Sepsis is a life-threatening disease characterized by a dysregulated immune response to infection, often leading to neuroinflammation. As a known immunomodulator, Maresin-1 (MaR1) may have potential applications in the treatment of sepsis-induced neuroinflammation, but its effects in this context are unknown. We used a mouse cecum ligation and puncture (CLP)-induced sepsis model and an in vitro lipopolysaccharide (LPS)-induced neuroinflammatory model of BV2 microglia. Expression of microglial cell markers (IBA1, CD11B, CD68, CD86 and CD206) and pro-inflammatory markers (iNOS and COX2) was assessed. The role of MaR1 in regulating the P38 MAPK pathway was explored using the P38 MAPK inhibitor SB203580. In the CLP model, an increased proportion of M1-type microglia was observed, and MaR1 was able to reverse it. However, the combination of SB203580 and MaR1 did not enhance the therapeutic effect compared to SB20580 alone. In vitro experiments, MaR1 inhibited LPS-induced P38 MAPK nuclear translocation and decreased the expression of pro-inflammatory markers such as iNOS and COX2. As with the animal results, no stacking effect could be obtained with the co-administration of SB203580 and MaR1. Our findings suggest that MaR1 attenuates sepsis-induced neuroinflammation mainly by inhibiting phosphorylation of P38 MAPK in microglial cells. This suggests that MaR1 may have a potential therapeutic role in the treatment of sepsis neuroinflammation., Competing Interests: Declarations.

This study investigated whether adjuvant treatments in stage III cutaneous melanoma (CM) influenced patterns of recurrence. Patients with primary (n = 1033) or relapsed CM (n = 350) who received adjuvant therapies with Nivolumab (N), Pembrolizumab (P), or Dabrafenib and Trametinib (D + T) were extracted from the prospective multicenter real-world skin cancer registry ADOReg. Endpoints were progression-free survival (PFS), distant metastasis-free survival (DMFS), organ-specific DMFS, and overall survival (OS). For primary cases, D + T indicated an improved PFS (1- and 2-year PFS: 90.9%; 82.7%) as compared to P (81.0%, 73.9%; p = .0208), or N (83.8%, 75.2%; p = .0539). BRAF-mutated(mut) CM demonstrated significantly lower PFS (p = .0022) and decreased DMFS (p = .0580) when treated with immune checkpoint inhibitor (ICI) instead of D + T. Besides, NRAS-mut CM tended to perform worse than wt CM upon ICI (PFS: p = .1349; DMFS: p = .0540). OS was similar between the groups. Relapsed cases showed decreased PFS, DMFS, and OS in comparison to primary (all: p < .001), without significant differences between the subgroups. Organ-specific DMFS was significantly altered for primary cases with bone (p = .0367) or brain metastases (p = .0202). In relapsed CM, the frequency of liver (D + T: 1.5%; P: 12%; N: 9%) and LN metastases (D + T: 1.5%; P: 12%; N: 10.2%) was significantly lower with adjuvant D + T than ICI. NRAS-mut CM showed increased recurrence in primary and relapsed cases. These data show that adjuvant D + T is superior to ICI in primary BRAF-mut CM., (© 2024 The Author(s).

Traf2- and Nck-interacting kinase (TNIK) has been identified as a promising therapeutic target for the treatment of fibrosis-driven diseases. Utilizing a structure-based drug design workflow, we developed a series of potent TNIK inhibitors that modulate the conformation of the gatekeeper Met105 side chain and access the TNIK back pocket. The lead optimization efforts culminated in the discovery of the recently reported compound 4 (INS018&#95;055), a novel TNIK inhibitor. This molecule demonstrated excellent activity in both enzymatic and cell-based assays, along with high selectivity in a kinome panel. Further, in vitro and in vivo preclinical studies revealed favorable in vitro and in vivo DMPK properties. Results from multiple cell-based and animal models proved that compound 4 exhibits considerable antifibrotic and anti-inflammatory efficacy. Currently, phase II clinical trials of compound 4 are underway for the treatment of idiopathic pulmonary fibrosis (IPF).

Treatment of onychomycosis includes topical and systemic agents. However, prolonged use of oral treatment could cause adverse effects and topical antifungal agents have limited penetration. To compare the clinical efficacy and the safety of fractional CO 2 laser combined with topical tioconazole nail solution versus Q-switched 1064 Nd: YAG laser in the treatment of fingernail onychomycosis. This randomized comparative clinical trial was conducted on 13 patients (47 nails) with fingernail onychomycosis. Patients were randomized to receive either fractional CO2 laser combined with topical tioconazole or Q-Switched Nd: YAG 1064 nm laser every 2 weeks for 3 months followed by a 1-month follow up assessment. Onychomycosis severity index (OSI) score, Dermatology life Quality Index (DLQI) score, patient satisfaction score, dermoscopic evaluation and KOH examination were used for assessment of improvement. OSI showed improvement after treatment in both arms (from 16.17 to 10.92 in fractional CO2 arm (p = 0.026) and 23.13 to 22.43 (p = 0.92)). When comparing both groups OSI score significantly reduced in the fractional CO2 laser combined with tioconazole more than the Q-switched laser group (p = 0.002). The mean DLQI score significantly improved in both groups but no statistically significant difference between the two groups. Significant improvement in patient satisfaction score was noted in both groups. Mycological cure using KOH examination was detected in both groups (44.4% in the CO2 group and 56.5% in the Q-switched group) with no significant difference (P value < 0.05). Ruin pattern keratosis found to be the most dermoscopic pattern to be associated with poor OSI score improvement. Fractional CO2 laser combined with topical tioconazole is more efficient in treatment of onychomycosis than Q-Switched Nd: YAG 1064 nm laser group as regards clinical improvement but both have comparable effect on mycological cure. Their use as adjuvant treatment rather than alone is recommended to ensure mycological cure in onychomycosis., Competing Interests: Declarations Ethical approval The study has been approved by the ethical committee of both the Department Scientific and Ethical Committee Boards of Kasr Alainy Faculty of Medicine, Cairo University.

Background: The high rates of the sustained virologic response 12 weeks after treatment (SVR12) in real world settings provoked the adoption of shortened courses of the costly direct-acting antivirals (DAAs) regimens. This study provides, to our knowledge, the first systematic review and meta-analysis for the efficacy of the shortened 8-week course of sofosbuvir (SOF) plus daclatasvir (DCV), the most accessible DAAs in the low-middle income countries (LMICs)., Methods: We performed a proportion meta-analysis to determine a reliable rate of SVR12 by pooling all studies that evaluated the results of the 8-week regimen of DCV + SOF. In addition, we applied sensitivity analyses using two imputation paradigms: a conservative approach, and a pragmatic approach to avoid overestimating the efficacy of the 8-week regimen in studies that followed a response-guided treatment (RGT) approach., Results: Six studies with a total of 159 patients were included. The pooled SVR12 rate ranged from 91 to 97% in the included scenarios. The pragmatic scenario showed that the pooled SVR12 was 97% (95% confidence interval (CI) 91%; 100%) with lower variability as assessed by the prediction interval. The conservative approach revealed an SVR12 of 93% (95% CI 84%; 95%)., Conclusion: The 8-week course of 60 mg DCV with SOF provided a comparable SVR12 to the standard 12-week regimen in treatment-naïve, non-HIV co-infected patients with a minimum estimated efficacy of 90%., (© 2024.

Skin cancer, notably melanoma, poses a significant global health burden, with rising incidence and mortality rates. While therapeutic advancements have improved outcomes, metastatic melanoma remains challenging to treat. This study aims to systematically review systemic treatment options for advanced melanoma, focusing on efficacy and safety in the first-line setting. Through a comprehensive search and meta-analysis of randomized controlled trials conducted from 2013 to 2023, 11 studies encompassing 2816 participants were analyzed. Treatment options included BRAF inhibitors (vemurafenib, dabrafenib), MEK inhibitors (trametinib, cobimetinib), and immune checkpoint inhibitors (ipilimumab). Combined therapy with vemurafenib, cobimetinib, and ipilimumab demonstrated superior overall survival (OS) and progression-free survival (PFS) compared to monotherapy, with a significant odds ratio (OR) of 6.95 (95% CI: 4.25-9.64, p < 0.00001) for OS and 2.49 (95% CI: 1.42-3.56, p < 0.00001) for PFS. Additionally, dabrafenib and trametinib combination therapy showed improved outcomes with favorable tolerability, including a significant reduction in adverse event (AE) risk, with an OR of 2.20 (95% CI: 1.72-2.81). Furthermore, our analysis highlighted vemurafenib-associated dermatological toxicities, emphasizing the need for effective management strategies. The study underscores the evolving treatment landscape in melanoma management, with a potential shift towards immune checkpoint inhibitors in the adjuvant setting, particularly for BRAF-mutated disease. However, limitations in meta-analysis methodologies and the need for long-term investigations into treatment implications on survival and quality of life underscore the importance of continued research., (© 2024.

Background: Advanced phase Philadelphia chromosome-positive myeloid disease-consisting of chronic myeloid leukaemia in the myeloid blast phase and in the accelerated phase, and Philadelphia chromosome-positive acute myeloid leukaemia-is associated with poor outcomes. Although previous studies have suggested the benefit of chemotherapy and BCR::ABL1 tyrosine kinase inhibitor combinations, the optimal regimen is uncertain and prospective studies for this rare group of diseases are scant. Preclinical and retrospective clinical data suggest possible synergy between the BCL-2 inhibitor venetoclax and BCR::ABL1 tyrosine kinase inhibitors. We therefore aimed to design a study to evaluate the safety and activity of a novel combination of decitabine, venetoclax, and the third-generation BCR::ABL1 tyrosine kinase inhibitor ponatinib in advanced phase Philadelphia chromosome-positive myeloid diseases., Methods: For this phase 2 study, patients aged 18 years or older with previously untreated or relapsed or refractory myeloid chronic myeloid leukaemia-blast phase, chronic myeloid leukaemia-accelerated phase, or advanced phase Philadelphia chromosome-positive acute myeloid leukaemia, and an Eastern Cooperative Oncology Group performance status of 0-3 were eligible. Patients were eligible regardless of the number of previous lines of therapy received or previous receipt of ponatinib. Cycle 1 (induction) consisted of a 7-day lead-in of ponatinib 45 mg orally daily (days 1-7), followed by combination therapy with decitabine 20 mg/m 2 intravenously on days 8-12, venetoclax orally daily with ramp-up to a maximum dose of 400 mg on days 8-28, and ponatinib 45 mg orally daily on days 8-28. Cycles 2-24 consisted of decitabine 20 mg/m 2 intravenously on days 1-5, venetoclax orally 400 mg on days 1-21, and ponatinib orally daily on days 1-28. Response-based dosing of ponatinib was implemented in consolidation cycles, with reduction to 30 mg daily in patients who reached complete remission or complete remission with an incomplete haematological recovery and a reduction to 15 mg daily in patients with undetectable BCR::ABL1 transcripts. The primary endpoint was the composite rate of complete remission or complete remission with incomplete haematological recovery in the intention-to-treat population. Safety was assessed in the intention-to-treat population. This trial was registered with ClinicalTrials.gov (NCT04188405) and is still ongoing., Results: Between July 12, 2020, and July 8, 2023, 20 patients were treated (14 with chronic myeloid leukaemia-blast phase, four with chronic myeloid leukaemia-accelerated phase, and two with advanced phase Philadelphia chromosome-positive acute myeloid leukaemia). The median age was 43 years (IQR 32-58); 13 (65%) patients were male and seven (35%) were female; and 12 (60%) were White, three (15%) were Hispanic, four (20%) were Black, and one (5%) was Asian. 12 (60%) patients had received 2 or more previous BCR::ABL1 tyrosine kinase inhibitors, and 14 (70%) patients had at least one high-risk additional chromosomal abnormality or complex karyotype. The median duration of follow-up was 21·2 months (IQR 14·1-24·2). The complete remission or complete remission with an incomplete haematological recovery rate was 50% (10 of 20 patients); complete remission in one [5%] patient and complete remission with incomplete haematological recovery in nine [45%]). An additional six (30%) patients had a morphologic leukaemia-free state. The most common grade 3-4 non-haematological adverse events were febrile neutropenia in eight (40%) patients, infection in six (30%), and alanine or aspartate transaminase elevation in five (25%). Eight (40%) patients had at least one cardiovascular event of any grade. There were three on-study deaths, none of which was considered related to the study treatment and all from infections in the setting of refractory leukaemia., Interpretation: The combination of decitabine, venetoclax, and ponatinib is safe and shows promising activity in patients with advanced phase chronic myeloid leukaemia, including those with multiple previous therapies or high-risk disease features. Further studies evaluating chemotherapy and venetoclax-based combination strategies using newer-generation BCR::ABL1 tyrosine kinase inhibitors are warranted., Funding: Takeda Oncology, the National Institutes of Health, and the National Cancer Institute Cancer Center., Competing Interests: Declaration of interests NJS has received consulting fees from Pfizer, GlaxoSmithKline, NKARTA, Autolus, and Sanofi; research funding from Takeda Oncology, Astellas Pharma, Xencor, Stemline Therapeutics, and NextCure; and honoraria from Adaptive Biotechnologies, Novartis, Amgen, Takeda Oncology, Pfizer, Astellas Pharma, Sanofi, and BeiGene.

Leptomeningeal disease (LMD) is a devastating complication of melanoma with a dismal prognosis. We present the case of a young man with stage IV BRAF V600E mutant melanoma with lung, lymph node, and brain metastases initially treated with ipilimumab and nivolumab, who subsequently developed LMD. Upon change to BRAF/MEK targeted therapy with nivolumab, a durable complete response was achieved and remains ongoing, off treatment, 7 years from diagnosis. Management of symptomatic LMD remains a critical unmet clinical challenge, with limited clinical trial data. This exceptional case is instructive, as the first published case of the use of the triplet, and the first durable response with therapy discontinuation, in melanoma LMD. The triple-drug regimen may be considered a viable option in fit patients. This case highlights the potential for long-term disease control and the critical and urgent need to develop clinical trials inclusive of patients with LMD to define the best treatment strategies., (© 2024 John Wiley & Sons A/S.

Bariatric surgery is increasingly performed to treat severe obesity. As a result of anatomical and physiological changes in the gastrointestinal tract, the pharmacokinetics (PK) of oral drugs can be altered, affecting their efficacy and safety. This includes the class of tyrosine kinase inhibitors (TKIs) which are used to treat chronic myeloid leukemia (CML). This case series describes the clinical course of four CML cases with a history of bariatric surgery. The patients used various TKIs (nilotinib, dasatinib, bosutinib, ponatinib, and imatinib) for which 15 drug levels were measured. The measured TKI concentrations were in part subtherapeutic, and highly variable when compared to mean levels measured in the general population. Multiple drug levels were measured in these patients, as the clinicians were aware of the possible impact of bariatric surgery. The drug levels were used as additional input for clinical decision-making. All four patients required TKI switches and/or dose modifications to achieve an effective and tolerable treatment. Eventually, adequate clinical and molecular remissions were achieved in all cases. In summary, TKI concentrations of patients undergoing bariatric surgery may be subtherapeutic. Moreover, there is substantial interindividual and intraindividual variation, which may be explained by the complex interference of bariatric surgery and associated weight loss. For clinical practice, therapeutic drug monitoring is advised in patients with a history of bariatric surgery in case of suboptimal response or loss of response., (© 2024. The Author(s).)

Twenty adults with newly diagnosed (ND) or relapsed/refractory (RR) Ph-positive acute lymphoblastic leukemia (ALL), or chronic myeloid leukemia in lymphoid blast phase (CML-LBP), were treated with mini-hyperCVD, ponatinib, and blinatumomab. Complete molecular response was achieved in 78% of ND patients, while CR/CRi was achieved in 100% of RR and CML-LBP. The 3-year overall survival rate was 76% (95% CI, 47%-90%)., (© 2024 Wiley Periodicals LLC.)

The global aging population is leading to an increasing incidence of cancer, exacerbating the global burden of cancer. By 2040, the total number of cancer patients worldwide is projected to reach 28 million. With advancements in tumor molecular biology research and the widespread application of next-generation sequencing technology, precision treatment for cancer has made significant progress in clinical settings. Selective targeting of the Braf gene has emerged as one of the early successful cases of precision medicine for tumors. Braf gene mutations can result in unrestricted activation of downstream kinases in the mitogen-activated protein kinase (MAPK) cell signaling pathway, promoting rapid proliferation of tumor cells. BRAF inhibitors, either as monotherapy or in combination with MEK inhibitor, have been approved for various cancers, including melanoma, non-small cell lung cancer, thyroid cancer, colorectal cancer and glioma, among others. Clinical studies related to BRAF inhibitors are continuously exploring new applications. However, there is currently no consensus on the use of BRAF inhibitors in the diagnosis and treatment of multiple solid cancers in China. This article integrates clinical evidence of Braf mutations in multiple solid cancers to establish an expert consensus on the diagnosis and treatment of malignant solid cancers with Braf gene mutations. The goal is to promote and guide the standardized application of BRAF inhibitors.

Background: The recommended first-line treatment for advanced epidermal growth factor receptor (EGFR)-mutant non-small-cell lung cancer (NSCLC) patients is EGFR-tyrosine kinase inhibitors (EGFR-TKIs). BRAF alterations have been identified as resistance mechanisms. We aimed to identify features of and subsequent treatment strategies for such patients., Patients and Methods: We conducted a systematic literature review of NSCLC patients harboring acquired BRAF alterations. Additionally, BRAF-altered NSCLC patients who progressed from EGFR-TKIs at West China Hospital of Sichuan University were screened. Patient characteristics, treatment options, and outcomes were analyzed., Results: A total of 104 patients were included, 2 of whom came from our center. Seventy-five patients (72.1%) harbored BRAF mutations (57 class I mutations, 7 class II mutations, 9 class III mutations, and 2 non-class I-III mutations), and 29 (27.9%) harbored BRAF fusions. Eighteen patients received triple-targeted therapy, including prior EGFR-TKIs plus dabrafenib and trametinib, and 23 patients received other treatments. The median progression-free survival was significantly longer in patients receiving triple-targeted therapy than in those receiving other treatments (8.0 versus 2.5 months, P < 0.001). Similar findings were observed in patients with BRAF mutations (9.0 versus 2.8 months, P = 0.004), particularly in those with BRAF class I mutations (9.0 versus 2.5 months, P < 0.001). A potential benefit was also observed among patients with BRAF fusions (5.0 versus 2.0 months, P = 0.230). Twenty patients (48.8%) experienced adverse events. Dose reduction of RAF or MEK inhibitor was required in five patients (12.2%). Five patients (12.2%) permanently discontinued treatment (three on triple-targeted therapy; one on prior EGFR-TKI plus vemurafenib; one on prior EGFR-TKI plus trametinib)., Conclusions: BRAF alterations, specifically BRAF mutations and BRAF fusions, facilitate resistance to EGFR-TKIs. Triple-targeted therapy is effective and safe for patients with EGFR-mutant NSCLC with acquired BRAF alterations, mainly among patients with BRAF class I mutations and potentially in patients with BRAF fusions., (Copyright © 2024 The Author(s).

Purpose: Patients with BRAF V600 / NRAS Q61 wild-type melanoma who progress after immune checkpoint inhibitors (ICIs) have a poor prognosis. MEK inhibition has shown activity in this patient population but is associated with treatment-limiting skin toxicity. Combining a BRAF inhibitor with a MEK inhibitor is associated with less skin toxicity., Methods: This phase II trial investigated trametinib (2 mg once daily) in patients with advanced BRAF V600 / NRAS Q61 wild-type, ICI-refractory melanoma. In case of treatment-limiting skin toxicity, low-dose dabrafenib (50 mg twice daily) was added to trametinib. After a trial amendment, both drugs were combined up-front. The confirmed objective response rate (cORR) served as the primary end point., Results: Twenty-four patients were included (50% male; median age 57 years; 92% Eastern Cooperative Oncology Group Performance Status 0-2; 75% stage IV-M1c/stage IV-M1d; median number of prior therapies: two [range, 1-5]). Three patients were enrolled before and 21 patients after the amendment, respectively. Seven confirmed and one unconfirmed partial responses (PRs) were observed (cORR, 29.2%). The median duration of response was 16.6 weeks (95% CI, 5.5 to 27.7). Stable disease (SD) was the best response in an additional five patients. Among the responding patients, genetic alterations causing mitogen-activated protein kinase (MAPK) pathway activation were documented in six patients. The disease control rate in patients with MAPK pathway-activating alterations was 64.3% (five confirmed PR, one unconfirmed PR, and three SD). The median progression-free survival was 13.3 weeks (95% CI, 3.5 to 23.1), and the median overall survival was 54.3 weeks (95% CI, 37.9 to 70.6). Adding low-dose dabrafenib to trametinib effectively mitigated or prevented treatment-limiting trametinib-related skin toxicity., Conclusion: The combination of trametinib plus low-dose dabrafenib demonstrated encouraging efficacy and effective mitigation of skin toxicity in patients with advanced, ICI-pretreated BRAF V600 / NRAS Q61 wild-type melanoma patients. MAPK pathway-activating alterations hold promise as a predictive biomarker.

Objective/background: The short-term efficacy and safety of daridorexant, a dual orexin receptor antagonist, has been demonstrated in Japanese patients with insomnia disorder. The objective of this study was to evaluate, in a non-overlapping patient population to the short-term study, the long-term safety and efficacy of daridorexant in Japanese patients with insomnia disorder., Patients/methods: In this Phase 3 open-label study conducted in Japan, 154 patients with insomnia disorder were randomized to daridorexant 50 mg (n = 102) or 25 mg (n = 52) for 52 weeks. The primary objective was to assess the safety and tolerability of daridorexant for up to 1 year. Secondary exploratory objectives were to evaluate the long-term efficacy of daridorexant on subjective sleep parameters (total sleep time, latency to sleep onset and wake after sleep onset) and daytime functioning (Insomnia Daytime Symptoms and Impacts Questionnaire)., Results: The incidence of treatment-emergent adverse events (TEAEs) was 74 % and 58 % in the 50 mg and 25 mg groups respectively. No serious drug-related TEAEs were reported. Both doses improved next-morning sleepiness (Visual Analog Scale) throughout the study. Five adjudicated adverse events of special interest were reported; excessive daytime sleepiness (n = 1, 25 mg; n = 2, 50 mg), sleep paralysis (n = 1, 50 mg) and nightmare (n = 1, 25 mg). Improvements in sleep and daytime functioning were maintained from Week 2 (first assessment) through to Week 52 in both dose groups., Conclusions: Up to 52-weeks, daridorexant was well tolerated with sustained improvement in sleep onset, sleep maintenance and daytime functioning, supporting its long-term use in Japanese patients with insomnia disorder., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: All authors report financial support, administrative support, and writing assistance were provided by Nxera Pharma Japan Co., Ltd.

Background: Ponatinib is a third-generation BCR::ABL1 tyrosine kinase inhibitor (TKI) with robust activity in Philadelphia chromosome-positive leukemias. Herein, we report the long-term follow-up of the phase 2 trial of ponatinib in chronic myeloid leukemia in chronic phase., Methods: Patients received ponatinib 30 to 45 mg/day. The primary end point was the rate of 6-month complete cytogenetic response (CCyR). The study was held in June 2014 because of the risk of cardiovascular toxicity, requiring patients to change TKI., Results: Fifty-one patients were treated with ponatinib (median dose, 45 mg/day). Median age was 48 years (range, 21-75); 30 (59%) had baseline cardiovascular comorbidities. Median treatment duration was 13 months (range, 2-25). Fourteen patients (28%) discontinued ponatinib because of toxicities, 36 (71%) after the Food and Drug Administration warning/study closure, and one for noncompliance. Dasatinib was the most frequently chosen second-line TKI (n = 34; 66%). Among 46 patients evaluable at 6 months, 44 (96%) achieved CCyR, 37 (80%) major molecular response, 28 (61%) MR4, and 21 (46%) MR4.5. The cumulative 6-month rates of CCyR, major molecular response, MR4, and MR4.5 were 96%, 78%, 50%, and 36%, respectively. Durable MR4 ≥24 or ≥60 months was observed in 67% and 51% of patients, respectively. The 24-month event-free survival rate was 97%. After a median follow-up of 128 months, the 10-year overall survival rate was 90%. Eight patients (16%) had serious grade 2 to 3 cardiovascular adverse events, leading to permanent discontinuation in five (10%)., Conclusion: Ponatinib yielded high cytogenetic and molecular responses in newly diagnosed chronic myeloid leukemia in chronic phase. Its use in the frontline setting is hindered by arterio-/vaso-occlusive and other severe toxicities., (© 2024 American Cancer Society.)

Objective: This Phase 3 double-blind, placebo-controlled study evaluated the efficacy and safety of daridorexant in Japanese patients with insomnia disorder., Patients/methods: 490 patients with insomnia disorder from 95 sites in Japan were randomized to daridorexant 50 mg (n = 163), 25 mg (n = 163) or placebo (n = 164) for 4 weeks, followed by a 7-day placebo run-out and a 30-day safety follow-up. The primary efficacy endpoints, in hierarchical order, were change from baseline at Week 4 in subjective total sleep time (sTST) and subjective latency to sleep onset (sLSO), for daridorexant 50 mg vs placebo. sTST and sLSO were also evaluated (secondary endpoints) for daridorexant 25 mg vs placebo. Safety endpoints included adverse events and next-morning sleepiness (Visual Analog Scale, VAS)., Results: Daridorexant 50 mg significantly increased sTST and decreased sLSO versus placebo at Week 4 (least-squares mean difference [LSMD]: sTST 20.3 min [95 % CI 11.4, 29.2] p < 0.001; sLSO -10.7 min [-15.8, -5.5] p < 0.001). Daridorexant 25 mg also significantly improved both endpoints versus placebo (LSMD: sTST 9.2 min [0.3, 18.1] p = 0.042; sLSO -7.2 min [-12.3, -2.0] p = 0.006). Overall incidence of adverse events was similar across groups (50 mg: 22 %; 25 mg: 18 %; placebo 23 %); somnolence, the most common event, increased with increasing dose (50 mg: 6.8 %; 25 mg: 3.7 %; placebo 1.8 %). However, daridorexant did not increase VAS next-morning sleepiness. No rebound or withdrawal-related symptoms were observed after treatment discontinuation., Conclusions: In Japanese patients with insomnia disorder, daridorexant (25 and 50 mg) was well tolerated and significantly improved subjective sleep outcomes, with no evidence of residual effects., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: All authors report financial support, administrative support, and writing assistance were provided by Nxera Pharma Japan Co., Ltd.

Background: Nasotracheal intubation is associated with a risk of epistaxis. Several drugs, including cocaine and xylometazoline may be used as decongestants prior to nasotracheal intubation to prevent this. We hypothesized that xylometazoline would prevent epistaxis more effectively than cocaine, demonstrated by a lower proportion of patients with bleeding after nasotracheal intubation., Methods: We conducted a single-center, outcome assessor and analyst-blinded, clinical randomized controlled trial following approval from the local research ethics committee and the national medicine agency. Written informed consent was obtained from all patients. Patients scheduled for surgery under general anesthesia with nasotracheal intubation were randomized to receive either 2 mL 4% cocaine or 2 mL 0.05% xylometazoline prior to nasotracheal intubation. Immediately following intubation, epistaxis was evaluated by the blinded intubating anesthetist on a four-point scale. We measured heart rate and blood pressure the first 5 min after drug administration. Adverse events were followed up after 24 h., Results: A total of 53 patients received cocaine and 49 patients received xylometazoline. Bleeding occurred in 32 patients receiving cocaine (60.4%) and in 34 patients receiving xylometazoline (69.4%) (p = .41, Fisher's exact test) with a difference of 9.0% (95% CI: -9.4% to 27%). There was no statistically significant difference between groups regarding the heart rate or blood pressure. No adverse cardiac events were recorded in either group., Conclusion: We found no statistically significant difference between cocaine and xylometazoline in preventing epistaxis after nasotracheal intubation, and the choice of vasoconstrictor should be based on other considerations, such as pricing, availability and medicolegal issues., (© 2024 The Author(s).

The study aimed to investigate the changes in the levels of serum bone turnover markers (BTMs) and bone mineral density (BMD) Z-score in pediatric patients with osteogenesis imperfecta (OI) after intravenous bisphosphonate therapy and their association with age and estimated glomerular filtration rate (eGFR). This retrospective study analyzed data from 10 pediatric OI patients treated with intravenous zoledronic acid for over 1 year. Patients' clinical data were collected. The levels of BTMs and BMD Z-score before and after zoledronic acid treatment were analyzed. Significant improvement in BMD Z-score was observed after 6 and 12 months of treatment compared to baseline (all p < 0.05). The N-terminal propeptide of type I procollagen (PINP) levels decreased over time (all p < 0.05), indicating that zoledronic acid treatment decreased bone turnover. The levels of beta-C-terminal telopeptide of type I collagen remained stable after treatment. No correlation was found between PINP level and age, eGFR, or BMD (all p > 0.05). Bisphosphonate treatment can improve BMD and decrease bone turnover (indicated by decreased levels of PINP) in pediatric OI patients. PINP may serve as an independent indicator for monitoring the efficacy of bisphosphonate treatment in pediatric OI patients, particularly in those under the age of 6, where standardized BMD Z-score criteria are lacking., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: BRAF mutations are detected in 30%-80% of papillary thyroid cancer (PTC) cases. DaBRAFenib and trametinib showed promising antitumor activity in patients with BRAFV600E-mutated metastatic melanoma and non-small cell lung cancer. This study aimed to evaluate the efficacy and safety of daBRAFenib and trametinib in patients with metastatic BRAFV600E-mutated thyroid cancer., Materials and Methods: This was a retrospective study to evaluate the efficacy of daBRAFenib and trametinib in patients with metastatic BRAFV600E-mutated PTC. The patients received daBRAFenib 150 mg twice daily and trametinib 2 mg once daily at the Samsung Medical Center. This study evaluated the progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR) overall survival (OS), and safety of daBRAFenib and trametinib., Results: Between December 2019 and January 2022, 27 PTC patients including eight patients with poorly differentiated or anaplastic transformation, received daBRAFenib and trametinib. The median age was 73.0 years, and the median follow-up period was 19.8 months. The majority (81.5%) had undergone thyroidectomy, while 8 patients had received prior systemic treatments. ORR was 73.1%, with 19 partial responses, and DCR was 92.3%. Median PFS was 21.7 months, and median OS was 21.7 months. Treatment-related adverse events included generalized weakness (29.6%), fever (25.9%), and gastrointestinal problems (22.2%). Dose reduction due to adverse events was required in 81.5% of the patients., Conclusion: DaBRAFenib and trametinib demonstrated a high ORR with promising PFS; however, most patients with BRAFV600E-mutated metastatic PTC required a dose reduction.

BCR-ABL1 compound mutations can lead to resistance to ABL1 inhibitors in chronic myeloid leukemia (CML), which could be targeted by combining the ATP-site inhibitor ponatinib and the allosteric inhibitor asciminib. Here, we report the clinical validation of this approach in a CML patient, providing a basis for combination therapy to overcome such resistance., Competing Interests: Declaration of interests B.J.D. serves on scientific advisory boards for Aileron Therapeutics, Therapy Architects (ALLCRON), Cepheid, Vivid Biosciences, Celgene, RUNX1 Research Program, Novartis, Gilead Sciences (inactive), and Monojul (inactive); serves on scientific advisory boards and receives stock from Aptose Biosciences, Blueprint Medicines, EnLiven Therapeutics, Iterion Therapeutics, Third Coast Therapeutics, and GRAIL (inactive on scientific advisory board); is scientific founder of MolecularMD (inactive, acquired by ICON); serves on the board of directors and receives stock from Amgen and Vincera Pharma; serves on the board of directors for Burroughs Wellcome Fund and CureOne; serves on the joint steering committee for Beat AML LLS; is founder of VB Therapeutics; has a sponsored research agreement with EnLiven Therapeutics; receives clinical trial funding from Novartis, Bristol-Myers Squibb, and Pfizer., (Copyright © 2024 Elsevier Inc.

Background: Depression is often linked to inflammation in the brain. Researchers have been exploring ways to reduce this inflammation to improve depression symptoms. One potential target is a protein called RIPK1, which is known to contribute to brain inflammation. However, it's unclear how RIPK1 influences depression. Our study aims to determine whether RIPK1 inhibition could alleviate neuroinflammation-associated depression and elucidate its underlying mechanisms., Methods: To investigate our research objectives, we established a neuroinflammation mouse model by administering LPS. Behavioral and biochemical assessments were conducted on these mice. The findings were subsequently validated through in vitro experiments., Results: Using LPS-induced depression models, we investigated RIPK1's role, observing depressive-like behaviors accompanied by elevated cytokines, IBA-1, GFAP levels, and increased inflammatory signaling molecules and NO/H 2 O 2 . Remarkably, Necrostatin (Nec-1 S), a RIPK1 inhibitor, mitigated these changes. We further found altered expression and phosphorylation of eIF4E, PI3K/AKT/mTOR, and synaptic proteins in hippocampal tissues, BV2, and N2a cells post-LPS treatment, which Nec-1 S also ameliorated. Importantly, eIF4E inhibition reversed some of the beneficial effects of Nec-1 S, suggesting a complex interaction between RIPK1 and eIF4E in LPS-induced neuroinflammation. Moreover, citronellol, a RIPK1 agonist, significantly altered eIF4E phosphorylation, indicating RIPK1's potential upstream regulatory role in eIF4E and its contribution to neuroinflammation-associated depression., Conclusion: These findings propose RIPK1 as a pivotal mediator in regulating neuroinflammation and neural plasticity, highlighting its significance as a potential therapeutic target for depression., (© 2024.

Background: Acute-phase reactions (APRs) are common among people treated for the first time with zoledronate (ZOL). The current view is that both the APRs caused by ZOL and its efficacy are related to the mevalonic acid pathway. However, the relationship between APRs and ZOL efficacy remains unclear., Methods: This was a prospective observational cohort study involving postmenopausal women with osteoporosis in Shanghai, China, for 1 year. A total of 108 patients with an average age of 67.4 ± 5.8 years were treated with 5 mg intravenous ZOL for the first time. Data on demographic characteristics, APRs, blood counts, bone turnover markers, including C-telopeptide collagen crosslinks (CTX) and N-terminal propeptide of type 1 collagen (PINP), and bone mineral density (BMD) were collected., Results: (1) The results did not reveal a relationship between APRs and changes in bone turnover markers and BMD but showed that changes in body temperature (T) within 3 days after administration were positively correlated with changes in the BMD of the LS at Month 12 (β = 0.279 P = 0.034). (2) This effect was mediated mainly by changes in serum CTX (b = 0.046, 95% CI [0.0010-0.0091]). (3) The ROC curve revealed that when T increased by 1.95 °C, the sensitivity and specificity of identifying clinically important changes in LS BMD after 1 year were optimized., Conclusions: In this study, we tested the hypothesis that people with elevated body T after initial ZOL treatment had greater improvements in BMD and better outcomes., Trial Registration: NCT, NCT03158246.

Purpose: This study aims to prospectively analyze the effects of anticholinergic therapy using imidafenacin on detrusor overactivity occurring after robot-assisted radical prostatectomy (RARP)., Materials and Methods: Patients were followed-up at outpatient visits 2-4 weeks post-surgery (visit 2) to confirm the presence of urinary incontinence. Those confirmed with urinary incontinence were randomly assigned in a 1:1 ratio to the anticholinergic medication group (imidafenacin 0.1 mg twice daily) or the control group. Patients were followed-up at 1, 3, and 6 months post-surgery for observational assessments, including the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS)., Results: A total of 49 patients (25 in the treatment group and 24 in the control group) were randomized for the study. There were no differences observed between the groups in terms of age, comorbidities, prostate size, or pathological staging. According to the IPSS questionnaire results, there was no statistically significant difference between the medication and control groups (p=0.161). However, when comparing storage and voiding symptoms separately, there was a statistically significant improvement in storage symptom scores (p=0.012). OABSS also revealed statistically significant improvement in symptoms from 3 months post-surgery (p=0.005), which persisted until 6 months post-surgery (IPSS storage: p=0.023, OABSS: p=0.013)., Conclusions: In the case of urinary incontinence that occurs after RARP, even if the function of the intrinsic sphincter is sufficiently preserved, if urinary incontinence persists due to changes in the bladder, pharmacological therapy using imidafenacin can be beneficial in managing urinary incontinence., Competing Interests: The authors have nothing to disclose., (© The Korean Urological Association.)

Targeted therapy has the potential to be used in the neoadjuvant setting for odontogenic tumors, reducing the morbidities associated with major surgery. In this regard, the aim of this study was to summarize the current evidence on the different forms of targeted therapy, effectiveness, and drawbacks of this course of treatment. Four databases were searched electronically without regard to publication date or language. Grey literature searches and manual searches were also undertaken. Publications with sufficient clinical data on targeted therapy for odontogenic tumors were required to meet the criteria for eligibility. The analysis of the data was descriptive. A total of 15 papers comprising 17 cases (15 ameloblastomas and 2 ameloblastic carcinomas) were included. Numerous mutations were found, with BRAF V600E being most common. Dabrafenib was the most utilized drug in targeted therapy. Except for one case, the treatment reduced the size of the lesion (16/17 cases), showing promise. Most of the adverse events recorded were mild, such as skin issues, voice changes, abnormal hair texture, dry eyes, and systemic symptoms (e.g., fatigue, joint pain, and nausea). It is possible to reach the conclusion that targeted therapy for ameloblastoma and ameloblastic carcinoma may be a useful treatment strategy, based on the findings of the included studies., (© 2024 Wiley Periodicals LLC.)

Introduction: The first targeted therapy in oncology, imatinib, revolutionized chronic myeloid leukemia (CML) treatment and spurred research in targeted therapies for various cancers. CML results from a chromosomal translocation, forming the BCR-ABL1 fusion gene. Asciminib has been recently approved for third-line refractory or intolerant patients. Treatment-free remission (TFR) is attainable with sustained deep molecular response (DMR) and this approach could be incorporated into pharmacoeconomic models., Aims: To establish a cost-effectiveness model comparing asciminib to approved third-generation tyrosine kinase inhibitors (TKIs) (bosutinib and ponatinib) with a focus on achieving TFR. Additionally, the budgetary impact of incorporating asciminib as a therapeutic alternative is assessed., Methods: This model is based on a Markov chain with 7 states. The condition for achieving TFR is to remain for 5 years in DMR state. Efficacy of the model was measured in QALYs, and the costs included in the base case analysis are based in Spain. A probabilistic (PSA) and deterministic analysis (DSA) were carried out to assess the variability of the model. There were achieved 2 independent models comparing asciminib vs bosutinib and asciminib vs ponatinib., Results: Asciminib, when compared with ponatinib, is a cost-saving alternative, as efficacy is similar between alternatives, and asciminib have a lower cost of 30,275€. Asciminib showed 4.33 more QALYs and a higher cost (203,591€) than bosutinib, resulting in an ICER of €47,010.49 per QALY. PSA shows that the parameters with higher influence in the variability of the model were the probability of transitioning to BP and probabilities of achieving MMR and DMR. A one-way analysis reports that the drug cost has a higher influence on both models, and the discount rate significantly affects the asciminib vs bosutinib model., Conclusion: Asciminib broadens therapeutic choices for patient's refractory or intolerant to 2 prior lines of treatment in a cost-effectiveness manner. The costs of drugs significantly impact the overall cost of the disease, emphasizing the importance of the selected discount rates for each drug. Given the relatively low incidence of CML, the introduction of asciminib has a limited budgetary impact, warranting individualized decisions based on patient`s clinical characteristics., Competing Interests: Declaration of competing interest Author declares no conflict of interest., (Copyright © 2024 Sociedad Española de Farmacia Hospitalaria (S.E.F.H).

Purpose: Treatment of metastatic pancreatic neuroendocrine tumors (pancNETs), particularly grade 2 (G2) and grade 3 (G3), often presents a dilemma in choosing from multiple similarly efficacious therapies. Data on targeted therapies for these tumor types is limited, and this report presents BRAF-targeted therapy as a therapeutic option for metastatic pancNET G3., Methods: This is a case report of a patient with G3 pancNET metastatic to the liver, lung, lymph node, and scalp (soft tissue) treated with dabrafenib/trametinib (D/T) in the presence of a BRAF V600E mutation detected in tumor tissue., Results: This patient has demonstrated an ongoing partial response to therapy at all involved sites for nearly 15 months with minimal side effects attributable to D/T., Conclusion: Dabrafenib/trametinib therapy for BRAF-mutated metastatic pancNETs provides a novel treatment option and, especially in the G3 setting, should be considered a first-line option. Tumor testing for actionable mutations should be undertaken at the time of diagnosis and/or progression to identify novel therapeutic avenues in these rare tumors., (© 2024. The Author(s).)

Immune checkpoint inhibitors and BRAF-targeted therapy each improve survival in melanoma. Immune changes early during targeted therapy suggest the mechanisms of each drug class could work synergistically. In the non-comparative, randomized, phase 2 NeoTrio trial, we investigated whether targeted therapy could boost the proportion of patients achieving long-term recurrence-free survival with neoadjuvant immunotherapy in resectable stage III BRAF V600 -mutant melanoma. Sixty patients (42% females) were randomized to pembrolizumab alone (n = 20), sequential therapy (dabrafenib plus trametinib followed by pembrolizumab; n = 20) or concurrent (triple) therapy (n = 20), followed by surgery and adjuvant therapy. The primary outcome was pathological response; secondary outcomes included radiographic response, recurrence-free survival, overall survival, surgical outcomes, peripheral blood and tumor analyses and safety. The pathological response rate was 55% (11/20; including six pathological complete responses (pCRs)) with pembrolizumab, 50% (10/20; three pCRs) with sequential therapy and 80% (16/20; ten pCRs) with concurrent therapy, which met the primary outcome in each arm. Treatment-related adverse events affected 75-100% of patients during neoadjuvant treatment, with seven early discontinuations (all in the concurrent arm). At 2 years, event-free survival was 60% with pembrolizumab, 80% with sequential therapy and 71% with concurrent therapy. Recurrences after major pathological response were more common in the targeted therapy arms, suggesting a reduction in response 'quality' when targeted therapy is added to neoadjuvant immunotherapy. Risking the curative potential of immunotherapy in melanoma cannot be justified. Pending longer follow-up, we suggest that immunotherapy and targeted therapy should not be combined in the neoadjuvant setting for melanoma. ClinicalTrials.gov registration: NCT02858921 ., (© 2024.

Allogeneic hematopoietic cell transplantation (HCT) offers a potential cure in Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL); nonetheless, relapses are common and the major cause of mortality. One strategy to prevent relapse is tyrosine kinase inhibitor (TKI) maintenance post-HCT, but published clinical experience is primarily with the first-generation TKI imatinib while data with newer generation TKIs are limited. We conducted a retrospective analysis of 185 Ph+ ALL patients who underwent HCT followed by TKI maintenance from 2003 to 2021 at City of Hope. Initially, 50 (27.0%) received imatinib, 118 (63.8%) received a second-generation TKI (2G-TKI), and 17 (9.2%) received ponatinib. A total of 77 patients (41.6%) required a dose reduction of their initial TKI due to toxicity. Sixty-six patients (35.7%) did not complete maintenance due to toxicity; 69 patients (37.3%) discontinued 1 TKI, and 11 (5.9%) discontinued 2 TKIs due to toxicity. Initial imatinib versus 2G-TKI versus ponatinib maintenance was discontinued in 19 (38.0%) versus 68 (57.6%) versus 3 (17.6%) patients due to toxicity (p = .003), respectively. Patients on ponatinib as their initial TKI had a longer duration of TKI maintenance versus 2G-TKI: 576.0 days (range, 72-921) versus 254.5 days (range, 3-2740; p = .02). The most common reasons for initial TKI discontinuation include gastrointestinal (GI) intolerance (15.1%), cytopenia (8.6%), and fluid retention (3.8%). The 5-year overall survival and progression-free survival for the total population were 78% and 71%, respectively. Our findings demonstrate the challenges of delivering post-HCT TKI maintenance in a large real-world cohort as toxicities leading to TKI interruptions, discontinuation, and dose reduction were common., (© 2024 Wiley Periodicals LLC.)

Purpose: Among cases of breast cancer, estrogen receptor-positive (ER +), PIK3CA-mutant, HER2- advanced breast cancer stands as a particularly complex clinical indication where approximately 40% of ER + /HER2- breast carcinomas present mutations in the PIK3CA gene. A significant hurdle in treating ER + breast cancer lies in surmounting the challenges of endocrine resistance. In the clinical setting, a multifaceted approach is essential for this indication, one that not only explores the effectiveness of individual treatments but also delves into the potential gains in therapeutic outcome from combination therapies., Methods: In the current study, longitudinal tumor growth inhibition (TGI) models were developed to characterize tumor response over time in postmenopausal women with ER + /HER2- advanced or metastatic breast cancer undergoing treatment with fulvestrant alone or in combination with the PI3K inhibitor, taselisib. Impact of clinically relevant covariates on TGI metrics was assessed to identify patient subsets most likely to benefit from treatment with fulvestrant monotherapy or combination with taselisib., Results: Tumor growth rate constant (K g ) was found to increase with increasing baseline tumor size and in the absence of baseline endocrine sensitivity. Further, K g decreased in the absence of baseline liver metastases both in fulvestrant monotherapy and combination therapy with taselisib. Overall, additive/potentially synergistic anti-tumor effects were observed in patients treated with the taselisib-fulvestrant combination., Conclusion: These results have important implications for understanding the therapeutic impact of combination treatment approaches and individualized responses to these treatments. Finally, this work, emphasizes the importance of model informed drug development for targeted cancer therapy., Clinical Trial Registration: NCT02340221 Registered January 16, 2015, NCT01296555 Registered February 14, 2011., (© 2024.

Acquired drug resistance is the major cause for disease recurrence in cancer patients, and this is particularly true for patients with metastatic melanoma that carry a BRAF V600E mutation. To address this problem, we investigated cyclic membrane-active peptides as an alternative therapeutic modality to kill drug-tolerant and resistant melanoma cells to avoid acquired drug resistance. We selected two stable cyclic peptides (cTI and cGm), previously shown to have anti-melanoma properties, and compared them with dabrafenib, a drug used to treat cancer patients with the BRAF V600E mutation. The peptides act via a fast membrane-permeabilizing mechanism and kill metastatic melanoma cells that are sensitive, tolerant, or resistant to dabrafenib. Melanoma cells do not become resistant to long-term treatment with cTI, nor do they evolve their lipid membrane composition, as measured by lipidomic and proteomic studies. In vivo studies in mice demonstrated that the combination treatment of cTI and dabrafenib resulted in fewer metastases and improved overall survival. Such cyclic membrane-active peptides are thus well suited as templates to design new anticancer therapeutic strategies., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: One of the prominent causes of chronic liver disease worldwide is the hepatitis C virus (HCV). HCV believed that innate immunity contributes to a sustained virological response (SVR) to the treatment of Sofosbuvir (SOF) (+) Daclatasvir (DCV) (+) Ribavirin (RBV). This study aimed to evaluate the impact of SOF (+) DCV (+) RBV therapy and persistent HCV infection on the subset of natural killer cells (NK) in HCV genotype four patients from Egypt., Materials and Methods: One hundred and ten patients with persistent HCV infections requiring SOF (+) DCV (+) RBV therapy were grouped, and a flow cytometry (FCM) study of the NK cell subset in peripheral blood was performed. The assessment was performed before and after three and/or six months of the cessation of viral suppression therapy when a patient had a long-term viral response (SVR). One hundred and ten volunteers from the National Liver Institute ' s (NLI) blood bank were selected as controls., Results: Patients with chronic HCV infection before therapy had considerably lower CD16 + and CD3 - CD56 + cells than controls. Their levels increase during SOF (+) DCV (+) RBV therapy. In patients with SVR during treatment, CD16 + and CD3 - CD56 + cells increased significantly compared to those who did not get SVR. Furthermore, CD56 + cells were significantly higher in patients with persistent infection before treatment than controls but diminished with the response to treatment., Conclusion: NK cell activation following SOF (+) DCV (+) RBV therapy and polarization to cytotoxicity occurred early in HCV antiviral therapy and was elevated in the respondents. Our data illustrated that establishing an inhibitory cytotoxic NK profile is related to therapeutic outcomes., (Copyright © 2024. Published by Elsevier Masson SAS.)

Background: This 6-month randomized split-mouth and placebo-controlled clinical trial aimed to evaluate the clinical and radiographic efficacy of adjunctive use of 0.05% zoledronate (ZLN) gel as local drug delivery to scaling and root planing (SRP) in stage III, grade B periodontitis patients with and without controlled type-2 diabetes mellitus (DM)., Methods: A total of 120 infrabony sites were divided into two groups: Group-1 (non-diabetic periodontitis) and Group-2 (periodontitis + DM). A total of 60 sites in each group were randomized to receive treatment with SRP + placebo gel (control) or SRP + 0.05% ZLN gel (test). Plaque index (PI), modified sulcus bleeding index (mSBI), pocket probing depth (PPD), and relative attachment levels (RAL) were assessed at baseline, 3 and 6 months, and digital intraoral periapical and cone-beam computed tomography imaging were used to measure the linear and percentage reduction of intrabony defect depth (DD, DDR%) after 6 months., Results: Group-1 showed significant reduction in PI (0.56 ± 0.15 and 0.52 ± 0.19 from 0.67 ± 0.17), mSBI (0.7 ± 0.60 and 0.47 ± 0.57 from 0.9 ± 0.48), PPD (4.6 ± 0.85 and 3.43 ± 0.63 from 6.5 ± 1.04) and gain in RAL (7.03 ± 0.85 and 5.93 ± 0.69 from 8.9 ± 1.09) in the ZLN-treated sites than the placebo sites and also from Group-2 sites after 3 and 6 months, respectively. A significant reduction in DD of 28.79% in Group-1 and 22.20% in Group-2 at ZLN sites was seen compared to placebo sites of both groups., Conclusion: ZLN gel applied subgingivally in infrabony pockets resulted in significant clinical improvements evident by probing depth reduction and gain in attachment levels along with radiographic evidence of more bone fill seen in non-diabetic patients compared to diabetic periodontitis patients., (© 2023 American Academy of Periodontology.)

Drug resistance is a significant challenge in cancer chemotherapy and is a primary factor contributing to poor recovery for cancer patients. Although drug-loaded nanoparticles have shown promise in overcoming chemotherapy resistance, they often carry a combination of drugs and require advanced design and manufacturing processes. Furthermore, they seldom approach chemotherapy-resistant tumors from an immunotherapy perspective. In this study, we developed a therapeutic nanovaccine composed solely of chemotherapy-induced resistant tumor antigens (CIRTAs) and the immune adjuvant Toll-like receptor (TLR) 7/8 agonist R848 (CIRTAs@R848). This nanovaccine does not require additional carriers and has a simple production process. It efficiently delivers antigens and immune stimulants to dendritic cells (DCs) simultaneously, promoting DCs maturation. CIRTAs@R848 demonstrated significant tumor suppression, particularly when used in combination with the immune checkpoint blockade (ICB) anti-PD-1 (αPD-1). The combined therapy increased the infiltration of T cells into the tumor while decreasing the proportion of regulatory T cells (Tregs) and modulating the tumor microenvironment, resulting in long-term immune memory. Overall, this study introduces an innovative strategy for treating chemotherapy-resistant tumors from a novel perspective, with potential applications in personalized immunotherapy and precision medicine., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

We present a mathematical model of the evolutionary dynamics of a metastatic tumour under chemotherapy, comprising non-local partial differential equations for the phenotype-structured cell populations in the primary tumour and its metastasis. These equations are coupled with a physiologically-based pharmacokinetic model of drug administration and distribution, implementing a realistic delivery schedule. The model is carefully calibrated from the literature, focusing on BRAF-mutated melanoma treated with Dabrafenib as a case study. By means of long-time asymptotic and global sensitivity analyses, as well as numerical simulations, we explore the impact of cell migration from the primary to the metastatic site, physiological aspects of the tumour tissues and drug dose on the development of chemoresistance and treatment efficacy. Our findings provide a possible explanation for empirical evidence indicating that chemotherapy may foster metastatic spread and that metastases may be less impacted by the chemotherapeutic agent., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background: Giant cell reparative granulomas are nonneoplastic, benign lesions that can expand and dissolve bone. Fibrous dysplasia is a benign condition in which normal bone tissue is replaced by abnormally proliferating immature reticular bone and fibrous tissue. The combination of giant cell reparative granuloma and fibrous dysplasia is extremely rare and can pose diagnostic and therapeutic challenges because of the complexity of clinical presentation., Case Presentation: We here present a patient who had a combination of fibrous dysplasia of bone and a giant cell reparative granuloma. An elderly male was admitted to the hospital with a blood-streaked nasal discharge, blurry vision in his right eye, and an enlarged mass under the chin. A CT scan revealed that the lesion had infiltrated the head and face extensively, including the right maxillary sinus, sieve sinus, and the right nasal cavity, contraindicating surgery. The patient received a total dose of 30 Gy of 6 MV x-ray radiotherapy delivered through helical tomotherapy over 15 sessions, with a single dose of 2 Gy being administered five times a week. Concurrently, The dose is 4 mg of zoledronic acid administered intravenously once every 21 days. After treatment, the patient's nasal congestion was significantly relieved, the vision of the right eye improved, and the mandibular lesion was significantly reduced., Conclusions: Treatment with radiotherapy combined with zoledronic acid for our patient's inoperable osteolytic giant cell reparative granuloma adjacent to vital nerves and blood vessels was extremely effective and safe. This case report provides a reference for the management of this rare combination., (© 2024 Wiley Periodicals LLC.)

The outcomes of relapsed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) resistant to new drugs such as tyrosine kinase inhibitors, inotuzumab ozogamicin (InO) and blinatumomab are dismal. We treated two cases of Ph+ALL resistant to these drugs that achieved long-term survival after treatment with chimeric antigen receptor (CAR)-T cell therapy or a second allogeneic hematopoietic stem cell transplantation (HCT) with a sequential conditioning regimen. Case 1: A 15-year-old boy was diagnosed with Ph+ALL. Despite the second HCT after the treatment of ponatinib and blinatumomab, hematological relapse occurred. InO was ineffective and he was transferred to a CAR-T center. After the CAR-T cell therapy, negative measurable residual disease (MRD) was achieved and maintained for 38 months without maintenance therapy. Case 2: A 21-year-old man was diagnosed with Ph+ALL. Hematological relapse occurred after the first HCT. Despite of the treatment with InO, ponatinib, and blinatumomab, hematological remission was not achieved. The second HCT was performed using a sequential conditioning regimen with clofarabine. Negative MRD was subsequently achieved and maintained for 42 months without maintenance therapy. These strategies are suggestive and helpful to treat Ph+ALL resistant to multiple immunotherapies.

Hypertension is often linked with metabolic risk factors that share common pathophysiological pathways. Despite wide-spread availability of multiple drug classes, optimal blood pressure (BP) control remains challenging. Increased central sympathetic outflow is frequently neglected as a critical regulator of both circulatory and metabolic pathways and often remains unopposed therapeutically. Selective imidazoline receptor agonists (SIRAs) effectively reduce BP with a favorable side effect profile compared with older centrally acting antihypertensive drugs. Hard outcome data in hypertension, such as prevention of stroke, heart and kidney diseases, are not available with SIRAs. However, in direct comparisons, SIRAs were as effective as angiotensin-converting enzyme inhibitors, β-blockers, calcium channel blockers, and diuretics in lowering BP. Other beneficial effects on metabolic parameters in hypertensive patients with concomitant overweight and obesity have been documented with SIRAs. Here we review the existing evidence on the safety and efficacy of moxonidine, a widely available SIRA, compared with common antihypertensive agents and provide a consensus position statement based on inputs from 12 experts from Europe and Australia on SIRAs in hypertension management., (Copyright © 2024 The Author(s).

Progressive osteolysis can occur at the cement-bone interface of joint replacements and the associated loss of fixation can lead to clinical loosening. We previously developed a rat hemiarthroplasty model that exhibited progressive loss of fixation with the development of cement-bone gaps under the tibial tray that mimicked patterns found in human arthroplasty retrievals. Here we explored the ability of a bisphosphonate (zoledronic acid, ZA) to attenuate cement-bone osteolysis and maintain implant stability. Sprague-Dawley rats (n = 59) received a poly(methylmethacrylate) cemented tibial component and were followed for up to 12 weeks. Treatment groups included peri-operative administration of ZA (ZA group), administration of ZA at 6 weeks postop (late ZA group), or vehicle (Veh group). There was a 60% reduction in the rate of cement-bone gap formation for the ZA group (0.15 mm 3 /week) compared to Veh group (0.38 mm 3 /week, p = 0.016). Late ZA prevented further progression of gap formation but did not reverse bone loss to the level achieved in the ZA group. Micromotion from five times body weight toggle loading was positively correlated with cement-bone gap volume (p = 0.009) and negatively correlated with the amount of cement in the metaphysis (p = 0.005). Reduced new bone formation and enduring nonviable bone in the epiphysis for the ZA group were found. This suggests that low bone turnover in the epiphysis may suppress the early catabolic response due to implantation, thereby maintaining better fixation in the epiphysis. This preclinical model presents compelling supporting data documenting improved maintenance of the cement-bone fixation with the use of peri-operative bisphosphonates., (© 2024 Orthopaedic Research Society.)

Aim: To compare the efficacy of adding original moxonidine and its generics to previous ineffective antihypertensive therapy in patients with poorly controlled arterial hypertension (AH)., Material and Methods: This observational prospective non-randomized study included 120 patients with poorly controlled blood pressure on the previous antihypertensive therapy. All patients underwent clinical evaluation, including anthropometric and laboratory indexes, and 24-hour blood pressure monitoring (24-h BPM) at baseline and after 12 weeks of observation. Office systolic and diastolic blood pressure (SBP and DBP) and heart rate (HR) were recorded after 4 and 12 weeks of treatment. During the observation period, 4 equal groups were formed: group 1, Physiotens was added to the treatment; group 2, Moxonitex; group 3, Moxonidine SZ; and group 4, Moxonidine Canon. Statistical analysis was performed with the StatTech v.4.2.7 software (© OOO StatTech, Russia)., Results: After 4 weeks of therapy, the BP target was achieved significantly more frequently in group 1 (63% of patients) compared to groups 2 (36.7% of patients), 3 (16.7% of patients), and 4 (16.7% of patients) (p&lt;0.05). At 12 weeks, office SBP, DBP, and HR were significantly decreased in all groups, but the decrease was significantly greater in group 1. The therapy was associated with a more pronounced decrease in all studied 24-h BPM parameters in the Physiotens group than in other groups, as well as with a significantly more frequent normalization of the 24-h BP profile, in 66.7% of patients vs. 46.7%, 33.4%, and 23.2% of patients in groups 2, 3, and 4, respectively., Conclusion: The treatment with original moxonidine demonstrated advantages over generic drugs in terms of achieving the BP goal, reducing office BP and HR, and improving 24-h BPM parameters.

Oral and gut microbiota can interact with the host by producing a diverse range of bioactive metabolites, thereby influencing overall host health. Imidazole propionate (ImP), a histidine-derived metabolite produced by microbes associated with diabetes mellitus, has attracted considerable attention on account of its roles in metabolic and cardiovascular diseases. In this article, we review the metabolic pathways of ImP, as well as its roles and therapeutic potential in type 2 diabetes mellitus and cardiovascular diseases. Future research should focus on key enzymes and regulatory factors in the ImP metabolic pathway, interactions with other metabolites, and conduct large-scale clinical studies to gain a more comprehensive understanding of the role of ImP in diverse populations and disease contexts. Moreover, targeted interventions against ImP could provide novel strategies for preventing and treating metabolic and cardiovascular diseases., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

This study aimed to evaluate the effects of dabrafenib and/or trametinib therapy in BRAF v600-mutant glioma treatment. PubMed, the Cochrane Library, EMBASE and Web of Science were searched from inception to Sep 2023. Inclusion criteria were designed based on the PICO principle to select relevant articles. Search keywords included 'dabrafenib', 'trametinib', 'glioma' and other related keywords. Outcomes included overall survival (OS), progression-free survival (PFS), adverse events (AEs), and death events. Methodological index for non-randomized studies (MINORS) was used to assess the methodological quality. Stata 14.0 was selected to perform the Cochrane Q and I 2 statistics to test the heterogeneity among all studies. As for publication bias assessment and sensitivity analysis, the funnel plot, Egger regression test, Begg test, and trim and fill method were selected. Including 8 studies for meta-analysis. The pooled results of the single-arm trials showed that the median PFS and median OS after treatment were 6.10 months and 22.73 months, respectively. Notably, this study found a high incidence of AEs and death events of 50% and 43% after treatment. All the above findings were statistically significant. Also, this study statistically supported the advantage of disease response improvement after the combination therapy in BRAF v600-mutant glioma patients, which were shown as a pooled rate of PR (30%), a pooled rate of CR (18%), and a pooled rate of ORR (39%). And the AE rate was lower in the monotherapy group (AE: 25%) than in the combination treatment group (AE: 60%). Sensitivity analysis indicated that all the results were robust. Based on current literature outcomes, dabrafenib and/or trametinib may lead to the median PFS of 6.10 months and median OS as 22.73 months for BRAF v600-mutant glioma patients, and the safety of monotherapy is better than that of combination therapy. This conclusion needs to be treated with caution and further verified., (© 2024. The Author(s).)

Toll-like receptor (TLR) agonists are being developed as anti-cancer therapeutics due to their potent immunostimulatory properties. However, clinical trials testing TLR agonists as monotherapy have often failed to demonstrate significant improvement over standard of care. We hypothesized that the anti-cancer efficacy of TLR agonist immunotherapy could be improved by combinatorial approaches. To prevent increased toxicity, often seen with systemic combination therapies, we developed a hydrogel to deliver TLR agonist combinations at low doses, locally, during cancer debulking surgery. Using tumor models of WEHI 164 and bilateral M3-9-M sarcoma and CT26 colon carcinoma, we assessed the efficacy of pairwise combinations of poly(I:C), R848, and CpG in controlling local and distant tumor growth. We show that combination of the TLR3 agonist poly(I:C) and TLR7/8 agonist R848 drives anti-tumor immunity against local and distant tumors. In addition, combination of local poly(I:C) and R848 sensitized tumors to systemic immune checkpoint blockade, improving tumor control. Mechanistically, we demonstrate that local therapy with poly(I:C) and R848 recruits inflammatory monocytes to the tumor draining lymph nodes early in the anti-tumor response. Finally, we provide proof of concept for intraoperative delivery of poly(I:C) and R848 together via a surgically applicable biodegradable hydrogel., Competing Interests: The authors declare a patent application related to the hydrogel biomaterial used in this work., (© 2024 The Author(s).

Cardiotoxicity associated with chemotherapy has gradually become the major cause of death in cancer patients. The development of bifunctional drugs with both cardioprotective and antitumor effects has become the future direction. HDAC6 plays important roles in the progression, treatment, and prognosis of cancer and cardiovascular diseases, but bifunctional inhibitors have not been reported. Herein, structure-activity relationship studies driven by pharmacophore-based remodification and fragment-based design were performed to yield highly potent HDAC6 inhibitor I-c4 containing imidazo[1,2- a ]pyridine. Importantly, I-c4 effectively suppressed the growth of MGC-803 xenografts in vitro and in vivo by inhibiting the deacetylation pathway without causing myocardial damage after long-term administration. Meanwhile, I-c4 could mitigate severe myocardial damage against H 2 O 2 or myocardial ischemia/reperfusion in vitro and in vivo. Further studies revealed that the cardioprotective effect of I-c4 was associated with reduction of inflammatory cytokines. Taken together, I-c4 may represent a novel lead compound for further development of an anticarcinogen with a cardioprotective effect.

Inpatient zoledronic acid (IP-ZA) administered during the initial fracture hospitalization significantly improves the osteoporosis treatment rate. Clinical outcomes of IP-ZA after hip fracture remain uncertain. Here we report a cohort study that emulated a randomized controlled trial using real-world data and evaluated the risk of all-cause-mortality and radiologically confirmed subsequent new fractures among patients hospitalized for a hip fracture who had received IP-ZA as compared with propensity-matched controls. A total of 654 patients who had received IP-ZA and 6877 controls (for whom anti-osteoporosis treatment was indicated but no IP-ZA started during index hospitalization) were included in the study. The primary cohort comprised 652 IP-ZA patients (IP-ZA group) and 1926 matched controls (untreated group), with 71.7% female 92.1% White participants, with a mean age of 80.9 years. Cumulative all-cause mortality over the 24-month follow-up for the IP-ZA group was 12.3% and 20.7% for the untreated group (hazard ratio [HR], 0.62; 95% CI, 0.49-0.78, p < .001). A total of 585 (89.7%) patients in IP-ZA group received only a single dose of ZA during the 24 months, and the death rate of this single dose group was 13.3%, which was significantly lower than that of the untreated group (HR, 0.70; 95% CI, 0.55-0.89, p = .003). Rates of radiologically confirmed cumulative subsequent new vertebral fractures were 2.0% in the IP-ZA group and 5.4% in the untreated group (HR, 0.40; 95% CI, 0.22-0.71, p = .001). A similarly lower rate of new vertebral fractures was seen in the single dose subgroup (1.9% vs 5.4%; HR, 0.44; 95% 0.24-0.82, p = .008). IP-ZA, administered during the initial hospitalization for hip fracture, was associated with lower all-cause-mortality and risk of radiologically confirmed subsequent new vertebral fractures, and thus offers a mechanism to narrow the treatment gap in patients having sustained a hip fragility fracture., (© The Author(s) 2024.
