RESUMO
Eye injuries from sports, activities, and work are a leading cause of vision loss in youth. Most eye injuries can be prevented with protective eyewear. An open-ended survey on youth perspectives on eye trauma and protection was administered to the MyVoice Text Message Cohort of US youth ages 14-24 years. Qualitative, text message responses were coded using thematic analysis. The survey was distributed to 798 recipients; 641 (80.3%) responded. Many youth were concerned about the impact of excessive screen use (n = 278 [43.8%]) and sunlight or UV exposure (n = 239 [37.6%]) on their eye health. Fewer were concerned about injury from sports and activities (n = 115 [18.1%]) or job-related eye risks (n = 77 [12.1%]). The most common actions that youth took to protect their eyes included sun protection (eg, sunglasses; n = 300 [47.2%]), refractive correction (eg, glasses, contacts; n = 195 [30.7%]) and screen protection (eg, blue light blocking glasses; n = 159 [25.0%]). Fewer wore eye protection for sports or activities (n = 54 [8.5%]) or work (n = 41 [6.5%]). Youth concerns about eye injury from screens and sunlight are misaligned with the main causes of vision loss in this population, suggesting that public health education is needed to promote optimal eye safety.

BACKGROUND: People with low income are disproportionately affected by type 2 diabetes (T2D), and 17.6% of US adults with T2D experience food insecurity and low diet quality. Low-carbohydrate eating plans can improve glycemic control, promote weight loss, and are associated with improved cardiometabolic health and all-cause mortality. Little is known about supporting low-carbohydrate eating for people with T2D, although food-as-medicine interventions paired with nutrition education offer a promising solution. OBJECTIVE: This program aims to support the initiation of dietary changes by using grocery delivery and low-carbohydrate education to increase the quality of low-carbohydrate nutrition among people with T2D and food insecurity. METHODS: This program was a nonrandomized pilot conducted at 21 primary care practices in Michigan. Adults with T2D and food insecurity or low income were eligible to enroll. Patients were referred by primary care clinic staff. All participants received the 3-month program, which included monthly US $80 credits for healthy foods, free grocery delivery from Shipt, and low-carbohydrate nutrition education. Food credits were restricted to the purchase of healthy foods. Education materials, developed in collaboration with providers and patients, included print, digital, interactive web, and video formats. At enrollment, participants completed a survey including demographics, diabetes health, diet and physical activity, and diabetes management and knowledge. After the 3-month program, participants completed a survey with repeat assessments of diabetes health, diet and physical activity, and diabetes management and knowledge. Perspectives on participant experience and perceived program impact, food purchasing behaviors, and use of educational materials were also collected. Diabetes health information was supplemented with data from participant medical records. We plan to perform mixed methods analysis to assess program feasibility, acceptability, and impact. Primary quality improvement (QI) measures are the number of patients referred and enrolled, use of US $80 food credits, analysis of food purchasing behavior, participant experience with the program, and program costs. Secondary QI measures include changes in hemoglobin A1c, weight, medications, self-efficacy, diabetes and carbohydrate knowledge, and activity between baseline and follow-up. RESULTS: This program started in October 2022. Data collection is expected to be concluded in June 2024. A total of 151 patients were referred to the program, and 83 (55%) were enrolled. The average age was 57 (SD 13; range 18-86) years, 72% (57/79) were female, 90% (70/78) were White, and 96% (74/77) were of non-Hispanic ethnicity. All participants successfully ordered grocery delivery during the program. CONCLUSIONS: This pilot QI program aimed to improve diet quality among people with T2D and food insecurity by using grocery delivery and low-carbohydrate nutrition education. Our findings may help inform the implementation of future QI programs and research studies on food-as-medicine interventions that include grocery delivery and education for people with T2D.

Purpose: We aimed to understand adolescents' and young adults' perceptions and the extent of their knowledge about breastfeeding. Methods: Participants (adolescents and young adults in the United States, 14-24 years of age) were texted five open-ended questions about their perceptions of various aspects of breastfeeding including their initial reaction to breastfeeding, the impact on the infant and parent, how it compares with formula, and whether they were breastfed. The responses were analyzed for themes using an inductive content analysis approach. Responses were compared using χ2 tests to assess if knowledge and education about breastfeeding differed according to gender identity and age. Results: Among 1,283 participants, 829 responded (response rate = 64.4%). The average age was 18.8 (standard deviation [SD] = 2.9), with 53% female and 10% Black. Most adolescents and young adults understand there are health benefits of breastfeeding for the breastfeeding dyad (n = 589; 78.8%), yet also indicate an awareness of negative aspects (n = 256; 36.1%). Participants who identified as female or gender-variant and those who were older were more likely to refer to the emotional and bonding connections breastfeeding creates (p = 0.0011 and p = 0.0002). Males were more likely to have less knowledge about breastfeeding effects on the breastfeeding person but have more negative attitudes toward formula (p = 0.0298 and p = 0.0543). Younger respondents tended to indicate that formula was better than breast milk (p = 0.0534). Conclusion: We found a mix of positive and negative perceptions of breastfeeding among adolescents and young adults. Understanding how youth view breastfeeding can inform targeted education for this population that includes all genders and can begin before pregnancy.

BACKGROUND: Metastatic melanoma to the small bowel is an aggressive disease often accompanied by obstruction, abdominal pain, and gastrointestinal bleeding. With advancements in melanoma treatment, the role for metastasectomy continues to evolve. Inclusion of novel immunotherapeutic agents, such as checkpoint inhibitors, into standard treatment regimens presents potential survival benefits for patients receiving metastasectomy. CASE PRESENTATION: We report an institutional experience of 15 patients (12 male, 3 female) between 2014-2022 that underwent small bowel metastasectomy for metastatic melanoma and received perioperative systemic treatment. Median age of patients was 64 years (range: 35-83 years). No patients died within 30 days of their surgery, and the median hospital length of stay was 5 days. Median overall survival in these patients was 30.1 months (range: 2-115 months). Five patients died from disease (67 days, 252 days, 426 days, 572 days, 692 days postoperatively), one patient died of non-disease related causes (1312 days postoperatively), six patients are alive with disease, and three remain disease free. CONCLUSIONS: This case series presents an updated perspective of the utility of metastasectomy for small bowel metastasis in the age of novel immunotherapeutic agents as standard systemic treatment. Small bowel metastasectomy for advanced melanoma performed in conjunction with perioperative systemic therapy is safe and appears to promote long-term survival and enhanced quality of life.

PURPOSE: Period poverty is the lack of accessible menstrual education or menstrual tools. Millions of women and girls around the world experience period poverty, which can contribute to disparities in school and work performance, as well as overall quality of life. However, not much is known about youth experiences and perceptions of period poverty. This study aims to understand the personal experiences and opinions of American youth regarding knowledge about menstruation and period poverty, as well as to gauge youth attitudes of existing and future period poverty initiatives. METHODS: The MyVoice nationwide text message poll was used to ask five open-ended questions to over 1,000 youth across the United States aged 14-24 years. Responses were analyzed using content analysis by two independent researchers, and differences in coding were reviewed and resolved by discussion. RESULTS: Overall, 963 youth (80%) responded, and the sample was 54.7% self-reported male with an average age of 20.1 years (standard deviation = 2.3). Three main themes emerged: 1. Most youth, regardless of self-reported gender, have had conversations about periods but comfort discussing the topic varies, 2. Youths' knowledge of menstruation varies with personal experience, or lack thereof, and 3. Some youth have experience with period poverty, and most are overwhelmingly supportive of policies to improve access to period products. DISCUSSION: These findings suggest that normalization of discussions of menstruation, increasing awareness of the prevalence and impacts of period poverty, and greater implementation of programs to mitigate period poverty are supported by youth, and may reduce period poverty in the United States.

BACKGROUND: Diet intervention forms the cornerstone for cardiovascular disease (CVD) management. OBJECTIVE: The objective was to measure the frequency of dietary counseling documentation for patients recently hospitalized with CVD. DESIGN: This was an observational study. PARTICIPANTS AND SETTING: Patients were included from the Michigan Value Collaborative Multipayer Claims Registry from October 2015 to February 2020. MAIN OUTCOME MEASURE: The study measured the frequency of medical claims that document dietary counseling ≤90 days after hospitalization (ie, an episode of care) for CVD events (coronary artery bypass grafting, acute myocardial infarction, congestive heart failure, and percutaneous coronary intervention). Dietary counseling documentation was defined as having an encounter-level International Classification of Diseases 10th Revision code for dietary counseling or current procedural terminology code for medical nutrition therapy or cardiac rehabilitation. STATISTICAL ANALYSES PERFORMED: Multivariable logistic regression was used to measure variation in documentation across gender, age, comorbidities, hospital geography, CVD event, and insurer. RESULTS: There were 175,631 episodes of care (congesitve heart failure 47.1%, acute myocardial infarction 28.7%, percutaneous coronary intervention 17.0%, and coronary artery bypass grafting 7.3%) among 146,185 individuals. Most episodes occurred among men (55.8%) and those older than age 65 years (71.9%). Dietary counseling was documented for 22.8% of episodes and was more common as cardiac rehabilitation (18.6%) than other encounter types (5.1%). In multivariable analysis, there was lower odds for dietary counseling documentation among those older than age 65 years (odds ratio [OR] 0.77; P < .001), women (OR 0.83; P < .001), with chronic kidney disease (OR 0.74; P < .001), or diabetes (OR 0.95; P < .001), but greater odds for those with obesity (OR 1.28; P < .001) and nonmetropolitan hospitals (OR 1.31; P < .001). Compared with coronary artery bypass grafting, acute myocardial infarction (OR 0.29; P < .001), confestive heart failure (OR 0.12; P < .001), and percutaneous coronary intervention (OR 0.36; P < .001) episodes had lower odds to have dietary counseling coded. Compared with Traditional Medicare, Medicaid and Medicare Advantage health maintenance organization plans had lower odds, whereas Commercial or Medicare Advantage preferred provider organization and Commercial health maintenance organization plans had higher odds to have dietary counseling documented. Results were mostly similar when evaluated by race. CONCLUSIONS: Dietary counseling was infrequently documented after hospitalization for CVD episodes in medical claims in a Michigan-based multipayer claims database with large variation by reason for hospitalization and patient factors.

BACKGROUND: Patient-physician relationships in healthcare can influence healthcare provision, patient engagement, and health outcomes. Little is known about youth preferences on types and characteristics of their healthcare providers. The aim of this study was to assess youth perspectives on preferences for and interactions with their healthcare providers. METHODS: We posed 5 open-ended questions to 1,163 MyVoice participants, a nationwide text message cohort of United States youth aged 14-24, on April 10, 2020 related to youth preferences for healthcare providers. Content analysis was used to develop a codebook. Responses were independently coded by two reviewers with discrepancies discussed to reach consensus. Descriptive statistics were calculated for demographics and frequency of codes. RESULTS: 944 (81%) participants responded to at least one question. Respondents had a mean age of 18.9 years (SD: 2.8) and were a majority female (53.6%) and White (56.3%). Youth reported "kindness" or other personality traits (31%) and education (30%) as important in choosing their doctor. Patient-physician concordance was not important to many youths (44%) and among those who reported concordance as important (55%), having the same gender was the most noted (68%). Youth suggested respect, open conversation, and addressing issues directly to help alleviate uncomfortable situations, though some would simply switch providers. CONCLUSION: Personality and empathy are important provider characteristics valued by youth. Female respondents preferred gender concordant providers, particularly for sexual health-related issues, and non-white respondents were more likely to prefer racial concordance. Strengthening professional and interpersonal skills among youth-serving providers may improve healthcare engagement and satisfaction among youth.

INTRODUCTION: Irreversible electroporation (IRE) is a tissue ablation technology that kills cells with short electrical pulses that do not induce thermal damage, thereby preserving the extracellular matrix. Preclinical research suggests that IRE may be developed as a tool for regenerative surgery by clearing existing host cells within a solid organ and creating a supportive niche for new cell engraftment. We hypothesized that hepatocytes transplanted by injection into the portal circulation would preferentially engraft within liver parenchyma pretreated with IRE. METHODS: Transgene-positive ß-galactosidase-expressing hepatocytes were isolated from B6.129S7-Gt(ROSA)26Sor/J (ROSA26) mice and transplanted by intrasplenic injection into wild-type littermates that received liver IRE pretreatment or control sham treatment. Engraftment of donor hepatocytes in recipient livers was determined by X-gal staining. RESULTS: Significantly higher numbers of X-gal+ donor hepatocytes engrafted in the livers of IRE-treated mice as compared to sham-treated mice. X-gal+ hepatocytes persisted in IRE-treated recipients for at least 11 d post-transplant and formed clusters. Immunostaining demonstrated the presence of HNF4A/Ki67/ß-galactosidase triple-positive cells within IRE-ablation zones, indicating that transplanted hepatocytes preferentially engrafted in IRE-treated liver parenchyma and proliferated. CONCLUSIONS: IRE pretreatment of the liver increased engraftment of transplanted hepatocytes within the IRE-ablation zone. IRE treatment of the host liver may be developed clinically as a strategy to increase engraftment efficiency of primary hepatocytes and/or hepatocytes derived from stem cells in cell transplant therapies.

BACKGROUND: Research on the long-term effects of COVID-19 infection is ongoing, and the psychological and physical impacts of Long Covid on youth is poorly understood. To assess these impacts, we surveyed youth regarding their experiences with, and perspectives on, the long-term effects of COVID-19. METHODS: We conducted a nationwide text message survey of youth ages 14-24 years in the United States. The survey asked four open ended questions regarding their experiences and perceptions regarding the long-term effects of COVID-19. Qualitative data was analyzed independently by three investigators using thematic analysis. Prevalence of codes were summarized using descriptive statistics. RESULTS: Among 1150 participants, 991 responded to at least one survey question (response rate 86.1%). The vast majority of our sample had COVID-19 or knew someone who did (75%), and approximately one third (32%) of youth indicated that they knew someone who had experienced symptoms consistent with Long Covid. Many youth (50%) reported worry and concern about Long Covid even if they, or someone they knew, did not have Long Covid. Among youth who were not concerned about Long Covid, the most commonly reported reasons were having received the vaccine (29%) and not having a prior COVID-19 infection (24%). CONCLUSIONS: Our findings suggest that among younger populations, there is significant concern regarding the long-term effects of COVID-19. Vaccination campaigns and youth-centered public health communication about Long Covid may not only reduce COVID-19 transmission, but also alleviate worries and concerns about Long Covid among youth.

BACKGROUND: Despite decades of calls for increased diversity in the health research workforce, disparities exist for many populations, including Black, Indigenous, and People of Color individuals, those from low-income families, and first-generation college students. To increase representation of historically marginalized populations, there is a critical need to develop programs that strengthen their path toward health research careers. High school is a critically important time to catalyze interest and rebuild engagement among youth who may have previously felt excluded from science, technology, engineering, and mathematics (STEM) and health research careers. METHODS: The overall objective of the MYHealth program is to engage high school students in a community-based participatory research program focused on adolescent health. Investigators will work alongside community partners to recruit 9th through 12th graders who self-identify as a member of a group underrepresented in STEM or health research careers (e.g., based on race and ethnicity, socioeconomic status, first generation college student, disability, etc.). MYHealth students are trained to be co-researchers who work alongside academic researchers, which will help them to envision themselves as scientists capable of positively impacting their communities through research. Implemented in three phases, the MYHealth program aims to foster a continuing interest in health research careers by developing: 1) researcher identities, 2) scientific literacy, 3) scientific self-efficacy, and 4) teamwork and leadership self-efficacy. In each phase, students will build knowledge and skills in research, ethics, data collection, data analysis, and dissemination. Students will directly collaborate with and be mentored by a team that includes investigators, community advisors, scientific advisors, and youth peers. DISCUSSION: Each year, a new cohort of up to 70 high school students will be enrolled in MYHealth. We anticipate the MYHealth program will increase interest and persistence in STEM and health research among groups that have been historically excluded in health research careers.

This technical paper introduces a novel organ preservation system based on isochoric (constant volume) supercooling. The system is designed to enhance the stability of the metastable supercooling state, offering potential long-term preservation of large biological organs at subfreezing temperatures without the need for cryoprotectant additives. Detailed technical designs and usage protocols are provided for researchers interested in exploring this field. The paper also presents a control system based on the thermodynamics of isochoric freezing, utilizing pressure monitoring for process control. Sham experiments were performed using whole pig liver sourced from a local food supplier to evaluate the system's ability to sustain supercooling without ice nucleation for extended periods. The results demonstrated sustained supercooling without ice nucleation in pig liver tissue for 24 and 48 h. These findings suggest the potential of this technology for large-volume, cryoprotectant-free organ preservation with real-time control over the preservation process. The simplicity of the isochoric supercooling device and the design details provided in the paper are expected to serve as encouragement for other researchers in the field to pursue further research on isochoric supercooling. However, final evidence that these preserved organs can be successfully transplanted is still lacking.
RESUMO
BACKGROUND: Social gatherings are frequent sources of COVID-19 infections, especially among youth. However, little is known about youth testing behaviors before and after gatherings. Our aim was to assess behaviors and perceptions of youth related to testing for COVID-19 before or after social gatherings in order to inform efforts to reduce disease spread. METHODS: Five open-ended questions were texted to participants aged 14-24 throughout the United States via MyVoice. Using a content analysis approach, two investigators reviewed responses by question, developed a codebook, and independently applied codes. Discrepancies were resolved via discussion. Code frequency and demographic data were summarized using descriptive statistics. RESULTS: Of 1204 participants, 989 responded to at least one question (RR = 94.1%). The mean age was 20.2 years (SD: 2.4 years). Most participants (80.7%) reported testing for COVID-19 at least once. Most (70.6%) were likely to test following an event, especially "[i]f someone at the gathering tested positive," while a smaller number (50.9%) endorsed testing prior to a gathering. Of youth who would not get tested, being vaccinated was the highest reported. CONCLUSION: Youth in our nationwide sample are likely to test for COVID-19 after an event, though less likely if they are vaccinated. Their desire to test is primarily driven by symptoms, exposures, and requirements. Youth are interested in increased access to home testing. Youth-centered communications regarding testing recommendations and increased test availability for youth may reduce COVID-19 spread among young people and inform future pandemic recommendations.

This study was motivated by the increasing interest in finding ways to preserve organs in a supercooled state for transplantation. Previous research with small volumes suggests that the isochoric (constant volume) thermodynamic state enhances the stability of supercooled solutions. The primary objective of this study was to investigate the feasibility of storing a large organ, such as the pig liver, in a metastable isochoric supercooled state for clinically relevant durations. To achieve this, we designed a new isochoric technology that employs a system consisting of two domains separated by an interior boundary that can transfer heat and pressure, but not mass. The liver is preserved in one of these domains in a solution with an intracellular composition, which is in osmotic equilibrium with the liver. Pressure is used to monitor the thermodynamic state of the isochoric chamber. In this feasibility study, two pig livers were preserved in the device in an isochoric supercooled state at -2°C. The experiments were terminated voluntarily, one after 24 h and the other after 48 h of supercooling preservation. Pressure measurements indicated that the livers did not freeze during the isochoric supercooling preservation. This is the first proof that organs as large as the pig liver can remain supercooled for extended periods of time in an isotonic solution in an isochoric system, despite an increased probability of ice nucleation with larger volumes. To serve as controls and to test the ability of pressure monitoring to detect freezing in the isochoric chamber, an experiment was designed in which two pig livers were frozen at -2°C for 24 h and the pressure monitored. Histological examination with H&E stains revealed that the supercooled liver maintained a normal appearance, even after 48 h of supercooling, while tissues in livers frozen to -2°C were severely disrupted by freezing after 24 h.
RESUMO
SIGNIFICANCE: Uncorrected refractive error is the main cause of visual impairment in U.S. youth and has profound impacts on individuals and society. Identifying and addressing barriers to eyeglasses in this population are critical to maximize youth academic performance, workplace productivity, and quality of life. PURPOSE: We aimed to understand youth experiences with eye health, assess the value that youth place on vision, and identify barriers to refractive correction directly from a nationwide sample of youth to inform interventions to address uncorrected refractive error in this population. METHODS: An open-ended poll was distributed to the MyVoice Text Message Cohort of U.S. youth eliciting youth experiences with eye health and barriers to wearing eyeglasses. Text message responses were coded using grounded theory. RESULTS: Of 1204 recipients, 88.3% (n = 1063) responded. The mean age ± standard deviation was 20.3 ± 2.4 years, 58.8% (n = 625) were male, 74.0% (n = 787) were White, and 41.4% (n = 440) reported low socioeconomic status. Four major themes emerged from the open-ended responses: (1) many youth have experienced problems with their eyes or eyesight (n = 699 [65.8%]); (2) many youth value their eyesight highly (n = 905 [85.1%]; e.g., "Eyesight is one of the most important aspects of my health, particularly in our digital world "); (3) common reasons youth might not wear glasses even if they need them include concerns over appearance (n = 553 [52.0%]; e.g., "I thought every pair made me look ugly "), cost (n = 171 [16.1%]), inconvenience (n = 166 [15.6%]), and discomfort (n = 104 [9.8%]); and (4) youth are open to purchasing eyeglasses online (n = 539 [50.7%]). CONCLUSIONS: Appearance, cost, inconvenience, and discomfort are critical barriers to wearing eyeglasses among U.S. youth. A multisectoral response is necessary to address these barriers.

Importance: Rights and access for transgender individuals, including the participation of transgender athletes in sports, have long been debated. These discussions often center around fairness and mental health impacts on youths associated with identity-based inclusion in sports. Objective: To assess the experiences and perspectives of adolescents and young adults on the inclusion of transgender individuals in competitive sports. Design, Setting, and Participants: In this qualitative study, 5 open-ended survey questions were sent to the MyVoice cohort from December 10 to 17, 2021. MyVoice is a nationwide text-message polling platform of US youths aged 14 to 24 years. All coding and subsequent analysis was completed between January 10 and December 11, 2022. Main Outcomes and Measures: Qualitative perspectives of youths regarding transgender athlete participation in sports as measured by survey responses. Responses were reviewed using an inductive approach to qualitative thematic analysis to develop a codebook. The codes were independently applied to all responses by 2 investigators; discrepancies were resolved with discussion. Summary statistics were calculated for demographic characteristics and code frequencies, and χ2 tests (α = .05, 2-tailed) were used to evaluate differences in opinion based on gender identity and participation in competitive sports. Results: A total of 905 of 1199 youths (75%) responded to the survey. Respondents had a mean (SD) age of 20 (2) years; 482 (53%) identified as male, 29 (3%) identified as transgender, and 306 (34%) reported having participated in high school and/or collegiate athletics. Three themes emerged: (1) youths differed regarding the inclusion of transgender athletes based on gender identity vs sex assigned at birth, (2) many youths did not have personal experience related to the inclusion of transgender athletes, and (3) youths were uncertain about the impacts of gender identity-based participation on cisgender individuals but perceived positive impacts for transgender individuals. Nearly half of respondents (327 of 691 [47%]) thought that transgender athletes should participate based on their gender identity or personal preference, whereas 240 (35%) favored participation based on sex assigned at birth or in a transgender-only category. Respondents mentioned concern about the fairness of identity-based participation, specifically for cisgender women, but many (410 of 697 [59%]) also reported that it would be affirming for transgender athletes to participate based on gender identity. Conclusions and Relevance: The youths in our study differed in their opinions regarding sports participation of transgender youths, but many felt that inclusive policies would affirm and support the mental health of transgender individuals. Negative impacts on fairness were noted by some respondents. These findings suggest that nuanced policies are needed to address the participation of transgender athletes in competitive sports and should consider the impacts on and perspectives of youths most affected.

BACKGROUND: Pancreatic islet transplantation via infusion through the portal vein, has become an established clinical treatment for patients with type 1 diabetes. Because the engraftment efficiency is low, new approaches for pancreatic islets implantation are sought. The goal of this study is to explore the possibility that a non-thermal irreversible electroporation (NTIRE) decellularized matrix in the liver could be used as an engraftment site for pancreatic islets. MATERIALS AND METHODS: Pancreatic islets or saline controls were injected at sites pre-treated with NTIRE in the livers of 7 rats, 16 hours after NTIRE treatment. Seven days after the NTIRE treatment, islet graft function was assessed by detecting insulin and glucagon in the liver with immunohistochemistry. RESULTS: Pancreatic islets implanted into a NTIRE-treated volume of liver became incorporated into the liver parenchyma and produced insulin and glucagon in 2 of the 7 rat livers. Potential reasons for the failure to observe pancreatic islets in the remaining 5/7 rats may include local inflammatory reaction, graft rejection, low numbers of starting islets, timing of implantation. CONCLUSIONS: This study shows that pancreatic islets can become incorporated and function in an NTIRE-generated extracellular matrix niche, albeit the success rate is low. Advances in the field could be achieved by developing a better understanding of the mechanisms of failure and ways to combat these mechanisms.

BACKGROUND: Adolescence is a critical time for adopting health behaviors which continue through adulthood. There is a lack of data regarding perspectives of US adolescents and young adults on their dental health and oral hygiene practice. METHODS: Adolescents and young adults, age 14-24, from MyVoice, a nationwide text message poll of youth. were asked five open-ended questions on the importance of dental health and impact of the COVID-19 pandemic. Responses were qualitatively analyzed using thematic analysis. Chi-square test was used to examine differences in experiences by demographics. RESULTS: Of 1,148 participants, 932 responded to at least one question. The mean age was 19 years. Respondents were largely male (49.5%) and non-Hispanic white (62.4%). Most (92%) respondents perceived dental health as important or somewhat important and emphasized overall dental health and hygiene (38.6%) and aesthetics (18.3%). About half (49.2%) of respondents stated they have had at least one cavity since middle school. Just over half (54.8%) reported brushing and flossing to care for their dentition. 58% visited a dentist at least every 6 months, while 38% visited a dentist less frequently or not at all. Being non-cisgender, non-Hispanic black, Hispanic, and receipt of free or reduced lunch was associated with less frequent dental visits. 44% stated COVID-19 impacted their dental health, with many mentioning scheduling difficulties or worsened dental hygiene. CONCLUSIONS: Most youth in our study consider dental health important, though their oral hygiene practice may not follow ADA guidelines and self-reported dental caries are high. Dental healthcare among youth has been affected by the COVID-19 pandemic with interruption in regular dental visits and changes in hygiene habits.

Human induced pluripotent stem cell (iPSC)-derived liver organoids serve as models of organogenesis, disease, drug screening, and regenerative medicine. Prevailing methods for generating organoids rely on Matrigel, whose batch-to-batch variability and xenogeneic source pose challenges to mechanistic research and translation to human clinical therapy. In this report, we demonstrate that self-assembled Matrigel-free iPSC-derived organoids developed in rotating wall vessels (RWVs) exhibit greater hepatocyte-specific functions than organoids formed on Matrigel. We show that RWVs produce highly functional liver organoids in part by eliminating the need for Matrigel, which has adverse effects on hepatic lineage differentiation. RWV liver organoids sustain durable function over long-term culture and express a range of mature functional genes at levels comparable to adult human liver, while retaining some fetal features. Our results indicate that RWVs provide a simple and high-throughput way to generate Matrigel-free liver organoids suitable for research and clinical applications.

BACKGROUND: Gabapentinoids, including gabapentin and pregabalin, are commonly prescribed for neuropathic pain, but robust evidence recommends against using gabapentinoids for the treatment of carpal tunnel syndrome (CTS). We aimed to quantify national prescribing patterns of gabapentinoids for CTS. METHODS: We performed a retrospective population-based cohort study using claims data of gabapentinoid-naïve patients with a new diagnosis of CTS (2009-2016). Our primary outcome was a new gabapentinoid fill for CTS. We assessed temporal trends and characteristics associated with a gabapentinoid fill. Multivariable logistic regression was used to evaluate the association between patient-level factors and a new gabapentinoid fill for CTS. RESULTS: Of the 248 324 previously gabapentinoid-naïve patients with CTS, 9589 patients (4%) filled a gabapentinoid prescription. Sixty-one percent were prescribed by primary care providers or medical subspecialists. Patients with a history of neck pain (odds ratio [OR]: 1.31, 95% confidence interval [CI], 1.25-1.38), back pain (OR: 1.25, 95% CI, 1.20-1.31), arthritis (OR: 1.25, 95% CI, 1.18-1.31), and other pain conditions (OR: 1.26, 95% CI, 1.20-1.31) were associated with an increased odds of a new gabapentinoid fill. In addition, patients with a history of alcohol or substance use disorder were significantly associated with a new gabapentinoid prescription fill (OR: 1.33, 95% CI, 1.20-1.47). CONCLUSIONS: Despite evidence recommending against the use of gabapentinoids for CTS, gabapentinoids were frequently initiated among those with higher risk for misuse, including substance use disorders. Given the effectiveness of bracing or surgery for CTS and the risks associated with gabapentinoids, efforts aimed at disseminating evidence-based treatment for CTS are critical to minimize the harms of gabapentinoid misuse.

Cellular lattice structures possess high strength-to-weight ratios suitable for advanced lightweight engineering applications. However, their quality and mechanical performance can degrade because of defects introduced during manufacturing or in-service. Their complexity and small length scale features make defects difficult to detect using conventional nondestructive evaluation methods. Here we propose a current injection-based method, electrical resistance tomography (ERT), that can be used to detect damaged struts in conductive cellular lattice structures with their intrinsic electromechanical properties. The reconstructed conductivity distributions from ERT can reveal the severity and location of damaged struts without having to probe each strut. However, the low central sensitivity of ERT may result in image artifacts and inaccurate localization of damaged struts. To address this issue, this study introduces an absolute, high throughput, conductivity reconstruction algorithm for 3D ERT. The algorithm incorporates a strut-based normalized sensitivity map to compensate for lower interior sensitivity and suppresses reconstruction artifacts. Numerical simulations and experiments on fabricated representative cellular lattice structures were performed to verify the ability of ERT to quantitatively identify single and multiple damaged struts. The improved performance of this method compared with classical ERT was observed, based on greatly decreased imaging and reconstructed value errors.
