Refractory thyroid cancer is frequently associated with a poor prognosis,necessitating alternative therapeutic approaches.Tyrosine kinase inhibitors(TKIs)have emerged as a promising treatment option,showing generally favorable clinical outcomes in these challenging cancer subtypes.However,the existing body of research is constrained by small sample sizes and variable findings,limiting the ability to directly compare the efficacy of different TKI agents.This study aimed to bridge that gap through a network meta-analysis,evaluating the relative efficacy and safety of various TKIs in managing refractory thyroid cancer.Utilizing systematic keyword searches in databases such as PubMed,Cochrane Library,Embase,Scopus,Web of Science,and ClinicalTrials.gov,we identified studies that met predefined inclusion criteria.Extracted data were analyzed using Bayesian network meta-analysis methods via R software to ensure a comprehensive assessment.Our findings highlighted specific advantages of certain TKIs for various clinical outcomes.In terms of progression-free survival(PFS),Anlotinib and Apatinib showed notable efficacy.For the objective response rate(ORR),Cabozantinib and Lenvatinib demonstrated superior effectiveness,while for disease control rate(DCR),Apatinib and Lenvatinib were advantageous.Regarding safety profiles,Cabozantinib emerged as the safest option for all-grade adverse events(AEs),with Anlotinib showing a higher risk.For severe AEs(grade 3 or higher),Sorafenib proved to be the safest,while Apatinib carried the highest risk.In summary,Anlotinib,Apatinib,Lenvatinib,and Cabozantinib offered significant benefits for PFS,ORR,and DCR in patients with refractory thyroid cancer.However,Anlotinib and Apatinib were associated with higher AE rates,underlining the importance of balancing efficacy with safety.Cabozantinib and Vandetanib,while exhibiting comparatively safer profiles,showed moderate efficacy.These insights underscored the necessity for tailored treatment decisions that carefully weigh the benefits and risks of each TKI agent. 展开更多

Different dosage forms can significantly impact pharmacokinetics in vivo,leading to varied effects and potential adverse reactions.This study aimed to evaluate the efficacy,safety,and cost-effectiveness of isosorbide mononitrate sustained-release capsules(IMSRC)combined with conventional treatments,compared to isosorbide mononitrate tablets(IMT)combined with conventional treatments,for managing angina pectoris in patients with coronary heart diseases.A network meta-analysis(NMA)was conducted to assess the efficacy and safety of IMSRC and IMT.Relevant literature was sourced from databases,including PubMed,Embase,Cochrane Library,ScienceDirect,Web of Science,CNKI,Wanfang,and VIP,covering publications up to July 2023.The cost-effectiveness analysis(CEA)was performed from the perspective of China’s healthcare system,utilizing inputs derived from the NMA.The analysis included 15 studies.The NMA results revealed no significant difference in efficacy and safety between IMSRC plus conventional treatments and IMT plus conventional treatments.However,both combinations were more effective than conventional treatments without isosorbide mononitrate.No differences in safety were observed among the three groups.The surface under the cumulative ranking(SUCRA)of the NMA indicated that IMT had a slight edge over IMSRC in the total effective rate of angina pectoris,whereas IMSRC showed higher probabilities for markedly effective rate and ECG effective rate compared to IMT.The incidence of adverse events was ranked as IMT>conventional preparation>IMSRC.The CEA results highlighted that the incremental cost-effectiveness ratios(ICERs)for the markedly effective and total effective rates of angina pectoris were-133.41 and-260.20,respectively.The ICERs for ECG effective rates were-83.34 and-234.24,respectively.In conclusion,while IMSRC combined with conventional treatments and IMT combined with conventional treatments were similar in efficacy and safety,IMSRC proved to be more economical. 展开更多

Objectives:This study aimed to assess the impact of exercise rehabilitation during the vulnerable period on cardiac recovery(CR)outcomes in patients with acute decompensated heart failure(ADHF).Methods:Multiple databases including PubMed,Web of Science,Embase,the Cochrane Library,CINAHL,China National Knowledge Infrastructure(CNKI),Chinese Science and Technology Periodical Database(VIP),Wanfang database,SinoMed,ClinicalTrials.gov,and American Heart Association(AHA)and European Society of Cardiology(ESC)were searched for RCTs on exercise rehabilitation in ADHF patients’vulnerable period from inception to April 2,2025.The risk of bias was assessed with Cochrane Risk of Bias 2.0,and data were analyzed in RevMan 5.3.Results:A total of seven RCTs involving 946 patients were included.The results demonstrated that exercise rehabilitation training during the vulnerable period in patients with ADHF significantly increased the 6-min walk test distance(6-MWTD)(SMD=0.37;95%CI:0.09,0.65;P=0.01),short physical performance battery(SPPB)score(MD=1.26;95%CI:0.82,1.70;P<0.001)and peak oxygen consumption(VO2peak)(SMD=1.43;95%CI:0.53,2.34;P=0.002),improved quality of life(QoL)(SMD=0.85;95%CI:0.07,1.64,P=0.03),reduced depression score(MD=-0.73;95%CI:1.27,-0.18;P=0.009),frailty(MD=-0.22;95%CI:-0.48,0.05;P=0.11),and decreased 6-month all-cause readmission(OR=0.67;95%CI:0.49,0.91;P=0.01).However,no statistically significantdifferences were observed between the two groups in left ventricular ejection fraction(LVEF)(MD=0.96;95%CI:-1.84,3.77;P=0.50),6-month heart failure(HF)-related readmission(OR=1.01;95%CI:0.66,1.53;P=0.98),and all-cause mortality(OR=0.63;95%CI:0.18,2.24;P=0.47).There were no adverse events reported.Conclusions:Exercise rehabilitation during the vulnerable phase improves exercise tolerance,QoL,and depressive symptoms while reducing 6-month all-cause readmissions in ADHF patients,with no reported adverse events.Although trends toward improved LVEF,HF-related readmissions,and all-cause mortality were observed.Large-scale,high-quality studies are warranted to explore individualized responses and long-term outcomes. 展开更多

To evaluate the effects of sacubitril/valsartan and ARB on renal function in patients with and without heart failure, we conducted a comprehensive literature search using both Chinese and English databases. These included the Cochrane Library, Wanfang Database, PubMed, CNKI, Embase, and Clinical Trials. The search encompassed studies published from the inception of the databases to March 2024. Randomized controlled studies meeting the inclusion criteria were assessed for bias using the Cochrane risk of bias assessment tool. Data were analyzed using Review Manager 5.4, with relative risk (RR) as the effect indicator. Depending on the heterogeneity of the studies, either a fixed-effects model or a random-effects model was employed to combine effect sizes. Seven studies met the inclusion criteria. Compared with ARB drugs, sacubitril/valsartan showed a reduction in the deterioration of renal function (RR = 0.70, 95% CI: 0.44–1.12, P = 0.14) and acute renal function injury (RR = 0.77, 95% CI: 0.59–1.00, P = 0.05). The risk of end-stage renal disease was also lower (RR = 0.53, 95% CI: 0.30–0.96, P = 0.16). For serum creatinine levels greater than 2.5 mg/dL, the RR was 0.88 (95% CI: 0.68–1.15, P = 0.37). For a reduction in eGFR of more than 25%, the RR was 0.89 (95% CI: 0.57–1.41, P = 0.63). The incidence of serum potassium levels greater than 5.5 mmol/L was not significantly different between the groups (RR = 1.23, 95% CI: 0.86–1.75, P = 0.26), nor was the incidence of serum potassium levels greater than 6.0 mmol/L (RR = 1.06, 95% CI: 0.58–1.93, P = 0.86). However, the incidence of eGFR decreasing by more than 50% was significantly reduced (RR = 0.58, 95% CI: 0.34–0.99, P < 0.05). In conclusion, sacubitril/valsartan demonstrated a protective effect on the kidneys, effectively reducing the risk of renal deterioration and presenting a potential alternative to ARB drugs. 展开更多
