Effects of high-dose versus standard-dose quadrivalent influenza vaccine among patients with diabetes: A post-hoc analysis of the DANFLU-1 trial.

AIM: High-dose quadrivalent influenza vaccine (QIV-HD) has been shown to be more effective than standard-dose (QIV-SD) in reducing influenza infection, but whether diabetes status affects relative vaccine effectiveness (rVE) is unknown. We aimed to assess rVE on change in glycated haemoglobin [HbA1c (∆HbA1c)], incident diabetes, total all-cause hospitalizations (first + recurrent), and a composite of all-cause mortality and hospitalization for pneumonia or influenza. METHODS: DANFLU-1 was a pragmatic, open-label trial randomizing adults (65-79 years) 1:1 to QIV-HD or QIV-SD during the 2021/22 influenza season. Cox proportional hazards regression was used to estimate rVE against incident diabetes and the composite endpoint, negative binomial regression to estimate rVE against all-cause hospitalizations, and ANCOVA when assessing rVE against ∆HbA1c. RESULTS: Of the 12 477 participants, 1162 (9.3%) had diabetes at baseline. QIV-HD, compared with QIV-SD, was associated with a reduction in the rate of all-cause hospitalizations irrespective of diabetes [overall: 647 vs. 742 events, incidence rate ratio (IRR): 0.87, 95% CI (0.76-0.99); diabetes: 93 vs. 118 events, IRR: 0.80, 95% CI (0.55-1.15); without diabetes: 554 vs. 624 events, IRR: 0.88, 95% CI (0.76-1.01), pinteraction = 0.62]. Among those with diabetes, QIV-HD was associated with a lower risk of the composite outcome [2 vs. 11 events, HR: 0.18, 95% CI (0.04-0.83)] but had no effect on ∆HbA1c; QIV-HD adjusted mean difference: ∆ + 0.2 mmol/mol, 95% CI (-0.9 to 1.2). QIV-HD did not affect the risk of incident diabetes [HR 1.18, 95% CI (0.94-1.47)]. CONCLUSIONS: In this post-hoc analysis, QIV-HD versus QIV-SD was associated with an increased rVE against the composite of all-cause death and hospitalization for pneumonia/influenza, and the all-cause hospitalization rate irrespective of diabetes status.

Elevated plasma apolipoprotein E levels in people living with HIV: Associations with biomarkers and HIV-specific risk factors.

BACKGROUND AND AIMS: Apolipoprotein E (apoE) plays a crucial role in cholesterol metabolism, and high levels of apoE in plasma are associated with cardiovascular disease and all-cause mortality. We aimed to assess if HIV is independently associated with high plasma apoE and to determine HIV-related risk factors for high plasma apoE. METHODS: We included 661 people with HIV (PWH) from the Copenhagen Comorbidity in HIV (COCOMO) study with available measurement of plasma apoE. COCOMO participants were frequency matched 1:1 on age and sex with controls from the Copenhagen General Population Study. High plasma apoE was defined as levels above the 90th percentile (66.2 mg/L). The association between HIV and high plasma apoE was assessed using logistic regression models. Among PWH, both linear and logistic regression models were used to determine HIV-specific risk factors for high plasma apoE. RESULTS: Mean age was 52 years and 89 % were male. Median plasma apoE was 49.0 mg/L in PWH and 43.3 mg/L in controls, p < 0.001. HIV was associated with higher plasma apoE after adjusting for potential confounders, including triglycerides (odds ratio 2.14 [95 % CI: 1.39-3.29], p < 0.001). In PWH, higher plasma apoE was associated with a previous AIDS-defining condition in linear models before adjustment for triglycerides and integrase strand transfer inhibitor use in fully adjusted linear models. CONCLUSIONS: PWH had higher plasma apoE than controls even after adjusting for triglycerides. Further studies are needed to elucidate the clinical impact of high plasma apoE in PWH.

Effectiveness of high-dose versus standard-dose quadrivalent influenza vaccine against recurrent hospitalizations and mortality in relation to influenza circulation: A post-hoc analysis of the DANFLU-1 randomized clinical trial.

OBJECTIVES: To evaluate the relative effectiveness of high-dose quadrivalent influenza vaccine (QIV-HD) versus standard-dose quadrivalent influenza vaccine (QIV-SD) against recurrent hospitalizations and its potential variation in relation to influenza circulation. METHODS: We did a post-hoc analysis of a pragmatic, open-label, randomized trial of QIV-HD versus QIV-SD performed during the 2021-2022 influenza season among adults aged 65-79 years. Participants were enrolled in October 2021-November, 2021 and followed for outcomes from 14 days postvaccination until 31 May, 2022. We investigated the following outcomes: Hospitalizations for pneumonia or influenza, respiratory hospitalizations, cardio-respiratory hospitalizations, cardiovascular hospitalizations, all-cause hospitalizations, and all-cause death. Outcomes were analysed as recurrent events. Cumulative numbers of events were assessed weekly. Cumulative relative effectiveness estimates were calculated and descriptively compared with influenza circulation. The trial is registered at Clinicaltrials.gov: NCT05048589. RESULTS: Among 12,477 randomly assigned participants, receiving QIV-HD was associated with lower incidence rates of hospitalizations for pneumonia or influenza (10 vs. 33 events, incidence rate ratio [IRR] 0.30 [95% CI, 0.14-0.64]; p 0.002) and all-cause hospitalizations (647 vs. 742 events, IRR 0.87 [95% CI, 0.76-0.99]; p 0.032) compared with QIV-SD. Trends favouring QIV-HD were consistently observed over time including in the period before active influenza transmission; i.e. while the first week with a ≥10% influenza test positivity rate was calendar week 10, 2022, the first statistically significant reduction in hospitalizations for pneumonia or influenza was already observed by calendar week 3, 2022 (5 vs. 15 events, IRR 0.33 [95% CI, 0.11-0.94]; p 0.037). DISCUSSION: In a post-hoc analysis, QIV-HD was associated with lower incidence rates of hospitalizations for pneumonia or influenza and all-cause hospitalizations compared with QIV-SD, with trends evident independent of influenza circulation levels. Our exploratory results correspond to a number needed to treat of 65 (95% CI 35-840) persons vaccinated with QIV-HD compared with QIV-SD to prevent one additional all-cause hospitalization per season. Further research is needed to confirm these hypothesis-generating findings.

The Interplay between Adipose Tissue Properties and Levels of NT-proBNP in People with HIV.

Objective: We aimed to assess the association between low N-terminal pro-brain natriuretic peptide (NT-proBNP) and body mass index (BMI), adipose tissue distribution, adiponectin, and HIV-specific risk factors among people with HIV (PWH). Methods: We included 811 PWH with measurement of height, weight and waist circumference, blood samples analyzed for NT-proBNP, and visceral-(VAT) and subcutaneous (SAT) adipose tissue areas measured from CT-scans. Low concentrations of NT-proBNP were defined as concentrations below the limit of quantification (5.9 pmol/L). Associations were explored with multivariable logistic regression analyses adjusted for relevant confounders. Results: We identified 471 (58%) individuals with low concentrations of NT-proBNP. Increasing BMI was associated with higher odds of low NT-proBNP (adjusted OR (aOR) 1.06 (95% CI: 1.01-1.11) per 1 kg/m2). Central obesity and large areas of VAT were associated with higher odds of low NT-proBNP (aOR 1.66 (1.16-2.36) and aOR 1.69 (1.09-2.62), respectively). Higher adiponectin was associated with lower odds of low NT-proBNP (aOR 0.86 (0.79-0.95) per 10% increase). No associations were found between low NT-proBNP and HIV-specific risk factors. Conclusions: In PWH, low NT-proBNP is associated with an adverse adipose tissue profile with high BMI, central obesity, accumulation of VAT, and low adiponectin.

Peripheral Artery Disease and Markers of Endothelial Dysfunction and Platelet Activation in People With HIV.

BACKGROUND: People with HIV (PWH) have an increased risk of peripheral artery disease (PAD), but the pathogenesis is unknown. We aimed to determine the associations between markers of endothelial dysfunction and platelet activation and both PAD at baseline and de novo PAD in PWH. METHODS: In total, 1012 PWH from the longitudinal Copenhagen Comorbidity in HIV-infection (COCOMO) study and 57 age-matched and sex-matched population controls were included. Plasma samples were collected at baseline and analyzed for soluble thrombomodulin, syndecan-1, and CD40 ligand (sCD40L). The ankle-brachial index was measured at baseline and two-year follow-up in PWH. Logistic and Poisson regression models were used to test associations. RESULTS: PWH had higher concentrations of soluble thrombomodulin ( P = 0.03) and syndecan-1 ( P < 0.001) and lower concentration of sCD40L ( P < 0.001) compared with controls. High concentration of soluble thrombomodulin, but not syndecan-1 or sCD40L, was associated with lower odds of PAD in PWH at baseline after adjustments (adjusted odds ratio: 0.50 [0.28, 0.90], P = 0.02). None of the markers were associated with de novo PAD. CONCLUSIONS: PWH had higher concentrations of soluble thrombomodulin and syndecan-1 and lower concentration of sCD40L compared with controls. Soluble thrombomodulin was associated with lower odds of PAD at baseline. Further studies are needed to elucidate the pathogenesis of PAD in people with HIV.

A Pragmatic Randomized Feasibility Trial of Influenza Vaccines.

BACKGROUND: The relative vaccine effectiveness (rVE) of high-dose quadrivalent influenza vaccines (QIV-HD) versus standard-dose quadrivalent influenza vaccines (QIV-SD) against hospitalizations and mortality in the general older population has not been evaluated in an individually randomized trial. Because of the large sample size required, such a trial will need to incorporate innovative, pragmatic elements. METHODS: We conducted a pragmatic, open-label, active-controlled, randomized feasibility trial in Danish citizens aged 65 to 79 years during the 2021­2022 influenza season. Participants were randomly assigned 1:1 to receive QIV-HD or QIV-SD. Randomization was integrated into routine vaccination practice, and the trial relied solely on nationwide administrative health registries for data collection. Outcomes consisted of a feasibility assessment and descriptive rVE estimates. RESULTS: We invited 34,000 persons to participate. A total of 12,477 randomly assigned participants were included in the final analyses. Mean (±SD) age was 71.7±3.9 years, and 5877 (47.1%) were women. Registry-based data collection was feasible, with complete follow-up data for 99.9% of participants. Baseline characteristics were comparable to those of the overall Danish population aged 65 to 79 years. The incidence of hospitalization for influenza or pneumonia was 10 (0.2%) of 6245 in the QIV-HD group and 28 (0.4%) of 6232 in the QIV-SD group (rVE, 64.4%; 95% confidence interval, 24.4 to 84.6). All-cause death occurred in 21 (0.3%) and 41 (0.7%) participants in the QIV-HD and QIV-SD groups, respectively (rVE, 48.9%; 95% confidence interval, 11.5 to 71.3). CONCLUSIONS: Conducting a pragmatic randomized trial of QIV-HD versus QIV-SD using existing infrastructure and registry-based data collection was feasible. The findings of lower incidence of hospitalization for influenza or pneumonia and all-cause mortality in the QIV-HD group compared with the QIV-SD group require replication in a future, fully powered trial.

Exenatide once weekly for alcohol use disorder investigated in a randomized, placebo-controlled clinical trial.

BackgroundAlcohol use disorder (AUD) is a chronic, relapsing brain disorder that accounts for 5% of deaths annually, and there is an urgent need to develop new targets for therapeutic intervention. The glucagon-like peptide-1 (GLP-1) receptor agonist exenatide reduces alcohol consumption in rodents and nonhuman primates, but its efficacy in patients with AUD is unknown.MethodsIn a randomized, double-blinded, placebo-controlled clinical trial, treatment-seeking AUD patients were assigned to receive exenatide (2 mg subcutaneously) or placebo once weekly for 26 weeks, in addition to standard cognitive-behavioral therapy. The primary outcome was reduction in number of heavy drinking days. A subgroup also completed functional MRI (fMRI) and single-photon emission CT (SPECT) brain scans.ResultsA total of 127 patients were enrolled. Our data revealed that although exenatide did not significantly reduce the number of heavy drinking days compared with placebo, it significantly attenuated fMRI alcohol cue reactivity in the ventral striatum and septal area, which are crucial brain areas for drug reward and addiction. In addition, dopamine transporter availability was lower in the exenatide group compared with the placebo group. Exploratory analyses revealed that exenatide significantly reduced heavy drinking days and total alcohol intake in a subgroup of obese patients (BMI > 30 kg/m2). Adverse events were mainly gastrointestinal.ConclusionThis randomized controlled trial on the effects of a GLP-1 receptor agonist in AUD patients provides new important knowledge on the effects of GLP-1 receptor agonists as a novel treatment target in addiction.Trial registrationEudraCT: 2016-003343-11.

Insulin resistance in people living with HIV is associated with exposure to thymidine analogues and/or didanosine and prior immunodeficiency.

BACKGROUND: As people living with HIV (PLWH) are growing older, there is increased incidence of metabolic diseases, including type 2 diabetes mellitus, for which insulin resistance is a key determinant. In this study, we aimed to investigate risk factors associated with insulin resistance in PLWH. METHODS: We included well-treated PLWH without hepatitis co-infection, and with available fasting serum insulin and plasma glucose (n = 643) from the Copenhagen Comorbidity in HIV Infection Study. Insulin resistance was calculated using the homeostasis model assessment of insulin resistance (HOMA-IR). We investigated the association between risk factors and high HOMA-IR in a logistic regression model adjusted for age, sex, abdominal obesity, smoking status, and origin. When including use of thymidine analogues and/or didanosine in the model, we also adjusted for time with HIV. RESULTS: Median (IQR) age of PLWH was 52 years (46-61), and 87% (n = 557) were male. Median (IQR) HOMA-IR was 1.86 (1.23-3.14) mmol/L × mU/L. Risk factors significantly associated with high HOMA-IR included older age, BMI ≥ 25, abdominal obesity, waist circumference, use of thymidine analogues and/or didanosine, time with HIV, and CD4+ nadir < 200 cells/µL. CONCLUSIONS: Insulin resistance in PLWH is associated with both use of thymidine analogues and/or didanosine and prior immunodeficiency suggesting that increased attention on blood glucose in these patients could be beneficial.

High incidence of subclinical peripheral artery disease in people with HIV.

OBJECTIVE: Atherosclerosis is common in people with HIV (PWH). Peripheral artery disease (PAD) is the peripheral manifestation of atherosclerosis, but little is known about the incidence of PAD in PWH. Our objective was to determine the PAD incidence in PWH and to investigate potential risk factors. DESIGN: Prospective longitudinal study on PWH from the Copenhagen Comorbidity in HIV Infection (COCOMO) study cohort. METHODS: We performed ankle-brachial index (ABI) measurements at study entry and at 2-year follow-up and included participants with normal ABI at study entry. We defined de novo PAD as ABI ≤0.9 at follow-up. Using Poisson regression adjusted for age, sex, and smoking, we investigated the role of traditional and HIV-related risk factors, including inflammatory markers. RESULTS: Of 844 PWH followed for a median duration of 2.3 years, 30 (3.6%) developed de novo PAD. All cases were subclinical. Diabetes (relative risk [RR] = 4.90 [95% confidence interval [CI]: 1.99-12.1]), current CD4 + cell count <350 cells/µl (2.66 [1.06-6.71]), longer duration of antiretroviral therapy (antiretroviral therapy [ART], 1.88 [1.06-3.33] per decade), and concentrations of high-sensitivity C-reactive protein (1.33 [1.08-1.63] per doubling) and interleukin-6 (1.38 [1.06-1.80] per doubling), were associated with de novo PAD. CONCLUSIONS: PWH had a high incidence of de novo subclinical PAD. Diabetes, low current CD4 + cell count, duration of ART, and inflammatory markers were associated with de novo PAD, indicating a possible role in PAD pathogenesis in PWH.

Global longitudinal strain predicts atrial fibrillation in individuals without hypertension: A Community-based cohort study.

BACKGROUND: Global longitudinal strain (GLS) is a sensitive marker of myocardial dysfunction and atrial reservoir function. We sought to evaluate its value for predicting atrial fibrillation (AF) in the general population. METHODS: Participants from the Copenhagen City Heart Study examined with echocardiography, including speckle tracking analyses, were included. The endpoint was AF obtained through national registries. Proportional hazards Cox regression was applied, including multivariable adjustments made for CHADS2 and CHARGE-AF risk factors. Abnormal GLS was defined as >-18%. RESULTS: The data from 1,309 participants were analyzed. Of those, 153 (12%) developed AF during a median follow-up time of 15.9 years. The follow-up was 100%. The mean age was 57 years, 38% had hypertension, and GLS was  - 18%. In unadjusted analysis, GLS was a univariable predictor of outcome (1.08 (1.04-1.13), p < 0.001, per 1% absolute decrease), but did not remain an independent predictor after adjusting for neither CHADS2 nor CHARGE-AF risk factors. However, hypertension modified the relationship between GLS and AF (p for interaction = 0.010), such that GLS only predicted AF in subjects without hypertension. In participants without hypertension, GLS remained an independent predictor of AF after adjusting for CHADS2 and CHARGE-AF (HR = 1.11 (1.03-1.20) and HR = 1.09 (1.01-1.19), respectively). In these participants, an abnormal GLS was associated with a more than twofold increased risk of AF (HR = 2.16 (1.26-3.72). The incidence rate was 3.17 and 6.81 per 1000 person-years for normal vs. abnormal GLS, respectively. CONCLUSION: Global longitudinal strain predicts AF in individuals without hypertension from the general population, independently of common risk scores.

The Danish comorbidity in liver transplant recipients study (DACOLT): a non-interventional prospective observational cohort study.

BACKGROUND: Liver transplantation is the only curative treatment for patients with end-stage liver disease. Short-term survival has improved due to improved surgical techniques and greater efficacy of immunosuppressive drugs. However, long-term survival has not improved to the same extent as the short-term survival, and the 10-year survival after liver transplantation is 60%. In addition to liver- and transplant-related causes, comorbidities such as cardiovascular, pulmonary, renal, and metabolic diseases have emerged as leading causes of morbidity and mortality in liver transplant recipients. The objective of this study is to assess the burden of comorbidities and identify both liver- and transplant-related risk factors as well as traditional risk factors that contribute to the pathogenesis of comorbidity in liver transplant recipients. METHODS/DESIGN: The Danish Comorbidity in Liver Transplant Recipients (DACOLT) study is an observational, longitudinal study. We aim to include all adult liver transplant recipients in Denmark (n = approx. 600). Participants will be matched by sex and age to controls from the Copenhagen General Population Study (CGPS) and the Copenhagen City Heart Study (CCHS). Physical and biological measures including blood pressure, ankle-brachial index, spirometry, exhaled nitric oxide, electrocardiogram, transthoracic echocardiography, computed tomography (CT) angiography of the heart, unenhanced CT of chest and abdomen and blood samples will be collected using uniform protocols in participants in DACOLT, CGPS, and CCHS. Blood samples will be collected and stored in a research biobank. Follow-up examinations at regular intervals up to 10 years of follow-up are planned. DISCUSSION: There is no international consensus standard for optimal clinical care or monitoring of liver transplant recipients. This study will determine prevalence, incidence and risk factors for comorbidity in liver transplant recipients and may be used to provide evidence for guidelines on management, treatment and screening and thereby contribute to improvement of the long-term survival. Trial registration ClinicalTrials.gov: NCT04777032; date of registration: March 02, 2021.

Association of Left Ventricular Systolic Function With Incident Heart Failure in Late Life.

Importance: Limited data exist regarding the association of subtle subclinical systolic dysfunction and incident heart failure (HF) in late life. Objective: To assess the independent associations of subclinical impairments in systolic performance with incident HF in late life. Design, Setting, and Participants: This study was a time-to-event analysis of participants without heart failure in the Atherosclerosis Risk in Communities (ARIC) study, a prospective, community-based cohort study, who underwent protocol echocardiography at the fifth study visit (January 1, 2011, to December 31, 2013). Findings were validated independently in participants in the Copenhagen City Heart Study (CCHS). Data analysis was performed from June 1, 2018, to February 28, 2020. Exposures: Left ventricular ejection fraction (LVEF), longitudinal strain (LS), and circumferential strain (CS) measured by 2-dimensional and strain echocardiography. Main Outcomes and Measures: Main outcomes were incident adjudicated HF and HF with preserved and reduced LVEF at a median follow-up of 5.5 years (interquartile range, 5.0-5.8 years). Cox proportional hazards regression models adjusted for demographics, hypertension, diabetes, obesity, smoking, coronary disease, estimated glomerular filtration rate, LV mass index, e', E/e', and left atrial volume index. Lower 10th percentile limits were determined in 374 participants free of cardiovascular disease or risk factors. Results: Among 4960 ARIC participants (mean [SD] age, 75 [5] years; 2933 [59.0%] female; 965 [19%] Black), LVEF was less than 50% in only 76 (1.5%). In the 3552 participants with complete assessment of LVEF, LS, and CS, 983 (27.7%) had 1 or more of the following findings: LVEF less than 60%, LS less than 16.0%, or CS less than 23.7%. Modeled continuously or dichotomized, worse LVEF, LS, and CS were each independently associated with incident HF. The adjusted hazard ratio (HR) per SD decrease in LVEF was 1.41 (95% CI, 1.29-1.55); the HR for LVEF less than 60% was 2.59 (95% CI, 1.99-3.37). Similar findings were observed for continuous LS (HR, 1.37; 95% CI, 1.22-1.53) and dichotomized LS (HR, 1.93; 95% CI, 1.46-2.55) and for continuous CS (HR, 1.39; 95% CI, 1.22-1.57) and dichotomized CS (HR, 2.30; 95% CI, 1.64-3.22). Although the magnitude of risk for incident HF or death associated with impaired LVEF was greater using guideline (HR, 2.99; 95% CI, 2.19-4.09) compared with ARIC-based limits (HR, 1.88; 95% CI, 1.58-2.25), the number of participants classified as impaired was less (104 [2.1%] based on guideline thresholds compared with 692 [13.9%] based on LVEF <60%). The population-attributable risk associated with LVEF less than 60% was 11% compared with 5% using guideline-based limits, a finding replicated in 908 participants in the CCHS. Conclusions and Relevance: These findings suggest that relatively subtle impairments of systolic function (detected based on LVEF or strain) are independently associated with incident HF and HF with reduced LVEF in late life. Current recommended assessments of LV function may substantially underestimate the prevalence of prognostically important impairments in systolic function in this population.

HrHPV testing vs liquid-based cytology in cervical cancer screening among women aged 50 and older: a prospective study.

INTRODUCTION: Evidence supports high-risk human papilloma virus (HPV) testing as the primary cervical cancer screening tool. However, benefits and harms should be carefully considered before replacing liquid-based cytology. In women age 50 and older, we evaluated how a commercially available DNA amplification HPV test compares with routine liquid-based cytology. METHODS: This prospective study included 4043 patients who had a cervical sample analyzed from September 2011 to September 2012. Patients were followed between 64 and 76 months (median: 70 months). Samples were analyzed using both liquid-based cytology and the Cobas 4800 HPV DNA test. We calculated the diagnostic efficacy of liquid-based cytology and HPV, with or without the opposite test as triage, using cervical intraepithelial neoplasia (CIN2+/CIN3+) as reference. RESULTS: The patients had a median age of 58 years, (range; 50-90). At baseline, HPV prevalence was 8.0%: a total of 3.7% of patients had atypical squamous cells of undetermined significance or worse (ASCUS+). Positive test results were 1.9% for liquid-based cytology with HPV triage and 3.0% for HPV with liquid-based cytology triage. The cumulative incidence of CIN3+ was 1.0% (40/4043). Sensitivities for CIN3+ were: liquid-based cytology 47.5% (31.5%-63.9%); liquid-based cytology with HPV triage 45.0% (29.3%-61.5%); HPV 90.0% (76.3%-97.2%); and HPV with liquid-based cytology triage 67.5% (50.9%-81.4%). Corresponding specificities were: liquid-based cytology 96.6% (96.0%-97.2%); liquid-based cytology with HPV triage 98.5% (98.0%-98.8%); HPV 92.8% (92.0%-93.6%); and HPV with liquid-based cytology triage 97.7% (97.2%-98.1%). At baseline, HPV testing overlooked five cases of gynecological cancer other than cervical cancer. Five cervical cancers were detected, two had been overlooked at baseline by liquid-based cytology and two by HPV testing CONCLUSION: HPV screening using DNA amplification is a promising alternative to liquid-based cytology in women age 50 and older, but evaluation of alternative triage methods is warranted. The risk of overlooking cancers needs consideration when replacing liquid-based cytology with HPV testing as a method for primary screening.

Low High-Density Lipoprotein Cholesterol to Monitor Long-Term Average Increased Triglycerides.

CONTEXT: Increased triglyceride-rich remnants represent a causal risk factor for ischemic cardiovascular disease. OBJECTIVE: We tested the hypothesis that low high-density lipoprotein (HDL) cholesterol can be used to monitor long-term high triglycerides/remnant cholesterol, just as high hemoglobin A1c (HbA1c) can be used to monitor long-term high glucose levels. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTIONS: We studied cross-sectionally 108 731 individuals, dynamically 1313 individuals with lipid measurement at 10 repeated visits, short-term 305 individuals during a fat load, and long-term 10 479 individuals with 2 lipid measurements 10 years apart. MAIN OUTCOME MEASURES: Levels of HDL cholesterol and triglycerides. RESULTS: Cross-sectionally, HDL cholesterol was inversely associated with triglycerides (R2 = 0.26) and remnant cholesterol (R2 = 0.26). Dynamically, major changes in triglyceride levels from measurement to measurement were mimicked by corresponding modest changes in HDL cholesterol. In the short-term after a fat load, median triglycerides increased 96% while HDL cholesterol decreased only 1%. Long-term, in individuals with measurements 10 years apart, those who initially had the highest triglycerides and corresponding lowest HDL cholesterol, still had highest triglycerides and lowest HDL cholesterol 10 years later. Prospectively, individuals with increased triglycerides/remnant cholesterol had increased risk of myocardial infarction; however, when the HDL cholesterol monitoring was removed, increased triglycerides/remnant cholesterol were largely no longer associated with increased risk of myocardial infarction. CONCLUSIONS: Low HDL cholesterol is a stable marker of average high triglycerides/remnant cholesterol. This suggests that low HDL cholesterol can be used to monitor long-term average high triglycerides and remnant cholesterol, analogous to high HbA1c as a long-term monitor of average high glucose levels.

Otoacoustic Emissions for Outcome Prediction in Postanoxic Brain Injury.

Background: Non-invasive, easy-to-use bedside tools to estimate prognosis in unresponsive patients with postanoxic brain injury are needed. We assessed the usefulness of otoacoustic emissions as outcome markers after cardiac arrest. Methods: Distortion product otoacoustic emissions (DPOAE) and transient evoked otoacoustic emissions (TEOAE) were measured in cardiac arrest patients whose prognosis was deemed to be poor following standard neurological assessment (n = 10). Ten patients with myocardial infarction without prior loss of consciousness served as controls. Results: Compared to controls with myocardial infarction, cardiac arrest patients with poor neurological prognosis had significantly less often preserved DPOAE (9.2 vs. 40.8% positive measurements; OR 0.15 (CI 0.07-0.30); p < 0.0001). Partially preserved DPOAE were noted in 4 cardiac arrest patients. TEOAE were not statistically different between the two groups. Conclusions: Despite their convenience, otoacoustic emissions cannot be used as reliable prognostic markers in cardiac arrest survivors. This is because we identified 4 cases with partially preserved otoacoustic emissions in a sample of 10 unresponsive post-cardiac arrest patients whose neurological condition was so poor that active treatment was withdrawn. However, we suggest that future research should address if decaying outer hair cell function over time may serve as a proxy for evolving ischemic brain damage.

A multicenter study on objective and subjective benefits with a transcutaneous bone-anchored hearing aid device: first Nordic results.

Examination of objective as well as subjective outcomes with a new transcutaneous bone-anchored hearing aid device. The study was designed as a prospective multicenter consecutive case-series study involving tertiary referral centers at two Danish University Hospitals. A total of 23 patients were implanted. Three were lost to follow-up. Patients had single-sided deafness, conductive or mixed hearing loss. INTERVENTION: Rehabilitative. Aided and unaided sound field hearing was evaluated objectively using (1) pure warble tone thresholds, (2) pure-tone average (PTA4), (3) speech discrimination score (SDS) in quiet, and (4) speech reception threshold 50% at 70 dB SPL noise level (SRT50%). Subjective benefit was evaluated by three validated questionnaires: (1) the IOI-HA, (2) the SSQ-12, and (3) a questionnaire evaluating both the frequency and the duration of hearing aid usage. The mean aided PTA4 was lowered by 14.7 dB. SDS was increased by 37.5% at 50 dB SPL, SRT50% in noise improved 1.4 dB. Aided thresholds improved insignificantly at frequencies above 2 kHz. 52.9% of the patients used their device every day, and 76.5% used the device at least 5 days a week. Mean IOI-HA score was 3.4, corresponding to a good benefit. In SSQ-12, "quality of hearing" scored especially high. Patients with a conductive and/or mixed hearing loss benefitted the most. This device demonstrates a significant subjective hearing benefit 8 month post surgery. In patients with conductive and/or mixed hearing losses, patient satisfaction and frequency of use were high. Objective gain measures showed less promising results especially in patients with single-sided deafness (SSD) compared to other bone conduction devices.
