Multidrug-resistant organisms in paediatric palliative care patients - Prevalence, risk factors and the impact of a liberal hygiene concept.

AIM: Multidrug-resistant organisms (MDRO) deserve special attention in health-care facilities for children with life-limiting conditions because these children have an increased risk for colonisation. To avoid nosocomial transmissions to other inpatients, single-room isolation is usually recommended. In the context of paediatric palliative care (PPC), such isolation counters the aim of participation in social activities for the patients. This study aimed to determine the prevalence of MDRO, the predictive value of risk factors and the incidence of nosocomial infections and nosocomial colonisations on a PPC inpatient unit applying a special hygiene concept that enables participation in social activities through risk-adaption and barrier nursing. METHODS: Two-year surveillance with MDRO screening of all intakes (N = 386) of a PPC unit on the day of admission and discharge. To determine the predictive value of pre-defined risk factors, logistic regression analyses were calculated. Receiver operating characteristic analyses were performed to determine the predictive power of the number of risk factors on the presence of MDRO. RESULTS: The rate of MDRO colonisation at admission was 12.7%; previous positive MDRO screening was the only significant individual risk factor. Over the 2-year period, no MDRO-related nosocomial infections occurred; nosocomial colonisation incidence density was 0.6. CONCLUSION: Results demonstrate that patients with at least one risk factor have to be cared for by barrier nursing until MDRO screening results are negative. Following these guidelines prevents nosocomial MDRO transmission.

The effect of multidrug-resistant organisms on social participation and quality of life in children with life-limiting conditions.

BACKGROUND: Children with life-limiting conditions have a high risk of colonisation with a multidrug-resistant organism (MDRO). To avoid the spread of hospital-aquired infections to other patients, children with a MDRO are moved to an isolated room or ward. However, such isolation prevents social participation, which may reduce the child's quality of life (QoL). To overcome this challenge of conflicting interests on a paediatric palliative care inpatient unit, a hygiene concept for patients colonised with MDRO, called PALLINI, was implemented. PALLINI advises that, instead of isolating the affected children, strict barrier nursing should be used. AIM: To identify the impact of a complex hygiene concept on children's and parents' QoL and social participation. METHODS: Cross-sectional mixed-methods research approach, comprising semi-structured interviews with parents and staff members, and a QoL-questionnaire focusing on the child which was completed by parents. FINDINGS: In paediatric patients with life-limiting conditions who have MDRO colonisation, using a complex hygiene protocol resulted in both benefits and barriers to social participation. However, the child's QoL did not appear to be affected. CONCLUSION: All staff members and families have to be familiar with the hygiene concept and the concept has to be self-explanatory and easy to apply.

Multidrug-Resistant Organisms in Palliative Care: A Systematic Review.

Background: Multidrug-resistant organisms (MDROs) are an important health care issue. Patients in Western societies often present an increased morbidity of chronic conditions accompanied by poor immune status and the use of devices. In particular, patients in palliative care (PC) are at greater risk of MDRO colonization, due to accompanying special devices and being hospitalized. Objective: To gain an overview of the literature regarding MDROs in PC. Design: Systematic review Data sources: On the 19th of October 2019 the databases " PubMed" and " CINAHL" were used to identify studies reporting on MDROs in PC; the search was updated on 16th of May 2020. Results: Seventeen out of 486 articles were included. Six represent qualitative data, 10 quantitative data, and one a mixed methods approach. Prevalence data range from 4.0% to 18%. MDRO colonization has a negative impact on patients and families. It leads to uncertainties and higher workload by staff members. Strategies for the management of MDROs in the field of PC are predominantly available for methicillin-resistant Staphylococcus aureus. Not even half of institutions utilize existing protocols. Recommendations for dealing with MDROs indicate required staff and time resources as well as information, communication, and specific knowledge. Conclusion: There is a great need for studies examining the prevalence of all MDROs in the PC setting. Additionally, not only patients but also a public enlightenment on MDROs should be provided to decrease knowledge gaps and therefore reduce transmission on MDROs.

Opioid-Induced Respiratory Depression in Pediatric Palliative Care Patients with Severe Neurological Impairment-A Scoping Literature Review and Case Reports.

Pediatric Palliative Care (PPC) addresses children, adolescents, and young adults with a broad spectrum of underlying diseases. A substantial proportion of these patients have irreversible conditions accompanied by Severe Neurological Impairment (SNI). For the treatment of pain and dyspnea, strong opioids are widely used in PPC. Nonetheless, there is considerable uncertainty regarding the opioid-related side effects in pediatric patients with SNI, particularly concerning Opioid-Induced Respiratory Depression (OIRD). Research on pain and OIRD in pediatric patients with SNI is limited. Using scoping review methodology, we performed a systematic literature search for OIRD in pediatric patients with SNI. Out of n = 521 identified articles, n = 6 studies were included in the review. Most studies examined the effects of short-term intravenous opioid therapy. The incidence of OIRD varied between 0.13% and 4.6%; besides SNI, comorbidities, and polypharmacy were the most relevant risk factors. Additionally, three clinical cases of OIRD in PPC patients receiving oral or transdermal opioids are presented and discussed. The case reports indicate that the risk factors identified in the scoping review also apply to adolescents and young adults with SNI receiving low-dose oral or transdermal opioid therapy. However, the risk of OIRD should never be a barrier to adequate symptom relief. We recommend careful consideration and systematic observation of opioid therapy in this population of patients.

Subcutaneous or intravenous opioid administration by patient-controlled analgesia in cancer pain: a systematic literature review.

CONTEXT: Opioids administered by various routes are a mainstay of tumour-related pain management. Subcutaneous or intravenous patient-controlled analgesia (PCA) with opioids is an appropriate and safe form of treatment for postoperative pain but studies on this form of administration are sparse in the setting of cancer pain despite widespread use. OBJECTIVE: To evaluate the published studies on opioids administered by subcutaneous and intravenous patient-controlled analgesia for patients with cancer pain. METHODS: Articles were identified from the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 7, 2016), PubMed (Medline; 1975 to 2016) and EMBASE (1974 to 2016). Additional reports were identified from the reference lists of retrieved papers. Studies based on original data with a focus on intravenous or subcutaneous PCA administration of opioids in patients suffering from cancer-related pain were selected. The language was restricted to Dutch, English or German. Predefined information was extracted depending on the topic. RESULTS: Fifty studies published since 1980 met the inclusion criteria. A wide range of study designs, study quality and research objectives were observed. The studies indicated use of standard or by proxy PCA in the inpatient and outpatient setting were safe and useful while significant adverse effects were rarely observed. CONCLUSION: This systematic review of the current evidence suggests PCA can be appropriately used in a wide range of clinical situations.

Effects of nicotine and atomoxetine on brain function during response inhibition.

The nicotinic acetylcholine receptor (nAChR) agonist nicotine and the noradrenaline transporter inhibitor atomoxetine are widely studied substances due to their propensity to alleviate cognitive deficits in psychiatric and neurological patients and their beneficial effects on some aspects of cognitive functions in healthy individuals. However, despite growing evidence of acetylcholine-noradrenaline interactions, there are only very few direct comparisons of the two substances. Here, we investigated the effects of nicotine and atomoxetine on response inhibition in the stop-signal task and we characterised the neural correlates of these effects using blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) at 3T. Nicotine (7 mg dermal patch) and atomoxetine (60 mg per os) were applied to N = 26 young, healthy adults in a double-blind, placebo-controlled, cross-over, within-subjects design. BOLD images were collected during a stop-signal task that controlled for infrequency of stop trials. There were no drug effects on behavioural performance or subjective state measures. However, there was a pronounced upregulation of activation in bilateral prefrontal and left parietal cortex following nicotine during successful compared to unsuccessful stop trials. The effect of nicotine on BOLD during failed stop trials was correlated across individuals with a measure of trait impulsivity. Atomoxetine, however, had no discernible effects on BOLD. We conclude that nicotine effects on brain function during inhibitory control are most pronounced in individuals with higher levels of impulsivity. This finding is compatible with previous evidence of nicotine effects on stop-signal task performance in highly impulsive individuals and implicates the nAChR in the neural basis of impulsivity.

It's All About Communication: A Mixed-Methods Approach to Collaboration Between Volunteers and Staff in Pediatric Palliative Care.

BACKGROUND: Multidisciplinary teamwork is considered central to pediatric palliative care. Although different studies state that volunteers play an essential role in palliative care, little is known about the collaboration between volunteers and staff. AIM: This study aims to explore and compare the perspectives of volunteers and staff regarding collaboration in a pediatric palliative care unit. DESIGN: A mixed-methods approach was chosen to appropriately reflect the complex aspects of collaboration. SETTING/PARTICIPANTS: Both face-to-face interviews with staff who work together with volunteers and a group discussion with all volunteers were conducted. These were supplemented by 2 questionnaires designed for this study that examined participants' characteristics and their estimation of what information volunteers need before they meet a patient. RESULTS: Nine staff members and 7 volunteers participated in this study. Their ideas of collaboration could be grouped into 3 categories: (i) factual level of collaboration, (ii) relationship level of collaboration, and (iii) overall appraisal of collaboration (suggestions for improvement). CONCLUSION: Communication can be considered a key factor in successful collaboration between volunteers and staff. Because many patients in pediatric palliative care units are not able to communicate verbally, good information flow between volunteers and staff is crucial for ensuring quality patient care. Moreover, communication is the key to establishing a team philosophy by clarifying roles and building relationships between volunteers and staff.

Current standards of neuropsychological assessment in epilepsy surgery centers across Europe.

We explored the current practice with respect to the neuropsychological assessment of surgical epilepsy patients in European epilepsy centers, with the aim of harmonizing and establishing common standards. Twenty-six epilepsy centers and members of "E-PILEPSY" (a European pilot network of reference centers in refractory epilepsy and epilepsy surgery), were asked to report the status of neuropsychological assessment in adults and children via two different surveys. There was a consensus among these centers regarding the role of neuropsychology in the presurgical workup. Strong agreement was found on indications (localization, epileptic dysfunctions, adverse drugs effects, and postoperative monitoring) and the domains to be evaluated (memory, attention, executive functions, language, visuospatial skills, intelligence, depression, anxiety, and quality of life). Although 186 different tests are in use throughout these European centers, a core group of tests reflecting a moderate level of agreement could be discerned. Variability exists with regard to indications, protocols, and paradigms for the assessment of hemispheric language dominance. For the tests in use, little published evidence of clinical validity in epilepsy was provided. Participants in the survey reported a need for improvement concerning the validity of the tests, tools for the assessment of everyday functioning and accelerated forgetting, national norms, and test co-normalization. Based on the present survey, we documented a consensus regarding the indications and principles of neuropsychological testing. Despite the variety of tests in use, the survey indicated that there may be a core set of tests chosen based on experience, as well as on published evidence. By combining these findings with the results of an ongoing systematic literature review, we aim for a battery that can be recommended for the use across epilepsy surgical centers in Europe.

Sorafenib and azacitidine as salvage therapy for relapse of FLT3-ITD mutated AML after allo-SCT.

OBJECTIVE: Patients with acute myeloid leukemia (AML) carrying FLT3-ITD mutations (FLT3-ITD+) who relapse after allogeneic transplantation (allo-SCT) have a very dismal prognosis with the currently available treatment options. METHODS: We treated eight patients with FLT3-ITD+ AML who had relapsed in median 91 d (range, 28-249) following allo-SCT with a combination of the multikinase inhibitor sorafenib and the DNA methyltransferase inhibitor azacitidine (Aza). RESULTS: Patients received a median of five cycles of Aza (range, 2-9) and sorafenib with a median daily dosage of 750 mg (range 400-800) for 129 d (range, 61-221). Six of eight patients received donor lymphocyte infusions (DLI) with a median number of two DLI per patient (range, 1-4). Following this treatment, four patients (50%) achieved a complete remission and three of them a complete molecular remission. Median duration of CR was 182 d (range, 158-406), and two patients remain in ongoing remission for 406 and 168 d. Median overall survival was 322 d (range, 108-574 d) with three patients being currently alive. CONCLUSION: Taken together, the combination of sorafenib, Aza, and DLI shows promising efficacy and deserves further evaluation in larger patient groups.

Use of complementary and alternative medicine by pediatric oncology patients during palliative care.

PURPOSE: Although the popularity of complementary and alternative medicine (CAM) has risen in the last decade, information about its use by pediatric patients in palliative care is still scarce. The purpose of the study was to assess the frequency and types of CAM administered by parents with children suffering from cancer during the palliative phase. METHODS: All parents who lost their child due to cancer in the federal state North Rhine Westfalia/Germany were eligible for the study. The first group of eligible parents was contacted in 1999-2000 and a second group of parents in 2005-2006. Upon agreement, parents were asked to complete a semi-structured questionnaire about the frequency of CAM use and the specific treatments that had been used. The types of CAM were categorized according to the National Center for Complementary and Alternative Medicine (NCCAM). RESULTS: A total of 96 parents participated in the study (48 in each cohort). Forty-three percent of all parents in both groups reported CAM use. The results show an increase of CAM use from 38 % in the first group to 49 % in the second cohort of pediatric patients during palliative care. The most common types of CAM used in both groups were homeopathy and treatment with mistletoe preparations. CONCLUSIONS: The study provides information about usage of CAM in children suffering from cancer during the palliative phase of the disease. Further research is required to investigate benefits, potential adverse effects, and the potential efficacy of CAM in this population.

DEK oncogene expression during normal hematopoiesis and in Acute Myeloid Leukemia (AML).

DEK is important in regulating cellular processes including proliferation, differentiation and maintenance of stem cell phenotype. The translocation t(6;9) in Acute Myeloid Leukemia (AML), which fuses DEK with NUP214, confers a poor prognosis and a higher risk of relapse. The over-expression of DEK in AML has been reported, but different studies have shown diminished levels in pediatric and promyelocytic leukemias. This study has characterized DEK expression, in silico, using a large multi-center cohort of leukemic and normal control cases. Overall, DEK was under-expressed in AML compared to normal bone marrow (NBM). Studying specific subtypes of AML confirmed either no significant change or a significant reduction in DEK expression compared to NBM. Importantly, the similarity of DEK expression between AML and NBM was confirmed using immunohistochemistry analysis of tissue mircorarrays. In addition, stratification of AML patients based on median DEK expression levels indicated that DEK showed no effect on the overall survival of patients. DEK expression during normal hematopoiesis did reveal a relationship with specific cell types implicating a distinct function during myeloid differentiation. Whilst DEK may play a potential role in hematopoiesis, it remains to be established whether it is important for leukemagenesis, except when involved in the t(6;9) translocation.

Did increased availability of pediatric palliative care lead to improved palliative care outcomes in children with cancer?

BACKGROUND: Awareness for pediatric palliative care in children with cancer increased in the last ten years in Germany. In this study we sought to determine whether this change in awareness led to improved palliative care outcomes in children dying due to cancer. METHODS: In 2005 we interviewed a cohort of 48 bereaved parents who had a lost a child to cancer approximately five years earlier (2000 cohort), and in 2010 we interviewed another cohort of 48 parents who had lost a child due to cancer approximately five years before (2005 cohort). Children of the 2000 cohort were cared for by six specialized oncology departments in North-Rhine-Westphalia (NRW), Germany, and children of the 2005 cohort by 16 specialized pediatric oncology departments in NRW, Germany. Parents of both cohorts were interviewed using the Survey of Caring for Children with Cancer (SCCC). RESULTS: The children of both parental cohorts were similar in terms of disease characteristics and sociodemographic variables. Children suffered in a very similar manner from core symptoms such as pain and dyspnea. However, symptom treatment increased for all symptoms. In case of treatment of anxiety the increase was statistically significant (p=0.035). Location of care changed with almost three-quarters of the 2005 cohort receiving palliative home care, significantly more than in the 2000 cohort (p=0.007). Additionally, fewer children of the 2005 cohort died in the intensive care unit. CONCLUSION: While the location of care during the end-of-life period shifted (from hospital to home), there remains substantial work to ease the suffering in children with cancer at end of life.
