Relating Photophobia, Visual Aura, and Visual Triggers of Headache and Migraine
Authors: Hayne Daniel P. , Martin Paul R. 
Published: February 2019

ObjectiveThis study investigated a potential association between visual factors and symptoms related to migraine. It was predicted that photophobia and visual aura would be positively associated with interictal light sensitivity and visual headache triggers (flicker, glare, and eyestrain), and that these 2 visual symptoms would also be associated.BackgroundPrevious studies have found independent neurophysiological associations between several visual factors and symptoms related to headache disorders. Many of these connections appear to be associated with increased cortical hypersensitivity, a phenomenon that might be in part due to repeated avoidance and reduced tolerance to triggers. If true, and if associations between visual factors and symptoms can be established, this may have implications for an exposure‐based treatment for migraine symptoms.MethodsFour hundred and ninety‐one participants (411 female, 80 male) were recruited through Griffith University (AUS), Headache Australia, Pain Australia, and through social media. Participants were grouped based on the presence of headache disorder symptoms and the presence or absence of photophobia and/or visual aura. A cross‐sectional online survey design was utilized to gather information pertaining to interictal light sensitivity, visual triggers, and visual symptoms.ResultsWith respect to interictal light sensitivity and photophobia, a significant difference (P < .001, eta squared [η2] = 0.084) was found between the 3 groups, where headache disorder participants with photophobia (group A1; mean [M] = 2.5, standard deviation [SD] = 0.97) reported significantly greater light sensitivity than participants with headache disorder and no photophobia (A2; M = 1.68, SD = 0.62) and control group participants (A3; M = 1.82, SD = 0.85). This pattern was repeated for participants reporting flicker as a headache trigger (P < .001, η2 = 0.061), with group A1 (M = 2.45, SD = 1.24) significantly higher than groups A2 (M = 1.68, SD = 0.83) and A3 (M = 1.68, SD = 0.89), and was also seen for glare as a headache trigger (P < .001, η2 = 0.092), with group A1 (M = 2.92, SD = 0.96) significantly higher than A2 (M = 2.31, SD = 0.89) and A3 (M = 2.09, SD = 0.93). This pattern of results was not replicated for headache disorder participants with and without visual aura. A significant association (P < .001) was found between photophobia and visual aura in headache disorder participants based on a chi‐square test of independence, with 86/136 participants reporting either both or neither visual symptom.ConclusionsThis study supports a link between certain visual phenomena in headache disorder populations, and supports future research into exposure‐based treatments for migraine symptoms.

AbstractObjectiveThis paper aims to explore the determinants of the online health information seeking (OHIS) and usage (OHIU) behaviours of consumers based on the perceived benefits and costs of such activities.MethodsThis study applies questionnaires and empirical research methods. A questionnaire is designed according to the hypothesis model. A total of 282 questionnaires are obtained from patients and their accompanying families in two large hospitals, and the SPSS 17.0 and AMOS 17.0 (IBM, Almond, NY, USA) software are used to analyse the sample data and to test the research models.ResultsThree key findings are obtained from the analysis. Firstly, functional, learning, social and personal integrative benefits positively affect the OHIS intent of consumers. Secondly, cognitive costs negatively influence the OHIU behaviour of consumers. Thirdly, personal integrative benefits and OHIS behaviour significantly influence the OHIU behaviour of consumers.ConclusionThis paper highlights the differences between OHIS and OHIU based on their impact factors and applies social exchange theory to understand such factors. Online health information providers must improve the ease of use of their websites or applications, enhance the quality of their health information and focus on their functionality.

AbstractBackgroundEvidence synthesis reviews in health care rely on the efficient identification of research evidence, particularly evidence from randomised controlled trials (RCTs). There are no recently validated filters to identify RCTs in the Cumulative Index to Nursing and Allied Health Literature (CINAHL Plus).ObjectivesTo develop, test and validate a search filter to identify reports of RCTs from CINAHL Plus.MethodsNine sets of relevant and irrelevant records were identified to develop and test search filters iteratively. Two sets were used to validate the sensitivity and precision of the filters. The performance of two previously published filters and the filter built into EBSCOhost was evaluated.ResultsWe present a validated filter which offers sensitivity of 0.88 (95% CI: 0.77–0.95) and precision of 0.36 (95% CI: 0.31–0.41). This is comparable to the sensitivity of published filters, but has much better precision.ConclusionsA sensitive and precise filter, developed using records selected based on title and abstract information, is available for identifying reports of RCTs in the CINAHL Plus database via EBSCOhost. Using this filter is likely to reduce the number of results needing to be screened to a quarter of those retrieved by other published filters.

AbstractThe QM gene that encodes for the ribosomal protein L10 was firstly identified from human tumour cells as a tumour suppressor. In this study, a QM gene was identified in silkworm Bombyx mori (BmQM) and its immunomodulatory function was explored. BmQM messenger RNA (mRNA) and protein were highly expressed in the silk gland and fat body, and expressed in all stages of silkworm growth. After challenged with four different microorganisms, the expression levels of BmQM mRNA in fat body or haemocytes were significantly upregulated compared with the control. After knock‐down of BmQM gene, the expressions of some immune genes (PGRPS6, Gloverin0, Lysozyme and Moricin) were affected, and the transcripts of prophenoloxidase1 and prophenoloxidase2 have different degrees of change. The phenoloxidase activity was significantly reduced when the purified recombinant BmQM protein was injected. Recombinant BmQM protein inhibited systemic melanization and suppressed prophenoloxidase activation stimulated by Micrococcus luteus, but it did not affect phenoloxidase activity. Far‐western blotting assays showed that the BmQM protein interacted with silkworm BmJun protein, which negatively regulates AP‐1 expression. Our results indicated that BmQM protein could affect some immune gene expression and negatively regulate the prophenoloxidase‐activating system, and it may play an important role in regulation of the innate immunity in insects.

AbstractColour patterns in butterflies and moths are crucial traits for adaptation. Previous investigations have highlighted genes responsible for pigmentation (ie yellow and ebony). However, the mechanisms by which these genes are regulated in lepidopteran insects remain poorly understood. To elucidate this, molecular studies involving dipterans have largely analysed the cis‐regulatory regions of pigmentation genes and have revealed cis‐regulatory modularity. Here, we used well‐developed transgenic techniques in Bombyx mori and demonstrated that cis‐regulatory modularity controls tissue‐specific expression of the yellow gene. We first identified which body parts are regulated by the yellow gene via black pigmentation. We then isolated three discrete regulatory elements driving tissue‐specific gene expression in three regions of B. mori larvae. Finally, we found that there is no apparent sequence conservation of cis‐regulatory regions between B. mori and Drosophila melanogaster, and no expression driven by the regulatory regions of one species when introduced into the other species. Therefore, the trans‐regulatory landscapes of the yellow gene differ significantly between the two taxa. The results of this study confirm that lepidopteran species use cis‐regulatory modules to control gene expression related to pigmentation, and represent a powerful cadre of transgenic tools for studying evolutionary developmental mechanisms.

AbstractThe hydrothermal corrosion behavior of SiC layer in tristructural‐isotropic (TRISO) fuel particles and its effect on the fracture strength were investigated. The corrosion test was performed using the static autoclave at 400°C/10.3 MPa. The SiC layer exhibited a thickness loss and the corrosion rate followed a linear law. During corrosion, carbon was formed on the SiC surface due to the loss of Si. The corrosion was found preferentially occurred at the grain boundary of SiC, leading to the grain detachment and pit formation. The rate determining step of the corrosion was SiO2 formation rather than SiO2 dissolution in the hydrothermal environment. The fracture strength of SiC shell after corrosion was evaluated using the crush test. It showed a slight decrease with an increase in corrosion time, due to the thickness reduction in SiC layer. The results of this study demonstrated that the SiC in TRISO particles has good corrosion resistance in the hydrothermal environment.

AbstractIn this study, the (Ca0.95M0.05)V2O6 (M = Zn, Ba) and the CaV2O6 ceramics were synthesized through a solid‐state reaction method, and the effects of Zn2+ and Ba2+ substitution on the structure, sintering temperature, densification, microstructure and microwave dielectric properties of CaV2O6 ceramic were analysed. The XRD patterns of the sintered samples indicated a single‐phase of CaV2O6 in all temperatures. Substitution of Zn2+ caused a lower sintering temperature and improved the densification of the CaV2O6 ceramic. While the dielectric properties of the (Ca0.95Ba0.05)V2O6 compound were not desirable, the (Ca0.95Zn0.05)V2O6 sample sintered at 650°C for 4 hours showed significant dielectric properties, with εr = 10.29, Q × f ~ 53 000 GHz (at 15.5 GHz) and τf = −72.37 ppm/°C. Moreover, the chemical compatibility of the CaV2O6 ceramic with Al electrode was examined.

Acupuncture may be beneficial for patients with mild hypertension, but the evidence is not convincing. We aimed to examine the effect of acupuncture on blood pressure (BP) reduction in patients with mild hypertension. We conducted a multicenter, single‐blind, sham‐controlled, randomized trial in eleven hospitals in China. The trial included 428 patients with systolic blood pressure (SBP) from 140 to 159 mm Hg and/or with diastolic blood pressure (DBP) from 90 to 99 mm Hg. The patients were randomly assigned to receive 18 sessions of affected meridian acupuncture (n = 107) or non‐affected meridian acupuncture (n = 107) or sham acupuncture (n = 107) during 6 weeks, or to stay in a waiting‐list control (n = 107). All patients received 24‐hour ambulatory blood pressure monitoring at weeks 6, 9, and 12. We included 415 participants in the intention‐to‐treat analysis. The two acupuncture groups were pooled in the analysis, since they had no difference in all outcomes. SBP decreased at week 6 in acupuncture group vs sham acupuncture vs waiting‐list group (7.2 ± 11.0 mm Hg vs 4.1 ± 11.5 mm Hg vs 4.1 ± 13.2 mm Hg); acupuncture was not superior to sham acupuncture (mean difference 2.7 mm Hg, 95% CI 0.4 to 5.9, adjusted P = 0.103) or waiting‐list control (2.9 mm Hg, 95% CI −0.2 to 6.0, adjusted P = 0.078). However, acupuncture was superior to sham acupuncture (3.3 mm Hg, 95% CI 0.2 to 6.3, adjusted P = 0.035) and waiting‐list control (4.8 mm Hg, 95% CI 1.8 to 7.8, P < 0.001) at week 9. Acupuncture had a small effect size on the reduction of BP in patients with mild hypertension.

AbstractWith the expansive use of immune checkpoint inhibitors, the frequency of immune‐related adverse events, including autoimmune type 1 diabetes, has been exponentially increased. The anti‐programmed death‐ligand 1 antibody, avelumab, has recently been approved for metastatic Merkel cell carcinoma therapy. Here, we report a patient that developed fulminant type 1 diabetes during avelumab treatment. An 81‐year‐old woman with no history of diabetes received avelumab for metastatic Merkel cell carcinoma. Elevated plasma glucose level (483 mg/dL), hemoglobin A1c level (7.5%) and ketosis were observed after 10 courses of avelumab without any symptoms related to hyperglycemia. As the laboratory tests showed insulin depletion, we diagnosed her with fulminant type 1 diabetes induced by avelumab. This is the first reported case of avelumab‐induced type 1 diabetes, illustrating the necessity for close monitoring of glycemic control during avelumab therapy, as well as other immune checkpoint inhibitors.

AbstractPurposeTo study the effects of altering condylar settings and pin openings on the trueness and precision of virtual articulators vs. mechanical articulators.Materials and MethodsMaxillary and mandibular typodonts with fiducial markers were mounted on a mechanical Artex‐CR articulator, and the mandibular teeth were prepared to allow guidance solely by the posterior determinants of the articulator and the incisal table. The relationship of the mounted typodonts was preserved digitally by scanning using manufacturer transfer plate adaptors. On the mechanical articulator, pattern resin was allowed to set between the maxillary and mandibular occlusal surfaces (area #25‐30) at the endpoints of dynamic movements at 3 condylar inclinations (SCI): 10°, 30°, and 45°, n = 12/inclination, or at 3 incisal pin openings (2, 5, and 10 mm, n = 12/opening). All other articulator settings were kept constant. Resin specimens attached to the typodonts were scanned within 5 minutes of setting, then removed, and the articulated typodonts rescanned. Fixed dental prostheses (FDPs) #25‐30 were designed on the virtual articulator using identical parameters to the mechanical articulator. Dynamic virtual movements were used to sculpt the design, and a file of the design was saved. The files of both types of samples were aligned and overlaid. Interocclusal separation was measured in triplicate at the indentation created by the mesiolabioincisal point angle on the incisal edge of #8 and the mesiobucco‐occlusal point angle of #3. Trueness and precision of both types of articulators were calculated and compared using one‐way ANOVA, followed by the Tukey HSD test (α = 0.05).ResultsThere was no statistically significant difference at altered pin openings in either trueness (F = 0.202, p = 0.37) or precision (F = 3.134, p = 0.09) for the majority of measurements. The only significant difference was in the precision between the 2 types of articulators at 5 mm incisal opening, and only at the anterior measurement point (F = 15.134, p = 0.0008); however, these differences were less than 100 μm. When the SCI was altered, there was no statistically significant difference (F = 3.624, p > 0.05) between the virtual and mechanical articulators in trueness for 5 of the 6 measurements obtained (F = 3.624, p = 0.07) or for all of the precision measurements (F = 3.529, p = 0.07). The one trueness measurement that was significantly different (F = 9.237, p = 0.006) occured at SCI of 10°, and it was less than 100 µm.ConclusionsDynamic movements on the virtual articulator were shown to be as true and precise as to the mechanical articulator. When there were deviations, these deviations were less than 100 µm and thus, these deviations may not be clinically relevant.

AbstractQuestions(a) Are there differences in abundance‐weighted functional trait values between native and alien species in coastal plant communities? (b) Which functional traits are associated with a higher level of invasion in these communities? (c) Do functional diversity patterns differ between native and alien species? (d) Is alien species occurrence linked to small‐scale functional homogenization effects on the resident native species?LocationN‐Adriatic coastal ecosystems (Marano and Grado lagoon, Friuli Venezia Giulia region, Italy).MethodsWe sampled coastal vegetation within two habitats (foredunes and saltmarshes) along nine belt transects in two sampling sites. Plant species richness and abundance were assessed in 128 plots along with a suite of plant functional traits. We tested for differences in community‐weighted means between native and alien species within the two habitats, and Linear Mixed Models provided insights into traits fostering the invasion success among alien species. To check for potential functional homogenization driven by alien species invasion, we explored functional diversity patterns of native and alien species (β and γ functional diversity) and the relationship between α functional diversity and alien cover.ResultsAlien species had lower functional diversity than natives and were characterized by lower leaf construction costs coupled with lower drought resistance and higher water transport efficiency. The most abundant aliens were the ones minimizing carbon investment for leaf construction. In addition, we also found evidence for small‐scale functional homogenization driven by alien invasion.ConclusionsOur results suggested that native species adopt a resource conservative strategy whereas alien species are characterized by a higher resource acquisition capacity (i.e., acquisitive strategy). Our data also confirmed that alien species are less functionally diverse than natives, potentially driving the community towards small‐scale functional homogenization, resulting in a loss of species and a reduction in the functional space.

Structured AbstractObjectivesTo assess in vivo colour alterations of teeth following removal of fixed orthodontic appliances during retention.Setting and Sample PopulationThe Department of Orthodontics at the Aristotle University of Thessaloniki. Forty‐eight patients after orthodontic treatment.Material and MethodsDebonding and cleaning procedures after orthodontic treatment were performed using two different carbide burs attached to a low or high‐speed handpiece, respectively, in a non‐blinded cohort study with split‐mouth design. Spectrophotometric colour data of teeth were recorded: (a) after debonding, (b) three months later, prior to and following finishing with Soflex discs, and (c) after 1 year. The CIE Lab colour parameters were measured for each tooth, and the corresponding ΔΕ differences were calculated. The effect on colour was assessed with 3‐way mixed ANOVA and Bonferroni's comparisons test (a < 0.05).ResultsOrthodontic debonding and cleaning procedures were found to have statistically significant effects on the CIE colour parameters of treated teeth, since the L* values decreased 0.6 units (P < 0.001), a* values were stable (0.0 units) and b* values increased 1.4 units (P < 0.001), during the first retention year. Finishing temporarily decreased the enamel colour differences. Total ΔΕ differences for all types of teeth measured ranged from 1.4 to 2.1 units. The greatest changes were exhibited during the first 3 months in teeth on which high‐speed rotary instruments were used (1.6 units).ConclusionThe clinical relevance of this study points out that the colour of natural teeth following removal of fixed orthodontic appliances changes in long‐term.

AbstractObjectivesOral lichen planus (OLP) is a chronic inflammatory condition with an unclear pathological mechanism. IκB kinase α (IKKα)‐regulated mammary serine protease inhibitor (MASPIN) has been shown to mediate inflammation, particularly in cancers. Here, we explored the expression of MASPIN in OLP and its role in the inflammatory response.Materials and MethodsImmunohistochemistry staining and reverse transcription‐polymerase chain reaction assays were used to detect the subcellular localization and expression of MASPIN and IKKα in OLP and healthy control tissues. Levels of the inflammatory factors were compared with enzyme‐linked immunosorbent assays. MASPIN and IKKα were overexpressed and silenced, respectively, in an inflammation model of human oral keratinocytes (HOKs) stimulated with lipopolysaccharide (LPS).ResultsMammary serine protease inhibitor expression was down‐regulated, whereas IKKα expression was up‐regulated in OLP tissues (p < 0.01). The levels of tumour necrosis factor‐alpha and interleukin‐6 in OLP tissues were increased compared to those of healthy controls (p < 0.01). MASPIN overexpression in LPS‐stimulated HOK cells inhibited the levels of IKKα and the secretion of inflammatory cytokines. By contrast, IKKα silencing promoted the expression of MASPIN and inhibited the secretion of inflammatory cytokines.ConclusionBoth MASPIN and IKKα are involved in the inflammatory process of OLP, suggesting potential therapeutic targets.
