Delirium detection in the emergency department: A diagnostic accuracy meta-analysis of history, physical examination, laboratory tests, and screening instruments. Acad Emerg Med 2024. [PMID: 38757369 DOI: 10.1111/acem.14935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 04/13/2024] [Accepted: 04/15/2024] [Indexed: 05/18/2024]
Abstract
INTRODUCTION Geriatric emergency department (ED) guidelines emphasize timely identification of delirium. This article updates previous diagnostic accuracy systematic reviews of history, physical examination, laboratory testing, and ED screening instruments for the diagnosis of delirium as well as test-treatment thresholds for ED delirium screening. METHODS We conducted a systematic review to quantify the diagnostic accuracy of approaches to identify delirium. Studies were included if they described adults aged 60 or older evaluated in the ED setting with an index test for delirium compared with an acceptable criterion standard for delirium. Data were extracted and studies were reviewed for risk of bias. When appropriate, we conducted a meta-analysis and estimated delirium screening thresholds. RESULTS Full-text review was performed on 55 studies and 27 were included in the current analysis. No studies were identified exploring the accuracy of findings on history or laboratory analysis. While two studies reported clinicians accurately rule in delirium, clinician gestalt is inadequate to rule out delirium. We report meta-analysis on three studies that quantified the accuracy of the 4 A's Test (4AT) to rule in (pooled positive likelihood ratio [LR+] 7.5, 95% confidence interval [CI] 2.7-20.7) and rule out (pooled negative likelihood ratio [LR-] 0.18, 95% CI 0.09-0.34) delirium. We also conducted meta-analysis of two studies that quantified the accuracy of the Abbreviated Mental Test-4 (AMT-4) and found that the pooled LR+ (4.3, 95% CI 2.4-7.8) was lower than that observed for the 4AT, but the pooled LR- (0.22, 95% CI 0.05-1) was similar. Based on one study the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is the superior instrument to rule in delirium. The calculated test threshold is 2% and the treatment threshold is 11%. CONCLUSIONS The quantitative accuracy of history and physical examination to identify ED delirium is virtually unexplored. The 4AT has the largest quantity of ED-based research. Other screening instruments may more accurately rule in or rule out delirium. If the goal is to rule in delirium then the CAM-ICU or brief CAM or modified CAM for the ED are superior instruments, although the accuracy of these screening tools are based on single-center studies. To rule out delirium, the Delirium Triage Screen is superior based on one single-center study.

Abstract
Background: The benefit of levothyroxine treatment of subclinical hypothyroidism (SCH) is subject to debate. This study compared treatment satisfaction between older adults with SCH using levothyroxine or placebo. Methods: We analyzed pooled individual participant data from two randomized, double-blind, placebo-controlled trials investigating the effects of levothyroxine treatment in older adults with SCH. Community-dwelling participants aged ≥65 years, with SCH (persistent thyrotropin levels 4.60-19.99 mIU/L for >3 months and normal free T4 level), were included. Intervention dose titration until thyrotropin levels normalized, with a mock dose adjustment of placebo. Treatment satisfaction was determined during the final study visit using the Treatment Satisfaction Questionnaire for Medication (TSQM), encompassing perceived effectiveness, side effects, convenience, and global satisfaction, along with the participants' desire to continue study medication after the trial. Results: We included 536 participants. At baseline, the median (interquartile range [IQR]) age was 74.9 (69.7-81.4) years, and 292 (55%) were women. The median (IQR) thyrotropin levels were 5.80 (5.10-7.00) mIU/L at baseline in both groups; at final visit, 4.97 (3.90-6.35) mIU/L in the placebo and 3.24 (2.49-4.41) mIU/L in the levothyroxine group. After treatment, the groups did not differ significantly in global satisfaction (mean difference [CI] -1.1 [-4.5 to 2.1], p = 0.48), nor in any other domain of treatment satisfaction. These results held true regardless of baseline thyrotropin levels or symptom burden. No major differences were found in the numbers of participants who wished to continue medication after the trial (levothyroxine 35% vs. placebo 27%), did not wish to continue (levothyroxine 27% vs. placebo 30%), or did not know (levothyroxine 37% vs. placebo 42%) (p = 0.14). In a subpopulation with high symptom burden from hypothyroid symptoms at baseline, those using levothyroxine more often desired to continue the medication after the trial than those using placebo (mean difference [CI]: -21.1% [-35.6% to -6.5%]). Conclusion: These pooled data from two RCTs showed no major differences in treatment satisfaction between older adults receiving levothyroxine or placebo. This finding has important implications for decision-making regarding initiating levothyroxine treatment for SCH. Our findings generally support refraining from routinely prescribing levothyroxine in older adults with SCH.

Prevalence of Frailty in European Emergency Departments (FEED): an international flash mob study. Eur Geriatr Med 2024; 15:463-470. [PMID: 38340282 PMCID: PMC10997678 DOI: 10.1007/s41999-023-00926-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 12/19/2023] [Indexed: 02/12/2024]
Abstract
INTRODUCTION Current emergency care systems are not optimized to respond to multiple and complex problems associated with frailty. Services may require reconfiguration to effectively deliver comprehensive frailty care, yet its prevalence and variation are poorly understood. This study primarily determined the prevalence of frailty among older people attending emergency care. METHODS This cross-sectional study used a flash mob approach to collect observational European emergency care data over a 24-h period (04 July 2023). Sites were identified through the European Task Force for Geriatric Emergency Medicine collaboration and social media. Data were collected for all individuals aged 65 + who attended emergency care, and for all adults aged 18 + at a subset of sites. Variables included demographics, Clinical Frailty Scale (CFS), vital signs, and disposition. European and national frailty prevalence was determined with proportions with each CFS level and with dichotomized CFS 5 + (mild or more severe frailty). RESULTS Sixty-two sites in fourteen European countries recruited five thousand seven hundred eighty-five individuals. 40% of 3479 older people had at least mild frailty, with countries ranging from 26 to 51%. They had median age 77 (IQR, 13) years and 53% were female. Across 22 sites observing all adult attenders, older people living with frailty comprised 14%. CONCLUSION 40% of older people using European emergency care had CFS 5 + . Frailty prevalence varied widely among European care systems. These differences likely reflected entrance selection and provide windows of opportunity for system configuration and workforce planning.

Core requirements of frailty screening in the emergency department: an international Delphi consensus study. Age Ageing 2024; 53:afae013. [PMID: 38369629 PMCID: PMC10874925 DOI: 10.1093/ageing/afae013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 10/24/2023] [Indexed: 02/20/2024] Open
Abstract
INTRODUCTION Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study. METHODS A two-round electronic Delphi involving 37 participants from 10 countries was undertaken. Statements were generated from a prior systematic review examining frailty screening instruments in ED (logistic, psychometric and clinimetric properties). Reflexive thematic analysis generated a list of 56 statements for Round 1 (August-September 2021). Four main themes identified were: (i) principles of frailty screening, (ii) practicalities and logistics, (iii) frailty domains and (iv) frailty risk factors. RESULTS In Round 1, 13/56 statements (23%) were accepted. Following feedback, 22 new statements were created and 35 were re-circulated in Round 2 (October 2021). Of these, 19 (54%) were finally accepted. It was agreed that ideal frailty screens should be short (<5 min), multidimensional and well-calibrated across the spectrum of frailty, reflecting baseline status 2-4 weeks before presentation. Screening should ideally be routine, prompt (<4 h after arrival) and completed at first contact in ED. Functional ability, mobility, cognition, medication use and social factors were identified as the most important variables to include. CONCLUSIONS Although a clear consensus was reached on important requirements of frailty screening in ED, and variables to include in an ideal screen, more research is required to operationalise screening in clinical practice.

Association of Biological Age with Tumor Microenvironment in Patients with Esophageal Adenocarcinoma. Gerontology 2024; 70:337-350. [PMID: 38286115 PMCID: PMC11008718 DOI: 10.1159/000536471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Accepted: 01/20/2024] [Indexed: 01/31/2024] Open
Abstract
INTRODUCTION Esophageal cancer is the seventh most common cancer worldwide and typically tends to manifest at an older age. Marked heterogeneity in time-dependent functional decline in older adults results in varying grades of clinically manifest patient fitness or frailty. The biological age-related adaptations that accompany functional decline have been shown to modulate the non-malignant cells comprising the tumor microenvironment (TME). In the current work, we studied the association between biological age and TME characteristics in patients with esophageal adenocarcinoma. METHODS We comparatively assessed intratumoral histologic stroma quantity, tumor immune cell infiltrate, and blood leukocyte and thrombocyte count in 72 patients stratified over 3 strata of biological age (younger <70 years, fit older ≥70 years, and frail older adults ≥70 years), as defined by a geriatric assessment. RESULTS Frailty in older adults was predictive of decreased intratumoral stroma quantity (B = -14.66% stroma, p = 0.022) relative to tumors in chronological-age-matched fit older adults. Moreover, in comparison to younger adults, frail older adults (p = 0.032), but not fit older adults (p = 0.302), demonstrated a lower blood thrombocyte count at the time of diagnosis. Lastly, we found an increased proportion of tumors with a histologic desert TME histotype, comprising low stroma quantity and low immune cell infiltration, in frail older adults. CONCLUSION Our results illustrate the stromal-reprogramming effects of biological age and provide a biological underpinning for the clinical relevance of assessing frailty in patients with esophageal adenocarcinoma, further justifying the need for standardized geriatric assessment in geriatric cancer patients.

A study protocol of external validation of eight COVID-19 prognostic models for predicting mortality risk in older populations in a hospital, primary care, and nursing home setting. Diagn Progn Res 2023; 7:8. [PMID: 37013651 PMCID: PMC10069944 DOI: 10.1186/s41512-023-00144-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 01/27/2023] [Indexed: 04/05/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic has a large impact worldwide and is known to particularly affect the older population. This paper outlines the protocol for external validation of prognostic models predicting mortality risk after presentation with COVID-19 in the older population. These prognostic models were originally developed in an adult population and will be validated in an older population (≥ 70 years of age) in three healthcare settings: the hospital setting, the primary care setting, and the nursing home setting. METHODS Based on a living systematic review of COVID-19 prediction models, we identified eight prognostic models predicting the risk of mortality in adults with a COVID-19 infection (five COVID-19 specific models: GAL-COVID-19 mortality, 4C Mortality Score, NEWS2 + model, Xie model, and Wang clinical model and three pre-existing prognostic scores: APACHE-II, CURB65, SOFA). These eight models will be validated in six different cohorts of the Dutch older population (three hospital cohorts, two primary care cohorts, and a nursing home cohort). All prognostic models will be validated in a hospital setting while the GAL-COVID-19 mortality model will be validated in hospital, primary care, and nursing home settings. The study will include individuals ≥ 70 years of age with a highly suspected or PCR-confirmed COVID-19 infection from March 2020 to December 2020 (and up to December 2021 in a sensitivity analysis). The predictive performance will be evaluated in terms of discrimination, calibration, and decision curves for each of the prognostic models in each cohort individually. For prognostic models with indications of miscalibration, an intercept update will be performed after which predictive performance will be re-evaluated. DISCUSSION Insight into the performance of existing prognostic models in one of the most vulnerable populations clarifies the extent to which tailoring of COVID-19 prognostic models is needed when models are applied to the older population. Such insight will be important for possible future waves of the COVID-19 pandemic or future pandemics.

The effect of thyroid hormone therapy on muscle function, strength and mass in older adults with subclinical hypothyroidism-an ancillary study within two randomized placebo controlled trials. Age Ageing 2023; 52:7008632. [PMID: 36721961 DOI: 10.1093/ageing/afac326] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND loss of skeletal muscle function, strength and mass is common in older adults, with important socioeconomic impacts. Subclinical hypothyroidism is common with increasing age and has been associated with reduced muscle strength. Yet, no randomized placebo-controlled trial (RCT) has investigated whether treatment of subclinical hypothyroidism affects muscle function and mass. METHODS this is an ancillary study within two RCTs conducted among adults aged ≥65 years with persistent subclinical hypothyroidism (thyrotropin (TSH) 4.60-19.99 mIU/l, normal free thyroxine). Participants received daily levothyroxine with TSH-guided dose adjustment or placebo and mock titration. Primary outcome was gait speed at final visit (median 18 months). Secondary outcomes were handgrip strength at 1-year follow-up and yearly change in muscle mass. RESULTS we included 267 participants from Switzerland and the Netherlands. Mean age was 77.5 years (range 65.1-97.1), 129 (48.3%) were women, and their mean baseline TSH was 6.36 mIU/l (standard deviation [SD] 1.9). At final visit, mean TSH was 3.8 mIU/l (SD 2.3) in the levothyroxine group and 5.1 mIU/l (SD 1.8, P < 0.05) in the placebo group. Compared to placebo, participants in the levothyroxine group had similar gait speed at final visit (adjusted between-group mean difference [MD] 0.01 m/s, 95% confidence interval [CI] -0.06 to 0.09), similar handgrip strength at one year (MD -1.22 kg, 95% CI -2.60 to 0.15) and similar yearly change in muscle mass (MD -0.15 m2, 95% CI -0.49 to 0.18). CONCLUSIONS in this ancillary analysis of two RCTs, treatment of subclinical hypothyroidism did not affect muscle function, strength and mass in individuals 65 years and older.

Abstract
Abstract
BACKGROUND AND AIMS
The growing population of older patients with chronic kidney disease (CKD) often faces unidentified cognitive impairments and high prevalence of depressive symptoms. Apathy is a clinical syndrome associated with both depression and cognitive decline in community-dwelling older people. Furthermore, apathy has been more often linked to vascular impairments, which are also highly prevalent in the CKD population. However, so far, prevalence and consequences of apathy in older CKD patients have not been studied.
We aimed (1) to investigate the prevalence of apathy symptoms in an older population with CKD stage G4/G5 (eGFR < 20 mL/min/1.73 m2), and (2) to assess if apathy is associated with, frailty, cognitive and functional impairments and mood. In addition, we (3) investigated the relation between apathy at baseline and mortality during four years of follow-up.
METHOD
Data was used from the prospective multicenter COPE (Cognitive Decline in Older Patients with ESKD) cohort, which included CKD patients aged ≥65 years with an eGFR of ≤20 mL/min/1.73 m2. Symptoms of apathy were assessed with the 3-item subscale of the 15-item Geriatric Depression (GDS-3A score ≥2) and depressive symptoms with the remaining items of this scale (GDS-12D ≥2). Frailty, (Fried Frailty Index ≥3), functional dependence (GARS score), handgrip strength and walking speed were measured. Cognitive functioning was assessed by means of global cognition (Mini Mental State Examination), visuoconstruction (Clock drawing), memory (15-Word Verbal Learning Test and Visual Association Test), executive function (Trail Making Test-B) and psychomotor speed (Letter Digit Substitution Test, Trail Making Test -A).
Cross-sectional correlations between groups were tested with t-tests, Mann–Whitney and Chi-squared tests. Hazard ratio for mortality was analysed with Cox regression adjusting for age, gender and primary vascular kidney disease.
RESULTS
In total n = 180 patients, 67% male, were included with a median age of 75.5 years (IQR 71.0–80.9) and mean eGFR of 16.5 (SD 4.6). Symptoms of apathy and isolated apathy (i.e. with no symptoms of depression) were seen in respectively 36% (n = 64) and 17% (n = 30) of the study population. Presence of apathy symptoms at baseline was associated with primary vascular kidney disease (P = 0.031), depression (P < 0.001), frailty (P < 0.001) and decreased physical functioning (i.e. functional dependence; P < 0.001, handgrip strength; P = 0.026 and walking speed; P < 0.001). Presence of apathy symptoms was also associated with reduced executive function (P = 0.045) and psychomotor speed (P = 0.022). Furthermore, patients with apathy symptoms had a 1.9 times higher mortality risk (P = 0.022, adjusted for age, gender and primary vascular renal disease).
CONCLUSION
Symptoms of apathy occurred in one third of this cohort of older advanced CKD patients. Although apathy was associated with presence of depressive symptoms, half of the cases were not. Apathy is associated with multiple functional and cognitive measures and two-fold increased mortality. Future investigations should focus on cause of apathy and its value in predicting cognitive decline in older CKD patients. Because of the relation of apathy with future outcomes, assessment of apathy might be of value in shared decision making on renal replacement therapy in older CKD patients.

Abstract
Abstract
BACKGROUND AND AIMS
Dialysis might not benefit all older patients with kidney failure, particularly those with multi-morbid conditions and frailty. Awareness of the presence of geriatric impairments has the potential to improve outcomes by tailoring treatment plans and decisions for individual patients. Geriatric assessment has been recommended in guidelines to support shared decision making (SDM) in older patients with kidney failure. We aimed to describe the perspectives of patients and healthcare professionals on the Nephro-Geriatric Assessment (NGA) as a SDM tool for treatment choice in older patients approaching kidney failure (eGFR)<20 mL/min/1.73 m2).
METHOD
Patients (N = 18) with kidney failure, caregivers (N = 4) and professionals (N = 25) were purposively sampled from three university medical centre initiatives and seven regional hospitals from different provinces in the Netherlands. Six semi-structured focus groups were held to discuss participants’ experiences with and perspectives on NGA as an aid to SDM in their choices to start or forego dialysis. Transcripts were analysed inductively using thematic analysis.
RESULTS
Professionals reported that NGA, performed prior to SDM about kidney replacement therapy (KRT), creates awareness of patients’ possibilities but also of their limitations. Somatic frailty is unearthed alongside in-depth knowledge about patients’ social system and psychological wellbeing––information they consider vital for good quality SDM relative to KRT. Professionals reported NGA as being a valuable tool to initiate discussions on treatment decisions and patient goals, and improve awareness to (re)consider different treatment options. Although patients and caregivers had positive attitudes towards NGA, they were mostly unaware of the purpose and role that NGA could play in SDM about KRT. Several interconnecting themes, which could facilitate or hinder SDM in kidney failure were identified and grouped under three main themes: (1) patient psycho-social situation: social support system and who influences decisions (e.g. choosing to dialyze due to family pressure), trusting patient–professional relationships, patient emotions (e.g. anxiety about being a burden to family and society), quality of life and life goals; (2) on modality choice: medical history and frailty, patient character and attitudes (e.g. an optimistic or pessimistic view of life), health-related information and education, continual assessment of situation; (3) organization of health care: multidisciplinary approach, consultation with geriatrician, early referral to kidney failure care and consultation time.
CONCLUSION
Professionals confirmed the benefits of NGA as a tool to identify geriatric impairments in older patients approaching kidney failure and how integration of its outcomes can facilitate a more holistic approach to inform choices about KRT based on patient values, expectations and goals. Recognition of supporting factors and resolution of impeding factors to SDM about KRT can be beneficial for good SDM. Our study underscores the importance of clear patient–professional communication. Conducting NGA provides anchors to include information on geriatric impairments, which is potentially valuable for the prevention of decisional regret.

Abstract
BACKGROUND older people remain underrepresented in clinical trials, and evidence generated in younger populations cannot always be generalized to older patients. OBJECTIVE to identify key barriers and to discuss solutions to specific issues affecting recruitment and retention of older participants in clinical trials based on experience gained from six current European randomised controlled trials (RCTs) focusing on older people. METHODS a multidisciplinary group of experts including representatives of the six RCTs held two networking conferences and compiled lists of potential barriers and solutions. Every item was subsequently allocated points by each study team according to how important it was perceived to be for their RCTs. RESULTS the six RCTs enrolled 7,612 older patients. Key barriers to recruitment were impaired health status, comorbidities and diverse health beliefs including priorities within different cultural systems. All trials had to increase the number of recruitment sites. Other measures felt to be effective included the provision of extra time, communication training for the study staff and a re-design of patient information. Key barriers for retention included the presence of severe comorbidities and the occurrence of adverse events. Long study duration, frequent study visits and difficulties accessing the study site were also mentioned. Solutions felt to be effective included spending more time maintaining close contact with the participants, appropriate measures to show appreciation and reimbursement of travel arrangements. CONCLUSION recruitment and retention of older patients in trials requires special recognition and a targeted approach. Our results provide scientifically-based practical recommendations for optimizing future studies in this population.

Abstract
Glycemic traits are used to diagnose and monitor type 2 diabetes and cardiometabolic health. To date, most genetic studies of glycemic traits have focused on individuals of European ancestry. Here we aggregated genome-wide association studies comprising up to 281,416 individuals without diabetes (30% non-European ancestry) for whom fasting glucose, 2-h glucose after an oral glucose challenge, glycated hemoglobin and fasting insulin data were available. Trans-ancestry and single-ancestry meta-analyses identified 242 loci (99 novel; P < 5 × 10-8), 80% of which had no significant evidence of between-ancestry heterogeneity. Analyses restricted to individuals of European ancestry with equivalent sample size would have led to 24 fewer new loci. Compared with single-ancestry analyses, equivalent-sized trans-ancestry fine-mapping reduced the number of estimated variants in 99% credible sets by a median of 37.5%. Genomic-feature, gene-expression and gene-set analyses revealed distinct biological signatures for each trait, highlighting different underlying biological pathways. Our results increase our understanding of diabetes pathophysiology by using trans-ancestry studies for improved power and resolution.

Abstract
Abstract
Background and Aims
Unidentified cognitive decline and other geriatric impairments are prevalent in older patients with advanced kidney disease. Despite guideline recommendation of geriatric evaluation, routine geriatric assessment is not common in these patients. While high burden of vascular disease and existing pre-dialysis care pathways mandate a tailored geriatric assessment, no consensus exists on which instruments are most suitable in this population to identify geriatric impairments. Therefore, the aim of this study was to propose a geriatric assessment, based on multidisciplinary consensus, for older people with advanced chronic kidney disease.
Method
A pragmatic approach was chosen to reach agreement on a suitable set of instruments to routinely identify major geriatric impairments in older patients with advanced chronic kidney disease. This approach included focus group meetings to identify criteria for the assessment, literature review to identify potential instruments, questionnaire to inventory currently used instruments, an expert consensus meeting to ensure that the selection of tests was based on input from clinical experience in nephrology and geriatrics, and pilot testing to ensure practicability. In preparation of the consensus meeting we composed a project team and an expert panel (n=33), drafted selection criteria for the selection of instruments, and assessed potential instruments for the test-set.
Results
Selection criteria related to general geriatric domains, clinical relevance, feasibility and duration of the assessment. The consensus-set contains instruments in functional, cognitive, psychological, somatic, patient preferences, nutritional status, and social domains (Figure 1). Administration of (seven) patient questionnaires and (ten) professional-administered instruments, by nurse (practitioners), takes estimated 20 and 40 minutes, respectively. Results are discussed in a multi-disciplinary meeting including at least nephrology and geriatric expertise, informing nephrology treatment decisions and follow-up interventions amongst which comprehensive geriatric assessment.
Conclusion
This first multi-disciplinary consensus on nephrology-tailored geriatric assessment intent to benefit clinical care and enhance research comparability for older patients with advanced chronic kidney disease. The proposed geriatric assessment is currently implemented in multiple hospitals and studies. Future initiatives and studies should provide insights on effectiveness, feasibility, patient’s satisfaction and, value for shared treatment decision making and outcome improvement.

Abstract
9544 Background: Checkpoint inhibitors have strongly improved survival of patients with metastatic melanoma. Trials suggest no differences in outcomes between older and younger patients, but only relatively young patients with a good performance status were included in these trials. The aim of this study was to describe treatment patterns and outcomes of older adults with metastatic melanoma, and to identify predictors of outcome. Methods: We included all patients aged ≥65 years with metastatic melanoma between 2013 and 2020 from the Dutch Melanoma Treatment registry (DMTR), in which detailed information on patients, treatments and outcomes is available. We assessed predictors of grade ≥3 toxicity and 6-months response using logistic regression models, and melanoma-specific and overall survival using Cox regression models. Additionally, we described reasons for hospital admissions and treatment discontinuation. Results: A total of 2216 patients were included. Grade ≥3 toxicity did not increase with age, comorbidity or WHO performance status, in patients treated with monotherapy (anti-PD1 or ipilimumab) or combination treatment. However, patients aged ≥75 were admitted more frequently and discontinued treatment due to toxicity more often. Six months-response rates were similar to previous randomized trials (40.3% and 43.6% in patients aged 65-75 and ≥75 respectively for anti-PD1 treatment) and were not affected by age or comorbidity. Melanoma-specific survival was not affected by age or comorbidity, but age, comorbidity and WHO performance status were associated with overall survival in multivariate analyses. Conclusions: Toxicity, response and melanoma-specific survival were not associated with age or comorbidity status. Treatment with immunotherapy should therefore not be omitted solely based on age or comorbidity. However, the impact of grade I-II toxicity in older patients deserves further study as older patients discontinue treatment more frequently and receive less treatment cycles.[Table: see text]

Circulating angiopoietin-2 and angiogenic microRNAs associate with cerebral small vessel disease and cognitive decline in older patients reaching end stage renal disease. Nephrol Dial Transplant 2020; 37:498-506.

Abstract
BACKGROUND The prevalence of end-stage renal disease (ESRD) is increasing worldwide, with the majority of new ESRD cases diagnosed in patients aged >60 years. These older patients are at increased risk for impaired cognitive functioning, potentially through cerebral small vessel disease (SVD). Novel markers of vascular integrity may be of clinical value for identifying patients at high risk for cognitive impairment. METHODS We aimed to associate the levels of Angiopoietin-2 (Ang-2), asymmetric dimethylarginine (ADMA), and a selection of eight circulating angiogenic miRNAs with SVD and cognitive impairment in older patients reaching ESRD that did not initiate renal replacement therapy yet (n = 129; mean age 75.3 years; mean eGFR 16.4 mL/min). We assessed brain MRI changes of SVD (white matter hyperintensity volume, microbleeds and presence of lacunes) and measures of cognition in domains of memory, psychomotor speed and executive function, comprised in a neuropsychological test battery. RESULTS Older patients reaching ESRD showed an unfavorable angiogenic profile, as indicated by aberrant levels of Ang-2 and five angiogenic miRNAs (miR-27a, miR-126, miR-132, miR-223, miR-326), compared to healthy persons and patients with diabetic nephropathy. Moreover, Ang-2 associated with SVD and with the domains of psychomotor speed and executive function, while miR-223 and miR-29a associated with memory function. CONCLUSIONS Taken together, these novel angiogenic markers might serve to identify older patients with ESRD at risk of cognitive decline, as well as give insight into the underlying (vascular) pathophysiology.

The effect of levothyroxine therapy on depressive symptoms in adults with subclinical hypothyroidism. Eur J Public Health 2020.

Abstract
Abstract
Background
Levothyroxine is one of the most commonly prescribed drugs. A common reason for levothyroxine treatment on patients with subclinical hypothyroidism are depressive symptoms. A meta-analysis of four RCTs (n = 278) found no benefit of levothyroxine therapy on depressive symptoms. However, the confidence interval does not exclude a small clinical benefit. We aim to assess the effect of levothyroxine therapy for depressive symptoms in patients with subclinical hypothyroidism using data from a RCT with more than 400 adults.
Methods
The TRUST trial was a double-blind, randomized, placebo-controlled trial involving adults aged ≥65y with subclinical hypothyroidism (elevated TSH levels (4.6-19.9 mU/L) and free thyroxine within the reference range). The outcome was depressive symptoms after 12 months based on the Geriatric Depression Scale (GDS-15), a 15-item questionnaire (range: 0 to 15, higher scores indicate more depressive symptoms, minimal clinical important difference: 2). The multivariable linear regression model was adjusted for levothyroxine starting dose, sex, site, and GDS-15 baseline score.
Results
425 Swiss and Dutch adults with subclinical hypothyroidism were randomised (mean age 75y, 56% female). The mean (SD) TSH was 6.6 (2.1) mU/L at baseline and after 12 months decreased to 3.8 (2.3) mU/L in the levothyroxine group vs 5.9 (2.7) mU/L in the placebo group. At baseline, the mean GDS-15 score was 1.3 (1.9) in the levothyroxine group and 1.0 (1.6) in the placebo group. The mean GDS-15 score at 12 months was 1.4 (2.1) in the levothyroxine and 1.1 (1.7) in the placebo group with an adjusted between-group difference of 0.2 for levothyroxine vs. placebo (95% CI:-0.1 to 0.5; p = 0.29).
Conclusions
In this by far largest RCT on the topic, levothyroxine therapy did not confer a benefit for depressive symptoms. Consequently, our results do not support the practice of prescribing levothyroxine for depressive symptoms when they co-occur with subclinical hypothyroidism.
Key messages
Levothyroxine has no benefit on depressive symptoms in patients with subclinical hypothyroidism. Levothyroxine prescription to patients with subclinical hypothyroidism and depressive symptoms should be reconsidered.

Abstract
BACKGROUND L-thyroxine does not improve hypothyroid symptoms among adults with subclinical hypothyroidism (SCH). However, those with greater symptom burden before treatment may still benefit. OBJECTIVE To determine whether L-thyroxine improves hypothyroid symptoms and tiredness among older adults with SCH and greater symptom burden. DESIGN Secondary analysis of the randomized, placebo-controlled trial TRUST (Thyroid Hormone Replacement for Untreated Older Adults with Subclinical Hypothyroidism Trial). (ClinicalTrials.gov: NCT01660126). SETTING Switzerland, Ireland, the Netherlands, and Scotland. PARTICIPANTS 638 persons aged 65 years or older with persistent SCH (thyroid-stimulating hormone level of 4.60 to 19.9 mIU/L for >3 months and normal free thyroxine level) and complete outcome data. INTERVENTION L-thyroxine or matching placebo with mock dose titration. MEASUREMENTS 1-year change in Hypothyroid Symptoms and Tiredness scores (range, 0 to 100; higher scores indicate more symptoms) on the Thyroid-Related Quality-of-Life Patient-Reported Outcome Questionnaire among participants with high symptom burden (baseline Hypothyroid Symptoms score >30 or Tiredness score >40) versus lower symptom burden. RESULTS 132 participants had Hypothyroid Symptoms scores greater than 30, and 133 had Tiredness scores greater than 40. Among the group with high symptom burden, the Hypothyroid Symptoms score improved similarly between those receiving L-thyroxine (mean within-group change, -12.3 [95% CI, -16.6 to -8.0]) and those receiving placebo (mean within-group change, -10.4 [CI, -15.3 to -5.4]) at 1 year; the adjusted between-group difference was -2.0 (CI, -5.5 to 1.5; P = 0.27). Improvements in Tiredness scores were also similar between those receiving L-thyroxine (mean within-group change, -8.9 [CI, -14.5 to -3.3]) and those receiving placebo (mean within-group change, -10.9 [CI, -16.0 to -5.8]); the adjusted between-group difference was 0.0 (CI, -4.1 to 4.0; P = 0.99). There was no evidence that baseline Hypothyroid Symptoms score or Tiredness score modified the effects of L-thyroxine versus placebo (P for interaction = 0.20 and 0.82, respectively). LIMITATION Post hoc analysis, small sample size, and examination of only patients with 1-year outcome data. CONCLUSION In older adults with SCH and high symptom burden at baseline, L-thyroxine did not improve hypothyroid symptoms or tiredness compared with placebo.

Abstract
Importance Increased free thyroxine (FT4) and decreased thyrotropin are associated with increased risk of atrial fibrillation (AF) in observational studies, but direct involvement is unclear. Objective To evaluate the potential direct involvement of thyroid traits on AF. Design, Setting, and Participants Study-level mendelian randomization (MR) included 11 studies, and summary-level MR included 55 114 AF cases and 482 295 referents, all of European ancestry. Exposures Genomewide significant variants were used as instruments for standardized FT4 and thyrotropin levels within the reference range, standardized triiodothyronine (FT3):FT4 ratio, hypothyroidism, standardized thyroid peroxidase antibody levels, and hyperthyroidism. Mendelian randomization used genetic risk scores in study-level analysis or individual single-nucleotide polymorphisms in 2-sample MR for the summary-level data. Main Outcomes and Measures Prevalent and incident AF. Results The study-level analysis included 7679 individuals with AF and 49 233 referents (mean age [standard error], 62 [3] years; 15 859 men [29.7%]). In study-level random-effects meta-analysis, the pooled hazard ratio of FT4 levels (nanograms per deciliter) for incident AF was 1.55 (95% CI, 1.09-2.20; P = .02; I2 = 76%) and the pooled odds ratio (OR) for prevalent AF was 2.80 (95% CI, 1.41-5.54; P = .003; I2 = 64%) in multivariable-adjusted analyses. The FT4 genetic risk score was associated with an increase in FT4 by 0.082 SD (standard error, 0.007; P < .001) but not with incident AF (risk ratio, 0.84; 95% CI, 0.62-1.14; P = .27) or prevalent AF (OR, 1.32; 95% CI, 0.64-2.73; P = .46). Similarly, in summary-level inverse-variance weighted random-effects MR, gene-based FT4 within the reference range was not associated with AF (OR, 1.01; 95% CI, 0.89-1.14; P = .88). However, gene-based increased FT3:FT4 ratio, increased thyrotropin within the reference range, and hypothyroidism were associated with AF with inverse-variance weighted random-effects OR of 1.33 (95% CI, 1.08-1.63; P = .006), 0.88 (95% CI, 0.84-0.92; P < .001), and 0.94 (95% CI, 0.90-0.99; P = .009), respectively, and robust to tests of horizontal pleiotropy. However, the subset of hypothyroidism single-nucleotide polymorphisms involved in autoimmunity and thyroid peroxidase antibodies levels were not associated with AF. Gene-based hyperthyroidism was associated with AF with MR-Egger OR of 1.31 (95% CI, 1.05-1.63; P = .02) with evidence of horizontal pleiotropy (P = .045). Conclusions and Relevance Genetically increased FT3:FT4 ratio and hyperthyroidism, but not FT4 within the reference range, were associated with increased AF, and increased thyrotropin within the reference range and hypothyroidism were associated with decreased AF, supporting a pathway involving the pituitary-thyroid-cardiac axis.

Abstract
CONTEXT Both thyroid dysfunction and levothyroxine (LT4) therapy have been associated with bone loss, but studies on the effect of LT4 for subclinical hypothyroidism (SHypo) on bone yielded conflicting results. OBJECTIVE To assess the effect of LT4 treatment on bone mineral density (BMD), Trabecular Bone Score (TBS), and bone turnover markers (BTMs) in older adults with SHypo. DESIGN AND INTERVENTION Planned nested substudy of the double-blind placebo-controlled TRUST trial. Participants with SHypo were randomized to LT4 with dose titration versus placebo with computerized mock titration. SETTING AND PARTICIPANTS 196 community-dwelling adults over 65 years enrolled at the Swiss TRUST sites had baseline and 1-year follow-up bone examinations; 4 participants withdrew due to adverse events not related to treatment. MAIN OUTCOME MEASURES One-year percentage changes of BMD, TBS, and 2 serum BTMs (serum CTX-1 [sCTX] and procollagen type 1 N-terminal polypeptide [P1NP]). Student's t-test for unadjusted analyses and linear regression adjusted for clinical center and sex were performed. RESULTS Mean age was 74.3 years ± 5.7, 45.4% were women, and 19.6% were osteoporotic. The unadjusted 1-year change in lumbar spine BMD was similar between LT4 (+0.8%) and placebo-treated groups (-0.6%; between-groups difference +1.4%: 95% confidence interval [CI] -0.1 to 2.9, P = .059). Likewise, there were no between-group differences in 1-year change in TBS (-1.3%: 95% CI -3.1 to 0.6, P = .19), total hip BMD (-0.2%: 95% CI -1.1 to 0.1, P = .61), or BTMs levels (sCTX +24.1%: 95% CI -7.9 to 56.2, P = .14), or after adjustment for clinical centers and sex. CONCLUSIONS Over 1-year levothyroxine had no effect on bone health in older adults with SHypo. REGISTRATION ClinicalTrial.gov NCT01660126 and NCT02491008.

Abstract
BACKGROUND There is little evidence comparing the role of subjective versus objective indicators of socioeconomic status (SES) on individuals' self-rated health (SRH) in Iran. OBJECTIVES We aimed to investigate underlying predictors of SRH including subjective and objective SES in Tehran, a multi-ethnic city. METHOD This is an analysis of cross-sectional survey data on subjective and objective SES from a population-based case-control study conducted in Tehran, Iran (2015). We used random digit dialing for study sample recruitment. Linear regression models were used for estimating crude and adjusted coefficients (95% confidence intervals). Age, gender, SES as well as cigarette smoking were included as confounders. RESULTS 15-50 years old residents of Tehran were recruited in the study (n = 1057). High reported objective and subjective SES was consistently associated with a better SRH. Subjective current SES (p < .001), subjective adolescence SES (p = .018), change in subjective SES (current vs. adolescent) (p = .034) and participants' education years (p < .001). Improvements over time in current SES in comparison to SES rated during adolescence increased the participants' SRH after adjustment for potential confounders (coefficient = 0.170, 95% CI: (0.015, 0.325)). Female participants (coefficient = -0.305, 95% CI: (-0.418, -0.192)) and smokers (high category vs. never smokers) (coefficient = -0.456, 95% CI: (-0.714, -0.197)) reported significantly worse SRH. Increasing age - 0.008 (95% CI: -0.014, -0.002) was associated with decreased SRH. CONCLUSION High subjective and objective SES consistently was the most important predictor of high SRH.

Abstract
IMPORTANCE The benefit of thyroid hormone therapy for subclinical hypothyroidism is uncertain. New evidence from recent large randomized clinical trials warrants an update of previous meta-analyses. OBJECTIVE To conduct a meta-analysis of the association of thyroid hormone therapy with quality of life and thyroid-related symptoms in adults with subclinical hypothyroidism. DATA SOURCES PubMed, EMBASE, ClinicalTrials.gov, Web of Science, Cochrane Library, CENTRAL, Emcare, and Academic Search Premier from inception until July 4, 2018. STUDY SELECTION Randomized clinical trials that compared thyroid hormone therapy with placebo or no therapy in nonpregnant adults with subclinical hypothyroidism were eligible. Two reviewers independently evaluated eligibility based on titles and abstracts of all retrieved studies. Studies not excluded in this first step were independently assessed for inclusion after full-text evaluation by 2 reviewers. DATA EXTRACTION AND SYNTHESIS Two independent reviewers extracted data, assessed risk of bias (Cochrane risk-of-bias tool), and evaluated the quality of evidence (GRADE tool). For synthesis, differences in clinical scores were transformed (eg, quality of life) into standardized mean differences (SMDs; positive values indicate benefit of thyroid hormone therapy; 0.2, 0.5, and 0.8 correspond to small, moderate, and large effects, respectively). Random-effects models for meta-analyses were applied. MAIN OUTCOMES AND MEASURES General quality of life and thyroid-related symptoms after a minimum follow-up of 3 months. RESULTS Overall, 21 of 3088 initially identified publications met the inclusion criteria, with 2192 adults randomized. After treatment (range, 3-18 months), thyroid hormone therapy was associated with lowering the mean thyrotropin value into the normal reference range compared with placebo (range, 0.5-3.7 mIU/L vs 4.6 to 14.7 mIU/L) but was not associated with benefit regarding general quality of life (n = 796; SMD, -0.11; 95% CI, -0.25 to 0.03; I2=66.7%) or thyroid-related symptoms (n = 858; SMD, 0.01; 95% CI, -0.12 to 0.14; I2=0.0%). Overall, risk of bias was low and the quality of evidence assessed with the GRADE tool was judged moderate to high. CONCLUSIONS AND RELEVANCE Among nonpregnant adults with subclinical hypothyroidism, the use of thyroid hormone therapy was not associated with improvements in general quality of life or thyroid-related symptoms. These findings do not support the routine use of thyroid hormone therapy in adults with subclinical hypothyroidism.

Abstract
Objective Due to atypical symptom presentation older patients are more prone to delayed sepsis recognition. We investigated whether initial disease severity before emergency department (ED) treatment (including treatable acute organ dysfunction), quality of ED sepsis care and the impact on mortality was different between patients older and younger than 70 years. If differences exist, improvements are needed for ED management of older patients at risk for sepsis. Methods In this observational multicenter study, ED patients who were hospitalized with a suspected infection were stratified by age <70 and ≥70 years. The presence of treatable and potentially reversible acute organ dysfunction was measured by the RO components of the Predisposition, Infection, Response and Organ dysfunction (PIRO) score, reflecting acute sepsis-related organ dysfunction developed before ED presentation. Quality of care, as assessed by the full compliance with nine quality performance measures and the standardized mortality ratio (SMR: observed/expected in-hospital mortality), was compared between older and younger patients. Results The RO-components of the PIRO score were 8 (interquartile range; 4–9) in the 833 older patients, twice as high as the 4 (2–8; P<0.001) in the 1537 younger patients. However, full compliance with all nine quality performance measures was achieved in 34.2 (31.0–37.4)% of the older patients, not higher than the 33.0 (30.7–35.4)% in younger patients (P = 0.640). In-hospital mortality was 9.2% (95%-CI, 7.3–11.2) in patients ≥70, twice as high as the 4.6% (3.6–5.6) in patients <70 years, resulting in an SMR (in study period) of ~0.7 in both groups (P>0.05). Conclusion Older sepsis patients are sicker at ED presentation but are not treated more expediently or reliably despite their extra acuity The presence of twice as much treatable acute organ dysfunction before ED treatment suggests that acute organ dysfunction is recognized relatively late by general practitioners or patients in the out of hospital setting.

Abstract
BACKGROUND Subclinical hypothyroidism (SCH) is a common condition in elderly people, defined as elevated serum thyroid-stimulating hormone (TSH) with normal circulating free thyroxine (fT4). Evidence is lacking about the effect of thyroid hormone treatment. We describe the protocol of a large randomised controlled trial (RCT) of Levothyroxine treatment for SCH. METHODS Participants are community-dwelling subjects aged ≥65 years with SCH, diagnosed by elevated TSH levels (≥4.6 and ≤19.9 mU/L) on a minimum of two measures ≥ three months apart, with fT4 levels within laboratory reference range. The study is a randomised double-blind placebo-controlled parallel group trial, starting with levothyroxine 50 micrograms daily (25 micrograms in subjects <50Kg body weight or known coronary heart disease) with titration of dose in the active treatment group according to TSH level, and a mock titration in the placebo group. The primary outcomes are changes in two domains (hypothyroid symptoms and fatigue / vitality) on the thyroid-related quality of life questionnaire (ThyPRO) at one year. The study has 80% power (at p = 0.025, 2-tailed) to detect a change with levothyroxine treatment of 3.0% on the hypothyroid scale and 4.1% on the fatigue / vitality scale with a total target sample size of 750 patients. Secondary outcomes include general health-related quality of life (EuroQol), fatal and non-fatal cardiovascular events, handgrip strength, executive cognitive function (Letter Digit Coding Test), basic and instrumental activities of daily living, haemoglobin, blood pressure, weight, body mass index and waist circumference. Patients are monitored for specific adverse events of interest including incident atrial fibrillation, heart failure and bone fracture. DISCUSSION This large multicentre RCT of levothyroxine treatment of subclinical hypothyroidism is powered to detect clinically relevant change in symptoms / quality of life and is likely to be highly influential in guiding treatment of this common condition.

Abstract
PURPOSE: Various lines of evidence suggest that proinflammatory factors may play a role in tumor growth and metastasis, the leading cause of cancer-related mortality. However, most evidence originates from animal models, only few human studies reported an association between proinflammatory cytokines and death from cancer. Here, we investigated the association between circulating levels and innate production capacity of proinflammatory cytokines and cancer incidence and mortality in the PROspective Study on Pravastatin in the Elderly at Risk (PROSPER). EXPERIMENTAL DESIGN: Circulating levels of interleukin 6 (IL-6) and C-reactive protein were measured in all 5,804 participants of the PROSPER study. The innate production capacity of IL-6, IL-1beta, and tumor necrosis factor alpha (TNF-alpha) were measured in a random sample of 403 subjects. RESULTS: We showed that high circulating inflammatory markers were associated with an increased risk for cancer incidence and death from cancer during follow-up (all P < 0.05). Moreover, high innate proinflammatory cytokine production capacity is associated with an increased risk for death from cancer (all P < 0.04) but not with higher cancer incidence during follow-up (all P > 0.6). CONCLUSIONS: High innate production capacity of proinflammatory cytokines is associated with an increased risk for death from cancer, probably because of increased tumor growth and metastasis. Because there was no association between innate production capacity and cancer incidence, the association between circulating levels and cancer incidence at least partially reflects reversed causality.
