Tobacco price promotions may prompt tobacco trials among youth. We assessed whether receiving price promotions for any tobacco, cigarettes, e-cigarettes and cigars was associated with product use progression.

The analysis included a nationally representative sample of youth never tobacco users (aged 12-16; n=9405) from wave 4 (2016-2018) of the Population Assessment of Tobacco and Health Study. We assessed past-year receipt of price promotions and use progression (initiation, current use and ever regular use) for any tobacco, cigarettes, e-cigarettes and cigars 1 year later at wave 4.5 (2017-2018). Multivariable logistic regressions were used to examine the associations between receiving price promotions and use progression by product type, controlling for covariates.

At wave 4.5, 9.4% of youth initiated any tobacco (1.8%, 7.8% and 0.9% for cigarettes, e-cigarettes and cigars), and 5.4% received any price promotions (3.8%, 3.1% and 0.9% for cigarettes, e-cigarettes and cigars). Receiving any tobacco pri tactics.
To understand the impact of e-cigarette devices, flavours, nicotine levels and prices on adult e-cigarette users' choices among closed-system and open-system e-cigarettes, cigarettes and heated tobacco products (HTPs).

Online discrete choice experiments were conducted among adult (≥18 years) e-cigarette users (n=2642) in August 2020. Conditional logit regressions were used to assess the relative impact of product attributes and the interactions between product attributes and user characteristics, with stratified analyses to examine differences by smoking status and primarily used e-cigarette device and flavour.

On average, participants preferred non-tobacco and non-menthol flavours most, preferred open-system over closed-system e-cigarettes and preferred regular nicotine level over low nicotine level. However, the preference varied by demographics, smoking status and the primarily used e-cigarette device and flavour. The differences in preference among products/devices were larger than the difference amtes. Intervention strategies should be tailored to specific groups.
Residency is an important time for career planning. Little is known about how trainees make career decisions during this formative period.

The objective of this study was to understand whether 'design thinking' activities help to inform Internal Medicine-Paediatrics (Med-Peds) residents' career decisions.

We performed a cross-sectional survey of a national sample of fourth-year Med-Peds residents in May-July 2019 covering intended career, helpfulness of 'life design' strategies used to inform career decision and confidence with intended career plans. Bivariate analyses were performed to evaluate associations between used strategies and confidence with career plans.

A total of 86/145 (59%) of residents responded to the survey. The most helpful activities for clarifying career decisions were immersive exposure to the career during residency, and reflecting on compatibility of careers with their views of life and work. Finding the right mentor was associated with higher confidence in one's intended career path (p<0.05). There were no significant differences with confidence in intended career plan by gender or career path. Career decisions made during the first 2 years of residency were associated with higher confidence than those made prior to or in the second half of residency (p=0.01 and p=0.004).

This national survey of graduating Med-Peds residents reveals that proactive life design strategies were helpful in bringing clarity to their decision and were associated with higher confidence in intended career plans. These data should be of interest to residency training programmes in their efforts to support trainees with their career decisions.

Cortical inhibitory interneurons arise in the ventral telencephalon and migrate tangentially forming three transient migratory streams in the cortex before reaching their final laminar destination. Although migration defects lead to the disruption of inhibitory circuits and are linked to aspects of psychiatric disorders such as autism and schizophrenia, the molecular mechanisms controlling cortical interneuron development and final layer positioning are incompletely understood. Here we show that mouse embryos with a double deletion of FLRT2 and FLRT3 genes encoding cell adhesion molecules, exhibit an abnormal distribution of interneurons within the streams during development, which in turn, affect the layering of somatostatin+ interneurons postnatally. Mechanistically, FLRT2 and FLRT3 proteins act in a non cell-autonomous manner, possibly ins are required for the proper distribution of interneurons within the cortical migratory streams and for their final laminar allocation in the postnatal cortex. These results expand the multifunctional role of FLRTs during nervous system development besides their role in axon guidance and the migration of excitatory cortical neurons.Aging, disease and trauma can lead to loss of vestibular hair cells and permanent vestibular dysfunction. Idasanutlin supplier Previous work showed that, following acute destruction of ∼95% of vestibular hair cells in adult mice, ∼20% regenerate naturally (without exogenous factors) through supporting cell transdifferentiation. There is, however, no evidence for recovery of vestibular function. To gain insight into the lack of functional recovery, we assessed functional differentiation in regenerated hair cells for up to 15 months, focusing on key stages in stimulus transduction and transmission hair bundles, voltage-gated conductances, and synaptic contacts. Regenerated hair cells had many features of mature type II vestibular hair cells, including polarized mechanosensitive hair bundles with zone-appropriate stereocilia heights, large voltage-gated potassium currents, basolateral processes, and afferent and efferent synapses. Regeneration failed, however, to recapture the full range of properties of normal populations, and many regenerated hair cells had some properties of immature hair cells, including small transduction currents, voltage-gated sodium currents and small or absent HCN currents.
