Abstract
Background: Women living with HIV (WLWH) are often coinfected with Trichomonas vaginalis (TV), and annual screening is recommended. Our goal was to assess differences in TV prevalence at study entry and over time in enrollment cohorts of the Women's Interagency HIV Study. Methods: In a multisite study, TV was diagnosed by wet mount microscopy. Prevalence was determined across four enrollment waves: 1994-1995, 2001-2002, 2011-2012, and 2013-2015. Generalized estimating equation multivariable logistic regression models assessed changes in visit prevalence across waves after controlling for HIV disease severity and other risks. Results: At 63,824 person-visits (3,508 WLWH and 1,262 women without HIV), TV was diagnosed by wet mount at 1979 visits (3.1%). After multivariable adjustment, HIV status was not associated with TV detection, which was more common among younger women, women with multiple partners, and irregular condom use. All enrollment waves showed a decline in TV detection over time, although p-value for trend did not reach significance for most recent waves. To explore the potential utility of screening among WLWH, we assessed rates of TV detection among women without appreciable vaginal discharge on examination. Initial TV prevalence among asymptomatic women was 3.5%, and prevalence decreased to 0.5%-1% in the most recent wave (2013-2015) (p-trend <0.0001). Conclusions: In this cohort, TV rates are low among WLWH, and HIV does not increase TV risk. Screening may benefit newly diagnosed WLWH, women with risk factors, or those receiving care sporadically but is unlikely to further reduce the low rate of TV among women in care, especially older women without multiple partners. The clinical trials registration number for WIHS is NCT00000797.

Abstract
PURPOSE The optimal duration of post-radiation temozolomide in newly diagnosed glioblastoma remains unclear, with no published phase III randomised trials. Standard-of-care stipulates 6 months. However, in routine care, it is often extended to 12 months, despite lacking robust supporting data. METHODS GEINO14-01 (Spain) and EX-TEM (Australia) studies enrolled glioblastoma patients without progression at the end of 6 months post-radiation temozolomide. Participants were randomised 1:1 to six additional months of temozolomide or observation. Primary endpoint was 6-month progression free survival from date of randomisation (6mPFS). Secondary endpoints included overall survival (OS) and toxicity. 204 patients were required to detect an improvement in 6mPFS from 50 to 60% (80% power). Neither study recruited sufficient patients. We performed a combined analysis of individual patient data. RESULTS 205 patients were recruited: 159 in GEINO14-01 (2014-2018) and 46 in EX-TEM (2019-2022). Median follow-up was 20.0 and 14.5 months. Baseline characteristics were balanced. There was no significant improvement in 6mPFS (57.2% vs 64.0%, OR0.75, p = 0.4), nor across any subgroups, including MGMT methylated; PFS (HR0.92, p = 0.59, median 7.8 vs 9.7 months); or OS (HR1.03, p = 0.87, median 20.1 vs 19.4 months). During treatment extension, 64% experienced any grade adverse event, mainly fatigue and gastrointestinal (both 54%). Only a minority required treatment changes: 4.5% dose delay, 7.5% dose reduction, 1.5% temozolomide discontinuation. CONCLUSION For glioblastoma patients, extending post-radiation temozolomide from 6 to 12 months is well tolerated but does not improve 6mPFS. We could not identify any subset that benefitted from extended treatment. Six months should remain standard-of-care.

Abstract
PURPOSE The objective of this work was to demonstrate that clinical OAT1-mediated DDIs can be predicted using physiologically based pharmacokinetic (PBPK) modeling. METHODS LY404039 is a metabotropic glutamate receptor 2/3 agonist and the active moiety of the prodrug pomaglumetad methionil (LY2140023). After oral administration, pomaglumetad methionil is rapidly taken up by enterocytes via PEPT1 and once absorbed, converted to LY404039 via membrane dehydropeptidase 1 (DPEP1). LY404039 is renally excreted by both glomerular filtration and active secretion and in vitro studies showed that the active secretion of LY404039 was mediated by the organic anion transporter 1 (OAT1). Both clinical and in vitro data were used to build a PBPK model to predict OAT1-mediated DDIs. RESULTS In vitro inhibitory potencies (IC50) of the known OAT inhibitors, probenecid and ibuprofen, were determined to be 4.00 and 2.63 µM, respectively. Subsequently, clinical drug-drug interaction (DDI) study showed probenecid reduced the renal clearance of LY404039 by 30 to 40%. The PBPK bottom-up model, predicted a renal clearance that was approximately 20% lower than the observed one. The middle-out model, using an OAT1 relative activity factor (RAF) of 3, accurately reproduced the renal clearance of LY404039 and pharmacokinetic (PK) changes of LY404039 in the presence of probenecid. CONCLUSIONS OAT1- mediated DDIs can be predicted using in vitro measured IC50 and PBPK modeling. The effect of ibuprofen was predicted to be minimal (AUC ratio of 1.15) and not clinically relevant.

Abstract
BACKGROUND A trial found that a community health worker (CHW) strategy using "Health Scouts" improved HIV care uptake and ART coverage. To better understand outcomes and areas for improvement, we conducted an implementation science evaluation. METHODS Using the RE-AIM framework, quantitative methods included analyses of a community-wide survey (n = 1903), CHW log books, and phone application data. Qualitative methods included in-depth interviews (n = 72) with CHWs, clients, staff, and community leaders. RESULTS Thirteen Health Scouts logged 11,221 counseling sessions; 2532 unique clients were counseled. 95.7% (1789 of 1891) of residents reported awareness of the Health Scouts. Overall, reach (self-reported receipt of counseling) was 30.7% (580 of 1891). Unreached residents were more likely to be male and HIV seronegative ( P < 0.05). Qualitative themes included the following: (1) reach was promoted by perceived usefulness but deterred by busy client lifestyles and stigma, (2) effectiveness was enabled through good acceptability and consistency with the conceptual framework, (3) adoption was facilitated by positive impacts on HIV service engagement, and (4) implementation fidelity was initially promoted by the CHW phone application but deterred by mobility. Maintenance showed consistent counseling sessions over time. The findings suggested the strategy was fundamentally sound but had suboptimal reach. Future iterations could consider adaptations to improve reach to priority populations, testing the need for mobile health support, and additional community sensitization to reduce stigma. CONCLUSIONS A CHW strategy to promote HIV services was implemented with moderate success in an HIV hyperendemic setting and should be considered for adoption and scale-up in other communities as part of comprehensive HIV epidemic control efforts. TRIAL REGISTRATION ClinicalTrials.gov Trial Number NCT02556957.

Abstract
Model-Informed Drug Development (MIDD) is a process that integrates drug exposure-based, biological, and statistical models to enhance the benefit-risk balance in drug development. The US Food and Drug Administration (FDA) MIDD Paired Meeting Pilot Program provides a platform to apply MIDD approaches to drug development and to seek regulatory feedback in a collaborative and streamlined process prior to submission for approval. Eli Lilly and Company (Lilly) participated in the Pilot Program to seek agency alignment to enhance the initial approved dosing regimens of cetuximab (Erbitux; Eli Lilly and Company, Indianapolis, Indiana) and ramucirumab (Cyramza; Eli Lilly and Company, Indianapolis, Indiana) without conducting additional clinical trials. Here we describe the overall MIDD strategy at Lilly, the process with the FDA, and the impact of implementing the approach.

Abstract
Background. Although research dissemination to participants and community stakeholders is a fundamental component of translational research, it rarely occurs. The objective of this study was to create a community-led, theory-based dissemination plan to engage local Black sexual minority men in an active dissemination process throughout a sexual health research study. Method. Seven focus groups (N = 38) were conducted with Black, cisgender sexual minority men aged 18 to 45 years. Findings were analyzed through thematic content analysis guided by McGuire's persuasive communication theory. Findings were used to draft a dissemination plan, which was then reviewed and edited by the study's community advisory board (CAB). The plan continues to be updated in response to community needs through CAB discussions. Results. Participants preferred messages concerning syphilis and other health concerns as well as information on local resources. Preferred sources included researchers working with trusted community organizations and leaders. Preferred channels included community events and social media, implemented with consistency. CAB feedback included expanding the target audience of dissemination efforts as well as the development of ideas for channels (i.e., events) and sources (i.e., community organizations and leaders). Additional revisions occurred in response to the COVID-19 pandemic. Conclusion. Given the continued lack of research dissemination to participant and community stakeholders, the process of developing a community-led, theory-based dissemination plan may benefit and help guide researchers to adopt this practice. It is critical that participant and community stakeholder dissemination become more highly prioritized as we strive for public health improvements and the elimination of health disparities.

Abstract
AIMS Patients with advanced urothelial carcinoma (UC) who progress after platinum-based chemotherapy have a poor prognosis, and there is a medical need to improve current treatment options. Ramucirumab plus docetaxel significantly improved progression-free survival but not overall survival (OS) in platinum-refractory advanced UC (RANGE trial; NCT02426125). Here, we report the exposure-response (ER) of ramucirumab plus docetaxel using data from the RANGE trial. METHODS Pharmacokinetic (PK) samples were collected (cycle 1-3, 5, 9 [day 1] and 30 days from treatment discontinuation), and PK data were analysed using population PK (popPK) analysis. The minimum ramucirumab concentration after first dose administration (Cmin,1 , or trough concentration immediately prior to the second dose) was derived by popPK analysis and used as the exposure parameter for ER analysis. Cox proportional hazards regression models and matched case-control analyses were used to evaluate the relationship between Cmin,1 and OS. The Cmin,1 relationship with safety was assessed descriptively. RESULTS Several poor prognostic factors (ECOG 1, haemoglobin concentration <100 g/L, presence of liver metastases) appeared more frequently in the lower exposure quartiles, suggesting a possible disease-PK interaction. A significant association was identified between Cmin,1 and OS (P = .0108). Higher exposure quartiles were associated with longer survival and smaller hazard ratios compared to placebo. No new exposure-safety trends were observed within the exposure range (ramucirumab 10 mg/kg once every 3 weeks). CONCLUSIONS This prespecified ER analyses suggests a positive relationship between efficacy and ramucirumab exposure, with an imbalance associated with disease prognostic factors. Further investigation may elucidate a possible disease-PK relationship.

Abstract
BACKGROUND Limited screening practices, minimal eating disorder training in the healthcare professions, and barriers related to help-seeking contribute to persistent low rates of eating disorder detection, significant unmet treatment need, and appreciable associated disease burden. The current review sought to broadly summarise the literature and identify gaps relating to the screening, assessment, and diagnosis of eating disorders within Western healthcare systems. METHODS This paper forms part of a Rapid Review series scoping the evidence base for the field of eating disorders, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for studies published between 2009 and mid 2021 in English. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised through purposive sampling. Data from selected studies relating to Screening, Assessment and Diagnosis of eating disorders were synthesised and are disseminated in the current review. RESULTS Eighty seven studies were identified, 38% relating to screening and 62% to assessment and diagnosis. The majority of screening studies were conducted in university student samples, showing high prevalence but only modest improvements in help-seeking in those studies that followed up post-screen. In healthcare settings, clinicians continue to have difficulty identifying eating disorder presentations, particularly Binge Eating Disorder, Other Specified Feeding or Eating Disorders, and sub-threshold eating disorders. This is preceded by inadequate and frequently homogenous screening mechanisms and exacerbated by considerable personal and health-system barriers, including self-stigma and lack of resourcing. While all groups are at risk of delayed or no diagnosis, those at particular risk include LGBTQ+ and gender diverse individuals, individuals living in larger bodies, and males. CONCLUSIONS A majority of individuals with eating disorders remain undiagnosed and untreated despite a high prevalence of these conditions and increased advocacy in recent years. Research into improving detection and clinician diagnostic skill is extremely limited. Innovative empirical research is strongly recommended to address significant individual and health-system barriers currently preventing appropriate and timely intervention for many. Limited screening in healthcare settings and low rates of eating disorder training in the healthcare professions are just some of the barriers to help-seeking which may contribute to delayed intervention and diagnosis in the eating disorders. This has significant impacts, prolonging treatment when it is finally received, and increasing healthcare costs for both the individual and the healthcare system. The current review is part of a larger Rapid Review series conducted to inform the development of Australia's National Eating Disorders Research and Translation Strategy 2021-2031. A Rapid Review is designed to comprehensively summarise a body of literature in a short timeframe, often to guide policy-making and address urgent health concerns. The Rapid Review synthesises the current evidence-base and identifies gaps in eating disorder research and care, in order to guide decision making and address urgent health concerns. This paper gives a critical overview of the scientific literature relating to the current state of screening, assessment, and diagnosis of eating disorders within Western healthcare systems that may inform health policy and research in an Australian context. It covers screening initiatives in both general and high-risk populations; personal, clinician and healthcare system challenges relating to help-seeking; and obstacles to accurate and timely clinical diagnosis across the eating disorders.

Abstract
Etiologies of HIV disparities are multifaceted; anti-LGBTQ stigma and social marginalization are contributory factors. A city health department developed a program, #ProjectPresence, exhibiting professional photos of Black LGBTQ persons in public spaces. An academic partner explored the relationship of the program to visibility, anti-LGBTQ stigma and social marginalization of Black LGBTQ persons, i.e. models, directly involved in the program and their perceptions of these relationships more broadly for community members. Brief self-administered surveys and semi-structured, in-depth interviews with #ProjectPresence models (n = 15) were conducted after the program to gather their experiences before, during and after the program. Descriptive analyses of survey responses were conducted using Stata 15.1. Interviews were audio-recorded, transcribed and analyzed in NVivo10 using categorical analysis. Surveys indicated prevalent experiences of enacted stigma (73 %) and perceptions of poor local acceptance of LGBTQ people (53 %). Interviews suggested that the program may have influenced positive individual- and community-level changes by increasing visibility of LGBTQ communities and improving acceptance among non-LGBTQ persons, inspiring personal growth and self-acceptance among models, and providing opportunities to foster new connections among LGBTQ subpopulations. Our findings suggest similar programs may present promising approaches for the reduction of stigma and social marginalization affecting LGBTQ persons and communities.

Abstract
LGBTQ + persons experience significant health inequities and medical distrust resulting from anti-LGBTQ + bias or cultural incompetence from health care workers (HCW). This program evaluation examined whether storytelling events where LGBTQ + persons shared personal and patient experiences changed HCW understanding, beliefs, and practices related to LGBTQ + patients. Five storytelling events, held biannually in Baltimore, Maryland from 2016 to 2018, were evaluated using post-event surveys, written reflections/notes during the event, and a survey of HCW in a citywide care collaborative focused on HIV prevention and treatment for LGBTQ + persons that did and did not attend a storytelling event. We analyzed surveys to measure differences in understanding, beliefs and practices and used thematic qualitative analysis of written reflections/notes from the storytelling events. 416 persons attended storytelling events; 124(30 %) completed post-event surveys and 449 written reflections/notes were collected. 56 HCW completed post-event surveys; 49(87.5 %) strongly agreed/agreed they better understood LGBTQ + patients. Emergent themes from the 43 HCW written reflections/notes included improved understanding and new approaches for engaging LGBTQ + patients. Among HCW survey respondents (n = 111), attending an event was associated with significant differences in beliefs (p = 0.024) and practices (p = 0.000) related to LGBTQ + patients. Storytelling events may serve as effective tools for increasing HCW's understanding, beliefs and practices. This strategy may ultimately help decrease anti-LGBTQ + bias, reduce medical distrust and lower barriers to HIV prevention/treatment for LGBTQ + persons.

Abstract
AIM We evaluated the safety and potential clinical impact of shortened ramucirumab infusion in Japanese patients from clinical studies. METHODS Multivariate logistic regression analysis was used to assess any association between infusion rate and increased risk of an immediate infusion-related reaction(IRR). Population pharmacokinetic modeling was used to simulate concentration-time profiles and exposure parameters following a 30- or 60-minute infusion with ramucirumab. RESULTS From 8 pooled ramucirumab clinical studies, 55 of 559(9.8%)Japanese patients experienced at least one immediate IRR(any grade). When grouped according to infusion rate quartile, the incidence of immediate any-grade IRR was similar across quartiles. Infusion rate was not significantly associated with an increased risk of an immediate IRR; odds ratio per 1 mg/min increase was 0.912, 95% confidence interval 0.724 to 1.149, p=0.436. Patients aged ≥65 years may have a reduced risk of an immediate IRR compared with those aged <65 years, and premedication use was also associated with a reduced risk. Ramucirumab pharmacokinetic profiles were comparable following a 30- or 60-minute infusion. CONCLUSIONS A shortened infusion duration of ramucirumab is unlikely to affect the efficacy or safety profile in Japanese patients and may be clinically beneficial for patients and health care providers.

Abstract
Bamlanivimab and etesevimab are neutralizing antibodies indicated for treatment of coronavirus disease 2019 (COVID-19) in patients with early mild or moderate disease. We present the use of pharmacokinetic/pharmacodynamic (PK/PD) modeling that characterizes the timecourse of viral load obtained from 2,970 patients from 2 phase II clinical trials. The model was used for identification of optimal doses that would result in at least 90% of patients achieving serum drug concentrations that result in 90% of maximum drug effect (IC90) for at least 28 days. The serum IC90 (95% confidence interval) was estimated to be 4.2 (3.2-4.3) µg/mL for bamlanivimab and 12.6 (9.7-12.8) µg/mL for etesevimab. Observed clinical trial data confirmed PK and PK/PD model predictions that doses of 700 mg bamlanivimab and 1,400 mg etesevimab would result in maximum reduction in viral load, with no additional effect seen at higher doses. No dose adjustment is recommended as age, sex, race, baseline viral load, and hepatic impairment did not have a significant impact on the PK of the antibodies. Earlier drug administration resulted in greater reductions in viral load, demonstrating the importance of receiving treatment as soon as possible. Relative to placebo, typical reduction in viral load over a 7-day period was estimated to be 80 or 93% (drug administered 4 days or 1 day after the onset of symptoms, respectively), P < 0.0001. PK/PD modeling and simulation was pivotal throughout the drug development and emergency use authorization process.

Abstract
PURPOSE We investigated the impact of infusion duration (30 and 60 min) on the pharmacokinetic profile of ramucirumab using a population pharmacokinetic (PopPK) modeling approach. We also assessed the relationship between infusion rate and incidence of immediate infusion-related reactions (IRRs; occurring on the day of administration) using ramucirumab phase II/III study data. METHODS The impact of different infusion durations (30 vs. 60 min) on the time-course of ramucirumab concentration profiles were evaluated using a PopPK model, established using ramucirumab pharmacokinetic data from 2522 patients. Logistic regression was used to evaluate the association between ramucirumab infusion rate and incidence of immediate IRRs in clinical trials. RESULTS Ramucirumab time-course concentration profiles were equivalent following a 30- or 60-min infusion. In the pooled clinical study dataset, 254 of 3216 (7.9%) patients receiving ramucirumab experienced at least one immediate IRR (any grade). When grouped according to infusion rate quartile, the incidence of immediate IRRs (any grade or grade ≥ 3) was similar across quartiles; findings were confirmed in sensitivity analyses. The risk of immediate IRRs was not found to be associated with infusion rate based on multivariate logistic analysis. CONCLUSION Shortening the infusion duration of ramucirumab from 60 to 30 min has no impact on ramucirumab exposure. Analysis of trial data found no relationship between an increased risk of immediate IRRs and a faster infusion rate. Such a change in infusion duration is unlikely to affect the clinical efficacy or overall safety profile of ramucirumab.

Abstract
191 Background: Ramucirumab is a human recombinant immunoglobin G1 monoclonal antibody (mAb) antagonist of vascular endothelial growth factor receptor-2. Ramucirumab dosed at 8 mg/kg every 2 weeks or 10 mg/kg every 3 weeks, either as monotherapy or in combination with chemotherapy, was initially studied with as an intravenous infusion over 60 minutes following premedication with a histamine-1 receptor antagonist. Lengthy intravenous infusions are inconvenient for patients and increase the workloads of nursing and administrative staff. Shortening the infusion duration of ramucirumab could therefore benefit both patients and healthcare professionals. The current analysis determined the impact such a change could have on the pharmacokinetic (PK) profile of ramucirumab. Additionally, the relationship between infusion rate and incidence of immediate infusion-related reactions (IRRs; occurring on the day of administration), common adverse events associated with mAb infusions, was assessed. Methods: A population pharmacokinetic model was established using concentration–time data collected from 2522 patients who received one of five different ramucirumab regimens involving an intravenous infusion over ~60 minutes in 17 clinical studies. The final PK model was used to simulate concentration–time profiles and exposure parameters following ramucirumab infusion durations of 30 vs 60 min. Phase II/III clinical study data from patients receiving ramucirumab were pooled to assess the association between ramucirumab infusion rate and incidence of immediate IRRs using multivariate logistic regression analysis. Results: Ramucirumab infusions of 30- and 60-min durations resulted in equivalent concentration–time profiles and, hence, equivalent systemic exposure to ramucirumab. Among 3216 patients receiving ramucirumab in phase II/III studies, 254 (7.9%) had at least one immediate any-grade IRR; 17 (0.5%) experienced grade ≥3 immediate IRRs. The incidence of immediate IRRs (any grade or grade ≥3) was similar across infusion rate quartiles. Under multivariate logistic analysis, infusion rate was not significantly associated with an increased risk of an immediate IRR (odds ratio per 1 mg/min increase 1.014, 95% confidence interval 0.999, 1.030; p=0.071). Conclusions: Administering ramucirumab using different infusion durations (30 vs 60 min) did not affect ramucirumab exposure. Analysis of clinical study data showed a faster infusion rate was not associated with an increased risk of immediate IRRs. It is considered unlikely that shortening the infusion duration of ramucirumab will impact its clinical efficacy or overall safety profile, and is now an option for administration in the U.S.

Abstract
BACKGROUND Effective implementation strategies are needed to increase engagement in HIV services in hyperendemic settings. We conducted a pragmatic cluster-randomized trial in a high-risk, highly mobile fishing community (HIV prevalence: approximately 38%) in Rakai, Uganda, to assess the impact of a community health worker-delivered, theory-based (situated Information, Motivation, and Behavior Skills), motivational interviewing-informed, and mobile phone application-supported counseling strategy called "Health Scouts" to promote engagement in HIV treatment and prevention services. METHODS AND FINDINGS The study community was divided into 40 contiguous, randomly allocated clusters (20 intervention clusters, n = 1,054 participants at baseline; 20 control clusters, n = 1,094 participants at baseline). From September 2015 to December 2018, the Health Scouts were deployed in intervention clusters. Community-wide, cross-sectional surveys of consenting 15 to 49-year-old residents were conducted at approximately 15 months (mid-study) and at approximately 39 months (end-study) assessing the primary programmatic outcomes of self-reported linkage to HIV care, antiretroviral therapy (ART) use, and male circumcision, and the primary biologic outcome of HIV viral suppression (<400 copies/mL). Secondary outcomes included HIV testing coverage, HIV incidence, and consistent condom use. The primary intent-to-treat analysis used log-linear binomial regression with generalized estimating equation to estimate prevalence risk ratios (PRR) in the intervention versus control arm. A total of 2,533 (45% female, mean age: 31 years) and 1,903 (46% female; mean age 32 years) residents completed the mid-study and end-study surveys, respectively. At mid-study, there were no differences in outcomes between arms. At end-study, self-reported receipt of the Health Scouts intervention was 38% in the intervention arm and 23% in the control arm, suggesting moderate intervention uptake in the intervention arm and substantial contamination in the control arm. At end-study, intention-to-treat analysis found higher HIV care coverage (PRR: 1.06, 95% CI: 1.01 to 1.10, p = 0.011) and ART coverage (PRR: 1.05, 95% CI: 1.01 to 1.10, p = 0.028) among HIV-positive participants in the intervention compared with the control arm. Male circumcision coverage among all men (PRR: 1.05, 95% CI: 0.96 to 1.14, p = 0.31) and HIV viral suppression among HIV-positive participants (PRR: 1.04, 95% CI: 0.98 to 1.12, p = 0.20) were higher in the intervention arm, but differences were not statistically significant. No differences were seen in secondary outcomes. Study limitations include reliance on self-report for programmatic outcomes and substantial contamination which may have diluted estimates of effect. CONCLUSIONS A novel community health worker intervention improved HIV care and ART coverage in an HIV hyperendemic setting but did not clearly improve male circumcision coverage or HIV viral suppression. This community-based, implementation strategy may be a useful component in some settings for HIV epidemic control. TRIAL REGISTRATION ClinicalTrials.gov NCT02556957.

Abstract
LESSONS LEARNED The combination of the antivascular endothelial growth factor receptor 2 monoclonal antibody, ramucirumab, and the type II MET kinase inhibitor, merestinib, is tolerable. Preliminary efficacy data suggest that the combination may provide clinical benefit to patients with metastatic colorectal cancer (mCRC). Further development of this combination would likely necessitate the identification of subsets of patients with mCRC where the clinical benefit is of clinical relevance. BACKGROUND This study evaluated safety, preliminary efficacy, and pharmacokinetics of ramucirumab plus merestinib in patients with MCR previously treated with oxaliplatin and/or irinotecan. METHODS Open-label phase Ia/b study comprising 3+3 dose-limiting toxicity (DLT) observation and expansion parts. Treatment was ramucirumab 8 mg/kg on days 1 and 15 and merestinib 80 mg once daily (QD; 28-day cycle). Primary objective was safety and tolerability. Secondary objectives were pharmacokinetics and preliminary antitumor activity. Exploratory objective was biomarker associations. RESULTS Safety findings: DLT (proteinuria) of 7 phase Ia patients (the expansion part started at the initial recommended dose level); 16 patients (70%) with grade ≥3 treatment-emergent adverse events (TEAEs); 10 patients (43%) with grade ≥3 treatment-related TEAEs. The most common grade ≥3 treatment-related TEAEs were fatigue (4 patients [17%]) and increased blood alkaline phosphatase, diarrhea, and hypertension (2 patients each [9%]). One patient discontinued treatment because of cholestatic hepatitis. Geometric mean trough concentrations at cycle 1, day 15, were ramucirumab, 24.8 μg/mL; merestinib, 130 ng/mL. No complete or partial response was seen; 12 patients (52%) achieved stable disease. Median progression-free survival was 3.3 months (95% confidence interval [CI]: 1.6-4.4). Median overall survival was 8.9 months (95% CI: 3.5-12.7). There were no associations between genetic alterations and efficacy. CONCLUSION Ramucirumab plus merestinib is tolerable and may have clinical benefit in biomarker-unselected, heavily pretreated patients with mCRC.

Abstract
LGBTQ populations, particularly Black men who have sex with men and transgender women, experience significant HIV disparities; public health messages may inadvertently stigmatize LGBTQ populations. We sought to use qualitative methods to inform a PrEP campaign. Unstructured focus groups were conducted among predominantly Black LGBTQ persons recruited through social media and events. Discussions were audio-recorded, transcribed, and analyzed in NVivo using categorical analysis. Eighty individuals participated in 13 focus groups; 80% (64) identified as sexual or gender minorities. Eighty-eight percent (70) identified as Black/African American. Four themes emerged: (1) culturally competent, community-informed, locally relevant messaging, (2) avoiding stigmatizing language or images, (3) inaccessibility of clinical language, and (4) using identity labels representing local communities and their diversity. Findings suggest PrEP campaigns need to be developed through community-informed processes to engage and avoid stigmatizing priority populations. Ongoing partnerships between public health and LGBTQ communities can facilitate development of campaigns with engaging, acceptable language.

Abstract
PURPOSE Young black gay, bisexual, and other MSM (YBMSM) that carry a disproportionate HIV burden in the US Geosocial networking applications (GSN apps) are environments that may increase HIV risk among users. This study explored the acceptability and feasibility of using these apps for HIV/sexually transmitted infection (STI) public health outreach. DESIGN Semi-structured in-depth qualitative interviews. SETTING A frequently reported GSN app for meeting sex partners by newly diagnosed HIV-infected MSM in Baltimore. PARTICIPANTS Seventeen YBMSM aged 18 to 24 (mean = 21.5/SD = 1.8) who were logged-on to the GSN app in venues or census tracts in high HIV transmission areas. METHODS Participants completed 60 to 90 minute semi-structured interviews, which were audio-recorded and transcribed. Interview data were analyzed in NVivo10 using categorical analysis and double-coded until consistency was achieved. RESULTS Participants described GSN apps as acceptable and feasible resources for public health practitioners seeking to access YBMSM to provide HIV/STI treatment and prevention services and resources. Three themes emerged: (1) the need to authenticate public health messages to distinguish from spam; (2) improved access to YBMSM including opportunities to identify and access virtual congregations of youth in non-gay-related spaces; and (3) the importance of avoiding stigmatizing YBMSM when targeting sexual health messages. CONCLUSION GSN apps have great potential as tools for identifying and engaging at-risk YBMSM. Additional work is needed to understand limitations of this medium, to develop strategies to engage YBMSM without further stigmatizing them, and to maximize their outreach potential.

Abstract
Young Black gay, bisexual and other men who have sex with men (YBMSM) carry a disproportionate HIV burden perpetuated by exposure to sexual networks with higher untreated HIV prevalence and incidence. In Baltimore, these sexual networks include high utilization of geosocial networking apps (GSN-apps). Our prior work suggests these apps can be important access points for targeted interventions like PrEP. To inform online PrEP outreach we explored YBMSM GSN-app users' exposure to and discussions about PrEP while navigating apps. We actively recruited YBMSM (n=17) age 18-24 from the GSN-app most frequently reported by newly diagnosed HIV-infected MSM in Baltimore. Participants were recruited through direct messaging within the GSN-app while logged-on in high HIV transmission areas. Participants completed 60-90 minute semi-structured interviews, which were analyzed using a 3-stage analytic coding strategy. While some participants had not heard of PrEP, the majority described mentions or conversations about PrEP on GSN-apps. Three themes emerged: (1) Mistrust of PrEP, (2) Association with sexual promiscuity, and (3) Concerns about lack of protection from other STIs. Proper messaging, accurate information, and education are needed to account for the negative perceptions that surround PrEP; otherwise, continued underuse among YBMSM will expand rather than reduce HIV disparities.

Abstract
Background We describe this case of a young gentleman presenting with acute dyspnoea on a background history of known, long-standing asthma. His dramatic presentation, notable for profound hypoxia and cyanosis, led to an unexpected additional diagnosis of type one congenital methaemoglobinaemia. Case presentation A 26-year-old Irish gentleman was transferred urgently to the emergency department resuscitation room with marked cyanosis and tachypnoea. His oxygen saturation was 70% on 100% high flow oxygen. His arterial blood gas (On Fi02 90%) demonstrated a PaO2 = 76.8 kPa, SpO2 = 99%, pCO2 = 3 kPa and pH = 7.51. A saturation gap was evident and on further analysing the arterial blood gas, the methaemoglobin level was noted to be 28%. No contributing drugs were identified. Our patient was diagnosed with type one congenital methaemoglobinaemia. He recovered well from this admission, however, has had recurrent presentations to hospital since with high methaemoglobin levels noted on each occasion. Discussion Congenital methemoglobinemia is a rare, often overlooked differential diagnosis in patients presenting with cyanosis and dyspnoea. This is the only case, to our knowledge, of a patient with both asthma and congenital methaemoglobinaemia. Congenital methaemoglobinaemia was first described in 1943 by Dr Deeny who described two siblings as suffering from 'Familial Idiopathic Methaemoglobinaemia'. The case we present is the first reported Irish case of congenital methaemoglobinaemia, we are aware of, since 1943.Current treatment strategies include high-flow oxygen, methylene blue infusion (contraindicated in glucose-6-phosphate-dehydrogenase deficiency) and red cell exchange transfusions in the emergency setting whilst oral ascorbic acid and riboflavin are preventative.

Abstract
353 Background: Recent RANGE results showed significant improvement in PFS, a non-significant positive trend in OS, increased ORR and acceptable safety with RAM+DOC vs P+DOC in UC pts (Petrylak et al. Lancet 2017; Petrylak et al. ESMO 2018, abstr 865PD). RAM ER-OS relationships in RANGE are reported here. Methods: Pts received RAM (10 mg/kg) + DOC or P + DOC (Day 1 of a 21 day cycle) until discontinuation criteria were met. Population pharmacokinetic analysis predicted RAM minimum concentrations after first dose (RAM Cmin, 1). Multivariate Cox regression & matched case control (MCC) analyses using exposure treated as a continuous covariate, or grouped as quartiles, evaluated the ER-OS relationship. Results: Several poor prognostic factors, including Bellmunt risk factors, appeared to be more frequent in the lower exposure quartiles, suggesting a possible disease-PK interaction. Increasing RAM exposure as a continuous covariate in an ER population of n=246 pts significantly ( p=0.01) associated with improvements in OS. Higher exposure quartiles trended toward longer survival & smaller HRs compared to P (Table, Q1=lowest). Conclusions: OS and ORR benefits favored Q4, a group which was associated with more favorable prognostic features and higher exposure. The observed disease-PK interaction may confound the interpretation of the ER results and warrants further exploration. Clinical trial information: NCT02426125. [Table: see text]

Abstract
Duplex ultrasonography screening for renal artery stenosis has been the object of guidelines published by four societies designed to optimize the cost-effectiveness of the examination. OBJECTIVES To determine how well guideline indications for ultrasonography matched with requests and results in our university hospital; to determine whether compliance with guidelines was predictive of renal artery stenosis; to identify guidelines predictive of presence of stenosis; and to determine whether other predictive factors can be recognized. MATERIAL AND METHODS Requests and results of 450 Duplex ultrasonography examinations of the renal arteries performed from January 1st 2014 to December 31st 2015 were compared with published guidelines. RESULTS At least one guideline indication was identified for 212 of the 450 examinations performed (47.1%). Among these examinations, renal artery stenosis≥70% was identified in 18 patients (8.0%). No case of stenosis was identified during examinations performed outside guideline indications. Factors predictive of stenosis were: compliance with guidelines (OR=21.86 [2.88; 165.8]). Predictive guidelines were: resistant hypertension in spite of appropriate treatment (OR=3.85, [1.44; 10.33], P=0.011), accelerated hypertension (OR=7.30, [1.40; 37.99], P=0.049), sudden unexplained pulmonary edema (OR=7.30, [1.40; 37.99], P=0.049), unexplained renal insufficiency (OR=3.58, [1.37; 9.37], P=0.011), unexplained renal hypotrophy (OR=16.69, [4.38; 63.69], P<0.001), renal asymmetry (OR=4.32, [1.45; 12.85], P<0.016). No other factor was predictive of renal stenosis. These examinations had therapeutic consequences in only 50% of patients. CONCLUSION This study confirms the relevance of published guidelines. The diagnostic-effectiveness of Duplex ultrasonography examinations to search for renal artery stenosis depends upon compliance with these guidelines.

Abstract
Our aim was to examine the clinicopathological features of squamous cell carcinoma (SCC) of the oral cavity and oropharynx in a group of young patients who were dignosed during a 15-year period (2000-2014). Patients' clinical details, risk factors, and survival were obtained from medical records. Formalin-fixed, paraffin-embedded, tissue was tested for high-risk human papillomavirus (HPV). The results were compared with those of a matching group of older patients. We identified 91 patients who were younger than 45 years old, and the 50 youngest patients were studied in detail. The male:female ratio was 2:1, with more tumours located in the oral cavity than in the oropharynx (35 compared with 15). HPV-related SCC was restricted to the oropharynx. When matched for site, stage and HPV status, five-year overall survival was similar in young and matched older patients (log-rank test, p=0.515). Our findings suggest that young patients with oral SCC have a disease profile similar to that of older patients with the condition. It is plausible that prognostic information generally available for oral cancers is applicable to young patients with the disease.

Abstract
117 Background: Ramucirumab (RAM) is approved for treatment of advanced gastric cancer or gastroesophageal junction adenocarcinoma with disease progression after prior platinum and/or fluoropyrimidine chemotherapy at 8 mg/kg every 2 weeks (Q2W). Previous phase 3 trials indicated that efficacy of RAM correlated with exposure. While the primary objectives of the open-label RAM monotherapy JVDB study were pharmacokinetics and safety, a secondary analysis was conducted on efficacy and safety of the 3 higher exposure regimens vs. the standard regimen. Methods: Patients ( n = 164) were randomized 1:1:1:1 to 4 treatment arms: 8 mg/kg Q2W (Arm 1), 12 mg/kg Q2W (Arm 2), 6 mg/kg every week (Arm 3), and 8 mg/kg Days 1 and 8 (D1D8) every 3 weeks (Q3W) (Arm 4). Treatment-emergent adverse events (TEAEs) were graded by NCI CTCAE v4.0. Tumor response was assessed by RECIST 1.1. Results: Median (months) progression-free survival (PFS) of the 3 arms and overall survival (OS) of 2 arms was increased compared to the standard regimen (Table). Best overall response was partial response (Arm 2, n = 4; Arm 3, n = 2). The majority of patients experienced ≥1 TEAE (81.4%); 39.1% had ≥1 Grade ≥3 event and 26.7% had ≥1 serious event. The most frequent Grade ≥3 events were fatigue (5.6%), abdominal pain (5.05%), hypertension (5.0%), anemia (4.3%), and vomiting (3.7%). Conclusions: Although the study was not powered for statistical comparisons, some trends toward improved efficacy vs. the standard regimen were observed; the greatest median PFS months and OS improvement was 1 month (Arm 2 vs. Arm 1; PFS = 2.50 vs. 1.45; OS = 6.74 vs. 5.68). Despite higher RAM exposures with the experimental regimens, the safety profile is similar to the standard dose regimen, and no unexpected safety findings were observed. Clinical trial information: NCT02443883. [Table: see text]

Abstract
Objective To compare the prevalence of work-related protective and risk factors among Black and Latino male firefighters and to examine the association of these factors to perceived stress among both ethnic groups. Design Setting Participants Participants included 1,036 male, career firefighters who self-identified as Black (n=477) or Latino (n=559) from a large fire department in a major metropolitan city in the southwestern United States. As part of a department-wide suicide prevention program conducted in 2008, participants completed an anonymous and voluntary mental health needs survey. Measures The needs survey included questions regarding prevalence of work-related protective and risk factors, the RAPS-4 to assess substance abuse problems, and the 10-item Perceived Stress Scale. Results Results of regression analyses indicated that for both Black and Latino male firefighters, alcohol abuse (β =.13, β =.22), self-reported good health (β = -.23, β =-.24) and a positive partner/spouse relationship (β =-.14, β = -.15) were related to perceived stress. In addition, having a second job (β = .12) and a sense of life calling (β =-.10) were related to perceived stress only among Latino firefighters. All associations were in the expected direction as indicated by the signs of the standardized beta coefficients (β). Conclusion Black and Latino male firefighters reported relatively high levels of perceived stress. However, there were both differences and similarities in the factors associated to perceived stress among the ethnic groups. Therefore, interventions to help firefighters reduce or manage stress need to take into account that factors associated with perceived stress may vary by ethnic group.

Abstract
Necitumumab is a second-generation, recombinant, human immunoglobulin G1, epidermal growth factor (EGFR) receptor antibody that specifically blocks the ligand binding site of EGFR. Necitumumab potentially acts by blocking ligand epidermal growth factor (EGF) binding-mediated activation of the EGFR signaling pathway, inhibiting tumor growth, angiogenesis, and anti-apoptotic mechanisms. Necitumumab inhibited the interaction of EGF and EGFR with a concentration that inhibits binding by 50 % of approximately 0.9 nM (0.13 mg/L) and demonstrated antitumor activity during in vivo experiments associated with trough plasma concentrations of approximately 40 mg/L. This work describes the population pharmacokinetics of necitumumab in cancer patients when administered with or without concomitant chemotherapy and evaluates patient characteristics that may guide dosing. Nonlinear mixed-effects modeling of serum concentration data across five clinical studies (phases I–III) indicated that necitumumab exhibited target-mediated drug disposition, commonly observed with monoclonal antibodies, and that pharmacokinetics were expected to be linear in the studied dose ranges when administered as repeated infusions. No age, sex, race, or concomitant medication factors were found influential, while weight was a statistically significant factor for both distribution and elimination. Simulations from the final model indicated that only a limited reduction in patient drug exposure variability would be achieved by weight- or body surface area-based dosing. Necitumumab effective half-life was estimated to approximately 2 weeks, and steady state was achieved within three to four cycles of treatment. The phase III dosing schedule of 800 mg dosed on days 1 and 8 of a 21-day schedule resulted in serum concentrations that exceeded the 40-mg/L threshold indicated by preclinical experiments.

Abstract
LESSONS LEARNED Ramucirumab was well tolerated in Chinese patients with advanced solid tumors, and adverse events were manageable in this study.Pharmacokinetics characteristics in Chinese patients were similar to those in other populations. Immunogenicity was not detected.No efficacy conclusion could be drawn, and further randomized studies are warranted. BACKGROUND This single-arm, nonrandomized, open-label, dose-escalation, phase I study was designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of ramucirumab in Chinese patients with advanced solid tumors that were resistant to standard therapy or no standard therapy was available. METHODS Dose escalation was a 3 + 3 design, with expansion in Cohorts 2 and 3 for PK. Ramucirumab was given intravenously at three different dosages: 6 mg/kg every 2 weeks, 10 mg/kg every 3 weeks, and 8 mg/kg every 2 weeks. Safety analyses included all patients. PK, immunogenicity, and antitumor activity were also assessed. RESULTS Among 28 patients treated, 2 experienced dose-limiting toxicity, possibly related to ramucirumab. No maximum tolerated dose was determined. All patients experienced at least one treatment-emergent adverse event. Grade ≥3 adverse event was reported for 53.6% (n = 15) of patients. PK analyses indicated that ramucirumab had low clearance, small volume of distribution, and long half-life in Chinese patients, as in other populations. Immunogenicity was not detected. No patient had complete/partial response, and 64.3% (n = 18) had stable disease with a median duration of 5.55 months (95% confidence interval: 3.38-7.13 months). CONCLUSION Ramucirumab appeared to be well tolerated in Chinese patients with advanced solid tumors. PK characteristics in Chinese patients were similar to those in other populations.

Abstract
Innovative approaches are needed to increase engagement in HIV treatment and prevention services, particularly in HIV hot spots. Here, we detail our design, training approach, and early implementation experiences of a community-based HIV intervention called "health scouts." The intervention, utilizing a novel, theory-based approach, trained 10 community residents in an HIV hot spot fishing community to use motivational interviewing strategies and a mobile phone-based counseling application. During the first 3 months, 771 residents (median 82/health scout, range 27-160) were counseled. A directly observed Motivational Interviewing Treatment Integrity scale-based evaluation found adequate performance (median score 20/25, range 11-23). The health scout intervention was feasible to implement in a high HIV-prevalence fishing community, and its impact on HIV care outcomes will be evaluated in an ongoing cluster randomized trial. If found to be effective, it may be an important strategy for responding to HIV in high-burden settings.

Abstract
AIMS This two phase study aimed to explore health care professionals' teaching and prescribing practice related to intermittent catheterisation and to identify their perceptions about the possible implementation of a mixed (single and multi-use) package for intermittent catheterization. INTRODUCTION Single-use intermittent catheters are the norm in the UK although multi-use is common in some other countries. A recent Cochrane review found no difference in complications, including urinary tract infection rates, between those using single or multi-use catheters. A flexible option of both multi-use and single use intermittent catheters could provide users with more flexible choices in self-care. However, understanding health care professionals' perspectives is one of the keys to developing a multi-use intervention. DESIGN A qualitative research framework using in-depth interviews to inform an on line survey. METHOD In-depth interviews were conducted with health care professionals based in the UK who prescribe catheters, teach intermittent catheterisation or manage an intermittent catheterisation service. The interviewees were selected to represent a range of clinical areas, experience and professions - continence advisors, urology, multiple sclerosis (MS) and spinal cord injury specialist nurses, and General Practitioners. Following framework analysis the themes and factors identified were used to develop an on-line survey which was disseminated through health care professional networks whose members saw patients who use intermittent catheters. RESULTS Nineteen health care professionals participated in the telephone interviews; 206 completed the survey. A wide range of professionals in terms of experience and specialty afforded rich information regarding the contextual issues around the teaching and prescribing of intermittent catheters. The primary finding was that health care professionals were concerned about 'minimising health risk' and maximising 'normalcy' for those using intermittent self-catheterisation. Health care professionals who worked in the acute setting or had no experience of re-use were most resistant to the re-use of catheters. Professionals requested evidence that a multi-use package would not increase the risk of developing a urinary tract infection or increase the burden of use to a patient before a mixed package would be considered. CONCLUSIONS For multi-use to be acceptable, evidence based guidelines must be available for healthcare professionals and cleaning methods must be acceptable and safe for intermittent catheter users. Further evidence may be required to establish that a mixed catheter package is equivalent to single use only, particularly for outcomes such as urinary tract infection, urethral injury and quality of life. RELEVANCE TO CLINICAL PRACTICE This paper highlights that if multi-use catheters are to be successfully introduced into clinical practice, the ease of use, safety and effectiveness of the cleaning technique will need to be convincingly demonstrated by a range of well-defined users.

Abstract
The maximum diameter of abdominal aortic aneurysm (AAA) is a key quantification parameter for disease assessment. Although it is routinely measured on 2D-ultrasound images, using a volumetric approach is expected to improve measurement reproducibility. In this work, 3D-ultrasound or computed tomography imaging of patients with AAA was combined with a minimally interactive 3D segmentation based on implicit template deformation. Segmentation usability and reproducibility were evaluated on 81 patients, showing a mean measurement time of [2;8]min per case, and Dice coefficients of 0.87±0.12 for 3D-US and 0.81±0.08 for CT. Quantification parameters included a diameter measurement from 3D-US and CT volumes with respective confidence intervals of 0.51 [-2.5;3.52]mm and 1.00 [-1.68;3.67]mm. Additional volume measurements showed confidence intervals of 0.91 [-4.17;5.99]ml for 3D-US and 4.10 [-4.11;12.30]ml for CT.

Abstract
UNLABELLED In this study, we attempt to determine the clinical characteristic and risk factors of postoperative pneumonia (POP) after hip fracture surgery in a well-defined hip fracture cohort. We find that intrinsic factors as well as major clinical interventions were all important risk factors of POP. INTRODUCTION Postoperative pneumonia (POP) is one of the major complications following hip fractures surgery. However, the risk factors of POP are not well studied in hip fracture cohorts. We attempt to determine the clinical characteristic and risk factors of POP after hip fracture surgery in a well-defined hip fracture cohort. METHODS Datasets from a prospective hip fracture cohort study with a 2-year follow-up period, from 2000 to 2011, were reanalyzed for characteristics of POP. Multivariate Cox proportional regression was used to evaluate the association between the incidence of POP and all-cause mortality. Multivariate logistic regression was used to screen for potential risk factors of POP by analyzing demographic factors, comorbidities, major clinical interventions, and hematological parameters. RESULTS In 1429 patients who underwent hip surgery, the incidence of POP was 4.9 % (n = 70). All-cause mortality of patients with POP was significantly higher than that of patients without POP at 30 days (hazard ratio (HR) 3.05, 95 % confidence intervals (CI) 1.88-4.94), 1 year (HR 1.87, 95 % CI 1.41-2.48), and 2 years (HR 1.57, 95 % CI 1.23-1.99) postoperatively. Multivariate logistic regression showed that intrinsic factors (advanced age, anemia, diabetes, prior stroke, number of comorbidities, ASA score ≥III, and some laboratory biomarkers) as well as major clinical interventions were all significant risk factors for POP. CONCLUSION Intrinsic factors and major clinical interventions were all important risk factors of POP in patients after hip fracture surgery. Targeted preventive measures to mitigate the above risk factors may help in reducing the incidence of POP.

Abstract
Retrograde signaling is a mechanism by which mitochondrial dysfunction is communicated to the nucleus for inducing a metabolic shift essential for cell survival. Previously we showed that partial mtDNA depletion in different cell types induced mitochondrial retrograde signaling pathway (MtRS) involving Ca+2 sensitive Calcineurin (Cn) activation as an immediate upstream event of stress response. In multiple cell types, this stress signaling was shown to induce tumorigenic phenotypes in immortalized cells. In this study we show that MtRS also induces p53 expression which was abrogated by Ca2+ chelators and shRNA mediated knock down of CnAβ mRNA. Mitochondrial dysfunction induced by mitochondrial ionophore, carbonyl cyanide m-chlorophenyl hydrazone (CCCP) and other respiratory inhibitors, which perturb the transmembrane potential, were equally efficient in inducing the expression of p53 and downregulation of MDM2. Stress-induced p53 physically interacted with HIF-1α and attenuated the latter’s binding to promoter DNA motifs. Additionally, p53 promoted ubiquitination and degradation of HIF-1α in partial mtDNA depleted cells. The mtDNA depleted cells, with inhibited HIF-1α, showed upregulation of glycolytic pathway genes, glucose transporter 1–4 (Glut1–4), phosphoglycerate kinase 1 (PGK1) and Glucokinase (GSK) but not of prolyl hydroxylase (PHD) isoforms. For the first time we show that p53 is induced as part of MtRS and it renders HIF-1α inactive by physical interaction. In this respect our results show that MtRS induces tumor growth independent of HIF-1α pathway.

Abstract
UNLABELLED The prognostic value of red cell distribution width (RDW) and a combination of RDW and the American Society of Anesthesiologists (ASA) score for long-term hip fracture mortality remains unknown. Our data showed that both RDW and ASA were independent risk predictors. A combination of these two parameters may provide a more powerful strategy for the prediction of hip fracture mortality. INTRODUCTION Red cell distribution width (RDW) has recently been suggested as an independent predictor of prognosis in a variety of disorders. The American Society of Anesthesiologists (ASA) system has been widely used to stratify patients for outcome evaluations. However, the prognostic value of RDW and a combination of RDW and the ASA score for long-term hip fracture mortality has yet to be studied. METHODS This prospective cohort study included 1402 subjects from 2000 to 2011 with a follow-up study over a 2 year period. Cox proportional hazards models with a bootstrap validation were used to evaluate associations of RDW, ASA, and a combination of both with long-term mortality. The global fit and the area under the receiver operating characteristic (ROC) curve (AUC) for model discrimination were further analyzed. RESULTS Both RDW and ASA exhibited as independent risk predictors of 2-year mortality. The population with elevation of either RDW or ASA increased the risk of mortality (bootstrap validated hazard ratio (HR) 1.971 95 % confidence interval (CI) [1.336-3.005] p < 0.01) while those with an increase in both assessments (bootstrap validated HR 2.667 95 % CI [1.526-4.515] p < 0.01) were at the highest risk for mortality. The addition of the combination of ASA and RDW improved the discrimination power of risk prediction models (AUC increased from 0.700 to 0.723, p < 0.05). CONCLUSION Both RDW and ASA exhibited as independent risk predictors of 2-year hip fracture mortality. The combination of these two readily available parameters may provide a more powerful and effective strategy for the assessment of all-cause mortality in hip fracture patients.
