We analyzed a cohort of 36 females with pregnancy loss. In addition to 11 patients with antiphospholipid antibody syndrome and 2 patients with congenital antithrombin (AT) or protein C deficiency, we identified 5 patients with low fibrinogen levels (median 110 mg/dL) prior to 10 weeks of gestation. Four of these 5 patients underwent a fibrinogen gene analysis, and all 4 were found to be heterozygotes for the α-fibrinogen (FGA) Thr321Ala polymorphism. One female without hypofibrinogenemia with a history of 8 pregnancy losses was found to be homozygous for the same polymorphism, and she also showed hypercoagulability without thrombosis. In conclusion, there was a relatively high frequency of pregnancy loss in the setting of hypofibrinogenemia and/or the FGA Thr312Ala polymorphism, and this may be an important risk factor for pregnancy loss and a hypercoagulable state in later pregnancy.

Abstract Thromboembolic disease is common with an annual incidence of 1–3/1000 individuals. Both acquired and genetic risk factors are responsible. A risk factor for thrombosis can now be identified in over 80 percent of patients. Fifty percent of thrombotic events in patients with inherited thrombophilia are associated with an acquired risk factor. Patients with multiple inherited risk factors are at a greater risk. Two common variations of the MTHFR gene (677CàT and 1298AàC) result in amino acid substitutions and enhanced thermolability of the enzyme. The latter, in the presence of folic acid deficiency, results in elevated homocysteine levels. Thrombosis has been observed in these patients, but there is still controversy whether there is a direct association (Bezemer I, et al. Arch Int Med167, 497–501, 2007; den Heijer M et al. J Thromb Haemost3:292–299, 2005). In the present study, we describe the spectrum of thromboembolic disease observed in 39 patients with a variety of MTHFR polymorphisms referred to a specialty center with a personal or family history of thromboses or obstetrical loss, 18 of these patients having no other risk factor other than MTHFR polymorphisms. These polymorphisms include 18 heterozygotes (11 with 677CàT; 7 with 1298AàC), 9 homozygotes (5 with 677CàT; 4 with 1298AàC) and 12 compound heterozygotes (677CàT and 1298AàC). Concomitant risk factors were found in twenty-one patients (factor V Leiden - 6; prothrombin G20210A - 3; protein C deficiency - 1; protein S deficiency - 1; PAI-1 polymorphism - 2; activated protein C resistance - 2; antiphospholipid antibody syndrome - 5; malignancy - 3; coronary artery disease - 1; hemolytic anemia - 1; factor VIII deficiency - 1). Types of thromboembolic manifestations observed in the 39 patients include venous thromboembolism (22), obstetrical loss (7), arterial thrombosis (3), myocardial infarction (3), ischemic CNS lesions (2), and palpable purpura (1), for a total of 38 manifestations. Seven of the patients had a family history of thromboembolic disease. Patients with only MTHFR polymorphisms suffered 16 types of thromboembolic events (16/38=42%). Our observations suggest that MTHFR polymorphisms alone do play a role in clinically relevant thrombotic disease and probably increase the incidence of these diseases in patients harboring other causes of thrombophilia. Therefore, continuing surveillance for this polymorphism as part of a clinical thrombophilia assessment is recommended, particularly if homocysteine levels are elevated.

SummaryThe risk of thrombosis in women increases significantly during treatment with hormonal therapy (HT). The aim of this study was to evaluate ProC Global assay in women with a history of venous thromboembolism (VTE) while using HT. Protein C activation time normalized ratio (PCAT-NR) levels were significantly lower in 32 women with a history ofVTE while using HT (0.72 ± 0.1) compared with 56 healthy controls without HT, matched by age at blood sampling (0.99 ± 0.2) and 40 healthy controls with HT, matched by age and HT at VTE event (0.94 ± 0.2) (P<0.001 for both). PCAT-NR lower than the cut-off level of 0.8 was found in 23/32 (72%) patients compared with 5/56 (9%) age-matched controls (OR=26, 95%CI: 7-106, P<0.001) and 9/40 (22.5%) of HT-matched controls (OR=9, 95%CI: 2.7-30, P<0.001). Any thrombophilic risk factor was found in 20/32 (62.5%) of patients compared with 12/56 (21.4%) of agematched controls (OR=6, 95%CI: 2.1-10, P<0.001) and 12/40 (30%) of HT-matched controls (OR=4, 95%CI: 1.3-11.8, P=0.006).Out of the variables that are risk factors of VTE as age, HT or thrombophilic risk factor, ProC Global assay was found in the multivariate analysis - logistic regression, as the parameter that was the most associated with patient group [Exp(B)=15.8, 95% CI: 4.2-59.0, P<0.001]. In conclusion, abnormal PCAT-NR is associated with VTE in women using HT. ProC Global assay may potentially serve asa diagnostic tool for evaluating the risk of VTE in women prior to administration of HT.

Abstract BackgroundThis study aimed to investigate the background of patients who presented with pulmonary embolism (PE) on contrast-enhanced chest computed tomography (CT) and to explore the risk factors for PE.MethodsThis study included a review of the medical records of all 50,621 patients who were admitted to one community hospital between January 1, 2013 and December 31, 2017. Data on sex, age, risk factors related to blood flow stagnation (obesity, long-term bed rest, cardiopulmonary disease, cast fixation, long-term sitting), risk factors related to vascular endothelial disorder (surgery, trauma/fracture, central venous catheterization, catheter tests/treatments, vasculitis, antiphospholipid antibody syndrome, history of venous thromboembolism (VTE)), and risk factors related to hypercoagulability (malignant tumor, use of oral contraceptives/low-dose estrogen progestin/steroids, infection, inflammatory enteric disease, polycythemia, protein C or protein S deficiency, dehydration) were evaluated.ResultsOf all inpatients, 185 (0.37%) were diagnosed with PE after contrast-enhanced chest CT examination. The rate of discovering PE was significantly greater in women (0.48%, 93/19,409) than men (0.29%, 92/31,212) (P=0.0008). Of the 185 patients with PE, 173 (94%) had some type of risk factor. For both men and women, the most frequent risk factor was a malignant tumor, followed by infection and obesity for men and long-term bed rest and obesity for women. The most common malignant tumor was lung cancer. Of the 12 patients whose clear PE-inducing factor could not be identified, but there is possible involvement of antipsychotic agent.ConclusionsThe risk factors for PE were identified in this single-center, retrospective study.

Pregnancy loss, natural or induced, is linked to higher rates of mental health problems, but little is known about its effects during the postpartum period. This study identifies the percentages of women receiving at least one postpartum psychiatric treatment (PPT), defined as any psychiatric treatment (ICD-9 290-316) within six months of their first live birth, relative to their history of pregnancy loss, history of prior mental health treatments, age, and race. The population consists of young women eligible for Medicaid in states that covered all reproductive services between 1999–2012. Of 1,939,078 Medicaid beneficiaries with a first live birth, 207,654 (10.7%) experienced at least one PPT, and 216,828 (11.2%) had at least one prior pregnancy loss. A history of prior mental health treatments (MHTs) was the strongest predictor of PPT, but a history of pregnancy loss is also another important risk factor. Overall, women with a prior pregnancy loss were 35% more likely to require a PPT. When the interactions of prior mental health and prior pregnancy loss are examined in greater detail, important effects of these combinations were revealed. About 58% of those whose first MHT was after a pregnancy loss required PPT. In addition, over 99% of women with a history of MHT one year prior to their first pregnancy loss required PPT after their first live births. These findings reveal that pregnancy loss (natural or induced) is a risk factor for PPT, and that the timing of events and the time span for considering prior mental health in research on pregnancy loss can significantly change observed effects. Clinicians should screen for a convergence of a history of MHT and prior pregnancy loss when evaluating pregnant women, in order to make appropriate referrals for counseling.

Background: The real incidence of Kawasaki disease (KD) in the Maghreb countries (Morocco, Algeria, and Tunisia) is unknown. It is estimated low according to the literature. However, the number of Maghrebi children living in Quebec (Qc) affected by KD seems important. We sought to determine the incidence of KD among Maghrebi children in Qc, Canada, and to study its epidemiological and clinical features and to clarify possible risk factors related or superimposed to their immigration. Methods: A retrospective study of KD in Maghrebi children living in Qc (n=24) (1996-2013), compared to reports from Fes, Morocco (n=23) a doctoral thesis published in 2010 (2001-2009) and from Tunisia (n=31) collected in five university hospitals with four from the Great Tunis and one from Nabeul city (1996-2013). There are no reports available from Algeria. The “country of origin” specific population in the Province of Qc was obtained from Statistics Canada. Results: The annualized incidence rate (AIR) of KD among Maghrebi children in Qc was 9.58/100,000 children under 5 years(Standard-Denominator (SD)).This is 6 times higher in Qc (5.57/SD and 19.02/SD among Tunisian and Moroccan descents) vs Tunisia (Nabeul Governorate) and Morocco (Fes) (0.95/SD and 3.15/SD). Personal and family history of allergy were significantly higher in Qc 42% (10/24) and 75% (18/24), respectively, whereas these features were reported near 0% in both reports from Morocco and Tunisia. The prevalence of incomplete KD criteria was relatively high in the 3 series 46% (11/24) in Qc vs 43% (10/23) and 35% (11/31); (p=NS). Diagnosis was late (gt day 10 of fever) in 1/24(4%) in Qc vs 7/23 (30%) in Morocco and 11/31 (35%) in Tunisia; (p 0.01). IVIG were administered in the acute phase to all patients in Qc, 5/23 in Morocco and 28/31 in Tunisia. However coronary complications were more common in Qc 42% (10/24) vs 22% (5/23) vs 19% (6/31) (p=0.02). Aneurysms were significantly associated with the incomplete form in the 3 groups (p=0.01). Conclusions: The observed AIR of KD in the Maghreb community in Qc is higher than the countries of origin where underdiagnosis is possible. Atopy may still be a risk factor in Qc. The coronary artery disease seems linked not only to therapeutic delay but also to the underlying terrain.

Dengue is a mosquito-borne virus that causes an influenza-like illness ranging in severity from asymptomatic to fatal. Dengue in pregnancy has been associated with adverse outcomes including miscarriage, preterm birth and fetal and neonatal death. We present the case of a multiparous woman who presented at 9 weeks’ gestation with vaginal bleeding and abdominal cramping after a 1 month stay in Mexico. She was initially diagnosed with miscarriage with plan for outpatient follow-up. She was readmitted 3 days later with fever, retro-orbital pain, arthralgia, rash, pancytopenia and transaminitis and managed with intravenous fluids and acetaminophen. Of note, dengue serology was initially negative but retesting 2 days later was positive. It is imperative that clinicians have heightened suspicion for dengue in pregnant women with history of travel to or residence in a dengue-endemic area and consistent clinical evidence.

Introduction: The AHA notes that more than 76% of strokes are the first occurrence. There are class 1 recommendations for the management of common risk factors such as atrial fibrillation (AF), hyperlipidemia (HLD), hypertension (HTN), diabetes (DM), and vascular disease. The purpose of this study is to investigate the percentage of large vessel strokes that are potentially preventable with adequate management of vascular risk factors. Methods: A retrospective chart review was conducted on all patients undergoing endovascular therapy (EVT) from 2012-2019. Data was collected on vascular risk factors present prior to admission including HTN, DM, HLD, AF, and smoking. Preventable stroke was defined as having at least one of the following: untreated AF, untreated HLD, poorly controlled HTN (presence of left ventricular hypertrophy on transthoracic echo), history of vascular disease not on an antiplatelet agent, poorly controlled DM (A1c>10), current smoking. Groups were compared based on age, sex and 90 day functional outcomes, with favorable outcome defined as mRS ≤ 2. Results: Our sample included 396 patients who underwent EVT (mean age 65, 50% female). 42% of patients with Afib were not on anticoagulation, 31% of patients with HLD were untreated, 39% of patients with HTN were poorly controlled, 27% of patients with a history of vascular disease were not on an antiplatelet, 14% of patients with DM were poorly controlled, and 46% of all patients were smokers. In total, 78% of patients had at least 1 poorly controlled risk factor and 37% had at least 2. There was no difference in rates of preventable stroke between males and females (48% vs 52%, p=0.30) and between age groups above and below 70 (40% vs 60%, p=0.68). 64% of patients with well controlled risk factors had a favorable outcome compared to 51% with at least one poorly controlled risk factor (p=0.03). Conclusions: Our data suggests that despite guidelines on management of vascular risk factors, a large number of these are poorly controlled prior to admission for large vessel stroke, leading to a potentially preventable procedure. Not only could improved primary prevention save the wide array of resources utilized in EVT, but it could also influence long term outcomes in this cohort of patients.

A 25-year-old Bangladeshi lady presented to neurology with a three-month history of involuntary movements of her right arm, associated with loss of power. There was progression to the right leg, and she subsequently developed episodes of slurred speech and blurred vision. At the time of presentation, she was 12 weeks pregnant and the symptoms were reported to have started at conception. Past medical history was unremarkable apart from one first trimester miscarriage and there was no significant family history suggestive of a hereditary neurological condition. MRI of the head revealed no abnormalities but serology showed positive antinuclear antibodies (ANAs) at a titre of 1/400. Further investigations revealed strongly positive anticardiolipin antibodies (>120) and positive lupus anticoagulant antibodies. The patient had a second miscarriage at 19 weeks gestation strengthening the possibility that the chorea was related to antiphospholipid antibody syndrome and she was started on a reducing dose of Prednisolone 40 mg daily and aspirin 300 mg daily. Six months later, she had complete resolution of neurological symptoms. There are several reports of chorea as a feature of antiphospholipid syndrome, but no clear consensus on underlying pathophysiology.
