Nutritional and Post-Transplantation Outcomes of Enteral versus Parenteral Nutrition in Pediatric Hematopoietic Stem Cell Transplantation: A Systematic Review of Randomized and Nonrandomized Studies
Hematopoietic stem cell transplantation (HSCT) involves the administration of chemotherapy followed by the infusion of donor stem cells. After treatment, children can consequently experience nausea, vomiting, diarrhea, anorexia, and mucositis, which negatively impact oral intake, leading to rapid deterioration in nutritional status and risk of malnutrition. Nutrition support therefore becomes necessary to circumvent these adverse effects. This has traditionally been provided via parenteral nutrition (PN), but pediatric evidence is increasingly advocating enteral nutrition (EN) as a preferential alternative. The objective of this review is to determine the efficacy of any forms of EN versus PN provided during admission to children aged ≤ 18 years undergoing HSCT. Primary outcomes considered efficacy in relation to various nutritional parameters, and secondary outcomes included a range of post-transplantation parameters. Data sources included English and non-English articles from the start date of MEDLINE, EMBASE, AMED, CINAHL and Cochrane Controlled Trials register, up to July 2018. Key journals were also hand searched, reference lists scanned, clinical experts contacted, and gray literature searched using EThOS and Open Grey. Randomized and observational studies comparing any forms of EN versus PN in children aged ≤ 18 years undergoing HSCT investigating nutritional or post-transplantation outcomes were eligible. Data were extracted from included studies using a custom extraction form that had previously been piloted. Because included studies were observational, risk of bias was assessed using Risk of Bias in Non-randomised Studies of Interventions. Because only a small number of heterogenous studies reporting a wide range of differently defined outcomes were included, meta-analyses were not performed and data were presented in narrative form. Conflicting results in favor of either method of nutrition support or no difference between methods were seen for duration of interventions, nutritional intakes, biochemical and anthropometric changes, mortality, infections, length of admission, and neutrophil engraftment. EN may provide favorable benefits over PN regarding acute graft-versus-host-disease (aGVHD) and platelet engraftment. A paucity of studies was found investigating the question posed by this review. Included studies were clinically heterogenous regarding populations, interventions, and outcomes, at moderate to serious risk of bias due to the absence of randomization, confounding parameters, statistical control, retrospective designs, and participant selection. Some studies were more than 15 years old. Despite the limited number and poor quality of identified studies, results support the growing body of pediatric evidence that EN is feasible during HSCT. Similar differences regarding many nutritional and post-transplantation outcomes were seen in both forms of nutrition support, but EN could provide benefits above PN including reduced incidence of aGVHD and faster platelet engraftment

Barriers Impeding Early Detection of Breast Cancer in Iraq: A Critical Analysis
Breast cancer (BC) patients in Iraq tend to be diagnosed at advanced stages and among younger age groups compared to their counterparts in high-income countries, which has led to a higher BC related mortality rate in Iraq. The aim of this paper is to identify the barriers impeding early detection of BC among Iraqi women. The Social-Ecological Model and the knowledge, attitudes and practices framework were used for the analysis. Gaps in awareness of BC-related facts are still present among Iraqi women which are negatively affecting their attitudes and practices towards the early detection of the disease. Women highlighted their concerns regarding losing family support if they were diagnosed with BC. Those living in rural areas and internally displaced populations face difficulties in reaching specialised health centres. There are deficiencies in the required human resources and infrastructure available to the breast cancer early detection programme as it lacks direct budget allocation from the government. Other obstacles include poor implementation of the national protocol guidelines and weak monitoring and evaluation systems. There is an urgent need to adopt comprehensive national protocol guidelines for early detection of BC in Iraq, in line with recommendations of the Breast Health Global Initiative for LMICs
Unsupervised morphological segmentation in a language with reduplication
We present an extension of the Morfessor Base line model of unsupervised morphological seg mentation (Creutz and Lagus, 2007) that in corporates abstract templates for reduplication,
a typologically common but computationally
underaddressed process. Through a detailed in vestigation that applies the model to Maori, the ¯
Indigenous language of Aotearoa New Zealand,
we show that incorporating templates improves
Morfessor’s ability to identify instances of redu plication, and does so most when there are
multiple minimally-overlapping templates. We
present an error analysis that reveals important
factors to consider when applying the extended
model and suggests useful future directions

Variations in the uptake of telemental health technologies in community and crisis mental health services during the early pandemic: a survey of mental health professionals in the UK
Background
One of the many challenges faced by mental health services during the COVID-19 pandemic was how to deliver care during lockdown. In community and crisis services, this often meant rapidly adopting or expanding the use of telemental health technologies, including phone and video calls. The aim of this study is to explore variations in use and report staff views of such technologies during the early stages of the pandemic. The primary analysis compared rates of use between professions, demographic groups, genders, regions, and crisis and community services.
Methods
We used data from an online survey conducted by the Mental Health Policy Research Unit in Spring 2020 regarding the impact of the pandemic on mental healthcare in the United Kingdom. We included quantitative data from all professional groups working in community or crisis services providing care to working age adults, including general and specialist services. Our outcome of interest was the percentage of clients whom clinicians primarily interacted with via videocall. We also collected demographics and professional characteristics such as the type of mental health service respondents worked in. In addition, we explored respondents’ views and experiences of telemental health as a medium for providing care.
Results
978 participants were included in the primary analysis (834 provided outcome data for community services, 193 for crisis services). In community services, virtually all staff reported stopping some or all face-to-face appointments following the onset of the pandemic, with a large majority using video or phone call appointments where possible instead. Telemental health use was higher in community than in crisis services, and amongst professionals who mainly provided psychotherapy or peer support than in other groups. There was also evidence of use being lower in regions in Northern England, Scotland, and Wales than elsewhere. There was no evidence of an association with staff gender, age, or ethnicity. Staff were generally positive about telemental health and intended to make more use of technologies following the pandemic. However, significant barriers to its use were also reported, often involving skills and available infrastructure.
Conclusions
Despite its rapid implementation, telemental health was viewed positively by clinicians who saw it as an effective alternative to face-to-face appointments in some contexts, including during the pandemic. However, adoption of the technology also has the potential to exacerbate existing or create new inequalities without effective management of training and infrastructure needs
Non-Māori-speaking New Zealanders have a Māori proto-lexicon
We investigate implicit vocabulary learning by adults who are exposed to a language in their ambient environment. Most New Zealanders do not speak Māori, yet are exposed to it throughout their lifetime. We show that this exposure leads to a large proto-lexicon – implicit knowledge of the existence of words and sub-word units without any associated meaning. Despite not explicitly knowing many Māori words, non-Māori-speaking New Zealanders are able to access this proto-lexicon to distinguish Māori words from Māori-like nonwords. What's more, they are able to generalize over the proto-lexicon to generate sophisticated phonotactic knowledge, which lets them evaluate the well-formedness of Māori-like nonwords just as well as fluent Māori speakers
Development of a conceptual framework to guide description and evaluation of social interventions for people with serious mental health conditions
People with serious mental health conditions face social exclusion and have poorer social outcomes compared to the general population in several areas of life. Social exclusion also negatively impacts mental health. Promising models of support to improve social outcomes for people with serious mental health conditions have been described in the literature and proliferate in practice, but typologies of support are not clearly established and a robust evidence base for effective approaches is lacking in many areas. We conducted a scoping review of relevant literature and consulted with experts in the field to identify models to improve social circumstances across eight life domains, with the aim of developing a conceptual framework to distinguish the main broad approaches to improving the social circumstances of people with serious mental health conditions. We also sought to explore which approaches have been used in models within each life domain. This work was conducted in collaboration with a group of expert stakeholders, including people with lived experience of accessing mental health services. We developed a conceptual framework which distinguishes sources and types of support, allowing description of complex interventions to improve the social circumstances of people with serious mental health problems, and providing a framework to guide future service development and evaluation
Early impacts of the COVID-19 pandemic on mental health care and on people with mental health conditions: framework synthesis of international experiences and responses
PURPOSE: The COVID-19 pandemic has many potential impacts on people with mental health conditions and on mental health care, including direct consequences of infection, effects of infection control measures and subsequent societal changes. We aimed to map early impacts of the pandemic on people with pre-existing mental health conditions and services they use, and to identify individual and service-level strategies adopted to manage these. METHODS: We searched for relevant material in the public domain published before 30 April 2020, including papers in scientific and professional journals, published first person accounts, media articles, and publications by governments, charities and professional associations. Search languages were English, French, German, Italian, Spanish, and Mandarin Chinese. Relevant content was retrieved and summarised via a rapid qualitative framework synthesis approach. RESULTS: We found 872 eligible sources from 28 countries. Most documented observations and experiences rather than reporting research data. We found many reports of deteriorations in symptoms, and of impacts of loneliness and social isolation and of lack of access to services and resources, but sometimes also of resilience, effective self-management and peer support. Immediate service challenges related to controlling infection, especially in inpatient and residential settings, and establishing remote working, especially in the community. We summarise reports of swiftly implemented adaptations and innovations, but also of pressing ethical challenges and concerns for the future. CONCLUSION: Our analysis captures the range of stakeholder perspectives and experiences publicly reported in the early stages of the COVID-19 pandemic in several countries. We identify potential foci for service planning and research
Implementation, adoption and perceptions of telemental health during the COVID-19 pandemic: a systematic review
BACKGROUND: Early in 2020, mental health services had to rapidly shift from face-to-face models of care to delivering the majority of treatments remotely (by video or phone call or occasionally messaging) due to the COVID-19 pandemic. This resulted in several challenges for staff and patients, but also in benefits such as convenience or increased access for people with impaired mobility or in rural areas. There is a need to understand the extent and impacts of telemental health implementation, and barriers and facilitators to its effective and acceptable use. This is relevant both to future emergency adoption of telemental health, and to debates on its future use in routine mental health care. OBJECTIVE: To investigate the adoption and impacts of telemental health approaches during the COVID-19 Pandemic, and facilitators and barriers to optimal implementation. METHODS: Four databases (PubMed, PsycINFO, CINAHL and Web of Science) were searched for primary research relating to remote working, mental health care, and the COVID-19 pandemic. Preprint servers were also searched. Results of studies were synthesised using framework synthesis. RESULTS: A total of 77 papers met our inclusion criteria. In most studies, the majority of contacts could be transferred to a remote form during the pandemic, and good acceptability to service users and clinicians tended to be reported, at least where the alternative to remote contacts was interrupting care. However, a range of impediments to dealing optimal care by this means were also identified. CONCLUSIONS: Implementation of telemental health allowed some continuing support to the majority of service users during the COVID-19 pandemic and has value in an emergency situation. However, not all service users can be reached by this means, and better evidence is now needed on long-term impacts on therapeutic relationships and quality of care, and on impacts on groups at risk of digital exclusion and how to mitigate these.
