Sexual Violence and Substance Use Diagnosed in Emergency Department Discharges in Hawaii, 2005-2014.

BACKGROUND: Substance use (SU) and sexual violence (SV) present unique challenges when contextualizing their relationship due to underreporting of SU and SV. Both are significant public health concerns with a large magnitude and expense to the overall U.S. and to the state of Hawaii, which is identified as a high-intensity drug-trafficking area. Since substance users have a higher risk for sexual violence than the general public, this study aims to analyze the proportion and demographics of emergency department (ED) visit individuals reporting sexual violence with or without substance use disorder and examine how the number of ED visits of individuals diagnosed with SV and SU disorder compare to all individuals. METHODS: Data from the Healthcare Cost and Utilization Project was used to examine the relationship between SV and SU. The database contained 3.5 million observations for 24 Hawaii hospitals from 2005-2014. The data was summarized in descriptive statistics and Chi-square tests were run to assess statistical significance for variables of interest. RESULTS: A greater proportion of individuals reporting sexual violence also reported substance use disorders compared to the general population of individuals. While 8% of all ED visits were related to SU, 17% of ED visits involving SV were also related to SU, demonstrating a statistically significant association between SV and SU. CONCLUSIONS: There is a greater need to further understand the complexity of the relationship between substance use and sexual violence. Sexual violence and substance use disorders share a complex relationship; survivors of sexual abuse may develop a substance use disorder, and those who use drugs and alcohol may be at an increased risk for sexual violence. Results from this study demonstrate visits for individuals reporting sexual violence have a greater proportion of substance use disorder than visits for the general population.

Mitigation Planning and Policies Informed by COVID-19 Modeling: A Framework and Case Study of the State of Hawaii.

In the face of great uncertainty and a global crisis from COVID-19, mathematical and epidemiologic COVID-19 models proliferated during the pandemic. Yet, many models were not created with the explicit audience of policymakers, the intention of informing specific scenarios, or explicit communication of assumptions, limitations, and complexities. This study presents a case study of the roles, uses, and approaches to COVID-19 modeling and forecasting in one state jurisdiction in the United States. Based on an account of the historical real-world events through lived experiences, we first examine the specific modeling considerations used to inform policy decisions. Then, we review the real-world policy use cases and key decisions that were informed by modeling during the pandemic including the role of modeling in informing planning for hospital capacity, isolation and quarantine facilities, and broad public communication. Key lessons are examined through the real-world application of modeling, noting the importance of locally tailored models, the role of a scientific and technical advisory group, and the challenges of communicating technical considerations to a public audience.

Assessing Health Data Security Risks in Global Health Partnerships: Development of a Conceptual Framework.

BACKGROUND: Health care databases contain a wealth of information that can be used to develop programs and mature health care systems. There is concern that the sensitive nature of health data (eg, ethnicity, reproductive health, sexually transmitted infections, and lifestyle information) can have significant impact on individuals if misused, particularly among vulnerable and marginalized populations. As academic institutions, nongovernmental organizations, and international agencies begin to collaborate with low- and middle-income countries to develop and deploy health information technology (HIT), it is important to understand the technical and practical security implications of these initiatives. OBJECTIVE: Our aim is to develop a conceptual framework for risk stratification of global health data partnerships and HIT projects. In addition to identifying key conceptual domains, we map each domain to a variety of publicly available indices that could be used to inform a quantitative model. METHODS: We conducted an overview of the literature to identify relevant publications, position statements, white papers, and reports. The research team reviewed all sources and used the framework method and conceptual framework analysis to name and categorize key concepts, integrate them into domains, and synthesize them into an overarching conceptual framework. Once key domains were identified, public international data sources were searched for relevant structured indices to generate quantitative counterparts. RESULTS: We identified 5 key domains to inform our conceptual framework: State of HIT, Economics of Health Care, Demographics and Equity, Societal Freedom and Safety, and Partnership and Trust. Each of these domains was mapped to a number of structured indices. CONCLUSIONS: There is a complex relationship among the legal, economic, and social domains of health care, which affects the state of HIT in low- and middle-income countries and associated data security risks. The strength of partnership and trust among collaborating organizations is an important moderating factor. Additional work is needed to formalize the assessment of partnership and trust and to develop a quantitative model of the conceptual framework that can help support organizational decision-making.

The Mediating Role of Different Types of Parental Support in the Social Disparity of Hope in Young Adulthood.

Research has shown hope to be associated with a person's well-being, but how it is affected by family factors is unclear. This study investigates whether family socio-economic status (SES) affects young adults' hope, and to what extent and how different types of parental support mediate this social disparity. The data is collected from a sample of Hong Kong youth (N = 760; 54.6% girls) which participated in a 7-year longitudinal study during age 15-22. The results from multiple regression models indicate that family SES significantly predicts hope. However, cultural and academic communication and career encouragement from parents in early years, and current parental emotional support fully mediate the relationship between family SES and hope, with parental emotional support being the strongest mediator. Implications for hope theory, practices for nurturing hope and further research are discussed to suggest possible actions.

Cost-effectiveness Applications of Patient-reported Outcome Measures (PROMs) in Spine Surgery.

Because of the rising health care costs in the United States, there has been a focus on value-based care and improving the cost-effectiveness of surgical procedures. Patient-reported outcome measures (PROMs) can not only give physicians and health care providers immediate feedback on the well-being of the patients but also be used to assess health and determine outcomes for surgical research purposes. Recently, PROMs have become a prominent tool to assess the cost-effectiveness of spine surgery by calculating the improvement in quality-adjusted life years (QALY). The cost of a procedure per QALY gained is an essential metric to determine cost-effectiveness in universal health care systems. Common patient-reported outcome questionnaires to calculate QALY include the EuroQol-5 dimensions, the SF-36, and the SF-12. On the basis of the health-related quality of life outcomes, the cost-effectiveness of various spine surgeries can be determined, such as cervical fusions, lumbar fusions, microdiscectomies. As the United States attempts to reduce costs and emphasize value-based care, PROMs may serve a critical role in spine surgery moving forward. In addition, PROM-driven QALYs may be used to analyze novel spine surgical techniques for value-based improvements.

Evidence and Implications Behind a National Decline in Primary Care Visits.

Primary care is the foundation of the health care system and the basis for new payment and delivery reforms in the USA. Yet since 2008, primary care visit rates dropped by 6-25% across a range of populations in five sources of national survey and administrative data. We hypothesize three likely mechanisms behind the decline: decreases in patients' ability, need, or desire to seek primary care; changes in primary care practice such as greater use of teams and non-face-to-face care; and replacement of in-person primary care visits with alternatives such as specialist, retail clinic, and commercial telemedicine visits. These mechanisms require further investigation. In the meantime, the trend prompts us to optimize the primary care visit and embrace the growth of alternatives while preserving the fundamental benefits of primary care.

Integrating Social Needs Into Health Care: A Twenty-Year Case Study Of Adaptation And Diffusion.

The US health care system has recently begun to account for patients' unmet social needs in care delivery and payment reform. This article presents a twenty-year qualitative case study of five stages of diffusion-testing and learning, standardization, replication, shifting from doing to enabling, and catalyzing broad adoption-of a practical approach for integrating social needs into clinical care. This case study of Health Leads and its funders confirms the importance of focusing on a clear aim, investing in model testing and standardization to enable subsequent responsiveness to the market, and the willingness of innovators and their investors to cede control of a model to allow local adaption and accelerate broad adoption.

Physician perspectives on the management of viral hepatitis and hepatocellular carcinoma in Myanmar.

BACKGROUND: In Myanmar, over five million people are infected with hepatitis B virus (HBV) and hepatitis C virus (HCV). Hepatitis has been a recent focus with the development of a National Strategic Plan on Hepatitis and plans to subsidize HCV treatment. METHODS: During a two-day national liver disease symposium covering HCV, HBV, hepatocellular (HCC), and end-stage liver disease (ESLD), physician surveys were administered using the automated response system (ARS) to assess physician knowledge, perceptions of barriers to screening and treatment, and proposed solutions. Multivariate logistic regression was used to estimate odds ratio (OR) relating demography and practice factors with higher provider knowledge and improvement. RESULTS: One hundred two physicians attending from various specialty areas (31.0% specializing in gastroenterology/hepatology and/or infectious disease) were of mixed gender (46.8% male), were younger than or equal to 40 years old (51.1% 20 to 40 years), had less experience (61.6% with ≤10 years of medical practice), were from the metropolitan area of Yangon (72.1%), and saw <10 liver disease patients per week (74.3%). The majority of physicians were not comfortable with treating or managing patients with liver disease. The post-test scores demonstrated an improvement in liver disease knowledge (9.0% ± 27.0) compared to the baseline pre-test scores; no variables were associated with significant improvement in hepatitis knowledge. Physicians identified the cost of diagnostic blood tests and treatment as the most significant barrier to treatment. Top solutions proposed were universal screening policies (46%), removal of financial barriers for treatment (29%), patient education (14%) and provider education (11%). CONCLUSIONS: Physician knowledge improved after this symposium, and many other needs were revealed by the physician input on barriers to care and their solutions. These survey results are important in guiding the next steps to improve liver disease management and future medical education efforts in Myanmar.

Bolstering Skin Grafts With a Surgical Scrub Brush: A Cost-effective Solution.

Objective: The objective of this article is to review the methods currently used for the bolstering of skin grafts and compare their advantages and disadvantages with those of the dry, sterile surgical scrub brush. We report a series of cases performed at a single institution and compare the cost-effectiveness, application, and limitations of this method with other options for skin graft bolstering. Methods: A PubMed search using the parameters "(bolster) AND skin graft" was conducted, yielding 85 results. A total of 40 publications met the criteria for our literature review. The costs of the foam bolsters utilized as stents for skin grafts were obtained from the Central Supply and Resource Division of the University of Louisville Hospital for a cost analysis. The cost per square centimeter of each bolster material was calculated. Results: At $0.003/cm2, the 3M Reston foam is the most inexpensive of the 3 bolster materials analyzed. The dry, sterile surgical scrub brush has a similar cost at $0.006/cm2 but carries the advantage of sterility. The material cost of negative pressure wound therapy is $0.47/cm2, and the cost of the system as a whole makes it a much more expensive alternative. In 6 patients with defects of varying size and location, the scrub brush bolster showed a near 100% graft take and no complications. Conclusions: The dry, sterile surgical scrub brush presents a readily available and low-cost option for the stenting of small skin grafts and should be considered a viable method in the armamentarium of available skin graft bolsters.

Assessment of Natural Variability of Maize Lipid Transfer Protein Using a Validated Sandwich ELISA.

Lipid transfer protein (LTP) is the main causative agent for rare food allergic reactions to maize. This paper describes a new, validated ELISA that accurately measures maize LTP concentrations from 0.2 to 6.4 ng/mL. The levels of LTP ranged from 171 to 865 µg/g of grain, a 5.1-fold difference, across a set of 49 samples of maize B73 hybrids derived from the Nested Association Mapping (NAM) founder lines and a diverse collection of landrace accessions from North and South America. A second set of 107 unique samples from 18 commercial hybrids grown over two years across 10 U.S. states showed a comparable range of LTP level (212-751 µg/g of grain). Statistical analysis showed that genetic and environmental factors contributed 63 and 6%, respectively, to the variance in LTP levels. Therefore, the natural variation of maize LTP is up to 5-fold different across a diverse collection of varieties that have a history of safe cultivation and consumption.

Inhibition of interleukin-5 induced false positive anti-drug antibody responses against mepolizumab through the use of a competitive blocking antibody.

Mepolizumab, a humanized IgG1 monoclonal antibody that blocks native homodimeric interleukin-5 (IL-5) from binding to the IL-5 receptor, has recently been approved for treatment of severe eosinophilic asthma. Our initial immunogenicity assay method for phase I and II studies utilized a bridging electrochemiluminescence format with biotin and ruthenium-labelled mepolizumab linked by anti-drug antibodies (ADA). We discovered that IL-5 significantly increased in dosed subjects from a phase II study and that the increased IL-5 was in the form of a drug-bound complex. We demonstrated that the elevated drug-bound IL-5 produced false-positive response in the in vitro ADA assay, in which drug-bound IL-5 dissociated and then bridged mepolizumab conjugates to yield positive signal. To eliminate the IL-5 interference, we compared two strategies: a solid-phase immunodepletion of IL-5 and an in-solution IL-5 immunocompetition. We identified the best competitive antibody for each purpose. We found both methods demonstrated similar effectiveness in reducing the false positive signal in IL-5 spiked samples; however, the in-solution immunocompetition for IL-5 had fewer false positives in study samples. Additionally, the in-solution immunocompetition method was experimentally simpler to execute. We modified the ADA assay by adding a pre-treatment step with a mepolizumab competitive anti- IL-5 antibody. Using this new method, we retested clinical samples from two phase II studies (MEA112997 and MEA114092). The confirmed ADA positive incidence was reduced from 29% and 61% to 1% and 8% with the modified in-solution immune inhibition method. Target interference is a fairly common problem facing immunogenicity testing, and target-induced false positive cannot be distinguished from true ADA response by the commonly used drug competitive confirmation assay. The approach and method used here for resolving target interference in ADA detection will be useful for differentiating between a true ADA response and target induced false positive as well as similar challenges in other programs.

Need For Improved Skin Cancer Surveillance in Pediatric Cancer Survivors.

Survivors of pediatric cancer are at increased risk of developing secondary malignancies, with non-melanoma skin cancer being the most common. These patients are also at increased risk of melanoma. Currently, guidelines provided by the National Cancer Institute and Children's Oncology Group emphasize the importance of annual clinical examination for skin cancer screening; however, the literature reports that less than one-third of survivors of pediatric cancer have ever had a clinical skin exam by a physician. In this article, we review the risk factors for skin cancer in survivors of pediatric cancer as well as the current evidence and recommendations for their care. We suggest that dermatologists collectively establish guidelines for skin cancer surveillance in survivors of pediatric cancer.

Real-Life Treatment Paradigms Show Adalimumab Is Cost-Effective for the Management of Ulcerative Colitis.

Background. Adalimumab is effective for the maintenance of remission in patients with moderate-to-severe ulcerative colitis (UC). Currently, biologic therapies are used in cases where patients fail conventional medical therapies. If biologic therapies are not available, patients often choose to remain in an unwell state rather than undergo colectomy. Objective. The aim of the study was to evaluate the cost-effectiveness of adalimumab in patients with UC where adalimumab was readily available compared to not available. Methods. A previously validated Markov model was used to simulate disease progression of patients with UC who are corticosteroid-dependent and/or did not respond to thiopurine therapy. Utility scores and transition probabilities between health states were determined by using data from randomized controlled trials and real-life observational studies. Costs were obtained from the Ontario Case Costing Initiative and the Alberta Health Schedule of Medical Benefits. Results. The incremental cost-effectiveness ratios for readily available adalimumab treatment of UC were $40,000 and $59,000 per quality-adjusted life year, compared with ongoing medical therapy in an unwell state, at 5-year and 10-year treatment time horizons, respectively. Conclusion. Considering real-life patient preferences to avoid colectomy, adalimumab is cost-effective according to a willingness-to-pay threshold of $80,000 for treatment of UC.
