RESUMEN

Veterans living with HIV (VLWH) and hepatitis C virus (HCV) co-infection have an exacerbated risk of cardiovascular disease (CVD). It is unknown if HCV cure reduces CVD risk in this population. We evaluated changes in low-density lipoprotein (LDL), as a surrogate of CVD risk, 18 months after HCV cure in VLWH. We found significant increases in LDL in VLWH with advanced fibrosis, potentially increasing CVD risk. Lower LDL thresholds to initiate lipid-lowering therapies in VLWH after HCV cure may be warranted.

RESUMEN

The demands and costs of health care resulting from increasingly ageing populations have become a major public health issue in the United Kingdom and other industrially developed nations. Concern with cost containment and shortage of resources has prompted a progressive shift in responsibility from state provision of care to individual patients and their families, and from the institutional setting of the hospital to the domestic home. Under the guise of choice and patient centredness, end-of-life care is framed within a discourse of the 'good death': free from distress and discomfort and accompanied by significant others in the preferred place, usually assumed to be home. The promotion of the 'good death' as a technical accomplishment enabled by pre-emptive discussion and advance care planning has sidelined recognition of the nature and significance of the pain and suffering involved in the experience of dying. There has been little research into the disparity between policy and professional assumptions and the lived reality of end of life. In this paper, we present findings from a qualitative study of how terminally ill patients, bereaved family members, and members of the public understand, anticipate, and experience death and dying. These findings contribute to an important and timely critique of the normative idealisation of death and dying in health policy and practice, and the need to attend closely to the real-world experiences of patients and the public as a prerequisite for identifying and remedying widespread shortcomings in end-of-life care.

RESUMEN

BACKGROUND: The mRNA-1345 vaccine demonstrated efficacy against RSV disease with acceptable safety in adults ≥60 years in the ConquerRSV trial. Here, humoral immunogenicity results from the trial are presented. METHODS: This phase 2/3 trial randomly assigned adults (≥60 years) to mRNA-1345 50-µg encoding prefusion F (preF) glycoprotein (n = 17,793) vaccine or placebo (n = 17,748). RSV-A and RSV-B neutralizing antibody (nAb) and preF binding antibody (bAb) levels at baseline and day 29 post-vaccination were assessed in a per-protocol immunogenicity subset ([PPIS]; mRNA-1345, n = 1515; placebo, n = 333). RESULTS: Day 29 nAb geometric mean titers (GMTs) increased 8.4-fold against RSV-A and 5.1-fold against RSV-B from baseline. Seroresponses (4-fold rise from baseline) in the mRNA-1345 groups were 74.2% and 56.5% for RSV-A and RSV-B, respectively. Baseline GMTs were lower among participants who met the seroresponse criteria than those who did not. mRNA-1345 induced preF bAbs at day 29, with a pattern similar to nAbs. Day 29 antibody responses across demographic and risk subgroups were generally consistent with the overall PPIS. CONCLUSION: mRNA-1345 enhanced RSV-A and RSV-B nAbs and preF bAbs in adults (≥60 years) across various subgroups, including those at risk for severe disease, consistent with its demonstrated efficacy in the prevention of RSV disease.

RESUMEN

BACKGROUND: Motor Neurone Disease (MND) leads to muscle weakening, affecting movement, speech, and breathing. Home mechanical ventilation, particularly non-invasive ventilation (NIV), is used to alleviate symptoms and support breathing in people living with MND. While home mechanical ventilation can alleviate symptoms and improve survival, it does not slow the progression of MND. This study addresses gaps in understanding end-of-life decision-making in those dependent on home mechanical ventilation, considering the perspectives of patients, family members, and bereaved families. METHODS: A UK-wide qualitative study using flexible interviews to explore the experiences of people living with MND (n = 16), their family members (n = 10), and bereaved family members (n = 36) about the use of home mechanical ventilation at the end of life. RESULTS: Some participants expressed a reluctance to discuss end-of-life decisions, often framed as a desire to "live for the day" due to the considerable uncertainty faced by those with MND. Participants who avoided end-of-life discussions often engaged in 'selective decision-making' related to personal planning, involving practical and emotional preparations. Many faced challenges in hypothesising about future decisions given the unpredictability of the disease, opting to make 'timely decisions' as and when needed. For those who became dependent on ventilation and did not want to discuss end of life, decisions were often 'defaulted' to others, especially once capacity was lost. 'Proactive decisions', including advance care planning and withdrawal of treatment, were found to empower some patients, providing a sense of control over the timing of their death. A significant proportion lacked a clear understanding of the dying process and available options. CONCLUSIONS: The study highlights the complexity and evolution of decision-making, often influenced by the dynamic and uncertain nature of MND. The study emphasises the need for a nuanced understanding of decision-making in the context of MND.

RESUMEN

BACKGROUND: An mRNA-based RSV vaccine, mRNA-1345, is under clinical investigation to address RSV disease burden in older adults. METHODS: This phase 1, randomized, observer-blind, placebo-controlled, dose-ranging study evaluated safety, reactogenicity, and immunogenicity of mRNA-1345 in adults 65-79 years (NCT04528719). Participants were randomized to receive 1-dose of mRNA-1345 (12.5, 25, 50, 100, or 200-µg) or placebo and matched mRNA-1345 booster or placebo at 12-months. RESULTS: Overall, 298 participants received the first injection; 247 received the 12-month booster injection. mRNA-1345 was generally well-tolerated after both injections, with the most frequently reported solicited adverse reactions being injection-site pain, fatigue, headache, arthralgia, and myalgia. Reactogenicity was higher after the booster injection than the first injection but similar severity, time-to-onset, and duration. A single mRNA-1345 injection boosted RSV-A and RSV-B neutralizing antibody titers (nAb) and prefusion-F-binding antibody (preF-bAb) concentrations at 1-month (geometric mean-fold rises: RSV-A, 10.2-16.5; RSV-B, 5.3-12.5; preF-bAb, 7.2-12.1). RSV antibody levels remained above baseline through 12-months, indicating immune persistence. A 12-month booster injection also increased RSV-A and RSV-B nAb titers and preF-bAb concentrations; titers post-booster injection were numerically lower compared to titers after the first-dose, with overlapping 95% CIs. CONCLUSIONS: mRNA-1345 was well-tolerated and immunogenic following a single injection and a 12-month booster. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04528719.

RESUMEN

Talking about death and dying is promoted in UK health policy and practice, from a perception that to do so encourages people to plan for their end of life and so increase their likelihood of experiencing a good death. This encouragement occurs alongside a belief that members of the public are reluctant to talk about death, although surveys suggest this is not the case. This paper describes findings from a research study in which people participated in deliberative discussion groups during which they talked about a range of topics related to death, including talking about death, the good death, choice and planning and compassionate communities. Here we report what they had to say in relation to talking about death and dying. We identified three themes: 1. The difference between talking about death as an abstract concept and confronting the certainty of death, 2. how death and dying presents issues for planning and responsibility, and 3. approaches to normalising death within society. For our participants, planning was considered most appropriate in relation to wills and funerals, while dying was considered too unpredictable to be easy to plan for; they had complex ideas about the value of talking about death and dying.

RESUMEN

Overall, fewer Veterans were eligible for PrEP in 2020, compared to 2019, and 2018 (Maryland Veterans Affairs Health Care System- MVAHCS-: n = 890 (2020), n = 1533 (2019); Washington DC Veterans Affairs Medical Center -DC VAMC- n = 1119 (2020), n = 1716 (2019)). While the proportion of Veterans engaged in PrEP out of those eligible for PrEP increased in 2020 compared to 2019 at both sites (MVAHCS: 5.73% (2020) vs. 3.39% (2019) p-value = 0.006; F = 7.58, and DC VAMC: 15.91% (2020) vs. 9.38% (2019) p-value < 0.001; F = 27.64), the absolute number of Veterans engaged in PrEP remained unchanged (MVAHCS n = 51 (2020) and n = 52 (2019); DC VAMC n = 178 (2020) and n = 161 (2019)). Engagement in PrEP was significantly lower among Black Veterans compared to White Veterans at the DC VAMC across all FY with a widening gap in 2020. Cisgender women were less likely to be engaged in PrEP compared to cisgender men at both sites and throughout all FY with a wider gender gap in 2020. There were no significant differences in retention in PrEP between FY.Anticipated improvements in linkage, engagement, and retention in PrEP in 2020 at the MVAHCS and DC VAMC may not have been seen due to the COVID-19 pandemic. Furthermore, engagement rates in PrEP remained low overall, particularly among Black Veterans and cisgender women. Novel PrEP delivery models are needed to engage these populations in PrEP following the COVID-19 pandemic. Interactive dashboards and tele-PrEP may have played a big role in sustained retention in PrEP at the VHA.

RESUMEN

Home has become established as the preferred place of death within health policy and practice in the UK and internationally. However, growing awareness of the structured inequalities underpinning end-of-life care and the challenges for family members undertaking care at home raise questions about the nature of patient and public preferences and priorities regarding place of death and the feasibility of home management of the complex care needs at the end-of-life. This paper presents findings from a qualitative study of 12 patients' and 34 bereaved family caregivers' perspectives and priorities regarding place of death. Participants expressed complex and nuanced accounts in which place of death was not afforded an overarching priority. The study findings point to public pragmatism and flexibility in relation to place of death, and the misalignment of current policy with public priorities that are predominantly for comfort and companionship at the end-of-life, regardless of place.

RESUMEN

BACKGROUND: Respiratory syncytial virus (RSV) can cause substantial morbidity and mortality among older adults. An mRNA-based RSV vaccine, mRNA-1345, encoding the stabilized RSV prefusion F glycoprotein, is under clinical investigation. METHODS: In this ongoing, randomized, double-blind, placebo-controlled, phase 2-3 trial, we randomly assigned, in a 1:1 ratio, adults 60 years of age or older to receive one dose of mRNA-1345 (50 µg) or placebo. The two primary efficacy end points were the prevention of RSV-associated lower respiratory tract disease with at least two signs or symptoms and with at least three signs or symptoms. A key secondary efficacy end point was the prevention of RSV-associated acute respiratory disease. Safety was also assessed. RESULTS: Overall, 35,541 participants were assigned to receive the mRNA-1345 vaccine (17,793 participants) or placebo (17,748). The median follow-up was 112 days (range, 1 to 379). The primary analyses were conducted when at least 50% of the anticipated cases of RSV-associated lower respiratory tract disease had occurred. Vaccine efficacy was 83.7% (95.88% confidence interval [CI], 66.0 to 92.2) against RSV-associated lower respiratory tract disease with at least two signs or symptoms and 82.4% (96.36% CI, 34.8 to 95.3) against the disease with at least three signs or symptoms. Vaccine efficacy was 68.4% (95% CI, 50.9 to 79.7) against RSV-associated acute respiratory disease. Protection was observed against both RSV subtypes (A and B) and was generally consistent across subgroups defined according to age and coexisting conditions. Participants in the mRNA-1345 group had a higher incidence than those in the placebo group of solicited local adverse reactions (58.7% vs. 16.2%) and of systemic adverse reactions (47.7% vs. 32.9%); most reactions were mild to moderate in severity and were transient. Serious adverse events occurred in 2.8% of the participants in each trial group. CONCLUSIONS: A single dose of the mRNA-1345 vaccine resulted in no evident safety concerns and led to a lower incidence of RSV-associated lower respiratory tract disease and of RSV-associated acute respiratory disease than placebo among adults 60 years of age or older.

RESUMEN

BACKGROUND: Current estimates of the economic burden of respiratory syncytial virus (RSV) are needed for policymakers to evaluate adult RSV vaccination strategies. METHODS: A cost-of-illness model was developed to estimate the annual societal burden of RSV in US adults aged ≥60 years. Additional analyses were conducted to estimate the burden of hospitalized RSV in all adults aged 50-59 years and in adults aged 18-49 years with potential RSV risk factors. RESULTS: Among US adults aged ≥60 years, the model estimated 4.0 million annual RSV cases (95% UI, 2.7-5.6 million) and an annual economic burden of $6.6 billion (95% UI, $3.1-$12.9 billion; direct medical costs, $2.9 billion; indirect costs, $3.7 billion). The 4% of RSV cases that were hospitalized contributed to 94% of direct medical costs. Additional analyses estimated $422 million in annual hospitalization costs among all adults aged 50-59 years. Among adults aged 18-49 years with RSV risk factors, annual per capita burden was highest among people with congestive heart failure at $51,100 per 1000 people. DISCUSSION: The economic burden of RSV is substantial among adults aged ≥50 years, and among adults aged 18-49 years with RSV risk factors, underscoring the need for preventive interventions for these populations.

RESUMEN

Objectives: Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 infection is associated with lower plasma glutathione (GSH) levels due to oxidative stress. However, plasma levels may not reflect brain GSH levels. Individuals with post-acute sequelae of COVID-19 (PASC) have a higher prevalence of cognitive fatigue, which might be related to altered brain γ-aminobutyric-acid (GABA) levels. Hence, our study aims to measure the brain GSH and GABA levels in PASC. Methods: 29 PASC participants and 24 uninfected controls were recruited for this study. Each was evaluated with detailed neuropsychiatric assessments and an edited proton MRS (Hadamard Encoding and Reconstruction of Mega-Edited Spectroscopy, HERMES) method to measure GABA and GSH concentrations in predominantly grey matter (GM) and predominantly white matter (WM) brain frontal voxels. Results: PASC participants were 219 ± 137 days since their COVID-19 diagnosis. Nine individuals with PASC were hospitalized. Compared to controls, individuals with PASC had similar levels of GABA in both brain regions, but lower GSH and greater age-related GSH decline in the frontal GM region. Conclusions: The lower-than-normal frontal GM GSH level in participants with PASC suggest that they have ongoing oxidative stress in the brain, and that older individuals may be even more vulnerable to oxidative stress.

RESUMEN

Objective: To quantify neuropsychiatric symptoms reported by individuals with Post-Acute Sequelae of COVID-19 (PASC) using the NIH Toolbox® for Assessment of Neurological and Behavioral Function (NIHTB) and Patient-Reported Outcomes Measurement Information System (PROMIS). Methods: 30 PASC (20 women, 21-63 years) and 27 control (16 women, 25-68 years) participants completed three NIHTB batteries and selected PROMIS tests. Group differences on fully corrected T-scores were evaluated using analysis of covariance and Cohen's d effect sizes. A linear regression model predicted the effects from time since diagnosis. Results: PASC had poorer emotional health and motor function than controls, including poorer locomotion, endurance and dexterity, but normal cognitive function, ~7 months post-infection, compared to controls. PASC participants had a steeper age-related decline on 2-Minute Walk than controls. T-scores on four cognitive and three motor tests improved with longer time since diagnosis. Conclusion: NIHTB and PROMIS captured the poorer emotional health and motor function in PASC, including the novel findings of deficits locomotion and dexterity. The normal cognitive performance suggests subclinical effects that may be compensated by neural and cognitive reserves, and manifested subjectively by the negative psychological effects and fatigue. The persistent emotional and psychiatric symptoms necessitate mental health treatment be prioritized.

RESUMEN

BACKGROUND: Residual inflammation in people with HIV (PWH) despite suppression of HIV replication is associated with many comorbidities including cardiovascular disease. Targeting inflammation may decrease the risk of cardiovascular disease. METHODS: An open label randomized study was conducted to evaluate the effect of nine months of 81 mg aspirin versus 40 mg atorvastatin in antiretroviral therapy (ART) treated PWH and elite controllers (EC), not on ART. Biomarkers associated with inflammation and virologic indices were measured and analyzed using nonparametric and linear mixed effect models. RESULTS: Fifty-three participants were randomized and 44 were included in the final analysis. Median age was 54 years, 72% were male, 59% were Black. Median CD4 + count was 595 cells/µl in the aspirin and 717 cells/µl in the atorvastatin arm. After 9 months of treatment, plasma soluble (s) CD14 + was reduced in the aspirin group within both treated PWH and EC ( P  = 0.0229), yet only within treated PWH in the atorvastatin group ( P  = 0.0128). A 2.3% reduction from baseline in tissue factor levels was also observed in the aspirin arm, driven by the EC group. In the atorvastatin arm, there was a 4.3% reduction in interleukin-8 levels ( P  = 0.02) and a small decrease of activated CD4 + T cells ( P  < 0.001). No statistically significant differences were observed in the plasma HIV viral load and cell-associated (CA) HIV DNA and RNA. CONCLUSIONS: Aspirin and atorvastatin could play a role in targeting HIV-associated inflammation. Elite controllers may warrant special consideration for anti-inflammatory strategies.

RESUMEN

Globally, ∼56.8 million people are chronically infected with hepatitis C virus (HCV), with about half residing in Asia. The cost and efficiency of delivering regimens based on direct-acting antiviral agents for HCV are important considerations in implementing these curative treatments. For sofosbuvir-based regimens, most patients are treated for 12 weeks; however, treatment for 8 weeks has been shown to cure HCV infection in 95% of patients without cirrhosis. Furthermore, virological failure after 8-week treatment occurs in only 1%-2% of individuals without cirrhosis, who have a favorable IFNL4 genotype, which is present in >50% of South Asians and >80% of East Asians. We propose that sofosbuvir-based treatment for 8 weeks, or perhaps shorter, would yield high response rate regimens in Asian countries and markedly increase the number of patients who could be cured for a given cost of the medication. We propose that a noninferiority trial in an East Asian population be conducted to test this hypothesis.

RESUMEN

BACKGROUND AND OBJECTIVES: Post-COVID condition (PCC) is common and often involves neuropsychiatric symptoms. This study aimed to use blood oxygenation level-dependent fMRI (BOLD-fMRI) to assess whether participants with PCC had abnormal brain activation during working memory (WM) and whether the abnormal brain activation could predict cognitive performance, motor function, or psychiatric symptoms. METHODS: The participants with PCC had documented coronavirus disease 2019 (COVID-19) at least 6 weeks before enrollment. Healthy control participants had no prior history of COVID-19 and negative tests for severe acute respiratory syndrome coronavirus 2. Participants were assessed using 3 NIH Toolbox (NIHTB) batteries for Cognition (NIHTB-CB), Emotion (NIHTB-EB), and Motor function (NIHTB-MB) and selected tests from the Patient-Reported Outcomes Measurement Information System (PROMIS). Each had BOLD-fMRI at 3T, during WM (N-back) tasks with increasing attentional/WM load. RESULTS: One hundred sixty-nine participants were screened; 50 fulfilled the study criteria and had complete and usable data sets for this cross-sectional cohort study. Twenty-nine participants with PCC were diagnosed with COVID-19 242 ± 156 days earlier; they had similar ages (42 ± 12 vs 41 ± 12 years), gender proportion (65% vs 57%), racial/ethnic distribution, handedness, education, and socioeconomic status, as the 21 uninfected healthy controls. Despite the high prevalence of memory (79%) and concentration (93%) complaints, the PCC group had similar performance on the NIHTB-CB as the controls. However, participants with PCC had greater brain activation than the controls across the network (false discovery rate-corrected p = 0.003, Tmax = 4.17), with greater activation in the right superior frontal gyrus (p = 0.009, Cohen d = 0.81, 95% CI 0.15-1.46) but lesser deactivation in the default mode regions (p = 0.001, d = 1.03, 95% CI 0.61-1.99). Compared with controls, participants with PCC also had poorer dexterity and endurance on the NIHTB-MB, higher T scores for negative affect and perceived stress, but lower T scores for psychological well-being on the NIHTB-EB, as well as more pain symptoms and poorer mental and physical health on measures from the PROMIS. Greater brain activation predicted poorer scores on measures that were abnormal on the NIHTB-EB. DISCUSSION: Participants with PCC and neuropsychiatric symptoms demonstrated compensatory neural processes with greater usage of alternate brain regions, and reorganized networks, to maintain normal performance during WM tasks. BOLD-fMRI was sensitive for detecting brain abnormalities that correlated with various quantitative neuropsychiatric symptoms.

RESUMEN

Objectives: We aimed to compare brain white matter integrity in participants with post-COVID-19 conditions (PCC) and healthy controls. Methods: We compared cognitive performance (NIH Toolbox®), psychiatric symptoms and diffusion tensor imaging (DTI) metrics between 23 PCC participants and 24 controls. Fractional anisotropy (FA), axial (AD), radial (RD), and mean (MD) diffusivities were measured in 9 white matter tracts and 6 subcortical regions using MRICloud. Results: Compared to controls, PCC had similar cognitive performance, but greater psychiatric symptoms and perceived stress, as well as higher FA and lower diffusivities in multiple white matter tracts (ANCOVA-p-values≤0.001-0.048). Amongst women, PCC had higher left amygdala-MD than controls (sex-by-PCC p=0.006). Regardless of COVID-19 history, higher sagittal strata-FA predicted greater fatigue (r=0.48-0.52, p<0.001) in all participants, and higher left amygdala-MD predicted greater fatigue (r=0.61, p<0.001) and anxiety (r=0.69, p<0.001) in women, and higher perceived stress (r=0.45, p=0.002) for all participants. Conclusions: Microstructural abnormalities are evident in PCC participants averaged six months after COVID-19. The restricted diffusivity (with reduced MD) and higher FA suggest enhanced myelination or increased magnetic susceptibility from iron deposition, as seen in stress conditions. The higher amygdala-MD in female PCC suggests persistent neuroinflammation, which might contribute to their fatigue, anxiety, and perceived stress.

RESUMEN

INTRODUCTION: Home mechanical ventilation can be used to manage symptoms of breathlessness and sustain life for people living with motor neuron disease (plwMND). In the UK, less than 1% of plwMND use tracheostomy ventilation (TV). This contrasts with some other countries, where rates are much higher. Due to a lack of evidence about its feasibility, cost-effectiveness or outcomes, TV is not covered in the UK National Institute for Health and Care Excellence guidance. Most plwMND receiving TV in the UK do so as an unplanned crisis intervention, which can lead to a prolonged hospital stay while a complex care package is arranged. There is insufficient literature addressing the burdens and benefits of TV, how it should be initiated and delivered, and how future care choices for plwMND can be supported. The aim of this research is to provide new understandings of the experiences of plwMND using TV, and those of family members and healthcare professionals (HCPs) involved in their care. METHODS AND ANALYSIS: A UK-wide qualitative study with two workstreams: (1) Patient focused case studies (n=6) including plwMND, family members and HCPs to focus on experiences and tasks of daily living from multiple perspectives. (2) Interviews with plwMND (n=10), family members, including bereaved family members (n=10) and HCPs (n=20) on broader experiences and issues relating to use of TV, such as ethical considerations and decision making.

RESUMEN

OBJECTIVES: To narrate the canon of knowledge around symptom control at end of life for patients using, or having recently used, non-invasive advanced respiratory support (NARS) at end of life for respiratory failure. METHODS: A systematic review forming a narrative synthesis from a wide range of sample papers from Medline, Embase, CINAHL, Emcare, Cochrane and OpenGrey databases. A secondary search of grey literature was also performed with hand searching reference lists and author citations. The review was undertaken using the ENTREQ checklist for quality. RESULTS: In total, 22 studies were included in the synthesis and four themes were generated: NARS as a buoy (NARS can represent hope and relief from the symptoms of respiratory failure), NARS as an anchor (NARS brings significant treatment burden), Impact on Staff (uncertainty over the balance of benefit and burden as well as complex patient care drives distress among staff providing care) and the Process of Withdrawal (withdrawal of therapy felt to be futile exists as discrete event in patient care but is otherwise poorly defined). CONCLUSION: NARS represents a complex interplay of hope, symptom control, unnaturally prolonged death and treatment burden. The literature captures the breadth of these issues, but further, detailed, research is required in almost every aspect of practice around end-of-life care and NARS-especially how to manage symptoms at the end of life.

RESUMEN

OBJECTIVES: The purpose of this study was to identify the patient, injury, and treatment factors associated with infection of bicondylar plateau fractures and to evaluate whether center variation exists. DESIGN: Retrospective review. SETTING: Eighteen academic trauma centers. PATIENTS/PARTICIPANTS: A total of 1,287 patients with 1,297 OTA type 41-C bicondylar tibia plateau fractures who underwent open reduction and internal fixation were included. Exclusion criteria were follow-up less than 120 days, insufficient documentation, and definitive treatment only with external fixation. INTERVENTION: Open reduction and internal fixation. MAIN OUTCOME MEASUREMENTS: Superficial and deep infection. RESULTS: One hundred one patients (7.8%) developed an infection. In multivariate regression analysis, diabetes (DM) (OR [odds ratio] 3.24; P ≤ 0.001), alcohol abuse (EtOH) (OR 1.8; P = 0.040), dual plating (OR 1.8; P ≤ 0.001), and temporary external fixation (OR 2.07; P = 0.013) were associated with infection. In a risk-adjusted model, we found center variation in infection rates (P = 0.030). DISCUSSION: In a large series of patients undergoing open reduction and internal fixation of bicondylar plateau fractures, the infection rate was 7.8%. Infection was associated with DM, EtOH, combined dual plating, and temporary external fixation. Center expertise may also play a role because one center had a statistically lower rate and two trended toward higher rates after adjusting for confounders. LEVEL OF EVIDENCE: Level IV-Therapeutic retrospective cohort study.
