RESUMEN

PURPOSE: To compare early visual quality of small incision lenticule extraction (SMILE) versus laser in situ keratomileusis (LASIK) in terms of low contrast acuity. METHODS: A secondary analysis was performed using a harmonized dataset derived from two completed prospective cohort studies on active-duty military service members undergoing either SMILE (n = 37), wavefront-guided (WFG) LASIK (n = 51), or wavefront-optimized (WFO) LASIK (n = 56). Night vision and photopic and mesopic low contrast visual acuity (LCVA) up to 3 months postoperatively were compared between groups. RESULTS: Compared to SMILE-treated eyes, WFG LASIK-treated eyes had significantly better night vision and photopic LCVA at 1 month postoperatively (beta = -0.039, P = .016; beta = -0.043, P = .007, respectively). WFO LASIK-treated eyes had significantly better photopic LCVA at 1 month postoperatively (beta = -0.039, P = .012) but had worse mesopic LCVA at 3 months postoperatively (beta = 0.033, P = .015) versus SMILE-treated eyes. CONCLUSIONS: SMILE and LASIK, on either a WFG or WFO laser platform, yielded excellent outcomes, but LCVA seemed to recover quicker following LASIK compared to SMILE.

RESUMEN

The present article addresses claims commonly made by prosecution witnesses in sexual assault trials: that attention narrows under stress, and that these attended aspects of the event are encoded in a way that ensures accuracy and resistance to fading and distortion. We provide evidence to contradict such claims. Given that what is encoded is largely the gist of one's interpretation of experience, we discuss the way in which attention and emotion can bias the interpretation of experience. We illustrate with issues of memory reports in cases of acquaintance rape, where the primary issue is the presence or absence of consent. We provide some specific illustrations concerning effects of emotion on interpretation of sexual consent. Finally, based on what is known regarding priming effects on memory retrieval and judgment, we conclude with discussion of the potential of some "trauma-informed" interviewing strategies to promote false memories (such as FETI: Forensic Experiential Trauma Interview).

RESUMEN

BACKGROUND: Terms such as 'natural', 'organic' and 'tobacco and water' on cigarette packs may communicate misleading reduced harm messages to consumers. This study describes sales volume and price for brands that used these misleading descriptors in the USA by year, brand and state. METHODS: The data come from Information Resources Incorporated sales data collected in 44 US states from January 2018 to January 2023. Trained coders used Universal Product Codes, purchased packs and internet searches to identify cigarettes sold with 'natural', 'organic' and 'tobacco and water' on packs. We report cigarette pack unit sales counts (sales volume) and average price per pack by year, as well as per cent year-over-year change in sales volume and price and annual market share by descriptor terms. RESULTS: Overall, pack sales volume decreased year-over-year from 2019 to 2022. Sales volume for packs with 'natural', 'tobacco and water' and 'organic' decreased less than overall; in some cases, they increased. In 2022, packs with 'natural' accounted for the greatest share of cigarette unit sales (5.42% or 33 605 036 packs), followed by 'tobacco and water' (2.25% or 12 959 905 packs) and 'organic' (0.53% or 4 614 592 packs). Natural American Spirit (NAS) and Winston accounted for most sales with 'natural' and 'tobacco and water'; NAS accounted for nearly all sales with 'organic'. Packs with 'natural', 'tobacco and water' or 'organic' made up the largest portion of sales in western (Oregon, Idaho, California, Colorado and Washington) and northeastern (Vermont, Massachusetts and New Hampshire) US states. CONCLUSION: Brands using 'natural', 'tobacco and water' and 'organic' on packs increased their market share between 2019 and 2022; in some states, market share was over 10% in 2022. Our findings emphasise the importance of regulating these terms and continually monitoring their population impact.
