Abstract
BACKGROUND More than 150 million women worldwide use oral contraceptives. Women with inherited thrombophilia and carriers of certain thrombophilia gene variants, such as factor V Leiden and the prothrombin, are at an increased risk for venous thromboembolism, especially when combined with oral contraceptive use. Venous thromboembolism is a complex disorder involving many genetic risk factors, and recently, polygenic risk scores have been proposed to capture a significant proportion of the genetic risk of venous thromboembolism. OBJECTIVE The aim of this study was to estimate the risk for developing venous thromboembolism when initiating oral contraceptive use (first 2 years) and during continued use among women with a high genetic liability. STUDY DESIGN We used a prospective study design in which 244,420 participants from the UK Biobank were followed from birth. The effect of oral contraceptive use during the first 2 years and in the remaining years of oral contraceptive use on the risk of developing venous thromboembolism was estimated using a Cox regression with a time-dependent exposure variable. Women were stratified according to their polygenic risk scores and whether they were carriers of factor V Leiden and/or prothrombin variants. RESULTS When genetic risk was not considered, an increased risk for venous thromboembolism was observed during the first 2 years of oral contraceptive use (hazard ratio, 3.09; 95% confidence interval, 3.00-3.20) but not during continued use (hazard ratio, 0.92; 95% confidence interval, 0.80-1.05). However, when genetic risk was considered, women in the highest polygenic risk score category had a more pronounced risk of developing a venous thromboembolism during the first 2 years of oral contraceptive use (hazard ratio, 6.35; 95% confidence interval, 4.98-8.09), and a high risk was also observed among factor V Leiden (hazard ratio, 5.73; 95% confidence interval, 5.31-6.17) and prothrombin variant carriers (hazard ratio, 5.23; 95% confidence interval, 4.67 - 5.87). A high polygenic risk score in combination with being a factor V Leiden and prothrombin variant carrier conferred the highest risk for developing a venous thromboembolism during the first 2 years of oral contraceptive use (hazard ratio, 14.8; 95% confidence interval, 9.28-23.6). Women with a high genetic liability also had an increased risk during continued use but it was less pronounced, and the highest risk was conferred to carriers of both factor V Leiden and the prothrombin variant (hazard ratio, 4.93; 95% confidence interval, 3.16-7.7). CONCLUSION Evaluating polygenic risk can identify additional venous thromboembolism risk that is not captured in the commonly investigated genes for inherited thrombophilia. Our results indicate that oral contraceptive use is associated with an increased risk for developing a venous thromboembolism, particularly among women with a high genetic predisposition, and that oral contraceptive use dramatically increases the risk thereof short after initiation of use, which decreases with continued use. This suggests that the polygenic risk score could be used to identify women who are at high risk for developing a venous thromboembolism and advise them on alternative methods of contraception.

Abstract
PURPOSE The purpose of this study was to investigate the risk factors for umbilical artery thrombosis (UAT) and the relationship between umbilical artery thrombosis and perinatal outcomes. METHODS This was a retrospective study that enrolled singleton pregnant women who were diagnosed with umbilical artery thrombosis. The control group recruited pregnant woman with three umbilical vessels or those with isolated single umbilical artery (iSUA) who were matched with umbilical artery thrombosis group. The risk factors and perinatal outcomes were compared between the groups. RESULTS Preconception BMI (OR [95%CI]: 1.212 [1.038-1.416]), abnormal umbilical cord insertion (OR [95%CI]: 16.695 [1.333-209.177]) and thrombophilia (OR [95%CI]: 15.840 [1.112-223.699]) were statistically significant risk factors for umbilical artery thrombosis. An elongated prothrombin time (OR [95%CI]: 2.069[1.091-3.924]) was strongly associated with the occurrence of UAT. The risks of cesarean delivery, preterm birth, fetal growth restriction, neonatal asphyxia, and intraamniotic infection were higher in pregnancies with UAT than in pregnancies with three umbilical vessels or isolated single umbilical artery (P<0.05). Additionally, the incidence of thrombophilia was higher in pregnant women with umbilical artery thrombosis than those with isolated single umbilical artery (P = 0.032). Abnormal umbilical cord insertion was also found to be associated with an elevated risk of iSUA (OR [95%CI]: 15.043[1.750-129.334]). CONCLUSIONS Abnormal umbilical cord insertion was the risk factor for both umbilical artery thrombosis and isolated single umbilical artery. The pregnancies with umbilical artery thrombosis had a higher risk of the adverse perinatal outcomes.

Abstract
BACKGROUND Preliminary evidence suggests that inherited hypercoagulable disorders can lead to an increased risk of significant liver fibrosis. OBJECTIVE We aimed to investigate the prevalence of significant fibrosis in patients with inherited thrombophilia, assessed by using liver stiffness (LS), and to compare this prevalence to that found in a large population-based cohort from the same region. METHODS This was a single-center, cross-sectional study. A complete laboratory analysis for liver disease, LS by transient elastography and an abdominal ultrasound were performed in patients with inherited thrombophilia diagnosed between May 2013-February 2017. These patients were propensity score matched (ratio 1:4) with a population-based cohort from the same region (PREVHEP-ETHON study; NCT02749864; N = 5988). RESULTS Of 241 patients with inherited thrombophilia, eight patients (3.3%) had significant fibrosis (LS ≥8 kPa). All of them had risk factors for liver disease and met diagnostic criteria for different liver diseases. After matching 221 patients with thrombophilia with 884 patients of the PREVHEP-ETHON cohort, the prevalence of significant fibrosis was similar between both cohorts (1.8% vs. 3.6%, p = 0.488). Multivariate analysis showed that age and liver disease risk factors, but not belonging to the thrombophilia cohort, were associated with the presence of significant fibrosis. The magnitude of the increased risk of significant fibrosis in patients with risk factors for liver disease was also similar in both cohorts. CONCLUSIONS Our findings do not provide evidence supporting an association between inherited thrombophilia and an increased risk of significant liver fibrosis, independent of the presence of liver-related causes of fibrosis.

Abstract
INTRODUCTION D-dimer has a high negative predictive value for the diagnosis of venous thromboembolic disease (VTE). However, VTE has been reported in the presence of normal D-dimer values. METHODS This is a prospective observational study in patients with VTE from Hospital Gregorio Marañón between 2001 and 2022, comparing the characteristics of clinical presentation based on D-dimer levels (<500 ng/mL vs. ≥500 ng/mL). RESULTS A total of 2582 patients were found, 333 patients (12.9%) presented negative or weakly positive D-dimer levels. They were significantly younger (57.9 vs. 65.3 years), with a lower prevalence of comorbidities (ischemic heart disease, dementia, and chronic kidney disease), and a greater family history of VTE (8.4% vs. 5.2%) and thrombophilia (11.7% vs. 7.8%). They presented significantly less dyspnea (57.6% vs. 75.4%), syncope (3% vs. 13.5%), less thrombotic load, elevated NT-pro-BNP (22.0% vs. 48.2%), and right ventricle dilatation (8.1% vs. 30.0%). CONCLUSION Patients with VTE and low D-dimer levels at diagnosis were younger, with milder clinical presentation and lower thrombotic load; but they presented a higher prevalence of thrombophilia and a family history of VTE.

Abstract
Recurrent pregnancy loss (RPL) is one of the most challenging and difficult areas of reproductive treatment due to the immense emotional suffering inflicted on families and couples affected by RPL. As a result, it is predicted that couples experiencing recurrent pregnancy loss would have an increase in marital problems, stress levels, and anxiety, preventing them from achieving their family goals. The current cross-sectional study aimed to target pregnant women with thrombophilia with a history of RPL to observe their intimacy problems, stress levels, and couple satisfaction by completing a series of digital questionnaires. These patients were considered as the reference group, while the control group was formed by other women with thrombophilia and a history of RPL who eventually achieved pregnancy and gave birth. A total of 238 complete questionnaires were recorded (157 in the reference group and 81 in the control group). It was observed that women in the reference group who did not give birth had a significantly higher proportion of three or more pregnancy attempts (54.1% vs. 39.5%) and a significantly higher proportion of three more pregnancy losses (68.8% vs. 55.6%). It was observed that patients in the reference group were more likely to be emotion-oriented (42.7% vs. 27.2%). Also, women in the reference group had higher levels of dissatisfaction and lower levels of self-acceptance, pleasure, and marital quality scores. The total SII and DSCS scores were significantly lower than women with thrombophilia with a history of RPL who eventually gave birth. Women from the reference group had significantly greater intimacy problems and stress levels while having lower openness scores and self-esteem scores than women in the control group. It is possible that women with thrombophilia and recurrent pregnancy loss are more dissatisfied with their marriages than those who subsequently had one child. Since the financial status of those who achieved pregnancy was observed to be higher, it is likely that they achieved pregnancy by ART interventions, as they reported in questionnaires. It is important to target families afflicted by thrombophilia and other reasons for infertility to ease their access to ART therapies. By achieving their objectives, affected families will minimize dissatisfaction, divorce rates, and stress.

Abstract
Recurrent Pregnancy Loss (RPL) affects between 1% to 5% of women of reproductive age. It is widely believed that RPL is a complex disorder that is influenced by chromosomal abnormalities, genetic mutations, uterine anatomic deformity, endocrine dysfunction, immunologic factors, infections, and the environment. Thrombotic disorders are a frequent cause of RPL, accounting for almost half of all cases; however, in the rest of the cases, the cause of RPL remains unclear. Therefore, in this study, it was planned to determine the genetic mutations involved in RPL during the first and second trimester of pregnancy. An observational retrospective cohort study was conducted in 2021, collecting data from 157 first trimester miscarriages and 54 s trimester pregnancies. All patients with a panel of laboratory and genetic analysis for thrombophilia were included for data analysis. It was observed that four factors were significantly more prevalent in one of the groups. Factor V Leiden (FVL) homozygosity and antiphospholipid syndrome (APS) antibodies were statistically significantly more common in pregnant women who suffered first trimester pregnancy losses. On the other hand, Protein C deficiency and Glycoprotein Ia polymorphism were statistically significantly more frequent in the second trimester group. The strongest independent risk factors for first trimester pregnancy loss were FVL and prothrombin (PT) compound mutations (OR = 3.11), followed by FVL homozygous mutation (OR = 3.66), and APS antibodies (OR = 4.47). Regarding second trimester pregnancy loss risk factors, the strongest were FVL and PT compound (OR = 3.24), followed by Glycoprotein Ia polymorphism (OR = 3.61), and respectively, APS antibodies (OR = 3.85). Numerous thrombophilic risk factors for early and late pregnancy loss have been found, including several mutations that seem to occur more often either during the first or the second trimester. Even though we are aware of risk-free and efficient diagnostics for thrombophilia abnormalities, no intervention has been proved to be clearly successful after the detection of these variables.

Abstract
In order to reveal the correlation between the prevalence of venous thromboembolism in Kazak pregnant and lying-in women in Xinjiang, the polymorphisms in the promoter region and coding region of the TAFI gene and the interaction of environmental factors are investigated. In this study, determination and analysis of anticoagulation indexes are conducted. The activity of antithrombin III and protein C is measured by chromogenic substrate method, and the activity of protein S is measured by coagulation method. Besides, the detection of APC-R is performed by APC-APTT method. The experimental results show that the prevalence rate of hereditary thrombophilia + DVT among Kazak pregnant women in Xinjiang is 33.8%, and the prevalence rates of AT-III deficiency, PC deficiency, PS deficiency, APCR, and Hcy are 17.5%, 16.7%, 22.0%, 23.7%, and 26.8%, respectively. Also, the genotype frequency and allele frequency distribution of each group are in line with Hardy-Weinberg equilibrium (P > 0.05). The comparison result indicates that the gene frequency has reached a genetic balance and is representative of the population. It is clearly evident that the polymorphisms of prothrombin gene rs3136447 and rs5896 may be associated with hereditary thrombophilia in Xinjiang Kazaks.

Abstract
INTRODUTION Retinal vein occlusion (RVO) has been related to vascular risk factors and thrombophilia. METHODS This is a prospective cohort study of all patients diagnosed with RVO and referred to an Internal Medicine clinic of a tertiary teaching hospital during a 10-year period. Clinical, laboratory and supra-aortic trunks ultrasound variables were analysed and compared according to age. RESULTS Some 309 patients diagnosed with RVO were included, 25 of them younger than 50 years. The prevalence of high blood pressure, dyslipidaemia, diabetes mellitus, hyperhomocysteinemia, and carotid plaque was significantly higher in patients >50 years than in those below. However, the prevalence of inherited thrombophilia was higher in the younger group (32.0% vs 11.4%; p = 0.005). Uncommon diseases related to RVO such as hepatitis C, thalassemia minor, Lyme disease, vasculitis, and periphlebitis were observed in young patients without vascular risk factors. CONCLUSION We suggest performing a genetic thrombophilia study in RVO patients younger than 50 years, while an exhaustive control of vascular risk factors is always recommended in all RVO patients. Moreover, we suggest bearing in mind uncommon diseases related to RVO, especially in young patients without vascular risk factors.

Abstract
OBJECTIVE There are numerous studies reporting a disproportionally high prevalence of thrombophilia in women with a history of recurrent miscarriage (RM), which has led to overdiagnosis and treatment without an improvement in clinical outcomes. The objective of our study was to assess the prevalence of inherited and acquired thrombophilia in a large cohort of women with a history of early RM using internationally agreed diagnostic criteria and inclusion parameters and compare it to the meta-analysis results of existing literature. METHODS DESIGN: Retrospective cohort study and systematic review of literature. SETTING This is a retrospective cohort study set-up in two dedicated tertiary centres for women with RM in Southwest London and Surrey. We reviewed all the available literature related to causes of RMs. We ascertained the prevalence of thrombophilia in the study population and compared it with historical and published prevalence in the general population. PARTICIPANTS 1155 women between 2012 and 2017. All patients had three or more first trimester miscarriages and a full thrombophilia screen. RESULTS The overall prevalence of thrombophilia in our study population is 9.2% (106/1155) with 8.1% (94/1155) of cases positive for inherited thrombophilia, which is similar to the general population; Factor V Leiden (4.9%; 57/1155) and prothrombin gene mutation (2.9%; 34/1155) were the most common inherited thrombophilias, while only 1% (12/1155) tested positive for acquired thrombophilia. Persistent positive lupus anticoagulant (LA) was found in 0.5% (6/1155) and persistent positive anticardiolipin (ACL) antibodies with a value ≥40 U/mL was found in 0.5% (6/1155) of patients. Tests for LA/ACL were performed a minimum of 12 weeks apart thus meeting the revised Sapporo criteria for a diagnosis of antiphospholipid syndrome. CONCLUSION The findings of our study demonstrate that the prevalence of inherited thrombophilia is similar in women with RM to that in the general population. Similarly, the prevalence of acquired thrombophilia, using the revised Sapporo criteria, in the cohort of RMs is similar to that in the general population. Therefore, we do not recommend investigation or treatment of inherited or acquired thrombophilia in women with RM. PROSPERO REGISTRATION NUMBER CRD42020223554.

Abstract
Osteonecrosis of the jaws (ONJ) usually has a clear etiology. Local infection or trauma, radiotherapy and drugs that disrupt the vascular supply or bone turnover in the jaws are its major contributors. The thrombotic occlusion of the bone’s venous outflow that occurs in individuals with hereditary thrombophilia and/or hypofibrinolysis has a less known impact on jaw health and healing capability. Our research provides the most comprehensive, up-to-date and systematized information on the prevalence and significance of hereditary thrombophilia and/or hypofibrinolysis states in ONJ. We found that hereditary prothrombotic abnormalities are common in patients with ONJ refractory to conventional medical and dental treatments. Thrombophilia traits usually coexist with hypofibrinolysis traits. We also found that frequently acquired prothrombotic abnormalities coexist with hereditary ones and enhance their negative effect on the bone. Therefore, we recommend a personalized therapeutic approach that addresses, in particular, the modifiable risk factors of ONJ. Patients will have clear benefits, as they will be relieved of persistent pain and repeated dental procedures.

Abstract
OBJECTIVES The role of hereditary thrombophilia in reproductive failure (RF) is strongly debatable. In this retrospective single-center study, we analyzed pregnancy outcome in 175 women screened for thrombophilia after at least one event of RF. RESULTS The prevalence of thrombophilia in our cohort was 33.4%. Pregnancy survival curves were not different according to severity (log-rank, p = 0.302) or type of thrombophilia (log-rank, p = 0.532). In total, 81.7% of 175 subsequent pregnancies were proceeded with LMWH. Concomitant use of ASA was prescribed in 75 pregnancies according to physician choice. The primary endpoint was live birth rate (LBR) that succeeded in 152/175 next pregnancies (86.8%) and late obstetric complications (LOBC) which occurred in 17/175 next pregnancies (9.8%). In logistic regression analysis, neither the severity nor the type of thrombophilia was important for any pregnancy outcome (LBR or LOBC). Considering therapeutic interventions, the use of LMWH ± ASA was not related to LBR or LOBC. The only factor inversely related to LBR was age above the cutoff value of 35.5 years (p = 0.049). CONCLUSIONS Incidence of thrombophilia is increased among women with RF, but the severity or type of thrombophilia is not related to pregnancy outcome.

Abstract
The SARS-CoV-2 is a new coronavirus responsible for the COVID-19 disease and has caused the pandemic worldwide. A large number of cases have overwhelmed the healthcare system worldwide. The COVID-19 infection has been associated with a heightened risk of thromboembolic complications. Various mechanisms are leading to the high thrombotic risk in COVID-19 patients such as inflammation, endotheliitis, hyperviscosity, and hypercoagulability. We searched PubMed, EMBASE, and CINAHL from January 2020 to December 2020. We used the following search terms: COVID-19, coagulopathy, and thrombosis. We reviewed the epidemiology, clinical features, mechanisms, and treatment of COVID-19-associated coagulopathy.

Abstract
BACKGROUND Although ovarian clear cell carcinoma (CCC) is associated with high incidence of thromboembolism, the clinicopathological and biological significance of hypercoagulable status in CCC remains unclear. MATERIALS AND METHODS We retrospectively analyzed pretreatment D-dimer levels, thromboembolic status, and clinical outcome of 125 CCCs in the discovery set and 143 CCCs in two other independent validation sets. Next, we performed RNA sequencing of 93 CCCs and compared coagulation-related gene profiles with 2492 pan-cancer data. We investigated differences in molecular characteristics of CCC subclasses based on coagulation status. RESULTS In the discovery dataset, D-dimer elevation above the normal range was significantly associated with shorter progression-free and overall survival, irrespective to thromboembolic status. Multivariate analysis identified D-dimer elevation and clinical stage as an independent prognostic factors. We confirmed the prognostic significance of D-dimer elevation in the validation sets. Tissue factor and IL6, which are considered key elements of cancer-induced hypercoagulation, were highly expressed in CCC than in other cancers regardless of D-dimer level. Higher activity of various oncogenic pathways was observed in CCC with compared to without D-dimer elevation. Moreover, hierarchical cluster analysis divided 57 CCCs with D-dimer elevation into immunologically hot and cold tumor subtypes. Hot tumors were characterized by enrichment of T-cell inflamed phenotype, inflammation, the epithelial-mesenchymal transition, and high serum levels of CRP, and cold tumors by enrichment of cell cycle and MYC pathways. CONCLUSIONS CCC represents hypercoagulable disease and elevate D-dimer is a prognostic factor for decreased survival in CCC. D-dimer high CCC has distinct molecular characteristics into the inflammatory-driven pathway (hot tumor) and the immune-suppressive pathway (cold tumor). Treatment implication of our proposed molecular classification merits further investigation.

Abstract
Cushing's syndrome (CS) is associated with multisystemic complications; the hematological system is not spared. Alteration in hemostatic parameters and in vivo endothelial dysfunction lead to increased thrombotic events. Arterial and venous thrombotic events carry significant morbidity and mortality. Death from cardiovascular and pulmonary embolism account for more than 50% of mortality. Surgery is a critical period; close to 50% of events occur in the 1-2 months after intervention. The evaluation and risk stratification of patients with CS is key to prevent events, balancing the risk-benefit of anticoagulation in this population. This current review will focus on up-to-date data on epidemiology, pathophysiology and management of hypercoagulability in CS.

Abstract
BACKGROUND A significant proportion of patients with coronavirus disease 19 (COVID-19) suffer from excessive coagulation activation and coagulopathy which is associated with an increased risk of venous and arterial thromboembolism and adverse outcome. Our study investigates coagulation markers and the incidence of thromboembolic events in COVID-19 patients receiving recommended anticoagulation strategies. METHODS In a retrospective single-center analysis at the University Hospital Zurich, Switzerland, we investigated 31 adult COVID-19 patients between April 6th and May 13th, 2020 and with at least one laboratory assessment of the coagulation markers prothrombin time/Quick, thrombin time, fibrinogen and D-dimers. For antithrombotic prophylaxis low-molecular-weight-heparin or unfractionated heparin was administered and two patients with heparin-induced thrombocytopenia received argatroban. RESULTS We analyzed 31 patients (68% male, mean age 60± SD 15 years). 22 (71%) of these required intensive care unit treatment, 5 (16%) were hospitalized in a ward, and 4 (13%) were outpatients. Mean fibrinogen levels were markedly elevated to 6.4± SD 1.8g/l, with a peak in the third week of the disease and no significant decrease over time. D-dimers were elevated to a mean value of 5.1±4.4mg/l with peak levels of 6.8±5.3mg/l in the fourth week of disease, and a subsequent decrease. Platelet count (308±136G/l) and PT/Quick (85±22%) showed no significant changes over time. Sensitivity analyses for patients treated in the ICU showed that D-dimer levels were higher in this group. The results of other sensitivity analyses were comparable. Thromboembolic events were diagnosed in 4 (13%) patients and 5 (16%) patients died during the observation period. CONCLUSION We find coagulation alterations in COVID-19 patients indicating significant hypercoagulability. These alterations are visible despite antithrombotic treatment, and peak around week 3-4 of the disease.

Abstract
Thrombotic complications are frequent in COVID-19 and contribute significantly to mortality and morbidity. We review several mechanisms of hypercoagulability in sepsis that may be upregulated in COVID-19. These include immune-mediated thrombotic mechanisms, complement activation, macrophage activation syndrome, antiphospholipid antibody syndrome, hyperferritinemia, and renin-angiotensin system dysregulation. We highlight biomarkers within each pathway with potential prognostic value in COVID-19. Lastly, recent observational studies have evaluated a role for the expanded use of therapeutic anticoagulation in COVID-19. We review strengths and weaknesses of these studies, and we also discuss the hypothetical benefit and anticipated challenges of fibrinolytic therapy in COVID-19.

Abstract
Infection from severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), though mainly a respiratory disease, can impair many systems, including causing hematological complications. Lymphopenia and hypercoagulability have been reported in adults with coronavirus disease 2019 (COVID-19) and are considered markers of poor prognosis. This review summarizes the hematological findings in children with SARS-CoV-2 infection. The majority of infected children had a normal leukocyte count, while the most common white blood cell abnormality was leukopenia. Lymphopenia, which may be a marker of severe disease, was rarer in children than in adults, possibly due to their immature immune system or due to the less severe manifestation of COVID-19 in this age group. Age may have an impact, and in neonates and infants the most common abnormality was lymphocytosis. Abnormalities of red blood cells and platelets were uncommon. Anemia and hypercoagulability were reported mainly in children presenting the novel multisystem inflammatory syndrome (MIS) associated with SARS-CoV-2.

Abstract
BACKGROUND Retinal vascular occlusion is a leading cause of sight loss. Both retinal artery occlusion (RAO) and retinal vein occlusion (RVO) have been associated with hypercoagulable states; however, the burden of thrombophilia in these patients is unclear. OBJECTIVES This study aims at estimating the prevalence of inherited and acquired thrombophilias in adults with RAO or RVO through a systematic review and meta-analysis of the literature. PATIENTS/METHODS PubMed and EMBASE were systematically searched from inception to 29 February 2020. All studies reporting prevalences of factor V Leiden (FVL) and prothrombin (F-II) G20210A mutations, methylenetetrahydrofolate reductase (MTHFR) C677T and plasminogen activator inhibitor (PAI) 4G polymorphisms, antithrombin III (AT-III), protein C (PC) and protein S (PS) activity deficiencies, hyperhomocysteinemia, and antiphospholipid (APL) antibodies in adults with RAO or RVO were included. Pooled prevalences and 95% confidence intervals (CI) were calculated. RESULTS Ninety-five studies were included; FVL and F-II mutations were found in 6% (95% CI: 5-8) and 3% (95% CI: 2-4) of individuals with RVO, respectively, whereas AT-III, PC, and PS activity deficiencies were found in <2%. The MTHFR C677T and PAI 4G homozygous polymorphism were observed in 13% (95% CI: 10-17) and 23% (95% CI: 16-31) of RVO, respectively; 8% presented APL antibodies. Similar findings were observed in individuals with RAO. CONCLUSIONS Compared with healthy subjects, patients with retinal vascular occlusion showed similar prevalences of inherited and acquired thrombophilias. These findings do not support routine thrombophilia screening in individuals with RAO or RVO.

Abstract
The 2019 coronavirus disease (COVID-19) presents with a large variety of clinical manifestations ranging from asymptomatic carrier state to severe respiratory distress, multiple organ dysfunction and death. While it was initially considered primarily a respiratory illness, rapidly accumulating data suggests that COVID-19 results in a unique, profoundly prothrombotic milieu leading to both arterial and venous thrombosis. Consistently, elevated D-dimer level has emerged as an independent risk factor for poor outcomes, including death. Several other laboratory markers and blood counts have also been associated with poor prognosis, possibly due to their connection to thrombosis. At present, the pathophysiology underlying the hypercoagulable state is poorly understood. However, a growing body of data suggests that the initial events occur in the lung. A severe inflammatory response, originating in the alveoli, triggers a dysfunctional cascade of inflammatory thrombosis in the pulmonary vasculature, leading to a state of local coagulopathy. This is followed, in patients with more severe disease, by a generalized hypercoagulable state that results in macro- and microvascular thrombosis. Of concern, is the observation that anticoagulation may be inadequate in many circumstances, highlighting the need for alternative or additional therapies. Numerous ongoing studies investigating the pathophysiology of the COVID-19 associated coagulopathy may provide mechanistic insights that can direct appropriate interventional strategies.

Abstract
BACKGROUND Antiphospholipid syndrome (APS) is an acquired thrombophilia disorder with prevalence not completely known in patients with first unprovoked venous thromboembolic events (VTE). Recent data suggest that the management of some APS patients should be different from that of patients with other thrombophilia. Our aim was to estimate the prevalence of APS in a community-based cohort of patients with a first unprovoked VTE. METHODS We conducted a cross-sectional study analyzing data from our computer assisted oral anticoagulant dosage program. Data of all consecutive patients aged 18 to 50 years who were seen between January 1, 2002 and December 31, 2011 for a first proximal unprovoked VTE were extracted. The prevalence and main features of patients who fulfilled the Sapporo revised criteria for APS were collected. RESULTS AND DISCUSSION A total of 524 incident patients aged 18 to 50 years were included in the anticoagulation clinic during the study period. Of them, 491 were tested for APS and 44 (9.0%; 95% confidence interval [CI]: 6.7-11.8) fulfilled APS criteria. Of 26 APS women, 8 (30.8%) were on combined oral contraceptive pill at the time of VTE, versus 108 (55.1%) in non-APS women (P = .02). No difference was observed between APS and non-APS patients in terms of gender or type of VTE. The prevalence of APS is high in young patients with a first unprovoked VTE. In the direct oral anticoagulant era, when and how to test for APS is challenging and deserves further investigation.

Abstract
Hypertension during pregnancy and preeclampsia are associated with increased arterial thrombotic risk in later life. Whether these complications are associated with risk of venous thromboembolism (VTE) on the short term after pregnancy and on the long term, that is, outside pregnancy, is largely unknown. We conducted a nationwide cohort study in women with at least 1 pregnancy and their first VTE risk by linking the Dutch perinatal registry (Perined) to anticoagulation clinics. We used Cox proportional hazard models to estimate hazard ratios (HRs) and corresponding 95% CI for VTE risk in women with hypertension during pregnancy, women with preeclampsia, compared with women with uncomplicated pregnancies (reference). A total of 1 919 918 women were followed for a median of 13.7 (interquartile range, 7.6–19.2) years for a total of 24 531 118 person-years in which 5759 first VTEs occurred; incidence rate: 2.3 (95% CI, 2.3–2.4) per 10 000 person-years. In the first pregnancy and 3-month postpartum period, VTE risk was higher in women with hypertension, HR, 2.0 (95% CI, 1.7–2.4), and highest among women with preeclampsia, HR, 7.8 (95% CI, 5.4–11.3), versus the reference group. On the long term, women with hypertension during pregnancy and preeclampsia had a higher VTE risk: HR, 1.5 (95% CI, 1.4–1.6) and HR, 2.1 (95% CI, 1.8–2.4), respectively, versus the reference group. When excluding events during pregnancy and postpartum, these HRs were 1.4 (95% CI, 1.3–1.5) and 1.6 (95% CI, 1.4–2.0), respectively. In conclusion, hypertension during pregnancy and preeclampsia are associated with an increased VTE risk during pregnancy and postpartum period and in the 13 years after.

Abstract
Thrombotic complications of the novel coronavirus (COVID-19) are a concerning aspect of the disease, due to the high incidence in critically ill patients and poor clinical outcomes. COVID-19 predisposes patients to a hypercoagulable state, however, the pathophysiology behind the thrombotic complications seen in this disease is not well understood. Several mechanisms have been proposed and the pathogenesis likely involves a host immune response contributing to vascular endothelial cell injury, inflammation, activation of the coagulation cascade via tissue factor expression, and shutdown of fibrinolysis. Treatments targeting these pathways may need to be considered to improve clinical outcomes and decrease overall mortality due to thrombotic complications. In this review, we will discuss the proposed pathophysiologic mechanisms for thrombotic complications in COVID-19, as well as treatment strategies for these complications based on the current literature available.

Abstract
Environmental pollution is an important modifiable determinant for preventing cardiovascular diseases. Acute exposure to air pollution is linked to severe adverse cardiovascular events, including venous thromboembolism risk. The adverse health effects seem to arise from blood-borne metals and transition metal components from exposure to particulate matter that, when breathed, passes through the lungs into the heart and the blood stream. Pollution affects health via mechanisms including oxidative stress and inflammation, and metals may have a detrimental effect on both the blood cells, particularly platelets, and circulation. Some evidences demonstrates atherotrombotic consequences of acute and chronic exposure to air pollution, but few studies have examined exposure effects on the prothrombotic biomarkers leading to venous thromboembolism. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, we performed a systematic review (14 papers) of the past twelve years, focusing on the relationship between inhalable airborne metal exposures and coagulative biomarker disorders leading to lower limb venous thromboembolisms, e.g., deep vein thrombosis. Results support the hypothesis that exposure to inhalable metals, as elemental compounds in particulate matter, cause changes or activation of a number of human prothrombotic hemostatic biomarkers.

Abstract
Background Inherited thrombophilias are well-established predisposing factors for venous thromboembolism, but their role in arterial thrombosis, such as arterial ischemic stroke, remains uncertain. We aimed to evaluate the association between inherited thrombophilia (factor V Leiden, prothrombin G20210A mutation, protein C deficiency, protein S deficiency, and antithrombin deficiency) and risk of arterial ischemic stroke in adults. Methods and Results We searched PubMed, EMBASE, and Cochrane Library Databases from inception to December 31, 2018. We included case-control or cohort studies of adults reporting the prevalence of inherited thrombophilias in those with arterial ischemic stroke and subjects without arterial ischemic stroke. Two reviewers (T.C., E.D.) independently searched the literature and extracted data. Pooled odds ratios (ORs) and 95% CIs were calculated using random-effects model. We identified 68 eligible studies, which collectively enrolled 11 916 stroke patients and 96 057 controls. The number of studies reporting factor V Leiden, prothrombin G20210A mutation, protein C deficiency, protein S deficiency, and antithrombin deficiency were 56, 45, 15, 17, and 12, respectively. Compared with controls, patients with arterial ischemic stroke were significantly more likely to have the following inherited thrombophilias: factor V Leiden (OR, 1.25; 95% CI, 1.08-1.44; I2=0%), prothrombin G20210A mutation (OR, 1.48; 95% CI, 1.22-1.80; I2=0%), protein C deficiency (OR, 2.13; 95% CI, 1.16-3.90; I2=0%), and protein S deficiency (OR, 2.26; 95% CI, 1.34-3.80; I2=8.8%). Statistical significance was not reached for antithrombin deficiency (OR, 1.25; 95% CI, 0.58-2.67; I2=8.8%). Conclusions Inherited thrombophilias (factor V Leiden, prothrombin G20210A mutation, protein C deficiency, and protein S deficiency) are associated with an increased risk of arterial ischemic stroke in adults. The implications of these findings with respect to clinical management of patients with ischemic stroke require further investigation.

Abstract
It is unknown whether the risk factor profile for mesenteric venous thrombosis (MVT) is different from systemic venous thromboembolism (VTE). The aim of the present population-based study was to compare acquired and inherited risk factors in MVT versus VTE. Identification of all MVT patients at Skåne University Hospital between 2000 and 2015 was performed in patient records and AuriculA (Swedish anticoagulation registry). VTE patients were retrieved from the Malmö Thrombophilia Study (MATS), including 1465 consecutive unselected VTE patients between 1998 and 2008. Patients with MVT (n = 120) were younger (p < 0.001), had higher glomerular filtration rate (p < 0.001), lower smoking rate (p < 0.001), and had less often undergone recent surgery (p = 0.025). The prevalence of solid cancer (19.2% in MVT versus 12.1% in VTE; p = 0.026) and intra-abdominal cancer (16.7% versus 2.3%; p < 0.001) were higher in MVT. The prevalence of factor V Leiden mutation without presence of cancer was lower in MVT compared to VTE (26.6% versus 38.9%; p = 0.031). Thirty-day mortality was higher in the MVT group (9.2% versus 0.6%; p < 0.001), but did not differ at long-term follow-up according to Kaplan–Meier analysis (p = 0.73). Patients with MVT have a higher prevalence of cancer and lower prevalence of factor V Leiden mutation than those with systemic VTE. Intra-abdominal cancer should be excluded in MVT patients, and the high prevalence of factor V Leiden mutation in patients without cancer in both groups suggests that screening for thrombophilia in patients without cancer should be considered in this population for both groups.

Abstract
Essentials We investigated direct oral anticoagulant (DOAC) use in venous thromboembolism and thrombophilia. A comprehensive search identified 10 studies, 8 of which were included in a meta-analysis. DOACs were overall safe and effective in patients with venous thromboembolism and thrombophilia. Efficacy/safety of DOACs was maintained in low-risk antiphospholipid syndrome patient subgroup. SUMMARY: Background Direct oral anticoagulants (DOACs) are increasingly used in acute and long-term treatment of venous thromboembolism (VTE). However, their role in management of thrombophilia-associated VTE is controversial. Methods Through a comprehensive search on MEDLINE, Cochrane Library, and Clinicaltrials.gov, we identified 10 eligible studies, 8 of which reporting data on 1994 thrombophilia patients were included in a random-effects meta-analysis. Eligible studies were phase 2 to 3 randomized controlled trials comparing DOACs to vitamin K antagonists (VKAs) in patients with VTE, including those with thrombophilia. Results Of eight studies included in meta-analysis, four evaluated rivaroxaban, three dabigatran, and one edoxaban. No results could be obtained on apixaban use. The rates of VTE recurrence (RR, 0.70; 95% CI, 0.34-1.44; I2 = 0%) and major/clinically relevant non-major bleeding events (RR, 0.92; 95% CI, 0.62-1.36; I2 = 23%) were similar between thrombophilia patients treated with DOACs compared to VKAs. Results were comparable to findings in patients without known thrombophilia: RR, 1.02; 95% CI, 0.80-1.30; I2 = 46% for VTE recurrence and RR, 0.72; 95% CI, 0.57-0.90; I2 = 84% for major/clinically relevant non-major bleeding events. Conclusions Rates of VTE recurrence and bleeding events were both low and comparable in patients with various thrombophilias receiving either treatment, suggesting that DOACs are an appropriate treatment option in this population. Due to limited data, it is unclear whether these findings apply to specific subgroups such as high-risk antiphospholipid syndrome, uncommon thrombophilias, or the use of apixaban.

Abstract
OBJECTIVES To investigate the incidence of inherited thrombophilias in patients with adverse obstetric outcomes and to compare detection rates of thrombophilias between standard blood tests and a novel genetic test. METHODS This is a case-control prospective study performed in Hospital Sant Joan de Déu in Barcelona, Spain. Cases had a history of intrauterine growth restriction requiring delivery before 34 weeks gestation, placental abruption before 34 weeks gestation, or severe preeclampsia. Controls had at least two normal, spontaneously conceived pregnancies at term, without complications or no underlying medical disease. At least 3 months after delivery, all case and control women underwent blood collection for standard blood tests for thrombophilias and saliva collection for the genetic test, which enables the diagnosis of 12 hereditary thrombophilias by analyzing genetic variants affecting different points of the blood coagulation cascade. RESULTS The study included 33 cases and 41 controls. There were no statistically significant differences between cases and controls in the standard blood tests for thrombophilias in plasma or the TiC test for genetic variables. One clinical-genetic model was generated using variables with the lowest P values: ABO, body mass index, C_rs5985, C_rs6025, and protein S. This model exhibited good prediction capacity, with an area under the curve of almost 0.7 (P <0.05), sensitivity of almost 67%, and specificity of 70%. CONCLUSION Although some association may exist between hypercoagulability and pregnancy outcomes, no significant direct correlation was observed between adverse obstetric outcomes and inherited thrombophilias when analyzed using either standard blood tests or the genetic test. Future studies with a larger sample size are required to create a clinical-genetic model that better discriminates women with a history of adverse pregnancy outcomes and an increased risk of poor outcomes in subsequent pregnancies.

Abstract
Livedoid vasculopathy is a rare thrombotic cutaneous disease. This observational study aimed to assess the clinical and biological features of livedoid vasculopathy and the efficacy of treatments. Patients enrolled had typical livedoid vasculopathy both clinically and histologically. Investigation of thrombophilia was performed. Electromyography was undertaken in the presence of symptoms suggesting peripheral neuropathy. Eighteen women and 8 men were included, with a mean age of 35.5 years at onset. Twenty patients had at least one thrombophilia factor. Ten patients had a peripheral neuropathy with 2 of these patients demonstrating a specific thrombo-occlusive vasculopathy on muscle biopsy. Anticoagulation with low molecular weight heparin was the most prescribed therapy and was associated with the best outcome (effective in 14 patients). Eight patients had severe disease refractory to anticoagulation and required intravenous immunoglobulins, producing a good response in 6 patients.

Abstract
Platelet count represents a useful tool in clinical practice to discriminate individuals at higher risk of bleeding. Less obvious is the role of platelet count variability within the normal range of distribution in shaping the individual's disease risk profile. Epidemiological studies have shown that platelet count in the adult general population is associated with a number of health outcomes related to hemostasis and thrombosis. However, recent studies are suggesting a possible role of this platelet index also as an independent risk factor. In this review of adult population studies, we will first focus on known genetic and non-genetic determinants of platelet number variability. Next, we will evaluate platelet count as a marker and/or a predictor of disease risk and its interaction with other risk factors. We will then discuss the role of platelet count variability within the normal distribution range as a contribution to disease and mortality risk. The possibility of considering platelet count as a simple, inexpensive indicator of increased risk of disease and death in general populations could open new opportunities to investigate novel platelet pathophysiological roles as well as therapeutic opportunities. Future studies should also consider platelet count, not only platelet function, as a modulator of disease and mortality risk.

Abstract
BACKGROUND AND PURPOSE Peripartum strokes during delivery admissions are rare but have high maternal morbidity. Infections have been proposed as a possible stroke trigger. We hypothesized that women who had infections diagnosed at the time of delivery admission would have higher risk of stroke during their delivery hospitalization. METHODS We conducted a case-control study using state inpatient administrative databases for California (2007-2011), Florida (2009-2011), and New York (2009-2011). Women whose admission included a vaginal or cesarean delivery, with a new diagnosis of stroke during the admission, were considered cases and were randomly matched to 3 in-state controls by age/admission year and presence and severity of hypertensive disorders of pregnancy. The primary exposure of interest was infection of any type present on admission. Secondary exposures included race/ethnicity, payer status, delivery method, and known vascular risk factors such as chronic hypertension, diabetes mellitus, smoking, alcohol abuse, hypercoagulable states, coagulopathies, and renal disease. We used multivariable conditional logistic regression to estimate the odds ratios and 95% confidence intervals for the association of infections and known vascular risk factors with stroke risk. RESULTS A total of 455 cases (mean age, 29.8), of whom 195 (42.9%) had hypertensive disorders of pregnancy, were matched with 1365 controls. Infection of any type present on admission increased the odds of stroke diagnosis during the admission (adjusted odds ratio, 1.74; 95% confidence interval, 1.29-2.35). Risk was higher for genitourinary infections (adjusted odds ratio, 2.56; 95% confidence interval, 1.25-5.24) and sepsis (adjusted odds ratio, 10.4; 95% confidence interval, 2.15-20.0). The association between infection and stroke during delivery admission did not differ by the presence of hypertensive disorders of pregnancy. CONCLUSIONS Infections present on admission increased stroke risk during delivery admissions in women with and without hypertensive disorders of pregnancy. The results were driven by genitourinary infections and sepsis. Infections may be an underrecognized precipitant of peripartum stroke.

Abstract
SummaryWe assessed the predictive value of D-dimer levels in combination with residual venous obstruction (RVO) for recurrent venous thromboembolism (VTE) in a prospective cohort of outpatients after oral anticoagulant therapy (OAT) suspension for a first episode of idiopathic proximal deep vein thrombosis of the lower limbs during a 2-year follow-up. Patients (n=400) were enrolled on the day of OAT suspension when RVO was determined by compression ultrasonography (present in 48.6% of patients). D-dimer (cut-off value: 500 ng/mL) was measured 30±10 days afterwards (abnormal in 56.4% of patients). The overall recurrence rate was 16.7% (67/400; 95% confidence intervals - CI -:13–21%). The multivariate hazard ratio (HR) for recurrence was 3.32 (95% CI:1.78–6.75; p > 0.0001) for abnormal D-dimer compared to normal D-dimer and 1.2 (95% CI:0.72–2.07; p>0.05) for RVO compared to absent RVO. The recurrence rate was 5.7% (95% CI:2–13%) and 10.4% (95% CI:6–18%), respectively, for normal D-dimer either without or with RVO, 22.9% (95% CI:14–33%) and 25.9% (95% CI: 18–35%), respectively, for abnormal D-dimer, either without or with RVO. When compared with normal D-dimer without RVO, the multivariate HR for recurrence was similar for abnormal D-dimer either with RVO (4.76 – 95% CI:1.78–12.8) or without RVO (4.3–95%:1.56–11.88). Abnormal D-dimer at one month after OAT withdrawal is an independent risk factor for recurrent VTE, while RVO at the time of OAT withdrawal, either with normal or abnormal D-dimer after one month, does not influence the risk of recurrence.

Abstract
SummaryThe etiology and pathophysiology of cerebral sinus venous thrombosis (CSVT) in the paediatric population is still poorly understood, and the role of thrombophilic risk factors remains to be elucidated. In our multi-center case-controlled study we studied 46 patients with CSVT diagnosed from April 1996 to December 2003, consecutively referred for thrombophilia work-up. The results of thrombophilia screen were compared to 112 healthy paediatric controls. Anticoagulant therapy was applied according to treating physicians’ decisions, and all cases were prospectively followed for a median of 4.1 years. Of 46 children, 8 had CSVT diagnosed in the neonatal period and therefore were analyzed separately. The prevalence of single thrombophilia markers and combinations of thrombophilic risk factors were similar among cases and controls. Among children with CSVT co-morbid systemic illness was present in most patients at diagnosis. Seven out of 8 children with idiopathic CSVT had thrombophilic risk factors as compared to 31/38 patients with co-morbid conditions. Anticoagulation was initiated in most patients, 11/46 patients continued therapy for a total of one year or more post event. Neither clinical presentation nor initial treatment decisions were affected by presence of thrombophilic risk factors in our study group. Thrombophilia prevalence was not increased in children with CSVT as compared to controls, however thrombophilia was more frequent among children with idiopathic CSVT. Thus, those selected patients would benefit most from thrombophilia work-up, required for long-term therapy considerations.

Abstract
SummaryRetinal vein occlusion (RVO) is a multifactorial disease involving vessel damage, stasis, viscosity and thrombosis. Conflicting findings on hereditary thrombophilic risk factors have been reported and their impact on RVO features remains to be defined. The aim of the present study was to evaluate the prevalence of hereditary thrombophilic risk factors (HTRF) and characteristics of RVO in patients with or without HTRF. The design of the study was a prospective, observational case series. Two hundred and thirty-four patients with RVO were included consecutively. A French healthy population of the same region was studied as control group. The HTRF studied were protein C (PC), protein S (PS) and antithrombin (AT) deficiencies, factor V Leiden (FVL) and factor II 20210A polymorphisms. Chi-Square was used for comparison with the healthy subjects and between RVO patient with and without HTRF according to localisation (branch vs. central), type of RVO (ischemic or non-ischemic), recurrence, age at first event and classical vascular risk factors. Twenty-two patients had HTRF (12 FV Leiden heterozygotes, 9 FII 20210A heterozygotes and 1 PS deficiency). No AT or PC deficiency was detected. Frequencies of PS deficiency, FVL and FII 20210A allele were similar to the reference population as well as to published data in the general caucasian population. Eighty-six patients experienced their first episode before the age of 60 years. Systemic hypertension, glaucoma and angina were significantly less frequent in patients with RVO before 60 years. Fourteen of the 22 patients with one HTRF (64%) experienced their first episode of RVO before the age of 60 years compared to 72 of 212 without HTRF (34%) (p = 0.006). Heterozygote status for FV Leiden was significantly more frequent in patients who had experienced their first episode of RVO before 60 years (p = 0.027). In conclusion, this study suggests a role of FV Leiden in the occurrence of RVO in patients younger than 60 years who exhibit fewer acquired vascular risk factors than in older patients.

Abstract
Laboratory costs of thrombophilia testing exceed an estimated $650 million (in US dollars) annually. Quantifying the prevalence and financial impact of potentially inappropriate testing in the inpatient hospital setting represents an integral component of the effort to reduce healthcare expenditures. We conducted a retrospective analysis of our electronic medical record to evaluate 2 years' worth of inpatient thrombophilia testing measured against preformulated appropriateness criteria. Cost data were obtained from the Centers for Medicare and Medicaid Services 2016 Clinical Laboratory Fee Schedule. Of the 1817 orders analyzed, 777 (42.7%) were potentially inappropriate, with an associated cost of $40,422. The tests most frequently inappropriately ordered were Factor V Leiden, prothrombin gene mutation, protein C and S activity levels, antithrombin activity levels, and the lupus anticoagulant. Potentially inappropriate thrombophilia testing is common and costly. These data demonstrate a need for institution-wide changes in order to reduce unnecessary expenditures and improve patient care.

Abstract
INTRODUCTION Presumed perinatal ischemic stroke is a frequent cause of neurological sequelae. We aimed to describe the different clinical findings and risk factors and to analyse the differences according the vascular origin. PATIENTS AND METHODS Retrospective, descriptive study of patients diagnosed with presumed perinatal ischemic stroke attended at a tertiary pediatric hospital from 1990 to 2015. RESULTS 44 patients were included. A total of 24 patients (55%) had arterial ischemic stroke and 20 (45%) had periventricular venous infarction. Delay in diagnosis was significantly higher in patients with periventricular venous infarction compared to those with arterial ischemic stroke (14 and 8 months respectively; p = 0.025). Most patients presented with asymmetrical motor development (90%), only < 5% with seizures or non motor delays. Subsequent epilepsy at follow-up was significantly more prevalent in arterial ischemic stroke group (p = 0.020). We determined risk factors theoretically involved in the pathogenesis of presumed perinatal ischemic stroke: prenatal, obstetrical, perinatal, prothrombotic and cardiac. No significant differences between risk factors and vascular origin were found. Prothrombotic abnormalities were common (48.3%). CONCLUSIONS Investigation in risk factors implicated in presumed perinatal ischemic stroke is required to develop prevention strategies. Delay in diagnosis is higher in periventricular venous infarction group.

Abstract
BACKGROUND Based on a number of small observational studies, cerebral venous sinus thrombosis has diverse clinical and imaging features, risk factors, and variable outcome. In a large, multicenter cerebral venous thrombosis (VENOST) study, we sought to more precisely characterize the clinical characteristics of Caucasian patients. METHODS All data for the VENOST study were collected between the years 2000 and 2015 from the clinical follow-up files. Clinical and radiological characteristics, risk factors, and outcomes were compared in terms of age and sex distribution. RESULTS Among 1144 patients 68% were women, and in older age group (>50 years) male patients were more prevalent (16.6% versus 27.8%). The most frequent symptoms were headache (89.4%) and visual field defects (28.9%) in men, and headache (86.1%) and epileptic seizures (26.8%) in women. Gynecological factors comprised the largest group in women, in particular puerperium (18.3%). Prothrombotic conditions (26.4%), mainly methylenetetrahydrofolate reductase mutation (6.3%) and Factor V Leiden mutation (5.1%), were the most common etiologies in both genders. 8.1% of patients had infection-associated and 5.2% had malignancy-related etiology that was significantly higher in men and older age group. Parenchymal involvement constitutively hemorrhagic infarcts, malignancy, and older age was associated with higher Rankin score. Epileptic seizures had no effect on prognosis. CONCLUSIONS Clinical and radiological findings were consistent with previous larger studies but predisposing factors were different with a higher incidence of puerperium. Oral contraceptive use was not a prevalent risk factor in our cohort. Malignancy, older age, and hemorrhagic infarcts had worse outcome.

Abstract
BACKGROUND To determine patient-related risk factors for infection following knee arthroscopy using two large databases. METHODS A private-payer (PP) and Medicare national insurance database were queried for patients undergoing simple knee arthroscopy procedures from 2005 to 2015. Patients undergoing concomitant open or complex procedures with grafts were excluded. Postoperative infection within 90days was assessed using ICD-9 and CPT codes. A multivariate logistic regression analysis was utilized to evaluate patient-related risk factors for postoperative infection. Adjusted odds ratios (OR) and 95% confidence intervals were calculated for each risk factor, with P <0.05 considered statistically significant. RESULTS One hundred thousand three hundred ninety nine patients from the PP database and 629,842 patients from the Medicare database met all inclusion and exclusion criteria. In the PP database, there were 250 patients with documented infections (0.25%); the incidence of infection was similar in the Medicare database (1755 patients, 0.28%). There were numerous patient-related comorbidities and demographics independently associated with a significantly increased risk of postoperative infection that were similar across the PP and Medicare patient populations, respectively, including younger age (OR=1.27, 1.43), morbid obesity (OR=1.26, 1.74), tobacco use (OR=1.34, 1.48), inflammatory arthritis (OR=1.61, 1.60), chronic kidney disease (OR=1.65, 1.14), hemodialysis (OR=1.93, 1.36), depression (OR=2.02, 1.73), and a hypercoagulable disorder (OR=2.76, 1.58). CONCLUSION The present study identified numerous patient-related risk factors independently associated with an increased risk of infection following knee arthroscopy in PP and Medicare-aged patients.

Abstract
OBJECTIVE To determine the clinical characteristics of Budd-Chiari syndrome (BCS), its causes and outcome at a tertiary care hospital. STUDY DESIGN An observational study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital,Karachi, from 2004 to 2014. METHODOLOGY Aretrospective analysis of data was conducted. Apredesigned questionnaire was filled from medical records of patients with BCS. Clinical features, etiology, management and outcome was noted from 2004 to 2014. Descriptive statistics were determined. RESULTS Forty-five patients' charts were reviewed; 26 (57.8%) were male patients. The median (IQR) age at diagnosis was 26.0 (20.5 to 34.5) years. Primary BCS was seen in 27 (60.0%) patients. The most frequent clinical features included ascites (82.2%), abdominal pain (55.6%), and hepatomegaly (31.1%). Acombined hepatic vein/inferior vena cava block was found in 25 (55.6%) patients. Out of the 28 tested patients protein C and protein S deficiencies were detected in 22 (78.6%) and 17 (60.7%) patients, respectively. Antithrombin III deficiency was detected in 14 (58.3%) of those tested patients. Anticoagulants were used in 24 (53.3%) patients. TIPS was done in 11 (24.4%) patients. Mortality was 6.7% (n=3). CONCLUSION Congenital thrombophilia was a major causal factor. Age, clinical features, biochemistry and management are important factors in survival.

Abstract
Inherited thrombophilia is a thrombotic diathesis caused by a variety of genetic abnormalities in anticoagulant factors such as antithrombin (AT), protein C (PC), and protein S (PS), or coagulation factors such as prothrombin and factor V. Patients with inherited thrombophilia often present with unusual clinical episodes of venous thromboembolism (VTE), which manifests as deep vein thrombosis or pulmonary thromboembolism in young persons (younger than 40 years), often with a positive family history of thrombosis. Moreover, the thrombosis sometimes recurs, despite anticoagulant therapy. The genetic background is known to differ between Caucasians and East Asians. Starting this April, inherited thrombophilia, AT, PC, or PS deficiency, are officially designated as intractable diseases, and the treatment of these diseases is subsidized as public expense.

Abstract
OBJECTIVES To compare peri-partal parameters between two groups of pregnant women - with and without gestational diabetes mellitus (GDM), to correlate degree of glucose abnormality with incidence of peri-partal morbidity and, finally, to analyse the potential effect of comorbidities (i.e. obesity, hypertension, thyreopathy, polycystic ovary syndrome, trombophylia, anemia, allergy, smoking) on pregnancy outcomes. DESIGN Epidemiological observational "case-control" study. SETTING Department of Obstetric and Gynaecology, Faculty Hospital Brno; Department of Internal Medicine, Diabetes Centre, Faculty Hospital Brno; Department of Pathophysiology, Faculty of Medicine, Masaryk University, Brno. METHODS The study comprised 432 pregnant women (364 with GDM diagnosis, 68 healthy controls) followed during a period 2011-2013. GDM was diagnosed by oral glucose tolerance test in 24-28th week of gestation (by fasting plasma glucose >5,6 mmol/l or >8,8 mmol/l in 60th min or >7,8 mmol/l in 120th min post-75g glucose load). Following peri-partal parameters were studied: ultrasonographic examination before delivery, a date of delivery, length of childbirth, induction, perinatal complications, post-delivery complications, section, abnormity in pH, base excess, Apgar score, birth weight. RESULTS Subjects with GDM had significantly increased rate of labour induction compared to healthy controls (P = 0.0035, chi-square test). Subgroup of GDM women classified as having a higher risk for adverse perinatal outcomes by a definition of Czech Obstetric and Gynaecology Society had significantly more labour inductions, more sections and instrumental deliveries. New-borns of those mothers had significantly more common worse perinatal outcomes (Apgar score and macrosomia). CONCLUSION Based on our data risk stratification of GDM subjects according to Czech Obstetric and Gynaecology Society appears relevant and justified.

Abstract
AIM The aim of this research was to have a thorough study of predictors of critical states during pregnancy after assisted reproductive technologies. MATERIALS AND METHODS A retrospective study of 303 patients with "near-miss," out of which 37 are pregnancy cases after ART (the main group) and 265 are spontaneous pregnancy cases (the control group). RESULTS Pregnancy after ART constituted 12.3% of all critical states. In the main group (10.8%), severe ovarian hyperstimulation prevailed over all possible reasons for critical states within the period of up to 22 weeks of gestation, whereas bleeding predominated in the control group (57.1%). When pregnancy terms exceeded 22 weeks, the leading reason for "near-miss" in the main group was preeclampsia (59.5%) with underlying thrombophilia (29.7%) and gestation pancreatic diabetes (32.4%); bleeding was the main factor in the control group (36.6%). CONCLUSION Women after assisted reproductive technologies constitute a high-risk group for critical obstetric states not only in the nearest time period but also long after ART.

Abstract
The objective of this study was to characterize risk factors for thrombotic events in lupus patients. A total of 272 lupus patients were followed up for five years during which the presence of aPL antibodies [anticardiolipin (aCL), anti-beta2-glycoprotein I (aβ2GPI) and lupus anticoagulant (LAC)] were determined, and all thrombotic incidents and antithrombotic therapy-related data were collected. At baseline, three groups were constituted, an aPL–group with 107 aPL negative patients, an aPL+ group with 81 aPL positive patients without clinical thrombosis and a secondary antiphospholipid syndrome (APS) group with 84 aPL+ patients who met the Sapporo criteria. LAC was more common in the APS than the aPL+ group (32.1% versus 9.9%, P < 0.001). The prevalence of clinical thrombotic events was significantly higher when all three types of aPL were present compared to only aCL positive cases. During follow up, aPL appeared in 7.5% of the aPL - group, and 2.8% of this group had thrombotic complications. In the aPL + group, thrombotic events reoccurred in 1.9% of those receiving antithrombotic prophylaxis and 6.9% of those without primary prophylaxis. Despite anticoagulant therapy, thrombotic events reoccurred in 8.3% of the APS group. These findings indicate that LAC, constant and cumulative presence of aPL and previous thrombosis are positive predictors for the development of thrombotic complication in lupus patients.

Abstract
We describe a 58-year old female patient with rapid development of arterial and venous thromboembolisms, including deep vein thrombosis (DVT) in the lower limbs, recurrent cerebral infarctions and bilateral pulmonary emboli. Her laboratory data on admission showed positive anticardiolipin antibody of IgG isotype (IgG aCL) and positive anti-β2 glycoprotein-I antibody of IgG isotype (IgG aβ2-GPI), and decreased protein C activity and protein S antigen. Systemic examinations revealed the presence of an ovarian cancer. Surgical resection was attempted, but her cancer infiltrated the pelvic wall and could not be resected. Despite treatment with unfractionated heparin followed by warfarin, she died due to recurrent episodes of cerebral infarction. This case was considered as probable catastrophic antiphospholipid syndrome (CAPS), which might be associated with ovarian cancer. Known as Trousseau's syndrome, arterial and, more commonly, venous thrombosis is a frequent complication of cancer and sometimes a harbinger of occult cancer. Our case indicates that there is an overlap between antiphospholipid syndrome (APS) and Trousseau's syndrome. It is important to bear in mind that a thrombotic event associated with cancer can be the first manifestation of CAPS.

Abstract
In case of unprovoked venous thromboembolism (VTE), the screening of thrombophilia is recommended whatever the age of the patient and the type of risk factors (RF). This prospective study was conducted in patients with unprovoked VTE to detect some predictive factors to have a higher risk of thrombophilia, focusing on age, history of venous thromboembolism, and the existence of a triggering event. From July 2000 to July 2002, in an Internal Medicine Department, unrelated patients with unprovoked VTE were included. Those unprovoked thromboembolic events were defined by the absence of association between permanent and transient RF. The primary outcome measure was the positivity of the thrombophilia screening for any type of abnormality detected (deficit of protein C, S, antithrombin, presence of a lupus anticoagulant, research of V and II mutations). Seventy-four patients were included. Eight died during the follow-up. A higher risk of thrombophilia was found in patients younger than 40 (p=0.03), or with a family but not personal history of VTE (p=0.01) or with transient RF (p=0.02). The most frequent abnormality of coagulation found in patients younger than 40 was the presence of a lupus anticoagulant. As a new strategy for the screening of thrombophilia, one could propose the following attitude: only patients with transient RF or family history of VTE could undergo a complete screening; for all the remaining patients who are younger than 40, a research of a lupus anticoagulant would be only performed. This strategy should now be balanced against the currently recommended systematic attitude in further studies.

Abstract
The findings of a large prospective study designed to identify primary and/or secondary hemostatic disorders before surgical interventions are presented. A total of 5649 unselected adult patients were enrolled to identify impaired hemostasis before surgical interventions. Each patient was asked to answer a standardized questionnaire concerning bleeding history. Activated partial thromboplastin time (aPTT), prothrombin time (PT), and platelet counts (PC) including PFA-100 (platelet function analyzer): collagen-epinephrine (C/E), and collagen-ADP (C/ADP) were routinely done in all patients. Additional tests, bleeding time (BT), and von Willebrand factor (vWF: Ag) were performed only in patients with a positive bleeding history and/or evidence of impaired hemostasis; e.g., drug ingestion. The bleeding history was negative in 5021 patients (88.8%) but positive in the remaining 628 (11.2%). Impaired hemostasis could be verified only in 256 (40.8%) of these patients. The vast majority were identified with PFA-100: C/E (n=250; 97.7%). The other six patients with impaired hemostasis were identifiable solely based on the PT (n=2), PFA-100: C/ADP (n=2), and vWF: Ag (n=2). The PFA-100: C/ADP detected 199 patients (77.7%). The only abnormality found among patients with a negative bleeding history was a prolonged aPTT due to lupus anticoagulant in nine patients (0.2%). The sensitivity of the PFA-100: collagen-epinephrine was the highest (90.8%) in comparison to the other screening tests (BT, aPTT, PT, vWF: Ag). The positive predictive value of the PFA-100: collagen-epinephrine was high (81.8%), but the negative predictive value was higher (93.4%). The use of a standardized questionnaire and, if indicated, the PFA-100: C/E and/or other specific tests not only ensure the detection of impaired hemostasis in almost every case but also a significant reduction of the cost.

Abstract
Objectives: We investigated the presence of congenital thrombophilic risk factors in a population of consecutive Italian patients affected by idiopathic sudden sensorineural hearing loss (SSNHL). Methods: We investigated 48 patients with idiopathic SSNHL for the presence of congenital thrombophilic risk factors. The factor V Leiden G1691A, the prothrombin G20210A allele, and methylenetetrahydrofolate reductase (MTHFR) C677T genotypes were investigated. Allele frequencies and genotype distribution of all factors found in patients were compared to those of 48 healthy subjects of the same ethnic background by χ2 and odds-ratio analysis. Odds ratios and 95% confidence intervals were calculated for allele and genotype frequencies of all thrombophilia variants. Statistical significance was accepted with a p value of less than .05. We also performed the following blood tests: hemacytometric analysis including platelet count, prothrombin time, activated partial thromboplastin time, fibrinogen, erythrocyte sedimentation rate, C-reactive protein, protein S, protein C, antithrombin III, and activated protein C resistance. Results: In our series, we did not find an association between SSNHL and abnormal levels of antithrombin III, protein C, protein S, D-dimer, or fibrinogen; activated protein C resistance; or factor V G1691 A, prothrombin G20210A, or MTHFR C677T mutations. Conclusions: At present, the few studies regarding genetic polymorphisms of congenital thrombophilic factors in SSNHL are not conclusive. According to our data, factor V G1691A, prothrombin G20210A, and MTHFR C677T variants should be not considered risk factors for SSNHL. Further large prospective studies are needed to provide currently lacking information and to improve our knowledge in the field before we recommend the determination of genetic polymorphism in SSNHL as routine practice.

Abstract
BACKGROUND The role of a hypercoagulable state in the pathogenesis of retinal vein occlusion (RVO) has not been conclusively established. AIM To analyse the prevalence of thrombophilia in RVO. DESIGN Prospective case-control study. METHODS All the patients diagnosed with RVO were referred to an Internal Medicine clinic and compared with sex- and age-matched individuals from a population-based cohort. Demographic, clinical and laboratory variables (including a thrombophilia panel) were analysed. RESULTS One hundred and seventy patients (93 men and 77 women; 68 ± 11 years) and 170 controls (80 men and 90 women; 67 ± 10 years) were included. RVO was peripheral in 113 cases. Genetic thrombophilia was detected in 13% of patients. Acquired thrombophilia was observed in 10% of cases and 4.7 % of controls (P < 0.01). Sixty-three percent of cases and 24.6% of controls had serum hyperhomocysteinemia (odds ratio [OR] 5.2, IC 95% 2.7-10.1; P < 0.0001) : In RVO patients aged <50 years (n = 11), 36.4% had genetic thrombophilia (P = 0.04), as well as 50% of those without vascular risk factors (n = 18; P = 0.01). Forty-one (24%) patients with RVO received antiplatelet agents and 13 (7.6%) were on anticoagulants due to preexistent atrial fibrillation. CONCLUSIONS We suggest that, in patients with RVO, hyperhomocysteinemia and antiphospholipid syndrome should be ruled out. Moreover, a study of genetic thrombophilia should only be considered in those aged <50 years or without cardiovascular risk factors. Antiplatelet therapy with aspirin is probably the treatment of choice of RVO, to reduce the overall vascular risk. Anticoagulation should only be considered in patients with high-risk thrombophilia.
