Variable Tracer Avidity and Interlesional Heterogeneity on 18F-FDG, 68Ga-DOTATATE, and 68Ga-DOTA-FAPi-04 PET/CT Imaging in a Single Individual Patient With Progressive Metastatic Medullary Thyroid Carcinoma.

In medullary thyroid carcinoma (MTC), distant metastases have few therapeutic options with low success rates and substantial toxicity in many patients, warranting exploration of alternate systemic treatments with fewer adverse effects. The fibroblast activation protein inhibitor (FAPI)-based PET/CT opens new avenues for several cancers, including MTC. A case of MTC with varying tracer avidity and interlesional heterogeneity on 18F-FDG, 68Ga-DOTATATE, and 68Ga-DOTA-FAPI-04 PET/CT imaging is presented. 68Ga-DOTA-FAPI-04 PET/CT exhibited superior efficacy in terms of visualization of metastatic soft tissue, lymph nodal, and skeletal lesions, with enhanced target-to-background ratio compared with the other two, facilitating the detection of these lesions, thereby demonstrating the potential for theranostic translation.

Emerging Biologic Therapies for the Treatment of Atopic Dermatitis.

Atopic dermatitis (AD) is a prevalent inflammatory skin disease having a significant impact on patients' quality of life. Conventional treatments, including topical therapies and systemic immunosuppressants, often have limited efficacy and long-term safety concerns. Emerging biologic therapies target specific immune pathways implicated in AD pathogenesis, offering new therapeutic options in a disease known for its complex immune pathomechanisms. This review focuses on novel biologics under investigation, particularly those targeting specific immune pathways such as interleukin-4 (IL-4), IL-13, IL-22, IL-31, thymic stromal lymphopoietin (TSLP), and OX40-OX40L axis. Interleukin-4 and IL-13 inhibitors aim to reduce Th2-driven inflammation, while IL-22 inhibitors focus on restoring skin barrier function. Interleukin-31 inhibitors help alleviate pruritus, a major symptom in AD. OX40-OX40L pathway inhibitors can selectively suppress the activity of pathogenic T cells, without inducing significant immunosuppression. Bispecific antibodies targeting both IL-4 and IL-31 pathways are emerging as potential dual-action treatment for AD. Thymic stromal lymphopoietin inhibitors offer a novel strategy to control inflammation. While many of these therapies offer promising safety and efficacy profiles, long-term studies and real-world data are essential to confirm their lasting impact. This review highlights the potential of these emerging systemic therapies to continue transforming AD management and improve patient outcomes.

Navigating new norms: Addiction specialists' perspectives on opioid use disorder treatments and policy challenges in the fentanyl era.

Amidst increasing opioid-related overdoses in the USA, opioid use disorder (OUD) treatment has seen few novel treatments emerge. High-potency synthetic opioids (HPSOs) have altered clinical approaches, prompting evaluation of existing medications for opioid use disorder (MOUD) and interest in slow-release oral morphine (SROM) as another therapeutic option. Here we survey addiction specialists on the influence of HPSOs on clinical practice, views on current MOUD regulations, and openness to novel therapies such as SROM. Anonymous, online survey conducted at a national conference of addiction specialists (N = 91). Pearson χ2 tests and Fisher's exact tests to compare respondent characteristics. Approximately 89% of respondents (N = 91) acknowledge that HPSOs shifted addiction treatment in recent years, with 86% modifying their MOUD prescribing accordingly. Moreover, 84% report having patients who could benefit from other full opioid agonists beyond methadone for OUD management. Many report off-label prescribing of full agonist opioids other than methadone for withdrawal symptoms or initiating MOUD. Eighty percent reported being in favor of incorporating SROM as a third-line monotherapy for OUD. This sample of addiction specialists supports innovative alternatives for MOUD in the USA to combat the challenges posed by fentanyl and related HPSOs. Future work should further addiction specialists' opinions on barriers to OUD treatment and exploration of these international strategies in the USA. This appears to be the first study exploring addiction specialists' perspectives on regulatory barriers to OUD treatment and their willingness to uptake internationally adopted strategies such as SROM.

Neurology of Aging : adapting neurology provision for an aging population.

Background Over the past few decades, advances in neurology of aging have been considerable and have led to a better understanding of the science of age-related neurological disorders. Likewise, it changed the perception of classical neurology practice, research and the way of looking at age-related conditions. Neurological disorders are the most frequent cause of major disability in the elderly and account for almost half of the incapacitation occurring beyond age 65 and more than 90% of serious dependency. However, a number of neurological changes occur also in the absence of a specific disease, making the assessment and management of neurological complaints and findings a specific expertise. Summary Maximizing success in clinical care of the elderly requires expertise in geriatric neurology, which includes an understanding of current research regarding aging and age-related neurological dysfunctions, and the ability to work with other geriatric health care providers. Although current therapies for neurodegenerative diseases mainly offer symptomatic relief without slowing progression, the landscape is evolving. Biomarkers of pathology and neuroimaging have continued to develop, with a significant impact on diagnosis and treatment. These advances have helped to improve our knowledge of disease pathophysiology but also disease stages, guiding symptomatic monitoring, and possible therapeutic options at a pre-symptomatic stage. Key Messages Neurological disorders are a leading cause of major disability and dependency in the elderly, underscoring the need for expertise in geriatric neurology for effective clinical care of this population. Although current therapies for neurodegenerative diseases primarily provide symptomatic relief without slowing disease progression, advancements in biomarkers and neuroimaging are significantly evolving. These advancements enhance our understanding of disease pathophysiology and stages, guiding symptomatic monitoring and potential therapeutic options at a pre-symptomatic stage. As knowledge about age-associated conditions is steadily rising and geriatric medicine gains further recognition, this article argues for a new focus on the role of neurologists in geriatric medicine, emphasizing the importance of integrating current research and collaborative care approaches in the management of elderly patients.

État des lieux de la prise en charge de l’orbitopathie dysthyroidïenne modérée à sévère active en France à partir de 28 centres experts métropolitains

Introduction: This study investigates the management of Graves’orbitopathy (GO) in France, at 26 university medical centers (CHU) as well as the Rothschild Foundation and the Quinze-Vingts national eye hospital in Paris.Methods: The 28 metropolitan university medical centers were contacted by telephone or e-mail. The authors devised a 5-item questionnaire that explored the scheduling of multidisciplinary meetings, the existence or lack of a dedicated Graves’ consultation service, the place of hospitalization, and first- and second-line treatments.Results: 89% of hospital departments had a dedicated service for patients with GO, with 36% organizing multidisciplinary meetings. Intravenous corticosteroid therapy is still used as first-line treatment, while mycophenolate is used much less (14.3%), despite the new EUGOGO (European Group on Graves' orbitopathy) 2021 recommendations. For second-line treatment, tocilizumab is most commonly used (64%). Teprotumumab is available in France only on a compassionate basis, and its use is limited (18%).Conclusion: This study highlights the variability in practices and the importance of a multidisciplinary approach, while calling for national standardization of practices. Despite disparities in the application of recommendations, the emergence of second-line treatments such as tocilizumab and teprotumumab indicates a steady evolution in therapeutic options, although obstacles in terms of accessibility and cost remain.

Single-Atom Catalysts with Isolated Cu1-N4 Sites for Atopic Dermatitis Cascade Catalytic Therapy via Activating PPAR Signaling.

Atopic dermatitis (AD) is one of the most common allergic skin disorders affecting over 230 million people worldwide, while safe and efficient therapeutic options for AD are currently rarely available. Reactive oxygen species (ROS) accumulation plays a key role in AD's disease progression. Therefore, a novel single-atom catalyst is designed with isolated Cu1-N4 sites anchored on carbon support (Cu1-N4 ISAC), featuring triple antioxidant enzyme-mimicking activities, for efficient AD cascade catalytic therapy (CCT). The excellent superoxide dismutase (SOD)-, glutathione peroxidase (GPx)-, and ascorbate peroxidase (APx)-like activities of Cu1-N4 ISACs enable the sequential conversion of O2•- to H2O2 and then to harmless H2O, thereby protecting keratinocytes from oxidative stress damage. Notably, two novel experimental methods are developed to directly prove the SOD-GPx and SOD-APx cascade catalytic activities for the first time. In vivo experiments show that Cu1-N4 ISACs are more potent than a recommended typical medicine (halcinonide solution). Additionally, RNA sequencing and bioinformatic analysis reveal that Cu1-N4 ISACs reduce inflammation and inhibit ROS production by activating PPAR signaling, which is aberrantly reduced in AD. Therefore, the synthesized catalytic medicine offers an alternative to alleviate AD and has the potential to serve as PPAR agonists for treating similar diseases.

Angiotensin-converting enzyme inhibitors: a therapeutic option for controlling blood pressure associated with delayed cognitive processing speed.

Antihypertensive treatment (AT) is essential for preventing hypertension-related cognitive decline. The goals of this observational study were to compare cognitive performance (CP) between non-hypertensive (NH) volunteers and hypertensive patients and to evaluate the correlation between CP and antihypertensive drugs (AHD). Three groups were constituted: NH (n = 30) [group 1], hypertensive with systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) < 90 mmHg (n = 54) [group 2] and hypertensive with SBP ≥ 140 or DBP ≥ 90 (n = 31) [group 3]. To analyze the cognitive domains, a neuropsychological battery was applied and the raw performance values in these tests were transformed into z-scores. The domain was considered impaired if it presented a z-score below -1.5 SD. Compared to group 1, both groups of hypertensive were older (51 [ ± 12] years) and showed a worse CP in episodic memory (p = 0.014), language (p = 0.003) and processing speed (PS) [p = 0.05]. Angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB) were the most used AHD (46.3%, p = 0.01 [group 2] and 64.5%, p = 0.005 [group 3]) and showed correlations with PS. Linear regression models revealed a negative association of PS with the use of ACEi (β = -0.230, p = 0.004), but not with the use of ARB (β = 0.208, p = 0.008). The effect of AT on cognition appears to go beyond the search for lower blood pressure targets and also includes the mechanism of action of AHD on the brain, so that additional benefits may possibly be achieved with simple adaptations in the treatment regimen, particularly in patients without clinically manifest cognitive impairment.

From soil to clinic: current advances in understanding Coccidioides and coccidioidomycosis.

SUMMARYCoccidioides immitis and Coccidioides posadasii are fungal pathogens that cause systemic mycoses and are prevalent in arid regions in the Americas. While C. immitis mainly occurs in California and Washington, C. posadasii is widely distributed across North and South America. Both species induce coccidioidomycosis (San Joaquin Valley fever or, more commonly, Valley fever), with reported cases surging in the United States, notably in California and Arizona. Moreover, cases in Argentina, Brazil, and Mexico are on the rise. Climate change and environmental alterations conducive to Coccidioides spp. proliferation have been recently explored. Diagnostic challenges contribute to delayed treatment initiation, compounded by limited therapeutic options. Although antifungal drugs are often effective treatments, some patients do not respond to current therapies, underscoring the urgent need for a vaccine, particularly for vulnerable populations over 60 years old relocating to endemic areas. Despite recent progress, gaps persist in the understanding of Coccidioides ecology, host immune responses, and vaccine development. This review synthesizes recent research advancements in Coccidioides ecology, genomics, and immune responses, emphasizing ongoing efforts to develop a human vaccine.

Peripheral blood lymphocyte subpopulations as predictive biomarkers for first-line programmed death 1 inhibitors efficacy in esophageal squamous cell carcinoma: A retrospective study

Esophageal cancer (EC) poses a significant global health burden, necessitating effective treatment strategies. Immune checkpoint inhibitors have emerged as a promising therapeutic option for EC, but the identification of predictive biomarkers remains crucial for optimizing patient outcomes. We conducted a retrospective analysis of medical records from advanced esophageal squamous cell carcinoma patients treated with first-line programmed death 1 inhibitors. Peripheral blood lymphocyte subpopulations were evaluated using flow cytometry, while hematological tests provided data on neutrophil, lymphocyte, and monocyte counts. Cox regression and logistic regression analyses were employed to explore the association between lymphocyte subpopulations, baseline characteristics, and progression-free survival (PFS). Among the 100 initially included patients, 70 met eligibility criteria. Multivariate Cox regression analysis revealed a significant association between high CD16+CD56+ lymphocyte proportions and longer PFS, independent of other clinical variables. Similarly, a high CD4+/CD8+ ratio was correlated with prolonged PFS. Kaplan–Meier survival curves supported these findings. Logistic regression analysis indicated no significant differences in the CD4+/CD8+ ratio and CD16+CD56+ lymphocytes concerning baseline characteristics, suggesting their potential as independent prognostic markers. Our study highlights the predictive value of peripheral blood CD16+CD56+ lymphocytes and the CD4+/CD8+ ratio for the efficacy of programmed death 1 inhibitors in advanced esophageal squamous cell carcinoma patients. These findings underscore the importance of peripheral blood biomarkers in guiding personalized immunotherapy strategies and improving outcomes for EC patients.

The genomic and transcriptomic landscape of metastastic urothelial cancer

Metastatic urothelial carcinoma (mUC) is a lethal cancer, with limited therapeutic options. Large-scale studies in early settings provided critical insights into the genomic and transcriptomic characteristics of non-metastatic UC. The genomic landscape of mUC remains however unclear. Using Whole Exome (WES) and mRNA sequencing (RNA-seq) performed on metastatic biopsies from 111 patients, we show that driver genomic alterations from mUC were comparable to primary UC (TCGA data). APOBEC, platin, and HRD mutational signatures are the most prevalent in mUC, identified in 56%, 14%, and 9% of mUC samples, respectively. Molecular subtyping using consensus transcriptomic classification in mUC shows enrichment in neuroendocrine subtype. Paired samples analysis reveals subtype heterogeneity and temporal evolution. We identify potential therapeutic targets in 73% of mUC patients, of which FGFR3 (26%), ERBB2 (7%), TSC1 (7%), and PIK3CA (13%) are the most common. NECTIN4 and TACSTD2 are highly expressed regardless of molecular subtypes, FGFR3 alterations and sites of metastases.

Corneal stromal lenticule transplantation for the treatment of congenital optic disc pit maculopathy : a case report and review

BackgroundCongenital optic disc pit (ODP) is a relatively uncommon congenital anomaly of the optic disc, which seriously affects the patient’s vision when combined with optic disc pit maculopathy(ODP-M). Currently, the treatment of ODP-M remains a clinical challenge and a focus of research.Case presentationA boy had a pit in the inferotemporal segment of the optic disc with ODP-M. Optical Coherence Tomography(OCT) showed ODP and serous retinal detachment. He was treated with pars plana vitrectomy(PPV), followed by Corneal Stromal Lenticule (CSL) sealing and C3F8 tamponade. In the end, significant anatomical improvement was achieved, and the Best Corrected Visual Acuity(BCVA) was improved.ConclusionsThe CSL transplantation may be a viable therapeutic option for improving ODP-M with stable anatomical and functional result. However, more cases and longer follow-up are needed to confirm the safety and effectiveness of the technology.

Apolipoproteins have a major role in cellular tumor dormancy in triple negative breast cancer: In-silico study

Triple-negative breast cancer (TNBC) lacks estrogen, progesterone, and human epidermal growth factor receptors and has a poor prognosis as it is resistant to chemotherapy. A new treatment option for this type of cancer may be by putting these malignant cells into dormancy. The oocyte’s embryonic milieu presents a unique tumor reversion microenvironment by inducing growth arrest and changing cells’ phenotypes. We conducted an in-silico study to determine the most likely oocyte extract (OE) proteins involved in inducing dormancy using HDock, CluPro, and molecular dynamic (MD) simulation. Results showed low energy scores for complexes between OE proteins and four surface markers: K1C14, CLD3, CLD4, and ITA6. Apolipoprotein A1 (APOA1) and Apolipoprotein C3 (APOC3) showed the highest stability and affinity with these four surface markers: K1C14, CLD3, CLD4, and ITA6. These proteins are involved in key tumor-related pathways such as angiogenesis, proliferation, apoptosis, and migration. This will pave the way for exploring novel therapeutic options to induce dormancy in TNBC cells.

Towards New Anti-inflammatory Agents: Design, Synthesis and Evaluation of Molecules Targeting XIAP-BIR2.

The X-chromosome-linked inhibitor of apoptosis protein (XIAP) plays a crucial role in controlling cell survival across multiple regulated cell death pathways and coordinating a range of inflammatory signalling events. The discovery of selective inhibitors for XIAP-BIR2, able to disrupt the direct physical interaction between XIAP and RIPK2, offer promising therapeutic options for NOD2-mediated diseases like Crohn's disease, sarcoidosis, and Blau syndrome. The objective of this study was to design, synthesize, and evaluate small synthetic molecules with binding selectivity to XIAP-BIR2 domain. To achieve this, we applied an interdisciplinary drug design approach and firstly we have synthesized an initial fragment library to achieve a first XIAP inhibition activity. Then using a growing strategy, larger compounds were synthesized and one of them presents a good selectivity for XIAP-BIR2 versus XIAP-BIR3 domain, compound 20c. The ability of compound 20c to block the NOD1/2 pathway was confirmed in cell models. These data show that we have synthesized molecules capable of blocking NOD1/2 signalling pathways in cellulo, and ultimately leading to new anti-inflammatory compounds.

Different diseases, different needs: Patient preferences for gene therapy in lysosomal storage disorders, a probabilistic threshold technique survey

BackgroundGene therapy is currently in development for several monogenetic diseases including lysosomal storage disorders. Limited evidence is available on patient preferences for gene therapy in this population. In this study, we compare gene therapy-related risk tolerance between people affected by three lysosomal storage diseases currently faced with different therapeutic options and prognoses.MethodsA survey including the probabilistic threshold technique was developed in which respondents were asked to choose between gene therapy and the current standard of care. The attributes included to establish participants’ risk tolerance were previously identified in focus groups of affected people or their representatives, namely: risk of mild side effects, severe side effects, the need for additional medication, and the likelihood of long-term effectiveness. The survey was distributed among people receiving outpatient care for type 1 Gaucher disease (good prognosis with current treatment options), Fabry disease (varying prognosis with current treatment options, XY-genotype on average more severely affected than XX), and parents representing people with severe forms of mucopolysaccharidosis type III A/B (poor prognosis, no disease-specific therapy available).ResultsA total of 85 surveys were completed (15 Gaucher disease respondents, 62 Fabry disease respondents (17 self-identifying male), eight parents of ten people with mucopolysaccharidosis type III). Disease groups with higher disease severity trended towards higher risk tolerance: Gaucher disease respondents were most cautious and predominantly preferred the current standard of care as opposed to MPS III representatives who were more risk tolerant. Respondents with Fabry disease were most heterogeneous in their risk tolerance, with male participants being more risk tolerant than female participants. Long-term effectiveness was the attribute in which respondents tolerated the least risk.ConclusionsPeople affected by a lysosomal storage disease associated with a poorer prognosis and less effective current treatment options trended towards more risk tolerance when choosing between gene therapy and the current standard of care. This study shows the importance of involvement of patient preferences before and during the development process of new treatment modalities such as gene therapy for rare diseases, to ensure that innovative therapies align with the wishes and needs of people affected by these diseases.

Emerging Thrombotic Disorders Associated with Virus-Based Innovative Therapies: From VITT to AAV Gene Therapy-Related Thrombotic Microangiopathy.

Gene therapy is a promising therapeutic approach for treating life-threatening disorders. Despite the clinical improvements observed with gene therapy, immune responses either innate or adaptive against the vector used for gene delivery, can affect treatment efficacy and lead to adverse reactions. Thrombotic microangiopathy (TMA) is a thrombosis with thrombocytopenia syndrome (TTS) characterized by microangiopathic hemolytic anemia, thrombocytopenia, and small vessel occlusion known to be elicited by several drugs, that has been recently reported as an adverse event of adeno-associated virus (AAV)-based gene therapy. TMA encompasses a heterogenous group of disorders, its classification and underlining mechanisms are still uncertain, and still lacks validated biomarkers. The identification of predictors of TMA, such as vector dose and patient characteristics, is a pressing need to recognize patients at risk before and after AAV-based gene therapy administration. This review aims to explore the literature on TMA associated with AAV-based gene therapy in the larger context of TMA (i.e., hemolytic-uremic syndrome, thrombotic thrombocytopenic purpura, and other drug-related TMAs). Considering the wide attention recently gained by another TTS associated with a non-gene therapy viral platform (adenovirus, AV COVID-19 vaccine), namely vaccine-induced immune thrombocytopenia and thrombosis (VITT), AAV gene therapy-related TMA mechanisms will be discussed and differentiated from those of VITT to avoid recency bias and favor a correct positioning of these two recently emerged syndromes within the heterogenous group of drug-related TTS. Finally, the review will discuss strategies for enhancing the safety and optimize the management of AAV-based gene therapy that is emerging as an efficacious therapeutic option for disparate, severe, and often orphan conditions.

Identification and evaluation of candidate COVID-19 critical genes and medicinal drugs related to plasma cells

The ongoing COVID-19 pandemic, caused by the SARS-CoV-2 virus, represents one of the most significant global health crises in recent history. Despite extensive research into the immune mechanisms and therapeutic options for COVID-19, there remains a paucity of studies focusing on plasma cells. In this study, we utilized the DESeq2 package to identify differentially expressed genes (DEGs) between COVID-19 patients and controls using datasets GSE157103 and GSE152641. We employed the xCell algorithm to perform immune infiltration analyses, revealing notably elevated levels of plasma cells in COVID-19 patients compared to healthy individuals. Subsequently, we applied the Weighted Gene Co-expression Network Analysis (WGCNA) algorithm to identify COVID-19 related plasma cell module genes. Further, positive cluster biomarker genes for plasma cells were extracted from single-cell RNA sequencing data (GSE171524), leading to the identification of 122 shared genes implicated in critical biological processes such as cell cycle regulation and viral infection pathways. We constructed a robust protein-protein interaction (PPI) network comprising 89 genes using Cytoscape, and identified 20 hub genes through cytoHubba. These genes were validated in external datasets (GSE152418 and GSE179627). Additionally, we identified three potential small molecules (GSK-1070916, BRD-K89997465, and idarubicin) that target key hub genes in the network, suggesting a novel therapeutic approach. These compounds were characterized by their ability to down-regulate AURKB, KIF11, and TOP2A effectively, as evidenced by their low free binding energies determined through computational analyses using cMAP and AutoDock. This study marks the first comprehensive exploration of plasma cells’ role in COVID-19, offering new insights and potential therapeutic targets. It underscores the importance of a systematic approach to understanding and treating COVID-19, expanding the current body of knowledge and providing a foundation for future research.

CAR-macrophage: Breaking new ground in cellular immunotherapy

Chimeric Antigen Receptor (CAR) technology has revolutionized cellular immunotherapy, particularly with the success of CAR-T cells in treating hematologic malignancies. However, CAR-T cells have the limited efficacy of against solid tumors. To address these limitations, CAR-macrophages (CAR-Ms) leverage the innate properties of macrophages with the specificity and potency of CAR technology, offering a novel and promising approach to cancer immunotherapy. Preclinical studies have shown that CAR-Ms can effectively target and destroy tumor cells, even within challenging microenvironments, by exhibiting direct cytotoxicity and enhancing the recruitment and activation of other immune cells. Additionally, the favorable safety profile of macrophages and their persistence within solid tumors position CAR-Ms as potentially safer and more durable therapeutic options compared to CAR-T cells. This review explores recent advancements in CAR-Ms technology, including engineering strategies to optimize their anti-tumor efficacy and preclinical evidence supporting their use. We also discuss the challenges and future directions in developing CAR-Ms therapies, emphasizing their potential to revolutionize cellular immunotherapy. By harnessing the unique properties of macrophages, CAR-Ms offer a groundbreaking approach to overcoming the current limitations of CAR-T cell therapies, paving the way for more effective and sustainable cancer treatments.

Treatment-Resistant Melasma Response to Oral Tranexamic Acid

Melasma, a common acquired hyperpigmentation disorder primarily affecting facial skin, poses significant therapeutic challenges due to the limited efficacy and potential side effects of available treatments. Tranexamic Acid (TXA), traditionally used for its hemostatic properties by inhibiting plasminogen activation, has emerged as a promising addition to protocols for treatment-resistant melasma. This study aims to evaluate the efficacy and safety of TXA in combination with Hydroquinone (HQ) and Kojic Acid (KA) in patients with treatment-resistant melasma. We present here a case series of fourteen patients with recurrent melasma refractory to common treatments who achieved successful outcomes with the addition of TXA to their treatment regimen. These patients received 650 mg of TXA in combination with 16% HQ and 6% KA. All patients exhibited a symmetrical reduction in their hyperpigmented patches following treatment and no significant adverse effects were reported. These cases contribute valuable input to the growing body of evidence on the use of TXA for melasma and the combination of treatments and dosing, suggesting its potential as a therapeutic option for this condition. Further research is warranted to explore the mechanisms by which TXA exerts its beneficial effects in melasma and to determine the optimal treatment protocols for achieving effective clinical outcomes.

Assessing Student and Patient Perspectives on Pharmacist Prescribed Hormonal Contraceptives

BackgroundIncreasing convenient, accessible, and cost effective contraceptive access is critically important. Two-thirds of US states permit pharmacists to prescribe hormonal contraceptives. Community pharmacies are ideal settings for patients to be offered contraceptive therapeutic options including hormonal contraceptives, emergency contraception (EC), and over-the-counter (OTC) oral contraception. ObjectiveThe objective of this study was to assess college student and community pharmacy patients’ perspectives on pharmacist prescribed hormonal contraceptives, likelihood of accessing contraceptives from a pharmacist, and perspectives regarding EC and OTC oral contraception. MethodsThe researchers conducted an observational study distributed to college students and patients accessing care at community-based pharmacies from October 2022 to February 2023. The survey population included those who were 18 years or older, English speaking, and recruited both in person and online. Survey questions assessed barriers to contraception access, perspectives towards pharmacist prescribed hormonal contraception, likelihood of receiving pharmacist prescribed hormonal contraception as well as EC and OTC oral contraception at the community pharmacy. Results from the pharmacist and clinician surveys were previously published, therefore this report will focus on the student and patient data. ResultsNinety-one percent of all respondents strongly agreed or agreed with pharmacist-prescribed hormonal contraception. Students and patients reported convenience, time saving, and money saving as reasons for obtaining from their pharmacist. In regard to EC, 36% reported having ever purchased from a pharmacy and 58% were extremely or somewhat likely to purchase OTC oral contraception. ConclusionsThe majority of students and community pharmacy patients surveyed in Rhode Island support pharmacist prescribed hormonal contraceptives. State-level policy advancements with reimbursement for services provide pharmacists an opportunity to provide contraceptive care for all people.
