Inetetamab combined with pyrotinib and chemotherapy in the treatment of breast cancer brain metastasis: A case report

BACKGROUND Breast cancer brain metastasis(BCBM)is an advanced breast disease that is difficult to treat and is associated with a high risk of death.Patient prognosis is usually poor,with reduced quality of life.In this context,we report the case of a patient with HER-2-positive BCBM treated with a macromolecular mAb(ine-tetamab)combined with a small molecule tyrosine kinase inhibitor(TKI).CASE SUMMARY The patient was a 58-year-old woman with a 12-year history of type 2 diabetes.She was compliant with regular insulin treatment and had good blood glucose control.The patient was diagnosed with invasive carcinoma of the right breast(T3N1M0 stage IIIa,HER2-positive type)through aspiration biopsy of the ipsilateral breast due to the discovery of a breast tumor in February 2019.Immunohistochemistry showed ER(-),PR(-),HER-2(3+),and Ki-67(55-60%+).Preoperative neoadjuvant chemotherapy,i.e.,the AC-TH regimen(epirubicin,cyclophosphamide,docetaxel-paclitaxel,and trastuzumab),was administered for 8 cycles.She underwent modified radical mastectomy of the right breast in November 2019 and received tocilizumab targeted therapy for 1 year.Brain metastasis was found 9 mo after surgery.She underwent brain metastasectomy in August 2020.Immunohistochemistry showed ER(-)and PR.(-),HER-2(3+),and Ki-67(10-20%+).In November 2020,the patient experienced headache symptoms.After an examination,tumor recurrence in the original surgical region of the brain was observed,and the patient was treated with inetetamab,pyrotinib,and capecitabine.Whole-brain radiotherapy was recommended.The patient and her family refused radiotherapy for personal reasons.In September 2021,a routine examination revealed that the brain tumor was considerably larger.The original systemic treatment was continued and combined with intensity-modulated radiation therapy for brain metastases,followed by regular hospitalization and routine examinations.The patient’s condition is generally stable,and she has a relatively high quality of life.This case report demonstrates that in patients with BCBM and resistance to trastuzumab,inetetamab combined with pyrotinib and chemotherapy can prolong survival.CONCLUSION Inetetamab combined with small molecule TKI drugs,chemotherapy and radiation may be an effective regimen for maintaining stable disease in patients with BCBM.

Understanding the link between type 2 diabetes mellitus and Parkinson's disease:role of brain insulin resistance

Type 2 diabetes mellitus and Parkinson's disease are chronic diseases linked to a growing pandemic that affects older adults and causes significant socio-economic burden.Epidemiological data supporting a close relationship between these two aging-related diseases have resulted in the investigation of shared pathophysiological molecular mechanisms.Impaired insulin signaling in the brain has gained increasing attention during the last decade and has been suggested to contribute to the development of Parkinson's disease through the dysregulation of several pathological processes.The contribution of type 2 diabetes mellitus and insulin resistance in neurodegeneration in Parkinson's disease,with emphasis on brain insulin resistance,is extensively discussed in this article and new therapeutic strategies targeting this pathological link are presented and reviewed.

Safety and efficiency of Wharton’s Jelly-derived mesenchymal stem cell administration in patients with traumatic brain injury:First results of a phase I study

BACKGROUND Traumatic brain injury(TBI)is characterized by a disruption in the normal function of the brain due to an injury following a trauma,which can potentially cause severe physical,cognitive,and emotional impairment.Stem cell transplantation has evolved as a novel treatment modality in the management of TBI,as it has the potential to arrest the degeneration and promote regeneration of new cells in the brain.Wharton’s Jelly-derived mesenchymal stem cells(WJ-MSCs)have recently shown beneficial effects in the functional recovery of neurological deficits.AIM To evaluate the safety and efficiency of MSC therapy in TBI.METHODS We present 6 patients,4 male and 2 female aged between 21 and 27 years who suffered a TBI.These 6 patients underwent 6 doses of intrathecal,intramuscular(i.m.)and intravenous transplantation of WJ-MSCs at a target dose of 1×106/kg for each application route.Spasticity was assessed using the Modified Ashworth scale(MAS),motor function according to the Medical Research Council Muscle Strength Scale,quality of life was assessed by the Functional Independence Measure(FIM)scale and Karnofsky Performance Status scale.RESULTS Our patients showed only early,transient complications,such as subfebrile fever,mild headache,and muscle pain due to i.m.injection,which resolved within 24 h.During the one year follow-up,no other safety issues or adverse events were reported.These 6 patients showed improvements in their cognitive abilities,muscle spasticity,muscle strength,performance scores and fine motor skills when compared before and after the intervention.MAS values,which we used to assess spasticity,were observed to statistically significantly decrease for both left and right sides(P<0.001).The FIM scale includes both motor scores(P<0.05)and cognitive scores(P<0.001)and showed a significant increase in pretest posttest analyses.The difference observed in the participants’Karnofsky Performance Scale values pre and post the intervention was statistically significant(P<0.001).CONCLUSION This study showed that cell transplantation has a safe,effective and promising future in the management of TBI.

Chemotherapy combined with bevacizumab for small cell lung cancer with brain metastases:A case report

BACKGROUND Small cell lung cancer(SCLC)is a common and aggressive subtype of lung cancer.It is characterized by rapid growth and a high mortality rate.Approximately 10%of patients with SCLC present with brain metastases at the time of diagnosis,which is associated with a median survival of 5 mo.This study aimed to summarize the effect of bevacizumab on the progression-free survival(PFS)and overall survival of patients with brain metastasis of SCLC.CASE SUMMARY A 62-year-old man was referred to our hospital in February 2023 because of dizziness and numbness of the right lower extremity without headache or fever for more than four weeks.The patient was diagnosed with limited-stage SCLC.He received 8 cycles of chemotherapy combined with maintenance bevacizumab therapy and achieved a PFS of over 7 mo.CONCLUSION The combination of bevacizumab and irinotecan effectively alleviated brain metastasis in SCLC and prolonged PFS.

Effect Study of the Recombinant Human Brain Natriuretic Peptide in Patients with Heart Failure Combined with Hypotension

Objective: This paper aims to investigate the effect of applying recombinant human brain natriuretic peptide in patients with heart failure combined with hypotension. Recombinant human brain natriuretic peptide is a synthetic polypeptide drug that is primarily used to treat acute heart failure. Its mechanism of action closely mimics that of human endogenous brain natriuretic peptide. By binding to receptors on cardiomyocytes, it exerts its pharmacological effects. Methods: For the study, 76 heart failure patients with hypotension were selected from our hospital between May 2022 and June 2023. These patients were divided into two groups: a control group and an observation group, each comprising 38 patients. The control group received dopamine treatment, while the observation group was treated with recombinant brain natriuretic peptide. The objective was to compare the effects of the treatments in both groups by analyzing cardiac function indices and levels of vasoactive substances to identify any significant differences in outcomes. Results: The overall response rate of the patients in the observation group and the control group was 94.74% and 73.68%, significantly higher as compared with the observation group (P 0.05). After the following treatment, BNP, ANNP and urine output in the observation group were significantly different compared with the control group, of the statistical significance (P Conclusion: For the treatment of heart failure patients with hypotension, the clinical application of recombinant human brain natriuretic peptide is the most ideal, and significantly improves the cardiac function of patients, which is worth popularizing.

High sensitivity C-reactive protein and cardfiac resynchronization therapy in patients with advanced heart failure

Background The data on the prognostic values of high sensitivity C-reactive protein （hsCRP） levels in patients with advanced symp-tomatic heart failure （HF） receiving cardiac resynchronization therapy （CRT） are scarce. The aim of present study was to investigate the association of serum hsCRP levels with left ventricle reverse remodeling after six months of CRT as well as long-term outcome. Methods A total of 232 CRT patients were included. The assessment of hsCRP values, clinical status and echocardiographic data were performed at baseline and after six months of CRT. Long-term follow-up included all-cause mortality and hospitalizations for HF. Results During the mean follow-up periods of 31.3 ± 31.5 months, elevated hsCRP （〉3 mg/L） prior to CRT was associated with a significant 2.39-fold increase （P=0.006） in the risk of death or HF hospitalizations. At 6-month follow-up, patients who responded to CRT showed significant reductions or maintained low in hsCRP levels （–0.5 ± 4.1 mg/L reduction） compared with non-responders （1.7 ± 6.1 mg/L increase, P=0.018）. Com-pared with patients in whom 6-month hsCRP levels were reduced or remained low, patients in whom 6-month hsCRP levels were increased or maintained high experienced a significantly higher risk of subsequent death or HF hospitalizations （Log-rank P〈0.001）. The echocardio-graphic improvement was also better among patients in whom 6-month hsCRP levels were reduced or remained low compared to those in whom 6-month hsCRP levels were raised or maintained high. Conclusions Our findings demonstrated that measurement of baseline and follow-up hsCRP levels may be useful as prognostic markers for timely potential risk stratification and subsequent appropriate treatment strategies in patients with advanced HF undergoing CRT.

Lyophilized recombinant human brain natriuretic peptide: A promising therapy in patients with chronic heart failure

Lyophilized recombinant brain natriuretic peptide(BNP)is an exogenous peptide synthesized by artificial recombination technology,with a similar structure and similar physiological effects with the endogenous natriuretic peptide secreted by the human body.It’s main mechanism of action is to increase cyclic guanosine monophosphate by binding with its corresponding receptor in the body,regulating,thus,the imbalance of the vascular system and cardiac hemodynamics,improving the heart’s pumping capacity,and inhibiting sympathetic excitability and myocardial remodeling.Moreover,it can promote mitochondrial metabolism and enhance the use of adenosine triphosphate in cardiomyocytes.In the present study,102 chronic heart failure(HF)patients were randomly assigned to a control and an observation group consisting of 51 patients each.Patients of the control group were treated with standard HF therapy for 3 d including oral metoprolol tartrate tablets,spironolactone,and olmesartanate while patients of the observation group were administered the recombinant human BNP injection for the same time-period,plus the standard HF therapy.The recombinant human BNP group(observation group)demonstrated better physical,emotional,social,and economic scores,as well as cardiac and inflammatory biomarkers such as serum hypersensitive C-reactive protein,N-terminal pro BNP and troponin I levels,compared to the control group.Moreover,cardiac function was also improved,as left ventricular ejection fraction and stroke volume were significantly higher in the observation group than in the control group.Interestingly,adverse reactions were not different between the 2 groups.However,these results are not generalizable and the need of large multicenter randomized controlled trials examining the safety and efficacy of recombinant human BNP in HF patients is of major importance.

Beta-blocker therapy in elderly patients with renal dysfunction and heart failure

OBJECTIVE To assess the role of beta-blockers(BB)in patients with chronic kidney disease(CKD)aged≥75 years.METHODS AND RESULTS From January 2008 to July 2014,we included 390 consecutive patients≥75 years of age with ejection fraction≤35%and glomerular filtration rate(GFR)≤60 m L/min per 1.73 m^2.We analyzed the relationship between treatment with BB and mortality or cardiovascular events.The mean age of our population was 82.6±4.1 years.Mean ejection fraction was 27.9%±6.5%.GFR was 60-45 m L/min per 1.73 m^2 in 50.3%of patients,45-30 m L/min per 1.73 m^2 in 37.4%,and<30 m L/min per 1.73 m^2 in 12.3%.At the conclusion of follow-up,67.4%of patients were receiving BB.The median follow-up was28.04(IR:19.41-36.67)months.During the study period,211 patients(54.1%)died and 257(65.9%)had a major cardiovascular event(death or hospitalization for heart failure).BB use was significantly associated with a reduced risk of death(HR=0.51,95%CI:0.35-0.74;P<0.001).Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD:stage IIIa(GFR=30-45 m L/min per 1.73 m^2;HR=0.47,95%CI:0.26-0.86,P<0.0001),stage IIIb(GFR 30-45 m L/min per 1.73 m^2;HR=0.55,95%CI:0.26-1.06,P=0.007),and stages IV and V(GFR<30 m L/min per 1.73 m~2;HR=0.29,95%CI:0.11-0.76;P=0.047).CONCLUSIONS The use of BB in elderly patients with HFr EF and renal impairment was associated with a better prognosis.Use of BB should be encouraged when possible.

Preliminary Network Centric Therapy for Machine Learning Classification of Deep Brain Stimulation Status for the Treatment of Parkinson’s Disease with a Conformal Wearable and Wireless Inertial Sensor

The concept of Network Centric Therapy represents an amalgamation of wearable and wireless inertial sensor systems and machine learning with access to a Cloud computing environment. The advent of Network Centric Therapy is highly relevant to the treatment of Parkinson’s disease through deep brain stimulation. Originally wearable and wireless systems for quantifying Parkinson’s disease involved the use a smartphone to quantify hand tremor. Although originally novel, the smartphone has notable issues as a wearable application for quantifying movement disorder tremor. The smartphone has evolved in a pathway that has made the smartphone progressively more cumbersome to mount about the dorsum of the hand. Furthermore, the smartphone utilizes an inertial sensor package that is not certified for medical analysis, and the trial data access a provisional Cloud computing environment through an email account. These concerns are resolved with the recent development of a conformal wearable and wireless inertial sensor system. This conformal wearable and wireless system mounts to the hand with the profile of a bandage by adhesive and accesses a secure Cloud computing environment through a segmented wireless connectivity strategy involving a smartphone and tablet. Additionally, the conformal wearable and wireless system is certified by the FDA of the United States of America for ascertaining medical grade inertial sensor data. These characteristics make the conformal wearable and wireless system uniquely suited for the quantification of Parkinson’s disease treatment through deep brain stimulation. Preliminary evaluation of the conformal wearable and wireless system is demonstrated through the differentiation of deep brain stimulation set to “On” and “Off” status. Based on the robustness of the acceleration signal, this signal was selected to quantify hand tremor for the prescribed deep brain stimulation settings. Machine learning classification using the Waikato Environment for Knowledge Analysis (WEKA) was applied using the multilayer perceptron neural network. The multilayer perceptron neural network achieved considerable classification accuracy for distinguishing between the deep brain stimulation system set to “On” and “Off” status through the quantified acceleration signal data obtained by this recently developed conformal wearable and wireless system. The research achievement establishes a progressive pathway to the future objective of achieving deep brain stimulation capabilities that promote closed-loop acquisition of configuration parameters that are uniquely optimized to the individual through extrinsic means of a highly conformal wearable and wireless inertial sensor system and machine learning with access to Cloud computing resources.

Plasma brain natriuretic peptide and atria natriuretic peptide as predictors for diastolic heart failure in patients with type 2 diabetes mellitus

Objective To study the change of diastolic cardiac function in diabetic patients and to determine the diagnostic value of plasma brain natriuretic peptide （BNP） and atria natriuretic peptide （ANP） for diastolic heart failure in patients with type 2 diabetes mellitus. Methods Twelve healthy subjects and seventy-one diabetic patients were included in the study. Plasma BNP and ANP were measured with immtmoradiometic assay. Results Plasma levels of BNP and ANP increased significantly with increased severity of diastolic heart dysfunction. The ratio of E/A had significant negative correlation with the plasma levels ofBNP （r=0.669,P〈0.001） and ANP （r=0.579, P〈0.01）. AUC of ANP and BNP in ROC model was 91.9% and 65.3%, respectively. Conclusions The plasma level of BNP might be a valuable predictor for differential diagnosis of diastolic cardiac function in diabetic patients.

Objective: To observe the effect of insomnia patients with deficiency of heart and spleen in Germany by the therapy of ear points pressing with bean. Methods: A total of 80 cases of insomnia with deficiency of heart and spleen in Germany were divided into the observation group and the control group, with 40 cases in each group. The patients in the control group were treated with oral modified Guipi Decoction(归脾汤), while the patients in the observation group were treated with oral traditional Chinese medicine(TCM) and the therapy of ear points pressing with bean. The efficacy, sleep quality, the TCM syndromes score and the incidence of adverse reactions were compared between the two groups. Results: The effective rate in the observation group was higher than that in the control group, and there was statistical difference between the two group(P<0.05). After treatment, the Pittsburgh sleep quality index scale(PSQI) score, insomnia severity index(ISI) score and the TCM syndromes score in the two groups were decreased sharply(P<0.01), and those scores in the observation group were lower than that in the control group(P<0.05). There was no adverse reaction between the two groups. Conclusion: The therapy of ear points pressing with bean is effective on insomnia in Germany, which is worth further study and promotion.

Plasma brain natriuretic peptide level in older outpatients with heart failure is associated with physical frailty, especially with the slowness domain

Objective To determine the association between plasma brain natriuretic peptide （BNP） level in patients with heart failure （HF） and physical frailty as well as with each domain of physical frailty. Methods Two hundred and six outpatients of cardiovascular medicine aged 60 years and older who had been hospitalized for HF or had been given a prescription medication for HF were included. Physical frailty was assessed using the following five domains： slowness, weakness, exhaustion, low activity, and shrinking, according to the Cardiovascular Health Study. Patients were divided into nonfi-ailty and frailty groups according to frailty scores. Plasma BNP level was measured. The 6-min walk test was performed to measure endurance. Results Plasma BNP was significantly different between the two groups （frailty group： 158.0 i 214.7 pg/mL, nonfrailty group： 65.2 ~ 88.0 pg/mL, P 〈 0.01）. Multivariate logistic regression analysis revealed log-transformed plasma BNP （Log BNP） was significantly associated with physical frailty （OR： 1.68, 95% CI： 1.11-2.56）, and Log BNP was significantly associated with the slowness domain （walking speed 〈 1.0 m/s） of physical frailty （OR： 1.75, 95% Ch 1.15-2.67）. Additionally, Log BNP was negatively correlated to the 6-minute walk distance （6MWD） （p=0.37, P 〈 0.01）, while 6MWD was positively correlated to walking speed （p = 0.66, P 〈 0.01）. Conclusions Plasma BNP level was related to physical frailty, especially in the slowness domain. Endurance may intervene in the associations between plasma BNP level and walking speed.

Constraint-induced movement therapy promotes motor function recovery and downregulates phosphorylated extracellular regulated protein kinase expression in ischemic brain tissue of rats

Motor function impairment is a common outcome of stroke.Constraint-induced movement therapy（CIMT）involving intensive use of the impaired limb while restraining the unaffected limb is widely used to overcome the effects of＇learned non-use＇and improve limb function after stroke.However,the underlying mechanism of CIMT remains unclear.In the present study,rats were randomly divided into a middle cerebral artery occlusion（model）group,a CIMT＋model（CIMT）group,or a sham group.Restriction of the affected limb by plaster cast was performed in the CIMT and sham groups.Compared with the model group,CIMT significantly improved the forelimb functional performance in rats.By western blot assay,the expression of phosphorylated extracellular regulated protein kinase in the bilateral cortex and hippocampi of cerebral ischemic rats in the CIMT group was significantly lower than that in the model group,and was similar to sham group levels.These data suggest that functional recovery after CIMT may be related to decreased expression of phosphorylated extracellular regulated protein kinase in the bilateral cortex and hippocampi.

Brain natriuretic peptide is a potent vasodilator in aged human microcircula- tion and shows a blunted response in heart failure patients

Background Brain natriuretic peptide （BNP） is normally present in low levels in the circulation, but it is elevated in parallel with the degree of congestion in heart failure subjects （CHF）. BNP has natriuretic effects and is a potent vasodilator. It is suggested that BNP could be a therapeutic alternative in CHF. However, we postulated that the high levels of circulating BNP in CHF may downregulate the response of microvascular natriuretic receptors. This was tested by comparing 15 CHF patients （BNP 〉 3000 ng/L） with 10 matched, healthy controls. Methods Cutaneous microvascular blood flow in the forearm was measured by laser Doppler Flowmetry. Local heating （＋44°C, 10 min） was used to evoke a maximum local dilator response. Results Non-invasive iontophoretic administration of either BNP or acetylcholine （ACh）, a known endothelium-dependent dilator, elicited an increase in local flow. The nitric oxide synthase inhibitor, l-N-Arginine- methyl-ester （L-NAME）, blocked the BNP response （in controls）. Interestingly, responses to BNP in CHF patients were reduced to about one third of those seen in healthy controls （increase in flow： 251% in CHF vs. 908% in controls; P 〈 0.001）. In contrast, the vasodilator responses to ACh and to local heating were only somewhat attenuated in CHF patients. Thus, dilator capacity and nitric oxide signalling were not af- fected to the same extent as BNP-mediated dilation, indicating a specific downregulation of the latter response. Conclusions The findings show for the first time that microvascular responses to BNP are markedly reduced in CHF patients. This is consistent with the hypothesis of BNP receptor function is downregulated in CHF.

Predictors of super-response to cardiac resynchronization therapy： the significance of heart failure medication, pre-implant left ventricular geometry and high percentage of biventricular pacing

Background Super-responders （SRs） are defined as patients who show crucial cardiac function improvement after cardiac resynchro- nization therapy （CRT）. The purpose of this study is to identify and validate predictors of SRs after CRT. Methods This study enrolled 201 patients who underwent CRT during the period from 2010 to 2014. Clinical and echocardiographic evaluations were conducted before CRT and 6 months after. Patients with a decrease in New York Heart Association （NYHA） fimctional class 〉 1, a decrease in left ventricular end-systolic volume （LVESV） ≥ 15%, and a final left ventricular ejection fraction （LVEF） ≥ 45% were classified as SRs. Results 29% of the 201 patients who underwent CRT were identified as SRs. At baseline, SRs had significantly smaller left atrial diameter （LAD）, LVESV, left ventricular end-diastolic volume （LVEDV） and higher LVEF than the non-super-responders （non-SRs）. The percentage of patients using angiotensin-converting enzyme inhibitors or angiotensin receptor blockers （ACEI/ARB） was higher in SRs than non-SRs. Most SRs had Biventricular （BiV） pacing percentage greater than 98% six months after CRT. In the multivariate logistic regression analysis, the independ- ent predictors of SRs were lower LVEDV [odd ratios （OR）： 0.93; confidence intervals （CI）： 0.90-0.97], use of ACEI/ARB （OR： 0.33; CI： 0.13~3.82） and BiV pacing percentage greater than 98% （OR： 0.29; CI： 0.16~.87）. Conclusion Patients with a better compliance of ACEI/ARB and a less ectatic ventricular geometry before CRT tends to have a greater probability of becoming SRs. Higher percentage of BiV pacing is essential for becoming SRs.

Brain natriuretic peptide and optimal management of heart failure

Aside from the important role of brain natriuretic peptide (BNP) in diagnosis, and differential diagnosis of heart failure, this biological peptide has proved to be an independent surrogate marker of rehospitalization and death of the fatal disease. Several randomized clinical trials demonstrated that drugs such as beta blocker, angiotensin converting enzyme inhibitor, spiro- nolactone and amiodarone have beneficial effects in decreasing circulating BNP level during the management of chronic heart failure. The optimization of clinical decision-making appeals for a representative surrogate marker for heart failure prognosis. The serial point-of-care assessments of BNP concentration provide a therapeutic goal of clinical multi-therapy and an objective guid- ance for optimal treatment of heart failure. Nevertheless new questions and problems in this area remain to be clarified. On the basis of current research advances, this article gives an overview of BNP peptide and its property and role in the management of heart failure.

Effectiveness of cognitive behavioral therapy-based interventions on health outcomes in patients with coronary heart disease:A metaanalysis

BACKGROUND Recently,the efficacy of cognitive behavioral therapy(CBT)-based intervention on health outcomes in patients with coronary heart disease(CHD)has been recognized in randomized controlled trials(RCTs),but no comprehensive systematic review has been conducted.To address this research gap,our study aimed to evaluate whether comprehensive CBT-based interventions positively affect health outcomes in CHD patients.It was hypothesized that CBT-based interventions are effective in:(1)Reducing depression,anxiety,and stress symptoms;(2)Reducing body mass index,blood pressure,and lipid levels;and(3)Improving quality of life,and exercise endurance.AIM To verify the effectiveness of CBT-based interventions on CHD patients through a meta-analysis of previous publications.METHODS Relevant RCTs published in English were obtained by searching electronic databases,including PubMed,Embase,Cochrane Central Register of Controlled Trials,Scopus,and Proquest,with the retrieval time from inception to August 2020.The primary outcomes were psychological factors(depression,anxiety,and stress symptoms),physiological factors(body mass index,blood pressure,blood lipids).The secondary outcomes included quality of life and exercise endurance.We used Review Manager 5.3 to conduct the meta-analysis and used the Physiotherapy Evidence Database tool to evaluate the quality of studies.RESULTS A total of 22 RCTs comprising 4991 patients with CHD were included in the systematic review and meta-analysis.The main analysis revealed that CBT-based intervention can reduce depression symptoms:-2.00[95%confidence interval(CI):-2.83 to-1.16,P<0.001];anxiety symptoms:-2.07(95%CI:-3.39 to-0.75,P=0.002);stress symptoms:-3.33(95%CI:-4.23 to-2.44,P<0.001);body mass index:-0.47(95%CI:-0.81 to-0.13,P=0.006);and improve physical functioning:3.36(95%CI:1.63 to 5.10,P=0.000)and mental functioning:6.91(95%CI:4.10 to 9.73,P<0.001).Moreover,subgroup analysis results showed that CBT-based interventions were more effective for symptoms of depression and anxiety in CHD patients when individual,as opposed to group treatment,and psycho-education,behavioral and cognitive strategies were applied as the core treatment approaches.CONCLUSION CBT-based interventions are effective treatment strategies for CHD patients,significantly improving their symptoms of depression,anxiety and stress,body mass index,and health-related quality of life.

Lyophilized recombinant human brain natriuretic peptide for chronic heart failure:Effects on cardiac function and inflammation

BACKGROUND Chronic heart failure(CHF)is a serious and prevalent condition characterized by impaired cardiac function and inflammation.Standard therapy for CHF has limitations,prompting the exploration of alternative treatments.Recombinant human brain natriuretic peptide(BNP)has emerged as a potential therapy,with evidence suggesting that it can improve cardiac function and reduce inflammation in patients with CHF.However,further research is required to determine the efficacy and safety of lyophilized recombinant human BNP in CHF patients and its impact on microinflammatory status.This study aimed to investigate the effects of lyophilized recombinant human BNP therapy on CHF patients’cardiac function and microinflammatory status.AIM To investigate the effects of freeze-dried recombinant human BNP therapy on cardiac function and microinflammatory status in patients with CHF.METHODS In total,102 CHF patients admitted to our hospital from January 2021 to January 2022 were randomly assigned to control and observation groups(n=51 patients/group).The control patients were treated with standard HF therapy for 3 d,whereas the observational patients were injected with the recombinant human BNP for 3 d.Clinical efficacy,inflammatory factor levels,myocardial damage,cardiac function before and after the treatment,and adverse reactions during treatment were compared between the two groups.RESULTS The overall clinical efficacy was higher in the observation group than in the control group.Compared with baseline,serum hypersensitive C-reactive protein,N-terminal proBNP,and troponin I level,and physical,emotional,social,and economic scores were lower in both groups after treatment,with greater reductions in levels and scores noted in the observation group than in the control group.The overall incidence of adverse reactions in the observation group was not significantly different compared with that in the control group(P>0.05).CONCLUSION Freeze-dried recombinant human BNP therapy can improve heart function and enhance microinflammatory status,thereby improving overall quality of life without any obvious side effects.This therapy is safe and reliable.
