RESUMO

BACKGROUND: Randomised controlled trials are often beset by problems with poor recruitment and retention. Information to support decisions on trial participation is usually provided as printed participant information sheets (PIS), which are often long, technical, and unappealing. Multimedia information (MMI), including animations and videos, may be a valuable alternative or complement to a PIS. The Trials Engagement in Children and Adolescents (TRECA) study compared MMI to PIS to investigate the effects on participant recruitment, retention, and quality of decision-making. METHODS: We undertook six SWATs (Study Within A Trial) within a series of host trials recruiting children and young people. Potential participants in the host trials were randomly allocated to receive MMI-only, PIS-only, or combined MMI + PIS. We recorded the rates of recruitment and retention (varying between 6 and 26 weeks post-randomisation) in each host trial. Potential participants approached about each host trial were asked to complete a nine-item Decision-Making Questionnaire (DMQ) to indicate their evaluation of the information and their reasons for participation/non-participation. Odds ratios were calculated and combined in a meta-analysis. RESULTS: Data from 3/6 SWATs for which it was possible were combined in a meta-analysis (n = 1758). Potential participants allocated to MMI-only were more likely to be recruited to the host trial than those allocated to PIS-only (OR 1.54; 95% CI 1.05, 2.28; p = 0.03). Those allocated to combined MMI + PIS compared to PIS-only were no more likely to be recruited to the host trial (OR = 0.89; 95% CI 0.53, 1.50; p = 0.67). Providing MMI rather than PIS did not impact on DMQ scores. Once children and young people had been recruited to host trials, their trial retention rates did not differ according to intervention allocation. CONCLUSIONS: Providing MMI-only increased the trial recruitment rate compared to PIS-only but did not affect DMQ scores. Combined MMI + PIS instead of PIS had no effect on recruitment or retention. MMIs are a useful tool for trial recruitment in children and young people, and they could reduce trial recruitment periods.

RESUMO

BACKGROUND: Evidence regarding the effects of infant feeding type (exclusive breastfeeding compared with exclusive formula feeding) on the gut microbiota and how it impacts infant growth status is limited. OBJECTIVES: The primary objective was to compare gut microbiota by feeding type and characterize the associations between gut microbiota and infant growth status. METHODS: Stool samples from healthy, full-term infants (4-5 mo-old) who were either exclusively breastfed (BF) or exclusively formula-fed (FF) in Denver, CO, United States were collected, and fecal 16S ribosomal ribonucleic acid gene-based profiling was conducted. Length and weight were measured at the time of stool collection. Length-for-age z-score, weight-for-age z-scores (WAZ), and weight-for-length z-scores were calculated based on the World Health Organization standards. Associations between gut microbial taxa and anthropometric z-scores were assessed by Spearman's rank correlation test. RESULTS: A total of 115 infants (BF n = 54; FF n = 61) were included in this study. Feeding type (BF compared with FF) was the most significant tested variable on gut microbiota composition (P < 1 × 10-6), followed by mode of delivery and race. Significant differences were observed in α-diversity, ß-diversity, and relative abundances of individual taxa between BF and FF. BF infants had lower α-diversity than FF infants. Abundances of Bifidobacterium and Lactobacillus were greater in the breastfeeding group. FF infants had a higher relative abundance of unclassified Ruminococcaceae (P < 0.001), which was associated with a higher WAZ (P < 0.001) and length-for-age z-score (P < 0.01). Lactobacillus was inversely associated with WAZ (P < 0.05). CONCLUSIONS: Feeding type is the main driver of gut microbiota differences in young infants. The gut microbiota differences based on feeding type (exclusive breast- or formula feeding) were associated with observed differences in growth status. This trial was registered at clinicaltrials.gov as NCT02142647, NCT01693406, and NCT04137445.

RESUMO

PURPOSE: Head and neck lymphedema (HNL) is common after head and neck cancer (HNC). This study aimed to explore quality of life (QoL) in patients with HNL to guide the development of a patient-reported QoL measure. METHODS: We conducted semi-structured interviews with 22 HNC survivors with HNL. Interviews explored participants' experiences of living with HNL. Analysis of interview transcripts drew on qualitative content analysis to ensure themes were grounded in patient experience. RESULTS: Two main themes were established: "I want to live my life" and "It was like things were short-circuited." These themes encompassed the substantial disruption patients attributed to the HNL and their desire to normalize life. CONCLUSIONS: Understanding the impact of HNL on individual patients may be critical to optimizing treatment strategies to improve the physical burden of HNL and QoL. This study provides the framework for developing a patient-reported HNL QoL measure. IMPLICATIONS FOR CANCER SURVIVORS: The development of an HNL-specific QoL measure, grounded in the patient perspective, may provide cancer care teams with a tool to better understand HNL's impact on each patient to tailor patient-centered care and optimize QoL outcomes.

RESUMO

BACKGROUND: The protein and carbohydrate composition of formula fed infants' diets in the United States (US) has not been described. The aims of this study were to characterize these dietary exposures in infant formula purchased in the US and to estimate the proportion of formula purchased which is hypoallergenic or lactose-reduced formula. METHODS: Powdered infant formula purchase data from all major physical stores in the US prior to the COVID-19 pandemic, between 2017 and 2019, were obtained from Information Resources, Inc. Protein and carbohydrate composition and scoop sizes for each formula were obtained from manufacturers. Ready to feed liquid products, products for premature infants and products for over 1 year old were not included. RESULTS: Total volumes of term formula purchased were 216 million kg of formula powder (equivalent to 1.65 billion litres) over 3 years. Intact protein formula was 67.9% of formula purchased, 26.6% was partially hydrolysed and 5.5% was hypoallergenic (5.2% extensively hydrolysed protein; 0.3% amino acid based). Soy protein formula represented 5.1% of formula purchased. Carbohydrate content overall was 52.7% lactose, 42.3% glucose polymers and 5.0% sucrose. 23.7% of formula purchased included sucrose as a carbohydrate. Of all formula purchased, 59.0% was lactose reduced, containing a non-lactose carbohydrate. Of 'standard' formula, defined as intact protein, non-thickened, cow's milk formula, 32.3% was lactose reduced. The proportion of hypoallergenic formula purchased significantly exceeded the prevalence of cow's milk protein allergy and increased over the 3-year study period from 4.9% to 7.6% of all formula sold. CONCLUSIONS: US infants are exposed to unnecessarily high levels of non-lactose carbohydrates and hypoallergenic formula, and this may represent a significant nutritional health risk.

RESUMO

BACKGROUND: Social connections have been linked to the genesis and amelioration of mental health problems and thus have potential therapeutic value. PURPOSE: To identify the current evidence base, assess risk of bias and synthesise findings on the effectiveness of social network interventions for people with mental health problems. METHODS: Electronic databases (MEDLINE, Embase, PsycINFO, CINAHL, Cochrane Library, Web of Science, Scopus) and grey literature databases were systematically searched from inception to October 2021 using free text syntax combining synonyms for 'mental health problems' and 'social network interventions'. Articles were eligible for inclusion if they reported data from randomised controlled trials on the effectiveness of interventions designed to improve social networks for adults (18+) with mental health problems. Papers were independently reviewed for inclusion with conflicts resolved through consensus. Included papers were quality assessed and data extracted and synthesized narratively. Risk of bias was assessed using the Cochrane Risk of Bias Tool. RESULTS: Nine studies randomising 2226 participants were included. Four focused on those with a diagnosis of schizophrenia or psychosis, one on major depressive disorder and four included all types of mental health diagnoses. The current evidence base is of unclear quality. However, interventions which focused on supporting social activities appear to hold the most promise for enhancing social networks. Data on cost-effectiveness and research acceptability were limited, but suggest the potential economic feasibility of and acceptability for evaluating these interventions. CONCLUSION: There is emerging evidence that social network interventions can be effective in improving social connections for people with mental health problems. However, further evaluations with robust methodological approaches are required to inform evidence-based recommendations for health services.

RESUMO

BACKGROUND: Patient and public involvement (PPI) is a cornerstone in enhancing healthcare research and delivery, including clinical guideline development. Health outcomes concern changes in the health status of an individual or population that are attributable to an intervention. Discussion of relevant health outcomes impacts the resulting clinical guidelines for practice. This study explores how the input of PPI contributors at the National Institute of Health and Care Excellence (NICE) is integrated into guideline development, particularly in relation to health outcome selection. METHODS: The study used an ethnographic methodological approach. Data comprised: observations of committee meetings, scoping workshops and training sessions, and in-depth interviews with PPI contributors, health professionals and chairs from clinical guideline development committees. Data were analysed thematically. RESULTS: PPI contributors' input in the guideline development process was often of limited scope, particularly in selecting health outcomes. Key constraints on their input included: the technical content and language of guidelines, assumed differences in the health-related priorities between PPI contributors and health professionals, and the linear timeline of the guideline development process. However, PPI contributors can influence clinical guideline development including the selection of relevant health outcomes. This was achieved through several factors and highlights the important role of the committee chair, the importance of training and support for all committee members, the use of plain language and the opportunity for all committee members to engage. CONCLUSIONS: Lay member input during the outcome selection phase of clinical guideline development is achievable, but there are challenges to overcome. Study findings identify ways that future guideline developers can support meaningful lay involvement in guideline development and health outcome selection.

RESUMO

BACKGROUND: Social integration, shared decision-making and personalised care are key elements of mental health and social care policy. Although these elements have been shown to improve service user and service-level outcomes, their translation into practice has been inconsistent and social isolation amongst service users persists. AIM: To co-adapt, with service users, carers/supporters and health professionals, a web-based social network intervention, GENIE™, for use in secondary mental health services. The intervention is designed to support social activity and preference discussions between mental healthcare professionals and service users as a means of connecting individuals to local resources. METHODS: In Phase 1 (LEARN), we completed two systematic reviews to synthesise the existing evidence relating to the i) effectiveness and ii) the implementation of social network interventions for people with mental health difficulties. We undertook semi-structured interviews with a convenience sample of 15 stakeholders previously involved in the implementation of the intervention in physical healthcare settings. Interviews were also conducted with 5 national key stakeholders in mental health (e.g., policy makers, commissioners, third sector leads) to explore wider implementation issues. In Phase 2 (ADAPT), we worked iteratively with eight service users, nine carers, six professionals/volunteers and our patient and public advisory group. We drew on a framework for experience-based co-design, consisting of a series of stakeholder consultation events, to discuss the use of the social network intervention, in mental health services. Participants also considered factors that could serve as enablers, barriers, and challenges to local implementation. RESULTS: Across the stakeholder groups there was broad agreement that the social network intervention had potential to be useful within mental health services. In terms of appropriate and effective implementation, such an intervention was predicted to work best within the care planning process, on discharge from hospital and within early intervention services. There were indications that the social connection mapping and needs assessment components were of most value and feasible to implement which points to the potential utility of a simplified version compared to the one used in this study. The training provided to facilitators was considered to be more important than their profession and there were indications that service users should be offered the opportunity to invite a carer, friend, or family member to join them in the intervention. CONCLUSION: The GENIE™ intervention has been co-adapted for use in mental health services and a plan for optimal implementation has been co-produced. The next phase of the programme of work is to design and implement a randomised controlled trial to evaluate clinical and cost effectiveness of a simplified version of the intervention.

RESUMO

BACKGROUND: Patients' participation is crucial to the success of randomized controlled trials (RCTs). However, recruiting and retaining patients in trials remain a challenge. OBJECTIVE: This study aims to describe patients' preferences for the organization of RCTs (visits on- site or remotely) and evaluate the potential impact of fulfilling preferences on their willingness to participate in a clinical trial. METHODS: This was a vignette-based survey. Vignettes were case scenarios of real clinical trials assessing pharmacological treatments. These RCTs evaluated 6 prevalent chronic diseases (ie, osteoporosis, osteoarthritis, asthma, cardiovascular diseases, diabetes, and endometriosis). Each vignette described (1) the RCT and characteristics of the treatment tested (ie, doses, administration routes) and (2) the trial procedures and different options (on-site or remotely) for how the trial was organized for informed consent, follow-up visits, and communication of results when the trial was completed. We recruited 628 participants from ComPaRe (www.compare.aphp.fr), a French e-cohort of patients with chronic diseases. The outcomes were the participants' preferences for the way the trial was organized (on-site or remotely) and their willingness to participate in the trial. RESULTS: Of the 628 participants who answered the vignettes, 491 (78.2%) were female (median age 55 years), with different chronic diseases ranging from endometriosis in 59 of 491 (12%) patients to asthma in 133 of 628 (21.2%) patients. In addition, 38 (6.1%) participants wanted to provide informed consent and all trial visits on-site, 176 (28%) wished to participate in the trial entirely remotely, and 414 (65.9%) wanted to combine remote-based and hospital-based visits. Considering the trial as a whole, when the trial was organized in a way that the patients preferred, the median (Q1-Q3) likelihood of participation in the trial was 90% (80-100) versus 60% (30-80) if the trial followed the patients' nonpreferred model. Furthermore, 256 (40.8%) patients responded to open-ended questions expressing their experience with trial participation and visits to the hospital and providing suggestions for improvement. The patients emphasized the need to personalize the way a trial is organized according to each patient's needs and conditions. CONCLUSIONS: There was a significant diversity in the participants' preferences. Most participants preferred hybrid organization involving both on-site and remote visits. Participants were more likely to participate in a trial organized according to their preferences.

RESUMO

OBJECTIVE: We sought to explore patient and parental views on treatment targets, outcome measures and study designs being considered for a future JSLE treat-to-target (T2T) study. METHODS: We conducted topic-guided, semistructured interviews with JSLE patients and parents and analysed the audio recorded interviews using thematic approaches. RESULTS: Patients and parents differed regarding symptoms they felt would be tolerable, representing 'low disease activity'. Patients often classed symptoms that they had previously experienced, were 'invisible' or had minimal disruption on their life as signs of low disease activity. Parents were more accepting of visible signs but were concerned about potential organ involvement and symptom severity. Overall, patients and parents preferred that children were entirely asymptomatic, with no ongoing treatment side effects. They regarded fatigue as particularly challenging, requiring proper monitoring using a fatigue patient-reported outcome measure. Most families felt that reducing corticosteroids would also be a good treatment target. Overall, families liked the concept of T2T, commenting that it could help to improve disease control, help structure treatment and improve communication with clinicians and treatment compliance. They were concerned that T2T might increase the frequency of hospital visits, thus impacting upon schooling, parental employment and finances. Families made suggestions on how to modify the future trial design to mitigate such effects. CONCLUSION: This study provides guidance from patients and parents on T2T targets and study designs. Complementary quantitative studies assessing the achievability and impact of different targets (e.g. lupus low disease activity state or remission) are now warranted to inform an international consensus process to develop treatment targets.

RESUMO

Breastfeeding and human milk (HM) are critically important to maternal, infant and population health. This paper summarizes the proceedings of a workshop that convened a multidisciplinary panel of researchers to identify key priorities and anticipated breakthroughs in breastfeeding and HM research, discuss perceived barriers and challenges to achieving these breakthroughs and propose a constructive action plan to maximize the impact of future research in this field. Priority research areas identified were as follows: (1) addressing low breastfeeding rates and inequities using mixed methods, community partnerships and implementation science approaches; (2) improving awareness of evidence-based benefits, challenges and complexities of breastfeeding and HM among health practitioners and the public; (3) identifying differential impacts of alternative modes of HM feeding including expressed/pumped milk, donor milk and shared milk; and (4) developing a mechanistic understanding of the health effects of breastfeeding and the contributors to HM composition and variability. Key barriers and challenges included (1) overcoming methodological limitations of epidemiological breastfeeding research and mechanistic HM research; (2) counteracting 'breastfeeding denialism' arising from negative personal breastfeeding experiences; (3) distinguishing and aligning research and advocacy efforts; and (4) managing real and perceived conflicts of interest. To advance research on breastfeeding and HM and maximize the reach and impact of this research, larger investments are needed, interdisciplinary collaboration is essential, and the scientific community must engage families and other stakeholders in research planning and knowledge translation.

RESUMO

INTRODUCTION: Providing balanced information that emphasizes clinical equipoise (i.e., uncertainty regarding the relative merits of trial interventions) and exploring patient treatment preferences can improve informed consent and trial recruitment. Within a trial comparing adjuvant radiotherapy versus active monitoring following surgical resection for an atypical meningioma (ROAM/EORTC-1308), we explored patterns in communication and reasons why health practitioners may find it challenging to convey equipoise and explore treatment preferences. MATERIALS AND METHODS: Qualitative study embedded within ROAM/EORTC-1308. Data were collected on 40 patients and 18 practitioners from 13 U.K. sites, including audio recordings of 39 patients' trial consultations, 23 patient interviews, and 18 practitioner interviews. Qualitative analysis drew on argumentation theory. RESULTS: Practitioners acknowledged the importance of the research question that the trial aimed to answer. However, they often demonstrated a lack of equipoise in consultations, particularly with eligible patients who practitioners believed to be susceptible to side effects (e.g., cognitive impairment) or inconvenienced by radiotherapy. Practitioners elicited but rarely explored patient treatment preferences, especially if a patient expressed an initial preference for active monitoring. Concerns about coercing patients, loss of practitioner agency, and time constraints influenced communication in ways that were loaded against trial participation. CONCLUSIONS: We identified several challenges that practitioners face in conveying equipoise and exploring patient treatment preferences in oncology, and particularly neuro-oncology, trials with distinct management pathways. The findings informed communication about ROAM/EORTC-1308 and will be relevant to enhancing trial communication in future oncology trials. Qualitative studies embedded within trials can address difficulties with communication, thus improving informed consent and recruitment. ROAM/EORTC-1308 RCT: ISRCTN71502099. IMPLICATIONS FOR PRACTICE: Oncology trials can be challenging to recruit to, especially those that compare treatment versus monitoring. Conveying clinical equipoise and exploring patient treatment preferences can enhance recruitment and patient understanding. This study focused on the challenges that practitioners encounter in trying to use such communication strategies and how practitioners may inadvertently impede patient recruitment and informed decision making. This article provides recommendations to support practitioners in balancing the content and presentation of trial management pathways. The results can inform training to optimize communication, especially for neuro-oncology trials and trials comparing markedly different management pathways.

RESUMO

BACKGROUND: Participation in randomized controlled trials (RCTs) may be quite demanding and could represent an important burden for patients. We aimed to explore this research burden (i.e., the psychological, physical, and financial burdens) experienced by patients through their participation in a RCT. METHODS: We conducted a systematic review of qualitative studies exploring adult patients' experiences with RCT participation. We searched MEDLINE (PubMed), CINAHL, PSYCHINFO, and Embase (search date March 2018) for eligible reports. Qualitative data coding and indexing were assisted by NVivo. The quality of reports was assessed by using the Critical Appraisal Skills Program (CASP) tool. RESULTS: We included 45 qualitative studies that involved 1732 RCT participants. Important psychological burdens were identified at every stage of the trial process. Participants reported feeling anxiety and being afraid of "being a 'guinea pig'" and described undergoing randomization and allocation to a placebo as particularly difficult resulting in disappointment, anger, and depression. Patients' follow-up and trial closure were also responsible for a wide range of psychological, physical, and financial burdens. Furthermore, factors related to burdensome impacts and consequences were discerned. These factors involved trial information, poorly organized and too-demanding follow-up, and lack of appropriate management when the patient's participation ended. Trial participation was also associated with beneficial effects such as the satisfaction of feeling "useful," gaining "a sense of control," and receiving special attention. CONCLUSIONS: Our finding provides a detailed description of research burden across the whole RCT process. Many of the burdens described could be anticipated, and some avoided in a movement toward minimally disruptive clinical research. Such an approach could improve trial recruitment and retention.

RESUMO

PURPOSE: We conducted a feasibility study to investigate the use of ketogenic diets (KDs) as an adjuvant therapy for patients with glioblastoma (GBM), investigating (i) trial feasibility; (ii) potential impacts of the trial on patients' quality of life and health; (iii) patients' perspectives of their decision-making when invited to participate in the trial and (iv) recommending improvements to optimize future phase III trials. METHODS: A single-center, prospective, randomized, pilot study (KEATING), with an embedded qualitative design. Twelve newly diagnosed patients with GBM were randomized 1:1 to modified ketogenic diet (MKD) or medium chain triglyceride ketogenic diet (MCTKD). Primary outcome was retention at three months. Semi-structured interviews were conducted with a purposive sample of patients and caregivers (n = 15). Descriptive statistics were used for quantitative outcomes and qualitative data were analyzed thematically aided by NVivo. RESULTS: KEATING achieved recruitment targets, but the recruitment rate was low (28.6%). Retention was poor; only four of 12 patients completed the three-month diet (MCTKD n = 3; MKD n = 1). Participants' decisions were intuitive and emotional; caregivers supported diet implementation and influenced the patients' decision to participate. Those who declined made a deliberative and considered decision factoring diet burden and quality of life. A three-month diet was undesirable to patients who declined and withdrew. CONCLUSION: Recruitment to a KD trial for patients with GBM is possible. A six-week intervention period is proposed for a phase III trial. The role of caregivers should not be underestimated. Future trials should optimize and adequately support the decision-making of patients.

RESUMO

BACKGROUND: Parenting programmes aim to alleviate behavioural problems in children, including conduct disorder. This study was part of a multi-phase mixed-methods project seeking to extend the reach of parenting programmes for the treatment of conduct problems through developing an evidence base to inform a personalised approach. It explored the narratives of parents of children with behavioural and conduct problems about parenting programmes to identify how such programmes could be personalised in order to extend their reach to parents and children who do not currently benefit. METHODS: Face-to-face semi-structured interviews with a purposive sample of 42 parents, who had different experiences of parenting programmes. Interviews were conversational and informed by a topic guide. Analysis of transcripts of audio-recorded interviews drew on inductive thematic approaches and was framed largely within a phenomenological perspective. RESULTS: Parents' accounts demonstrated three themes: 1) a personalised approach needs to include the child; 2) a supportive school matters; and, 3) the programme needs to feel personal. Parents were more likely to have a positive experience at a parenting programme, and for their child to demonstrate positive behavioural changes, when they felt their concerns were validated within the group and they also felt supported by the child's teachers. Parents whose children had been assessed prior to undertaking the programme were also more likely to perceive the programme to be beneficial, compared to parents who felt their child's individual issues were never considered. CONCLUSIONS: Our findings point to the potential for personalised approaches to extend the reach of parenting programmes to parents and children who do not currently benefit from such programmes. Important in personalising parenting programmes is assessing children before parents are referred, to directly work with children as well as parents, and to work collaboratively with parents and children to identify which families are most suited to group support or one-to-one support and how this may change depending on circumstances.

RESUMO

BACKGROUND: Recruiting patients to paediatric trials can be challenging, especially in trials that compare markedly different management pathways and are conducted in acute settings. We aimed to enhance informed consent and recruitment in the CONTRACT trial (CONservative TReatment of Appendicitis in Children a randomised controlled Trial; ISRCTN15830435) - a feasibility trial that compared non-operative treatment (antibiotics) versus appendicectomy for uncomplicated acute appendicitis. METHODS: Qualitative study embedded within CONTRACT and conducted across three UK children's hospitals. Data were transcribed audio-recordings of 85 CONTRACT recruitment consultations with 58 families; and semi-structured interviews with 35 health professionals and 28 families (34 parents, 14 children) invited to participate in CONTRACT. Data analysis drew on thematic approaches. Throughout CONTRACT, we used findings from the ongoing qualitative analysis to inform bespoke communication training for health professionals recruiting to CONTRACT. Before and after training we also examined qualitative changes in communication during consultations and quantitative changes in recruitment rates. RESULTS: Bespoke communication training focussed on presenting the trial arms in a balanced way, emphasising clinical equipoise, exploring family treatment preferences and managing families' expectations about the trial's treatment pathways. Analysis of recruitment consultations indicated that health professionals' presentation of treatment arms became increasingly balanced following training, (e.g. avoiding imbalanced terminology) and recruitment rose from 38 to 62%. However, they remained reluctant to explore families' treatment preferences and respond with further information to balance these preferences. Analyses of interviews identified the time constraints of the urgent care setting, concerns about coercion, and reservations about exposing children to conversations about treatment risks as reasons for this reluctance. Interviews with families indicated the importance of clear explanations of trial treatment timings and sensitive communication of treatment allocation for both recruitment and retention. CONCLUSIONS: Following bespoke training based on the qualitative analyses, health professionals presented CONTRACT to families in clearer and more balanced ways and this was associated with an increase in the recruitment rate. Despite training, health professionals remained reluctant to explore families' treatment preferences. We provide several recommendations to enhance communication, informed consent, recruitment and retention in future trials in urgent care settings.

OBJECTIVE: To characterize the macronutrient, energy, and zinc composition of pasteurized donor human milk pools and evaluate how composition varies based on pooling practices and "time postpartum" (ie, elapsed time from parturition to expression date) of individual milk donations. STUDY DESIGN: The Mothers' Milk Bank (Arvada, Colorado) donated 128 donor human milk pools. Caloric density was assessed via mid-infrared spectroscopy, and zinc concentration was measured by atomic absorption spectroscopy. Pool time postpartum was calculated as the unweighted average of the time postpartum of all milk donations included in any given pool. RESULTS: Time postpartum of donor human milk pools ranged from 3 days to 9.8 months. The majority (91%) of donor human milk pools included milk from either 1 donor or 2 donors. Pool energy density ranged from 14.7 to 23.1 kcal/oz, and protein ranged from 0.52 to 1.43 g/dL. Milk zinc concentrations were higher in preterm pools and were negatively correlated with pool time postpartum. We present an equation that estimates donor human milk pool zinc content based on time postpartum and explains 49% of the variability in zinc concentrations (P < .0001). Including more donors in donor human milk pools decreased the variability in protein, but not zinc, concentrations. CONCLUSIONS: Donor human milk pools were lower in calories than is normally assumed in standard human milk fortification practices. Zinc concentrations were related to donor human milk time postpartum and were on average insufficient to meet preterm and term infants' needs without fortification or supplementation.

RESUMO

BACKGROUND: Innovative ways of planning and conducting research have emerged recently, based on the concept of collective intelligence. Collective intelligence is defined as shared intelligence emerging when people are mobilized within or outside an organization to work on a specific task that could result in more innovative outcomes than those when individuals work alone. Crowdsourcing is defined as "the act of taking a job traditionally performed by a designated agent and outsourcing it to an undefined, generally large group of people in the form of an open call." OBJECTIVE: This qualitative study aimed to identify the barriers to mobilizing collective intelligence and ways to overcome these barriers and provide good practice advice for planning and conducting collective intelligence projects across different research disciplines. METHODS: We conducted a multinational online open-ended question survey and semistructured audio-recorded interviews with a purposive sample of researchers who had experience in running collective intelligence projects. The questionnaires had an interactive component, enabling respondents to rate and comment on the advice of their fellow respondents. Data were analyzed thematically, drawing on the framework method. RESULTS: A total of 82 respondents from various research fields participated in the survey (n=65) or interview (n=17). The main barriers identified were the lack of evidence-based guidelines for implementing collective intelligence, complexity in recruiting and engaging the community, and difficulties in disseminating the results of collective intelligence projects. We drew on respondents' experience to provide tips and good practice advice for governance, planning, and conducting collective intelligence projects. Respondents particularly suggested establishing a diverse coordination team to plan and manage collective intelligence projects and setting up common rules of governance for participants in projects. In project planning, respondents provided advice on identifying research problems that could be answered by collective intelligence and identifying communities of participants. They shared tips on preparing the task and interface and organizing communication activities to recruit and engage participants. CONCLUSIONS: Mobilizing collective intelligence through crowdsourcing is an innovative method to increase research efficiency, although there are several barriers to its implementation. We present good practice advice from researchers with experience of collective intelligence across different disciplines to overcome barriers to mobilizing collective intelligence.

RESUMO

OBJECTIVE: To use a quantitative approach to evaluate the literature for quantity, quality, and consistency of studies of maternal and infant characteristics in association with breastfeeding initiation and continuation, and to conduct a meta-analysis to produce summary relative risks (RRs) for selected factors. STUDY DESIGN: A systematic review using PubMed and CINAHL through March 2016 was conducted to identify relevant observational studies in developed nations, reporting a measure of risk for 1 or more of 6 quantitatively derived, high impact factors in relation to either breastfeeding initiation or continuation. One author abstracted data using a predesigned database, which was reviewed by a second independent author; data evaluation and interpretation included all co-authors. These factors were summarized using standard meta-analysis techniques. RESULTS: Six high impact factors were identified (smoking [39 papers], mode of delivery [47 papers], parity [31 papers], dyad separation [17 papers], maternal education [62 papers], and maternal breastfeeding education [32 papers]). Summary RR from random-effects models for breastfeeding initiation were highest for high vs low maternal education (RR 2.28 [95% CI 1.92-2.70]), dyad connection vs not (RR 2.01 [95% CI 1.38-2.92]), and maternal nonsmoking vs smoking (RR = 1.76 [95% CI 1.59-1.95]); results were similar for breastfeeding continuation. CONCLUSIONS: Despite methodological heterogeneity across studies, relatively consistent results were observed for these perinatally identifiable factors associated with breastfeeding initiation and continuation, which may be informative in developing targeted interventions to provide education and support for successful breastfeeding in more families.

RESUMO

OBJECTIVES: Practitioners treating patients with haematological cancers have extensive clinical information available to give to patients, and patients need to be informed. However, many patients want to be protected from having information that is too detailed or threatening. To illuminate how practitioners can address this dilemma and help patients feel appropriately informed, we explored patients' experience of feeling informed or uninformed. METHODS: Semi-structured interviews were conducted with 20 patients who had been diagnosed with haematological cancer and had recently received results from clinical investigations or from evaluations of treatment response. Inductive and interpretive analysis of the transcribed audio-recorded interviews drew on constant comparison. RESULTS: Patients described the need for practitioners carefully to manage the information that they provided, and many felt alarmed by information that they did not experience as having been managed for them. A few patients who had difficulty trusting practitioners were not content with the information provided. CONCLUSIONS: These findings can be understood using attachment theory, whereby practitioners' careful management of information demonstrates their care for patients, and patients' trust in the practitioner enables them to feel informed. It follows that, when patients do not feel informed, the solution will not necessarily be more information but might be to help patients feel more secure in a caring clinical relationship.

RESUMO

Anxiety disorders are among the most common mental health disorders experienced by children, but only a minority of these children access professional help. Understanding the difficulties parents face seeking support for child anxiety disorders could inform targeted interventions to improve treatment access. The aims of the study were to identify barriers and facilitators to seeking and accessing professional support for child anxiety disorders, and ways to minimise these barriers. A qualitative interview study was conducted with parents of 16 children (aged 7-11 years) with anxiety disorders identified through screening in schools. Barriers and facilitators were identified in relation to four distinct stages in the help-seeking process: parents recognising the anxiety difficulty, parents recognising the need for professional support, parents contacting professionals, and families receiving professional support. Barriers and facilitators at each stage related to the child's difficulties, the role of the parent, and parent perceptions of professionals and services. Findings illustrate the need (1) for readily available tools to help parents and professionals identify clinically significant anxiety in children, (2) to ensure that families and professionals can easily access guidance on the help-seeking process and available support, and (3) to ensure existing services offer sufficient provision for less severe difficulties that incorporates direct support for parents.
