Patterns of E-Cigarette Use Among Primary Care Patients at an Urban Community Center

Tobacco use remains the leading cause of preventable disease and death in the US. The number of tobacco products has grown over the past decade. E-cigarette use has increased rapidly in recent years, but patterns and correlates of use have not been thoroughly assessed. We examined relationships among demographic factors, e-cigarette and conventional cigarette use in a large sample (N?=?12,409) of adult patients at a community health center in the Northeastern US. Overall, 13% (N?=?1675) of the sample reported ever using e-cigarettes. In logistic regression models, ever having used e-cigarettes was associated with younger age (ages 18–25; OR?=?3.5, p?<?0.001). Being transgender (OR?=?1.8, p?<?0.001), bisexual (OR?=?1.5, p?<?0.001), un-partnered (OR?=?1.5, p?<?0.001), having a lower income (OR?=?1.6, p?<?0.001) or a high BMI (OR?=?1.4, p?=?0.009) were associated with increased odds of use, whereas being a woman (OR?=?0.7, p?<?0.001) or Black/African American (OR?=?0.7, p?=?0.007) were associated with lower odds of use. Of the participants who reported e-cigarette use, a majority also endorsed current or former use of conventional cigarettes. Individuals who formerly used conventional cigarettes were nearly three times more likely to report daily e-cigarette use than current users. Among primary care patients at a community health center, e-cigarette use was reported by a sizeable portion of the sample. Overall, odds of use were higher in certain patient populations, and individuals who formally used cigarettes were more likely to report e-cigarette use than individuals who currently smoke, suggesting that e-cigarettes may be functioning as a cessation aid or a strategy to reduce conventional cigarette use.

     

Creating patient-centered radiology reports to empower patients undergoing prostate magnetic resonance imaging

IntroductionAs we progress to an era when patient autonomy and shared decision-making are highly valued, there is a need to also have effective patient-centered communication tools. Radiology reports are designed for clinicians and can be very technical and difficult for patients to understand. It is important for patients to understand their magnetic resonance imaging (MRI) report in order to make an informed treatment decision with their physician. Therefore, we aimed to create a patient-centered prostate MRI report to give our patients a better understanding of their clinical condition.MethodsA prototype patient-centered radiology report (PACERR) was created by identifying items to include based on opinions sought from a group of patients undergoing prostate MRI and medical experts. Data was collected in semi-structured interviews using a salient belief question. A prototype PACERR was created in collaboration with human factors engineering and design, medical imaging, biomedical informatics, and cancer patient education groups.ResultsFifteen patients and eight experts from urology, radiation oncology, radiology, and nursing participated in this study. Patients were particularly interested to have a report with laymen terms, concise language, contextualization of values, definitions of medical terms, and next course of action. Everyone believed the report should include the risk of MRI findings actually being cancer in the subsequent biopsy.ConclusionsA prostate MRI PACERR has been developed to communicate the most important findings relevant to decision-making in prostate cancer using patient-oriented design principles. The ability of this tool to improve patient knowledge and communication will be explored.     

Understanding the messages and motivation of vaccine hesitant or refusing social media influencers

BackgroundWhile anti-vaccine messages on social media have been studied for content, reach, and effectiveness, less is known about those who create and promote the messages. Online influencers, or ‘everyday people who are influential within their online social networks’, are viewed as trusted voices who are often making similar life decisions as their followers. Therefore, their experiences with and perspectives on health issues can be persuasive.MethodsWe collaborated with a formal network of online influencers to interview, using a semi-structured interview guide, vaccine hesitant influencer mothers about their views on vaccination; their process for developing health-related social media content; their motivation to promote anti-vaccine messages; and their opinions on current vaccination messaging. Prescreening ensured a diverse sample by race/ethnicity, age, education, number of children, and geographic residence. Interviews occurred by telephone, were audio recorded, and transcribed. Themes were generated independently by two coders using a deductive coding approach.ResultsWe interviewed 15 online influencer mothers from across the U.S. (average age 39 years old; all married; 13 Caucasian, 1 African American, 1 Hispanic). In some capacity, 5 of the 15 wrote about vaccination on their blog. Those who chose not to post anti-vaccine content did so for fear of alienating followers or having their platform be the site of combative discourse among readers. When researching their social media posts, the influencers did not trust mainstream sources of health information and relied on alternative sources and search engines.Implications: This exploratory study interviewed influential mothers who have the ability to spread anti-vaccine messages on social media. While most do not contribute to the anti-vaccine sentiment, understanding the motivation and practices of those that do assists the public health community in better understanding the online vaccination communication environment, leading to more effective messages to counterbalance anti-vaccine content on social media.     

Unhealthy eating behaviour in adolescents

In recent years, eating disorders (Anorexia and Bulimia Nervosa) have increased and are appearing at increasingly younger ages. They affect predominantly adolescent females 12 to 25 years of age. The objective of this study of adolescents is to detect and discuss unhealthy eating behaviour, defined by either of two factors: (1) following a slimming diet not advised or supervised by any person trained in health care; or (2) eating very large quantities at irregular times, not related to anxiety or stress. A transversal study has been undertaken of 630 school children of 14–18 years of age (average: 15.9 years) in Cádiz (Andalucia, Spain), using an anonymous self-reporting questionnaire to collect data on personal and educational situation, on eating habits, on nutritive intake and knowledge of nutrition, and on dieting and physical exercise. The study has considered averages, ratios, statistical significance (x ²) and, as a measure of risk, the Disequality Ratio of Prevalence (DRP). Anomalous eating behaviour was detected in 46.3% (292), with females predominant by a ratio of 2:1. Comparing groups with anomalous and with normal eating habits, significant differences were detected in respect of: perception of body image (p<0.001), frequency of weighing oneself (p<0.05), periods of abstinence from eating (DRP 1.66; 95% confidence interval (CI): 1.66–2.37), provocation of vomiting (DRP 2.02; 95% CI: 1.13–3.65), use of laxatives (DRP 4.25; 95% CI: 1.08–9.63), and the exclusion of certain meals and types of food, mainly bread and cereals, fats and sugars. Conclusions are drawn on the substantial scale of unhealthy eating behaviour among adolescents in Cadiz. More adequate education on personal health and related social issues should be provided.     

Injection of endothelin-1 into the raphe obscurus of rats induces depressor responses predominantly through endothelin ETA receptors

We used in vitro autoradiography to identify the endothelin-1 receptor subtype(s) in the nucleus raphe obscurus of rats. These studies showed dense binding of [¹²⁵I]PD151242 (for endothelin ET_A receptors), while tissues incubated with [¹²⁵I]BQ3020 (for endothelin ET_B receptors) had low binding. In addition, we examined the effects of the endothelin receptor antagonists FR 139317 (endothelin ET_A receptor-selective antagonist), SB 209670 (endothelin ET_A/ET_B receptor-non-selective antagonist) and BQ-788 (endothelin ET_B receptor-selective antagonist) on the blood pressure responses following administration of endothelin-1 into the nucleus raphe obscurus. The basal mean arterial blood pressure (MABP) of the rats was 110 ± 7 mmHg (n = 5). This was decreased in a dose-dependent manner by endothelin-1 (0.1, 1 and 10 pmol) microinjected into the nucleus raphe obscurus. This effect occurred within 1–6 s and recovered within 4 ± 1.2 min at a dose of 10 pmol. The doses of 0.1 pmol and 1 pmol ET-1 had responses which lasted 1 ± 0.4 min and 2 ± 0.2 min, respectively. Small decreases in heart rate accompanied the MAP responses to endothelin-1. For instance, the heart rate decreased by 16 ± 4 beats min^–1 after 10 pmol endothelin-1 (control, 366 ± 6 beats min^–1, n = 5). Decreases in blood pressure induced by endothelin-1 were greatly reduced by pre-administration to the nucleus raphe obscurus of FR139317 (5 nmol/rat) or SB209670 (3 nmol/rat; 97 ± 7% and 95 ± 6%, P < 0.01, n = 5, respectively), but were not affected by BQ-788 (50 nmol/rat; 8 ± 3%, P > 0.05, n = 5). The antagonists did not influence heart rate when injected to the nucleus raphe obscurus prior to endothelin-1. FR139317 (0.5 nmol) and SB209670 (0.3 nmol) had no effects on endothelin-induced changes in arterial blood pressure. Therefore, the autoradiographic study showed that there are binding sites for ET-1 within the nucleus raphe obscurus of rats, which are predominantly of ET_A type. The in vivo study showed that ET_A receptors are the predominant mediators of depressor responses induced by endothelin-1 injected into this nucleus.
