Sequential congruency effects in monolingual and bilingual adults: A failure to replicate Grundy et al. (2017)

Previous research suggests bilingual adults show smaller sequential congruency effects than monolingual adults. Here we re-examined these findings by administering an Eriksen flanker task to monolingual and bilingual adults. The task produced robust conventional and sequential congruency effects. Neither effect differed for monolingual and bilingual adults. Results are discussed in terms of current debates concerning differences in cognitive control between monolingual and bilingual adults

The Bilingual Advantage in Children’s Executive Functioning Is Not Related to Language Status: A Meta-Analytic Review

There is considerable debate about whether bilingual children have an advantage in executive functioning relative to monolingual children. In the current meta-analysis, we addressed this debate by comprehensively reviewing the available evidence. We synthesized data from published studies and unpublished data sets, which equated to 1,194 effect sizes from 10,937 bilingual and 12,477 monolingual participants between the ages of 3 and 17 years. Bilingual language status had a small overall effect on children’s executive functioning (g =.08, 95% confidence interval = [.01,.14]). However, the effect of language status on children’s executive functioning was indistinguishable from zero (g = −.04) after we adjusted for publication bias. Further, no significant effects were apparent within the executive-attention domain, in which the effects of language status have been hypothesized to be most pronounced (g =.06, 95% confidence interval = [−.02,.14]). Taken together, available evidence suggests that the bilingual advantage in children’s executive functioning is small, variable, and potentially not attributable to the effect of language status

Estimating loss in capability wellbeing in the first year of the COVID-19 pandemic:a cross-sectional study of the general adult population in the UK, Australia and the Netherlands

Objectives To estimate capability wellbeing lost from the general adult populations in the UK, Australia and the Netherlands in the first year of the COVID-19 pandemic and the associated social restrictions, including lockdowns. Design Cross-sectional with recalled timepoints. Setting Online panels in the UK, Australia and the Netherlands conducted in February 2021 (data collected 26 January-2 March 2021). Participants Representative general adult (>= 18 years old) population samples in the UK (n = 1,017), Australia (n = 1,011) and the Netherlands (n = 1,017) Main outcome measure Participants completed the ICECAP-A capability wellbeing measure in February 2021, and for two recalled timepoints during the initial lockdowns in April 2020 and in February 2020 (prior to COVID-19 restrictions in all three countries). ICECAP-A scores on a 0-1 no capability-full capability scale were calculated for each timepoint. Societal willingness to pay estimates for a year of full capability (YFC) was used to place a monetary value associated with change in capability per person and per country. Paired t tests were used to compare changes in ICECAP-A and YFC from pre- to post-COVID-19-related restrictions in each country. Results Mean (standard deviation) loss of capability wellbeing during the initial lockdown was 0.100 (0.17) in the UK, 0.074 (0.17) in Australia and 0.049 (0.12) in the Netherlands. In February 2021, losses compared to pre-lockdown were 0.043 (0.14) in the UK, 0.022 (0.13) in Australia and 0.006 (0.11) in the Netherlands. In monetary terms, these losses were equivalent to 14.8 pound billion, AUD$8.6 billion and euro2.1 billion lost per month in April 2020 and 6.4 pound billion, A$2.6 billion and euro260 million per month in February 2021 for the UK, Australia and the Netherlands, respectively. Conclusions There were substantial losses in capability wellbeing in the first year of the COVID-19 pandemic. Future research is required to understand the specific impact of particular COVID-19 restrictions on people's capabilities

"Are we working (too) comfortably?”:Understanding the nature of and factors associated with sedentary behaviour when working in the home environment

Home working has increased due to COVID-19, but little is known about how this change has impacted the health risk behaviour of elevated sedentary time. The aim of this cross-sectional exploratory study was to assess occupational sitting behaviour when working at home, and use the Capability Opportunity Motivation-Behaviour (COM-B) model to identify influences on this behaviour. University staff (n = 267; 69% female; 92% white) who were predominantly working from home completed a questionnaire to assess sitting time, sitting breaks, demographic and occupational characteristics, and a 7-item COM-B questionnaire and open-ended questions to assess influences on time spent sitting whilst working from home. Data were analysed descriptively, a repeated measures ANOVA was used to determine differences in the COM-B items, and binary logistic regression was used to examine predictors of sitting time. Staff spent on average 89.5% (SD = 17.1) of their time sitting whilst working at home, and took an average of 1.36 (1.38) sitting breaks per hour. There were significant and meaningful differences in the influence of the COM factors on ability and willingness to reduce sitting behaviour (p < .0001; η(p)(2) = .38), and the open-ended responses added further context. The included variables accounted for 20.7% of variance in sitting behaviour, with age, sitting breaks, motivation-automatic, and opportunity-physical contributing significantly. Working from home leads to elevated levels of sitting, and the COM-B provides a useful model to identify key influences on ability and willingness to reduce sitting. Strategies incorporating regular breaks, habit formation/reversal, and restructuring the physical environment may be beneficial

Rx for Hunger: Affordable Housing

This report by Children's HealthWatch and the Medical-Legal Partnership | Boston finds that housing plays a significant role in protecting young children from food insecurity and the health risks of being seriously underweight. This report confirms that increased support for subsidized housing must be part of the strategy for ending childhood hunger

Bringing Children in from the Cold: Solutions for Boston's Hidden Homeless

This report describes a population of "hidden homeless" families and new research showing that children in these families are more likely to be hungry and in poor health. Unrecorded by any homeless census, these families move frequently, often into overcrowded apartments, or double up with another family never knowing how long they can stay. The report estimates that there are over 14,800 hidden homeless families in Boston and that this number is likely to grow as the economy declines

Microlaser-based contractility sensing in single cardiomyocytes and whole hearts

Microscopic whispering gallery mode lasers detect minute changes in cellular refractive index inside individual cardiac cells and in live zebrafish. We show that these signals encode cardiac contractility that can be used for intravital sensing.Postprin

Acanthamoeba induces cell-cycle arrest in host cells

Acanthamoeba can cause fatal granulomatous amoebic encephalitis (GAE) and eye keratitis. However, the pathogenesis and pathophysiology of these emerging diseases remain unclear. In this study, the effects of Acanthamoeba on the host cell cycle using human brain microvascular endothelial cells (HBMEC) and human corneal epithelial cells (HCEC) were determined. Two isolates of Acanthamoeba belonging to the T1 genotype (GAE isolate) and T4 genotype (keratitis isolate) were used, which showed severe cytotoxicity on HBMEC and HCEC, respectively. No tissue specificity was observed in their ability to exhibit binding to the host cells. To determine the effects of Acanthamoeba on the host cell cycle, a cell-cycle-specific gene array was used. This screened for 96 genes specific for host cell-cycle regulation. It was observed that Acanthamoeba inhibited expression of genes encoding cyclins F and G1 and cyclin-dependent kinase 6, which are proteins important for cell-cycle progression. Moreover, upregulation was observed of the expression of genes such as GADD45A and p130 Rb, associated with cell-cycle arrest, indicating cell-cycle inhibition. Next, the effect of Acanthamoeba on retinoblastoma protein (pRb) phosphorylation was determined. pRb is a potent inhibitor of G1-to-S cell-cycle progression; however, its function is inhibited upon phosphorylation, allowing progression into S phase. Western blotting revealed that Acanthamoeba abolished pRb phosphorylation leading to cell-cycle arrest at the G1-to-S transition. Taken together, these studies demonstrated for the first time that Acanthamoeba inhibits the host cell cycle at the transcriptional level, as well as by modulating pRb phosphorylation using host cell-signalling mechanisms. A complete understanding of Acanthamoeba–host cell interactions may help in developing novel strategies to treat Acanthamoeba infections

Longitudinal clusters of pain and stiffness in polymyalgia rheumatica: 2-year results from the PMR Cohort study

Objectives. To investigate potential subgroups of primary care diagnosed patients with polymyalgia rheumatica (PMR) based on self-reported pain and stiffness severity over time.Methods. 652 people with an incident PMR diagnosis were recruited from English general practices and completed a baseline postal questionnaire. They were followed-up with a further six questionnaires over a two-year period. 446 people completed 2-year follow-up. Pain and stiffness were reported on 0-10 numerical rating scales. Latent class growth analysis was used to estimate the joint trajectories of pain and stiffness overtime. A combination ofstatistical and clinical considerations was used to choose the number of clusters. Characteristics of the classes were described. Results. Five clusters were identified. One cluster represented the profile of ‘classical’ PMR symptoms and one represented sustained symptoms that may not be PMR. The other three clusters displayed a partial recovery, a recovery followed by worsening and a slow, but sustained recovery. Those displaying classical PMR symptoms were in better overall health at diagnosis than the other groups.Conclusions. PMR is a heterogeneous condition, with a number of phenotypes. The spectrum of presentation, as well as varying responses to treatment, may be related to underlying health status at diagnosis. Future research should seek to stratify patients at diagnosis to identify those likely to have a poor recovery and in need of an alternative treatment pathway. Clinicians should be aware of the different experiences of patients and monitor symptoms closely, even where there is initial improvement
