Youth experiencing homelessness are more likely than housed youth to experience premature death, suicide, drug overdose, pregnancy, substance use, and mental illness. Yet while youth experiencing homelessness are 6 to 12 times more likely to become infected with HIV than housed youth, with HIV prevalence as high as 16%, many do not access the prevention services they need. Despite adversities, youth experiencing homelessness are interested in health promotion programs, can be recruited and retained in interventions and research studies, and demonstrate improved outcomes when programs are tailored and relevant to them. The study aims to compare the efficacy of a nurse case management HIV prevention and care intervention, titled Come As You Are, with that of usual care among youth experiencing homelessness aged 16 to 25 years. The study is designed as a 2-armed randomized wait-list controlled trial. Participants (n=450) will be recruited and followed up for 9 months after the intervention for a total studersonalized and mobile HIV prevention approach can reduce HIV risk among a hard-to-reach, transient population of youth at high risk.

It is argued that developing more sensitive, easy to administer, and valid MCI screening tools for use in primary care settings may initiate timely clinical and personal care planning and treatment, enabling early access to programs and services. Including functional competence measures in screening tests makes them more ecologically valid and may help to identify cognitive deficits at an earlier stage. We aim to conduct a preliminary evaluative study comparing the sensitivity, specificity, and reliability of the BrainFx Screen (referred to as SCREEN hereafter), a novel digital tool designed to assess functional competence and detect early signs of cognitive impairment, with the Quick Mild Cognitive Impairment, a validated and highly sensitive tool that detects MCI in the older adult population. We will also investigate the perceived usefulness and integrat. Sickle cell anemia (SCA) is a genetic blood disorder that puts children at a risk of serious medical complications, early morbidity and mortality, and high health care utilization. Until recently, hydroxyurea was the only disease-modifying treatment for this life-threatening disease and has remained the only option for children younger than 5 years. Evidence-based guidelines recommend using a shared decision-making (SDM) approach for offering hydroxyurea to children with SCA (HbSS or HbS/β0 thalassemia) aged as early as 9 months. https://www.selleckchem.com/products/Cyclosporin-A(Cyclosporine-A).html However, the uptake remains suboptimal, likely because caregivers lack information about hydroxyurea and have concerns about its safety and potential long-term side effects. Moreover, clinicians do not routinely receive training or tools, especially those that provide medical evidence and consider caregivers' preferences and values, to facilitate a shared discussion with caregivers. The aim of this study is to understand how best to help parents of young children with sickle cellality care, caregivers of patients with SCA can make informed and shared decisions about their health.

Given the increasing number of people in need of palliative care services and the current health care professional workforce strain, providing equitable, quality palliative care has become a challenge. Telehealth could be an innovative approach to palliative care delivery, enabling patients to spend more time or even remain at home, if they wish, throughout the illness trajectory. However, no previous systematic mixed studies reviews have synthesized evidence on patients' experiences of the advantages and challenges of telehealth for home-based palliative care. The aim of this systematic mixed studies review is to critically appraise and synthesize findings from studies that investigated patients' use of telehealth in home-based palliative care with a focus on the advantages and challenges experienced by the patients. This article describes the protocol for a systematic mixed studies review with a convergent design. The reporting will be guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. A systematic search was performed in eight databases for studies published from January 2010 to June 2020. The search will be updated in 2021. Pairs of authors will independently assess eligibility, extract data, and assess methodological quality. The data will then be analyzed using thematic synthesis. We describe the rationale and design of a systematic mixed studies review. The database searches were performed on June 25, 2020. Assessment of eligibility and further steps have not yet been performed. Results are anticipated by August 2021. Following the ethos of patient-centered palliative care, this systematic mixed studies review could lead to recommendations for practice and policy, enabling the development and implementation of telehealth applications and services that align with patients' preferences and needs at home.

Crowding can potentially be eased through streamlining and the reduction of duplication in patient history-taking through the use of a digital symptom-taking app. We simulated the introduction of a digital symptom-taking app on patient flow. We hypothesized that waiting times and crowding in an urgent care center (UCC) could be reduced, and that this would be more efficient than simply adding more staff. A discrete-event approach was used to simulate patient flow in a UCC during a 4-hour time frame. The baseline scenario was a small UCC with 2 triage nurses, 2 doctors, 1 treatment/examination nurse, and 1 discharge administrator in service. We simulated 33 scenarios with different staff numbers or different potential time savings through the app. We explored average queue length, waiting time, idle time, and staff utilization for each scenario. Discrete-event simulation showed that even a few minutes saved through patient app-based self-history recording during triage could result in significantly increased efficiency.
