Show moreObjectives: Urinary tract infection (UTI) is common among older women. However, diagnosis is challenging because of frequent chronic lower urinary tract symptoms, cognitive impairment, and a high prevalence of asymptomatic bacteriuria (ASB). Current urine diagnostics lack specificity, leading to unnecessary treatment and antimicrobial resistance. This study aimed to evaluate the diagnostic accuracy of 12 urine biomarkers for diagnosing UTI in older women. Methods: In this case -control study, cases were women >= 65 years with >= 2 new -onset lower urinary tract symptoms, pyuria, and one uropathogen >= 104 CFU/mL. Controls were asymptomatic and classified as ASB (one uropathogen >= 105 CFU/mL), negative culture, or mixed flora. Urine biomarker concentrations were measured through liquid chromatography -mass spectrometry and ELISA. Diagnostic accuracy parameters of individual biomarkers and a biomarker model were derived from receiver operating characteristic curves. Results: We included 162 community -dwelling and institutionalized older women. Five urine inflam- matory biomarkers demonstrated high discriminative ability (area under the curve >= 0.80): interleukin 6, azurocidin, neutrophil gelatinase-associated lipocalin, tissue inhibitor of metalloproteinases 2, and C -X-C motif chemokine 9. Azurocidin exhibited the highest diagnostic accuracy (sensitivity 86% [95% CI 75% -93%] and specificity 89% [95% CI 82%-94%] at 16.7 ng/mmol creatinine). A combined biomarker and pyuria model showed improved diagnostic accuracy in patients with UTI and ASB, compared with pyuria alone. Discussion: We identified several urine biomarkers that accurately differentiated older women with UTI from asymptomatic women, including ASB. These findings represent a potential advancement towards improved diagnostics for UTI in older women and warrant validation in a diverse population. Manu P.

Show moreBackgroundThe broad concept of health as “the ability to adapt and self-manage in the face of social, physical and emotional challenges” has been operationalized by “Positive Health,” a framework increasingly used in the Netherlands. We explored to what degree the impact of the COVID-19 pandemic and preventive measures on Positive Health differed between community-dwelling older adults without, with mild and with complex health problems, as well as differences flowing from their use of preventive measures.MethodsDuring the second wave in the Netherlands (November 2020–February 2021), a convenience sample of adults aged ≥65 years completed an online questionnaire. Positive Health impact was measured based on self-reported change of current health status, across six dimensions, compared to before the pandemic (decreased/unchanged/increased). The complexity of health problems (past month) was assessed using the validated ISCOPE tool, comparing subgroups without, with mild or with complex health problems. High use of preventive measures was defined as ≥9 of 13 measures and compared to low use (<9 measures).ResultsOf the 2397 participants (median age 71 years, 60% female, and 4% previous COVID-19 infection), 31% experienced no health problems, 55% mild health problems, and 15% complex health problems. Overall, participants reported a median decrease in one Positive Health dimension (IQR 1–3), most commonly in social participation (68%). With an increasing complexity of health problems, subjective Positive Health declined more often across all six dimensions, ranging from 3.3% to 57% in those without, from 22% to 72% in those with mild, and from 47% to 75% in those with complex health problems (p-values for trend <0.001; independent of age and sex). High users of preventive measures more often experienced declined social participation (72% vs. 62%, p < 0.001) and a declined quality of life (36% vs. 30%, p = 0.007) than low users, especially those with complex health problems.ConclusionAs the complexity of health problems increased, the adverse impact of the COVID-19 pandemic and related preventive measures was experienced more frequently across all dimensions of Positive Health. Acknowledging this heterogeneity is pivotal to the effective targeting of prevention and healthcare to those most in need. Show less

Show moreObjectivesDelirium is a serious condition, which poses treatment challenges during hospitalisation for COVID-19. Improvements in testing, vaccination and treatment might have changed patient characteristics and outcomes through the pandemic. We evaluated whether the prevalence and risk factors for delirium, and the association of delirium with in-hospital mortality changed through the pandemic.MethodsThis study was part of the COVID-OLD study in 19 Dutch hospitals including patients ≥70 years in the first (spring 2020), second (autumn 2020) and third wave (autumn 2021). Multivariable logistic regression models were used to study risk factors for delirium, and in-hospital mortality. Differences in effect sizes between waves were studied by including interaction terms between wave and risk factor in logistic regression models.Results1540, 884 and 370 patients were included in the first, second and third wave, respectively. Prevalence of delirium in the third wave (12.7%) was significantly lower compared to the first (22.5%) and second wave (23.5%). In multivariable-adjusted analyses, pre-existing memory problems was a consistent risk factor for delirium across waves. Previous delirium was a risk factor for delirium in the first wave (OR 4.02), but not in the second (OR 1.61) and third wave (OR 2.59, p-value interaction-term 0.028). In multivariable-adjusted analyses, delirium was not associated with in-hospital mortality in all waves.ConclusionDelirium prevalence declined in the third wave, which might be the result of vaccination and improved treatment strategies. Risk factors for delirium remained consistent across waves, although some attenuation was seen in the second wave. Show less

Show moreImportance Although older patients are at increased risk of developing grade 3 or higher chemotherapy-related toxic effects, no studies, to our knowledge, have focused on the association between toxic effects and quality of life (QOL) and physical functioning.Objective To investigate the association between grade 3 or higher chemotherapy-related toxic effects and QOL and physical functioning over time in older patients.Design, Setting, and Participants In this prospective, multicenter cohort study, patients aged 70 years or older who were scheduled to receive chemotherapy with curative or palliative intent and a geriatric assessment were included. Patients were treated with chemotherapy between December 2015 and December 2021. Quality of life and physical functioning were analyzed at baseline and after 6 months and 12 months.Exposures Common Terminology Criteria for Adverse Events grade 3 or higher chemotherapy-related toxic effects.Main Outcomes and Measures The main outcome was a composite end point, defined as a decline in QOL and/or physical functioning or mortality at 6 months and 12 months after chemotherapy initiation. Associations between toxic effects and the composite end point were analyzed with multivariable logistic regression models.Results Of the 276 patients, the median age was 74 years (IQR, 72-77 years), 177 (64%) were male, 196 (71%) received chemotherapy with curative intent, and 157 (57%) had gastrointestinal cancers. Among the total patients, 145 (53%) had deficits in 2 or more of the 4 domains of the geriatric assessment and were classified as frail. Grade 3 or higher toxic effects were observed in 94 patients (65%) with frailty and 66 (50%) of those without frailty (P = .01). Decline in QOL and/or physical functioning or death was observed in 76% of patients with frailty and in 64% to 68% of those without frailty. Among patients with frailty, grade 3 or higher toxic effects were associated with the composite end point at 6 months (odds ratio [OR], 2.62; 95% CI, 1.14-6.05) but not at 12 months (OR, 1.09; 95% CI, 0.45-2.64) and were associated with mortality at 12 months (OR, 3.54; 95% CI, 1.50-8.33). Toxic effects were not associated with the composite end point in patients without frailty (6 months: OR, 0.76; 95% CI, 0.36-1.64; 12 months: OR, 1.06; 95% CI, 0.46-2.43).Conclusions and Relevance In this prospective cohort study of 276 patients aged 70 or older who were treated with chemotherapy, patients with frailty had more grade 3 or higher toxic effects than those without frailty, and the occurrence of toxic effects was associated with a decline in QOL and/or physical functioning or mortality after 1 year. Toxic effects were not associated with poor outcomes in patients without frailty. Pretreatment frailty screening and individualized treatment adaptions could prevent a treatment-related decline of remaining health. Show less

Show moreBackground and AimsOur goals were to study frailty screening in association with hospitalization and decline in quality of life [QoL] and functional status in older patients with inflammatory bowel diseases [IBD].MethodsThis was a prospective multicentre cohort study in IBD patients ≥65 years old using frailty screening [G8 Questionnaire]. Outcomes were all-cause, acute, and IBD-related hospitalization, any infection, any malignancy, QoL [EQ5D-3L], and functional decline (Instrumental Activities of Daily Living [IADL]) during 18 months of follow-up. Confounders were age, IBD type, biochemical disease activity [C-reactive protein ≥10 mg/L and/or faecal calprotectin ≥250 µg/g], and comorbidity [Charlson Comorbidity Index].ResultsOf 405 patients, with a median age of 70 years, 196 [48%] were screened as being at risk for frailty. All-cause hospitalizations occurred 136 times in 96 patients [23.7%], and acute hospitalizations 103 times in 74 patients [18.3%]. Risk of frailty was not associated with all-cause (adjusted hazard ratio [aHR] 1.5, 95% confidence interval [CI] 0.9–2.4), but was associated with acute hospitalizations [aHR 2.2, 95% CI 1.3–3.8]. Infections occurred in 86 patients [21.2%] and these were not associated with frailty. A decline in QoL was experienced by 108 [30.6%] patients, and a decline in functional status by 46 patients [13.3%]. Frailty screening was associated with a decline in QoL (adjusted odds ratio [aOR] 2.1, 95% CI 1.3–3.6) and functional status [aOR 3.7, 95% CI 1.7–8.1].ConclusionsFrailty screening is associated with worse health outcomes in older patients with IBD. Further studies are needed to assess the feasibility and effectiveness of its implementation in routine care. Show less

Show moreContextWith age, the prevalence of subclinical hypothyroidism rises. However, incidence and determinants of spontaneous normalization remain largely unknown.ObjectiveTo investigate incidence and determinants of spontaneous normalization of TSH levels in older adults with subclinical hypothyroidism.DesignPooled data were used from the (1) pretrial population and (2) in-trial placebo group from 2 randomized, double-blind, placebo-controlled trials (Thyroid Hormone Replacement for Untreated Older Adults With Subclinical Hypothyroidism Trial and Institute for Evidence-Based Medicine in Old Age thyroid 80-plus thyroid trial).SettingCommunity-dwelling 65+ adults with subclinical hypothyroidism from the Netherlands, Switzerland, Ireland, and the United Kingdom.ParticipantsThe pretrial population (N = 2335) consisted of older adults with biochemical subclinical hypothyroidism, defined as ≥1 elevated TSH measurement (≥4.60 mIU/L) and a free T4 within the laboratory-specific reference range. Individuals with persistent subclinical hypothyroidism, defined as ≥2 elevated TSH measurements ≥3 months apart, were randomized to levothyroxine/placebo, of which the in-trial placebo group (N = 361) was included.Main Outcome MeasuresIncidence of spontaneous normalization of TSH levels and associations between participant characteristics and normalization.ResultsIn the pretrial phase, TSH levels normalized in 60.8% of participants in a median follow-up of 1 year. In the in-trial phase, levels normalized in 39.9% of participants after 1 year of follow-up. Younger age, female sex, lower initial TSH level, higher initial free T4 level, absence of thyroid peroxidase antibodies, and a follow-up measurement in summer were independent determinants for normalization.ConclusionBecause TSH levels spontaneously normalized in a large proportion of older adults with subclinical hypothyroidism (also after confirmation by repeat measurement), a third measurement may be recommended before considering treatment.

Show moreBackground and aims: Mendelian randomization confirmed multiple risk factors for primary events of coronary artery disease (CAD), but no such studies have been performed on recurrent major coronary events despite interesting insights derived from other designs. We examined the associations between genetically-influenced classical cardiovascular risk factors and the risk of recurrent major coronary events in a cohort of CAD patients. Methods: We included all first-time CAD cases (defined as angina pectoris, chronic ischemic heart disease or acute myocardial infarction) of European ancestry from the UK Biobank. Cases were followed till the end of follow-up, death or when they developed a recurrent major coronary event (chronic ischemic heart disease or acute myocardial infarction). Standardized weighted genetic risk scores were calculated for body mass index (BMI), systolic blood pressure, LDL cholesterol and triglycerides. Results: From a total of 22,949 CAD patients (mean age at first diagnosis 59.8 (SD 7.3) years, 71.1% men), 12,539 (54.6%) reported a recurrent major coronary event within a period of maximum 17.8 years. One standard de-viation higher genetically-determined LDL cholesterol was associated with a higher risk of a recurrent major coronary event (odds ratio: 1.08 [95% confidence interval: 1.05, 1.11]). No associations were observed for genetically-influenced BMI (1.00 [0.98, 1.03]), systolic blood pressure (1.01 [0.98, 1.03]) and triglycerides (1.02 [0.995, 1.05]). Conclusions: Despite the use risk-reducing medications following a first coronary event, this study provided ge-netic evidence that, of the classical risk factors, mainly high LDL cholesterol was associated with a higher risk of developing recurrent major coronary events.

Show moreThe number of older individuals that live independently at home is rising. These older individuals often rely on caregivers who have a similar age and health status. Therefore, caregivers may experience a high burden. We determined the prevalence and associating factors of burden among caregivers of older patients in the emergency department (ED). A cross-sectional study of primary caregivers of patients aged & GE; 70 years visiting the ED of a Dutch teaching hospital was performed. Structured interviews were conducted with patients and their caregivers. Caregiver burden was measured using the caregiver strain index (CSI). Additionally, data from questionnaires and medical records were extracted to determine potential associating factors. Univariate and multivariate regression analyses were conducted to identify independent determinants for burden. Seventy-eight caregivers (39%) experienced a high burden. Multivariate analysis showed a significant association between high caregiver burden and patients with cognitive impairment or dependency for instrumental activities of daily living (IADL) and more self-reported hours of care per day. Almost 40% of older patients in the ED have a caregiver who experiences a high burden. Formal assessment in the ED may help provide adequate care to the patients and their caregivers. Show less

Show moreBackgroundDialysis might not benefit all older patients with kidney failure, particularly those with multimorbid conditions and frailty. Patients' and healthcare professionals' awareness of the presence of geriatric impairments could improve outcomes by tailoring treatment plans and decisions for individual patients. ObjectiveWe aimed to explore the perspectives of patients and healthcare professionals on nephrology-tailored geriatric assessment to fuel decision-making for treatment choices in older patients with kidney failure. DesignIn an exploratory qualitative study using focus groups, participants discussed perspectives on the use and value of nephrology-tailored geriatric assessment for the decision-making process to start or forego dialysis. Participants and MeasurementsPatients (n = 18) with kidney failure, caregivers (n = 4), and professionals (n = 25) were purposively sampled from 10 hospitals. Interviews were audio-recorded, transcribed verbatim and inductively analysed using thematic analysis. ResultsThree main themes emerged that supported or impeded decision-making in kidney failure: (1) patient psycho-social situation; (2) patient-related factors on modality choice; (3) organisation of health care. Patients reported feeling vulnerable due to multiple chronic conditions, old age, experienced losses in life and their willingness to trade longevity for quality of life. Professionals recognised the added value of nephrology-tailored geriatric assessment in three major themes: (i) facilitating continual holistic assessment, (ii) filling the knowledge gap, and (iii) uncovering important patient characteristics. Conclusionsnephrology-tailored geriatric assessment was perceived as a valuable tool to identify geriatric impairments in older patients with kidney failure. Integration of its outcomes can facilitate a more holistic approach to inform choices and decisions about kidney replacement therapy. Show less

Show moreBackground Many older persons use the thyroid hormone levothyroxine which is often continued for life. Scientifically, there is much uncertainty whether simple continuation is the optimal approach. First, the physical need for levothyroxine can decrease with age thereby posing a higher risk of overtreatment and adverse effects. Second, large trials in subclinical hypothyroidism have shown no benefit for the use of levothyroxine. Interestingly, guidelines do not address re-evaluation of the indication. This self-controlled trial aims to determine the effects of discontinuation of levothyroxine treatment in older adults.Methods and analysis Participants are community-dwelling subjects aged ≥60 years using levothyroxine continuously at a stable dosage of ≤150 µg and a level of thyroid-stimulating hormone (TSH) <10 mU/L. After a control period of 12 weeks, levothyroxine treatment is discontinued gradually using a stepwise approach with regular monitoring of thyroid function guided by their GP. The primary outcome is the proportion of participants withdrawn from levothyroxine while maintaining a free T4 level within the reference range and a TSH level <10 mU/L, 52 weeks after the start of discontinuation. Secondary outcomes are compared with the control period (self-controlled) and include among others, the effects on thyroid-specific and general health-related quality of life. Furthermore, patients’ attitudes towards deprescribing and regret regarding discontinuing levothyroxine treatment will be recorded. A total of 513 participants will be recruited to estimate the expected proportion of 50% with a 95% CI ranging from 45% to 55%.Ethics and dissemination Approval was obtained from the institutional Medical Ethics Committee. The Older People Advisory Board Health and Well-being has reviewed the research proposal and their comments were used for improvement. In line with the funding policies of the grant organisation funding this study, the study results will be proactively disseminated to the general public and key public health stakeholders. Show less

Show moreIntroduction: Studies investigating the long-term effects of breast cancer treatment on cognition in older women with breast cancer are lacking, even though preserving cognition is highly valued by the older population. Specifically, concerns have been raised regarding the detrimental effects of endocrine therapy (ET) on cognition. Therefore, we investigated cogni-tive functioning over time and predictors for cognitive decline in older women treated for early breast cancer.Methods: We prospectively enrolled Dutch women aged >70 years with stage I-III breast can-cer in the observational CLIMB study. The Mini-Mental State Examination (MMSE) was performed before ET initiation and after 9, 15 and 27 months. Longitudinal MMSE scores were analysed and stratified for ET. Linear mixed models were used to identify possible pre-dictors of cognitive decline.Results: Among the 273 participants, the mean age was 76 years (standard deviation 5), and 48% received ET. The mean baseline MMSE score was 28.2 (standard deviation 1.9). Cogni-tion did not decline to clinically meaningful differences, irrespective of ET. MMSE scores of women with pre-treatment cognitive impairments slightly improved over time (significant interaction terms) in the entire cohort and in women receiving ET. High age, low educational level and impaired mobility were independently associated with declining MMSE scores over time, although the declines were not clinically meaningful.Conclusion: Cognition of older women with early breast cancer did not decline in the first two years after treatment initiation, irrespective of ET. Our findings suggest that the fear of declining cognition does not justify the de-escalation of breast cancer treatment in older women. 2023 The Authors. Published by Elsevier Ltd.

Show moreBackground: Pre-existing lower urinary tract symptoms (LUTS), cognitive impairment, and the high prevalence of asymptomatic bacteriuria (ASB) complicate the diagnosis of urinary tract infection (UTI) in older women. The presence of pyuria remains the cornerstone of UTI diagnosis. However, > 90% of ASB patients have pyuria, prompting unnecessary treatment. We quantified pyuria by automated microscopy and flowcytometry to determine the diagnostic accuracy for UTI and to derive pyuria thresholds for UTI in older women. Methods: Women >= 65 years with >= 2 new-onset LUTS and 1 uropathogen >= 10(4) colony-forming units (CFU)/mL were included in the UTI group. Controls were asymptomatic and classified as ASB (1 uropathogen >= 10(5) CFU/mL), negative culture, or mixed flora. Patients with an indwelling catheter or antimicrobial pretreatment were excluded. Leukocyte medians were compared and sensitivity-specificity pairs were derived from a receiver operating characteristic curve. Results: We included 164 participants. UTI patients had higher median urinary leukocytes compared with control patients (microscopy: 900 vs 26 leukocytes/mu L; flowcytometry: 1575 vs 23 leukocytes/mu L; P < .001). Area under the curve was 0.93 for both methods. At a cutoff of 264 leukocytes/mu L, sensitivity and specificity of microscopy were 88% (positive and negative likelihood ratio: 7.2 and 0.1, respectively). The commonly used cutoff of 10 leukocytes/mu L had a poor specificity (36%) and a sensitivity of 100%. Conclusions: The degree of pyuria can help to distinguish UTI in older women from ASB and asymptomatic controls with pyuria. Current pyuria cutoffs are too low and promote inappropriate UTI diagnosis in older women. Show less

Show morePurposeOlder patients with COVID-19 can present with atypical complaints, such as falls or delirium. In other diseases, such an atypical presentation is associated with worse clinical outcomes. However, it is not known whether this extends to COVID-19. We aimed to study the association between atypical presentation of COVID-19, frailty and adverse outcomes, as well as the incidence of atypical presentation.MethodsWe conducted a retrospective observational multi-center cohort study in eight hospitals in the Netherlands. We included patients aged >= 70 years hospitalized with COVID-19 between February 2020 until May 2020. Atypical presentation of COVID-19 was defined as presentation without fever, cough and/or dyspnea. We collected data concerning symptoms on admission, demographics and frailty parameters [e.g., Charlson Comorbidity Index (CCI) and Clinical Frailty Scale (CFS)]. Outcome data included Intensive Care Unit (ICU) admission, discharge destination and 30-day mortality.ResultsWe included 780 patients, 9.5% (n = 74) of those patients had an atypical presentation. Patients with an atypical presentation were older (80 years, IQR 76-86 years; versus 79 years, IQR 74-84, p = 0.044) and were more often classified as severely frail (CFS 6-9) compared to patients with a typical presentation (47.6% vs 28.7%, p = 0.004). Overall, there was no significant difference in 30-day mortality between the two groups in univariate analysis (32.4% vs 41.5%; p = 0.173) or in multivariate analysis [OR 0.59 (95% CI 0.34-1.0); p = 0.058].ConclusionsIn this study, patients with an atypical presentation of COVID-19 were more frail compared to patients with a typical presentation. Contrary to our expectations, an atypical presentation was not associated with worse outcomes.Key Summary PointsAimTo study the association between atypical presentation of COVID-19, frailty and adverse outcomes, as well as the incidence of atypical presentation.FindingsIn this study, an atypical presentation of COVID-19 was significantly associated with frailty. However, patients with an atypical presentation of COVID-19 did not have worse disease outcomes.MessagePhysicians need to remain alert for COVID-19 in frail older patients, as they may present without typical complaints.

Show moreIntroduction: Vulvar cancer is a disease that mainly affects older women. Frailty is an important predictor of outcomes and geriatric assessment can help tailor treatment decisions and improve outcomes. This study aims to assess the prevalence of frailty in older women with vulvar cancer, and how it relates to integrated geriatric care and treatment according to the oncological guidelines. Materials and Methods: A single-center cohort study was performed, among patients 70 years and older, who were diagnosed with vulvar cancer at Leiden University Medical Center, between January 2012 and May 2020. Data on geriatric assessment, treatment decision-making and treatment-related outcomes were collected. Results: Our study included 114 patients. Mean age was 79.7 years, and 52 patients (45.6%) were frail. Of the frail patients, 42.0% were referred to a geriatrician. In eight of these cases, the geriatrician was actively involved in weighing the benefit and harm of standard oncological treatment versus de-escalated treatment. Frailty, higher age, impairment in the somatic domain, cognitive impairment, and functional dependency were associated with referral to a geriatrician and with active involvement of a geriatrician in decision making. In 26 of frail patients (50.0%) oncological treatment was de-escalated. Frailty, higher age, impairment in the somatic domain, cognitive impairment, and functional dependency were associated with de-escalation of treatment. De-escalated treatment did not compromise survival. Discussion: Frailty is prevalent among older women with vulvar cancer and is associated with referral to a geriatrician and de-escalation of oncological treatment. While this reflects that it is deemed important to tailor treatment decision for frail patients, most frail patients are not routinely evaluated by a geriatrician. Further multidisciplinary collaboration and research is necessary to optimize tailored treatment decisions for this patient group. Show less

Show moreNew treatment strategies have improved survival of metastatic colorectal cancer in trials. However, it is not clear whether older patients benefit from these novel therapies, as they are often not included in pivotal trials. Therefore, we investigated treatment patterns and overall survival over time in older patients with metastatic colorectal cancer in a population-based study. We identified 22.192 Dutch patients aged & GE;70 years diagnosed with synchronous metastatic colorectal cancer between 2005 and 2020 from the Netherlands Cancer Registry. Changes in treatment over time were assessed with logistic regression models. Survival was assessed by Cox proportional hazard ratios (HR). Results showed that chemotherapy use increased between 2005 and 2015, but declined from 2015 onwards, while more patients received best supportive care. Over time, fewer patients underwent primary tumor resection alone. Although survival of both metastatic colon and rectal cancer improved until 2014, survival of colon cancer decreased from 2014 onwards (HR 1.04, 95% confidence interval [CI] 1.01-1.05), which was seen in all age groups. Survival of metastatic rectal cancer patients remained unchanged from 2014 onwards (HR 1.00, 95% CI 0.98-1.03) in all age groups. In conclusion, treatment patterns of Dutch older patients with synchronous metastatic colorectal cancer rapidly changed from 2005 to 2020, with increasing percentages of patients receiving best supportive care. Survival of metastatic colon cancer decreased from 2014 onwards. The implementation of a colorectal cancer screening program and patient selection might explain why only a subset of older patients seem to benefit from the availability of novel treatment options.

Although survival of both metastatic colon and rectal cancer improved until 2014, survival of colon cancer decreased from 2014 onwards (HR 1.04, 95% confidence interval [CI] 1.01-1.05), which was seen in all age groups. Survival of metastatic rectal cancer patients remained unchanged from 2014 onwards (HR 1.00, 95% CI 0.98-1.03) in all age groups. In conclusion, treatment patterns of Dutch older patients with synchronous metastatic colorectal cancer rapidly changed from 2005 to 2020, with increasing percentages of patients receiving best supportive care. Survival of metastatic colon cancer decreased from 2014 onwards. The implementation of a colorectal cancer screening program and patient selection might explain why only a subset of older patients seem to benefit from the availability of novel treatment options.

Show moreObjective to investigate the association between variability and loss of body weight with subsequent cognitive performance and activities of daily living in older individuals. Design cross-sectional cohort study. Setting PROspective Study of Pravastatin in the Elderly at Risk, multicentre trial with participants from Scotland, Ireland and the Netherlands. Subjects 4,309 participants without severe cognitive dysfunction (mean age 75.1 years, standard deviation (SD) = 3.3), at higher risk for cardiovascular disease (CVD). Methods body weight was measured every 3 months for 2.5 years. Weight loss was defined as an average slope across all weight measurements and as >= 5% decrease in baseline body weight during follow-up. Visit-to-visit variability was defined as the SD of weight measurements (kg) between visits. Four tests of cognitive function were examined: Stroop test, letter-digit coding test (LDCT), immediate and delayed picture-word learning tests. Two measures of daily living activities: Barthel Index (BI) and instrumental activities of daily living (IADL). All tests were examined at month 30. Results both larger body weight variability and loss of >= 5% of baseline weight were independently associated with worse scores on all cognitive tests, but minimally with BI and IADL. Compared with participants with stable weight, participants with significant weight loss performed 5.83 seconds (95% CI 3.74; 7.92) slower on the Stroop test, coded 1.72 digits less (95% CI -2.21; -1.13) on the LDCT and remembered 0.71 pictures less (95% CI -0.93; -0.48) on the delayed picture-word learning test. Conclusion in older people at higher risk for CVD, weight loss and variability are independent risk-factors for worse cognitive function. Show less

Show moreObjectives: Previous findings suggest a vascular foundation underlying apathy, but transdiagnostic and prospective evidence on vascular apathy is scarce. This study examines the association between vascular disease and the presence and development of apathy symptoms in the very old.Methods: Four cohorts of the Towards Understanding Longitudinal International older People Studies (TULIPS)-consortium were included in a two-staged, individual participant data meta-analysis using generalized linear mixed models, Vascular disease was defined as a history of any clinical atherosclerotic pathology (angina pectoris, myocardial infarction, intermittent claudication, transient ischemic attack, stroke or related surgeries) and was related to apathy symptoms as repeatedly measured by the Geriatric Depression Scale (GDS-3A >= 2) over a maximum of 5 years.Results: Of all 1868 participants (median age 85 years old), 53.9% had vascular disease and 44.3% experienced apathy symptoms. Participants with vascular disease had a 76% higher risk of apathy symptoms at baseline (odds ratio (OR) 1.76, 95% confidence interval (CI) 1.32-2.35), irrespective of depressive symptoms and only partially explained by stroke. Conversely, there was no association of vascular disease with the occurrence of apathy symptoms longitudinally, both in those with apathy at baseline (OR 1.00, 95% CI 0.84-1.20) and without (OR 0.96, 95% CI 0.841.09).Conclusions: Vascular disease in the very old is associated with apathy symptoms cross-sectionally, but not proven longitudinally, independent of depressive symptoms. These findings query a vascular cause underlying apathy symptoms. However, the consistency of our cross-sectional findings in direction and magnitude across the TULIPS-consortium do emphasize international relevance of the interplay of vascular factors and apathy in advanced age, which meaning needs further unravelling.

Show moreThe response to lifestyle intervention studies is often heterogeneous, especially in older adults. Subtle responses that may represent a health gain for individuals are not always detected by classical health variables, stressing the need for novel biomarkers that detect intermediate changes in metabolic, inflammatory, and immunity-related health. Here, our aim was to develop and validate a molecular multivariate biomarker maximally sensitive to the individual effect of a lifestyle intervention; the Personalized Lifestyle Intervention Status (PLIS). We used H-1-NMR fasting blood metabolite measurements from before and after the 13-week combined physical and nutritional Growing Old TOgether (GOTO) lifestyle intervention study in combination with a fivefold cross-validation and a bootstrapping method to train a separate PLIS score for men and women. The PLIS scores consisted of 14 and four metabolites for females and males, respectively. Performance of the PLIS score in tracking health gain was illustrated by association of the sex-specific PLIS scores with several classical metabolic health markers, such as BMI, trunk fat%, fasting HDL cholesterol, and fasting insulin, the primary outcome of the GOTO study. We also showed that the baseline PLIS score indicated which participants respond positively to the intervention. Finally, we explored PLIS in an independent physical activity lifestyle intervention study, showing similar, albeit remarkably weaker, associations of PLIS with classical metabolic health markers. To conclude, we found that the sex-specific PLIS score was able to track the individual short-term metabolic health gain of the GOTO lifestyle intervention study. The methodology used to train the PLIS score potentially provides a useful instrument to track personal responses and predict the participant's health benefit in lifestyle interventions similar to the GOTO study.

Show moreSimple Summary Immunotherapy has strongly improved outcomes of patients with metastatic melanoma in recent years, but previous studies have shown that survival of older patients often lacks behind. In this study, we investigated treatment prescription of immunotherapy over time in relation to age and survival. We showed that overall survival has improved in patients with synchronous metastasised melanoma aged <75 years, but not in patients aged 75 years or older. This might be explained by lower prescription rates of immunotherapy in this age group. Around 45% of patients with melanoma are older than 65 years. In recent years, immunotherapy has proven very effective for metastasised melanoma. The aim of this study was to investigate the time trends in treatment strategies and survival in older versus younger patients with synchronous metastasised melanoma. We included all patients diagnosed between 2000 and 2019 from the Netherlands cancer registry. We analysed changes in first-line systemic treatment using multivariable logistic regression models, stratified by age (<65, 65-75, and >= 75). Changes in overall survival were studied using multivariable Cox regression analysis. A total of 2967 patients were included. Immunotherapy prescription increased significantly over time for all age groups (<65 years: 11.8% to 64.9%, p < 0.001; 65-75 years: 0% to 68.6%, p < 0.001; >75 years: 0% to 39.5%, p < 0.001). In multivariable analyses, overall survival improved for patients aged <65 and 65-75 (HR 0.96, 95% CI 0.92-1.00 and HR 0.95, 95% CI 0.89-1.00, respectively), but not in patients over 75 (HR 0.98, 95% CI 0.91-1.05). In conclusion, overall survival has improved in patients with synchronous metastasised melanoma aged <75 years, but not in patients aged 75 years or older. This might be explained by lower prescription rates of immunotherapy in this age group. Show less
