Abstract
Hemophilia is a rare bleeding disorder caused by a genetic defect on chromosome X. It is inherited as an X-linked trait, and hence, it is more frequently diagnosed in males, whereas women have been traditionally considered only as carriers of the disease. However, the role of women in families of patients with hemophilia is pivotal. As mothers, sisters, daughters, and female partners of patients with hemophilia, they play a central role in the management of the patient, considering healthcare, social, and familial aspects, but they might be affected by the disease as well, particularly in regions where consanguinity is frequent. This paper aims to explore the involvement of women in hemophilia, including their carrier status, bleeding symptoms, treatment challenges, and psychosocial impact not only related to male patients, but also as patients affected with hemophilia themselves. We advocate health equity, equal access to healthcare for men and women with hemophilia and dedicated resources to improve the unique needs of the women dealing with hemophilia, ultimately leading to improved care and quality of life.

Abstract
INTRODUCTION Haemophilia carriers (HCs) face a multitude of psychological challenges, mainly linked to the possibility of having an affected child. Important reproductive decisions such as opting for pre-implantation genetic testing, or choosing prenatal diagnosis and then whether to continue or interrupt pregnancy in case of affected male fetus, have to be taken into consideration. Notwithstanding, the role of psychological characteristics on such decision-making process needs further investigation. AIM The aim of this study was to investigate whether HCs' beliefs and emotions about haemophilia and cognitive factors such as decision-making style, risk perception, coping strategies in response to stress, and need for cognitive closure might modulate HCs' reproductive decisions. METHODS Participants were interviewed about their beliefs and emotions on haemophilia and filled an on-line standardized questionnaire on cognitive variables. Sixty HCs participated in this study. RESULTS Results show that HCs with high distress for haemophilia given by negative childhood experiences for one or more family member illness and by high concern for their children's health, and with psychological traits characterized by logical (versus emotional) reasoning, active coping style and high need for certainty, tend to choose diagnostic prenatal tests over routine pregnancy analysis. CONCLUSION This study highlighted the influence of negative early-life experience with haemophilia and of several cognitive factors in HCs choice of prenatal test.

Abstract
AbstractHemostasis is a dynamic process that starts in utero. Neonates, especially those who are born preterm, are at high risk of bleeding. The coagulation system evolves with age, and the decreased levels of coagulation factors along with hypo-reactive platelets are counterbalanced with increased activity of von Willebrand factor, high hematocrit and mean corpuscular volume as well as low levels of coagulation inhibitors that promote hemostasis. Neonates with congenital bleeding disorders such as hemophilia are at even higher risk of bleeding complications. This review will focus upon one of the most devastating complications associated with neonatal bleeding: intracranial hemorrhages (ICH). While etiology may be multifactorial and impacted by maternal as well as fetal risk factors, the mode of delivery certainly plays an important role in the pathogenesis of ICH. We will address prematurity and congenital bleeding disorders such as hemophilia A and B and other rare bleeding disorders as risk factors and present an updated approach for treatment and possible prevention.

Abstract
OBJECTIVE Carrier couples of recessive diseases face an important decision-making process regarding their familial planning that can become a significant source of discomfort and potential regrets. To date, no study has described the decisional needs of carrier couples of Leigh syndrome French-Canadian type, hereditary tyrosinemia type 1, hereditary motor and sensory neuropathy with or without agenesis of the corpus callosum and autosomal recessive spastic ataxia of Charlevoix-Saguenay undergoing family planning decision-making process. Our study aimed to describe the decisional needs of carrier couples according to the Ottawa Decision Support Framework. METHODS A qualitative descriptive study was conducted. Qualitative individual and joint couple interviews were performed among 39 carrier individuals and 11 health and social care professionals. RESULTS Carrier couples' decision-making process is complex, and their decisional needs include, among others, sufficient knowledge about the disease and the reproductive options, personal values and available support. Increased decisional conflict was observed among carriers of diseases associated with low morbidity and mortality. CONCLUSION Family planning decision-making is an evolutive deliberative process that requires appropriate shared decision-making to insure decisional comfort. PRACTICE IMPLICATIONS Carrier couples family planning decision-making process needs to be better supported.

Abstract
Hemophilia A (HA) and hemophilia B (HB) are rare disorders, being caused by the total lack or under-expression of two factors from the coagulation cascade coded by genes of the X chromosome. Thus, in hemophilic patients, the blood does not clot properly. This results in spontaneous bleeding episodes after an injury or surgical intervention. A patient-centered regimen is considered optimal. Age, pharmacokinetics, bleeding phenotype, joint status, adherence, physical activity, personal goals are all factors that should be considered when individualizing therapy. In the past 10 years, many innovations in the diagnostic and treatment options were presented as being either approved or in development, thus helping clinicians to improve the standard-of-care for patients with hemophilia. Recombinant factors still remain the standard of care in hemophilia, however they pose a challenge to treatment adherence because they have short half-life, which where the extended half-life (EHL) factors come with the solution, increasing the half-life to 96 hours. Gene therapies have a promising future with proven beneficial effects in clinical trials. We present and critically analyze in the current manuscript the pros and cons of all the major discoveries in the diagnosis and treatment of HA and HB, as well as identify key areas of hemophilia research where improvements are needed.

Abstract
INTRODUCTION Despite increasing awareness of issues faced by women and girls with inherited BDs (WGBD), standards of care are lacking, with disparities in diagnosis and treatment for WGBD across Europe. We aimed to develop practical principles of care (PoC) to promote standardization of care for WGBD within European Haemophilia Treatment and Comprehensive Care Centres (HTC/CCCs). METHODS The co-creation process, supported by the European Association for Haemophilia and Allied Disorders, consisted of four multidisciplinary meetings with health care providers (HCPs) experienced in WGBD care, and European Haemophilia Consortium representatives, combined with broad patient and HCP consultations in the European haemophilia community. Relevant medical societies outside Europe were contacted for confirmation. RESULTS We developed ten PoC for WGBD, stressing the importance and benefits of a centralized, multidisciplinary, comprehensive, family-centred approach to support and manage WGBD during all life stages. These PoC emphasise the right to equitable access and quality of care for all people with BDs, irrespective of gender. Multiple medical societies outside Europe also confirmed their support for endorsement. CONCLUSIONS Ten PoC for WGBD evolved from an iterative process among stakeholders, supported by relevant medical societies worldwide. These PoC can serve as a benchmark for diagnosis and comprehensive multidisciplinary management of WGBD, and improve awareness of their unique challenges. They offer a framework to guide HTC/CCCs in providing equitable care for all WGBD, both in their own services and in other healthcare settings. Implementation of these principles aims to positively impact the health, wellbeing and quality of life for WGBD.

Abstract
Reproductive genetic carrier screening identifies couples with an increased chance of having children with autosomal and X-linked recessive conditions. Initially only offered for single conditions to people with a high priori risk, carrier screening is becoming increasingly offered to individuals/couples in the general population for a wider range of genetic conditions. Despite advances in genomic testing technology and greater availability of carrier screening panels, there is no consensus around which types of conditions to include in carrier screening panels. This study sought to identify which types of conditions parents of children with a genetic condition believe should be included in carrier screening. Participants (n = 150) were recruited through Royal Children's Hospital (RCH) Melbourne outpatient clinics, the Genetic Support Network of Victoria (GSNV) and a databank of children with hearing loss (VicCHILD). This study found that the majority of participants support offering carrier screening for: neuromuscular conditions (n = 128/134, 95.5%), early fatal neurodegenerative conditions (n = 130/141, 92.2%), chronic multi-system disorders (n = 124/135, 91.9%), conditions which cause intellectual disability (n = 128/139, 92.1%) and treatable metabolic conditions (n = 120/138, 87.0%). Views towards the inclusion of non-syndromic hearing loss (n = 88/135, 65.2%) and preventable adult-onset conditions (n = 75/135, 55.6%) were more mixed. Most participants indicated that they would use reproductive options to avoid having a child with the more clinically severe conditions, but most would not do so for clinically milder conditions. A recurring association was observed between participants' views towards carrier screening and their lived experience of having a child with a genetic condition.

Abstract
Purpose of Review Prenatal stem cell and gene therapy approaches are amongst the few therapies that can promise the birth of a healthy infant with specific known genetic diseases. This review describes fetal immune cell signaling and its potential influence on donor cell engraftment, and summarizes mechanisms of central T cell tolerance to peripherally-acquired antigen in the context of prenatal therapies for Hemophilia A. Recent Findings During early gestation, different subsets of antigen presenting cells take up peripherally-acquired, non-inherited antigens and induce the deletion of antigen-reactive T-cell precursors in the thymus, demonstrating the potential for using prenatal cell and gene therapies to induce central tolerance to FVIII in the context of prenatal diagnosis/therapy of Hemophilia A. Summary Prenatal cell and gene therapies are promising approaches to treat several genetic disorders including Hemophilia A and B. Understanding the mechanisms of how FVIII-specific tolerance is achieved during ontogeny could help develop novel therapies for HA and better approaches to overcome FVIII inhibitors.

Abstract
Background Genomic sequencing technologies have made the possibility of population screening for whole panels of genetic disorders more feasible than ever before. As one of the most common single gene disorders affecting the UK population, hemophilia is an attractive candidate to include on such screening panels. However, very little is known about views toward genetic screening amongst people with hemophilia or their family members, despite the potential for a wide range of impacts on them. Methods Twenty‐two in‐depth qualitative interviews were undertaken to explore the views of adults with hemophilia and their family members, recruited through the Haemophilia Society UK. These interviews were used to develop a survey, the Haemophilia Screening Survey (UK), which was distributed in paper and online format through the support group, receiving 327 returns between January and June 2018. Results Fifty‐seven per cent of the sample supported preconception carrier screening of the population for hemophilia, and 59% supported prenatal carrier screening. Key reasons for support included a desire to reduce pregnancy terminations and increase awareness of hemophilia. Despite support for screening however, 90% of the sample disagreed with pregnancy terminations for hemophilia. Conclusions Families and adults living with hemophilia are more supportive of screening for information and preparation purposes than to prevent boys with hemophilia from being born. A distinction was made between preventing the disease and preventing the lives of people with it, with support shown for the use of screening to achieve the former, but not at the expense of the latter.

Abstract
INTRODUCTION As genomic sequencing become more efficient and cost-effective, the number of conditions identified through newborn screening globally is set to dramatically increase. Haemophilia is a candidate condition; however, very little is known about the attitudes of the haemophilia community towards screening. AIM This study aimed to outline the perspectives of adults with haemophilia and their families towards newborn screening. METHODS A paper and online survey on screening were distributed to every family known to the Haemophilia Society UK. Data collection occurred between January and June 2018. In total, 327 participants completed the survey: 76% were a relative of a person with haemophilia and 24% had haemophilia themselves; 83% were living with haemophilia A and 17% with haemophilia B. RESULTS The vast majority supported newborn screening (77%) and preferred it to other forms of screening (preconception or prenatal). Participants supported newborn screening primarily because they viewed it as a means to facilitate early support and treatment, facilitate informed decisions about future pregnancies and prevent the "diagnostic odyssey." The 23% who did not support the screen did not associate these particular benefits with newborn screening. CONCLUSION Haemophilia emerged from this analysis as a condition that the vast majority of participants considered a "liveable" disability and one best suited to newborn screening programmes that could improve support to affected families rather than reduce the birth rate of affected children.

MOLECULAR THERAPY-METHODS & CLINICAL DEVELOPMENT 2016; 5:16020.

Abstract
Recent advances in high-throughput molecular testing have made it possible to diagnose most genetic disorders relatively early in gestation with minimal risk to the fetus. These advances should soon allow widespread prenatal screening for the majority of human genetic diseases, opening the door to the possibility of treatment/correction prior to birth. In addition to the obvious psychological and financial benefits of curing a disease in utero, and thereby enabling the birth of a healthy infant, there are multiple biological advantages unique to fetal development, which provide compelling rationale for performing potentially curative treatments, such as stem cell transplantation or gene therapy, prior to birth. Herein, we briefly review the fields of in utero transplantation (IUTx) and in utero gene therapy and discuss the biological hurdles that have thus far restricted success of IUTx to patients with immunodeficiencies. We then highlight several recent experimental breakthroughs in immunology, hematopoietic/marrow ontogeny, and in utero cell delivery, which have collectively provided means of overcoming these barriers, thus setting the stage for clinical application of these highly promising therapies in the near future.

Abstract
The past few decades have seen major advances in multidisciplinary obstetric care and management of gynecological conditions in women with bleeding disorders. Awareness of the impact of bleeding disorders has improved among the obstetric and gynecological community. Undiagnosed bleeding disorders can be the underlying cause for a significant proportion of women with heavy menstrual bleeding. They may also be the cause or a contributory factor for other gynecological problems, such as dysmenorrhea, intermenstrual bleeding, and endometriosis. Hemostatic assessment should be considered in women referred for menstrual abnormalities if they have a positive bleeding history as quantified by bleeding assessment tools. The reproductive choices and options for prenatal diagnosis are also expanding for families with hemophilia with a drive toward achieving a non-invasive approach. Current non-invasive prenatal diagnostic techniques are limited to identification of fetal gender. Research is ongoing to overcome the specific diagnostic challenges of identifying hemophilia mutations, utilizing free fetal DNA circulating in maternal plasma. The management of obstetric hemorrhage has recently evolved to include a greater focus on the identification of and early treatment for coagulation disorders. Deficiencies in certain hemostatic variables are associated with progression to more severe bleeding; therefore, specific interventions have been proposed to target this. Evidence is still lacking to support such strategy, and future research is required to assess the efficacy and the safety of these hemostatic interventions in women with persistent PPH.
