Food webs in isolation: The food-web structure of a freshwater reservoir with armoured shores in a former coastal bay area.

Many shallow coastal bays have been closed off from the sea to mitigate the risk of flooding, resulting in coastal reservoir lakes with artificial armoured shorelines. Often these enclosed ecosystems show a persistent decline in biodiversity and ecosystem services, which is likely reflected in their food-web structure. We therefore hypothesize that the food webs of coastal reservoir lakes with armoured shorelines (1) consist of relatively few species with a low food-web connectance and short food chains, and (2) are mainly fuelled by autochthonous organic matter produced in the pelagic zone. To investigate these two hypotheses, we used stable-isotope analysis to determine the food-web structure of lake Markermeer (The Netherlands), a large reservoir lake with armoured shorelines in a former coastal bay area. Contrary to expectation, connectance of the food web in lake Markermeer was comparable to other lakes, while food-chain length was in the higher range. However, the trophic links revealed that numerous macroinvertebrates and fish species in this constructed lake exhibited omnivorous feeding behaviour. Furthermore, in line with our second hypothesis, primary consumers heavily relied on pelagically derived organic matter, while benthic primary production exerted only a minor and seasonal influence on higher trophic levels. Stable-isotope values and the C:N ratio of sediment organic matter in the lake also aligned more closely with phytoplankton than with benthic primary producers. Moreover, terrestrial subsidies of organic matter were virtually absent in lake Markermeer. These findings support the notion that isolation of the lake through shore armouring and the lack of littoral habitats in combination with persistent resuspension of sediments have affected the food web. We argue that restoration initiatives should prioritize the establishment of land-water transition zones, thereby enhancing habitat diversity, benthic primary production, and the inflow of external organic matter while preserving pelagic primary production.

Diagnostic Performance of Screening Tools for Depressive Symptoms in Vulnerable Older Patients with Cancer Undergoing Comprehensive Geriatric Assessment (CGA): Results from the SCREEN Pilot Study.

Depression is a common and disabling disorder in later life, particularly among people with poor physical health. There are many screening tools available that can be used to examine depressive symptoms; however, not all of them may be appropriate or accurate for older adults with cancer. This pilot study was designed to test the diagnostic performance of two screening tools and their short versions in a cohort of vulnerable (G8 score ≤ 14/17) older patients with cancer undergoing comprehensive geriatric assessment (CGA). The prospective analysis covered 50 vulnerable patients with cancer aged ≥70 years. The diagnostic performance of the Geriatric Depression Scale (GDS)-15, GDS-4, Patient Health Questionnaire (PHQ)-9 and PHQ-2 was compared to the 'gold standard' Structured Clinical Interview for DSM-5 Disorders (SCID-5-S) depression module A. The sensitivity and specificity in detecting depressive symptoms were the highest in the case of PHQ-2, with an area under the receiver operating characteristic curve (AUROC) of 92.7%. The AUROC for the 9-item version, PHQ-9, was 90.2%. For the GDS-15 and GDS-4, the AUROC was only 56.2% and 62.0%, respectively. The SCREEN pilot study illustrates the potential benefit of using a shorter screening tool, PHQ-2, to identify older patients with cancer who would benefit from a more in-depth emotional evaluation as part of a CGA.

Developing and evaluating a participatory arts programme for cancer patients and their caregivers.

OBJECTIVES: Cancer patients, survivors and caregivers often encounter severe distress, having significant consequences to wellbeing, functionality and physical health. This study developed and evaluated a participatory arts programme to determine if such could help to improve the wellbeing of cancer patients and their caregivers. METHODS: To inform the development of a participatory arts programme, cancer patients and their caregivers at an Organisation of European Cancer Institute (OECI)-designated cancer centre were asked which activities they would wish to engage in (anonymous survey one). A programme was then developed and trialled for 1 year. Following participation, we explored the satisfaction and any benefits of taking part (anonymous survey two). RESULTS: Survey one had a participation rate of 70%. In this survey, participants indicated they preferred group-based activities (61%) over an individual approachto take place on a monthly basis (46%). The developed programme ran from December 2018 to December 2019, with 435 patients and caregivers taking part. Two hundred and eighteen completed survey two and revealed a positive response to both the structure and content of the programme and its impact on the wellbeing of patients and caregivers. The majority indicated they felt (much) betterfrom participating in the participatory arts programme. CONCLUSION: This study points out the interest and potential value of a participatory arts programme to the perceived wellbeing. This suggests such programmes could be incorporated into cancer care provision, to serve as psychosocial support. The latter is particularly relevant for improving the lives, wellbeing and health of cancer patients and those supporting them.

Pain Medication Adherence in Patients with Cancer: A Pragmatic Review.

OBJECTIVE: Adherence to pain medication in patients with cancer is crucial for successful pain therapy. This review aimed to investigate the rate of adherence, which factors influence adherence, whether adherence differs in diverse patient populations, whether there are methods to improve adherence, and the relationship between adherence and pain relief. METHODS: This review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE/PubMed, Embase, Web of Science, Cochrane, and ClinicalTrials.gov were searched. All types of studies investigating adherence of patients with cancer, factors influencing adherence, and methods to improve adherence to pain medication were included. They were first screened on title and abstract and thereafter on full text. Selected articles were subjected to a quality assessment according to the PRISMA checklist. From included articles, study characteristics and outcomes were extracted. RESULTS: Of 795 articles, 18 were included. Different methods were used to measure adherence, which led to adherence rates ranging from 8.9% to 82.0%. White Americans and men were found to be more adherent than African Americans and women. Because of various barriers, adherence is often suboptimal. Fear of addiction, physiological and harmful effects, tolerance, and disease progression are common concerns. Interventions, such as pain education booklets, pain consults, and specialized nurses, may be beneficial to increase the adherence. Lower adherence rates were associated with lower pain relief. CONCLUSION: Adherence of cancer patients to pain medication is suboptimal. Health care workers should focus on addressing barriers to increase adherence to obtain better pain relief.

Oncologic Home-Hospitalization Delivers a High-Quality and Patient-Centered Alternative to Standard Ambulatory Care: Results of a Randomized-Controlled Equivalence Trial.

PURPOSE: Given the increasing burden of cancer on patients, health care providers, and payers, the shift of certain outpatient procedures to the patients' homes (further indicated as oncologic home-hospitalization [OHH]) might be a high-quality, patient-centered, and cost-effective alternative to standard ambulatory cancer care (SOC). METHODS: A randomized-controlled trial was conducted to evaluate the quality of a locally implemented model for OHH (n = 74) compared with SOC (n = 74). The model for OHH consisted of home administration of certain subcutaneous cancer drugs (full OHH) and home nursing assessments before ambulatory systemic cancer therapy (partial OHH). Quality was evaluated based on patient-reported quality of life (QoL) and related end points; service use and cost data; safety data; patient-reported satisfaction and preferences; and model efficiency. An equivalence design was used for primary end point analysis. Participants were followed during 12 weeks of systemic cancer treatment. RESULTS: This trial demonstrated equivalence of both models (OHH v SOC) in terms of patient-reported QoL (95% CI not exceeding the equivalence margin of 10%). Full OHH resulted in significantly less hospital visits (mean of 5.6 ± 3.0 v 13.2 ± 4.6; P = .011). Partial OHH reduced waiting times for therapy administration at the day care unit with 45% per visit (2 hours 36 minutes ± 1 hour 4 minutes v 4 hours ± 1 hour 4 minutes; P < .001). No safety issues were detected. Of the intervention group, 88% reported to be highly satisfied with the OHH model, and 77% reported a positive impact on their QoL. At study end, 60% of both study arms preferred OHH above SOC. CONCLUSION: The shift of particular procedures from the outpatient clinic to the patients' homes offers a high-quality and patient-centered alternative for a large proportion of patients with cancer. Further research is needed to evaluate potential cost-efficiency.

A randomised wait-list controlled trial to evaluate Emotional Freedom Techniques for self-reported cancer-related cognitive impairment in cancer survivors (EMOTICON).

BACKGROUND: Cancer-related cognitive impairment (CRCI) is a prevalent source of comprised quality of life in cancer survivors. This study evaluated the efficacy of Emotional Freedom Techniques (EFT) on self-reported CRCI (sr-CRCI). METHODS: In this prospective multicentre randomised wait-list controlled study (ClinicalTrials.gov Identifier: NCT02771028), eligible cancer survivors had completed curative treatment, were 18 years or older and screened positive for sr-CRCI with ≥ 43 on the Cognitive Failures Questionnaire (CFQ). Participants were randomised to the immediate treatment group (ITG) or wait-list control (WLC) group, based on age (< or ≥ 65 years), gender, treatment (chemotherapy or not), and centre. The ITG started to apply EFT after inclusion and performed this for 16 weeks. The WLC group could only start the application of EFT after 8 weeks of waiting. Evaluations took place at baseline (T0), 8 weeks (T1) and 16 weeks (T2). The primary outcome was the proportion of patients with sr-CRCI according to the CFQ score. FINDINGS: Between October 2016 and March 2020, 121 patients were recruited with CFQ ≥ 43 indicating sr-CRCI. At T1, the number of patients scoring positive on the CFQ was significantly reduced in the ITG compared to the WLC group (40.8% vs. 87.3% respectively; p<0.01). For the WLC group, a reduction in CFQ scores was observed at T2, comparable to the effect of the ITG at T1. Linear mixed model analyses indicated a statistically significant reduction in the CFQ score, distress, depressive symptoms, fatigue and also an improvement in quality of life. INTERPRETATION: This study provides evidence for the application of EFT for sr-CRCI in cancer survivors and suggests that EFT may be useful for other symptoms in cancer survivors.

Cervical radiculopathy caused by vertebral artery loop formation: a case report.

Vertebral artery loop formation is a rare cause of cervical radiculopathy. We report a case of a 70-year-old man who was referred because of a chronic cervicobrachialgia. Initial plain cervical x-ray showed widening of the left C3-C4 intervertebral foramen. Additional magnetic resonance angiography revealed the presence of a vertebral artery loop, which had migrated into the left C3-C4 neural foramen and caused compression of the left C4 nerve root. Surgery was considered, but the patient's symptoms resolved with conservative treatment. The aim of this case report is to raise the knowledge of both clinicians and radiologists about vertebral artery loop formation as a rare but potentially life-threatening cause of cervical radiculopathy. If overlooked, cerebrovascular stroke during transforaminal cervical steroid injections or catastrophic vertebral artery damage during surgery may occur.

Acupuncture as a Complementary Therapy for Cancer Care: Acceptability and Preferences of Patients and Informal Caregivers.

Background: Acupuncture can effectively manage cancer-related side effects, for both patients undergoing treatment and for cancer survivors. It may also be effective in managing physiological and psychological symptoms common among informal caregivers of cancer patients. Objectives: The aim of this survey was to explore the acceptability and preferences of cancer patients, cancer survivors, and their informal caregivers in relation to acupuncture. Methods: The survey was conducted from 20th November to 27th November 2018. The questionnaire was developed to explore acceptability and preferences, including motivation, symptoms to be addressed, and practical issues (location, cost, etc.), in relation to acupuncture. Results: The survey response rate was 94.5% in cancer patients and cancer survivors and 100% in caregivers. Acceptability of acupuncture was 34.5% (n = 40/116) and 48.0% (n = 26/54) in cancer patients and caregivers, respectively. About 52.5% (n = 21/40) of patients preferred to undergo acupuncture at the day center clinic, whereas caregivers had no specific preference. Patients and cancer survivors would use acupuncture for symptoms of fatigue (60%), listlessness (57.5%), and pain (47.5%). Informal caregivers expressed an interest in using acupuncture for their pain, stress, and sleeping difficulties 48.0% (n = 26/54). Conclusion: Cancer patients, cancer survivors, and informal caregivers would accept acupuncture as a complementary therapy. This openness and preference to acupuncture provide the foundations for this complementary therapy to be incorporated into holistic and supportive cancer care, both for patients and those supporting them.

Effectiveness of Adjunctive Analgesics in Head and Neck Cancer Patients Receiving Curative (Chemo-) Radiotherapy: A Systematic Review.

OBJECTIVE: Our aim was to give an overview of the effectiveness of adjunctive analgesics in head and neck cancer (HNC) patients receiving (chemo-) radiotherapy. DESIGN: Systematic review. INTERVENTIONS: This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Embase, Web of Science, the Cochrane Library, and ClinicalTrials.gov were searched for studies concerning "head neck cancer," "adjunctive analgesics," "pain," and "radiotherapy." OUTCOME MEASURES: Pain outcome, adverse events, and toxicity and other reported outcomes, for example, mucositis, quality of life, depression, etc. RESULTS: Nine studies were included in our synthesis. Most studies were of low quality and had a high risk of bias on several domains of the Cochrane Collaboration tool. Only two studies comprised high-quality randomized controlled trials in which pregabalin and a doxepin rinse showed their effectiveness for the treatment of neuropathic pain and pain from oral mucositis, respectively, in HNC patients receiving (chemo-) radiotherapy. CONCLUSIONS: More high-quality trials are necessary to provide clear evidence on the effectiveness of adjunctive analgesics in the treatment of HNC (chemo-) radiation-induced pain.

Quality of blood samples collected at home does not affect clinical decision making for the administration of systemic cancer treatment.

The aim of this exploratory clinical study was to evaluate whether the preanalytical quality of blood samples subjected to delayed centrifugation and transport - as a result of home-sampling - is affected in a way it alters the clinical decision-making for patients under systemic cancer therapy. This evaluation is part of a comprehensive investigation of the opportunities for oncological home-hospitalization. Forty-nine patients with cancer donated two additional blood samples during their ambulatory hospital visit. Fifteen blood analytes were compared between routine blood samples and samples that were subjected to transport and delayed centrifugation in order to mimic a locally implemented model for oncological home-hospitalisation. Deviations were analysed by means of Deming regression. For those analytes showing statistically significant intercepts and/or slopes, the mean deviations were compared to the desirable analytical bias; and the intra-individual differences were compared with the limits for clinical decision-making. Statistically significant intercepts and/or slopes were observed for haematocrit (HCT), mean cellular volume (MCV), platelets count (PLT) and C-reactive protein (CRP). Differences exceeding the allowable margins of desirable analytical bias were observed for HCT and MCV. Risk of different clinical decision-making couldn't be observed for any of the analytes showing statistically significant differences. These results demonstrate that home-collection of blood samples, transported at room temperature and centrifuged within a mean time of five hours after sampling, has no effect on clinical decision-making with regards to systemic cancer therapy. However, attention should be paid to the potential occurrence of haemolysis during the preanalytical phase, which can negatively influence haemolysis-dependent variables.

Shifting specialized oncological care from hospital- to home-setting: is there support among patients, specialists and general practitioners?

OBJECTIVES: Oncological home-hospitalization (OHH) might be a patient-centred approach to deal with the increasing burden of cancer on health-care facilities and finances. Before implementation into practice, its feasibility, costs and support among stakeholders should be evaluated. The purpose of this trial was to explore patients', specialists' and general practitioners' (GPs) perspectives towards the opportunities of implementing OHH within the Belgian health-care system. METHODS: A regional cross-sectional survey study was launched in order to investigate the stakeholders' views on OHH and the current cancer care focusing on integration of primary care and continuous care. RESULTS: Of the responders, 37 out of 163 patients (23%), 45 of 62 GPs (73%) and 10 of 15 specialists (67%) feel positive about the opportunities for OHH. Nevertheless, 11/15 specialists (73%) and 51/62 GPs (82%) feel primary care might currently be (too) little involved in order to ensure continuous care for cancer patients. Opportunities for improved continuous care are seen in better communication between primary care and hospital, and more patient contacts for primary care during the cancer treatment process. CONCLUSION: The results of this local survey study demonstrated there is support among different stakeholder groups for the implementation of OHH within the Belgian health-care context. However, some barriers impeding transmural continuous care should be tackled before implementing such model into practice. Better communication between health-care professionals and more patients contacts are suggested, and an adjusted legal and financial framework is required.

Underrepresentation of vulnerable older patients with cancer in phase II and III oncology registration trials: A case-control study.

OBJECTIVES: We aimed to determine the proportion of "fit" versus "vulnerable" older patients with cancer included in phase II and III oncology registration trials, as compared to the proportions in a real life oncology setting. METHODS: Trial and patient characteristics of older (≥70years) patients treated at the OECI-designated clinical cancer centre in Kortrijk and included in a phase II or III oncology registration trial were collected retrospectively. These patients were matched individually with randomly-selected patients from the general oncology setting, based on gender, age, tumour type, tumour stage, and treatment intent. Patients' fitness, based on routine Geriatric-8 (G8) screening, was retrieved from prospectively constructed databases. RESULTS: Between November 2012 and October 2018, 218 older patients with cancer were included in a phase II or III oncology registration trial. Of those, 41 cases with a mean age of 76.0years were included in the analyses. A Fisher's Exact Test revealed a statistical significant difference between cases and matched controls, with a higher proportion of "fit" patients included in phase II or III oncology registration trials compared to the proportion in the matched control group (respectively 70.7% and 41.5%, p<.010). DISCUSSION: We provide evidence for the hypothesis that older patients included in phase II or III oncology trials are significantly fitter than the real life oncology population. Some form of geriatric evaluation should be integrated in future cancer clinical trials to enable stratification according to this parameter and allow subgroup analysis. This will broaden the application and interpretation of trial results.
