Dietary nitrate is a precursor to nitric oxide, for which plausible mechanisms exist for both beneficial and detrimental influences in multiple sclerosis (MS)(1,2). Whether dietary nitrate has any role in MS onset is unclear. We aimed to test associations between nitrate intake from food sources (plant, vegetable, animal, processed meat, and unprocessed meat) and likelihood of a first clinical diagnosis of central nervous system demyelination (FCD). We used data from the Ausimmune Study (264 cases, 474 controls). Case participants (aged 19–59 years) presenting to medical professionals in four latitudinally different regions of Australia were referred to the study with an FCD. The Australian Electoral Roll was used to recruit one to four controls per case, matched by age (± 2 years), sex and study region. Habitual dietary intake representing the 12-month period preceding the study interview was assessed to determine dietary nitrate intake. In addition to matching variables, data on education, smoking history, and history of infectious mononucleosis, weight and height were collected. A blood sample was taken for measurement of serum 25-hydroxyvitamin D concentration, which was de-seasonalised. To test associations, we used logistic regression with full propensity score matching. We used two levels of covariate matching: in model 1, cases and controls were matched on the original matching variables (age, sex, and study region); in model 2, cases and controls were additionally matched on well-established/potential risk factors for MS (education, smoking history, and history of infectious mononucleosis) and dietary factors (total energy intake and dietary misreporting). In females only (n = 573; 368 controls and 205 cases), higher nitrate intake (per 60 mg/day) from plant-based foods (fully adjusted odds ratio [aOR] = 0.50, 95% CI, 0.31, 0.81, p < 0.01) or vegetables (aOR = 0.44, 95% CI, 0.27, 0.73, p < 0.01) was statistically significantly associated with lower likelihood of FCD. No association was found between nitrate intake (any sources) and likelihood of FCD in males. To our knowledge, this is the first study to investigate dietary nitrate intake in relation to FCD. Our result that higher intake of nitrate from plant-based foods (mainly vegetables) was associated with lower likelihood of FCD in females supports our previous findings showing that following a Mediterranean diet (rich in vegetables) associates with lower likelihood of FCD(3). The lack of association in males may be due to low statistical power and/or differing food preferences and pathological processes among males and females. Our results support further research to delineate the independent effect of nitrates form other dietary factors and explore a possible beneficial role for plant-derived nitrate in people at high risk of MS.
Guideline-based tobacco treatment is infrequently offered. Electronic health record-enabled patient-generated health data (PGHD) has the potential to increase patient treatment engagement and satisfaction.
Methods:
We evaluated outcomes of a strategy to enable PGHD in a medical oncology clinic from July 1, 2021 to December 31, 2022. Among 12,777 patients, 82.1% received a tobacco screener about use and interest in treatment as part of eCheck-in via the patient portal.
Results:
We attained a broad reach (82.1%) and moderate response rate (30.9%) for this low-burden PGHD strategy. Patients reporting current smoking (n = 240) expressed interest in smoking cessation medication (47.9%) and counseling (35.8%). As a result of patient requests via PGHD, most tobacco treatment requests by patients were addressed by their providers (40.6–80.3%). Among patients with active smoking, those who received/answered the screener (n = 309 ) were more likely to receive tobacco treatment compared with usual care patients who did not have the patient portal (n = 323) (OR = 2.72, 95% CI = 1.93–3.82, P < 0.0001) using propensity scores to adjust for the effect of age, sex, race, insurance, and comorbidity. Patients who received yet ignored the screener (n = 1024) compared with usual care were also more likely to receive tobacco treatment, but to a lesser extent (OR = 2.20, 95% CI = 1.68–2.86, P < 0.0001). We mapped observed and potential benefits to the Translational Science Benefits Model (TSBM).
Discussion:
PGHD via patient portal appears to be a feasible, acceptable, scalable, and cost-effective approach to promote patient-centered care and tobacco treatment in cancer patients. Importantly, the PGHD approach serves as a real world example of cancer prevention leveraging the TSBM.
Despite high UVB radiation from the sun in Australia (the primary source of vitamin D), vitamin D deficiency (serum 25-hydroxyvitamin D concentrations [25(OH)D] <50 nmol/L) is prevalent among Aboriginal and Torres Strait Islander peoples (27% of adults nationally; 39% of adults living in remote areas)(1). Vitamin D deficiency affects musculoskeletal health and may be associated with non-communicable diseases, such as type 2 diabetes and cardiovascular diseases, prevalent in Aboriginal and Torres Strait Islander peoples.(2, 3) Alternative to UVB radiation, vitamin D can also be obtained from foods (e.g., fish, eggs, and meat) and supplements. However, vitamin D intake in Aboriginal and Torres Strait Islander peoples is currently unknown. Hence, we aimed to provide the first estimate of absolute vitamin D intake in Aboriginal and Torres Strait Islander peoples. We used food consumption data from the 2012-2013 National Aboriginal and Torres Strait Islander Nutrition and Physical Activity Survey and vitamin D food composition data for vitamin D3, 25(OH)D3, vitamin D2, and 25(OH)D2. Absolute vitamin D intake was estimated by sex and remote and non-remote areas using bioactivity factors (BF) of 1 and 5 for 25(OH)D, which may be up to five times more bioactive than vitamin D. The estimated average requirement for vitamin D intake recommended by the Institute of Medicine is 10 μg/day(4). The estimated absolute vitamin D intake from food and beverages was low for Aboriginal and Torres Strait Islander peoples. The mean estimated absolute vitamin D intake of Aboriginal and Torres Strait Islander peoples was 2.9 μg/day and 5.3 μg/day for BF 1 and 5, respectively. Males had a higher mean intake (3.2 μg/day, BF 1 and 5.9 μg/day, BF 5) than females (2.6 μg/day, BF 1 and 4.7 μg/day, BF 5). Vitamin D intake was 2.9 μg/day (BF 1) and 5.2 μg/day (BF 5) in non-remote and 2.8 μg/day (BF 1) and 5.4 μg/day (BF 5) in remote areas. The high prevalence of vitamin D deficiency and low vitamin D intake highlights a need to promote vitamin D sufficiency through public health policies. The results from this study can be used to model food fortification strategies to provide evidence for the development of nutrition policies to improve the vitamin D status of the Aboriginal and Torres Strait Islander population.
Telehealth overcomes common geographical barriers to community/clinic-based healthcare and lifestyle interventions, (1,2) but whether it is a feasible and safe mode of healthcare service delivery for lifestyle-based interventions in those with non-alcoholic fatty liver disease (NAFLD) remains unknown. This study evaluated the feasibility and safety of a home exercise program with dietary advice to increase plant-based protein delivered and monitored by healthcare professionals via telehealth in adults with NAFLD. Secondary aims were to assess changes in macronutrient intake including protein from plant and animal sources, body weight, physical activity and physical function. This was a 12-week pilot feasibility randomised controlled trial conducted in 28 inactive adults (>45 years) with NAFLD. Participants were randomly allocated to receive: 1) a home-based, muscle strengthening exercise program (3 days/week) delivered and monitored remotely by an exercise physiologist using the TeleHab exercise platform/app (VALD Health) plus support from a nutritionist to increase daily protein intake to ~1.2-1.5 g/kg/day from predominately plant-based sources and behavioural change support delivered via 3-4 weekly text messages (Pro-Ex, n = 14) or 2) usual care (UC, n = 14). Feasibility was assessed via retention (defined as ≤10% attrition), adherence [≥66% to the muscle strengthening program and ≥80% to the recommended daily protein serves [total (≥3-3½), plant (≥2) and animal (≤1-1½) per day (via protein checklist)] and safety (intervention-related adverse events). Secondary outcomes included macronutrient intake (3x24-hour records), weight (self-reported), habitual physical activity (PA) [moderate-to-vigorous (MVPA), minutes/week via the Short International Physical Activity Questionnaire], and physical function [30-second sit-to-stand (STS) performance]. Since this was a pilot feasibility study, mean group differences (6 and 12-weeks) were estimated, with 95% confidence intervals, and standardised effects [Cohen D, effect size (ES)] reported for secondary outcomes. Overall, 25 participants (89%) completed the intervention. In Pro-Ex, mean adherence to the exercise program was 52%, while adherence to the recommended plant, animal and total protein serves/day was 32%, 42% and 14% of participants, respectively. One minor exercise-related adverse event occurred from 241 completed sessions over 12 weeks. Relative to UC, Pro-Ex experienced a mean 2.7 (95%CI: 0.9, 4.4; large ES d = 1.29) increase in 30-sec STS number, 46 minute (95%CI: −153, 245; small ES d = 0.19) increase in MVPA, 1.7kg (95%CI: −3.5, 0.2; moderate ES d = 0.54) decrease in body weight, 35.2g (95%CI: 11.0, 59.3; large ES d = 1.23) increase in protein and 8.3g (95%CI:-20.5, 4.0; moderate ES d=-0.57) reduction in saturated fat. In middle-aged and older adults with NAFLD, a home exercise and plant-based dietary protein intervention delivered via telehealth was safe, but not feasible in terms of achieving the desired level of adherence. Despite this, exploratory analysis indicates this mode of healthcare service delivery could play a role to support weight management and improve physical activity and physical function in adults with NAFLD.
Hard-to-treat childhood cancers are those where standard treatment options do not exist and the prognosis is poor. Healthcare professionals (HCPs) are responsible for communicating with families about prognosis and complex experimental treatments. We aimed to identify HCPs’ key challenges and skills required when communicating with families about hard-to-treat cancers and their perceptions of communication-related training.
Methods
We interviewed Australian HCPs who had direct responsibilities in managing children/adolescents with hard-to-treat cancer within the past 24 months. Interviews were analyzed using qualitative content analysis.
Results
We interviewed 10 oncologists, 7 nurses, and 3 social workers. HCPs identified several challenges for communication with families including: balancing information provision while maintaining realistic hope; managing their own uncertainty; and nurses and social workers being underutilized during conversations with families, despite widespread preferences for multidisciplinary teamwork. HCPs perceived that making themselves available to families, empowering them to ask questions, and repeating information helped to establish and maintain trusting relationships with families. Half the HCPs reported receiving no formal training for communicating prognosis and treatment options with families of children with hard-to-treat cancers. Nurses, social workers, and less experienced oncologists supported the development of communication training resources, more so than more experienced oncologists.
Significance of results
Resources are needed which support HCPs to communicate with families of children with hard-to-treat cancers. Such resources may be particularly beneficial for junior oncologists and other HCPs during their training, and they should aim to prepare them for common challenges and foster greater multidisciplinary collaboration.
Early studies of common mental disorders (CMDs) during the COVID-19 pandemic mainly report increases; however, more recent findings have been mixed. Also, studies assessing the effects of restriction measures on CMDs show varied results. The aim of this meta-analysis was to assess changes in levels of CMDs from pre-/early to during the pandemic and the effects of restriction policies in the European population.
Methods
We searched for studies assessing both pre-pandemic and peri-pandemic self-reported emotional distress and symptoms of depression or anxiety among nationally/regionally representative samples in Europe and collected microdata from those studies. Estimates of corona containment index were related to changes in CMDs using random-effects meta-regression.
Results
Our search strategy resulted in findings from 15 datasets drawn from 8 European countries being included in the meta-analysis. There was no evidence of change in the prevalence of emotional distress, anxiety, or depression from before to during the pandemic; but from early pandemic periods to later periods, there were significant decreases in emotional distress and anxiety. Increased school restrictions and social distancing were associated with small increases in self-reported emotional distress.
Conclusions
Despite initial concerns of increased emotional distress and mental illness due to the COVID-19 pandemic, the results from this meta-analysis indicate that there was a decrease in emotional distress and no change in anxiety or depression in the general population in Europe. Overall, our findings support the importance of strong governance when implementing periodic and robust restriction measures to combat the spread of COVID-19.
This study focused on a jellyfish monitoring and sampling programme along the eastern Qatar seawaters and reports the first jellyfish records for the Qatar pelagic ecosystem and the occurrence of three scyphozoans: the semaeostome Chrysaora cf. caliparea and the rhizostomes Marivagia stellata and Catostylus perezi, considered as first records of Scyphomedusae for Qatar. Jellyfish monitoring, underwater photography and sample collection were carried out along an inshore-offshore transect composed of five stations along the eastern coast of Qatar. Jellyfish material examined, systematic description, general distribution and sting risk of the three species are provided. The discussion section highlights the blooming capabilities of Chrysaora cf. caliparea and Catostylus perezi, while Marivagia stellata seems scarcer, being spotted for the first time since we started our jellyfish investigation programme in August 2018.
Offspring exposed to prenatal maternal depression (PMD) are vulnerable to depression across their lifespan. The underlying cause(s) for this elevated intergenerational risk is most likely complex. However, depression is underpinned by a dysfunctional frontal-limbic network, associated with core information processing biases (e.g. attending more to sad stimuli). Aberrations in this network might mediate transmission of this vulnerability in infants exposed to PMD. In this study, we aimed to explore the association between foetal exposure to PMD and frontal-limbic network function in infancy, hypothesising that, in response to emotional sounds, infants exposed to PMD would exhibit atypical activity in these regions, relative to those not exposed to PMD.
Method
We employed a novel functional magnetic resonance imaging sequence to compare brain function, whilst listening to emotional sounds, in 78 full-term infants (3–6 months of age) born to mothers with and without a diagnosis of PMD.
Results
After exclusion of 19 datasets due to infants waking up, or moving excessively, we report between-group brain activity differences, between 29 infants exposed to PMD and 29 infants not exposed to PMD, occurring in temporal, striatal, amygdala/parahippocampal and frontal regions (p < 0.005). The offspring exposed to PMD exhibited a relative increase in activation to sad sounds and reduced (or unchanged) activation to happy sounds in frontal-limbic clusters.
Conclusions
Findings of a differential response to positive and negative valanced sounds by 3–6 months of age may have significant implications for our understanding of neural mechanisms that underpin the increased risk for later-life depression in this population.
To examine the impact of the first full year of the COVID-19 pandemic and its associated restrictions on the volume and nature of psychiatric presentations to an emergency department (ED) in a large academic hospital.
Methods:
Anonymised clinical data on psychiatric presentations to the ED were collected for the 52-week period from the start of the COVID-19 pandemic and compared with corresponding 1 year periods in 2019 and 2018.
Results:
There was a significant increase in psychiatric presentations overall to the ED during the first year of the COVID-19 pandemic compared to previous years, in contrast to a reduction in total presentations for all other specialties. There was a marked increase in psychiatric presentations of those below 18 years, and in the 30–39 years and 40–49 years age groups, but a decrease in the 18–29 years group. There was a significant increase in anxiety disorder presentations but a decrease in alcohol related presentations. There was no significant change observed in the rates of presentations for self-harm or suicidal ideation.
Conclusions:
Psychiatric presentations to the ED have increased during the first year of the COVID-19 pandemic in contrast to a decrease in presentations for other medical specialties, with this increase being driven by out-of-hours presentations. The fourfold increase in presentations of young people below the age of 18 years to the ED with mental health difficulties is an important finding and suggests a disproportionate burden of psychological strain placed on this group during the pandemic.
A Canadian health authority implemented a multisectoral intervention designed to control severe acute respiratory coronavirus virus 2 (SARS-CoV-2) transmission during long-term care facility (LTCF) outbreaks. The primary objective was to evaluate the effectiveness of the intervention 14 days after implementation.
A series of outbreak measures classified into 4 categories: case and contact management, proactive case detection, rigorous infection control practices and resource prioritization and stewardship.
Methods:
A mixed-effects segmented Poisson regression model was fitted to the incidence rate of coronavirus disease 2019 (COVID-19), calculated every 2 days, within each facility and case type (staff vs residents). For each facility, the outbreak time period was segmented into an early outbreak period (within 14 days of the intervention) and postintervention period (beyond 14 days following the intervention). Model outputs quantified COVID-19 incidence trend and rate changes between these 2 periods. A secondary model was constructed to identify effect modification by case type.
Results:
The significant upward trend in COVID-19 incidence rate during the early outbreak period (rate ratio [RR], 1.07; 95% confidence interval [CI], 1.03–1.11; P < .001) reversed during the postintervention period (RR, 0.73; 95% CI, 0.67–0.80; P < .001). The average trend did not differ by case type during the early outbreak period (P > .05) or the postintervention period (P > .05). However, staff had a 70% larger decrease in the average rate of COVID-19 during the postintervention period than residents (RR, 0.30; 95% CI, 0.10–0.88; P < .05).
Conclusions:
Our study provides evidence for the effectiveness of this intervention to reduce the transmission of COVID-19 in LTCFs. This intervention can be adapted and utilized by other jurisdictions to protect the vulnerable individuals in LTCFs.
There is limited knowledge of how individuals reflect on their involuntary admission.
Objectives
To investigate, at one year after an involuntary admission,
(i) peoples perception of the necessity of their involuntary admission
(ii) the enduring impact on the relationship with their family, consultant psychiatrist and employment prospects
(iii) readmission rates to hospital and risk factors for readmission.
Methods
People that were admitted involuntarily over a 15 month period were re-interviewed at one year following discharge.
Results
Sixty eight people were re-interviewed at one year and this resulted in a follow-up rate of 84%. Prior to discharge, 72% of people reported that their involuntary admission had been necessary however this reduced to 60% after one year. Over one third of people changed their views and the majority of these patients reflected negatively towards their involuntary admission.
One quarter of people continued to experience a negative impact on the relationship with a family member and their consultant psychiatrist one year after an involuntary admission, while 13% reported a positive impact. A similar proportion perceived that it had negative consequences in their employment.
Within one year, 43% of all patients involuntarily admitted in the study period were readmitted to hospital and half of these admissions were involuntary. Involuntary readmission was associated with a sealing over recovery style.
Conclusions
Peoples’ perception of the necessity of their involuntary admissions changes significantly over time. Involuntary admissions can have a lasting negative impact on the relationship with family members and treating consultant psychiatrist.
To obtainconsensus from non-consultant hospital doctors and consultants indeveloping a eLearning module for teaching non-consultant hospital doctorsabout delirium
Methods
1) A questionnaire to assess knowledge regarding deliriumwas administered to Medical NCHDs and toPsychiatry NCHDs. A 50 minute teaching session was provided to the PsychiatryNCHDs, which included an existing e-learning module for undergraduateson delirium developed in University College Dublin(UCD). Followingthis feedback was obtained regarding the module and what changes would berequired for it to meet the training needs of non consultant hospital doctors.
2) In the first step of the DELPHIprocess, feedback from medical consultants was obtained in relation to thethemes and topics to be included in the delirium e-learning module.
Results
•In the first iteration of the DELPHI process, both NCHDs and Consultants identified relevant learning outcomes for an eLearning module on delirium for postgraduate medical trainees.
Conclusion
The next iteration of the DELPHI process will refine the themespreviously identified in order to achieve consensus among the NCHD andconsultant groups surveyed. This will be the basis for the design of aneLearning module about delirium.
The early and efficacious detection of neurocognitive disorders poses a key diagnostic challenge. We examined how bedside cognitive tests perform across the spectrum of delirium and motor subtypes.
Methods
The performance on a battery of bedside cognitive tests were compared in elderly medical inpatients with DSM-IV delirium, subsyndromal delirium, and no neuro cognitive disorder and in motor subtypes.
Results
One hundred and ninety-eight patients (mean age 79.14 ± 8.26) were assessed with no delirium (n = 43), subsyndromal delirium (n = 45), and full syndromal delirium (n = 110). The ability to meaningfully engage with the tests varied from 59% for vigilance B test to 85% for Spatial Span forward test and was found to be least in the full syndromal delirium group. The no delirium group was distinguished from the delirium groups for all the tests and from the full syndromal delirium group for the vigilance B test and global visuospatial function test. The subsyndromal delirium group differed from the full syndromal delirium group in respect of global visuospatial function test, spatial span backwards and vigilance A tests. Patients with full syndromal delirium were best identified using the interlocking pentagons test and clock drawing test whereas those with subsyndromal delirium were best identified using interlocking pentagons test and months backwards test. Those with subsyndromal delirium were significantly better in their ability to engage than those with full syndromal delirium.
Conclusions
Simple bedside tests of attention, vigilance, and visuospatial ability are useful to help to distinguish neurocognitive disorders namely subsyndromal delirium from other presentations.

The most common intervention performed by physicians is the writing of a prescription. All elements in the complex process of prescribing and administering drugs are susceptible to error.
Aims
To measure the extent to which information recorded on prescription cards conforms to basic standards of prescription writing.
To improve prescribing, recording and staff knowledge.
To identify common prescribing errors and focus on the same to improve our standard of practice.
Methods
An audit tool was designed to collect data and standard was set 100%.
Results
In the initial audit, there was significant deficiency in prescription writing, which was presented at the internal teaching to all doctors and recommendations were made. This audit was repeated after a month, which showed improvement in prescription writing and recording.
Recommendations
Write all drugs in CAPITALS ensuring correct spelling, dose, route of administration and frequency.
Complete all fields on front of the prescription card legibly.
Document any change in prescription card in clinical notes.
All doctors to go through their current clients medication cards and ensure any gaps filled and errors corrected.
Audit report will be kept in audit folder as a reference for any rotating doctor to repeat the audit every six months in the services.
Conclusion
Doctors should continue to improve prescription writing and reduce any adverse events or errors.

The early and efficacious detection of neurocognitive disorders poses a key diagnostic challenge. We examined how nine bedside cognitive tests perform across the spectrum of delirium and motor subtypes.
Methods
The performance on a battery of nine bedside cognitive tests were compared in elderly medical inpatients with DSM-IV delirium, subsyndromal delirium, and no neurocognitive disorder and in different motor subtypes of patients with delirium.
Results
One hundred and ninety-eight patients (mean age 79.14 ± 8.26) were assessed with no delirium (n = 43), subsyndromal delirium (n = 45), and full syndromal delirium (n = 110). The ability to meaningfully engage with the tests varied from 59% for vigilance B test to 85% for Spatial Span forward test and was found to be least in the full syndromal delirium group. The no delirium group was distinguished from the delirium groups for all the tests and from the full syndromal delirium group for the vigilance B test and global visuospatial function test. The subsyndromal delirium group differed from the full syndromal delirium group in respect of global visuospatial function test, spatial span backwards and vigilance A tests. Patients with full syndromal delirium were best identified using the interlocking pentagons test and clock drawing test. The ability to engage with testing was higher for those in the no subtype group.
Conclusions
Simple bedside tests of attention, vigilance, and visuospatial ability are useful to help to distinguish neurocognitive disorders namely subsyndromal delirium from other presentations.

Increasingly, products are designed for global markets, yet studies of design practices primarily investigate designers from high-income countries. Specifically, the use of prototypes during design is likely affected by the background of the designer and the environment in which they are designing. To broaden our understanding of the extent to which prototyping best practices are used beyond Western designers, in this study, we conducted interviews with novice designers from Ghana, a middle-income country (MIC), to examine how Ghanaian novice designers (upper-level undergraduate students) used prototypes throughout their design courses. We compared the reported use of prototypes to best practice behaviors and analyzed the types of prototypes used. We found evidence that these Ghanaian novice designers used some critical prototyping best practice behaviors, while other behaviors were underutilized, specifically during the front-end phases of design and for the purpose of engaging with stakeholders. Additionally, virtual models dominated their prototyping choices. We discuss likely reasons for these trends based on participants’ design experiences and design contexts.
