Abstract Background Experimental and clinical findings suggest a crucial role of inflammation in epileptogenesis. We aimed to analyze levels of inflammatory cytokines in plasma and saliva from children with acute seizures and healthy controls and measure their associations with HHV6 and EBV infection. Methods We analyzed plasma from 36 children within 24 hours of acute seizures (cases) and 43 healthy controls and saliva from 44 cases and 44 controls with a multiplex immunoassay. Saliva from all controls and 65 cases and blood from 26 controls and 35 cases were also analyzed by ddPCR for viral DNA. Statistical analysis included Wilcoxon Rank Sum test, Fisher’s exact test, ANOVA and Spearman correlation. Results Compared to controls, children with breakthrough seizures (n=18) had higher levels of CCL11 (p<0.001), CCL26 (p<0.001), IL-8 (p=0.03), CCL4 (p=0.02) in plasma. Children with new onset seizures (n=13) showed higher levels of CCL11 (p=0.05) and IL-6 (p=0.01). Patients with febrile seizures (n=5) had higher levels of IFNγ (p<0.001), IL-6 (p<0.001), IL-10 (p<0.001), CXCL10 (p=0.001). CCL11 was higher with 3 or more seizures (p=0.01), seizures longer than 10 minutes (p=0.001) and when EEG showed focal slowing (p=0.02). In saliva, febrile seizures had higher levels of IL-1β (n=7, p=0.04) and new onset seizures had higher IL-6 (n=15, p=0.02). Plasma and saliva cytokine levels did not show correlation. Frequency of HHV-6 and EBV detection was similar across seizure types and not different than controls. We found no correlation between viral load and cytokine levels Conclusions We showed differential activation of neuroinflammatory pathways in plasma from different seizure etiologies compared to controls, unrelated to HHV-6 infection.

Background: Topical corticosteroid (TCS) abuse is rampant and results in steroid addiction labeled as topical steroid-dependent or damaged face (TSDF). Indian market is replete with triple combination creams containing TCS sold as over-the-counter products at low cost, luring people to use them without prescription. The resultant damage if detected late is irreversible and difficult to treat. Dermoscopy can help in the early identification of features of TSDF at a preclinical stage resulting in better prognosis. However, the literature on the same is limited. Aims: This study is undertaken to characterize dermoscopic features of TSDF and to correlate them with potency and duration of application of the TCS. Methods: One hundred and thirty-two patients aged 18 years or above, with clinical symptoms and signs suggestive of TSDF and with history of application of TCS on the face for a period of more than one month, were enrolled in the study. Their demographic details, clinical features, and dermoscopy findings were recorded using a predesigned structured format. Comparison of dermoscopic findings with clinical examination, gender, potency of TCS, and duration of TCS use was done using Chi-square test, Fisher’s exact test, and one-tailed Z-test. Results: Mean age of the patients was 31.7 ± 8.1 years. Male to female ratio was 2:9. Sixty-nine (52.3%) patients abused TCS for more than one year. Clinical findings noted in the patients were erythema (81.1%), hyperpigmentation (80.3%), and hypertrichosis (68.2%). The most common dermoscopy findings seen were brown globules (96.2%), red diffuse areas (92.4%), vessels (87.1%), white structureless areas (86.4%), and hypertrichosis (80.3%). Red diffuse areas, vessels, brown globules, white structureless areas, and white hair were observed in a statistically higher proportion of cases dermoscopically. Y-shaped vessels and brown globules were seen in significantly higher number of patients, using TCS for more than three months and in those continuing it beyond six months, polygonal vessels were predominant. Limitations: Lack of histopathological correlation is the limitation of our study. Furthermore, brown globules seen in 96.2% patients of TSDF on dermoscopy may have been over-estimated and not always signify TSDF; instead, it could represent melasma for which patient applied TCS. Conclusion: Dermoscopy in TSDF can help dermatologists in a multitude of ways from confirming the diagnosis to differentiating from other causes of red face and predicting the approximate duration of TCS abuse.

Abstract Background SARS-CoV-2 and HIV disproportionally affect underrepresented ethnoracial groups in the US. Medical mistrust and vaccine hesitancy will likely impact acceptability of SARS-CoV-2 vaccines. This study examined SARS-CoV-2 vaccine hesitancy among underrepresented ethnoracial groups with HIV and identified factors that may reduce vaccine uptake. Methods We conducted a cross-sectional study of adults ≥18 years with HIV residing in Miami, FL. Participants were invited to participate in the ACTION (A Comprehensive Translational Initiative on Novel Coronavirus) cohort study. A baseline survey was administered from April-August 2020 and followed by a COVID-19 vaccine hesitancy survey from August-November 2020. The COVID-19 vaccine hesitancy survey was adapted from the Strategic Advisory Group Experts survey. Comparisons by race and ethnicity were performed using the Freedman-Haltmann extension of Fisher’s exact test Results A total of 94 participants were enrolled, mean age 54.4 years, 52% female, 60% Black non-Latinx, and 40% non-Black Latinx. Black non-Latinx participants were less likely to agree that vaccinations are important for health when compared to non-Black Latinx (67.8% vs 92.1%, p=0.009), less likely to agree that vaccines are effective in preventing disease (67.8% vs 84.2%, p=0.029), less likely to believe that vaccine information is reliable and trustworthy (35.7% vs 71.1%, p=0.002), and less likely to believe vaccines were unnecessary because COVID-19 would disappear soon (11% vs 21%, p=0.049). Conclusion Medical mistrust, vaccine hesitancy and negative sentiments about SARS-CoV-2 vaccines are prevalent among underrepresented ethnoracial groups with HIV, particularly Black non-Latinx. Targeted strategies to increase vaccine uptake in this population are warranted.

Objective: Fever alone can lead to rare serious complications in children, such as febrile seizures. The aim of this study is to assess the knowledge, beliefs, and behavior of parents toward fever and its management. Methods: A cross-sectional study using an online questionnaire was applied over a period of 3 months, from January to March 2018, to parents who were living in Saudi Arabia. The inclusion criteria were a parent who is a resident of Saudi Arabia, with at least one child aged 6 years or less, while incomplete questionnaires, having a child aged more than 6 years, or parents who were not living in Saudi Arabia were excluded. Results: A total of 656 parents completed the questionnaire. More than two-thirds of the subjects were female, the majority of whom were aged between 25–33 years old. The best-reported place to measure the temperature of children was the armpit (46%), followed by the ear (28%) and the mouth (10.7%). More than half of the parents considered their children feverish at a temperature of 38 °C. The majority of parents (79.7%) reported that the most serious side effects of fever were seizure, brain damage (39.3%), coma (29.9%), dehydration (29.7%), and death (25%). The most common method used to measure a child’s temperature was an electronic thermometer (62.3%). The most common antipyretic was paracetamol (84.5%). Conclusions: Our study demonstrates the good knowledge of parents in identifying a feverish temperature using the recommended route and tools for measuring body temperature.

Abstract Background Hemodynamic changes have been observed in patients with Graves’ disease. The aim of our study was to evaluate choroidal vascular change using the choroidal vascularity index (CVI) in patients with thyroid-associated ophthalmopathy (TAO). Methods In this cross-sectional observational study, 40 patients affected by TAO were recruited. Forty healthy individuals, matched for age and sex, served as controls. Foveal enhanced-depth imaging optical coherence tomography scans were obtained from all participants. Images were binarized using the ImageJ software and luminal area (LA) and total choroidal area (TCA) were measured. CVI was calculated as the proportion of LA to TCA. The relation between CVI or subfoveal choroidal thickness (SFCT) and clinical activity score, exophthalmometric value, diplopia status, gender, and age was evaluated. Results CVI was significantly higher in patients with TAO (P = 0.004). No significant difference was observed in SFCT (P = 0.200) and TCA (P = 0.153) comparing TAO patients and healthy controls. LA was significantly higher in TAO group (P = 0.045). On multiple regression analysis, CVI was associated with TCA (P = 0.043). No association was found between SFCT or CVI and TCA, clinical activity score, exophthalmometric value, Inami value, diplopia status, gender or age (P > 0.05). Conclusions This is the first study that has demonstrated an increase in CVI in eyes with TAO compared with healthy controls and has assessed its association with clinical features.

The Impact

BackgroundThe public health response to the SARS-CoV-2 (COVID-19) pandemic has had a detrimental impact on employment and there are concerns the impact may be greatest among the most vulnerable. We examined the characteristics of those who experienced changes in employment status during the early months of the pandemic.MethodsData were collected from a cross-sectional, nationally representative household survey of the working age population (18–64 years) in Wales in May/June 2020 (n=1379). We looked at changes in employment and being placed on furlough since February 2020 across demographics, contract type, job skill level, health status and household factors. χ2 or Fisher’s exact test and multinomial logistic regression models examined associations between demographics, subgroups and employment outcomes.ResultsOf our respondents, 91.0% remained in the same job in May/June 2020 as they were in February 2020, 5.7% were now in a new job and 3.3% experienced unemployment. In addition, 24% of our respondents reported being placed on furlough. Non-permanent contract types, individuals who reported low mental well-being and household financial difficulties were all significant factors in experiencing unemployment. Being placed on ‘furlough’ was more likely in younger (18–29 years) and older (60–64 years) workers, those in lower skilled jobs and from households with less financial security.ConclusionA number of vulnerable population groups were observed to experience detrimental employment outcomes during the initial stage of the COVID-19 pandemic. Targeted support is needed to mitigate against both the direct impacts on employment, and indirect impacts on financial insecurity and health.

Abstract Objective About a third of patients with multiple sclerosis (MS) suffer from chronic and excruciating central neuropathic pain (CNP). The mechanism underlying CNP in MS is not clear, since previous studies are scarce and their results are inconsistent. Our aim was to determine whether CNP in MS is associated with impairment of the spinothalamic-thalamocortical pathways (STTCs) and/or increased excitability of the pain system. Design Cross sectional study Setting General hospital Subjects 47 MS patients with CNP, 42 MS patients without CNP, and 32 healthy controls. Methods Sensory testing included the measurement of temperature, pain, and touch thresholds and the thermal grill illusion (TGI) for evaluating STTCs function, and hyperpathia and allodynia as indicators of hyperexcitability. CNP was characterized using interviews and questionnaires. Results The CNP group had higher cold and warm thresholds (p &lt; 0.01), as well as higher TGI perception thresholds (p &lt; 0.05), especially in painful body regions compared to controls, whereas touch and pain thresholds values were normal. The CNP group also had a significantly greater prevalence of hyperpathia and allodynia. Regression analysis revealed that whereas presence of CNP was associated with a higher cold threshold, CNP intensity, and the number of painful body regions were associated with allodynia and hyperpathia, respectively. Conclusions CNP in MS is characterized by a specific impairment of STTC function; the innocuous thermal pathways, and by pain hyperexcitability. Whereas CNP presence is associated with STTC impairment, its severity and extent are associated with pain hyperexcitability. Interventions that reduce excitability level may therefore mitigate CNP severity.

Abstract Background General Practitioners (GPs) may be called upon to assess patients who have sustained a concussion despite limited information being available at this assessment. Information relating to how concussion is actually being assessed and managed in General Practice is scarce. This study aimed to identify characteristics of current Western Australian (WA) GP exposure to patients with concussion, factors associated with GPs’ knowledge of concussion, confidence of GPs in diagnosing and managing patients with concussion, typical referral practices and familiarity of GPs with guidelines. Methods In this cross-sectional study, GPs in WA were recruited via the RACGP WA newsletter and shareGP and the consented GPs completed an electronic survey. Associations were performed using Chi-squared tests or Fisher’s Exact test. Results Sixty-six GPs in WA responded to the survey (response rate = 1.7%). Demographics, usual practice, knowledge, confidence, identification of prolonged recovery as well as guideline and resource awareness of GPs who practised in regional and metropolitan areas were comparable (p > 0.05). Characteristics of GPs were similar between those who identified all symptoms of concussion and distractors correctly and those who did not (p > 0.05). However, 84% of the respondents who had never heard of concussion guidelines were less likely to answer all symptoms and distractors correctly (p = 0.039). Whilst 78% of the GPs who were confident in their diagnoses had heard of guidelines (p = 0.029), confidence in managing concussion was not significantly associated with GPs exposure to guidelines. It should be noted that none of the respondents correctly identified signs of concussion and excluded the distractors. Conclusions Knowledge surrounding concussion guidelines, diagnosis and management varied across GPs in WA. Promotion of available concussion guidelines may assist GPs who lack confidence in making a diagnosis. The lack of association between GPs exposure to guidelines and confidence managing concussion highlights that concussion management may be an area where GPs could benefit from additional education and support.

Abstract Background Low back pain (LBP) is one of the most common musculoskeletal disorders, causing significant personal and social burden. Current research is focused on the processes of the central nervous system (particularly the sensorimotor system) and body perception, with a view to developing new and more efficient ways to treat chronic low back pain (CLBP). Several clinical tests have been suggested that might have the ability to detect alterations in the sensorimotor system. These include back-photo assessment (BPA), two-point discrimination (TPD), and the movement control tests (MCT). The aim of this study was to determine whether the simple clinical tests of BPA, TPD or MCT are able to discriminate between nonspecific CLBP subjects with altered body perception and healthy controls. Methods A cross-sectional study was conducted. At one point in time, 30 subjects with CLBP and 30 healthy controls were investigated through using BPA, TPD and MCT on the lower back. Correlations among the main covariates and odds ratios for group differences were calculated. Results MCT showed an odds ratio for the presence of CLBP of 1.92, with a statistically significant p-value (0.049) and 95%CI. The TPD and BPA tests were unable to determine significant differences between the groups. Conclusions Of the three tests investigated, MCT was found to be the only suitable assessment to discriminate between nonspecific CLBP subjects and healthy controls. The MCT can be recommended as a simple clinical tool to detect alterations in the sensorimotor system of nonspecific CLBP subjects. This could facilitate the development of tailored management strategies for this challenging LBP subgroup. However, further research is necessary to elucidate the potential of all the tests to detect alterations in the sensorimotor system of CLBP subjects. Trial registration No trial registration was needed as the study contains no intervention. The study was approved by the Swiss Ethics Commission of Northwest and Central Switzerland (EKNZ) reference number 2015–243.

AbstractPatients with stress-induced exhaustion disorder (SED) demonstrate cognitive dysfunction similar to patients with minor traumatic brain injury (TBI). We have previously detected elevated concentrations of astrocyte-derived extracellular vesicles (EVs) in patients with TBI. As such, we hypothesized that astrocyte-derived EVs could be higher in patients with SED than in patients with major depressive disorder (MDD) and healthy controls. Patients with SED (n = 31), MDD (n = 31), and healthy matched controls (n = 61) were included. Astrocyte-derived EVs (previously known as microparticles) were measured in plasma with flow cytometry and labeled against glial fibrillary acidic protein (GFAP) and aquaporin 4 (AQP4). In addition, platelet EVs and their CD40 ligand expression were measured. Patients with SED had significantly higher concentrations of AQP4 and GFAP-positive EVs and EVs co-expressing AQP4/GFAP than patients with MDD and healthy controls. Patients with MDD had significantly higher concentrations of GFAP-positive EVs and EVs co-expressing AQP4/GFAP than healthy controls. Platelet EVs did not differ between groups. CD40 ligand expression was significantly higher in patients with SED and MDD than in controls. In conclusion, the present study suggests that patients with SED, and to some extent, patients with MDD, have increased leakage of astrocyte-derived EVs through the blood–brain barrier.
