    Abstract Context.—: The FilmArray Meningitis/Encephalitis (ME) panel is the first US Food and Drug Administration-cleared multiplex polymerase chain reaction panel for the detection of central nervous system infections. While the assay's performance characteristics have been described, the real-world significance of positive results has not been fully characterized.
    Objective.—: To evaluate the clinical significance of positive ME panel results in a tertiary care medical center in New York, New York.
    Design.—: Four physicians independently performed retrospective clinical assessments of all positive ME panel results at Columbia University Irving Medical Center, including the Children's Hospital of New York, during an 18-month period. Each reviewer determined the likelihood of central nervous system infection for all cases and whether cases fit Brighton diagnostic criteria for meningitis, encephalitis, or meningoencephalitis.
    Results.—: Among 119 cases, there was 75% positive agreement (95% CI, 54%-89%) between ME panel results and clinical consensus, which varied among panel targets.
    Conclusions.—: The ME panel showed good agreement with expert clinical consensus for patients presenting with acute meningitis/encephalitis. Factors contributing to clinically insignificant ME positive results included low pretest probability, traumatic lumbar puncture, specimen contamination, and detection of incidental viral targets such as human herpesvirus 6. Notably, the ME panel detected more than twice the number of cases of bacterial meningitis detected by culture alone, particularly among patients receiving empiric antimicrobial therapy before lumbar puncture. Appropriate test use and contextual interpretation of results are critical to leveraging the advantages of the platform while avoiding potential pitfalls.

    Abstract Objective: The objective of this study was to show that degenerative lumbar magnetic resonance imaging findings variably increase discography pain by level.
    Methods: Lumbar discography and magnetic resonance imaging of 736 patients were retrospectively reviewed. Univariate/multivariate logistic regressions calculated the odds ratio (OR) (95% confidence interval, P < 0.05).
    Results: L3-4 multivariate regression OR for a degenerative disc is 9.9; for bulge, 10.9; for annular tear, 38.9; for herniation, 51.5; and for degenerative facet, 2.158. Endplate changes were not significant. L4-5 OR for a degenerative disc is 4.52; for bulge, 13.74, for tear, 19.13; for herniation, 28.65; for endplate edema, 3.47; and fatty change, 3.84. Degenerative facet ORs were not significant. L5-S1 OR for a degenerative disc is 6.86; for bulge, 5.65; for tear, 40.56; and for herniation, 77.98. Endplate changes and degenerative facet OR's were not significant.
    Conclusions: Advancing degeneration increases pain at L5-S1 followed by L3-4. Endplate signal is significant only at L4-5.

    Abstract Incretin-based therapies are effective glucose-lowering drugs that have an increasing role in the treatment of type 2 diabetes because of their efficacy, safety, and ease of use. Both glucagon-like peptide-1 receptor agonists and dipeptidyl peptidase-4 inhibitors are commonly used for glycemic control as adjuncts to metformin, other oral antiglycemic agents, or insulin. Glucagon-like peptide-1 receptor agonists may have additional effects, such as weight loss, that may be advantageous in obese patients. There is a large body of evidence from randomized controlled clinical trials supporting the cardiovascular safety of dipeptidyl peptidase-4 inhibitors and some glucagon-like peptide-1 receptor agonists, at least in the short term. However, concerns have been raised, particularly regarding their safety in patients with heart failure. In this review, the authors provide a brief but practical evidence-based analysis of the use of incretin-based agents in patients with diabetes, their efficacy, and cardiovascular safety.

    Abstract Objective: As guidelines are evolving towards recommending starting antiretroviral therapy (ART) in all HIV-positive individuals irrespective of clinical and immunological status, HIV programmes will be challenged to manage an increasingly diverse set of patient needs. To support global guideline recommendations for differentiated service delivery, WHO developed consensus definitions for two distinct patient populations: patients presenting with advanced disease and patients who are stable on ART.
    Methods: An expert panel consisting of 73 respondents from 28 countries across all six WHO regions supported the development of these definitions. The panel included clinicians, researchers, programme managers, technical advisors and patient group representatives.
    Results: Patients presenting with advanced disease at presentation to care were defined as CD4 count <200 CD4 cells/mm(3) or WHO Stage III & IV defining illness. Patients stable on ART were defined as those who were receiving ART for at least 1 year with no adverse drug reactions requiring regular monitoring, no current illnesses or pregnancy, a good understanding of lifelong adherence, and evidence of treatment success. Treatment success was defined as two consecutive undetectable viral load measures or, in the absence of viral load monitoring, rising CD4 counts or CD4 counts above 200 cells/mm(3) and an objective adherence measure.
    Conclusions: Patients who are stable on ART should be offered a less intensive care package that can lead to improved outcomes while saving resources, including less frequent clinic visits, out-of-clinic drug refills and reduced laboratory monitoring. This will allow for clinic resources to be directed towards reducing morbidity and mortality among patients presenting with advanced disease.

    Abstract Purpose: The purpose of this study was to calculate the positive predictive value (PPV) of lumbar spine magnetic resonance imaging (MRI) findings for a painful disc using provocative discography.
    Materials and methods: Lumbar spine discography records and prediscography MRIs of 736 patients (2457 discs) who underwent discography for diagnostic purposes from 2003 to 2007 were retrospectively reviewed in an Institutional Review Board-exempt and Health Insurance Portability and Accountability Act-compliant protocol. Each level was identified as having high-intensity zone (HIZ) disc, disc protrusion, disc extrusion, or combination (any herniation type), disc bulge, disc degeneration, and spondylolisthesis. Statistical analysis used a 2 × 2 contingency table of significant discography results for each of the MRI variables to calculate P value and PPV with a confidence interval from a binomial distribution.
    Results: An HIZ disc has a PPV of 0.71 (0.65-0.76, P = 4.31E - 44) for a provocative discography. A disc protrusion has a PPV of 0.79 (0.73-0.83, P = 2.68E - 53). A disc extrusion has a PPV of 0.93 (0.79-0.98, P = 1.34E - 14), a bulge of 0.43 (0.37-0.48, P = 0.002), and a degenerative disc of 0.32 (0.28-0.35, P = 0.08), and spondylolisthesis has a PPV of 0.67 (0.59-0.73, P = 1.70E - 20). A herniation of either type (extrusion or protrusion) has a PPV of 0.80 (0.75-0.84, P = 5.86E - 69).
    Conclusions: Disc herniations and HIZ discs have high predictive value in identifying a pain generator. An extruded disc herniation has the highest PPV for discogenic pain.

    As guidelines are evolving towards recommending starting antiretroviral therapy (ART) in all HIV-positive individuals irrespective of clinical and immunological status, HIV programmes will be challenged to manage an increasingly diverse set of patient needs. To support global guideline recommendations for differentiated service delivery, WHO developed consensus definitions for two distinct patient populations: patients presenting with advanced disease and patients who are stable on ART.An expert panel consisting of 73 respondents from 28 countries across all six WHO regions supported the development of these definitions. The panel included clinicians, researchers, programme managers, technical advisors, and patient group representatives.Patients presenting with advanced disease at presentation to care were defined as CD4 count < 200 CD4 cells/mm(3) or WHO Stage III & IV defining illness. Patients stable on ART were defined as those who were receiving ART for at least 1 year, with no adverse drug reactions requiring regular monitoring, no current illnesses or pregnancy, a good understanding of lifelong adherence, and evidence of treatment success.

    Abstract Background Variation exists in outcomes following out-of-hospital cardiac arrest (OHCA), but whether racial and ethnic disparities exist in post-arrest provision of targeted temperature management (TTM) is unknown. Methods and Results We performed a retrospective analysis of a prospectively collected cohort of patients who survived to admission following OHCA from the Cardiac Arrest Registry to Enhance Survival, whose catchment area represents ~50% of the United States from 2013-2019. Our primary exposure was race/ethnicity and primary outcome was utilization of TTM. We built a mixed-effects model with both state of arrest and admitting hospital modeled as random intercepts to account for clustering. Among 96,695 patients (24.6% Black, 8.0% Hispanic/Latino, 63.4% White), a smaller percentage of Hispanic/Latino patients received TTM than Black or White patients (37.5% vs. 45.0 % vs 43.3%, P < .001) following OHCA. In the mixed-effects model, Black patients (Odds Ratio [OR] 1.153, 95% Confidence Interval [CI] 1.102-1.207, P < .001) and Hispanic/Latino patients (OR 1.086, 95% CI 1.017-1.159, P < .001) were slightly more likely to receive TTM compared to White patients, perhaps due to worse admission neurological status. We did find community level disparity as Hispanic/Latino-serving hospitals (defined as the top decile of hospitals that cared for the highest proportion of Hispanic/Latino patients) provided less TTM (OR 0.587, 95% CI 0.474 to 0.742, P < .001). Conclusions Reassuringly, we did not find evidence of intrahospital or interpersonal racial or ethnic disparity in the provision of TTM. However, we did find inter-hospital, community level disparity. Hispanic/Latino-serving hospitals provided less guideline-recommended TTM after OHCA.
