RESUMO

There is a need to close the gap between knowledge and action in health care. Effective care requires a convenient and reliable distribution process. As global internet and mobile communication increase capacity, innovative approaches to digital health education platforms and care delivery are feasible. We report the case of a young African woman who developed acute secondary amenorrhea at age 18. Subsequently, she experienced a 10-year delay in the diagnosis of the underlying cause. A global digital medical hub focused on women's health and secondary amenorrhea could reduce the chance of such mismanagement. Such a hub would establish more efficient information integration and exchange processes to better serve patients, family caregivers, health care providers, and investigators. Here, we show proof of concept for a global digital medical hub for women's health. First, we describe the physiological control systems that govern the normal menstrual cycle, and review the pathophysiology and management of secondary amenorrhea. The symptom may lead to broad and profound health implications for the patient and extended family members. In specific situations, there may be significant morbidity related to estradiol deficiency: (1) reduced bone mineral density, 2) cardiovascular disease, and 3) cognitive decline. Using primary ovarian insufficiency (POI) as the paradigm condition, the Mary Elizabeth Conover Foundation has been able to address the specific global educational needs of these women. The Foundation did this by creating a professionally managed Facebook group specifically for these women. POI most commonly presents with secondary amenorrhea. Here we demonstrate the feasibility of conducting a natural history study on secondary amenorrhea with international reach to be coordinated by a global digital medical hub. Such an approach takes full advantage of internet and mobile device communication systems. We refer to this global digital women's health initiative as My 28 Days®.

RESUMO

CONTEXT: A genetic etiology likely accounts for the majority of unexplained primary ovarian insufficiency (POI). OBJECTIVE: We hypothesized that heterozygous rare variants and variants in enhanced categories are associated with POI. DESIGN: The study was an observational study. SETTING: Subjects were recruited at academic institutions. PATIENTS: Subjects from Boston (n = 98), the National Institutes of Health and Washington University (n = 98), Pittsburgh (n = 20), Italy (n = 43), and France (n = 32) were diagnosed with POI (amenorrhea with an elevated follicle-stimulating hormone level). Controls were recruited for health in old age or were from the 1000 Genomes Project (total n = 233). INTERVENTION: We performed whole exome sequencing (WES), and data were analyzed using a rare variant scoring method and a Bayes factor-based framework for identifying genes harboring pathogenic variants. We performed functional studies on identified genes that were not previously implicated in POI in a D. melanogaster model. MAIN OUTCOME: Genes with rare pathogenic variants and gene sets with increased burden of deleterious variants were identified. RESULTS: Candidate heterozygous variants were identified in known genes and genes with functional evidence. Gene sets with increased burden of deleterious alleles included the categories transcription and translation, DNA damage and repair, meiosis and cell division. Variants were found in novel genes from the enhanced categories. Functional evidence supported 7 new risk genes for POI (USP36, VCP, WDR33, PIWIL3, NPM2, LLGL1, and BOD1L1). CONCLUSIONS: Candidate causative variants were identified through WES in women with POI. Aggregating clinical data and genetic risk with a categorical approach may expand the genetic architecture of heterozygous rare gene variants causing risk for POI.

RESUMO

Primary ovarian insufficiency (POI) is a clinical spectrum of ovarian dysfunction. Overt POI presents with oligo/amenorrhea and hypergonadotropic hypogonadism before age 40 years. Overt POI involves chronic health problems to include increased morbidity and mortality related to estradiol deficiency and the associated osteoporosis and cardiovascular disease as well as psychological and psychiatric disorders related to the loss of reproductive hormones and infertility. Presently, with standard clinical testing, a mechanism for Overt POI can only be identified in about 10% of cases. Now discovery of new mechanisms permits an etiology to be identified in a research setting in 25-30% of overt cases. The most common genetic cause of Overt POI is premutation in FMR1. The associated infertility is life altering. Oocyte donation is effective, although many women prefer to conceive with their own ova. Surprisingly, the majority who have Overt POI still have detectable ovarian follicles (70%). The major mechanism of follicle dysfunction in Overt POI has been histologically defined by a prospective NIH study: inappropriate follicle luteinization due to the tonically elevated serum LH levels. A trial of physiologic hormone replacement therapy, clinically proven to suppress the elevated LH levels in these women, may improve follicle function and increase the chance of ovulation. Here, we report the case of a woman with Overt POI diagnosed at age 35 years. To attempt pregnancy, she elected a trial of intrauterine insemination (IUI) in conjunction with follicle monitoring and physiologic hormone replacement therapy. She conceived on the eighth cycle of treatment and delivered a healthy baby. Our report calls for a concerted effort to define the best methods by which to optimize fertility for women who have POI.

RESUMO

Abnormalities in the X-linked FMR1 gene are associated with a constellation of disorders, which have broad and profound implications for the person first diagnosed, and extended family members of all ages. The rare and pleiotropic nature of the associated disorders, both common and not, place great burdens on (1) the affected families, (2) their care providers and clinicians, and (3) investigators striving to conduct research on the conditions. Fragile X syndrome, occurring more severely in males, is the leading genetic cause of intellectual disability. Fragile X associated tremor and ataxia syndrome (FXTAS) is a neurodegenerative disorder seen more often in older men. Fragile X associated primary ovarian insufficiency (FXPOI) is a chronic disorder characterized by oligo/amenorrhea and hypergonadotropic hypogonadism before age 40 years. There may be significant morbidity due to: (1) depression and anxiety related to the loss of reproductive hormones and infertility; (2) reduced bone mineral density; and (3) increased risk of cardiovascular disease related to estrogen deficiency. Here we report the case of a young woman who never established regular menses and yet experienced a 5-year diagnostic odyssey before establishing a diagnosis of FXPOI despite a known family history of fragile X syndrome and early menopause. Also, despite having clearly documented FXPOI the woman conceived spontaneously and delivered two healthy children. We review the pathophysiology and management of FXPOI. As a rare disease, the diagnosis of FXPOI presents special challenges. Connecting patients and community health providers with investigators who have the requisite knowledge and expertise about the FMR1 gene and FXPOI would facilitate both patient care and research. There is a need for an international natural history study on FXPOI. The effort should be coordinated by a global virtual center, which takes full advantage of mobile device communication systems.

RESUMO

Catholic doctrine's strict prohibition on abortion can lead clinicians or institutions to conscientiously refuse to provide abortion, although a legal duty to provide abortion would apply to anyone who refused. Conscientious refusals by clinicians to end a pregnancy can constitute murder or reckless homicide under American law if a woman dies as a result of such a refusal. Such refusals are not immunized from criminal liability by the constitutional right to the free exercise of religion or by statutes that confer immunity from criminal homicide prosecution. Core principles of the rule of law require the state to protect the lives of all persons equally and to place the life and health of persons above any the interests of providers have in moral integrity or in respecting the moral status of prenatal humans. In some states criminal liability related to conscientious objection also applies to corporate hospital officials.

RESUMO

To make an informed choice to participate in a genome sequencing study that may yield primary and secondary findings, one understands relevant information in the context of personal values. Consent forms to enroll in a sequencing study can be long and complex. The efficacy of the professional encounter to consider the information contained in the consent form and make an informed choice is unknown. Women diagnosed with primary ovarian insufficiency and eligible for a sequencing study were randomized to participate in one of two encounters with a genetic counselor: a consent intervention using a lower literacy, less dense form or a standard consent encounter. Data were complete for 188 of 225 participants. The average time was 32 min for the intervention and 34 min for the standard, with the intervention encounter generating more questions from participants. At six weeks following consent, no differences were found between the two groups in primary outcomes: 'sequencing benefits' knowledge (d = 0.12, 95%CI: -0.03,0.27), 'sequencing limitations' knowledge (d = 0.04, 95%CI: -0.13,0.21), expected personal benefits (d = -0.01, 95%CI: -0.26,0.23), and decisional conflict (d = 0.04, 95%CI: -0.14,0.21). Although intentions to learn secondary variants were high, only 60% (113) of participants made an informed choice as defined by the multi-dimensional model of informed choice. We found that a modified consent intervention was as effective as a standard encounter and led to more interaction. Our data suggest that making decisions to receive secondary findings may be particularly challenging and in need of further investigation to achieve informed choice.

RESUMO

Most clinicians are not prepared to provide integrated personal care to address all the clinical needs of women with primary ovarian insufficiency. Design thinking is an engineering methodology used to develop and evaluate novel concepts for systems operation. Here we articulate the need for a seamlessly integrated mobile health system to support genomic research as well as patient care. We also review the pathophysiology and management of primary ovarian insufficiency. Molecular understanding regarding the pathogenesis is essential to developing strategies for prevention, earlier diagnosis, and appropriate management of the disorder. The syndrome is a chronic disorder characterized by oligo/amenorrhea and hypergonadotropic hypogonadism before age 40 years. There may be significant morbidity due to: 1) depression and anxiety related to the loss of reproductive hormones and infertility; 2) associated autoimmune adrenal insufficiency or hypothyroidism; and 3) reduced bone mineral density and increased risk of cardiovascular disease related to estrogen deficiency. Approximately 5% to 10% of women with primary ovarian insufficiency conceive and have a child. Women who develop primary ovarian insufficiency related to a premutation in FMR1 are at risk of having a child with fragile X syndrome, the most common cause of inherited intellectual disability. In most cases of spontaneous primary ovarian insufficiency no environmental exposure or genetic mechanism can be identified. As a rare disease, the diagnosis of primary ovarian insufficiency presents special challenges. Connecting patients and community health providers in real time with investigators who have the requisite knowledge and expertise would help solve this dilemma.

RESUMO

Primary ovarian insufficiency (POI) is a rare but important cause of ovarian hormone deficiency and infertility in women. In addition to causing infertility, POI is associated with multiple health risks, including bothersome menopausal symptoms, decreased bone density and increased risk of fractures, early progression of cardiovascular disease, psychologic impact that may include depression, anxiety, and decreased perceived psychosocial support, potential early decline in cognition, and dry eye syndrome. Appropriate hormone replacement therapy (HRT) to replace premenopausal levels of ovarian sex steroids is paramount to increasing quality of life for women with POI and ameliorating associated health risks. In this review, we discuss POI and complications associated with this disorder, as well as safe and effective HRT options. To decrease morbidity associated with POI, we recommend using HRT formulations that most closely mimic normal ovarian hormone production and continuing HRT until the normal age of natural menopause, ∼50 years. We address special populations of women with POI, including women with Turner syndrome, women with increased risk of breast or ovarian cancer, women approaching the age of natural menopause, and breastfeeding women.

RESUMO

Bilateral oophorectomy performed in women before they are menopausal induces surgical primary ovarian insufficiency, an acute and chronic deficiency of the hormones normally produced by the ovaries. Without hormone replacement therapy (HRT) most of these women develop severe symptoms of estrogen (E) deficiency and are at increased risk for osteoporosis, cardiovascular disease, cognitive decline, dementia, and the associated increases in morbidity and mortality. In cases in which a hysterectomy has been performed at the time of bilateral oophorectomy transdermal or transvaginal E2 replacement therapy without cyclic progestin replacement is the optimum hormonal management for these women. There is substantial evidence this approach even reduces the risk for breast cancer. Unfortunately, unwarranted fear of all menopausal HRTs has become widespread following the reports of the Women's Health Initiative studies. This fear has led to a steep decline in use of E therapy, even in women in whom HRT is clearly indicated. Discussion of possible ovarian conservation in women who are premenopausal is an integral part of the preoperative planning for any women undergoing hysterectomy. Timely and effective HRT for women who will experience surgical primary ovarian insufficiency is clearly indicated.

RESUMO

Autoimmune polyendocrine syndrome type 1 (APS1) is a monogenic disorder that features multiple autoimmune disease manifestations. It is caused by mutations in the Autoimmune regulator (AIRE) gene, which promote thymic display of thousands of peripheral tissue antigens in a process critical for establishing central immune tolerance. We here used proteome arrays to perform a comprehensive study of autoimmune targets in APS1. Interrogation of established autoantigens revealed highly reliable detection of autoantibodies, and by exploring the full panel of more than 9000 proteins we further identified MAGEB2 and PDILT as novel major autoantigens in APS1. Our proteome-wide assessment revealed a marked enrichment for tissue-specific immune targets, mirroring AIRE's selectiveness for this category of genes. Our findings also suggest that only a very limited portion of the proteome becomes targeted by the immune system in APS1, which contrasts the broad defect of thymic presentation associated with AIRE-deficiency and raises novel questions what other factors are needed for break of tolerance.
