Prospective Evaluation of Atrial Fibrillation-Related Stroke Patients in Rehabilitation Program (PEARL), an Observational Cohort Study

The goal of this observational study is to determine if rehabilitation program intensity impacts functional recovery and specific needs in adult ischemic stroke patients who require inpatient rehabilitation. The main questions it aims to answer are: Do patients with stroke of Atrial-related subtypes (AFRS) have distinct rehabilitation needs and functional outcomes compared to non-AFRS patients? Does higher-intensity inpatient rehabilitation (3-5 sessions/day) result in better functional recovery at six months (measured by the Barthel Index) than moderate-intensity programs (1 session/day)? The study is non-invasive, does not interfere with usual care. The investigators' ultimate goal is to enhance the understanding of recovery after following different rehabilitation usual programs.

Cardiac point-of Care Ultrasound Training Pathway for Emergency Department Advanced Practice Providers

The aim of this study is to assess emergency medicine physician and advanced practice provider (APP) knowledge and technical skill in performance of a point-of-care ultrasound simulation and just-in-time training pathway to determine the feasibility, acceptability, and usability of the ultrasound training program. By performing this study, we hope to create a standardized training model which could potentially facilitate point-of-care ultrasound (POCUS) clinical performance and thereby improve patient care.

Truway Diagnostic Tools in Primary Care

This study evaluates the effectiveness of Truway Health-sourced portable diagnostic devices, including ultrasound and blood glucose monitors, in early detection of chronic conditions in outpatient primary care settings. Conducted as a prospective interventional trial, 200 participants will be assigned to use these devices versus standard care over a 6-month period. The primary outcome is improved diagnostic accuracy and patient outcomes. The study, led by Truway Health, Inc., aims to enhance accessible healthcare solutions starting at a New York site, with potential expansion to Miami.

Cardiovascular Health of Transgender Individuals During the Gender-affirming Pathway

Gender incongruence, now classified in ICD-11 as a "marked and persistent incongruence between an individual's experienced gender and the gender assigned at birth," is managed in dedicated, multidisciplinary centres that coordinate psychological support with medical-surgical care. Gender-affirming hormone therapy (GAHT) is central to this care pathway. In particular, masculinising GAHT for people assigned female at birth (AFAB) relies mainly on testosterone, and feminising or demasculinising GAHT for people assigned male at birth (AMAB) combines oestradiol with androgen-lowering agents such as cyproterone acetate or GnRH analogues (triptorelin, leuprorelin). In addition, Gender-affirming surgery (GAS) offers further individualised options: "Top" procedures- chest masculinisation for AFAB or breast augmentation for AMAB, and "Bottom" procedures\*\* such as hysterectomy with or without oophorectomy, phalloplasty or metoidioplasty for AFAB; orchiectomy or vaginoplasty for AMAB. Other ancillary interventions include facial feminisation or voice surgery. GAHT aims to suppress endogenous sex-hormone levels and secondary sex characteristics while inducing those consistent with the affirmed gender. Despite its widespread use, cardiovascular (CV) safety data are scant and largely observational. Sex-steroid receptors are ubiquitous in the vasculature and contribute to the sex-dimorphic patterns of CV risk seen in cisgender populations; GAHT is therefore biologically plausible as a modifier of CV outcomes in transgender people, yet robust evidence remains limited. Current literature suggests that AFAB individuals on testosterone exhibit an up to 2.66-fold higher composite CV risk than cisgender AFAB comparators. The most consistent changes are higher blood pressure and lower HDL cholesterol; clinically significant polycythaemia is uncommon and treatable. Instead, AMAB individuals on feminising therapy do not show a clearly increased overall CV risk compared with cisgender AMAB peers, though data are inconsistent. An observational study reported that within four months of GAHT initiation, systolic blood pressure rose by 2.6 mmHg in trans men and fell by 4 mmHg in trans women, with no diastolic change in either group. The current evidence base is weakened by small cohorts, inadequate control groups, and reliance on surrogate biochemical markers rather than hard clinical endpoints. Many studies also overlook GAHT exposure altogether, hampering meaningful interpretation. Moreover, social determinants-mental-health burden, substance use, and healthcare inequities-compound CV risk but are seldom accounted for. Key unanswered questions include the long-term CV effects of GAHT, age-specific interactions with blood pressure and lipids, optimal therapeutic targets, and underlying mechanisms. Addressing these gaps demands rigorously designed, large-scale, prospective studies that actively involve transgender participants. In summary, while GAHT is indispensable for gender affirmation, its cardiovascular implications-especially for AFAB individuals-warrant caution and systematic monitoring. Future evidence should inform tailored protocols that balance gender-affirming benefits against potential CV risks and integrate biomedical parameters with the broader social context impacting transgender health.
