Patterns of dietary quality, physical activity, and sleep duration among cancer survivors and caregivers.

Fruit and vegetable intake (FVI), moderate-to-vigorous physical activity (MVPA), and sleep duration are each independently associated with cancer-related and general health outcomes among cancer survivors. Past research suggests that health behaviors cluster among cancer survivors, with caregivers demonstrating similar patterns. This analysis examined co-occurrence of FVI, MVPA, and sleep duration among cancer survivors and informal cancer caregivers and identified sociodemographic and clinical correlates of health behavior engagement. Using data from the Health Information National Trends Survey (HINTS), an exploratory latent profile analysis (LPA) was conducted among those self-reporting a history of cancer or identifying as a cancer caregiver. The LPA model was fit with daily self-reported FVI (cups/d), MPVA (minutes/d) and sleep duration (hours/d). Multinomial logistic regression models were used to predict profile membership based on sociodemographic and clinical characteristics. Four health behavior profiles were identified (Least Engaged-No MVPA, Least Engaged-Low MVPA, Moderately Engaged, and Highly Engaged). The largest profile membership was Least Engaged-No MVPA, capturing 37% of the sample. Profiles were most distinguished by MVPA, with the lowest variance in sleep duration. Participants reporting higher FVI also often reported greater MVPA and longer sleep duration. Profile membership was significantly associated with age, relationship status, education, income, rurality, alcohol use, self-efficacy, psychological distress, BMI, and cancer type. This study identified four health behaviors patterns and sociodemographic correlates that distinguished those patterns among cancer survivors and caregivers drawn from a nationally representative sample. Results may help identify for whom health behavior interventions could be of greatest benefit.

Children's Retrieval of Science Facts: The Role of Hints and Confidence.

The effortful process of retrieving information from memory has been established as an effective strategy for improving student learning. However, we have a limited understanding of the development of retrieval practice in children, including contexts that may scaffold its benefit. In the current pre-registered study, we examined whether the use of hints during retrieval practice improved free recall in an online science learning task in 8- to 13-years-olds (N = 77, Nfemales = 36). We found partial evidence supporting the provision of hints as boosting the benefit of retrieval practice. Children's long-term retention of science facts was higher when they received hints during an earlier practice test compared to restudying information, but not compared to a test only condition without hints. Furthermore, we found similar effects across both age and levels of confidence, suggesting that retrieval practice remains stable across these factors.

Consumption of Health-Related Videos and Human Papillomavirus Awareness: Cross-Sectional Analyses of a US National Survey and YouTube From the Urban-Rural Context.

BACKGROUND: Nearly 70% of Americans use the internet as their first source of information for health-related questions. Contemporary data on the consumption of web-based videos containing health information among American adults by urbanity or rurality is currently unavailable, and its link with health topic awareness, particularly for human papillomavirus (HPV), is not known. OBJECTIVE: We aim to describe trends and patterns in the consumption of health-related videos on social media from an urban-rural context, examine the association between exposure to health-related videos on social media and awareness of health topics (ie, HPV and HPV vaccine), and understand public interest in HPV-related video content through search terms and engagement analytics. METHODS: We conducted a cross-sectional analysis of the US Health Information National Trends Survey 6, a nationally representative survey that collects data from civilian, noninstitutionalized adults aged 18 years or older residing in the United States. Bivariable analyses were used to estimate the prevalence of consumption of health-related videos on social media among US adults overall and by urbanity or rurality. Multivariable logistic regression models were used to examine the association between the consumption of health-related videos and HPV awareness among urban and rural adults. To provide additional context on the public's interest in HPV-specific video content, we examined search volumes (quantitative) and related query searches (qualitative) for the terms "HPV" and "HPV vaccine" on YouTube. RESULTS: In 2022, 59.6% of US adults (152.3 million) consumed health-related videos on social media, an increase of nearly 100% from 2017 to 2022. Prevalence increased among adults living in both urban (from 31.4% in 2017 to 59.8% in 2022; P<.001) and rural (from 22.4% in 2017 to 58% in 2022; P<.001) regions. Within the urban and rural groups, consumption of health-related videos on social media was most prevalent among adults aged between 18 and 40 years and college graduates or higher-educated adults. Among both urban and rural groups, adults who consumed health-related videos had a significantly higher probability of being aware of HPV and the HPV vaccine compared with those who did not watch health videos on the internet. The term "HPV" was more frequently searched on YouTube compared with "HPV vaccine." Individuals were most commonly searching for videos that covered content about the HPV vaccine, HPV in males, and side effects of the HPV vaccine. CONCLUSIONS: The consumption of health-related videos on social media in the United States increased dramatically between 2017 and 2022. The rise was prominent among both urban and rural adults. Watching a health-related video on social media was associated with a greater probability of being aware of HPV and the HPV vaccine. Additional research on designing and developing social media strategies is needed to increase public awareness of health topics.

Associations of Wearable Activity Tracker Use With Physical Activity and Health Outcomes in Patients With Cancer: Findings from a Population-Based Survey Study.

BACKGROUND: Physical inactivity is a global issue for cancer survivors. Wearable activity trackers are promising to address physical inactivity by providing real-time feedback on physical activity and offering opportunities for self-monitoring and goal setting. Meta-analysis has reported the effects of interventions that incorporate wearable activity trackers on improved physical inactivity and related health outcomes (eg, BMI, anxiety and depression, and self-rated health status). However, wearable activity trackers were often used as an adjunct to physical activity interventions, and the effectiveness of wearable activity trackers alone is unknown. OBJECTIVE: This study aims to determine the association of wearable activity trackers with physical activity and health outcomes in patients with cancer. METHODS: Data from 957 cancer survivors from the Health Information National Trends Survey-Surveillance, Epidemiology, and End Results (HINTS-SEER) were analyzed. The outcome variables examined were time spent in moderate to vigorous physical activity, weekly frequency of strength training, BMI, anxiety and depression levels, and self-assessed health status. The primary independent variable was whether cancer survivors had used wearable activity trackers within the past 12 months. Design-based linear regression for continuous outcome variables and ordinal logistic regression for ordinal outcome variables were conducted to determine the associations after controlling for sociodemographic, cancer-related, and health-related factors. All data analyses accounted for the complex survey design and sample weights. RESULTS: Only 29% of cancer survivors reported wearable activity tracker use. Bivariate analyses showed that younger age (P<.001), higher education (P=.04), higher income (P<.001), and an employed status (P<.001) were significantly associated with wearable activity tracker use. Wearable activity tracker use was significantly associated with higher time spent in moderate to vigorous physical activity (adjusted =37.94, 95% CI 8.38-67.5; P=.01), more frequent strength training per week (adjusted odds ratio [OR] 1.50, 95% CI 1.09-2.06; P=.01), and better self-rated health status (adjusted OR 1.58, 95% CI 1.09-2.29; P=.01), but not with BMI or anxiety and depression. CONCLUSIONS: This study suggests that the uptake of wearable activity trackers is low and highlights the digital divide among patients with cancer. This study has confirmed the associations of wearable activity tracker use with physical activity and self-rated health, supporting using wearable activity trackers as a promising tool to facilitate physical activity promotion.

The acute vestibular syndrome: prevalence of new hearing loss and its diagnostic value.

OBJECTIVES: To assess the prevalence of new hearing losses in patients with acute vestibular syndrome (AVS) and to start to evaluate its diagnostic value for the differentiation between peripheral and central causes. DESIGN: We performed a cross-sectional prospective study in AVS patients presenting to our Emergency Department (ED) from February 2015 to November 2020. All patients received an MRI, Head-impulse test, Nystagmus test and Test of skew ('HINTS'), caloric testing and a pure-tone audiometry. RESULTS: We assessed 71 AVS patients, 17 of whom had a central and 54 a peripheral cause of dizziness. 12.7% had an objective hearing loss. 'HINTS' had an accuracy of 78.9% to diagnose stroke, whereas 'HINTS' plus audiometry 73.2%. 'HINTS' sensitivity was 82.4% and specificity 77.8% compared to 'HINTS' plus audiometry showing a sensitivity of 82.4% and specificity of 70.4%. The four patients with stroke and minor stroke had all central 'HINTS'. 55% of the patients did not perceive their new unilateral hearing loss. CONCLUSIONS: We found that almost one-eighth of the AVS patients had a new onset of hearing loss and only half had self-reported it. 'HINTS' plus audiometry proved to be less accurate to diagnose a central cause than 'HINTS' alone. Audiometry offered little diagnostic accuracy to detect strokes in the ED but might be useful to objectify a new hearing loss that was underestimated in the acute phase. Complete hearing loss should be considered a red flag, as three in four patients suffered from a central cause.

Distinguishing Peripheral from Central Causes of Dizziness and Vertigo without using HINTS or STANDING.

Three validated diagnostic algorithms for diagnosing patients with acute onset dizziness or vertigo (HINTS, HINTS-plus and STANDING) exist. All are extremely accurate in distinguishing peripheral from central causes of dizziness when done by experienced clinicians. However, uptake of these diagnostic tools in routine emergency medicine practice has been sub-optimal, in part, due to clinicians' unease with the head impulse test, the most useful component contained of these algorithms. Use of these validated algorithms is the best way to accurately diagnose patients with acute dizziness. For clinicians who are unfamiliar with or uncomfortable performing or interpreting HINTS and STANDING, this article will suggest alternative approaches to help with accurate diagnosis of patients with acute dizziness or vertigo.

Diversity of Participation in Clinical Trials and Influencing Factors: Findings from the Health Information National Trends Survey 2020.

BACKGROUND: Clinical trial diversity is critical to advance health and health equity. Research addressing the discrepancy between goals of achieving clinical trial diversity and realities of study enrollment remains underdeveloped. OBJECTIVE: This study aims to examine the association between race/ethnicity and clinical trial invitation, participation, knowledge, and sources of influence on clinical trial participation. DESIGN AND PARTICIPANTS: A cross-sectional, observational study using nationally representative data from 3689 US adults (≥ 18 years of age) who responded to the Health Information National Trends Survey fielded from February 24 to June 15, 2020. MAIN MEASURES: Primary outcomes included clinical trial invitation, participation, knowledge, and sources of influence on participation. The independent variable of interest is self-reported race/ethnicity. KEY RESULTS: Respondents identifying as non-Hispanic Black (relative to non-Hispanic White) had higher odds of being invited into a clinical trial (adjusted odds ratio: 2.0, 95% confidence interval (CI): 1.1, 3.7), but no differences in odds of participation were observed by race/ethnicity. Respondents from all races/ethnicities reported that personal healthcare providers were the most trusted source of clinical trial information. Hispanic (marginal effect (ME): - 0.09; 95% CI: - 0.16, - 0.03), non-Hispanic Black (ME: - 0.11; 95% CI: - 0.18, - 0.04), and non-Hispanic other (ME: - 0.11; 95% CI: - 0.19, - 0.02) respondents had lower odds than non-Hispanic White respondents of saying they would be influenced "a lot" by their doctor encouraging participation. Non-Hispanic Black respondents had significantly lower odds (relative to non-Hispanic White) of indicating family encouragement would influence their clinical trial participation decision "a lot" (ME: - 0.09; 95%: CI: - 0.14, - 0.03). CONCLUSION: While personal healthcare providers were trusted sources of information, racial/ethnic minority populations noted lower odds of clinical trial participation influence from providers and family. Thus, it is imperative for the healthcare, government, and industry organizations to build trust in medicine and science.

Disparities in awareness of the HPV vaccine and HPV-associated cancers among racial/ethnic minority populations: 2018 HINTS.

OBJECTIVES: Human papillomavirus (HPV) is a common virus that currently infects nearly 80 million people in the United States (U.S.) and can lead to cancer. HPV vaccination provides safe, effective, and lasting protection against HPV infections. Nevertheless, vaccination rates remain suboptimal. The purpose of this study was to examine the relationship between sociodemographic characteristics, HPV and HPV vaccine awareness, and knowledge of HPV-associated cancers among U.S. adults. DESIGN: Using responses from 3504 U.S. adults (aged 18 years and older) from the Health Information National Trends Survey 5 Cycle 2 (January-May 2018), we performed descriptive analysis to assess the level of awareness of HPV and HPV vaccines and knowledge of HPV-associated cancer. Multivariable regression analysis (including race, gender, age, level of education, marital status, number of children younger than 18) was conducted with weighted analysis. RESULTS: About 62% of respondents had heard of HPV and HPV vaccine. Asians had a lower level of awareness than non-Hispanic Whites of HPV (36.4% vs. 66.1%) and HPV vaccine (48.7% vs. 67.1%). Multivariable analysis showed that race/ethnicity was associated with outcomes, with Asians being less likely to have heard about HPV (aOR = 0.17, 95% CI: 0.07-0.38) and non-Hispanic Blacks (aOR = 0.57, 95% CI: 0.35-0.91) and Hispanics (aOR = 0.54, 95% CI: 0.36-0.80) being less likely to have heard of the HPV vaccine than non-Hispanic Whites. In addition, gender, age, marital status, and education were associated with awareness of HPV and the HPV vaccine; in particular, individuals who were female, younger (18-45), married, and more highly educated were more likely to have heard of HPV and HPV vaccine. CONCLUSION: Results highlight disparities in HPV and HPV vaccine awareness among racial/ethnic minority populations. Future interventions and legislation should target racial/ethnic minority populations to foster improvements in HPV vaccine uptake and reduce disparities in HPV-associated cancers.

A new portable Fresnel magnifying loupe for nystagmus observation: a clinical education and clinical practice setting study.

BACKGROUND: Dizziness is a common complaint of patients treated by primary care physicians. It is predominantly caused by peripheral vestibular disorders; however, central nervous system disorders should be excluded. Examination of the eye movements and nystagmus can help differentiate the disorders of the central nervous system from the peripheral vestibular disorders; however, it is often not performed appropriately. In medical education practice, nystagmus observation may facilitate an understanding of vestibular function and nystagmus characteristics. Thus, we proposed a medical education practice to master nystagmus observation using a recently developed portable Fresnel magnifying loupe that could be shielded by one eye. METHODS: Thirty-three students from the Department of Physical Therapy and the Department of Speech, Language, and Hearing Therapy of the Mejiro University participated in this study. Postrotatory nystagmus was measured and compared using the new loupe and control methods, namely the naked eye and Frenzel goggles; we rated the ease of visibility using a five-point scale. RESULTS: The number of detected cases of nystagmus was significantly higher with the new loupe than with the naked eye (p = 0.001). In addition, there were no significant differences in the nystagmus counts between the observations using the new loupe and Frenzel goggles (p = 0.087). No significant difference was observed in the visibility of eye movements between the loupe and naked eye (p = 1.00). The Frenzel goggles provided better visibility compared to that by the loupe (p = 0.034); however, none of the participants reported poor visibility using any of these methods. CONCLUSIONS: Our newly developed Fresnel loupe allows for the observation of nystagmus counts a level of reduction in fixation suppression similar to that of Frenzel goggles in an educational practice setting. Furthermore, it enables the detection of significantly more nystagmus counts compared to that by the naked eye. It offers several advantages over Frenzel goggles, including its lightweight, thin, durable, and portable design. Additionally, the loupe does not rely on a power source and can be used under normal room lighting conditions. TRIAL REGISTRATION: This study was approved by the Medical Research Ethics Committee of Mejiro University (approval number: 21medicine-021).

Mairá-Potato (Casimirella sp.): Botanical, Food, Pharmacological, and Phytochemical Aspects.

Millions of people in the world live in food insecurity, so identifying a tuber with characteristics capable of meeting the demand for food and also identifying active compounds that can be used to minimize harm to human health is of great value. The aim was to carry out a review based on systematic review tools and the main objective was to seek information on botanical, food, pharmacological, and phytochemical aspects of Casimirella sp. and propose possible applications. This review showed papers that addressed botanical, food, pharmacological, and phytochemical aspects of the Mairá-potato and presented suggestions for using this tuber allied to the information described in the works found in the Google Academic, Scielo, Science Direct, Scopus, PubMed, and Web of Science databases. This review synthesized knowledge about the Mairá-potato that can contribute to the direction of further research on the suggested technological applications, both on the use of this tuber as a polymeric material and its use as biomaterial, encapsulation, bioactive use, and 3D printing, because this work collected information about this non-conventional food plant (PANC) that shows great potential for use in various areas of study.

A prospective study on the application of HINTS in distinguishing the localization of acute vestibular syndrome.

BACKGROUND: Acute vestibular syndrome (AVS) is a common clinical syndrome in neurology clinics and emergency department. Canonical standard for AVS diagnosis requires the presence of persistent vertigo for more than 24 h. HINTS (head impulse-nystagmus-test of skew) is an emerging scheme in the diagnosis of AVS. In this prospective study, we evaluated the specificity and sensitivity of HINTS in distinguishing between central and peripheral AVS. METHODS: A cohort of 239 cases with complete clinical record was recruited in the study. All patients completed emergency brain CT examination to exclude hemorrhagic stroke. HINTS examination was conducted to distinguish between central AVS and peripheral AVS, and all patients completed head MRI, BAEP and vestibular function examinations within one week. Patients diagnosed as central AVS were subject to angiography (CTA/MRA/DSA), and patients with peripheral AVS were considered for a 3-month follow-up to correct the initial diagnosis. RESULTS: Patients with central AVS were associated with an elder age, higher incidences of hypertension, atrial fibrillation, family history of stroke and previous history of stroke. Posterior circulation cerebral infarction, vestibular migraine and cerebellitis were the dominant diseases associated with central AVS. The sensitivities of HIT, GE, and TS in the diagnosis of central AVS were 73.5%, 61.2%, and 26.5%, and the specificities were 97.9%, 92.6%, and 93.2% respectively. CONCLUSIONS: The sensitivity of HINTS for central AVS diagnosis is 89.8% and the specificity is 84.2%. HINTS is an easy-to-operate, low-cost, high-sensitivity and specific examination technique, which is practical in neurology outpatient clinics and emergency departments.

Perception of worry of harm from air pollution: results from the Health Information National Trends Survey (HINTS).

BACKGROUND: Air pollution exposure has been associated with a multitude of diseases and poses a significant concern to public health. For targeted environmental risk communication and interventions to be effective, it is important to correctly identify characteristics associated with worry of harm from air pollution. METHODS: Using responses from 3,630 participants of the Health Information National Trends Survey 4 Cycle 2, we assessed worry of harm from exposure to indoor (IAP) and outdoor (OAP) air pollution separately. Multinomial logistic regression models were used to calculate odds ratios and 95% confidence intervals. RESULTS: Hispanics were more likely to worry about harm from IAP and OAP compared to non-Hispanic whites. Participants who lived in metropolitan counties were more likely to worry about harm from IAP and OAP compared to those who lived in rural counties. Finally, those who believed their chance of getting cancer was high were more likely to worry about harm from IAP and OAP compared to those who thought their likelihood of getting cancer was low. CONCLUSIONS: Worry of harm from IAP and OAP varied across sociodemographic and cancer-related characteristics. Public health professionals should consider these characteristics when developing targeted environmental risk communication and interventions.

Prevalence, Factors, and Association of Electronic Communication Use With Patient-Perceived Quality of Care From the 2019 Health Information National Trends Survey 5-Cycle 3: Exploratory Study.

BACKGROUND: Electronic communication (e-communication), referring to communication through electronic platforms such as the web, patient portal, or mobile phone, has become increasingly important, as it extends traditional in-person communication with fewer limitations of timing and locations. However, little is known about the current status of patients' use of e-communication with clinicians and whether the use is related to the better patient-perceived quality of care at the population level. OBJECTIVE: The aim of this study was to explore the prevalence of and the factors associated with e-communication use and the association of e-communication use with patient-perceived quality of care by using the nationally representative sample of the 2019 Health Information National Trends Survey 5 (HINTS 5)-Cycle 3. METHODS: Data from 5438 adult responders (mean age 49.04 years, range 18-98 years) were included in this analysis. Multiple logistic and linear regressions were conducted to explore responders' personal characteristics related to their use of e-communication with clinicians in the past 12 months and how their use was related to perceived quality of care. Descriptive analyses for e-communication use according to age groups were also performed. All analyses considered the complex survey design using the jackknife replication method. RESULTS: The overall prevalence of e-communication use was 60.3%, with a significantly lower prevalence in older adults (16.6%) than that in <45-year-old adults (41%) and 45-65-year-old adults (42.4%). All percentages are weighted; therefore, absolute values are not shown. American adults who used e-communication were more likely to be high school graduates (odds ratio [OR] 1.95, 95% CI 1.14-3.34; P=.02), some college degree holders (OR 3.34, 95% CI 1.84-6.05; P<.001), and college graduates or more (OR 4.89, 95% CI 2.67-8.95; P<.001). Further, people who were females (OR 1.47, 95% CI 1.18-1.82; P=.001), with a household income ≥US $50,000 (OR 1.63, 95% CI 1.23-2.16; P=.001), with more comorbidities (OR 1.22, 95% CI 1.07-1.40; P=.004), or having a regular health care provider (OR 2.62, 95% CI 1.98-3.47; P<.001), were more likely to use e-communication. In contrast, those who resided in rural areas (OR 0.61, 95% CI 0.43-0.88; P=.009) were less likely to use e-communication. After controlling for the sociodemographics, the number of comorbidities, and relationship factors (ie, having a regular provider and trusting a doctor), e-communication use was found to be significantly associated with better perceived quality of care (ß=.12, 95% CI 0.02-0.22; P=.02). CONCLUSIONS: This study confirmed the positive association between e-communication use and patient-perceived quality of care and suggested that policy-level attention should be raised to engage the socially disadvantaged (ie, those with lower levels of education and income, without a regular health care provider, and living in rural areas) to maximize e-communication use and to support better patient-perceived quality of care among American adults.

Is there an association between a history of military service and cancer diagnosis? Results from a US national-level study of self-reported outcomes.

PURPOSE: To examine cancer prevalence in men with and without military service history, using national-level self-reported outcomes. METHODS: A cross-sectional survey-based US study, including men aged 18 and above from the Health Information National Trends Survey database between 2011 and 2014. The primary endpoint was self-reported cancer prevalence. Multivariable logistic regression analyses assessed the association of various covariates with the prevalence of cancer. RESULTS: A total of 4,527 men were analyzed, with 1,352 (29.9%) reporting a history of military service. Compared to men with no military service history, men with a military service history were older (median of 65 [IQR 56, 74] vs. 53 [IQR 41, 62] years, p < 0.0001), more commonly Caucasian (71.4% vs. 61.4%, p < 0.0001), born in the US (95.6% vs. 79.5%, p < 0.0001), attained higher education level and annual household income (p < 0.0001), and consisted of more smokers(58.3% vs. 44.5%, p < 0.0001). The age-adjusted comparison demonstrated a higher cancer prevalence in men with military service history (20.5% vs. 7.6%, p < 0.0001). Specifically, genitourinary, dermatological, gastrointestinal, and hematological cancers were generally more prevalent. Adjusting for all available confounders, multivariable models showed that military service history was associated with 1.56 (95% CI 1.20-2.03), and 1.57 (95% CI 1.07-2.31) increased odds of having any cancer, and specifically genitourinary cancer, respectively. CONCLUSIONS: Further research is needed to ascertain whether the association between military service and increased cancer diagnosis results from better screening programs or increased exposure to risk factors during military service.

Usability of the head impulse test in routine clinical practice in the emergency department to differentiate vestibular neuritis from stroke.

BACKGROUND AND PURPOSE: The bedside head impulse test (bHIT) is used to differentiate vestibular neuritis (VN) from posterior circulation stroke (PCS) in patients presenting with acute vestibular syndrome (AVS). If assessed by neuro-otological experts, diagnostic accuracy is high. We report on its diagnostic accuracy when applied by nonexperts during routine clinical practice in the emergency department (ED), its impact on patient management, and the potential diagnostic yield of the video-oculography-supported head impulse test (vHIT). METHODS: Medical chart review of 38 AVS patients presenting to our university medical center's ED, assessed by neurology residents. We collected bHIT results (abnormal/peripheral or normal/central) and whether patients were admitted to the stroke unit or general neurological ward. Final diagnosis (VN, n = 24; PCS, n = 14) was determined by clinical course, magnetic resonance imaging, and vHIT. RESULTS: The bHIT's accuracy was only 58%. Its sensitivity for VN was high (88%), but due to many false-abnormal bHITs in PCS (36%), the specificity was low (64%). The vHIT yielded excellent specificity (100%) and moderate sensitivity (67%). The decision on the patient's further care was almost arbitrary and independent from the bHIT: 58% of VN and 57% of PCS patients were admitted to the stroke unit. CONCLUSIONS: The bHIT, applied by nonexperts during routine practice in the ED, has low accuracy, is too often mistaken as abnormal/peripheral, and is not consistently used for patients' in-hospital triage. As false-abnormal bHITs can lead to misdiagnosis/mistreatment of stroke patients, we recommend that bHIT applied by nonexperts should be reassessed by a neuro-otological expert or preferably quantitative vHIT in the ED.

Bruns' nystagmus revisited: A sign of stroke in patients with the acute vestibular syndrome.

OBJECTIVE: Gaze-evoked nystagmus (GEN) is a central sign in patients with the acute vestibular syndrome (AVS); however, discriminating between a pathological and a physiologic GEN is a challenge. Here we evaluate GEN in patients with AVS. METHODS: In this prospective cross-sectional study, we used video-oculography (VOG) to compare GEN in the light (target at 15° eccentric) in 64 healthy subjects with 47 patients seen in the emergency department (ED) who had AVS; 35 with vestibular neuritis and 12 with stroke. All patients with an initial non-diagnostic MRI received a confirmatory, delayed MRI as a reference standard in detecting stroke. RESULTS: Healthy subjects with GEN had a time constant of centripetal drift >18 s. VOG identified pathologic GEN (time constant ≤ 18 s) in 33% of patients with vestibular strokes, specificity was 100%, accuracy was 83%. Results were equivalent to examination by a clinical expert. As expected, since all patients with GEN had a SN in straight-ahead position, they showed the pattern of a Bruns' nystagmus. CONCLUSIONS: One third of patients with AVS due to central vestibular strokes had a spontaneous SN in straight-ahead gaze and a pathological GEN, producing the pattern of a Bruns' nystagmus with a shift of the null position. The localization of the side of the lesion based on the null was not consistent, presumably because the circuits underlying gaze-holding are widespread in the brainstem and cerebellum. Nevertheless, automated quantification of GEN with VOG was specific, and accurately identified patients in the ED with AVS due to strokes.

Factors Affecting the Extent of Patients' Electronic Medical Record Use: An Empirical Study Focusing on System and Patient Characteristics.

BACKGROUND: Patients' access to and use of electronic medical records (EMRs) places greater information in their hands, which helps them better comanage their health, leading to better clinical outcomes. Despite numerous benefits that promote health and well-being, patients' acceptance and use of EMRs remains low. We study the impact of predictors that affect the use of EMR by patients to understand better the underlying causal factors for the lower use of EMR. OBJECTIVE: This study aims to examine the critical system (eg, performance expectancy and effort expectancy) and patient characteristics (eg, health condition, issue involvement, preventive health behaviors, and caregiving status) that influence the extent of patients' EMR use. METHODS: We used secondary data collected by Health Information National Trends Survey 5 cycle 3 and performed survey data analysis using structural equation modeling technique to test our hypotheses. Structural equation modeling is a technique commonly used to measure and analyze the relationships of observed and latent variables. We also addressed common method bias to understand if there was any systematic effect on the observed correlation between the measures for the predictor and predicted variables. RESULTS: The statistically significant drivers of the extent of EMR use were performance expectancy (ß=.253; P<.001), perceived behavior control (ß=.236; P<.001), health knowledge (ß=-.071; P=.007), caregiving status (ß=.059; P=.013), issue involvement (ß=.356; P<.001), chronic conditions (ß=.071; P=.016), and preventive health behavior (ß=.076; P=.005). The model accounted for 32.9% of the variance in the extent of EMR use. CONCLUSIONS: The study found that health characteristics, such as chronic conditions and patient disposition (eg, preventive health behavior and issue involvement), directly affect the extent of EMR use. The study also revealed that issue involvement mediates the impact of preventive health behaviors and the presence of chronic conditions on the extent of patients' EMR use.

Perceived Needs Versus Predisposing/Enabling Characteristics in Relation to Internet Cancer Information Seeking Among the US and Chinese Public: Comparative Survey Research.

BACKGROUND: Since the rise of the internet, online health information seeking has become a worldwide phenomenon. However, health and health communication are inherently culture bound. A data-driven cross-country comparison enables us to better understand how cultural factors moderate the association between individual-level determinants and online health information seeking. OBJECTIVE: The objective of the study was to examine similarities and differences in determinants of internet cancer information seeking between the US and Chinese general public (excluding cancer patients and survivors) under the framework of a behavioral model of health services use. METHODS: This study used Health Information National Trends Survey (HINTS) 2017 (US data) and HINTS-China 2017 data to answer the research question. It focused on people with no cancer history and with internet access. For the HINTS 2017, the sample size was 2153; for the HINTS-China 2017, the sample size was 2358. To compare China and the United States, the researchers selected the same set of study variables for each dataset. Under the framework of the behavioral model of health services use, these predictors were predisposing factors, enabling factors, and need factors. RESULTS: In terms of the predisposing factors, a higher age, college degree or above, being currently unemployed, and having a family history of cancer were associated with internet cancer information seeking for the Chinese respondents; none of these factors were related to information seeking for the US respondents, although a lower age was associated with information seeking. Regarding the enabling conditions, lower trust in family members and friends as reliable information sources was the only factor associated with information seeking for the Chinese respondents, while no enabling factor was related to information seeking for the US respondents. Regarding the need factors, perceived health status was not related to information seeking for the Chinese respondents, while perception of poorer health condition was related to information seeking for the US respondents. Higher cancer fear was related to information seeking for both groups, but the magnitude of association was smaller for the Chinese respondents than for the US respondents. CONCLUSIONS: Overall, under the framework of the behavioral model of health services use, the results based on multivariate logistic regression reveal clear patterns of cross-country/cultural differences in the factors associated with internet cancer information seeking behaviors: predisposing characteristics and enabling conditions are more important in China, while perceived needs are more significant in the US. Such differences might reflect possible US-China differences in job environment (eg, job pressure) and culture (individualism vs collectivism and family structure).

The Bucket Test Improves Detection of Stroke in Patients With Acute Dizziness.

BACKGROUND: It is challenging to detect posterior circulation strokes in patients presenting to the emergency department (ED) with acute dizziness. The current approach uses a combinatorial head-impulse, nystagmus, and test-of-skew method and is sensitive enough to differentiate central causes from peripheral ones. However, it is difficult to perform and underused. Further, magnetic resonance imaging (MRI) of the brain is not always available and can have low sensitivity for detecting posterior circulation strokes. OBJECTIVES: We evaluated the feasibility and utility of the bucket test (BT), which measures the difference between patient's subjective perception of the visual vertical and the true vertical, as a screening tool for stroke in patients presenting to the ED with acute dizziness. METHODS: In this work, we prospectively enrolled 81 patients that presented to our academic medical center ED with dizziness as their chief complaint. The BT was performed 3 times for every patient. RESULTS: Seventy-one patients met the study criteria and were included in the analysis. Ten patients were excluded because of a history of drug-seeking behavior. There were no reported difficulties performing the BT. Six patients (8%) were diagnosed with ischemic stroke on MRI and 1 additional patient was diagnosed with transient ischemic attack and found to have a stroke on subsequent MRI. All 7 patients with dizziness attributed to cerebrovascular etiology had an abnormal BT, resulting in a sensitivity of 100% (95% confidence interval [CI] 59-100%). The specificity of the BT was 38% (95% CI 24-52%). The positive predictive value of the BT for detecting stroke was 18% (95% CI 15-21%). CONCLUSIONS: The BT is an easy, cheap, safe, and quick test that is feasible and sensitive to screen acutely dizzy patients for stroke in the ED.

Cancer/health communication and breast/cervical cancer screening among Asian Americans and five Asian ethnic groups.

Objectives: This paper is an examination of cancer/health communication factors (i.e. cancer/health information seeking, patient-provider communication (PPC), cancer screening information from providers) and screening for breast and cervical cancer among Asian Americans and five Asian ethnic groups (Chinese, Filipinos, Japanese, Koreans, Vietnamese) in comparison to Whites. Additionally, the relationship between cancer/health communication disparity and cancer screening gaps between Asian Americans and Whites was investigated. Design: Data comes from a nationally representative sample of 2011-2014 Health Information National Trends Surveys (HINTS). Results: Asian Americans and most Asian ethnic-groups reported significantly lower rates of cancer/health information seeking and lower evaluations for PPC as compared to Whites, though differences within Asian ethnic groups were observed (Koreans' greater cancer/health information seeking, Japanese' higher PPC evaluation). When the cancer/health communication factors were controlled, Asian Americans' odds of cancer screening were increased. Especially, Asian Americans' odds of adhering to the breast cancer screening guideline became nearly 1.4 times greater than Whites. Conclusion: This research demonstrates that health organizations, providers, and Asian American patients' collaborative efforts to increase the access to quality cancer information, to make culturally competent but straightforward screening recommendations, and to practice effective communication in medical encounters will contribute to diminishing cancer disparities among Asian Americans.
