Background:
Mixed aortic valve disease (MAVD) is defined as aortic stenosis (AS) occurring simultaneously with aortic regurgitation (AR), and is the most frequent concomitant valvular disease worldwide. Transcatheter aortic valve replacement (TAVR) is indicated based on guidelines for the primary lesion while considering the concomitant disease. TAVR seems to be associated with similar mortality rates in patients with MAVD compared to AS, while complications have conflicting data in literature. The aim of this study is to systematically synthesize the latest evidence to compare clinical outcomes of TAVR in MAVD compared to AS.

Methods:
Systematic literature review was conducted on PubMed and Embase for studies on outcomes of TAVR in MAVD from inception until April 2024. Data extracted from the articles included baseline characteristics and several outcomes. Primary outcomes were short- (&lt;30 days) and long-term (&gt;30 days) mortality. Secondary outcomes were complications in accordance with the Valve Academic Research Consortium-2 (VARC-2) consensus, including paravalvular regurgitation, vascular and bleeding complications, pacemaker implantation, and cerebrovascular events. A random-effects model was used to pool risk ratios (RR) and 95% confidence intervals (CI) for clinical endpoints, and was conducted using RStudio.

Results:
11 observational studies including 133,558 patients were included in the analysis. There were no significant differences in primary endpoints (p&gt;0.05). MAVD was associated with lower risk of cerebrovascular complications (RR: 0.65, 95% CI: 0.53-0.97) and higher risk of paravalvular regurgitation (RR: 1.29, 95% CI: 1.07-1.55). No significant differences were noted in other secondary outcomes (p&gt;0.05).

Conclusions:
The similar mortality risk of TAVR in MAVD compared to AS as well as higher risk of paravalvular regurgitation in MAVD is in accordance with most recent studies. However, this meta-analysis is the first to show a significantly lower risk of cerebrovascular events in MAVD patients. This study highlights the importance of future research to further delineate differences in procedural outcomes in this population.

Background: 
Psoriasis is a chronic, relapsing inflammatory condition that mostly affects the skin and joints. Recent data indicate that psoriasis is an independent risk factor for myocardial infarction (MI) and contributes to several cardiovascular (CV) risk factors, including metabolic syndrome, smoking, obesity, hypertension, insulin resistance, and dyslipidemia. Our study quantifies cardiovascular-related deaths among psoriasis patients, examines trends over time, and highlights demographic and geographic disparities to better understand the impact of these coexisting conditions. 

Methods: Data from the CDC WONDER database was analyzed to identify cardiovascular- related deaths among adults aged 25 and older with psoriasis in the United States from 1999 to 2020. Age-adjusted mortality rates (AAMRs) per 100,000 persons and annual percent change (APC) were calculated and stratified by year, sex, and age group. 

Results: Between 1999 and 2020, cardiovascular-related deaths in individuals with psoriasis accounted for 2,353 deaths among adults aged 25 and older in the US. The overall AAMR for cardiovascular-related deaths in psoriasis decreased from 0.87 in 1999 to 0.7 in 2020, with an Average Annual Percent Change (AAPC) of -0.9324 (95% CI: -1.5179 to -0.3276, p < 0.05). A significant decline occurred from 1999 to 2011 (APC: -5.0752; 95% CI: -6.6070 to -3.8388), followed by a notable increase from 2011 to 2020 (APC: 4.8738; 95% CI: 2.9977 to 7.5961). Men exhibited higher AAMRs compared to women. The AAMR for both men and women decreased, with a steeper decline for women from 1999 to 2011 (APC: -5.05) compared to men in the same period (APC: -4.97). Individuals aged 65 and older demonstrated a decline in AAMR from 1999 to 2011 (APC: -5.66), followed by an increase from 2011 to 2020 (APC: 4.69). Individuals aged 35 to 64 did not demonstrate a similar trend, with an APC of 0.48 from 1999 to 2020. 

Conclusion: This analysis reveals significant differences in cardiovascular-related mortality rates among individuals with psoriasis. Men had higher mortality rates than women, with a notable decline from 1999 to 2011 followed by an increase from 2011 to 2020. People aged 65 and older showed a similar pattern, while those aged 35 to 64 exhibited stable rates. These findings emphasize the need for targeted interventions to address the increasing mortality rates, particularly in older adults and men, to improve health outcomes for patients with psoriasis.

Trends and Disparities in Cardiovascular-Related Mortality Among 
Individuals with Psoriasis in the United States (1999-2020)

Background:
Heart failure and Diabetes are interrelated conditions, whereby the presence of one condition heightens the likelihood of developing the other. Given the poor prognosis of heart failure in diabetic patients, this study aims to quantify mortality rates among heart failure patients with and without diabetes. It examines trends over time and highlights demographic and geographic disparities to better understand the impact of these coexisting conditions.

Methods: Data from the CDC WONDER database was analyzed to identify heart failure- related deaths with and without diabetes mellitus among all age groups in the United States from 1999 to 2020. Age-adjusted mortality rates (AAMR) per 100,000 persons and annual percent change (APC) were calculated and stratified by year, sex, race/ethnicity, region, and urbanization.

Results: Between 1999 and 2020, heart failure-related deaths with diabetes mellitus accounted for 1,028,703 deaths, while heart failure-related deaths without diabetes accounted for 3,912,345 deaths. The overall AAMR for heart failure-related deaths with diabetes increased from 22 in 1999 to 27.3 in 2020, with an Average Annual Percent Change (AAPC) of 0.4646 (95% CI: 0.0134 to 0.8398, p = 0.0455). A significant decline occurred from 1999 to 2016 (APC: -1.2046; 95% CI: -1.8079 to -0.7404), followed by a notable increase from 2016 to 2020 (APC: 7.8768; 95% CI: 4.3018 to 16.9504). Men exhibited a higher AAMR than women (25.9 vs. 18.5). The American Indian or Alaska Native group had the highest AAMR, followed by Black or African American, with comparable levels for Hispanics or Latinos and Whites. Asian or Pacific Islanders had the lowest AAMR. Geographically, the Midwest, West, and South showed comparable mortality rates, while the Northeast had the lowest AAMR. Non-metropolitan areas had higher AAMRs than metropolitan areas (28.5 vs. 20.1), with a significant decrease in non-metropolitan areas (AAPC: 0.9306, p = 0.0016) and a non-significant decrease in metropolitan areas (AAPC: 0.4025, p = 0.0571).

Conclusion: This analysis reveals significant differences in mortality rates between heart failure with and without diabetes mellitus, based on demographic and geographic factors. While heart failure-related mortality rates initially declined from 1999 to 2016, a recent rise has been observed from 2016 to 2020. Men, American Indian or Alaska Natives, and those in non-metropolitan areas exhibited the highest mortality rates. These findings signify the need for targeted public health interventions to address these disparities and improve health outcomes for high-risk groups.

Trends and Disparities in Heart Failure Mortality With and Without Diabetes Mellitus in the US

Background 

The Arc of Riolan (AoR) is known to provide collateral vascularization between the Superior Mesenteric Artery (SMA) and the Inferior Mesenteric Artery (IMA), yet inconsistent definitions regarding the artery’s course exist. The AoR is a highly contested and confusing collateral artery among existing gastrointestinal arteries. The identification and preservation of the AoR is crucial to reducing the risk of acute colonic ischemia following splenic procedures. However, more details about the AoR 
prevalence and pattern are needed to corroborate the likelihood of finding this collateral artery in a patient. This study aimed to explore the prevalence and pattern of the AoR as defined by a connectionbetween the Middle Colic Artery (MCA) and Ascending Left Colic Artery (ALCA). 

Methods 
A total of fifty-two cadaveric colons were dissected at Tilman J. Fertitta Family College of Medicine and Baylor College of Medicine. Specific dissection techniques were employed to expose the ascending, transverse, and descending colon, and associated vasculature. AoR patterns were observed and photographed in all the donors. Photographic analysis followed dissection to determine whether a connection between the MCA and ALCA was present. 

Results 
The AoR was identified in six bodies (11.5%) as a smaller artery forming collateral circulation between the Ascending Left Colic Artery off the IMA and the Middle Colic Artery off the SMA. The AoR was thin in nature when compared with SMA and IMA arterial branches. The authors of this study hypothesize that corroborating previous Arc studies with additional prevalence data regarding the AoR connection will encourage and assist with the identification and preservation of the Arc during colonic procedures. 

Conclusion 
The AoR was identified in 11.5% of the colons examined and the artery’s course was noted. The frequency of the connection identified in this study matches existing AoR prevalence studies. Additional samples will be collected to determine the statistical significance of this pilot study. Vasculature and anastomotic connections among the transverse and descending colon are highly variable from patient to patient; however, surgeons must be aware of a collateral artery that connects the MCA with the ALCA, given that its frequency is about 11% among patients. Proper identification and preservation of the AoR could prevent post-operative ischemia following bowel resection. 



Exploring the Prevalence of the Arc of Riolan Artery in the Large Intestine - A Cadaveric Pilot Study

Background: The risk of developing cutaneous T-cell lymphoma (CTCL) in patients with psoriatic disease using tumor necrosis factor inhibitors (TNFi) has not been well characterized. This study aims to review the incidence of CTCL in clinical trials of TNFi and TNF inhibitor biosimilars used to treat patients
with psoriasis and other psoriatic diseases.
Methods: The US National Library of Medicine clinical trials database (clinicaltrials.gov) was queried to identify all phase 3 and 4 clinical trials of the 5 FDA-approved TNFi and TNFi biosimilar biologic therapies. The search was limited to clinical trials involving psoriatic diseases treated with TNFi and biosimilars. Trials involving the following psoriatic diseases were identified and included: psoriasis, psoriatic arthritis, generalized pustular psoriasis, and palmoplantar pustulosis. The incidence of CTCL in these trials was examined and summarized. Fisher’s exact test was performed to determine differences in the rate of CTCL between patients who received biologic therapy and those who received placebo treatments. A p-value less than 0.05 was considered statistically significant.
Results: Data from 98 phase 3 and 4 trials of TNFi and TNFi biosimilars were analyzed. No cases of CTCL were reported in 17,906 patients with psoriatic diseases who received TNFi in phase 3 trials. No cases of CTCL were reported in 4,066 patients with psoriatic diseases who received TNFi in phase 4 trials. No cases of CTCL were reported in 1,621 patients with psoriatic diseases who received TNFi biosimilar in phase 3 trials. There were no TNFi biosimilar phase 4 trials. Of the 3,283 patients who received placebo in phase 3 trials and 248 patients who received placebo in phase 4 trials, no cases of CTCL were reported. No difference was found between the incidence of CTCL in patients treated with TNFi and those treated with placebo in both phase 3 and 4 trials using the Fisher’s exact test (p > 0.05).
Lastly, no difference was found between the incidence of CTCL in patients treated with TNFi biosimilars and those treated with placebo using the Fisher’s exact test (p > 0.05).
Conclusion: Our findings indicate that the use of TNFi and TNFi biosimilars in the treatment of psoriatic diseases is rarely associated with the development of CTCL.

Assessing the Risk of Cutaneous T-Cell Lymphoma Associated with Tumor Necrosis
Factor Inhibitors and Biosimilars

Objective/Background 
Livedoid vasculopathy (LV) is a rare vasculopathy that affects the lower extremities, causing painful recurrent ulcerations, livedo reticularis and atrophie blanche.1 It might be idiopathic or present in association with hypercoagulable states or vascular disorders in 50-70%.2 Despite increased treatment options, patients often face suboptimal treatment outcomes.3 Data based on systematic review for treatment outcomes of LV are initially needed to identify gaps of knowledge and inform next steps in clinical trial design. 

Methods 
We searched major databases from January 2017 to October 2023 using key terms related to Livedoid Vasculopathy and its treatment outcomes. We included case reports, series, cross-sectional and retrospective studies (excluding reviews and articles without defined treatment outcomes). Analysis followed PRISMA guidelines with two reviewers independently assessing studies. Conflicts were resolved by a third party. 

Results 
Out of 614 articles identified, 44 were included in the final review, most of which were case reports or series. In total, there were 216 participants (155 female, 61 male) with median age 44 years (14-73). 

Rivaroxaban was the most reported treatment (n=58), showing complete (n=18, 31%) or partial (n=40, 68%) ulcer healing and complete pain resolution in the 19% reported. Other factor Xa inhibitors (n=4) led to complete wound healing and pain relief in our review. IVIG (n=36) showed promising results in wound and pain resolution, though some patients did not achieve adequate healing (n=4, 11%). Less common treatments like hyperbaric oxygen therapy (n=3), anti-TNF (n=1), and others also achieved complete healing and pain improvement. 

Conclusion 
A variety of therapeutic strategies for LV have shown promise, but data to support any specific regimen remains lacking. In recent literature, Rivaroxaban was the most used therapy with 82.2% (60/73) of patients achieving rapid healing and pain relief.4 IVIG disrupts inflammatory cytokines, modulates lymphocytes, and neutralizes autoantibodies, making it a potential treatment for LV due to the presence of these markers in LV patients.5 Future directions consist of determining which patients (with primary or secondary LV) might benefit from single or combined therapies and establishing standard of care for this condition that can also be used as a comparator arm in clinical trials.

Introduction
Nevus of Ota presents as unilateral benign melanosis in the distribution of the trigeminal nerve, with increased risk of uveal melanoma and glaucoma¹.
Since the advent of selective photothermolysis, Q-switched nanosecond lasers have been reported for treatment of dermal pigmented lesions⁷. Two prospective, randomized, split-lesion, controlled studies have concluded that picosecond lasers were more effective³. In these cases, treatment until clinical clearance was performed. We would like to report a case of nevus of Ota that was treated with a picosecond 755 nm Alexandrite laser displaying continued marked resolution after cessation of treatment, without recurrence for 5 years.
Case Report
A thirty-five-year-old Asian woman with a bluish-gray confluent pigmentation along the right V1 distribution presented for diagnosis and treatment. Six treatments with a 750-picosecond pulse duration 755-nm alexandrite laser were performed, with one session every 2 weeks over 10 weeks. Patient was instructed to use topical sunscreen with zinc oxide >11% and topical healing creams. The patient experienced 8/10 pain with the first treatment session that decreased to 2/10 with pre-application of topical anesthetic cream (benzocaine 20%/ lidocaine 4%/ tetracaine 1%) 30 minutes prior to each session. Local skin reactions included temporary erythema and mild transient hyperpigmentation but no hypopigmentation. 
The hyperpigmentation decreased progressively but with persistent central blue-black pigmentation.Treatment was terminated when the patient moved away. When the patient was seen 1 year later, the nevus of Ota had resolved completely and the patient reported continued improvement for the 6 months after the last laser session until full clearance. The only continued maintenance treatment was usage of topical sunscreen with 11% zinc oxide. 
Bibliography
Picosecond lasers rely on photomechanical effects rather than photothermal. In contrast to nanosecond-domain Q-switched lasers, picosecond-domain lasers have a pulse width shorter than the stress relaxation time of dermal dendritic melanocytes and melanophages⁵. 
Mechanical stress generated within a very short period of time results in stress lock-in causing rise in pressure and fracture of the target particle and photoacoustic destruction of the particle, with a minimal photothermal component. The bursts of energy have been speculated to break down the melanin granules and melanophages, with clinical resolution occurring as macrophages carry away the fractured particles even after cessation of laser sessions⁴. 
This case report of delayed but persistent clinical resolution of a nevus of Ota validates theories on how picosecond lasers achieve clinical response through photomechanical effects followed by immunologic response.

Delayed Cessation but Long-term Resolution of Nevus of Ota After Picosecond 755-nm Alexandrite Laser Treatments

Artificial Intelligence (AI) systems like ChatGPT are increasingly explored for diagnostic purposes, particularly as more people may turn to these tools for self-diagnosis of skin conditions. This study evaluates ChatGPT-4 Turbo and ChatGPT-4 Omni (ChatGPT-4O) using the HAM10K dermatoscopic image dataset to classify 500 melanoma and 500 non-melanoma cases, with an additional 1,000 non-melanoma images to test false-positive rates. ChatGPT-4O achieved 57.7% accuracy (95% CI: 54.7%-60.8%) in identifying melanoma, while ChatGPT-4 Turbo had 54.6% accuracy (95% CI: 51.5%-57.7%). Both models showed high sensitivity but low specificity for melanoma diagnosis. For non-melanoma lesions, ChatGPT-4O’s accuracy was 6.56% (95% CI: 4.94%-8.18%), improving to 25.25% (95% CI: 22.55%-27.95%) when binary prompts were used. ChatGPT exhibited a tendency to conservatively classify lesions as melanoma, with explicit prompts improving performance. Despite these gains, the models’ diagnostic accuracy remains inadequate compared to specialized neural networks, suggesting that ChatGPT is not yet reliable for autonomous skin cancer diagnosis, even as more people may seek to use it for self-assessment.

Evaluating the Capability & Accuracy of CHATGPT’s Newest Models in Diagnosing between Melanoma and Non-Melanoma Lesions

Background
Melanoma, an invasive and potentially fatal form of skin cancer, is estimated to account for 5.0% of new cancer cases and 1.4% of cancer-related deaths in 2024 alone.2 Survival rates are closely linked to the stage at detection, with thicker tumors at initial diagnosis associated with reduced overall survival rate.3,4 Increased distance to healthcare providers creates barriers to early detection. Moreover, disparities in sun exposure and healthcare access between rural and urban populations underscore the need for targeted interventions to address these inequities. This review aims to bridge the knowledge gap regarding the relationship between rurality or distance to health providers with melanoma staging at detection, informing policies and interventions to improve outcomes in at-risk populations.
Methods
A search was conducted of the PubMed and Embase databases, following the Preferred
Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.23 The studies included were those that compared melanoma staging or Breslow thickness in rural areas to urban areas as well as studies doing the same comparison with distance to healthcare providers. 
Results
In this review, six cross-sectional and seven retrospective cohort studies were included, with international and U.S.-based studies represented. The scopes of these studies were hospital-wide, regional, and countrywide, with samples mainly consisting of all patients of the specified region with a diagnosis of primary melanoma. Most studies utilized population-based cancer registry data, while hospital-wide studies relied on electronic health records.
Studies examining the influence of rurality on melanoma staging and Breslow thickness yielded inconclusive findings, largely due to statistically insignificant results in related papers. However, consistent results were reported in studies evaluating the impact of distance from the provider on staging and tumor thickness at initial diagnosis. Increased distance to the provider is shown to have a significantly positive correlation with advanced staging and thickness. However, the limited sample representation poses the risk of biases affecting the reliability of such conclusions.
Conclusion
This review highlights the critical impact of healthcare accessibility on melanoma outcomes, particularly emphasizing the influence of distance to healthcare providers over rurality in determining Breslow thickness and tumor stage at initial diagnosis. The findings across studies evaluating provider distance underscore the necessity of reducing geographic barriers to dermatological services to improve early detection and management of melanoma. This reinforces the importance of ensuring equitable access to dermatological services regardless of region.

Geospatial Impacts on Melanoma Stage at Initial Diagnosis - A Systematic Review

Background: Psoriasis is one of the most prevalent chronic inflammatory skin conditions; however, its effects span much farther than its cutaneous manifestations. This study aims to assess the impact of biologic treatments on the development of depressive comorbidities in patients with psoriasis.

Methods: A retrospective chart analysis with data from TriNetX was performed for patients after propensity matching on TNF-α inhibitors (Cohort A), IL-17 inhibitors (Cohort B), and IL-23 + IL-12/23 inhibitors (Cohort C).

Results: All comparator groups showed a statistically significant decrease in new onset MDD, new onset DE, and new prescription of antidepressants. The risk ratios for both new onset MDD and DE, as well as odds ratio for new antidepressant prescription, respectively, were as follows: for Cohort A, 1.857 (CI: 1.233-2.797), 1.416 (CI: 1.176-1.705), 1.169 (CI: 1.031, 1.326); Cohort B, 2.636 (CI: 1.32-5.265), 2.35 (CI: 1.63-3.387), 1.169 (CI: 1.031, 1.326); Cohort C, 2.586 (CI: 1.687-3.964), 2.489 (CI: 1.965-3.154), 1.975 (CI: 1.71, 2.281.

Limitations: The TriNetX database has inherent limitations based on diagnosis codes and lack of sufficient data on cutaneous response.

Conclusion: Our study provides compelling evidence that biologic therapies for psoriasis, including IL-17, IL-12/23, IL-23, and TNF-𝛼 inhibitors, significantly reduce the risk of new diagnoses of MDD, new depressive episodes in patients, as well as lower the odds of starting a new prescription of antidepressant.

Impact of biologic treatments on the development of depressive comorbidities in patients with psoriasis

Abstract Title
Investigating the Association Between Ozempic Use and Psoriasis: An Analysis of FDA Adverse Event Reporting System Data from 2019-2024.


Background
GLP-1 agonists, including Ozempic, are prescribed to treat type 2 diabetes. While it is used for blood glucose control, the added advantage of Ozempic is weight reduction in patients with and without diabetes; because of this, its usage has increased over the years and has run into a shortage issue. Even though Ozempic is very effective for weight reduction and diabetes management, there have been cases described with adverse events, including psoriasis. This study aims to investigate a potential association between using Ozempic and psoriasis as an adverse event by analyzing cases of reported adverse events from the FDA Adverse Event Reporting System from 2019-2024.

Methods
In the FAERS database, the search terms "Ozempic" and "psoriasis" were used to identify reported cases of psoriasis in patients treated with Ozempic from 2019 to 2024. Non-plaque psoriasis variants, including pustular, guttate, and erythrodermic psoriasis, were excluded during data retrieval. Descriptive statistics, including Chi-Square tests, correlation analysis, and trend visualizations, were used to analyze case counts, age, gender, and severity. 

Results
In the FAERS database, from 2019 to June 2024, a total of 20 cases of psoriasis associated with Ozempic use were identified. Most cases lacked specified age data. The gender distribution was nearly equal, with 10 cases in males, 9 in females, and 1 with unspecified gender. Hospitalization was reported in one case. Statistical analysis using a Chi-Square test revealed no significant association between age, gender, and the development of psoriasis (χ² = 4.52, p = 0.34, dof = 4). A statistically significant association between Ozempic use and the development of psoriasis was observed (χ² = 5.75, p = 0.026, dof = 1). A trend analysis signified a slight increase in psoriasis cases over time, with the highest reported cases occurring in 2023. However, the correlation was weak (r = 0.147).


Conclusion
The study's findings imply that Ozempic use may be related to the development of psoriasis. However, the study is significantly limited by its small sample size, lack of detailed patient demographics, and potential reporting biases. Furthermore, confounding factors, such as the use of other medications or comorbid conditions, were not analyzed, further limiting the study’s initial findings. Additionally, to validate our study's preliminary findings and understand the potential biological mechanism involved in Ozempic leading to psoriasis, more extensive, controlled studies are required. The studies can help improve patient management strategies and risk assessment for Ozempic treatment.
