Using the Caprini Risk Score to Increase Awareness of Venous Thrombus Embolism in the Community: Know Your Score II. Clin Appl Thromb Hemost 2023; 29:10760296231188425. [PMID: 37487194 PMCID: PMC10369086 DOI: 10.1177/10760296231188425] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 06/13/2023] [Accepted: 06/24/2023] [Indexed: 07/26/2023] Open
Abstract
To assess individual participants' baseline thrombosis risk calculated by Caprini Risk Score (CRS) before injury, illness, or hospitalization occur, to increase the awareness of venous thromboembolism (VTE) by viewing 2 short videos. A cross-sectional study was conducted online between August 2022 and January 2023 in the USA, UK, and India to assess the risk of thrombosis of individuals as a baseline. One nursing practitioner and 4 high school students were on the research team. Descriptive statistical methods were used in data analysis. A total of 928 usable completed questionnaires from 945 participants were analyzed. The mean CRS was 4.93 ± 3.175; 0 to 4 (N = 460, 49.6%), 5 to 8 (N = 394, 42.5%), and 9 (N = 74: 8.0%). History of blood clots (N = 247, 26.6%), <40 years old (N = 133, 52.6%); women on oral contraceptives (N = 324, 34.9%), history of smoking (30%), diabetes (26%), and inflammatory bowel disease (IBD; 17.3%). Top-level findings: High incidence of family history of thrombosis (26.6%), smoking, diabetes, contraceptives, and IBD. The average CRS (7.9) in patients over 75 years indicates that even a minor surgical procedure may be associated with significant VTE risk. We achieved an important goal by increasing awareness of VTE using this unique method involving high school students and a nurse working with friends and families to complete the CRS assessment. Encouraging the respondents to share information with their personal physicians prior to the event and keep these data in their medical file is a potential valuable source of saving time. This study emphasizes the importance of individuals collecting baseline information prior to illness or hospitalization.

Abstract
SummaryFamilial clustering of venous thromboembolism (VTE) was described as far back as 1905 by Briggs. Although Egeberg discovered inherited deficiency of antithrombin in 1965, it was not until Dahlback discovered resistance to activated protein C in 1993 that it became clear that genetic factors are common risk factors of VTE. Several genes have been linked to familial aggregation of VTE and genome-wide association studies have found several novel gene loci. Still, it has been estimated that much of the heritability for VTE remains to be discovered. Family history (FH) of VTE is therefore still important to determine whether a patient has an increased genetic risk of VTE. FH has the potential to represent the sum of effects and interactions between environmental and genetic factors. In this article the design, methodology, results, clinical and genetic implications of FH studies of VTE are reviewed. FH in first-degree relatives (siblings and/or parents) is associated with a 2–3 times increased familial relative risk (FRR). However, the FRR is dependent on age, number of affected relatives, and presentation of VTE (provoked/unprovoked). Especially high familial risks are observed in individuals with two or more affected siblings (FFR> 50). However, the familial risk for recurrent VTE is much lower or non-significant. Moreover, FH of VTE appears mainly to be important for venous diseases (i. e. VTE and varicose veins). The familial associations with other diseases are weaker. In conclusion, FH of VTE is an important research tool and a clinically potential useful risk factor for VTE.

Abstract
The association between breast cancer and warfarin is inconclusive as most previous studies examined their association using patients with thromboembolism, whereas thromboembolism itself is a risk factor for cancer. We explored this issue using patients received mechanical heart valves replacement as a proxy for warfarin exposure as these patients need a lifelong warfarin treatment, and compared them with patients received bioprosthesis valves replacement (short-term warfarin treatment) in Sweden between 1987 and 2010. Patients who were operated on for valve replacement were identified from the Swedish Hospital Discharge Registry and linked to the Swedish Cancer Registry to examine the hazard ratios of subsequent breast cancer. A total of 12,242 women were operated on for valve replacement (5481 with mechanical valve and 6401 with bioprosthetic valve). For the entire cohort, the HR of breast cancer was 1.49 (95 % CI 1.09-2.02) among patients with mechanical valve replacement compared to those with bioprosthetic valve replacement. After controlling for a number of confounding factors using propensity score weighting, the HR was 1.69 (95 % CI 1.15-2.47). Our study found that patients with mechanical valve replacement have an increased risk of breast cancer compared to those with bioprosthetic valve replacement. If confirmed, this increased risk should be considered when recommending breast cancer screening for women with mechanical valve replacement. Long-term use of warfarin may explain the observed increase. If so, patients who have used warfarin long-term for other reasons should be studied for a possible increased risk of breast cancer.

Abstract
Background Varicose veins (VVs) have been associated with venous thromboembolism (VTE), but whether these diseases share familial susceptibility has not been determined. This nationwide study aimed to determine whether VTE shares familial susceptibility with VVs. Methods and Results Swedish Multigeneration Register data for persons aged 0 to 76 years during the period 1964–2008 were linked to the Swedish Inpatient and Outpatient Registers. Familial risks (standardized incidence ratios [SIRs]) of VTE and VVs were examined in 2 ways (ie, bidirectionally): risk of VTE in subjects whose siblings had been diagnosed with VVs and risk of VVs in persons whose siblings had been diagnosed with VTE. The analyses were repeated for spouses to determine the importance of shared adult family environment. In total, 96 810 siblings had VVs and 87 564 had VTE. An increased risk of VTE was observed in persons whose siblings had VVs (SIR 1.30, 95% CI 1.26 to 1.33), whereas persons whose siblings had VTE had an increased risk of VVs (SIR 1.30, 95% CI 1.27 to 1.34). If 2 or more siblings were affected by VTE, the risk for VVs was 1.70 (95% CI 1.53 to 1.88). Conversely, if 2 or more siblings were affected by VVs, the risk for VTE was 1.52 (95% CI 1.38 to 1.67). In spouses of VTE patients, a minor increased risk of VVs was observed (SIR 1.05 for husbands, SIR 1.06 for wives). The risk of VTE in spouses of VV patients was similarly small (SIR 1.01 for husbands, SIR 1.05 for wives). Conclusions VVs and VTE share familial susceptibility. This novel finding suggests the existence of shared familial and possibly genetic factors.
