Black/white disparities in infant mortality rates in the U.S.: A quality of care perspective

The infant mortality rate for non-Hispanic Black infants in the U.S. is 13.63 deaths per 1,000 live births while the IMR for non-Hispanic White persons in the U.S. is 5.76 deaths per 1,000 live births. Black women are 2 times as likely as White women to deliver preterm infants and Black women are 2 times as likely as White women to deliver low birth weight infants (weighing less than 2,500 grams at birth). Differential underlying risk factors among mothers of different racial/ethnic groups for delivering pre-term and low birth weight infants have been historically accepted as the cause of racial disparities in IMRs. However, differential underlying risk status may not be the only major causative factor. Differential or unequal access to and provision of care is widely speculated to be a leading contributing factor to the wide racial disparity in infant mortality.2 This paper conducts a systematic review of existing literature investigating racial disparities in obstetrical care provided by healthcare practitioners to evaluate whether inequities in healthcare services provided to pregnant mothers and their neonates exist. The search terms "racial disparities obstetrical care," "racial differences quality of prenatal care," and "infant mortality racial disparities" were entered into the EBSCO Medline, Ovid Medline, PubMed, and Academic Search Complete databases, and articles between years 1990–2011 were selected for abstract review. The only articles included were those that used statistical methods to assess whether racial inequalities were present in the obstetrical services provided to pregnant women. My literature search returned 5 articles. Four of the five studies yielded significant racial differences in obstetrical care. However, the one study that used a large, nationally representative valid sample did not represent significant differences. Thus, this review provides initial evidence for racial disparities in obstetrical care, but concludes that more studies are needed in this area. Not all of the studies reviewed were consistent in the use and measurement of services, and not all studies were significant. The policy and public health implications of possible racial disparities in obstetrical care include the need to develop standard of care protocols for ALL obstetrical patients across the United States to minimize and/or eliminate the inequities and differences in obstetrical services provided.^

Abolition of morphine-immunosuppression in mice lacking the μ-opioid receptor gene

Opiates are potent analgesic and addictive compounds. They also act on immune responses, and morphine, the prototypic opiate, has been repeatedly described as an immunosuppressive drug. Pharmacological studies have suggested that the inhibitory action of opiates on immunity is mediated by multiple opioid receptor sites but molecular evidence has remained elusive. Recently, three genes encoding μ- (MOR), δ-, and κ-opioid receptors have been cloned. To investigate whether the μ-opioid receptor is functionally implicated in morphine immunosuppression in vivo, we have examined immune responses of mice with a genetic disruption of the MOR gene. In the absence of drug, there was no difference between wild-type and mutant mice with regard to a large number of immunological endpoints, suggesting that the lack of MOR-encoded protein has little consequence on immune status. Chronic morphine administration induced lymphoid organ atrophy, diminished the ratio of CD4+CD8+ cells in the thymus and strongly reduced natural killer activity in wild-type mice. None of these effects was observed in MOR-deficient mice after morphine treatment. This demonstrates that the MOR gene product represents a major molecular target for morphine action on the immune system. Because our previous studies of MOR-deficient mice have shown that this receptor protein is also responsible for morphine analgesia, reward, and physical dependence, the present results imply that MOR-targeted therapeutic drugs that are developed for the treatment of pain or opiate addiction may concomitantly influence immune responses.

Nociception in cyclooxygenase isozyme-deficient mice

Prostaglandins formed by cyclooxygenase-1 (COX-1) or COX-2 produce hyperalgesia in sensory nerve endings. To assess the relative roles of the two enzymes in pain processing, we compared responses of COX-1- or COX-2-deficient homozygous and heterozygous mice with wild-type controls in the hot plate and stretching tests for analgesia. Preliminary observational studies determined that there were no differences in gross parameters of behavior between the different groups. Surprisingly, on the hot plate (55°C), the COX-1-deficient heterozygous groups showed less nociception, because mean reaction time was longer than that for controls. All other groups showed similar reaction times. In the stretching test, there was less nociception in COX-1-null and COX-1-deficient heterozygotes and also, unexpectedly, in female COX-2-deficient heterozygotes, as shown by a decreased number of writhes. Measurements of mRNA levels by reverse transcription–PCR demonstrated a compensatory increase of COX-1 mRNA in spinal cords of COX-2-null mice but no increase in COX-2 mRNA in spinal cords of COX-1-null animals. Thus, compensation for the absence of COX-1 may not involve increased expression of COX-2, whereas up-regulation of COX-1 in the spinal cord may compensate for the absence of COX-2. The longer reaction times on the hot plate of COX-1-deficient heterozygotes are difficult to explain, because nonsteroid anti-inflammatory drugs have no analgesic action in this test. Reduction in the number of writhes of the COX-1-null and COX-1-deficient heterozygotes may be due to low levels of COX-1 at the site of stimulation with acetic acid. Thus, prostaglandins made by COX-1 mainly are involved in pain transmission in the stretching test in both male and female mice, whereas those made by COX-2 also may play a role in the stretching response in female mice.

Respiratory effects of dexmedetomidine in the surgical patient requiring intensive care

The respiratory effects of dexmedetomidine were retrospectively examined in 33 postsurgical patients involved in a randomised, placebo-controlled trial after extubation in the intensive care unit (ICU). Morphine requirements were reduced by over 50% in patients receiving dexmedetomidine. There were no differences in respiratory rates, oxygen saturations, arterial pH and arterial partial carbon dioxide tension (PaCO2) between the groups. Interestingly the arterial partial oxygen tension (PaO2) : fractional inspired oxygen (FIO2) ratios were statistically significantly higher in the dexmedetomidine group. Dexmedetomidine provides important postsurgical analgesia and appears to have no clinically important adverse effects on respiration in the surgical patient who requires intensive care.

Tonic nicotinic modulation of serotoninergic transmission in the spinal cord

The spinal serotoninergic projection from the raphe magnus has been shown to modulate nociceptive inputs, and activation of this projection mediates nicotine-elicited analgesia. Here, we investigate the interactions between cholinergic and serotoninergic systems in the spinal cord, by conducting serotonin [5-hydroxytryptamine (5-HT)] efflux experiments on mouse spinal slices. At least three spinal populations of nicotinic receptors are distinguished that affect 5-HT release. The first could be directly located on serotoninergic terminals, is insensitive to nanomolar concentrations of methyllicaconitine (MLA), and may be subjected to a basal (not maximal) cholinergic tone. The second is tonically and maximally activated by endogenous acetylcholine, insensitive to nanomolar concentrations of MLA, and present on inhibitory neurons. The last is also present on inhibitory neurons but is sensitive to nanomolar concentrations of MLA and not tonically activated by acetylcholine. Multiple nicotinic acetylcholine receptor populations thus differentially exert tonic or not tonic control on 5-HT transmission in the spinal cord. These receptors may be major targets for nicotine effects on antinociception. In addition, the presence of a tonic nicotinic modulation of 5-HT release indicates that endogenous acetylcholine plays a role in the physiological regulation of descending 5-HT pathways to the spinal cord.

Promoção, comunicação e educação em saúde: a prática da acupuntura e da fitoterapia

Esta pesquisa discute a Comunicação em Saúde no contexto das Práticas Integrativas e Complementares (PIC) no Sistema Único de Saúde (SUS), no que concerne ao tratamento do câncer realizado num hospital público de Campinas. O arcabouço teórico se debruça sobre as diretrizes do ideário da Promoção da Saúde e sobre as discussões da Educação em Saúde, por serem premissas fundamentais para que a Comunicação em Saúde seja participativa e democrática, e que a Comunicação das PIC conquiste maior espaço na Saúde Pública. O objetivo geral foi investigar o processo de comunicação entre profissionais de saúde e usuários do SUS participantes do Projeto de Construção do Cuidado Integrativo (PCCI). A metodologia utilizada foi a qualitativa tendo como instrumentos pesquisa documental e entrevistas semi-estruturadas para a coleta dos dados. Os participantes do estudo foram usuários que fizeram parte do grupo de Acupuntura e de Fitoterapia e usaram práticas complementares ao tratamento convencional do câncer, e também os profissionais de saúde envolvidos no PCCI realizado no Hospital de Clínicas da Universidade Estadual de Campinas (UNICAMP)/SP. Os dados foram analisados por meio da análise temática de conteúdo de Bardin, que permitiu identificar as seguintes categorias: Medo da intervenção, Analgesia como resultado, Continuidade do tratamento, Falta de informação e Divulgação das práticas. Os resultados mostraram que houve dificuldades de comunicação, indicando lacunas importantes em relação à infraestrutura, à falta de divulgação e continuidade do tratamento complementar com as PIC, a falta de valorização da participação popular e estímulo à autonomia como preconiza o ideário da Promoção da Saúde. Concluiu-se que o modelo de saúde vigente, de base biomédica, não tem permitido a participação dos usuários, e, mais ainda, tem dificultado o desenvolvimento da comunicação democrática, humanizada e solidária. O Projeto (PCCI) foi importante em sua execução, uma vez que trouxe resultados positivos com o uso das PIC por melhorar as condições da qualidade de vida dos usuários e ter promovido analgesia, conferido maior disposição e recuperação dos movimentos. Entretanto, o Projeto (PCCI) não teve potencial o suficiente para provocar uma mudança na lógica do tratamento convencional que está hegemonicamente imerso no modelo biomédico, com isso limitando a inserção e a comunicação das PIC na Saúde Pública e dificultando a abertura para o diálogo entre os diferentes saberes. Entende-se que este é um dos principais desafios da Medicina Tradicional e Complementar (MTC).

Inequality in analgesic prescription in Spain: a gender development issue

Objectives: It is well known that sex differences in analgesic prescription are not merely the logical result of greater prevalence of pain in women, since this therapeutic variability is related to factors such as educational level or social class. This study aims to analyse the relationship between analgesic prescription and gender development in different regions of Spain. Methods: Cross-sectional study of sex-differences in analgesic prescription according to the gender development of the regions studied. Analgesic prescription, pain and demographic variables were obtained from the Spanish Health Interview Survey in 2006. Gender development was measured with the Gender Development Index (GDI). A logistic regression analysis was conducted to compare analgesic prescription by sex in regions with a GDI above or below the Spanish average. Results: Once adjusted by pain, age and social class, women were more likely to be prescribed analgesics than men, odds ratio (OR) = 1.74 (1.59-1.91), as residents in regions with a lower GDI compared with those in region with a higher GDI: ORWomen = 1.26 (1.12-1.42), ORMen = 1.30 (1.13-1.50). Women experiencing pain in regions with a lower GDI were more likely than men to be treated by a general practitioner rather than by a specialist, OR = 1.32 (1.04-1.67), irrespective of age and social class. Conclusions: Gender bias may be one of the pathways by which inequalities in analgesic treatment adversely affect women's health. Moreover, research into the adequacy of analgesic treatment and the possible medicalisation of women should consider contextual factors, such as gender development.

Paracetamol vs ibuprofeno para el dolor de la episiotomía en las 42 horas postparto

Objetivo: Evaluación de la eficacia analgésica para el dolor de la episiotomía entre el paracetamol y el Ibuprofeno, en las primeras 42 horas postparto. Método: Estudio cuasi-experimental (prospectivo y simple ciego) en mujeres que dieron a luz en el HOSPITAL UNIVERSITARIO CENTRAL DE ASTURIAS (OVIEDO), excluyendo alérgicas, patologías asociadas ó aquellas que el idioma impidiese un correcto entendimiento. Dos grupos: 1) Paracetamol 1 gr; 2) Ibuprofeno 600 mg. Tamaño de muestra: 110 por grupo para alcanzar mínimo de 80. Variable principal: grado de dolor según puntuación de escala (0 a 3). Otras variables: edad de paciente, semanas de gestación, peso neonatal, paridad, inicio del parto, anestesia epidural, tipo de parto, desgarro, inflamación y enrojecimiento, hematoma, hemorroides, necesidad de sondaje evacuador, aplicación de hielo y solicitud de analgesia. Tamaño final de la muestra: 88 grupo paracetamol y 97 grupo ibuprofeno. La escala de dolor se midió a las 2 horas postparto (previo al tratamiento) y, posteriormente, cada 8 hasta 42 horas. Se realizó análisis descriptivo y comparación entre grupos. Resultados: No encontramos diferencias significativas en la escala de dolor entre ambos fármacos, ni en los subgrupos analizados, salvo en el subgrupo de partos eutócicos, donde el ibuprofeno fue superior al paracetamol. En el global de la serie, el grupo de paracetamol solicitó hielo y otra medicación con mayor frecuencia que el grupo de ibuprofeno. Conclusiones: El ibuprofeno 600 mg y el paracetamol de 1 gr obtienen una respuesta similar en las primeras 42 horas postparto, si bien el ibuprofeno parece tener algunas ventajas adicionales.

Donación voluntaria de sangre de cordón umbilical en el Hospital Universitario Virgen de la Arrixaca (2010-2011). Situación actual e influencia de las variables obstétrico-fetales

Objetivos: A principios de 2010 el Hospital Universitario Virgen de la Arrixaca puso en marcha, en el servicio de partos, el protocolo de donación voluntaria de sangre de cordón umbilical (SCU). Desde la reflexión y la autoevaluación, planteamos un análisis de nuestra situación actual a través del estudio de la influencia de las variables obstétrico-fetales en la calidad de las muestras. Métodos: Con este fin hemos planteado un trabajo de tipo observacional, descriptivo, retrospectivo y de corte transversal desde mayo de 2010 a noviembre de 2011, con el objetivo de aumentar la calidad de las unidades de SCU y optar por una gestión eficiente que haga sostenible el proyecto. Resultados: Se obtuvieron 123 donaciones potenciales de sangre de cordón y del análisis multivariable de las mismas obtuvimos una correlación positiva significativa entre el número de leucocitos, las semanas de gestación y el parto vaginal. El peso inicial de la unidad se incrementó significativamente a mayor peso del recién nacido y paridad de la donante. Conclusiones: Como conclusiones del estudio nos planteamos esbozar posibles factores predictivos que permitan seleccionar las muestras de mayor calidad y sean complemento de los actuales estándares elaborados por el Banco Público de Málaga. En este sentido nuestros resultados sugieren que en los partos con más semanas de gestación, paridad de la gestante y peso del recién nacido, así como en los partos vaginales, encontramos mayores posibilidades de obtener muestras de alta calidad.

O Contributo dos Fatores Psicológicos na Ocorrência do Parto Pré-termo

Some psychological variables of women seem to be in close relationship with the clinical course of pregnancy and delivery outcome. However, about risk factors for preterm birth, it is necessary to deepen the knowledge of the psychological risk area to enable more effective prevention. Aim: To relate the result of delivery, with regard to gestational age, mode of delivery and infant characteristics with psychological variables assessed during pregnancy, prenatal maternal attachment, psychopathological symptomatology and coping. Methodology: A prospective, descriptive correlational study; participants were 395 women at the second trimester of pregnancy and at postpartum, who attended antenatal clinics at the center of Portugal. The following instruments were used: Clinical Questionnaire about the Result of Delivery; Sociodemographic and Clinical Questionnaire in Pregnancy; Maternal Antenatal Attachment Scale; Brief Symptoms Inventory (BSI); Problems’ Resolution Inventory (PRI). Results: Gestational age and birth weight of the baby, on one side, and variables of prenatal attachment, BSI and PRI, on the other side, did not correlate significantly. The quality of prenatal maternal attachment was higher in women who came to have a delivery by forceps or vacuum extraction, compared with those that had caesarean birth (p = .05). The majority of women had a healthy pregnancy (75.7%). Coping strategies like Interpersonal Sensitivity and Help-seeking seem to influence the occurrence of obstetrical pathology. Women with higher scores on Total Prenatal Attachment and Intensity of Preocupation are more likely to have newborns with health problems. There is an association between clinical variables, the newborn´s health at birth and obstetric pathology of the II and III trimesters. Conclusion: Prenatal psychological factors such as prenatal attachment do not seem to influence the obstetric condition or the result of delivery but appear to play an important role about how pregnant women experience pregnancy and labor.
