients showed residual abnormalities after 12 months (OR 8.1, CI-95: 2.5–26.4). A minority of patients had symptoms of post-traumatic stress disorder, anxiety, depression and cognitive failure during follow-up. Some patients still had impaired lung diffusion 12 months after discharge and fibrotic-like residual abnormalities were notably prevalent, especially in severely ill patients.

A broad spectrum of long-term sequelae may be present in venous thromboembolism (VTE) survivors, affecting their quality of life and functioning. To monitor recovery and improve the prognosis of patients with persistent functional limitations, the development of a new outcome measure that could better capture the consequences of VTE was an unmet need. Starting as a call to action, the Post-VTE Functional Status (PVFS) scale was developed to meet this need. The PVFS scale is an easy-to-use clinical tool to measure and quantify functional outcomes after VTE by focusing on key aspects of daily life. As the scale was considered useful in coronavirus disease 2019 (COVID-19) patients as well, the Post-COVID-19 Functional Status (PCFS) scale was introduced early in the pandemic after slight adaptation. The scale has been well incorporated into both the VTE and COVID-19 research communities, contributing to the shift of focus toward patient-relevant functional outcomes. Psychometric properties have been evaluated, mainly for the PCFS scale but recently also for the PVFS scale, including validation studies of translations, showing adequate validity and reliability. In addition to serving as outcome measure in studies, guidelines and position papers recommend using the PVFS and PCFS scale in clinical practice. As broad use of the PVFS and PCFS scale in clinical practice is valuable to capture what matters most to patients, widespread implementation is a crucial next step. In this review, we discuss the development of the PVFS scale and introduction in VTE and COVID-19 care, the incorporation of the scale in research, and its application in clinical practice.

Based on the literature and users’ experiences, lessons could be learned after 2 years’ use of the Post-COVID-19 Functional Status (PCFS) scale, that could contribute to its optimal use. All in all, the PCFS scale provided added value during the pandemic. https://bit.ly/3KkI5Ak

Background The diagnosis of recurrent ipsilateral deep vein thrombosis (DVT) with compression ultrasonography (CUS) may be hindered by residual intravascular obstruction after previous DVT. A reference CUS, an additional ultrasound performed at anticoagulant discontinuation, may improve the diagnostic work-up of suspected recurrent ipsilateral DVT by providing baseline images for future comparison. Objectives To evaluate the cost-effectiveness of routinely performing reference CUS in DVT patients. Methods Patient-level data (n = 96) from a prospective management study (Theia study; NCT02262052) and claims data were used in a decision analytic model to compare 12 scenarios for diagnostic management of suspected recurrent ipsilateral DVT. Estimated health care costs and mortality due to misdiagnosis, recurrent venous thromboembolism, and bleeding during the first year of follow-up after presentation with suspected recurrence were compared. Results All six scenarios including reference CUS had higher estimated 1-year costs (€1,763–€1,913) than the six without reference CUS (€1,192–€1,474). Costs were higher because reference CUS results often remained unused, as 20% of patients (according to claims data) would return with suspected recurrent DVT. Estimated mortality was comparable in scenarios with (14.8–17.9 per 10,000 patients) and without reference CUS (14.0–18.5 per 10,000). None of the four potentially most desirable scenarios included reference CUS. Conclusion One-year health care costs of diagnostic strategies for suspected recurrent ipsilateral DVT including reference CUS are higher compared to strategies without reference CUS, without mortality benefit. These results can inform policy-makers regarding use of health care resources during follow-up after DVT. From a cost-effectiveness perspective, the findings do not support the routine application of reference CUS.
