Development and validation of age-specific predictive equations for total energy expenditure and physical activity levels for older adults

BACKGROUND

Predicting energy requirements for older adults is compromised by the underpinning data being extrapolated from younger adults.

OBJECTIVES

To generate and validate new total energy expenditure (TEE) predictive equations specifically for older adults using readily available measures (age, weight, height) and to generate and test new physical activity level (PAL) values derived from 1) reference method of indirect calorimetry and 2) predictive equations in adults aged ≥65 y.

METHODS

TEE derived from "gold standard" methods from n = 1657 (n = 1019 females, age range 65-90 y), was used to generate PAL values. PAL ranged 1.28-2.05 for males and 1.26-2.06 for females. Physical activity (PA) coefficients were also estimated and categorized (inactive to very active) from population means. Nonlinear regression was used to develop prediction equations for estimating TEE. Double cross-validation in a randomized, sex-stratified, age-matched 50:50 split, and leave one out cross-validation were performed. Comparisons were made with existing equations.

RESULTS

Equations predicting TEE using the Institute of Medicine method are as follows: For males, TEE = -5680.17 - 17.50 × age (years) + PA coefficient × (6.96 × weight [kilograms] + 44.21 × height [centimeters]) + 1.13 × resting metabolic rate (RMR) (kilojoule/day). For females, TEE = -5290.72 - 8.38 × age (years) + PA coefficient × (9.77 × weight [kilograms] + 41.51 × height [centimeters]) + 1.05 × RMR (kilojoule/day), where PA coefficient values range from 1 (inactive) to 1.51 (highly active) in males and 1 to 1.44 in females respectively. Predictive performance for TEE from anthropometric variables and population mean PA was moderate with limits of agreement approximately ±30%. This improved to ±20% if PA was adjusted for activity category (inactive, low active, active, and very active). Where RMR was included as a predictor variable, the performance improved further to ±10% with a median absolute prediction error of approximately 4%.

CONCLUSIONS

These new TEE prediction equations require only simple anthropometric data and are accurate and reproducible at a group level while performing better than existing equations. Substantial individual variability in PAL in older adults is the major source of variation when applied at an individual level.

The graduate dietitian experience of employment and employability: A longitudinal qualitative research study from one Australian university

AIMS

Diet-related chronic disease contributes significantly to the global burden of disease. Dietitians are best placed to address this disease burden, yet graduate dietitians may struggle to find employment. This study aimed to explore dietetics graduates' experiences of employment and employability, up to 6-month post-degree completion.

METHODS

Secondary data analysis of in-depth qualitative interview data and longitudinal audio-diaries was undertaken. An interpretivist approach was employed whereby knowledge was viewed as subjective and multiple realities exist. A total of five entrance interviews, 31 audio-diaries and three exit interviews, from nine graduates were included in the analysis. This comprised 12 h of longitudinal audio data. Thematic analysis was undertaken using a framework analysis method.

RESULTS

Four key themes were identified: (1) The tumultuous process of applying for jobs demonstrated that graduates struggled with repeated rejections. (2) The uncertain journey to employment indicated that job-seeking was a limbo stage marked by uncertainty. (3) Feeling the pressure showed that graduates experienced pressure from multiple sources. (4) Enhancing employability explained that graduates were not prepared for available employment opportunities, but utilised resources to increase their employability.

CONCLUSION

Diverse placement experiences may better prepare graduates for available employment opportunities. To enhance employability, it may be beneficial to assist students to develop job-seeking skills, and to engage in networking and volunteering experiences during their education.

Investigating the efficacy and feasibility of using a whole-of-diet approach to lower circulating levels of C-reactive protein in postmenopausal women: a mixed methods pilot study

OBJECTIVE

Chronic inflammation is associated with obesity and is an underlying pathophysiology for cardiovascular disease (CVD) development in postmenopausal women. This study aims to determine feasibility and efficacy of an anti-inflammatory dietary intervention to lower levels of C-reactive protein in weight stable postmenopausal women with abdominal obesity.

METHODS

This mixed-methods pilot study used a single arm pre-post design. Thirteen women followed a 4-week anti-inflammatory, dietary intervention, optimizing consumption of healthy fats, low glycemic index wholegrains, and dietary antioxidants. Quantitative outcomes included change in inflammatory and metabolic markers. Focus groups were undertaken and thematically analyzed to explore participants lived experience of following the diet.

RESULTS

There was no significant change in plasma high-sensitivity C-reactive, protein. Despite discouraging weight loss, median (Q1-Q3) body weight decreased by -0.7 (-1.3 to 0 kg, P = 0.02). This was accompanied by reductions in plasma insulin (0.90 [-0.05 to 2.20] mmol/L), Homeostatic Model Assessment of Insulin Resistance (0.29 [-0.03 to 0.59]), and low-density lipoprotein:high-density lipoprotein ratio (0.18 [-0.01 to 0.40]) ( P ≤ 0.023 for all). Thematic analysis revealed that postmenopausal women have a desire to improve meaningful markers of health status that do not focus on weight. Women were highly engaged with learning about emerging and innovative nutrition topics, favoring a detailed and comprehensive nutrition education style that challenged their proficient health literacy and cooking skills.

CONCLUSIONS

Weight-neutral dietary interventions targeting inflammation can improve metabolic markers and may be a viable strategy for CVD risk reduction in postmenopausal women. To determine effects on inflammatory status, a fully powered and longer-term randomized controlled trial is required.

Evaluating a 10-Week Family-Focused E-Health Healthy Lifestyle Program for School-Aged Children with Overweight or Obesity: A Randomized Controlled Trial Study Protocol

E-Health childhood obesity treatment interventions may serve as favorable alternatives to conventional face-to-face programs. More studies are needed to evaluate the effectiveness of such interventions beyond immediately post-program completion, including exploring program features impacting effectiveness. This randomized controlled trial with a qualitative component and waitlisted control group will evaluate the effectiveness of a 10-week family-focused e-Health program for school-aged children with overweight/obesity and explore the experience of families completing the program. The primary outcome is the change in BMI z-score and will be assessed from baseline to 10 weeks. Secondary outcomes include (the change in) waist circumference, dietary intake, physical activity, quality of life, and experiences, and will be assessed at baseline, post-10 weeks, and/or immediately, 3-, 6-, and/or 12-months post-program completion. Independent t-tests will be used to compare the differences in means and analyses of variances (ANOVAs) will be conducted to investigate the impact of the program or of being waitlisted and the effect size of the program on quantitative outcome measures. Reflexive thematic analysis will be used with qualitative data. Findings from this study are expected to provide learnings to upscale conventional childhood obesity treatment services, in the hopes of curbing the rising rate of childhood obesity.

Development and validation of new predictive equations for the resting metabolic rate of older adults aged ≥65 y

BACKGROUND

The aging process alters the resting metabolic rate (RMR), but it still accounts for 50%-70% of the total energy needs. The rising proportion of older adults, especially those over 80 y of age, underpins the need for a simple, rapid method to estimate the energy needs of older adults.

OBJECTIVES

This research aimed to generate and validate new RMR equations specifically for older adults and to report their performance and accuracy.

METHODS

Data were sourced to form an international dataset of adults aged ≥65 y (n = 1686, 38.5% male) where RMR was measured using the reference method of indirect calorimetry. Multiple regression was used to predict RMR from age (y), sex, weight (kg), and height (cm). Double cross-validation in a randomized, sex-stratified, age-matched 50:50 split and leave one out cross-validation were performed. The newly generated prediction equations were compared with the existing commonly used equations.

RESULTS

The new prediction equation for males and females aged ≥65 y had an overall improved performance, albeit marginally, when compared with the existing equations. It is described as follows: RMR (kJ/d) = 31.524 × W (kg) + 25.851 × H (cm) - 24.432 × Age (y) + 486.268 × Sex (M = 1, F = 0) + 530.557. Equations stratified by age (65-79.9 y and >80 y) and sex are also provided. The newly created equation estimates RMR within a population mean prediction bias of ∼50 kJ/d (∼1%) for those aged ≥65 y. Accuracy was reduced in adults aged ≥80 y (∼100 kJ/d, ∼2%) but was still within the clinically acceptable range for both males and females. Limits of agreement indicated a poorer performance at an individual level with 1.96-SD limits of approximately ±25%.

CONCLUSIONS

The new equations, using simple measures of weight, height, and age, improved the accuracy in the prediction of RMR in populations in clinical practice. However, no equation performs optimally at the individual level.

Exploring Overnutrition, Overweight, and Obesity in the Hospital Setting-A Point Prevalence Study

Malnutrition is an international healthcare concern associated with poor patient outcomes, increased length of stay, and healthcare costs. Although malnutrition includes both under and overnutrition, there is a large body of evidence that describes the impacts of undernutrition with limited data on overnutrition in hospitalized patients. Obesity itself is a modifiable risk factor associated with hospital-associated complications. However, there is limited reporting of the prevalence of obesity in hospitals. This one-day cross-sectional study (n = 513) captures the prevalence of both under and overnutrition in a hospitalized population and explores dietetic care provided compared to the Nutrition Care Process Model for hospitalized patients who have obesity. The main findings were: (1) the largest proportion of patients were in the overweight and obese classifications (57.3%, n = 294/513); 5.3% of these patients had severe obesity (class III); (2) patients who were overweight and obese had lower malnutrition risk profiles as well as the prevalence of malnutrition; (3) 24.1% of patients who had obesity (n = 34/141) were receiving dietetic intervention; (4) 70.6% (n = 24/34) did not have a nutrition diagnosis that followed the Nutrition Care Process Model. Study results provide valuable clinical insight into the prevalence of overnutrition and opportunities to improve nutrition care for this vulnerable patient group.

Exploring stakeholder experiences of dietetic service and care delivery: A systematic qualitative review

BACKGROUND

There is limited understanding of patients' and healthcare professionals' perceptions and experiences of receiving and delivering dietetic care, respectively. This systematic review of the literature used qualitative synthesis to explore the perceptions and experiences of multiple stakeholders involved in the delivery of nutrition care and dietetic service.

METHODS

MEDLINE, Embase, CINAHL, Cochrane Library, Scopus, ISI Web of Science, PsycINFO and ProQuest were systematically searched. Study characteristics and perceptions of stakeholders regarding nutrition care services were extracted. Qualitative synthesis was employed and thematic analysis conducted.

RESULTS

Five themes were identified from 44 studies related to stakeholders' perceptions of dietetic services. Studies included quantitative, qualitative and mixed methods involving patients, families, dietitians and other healthcare professionals. The themes were (1) patients desiring a personalised approach to nutrition care; (2) accessing dietetic service; (3) perceived impact of nutrition care on the patient; (4) relationships between stakeholders; and (5) beliefs about nutrition expertise. Two themes were specific to patients; these were the desire for individualised care and the impact of nutrition care. Within each theme perceptions varied with patients' views often contrasting with those of dietetic service providers.

CONCLUSIONS

Experiences of dietetic service do not always meet stakeholder expectations which impacts on patient engagement. Seeking stakeholder input is imperative to design dietetic services that engage patients in positive and supportive clinical partnerships.

Teacher, Gatekeeper, or Team Member: supervisor positioning in programmatic assessment

Competency-based assessment is undergoing an evolution with the popularisation of programmatic assessment. Fundamental to programmatic assessment are the attributes and buy-in of the people participating in the system. Our previous research revealed unspoken, yet influential, cultural and relationship dynamics that interact with programmatic assessment to influence success. Pulling at this thread, we conducted secondary analysis of focus groups and interviews (n = 44 supervisors) using the critical lens of Positioning Theory to explore how workplace supervisors experienced and perceived their positioning within programmatic assessment. We found that supervisors positioned themselves in two of three ways. First, supervisors universally positioned themselves as a Teacher, describing an inherent duty to educate students. Enactment of this position was dichotomous, with some supervisors ascribing a passive and disempowered position onto students while others empowered students by cultivating an egalitarian teaching relationship. Second, two mutually exclusive positions were described-either Gatekeeper or Team Member. Supervisors positioning themselves as Gatekeepers had a duty to protect the community and were vigilant to the detection of inadequate student performance. Programmatic assessment challenged this positioning by reorientating supervisor rights and duties which diminished their perceived authority and led to frustration and resistance. In contrast, Team Members enacted a right to make a valuable contribution to programmatic assessment and felt liberated from the burden of assessment, enabling them to assent power shifts towards students and the university. Identifying supervisor positions revealed how programmatic assessment challenged traditional structures and ideologies, impeding success, and provides insights into supporting supervisors in programmatic assessment.

The Australian and New Zealand dietetics graduate outcomes survey: A cross-sectional study

AIM

There is a paucity of comprehensive and current employment data for dietitians. It is unclear if, and where, dietetics graduates are being employed and if they are sufficiently prepared to meet workforce and community needs. The aim of this study was to identify employment outcomes for recent dietetics graduates from Australia and New Zealand at 4-6 months post degree completion.

METHODS

A cross-sectional survey was distributed to graduates from accredited dietetics degrees across Australian and New Zealand. Those who completed their university study in 2020 were eligible to participate. Descriptive statistics and frequencies were analysed and open text answers underwent summative content analysis.

RESULTS

A total of 294 usable survey responses were received from 631 eligible graduates (response rate 47%). Seventy-five percent of graduates were employed in any field and 60% were employed in a role that required their degree. The most common area of dietetics employment was private practice, followed by hospital practice. Most commonly, graduates who did not need their degree to get their job were employed in healthcare-related roles, or nutrition- and food-related roles.

CONCLUSIONS

These findings are important for curricula development to ensure that students are suitably prepared for available employment opportunities. Work-integrated learning experiences may need to shift focus to skill development, rather than a specific job role, to better prepare graduates for the jobs of the future. Further monitoring of employment outcomes is necessary to track changes over time.

Meals That Differ in Nutrient Composition and Inflammatory Potential Do Not Differentially Impact Postprandial Circulating Cytokines in Older Adults above a Healthy Weight

In this exploratory study, mixed meals specifically formulated to differ in inflammatory potential were tested to determine whether they could differentially impact circulating levels of inflammatory markers in adults above a healthy weight. Complete data were analyzed from 11 adults (6 males and 5 females) aged 54−63 years with median BMI of 30.0 (27.1−31.6) kg/m². In a crossover study design, each participant consumed an isocaloric (2.2 MJ) meal with either a low (Anti-meal), moderate (Neutr-meal), or high (Pro-meal) inflammatory potential. Fasting and postprandial blood samples were analyzed for plasma levels of IL-6, IL-1β, TNF-α, IL-10, and metabolic makers. Postprandial plasma IL-6, IL-1β, TNF-α, and IL-10 incremental areas under the curve (iAUC) were not different between the three meals (p > 0.05). There was a trend of an increase in IL-6 with time in all three meals, but no changes were obvious for the other measured cytokines. The Pro-meal induced an increased postprandial iAUC for triglycerides compared to the Anti-meal and Neutr-meal (p = 0.004 and p = 0.012, respectively). Single meals, regardless of their theoretical inflammatory potential, did not substantially shift circulating inflammatory markers, suggesting that longer-term dietary patterns are important rather than single dietary exposures in the pathology of metabolic conditions.

Tackling the challenge of treating obesity using design research methods: A scoping review

Design research methods, including user-centered design, human-centered design, and design thinking, are iterative processes and frameworks that engage stakeholders to inform the design of initiatives, programs, or research interventions. Design research methods are not yet widely applied in healthcare. To date, there is a limited understanding of how design research methodologies can be applied to develop client-centered weight loss interventions. This scoping review explores the extent, range, and nature of research projects that used design research methods to guide the development of an obesity treatment intervention. A systematic search of eight databases identified projects that used design research methods to develop a weight loss intervention or strategy. The method and practical application of design research processes for each eligible article were extracted and explored. Design research methods were used to generate ideas or guide the development of a mobile application (n = 6), mHealth device (n = 1), eHealth solution (n = 1), health promotion program (n = 1), or patient-clinician communication tools (n = 2). There was considerable variation in the application of design research processes between studies. Design research methods may provide an iterative, flexible framework to facilitate the development of client-centered, inclusive interventions and strategies. Design research methods may support research teams to move away from the one-size-fits-all approach to obesity treatment.

Outcome of caudal superficial epigastric axial pattern flaps in dogs and cats: 70 cases (2007-2020)

OBJECTIVES

To describe the outcome and complications associated with the use of caudal superficial epigastric axial pattern flaps in dogs and cats.

MATERIAL AND METHODS

Multicentre retrospective review and descriptive study of clinical records of dogs and cats having undergone caudal superficial epigastric axial pattern flaps between 2007 and 2020. Data retrieved included signalment, aetiology of surgical defect, tumour type, presence/absence of clean surgical margins, presence/absence of post-operative wound infection, use of peri- and post-operative antibiotics, duration of anaesthesia, duration of surgery, presence and duration of hypothermia, presence and duration of hypotension, presence/absence of post-operative surgical drain and length of caudal superficial epigastric axial pattern flap. The incidence of complications and outcomes were documented.

RESULTS

Seventy cases met the inclusion criteria; 51 dogs and 19 cats. In dogs, 67% of cases developed complications (59% minor, 8% major) and 33% had uneventful wound healing. In cats, 53% of cases developed complications, (47% minor, 5% major) and 47% had uneventful wound healing. In dogs, the percentage of cases experiencing dehiscence, necrosis, seroma, oedema and post-operative infection was 31%, 29%, 26%, 26% and 16% respectively. In cats, this was 26%, 16%, 11%, 0% and 5% respectively. A good overall outcome was seen in 77% of dogs and 79% of cats. A poor overall outcome was seen in 4% of dogs and 0% of cats.

CLINICAL SIGNIFICANCE

Caudal superficial epigastric axial pattern flaps are traditionally thought more robust than other flaps, yet complication rates remain high, despite a high overall success rate.

Trends, challenges, opportunities, and future needs of the dietetic workforce: a systematic scoping review

CONTEXT

Issues related to nutrition and health are prominent, yet it is unclear if the dietetics workforce is being used optimally.

OBJECTIVE

Trends, challenges, opportunities, and future needs of the international dietetic workforce are investigated in this review, which was registered with Open Science Framework (10.17605/OSF.IO/DXNWE).

DATA SOURCES

Eight academic and 5 grey-literature databases and the Google search engine were searched from 2010 onward according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Of 2050 articles screened, 184 were eligible for inclusion.

DATA EXTRACTION

To chart data, a directed content analysis and a constant comparison technique were used.

DATA ANALYSIS

The following 13 themes were identified: 1) emerging or expanding areas of practice; 2) skill development; 3) economic considerations; 4) nutrition informatics; 5) diversity within the workforce; 6) specific areas of practice; 7) further education; 8) intrapersonal factors; 9) perceptions of the profession; 10) protecting the scope of practice; 11) support systems; 12) employment outcomes; and 13) registration or credentialing.

CONCLUSIONS

The dietetics profession is aware of the need to expand into diverse areas of employment. Comprehensive workforce data are necessary to facilitate workforce planning.

Implementing programmatic assessment transforms supervisor attitudes: An explanatory sequential mixed methods study

INTRODUCTION

Programmatic assessment (PA) is an increasingly popular approach to competency-based assessment (CBA), yet evaluation evidence is limited. This study aimed to identify and explore supervisor attitudes before and after implementing a novel PA using a sequential explanatory mixed methods design. In phase one, a survey was used to identify supervisor perspectives on work-based placements, PA and CBA. Survey results were then applied to develop focus group questions to further explore supervisor attitudes.

RESULTS

PA was found to improve supervisor-student relationships by removing high-stakes assessment decisions and creating greater capacity for feedback and teaching, leading to a productive learning environment. Assessment was perceived as an important role and supervisors wanted to feel valued and heard within PA. Trust was conceptualised as a triad between supervisor, student and university, and enabled supervisors to engage with PA which was important for success. Supervisor learning of PA was experiential and often supported by students, highlighting the need for hands-on training.

CONCLUSION

Participants reported a high level of agreement with PA and CBA principles which may have made them amenable to educational change. Further research is needed to explore the experience of all stakeholders and to understand how worldviews and culture influence assessment initiatives.

Understanding children and young people's experiences pursuing weight loss maintenance using the Socio-ecological Model: A qualitative systematic literature review

Developing a broader understanding of children and young people's experiences of long-term attempts of weight management may provide insight into both enablers and barriers to successful weight loss maintenance. This review aims to explore children and young people's perceptions of long-term attempts of weight management. Six databases were searched for qualitative studies describing young participants (<25 years, previously or currently above a healthy weight) experiences of weight management for >6 months following intentional weight loss. A thematic synthesis was undertaken. Themes were interpreted using the Socio-ecological Model. Factors supporting attempts to maintain weight loss included having clear motivation for change; developing personal skills to manage the challenges of change; family support/dynamics that encourage healthy lifestyles; and health-promoting cultures in schools/workplaces, communities, and the broader living environment. Conversely, ambivalence, difficulty coping with changes, peer pressure, challenging family dynamics, limited professional support, and unhealthy living environments were barriers to maintaining behavior change. These facilitators and barriers at each level of the Socio-ecological Model informed a model of weight loss maintenance for children and young people. Supporting children, young people, and families to develop the skills to manage the individual, social, and environmental challenges that shape attempts of long-term weight management will help to support their ability to manage their weight long term.

Machine learning approach to muon spectroscopy analysis

In recent years, artificial intelligence techniques have proved to be very successful when applied to problems in physical sciences. Here we apply an unsupervised machine learning (ML) algorithm called principal component analysis (PCA) as a tool to analyse the data from muon spectroscopy experiments. Specifically, we apply the ML technique to detect phase transitions in various materials. The measured quantity in muon spectroscopy is an asymmetry function, which may hold information about the distribution of the intrinsic magnetic field in combination with the dynamics of the sample. Sharp changes of shape of asymmetry functions-measured at different temperatures-might indicate a phase transition. Existing methods of processing the muon spectroscopy data are based on regression analysis, but choosing the right fitting function requires knowledge about the underlying physics of the probed material. Conversely, PCA focuses on small differences in the asymmetry curves and works without any prior assumptions about the studied samples. We discovered that the PCA method works well in detecting phase transitions in muon spectroscopy experiments and can serve as an alternative to current analysis, especially if the physics of the studied material are not entirely known. Additionally, we found out that our ML technique seems to work best with large numbers of measurements, regardless of whether the algorithm takes data only for a single material or whether the analysis is performed simultaneously for many materials with different physical properties.

The Value of Programmatic Assessment in Supporting Educators and Students to Succeed: A Qualitative Evaluation

BACKGROUND

Programmatic assessment has been proposed as the way forward for competency-based assessment, yet there is a dearth of literature describing the implementation and evaluation of programmatic assessment approaches.

OBJECTIVE

To evaluate the implementation of a programmatic assessment and explore its ability to support students and assessors.

DESIGN

A qualitative evaluation of programmatic assessment was employed.

PARTICIPANTS/SETTING

Interviews with graduates (n = 8) and preceptors (n = 12) together with focus groups with faculty assessors (n = 9) from the one Australian university explored experiences of the programmatic approach, role of assessment in learning, and defensibility of assessment decisions in determining competence.

ANALYSIS PERFORMED

Data were analyzed into key themes using framework analysis.

RESULTS

The programmatic assessment increased confidence in defensibility of assessment decisions, reduced emotional burden of assessment, increased value of assessment, and identified and remediated at-risk students earlier when philosophical and practice shifts in approaches to assessment were embraced.

CONCLUSIONS

Programmatic assessment supports a holistic approach to competency development and assessment and has multiple benefits for learners and assessors.

Impact of intra-operative hypotension on mortality rates and post-operative complications in dogs undergoing cholecystectomy

OBJECTIVES

To report the mortality rate within a cohort of dogs undergoing cholecystectomy and investigate the impact of intra-operative hypotension on mortality.

MATERIALS AND METHODS

Clinical records at five UK referral centres were reviewed for dogs undergoing cholecystectomy. Data collected included presenting signs, pre-operative blood test results, intra-operative data including frequency and duration of hypotension and the incidence and type of post-operative complications.

RESULTS

Data from 119 dogs were included. Sixteen dogs (13%) died before discharge and by 28 days after surgery the total mortality was 19 dogs (17%). Hypotension lasting over 10 minutes during general anaesthesia occurred in 65 dogs (54.6%), with a mean ± sd duration of 36.1 ± 30.0 minutes. Intra-operative hypotension or the number of hypotensive episodes did not appear to be associated with in-hospital or 28-day mortality. American Society of Anaesthesiologists grade (of fitness for surgery) was significantly associated with both in-hospital and 28-day mortality on univariable analysis, as were post-operative hypoproteinaemia, ileus and pancreatitis. However on multivariable analysis, only ileus and pancreatitis were found to significantly impact mortality.

CLINICAL SIGNIFICANCE

Dogs presenting with a higher American Society of Anaesthesiologists grade appear to have a higher risk of mortality, although intra-operative hypotension did not appear to be part of this risk.

Using the Internet: Nutrition Information-Seeking Behaviours of Lay People Enrolled in a Massive Online Nutrition Course

People's accessibility to nutrition information is now near universal due to internet access, and the information available varies in its scientific integrity and provider expertise. Understanding the information-seeking behaviours of the public is paramount for providing sound nutrition advice. This research aims to identify who learners in a nutrition-focused Massive Open Online Course (MOOC) turn to for nutrition information, and how they discuss the information they find. A multi-methods approach explored the information-seeking and sharing behaviours of MOOC learners. Summative content analysis, and an exploratory, inductive, qualitative approach analysed learners' posts in MOOC discussion forums. From 476 posts, the majority (58.6%) of nutrition information sources learners reported were from websites. Providers of nutrition information were most commonly (34%) tertiary educated individuals lacking identifiable nutrition qualifications; 19% had no identifiable author information, and only 5% were from nutrition professionals. Qualitative themes identified that learners used nutrition information to learn, teach and share nutrition information. Consistent with connectivist learning theory, learners contributed their own sources of nutrition information to discussions, using their own knowledge networks to teach and share information. Nutrition professionals need to understand the principles of connectivist learning behaviours in order to effectively engage the public.

Social media, body image and food choices in healthy young adults: A mixed methods systematic review

AIM

Negative body image increases the risk of engaging in unhealthy dieting and disordered eating patterns. This review evaluated the impact of habitual social media engagement or exposure to image-related content on body image and food choices in healthy young adults (18-30 years).

METHODS

A systematic search of six databases of observational literature published 2005-2019, was conducted (PROSPERO Registration No. CRD42016036588). Inclusion criteria were: studies reporting social media engagement (posting, liking, commenting) or exposure to image-related content in healthy young adults. Outcomes were: body image (satisfaction or dissatisfaction) and food choices (healthy eating, dieting/restricting, overeating/binging). Two authors independently screened, coded and evaluated studies for methodological quality.

RESULTS

Thirty studies were identified (n = 11 125 participants). Quantitative analysis (n = 26) identified social media engagement or exposure to image-related content was associated with higher body dissatisfaction, dieting/restricting food, overeating, and choosing healthy foods. Qualitative analysis (n = 4) identified five themes: (i) social media encourages comparison between users, (ii) comparisons heighten feelings about the body, (iii) young adults modify their appearance to portray a perceived ideal image, (iv) young adults are aware of social media's impact on body image and food choices, however, (v) external validation via social media is pursued. Most studies (n = 17) controlled for some confounding variables (age, gender, BMI, ethnicity).

CONCLUSIONS

Social media engagement or exposure to image-related content may negatively impact body image and food choice in some healthy young adults. Health professionals designing social media campaigns for young adults should consider image-related content, to not heighten body dissatisfaction.

Promoting Evidence Based Nutrition Education Across the World in a Competitive Space: Delivering a Massive Open Online Course

The internet is the fastest growing source of nutrition information for consumers. Massive Open Online Courses (MOOCs) provide and avenue for nutrition professionals’ urgent need to respond to consumer demand for low-cost, accessible and engaging information. This research aimed to evaluate learner participation and perceptions in an evidence-based nutrition MOOC and provide recommendations for engaging international online lay audiences. Learners completed pre and post course surveys including quantitative and open-ended questions. Pre-course surveys collected demographic data, prior nutrition knowledge and motivations for doing the course. Post-course surveys evaluated their preferred learning modes and learners’ opinions of the course. Quantitative were analyzed using descriptive statistics. Conventional content analysis was conducted on learners’ responses to open-ended survey questions using an inductive approach. Learners represented 158 countries from a range of educational backgrounds. There were 3799 qualitative comments related to learners’ learning and course content preferences. Qualitative analysis identified key themes related to (1) online interaction, the (2) value of the evidence presented by nutrition experts and (3) the course structure and practical aspects. Divergent opinions were expressed within these themes. Satisfying the needs of large international audiences with diverse backgrounds is challenging in promoting sound evidence-based nutrition messages. MOOCs provide a means for delivering evidence based global nutrition education in the online space crowded with food advertising and nutrition conjecture. Recommendations are made as to how to construct and engage diverse on-line audiences.

Inflaming Public Interest: A Qualitative Study of Adult Learners' Perceptions on Nutrition and Inflammation

Research suggests national dietary guidelines are losing public resonance, with consumers actively seeking alternate nutrition advice from unregulated online platforms that often propagate misinformation. Improved diet quality can beneficially affect inflammation, and with science relating to nutrition and inflammation also appealing to consumers, this emerging topic provides an opportunity to consider how novel engagement strategies can be used to increase public support of expert-generated advice. This study aimed to qualitatively explore MOOC learners' perceptions and experiences of following diets believed to help manage inflammation. Data were collected from an evidence-based nutrition-focused Massive Open Online Course (MOOC), which included a unit titled Foods and Inflammation. The Framework method was used to analyze 12,622 learner comments, taken from the MOOC's online discussion forum and questionnaire. Learners identified avoidance of core food groups, such as dairy and grains, as key in managing inflammation. Dietary advice came mainly from the internet, and health professionals reportedly lacked an appreciation of the learners' underlying nutrition knowledge, providing oversimplified advice that did not satisfy their scientific curiosity. To help build consumer trust and increase engagement, health professionals need to consider innovative education strategies that utilize novel topics such as nutrition and inflammation, in a safe and accurate manner.

Total energy expenditure measured using doubly labeled water compared with estimated energy requirements in older adults (≥65 y): analysis of primary data

BACKGROUND

Contemporary energy expenditure data are crucial to inform and guide nutrition policy in older adults to optimize nutrition and health.

OBJECTIVE

The aim was to determine the optimal method of estimating total energy expenditure (TEE) in adults (aged ≥65 y) through 1) establishing which published predictive equations have the closest agreement between measured resting metabolic rate (RMR) and predicted RMR and 2) utilizing the RMR equations with the best agreement to predict TEE against the reference method of doubly labeled water (DLW).

METHODS

A database consisting of international participant-level TEE data from DLW studies was developed to enable comparison with energy requirements estimated by 17 commonly used predictive equations. This database included 31 studies comprising 988 participant-level RMR data and 1488 participant-level TEE data. Mean physical activity level (PAL) was determined for men (PAL = 1.69, n = 320) and women (PAL = 1.66, n = 668). Bland-Altman plots assessed agreement of measured RMR and TEE with predicted RMR and TEE in adults aged ≥65 y, and subgroups of 65-79 y and ≥80 y. Linear regression assessed proportional bias.

RESULTS

The Ikeda, Livingston, and Mifflin equations most closely agreed with measured RMR and TEE in all adults aged ≥65 y and in the 65-79 y and ≥80 y subgroups. In adults aged ≥65 y, the Ikeda and Livingston equations overestimated TEE by a mean ± SD of 175 ± 1362 kJ/d and 86 ± 1344 kJ/d, respectively. The Mifflin equation underestimated TEE by a mean ± SD of 24 ± 1401 kJ/d. Proportional bias was present as energy expenditure increased.

CONCLUSIONS

The Ikeda, Livingston, or Mifflin equations are recommended for estimating energy requirements of older adults. Future research should focus on developing predictive equations to meet the requirements of the older population with consideration given to body composition and functional measures.

Patient Involvement in Education of Nutrition and Dietetics Students: A Systematic Review

A client-centred approach sits at the core of modern healthcare. Exploration of the patients’ role within the education of nutrition and dietetic students has not previously been undertaken. This review aimed to synthesise the learning outcomes that result from involvement of patients in nutrition and dietetic student education, and to consider whether these interactions promote patient-centred care. Five electronic databases were searched, supported by hand-searching of references of included studies. Screening of title/abstract and then full text papers was undertaken; key characteristics and outcomes were extracted and synthesised narratively. The likely impact of interventions was evaluated using Kirkpatrick’s Hierarchy; study quality was assessed using the Medical Education Research Study Quality Instrument and Critical Appraisal Skills Programme checklist. Of 7436 studies identified through database searching, and one additional study located through hand searching of reference lists, the final library consisted of 13 studies. All studies reported benefits for student learning from patient involvement, while one paper identified patient benefits from student interventions. Patients as recipients of care mostly contributed in a passive role in student education activities. Quality assessment identified methodological limitations in most studies. Patient involvement in the education of dietitians supports skill development and therefore progression to professional practice. Although nutrition and dietetics education has a focus on client-centred care, the translation of these concepts into an interactive student educational experience has been investigated to a limited extent. Collaboration with patients in student education is an area for further development.

An unusual case of a completely eroded gastric band and port tubing removed via endoscopy alone

Bariatric surgery is an established intervention providing significant health benefits to patients with obesity. As a result, the National Institute for Health and Care Excellence now recommends bariatric surgery for those that fulfil the eligibility criteria, while emphasising the need for multidisciplinary care before and after surgery. The UK National Bariatric Surgery Registry shows gastric band procedures to be the second most common bariatric procedure performed in the UK. Gastric band erosion is a known potential complication treated primarily by laparoscopic removal of band and repair of stomach. To our knowledge, we present the first case of a partially eroded gastric band with separate gastric fistulation of the port tubing. The band was removed via endoscopy without the need for a cutaneous exploration as the port had previously been removed at incisional hernia surgery. Owing to the fact that the tubing and band were both evident within the lumen of the stomach, complete band erosion was inferred and therefore endoscopic removal thought to be indicated. In actual fact, there was separate erosion of the band and tubing; more specifically, the gastric band clasp had not eroded fully and while endoscopic removal was still possible, it was challenging and required the band to be divided. This case highlights the importance of careful patient selection, involvement of multidisciplinary care prior and after surgery and close follow-up to facilitate timely identification and management of complications.

Anaesthesia of brachycephalic dogs

Brachycephalic breeds of dog have grown in popularity in the UK and so form an increasing proportion of cases requiring anaesthesia. These breeds are predisposed to several conditions, notably brachycephalic obstructive airway syndrome and gastro-oesophageal reflux, that have important implications for anaesthetic management and carry high risk for complications. This review incorporates peer-reviewed veterinary literature with clinical experience in a discussion on perioperative management of brachycephalic dogs. We focus on preoperative identification of common concurrent conditions, practical strategies for reducing anaesthetic risk and improving postoperative management. Comparisons of brachycephalic obstructive airway syndrome with the human condition of obstructive sleep apnoea are included where appropriate.

Dental Public Health In Action: Putting Oral Health on the Local Public Health Agenda

Oral health is a key public health issue across England. In Wakefield in the north of England, local data suggested the oral health of local children was significantly worse than the national average. This paper describes the work undertaken by Wakefield Council to strategically address this issue. A structured process was adopted. Key lessons include; having senior ownership from the Director of Public Health, partnership working across all key stakeholders, utilising dental public health expertise from Public Health England and the use of extensive engagement with stakeholders. Through this work, oral health is now identified with greater importance in Wakefield as a public health issue. Actions are now strategically co-ordinated across stakeholders to improve oral health in local children.

The utility of patient reported data in a gynecologic oncology clinic

BACKGROUND

Measuring QoL is essential to the field of gynecologic oncology but there seems to be limited standardized data regarding collecting QoL assessments throughout a patient's cancer treatment especially in non-clinical trial patients. The aim of this study is to explore patient characteristics that may be associated with poor quality of life (QoL) in women with gynecologic cancers at two University of Arizona Cancer Center (UACC) sites.

METHODS

A cross-sectional survey was conducted among English speaking women with gynecologic malignancies at the University of Arizona Cancer Centers in Phoenix and Tucson from April 2012 to July 2015. The survey was a paper packet of questions that was distributed to cancer patients at the time of their clinic visit. The packet contained questions on demographic information, treatment, lifestyle characteristics, pelvic pain and Health-related quality of life (HRQoL). Measures included the generic and cancer-specific scores on the Functional Assessment of Cancer Therapy-General (FACT-G) and the Female Genitourinary Pain Index (GUPI). The total scores and subdomains were compared with descriptive variables (age, body mass index (BMI), diet, exercise, disease status, treatment and support group attendance) using Cronbach alpha (α), Spearman rank correlations (ρ), and Holm's Bonferroni method.

RESULTS

One-hundred and forty-nine women completed the survey; 55% (N = 81) were older than 60 years, 38% (N = 45) were obese (BMI > 30), 46% (N = 66) exercised daily, and 84% (N = 111) ate one or more daily serving of fruit and vegetables. Women in remission, those who exercised daily and ate fruits/vegetables were less likely to have their symptoms impact their QoL. Younger women were more likely to report genitourinary issues (p = - 0.22) and overall problems with QoL (p = - 0.29) than older women. Among FACT-G support group responses, we found those that did not attend support groups had a significantly higher emotional wellbeing (p = 0.05).

CONCLUSIONS

This study identified potential areas of clinical focus, which aid in understanding our approach to caring for gynecologic cancer patients and improvement of their HRQoL. We identified that age, pelvic pain, and lifestyle characteristics have indicators to poor QoL in women with gynecologic cancers. In this population, younger women and those with pelvic pain complaints, poor diet and exercise habits should be targeted early for supportive care interventions to improve QoL throughout both treatment and survivorship.

Total energy expenditure in adults aged 65 years and over measured using doubly-labelled water: international data availability and opportunities for data sharing

BACKGROUND

Increasing population lifespan necessitates a greater understanding of nutritional needs in older adults (65 year and over). A synthesis of total energy expenditure in the older population has not been undertaken and is needed to inform nutritional requirements. We aimed to establish the extent of the international evidence for total energy expenditure (TEE) using doubly-labelled water (DLW) in older adults (65 years and over), report challenges in obtaining primary data, and make recommendations for future data sharing.

METHODS

Four databases were searched to identify eligible studies; original research of any study design where participant level TEE was measured using DLW in participants aged ≥65 years. Once studies were identified for inclusion, authors were contacted where data were not publicly available.

RESULTS

Screening was undertaken of 1223 records; the review of 317 full text papers excluded 170 records. Corresponding or first authors of 147 eligible studies were contacted electronically. Participant level data were publicly available or provided by authors for 45 publications (890 participants aged ≥65 years, with 248 aged ≥80 years). Sixty-seven percent of the DLW data in this population were unavailable due to authors unable to be contacted or declining to participate, or data being irretrievable.

CONCLUSIONS

The lack of data access limits the value of the original research and its contribution to nutrition science. Openly accessible DLW data available through publications or a new international data repository would facilitate greater integration of current research with previous findings and ensure evidence is available to support the needs of the ageing population.

TRIAL REGISTRATION

Pregabalin versus placebo in targeting pro-nociceptive mechanisms to prevent chronic pain after whiplash injury in at-risk individuals - a feasibility study for a randomised controlled trial

BACKGROUND

Whiplash-associated disorders (WAD) are an enormous and costly burden to Australian society. Up to 50% of people who experience a whiplash injury will never fully recover. Whiplash is resistant to treatment and no early management approach has yet been shown to prevent chronic pain. The early presence of central sensitization is associated with poor recovery. Pregabalin's effects on central sensitization indicate the potential to prevent or modulate these processes after whiplash injury and to improve health outcomes, but this has not been investigated. This paper describes the protocol for a feasibility study for a randomised controlled trial of pregabalin plus evidence-based advice compared to placebo plus evidence-based advice for individuals with acute whiplash injury who are at risk of poor recovery.

METHODS

This double blind, placebo-controlled randomised feasibility study will examine the feasibility and potential effectiveness of pregabalin and evidence-based advice (intervention) compared to placebo and evidence-based advice (control) for individuals with acute whiplash injury at risk of poor recovery. Thirty participants (15 per group) aged 18-65 years with Grade II WAD, within 48 hours of injury and currently experiencing at least moderate pain (NRS: ≥ 5/10) will be recruited from Emergency Departments of public hospitals in Queensland, Australia. Pregabalin will be commenced at 75 mg bd and titrated up to 300 mg bd as tolerated for 4 weeks followed by 1 week of weaning.

RESULTS

The feasibility of trial procedures will be tested, as well as the potential effect of the intervention on the outcomes. The primary outcome of neck pain intensity at 3 months from randomisation will be compared between the treatment groups using standard analysis of variance techniques.

DISCUSSION

Feasibility and potential effectiveness data will inform an appropriately powered full trial, which if successful, will provide an effective and cost-effective intervention for a costly and treatment resistant condition. It will also have implications for the early management of other traumatic conditions beyond whiplash.

Exploring approaches to dietetic assessment of a common task across different universities through assessment moderation

BACKGROUND

Assessment presents one of the greatest challenges to evaluating health professional trainee performance, as a result of the subjectivity of judgements and variability in assessor standards. The present study aimed to test a moderation procedure for assessment across four independent universities and explore approaches to assessment and the factors that influence assessment decisions.

METHODS

Assessment tasks designed independently by each of the four universities to assess student readiness for placement were chosen for the present study. Each university provided four student performance recordings for moderation. Eight different academic assessors viewed the student performances and assessed them using the corresponding university assessment instrument. Assessment results were collated and presented back to the assessors, together with the original university assessment results. Results were discussed with assessors to explore variations. The discussion was recorded, transcribed, thematically analysed and presented back to all assessors to achieve consensus on the emerging major learnings.

RESULTS

Although there were differences in absolute scores, there was consistency (12 out of 16 performances) in overall judgement decisions regarding placement readiness. Proficient communication skills were considered a key factor when determining placement readiness. The discussion revealed: (i) assessment instruments; (ii) assessor factors; and (iii) the subjectivity of judgement as the major factors influencing assessment.

CONCLUSIONS

Assessment moderation is a useful method for improving the quality of assessment decisions by sharing understanding and aligning standards of performance.

Fall from heights: does height really matter?

INTRODUCTION

Fall from heights is high energy injuries and constitutes a fraction of all fall-related trauma evaluations while bearing an increase in morbidity and mortality. We hypothesize that despite advancements in trauma care, the overall survivability has not improved in this subset of trauma patients.

METHODS

All adult trauma patients treated after sustaining a fall from heights during a 40-month period were retrospectively reviewed. Admission demographics, clinical data, fall height (ft), injury patterns, ISS, GCS, length of stay, and mortality were reviewed.

RESULTS

116 patients sustained a fall from heights, 90.4% accidental. A mean age of 37± 14.7 years, 86% male, and a fall height of 19 ± 10 ft were encountered. Admission GCS was 13 ± 2 with ISS 10 ± 11. Overall LOS was 6.6 ± 14.9 days and an ICU LOS of 2.8 ± 8.9 days. Falls ≥ 25 ft.(16%) had lower GCS 10.4 ± 5.8, increased ISS 22.6 ± 13.8, a fall height 37.9 ± 13.1 ft and associated increased mortality (p < 0.001). Mortality was 5.2%, a mean distance fallen of 39 ± 22 ft. and an ISS of 31.5 ±16.5. Brain injury was the leading cause of death, 50% with open skull fractures.

CONCLUSION

Level of height fallen is a good predictor of overall outcome and survival. Despite advances in trauma care, death rates remain unchanged. Safety awareness and injury prevention programs are needed to reduce the risk of high-level falls.

Comparison of endoscopic laser therapy and self expanding metal stents for palliation in patients with non-resectable oesophageal carcinoma

BACKGROUND

There are currently limited data on the comparative success of endoscopic laser therapy (NLT) and self expanding metal stents (SEMS) as palliative measures in patients with non-resectable oesophageal cancer. This study aims to assess and compare the outcomes of these methods of endoscopic palliation.

METHODS

Patients with non-curative oesophageal/gastro-oesophageal cancers with dysphagia were identified prospectively and consented to swallow assessment and follow-up. Patients underwent SEMS or NLT at the discretion of the treating endoscopist. Initial standardised swallow scores (0-4) were assessed. All subsequent interventions were recorded as well as survival.

RESULTS

31 patients were recruited (30M vs 8F, mean age 70.8). There was no significant difference in age, sex or chemotherapy treatment between groups. 19(61%)patients underwent NLT as primary procedure. 20(64.5%) patients required subsequent intervention(s) (median 1, range 0-8). Primary NLT patients were more likely to require subsequent therapy (p = 0.004) and multiple procedures (p = 0.001). 8(42.1%)patients initially undergoing NLT subsequently required SEMS, while no SEMS patients underwent subsequent NLT. Swallow scores of 1 or 2 were more likely to be maintained with NLT while scores of 3 or 4 were more likely to progress to SEMS (p = 0.039). Time to repeat procedure was greater in the SEMS group (p = 0.001). Median survival was 133 days for NLT vs 60 days for SEMS (p = 0.412).

CONCLUSION

In this series, patients selected for NLT had a trend towards longer survival, but were more likely to require repeated procedures. Those with lower early initial dysphagia scores were more likely to be maintained by NLT alone.

Population-based cohort study of variation in the use of emergency cholecystectomy for benign gallbladder diseases

Background

The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals.

Methods

Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2).

Results

Data were collected on 4744 cholecystectomies from 165 hospitals. Increasing age, lower ASA fitness grade, biliary colic, the need for further imaging (magnetic retrograde cholangiopancreatography), endoscopic interventions (endoscopic retrograde cholangiopancreatography) and admission to a non-biliary centre significantly reduced the likelihood of an emergency cholecystectomy being performed. The multilevel model was used to calculate the probability of receiving an emergency cholecystectomy for a woman aged 40 years or over with an ASA grade of I or II and a BMI of at least 25·0 kg/m2, who presented with acute cholecystitis with an ultrasound scan showing a thick-walled gallbladder and a normal common bile duct. The mean predicted probability of receiving an emergency cholecystectomy was 0·52 (95 per cent c.i. 0·45 to 0·57). The predicted probabilities ranged from 0·02 to 0·95 across the 165 hospitals, demonstrating significant variation between hospitals.

Conclusion

Patients with similar characteristics presenting to different hospitals with acute gallbladder pathology do not receive comparable care.

Differential Cell Composition and Cytokine Expression Within Lymph Node Granulomas from BCG-Vaccinated and Non-vaccinated Cattle Experimentally Infected with Mycobacterium bovis

Cattle vaccination against bovine tuberculosis (bTB) has been proposed as a supplementary method to help control the incidences of this disease. Bacillus Calmette-Guérin (BCG) is currently the only viable candidate vaccine for immunization of cattle against bTB, caused by Mycobacterium bovis (M. bovis). In an attempt to characterize the differences in the immune response following M. bovis infection between BCG-vaccinated and non-vaccinated animals, a combination of gross pathology, histopathology and immunohistochemical (IHC) analyses was used. BCG vaccination was found to significantly reduce the number of gross and microscopic lesions present within the lungs and lymph nodes. Additionally, the microscopically visible bacterial load of stages III and IV granulomas was reduced. IHC using cell surface markers revealed the number of CD68+ (macrophages), CD3+ (T lymphocytes) and WC1+ cells (γδ T cells) to be significantly reduced in lymph node granulomas of BCG-vaccinated animals, when compared to non-vaccinated animals. B lymphocytes (CD79a+) were significantly increased in BCG-vaccinated cattle for granulomas at stages II, III and IV. IHC staining for iNOS showed a higher expression in granulomas from BCG-vaccinated animals compared to non-vaccinated animals for all stages, being statistically significant in stages I and IV. TGFβ expression decreased alongside the granuloma development in non-vaccinated animals, whereas BCG-vaccinated animals showed a slight increase alongside lesion progression. IHC analysis of the cytokines IFN-γ and TNF-α demonstrated significantly increased expression within the lymph node granulomas of BCG-vaccinated cattle. This is suggestive of a protective role for IFN-γ and TNF-α in response to M. bovis infection. Findings shown in this study suggest that the use of BCG vaccine can reduce the number and severity of lesions, induce a different phenotypic response and increase the local expression of key cytokines related to protection.

Tolerability and Adherence Problems in Patients on a Stable Dose of Methotrexate: Results of a Multicentre Survey

INTRODUCTION

Methotrexate is commonly used in patients with inflammatory arthritis. The aim of the present study was to ascertain the prevalence of side effects that patients on methotrexate were tolerating and to establish their adherence to the medication.

METHOD

A questionnaire was developed for completion by the healthcare professional with the patient, and piloted in one centre. The questionnaire was then used in six other centres, with the addition of a question about the attractiveness of stopping methotrexate treatment. Efficacy and toxicities were scored for severity on a 10-cm visual analogue scale (VAS). Adherence to the drug was also explored.

RESULTS

The prevalence of 'any side effect' ranged from 57% to 86%. The most frequent side effects were fatigue (53%); nausea (38%); mouth ulcers (23%) and hair loss (23%). Efficacy averaged 6.5 cm on the VAS. Results from the combined survey revealed that toxicity averaged 5.9 cm for fatigue, 4.8 cm for nausea, 4.4 for mouth ulcers, 3.9 cm for hair loss and 5.7 cm for 'other' side effects. 13.5% of patients revealed that they had forgotten to take the drug for an average of two weeks, and 25% for an average of 2.5 weeks in the previous year. Participants were more likely to reveal this to a nurse than a doctor.

CONCLUSION

Patients put up with a considerable number of side effects in order to benefit from methotrexate therapy. Adherence to this drug merits further study. Copyright © 2015 John Wiley & Sons, Ltd.
