AC-ASPECTS, ACh-ASPECTS, and H-ASPECTS: new imaging scales to assess territorial and total cerebral hemispheric ischemic injury.

Background: The extent of ischemic injury in acute stroke is assessed in clinical practice using the Acute Stroke Prognosis Early CT Score (ASPECTS) rating system. However, current ASPECTS semi-quantitative topographic scales assess only the middle cerebral artery (MCA) (original ASPECTS) and posterior cerebral (PC-ASPECTS) territories. For treatment decision-making in patients with anterior cerebral artery (ACA) occlusions and internal carotid artery (ICA) occlusions with large ischemic cores, measures of all hemispheric regions are desirable. Methods: In this cohort study, anatomic rating systems were developed for the anterior cerebral (AC-ASPECTS, 3 points) and anterior choroidal artery (ACh-ASPECTS, 1 point) territories. In addition, a total supratentorial hemisphere (H-ASPECTS, 16 points) score was calculated as the sum of the MCA ASPECTS (10 regions), supratentorial PC-ASPECTS (2 regions), AC-ASPECTS (3 regions), and ACh-ASPECTS (1 region). Three raters applied these scales to initial and 24 h CT and MR images in consecutive patients with ischemic stroke (IS) due to ICA, M1-MCA, and ACA occlusions. Results: Imaging ratings were obtained for 96 scans in 50 consecutive patients with age 74.8 (±14.0), 60% female, NIHSS 15.5 (9.25-20), and occlusion locations ICA 34%; M1-MCA 58%; and ACA 8%. Treatments included endovascular thrombectomy +/- thrombolysis in 72%, thrombolysis alone in 8%, and hemicraniectomy in 4%. Among experienced clinicians, inter-rater reliability for AC-, ACh-, and H-ASPECTS scores was substantial (kappa values 0.61-0.80). AC-ASPECTS abnormality was present in 14% of patients, and ACh-ASPECTS abnormality in 2%. Among patients with ACA and ICA occlusions, H-ASPECTS scores compared with original ASPECTS scores were more strongly associated with disability level at discharge, ambulatory status at discharge, discharge destination, and combined inpatient mortality and hospice discharge. Conclusion: AC-ASPECTS, ACh-ASPECTS, and H-ASPECTS expand the scope of acute IS imaging scores and increase correlation with functional outcomes. This additional information may enhance prognostication and decision-making, including endovascular thrombectomy and hemicraniectomy.

Canadian and Brazilian Percentile Ranks for the Alberta Infant Motor Scale.

Aim: To verify if there is a difference between the percentile ranks for Brazilian infants compared with norms for Canadian infants on the Alberta Infant Motor Scale (AIMS). Method: A cross-sectional study in which 322 Brazilian infants, 2 to 15 months old, were administered the AIMS. Percentile ranks were calculated using norms for Canadian infants and norms from two studies of Brazilian infants. The Friedman test compared the AIMS percentile ranks for the entire sample. For reliability analysis, the interclass correlation coefficient (ICC) was used. Bland Altman's analysis was applied to compare percentile ranks. Results: Of the 322 evaluations analyzed, there were significant differences (p<.001) between the three percentile ranks compared. The Canadian norms presented the lowest average rating. There was good reliability between the percentile ranks (ICC > 0.75) but low agreement (Bland Altman; p<.001). Conclusion: There are differences between the Brazilian and Canadian percentile ranks and between the Brazilian percentile ranks of 2014 and 2016, and these differences may influence identification of motor development.

Reliability and accuracy of individual Alberta Stroke Program Early CT Score regions using a medical and a smartphone reading system in a telestroke network.

INTRODUCTION: The aim of this study was to assess individual regions of the Alberta Stroke Program Early CT Score in noncontrast head computed tomography interpretations using a smartphone in a telestroke network, by comparison to a medical monitor. METHODS: The review board of our institution approved this retrospective study. A factorial design with 188 patients, four radiologists and two reading systems was used. Accuracy and reliability were evaluated. RESULTS: Very good interobserver agreements were observed on the total Alberta Stroke Program Early CT Score for both the medical and smartphone reading systems, with intraclass correlation coefficients of 0.91 and 0.84 respectively. Interobserver agreements were moderate to very good for the medical reading system (all intraclass correlation coefficients >0.74), whereas they were fair to very good for the smartphone (intraclass correlation coefficients ranged from 0.31-0.81). All intraobserver agreements were good (intraclass correlation coefficient >0.64), except for internal capsule (0.48) and M2 (0.55) regions. The areas under the receiver-operating curve ranged from 0.69-0.89 for the medical system, while for the smartphone ranged from 0.44-0.86. No statistical differences were observed between medical and smartphone reading systems for each region (all p > 0.05). DISCUSSION: If radiologists are better trained in the evaluation of the lesions in the insula, the internal capsule and the M2 regions, the total and the dichotomised Alberta Stroke Program Early CT Score will be more precise. Hence, ruling out contraindications to thrombolysis administration will be improved, allowing assessment of head computed tomography in a telestroke network using a smartphone to be a common practice.

Identifying gaps in the treatment of hepatitis C in patients co-infected with HIV in Edmonton, Alberta.

INTRODUCTION: With the availability of direct-acting antivirals, Hepatitis C (HCV) is now considered a treatable disease. Patients who are co-infected with human immunodeficiency virus (HIV) and HCV represent an ideal patient population to treat for HCV, as (1) patients are routinely taking medication for HIV, and therefore would be able to complete HCV drug regimens, and (2) HIV infection has been shown to increase HCV disease progression. OBJECTIVE: We sought to determine the occurrence of HCV co-infection among HIV patients in our provincial cohort, determine whether they received treatment for HCV, and identify currently viremic patients who can be linked to care. MATERIALS AND METHODS: HCV laboratory testing data (HCV antibody and HCV RNA) and HCV medication dispensation data was collected for all HIV positive patients. Current and previous HCV infection and treatment was assessed. Chart reviews were conducted for HCV viremic patients to assess their HIV care and social determinants. RESULTS: Of the 2417 HIV positive patients, 392 (16.2%) were identified as being co-infected with HCV. 198 (50.5%) of the HIV-HCV co-infected patients received HCV treatment and 232 (59.2%) were not viremic on the most recent HCV RNA test. 99 (69.2%) had a suppressed HIV infection suggesting they are active in their HIV care and good candidates for HCV treatment. CONCLUSION: Despite the availability of direct-acting antivirals, many patients who are co-infected with HIV and HCV are not being treated for HCV. Routine surveillance of HIV-HCV co-infected patients could improve HCV treatment rates in a high-risk population.

Concurrent validity of the Alberta Infant Motor Scale to detect delayed gross motor development in preterm infants: A comparative study with the Bayley III.

OBJECTIVE: To investigate the concurrent validity of AIMS in relation to the gross motor subtest of the Bayley Scale III/GM in preterm infants. METHODS: A total of 159 gross motor development assessments were performed with the AIMS and Bayley-III/GM. Linear regression was used to assess the correlation between AIMS and Bayley-III/GM scores. The intra-class correlation coefficient (ICC) and the Bland-Altman plot were used to analyze intra- and inter-rater reliability. RESULTS: There was a prevalence of delayed gross motor development of 20.8% according to the Bayley-III/GM, and 11.9% for the 5th percentile and 21.4% for the 10th percentile of AIMS. A good correlation of AIMS with Bayley-III/GM scores and intra- and inter-rater reliability was encountered in this study. CONCLUSION: AIMS proved very capable of detecting delayed gross motor development in preterm infants when compared with the Bayley-III/GM. The 10th percentile of AIMS provided the best combination of indicators, with greater specificity.

Desenvolvimento motor em RN prematuros / Motor development of premature newborns

A prematuridade e o extremo baixo peso estão associados a um baixo desenvolvimento cognitivo, além de atraso no desenvolvimento motor. Os fisioterapeutas são os primeiros avaliadores e provedores de cuidados na identificação e no tratamento dessas crianças e necessitam de uma avaliação sensível, para detectar alterações e reprodutível, além de conhecer prováveis fatores que se correlacionem com atraso no desenvolvimento neuropsicomotor (ADNPM) nesta população. O objetivo foi conhecer possíveis fatores presentes ao nascimento e durante o follow-up de crianças pré-termo que se correlacionem com o ADNPM. Estudo retrospectivo de análise de prontuários de crianças acompanhadas no follow-up, avaliadas pela AIMS e apresentavam registro completo do nascimento e período de internação. Foram selecionados 37 e 11 prontuários incluídos para análise. A média de idade das crianças avaliadas foi de 8,63 ± 2,11 meses, a idade gestacional média foi 30 ± 3,06 semanas e o peso ao nascimento de 1.331 ± 496,53 gramas. Houve uma correlação moderada e positiva entre a pontuação na AIMS e o perímetro cefálico (PC) ao nascimento (r=0,62 e p=0,04). O PC e o peso se encontravam abaixo e no percentil 5, respectivamente, no momento da avaliação em 70% das crianças. RNPT de muito baixo peso podem apresentar ADNPM, baixo desenvolvimento pondero-estatural e tempo prolongado de suporte ventilatório e internação na UTI. Quanto menor o PC ao nascimento e se este permanecer abaixo do percentil 5 após e sexto mês, provavelmente o ADNPM estará presente no primeiro ano de vida.

Clinical course of asymmetric motor performance and deformational plagiocephaly in very preterm infants.

OBJECTIVES: To describe the clinical courses of positional preference and deformational plagiocephaly up to 6 months corrected age (CA) in infants born at gestational age <30 weeks or birth weight <1000 g, and to explore predictive factors for the persistence of these phenomena. STUDY DESIGN: A total of 120 infants were examined 3 times each. The presence of deformational plagiocephaly and a score of 0-6 on an asymmetry performance scale served as outcome measures at 6 months CA. Predictive factors were determined using regression analysis. RESULTS: The prevalence of a positional preference of the head was 65.8% (79 of 120) at term-equivalent age (TEA) and 36.7% (44 of 120) at 3 months CA and that of deformational plagiocephaly was 30% (36 of 120) at TEA and 50% (60 of 120) at 3 months CA. At 6 months CA, 15.8% of the infants (19 of 120) scored ≥ 2 of a possible 6 on the asymmetry performance scale and 23.3% (28 of 120) had deformational plagiocephaly. Sleeping in the supine position was predictive of an asymmetric motor performance at 6 months CA. Chronic lung disease and/or slow gross motor maturation at 3 months CA predicted the persistence of deformational plagiocephaly. CONCLUSION: Infants born very preterm may develop deformational plagiocephaly. A positional preference of the head at TEA seems to be a normal aspect of these infants' motor repertoire, with limited ability to predict persistence of an asymmetric motor performance. The decreased prevalence of deformational plagiocephaly between 3 and 6 months CA indicates an optimistic course. Infants with a history of chronic lung disease and/or slow gross motor maturation merit timely intervention.

Differences in walking attainment ages between low-risk preterm and healthy full-term infants / Diferenças na idade de aquisição da marcha entre lactentes pré-termo de baixo risco e a termo saudáveis

OBJECTIVE: To compare gross motor development of preterm infants (PT) without cerebral palsy with healthy full-term (FT) infants, according to Alberta Infant Motor Scale (AIMS); to compare the age of walking between PT and FT; and whether the age of walking in PT is affected by neonatal variables. METHODS: Prospective study compared monthly 101 PT and 52 FT, from the first visit, until all AIMS items had been observed. Results: Mean scores were similarity in their progression, except from the eighth to tenth months. FT infants were faster in walking attainment than PT. Birth weight and length and duration of neonatal nursery stay were related to walking delay. CONCLUSION: Gross motor development between PT and FT were similar, except from the eighth to tenth months of age. PT walked later than FT infants and predictive variables were birth weight and length, and duration of neonatal intensive unit stay.

OBJETIVO: Comparar o desenvolvimento motor de lactentes pré-termo sem paralisia cerebral (PT) com lactentes normais nascidos a termo (T), de acordo com Escala Motora Infantil de Alberta (AIMS); comparar idade da marcha entre PT e T e se a idade da marcha em PT é passível de ser afetada. MÉTODOS: Estudo prospectivo com 101 PT e 52 T, seguidos mensalmente até que todos os itens da AIMS tivessem sido observados. Resultados: Os escores médios apresentaram semelhanças entre os grupos, com exceção do oitavo ao décimo meses. Os lactentes T iniciaram marcha antes dos PT. Peso, estatura ao nascimento e tempo de internação na unidade de terapia intensiva neonatal (UTIN) foram preditivos. CONCLUSÃO: O desenvolvimento motor entre PT e T foi semelhante, exceto entre o oitavo e o décimo meses de idade. PT andaram mais tardiamente e variáveis preditivas foram peso, estatura ao nascimento e o tempo de permanência na UTIN.

Validade concorrente e confiabilidade da Alberta Infant Motor Scale em lactentes nascidos prematuros / Concurrent validity and reliability of the Alberta Infant Motor Scale in premature infants

OBJETIVO: Verificar a validade concorrente e a confiabilidade interobservador da Alberta Infant Motor Scale (AIMS) em lactentes prematuros acompanhados no ambulatório de seguimento do Instituto Fernandes Figueira, Fundação Oswaldo Cruz (IFF/Fiocruz). MÉTODOS: Foram avaliados 88 lactentes nascidos prematuros no ambulatório de seguimento do IFF/Fiocruz entre fevereiro e dezembro de 2006. No estudo de validade concorrente, 46 lactentes com 6 (n = 26) ou 12 (n = 20) meses de idade corrigida foram avaliados pela AIMS e pela escala motora da Bayley Scales of Infant Development, 2ª edição, por dois observadores diferentes, utilizando-se o coeficiente de correlação de Pearson para análise dos resultados. No estudo de confiabilidade, 42 lactentes entre 0 e 18 meses foram avaliados pela AIMS por dois observadores diferentes, utilizando-se o intraclass correlation coefficient (ICC) para análise dos resultados. RESULTADOS: No estudo de validade concorrente, a correlação encontrada entre as duas escalas foi alta (r = 0,95) e estatisticamente significativa (p < 0,01) na população total de lactentes, alcançando valores mais altos aos 12 meses (r = 0,89) do que aos 6 meses (r = 0,74). A confiabilidade interobservador apresentou valores satisfatórios de ICC em todas as idades avaliadas, variando de 0,76 a 0,99. CONCLUSÃO: A AIMS é uma escala válida e confiável para ser utilizada na avaliação do desenvolvimento motor de lactentes de risco na população da rede pública de saúde brasileira.

OBJECTIVE: To verify the concurrent validity and interobserver reliability of the Alberta Infant Motor Scale (AIMS) in premature infants followed-up at the outpatient clinic of Instituto Fernandes Figueira, Fundação Oswaldo Cruz (IFF/Fiocruz), in Rio de Janeiro, Brazil. METHODS: A total of 88 premature infants were enrolled at the follow-up clinic at IFF/Fiocruz, between February and December of 2006. For the concurrent validity study, 46 infants were assessed at either 6 (n = 26) or 12 (n = 20) months' corrected age using the AIMS and the second edition of the Bayley Scales of Infant Development, by two different observers, and applying Pearson's correlation coefficient to analyze the results. For the reliability study, 42 infants between 0 and 18 months were assessed using the Alberta Infant Motor Scale, by two different observers and the results analyzed using the intraclass correlation coefficient. RESULTS: The concurrent validity study found a high level of correlation between the two scales (r = 0.95) and one that was statistically significant (p < 0.01) for the entire population of infants, with higher values at 12 months (r = 0.89) than at 6 months (r = 0.74). The interobserver reliability study found satisfactory intraclass correlation coefficients at all ages tested, varying from 0.76 to 0.99. CONCLUSIONS: The AIMS is a valid and reliable instrument for the evaluation of motor development in high-risk infants within the Brazilian public health system.
