Researchers, healthcare professionals, educators and policymakers have important responsibilities to improve the mental health of working adolescents.Purpose Understanding variability sources in early language interaction is critical to identifying children whose development is at risk and designing interventions. Variability across socioeconomic status (SES) groups has been extensively explored. However, SES is a limited individual clinical indicator. For example, it is not generally directly modifiable. The purpose of this study was to examine if child language ability, input quantity and quality, and dyadic interaction were associated with modifiable caregiver characteristics-self-efficacy and developmental knowledge. Method We conducted secondary analyses using the baseline data (n = 41 dyads enrolled, n = 30 analyzed) from a longitudinal study. Mothers and children (1;0-2;3 [years;months]) in low-income households completed demographic questionnaires, self-efficacy and developmental knowledge measures, child language assessments, and interaction samples. We used linear regression models to examine the relationship between self-efficacy, developmental knowledge, and outcomes. Results Child receptive and expressive language scores were significantly associated with mothers’ self-efficacy, knowledge, and Efficacy × Knowledge interaction. Specifically, maternal self-efficacy was positively associated with child language only in the context of high developmental knowledge. Neither self-efficacy nor developmental knowledge was significantly associated with the number of total or different words mothers produced. However, self-efficacy was significantly and positively associated with the rate of child-initiated conversational turns per minute, controlling for the number of child utterances. Mothers with higher self-efficacy responded more readily to their children than those with lower self-efficacy. Conclusions Child language ability and interaction quality vary based on modifiable parent characteristics. Modifiable individual characteristics should be considered in early language interaction within and across SES groups.

This study aimed to assess the prevalence of drinking and driving on roadways in urban areas and highways in Cameroon, and to determine the associations between drinking and driving and socio-demographic factors.

A cross-sectional study of motor vehicle drivers was performed on Fridays, Saturdays, and Sundays between May and September 2020 with three driver groups (1) random motor vehicle drivers (including riders) on major highways, (2) drivers recruited at car stations in Yaoundé, and (3) at fuel stations in Douala. JPH203 mouse Alcohol was measured using breathalyzers, and a questionnaire collected socio-demographic data.

In total, 2402 motor vehicle drivers were asked to participate in the study and 1701 (70.8%) gave informed consent. The vast majority (98.6%) were men. Drivers aged 30-39 years constituted the largest age group on highways and in Yaoundé, whereas 18-29 years was the largest age group in Douala. The highest prevalence of alcohol was observed among drivers in Yaoundé, which included mainly clandese better developed and enforced in order to reduce the number road traffic crashes.Introduction [227Th]Th-3,2-HOPO-MSLN-mAb, a mesothelin (MSLN)-targeted thorium-227 therapeutic conjugate, is currently in phase I clinical trial; however, direct PET imaging using this conjugate is technically challenging. Thus, using the same MSLN antibody, we synthesized 3,2-HOPO and deferoxamine (DFO)-based zirconium-89 antibody conjugates, [89Zr]Zr-3,2-HOPO-MSLN-mAb and [89Zr]Zr-DFO-MSLN-mAb, respectively, and compared them in vitro and in vivo. Methods [89Zr]Zr-3,2-HOPO-MSLN-mAb and [89Zr]Zr-DFO-MSLN-mAb were evaluated in vitro to determine binding affinity and immunoreactivity in HT29-MSLN and PDX (NCI-Meso16, NCI-Meso21) cells. For both the zirconium-89 conjugates, in vivo studies (biodistribution/imaging) were performed at days 1, 3, and 6, from which tissue uptake was determined. Results Both the conjugates demonstrated a low nanomolar binding affinity for MSLN and >95% immunoreactivity. In all the three tumor types, biodistribution of [89Zr]Zr-DFO-MSLN-mAb resulted in higher tumor uptake(15.88-28-33%ID/g) at all time points compared with [89Zr]Zr-3,2-HOPO-MSLN-mAb(7-13.07%ID/g). [89Zr]Zr-3,2-HOPO-MSLN-mAb femur uptake was always higher than [89Zr]Zr-DFO-MSLN-mAb, and imaging results concurred with the biodistribution studies. Conclusions Even though the conjugates exhibited a high binding affinity for MSLN, [89Zr]Zr-DFO-MSLN-mAb showed a higher tumor and lower femur uptake than [89Zr]Zr-3,2-HOPO-MSLN-mAb. Nevertheless, [89Zr]Zr-3,2-HOPO-MSLN-mAb could be used to study organ distribution and lesion uptake with the caveat of detecting MSLN-positive bone lesions. Clinical trial (NCT03507452).Objectives. To identify factors that influence when people who use drugs (PWUDs) call 911 for an overdose.Methods. We conducted 45 qualitative interviews and 180 surveys with PWUDs who had recently witnessed overdoses in Southern California from 2017 to 2019. We used conditional inference tree and random forest models to generate and validate a model to predict whether 911 would be called.Results. Our model had good in- (83%) and out-of-sample (84%) predictive accuracy. Three aspects of the social and policy environment influenced calling 911 for an overdose the effectiveness of response strategies employed, the behavior of other bystanders, and whether the responder believes it is their responsibility to call.Conclusions. Even in the presence of policies that provide some protections, PWUDs are faced with difficult decisions about calling 911 and must weigh their own safety against that of an overdose victim. Potential interventions include strengthening training and safety planning for PWUDs, bolstering protections for PWUDs when they call 911, and separating law enforcement response from emergency medical response to overdoses.
