Survey of Third-Party Parenting Options Associated With Fertility Preservation Available to Patients With Cancer Around the Globe.

Purpose: In the accompanying article, "Survey of Fertility Preservation Options Available to Patients With Cancer Around the Globe," we showed that specific fertility preservation services may not be offered at various sites around the world because of cultural and legal barriers. We assessed global and regional experiences as well as the legal status of third-party reproduction and adoption to serve as a comprehensive international data set and resource for groups that wish to begin oncofertility interventions. Methods: We provide data on the legalities of third-party assisted reproductive technologies and other family-building options in the 28 oncofertility-practicing countries surveyed. Results: We found regional and country differences that will be important in the development of tailored resources for physicians and for patient brochures that are sensitive to these local restrictions and cultural norms. Conclusion: Because many patients first consult Web-based materials, the formal assessment of the availability of these options provides members of the global oncofertility community with data to which they might otherwise not have ready access to better serve their patients.

Survey of Fertility Preservation Options Available to Patients With Cancer Around the Globe.

Purpose: Oncofertility focuses on providing fertility and endocrine-sparing options to patients who undergo life-preserving but gonadotoxic cancer treatment. The resources needed to meet patient demand often are fragmented along disciplinary lines. We quantify assets and gaps in oncofertility care on a global scale. Methods: Survey-based questionnaires were provided to 191 members of the Oncofertility Consortium Global Partners Network, a National Institutes of Health-funded organization. Responses were analyzed to measure trends and regional subtleties about patient oncofertility experiences and to analyze barriers to care at sites that provide oncofertility services. Results: Sixty-three responses were received (response rate, 25%), and 40 were analyzed from oncofertility centers in 28 countries. Thirty of 40 survey results (75%) showed that formal referral processes and psychological care are provided to patients at the majority of sites. Fourteen of 23 respondents (61%) stated that some fertility preservation services are not offered because of cultural and legal barriers. The growth of oncofertility and its capacity to improve the lives of cancer survivors around the globe relies on concentrated efforts to increase awareness, promote collaboration, share best practices, and advocate for research funding. Conclusion: This survey reveals global and regional successes and challenges and provides insight into what is needed to advance the field and make the discussion of fertility preservation and endocrine health a standard component of the cancer treatment plan. As the field of oncofertility continues to develop around the globe, regular assessment of both international and regional barriers to quality care must continue to guide process improvements.

Corifollitropin alfa compared to daily rFSH or HP-HMG in GnRH antagonist controlled ovarian stimulation protocol for patients undergoing assisted reproduction.

OBJECTIVE: This study aimed to compare the outcomes of controlled ovarian stimulation (COS) with corifollitropin alfa versus daily recombinant follicle-stimulating hormone (rRFSH) or highly purified human menopausal gonadotropin (HP-HMG) in patients undergoing in vitro fertilization (IVF) cycles based on gonadotropin-releasing hormone (GnRH) antagonist protocols. The primary endpoints were total number of oocytes and mature oocytes. METHODS: This retrospective study looked into 132 controlled ovarian stimulation cycles from IVF or oocyte cryopreservation performed in a private human reproduction center between January 1 and December 31, 2014. Enrollment criteria: women aged < 40 years submitted to COS with corifollitropin alfa 100µg or 150µg (n = 26) and rFSH or HP-HMG in the first seven days of treatment with daily doses of 150-225 IU (n = 106); all subjects were on GnRH antagonist protocols. RESULTS: The groups had similar mean ages and duration of stimulation. The mean number ± standard deviation of total aspirated oocytes and MII oocytes was 11.9±10 and 10.3±7.9 in the corifollitropin alfa group, and 10.9±7.2 and 8.6±5.7 in the group on rFSH or HMG (p>0.05). There were no significant differences in fertilization (76.9% vs. 76.8%, p=1.0), biochemical pregnancy (66.7% vs. 47.2%, p=0.1561) or embryo implantation rates (68.7% vs. 50%, p=0.2588) between the groups using corifollitropin alfa and rFSH or HMG, respectively. CONCLUSIONS: Corifollitropin alfa seems to be as effective as rFSH or HP-HMG when used in the first seven days of ovulation induction for patients undergoing assisted reproduction in GnRH antagonist protocols.

Indução de ovulação em pacientes com tumor estrogênio­dependente: diretrizes clínicas da Sociedade Brasileira de Reprodução Humana / Ovulation induction in patients with estrogen­dependent tumors: a Brazilian Society of Human Reproduction clinical practice guideline

A oncofertilidade é um campo de interesse interdisciplinar de desenvolvimento recente que busca mesclar os conhecimentos em oncologia e medicina reprodutiva, com a contribuição das técnicas de reprodução assistida, para o desenvolvimento de estratégias de preservação da função gonadal e oferecer a possibilidade da procriação biológica aos sobreviventes de câncer. As estratégias de preservação da fertilidade feminina em pacientes oncológicas atualmente aceitas para a prática rotineira são a criopreservação de embriões e a criopreservação de oócitos maduros. Ocorre que, para execução de ambos, a indução de ovulação é obrigatória e, com ela, vêm os riscos teóricos de estimulação do crescimento de tumores estrogênio­dependentes e a postergação do início do tratamento antineoplásico. Os protocolos de estimulação ovariana de início aleatório contemplam a intenção de se minimizar o atraso no início da quimioterapia ou radioterapia e o bloqueio ao crescimento tumoral e oferecem resultados satisfatórios, semelhantes aos obtidos em protocolos de início habitual. Apresentamos neste artigo as diretrizes clínicas da Sociedade Brasileira de Reprodução Humana para indução de ovulação em pacientes com tumor estrogênio­dependente.(AU)

Oncofertility is an interdisciplinary interest field of recent development, which aims to merge the knowledge in oncology and reproductive medicine, with the help of assisted reproductive technologies, to develop strategies for gonadal function preservation and to offer the possibility of biological procreation to cancer survivors. Preservation strategies of female fertility in oncological patients currently accepted for routine practice are the cryopreservation of embryos and cryopreservation of mature oocytes. It happens that ovulation induction is mandatory for executing both strategies, and with it the theoretical risk of stimulation of estrogen­dependent tumors growth and the postponement of anti­neoplastic treatment. Random­start ovarian stimulation protocols include the intention of minimizing the delay in onset of chemo­radiotherapy and to block tumor growth, providing satisfactory results, similar to those obtained in the usual beginning protocols. This article presents the clinical guidelines of the Brazilian Society of Human Reproduction for ovulation induction in patients with estrogen­dependent tumors.(AU)

The association between follicular size at the time of spontaneous rupture and pregnancy rates in clomiphene citrate treated PCOS patients in coit cycles.

OBJECTIVE: To investigate the follicular size at spontaneous rupture on pregnancy rate in patients with polycystic ovary syndrome (PCOS) undergoing clomiphene citrate (CC) ovulation. DESIGN: Cross-sectional study. PATIENTS AND METHODS: One hundred and four women with ovulatory cycles after use of CC followed by ultrasound to determine the follicle size at the time of rupture, which was subsequently correlated with the occurrence of pregnancy or not in coit cycles. RESULTS: In the group of follicular rupture at a mean diameter ≤25 mm (n = 54), pregnancy rate was 35.1% and when follicular rupture occurred at a mean diameter >25 mm (n = 50), it was 34% (p > 0.05). When different diameters at follicular rupture were randomly correlated with the pregnancy rate, there was no significant difference. CONCLUSION: Our data suggest that the occurrence of pregnancy after ovulation induction with CC in women with PCOS is not associated with follicle size at the time of rupture.

Avaliação genética pré-implantacional: visão geral / Preimplantation genetic testing: an overview

Identificar um embrião com alto potencial de implantação é um dos maiores desafios da medicina reprodutiva e um passo fundamental em direção à transferência de um único embrião. O diagnóstico genético pré-implantacional permite identificar alterações genéticas ou cromossômicas nos embriões em divisão antes de serem transferidos, enquanto o rastreamento genético pré-implantacional realiza a triagem em embriões quanto às anomalias cromossômicas frequentes. Dentre as limitações encontradas, o mosaicismo é responsável por grande parcela de erros de diagnóstico, e os altos custos das técnicas de hibridização in situ por fluorescência e reação em cadeia da polimerase ainda dificultam a implantação do diagnóstico genético pré-implantacional e do rastreamento genético pré-implantacional de forma rotineira. Este artigo pretende apresentar uma visão geral acerca das modalidades de avaliação genética préimplantacional disponíveis e seus resultados e avaliar criticamente a inserção dessas tecnologias entre os recursospropedêuticos para assistência reprodutiva.

The identification of an embryo with high implantation potential is one of the greatest challenges in reproductive medicine and a vital step towards transferring a single pre-embryo. Preimplantation genetic diagnosis allows the identification of genetic or chromosomal alterations in pre-embryos before they are transferred to the uterus, while preimplantation geneticscreening determines alleatory frequent chromosomal abnormalities. Among limitations, mosaicism is responsible for a large proportion of misdiagnosis, and the high costs of fluorescent in situ hybridization and polymerase chain reaction still hinder the implementation of preimplantation genetic diagnosis and preimplantation genetic screening as a routine. Thisarticle aims to present an overview of possible modalities of preimplantation genetic evaluation and their results and to criticallyevaluate the insertion of those technologies in the propaedeutical tools in reproductive assistance.

Estudo multicentro da eficácia e segurança da lomefloxacina versus sulfametoxazol/trimetoprim no tratamento de cistite em mulheres / Multicenter study on the efficacy and safety of lomefloxacin versus trimethoprim and sulfamethoxazole in the treatment of lower urinary tract infection in women

A lomeflomexacina (maxaquim), uma nova quinolona difluorada, e o trimetoprim/sulfametoxazol (bactrim) foram comparados no tratamento de mulheres adultas com infecçöes urinárias simples. O estudo foi randomizado, prospectivo, controlado e realizado em seis centros. Um total de 57 pacientes foram estudados: 30 em tratamento com Bactrim e 27 em tratamento com Maxaquim. As pacientes receberam 400mg de lomefloxacina via oral, de 12/12 horas, por três dias ou 160mg/800mg trimetoprim/sulfametoxazol via oral, de 12/12 horas por sete dias. Eschericia coli, Klebsiella e Proteus mirabilis foram os patogenos mais frequentemente isolados. Cinco a nove dias pós-terapia, cura bacteriológica foi verificada em 92,6 por cento das pacientes tratadas com lomefloxacina e em 90 por cento das pacientes do grupo do trimetoprim/sulfametoxazol. Sucesso clínico foi constatado em 96,3 por cento das pacientes no grupo da lomefloxacina e em 96,7 por cento das pacientes trimetoprim/sulfametaxol. Efeitos adversos, provavelmente relacionados com o tratamento, foram nauseas, desconforto gástrico de moderada intensidade e mal estar com nauseas de forte intensidade para o grupo trimetoprim/sulfametoxazol e epigastralgia de fraca intensidade para o grupo lomefloxacina. O tratamento único com lomefloxacina foi eficaz e bem tolerado no tratamento das infeçöes do trato urinário causadas por patogenos sensíveis a esta droga
