Show moreBackgroundThe elderly (>= 65years) are one of the populations most at risk for respiratory tract infections (RTIs). The aim of this study was to determine whether nasal and/or oropharyngeal microbiota profiles are associated with age and RTIs.MethodsNasal and oropharyngeal swabs of 152 controls and 152 patients with an RTI were included. The latter group consisted of 72 patients with an upper respiratory tract infection (URTI) and 80 with a lower respiratory tract infection (LRTI). Both nasal and oropharyngeal swabs were subjected to microbiota profiling using amplicon sequencing of the 16S rRNA gene. Moraxella species were determined using quantitative real-time PCR and culture.ResultsBased on the microbiota profiles of the controls and the patients with an RTI, eight nasal and nine oropharyngeal microbiota clusters were defined. Nasal microbiota dominated by either Moraxella catarrhalis or Moraxella nonliquefaciens was significantly more prevalent in elderly compared to mid-aged adults in the control group (p=0.002). Dominance by M. catarrhalis/nonliquefaciens was significantly less prevalent in elderly with an LRTI (p=0.001) compared to controls with similar age.ConclusionsNasal microbiota dominated by M. catarrhalis/nonliquefaciens is associated with respiratory health in the elderly population.

Show moreObjective: To analyze and compare experiences of anxiety and discomfort caused by the Epley maneuver and the willingness for a potential retreatment between younger (<= 70 yr) and older (>70 yr) patients. Study Design: Prospective, observational cohort study. Setting: Tertiary referral center. Methods: Dutch adults, diagnosed with posterior canal benign paroxysmal positional vertigo, were included. Patients with dementia or subjected to an Epley maneuver <= 4 months before the hospital visit were excluded. Patients were asked about their experiences with the Epley maneuver directly after the maneuver, after 2 weeks and after 2 months. Differences in experiences between the age groups were tested with the Fisher's exact test and subgroup analyses were performed using multivariable logistic regression. Results: Out of 179 included patients, 115 (64%) were aged <= 70 and 134 (75%) were female. In both groups, 25% reported anxiety directly after the Epley maneuver. Two weeks later, 19 and 27%, respectively (p = 0.26) reported anxiety. In the young group, 30% expressed discomfort directly after treatment compared with 45% in the elderly (OR 1.98, 95% CI 1.05-3.75, p = 0.04). Two weeks later, this was 36 and 38%, respectively (p = 0.87). This decreased to 24 and 33%, respectively (p = 0.37), after 2 months. There was no significant difference in willingness for potential retreatment between both groups after 2 weeks (93 and 95%, respectively, p = 0.75) nor after 2 months (97 and 92%, respectively, p = 0.13). Conclusion: The Epley maneuver results in little anxiety and discomfort both in young and in elderly patients. Most patients show willingness for potential retreatment in case symptoms recur.

Show moreBackground: Decreased cancer specific survival in older colorectal patients is mainly due to mortality in the first year, emphasizing the importance of the first postoperative year. This study aims to gain an overview and time trends of short-term mortality in octogenarians (>= 80 years) with colorectal cancer across four North European countries.Methods: Patients of 80 years or older, operated for colorectal cancer (stage I-Ill) between 2005 and 2014, were included. Population-based cohorts from Belgium, Denmark, the Netherlands, and Sweden were collected. Separately for colon- and rectal cancer, 30-day, 90-day, one-year, and excess one-year mortality were calculated. Also, short-term mortality over three time periods (2005-2008, 2009-2011, 2012-2014) was analyzed.Results: In total, 35,158 colon cancer patients and 10,144 rectal cancer patients were included. For colon cancer, 90-day mortality rate was highest in Denmark (15%) and lowest in Sweden (8%). For rectal cancer, 90-day mortality rate was highest in Belgium (11%) and lowest in Sweden (7%). One-year excess mortality rate of colon cancer patients decreased from 2005 to 2008 to 2012-2014 for all countries (Belgium: 17%-11%, Denmark: 21%-15%, the Netherlands: 18%-10%, and Sweden: 10%-8%). For rectal cancer, from 2005 to 2008 to 2012-2014 one-year excess mortality rate decreased in the Netherlands from 16% to 7% and Sweden: 8%-2%).Conclusions: Short-term mortality rates were high in octogenarians operated for colorectal cancer. Short-term mortality rates differ across four North European countries, but decreased over time for both colon and rectal cancer patients in all countries. (C) 2019 Published by Elsevier Ltd.

Show morePurpose: To compare health-related quality of life (HRQL) in elderly breast cancer patients between two types of Accelerated Partial Breast Irradiation: intraoperative radiotherapy (IORT) and external beam APBI (EB-APBI).Methods: Between 2011 and 2016 women >= 60 years undergoing breast conserving therapy for early stage breast cancer were included in a prospective multi-centre cohort study. Patients were treated with electron IORT (1 x 23.3 Gy) or photon EB-APBI (10 x 3.85 Gy daily). HRQL was measured by the EORTC-QLQ C30 and BR23 questionnaires before surgery and at several time points until 1 year.Results: HRQoL data was available of 204 IORT and 158 EB-APBI patients. In longitudinal analyses emotional functioning and future perspective were significantly, but not clinically relevantly, worse in IORT-treated patients, and improved significantly during follow-up in both groups. All other aspects of HRQL slightly worsened after treatment and recovered within 3 months with an improvement until 1 year. Cross-sectional analysis showed that postoperatively fatigue and role functioning were significantly worse in IORT patients compared to EB-APBI patients who were not yet irradiated, but the difference was not clinically relevant. At other timepoints there were no significant differences. Multivariable analysis at 1 year identified comorbidity and systemic therapy as risk factors for a worse global health score (GHS).Conclusions: EB-APBI and IORT were well tolerated. Despite a temporary deterioration after treatment, all HRQL scales recovered within 3 months resulting in no clinically relevant differences until 1 year between groups nor compared to baseline levels.

Show moreIn this thesis the risk factors of venous thrombosis will be discussed in the general and particularly the elderly population. The goal of this thesis is to provide insights on risk factors of thrombosis in the elderly population, in order to advance our basic understanding of physiological age-related changes that increase the risk of venous thrombosis and which may ultimately lead to improved personalized interventions. In this chapter firstly background information will be provided on risk factors for venous thrombosis, focussing specifically on age as a risk factor. Secondly, the role of veins and venous valves in the development of venous thrombosis will be discussed and thirdly, global assays as a potential tool to identify patients at high risk for venous thrombosis will be considered. The study populations used in this thesis will discussed, and an outline of this thesis will be provided. Show less

Show moreAs a result of our ageing population, breast cancer is becoming a disease of the elderly. Unfortunately, most studies investigating the efficacy of treatment do not include older patients and are not representative for the older population. In this thesis, we investigated whether there is variation in treatment and survival among older women with breast cancer in five European countries. Moreover, we study the long term efficacy of two types of adjuvant endocrine therapy in postmenopausal women. In addition, the effect of age and comorbidities on breast cancer death in the presence of competing mortality is studied. Finally, we investigate whether other endpoints in clinical studies might be more relevant for the older population and we introduce a new endpoint for clinical research in the older population with cancer.

Show moreOlder women with breast cancer are underrepresented in the available evidence. Therefore, there is no solid evidence on how to treat older women with breast cancer. This thesis has three main conclusions: 1. There are large international differences in the treatment strategy of breast cancer among older women. These differences are not associated with a significant difference in prognosis. 2. The presence of comorbidity has an important impact on the general prognosis of older women with breast cancer. We did not show an important association between specific comorbidities or the use of co-medications and the breast cancer specific prognosis. 3. Concerning older women with breast cancer for research, there are very important methodological issues to take into account, including to avoidance of selection bias and the proper methodologies to take in to account the chance of dying from another cause of cancer: the competing risk of mortality. Future research should be done to create a tool which can assist in identifying the individualised treatment strategy for each older woman with breast cancer. This will have to take into consideration patient’s and tumour’s information, as well as the endpoints for each individual patient. Show less
