RESUMO

OBJECTIVE: To evaluate clinical and laboratory outcomes of oocyte donation cycles and compare the results from donors and recipients. METHODS: A retrospective cohort study was conducted at a reproductive medicine center. A 586 first fresh oocyte donation cycles, performed from 01/2002 to 12/2017 were included. The outcomes of 290 cycles from donors and 296 from recipients, resulting in 473 fresh embryo transfers, were analyzed. The oocyte division was equally made, whereas, at an odd amount, the donor always had a preference. The data were collected from an electronic database, and analyzed using Chi-square test, Fisher's exact test, Mann-Whitney U-test or Student t-test depending on the data distribution, and multivariate logistic regression, considering p<0.05. RESULTS: The main results comparing donor and recipient, were, respectively: fertilization rate (72.0±21.4 vs. 74.6±24.2, p<0.001), implantation rate (46.2% vs. 48.5%, p=0.67); clinical pregnancy rate (41.9% vs. 37.7%, p=0.39), live birth rates by transfer (33.3 vs. 37.7, p=0.54). CONCLUSIONS: Oocyte donation is often the way donors can access in vitro fertilization, and for recipients seems to be a good option for pregnancy. Demographic and clinical characteristics have a secondary role in oocyte donors under 35 years and patient without comorbidities under 50 years and were not associated with pregnancy outcomes, emphasizing the power of oocyte quality on the success of intracytoplasmic sperm injection treatment. An oocyte-sharing program that offers good and comparable results is fair and worth being encouraged.

RESUMO

OBJECTIVE: Ectopic pregnancy is a well-known complication following in vitro fertilization with embryo transfer; studies have questioned, however, whether there are risk factors that could be identified before the procedure. The objective of this study was to investigate the possible risk factors involved in ectopic pregnancy following in vitro fertilization. METHODS: Retrospective case-control study performed at an assisted reproduction clinic in Brazil. To select the control group, we used a 1:4 ratio. The study included 499 patients submitted to in vitro fertilization with clinical pregnancy. We collected the data from electronic records, between 2000-2019 and divided into: Group 1, ectopic pregnancy (n=90) and Group 2, intrauterine pregnancies (n=409). RESULTS: When comparing groups, the results observed were: Tubal factor infertility (35.6% vs. 21.1%, p=.005) (OR 2.0 [1.2-3.4], p=.004); Previous miscarriage history (15.1% vs. 7.1%, p<.05) (OR 2.0 [1.02-4.29], p=.044); Number of cleavage-stage embryo transfers (69.2% vs. 54.0 p=.028) (OR 1.9 [1.08-3.33], p=.025); Two or more embryos transferred (OR 2.5 [1.12-5.70], p=.025), all associated with greater ectopic pregnancy risk. Oocyte recipient patients were excluded from this analysis, but when included a difference was found when comparing the groups (9.4% (10/106) vs. 3.0% (13/434), p=.007), (OR 3.3 [1.41-7.98] p=.005); this result should be interpreted with caution because of the sample size. CONCLUSIONS: In high-risk patients, a single blastocyst transfer seems to be a reasonable approach to decrease the ectopic pregnancy risk.

RESUMO

OBJECTIVE: Outcome data for oocyte vitrification for fertility preservation are still scarce despite the scientific and technological advances. Studies suggest that patients with cancer have worse outcomes regarding mature vitrified oocytes when compared to healthy patients. Thus, the objective of this study was to evaluate and compare the oocyte vitrification response in patients undergoing elective and oncofertility preservation. METHODS: The ovarian stimulation response was verified by a cross-sectional and observational study, analyzing data from 367 patients between 2009 and 2018, which were divided into elective group (EG; n=327) and oncofertility group (OFG; n=40). The number of follicles, oocytes, mature oocytes, and duration of the cycle was evaluated, which were compared with clinical and ovarian stimulus data between groups. RESULTS: A significant difference in women's age (31.3±5.8 vs. 37.0±2.9 years; p<0.01) and basal values of Follicle Stimulating Hormone (FSH), (4.0 [3.3 - 6.2] vs. 9.0 [5.4 - 9.9] mIU/mL; p<0.01) were observed. When adjusting data for age, FSH and Gonadotropin-releasing Hormone protocols, no significant difference in the number of vitrified mature oocytes between the two groups were observed (6.0 [3.0-11.0] vs. 7.0 [3.0-12.0]; p=0.11). CONCLUSIONS: Thus, patients undergoing elective and oncofertility preservation seem to respond similarly to controlled ovarian stimulation for fertility preservation. Breast cancer was the most frequent in the OFG (67%).

RESUMO

BACKGROUND: The increasing global use of smartphones has contributed to the growing use of apps for various health conditions, showing promising results. Through mobile apps, it is possible to perform chronological and iconographic follow-up of wounds, such as pressure ulcers, using a simple and practical tool. However, numerous surveys have pointed out issues related to the functionality, design, safety, and veracity of app information. OBJECTIVE: The objective of this study was to perform a systematic review of published studies regarding mobile apps and a systematic survey in app stores looking for apps developed to identify, evaluate, treat, and/or prevent pressure ulcers in adults, and to evaluate those apps based on software quality characteristics. METHODS: This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The main bibliographic databases were searched between January 1, 2007 and October 15, 2018, and an app survey was performed in app stores. The selected studies were evaluated according to software quality characteristics by the International Organization for Standardization/International Electrotechnical Commission (ie, ISO/IEC 25010:2011) that involve functionality, efficiency, compatibility, usability, reliability, safety, maintenance, and portability. RESULTS: The search in databases and web-based app stores returned a total of 2075 studies. After removal of duplicates and screening of titles and abstracts, 48 complete articles were evaluated for eligibility, and among these, six were included for qualitative synthesis. CONCLUSIONS: In this review, it was observed that all studies involved the initial phase of app development or improvement, and therefore, the apps still need to be evaluated using different software quality characteristics, so that in the future, a gold standard can be approached. Therefore, the prescription of an app for the identification, evaluation, treatment, and/or prevention of pressure ulcers in adults is currently limited. However, the evaluated studies provided important insights for future research. It is of utmost importance that future surveys develop apps jointly with users, using collaborative and cocreative processes and assess patients in real-world situations across different service settings, and they should consider different ethnicities, so that apps are useful to end users, such as patients, family members, health professionals, and students, in the health area. In addition, it is necessary for studies to describe the methodological course of app development in a clear and objective way in order to ensure reproducibility of the study and to offer inputs to allow future research to approach the development of ideal apps that are geared to positively impact the health of end users.

RESUMO

A síndrome de Turner decorre de uma anomalia dos cromossomos sexuais, afetando cerca de 1:2.500 nascidos vivos. A síndrome caracteriza-se principalmente por atraso do e denvolvimento dos caracteres sexuais e/ou amenorreia e baixa estatura. Entretanto, uma diversidade de estigmas também pode estar presente. O diagnóstico pode ser realizado com base nos estigmas da síndrome associados a um quadro de hipogonadismo hipergonadotrófico e confirmado por meio do cariótipo ­ sendo esse classicamente 45,X (monossomia do cromossomo X). Entretanto, os mosaicos (45,X/46,XY ou 45,X/46,XX) podem representar 34% a 75% dos casos, dependendo do método de análise utilizado. Trata-se de uma condição rara correspondendo a 5% das disgenesia gonadais e apresenta um amplo espectro fenotípico. A importância da identificação de mosaicos, especialmente a presença do cromossomo Y, reside no manejo adequado da gônada disgenética para a prevenção da ocorrência de tumor gonadal, principalmente o gonadoblastoma, com considerável potencial maligno.(AU)


Turner's syndrome results from a sex chromosomes anomaly, affecting about 1:2,500 live births. The syndrome is characterized mainly by delayed development of sexual characteristics and/or amenorrhea and short stature. However, a variety of stigmas may also be presented. The diagnosis can be made based on the stigmas of the syndrome associated with a hypergonadotrophic hypogonadism and confirmed by the karyotype ­ this being classically 45, X (monosomy of the X chromosome). However, mosaics (45,X/46,XY or 45,X/46, XX) may represent 34% to 75% of cases depending on the method of analysis used. It is a rare condition, corresponding to 5% of gonadal dysgenesis and presents a broad phenotypic spectrum. The importance of mosaic identification, especially the presence of the Y chromosome, lies in the proper management of the dysgenetic gonad for the prevention of the occurrence of gonadal tumor, especially gonadoblastoma, with considerable malignant potential.(AU)
