Associations of Local Cannabis Control Policies With Harmful Cannabis Exposures Reported to the California Poison Control System.

BACKGROUND: Cannabis exposures reported to the California Poison Control System increased following the initiation of recreational cannabis sales on 1 January 2018 (i.e., "commercialization"). We evaluated whether local cannabis control policies adopted by 2021 were associated with shifts in harmful cannabis exposures. METHODS: Using cannabis control policies collected for all 539 California cities and counties in 2020-2021, we applied a differences-in-differences design with negative binomial regression to test the association of policies with harmful cannabis exposures reported to California Poison Control System (2011-2020), before and after commercialization. We considered three policy categories: bans on storefront recreational retail cannabis businesses, overall restrictiveness, and specific recommended provisions (restricting product types or potency, packaging and labeling restrictions, and server training requirements). RESULTS: Localities that ultimately banned storefront recreational retail cannabis businesses had fewer harmful cannabis exposures for children aged <13 years (rate ratio = 0.82; 95% confidence interval = 0.65, 1.02), but not for people aged >13 years (rate ratio = 0.97; 95% confidence interval = 0.85, 1.11). Of 167 localities ultimately permitting recreational cannabis sales, overall restrictiveness was not associated with harmful cannabis exposures among children aged <13 years, but for people aged >13 years, a 1-standard deviation increase in ultimate restrictiveness was associated with fewer harmful cannabis exposures (rate ratio = 0.93; 95% confidence interval = 0.86, 1.01). For recommended provisions, estimates were generally too imprecise to detect associations with harmful cannabis exposures. CONCLUSION: Bans on storefront retail and other restrictive approaches to regulating recreational cannabis may be associated with fewer harmful cannabis exposures for some age groups following statewide commercialization.

Enhancing immigrant families' mental health through the promotion of structural and community-based support.

Immigrant communities in the United States are diverse and have many assets. Yet, they often experience stressors that can undermine the mental health of residents. To fully promote mental health and well-being among immigrant communities, it is important to emphasize population-level policies and practices that may serve to mitigate stress and prevent mental health disorders. In this paper, we describe the stressors and stress experienced by immigrant families, using Sunset Park, Brooklyn as an example. We discuss ways to build structures and policies in support of equitable environments that promote mental health at the population level and enable families and their children to thrive.

Did a workplace sugar-sweetened beverage sales ban reduce anxiety-related sugar-sweetened beverage consumption during the COVID-19 pandemic?

OBJECTIVE: Workplace sugar-sweetened beverage (SSB) sales bans can reduce SSB consumption. Because stress and anxiety can promote sugar consumption, we examined whether anxiety among hospital employees during the COVID-19 pandemic was associated with changes in SSB consumption and explored whether this relationship varied by exposure to a workplace SSB sales ban. DESIGN: In a prospective, controlled trial of workplace SSB sales bans, we examined self-reported anxiety (generalised anxiety disorder-7) and self-reported SSB consumption (fluid ounces/d) before (July 2019) and during (May 2020) the COVID-19 pandemic. SETTING: Hospital sites in two conditions (four with SSB sales bans and three without sales bans) in Northern California. PARTICIPANTS: We sampled 580 participants (hospital employees) from a larger trial of sales bans; all were regular consumers of SSB (minimum 3/week at main trial enrollment). This subsample was chosen based on having appropriately timed data for our study questions. RESULTS: Across conditions, participants reduced SSB consumption over the study period. However, participants with higher pandemic-era anxiety scores experienced smaller reductions in SSB consumption after 9 months compared with those with lower anxiety scores (ß = 0·65, P < 0·05). When the sample was disaggregated by sales ban condition, this relationship held for participants in the control group (access to SSB at work, ß = 0·82, P < 0·05), but not for those exposed to an SSB sales ban (ß = 0·42, P = 0·25). CONCLUSIONS: SSB sales bans likely reduce SSB consumption through multiple pathways; buffering stress-related consumption may be one mechanism.

Bringing competency-based communication training to scale: A multi-institutional virtual simulation-based mastery learning curriculum for Emergency Medicine residents.

PURPOSE: Serious illness communication skills are essential for physicians, yet competency-based training is lacking. We address scalability barriers to competency-based communication skills training by assessing the feasibility of a multi-center, virtual simulation-based mastery learning (vSBML) curriculum on breaking bad news (BBN). METHODS: First-year emergency medicine residents at three academic medical centers participated in the virtual curriculum. Participants completed a pretest with a standardized patient (SP), a workshop with didactics and small group roleplay with SPs, a posttest with an SP, and additional deliberate practice sessions if needed to achieve the minimum passing standard (MPS). Participants were assessed using a previously published BBN assessment tool that included a checklist and scaled items. Authors compared pre- and posttests to evaluate the impact of the curriculum. RESULTS: Twenty-eight (90%) of 31 eligible residents completed the curriculum. Eighty-nine percent of participants did not meet the MPS at pretest. Post-intervention, there was a statistically significant improvement in checklist performance (Median= 93% vs. 53%, p < 0.001) and on all scaled items assessing quality of communication. All participants ultimately achieved the MPS. CONCLUSIONS: A multi-site vSBML curriculum brought all participants to mastery in the core communication skill of BBN and represents a feasible, scalable model to incorporate competency-based communication skills education in a widespread manner.

Lightness constancy in reality, in virtual reality, and on flat-panel displays.

Virtual reality (VR) displays are being used in an increasingly wide range of applications. However, previous work shows that viewers often perceive scene properties very differently in real and virtual environments and so realistic perception of virtual stimuli should always be a carefully tested conclusion, not an assumption. One important property for realistic scene perception is surface color. To evaluate how well virtual platforms support realistic perception of achromatic surface color, we assessed lightness constancy in a physical apparatus with real lights and surfaces, in a commercial VR headset, and on a traditional flat-panel display. We found that lightness constancy was good in all three environments, though significantly better in the real environment than on the flat-panel display. We also found that variability across observers was significantly greater in VR and on the flat-panel display than in the physical environment. We conclude that these discrepancies should be taken into account in applications where realistic perception is critical but also that in many cases VR can be used as a flexible alternative to flat-panel displays and a reasonable proxy for real environments.

Phytonutritional Composition and Antioxidant Properties of Southern African, Purple-Fleshed Sweet Potato (Ipomoea batatas (L.) Lam.) Storage Roots.

Purple sweet potatoes (Ipomoea batatas (L.) genotype) in Southern Africa have a phytonutritional composition and antioxidant properties that can increase incomes and improve nutrition. This study compared the phytonutrient composition and antioxidant properties of four purple-colour sweet potato genotypes (local Purple-purple, '2019-1-1', and USA genotypes, '08-21P' and '16-283P'). These purple sweet potato genotypes were characterised by UPLC/QTOF/MS and 16 phenolic compounds were identified. Purple-purple (very dark purple) showed the highest concentration of cyanidins and peonidin derivatives. Chlorogenic acid derivatives were highest in the genotype '16-283P'. 'Puple-purple' and '16-283P' displayed the strongest antioxidant power and scavenging activities. Diaffeoylquinic acid isomer 1 was identified as the marker candidate for distinguishing the four purple sweet potato genotypes. Southern Africa's highest-protein sweet potato genotypes are Purple-purple (28.81 g/100 g) and '08-21 P' (24.31 g/100 g). A 13.65 g portion of '2019-1-1' would meet the Recommended Dietary Allowance (RDA) for iron for men, while 25.59 g would meet the RDA for children, and 30.72 g would meet the RDA for women. The sweet potato root of genotype '2019-1-1' provides 31.43 g of Zn per day for children and 22.86 g for adults. The roots of local cultivar Purple-purple can be used as functional food ingredients.

Transcriptional and phenotypic heterogeneity underpinning venetoclax resistance in AML.

The venetoclax BCL2 inhibitor in combination with hypomethylating agents represents a cornerstone of induction therapy for older AML patients, unfit for intensive chemotherapy. Like other targeted therapies, venetoclax-based therapies suffer from innate and acquired resistance. While several mechanisms of resistance have been identified, the heterogeneity of resistance mechanism across patient populations is poorly understood. Here we utilized integrative analysis of transcriptomic and ex-vivo drug response data in AML patients to identify four transcriptionally distinct VEN resistant clusters (VR_C1-4), with distinct phenotypic, genetic and drug response patterns. VR_C1 was characterized by enrichment for differentiated monocytic- and cDC-like blasts, transcriptional activation of PI3K-AKT-mTOR signaling axis, and energy metabolism pathways. They showed sensitivity to mTOR and CDK inhibition. VR_C2 was enriched for NRAS mutations and associated with distinctive transcriptional suppression of HOX expression. VR_C3 was characterized by enrichment for TP53 mutations and higher infiltration by cytotoxic T cells. This cluster showed transcriptional expression of erythroid markers, suggesting tumor cells mimicking erythroid differentiation, activation of JAK-STAT signaling, and sensitivity to JAK inhibition, which in a subset of cases synergized with venetoclax. VR_C4 shared transcriptional similarities with venetoclax-sensitive patients, with modest over-expression of interferon signaling. They were also characterized by high rates of DNMT3A mutations. Finally, we projected venetoclax-resistance states onto single cells profiled from a patient who relapsed under venetoclax therapy capturing multiple resistance states in the tumor and shifts in their abundance under venetoclax selection, suggesting that single tumors may consist of cells mimicking multiple VR_Cs contributing to intra-tumor heterogeneity. Taken together, our results provide a strategy to evaluate inter- and intra-tumor heterogeneity of venetoclax resistance mechanisms and provide insights into approaches to navigate further management of patients who failed therapy with BCL2 inhibitors.

Ecological sound loudness in environmental sound representations.

Listeners recognizing environmental sounds must contend with variations in level due to the source level and the environment. Nonetheless, variations in level disrupt short-term sound recognition [Susini, Houix, Seropian, and Lemaitre (2019). J. Acoust. Soc. Am. 146(2), EL172-EL176] suggesting that loudness is encoded. We asked whether the experimental custom of setting sounds to equal levels disrupts long-term recognition, especially if it creates a mismatch with ecological loudness. Environmental sounds were played at equalized or ecological levels. Although recognition improved with increased loudness and familiarity, this relationship was unaffected by equalization or real-life experience with the source. However, sound pleasantness was altered by deviations from the ecological level.

Stage based recipient and donor outcome in twin-to-twin transfusion syndrome treated by fetoscopic laser surgery using Solomon technique.

OBJECTIVE: To evaluate twin survival stratified by Quintero stage in patients with twin-to-twin transfusion syndrome (TTTS) after Solomon laser treatment. METHODS: Single center cohort of consecutive twin pregnancies treated with Solomon laser for TTTS. Preoperative Quintero stage, perioperative characteristics and obstetric factors were related to neonatal survival of the recipient and donor at discharge. Determinants of twin survival were evaluated using univariate, logistic regression and cumulative survival probability analyses. RESULTS: Of 402 twins with TTTS, 80 (19.9%) had stage I, 126 (31.3%) stage II, 169 (42%) stage III and 27 (6.7%) stage IV. Post laser TAPS or recurrent TTTS occurred in 19 (4.7%) patients and 11 (2.7%) required repeat laser. Preterm premature rupture of membranes occurred in 150 (37.3%) patients and median gestational age of delivery 32+1 weeks. In 303 (75.4%) both twins were alive at discharge; [66 (82.5%) in stage I, 101 (80.2%) in stage II, 114 (67.5%) in stage III and 22 (81.5%) in stage IV, p=0.062]. Compared to recipients, donor survival was only lower in stage III (155 (91.7%) recipients vs 118 (69.8%) donors, Chi square 24.685, p<0.0001). Larger intertwin size discordance and umbilical artery (UA) end-diastolic velocity (EDV) determined donor demise (Nagelkerke R2 0.38, P<0.001). Overall, spontaneous post laser donor demise accounted for the majority (39.5%) of all losses. Cumulative donor survival decreased from 92% to 65% with size discordance >30% and 48% when UA EDV was absent (p<0.001). CONCLUSION: Solomon laser achieves TTTS resolution and double survival in a high proportion of cases. Recipient and donor survival is comparable unless there is significant size discordance and placental dysfunction. This degree of unequal placental sharing, typically found in stage III, is the primary factor preventing double survival due to a higher rate of donor demise. This article is protected by copyright.

The Need for Responsive Workforce Development During the Pandemic and Beyond: A Case Study of the Regional Public Health Training Centers.

CONTEXT: The COVID-19 pandemic underscored the importance of a strong public health infrastructure for protecting and supporting the health of communities. This includes ensuring an adaptive workforce capable of leading through rapidly changing circumstances, communicating effectively, and applying systems thinking to leverage cross-sector partnerships that help promote health equity. The 10 Regional Public Health Training Centers (PHTCs) advance the capacity of the current and future public health workforce through skill development and technical assistance in these and other strategic areas. PROGRAM: This study examines activities through which the Regional PHTCs and their partners supported the public health workforce during the pandemic. Representatives of the 10 Regional PHTCs completed a survey in the spring of 2022. The survey included (1) pulling trends in training usage from 2018-2021 annual performance reports and (2) questions assessing the type, content, and reach of training needs assessments, training and technical assistance, student placements, and PHTC Network collaborative activities that occurred from January 1, 2020, to December 31, 2021. Respondents also reflected on trends in use, challenges, lessons learned, stories of impact, and future PHTC practice. EVALUATION: During the pandemic, the Regional PHTCs engaged in numerous efforts to assess needs, provide training and technical assistance to the practice community, facilitate projects that built student competency to support public health agency efforts, and collaborate as the PHTC Network on national-level initiatives. Across these activities, the Regional PHTCs adjusted their approaches and learned from each other in order to meet regional needs. DISCUSSION: The Regional PHTCs provided student and professional development in foundational public health knowledge and skills within their regions and nationally while being flexible and responsive to the changing needs of the field during the pandemic. Our study highlights opportunities for collaboration and adaptive approaches to public health workforce development in a postpandemic environment.

Genomics education for advance practice nurses: Staying cutting edge.

ABSTRACT: As we celebrate the 20th anniversary of sequencing of the human genome and the rapid integration of genetics in health care, we pause to reflect on the status of genomic competency in nursing. The literature provides evidence that nurses do not feel prepared or confident in genomics. Genomic education for nurses and other health care professionals can support access and equity in the integration of genomics into practice. Resources are provided to support genomic education and clinical support.

Risk profiles and incidence of cardiovascular events across different cancer types.

BACKGROUND: Cancer survivors are at increased risk for cardiovascular (CV) disease, although additional data are needed to better understand the incidence of CV events across different malignancies. This study sought to characterize the incidence of major adverse CV events [myocardial infarction, stroke, unstable angina (MACE), or heart failure (HF)] across multiple cancer types after cancer diagnosis. PATIENTS AND METHODS: Patients were identified from a USA-based administrative claims database who had index cancer diagnoses of breast, lung, prostate, melanoma, myeloma, kidney, colorectal, leukemia, or lymphoma between 2011 and 2019, with continuous enrollment for ≥12 months before diagnosis. Baseline CV risk factors and incidence rates of CV events post-index were identified for each cancer. Multivariable Cox hazards models assessed the cumulative incidence of MACE, accounting for baseline risk factors. RESULTS: Among 839 934 patients across nine cancer types, CV risk factors were prevalent. The cumulative incidence of MACE was highest in lung cancer and myeloma, and lowest in breast cancer, prostate cancer, and melanoma. MACE cumulative incidence for lung cancer was 26% by 4 years (2.7-fold higher relative to breast cancer). The incidence of stroke was especially pronounced in lung cancer, while HF was highest in myeloma and lung cancer. CONCLUSIONS: CV events were especially increased following certain cancer diagnoses, even after accounting for baseline risk factors. Understanding the variable patient characteristics and associated CV events across different cancers can help target appropriate CV risk factor modification and develop strategies to minimize adverse CV events and improve patient outcomes.

Perceiving depth and motion in depth from successive occlusion.

Occlusion, or interposition, is one of the strongest and best-known pictorial cues to depth. Furthermore, the successive occlusions of previous objects by newly presented objects produces an impression of increasing depth. Although the perceived motion associated with this illusion has been studied, the depth percept has not. To investigate, participants were presented with two piles of disks with one always static and the other either a static pile or a stacking pile where a new disk was added every 200 ms. We found static piles with equal number of disks appeared equal in height. In contrast, the successive presentation of disks in the stacking condition appeared to enhance the perceived height of the stack-fewer disks were needed to match the static pile. Surprisingly, participants were also more precise when comparing stacking versus static piles of disks. Reversing the stacking by removing rather than adding disks reversed the bias and degraded precision. In follow-up experiments, we used nonoverlapping static and dynamic configurations to show that the effects are not due to simple differences in perceived numerosity. In sum, our results show that successive occlusions generate a greater sense of height than occlusion alone, and we posit that dynamic occlusion may be an underappreciated source of depth information.

Evolution of antiseizure medication use and cost in the United States of America 2006-2021.

OBJECTIVE: To describe the evolution in use and cost of antiseizure medications (ASM) in the United States of America (USA). METHODS: Retrospective descriptive study using the IBM MarketScan Commercial Database (data of privately-insured patients) for the years 2006 to 2021. We identified patients with epilepsy who were on ASM. We adjusted cost for inflation with the Gross Domestic Product Implicit Price Deflator. RESULTS: We evaluated 347,158 patients (46.9 % males; median (p25-p75) age: 33 (17-49) years; 28 % with pediatric-onset epilepsy and 72 % with adult-onset epilepsy) with a total of 1,385,382 person-years and 588,285,065 ASM prescription days. The most commonly prescribed (as percentage of prescription days) ASMs in 2006 were valproate (18 %) and lamotrigine (17 %) in pediatric-onset epilepsy and phenytoin (21 %) and carbamazepine (17 %) in adult-onset epilepsy, but starting in the 2010s, levetiracetam and lamotrigine became the most commonly prescribed ASMs in both pediatric-onset (in 2021, levetiracetam 25 %, lamotrigine 16 %) and adult-onset (in 2021, levetiracetam 27 %, lamotrigine 20 %) epilepsy. The proportion of generic ASM use increased 3.6-fold: from 23 % of prescription days in 2006 to 83 % of prescription days in 2021. The median (p25-p75) average wholesale price (AWP) per person-year increased by 102 % from $2,684 ($990-$5,509) in 2006 to $5,417 ($2,858-$12,310) in 2021. The increases were greater in absolute terms for brand-name ASMs by 419 %: $3,109 ($1,564-$5,068 in 2006 and $16,149 ($12,950-$23,377) in 2021 than for generic ASMs by 462 %: $699 ($457-$1,678) in 2006 and $3,931 ($2,618-$6,081) in 2021. The costs directly borne by the patient (copay, coinsurance, deductibles, and pharmacy processing fees) increased by 69 % for brand-name ASMs from $393 ($246-$570) in 2006 to $665 ($335-$1,308) in 2021, but decreased by 37 % for generic ASMs from $147 ($98-$213) in 2006 to $92 ($51-$141) in 2021. CONCLUSIONS: The median cost of ASMs per person-year approximately doubled from 2006 to 2021. The increase in use of generic ASMs probably helped buffer the growing costs of ASMs. However, generic ASMs already represent 83 % of prescription days in 2021, with limited room to further contain costs by just increasing the proportion of generics.

Researcher-Practitioner Partnerships to Implement and Evaluate Sexual and Relationship Violence Prevention Programs for Boys and Men.

Although male-focused sexual and relationship violence (SRV) prevention programs are widely promulgated, limited guidance concerning how programs should be implemented for rigorous evaluation exists. To help develop evidence for such guidance, this paper reports on 20 interviews with leaders at youth-serving community-based organizations (CBOs) and educational institutions, which are sites for male-focused SRV prevention programs. This study examined: (1) how programs can be designed to engage male participants; and (2) how youth-serving CBOs and educational institutions can partner with researchers for evaluations. Findings underscore the importance of attending to the unique needs of program participants, their parents/guardians, and host organizations.

Controlled trial of a workplace sales ban on sugar-sweetened beverages.

OBJECTIVE: To examine the effectiveness of a workplace sugar-sweetened beverage (SSB) sales ban on reducing SSB consumption in employees, including those with cardiometabolic disease risk factors. DESIGN: A controlled trial of ethnically diverse, full-time employees who consumed SSB heavily (sales ban n 315; control n 342). Outcomes included standardised measures of change in SSB consumption in the workplace (primary) and at home between baseline and 6 months post-sales ban. SETTING: Sutter Health, a large non-profit healthcare delivery system in Northern California. PARTICIPANTS: Full-time employees at Sutter Health screened for heavy SSB consumption. RESULTS: Participants were 66·1 % non-White. On average, participants consumed 34·7 ounces (about 1 litre) of SSB per d, and the majority had an elevated baseline BMI (mean = 29·5). In adjusted regression analyses, those exposed to a workplace SSB sales ban for 6 months consumed 2·7 (95 % CI -4·9, -0·5) fewer ounces of SSB per d while at work, and 4·3 (95 % CI -8·4, -0·2) fewer total ounces per d, compared to controls. Sales ban participants with an elevated BMI or waist circumference had greater post-intervention reductions in workplace SSB consumption. CONCLUSIONS: Workplace sales bans can reduce SSB consumption in ethnically diverse employee populations, including those at higher risk for cardiometabolic disease.
