ABSTRACT

SUMMARY OBJECTIVE: Since the start of the COVID-19 pandemic, there has been interest in the impact of both SARS-CoV-2 infection and pandemic-induced social restrictions on male reproductive health. This study aimed to evaluate the spermiogram values of men who presented for infertility during the pandemic compared with the previous 2 years. METHODS: Patients who presented to a urology outpatient clinic for the first time due to infertility were included. The patients' age, semen volume, and spermiogram results were recorded. Based on the presentation date, the patients were divided into prepandemic group 1 (March 2018-February 2019), prepandemic group 2 (March 2019-February 2020), and pandemic group (March 2020-February 2021) for comparison. RESULTS: A total of 594 patients were included. There was no significant difference between the three groups in terms of the number of patients who presented for infertility (207, 190, and 197 patients, respectively; p=0.691). The mean age was 36.6±7.2 in the prepandemic group 1, 35.5±7.1 in the prepandemic group 2, and 33.1±6.3 in the pandemic group. Patients who presented during the pandemic were significantly younger (p<0.001). There were no differences between the groups in terms of semen volume (p=0.910) or rates of normospermia and pathological spermiogram findings (p=0.222). CONCLUSIONS: In the first year of the COVID-19 pandemic, there was no significant difference in the number of patients who presented for infertility or in their spermiogram results compared with 2018 and 2019. However, it is noteworthy that the patients were significantly younger during the pandemic than in the previous 2 years.

ABSTRACT

A OMS estima que mais de 1 milhão de infecções sexualmente transmissíveis é adquirido todos os dias em todo o mundo. Dentre as ISTs, a clamídia é a principal causa da doença inflamatória pélvica e de infertilidade em mulheres em todo o mundo. Para esta pesquisa foi realizada uma revisão sistemática. O processo de revisão foi realizado através de uma busca na base de dados eletrônica, como PubMed, Scielo, Google Acadêmico, e em livros didáticos, utilizando os descritores infertilidade, IST, Chlamydia trachomatis. O objetivo deste estudo é buscar na literatura estudos que relatam a relação da Chlamydia trachomatis (CT) com problemas de infertilidade e os melhores métodos de diagnósticos e custo/benefício. O estudo concluiu que a CT é uma IST bastante prevalente no mundo e preocupante devido às complicações que muitas vezes são irreversíveis, como a infertilidade. Dentre os testes existentes no mercado, a PCR e a captura híbrida foram os que apresentaram melhor sensibilidade e especificidade.


The WHO estimates that more than 1 million sexually transmitted infections are acquired every day worldwide. Among STIs, chlamydia is the main cause of pelvic inflammatory disease and infertility in women worldwide. For this research a systematic review was carried out. The review process was carried out through a search in the electronic database, such as Pubmed, Scielo, Google Scholar and in textbooks, using the descriptors infertility, IST, Chlamydia trachomatis. The aim of this study is to search the literature for studies that report the relationship between CT and infertility problems and the best diagnostic methods and cost benefit. The study concludes that CT is an STI that is quite prevalent in the world and worrisome due to complications that are often irreversible such as infertility. Among the tests on the market, PCR and hybrid capture showed the best sensitivity and specificity.

ABSTRACT

O objetivo deste trabalho foi analisar os aspectos emocionais presentes no processo de reprodução humana assistida (RHA), por meio de uma revisão interativa da literatura. As bases de dados utilizadas foram PubMed, BVS e Periódicos Capes, com os descritores "infertility" AND "reproductive techniques" AND "emotions". Foram incluídos e analisados 24 artigos dos últimos cinco anos (2015 a 2020). Os resultados indicam que existem diversos sentimentos negativos que permeiam os casais infé rteis, especialmente quando existem falhas no tratamento. O apoio social durante o tratamento em RHA melhora a qualidade de vida do casal e diminui o sofrimento emocional. As estratégias de enfrentamento utilizadas pelos casais inférteis e as intervenções terapêuticas também foram avaliadas como positivas para o manejo do estresse, da ansiedade e da depressão. As diferenças de gênero apareceram nos estudos e reiteram a relevância das relações de gênero, indicando a necessidade de intervenções diferentes para homens e mulheres.(AU)


The aim of this work was to analyze the emotional aspects present in the assisted human reproduction (RHA) process, through an interactive literature review. The databases used were PUBMED, BVS and CAPES journals, with the descriptors "infertility" AND « reproductive techniques" AND "emotions." 24 articles from the last five years (2015 to 2020) were included and analyzed. The results indicate that there are several negative feelings that permeate infertile couples, especially when treatment failures, social support during RHA treatment improves the couple's quality of life and reduces emotional distress. The coping strategies used by infertile couples and interventions therapeutics were also evaluated as positive for the management of stress, anxiety and depression. The gender differences appeared in the studies and reiterate the relevance of gender relations, indicating the need for different interventions for men and women.(AU)

ABSTRACT

Introducción: La infertilidad afecta al 15 por ciento de las parejas en edad fértil, de las que aproximadamente 4-8 por ciento requerirán técnicas de reproducción asistida de alta tecnología. Con la incorporación de la mujer a la vida laboral y la consiguiente postergación de la maternidad es posible el aumento de la infertilidad. La hormona antimülleriana en la mujer se produce por las células de la granulosa. Esta regula el reclutamiento de folículos, su crecimiento y previene el agotamiento folicular, por lo que constituye una importante herramienta en los protocolos de inducción de la ovulación. Objetivo: Evaluar los niveles de la hormona antimülleriana como marcador de respuesta ovárica en pacientes tratadas por fertilización in vitro. Método: Se realizó un estudio descriptivo, observacional y de corte transversal en la consulta protocolizada de Reproducción Asistida del Hospital Clínico Quirúrgico Hermanos Ameijeiras, en el periodo comprendido de abril 2017 hasta abril 2019. La muestra quedó conformada por 137 mujeres que participaron en esta consulta. Se empleó estadística descriptiva e inferencial. Resultados: La edad promedio de las pacientes fue de 33,1 ± 7,4 años. Predominó la concentración sérica normal de la hormona antimülleriana en mujeres entre 31-35 años (26,3 por ciento), nivel normal de FSH en (39,4 por ciento), recuento de folículos antrales normal (24,1 por ciento), buena calidad ovocitaria (39,4 por ciento), y buena calidad embrionaria (36,5 por ciento). Conclusiones: El nivel sérico de la hormona antimülleriana se asoció significativamente a la edad, la hormona folículo estimulante, el recuento de los folículos antrales, y la calidad ovocitaria y embrionaria(AU)


Introduction: Infertility affects to 15 percent of the couples in childbearing age, and approximately 4-8 percent of them will need high-tech assisted reproduction techniques. With the participation of women in work life and the subsequent delay of maternity, it is possible the increase of infertility. Anti-Müllerian in women is produced by granular cells. These cells control the recruitment of follicles, their growth and prevent follicles exhaustion; therefore, it represents an important tool in the protocols of ovulation induction. Objective: Assess the levels of anti-Müllerian hormone as a marker in the ovarian response in patients treated with in vitro fertilization. Methods: It was conducted a descriptive, observational and cross-sectional study in the consultation of Assisted Reproduction in "Hermanos Ameijeiras" Surgical Clinical Hospital, in the period April, 2017 - April, 2019. The sample was formed by 137 women who attended to this consultation. It was used descriptive and inferential statistics. Results: Average age of the patients was 33,1 ± 7,4 years old. There was predominance of normal serum concentration of anti-Müllerian hormone in women among 31-35 years old (26,3 percent), FSH normal level in (39,4 percent), normal recount of antral follicles (24,1 percent), good oocyte quality (39,4 percent), and good embryonic quality (36,5 percent). Conclusions: The serum level of the anti-Müllerian hormone was significantly associated to age, the follicle-stimulating hormone, the recount of antral follicles, and the oocyte and embryonic quality(AU)

ABSTRACT

La evidencia clínica que ha permitido relacionar la diabetes mellitus con la infertilidad se basa en la importancia del metabolismo de la glucosa durante el proceso de espermatogénesis, debido a que en los episodios tanto de hipoglucemia como de hiperglucemia pueden ocurrir cambios epigenéticos en algunas proteínas involucradas en la espermatogénesis. En la presente comunicación se describen los aspectos teóricos de los efectos de la diabetes sobre el líquido seminal con énfasis en la espermatogénesis(AU)


The clinical evidence that has made it possible to link diabetes mellitus with infertility is based on the importance of glucose metabolism during the spermatogenesis process, because in episodes of both hypoglycemia and hyperglycemia, epigenetic changes can occur in some proteins involved in spermatogenesis. This communication describes the theoretical aspects of the effects of diabetes on seminal fluid with emphasis on spermatogenesis(AU)

ABSTRACT

Os sinais clínicos da síndrome de Klinefelter foram observados pela primeira vez em 1942, mas sua etiologia só foi definida em 1959. Trata-se de uma condição genética na qual pelo menos um cromossomo X extra é adicionado ao cariótipo masculino normal (46,XY) e acomete cerca de 1 em cada 500 homens. É caracterizada por variabilidade fenotípica que leva a atraso ou ausência de diagnóstico, com uma estimativa de 50% a 75% de homens com Síndrome de Klinefelter nunca obterem o diagnóstico correto. Apesar de o cariótipo clássico (47,XXY) ser encontrado em 80%-90% dos pacientes e o mosaicismo (46,XY/47,XXY) nos 10% restantes, outros cariótipos podem ser encontrados menos frequentemente. Nesse sentido, este estudo tem por finalidade descrever os possíveis cariótipos identificados nos pacientes com Síndrome de Klinefelter. Os resultados mostram que a Síndrome de Klinefelter é usualmente diagnosticada na vida adulta e caracterizada por uma heterogeneidade citogenética quanto aos cariótipos possíveis apresentados pelos pacientes afetados. A condição foi diagnosticada precocemente quando associada à anomalia dos cromossomos autossomos, excesso de cromossomos X extra ou quando foi realizado diagnóstico pré-natal por idade materna avançada. É imprescindível que os profissionais de saúde, em especial os médicos, se familiarizem mais com essa condição, pois o diagnóstico correto e precoce permite a intervenção e tratamento adequados visando melhorar a qualidade de vida desses indivíduos.

ABSTRACT

Infertilidade é uma condição que afeta muitos casais. Entre 30% e 40% de mulheres em fertilização assistida apresentam depressão e ansiedade. O relacionamento conjugal também é atingido. Fatores psicossociais que podem tornar indivíduos inférteis mais vulneráveis ao estresse são: características de personalidade, sentimentos de ameaça ou de perda relacionados à infertilidade, percepção de pouco controle sobre a condição de infertilidade e o resultado do tratamento, utilização frequente de estratégias de enfrentamento caracterizadas por evitação e fuga, insatisfação conjugal e dificuldade de comunicação do casal e rede de apoio social insuficiente. Observou-se pequena associação, mas significativa, entre estresse e angústia e a redução das chances de gravidez com o tratamento. A infertilidade e as abordagens terapêuticas para fertilização provocam mudanças na autoestima, no relacionamento e na função sexual. As disfunções sexuais atingem as mulheres (43% a 90%) e os homens (48% a 58%). Além do sofrimento psíquico nas mulheres e em seus parceiros, o comprometimento da vida sexual do casal pode afetar a continuidade do relacionamento, inclusive para o enfrentamento dos desafios do casal que se torna pai e mãe, quando o tratamento é bem-sucedido. A confirmação de que a resiliência pode desempenhar função de proteção nesse percurso, fortalece a importância do acompanhamento psicológico, visando otimizar todos os recursos para melhor superação dessa fase da vida dos casais.

ABSTRACT

RESUMEN Se presentaron dos pacientes a las cuales se les realizó una miomectomía en los meses de enero y marzo de 2017, en la localidad de Luanda, Angola. Ambas fueron atendidas en la consulta de Ginecología por: aumento de volumen del abdomen, sangramiento genital durante la menstruación y fuera de ella, síntomas compresivos caracterizados por urgencia miccional y estreñimiento, además de infertilidad. Se les realizaron: exámenes de laboratorio, ultrasonido ginecológico y renal, así como histerosalpingografía. Después del análisis de estos exámenes se les diagnosticó una miomatosis uterina múltiple; fueron remitidas al salón de operaciones con previo consentimiento informado y se les practicó una miomectomía múltiple sin complicaciones transoperatorias. Se conservó el útero en ambas pacientes, las cuales tuvieron una recuperación postoperatoria satisfactoria. Una de estas pacientes logró un embarazo cinco meses después de la cirugía.


ABSTRACT We present two patients who had a myomectomy in January and March 2017, in Luanda, Angola. Both were treated in the Gynecology consultation due to increased abdominal volume, genital bleeding during and between periods, compressive symptoms characterized by urinary urgency, constipation and infertility. Laboratory tests, gynecological and renal ultrasound, as well as hysterosalpingography were performed. After the analysis of these tests, they were diagnosed with multiple uterine myomas, referred to the operating room with prior informed consent and underwent a multiple myomectomy without transoperative complications. The uterus was preserved in both patients, who had a satisfactory postoperative recovery. One of these patients got pregnant five months after surgery.

ABSTRACT

Teniendo en cuenta que la infertilidad en parejas constituye un problema de Salud Pública en Cuba y ante la necesidad de determinar sus principales causas en parejas infértiles atendidas en consulta municipal de infertilidad Policlínico Guillermo Tejas Silva de la ciudad de Las Tunas. Se realizó un estudio descriptivo de corte transversal desde septiembre de 2017 a mayo del 2018, con un universo de 88 parejas, los datos fueron obtenidos de las historias clínicas. Las principa les causas de infertilidad femenina encontradas fueron los trastornos ovulatorios seguido por el factor tubárico, mientras que en la masculina las testiculares. Predominaron las edades de 29-35 años en mujeres y >35 años en hombres. Según la historia obstétrica anterior prevalecieron las gestaciones previas y abortos espontáneos. La mayoría de las parejas fueron a consulta por una infertilidad secundaria, sin embargo, prevaleció la causa mixta (50%), con una duración invo- luntaria de 4 a 6 años (40,91%). Los hallazgos encontrados en este estudio coinciden de forma general con la literatura científica; pero resultan significativos para contribuir a la solución de los problemas relacionados con la infertilidad en parejas de este municipio tunero


Infertility in couples constitutes a Public Health problem in Cuba. It is evident the need to deter- mine its main causes in infertile couples treated at the municipal infertility consultation at Guillermo Tejas Silva Polyclinic Hospital in the city of Las Tunas. A descriptive cross-sectional study was conducted from September 2017 to May 2018, with a universe of 88 couples, the data were obtained from medical records. The main causes of female infertility found were ovulatory disorders followed by the tubal factor, while in the male, there were testicular ones. The ages of 29-35 years in women and> 35 years in men predominated. According to the previous obstetric history, previous pregnancies and spontaneous abortions prevailed. Most of the couples were consulted for secondary infertility, however, the mixed cause prevailed (50%), with an involun- tary duration of 4 to 6 years (40.91%). The findings coincided with the scientific literature; but they are significant to contribute to the solution of problems related to infertility in couples in this municipality of Las Tunas.

ABSTRACT

Introdução A forma como a nossa sociedade lida com a noção de saúde e como constrói a ideia da doença é discricionária e, ao mesmo tempo em que impacta, ela é impactada pela disponibilidade de tratamentos de um complexo industrial biomédico. O caso específico a ser analisado nessa dissertação é o da infertilidade. De que forma essa condição é definida como doença? Por quais atores? Quais tratamentos são disponibilizados para essa doença? Quais conflitos de interesse estão presentes nessa definição? Como se dá a regulamentação dessas questões, no âmbito internacional, e no âmbito nacional? Objetivo O objetivo dessa dissertação é analisar de que forma, e por meio de quais atores, se constrói a dupla condição da infertilidade atualmente: a sua definição como doença, e a noção de que a fertilidade é uma condição natural a ser preservada, uma potencialidade dos corpos femininos. Considera-se, para tanto, que tais construções são permeadas pelo mercado das tecnologias de reprodução assistida (TRAs) e são objeto de regulamentação nacional e internacionalmente. Métodos Foi realizado um estudo baseado em metodologia de caráter qualitativo, incluindo análise documental. Foram analisadas informações de fontes primárias. Foi feita análise documental da Classificação Internacional de Doenças (CID) e da Organização Mundial de Saúde - e seus parceiros -, tendo em vista serem essas as fontes reconhecidas mundialmente para a definição de condições patológicas. Ademais, foi analisado o papel regulamentador dessas entidades internacionais, assim como, dos atores, em âmbito nacional, responsáveis pela regulamentação da prática médica no campo da infertilidade e do mercado das Tecnologias de Reprodução Assistida (TRAs). A fim de propiciar um panorama de análise mais completo, foram estudados os websites das dez principais clínicas privadas da Cidade de São Paulo em busca de quatro conceitos-chave: a definição de "infertilidade" apresentada pelas clínicas, a indicação clínica para o procedimento de fertilização in vitro, o termo usado para se referir ao procedimento de congelamento de gametas femininos e as taxas de efetividade apresentadas nos websites para os tratamentos de infertilidade. Foram estudados os relatórios financeiros e balanços das principais empresas do complexo tecno-científico da biomedicina que atuam na cidade de São Paulo, a fim de identificar as tecnologias/equipamentos sendo desenvolvidos pelas empresas, quais mercados são alvo delas e a relação desse movimento com a proliferação de condições patológicas relacionadas à infertilidade. Resultados A definição da infertilidade como patologia é feita pela OMS por meio da Classificação Internacional de Doenças e, conforme observado, é adotada mundialmente, inclusive pelas clínicas de Reprodução Assistida paulistanas. Essa definição é feita pela OMS e por seus parceiros, os quais se apresentam como instituições neutras e de caráter técnico, apesar de serem patrocinadas direta ou indiretamente pelas indústrias responsáveis por ofertarem tecnologias reprodutivas. Os outros atores partícipes nessa definição consistem em associações de clínicas de reprodução assistida e médicos dessa área, as quais além do próprio interesse em expandirem seus negócios possuem, muitas vezes, financiamento direto das mesmas indústrias. Conclusão A partir dessas análises foi possível identificar o caráter não-neutro da definição da infertilidade como doença, a nova perspectiva da fertilidade como potencial reprodutivo, a influência de atores do mercado na construção desses conceitos, assim como os impactos desses conceitos no mercado das tecnologias para reprodução assistida. Ademais, observou-se a frágil regulamentação existente nesse campo, tanto no cenário internacional como no cenário nacional e a atuação limitada do setor público nessa seara. O poder público está ausente das decisões sobre a adoção das TRAs e sobre a sua aplicação nos corpos das mulheres, da mesma forma que não intervém nas discussões conceituais acerca da condição patológica atribuída à infertilidade pelo campo biomédico. A regulamentação estatal se limita a questões sanitárias, por meio da atuação da ANVISA, o que permite a autoregulamentação da classe médica e do mercado, os quais são permeados por contradições e conflitos de interesse.


Introduction The way in which our society deals with the notion of health and how the idea of disease is built is discretionary and at the same time that it impacts it is impacted by the availability of treatments of the industrial biomedical complex. The specific case to be analyzed in this dissertation is infertility. In what way is this condition defined as a disease? By whom? What treatments are made available for this disease? What conflicting economic interests are present in this definition? How are these processes regulated in both the international and domestic field? Objectives This dissertation aims to analyze how and by means of which participants the dual notion of infertility is conceived currently: its definition as a disease and the idea that fertility is a natural condition to be preserved, a potential of the female body. To do so, it is deemed that such constructions are pervaded by the market of Assisted Reproductive Technologies (ARTs) and are subject to both domestic and international regulations. Methods In order to achieve this aim, a study was performed based upon methodology of a qualitative nature, including documentary analysis. A documentary analysis was made of the International Classification of Diseases (ICD) and of the World Health Organization (WHO) - and its partners -, bearing in mind that it is acknowledged throughout the world for defining pathological conditions. Furthermore, the regulating role of these international entities was analyzed, as was that of those taking part in the Domestic scope, responsible for regulating medical practice in the field of infertility and the market of Assisted Reproductive Technologies (ARTs). In order to provide a more complete overview, the websites of the ten main private clinics in São Paulo were studied seeking four key concepts: the definition of "infertility" presented by the clinics, the clinical indication for the procedure of fertilization in vitro, the term used to refer to the procedure of freezing female gametes and the effectiveness rates displayed on the websites for treating infertility. The main participants of the industrial biomedical complex, focusing on the pharmaceutical industry and medical equipment were identified, as was any relationship thereof with the main fertility clinics of São Paulo city. To do so, the financial reports and balance sheets of the main companies of the technical-scientific complex of biomedicine performing in São Paulo city were studied, in order to identify the technology/equipment being developed by companies, their target markets and the relationship of this movement with the proliferation of pathological conditions related to infertility. Results The definition of infertility as a pathology in the ICD elaborated by the World Health Organization - WHO - is adopted worldwide including by clinics in São Paulo. This definition is elaborated by the WHO and its partners which are funded by the Industry of ART even though they portray an image of neutrality and technical-scientific character. The other players involved in these definitions are fertility clinics' associations and doctors that provide fertility treatments, which have their own business interests and sometimes are even funded directly by this Industry. Conclusion These analyses allowed the identification of the non-neutral nature of the definition of infertility as a disease, the new perspective of fertility as reproductive potential, the influence of entities in the market in building these concepts, as well as the impact of these concepts on the assisted reproductive technology market. Furthermore, the lack of string regulations in this field was noted, in both the international and domestic scenarios and the limited performance of the public sector in this area, which allows the self-regulation of the medical class and the market, pervaded with contradictions and self- interest.

ABSTRACT

Meiosis is an essential step in gametogenesis which is the key process in sexually reproducing organisms as meiotic aberrations may result in infertility. In meiosis, programmed DNA double-strand break (DSB) formation is one of the fundamental processes that are essential for maintaining homolog interactions and correcting segregation of chromosomes. Although the number and distribution of meiotic DSBs are tightly regulated, still abnormalities in DSB formation are known to cause meiotic arrest and infertility. This review is a detailed account of molecular bases of meiotic DSB formation, its evolutionary conservation, and variations in different species. We further reviewed the mutations of DSB formation genes in association with human infertility and also proposed the future directions and strategies about the study of meiotic DSB formation.

ABSTRACT

Pregnancy losses are a major concern in livestock industry due to their economic impact on producers. Campylobacter fetus subspecies fetus (Cff) and C. fetus subspecies venerealis (Cfv) are directly related to reproductive failures in ruminants. Cff colonizes the gastrointestinal tract of a wide range of hosts leading to abortion, while Cfv is restricted to genital tract being generally associated to infertility in bovine. Considering the great economic losses related to campylobacteriosis in cattle and ovine herds, this study aims to investigate the occurrence of C. fetus, considering Cff and Cfv subspecies, in bovine and ovine spontaneously aborted fetuses in state of Rio Grande do Sul, Brazil. In this study, samples of abomasal fluid collected from 30 spontaneously aborted bovine (n = 18) and ovine (n = 12) fetuses were investigated for the detection of Campylobacter fetus throughout conventional PCR. Positive fetuses for C. fetus presence were further analyzed by molecular assays for Cff and Cfv detection, in order to determine subspecies identification. When available, samples of the main organs of the thoracic and abdominal cavities, as well as the brain, skeletal muscle, eyelid, skin, and placenta were collected for further histopathological analyses and bacterial culture, aiming to assess the presence of infection lesions and pathogens in those sites, respectively. Additionally, RT-qPCR assays were also performed for the detection of ruminant pestivirus, in order to detect bovine viral diarrhea cases. Throughout the present methodology, C. fetus was detected in the abomasal fluid samples of 2 bovine fetuses, being both identified as Cfv subspecies by PCR. Histopathological analyses demonstrated that macroscopic and microscopic changes found in the Cfv-positive animals were not either specific or directly related to Campylobacter infections. Moreover, no significant bacterial growth was observed in microbiological culture from the collected tissues, and both fetuses were negative for ruminant pestivirus. Differently, there was no detection of C. fetus in any of the analyzed ovine fetuses. Considering that abortion diagnosis rates reported in cattle and sheep industry are highly variable among the published studies, and that abortion diagnoses are commonly inconclusive due to difficulties in sampling methodology and inadequate identification of the pathogen involved, it is important to investigate the etiological causes of abortion the herds for better understanding the causes of pregnancy issues and monitoring their occurrence. In addition, the absence of pathognomonic lesions in the tissues investigated in the histopathological analyses observed in this study strongly suggests that well-known etiological agents commonly associated to abortion, such as Leptospira spp., Toxoplasma spp., Chlamydia spp. and Neospora caninum, are unlikely to be the cause of infection of the analyzed fetuses. Taking this into account, the presence of C. fetus in the abomasal fluid samples from two bovine fetuses demonstrated in the present study suggests the possible association of Cfv not only with infertility, but also with cases of bovine abortion, highlighting the importance of investigating unusual causal agents of abortions in sheep and cattle. Overall, an adequate diagnosis is essential for establishing better prevention strategies to avoid the circulation of abortion-related infectious agents in the herds.(AU)

ABSTRACT

La Hiperplasia Suprarrenal Congénita (HSRC) corresponde a un grupo de defectos genéticos en la síntesis de cortisol. El 95% de ellas son debidas al déficit de 21-hidroxilasa por lo que nos referiremos solo a esta deficiencia. La hiperplasia suprarrenal congénita clásica (HSRC-C) debuta en recién nacidos o lactantes con insuficiencia suprarrenal primaria, diferentes grados de hiperandrogenismo clínico en mujeres y puede coexistir con hipotensión, hiperkalemia e hiponatremia si hay un déficit clínico de aldosterona. El objetivo de este artículo es actualizar el conocimiento y enfoques sugeridos para el manejo de la HSRC-C desde el inicio de sus controles en la etapa adulta. El diagnóstico diferencial en retrospectiva de la HSRC-C y la no clásica (HSRC-NC) a veces resulta difícil ya que esta enfermedad es un espectro fenotípico continuo. La insuficiencia suprarrenal y la dependencia a terapia corticoidal son los eventos principales para diferenciar estas dos patologías que tienen enfoques terapéuticos diferentes. El tratamiento de la HSRC-C en adultos abarca 2 objetivos primarios: la adecuada sustitución de la falla suprarrenal y el control de hiperandrogenismo mediante el uso de corticoides en sus dosis mínimas efectivas. En la mujer existen terapias complementarias para el control del hiperandrogenismo como anticonceptivos y otras que se encuentran en diferentes fases de investigación. Esto permite disminuir las dosis de corticoides en algunos casos. Es importante a la vez abordar tres objetivos secundarios: controlar el riesgo cardiometabólico propio de la enfermedad, evitar el sobre tratamiento corticoidal y manejar la infertilidad. La correcta monitorización del tratamiento en adultos tomando en cuenta los objetivos descritos permite una mejor calidad de vida en estos pacientes. Finalmente el consejo genético debe realizarse en todos los pacientes con HSRC que deseen fertilidad y en sus parejas. El estudio requiere de secuenciación del gen CYP21A2 y debe realizarse en un laboratorio de experiencia.


Congenital Adrenal Hyperplasia (CAH) are a group of genetic defects characterized by impaired cortisol synthesis. 95% of them are due to 21-hydroxylase deficiency. We will discuss only this enzyme's deficiency. Classic congenital adrenal hyperplasia (CAH-C) debuts in newborns or infants with primary adrenal insufficiency, some degree of clinical hyperandrogenism in newborn females, and can coexist with hypotension, hyperkalemia, and hyponatremia if there is a clinical aldosterone deficiency. The objective of this article is to update the knowledge and suggested approaches for the management of CAH-C from the beginning of its controls in the adult stage. The retrospective differential diagnosis of CAH-C and non-classical (CAH-NC) is sometimes difficult because this disease is a continuous phenotypic spectrum. Adrenal insufficiency and dependence on corticosteroid therapy are the main events to differentiate these two pathologies that have different therapeutic approaches. In adults, the treatment of CAH-C must include 2 primary objectives: adequate the replacement of adrenal failure and control of hyperandrogenism, through the use of corticosteroids in their minimum effective doses. In women there are complementary therapies for the control of hyperandrogenism, such as contraceptives and others that are in different phases of research. This makes it possible to reduce the doses of corticosteroids in some cases. It is important at the same time to address three secondary objectives: control the cardiometabolic risk of the disease secondary to corticosteroid treatment, avoid corticosteroid overtreatment and manage infertility. The correct monitoring of treatment in adults and taking in to account the objectives described, allows a better quality of life in these patients. Finally, genetic counseling must be carried out in all patients planning for children, with any type of CAH and in their partners. The study requires sequencing of the CYP21A2 gene and must be performed in a certified laboratory.

ABSTRACT

Abstract Infertility is becoming a growing issue in almost all countries. Assisted Reproductive Technologies (ART) are recent development in treating infertility that give hope to the infertile couples. However, the pregnancy rates achieved with the aid of ART is considerably low, as success in ART is not only based on the treatment but also on many other controllable and uncontrollable biological, social, and environmental features. High expenditures and painful process of ART cycles are the two major barriers for opting for ART. Moreover, ART treatments are not covered by any health insurance schemes. Computational prediction models could be used to improve the success rate by predicting the treatment outcome, before the start of an ART cycle. This may suggest the couples and the doctors to decide on the next course of action i.e. either to opt for ART or opt for correcting determinants or quit the ART. With the intension to improve the success rate of ART by providing decision support system to the physicians as well to the patients before entering into the treatment this research work proposes a dynamic model for ART outcome prediction using Machine Learning (ML) techniques. The proposed dynamic model is partially implemented with the help of an ensemble of heterogeneous incremental classifier and its performance is compared with state-of-art classifiers such as Naïve Bayes (NB), Random Forest (RF), K-star etc.,using ART dataset. Performance of the model is evaluated with various metrics such as accuracy, Precision Recall Curve (PRC), Receiver Operating Characteristic (ROC), F-Measure etc., However, ROC cure area is taken as the chief metric. Evaluation results shows that the model achieves the performance with the ROC area value of 94.1 %.

ABSTRACT

La prolactina es una hormona hipofisiaria implicada en diversas funciones tales como reproductivas, lactancia y metabólicas. El hallazgo de hiperprolactinemia es frecuente en mujeres que consultan por infertilidad, oscilando entre el 15 y el 20%. Sus manifestaciones clínicas incluyen trastornos del ciclo, galactorrea, infertilidad y osteoporosis. Cuando hay tumores que superan 1 cm de diámetro pueden asociarse a alteraciones visuales. Aunque la hiperprolactinemia puede ser producida por el embarazo, el consumo de algunos fármacos, los trastornos tiroideos, las alteraciones hepáticas y renales, su causa más frecuente es la presencia de adenomas hipofisiarios productores de prolactina. Pueden ser microadenomas cuando su tamaño es menor de 10 mm y que representan el 90% o macroadenomas cuando son de mayor tamaño. La prolactina se encuentra bajo un estrecho control de su secreción a través de un sistema de retroalimentación de asa corta que hace que se libere dopamina que frena su producción. También se han descrito péptidos liberados de prolactina entre los que se encuentra la TRH. El exceso en su producción inhibe directamente la pulsatilidad de la GnRH y disminución en los pulsos de LH. Este cambio conduce a ciclos anovulatorios. Para su manejo se encuentran aprobados en Colombia fármacos agonistas de la dopamina como bromocriptina y cabergolina, siendo este último más efectivo. El manejo con cirugía transesfenoidal se reserva para aquellos casos en los que el tratamiento farmacológico ha fallado.


Prolactin is an hypophyseal hormone implicated in various functions such as reproductive, lactation and metabolic. Finding hyperprolactinemia is frequent in women consulting for infertility, ranging between 15 and 20%. Its clinical manifestations include menstrual cycle irregularities, galactorrhea, infertility and osteoporosis. When tumors greater than 1 cm in diameter are present visual disturbances may appear. Although hyperprolactinemia may be produced by pregnancy, certain medications, thyroid disfunction, hepatic or renal disfunction, the most frequent cause is the presence of prolactin secreting adenomas. They can be micro adenomas when their diameter is less than 10 mm, representing 90% or macro adenomas when their size is greater. Prolactin secretion is under a close control through a short loop feedback system, that makes dopamine to be secreted which lowers its production. Releasing peptides have been described, including TRH. Excess in its production directly inhibits GnRH pulsatility lowering LH pulses. This change conducts to anovulatory cicles, For its treatment in Colombia dopamine agonists have been approved, including bromocriptine and cabergoline, the last one being mor effective. Surgical management with transesphenoidal approach is reserved for those cases in which pharmacological treatment has failed.

ABSTRACT

Abstract Finasteride is a 5α-reductase enzyme inhibitor that has been approved for the treatment of male androgenic alopecia since 1997. Over time, it has been considered a safe and well-tolerated drug with rare and reversible side effects. Recently there have been reports of adverse drug-related reactions that persisted for at least three months after discontinuation of this drug, and the term post-finasteride syndrome arose. It includes persistent sexual, neuropsychiatric, and physical symptoms. Studies to date cannot refute or confirm this syndrome as a nosological entity. If it actually exists, it seems to occur in susceptible people, even if exposed to small doses and for short periods, and symptoms may persist for long periods. Based on currently available data, the use of 5α-reductase inhibitors in patients with a history of depression, sexual dysfunction, or infertility should be carefully and individually assessed.

ABSTRACT

Introdução: perdas gestacionais esporádicas são comuns e estima-se que aproximadamente 30 a 50% de todas as concepções não terminem em um recém-nascido vivo. Patologia materna ou alteração genética de natureza cromossômica, em um dos progenitores, são fatores de risco favoráveis a esses acontecimentos. Outras situações que podem estar relacionadas às alterações cromossômicas são a infertilidade e a ocorrência de mola hidatiforme (neoplasia trofoblástica gestacional), caracterizada por interferência na formação e desenvolvimento do embrião. Embora haja um consenso sobre o caráter multifatorial das perdas gestacionais, incluindo componentes anatômicos, imunológicos, endócrinos, genéticos e ambientais, ainda assim, a causalidade pode permanecer desconhecida. Objetivos: analisar e quantificar achados de dificuldades reprodutivas relacionados a presença de alterações cromossômicas encontrados no serviço de genética realizado pelo programa Genética & Sociedade, do Instituto de Biologia da Universidade Federal da Bahia. Metodologia: estudo descritivo e analítico, realizado por meio de consulta a fichas de anamneses, preenchidas durante o atendimento de casais, que buscaram o serviço de genética comunitária para aconselhamento genético no período de vinte anos. Resultados: entre os 73 casais selecionados para estudo, 59 (80,8%) relataram abortos recorrentes, 9 (12,3%) tinham histórico de mola hidatiforme e 5 (6,8%) apresentaram infertilidade. Entre as alterações foram verificadas translocações, inversões, além de polimorfismos de regiões heterocromáticas. Conclusões: o presente estudo confirma a importância das alterações cromossômicas na etiologia das dificuldades reprodutivas, justificando a busca pelo aconselhamento genético. Em termos de saúde pública, traz contribuições para o entendimento das condições genéticas da comunidade beneficiada pelo programa Genética & Sociedade.


Introduction: sporadic gestational losses are common, it's estimated that approximately 30 to 50% of all conceptions don't end in a newborn alive. Maternal pathology or genetic alterations of chromosomal nature in one of the progenitors are risk factors favorable to these events. Other situations that may be related to chromosomal alterations are infertility and the occurrence of hydatidiform mole (gestational trophoblastic neoplasia), characterized by interference in the formation and development of the embryo. Although there is a consensus about the multifactorial nature of gestational losses, including anatomical, immunological, endocrine, genetic and environmental components, however, the causality may remain unknown. Objectives: analyze and quantify the findings of reproductive difficulties related to the presence of chromosomal alterations found in the genetics service performed by the Genética&Sociedade program of the Biology Institute of the Federal University of Bahia. Methodology: a descriptive and analytical study, carried out by consultation of anamnesis records, made during the care of couples, who sought the community genetic service for genetic counseling in the period of twenty years. Results: among the 73 couples selected, 59 (80.8%) reported recurrent abortions, 9 (12.3%) had a history of hydatidiform mole and 5 (6.8%) had infertility. Among all the alterations, were found translocations, inversions, and polymorphisms of heterochromatic regions. Conclusions: this study confirms the importance of chromosomal alterations in the etiology of reproductive difficulties, justifying the search for genetic counseling. In terms of public health, it contributes to the understanding of the genetic conditions in the community benefited by the Genética&Sociedade program.

ABSTRACT

Background. Meta-analyses of the implementation of a surgical safety checklist (SSC) in observational studies have shown a significant decrease in mortality and surgical complications.Objective. To determine the efficacy of the SSC using data from randomised controlled trials (RCTs).Methods. This meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered with PROSPERO (CRD42015017546). A comprehensive search of six databases was conducted using the OvidSP search engine.Results. Four hundred and sixty-four citations revealed three eligible trials conducted in tertiary hospitals and a community hospital, with a total of 6 060 patients. All trials had allocation concealment bias and a lack of blinding of participants and personnel. A single trial that contributed 5 295 of the 6 060 patients to the meta-analysis had no detection, attrition or reporting biases. The SSC was associated with significantly decreased mortality (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.42 - 0.85; p=0.0004; I2=0%) and surgical complications (RR 0.64, 95% CI 0.57 - 0.71; p<0.00001; I2=0%). The efficacy of the SSC on specific surgical complications was as follows: respiratory complications RR 0.59, 95% CI 0.21 - 1.70; p=0.33, cardiac complications RR 0.74, 95% CI 0.28 - 1.95; p=0.54, infectious complications RR 0.61, 95% CI 0.29 - 1.27; p=0.18, and perioperative bleeding RR 0.36, 95% CI 0.23 - 0.56; p<0.00001.Conclusions. There is sufficient RCT evidence to suggest that SSCs decrease hospital mortality and surgical outcomes in tertiary and community hospitals. However, randomised evidence of the efficacy of the SSC at rural hospital level is absent
