RESUMO

The objective of this study was to assess online American patient education material (PEM) related to eye cancers in order to determine the quality of the content and appropriateness of the contents' reading level as it relates to the American population. PEMs were extracted from fifteen American cancer and ophthalmology associations and evaluated for their reading level using ten validated readability scales. PEMs then had all words extracted and evaluated for their difficulty and familiarity. The quality of the PEMS were assessed according to DISCERN, Heath On the Net Foundation Code of Conduct (HONCode), and JAMA benchmarks. Overall, online PEMs from the associations were written at a 11th grade reading level, which is above the recommended 6th grade reading level. The difficult word analysis identified that 26% of words were unfamiliar. Only one of the fifteen association held a HONCode certification while no organization met the standards of all four JAMA benchmarks. The average score for DISCERN was 2.4 out of a total of 5 for the fifteen questions related to treatment option information quality. Consideration should be made to create PEMs at an appropriate grade reading level to encourage health literacy and ultimately promote health outcomes. Associations should also focus on incorporating easily identifiable quality indicators to allow patients to better identify reputable resources.

RESUMO

Patient education materials (PEM)s were extracted from provincial cancer agencies to determine their organizational health literacy by evaluating the quality, actionability, and functional accessibility (e.g., readability and understandability) of their PEMs. PEMs from 10 provincial agencies were assessed for their grade reading level (GRL), using eight numerical and two graphical readability scales, and underwent a difficult word analysis. The agencies were assessed for PEM quality using two methods (JAMA benchmarks and DISCERN), while actionability and understandability were assessed using the Patient Education Materials Assessment Tool (PEMAT). Seven hundred and eighty-six PEMs were analyzed. The overall average GRL was 9.3 ± 2.1, which is above the recommended 7th GRL for health information. The difficult word analysis showed that 15.4% ± 5.1% of texts contained complex words, 35.8% ± 6.8% of texts contained long words, and 24.2% ± 6.6% of texts contained unfamiliar words. Additionally, there was high overlap between the most frequently identified difficult words in the PEMs and the most frequently misunderstood words by cancer patients identified in the literature. Regarding quality indicators, no agency displayed all four indicators according to the JAMA benchmarks and DISCERN scores ranged between 38 (poor) to 66 (excellent). PEMAT scores ranged between 68% to 88% for understandability and 57% to 88% for actionability. PEMs continue to be written at a level above the recommended GRL across all provinces, and there was overall high variability in the quality, understandability, and actionability of PEMs among provincial agencies. This represents an opportunity to optimize materials, thus ensuring understanding by a wider audience and improving health literacy among Canadian cancer patients.

RESUMO

Zein can be utilized to form nanoscale particles for drug delivery applications. Despite the ease of synthesis, these particles often aggregate when exposed to physiologically relevant conditions (e.g., pH and salt concentrations). This instability has prevented their further development in applications requiring intravenous administration. To mitigate this colloidal instability, this research explored Zein nanoparticles (NP)s that were modified with polyethylene glycol (PEG) either through functionalized PEG pre- or post-NP formation. The results suggest that the pre-functionalization of the Zein using N-hydroxysuccinimide ester terminated PEG is the method of choice for synthesizing Zein NPs with conjugated PEG (Zein:PEG-Zein NPs). Zein:PEG-Zein NPs formed using this method displayed excellent stability in physiologically relevant conditions over 72 h and were stable at 4 °C for at least 3 months. When the NPs were cultured with cells for 72 h, no cytotoxicity or early signs of apoptosis were identified. Cellular uptake of the Zein:PEG-Zein NPs did not seem to be impacted by the amount of PEG incorporated in the NP but were concentration-, time-, and temperature-dependent. The lowest percent, stable Zein:PEG-Zein NP formulation (80% unmodified Zein and 20% PEG-modified Zein) induced no observable toxicity over 14 days in CD-1 mice dosed at 70 mg/kg via the tail vein. However, repeat dose pharmacokinetic (PK) studies demonstrated that following the first dose, the second dose caused health issues that required euthanasia shortly after administration. For those animals that survived, there was faster plasma elimination of the Zein:PEG-Zein NPs. Despite this, the Zein:PEG-Zein NPs represent a significantly improved formulation approach, one that displays a long circulation half-life and is suitable for single-use administration. Repeat dose applications will require additional methods to silence the immune response that is generated when using these NPs intravenously.

RESUMO

BACKGROUND: Web-based patient education materials (PEMs) are frequently written above the recommended reading level in North America. Poor PEM readability limits the accessibility of medical information for individuals with average literacy levels or lower. Pediatric hospital and association websites have not only been shown to be a preferred source of information among caregivers but have also become a necessity during the COVID-19 pandemic. The readability of Canadian pediatric association websites has not yet been assessed. OBJECTIVE: The aim of this study is to determine if the content of PEMs from Canadian pediatric associations is written at a reading level that the majority of Canadians can understand. METHODS: A total of 258 PEMs were extracted from 10 Canadian pediatric associations and evaluated for their reading level using 10 validated readability scales. The PEMs underwent a difficult word analysis and comparisons between PEMs from different associations were conducted. RESULTS: Web-based PEMs were identified from 3 pediatric association websites, where the reading level (calculated as a grade level) was found to be an average of 8.8 (SD 1.8) for the Caring for Kids website, 9.5 (SD 2.2) for the Pediatric Endocrine Group website, and 13.1 (SD 2.1) for the Atlantic Pediatric Society website. The difficult word analysis identified that 19.9% (SD 6.6%) of words were unfamiliar, with 13.3% (SD 5.3%) and 31.9% (SD 6.1%) of words being considered complex (≥3 syllables) and long (≥6 letters), respectively. CONCLUSIONS: The web-based PEMs were found to be written above the recommended seventh-grade reading level for Canadians. Consideration should be made to create PEMs at an appropriate reading level for both patients and their caregivers to encourage health literacy and ultimately promote preventative health behaviors and improve child health outcomes.

RESUMO

Patient education materials (PEMs) were assessed from chronic health condition associations to determine their quality and if they were above the 6th grade reading level (GRL) recommended by the Centers for Disease Control and National Institutes of Health. PEMs from 55 associations were assessed for their GRL using ten readability scales and underwent a difficult word analysis. The associations had their quality assessed using two methods: the Journal of the American Medical Association (JAMA) Benchmarks and Health on the Net Foundation Code of Conduct certification (HONCode). Two thousand five hundred and ninety PEMs, collected between June and November 2021, were analyzed. The overall GRL average was 10.8 ± 2.8, with a range of 0 to 19. Difficult word analysis showed that 15.8% ± 4.8 contained complex words of 3 or more syllables and 25.7% ± 6.3 contained words which were unfamiliar. No association displayed all four indicators of quality according to JAMA Benchmarks or held an up-to-date HONCode certification. The PEM readability continues to be written at a level above the recommended GRL. Additionally, the lack of quality indicators from the associations' websites may make it difficult for older adults to identify the sources as credible. This represents an opportunity to optimize materials that would be understood by a wider audience.

RESUMO

Drug-delivery vehicles have been used extensively to modulate the biodistribution of drugs for the purpose of maximizing their therapeutic effects while minimizing systemic toxicity. The release characteristics of the vehicle must be balanced with its encapsulation properties to achieve optimal delivery of the drug. An alternative approach is to design a delivery vehicle that preferentially releases its contents under specific endogenous (e.g., tissue pH) or exogenous (e.g., applied temperature) stimuli. In the present manuscript, we report on a novel delivery system with potential for triggered release using external beam radiation. Our group evaluated Zein protein as the basis for the delivery vehicle and used radiation as the exogenous stimulus. Proteins are known to react with free radicals, produced during irradiation in aqueous suspensions, leading to aggregation, fragmentation, amino acid modification, and proteolytic susceptibility. Additionally, we incorporated gold particles into the Zein protein matrix to create hybrid Zein-gold nanoparticles (ZAuNPs). Zein-only nanoparticles (ZNPs) and ZAuNPs were subsequently exposed to kVp radiation (single dose ranging from 2 to 80 Gy; fractionated doses of 2 Gy delivered 10 times) and characterized before and after irradiation. Our data indicated that the presence of gold particles within Zein particles was correlated with significantly higher levels of alterations to the protein, and was associated with higher rates of release of the encapsulated drug compound, Irinotecan. The aggregate results demonstrated a proof-of-principle that radiation can be used with gold nanoparticles to modulate the release rates of protein-based drug-delivery vehicles, such as ZNPs.

RESUMO

The 2019 novel coronavirus (COVID-19) pandemic has prompted the reorganization in the scheduling and method of care for many patients, including patients diagnosed with cancer. Cancer patients, who have an immunocompromised status, may be at a higher risk of severe symptoms from infection with COVID-19. While information is rapidly evolving regarding COVID-19, Canada, both nationally and provincially, has been conveying new information to patients online. We assessed the content and readability of COVID-19-related online Canadian patient education material (PEM) for cancer patients to determine if the content of the material was written at a grade reading level that the majority of Canadians can understand. PEMs were extracted from provincial cancer agencies and the national Canadian Cancer Society, evaluated using 10 readability scales, qualitatively analyzed to identify their themes and difficult word content. Thirty-eight PEMs from both national and provincial cancers associations were, on average, written above the recommended 7th grade level. Each of the associations' average grade levels were: BC Cancer (11.00 95% confidence interval [CI] 8.27-13.38), CancerControl Alberta (10.46 95% CI 8.29-12.62), Saskatchewan Cancer Agency (11.08 95% CI 9.37-12.80), Cancer Care Manitoba (9.55 95% CI 6.02-13.01), Cancer Care Ontario (9.35 95% CI 6.80-11.90), Cancer Care Nova Scotia (10.95 95% CI 9.86-12.04), Cancer Care Eastern Health Newfoundland and Labrador (10.14 95% CI 6.87-13.41), and the Canadian Cancer Society (10.06 95% CI 8.07-12.05). Thematic analysis identified 4 themes: public health strategy, information about COVID-19, patient instructions during COVID-19, and resources. Fifty-three percent of the complex words identified were medical jargon. This represents an opportunity to improve PEM readability, to allow for greater comprehension amongst a wider target audience.

RESUMO

INTRODUCTION: Health literacy is an individual's ability to access, understand, and utilize information in order to create an informed decision regarding their health. Readability plays an integral role in health literacy as complex health information may be inaccessible to those with low health literacy. The aim of this study is to determine the readability of Canadian patient education material (PEM) for oncology related pharmaceutics. METHODS: Eighty PEMs from Cancer Care Ontario (CCO) and BC Cancer (BCC) were evaluated for their reading level using a Ford, Caylor, Sticht (FORCAST) analysis. Twenty therapies were then randomly selected and converted to plain text to be analyzed further using the Flesch-Kincaid Grade Level (FKGL), the Simple Measure of Gobbledygook (SMOG) Index, the Coleman-Liau Index (CLI), and the Gunning Fog Index (GFI). RESULTS: Both PEMs from CCO and BCC were above the recommended reading level with PEMs from CCO, on average, requiring a higher reading level. Within the text, the section which describes side effects was found to be the most complex section of the representative PEMs from BCC. PEMs from BCC which described antibody-based therapies were, on average, more difficult to read than small molecule-based therapies regardless from which section the PEM was being analyzed. These observations were not seen in CCO PEMs. CONCLUSIONS: Overall, online PEMs from major Canadian cancers associations were written above the recommended reading level. Consideration should be given to revision of these materials, with emphasis on the therapies' side effects, to allow for greater comprehension amongst a wider target audience.

RESUMO

BACKGROUND/OBJECTIVES: An increasing number of patients are using the internet to supplement information provided by medical professionals. Online geriatric patient education materials (PEMs) should be written at or below a 6th grade reading level (GRL) that takes into account barriers unique to the geriatric population. The objectives of the study are to assess PEMs of geriatric associations' websites and determine whether they are above the GRL recommended by the Centers for Disease Control and National Institutes of Health. DESIGN: Descriptive and correlational methodology. PEMs from 10 major geriatric associations were assessed for their GRL using 10 scales. Eight of the scales provide a numerical GRL while two of the scales provide a visual representation of the GRLs. Analysis was conducted using Readability Studio 2019.3. SETTING: Analysis was conducted February 2020. PARTICIPANTS: Identified 10 geriatric associations and 884 PEMs. MEASUREMENTS: GRLs were measured by 10 validated readability indices: the Degrees of Reading Power and Grade Equivalent test, Flesch-Kincaid grade level, Simple Measure of Gobbledygook test, Coleman-Liau Index, Gunning Fog Index, New Fog Count, New Dale-Chall readability formula, Ford, Caylor, Sticht scale, Raygor readability estimate graph, and Fry readability graph. RESULTS: The mean of all PEMs using the numerical scales was 11.1 ± 2.4. Ninety-nine percent of PEMs are above the 6th GRL. PEMs ranged from a grade 3.0 to 19.0 reading level. Analysis of variance demonstrated a significant difference between associations (P < .0001), and multiple comparison analysis identified the National Institute on Aging as the content easiest to read (9.5 ± 1.6). CONCLUSION: PEMs from geriatric association websites are written above the recommended 6th GRL. As patients increasingly look toward online supplementary health information during COVID-19, there is an opportunity for improving PEMs to enable greater comprehension by the target population.

RESUMO

This review explores the use of energy sources, including ultrasound, magnetic fields, and external beam radiation, to trigger the delivery of drugs from liposomes in a tumor in a spatially-specific manner. Each section explores the mechanism(s) of drug release that can be achieved using liposomes in conjunction with the external trigger. Subsequently, the treatment's formulation factors are discussed, highlighting the parameters of both the therapy and the medical device. Additionally, the pre-clinical and clinical trials of each triggered release method are explored. Lastly, the advantages and disadvantages, as well as the feasibility and future outlook of each triggered release method, are discussed.

RESUMO

Mercury is a highly toxic heavy metal and many DNA-based biosensors have been recently developed for Hg(2+) detection in water. Among them, thymine-rich DNA is the most commonly used for designing Hg(2+) sensors. However, the thymine-Hg(2+) interaction is strongly affected by the buffer conditions. We recently reported a molecular beacon containing phosphorothioate (PS)-modified RNA linkages that can be cleaved by Hg(2+). In this work, the fluorescence quenching and DNA adsorption properties of nano-sized graphene oxide (NGO) were used to develop a new sensor using the PS-RNA chemistry. Three DNA probes, containing one, three and five PS-RNA linkages, respectively, were tested. Finally, a fluorophore-labeled poly-A DNA with five PS-RNA linkages was selected and adsorbed by NGO. In the presence of Hg(2+), the fluorophore was released from NGO due to the cleavage reaction, resulting in a fluorescence enhancement. This sensor is highly selective for Hg(2+) with a detection limit of 8.5 nM Hg(2+). For comparison, a fluorophore-labeled poly-T DNA was also tested, which responded to Hg(2+) more slowly and was inhibited by high NaCl concentrations, while the PS-RNA probe was more tolerant to different buffer conditions. This work indicates a new method for interfacing DNA with NGO for Hg(2+) detection.
