Monitorización clínica de la dilatación cervical en labor de parto normal en posición vertical materna. Hospital Vicente Corral Moscoso Cuenca 2000

El presente estudio es clínica comparativo, tipo prospectivo para controlar la labor de parto, mediante monitorización clínica, y realizar curvas de alerta de la dilatación cervical, las curvas fueron graficadas en el formulario del partograma, en gestantes que acudieron al servicio de Ginecología-obstetricia del Hospital Vicente Corral Moscoso de Cuenca, durante el año 1999-2000. Se estudiaron 200 gestantes, las cuales se encontraron entre los 15 y 35 años de edad, todas cumplieron los criterios de inclusión. Se divideron en 2 grupos Así: 100 gestantes multíparas y 100 primigestas, con membranas íntegras. Luego de obtenidas las curvas de alerta se evidenció que no hay diferencia entre las curvas diseñadas, tanto para gestantes multíparas como para primigestas, por esta razón se obtuvo una sola curva en promedio. Las curvas se graficaron desde los tres centímetros de dilatación cervical, se comparó con la curva del CLAP, desde los 4.5 cm., nuestra curva de alerta tiene el mismo tiempo de duración de la dilatación cervical que la curva de alerta del CLAP, pero nuestra curva es más vertical desde los 5 a 10 cm. de dilatación, con una diferencia de aproximadamente 30 minutos. Producto de la presente investigación se elaboró plantillas con la curva de alerta, dos formularios, y sus respectivos instructivos

Valoración ecográfica durante la labor de parto

Se realizó un estudio clínico descriptivo en 80 pacientes en labor de parto, en el Hospital Vicente Corral Moscoso de la ciudad de Cuenca en 1995, con el objeto de evaluar ecográficamente, durante la labor de parto, la estática, antropometría, el grado de bienestar fetal y determinar el perfil neuroconductal. Se establecieron 2 grupos; un grupo control conformado por 40 pacientes en labor de parto en las que se realizó el control clínico y un grupo de pacintes [grupo de estudio] en las que además de la valoración se realizó el control ecográfico, considerando principalmente como parámetros de control agudos de movimientos respiratorios, movimientos oculares, movimientos corporales y bucales, el tono fetal y la estimulación vibroacústica tipo 1 [reflejo de sobresalto]. Se encontró que el perfil neuroconductual planteado en el trabajo tiene una sensibilidad del 100 por ciento, con una especificidad del 82.6 por ciento, un valor predictivo de la prueba negativa del 100 por ciento. La exactitud es de 90 por ciento y el índice de Kappa de 0.75 por ciento. La prueba de Fisher, al comparar cada uno de los parámetros con la valoración del Apgar es significativa con una probabilidad de p menos 0.01. La escala de puntuación utilizada incluyó; 10, feto sano; 8, sospecha de hipoxia fetal; 6, hipoxia fetal leve; 4 hipoxia fetal moderada; y 0-2, hipoxia fetal grave. Se observó correlación entre puntaje del perfil neuroconductual y el exámen clínico del recién nacido. Durante la labor de parto el diámetro biparietal para la estimación del peso fetal no tiene utilidad clínica. Se acompaña una revisión bibliográfica exhaustiva, se exponen las conclusiones y se realizan las recomendaciones pertinentes

Alteración del PH vaginal e infección genital en pacientes con amenaza de parto pretérmino, en el Hospital Vicente Corral Moscoso, Cuenca 2003

Teniéndo un OR> 1 que es un factor negativo para el curso del embarazo. Existe a su vez un RR mayor de tener parto prematuro ante la presencia de infección y pH alterado. Los gérmenes aislados más frcuentes en casos y controles fueron Ureoplasma. La sensibilidad del pH para detectar infecciones fue de 86.3. La especificidad 91.7, el valor predictivo positivo de 98.7. Los pacientes con un pH vaginal anormal tienen mayor riesgo de poseer una infección genital y presentar amenaza de parto pretérmino

Análise e proposição de estratégias de estimação e controle de velocidade para motores de indução trifásicos

This study presents a proposal of speed servomechanisms without the use of mechanical sensors (sensorless) using induction motors. A comparison is performed and propose techniques for pet rotor speed, analyzing performance in different conditions of speed and load. For the determination of control technique, initially, is performed an analysis of the technical literature of the main control and speed estimation used, with their characteristics and limitations. The proposed technique for servo sensorless speed induction motor uses indirect field-oriented control (IFOC), composed of four controllers of the proportional-integral type (PI): rotor flux controller, speed controller and current controllers in the direct and quadrature shaft. As the main focus of the work is in the speed control loop was implemented in Matlab the recursive least squares algorithm (RLS) for identification of mechanical parameters, such as moment of inertia and friction coefficient. Thus, the speed of outer loop controller gains can be self adjusted to compensate for any changes in the mechanical parameters. For speed estimation techniques are analyzed: MRAS by rotóricos fluxes MRAS by counter EMF, MRAS by instantaneous reactive power, slip, locked loop phase (PLL) and sliding mode. A proposition of estimation in sliding mode based on speed, which is performed a change in rotor flux observer structure is displayed. To evaluate the techniques are performed theoretical analyzes in Matlab simulation environment and experimental platform in electrical machinery drives. The DSP TMS320F28069 was used for experimental implementation of speed estimation techniques and check the performance of the same in a wide speed range, including load insertion. From this analysis is carried out to implement closed-loop control of sensorless speed IFOC structure. The results demonstrated the real possibility of replacing mechanical sensors for estimation techniques proposed and analyzed. Among these, the estimator based on PLL demonstrated the best performance in various conditions, while the technique based on sliding mode has good capacity estimation in steady state and robustness to parametric variations.

A prática baseada na evidência : a amamentação como fator preventivo da depressão pós-parto

Enquadramento: É expectável que o pós-parto seja um período de alegria. Todavia, nem sempre é assim, já que pode ser um período marcado por momentos de tristeza, cansaço e desânimo. Reconhecendo as vantagens da amamentação para a saúde e bem-estar do recémnascido e da mãe, acreditamos que esta possa ser preventiva da depressão pós-parto. Objetivos: Obter a melhor evidência científica para compreender se a amamentação tem efeito preventivo na depressão pós-parto. Método: Foi efetuada uma revisão integrativa da literatura sobre a relação entre a amamentação e a depressão pós-parto através das bases de dados: EBSCO host, LILACS, PubMed, SciELO, Repositórios institucionais e Google Académico. Selecionaram-se quinze artigos que obedeceram aos critérios de inclusão deste estudo. Resultados: A maioria dos estudos identifica a amamentação como sendo preventiva da depressão pós-parto, destacando a importância da amamentação para a saúde mental da puérpera e consequentemente para a diminuição das hipóteses de desenvolver depressão pósparto. Cinco artigos identificam-na também como sendo um fator de risco e um estudo não encontrou uma associação clara entre a amamentação e a depressão pós-parto. Conclusões: São descritos vários benefícios da amamentação, os quais terão um efeito preventivo contra a depressão pós-parto. Uma mulher informada e apoiada acerca da amamentação será capaz de se sentir confiante no seu novo papel. É essencial um investimento constante por parte da equipa de saúde, iniciado durante o processo do planeamento do casal para a gravidez, e mantendo-se ao longo da gravidez, parto e pós-parto. Palavras-chave: “Amamentação”, “depressão pós-parto”, “prevenção”.

Avaliação de megadoses de retinol palmitato no pós-parto imediato sobre o retinol do leite de puérperas atendidas no Hospital José Pedro Bezerra, Natal-RN

Vitamin A deficiency (VAD) is a serious public health problem in developing countries, and as a therapeutic and prophylactic measure retinil palmitate is being supplemented. Nevertheless its efficacy has been questioned. The objective of the study was to evaluate the supplementation of two retinil palmitate megadosis on the serum retinol levels of post partum healthy mothers from Dr. José Pedro Bezerra (Hospital Santa Catarina) hospital, Natal - RN. The enrolled women (n=199) were randomly distributed into three studied groups and supplemented with retinil palmitate immediately after delivery with a single 200,000 IU dose (group S1), two 200,000 IU dose (group S2) with 24h difference between the doses, or no supplementation (group C). Among women selected, 143 remained until the end of the study. The influence of vitamin A dietary intake was evaluated during pregnancy and after 30 days of delivery. The average intake of the population was reasonable, but a high prevalence of inadequate intake was found. Retinol in colostrums and mature milk was determined by high performance liquid chromatography (HPLC). The retinol average in colostrums and mature milk in the supplemented and control groups were adequate according to the reference values. In colostrums, women from groups C, S1 and S2 presented retinol averages by milk volume of 94.8 ± 40.2 µg/dL, 92.2 ± 50.0 µg/dL and 91.8 ± 53.7 µg/dL, respectively. No difference was found between these averages (p=0.965), this was also seen when the values where expressed as µg/g of fat (p=0.905). After 30 days of delivery, retinol per milk volume differed between the control group (36.6 ± 17.5 µg/dL) and groups supplemented with 200,000 IU (51.0 ± 28.8 µg/dL) or 400,000 IU (55.2 ± 31.6 µg/dL) of retinil palmitate (p<0,05). Nevertheless, when S1 and S2 groups where compared, no significant difference was found (p=0.97). Considering retinol/g of fat, the means were 12.7 ± 6.7 µg/g, 15.6 ± 8.3 µg/g and 17.2 ± 8.9 µg/g for groups C, S1 and S2, respectively, with significant difference between groups S2 and C (p=0,01). Subclinical VAD prevalence showed a serious public health problem in the study population (32% in colostrums and 31.5% in mature milk). When analyzing the groups separately, the group which received two doses (200,000 IU + 200,000 IU) presented the lowest VAD prevalence (20.7%). Retinil palmitate supplementations of 200,000 IU and 400,000 IU (divided in two doses) in the immediate post partum showed no significant difference. Nevertheless, the 400,000 IU (divided in two doses) supplementation showed a reduction in VAD

La lenteja de parto: un recurso favorecedor de la movilidad pélvica

La lenteja de parto (LDP) supone una herramienta de ayuda para la consecución de un parto eutócico, puesto que favorece la movilidad de las articulaciones de la pelvis, la cadera y la columna, al tiempo que favorece el descenso fetal y la correcta alineación feto-pélvica. Esta herramienta presenta características similares a la pelota de parto, pudiendo ser utilizada como sustituta de ésta en ocasiones donde el uso de la pelota se puede ver limitado. No se ha demostrado ningún efecto perjudicial asociado al uso de la LDP para la madre o el recién nacido; por ello, los profesionales encargados de la atención de la gestante deben conocer las diferentes opciones y beneficios que ofrece la LDP, para ofertarla con seguridad a la mujer y optimizar sus efectos sobre el proceso del parto.

Deteção/quantificação de eritrócitos com hemoglobina fetal na gravidez e pós parto utilizando um analisador hematológico

Introdução: As células F(CF) são eritrócitos contendo hemoglobina (Hb) F e outros tipos de hemoglobina. São encontradas em indivíduos de todas as idades, ao contrário dos eritrócitos fetais, só encontrados em fetos e recém-nascidos. Nestes eritrócitos fetais, a Hb F é o tipo dominante de Hb. Estudos publicados indicam que a gravidez pode levar a um aumento progressivo de células com Hb F no sangue materno, devido à presença de CF e/ou de células fetais, estas últimas frequentemente associadas a hemorragia feto–materna (HFM). Objetivo: (1) Determinação da percentagem (%) de células com Hb F em sangue materno, usando um anticorpo Anti-Hb F num analisador hematológico. (2) Quantificação de CF e/ou células fetais na gravidez e pós o parto. (3) Elaboração de algoritmo para a triagem de HFM. Material e Métodos: Estudadas 168 amostras de sangue materno: 29 no 1º trimestre da gravidez (1ºT); 43 no segundo (2º T); 82 no terceiro (3ºT), 14 pós-parto (PP) (amostras entre dia 0 e dia 7, após parto); 32 controlos negativos (Ctl N) com homens adultos saudáveis e 30 controlos positivos (Ctl P), obtidos por mistura de sangue do cordão com sangue do adulto, AB0 compatíveis. Amostras processadas no analisador hematológico Cell-Dyn Sapphire tm, em modo RBC Flow, após ajuste de parâmetros IAS, FL1 e FL3, utilizando um reagente com iodeto de propídio e 2,5 uL de anticorpo monoclonal anti-Hb F FITC. Imagens analisadas pelo software FCS Express V3. Análise estatística com Kruskal-Wallis e teste t-Student (significância estatística p <0,05). Cut-off para HFM obtido pelo valor mínimo, em %, em que se detetam células fetais na amostra Ctl P. Resultados: foram encontradas diferenças estatisticamente significativas na % células com Hb F (P<0,0001) nos grupos estudados. % CF aumenta com a gravidez:1ºT vs Ctl N - p <0,0217 e também durante a gravidez 1ºT Vs 3ºT – P=0,0007. Mesmo depois do PP a % CF está aumentada Ctl N vs PP: - p<0,0001. Valores médios de % CF residuais em adultos saudáveis: 0,53. Maioria das amostras nos diferentes grupos estudados apresenta % CF acima do valor residual (>0,53%): 66% no grupo 1ºT, 83 % no 2º T e 91% no 3º T. Valor cut-off para suspeita de HFM de 1,70% de células com Hb F. Teste preciso (CV+- 4%) para baixas % de células com Hb F. Discussão/Conclusão: Há um aumento células com Hb F durante a gravidez e esse aumento permanece no período PP. Em duas amostras do 3ºT obteve-se % células com Hb F elevada, superior ao cut-off (≥1,70%), sendo detetada uma população de prováveis células fetais. A presença células fetais nestas amostras foi confirmada por citometria de fluxo com Anti-Hb F/ Anti-CA, com subsequente diagnóstico de HFM. Esta metodologia é simples, rápida e não dispendiosa, quando aplicada a um analisador hematológico, representa uma mais-valia no rastreio da HFM. No futuro, pode integrar o protocolo de análises de rotina das grávidas, permitindo detetar as HFM silenciosas, que são a origem de muitas anemias de causa desconhecida em recém-nascidos.

Parto prematuro: enfoques presentes en la producción científica nacional e internacional

Objetivo del estudio fue conocer la producción científica sobre el parto prematuro. Se trata de un estudio bibliográfico, realizado con 24 trabajos completos que abordan la prematuridad, derivado de la Biblioteca Virtual en Salud, publicados entre los años 2008 y 2013. El análisis de la literatura se llevó a cabo temáticamente, emergiendo cuatro categorías: factores de riesgo asociados al parto prematuro, nacimiento prematuro: Aspectos positivos y negativos; conducta profesional relacionada con el parto prematuro y el papel de la atención de enfermería en el trabajo de parto prematuro. Este estudio indica que muchos investigadores están preocupados por los factores de riesgo asociados con la prematuridad, lo que contribuye a la identificación temprana y a la reducción de las tasas de esta complicación. Aún así, son pocos los estudios que brindan contribuciones a la enfermería, dejando de contribuir al conocimiento y proceso de trabajo de estos profesionales, también responsables de producir salud en este momento de la vida de mujeres y familias que viven la prematuridad.

Indução de morte celular em células de adenocarcinoma cervical humano (HeLa) pela lectina da esponja Cinachyrella apion (CaL)

Cancer is a term used to represent a set of more than 100 diseases, including malignant tumors from different locations. The malignancies are the second leading cause of death in the population, representing approximately 17% of deaths of known cause. Strategies that induce differentiation have had limited success in the treatment of established cancers. In this work, a lectin purified from the marine sponge Cinachyrella apion (CaL) was evaluated due to its hemolytic, cytotoxic and antiproliferative properties, besides the ability to induce cell death via apoptosis in tumor cells. The antiproliferative activity of CaL was tested against cell lines, with the highest inhibition of tumor growth for HeLa, reducing cell growth at a dose dependent manner, with a concentration of 10 μg/mL. The hemolytic activity and toxicity against peripheral blood cells were tested using the concentration of IC50 for both trials and twice the IC50 for analysis in flow cytometry, indicating that CaL is not toxic to these cells. To assess the mechanism of cell death caused by CaL in HeLa cells, we performed flow cytometry and western blotting. The results showed the lectin probably induces cell death by apoptosis activation by pro-apoptotic protein Bax, promoting mitochondrial membrane permeabilization, cell cycle arrest in S phase, with accumulation of cells of approximately 57% in this phase, and acting as both dependent and/or independent of caspases pathway. These results suggest that CaL has the potential to be used as drug treatment against cancer.

Avaliação do retinol em parturientes com diabetes mellitus gestacional no pós parto imediato

Micronutrient deficiencies affect individuals mainly in developing countries, where vitamin A deficiency is a public health problem worldwide more worrying, especially in groups with increased physiological needs such as children and women of reproductive age. Vitamin A is supplied to the body through diet and has an important role in the visual process, cell differentiation, maintenance of epithelial tissue, reproductive and resistance to infection. The literature has demonstrated the relationship between vitamin A and diabetes, including gestational, leading to a risk to both mother and child. Gestational diabetes is any decrease in glucose tolerance of variable magnitude diagnosed each the first time during pregnancy, and may or may not persist after delivery. Insulin resistance during pregnancy is associated with placental hormones, as well as excess fat. Studies have shown that retinol transport protein produced in adipose tissue in high concentrations, this would be associated with resistance by interfering with insulin signaling. Therefore, this study aimed to evaluate the concentration of retinol in serum and colostrum from healthy and diabetic mothers in the immediate postpartum period. One hundred and nine parturient women were recruited, representing seventy-three healthy and thirty-six diabetic. Retinol was extracted and subsequently analyzed by High Performance Liquid Chromatography. Among the results highlights the mothers with gestational diabetes were older than mothers healthy, had more children and a higher prevalence of cases of cesarean section. Fetal macrosomia was present in 1.4% of healthy parturient women and in 22.2% of diabetic mothers. The maternal serum retinol showed an average of 39.7 ± 12.5 mg/dL for healthy parturients 35.12 ± 15 mg/dL for diabetic and showed no statistical difference. It was observed that in the group of diabetic had 17% vitamin A deficiency, whereas in the healthy group, only 4% of the women were deficentes. Colostrum, the concentration of retinol in healthy was 131.3 ± 56.2 mg/dL and 125.3 ± 41.9 mg/dL in diabetic did not differ statistically. This concentration of retinol found in colostrum provides approximately 656.5 mg/day for infants born to healthy mothers and 626.5 mg/day for infants of diabetic mothers, based on a daily consumption of 500 mL of breast milk and need Vitamin A 400 mg/day, thus reaching the requirement of the infant. The diabetic mothers showed significant risk factors and complications related to gestational diabetes. Although no 11 difference was found in serum retinol concentration and colostrum among women with and without gestational diabetes, the individual analysis shows that parturients women with diabetes are 4.9 times more likely to develop vitamin A deficiency than healthy parturients. However, the supply of vitamin A to the newborn was not committed in the presence of gestational diabetes

Avaliação da suplementação com vitamina E, na forma natural ou sintética, em mulheres no pós-parto imediato e sua concentração no colostro

The Vitamin E consists of eight chemically homologous forms, designated alpha, beta, gamma and delta tocopherols and tocotrienols. Biologically, the alpha-tocopherol (α-TOH) is the most important. Commercially, are found two types of α-TOH a natural (RRR-alpha-tocopherol) and another synthetic (all-rac-alpha-tocopherol). Both forms are absorbed in the intestine, the liver is a preference in favor of forms 2R, due to transfer protein α-TOH. It has higher affinity to these stereoisomers. Newborns are considered high risk for vitamin E deficiency, mainly premature, these have breast milk as a food source for maintenance of serum α-TOH. Clinical signs such as thrombocytosis, hemolytic anemia, retrolental fibroplasia, intraventricular hemorrhage, bronchopulmonary dysplasia and spinocerebellar degeneration can be found in case of a low intake of α-TOH. Thus, maternal supplementation on postpartum with α-TOH can be an efficient way to increase levels of vitamin E in breast milk and thus the consequently increase the supply of micronutrient for the newborn. However, most studies with vitamin E supplementation have been conducted in animals and little is known about the effect of maternal supplementation in humans, as well as on its efficiency to increase levels of α-TOH in human milk, depending on the shape natural or synthetic. The study included 109 women, divided into three groups: control without supplementation (GC) (n=36), supplemented with natural capsule (GNAT) (n=40) and the synthetic capsule (GSINT) (n=33). Blood samples were collected for determination of maternal nutritional status, and colostrums at initial contact and after 24 hours post-supplementation. Analyses were performed by High Performance Liquid Chromatography. Values of α-TOH in serum below 499.6mg/dL were considered deficient. We used the Kruskal-Wallis test and Tukey test to confirm the increase of alpha-tocopherol in milk and efficiency of administered capsules. Daily consumption of α-TOH was based on daily intake of 500 mL of colostrum by the newborn and compared with the nutritional requirement for children from 0 to 6 months of age, 4 mg / day. The mothers had mean concentration of serum α-TOH in 1016 ± 52, 1236 ± 51 and 1083 ± 61 mg / dL, in CG, GNAT and GSINT respectively. There were no women with deficiiency. The GC did not change the concentrations of α-TOH in colostrum. While women supplemented with natural and synthetic forms increased concentrations of α-TOH colostrum in 57.6% and 39%, respectively. By comparing supplemented groups, it was observed a significant difference (p=0.04), the natural capsule more efficient than the synthetic, approximately 49.6%. Individually, 21.1% of the women provided below 4mg/day of α-TOH, after supplementation for this index declined4.1%. Thus, maternal supplementation postpartum raised the levels of alpha-tocopherol in colostrum, and increased efficiency was observed with the natural form

Efecto de la ozonoterapia sobre el intervalo parto-celo y la fertilidad en vacas lecheras

En la vaca lechera la atención médica del puerperio es fundamental en los programas de manejo reproductivo. Durante este periodo se diagnostican y tratan patologías del útero con el propósito de acortar el periodo de espera voluntaria (Djuricic et al., 2012a). La ozonoterapia como medicina alternativa, es usada en tratamientos de mastitis y otros procesos infecciosos reproductivos intrauterinos (endometritis, metritis, etc.). El Ozono tiene propiedades desinfectantes, antivirales, y antibacterianas sistémicas, mejora el metabolismo celular, aumentando el número de glóbulos rojos, oxigenando mejor la sangre y aumentando la presión arterial, de esta manera la sangre pasa más rápido por las partes afectadas ejerciendo así un efecto positivo sobre los tejidos (Djuricic et al., 2012b). El objetivo del trabajo fue evaluar el efecto de la ozonoterapia sobre el intervalo parto-celo y la fertilidad de las vacas.
