Adherence to a Mediterranean diet is associated with cognitive function in an older non- Mediterranean sample: findings from the Maine- Syracuse Longitudinal Study

Background: Adherence to a Mediterranean diet is associated with higher cognitive function and reduced risk of dementia in Mediterranean populations. However, few studies have investigated the association between Mediterranean diet adherence and cognition in populations outside of the Mediterranean basin. Furthermore, it is currently unknown whether the association between Mediterranean diet adherence and cognitive function differs between middle-aged and older individuals. Methods: Cross-sectional (n = 894) and longitudinal (n = 530) multivariable analyses were undertaken using data from community-dwelling adults from the Maine-Syracuse Longitudinal Study (MSLS). Mediterranean diet adherence was measured by applying a literature-based Mediterranean diet score to food frequency questionnaire data. Cognitive function was assessed with a battery of tests and composites scores were computed for global cognitive function, Visual-Spatial Organization and Memory, verbal memory, working memory, scanning, and tracking and abstract reasoning. Results: No cross-sectional associations between Mediterranean diet adherence and cognitive function were detected. Over a period of five years, higher adherence to a Mediterranean diet was associated with improvements in Global Cognitive Function, Visual-Spatial Organization and Memory and scanning and tracking in participants ≥70 years. No significant longitudinal associations were observed for participants \u3c70 years. Conclusion: Our findings suggest that higher adherence to a Mediterranean diet is associated with better cognitive performance, and therefore less cognitive decline, in older but not middle-aged individuals

Real-time flood inundation forecasting and mapping for key railway infrastructure: a UK case study

Flooding events that impede railway infrastructure can cause severe travel delays for the general public and large fines in delayed minutes for the rail industry. Early warnings of flood inundation can give more time to implement mitigation measures which help reduce cancellations, delays and fines. Initial work is reported on the development of a real-time flood inundation forecasting and mapping system for the Cowley Bridge track area near Exeter, UK. This location is on one of the main access routes to South West England and has suffered major floods in the past resulting in significant transport impacts. Flood forecasting systems in the UK mainly forecast river level/flow rather than extent and depth of flood inundation. Here, the development of a chain of coupled models is discussed that link rainfall to river flow, river level and flood extent for the rail track area relating to Cowley Bridge. Historical events are identified to test model performance in predicting inundation of railway infrastructure. The modelling system will operate alongside a series of in-situ sensors chosen to enhance the flood mapping forecasting system. Sensor data will support offline model calibration/verification and real-time data assimilation as well as monitoring flood conditions to inform track closure decisions

Adherence to a Mediterranean diet associated with lower blood pressure in a US sample: Findings from the Maine- Syracuse Longitudinal Study

Hypertension is a key modifiable risk factor for cardiovascular disease. The Mediterranean diet (MedDiet) may be associated with improvements in blood pressure. However, few studies have examined the association between MedDiet adherence and blood pressure in non-Mediterranean populations, and findings are mixed. We analyzed cross-sectional data (Wave 6) for 851 participants of the Maine-Syracuse Longitudinal Study. MedDiet adherence was calculated using food frequency questionnaire data and a literature-based MedDiet adherence score. Dependent variables included systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and mean arterial pressure (MAP). Separate linear robust regression analyses revealed significant associations between MedDiet adherence and for SBP (b = -0.69, 95% CI = [-1.25, -0.20]), DBP (b = -0.33, 95% CI = [-0.58, -0.04]), and MAP (b = -0.45, 95% CI = [-0.77, -0.11]), but not for PP. These findings indicate that the MedDiet is associated with some metrics of blood pressure in a large, community-based, non-Mediterranean sample

Origins Space Telescope: predictions for far-IR spectroscopic surveys

We illustrate the extraordinary potential of the (far-IR) Origins Survey Spectrometer (OSS) on board the Origins Space Telescope (OST) to address a variety of open issues on the co-evolution of galaxies and AGNs. We present predictions for blind surveys, each of 1000 h, with different mapped areas (a shallow survey covering an area of 10 deg$^{2}$ and a deep survey of 1 deg$^{2}$) and two different concepts of the OST/OSS: with a 5.9 m telescope (Concept 2, our reference configuration) and with a 9.1 m telescope (Concept 1, previous configuration). In 1000 h, surveys with the reference concept will detect from $\sim 1.9 \times 10^{6}$ to $\sim 8.7 \times 10^{6}$ lines from $\sim 4.8 \times 10^{5}$-$2.7 \times 10^{6}$ star-forming galaxies and from $\sim 1.4 \times 10^{4}$ to $\sim 3.8 \times 10^{4}$ lines from $\sim 1.3 \times 10^{4}$-$3.5 \times 10^{4}$ AGNs. The shallow survey will detect substantially more sources than the deep one; the advantage of the latter in pushing detections to lower luminosities/higher redshifts turns out to be quite limited. The OST/OSS will reach, in the same observing time, line fluxes more than one order of magnitude fainter than the SPICA/SMI and will cover a much broader redshift range. In particular it will detect tens of thousands of galaxies at $z \geq 5$, beyond the reach of that instrument. The polycyclic aromatic hydrocarbons lines are potentially bright enough to allow the detection of hundreds of thousands of star-forming galaxies up to $z \sim 8.5$, i.e. all the way through the re-ionization epoch. The proposed surveys will allow us to explore the galaxy-AGN co-evolution up to $z\sim 5.5-6$ with very good statistics. OST Concept 1 does not offer significant advantages for the scientific goals presented here.Comment: 24 pages, 20 figures, 2 tables, accepted for publication in PAS

Online Photography Toolkits: Digital Approaches to Practical Delivery.

This paper draws on pedagogical research, and in particular it focuses on a research project developed by the Photography team at the University of Northampton: Leet, S., Sherwood, T., Murphy, A., Kalpaxi, E., Franchi, E., Wardle, C., Lowe, C., Smith, J. A. (2016-2017) ‘Online Photography Toolkits: Digital Approaches to Practical Delivery’, funded by the Institute of Learning and Teaching (ILT) of the University of Northampton. The Photography team at the University of Northampton created a series of digital toolkits to enable students to access information ‘on demand’ through a number of platforms and mobile devices. The development of effective digital resources to facilitate independent asynchronous skills-oriented learning (that commonly involves a hands-on approach) has been acknowledged as an essential need and a challenge in previous Photography CAleRO workshops. The development of these resources also provides potential for greater openness, in terms of sharing resources among departments and the wider public, for educational, pedagogic, and marketing purposes. In line with the University’s Waterside move in 2018, the toolkits will provide a digital resource to aid blended and flipped learning within Photography undergraduate programmes – a way to provide access to essential technical information and support beyond the confines of conventional teaching environments. This project would be appropriate for first year students needing additional support, as well as second year and Top-Up students requiring a refresher of practical skills. Traditional teaching approaches can pose barriers to a number of students, and offer only a finite duration of contact through practical delivery. It is hoped that the implementation of online toolkits will promote inclusion and lead to improved engagement and achievement for all learners, including the significant number in our cohorts who have learning differences and physical disabilities (e.g. deafness)

A mediterranean diet to improve cardiovascular and cognitive health: Protocol for a randomised controlled intervention study

The Mediterranean diet has demonstrated efficacy for improving cardiovascular and cognitive health. However, a traditional Mediterranean diet delivers fewer serves of dairy and less dietary calcium than is currently recommended in Australia, which may limit long-term sustainability. The present study aims to evaluate whether a Mediterranean diet with adequate dairy and calcium can improve cardiovascular and cognitive function in an at-risk population, and thereby reduce risk of cardiovascular disease (CVD) and cognitive decline. A randomised, controlled, parallel, crossover design trial will compare a Mediterranean diet supplemented with dairy foods against a low-fat control diet. Forty participants with systolic blood pressure above 120 mmHg and at least two other risk factors of CVD will undertake each dietary intervention for eight weeks, with an eight-week washout period between interventions. Systolic blood pressure will be the primary measure of interest. Secondary outcomes will include measures of cardiometabolic health, dietary compliance, cognitive function, assessed using the Cambridge Neuropsychological Test Automated Battery (CANTAB), psychological well-being and dementia risk. This research will provide empirical evidence as to whether the Mediterranean diet can be modified to provide recommended dairy and calcium intakes while continuing to deliver positive effects for cardiovascular and cognitive health. The findings will hold relevance for the field of preventative healthcare and may contribute to revisions of national dietary guidelines

A Mediterranean diet with fresh, lean pork improves processing speed and mood: Cognitive findings from the MedPork randomised controlled trial

Background: The Mediterranean diet may be capable of improving cognitive function. However, the red meat restrictions of the diet could impact long-term adherence in Western populations. The current study therefore examined the cognitive effects of a Mediterranean diet with additional red meat. Methods: A 24-week parallel crossover design compared a Mediterranean diet with 2–3 weekly servings of fresh, lean pork (MedPork) and a low-fat (LF) control diet. Thirty-five participants aged between 45 and 80 years and at risk of cardiovascular disease followed each intervention for 8 weeks, separated by an 8-week washout period. Cognitive function was assessed using the Cambridge Neuropsychological Test Automated Battery. Psychological well-being was measured through the SF-36 Health Survey and mood was measured using the Profile of Mood States (POMS). Results: During the MedPork intervention, participants consumed an average of 3 weekly servings of fresh pork. Compared to LF, the MedPork intervention led to higher processing speed performance (p = 0.01) and emotional role functioning (p = 0.03). No other significant differences were observed between diets. Conclusion: Our findings indicate that a Mediterranean diet inclusive of fresh, lean pork can be adhered to by an older non-Mediterranean population while leading to positive cognitive outcomes

Including pork in the Mediterranean diet for an Australian population: Protocol for arandomised controlled trial assessing cardiovascular risk and cognitive function

Background. The Mediterranean diet is characterised by the high consumption of extra virgin olive oil, fruits, vegetables, grains, legumes and nuts; moderate consumption of fish, poultry, eggs and dairy; and low consumption of red meat and sweets. Cross sectional, longitudinal and intervention studies indicate that a Mediterranean diet may be effective for the prevention of cardiovascular disease and dementia. However, previous research suggests that an Australian population may find red meat restrictions difficult, which could affect long term sustainability of the diet. Methods. This paper outlines the protocol for a randomised controlled trial that will assess the cardiovascular and cognitive benefits of a Mediterranean diet modified to include 2-3 weekly serves of fresh, lean pork. A 24-week cross-over design trial will compare a modified Mediterranean diet with a low-fat control diet in at-risk men and women. Participants will follow each of the two diets for 8 weeks, with an 8-week washout period separating interventions. Home measured systolic blood pressure will be the primary outcome measure. Secondary outcomes will include body mass index, body composition, fasting blood lipids, C-reactive protein, fasting plasma glucose, fasting serum insulin, erythrocyte fatty acids, cognitive function, psychological health and well-being, and dementia risk. Discussion. To our knowledge this research is the first to investigate whether an alternate source of protein can be included in the Mediterranean diet to increase sustainability and feasibility for a non-Mediterranean population. Findings will be significant for the prevention of cardiovascular disease and age-related decline, and may inform individuals, clinicians and public health policy

A Systematic Review of Minor Phytocannabinoids with Promising Neuroprotective Potential

Embase and Pubmed were systematically searched for articles addressing the neuroprotective properties of phytocannabinoids, aside from cannabidiol and Δ9‐tetrahydrocannabinol, including Δ9‐tetrahydrocannabinolic acid (Δ9‐THCA), Δ9‐tetrahydrocannabivarin (Δ9‐THCV), cannabidiolic acid (CBDA), cannabidivarin (CBDV), cannabichromene (CBC), cannabichromenic acid (CBCA), cannabichromevarin (CBCV), cannabigerol (CBG), cannabigerolic acid (CBGA), cannabigerivarin (CBGV), cannabigerovarinic acid (CBGVA), cannabichromevarinic acid (CBCVA) cannabidivarinic acid (CBDVA) and cannabinol (CBN). Out of 2,341 studies, 31 articles met inclusion criteria. CBG (range 5 mg.kg‐1 to 20 mg.kg‐1) and CBDV (range 0.2 mg.kg‐1 to 400 mg.kg‐1) displayed efficacy in models of Huntington’s disease and epilepsy. CBC (10‐75 mg.kg‐1), Δ9‐THCA (20 mg.kg‐1) and Δ9‐THCV (range 0.025‐2.5 mg.kg‐1) showed promise in models of seizure and hypomobility, Huntington’s and Parkinson’s disease. Limited mechanistic data showed CBG, VCE.003, VCE.003.2 and Δ9‐THCA mediated some of their effects through PPARy, but no other receptors were probed. Further studies with these phytocannabinoids, and their combinations, are warranted across a range of neurodegenerative disorders

Establishing a Smartphone Ambulatory ECG Service for Patients Presenting to the Emergency Department with Pre-Syncope and Palpitations

Background and Objectives: The Investigation of Palpitations in the ED (IPED) study showed that a smartphone-based event recorder increased the number of patients in whom an electrocardiogram (ECG) was captured during symptoms over five-fold to more than 55% at 90 days compared to standard care and concluded that this safe, non-invasive and easy-to-use device should be considered part of on-going care to all patients presenting acutely with unexplained palpitations or pre-syncope. This study reports the process of establishing a smartphone palpitation and pre-syncope ambulatory care Clinic (SPACC) service. Materials and Methods: A clinical standard operating procedure (SOP) was devised, and funding was secured through a business case for the purchase of 40 AliveCor devices in the first instance. The clinic was launched on 22 July 2019. Results: Between 22 July 2019 and 31 October 2019, 68 patients seen in the emergency departments (EDs) with palpitations or pre-syncope were referred to SPACC. Of those, 30 were male and 38 were female, and the mean age was 45.8 years old (SD 15.1) with a range from 18 years old to 80 years old. A total of 50 (74%) patients underwent full investigation. On the first assessment, seven (10%) patients were deemed to have non-cardiac palpitations and were not fitted with the device. All patients who underwent full investigation achieved symptomatic rhythm correlation most with sinus rhythm, ventricular ectopics, or bigeminy. A symptomatic cardiac dysrhythmia was detected in six (8.8%) patients. Three patients had supraventricular tachycardia (4%), two had atrial fibrillation (3%), and one had atrial flutter (2%). Qualitative feedback from the SPACC team suggested several areas where improvement to the clinic could be made. Conclusion: We believe a smartphone palpitation service based on ambulatory care is simple to implement and is effective at detecting cardiac dysrhythmia in ED palpitation patients
