Matrix proteinases in lung injury in the preterm infant

During inflammation, excess production and release of matrix proteinases, including matrix metalloproteinases (MMPs) and serine proteinases, may result in dysregulated extracellular proteolysis leading to development of tissue damage. Pulmonary inflammation may play an important role in the pathogenesis of lung injury in the preterm infant. The aims of this study were to evaluate involvement of MMPs and serine proteinase trypsin in acute and chronic lung injury in preterm infants and to study the role of these enzymes in acute lung injury by means of an animal model of hyperoxic lung injury. Molecular forms and levels of MMP-2, -8, and -9, and their specific inhibitor, tissue inhibitor of metalloproteinases (TIMP)-2, as well as trypsin were studied in tracheal aspirate fluid (TAF) samples collected from preterm infants with respiratory distress. Expression and distribution of trypsin-2 and proteinase-activated receptor 2 (PAR2) was examined in autopsy lung specimens from fetuses, from preterm infants with respiratory distress syndrome (RDS) or bronchopulmonary dysplasia (BPD), and from newborn infants without lung injury. We detected higher MMP-8 and trypsin-2 and lower TIMP-2 in TAF from preterm infants with more severe acute respiratory distress. Infants subsequently developing BPD had higher levels of MMP-8 and trypsin-2 early postnatally than did those who survived without this chronic lung injury. Immunohistochemically, trypsin-2 was mainly detectable in bronchial epithelium, but also in alveolar epithelium, and its expression was strongest in prolonged RDS. Since trypsin-2 is potent activator of PAR2, a G-protein coupled receptor involved in inflammation, we studied PAR2 expression in the lung. PAR2 co-localized with trypsin-2 in bronchoalveolar epithelium and its expression was significantly higher in bronchoalveolar epithelium in preterm infants with prolonged RDS than in newborn controls. In the experimental study, rats were exposed to >95% oxygen for 24, 48, and 60 hours, or room air. At 48 hours of hyperoxia, MMP-8 and trypsin levels sharply increased in bronchoalveolar lavage fluid, and expression of trypsin appeared in alveolar epithelium, and MMP-8 predominantly in macrophages. In conclusion, high pulmonary MMP-8 and trypsin-2 early postnatally are associated with severity of acute lung injury and subsequent development of BPD in preterm infants. In the injured preterm lung, trypsin-2 co-localizes with PAR2 in bronchoalveolar epithelium, suggesting that PAR2 activated by high levels of trypsin-2 is involved in lung inflammation associated with development of BPD. Marked increase in MMP-8 and trypsin early in the course of experimental hyperoxic lung injury suggests that these enzymes play a role in the pathogenesis of acute lung injury. Further exploration of the roles of trypsin and MMP-8 in lung injury may offer new targets for therapeutic intervention.

Long-term effects of physical activity level on changes in healthy body mass index over 12 years in young adult women

Objectives To examine the effects of overall level and timing of physical activity (PA) on changes from a healthy body mass index (BMI) category over 12 years in young adult women. Patients and Methods Participants in the Australian Longitudinal Study on Women's Health (younger cohort, born 1973-1978) completed surveys between 2000 (age 22-27 years) and 2012 (age 34-39 years). Physical activity was measured in 2000, 2003, 2006, and 2009 and was categorized as very low, low, active, or very active at each survey, and a cumulative PA score for this 9-year period was created. Logistic regression was used to examine relationships between PA accumulated across all surveys (cumulative PA model) and PA at each survey (critical periods PA model), with change in BMI category (from healthy to overweight or healthy to obese) from 2000 to 2012. Results In women with a healthy BMI in 2000, there were clear dose-response relationships between accumulated PA and transition to overweight (P=.03) and obesity (P<.01) between 2000 and 2012. The critical periods analysis indicated that very active levels of PA at the 2006 survey (when the women were 28-33 years old) and active or very active PA at the 2009 survey (age 31-36 years) were most protective against transitioning to overweight and obesity. Conclusion These findings confirm that maintenance of very high PA levels throughout young adulthood will significantly reduce the risk of becoming overweight or obese. There seems to be a critical period for maintaining high levels of activity at the life stage when many women face competing demands of caring for infants and young children.

Dietary aspects of cow's milk allergy in young children

Cow s milk allergy (CMA) affects about 2-6% of infants and young children. Environmental factors during early life are suggested to play a role in the development of allergic diseases. One of these factors is likely to be maternal diet during pregnancy and lactation. The association between maternal diet and development of CMA in offspring is not well known, but diet could contain factors that facilitate development of tolerance. After an established food allergy, another issue is gaining tolerance towards an antigen that causes symptoms. The strictness of the elimination depends on the individual level of tolerance. This study aimed at validating a questionnaire used to inquire about food allergies in children, at researching associations between maternal diet during pregnancy and lactation and subsequent development of cow s milk allergy in the offspring, and at evaluating the degree of adherence to a therapeutic elimination diet of children with CMA and factors associated with the adherence and age of recovery. These research questions were addressed in a prospective birth cohort born between 1997 and 2004 at the Tampere and Oulu University Hospitals. Altogether 6753 children of the Diabetes Prediction and Prevention (DIPP) Nutrition cohort were investigated. Questionnaires regarding allergic diseases are often used in studies without validation. High-quality valid tools are therefore needed. Two validation studies were conducted here: one by comparing parentally reported food allergies with information gathered from patient records of 1122 children, and the other one by comparing parentally reported CMA with information in the reimbursement records of special infant formulae in the registers of the Social Insurance Institution for 6753 children. Both of these studies showed that the questionnaire works well and is a valid tool for measuring food allergies in children. In the first validation study, Cohen s kappa values were within 0.71-0.88 for CMA, 0.74-0.82 for cereal allergy, and 0.66-0.86 for any reported food allergy. In the second validation study, the kappa value was 0.79, sensitivity 0.958, and specificity 0.965 for reported and diagnosed CMA. To investigate the associations between maternal diet during pregnancy and lactation and CMA in offspring, 6288 children were studied. Maternal diet during pregnancy (8th month) and lactation (3rd month) was assessed by a validated, 181-item semi-quantitative food frequency questionnaire (FFQ), and as an endpoint register-based information on diagnosed CMA was obtained from the Social Insurance Institution and complemented with parental reports of CMA in their children. The associations between maternal food consumption and CMA in offspring were analyzed by logistic regression comparing the highest and lowest quarters with two middle quarters of consumption and adjusted for several potential confounding factors. High maternal intake of milk products (OR 0.56, 95% CI 0.37-0.86 p = 0.002) was associated with a lower risk of CMA in offspring. When stratified according to maternal allergic rhinitis or asthma, a protective association of high use of milk products with CMA was seen in children of allergy-free mothers (OR 0.30, 95% CI 0.13 - 0.69, p < 0.001), but not in children of allergic mothers. Moreover, low maternal consumption of fish during pregnancy was associated with a higher risk of CMA in children of mothers with allergic rhinitis or asthma (OR 1.47, 95% CI 0.96 - 2.27 for the lowest quarter, p = 0.043). In children of nonallergic mothers, this association was not seen. Maternal diet during lactation was not associated with CMA in offspring, apart from an inverse association between citrus and kiwi fruit consumption and CMA. These results imply that maternal diet during pregnancy may contain factors protective against CMA in offspring, more so than maternal diet during lactation. These results need to be confirmed in other studies before giving recommendations to the public. To evaluate the degree of adherence to a therapeutic elimination diet in children with diagnosed CMA, food records of 267 children were studied. Subsequent food records were examined to assess the age at reintroduction of milk products to the child s diet. Nine of ten families adhered to the elimination diet of the child with extreme accuracy. Older and monosensitized children had more often small amounts of cow s milk protein in their diet (p < 0.001 for both). Adherence to the diet was not related to any other sociodemographic factor studied or to the age at reintroduction of milk products to the diet. Low intakes of vitamin D, calcium, and riboflavin are of concern in children following a cow s milk-free diet. In summary, we found that the questionnaires used in the DIPP study are valid in investigating CMA in young children; that there are associations between maternal diet during pregnancy and lactation and the development of CMA in offspring; and that the therapeutic elimination diet in children with diagnosed CMA is rigorously adhered to.

The role of androgens in fetal growth: observational study in two genetic models of disordered androgen signalling.

OBJECTIVE: To examine the role of androgens on birth weight in genetic models of altered androgen signalling. SETTING: Cambridge Disorders of Sex Development (DSD) database and the Swedish national screening programme for congenital adrenal hyperplasia (CAH). PATIENTS: (1) 29 girls with XY karyotype and mutation positive complete androgen insensitivity syndrome (CAIS); (2) 43 girls and 30 boys with genotype confirmed CAH. MAIN OUTCOME MEASURES: Birth weight, birth weight-for-gestational-age (birth weight standard deviation score (SDS)) calculated by comparison with national references. RESULTS: Mean birth weight SDS in CAIS XY infants was higher than the reference for girls (mean, 95% CI: 0.4, 0.1 to 0.7; p=0.02) and was similar to the national reference for boys (0.1, -0.2 to 0.4). Birth weight SDS in CAH girls was similar to the national reference for girls (0.0, -0.2 to 0.2) and did not vary by severity of gene mutation. Birth weight SDS in CAH boys was also similar to the national reference for boys (0.2, -0.2 to 0.6). CONCLUSION: CAIS XY infants have a birth weight distribution similar to normal male infants and birth weight is not increased in infants with CAH. Alterations in androgen signalling have little impact on birth weight. Sex dimorphism in birth size is unrelated to prenatal androgen exposure.

Impacto de la evolución científico-tecnológica en la Bioética neonatal-perinatal

Resumen: Los avances científico-tecnológicos en neonatología en los últimos 40 años han permitido una importante mejoría en la sobrevida de recién nacidos de extremo bajo peso al nacer, sin embargo la mortalidad neonatal aun representa un porcentaje muy grande de la mortalidad infantil. Esto esta principalmente relacionado a las muertes por prematuridad y sus complicaciones, anomalías congénitas y asfixia perinatal. La mayoría de los recién nacidos son tratados favorablemente en sala de partos y son admitidos a la Unidad de Cuidados Intensivos Neonatales (UCIN). La incertidumbre en el pronóstico de los prematuros extremos en el límite de la viabilidad con alto riesgo de morir en la UCIN o presentar alguna discapacidad, presenta un difícil dilema ético. Se deberá considerar cada caso en forma individual y evaluar el riesgo-beneficio entre las conductas a seguir y el “mejor interés para el niño” y los deseos de los padres que guiarán a decisiones éticas. Diferentes guías de cuidado y variaciones en la práctica médica en los límites de la viabilidad fetal se han descripto dentro y entre países. El objetivo es proveer a los padres una comunicación abierta, directa y transparente con suficiente entendimiento de los factores más relevantes en relación a la situación clínica, el pronóstico y las opciones de tratamiento para que ellos puedan tener una significativa participación en la toma de decisiones. Aceptar que en neonatología, hacer todo lo que uno puede hacer puede ser perjudicial, no útil o beneficioso. No todo lo técnicamente posible es éticamente correcto. El dilema afecta tanto al origen de la vida como a la terminación de la vida.

Interações iniciais mãe-bebê: uma comparação entre díades de bebês prematuros e nascidos a termo

O estudo das interações iniciais entre mãe e bebê é fundamental para a compreensão da ontogênese humana (Seidl-de-Moura, et al., 2008) e para ajudar a promover a saúde relacional da díade. Nos estudos sobre as interações inicias entre mãe e bebê prematuro, ainda há um questionamento sobre se o nascimento prematuro e a internação em uma UTI-Neonatal fortalecem ou enfraquecem as trocas entre os membros da díade. Assim, neste estudo observou-se e analisou-se as interações iniciais entre mãe e bebê prematuro na UTI-Neonatal, observou o desenvolvimento das interações ao longo de dois meses, e comparou com interações de um grupo de mães-bebês nascidos a termo, de acordo com categorias predefinidas para a análise de vídeos. Também analisou, através de entrevistas, as características que as mães de cada tipo de díade relataram sobre seus filhos, bem como as metas de desenvolvimento apontadas e as emoções que expressaram em relação ao bebê. Participaram da pesquisa 20 díades mãe-bebê de nascidos a termo, e 20 díades de mãebebê de prematuros, nascidos entre 28 e 36 semanas de idade gestacional. Entre outras evidências, enquanto os bebês estavam na UTI-Neonatal, foram encontradas associações significativas entre as características maternas e as do bebê. Após a alta hospitalar, houve associações significativas entre a sincronia da díade e os comportamentos dos bebês. Não houve diferenças significativas entre as características de interações quando a díade estava na UTI-Neonatal e após dois meses. Não foram observadas diferenças significativas entre as díades de mães-bebês prematuros e mães-bebês a termo em relação à sincronia da díade, nem tampouco entre os comportamentos maternos nos dois momentos de observação, mas uma diferença significativa foi encontrada entre os comportamentos autorregulatórios dos bebês nascidos a termo e os dos prematuros. Verificou-se que para os dois grupos de mães, as emoções mais frequentemente relatadas foram as de amor e apego. As metas de desenvolvimento mais apontadas enquanto as mães estavam com seu bebê na UTI-Neonatal foram voltadas para o desenvolvimento físico do bebê, e quando os bebês estavam com dois meses, as metas eram mais voltadas para o desenvolvimento emocional, da mesma forma como ocorreu com as mães de bebês a termo. As características mais apontadas pelas mães ao pensarem em seus bebês enquanto eles estavam na UTI-Neonatal foram as físicas, enquanto após a alta, foram as pessoais e emocionais, assim como ocorreu com as mães de bebês nascidos a termo. Os resultados se contrapõem a afirmações de que em episódios de interação as mães de prematuros são menos sensitivas, mais intrusivas, e seus bebês, menos atentos e responsivos. Apontaram, ao contrário, para uma certa continuidade entre o que se observou na UTI-Neonatal e aos dois meses. Também não foram identificadas diferenças significativas na maioria das características de interações entre mães e bebês prematuros e mães e bebês nascidos a termo. Assim, tais resultados suavizam possíveis estigmatizações sobre estas mães e apontam a importância de se fortalecer essa relação na UTI-Neonatal através de estratégias de promoção de saúde.

Efeitos da ingestão materna de sorbitol na lactação sobre o perfil nutricional, bioquímico e toxicológico das proles amamentadas

Sorbitol é um poliol encontrado em produtos para fins especiais, como diet e light, Dentro deste contexto, incluem-se as lactantes como grandes consumidoras, almejando o retorno mais rápido ao peso pré-gestacional. Devido à grande carência em dados referentes às consequências metabólicas do consumo excessivo destes tipos de produtos, o objetivo deste trabalho foi avaliar os possíveis efeitos da ingestão materna de sorbitol na lactação sobre os perfis nutricional, bioquímico e toxicológico nas proles amamentadas. O teste da Salmonella/microssoma foi utilizado, inicialmente, na avaliação mutagênica e citotóxica com linhagens de S. enterica sorovar Typhimurium (TA97, TA98, TA100, TA102, TA104 e TA1535). Verificamos a capacidade de reversão da mutação (I.M.) e sobrevivência (%), em diferentes concentrações (0,4; 4; 40; 400; 4000 e 5000 μg/placa). Os resultados foram considerados positivos para valores de I.M. ≥ 2,0. Ratas wistar lactantes (6 por grupo experimental), cada uma com 6 filhotes, receberam sorbitol (0,00015 mg/g/dia; 0,0015 mg/g/dia e 0,15 mg/g/dia), nos primeiros 14 dias da lactação. Neste período, avaliamos a biometria das mães e proles, consumo de ração e ingestão hídrica das mães. Após a lactação, as ratas mães foram ordenhadas, e, junto com as proles, sacrificadas por punção cardíaca, para coleta de sangue total. Os fígados das proles foram submetidos ao método de perfusão, para obtenção de hepatócitos em cultura primária, ao final dos 14 dias de lactação. Os fêmures das proles foram retirados, para obtenção da medula óssea. A bioquímica de sangue das proles (glicose, triglicerídeo, colesterol total, LDL, proteínas totais, albumina, ALT, AST, cálcio total e ionizado) foi analisada, assim como a bioquímica do leite ordenhado (triglicerídeos). Os testes do micronúcleo em medual óssea e hepatócitos, assim como o teste Cometa em sangue total, foram utilizados para avaliação genotóxica e citotóxica, de acordo com as diretrizes da OECD. Os resultados mostraram que, em concentrações mais baixas (0,00015 e 0,0015 mg/g), o sorbitol induziu o ganho de peso, principalmente na menor concentração (0,00015 mg/g), e alterações no perfil lipídico do sangue em todas as concentrações. As quantidades de triglicerídeo no leite variaram em função da dose ingerida, reduzida na maior concentração (0,15 mg/g) e aumentada na menor (0,00015 mg/g). A maior concentração (0,15 mg/g) resultou em perda de peso das mães e proles, diminuição de proteínas viscerais totais, albumina e aumento de enzimas hepáticas (ALT e AST) nas proles. Os resultados do teste da Salmonella/microssoma não indicaram mutagenicidade, entretanto, uma relação de dependência entre dose e Índice de Mutagenicidade (I.M.). Ambos os testes, micronúcleos de medula óssea e hepatócitos, apresentaram uma citotoxicidade dose dependente, estatisticamente significativa em relação ao grupo controle, corroborando com a genotoxicidade do teste Cometa e dependência de dose encontrada no teste da Salmonella/microssoma. Em concentrações mais baixas, parece existir modulação das vias lipogênicas, em contrapartida, nas mais altas a toxicidade parece dificultar tais alterações, induzindo o efeito contrário. Concluimos que o consumo excessivo de sorbitol resulta em alterações metabólicas e toxicológicas em lactentes, mesmo sendo considerado seguro pelo FDA e ANVISA.

Nutritional evaluation of some freshwater fishes

The proximate composition, amino acid composition and the PER values of Rohu (Labeo rohita), Mrigal (Cirrhina mrigala) and Calbasu (Labeo calbasu) are reported. The proximate composition of all the three fishes was similar. However the amino acid composition varied considerably. Protein quality index of the three fish proteins calculated from the amino acid composition are also reported. The nutritional quality of the 3 types of proteins to meet the growth requirements of infants, children and adult human beings is discussed. The possibility of substantial improvement in nutritional quality of the three fish proteins to suit the requirements of infants and children by marginal supplementation with valine/valine-rich food for rohu and valine and isoleucine/food rich in valine and isoleucine for mrigal and calbasu is also discussed. The results indicate that of the three fishes rohu is the best in protein quality followed by mrigal and calbasu. All of them have a better amino acid make up than casein to meet the amino acid requirement of adults.

Early biomarkers to predict grade of encephalopathy following hypoxic ischaemic injury

The standard early markers for identifying and grading HIE severity, are not sufficient to ensure all children who would benefit from treatment are identified in a timely fashion. The aim of this thesis was to explore potential early biomarkers of HIE. Methods: To achieve this a cohort of infants with perinatal depression was prospectively recruited. All infants had cord blood samples drawn and biobanked, and were assessed with standardised neurological examination, and early continuous multi-channel EEG. Cord samples from a control cohort of healthy infants were used for comparison. Biomarkers studied included; multiple inflammatory proteins using multiplex assay; the metabolomics profile using LC/MS; and the miRNA profile using microarray. Results: Eighty five infants with perinatal depression were recruited. Analysis of inflammatory proteins consisted of exploratory analysis of 37 analytes conducted in a sub-population, followed by validation of all significantly altered analytes in the remaining population. IL-6 and IL-6 differed significantly in infants with a moderate/severely abnormal vs. a normal-mildly abnormal EEG in both cohorts (Exploratory: p=0.016, p=0.005: Validation: p=0.024, p=0.039; respectively). Metabolomic analysis demonstrated a perturbation in 29 metabolites. A Cross- validated Partial Least Square Discriminant Analysis model was developed, which accurately predicted HIE with an AUC of 0.92 (95% CI: 0.84-0.97). Analysis of the miRNA profile found 70 miRNA significantly altered between moderate/severely encephalopathic infants and controls. miRNA target prediction databases identified potential targets for the altered miRNA in pathways involved in cellular metabolism, cell cycle and apoptosis, cell signaling, and the inflammatory cascade. Conclusion: This thesis has demonstrated that the recruitment of a large cohortof asphyxiated infants, with cord blood carefully biobanked, and detailed early neurophysiological and clinical assessment recorded, is feasible. Additionally the results described, provide potential alternate and novel blood based biomarkers for the identification and assessment of HIE.

Latent tuberculosis in a newborn: diagnostic challenges.

In countries where the incidence of tuberculosis is low, perinatal tuberculosis is seldom diagnosed. With increasing numbers of human immunodeficiency virus-infected people and increasing immigrant population from high tuberculosis incidence countries, one might expect perinatal tuberculosis to become more frequent. Early recognition of newborns at risk for perinatal tuberculosis infection is of utmost importance to prevent disease by chemoprophylaxis. We describe a case of latent perinatal tuberculosis infection in a newborn infected from a mother with extrapulmonary primary tuberculosis. Tuberculin skin test was negative, and latent tuberculosis infection was eventually diagnosed by specific immunological tests. We discuss the difficulties in diagnosis of recent tuberculosis infection in neonates and infants, and the risk factors for vertical transmission of tuberculosis, which need to be taken into account in considering the need for chemoprophylaxis in the newborn. Although perinatal TB infection is a rare condition and diagnosis is difficult due to poor diagnostic testing in pregnancy and newborns, a high index of suspicion is needed to limit the diagnostic delay and to avoid progression to perinatal TB disease.

Infant-nonmother interactions of free-ranging mantled howlers (Alouatta palliata) in Costa Rica

Proximate and ultimate explanations of interactions between infants and nonmothers vary depending upon the relatedness of the interactors. We investigated interactions of infants and nonmothers from a 22-month continuous study and from the long-term monitoring of the mantled howler population of La Pacifica, Guanacaste Province, Costa Rica. Relatedness is low or absent in these mantled howler groups. Juvenile females appeared to practice care skills with older infants, but as most first infants died, they failed to benefit. Infant positive interactions with adults occurred with the mother and probable father. Other adult females behaved aggressively toward the youngest infants. Mothers were retentive of infants and responded negatively to these interactions, suggesting that they perceived them as threatening. Interactions with infants appear to reflect competition in groups of unrelated adults. A review of other populations of Alouatta palliata and other species of howlers indicate variability in social group size and suggest variability in intragroup relatedness. We suggest that further study will confirm that social behavior (including interactions with infants) will vary by resource availability (group size) and associated demographic patterns (male and female migration) that affect relatedness in howler social groups.

Association of the G4 rotavirus genotype with gastroenteritis in adults

Rotavirus is the most common etiological cause of acute viral gastroenteritis in infants and young children worldwide, yet its role in the adult population is less well understood. We have recently identified rotavirus as the causative agent of severe diarrhea in adults, specifically in two gastroenteritis outbreaks in separate care for the elderly homes. Strain typing has shown the continued presence of P[8]G1, the emergence of P[8]G9, and the reemergence of P[8]G4. A total of 26 community cases and 6 outbreak cases of rotavirus infection, positive via a molecular screening assay, were subsequently amplified using VP4 and VP7 specific primers (Con2/Con3 and 1A/1B primer sets, respectively). The age range of patients investigated was from

A comparison of two measures of facial activity during pain in the newborn child

Facial activity is strikingly visible in infants reacting to noxious events. Two measures that reduce this activity to composite events, the Neonatal Facial Coding System (NFCS) and the Facial Action Coding System (FACS), were used to examine facial expressions of 56 neonates responding to routine heel lancing for blood sampling purposes. The NFCS focuses upon a limited subset of all possible facial actions that had been identified previously as responsive to painful events, whereas the FACS is a comprehensive system that is inclusive of all facial actions. Descriptions of the facial expressions obtained from the two measurement systems were very similar, supporting the convergent validity of the shorter, more readily applied system. As well, the cluster of facial activity associated with pain in this sample, using either measure, was similar to the cluster of facial activity associated with pain in adults and other newborns, both full-term and preterm, providing construct validity for the position that the face encodes painful distress in infants and adults.

Parents' experiences of caring for their infant following surgery in the neonatal period: A literature review

Previous research with parents of preterm and low-birth weight infants admitted to the Neonatal Intensive Care Unit (NICU) has indicated the following: (i) parents are at risk of experiencing stress associated with the NICU environment; (ii) parents are at risk of short- and longer-term psychological distress; and (iii) the family is at risk of longer-term stress and strain. However, parents of infants admitted to the NICU for surgery are an under-researched population. This paper provides an overview of the current literature in relation to this issue. The results highlight the paucity of research conducted with parents of infants admitted to the NICU for surgery. A number of gaps and limitations were also identified in the current literature, including a lack of examination why some parents cope better than others, and a focus solely on parents of preterm and low birth weight infants. To conclude, further research with parents of infants who had surgery in the first few weeks of life is needed. Such information could help inform clinicians caring for these infants and their families, and would enable identification of those parents and families most at risk.

Integrating elements of undergraduate curriculum learning

Integrating elements of undergraduate curriculum learning Rapidly advancing practice and recognition of nursing, midwifery and medicine as a vital interrelated workforce, implies a need for a variety of curricula opportunities. This project addresses the challenge for healthcare educators to widen student engagement and participation through inter-professional education by creating learning environments whereby student interactions foster the desire to develop situational awareness, independent learning and contribution to patient advocacy. Overall aim of this ‘Feeding and Nutrition in Infants and Children’ project is to provide opportunities for integrated learning to enable students to advance their knowledge and understanding of current best practice. This Inter-professional (IPE) student-lead workshop was initially implemented in 2006-07 in collaboration with the Centre for Excellence in IPE, within the curricula of medical and nursing programmes¹. Supported by the development of a student resource pack, this project is now being offered to Learning Disability nursing and Midwifery students since September 2014. Methods: Fourth year medical students, undertaking a ‘Child Healthcare module’, alongside nursing and /or midwifery students are divided into groups with three or four students from each profession. Each group focuses on a specific feeding problem that is scenario-based on a common real-life issue prior to the workshop and then present their findings / possible solutions to feeding problem. They are observed by both facilitators and peers, who provide constructive feedback on aspects of performance including patient safety, cultural awareness, communication, decision making skills, teamwork and an appreciation of the role of various professionals in managing feeding problems in infants and children. Results: Participants complete a Likert-scale questionnaire to ascertain their reactions to this integrated learning experience. Ongoing findings suggest that students evaluate this learning activity very positively and have stated that they value the opportunity to exercise their clinical judgement and decision making skills. Most recent comments: ‘appreciate working alongside other student’s / multidisciplinary team approach’ As a group students engage in this team problem-solving exercise, drawing upon their strengths and abilities to learn from each other. This project provides a crucial opportunity for learning and knowledge exchange for all those medical, midwifery and nursing students involved. Reference: 1.
