Amateur Boxing and Dementia: Cognitive Impairment Within the 35-Year Caerphilly Cohort Study.

OBJECTIVE: To examine the long-term effects of amateur boxing in a representative population sample of men. DESIGN: The sample was examined every 5 years for 35 years. Cognition was assessed repeatedly from the third examination. Previous boxing experience and dementia were assessed at the fifth examination, and dementia assessed subsequently through medical records. SETTING AND ASSESSMENT OF RICK FACTORS: The Caerphilly Prospective Study investigates risk factors for a range of chronic diseases of diseases. These include life style and behavior, together with biological factors relevant to vascular disease. PARTICIPANTS: 1123 adult men aged 45 to 59 years at baseline, followed for 35 years. MAIN OUTCOME MEASURES: Cognitive impairment. RESULTS: A report by a subject of having boxed "seriously" when younger was associated with a 2-fold increase in cognitive impairment [odds ratio (OR) = 2.27; 95% confidence intervals = 1.18-4.38]. For amnestic (Alzheimer-like) impairment, this rises to OR = 2.78 (95% confidence limits 1.37-5.65). Having boxed is associated with an "advancement" in the onset of the dementia (4.8 years; 95% confidence limits 0.9-8.8 years). CONCLUSIONS: Amateur boxing is associated with an increased risk and an earlier onset of cognitive impairment and dementia.

Cross-sectional survey study to examine underuse of twice daily inhaled maintenance therapy among patients with asthma.

Objective: Anecdotal evidence suggests that some patients with asthma intentionally use their twice-daily (BID) inhaled controller therapy once daily (QD), thus not achieving optimal dosing levels. This study identified the prevalence of and factors associated with intentional QD use of BID-indicated controllers among adult patients with asthma. Methods: This was a cross-sectional survey study of adults using inhaled controllers intended for BID dosing for treatment of asthma and/or COPD. Survey responses were linked to administrative claims data for the prior 12 months (baseline). Results of patients indicating both an asthma diagnosis and current intentional QD or BID use of controllers are presented. Results: Of 1401 patients with asthma, 30.9% reported intentional QD use of their controller and 69.1% reported BID use. Intentional QD use was mostly a function of patients' lack of perceived need for BID treatment (44.1%) or physician orders to take their controller QD (34.0%). Patients reporting intentional QD use tended to be healthier (higher health status scores, and lower Charlson comorbidity scores, ambulatory and ER visits, and healthcare costs) with better asthma control (lower asthma-related ER and ambulatory visits and rescue medication use, and higher Asthma Control Test scores) compared with patients reporting BID use. Conclusions: Perceptions regarding health and the necessity of controller use to control or treat asthma were the main drivers of medication-taking behavior. Patients with less severe asthma were more likely to report once daily use of their inhaled controller, but still maintained asthma control.

Talking to the people that really matter about their participation in pandemic clinical research: A qualitative study in four European countries.

BACKGROUND: Pandemics of new and emerging infectious diseases are unpredictable, recurrent events that rapidly threaten global health and security. We aimed to identify public views regarding provision of information and consent to participate in primary and critical care clinical research during a future influenza-like illness pandemic. METHODS: Descriptive-interpretive qualitative study, using focus groups (n = 10) and semi-structured interviews (n = 16), with 80 members of the public (>18 years) in Belgium, Spain, Poland and the UK. Local qualitative researchers followed a scenario-based topic guide to collect data. Data were transcribed verbatim, translated into English and subject to framework analysis. RESULTS: Public understandings of pandemics were shaped by personal factors (illness during the previous H1N1 pandemic, experience of life-threatening illness) and social factors (historical references, media, public health information). Informants appreciated safeguards provided by ethically robust research procedures, but current enrolment procedures were seen as a barrier. They proposed simplified enrolment processes for higher risk research and consent waiver for certain types of low-risk research. Decision making about research participation was influenced by contextual, research and personal factors. Informants generally either carefully weighed up various approaches to research participation or responded instinctively. They supported the principle of using routinely collected, anonymized clinical biological samples for research without explicit consent, but regarded this as less acceptable if researchers were motivated primarily by commercial gain. CONCLUSIONS: This bottom-up approach to ascertaining public views on pandemic clinical research has identified support for more proportionate research protection procedures for publically funded, low-risk studies.

Impact of a National Cancer Prevention and Treatment Program on the Prevalence of Late-Stage Breast Cancer Diagnoses in Oklahoma.

In 2000, Congress passed the Breast and Cervical Cancer Prevention and Treatment Act (BCCPTA) to provide coverage through Medicaid to women who screened positive for breast and cervical cancer. We aimed to determine if late-stage breast cancer prevalence decreased among Oklahoma women after passage of BCCPTA. Data were obtained from the Oklahoma Central Cancer Registry during 2000-2011. We estimated prevalence proportion ratios (PPR) using modified Poisson regression between the proportion of women with late-stage breast cancer and timing of diagnosis related to BCCPTA. Among uninsured women, the probability of being diagnosed with late-stage cancer after enactment of the BCCPTA was 0.80 (95% CI: 0.67, 0.96) times the probability before enactment. This was significant among uninsured women living in metro counties (PPR: 0.74, 95% CI: 0.61, 0.90) but not in non-metro counties (PPR: 1.05, 95% CI: 0.71, 1.56). These findings may be similar to other rural states with large uninsured populations.

Discrete choice experiment to estimate breast cancer patients' preferences and willingness to pay for prophylactic granulocyte colony-stimulating factors.

OBJECTIVES: Rising out-of-pocket costs for cancer patients have increased shared decision making. Clinical guidelines recommend prophylactic granulocyte colony-stimulating factor (G-CSF) for patients receiving chemotherapy with a 20% or greater risk of febrile neutropenia. A discrete choice experiment was conducted to explore breast cancer patients' preferences and willingness to pay (WTP) for prophylactic G-CSF to decrease the risk of chemotherapy-induced febrile neutropenia. METHODS: An online discrete choice experiment questionnaire survey of a national US convenience sample of self-reported breast cancer patients with prior chemotherapy treatment was conducted. Sixteen paired G-CSF treatment scenarios, each with four attributes (risk of disruption to chemotherapy schedule due to low white blood cell counts, risk of developing an infection requiring hospitalization, frequency of administration, and total out-of-pocket cost) were presented with a follow-up "no treatment" option. Participant preferences and WTP out of pocket were estimated by logistic regression. RESULTS: Participants (n = 296) preferred G-CSF regimens with lower out-of-pocket costs, lower risk of chemotherapy disruption, lower risk of infection, and greater convenience (one G-CSF injection per chemotherapy cycle). Participants' WTP was $1076 out of pocket per cycle to reduce the risk (high to low) of disrupting their chemotherapy schedule, $884 per cycle to reduce the risk (24% [high] to 7% [low]) of infection, and $851 per cycle to decrease the number of G-CSF injections (11 to 1) per cycle. CONCLUSIONS: Participants highly valued specific features of prophylactic G-CSF treatment including maintaining their chemotherapy schedule, lowering their risk of infection, and reducing the number of injections. Physicians should consider patient preferences to inform the best treatment choices for individual patients.

Informing evidence-based policy during the COVID-19 pandemic and recovery period: learning from a national evidence centre.

BACKGROUND: The COVID-19 pandemic demonstrated the vital need for research to inform policy decision-making and save lives. The Wales COVID-19 Evidence Centre (WCEC) was established in March 2021 and funded for two years, to make evidence about the impact of the pandemic and ongoing research priorities for Wales available and actionable to policy decision-makers, service leads and the public. OBJECTIVES: We describe the approaches we developed and our experiences, challenges and future vision. PROGRAM IMPLEMENTATION: The centre operated with a core team, including a public partnership group, and six experienced research groups as collaborating partners. Our rapid evidence delivery process had five stages: 1. Stakeholder engagement (continued throughout all stages); 2. Research question prioritisation; 3. Bespoke rapid evidence review methodology in a phased approach; 4. Rapid primary research; and 5. Knowledge Mobilisation to ensure the evidence was available for decision-makers. MAIN ACHIEVEMENTS: Between March 2021-23 we engaged with 44 stakeholder groups, completed 35 Rapid Evidence Reviews, six Rapid Evidence Maps and 10 Rapid Evidence Summaries. We completed four primary research studies, with three published in peer reviewed journals, and seven ongoing. Our evidence informed policy decision-making and was cited in 19 Welsh Government papers. These included pandemic infection control measures, the Action Plan to tackle gender inequalities, and Education Renew and Reform policy. We conducted 24 Welsh Government evidence briefings and three public facing symposia. POLICY IMPLICATIONS: Strong engagement with stakeholder groups, a phased rapid evidence review approach, and primary research to address key gaps in current knowledge enabled high-quality efficient, evidence outputs to be delivered to help inform Welsh policy decision-making during the pandemic. We learn from these processes to continue to deliver evidence from March 2023 as the Health and Care Research Wales Evidence Centre, with a broader remit of health and social care, to help inform policy and practice decisions during the recovery phase and beyond.

Protocol for a feasibility study of a cancer symptom awareness campaign to support the rapid diagnostic centre referral pathway in a socioeconomically deprived area: Targeted Intensive Community-based campaign To Optimise Cancer awareness (TIC-TOC).

INTRODUCTION: Rapid diagnostic centres (RDCs) are being implemented across the UK to accelerate the assessment of vague suspected cancer symptoms. Targeted behavioural interventions are needed to augment RDCs that serve socioeconomically deprived populations who are disproportionately affected by cancer, have lower cancer symptom awareness and are less likely to seek help for cancer symptoms. The aim of this study is to assess the feasibility and acceptability of delivering and evaluating a community-based vague cancer symptom awareness intervention in an area of high socioeconomic deprivation. METHODS AND ANALYSIS: Intervention materials and messages were coproduced with local stakeholders in Cwm Taf Morgannwg, Wales. Cancer champions will be trained to deliver intervention messages and distribute intervention materials using broadcast media (eg, local radio), printed media (eg, branded pharmacy bags, posters, leaflets), social media (eg, Facebook) and attending local community events. A cross-sectional questionnaire will include self-reported patient interval (time between noticing symptoms to contacting the general practitioner), cancer symptom recognition, cancer beliefs and barriers to presentation, awareness of campaign messages, healthcare resource use, generic quality of life and individual and area-level deprivation indicators. Consent rates and proportion of missing data for patient questionnaires (n=189) attending RDCs will be measured. Qualitative interviews and focus groups will assess intervention acceptability and barriers/facilitators to delivery. ETHICS AND DISSEMINATION: Ethical approval for this study was given by the London-West London & GTAC Research Ethics (21/LO/0402). This project will inform a potential future controlled study to assess intervention effectiveness in reducing the patient interval for vague cancer symptoms. The results will be critical to informing national policy and practice regarding behavioural interventions to support RDCs in highly deprived populations.

Epidemiology and course of disease in childhood uveitis.

PURPOSE: To describe the disease characteristics and visual outcome of pediatric uveitis. DESIGN: Retrospective, longitudinal observation. PARTICIPANTS: Five hundred twenty-seven pediatric uveitis patients from the National Eye Institute, University of Illinois, Chicago, and Oregon Health Sciences University. METHODS: Retrospective chart review. MAIN OUTCOME MEASURES: Demographics, uveitis disease characteristics, complications, treatments, and visual outcomes were determined at baseline and at 1-, 3-, 5-, and 10-year time points. RESULTS: The patient population was 54% female; 62.4% white, 12.5% black, 2.7% Asian, 2.1% multiracial, and 14.61% Hispanic. Median age at diagnosis was 9.4 years. The leading diagnoses were idiopathic uveitis (28.8%), juvenile idiopathic arthritis-associated uveitis (20.9%), and pars planitis (17.1%). Insidious onset (58%) and persistent duration (75.3%) were most common. Anterior uveitis was predominant (44.6%). Complications were frequent, and cystoid macular edema (odds ratio [OR] 2.94; P = 0.006) and hypotony (OR, 4.54; P = 0.026) had the most significant visual impact. Ocular surgery was performed in 18.9% of patients. The prevalence of legal blindness was 9.23% at baseline, 6.52% at 1 year, 3.17% at 3 years, 15.15% at 5 years, and 7.69% at 10 years. Posterior uveitis and panuveitis had more severe vision loss. Hispanic ethnicity was associated with a higher prevalence of infectious uveitis and vision loss at baseline. CONCLUSIONS: The rate and spectrum of vision threatening complications of pediatric uveitis are significant. Prospective studies using standard outcome measures and including diverse populations are needed to identify children most at risk.

Priority Needs for Conducting Pandemic-relevant Clinical Research With Children in Europe: A Consensus Study With Pediatric Clinician-researchers.

BACKGROUND: Infectious disease (ID) pandemics pose a considerable global threat and can disproportionately affect vulnerable populations including children. Pediatric clinical research in pandemics is essential to improve children's healthcare and minimize risks of harm by interventions that lack an adequate evidence base for this population. The unique features of ID pandemics require consideration of special processes to facilitate clinical research. We aimed to obtain consensus on pediatric clinician-researchers' perceptions of the priorities to feasibly conduct clinical pediatric pandemic research in Europe. METHODS: Mixed method study in 2 stages, recruiting pediatric clinician-researchers with experience of conducting pediatric ID research in clinical settings in Europe. Stage 1 was an expert stakeholder workshop and interviews. Discussions focused on participant's experience of conducting pediatric ID research and processes to facilitate pandemic research. Information informed stage 2, an online consensus survey to identify pediatric inician-researchers priorities to enable ID pandemic research. RESULTS: Twenty-three pediatric clinician-researchers attended the workshop and 39 completed the survey. Priorities were primarily focused on structural and operational requirements of research design and regulation: (1) clarity within the European Clinical Trials Directive for pediatric pandemic research; (2) simplified regulatory processes for research involving clinical samples and data; and (3) improved relationships between regulatory bodies and researchers. CONCLUSIONS: Results suggest that changes need to be made to the current regulatory environment to facilitate and improve pediatric research in the pandemic context. These findings can provide expert evidence to research policy decision-makers and regulators and to develop a strategy to lobby for change.

Matching diagnostics development to clinical need: Target product profile development for a point of care test for community-acquired lower respiratory tract infection.

BACKGROUND: Point of care tests (POCTs) are increasingly being promoted for guiding the primary medical care of community acquired lower respiratory tract infections (CA-LRTI). POCT development has seldom been guided by explicitly identified clinical need and requirements of the intended users. Approaches for identifying POCT priorities and developing target product profiles (TPPs) for POCTs in primary medical care are not well developed, and there is no published TPP for a CA-LRTI POCT aimed at developed countries. METHODS: We conducted workshops with expert stakeholders and a survey with primary care clinicians to produce a target product profile (TPP) to guide the development of a clinically relevant and technologically feasible POCT for CA-LRTI. RESULTS: Participants with clinical, academic, industrial, technological and basic scientific backgrounds contributed to four expert workshops, and 45 practicing primary care clinicians responded to an online survey and prioritised community-acquired pneumonia (CAP) as the CA-LRTI where a new POCT was most urgently needed. Consensus was reached on a TPP document that included information on the intended niche in the clinical pathway in primary medical care; diagnostic product specification (intended use statement and test concept), and minimum and ideal user specifications. Clinicians minimum requirements of a CA-LRTI POCT included the use of minimally invasive samples, a result in less than 30 minutes, no more than a single preparation step, minimum operational requirements, and detection of common respiratory pathogens and their resistance to commonly prescribed antibiotics. CONCLUSIONS: This multidisciplinary, multistage partnership approach generated a clinically-driven TPP for guiding the development of a new POCT, and this approach as well as the TPP itself may be useful to others developing a new POCT.
