A rare manifestation of neonatal alloimmune thrombocytopaenia
Neonatal alloimmune thrombocytopaenia (NAIT) results from a fetomaternal incompatibility with maternal sensitisation against a fetal human platelet antigen (HPA) and antibodies transfer to the fetal circulation, leading to platelet destruction. The clinical presentation is variable and isolated intraocular haemorrhage is rare. We present the case of a male newborn, with intrauterine growth restriction, born at 29 weeks due to pre-eclampsia. He presented proptosis of the left eye, hyphaema and elevated intraocular pressure, with no other signs of haemorrhage. Severe thrombocytopaenia was found (27×10(9)/L). Perinatal infection and maternal thrombocytopaenia were excluded. Positive anti-HPA-1a and antihuman leucocyte antigen class I alloantibodies were found in the mother. Platelet crossmatch between the father's platelets and mother's plasma was positive. Platelet transfusions and intravenous immunoglobulin were given with favourable response. This case highlights an unusual presentation of NAIT, which should be suspected in the presence of severe thrombocytopaenia in the first 24-72 h of life

Shotguns vs Lasers: Identifying barriers and facilitators to scaling-up plant molecular farming for high-value health products.
Plant molecular farming (PMF) is a convenient and cost-effective way to produce high-value recombinant proteins that can be used in the production of a range of health products, from pharmaceutical therapeutics to cosmetic products. New plant breeding techniques (NPBTs) provide a means to enhance PMF systems more quickly and with greater precision than ever before. However, the feasibility, regulatory standing and social acceptability of both PMF and NPBTs are in question. This paper explores the perceptions of key stakeholders on two European Union (EU) Horizon 2020 programmes-Pharma-Factory and Newcotiana-towards the barriers and facilitators of PMF and NPBTs in Europe. One-on-one qualitative interviews were undertaken with N = 20 individuals involved in one or both of the two projects at 16 institutions in seven countries (Belgium, France, Germany, Italy, Israel, Spain and the UK). The findings indicate that the current EU regulatory environment and the perception of the public towards biotechnology are seen as the main barriers to scaling-up PMF and NPBTs. Competition from existing systems and the lack of plant-specific regulations likewise present challenges for PMF developing beyond its current niche. However, respondents felt that the communication of the benefits and purpose of NPBT PMF could provide a platform for improving the social acceptance of genetic modification. The importance of the media in this process was highlighted. This article also uses the multi-level perspective to explore the ways in which NPBTs are being legitimated by interested parties and the systemic factors that have shaped and are continuing to shape the development of PMF in Europe
Ventilação não invasiva com pressão positiva intermitente - experiência de 7 anos
Introduction: Nasal intermittent positive pressure ventilation (NIPPV) is a non invasive ventilation method that combines the benefits of nasal continuous positive airway pressure (NCPAP) and the cycles of positive pressure.
Objectives: Description of the NIPPV experience in a neonatal intensive care unit.
Methods: A descriptive study of newborns ventilated with NIPPV, from January 2002 to December 2008. Were considered two groups: the first group had mechanical ventilation before NIPPV, and in the second group the initial method was non-invasive ventilation. These 2 groups were subdivided: Group 1: sub-group A, NIPPV immediately after weaning and sub- group B, NIPPV after mechanical ventilation followed by NCPAP. The group 2 was sub-divided in sub-group C, NIPPV after NCPAP, and sub-group D, NIPPV as the initial mode of ventilation.
Results: In group 1 we analysed 79 cycles of ventilation with 89% of success and in group 2 55 cycles, with 69% of success. Newborns in group 1 had a median weight of 925g and gestational age of 27 weeks and the group 2 had 1350g and 30 weeks, respectively.
Conclusions: NIPPV was used mainly after conventional ventilation in lighter and immature babies, without relevant complications
The impact of clinical pilates on quality of life and functionality of the pelvic floor in women with urinary incontinence
Urinary incontinence (UI) is considered a public health problem due to its prevalence and impact in all dimensions of health. It is consensual the positive effect of clinical Pilates on the abdominal core of healthy women, however in this type of condition there is no evidence. Objectives: To evaluate the impact of Clinical Pilates on the functionality of pelvic floor muscles and Quality of Life in women with urinary incontinence.info:eu-repo/semantics/publishedVersio

APPLICATION OF THE LINEAR SPRING-DASHPOT MODEL IN THE CFD-DEM SIMULATION OF ALUMINA FLUIDIZATION
The coupling of the Computational Fluid Dynamics (CFD) to the Discrete Element Method (DEM) to simulate fluidization is computationally demanding. Although the Linear Spring-Dahspot (LSD) model can help to reduce the CFD-DEM simulation runtime due to its simplicity, its applicability is not reasonable for all sorts of problems. The objective of the present work is to show the application of the LSD model to the CFD-DEM simulation of alumina fluidization. The simulations were carried out with the software ANSYS FLUENT 14.5 and divided into two parts: (1) the reproduction with ANSYS FLUENT of simulations from the literature in which the LSD model and a representative particle approach were used. (2) the simulation of alumina fluidization and validation with experimental data. The results of three main sets of parameters were analysed to include different DEM and CFD time steps, drag models, the representation of particles with both uniform size and particle size distribution, etc. The main conclusion of this work is that the LSD model and the CFD-DEM approach can be used to model the actual behaviour of alumina fluidized beds, but the high simulation runtime and the correct setting of the strategies used to control it are still limiting factors which deserve special attention
Síndrome de Hanhart – caso clínico
Introdução: Em 1950 Hanhart descreveu três casos de aglossia e deformidades dos membros. A associação de malformações oromandibulares e dos membros é rara, veriÞcando -se grande variabilidade fenotípica entre os casos descritos.
Caso Clínico: Gravidez com diagnóstico pré -natal ecográ-Þ co (24 semanas) de agenesia do pé direito, ausência do primeiro dedo do pé esquerdo e presença apenas da primeira falange
do primeiro e quinto dedos da mão esquerda. Às 38 semanas de gestação nasce um recém -nascido, sexo masculino, com hipotonia
generalizada e diÞ culdade respiratória com necessidade de manobras de reanimação. Ao exame físico destacava -se a presença
de microretrognatia, microstomia e várias malformações ósseas a nível das mãos e pés.
Desde as primeiras horas de vida que apresentou quadro de apneias com dessaturações recorrentes vindo a falecer na
decorrência de um desses episódios.
Discussão: A associação de microstomia, microretrognatia, hipoglossia, malformações dos membros e atingimento dos
pares cranianos, permite -nos estabelecer o diagnóstico clínico de Síndrome de Hanhart. O seu diagnóstico nem sempre é fácil,dada a grande variabilidade fenotípica
