Agreement Between Alberta Infant Motor Scale Assessment and Maternal Perception of Motor Development in Full-Term Infants.

OBJECTIVES: To verify the agreement between the Alberta Infant Motor Scale assessment and maternal perception of the motor development in full-term infants. METHODS: This is a cross-sectional study involving 161 infants and mothers. Children were assessed with the Alberta Infant Motor Scale (AIMS) for motor developmental classification. Mothers completed questionnaires aiming to identify maternal profiles and impressions about their children's development. The kappa test was used to analyze the concordance between AIMS and mother perceptions. RESULTS: A total of 83.2% of the sample was classified as typically developing and 16.8% as suspected or delayed development. The maternal impression indicates that 77% of infants are developing typically, 19.9% perceived their infants' development as advanced, and 3.1% delayed development. There was low agreement between the mothers' perceptions and AIMS classifications (kappa = 0.153). CONCLUSIONS: Maternal perception of their infant's development was unsatisfactory for evaluation of motor development because their perceptions did not agree with the findings of the AIMS.

Intra- and inter-rater reliability of a biophotogrammetric assessment protocol for preterm infants / Confiabilidade intra e interexaminador do protocolo de avaliação biofotogramétrica em prematuros

ABSTRACT Objective: To measure the intra- and inter-rater reliability of a biophotogrammetric assessment protocol for thoracoabdominal motion in preterm infants. Methods: This is an analytical cross-sectional study. Footage of 40 preterm infants was made in two views (lateral and anterior). The babies were placed in the supine position, with retroverted pelvis and semiflexed knees. Acrylic markers were positioned on surgical tape in eight predetermined anatomical points. We analyzed 4 variables in lateral view and 11 in anterior view (angular and linear) (ImageJ®), divided into two stages: 1. same frames - three blinded evaluators analyzed frames previously selected by the main researcher (inter-rater analysis 1), reviewing these same frames after 15 days (intra-rater analysis 1); 2. different frames - each evaluator selected the frames from the original video and repeated the protocol (inter-rater analysis 2), with a review after 15 days (intra-rater analysis 2). In stage 2, we tested the reliability of the entire process, from image selection to the analysis of variables. Data agreement and reproducibility were obtained by the intraclass correlation coefficient (ICC). Results: Agreement was high, particularly in angular variables (ICC 0.82 to 0.99). Linear variables ranged between very good and excellent in analysis 1 (same frames: ICC 0.64 to 0.99) and analysis 2 (different frames: ICC 0.44 to 0.89). Conclusions: The present study suggests that the proposed protocol for the thoracoabdominal motion analysis of preterm neonates has high reliability.

RESUMO Objetivo: Mensurar a confiabilidade intra e interexaminador de um protocolo de avaliação biofotogramétrica da mobilidade toracoabdominal de prematuros. Métodos: Estudo de caráter transversal e analítico. Incluíram-se filmagens de 40 prematuros em duas vistas (lateral e superior), realizadas em supino, pelve retrovertida e joelhos em semiflexão. Marcadores de acrílico foram posicionados sobre Micropores em oito pontos anatômicos predeterminados. Foram analisadas 4 variáveis na vista lateral e 11 na vista superior (angulares e lineares) (ImageJ®), divididas em duas etapas: (1-Frames iguais) análises de fotogramas previamente selecionados pela pesquisadora principal por três avaliadores cegos (análise interexaminador 1), com reanálise desses mesmos fotogramas após 15 dias (análise intraexaminador 1); (2-Frames diferentes) cada avaliador selecionou os fotogramas por meio do vídeo original e repetiu o protocolo (análise interexaminador 2), com reanálise após 15 dias (análise intraexaminador 2). Em (2), foi testada a confiabilidade de todo o processo de análise, desde a separação das imagens até a análise das variáveis. A concordância e reprodutibilidade dos dados foram obtidas pelo coeficiente de correlação intraclasse (CCI). Resultados: Houve concordância forte, com ênfase nas variáveis angulares (CCI [0,82 a 0,99]). As variáveis lineares apresentaram variação entre muito boa e excelente na análise 1 (frames iguais: CCI 0,64 a 0,99) e na análise 2 (frames diferentes: CCI entre 0,44 e 0,89). Conclusões: O presente estudo sugere forte confiabilidade do protocolo proposto para análise da movimentação toracoabdominal de neonatos prematuros.

Temporal assessment of neonatal pain after airway aspiration. / Avaliação temporal da dor neonatal após aspiração de vias aéreas.

OBJECTIVE: To temporally assess a painful stimulus in premature infants using 3 neonatal pain scales. METHODS: A total of 83 premature infants were observed during airway aspiration by 3 evaluators (E1, E2 and E3) using 3 pain assessment scales (Neonatal Facial Coding System - NFCS; Neonatal Infant Pain Scale - NIPS; and Premature Infant Pain Profile - PIPP) at 5 time points: T1 (before airway aspiration), T2 (during airway aspiration), T3 (1 minute after airway aspiration), T4 (3 minutes after airway aspiration), and T5 (5 minutes after airway aspiration). Light's Kappa (agreement among examiners and among scales at each time point) and the McNemar test (comparison among time points) were used considering p < 0.05. RESULTS: There was a significant difference between the 3 examiners for T1 and T2 using the 3 scales. In T3, pain was observed in 22.9%/E1, 28.9%/E2, and 24.1%/E3 according to the NFCS; 22.9%/E1, 21.7%/E2, and 16.9%/E3 according to the NIPS; and 49.4%/E1, 53.9%/E2, and 47%/E3 according to the PIPP. There was a difference between T1 and T3 using the 3 scales, except for 2 examiners for the PIPP (E2: p = 0.15/E3: p = 0.17). Comparing T4 and T5 to T1, there was no difference in the 3 scales. CONCLUSION: Premature infants required at least 3 minutes to return to their initial state of rest (no pain).

RESUMO Objetivo: Avaliar temporalmente o estímulo doloroso em prematuros com o uso de três escalas de mensuração de dor neonatal. Métodos: Foram observados 83 prematuros durante a aspiração de vias aéreas por três avaliadores (E1, E2 e E3) utilizando três escalas de avaliação da dor (Neonatal Facial Coding System - NFCS; Neonatal Infant Pain Scale - NIPS; e Premature Infant Pain Profile - PIPP) em cinco momentos: T1 (antes da aspiração de vias aéreas), T2 (durante a aspiração de vias aéreas), T3 (1 minuto após a aspiração de vias aéreas), T4 (3 minutos após a aspiração de vias aéreas) e T5 (5 minutos após a aspiração de vias aéreas). Utilizaram-se o Light's Kappa (concordância entre examinadores e entre as escalas em cada tempo) e teste de McNemar (comparação entre os tempos), considerando-se p < 0,05. Resultados: Houve diferença significativa entre T1 e T2 para os três examinadores nas três escalas. Em T3, observou-se dor em 22,9%/E1, 28,9%/E2 e 24,1%/E3 de acordo com a NFCS; 22,9%/E1, 21,7%/E2 e 16,9%/E3, conforme a NIPS e 49,4%/E1, 53,9%/E2 e 47%/E3 considerando a PIPP dos prematuros. Houve diferença entre T1 e T3 nas três escalas, exceto para dois examinadores na PIPP (E2: p = 0,15/ E3: p = 0,17). Ao comparar T4 e T5 ao T1, não houve diferença em nenhuma das três escalas. Conclusão: Os prematuros necessitaram de pelo menos 3 minutos para retornarem ao seu estado inicial de repouso (sem dor).

NEONATAL PAIN: CHARACTERIZATION OF THE PHYSIOTHERAPIST'S PERCEPTION IN THE NEONATAL INTENSIVE CARE UNIT.

OBJECTIVE: To describe the perception of physiotherapists in neonatal units regarding pain, the use of measurement scales and strategies that minimize pain. METHODS: Interviews were conducted with physiotherapists in hospitals with neonatal units between 2013 and 2015 in Rio de Janeiro. The questions concerned the knowledge of the feeling of pain, from its recognition to its care or treatment. The description of the results was done by comparing public and private hospitals (Fisher''s Exact exact Testtest), considering p<0.05 as significant. RESULTS: 27 hospitals were visited. All the professionals interviewed (n=27) stated that the newborns feel pain, with facial expression being the most cited and known sign for pain. 26% of physiotherapists believe that newborns experience pain at the same magnitude as adults. Among the scales, the Neonatal Infant Pain Scale (NIPS) was the most well known, but only 37% of the units had routine pain assessment protocols. IV cannulation and blood collection were the most mentioned procedures as a cause of pain and there was no difference between public and private hospitals. CONCLUSIONS: There is a gap in the knowledge about neonatal pain and how to evaluate it among the participating physiotherapists, with no systematization of care routines involving this assessment.

RESUMO Objetivo: Descrever a percepção dos fisioterapeutas de unidades neonatais sobre a dor, a utilização de escalas de mensuração e estratégias que a minimizem. Métodos: Entrevistas foram realizadas com chefes ou rotinas de fisioterapia em hospitais com unidades neonatais entre 2013 e 2015, no Rio de Janeiro. As perguntas versaram sobre o conhecimento da sensação dolorosa, desde seu reconhecimento até seu cuidado ou tratamento. Foi realizada a descrição dos resultados, comparando-se os dados dos hospitais públicos com os privados (teste exato de Fisher), considerando-se p<0,05 como significante. Resultados: Vinte e sete hospitais foram visitados. Todos os profissionais entrevistados (n=27) afirmaram que os recém-nascidos sentem dor, sendo a expressão facial o sinal de dor mais conhecido. Do total de fisioterapeutas entrevistados, 26% acreditam que os neonatos sentem dor na mesma magnitude que o adulto. Entre as escalas, a Neonatal Infant Pain Scale (NIPS) era a mais conhecida, e apenas 37% das unidades possuíam protocolos de avaliação da dor na rotina. As coletas e as punções foram os procedimentos mais mencionados como causa de dor, e não houve diferença entre os hospitais públicos e privados. Conclusões: Constatou-se uma lacuna no conhecimento sobre dor neonatal e como avaliá-la entre os fisioterapeutas participantes, com ausência de sistematização de rotinas assistenciais que envolvam essa aferição.

Benefícios da inserção do fisioterapeuta sobre o perfil de prematuros de baixo risco internados em unidade de terapia intensiva / Beneficios de la inserción del fisioterapeuta sobre el perfil de prematuros de bajo riesgo internados en unidad de terapia intensiva / Benefits of inserting the physical therapist on the profile of low-risk premature infants admitted to an intensive care unit

RESUMO O presente estudo visa descrever os benefícios da inserção do fisioterapeuta sobre o perfil de prematuros de baixo risco internados em unidade de terapia intensiva neonatal. Estudo caso-controle, retrospectivo, com consulta aos prontuários de prematuros internados em 2006/2007 sem fisioterapia (PREF) e em 2009/2010 com fisioterapia por até 8h/dia (POSF). Incluíram-se 61 prematuros no período PREF e 93 no POSF, nascidos com ≥1000g, SNAP-PE II <40, com tempo de suporte ventilatório ≥24h. Verificou-se os perfis materno e dos neonatos, tempos de internação, de ventilação mecânica invasiva e não invasiva e de oxigenoterapia. Realizou-se análise descritiva, teste Mann Whitney, teste t, qui-quadrado e Fisher, considerando-se p≤0,05. Houve diferença significativa entre as idades gestacionais [PREF: 230,5 (±16,5)/ POSF: 226 (±15); p=0,05], frequência de sepse [PREF: 6 (10%)/ POSF: 30 (32%); p<0,01], de síndrome do desconforto respiratório [PREF: 11(18%)/ POSF: 43 (46%); p<0,01], necessidade de reanimação na sala de parto [PREF: 10 (16%)/ POSF: 32 (34%); p=0,02], necessidade de intubação orotraqueal [PREF: 8 (13%)/ POSF: 26 (28%); p=0,05], tempo de ventilação não invasiva (PREF: 0,1±0,4 dias/ POSF: 0,8±2,3 dias; p<0,01), de ventilação invasiva (PREF: 0,4±1,3 dias/ POSF: 1,3±3,3 dias; p=0,04), de pressão positiva contínua em vias aéreas (PREF: 1,5±1,0 dias/ POSF: 2,7±3,8 dias; p=0,04). A presença do fisioterapeuta gerou benefícios, contribuindo para a manutenção dos tempos de internação e de oxigenoterapia mesmo diante de um perfil de recém-nascidos mais imaturos e com mais intercorrências no período após a inserção da fisioterapia.

La presencia del fisioterapeuta generó beneficios, contribuyendo para el mantenimiento de los tiempos de internación y de oxigenoterapia, aunque el perfil de recién nacidos tuvo más intercurrencias después de la inserción de la fisioterapia.

ABSTRACT This study aims to describe the benefits of inserting the physical therapist on the profile of low-risk premature infants in neonatal intensive care units. This is a retrospective control study, with consultation to the medical records of premature infants admitted in 2006/2007 without physical therapy (PREP) and in 2009/2010 with physical therapy for up to 8h/day (POSTP). 61 preterm infants in the PREP period and 93 in the POSTP were included, born with ≥1000g, SNAP-PE II <40, with a duration of ventilatory support ≥24h. Maternal and neonatal profiles, duration of hospitalization, invasive and non-invasive mechanical ventilation and oxygen therapy were verified. Descriptive analysis, the Mann Whitney test, t-test, Chi-squared and Fisher's test were performed, considering p≤0.05. There was a significant difference between gestational ages [PREP: 230.5 (±16.5)/POSTP: 226 (±15); p = 0.05], frequency of sepsis [PREP: 6 (10%) / POSTP: 30 (32%); p < 0.01], respiratory distress syndrome [PREP: 11 (18%)/POSTP: 43 (46%); p < 0.01], need for resuscitation in the delivery room [PREP: 10 (16%) / POSTP: 32 (34%); p = 0.02], need for orotracheal intubation [PREP: 8 (13%)/POSTP: 26 (28%); invasive ventilation (PREP: 0.4±1.3 days/POSTP: 1.3±3.3 days, p = 0.04), continuous positive airway pressure (PREP: 1.5±1.0 days/POSTP: 2.7±3.8 days, p = 0.04). The presence of the physical therapist generated benefits, contributing to the maintenance of the length of hospitalization and oxygen therapy in face of a profile of more immature newborns and with more complications in the period after physical therapy was inserted.

Harmonization of light scatter and fluorescence flow cytometry profiles obtained after staining peripheral blood leucocytes for cell surface-only versus intracellular antigens with the Fix & Perm reagent.

Staining for intracellular markers with the Fix & Perm reagent is associated with variations in the scatter properties of leucocytes, limiting automated analysis of flow cytometry (FCM) data. Here, we investigated those variables significantly contributing to changes in the light scatter, autofluorescence, and bcl2 staining characteristics of peripheral blood (PB) leucocytes, after fixation with Fix & Perm. Our major aim was to evaluate a new mathematical approach for automated harmonization of FCM data from datafiles corresponding to aliquots of a sample treated with cell-surface-only versus Fix & Perm intracellular staining techniques. Overall, neither the anticoagulant used nor sample storage for <24 h showed significant impact on the light scatter and fluorescence properties of PB leucocytes; similarly, the duration of the fixation period (once >15 min were used) had a minimum impact on the FCM properties of PB leucocytes. Conversely, changes in cell/protein concentrations and the fixative/sample (vol/vol) ratio had a clear impact on the light scatter features of some populations of leucocytes. Accordingly, lower cell/protein concentrations were associated with lower scatter values, particularly for the neutrophils. Such changes could be partially corrected through the use of higher fixative to sample volume ratios. Despite the variable changes detected between aliquots of the same sample treated with cell surface-only versus intracellular staining procedures, the new mathematical approach here proposed and evaluated for automated harmonization of common parameters in both datafiles, could correct the FCM profiles of leucocytes derived from cells undergoing conventional fixation/permeabilization procedures, and made them indistinguishable from those corresponding to aliquots of the same sample treated with cell-surface-only staining techniques.
