An integrated toolkit for human microglia functional genomics.

BACKGROUND: Microglia, the brain's resident immune cells, play vital roles in brain development, and disorders like Alzheimer's disease (AD). Human iPSC-derived microglia (iMG) provide a promising model to study these processes. However, existing iMG generation protocols face challenges, such as prolonged differentiation time, lack of detailed characterization, and limited gene function investigation via CRISPR-Cas9. METHODS: Our integrated toolkit for in-vitro microglia functional genomics optimizes iPSC differentiation into iMG through a streamlined two-step, 20-day process, producing iMG with a normal karyotype. We confirmed the iMG's authenticity and quality through single-cell RNA sequencing, chromatin accessibility profiles (ATAC-Seq), proteomics and functional tests. The toolkit also incorporates a drug-dependent CRISPR-ON/OFF system for temporally controlled gene expression. Further, we facilitate the use of multi-omic data by providing online searchable platform that compares new iMG profiles to human primary microglia: https://sherlab.shinyapps.io/IPSC-derived-Microglia/ . RESULTS: Our method generates iMG that closely align with human primary microglia in terms of transcriptomic, proteomic, and chromatin accessibility profiles. Functionally, these iMG exhibit Ca2 + transients, cytokine driven migration, immune responses to inflammatory signals, and active phagocytosis of CNS related substrates including synaptosomes, amyloid beta and myelin. Significantly, the toolkit facilitates repeated iMG harvesting, essential for large-scale experiments like CRISPR-Cas9 screens. The standalone ATAC-Seq profiles of our iMG closely resemble primary microglia, positioning them as ideal tools to study AD-associated single nucleotide variants (SNV) especially in the genome regulatory regions. CONCLUSIONS: Our advanced two-step protocol rapidly and efficiently produces authentic iMG. With features like the CRISPR-ON/OFF system and a comprehensive multi-omic data platform, our toolkit equips researchers for robust microglial functional genomic studies. By facilitating detailed SNV investigation and offering a sustainable cell harvest mechanism, the toolkit heralds significant progress in neurodegenerative disease drug research and therapeutic advancement.

Creation and evaluation of a self-directed, first-year intervention for pre-health undergraduates: setting students up for success.

University-established modalities to help undergraduate students navigate the path to medical school are often implemented toward the end of college or following graduation. This imposes cost and time burdens that may be contribute to the high rate of premedical attrition, especially for students who are members of a marginalized community. In the fall 2022 semester, an asynchronous, self-directed pre-health module was offered to biology majors at the University of North Carolina at Chapel Hill enrolled in a required introductory biology research skills course. The objective of the five-lesson intervention was to enhance student understanding of the path to becoming a successful applicant early in their college career. The module aimed to increase the accessibility of pre-health advising and was designed to be easily shared and adapted across various learning management systems. A pre- and post-module survey was administered to assess changes in students' perceived understanding of and confidence for success on the pre-health track following completion of the course.

Methionine inducing carbohydrate esterase secretion of Trichoderma harzianum enhances the accessibility of substrate glycosidic bonds.

BACKGROUND: The conversion of plant biomass into biochemicals is a promising way to alleviate energy shortage, which depends on efficient microbial saccharification and cellular metabolism. Trichoderma spp. have plentiful CAZymes systems that can utilize all-components of lignocellulose. Acetylation of polysaccharides causes nanostructure densification and hydrophobicity enhancement, which is an obstacle for glycoside hydrolases to hydrolyze glycosidic bonds. The improvement of deacetylation ability can effectively release the potential for polysaccharide degradation. RESULTS: Ammonium sulfate addition facilitated the deacetylation of xylan by inducing the up-regulation of multiple carbohydrate esterases (CE3/CE4/CE15/CE16) of Trichoderma harzianum. Mainly, the pathway of ammonium-sulfate's cellular assimilates inducing up-regulation of the deacetylase gene (Thce3) was revealed. The intracellular metabolite changes were revealed through metabonomic analysis. Whole genome bisulfite sequencing identified a novel differentially methylated region (DMR) that existed in the ThgsfR2 promoter, and the DMR was closely related to lignocellulolytic response. ThGsfR2 was identified as a negative regulatory factor of Thce3, and methylation in ThgsfR2 promoter released the expression of Thce3. The up-regulation of CEs facilitated the substrate deacetylation. CONCLUSION: Ammonium sulfate increased the polysaccharide deacetylation capacity by inducing the up-regulation of multiple carbohydrate esterases of T. harzianum, which removed the spatial barrier of the glycosidic bond and improved hydrophilicity, and ultimately increased the accessibility of glycosidic bond to glycoside hydrolases.

Disadvantaged groups have greater spatial access to pharmacies in New York state.

BACKGROUND: The accessibility of pharmacies has been associated with overall health and wellbeing. Past studies have suggested that low income and racial minority communities are underserved by pharmacies. However, the literature is inconsistent in finding links between area-level income or racial and ethnic composition and access to pharmacies. Here we aim to assess area-level spatial access to pharmacies across New York State (NYS), hypothesizing that Census Tracts with higher poverty rates and higher percentages of Black and Hispanic residents would have lower spatial access. METHODS: The population weighted mean shortest road network distance (PWMSD) to a pharmacy in 2018 was calculated for each Census Tract in NYS. This statistic was calculated from the shortest road network distance to a pharmacy from the centroid of each Census block within a tract, with the mean across census blocks weighted by the population of the census block. Cross-sectional analyses were conducted to assess links between Tract-level socio demographic characteristics and Tract-level PWMSD to a pharmacy. RESULTS: Overall the mean PWMSD to a pharmacy across Census tracts in NYS was 2.07 Km (SD = 3.35, median 0.85 Km). Shorter PWMSD to a pharmacy were associated with higher Tract-level % poverty, % Black/African American (AA) residents, and % Hispanic/Latino residents and with lower Tract-level % of residents with a college degree. Compared to tracts in the lowest quartile of % Black/AA residents, tracts in the highest quartile had a 70.7% (95% CI 68.3-72.9%) shorter PWMSD to a pharmacy. Similarly, tracts in the highest quartile of % poverty had a 61.3% (95% CI 58.0-64.4%) shorter PWMSD to a pharmacy than tracts in the lowest quartile. CONCLUSION: The analyses show that tracts in NYS with higher racial and ethnic minority populations and higher poverty rates have higher spatial access to pharmacies.

Study protocol for a type-II hybrid effectiveness-implementation trial to reach teenagers using mobile money shops to reduce unintended pregnancies in Uganda.

INTRODUCTION: Unintended teenage pregnancies have become a global public health challenge, particularly in sub-Saharan Africa. There is a notably high prevalence of unintended pregnancies among unmarried teenagers in Uganda. This study will develop an intervention programme using mobile money shops (vendors) as a platform to deliver sexual and reproductive health and rights (SRHR) services to teenagers and assess its effectiveness and scalability in Uganda. METHODS AND ANALYSES: This hybrid study comprises two integral components: an intervention study to assess the effectiveness of vendor-mediated intervention and implementation research to evaluate the implementation process. 30 vendors will be recruited for both intervention and control arms in 2 municipalities in Eastern Uganda, which have a high unintended pregnancy prevalence rate among unmarried teens aged 15-19 years. A preintervention and postintervention repeated survey involving 600 participants for each arm will be conducted over 4 months. The primary outcome is the rate of condom users among teenage vendor users. The secondary outcomes include the rate of preference for receiving SRHR services at vendors and knowledge regarding SRHR. A difference-in-differences analysis will be used to determine the effectiveness of the intervention. The Bowen model will be employed to evaluate the implementation design. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Ethics Review Committee of Uganda Christen University and JICA Ogata Sadako Research Institute for Peace and Development in Japan. The findings will be widely disseminated. This study was registered with the University Hospital Medical Information Network in Japan (UMIN000053332) on 12 January 2024. TRIAL REGISTRATION NUMBER: UMIN000053332.

How do people living with obesity who use obesity services perceive healthcare professionals' representation of the disease on social media? An interpretative phenomenological analysis.

OBJECTIVES: The objective of this study was to explore how people living with obesity who use obesity services perceive healthcare professionals' (HCPs) online representation of the disease on social media. By exploring their perspective, we aimed to develop a framework to inform good practice around social media use for HCPs. DESIGN: This was a qualitative study using a phenomenological framework. Following in-depth semi-structured interviews, analysis was undertaken to identify superordinate themes relating to how HCPs portray living with obesity online. SETTING: Patient advocacy organisation (The Irish Coalition for People Living with Obesity) and three clinical sites offering obesity treatment in Ireland. PARTICIPANTS: 15 adult participants comprising of 12 women and 3 men who use social media and are living with obesity and who use obesity services. RESULTS: Three key themes of how people living with obesity who use obesity services perceive HCP's online representation of the disease. (1) Negative experiences of HCPs-participants describe encountering weight stigma and bias on social media from HCPs that they characterised as simplistic and outdated conceptualisations. These engender shame, fear and anger. (2) Positive experience of HCPs-participants report social media allows HCPs to educate and inform public perception of obesity. Positive online experiences lead to feelings of inclusion, understanding and encouragement. (3) Expectations of HCPs-qualifications, professional titles and academic association affected the perceived trustworthiness of information and its impact on readers. Participants feel there is a duty of care for HCPs in obesity medicine to advocate and be active online to provide accurate medical information. CONCLUSION: HCP's use of social media has a powerful impact on people with obesity who use healthcare and obesity services. Social media is a key tool in obesity awareness and education. We propose the '3E' framework-Empower, Evidence-Based and Educate and be educated to guide HCPs' social media use.

Pretreatment of chitin depolymerization by expansin-like protein to improve hydrolysis efficiency.

Chitin is a polysaccharide similar to cellulose that contains abundant hydrogen bonds. Expansin-like proteins disrupt hydrogen bond networks, causing cellulose to swell and accelerating its degradation. We examined the effects of pretreatment with two expansin-like proteins, CxEXL22 (Arthrobotrys sp. CX1) and HcEXL (Hahella chejuensis), on chitin depolymerisation and enzymatic degradation. The efficiency of chitin degradation increased more than two-fold after pretreatment with expansin-like proteins. Following pretreatment with expansin-like proteins, chitin had a lower crystallinity index, greater d-spacing and crystallite size, and weaker hydrogen bonds, and the loosened porous microfibrils were more exposed than in untreated chitin. The rupture characterisation of crystalline chitin indicated that expansin-like proteins loosened the hydrogen bonds of the chitin polysaccharide chains, causing significant depolymerisation to expose more porous structures and enhance chitin accessibility.

Compliance with web content accessibility guidelines in ophthalmology social media posts.

This is a cross-sectional exploratory analysis of publicly available Internet data to examine compliance to web content accessibility guidelines (WCAG) on patient education social media posts in ophthalmology. WCAG ensures web content accessibility for those with disabilities (including visual impairment). A total of 100 social media posts were sampled from ten ophthalmology patient education social media pages and ten non-ophthalmology (cardiopulmonary) pages as the comparison group. Three independent graders evaluated the selected posts based on the WCAG 2 checklist by WebAIM, a non-profit affiliated with Utah State University, after its adaptation for social media posts. Validated accessibility standard labels: "0" for not meeting any standards, "1" or "A" for meeting bare minimum accessibility requirements, "2" or "AA" for meeting legal accessibility requirements, or "3" or "AAA" for exceeding accessibility requirements. There was not enough evidence to detect a difference in WCAG scores between ophthalmology and non-ophthalmology posts (p = 0.80). Forty-nine percent of scores for ophthalmology social media posts showed no compliance with any WCAG. The most common reasons that ophthalmology posts failed to meet criteria were due to color and contrast issues (39%). Most ophthalmology social media posts had low WCAG scores, indicating poor compliance to WCAG. Because social media is highly visual, reduced compliance to WCAG may create barriers for low vision individuals to successfully access patient education social media content.

Activated Carbon Derived from Cucumber Peel for Use as a Supercapacitor Electrode Material.

Biowaste conversion into activated carbon is a sustainable and inexpensive approach that relieves the pressure on its disposal. Here, we prepared micro-mesoporous activated carbons (ACs) from cucumber peels through carbonization at 600 °C followed by thermal activation at different temperatures. The ACs were tested as supercapacitors for the first time. The carbon activated at 800 °C (ACP-800) showed a high specific capacitance value of 300 F/g at a scan rate of 5 mV/s in the cyclic voltammetry and 331 F/g at the current density of 0.1 A/g in the galvanostatic charge-discharge analysis. At the current density of 1 A/g, the specific discharge capacitance was 286 F/g and retained 100% capacity after 2000 cycles. Their properties were analyzed by scanning electron microscopy, energy-dispersive X-ray analysis, porosity, thermal analysis, and Fourier-transform infrared spectroscopy. The specific surface area of this sample was calculated to be 2333 m2 g-1 using the Brunauer-Emmett-Teller method. The excellent performance of ACP-800 is mainly attributed to its hierarchical porosity, as the mesopores provide connectivity between the micropores and improve the capacitive performance. These electrochemical properties enable this carbon material prepared from cucumber peels to be a potential source for supercapacitor materials.

HIV knowledge and access to testing for people with and without disabilities in low- and middle-income countries: evidence from 37 Multiple Indicator Cluster Surveys.

INTRODUCTION: Disability and HIV are intricately linked, as people with disabilities are at higher risk of contracting HIV, and living with HIV can lead to impairments and disability. Despite this well-established relationship, there remains limited internationally comparable evidence on HIV knowledge and access to testing for people with disabilities. METHODS: We used cross-sectional data from 37 Multiple Indicator Cluster Surveys. Surveys were from six UNICEF regions, including East Asia and Pacific (n = 6), East and Central Asia (n = 7), Latin America and the Caribbean (n = 6), Middle East and North Africa (n = 4), South Asia (n = 2) and sub-Saharan Africa (n = 12). A total of 513,252 people were eligible for inclusion, including 24,695 (4.8%) people with disabilities. We examined risk ratios and 95% confidence intervals for key indicators on HIV knowledge and access to testing for people with disabilities by sex and country. We also conducted a meta-analysis to get a pooled estimate for each sex and indicator. RESULTS: Men and women with disabilities were less likely to have comprehensive knowledge about HIV prevention (aRR: 0.74 [0.67, 0.81] and 0.75 [0.69, 0.83], respectively) and to know of a place to be tested for HIV (aRR: 0.95 [0.92, 0.99] and 0.94 [0.92, 0.97], respectively) compared to men and women without disabilities. Women with disabilities were also less likely to know how to prevent mother-to-child transmission (aRR: 0.87 [0.81, 0.93]) and ever have been tested for HIV (aRR: 0.90 [0.85, 0.94]). CONCLUSIONS: Men and women with disabilities have lower overall HIV knowledge and in particular women with disabilities also indicate lower testing rates. Governments must include people with disabilities in HIV programmes by improving disability-inclusion and accessibility to HIV-related information, education and healthcare services.

Search engine optimization and its association with readability and accessibility of diabetic retinopathy websites.

PURPOSE: This study investigated whether websites regarding diabetic retinopathy are readable for patients, and adequately designed to be found by search engines. METHODS: The term "diabetic retinopathy" was queried in the Google search engine. Patient-oriented websites from the first 10 pages were categorized by search result page number and website organization type. Metrics of search engine optimization (SEO) and readability were then calculated. RESULTS: Among the 71 sites meeting inclusion criteria, informational and organizational sites were best optimized for search engines, and informational sites were the most visited. Better optimization as measured by authority score was correlated with lower Flesch Kincaid Grade Level (r = 0.267, P = 0.024). There was a significant increase in Flesch Kincaid Grade Level with successive search result pages (r = 0.275, P = 0.020). Only 2 sites met the 6th grade reading level AMA recommendation by Flesch Kincaid Grade Level; the average reading level was 10.5. There was no significant difference in readability between website categories. CONCLUSION: While the readability of diabetic retinopathy patient information was poor, better readability was correlated to better SEO metrics. While we cannot assess causality, we recommend websites improve their readability, which may increase uptake of their resources.

Federal food assistance accessibility and acceptability among Indigenous Peoples in the United States: A scoping review.

The purpose of this scoping review was to determine the extent to which accessibility and acceptability of federal food assistance programs in the United States (U.S.) have been evaluated among Indigenous Peoples, and to summarize what is currently known. Twelve publications were found that examine aspects of accessibility or acceptability by indigenous peoples of one or more federal food assistance programs, including the Supplemental Nutrition Assistance Program (SNAP) and/or the Food Distribution Program on Indian Reservations (FDPIR) (n=8), the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) (n=3), and the National School Lunch Program (NSLP) (n=1). No publications were found to include the Commodity Supplemental Food Program (CSFP) or the Child and Adult Care Food Program (CACFP). Publications ranged in time from 1990 - 2023, and all reported on findings from rural populations, while three also included urban settings. Program accessibility varied by program type and geographic location. Road conditions, transportation access, telephone and internet connectivity, and overall number of food stores were identified as key access barriers to SNAP and WIC benefit redemption in rural areas. Program acceptability was attributed to factors such as being tribally administered, providing culturally sensitive services, and offering foods of cultural significance. For these reasons, FDPIR and WIC were more frequently described as acceptable compared to SNAP and NSLP. However, SNAP was occasionally described as more acceptable than other assistance programs because it allows participants autonomy to decide which foods to purchase and when. Overall, little attention has been paid to the accessibility and acceptability of federal food assistance programs among Indigenous Peoples in the U.S. More research is needed to understand and improve the participation experiences and health trajectories of these priority populations.

Primary care dentistry: An Australian perspective.

INTRODUCTION: Primary care dentistry is the first point of contact that someone has with the dental system and is predominantly focused on the treatment and prevention of dental caries and periodontal disease. The aim of this paper was to review the Australian primary dental care system. METHODS: This paper reviews the primary dental care system in Australia, drawing on data reporting on the dental workforce, funding sources for dental care, oral health outcome measures and dental visiting patterns. RESULTS: Primary dental health care in Australia is predominantly provided by dentists working in private practice, with the number of dentists per 100,000 people in Australia increasing from 46.9 in 2000 to 65.1 in 2022. However, there has been a gradual shift over the past twenty years towards greater service provision by other members of the dental team who now represent one quarter of the dental workforce, and some expansion of publicly funded dental care. Despite this dentistry remains isolated from the rest of primary health care, and the lack of government funding means that many people continue to miss out of necessary dental care, particularly those living in regional and rural Australia and from low-income groups. CONCLUSIONS: Australians should be able to access primary dental care services when and where they need it with adequate financial protection, from services that are well integrated into the broader primary health care system to ensure they are able to achieve optimal oral and general health. For many Australians, this is not currently the case. CLINICAL SIGNIFICANCE: Australia is at a crossroads with respect to access to dental care, and there is a need for stronger advocacy from stakeholders to improve oral health outcomes and reduce inequalities.

A Multidisciplinary Assessment of ChatGPT's Knowledge of Amyloidosis: Observational Study.

BACKGROUND: Amyloidosis, a rare multisystem condition, often requires complex, multidisciplinary care. Its low prevalence underscores the importance of efforts to ensure the availability of high-quality patient education materials for better outcomes. ChatGPT (OpenAI) is a large language model powered by artificial intelligence that offers a potential avenue for disseminating accurate, reliable, and accessible educational resources for both patients and providers. Its user-friendly interface, engaging conversational responses, and the capability for users to ask follow-up questions make it a promising future tool in delivering accurate and tailored information to patients. OBJECTIVE: We performed a multidisciplinary assessment of the accuracy, reproducibility, and readability of ChatGPT in answering questions related to amyloidosis. METHODS: In total, 98 amyloidosis questions related to cardiology, gastroenterology, and neurology were curated from medical societies, institutions, and amyloidosis Facebook support groups and inputted into ChatGPT-3.5 and ChatGPT-4. Cardiology- and gastroenterology-related responses were independently graded by a board-certified cardiologist and gastroenterologist, respectively, who specialize in amyloidosis. These 2 reviewers (RG and DCK) also graded general questions for which disagreements were resolved with discussion. Neurology-related responses were graded by a board-certified neurologist (AAH) who specializes in amyloidosis. Reviewers used the following grading scale: (1) comprehensive, (2) correct but inadequate, (3) some correct and some incorrect, and (4) completely incorrect. Questions were stratified by categories for further analysis. Reproducibility was assessed by inputting each question twice into each model. The readability of ChatGPT-4 responses was also evaluated using the Textstat library in Python (Python Software Foundation) and the Textstat readability package in R software (R Foundation for Statistical Computing). RESULTS: ChatGPT-4 (n=98) provided 93 (95%) responses with accurate information, and 82 (84%) were comprehensive. ChatGPT-3.5 (n=83) provided 74 (89%) responses with accurate information, and 66 (79%) were comprehensive. When examined by question category, ChatGTP-4 and ChatGPT-3.5 provided 53 (95%) and 48 (86%) comprehensive responses, respectively, to "general questions" (n=56). When examined by subject, ChatGPT-4 and ChatGPT-3.5 performed best in response to cardiology questions (n=12) with both models producing 10 (83%) comprehensive responses. For gastroenterology (n=15), ChatGPT-4 received comprehensive grades for 9 (60%) responses, and ChatGPT-3.5 provided 8 (53%) responses. Overall, 96 of 98 (98%) responses for ChatGPT-4 and 73 of 83 (88%) for ChatGPT-3.5 were reproducible. The readability of ChatGPT-4's responses ranged from 10th to beyond graduate US grade levels with an average of 15.5 (SD 1.9). CONCLUSIONS: Large language models are a promising tool for accurate and reliable health information for patients living with amyloidosis. However, ChatGPT's responses exceeded the American Medical Association's recommended fifth- to sixth-grade reading level. Future studies focusing on improving response accuracy and readability are warranted. Prior to widespread implementation, the technology's limitations and ethical implications must be further explored to ensure patient safety and equitable implementation.

The role of increasing synchronous telehealth use during the COVID-19 pandemic on disparities in access to healthcare: A systematic review.

INTRODUCTION: The COVID-19 public health emergency led to an unprecedented rapid increase in telehealth use, but the role of telehealth in reducing disparities in access to care has been questioned. The objective of this study was to conduct a systematic review to summarize the available evidence on how telehealth during the COVID-19 pandemic was associated with telehealth utilization for minority groups and its role in health disparities. METHODS: We conducted a systematic review focused on health equity and access to care by searching for interventional and observational studies using the following four search domains: telehealth, COVID-19, health equity, and access to care. We searched PubMed, Embase, Cochrane CENTRAL, CINAHL, telehealth.hhs.gov, and the Rural Health Research Gateway, and included any study that reported quantitative results with a control group. RESULTS: Our initial search yielded 1970 studies, and we included 48 in our final review. The most common dimensions of health equity studied were race/ethnicity, rurality, insurance status, language, and socioeconomic status, and the telehealth applications studied were diverse. Included studies had a moderate risk of bias. In aggregate, most studies reported increased telehealth use during the pandemic, with the greatest increase in non-minority populations, including White, younger, English-speaking people from urban areas. DISCUSSION: We found that despite rapid adoption and increased telehealth use during the public health emergency, telehealth did not reduce existing disparities in access to care. We recommend that future work measuring the impact of telehealth focus on equity so that features of telehealth innovation can reduce disparities in health outcomes.

Indigenous people's experiences of primary health care in Canada: a qualitative systematic review. / Expériences des Autochtones en matière de soins de santé primaires au Canada : revue systématique qualitative.

INTRODUCTION: Indigenous people in Canada encounter negative treatment when accessing primary health care (PHC). Despite several qualitative accounts of these experiences, there still has not been a qualitative review conducted on this topic. In this qualitative systematic review, we aimed to explore Indigenous people's experiences in Canada with PHC services, determine urban versus rural or remote differences and identify recommendations for quality improvement. METHODS: This review was guided by the Joanna Briggs Institute's methodology for systematic reviews of qualitative evidence. MEDLINE, CINAHL, PubMed, PsycInfo, Embase and Web of Science as well as grey literature and ancestry sources were used to identify relevant articles. Ancestry sources were obtained through reviewing the reference lists of all included articles and determining the ones that potentially met the eligibility criteria. Two independent reviewers conducted the initial and full text screening, data extraction and quality assessment. Once all data were gathered, they were synthesized following the meta-aggregation approach (PROSPERO CRD42020192353). RESULTS: The search yielded a total of 2503 articles from the academic databases and 12 articles from the grey literature and ancestry sources. Overall, 22 articles were included in this review. Three major synthesized findings were revealed-satisfactory experiences, discriminatory attitudes and systemic challenges faced by Indigenous patients-along with one synthesized finding on their specific recommendations. CONCLUSION: Indigenous people value safe, accessible and respectful care. The discrimination and racism they face negatively affect their overall health and well-being. Hence, it is crucial that changes in health care practice, structures and policy development as well as systemic transformation be implemented immediately.

Adolescents' perspectives and experiences of accessing general practitioner services: A systematic review.

Adolescents face issues regarding physical health, mental health, sexual health, drug and alcohol problems, stress, and peer pressure. Little is known about adolescents' help-seeking behaviours in relation to health concerns. The general practitioner (GP) is usually the first point of contact for adolescents. The aim of this systematic review was to identify, describe, and summarize evidence on barriers and enablers experienced by adolescents when accessing GP-led primary care services. Systematic searches using four electronic databases (PsycINFO, MEDLINE, CINAHL, and SocINDEX) were conducted and the quality of the included studies was appraised. Six studies were included in this review. Findings indicate that barriers to GP access relate to trust, confidentiality, privacy, and communication. Adolescents also reported barriers such as transport, cost, and lack of information. Adolescents reported enablers being services that are sensitive to their needs, healthcare professionals who understand them, and services that are flexible regarding out of hours access. Listening to and acting on the voice of adolescents is important to developing youth-friendly services.

Experiencing accessibility of historical heritage places with individuals living with visible and invisible disabilities.

Introduction: Around 16% of world's population lives with visible and invisible disabilities. People with disabilities' participation may be limited because of the environmental obstacles. Moreover, historic heritage places were built before the development of accessibility standards and the rights of people living with disabilities and the majority were not designed to be accessible. Access to historic heritage places is important for carrying out the activities in place but also to create and reinforce identity. The aim of this study was to explore the experiences of people with visible and invisible disabilities when visiting heritage sites considering accessibility issues. Methods: This study is a qualitative interpretive description. Participants were adults with visible (e.g., motor disability) or invisible (e.g., autism) disabilities. For data collection, go along interviews (also referred to in the literature as "walking interview" in two different locations in the Historic District of Old Quebec in Quebec City were conducted. Thematic analysis was done. Results: Twenty-one participants completed two go along interviews: one in the Séminaire de Québec (Seminary of Quebec City) and the other in Petit-Champlain and Place Royale areas of Quebec City. Three themes emerged: (1) Obstacles and impact on participation; (2) Disabling accessibility; and (3) Heritage meaning. Discussion: The barriers identified by participants are diverse and differ according to the person and the type of disability. However, social and leisure activities were particularly limited, despite the strategies developed by some participants. Participants in the study demonstrated an interest in accessing to heritage places, therefore it seems essential to consider the needs of people with disabilities when developing accessibility solutions, and to seek a balance between preserving heritage and promoting inclusive and equitable access for all.

scifi-ATAC-seq: massive-scale single-cell chromatin accessibility sequencing using combinatorial fluidic indexing.

Single-cell ATAC-seq has emerged as a powerful approach for revealing candidate cis-regulatory elements genome-wide at cell-type resolution. However, current single-cell methods suffer from limited throughput and high costs. Here, we present a novel technique called scifi-ATAC-seq, single-cell combinatorial fluidic indexing ATAC-sequencing, which combines a barcoded Tn5 pre-indexing step with droplet-based single-cell ATAC-seq using the 10X Genomics platform. With scifi-ATAC-seq, up to 200,000 nuclei across multiple samples can be indexed in a single emulsion reaction, representing an approximately 20-fold increase in throughput compared to the standard 10X Genomics workflow.
