"I'm in My Feelings Now": Examination of Advance Care Planning Video Declarations by People with Advanced Cancer from a Safety Net Hospital.

Background: Advance care planning (ACP) is underutilized among those with advanced cancer, leading to the potential of not receiving goal-concordant care. Objectives: To understand the experience of patients in creating a video declaration (ViDec) of their ACP preferences and their family member/caregivers' perceptions after viewing their ViDec. Design: Qualitative study among patients and family members/caregivers. Setting/Subjects: Patients were recruited from a large safety net hospital in the United States. Patients with any type of advanced cancer were enrolled to create a ViDec and participate in an individual interview. Patients also identified a family member/caregiver to participate. Measurements: Content and perceptions of usefulness of ViDecs among patients and family members/caregivers. Results: In total, 32 patients participated. Patients had a mean age of 61 (10) years, 15 (47%) were women, 14 (44%) were Black or African American, and 12 (37%) had a high school education or less; 25 family members/caregivers participated. Across all ViDecs, the most common theme pertained to ACP for preferred medical treatments (97%). We describe three case studies of patient and caregiver pairs to represent salient dimensions of our data: (1) high perceived usefulness of ViDec, (2) populations at risk for not receiving goal-concordant care, and (3) varied responses to ViDec among family members/caregivers. Recommendations to improve the ViDec process included providing structured prompts to patients. Conclusions: These case studies highlight the potential high-perceived usefulness of ViDecs across patients and caregivers. ViDecs have the potential to improve care among patients with advanced cancer.

Shifting sensitivity of septoria tritici blotch compromises field performance and yield of main fungicides in Europe.

Septoria tritici blotch (STB; Zymoseptoria tritici) is a severe leaf disease on wheat in Northern Europe. Fungicide resistance in the populations of Z. tritici is increasingly challenging future control options. Twenty-five field trials were carried out in nine countries across Europe from 2019 to 2021 to investigate the efficacy of specific DMI and SDHI fungicides against STB. During the test period, two single DMIs (prothioconazole and mefentrifluconazole) and four different SDHIs (fluxapyroxad, bixafen, benzovindiflupyr and fluopyram) along with different co-formulations of DMIs and SDHIs applied at flag leaf emergence were tested. Across all countries, significant differences in azole performances against STB were seen; prothioconazole was outperformed in all countries by mefentrifluconazole. The effects also varied substantially between the SDHIs, with fluxapyroxad providing the best efficacy overall, while the performance of fluopyram was inferior to other SDHIs. In Ireland and the UK, the efficacy of SDHIs was significantly lower compared with results from continental Europe. This reduction in performances from both DMIs and SDHIs was reflected in yield responses and also linked to decreased sensitivity of Z. tritici isolates measured as EC50 values. A clear and significant gradient in EC50 values was seen across Europe. The lower sensitivity to SDHIs in Ireland and the UK was coincident with the prevalence of SDH-C-alterations T79N, N86S, and sporadically of H152R. The isolates' sensitivity to SDHIs showed a clear cross-resistance between fluxapyroxad, bixafen, benzovindiflupyr and fluopyram, although the links with the latter were less apparent. Co-formulations of DMIs + SDHIs performed well in all trials conducted in 2021. Only minor differences were seen between fluxapyroxad + mefentrifluconazole and bixafen + fluopyram + prothioconazole; the combination of benzovindiflupyr + prothioconazole gave an inferior performance at some sites. Fenpicoxamid performed in line with the most effective co-formulations. This investigation shows a clear link between reduced field efficacy by solo SDHIs as a result of increasing problems with sensitivity shifting and the selection of several SDH-C mutations. The presented data stress the need to practice anti-resistance strategies to delay further erosion of fungicide efficacy.

A National Survey on Patient Provider Agreements When Prescribing Opioids for Chronic Pain.

BACKGROUND: Many national guidelines recommend the use of patient provider agreements (PPAs) when prescribing opioids for chronic pain. There are no standards for PPA content, readability, or administration processes. OBJECTIVE: Conduct a national survey of providers who use PPAs to describe the process of administering them, assess views on their utility, and obtain PPAs to evaluate thematic content and readability. DESIGN: Cross-sectional electronic survey and request for PPAs. PARTICIPANTS: Registrants for the Safer/Competent Opioid Prescribing Education (SCOPE of Pain) Program between March 2013 and June 2017. MAIN MEASURES: Respondents' reports on how PPAs are administered and views on their usefulness. A sample of PPAs assessed for themes and readability. KEY RESULTS: Using a convenience sample of 62,530 SCOPE of Pain registrants, we obtained a cohort of 430 individuals from 43 states who use PPAs. The majority of respondents worked in primary care (64%) and pain (18%) specialties. Reviewing PPAs with patients was primarily done by prescribers (80%), and the average perceived time to administer PPAs was 13 min. Although 66% of respondents thought PPAs were "often" or "always" worth the effort, only 28% considered them "often" or "always" effective in reducing opioid misuse. The PPA reading burden surpassed recommended patient education standards, with only 2.5% at or below fifth-grade reading level. PPAs focused more on rules and consequences of patients' non-compliance than on a shared treatment plan. CONCLUSIONS: Most respondents perceive patient provider agreements (PPAs) as time-consuming and minimally effective in reducing opioid misuse yet still view them as valuable. PPAs are written far above recommended reading levels and serve primarily to convey consequences of non-compliance. Because PPAs are recommended by national safer opioid prescribing guidelines as a risk mitigation strategy, it would be beneficial to develop a standard PPA and study its effectiveness.

Health Literacy Mediates Racial Disparities in Cardiopulmonary Resuscitation Knowledge among Chronic Kidney Disease Patients.

Black patients with chronic kidney disease (CKD) receive more cardiopulmonary resuscitation (CPR) than other racial groups, and knowledge of CPR influences preferences for care. As limited health literacy disproportionately affects Blacks and contributes to disparities in end-of-life (EOL) care, we investigated whether health literacy mediates racial disparities in CPR knowledge. Black and White adult patients with advanced CKD completed CPR knowledge surveys. Health literacy was assessed using the Rapid Estimate of Adult Literacy in Medicine. Among 149 patients, Black patients were more likely to have limited health literacy and lower mean CPR knowledge scores than White patients. In adjusted analyses, health literacy mediated racial differences in CPR knowledge. Knowledge of CPR is lower among Black compared with White CKD patients and health literacy is a mediator of this difference. Future CPR educational interventions should target health literacy barriers to improve informed decision-making and decrease racial disparities at the end of life.

"It's like a mirror image of my illness": Exploring Patient Perceptions About Illness Using Health Mind Mapping-a Qualitative Study.

BACKGROUND: A patient's self-management of chronic disease is influenced in part by their explanatory model of illness (EMI) and daily lived experiences (DLE). Unfortunately, assessing patient's EMI and using this information to engage patients in chronic illness self-management continues to be a challenge. OBJECTIVE: "Health mind mapping" (HMM) is a novel process that captures a patient's EMI and DLE through the use of a graphic representation of ideas. We aimed to explore patient's experiences using HMM. DESIGN: Qualitative study utilizing semi-structured interviews. PARTICIPANTS: Adult patients with uncontrolled type 2 diabetes from a primary care clinic. APPROACH: A facilitator guided 20 participants through the process of developing a health mind map. Subsequently, each participant completed a semi-structured interview about their experience with the process and perceptions about how their maps could be used. The process and interviews were video and audio recorded. We conducted a content analysis of the maps and a thematic analysis, using an inductive approach, of the interview data. RESULTS: Participants explored a wide range of EMs and DLEs in their HMM process. Participants reported that the HMM process (1) helped to develop insight about self and illness; (2) was a catalyst for wanting to take actions to improve illness; and (3) represented an opportunity to actively share illness experiences. They reported potential uses of the map: (1) to communicate about their illness to others in their social network; (2) to communicate about their illness to providers; (3) to help others with diabetes manage their illness; and (4) to encourage ongoing engagement in diabetes self-care. CONCLUSIONS: Participants reported that HMM helped them develop new insight about their illness and was a catalyst for encouraging them to take control of their illness. HMM has the potential to facilitate communication with providers and engage patients in collaborative goal setting to improve self-care in chronic illness.

Feasibility and Patient Perceptions of Video Declarations Regarding End-of-Life Decisions by Hospitalized Patients.

BACKGROUND: A videotaped declaration by patients of their advance care planning preferences could be an opportunity to supplement advance directive forms and be a source of information for family, caregivers, and clinicians, yet research is needed to examine the content and acceptability of making declarations among patients. OBJECTIVE: To evaluate the content and acceptability of 'video declarations': the process of patients videotaping themselves describing their advance care planning preferences. DESIGN: We showed a brief video describing three approaches to end-of-life care and then invited participants to use an iPad to videotape themselves making a declaration about their wishes. SETTING/SUBJECTS: Hospitalized patients from a large urban U.S. safety net hospital. MEASUREMENTS: We interviewed participants about the acceptability of the declaration process. Declarations were transcribed and coded by a team, with multiple stakeholder input. RESULTS: There were 16 participants; mean age was 60 (SD = 14) years. One participant declined. Out of 15 declarations, most were able to express their wishes for CPR (n = 12) and intubation (n = 13). Participants frequently discussed their family structure (n = 11), religious/spiritual well-being (n = 8), legacy/dignity issues (n = 6), and physical symptoms (n = 6). Nine declarations had directives judged to be unclear. The majority (66%) thought that this process was quite a bit or extremely helpful. CONCLUSIONS: Findings show that asking hospitalized patients to make videos describing their advance care planning preferences was feasible and acceptable. While the majority described their wishes around CPR and intubation, a fair amount of uncertainty remained. Further research is needed to support patients in describing their wishes clearly and test the effectiveness of video declarations to promote care concordant with preferences.

Sociodemographic Factors Mediate Race and Ethnicity-associated Childhood Asthma Health Disparities: a Longitudinal Analysis.

BACKGROUND: Race and ethnicity-based disparities in childhood asthma are well established. We characterized the longitudinal effects associated with being African-American/Black or Hispanic/Latino on a range of asthma outcomes, and the extent to which sociodemographic factors, caregiver health literacy, education level, and asthma knowledge mediate these associations. METHODS: Children ages 8-15 and their caregivers (n = 544) in the Chicago Initiative to Raise Asthma Health Equity (CHIRAH) cohort completed interviews every 3 months for 1.5 years. Health literacy was measured with the Rapid Estimate of Adult Literacy in Medicine (REALM). Other covariates include sex, age, education level, income, smoke exposure, asthma duration, employment status, and insurance status. We conducted a series of models to evaluate these factors as mediators of the relationship between race/ethnicity and (1) asthma knowledge, (2) asthma-related quality of life, (3) asthma severity, and (4) asthma control based on NAEPP/EPR-3 2007 guidelines. RESULTS: African-American race and Hispanic/Latino ethnicity were significantly associated with all outcomes when compared to Whites. Adjusting for sociodemographic factors resulted in the most significant mediation of racial/ethnic disparities in all outcomes. Health literacy was a partial mediator of race/ethnic disparities in asthma knowledge and asthma-related quality of life. Asthma knowledge remained significantly associated with race and ethnicity, and race remained associated with asthma-related quality of life. CONCLUSIONS: African-American race and Hispanic/Latino ethnicity are significantly associated with worse asthma compared to Whites in longitudinal analyses. Sociodemographic factors are potent mediators of these disparities, and should be considered when designing interventions to reduce asthma disparities. Health literacy and education level are partial mediators.

Health Literacy and Education as Mediators of Racial Disparities in Patient Activation Within an Elderly Patient Cohort.

The Patient Activation Measure (PAM) assesses facets of patient engagement to identify proactive health behaviors and is an important predictor of health outcomes. Health literacy and education are also important for patient participation and successful navigation of the health care system. Because health literacy, education, and patient activation are associated with racial disparities, we sought to investigate whether health literacy and education would mediate racial differences in patient activation. Participants were 265 older adults who participated in a computer-based exercise interventional study. Health literacy was assessed using the Test of Functional Health Literacy in Adults (TOFHLA). Of 210 eligible participants, 72% self-identified as Black and 28% as White. In adjusted analyses, education and health literacy each significantly reduced racial differences in patient activation. These findings are especially important when considering emerging data on the significance of patient activation and new strategies to increase patient engagement.

Racial Disparities in End-of-Life Communication and Preferences among Chronic Kidney Disease Patients.

BACKGROUND: Previous studies on end-of-life (EOL) care among patients with chronic kidney disease (CKD) have been largely limited to White hemodialysis patients. In this study, we sought to explore racial variability in EOL communication, care preferences and advance care planning (ACP) among patients with advanced CKD prior to decisions regarding the initiation of dialysis. METHODS: We performed a cross-sectional study between 2013 and 2015 of Black and White patients with stage IV or V CKD (per the Modified Diet in Renal Disease estimation of GFR <30 ml/min/1.73 m2) from 2 academic centers in Boston. We assessed experiences with EOL communication, ACP, EOL care preferences, hospice knowledge, spiritual/religious and cultural beliefs, and distrust of providers. RESULTS: Among 152 participants, 41% were Black. Black patients were younger, had less education, and lower income than White patients (all p < 0.01). Black patients also had less knowledge of hospice compared to White patients (17 vs. 61%, p < 0.01). A small fraction of patients (8%) reported having EOL discussions with their nephrologists and the majority had no advance directives. In multivariable analyses, Blacks were more likely to have not communicated EOL preferences (adjusted OR 2.70, 95% CI 1.08-6.76) and more likely to prefer life-extending treatments (adjusted OR 3.06, 95% CI 1.23-7.60) versus Whites. CONCLUSIONS: As Black and White patients with advanced CKD differ in areas of EOL communication, preferences, and hospice knowledge, future efforts should aim to improve patient understanding and promote informed decision-making.

Disparities in Age-Associated Cognitive Decline Between African-American and Caucasian Populations: The Roles of Health Literacy and Education.

OBJECTIVES: To examine health literacy as a mediator of racial disparities in cognitive decline as measured by executive function in elderly adults. DESIGN: Prospective cohort study. SETTING: Secondary analysis of ElderWalk trial in Boston, Massachusetts. PARTICIPANTS: English-speaking African-American and Caucasian individuals in a walking intervention for community-dwelling adults aged 65 and older without dementia at baseline who completed baseline and 12-month evaluations (N = 198). MEASUREMENTS: Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Fluid and crystallized cognitive functions were measured at baseline and 12 months using the Trail-Making Test Part B minus Part B (TMT B-A) and the Controlled Oral Word Association Test (COWAT). Associations between health literacy and 12-month cognitive decline were modeled using multivariate linear regression. RESULTS: Participants with higher health literacy and education experienced less cognitive decline than those with limited health literacy according to the TMT B-A (P = .01). After adjusting for covariates, Caucasian participants (n = 63) experienced less decline than African-American participants (n = 135) on TMT B-A (P = .001) and COWAT (P = .001). Adjusting for health literacy led to a 25.3% decrease in the point estimate for racial difference in TMT B-A and a 19.5% decrease in COWAT. Although independently related to cognitive decline, educational attainment did not mediate racial differences. CONCLUSION: Health literacy is a partial mediator of racial disparities in cognitive decline. These results indicate the need to develop interventions to mitigate cognitive decline that individuals with low heath literacy can use and to modify the healthcare environment to better accommodate this population.

Racial disparities in patient activation: Evaluating the mediating role of health literacy with path analyses.

OBJECTIVE: The aim of this study was to use path analysis methods to determine if health literacy mediates the relationship between race and patient activation. METHODS: We performed a secondary analysis of data from a randomized controlled trial in elderly, urban, minority patients using path analysis. Path analysis was used to evaluate the mediation of race on patient activation through different variables. Several models were tested for best fit for their effects on patient activation. RESULTS: Across all models, significant mediation paths were identified from race to lower patient activation through health literacy. This relationship remained significant throughout alternative model testing for covariate combinations. The best-fit model included an indirect effect of sex on patient activation through health literacy indicating that the mediation effect of health literacy on patient activation was most profound for African American males. Health literacy had a bigger influence on patient activation for participants with a greater comorbidity than for those with fewer conditions. No significant direct effect was shown between race and patient activation in any of the models. CONCLUSION: Racial disparities in patient activation were fully mediated by health literacy skills. PRACTICE IMPLICATIONS: Future interventions to improve racial disparities in patient activation need to be targeted at improving health literacy.

Microtubule disruption synergizes with oncolytic virotherapy by inhibiting interferon translation and potentiating bystander killing.

In this study, we show that several microtubule-destabilizing agents used for decades for treatment of cancer and other diseases also sensitize cancer cells to oncolytic rhabdoviruses and improve therapeutic outcomes in resistant murine cancer models. Drug-induced microtubule destabilization leads to superior viral spread in cancer cells by disrupting type I IFN mRNA translation, leading to decreased IFN protein expression and secretion. Furthermore, microtubule-destabilizing agents specifically promote cancer cell death following stimulation by a subset of infection-induced cytokines, thereby increasing viral bystander effects. This study reveals a previously unappreciated role for microtubule structures in the regulation of the innate cellular antiviral response and demonstrates that unexpected combinations of approved chemotherapeutics and biological agents can lead to improved therapeutic outcomes.

Development and validation of the comprehensive health activities scale: a new approach to health literacy measurement.

Current health literacy measures have been criticized for solely measuring reading and numeracy skills when a broader set of skills is necessary for making informed health decisions, especially when information is often conveyed verbally and through multimedia video. The authors devised 9 health tasks and a corresponding 190-item assessment to more comprehensively measure health literacy skills. A sample of 826 participants between the ages of 55 and 74 years who were recruited from an academic general internal medicine practice and three federally qualified health centers in Chicago, Illinois, completed the assessment. Items were reduced using hierarchical factor analysis and item response theory resulting in the 45-item Comprehensive Health Activities Scale. All 45 items loaded on 1 general latent trait, and the resulting scale demonstrated high reliability and strong construct validity using measures of health literacy and global cognitive functioning. The predictive validity of the Comprehensive Health Activities Scale using self-reported general, physical, and mental health status was comparable to or better than widely used measures of health literacy, depending on the outcome. Despite comprehensively measuring health literacy skills, items in the Comprehensive Health Activities Scale supported 1 primary construct. With similar psychometric properties, current measures may be adequate, depending on the purpose of the assessment.

Literacy and race as risk factors for low rates of advance directives in older adults.

OBJECTIVES: To examine the effect of the relationship between literacy and other individual-level factors on having an advance directive (AD). DESIGN: Face-to-face structured interview. SETTING: Participants were recruited from an academic general internal medicine clinic and one of four federally qualified health centers in Chicago. PARTICIPANTS: Seven hundred eighty-four adults aged 55 to 74. MEASUREMENTS: Assessment of participant literacy, sociodemographic factors, and having an AD for medical care. RESULTS: One-eighth (12.4%) of participants with low literacy, 26.6% of those with marginal literacy, and 49.5% of those with adequate literacy reported having an AD (P < .001). In multivariable analyses, literacy and race were independently associated with less likelihood of having an AD. Specifically, participants with limited literacy (risk ratio (RR) = 0.45, 95% confidence interval (CI) = 0.22-0.95) and African Americans (RR = 0.64, 95% CI = 0.47-0.88) were less likely to have an AD. Exploratory analyses showed that there was not a significant interaction between the effect of literacy and race. CONCLUSION: Limited literacy and African-American race were significant risk factors for not having an AD in this cohort of older adults. Literacy and race probably represent two separate but important causal pathways that need to be understood to improve how the healthcare system ascertains and protects individuals' advance care preferences.

Comparative analysis of print and multimedia health materials: a review of the literature.

OBJECTIVE: Evaluate the evidence regarding the relative effectiveness of multimedia and print as modes of dissemination for patient education materials; examine whether development of these materials addressed health literacy. METHODS: A structured literature review utilizing Medline, PsycInfo, and the Cumulative Index to the Nursing and Allied Health Literature (CINAHL), supplemented by reference mining. RESULTS: Of 738 studies screened, 30 effectively compared multimedia and print materials. Studies offered 56 opportunities for assessing the effect of medium on various outcomes (e.g., knowledge). In 30 instances (54%), no difference was noted between multimedia and print in terms of patient outcomes. Multimedia led to better outcomes vs. print in 21 (38%) comparisons vs. 5 (9%) instances for print. Regarding material development, 12 studies (40%) assessed readability and 5 (17%) involved patients in tool development. CONCLUSIONS: Multimedia appears to be a promising medium for patient education; however, the majority of studies found that print and multimedia performed equally well in practice. Few studies involved patients in material development, and less than half assessed the readability of materials. PRACTICE IMPLICATIONS: Future research should focus on comparing message-equivalent tools and assessing their effect on behavioral outcomes. Material development should include explicit attention to readability and patient input.

Literacy, cognitive function, and health: results of the LitCog study.

BACKGROUND: Emerging evidence suggests the relationship between health literacy and health outcomes could be explained by cognitive abilities. OBJECTIVE: To investigate to what degree cognitive skills explain associations between health literacy, performance on common health tasks, and functional health status. DESIGN: Two face-to-face, structured interviews spaced a week apart with three health literacy assessments and a comprehensive cognitive battery measuring 'fluid' abilities necessary to learn and apply new information, and 'crystallized' abilities such as background knowledge. SETTING: An academic general internal medicine practice and three federally qualified health centers in Chicago, Illinois. PATIENTS: Eight hundred and eighty-two English-speaking adults ages 55 to 74. MEASUREMENTS: Health literacy was measured using the Rapid Estimate of Adult Literacy in Medicine (REALM), Test of Functional Health Literacy in Adults (TOFHLA), and Newest Vital Sign (NVS). Performance on common health tasks were globally assessed and categorized as 1) comprehending print information, 2) recalling spoken information, 3) recalling multimedia information, 4) dosing and organizing medication, and 5) healthcare problem-solving. RESULTS: Health literacy measures were strongly correlated with fluid and crystallized cognitive abilities (range: r=0.57 to 0.77, all p<0.001). Lower health literacy and weaker fluid and crystallized abilities were associated with poorer performance on healthcare tasks. In multivariable analyses, the association between health literacy and task performance was substantially reduced once fluid and crystallized cognitive abilities were entered into models (without cognitive abilities: ß= -28.9, 95 % Confidence Interval (CI) -31.4 to -26.4, p; with cognitive abilities: ß= -8.5, 95 % CI -10.9 to -6.0). LIMITATIONS: Cross-sectional analyses, English-speaking, older adults only. CONCLUSIONS: The most common measures used in health literacy studies are detecting individual differences in cognitive abilities, which may predict one's capacity to engage in self-care and achieve desirable health outcomes. Future interventions should respond to all of the cognitive demands patients face in managing health, beyond reading and numeracy.

What did the doctor say? Health literacy and recall of medical instructions.

BACKGROUND: Limited literacy has repeatedly been linked to problems comprehending health information, although the majority of studies to date have focused on reading various print health materials. We sought to investigate patients' ability to recall spoken medical instructions in the context of a hypothetical clinical encounter, and whether limited health literacy would adversely affect performance on the task. METHODS: A total of 755 patients aged 55 to 74 were recruited from 1 academic internal medicine clinic and 3 federally qualified health centers. Participants' health literacy skills and recall of spoken medical instructions for 2 standard hypothetical video scenarios [wound care, gastroesophageal reflux disease (GERD) diagnosis] were assessed. RESULTS: The majority (71.6%) of participants had adequate health literacy skills, and these individuals performed significantly better in correctly recalling spoken information than those with marginal and low literacy in both scenarios: [wound care-mean (SD): low 2.5 (1.3) vs. marginal 3.5 (1.3) vs. adequate 4.6 (1.1); P<0.001), GERD: low 4.2(1.7) vs. marginal 5.2 (1.7) vs. adequate 6.5 (1.7); P<0.001]. Regardless of literacy level, overall recall of information was poor. Few recognized pain (28.5%) or fever (28.2%) as signs of infection. Only 40.5% of participants correctly recalled when to take their GERD pills. CONCLUSIONS: Many older adults may have difficulty remembering verbal instructions conveyed during clinical encounters. We found those with lower health literacy to have poorer ability to recall information. Greater provider awareness of the impact of low health literacy on the recall of spoken instructions may guide providers to communicate more effectively and employ strategies to confirm patient understanding.

Factors associated with patient understanding of preeclampsia.

OBJECTIVE: To explore the extent to which pregnant women understand the symptoms and potential complications related to preeclampsia and to determine the factors that are associated with better understanding. METHODS: This was a cross-sectional study in which 112 pregnant patients were interviewed to determine their preeclampsia knowledge. Knowledge was evaluated using a 25-item survey addressing the symptoms, consequences, and proper patient actions associated with preeclampsia. Patients were also asked in an open-ended question to define preeclampsia; all responses were rated by three obstetricians. Information about demographics, medical and obstetrical history, and health literacy was also obtained. Health literacy was assessed using the short Test of Functional Health Literacy in Adults (S-TOFHLA). RESULTS: Patients correctly answered only 43% of the 25 questions assessing preeclampsia knowledge. Moreover, only 14% of the patients were able to provide a definition that correctly reflected the syndrome. Factors associated with a greater proportion of correct answers on the questionnaire were higher literacy, multiparity, history of preeclampsia, and receipt of information about preeclampsia from a clinician or another information source (e.g., the Internet, television, a book, or a friend). CONCLUSIONS: Pregnant patients have a generally poor understanding of preeclampsia, although improved understanding is associated with having received information about the disease. Further investigation will be needed to determine how best to educate patients and whether this education can also decrease adverse outcomes associated with this syndrome.

Helping patients simplify and safely use complex prescription regimens.

BACKGROUND: There is considerable variability in the manner in which prescriptions are written by physicians and transcribed by pharmacists, resulting in patient misunderstanding of label instructions. A universal medication schedule was recently proposed for standardizing prescribing practices to 4 daily time intervals, thereby helping patients simplify and safely use complex prescription regimens. We investigated whether patients consolidate their medications or whether there is evidence of unnecessary regimen complexity that would support standardization. METHODS: Structured interviews were conducted with 464 adults (age range, 55-74 years) who were receiving care either at an academic general medicine practice or at 1 of 3 federally qualified health centers in Chicago, Illinois. Participants were given a hypothetical, 7-drug medication regimen and asked to demonstrate how and when they would take all of the medications in a 24-hour period. The regimen could be consolidated into 4 dosing episodes per day. The primary outcome was the number of times per day that individuals would take medication. Root causes for patients complicating the regimen (>4 times a day) were examined. RESULTS: Participants on average identified 6 times (SD, 1.8 times; range, 3-14 times) in 24 hours to take the 7 drugs. One-third of the participants (29.3%) dosed their medications 7 or more times per day, while only 14.9% organized the regimen into 4 or fewer times a day. In multivariable analysis, low literacy was an independent predictor of more times per day for dosing the regimen (ß = 0.67; 95% confidence interval, 0.12-1.22; P = .02). Instructions for 2 of the drugs were identical, yet 31.0% of the participants did not take these medications at the same time. Another set of drugs had similar instructions, with the primary exception of 1 drug having the added instruction to take "with food and water." Half of the participants (49.5%) took these medications at different times. When the medications had variable expressions of the same dose frequency (eg, "every 12 hours" vs "twice daily"), 79.0% of the participants did not consolidate the medications. CONCLUSIONS: Many patients, especially those with limited literacy, do not consolidate prescription regimens in the most efficient manner, which could impede adherence. Standardized instructions proposed with the universal medication schedule and other task-centered strategies could potentially help patients routinely organize and take medication regimens.

A high-throughput pharmacoviral approach identifies novel oncolytic virus sensitizers.

Oncolytic viruses (OVs) are promising anticancer agents but like other cancer monotherapies, the genetic heterogeneity of human malignancies can lead to treatment resistance. We used a virus/cell-based assay to screen diverse chemical libraries to identify small molecules that could act in synergy with OVs to destroy tumor cells that resist viral infection. Several molecules were identified that aid in viral oncolysis, enhancing virus replication and spread as much as 1,000-fold in tumor cells. One of these molecules we named virus-sensitizers 1 (VSe1), was found to target tumor innate immune response and could enhance OV efficacy in animal tumor models and within primary human tumor explants while remaining benign to normal tissues. We believe this is the first example of a virus/cell-based "pharmacoviral" screen aimed to identify small molecules that modulate cellular response to virus infection and enhance oncolytic virotherapy.
