    Abstract Nucleoli are membrane-less structures located within the nucleus and are known to be involved in many cellular functions, including stress response and cell cycle regulation. Besides, many viruses can employ the nucleolus or nucleolar proteins to promote different steps of their life cycle such as replication, transcription and assembly. While adeno-associated virus type 2 (AAV2) capsids have previously been reported to enter the host cell nucleus and accumulate in the nucleolus, both the role of the nucleolus in AAV2 infection, and the viral uncoating mechanism remain elusive. In all prior studies on AAV uncoating, viral capsids and viral genomes were not directly correlated on the single cell level, at least not in absence of a helper virus. To elucidate the properties of the nucleolus during AAV2 infection and to assess viral uncoating on a single cell level, we combined immunofluorescence analysis for detection of intact AAV2 capsids and capsid proteins with fluorescence in situ hybridization for detection of AAV2 genomes. The results of our experiments provide evidence that uncoating of AAV2 particles occurs in a stepwise process that is completed in the nucleolus and supported by alteration of the nucleolar structure.

    Abstract Medulloblastoma is one of the most common malignant brain tumors of children, and 30% of medulloblastomas are driven by gain-of-function genetic lesions in the Sonic Hedgehog (SHH) signaling pathway. EYA1, a haloacid dehalogenase phosphatase and transcription factor, is critical for tumorigenesis and proliferation of SHH medulloblastoma (SHH-MB). Benzarone and benzbromarone have been identified as allosteric inhibitors of EYA proteins. Using benzarone as a point of departure, we developed a panel of 35 derivatives and tested them in SHH-MB. Among these compounds, DS-1-38 functioned as an EYA antagonist and opposed SHH signaling. DS-1-38 inhibited SHH-MB growth in vitro and in vivo, showed excellent brain penetrance, and increased the lifespan of genetically engineered mice predisposed to fatal SHH-MB. These data suggest that EYA inhibitors represent promising therapies for pediatric SHH-MB.
    Significance: Development of a benzarone derivative that inhibits EYA1 and impedes the growth of SHH medulloblastoma provides an avenue for improving treatment of this malignant pediatric brain cancer.

    Abstract Home-packed lunches have been found to be of lower nutritional quality than school-bought lunches, yet little is known about family-based factors associated with lunch packing. The current exploratory study examines parental and family predictors of fruits and vegetables packed in lunches, hypothesizing parents' nutrition knowledge and authoritative parenting as well as children's involvement in lunch decisions would relate to packing more fruits and vegetables, while financial difficulties would relate to packing fewer. Ninety parent-child dyads from 4th-6th grade participated for 5 consecutive school days. Lunch contents were recorded using a digital imaging procedure to capture the number of days a fruit or vegetable was packed, and servings of fruits and vegetables in lunches each day. Parents completed family and parenting questionnaires and daily reports of child involvement in lunch decisions. Count-based regression models and longitudinal analyses within a multilevel modeling framework were used to examine predictors of lunch contents. Higher nutrition knowledge was associated with packing more fruit across the week and more vegetables on Monday. Authoritative parenting was associated with packing fewer vegetables on Monday, but more servings across the week. Financial stress was related to higher rates of never packing vegetables and when vegetables were packed including fewer servings, while child involvement in lunch decisions was associated with packing more fruits across the week, packing vegetables on more days and more servings of vegetables on Monday. Findings suggest parental and family factors impact the foods in packed lunches, with implications for children's dietary intake at school. Outreach programs can help parents pack more fruits and vegetables by providing nutrition education and suggestions for affordable, healthy lunch options as well as encouraging child involvement in the lunch packing process.

    Abstract Purpose: Evidence supports treatment for opioid use disorder (OUD) with buprenorphine in primary care practices (PCPs). Barriers that slow implementation of this treatment include inadequately trained staff. This study aimed to increase the number of rural PCPs providing OUD treatment with buprenorphine. This evaluation describes the impact of a practice team training on the implementation and delivery of OUD treatment with buprenorphine in PCPs of rural Colorado.
    Methods: Implementing Technology and Medication Assisted Treatment Team Training in Rural Colorado (IT MATTTRs) was a multilevel implementation study that included a practice-focused intervention to improve awareness, adoption, and use of buprenorphine treatment for OUD. Participating PCP teams received the IT MATTTRs Practice Team Training and support. Practices' implementation of treatment components was assessed before and after training. Practice-reported and population-level data from the Prescription Drug Monitoring Program were obtained to describe changes in delivery of treatment after training.
    Results: Forty-two practices received team training. Practices reported an average of 4.7 treatment-related components in place at baseline compared with 13.0 at 12-month follow-up (F[2,56] = 31.17,
    Conclusions: The IT MATTTRs training for PCP teams in OUD treatment with buprenorphine addressed elements beyond clinician waiver training to make implementation feasible and effectively increased implementation and delivery of this treatment in rural Colorado.

    Abstract Objective: School-based interventions and policies encourage youths to include and consume fruits and vegetables at lunchtime via school lunches, but limited research has examined how these behaviours compare when youths have home-packed lunches. The objective of the present study was to compare fruit and vegetable contents and consumption among students having school or home-packed lunches over the school week.
    Design: Participants were observed over five consecutive days at school lunchtime. Trained analysts estimated students' lunchtime fruit and vegetable contents and consumption using digital imaging. Mixed models examined associations between fruit and vegetable dietary behaviours and lunch source (school v. home-packed), controlling for student gender, grade and school.
    Setting: Three elementary schools in northern California, USA.ParticipantsFourth-, fifth- and sixth-grade students (nchildren 315; nobservations 1421).
    Results: Students were significantly less likely to have and to consume fruits and vegetables (all P<0·05) when having home-packed lunches, compared with when having school lunches. Among those who did have or did consume these foods, having a home-packed lunch was associated with consuming significantly less fruit (P<0·05) but no differences for other dietary outcomes.
    Conclusions: The study adds to a growing body of literature indicating shortfalls in fruit and vegetable contents and consumption associated with having a home-packed lunch, relative to having a school lunch. Findings suggest that school-based interventions, particularly when targeting home-packed lunches, should focus on whether or not these foods are included and consumed, with less emphasis on quantities.

    Abstract Although increasing attention is placed on the quality of foods in children's packed lunches, few studies have examined the capacity of observational methods to reliably determine both what is selected and consumed from these lunches. The objective of this project was to assess the feasibility and inter-rater reliability of digital imaging for determining selection and consumption from students' packed lunches, by adapting approaches previously applied to school lunches. Study 1 assessed feasibility and reliability of data collection among a sample of packed lunches (n = 155), while Study 2 further examined reliability in a larger sample of packed (n = 386) as well as school (n = 583) lunches. Based on the results from Study 1, it was feasible to collect and code most items in packed lunch images; missing data were most commonly attributed to packaging that limited visibility of contents. Across both studies, there was satisfactory reliability for determining food types selected, quantities selected, and quantities consumed in the eight food categories examined (weighted kappa coefficients 0.68-0.97 for packed lunches, 0.74-0.97 for school lunches), with lowest reliability for estimating condiments and meats/meat alternatives in packed lunches. In extending methods predominately applied to school lunches, these findings demonstrate the capacity of digital imaging for the objective estimation of selection and consumption from both school and packed lunches.

    Abstract Symptoms in the urogenital organs are common in multiple system atrophy (MSA), also in the years preceding the MSA diagnosis. It is unknown how MSA is triggered and these observations in prodromal MSA led us to hypothesize that synucleinopathy could be triggered by infection of the genitourinary tract causing ɑ-synuclein (ɑSyn) to aggregate in peripheral nerves innervating these organs. As a first proof that peripheral infections could act as a trigger in MSA, this study focused on lower urinary tract infections (UTIs), given the relevance and high frequency of UTIs in prodromal MSA, although other types of infection might also be important triggers of MSA. We performed an epidemiological nested-case control study in the Danish population showing that UTIs are associated with future diagnosis of MSA several years after infection and that it impacts risk in both men and women. Bacterial infection of the urinary bladder triggers synucleinopathy in mice and we propose a novel role of ɑSyn in the innate immune system response to bacteria. Urinary tract infection with uropathogenic E. coli results in the de novo aggregation of ɑSyn during neutrophil infiltration. During the infection, ɑSyn is released extracellularly from neutrophils as part of their extracellular traps. Injection of MSA aggregates into the urinary bladder leads to motor deficits and propagation of ɑSyn pathology to the central nervous system in mice overexpressing oligodendroglial ɑSyn. Repeated UTIs lead to progressive development of synucleinopathy with oligodendroglial involvement in vivo. Our results link bacterial infections with synucleinopathy and show that a host response to environmental triggers can result in ɑSyn pathology that bears semblance to MSA.
