When the ventricular rate was controlled to below 90 bpm, the patients would almost complain of no discomfort. No severe side-effect was observed in each group.Conclusion Amiodarone and cedilanid may be the proper drugs for the treatment of paroxysmal atrial fibrillation in the elderly.The above antiarrhythmics in each therapeutic group were relatively safe and effective.展开更多

The non interven- tional ＂Transdermal Rotigotine User Surveillance Study＂ （TRUST） trial represents such a real-world study. It investigated long-term treatment with different dopamine substituting treatment regimens in 2195 PD patients （Mfiller et al., 2018）. Participation in TRUST meant that the treating neurologists were only asked to document and modify the dopaminergic drug regimen without any prior PD patient selection criteria. Thus this unique trial design reflects the real world of patient maintenance.展开更多

Descriptive cross-sectional interventional study is used. DTM （drug therapy monitoring） was conducted in 73 patients using data obtained from clinical histories and interviews. NOM were detected based on symptoms and laboratory test results. The statistical significance was 0.05. It can be found that 23 DRP were detected, primarily in the category ＂likelihood of adverse effects＂ （30.43%） causing NOM in the ＂non-quantitative safety problem＂ category. The NOM detected were related to safety （62%）, effectiveness （24.5%） and necessity （13.5%）. Of the 68.57% of pharmacist interventions accepted, 48.57% were resolved and 20% were not resolved. A simple linear correlation （r = -0.34） analysis indicated a weak association between patient age and severity ofNOM. DTM made it＇possible to detect suspected DRP and NOM, which were then prevented or resolved, improving the control of HTN and DM2 and helping ensure better drug therapy outcomes for patients.展开更多

The range of new agents available for treatment of cerebral vasospasm is expanding rapidly along with rapid advances in pharmacology and physiology that are uncovering the mechanisms of this disease. Although there are many publications for treatment of cerebral vaso-spasm, most are focusing on different aspects of vasospasm treatment and many have limited value due to insufficient quality. Moreover, the complexity of this, in many cases deleterious condition, is enormous and the information needed to understand drug effects is accordingly often not readily available in a single source. A number of pharmacological and medical therapies are currently in use or being investigated in an attempt to reverse cerebral vasospasm, but only a few have proven to be useful. Current research efforts promise the eventual production of new medical therapies. At last, recommendations for the use of different treatment stages based on currently available clinical data are provided.展开更多

A retro- spective study of the medical conditions, drug therapies, and drug therapy problems identified in 102 patients was performed. The patients were divided into young patient group （〈65 years of age） and elderly patient group （〉~ 65 years of age） in a hospital pharmacy setting. Inclusion criteria： patients who were referred by the treating doctors and received evaluation by the clinical pharmacists. Exclusion criteria： patients who were unable to or refused to be evaluated by the clinical pharmacists. We found that 1） Patients in young and elderly groups had a mean of 3 and 5 medical conditions per person, respectively （P = 0.001）. 2） On the average, they took 4 and 7 drug therapies per person, respectively. The elderly patients took a significantly higher number of drug therapies （P = 0.001）. 3） Totally 85 drug therapy problems in 7 categories were identified within 102 patients. 4） 36.8% of young patients experienced 1 to 4 drug therapy problems whereas 61.8% of elderly patient experienced I to 5 drug therapy problems. Drug therapy problems were significantly more prevalent in elderly patients （P = 0.017）. 5） The drug therapy problem by category had similar distribution in young and elderly patients. The elderly patients in this study encountered more drug therapy problems than young patients. Accordingly, more attention should be paid to elderly patients in pharmaceutical care practice.展开更多

It is not an independent disease but a clinical syndrome mostly brought about by some basic diseases such as nonspecific immunity, specific immune suppression or deficiency disease, congenital bronchopulmonary dysplasia, vitamin or microelement deficiency, or is induced by some factors such as smoking, cross infection, and nursing errors.（2） Clinically, CRRI is commonly treated by anti-infective agents, symptomatic and supportive treatment, and immune-regulatory therapy. However, the therapeutic effectiveness is always imperfect, which could even lead to a premium on asthma, or nephritis, etc.展开更多

文摘Alveolar echinococcosis(AE)is a chronic zoonotic parasitic disease caused by infection with Echinococcus multilocularis.AE is associated with a high mortality rate and poses a significant threat to human health.The primary treatment for AE is surgical resection of the lesions;however,owing to its long incubation period and insidious disease progression,many patients are diagnosed only after the onset of complications such as liver cirrhosis,jaundice,and portal hypertension,which preclude curative surgical intervention.For patients who are unwilling or unable to undergo surgery,lifelong administration of anti-AE medications is necessary.Benzimidazole compounds,such as albendazole and mebendazole,are the current mainstays of treatment,offering good efficacy.Nevertheless,these medications primarily inhibit parasite proliferation rather than eradicate the infection,and their long-term use can lead to significant drug-related toxic effects.Consequently,there is an urgent need to develop new therapeutic strategies that convey better efficacy and reduce the adverse effects associated with current treatments.Recent advancements in AE therapy include novel synthetic compounds such as antiviral agents,antibiotics,antineoplastic agents,immunosuppressants,and antiangiogenic agents,as well as natural compounds derived from traditional Chinese and Tibetan medicine.These new drugs show promising clinical potential because they interfere with parasitic metabolic pathways and cellular structures.This review aims to discuss recent research on AE drug therapy,including mechanisms of action,dosing regimens,signalling pathways,and therapeutic outcomes,with a goal of providing new insights and directions for the development of anti-AE drugs and summarizing current advancements in AE pharmacotherapy.

文摘Background:The heterogeneity of prognosis and treatment benefits among patients with gliomas is due to tumor microenvironment characteristics.However,biomarkers that reflect microenvironmental characteristics and predict the prognosis of gliomas are limited.Therefore,we aimed to develop a model that can effectively predict prognosis,differentiate microenvironment signatures,and optimize drug selection for patients with glioma.Materials and Methods:The CIBERSORT algorithm,bulk sequencing analysis,and single-cell RNA(scRNA)analysis were employed to identify significant cross-talk genes between M2 macrophages and cancer cells in glioma tissues.A predictive model was constructed based on cross-talk gene expression,and its effect on prognosis,recurrence prediction,and microenvironment characteristics was validated in multiple cohorts.The effect of the predictive model on drug selection was evaluated using the OncoPredict algorithm and relevant cellular biology experiments.Results:A high abundance of M2 macrophages in glioma tissues indicates poor prognosis,and cross-talk between macrophages and cancer cells plays a crucial role in shaping the tumor microenvironment.Eight genes involved in the cross-talk between macrophages and cancer cells were identified.Among them,periostin(POSTN),chitinase 3 like 1(CHI3L1),serum amyloid A1(SAA1),and matrix metallopeptidase 9(MMP9)were selected to construct a predictive model.The developed model demonstrated significant efficacy in distinguishing patient prognosis,recurrent cases,and characteristics of high inflammation,hypoxia,and immunosuppression.Furthermore,this model can serve as a valuable tool for guiding the use of trametinib.Conclusions:In summary,this study provides a comprehensive understanding of the interplay between M2 macrophages and cancer cells in glioma;utilizes a cross-talk gene signature to develop a predictive model that can predict the differentiation of patient prognosis,recurrence instances,and microenvironment characteristics;and aids in optimizing the application of trametinib in glioma patients.

文摘Alzheimer’s disease(AD)is a chronic neurodegenerative disease that mainly causes dementia.It is a serious threat to the health of the global elderly population.Considerable money and effort has been invested in the development of drug therapy for AD worldwide.Many drug therapies are currently under development or in clinical trials,based on two known mechanisms of AD,namely,Aβtoxicity and the abnormal Tau hyperphosphorylation.Numerous drugs are also being developed for other AD associated mechanisms such as neuroinflammation,neurotransmitter imbalance,oxidative damage and mitochondrial dysfunction,neuron loss and degeneration.Even so,the number of drugs that can successfully improve symptoms or delay the progression of the disease remains very limited.However,multi-drug combinations may provide a new avenue for drug therapy for AD.In addition,early diagnosis of AD and timely initiation of treatment may allow drugs that act on the early pathological processes of AD to help improve the symptoms and prevent the progression of the condition.

文摘BACKGROUND Treatment decision making is strictly associated with the outcomes in patients with ischemic stroke who show a large core infarct.Medical care alone may result in suboptimal treatment efficacy,and endovascular treatment may be accompanied by safety issues.Whether endovascular treatment is superior to medical care is not well investigated in the clinical studies.AIM To investigate the efficacy of endovascular treatment and drug therapy alone in mild ischemic stroke patients with large infarct cores.METHODS Fifty patients with mild ischemic stroke and 50 patients with acute ischemic stroke caused by anterior large vessel occlusion were selected at the First Affiliated Hospital of Hebei North University between January 2021 and December 2021.Patients were divided into an endovascular therapy group and a drug therapy group according to different treatment methods.In the endovascular therapy group,there were 28 patients with minor stroke and 22 patients with large infarct cores.The drug therapy group had 22 patients with minor stroke and 28 patients with large infarct cores.The National Institutes of Health Stroke Scale(NIHSS) scores were collected and compared between the two groups immediately after the operation and 24 h and 7 d after the operation.The modified Rankin scale(m RS) and/or activity of daily living were assessed at hospital discharge.RESULTS There was no significant difference in NIHSS scores between the two groups before the operation(P > 0.05).NIHSS scores were lower in the endovascular therapy group than in the drug therapy group at 24 h and 7 d after the operation and at hospital discharge(all P < 0.05).The incidence of early neurologic deterioration was significantly lower in the endovascular therapy group than in the drug therapy group(P < 0.05).At hospital discharge,the m RS score was lower in the endovascular treatment group than in the drug therapy group,and the activity of daily living score was better in the endovascular treatment group than in the drug therapy group(all P < 0.05).During a follow-up of 3 mo,17 patients(34.0%) had good prognosis(m RS ≤ 2),33 patients(66.0%) had poor prognosis(m RS > 2),and 11 patients(22.0%) died.In the medical treatment group,16 patients(m RS ≤ 2) had good prognosis(32.0%),34 patients(m RS > 2) had poor prognosis(68.0%),and 14 patients(28.0%) died.There was no significant difference in prognosis and mortality between the two groups(P > 0.05).CONCLUSION Endovascular therapy can improve NIHSS score and m RS score in patients with mild ischemic stroke and large infarct cores.It is suitable for clinical application.
文摘Objective To investigate the effectiveness and safety of various agents on paroxysmal atrial fibrillation in the elderly over 75 years old.Methods Totally 264 in-patients (75-91 years old, 185 males and 79 females) with atrial fibrillation history of less than 7 days were enrolled in this study.A total of 611 atrial fibrillation episodes were recorded, but 130 episodes (22.3%) of atrial fibrillation were auto-converted to sinus rhythm.The rest 481 episodes of atrial fibrillation were divided into six groups based on the drug used.Results The cardioversion ratio of atrial fibrillation were 9.5%, 46.9%, 71.7%, 55.9%, 32.7%, and 73.6% in control, cedilanid, amiodarone, propafenone, verapamil, and quinidine groups, respectively.Ventricular rate control were 5.4%, 83.6%, 84.9%, 77.9%, 78.8%, and 11.3% in those groups, respectively.The total effective rates of amiodarone and cedilanid groups were the highest. When the ventricular rate was controlled to below 90 bpm, the patients would almost complain of no discomfort. No severe side-effect was observed in each group.Conclusion Amiodarone and cedilanid may be the proper drugs for the treatment of paroxysmal atrial fibrillation in the elderly.The above antiarrhythmics in each therapeutic group were relatively safe and effective.
文摘Prospective real-world data from large patient samples, which re- port on the long-term effectiveness of the employed different drug therapies, are rare in Parkinson＇s disease （PD）. The non interven- tional ＂Transdermal Rotigotine User Surveillance Study＂ （TRUST） trial represents such a real-world study. It investigated long-term treatment with different dopamine substituting treatment regimens in 2195 PD patients （Mfiller et al., 2018）. Participation in TRUST meant that the treating neurologists were only asked to document and modify the dopaminergic drug regimen without any prior PD patient selection criteria. Thus this unique trial design reflects the real world of patient maintenance.
文摘The aim of this paper is to detect, prevent and resolve DRP （drug-related problems） and NOM （negative outcomes associated with medication） in hospitalized patients with DM2 （type 2 diabetes） with HTN （hypertension） in a tertiary care clinic. Descriptive cross-sectional interventional study is used. DTM （drug therapy monitoring） was conducted in 73 patients using data obtained from clinical histories and interviews. NOM were detected based on symptoms and laboratory test results. The statistical significance was 0.05. It can be found that 23 DRP were detected, primarily in the category ＂likelihood of adverse effects＂ （30.43%） causing NOM in the ＂non-quantitative safety problem＂ category. The NOM detected were related to safety （62%）, effectiveness （24.5%） and necessity （13.5%）. Of the 68.57% of pharmacist interventions accepted, 48.57% were resolved and 20% were not resolved. A simple linear correlation （r = -0.34） analysis indicated a weak association between patient age and severity ofNOM. DTM made it＇possible to detect suspected DRP and NOM, which were then prevented or resolved, improving the control of HTN and DM2 and helping ensure better drug therapy outcomes for patients.
文摘In this manuscript a comprehensive coverage of recent developments in the drug therapy of vasospasm while providing the background information that neuroscientists need to understand its rationale. The range of new agents available for treatment of cerebral vasospasm is expanding rapidly along with rapid advances in pharmacology and physiology that are uncovering the mechanisms of this disease. Although there are many publications for treatment of cerebral vaso-spasm, most are focusing on different aspects of vasospasm treatment and many have limited value due to insufficient quality. Moreover, the complexity of this, in many cases deleterious condition, is enormous and the information needed to understand drug effects is accordingly often not readily available in a single source. A number of pharmacological and medical therapies are currently in use or being investigated in an attempt to reverse cerebral vasospasm, but only a few have proven to be useful. Current research efforts promise the eventual production of new medical therapies. At last, recommendations for the use of different treatment stages based on currently available clinical data are provided.

文摘We propose a mathematical model studying a within-host infection dynamics of SARSCoV-2 in pneumocytes.This model incorporates immune response,vaccination and antiviral drugs.The crucial properties of the model-the existence,positivity and boundary of solutions are established.Equilibrium points and the basic reproduction number are calculated.The stability of each equilibrium point is analyzed.Optimal control is applied to the model by adding three control variables:vaccination,treatment by Favipiravir and treatment by Molnupiravir.Numerical results show that each individual control could reduce SARS-CoV-2 infection in some aspects;however,with a combination of three controls,we obtain the best results in reducing SARS-CoV-2 infection.This study has emphasized the importance of prevention by vaccine and the antiviral treatments.
文摘We evaluated the frequency and category distribution of drug therapy problems in young and elderly patients. A retro- spective study of the medical conditions, drug therapies, and drug therapy problems identified in 102 patients was performed. The patients were divided into young patient group （〈65 years of age） and elderly patient group （〉~ 65 years of age） in a hospital pharmacy setting. Inclusion criteria： patients who were referred by the treating doctors and received evaluation by the clinical pharmacists. Exclusion criteria： patients who were unable to or refused to be evaluated by the clinical pharmacists. We found that 1） Patients in young and elderly groups had a mean of 3 and 5 medical conditions per person, respectively （P = 0.001）. 2） On the average, they took 4 and 7 drug therapies per person, respectively. The elderly patients took a significantly higher number of drug therapies （P = 0.001）. 3） Totally 85 drug therapy problems in 7 categories were identified within 102 patients. 4） 36.8% of young patients experienced 1 to 4 drug therapy problems whereas 61.8% of elderly patient experienced I to 5 drug therapy problems. Drug therapy problems were significantly more prevalent in elderly patients （P = 0.017）. 5） The drug therapy problem by category had similar distribution in young and elderly patients. The elderly patients in this study encountered more drug therapy problems than young patients. Accordingly, more attention should be paid to elderly patients in pharmaceutical care practice.
文摘AIM To assess the outcomes of drug therapy(DT)followed by pancreatic endotherapy for continuing painful episodes in recurrent acute pancreatitis.METHODS DT comprised of pancreatic enzymes and antioxidants failing which,endotherapy(ET;pancreatic sphincterotomy and stent placement)was done.The frequency of pain,its visual analogue score(VAS),quality of life(Qo L),serum C peptide and faecal elastase were compared between baseline and after 1 year of follow up in all patients and in the two subgroups on DT and ET.Response was defined as at least 50%reduction in the severity of pain to below a score of 5.RESULTS Of the thirty nine patients analysed,21(53.9%)responded to DT and 18(46.1%)underwent ET.The VAS for pain(7.0±2.0 vs 1.3±2.5,P<0.001)and the number of days with pain per month decreased[1.0(1.0,2.0)vs 1.0(0.0,1.0),P<0.001],and the Qo L scores[55.0(44.0,66.0)vs 38.0(32.00,51.00),P<0.01]improved significantly during follow up.Similar significant improvements were seen in patients in the subgroups of DT and ET except for Qo L in ET.The serum C-peptide(P=0.001)and FE(P<0.001)levels improved significantly in the entire group and in the two subgroups of patients except for the C peptide levels in patients on DT.CONCLUSION A standardised protocol of DT,followed by ET decreased the intensity and frequency of pain in recurrent acute pancreatitis,enhanced Qo L and improved pancreatic function.

文摘Children recurrent respiratory infection （CRRI） indicates that children suffer from frequent infections along the upper or lower respiratory tract for a certain number of times. It is not an independent disease but a clinical syndrome mostly brought about by some basic diseases such as nonspecific immunity, specific immune suppression or deficiency disease, congenital bronchopulmonary dysplasia, vitamin or microelement deficiency, or is induced by some factors such as smoking, cross infection, and nursing errors.（2） Clinically, CRRI is commonly treated by anti-infective agents, symptomatic and supportive treatment, and immune-regulatory therapy. However, the therapeutic effectiveness is always imperfect, which could even lead to a premium on asthma, or nephritis, etc.
文摘Parkinson`s disease(PD)is a progressive,disabling neurodegenerative disorder with onset of motor and non-motor features.Both reduce quality of life of PD patients and cause caregiver burden.This review aims to provide a survey of possible therapeutic options for treatment of motor and non motor symptoms of PD and to discuss their relation to each other.MAO-B-Inhibitors,NMDA antagonists,dopamine agonists and levodopa with its various application modes mainly improve the dopamine associated motor symptoms in PD.This armentarium of PD drugs only partially influences the onset and occurrence of non motor symptoms.These PD features predominantly result from non dopaminergic neurodegeneration.Autonomic features,such as seborrhea,hyperhidrosis,orthostatic syndrome,salivation,bladder dysfunction,gastrointestinal disturbances,and neuropsychiatric symptoms,such as depression,sleep disorders,psychosis,cognitive dysfunction with impaired execution and impulse control may appear.Drug therapy of these non motor symptoms complicates long-term PD drug therapy due to possible occurrence of drug interactions,-side effects,and altered pharmacokinetic behaviour of applied compounds.Dopamine substituting compounds themselves may contribute to onset of these non motor symptoms.This complicates the differentiation from the disease process itself and influences therapeutic options,which are often limited because of additional morbidity with necessary concomitant drug therapy.
文摘Background Owing to complex treatment,critically ill children may experience alterations in their vital parameters.We investigated whether such hemodynamic alterations were temporally and causally related to drug therapy.Methods In a university pediatric intensive care unit,we retrospectively analyzed hemodynamic alterations defined as values exceeding the limits set for heart rate(HR)and blood pressure(BP).For causality assessment,we used the World Health Organization–Uppsala Monitoring Center(WHO–UMC)system,which categorizes the probability of causality as“certain,”“probable,”“possible,”and“unlikely.”Results Of 315 analyzed patients with 43,200 drug prescriptions,59.7%experienced at least one hemodynamic alteration;39.0%were affected by increased HR,19.0%by decreased HR,18.1%by increased BP,and 16.2%by decreased BP.According to drug information databases,83.9%of administered drugs potentially lead to hemodynamic alterations.Overall,88.3%of the observed hemodynamic alterations had a temporal relation to the administration of drugs;in 80.2%,more than one drug was involved.Based on the WHO–UMC system,a drug was rated as a“probable”causing factor for only 1.4%of hemodynamic alterations.For the remaining alterations,the probability ratings were lower because of multiple potential causes,e.g.,several drugs.Conclusions Critically ill children were frequently affected by hemodynamic alterations.The administration of drugs with potentially adverse effects on hemodynamic parameters is often temporally related to hemodynamic alterations.Hemodynamic alterations are often multifactorial,e.g.,due to administering multiple drugs in rapid succession;thus,the influence of individual drugs cannot easily be captured with the WHO–UMC system.
文摘With 185 million people chronically infected globally,hepatitis C is a leading bloodborne infection.All-oral regimens of direct acting agents have superior efficacy compared to the historical interferon-based regimens and are significantly more tolerable.However,trials of both types of regimens have often excluded patients on immunosuppressive medications for reasons other than organ transplantation.Yet,these patients-most often suffering from malignancy or autoimmune diseases-could stand to benefit from these treatments.In this study,we systematically review the literature on the treatment of hepatitis C in these neglected populations.Research on patients with organ transplants is more robust and this literature is reviewed here non-systematically.Our systematic review produced 2273 unique works,of which 56 met our inclusion criteria and were used in our review.The quality of data was low;only 3 of the 56 studies were randomized controlled trials.Sustained virologic response was reported sporadically.Interferon-containing regimens achieved this end-point at rates comparable to that in immunocompetent individuals.Severe adverse effects and death were rare.Data on all-oral regimens were sparse,but in the most robust study,rates of sustained virologic response were again comparable to immunocompetent individuals (40/41).Efficacy and safety of interferoncontaining regimens and all-oral regimens were similar to rates in immunocompetent individuals;however,there were few interventional trials.The large number of case reports and case series makes conclusions vulnerable to publication bias.While firm conclusions are challenging,given the dearth of high-quality studies,our results demonstrate that antiviral therapy can be safe and effective.The advent of all-oral regimens offers patients and clinicians greatly increased chances of cure and fewer side effects.Preliminary data reveal that these regimens may confer such benefits in immunosuppressed individuals as well.More prospective interventional trials would greatly benefit the many patients with chronic hepatitis C on immunosuppressive therapies.

文摘Tumor models in vitro are conventional methods for developing anti-cancer drugs,evaluating drug delivery,or calculating drug efficacy.However,traditional cell line-derived tumor models are unable to capture the tumor heterogeneity in patients or mimic the interaction between tumors and their surroundings.Recently emerging patient-derived preclinical cancer models,including of patient-derived xenograft(PDX)model,circulating tumor cell(CTC)-derived model,and tumor organoids-on-chips,are promising in personalized drug therapy by reca-pitulating the complexities and personalities of tumors and surroundings.These patient-derived models have demonstrated potential advantages in satisfying the rigorous demands of specificity,accuracy,and efficiency necessary for personalized drug therapy.However,the selection of suitable models is depending on the specific therapeutic requirements dictated by cancer types,progressions,or the assay scale.As an example,PDX models show remarkable advantages to reconstruct solid tumors in vitro to understand drug delivery and metabolism.Similarly,CTC-derived models provide a sensitive platform for drug testing in advanced-stage patients,while also facilitating the development of drugs aimed at suppressing tumor metastasis.Meanwhile,the demand for large-scale testing has promoted the development of tumor organoids-on-chips,which serves as an optimal tool for high-throughput drug screening.This review summarizes the establishment and development of PDX,CTC-derived models,and tumor organoids-on-chips and addresses their distinctive advantages in drug discovery,sensitive testing,and screening,which demonstrate the potential to aid in the selection of suitable models for fundamental cancer research and clinical trials,and further developing the personalized drug therapy.
