- Abstract
The INTERSPEECH 2018 Computational Paralinguistics Challenge addresses four different problems for the first time in a research competition under well-defined conditions: In the Atypical Affect Sub-Challenge, four basic emotions annotated in the speech of handicapped subjects have to be classified; in the Self-Assessed Affect Sub-Challenge, valence scores given by the speakers themselves are used for a three-class classification problem; in the Crying Sub-Challenge, three types of infant vocalisations have to be told apart; and in the Heart Beats Sub-Challenge, three different types of heart beats have to be determined. We describe the Sub-Challenges, their conditions and baseline feature extraction and classifiers, which include data-learnt (supervised) feature representations by end-to-end learning, the ‘usual’ ComParE and BoAW features and deep unsupervised representation learning using the AUDEEP toolkit for the first time in the challenge series.

- Abstract
© 2018 Elsevier Ltd Background: Early speech-language development of individuals with Rett syndrome (RTT) has been repeatedly characterised by a co-occurrence of apparently typical and atypical vocalisations. Aims: To describe specific features of this intermittent character of typical versus atypical early RTT-associated vocalisations by combining auditory Gestalt perception and acoustic vocalisation analysis. Methods and procedures: We extracted N = 363 (pre-)linguistic vocalisations from home video recordings of an infant later diagnosed with RTT. In a listening experiment, all vocalisations were assessed for (a)typicality by five experts on early human development. Listeners’ auditory concepts of (a)typicality were investigated in context of a comprehensive set of acoustic time-, spectral- and/or energy-related higher-order features extracted from the vocalisations. Outcomes and results: More than half of the vocalisations were rated as ‘atypical’ by at least one listener. Atypicality was mainly related to the auditory attribute ‘timbre’ and to prosodic, spectral, and voice quality features in the acoustic domain. Conclusions and implications: Knowledge gained in our study shall contribute to the generation of an objective model of early vocalisation atypicality. Such a model might be used for increasing caregivers’ and healthcare professionals’ sensitivity to identify atypical vocalisation patterns, or even for a probabilistic approach to automatically detect RTT based on early vocalisations.

- Abstract
Background: Responding to one's own name (RtN) has been reported as atypical in children with developmental disorders, yet comparative studies on RtN across syndromes are rare. Aims: We aim to (a) overview the literature on RtN in different developmental disorders during the first 24 months of life, and (b) report comparative data on RtN across syndromes. Methods and procedures: In Part 1, a literature search, focusing on RtN in children during the first 24 months of life with developmental disorders, identified 23 relevant studies. In Part 2, RtN was assessed utilizing retrospective video analysis for infants later diagnosed with ASD, RTT, or FXS, and typically developing peers. Outcomes and results: Given a variety of methodologies and instruments applied to assess RtN, 21/23 studies identified RtN as atypical in infants with a developmental disorder. We observed four different developmental trajectories of RtN in ASD, RTT, PSV, and FXS from 9 to 24 months of age. Between-group differences became more distinctive with age. Conclusions and implications: RtN may be a potential parameter of interest in a comprehensive early detection model characterising age-specific neurofunctional biomarkers associated with specific disorders, and contribute to early identification.

- Abstract
Background: After the acquisition of basic grammatical skills, narrative competence gradually develops in preschool and primary school age, including the subsequent elaboration of syntactic complexity and the use cohesive elements. In addition, the adequate use of lexical means is an important component of story-telling. Previous research has shown children with language impairment have substantial difficulty when telling stories. Their deficits affect both the microstructural and the macrostructural level. Since lexical competence is relevant for narrative competence and lexical problems are often part of language impairment, the present study investigates the quantity, diversity, and composition of the lexicon in oral narratives. Method: The first, cross-sectional study includes 100 monolingual, typically developing (TD), German-speaking children at age 3;0-6;0. The children narrated three picture stories. The number of types, tokens, types-token ratio, mean length of utterance (MLU) and lexical composition were analysed. Results demonstrate that vocabulary size, as well as lexical composition, did not change over time, while lexical diversity and MLU increased with age. In study 2, a comparison of 34 children with language impairment (LI) and 34 age-matched TD children from study 1 shows a limited lexical diversity and a significantly lower MLU for children with LI. Children with LI used more nouns and more personal-social words, but fewer pronouns. Discussion: Vocabulary size and the use of word categories in children with LI are broadly similar to that of TD children. However, oral narratives of children with LI are characterized by a limited lexical diversity and shorter utterances. In addition, subtle differences with respect to the use of word categories were found, which are more typical for earlier phases of language development.

- Abstract
© 2017, The Author(s). Purpose of Review: Substantial research exists focusing on the various aspects and domains of early human development. However, there is a clear blind spot in early postnatal development when dealing with neurodevelopmental disorders, especially those that manifest themselves clinically only in late infancy or even in childhood. Recent Findings: This early developmental period may represent an important timeframe to study these disorders but has historically received far less research attention. We believe that only a comprehensive interdisciplinary approach will enable us to detect and delineate specific parameters for specific neurodevelopmental disorders at a very early age to improve early detection/diagnosis, enable prospective studies and eventually facilitate randomised trials of early intervention. Summary: In this article, we propose a dynamic framework for characterising neurofunctional biomarkers associated with specific disorders in the development of infants and children. We have named this automated detection ‘Fingerprint Model’, suggesting one possible approach to accurately and early identify neurodevelopmental disorders.

- Abstract
We reviewed original research papers that used quantifiable technology to detect early autism spectrum disorder (ASD) and identified 376 studies from 34 countries from 1965 to 2013. Publications have increased significantly since 2000, with most coming from the USA. Electroencephalogram, magnetic resonance imaging and eye tracking were the most frequently used technologies. Conclusion The use of quantifiable technology to detect early ASD has increased in recent decades, but has had limited impact on early detection and treatment. Further scientific developments are anticipated, and we hope that they will increasingly be used in clinical practice for early ASD screening, diagnosis and intervention.

- Abstract
Eye tracking is a noninvasive technique based on infrared video technology that is used to analyze eye movements. Such analyses might provide insights into perceptual and cognitive capacities. It is a method widely used in various disciplines, such as ophthalmology, neurology, psychiatry and neuropsychology for basic science, but also clinical practice. For example, recent studies on children who were later diagnosed with autism spectrum disorders revealed early abnormal eye movement patterns in socio-communicative settings; children with dyslexia appeared to also have peculiar eye movement patterns, expressed in longer fixation durations and smaller saccades while reading. Current research using eye tracking systems in combination with neurophysiological and brain imaging techniques will add to a better understanding of cognitive, linguistic and socio-communicative development and in the near future possibly also lead to a broader clinical application of this method.

- Abstract
© 2015 Elsevier Ireland Ltd. Background: Little is known about the first half year of life of individuals later diagnosed with autism spectrum disorders (ASD). There is even a complete lack of observations on the first 6. months of life of individuals with transient autistic behaviours who improved in their socio-communicative functions in the pre-school age. Aim: To compare early development of individuals with transient autistic behaviours and those later diagnosed with ASD. Study design: Exploratory study; retrospective home video analysis. Subjects: 18 males, videoed between birth and the age of 6. months (ten individuals later diagnosed with ASD; eight individuals who lost their autistic behaviours after the age of 3 and achieved age-adequate communicative abili ties, albeit often accompanied by tics and attention deficit). Method: The detailed video analysis focused on general movements (GMs), the concurrent motor repertoire, eye contact, responsive smiling, and pre-speech vocalisations. Results: Abnormal GMs were observed more frequently in infants later diagnosed with ASD, whereas all but one infant with transient autistic behaviours had normal GMs (p. < . 0.05). Eye contact and responsive smiling were inconspicuous for all individuals. Cooing was not observable in six individuals across both groups. Conclusions: GMs might be one of the markers which could assist the earlier identification of ASD. We recommend implementing the GM assessment in prospective studies on ASD.

- Abstract
This study compared early markers of social reciprocity in children with typical Rett syndrome (RTT) and in those with the preserved speech variant (PSV) of RTT. Retrospective video analysis of 10 toddlers with typical RTT and five with PSV investigated participants' orientation to their name being called between the ages of 5 and 24 months, prior to their diagnosis. From analysis of the recordings two distinct profiles were apparent. Although response rate was higher in girls with typical RTT than PSV at 5 to 8 months this noticeably reversed from 9 to 12 months onwards. By two years of age there was a markedly higher rate and range of responses from girls with PSV. This study contributes to the delineation of different profiles for the variants of RTT.

- Abstract
We review literature identifying an association between motor abnormality in the first 5 months of infancy and later diagnosis of autism spectrum disorder (ASD) or Rett syndrome (RTT). The assessment of the quality of early spontaneous movements (also known as the assessment of general movements; GMs) is a diagnostic tool that has repeatedly proven to be valuable in detecting early markers for neurodevelopmental disorders. Even though the rate of occurrence of abnormal GMs is exceedingly high in infants later diagnosed with ASD, we endorse further studies using this method either based on family videos or its prospective implementation in high-risk sibling studies to evaluate the power of GM assessment as one potential marker for early maldevelopment in this cohort. © 2013 Elsevier Ltd.

- Abstract
OBJECTIVES: To provide an overview of the indications for hematopoietic stem cell transplantation (HSCT), including standard-of-care and experimental diseases. DATA SOURCES: Research studies, book chapters, websites, and articles describing diseases treated with HSCT. CONCLUSION: The indications for HSCT are continually changing and expanding rapidly beyond the traditional use as a treatment for malignant and non malignant diseases. IMPLICATIONS FOR NURSING PRACTICE: Nurses who care for transplant patients will need to become knowledgeable of not only the diseases treated traditionally with HSCT, but also the many other diseases or disorders in which HSCT may play a role.

30. The Cooperative Care Model: an innovative approach to deliver blood and marrow stem cell transplant care.

- Abstract
Competition among healthcare institutions, the need to improve outcomes, and the desire to decrease costs have motivated blood and marrow stem cell transplant centers to develop innovative care models. In an effort to meet these challenges, a major midwestern medical center adapted the transplant process to the outpatient setting. This transition created greater educational and care demands for patients and families. To address these demands and provide improved accommodations and amenities for patients and families, the center adopted an innovative model of care, Cooperative Care, for transplant recipients. Cooperative Care embraces patients and families as key members of the healthcare team. A family member serves as a primary caregiver for the patient during the acute inpatient phase of the transplant. Care becomes more personal and individualized, cost is reduced, the rate of rehospitalization potentially is decreased, and patients ultimately become more confident and competent in caring for themselves. The healthcare team shifted its care philosophy to incorporate a care partner, increase patient control and independence, and create greater emphasis on education. Outcomes, including patient satisfaction, have demonstrated success and motivated expansion of this model to other patient populations. [ABSTRACT FROM AUTHOR]

Catheter-associated infections markedly contribute to treatment failure in peritoneal dialysis (PD) patients. There is much controversy surrounding prophylactic strategies to prevent these infections.In this nationwide multicenter study we analyzed strategies to prevent catheter-associated infections as performed in Austrian PD centers in 2006. A questionnaire was sent to all 23 PD centers in Austria.Ten different catheter models were used in the 332 patients being treated in the 23 Austrian PD centers. Systemic antibiotics prior to catheter placement were given by 17 of the 23 PD centers (glycopeptides, n = 7; cephalosporins, n = 10). Nasal swabs were taken preoperatively by 17 PD centers; nasal Staphylococcus aureus carriers were treated prophylactically with mupirocin cream in 15 of these centers. Dressing change was routinely performed in 318 of 332 chronic PD patients (nonocclusive film dressing, n = 58; gauze dressing, n = 260). Disinfectants for chronic exit-site care included povidone iodine (n = 155), sodium hypochlorite (n = 31), povidone iodine + sodium hypochlorite together (n = 102), and octenidine dihydrochloride/phenoxyethanol (n = 17). Water + non-disinfectant soap or 0.9% sodium chloride was administered as a cleansing agent to the exit site by 27 patients. Routine S. aureus screening (nasal and/or exit-site swabs) in chronic PD patients was performed in 12 PD centers; carriers were treated with mupirocin cream in 11 of these centers. Dialysis staff members were screened for S. aureus in 8 PD centers and spouses were screened for S. aureus in 5 PD centers. The overall exit-site infection rate was 1 episode/43.9 patient-months, tunnel infection rate was 1 episode/88.9 patient-months, and peritonitis rate was 1 episode/51.0 patient-months. Patients of centers that have installed a prophylaxis protocol for treating S. aureus carriers had lower mean infection rates compared with those not using such a protocol.Various individual prophylactic strategies are used to prevent catheter-associated infections in Austrian PD centers. Infection rates are within the range reported in the literature. There is still scope for improvement in some centers (e.g., by establishing a prophylaxis protocol).

- Abstract
Introduction: At the present time, the skin tumors are among the most common cancers. Optimal therapy is based on the extent of the disease and the age of the patient. The need for radiotherapy occurs for inoperable locally advanced tumors and in the event of failure, salvage surgery is applied., Materials and Methods: We provided a case report of an older patient with giant squamous cell skin carcinoma and a review of published articles., Results: We present a rare case of giant squamous cell skin carcinoma with metastatic satellite tumors that was primarily treated with curative radiotherapy. Five months after radiotherapy, a recurrent tumor was detected at the site of origin and the treatment was completed by salvage surgery. Full remission was achieved for four years., Conclusion: Despite the seemingly incurable finding it is always necessary to consider radical treatment regardless of the patient´s age. Curative treatment could achieve long term remission in the group of older patients., (© 2019 Greater Poland Cancer Centre. Published by Elsevier B.V. All rights reserved.)

- Abstract
Purpose: Chronic Achilles tendinopathy is one of the most common causes of malfunction and pain, which can lead to a significant reduction of the quality of life. The hypothesis of this study argues that autologous conditioned serum (i.e. Orthokine) injections in chronic midportion Achilles tendinopathy have a better outcome than eccentric training., Methods: This study investigates, retrospectively, the effects of peritendinous autologous conditioned serum injections as compared to standard eccentric training in 50 patients with chronic Achilles tendinopathy between 2012 and 2015. Before injection or eccentric training and 6 weeks, 12 weeks and 6 months thereafter, the patients were assessed by means of the VISA-A-G score (Victorian Institute of Sport Assessment-Achilles questionnaire-German). An MRI was also performed before and 6 months after injection and eccentric training., Results: Both patient groups had statistically significant better VISA-A-G scores after injection or eccentric training compared to the baseline before injection (90 vs 40, respectively, P < 0.001) or eccentric training (81 vs 47, respectively, P < 0.001). Comparing the baseline corrected VISA-A-G scores, patients in the autologous-conditioned-serum-group had significantly higher changes in VISA-A-G scores than the eccentric-training-group after 12 weeks (40 vs 36, P = 0.018) and 6 months (50 vs 34, P = 0.034). Both patient groups had statistically significant (P < 0.001) reduction of tendon thickness (autologous conditioned serum: 0.32; eccentric training: 0.24) and length of bursa (autologous conditioned serum: 0.24; eccentric training: 0.21) as well as significant (P < 0.001) improvement of tendon quality in MRI (autologous conditioned serum: 14 vs 1; eccentric training: 14 vs 2). There were no statistical differences in MRI-findings between the two groups., Conclusion: Both therapies led to improvement of MRI-findings, including reduction of tendon thickness and tendon quality. Autologous-conditioned-serum-injections show greater clinical long-term benefit as compared to eccentric training and, therefore, offers a good alternative to eccentric training., Level of Evidence: Therapeutic studies, Level III.

- Abstract
Patient, caregiver, and family education and support was 1 of 6 key areas of interest identified by the National Marrow Donor Program/Be The Match 2-year project to prioritize patient-centered outcomes research (PCOR) goals for the blood and marrow transplantation (BMT) community. PCOR focuses on research to help patients and their caregivers make informed decisions about health care. Therefore, each area of interest was assigned to a working group with broad representation, including patients, caregivers, and clinicians. Each working group was charged with identifying gaps in knowledge and making priority recommendations for critical research to fill those gaps. The report from this working group presents a conceptual framework to address gaps in knowledge regarding patient and caregiver education in BMT and recommendations for priority research questions on this topic., (Copyright © 2019.

- Abstract
The goal of patient-centered outcomes research (PCOR) is to help patients and those who care for them make informed decisions about healthcare. However, the clinical research enterprise has not involved patients, caregivers, and other nonproviders routinely in the process of prioritizing, designing, and conducting research in hematopoietic cell transplantation (HCT). To address this need the National Marrow Donor Program/Be The Match engaged patients, caregivers, researchers, and other key stakeholders in a 2-year project with the goal of setting a PCOR agenda for the HCT community. Through a collaborative process we identified 6 major areas of interest: (1) patient, caregiver, and family education and support; (2) emotional, cognitive, and social health; (3) physical health and fatigue; (4) sexual health and relationships; (5) financial burden; and (6) models of survivorship care delivery. We then organized into multistakeholder working groups to identify gaps in knowledge and make priority recommendations for critical research to fill those gaps. Gaps varied by working group, but all noted that a historical lack of consistency in measures use and patient populations made it difficult to compare outcomes across studies and urged investigators to incorporate uniform measures and homogenous patient groups in future research. Some groups advised that additional pre-emptory work is needed before conducting prospective interventional trials, whereas others were ready to proceed with comparative clinical effectiveness research studies. This report presents the results of this major initiative and makes recommendations by working group on priority questions for PCOR in HCT., (Copyright © 2018 The American Society for Blood and Marrow Transplantation.

- Abstract
A projected shortage of hematopoietic cell transplantation (HCT) health professionals was identified as a major issue during the National Marrow Donor Program/Be The Match System Capacity Initiative. Work-related distress and work-life balance were noted to be potential barriers to recruitment/retention. This study examined these barriers and their association with career satisfaction across HCT disciplines. A cross-sectional, 90-item, web-based survey was administered to advanced practice providers, nurses, physicians, pharmacists, and social workers in 2015. Participants were recruited from membership lists of 6 professional groups. Burnout (measured with the Maslach Burnout Inventory subscales of emotional exhaustion and depersonalization) and moral distress (measured by Moral Distress Scale-Revised) were examined to identify work-related distress. Additional questions addressed demographics, work-life balance, and career satisfaction. Of 5759 HCT providers who received an individualized invitation to participate, 914 (16%) responded; 627 additional participants responded to an open link survey. Significant differences in demographic and practice characteristics existed across disciplines (P < .05). The prevalence of burnout differed across disciplines (P < .05) with an overall prevalence of 40%. Over one-half of pharmacists had burnout, whereas social workers had the lowest prevalence at less than one-third. Moral distress scores ranged from 0 to 336 and varied by discipline (P < .05); pharmacists had the highest mean score (62.9 ± 34.8) and social workers the lowest (42.7 ± 24.4). In multivariate and univariate analyses, variables contributing to burnout varied by discipline; however, moral distress was a significant contributing factor for all providers. Those with burnout were more likely to report inadequate work-life balance and a low level of career satisfaction; however, overall there was a high level of career satisfaction across disciplines. Burnout, moral distress, and inadequate work-life balance existed at a variable rate in all HCT disciplines, yet career satisfaction was high. These results suggest specific areas to address in the work environment for HCT health professionals, especially the need for relief of moral distress and a greater degree of personal time. As the creation of healthy work environments is increasingly emphasized to improve quality care and decrease costs, these findings should be used by HCT leadership to develop interventions that mitigate work-related distress and in turn foster recruitment and retention of HCT providers., (Copyright © 2017 The American Society for Blood and Marrow Transplantation.

- Abstract
Hematopoietic cell transplantation (HCT) survivors are at risk for development of late complications and require lifelong monitoring for screening and prevention of late effects. There is an increasing appreciation of the issues related to healthcare delivery and coverage faced by HCT survivors. The 2016 National Institutes of Health Blood and Marrow Transplant Late Effects Initiative included an international and broadly representative Healthcare Delivery Working Group that was tasked with identifying research gaps pertaining to healthcare delivery and to identify initiatives that may yield a better understanding of the long-term value and costs of care for HCT survivors. There is a paucity of literature in this area. Critical areas in need of research include pilot studies of novel and information technology supported models of care delivery and coverage for HCT survivors along with development and validation of instruments that capture patient-reported outcomes. Investment in infrastructure to support this research, such as linkage of databases including electronic health records and routine inclusion of endpoints that will inform analyses focused around care delivery and coverage, is required., (Copyright © 2017 The American Society for Blood and Marrow Transplantation.

- Abstract
In the United States, insurance status has been implicated as a barrier to obtaining timely treatment. In this retrospective cohort study of 521 patients who underwent first hematopoietic cell transplantation (HCT), we investigated the association between timeliness of HCT and overall survival. Timeliness was operationally defined in the following 3 ways: (1) payer approval, from request for approval to actual payer approval; (2) transplantation speed, from payer approval to time of actual HCT; and (3) total time, from request for approval to HCT. Patients with private insurance had longer time to payer approval (P < .0001) than those with public payers but shorter time from approval to actual HCT (P < .0001) and total time to HCT (P < .0001). Multivariate Cox regression showed no significant differences in risk of death between slow and fast times in the 3 indices of timeliness in the models that used all patients (n = 509), autologous HCT in lymphoma (n = 278), and autologous HCT in multiple myeloma (n = 121). Additional studies to evaluate the effect of insurance timeliness on all patients for whom HCT is recommended, not just those who undergo HCT, should be conducted., (Copyright © 2016 The American Society for Blood and Marrow Transplantation.

44. Coordination of terpyridine to Li+ in two different ionic liquids.

Pokorny K, Schmeisser M, Hampel F, Zahl A, Puchta R, and van Eldik R
- Abstract
On the basis of (7)Li NMR experiments, the complex-formation reaction between Li(+) and the tridentate N-donor ligand terpyridine was studied in the ionic liquids [emim][NTf2] and [emim][ClO4] as solvents. For both ionic liquids, the NMR data implicate the formation of [Li(terpy)2](+). Density functional theory calculations show that partial coordination of terpyridine involving the coordination of a solvent anion can be excluded. In contrast to the studies in solution, X-ray diffraction measurements led to completely different results. In the case of [emim][NTf2], the polymeric lithium species [Li(terpy)(NTf2)]n was found to control the stacking of this complex, whereas crystals grown from [emim][ClO4] exhibit the discrete dimeric species [Li(terpy)(ClO4)]2. However, both structures indicate that each lithium ion is formally coordinated by one terpy molecule and one solvent anion in the solid state, suggesting that charge neutralization and π stacking mainly control the crystallization process.

- Abstract
Hematopoietic cell transplantation (HCT) is the only known curative therapy for many patients with life-threatening hematologic and oncologic diseases. It is estimated that the National Marrow Donor Program(®) (NMDP) will facilitate 10,000 transplants by 2015, double the current number. To better understand the existing personnel and center infrastructure for HCT in the country and to address system capacity challenges to the future growth of HCT, the NMDP convened a diverse group of stakeholders and thought leaders representing HCT physicians, physician assistants, nurse practitioners, nurses, pharmacists, other healthcare providers, HCT program directors, hospital administrators, payors, and professional organizations. Working groups were formed to identify: capacity issues because of shortages in human resources, structural constraints, and patient access barriers including diversity and healthcare disparity challenges; recommendations to address challenges; and stakeholders to engage. This report details the deliberations and recommendations of a national symposium, "Hematopoietic Cell Transplantation in 2020: A Health Care Resource and Infrastructure Assessment," held in September 2010., (Copyright © 2012 American Society for Blood and Marrow Transplantation.

- Abstract
Autologous hematopoietic stem cell transplantation (HSCT) is a potentially curative therapeutic approach for various malignant hematologic and lymphoid diseases. Hematopoietic stem cells (HSCs) may be collected from the blood or the bone marrow. HSCs are capable of self-renewal and give rise to progenitor cells, multipotent cells that differentiate and proliferate into the mature cells of the blood and immune system. HSCs and progenitor cells are released from the bone marrow into the peripheral blood through a process called mobilization. HSCs then are collected from the blood in a process called apheresis and cryopreserved for administration following the high-dose preparative regimen. This article reviews stem cell biology, current mobilization strategies, use of novel mobilization agents, and nursing care of patients during the mobilization phase of autologous HSCT. Understanding the biology and process of HSC mobilization is critical for transplantation nurses to deliver and coordinate care during this complex phase of autologous HSCT.

- Abstract
Purpose/objectives: To examine practice variation in hematopoietic stem cell transplantation (HSCT) nursing and to identify the gap between recommended standards of practice and actual practice across settings. Additional practices relevant to HSCT nursing also were explored., Research Approach: Cross-sectional, descriptive survey., Setting: National and international cancer centers., Participants: A convenience sample was obtained from the 2006 Oncology Nursing Society Blood and Marrow Stem Cell Transplant Special Interest Group membership list (N = 205). Most participants were women (94%) with a median age of 45 years. The primary role was bedside nurse (46%), with an adult-only population (78%) in an academic (84%), inpatient (68%-88%) center. 39 (94%) U.S. states and 7 (6%) non-U.S. countries were represented., Methodologic Approach: Survey development was guided by Dillman Mail and Internet survey design. Electronic questionnaires were conducted with Zoomerang Market Tools., Main Research Variables: Infection control practices across bone marrow transplantation settings., Findings: Descriptive statistics revealed minimal practice variation regarding infection control across transplantation types or conditioning regimens. Practices regarding implementation of restrictions on patients' hygiene, diet, and social interactions varied by phase of transplantation, with the greatest variations occurring during the post-transplantation phase. Sixty-two percent of respondents reported using published guidelines; 72% reported using organization-specific policies., Conclusions: Although published standards are under consideration, practice variation exists across transplantation centers. Whether the variation is caused by a lack of compliance with published guidelines or by the poor delineation of details for providers to translate the guidelines into practice is not known., Interpretation: Identifying gaps in the literature and inconsistencies in HSCT practices is an important first step in designing evidence-based projects that can be used to standardize practice and link best practices to improved patient outcomes.

- Abstract
Background: Catheter-associated infections markedly contribute to treatment failure in peritoneal dialysis (PD) patients. There is much controversy surrounding prophylactic strategies to prevent these infections., Methods: In this nationwide multicenter study we analyzed strategies to prevent catheter-associated infections as performed in Austrian PD centers in 2006. A questionnaire was sent to all 23 PD centers in Austria., Results: Ten different catheter models were used in the 332 patients being treated in the 23 Austrian PD centers. Systemic antibiotics prior to catheter placement were given by 17 of the 23 PD centers (glycopeptides, n = 7; cephalosporins, n = 10). Nasal swabs were taken preoperatively by 17 PD centers; nasal Staphylococcus aureus carriers were treated prophylactically with mupirocin cream in 15 of these centers. Dressing change was routinely performed in 318 of 332 chronic PD patients (nonocclusive film dressing, n = 58; gauze dressing, n = 260). Disinfectants for chronic exit-site care included povidone iodine (n = 155), sodium hypochlorite (n = 31), povidone iodine + sodium hypochlorite together (n = 102), and octenidine dihydrochloride/phenoxyethanol (n = 17). Water + non-disinfectant soap or 0.9% sodium chloride was administered as a cleansing agent to the exit site by 27 patients. Routine S. aureus screening (nasal and/or exit-site swabs) in chronic PD patients was performed in 12 PD centers; carriers were treated with mupirocin cream in 11 of these centers. Dialysis staff members were screened for S. aureus in 8 PD centers and spouses were screened for S. aureus in 5 PD centers. The overall exit-site infection rate was 1 episode/43.9 patient-months, tunnel infection rate was 1 episode/88.9 patient-months, and peritonitis rate was 1 episode/51.0 patient-months. Patients of centers that have installed a prophylaxis protocol for treating S. aureus carriers had lower mean infection rates compared with those not using such a protocol., Conclusion: Various individual prophylactic strategies are used to prevent catheter-associated infections in Austrian PD centers. Infection rates are within the range reported in the literature. There is still scope for improvement in some centers (e.g., by establishing a prophylaxis protocol).
