Background: Previous studies have demonstrated an association between Black race and poorer overall survival for patients with mycosis fungoides (MF). As for Hispanic patients (HPs) with MF, little is known within the literature.1–4 Due to the impact treatment may have on overall survival, we identified racial and ethnic factors associated with the receipt of treatment for MF.

Methods: A retrospective analysis of 8257 eligible patients diagnosed with MF between 2004 – 2017 within the National Cancer Database (NCDB) was performed. Multivariate logistic regression was used to identify sociodemographic factors, clinical factors, and the receipt of treatment (immunotherapy, chemotherapy, radiation, or other treatments) associated with non-Hispanic Black patients (NHBPs) and Hispanic patients (HPs), compared to non-Hispanic White patients (NHWPs). Covariates included age, sex, stage, median household income, facility type, insurance status, metro/non-metro, and Charlson-Deyo score.

Results: NHBPs and HPs consisted of 20.2% and 6.4% of patients within the study, respectively. NHBPs were less likely to receive radiation compared to NHWPs, adjusting for sociodemographic and clinical factors (aOR 0.71; 95% CI: 0.58 – 0.86; P= &lt;.001). NHBPs were more likely to receive other treatments such as psoralen and long-wave ultraviolet radiation (PUVA) (aOR 1.39, 95% CI: 1.22 – 1.60, P = &lt;.001). HPs were more likely to be diagnosed with Stage 4 disease (aOR 2.67; 95% CI: 1.73 – 4.03; P= &lt;.001). No differences were noted in the receipt of treatment due to Hispanic ethnicity. 

Conclusions: NHBPs with MF were 29% less likely to receive radiation compared to NHWPs. NHBPs were 39% more likely to receive other treatments like PUVA, after adjusting for sociodemographic and clinical factors. HPs were nearly 3 times more likely to be diagnosed with Stage 4 disease compared to NHWPs, after adjusting for sociodemographic characteristics and stage. These results underline possible difficulties in accessing equitable therapies for NHBPs with MF.

Welcome to the largest national, multi-specialty research event featuring research from 750 medical students, residents and fellows, and international medical graduates.


Background: 
Although white patients have higher incidence of melanoma, clinical outcomes are worse among patients with skin of color. This disparity arises from delayed diagnoses and treatment that are largely due to clinical and sociodemographic factors. These include: atypical presentation, decreased skin health literacy, stereotype threat, limited access to dermatologists, and poverty rates. Investigating these disparities is crucial to decrease the disparity in melanoma-related mortality rates in minority communities.

Methods: An extensive search of current literature was conducted using PubMed Database. Articles focusing on melanoma diagnoses, treatment, and race were reviewed to determine the current state of literature on melanoma, racial disparities, and health literacy. A 16 question survey was designed and deployed via Qualtrics to measure whether the presence of racial disparities in dermatologic awareness exists and if they may be due to social and economic factors. The survey was distributed on various social media platforms, and sites related to skin cancer or melanoma. Over 300 results were recorded and the extracted data was analyzed using SPSS software.

Results: 
Of the 308 respondents, white patients were significantly more likely to have higher perceived risk of developing skin cancer, highest self reported understanding of UV scale, highest levels of sunscreen usage, and higher reported frequency of skin checks performed by primary care providers (PCPs). There was no difference in levels of melanoma education provided by PCPs among different racial groups, and no significance identified in the highest level of patient education perceived melanoma risk. 

Conclusion:
Initial literature analysis suggests attribution of racial disparities in skin cancer to inequity in primary care settings. As a result of differential presentation and lack of dermatologic access both geographically and financially, there is delayed diagnosis and treatment time. The survey findings above do not suggest inadequate dermatologic literacy as provided in healthcare settings, but rather inadequate dermatologic health literacy as a result of other outlets such as public health and skin product marketing. Outlets such as racial stereotypes in communities, implicit biases in marketing companies, and public health campaigns should be considered. Further studies should be conducted to determine these biases and improve education in communities of color. 



Racial Disparities in Melanoma: Barriers to Diagnosis, Treatment and Health Literacy

Background
Patients experiencing homelessness (PEH) are at high risk of skin cancers due to the amount of sun exposure they receive on a daily basis. Skin disease can be overlooked and underdiagnosed in PEH due to their lack of access to healthcare, and connecting patients to appropriate specialists is a major hurdle in bridging their health disparities. Miami Street Medicine (MSM) is an organization that connects PEH in the Miami Medical District with longitudinal care. This project aims to raise awareness about the risk of skin cancers in PEH and describe a way MSM was able to bridge care for an unhoused patient with melanoma.
Methods
PEH encountered during weekly mobile clinics from January - May 2022 were provided basic medical care (vitals, wound care, medications) followed by a skin survey. A board-certified dermatologist was consulted for conditions with low diagnostic certainty. Further, patients were provided with guided treatments for their condition. Patients with high-risk lesions were connected to low-income clinical resources for further management and were concurrently followed by Street Medicine teams to improve treatment access and adherence.
Results
Among 106 patients interviewed, 102 skin conditions were diagnosed. A total of 8 lesions (7.8%) found were suspicious for cancer or pre-cancer, with 1 pathology-confirmed melanoma. Numerous barriers to care were encountered such as insurance limitations, lack of health literacy, transport issues, and lack of social support which made appointment adherence challenging. The patient with a lesion suspicious for melanoma was followed closely and scheduled for further evaluation, with eventual pathology confirmation of melanoma-in-situ. He is currently being followed by a multidisciplinary team including mental health professionals, and surgically evaluated for excision and reconstruction.
Conclusion
Skin cancer is an area of concern for PEH because of their extensive sun exposure. For many PEH, inpatient hospitalization is often the only way to access specialty care. This means that a multifaceted approach is required to improve treatment adherence, which can also include point-of-care testing or telemedicine specialist consultations. Street medicine can be a valuable adjunct to improving longitudinal care among PEH by bridging the gaps that prevent follow-up in the current healthcare delivery model.

Skin cancers among the unsheltered: a Street Medicine perspective

Background: Wildfires are a worsening public health crisis, threatening human health and healthcare infrastructure. Of the largest wildfires in California since 1878, four occurred in 2021 and five in 2020. Despite the increasing frequency of healthcare facility and community evacuations due to wildfires, little is known regarding the extent of wildfire threat to healthcare access in California. We examine where inpatient healthcare facilities are at the greatest risk of potential structural damage or facility evacuation based on fire threat data.

Methods: Inpatient facility locations including i) general and acute care hospitals, ii) behavioral health facilities, and iii) long term care facilities were mapped in relation to CAL-FIRE Fire Threat Zones (FTZs), which combine expected fire frequency with potential fire behavior. The threat zones within a half-mile and one-mile radius of each facility were computed and recorded as a metric of potential threat to the physical structure, operation, or accessibility of the facility. Regional risk profiles to facilities and facility capacity were calculated.

Results: Of 3,096 inpatient healthcare facilities, 908 (29%) are within 0.5-miles of a “high”, “very high,” or “extreme” FTZ (‘higher’ FTZ), and 1,514 (49%) within one mile. In 18 counties, 100% of inpatient healthcare facilities are within 0.5 miles of higher FTZ; in 25 counties (population 2.6 million), 100% of inpatient healthcare facilities are within one mile of higher FTZs. 67% of the inpatient healthcare facility capacity in California is within one mile of a higher FTZ. 

Conclusion: A substantial proportion of California’s inpatient healthcare infrastructure is threatened by wildfire, and this risk is unevenly distributed. In northern counties – where two of California’s largest fires burned more than one million acres in the last two years – healthcare accessibility is a significant concern because of high levels of hazard exposure and limited total number of facilities, meaning loss of a single facility can substantially affect healthcare access. As climate change and other factors raise wildfire risk, it will be important to invest in measures to protect inpatient healthcare facilities and ensure that these facilities continue to meet the healthcare needs of their communities.


An Analysis of Wildfire Threat to Inpatient Healthcare Facilities in California

Background
Depression is a common mental disorder among the geriatric population that reduces the quality of life and increases morbidity and mortality. Vitamin D is a neurosteroid hormone involved in various brain functions. Vitamin D receptors (VDR) are expressed in many brain regions, such as the hippocampus, hypothalamus, and cerebellum. It regulates the gene expression of various neurotransmitters. Furthermore, Vit D enhances the production of serotonin which suppresses depressive symptoms. Vit D deficiency is relevant in older persons and associated with an 8-14% increase in the risk of depression, particularly in subjects with low serum 25-hydroxy-vitamin D (25OHD) levels. The objective of this study is to examine the effect of Vitamin D supplements in the management of depressive symptoms in the elderly.
Methods
We searched PubMed, Google Scholar, and Clinicaltrials.gov to collect the relevant studies that examined the effects of vitamin D supplementation on depression. We used a combination of the keywords; Depression, Vitamin D, Vitamin D supplements, and Elderly to search databases. The studies collected were randomized controlled trials (RCT) in the elderly population, published within the last decade. We excluded non-English articles, observational studies, and animal studies.
Results
We reviewed eight RCTs that matched our predetermined eligibility criteria. The studies included 55,451 male and female participants. The risk and clinical symptoms of depression were assessed between the Vitamin D3 supplement groups and the control groups. Six studies showed no significant reduction in depression symptoms after Vitamin D3 supplementation. The other two studies reported improvement in depressive symptoms and a significant decline in depression scores.
Conclusion
We found a clear association between low levels of 25-hydroxyvitamin D and increased risk of depression in elder persons. However, included clinical trials, except for two studies, did not show a significant correlation between vitamin D3 supplementation and amelioration of depression symptoms in the elderly. Few studies have a small sample size which might be a limitation of this review. Future clinical trials on larger populations and longer duration are needed to investigate the causal relationship and treatment recommendations.




The Effect of Vitamin D Supplements in the Treatment of Depression in the Elderly: Literature Review

Background:
Helicobacter pylori (H. pylori) bacteria has long been scrutinized as one of the potential risk factors for developing pancreatic cancer with inconsistent and unequivocal data. Globally, there is an increasing trend in pancreatic cancer incidence and mortality rates. Little is known about the risk factors involved with this malignancy. In this systematic review, we aimed to examine the relationship between H. pylori infection and pancreatic cancer based on the evidence from the existing observational studies worldwide.

Methods:
We searched major electronic databases such as PubMed, MEDLINE, Science Direct, and Cochrane library using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 guidelines. After a careful and thorough screening process, we selected 15 observation studies for this systematic review.

Results:
Six of 15 studies found a significant association between H. pylori infection and pancreatic cancer. Additionally, four of these studies found a significant relationship between the Cytotoxin-associated gene-A (CagA) strain of H. pylori and pancreatic cancer.

Conclusion:
Based on the evidence from the selected studies, a weak association was observed between H. pylori infection and cancer of the pancreas, especially in European and Asian populations compared to the North American population. The cross-sectional evidence from the case-control studies only suggests the existence of association but does not provide substantial evidence of the causative relationship. Further, large-scale prospective cohort studies are warranted in the future to understand this contradictory relationship better.

Association between the Helicobacter pylori Infection and the Risk of Pancreatic Cancer

Abstract Title: Cultural adaptation of Web-based Dietary Intervention Platform ALIVE – to improve the dietary inflammatory scores among the African American People in the CHURCH trial.
Soujanya Jammalamadaka, under the guidance of Dr. Lisa Matthews, and Principal Investigator Dr. Olajide A. Williams, Columbia University Irving Medical center.
Background:Structural inequities contribute to the high rates of colorectal cancer(CRC) incidence(49.1%) and mortality rates(23%) among African Americans(AA) compared to other races in the USA. Screening and dietary/lifestyle modification are effective ways of preventing or reducing the risk of CRC. Research suggests that culturally tailored interventions could improve patient health outcomes and highlight the lack of scientific rigor in cultural adaptation. The CHURCH trial is a cluster RCT aimed at preventing CRC in the AA population via screening and dietary/lifestyle modification. The trial employed the Ecological Validity Model(EVM)9 for cultural adaptation of the dietary intervention designed to reduce the consumption of a pro- inflammatory diet known to increase CRC risk.

Methods: The ALIVE platform is an NCI EBCCP-indexed cost-effective lifestyle coaching program with high RE-AIM scores and framework scores for real-world translation. Using the eight targeted EVM dimensions and an antiracism lens guided by Public Health Critical Race Praxis, we adapted the ALIVE platform to be sociocultural, linguistically, and economically appropriate for AA churchgoers. Specific components of the ALIVE platform included small-step goals, motivational messaging, infographics, media components, and health notes. Before applying the EVM, we employed the community-based participatory research(CBPR) approach to identify the barriers and facilitators to participation and specific EVM dimensions for adaptation within ALIVE! A Community Health Worker(CHW) leader incorporated into our committee assembled a small team of CHW leaders(n = 6) to support community decision-making. In partnership with these leaders, we conducted focus groups with 24 AA church members. We administered a semi-structured survey to 34 CHWs to help inform the design and dietary content and identify problematic EMV-related dimensions.
Results: We successfully identified specific EVM dimensions for adaptation within ALIVE! Focus group findings revealed contextualized health issues in a broader social context, such as structural racism and discrimination. Our survey findings guided the content of the ALIVE platform.
Conclusion: Cultural adaptation of a web-based dietary intervention can be conducted using a CBPR framework, which can aid in identifying EVM dimensions of a web-based nutritional intervention targeting CRC. The next phase of our cultural adaptation process will involve micro- adaptation activities involving eight EVM dimensions.

Cultural adaptation of dietary intervention platform - ALIVE! for colorectal carcinoma prevention.

Background:

The United States Preventive Services Task Force recommends colorectal cancer (CRC) screening for all average-risk adults aged 45 years and up1. Fecal Immunochemical Tests (FIT) and FIT/DNA (Cologuard) test are the two most widely used non-invasive tests used for this screening. In the event of a positive test, a diagnostic colonoscopy is recommended within three months of the positive result. As the Covid-19 pandemic continues, hospitals have implemented policies that include strict screening guidelines before procedures such as colonoscopies. The effect of these guidelines and restrictions on elective procedures such as colonoscopy on the interval between a positive non-invasive screening test (NIST) and diagnostic colonoscopy (DC) is not clear.
Study aim: to quantify the interval between a positive NIST (FIT, FIT/DNA) and DC, and to compare these findings to non-pandemic findings from the previous year. 


Methods:
In this retrospective, time-trend analysis, we identified patients within a major hospital system in Indiana who had a positive NIST between January 1, 2019 and June 30. After our original query, we noticed FIT/DNA tests were not coded into the EMR before June 10, 2020, and had to use data from campus-based public and private hospitals to supplement for this time period. Once identified, chart review was performed to determine if/when a patient underwent DC . If a patient’s chart did not show evidence of a DC, we examined the EMR notes to discern whether, when, or why colonoscopy was / was not completed. We measured the interval between NIST result and DC by quarter, comparing results between corresponding times during 2019 and 2020 as well as the first two quarters of 2021. We also measured and compared the proportion of patients with a positive non-invasive test who had not had colonoscopy by 60, 90, and 180 days. 


Results:
Of the 1,379 patients reviewed, 930 (68%) underwent subsequent colonoscopy in the 30-month study timeframe. Colonoscopy completion rates were 72% for the FIT/DNA group, and 47% for the FIT group over the 30-month timeframe. Of the 293 persons who did not elect to have a subsequent colonoscopy, 21 (7.2%) reported that the pandemic kept them from undergoing the procedure. Concern for acquiring COVID-19 from the colonoscopy site was the most common reason for declining colonoscopy in this group, having been mentioned by 8 of the 21 individuals. Other reasons included waiting to get a COVID vaccine before undergoing a procedure or issues with completing required COVID screening before the procedure. Only two individuals (0.7%) were found to have delayed colonoscopy due to a recent COVID infection. The proportion of patients completing a colonoscopy within 90 days of a positive NIST were 83%, 79%, and 83% for 2019, 2020, and 2021, respectively.


Conclusion/Impact:

Overall, the rate of DCs following a positive NIST test did not appear to be significantly affected by the COVID-19 pandemic. Concern of contracting COVID-19 was a more common reason for delay when compared to actual COVID infection. A study evaluating the rate of COVID infection following a colonoscopy procedure may be useful to address the validity of these concerns, the results of which could alleviate (or exacerbate) this issue in the setting of future outbreaks. When compared to Cologuard, patients who had a positive FIT test were more likely to wait longer for a DC. This discrepancy suggests the relationship between providers and their use of FIT vs. Cologuard should be further probed. In addition, studying patient perceptions of both screening procedures may identity reasons for delay.

Interval Between A Positive Non-invasive Colorectal Cancer Screening Test and Colonoscopy: A Time-trend Analysis During the SARS-CoV2 Pandemic

Background
This study sought to describe the levels of depression and anxiety experienced by English and Spanish-speaking patients undergoing radiation therapy for breast cancer. We aimed to describe the impact of different variables to better understand and quantify potential gaps.

Methods
Eligibility criteria included English and Spanish-speaking females, ages 18 or older, undergoing radiation therapy treatment for a breast cancer at Boston Medical Center. Surveys were completed before delivery of radiation therapy. Survey included sociodemographic questions along with the standardized PHQ-4 questionnaire, which uses a maximum total score of 12, to assess anxiety and depression. Results were analyzed using a least means square procedure.

Results
60 participants completed surveys, with a total distress mean (DM) of 3.32 (SD= 3.55). English-speaking patients comprised 70% (n=42) of the sample and had a DM of 3.40. Spanish-speaking patients comprised 30% (n=18) with a DM of 3.11. Sociodemographic characteristics included: race -- 27% White (n=16), 46% Black (n=28), 27% other (n=16); ethnicity -- 67% non-Hispanic (n=40), 33% Hispanic (n=20); marital status -- 37% never married (n=22), 33% married (n=20), 30% divorced/ separated/widowed (n=18); education level -- 20% < High school (n=12), 60% high school/associate’s (n=36), 20% bachelor’s/master’s/doctorate (n=12); and longest residence -- 60% US (n=36), 40% foreign country (n=24). Additional variables surrounding social determinants of health included housing and food insecurity. 

Conclusion
Our study showed a higher baseline DM among English-speaking patients in comparison to Spanish-speaking patients. Most of our patient population was English-speaking, though approximately one third Spanish-speaking. Participants were also primarily Black, non-Hispanic, never married, had a high school or associate level education, and had their longest residence in the US. Although the majority did not report housing or food insecurity, both had increasing DM with increased insecurity, with statistically significant results. This study provides insight into a patient population that has historically been understudied, particularly Black and Hispanic patients, that comprise ~29% of the US population, but make up less than 10% of participants in cancer clinical trials. In addition, as the number of Spanish-speakers in the US continues to increase, it will be important to understand and address potential differences in cancer care.

A Comparative Assessment of Depression and Anxiety in English-Speaking and Spanish-Speaking Breast Cancer Patients Undergoing Radiation Therapy

Background: Black mothers have worse birth outcomes than White mothers. Historic medical abuses and systemic racism render a sense of mistrust between Black birthing individuals towards their obstetric healthcare providers and may result in Black birthing people seeking medical advice from doulas outside their traditional practice scope. Objective: The objective of this study was to create a structured collaborative curriculum between community doulas and academic obstetric providers to address common prenatal and postpartum pregnancy complications that disproportionately affect Black birthing people. 
Study Design: The collaborative training session was a two-hour session jointly developed by the founding director of Homeland Heart Nashville Birth and Wellness Collective, a Vanderbilt Maternal-Fetal Medicine Specialist, and a Vanderbilt Certified Nurse midwife. On the day of the collaborative training, the doulas (n=12) took a pretest to assess their knowledge of postpartum warning signs, preeclampsia, breastfeeding, and GDM. After the didactic session, the doulas were given a post-test. The scores were averaged across the four pre and post-assessment topics. We calculated students' t-tests between the pre-and post-assessment. A p-value of < 0 .05 was considered significant. 
Results: All twelve participants identified as Black female birth workers. The mean score correct of the pretest results was 55.25±13.36%. The initial percent correct for post-birth warning signs, hypertension in pregnancy, and gestational diabetes mellitus/ breastfeeding sections were 37.5±19.55 %, 72.9±16.72 %, and 75±18.46%, respectively. The post-test mean score of correct answers rose to 91.92 ± 4.66% (p< 0.01). The percent correct per section increased to 92.7±9.91 %, 81.3±11.31 %, and 100±0 %, respectively. The student T-test calculated P-value from the pre-and post-test mean was < 0.01.
Conclusion: An educational framework that leverages community and academic partnerships between doulas and obstetric providers can bridge the gap to improve doulas’ knowledge and holds promise to improve Black birthing outcomes.

Collaborative Education as a Conduit to Build Trust and Skills in Black Birth Workers

Background
Covid-19 infection poses higher risks if contracted during pregnancy. Yet, COVID-19 vaccination rates in those who desire future fertility are low. Misinformation about COVID-19 vaccination leading to to female infertility has been common on social media. The objective of this study was to characterize the prevalence and content of misinformation about infertility and the COVID-19 vaccine on Twitter. 

Methods
Tweets were obtained from the COVID-19-TweetIDs dataset at two key points in the COVID-19 vaccine discourse (July 2021 and December 2021). All relevant tweets contained at least one word related to COVID19 vaccination and one word related to fertility and were analyzed for factuality. Descriptive statistics on followers, verification status, engagement, and common words and hashtags were obtained. ANOVA or Chi-square tests were utilized to examine differences between the factual and misinformation groups. A p value of <0.05 was considered statistically significant. Sentiment analysis was conducted to categorize tweets as positive, neutral, or negative.

Results
Overall, 11,436 tweets from Timeframe 1, and 5,982 tweets from Timeframe 2 were reviewed (n = 17,418). Misinformation tweets were 29.9% in July 2021 to 45.1% in December 2021. Accounts sharing factual information were more frequently verified users (p<0.001) and had increased follower counts (p<0.001). Engagement was similar in both factual and misinformation groups. Sentiment analysis revealed that factual tweets were more likely positive and misinformation tweets more often negative (p<0.001). 

Conclusion
Misinformation about the COVID-19 vaccine and fertility a serious problem on social media, and may limit vaccine uptake in people desiring future pregnancy. To combat misinformation, it is imperative to identify and denounce the misinformed content. Physicians must be aware of online misinformation to adequately address vaccine hesitancy in patients who are pregnant or trying to conceive. Twitter accounts sharing factual information were more likely to be verified, highlighting the need for more physicians’ accounts to be verified. Physicians can play an important role in fighting misinformation both in the office and online.
