CHARACTERIZATION OF MODERATE AND SEVERE ASTHMA EXACERBATIONS IN THE CAPTAIN STUDY.

BACKGROUND: Limited data exist on the relative impact of moderate and severe exacerbations on asthma control and impairment. OBJECTIVE: To explore data from the CAPTAIN trial to evaluate the relationship between first moderate or severe exacerbation and changes in lung function, symptoms, physical activity limitation scores, and short-acting ß2-agonist (SABA) usage to determine the clinical relevance of moderate events. METHODS: CAPTAIN was a Phase IIIA 24-52-week, multicenter, international, randomized controlled trial evaluating efficacy and safety of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus FF/VI in patients with uncontrolled asthma on inhaled corticosteroid/long-acting ß2-agonist. Outcomes reportedinclude: first post-randomization exacerbation event by severity (Weeks 1-52), frequency and duration of moderate and severe exacerbations and time course of changes over ±14-day peri-exacerbation period for lung function, symptoms, limitations, and SABA use. RESULTS: Of the intent-to-treat population (N=2436), 550 patients (23%) continued to 52 weeks. There were 529 moderate and 546 severe exacerbations. Lung function changes were similar, but symptom, physical activity limitation scores, and SABA use were higher, for severe versus moderate exacerbations. Lung function decline preceded increases in symptom, physical activity limitation scores, and SABA use, irrespective of exacerbation severity. Lung function variables, limitation scores, and SABA use returned to pre-exacerbation baseline after ∼8-12 days for both exacerbation severities. CONCLUSION: While severe events were associated with greater impact on symptoms, physical activity limitations, and SABA use, onset and time to resolution were generally similar for moderate and severe events. Both exacerbation severities represent clinically important deteriorations comprising clinical and functional changes. NCT02924688.

Optimal Tai Chi forms in knee osteoarthritis: An exploration from biomechanical rationale to pain reduction.

Objectives: Tai Chi (TC) shows some beneficial effects in reducing pain in knee osteoarthritis (OA). However, the selection of criteria TC forms in previous studies were unclear and inconsistent, possibly accounting for the varying outcomes and rendering the training effects suboptimal. We have selected four optimal TC (OTC) forms based on the knee joint load and its association with pain. This pilot study sought to examine the effect of the OTC forms on reducing knee pain in individuals with knee OA. Methods: Fifteen knee OA participants were recruited. Their knee joint pain level was rated by using the Visual Analogue Scale before and after two weeks of OTC training and compared between these two assessments. Results: The two-week OTC training course was well accepted by our participants. The knee OA pain showed a significant reduction (median pain score: 5 â€‹cm before training and 1 â€‹cm post-training, Wilcoxon p â€‹< â€‹0.001) after the two-week training program. Conclusions: Our pilot results revealed that the 2-week four-form-based OTC program could significantly reduce the knee pain level in people with knee OA. Additionally, our OTC program appears to be about 50% more effective in reducing knee pain than the existing TC-based program, which uses 10 â€‹TC forms over 12 weeks (1.59 vs. 1.06 in Hedge's g). The findings in this study may inform the development of OTC-based knee pain reduction programs and the design of relevant clinical trials to establish OTC's effectiveness, safety, and dose-response relationship in easing knee OA pain.

Experiences of Aging with Opioid Use Disorder and Comorbidity in Opioid Treatment Programs: A Qualitative Analysis.

BACKGROUND: The number of older adults entering opioid treatment programs (OTPs) to treat opioid use disorder (OUD) is increasing. However, the lived experiences of aging in OTPs have not been examined. OBJECTIVE: To explore the aging experience with OUD and barriers to medical care for older adults who receive care in OTPs. DESIGN: From November 2021 to July 2022, we conducted 1-to-1, semi-structured qualitative interviews in English and Spanish, audio-recorded, transcribed, systematically coded, and analyzed to identify key themes regarding the challenges of aging with OUD and managing chronic diseases. PARTICIPANTS: Thirty-six adults aged ≥ 55 enrolled in OTPs in San Diego, California. APPROACH: A descriptive qualitative approach was used. Major themes and subthemes were identified through thematic analysis until thematic saturation was reached. KEY RESULTS: All participants were on methadone and had a mean age of 63.4 (SD 5.1) years; 11 (30.6%) identified as female, 14 (39%) as Hispanic/Latino, and 11 (36%) as Black, with a mean duration of methadone treatment of 5.6 years. Chronic diseases were common, with 21 (58.3%) reporting hypertension, 9 (25%) reporting untreated hepatitis C, and 32 (88.9%) having ≥ 2 chronic diseases. Three major themes emerged: (1) avoidance of medical care due to multiple intersectional stigmas, including those related to drug use, substance use disorder (SUD) treatment, ageism, and housing insecurity; (2) increasing isolation with aging and loss of family and peer groups; (3) the urgent need for integrating medical and aging-focused care with OUD treatment in the setting of increasing health and functional challenges. CONCLUSIONS: Older adults with OUD reported increasing social isolation and declining health while experiencing multilevel stigma and discrimination. The US healthcare system must transform to deliver age-friendly care that integrates evidence-based geriatric models of care incorporated with substance use disorder treatment and addresses the intersectional stigma this population has experienced in healthcare settings.

Variation in Receipt of Cancer Screening and Immunizations by 10-year Life Expectancy among U.S. Adults aged 65 or Older in 2019.

IMPORTANCE: The likelihood of benefit from a preventive intervention in an older adult depends on its time-to-benefit and the adult's life expectancy. For example, the time-to-benefit from cancer screening is >10 years, so adults with <10-year life expectancy are unlikely to benefit. OBJECTIVE: To examine receipt of screening for breast, prostate, or colorectal cancer and receipt of immunizations by 10-year life expectancy. DESIGN: Analysis of 2019 National Health Interview Survey. PARTICIPANTS: 8,329 non-institutionalized adults >65 years seen by a healthcare professional in the past year, representing 46.9 million US adults. MAIN MEASURES: Proportions of breast, prostate, and colorectal cancer screenings, and immunizations, were stratified by 10-year life expectancy, estimated using a validated mortality index. We used logistic regression to examine receipt of cancer screening and immunizations by life expectancy and sociodemographic factors. KEY RESULTS: Overall, 54.7% of participants were female, 41.4% were >75 years, and 76.4% were non-Hispanic White. Overall, 71.5% reported being current with colorectal cancer screening, including 61.4% of those with <10-year life expectancy. Among women, 67.0% reported a screening mammogram in the past 2 years, including 42.8% with <10-year life expectancy. Among men, 56.8% reported prostate specific antigen screening in the past two years, including 48.3% with <10-year life expectancy. Reported receipt of immunizations varied from 72.0% for influenza, 68.8% for pneumococcus, 57.7% for tetanus, and 42.6% for shingles vaccination. Lower life expectancy was associated with decreased likelihood of cancer screening and shingles vaccination but with increased likelihood of pneumococcal vaccination. CONCLUSIONS: Despite the long time-to-benefit from cancer screening, in 2019 many US adults age >65 with <10-year life expectancy reported undergoing cancer screening while many did not receive immunizations with a shorter time-to-benefit. Interventions to improve individualization of preventive care based on older adults' life expectancy may improve care of older adults.

Trends in past-month cannabis use among US adults across a range of disabilities and health conditions, 2015-2019.

INTRODUCTION: While there is increasing interest in the use of cannabis to manage a range of health-related symptoms, little is known about trends in recent cannabis use with respect to various health conditions. METHODS: We examined data from a US representative sample of noninstitutionalized adults age ≥ 18 from the 2015-2019 National Survey on Drug Use and Health (N = 214,505). We estimated the pooled prevalences followed by linear time trends, overall, and by disability (i.e., difficulty hearing, seeing, thinking, walking, dressing, doing errands) and lifetime (i.e., bronchitis, cancer, diabetes, hepatitis, kidney disease) and current (i.e., asthma, depression, heart disease, hypertension) health condition status using logistic regression. Models with year-by-condition status interaction terms were used to assess differential time trends, adjusting for demographic characteristics. RESULTS: From 2015 to 2019, cannabis use increased significantly among adults with and without each disability and health condition examined. However, the increase was more rapid among those with (versus without) difficulty hearing (89.8% increase [4.9% to 9.3%] vs. 37.9% increase [8.7% to 12.0%], p = 0.015), difficulty walking (84.1% increase [6.3% to 11.6%] vs. 36.8% increase [8.7% to 11.9%], p < 0.001), 2-3 impairments (75.3% increase [9.3% to 16.3%] vs. 36.6% increase [8.2% to 11.2%], p = 0.041), and kidney disease (135.3% increase [3.4% to 8.0%] vs. 38.4% increase [8.6% to 11.9%], p = 0.045). CONCLUSION: Given the potential adverse effects of cannabis, prevention and harm reduction efforts should focus on groups at increasingly higher risk for use, including those with disabilities and kidney disease.

The role of the multiple Index of deprivation in predicting mental health outcomes after the COVID-19 pandemic in adolescents: a cross-sectional study.

BACKGROUND: The number of children and young people (CYP) diagnosed with mental health problems has increased over the past decade. The COVID-19 pandemic also has accelerated this increase, raising significant concerns about adolescent emotional wellbeing. Research suggests that adolescents who live in more deprived areas are more likely to experience poor emotional wellbeing. Children in the northwest of England are among those with the poorest outcomes in the UK. We aimed to investigate the association between deprivation and mental health outcomes from 2019 to 2022. The aim was to support local authorities with targeted provision of public health services as well as predicting service need for 2022 onwards. METHODS: In this cross-sectional study, we analysed routinely collected Schools Health Needs Assessment (SHNA) data. The School Health Needs Assessment dataset contained 32 676 responses from Year 6 (ages 10-11 years) and Year 9 (ages 13-14 years) who completed the annual survey in 2019-22. The questionnaire was offered to all mainstream schools, delivered by the public health school nursing service. Index of multiple deprivation (IMD) data were provided for household postcodes. Data were analysed using IBM SPSS. Factor analysis created a composite emotional wellbeing scale (EWS) and estimates generated by school year (Years 6 and 9) and three academic years (2019-22). We calculated correlations between IMD and EWS overall and within school and academic year samples. FINDINGS: The final total sample across the three consecutive survey years and the two school years was 32 659. The sample consisted of 15 932 (49%) female students and 5066 (16%) students who registered at school as from an ethnic minority. Of the total sample, 9209 (28%) lived in a postcode in the most deprived IMD quintile in England. There was an overall decrease in EWS from Year 6 to Year 9 and from 2019 to 2022. The Year 6 students in 2022 reported mean levels of EWS equivalent to Year 9 students in 2019 indicating a shift toward poorer mental health in younger children. The correlational analyses showed no significant associations between IMD and EWS scores within the school or academic year cohorts. A follow-up analysis of children in receipt or not in receipt of free school meals also showed no significant association with EWS scores. INTERPRETATION: Findings showed that the emotional wellbeing of children and young people in the northwest of England has deteriorated since 2019, with greatest changes observed in the younger cohort of children in Year 6. This was not explained by postcode-based indices of multiple deprivation. Although it is recognised that deprivation is both a cause and a result of poor mental health, policy decisions on service provision for children and young people should not be based solely on IMD or receipt of free school meals. A rapid response is required to address the decline in emotional wellbeing currently observed in younger children of the northwest of England. FUNDING: None.

Reflecting on parental insights into healthy lifestyles: a qualitative study.

BACKGROUND: Children living in the most deprived regions are more than twice as likely as their affluent peers to be obese. One way we can explain the social gradient of health (determined by relative position on the scale of social disadvantage or advantage) is by identifying the barriers and drivers to health that different groups of people experience. This study explored the understanding and perceptions of (and barriers and drivers to) a healthy lifestyle to investigate how commissioned services can better support residents to enable behaviour change in an area of high social deprivation. This community engagement activity was also conducted to inform commissioning decisions in children's public health services. METHODS: We used a qualitative study design with a semi-structured interview schedule. Four focus groups (5-8 participants, n=26) were conducted in an area of high deprivation in northwest England. Parents or carers were invited to attend anonymously by the Public Health Community Engagement Officer (in June 2022). The inclusion criteria were previous attendance on a weight management programme. Data were analysed using thematic analysis. Engagement activities do not require ethics approval. All participants provided written informed consent to take part. No further information was collected about personal characteristics. FINDINGS: The study participants demonstrated an awareness and understanding of factors affecting child and family health and health behaviours: healthy eating, exercise, mental health and emotional wellbeing, family values and attitudes towards a healthy lifestyle, cooking and budgeting, wider social connections, access to open spaces, availability of local activities, costs (including hidden costs), and structural barriers. INTERPRETATION: Using the finding that participants recognise barriers and drivers to behaviour change beyond knowledge and skills, we reflect on why there was no take up for a commissioned intervention that aimed to address childhood obesity in the Lancashire area. These reflections inform arguments for an alternative model of service commission that relies less on established randomised trial evidence base and more on participatory codesign and a place-based approach (working with populations' existing knowledge and skills) and is particularly sensitive to people's own perception of the specific drivers and barriers they experience to behaviour change. Limitations include sampling from an area with low diversity and selection of participants who have previously agreed to uptake a weight management intervention. FUNDING: None.

Latent human herpesvirus 6 is reactivated in CAR T cells.

Cell therapies have yielded durable clinical benefits for patients with cancer, but the risks associated with the development of therapies from manipulated human cells are understudied. For example, we lack a comprehensive understanding of the mechanisms of toxicities observed in patients receiving T cell therapies, including recent reports of encephalitis caused by reactivation of human herpesvirus 6 (HHV-6)1. Here, through petabase-scale viral genomics mining, we examine the landscape of human latent viral reactivation and demonstrate that HHV-6B can become reactivated in cultures of human CD4+ T cells. Using single-cell sequencing, we identify a rare population of HHV-6 'super-expressors' (about 1 in 300-10,000 cells) that possess high viral transcriptional activity, among research-grade allogeneic chimeric antigen receptor (CAR) T cells. By analysing single-cell sequencing data from patients receiving cell therapy products that are approved by the US Food and Drug Administration2 or are in clinical studies3-5, we identify the presence of HHV-6-super-expressor CAR T cells in patients in vivo. Together, the findings of our study demonstrate the utility of comprehensive genomics analyses in implicating cell therapy products as a potential source contributing to the lytic HHV-6 infection that has been reported in clinical trials1,6-8 and may influence the design and production of autologous and allogeneic cell therapies.

Ascertaining Whether an Intelligent Voice Assistant Can Meet Older Adults' Health-Related Needs in the Context of a Geriatrics 5Ms Framework.

The Geriatrics 5Ms: Medications, Mind, Mobility, what Matters most and Multicomplexity is a framework to address the complex needs of older adults. Intelligent Voice Assistants (IVAs) are increasingly popular and have potential to support health-related needs of older adults. We utilized previously collected qualitative data on older adults' views of how an IVA may address their health-related needs and ascertained their fit into the Geriatrics 5Ms framework. The codes describing health challenges and potential IVA solutions fit the framework: (1) Medications: difficulty remembering medications. SOLUTION: reminders. (2) Mind: isolation, anxiety, memory loss. SOLUTION: companionship, memory aids. (3) Mobility: barriers to exercise. SOLUTION: incentives, exercise ideas. (4) Matters most: eating healthy foods. SOLUTION: suggest and order nutritious foods, (5) Multicomplexity; managing multimorbidity. SOLUTION: symptom tracking and communicating with health care professionals. Incorporating the 5Ms framework into IVA design can aid in addressing health care priorities of older adults.

Substance use and pre-hospital crash injury severity among U.S. older adults: A five-year national cross-sectional study.

BACKGROUND: Alcohol and drug use (substance use) is a risk factor for crash involvement. OBJECTIVES: To assess the association between substance use and crash injury severity among older adults and how the relationship differs by rurality/urbanicity. METHODS: We pooled 2017-2021 cross-sectional data from the United States National Emergency Medical Service (EMS) Information System. We measured injury severity (low acuity, emergent, critical, and fatal) predicted by substance use, defined as self-reported or officer-reported alcohol and/or drug use. We controlled for age, sex, race/ethnicity, road user type, anatomical injured region, roadway crash, rurality/urbanicity, time of the day, and EMS response time. We performed a partial proportional ordinal logistic regression and reported the odds of worse injury outcomes (emergent, critical, and fatal injuries) compared to low acuity injuries, and the predicted probabilities by rurality/urbanicity. RESULTS: Our sample consisted of 252,790 older adults (65 years and older) road users. Approximately 67%, 25%, 6%, and 1% sustained low acuity, emergent, critical, and fatal injuries, respectively. Substance use was reported in approximately 3% of the population, and this proportion did not significantly differ by rurality/urbanicity. After controlling for patient, crash, and injury characteristics, substance use was associated with 36% increased odds of worse injury severity. Compared to urban areas, the predicted probabilities of emergent, critical, and fatal injuries were higher in rural and suburban areas. CONCLUSION: Substance use is associated with worse older adult crash injury severity and the injury severity is higher in rural and suburban areas compared to urban areas.

The disproportionate burden of Alzheimer's disease and related dementias (ADRD) in diverse older adults diagnosed with cancer.

INTRODUCTION: Older adults living with Alzheimer's disease and related dementias (ADRD) who are then diagnosed with cancer are an understudied population. While the role of cognitive impairment during and after cancer treatment have been well-studied, less is understood about patients who are living with ADRD and then develop cancer. The purpose of this study is to contribute evidence about our understanding of this vulnerable population. MATERIALS AND METHODS: This was a retrospective cohort study of a linked, representative family of databases of cancer registries and Medicare administrative claims that make up the SEER-Medicare database. Older adults ages 68 and older with a first primary cancer type: breast, cervical, colorectal, lung, oral, or prostate were eligible for inclusion (N = 337,932). Prevalence estimates of ADRD across cancer types and a 5% non-cancer comparison sample were compared by patient factors. RESULTS: The overall prevalence of patients who had an ADRD diagnosis anytime in the three years prior to their cancer diagnosis was 5.6%. Patients with ADRD were more likely to be female, older (over age 75), a racial/ethnic minority, single, with multiple chronic conditions, and a tumor diagnosed early (stage I) or were unstaged. Black patients with colorectal and oral cancer had the highest and second highest prevalence of ADRD compared to White patients (13.46% vs 7.95% and 12.64% vs 7.82% respectively, p < .0001). We observed the highest prevalence of ADRD among Black patients for breast (11.85%), cervical (11.98%), lung (8.41%), prostate (4.83), and the 5% sample (9.50%, p > .0001). DISCUSSION: The higher prevalence of ADRD among Black and Latine older adults with cancer not only aligns with the trend observed in our non-cancer comparison sample, but also, these findings demonstrate the compounded risk experienced by minoritized older adults over the life course. The greater than expected prevalence of patients with ADRD who go on to develop cancer demonstrates better assessment of cognition is urgently needed. Accurate identification of these vulnerable populations is critical to improve assessment, care coordination, and address inequities in screening and treatment planning.

Adolescents and young adults communicating with gastroenterologists: variation in inflammatory bowel disease clinical communication.

OBJECTIVES: This study explored the variation in emerging adults' communication with gastroenterologists around the management of inflammatory bowel disease (IBD). METHODS: Nineteen emerging adults with IBD aged 18-25 and seven gastroenterologists participated in the study. Outpatient specialist consultations of consenting participants were audio-recorded and transcribed. Transcribed consultations were analysed in terms of the linguistic structure of the consultations and the gastroenterologist-patient role relationship. RESULTS: Variations in the emerging adults' communication with their gastroenterologists stem partly from variation in their ability, opportunity, or need to contribute to the different phases of the consultation and partly from variations in the gastroenterologists' style of communication. Gastroenterologists differed in the construction of their role relationship with the patient, resulting in variations in employing empowering strategies including eliciting, exploring, and clarifying the patient's concerns, sharing clinical reasoning, and validating the patient experience. Variations were also observed in the length of appointments and the gastroenterologists' assessment and addressing of adherence issues. Techniques used by the gastroenterologist varied (1) from simply confirming adherence, to a comprehensive assessment of the patient's understanding of their management plan and their feedback, and (2) from use of persuasion to values calibration. CONCLUSIONS: Evidence-based consumer interventions and communication guidelines for clinicians are needed to address the identified variations in providing care to emerging adults living with chronic conditions.

Development and Validation of an ICU Delirium Playbook for Provider Education.

Although delirium detection and prevention practices are recommended in critical care guidelines, there remains a persistent lack of effective delirium education for ICU providers. To address this knowledge-practice gap, we developed an "ICU Delirium Playbook" to educate providers on delirium detection (using the Confusion Assessment Method for the ICU) and prevention. DESIGN: Building on our previous ICU Delirium Video Series, our interdisciplinary team developed a corresponding quiz to form a digital "ICU Delirium Playbook." Playbook content validity was evaluated by delirium experts, and face validity by an ICU nurse focus group. Additionally, focus group participants completed the quiz before and after video viewing. Remaining focus group concerns were evaluated in semi-structured follow-up interviews. SETTING: Online validation survey, virtual focus group, and virtual interviews. SUBJECTS: The validation group included six delirium experts in the fields of critical care, geriatrics, nursing, and ICU education. The face validation group included nine ICU nurses, three of whom participated in the semi-structured feedback interviews. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The 44-question quiz had excellent content validity (average scale-level content validity index [S-CVI] of individual items = 0.99, universal agreement S-CVI = 0.93, agreement κ ≥ 0.75, and clarity p ≥ 0.8). The focus group participants completed the Playbook in an average (sd) time of 53 (14) minutes, demonstrating significant improvements in pre-post quiz scores (74% vs 86%; p = 0.0009). Verbal feedback highlighted the conciseness, utility, and relevance of the Playbook, with all participants agreeing to deploy the digital education module in their ICUs. CONCLUSIONS: The ICU Delirium Playbook is a novel, first-of-its-kind asynchronous digital education tool aimed to standardize delirium detection and prevention practices. After a rigorous content and face validation process, the Playbook is now available for widespread use.

Synergistic Strategies to Accelerate the Development of Function-Promoting Therapies: Lessons From Operation Warp Speed and Oncology Drug Development.

BACKGROUND: Functional limitations and physical disabilities associated with aging and chronic disease are major concerns for human societies and expeditious development of function-promoting therapies is a public health priority. METHODS: Expert panel discussion. RESULTS: The remarkable success of Operation Warp Speed for the rapid development of COVID-19 vaccines, COVID-19 therapeutics, and of oncology drug development programs over the past decade have taught us that complex public health problems such as the development of function-promoting therapies will require collaboration among many stakeholders, including academic investigators, the National Institutes of Health, professional societies, patients and patient advocacy organizations, the pharmaceutical and biotechnology industry, and the U.S. Food and Drug Administration. CONCLUSIONS: There was agreement that the success of well designed, adequately powered clinical trials will require careful definitions of indication/s, study population, and patient-important endpoints that can be reliably measured using validated instruments, commensurate resource allocation, and versatile organizational structures such as those used in Operation Warp Speed.

Health Communication Research Informs Inflammatory Bowel Disease Practice and Research: A Narrative Review.

Background: In the absence of targeted empirical evidence on effective clinical communication in inflammatory bowel disease (IBD), a broad overview of existing evidence on effective communication in healthcare and available recommendations for communication in telehealth is provided and mapped onto IBD research and practice. Methods: A narrative literature review was conducted using Pubmed and Scopus databases and snowballing literature search. Results: Evidence-based relationship building strategies include communicating emotions, acknowledging and addressing patients' hesitancy, and ensuring continued support. A particular recommendation regarding telehealth interaction is to avoid long stretches of talk. Effective informational strategies include facilitating and supporting information exchange and considering patients' preferences in decision-making. In teleconsultations, clinicians should ask direct questions about patients' emotional state, clarify their understanding of patients' concerns and check patients' understanding, address at least one patient-reported outcome when discussing the recommended treatment, and shorten the consultation where possible. Strategies for maximizing effective clinical communication in the spoken communicative mode include using infographics and simple language, and assessing adherence at the beginning of the consultation. For teleconsultations, clinicians are advised to allow patients to explain the reason for their call at the beginning of the teleconsultation, probe additional concerns early and before ending the teleconsultation, and be mindful of technical issues such as voice delays. Conclusions: Use of question prompt lists, decision aids, micro-lessons, and communication training interventions for clinicians could be beneficial in IBD care. Further research into the implementation of such interventions as well as clinical communication concerns specific to IBD is warranted.

Ultra-low-cost mechanical smartphone attachment for no-calibration blood pressure measurement.

We propose an ultra-low-cost at-home blood pressure monitor that leverages a plastic clip with a spring-loaded mechanism to enable a smartphone with a flash LED and camera to measure blood pressure. Our system, called BPClip, is based on the scientific premise of measuring oscillometry at the fingertip to measure blood pressure. To enable a smartphone to measure the pressure applied to the digital artery, a moveable pinhole projection moves closer to the camera as the user presses down on the clip with increased force. As a user presses on the device with increased force, the spring-loaded mechanism compresses. The size of the pinhole thus encodes the pressure applied to the finger. In conjunction, the brightness fluctuation of the pinhole projection correlates to the arterial pulse amplitude. By capturing the size and brightness of the pinhole projection with the built-in camera, the smartphone can measure a user's blood pressure with only a low-cost, plastic clip and an app. Unlike prior approaches, this system does not require a blood pressure cuff measurement for a user-specific calibration compared to pulse transit time and pulse wave analysis based blood pressure monitoring solutions. Our solution also does not require specialized smartphone models with custom sensors. Our early feasibility finding demonstrates that in a validation study with N = 29 participants with systolic blood pressures ranging from 88 to 157 mmHg, the BPClip system can achieve a mean absolute error of 8.72 and 5.49 for systolic and diastolic blood pressure, respectively. In an estimated cost projection study, we demonstrate that in small-batch manufacturing of 1000 units, the material cost is an estimated $0.80, suggesting that at full-scale production, our proposed BPClip concept can be produced at very low cost compared to existing cuff-based monitors for at-home blood pressure management.

The influences of faith on illness representations and coping procedures of mental and cognitive health among aging Arab refugees: a qualitative study.

Introduction: Refugees experience higher rates of mental illness such as depression and post-traumatic stress disorder (PTSD) which are documented risk factors for dementia. Faith and spiritual practices have been shown to play a significant role in patients' understanding and coping with illness, however, this field of study among refugee populations remains lacking. This study aims to address this literature gap by examining the role of faith on mental health and cognitive health among Arab refugees resettled in Arab and Western countries. Materials and methods: A total of 61 Arab refugees were recruited through ethnic community-based organizations in San Diego, California, United States (N = 29) and Amman, Jordan (N = 32). Participants were interviewed through in-depth, semi-structured interviews or focus groups. Interviews and focus groups were transcribed, translated, and coded using inductive thematic analysis and organized based on Leventhal's Self-Regulation Model. Results: Faith and spiritual practices significantly impact participants' illness perceptions and coping procedures regardless of resettlement country or gender. Several themes emerged: (1) participants believe in the interdependent relationship between mental and cognitive health. (2) There is a self-awareness of the impact of the refugee experience and trauma on participants' mental health problems, leading to a belief of increased personal risk for developing dementia. (3) Spiritual fatalism (belief that events are predetermined by God, fate, or destiny) greatly informs these perceptions of mental and cognitive health. (4) Participants acknowledge that practicing faith improves their mental and cognitive health, and many read scripture to prevent dementia. (5) Finally, spiritual gratitude and trust are important coping procedures that build resilience among participants. Conclusions: Faith and spirituality play an important role in shaping Arab refugees' illness representations and coping procedures of mental and cognitive health. Holistic public health and clinical interventions tailored to the spiritual needs of aging refugees and incorporating religion in prevention strategies are increasingly needed to improve the brain health and wellbeing of refugees.

Ultra-low-cost Mechanical Smartphone Attachment for No-Calibration Blood Pressure Measurement.

We propose BPClip, a less than $ 1 USD blood pressure monitor that leverages a plastic clip with a spring-loaded mechanism to enable any smartphone with a flash LED and a camera to measure blood pressure. Unlike prior approaches, our system measured systolic, mean, and diastolic blood pressure using oscillometric measurements that avoid cumbersome per-user calibrations and does not require specialized smartphone models with custom sensors.
