Purpose: Medical students are at increased risk of poor mental health and need to regularly engage in preventive programs to maintain well-being. However, many do not and it remains an open question whether these programs should be mandatory. We implemented a RCT to examine the effectiveness of assigning medical students to a wellness intervention on adherence to engagement in the assigned intervention and on psychological and academic outcomes. Method: Medical students participated in a 12-week randomized controlled intervention involving one-hour wellness sessions of either (1) yoga; (2) mindfulness; or (3) walking, held twice-weekly. Students completed standardized psychological assessments at baseline and following the intervention. Results: Students randomized to the wellness intervention group engaged in more minutes of assigned activities than students randomized to the control. There was a significant difference in the change from pre-to post-intervention on measures of state anxiety and perceived stress, with better outcomes for the intervention group. Conclusions: The assignment of twice-weekly wellness intervention sessions protects medical students from state anxiety and perceived stress with no negative impact on academic performance. Students adhered to the sessions and reported enjoying the sessions once trying them. Actual engagement is more important than wellness activity type.

Vertebral artery stenosis (VAS) is the cause of approximately 20% of ischemic strokes in the posterior circulation. There are several causes of vertebral artery stenosis, including atherosclerosis, calcification, dissections, fibromuscular dysplasia, giant cell arteritis, neurofibromatosis type 1, and bony compressions. The most common cause of VAS is atherosclerosis which is derived from the macrophage-induced oxidation of low-density lipoproteins (LDLs), alongside the accumulation of cholesterol. Calcification of the vertebral artery occurs when there is excess calcium and phosphate deposition in the vessel. Dissection of the vertebral artery can lead to the formation of a hematoma causing stenosis of the vertebral artery. Fibromuscular dysplasia can result in stenosis due to the deposition of collagen fibers in the tunica media, intima, or adventitia. Giant cell arteritis, an autoimmune disorder, causes inflammation of the internal elastic membrane resulting in eventual stenosis of the artery. Neurofibromatosis type 1, an autosomal dominant disorder, results in the stenosis of the vertebral artery due to the altered function of neurofibromin. Mechanical compression of the vertebral artery by bone can also cause stenosis of the vertebral artery. Digital subtraction angiography (DSA) is considered the current gold standard in diagnosing vertebral artery stenosis; however, its associated morbidity and mortality have led to increased use of noninvasive techniques such as duplex ultrasonography (DUS), computed tomography angiography (CTA), and magnetic resonance angiography (MRA). Currently, asymptomatic and symptomatic vertebral artery stenoses are treated by risk factor modification and medical treatment. However, it is recommended that surgical (endarterectomy, reconstruction, and decompression) and endovascular (balloon coronary, baremetal, and drug-eluting stents) treatments are also used for symptomatic vertebral artery stenosis.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra of the midbrain and basal ganglia, followed by dopamine deficiency in the brain. Dopamine plays a crucial role in motor coordination, memory, and cognition; its decrease in PD leads to dyskinesia, cognitive deficits, and depression. In addition, the formation of alpha-synuclein protein aggregates (Lewy bodies) causes further damage to the CNS. Current treatment options include dopamine precursors, inhibitors of dopamine metabolism, upregulation of autophagy, adenosine A2A antagonists, and surgical intervention as a last resort. A challenge arises from a progressive decrease in treatment efficacy as the disease progresses and this necessitates exploration of adjunctive treatments. Epidemiological studies suggest that the prevalence of PD varies between ethnic groups of Caucasians, Asians, and African Americans. Notably, the prevalence of PD is lower in countries of Southeastern Asia including India. The differences in the diet of various ethnic groups may suggest an origin for this difference in the prevalence of PD. One staple ingredient in traditional Asian cuisine is turmeric. Curcuma longa , popularly known as turmeric, is an orange tuberous rhizome that has been used for centuries in traditional Indian cuisine and traditional medicine. Turmeric contains curcumin, a potent antioxidant that scavenges reactive oxygen species and chelates toxic metals. Curcumin has been proposed to be a neuroprotective agent due to its potent antioxidative properties. Though preliminary studies in animal model systems have suggested a protective effect of curcumin on dopaminergic neurons, the direct benefits of curcumin on the progress of PD remains poorly understood. In this review, we explore the promising use of curcumin as an adjunct to conventional PD treatments in order to enhance treatment and improve outcomes.

This article explores the value of hosting a grassroots neuroscience workshop that facilitates near-peer engagement between year-one medical students and local Brain Bee finalists (high school students). Nearpeer mentoring is a formal relationship in which more academically advanced students guide immediate junior students. We hypothesized that similar activities have teaching, learning, and psychosocial benefits for all and can be easily replicated. ActivityThe Grenada National Brain Bee Challenge was launched in 2009 as a competition for high school students. Annually, there are at least 100 high school students registering to participate in the national challenge. In 2018, a grassroots neuroscience symposium, a local initiative, was created to prepare high school students who participated in the preliminary rounds for the final local and International Brain Bee competition. Traditionally, it is hosted annually by faculty at St. George's University School of Medicine (SOM). However, in 2022, the symposium was hosted by medical students. The symposium is designed as an eight-hour tutorial one-day session. The students rotate between facilitators as small group teams during each teaching hour. There are icebreakers, content presentations, and neuroanatomy skills stations. The medical students demonstrate expertise in neuroscience content and other aspects of professional competence. The activity was also designed to offer students of diversified backgrounds the opportunity to affect their educational pathways through role modeling, mirroring, and mentorship. Was this change beneficial to both sets of students (medical and high school)? Results and discussionWe aim to determine the value of the near-peer relationship between the local 2022 Brain Bee finalists (high school students) (n=28) and university (medical) students (n=11). Participants were surveyed about their experience. Data were de-identified and grouped according to common themes. A thematic analysis was conducted on the data retrieved from the literature review. Data suggest that both high school and university (medical) students report benefits after participating in near-peer engagement at a grassroots neuroscience symposium. In this teaching model, the medical students are the more experienced instructors and transfer their knowledge and skills about the field to the high school students. The medical students have an opportunity to consolidate their personal learning and give back to the Grenadian community. While informal teaching occurs often, this type of near-peer engagement with students from the community helps medical students develop both personal and professional skills such as confidence, knowledge, and respect. This grassroots initiative is easily replicated in a medical curriculum. The major benefits experienced by the high school student participants (of various socioeconomic backgrounds) were access to educational resources. The symposium requires active engagement, fosters a sense of belonging, and promotes interest in pursuing caree...
