\"Not Fit to Stay: Public Health Panics and South Asian Exclusion examines how and why South Asians were prevented from immigrating to British Columbia, Washington, Oregon, and California between 1900 and 1920. In the first decades of the twentieth century, all Asian immigrants to Canada and the United States faced opposition to their arrival and settlement. While racism and fear of labour competition were at the heart of this resistance, panic soon swept up and down the West Coast of North America over unsubstantiated public health concerns. Public leaders--including physicians, union leaders, civil servants, journalists, and politicians--latched on to these health concerns as the basis for the exclusion of the South Asians, who were said to suffer from medical conditions and diseases attributed to their race. Even though many officials knew the public health argument had no grounds, they promoted it to support their racist views and concerns about labour. Legislation to restrict the immigration of South Asians took effect in Canada in 1908 and in the United States in 1917. This book is an important study of how white North Americans saw first-wave South Asian immigrants as separate from, and inferior to, other groups in the evolving racial hierarchy on the West Coast of North America.\"-- Provided by publisher.

Reduced saturated fat (SFA) consumption is recommended to reduce coronary heart disease (CHD), but there is an absence of strong supporting evidence from randomized controlled trials (RCTs) of clinical CHD events and few guidelines focus on any specific replacement nutrient. Additionally, some public health groups recommend lowering or limiting polyunsaturated fat (PUFA) consumption, a major potential replacement for SFA. We systematically investigated and quantified the effects of increased PUFA consumption, as a replacement for SFA, on CHD endpoints in RCTs. RCTs were identified by systematic searches of multiple online databases through June 2009, grey literature sources, hand-searching related articles and citations, and direct contacts with experts to identify potentially unpublished trials. Studies were included if they randomized participants to increased PUFA for at least 1 year without major concomitant interventions, had an appropriate control group, and reported incidence of CHD (myocardial infarction and/or cardiac death). Inclusions/exclusions were adjudicated and data were extracted independently and in duplicate by two investigators and included population characteristics, control and intervention diets, follow-up duration, types of events, risk ratios, and SEs. Pooled effects were calculated using inverse-variance-weighted random effects meta-analysis. From 346 identified abstracts, eight trials met inclusion criteria, totaling 13,614 participants with 1,042 CHD events. Average weighted PUFA consumption was 14.9% energy (range 8.0%-20.7%) in intervention groups versus 5.0% energy (range 4.0%-6.4%) in controls. The overall pooled risk reduction was 19% (RR = 0.81, 95% confidence interval [CI] 0.70-0.95, p = 0.008), corresponding to 10% reduced CHD risk (RR = 0.90, 95% CI = 0.83-0.97) for each 5% energy of increased PUFA, without evidence for statistical heterogeneity (Q-statistic p = 0.13; I(2) = 37%). Meta-regression identified study duration as an independent determinant of risk reduction (p = 0.017), with studies of longer duration showing greater benefits. These findings provide evidence that consuming PUFA in place of SFA reduces CHD events in RCTs. This suggests that rather than trying to lower PUFA consumption, a shift toward greater population PUFA consumption in place of SFA would significantly reduce rates of CHD.

Purpose The purpose of this article is to revisit the role of augmentative and alternative communication (AAC) in poststroke aphasia rehabilitation. The authors' intent is to provide a viewpoint that expands the use of AAC in poststroke aphasia rehabilitation. Specifically, we seek to clarify the role of AAC in restorative and participation approaches to aphasia rehabilitation while also considering the role of AAC in a comprehensive treatment plan. The authors support their viewpoint with citations from both the historic and contemporary literature on aphasia rehabilitation. Conclusions A thought-provoking viewpoint on the role of AAC in poststroke aphasia rehabilitation is proposed. More specifically, the versatility of AAC strategies is reviewed, with an emphasis on how AAC can be used to empower people with aphasia to fully participate and engage in life activities with increased independence. Moreover, we argue that AAC can be viewed as a dual-purpose tool that can simultaneously serve to drive intersystemic reorganization resulting in some improved language performance-and perhaps restoration of language function-while offering a communication alternative during inevitable anomic events.

We evaluated the performance of the MinION DNA sequencer in-flight on the International Space Station (ISS), and benchmarked its performance off-Earth against the MinION, Illumina MiSeq, and PacBio RS II sequencing platforms in terrestrial laboratories. Samples contained equimolar mixtures of genomic DNA from lambda bacteriophage, Escherichia coli (strain K12, MG1655) and Mus musculus (female BALB/c mouse). Nine sequencing runs were performed aboard the ISS over a 6-month period, yielding a total of 276,882 reads with no apparent decrease in performance over time. From sequence data collected aboard the ISS, we constructed directed assemblies of the ~4.6 Mb E. coli genome, ~48.5 kb lambda genome, and a representative M. musculus sequence (the ~16.3 kb mitochondrial genome), at 100%, 100%, and 96.7% consensus pairwise identity, respectively; de novo assembly of the E. coli genome from raw reads yielded a single contig comprising 99.9% of the genome at 98.6% consensus pairwise identity. Simulated real-time analyses of in-flight sequence data using an automated bioinformatic pipeline and laptop-based genomic assembly demonstrated the feasibility of sequencing analysis and microbial identification aboard the ISS. These findings illustrate the potential for sequencing applications including disease diagnosis, environmental monitoring, and elucidating the molecular basis for how organisms respond to spaceflight.

As we explore beyond Earth, astronauts may be at risk for harmful DNA damage caused by ionizing radiation. Double-strand breaks are a type of DNA damage that can be repaired by two major cellular pathways: non-homologous end joining, during which insertions or deletions may be added at the break site, and homologous recombination, in which the DNA sequence often remains unchanged. Previous work suggests that space conditions may impact the choice of DNA repair pathway, potentially compounding the risks of increased radiation exposure during space travel. However, our understanding of this problem has been limited by technical and safety concerns, which have prevented integral study of the DNA repair process in space. The CRISPR/Cas9 gene editing system offers a model for the safe and targeted generation of double-strand breaks in eukaryotes. Here we describe a CRISPR-based assay for DNA break induction and assessment of double-strand break repair pathway choice entirely in space. As necessary steps in this process, we describe the first successful genetic transformation and CRISPR/Cas9 genome editing in space. These milestones represent a significant expansion of the molecular biology toolkit onboard the International Space Station.

ObjectivesA consensus study to establish a Core Outcome Set for dysarthria after stroke identified four key outcome domains that should be measured in research and clinical practice: (1) intelligibility of speech, (2) ability to participate in conversations, (3) living well with dysarthria and (4) communication partners skills and knowledge (where relevant). This review aimed to systematically identify corresponding measurement instruments and to examine their clinical utility and psychometric properties.DesignSystematic review conducted in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.Data sourcesCINAHL, EMBASE, MEDLINE, PsycInfo and Cochrane Stroke Group Trials Register, CENTRAL, Linguistics and Language Behavioral Abstracts (LLBA). Major trials registers: WHO ICTRP, ISRCTN registry and ClinicalTrials.gov searched March 2024.Eligibility criteria for selecting studiesWe included trials that developed or used measurement instruments for poststroke dysarthria. We identified studies that could be included in an update of the Cochrane systematic review of interventions for non-progressive dysarthria to identify what measurement instruments were used in therapy trials for poststroke dysarthria.Data extraction and synthesisRecords were screened independently by three authors. Psychometric data were extracted, by two authors, from included studies and methodological quality was evaluated using Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) and Core Outcome Measures in Effectiveness Trials (COMET) guidance. Assessment of clinical utility followed Outcome Measures in Rheumatology (OMERACT) guidance.ResultsFollowing screening, 19 publications reporting 12 measurement instruments were identified. According to COSMIN standards, all 19 publications were rated as having low, very low or unknown quality of evidence. Three measurement instruments were identified as having the most relevant clinical utility to the population, the highest quality of evidence and had the potential to measure some specific aspects from three of the four agreed domains, intelligibility, conversations and living well with dysarthria from the patient and clinician perspective. These were the Frenchay Dysarthria Assessment II, the Communication Outcomes After Stroke Scale and the Therapy Outcome Measures for Dysarthria.ConclusionsThis review provides a comprehensive overview and appraisal of dysarthria measurement instruments to align with a Core Outcome Set. We only included English language-based measurement instruments. Many dysarthria measurement instruments were developed for non-stroke populations, including progressive dysarthria, with limited psychometric data for stroke. Measurement instruments with uncertain quality of evidence can still be considered for inclusion with a Core Outcome Set and three have been suggested. There is a need for further psychometric testing of these and the development of new measurement instruments to cover all aspects of intelligibility, conversations, living well with dysarthria and communication partner skills.PROSPERO registration numberCRD42022302998.

ABSTRACT Background People with aphasia (PWA, impaired language/communication) are often excluded from research that concerns them due to a lack of methodological adaptations to support communication. This paper describes adaptations to support their involvement in experience‐based codesign (EBCD). Aims To describe the involvement of PWA in EBCD and critically evaluate adaptations required to support involvement. Methods Mixed methods process evaluation and reflexive critical appraisal with PWA, significant others (SO), and speech pathologists (SP). Using surveys, stakeholders (n = 127) and a consumer advisory group (CAG; n = 6) provided feedback on involvement in five stages of the research: (1) online interviews and focus groups; (2) online surveys; (3) consensus meetings; (4) codesign workshops; and (5) the CAG. Critical reflections (lead researcher) informed the analysis. Descriptive statistics and inductive content analysis were used. Results Most PWA (79%) liked sharing their experiences online, and contributed as much as desired in group meetings (64%). A modified touchpoint film approach (use of voice actors, still images, and subtitles) supported reflexive discussions and collaborative understanding. All PWA and SO, and most SPs (78%) thought the touchpoint film helped them to understand experiences of care and areas for change. Long‐term engagement in the project was perceived to help build relationships, reduce hierarchical power differentials and support equal sharing of ideas. Conclusions Meaningful involvement of PWA was supported through long‐term engagement, a modified touchpoint film approach, and hybrid methods of data collection. EBCD is a suitable approach for exploring experiences of care, identifying leading priorities, and co‐designing areas for change with PWA. Patient or Public Contribution This evaluation is informed by the reflections of the research team. This team included the consumer advisory group (public involvement team members) comprising PWA (n = 3), SOs (n = 2) and a Cultural Capability Officer. Research team members (LNA, DAC, VJP, and SJW) designed the study (including research questions, data analysis processes and assessment measures). Public involvement guided study procedures and recruitment (e.g., methods for engaging with people with lived experience of aphasia), and the interpretation and dissemination of results (e.g., co‐authors on papers). A Cultural Capability Officer advised on culturally safe practices for Aboriginal and Torres Strait Islander participants. Aboriginal and Torres Strait Islander Peoples, are the First Nations people of Australia. Cultural Capability Officer support refers to the support provided to ensure behaviours, systems and processes are conducted in a way that is culturally respectful. Research is reported in line with the GRIPP‐2 guidelines for reporting patient and public involvement.

Introduction Breast screening is an effective way to improve the early detection of breast cancer and reduce mortality. Unfortunately, low uptake of screening is often reported. This study aimed to explore the support needs of women residing in Newport West, Wales, to participate in breast screening. Methods Group Concept Mapping, a structured participatory consensus approach, was used as the method. Participants completed three activities either online or offline: brainstorming to generate statements, sorting statements into themed categories; rating statements for perceived importance and accessibility (easy to get). Results Thirty‐seven participants from seven ethnic groups took part. Sixty‐three statements (items of support) were generated and sorted into seven conceptually similar clusters (themes) (Trusting that I will be respected; Reassurance about my experience; Accessibility and convenience; Practical support; Addressing cultural diversity; Information tailored to individual needs; Raising awareness and understanding of breast screening). The ‘Trusting that I will be respected’ cluster was rated most important, while the ‘Practical support’ cluster was rated least accessible. Some disparity between responses was found based on ethnicity, language, disability and previous attendance of breast screening. Conclusions Women require a range of support to participate in breast screening. The results highlight the importance of ensuring women feel and are respected, instilling trust in the staff performing the screening, offering reassurance about positive experiences of breast screening and providing practical support, especially individualized/targeted support for people who do not speak and/or read English and those with a disability. Patient or Public Contribution The public contributed to the development of the information sheet, consent form, recruitment and data collection method.

The aim of this study was to assess the association between anxiety and depression with physical and sensory functional difficulties, among adults living in five low and middle-income countries (LMICs). A secondary data analysis was undertaken using population-based disability survey data from five LMICs, including two national surveys (Guatemala, Maldives) and 3 regional/district surveys (Nepal, India, Cameroon). 19,337 participants were sampled in total (range 1,617-7,604 in individual studies). Anxiety, depression, and physical and sensory functional difficulties were assessed using the Washington Group Extended Question Set on Functioning. Age-sex adjusted logistic regression analyses were undertaken to assess the association of anxiety and depression with hearing, visual or mobility functional difficulties. People with physical and sensory functional difficulties are more likely to report experiencing depression and anxiety. This evidence supports the need for ensuring a good awareness of mental health among those working with individuals with physical and sensory functional difficulties in LMICs. This implies that these practitioners must have the skills to identify anxiety and depression. Furthermore, mental health services must be available and accessible to patients with these conditions, which will likely require further programmatic scale-up in these LMIC settings.
