Background:
Deep brain stimulation (DBS) has emerged as a transformative intervention for motor symptom control in patients with Parkinson’s disease (PD). While its benefits are well-established, concerns persist regarding the potential exacerbation or emergence of psychiatric conditions—particularly depression, psychosis, and disinhibition—following DBS. Clarifying these risks is essential for comprehensive patient counseling and long-term management planning.
Methods:
Using the TriNetX Global Collaborative Network, we conducted a retrospective cohort study comparing psychiatric outcomes in PD patients with and without dystonia or tremor who underwent DBS. After 1:1 propensity score matching on demographics and baseline characteristics, each group included 10,200 patients. Psychiatric outcomes were assessed using risk ratios, Kaplan-Meier survival analysis, and Cox proportional hazards models.
Results:
Depression was the most prevalent psychiatric outcome, affecting approximately 24% of both groups. While risk ratios and survival curves showed no significant differences (RR: 0.98; HR: 1.08; p &gt; 0.7), the dystonia/tremor (D/T) group exhibited a trend toward a higher frequency of recurrent depressive episodes (mean: 2.2 vs. 1.1; p = 0.09), although this difference was not statistically significant. Other outcomes—including disinhibition (2.3% vs. 2.1%), delirium (6.5% vs. 5.4%), euphoria (1.3% both), and psychosis (2.3% vs. 2.7%)—were rare and showed no meaningful differences in risk, frequency, or time to onset (all p &gt; 0.3). Overall, Kaplan-Meier curves demonstrated no accelerated onset of psychiatric symptoms in the D/T group.
Conclusion:
In the setting of DBS in PD, these findings indicate that dystonia or tremor does not significantly alter psychiatric risk following DBS in PD. However, ongoing surveillance for depression is warranted as part of post-operative care.

Background
Aggression—defined as the intentional behavior of causing harm to oneself or others—is a symptom of various psychiatric and neurological disorders. It significantly reduces quality of life and is often resistant to standard therapies, sometimes requiring ethically complex interventions. Neuroimaging has linked regions such as the prefrontal cortex, amygdala, and hypothalamus to aggression regulation.
Deep brain stimulation (DBS), a neurosurgical technique using implanted electrodes to modulate neural activity, has shown potential for treating refractory aggression. While established for conditions like Parkinson’s and OCD, its role in managing aggression remains under-explored. This review evaluates the feasibility and outcomes of DBS for aggression.

Methods
This systematic review followed PRISMA-ScR guidelines. We searched Embase, MEDLINE, and Web of Science from inception to June 4, 2023, using terms related to “aggression” and “DBS.” After duplicate removal, six reviewers screened titles and abstracts in Covidence; full-text review and conflict resolution involved additional reviewers. Inclusion criteria were English-language original studies or case reports using DBS to treat aggression with reported outcomes. Non-human studies, reviews, and non-DBS interventions were excluded. Extracted data included demographics, DBS parameters, outcomes, and study characteristics. Risk of bias was assessed using QUIPS for original studies and the JBI checklist for case reports. The primary outcome measured changes in aggressive behavior following DBS.

Results
After screening 1905 papers, 37 studies, from December 1970 to May 2023, consisting of 976 patients (586 males, 319 females, and 71 unspecified), across 12 countries, were included in the final analysis, of which 882 were adults. The mean age of all participants was 55.3 years. The mean follow-up length was 32.26 months (SD 36.29, range 3-144). At least 799 patients (81.66%) were receiving medication prior to surgery. The most common indication for DBS was movement disorders in 232 patients (23.77%), followed by aggression for 200 individuals (20.49%). The subthalamic nucleus was the most common neuroanatomical target site for 744 patients (76.2%), followed by the hypothalamus in 162 patients (16.6%). The Overt Aggression Scale (AOS) was the most frequently used tool for obtaining aggression scores across 9 studies. Improvements in aggression were observed in 144 patients.

Conclusion
Deep brain stimulation shows promise as a safe and viable surgical treatment in reducing aggression across a range of populations, particularly when targeting regions like the hypothalamus and nucleus accumbens. However, future large-scale studies, ideally with long-term follow-ups and unified aggression scale measurements from diverse patient demographics, are required to validate and extend these findings. 


Deep Brain Stimulation in Aggression: A Systematic Review

Background:
Major aortopulmonary collateral arteries (MAPCA) are rare congenital vessels arising from the aorta that supply pulmonary circulation, typically as a response to reduced native pulmonary blood flow. These vessels often present in association with complex congenital heart disease (CHD), prematurity, low birth weight, or chronic lung disease. They commonly provide redundant perfusion to lung lobes, supplementing the pulmonary circulation. This case, however, demonstrates a MAPCA presentation without these common associations nor additional pulmonary circulation.

Case Presentation:
Our patient was born at term with benign prenatal history and delivery. The maternal history was also unremarkable. In the following months, the patient experienced multiple non-specific dermatologic issues and viral-related upper respiratory infections (URI). A heart murmur was first heard at 6 months. In response to the murmur, in conjunction with a history of poor growth, a pediatric cardiology referral was made. Initial evaluation with electrocardiogram and transthoracic echocardiography showed secondary left-sided chamber dilation and pulmonary venous flow turbulence, which raised concern for a possible collateral vessel. Additional cardiac computed tomography angiography (CTA) imaging was obtained, revealing a solitary MAPCA supplying the entire left lower lobe. Despite normal bronchial anatomy identified by CTA, the lobe received only systemic blood flow, effectively functioning as a physiologic pulmonary sequestration. After thorough conference discussion, the patient was scheduled for a cardiac catheterization and bronchogram to assess hemodynamics and bronchial anatomy. These results will inform future management. At his recent follow-up visits, weight gain continues to be an issue along with an ongoing respiratory illness.

Discussion:
This infant’s clinical course—limited to recurrent URIs and slow weight gain—contrasts with typical MAPCA presentation, associated with more severe risk factors, and is more so related to large shunt physiology. The MAPCAs role as the sole blood supply to the left lower lobe further amplifies the uniqueness of this presentation. The absence of CHD or pulmonary pathology makes the etiology of this MAPCA unclear. This report expands the clinical spectrum of MAPCA presentations and emphasizes the importance of early cardiac evaluation, even in low-risk infants with subtle symptoms.

Isolated Major Aortopulmonary Collateral Physiologically Mimicking Pulmonary Sequestration

Chylothorax, a rare complication of hepatic cirrhosis, is often under-recognized in the absence of ascites or other classical signs of portal hypertension. The diagnosis can be challenging due to its infrequent presentation, which highlights the clinical significance of this case. A 57-year-old male with a history of decompensated liver cirrhosis presented with progressive dyspnea. Imaging showed a right-sided pleural effusion. Pleural fluid analysis confirmed chylothorax, with elevated triglycerides and normal cholesterol levels. The patient underwent chest tube placement, which resulted in drainage of 2L of chylous fluid and marked symptomatic improvement. Further management included admission to the intensive care unit, initiation of total parenteral nutrition, and transition to a low-fat diet. The patient was transferred to an academic center as his clinical status failed to improve. This case portrays the diagnostic challenges of the etiology of chylothorax in patients with hepatic cirrhosis and emphasizes the role of portal hypertension in disrupting lymphatic drainage. Increased awareness of this rare complication is essential for timely recognition and appropriate management.

Leaky Lymphatics: Uncovering an Uncommon Complication of Hepatic Cirrhosis

Background
Behçet’s Disease (BD) is a multisystem vasculitis with variable manifestations, including gastrointestinal involvement in 10–15% of cases. Intestinal BD often mimics Crohn’s disease or ulcerative colitis, making diagnosis challenging due to overlapping endoscopic and histologic features. While ileocecal involvement is typical, atypical patterns can obscure recognition. This case highlights an unusual presentation of intestinal BD without ileocecal predominance, underscoring the need for clinical vigilance and systemic evaluation to differentiate it from primary IBD.
Case Presentation
We present a 40-year-old woman with a known 10-year history of BD, on colchicine and hydroxychloroquine, was admitted with hematochezia, recurrent vomiting, and severe anemia (Hb 5.1 g/dL). Clinical examination revealed oral aphthous ulcers, genital ulcers, and erythema nodosum. Colonoscopy showed skip lesions, mucosal erythema, and superficial ulcers throughout the colon, terminal ileum, and ileocecal valve. Biopsy revealed edematous lamina propria infiltrated by lymphocytes, neutrophils, and eosinophils without granulomas, transmural lymphoid aggregates and granulomatous lymphangitis consistent with intestinal BD. The diagnosis was confirmed using the International Criteria for Behçet’s Disease (ICBD score = 6). The patient responded well to colchicine, with resolution of GI symptoms within four weeks.
Discussion
This case illustrates an uncommon presentation of intestinal Behçet’s Disease with diffuse gastrointestinal involvement without the typical ileocecal predilection. The similarity in clinical presentation and colonoscopy findings to inflammatory bowel disease highlights the diagnostic challenge. In such circumstances, histopathological evaluation becomes crucial. In our patient, the diagnosis was guided by systemic features and confirmed with ICBD criteria and biopsy study. The novelty lies in the atypical distribution of lesions, reinforcing the need to consider intestinal BD in patients with unexplained GI bleeding and mucocutaneous symptoms. Early recognition and appropriate immunomodulatory therapy can prevent misdiagnosis, reduce morbidity, and avoid unnecessary surgical interventions.

Gastrointestinal Bleeding in Behçet’s Disease: A Dual Pathology or Mere IBD Mimicry?

Like the governmental control that led to the involuntary sterilization of Civil Rights Activist Fannie Lou Hamer and thousands of others, Project 2025, a political proposal written by the Heritage Foundation, plans to restrict the reproductive rights and bodily autonomy of women by eliminating abortion access. Individuals should have the right to choose how and when to reproduce without risking their health or feeling unprepared. 
As defined by Critical Race Theory, using colorblind perspectives when creating policies does not change the implicit biases of people or how social structures are maintained throughout history, and policies should be evaluated based on how they impact the most disadvantaged groups. Project 2025 aims to fully ban abortion to “heal the family crisis”, the idea that the lack of fathers and healthy families are what cause poverty, crime, etc. However, a complete abortion ban only furthers systemic racism and increases barriers to care for marginalized groups, a practice that has historically discriminated against women of color. In addition to harming citizens, the proposal for a nationwide abortion ban is in violation of international standards that the US has agreed to as a member of the United Nations.

Restriction of Reproductive Autonomy: From Eugenics to Abortion

Background 
Eating disorders (EDs) are complex psychiatric conditions with systemic implications, including a range of dermatologic manifestations. Cutaneous findings related to nutritional deficiencies and disordered behaviors may appear early in the disease course, sometimes preceding a formal diagnosis. Despite their diagnostic relevance, these manifestations are frequently overlooked in clinical practice. This review highlights the critical role of recognizing dermatologic signs in EDs to enable earlier detection, support comprehensive evaluation, and promote interdisciplinary management.

Methods
A systematic literature review and meta-analysis were conducted using PubMed and Google Scholar, encompassing studies published between 2020 and 2025. Nine peer-reviewed studies were selected based on their relevance and inclusion of data on the dermatologic manifestations of eating disorders, focusing on nutritional deficiencies, clinical presentation, and diagnostic value.

Results 
Xerosis was the most frequently reported cutaneous finding in both anorexia nervosa and bulimia nervosa, often accompanied by cheilitis, hypertrichosis, alopecia, acrocyanosis, periungual erythema, nail changes, and oral manifestations related to nutritional deficiencies and purging behaviors. Similar dermatologic patterns were noted in pediatric populations, with additional features such as lanugo and signs of self-injury. Several studies also reported a significant association between atopic dermatitis and eating disorders, potentially linked to negative body image and immune dysregulation.

Conclusion
Dermatologic manifestations of eating disorders are often overlooked, despite their potential to support earlier diagnosis and intervention. Greater clinical recognition of these signs can promote timely, multidisciplinary care and improve patient outcomes. Continued research is needed to clarify the underlying mechanisms and define the role of dermatologic findings in comprehensive eating disorder management.

Dermatologic Manifestations of Eating Disorders: An Underrecognized Diagnostic Intersection

Background

Ensuring alignment between lecture content and defined learning objectives is critical for LCME accreditation (Standards 6, 7, and 8) and improving student outcomes. Traditional curriculum mapping is time-intensive, manual, and variable. This project introduces a web-based tool that automates the analysis of medical lecture transcripts against defined course objectives. The tool enables medical school deans to rapidly perform gap analyses, provide faculty feedback, and improve outcomes. It integrates with Learning Management System (LMS) platforms to quantify objective alignment.

Methods

We developed a process using a Large Language Model (LLM) to parse pre-clinical lecture transcripts and compare them against predefined learning objectives. The project consists of three phases. In Phase 1, we developed a 100-point scoring system to quantify alignment. As a preliminary experiment, we analyzed eight publicly available medical school lectures and their corresponding objectives using ChatGPT’s o3 LLM model. We tested three unique prompt engineering workflows with objectives and transcripts as input. The outputs included alignment scores and narrative reports based on the Bloom Rating System for each objective then identifying opportunities for improvement. In Phase 2, we will refine the scoring system in collaboration with deans and faculty to ensure feedback is actionable. Phase 3 will incorporate this feedback and finalize the scoring process, along with building a simple web interface for non-technical users.

Results

After calculating alignment scores for each objective across all eight lectures, the scores were averaged to determine the overall alignment for each of the three distinct LLM workflows. The workflows produced average scores of 88.65, 84.6, and 65.89 across the lectures. Reports included specific feedback and timestamps highlighting improvement areas (e.g., topic depth, anecdotal stories, unaddressed objectives). Anticipated findings include average objective coverage per lecture, frequency of missed objectives, and early feedback on the tool’s utility.

Conclusion

This project offers a reproducible, scalable method to evaluate alignment between lecture content and curricular objectives in undergraduate medical education. By automating the review process, it supports data-driven faculty development and curriculum improvement while reducing administrative burden. Preliminary findings demonstrate that LLMs can quantify alignment using lecture transcripts. The project builds on institutional experience with AI-assisted curriculum mapping and targets broad use, especially in programs lacking curriculum analytics infrastructure. Next steps include integrating user feedback and piloting the tool with institutional content.

Automating Lecture-to-Objective Coverage:
A Tool for Curriculum Quality Improvement

Abstract Title: Single Authorship Trends in High-Impact Otolaryngology Journals: A Bibliometric Analysis
Educational Objectives: 
As the quality of evidence-based research continues to evolve, authorship trends would be expected to change in parallel. Single-authorship has never been used to characterize this phenomenon in academic otolaryngology.
Objectives:
To characterize trends in single-authorship in otolaryngology literature over the last three decades.
Study Design: Bibliometric Analysis
Methods:
The Web of Science was queried for studies published in first-quartile impact factor otolaryngology journals between 1994-2024. Single-author publications were identified via manual coding. The studies were analyzed by publication type, country of origin, open access status, and five-year total citation accrual. Results were compared between studies published in each decade, including 1994-2003 (D1), 2004-2013 (D2), and 2014-2023 (D3).
Results:
Out of 62,897 identified total publications in the study period, 4,322 (6.87%) were single-author studies. The rate of single authorship significantly decrease in each decade (D1: 12.5%, D2: 6.6%, D3: 4.7%, p < 0.00001). 
• In 1999, 8.03% of publications were single author
• In 2009, 6.4% of publications were single author.
• In 2019, 4.96% of publications were single author. 
• This matches the overall trend of the decades. 
The proportion of single author studies categorized as “articles” in the Web of Science also decreased from 1999 (3.7%) to 2009 (2.69%) and 2019 (1.1%, p < 0.00001), respectively. Five-year citation accrual of single-author articles increased throughout the study period (1999: 3.69 citations per article, 2009: 6.36 citations per article, 2019: 16.23 citations per article). For comparison, five-year citation accrual of multi-author articles is 7.01 citations per article for 1999, 9.89 citations per article for 2009, and 14.54 citations per article for 2019.
Open access distinction for single author articles increased over the study period (1999: 1/35, 2009: 6/41, 2019: 9/28)
The USA had a majority of single author articles in 1999 with 23 out of 35. The USA and Australia tied for most single author articles in 2009, each 7 out of 41. The USA had the most single author articles in 2019 with 10 out of 28.
Conclusion:
Single-author articles in high-impact otolaryngology journals steadily decreased over the last three decades. When looking at a representative year in each decade, citations per article increased across the study period even in proportion to the increase in multi author citations per article. These findings suggests the importance of single authorship in producing impactful papers in the field of otorhinolaryngology and raises concerns with shifting to multi author publications.

Single Authorship Trends in High-Impact Otolaryngology Journals: 
A Bibliometric Analysis

Background: African Americans (AA) with a history of psychosis and or schizophrenia are overrepresented in the prison population. This may be due to schizophrenia being more frequently diagnosed in racialized individuals, who also face higher incarceration rates. African Americans also under-report experience or history of mental illness during and after incarceration. They are also less likely than their white counterparts to seek mental healthcare upon release. Upon release, the shadows of incarceration in the form of barriers to re-entry contribute to the poor transition of mental healthcare and psychosis management amongst AAs. For AA males specifically, their multiple intersections of race, gender, and criminal record cause them to be viewed as even more socially unacceptable
Methods:This study examines continuity of care by analyzing treatment outcomes through antipsychotic prescriptions and other mental health service use among formerly incarcerated individuals on Medicaid or similar programs within 6–12 months post-release.
Results: Overall, connection with health services following release demonstrated better treatment continuity. States with policies on expedited referral or pre-release enrollment for Medicaid, also demonstrated greater use of mental health services within 6 to 12 months after release (Wennerstrom, Morissey). However, expedited Medicaid approval is more likely for whites than non-whites. Non-whites also had a higher likelihood of using community based mental health services (Gary, Hedden). 
Conclusion: Timely, appropriate mental healthcare for justice-involved individuals with schizophrenia reduces violent recidivism and government spending (Igoumenou, Lin), highlighting its role in crime reduction, rehabilitation, and societal reintegration. Expedited enrollment in Medicaid is an effective solution to bridge the gap in care. Ultimately, insight is lacking into the nuances of race as a factor impacting continuity of psychosis management, despite its prominence in the sphere of psychosis diagnoses and incarceration of African Americans
Keywords: Incarceration, Post-release Race, Psychosis, Schizophrenia, Mental Health, Anti-psychotics, Medicaid, African-American.


Racial Disparities in Post-Incarceration Psychosis Management

Background
Increased prevalence of chronic disease and the rising demand for healthcare services necessitates innovative approaches to address these challenges. Fresh and Savory Culinary and Lifestyle Medicine Program (FSCLMP) is a shared medical appointment (SMA) started in 2017 and transitioned to a virtual setting during the COVID-19 pandemic. SMAs, especially those centered on lifestyle medicine, have gained traction in recent years as an efficacious and cost effective therapeutic modality for treating chronic modifiable disease. This study sought to understand the efficacy of teaching kitchens through the virtual FSCLMP on self-reported lifestyle habits and confidence in maintaining lifestyle changes and patients’ biometric outcomes. 

Methods
Our study used pre and post intervention surveys to evaluate the impact of participation in FSCLMP on patient nutrition, biometrics, and overall confidence in maintaining lifestyle goals.. We further examined how these changes impacted patients’ biometric outcomes like blood pressure and BMI. This study was supported by our institution’s Institutional Review Board.

Results
There were 207 participants across seven cohorts of FSCLMP. Of these participants, 207 pre-surveys and 108 post-surveys were collected with a total of 81 matched pairs identified for evaluation. The average age of participants was 63.2 (SD = 9.23). Patient consumption of fast food, packaged foods, and sugary drinks significantly decreased (p = 0.0001) after participation in the program. Our analysis showed a significant decrease of participants’ BMI, from a mean BMI of 32.06 (SD = 6.79) to 31.17 (SD = 7.49) (p=0.02489). There was also significant improvement in self-perceived overall health (p=0.00002), with 92.6% of participants reporting a slight or significant improvement since graduating the program.


Conclusion
Our study found that participation in the virtual FSCLMP led to better eating habits and improved biometrics for patients. Participants had significant decreases in BMI and diastolic blood pressure, ate more meals made with fresh ingredients with decreased consumption of fast food and sugary drinks, and had increased self-efficacy when preparing plant-based meals. Overall, the virtual FSCLMP promoted key lifestyle changes, including consuming less processed products, increasing physical activity, and improving self-perceived health. These findings not only reflect the benefits of FSCLMP for participant health and wellness, but also suggest a crucial role for virtual teaching kitchens in helping patients with modifiable chronic diseases maintain nutrition and lifestyle goals.
