Importance: The HEALing Communities Study (HCS) evaluated the effectiveness of the Communities That HEAL (CTH) intervention in preventing fatal overdoses amidst the US opioid epidemic.

Objective: To evaluate the impact of the CTH intervention on total drug overdose deaths and overdose deaths involving combinations of opioids with psychostimulants or benzodiazepines.

Design, Setting, And Participants: This randomized clinical trial was a parallel-arm, multisite, community-randomized, open, and waitlisted controlled comparison trial of communities in 4 US states between 2020 and 2023.

Article Synopsis
  • Ansa cervicalis stimulation (ACS) is being explored as a therapy for obstructive sleep apnea (OSA) by stabilizing the pharynx and addressing collapse of various flow-limiting structures in the airway.
  • A study involving 41 OSA participants measured the effects of ACS on airflow and identified the specific structures causing airflow limitations during sleep.
  • Results indicated that ACS significantly reduced the collapsibility of all tested airway structures, with the most marked effects observed on the palatal and oropharyngeal walls, while factors like lower apnea-hypopnea index were linked to greater improvements in airway pressure.

Article Synopsis
  • The study examines a community-based intervention aimed at reducing opioid-related overdose deaths by increasing the adoption of evidence-based practices including overdose education and naloxone distribution, medication treatment for opioid use disorder, and prescription safety.
  • In a cluster-randomized trial, 67 communities across Kentucky, Massachusetts, New York, and Ohio were assigned to either receive the intervention or serve as a control group during a period marked by the COVID-19 pandemic and an increase in fentanyl overdoses.
  • Results showed no significant difference in opioid-related overdose death rates between the intervention and control groups, with both averaging similar rates, indicating that the community-engaged strategies did not have a measurable impact during the study period.

Grafting connects root and shoot systems of distinct individuals, bringing microbial communities of different genotypes together in a single plant. How do root system and shoot system genotypes influence plant microbiota in grafted grapevines? To address this, we utilized clonal replicates of the grapevine 'Chambourcin', growing ungrafted and grafted to three different rootstocks in three irrigation treatments. Our objectives were to (1) characterize the microbiota (bacteria and fungi) of below-ground compartments (roots, adjacent soil) and above-ground compartments (leaves, berries), (2) determine how rootstock genotype, irrigation, and their interaction influences grapevine microbiota in different compartments, and (3) investigate abundance of microorganisms implicated in the late-season grapevine disease sour rot ( and ).

Rationale: Receiving a healthcare provider's recommendation is a well-documented predictor of human papillomavirus (HPV) vaccination, and yet recommendations remain understudied and undertheorized.

Objective: To qualitatively describe strategies providers use to motivate HPV vaccination.

Method: We surveyed a national sample of 771 U.

Isolating DNA from microbes on the surface of a grape berry is a challenge due to their adhesion to the thick berry skin and cuticle, making studies of the grape microbiome challenging. We developed a field-to-lab DNA extraction procedure that starts in the vineyard, disrupts the grape berry surface while en route to the lab through agitation, and efficiently extracts microbial DNA from the surface of the grape. It is cost effective and utilizes commonly available laboratory chemicals with low toxicity (Table 1).

Sour rot is a disease complex produced by an interaction between grape berries and various species of yeast and acetic acid bacteria in the presence of Drosophila fruit flies. While yeast and bacteria are consistently found on healthy grape berries worldwide, we explored whether the composition of these epiphytic communities differed depending on the presence or absence of sour rot symptoms. Using high-throughput sequencing, we characterized the microbiome of sour rot-affected grapes from two geographical areas across two years.

Sour rot, a disease affecting berries of cultivated Vitis spp. worldwide, has not been clearly defined. Reported symptoms of the disease include browning of the berry skin, oozing of disintegrated berry pulp, and the smell of acetic acid, all in the presence of fruit flies (Drosophila spp.

Background: Improving healthcare providers' communication about HPV vaccination is critical to increasing uptake. We previously demonstrated that training providers to use presumptive announcements to introduce HPV vaccination improved uptake, whereas training them to use participatory conversations had no effect. To understand how communication training changed provider perceptions and communication practices, we evaluated intermediate outcomes and process measures from our randomized clinical trial, with a particular focus on identifying mechanisms that might explain the announcement training's impact.

Objective: Improving provider recommendations is critical to addressing low human papillomavirus (HPV) vaccination coverage. Thus, we sought to determine the effectiveness of training providers to improve their recommendations using either presumptive "announcements" or participatory "conversations."

Methods: In 2015, we conducted a parallel-group randomized clinical trial with 30 pediatric and family medicine clinics in central North Carolina.

Background: Physician communication about human papillomavirus (HPV) vaccine is a key determinant of uptake. To support physician communication, we sought to identify messages that would motivate HPV vaccination.

Methods: From 2014 to 2015, we surveyed national samples of parents of adolescents ages 11 to 17 (n = 1,504) and primary care physicians (n = 776).

Background: Improving the quality of physicians' recommendations for human papillomavirus (HPV) vaccination is critical to addressing low coverage. Thus, we sought to describe HPV vaccine communication practices among primary care physicians.

Methods: Pediatricians and family physicians (n = 776) completed our national online survey in 2014.

Background: Low human papillomavirus (HPV) vaccination coverage stands in stark contrast to our success in delivering other adolescent vaccines. To identify opportunities for improving physicians' recommendations for HPV vaccination, we sought to understand how the communication context surrounding adolescent vaccination varies by vaccine type.

Methods: A national sample of 776 U.
