RESUMO
The objective of this study was to investigate the effects of low-dose hCG supplementation on ICSI outcomes and controlled ovarian stimulation (COS) cost. Three hundred and thirty patients undergoing ICSI were split into groups according to the COS protocol: (i) control group (n = 178), including patients undergoing conventional COS treatment; and (ii) low-dose hCG group (n = 152), including patients undergoing COS with low-dose hCG supplementation. Lower mean total doses of FSH administered and higher mean oestradiol level and mature oocyte rates were observed in the low-dose hCG group. A significantly higher fertilization rate, high-quality embryo rate and blastocyst formation rate were observed in the low-dose hCG group as compared to the control group. The miscarriage rate was significantly higher in the control group compared to the low-dose hCG group. A significantly lower incidence of OHSS was observed in the low-dose hCG group. There was also a significantly lower gonadotropin cost in the low-dose hCG group as compared to the control group ($1235.0 ± 239.0×$1763.0 ± 405.3, p < 0.001). The concomitant use of low-dose hCG and FSH results in a lower abortion rate and increased number of mature oocytes retrieved, as well as improved oocyte quality, embryo quality and blastocyst formation and reduced FSH requirements.

A Esclerose Lateral Amiotrófica (ELA) é uma doença neurodegenerativa do sistema nervoso central (SNC) que acomete tanto o neurônio motor superior (NMS) quanto o neurônio motor inferior (NMI), causando fraqueza e diminuição progressiva das habilidades funcionais. Entre os profissionais de saúde existe um déficit de informações sobre os objetivos e benefícios da fisioterapia nesta população. O objetivo deste estudo foi identificar os resultados da fisioterapia neurofuncional em pacientes com ELA. Realizou-se uma busca nas bases de dados Medline, Lilacs, SciELO, IBECS e PEDro, utilizando os seguintes descritores: esclerose lateral amiotrófica, espasticidade, força muscular, fadiga, fisioterapia, reabilitação, exercício e qualidade de vida. A busca resultou em dois artigos que tiveram seus resultados analisados, os dois avaliaram os resultados de um programa de exercícios domiciliares de intensidade moderada, associados ou não a outra conduta terapêutica. Os estudos encontrados apontaram menor deterioração na ALS Functional Rating Scale, e diminuição da espasticidade. Em conclusão, a fisioterapia neurofuncional mostrouse eficaz na manutenção da funcionalidade de pacientes com ELA por tempo mais prolongado.
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder of the central nervous system that affects both the upper and lower motor neurons, causing weakness and a progressive decrease in functional skills. Among health professionals, there is a lack of information on the objectives and benefits of physical therapy in this population. The objective of this study was to identify the results of neurofunctional physical therapy in patients with ALS. A search of the Medline, Lilacs, SciELO, IBECS, and PEDro databases was performed by using the following keywords: "amyotrophic lateral sclerosis", "spasticity", "muscle strength", "fatigue", "physical therapy", "rehabilitation", "exercise", and "quality of life". The search led to analyze the results of two articles reviewing the data obtained from a moderate intensity home exercises program that was or was not associated with another therapeutic approach. The studies found showed less deterioration, according to the ALS Functional Rating Scale and decreased spasticity. In conclusion, neurofunctional physical therapy was shown to be effective in maintaining the functionality of patients with ALS for longer periods.

Objective The aim of this study was to study the effects of Tribulus terrestris on sexual function in menopausal women. Methods This was a prospective, randomized, double-blind, placebo-controlled clinical trial that included 60 postmenopausal women with sexual dysfunction. The women were divided into two groups, placebo group and Tribulus group, and evaluated by using the Sexual Quotient-female version (SQ-F) and Female Intervention Efficacy Index (FIEI) questionnaires. Results There was no significant difference between the groups in age, age at menopause, civil status, race, and religion. In the evaluation with the SQ-F questionnaire, there were significant differences between the placebo (7.6±3.2) and Tribulus (10.2±3.2) groups in the domains of desire and sexual interest (p d" 0.001), foreplay (3.3±1.5 versus 4.2±1.0) (p d" 0.01), arousal and harmonious interaction with the partner (5.7±2.1 versus 7.2±2.6) (p d" 0.01), and comfort in sexual intercourse (6.5±2.4 versus 8.0±1.9) (p d" 0.01). There was no significant difference between the placebo and Tribulus groups in the domains of orgasm and sexual satisfaction (p = 0.28). In the FIEI questionnaire, there was a significant improvement (p < 0.001) in the domains of vaginal lubrication during coitus and/or foreplay (20 versus 83.3%), sensation in the genitalia during sexual intercourse or other stimuli (16.7 versus 76.7%), sensation in the genital region (20 versus 70%), sexual intercourse and/or other sexual stimulations (13.3 versus 43.3%), and the ability to reach orgasm (20% versus 73.3%). There was no significant difference in adverse effects between the two groups. Conclusions After 90 days of treatment, at the doses used, we found Tribulus terrestris to be effective in treating sexual problems among menopausal women.

In order to increase the success rate of in vitro fertilization cycles, several studies have focused on the identification of the embryo with higher implantation potential. Despite recent advances in the reproductive medicine, based on the OMICs technology, routinely applicable methodologies are still needed. Thus, in most fertilization centers embryo selection for transfer is still based on morphological parameters evaluated under light microscopy. Several morphological parameters may be evaluated, ranging from the pronuclear to blastocyst stage. In general, despite the day of transfer, some criteria are suggested to present a predictive value for embryo viability when analyzed independently or combined. However, the subjectivity of morphological evaluation, as well as the wide diversity of embryo classification systems used by different fertilization centers shows contrasting results, making the implementation of a consensus regarding different morphological criteria and their predictive value a difficult task. The optimization of embryo selection represents a large potential to increase treatment success rates, allowing the transfer of a reduced number of embryos and minimizing the risks of multiple pregnancy.

Com o objetivo de aumentar as taxas de sucesso das pacientes que são submetidas a técnicas de reprodução humana assistida (RHA), numerosos estudos apresentam como foco a identificação do embrião com maior potencial de implantação. Apesar dos avanços tecnológicos significativos da Medicina Reprodutiva baseados no advento da era da genômica, proteômica e metabolômica (OMICS), técnicas rotineiramente aplicáveis ainda não estão disponíveis. Dessa forma, laboratórios de fertilização in vitro(FIV) de todo o mundo selecionam para transferência embriões humanos cultivados in vitrobaseados em parâmetros morfológicos avaliados em microscopia de luz. Diversos parâmetros morfológicos podem ser avaliados desde o estágio pronuclear até o estágio de blastocisto para embriões humanos cultivados in vitro. De modo geral, independentemente do dia da transferência, tais critérios parecem apresentar valor preditivo de viabilidade embrionária quando avaliados individualmente ou coletivamente. No entanto, a subjetividade da avaliação morfológica, bem como a ampla diversidade de sistemas de classificação embrionária aplicados por diferentes clínicas, implica em resultados contraditórios, tornando extremamente difícil a implementação de um consenso do valor preditivo dos diferentes parâmetros morfológicos avaliados. A otimização da seleção embrionária representa um grande potencial de aumento das taxas de sucesso do tratamento, além de possibilitar a realização da transferência de um número reduzido de embriões, minimizando os riscos derivados de estações múltiplas.

OBJECTIVE: To evaluate if ICSI outcome are influenced by the number of cycles and oocyte injected per day. METHODS: Data of ICSI cycles performed in an unselected infertile population were included. The influences of the number of cycles and number of injected oocytes on the ICSI outcomes (fertilization rate, high quality embryos rates on day 3 of development, blastocyst formation rate, the proportion of cycles with embryo transfer, pregnancy rate and implantation rate) were investigated. RESULTS: Regression analyses results showed no significant influence of the number of cycles and oocytes injected per day on the ICSI outcomes. CONCLUSION: The outcomes of ICSI are not influenced by the number of cycles or the number of oocytes injected per day. We suggest that an appropriate number of embryologists per cases per year guarantee successful outcomes independently of the daily workload.
RESUMO
OBJECTIVE: To compare ethylenediamine tetraacetic acid (EDTA) tubes and plasma preparation tubes (PPT) for evaluating maternal plasma during the first trimester of pregnancy. METHODS: A cross-sectional study was conducted on 24 male fetuses in women between 6 and 14 weeks of pregnancy. Blood samples (10 mL) were collected and stored in EDTA and PPT tubes. Subsequently, the samples were centrifuged and sent for free fetal DNA extraction by means of the polymerase chain reaction (PCR) technique. The reactions were performed in a real time PCR machine for detecting the amplification products. The genome region chosen for performing the PCR reactions was a target specific for the Y chromosome, in which the DYS-14 marker was amplified only when the DNA was of male sex. The free fetal DNA concentration was given by the threshold cycle (TC). To compare the tubes, the paired Student t-test was used. RESULTS: The mean gestational age was 11.08 ± 2.30 weeks (range: 6-14). The mean TC for PPT was 30.08 ± 1.05 (range: 27.08-32.61) and for EDTA, 30.23 ± 0.96 (range: 28.01-32.09), but without statistical significance (p=0.357). CONCLUSION: We did not observe any statistically significant difference in free fetal DNA concentration between the EDTA and PPT tubes.

The aim of this study was to investigate the association between MTHFR gene polymorphisms and IVF outcomes in Brazilian women undergoing assisted reproduction treatment. A prospective study was conducted in the Human Reproduction Department at the ABC University School of Medicine and the Ideia Fertility Institute between December 2010 and April 2012. The patient population was 82 women undergoing assisted reproduction cycles. The MTHFR polymorphisms C677T and A1298C were evaluated and compared with laboratory results and pregnancy rates. The C677T variant was associated with proportions of mature (P=0.006) and immature (P=0.003) oocytes whereas the A1298C variant was associated with number of oocytes retrieved (P=0.044). The polymorphisms, whether alone or in combination, were not associated with normal fertilization, good-quality embryo or clinical pregnancy rates. This study suggests that the number and maturity of oocytes retrieved may be related to the MTHFR polymorphisms C677T and A1298C. It is believed that folate has a crucial function in human reproduction and that folate deficiency can compromise the function of the metabolic pathways it is involved in, leading to an accumulation of homocysteine. The gene MTHFR encodes the 5-MTHFR enzyme, which is involved in folate metabolism, and C677T/A1298C polymorphisms of this gene are related to decreased enzyme activity and consequent changes in homocysteine concentration. Folate deficiency and hyperhomocysteinaemia can also compromise fertility and lead to pregnancy complications by affecting the development of oocytes, preparation of endometrial receptivity, implantation of the embryo and pregnancy. In folliculogenesis, hyperhomocysteinaemia can activate apoptosis, leading to follicular atresia and affecting the maturity of oocytes and the quality of embryos cultured in vitro. This study was performed to investigate the association between MTHFR polymorphisms and IVF outcomes in women undergoing assisted reproduction treatment.

Since endometriosis is a proliferative disease we evaluated the presence of anti-apoptotic factor (Bcl-2) and pro-apoptotic factor (Bax) in deep pelvic endometriosis. A Cross-sectional observational study was performed at Santa Casa de Misericórdia de São Paulo, São Paulo, Brazil. Forty women aged 26 to 46 years with deep endometriosis were selected. They had not been clinically treated for at least 3 months prior to surgery and then underwent surgical laparoscopy to treat the disease. During the surgery, tissue was collected from the uterosacral ligaments and the rectosigmoid; an endometrial biopsy was also performed as a control. All interventions were performed by the same surgeon. The specimens were sent for pathological and immunohistochemical analyses; endometriosis was confirmed in all patients. After the immunohistochemical reaction a semi-quantitative evaluation of the staining intensity (relative optical density-ROD) was conducted, applying the digital densitometric analysis system. In the uterosacral ligaments 97.5% of the specimens were positive for Bcl2 whereas in the rectosigmoid 100% were positive. In the endometrium we observed that 87.5% were positive for Bcl2. BAX expression was null in the rectosigmoid and in the endometrium. In the uterosacral ligaments 2.5% of the specimens expressed BAX. The relative optical density of Bcl2 was higher in the rectosigmoid and in the uterosacral ligament when compared to the endometrium, 0.141±0.002; 0.129±0.001, respectively (p<0.01). We concluded that the anti-apoptotic factor Bcl-2 was expressed in all studied specimens, but in a higher staining intensity in the rectosigmoid and in the uterossacral ligaments in comparison to the endometrium. The pro-apoptotic factor Bax had virtually no expression in the studied tissues.
