RESUMEN
OBJECTIVE: To assess physician-patient communication and identify the frequency of use of specific communication techniques by analyzing recordings of routinely scheduled medical encounters for patients with clinician-identified chronic migraine. BACKGROUND: Chronic migraine is an under-diagnosed, under-treated, and highly burdensome disease. Effective medical communication is integral to optimal medical care, including providing accurate diagnoses, creating effective treatment plans, and enhancing patient adherence. Communication patterns during office visits may be a target for intervention to improve outcomes for people with chronic migraine. DESIGN: This was a prospective, observational study based on analysis of audio recordings collected during neurologist-patient chronic migraine dialogues. METHODS: Twenty neurologists from a US neurology panel maintained by Verilogue, Inc., a research organization specializing in healthcare dialogues, were invited to identify patients with chronic migraine and record clinical encounters with their patients. Both new patient visits and follow-up visits were included in this analysis. Neurologist-patient dialogues were audio-recorded, anonymized, transcribed, and analyzed by a sociolinguist for the presence of prespecified communication parameters, strategies, and specific language indicative of optimal migraine-related medical care. RESULTS: Fourteen out of the 20 invited neurologists (70.0%) accepted the study invitation and recorded 35 encounters with patients eligible for the study. The patient sample was 91.4% female (n = 32/35), with a mean age of 46 years. On average, there were 17 headache-related questions per visit; 82.0% of questions were closed-ended (n = 369/450). Headache/migraine frequency was elicited in 77.1% of the dialogues (n = 27/35), but headache days per month was assessed in only a single dialogue. Only one neurologist utilized the ask-tell-ask technique. Headache-related disability was discussed in 22.9%of the dialogues (n = 8/35), with only one using open-ended questions. None of the dialogues discussed ictal vs interictal headache-related disability. Chronic migraine was mentioned in 8.6% of dialogues (n = 3/35) and treatment plans were discussed in 37.1% of the dialogues (n = 13/35). CONCLUSIONS: Results from this preliminary study showed that the majority of the neurologist-chronic migraine patient dialogues did not assess elements crucial for diagnosis and treatment (eg, headache days per month and headache related disability) or use standard communication techniques (eg, open-ended questions, ask-tell-ask). We recommend intervention studies designed to assess the benefits of improved communication on diagnostic accuracy, treatment decisions, and patient reported outcomes.

BACKGROUND: Oxymetazoline cream 1.0% is FDA-approved for the topical treatment of persistent facial erythema associated with rosacea in adults. This phase 2, multicenter, randomized, double-blind, parallel-group study assessed the pharmacokinetics, safety, and tolerability of oxymetazoline in patients with moderate to severe erythema associated with rosacea. METHODS: Eligible patients were randomized to 1 of 8 treatment groups (oxymetazoline cream 0.5%, 1.0%, or 1.5% or vehicle applied topically either once or twice daily for 28 days). Pharmacokinetic analyses were conducted in patients receiving oxymetazoline. Plasma samples for pharmacokinetic assessments were collected prior to dosing and 6 times postdose on days 1 and 28. RESULTS: A total of 356 patients were included in the safety population (oxymetazoline, n=268; vehicle, n=88). Thirty patients (11.2%) in the oxymetazoline group reported treatment-related treatment-emergent adverse events, most of which were mild to moderate application-site reactions. Oxymetazoline, at all concentrations, was generally safe and well tolerated. Mean maximum observed plasma concentrations were ≤115 pg/mL across all groups; the highest mean values for area under the plasma concentration-time curve from time 0 to 24 hours following once- and twice-daily administration of oxymetazoline 1.5% were 1680 pgâ¢h/mL and 2660 pgâ¢h/mL, respectively. Systemic exposure to oxymetazoline increased dose proportionally with once- and twice-daily administration. CONCLUSION: These findings support the use of oxymetazoline for the treatment of persistent facial erythema associated with rosacea. J Drugs Dermatol. 2018;17(2):213-220.

OBJECTIVE: Effective health communication is critical for understanding and acting on health information. This cross-sectional study explored participants' understanding of their health condition, their preferences for receiving health communications, and their interest in receiving clinical trial results across several therapeutic areas. METHODS: The study recruited participants via social media, email newsletters, and advocacy organizations. An online screener captured demographic information (health conditions, age, race/ethnicity, gender, and education). Eligible participants were emailed an online survey assessing preferred sources and formats for receiving health information, interest in learning about topics related to the results of clinical trials, and health literacy levels. RESULTS: In total, 449 participants (median age, 35 years [range, 18-76]; White, 53%; higher education, 65%; mean (range) health literacy score, 1.9 [0.4-3.0]) from 45 US states completed the survey representing 12 disease indications (bipolar, blood and solid tumor cancers, irritable bowel syndrome, inflammatory bowel disease, major depressive disorder, migraine, Parkinson's, psoriasis/atopic dermatitis, retinal vein occlusion/macular degeneration, rheumatoid arthritis, and spasticity). Healthcare providers were the preferred source of health information (59%), followed by Internet searches (11%). Least preferred sources were social media (5%), friends/family (3%), and email newsletters (2%). Participants preferred multiple formats and ranked reading materials online as most preferred (33%), along with videos (28%) and infographics (27%). Printed materials (14%) and audio podcasts (9%) were the least preferred formats. A majority of the participants reported that the health information they found was hard to understand (57%) and confusing (62%). Most participants (85%) were somewhat/very interested in learning about clinical trial results, with the highest interest in short summaries of safety (78%) and efficacy (74%) results. CONCLUSION: Effective health communication may be achieved via multiple formats shared directly by healthcare providers.
Researchers wanted to learn how people preferred to receive health-related communications, including information about the results of clinical trials. They surveyed 449 people from 45 US states with 12 different health conditions. The survey questions asked people about their preferred sources and ways of getting health information. It also asked about their interest in learning about clinical trials related to their health condition. The results showed that most people preferred to get health information from their healthcare providers (59%). The Internet was the second most popular choice (11%) for getting health information. People did not like getting health information from social media, friends or family, or email newsletters as much. When it came to how health information was shared, people liked reading materials online (33%), watching videos (28%), and looking at infographics (27%). They did not like printed materials and audio podcasts as much. Most people (85%) were interested in learning about the results of clinical trials in short summaries. They wanted to know about the safety (78%) and how well the treatments worked (74%) in the short summaries. In conclusion, people liked getting health information from healthcare providers like doctors, nurses, and others in different formats. Sharing information in different formats through healthcare providers may improve communication for patients with different health conditions.
RESUMEN
Social behaviors are among the most important motivated behaviors. How dopamine (DA), a "reward" signal, releases during social behaviors has been a topic of interest for decades. Here, we use a genetically encoded DA sensor, GRABDA2m, to record DA activity in the nucleus accumbens (NAc) core during various social behaviors in male and female mice. We find that DA releases during approach, investigation and consummation phases of social behaviors signal animals' motivation, familiarity of the social target, and valence of the experience, respectively. Positive and negative social experiences evoke opposite DA patterns. Furthermore, DA releases during mating and fighting are sexually dimorphic with a higher level in males than in females. At the functional level, increasing DA in NAc enhances social interest toward a familiar conspecific and alleviates defeat-induced social avoidance. Altogether, our results reveal complex information encoded by NAc DA activity during social behaviors and their multistage functional roles.

BACKGROUND AND OBJECTIVES: To examine the efficacy of ubrogepant in the treatment of migraine with mild vs moderate or severe pain. METHODS: This was a phase 3, open-label, dose-blinded, 52-week extension trial. Adults with migraine were randomized 1:1:1 (usual care, ubrogepant 50 mg, or ubrogepant 100 mg). Participants treated up to 8 migraine attacks of any pain intensity every 4 weeks. Efficacy outcomes (only collected for ubrogepant) included 2-hour pain freedom (2hPF), freedom from associated symptoms, and from disability. A generalized linear mixed model with binomial distribution and logit link function was used to assess the influence of baseline pain intensity on treatment outcomes in this post hoc analysis. RESULTS: Data for 19,291 attacks from 808 participants were included. 2hPF rates were higher for attacks treated when pain was mild vs moderate or severe: ubrogepant 50 mg (47.1% vs 23.6%; odds ratio [95% CI] 2.89 [2.57-3.24]) and ubrogepant 100 mg (55.2% vs 26.1%; 3.50 [3.12-3.92]; p < 0.0001 both doses). Rates of freedom from photophobia, phonophobia, and nausea 2 hours after treatment were also significantly higher following the treatment of mild vs moderate or severe pain (p < 0.001 all symptoms, both doses). At 2 hours, the proportion of attacks with normal function was more than double for both doses of ubrogepant (p < 0.001). The most common adverse event was upper respiratory tract infection (â¼11% both doses). Serious adverse events were reported by 2% in ubrogepant 50 mg and 3% in ubrogepant 100 mg. DISCUSSION: Relative to treatment of attacks with moderate or severe pain, treatment with ubrogepant during mild pain resulted in significantly higher rates of freedom from pain, freedom from associated symptoms, and achieving normal function 2 hours after administration. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov, NCT02873221. CLASSIFICATION OF EVIDENCE: This trial provides Class III evidence that treatment of migraine with ubrogepant when pain is mild vs moderate or severe increases the likelihood of achieving pain freedom, absence of symptoms, and normal function within 2 hours postdose.

The lymphatic vasculature is critical for lung function, but defects in lymphatic function in the pathogenesis of lung disease is understudied. In mice, lymphatic dysfunction alone is sufficient to cause lung injury that resembles human emphysema. Whether lymphatic function is disrupted in cigarette smoke (CS)-induced emphysema is unknown. In this study, we investigated the effect of CS on lung lymphatic function. Analysis of human lung tissue revealed significant lung lymphatic thrombosis in patients with emphysema compared to control smokers that increased with disease severity. In a mouse model, CS exposure led to lung lymphatic thrombosis, decreased lymphatic drainage, and impaired leukocyte trafficking that all preceded the development of emphysema. Proteomic analysis demonstrated an increased abundance of coagulation factors in the lymph draining from the lungs of CS-exposed mice compared to control mice. In addition, in vitro assays demonstrated a direct effect of CS on lymphatic endothelial cell integrity. These data show that CS exposure results in lung lymphatic dysfunction and a shift in thoracic lymph towards a prothrombic state. Furthermore, our data suggest that lymphatic dysfunction is due to effects of CS on the lymphatic vasculature that precede emphysema. These studies demonstrate a novel component of CS-induced lung injury that occurs early in the pathogenesis of emphysema.

Active defense against a conspecific aggressor is essential for survival. Previous studies revealed strong c-Fos expression in the ventrolateral part of the ventromedial hypothalamus (VMHvl) in defeated animals. Here, we examined the functional relevance and in vivo responses of the VMHvl during conspecific defense. We found that VMHvl cells expressing estrogen receptor α (Esr1) are acutely excited during active conspecific defense. Optogenetic inhibition of the cells compromised an animal's ability to actively defend against an aggressor, whereas activating the cells elicited defense-like behaviors. Furthermore, the VMHvl is known for its role in aggression. In vivo recording and c-Fos mapping revealed differential organization of the defense and aggression-responsive cells in the VMHvl. Specifically, defense-activated cells are concentrated in the anterior part of the VMHvl, which preferentially targets the periaqueductal gray (PAG). Thus, our study identified an essential neural substrate for active conspecific defense and expanded the function of the VMHvl.
