Using the world cafe method, four themed discussion tables explored (a) the breadth of scientific domains needed to meet the current challenges, (b) the nature and definition of the shifting concepts in nutrition sciences, (c) the next-generation methods required and (d) communication and organisational challenges and opportunities. As a follow-up to earlier work [1], here we report the highlights of the discussions, and propose the next steps to advance responsible research and innovation in the domain of nutritional science.PURPOSE Dietary pattern analysis has been considered as an approach to capture the complex interactions of overall diet, which are often lost in studies of single dietary components (e.g., foods and nutrients). The aim of this study was to identify the major dietary patterns of Koreans via principal component analysis based on the food groups and to investigate the association between dietary patterns and gastric cancer (GC) risk. METHODS In this study, participants were recruited from the National Cancer Center, Korea. Among them, 415 cases were diagnosed with early GC, and 830 controls were age- and sex-matched at a ratio of 12. To determine the subjects' dietary patterns, 34 predefined food groups based on the 106-item semiquantitative food frequency questionnaire (SQFFQ) were used. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated across the tertiles of dietary pattern scores using logistic regression models. RESULTS The two dietary patterns derived in this study were named westernized and prudent. Those patterns explained 24.83% of the total variation in food intake. Higher scores on the prudent pattern was inversely associated with the risk of GC (OR [95% CI] for the highest vs. lowest tertiles 0.58 [0.41-0.84], p for trend = 0.004). CONCLUSION Our findings suggest that adherence to the prudent dietary pattern represented by high loadings of vegetables and fruits, was associated with lower GC risk. Further studies with a prospective design and larger sample sizes are necessary.PURPOSE The study aimed to investigate the discrepancy and potential mechanisms of different CLA-producing B. breve on dextran sulphate sodium (DSS)-induced colitis. METHODS Colitis was induced in C57BL/6 J mice using DSS. Disease activity index (DAI), histopathological changes, epithelial barrier integrity and epithelial apoptosis were determined. Gut microbiota were gauged to evaluate the systemic effects of CLA-producing B. breve. RESULTS Oral administration of different B. breve showed different effects, in which B. breve M1 and B. breve M2 alleviated the inflammation induced by DSS as well as significantly increased the concentration of mucin2 (MUC2) and goblet cells, but neither B. breve M3 nor B. breve M4 had those protective effects. Meanwhile, B. breve M1 and B. breve M2 treatments significantly up-regulated the tight junction (TJ) proteins and ameliorated the epithelial apoptosis lead by DSS challenge. Moreover, inflammatory cytokines (TNF-α, IL-6) were modulated by B. breve M1 and B. breve M2, neither B. breve M3 nor B. breve M4. Furthermore, B. breve M1 and B. breve M2 reduced the abundance of Bacteroides and increased the abundance of Odoribacter, then rebalanced the damaged gut microbiota. Colonic CLA concentrations in mice fed with B. breve M1, B. breve M2, B. breve M3 and B. breve M4 decreased successively, which showed significant positive correlation with the effectiveness of relieving colitis. CONCLUSIONS Bifidobacterium breve M1 and B. breve M2 alleviated DSS-induced colitis by producing CLA, inhibiting the inflammatory cytokines, maintaining of the intestinal epithelial barrier and regulating the gut microbiota.PURPOSE To describe optical coherence tomography angiography (OCTA) and other multimodal imaging features of multiple evanescent white dot syndrome (MEWDS). METHODS The retinal and choriocapillary vascular density of MEWDS patients were measured by OCTA (OptoVue Inc.) in the acute and recovery phases. And other multimodal imaging data were also retrospectively reviewed. RESULTS Sixteen patients with a mean age of 26.5 ± 6.99 years were included. Three patients were complicated with choroidal neovascularization (CNV). The mean baseline logMAR BCVA of the affected eyes was 0.52 ± 0.36 (Snellen equivalent 20/50). OCTA revealed significant reductions in vascular densities of deep capillary plexus (45.72 ± 3.70%, P = 0.0007), and choriocapillaris (46.08 ± 3.22%, P  less then  0.0001) of the affected eyes compared with the contralateral eyes (50.23 ± 4.06% and 52.28 ± 4.19%, respectively) in the acute phase. During the recovery phases, vascular densities of deep capillary plexus (49.50 ± 3.15%, P  less then  0.0001) and choriocapillaris (53.67 ± 2.58%, P  less then  0.0001) increased significantly in the affected eyes while those of the superficial capillary plexus remained stable. SD-OCT revealed an increase of the subfoveal choroidal thickness and disruption of the outer retinal layer, including ellipsoid zone discontinuities and the accumulation of hyperreflective material, corresponding to the hypofluorescent spots and dots on ICGA, respectively. BCVA increased to normal values after recovery, together with restoration of the structural morphology and choroidal thickness on SD-OCT, except in eyes with CNV. CONCLUSION The inner retinal layer and choroid can be secondarily transiently compromised in MEWDS. MEWDS complicated with CNV is associated with worse visual outcomes.PURPOSE The study aimed to construct a new retinal tack design with high retention forces to prevent spontaneous disentanglement in cases of complicated retinal surgery. METHODS Six new forms for the peak of a retinal tack were developed using computer-aided design (CAD); then a prototype was produced for each model. Finally, standardised design testing was conducted using human (ex vivo) sclera by logging 15 consecutive measurements for each model. RESULTS Seven different models underwent pull-out testing (six new models and the original tack model), but two tack models (Model 4, Model 5) failed to penetrate the human tissue. The highest pull-out forces (median) were measured for Model 3, followed by Model 6, Model 2 and Model 1. The original Heimann tack (Model H) was found to have the lowest retention forces. CONCLUSION The different tack designs altered the penetration and holding forces. The retention forces of the proposed peak design led to a significant increase in the retention forces that were more than twice as high as those in the original Heimann Model.PURPOSE Potential sources of error in dosage planning in strabismus surgery are (a) prismatic side-effects of spectacle lenses when measuring the preoperative angle with the alternating prism cover test and (b) a potential influence of eye ball axial length on dose response. As both errors take effect in opposite directions, many strabismus surgeons set aside their consideration. This study investigates whether considering both factors for dosage planning yields better operative results. METHODS In this prospective, randomised, double-blind, interventional pilot study, we included patients scheduled for purely horizontal strabismus surgery and determined each patient's surgical dose (total amount of recession/plication) either with (study group) or without (control) consideration of the two factors. The deviation of the resulting angle from the target angle 3 months postoperatively was the primary endpoint. RESULTS One hundred one patients were included, 51 of which in the intervention group and 50 in the control group. check details The primary endpoint showed a median deviation from the target of 3.0° in the intervention group and 4.8° in the control group. We observed a group difference of 1.8° in favour of the intervention group (p = 0.053). Subgroup analysis showed a difference between groups of 2.2° for esotropic patients and of 5.1° for patients with hyperopia > + 2 D. CONCLUSION Taking prismatic side-effects of spectacle lenses and eye ball length into account when calculating strabismus surgery doses showed a trend towards more accurate results. Esotropic patients and patients with hyperopia > + 2 D seemed to benefit most. TRIAL REGISTRATION International Clinical Trials Registry Platform DRKS00011121.Galvanic vestibular stimulation (GVS) has increasingly been used to stimulate the vestibular system in health and disease. While perceptible supra-threshold GVS destabilizes postural control in healthy control (HC) subjects, imperceptible 'noisy' GVS (nGVS) is reported to improve postural control in patients with bilateral vestibulopathy (BV) and therapeutic devices using nGVS are currently under development. We questioned (1) whether perceptible GVS destabilizes postural control of BV patients, expecting any effect to be smaller than in healthy subjects due to the patients' vestibulopathy, and (2) whether imperceptible nGVS improves postural control in comparison to an active sham stimulus in context-dependent conditions, hypothesizing that it fades off once postural control becomes more challenging with respect to its sensory (standing on foam) or cognitive (dual task) complexity. We tested postural responses of 30 BV patients to bimastoidal perceptible (lowGVS, highGVS) or imperceptible (nGVS, sham, noGVS)bulo-perceptional and vestibulo-spinal thresholds should be taken into account. Finally, our data suggest that individual motion perception thresholds for GVS could potentially serve as a predictor of postural control safety and falling risk in BV.Neuroimaging underpinnings of state (in the moment, transient) mental fatigue in multiple sclerosis (MS) are not well understood. The current pilot study examined the effect of state mental fatigue on brain activation (measured using functional magnetic resonance imaging [fMRI]) during conditions of varying cognitive loads of rapid information processing in persons with MS relative to healthy controls. Nineteen persons with MS and 17 healthy controls underwent fMRI scanning while performing a modified version of the Symbol Digit Modalities Test, which consisted of high and low cognitive load conditions with comparable visual stimulation. State mental fatigue was assessed using the Visual Analog Scale of Fatigue before and after each run of the behavioral task. Results indicated that the healthy control group recruited significantly more anterior brain regions (superior and middle frontal gyri, insula, and superior temporal gyrus) to meet increased task demands during the high cognitive load condition as fatigue level increased (p  less then  0.05), which was accompanied by shorter response time. In contrast, the MS group did not recruit anterior areas to the same extent as the healthy control group as task demands and fatigue increased. Indeed, the MS group continued to activate more posterior brain regions (precuneus, lingual gyrus, and middle occipital gyrus) for the high cognitive load condition (p  less then  0.05) with no improvement in speed. In conclusion, persons with MS may allocate neural resources less efficiently than healthy controls when faced with increased task demands, which may result in increased mental fatigue. Results of the current pilot investigation warrant replication with a larger sample size.
