ObjectivesThe aim of this study was to explore elderly patients’ beliefs about medicines in general, and specific towards their treatment and the relationship between beliefs and adherence.MethodsA cross-sectional study was performed by administering a questionnaire developed to meet the study’s objectives. Elderly patients were recruited from three different settings.Results167 patients agreed to participate to our study, having a mean age of 73 years. Patients were aware of the necessity for treatment, but they also showed concern over the potential for the adverse outcomes. Only 15% of the patients were completely accepting their treatment having high necessity and low concerns, while 40% were ambivalent, having high necessity beliefs, but also high concerns, with 89% being adherent in this group. Overall, higher adherence was significantly correlated with higher necessity and with higher necessity-concern differential.ConclusionPatients beliefs have an impact on adherence, thus patients’ concerns and necessities should be addressed in order to improve adherence and treatment outcome.Practice implicationsHigher necessity positively influenced adherence to treatment, suggesting the fact that healthcare professionals could improve patients’ adherence by outlining and educating the patients on the necessity of the treatment, while also managing patients’ concerns. 相似文献
ObjectiveTo review type 1 hypersensitivity reactions and anaphylaxis to checkpoint inhibitor–monoclonal antibodies and its management with drug desensitization.Data SourcesEnglish-language literature on MEDLINE regarding hypersensitivity, anaphylaxis, and checkpoint inhibitor–monoclonal antibodies.Study SelectionsReferences were selected based on relevance, novelty, robustness, and applicability.ResultsThere are well-known tissue toxicities associated to checkpoint inhibitors, but hypersensitivity reactions and anaphylaxis have been underreported. The presentation of these reactions is based on clinical phenotypes with underlying endotypes identified by specific biomarkers. Drug desensitizations have been successfully applied to checkpoint inhibitor drugs to allow patients with cancer to receive first-line therapies. This review provides current best practices for the recognition and diagnosis of hypersensitivity reactions and anaphylaxis to checkpoint inhibitors and their management using drug desensitization.ConclusionHypersensitivity reactions and anaphylaxis have been identified as potential adverse effects induced by checkpoint inhibitor–monoclonal antibodies. Drug desensitization is a safe and effective treatment option for patients who experience hypersensitivity reactions in need of these monoclonal antibodies to improve cancer outcomes. 相似文献
The effects of anesthetics on cytokine release in patients without comorbidities who undergo minor surgery are not well defined. We compared inflammatory cytokine profiles in adult patients undergoing minimally invasive surgery who received isoflurane or propofol anesthesia.
Methods
Thirty-four patients without comorbidities undergoing minor surgery were randomly assigned to receive an inhaled anesthetic (isoflurane; n = 16) or an intravenous anesthetic (propofol; n = 18). Blood samples were drawn before premedication and anesthesia (T1), 120 min after anesthesia induction (T2), and on the first post-operative day (T3). Plasma concentrations of interleukins (IL-) 1β, 6, 8, 10 and 12 and tumor necrosis factor (TNF)-α were measured using flow cytometry.
Results
The pro-inflammatory cytokine IL-6 was increased in the isoflurane group at T2 and T3 compared to T1 (P < 0.01). In the propofol group, IL-6 and IL-8 were significantly increased at T3 compared to T1. However, there were no significant differences in cytokine concentrations between the isoflurane and propofol groups.
Conclusion
An inflammatory response occurred earlier in patients who received an inhaled agent compared with an intravenous anesthetic, but no differences in plasma cytokine profiles were evident between isoflurane and propofol anesthesia in patients without comorbidities undergoing minimally invasive surgeries. 相似文献
BackgroundAtherosclerotic cardiovascular disease is a chronic inflammatory condition. Thiazolidinediones (TZDs) are used to enhance sensitivity to insulin and have demonstrated a protective effect over a variety of cardiovascular markers and risk factors. Controversially, the TZDs are associated with the development of heart failure. Thus, lines of research have invested in the search for new molecules in order to obtain more selective and less harmful treatment alternatives for the pathogenesis of atherosclerosis and its risk factors.MethodsAnimals were fed a diet rich in fat for 10 weeks. In the last 2 weeks, animals received either pioglitazone, LPSF/GQ-02, or LPSF/GQ-16 daily through gavage. At the end of the treatment, blood was collected for biochemical analysis and the aortas were dissected for subsequent analyses.ResultsNo changes in the blood lipid profile were found following the use of the drugs in comparison to the control. However, the new thiazolidine derivatives were more efficient in improving insulin resistance in comparison to pioglitazone and the control group. Morphometric analyses revealed that neither pioglitazone nor LPSF/GQ16 led to satisfactory effects over atherosclerosis. However, LPSF/GQ-02 led to a reduction in area of the atherosclerotic lesions. Ultrastructural analyses revealed extensive degeneration of the endothelium and an increase in apoptotic cells in the subendothelial space following the use of pioglitazone and LPSF/GQ-16. However, LPSF/GQ-02 caused minimal cell alterations in the aortic endothelium. Regarding markers, endothelial nitric oxide synthase (eNOS) and matrix metalloproteinase 9 (MMP-9), LPSF/GQ-16, and pioglitazone exerted similar effects, increasing the expression of MMP-9, and had no effect on the expression of eNOS compared with the control group. On the other hand, LPSF/GQ-02 was effective in reducing the expression of MMP-9 and increased eNOS significantly.ConclusionsThe results suggest that the new thiazolidine derivative LPSF/GQ-02 is a promising candidate for the treatment of atherosclerosis. 相似文献
BackgroundDuring dengue infection increase in plasma level of various substances have been reported. Some of those molecules are related to the virus biology and others result of the interaction virus–host. Nonstructural protein-1 (NS1) secreted by dengue virus has been reported to have a role in dengue pathogenesis. NS1 is capable of interacting with complement to evade viral clearance. However, there is little information about the presence of serum NS1 and the levels of other molecules related to dengue pathogenesis.ObjectivesThe aim of this study was to determine the association of the NS1 status and the circulating levels of interleukin-17 (IL-17), C-reactive protein (CRP), C3 and C4 in acute dengue.Study designIn this study the serum presence of NS1, IL-17, CRP, C3 and C4 was determined in children with acute dengue. IL-17, CRP, anti dengue-IgG content was measured by ELISA, C3 and C4 levels by an immunoturbidimetric assay and NS1 by an immunochromatographic assay.ResultsAll patients were positive for dengue infection as shown by antibodies anti-dengue and/or virus isolation. Increased levels of IL-17, CRP and C4 no related to the presence of NS1 were found in the patients. Values of C3 remained similar to controls.ConclusionsThese findings suggest that NS1 does not module the production of studied molecules during dengue infection. 相似文献
The present study aimed to determine the effectiveness of sclerotherapy using NBCA (Histoacryl Blue®; B. Braun, Melgungen, Germany), with or without hydrodissection, for the treatment of simple renal cysts. Materials and Methods: Patients who presented to an interventional radiology clinic for the diagnosis of symptomatic renal cysts which had previously been identified at an outpatient clinic were selected for inclusion in this study. A total of 28 patients were randomly divided into 2 groups, based on whether or not they underwent hydrodissection along with ultrasound-guided NBCA-based sclerotherapy. Sonographs were performed at 0, 7, and 180 days post-procedure to record the residual volume of the renal cysts and to determine the efficacy of the procedure. Results: A total of 32 cysts in 28 patients were treated with sclerotherapy, 18 (64%) females and 10 (36%) males. The average age of the patients was 61.8 years (range: 33–89 years). All patients reported an improvement in symptoms associated with the existing renal cysts at 7 and 180 days post-procedure, and at 7 days post-procedure a statistically significant reduction in cyst volume was observed (all patients: 96.8%; group A: 96%; group B: 97.6%). The reduced cyst volume was still observed 180 days post-procedure (all patients: 98.6%; group A: 98.2%; group B: 98.9%). There was no significant difference between the two treatment groups. Conclusion: There is a significant and persistent reduction in the volume of renal cysts, in addition to an improvement of the associated symptoms, after treatment with NBCA-based sclerotherapy, with or without hydrodissection. 相似文献
To perform a systematic review of the literature, investigating the influence of tooth mineral tissues genes on dental caries.
Materials and methods
Five databases were searched. Only human studies with cross-sectional, longitudinal, and case-control design were included. Meta-analysis was performed for each polymorphism, providing allele and genotype estimates. A meta-analysis was performed, pooling several polymorphisms for each gene. A Funnel Plot and Egger’s test were also performed.
Results
A total of 1124 records were found. Of these, 25 papers were included in the systematic review and 18 in the meta-analysis. Most of the studies (52%) were of medium quality. With regard to the allele analysis, the T allele of rs134136 (TFIP11) (OR 1.51; 95%CI 1.02–2.22) showed an association with high experience of caries and the summarization of polymorphisms investigated in the TFIP11 gene, after exclusion of SNP linkage disequilibrium, showed an association with caries experience (OR 1.64; 95%CI 1.08–2.50). An analysis of the homozygous genotype did not show any significant association. The pooled SNPs of AMBN showed associations with caries (OR 0.45; 95%CI 0.29–0.72). The pooled polymorphisms of AMELX were associated with caries experience (OR 1.78; 95%CI 1.23–2.56). In the analysis of the homozygous genotype, no SNP showed a significant association. Egger’s test showed no significant publication bias for all models (p > 0.05).
Conclusion
The present findings showed that the genes TFIP11, AMBN, and AMELX play an important role in dental caries.
Clinical relevance
Several single nucleotide polymorphisms related to the genes in the formation of tooth mineral are linked to the occurrence of dental caries, and these genes have proved to be important for an explanation of differences in the risk of dental caries.
