To identify and evaluate the range of adherence measures used to assess different phases of medication adherence (initiation, implementation, and discontinuation) to antidepressants, including the psychometric properties of the measures.
Methods
This systematic review followed the PRISMA statement. Medline, Embase, International Pharmaceutical Abstracts, CINAHL and PsychINFO were searched (1994–2015) for articles which reviewed or reported the psychometric properties of adherence measures in adults with unipolar depression without co-morbidity. Included articles were reviewed for the reliability and validity of their adherence measures.
Results
26 studies met the inclusion criteria. Most assessed medication adherence at implementation and/or discontinuation phases. Self-report measures were the most frequently used, followed by electronic lid devices and pharmacy records. Standardized self-report measures such as Morisky, Green, and Levine Self-Reported Medication Taking Scale (MGLS) and Antidepressant Adherence Scale (AAS) demonstrated acceptable reliability and validity, while medication claims data showed good reliability as a long-term measure.
Conclusions
Although the psychometric properties of various measures have been evaluated across the three phases of adherence, a standout measure with strong reliability and validity was not apparent. No single measure demonstrated reliability and validity throughout the adherence process. A range of different subjective and objective adherence measures is recommended to assess medication adherence across the different phases. 相似文献
Background: Interleukin-35 (IL-35) is a member of the IL-12 family of heterodimeric cytokines produced by regulatory T (Treg) cells. This immunosuppressive cytokine can prevent exaggerated inflammatory responses like those responsible for the development of rheumatoid arthritis (RA). This study aims to determine the correlation between the gene expression of Epstein–Barr virus-induced gene 3 (EBI-3) and IL-12A (p35) subunits of IL-35 in peripheral blood leukocytes with immunological and clinical parameters in RA patients.
Methods: We recruited 47 patients with RA and 44 healthy subjects. The disease activity score-28 (DAS-28) was assessed by an expert rheumatologist and the plasma levels of neopterin and anti-cyclic citrullinated peptide (anti-CCP) was measured using ELISA method also Serum rheumatoid factor (RF) was assessed by the agglutination test. For the evaluation of IL-12A and EBI-3 gene expression, we used qPCR.
Results: We did not find any significant correlation between the gene expression of IL-35 subunits and DAS-28. There was a negative correlation between the plasma levels of neopterin and the gene expression of EBI-3 (p = 0.004). Inversely, we found a positive correlation between plasma level of anti-CCP and neopterin (p < 0.001) also between RF and DAS-28 (p = 0.001).
Conclusion: Regarding the significant negative correlation between EBI-3 gene expression and plasma levels of neopterin, it can be concluded that the altered gene expression of EBI-3 may play a role in the pathogenesis of RA. 相似文献
In recent years using nanoparticle has been increased to resolve microbial resistance. It has been shown that nanomaterial such as metallic nanoparticles is the most effective in microbial cell reduction. In nanoparticle using the antimicrobial activity assay should be identified by suitable method. This review consists of introduce the available techniques for determination of Nanoantimicrobials activity, specifically metal oxide nanoparticles. Determining methods for the antimicrobial potential of nanoparticle, including the use of viable cells by exploring and indirect tests, each with unique advantages and disadvantages, such as bacterial cell enumeration, diffusion test, minimum inhibitory concentration and minimum bactericidal concentration, adenosine triphosphate assay, fluorescein diacetate (3,6-diacetylfluorescein), molecular biological techniques, and fractional inhibitory concentration index, to determine the effectiveness of test substances for synergistic, antagonistic, or additive effects, in one section. Antimicrobial activity parameters of nanoparticles, including UV illumination effect, impact of nanoparticle shape, surface modification, influence of nanoparticle size and concentration, surface defects, ion release of used nanoparticles, charge on the surface of the nanoparticles, and generation of reactive oxygen species, are described in other sections. It can be concluded that being familiar with all the existence method’s advantages, disadvantages and application range can reduce the challenge of method selection that providing relevant and reliable information about antimicrobial activity of NPs. 相似文献
Racial disparities in cancer mortality may be greater for cancers that are amenable to available early detection and treatment (amenability level). We investigated whether these patterns vary by age at cancer diagnosis.
Methods
Using 5-year relative survival rates (5Y-RSR), we classified 51 cancer sites into least amenable, partly amenable, and mostly amenable cancers (<40 %, 40–69 %, ≥70 % 5-YRS, respectively). We examined whether racial disparities in mortality rates (African-Americans, Asian/Pacific Islanders, Hispanics, whites), as estimated through Cox regression models, were modified by age at diagnosis and amenability level in 516,939 cancer cases diagnosed in 1995–1999.
Results
As compared with whites, all racial minority groups experienced higher cancer mortality rates in the youngest age group of 20–34 years. African-Americans and Hispanics diagnosed with partly and mostly amenable cancers had higher mortality rates relative to whites with cancers of the same amenability levels; further, these differences decreased in magnitude or reversed in direction with increasing age. In contrast, the racial differences in mortality were smaller and remained fairly constant across age groups for least amenable cancers. For example, in the youngest (20–34) and oldest (80–99) age groups, the adjusted hazard ratios (HRs) for African-Americans versus whites with least amenable cancers were, respectively, 1.26 (95 % CI 1.02, 1.55) and 0.90 (95 % CI 0.85, 0.96), while the HRs for African-Americans versus whites with mostly amenable cancers were 2.77 (95 % CI 2.38, 3.22) and 1.07 (95 % CI 0.98, 1.17).
Conclusions
Cancer survival disadvantage for racial minorities is larger in younger age groups for cancers that are more amenable to medical interventions.
OBJECTIVE: This study aimed to compare the systemic bioavailability of two aciclovir tablets, Rouz-Aciclovir (test) and Zovirax (reference), in 12 healthy volunteers. METHODS: In a crossover design, each subject received a single oral dose of aciclovir 400 mg followed by a 7-day washout period. Plasma concentrations of aciclovir were measured for up to 12 hours using a validated high-performance liquid chromatography method with a lower limit of quantification of 50 microg/L. RESULTS: The mean values of maximum plasma concentration (C(max)), time to C(max) (t(max)), area under the plasma concentration-time curve from time 0 to 12 hours (AUC(12)) and from time 0 to infinity (AUC(infinity)), and plasma half-life following administration of the test product were 999.6 microg/L, 2.08 h, 4911.2 microg/L . h, 5417.7 microg/L . h and 3.08 h, respectively, and for the reference product 775.8 microg/L, 2.58 h, 3862.1 microg/L . h, 4295.4 microg/L . h and 3.14 h, respectively. The test/reference geometric ratio for C(max) (90% CI) was 1.30 (97.1, 174.8). The test/reference geometric ratios for AUC(12) (90% CI) and AUC(infinity) (90% CI) were 1.26 (99.7, 159.1) and 1.24 (98.9, 155.6), respectively. Therefore, the 90% CIs of C(max), AUC(12) and AUC(infinity) were not within the acceptable range of 80 and 125 suggested by the US FDA bioequivalence guideline. CONCLUSION: The results of the present study suggest that the aciclovir test product was not bioequivalent to the reference product. The exact reasons for this remain to be determined. However, we think the difference should be attributed to the difference in the type and amounts of ingredients used in the formulation that probably affect the contact time of aciclovir with the sites of absorption in the gut. 相似文献
Noncoding RNAs (ncRNAs) are engaged in key cell biological and pathological events, and their expression alteration is connected to cancer progression both directly and indirectly. A huge number of studies have mentioned the significant role of ncRNAs in cancer prevention and therapy that make them an interesting subject for cancer therapy. However, there are several limitations, including delivery, uptake, and short half-life, in the application of ncRNAs in cancer treatment. Exosomes are introduced as promising options for the delivery of ncRNAs to the target cells. In this review, we will briefly discuss the application and barriers of ncRNAs. After that we will focus on exosome-based ncRNAs delivery and their advantages as well as the latest achievements in drugging ncRNAs with exosomes. 相似文献
Background Social media are frequently used by consumers and healthcare professionals. However, it is not clear how pharmacists use social media as part of their daily professional practice. Objective This study investigated the role social media play in pharmacy practice, particularly in patient care and how pharmacists interact online with patients and laypeople. Setting Face-to-face, telephone, or Skype interviews with practising pharmacists (n = 31) from nine countries. Method In-depth semi-structured interviews; audio-recorded, transcribed verbatim, and thematically analysed. Main outcome measure Two themes related to the use of social media for patient care: social media and pharmacy practice, and pharmacists’ online interactions with customers and the public. Results Most participants were community pharmacists. They did not provide individualized services to consumers via social media, despite most of them working in a pharmacy with a Facebook page. No participant “friended” consumers on Facebook as it was perceived to blur the boundary between professional and personal relationships. However, they occasionally provided advice and general health information on social media to friends and followers, and more commonly corrected misleading health information spread on Facebook. Short YouTube videos were used to support patient counselling in community pharmacy. Conclusions Participants recognized the potential social media has for health. However, its use to support patient care and deliver pharmacy services was very incipient. Pharmacists as medicine experts are well equipped to contribute to improvements in social media medicines-related information, learn from consumers’ online activities, and design new ways of delivering care to communities and individuals. 相似文献
BackgroundMerosin‐deficient congenital muscular dystrophy type 1A (MDC1A) is occurred by mutations in LAMA2 gene that encodes the laminin α2 chain (merosin). MDC1A is a predominant subtype of congenital muscular dystrophy. Herein, we identified two missense mutations in LAMA2 gene in compound heterozygous status in an Iranian patient with MDC1A using whole‐exome sequencing (WES).MethodsIn the present study, we evaluated genetic alterations in an Iranian 35‐month‐old boy with MDC1A and his healthy family using WES method. The identified mutations further confirmed by Sanger sequencing method. Finally, in silico analysis was conducted to further evaluation of molecular function of the identified genetic variants.ResultsWe identified two potentially pathogenic missense mutations in compound heterozygous state (c.7681G>A p.Gly2561Ser and c.4840A>G p.Asn1614Asp) in LAMA2 gene as contributing to the MDC1A phenotype. The healthy parents of our proband are single heterozygous for identified mutations. These variants were found to be pathogenic by in silico analysis.ConclusionsIn general, we successfully identified LAMA2 gene mutations in an Iranian patient with MDC1A using WES. The identified mutations in LAMA2 gene can be useful in genetic counseling, prenatal diagnosis, and predicting prognosis of MDC1A. 相似文献
Bladder cancer is common and one of the most costly cancer forms, due to a lack of curative therapies. Recently, clinical safety and efficacy of the alpha1-oleate complex was demonstrated in a placebo-controlled study of nonmuscle invasive bladder cancer. Our study investigated if long-term therapeutic efficacy is improved by repeated treatment cycles and by combining alpha1-oleate with low-dose chemotherapy. Rapidly growing bladder tumors were treated by intravesical instillation of alpha1-oleate, Epirubicin or Mitomycin C alone or in combination. One treatment cycle arrested tumor growth, with a protective effect lasting at least 4 weeks in mice receiving 8.5 mM of alpha1-oleate alone or 1.7 mM of alpha-oleate combined with Epirubicin or Mitomycin C. Repeated treatment cycles extended protection, defined by a lack of bladder pathology and a virtual absence of bladder cancer-specific gene expression. Synergy with Epirubicin was detected at the lower alpha1-oleate concentration and in vitro, alpha1-oleate was shown to enhance the uptake and nuclear translocation of Epirubicin, by tumor cells. Effects at the chromatin level affecting cell proliferation were further suggested by reduced BrdU incorporation. In addition, alpha1-oleate triggered DNA fragmentation, defined by the TUNEL assay. The results suggest that bladder cancer development may be prevented long-term in the murine model, by alpha1-oleate alone or in combination with low-dose Epirubicin. In addition, the combination of alpha1-oleate and Epirubicin reduced the size of established tumors. Exploring these potent preventive and therapeutic effects will be of immediate interest in patients with bladder cancer. 相似文献
