RESUMO

BACKGROUND: Feedback is an essential tool for learning and improving performance in any sphere of education, including training of resident physicians. The learner's perception of the feedback they receive is extremely relevant to their learning progress, which must aim at providing qualified care for patients. Studies pertinent to the matter differ substantially with respect to methodology, population, context, and objective, which makes it even more difficult to achieve a clear understanding of the topic. A scoping review on this theme will unequivocally enhance and organize what is already known. OBJECTIVE: The aim of this study is to identify and map out data from studies that report surgical residents' perception of the feedback received during their education. METHODS: The review will consider studies on the feedback perception of resident physicians of any surgical specialty and age group, attending any year of residency, regardless of the type of feedback given and the way the perceptions were measured. Primary studies published in English, Spanish, and Portuguese since 2017 will be considered. The search will be carried out in 6 databases and reference lists will also be searched for additional studies. Duplicates will be removed, and 2 independent reviewers will screen the selected studies' titles, abstracts, and full texts. Data extraction will be performed through a tool developed by the researchers. Descriptive statistics and qualitative analysis (content analysis) will be used to analyze the data. A summary of the results will be presented in the form of diagrams, narratives, and tables. RESULTS: The findings of this scoping review were submitted to an indexed journal in July 2024, currently awaiting reviewer approval. The search was executed on March 15, 2024, and resulted in 588 articles. After the exclusion of the duplicate articles and those that did not meet the eligibility criteria as well as the inclusion of articles through a manual search, 13 articles were included in the review. CONCLUSIONS: Conducting a scoping review is the best way to map what is known about a subject. By focusing on the feedback perception more than the feedback itself, the results of this study will surely contribute to gaining a deeper understanding of how to proceed to enhance internal feedback and surgical residents' learning progress.

RESUMO

OBJECTIVE: Follicle-stimulating hormone (FSH) is essential for folliculogenesis, acting through the follicle-stimulating hormone receptor (FSHR) that is present on the membrane of granulosa cells. Polymorphisms in the FSHR gene may lead to an altered pattern of receptor expression on the cell surface or to changes in affinity for FSH. The aim of this prospective study was to detect any association between the follicle-stimulating hormone receptor (FSHR) gene Ala307Thr polymorphism (rs6165) and ovarian reserve, ovarian response or clinical results in IVF/ICSI treatment. METHODS: This prospective cohort study included 450 women who underwent IVF/ICSI cycles. DNA was extracted from peripheral blood, and the Ala307Thr FSHR polymorphism (rs6165) was genotyped using the TaqMan SNP genotyping assay. Participants were divided into three groups according to their Ala307Thr FSHR genotype: Thr/Thr (n:141), Thr/Ala (n=213) and Ala/Ala (n=96). The results were tested for associations with age, anti-Mullerian hormone (AMH) levels, antral follicle count (AFC), total dose of r-FSH, follicle size, number of retrieved oocytes, and clinical outcome of IVF/ICSI cycles. The statistical analyses were performed using Fisher's exact test and the Kruskal‒Wallis test. RESULTS: An association between the genotype of the FSHR (Ala307Thr) polymorphism and the dose of r-FSH was observed. Patients with the Ala/Ala genotype received a higher r-FSH dose than patients with the Ala/Thr (p=0.0002) and Thr/Thr (p=0.02) genotypes. No other correlation was observed. CONCLUSION: The Ala/Ala genotype was associated with the use of higher doses of recombinant FSH (r-FSH), suggesting that homozygosis of this allelic variant (Ala) provides lower sensitivity to r-FSH.

RESUMO

OBJECTIVE: To understand which of the controlled ovarian stimulation (COS) protocols used in different patients are associated with greater amounts of oocytes retrieved. METHODS: The study population was divided into three groups, considering AMH and AFC to obtain the Ovarian Response Predictor Index (ORPI); they were grouped into: G1-Low Reserve (ORPI <0.5); G2-Normal Reserve (ORPI:0.5-0.9); and G3-High Reserve (ORPI≥0.9). 246 cycles were selected in which COS was used: recombinant FSH - follitropin alfa or beta (Protocol 1) or corifollitropin alfa (Protocol 2), both associated with urinary HMG and the GnRH antagonist, with the trigger performed using recombinant hCG or GnRH agonist. RESULTS: The number of oocytes obtained was higher in protocol 1 in all groups, with higher counts seen in G1 than in G2 or G3. The number of days required in COS for protocol 2 was greater than for protocol 1 in all groups. The total dose of recombinant FSH alfa or beta / urinary HMG used in protocol 1 was inversely proportional to the ovarian reserve. The lower the ORPI, the greater the average number of international units administered. In protocol 2, there was a need to supplement with higher doses of urinary HMG when compared to protocol 1. The dosage of the GnRH antagonist was dependent on the number of COS days until the trigger was used. In obtaining MII oocytes, the percentages were similar regardless of the trigger used. CONCLUSIONS: The use of follitropin leads to greater numbers of retrieved oocytes than corifollitropin alfa in all ORPIs. The dose of recombinant FSH used with urinary HMG increases inversely proportional to the ORPI value. The fixed dose of recombinant FSH deposit requires a sharp increase in the dose of urinary HMG.

RESUMO

The association of Zika virus infection (ZIKV) with congenital malformation and neurological sequelae brought a significant global concern. Recent studies have shown that maternal viral infection leads to inflammation in the placental tissue. In this context, the antiinflammatory protein annexin 1 (ANXA1) has a major determination of the resolution of inflammation and it has been positively associated with antiparasitic activity in infected placental explants. Although these effects have been explored to some degree, ANXA1 expression and potential properties have not yet been fully elucidated in placentas infected with ZIKV. This study was conducted to evaluate the histopathology, inflammatory process and elucidate if ANXA1 were differently expressed in placentas of ZIKV-infected mothers. Three classification groups were used in this study: Neg/Neg (mother and placenta negative for the virus), Pos/Neg (infected mother, but no virus detected in placenta) and Pos/Pos (mother and placenta infected with ZIKV). ANXA1 was expressed in syncytiotrophoblast cells of all studied groups, and its expression was decreased in Pos/Neg group, which displayed also an increase of the inflammatory response, as evinced from the recruitment of inflammatory cells, increased levels of placenta cytokines, and evidence of impaired tissue repair. The presence of ZIKV in placentas of Pos/Pos group shows structural alterations, including detachment and disorganization of the trophoblastic epithelium. In summary, our results suggest that maternal infection with ZIKV, even without direct tissue infection, leads to a placental inflammatory response probably related to the modulation of ANXA1. After placental infection, structural changes - including inflammatory cells influx - are observed leading to placental dysfunction and reduced fetal weight. Our study sheds additional light on the outcomes of ZIKV infection in trophoblast and reveals a potential involvement of ANXA1 in the placental biology.

RESUMO

Zika virus (ZIKV) is a flavivirus that has been highly correlated with the development of neurological disorders and other malformations in newborns and stillborn fetuses after congenital infection. This association is supported by the presence of ZIKV in the fetal brain and amniotic fluid, and findings suggest that infection of the placental barrier is a critical step for fetal ZIKV infection in utero. Therefore, relevant models to investigate the interaction between ZIKV and placental tissues are essential for understanding the pathogenesis of Zika syndrome. In this report, we demonstrate that explant tissue from full-term human placentas sustains a productive ZIKV infection, though the results depend on the strain. Viral infection was found to be associated with pro-inflammatory cytokine expression and apoptosis of the infected tissue, and these findings confirm that placental explants are targets of ZIKV replication. We propose that human placental explants are useful as a model for studying ZIKV infection ex vivo.

RESUMO

ABSTRACT Objective: To describe our initial experience with a novel approach to follow-up and treat gastroschisis in "zero minute" using the EXITlike procedure. Methods: Eleven fetuses with prenatal diagnosis of gastroschisis were evaluated. The Svetliza Reductibility Index was used to prospectively evaluate five cases, and six cases were used as historical controls. The Svetliza Reductibility Index consisted in dividing the real abdominal wall defect diameter by the larger intestinal loop to be fitted in such space. The EXIT-like procedure consists in planned cesarean section, fetal analgesia and return of the herniated viscera to the abdominal cavity before the baby can fill the intestines with air. No general anesthesia or uterine relaxation is needed. Exteriorized viscera reduction is performed while umbilical cord circulation is maintained. Results: Four of the five cases were performed with the EXIT-like procedure. Successful complete closure was achieved in three infants. The other cases were planned deliveries at term and treated by construction of a Silo. The average time to return the viscera in EXIT-like Group was 5.0 minutes, and, in all cases, oximetry was maintained within normal ranges. In the perinatal period, there were significant statistical differences in ventilation days required (p = 0.0169), duration of parenteral nutrition (p=0.0104) and duration of enteral feed (p=0.0294). Conclusion: The Svetliza Reductibility Index and EXIT-like procedure could be new options to follow and treat gastroschisis, with significantly improved neonatal outcome in our unit. Further randomized studies are needed to evaluate this novel approach.


RESUMO Objetivo: Descrever a experiência inicial com a nova técnica cirúrgica EXIT-like para acompanhamento e correção de gastrosquise no "minuto zero". Métodos: Foram avaliados onze fetos com diagnóstico pré-natal de gastrosquise. O Svetliza Reducibility Index foi usado prospectivamente para avaliar cinco casos, e seis foram utilizados como controles. O índice foi calculado dividindo-se o diâmetro do defeito da parede abdominal pela maior alça intestinal que coubesse neste espaço. O procedimento EXIT-like compreendeu cesárea programada, analgesia fetal e redução da víscera herniada para a cavidade abdominal, antes da deglutição de ar pelo recém- nascido. Não são necessários anestesia geral e nem relaxamento uterino. A redução da víscera exteriorizada é realizada enquanto se mantém a circulação do cordão umbilical. Resultados: Quatro casos, dos cinco, foram submetidos ao EXIT-like. A correção foi completa em três casos. Os demais casos foram partos a termo planejados, e a correção do defeito foi feita com Silo. O tempo médio de redução da víscera foi de 5,0 minutos no grupo submetido ao procedimento EXITlike, e a oximetria foi mantida dentro dos valores de variação normal em todos os casos. No período perinatal, foram observadas diferenças estatisticamente significativas no tempo de ventilação mecânica (p=0,0169), duração da nutrição parenteral (p = 0,0104) e da nutrição enteral (p=0,0294). Conclusão: O Svetliza Reducibility Index e o procedimento EXIT-like podem ser novas opções para acompanhar e tratar gastroquise, com desfecho neonatal significativamente melhor em nossa unidade. Novos estudos randomizados são necessários para avaliar esta nova abordagem.

RESUMO

During the 2016 Zika virus outbreak in Brazil, we detected Zika virus RNA in urine samples collected from Zika virus-positive pregnant women during different stages of pregnancy. Women had positive and negative intervals of viruria; 3 newborns had adverse outcomes. Further research is needed to clarify the relationship between viruria and outcomes for newborns.

RESUMO

Purpose To identify which methods used in the assessment of the ovarian reserve are exclusive or complementary to identify the best response to follicle development. Methods Retrospective cohort study, involving patients undergoing assisted reproduction treatment at the Instituto de Medicina Reprodutiva e Fetal, from April 2009 to July 2014. Age, biochemical tests, and ultrasound were assessed. The data were analyzed to predict the follicular development and the relation between them, using, for statistical analysis, Statistical Package for Social Sciences software. Results Out of the 293 couples included, 50.2% presented infertility by ovarian factor. Considering the age as the main variable, a significant negative correlation with the volume of both ovaries was observed (right ovary, r = 0.21; left ovary, r = -0.22; both p < 0.0001), and with the antral follicle count (right ovary, r = -0.38; left ovary, r = -0.47; both p < 0.0001). Considering the antral follicle count as the main variable, a significant positive correlation with the total recruited oocytes was observed. When we correlated the antral follicle count with the recruited follicles larger than 18 mm, we observed that, with a cutoff of 12 antral follicles, there is a positive predictive value of 99%, and an area under the ROC curve of 0.76. Conclusion We concluded from our study that age and antral follicle count are effective predictors of ovarian response in cycles of assisted reproduction. The ovarian volume, as well as the anti-Müllerian hormone dosage, seem to be adequate markers of the ovarian reserve.

Resumo Objetivo Identificar quais métodos utilizados na avaliação da reserva ovariana são excludentes ou complementares na identificação da melhor resposta ao desenvolvimento folicular. Métodos Estudo retrospectivo de coorte, que envolveu pacientes em tratamento de reprodução assistida no Instituto de Medicina Reprodutiva de abril de 2009 a julho de 2014. Foram avaliadas idade, exames bioquímicos e ecografia. Os dados foram analisados na predição do desenvolvimento folicular e nas suas relações entre si, utilizando para análise estatística o programa Statistical Package for Social Sciences. Resultados Dos 293 casais incluídos, 50,2% apresentavam infertilidade por fator ovariano. Considerando a idade como principal variável, foi observada uma correlação significativa e negativa com volume de ambos ovários (ovário direito, r = 0,21; ovário esquerdo, r =0,22; ambos p< 0,0001), e com contagem de folículos antrais (ovário direito, r =0,38; ovário esquerdo, r =0,47; ambos p< 0,0001). Considerando a contagem de folículos antrais como a variável principal, foi observada uma correlação significativa e positiva com o total de oócitos recrutados. Quando correlacionamos a contagem de folículos antrais com os folículos recrutados maiores do que 18 mm, observamos que, com um ponto de corte de 12 folículos antrais, tem-se um valor preditivo positivo de 99%, e uma área da curva ROC de 0,76. Conclusões Concluímos com nosso trabalho que a idade e a contagem de folículos antrais são eficientes preditores da resposta ovariana em ciclos de reprodução assistida. O volume ovariano, assim como a dosagem do hormônio anti-mulleriano, parecem ser marcadores adequados de reserva ovariana.

RESUMO

ABSTRACT: CONTEXT: Umbilical cord thrombosis is related to greater fetal and perinatal morbidity and mortality. It is usually associated with umbilical cord abnormalities that lead to mechanical compression with consequent vascular ectasia. Its correct diagnosis and clinical management remains a challenge that has not yet been resolved. CASE REPORT: This study reports a case of umbilical artery thrombosis that occurred in the second half of a pregnancy. The umbilical cord was long, thin and overly twisted and the fetus presented severe intrauterine growth restriction. The clinical and histopathological findings from this case are described. CONCLUSIONS: This case report emphasizes the difficulty in diagnosing and clinically managing abnormalities of intrauterine life with a high chance of perinatal complications.

RESUMO

Gestational Toxoplasma gondii infection is considered a major risk factor for miscarriage, prematurity and low birth weight in animals. However, studies focusing on this topic in humans are scarce. The objective of this study is to determine whether anti-Toxoplasma gondii maternal serum profiles correlate prematurity and low birth weight in humans. The study examined 213 pregnant women seen at the High-Risk Pregnancy Hospital de Base, São José do Rio Preto, São Paulo, Brazil. All serological profiles (IgM-/IgG+; IgM-/IgG-; IgM+/IgG+) were determined by ELISA commercial kits. Maternal age, gestational age and weight of the newborn at birth were collected and recorded in the Statement of Live Birth. Prematurity was defined as gestational age <37 weeks and low birth weight ≤ 2499 grams. The t-test was used to compare values (p < 0.05). The mean maternal age was 27.6±6.6 years. Overall, 56.3% (120/213) of the women studied were IgM-/IgG+, 36.2% (77/213) were IgM-/IgG- and 7.5% (16/213) were IgM+/IgG+. The average age of the women with serological profile IgM+/IgG+ (22.3±3.9 years) was different from women with the profile IgM-/IgG+ (27.9±6.7 years, p = 0.0011) and IgM-/IgG- (27.9±6.4 years, p = 0.0012). There was no statistically significant difference between the different serological profiles in relation to prematurity (p = 0.6742) and low birth weight (p = 0.7186). The results showed that prematurity and low birth weight did not correlate with anti-Toxoplasma gondii maternal serum profiles.

RESUMO

Aims: To determine the frequency of anti-cardiolipin antibodies (aCL) in women with previous history of recurrent spontaneous abortion (RSA).Methods: Medical records from pregnant women seen from April 2005 to December 2008 at the High-Risk Pregnancy Unit at the Hospital de Base from FUNFARME (Fundação Faculdade Regional de Medicina), in São José do Rio Preto, São Paulo, Brazil, were revised. Patients olderthan 18 years who had at least two spontaneous abortions and who were tested for aCL wereincluded in the study. Data on maternal age, number of miscarriages and the results of serological tests for aCL were recorded. The exact Fisher's test was used to compare the results. A p value less than 0.05 was considered significant.Results: During the study period a total of 294 pregnant women were seen, from whom 44 consecutive women fulfilled the inclusion criteria. The overall mean age was 33.8±5.4 years (range: 22 to 44; median: 34). Eighteen (40.9%) patients were reagent for aCL and 26 (59.1%) non-reagent,and the difference between their mean age was not statistically significant (reagent: 34.6±5.8 years; non reagent: 33.2±5.2 years, p=0.4001). Fourteen (77.8%) patients presented IgM aCL and six (33.2%), IgG aCL. Two patients (11%) were reagent for both IgM and IgG aCL. In the most of cases the aCL antibody titers were compatible with low risk for pregnancy morbidity. The number of abortions ranged from two to six. The average number of abortions among those reagent for aCL was 3.5±1.1 and in those non-reagent was 2.9±1.1 (p=0.0813). Conclusions: The frequency of aCL was elevated among patients with a history of RSA,especially those having higher number of fetal losses. Among women with at least two spontaneousabortions, the mean number of abortions was not significantly different between those reagent for aCL and those non reagent.


Objetivos: Avaliar a frequência de anticorpos anticardiolipina (aCL) em mulheres comhistória prévia de aborto espontâneo recorrente (AER).Métodos: No período de abril de 2005 a dezembro de 2008 foram avaliados os dados deprontuários de gestantes atendidas no Ambulatório de Gestação de Alto Risco do Hospital de Baseda Fundação Faculdade Regional de Medicina (FUNFARME), em São José do Rio Preto, SãoPaulo, Brasil. Foram incluídas neste estudo pacientes com idade acima de 18 anos que tiveram pelomenos dois abortos espontâneos e foram avaliadas para aCL. O teste exato de Fisher foi usado paracomparar os resultados. Valor de p menor que 0,05 foi considerado significante.Resultados: Um total de 294 mulheres gestantes foram avaliadas durante o período doestudo, das quais 44 atendiam aos critérios de inclusão. A média de idade foi 33,8±5,4 anos(variação: 22 a 44; mediana: 34). Dezoito pacientes (40,9%) foram reagentes para aCL e 26 (59,1%)não reagentes, e a diferença entre a média de idade não foi estatisticamente significante (reagentes:34,6±5,8 anos; não reagentes: 33,2±5,2 anos, p=0,4001). Quatorze (77,8%) pacientes apresentaramaCL IgM e seis (33,2%) aCL IgG. Duas pacientes (11%) foram reagentes para ambas as classes deaCL, IgM e IgG. Na maioria dos casos os títulos de anticorpos aCL foram compatíveis com baixorisco para morbidade na gravidez. O número de abortos variou de dois a seis. O número médio deabortos entre as reagentes para aCL foi de 3,5±1,1 e entre as não reagentes foi de 2,9±1,1(p=0,0813).Conclusões: A frequência de aCL foi alta entre as pacientes com história de AER,especialmente entre aquelas que tiveram um maior número de perdas fetais. Entre as mulheres compelo menos dois abortos espontâneos, a média do número de abortos não foi significativamentediferente entre aquelas reagentes e não reagentes para aCL.

RESUMO

OBJECTIVE: To assess the quality of images and video clips of fetal central nervous (CNS) structures obtained by ultrasound and transmitted via tele-ultrasound from Brazil to Australia. METHODS: In this cross-sectional study, 15 normal singleton pregnant women between 20 and 26 weeks were selected. Fetal CNS structures were obtained by images and video clips. The exams were transmitted in real-time using a broadband internet and an inexpensive video streaming device. Four blinded examiners evaluated the quality of the exams using the Likert scale. We calculated the mean, standard deviation, mean difference, and p values were obtained from paired t tests. RESULTS: The quality of the original video clips was slightly better than that observed by the transmitted video clips; mean difference considering all observers = 0.23 points. In 47/60 comparisons (78.3%; 95% CI = 66.4-86.9%) the quality of the video clips were judged to be the same. In 182/240 still images (75.8%; 95% CI = 70.0-80.8%) the scores of transmitted image were considered the same as the original. CONCLUSION: We demonstrated that long distance tele-ultrasound transmission of fetal CNS structures using an inexpensive video streaming device provided images of subjective good quality.

RESUMO

PURPOSE: To evaluate the sonographic parameters related to morphological characteristics of pelvic adnexal masses by obtaining two-dimensional images by an observer presence, forwarded electronically (via tele-ultrasound) in static and dynamic modes observers do not face (distance) for comparative analyzes inter intraobserver and to the validation of a second opinion. METHODS: From March to August 2010 were selected 50 patients with adnexal mass viewing of the pelvic ultrasound. They were subjected to ultrasound for abdominal and transvaginal routes. The images were captured in static and dynamic modes, electronically forwarded for evaluation of non-presence and two examiners evaluated according to morphological ultrasonographic parameters previously determined. RESULTS: The evaluators did not face in static and dynamic modes obtained almost perfect agreement for all morphological parameters with Kappa values between 0.6 and 0.8. There was no difference between the methods employed, except for the morphological parameter papillary projection in the static mode, in which the agreement was almost perfect (0.8) while in dynamic mode was substantial (0.6). CONCLUSIONS: The sonographic parameters of the features of adnexal masses pelvic sent by tele-ultrasound are capable of being validated for issuing a second opinion. There were no significant differences in the methodology used in the issue of tele-ultrasound images (static or dynamic) to characterize the composition of pelvic adnexal masses.

RESUMO

OBJETIVO: Avaliar os parâmetros ultrassonográficos relacionados às características morfológicas de massas anexiais pélvicas por meio da obtenção de imagens bidimensionais por um observador presencial, encaminhadas eletronicamente (via tele-ecografia) nos modos estático e dinâmico a observadores não presenciais (à distância) para análises comparativas inter e intraobservadores a fim da validação de uma segunda opinião. MÉTODOS: No período de março a agosto de 2010 foram selecionadas 50 pacientes que apresentavam visualização de massa anexial pélvica no exame ecográfico. Elas foram submetidas ao exame ultrassonográfico por vias abdominal e endovaginal. As imagens foram capturadas nos modos estático e dinâmico, encaminhadas eletronicamente para avaliação de dois examinadores não presenciais e avaliadas de acordo com parâmetros morfológicos ultrassonográficos previamente determinados. RESULTADOS: Os avaliadores não presenciais nas modalidades estática e dinâmica obtiveram concordância quase perfeita para todos os parâmetros morfológicos com valores de Kappa entre 0,6 e 0,8. Não houve diferença entre as modalidades empregadas, exceto para o parâmetro morfológico projeção papilar na modalidade estática, em que a concordância foi quase perfeita (0,8) enquanto na modalidade dinâmica foi substancial (0,6). CONCLUSÕES: Os parâmetros ultrassonográficos das características de massas anexiais pélvicas encaminhadas por tele-ecografia são passíveis de serem validadas para emissão de uma segunda opinião. Não houve diferenças significativas quanto à metodologia empregada na emissão das imagens tele-ecográficas (estática ou dinâmica) na caracterização da composição das massas anexiais pélvicas.

RESUMO

TRIAL DESIGN: A randomized controlled trial was performed to evaluate the effect of the combination of compression therapy with active exercising using a facilitating apparatus on arm lymphedema. METHOD: Twenty women with a mean age of 63.3 years were evaluated; all had lymphedema resulting from breast cancer treatment. The inclusion criterion was a difference of 200 mL in size between arms. The apparatus used, called 'pulley system', is a vertical iron wheel fixed on a support at a distance of 10 cm from the patient's body. Participants were submitted to two series of active exercises using this facilitating device, one series using a compression sleeve and the other without. Each series consisted of four 12-minute sessions of exercises separated by 3-minute rest intervals. Volumetry was performed before and after each series of exercises. The paired t-test was utilized for statistical analysis (p-value < 0.05). RESULTS: A significant mean reduction (p-value < 0.007) and non-significant mean increase (p-value < 0.2) in volumes were observed during exercising with and without compression, respectively. CONCLUSION: Controlled active exercising utilizing a facilitating apparatus while wearing a compression sleeve reduces the size of lymphedematous arms.

RESUMO

We evaluated the diagnostic quality of first-trimester ultrasound images transmitted in realtime using low-cost telecommunications. A prospective sample of fetal ultrasound images from 11 weeks to 13 weeks and six days of pregnancy was obtained from pregnant women over 18 years old. The examinations were transmitted in realtime to three independent examiners who carried out a qualitative assessment based on parameters established by the Fetal Medicine Foundation. All fetal structures could be viewed and the quality of images received by the examiners was considered normal. There were significant differences for crown-rump length and nuchal translucency in the transmitted images but the loss in definition was acceptable. Thus the quality of images transmitted via the Internet through the use of low-cost software appeared suitable for screening for chromosomal abnormalities in the first trimester of pregnancy.

RESUMO

OBJECTIVE: Adenosine deaminase acts on adenosine and deoxyadenosine metabolism and modulates the immune response. The adenosine deaminase G22A polymorphism (20q.11.33) influences the level of adenosine deaminase enzyme expression, which seems to play a key role in maintaining pregnancy. The adenosine deaminase 2 phenotype has been associated with a protective effect against recurrent spontaneous abortions in European Caucasian women. The aim of this study was to investigate whether the G22A polymorphism of the adenosine deaminase gene is associated with recurrent spontaneous abortions in Brazilian women. METHODS: A total of 311 women were recruited to form two groups: G1, with a history of recurrent spontaneous abortions (N = 129), and G2, without a history of abortions (N = 182). Genomic DNA was extracted from peripheral blood with a commercial kit and PCR-RFLP analysis was used to identify the G22A genetic polymorphism. Fisher's exact test and odds ratio values were used to compare the proportions of adenosine deaminase genotypes and alleles between women with and without a history of recurrent spontaneous abortion (p<0.05). The differences between mean values for categorical data were calculated using unpaired t tests. The Hardy-Weinberg equilibrium was assessed with a chi-square test. RESULTS: Statistically significant differences were identified for the frequencies of adenosine deaminase genotypes and alleles between the G1 and G2 groups when adjusted for maternal age. CONCLUSIONS: The results suggest that the adenosine deaminase *2 allele is associated with a low risk for recurrent spontaneous abortions, but this association is dependent on older age.
