Hour of birth as a prognostic factor for perinatal death.

The analysis of the 220,540 births and 2152 perinatal deaths recorded in Switzerland between 1979 and 1981 showed a variation of perinatal mortality rates (PMR) according to the hour of birth. The PMR for babies born between 4 pm and 2 am was 12 per 1000, contrasting with a figure of 8.4 per 1000 for babies born between 2 am and 4 pm. This pattern, which was fairly constant throughout the week, was characterised by a slow and steady increase from the very early morning, reaching a maximum in the late evening. There was also an hour-to-hour variation in the proportion of babies born weighing less than 2500 g, with a maximum in the evening and a less pronounced peak in the morning: the mortality rates by birthweight were raised only in the evening. Since the availability of hospital staff and equipment also follows a circadian rhythm, the variation in PMR may be related to a circadian rhythm of quality of care or possibly to chronobiological or selection factors.

Diagnostic and prognostic value of cerebral 31P magnetic resonance spectroscopy in neonates with perinatal asphyxia.

The impact of depressed neonatal cerebral oxidative phosphorylation for diagnosing the severity of perinatal asphyxia was estimated by correlating the concentrations of phosphocreatine (PCr) and ATP as determined by magnetic resonance spectroscopy with the degree of hypoxic-ischemic encephalopathy (HIE) in 23 asphyxiated term neonates. Ten healthy age-matched neonates served as controls. In patients, the mean concentrations +/- SD of PCr and ATP were 0.99 +/- 0.46 mmol/L (1.6 +/- 0.2 mmol/L) and 0.99 +/- 0.35 mmol/L (1.7 +/- 0.2 mmol/L), respectively (normal values in parentheses). [PCr] and [ATP] correlated significantly with the severity of HIE (r = 0.85 and 0.9, respectively, p < 0.001), indicating that the neonatal encephalopathy is the clinical manifestation of a marred brain energy metabolism. Neurodevelopmental outcome was evaluated in 21 children at 3, 9, and 18 mo. Seven infants had multiple impairments, five were moderately handicapped, five had only mild symptoms, and four were normal. There was a significant correlation between the cerebral concentrations of PCr or ATP at birth and outcome (r = 0.8, p < 0.001) and between the degree of neonatal neurologic depression and outcome (r = 0.7). More important, the outcome of neonates with moderate HIE could better be predicted with information from quantitative 31P magnetic resonance spectroscopy than from neurologic examinations. In general, the accuracy of outcome predictability could significantly be increased by adding results from 31P magnetic resonance spectroscopy to the neonatal neurologic score, but not vice versa. No correlation with outcome was found for other perinatal risk factors, including Apgar score.

Recommendations for term and late preterm infants at risk for perinatal bacterial infection.

Since publication of the initial guidelines for the prevention of group B streptococcal disease in 1996, the incidence of perinatal infection has decreased significantly. Intrapartum antibiotic prophylaxis together with appropriate management of neonates at increased risk for early-onset sepsis not only reduces morbidity and mortality, but also decreases the burden of unnecessary or prolonged antibiotic therapy. This article provides healthcare workers in Switzerland with evidence-based and best-practice derived guidelines for the assessment and management of term and late preterm infants (>34 weeks) at increased risk for perinatal bacterial infection. Management of neonates at increased risk for early-onset sepsis depends on clinical presentation and risk factors. Asymptomatic infants with risk factors for early-onset sepsis should be observed closely in an inpatient setting for the first 48 hours of life. Symptomatic neonates must be treated promptly with intravenous antibiotics. As clinical and laboratory signs of neonatal infection are nonspecific, it is mandatory to reevaluate the need for continued antibiotic therapy after 48 hours.

Computational modeling of resting-state activity demonstrates markers of normalcy in children with prenatal or perinatal stroke.

Children who sustain a prenatal or perinatal brain injury in the form of a stroke develop remarkably normal cognitive functions in certain areas, with a particular strength in language skills. A dominant explanation for this is that brain regions from the contralesional hemisphere "take over" their functions, whereas the damaged areas and other ipsilesional regions play much less of a role. However, it is difficult to tease apart whether changes in neural activity after early brain injury are due to damage caused by the lesion or by processes related to postinjury reorganization. We sought to differentiate between these two causes by investigating the functional connectivity (FC) of brain areas during the resting state in human children with early brain injury using a computational model. We simulated a large-scale network consisting of realistic models of local brain areas coupled through anatomical connectivity information of healthy and injured participants. We then compared the resulting simulated FC values of healthy and injured participants with the empirical ones. We found that the empirical connectivity values, especially of the damaged areas, correlated better with simulated values of a healthy brain than those of an injured brain. This result indicates that the structural damage caused by an early brain injury is unlikely to have an adverse and sustained impact on the functional connections, albeit during the resting state, of damaged areas. Therefore, these areas could continue to play a role in the development of near-normal function in certain domains such as language in these children.

Maternidad tras una muerte perinatal

La nueva gestación tras una muerte perinatal está llena de dudas, miedos e inseguridades, y es una situación que va a suponer un desgaste físico y emocional para la familia, especialmente para la mujer. Esta gestación se caracteriza por un aumento de la ansiedad, que puede continuar después del nacimiento y manifestarse mediante conductas de sobreprotección del nuevo hijo. Las matronas deben conocer las posibles respuestas emocionales de la mujer y proporcionar cuidados y apoyo específicos durante el embarazo, parto y puerperio, en función de las necesidades individuales de cada familia.

Successful Surgical Pulmonary Embolectomy for Massive Perinatal Embolism after Emergency Cesarean Section.

Pregnant women are exposed to an increased risk for developing pulmonary embolism (PE), a main cause for maternal mortality. Surgical pulmonary embolectomy is one important therapeutic and potential life-saving armamentarium, considering pregnancy as a relative contraindication for thrombolysis. We present a case of a 36-year-old woman with massive bilateral PE after emergent caesarean delivery, requiring reanimation by external heart massage. The onset of massive intrauterine bleeding contraindicated thrombolysis and emergency surgical pulmonary embolectomy, followed by a hysterectomy, were preformed successfully. Acute surgical pulmonary embolectomy may be an option in critically diseased high-risk patients, requiring a multiteam approach, and should be part of the therapeutic armamentarium of the attending cardiac surgeon.

Neuronal death after perinatal cerebral hypoxia-ischemia: Focus on autophagy-mediated cell death.

Neonatal hypoxic-ischemic encephalopathy is a critical cerebral event occurring around birth with high mortality and neurological morbidity associated with long-term invalidating sequelae. In view of the great clinical importance of this condition and the lack of very efficacious neuroprotective strategies, it is urgent to better understand the different cell death mechanisms involved with the ultimate aim of developing new therapeutic approaches. The morphological features of three different cell death types can be observed in models of perinatal cerebral hypoxia-ischemia: necrotic, apoptotic and autophagic cell death. They may be combined in the same dying neuron. In the present review, we discuss the different cell death mechanisms involved in neonatal cerebral hypoxia-ischemia with a special focus on how autophagy may be involved in neuronal death, based: (1) on experimental models of perinatal hypoxia-ischemia and stroke, and (2) on the brains of human neonates who suffered from neonatal hypoxia-ischemia.

Caminador amb assistència per a persones amb mobilitat reduïda

El projecte consisteix en el disseny d’un caminador per a persones amb mobilitatreduïda. Ens hem centrat en un caminador una mica més evolucionat que els caminadorsactuals, ja que no hi ha cap aparell intermedi entre un caminador i una cadira derodes i en conseqüència moltes persones que podrien caminar si tinguessin unapetita ajuda acaben impossibilitades de ver vida en una cadira de rodes. El majorproblema de dependència d’aquestes persones és el fet d’incorporar-se del llit, sofà,lavabo i per tant el nostre disseny està pensat perquè les persones puguin feraquest pas de manera més senzilla i així augmentar la seva autonomia i autoestima.La nostra solució ha consistit en una estructura més gran que la d’un caminadornormal i que incorpori un cilindre elèctric que ajuda a la persona a aixecar-se i queno hagi de fer-ho totalment sola. Aquest mecanismes també ens serveixen per donar seguretat i evitar possibles caigudes, de manera que la persona que en fa úses pugui sentir més segura de si mateixa

Adjuvantes e assistência de ar em pulverizador de barras sobre a deposição da calda e controle de Phakopsora pachyrhizi (Sydow & Sydow)

Com o intuito de melhorar a cobertura da pulverização e diminuir as perdas na produtividade da cultura da soja, o estudo objetivou avaliar o efeito da adição de adjuvantes à calda combinado ou não ao uso da assistência de ar sobre a deposição da pulverização, controle de Phakopsora pachyrhizi H. Sydow & P. Sydow, perdas de produção (peso de 1000 grãos) e produtividade da cultura (kg ha-1). Dois experimentos a campo foram conduzidos na cultura da soja, variedade Conquista, safra agrícola 2008/09. Um deles no delineamento em blocos ao acaso com três doses de adjuvantes associados a um marcador cúprico combinadas a dois níveis de ar na barra de pulverização (0 e 29 km h-1), totalizando 6 tratamentos e 4 repetições. Outro experimento foi instalado no mesmo local do anterior. O delineamento experimental utilizado foi o de blocos ao acaso com 7 tratamentos: fungicida e dois adjuvantes associados ao fungicida, combinados a dois níveis de ar na barra de pulverização (0 e 29 km h-1), mais testemunha, e 4 repetições. Após a pulverização do fungicida piraclostrobina + epoxiconazole com diferentes tecnologias, procedeu-se a avaliação da severidade da doença através da estimativa da área abaixo da curva de progresso da doença (AACPD) e da produtividade da cultura da soja. A assistência de ar na velocidade máxima gerada pelo ventilador (29 km h-1), combinada ao fungicida piraclostrobina + epoxiconazole mais o adjuvante organosiliconado Silwet L-77 contribuiu para melhor controle da ferrugem asiática, proporcionando incremento na produtividade e no peso de 1000 grãos.
