Genomic studies are now poised to explore whole communities of species. The ~70 species of woody plants that anchor the coastal ecosystems of the tropics, collectively referred to as mangroves, are particularly suited to this exploration. In this study, we de novo sequenced the whole genomes of 32 mangroves, which we combined with other sequences of 30 additional species, comprising almost all mangroves globally. These community-wide genomic data will be valuable for ecology, evolution and biodiversity research. While the data revealed 27 independent origins of mangroves, the total phylogeny shows only modest increases in species number, even in coastal areas of active speciation, suggesting that mangrove extinction is common. A possible explanation for common extinction is the frequent sea-level rises and falls (SLRs and SLFs) documented in the geological record. Indeed, near-extinctions of species with extremely small population size (N) often happened during periods of rapid SLR, as revealed by the genome-wide heterozygosity of almost all mangroves. Reduction in N has possibly been further compounded by population fragmentation and the subsequent accumulation of deleterious mutations, thus pushing mangroves even closer to extinction. Crucially, the impact of the next SLR will be exacerbated by human encroachment into these mangrove habitats, potentially altering the ecosystems of tropical coasts irreversibly.

Sex is emerging as an important clinical variable associated with surgical outcomes and decision making. However, its relevance in regard to baseline and treatment differences in primary and incisional ventral hernia repair remains unclear.This is a retrospective cohort study using the Abdominal Core Health Quality Collaborative database to identify elective umbilical, epigastric, or incisional hernia repairs. Propensity matching was performed to investigate confounder-adjusted treatment differences between men and women. Treatments of interest included surgical approach (minimally invasive or open), mesh use, mesh type, mesh position, anesthesia type, myofascial release, fascial closure, and fixation use.A total of 8,489 umbilical, 1,801 epigastric, and 16,626 incisional hernia repairs were identified. Women undergoing primary ventral hernia repair were younger (umbilical 46.4 vs 54 years, epigastric 48.7 vs 52.7 years), with lower BMI (umbilical 30.4 vs 31.5, epigastric 29.2 vs 31.1), and less likely diabetic (umbilical 9.9% vs 11.4%, epigastric 6.8% vs 8.8%). Women undergoing incisional hernia repair were also younger (mean 57.5 vs 59.1 years), but with higher BMI (33.1 vs 31.5), and more likely diabetic (21.4% vs 19.1%). Propensity-matched analysis included 3,644 umbilical, 1,232 epigastric, and 12,480 incisional hernias. Women with incisional hernia were less likely to undergo an open repair (60.2% vs 63.4%, p0.001) and have mesh used (93.8% vs 94.8%, p = 0.02). In umbilical and incisional hernia repairs, women had higher rates of intraperitoneal mesh placement and men had higher rates of preperitoneal and retro-muscular mesh placement.Small but statistically significant treatment differences in operative approach, mesh use, and mesh position exist between men and women undergoing ventral hernia repair. It remains unknown whether these treatment differences result in differing clinical outcomes.

Globally, collapse of ecosystems—potentially irreversible change to ecosystem structure, composition and function—imperils biodiversity, human health and well‐being. We examine the current state and recent trajectories of 19 ecosystems, spanning 58° of latitude across 7.7 M km2, from Australia's coral reefs to terrestrial Antarctica. Pressures from global climate change and regional human impacts, occurring as chronic ‘presses’ and/or acute ‘pulses’, drive ecosystem collapse. Ecosystem responses to 5–17 pressures were categorised as four collapse profiles—abrupt, smooth, stepped and fluctuating. The manifestation of widespread ecosystem collapse is a stark warning of the necessity to take action. We present a three‐step assessment and management framework (3As Pathway Awareness, Anticipation and Action) to aid strategic and effective mitigation to alleviate further degradation to help secure our future.

Primary care providers play a vital role for HIV prevention and care in high burden areas of the Southeast United States. Studies reveal that only a third of these providers had previous HIV-related training. We evaluated the effects of targeted online continuing medical education training on HIV-related knowledge, attitudes and practices among providers in the Southeast. During April 2017–February 2018, we administered baseline and six-month follow-up surveys to assess changes attributed to online training among a representative sample of providers from six Southeast locations. Data were analyzed using logistic regression analysis (p < 0.05). Baseline and follow-up surveys were completed by 349 participants (61.2% female, 64.6% white, 69.6% physicians, and 27.5% aged 40 years or less); 18% (n = 63) of whom visited online training websites sent following the baseline survey. Comparing baseline versus follow-up responses, providers who completed online training were half as likely to identify “patients’ age” (30% vs. 15%) and “patients’ race” (3% vs. 1.4%) as barriers to discussing sex with clients; survey responses by participants who declined training remained unchanged. Based on baseline versus follow-up responses, providers who visited online training websites were more likely to become familiar with preexposure prophylaxis (PrEP) (38% vs. 58%); participants who declined training remained unchanged at 45%. No impact on clinical practices such as PrEP prescriptions was identified. Targeted online training can enhance HIV readiness and should be explored for providers in the Southeast, particularly for enhancing PrEP service delivery.

Mental health (MH) disorders are associated with HIV-related risk and health outcomes. Primary care providers (PCPs) conducting MH screenings can link persons living with HIV (PWH) to appropriate services, particularly in HIV burden areas of Southeastern States (the South). Little data exist on PCPs’ MH screening practices. Depression, MH history, and substance use screenings among PCPs were examined in the South. Rao-Scott chi-square (χ(2)[df]) statistics (p ≤ 0.05) analyzed MH screening between PCPs with and without PWH patients. Compared with PCPs without PWH patients, PCPs with PWH patients routinely screened for substance use more frequently (50.6% vs. 43.2%; χ(2)[1] = 20.3; p G 0.0001). Compared with PCPs without PWH patients, PCPs with PWH patients routinely screened for depression less frequently (36.2% vs.50.9%; χ(2)[1] = 32.0; p G 0.0001). Providers increasing MH screenings will improve HIV-related outcomes in the South.

To date, promising therapy for triple negative breast cancer (TNBC) remains a serious concern clinically because of poor prognosis, resistance, and recurrence. Herein, anti-cancer potential of synthetic cannabidiol (CBD; Purisys, GA; GMP grade) was explored either alone or as a chemosensitizer followed by post-treatment with doxorubicin (DOX) in TNBC (i.e., MDA-MB-231 and MDA-MB-468) cells. In comparison to 2D cultures, CBD showed greater IC(50) values in 3D (LDP2 hydrogel based) cultures of MDA-MB-231 (6.26-fold higher) and MDA-MB-468 (10.22-fold higher) cells. Next-generation RNA sequencing revealed GADD45A, GADD45G, FASN, LOX, and integrin (i.e., -α5, -β5) genes to be novelly altered by CBD in MDA-MB-231 cells. CIM-16 plate-based migration assay and western blotting disclosed that CBD induces anti-migratory effects in TNBC cells by decreasing fibronectin, vimentin, and integrins-α5, -β5, and -β1. Western blotting, RT-qPCR, and immunocytochemistry revealed that CBD inhibited autophagy (decreased Beclin1, and ATG-5, −7, and −16) of TNBC cells. CBD pre-treatment increased DOX sensitivity in TNBC cells. CBD pre-treatment accompanied by DOX treatment decreased LOX and integrin-α5, and increased caspase 9 protein respectively in MDA-MB-468 cells.

ImportanceBariatric surgery is the most effective treatment for severe obesity; yet it is unclear whether the long-term safety and comparative effectiveness of these operations differ across racial and ethnic groups.ObjectiveTo compare outcomes of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) across racial and ethnic groups in the National Patient-Centered Clinical Research Network (PCORnet) Bariatric Study.Design, Setting, and ParticipantsThis was a retrospective, observational, comparative effectiveness cohort study that comprised 25 health care systems in the PCORnet Bariatric Study. Patients were adults and adolescents aged 12 to 79 years who underwent a primary (first nonrevisional) RYGB or SG operation between January 1, 2005, and September 30, 2015, at participating health systems. Patient race and ethnicity included Black, Hispanic, White, other, and unrecorded. Data were analyzed from July 1, 2021, to January 17, 2022.ExposureRYGB or SG.OutcomesPercentage total weight loss (%TWL); type 2 diabetes remission, relapse, and change in hemoglobin A1c (HbA1c) level; and postsurgical safety and utilization outcomes (operations, interventions, revisions/conversions, endoscopy, hospitalizations, mortality, 30-day major adverse events) at 1, 3, and 5 years after surgery.ResultsA total of 36 871 patients (mean [SE] age, 45.0 [11.7] years; 29 746 female patients [81%]) were included in the weight analysis. Patients identified with the following race and ethnic categories: 6891 Black (19%), 8756 Hispanic (24%), 19 645 White (53%), 826 other (2%), and 783 unrecorded (2%). Weight loss and mean reductions in HbA1c level were larger for RYGB than SG in all years for Black, Hispanic, and White patients (difference in 5-year weight loss: Black, −7.6%; 95% CI, −8.0 to −7.1; P < .001; Hispanic, −6.2%; 95% CI, −6.6 to −5.9; P < .001; White, −5.9%; 95% CI, −6.3 to −5.7; P < .001; difference in change in year 5 HbA1c level: Black, −0.29; 95% CI, −0.51 to −0.08; P = .009; Hispanic, −0.45; 95% CI, −0.61 to −0.29; P < .001; and White, −0.25; 95% CI, −0.40 to −0.11; P = .001.) The magnitude of these differences was small among racial and ethnic groups (1%-3% of %TWL). Black and Hispanic patients had higher risk of hospitalization when they had RYGB compared with SG (hazard ratio [HR], 1.45; 95% CI, 1.17-1.79; P = .001 and 1.48; 95% CI, 1.22-1.79; P < .001, respectively). Hispanic patients had greater risk of all-cause mortality (HR, 2.41; 95% CI, 1.24-4.70; P = .01) and higher odds of a 30-day major adverse event (odds ratio, 1.92; 95% CI, 1.38-2.68; P < .001) for RYGB compared with SG. There was no interaction between race and ethnicity and operation type for diabetes remission and relapse.Conclusions and RelevanceVariability of the comparative effectiveness of operations for %TWL and HbA1c level across race and ethnicity was clinically small; however, differences in safety and utilization outcomes were clinically and statistically significant for Black and Hispanic patients who had RYGB compared with SG. These findings can inform shared decision-making regarding bariatric operation choice for different racial and ethnic groups of patients.

To help inform the development of more accessible, acceptable, and effective ethics consultation (EC) training programs, we conducted an EC training needs assessment, exploring ethics practitioners' opinions on: the relative importance of various EC practitioner competencies; the potential market for EC training (that is, how many individuals would benefit and how much individuals and hospitals would be willing to pay); and the preferred content, format, and characteristics of EC training.As part of a multipart study, we surveyed "best informants" who self-identified as the person most actively involved in EC or healthcare ethics in a random sample of 600 U.S. general hospitals, stratified for bed size.The competency that was ranked most important for a lead or solo ethics consultant was knowledge of ethics, while common sense was ranked least important. The median estimated number of individuals at each hospital who would benefit from EC training was six at the basic level, three at the advanced level, and two for EC management training. In 19.1 percent of hospitals, respondents thought their hospital would not be willing to pay anything for EC training within the next two years. Respondents thought potential trainees would be likely to participate in EC training on multiple different topics. Opinions varied widely on preferred formats. Most respondents thought it very important to be able to interact with instructors and with other trainees, practice EC skills, receive a certificate for completing EC training, and complete EC training during work hours.These findings provide U.S. population data that may be useful to healthcare educators and bioethics leaders in their efforts to develop EC training programs and products that match trainees' preferences and needs.

Extracellular Vesicles (EVs) were isolated from human umbilical cord mesenchymal stem cells (hUCMSCs) and were further encapsulated with cannabidiol (CBD) through sonication method (CBD EVs). CBD EVs displayed an average particle size of 114.1 ± 1.02 nm, zeta potential of -30.26 ± 0.12 mV, entrapment efficiency of 92.3 ± 2.21% and stability for several months at 4 °C. CBD release from the EVs was observed as 50.74 ± 2.44% and 53.99 ± 1.4% at pH 6.8 and pH 7.4, respectively after 48 h. Our in-vitro studies demonstrated that CBD either alone or in EVs form significantly sensitized MDA-MB-231 cells to doxorubicin (DOX) (*P 0.05). Flow cytometry and migration studies revealed that CBD EVs either alone or in combination with DOX induced G1 phase cell cycle arrest and decreased migration of MDA-MB-231 cells, respectively. CBD EVs and DOX combination significantly reduced tumor burden (***P 0.001) in MDA-MB-231 xenograft tumor model. Western blotting and immunocytochemical analysis demonstrated that CBD EVs and DOX combination decreased the expression of proteins involved in inflammation, metastasis and increased the expression of proteins involved in apoptosis. CBD EVs and DOX combination will have profound clinical significance in not only decreasing the side effects but also increasing the therapeutic efficacy of DOX in TNBC.

Background As hospitals have grown more complex, the ethical concerns they confront have grown correspondingly complicated. Many hospitals have consequently developed health care ethics programs (HCEPs) that include far more than ethics consultation services alone. Yet systematic research on these programs is lacking. Methods Based on a national, cross-sectional survey of a stratified sample of 600 US hospitals, we report on the prevalence, scope, activities, staffing, workload, financial compensation, and greatest challenges facing HCEPs. Results Among 372 hospitals whose informants responded to an online survey, 97% of hospitals have HCEPs. Their scope includes clinical ethics functions in virtually all hospitals, but includes other functions in far fewer hospitals: ethical leadership (35.7%), regulatory compliance (29.0%), business ethics (26.2%), and research ethics (12.6%). HCEPs are responsible for providing ongoing ethics education to various target audiences including all staff (77.0%), nurses (59.9%), staff physicians (49.0%), hospital leadership (44.2%), medical residents (20.3%) and the community/general public (18.4%). HCEPs staff are most commonly involved in policy work through review of existing policies but are less often involved in development of new policies. HCEPs have an ethics representative in executive leadership in 80.5% of hospitals, have representation on other hospital committees in 40.7%, are actively engaged in community outreach in 22.6%, and lead large-scale ethics quality improvement initiatives in 17.7%. In general, major teaching hospitals and urban hospitals have the most highly integrated ethics programs with the broadest scope and greatest number of activities. Larger hospitals, academically affiliated hospitals, and urban hospitals have significantly more individuals performing HCEP work and significantly more individuals receiving financial compensation specifically for that work. Overall, the most common greatest challenge facing HCEPs is resource shortages, whereas underutilization is the most common greatest challenge for hospitals with fewer than 100 beds. Respondents’ strategies for managing challenges include staff training and additional funds. Conclusions While this study must be cautiously interpreted due to its limitations, the findings may be useful for understanding the characteristics of HCEPs in US hospitals and the factors associated with these characteristics. This information may contribute to exploring ways to strengthen HCEPs.

Background In 1993, the Family and Medical Leave Act (FMLA) mandated 12 weeks of unpaid, job-protected leave. The current impact of taking 12 weeks of leave during residency has not been evaluated. Methods We examined the 2018 Accreditation Council for Graduate Medical Education (n = 24) specialty leave policies to determine the impact of 6- and 12-week leave on residency training, board eligibility, and fellowship training. We compared our findings with a 2006 study. Results In 2018, five (21%) specialties had policy language regarding parental leave during residency, and four (16%) had language regarding medical leave. Median leave allowed was 4 weeks (IQR 4-6). Six specialties (25%) decreased the number of weeks allowed for leave from 2006 to 2018. In 2006, a 6-week leave would cause a 1-year delay in board eligibility in six specialties; in 2018, it would not cause delayed board eligibility in any specialty. In 2018, a 12-week (FMLA) leave would extend training by a median of 6 weeks (mean 4.1, range 0-8), would delay board eligibility by 6-12 months in three programs (mean 2.25, range 0-12), and would delay fellowship training by at least 1 year in 17 specialties (71%). The impact of a 12-week leave was similar between medical and surgical specialties. Conclusions While leave policies have improved since 2006, most specialties allow for 6 weeks of leave, less than half of what is mandated by the FMLA. Moreover, a 12-week, FMLA-mandated leave would cause significant delays in board certification and entry into fellowship for most residency programs.

The Southeast accounted for most HIV diagnoses (52%) in the United States in 2015. Primary care providers (PCPs) play a vital role in HIV prevention for at-risk persons and treatment of persons living with HIV. We studied HIV-related training, knowledge, and clinical practices among PCPs in the Southeast to address knowledge gaps to inform HIV prevention strategies. Between April and August 2017, we conducted an on-line survey of a representative sample of PCPs in six Southeast jurisdictions with high rates of HIV diagnoses (Atlanta; Baltimore; Baton Rouge; District of Columbia; Miami; New Orleans). We defined HIV-related training as self-reported completion of any certified HIV/STD course or continuing education in past 24 months (prior to survey completion). We assessed associations between training and HIV testing practices, familiarity with nonoccupational post-exposure prophylaxis (nPEP) and pre-exposure prophylaxis (PrEP), and ever prescribing nPEP or PrEP. There were 820 participants after fielding 4595 surveys (29.6% adjusted response rate). In weighted analyses, 36.3% reported HIV-related training. Using adjusted prevalence ratio (aPR) and confidence intervals (CI), we found that PCPs with HIV-related training (compared to those with no training) were more likely to be familiar with nPEP (aPR = 1.32, 95% CI 1.05, 1.67) and PrEP (aPR = 1.67, 95% CI 1.19, 2.38); and to have ever prescribed PrEP to patients (aPR = 1.75, 95% CI 1.10, 2.78). Increased HIV-related trainings among PCPs in high HIV prevalence Southeast jurisdictions may be warranted. Strengthening nPEP and PrEP familiarity among PCPs in Southeast may advance national HIV prevention goals.

Laparoscopic sleeve gastrectomy and laparoscopic adjustable gastric banding have been popular alternatives to laparoscopic Roux-en-Y gastric bypass due to their technical ease and lower complication rates. Comprehensive longitudinal data are necessary to guide selection of the appropriate bariatric procedures for individual patients. We used the Truven Heath Analytics MarketScan® database between 2000 and 2015 to identify patients undergoing bariatric surgery. Kaplan-Meier and Cox proportional hazard regression analyses were performed to compare complication rates between laparoscopic gastric bypass and laparoscopic sleeve gastrectomy, as well as between laparoscopic gastric bypass and laparoscopic adjustable gastric banding. 256,830 individuals met search criteria. By 2015, laparoscopic sleeve gastrectomy was the most commonly performed bariatric procedure followed by laparoscopic gastric bypass and then laparoscopic adjustable gastric banding. Overall, laparoscopic sleeve gastrectomy and laparoscopic adjustable gastric banding had fewer complications relative to laparoscopic gastric bypass with the exceptions of heartburn, gastritis, and portal vein thrombosis following sleeve gastrectomy and heartburn and dysphagia following adjustable gastric banding. Laparoscopic sleeve gastrectomy is now the most commonly performed bariatric procedure in the USA. It is reassuring that its overall postoperative complication rates are lower relative to laparoscopic gastric bypass.

A 1999-2000 national study of U.S. hospitals raised concerns about ethics consultation (EC) practices and catalyzed improvement efforts. To assess how practices have changed since 2000, we administered a 105-item survey to "best informants" in a stratified random sample of 600 U.S. general hospitals. This primary article details the methods for the entire study, then focuses on the 16 items from the prior study. Compared with 2000, the estimated number of case consultations performed annually rose by 94% to 68,000. The median number of consults per hospital was unchanged at 3, but more than doubled for hospitals with 400+ beds. The level of education of EC practitioners was unchanged, while the percentage of hospitals formally evaluating their ECS decreased from 28.0% to 19.1%. The gap between large, teaching hospitals and small, nonteaching hospitals widened since the prior study. We suggest targeting future improvement efforts to hospitals where needs are not being met by current approaches to EC.

Extracellular vesicles (EV) mediate intercellular communication events and alterations in normal vesicle content contribute to function and disease initiation or progression. The ability to package a variety of cargo and transmit molecular information between cells renders EVs important mediators of cell-to-cell crosstalk. Latent membrane protein 1 (LMP1) is a chief viral oncoprotein expressed in most Epstein-Barr virus (EBV)-associated cancers and is released from cells at high levels in EVs. LMP1 containing EVs have been demonstrated to promote cell growth, migration, differentiation, and regulate immune cell function. Despite these significant changes in recipient cells induced by LMP1 modified EVs, the mechanism how this viral oncogene modulates the recipient cells towards these phenotypes is not well understood. We hypothesize that LMP1 alters EV content and following uptake of the LMP1-modified EVs by the recipient cells results in the activation of cell signaling pathways and increased gene expression which modulates the biological properties of recipient cell towards a new phenotype. Our results show that LMP1 expression alters the EV protein and microRNA content packaged into EVs. The LMP1-modified EVs also enhance recipient cell adhesion, proliferation, migration, invasion concomitant with the activation of ERK, AKT, and NF-κB signaling pathways. The LMP1 containing EVs induced transcriptome reprogramming in the recipient cells by altering gene expression of different targets including cadherins, matrix metalloproteinases 9 (MMP9), MMP2 and integrin-α5 which contribute to extracellular matrix (ECM) remodeling. Altogether, our data demonstrate the mechanism in which LMP1-modified EVs reshape the tumor microenvironment by increasing gene expression of ECM interaction proteins., Author summary Extracellular vesicles (EV) facilitate cell-to-cell crosstalk due to their capability to sort and transfer various cargoes. Multiple studies have shown changes in EV content and cargo affect their functions and contribute to pathological conditions such as cancer. EVs represent a mechanism through which cancer cells modify their microenvironment to enhance growth and metastasis. This study showed that LMP1, an EBV major oncoprotein which is released in EVs alters the EV content and cargo leading enhanced cell attachment, proliferation, migration and invasion. LMP1 modified EVs mediate the transfer of signaling molecules to recipient cells where they induce NF-κB, AKT and MAPK/ERK signaling pathways leading to alteration in gene expression especially those involved in ECM interaction. LMP1 containing EVs modify the microenvironment by upregulating cadherins, fibronectin, integrin-α5, MMP9 and MMP2 to promote a tumor permissive niche leading tumorigenesis or metastasis.

Few studies have reported the long-term results of minimally invasive Heller myotomy (HM) for the treatment of achalasia. Herein, we detail our 17-year experience with HM for the treatment of achalasia from a tertiary referral center.All patients undergoing elective HM at our institution from 2000 to 2017 were identified within a prospective institutional database. These patients were sent mail and electronic surveys to capture their symptoms of dysphagia, chest pain, and regurgitation pre- and postoperatively and were asked to evaluate their postoperative gastrointestinal quality of life. Responses from adult patients who underwent minimally invasive Heller myotomy with partial posterior (i.e., Toupet) fundoplication (HM-TF) were analyzed.294 patients were eligible for study inclusion; 139 (47%) completed our survey. Median time from HM-TF to survey response was 5.6 years. A majority of patients reported improvement in their dysphagia (91%), chest pain (70%), and regurgitation (87%) symptoms. Patients who underwent HM-TF more than 5 years ago were most likely to report heartburn symptoms. One (1%) patient went on to require esophagectomy for ongoing dysphagia and one (1%) patient required revisional fundoplication for their heartburn symptoms.Minimally invasive Heller myotomy and posterior partial fundoplication is a durable treatment for achalasia over the long term. Additional prospective and multi-institutional studies are needed to validate our results.

LMP1 is a notable viral protein that contributes to the modification of EV content and tumor microenvironment remodeling. LMP1-modified EVs enhance tumor proliferation, migration, and invasion potential and promote radioresistance. Currently, the mechanisms surrounding LMP1 incorporation into the host EV pathways are not well understood. This study revealed that LMP1 utilizes Hrs, Syntenin-1, and specific components of the ESCRT-III complex for release from the cell, enhancement of EV production, and metastatic properties of cancer cells. These findings begin to unravel the mechanism of LMP1 EV trafficking and may provide new targets to control EBV-associated cancers., Extracellular vesicles (EVs) are important mediators of cell-to-cell communication that are involved in both normal processes and pathological conditions. Latent membrane protein 1 (LMP1) is a major viral oncogene that is expressed in most Epstein-Barr virus (EBV)-associated cancers and secreted in EVs. LMP1-modified EVs have the ability to influence recipient cell growth, migration, and differentiation and regulate immune cell function. Despite the significance of LMP1-modified EVs in EBV malignancies, very little is understood about how this protein hijacks the host EV pathway for secretion. Using the biotin identification (BioID) method, we identified LMP1-proximal interacting proteins that are known to play roles in EV formation and protein trafficking. Analysis of the identified LMP1-interacting proteins revealed an enrichment in the ESCRT pathway and associated proteins, including CD63, Syntenin-1, Alix, TSG101, Hrs, and charged multivesicular body proteins (CHMPs). LMP1 transcriptionally upregulated and increased the protein expression of EV biogenesis and secretion genes. Nanoparticle tracking and immunoblot analysis revealed reduced levels of LMP1 EV packaging and of vesicle production following the knockdown of Syntenin-1, Alix, Hrs, and TSG101, with altered endolysosomal trafficking observed when Syntenin-1 and Hrs expression was reduced. Knockdown of specific ESCRT-III subunits (CHMP4B, -5, and -6) impaired LMP1 packaging and secretion into EVs. Finally, we demonstrate that the efficient secretion of LMP1-modified EVs promotes cell attachment, proliferation, and migration and tumor growth. Together, these results begin to shed light on how LMP1 exploits host ESCRT machinery to direct the incorporation of the viral oncoprotein into the EV pathway for secretion to alter the tumor microenvironment.

Introduction Since December 2010, Florida's Bureau of Tobacco Free Florida has aired a statewide tobacco education campaign to encourage smoking cessation. The Tobacco Free Florida campaign consists of evidence-based advertisements primarily characterized by strong emotional content and graphic imagery designed to increase awareness of the health risks of tobacco use. We evaluated the effect of the media campaign on population-level quit attempts by using a statewide representative sample of Florida adults aged 18 or older. Methods We examined data from 5,418 Florida adult cigarette smokers and recent quitters aged 18 or older from the Florida Adult Tobacco Survey, an annual, cross-sectional survey conducted from 2011 through 2018. The primary outcome was incidence of quit attempts in the previous 12 months. We used multivariable logistic regression models to estimate the odds of making a quit attempt as a function of advertising levels across state media markets. Rates of quit attempts in Florida were also estimated. Results Approximately 66% of smokers in the study made at least 1 quit attempt. Exposure to the campaign was associated with increased odds of a quit attempt in the previous 12 months (odds ratio = 1.25; P = .02) among smokers and recent quitters. The Tobacco Free Florida campaign was associated with an estimated 332,604 additional smokers making quit attempts per year during the study period. Conclusion The Tobacco Free Florida campaign affected cessation-related behaviors in Florida over an 8-year period. Evidence-based state tobacco education campaigns can accelerate progress toward the goal of reducing adult smoking.

Acute biliary disease is a ubiquitous acute surgical complaint. General surgeons managing emergency surgical patients must be knowledgeable and capable of identifying and caring for common presentations. This article discusses the work-up, diagnosis, and management of the varying pathologies that make up biliary disease including cholelithiasis, cholecystitis, biliary dyskinesia, choledocholithiasis, cholangitis, gallstone pancreatitis, and gallstone ileus. Also addressed are more challenging and rare presentations including pregnancy and bariatric anatomy.

The vertical sleeve gastrectomy is a bariatric procedure that was originally described as the initial step in the biliopancreatic diversion. It demonstrated effectiveness in weight loss as a single procedure, and the laparoscopic vertical sleeve gastrectomy, as a stand-alone procedure, is now the most commonly performed bariatric surgery worldwide. Due to its relative technical ease and long-term data that have established its durability in treating obesity and its related comorbid conditions, the sleeve gastrectomy has grown in popularity among patients and surgeons. While there are variations in the technical aspects of performing a laparoscopic sleeve gastrectomy, key steps must be undertaken to produce safe and effective outcomes. This article reviews the indications for bariatric surgery, patient selection, surgical technique and tips, perioperative care and complications after sleeve gastrectomy.

This study documents perceptions of the relative harmfulness of marijuana and alcohol to a person's health among adults in Oregon just before the first legal sales of marijuana for recreational use. We surveyed 1941 adults in Oregon in September 2015. Respondents were recruited using an address-based sampling (ABS) frame (n = 1314) and social media advertising (n = 627). Respondents completed paper surveys (ABS-mail, n = 388) or online surveys (ABS-online, n = 926; social media, n = 627). We used descriptive statistics and logistic regression models to examine perceptions of the relative harmfulness of marijuana and alcohol by sample characteristics, including substance use. About half of adults in Oregon (52.5%) considered alcohol to be more harmful to a person's health than marijuana. A substantial proportion considered the substances equally harmful (40.0%). Few considered marijuana to be more harmful than alcohol (7.5%). In general, respondents who were younger, male, and not Republican were more likely than others to consider alcohol more harmful than marijuana. Respondents who were older, female, and Republican were more likely to consider marijuana and alcohol equally harmful. Most individuals who reported using both marijuana and alcohol (67.7%) and approximately half of those who used neither substance (48.2%) considered alcohol to be more harmful than marijuana. Perceptions about the relative harmfulness of marijuana and alcohol may have implications for public health. As state lawmakers develop policies to regulate marijuana, it may be helpful to consider the ways in which those policies may also affect use of alcohol and co-use of alcohol and marijuana.

The study measured the relative influence of the following 3 factors in consumers' choice of hospitals: (1) cost, (2) out-of-pocket cost, and (3) safety as measured by Leapfrog Hospital Safety Score letter grade.Two hospital-choice questions regarding a hypothetical medical procedure were administered to 2357 online respondents. In question 1, respondents were assigned a scenario in which hospital 1 grade (A through D), hospital 2 grade (B through F), and hospital 2 total cost (3 levels) were randomly varied across respondents. In all cases, hospital 2 had a lower safety grade than hospital 1, and hospital 1 cost was held constant. In question 2, scenarios varied out-of-pocket cost rather than total cost. Demographic characteristics, income level, health status, health literacy, and opinions about value were also measured.On average, 94% and 88% of the respondents chose the safer hospital in questions 1 and 2, respectively. In all but 1 of 30 possible scenarios, where hospital 2 cost the individual $1000 less and was rated a B whereas hospital 1 was rated an A, respondents chose the safer hospital. Higher incomes, higher health literacy, and being female were associated with a stronger preference for hospital 1 (safer). There was a small effect suggesting that approximately 4% of the respondents selected a higher-cost hospital despite lower safety, but it was outweighed by predominant selections of the safer hospital.When shown Hospital Safety Score and cost information, consumers chose safer hospitals in 97% of cost and safety scenarios.

Objectives: Evidence-based guidelines recommend that HIV care providers offer retention-in-care services, but data are needed to assess service provision. Methods: We surveyed a probability sample of 1234 HIV care providers to estimate the percentage of providers whose practices offered 5 recommended retention services and describe providers’ perceptions of barriers to care among patients. Results: An estimated 21% of providers’ practices offered all 5 retention services. Providers at smaller (400 patients), private, and non-Ryan White HIV/AIDS Program (RWHAP)-funded practices, and practices without on-site case management were significantly less likely to provide patient navigation services or do systematic monitoring of retention. Providers’ most commonly perceived barriers to care among patients were mental health (40%), substance abuse (36%), and transportation (34%) issues. Conclusion: Deficiencies in the provision of key retention services are substantial. New strategies may be needed to increase the delivery of recommended retention services, especially among private, non-RWHAP-funded, and smaller facilities.

This study examines the relationships between trial of new marijuana or hashish products and unexpected highs, and use of edible products and unexpected highs.We conducted an online survey of 634 adult, past-year marijuana users in Colorado. We used logistic regression models to examine the relationship between new product trial or edible use and unexpected highs.In the first year that recreational marijuana was legal in Colorado, 71.4% of respondents tried a new marijuana or hashish product, and 53.6% used an edible product. Trial of new products was associated with greater odds of experiencing an unexpected high after controlling for age, gender, education, mental health status, current marijuana or hashish use, and mean amount of marijuana or hashish consumed in the past month (OR=2.13, p0.001). Individuals who reported having used edibles had greater odds of experiencing an unexpected high, after controlling for the same set of variables (OR=1.56, p0.05).People who try new marijuana or hashish products, or use edible marijuana or hashish products, are at greater risk for an unexpected high. It is possible that some negative outcomes associated with marijuana use and unexpected highs may be averted through a better understanding of how to use product packaging to communicate with consumers.

INTRODUCTION HIV treatment guidelines recommend initiating antiretroviral therapy (ART) regardless of CD4 cell (CD4) count, barring contraindications or barriers to treatment. An estimated 6% of persons receiving HIV care in 2013 were not prescribed ART. We examined reasons for this gap in the care continuum. METHODS During 2013-2014, we surveyed a probability sample of HIV care providers, of whom 1234 returned surveys (64.0% adjusted response rate). We estimated percentages of providers who followed guidelines and their characteristics, and who deferred ART prescribing for any reason. RESULTS Barring contraindications, 71.2% of providers initiated ART regardless of CD4 count. Providers less likely to initiate had caseloads ≤20 vs. >200 patients [adjusted prevalence ratios (aPR) 0.69, 95% confidence interval (CI): 0.47 to 1.02, P = 0.03], practiced at non-Ryan White HIV/AIDS Program-funded facilities (aPR 0.85, 95% CI: 0.74 to 0.98, P = 0.02), or reported pharmaceutical assistance programs provided insufficient medication to meet patients' needs (aPR 0.79, 95% CI: 0.65 to 0.98, P = 0.02). In all, 17.0% never deferred prescribing ART, 69.6% deferred for 1%-10% of patients, and 13.3% deferred for >10%. Among providers who had deferred ART, 59.4% cited patient refusal as a reason in >50% of cases, 31.1% reported adherence concerns because of mental health disorders or substance abuse, and 21.4% reported adherence concerns because of social problems, eg, homelessness, as factors in >50% of cases when deferring ART. CONCLUSIONS An estimated 29% of HIV care providers had not adopted recommendations to initiate ART regardless of CD4 count, barring contraindications, or barriers to treatment. Low-volume providers and those at non-Ryan White HIV/AIDS Program-funded facilities were less likely to follow this guideline. Among all providers, leading reasons for deferring ART included patient refusal and adherence concerns.

HIV disproportionately affects persons in Southeast United States. Primary care providers (PCPs) are vital for HIV prevention. Data are limited about their prescribing of antiretrovirals (ARVs) for prevention, including non-occupational post-exposure prophylaxis (nPEP), pre-exposure prophylaxis (PrEP), and antiretroviral therapy (ART). We examined these practices to assess gaps. During April–August 2017, we conducted an online survey of PCPs in Atlanta, Baltimore, Baton Rouge, Miami, New Orleans, and Washington, DC to assess HIV-related knowledge, attitudes and practices. Adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) were used to estimate correlates of nPEP, PrEP and ART prescribing practices. Adjusting for MSA and specialty, the weighted sample (n = 820, 29.6% adjusted response rate) comprised 60.2% white and 59.4% females. PCPs reported ever prescribing nPEP (31.0%), PrEP (18.1%), and ART (27.2%). Prescribing nPEP was associated with nPEP familiarity (aPR = 2.63, 95% CI 1.59, 4.35) and prescribing PrEP (aPR = 3.57, 95% CI 2.78, 4.55). Prescribing PrEP was associated with PrEP familiarity (aPR = 4.35, 95% CI 2.63, 7.14), prescribing nPEP (aPR = 5.00, 95% CI 2.00, 12.50), and providing care for persons with HIV (aPR = 1.56, 95% CI 1.06, 2.27). Prescribing ART was associated with nPEP familiarity (aPR = 1.89, 95% CI 1.27, 2.78) and practicing in outpatient public practice versus hospital-based facilities (aPR = 2.14 95% CI 1.51, 3.04), and inversely associated with collaborations involving specialists (aPR = 0.60, 95% CI 0.42, 0.86). A minority of PCPs surveyed from the Southeast report ever prescribing ARVs for prevention. Future efforts should include enhancing HIV care coordination and developing strategies to increase use of biomedical tools.

A high-affinity anti-cocaine monoclonal antibody, designated h2E2, is entering phase 1 clinical trials for cocaine abuse therapy. To gain insight into the molecular details of its structure that are important for binding cocaine and cocaine metabolites, the Fab fragment was generated and crystallized with and without ligand. Structures of the unliganded Fab and the Fab fragment bound to benzoylecgonine were determined, and were compared with each other and with other crystallized anti-cocaine antibodies. The affinity of the h2E2 antibody for cocaine is 4 nM, while that of the cocaine metabolite benzoylecgonine is 20 nM. Both are higher than the reported affinity for cocaine of the two previously crystallized anti-cocaine antibodies. Consistent with cocaine fluorescent quenching binding studies for the h2E2 mAb, four aromatic residues in the CDR regions of the Fab (TyrL32, TyrL96, TrpL91 and TrpH33) were found to be involved in ligand binding. The aromatic side chains surround and trap the tropane moiety of the ligand in the complex structure, forming significant van der Waals interactions which may account for the higher affinity observed for the h2E2 antibody. A water molecule mediates hydrogen bonding between the antibody and the carbonyl group of the benzoyl ester. The affinity of binding to h2E2 of benzoylecgonine differs only by a factor of five compared with that of cocaine; therefore, it is suggested that h2E2 would bind cocaine in the same way as observed in the Fab–benzoylecgonine complex, with minor rearrangements of some hypervariable segments of the antibody.

Background: Our previous study demonstrated that lower level of education was associated with increased rates of postoperative hospital visits following bariatric surgery, potentially seco...

Cutaneous immune-related adverse events (irAEs) are a known consequence of immune checkpoint inhibitor (ICI) therapy and may exhibit a spectrum of morphologic features both clinically and histologically. Lichenoid dermatitis associated with ICI therapy (LD-ICI) is the most frequently encountered histopathologic type of irAE biopsied by dermatologists. There is frequent clinical and histologic overlap between irAEs and several reactive and neoplastic dermatologic disorders; thus, clinical information is essential. LD-ICI with histologic, immunohistochemical, and molecular features typical of mycosis fungoides (MF) are unique. Here, we report a patient who developed LD-ICI with MF-like morphologic features with monoclonal T-cell receptor gene rearrangement on consecutive biopsies during ICI therapy. The development of monoclonal LD-ICI is important for clinicians and pathologists to recognize in patients receiving ICI therapy.

ObjectiveTo assess the return on investment (ROI) of the Florida tobacco control programme, the Bureau of Tobacco Free Florida (BTFF), in terms of healthcare expenditure savings and mortality cost saved as a result of reduced mortality due to the programme from 1999 to 2015.MethodsWe use a synthetic control method to estimate the impact of the BTFF on smoking-attributable mortality, years of life lost (YLL), healthcare expenditures, and the economic value of premature mortality due to smoking in Florida from 1999 through 2015. We calculated an ROI for healthcare expenditures and for the value of life years saved.ResultsFrom 1999 to 2015, adult smoking prevalence in Florida averaged 0.98 percentage points lower than prevalence in the synthetic control states (19.6% vs 20.6%). The ROI over the period from 1999 to 2015 was 9.61 for healthcare expenditures and 112.44 for premature mortality. These ROIs suggest that for every US$1 of expenditure by BTFF, smoking-attributable healthcare expenditures decreased by almost US$11 and reductions in the economic costs associated with YLL due to smoking-attributable mortality totaled approximately US$113.ConclusionsOur results suggest the BTFF resulted in fewer YLL, substantial healthcare cost savings and substantial savings in terms of mortality costs. The positive ROIs for healthcare expenditures and premature mortality suggest that the BTFF is a good investment of public funds.

Climate change with human direct pressures represent significant threats to the resilience of shoreline habitats like mangroves. A rapid, whole-of-system assessment strategy is needed to evaluate such threats, better linking innovative remote sensing with essential on-ground evaluations. Using the Shoreline Video Assessment Method, we surveyed around 190 km of the mostly mangrove-fringed (78%) coastline of Kien Giang Province, Vietnam. The aim was to identify anthropogenic drivers of degradation, establishing baseline for specific rehabilitation and protection strategies. Fish traps occupy at least 87% of shoreline mangroves, around which there were abundant human activities – like fishing, crabbing, farming, plus collecting firewood and foliage. Such livelihoods were associated with remnant, fringing mangrove that were largely degraded and threatened by erosion retreat, herbivory, and excessive cutting. Our assessment quantified associated threats to shoreline stability, along with previous rehabilitation intervention measures. The method offers key opportunities for effective conservation and management of vulnerable shoreline habitats.

Objectives: Evidence-based guidelines have long recommended that HIV care providers deliver HIV transmission risk-reduction (RR) services, but recent data are needed to assess their adoption. Methods: The authors surveyed a probability sample of 1234 US HIV care providers on delivery of 9 sexual behavior– and 7 substance use–related HIV transmission RR services and created an indicator of “adequate” delivery of services in each area, defined as performing approximately 70% or more of applicable services. Results: Providers were most likely to encourage patients to disclose HIV status to all partners since HIV diagnosis (81%) and least likely to ask about disclosure to new sex and drug injection partners at follow-up visits (both 41%). Adequate delivery of sexual behavior– and substance use–related RR services was low (37% and 43%, respectively). Conclusion: The majority of US HIV care providers may need additional support to improve delivery of comprehensive HIV transmission RR services.

This study examines the relationship between self-reports of being high on marijuana and perceptions about driving high or drunk. Data were collected in 2014 from an online convenience sample of adult, past 30-day marijuana and hashish users in Colorado and Washington (n = 865). Respondents were asked, "Were you high or feeling the effects of marijuana or hashish when you took this survey?" Logistic regression was used to assess the relationship between being high and beliefs about driving high, controlling for demographics and marijuana use. Respondents who reported being high at the time of survey administration had higher odds of agreeing with the statements, "I can safely drive under the influence of marijuana" (OR = 3.13, P < 0.001) and "I can safely drive under the influence of alcohol" (OR = 3.71, P < 0.001) compared with respondents who did not report being high. Respondents who were high also had higher odds of being open to driving high under certain circumstances. Being high may influence perceptions about the safety of drugged and drunk driving. The effectiveness of public health messages to prevent drugged and drunk driving may depend in part on how persuasive they are among individuals who are high.

INTRODUCTION Studies suggest that exposure to televised electronic cigarette (e-cigarette) advertising contributes to the recent increase in e-cigarette use among youth. This study examines the relationship between perceptions of e-cigarette advertisements and attitudes toward and intentions to use e-cigarettes among youth who had never used e-cigarettes. METHODS In May 2014, we conducted an online survey of 5020 youth aged 13 to 17. Participants were randomly assigned to answer questions about their attitudes toward and intentions to use e-cigarettes before or after viewing e-cigarette advertisements. Perceived effectiveness (PE) of advertisements was measured after ad exposure. Ordinary least squares models were used to assess the relationship between PE and study outcomes. RESULTS Among never e-cigarette users, greater PE was associated with more positive attitudes toward e-cigarettes (b = 0.74, P < .001) and intentions to use e-cigarettes (b = 0.16, P < .001). Findings suggest that PE is predictive of outcomes controlling for study condition, youth demographics, and media use variables. CONCLUSIONS After ad exposure, youth who have never used e-cigarettes previously perceive e-cigarettes as cooler, more fun, healthier, and more enjoyable. Youth who thought the ads were more effective were more likely to have a positive attitude toward e-cigarettes and greater intention to try e-cigarettes in the future. Restricting televised e-cigarette advertising may reduce e-cigarette initiation among youth. IMPLICATIONS Previous studies demonstrate that, among adults, PE is antecedent to actual ad effectiveness across a range of behaviors. To our knowledge, this is the first study to document the relationship between PE and advertising effectiveness among youth. It provides evidence that PE may be a useful tool to quantify the potential influence of advertising on youth-advertising that, in this case, is designed to market a consumer good that may be harmful to youth but that may also be used to develop public health campaigns.

Importance Bariatric surgery can lead to substantial improvements in type 2 diabetes (T2DM), but outcomes vary across procedures and populations. It is unclear which bariatric procedure has the most benefits for patients with T2DM. Objective To evaluate associations of bariatric surgery with T2DM outcomes. Design, Setting, and Participants This cohort study was conducted in 34 US health system sites in the National Patient-Centered Clinical Research Network Bariatric Study. Adult patients with T2DM who had bariatric surgery between January 1, 2005, and September 30, 2015, were included. Data analysis was conducted from April 2017 to August 2019. Interventions Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Main Outcome and Measures Type 2 diabetes remission, T2DM relapse, percentage of total weight lost, and change in glycosylated hemoglobin (hemoglobin A1c). Results A total of 9710 patients were included (median [interquartile range] follow-up time, 2.7 [2.9] years; 7051 female patients [72.6%]; mean [SD] age, 49.8 [10.5] years; mean [SD] BMI, 49.0 [8.4]; 6040 white patients [72.2%]). Weight loss was significantly greater with RYGB than SG at 1 year (mean difference, 6.3 [95% CI, 5.8-6.7] percentage points) and 5 years (mean difference, 8.1 [95% CI, 6.6-9.6] percentage points). The T2DM remission rate was approximately 10% higher in patients who had RYGB (hazard ratio, 1.10 [95% CI, 1.04-1.16]) than those who had SG. Estimated adjusted cumulative T2DM remission rates for patients who had RYGB and SG were 59.2% (95% CI, 57.7%-60.7%) and 55.9% (95% CI, 53.9%-57.9%), respectively, at 1 year and 86.1% (95% CI, 84.7%-87.3%) and 83.5% (95% CI, 81.6%-85.1%) at 5 years postsurgery. Among 6141 patients who experienced T2DM remission, the subsequent T2DM relapse rate was lower for those who had RYGB than those who had SG (hazard ratio, 0.75 [95% CI, 0.67-0.84]). Estimated relapse rates for those who had RYGB and SG were 8.4% (95% CI, 7.4%-9.3%) and 11.0% (95% CI, 9.6%-12.4%) at 1 year and 33.1% (95% CI, 29.6%-36.5%) and 41.6% (95% CI, 36.8%-46.1%) at 5 years after surgery. At 5 years, compared with baseline, hemoglobin A1cwas reduced 0.45 (95% CI, 0.27-0.63) percentage points more for patients who had RYGB vs patients who had SG. Conclusions and Relevance In this large multicenter study, patients who had RYGB had greater weight loss, a slightly higher T2DM remission rate, less T2DM relapse, and better long-term glycemic control compared with those who had SG. These findings can help inform patient-centered surgical decision-making.

In 2016, the U.S. Congress mandated that federal intelligence interrogators adhere to the methods of the U.S. Army Field Manual FM 2-22.3 (AFM) and that the manual be revised based upon empirically based evaluations of the interrogation methods' effectiveness with interviewees motivated to withhold information. In the present study, 120 participants took part in a testing situation in which half were induced to cheat. All participants were then accused of cheating and interrogated with either (a) a combination of AFM interrogation approaches that focused on the potential benefits of cooperation with the interviewer (cooperation-focused condition), or (b) a combination of AFM approaches that focused on the potential risks of withholding information (withholding-focused condition). Participants who cheated on the test were significantly more likely to admit their wrongdoing and to provide additional relevant information when interrogated with the withholding-focused approaches than when questioned with the cooperation-focused approaches. The "we know all" AFM approach was especially effective for eliciting truthful admission-related details. Participants reported high rapport with the interrogator in both the cooperation-focused and withholding-focused conditions. These findings indicate that the we-know-all approach can be effective for maintaining rapport and eliciting accurate information in brief interrogations.

This study provides estimates of the long-term cumulative impact of the Centers for Disease Control and Prevention's national tobacco education campaign, Tips From Former Smokers (Tips), on population-level smoking cessation. We used recently published estimates of the association between increased Tips campaign media doses and quit attempts to calculate campaign-attributable population sustained (6-month) quits during 2012-2015. Tips led to approximately 522,000 sustained quits during 2012-2015. These findings indicate that the Tips campaign's comprehensive approach to combining evidence-based messages with the promotion of cessation resources was successful in achieving substantial long-term cigarette cessation at the population level over multiple years.

E-cigarettes and other non-cigarette tobacco products are increasingly popular among youth. Little is known to inform public health efforts to reduce youth use. We examined psychosocial correlates of single and multiple tobacco product use among youth e-cigarette users. Data were from the 2014 Florida Youth Tobacco Survey (N = 69,923), a representative sample of Florida middle and high school students. Associations between combinations of e-cigarette, cigarette and other tobacco product (OTP) use and psychosocial variables were examined using multinomial logistic regression with an analytic sample of N = 2756. Most e-cigarette-using youth used at least one other product (81%). Perceiving cigarettes as easy to quit was significantly associated with greater likelihood of combined e-cigarette/OTP use (relative risk ratio (RRR) = 2.51, p < 0.001) and combined e-cigarette/cigarette/OTP use (RRR = 3.20, p < 0.0001). Thinking you will be smoking cigarettes in 5 years was associated with product combinations that include cigarettes. Tobacco company marketing receptivity was associated with multiple product user types. Given that specific psychosocial factors put youth at risk for concurrent use of e-cigarettes with tobacco products, public health efforts should address polytobacco use specifically, instead of individual product use. Youth perceptions about the ease of quitting cigarettes, intentions to continue smoking cigarettes and receptivity to tobacco company marketing are promising areas for messaging aimed at reducing e-cigarette polytobacco product use.

Hospital readmissions following bariatric surgery are high and it is necessary to identify modifiable risk factors to minimize this postoperative cost. We hypothesize that lower levels of education and health literacy are associated with increased risks of nonadherence, thus leading to increased emergency department (ED) visits and preventable readmissions postoperatively.Bariatric surgery patients presenting between October 2015 and December 2016 were administered a preoperative questionnaire that measured education level and the Rapid Estimate of Adult Literacy in Medicine-Short Form (REALM-SF) health literacy test. The rates of postoperative ED visits and readmissions were across education levels (≤12th grade versus12th grade) and health literacy scores (≤8th grade versus high school level). A composite "hospital visit" outcome was also assessed.Ninety-five patients were enrolled; 23 had ≤12th grade level education and 7 scored ≤8th grade on the REALM-SF. Patients with ≤12th grade education were significantly more likely to have a hospital visit after surgery, compared with patients with12th grade education (incidence rate ratio [IRR] 3.06, P = .008). No significant difference in ED visits, readmission, or hospital visits was seen when stratified by REALM-SF health literacy score.Lower level of education was associated with more than threefold increased risk of postoperative ED visits and readmission in our center's bariatric surgery patients. A patient's education level is a low-cost means to identify patients who are at risk for postoperative hospital visits, and who may benefit from enhanced educational efforts or more intensive postoperative follow-up.

Adolescents' use of electronic cigarettes (e-cigarettes) and exposure to e-cigarette TV advertising have increased in recent years, despite questions about their safety. The current study tests whether exposure to e-cigarette TV advertisements influences intentions to use e-cigarettes in the future and related attitudes.A parallel-group randomized controlled experiment was conducted and analyzed in 2014 using an online survey with a convenience sample of 3,655 U.S. adolescents aged 13-17 years who had never tried e-cigarettes. Adolescents in the treatment group viewed four e-cigarette TV advertisements.Adolescents in the treatment group reported a greater likelihood of future e-cigarette use compared with the control group. ORs for the treatment group were 1.54 (p=0.001) for trying an e-cigarette soon; 1.43 (p=0.003) for trying an e-cigarette within the next year; and 1.29 (p=0.02) for trying an e-cigarette if a best friend offered one. Adolescents in the treatment group had higher odds of agreeing that e-cigarettes can be used in places where cigarettes are not allowed (OR=1.71, p0.001); can be used without affecting those around you (OR=1.83, p0.001); are a safer alternative to cigarettes (OR=1.19, p=0.01); and are less toxic (OR=1.16, p=0.03).Exposure to e-cigarette advertising had relatively large and consistent effects across experimental outcomes. Together with the simultaneous increase in e-cigarette advertising exposure and e-cigarette use among adolescents, findings suggest that e-cigarette advertising is persuading adolescents to try this novel product. This raises concerns that continued unregulated e-cigarette advertising will contribute to potential individual- and population-level harm.

OBJECTIVE The objective of this study was to compare the relative effectiveness of two modes of delivering Behavioral Family Systems Therapy for Diabetes (BFST-D) to improve adherence and glycemic control among adolescents with type 1 diabetes with suboptimal glycemic control (HbA1c ≥9.0% [≥74.9 mmol/mol]): face to face in clinic (Clinic) and Internet videoconferencing (Skype) conditions. RESEARCH DESIGN AND METHODS Adolescents aged 12 to 18 years and at least one adult caregiver were randomized to receive BFST-D via the Clinic or Skype condition. Participants completed up to 10 therapy sessions within a 12-week period. Changes in youth- and parent-reported adherence and glycemic control were compared before and after the intervention and at follow-up assessment. RESULTS Using an intent-to-treat analytic approach, no significant between-group differences were identified between the before, after, and follow-up assessments. Groups were collapsed to examine the overall effects of BFST-D on adherence and glycemic control. Results identified that statistically significant improvements in adherence and glycemic control occurred from before to after the intervention; improvements were maintained at 3-month follow-up. CONCLUSIONS Delivery of BFST-D via Internet-based videoconferencing is viable for addressing nonadherence and suboptimal glycemic control in adolescents with type 1 diabetes, potentially reducing important barriers to care for youth and families.

In 2012, the Centers for Disease Control and Prevention launched a national tobacco education campaign, Tips From Former Smokers, that consisted of graphic, emotionally evocative, testimonial-style advertisements. This longitudinal study examines changes in beliefs, tobacco-related cognitions and intentions to quit smoking among U.S. adult smokers after a 12-week airing of the campaign (n = 4040 adult smokers pre- and post-campaign). Exposure to the campaign was associated with greater odds of intending to quit within the next 30 days [odds ratio (OR) = 1.28, P < 0.01] and within the next 6 months (OR = 1.12, P < 0.05), and quit intentions were stronger among respondents with greater campaign exposure (OR = 1.12, P < 0.01). Campaign exposure was also associated with significant changes in beliefs about smoking-related risks (ORs = 1.15-2.40) and increased worries about health (b = 0.30, P < 0.001). Based on study change rates applied to U.S. census data, an estimated 566 000 additional U.S. smokers reported their intention to quit smoking within the next 6 months as a result of viewing campaign advertisements. Campaign effects were consistent with the theory of reasoned action and an expanding body of research demonstrating that graphic, emotional advertisements are highly effective for prompting positive cessation-related cognitions and behavioral intentions.

Background:Little is known about clinicians’ adoption of recommendations of the International Association of Providers of AIDS Care and others for supporting adherence to antiretroviral therapy (ART).Methods:We surveyed a probability sample of US HIV care providers to estimate the percentage offering 3 ART adherence support services to most or all patients and assessed the characteristics of providers offering all 3 services (comprehensive support) to most or all patients.Results:Almost all providers (95.5%) discussed ART adherence at every visit, 60.1% offered advice about tools to increase adherence, 53.5% referred nonadherent patients for supportive services, and 42.8% provided comprehensive support. Nurse practitioners were more likely to offer comprehensive support as were providers who practiced at Ryan White HIV/AIDS Program-funded facilities, provided primary care, or started caring for HIV-infected patients within 10 years.Conclusion:Less than half of HIV care providers offered comprehensive ART adherence support. Certain subgroups may benefit from interventions to increase delivery of adherence support.

Purpose: To assess the relationship between youth’s exposure to the Food and Drug Administration’s national tobacco public education campaign, The Real Cost, and changes in campaign-targeted beliefs. Design: Longitudinal design with baseline survey and 2 postcampaign follow-up surveys. Sample: Youth from 75 US media markets (N = 1680) who completed all 3 surveys and had experimented with or were susceptible to future cigarette smoking. Measures: Exposure was measured by self-reported frequency of ad exposure and media market–level target rating points. Agreement with 30 self-reported tobacco-related beliefs was assessed in 3 categories: (1) beliefs specifically targeted by campaign messages (campaign-targeted belief), (2) beliefs not targeted by the campaign (nontargeted beliefs), and (3) beliefs corresponding to other media campaigns on air concurrent with The Real Cost (ambiguous beliefs). Analysis: Descriptive analyses of aggregate changes in beliefs and logistic regressions to examine the association between campaign exposure and beliefs. Intervention: The Real Cost. Results: Agreement with campaign-targeted beliefs increased from baseline to first and second follow-ups, with a mean relative increase of 10.4% and 11.5%, respectively. Nontargeted beliefs did not change substantially. Both measures of campaign exposure were positively associated with increased odds of agreeing with 5 of 8 campaign-targeted beliefs. Exposure was not significantly associated with 12 of 14 nontargeted tobacco-related beliefs. Discussion: A sustained national tobacco public education campaign can change population-level perceptions of tobacco-related harms among youth.

Since 2012, the Centers for Disease Control and Prevention (CDC) has implemented Tips From Former Smokers ( Tips), the first federally funded tobacco education campaign in the United States. To date, there are no evaluations of its long-term impact.To assess the impact of varied doses of the Tips campaign from 2012 through 2015 on cessation-related behaviors and intentions among U.S. smokers.We used a national probability-based online survey of cigarette smokers ( n = 22,189) and recent quitters ( n = 776) to examine associations between doses of Tips advertising, measured by gross rating points (GRPs), and intentions to quit smoking in the next 30 days and quit attempts within the past 3 months. A curvilinear (i.e., square root) functional form of GRPs was used to capture patterns of diminishing effects at higher GRP levels.An increase of 1,000 quarterly Tips GRPs at the media market level was associated with increased odds of making a quit attempt in the past 3 months (adjusted odds ratio = 1.23, p.001) and increased odds of intending to quit in the next 30 days (adjusted odds ratio = 1.17, p = .030).Results suggest that CDC-recommended media buys of 800 to 1,000 GRPs per quarter are sufficient to generate statistically significant increases in the likelihood of quit attempts in the past quarter.The Tips campaign has had a substantial impact on cessation behaviors among U.S. adult smokers over time. These data support the continued use of graphic and/or emotional media campaigns that encourage smokers to quit to further reduce tobacco use in the United States.

Over the past two decades, there has been a flurry of government papers and policy reports worldwide calling for increased number and diversity of doctoral researchers and a broadening of the curriculum to meet the developing needs of respective national ‘knowledge-driven’ economies. This has been followed by position papers and best practice examples of employability skills development in boundary-crossing doctoral programmes, especially in response to these initiatives. However, there is a disassociation between this ample literature expounding the new doctorate with its broader remit, inclusivity and production of ‘industry-ready’ graduates and the comparatively sparse literature on the doctoral candidates’ experiences of their programmes and career readiness. Within this review, we briefly outline international government initiatives and examples of the responses by Life Science and Biomedical doctoral programmes to address these various challenges. Furthermore, we explore the recent literature on the lived experience of doctoral researchers by examining their perception of the recent changes to the research context to make recommendations for universities and supervisors on how to better support an ever more diverse doctoral population for a wide range of career opportunities. Examples of how doctoral researchers themselves can make the best of currently available opportunities are also provided., The maelstrom of change in the research and employability context impinging on the doctorate demands universities and research supervisors adapt process, procedures and ethos, and that students become increasingly proactive.

Type 1 diabetes requires intensive self-management to avoid acute and long-term health complications. In the past two decades, substantial advances in technology have enabled more effective and convenient self-management of type 1 diabetes. Although proximal technologies (eg, insulin pumps, continuous glucose monitors, closed-loop and artificial pancreas systems) have been the subject of frequent systematic and narrative reviews, distal technologies have received scant attention. Distal technologies refer to electronic systems designed to provide a service remotely and include heterogeneous systems such as telehealth, mobile health applications, game-based support, social platforms, and patient portals. In this Review, we summarise the empirical literature to provide current information about the effectiveness of available distal technologies to improve type 1 diabetes management. We also discuss privacy, ethics, and regulatory considerations, issues of global adoption, knowledge gaps in distal technology, and recommendations for future directions.

BACKGROUND AND OBJECTIVE: Currently, the US Food and Drug Administration does not regulate electronic cigarette (e-cigarette) marketing unless it is advertised as a smoking cessation aid. To date, the extent to which youth and young adults are exposed to e-cigarette television advertisements is unknown. The objective of this study was to analyze trends in youth and young adult exposure to e-cigarette television advertisements in the United States. METHODS: Nielsen data on television household audiences’ exposure to e-cigarette advertising across US markets were examined by calendar quarter, year, and sponsor. RESULTS: Youth exposure to television e-cigarette advertisements, measured by target rating points, increased 256% from 2011 to 2013. Young adult exposure increased 321% over the same period. More than 76% of all youth e-cigarette advertising exposure occurred on cable networks and was driven primarily by an advertising campaign for 1 e-cigarette brand. CONCLUSIONS: E-cigarette companies currently advertise their products to a broad audience that includes 24 million youth. The dramatic increase in youth and young adult television exposure between 2011 and 2013 was driven primarily by a large advertising campaign on national cable networks. In the absence of evidence-based public health messaging, the current e-cigarette television advertising may be promoting beliefs and behaviors that pose harm to the public health. If current trends in e-cigarette television advertising continue, awareness and use of e-cigarettes are likely to increase among youth and young adults.
