Subarctic lakes are sentinels of climate change, showing responses in their physical, chemical, and biological properties. However, climate-induced changes in invertebrate diversity and their underlying mechanisms are not fully understood. We explored the relationship between past climate change and taxonomic composition of subfossil cladocerans in a subarctic lake during the last ca.

In the 1980s, liming became a large-scale, governmentally supported restoration program implemented by many countries to mitigate the effects of acidification of freshwaters. Despite some 50 years of liming of thousands of lakes and streams, its efficacy remains largely debated. This study is the first of its kind to use paleolimnological reconstructions using both subfossil chironomid assemblages and their carbon stable isotopic composition to compare the ecological trajectories of limed and control (unlimed) lakes over the last 100 years in order to unravel the effects of liming on Scandinavian lakes.

Background: This study aimed to assess whether ecological inferences from isotopic functional indices (IFIs) are impacted by changes in isotopic baselines in aquatic food webs. We used sudden CO-outgassing and associated shifts in DIC- C brought by waterfalls as an excellent natural experimental set-up to quantify impacts of changes in algal isotopic baselines on ecological inferences from IFIs.

Methods: Carbon ( C) and nitrogen ( N) stable isotopic ratios of invertebrate communities sharing similar structure were measured at above- and below-waterfall sampling sites from five rivers and streams in Southern Quebec (Canada).

Purpose: This study evaluated the effect of early integrated palliative care (PC) in oncology on quality of life (QOL) near the end of life and use of health care resources near the end of life.

Method: Patients with advanced cancer and a life expectancy of approximately 1 year were randomly assigned to either early and systematic integration of PC into oncological care (intervention) or standard oncological care alone (control). QOL was assessed with the EORTC QLQ-C30 global health status/QOL scale and McGill Quality of Life (MQOL) Single Item Scale and Summary Scale at baseline, 12 weeks and 6 weekly thereafter until death.

Reconstructions of past food web dynamics are necessary for better understanding long-term impacts of climate change on subarctic lakes. We studied elemental and stable isotopic composition of sedimentary organic matter, photosynthetic pigments and carbon stable isotopic composition of Daphnia (Cladocera; Crustacea) resting eggs (δC) in a sediment record from a small subarctic lake. We examined how regional climate and landscape changes over the last 5800 years affected the relative importance of allochthonous and autochthonous carbon transfer to zooplankton.

Context: Although early integrated palliative home care (PHC) is believed to be beneficial for patients with chronic obstructive pulmonary disease (COPD), trials testing this hypothesis are rare and show inconclusive results.

Objectives: To test feasibility, acceptability, and preliminary effectiveness of early integrated PHC for end-stage COPD.

Methods: Testing a six-month early integrated PHC pilot randomized controlled trial given by palliative home care nurses (PHCNs) for end-stage COPD with five components: 1) preinclusion COPD support training for PHCNs; 2) monthly PHC visits; 3) leaflets on coping mechanisms; 4) a protocol on symptom management and support, a care plan and an action plan; and 5) integration of PHC and usual care through reporting and communication mechanisms.

Objectives: Recent studies have shown that the early provision of palliative care (PC) integrated into oncology in the hospital has beneficial effects on the quality of life of people who are dying and their family caregivers. However, a model to integrate palliative home care (PHC) early in oncology care is lacking. Therefore, our aim is to develop the Early Palliative Home care Embedded in Cancer Treatment (EPHECT) intervention.

Background: In current cancer care, multidisciplinary team meetings (MDTMs) aim at uniting care professionals from different disciplines to decide upon the best possible treatment plan for the patients based on the available scientific evidence. In Belgium, the multidisciplinary approach is mandatory and formally regulated since 2003. Current research indicates that MDTMs are not always truly multidisciplinary, ie, with a mix of medical as well as paramedical disciplines, and that the medical profession (physicians and medical specialists) tends to dominate the interaction in MDTMs.

Objectives: Palliative care is still often involved late in the disease trajectory. Recently, some studies have explored the barriers to early integration of PC in the hospital setting. Because palliative care home care (PHC) is organised differently compared with PC in a hospital setting, the identification of barriers to the early integration of PHC is needed.

Background: Research suggests that palliative home care should be integrated early into standard care for end-stage COPD patients. Patients also express the wish to be cared for and to die at home. However, a practice model for early integration of palliative home care (PHC) into standard care for end-stage COPD has not been fully developed.

Purpose: To prevent febrile neutropenia (FN), European Organisation for Research and Treatment of Cancer (EORTC) guidelines recommend primary prophylaxis with granulocyte colony-stimulating factors (PPG) for patients at high risk (≥ 20%) of FN. In Belgium, the use of PPG is restricted by specific reimbursement criteria. The impact of these criteria on PPG use and adherence to guidelines is unknown.

Early integration of palliative home care (PHC) might positively affect people with chronic obstructive pulmonary disease (COPD). However, PHC as a holistic approach is not well integrated in clinical practice at the end-stage COPD. General practitioners (GPs) and community nurses (CNs) are highly involved in primary and home care and could provide valuable perspectives about barriers to and facilitators for early integrated PHC in end-stage COPD.

Background: To date, no randomised controlled trials on the integration of specialised palliative home care into oncology care have been identified. Information on whether existing models of integrated care are applicable to the home care system and how working procedures and skills of the palliative care teams might require adaptation is missing.

Aim: To gain insight into differences between early and late involvement and the effect on existing working procedures and skills as perceived by palliative home care teams.

Background: Multidisciplinary team meetings (MDTMs) have become standard practice in oncology and gained the status of the key decision-making forum for cancer patient management. The current literature provides evidence that MDTMs are achieving their intended objectives but there are also indications to question the positive impact of MDTMs in oncology settings. For cancer management to be patient-centered, it is crucial that medical information as well as psychosocial aspects-such as the patients' living situation, possible family problems, patients' mental state, and patients' perceptions and values or preferences towards treatment or care-are considered and discussed during MDTMs.

Background: The benefit of early integration of palliative care into oncological care is suggested to be due to increased psychosocial support. In Belgium, psychosocial care is part of standard oncological care. The aim of this randomised controlled trial is to examine whether early and systematic integration of palliative care alongside standard psychosocial oncological care provides added benefit compared with usual care.

Aim: Nowadays, extracellular vesicles are of great interest in prostate cancer (PCa) research. Asparagine (N)-linked glycosylation could play a significant role in the pathological mechanism of these vesicles. We investigated if prostatic protein N-glycosylation profiles were related to urinary vesicle-associated prostate-specific antigen (PSA) extractability and if this parameter showed diagnostic potential for PCa.
