Empowering Health Care Workers on Social Media to Bolster Trust in Science and Vaccination During the Pandemic: Making IMPACT Using a Place-Based Approach.

BACKGROUND: Given the widespread and concerted efforts to propagate health misinformation on social media, particularly centered around vaccination during the pandemic, many groups of clinicians and scientists were organized on social media to tackle misinformation and promote vaccination, using a national or international lens. Although documenting the impact of such social media efforts, particularly at the community level, can be challenging, a more hyperlocal or "place-based approach" for social media campaigns could be effective in tackling misinformation and improving public health outcomes at a community level. OBJECTIVE: We aimed to describe and document the effectiveness of a place-based strategy for a coordinated group of Chicago health care workers on social media to tackle misinformation and improve vaccination rates in the communities they serve. METHODS: The Illinois Medical Professionals Action Collaborative Team (IMPACT) was founded in March 2020 in response to the COVID-19 pandemic, with representatives from major academic teaching hospitals in Chicago (eg, University of Chicago, Northwestern University, University of Illinois, and Rush University) and community-based organizations. Through crowdsourcing on multiple social media platforms (eg, Facebook, Twitter, and Instagram) with a place-based approach, IMPACT engaged grassroots networks of thousands of Illinois health care workers and the public to identify gaps, needs, and viewpoints to improve local health care delivery during the pandemic. RESULTS: To address vaccine misinformation, IMPACT created 8 "myth debunking" infographics and a "vaccine information series" of 14 infographics that have generated >340,000 impressions and informed the development of vaccine education for the Chicago Public Libraries. IMPACT delivered 13 policy letters focusing on different topics, such as health care worker personal protective equipment, universal masking, and vaccination, with >4000 health care workers signatures collected through social media and delivered to policy makers; it published over 50 op-eds on COVID-19 topics in high-impact news outlets and contributed to >200 local and national news features. Using the crowdsourcing approach on IMPACT social media channels, IMPACT mobilized health care and lay volunteers to staff >400 vaccine events for >120,000 individuals, many in Chicago's hardest-hit neighborhoods. The group's recommendations have influenced public health awareness campaigns and initiatives, as well as research, advocacy, and policy recommendations, and they have been recognized with local and national awards. CONCLUSIONS: A coordinated group of health care workers on social media, using a hyperlocal place-based approach, can not only work together to address misinformation but also collaborate to boost vaccination rates in their surrounding communities.

Community Versus Hospital Opioid-Related Overdose Deaths in Illinois.

OBJECTIVE: To better understand approaches to reducing mortality from the opioid epidemic, we analyzed in-hospital versus community opioid-related overdose deaths in Illinois. METHODS: We used data from the Statewide Unintentional Drug Overdose Reporting System (July 2017 through December 2018) to identify deaths that occurred in hospitals and communities (ie, homes or public spaces). We used census tract-level data for 34 Illinois counties to create bivariate mapping by overdose death rates. We used logistic regression to analyze the association of demographic and overdose characteristics with the likelihood of death in a hospital versus a community. RESULTS: During the study period, 2833 opioid-related overdose deaths occurred in 24 Illinois counties, 655 (23.1%) of which occurred in the hospital; of 2178 community deaths, 1888 (86.7%) occurred in the same census tract as the decedent's recorded residence and 1285 (59.0%) occurred in the decedent's home. Non-Hispanic Black people were 1.63 (95% CI, 1.27-2.10) times more likely than non-Hispanic White people to die in a hospital. Decedents from suburban Cook County and other Chicago suburban counties were significantly more likely to die in the hospital than decedents from Chicago or other Illinois counties. Documentation of a previous overdose, history of opioid use, and having bystanders present were significantly associated with hospital deaths. Evidence of a rapid overdose, fentanyl present, or prescription opioids were significantly associated with deaths in a community. CONCLUSIONS: The high number of opioid-related overdose deaths in the community illustrates the need to decriminalize illicit drug use and facilitate treatment seeking. Establishing supervised safe consumption sites may have the biggest effect in reducing the number of opioid-related overdose deaths.

A Case for Risk Stratification in Survivors of Firearm and Interpersonal Violence in the Urban Environment.

The emergency department (ED) serves as the main source of care for patients who are victims of interpersonal violence. As a result, emergency physicians across the nation are at the forefront of delivering care and determining dispositions for many at-risk patients in a dynamic healthcare environment. In the majority of cases, survivors of interpersonal violence are treated and discharged based on the physical implications of the injury without consideration for risk of reinjury and the structural drivers that may be at play. Some exceptions may exist at institutions with hospital-based violence intervention programs (HVIPs). At these institutions, disposition decisions often include consideration of a patient's risk for repeat exposure to violence. Ideally, HVIP services would be available to all survivors of interpersonal violence, but a variety of current constraints limit availability. Here we offer a scoping review of HVIPs and our perspective on how risk-stratification could help emergency physicians determine which patients will benefit most from HVIP services and potentially reduce re-injury secondary to interpersonal violence.

Therapeutic Potential of Endothelial Progenitor Cells in the Field of Orthopaedics.

Inadequate blood supply frequently impedes the viability of tissue-engineered constructs in the initial phase after implantation, and can lead to improper cell integration or cell death. Vascularization using stem cells has continued to evolve as a potential solution to this problem. In this review, we summarize studies that utilize endothelial progenitor cells (EPCs) for musculoskeletal regeneration. This review will also highlight recent concepts for EPC identification in conjunction with the development of EPC biology research. EPCs promote bone regeneration in animal models through a variety of mechanisms. By differentiating toward endothelial cell lineages and osteoblasts, EPCs stimulate vasculogenesis, angiogenesis and osteogenesis. Moreover, EPCs influence supporting cells through the secretion of growth factors and cytokines. Phase I/II clinical trials have applied circulating CD34+ cells/EPCs to nonunion bone fractures and have exhibited promising results including accelerated bone healing. Similar mechanisms of angiogenesis and osteogenesis are proposed for anterior cruciate ligament (ACL) ruptured tissue derived CD34+ cells, and thus EPCs have implied a critical role at the site of tendon-bone integration. EPCs are an emerging strategy among other cell-based therapies in the field of orthopaedics for the promotion of musculoskeletal regeneration.

Rates of firearm homicide by Chicago region, age, sex, and race/ethnicity, 2005-2010.

BACKGROUND: The United States reports the highest levels of firearm homicide incidences compared to other high income countries, and the focus and causes of these incidences within the US differ by demographic characteristics and location such as urban versus rural environment. Despite these findings, few studies have published on rates varied by region within a city. OBJECTIVE: This study aims to provide descriptive analysis of the rates of firearm homicide by age, sex, and race/ethnicity in each of the seven City of Chicago regions, and to determine if the rates of firearm homicide differ by demographics among the seven City of Chicago regions. METHODS: The Illinois Violent Death Reporting System conducts routine surveillance of violent deaths. Decedents were selected according to the following criteria: manner of death was homicide, weapon type was firearm, and location of injury that led to death was the City of Chicago. Location of injury was broken down by regions: North, Northwest, Center, West, South, Southwest, and Far South. Multiyear rates per 100,000 and corresponding 95% confidence intervals were calculated. RESULTS: There were 2,254 victims of homicide by firearm in the City of Chicago. The overall rate across Chicago for all demographics was 12.9 (12.1-13.5 per 100,000) with an average age of 27.4. The highest age group (20-24) for firearm homicide rates was 43.2 (39.7-46.7) per 100,000. For the youngest age group (10-14), only the Southwest (3.3-10.4) region reported any firearm incidence. The 20 to 24 age group reported the highest rates of all age groups within the South (107.9-151.7), West (80.3-108.2), and Far South (69.6-105.3) regions, whereas the North and Northwest reported the lowest rates for all regions by age. Black firearm homicide rates were 33.5 (31.9-35.1) per 100,000 versus Hispanic and non-Hispanic white firearm homicide rates of 8.5 (7.7-9.3) and 1.2 (1-1.5) per 100,000, respectively. Lastly, the West reported the highest firearm rates at 29.1 (657). CONCLUSION: In conclusion, Chicago is a large city that has high variation in firearm homicide rates among its constituent regions; therefore, an overall firearm homicide rate for the city of Chicago as a whole is not an accurate representation of the true nature of firearm homicides. Policy implementation may be made more effective by providing more regional analysis and targeted interventions via multipronged initiatives to help reduce future firearm rates, and funding for issues that address systemic poverty and adequate access to care and medical facilities. LEVEL OF EVIDENCE: Epidemiologic study, level IV.

Transitions of Care in an Era of Healthcare Transformation.

In the practice of modern emergency medicine (EM), transitions of care (TOC) have taken a prominent role, and during this time of healthcare reform, TOC has become a focal point of improvement initiatives across the continuum of care. This review includes a comprehensive examination of various regulatory, accreditation, and policy-based elements with which EM physicians interact in their daily practice. The content is organized into five domains: Accreditation Council for Graduate Medical Education (ACGME), The Joint Commission, Affordable Care Act, National Quality Forum (NQF), and accountable care organizations. This review is meant to be a synthesis of TOC material, tailored for EM physicians and the teams that make these departments run. We include (1) relevant current regulations and standards from various entities that are most likely to affect the day-to-day practice of EM; (2) examination of the consequences of these regulations and standards and how they can be used to shape EM practice and clinical decision making; and (3) comparison of interventions aimed at improving TOC, including evidence from current literature, practical examples, and proposals. Emergency departments must develop, implement, and monitor TOC programs and processes that can facilitate seamless and efficient care as patients transfer between settings. This report provides a framework for that effort and is designed to help EM physicians continue to take the lead in improving TOC to help shape the future of modern practice.

Surgical Treatment of Acute Grade III Medial Collateral Ligament Injury Combined With Anterior Cruciate Ligament Injury: Anatomic Ligament Repair Versus Triangular Ligament Reconstruction.

PURPOSE: The purpose of this study was to evaluate the clinical results of medial collateral ligament (MCL) anatomic ligament repair (ALR) and triangular ligament reconstruction (TLR) in treating acute grade III MCL injury with respect to imaging and functional results. METHODS: Between January 2009 and October 2011, a total of 69 patients with an acute grade III MCL tear combined with an anterior cruciate ligament tear were divided into 2 groups: those who underwent ALR and those who underwent TLR. Single-bundle anterior cruciate ligament reconstruction was also performed in all patients. A radiographic stress-position imaging test was performed to evaluate excessive medial opening of the knee. In addition, the Slocum test was carried out to assess anteromedial rotatory instability before surgery and at follow-up. The subjective symptoms and functional outcomes were evaluated preoperatively and postoperatively with International Knee Documentation Committee (IKDC) assessment. RESULTS: Sixty-four patients with a mean follow-up period of 34 months were included in the final analysis. The measurement results for medial opening at the last follow-up appointment decreased significantly from the pretreatment measurements and fell within the normal range, without a statistically significant difference between the 2 groups (P > .05). The overall incidence of anteromedial rotatory instability was reduced to 21.9% compared with 62.5% preoperatively. However, the incidence of anteromedial rotatory instability in the TLR group (9.4%) decreased significantly compared with that in the ALR group (34.4%) (P < .05). All patients' IKDC subjective scores significantly improved after surgery. No statistically significant difference was found between the 2 groups at the last follow-up (P > .05). The comparison of IKDC extension and flexion deficit scores between the 2 groups showed no significant differences. Eleven patients in the ALR group and 4 in the TLR group complained of medial knee pain. The comparison between the 2 groups showed no significant difference (P > .05). CONCLUSIONS: The clinical outcomes of this study showed that no major difference existed in the ALR and TLR groups based on IKDC scores and medial opening evaluations in the short-term. However, TLR offered better rotatory stability than ALR at final follow-up. LEVEL OF EVIDENCE: Level II, lesser-quality randomized controlled trial.

The role of stem cells and tissue engineering in orthopaedic sports medicine: current evidence and future directions.

The use of stem cell therapies for the treatment of orthopaedic injuries continues to advance. The purpose of this review was to provide an update of the current role and future directions of stem cell strategies in sports medicine. The application of cell-based treatments in the sports medicine arena has expanded in recent years. Promising preclinical results have led to translation of these novel therapies into the clinical setting. Early well-designed comparative clinical studies have also shown positive outcomes. Despite significant advances in this arena, there remains a need for additional high-powered and well-designed clinical trials to confirm the safety and efficacy of treatment.

Evaluation of hip pain in young adults.

Hip pain is a common complaint in the young, athletic patient population. Primary, intra-articular sources of hip pain are becoming increasingly recognized by primary care providers and sports medicine specialists. Prior to deciding among the various treatment options for the many sources of hip pain in the athletic patient population, the clinician must be able to recognize and accurately diagnose the underlying pathology. Advances in imaging modalities and our understanding of the pathophysiology have improved our ability to accurately understand and diagnose the source of hip pain in this patient population. This review presents a comprehensive strategy for the workup and diagnosis of young, athletic patients presenting with hip pain, and provides the sports medicine specialist with the tools to correlate the patient's history, physical examination, and imaging findings and to treat these challenging patients.
