Seasonal variability in the fertilization rate of women undergoing assisted reproduction treatments

The objective of this study was to evaluate whether seasonality affects human-assisted reproduction treatment outcomes. For this, 1932 patients undergoing intracytoplasmic sperm injection (ICSI) were assigned to a season group according to the day of oocyte retrieval: winter (n = 435), spring (n = 444), summer (n = 469) or autumn (n = 584). Analysis of variance was used to compare the ICSI outcomes. The fertilization rate was increased during the spring (winter: 67.9%, spring: 73.5%, summer: 68.7% and autumn: 69.0%; p < 0.01). In fact, a nearly 50% increase in the fertilization rate during the spring was observed (odds ratio 1.45, confidence interval 1.20-1.75; p < 0.01). The oestradiol concentration per number of oocytes was significantly higher during the spring (winter: 235.8 pg/mL, spring: 282.1 pg/mL, summer: 226.1 pg/mL and autumn: 228.7 pg/mL; p = 0.030). This study demonstrates a seasonal variability in fertilization after ICSI, where fertilization is higher during the spring than at any other time.

Effects of isoflavone on the learning and memory of women in menopause: a double-blind placebo-controlled study

Hormone decline is common to all women during aging and, associated with other factors, leads to cognitive impairment. Its replacement enhances cognitive performance, but not all women present a clinical and family or personal history that justifies its use, mainly women with a history of cancer. The aim of this study was to determine whether a daily oral dose of 80 mg of isoflavone extract for 4 months can produce benefits in women with low hormone levels, contributing to improvement in cognitive aspects. The sample comprised 50- to 65-year-old women whose menstruation had ceased at least 1 year before and who had not undergone hormone replacement. The volunteers were allocated to two groups of 19 individuals each, i.e., isoflavone and placebo. There was a weak correlation between menopause duration and low performance in the capacity to manipulate information (central executive). We observed an increase in the capacity to integrate information in the group treated with isoflavone, but no improvement in the capacity to form new memories. We did not observe differences between groups in terms of signs and symptoms suggestive of depression according to the Geriatric Depression Scale. Our results point to a possible beneficial effect of isoflavone on some abilities of the central executive. These effects could also contribute to minimizing the impact of memory impairment. Further research based on controlled clinical trials is necessary to reach consistent conclusions.

Cervicovaginal aerobic microflora of women with spontaneous abortion or preterm delivery in Araraquara-Brazil

Rotina bacteriológica do conteúdo vaginal e cervical de 22 mulheres com histórico de aborto recente ou ruptura precoce das membranas foi realizada. Chlamydia trachomatis, Streptococcus pyogenes, Streptococcus agalactiae, Candida sp e Gardnerella vaginalis foram isolados em 54,5% (12) das pacientes. Apesar de Ureaplasma urealyticum ter sido frequentemente encontrado (45,5%), somente em 5 das 22 mulheres foi o único microrganismo presente nos materiais analisados. Esses resultados chamam a atenção para a importância de investigação quantitativa bem como qualitativa da microbiota genital em gestantes, tendo em vista ter consequências na gestação.

Feelings and Perceptions of Women in the Pregnancy-Puerperal Cycle Who Survived Severe Maternal Morbidity

Objetivou-se compreender a experiência relativa à morbidade materna grave, a partir de um grupo de mulheres que vivenciou esse problema. Adotaram-se os preceitos metodológicos da pesquisa qualitativa, sendo o Discurso do Sujeito Coletivo o referencial metodológico. Foram entrevistadas 16 mulheres que vivenciaram a morbidade materna grave. Os resultados foram discutidos a partir de quatro temas: descrevendo o desejo e o planejamento para ter um filho, percebendo seu problema de saúde, sua influência na gestação e para o concepto, passando pelo choque inicial no pós-parto e experienciando a situação de risco: desejos, frustrações e superação. Espera-se que este trabalho possa contribuir para qualificar a assistência de enfermagem, especialmente para reconhecer a diversidade e amplitude de necessidades que mulheres apresentam em situações de morbidade grave, durante o ciclo gravídico puerperal.

Tumor necrosis factor-alpha in gestation and puerperium of women with gestational hypertension and pre-eclampsia

Problem High plasma levels of tumor necrosis factor-alpha (TNF-alpha) in pregnant women have been associated with the pathogenesis of pre-eclampsia (PE). This study evaluated TNF-alpha plasma levels and monocyte production in gestational hypertension (GH) and PE during gestation and at puerperium.Method of study This study included 128 women, of whom 20 were non-pregnant (NP) normotensive (NT), and 108 were pregnant: 36 NT, 27 with GH, and 45 with PE. Peripheral blood plasma was used for TNF-alpha and uric acid determination. TNF-alpha was determined in plasma and lipopolysaccharide (LPS)-stimulated and non-stimulated monocyte supernatants by L929 bioassay.Results Tumor necrosis factor-alpha and uric acid plasma levels were higher in PE than in GH pregnancies. In both hypertensive groups, these parameters positively correlated and were significantly more elevated than in NT and NP women. TNF-alpha plasma levels and monocyte production were higher in hypertensive than in NT women during gestation, and significantly decreased at puerperium. Although decreased, TNF-alpha release in LPS-stimulated PE monocytes, was still significantly higher than in the other pregnant groups.Conclusion In vivo monocyte activation in GH and PE pregnant women was characterized by in vitro TNF-alpha production. The fact that higher circulating concentrations of TNF-alpha and uric acid were observed in PE than in GH suggests an association with disease severity.

Correlation between carotenoid concentrations in serum and normal breast adipose tissue of women with benign breast tumor or breast cancer

To evaluate the relationship between carotenoid concentrations in serum and breast tissue, we measured serum carotenoid concentrations and endogenous carotenoid levels in breast adipose tissue of women with benign breast tumor (n = 46) or breast cancer (n = 44). Before extraction, serum was digested with lipase and cholesterol esterase, and breast adipose tissue was saponified. Serum and tissue carotenoids were extracted with ether/hexane and measured by using HPLC with a C30 column. Serum retinoic acid was extracted with chloroform/methanol and measured using HPLC with a C18 column. There were no significant differences in serum carotenoids [lutein, zeaxanthin, cryptoxanthin (both α- and β-), α-carotene, all-trans β-carotene, 13-cis β-carotene and lycopene], retinoids (retinol, all-trans and 13-cis retinoic acids), and α- and -γ- tocopherol concentrations between benign breast tumor patients and breast cancer patients. A substantial amount of 9-cis β- carotene was present in adipose tissue and was the only carotenoid that had a significantly lower level in benign breast tumor patients than in breast cancer patients. Correlations between carotenoid concentrations in serum and in breast adipose tissue were determined by combining the data of the two groups. Concentrations of the major serum carotenoids except cryptoxanthin showed significant correlations with breast adipose tissue carotenoid levels. When the concentrations of serum carotenoids were adjusted for serum triglycerides or LDL, correlations between serum carotenoid concentrations and breast adipose tissue carotenoid levels markedly increased, including that of cryptoxanthin (P <0.001). The strong correlation between serum carotenoid concentrations and endogenous breast adipose tissue carotenoid levels indicate that dietary intake influences adipose tissue carotenoid levels as well as serum concentrations, and that adipose tissue is a dynamic reservoir of fat-soluble nutrients.

Knowledge and practice of women regarding cervical cancer in a primary health care unit

Objectives: evaluating the level of information about the examination of uterine cervical cancer and its association with sociodemographic variables in women of a health care unit in the city of Bauru, São Paulo, Brazil. Methods: we conducted a cross-sectional descriptive study with 370 women aged 25 to 59, through structured interviews in their own homes; we used descriptive statistics and the χ2 test. Results: 40.5% of the women had not undergone the Papanicolaou test at the recommended frequency; 58.2% incorrectly defined the test, and 69.5% did not know about the risk factors for the development of cervical cancer; the knowledge about the test showed statistically significant association with schooling and family income of the studied population. Conclusions: women present deficiencies on the proper practice of the Papanicolaou test, on knowledge about the test, risk factors and prevention methods. Therefore, it is necessary to develop primary health actions for the most vulnerable population.

Increased DNA damage is related to maternal blood glucose levels in the offspring of women with diabetes and mild gestational hyperglycemia

This study aimed at correlating maternal blood glucose levels with DNA damage levels in the offspring of women with diabetes or mild gestational hyperglycemia (MGH). Based on oral glucose tolerance test results and glycemic profiles, 56 pregnant women were allocated into 3 groups: nondiabetes, MGH, and diabetes. The offspring of these women (56 infants) were also evaluated. Maternal peripheral blood and umbilical cord blood samples were collected and processed for biochemical and DNA damage analysis by the comet assay. A positive correlation between maternal blood glucose mean and increased offspring DNA damage levels was observed. Hyperglycemia played a role in offspring DNA damage, but other diabetes-induced complications were also involved. Increased maternal blood glucose levels can lead to increased offspring DNA damage levels. Therefore, the monitoring, control, and treatment of pregnant women with diabetes and MGH are highly important to ensure a risk-free pregnancy and healthy infants.
