Correlación clínica y ecográfica de la maduración y reactividad fetal

Estudio descriptivo de cohorte único para por medio de la clínica (altura de fondo uterino) y del uso de la ecografía (longitud femoral y diámetro biparietal) elaborar curvas de crecimiento fetal y detectar posibles diferencias determinadas por el sexo en el mismo, estudiar la madurez placentaria ecográfica y la respuesta ftal al test de estimulación vibroacústica; en sesenta pacientes embarazadas que acudieron a la consulta externa del Hospital Vicente Corral Moscoso durante el período comprendido entre Marzo de 1992 y julio de 1993, que cumplieron las siguientes características: embarazo de curso clínico normal menor de veinte semanas al momento de la inclusión, ciclos menstruales espontáneos y regulares y no haber usado métodos anticonceptivos tres meses previos al embarazo, luego del parto los criterios fueron: recién nacido normal, de peso adecuado para la edad gestacional y a término. Encontramos que la longitud femoral se inicia con valores de 1.63 centímetros a las doce semanas de gestación, teniendo un comportamiento lineal progresivamente ascendente, con aumento promedio de 0.21 centímetros por semana, para terminar en 7.4 centímetros a la semana 40. Se encuentra que la longitud femoral se inicia con valores de 1.83 centímetros a las doce semanas de gestación, teniendo un comportamiento lineal progresivamente ascendiente, con aumento promedio de 0.21 centímetros por semana, para terminar en 7.4 centímetros a la semana 40. El diámetro biparietal se inicia con valores de 2 centímetros a las doce semanas, tiene un trayecto progresivamente ascendente, iniciando un aplanamiento hacia las 30 semanas, que se acentúa en las últimas semanas del embarazo, terminando en 9.17 a las 40 semanas de gestación. La altura del fondo uterino describe una curva regular con ascenso inicial rápido y luego tendencia al aplanamiento. En los tres parámetros no se evidenciaron diferencias determinadas por el sexo. El grado de maduración placentaria es progresivo. Aparece el grado I a las 27 semanas, el grado II a las 35 semanas y el grado III a las 38 semanas. Se demuestra que la prueba de estimulación vibroacústica es eficiente para la valoración del bienestar fetal, observándose además que a una mayor edad gestacional el incremento de la frecuencia cardíaca fetal es también mayor

A cross sectional study of leptospirosis and fetal death in Yucatan, Mexico

Introduction: Leptospirosis is a zoonotic disease affecting mainly to low income human population. Acute leptospiral infection during pregnancy has been associated with spontaneous abortion and fetal death during the first trimester and the abortion may occur as consequence of systemic failure. Objective: To estimate the frequency of Leptospira interrogans infection in women with spontaneous abortion in the state of Yucatan, Mexico. Methods: A cross sectional study on women with spontaneous abortion was conducted. Serum samples were tested for Leptospirosis by the microaglutination test, to estimate the frequency of the infecting serovar. The indirect ELISA IgM was used to detect recent infection by L. interrogans. DNA was extracted from paraffin-embedded tissue of placenta for PCR detection of L. interrogans. Results: Overall frequency of infection with L. interrogans in the 81 women with abortion was 13.6%. Five of the 12 serovars evaluated were found and included. Two of the 11 women with abortion and positive to microaglutination test were also positive to the ELISA IgM test. None samples were positive for PCR Leptospira diagnosis. Conclusion: two women could be associated with spontaneous abortion due to leptospirosis, because they showed antibodies against L. interrogans in the microaglutination test and ELISA IgM assays. Differences between regions were found with respect to the prevalences of lesptospirosis.

Quando a morte antecede o nascimento: atuação do enfermeiro especialista em saúde materna e obstetrícia na assistência à mulher que vivência uma morte fetal

A perda gestacional é uma experiência dolorosa e complexa para a mãe/casal. O enfermeiro surge como promotor da adaptação á perda. Com esta intervenção, pretendo assegurar boas práticas de enfermagem na assistência às mulheres/casais em situação de perda gestacional. Foi realizado um estudo qualitativo em que se realizaram entrevistas a mulheres que vivenciaram perda gestacional e aos Enfermeiros Especialistas de Saúde Materna e Obstétrica como prestadores de cuidados. Os resultados mostram que os enfermeiros consideram a perda gestacional uma experiência difícil de vivenciar, identificando necessidades de formação. As mulheres referem diferenças na abordagem por parte dos enfermeiros aquando dos cuidados recebidos, falta de apoio e necessidade de encaminhamento após a alta hospitalar. Efetuou-se formação aos enfermeiros com peritos da área e desenvolveram-se procedimentos para uniformizar os cuidados. Foi criado um procedimento para uniformizar a prática e materiais de suporte para o apoio na prestação de cuidados de enfermagem; WHEN THE DEATH ANTECIPATES THE BIRTH: MIDWIVES' ROLE IN ASSISTANCE TO WOMENWHO EXPERIENCE FETAL DEATH. ABSTRACT: Pregnancy loss is a painful and complex experience to the mother/couple. The nurse is the promoting agent to the loss adaptation. With this project, I intend to ensure good nursing practices in assisting women/couples who experience a pregnancy loss. A qualitative study was performed, in which interviews were conducted to women who experienced a pregnancy loss and to nurse-midwives who provided care. Results demonstrated that nurse-midwives find pregnancy loss as a difficult experience, identifying educational needs. Women relate differences in the nurse-midwives’ approach during care, lack of support and the need of follow-up after hospital discharge. Nurse-midwives were subjected to training with experts and procedures were developed in order to standardize care. A practice standardizing procedure and educational materials were created to support nursing practice.

Human congenital cytomegalovirus infection: characteristics and pathogenesis of fetal brain damage

Human cytomegalovirus (HCMV) causes congenital neurological lifelong disabilities. The study analyzed 10 HCMV-infected human fetuses at 21 weeks of gestation to evaluate the characteristics and pathogenesis of brain injury related to congenital human CMV (cCMV) infection. Specifically, tissues from cortical and white matter areas, subventricular zone, thalamus, hypothalamus, hippocampus, basal ganglia and cerebellum were analysed by: i) immunohistochemistry (IHC) to detect HCMV-infected cell distribution, ii) hematoxylin-eosin staining to evaluate histological damage and iii) real-time PCR to quantify tissue viral load (HCMV-DNA). Viral tropism was assessed by double IHC to detect HCMV-antigens and neural/neuronal markers: nestin (expressed in early differentiation stage), doublecortin (DCX, identifying neuronal precursor cells) and neuronal nuclei (NeuN, identifying mature neurons). HCMV-positive cells and viral DNA were found in the brain of 8/10 (80%) fetuses. For these cases, brain damage was classified in mild (n=4, 50%), moderate (n=3, 37.5%) and severe (n=1, 12.5%) based on presence of i) diffuse astrocytosis, microglial activation and vascular changes; ii) occasional (in mild) or multiple (in moderate/severe) microglial nodules and iii) necrosis (in severe). The highest median HCMV-DNA level was found in the hippocampus (212 copies/5ng of humanDNA [hDNA], range: 10-7,505) as well as the highest mean HCMV-infected cell value (2.9 cells, range: 0-23), followed by that detected in subventricular zone (1.8 cells, range: 0-19). This suggests a preferential HCMV tropism for immature neuronal cells, residing in these regions, confirmed by the detection of DCX and nestin in 94% and 63.3% of HCMV-positive cells, respectively. NeuN was not found among HCMV-positive cells and was nearly absent in the brain with severe damage, suggesting HCMV does not infect mature neurons and immature HCMV-infected neuronal cells do not differentiate into neurons. HCMV preferential tropism in immature neural/neuronal cells delays/inhibits their differentiation interfering with brain development processes that lead to structural and functional brain defects.

Indole-3-carbinol Attenuates The Deleterious Gestational Effects Of Bisphenol A Exposure On The Prostate Gland Of Male F1 Rats.

Bisphenol A (BPA) is a chemical that has been investigated for it potential to cause prostate diseases. In this study, pregnant Sprague-Dawley rats were treated with 25 or 250 μg/kg BPA from gestational day (GD) 10 to GD21 with or without concurrent indole-3-carbinol (I3C) feeding. I3C is a phytochemical, and it affords chemoprotection against many types of neoplasia. Male F1 rats from different litters were euthanized on post-natal day (PND) 21 and PND180. BPA-treated groups showed a significant increase in histopathological lesions, but I3C feeding reversed many of these changes, mainly at PND180. Maternal I3C feeding increased prostate epithelial apoptosis in the BPA-treated groups and across age groups. Furthermore, I3C induced partial normalization of the prostate histoarchitecture. The results pointed to a protective effect of maternal I3C feeding during pregnancy in the BPA-exposed male offspring, thereby indicating reduction in the harmful effects of gestational BPA imprinting on the prostate.

Long-term Results Of Anderson-hynes Pyeloplasty In Children: How Long Follow-up Is Necessary?

Purpose After a successful pyeloplasty at 3 to 6 months, the question remains whether children need a long follow-up. Methods The medical charts of patients with long-term follow-up (> 5 years), who underwent dismembered pyeloplasty for uretero-pelvic junction obstruction (UPJO) from May 1998 to May 2007, excluding those with bilateral UPJO, solitary kidney, associated vesicoureteral reflux or other abnormalities, and inconclusive renogram due to poor renal function, were retrospectively reviewed. Ultrasonography, differential renal function (DRF, DMSA), and renal drainage on diuretic renography (diethylene-triamine-pentaacetate technetium-99 or DTPA-Tc99) were performed at 3 and 6 months every year. Results Complete data were available for 28 consecutive patients (28 renal unities) with 2 months to 12 years (mean age, 2.4 years) at surgery, of whom 21 (75%) were boys, 17 diagnosed prenatally (61%) and 18 unities (64.3%) were left, with median follow-up of 10.7 years. Images were graded according to the Society for Fetal Urology grading system: Grade III in 11 (49%) and grade IV in 17 (61%). All cases presented > 10% DRF (DMSA) and obstructed DTPA-Tc99. The T1/2 (the half-time of drainage) less than 20 minutes at 3 months was found in 21 cases (75%) and less than 25 minutes in 7 cases (25%). Renal function and patency were maintained during follow-up for all units with 8% maximum fluctuation of DRF. One index case (3.6%) of renal function deterioration presented DRF fluctuation > 8% at 3 months (from 23 to 32%) and progressive hydronephrosis and indeterminate DTPA at 6 months. Conclusions Satisfactory diuretic renogram at 3 to 6 months after pyeloplasty with maintained renal function and stable hydronephrosis suggests no need for further follow-up and indicates no functional loss with time. More than 8% DRF fluctuation might be a significant cutoff for further intervention aiming nephron preservation.

Association Of Lipophilic Opioids And Hyperbaric Bupivacaine In Spinal Anesthesia For Elective Cesarean Section. Randomized Controlled Study.

To evaluate the efficacy and side-effects of fentanyl and sufentanil combined with hyperbaric spinal bupivacaine in elective cesarean section. A prospective, randomized, double-blind study with 64 term parturients, distributed into 2 groups according to the opioid combined with hyperbaric bupivacaine 0.5% (10mg): GF - fentanyl (25 µg) and GS - sufentanil (5.0 µg). The latency and maximum sensory block level; degree and duration of motor block; duration and quality of analgesia; maternal-fetal repercussions were evaluated. This was an intention-to-treat analysis with a 5% significance level. The latency period, maximum sensory block level, motor block degree and perioperative analgesia were similar in both groups. Motor block and analgesia had a longer duration in the sufentanil group. Maternal adverse effects and neonatal repercussions were similar. The incidence of hypotension was higher in the fentanyl group. In both groups, there was a predominance of patients who were awake and either calm or sleepy. The addition of fentanyl and sufentanil to hyperbaric subarachnoid bupivacaine was shown to be effective for the performance of cesarean section, and safe for the mother and fetus. Analgesia was more prolonged with sufentanil.

Pregnancy In Women Undergoing Hemodialysis: Case Series In A Southeast Brazilian Reference Center.

To describe maternal and neonatal outcomes in pregnant women undergoing hemodialysis in a referral center in Brazilian Southeast side. Retrospective and descriptive study, with chart review of all pregnancies undergoing hemodialysis that were followed-up at an outpatient clinic of high- risk prenatal care in Southeast Brazil. Among the 16 women identified, 2 were excluded due to follow-up loss. In 14 women described, hypertension was the most frequent cause of chronic renal failure (half of cases). The majority (71.4%) had performed hemodialysis treatment for more than one year and all of them underwent 5 to 6 hemodialysis sessions per week. Eleven participants had chronic hypertension, 1 of which was also diabetic, and 6 of them were smokers. Regarding pregnancy complications, 1 of the hypertensive women developed malignant hypertension (with fetal growth restriction and preterm delivery at 29 weeks), 2 had acute pulmonary edema and 2 had abruption placenta. The mode of delivery was cesarean section in 9 women (64.3%). All neonates had Apgar score at five minutes above 7. To improve perinatal and maternal outcomes of women undergoing hemodialysis, it is important to ensure multidisciplinary approach in referral center, strict control of serum urea, hemoglobin and maternal blood pressure, as well as close monitoring of fetal well-being and maternal morbidities. Another important strategy is suitable guidance for contraception in these women.

Association Between Parity, Pre-pregnancy Body Mass Index And Gestational Weight Gain.

To analyze the relationship between parity, pre-pregnancy body mass index (BMI), and gestational weight gain (GWG). This observational controlled study was conducted from November 2013 to April 2014, with postpartum women who started antenatal care up to 14 weeks and had full-term births. Data were collected from medical records and antenatal cards. Descriptive and bivariate analyses were performed. The significance level was 5%. Data were collected from 130 primiparous and 160 multiparous women. At the beginning of prenatal care, 54.62% of the primiparous were eutrophic, while the majority of multiparous were overweight or obese (62.51%). Multiparas are two times more likely to be obese at the beginning of their pregnancies, when compared to primiparas. The average pre-pregnancy weight and final pregnancy weight was significantly higher in multiparous, however, the mean GWG was higher among primiparous. We found an inverse correlation between parity and the total GWG, but initial BMI was significantly higher in multiparas. Nevertheless, monitoring of the GWG through actions that promote a healthier lifestyle is needed, regardless of parity and nutritional status, in order to prevent excessive GWG and postpartum weight retention and consequently inadequate pre-pregnancy nutritional status in future pregnancies.

A Leucine-rich Diet Modulates The Tumor-induced Down-regulation Of The Mapk/erk And Pi3k/akt/mtor Signaling Pathways And Maintains The Expression Of The Ubiquitin-proteasome Pathway In The Placental Tissue Of Nmri Mice.

Placental tissue injury is concomitant with tumor development. We investigated tumor-driven placental damage by tracing certain steps of the protein synthesis and degradation pathways under leucine-rich diet supplementation in MAC16 tumor-bearing mice. Cell signaling and ubiquitin-proteasome pathways were assessed in the placental tissues of pregnant mice, which were distributed into three groups on a control diet (pregnant control, tumor-bearing pregnant, and pregnant injected with MAC-ascitic fluid) and three other groups on a leucine-rich diet (pregnant, tumor-bearing pregnant, and pregnant injected with MAC-ascitic fluid). MAC tumor growth down-regulated the cell-signaling pathways of the placental tissue and decreased the levels of IRS-1, Akt/PKB, Erk/MAPK, mTOR, p70S6K, STAT3, and STAT6 phosphorylated proteins, as assessed by the multiplex Millipore Luminex assay. Leucine supplementation maintained the levels of these proteins within the established cell-signaling pathways. In the tumor-bearing group (MAC) only, the placental tissue showed increased PC5 mRNA expression, as assessed by quantitative RT-PCR, decreased 19S and 20S protein expression, as assessed by Western blot analysis, and decreased placental tyrosine levels, likely reflecting up-regulation of the ubiquitin-proteasome pathway. Similar effects were found in the pregnant injected with MAC-ascitic fluid group, confirming that the effects of the tumor were mimicked by MAC-ascitic fluid injection. Although tumor progression occurred, the degradation pathway-related protein levels were modulated under leucine-supplementation conditions. In conclusion, tumor evolution reduced the protein expression of the cell-signaling pathway associated with elevated protein degradation, thereby jeopardizing placental activity. Under the leucine-rich diet, the impact of cancer on placental function could be minimized by improving the cell-signaling activity and reducing the proteolytic process.
