Gravidez na adolescência: percepções das mães de gestantes jovens

OBJETIVO: Conhecer as experiências e percepções de mães cujas filhas engravidaram durante a adolescência. MÉTODOS: Pesquisa de abordagem qualitativa, realizada em hospital de ensino na cidade de São Paulo, com coleta de dados realizada por meio de roteiro de entrevista semiestruturada e com participação de dez mães de adolescentes. RESULTADOS: Antes da gravidez, as mães orientaram as filhas a respeito da sexualidade, o que originou sentimentos de surpresa quando souberam da gravidez. Apesar disso, as mães fizeram-se presentes em todo o processo gravídicopuerperal. Não foram identificadas mudanças significativas no relacionamento familiar em função da gravidez precoce. CONCLUSÃO: A figura materna surge como representativa, tanto durante como após a gestação da adolescente, fato que propicia o suporte, a fim de que a adolescente tenha gestação mais segura e para que possa retomar seus projetos de vida.

Being the mother of a pregnant adolescent: experiences and expectations

OBJECTIVE: To understand the typical actions of the mother during the pregnancy of her teenage daughter. METHODS: Qualitative study, based on the theoretical-methodological framework of social phenomenology of Alfred Schütz. The data were collected in 2009, and the subjects were nine mothers of adolescent primigravidae. RESULTS: The mother of the pregnant adolescent is typified as one that reacts with surprise and disappointment to being notified of the pregnancy and who, subsequently, conforms to the new reality. In reflecting on her own experience of an adolescent mother, she has expectations to support her daughter during the pregnancy and to offer support, so that the course of her life is not impaired as a result of pregnancy. CONCLUSION: Considering the experience and expectations of the mother of the pregnant adolescent, this study could give subsidies to the planning and execution of the care for this binomial, decreasing the distance between the demands made by it and the practice of health professionals.

A jovem mãe e o mercado de trabalho

INTRODUÇÃO: O Centro de Orientação ao Adolescente de Campinas mantém um programa para capacitar adolescentes de 15 a 18 anos, desfavorecidos economicamente, estudantes, para a entrada no mercado de trabalho. OBJETIVO: Compreender projetos de vida de adolescentes, que se tornaram mães, enquanto participavam do programa, no período de 2003 a 2008, buscando desvelar o lugar da vida profissional na trajetória de vida, antes e depois da maternidade. MÉTODO: Oito jovens mães foram entrevistadas, sendo aplicada metodologia qualitativa para a análise das entrevistas. RESULTADOS: As trajetórias de estudo e trabalho foram descontinuadas, ou sofreram adaptações, com a maternidade. Quatro jovens finalizaram o segundo grau e nenhuma havia ingressado na faculdade. Três não voltaram a trabalhar e as demais tiveram experiências diversificadas de trabalho. As dificuldades relatadas para a inserção no mercado de trabalho foram: insuficiência de instrumentos de apoio no cuidado das crianças, baixo ganho salarial, falta de experiência de trabalho, filhos pequenos e pouca formação educacional. CONSIDERAÇÕES FINAIS: A maternidade na adolescência não indicou a exclusão dos projetos de formação educacional ou de trabalho, mas adaptações e necessidade de uma rede de apoio familiar e social. Constatou-se a necessidade de políticas públicas para a inserção do jovem no mercado de trabalho e para serviços de apoio, como creches. Demonstra-se a necessidade de uma mudança nas relações de gênero, com maior igualdade de direitos, como pré-condição à inserção da mulher no mercado de trabalho, em especial, daquelas que são mães.

Clinical and biochemical consequences of p450 oxidoreductase deficiency

Patients with P450 oxidoreductase (POR) deficiency typically present with adrenal insufficiency, genital anomalies and bony malformations resembling the Antley-Bixler craniosynostosis syndrome. Since our first report in 2004, more than 40 POR mutations have been identified in over 65 patients. POR is the obligate electron donor to all microsomal P450 enzymes, including the steroidogenic enzymes CYP17A1, CYP21A2 and CYP19A1. POR deficiency may cause disordered sexual development manifested as genital undervirilization in 46, XY newborns as well as overvirilization in those who are 46, XX. This may be explained by impaired aromatization of fetal androgens that may cause maternal virilization and low urinary estriol levels during pregnancy. In addition, the alternate 'backdoor' pathway of androgen biosynthesis, which leads to dihydrotestosterone production bypassing androstenedione and testosterone, may also play a role. Functional assays studying the effects of POR mutations on steroidogenesis showed that several POR variants impaired CYP17A1, CYP21A2 and CYP19A1 activities to different degrees, indicating that each POR variant must be studied separately for each potential target P450 enzyme. POR variants may also affect skeletal development and drug metabolism. As most drugs are metabolized by hepatic microsomal P450 enzymes, studies of the impact of POR mutations on drug-metabolizing P450s are particularly important.

Proteome analysis of human plasma and amniotic fluid by Off-Gel isoelectric focusing followed by nano-LC-MS/MS

This paper presents a comparative proteomic analysis of human maternal plasma and amniotic fluid (AF) samples from the same patient at term of pregnancy in order to find specific AF proteins as markers of premature rupture of membranes, a complication frequently observed during pregnancy. Maternal plasma and the corresponding AF were immunodepleted in order to remove the six most abundant proteins before the systematic analysis of their protein composition. The protein samples were then fractionated by IEF Off-Gel electrophoresis (OGE), digested and analyzed with nano-LC-MS/MS separation, revealing a total of 73 and 69 proteins identified in maternal plasma and AF samples, respectively. The proteins identified in AF have been compared to those identified in the mother plasma as well as to the reference human plasma protein list reported by Anderson et al. (Mol. Cell. Proteomics 2004, 3, 311-326). This comparison showed that 26 proteins were exclusively present in AF and not in plasma among which 10 have already been described to be placenta or pregnancy specific. As a further validation of the method, plasma proteins fractionated by OGE and analysed by nano-LC-MS/MS have been compared to the Swiss 2-D PAGE reference map by reconstructing a map that matches 2-D gel and OGE experimental data. This representation shows that 36 of 49 reference proteins could be identified in both data sets, and that isoform shifts in pI are well conserved in the OGE data sets.

First Trimester Screening and its Impact on Uptake of Diagnostic Testing

Introduction: First Trimester Screening (FTS) combines maternal age with fetal nuchal translucency (NT) and maternal analytes to identify pregnancies at an increased risk for Down syndrome and trisomy 18. Though the accuracy of this screening is high, it cannot replace the conclusive accuracy of prenatal diagnostic testing (PDT). Since FTS has been available, a decrease in the number of women who pursue PDT has been observed. This study sought to determine if there has been a significant change in the amount of PDT performed in our clinics, if the type of FTS result affects the patient’s decision regarding PDT, and what the patient’s intentions are regarding PDT. Material and Methods: A database review was performed for the two years prior and the two years after the January 2007 American College of Obstetricians and Gynecologists (ACOG) guidelines regarding FTS were issued. We compared the number of women who were AMA and the number of women who were AMA and had PDT between those time periods. We also determined the number of positive and negative FTS results, and determined how many of those patients had PDT. Finally, we surveyed our patients and referring physicians to determine: what the patient understands about FTS, what the patient’s intentions are regarding FTS, and how physicians present the option of FTS to their patients. Results: We determined that there was a 19.6% decrease in the amount of PDT performed when we compared the two time periods at our three specified clinics. Many of our patients were against having PDT prior to their genetic counseling session, but after they received genetic counseling, 76% of our population became open to the possibility of having PDT. Conclusion: Similar to previous studies, we determined that there has been a significant decrease in the number of PDT procedures performed at our clinics, which coincides with the release of the January 2007 ACOG statement regarding FTS. While our patients regarded FTS as a way to gain early information about their pregnancy in a non-invasive manner, they also stated they would use their results as a way to aid in their decision regarding PDT.

The relationship between rheumatoid arthritis and reproductive function

There is growing support for the theory that an interaction between the immune and reproductive/endocrine systems underlies the pathogenesis of autoimmune rheumatic diseases. Most of the recent evidence derives from studies of sex hormones and pregnancy in women with systemic lupus. Other than an ameliorative effect of pregnancy, little is known about reproductive factors in relation to rheumatoid arthritis. To elucidate the relationship, a population-based retrospective study was undertaken. Included were 378 female residents of Olmsted County, Minnesota diagnosed with rheumatoid arthritis between 1950 and 1982 (cases) and 325 arthritis-free, married female controls matched to the 324 married cases on birth-year, age at first marriage, and duration of Olmsted County residency. Information of reproductive factors was extracted from the medical records system maintained by the Mayo Clinic.^ Cases had lower fertility rates compared with the female population of Minnesota (rate ratio = 0.86, 95% confidence interval (CI)= 0.80-0.92). Fertility was significantly reduced even prior to the onset of rheumatoid factor positive arthritis. Restricting the comparison to married Olmsted County residents did not alter the results. Further adjustments for time not at risk of conception using survival analysis and proportional hazards modeling only intensified the fertility reduction in the married cases compared with controls. Nulligravidity was more common among cases than controls (odds ratio = 3.16, CI = 1.61-6.20). Independent of fertility, pregnancy had a protective effect against rheumatoid arthritis (odds ratio = 0.31, CI = 0.11-0.89), which was dramatically reversed in the 12 months postpartum (odds ratio = 4.67, CI = 1.50-14.47). Cases were younger at menopause than controls (p $<$ 0.01).^ Small but statistically insignificant associations were observed between rheumatoid arthritis and the following factors: increased frequency of complaints to a physician of infertility; increased frequency of spontaneous abortion, premature birth, and congenital malformations following arthritis onset; and increased prevalence of menopause at arthritis onset. Cases did not differ from controls on age at menarche, duration of pregnancy, or birth weight.^ The findings provide further support for the involvement of the reproductive/endocrine systems in the pathogenesis of autoimmune rheumatic disease. The search for biological mechanisms should be intensified. ^

Project Alpha: A culturally appropriate approach to adolescent male sex education

In the United States today, adolescents face unacceptably high rates of mortality and morbidity due to the contraction of HIV/AIDS, sexually transmitted diseases and teenage pregnancy. In view of these rates, there is a need for applied preventive interventions to delay adolescent sexual behavior until adulthood. Project Alpha was a school-adopted, quasi-experimental program for adolescent male students attending Sharpstown High School in Houston, Texas. This intervention used student newsletters to provide specific role-model stories on community and student role models who have changed attitudes or improved efficacy to abstain from sexual behavior until adulthood. It was hypothesized that teenagers exposed to the intervention would show improvements in knowledge, beliefs, avoidance skills, perceived norms, intentions and self-efficacy to delay sexual behavior compared to no-treatment reference teenagers in the same school.^ In total, the Project Alpha program had a significant effect on student knowledge, beliefs (towards abstinence and having sex with multiple partners), perceived risk (HIV/STD testing), self-efficacy (could avoid sex with attractive girl who wants to have sex), perceived social norms (friends believing in sexual abstinence) and sexual intentions. However, no significant intervention effects were found in student's beliefs (that it was OK to have sex with girlfriend), perceived risk of HIV/STD, self-efficacy (to avoid sex with girlfriend) and social norms (friends believe it is OK to have sex with a girlfriend and multiple partners in the same month). ^

Is preeclampsia associated with restless legs syndrome?

OBJECTIVE Restless legs syndrome (RLS) is a common neurologic disorder. Secondary RLS includes pregnancy and iron deficiency. Prevalence of RLS in pregnancy ranges from 11% to 27%. We aimed to assess the frequency and characteristics of RLS in pregnancy in a Peruvian population and to evaluate the possible pregnancy or delivery complications due to RLS. METHODS We assessed 218 consecutive expectant mothers at the inpatient clinic of the Hospital San Bartolome in Lima, Peru. Assessment was performed by using the standard diagnostic criteria for RLS and by using a clinical and diagnostic interview. Questionnaires for RLS severity, idiopathic RLS (IRLS), and excessive daytime sleepiness (EDS) according to the Epworth sleepiness scale (ESS) were used. Blood examination was performed for hemoglobin and hematocrit. For comparison, RLS patients were matched for age and body mass index (BMI) with pregnant women without RLS. RESULTS Out of 218 patients, 40 (18.4%) fulfilled diagnostic criteria for RLS. In RLS patients, prophylactic iron supplementation therapy during pregnancy was less frequently taken (P=.02). Pregnant women with RLS had a higher ESS score than pregnant controls (10.6 +/- 3.1 vs 7.6. +/- 3.6; P<.001). Preeclampsia was more frequent in RLS (7/40 vs 1/39; P=.03). CONCLUSIONS In our study, RLS was frequent in pregnant Peruvian women, especially in those without prophylactic iron supplementation. RLS patients described more EDS. Preeclampsia was more common in RLS. Our study is the first study to indicate a possible association between RLS and preeclampsia.

Social cognitive theory and factors associated with Mexican-American parents' beliefs, attitudes and practices regarding communication with their adolescent children about sex

Latinos have the highest teen birth rate nationally. Cameron County, Texas is primarily Latino (Mexican-American). This mixed-method study (n=43) examines Mexican-American parents of adolescents' beliefs, attitudes and practices regarding communication with their adolescent children about sex. Social Cognitive Theory (SCT) constructs self-efficacy, behavioral determinism, environment, outcome expectations and reciprocal determinism can be influences on frequency and quality of parent-adolescent sex communication.^ This study describes Mexican-American parents' of adolescents recollections of their own experiences associated with learning about sexuality. It also examines the attitudes and practices regarding communication about sex and the self-efficacy and behavioral capability of participants to teach their adolescent children about sex and sexually transmitted infections. ^ Negative childhood experiences (shame, lies and trauma) of the parents in this study played a key role in terms of their desire to communicate more comprehensively about sexuality with their own children than did their parents. While participants' reported low self-efficacy and behavioral capability to communicate with their adolescent children about sex, they reported relatively high frequency and quality of communication, with 75% of participants receiving a high quality score and over 44% reporting frequent communication with their adolescent children about sex. A Chi square analysis and Fisher's Exact Score revealed no association between acculturation status, gender or having a child who has mothered/fathered a baby and the frequency or quality of communication about sex with adolescent children. Study participants also gave specific recommendations for method, content and setting of sex education for their children and themselves. Promotora delivery of information and education in a comfortable, culturally appropriate neighborhood setting, as well as parent –child learning sessions were identified as possible approaches to address improve self-efficacy and behavioral capability of parents communicating with their adolescent children about sex.^ The results of this analysis provide public health practitioners and interested community entities data to identify and develop interventions that use a theoretical, evidence-based framework for culturally appropriate interventions to encourage and equip Mexican-American parents to effectively communicate with their adolescent children about sexuality, and ultimately to address the high rates of teen pregnancy in this U.S.-Mexico border community. ^

Attitudes of health-care workers toward pregnant, HIV -positive women

The management of HIV infection with antiretroviral drugs has succeeded in increasing survival rates, but the subject of pregnancy in HIV-positive women continues to garner debate. Discrimination and stigma have been identified as barriers to health care, suggesting that women with HIV may be disinclined to seek prenatal care if health-care workers exhibit negative attitudes toward the women's pregnancies. To optimize prenatal and medical care for women with HIV infection, it is important to understand the general social conditions and cultural context in which these women have children. Goffman's treatise on stigma, Foucault's discussion of the knowledge/power matrix, and Bandura's Social Cognitive Theory offer theoretical perspectives by which we can evaluate the gender, race, and class issues that are inherent in pregnancy decision-making for women with HIV infection. It is also necessary to evaluate prevailing attitudes on childbearing toward HIV-positive women and to review the historical background of prejudice in which HIV-positive women make decisions regarding childbearing. ^ This qualitative study used a survey instrument and one-on-one interviews with HIV-infected women to elicit their perceptions of how they were treated by care providers when they became pregnant. It also included interviews with health-care workers to determine what their feelings are about pregnancy within the context of HIV infection. Results of the ethnographic inquiry reveal that most of the women had negative experiences at some point during a pregnancy, but that the situation improved when they sought care from a provider who was familiar with HIV infection. The health-care providers interviewed were firm in their belief that HIV-positive women deserved optimal care and treated the women with respect, but these are individuals who are also experts in providing care to HIV-positive patients. The question remains as to what kind of care HIV-positive women are receiving generally and what types of attitudes they are being subjected to if they see less experienced providers. Further research is also needed to determine whether HIV-positive women from a broader ethnic representation and higher socioeconomic status experience similar negative attitudes. ^

Aborto inducido y embarazo no planeado en Guatemala

Aunque la legislación guatemalteca permite el aborto inducido solamente para salvar la vida de la mujer, con frecuencia muchas mujeres obtienen abortos, en condiciones de riesgo, y en respuesta a un embarazo no planeado. Estudios recientes indican que el aborto inseguro es un factor clave que contribuye a la morbilidad y mortalidad materna en el país; sin embargo, no existen datos a nivel nacional sobre la incidencia del aborto.

Minors’ Rights as Parents

Many states require parental involvement in a minor’s decision to terminate a pregnancy. In sharp contrast, states overwhelmingly consider minors who are parents to be capable of making critical decisions affecting the health and welfare of their children without their own parents’ knowledge or consent. Nearly every state permits minor parents to place a child for adoption, although some require an adult to be involved in the process in some capacity. Moreover, most states authorize minor parents to make health decisions for their children, and some allow minor parents to authorize surgery.

Actitudes de la mujer ante el embarazo

The authors investigate the correlations between the acceptance and refusal attitudes in regard to pregnancy and absence o presence of distocic factors during childbirth. In order to evaluate it, they apply a projective test visual stimulation which tries to show the woman's atiudes in regard o pregnancy in several vital situations, trying to test its correlations with the pregnancy and childbirth caracteristics.

Historias de hormonas en Argentina : La obesidad de los niños y el diagnóstico precoz del embarazo en las décadas de 1930 y 1940

Este artículo aborda, desde una perspectiva de género, la producción de saberes sobre hormonas en Argentina, en las décadas de 1930 y 1940. Entendemos que un análisis histórico de las ideas científicas y las prácticas clínicas permite indagar en cómo éstas se entraman tanto con el escenario social del que forman parte como con los contextos institucionales donde se elaboran. Focalizaremos en las miradas de los endocrinólogos del Hospital de Niños de Buenos Aires sobre la obesidad en la infancia y el síndrome adiposo genital, y los debates en la Sociedad de Obstetricia y Ginecología de Buenos Aires sobre las técnicas de detección precoz del embarazo y la hormona gonadotropina coriónica
