Background: A primary goal in treating obstructive hypertrophic cardiomyopathy (oHCM) is to improve patients' health status: their symptoms, function, and quality of life. The health status benefits of aficamten, a novel cardiac myosin inhibitor, have not been comprehensively described., Objectives: This study sought to determine the effect of aficamten on patient-reported health status, including symptoms of fatigue, shortness of breath, chest pain, physical and social limitations, and quality of life., Methods: SEQUOIA-HCM (Phase 3 Trial to Evaluate the Efficacy and Safety of Aficamten Compared to Placebo in Adults With Symptomatic oHCM) randomized symptomatic adults with oHCM to 24 weeks of aficamten (n = 142) or placebo (n = 140), followed by a 4-week washout. The Kansas City Cardiomyopathy Questionnaire (KCCQ) and Seattle Angina Questionnaire 7-item (SAQ7) were serially administered. Changes in mean KCCQ-Overall Summary Score (KCCQ-OSS) and SAQ7-Summary Score (SAQ7-SS) from baseline to 24 weeks and following treatment withdrawal were compared using linear regression adjusted for baseline scores and randomization strata. Proportions of patients with clinically important changes were compared., Results: Among 282 participants, the mean age was 59 ± 13 years, 115 (41%) were female, and 223 (79%) were White. Baseline KCCQ-OSS (69.3 ± 20.1 vs 67.3 ± 18.8) and SAQ7-SS (72.0 ± 21.0 vs 72.4 ± 18.3) were similar between aficamten and placebo groups. Treatment with aficamten, compared with placebo, improved both the mean KCCQ-OSS (13.3 ± 16.3 vs 6.1 ± 12.6; mean difference: 7.9; 95% CI: 4.8-11.0; P < 0.001) and SAQ7-SS (11.6 ± 17.4 vs 3.8 ± 14.4; mean difference: 7.8; 95% CI: 4.7-11.0; P < 0.001) at 24 weeks, with benefits emerging within 4 weeks. No heterogeneity in treatment effect was found across subgroups. A much larger proportion of participants experienced a very large health status improvement (≥20 points) with aficamten vs placebo (KCCQ-OSS: 29.7% vs 12.4%, number needed to treat: 5.8; SAQ7-SS: 31.2% vs 13.9%, number needed to treat: 5.8). Participants' health status worsened significantly more after withdrawal from aficamten than placebo (KCCQ-OSS: -16.2 ± 19.0 vs -3.0 ± 9.6; P < 0.001; SAQ7-SS: -17.4 ± 21.4 vs -2.5 ± 13.3), further confirming a causal effect of aficamten., Conclusions: In patients with symptomatic oHCM, treatment with aficamten resulted in markedly improved health status, including significant improvement in chest pain-related health status, than placebo.

Preparing stable n-type flexible single-walled carbon nanotube (SWCNT)-based thermoelectric films with high thermoelectric (TE) performance is desirable for self-powering wearable electronics but remains a challenge. Here, the interface regulation and thermoelectric enhancement mechanism of ferrocene derivatives on polyethylenimine/single-walled carbon nanotube (PEI/SWCNT) composite films have been explored by doping ferrocene derivatives (f-Fc-OH) into PEI/SWCNT films. The results show that the introduction of f-Fc-OH leads to the formation of "thorn" structures on the surfaces of SWCNT bundles via hydrophilic and hydrophobic interactions, the generated energy-filtering effect improves the thermoelectric properties of the PEI/SWCNT film, and the f-Fc-OH-doped PEI/SWCNT (f-Fc-OH/PEI/SWCNT) achieves the highest room-temperature power factor of 182.22 ± 8.60 μW m -1 K -2 with a Seebeck coefficient of -64.28 ± 0.96 μV K -1 and the corresponding ZT value of 4.69 × 10 -3 . The Seebeck coefficient retention ratio of the f-Fc-OH/PEI/SWCNT nearly remained 68% after being exposed to air for 3672 h, while the PEI/SWCNT film changed from n-type to p-type after being exposed to air for about 432 h. In addition, the temperature-dependent thermoelectric properties show that the f-Fc-OH/PEI/SWCNT achieves a high power factor of 334.57 μW m -1 K -2 at 353 K. Finally, a flexible TE module consisting of seven pairs of p-n junctions is assembled using the optimum composite film, which produces an open-circuit voltage of 42 mV and a maximum output power of 4.32 μW at a temperature gradient of 60 K. Therefore, this work provides guidance for preparing stable n-type SWCNT-based composite films with enhanced thermoelectric properties, which have potential applications in flexible generators and wearable electronic devices.

Rotator cuff tendinopathy is a common musculoskeletal disorder with limited pharmacological treatment strategies. This study aimed to investigate tenocytes' functional in vitro response from a ruptured supraspinatus tendon to suramin administration and to elucidate whether suramin can enhance tendon repair and modulate the inflammatory response to injury. Tenocytes were obtained from human supraspinatus tendons (n = 6). We investigated the effect of suramin on LPS-induced inflammatory responses and the underlying molecular mechanisms in THP-1 macrophages. Suramin enhanced the proliferation, cell viability, and migration of tenocytes. It also increased the protein expression of PCNA and Ki-67. Suramin-treated tenocytes exhibited increased expression of COL1A1, COL3A1, TNC, SCX, and VEGF. Suramin significantly reduced LPS-induced iNOS, COX2 synthesis, inflammatory cytokine TNF-α production, and inflammatory signaling by influencing the NF-κB pathways in THP-1 cells. Our results suggest that suramin holds great promise as a therapeutic option for treating rotator cuff tendinopathy., (© 2024 Orthopaedic Research Society.)

Background: Patients with heart failure (HF) with mildly reduced or preserved ejection fraction face heightened long-term risks of morbidity and mortality. The sodium glucose-co-transporter-2 inhibitors (SGLT2i) and the non-steroidal mineralocorticoid receptor antagonist (MRA) finerenone have both been shown to reduce the risk of cardiovascular events in this population, but the effects of their combined use are not known., Methods: FINEARTS-HF was a randomized, double-blind, placebo-controlled trial of finerenone in patients with HF and left ventricular ejection fraction (LVEF) ≥40%. Baseline SGLT2i use was a prespecified subgroup. The primary outcome was a composite of total (first and recurrent) worsening HF events and cardiovascular death. We first assessed for evidence of treatment heterogeneity based on baseline SGLT2i use. We further examined SGLT2i uptake during the trial and evaluated the treatment effects of finerenone accounting for baseline and during trial use of SGLT2i in time-varying analyses., Results: Among 6,001 participants, 817 (13.6%) were treated with an SGLT2i at baseline. During 2.6-years median follow-up, treatment with finerenone similarly reduced the risk of the primary outcome in participants treated with an SGLT2i (rate ratio 0.83; 95% confidence interval 0.60 to 1.16) and without an SGLT2i at baseline (rate ratio 0.85; 95% confidence interval 0.74 to 0.98); P interaction =0.76. In follow-up, 980 participants initiated SGLT2i, which was less frequent in the finerenone arm compared with placebo (17.7% vs. 20.1%; hazard ratio 0.86; confidence interval 0.76 to 0.97). Time-updated analyses accounting for baseline and subsequent use of SGLT2i did not meaningfully alter the treatment effects of finerenone on the primary endpoint., Conclusions: The treatment benefits of the non-steroidal MRA finerenone were observed irrespective of concomitant use of an SGLT2i. These data suggest that the combined use of SGLT2i and a non-steroidal MRA may provide additive protection against cardiovascular events in patients with HF with mildly reduced or preserved ejection fraction.

The significance of anterior cruciate ligament (ACL) remnants during reconstruction remains unclear. Co-culturing ACL remnant cells and bone marrow stromal cells (BMSCs) may reduce apoptosis and enhance hamstring tendon activity. This study investigated whether extracellular vesicles (EVs), which facilitate cell-cell interactions, act as the active components, improving graft maturation in this co-culture. The effects of EVs on cell viability, proliferation, migration and gene expression in the rabbit ACL remnant cells and BMSCs were assessed using control (BMSC-only culture), co-culture (ACL remnant cells and BMSCs, CM) and co-culture without EVs (CM ∆ EVs) media. EVs were isolated from control (BMSC-EV) and co-culture (CM-EV) media and characterized. CM significantly enhanced the proliferation, migration and expression of transforming growth factor (TGF-β)-, vascular endothelial growth factor (VEGF)-, collagen synthesis- and tenogenesis-related genes. However, CM-induced effects were reversed by the CM ∆ EVs treatment. CM-EV treatment exhibited higher potential to enhance proliferation, migration and gene expression in the ACL remnant cells and BMSCs than BMSC-EV and non-EV treatments. In conclusion, EVs, secreted under the coexistence of ACL remnant cells and BMSCs, primarily increase the cell viability, proliferation, migration and gene expression of collagen synthesis-, TGF-β-, VEGF- and tenogenesis-related genes in both cell types., (© 2024 The Author(s).

The microplastics in aquatic ecosystems pose a serious threat to ecological security and environmental health, which have received widespread attention. To reveal the response of a water- Vallisneria natans -sediment system to microplastics exposure, the V. natans was exposed to polyethylene microplastics （PE-MPs） with different mass fractions （1%-5%, sediment wet mass fraction）, and the effects of PE-MPs on the physiochemical indicators of water quality, morphological characteristics of submerged plants, physiological characters, antioxidant system, and microbial community structure in sediments were studied respectively. The results showed that the physiochemical properties of the water body were not significantly changed in the PE-MPs treatment group, whereas the plant height, oxidative stress index, and antioxidant system were significantly inhibited. For the plant height, the 1% PE-MPs treatment group height was only 47.44% of that in the control group. Chlorophyll a content was 81.04% of that in the control group, and the activities of catalase （CAT）, malondialdehyde （MDA）, and peroxidase （POD） increased by 233.70%, 117.82%, and 61.62%, respectively. Different mass fractions of PE-MPs had a certain impact on microbial community structure in sediments. The above results are helpful to improve the evaluation system of PE-MPs ecological risk in the water-submerged plant-sediment system.

Background: Aficamten, a novel cardiac myosin inhibitor, reversibly reduces cardiac hypercontractility in obstructive hypertrophic cardiomyopathy. We present a prespecified analysis of the pharmacokinetics, pharmacodynamics, and safety of aficamten in SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM)., Methods and Results: A total of 282 patients with obstructive hypertrophic cardiomyopathy were randomized 1:1 to daily aficamten (5-20 mg) or placebo between February 1, 2022, and May 15, 2023. Aficamten dosing targeted the lowest effective dose for achieving site-interpreted Valsalva left ventricular outflow tract gradient <30 mm Hg with left ventricular ejection fraction (LVEF) ≥50%. End points were evaluated during titration (day 1 to week 8), maintenance (weeks 8-24), and washout (weeks 24-28), and included major adverse cardiac events, new-onset atrial fibrillation, implantable cardioverter-defibrillator discharges, LVEF <50%, and treatment-emergent adverse events. At week 8, 3.6%, 12.9%, 35%, and 48.6% of patients achieved 5-, 10-, 15-, and 20-mg doses, respectively. Baseline characteristics were similar across groups. Aficamten concentration increased by dose and remained stable during maintenance. During the treatment period, LVEF decreased by -0.9% (95% CI, -1.3 to -0.6) per 100 ng/mL aficamten exposure. Seven (4.9%) patients taking aficamten underwent per-protocol dose reduction for site-interpreted LVEF <50%. There were no treatment interruptions or heart failure worsening for LVEF <50%. No major adverse cardiovascular events were associated with aficamten, and treatment-emergent adverse events were similar between treatment groups, including atrial fibrillation., Conclusions: A site-based dosing algorithm targeting the lowest effective aficamten dose reduced left ventricular outflow tract gradient with a favorable safety profile throughout SEQUOIA-HCM., Registration: URL: https://www.clinicaltrials.gov; Unique Identifier: NCT05186818.

In layered Li-rich materials, over stoichiometric Li forms an ordered occupation of LiTM 6 in transition metal (TM) layer, showing a honeycomb superstructure along [001] direction. At the atomic scale, the instability of the superstructure at high voltage is the root cause of problems such as capacity/voltage decay of Li-rich materials. Here a Li-rich material with a high Li/Ni disorder is reported, these interlayer Ni atoms locate above the honeycomb superstructure and share adjacent O coordination with honeycomb TM. These Ni─O bonds act as cable-stayed bridge to the honeycomb plane, and improve the high-voltage stability. The cable-stayed honeycomb superstructure is confirmed by in situ X-ray diffraction to have a unique cell evolution mechanism that it can alleviate interlaminar lattice strain by promoting in-plane expansion along a-axis and inhibiting c-axis stretching. Electrochemical tests also demonstrate significantly improved long cycle performance after 500 cycles (86% for Li-rich/Li half cell and 82% for Li-rich/Si-C full cell) and reduced irreversible oxygen release. This work proves the feasibility of achieving outstanding stability of lithium-rich materials through superstructure regulation and provides new insights for the development of the next-generation high-energy-density cathodes., (© 2024 Wiley‐VCH GmbH.)

Nowadays, numerous studies have developed risk prediction models for sarcopenia in dialysis patients. However, the quality and performance of these models have not been integrated. The purpose of our study is to provide a comprehensive overview of the current risk prediction models for sarcopenia in dialysis patients and to offer a reference for the development of high-quality prediction models. Ten electronic databases were searched from inception to March 8, 2024. Two researchers independently assessed the risk of bias and applicability of the studies, and used Revman, 5.4, software to conduct a meta-analysis of common predictors in the models. A total of 12 studies described 13 risk prediction models for dialysis patients with sarcopenia. In dialysis patients, the prevalence of sarcopenia ranged from 6.60% to 63.73%. The area under curve (AUC) of the 13 models ranged from 0.776 to 0.945. Only six models (AUC ranging from 0.73 to 0.832) were internally validated, while two were externally evaluated (AUC ranging from 0.913 to 0.955). Most studies had a high risk of bias. The most common effective predictors in the models were age, body mass index, muscle circumference, and C-reactive protein. Our study suggests that developing a prediction model for the onset of sarcopenia in dialysis patients requires a rigorous design scheme, and future verification methods will necessitate multicenter external validation., (Copyright © 2024 National Kidney Foundation, Inc.

Background: Patients who sustain an acute myocardial infarction (AMI), including ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), remain at high risk for heart failure (HF), coronary events, and death. Angiotensin-converting enzyme inhibitors have been shown to significantly decrease the risk for cardiovascular events in both STEMI and NSTEMI patients., Objectives: The objectives were to determine whether angiotensin-receptor blockade and neprilysin inhibition with sacubitril/valsartan, compared with ramipril, has impact on reducing cardiovascular events according to the type of AMI., Methods: The PARADISE-MI (Prospective ARNI versus ACE inhibitor trial to DetermIne Superiority in reducing heart failure Events after Myocardial Infarction) trial enrolled patients with AMI complicated by left ventricular dysfunction and/or pulmonary congestion and at least 1 risk-enhancing factor. Patients were randomized to either sacubitril/valsartan or ramipril. The primary endpoint was death from cardiovascular causes or incident HF. In this prespecified analysis, we stratified patients according to AMI type., Results: Of 5,661 enrolled patients, 4,291 (75.8%) had STEMI. These patients were younger and had fewer comorbidities and cardiovascular risk factors than NSTEMI patients. After adjustment for potential confounders, the risk for the primary outcome was marginally higher in NSTEMI vs STEMI patients (adjusted HR: 1.19; 95% CI: 1.00-1.41), with borderline statistical significance (P = 0.05). The primary composite outcome occurred at similar rates in patients randomized to sacubitril/valsartan vs ramipril in STEMI (10% vs 12%; HR: 0.87; 95% CI: 0.73-1.04; P = 0.13) and NSTEMI patients (17% vs 17%; HR: 0.97; 95% CI: 0.75-1.25; P = 0.80; P interaction = 0.53)., Conclusions: Compared with ramipril, sacubitril/valsartan did not significantly decrease the risk for cardiovascular death and HF in patients with AMI complicated by left ventricular dysfunction, irrespective of the type of AMI.

Background: In our previous study, we provided evidence that Astragalus mongholicus Bunge(AM) and its extracts possess a protective capability against radiation-induced damage, potentially mediated through the reduction of reactive oxygen species (ROS) and nitric oxide (NO). However, we were pleasantly surprised to discover during our experimentation that AM not only offers protection against radiation damage but also exhibits a radiation sensitization effect. This effect may be attributed to a specific small molecule present in AM known as ononin. Currently, radiation sensitizers are predominantly found in nitrazole drugs and nanomaterials, with no existing reports on the radiation sensitization properties of ononin, nor its underlying mechanism., Purpose: This study aims to investigate the sensitization effect of the small molecule ononin derived from AM on lung cancer radiotherapy, elucidating its specific molecular mechanism of action. Additionally, the safety profile of combining astragalus small molecule ononin with radiation therapy will be evaluated., Methods: The effective concentration of ononin was determined through cell survival experiments, and the impact of ononin combined with varying doses of radiation on lung cancer cells was observed using CCK-8 and cell cloning experiments. The apoptotic effect of ononin combined with radiation on lung cancer cells was assessed using Hochester staining, flow cytometry, and WB assay. Additionally, WB and immunofluorescence analysis were conducted to investigate the influence of ononin on HIF-1α/VEGF pathway. Furthermore, Molecular Dynamics Simulation was employed to validate the targeted binding ability of ononin and HIF-1α. A lung cancer cell line was established to investigate the effects of knockdown and overexpression of HIF-1α. Subsequently, the experiment was repeated using tumor bearing nude mice and C57BL/6 mouse models in an in vivo study. Tumor volume was measured using a vernier caliper, while HE, immunohistochemistry, and immunofluorescence techniques were employed to observe the effects of ononin combined with radiation on tumor morphology, proliferation, and apoptosis. Additionally, Immunofluorescence was employed to examine the impact of ononin on HIF-1α/VEGF pathway in vivo, and its effect on liver function in mice was assessed through biochemistry analysis., Results: At a concentration of 25 μM, ononin did not affect the proliferation of lung epithelial cells but inhibited the survival of lung cancer cells. In vitro experiments demonstrated that the combination of ononin and radiation could effectively inhibit the growth of lung cancer cells, induce apoptosis, and suppress the excessive activation of the Hypoxia inducible factor 1 alpha/Vascular endothelial growth factor pathway. In vivo experiments showed that the combination of ononin and radiation reduced the size and proliferation of lung cancer tumors, promoted cancer cell apoptosis, mitigated abnormal activation of the Hypoxia inducible factor 1 alpha pathway, and protected against liver function damage., Conclusion: This study provides evidence that the combination of AM and its small molecule ononin can enhance the sensitivity of lung cancer to radiation. Additionally, it has been observed that this combination can specifically target HIF-1α and exert its effects. Notably, ononin exhibits the unique ability to protect liver function from damage while simultaneously enhancing the tumor-killing effects of radiation, thereby demonstrating a synergistic and detoxifying role in tumor radiotherapy. These findings contribute to the establishment of a solid basis for the development of novel radiation sensitizers derived from traditional Chinese medicine., Competing Interests: Declaration of competing interest We declare that we have no financial and personal relationships with other people or organizations that can inappropriately influence our work, there is no professional or other personal interest of any nature or kind in any product, service and/or company that could be construed as influencing the position presented in, or the review of, the manuscript entitled., (Copyright © 2023 The Author(s).

Background: Tricuspid regurgitation (TR) is common and is associated with poor outcomes in patients with heart failure (HF). However, data with adjudicated events from fully characterized patients with heart failure with reduced ejection fraction (HFrEF) are lacking., Objectives: This study sought to explore the association between mild or moderate/severe TR and clinical outcomes of patients with HFrEF., Methods: GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) was a double-blind, placebo-controlled randomized trial comparing omecamtiv mecarbil vs placebo in patients with symptomatic HFrEF., Results: Among the 8,232 patients analyzed in the GALACTIC-HF trial, 8,180 (99%) had data regarding baseline TR (none: n = 6,476 [79%], mild: n = 919 [11%], and moderate/severe: n = 785 [10%]). The primary composite outcome of a first HF event or cardiovascular death occurred in 2,368 (36.6%) patients with no TR, 353 (38.4%) patients with mild TR, and 389 (49.6%) patients with moderate/severe TR. Moderate/severe TR was independently associated with a higher relative risk of the primary composite outcome compared with either no TR (adjusted HR: 1.12 [95% CI: 1.01-1.26]; P = 0.046) or no/mild TR (adjusted HR: 1.14 [95% CI: 1.02-1.27]; P = 0.025) driven predominantly by HF events. The association between moderate/severe TR and clinical outcomes was more pronounced in outpatients with worse renal function, higher left ventricular ejection fraction, and lower N-terminal pro-B-type natriuretic peptide and bilirubin levels. The beneficial treatment effect of omecamtiv mecarbil vs placebo on clinical outcomes was not modified by TR., Conclusions: In symptomatic patients with HFrEF, baseline moderate/severe TR was independently associated with cardiovascular death or HF events driven predominantly by HF events. The beneficial treatment effect of omecamtiv mecarbil on the primary outcome was not modified by TR., Competing Interests: Funding Support and Author Disclosures Dr Adamo has received specker honoraria from Abbott Vascular.

The contamination of arable land with heavy metals, such as Cd, is a serious concern worldwide. Intercropping with Cd accumulators can be used for efficient safe crop production and phytoremediation of Cd-contaminated soil. However, the effect of intercropping on Cd uptake by main crops and accumulators varies among plant combinations. Rhizosphere interaction may mediate Cd uptake by intercropped plants, but the mechanism is unclear. Thus, in the present study, we aimed to examine the effect of rhizosphere interaction on Cd uptake by intercropping rice (Oryza sativa L.) with mugwort (Artemisia argyi Levl. et Vant.) in Cd-contaminated paddy soil. We grew O. sativa and A. argyi in pots designed to allow different levels of interaction: complete root interaction (no barrier), partial root interaction (nylon mesh barrier), and no root interaction (plastic film barrier). Our results indicated that both complete and partial root interaction increased the shoot and root mass of A. argyi, but did not decrease the shoot, root, and grain mass of O. sativa. Interspecific root interaction significantly increased the Cd content in the shoots, roots, and grains of O. sativa and the shoots of A. argyi. Increased content of total organic acids in the rhizosphere, which increased the content of available Cd, was a possible mechanism of increased Cd uptake in both plants under interspecific root interaction. Our findings demonstrate that an intercropping system can extract more Cd from contaminated soil than a monocropping system of either A. argyi or O. sativa. However, the intercropping system did not facilitate safe crop production because it substantially increased grain Cd content in O. sativa., 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 © 2023 The Authors.

Background: In the Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure (GALACTIC-HF) trial, omecamtiv mecarbil, compared with placebo, reduced the risk of worsening heart failure (HF) events, or cardiovascular death in patients with HF and reduced ejection fraction. The primary aim of this prespecified analysis was to evaluate the safety and efficacy of omecamtiv mecarbil by randomization setting, that is, whether participants were enrolled as outpatients or inpatients., Methods and Results: Patients were randomized either during a HF hospitalization or as an outpatient, within one year of a worsening HF event (hospitalization or emergency department visit). The primary outcome was a composite of worsening HF event (HF hospitalization or an urgent emergency department or clinic visit) or cardiovascular death. Of the 8232 patients analyzed, 2084 (25%) were hospitalized at randomization. Hospitalized patients had higher N-terminal prohormone of B-type natriuretic peptide concentrations, lower systolic blood pressure, reported more symptoms, and were less frequently treated with a renin-angiotensin system blocker or a beta-blocker than outpatients. The rate (per 100 person-years) of the primary outcome was higher in hospitalized patients (placebo group = 38.3/100 person-years) than in outpatients (23.1/100 person-years); adjusted hazard ratio 1.21 (95% confidence interval 1.12-1.31). The effect of omecamtiv mecarbil versus placebo on the primary outcome was similar in hospitalized patients (hazard ratio 0.89, 95% confidence interval 0.78-1.01) and outpatients (hazard ratio 0.94, 95% confidence interval 0.86-1.02) (interaction P = .51)., Conclusions: Hospitalized patients with HF with reduced ejection fraction had a higher rate of the primary outcome than outpatients. Omecamtiv mecarbil decreased the risk of the primary outcome both when initiated in hospitalized patients and in outpatients., Competing Interests: Declaration of Competing Interest K.F.D. has received financial support to attend educational meetings from Cytokinetics during the conduct of the study, personal fees from AstraZeneca, consulting fees from Us2.ai and research grants to his institution from AstraZeneca and Boehringer Ingelheim outside the submitted work.

Background: The combination of tislelizumab and gemcitabine plus cisplatin (GP) in the first-line treatment of patients with recurrent or metastatic nasopharyngeal carcinoma (R/M NPC) has yielded significant results. However, it is not clear whether this treatment option is cost-effective in China. The purpose of this study is to evaluate the cost-effectiveness of tislelizumab plus GP for the first-line treatment of R/M NPC from the perspective of the Chinese healthcare system., Methods: A partitioned survival model with three discrete health states was constructed to evaluate the cost-effectiveness of tislelizumab plus GP versus GP in patients with R/M NPC. The target population enrolled in the RATIONALE-309 trial had previously not treated for R/M NPC. Drug costs were obtained from relevant databases, and the remaining cost and health utility data were collected from the literature. The main outcomes include the expected life years, quality-adjusted life years (QALYs), total cost, and incremental cost-benefit ratio (ICER)., Results: The tislelizumab plus GP regimen produced an additional cost ($18392.76) and additional 1.57 QALYs compared with GP used alone. The ICER was $18392.75/QALYs. Sensitivity analysis showed that the analysis was robust and the utility of PD status was most sensitive to the model results. The possibility of tislelizumab plus GP being cost-effective at the willingness-to-pay (WTP) threshold of $37 653/QALY was 99.8%. Subgroup analysis showed that high PD-L1 expression had little impact on the ICER of this regimen., Conclusion: In patients with R/M NPC, the regimen of tislelizumab plus GP, as the first-line treatment, is more cost-effective than the GP regimen in China., (© 2023 The Authors.

Aim: It is unknown whether safety and clinical endpoints by use of sacubitril/valsartan (an angiotensin receptor-neprilysin inhibitor [ARNI]) are affected by mineralocorticoid receptor antagonists (MRA) in high-risk myocardial infarction (MI) patients. The aim of this study was to examine whether MRA modifies safety and clinical endpoints by use of sacubitril/valsartan in patients with a MI and left ventricular systolic dysfunction (LVSD) and/or pulmonary congestion., Methods and Results: Patients (n = 5661) included in the PARADISE MI trial (Prospective ARNI vs. ACE Inhibitor Trial to Determine Superiority in Reducing Heart Failure Events After MI) were stratified according to MRA. Primary outcomes in this substudy were worsening heart failure or cardiovascular death. Safety was defined as symptomatic hypotension, hyperkalaemia >5.5 mmol/L, or permanent drug discontinuation. A total of 2338 patients (41%) were treated with MRA. Safety of ARNI compared to ramipril was not altered significantly by ± MRA, and both groups had similar increase in symptomatic hypotension with ARNI. In patients taking MRA, the risk of hyperkalaemia or permanent drug discontinuation was not significantly altered by ARNI (p > 0.05 for all comparisons). The effect of ARNI compared with ramipril was similar in those who were and were not taking MRA (hazard ratio [HR] MRA 0.96, 95% confidence interval [CI] 0.77-1.19 and HR MRA- 0.87, 95% CI 0.71-1.05, for the primary endpoint; p = 0.51 for interaction [Clinical Endpoint Committee adjudicated]); similar findings were observed if investigator-reported endpoints were evaluated (p = 0.61 for interaction)., Conclusions: Use of a MRA did not modify safety or clinical endpoints related to initiation of ARNI compared to ramipril in the post-MI setting in patients with LVSD and/or congestion., (© 2023 European Society of Cardiology.)

Background: Apparent treatment-resistant hypertension (aTRH) is prevalent and associated with adverse outcomes in heart failure with mildly reduced or preserved ejection fraction. Less is known about the potential role of sodium-glucose co-transporter 2 inhibition in this high-risk population. In this post hoc analysis of the DELIVER trial (Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure), we evaluated clinical profiles and treatment effects of dapagliflozin among participants with aTRH., Methods: DELIVER participants were categorized on the basis of baseline blood pressure (BP), with aTRH defined as BP ≥140/90 mm Hg (≥130/80 mm Hg if diabetes) despite treatment with 3 antihypertensive drugs including a diuretic. Nonresistant hypertension was defined as BP above threshold but not meeting aTRH criteria. Controlled BP was defined as BP under threshold. Incidence of the primary outcome (cardiovascular death or worsening heart failure event), key secondary outcomes, and safety events was assessed by baseline BP category., Results: Among 6263 DELIVER participants, 3766 (60.1%) had controlled BP, 1779 (28.4%) had nonresistant hypertension, and 718 (11.5%) had aTRH at baseline. Participants with aTRH had more cardiometabolic comorbidities and tended to have higher left ventricular ejection fraction and worse kidney function. Rates of the primary outcome were 8.7 per 100 patient-years in those with controlled BP, 8.5 per 100 patient-years in the nonresistant hypertension group, and 9.5 per 100 patient-years in the aTRH group. Relative treatment benefits of dapagliflozin versus placebo on the primary outcome were consistent across BP categories ( P interaction =0.114). Participants with aTRH exhibited the greatest absolute reduction in the rate of primary events with dapagliflozin (4.1 per 100 patient-years) compared with nonresistant hypertension (2.7 per 100 patient-years) and controlled BP (0.8 per 100 patient-years). Irrespective of assigned treatment, participants with aTRH experienced a higher rate of reported vascular events, including myocardial infarction and stroke, over study follow-up. Dapagliflozin modestly reduced systolic BP (by ≈1 to 3 mm Hg) without increasing risk of hypotension, hypovolemia, or other serious adverse events, irrespective of BP category, but did not improve the proportion of participants with aTRH attaining goal BP over time., Conclusions: aTRH was identified in >1 in 10 patients with heart failure and left ventricular ejection fraction >40% in DELIVER. Dapagliflozin consistently improved clinical outcomes and was well-tolerated, including among those with aTRH., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03619213., Competing Interests: Disclosures Dr Vaduganathan has received research grant support, served on advisory boards, or had speaker engagements with American Regent, Amgen, AstraZeneca, Bayer AG, Baxter Healthcare, Boehringer Ingelheim, Chiesi, Cytokinetics, Lexicon Pharmaceuticals, Merck, Novartis, Novo Nordisk, Pharmacosmos, Relypsa, Roche Diagnostics, Sanofi, and Tricog Health, and participates on clinical trial committees for studies sponsored by AstraZeneca, Galmed, Novartis, Bayer AG, Occlutech, and Impulse Dynamics.

Objectives: To observe the effects of acupoint application with turmeric blistering moxibustion plaster on pain, shoulder range of motion (ROM) and upper limb motor function in the patients with post-stroke hemiplegic shoulder pain (PSHSP)., Methods: Eighty-two patients with PSHSP were randomly divided into an observation group (41 cases, 1 case was eliminated, 4 cases dropped out) and a control group (41 cases, 2 cases were eliminated and 2 cases dropped out). The routine treatment, nursing care and rehabilitation training were performed in the control group. On the basis of the intervention as the control group, in the observation group, the turmeric blistering moxibustion plaster was applied to bilateral ashi points, Jianyu (LI 15), Jianliao (TE 14), Binao (LI 14), Shousanli (LI 10) and Hegu (LI 4), once a day, remained for 6 hours each time. This moxibustion therapy was operated 5 times weekly, one course of treatment consisted of 2 weeks and 2 courses were required. Separately, before treatment and after 2 and 4 weeks of treatment, the score of visual analogue scale (VAS), shoulder ROM and the score of upper limbs in Fugl-Meyer assessment (U-FMA) were observed in the two groups., Results: VAS scores were lower ( P< 0.05), ROM in shoulder flexion, abduction, internal rotation and external rotation was larger ( P <0.05), and U-FMA scores were higher ( P< 0.05) after 2 and 4 weeks of treatment when compared with those before treatment in the two groups. After 4 weeks of treatment, VAS score decreased ( P< 0.05), and ROM in shoulder flexion, abduction, internal rotation, external rotation and U-FMA score increased ( P <0.05) in comparison with those after 2 weeks of treatment in either group. In the observation group, VAS scores were dropped ( P <0.05) after 2 and 4 weeks of treatment respectively, and ROM of shoulder flexion and abduction enlarged after 2 weeks of treatment ( P< 0.05) when compared with those in the control group. After 4 weeks of treatment, ROM in shoulder flexion, abduction, internal rotation and external rotation in the observation group was larger ( P <0.05) and U-FMA score was higher ( P <0.05) than those in the control group., Conclusions: Acupoint application with turmeric blistering moxibustion plaster may effectively reduce the degree of shoulder pain and improve the shoulder range of motion and the upper limb motor function in the patients with post-stroke hemiplegic shoulder pain.

Background: Patients with heart failure (HF) with mildly reduced or preserved ejection fraction in Asia may have different clinical characteristics and outcomes compared with patients from other parts of the world., Objectives: The purpose of this study was to investigate the clinical characteristics, safety, and efficacy of dapagliflozin in patients in Asia vs outside Asia in the DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure) trial., Methods: In the DELIVER trial, patients with HF and left ventricular ejection fraction >40% were enrolled across 353 sites in 20 countries. The effects of dapagliflozin vs placebo on primary (composite of worsening HF or cardiovascular death) and secondary outcomes were compared in patients from Asia vs outside Asia., Results: Among 6,263 participants, 1,226 (19.6%) were enrolled in Asia. Participants from Asia were less likely to have diabetes, hypertension, history of myocardial infarction, or obesity. After adjusting for clinically relevant characteristics, those in Asia had similar risks of primary composite outcome compared with those from outside Asia (HR: 0.97; 95% CI: 0.82-1.15). Those in Asia had a lower risk of all-cause mortality compared with those enrolled outside Asia (HR: 0.54; 95% CI: 0.44-0.66). Enrollment from Asia did not modify the effect of dapagliflozin on the primary outcome ( P interaction  = 0.54). Serious adverse events and rates of drug discontinuation were also balanced in both treatment arms, irrespective of enrollment in Asia vs outside Asia., Conclusions: In the global DELIVER trial, dapagliflozin reduced the risk of CV death or worsening HF events and was well tolerated among participants enrolled in both Asia and other geographic regions., Competing Interests: AstraZeneca was the sponsor and funder of the DELIVER trial.

Aim: COVID-19 may affect clinical risk in patients with heart failure. DELIVER began before and was conducted during the COVID-19 pandemic. This study aimed to evaluate the association between COVID-19 and clinical outcomes among DELIVER participants., Methods and Results: Participants with chronic heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF) were randomized to dapagliflozin or placebo across 350 sites in 20 countries. COVID-19 was investigator-reported and the contribution of COVID-19 to death was centrally adjudicated. We assessed (i) the incidence of COVID-19, (ii) event rates before/during the pandemic, and (iii) risks of death after COVID-19 diagnosis compared to risks of death in participants without COVID-19. Further, we performed a sensitivity analysis assessing treatment effects of dapagliflozin vs. placebo censored at pandemic onset. Of 6263 participants, 589 (9.4%) developed COVID-19, of whom 307 (52%) required/prolonged hospitalization. A total of 155 deaths (15% of all deaths) were adjudicated as definitely/possibly COVID-19-related. COVID-19 cases and deaths did not differ by randomized assignment. Death rate in the 12 months following diagnosis was 56.1 (95% confidence interval [CI] 48.0-65.6) versus 6.4 (95% CI 6.0-6.8)/100 participant-years among trial participants with versus without COVID-19 (adjusted hazard ratio [aHR] 8.60, 95% CI 7.18-10.30). Risk was highest 0-3 months following diagnosis (153.5, 95% CI 130.3-180.8) and remained elevated at 3-6 months (12.6, 95% CI 6.6-24.3/100 participant-years). After excluding investigator-reported fatal COVID-19 events, all-cause death rates in the 12 months following diagnosis among COVID-19 survivors (n = 458) remained higher (aHR 2.46, 95% CI 1.83-3.33) than rates for all trial participants from randomization, with censoring of participants who developed COVID-19 at the time of diagnosis. Dapagliflozin reduced cardiovascular death/worsening HF events when censoring participants at COVID-19 diagnosis (HR 0.81, 95% CI 0.72-0.91) and pandemic onset (HR 0.72, 95% CI 0.58-0.89). There were no diabetic ketoacidosis or major hypoglycaemic events within 30 days of COVID-19., Conclusion: DELIVER is one of the most extensive experiences with COVID-19 of any cardiovascular trial, with >75% of follow-up time occurring during the pandemic. COVID-19 was common, with >50% of cases leading to hospitalization or death. Treatment benefits of dapagliflozin persisted when censoring at COVID-19 diagnosis and pandemic onset. Patients surviving COVID-19 had a high early residual risk., Clinical Trial Registration: ClinicalTrials.gov Identifier NCT03619213., (© 2023 The Authors.

Background: Cardio-renal-metabolic (CRM) conditions are individually common among patients with heart failure (HF), but the prevalence and influence of overlapping CRM conditions in this population have not been well-studied., Objectives: This study aims to evaluate the impact of overlapping CRM conditions on clinical outcomes and treatment effects of dapagliflozin in HF., Methods: In this post hoc analysis of DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure), we evaluated the prevalence of comorbid CRM conditions (atherosclerotic cardiovascular disease, chronic kidney disease, and type 2 diabetes), their impact on the primary outcome (cardiovascular death or worsening HF), and treatment effects of dapagliflozin by CRM status., Results: Among 6,263 participants, 1,952 (31%), 2,245 (36%), and 1,236 (20%) had 1, 2, and 3 additional CRM conditions, respectively. HF alone was uncommon (13%). Greater CRM multimorbidity was associated with older age, higher body mass index, longer-duration HF, worse health status, and lower left ventricular ejection fraction. Risk of the primary outcome increased with higher CRM overlap, with 3 CRM conditions independently associated with highest risk of primary events (adjusted HR: 2.16 [95% CI: 1.72-2.72]; P < 0.001) compared with HF alone. Relative benefits of dapagliflozin on the primary outcome were consistent irrespective of the type of CRM overlap (P interaction  = 0.773) and by the number of CRM conditions (P interaction  = 0.734), with greatest absolute benefits among those with highest CRM multimorbidity. Estimated 2-year numbers needed to treat with dapagliflozin to prevent 1 primary event were approximately 52, 39, 33, and 24 for participants with 0, 1, 2, and 3 additional CRM conditions at baseline, respectively. Adverse events between treatment arms were similar across the CRM spectrum., Conclusions: CRM multimorbidity was common and associated with adverse outcomes among patients with HF and left ventricular ejection fraction >40% in DELIVER. Dapagliflozin was safe and effective across the CRM spectrum, with greater absolute benefits among those with highest CRM overlap (Dapagliflozin Evaluation to Improve the LIVEs of Patients With Preserved Ejection Fraction Heart Failure [DELIVER]; NCT03619213)., Competing Interests: Funding Support and Author Disclosures DELIVER was sponsored by AstraZeneca.

Background: Patients with heart failure (HF) have a high burden of multimorbidity, often necessitating numerous medications. There may be clinical concern about introducing another medication, especially among individuals with polypharmacy., Objectives: This study examined the efficacy and safety of addition of dapagliflozin according to the number of concomitant medications in HF with mildly reduced or preserved ejection fraction., Methods: In this post hoc analysis of the DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trial, 6,263 participants with symptomatic HF with left ventricular ejection fraction >40% were randomized to dapagliflozin or placebo. Baseline medication use (including vitamins and supplements) was collected. Efficacy and safety outcomes were assessed by medication use categories ("nonpolypharmacy": <5 medications; "polypharmacy": 5 to 9 medications; and "hyperpolypharmacy": ≥10 medications) and continuously. The primary outcome was worsening HF or cardiovascular death., Results: Overall, 3,795 (60.6%) patients met polypharmacy and 1,886 (30.1%) met hyperpolypharmacy criteria. Higher numbers of medications were strongly associated with higher comorbidity burden and increased rates of the primary outcome. Compared with placebo, dapagliflozin similarly reduced the risk of the primary outcome irrespective of polypharmacy status (nonpolypharmacy HR: 0.88 [95% CI: 0.58-1.34]; polypharmacy HR: 0.88 [95% CI: 0.75-1.03]; hyperpolypharmacy HR: 0.73 [95% CI: 0.60-0.88]; P interaction  = 0.30). Similarly, benefits with dapagliflozin were consistent across the spectrum of total medication use (P interaction  = 0.06). Although adverse events increased with higher number of medications, they were not more frequent with dapagliflozin, regardless of polypharmacy status., Conclusions: In the DELIVER trial, dapagliflozin safely reduced worsening HF or cardiovascular death across a broad range of baseline medication use, including among individuals with polypharmacy (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure [DELIVER]; NCT03619213)., Competing Interests: Funding support and author disclosures The DELIVER trial was funded by AstraZeneca.

Background: With the progress of therapeutic drug monitoring (TDM) technology and the development of evidence-based medicine, many guidelines were developed and implemented in recent decades., Objective: The aim was to evaluate the current status of TDM guidelines and provide suggestions for their development and updates based on Appraisal of Guidelines for Research and Evaluation (AGREE) II., Methods: The TDM guidelines were systematically searched for among databases including PubMed, Embase, China National Knowledge Infrastructure, Wanfang Data, and the Chinese biomedical literature service system and the official websites of TDM-related associations. The search period was from inception to 6 April 2023. Four researchers independently screened the literature and extracted data. Any disagreement was discussed and reconciled by another researcher. The quality of guidelines was assessed using the AGREE II instrument., Results: A total of 92 guidelines were included, including 57 technical guidelines, three management guidelines, and 32 comprehensive guidelines. The number of TDM guidelines has gradually increased since 1979. The United States published the most guidelines (20 guidelines), followed by China (15 guidelines) and the United Kingdom (ten guidelines), and 23 guidelines were developed by international organizations. Most guidelines are aimed at adult patients only, while 28 guidelines include special populations. With respect to formulation methods, there are 23 evidence-based guidelines. As for quality evaluation results based on AGREE II, comprehensive guidelines scored higher (58.16%) than technical guidelines (51.36%) and administrative guidelines (50.00%)., Conclusion: The number of TDM guidelines, especially technical and comprehensive ones, has significantly increased in recent years. Most guidelines are confronted with the problems of unclear methodology and low quality of evidence according to AGREE II. More evidence-based research on TDM and high-quality guideline development is recommended to promote individualized therapy., (© 2023.

Aims: The Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure (DELIVER) trial demonstrated the sodium-glucose cotransporter 2 inhibitor dapagliflozin to be beneficial in patients with symptomatic heart failure (HF) with improved ejection fraction (HFimpEF; those with prior left ventricular ejection fraction ≤40% that had improved to >40% by enrolment). Whether this benefit differs by background medical therapy is unclear. The current study aims to determine the efficacy and safety of dapagliflozin among patients with HFimpEF by background medical therapy., Methods and Results: Treatment effects on the primary endpoint (worsening HF or cardiovascular death) were assessed by number of background HF medical therapies (angiotensin-converting enzyme inhibitor/angiotensin receptor blocker/angiotensin receptor-neprilysin inhibitor, evidence-based beta-blocker, and mineralocorticoid receptor antagonist). Among the 6263 patients randomized in DELIVER, 1151 (18%) had HFimpEF. Of those, 21% of patients were on 0-1 therapies, 44% were on two therapies, and 35% were on three therapies. During 2.3 years of median follow-up, the incidence rate of the primary outcome was 9.7, 8.8, and 8.4 per 100 person-years for patients on 0-1, 2 and 3 HF medications at baseline, respectively. Treatment effects with dapagliflozin on the primary outcome may be greater in patients with HFimpEF on 0-1 therapies at baseline (p interaction  = 0.09), driven mostly by a significant interaction for HF hospitalization (p interaction  = 0.023) with no evidence of effect modification for cardiovascular death (p interaction  = 0.65). Treatment effects of dapagliflozin on the primary outcome were, however, consistent when assessed across the modified Heart Failure Collaboratory Medical Therapy Score integrating both therapeutic use and dosing (p interaction  = 0.39). The use of dapagliflozin was not associated with changes in use or doses of background HF therapies, and among patients on three HF medications at baseline, the addition of dapagliflozin did not lead to higher adverse events., Conclusions: In patients with HFimpEF, the safety and efficacy of dapagliflozin were largely similar by background use and dosing of HF medical therapies. The benefit of dapagliflozin in reducing HF events tended to be greater in those patients on 0-1 medications at baseline. Among patients already on three HF medical therapies, the addition of dapagliflozin was safe without requiring de-escalation of other therapies., (© 2023 The Authors.

Background: Aortic dissection (AD) is a fatal cardiovascular disorder without effective medications due to unclear pathogenic mechanisms. Bestrophin3 (Best3), the predominant isoform of bestrophin family in vessels, has emerged as critical for vascular pathological processes. However, the contribution of Best3 to vascular diseases remains elusive., Methods: Smooth muscle cell-specific and endothelial cell-specific Best3 knockout mice (Best3 SMKO and Best3 ECKO , respectively) were engineered to investigate the role of Best3 in vascular pathophysiology. Functional studies, single-cell RNA sequencing, proteomics analysis, and coimmunoprecipitation coupled with mass spectrometry were performed to evaluate the function of Best3 in vessels., Results: Best3 expression in aortas of human AD samples and mouse AD models was decreased. Best3 SMKO but not Best3 ECKO mice spontaneously developed AD with age, and the incidence reached 48% at 72 weeks of age. Reanalysis of single-cell transcriptome data revealed that reduction of fibromyocytes, a fibroblast-like smooth muscle cell cluster, was a typical feature of human ascending AD and aneurysm. Consistently, Best3 deficiency in smooth muscle cells decreased the number of fibromyocytes. Mechanistically, Best3 interacted with both MEKK2 and MEKK3, and this interaction inhibited phosphorylation of MEKK2 at serine153 and MEKK3 at serine61. Best3 deficiency induced phosphorylation-dependent inhibition of ubiquitination and protein turnover of MEKK2/3, thereby activating the downstream mitogen-activated protein kinase signaling cascade. Furthermore, restoration of Best3 or inhibition of MEKK2/3 prevented AD progression in angiotensin II-infused Best3 SMKO and ApoE -/- mice., Conclusions: These findings unveil a critical role of Best3 in regulating smooth muscle cell phenotypic switch and aortic structural integrity through controlling MEKK2/3 degradation. Best3-MEKK2/3 signaling represents a novel therapeutic target for AD., Competing Interests: Disclosures None.

Aims: Dapagliflozin reduced the combined risk of worsening heart failure or cardiovascular death among patients with heart failure with mildly reduced or preserved ejection fraction. In this study, the safety and efficacy of dapagliflozin according to background diuretic therapy and the influence of dapagliflozin on longitudinal diuretic use were evaluated., Methods and Results: In this pre-specified analysis of the Dapagliflozin Evaluation to Improve the LIVEs of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial, the effects of dapagliflozin vs. placebo were assessed in the following subgroups: no diuretic, non-loop diuretic, and loop diuretic furosemide equivalent doses of <40, 40, and >40 mg, respectively. Of the 6263 randomized patients, 683 (10.9%) were on no diuretic, 769 (12.3%) were on a non-loop diuretic, and 4811 (76.8%) were on a loop diuretic at baseline. Treatment benefits of dapagliflozin on the primary composite outcome were consistent by diuretic use categories (Pinteraction = 0.64) or loop diuretic dose (Pinteraction = 0.57). Serious adverse events were similar between dapagliflozin and placebo arms, irrespective of diuretic use or dosing. Dapagliflozin reduced new initiation of loop diuretics by 32% [hazard ratio (HR) 0.68; 95% confidence interval (CI): 0.55-0.84, P < 0.001] but did not influence discontinuations/disruptions (HR 0.98; 95% CI: 0.86-1.13, P = 0.83) in follow-up. First sustained loop diuretic dose increases were less frequent, and sustained dose decreases were more frequent in patients treated with dapagliflozin: net difference of -6.5% (95% CI: -9.4 to -3.6; P < 0.001). The mean dose of loop diuretic increased over time in the placebo arm, a longitudinal increase that was significantly attenuated with treatment with dapagliflozin (placebo-corrected treatment effect of -2.5 mg/year; 95% CI: -1.5, -3.7, P < 0.001)., Conclusion: In patients with heart failure with mildly reduced or preserved ejection fraction, the clinical benefits of dapagliflozin relative to placebo were consistent across a wide range of diuretic categories and doses with a similar safety profile. Treatment with dapagliflozin significantly reduced new loop diuretic requirement over time., Competing Interests: Conflict of interest: S.C is supported by the Canadian Arthur J.E.

Aims: The PARAGLIDE-HF trial demonstrated reductions in natriuretic peptides with sacubitril/valsartan compared with valsartan in patients with heart failure (HF) with mildly reduced or preserved ejection fraction who had a recent worsening HF event, but was not adequately powered to examine clinical outcomes. PARAGON-HF included a subset of PARAGLIDE-HF-like patients who were recently hospitalized for HF. Participant-level data from PARAGLIDE-HF and PARAGON-HF were pooled to better estimate the efficacy and safety of sacubitril/valsartan in reducing cardiovascular and renal events in HF with mildly reduced or preserved ejection fraction., Methods and Results: Both PARAGLIDE-HF and PARAGON-HF were multicentre, double-blind, randomized, active-controlled trials of sacubitril/valsartan vs. valsartan in patients with HF with mildly reduced or preserved left ventricular ejection fraction (LVEF >40% in PARAGLIDE-HF and ≥45% in PARAGON-HF). In the pre-specified primary analysis, we pooled participants in PARAGLIDE-HF (all of whom were enrolled during or within 30 days of a worsening HF event) with a 'PARAGLIDE-like' subset of PARAGON-HF (those hospitalized for HF within 30 days). We also pooled the entire PARAGLIDE-HF and PARAGON-HF populations for a broader context. The primary endpoint for this analysis was the composite of total worsening HF events (including first and recurrent HF hospitalizations and urgent visits) and cardiovascular death. The secondary endpoint was the pre-specified renal composite endpoint for both studies (≥50% decline in estimated glomerular filtration rate from baseline, end-stage renal disease, or renal death). Compared with valsartan, sacubitril/valsartan significantly reduced total worsening HF events and cardiovascular death in both the primary pooled analysis of participants with recent worsening HF [n = 1088; rate ratio (RR) 0.78; 95% confidence interval (CI) 0.61-0.99; P = 0.042] and in the pooled analysis of all participants (n = 5262; RR 0.86; 95% CI: 0.75-0.98; P = 0.027). In the pooled analysis of all participants, first nominal statistical significance was reached by Day 9 after randomization, and treatment benefits were larger in those with LVEF ≤60% (RR 0.78; 95% CI 0.66-0.91) compared with those with LVEF >60% (RR 1.09; 95% CI 0.86-1.40; Pinteraction = 0.021). Sacubitril/valsartan was also associated with lower rates of the renal composite endpoint in the primary pooled analysis [hazard ratio (HR) 0.67; 95% CI 0.43-1.05; P = 0.080] and the pooled analysis of all participants (HR 0.60; 95% CI 0.44-0.83; P = 0.002)., Conclusion: In pooled analyses of PARAGLIDE-HF and PARAGON-HF, sacubitril/valsartan reduced cardiovascular and renal events among patients with HF with mildly reduced or preserved ejection fraction. These data provide support for use of sacubitril/valsartan in patients with HF with mildly reduced or preserved ejection fraction, particularly among those with an LVEF below normal, regardless of care setting., (© The Author(s) 2023.

Aims: Dapagliflozin resulted in significant and sustained reductions in first and recurrent heart failure (HF) hospitalizations among patients with HF across the spectrum of ejection fraction. How treatment with dapagliflozin differentially impacts hospitalization for HF of varying complexity is not well studied., Methods and Results: In the DELIVER and DAPA-HF trials, we examined the effects of dapagliflozin on adjudicated HF hospitalizations of varying complexity and hospital length of stay (LOS). HF hospitalizations requiring intensive care unit stay, intravenous vasoactive therapies, invasive/non-invasive ventilation, mechanical fluid removal or mechanical circulatory support were categorized as complicated. The balance was classified as uncomplicated. Of the total 1209 HF hospitalizations reported in DELIVER, 854 (71%) were uncomplicated and 355 (29%) were complicated. Of the total 799 HF hospitalizations reported in DAPA-HF, 453 (57%) were uncomplicated and 346 (43%) were complicated. Relative to patients experiencing a first uncomplicated HF hospitalization, those with complicated HF hospitalizations had a significantly higher in-hospital mortality both in DELIVER (16.7% vs. 2.3%, p < 0.001) and DAPA-HF (15.1% vs. 3.8%, p < 0.001). Dapagliflozin similarly reduced total 'uncomplicated' (DELIVER: rate ratio [RR] 0.67, 95% confidence interval [CI] 0.55-0.82 and DAPA-HF: RR 0.69, 95% CI 0.54-0.87) and 'complicated' HF hospitalizations (DELIVER: RR 0.82, 95% CI 0.63-1.06 and DAPA-HF: RR 0.75, 95% CI 0.58-0.97). Dapagliflozin consistently reduced hospitalizations irrespective of their LOS: <5 days (DELIVER: RR 0.76, 95% CI 0.58-0.99 and DAPA-HF: RR 0.58, 95% CI 0.42-0.80) or ≥5 days (DELIVER: RR 0.71, 95% CI 0.58-0.86 and DAPA-HF: RR 0.77, 95% CI 0.62-0.94)., Conclusion: A substantial proportion of hospitalizations (∼30-40%) among patients with HF irrespective of ejection fraction required intensification of treatment beyond standard intravenous diuretics. Such patients experienced significantly higher in-hospital mortality. Treatment with dapagliflozin consistently reduced HF hospitalizations regardless of severity of inpatient course or LOS., Clinical Trial Registration: ClinicalTrials.gov, DELIVER (NCT03619213) and DAPA-HF (NCT03036124)., (© 2023 The Authors.

Aim: The globalization of clinical trials has highlighted geographic differences in patient characteristics, treatments, and outcomes. We examined these differences in PARADISE-MI., Methods and Results: Overall, 23.0% were randomized in Eastern Europe/Russia, 17.5% in Western Europe, 12.2% in Southern Europe, 10.1% in Northern Europe, 12.0% in Latin America (LA), 9.3% in North America (NA), 10.0% in East/South-East Asia and 5.8% in South Asia (SA). Those from Asia, particularly SA, were different from patients enrolled in the other regions, being younger and thinner. They also differed in terms of comorbidities (high prevalence of diabetes and low prevalence of atrial fibrillation), type of myocardial infarction (more often ST-elevation myocardial infarction), and treatment (low rate of primary percutaneous coronary intervention). By contrast, patients from LA did not differ meaningfully from those randomized in Europe or NA. Use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (34.8%) and beta-blockers (65.5%) was low in SA, whereas mineralocorticoid receptor antagonist use was lowest in NA (22%) and highest in Eastern Europe/Russia (53%). Rates of the primary composite outcome of cardiovascular death or incident heart failure varied two-fold among regions, with the lowest rate in SA (4.6/100 person-years) and the highest in LA (9.2/100 person-years). Rates of incident heart failure varied almost six-fold among regions, with the lowest rate in SA (1.0/100 person-years) and the highest in Northern Europe (5.9/100 person-years). The effect of sacubitril/valsartan was not modified by region., Conclusion: In PARADISE-MI, there were substantial regional differences in patient characteristics, treatments and outcomes. Although the generalizability of these findings to a 'real-world' unselected population may be limited, these findings underscore the importance of considering both regional and within-region differences when designing global clinical trials., (© 2023 European Society of Cardiology.)

Aims: Patients with heart failure experience a high burden of symptoms and physical limitations, and poor quality of life. Dapagliflozin reduces heart failure hospitalization and cardiovascular death in patients with reduced, mildly reduced, and preserved ejection fractions. We examined the effects of dapagliflozin on health status, measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ), across the full spectrum of left ventricular ejection fraction (LVEF)., Methods and Results: Participant-level data were pooled from the DAPA-HF and DELIVER trials. Both trials were randomized, global, double-blind, placebo-controlled trials of patients with symptomatic heart failure and elevated natriuretic peptides. DAPA-HF and DELIVER included patients with LVEF ≤40% and LVEF >40%, respectively. KCCQ was evaluated at randomization and at 4 and 8 months post-randomization; the effect of dapagliflozin versus placebo on KCCQ total symptom score (TSS) was a pre-specified secondary outcome in both trials. Interaction testing was performed to assess potential heterogeneity in the effects of dapagliflozin versus placebo on KCCQ-TSS, clinical summary score (CSS), overall summary score (OSS), and physical limitation score (PLS), by continuous LVEF using restricted cubic splines. Responder analyses examining the proportion of patients with meaningful deterioration (≥5 point decline) and meaningful improvements (≥5 point increase) in KCCQ-TSS was assessed across LVEF categories. Of 11 007 randomized participants, 10 238 (93%) had full data on KCCQ-TSS at randomization. Benefits of dapagliflozin versus placebo on KCCQ-TSS, -CSS, -OSS, -PLS, at 8 months were consistent across the full range of LVEF (p interaction  = 0.19, 0.10, 0.12, 0.10, respectively). In responder analyses, fewer dapagliflozin- versus placebo-treated patients had clinically meaningful deteriorations in KCCQ-TSS (overall: 21% vs. 23%; LVEF ≤40%: 21% vs. 29%; LVEF 41-60%: 21% vs. 26%; LVEF >60%: 22% vs. 27%). A greater proportion of patients randomized to dapagliflozin experienced at least small improvements in KCCQ-TSS (overall: 50% vs. 45%; LVEF ≤40%: 48% vs. 41%; LVEF 41-60%: 51% vs. 49%; LVEF >60%: 53% vs. 45%). The effects of dapagliflozin versus placebo on clinically meaningful deteriorations and improvements in health status by KCCQ-TSS were consistent across the full spectrum of LVEF assessed continuously (p interaction  = 0.20 and 0.64, respectively). Across the LVEF spectrum, the number needed to treat to affect ≥5 point improvement in health status assessed by KCCQ-TSS was 20. Health status declines preceding a HF hospitalization by ∼10 points were observed in both trials, evident up to 3 months prior to hospitalization., Conclusions: In participant-level pooled analyses of DAPA-HF and DELIVER, dapagliflozin improved all key domains of health status across the full range of LVEF. Clinically meaningful improvements in health status were also observed consistently across LVEF, including in those with LVEF >60%., Clinical Trial Registration: NCT03036124 and NCT03619213., (© 2023 The Authors.

Background: Sintilimab combined with IBI305 treatment regimen had potential clinical benefits than sorafenib in the first-line treatment of patients with unresectable hepatic cell carcinoma (HCC). However, whether sintilimab plus IBI305 has economic benefits in China remains unclear., Methods: From the perspective of Chinese payers, we used the Markov model to simulate patients with HCC receiving treatment with sintilimab plus IBI305 and sorafenib. The transition probability between health states was estimated using the parametric survival model, and the cumulative medical costs and utility of the two treatment methods were estimated. Considering the incremental cost-effectiveness ratios (ICERs) as the evaluation index, sensitivity analyses were performed to explore the impact of uncertainty on the results., Results: Compared to sorafenib, sintilimab plus IBI305 generated an additional $17552.17 and 0.33 quality-adjusted life years, resulting in an ICER of $52817.89. The analysis outcomes were most sensitive to the total cost of sintilimab plus IBI305. With a willingness-to-pay threshold of $38,334, sintilimab plus IBI305 showed a 1.28% probability of being cost-effective. The total cost of sintilimab plus IBI305 should be reduced by at least 31.9% to be accepted by Chinese payers., Conclusions: Regardless of whether the price of sintilimab plus IBI305 and sorafenib is covered by Medicare, sintilimab plus IBI305 is unlikely to be cost-effective for first-line treatment of patients with unresectable HCC., (© 2023 The Authors.

Osteoarthritis (OA)-the most prevalent of arthritis diseases-is a complicated pathogenesis caused by cartilage degeneration and synovial inflammation. Suramin has been reported to enhance chondrogenic differentiation. However, the therapeutic effect of suramin on OA-induced cartilage destruction has remained unclear. Suramin is an anti-parasitic drug that has potent anti-purinergic properties. This study investigated the protective effects and underlying mechanisms of suramin on articular cartilage degradation using an in vitro study and mice model with post-traumatic OA. We found that suramin markedly suppressed the IL-1β increased expression of matrix destruction proteases-such as ADAMT4, ADAMTS5, MMP3, MMP13, and inflammatory mediators-including the iNOS, COX2, TNFα, and IL-1β; while greatly enhancing the synthesis of cartilage anabolic factors-such as COL2A1, Aggrecan and SOX9 in IL-1β-induced porcine chondrocytes. In vivo experiments showed that intra-articular injection of suramin ameliorated cartilage degeneration and inhibited synovial inflammation in an anterior cruciate ligament transection (ACLT)-induced OA mouse model. In mechanistic studies, we found that exogenous supplementation of suramin can activate Nrf2, and accordingly inhibit the nuclear factor kappa-light-chain-enhancer of activated B cells (NF- κB) and mitogen-activated protein kinase (MAPK) pathways, thereby alleviating the inflammation and ECM degeneration of chondrocytes stimulated by IL-1β. In addition, suramin also repolarized M1 macrophages to the M2 phenotype, further reducing the apoptosis of chondrocytes. Collectively, the results of the study suggests that suramin is a potential drugs which could serve as a facilitating drug for the application of OA therapy toward clinical treatment., 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 © 2023 Elsevier B.V.

Aims: Patients recently hospitalized for heart failure (HF) often have unstable haemodynamics and experience worsening renal failure, and are at elevated risk for recurrent HF events. In DELIVER, dapagliflozin reduced HF events or cardiovascular death including among patients who were hospitalized or recently hospitalized., Methods and Results: We examined the effects of dapagliflozin versus placebo on estimated glomerular filtration rate (eGFR) slope (acute and chronic), 1-month change in systolic blood pressure, and the occurrence of serious hypovolaemic or renal adverse events in patients with and without HF hospitalization within 30 days of randomization. The 654 (90 randomized during hospitalization, 147 1-7 days post-discharge and 417 8-30 days post-discharge) recently hospitalized patients had lower baseline eGFR compared with those without recent HF hospitalization (median [interquartile range] 55 [43, 71] vs. 60 [47, 75] ml/min/1.73 m 2 ). Dapagliflozin consistently reduced the risk of all-cause (p interaction  = 0.20), cardiac-related (p interaction  = 0.75), and HF-specific (p interaction  = 0.90) hospitalizations, irrespective of recent HF hospitalization. In those recently hospitalized, acute placebo-corrected eGFR reductions with dapagliflozin were modest and similar to patients without recent hospitalization (-2.0 [-4.1, +0.1] vs. -3.4 [-3.9, -2.9] ml/min/1.73 m 2 , p interaction  = 0.12). Dapagliflozin's effect to slow chronic eGFR decline was similar regardless of recent hospitalization (p interaction  = 0.57). Dapagliflozin had a minimal effect on 1-month systolic blood pressure and to a similar degree in patients with and without recent hospitalization (-1.3 vs.-1.8 mmHg, p interaction  = 0.64). There was no treatment-related excess in renal or hypovolaemic serious adverse events, irrespective of recent HF hospitalization., Conclusion: In patients recently hospitalized with HF, initiation of dapagliflozin had minimal effects on blood pressure and did not increase renal or hypovolaemic serious adverse events, yet afforded long-term cardiovascular and kidney protective effects. These data suggest that the benefit to risk ratio favours initiation of dapagliflozin among stabilized patients hospitalized or recently hospitalized for HF., Clinical Trial Registration: ClinicalTrials.gov NCT03619213., (© 2023 The Authors.

Objective: This meta-analysis was designed to investigate the associations between  SLCO1B1 , APOE  and CYP2C9  and the lipid-lowering effects and pharmacokinetics of fluvastatin. Methods: Studies were searched from inception to March 2023, including three SNPs related to fluvastatin, SLCO1B1 , CYP2C9 and  APOE . Weighted mean differences and corresponding 95% CIs were analyzed to evaluate the associations between SNPs and outcomes. Results: SLCO1B1 521T>C was associated with lower total cholesterol and low-density lipoprotein reduction. Patients carrying 521CC or total cholesterol had a significantly higher area under the curve than those carrying 521TT, but no significant difference existed. Conclusion: CYP2C9 and SLCO1B1 may be associated with the efficacy and pharmacokinetics of fluvastatin.

Background: In April 2009, the Chinese government launched Zero Markup Drug Policy (ZMDP) to adjust medical institutions' revenue and expenditure structures., Objective: This study evaluated the impact of implementing ZMDP (as an intervention) on the drug costs for managing Parkinson's disease (PD) and its complications from the healthcare providers' perspective., Methods: The drug costs for managing PD and its complications per outpatient visit or inpatient stay were estimated using electronic health data from a tertiary hospital in China from January 2016 to August 2018. An interrupted time series analysis was conducted to evaluate the immediate change following the intervention (step change, β 1 ) and the change in slope, comparing post-intervention with the pre-intervention period (trend change, β 2 ). Subgroup analyses were conducted in outpatients within the strata of age, patients with or without health insurance, and whether drugs were listed in the national Essential Medicine List (EML)., Results: Overall, 18,158 outpatient visits and 366 inpatient stays were included. Outpatient (β 1 = -201.7, 95%CI: -285.4, -117.9) and inpatient (β 1 = -372.1, 95% CI: -643.6, -100.6) drug costs for managing PD significantly decreased when implementing ZMDP. However, for outpatients without health insurance, the trend change in drug costs for managing PD (β 2 = 16.8, 95% CI: 8.0, 25.6) or PD complications (β 2 = 12.6, 95% CI: 5.5, 19.7) significantly increased. Trend changes in outpatient drug costs for managing PD differed when stratifying drugs listed in EML (β 2 = -1.4, 95% CI: -2.6, -0.2) or not (β 2 = 6.3, 95%CI: 2.0, 10.7). Trend changes of outpatient drug costs for managing PD complications significantly increased in drugs listed in EML (β 2 = 14.7, 95% CI 9.2, 20.3), patients without health insurance (β 2 = 12.6, 95% CI 5.5, 19.7), and age under 65 (β 2 = 24.3, 95% CI 17.3, 31.4)., Conclusions: Drug costs for managing PD and its complications significantly decreased when implementing ZMDP. However, the trend in drug costs increased significantly in several subgroups, which may offset the decrease at the implementation., 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., (Copyright © 2023 Wang, Li, Gu, Cai, Wang, Yi and Chen.)

Background: Scalable and safe approaches for heart failure guideline-directed medical therapy (GDMT) optimization are needed., Objectives: The authors assessed the safety and effectiveness of a virtual care team guided strategy on GDMT optimization in hospitalized patients with heart failure with reduced ejection fraction (HFrEF)., Methods: In a multicenter implementation trial, we allocated 252 hospital encounters in patients with left ventricular ejection fraction ≤40% to a virtual care team guided strategy (107 encounters among 83 patients) or usual care (145 encounters among 115 patients) across 3 centers in an integrated health system. In the virtual care team group, clinicians received up to 1 daily GDMT optimization suggestion from a physician-pharmacist team. The primary effectiveness outcome was in-hospital change in GDMT optimization score (+2 initiations, +1 dose up-titrations, -1 dose down-titrations, -2 discontinuations summed across classes). In-hospital safety outcomes were adjudicated by an independent clinical events committee., Results: Among 252 encounters, the mean age was 69 ± 14 years, 85 (34%) were women, 35 (14%) were Black, and 43 (17%) were Hispanic. The virtual care team strategy significantly improved GDMT optimization scores vs usual care (adjusted difference: +1.2; 95% CI: 0.7-1.8; P < 0.001). New initiations (44% vs 23%; absolute difference: +21%; P = 0.001) and net intensifications (44% vs 24%; absolute difference: +20%; P = 0.002) during hospitalization were higher in the virtual care team group, translating to a number needed to intervene of 5 encounters. Overall, 23 (21%) in the virtual care team group and 40 (28%) in usual care experienced 1 or more adverse events (P = 0.30). Acute kidney injury, bradycardia, hypotension, hyperkalemia, and hospital length of stay were similar between groups., Conclusions: Among patients hospitalized with HFrEF, a virtual care team guided strategy for GDMT optimization was safe and improved GDMT across multiple hospitals in an integrated health system. Virtual teams represent a centralized and scalable approach to optimize GDMT., Competing Interests: Funding Support and Author Disclosures Funding was provided by the Brigham Health Care Redesign Incubator and Startup Program, Brigham and Women’s Hospital, Mass General Brigham, Boston, Massachusetts.

Background: Omecamtiv mecarbil improves cardiovascular outcomes in patients with heart failure (HF) with reduced ejection fraction (EF). Consistency of drug benefit across race is a key public health topic., Objectives: The purpose of this study was to evaluate the effect of omecamtiv mecarbil among self-identified Black patients., Methods: In GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) patients with symptomatic HF, elevated natriuretic peptides, and left ventricular ejection fraction (LVEF) ≤35% were randomized to omecamtiv mecarbil or placebo. The primary outcome was a composite of time to first event of HF or cardiovascular death. The authors analyzed treatment effects in Black vs White patients in countries contributing at least 10 Black participants., Results: Black patients accounted for 6.8% (n = 562) of overall enrollment and 29% of U.S. enrollment. Most Black patients enrolled in the United States, South Africa, and Brazil (n = 535, 95%). Compared with White patients enrolled from these countries (n = 1,129), Black patients differed in demographics, comorbid conditions, received higher rates of medical therapy and lower rates of device therapies, and experienced higher overall event rates. The effect of omecamtiv mecarbil was consistent in Black vs White patients, with no difference in the primary endpoint (HR = 0.83 vs 0.88, P-interaction = 0.66), similar improvements in heart rate and N-terminal pro-B-type natriuretic peptide, and no significant safety signals. Among endpoints, the only nominally significant treatment-by-race interaction was the placebo-corrected change in blood pressure from baseline in Black vs White patients (+3.4 vs -0.7 mm Hg, P for interaction = 0.02)., Conclusions: GALACTIC-HF enrolled more Black patients than other recent HF trials. Black patients treated with omecamtiv mecarbil had similar benefit and safety compared with White counterparts., Competing Interests: Funding Support and Author Disclosures The GALACTIC-HF trial was funded by Amgen (Thousand Oaks, California, USA), Cytokinetics, Inc (South San Francisco, California, USA), and Servier Laboratories (Suresnes, France).

Primary liver cancer is the sixth most commonly diagnosed cancer and was the third leading cause of cancer deaths worldwide in 2020. It includes hepatocellular carcinoma (HCC) (representing 75%-85% of cases), intrahepatic cholangiocarcinoma (representing 10%-15% of cases), and other rare types. The survival rate of patients with HCC has risen with improved surgical technology and perioperative management in recent years; however, high tumor recurrence rates continue to limit long-term survival, even after radical surgical resection (exceeding 50% recurrence). For resectable recurrent liver cancer, surgical removal [either salvage liver transplantation (SLT) or repeat hepatic resection] remains the most effective therapy that is potentially curative for recurrent HCC. Thus, here, we introduce surgical treatment for recurrent HCC. Areas Covered: A literature search was performed for recurrent HCC using Medline and PubMed up to August 2022. Expert commentary: In general, long-term survival after the re-resection of recurrent liver cancer is usually beneficial. SLT has equivalent outcomes to primary liver transplantation for unresectable recurrent illness in a selected group of patients; however, SLT is constrained by the supply of liver grafts. SLT seems to be inferior to repeat liver resection when considering operative and postoperative results but has the major advantage of disease-free survival. When considering the similar overall survival rate and the current situation of donor shortages, repeat liver resection remains an important option for recurrent HCC., Competing Interests: Conflict-of-interest statement: The authors report no conflicts of interest in this work., (©The Author(s) 2023.

Two-dimensional (2D) materials have potential application and wide development prospects in photoelectron and spintronic devices. However, the properties of different growth conditions are challenging to study in the future. This, in turn, hinders further research into 2D materials and the manufacture of high-quality devices. A comprehensive understanding of the ultrafast laser spectroscopy and dynamics that take into account the substrate-transition metal dichalcogenide (TMD) interaction is lacking. Here, the strain effect is elucidated by systematically investigating the interfacial interaction between different substrates and MoS 2 . The strain and interface engineering of MoS 2 /seeds layer heterointerface and light-matter coupling are discussed in the Raman and photoluminescence spectra. The dramatic enhanced PL originates from the phase transition of MoS 2 on different substrates and electron-hole pairs dissociated by exciton screening effect. Finite-difference time-domain simulation confirmed that the electric field, magnetic field, and polarization field of the heterojunction system changed after the strain was applied. In addition, based on the dependence of physical parameters of MoS 2 , the relative numerical changes of physical parameters of MoS 2 films on different substrates as well as the photoelectric transfer, strain, and charge doping levels on the surface or interface will provide a direction for optimizing the selection of various devices.

Aims: Radiation by-radiation effect (RIBE) can induce the genomic instability of bone marrow mesenchymal stem cells (BMSCs) adjacent to lung cancer, and this effect not only exists in the short-term, but also accompanies it in the long-term, but its specific mechanism is not clear. Our goal is to explore the similarities and differences in the mechanism of genomic damage in tumor-associated BMSCs induced by short-term and long-term RIBE, and to provide a theoretical basis for adjuvant drugs for protection against RIBE at different clinical time periods. Results: We found that both short- and long-term RIBE induced genomic instability. We could show a high expression of TGF-β1, TNF-α, and HIF-1α in tumor-associated BMSCs after short-term RIBE whereas only TNF-α and HIF-1α expression was increased in long-term RIBE. We further confirmed that genomic instability is associated with the activation of the HIF-1α pathway and that this is mediated by TNF-α and TGF-β1. In addition, we found differences in the mechanisms of genomic instability in the considered RIBE windows of analysis. In short-term RIBE, both TNF-α and TGF-β1 play a role, whereas only TNF-α plays a decisive role in long-term RIBE. In addition, there were differences in BMSC recruitment and genomic instability of different tissues with a more pronounced expression in tumor and bone marrow than compared to lung. Innovation and Conclusion: We could show dynamic changes in the expression of the cytokines TGF-β1 and TNF-α during short- and long-term RIBE. The differential expression of the two is the key to causing the genomic damage of tumor-associated BMSCs in the considered windows of analysis. Therefore, these results may serve as a guideline for the administration of radiation protection adjuvant drugs at different clinical stages. Antioxid. Redox Signal. 38, 747-767.

Aims: Infections are common complications after stroke and associated with unfavourable outcomes. We aimed to evaluate the efficacy and safety of prophylactic antibiotics for post-acute stroke infection., Methods: We searched PubMed, Embase, the Cochrane Library, SinoMed, China National Knowledge Infrastructure, WanFang Data, China Science and Technology Journal Database, and clinical trial register platforms from inception to 15 February 2022. We included randomized clinical trials that evaluated the efficacy and safety of prophylactic antibiotics. Primary outcomes were mortality rate and incidence of pneumonia. The pooled risk ratio (RR) and mean differences with 95% confidence interval (CI) were calculated using the random or fixed-effect model depending on heterogeneity. The quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluations., Results: Twelve studies (4809 participants) were included. There was no significant difference in the mortality rate (12 trials, n = 4740, RR 1.03 [95% Cl: 0.91-1.16], high-quality evidence), incidence of pneumonia (7 trials, n = 4352, RR 0.94 [95% CI: 0.79-1.11], high-quality evidence) and the incidence of adverse events between the prophylactic antibiotics and control groups. Prophylactic antibiotics significantly reduced the incidence of infections (8 trials, n = 4517, RR 0.72 [95% CI: 0.58-0.89], moderate-quality evidence) and urinary tract infections (7 trials, n = 4352, RR 0.39 [95% CI: 0.3-0.49], moderate-quality evidence). None of the subgroup analyses showed a significant difference in mortality or the incidence of pneumonia., Conclusion: For acute stroke patients, prophylactic antibiotics were significantly associated with fewer incidences of any infections and urinary tract infections without significant differences in mortality rate and pneumonia., (© 2022 British Pharmacological Society.)

Objective: The KEYNOTE-590 trial showed that individuals with advanced esophageal cancer who received Pembrolizumab in combination with chemotherapy as a first-line regimen achieved a significant extension of survival. However, this treatment option increases the financial burden on patients and the economic benefits remain to be further evaluated., Methods: A Markov model was used to simulate 10-year survival of patients with esophageal cancer from the perspective of United States (US) Medicare payers. We evaluated the economics of Pembrolizumab plus chemotherapy in the PD-L1 positive score (CPS ≥10) and any PD-L1 expression groups, respectively. We estimated total costs, quality-adjusted life years (QALYs), and calculated incremental cost effectiveness ratios (ICERs). Sensitivity analyses were conducted to explore the impact of uncertainties on the results. Subgroup analysis was also performed., Results: The analysis results showed that the ICER for pembrolizumab plus chemotherapy versus chemotherapy alone was $293,513.17/QALYs in the any PD-L1 expression group. This exceeded the threshold of willingness to pay ($150,000/QALYs). ICERs were most sensitive to the cost of pembrolizumab and the ICERs exceeded $150,000/QALYs in all subgroups., Conclusions: Evidence suggests that first-line pembrolizumab in combination with chemotherapy is not a cost-effective option for advanced esophageal cancer in the US, regardless of PD-L1 expression status., (© 2022 The Authors.
