COVID-19 Is Changing Our Understanding of the Neuroscience of Viral Infections: What We Can Do to Prepare for the Future?
In the approximately two years since the emergence of COVID-19 (Coronavirus Disease 2019) myriad neurological symptoms have been reported that are seemingly unrelated to each other [...

A Case Report of Antibiotic-Induced Aseptic Meningitis in Psoriasis.
Although frequently prescribed, certain antibiotics such as trimethoprim-sulfamethoxazole carry the risk of a rare yet life-threatening adverse effect, termed drug-induced aseptic meningitis. Morbidity can be avoided if the medication is identified and discontinued. Patients in reported cases tend to be female and have an autoimmune disease or prior adverse reaction to the offending agent. As a rare and poorly characterized condition, the subset of patients using antibiotics at risk for aseptic meningitis remains unclear; hence, cataloging these adverse events remains critical for better elucidating the disease. Here, we report a 62-year-old man with psoriasis and no prior history of sulfa allergy, who presented with a sudden onset of fever, chills, vomiting, and muscle aches 5 hours after taking single doses of trimethoprim-sulfamethoxazole and ciprofloxacin. Common infectious causes were ruled out, and his medications were discontinued. Despite initial symptom resolution with discontinuation, the patient neurologically deteriorated over the next two days before eventually recovering with supportive care. This case highlights the variable presentation of drug-induced aseptic meningitis. In contrast to previous reports of drug-induced aseptic meningitis, our patient was male, older than the median age of 40 years, and did not have a prior adverse reaction to the antibiotic. Furthermore, to the best of our knowledge, we report a possible case of antibiotic-induced aseptic meningitis in a patient with psoriasis. Lastly, the case emphasizes not only the value of a thorough medication history but also the importance of recognizing that patients may deteriorate in the first 48 hours before resolution
Fast/Glycolytic Muscle Fiber Growth Reduces Fat Mass and Improves Metabolic Parameters in Obese Mice
SummaryIn contrast to the well-established role of oxidative muscle fibers in regulating whole-body metabolism, little is known about the function of fast/glycolytic muscle fibers in these processes. Here, we generated a skeletal muscle-specific, conditional transgenic mouse expressing a constitutively active form of Akt1. Transgene activation led to muscle hypertrophy due to the growth of type IIb muscle fibers, which was accompanied by an increase in strength. Akt1 transgene induction in diet-induced obese mice led to reductions in body weight and fat mass, resolution of hepatic steatosis, and improved metabolic parameters. Akt1-mediated skeletal muscle growth opposed the effects of a high-fat/high-sucrose diet on transcript expression patterns in the liver and increased hepatic fatty acid oxidation and ketone body production. Our findings indicate that an increase in fast/glycolytic muscle mass can result in the regression of obesity and metabolic improvement through its ability to alter fatty acid oxidation in remote tissues
Variables Associated with Coronavirus Disease 2019 Vaccine Hesitancy Amongst Patients with Neurological Disorders.
INTRODUCTION: Given that the success of vaccines against coronavirus disease 2019 (COVID-19) relies on herd immunity, identifying patients at risk for vaccine hesitancy is imperative-particularly for those at high risk for severe COVID-19 (i.e., minorities and patients with neurological disorders). METHODS: Among patients from a large neuroscience institute in Hawaii, vaccine hesitancy was investigated in relation to over 30 sociodemographic variables and medical comorbidities, via a telephone quality improvement survey conducted between 23 January 2021 and 13 February 2021. RESULTS: Vaccine willingness (n = 363) was 81.3%. Univariate analysis identified that the odds of vaccine acceptance reduced for patients who do not regard COVID-19 as a severe illness, are of younger age, have a lower Charlson Comorbidity Index, use illicit drugs, or carry Medicaid insurance. Multivariable logistic regression identified the best predictors of vaccine hesitancy to be: social media use to obtain COVID-19 information, concerns regarding vaccine safety, self-perception of a preexisting medical condition contraindicated with vaccination, not having received the annual influenza vaccine, having some high school education only, being a current smoker, and not having a prior cerebrovascular accident. Unique amongst males, a conservative political view strongly predicted vaccine hesitancy. Specifically for Asians, a higher body mass index, while for Native Hawaiians and other Pacific Islanders (NHPI), a positive depression screen, both reduced the odds of vaccine acceptance. CONCLUSION: Upon identifying the variables associated with vaccine hesitancy amongst patients with neurological disorders, our clinic is now able to efficiently provide ancillary COVID-19 education to sub-populations at risk for vaccine hesitancy. While our results may be limited to the sub-population of patients with neurological disorders, the findings nonetheless provide valuable insight to understanding vaccine hesitancy
