Background Current treatment paradigms recommend surgical intervention when conventional medical management proves ineffective in resolving chronic rhinosinusitis with nasal polyposis. Objectives To assess and compare the efficacy of dupilumab and functional endoscopic sinus surgery (FESS) for the treatment of chronic rhinosinusitis with nasal polyp (CRSwNP) over time. Methods Studies comparing CRSwNP patients who received dupilumab with those who underwent FESS were included. Outcome measures included the nasal congestion score (NCS), Sino-nasal Outcome Test-22 (SNOT-22), University of Pennsylvania Smell Identification Test-40 (UPSIT-40), and nasal polyp score (NPS). The risk of bias was evaluated using the Newcastle-Ottawa Scale. Results A total of 4 studies with 724 participants were included. The dupilumab group had a superior NCS, but an inferior NPS, compared to the FESS group during the follow-up period. The SNOT-22 score of the dupilumab group was inferior to that of the FESS group until 6 months posttreatment, but the scores were similar at around 1 year. A similar trend was observed for the UPSIT-40 score, but the score of the dupilumab group was higher at around 1 year. Conclusion Functional endoscopic sinus surgery was more effective than dupilumab for several months after treatment. However, at 1 year after treatment, the effects of the 2 treatments became similar, with greater olfactory improvement seen in the dupilumab group.

Abstract Objective To identify and disseminate research priorities for the headache field that should be areas of research focus during the next 10 years. Background Establishing research priorities helps focus and synergize the work of headache investigators, allowing them to reach the most important research goals more efficiently and completely. Methods The Headache Research Priorities organizing and executive committees and working group chairs led a multistakeholder and international group of experts to develop headache research priorities. The research priorities were developed and reviewed by clinicians, scientists, people with headache, representatives from headache organizations, health‐care industry representatives, and the public. Priorities were revised and finalized after receiving feedback from members of the research priorities working groups and after a public comment period. Results Twenty‐five research priorities across eight categories were identified: human models, animal models, pathophysiology, diagnosis and management, treatment, inequities and disparities, research workforce development, and quality of life. The priorities address research models and methods, development and optimization of outcome measures and endpoints, pain and non‐pain symptoms of primary and secondary headaches, investigations into mechanisms underlying headache attacks and chronification of headache disorders, treatment optimization, research workforce recruitment, development, expansion, and support, and inequities and disparities in the headache field. The priorities are focused enough that they help to guide headache research and broad enough that they are widely applicable to multiple headache types and various research methods. Conclusions These research priorities serve as guidance for headache investigators when planning their research studies and as benchmarks by which the headache field can measure its progress over time. These priorities will need updating as research goals are met and new priorities arise.

Chronic kidney disease (CKD) patients can benefit from personalized education on lifestyle and nutrition management strategies to enhance healthcare outcomes. The potential use of chatbots, introduced in 2022, as a tool for educating CKD patients has been explored. A set of 15 questions on lifestyle modification and nutrition, derived from a thorough review of three specific KDIGO guidelines, were developed and posed in various formats, including original, paraphrased with different adverbs, incomplete sentences, and misspellings. Four versions of AI were used to answer these questions: ChatGPT 3.5 (March and September 2023 versions), ChatGPT 4, and Bard AI. Additionally, 20 questions on lifestyle modification and nutrition were derived from the NKF KDOQI guidelines for nutrition in CKD (2020 Update) and answered by four versions of chatbots. Nephrologists reviewed all answers for accuracy. ChatGPT 3.5 produced largely accurate responses across the different question complexities, with occasional misleading statements from the March version. The September 2023 version frequently cited its last update as September 2021 and did not provide specific references, while the November 2023 version did not provide any misleading information. ChatGPT 4 presented answers similar to 3.5 but with improved reference citations, though not always directly relevant. Bard AI, while largely accurate with pictorial representation at times, occasionally produced misleading statements and had inconsistent reference quality, although an improvement was noted over time. Bing AI from November 2023 had short answers without detailed elaboration and sometimes just answered “YES”. Chatbots demonstrate potential as personalized educational tools for CKD that utilize layman’s terms, deliver timely and rapid responses in multiple languages, and offer a conversational pattern advantageous for patient engagement. Despite improvements observed from March to November 2023, some answers remained potentially misleading. ChatGPT 4 offers some advantages over 3.5, although the differences are limited. Collaboration between healthcare professionals and AI developers is essential to improve healthcare delivery and ensure the safe incorporation of chatbots into patient care.

Abstract Gastric adenocarcinoma (GAC) is the fourth leading global cause of cancer mortality and leading infection-associated cancer. High-incidence regions of GAC include Latin America and Eastern Asia. Immigrants from high-incidence regions maintain their GAC risk. GAC is a major U.S. cancer disparity, and its incidence rates are 2 to 10 times higher in non-White populations. Emerging guidelines recommend 3-year surveillance endoscopy for patients with high-risk gastric premalignant conditions (GPMC). Clinical trials of GPMC chemoprevention agents are lacking. We conducted a NCI Division of Cancer Prevention–funded, phase II placebo-controlled chemoprevention trial in patients with GPMCs (atrophic gastritis and intestinal metaplasia) with a highly bioavailable preparation of curcuminoids (Meriva). The trial sites in Puerto Rico and rural Honduras had important characteristics: (i) representative Caribbean and Mesoamerican populations, linked to large U.S. immigrant populations; (ii) high prevalence of Helicobacter pylori infection and GPMCs; (iii) the absence of turmeric and curcuminoids in local diets; and (iv) proven bidirectional collaboration with U.S. academic institutions. H. pylori–negative patients with GPMCs were randomized to the study drug (500 mg po bid) or placebo for 180 days (NCT02782949), with primary outcomes based upon histologic parameters. Principal study challenges included (i) an international regulatory environment; (ii) research infrastructure strengthening, particularly in Central America; (iii) participant recruitment in Honduras, wherein only 10% to 15% are H. pylori negative; (iv) the COVID-19 pandemic; and (v) natural disasters (three hurricanes). There were no losses to follow-up related to the pandemic or natural disasters. In conclusion, the south–south partnership provides a model for chemoprevention and translational studies in Latino populations with prevalent cancers, such as GAC.

AbstractCentral venous catheters are among the most used medical devices in hospitals today. Despite advances in modern medicine, catheter infections remain prevalent, causing significant morbidity and mortality worldwide. Here, SteriGel is reported, which is a multifunctional hydrogel engineered to prevent and treat central line‐associated bloodstream infections (CLABSI). The mechanical properties of SteriGel are optimized to ensure appropriate gelation kinetics, bio‐adhesiveness, stretchability, and recoverability to promote durability upon application and to provide persistent protection against infection. In vitro assays demonstrated that SteriGel exhibits long‐term antimicrobial efficacy and has bactericidal effects against highly resistant patient‐derived pathogens known to be frequently associated with CLABSI. SteriGel outperformed Biopatch, which is a clinically used device for CLABSI, in ex vivo cadaver studies that simulate clinical scenarios. Furthermore, SteriGel has biocompatible, pro‐healing, and anti‐inflammatory properties in vitro and in a rat subcutaneous injection model, suggesting a potential synergistic effect in the prevention and treatment of CLABSI. SteriGel is a multifunctional adherent biomaterial with potent antimicrobial effects for sustained sterility while promoting healing of the catheter incision site to protect against infection.

Abstract Advanced‐stage liver cancers are associated with poor prognosis and have limited treatment options, often leading the patient to hospice care. Percutaneous intratumoral injection of anticancer agents has emerged as a potential alternative to systemic therapy to overcome tumor barriers, increase bioavailability, potentiate immunotherapy, and avoid systemic toxicity, which advanced‐stage cancer patients cannot tolerate. Here, an injectable OncoGel (OG) comprising of a nanocomposite hydrogel loaded with an ionic liquid (IL) is developed for achieving a predictable and uniform tumor ablation and long‐term slow release of anticancer agents into the ablation zone. Rigorous mechanical, physiochemical, drug release, cytotoxicity experiments, and ex vivo human tissue testing identify an injectable version of the OG with bactericidal properties against highly resistant bacteria. Intratumoral injection of OG loaded with Nivolumab (Nivo) and doxorubicin (Dox) into highly malignant tumor models in mice, rats, and rabbits demonstrates enhanced survival and tumor regression associated with robust tissue ablation and drug distribution throughout the tumor. Mass cytometry and proteomic studies in a mouse model of colorectal cancer that often metastasizes to the liver indicate an enhanced anticancer immune response following the intratumoral injection of OG. OG may augment immunotherapy and potentially improve outcomes in liver cancer patients.

AbstractBackgroundDespite optimal medical therapy and cardiac resynchronization therapy (CRT), significant functional mitral regurgitation (MR) persisted in 30% of the patients and labeled as CRT nonresponders.AimsWe sought to study the impact of transcatheter edge‐to‐edge repair (TEER) in patients with symptomatic grade III and IV functional MR despite CRT.MethodsA retrospective analysis was conducted of all patients who had prior CRT for at least 6 months and underwent TEER for significant residual functional MR (grade ≥3) and symptomatic heart failure (HF) at our institution. The primary outcomes were the change in New York Heart Association classification (NYHA), MR grade, echo parameters, and NT‐ProBNP from baseline to 1‐year post‐procedure.ResultsA total of 28 patients were identified, mean age of 73 ± 6.7 years and 89% males. Procedure success was achieved in all patients. At 1‐year follow‐up, patients had lower MR grade (median 2, IQR 1 [1,2] vs. 4, IQR 1 [3,4]; p < 0.001), NYHA class (median 2, IQR 1 [2,3] vs. 3, IQR 1 [3,4]; p < 0.001), and NT‐ProBNP (7658 ± 11322 vs. 3760 ± 4431; p = 0.035) compared to before the TEER procedure. The left ventricular end‐diastolic volume (255 ± 59 vs. 244 ± 66 mm; p = 0.016) and the right ventricular systolic pressure (52 ± 14 mmHg vs. 37 ± 13 mmHg, <0.001) decreased.ConclusionPatients who remain symptomatic after CRT with severe functional MR had improved functional status and MR grade at 1‐year following TEER. There was a signal toward reverse remodeling.

Patients with inflammatory bowel diseases (IBDs) may require solid organ transplants (SOTs) for multiple reasons, making its prevalence slightly higher than the general population. Although immunosuppression used in SOT may help control IBD-related inflammation, many patients still require additional immunosuppressive medications. We aim to assess the effectiveness and safety of the combination of SOT-related immunosuppression and IBD medications in patients with liver, kidney, or heart transplantation. We conducted a clinical review using PubMed, Scopus, MEDLINE, Embase, and Google Scholar databases for our search. We included data from systematic reviews, meta-analyses, case series, and case reports to assess the safety, effectiveness, and side effect profile of immunomodulators, biologic therapies, and small molecules in patients with SOT. Our review encompassed 25 liver, 6 kidney, and 1 heart transplant studies involving patients with IBD. Common liver transplant immunosuppressants included tacrolimus, mycophenolate mofetil, cyclosporine, and steroids. Anti-TNF agents, widely used in all SOT types, showed no significant safety issues, though infections and malignancies were noted. Patients with liver transplant on tacrolimus responded well to anti-integrins and ustekinumab without major complications. For kidney transplants, cyclosporine and tacrolimus were prevalent, and their combination with anti-TNF or ustekinumab was generally safe, with rare reports of malignancy or infection. Hence, the use of anti-TNF, anti-integrin agents, and ustekinumab appears to be safe in patients with SOT, regardless of their transplant related immunosuppression. More studies are needed in patients with kidney and heart transplants and in patients treated with small molecules for their IBD.
