Transforaminal lumbar interbody fusion with an expandable interbody device: Two-year clinical and radiographic outcomes.

Background: The use of interbody cages as an adjunct to lumbar spinal fusion remains an important technique to enhance segmental stability, promote solid arthrodesis, maintain neuroforaminal decompression, and preserve/improve segmental lordosis. Appropriate segmental lumbar lordosis and sagittal balance is well-known to be critical for long-term patient outcomes. This study sought to evaluate the radiographic and clinical results of TLIF in patients using an articulating, expandable cage. Primary endpoint was clinical and radiographic outcomes, including complications, at 12 and 24 months. Methods: A total of 37 patients underwent open single-level or 2-level TLIF by a single surgeon using an expandable cage with concomitant bilateral pedicle screws and posterolateral arthrodesis. Clinical outcomes included ODI and VAS for back and legs. Radiographic outcomes included pelvic incidence and tilt, lumbar and segmental lordoses, and disc height at the operative level(s). All outcomes were collected at baseline, 2-weeks, 6-weeks, 3-months, 6-months, 12-months, and 24-months postop. Results: A total of 28 patients were available for analysis. Nine patients failed to follow-up at 24 months. Mean ODI scores showed significant improvement, from pre-to-postoperative at 24 months (55%; p<.0001). VAS for back and legs was significantly lower at 24 months on average by 72 and 79%, respectively (p<.0001 for both). Both segmental and lumbar lordoses significantly improved by 5.3° and 4.2° (p<.0001 and p=.049), respectively. Average disc height improved by 49% or 6.1 mm (p<.001). No device-related complications nor instances of measured subsidence. One patient had a superficial infection, and another had an intraoperatively repaired incidental durotomy. Conclusions: The use of an expandable cage contributed to improvement in both segmental and lumbar lordosis with no reported complications at 24-month follow-up. All clinical measures significantly improved as well. The expandable cage design represents an effective and safe option to increase cage size and allow significant segmental lordosis correction.

Evaluation of a pilot emergency department linkage to care program for patients previously diagnosed with Hepatitis C.

There is a significant number of Emergency Department (ED) patients with known chronic hepatitis C virus (HCV) infection who have not been treated with directly acting antivirals. We implemented a pilot ED-based linkage-to-care program to address this need and evaluated the impact of the program using the HCV Care Continuum metrics. Between March 2015 and May 2016, dedicated patient care navigators identified HCV RNA-positive patients in an urban ED and offered expedited appointments with the on-site viral hepatitis clinic. Patient demographics and care continuum outcomes were abstracted from the EMR and analysed to determine significant factors influencing linkage-to-care (LTC) and treatment initiation rates. The ED linkage-to-care program achieved a 43% linkage-to-care rate (165/384), 22% treatment rate (84/384) and 16% sustained virologic response rate (63/384). Significant associations were found between linkage-to-care and increasing age (OR = 1.03), Medicare insurance (OR = 2.21) and having a primary care physician (PCP) (OR = 4.03). For patients who were linked, the odds of initiating treatment were also positively significantly associated with increasing age (OR = 1.04) and having a PCP (OR = 2.77). For patients who initiated treatment, the odds of sustained virologic response were marginally associated with having a PCP (OR = 4.92).Our ED linkage-to-care program utilized care coordination to successfully link nearly half of approached HCV RNA-positive patients to care. This design can be feasibly replicated by other EDs given limited non-clinical training required for linkage-to-care staff. Adoption of similar programs in other EDs may improve the rates of LTC and treatment initiation for previously diagnosed HCV patients.

Human-centered design development of mHealth patient-to-peer referral tool in the emergency department.

Background: Given the steady increase of emergency department (ED) visits related to opioid overdoses, this study aims to determine the design and usability of an ED-centered mHealth patient-to-peer referral prototype tool that allows patients to refer peers to comprehensive HIV/HCV and opioid misuse prevention services. Methods: Two iterative focus group discussion (FDG) sessions and one use-case session were conducted. Eligible participants who were ≥18 years, had a history of injection drug use (IDU), and had utilized the ED in the past year were recruited through the distribution of flyers at the study institution, including the study ED. Human-centered design process was completed by using participant feedback on perceived utility, usability/accessibility, tool design, and clarity/readability to fine-tune prototype version and drive subsequent discussion sessions. Results: Sixteen consented individuals participated in at least one of the sessions. Feedback revealed that participants favored the inclusion of the webpage link on the referral card as means to bypass QR code if needed, more descriptions highlighting the exact services offered, and the fact that no personal information was required to complete the referral process. The prototype underwent several adjustments between user-centered FDG sessions, which ultimately ended in including features such as an online webpage with educational videos, SMS text-message communication system, and QR code usage into the final patient-to-peer referral tool prototype. Conclusion: The findings of this study suggest a human-centered designed patient-to-peer referral tool could be a feasible approach to linking community members at risk of IDU to HIV/HCV and opioid use-related preventive services from ED patients.

Lack of race/ethnic minority representation in ulnar collateral ligament reconstruction in baseball athletes: a systematic review.

OBJECTIVES: To assess the reporting and representation of ethnic and racial minorities in comparative studies of ulnar collateral ligament (UCL) injuries and treatment in baseball athletes. METHODS: A systematic review of the literature was conducted using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The literature search was conducted by two independent reviewers using the PubMed, Scopus, and Cochrane Library databases. Studies were included if they were UCL of the elbow clinical comparative studies, including randomized clinical trials, cohort studies, case series, and epidemiological studies. Studies were excluded if they were related to ulnar collateral ligament of the thumb, lateral ulnar collateral ligament of the elbow, biomechanical studies, non-surgical studies, non-baseball studies, and systematic reviews and meta-analyses. The Methodological Index for Non-Randomized Studies (MINORS) criterion was used to assess quality of studies included. RESULTS: A total of 108 studies were included for analysis, of which only one reported race and ethnicity in their demographics. Additionally, of the 108 studies included, only four reported Country of Origin, a subset of Race and Ethnicity, in their demographics. CONCLUSION: Race and Ethnicity demographics are scarcely reported in comparative studies evaluating ulnar collateral ligament reconstruction. Future studies evaluating similar populations should strongly consider reporting racial and ethnic demographics as this may provide clarity on any potential effect these might have on post-surgical outcomes, particularly in high-level pitchers.

A pilot study of a mixed-method approach to design an ED-based peer mHealth referral tool for HIV/HCV and opioid overdose prevention services.

BACKGROUND: The intersecting epidemics of opioid misuse, injection drug use, and HIV/HCV have resulted in record overdose deaths and sustained high levels of HIV/HCV transmissions. Literature on social networks suggests opportunities to connect people who use drugs (PWUD) and their peers to HIV/HCV and opioid overdose prevention services. However, little evidence exists on how to design such peer referral interventions in emergency department (ED) settings. METHODS: A mixed-method study was conducted to assess the feasibility of an mHealth-facilitated 'patient to peer social network referral program' for PWUD. In-depth interviews (IDIs) and quantitative surveys were conducted with urban ED patients (n = 15), along with 3 focus group discussions (FGDs) (n = 19). RESULTS: Overall, 34 participants were enrolled (71 % males, 53 % Black). 13/15 IDI participants reported a history of opioid overdose; all had witnessed overdose events; all received HIV/HCV testing. From survey responses, most would invite their peers for HIV/HCV testing and naloxone training; and anticipated peers to accept referrals (HIV: 60 %, HCV: 73 %, naloxone: 93 %). Qualitative data showed PWUD shared health-related information with each other but preferred word of mouth rather than text messages. Participants used smartphones regularly and suggested using Internet advertising for prevention services. Participants expressed enthusiasm for ED-based peer mHealth referral platform to prevention services, as well as referring their peers to proposed services, with monetary incentives. CONCLUSION: ED-based peer referral intervention to HIV/HCV testing and naloxone training was viewed favorably by PWUD. Frequent smartphone use among PWUD suggests that the medium could be a promising mode for peer referral.

Racial/Ethnic and Sex Representation in US-Based Clinical Trials of Hearing Loss Management in Adults: A Systematic Review.

Importance: Although the National Institutes of Health (NIH) mandated the inclusion and reporting of women and racial or ethnic minority groups in NIH-funded research in 1993, little is known regarding the representation of women and racial or ethnic minority groups in trials that investigate hearing loss management. Objective: To assess sex and racial/ethnic representation in US-based clinical trials of hearing loss management in an adult population. Data Sources: Pertinent studies were identified using search strategies in PubMed, Embase, and ClinicalTrials.gov. Study Selection: Our search strategy yielded 6196 studies. We included prospective studies that were written in English, performed in the US, and evaluated hearing loss management in adults, including amplification devices, such as hearing aids or assistive listening devices, cochlear implants, aural rehabilitation, and therapeutics. Given its prevalence, only studies that addressed bilateral sensorineural hearing loss were included. Data Extraction and Synthesis: Data from 125 studies were extracted. The Preferred Reporting Items for Systematic Reviews and Meta-analyses diagram for systematic reviews was used for abstracting data. The guidelines were applied using independent extraction by multiple observers. Results: Among 125 clinical studies performed from January 1990 to July 2020 regarding hearing loss management, only 16 (12.8%) reported race/ethnicity, and 88 (70.4%) reported sex. Of the 16 studies that reported race/ethnicity, only 5 included more than 30% non-White representation. Among the 88 articles that reported sex, 44 (35.2%) reported more than 45% female representation. While the mean number of participants included in the observed trials was 80 (range, 7-644), the median number of participants from racial or ethnic minority groups in studies that reported race/ethnicity was 9 (range, 1-77), and a median of 12 female participants were included in studies with a numerical breakdown by sex. A mean of 41% (range, 1.55%-77.5%) of participants were female among studies that reported sex, and a mean of 30% (range, 1.96%-100%) of participants were from racial or ethnic minority groups among the 16 studies that reported race/ethnicity. Reporting of race/ethnicity varied substantially by funding source and journal type, while reporting by sex differed only by journal type. Conclusions and Relevance: Studies investigating hearing loss management do not adequately reflect the US population. A closer examination of the inclusion of diverse adults in clinical research associated with hearing health may work to ameliorate disparities and contribute to the development of tailored interventions that address the needs of an increasingly diverse US population.
