Spiritual well-being and associated factors in Dutch patients with advanced cancer
CONTEXT: Palliative care aims to support patients' spiritual needs with the intention of promoting their spiritual well-being (SWB), an important dimension of quality of life. SWB is one of the less-studied dimensions of QoL, particularly in a secular country such as the Netherlands. OBJECTIVES: In this study we aimed to get a better understanding of SWB in Dutch patients with advanced cancer. We therefore examined its prominence and associated factors. METHODS: We used the baseline data of a cohort study on experienced quality of care and quality of life (eQuiPe study), which included 1,103 patients with advanced cancer. In addition to sociodemographic and religious/spiritual characteristics, study measures comprised the SWB subscales Meaning, Peace, and Faith of the revised FACIT-Sp-12, spiritual problems and needs (PNPCsv), quality of life (EORTC-QLQ-C30) and satisfaction with healthcare professionals' interpersonal skills (INPATSAT-32). RESULTS: On average, patients experienced quite a bit of Meaning (8.9, SD 2.3), a little bit to somewhat Peace (6.8, SD 2.7), and very low levels of Faith (2.9, SD 3.7). Two-thirds (71%) of patients reported one or more spiritual problems, for which the majority (54%) wanted to receive attention. In the final multivariable models, only a few factors were associated with SWB, such as greater spiritual needs with lower levels of Meaning and Peace. CONCLUSION: Dutch patients with advanced cancer experience medium to low levels of Meaning, Peace, and Faith. More attention for their SWB is warranted
Periphyton communities as biological polishing agents in mine waste waters and the precipitation process in tailings : final report.
Work on this project was conducted under the auspices of the Canada Centre for Mineral and Energy Technology, Energy, Mines and Resources Canada. DSS file no.: 028SQ.23440-0-9182; DSS contract no.: 23440-0-9182/01SQ; CANMET project no.: 9182; CANMET scientific authority: Ron McCready.Ecological Engineering as a decommissioning technology for acid-generating waste
material from base metal mine sites is being developed on a site in northern Ontario. A
zinc/copper concentrator operated 65 km northeast of Ear Falls for 10 years, producing
about 760,000 short tons of tailings, covering 20 ha, and containing 41 % pyrite and 4 %
pyrrhotite. The tailings are situated above a lake which has acidified during the life of the
mine.
Since 1986 the site has been investigated intensively. This report represents the last
detailed investigation of the hydrology and geochemistry, concentrating on the oxidation
and iron precipitation rates which occur in the tailings mass. These rates define the rate
at which the contaminants are released. The released contaminants entering the acidified
lake are removed in this Ecological Engineered system mainly by different groups of
attached algae. A literature review was carried out to provide a technical framework for
biological removal processes taking place on the site. Water samples collected from piezometers in 1990 were used to confirm that several precipitation processes could take place in the tailings mass or in the surface water
receiving AMD seepage. All piezometer samples show super-saturation with respect to several iron minerals, including ferric hydroxides, aoethite, hematite, letidocrocite, and maanetite, which may be precipitated. Super-saturation with respect to iarosite is shown only by samples from 2 piezometers and Mill Pond.
Samples from piezometers M4 and M10 (and from Mill Pond and Boomerang Landing)
show super-saturation with respect to several aluminum minerals, including alunite, boehmite, diawore, gibbsite, and several clay minerals.
Samples from piezometers M7B, MI 0, M25, M30, M47, M55, Mill Pond, and Dave's Dam
show super-saturation with respect to quartz; those from M7B, MI 0, and M47 also show
super-saturation with respect to gypsum.
Revised sulphide-oxidation rates for the South Bay tailings range from 0.0001 to 0.0427 mol.kg" .yi' (overall average 0.0033 mol.kg-'.yi'). Revised Fe-precipitation rates range
from 0.000009 to 0.001 135 mol.kg-'.yr-' (overall average 0.00025 mol.kg-'.yr-').
The literature review on periphytic algae indicated that algal growth rate data in acidic
metal rich waters are scarce. However, the tolerance mechanisms of periphytic algal
groups which facilitate growth and metal removal from the water were evident.
Extracellular carbon in the form of sheaths or jelly is produced in response to metal and
acid stress by the algal population. Extracellular carbon production is not only related to
metal and acid stress, but also to low nutrients (P and N) in the water or plants. It was concluded that periphytic algae, given their biological polishing characteristics, will indeed prove to be an important contaminant removal process within the Ecological Engineering technology. Research is required to define the conditions which facilitate growth of periphytic algae, and which of the contaminant removal processes (biosieving,
uptake, ad/absorption) is the main contaminant removal process. With this information,
predictions on the contaminant removal capacity of the system can be made. With the
contaminant release rates determined here, the overall effectiveness of biological
polishing as a process can be determined
Predicting Clinical Outcome of Stroke Patients with Tractographic Feature
The volume of stroke lesion is the gold standard for predicting the clinical
outcome of stroke patients. However, the presence of stroke lesion may cause
neural disruptions to other brain regions, and these potentially damaged
regions may affect the clinical outcome of stroke patients. In this paper, we
introduce the tractographic feature to capture these potentially damaged
regions and predict the modified Rankin Scale (mRS), which is a widely used
outcome measure in stroke clinical trials. The tractographic feature is built
from the stroke lesion and average connectome information from a group of
normal subjects. The tractographic feature takes into account different
functional regions that may be affected by the stroke, thus complementing the
commonly used stroke volume features. The proposed tractographic feature is
tested on a public stroke benchmark Ischemic Stroke Lesion Segmentation 2017
and achieves higher accuracy than the stroke volume and the state-of-the-art
feature on predicting the mRS grades of stroke patients. In addition, the
tractographic feature also yields a lower average absolute error than the
commonly used stroke volume feature.Comment: 12 pages, 4 figures, 3 tables. Accepted by MICCAI-BrainLesion 2019 as

Perceptions of involvement in advance care planning and emotional functioning in patients with advanced cancer
Purpose: Advance Care Planning (ACP) is positively associated with the quality of care, but its impact on emotional functioning is ambiguous. This study investigated the association between perceptions of ACP involvement and emotional functioning in patients with advanced cancer. Methods: This study analyzed baseline data of 1,001 patients of the eQuiPe study, a prospective, longitudinal, multicenter, observational study on quality of care and quality of life in patients with advanced cancer in the Netherlands. Patients with metastatic solid cancer were asked to participate between November 2017 and January 2020. Patients’ perceptions of ACP involvement were measured by three self-administered statements. Emotional functioning was measured by the EORTC-QLQ-C30. A linear multivariable regression analysis was performed while taking gender, age, migrant background, education, marital status, and symptom burden into account. Results: The majority of patients (87%) reported that they were as much involved as they wanted to be in decisions about their future medical treatment and care. Most patients felt that their relatives (81%) and physicians (75%) were familiar with their preferences for future medical treatment and care. A positive association was found between patients’ perceptions of ACP involvement and their emotional functioning (b=0.162, p<0.001, 95%CI[0.095;0.229]) while controlling for relevant confounders. Conclusions: Perceptions of involvement in ACP are positively associated with emotional functioning in patients with advanced cancer. Future studies are needed to further investigate the effect of ACP on emotional functioning. Trial registration number: NTR6584 Date of registration: 30 June 2017 Implications for Cancer Survivors: Patients’ emotional functioning might improve from routine discussions regarding goals of future care. Therefore, integration of ACP into palliative might be promising
Trends in publications regarding evidence-practice gaps: A literature review
<p>Abstract</p> <p>Background</p> <p>Well-designed trials of strategies to improve adherence to clinical practice guidelines are needed to close persistent evidence-practice gaps. We studied how the number of these trials is changing with time, and to what extent physicians are participating in such trials.</p> <p>Methods</p> <p>This is a literature-based study of trends in evidence-practice gap publications over 10 years and participation of clinicians in intervention trials to narrow evidence-practice gaps. We chose nine evidence-based guidelines and identified relevant publications in the PubMed database from January 1998 to December 2007. We coded these publications by study type (intervention versus non-intervention studies). We further subdivided intervention studies into those for clinicians and those for patients.

Neuropsychological Sequelae of Carotid Angioplasty with Stent Placement: Correlation with Ischemic Lesions in Diffusion Weighted Imaging
BACKGROUND AND PURPOSE: Few studies investigated the neuropsychological outcome after carotid angioplasty with stent placement (CAS), yielding partially inconsistent results. The present investigation evaluated the effect of CAS in patients with high-grade stenosis and assessed the predictive value of ischemic lesion number for postinterventional cognitive deterioration. METHODS: 22 patients were tested neuropsychologically before and six weeks after CAS. Cerebral ischemic changes were assessed with diffusion weighted imaging (DWI) prior to and after angioplasty. RESULTS: Pre- to postinterventional cognitive performance improved significantly in terms of verbal memory (t = -2.30; p<0.05), whereas significant deterioration was noted regarding verbal memory span (t = 2.31; p<0.05). 8 (36%) persons conformed to the criteria of cognitive improvement. 6 patients (27%) were postinterventionally classified as having deficits. Analysis yielded no statistically significant correlations between lesion quantity and cognitive change. CONCLUSION: Both improvement and deterioration of cognitive functioning was observed in our collective of patients, leaving the neuropsychological outcome after percutaneous transluminal angioplasty unpredictable in individual cases. The presence of acute ischemic lesions on DWI was found to be not tightly associated with cognitive dysfunction after CAS
Short- and long-term effects of a quality improvement collaborative on diabetes management
Introduction: This study examined the short- and long-term effects of a quality improvement collaborative on patient outcomes, professional performance, and structural aspects of chronic care management of type 2 diabetes in an integrated care setting.Methods: Controlled pre- and post-intervention study assessing patient outcomes (hemoglobin A1c, cholesterol, blood pressure, weight, blood lipid levels, and smoking status), professional performance (guideline adherence), and structural aspects of chronic care management from baseline up to 24 months. Analyses were based on 1,861 patients with diabetes in six intervention and nine control regions representing 37 general practices and 13 outpatient clinics.Results: Modest but significant improvement was seen in mean systolic blood pressure (decrease by 4.0 mm Hg versus 1.6 mm Hg) and mean high density lipoprotein levels (increase by 0.12 versus 0.03 points) at two-year follow up. Positive but insignificant differences were found in hemoglobin A1c (0.3%), cholesterol, and blood lipid levels. The intervention group showed significant improvement in the percentage of patients receiving advice and instruction to examine feet, and smaller reductions in the percentage of patients receiving instruction to monitor blood glucose and visiting a dietician annually. Structural aspects of self-management and decision support also improved significantly.Conclusions: At a time of heightened national attention toward diabetes care, our results demonstrate a modest benefit of participation in a multi-institutional quality improvement collaborative focusing on integrated, patient-centered care. The effects persisted for at least 12 months after the intervention was completed.Trial number: http://clinicaltrials.gov Identifier: NCT 00160017
Cigarette smoking, disease severity and autoantibody expression in African Americans with recent-onset rheumatoid arthritis

Cancer specialist nurses’ perspectives of physical activity promotion and the potential role of physical activity apps in cancer care
Purpose: The purpose of this study was to understand breast, prostate and colorectal cancer Clinical Nurse Specialists’ (CNSs) perspectives on physical activity (PA) promotion and the role of smartphone apps to support PA promotion in cancer care.
Methods: CNSs working in breast, prostate or colorectal cancer were recruited via advertisements distributed by professional organisations. In-depth semi-structured telephone interviews were conducted and analysed using thematic analysis.
Results: 19 CNSs participated. The analysis resulted in 4 themes regarding CNSs’ perspectives of PA promotion within cancer care: i) policy changes in survivorship care have influenced CNSs’ promotion of PA; ii) CNSs recognise their role in supporting PA but sit within a wider system necessary for effective PA promotion; iii) CNSs use several techniques to promote PA within their consultations; iv) remaining challenges in PA promotion. The analysis resulted in 3 themes regarding CNSs’ perspectives on the use of apps to promote PA within cancer care: i) the influence of apps on access to PA support; ii) the role of apps in self-directed PA; iii) implementing apps in cancer care. Conclusions: The results of this study provide valuable insight into the CNS role and provide a number of important considerations for the development and implementation of PA interventions within cancer care, with a specific focus on smartphone-based interventions.
Implications for cancer survivors: CNSs play an important role in PA promotion in cancer care and this research can inform the development of PA interventions delivered via smartphone app for people affected by cancer
Digital health behaviour change interventions targeting physical activity and diet in cancer survivors: a systematic review and meta-analysis
Purpose: The number of cancer survivors has risen substantially due to improvements in early diagnosis and treatment. Health behaviours such as physical activity (PA) and diet can reduce recurrence and mortality, and alleviate negative consequences of cancer and treatments. Digital behaviour change interventions (DBCIs) have the potential to reach large numbers of cancer survivors.
Methods: We conducted a systematic review and meta-analyses of relevant studies identified by a search of Medline, EMBASE, PubMed and CINAHL. Studies which assessed a DBCI with measures of PA, diet and/or sedentary behaviour were included.
Results: 15 studies were identified. Random effects meta-analyses showed significant improvements in moderate-vigorous PA (7 studies; mean difference (MD) = 41 minutes per week; 95% CI: 12, 71) and body mass index (BMI)/weight (standardised mean difference (SMD) = -0.23; 95% CI: -0.41, -0.05). There was a trend toward significance for reduced fatigue and no significant change in cancer-specific quality of life (QoL). Narrative synthesis revealed mixed evidence for effects on diet, generic QoL and self-efficacy and no evidence of an effect on mental health. Two studies suggested improved sleep quality.
Conclusions: DBCIs may improve PA and BMI among cancer survivors and there is mixed evidence for diet. The number of included studies is small and risk of bias and heterogeneity was high. Future research should address these limitations with large, high-quality RCTs, with objective measures of PA and sedentary time.
Implications for cancer survivors: Digital technologies offer a promising approach to encourage health behaviour change among cancer survivors
