Assessment of Racial Misclassification Among American Indian and Alaska Native Identity in Cancer Surveillance Data in the United States and Considerations for Oral Health: A Systematic Review.

Introduction: Misclassification of American Indian and Alaska Native (AI/AN) peoples exists across various databases in research and clinical practice. Oral health is associated with cancer incidence and survival; however, misclassification adds another layer of complexity to understanding the impact of poor oral health. The objective of this literature review was to systematically evaluate and analyze publications focused on racial misclassification of AI/AN racial identities among cancer surveillance data.

Native American Community Perspectives on Oral Health Access: Understanding the Impact of Rurality.

Purpose: Oral health disparities related to access persist for American Indian/Alaska Native (AI/AN) communities compared to the general population, especially in rural areas of the United States. The objective of this study was to better understand community perspectives of oral health, how rurality impacts access to care, and attitudes towards the implementation of dental therapists in Oklahoma, particularly among the AI/AN population.

Methods: A descriptive, observational study design was utilized.

Recovery of Smelter-Impacted Peat and Sphagnum Moss: a Microbial Perspective.

Peatlands store approximately one-half of terrestrial soil carbon and one-tenth of non-glacial freshwater. Some of these important ecosystems are located near heavy metal emitting smelters. To improve the understanding of smelter impacts and potential recovery after initial pollution controls in the 1970s (roughly 50 years of potential recovery), we sampled peatlands along a distance gradient of 134 km from a smelter in Sudbury, Ontario, Canada, an area with over a century of nickel (Ni) and copper (Cu) mining activity.

Patient experiences of remote care in a pain service during a pandemic.

Background: In March 2020, Pain Management Services were obliged to cease face-to-face consultations. This abrupt change, in line with recommendations from the British Pain Society, aimed to protect patients and staff and allowed resource re-allocation. Pain services were obliged to switch to remote consultations using Video Tele-Conferencing Technology (VTC) and Remote Consultations (RC) either through telephone or video calls using a variety of media and software applications.

Oral Health Workforce and American Indian and Alaska Native Communities: a Systematic Review.

Objective: Understanding the oral health workforce representing and serving American Indian and Alaska Native (AI/AN) communities is vital to improving community dental health outcomes. No systematic review of recent published literature on the oral health workforce among this population has been completed.

Methods: We conducted a systematic review of published literature examining the oral health workforce representing and serving AI/AN communities in the USA.

Oral Health Policy and Improvement Strategies in Oklahoma.

Oklahoma an ethnically, financially and geographically diverse population has unique oral health care challenges. These challenges include poor overall oral health, inadequate oral health coverage, significant physical access to care barriers and a shortage of oral health care workers. Just as the oral health care barriers are diverse, so are the potential solutions.

Treatment consolidation after vertical integration: Evidence from outpatient procedure markets.

Hospital ownership of physician practices has grown across the US, and these strategic decisions seem to drive higher prices and spending. Using detailed physician ownership information and a universe of Florida discharge records, we show novel evidence of hospital-physician integration foreclosure effects within outpatient procedure markets. Following hospital acquisition, physicians shift nearly 10% of their Medicare and commercially insured cases away from ambulatory surgery centers (ASCs) to hospitals and are up to 18% less likely to use an ASC at all.

Immersive interactive virtual walking reduces neuropathic pain in spinal cord injury: findings from a preliminary investigation of feasibility and clinical efficacy.

Chronic neuropathic pain (NP) is a common and often debilitating secondary condition for persons with spinal cord injury (SCI) and is minimally responsive to existing pharmacological and nonpharmacological treatments. The current preliminary investigation describes the feasibility and initial comparative efficacy of an interactive virtual reality walking intervention, which is a novel extension of visual feedback/illusory walking therapies shown to reduce SCI NP. Virtual reality walking intervention builds on previous research by, for the first time, allowing individuals with SCI NP to volitionally control virtual gait to interact with a fully immersive virtual environment.

Suppressing peatland methane production by electron snorkeling through pyrogenic carbon in controlled laboratory incubations.

Northern peatlands are experiencing more frequent and severe fire events as a result of changing climate conditions. Recent studies show that such a fire-regime change imposes a direct climate-warming impact by emitting large amounts of carbon into the atmosphere. However, the fires also convert parts of the burnt biomass into pyrogenic carbon.

Removing Medicare's outpatient ban and Medicare and private surgical trends.

Objectives: To examine changes in hospital outpatient surgery trends and case mix for Medicare and privately insured patients needing total knee arthroplasty (TKA) following Medicare's removal of TKA from its Inpatient Only list on January 1, 2018.

Study Design: A retrospective analysis of all hospital discharge records in Florida from 2012 through 2018.

Methods: We tracked inpatient vs outpatient performance of TKAs at the state and hospital levels.

When driving hurts: characterizing the experience and impact of driving with back pain.

Objectives: Driving is one of the most widespread aspects of daily living to people in the United States and is an active process that requires various cognitive functions, such as attention. Chronic low back pain (CLBP) is one of the more prevalent and costly health conditions in the world, with individuals who report CLBP also reporting significant impairment across different domains of daily life both physically and cognitively. However, despite the prevalence of these two constructs, research detailing the experience of driving in pain remains largely underrepresented.

Development and validation of a daily Injustice Experience Questionnaire.

Background: Patterns of cognitive appraisal related to chronic pain may manifest differentially across time due to a variety of factors, but variability of injustice appraisals across time has not been examined. The current study details the validation of a brief, daily version of the Injustice Experience Questionnaire (IEQ), which measures injustice appraisals related to the experience of pain and disability.

Methods: Injustice Experience Questionnaire items were adapted for daily use and evaluated using cognitive interviews, and the resulting measure was administered for 10 days to two Internet-based samples of US adults with chronic lower back pain.

A case study of an influenza vaccination program for health care workers in Vietnam.

Background: In 2017, the Vietnam Ministry of Health conducted a demonstration project to introduce seasonal influenza vaccination to health care workers. A total of 11,000 doses of influenza vaccine, single-dose prefilled syringes, were provided free to HCWs at 29 selected hospitals, clinics, and research institutes in four provinces: Hanoi, Khanh Hoa, Dak Lak and Ho Chi Minh City.

Methods: Before the campaign, a workshop was organized to discuss an implementation plan including technical requirements, cold chain, uptake reporting, and surveillance for adverse events following immunization.

Peatland Microbial Community Composition Is Driven by a Natural Climate Gradient.

Peatlands are important players in climate change-biosphere feedbacks via long-term net carbon (C) accumulation in soil organic matter and as potential net C sources including the potent greenhouse gas methane (CH). Interactions of climate, site-hydrology, plant community, and groundwater chemical factors influence peatland development and functioning, including C dioxide (CO) and CH fluxes, but the role of microbial community composition is not well understood. To assess microbial functional and taxonomic dissimilarities, we used high throughput sequencing of the small subunit ribosomal DNA (SSU rDNA) to determine bacterial and archaeal community composition in soils from twenty North American peatlands.

Akt/survivin pathway inhibition enhances the apoptotic cell death-induced by alpha-santalol in human prostate cancer cells.

We have shown previously that alpha-santalol, a major component of sandalwood oil inhibits growth of cultured prostate cancer cells in vitro by causing apoptosis, but the mechanism of cell death is not fully elucidated. The present study was undertaken to investigate the role of PI3K/Akt/survivin pathway in alpha-santalol-induced apoptosis employing cultured LNCaP and PC-3 human prostate cancer cells. Treatment of prostate cancer cells with alpha-santalol (20, 40 μM) resulted in the down regulation of survivin and p-AKT (s-473) expression and statistically significant reduction in total survivin levels as evidenced by survivin ELISA assay.

Acceptability of seasonal influenza vaccines among health care workers in Vietnam in 2017.

Introduction: A demonstration project in Vietnam provided 11,000 doses of human seasonal influenza vaccine free of charge to healthcare workers (HCWs) in 4 provinces of Vietnam. Through this project, we conducted an acceptability survey to identify the main reasons that individuals chose to be vaccinated or not to inform and improve future immunization activities.

Methods: We conducted a descriptive cross-sectional survey from May to August 2017 among HCWs at 13 selected health facilities.

Supporting national immunization technical advisory groups (NITAGs) in resource-constrained settings. New strategies and lessons learned from the Task Force for Global Health's Partnership for influenza vaccine introduction.

National Immunization Technical Advisory Groups (NITAGs) are multidisciplinary national experts who provide independent, evidence-informed vaccine policy recommendations to national health authorities. An essential NITAG function is to ensure that these decisions are grounded in the best available evidence generated through a systematic, transparent process. However, in many low- and middle-income countries (LMICs), experience with this decision making method is limited.

Right and left ventricular interaction in pulmonary hypertension: Insight from velocity vector imaging.

Objective: To evaluate whether global peak systolic strain (PSS) and peak systolic strain rate (PSSR) derived from velocity vector imaging (VVI) allow early recognition of regional and global right ventricular (RV) dysfunction and the impact of this on left ventricular (LV) function in patients with pulmonary hypertension (PHT).

Background: RV function is an important determinant of prognosis in patients with heart failure, pulmonary hypertension, heart transplant, and congenital heart diseases. However, evaluation of the right ventricle is often limited by its complex geometry and inadequate visualization of RV free wall.

Nanotechnology and Health.

: Potential adverse health effects associated with exposure to engineered or synthesized nanomaterials have not been reported in humans; however, there is accumulating evidence from animal studies that exposure to some nanomaterials is harmful. While there is uncertainty as to the likelihood, frequency, and intensity of exposures experienced by those working around engineered nanoparticles, the American College of Occupational and Environmental Medicine has developed this guidance document for occupational medicine physicians and their colleagues to offer prudent preventive recommendations on the topics of exposure monitoring, exposure controls, and medical surveillance.
