Limited access to multiple sclerosis (MS)-focused care in rural areas can decrease the quality of life in individuals living with MS while influencing both physical and mental health.
Methods:
The objectives of this research were to compare demographic and clinical outcomes in participants with MS who reside within urban, semi-urban and rural settings within Newfoundland and Labrador. All participants were assessed by an MS neurologist, and data collection included participants’ clinical history, date of diagnosis, disease-modifying therapy (DMT) use, measures of disability, fatigue, pain, heat sensitivity, depression, anxiety and disease activity.
Results:
Overall, no demographic differences were observed between rural and urban areas. Furthermore, the categorization of primary residence did not demonstrate any differences in physical disability or indicators of disease activity. A significantly higher percentage of participants were prescribed platform or high-efficacy DMTs in semi-urban areas; a higher percentage of participants in urban and rural areas were prescribed moderate-efficacy DMTs. Compared to depression, anxiety was more prevalent within the entire cohort. Comparable levels of anxiety were measured across all areas, yet individuals in rural settings experienced greater levels of depression. Individuals living with MS in either an urban or rural setting demonstrated clinical similarities, which were relatively equally managed by DMTs.
Conclusion:
Despite greater levels of depression in rural areas, the results of this study highlight that an overall comparable level and continuity of care is provided to individuals living with MS within rural and urban Newfoundland and Labrador.
The diets of children in the UK are suboptimal(1), which may influence their immediate and future health and well-being(2). Schools offer convenient and prolonged access to children from diverse backgrounds, thus interventions within this setting have been suggested as a means to promote diet and health outcomes among this population(3). This study explored the effects of Project Daire(4), a school-based food intervention, on children’s diet diversity and diet quality as well as their attitudes towards health behaviours.
A factorial design cluster randomized controlled trial was conducted. Fifteen primary schools in Northern Ireland were randomized into one of four 6-month intervention arms: Nourish, Engage, Nourish and Engage or Control (Delayed). The Nourish intervention modified the school food environment, provided food-related experiences and increased access to local foods. The Engage intervention included educational activities on nutrition, food and agriculture. Data on food consumption at home, school and/or in total over a 24-hour period were collected using ageappropriate food frequency questionnaires at baseline, with follow-up at 6-months. Diet diversity score (DDS) and diet quality score (DQS) were developed based on adherence to the Eatwell Guide. Additionally, a Health Attitudes and Behaviour measure assessed 10-11 year old children’s attitudes towards importance of various health behaviours at both time points. Linear and logistic regression models were used to examine intervention effects and to account for school clustering.
A total of 445 children aged 6-7 and 458 aged 10-11 years old completed the trial. Results indicated that children aged 10-11 year old who received the Nourish intervention demonstrated higher school DDS (adjusted mean difference=2.79, 95% CI 1.40 – 4.19; p = 0.001) and total DDS (adjusted mean difference=1.55, 95% CI 0.66 – 2.43, p = 0.002) compared to their counterparts who did not. Subgroup analyses revealed that the increases in school DDS among 10-11 year old children in the Nourish group were apparent in both boys and girls (Boys: adjusted mean difference=2.4 95% CI 0.1 – 4.7, p = 0.04; Girls: adjusted mean difference=3.1 95% CI 1.6 – 4.6, p = 0.001). However, the increase in total DDS remained statistically significant only among girls, with an adjusted mean difference of 1.9 (95% CI 1.1-2.7, p<0.001). No statistically significant changes in DQS were detected in either age group. High levels of positive attitudes towards health behaviours were observed at baseline, with no clinically significant effects of either the Nourish or Engage interventions detected during the follow-up period.
The multi-component approach of the Nourish intervention, addressing both food provision and environment, showed promise in promoting diet diversity. Further research is warranted to develop sustainable implementation strategies for Daire, to explore additional intervention components to impact other outcomes, including diet quality, and to evaluate long-term effectiveness.
To compare rates of Clostridioides difficile infection (CDI) recurrence following initial occurrence treated with tapered enteral vancomycin compared to standard vancomycin.
Design:
Retrospective cohort study.
Setting:
Community health system.
Patients:
Adults ≥18 years of age hospitalized with positive C. difficile polymerase chain reaction or toxin enzyme immunoassay who were prescribed either standard 10–14 days of enteral vancomycin four times daily or a 12-week tapered vancomycin regimen.
Methods:
Retrospective propensity score pair matched cohort study. Groups were matched based on age < or ≥ 65 years and receipt of non-C. difficile antibiotics during hospitalization or within 6 months post-discharge. Recurrence rates were analyzed via logistic regression conditioned on matched pairs and reported as conditional odds ratios. The primary outcome was recurrence rates compared between standard vancomycin versus tapered vancomycin for treatment of initial CDI.
Results:
The CDI recurrence rate at 6 months was 5.3% (4/75) in the taper cohort versus 28% (21/75) in the standard vancomycin cohort. The median time to CDI recurrence was 115 days versus 20 days in the taper and standard vancomycin cohorts, respectively. When adjusted for matching, patients in the taper arm were less likely to experience CDI recurrence at 6 months when compared to standard vancomycin (cOR = 0.19, 95% CI 0.07–0.56, p < 0.002).
Conclusions:
Larger prospective trials are needed to elucidate the clinical utility of tapered oral vancomycin as a treatment option to achieve sustained clinical cure in first occurrences of CDI.
Background: Shared decision-making (SDM) is a dynamic, patient-engaged approach to collaborative medical care. Limited SDM tools exist in pregnancy. We aimed to examine the need and usability of a novel SDM tool for pharmaco-therapeutic treatment of neurological conditions in pregnancy. Methods: This is an exploratory mixed-methods study. Non-pregnant women of any age were recruited using convenience, purposive sampling from an academic neurology clinic in Toronto. Participants reported the user friendliness of the SDM by completing the systems usability (SUS) questionnaire and participated in a focus group to further elaborate on their experience. Results: Eleven participants completed the survey 45% each between age 31-40, and 51-60. Median time spent on the tool was 17.2 minutes, and median SUS score 70 (<68 being not usable). Thematic data analysis from 2 focus groups, identified technical and content improvements: use of inclusive language, simplified design, and importance of patient engagement in SDM. Conclusions: Based on our preliminary results, a SDM web-tool for medication-related concerns of pregnant patients with neurological conditions is needed and usable. With integration of patients’ lived experiences, this novel tool may serve as an anchor point for future work in this field.
The school food environment (SFE) is an ideal setting for encouraging healthy dietary behaviour. We aimed to develop an instrument to assess whole-SFE, test the instrument in the school setting and demonstrate its use to make food environment recommendations.
Design:
SFE literature and UK school food guidance were searched to inform instrument items. The instrument consisted of (i) an observation proforma capturing canteen areas systems, food presentation and monitoring of food intake and (ii) a questionnaire assessing food policies, provision and activities. The instrument was tested in schools and used to develop SFE recommendations. Descriptive analyses enabled narrative discussion.
Setting:
Primary schools.
Participants:
An observation was undertaken at schools in urban and rural geographical regions of Northern Ireland of varying socio-economic status (n 18). School senior management completed the questionnaire with input from school caterers (n 16).
Results:
The instrument captured desired detail and potential instrument modifications were identified. SFE varied. Differences existed between food policies and how policies were implemented and monitored. At many schools, there was scope to enhance physical eating environments (n 12, 67 %) and food presentation (n 15, 83 %); emphasise healthy eating through food activities (n 7, 78 %) and increase parental engagement in school food (n 9, 56 %).
Conclusions:
The developed instrument can measure whole-SFE in primary schools and also enabled identification of recommendations to enhance SFE. Further assessment and adaptation of the instrument are required to enable future use as a research tool or for self-assessment use by schools.
Neuropsychiatric disorders are common in 22q11.2 Deletion Syndrome (22q11DS) with about 25% of affected individuals developing schizophrenia spectrum disorders by young adulthood. Longitudinal evaluation of psychosis spectrum features and neurocognition can establish developmental trajectories and impact on functional outcome.
Methods
157 youth with 22q11DS were assessed longitudinally for psychopathology focusing on psychosis spectrum symptoms, neurocognitive performance and global functioning. We contrasted the pattern of positive and negative psychosis spectrum symptoms and neurocognitive performance differentiating those with more prominent Psychosis Spectrum symptoms (PS+) to those without prominent psychosis symptoms (PS−).
Results
We identified differences in the trajectories of psychosis symptoms and neurocognitive performance between the groups. The PS+ group showed age associated increase in symptom severity, especially negative symptoms and general nonspecific symptoms. Correspondingly, their level of functioning was worse and deteriorated more steeply than the PS− group. Neurocognitive performance was generally comparable in PS+ and PS− groups and demonstrated a similar age-related trajectory. However, worsening executive functioning distinguished the PS+ group from PS− counterparts. Notably, of the three executive function measures examined, only working memory showed a significant difference between the groups in rate of change. Finally, structural equation modeling showed that neurocognitive decline drove the clinical change.
Conclusions
Youth with 22q11DS and more prominent psychosis features show worsening of symptoms and functional decline driven by neurocognitive decline, most related to executive functions and specifically working memory. The results underscore the importance of working memory in the developmental progression of psychosis.
Peer support interventions for dietary change may offer cost-effective alternatives to interventions led by health professionals. This process evaluation of a trial to encourage the adoption and maintenance of a Mediterranean diet in a Northern European population at high CVD risk (TEAM-MED) aimed to investigate the feasibility of implementing a group-based peer support intervention for dietary change, positive elements of the intervention and aspects that could be improved. Data on training and support for the peer supporters; intervention fidelity and acceptability; acceptability of data collection processes for the trial and reasons for withdrawal from the trial were considered. Data were collected from observations, questionnaires and interviews, with both peer supporters and trial participants. Peer supporters were recruited and trained to result in successful implementation of the intervention; all intended sessions were run, with the majority of elements included. Peer supporters were complimentary of the training, and positive comments from participants centred around the peer supporters, the intervention materials and the supportive nature of the group sessions. Attendance at the group sessions, however, waned over the intervention, with suggested effects on intervention engagement, enthusiasm and group cohesion. Reduced attendance was reportedly a result of meeting (in)frequency and organisational concerns, but increased social activities and group-based activities may also increase engagement, group cohesion and attendance. The peer support intervention was successfully implemented and tested, but improvements can be suggested and may enhance the successful nature of these types of interventions. Some consideration of personal preferences may also improve outcomes.
In this study, we evaluated the impact of a microbiology nudge on de-escalation to first-generation cephalosporins in hospitalized patients with urinary tract infections secondary to Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis isolates with minimum inhibitory concentrations (MICs) ≤ 16 µg/mL. De-escalation to first generation-cephalosporins was uncommon at MICs = 4–16 µg/mL.
To determine how engagement of the hospital and/or vendor with performance improvement strategies combined with an automated hand hygiene monitoring system (AHHMS) influence hand hygiene (HH) performance rates.
The study was conducted in 58 adult and pediatric inpatient units located in 10 hospitals.
Methods:
HH performance rates were estimated using an AHHMS. Rates were expressed as the number of soap and alcohol-based hand rub portions dispensed divided by the number of room entries and exits. Each hospital self-assigned to one of the following intervention groups: AHHMS alone (control group), AHHMS plus clinician-based vendor support (vendor-only group), AHHMS plus hospital-led unit-based initiatives (hospital-only group), or AHHMS plus clinician-based vendor support and hospital-led unit-based initiatives (vendor-plus-hospital group). Each hospital unit produced 1–2 months of baseline HH performance data immediately after AHHMS installation before implementing initiatives.
Results:
Hospital units in the vendor-plus-hospital group had a statistically significant increase of at least 46% in HH performance compared with units in the other 3 groups (P ≤ .006). Units in the hospital only group achieved a 1.3% increase in HH performance compared with units that had AHHMS alone (P = .950). Units with AHHMS plus other initiatives each had a larger change in HH performance rates over their baseline than those in the AHHMS-alone group (P < 0.001).
Conclusions:
AHHMS combined with clinician-based vendor support and hospital-led unit-based initiatives resulted in the greatest improvements in HH performance. These results illustrate the value of a collaborative partnership between the hospital and the AHHMS vendor.
To investigate associations between multimodal analgesia and post-operative pain among patients undergoing transoral robotic surgery for oropharyngeal squamous cell carcinoma.
Methods
Records of patients who underwent surgery from 5 September 2012 to 30 November 2016 were abstracted. Associations were assessed using multivariable analysis.
Results
A total of 216 patients (mean age of 59.1 years, 89.4 per cent male) underwent transoral robotic surgery (92.6 per cent were human papilloma virus positive, 87.5 per cent had stage T1–T2 tumours, and 82.9 per cent had stage N0–N1 nodes). Gabapentin (n = 86) was not associated with a reduction in severe pain. Ibuprofen (n = 72) was administered less often in patients with severe pain. Gabapentin was not associated with increased post-operative sedation (p = 0.624) and ibuprofen was not associated with increased bleeding (p = 0.221). Post-operative opioid usage was not associated with surgical duration, pharyngotomy, bilateral neck dissections, tumour stage, tumour size, subsite or gabapentin.
Conclusion
Scheduled low-dose gabapentin was not associated with improved pain control or increased respiratory depression. Ibuprofen was not associated with an increased risk of bleeding and may be under-utilised.
This study aimed to evaluate the feasibility of a peer support intervention to encourage adoption and maintenance of a Mediterranean diet (MD) in established community groups where existing social support may assist the behaviour change process. Four established community groups with members at increased Cardiovascular Disease (CVD) risk and homogenous in gender were recruited and randomised to receive either a 12-month Peer Support (PS) intervention (PSG) (n 2) or a Minimal Support intervention (educational materials only) (MSG) (n 2). The feasibility of the intervention was assessed using recruitment and retention rates, assessing the variability of outcome measures (primary outcome: adoption of an MD at 6 months (using a Mediterranean Diet Score (MDS)) and process evaluation measures including qualitative interviews. Recruitment rates for community groups (n 4/8), participants (n 31/51) and peer supporters (n 6/14) were 50 %, 61 % and 43 %, respectively. The recruitment strategy faced several challenges with recruitment and retention of participants, leading to a smaller sample than intended. At 12 months, a 65 % and 76·5 % retention rate for PSG and MSG participants was observed, respectively. A > 2-point increase in MDS was observed in both the PSG and the MSG at 6 months, maintained at 12 months. An increase in MD adherence was evident in both groups during follow-up; however, the challenges faced in recruitment and retention suggest a definitive study of the peer support intervention using current methods is not feasible and refinement based on the current feasibility study should be incorporated. Lessons learned during the implementation of this intervention will help inform future interventions in this area.
Ecosystem modeling, a pillar of the systems ecology paradigm (SEP), addresses questions such as, how much carbon and nitrogen are cycled within ecological sites, landscapes, or indeed the earth system? Or how are human activities modifying these flows? Modeling, when coupled with field and laboratory studies, represents the essence of the SEP in that they embody accumulated knowledge and generate hypotheses to test understanding of ecosystem processes and behavior. Initially, ecosystem models were primarily used to improve our understanding about how biophysical aspects of ecosystems operate. However, current ecosystem models are widely used to make accurate predictions about how large-scale phenomena such as climate change and management practices impact ecosystem dynamics and assess potential effects of these changes on economic activity and policy making. In sum, ecosystem models embedded in the SEP remain our best mechanism to integrate diverse types of knowledge regarding how the earth system functions and to make quantitative predictions that can be confronted with observations of reality. Modeling efforts discussed are the Century ecosystem model, DayCent ecosystem model, Grassland Ecosystem Model ELM, food web models, Savanna model, agent-based and coupled systems modeling, and Bayesian modeling.
Evidence suggests that dietary intake of UK children is currently suboptimal. It is therefore imperative to identify effective and sustainable methods of improving dietary habits and knowledge in this population, whilst also promoting the value of healthiness of food products beyond price. Schools are ideally placed to influence children's knowledge and health, and Project Daire, in partnership with schools, food industry partners and stakeholders, aims to improve children's knowledge of, and interest in, food to improve health, wellbeing and educational attainment.
Daire is a randomised-controlled, factorial design trial evaluating two interventions. In total, n = 880 Key Stage (KS) 1 and 2 pupils have been recruited from 18 primary schools in the North West of Northern Ireland and will be randomised to one of four 6-month intervention arms: i) ‘Engage’, ii) ‘Nourish’, iii) ‘Engage’ and ‘Nourish’ and iv) Delayed. ‘Engage’ is an age-appropriate, cross-curricular educational intervention on food, agriculture, science and careers linked to the current curriculum. ‘Nourish’ is an intervention aiming to alter schools’ food environments and increase exposure to local foods. Study outcomes include food knowledge, attitudes, trust, diet, behaviour, health and wellbeing and will be collected at baseline and six months. Qualitative data on teacher/pupil opinions will also be collected. The intervention phase is currently ongoing. We present baseline results from our involvement and food attitudes measure from all participating schools. Results were compared by Key Stage and sex using Pearson Chi-Squared test.
Baseline results from our food involvement and attitudes measure are presented for n = 880 KS1 (n = 454) and KS2 (n = 426) pupils. KS1 pupils were more likely to always or sometimes help with food shopping (89.0%) whilst KS2 pupils were more likely to always or sometimes help with food preparation (69.0%). A higher proportion of KS1 pupils reported liking to try new foods (66.1%) and that it was important that food looked (64.5%), tasted (71.1%) and smelled good (60.6%) compared with KS2 children (P < 0.01). Girls were more likely to always or sometimes help with food shopping (96.2%) and preparation (73%) when compared with boys; whilst a higher proportion of girls reported they liked to try new foods (48.2%) and that it was important that food looked (68%) smelled (50.5%) and tasted (71.8%) good compared with boys (P < 0.01).
Results suggest that involvement in food preparation and shopping, willingness to try new foods and attitudes towards food presentation varied by KS and sex in this cohort.
Objective. To identify clinically useful predictors of adherence to medication among persons with schizophrenia. Method. We evaluated levels of compliance with neuroleptic medication among 32 consecutive admissions with DSM-III-R schizophrenia from a geographically defined catchment area using a compliance interview. We also assessed symptomatology, insight, neurological status and memory. Results. Less than 25% of consecutive admissions reported being fully compliant. Drug attitudes were the best predictor of regular compliance, symptomatology the best predictor of noncompliance, and memory the best predictor of partial compliance with neuroleptic medication. Conclusions. These data emphasise the complexity of factors that influence whether a person adheres to his medication regimen. Furthermore, they suggest that these factors may vary within the same person over time.
The rocky shores of the north-east Atlantic have been long studied. Our focus is from Gibraltar to Norway plus the Azores and Iceland. Phylogeographic processes shape biogeographic patterns of biodiversity. Long-term and broadscale studies have shown the responses of biota to past climate fluctuations and more recent anthropogenic climate change. Inter- and intra-specific species interactions along sharp local environmental gradients shape distributions and community structure and hence ecosystem functioning. Shifts in domination by fucoids in shelter to barnacles/mussels in exposure are mediated by grazing by patellid limpets. Further south fucoids become increasingly rare, with species disappearing or restricted to estuarine refuges, caused by greater desiccation and grazing pressure. Mesoscale processes influence bottom-up nutrient forcing and larval supply, hence affecting species abundance and distribution, and can be proximate factors setting range edges (e.g., the English Channel, the Iberian Peninsula). Impacts of invasive non-native species are reviewed. Knowledge gaps such as the work on rockpools and host–parasite dynamics are also outlined.
There is an urgent need to find effective methods of supporting individuals to make dietary behaviour changes. Peer-supported interventions (PSI) have been suggested as a cost-effective strategy to support chronic disease self-management. However, the effect of PSI on dietary behaviour is unclear. The present systematic review aimed to assess the effectiveness of PSI for encouraging dietary behaviour change in adults and to consider intervention characteristics linked with effectiveness.
Design
Electronic databases were searched until June 2018 for randomised controlled trials assessing the effectiveness of PSI compared with an alternative intervention and/or control on a dietary related outcome in adults. Following title and abstract screening, two reviewers independently screened full texts and data were extracted by one reviewer and independently checked by another. Results were synthesised narratively.
Setting
Randomised controlled trials.
Participants
Adult studies.
Results
The fifty-four included studies varied in participants, intervention details and results. More PSI reported a positive or mixed effect on diet than no effect. Most interventions used a group model and were lay-led by peer supporters. Several studies did not report intervention intensity, fidelity and peer training and support in detail. Studies reporting positive effects employed more behaviour change techniques (BCT) than studies reporting no effect; however, heterogeneity between studies was considerable.
Conclusions
As evidence was mixed, further interventions need to assess the effect of PSI on dietary behaviour, describe intervention content (theoretical basis, BCT, intensity and peer training/support) and include a detailed process evaluation.
