Electroencephalogram Eeg

The COVID-19, which has rapidly spread and infected millions of people from all over the world, causes various problems including psychiatric, economic, educational as well as health. Many studies have been reported that COVID-19 can be characterized by vascular damage predominantly involving micro vessels. In this study, we proposed a method to examine whether COVID-19 effects on brain computer interface (BCI) performance or not. We collected P300 based electroencephalogram (EEG) signals from six subjects before and after the COVID-19 infection. For classifying the P300 and non-P300 EEG signals, single output and two-layer artificial neural network was utilized. Based on the t-test analysis, it was observed that there was a significant difference between the before and after COVID-19 infection test groups especially on Oz channel in occipital region for alpha=0.05 percent while that of for alpha=0.01 percent shows no statistical difference for P300 classification results. The latency values, on the other hand, before and after COVID-19 infection did not represent any difference for both significance levels. It is clearly understood from the literature that COVID-19 negatively effects to the microvascular bed. Therefore, it might be expected that it could cause to reduce the P300 based BCI performance. This was the first study to investigate the impact of COVID-19 on P300-based BCI performance, taking into account the EEG signals of the COVID-19 infection. The obtained results showed that although the COVID-19 infection did not generally effected P300 based BCI application performance and latency values, the performance of the occipital region electrodes slightly effected.

Abstract Background The incidence of Candida bloodstream infections has risen over the last several decades. Complications of candidemia include endogenous fungal endophthalmitis which can result in devastating outcomes including vision loss. In 2015, the IDSA guidelines were updated to recommend echinocandins as initial therapy for candidemia. Given the poor ocular penetration of echinocandins there has been some concern this change may portend an increased incidence of ocular complications in candidemic patients. We sought to examine whether patients who received empiric echinocandin therapy developed higher rates of ophthalmic complications of candidemia. Methods We identified patients in our healthcare system who had blood cultures positive for Candida species and a completed ophthalmology consult between January 1, 2014 and April 30, 2019. Chi-squared analysis was used to compare antifungal prescribing patterns before and after release of the updated IDSA guidelines. We assessed whether the switch to empiric echinocandin therapy as directed by the guidelines was associated with higher rates of abnormal eye exams. Results 47 patients treated before the guideline change were compared to 57 patients treated after the guideline change. There was no significant difference in age, gender, or comorbid diabetes and hypertension between the groups. Before the guideline change, 24/47 (51%) of patients received eye-penetrating antifungals. This decreased to 21/57 after the updated guideline (37%, p=0.21). The percentage of patients with positive eye exams was nearly equal before and after the updated guidelines, 10/47 (21%) before vs 13/57 (22%) after (p=1). After the guideline change, 7/21 (33%) of the patients treated with penetrating antifungals had positive eye exams vs 6/36 (16%) who received echinocandins (p=0.19). Conclusion Echinocandins are known to have poor ocular penetration yet our data demonstrate no change in the incidence of ophthalmic complications of candidemia after the 2016 guideline endorsed echinocandins as empiric therapy. The prevalence of positive eye exams throughout our study period was 22%, suggesting ongoing utility for these exams. Ongoing investigation is necessary to confirm and further study these findings.

More people working at offices are choosing to eat meals at their desks, making “desktop dining” an increasingly common phenomenon. Previous studies have reported that environmental distractors, such as television viewing, can influence meal intake and subsequent snack intake. However, the impact of stressful mental tasks on eating behavior has received relatively less attention, focusing only on subsequent meal intake or concurrent snack intake. This study sets out to determine whether eating while working influenced current meal energy intake. This research also examined the relationship between dietary restraint status and energy intake. A crossover experimental design was employed requiring participants (14 males and 29 females) to eat pizza quietly and at rest (control), and while working on a computer (work). Measurements included BMI, energy intake, state anxiety, restrained eating behavior, stress levels (pre- and post-eating), and appetite (before and after both work and control sessions). The findings showed that consuming food while working on a computer significantly increased stress but had no influence on energy intake compared to the control condition. However, post-eating hunger levels were significantly higher in the work condition compared to the control condition. As expected, satiety levels decreased significantly from pre- to post-eating for both work and control conditions. In addition, no significant relationship was observed between restrained eating behavior and energy intake in both work and control conditions. These results suggest that eating while working affected satiety of normal weight participants, as indicated by the significant difference in post-meal satiety levels between work and control conditions.

Background: On March 11, 2020, the World Health Organization (WHO) announced the Coronavirus outbreak officially as a pandemic. This pandemic has led to new measurements to prevent viral spread. The measures included decreasing the person’s mobility outside homes with subsequent changes in the lifestyles, particularly in physical activity and eating habits. It has been noticed that consumption of some vitamins may help in preventing or reducing the symptoms of viral infection. Those vitamins include vitamin C, D and zinc. There is a common observation that the general public believes that the use of vitamins, especially vitamins C, D and zinc, reduces the chance of acquiring COVID-19. Objectives: The aim of this study was to determine the impact of COVID-19 pandemic on taking vitamins supplements by the Saudi general population in order to explore their believes regarding the protective value of these vitamins against COVID-19 infection. Subjects and Methods: This cross-sectional study was conducted using a self-administrated questionnaire that was designed, uploaded to the Google form and distributed online to the general Saudi population through the social media (Whatsapp, Twitter) as well as through email between August and December 2020. Statistical Packaged of Social Sciences program (SPSS) for Windows (version 17.0., Chicago: SPSS Inc) was used to analyze the data. A significant difference was considered when the p value is < 0.05. Student t-test and Chi-square (χ2) test were used to compare the studied variables as appropriate. Results: A total of 1043 participants were included in this study (64.9% females, 35.1% males). The mean age for them was 35.3±14.78 years. Only 9.3% (97 participants) were diagnosed to have COVID-19. About 28% of the participants were in contact with COVID-19 cases. Among participants diagnosed to have COVID-19 infection, (13% versus 29%) were taking vitamin C and (2% versus 15%) were taking zinc supplements daily during the 6 months before and after the pandemic, respectively, while (20% versus 25%) were taking vitamin D supplements weekly during the 6 months before and after the pandemic, respectively. Among participants who were in contact with COVID-19 cases, (8% versus 20%) and (3% versus 11%) were taking vitamin C and zinc supplements daily during the 6 months before and after the pandemic, respectively, while (14% versus 16%) were taking vitamin D supplements weekly during the 6 months before and after the pandemic Conclusion: The interest of taking multivitamin by Saudi population, such as vitamins C and D, zinc increased during and after the pandemic compared to that before it. There is no scientific evidence based on previous studies confirmed the role of dietary supplementation and multivitamins in preventing COVID-19 infection, therefore, effective education on the rationale use of vitamins during COVID-19 pandemic should be emphasized at local and/or national levels.

Abstract Aims Despite being the most common surgical procedure, there is wide variation that exists in the management of simple subcutaneous abscesses with no national guideline describing best practice. During the COVID-19 Pandemic national guidelines promoted the use of regional or local anaesthetic (LA) instead of general anaesthesia (GA) to avoid aerosol generating intubation associated with GA. This study aimed to assess the impact of anaesthetic choice in outcomes following incision and drainage of subcutaneous abscesses. Methods Two cohorts of patients undergoing abscess incision and drainage at St. James’ University Hospital Leeds were retrospectively identified over a 14-week period before and after the introduction of the new COVID-19 anaesthetic guidelines. Wound healing surrogate endpoints were used: i) total number of follow up appointments and ii) attendance to healthcare services after 30 days from I&D. Result 133 patients were included. Significantly more procedures were performed under LA after the intervention (84.1% vs 5.7%; p &lt; 0.0001) with a significant reduction in wound packing (68.3% vs 87.1%. p=0.00473). Follow up data found no significant difference in the average number of follow-up appointments (7.46 vs 5.11; p = 0.0731) and the number of patients who required ongoing treatment after 30 days (n = 14 vs n = 14, p = 0.921). Conclusion Drainage of simple subcutaneous abscess under 5 cm is safe under local anaesthetic with no significant difference in surrogate endpoints of wound healing observed in this patient cohort. Recurrent packing may not be required. Future work should explore patient reported measures such as pain management and the health economics of this intervention.

These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose Hyperkalemia more commonly affects patients with a glomerular filtration rate of less than 60 mL/min. Using intravenous (IV) insulin to shift potassium intracellularly may cause hypoglycemia, requiring additional treatment or longer hospitalization. Literature on insulin dosing in this context is limited, with one previous study indicating that 5 units of IV insulin might be as effective and result in less hypoglycemia than the standard dose of 10 units of IV insulin. The hyperkalemia treatment pathway at our institution was revised in May 2018 to include a reduced-dose option (5 units of insulin) for patients with end-stage renal disease. This study aimed to compare the prevalence of hypoglycemia between patients who received standard-dose vs reduced-dose IV insulin. Methods This single-center, retrospective, quasi-experimental study evaluated the impact of revision of the hyperkalemia treatment pathway by assessing rates of hypoglycemia during the 6 months before and after implementation of the revised pathway. The primary endpoint was prevalence of hypoglycemia, defined as a blood glucose level of less than or equal to 70 mg/dL. Results There was no statistically significant difference in the occurrence of hypoglycemia when comparing the pre- and postimplementation groups (36 [17.7%] patients vs 34 [18.7%] patients; P = 0.7924). The postimplementation group had a statistically significant lower reduction in potassium levels after treatment than the preimplementation group (mean [interquartile range], –0.9 [–1.3, –0.5] mEq/L vs –0.6 [–1.2, –0.2] mEq/L; P = 0.0095). Baseline potassium levels were similar between the groups. Conclusion Administration of reduced-dose IV insulin for treatment of hyperkalemia was significantly less effective in lowering serum potassium levels and did not decrease prevalence of hypoglycemia. When accounting for potential confounders, the only variable that was associated with hypoglycemia was pretreatment glucose level.
