Background: Linkage to and retention in HIV care are challenging, especially in the Southeastern United States. The rise in mobile phone app use and the potential for an app to deliver just in time messaging provides a new opportunity to improve linkage and retention among people living with HIV (PLWH).
Objective: This study aimed to develop an app to engage, link, and retain people in care. We evaluated the acceptability, feasibility, and impact of the app among users.
Methods: App development was informed by principles of chronic disease self-management and formative interviews with PLWH. Once developed, the app was distributed among participants, and usability feedback was incorporated in subsequent iterations. We interviewed app users after 3 weeks to identify usability issues, need for training on the phone or app, and to assess acceptability. We tracked and analyzed usage of app features for the cohort over 2 years.
Results: A total of 77 participants used the app during the pilot study. The query response rate for the first 2 years was 47.7%. Query response declined at a rate of 0.67% per month. The community message board was the most popular feature, and 77.9% (60/77) of users posted on the board at least once during the 2 years.
Conclusions: The PositiveLinks app was feasible and acceptable among nonurban PLWH. High participation on the community message board suggests that social support from peers is important for people recently diagnosed with or returning to care for HIV.

Introduction: The ubiquity of Bring Your Own Device (BYOD) personal smartphones, Instant Messaging (IM), and third-party apps, has made these technologies compelling for efficient communications between clinicians regarding patient care. However, the sensitivity of patient-related information necessitates secure, GDPR compliant modalities that prevent unauthorised access and ensure confidentiality. This scoping review explores existing guidelines, policies, and regulations that advise clinicians in the UK and Ireland on the secure use of these digital communication tools.

Objective: The benefits of mobile applications in the prenatal period remain understudied. This study assessed associations between the Pregnancy Postpartum Support Program (PPSP), a digital wraparound service, and maternal and infant outcomes in a Medicaid population.
Methods: A retrospective analysis was conducted on pregnant patients with Medicaid insurance who received care and delivered in a Midwestern United States healthcare system between 8/1/2022-8/15/2023, comparing outcomes among those who did versus did not opt for PPSP enrollment.
Modulation of mitochondrial functions contributes to the protection of lamotrigine against Alzheimer's disease.

Background: Our previous studies have established that the broad-spectrum anti-epileptic drug lamotrigine (LTG) confers protection against cognitive impairments, synapse and nerve cell damage, as well as characteristic neuropathologies in APP/PS1 mice, a mouse model of Alzheimer's disease (AD). However, the precise molecular mechanisms responsible for this protective effect induced by LTG remain largely elusive.
Objective: In this study, we aimed to investigate the mechanisms underlying the beneficial effects of LTG against AD.

Background: Using long-acting injectable (LAI) antipsychotics is crucial for treating psychiatric illnesses, particularly those within the schizophrenia spectrum. Through bibliometric analysis, our study aimed to provide an understanding of the changes in research trends related to LAIs over the past 40 years.
Methods: We collected the publications from 1983 to 2023 related to research studies on LAIs included in the Web of Science database.
Evaluating the Safety and Usability of an Over-the-Counter Medical Device for Adults With Mild to Moderate Hearing Loss: Formative and Summative Usability Testing.

Background: Only 15% of the nearly 30 million Americans with hearing loss use hearing aids, partly due to high cost, stigma, and limited access to professional hearing care. Hearing impairment in adults can lead to social isolation and depression and is associated with an increased risk of falls. Given the persistent barriers to hearing aid use, the Food and Drug Administration issued a final rule to allow over-the-counter hearing aids to be sold directly to adult consumers with perceived mild to moderate hearing loss at pharmacies, stores, and online retailers without seeing a physician or licensed hearing health care professional.
