The study aim was to evaluate patient acceptance and content with remote follow-up (FU) of their implantable cardioverter defibrillator (ICD) and to estimate patients?? wish for changes in remote follow-up routines.
Methods
Four hundred seventy-four ICD patients at the device follow-up clinic at Rigshospitalet using CareLink? (Medtronic) remote follow-up, who had made ??2 transmissions, received a questionnaire.
Results
Three hundred eighty-five patients (81.2%) answered. Mean time with ICD was 56?±?45?months and mean age was 62?±?13?years; 80% was male. Diagnosis related to ICD implant was: ischemic heart disease in 56% and dilated cardiomyopathy in 21%. Twenty-six percent had primary prophylactic indication. Mean time on remote FU was 16.4?±?6.9?months. Mean time spent on in-clinic FU (two-way transport and FU) was 4?h and 36?min?±?7?h and 50?min, excluding 12 patients from Greenland and Faroe Islands. Ninety-five percent of the patients was very content or content with remote FU compared to in-clinic FU; 3% was less content and 2% was not content. For scheduled transmissions, 21% of the patients wished for a faster reply (sms or e-mail) compared to current practice with a letter. Eighty-four percent preferred more detailed information concerning ICD leads, battery status, and ICD therapies. A total of 96 patients (25%) had performed extra unscheduled remote transmissions: 20 due to shock, 20 due to alarm, 35 due to palpitations, and 18 for other or combined reasons.
Conclusion
Ninety-five percent of the patients were content with the remote FU. Only 25% had unscheduled transmissions and most unscheduled transmissions were for appropriate reasons. Eighty-four percent of the patients wished for a more detailed response and 21% wished for a faster reply after routine transmissions. 相似文献
Background: Trefoil factors (TFFs) are secreted molecules that are involved in cytoprotection against tissue damage and the immune response. TFFs have been detected in saliva and oral tissues, but their clinical significance has never been investigated in patients with chronic periodontitis. The objective of this study is to determine whether TFF expression in saliva and gingival tissues is associated with periodontal pathology. Methods: Saliva and gingival tissue samples were collected from 25 non‐periodontitis individuals and 25 patients with chronic periodontitis (CP). Enzyme‐linked immunosorbent assay and immunohistochemical methods were used to evaluate the expression of TFFs (TFF1, TFF2, and TFF3) in saliva and gingival tissues, respectively. Periodontopathic bacteria were quantified by real‐time polymerase chain reaction. Results: Reduced salivary TFF1 and TFF3 concentrations were observed in patients with CP (P = 0.003 and P <0.001, respectively). Decreased TFF3 expression in gingival tissues of patients with CP was demonstrated (P = 0.041). Levels of salivary TFF3 concentrations were negatively correlated with periodontal pathology and number of Porphyromonas gingivalis and Tannerella forsythia (formerly known as Bacteroides forsythus). Conclusions: Altered expression of TFFs in saliva and gingival tissues was detected in patients with CP. The results suggest that TFF3 may be involved in the pathogenesis of periodontal disease. 相似文献
Introduction: There have been numerous clinical trials of CDK4/6 inhibitors performed on various carcinomas including breast cancer. One such inhibitor tested and which has ongoing clinical trials for breast cancer is abemaciclib. Abemaciclib is a molecular-targeted agent that targets basic cell cycle regulatory mechanisms.
Areas covered: This review discusses the available clinical data and ongoing clinical trials of abemaciclib in breast cancer.
Expert opinion: Abemaciclib has demonstrated a clear anti-tumour effect and manageable toxicity against HR-positive, HER2-negative breast cancer in many clinical trials and is expected to be an important standard therapy. However, currently, besides oestrogen receptor expression, there is a definite lack of predictive biomarkers for response and/or tolerance to abemaciclib, which is important for patient selection. Another problem is that its contribution to overall survival (OS) has not been shown. And while two large the phase 3 study highlighted the anti-tumour effect of abemaciclib, the OS results are awaited. Furthermore, the effect on brain metastases is expected to be unique to abemaciclib as the response of brain metastasis in HR-positive breast cancer patients has been confirmed in a few cases with case collection still ongoing. 相似文献

Piperlonguminine (PL), a major alkaloid isolated from Piper longum fruits, shows several biological activities including anti-tumor, anti-hyperlipidemic and anti-inflammatory effects. Although there have been studies of the biological effects of PL, the potential drug-interaction effect of PL following evaluation of inhibitory effects of cytochrome P450 (CYP) activities was not investigated. Here, to investigate the inhibitory effects of PL on the activities of CYP isoforms, CYP inhibition assays were conducted using a cocktail of probe substrates in pooled human liver microsome (HLMs) and human recombinant cDNA-expressed CYP. PL strongly inhibited CYP1A2-mediated phenacetin O-deethylation with an IC50 value of 8.8 μM, as NADPH-independent inhibition, while other CYPs were not significantly inhibited. A Lineweaver–Burk plot resulted in the inhibition mechanism of PL being divided into two different modes, reversible competitive inhibition in a low concentration range of 0–16 μM with a Ki value of 1.39 μM and uncompetitive inhibitory behavior at a high concentration range of 16–40 μM. In addition, PL only decreased CYP 1A2-catalyzed phenacetin O-deethylase activity with IC50 values of 10.0 μM in human recombinant cDNA-expressed 1A2, not 1A1. Overall, this is the first investigation of potential herb–drug interactions associated with PL conducted by identifying the competitive inhibitory effects of PL on CYP1A2 in HLMs. 相似文献
STUDY OBJECTIVE - To examine the effect of 9-amino-1,2,3,4-tetrahydroacridine (THA), a compound similar to the K+ blocker 4-aminopyridine, on potassium channels in the sinoatrial node. DESIGN - The pacemaking portion of rabbit sinoatrial nodes was studied using the double microelectrode voltage clamp method in the presence of THA at various concentrations. MEASUREMENTS AND RESULTS - Above 1 mumol.litre-1, THA prolonged the spontaneous cycle length and the transmembrane action potential duration at 50% repolarisation. Above 10 mumol.litre-1, the compound also decreased the maximum rate of rise, the action potential amplitude, and the rate of diastolic depolarisation. Under voltage clamp conditions, THA reduced the time dependent K+ current (IK) in a dose dependent manner. Neither the decay process of IK nor its activation process were altered by THA. CONCLUSIONS - THA depresses sinoatrial node IK without changing its kinetics. Thus it may inhibit the open state of the potassium channels. 相似文献
To investigate the relationship between plasma levels and coronary vasodilation after administration of isosorbide dinitrate (ISDN), the plasma concentration and diarneters of six segments of the left coronary artery were measured before and after sublingual (SL) ISDN (5 mg) and left intracoronary (IC) administration of ISDN (3 mg) in 12 patients. After SL-ISDN, the systolic aortic pressure decreased with no significant concomitant changes in heart rate or diastolic aortic pressure. After IC-ISDN, all hemodynamic parameters showed significant changes, and these were greater after IC-ISDN than those after SL-ISDN. The individual mean vasodilation of six segments induced by SL- and IC-ISDN, were 23± 9 and 35± 11% (p<0.01), respectively. Before SL-ISDN, ISDN was not detected in plasma. After SL- and IC-ISDN, however, the plasma values of the ISDN were 36.1± 53.3 and 101.5± 90.0 ng/ml (p<0.01), respectively. Thus, both coronary vasodilative responses and plasma ISDN levels after IC-ISDN were significantly greater than those after SL-ISDN. However, neither the individual mean coronary vasodilation nor the hemodynamic changes correlated significantly with plasma ISDN levels. Consequently, with administration of the same dose, the coronary vasodilative response to ISDN did not correlate with plasma levels. Furthermore, IC-ISDN dilates coronary arteries more effectively than SL-ISDN. 相似文献
