Abstract
Natural organic matter (NOM) can contribute to arsenic (As) mobilization as an electron donor for microbially-mediated reductive dissolution of As-bearing Fe(III) (oxyhydr)oxides. However, to investigate this process, instead of using NOM, most laboratory studies used simple fatty acids or sugars, often at relatively high concentrations. To investigate the role of relevant C sources, we therefore extracted in situ NOM from the upper aquitard (clayey silt) and lower sandy aquifer sediments in Van Phuc (Hanoi area, Vietnam), characterized its composition, and used 100-day microcosm experiments to determine the effect of in situ OM on Fe(III) mineral reduction, As mobilization, and microbial community composition. We found that OM extracted from the clayey silt (OMC) aquitard resembles young, not fully degraded plant-related material, while OM from the sandy sediments (OMS) is more bioavailable and related to microbial biomass. Although all microcosms were amended with the same amount of C (12 mg C/L), the extent of Fe(III) reduction after 100 days was the highest with acetate/lactate (43 ± 3.5% of total Fe present in the sediments) followed by OMS (28 ± 0.3%) and OMC (19 ± 0.8%). Initial Fe(III) reduction rates were also higher with acetate/lactate (0.53 mg Fe(II) in 6 days) than with OMS and OMC (0.18 and 0.08 mg Fe(II) in 6 days, respectively). Although initially more dissolved As was detected in the acetate/lactate setups, after 100 days, higher concentrations of As (8.3 ± 0.3 and 8.8 ± 0.8 μg As/L) were reached in OMC and OMS, respectively, compared to acetate/lactate-amended setups (6.3 ± 0.7 μg As/L). 16S rRNA amplicon sequence analyses revealed that acetate/lactate mainly enriched Geobacter, while in situ OM supported growth and activity of a more diverse microbial community. Our results suggest that although the in situ NOM is less efficient in stimulating microbial Fe(III) reduction than highly bioavailable acetate/lactate, it ultimately has the potential to mobilize the same amount or even more As.

Abstract
We present the first study to examine the year-round distribution, activity patterns, and habitat use of one of New Zealand’s most common seabirds, the fluttering shearwater (Puffinus gavia). Seven adults from Burgess Island, in the Hauraki Gulf, and one individual from Long Island, in the Marlborough Sounds, were successfully tracked with combined light-saltwater immersion loggers for one to three years. Our tracking data confirms that fluttering shearwaters employ different overwintering dispersal strategies, where three out of eight individuals, for at least one of the three years when they were being tracked, crossed the Tasman Sea to forage over coastal waters along eastern Tasmania and southeastern Australia. Resident birds stayed confined to waters of northern and central New Zealand year-round. Although birds frequently foraged over pelagic shelf waters, the majority of tracking locations were found over shallow waters close to the coast. All birds foraged predominantly in daylight and frequently visited the colony at night throughout the year. We found no significant inter-seasonal differences in the activity patterns, or between migratory and resident individuals. Although further studies of inter-colony variation in different age groups will be necessary, this study presents novel insights into year-round distribution, activity patterns and habitat use of the fluttering shearwater, which provide valuable baseline information for conservation as well as for further ecological studies.

WASTE MANAGEMENT (NEW YORK, N.Y.) 2019; 88:56-70.

Abstract
Offensive human waste refers to non-hazardous waste that contains body fluids from non-infectious humans, comprised of post-consumer Absorbent Hygiene Products (AHPs), swabs, dressings, bedding, gloves, and other materials. While this waste category requires more stringent handling, storage and disposal measures than general waste, its non-hazardous nature suggests that there are opportunities for waste valorisation. An inventory of 200 offensive human waste bags collected from various healthcare institutions in South-Eastern England show that about 76% of the waste is comprised of AHPs, most of which are adult incontinence pads and child nappies. Mixed plastics comprised of predominantly HDPE represent 9% of the waste. To evaluate the potentials for offensive human waste valorisation, small-scale separation tests involving artificially-soiled nappies and associated mixed plastic packaging wastes have been performed. Findings suggest that about 50% of the total superabsorbent polymer is recoverable from fluff pulp fractions, recoveries of which are unaffected by the presence of ionic species typically present in human waste. On the other hand, recovery of mixed plastic packaging is more challenging. Overall, however, findings suggest that viable AHP recycling is possible if recyclate materials are targeted towards non-food related markets outlets such as the construction and land remediation sectors.

Abstract
Aims: To describe the PH Mobile Surgical Outreach (MSO) model of care delivery for women with GF and to present data highlighting the program’s scope and clinical impact in 2011-2017.
Methods: PH created the MSO program to deliver health services to women with genital fistula (GF) living in remote areas in DRC. The MSO model facilitates reintegration through community education about GF, leveraging local staff in all aspects of care. Outreach trips are organized annually/bi-annually per site, depending on case volume and funding. Site selection is a two-step process: (1) identification of accessible, strategically located hospitals; (2) initial site visit and readiness assessment. This paper presents 2011-2017 MSO activities, including geographic scope, patient and provider outcomes.
Results: The MSO team has worked with 43 clinic sites across 12 provinces. Since 2011, they have conducted 77 site visits and provided surgical care for 2,017 women. Table1 summarizes surgeries conducted annually by province, 2011-2017.Table 2 provides a clinical snapshot of 2017 case mix.
Conclusions: The MSO model demonstrates feasibility and indicates program successes for capacity-building in skilled medico-surgical care and enhancing community awareness of GF. Training serves to improve local provider skills, strengthens health workforce and offers scalable, sustainable solutions to prevention and treatment.

Abstract
BACKGROUND AND PURPOSE Radiodermatitis is a well-known toxicity of radiotherapy and barrier film has been shown to reduce the severity of radiodermatitis. We have validated prior findings in a Danish cohort, using a similar barrier film and patient reported outcomes. MATERIALS AND METHODS 101 Danish breast cancer patients were included at three radiotherapy centres. Based on randomization either the lateral or medial part of their chest was covered by Mepitel film; making the patients their own control. The primary endpoint was patient reported symptoms and experience. A secondary endpoint was radiotherapy staff evaluation of dermatitis. RESULTS Within the skin area covered by film, the patients reported a statistical significant lower level of pain (p < .001), itching (p = 0.005), burning sensation (p = 0.005) as well as edema (p = 0.017) and reduced sensitivity (p < .001). Most patients (76%) would have preferred film on the entire treatment area (p < 0.001) and Mepitel Film as a standard treatment option (84%) (p < 0.001). Patients treated after mastectomy had a significantly lower severity of radiation-induced dermatitis with film at the end of RT compared to standard care (p = 0.005). However, in the blinded staff evaluation, no significant differences were found at follow-up. CONCLUSIONS Patients reported reduced symptoms from the skin with Mepitel Film and the majority would have preferred film as a standard offer to cover their entire treatment area. Especially women treated after mastectomy had a significantly lower level of radiodermatitis and preferred the film over standard care.

Abstract
Neurofilament (NFL) proteins have recently been found to play unique roles in synapses. NFL is known to interact with the GluN1 subunit of N-methyl-D-aspartic acid (NMDAR) and be reduced in schizophrenia though functional consequences are unknown. Here we investigated whether the interaction of NFL with GluN1 modulates synaptic transmission and schizophrenia-associated behaviors. The interaction of NFL with GluN1 was assessed by means of molecular, pharmacological, electrophysiological, magnetic resonance spectroscopy (MRS), and schizophrenia-associated behavior analyses. NFL deficits cause an NMDAR hypofunction phenotype including abnormal hippocampal function, as seen in schizophrenia. NFL-/- deletion in mice reduces dendritic spines and GluN1 protein levels, elevates ubiquitin-dependent turnover of GluN1 and hippocampal glutamate measured by MRS, and depresses hippocampal long-term potentiation. NMDAR-related behaviors are also impaired, including pup retrieval, spatial and social memory, prepulse inhibition, night-time activity, and response to NMDAR antagonist, whereas motor deficits are minimal. Importantly, partially lowering NFL in NFL+/- mice to levels seen regionally in schizophrenia, induced similar but milder NMDAR-related synaptic and behavioral deficits. Our findings support an emerging view that central nervous system neurofilament subunits including NFL in the present report, serve distinctive, critical roles in synapses relevant to neuropsychiatric diseases.

Abstract
Clinical tools to identify individuals with unstable atherosclerotic lesions are required to improve prevention of myocardial infarction and ischemic stroke. Here, a systems-based analysis of atherosclerotic plaques and plasma from patients undergoing carotid endarterectomy for stroke prevention was used to identify molecular signatures with a causal relationship to disease. Local plasma collected in the lesion proximity following clamping prior to arteriotomy was profiled together with matched peripheral plasma. This translational workflow identified biliverdin reductase B as a novel marker of intraplaque hemorrhage and unstable carotid atherosclerosis, which should be investigated as a potential predictive biomarker for cardiovascular events in larger cohorts.

Abstract
BACKGROUND Rosacea diagnosis and classification have evolved since the 2002 National Rosacea Society expert panel subtype approach. Several working groups are now aligned to a more patient-centric phenotype approach, based on an individual's presenting signs and symptoms. However, subtyping is still commonplace across the field and an integrated strategy is required to ensure widespread progression to the phenotype approach. OBJECTIVES To provide practical recommendations that facilitate adoption of a phenotype approach across the rosacea field. METHODS A review of the literature and consolidation of rosacea expert experience. RESULTS We identify challenges to implementing a phenotype approach in rosacea and offer practical recommendations to overcome them across clinical practice, interventional research, epidemiological research and basic science. CONCLUSIONS These practical recommendations are intended to indicate the next steps in the progression from subtyping to a phenotype approach in rosacea, with the goals of improving our understanding of the disease, facilitating treatment developments and ultimately improving care for patients with rosacea.

Abstract
Land plants are engaged in intricate communities with soil bacteria and fungi indispensable for plant survival and growth. The plant-microbial interactions are largely governed by specific metabolites. We employed a combination of lipid-fingerprinting, enzyme activity assays, high-throughput DNA sequencing and isolation of cultivable microorganisms to uncover the dynamics of the bacterial and fungal community structures in the soil after exposure to isothiocyanates (ITC) obtained from rapeseed glucosinolates. Rapeseed-derived ITCs, including the cyclic, stable goitrin, are secondary metabolites with strong allelopathic affects against other plants, fungi and nematodes, and in addition can represent a health risk for human and animals. However, the effects of ITC application on the different bacterial and fungal organisms in soil are not known in detail. ITCs diminished the diversity of bacteria and fungi. After exposure, only few bacterial taxa of the Gammaproteobacteria, Bacteriodetes and Acidobacteria proliferated while Trichosporon (Zygomycota) dominated the fungal soil community. Many surviving microorganisms in ITC-treated soil where previously shown to harbor plant growth promoting properties. Cultivable fungi and bacteria were isolated from treated soils. A large number of cultivable microbial strains was capable of mobilizing soluble phosphate from insoluble calcium phosphate, and their application to Arabidopsis plants resulted in increased biomass production, thus revealing growth promoting activities. Therefore, inclusion of rapeseed-derived glucosinolates during biofumigation causes losses of microbiota, but also results in enrichment with ITC-tolerant plant microorganisms, a number of which show growth promoting activities, suggesting that Brassicaceae plants can shape soil microbiota community structure favoring bacteria and fungi beneficial for Brassica plants.

Abstract
AIM To study the influence of patient characteristics and unit ergonomics and human factors on the time to initiation of CPR. METHODS A single center study of children, 0 to 21 years old, admitted to an ICU who experienced cardiopulmonary arrest (CPA) requiring >1 min of chest compressions. Time of CPA was determined by analysis of continuous ECG, plethysmography, arterial blood pressure, and end-tidal CO2 (EtCO2) waveforms. Initiation of CPR was identified by the onset of cyclic artifact in the ECG waveform. Patient characteristics and unit ergonomics and human factors were examined including CPA cause, identification on the High-Risk Checklist (HRC), existing monitoring, ICU type, time of day, nursing shift change, and outcome. RESULTS The median time from CPA to initiation of CPR was 50.5 s (IQR 26.5 to 127.5) in 36 CPAs. Forty-seven percent of patients experienced time from CPA to initiation of CPR of >1 min. There was no difference in CPA cause, ICU type, time of day, or nursing shift change. CONCLUSION Nearly half of pediatric patients who experienced CPA in an ICU setting did not meet AHA guidelines for early initiation of CPR. This is an opportunity to study the recognition phase of CPA using continuous monitoring data with the aim of improving the understanding of and factors contributing to delays in initiation of CPR.

Abstract
AbstractThe computer-based patient record (CPR) is a tool likely to have great impact on the practice of medicine in the years to come. Yet, clinical settings with a fully integrated CPR are hard to find. This paper takes a sociological look at the attempts to construe and introduce CPRs. It is argued that part of the current trouble in getting these tools to work lies in the model of medical work that is inscribed in many (attempted) CPRs. A more sociological perspective on medical work should be able to offer points of departure for the construction of systems wh ich might fit the needs of health care workers better. Based on participatory observation, the paper outlines what it is medical work comes down to from a sociological perspective, and how the medical record figures in this work. Finally, some consequences this depiction has for current discussions on and (proposed) implementations of CPRs are described.

Abstract
Summary
Objectives: This article aims to search for the way patient care information systems can be most fruitfully put to work in health care.
Methods: Given the calls for improved health care quality, there is a need for IT’s coordination capacities in health care. Yet IT’s track record in this area is less than many expected. Moreover, many argue that the nature of health care work sets natural limits to the possibilities of IT to revolutionize this work. Starting with an analysis of the paper record, this article explores the way IT and professional work can be interrelated synergistically.
Results: Two principles are discussed: 1) The key to a fruitful operation of IT in health care work lies in the unraveling of the care process, and the redistribution of tasks between professionals and the IT application. 2) Professionals should be given the skills and resources to adapt the IT application’s demands to the needs of their work practices.
Conclusion: IT can bring true process support to health care when taking the two principles discussed here into account.

Abstract
SummaryThe importance of the social sciences for medical informatics is increasingly recognized. As ICT requires interaction with people and thereby inevitably affects them, understanding ICT requires a focus on the interrelation between technology and its social environment. Socio-technical approaches increase our understanding of how ICT applications are developed, introduced and become a part of social practices. Sociotechnical approaches share several starting points: 1) they see health care work as a social, ‘real life’ phenomenon, which may seem ‘messy’ at first, but which is guided by a practical rationality that can only be overlooked at a high price (i.e. failed systems). 2) They see technological innovation as a social process, in which organizations are deeply affected. 3) Through in-depth, formative evaluation, they can help improve system design and implementation.

Abstract
Summary
Objective: The aim of this paper is twofold. First, we describe two important dimensions of patient care information systems (PCIS) evaluation: the domain of evaluation and the different phases of the PCIS implementation. Second, we claim that, though Randomized Controlled Trials (RCTs) are often still seen as the standard approach, this type of design hardly generates relevant information for the organizational decision maker.
Method: Interpretive study of evaluation literature. Results and Conclusions: The field of evaluation is scattered and the types of questions that can be asked and methods that can be used seem infinite and badly demarcated. Different stakeholders, moreover, often have different priorities in evaluating ICT. The most important reason for the lack of relevance of RCTs is that they are ill suited for investigating why and how a PCIS is being used, or not, and what the (often unplanned) effects and consequences are. Subsequently, our aim is to contribute to the discussion about the viability of qualitative versus quantitative methods in PCIS evaluation, by arguing for a specific integration of quantitative and qualitative research methods. The joint utilization of these methods, we claim, yields the richest results.

The transcribed texts and implementation documents were analyzed for relevant concepts.The transcripts and field notes were analyzed using a heuristic success and failure model with medical work as the primary focus.
Results:
Occasions that determined the outcome of the implementation were classified according to factors that may influence the success or failure of implementing systems.
Conclusions:
The themes and patterns that emerged from the data helped validate the concept of medical work as the primary focus of our analysis model; in addition the concept of a support base necessary to accept changes in medical work that result from introducing CPOE may help to understand the different implementation outcomes.

Abstract
AIMS To report results from and explore use of a multicentre, parallel-group, unblinded, randomized controlled trial testing the effectiveness in terms of well-being and diabetes management of a person-centred, web-based support programme for women with Type 1 diabetes, in pregnancy and postpartum. METHODS Between 2011 and 2014, 174 pregnant women with Type 1 diabetes were randomly allocated (1:1) to web-based support and standard care (intervention group, n=83), or standard care (control group, n=91). The web-based support consisted of evidence-based information; a self-care diary for monitoring of daily activities; and peer support in a discussion forum. The primary outcomes (mean difference, measured at 6 months after childbirth) were well-being and diabetes management. RESULTS No differences were found with regard to the primary outcome measure scores for general well-being [1.04 (95% CI -1.28 to 3.37); P=0.68] and self-efficacy of diabetes management [0.08 (95% CI -0.12 to 0.28); P= 0.75], after adjustment for baseline differences in the insulin administration method, nor with regard to the secondary outcome measures. CONCLUSIONS At 6 months after childbirth, the web-based support plus standard care was not superior to standard care in terms of general well-being or self-efficacy of diabetes management. This might be explained by the low number of participants who had a high activity level. Few simultaneously active participants in the web-based programme and stressors in motherhood and diabetes postpartum were the main barriers to its use. Further intervention studies that offer web-based support are needed, with lessons learned from the present study. (Clinicaltrials.gov identification number: NCT015665824).

Abstract
Summary
Objectives:
Intra-organizational communication is mostly interpersonal. Synchronous interruptive communication is recognized as aprimary source of inefficiency anderror in healthcare, and there is much potential for information and communication technology (ICT) to improve such communication. As recently suggested, however, due to communication failures ICT can also compound medical errors. In this paper we analyze factors that restrict the role of ICT in improving interpersonal healthcare communication and suggest solutions. Methods: We critically analyzed the literature from a selection of diverse scientific disciplines. These were related to interpersonal communication, tothe role and place of standardization and computerization in its improvement, and to reducing medical errors.
Results:
Four possible scenarios were defined on how ICT can serve healthcare communication. Two differing conceptual frameworks about communication in health-care were discussed. Considering “information space” as apart of “communication space ” allows the recognition and control of the source of the semantic gaps in conventional standardization and an enhancement of the role of ICT in improving intra-organizational communication. Moreover, cognitive, social, and organizational dimensions of complexity in interpersonal communication can be managed. Three approaches to control the variability in those dimensions and to promote therole of ICT in intra-organizational communication were discussed.
Conclusion:
A multi-dimensional approach is required to promote the role of ICT in intra-organizational communication in healthcare. Parallel to conventional standardization, atleast three dimensions need to be addressed: controlling the effect of the social context, developing standard information processing skills, and most importantly, controlling variations in care practices’ performance.
