Angiogenesis is an essential process for proper functioning of the female reproductive system and for successful pregnancy realization. The multitude of factors required for physiological angiogenesis and the complexity of regulation of their temporal-spatial activities contribute to aberrations in human fertilization and pregnancy outcomes. In this study, we reviewed the current knowledge of the temporal expression patterns, functions, and regulatory mechanisms of angiogenic factors during foliculogenesis, early implantation/placentation and embryo development, as well as recurrent spontaneous abortions...

Aims: Closed-loop stimulation (CLS) seemed promising in preventing the recurrence of vasovagal syncope (VVS) in patients with a cardioinhibitory response to head-up tilt test (HUTT) compared with conventional pacing. We hypothesized that the better results of this algorithm are due to its quick reaction in high-rate pacing delivered in the early phase of vasovagal reflex, which increase the cardiac output and the blood pressure preventing loss of consciousness. Methods and results: This prospective, randomized, single-blind, multicentre study was designed as an intra-patient comparison and enrolled 30 patients (age 62...

Various studies have investigated the risk of recurrent spontaneous abortion (RSA) with plasminogen activator inhibitor-1 ( PAI-1) 4G/5G polymorphism. However, the results have been somewhat contradictory. Therefore, an updated meta-analysis based on 31 studies (5617 cases and 3952 controls) was undertaken to clarify this relationship. The degree of RSA risk was estimated using the odds ratio (OR) and the 95% confidence interval (CI). Overall, the random effects OR was 1.464 (95% CI: 1.269-1.690) for 4G versus 5G, 2...

Clinical pregnancies increasingly end in recurrent miscarriage (RM) during the first trimester, with genetic factors shouldering the main responsibility. MicroRNAs (miRNAs) regulate gene expression in a wide array of important biological processes. We examined the potential role of dysregulated miRNAs in RM pathogenesis and trophoblast development as an approach to elucidate the molecular mechanism behind RM. miRNA profiles from clinical specimens of RM and induced abortion (IA) were compared, and several miRNAs were found to be aberrantly expressed in RM samples...

STUDY QUESTION: Do extravillous trophoblasts (EVTs) invade non-arterial decidual vessels in healthy and pathological pregnancies? SUMMARY ANSWER: Our results reveal that trophoblast invasion of venous and lymphatic vessels is a frequent event during the first trimester of pregnancy and is compromised in  recurrent spontaneous abortion (RSA). In addition, the present data suggest that EVTs populate regional lymph nodes during pregnancy. WHAT IS ALREADY KNOWN: Human trophoblasts remodel and invade decidual spiral arteries...

Acute signs associated with cardiovascular disease occurred in three pregnant okapi ( Okapia johnstoni ) during early to midgestation and progressed to congestive heart failure. Congestive heart failure was diagnosed antemortem using echocardiography and plasma cardiac troponin levels. Clinical signs included decreased activity, hyporexia, tachypnea, dyspnea, flared nostrils, and productive coughing with copious amounts of foamy nasal discharge. Parenteral and oral treatment with furosemide, enalapril, and spironolactone controlled clinical signs in the three okapi allowing each to carry out one pregnancy to term...

PROBLEM: In this study, we aim to investigate if the expression of TWIST in the first-trimester placenta and decidua has any association with spontaneous abortion (SAB) and recurrent pregnancy losses (RPL). METHODS: Expression of TWIST was measured in the first-trimester trophoblast and decidual tissues using RT-PCR and immunohistochemistry. Women with a pregnancy loss comprised the study group (AB group) including women with two or more recurrent pregnancy loses (RPL group), and women with a spontaneous abortion who had no history of previous pregnancy losses (SAB group)...

Recurrent spontaneous abortion (RSA) is defined as 3 or more consecutive pregnancy failures. Thrombin-activatable fibrinolysis inhibitor (TAFI) is a plasma zymogen that regulates both fibrinolysis and inflammation. The TAFI 1040C/T polymorphism could alter the circulating levels of TAFI with a reduced capacity to remove the fibrin clots from the circulation; therefore, it could be considered a molecular risk factor for RSA. The TAFI 1040C/T polymorphism was studied in 50 patients with RSA by polymerase chain reaction-restriction fragment length polymorphism technique and compared to 50 age- and gender-matched healthy volunteers as a control group to verify its possible association with RSA...

PURPOSE: Dendritic cells (DCs) are involved in immune system, which can also regulate the differentiation of T helper 17 (Th17) and regulatory T cells (Treg). DCs and Th17/Treg participate in preeclampsia and recurrent spontaneous abortion (RSA), but there is still lack of research in intrahepatic cholestasis of pregnancy (ICP). The aim was to evaluate the expression and significance of CD83(+)DCs, CD1a(+)DCs, interleukin-17 (IL-17) and IL-35 in serum and placental tissues of patients with ICP...

Antiphospholipid antibodies (APLAbs) are generally considered as risk factors for foetal death, for premature birth ≤34weeks due to severe pre-eclampsia or severe placental insufficiency and for recurrent consecutive spontaneous abortions <10weeks. Among these three obstetrical morbidities, only the first one is however not regularly questioned. The coexistence of an inflammatory disease and/or of thrombotic manifestations increases the obstetrical risks. Among the three criteria APLAbs, i.e. lupus anticoagulant (LA), anticardiolipin (aCL) Abs, anti-β2 glycoprotein-I (aβ2GP1)Abs, LA seems the more widely associated to clinical risks, the clinical impact of aβ2GP1Abs is progressively defined and the pejorative impact of triple positivity is still discussed...

Importance: Adults late after total correction of tetralogy of Fallot (TOF) are at risk for major complications. Cardiovascular magnetic resonance (CMR) imaging is recommended to quantify right ventricular (RV) and left ventricular (LV) function. However, a commonly used risk model by Khairy et al requires invasive investigations and lacks CMR imaging to identify high-risk patients. Objective: To implement CMR imaging in noninvasive risk stratification to predict major adverse clinical outcomes...

A woman aged 35 years was diagnosed with triple-negative breast cancer in October 2012. During the investigation, it was discovered that she was pregnant, the patient decided to have an abortion. She was submitted to a radical modified mastectomy and adjuvant chemotherapy followed by adjuvant breast radiotherapy of the left breast. 2 months after the adjuvant treatment, she began to have headaches and dizziness. The cranial MRI (head MRI) showed brain metastasis. She was then treated with whole brain radiotherapy, stereotactic radiosurgery and concomitant temozolomide which resulted in complete response...

Takayasu arteritis (TA) is a chronic, progressive, autoimmune, idiopathic, and large-vessel vasculitis that usually affects young adults, especially females. TA primarily affects the aorta and its major branches, the coronary arteries, and the pulmonary arteries. Recurrent pregnancy loss is usually defined as three or more consecutive losses occurring at <20 weeks' gestation of a clinically recognized pregnancy. Common causes of recurrent fetal loss include anatomic, chromosomal, hormonal, infectious, or antiphospholipid antibody syndrome...
