Progress in computer-assisted Alberta stroke program early computer tomography score of acute ischemic stroke based on different modal images / 生物医学工程学杂志

Clinically, non-contrastive computed tomography (NCCT) is used to quickly diagnose the type and area of ​​stroke, and the Alberta stroke program early computer tomography score (ASPECTS) is used to guide the next treatment. However, in the early stage of acute ischemic stroke (AIS), it's difficult to distinguish the mild cerebral infarction on NCCT with the naked eye, and there is no obvious boundary between brain regions, which makes clinical ASPECTS difficult to conduct. The method based on machine learning and deep learning can help physicians quickly and accurately identify cerebral infarction areas, segment brain areas, and operate ASPECTS quantitative scoring, which is of great significance for improving the inconsistency in clinical ASPECTS. This article describes current challenges in the field of AIS ASPECTS, and then summarizes the application of computer-aided technology in ASPECTS from two aspects including machine learning and deep learning. Finally, this article summarizes and prospects the research direction of AIS-assisted assessment, and proposes that the computer-aided system based on multi-modal images is of great value to improve the comprehensiveness and accuracy of AIS assessment, which has the potential to open up a new research field for AIS-assisted assessment.

Correlation between acute ischemic stroke onset with Alberta stroke program early CT score

Background: Alberta Stroke Program Early CT Score (ASPECTS) is a valid method for assessing early ischemic changes in the middle cerebral artery from a CT scan of patient with acute ischemic stroke. One of the factors that influence ASPECTS is stroke onset time, where a very subtle level of hypodensity in early onset can provide poor reliability on ASPECTS assessments. Aim of the study was to determine the relationship between the onset of acute ischemic stroke and ASPECTS.Methods: This study used a cross-sectional design with Chi-Square method in patients with acute ischemic stroke and anterior circulation stroke treated in The Stroke Corner and Integrated Ward of Haji Adam Malik General Hospital during the months of February - May 2019. All patients were evaluated for ASPECTS and stroke onset at admission. Stroke onset was divided into 3 parts: Under 24 hours, 24 - <48 hours and 48-72 hours. ASPECTS value was assessed by 2 observers. Authors categorized the ASPECT value into 2 groups: Low (≤7) and High (˃7).Results: Among 36 patients with Acute Ischemic Stroke, mean age was 55.7±13.9 years old, which male and female shares equal number by 18 persons (50%). Mean ASPECTS score was 7.2±2.0. This research found 5 patients (13.9%) with less than 24 hours onset and low ASPECTS score, 3 patients (8.3%) with 24 - <48 hours onset and low ASPECTS score, 7 patients (19.4%) with 24 - <48 hours onset and high ASPECTS score, 8 patients (22.2%) with 48-72 hours onset and low ASPECTS score, and 2 patients (5.6%) with 48-72 hours of onset and high ASPECTS score. Valuation of ASPECTS from both observers was considered as excellent (statistic K value = 0.9).Conclusions: ASPECTS has a significant relationship with stroke onset (p=0.029) and the initial ischemic change will be seen more clearly with increasing stroke onset time.

Perceptions About Alcohol Harm and Alcohol-control Strategies Among People With High Risk of Alcohol Consumption in Alberta, Canada and Queensland, Australia / 예방의학회지

OBJECTIVES: To explore alcohol perceptions and their association hazardous alcohol use in the populations of Alberta, Canada and Queensland, Australia. METHODS: Data from 2500 participants of the 2013 Alberta Survey and the 2013 Queensland Social Survey was analyzed. Regression analyses were used to explore the association between alcohol perceptions and its association with hazardous alcohol use. RESULTS: Greater hazardous alcohol use was found in Queenslanders than Albertans (p < 0.001). Overall, people with hazardous alcohol were less likely to believe that alcohol use contributes to health problems (odds ratio [OR], 0.46; 95% confidence interval [CI], 0.27 to 0.78; p < 0.01) and to a higher risk of injuries (OR, 0.54; 95% CI, 0.33 to 0.90; p < 0.05). Albertans with hazardous alcohol use were less likely to believe that alcohol contributes to health problems (OR, 0.48; 95% CI, 0.26 to 0.92; p < 0.05) and were also less likely to choose a highly effective strategy as the best way for the government to reduce alcohol problems (OR, 0.63; 95% CI, 0.43 to 0.91; p=0.01). Queenslanders with hazardous alcohol use were less likely to believe that alcohol was a major contributor to injury (OR, 0.39; 95% CI, 0.20 to 0.77; p < 0.01). CONCLUSIONS: Our results suggest that people with hazardous alcohol use tend to underestimate the negative effect of alcohol consumption on health and its contribution to injuries. In addition, Albertans with hazardous alcohol use were less in favor of strategies considered highly effective to reduce alcohol harm, probably because they perceive them as a potential threat to their own alcohol consumption. These findings represent valuable sources of information for local health authorities and policymakers when designing suitable strategies to target alcohol-related problems.

A predictive value of post-thrombolysis hemorrhagic transformation in acute cerebral infarction predicted by Alberta stroke program early CT score, hemorrhage after thrombolysis score and related factors / 中国中西医结合急救杂志

Objective To observe the predictive value of Alberta stroke program early CT score (ASPECTS) and hemorrhage after thrombolysis score (HAT score) for the hemorrhagic transformation (HT) of acute cerebral infarction (ACI) patients after thrombolysis with Alteplase.Methods One hundred and twenty-one patients with ACI admitted to the Department of Neurology of Tianjin Jinghai District Hospital from January 2015to March 2017 were enrolled, they were all treated by using Alteplase 0.6 mg/kg for thrombolysis, maximum dose being 90 mg, and 1/10 of the total dose was intravenously injected in 1 minute, and then the residual part dissolved in 100 mL normal saline was intravenously dripped continuously for 1 hour. The ASPECTS and HAT score were carried out before the start of thrombolysis, and then the HT incidence situations in patients with different ASPECTSs and HAT scores were compared, and logistic regression analysis was used to analyze the risk factors of HT after thrombolysis in patients with ACI; then the receiver operating characteristic (ROC) curve was drawn, and the clinical value of HAT score and ASPECTS in diagnosing HT occurrence was analyzed.Results In cases with ACI, it was discovered that the higher the ASPECTS, the lower the incidence of HT, indicating that the incidences of HT in patients with ASPECTSs 0-4, 5-7, 8-10 were 57.1% (4/7), 26.7% (8/30), 14.3% (12/84) respectively; Similarly, in such cases, the higher the HAT scores, the higher the incidence of HT, showing that the incidences of HT of patients with HAT scores 0, 1, 2, ≥ 3 were 7.1% (4/56), 21.0% (8/38), 33.3% (7/21), 83.3% (5/6) respectively. The single factor analysis showed that the risk factors influencing the HT incidence included the systolic blood pressure on admission, anti-platelet medicine taken in the past history, the sign of high density of middle cerebral artery shown in head CT film on admission, the time of interval between the onset of the disease and the beginning of thrombolysis, HAT store and ASPECTS [odds ratio (OR) values were 0.972, 0.279, 0.992, 0.311, 2.628, 2.625, respectively, 95% confidence intervals (95%CI) were 0.9352-1.012, 0.093-0.836, 0.983-1.000, 0.105-0.916, 1.362-5.071, 1.522-4.525,P values were 0.034, 0.023, 0.042, 0.034, 0.003, 0.045 respectively]; the multifactorial logistic regression analysis showed that the independent risk factors influencing HT incidence were as follows: the systolic blood pressure on admission, anti-platelet medicines taken in the past history, the sign of high density of the middle cerebral artery shown in the head CT film on admission, the time of interval between the onset of the disease and the beginning of thrombolysis, HAT score and ASPECTS (OR values were 1.766, 1.012, 1.574, 1.030, 2.155, 2.431, 95%CI were 1.233-2.103, 1.009-1.204, 1.186-2.091, 1.009-1.053, 1.237-4.907, 1.213-5.815,P values were 0.023, 0.004, 0.002, 0.005, 0.007, 0.047); HAT score and ASPECTS could predict the risk of HT incidence after venous thrombolytic therapy, sensitivity, specificity, area under ROC curve (AUC), 95%CI in ASPECTS were higher than thoes of HAT score (94.4% vs. 94.0%, 61.4 vs. 41.0%, 0.77 vs. 0.70, 0.710-0.830 vs. 0.650-0.800).Conclusions It is shown in this study that the higher the ASPECTS, the lower the incidence of HT, and the higher the HAT score, the higher the incidence of HT; both HAT score and ASPECTS can predict the risk of HT incidence after venous thrombolytic therapy, and the predictive value of ASPECTS system is higher than that of HAT score.

Hazardous Alcohol Use in 2 Countries: A Comparison Between Alberta, Canada and Queensland, Australia / 예방의학회지

OBJECTIVES: This article aimed to compare alcohol consumption between the populations of Queensland in Australia and Alberta in Canada. Furthermore, the associations between greater alcohol consumption and socio-demographic characteristics were explored in each population. METHODS: Data from 2500 participants of the 2013 Alberta Survey and the 2013 Queensland Social Survey were analyzed. Regression analyses were used to explore the associations between alcohol risk and socio-demographic characteristics. RESULTS: A higher rate of hazardous alcohol use was found in Queenslanders than in Albertans. In both Albertans and Queenslanders, hazardous alcohol use was associated with being between 18 and 24 years of age. Higher income, having no religion, living alone, and being born in Canada were also associated with alcohol risk in Albertans; while in Queenslanders, hazardous alcohol use was also associated with common-law marital status. In addition, hazardous alcohol use was lower among respondents with a non-Catholic or Protestant religious affiliation. CONCLUSIONS: Younger age was associated with greater hazardous alcohol use in both populations. In addition, different socio-demographic factors were associated with hazardous alcohol use in each of the populations studied. Our results allowed us to identify the socio-demographic profiles associated with hazardous alcohol use in Alberta and Queensland. These profiles constitute valuable sources of information for local health authorities and policymakers when designing suitable preventive strategies targeting hazardous alcohol use. Overall, the present study highlights the importance of analyzing the socio-demographic factors associated with alcohol consumption in population-specific contexts.

Analysis of influencing factors of the prognosis of intravenous thrombolysis combined with endovascular interventional therapy in patients with acute moderate to severe cerebral infarction / 中国脑血管病杂志

Objective To study the prognostic influencing factors for intravenous thrombolysis combined with endovascular interventional therapy in patients with acute moderate to severe cerebral infarction. Methods From September 2013 to December 2015,the clinical data of 179 patients with moderate to severe acute cerebral infarction treated with intravenous thrombolysis combined with endovascular interventional therapy at the Cerebrovascular Disease Center,Shanghai Changhai Hospital were analyzed retrospectively. They were all treated with intravenous thrombolysis combined at least 1 endovascular interventional therapy (intra-arterial thrombolysis,mechanical thrombectomy or stenting)within 4. 5 h after onset. The patients with mRS ≤2 were divided into a good prognosis group (n = 71),those with 3≤mRS≤ 6 were divided into a poor prognosis group (n = 108)according to the modified Rankin Scale (mRS) scores after 3 months of treatment. The clinical data of both groups were analyzed,including age,sex,previous history,the National Institutes of Health Stroke Scale (NIHSS)score and Alberta stroke program early CT score (ASPECTS)immediately before and after treatment. The influencing factors of prognosis were further analyzed with multivariate Logistic regression analysis. Results The rate of good prognosis was 39. 7%(71 / 179). There were significant differences in age,history of transient ischemic attack at 1 week before the disease onset,the NIHSS score,and ASPECTS score before thrombolysis (62 ± 14 years vs. 71 ± 11 years,8. 4% (6 / 71)vs. 1. 9% (2 / 108),16 ± 6 vs. 19 ± 6,and 9. 5 ± 1. 0 vs. 8. 5 ± 1. 9,respectively;all P 0. 05). There were significant differences in the NIHSS score immediately after treatment,24 h intracranial hemorrhage transformation,and intraparenchymal hemorrhage between the good prognosis group and the poor prognosis group (10 ± 3 vs. 15 ± 7,7. 0%[5 / 71]vs. 28. 7%[31 / 108],and 0 vs. 12. 0%[13 / 108];all P < 0. 01). Multivariate Logistic regression analysis showed that the age (OR,1. 047,95% CI 1. 014 -1. 081;P = 0. 005),NIHSS score immediately after treatment (OR,1. 121,95% CI 1. 050 -1. 196;P =0. 001)were the prognostic risk factors for intravenous thrombolysis combined with endovascular interven-tional therapy for moderate to severe cerebral infarction. The ASPECTS on admission (OR,0. 382,95% CI 0. 233 -0. 627;P < 0. 01)was the protective factor. Conclusions The age and the NIHSS score immediately after treatment are the prognostic risk factors for intravenous thrombolysis combined with endovascular inter-ventional therapy for moderate to severe cerebral infarction. With the increase of age and the NIHSS score after treatment,the prognosis of patients is even worse. With the increase of ASPECTS score at admission,the prognosis is better.

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.

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.
