    Abstract Converging behavioral and neural evidence have suggested that visual stimuli could be attached to existing visual working memory sequentially in time. However, whether individual differences in sequential visual working memory paradigm are similar to those measured by the classical simultaneous change detection paradigm remain unknown. Here, we first show that sequentially presented visual stimuli exhibit similar working memory capacity bottlenecks as previous research using simultaneously presented items. We further reveal that within the same subject, the accuracy and capacity estimates using sequential and simultaneous paradigm were comparable across four different set sizes. Also, we discover that the individual differences measured by the sequential paradigm were highly correlated to those by the simultaneous paradigm within the same subject across all four set sizes of interest. Finally, we find that in a larger sample of subjects (n = 200), the variance and higher-order statistics were similar for sequential and simultaneous paradigms with set size of 6. Collectively, these findings indicate that individual differences measured by the sequential presentation of visual items rely on the similar working memory resources as those by the simultaneous form of presentation.

    Abstract The change detection paradigm has been a widely used approach for measuring capacity in visual working memory (WM). In this task, subjects see an array of visual items, followed by a short blank delay and a single test item. Their task is to indicate whether that test item changed relative to the item in the sample array. This task provides reliable measurements of WM capacity that exhibit robust correlations with many outcome variables of interest. Here, we offer a new variant of this task that we call "change localization." This task is closely modeled after the change detection task described above, except that the test array contains the same number of items as the sample array, and one item has always changed in each trial. The subject's task is to select the changed item in the test array. Using both color and shape stimuli, scores in the change localization task were highly correlated with those in the change detection task, suggesting that change localization taps into the same variance in WM ability. Moreover, the change localization task was far more reliable than change detection, such that only half the number of trials were required to achieve robust reliability. To further validate the approach, we replicated known effects from the literature, demonstrating that they could be detected with far fewer trials than with change detection. Thus, change localization provides a highly reliable and sensitive approach for measuring visual working memory capacity.

    Abstract Background: Population-level administrative data provides a cost-effective means of monitoring health outcomes and service needs of clinical populations. This study aimed to present a method for case identification of non-traumatic brain injury in population-level data and to examine the association with sociodemographic factors.
    Methods: An estimated resident population of youth aged 0-24 years was constructed using population-level datasets within the New Zealand Integrated Data Infrastructure. A clinical consensus committee reviewed the International Classification of Diseases Ninth and Tenth Editions codes and Read codes for inclusion in a case definition. Cases were those with at least one non-traumatic brain injury code present in the five years up until 30 June 2018 in one of four databases in the Integrated Data Infrastructure. Rates of non-traumatic brain injury were examined, both including and excluding birth injury codes and across age, sex, ethnicity, and socioeconomic deprivation groups.
    Results: Of the 1 579 089 youth aged 0-24 years on 30 June 2018, 8154 (0.52%) were identified as having one of the brain injury codes in the five-years to 30 June 2018. Rates of non-traumatic brain injury were higher in males, children aged 0-4 years, Māori and Pacific young people, and youth living with high levels of social deprivation.
    Conclusion: This study presents a comprehensive method for case identification of non-traumatic brain injury using national population-level administrative data.

    Abstract Background: COVID-19-related pleural effusions are frequently described during the ongoing pandemic.
    Objectives: We described the incidence, characteristics, and outcomes of COVID-19-related pleural effusions based on the current evidence available in the literature.
    Methods: We searched MEDLINE, Pubmed, and Google Scholar databases using keywords of "coronavirus disease 2019 (COVID-19)," "severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)," "pleural effusion," "pleural fluid," and "pleura" from January 1st, 2020 to January 31st, 2021.
    Results: The incidence of pleural effusions was low at 7.3% among the 47 observational studies. Pleural effusions were commonly observed in critically ill patients and had Multisystem Inflammatory Syndrome (MIS). COVID-19-related pleural effusions were identified 5-7 days and 11 days, after hospital admission and onset of COVD-19 symptoms. The characteristic findings of pleural fluid were exudative, lymphocytic or neutrophilic-predominant pleural fluid with markedly elevated lactate dehydrogenase (LDH) levels and pleural fluid to serum LDH ratio.
    Conclusion: A well-designed study is required to assess the significance of COVID-19-related pleural effusions during this current pandemic.
