Diabetes emerged as major risk factor for severe acute respiratory syndrome (SARS) and adverse outcome in patients with the coronavirus disease 2019 (COVID-19). Nevertheless, the role of admission hyperglycemia in patients with COVID-19 has not been wellexplored, yet. With this retrospective analysis, we report for the first time that hyperglycemia on day-1 is the best predictor of radiographic imaging of SARS-CoV2, regardless of the past medical history of diabetes. Admission hyperglycemia should not be overlooked, but adequately treated to improve the outcomes of COVID-19 patients with our without diabetes.

Background: Diabetes is a major contributor to dementia in the elderly. Identifying mild cognitive decline in younger individuals with diabetes could aid in preventing the progression of the disease. The aim of our study is to compare whether patients with diabetes experience greater cognitive decline than those without diabetes. Methods: We conducted a cross-sectional study using population-based recruitment to identify a cohort of individuals with diabetes and corresponding control group without diabetes of 55-65 years of age. We defined diabetes according to the American Diabetes Association and conducted a battery of standardized neuropsychological tests consisting of nine verbal and nonverbal tasks assessing three cognitive domains. We defined cognitive decline as an abnormal test in one or more of the domains. We used hierarchical regression to predict abnormal cognitive function by diabetes status, adjusting for gender, education, hypertension, and depression. Results: We included 142 patients with diabetes and 167 control group patients. Those with diabetes had a mean age of 59-4 years, 54% were women, the mean education level was 11-4.5 years of schooling, and their hemoglobin A1c was 8.6-2.5. They had an overall lower mean of all five executive function measures, all seven attention measures, and all five memory measures (P < 0.05). In multivariate analyses, all executive function beta coefficients for diabetes were significant, whereas attention had four out of seven and memory had four out of five. Conclusions: Diabetes is associated with cognitive decline in younger patients with diabetes. Preventive strategies should be developed for the prevention of dementia in younger populations.

Traditional media were the most common method of recruitment, with radio interviews being the most frequently reported. Individually, none of them surpassed the frequency of people learning of the project from other people (snowball effect). Social networks play an important role, exceeding certain traditional media. We have described for the first time in Latin America the use of media as methods to recruit volunteers for research, and the importance of project dissemination by the participants to reach more people.

Balo concentric sclerosis is an infrequent variant of a demyelinating disease related to multiple sclerosis, initially thought to have an acute presentation and a fatal outcome. Recent studies have reported non-fatal forms of Balo concentric sclerosis, focusing on the importance of early diagnosis using magnetic resonance imaging (MRI), along with spectroscopy and diffusion/perfusion sequences. Recently, we have been able to draw a three-dimensional image of a specific bundle of fibers by means of a diffusion tensor technique of the magnetic resonance imaging tractography (t-MRI). We report the case of a young woman presenting with acute and progressive focal neurological symptoms, including right body paresis, whose diagnosis was suggested by MRI and confirmed by pathology to be Balo concentric sclerosis. She was treated with boluses of methylprednisolone, achieving full neurological remission one year after admission. This is, to our knowledge, the first report describing the use of t-MRI for diagnosing BCS. We consider that t-MRI will allow, in a near future, early diagnosis of the disease, its prompt treatment, and establishing new classification criteria. This case confirms the existence of benign forms of Balo concentric sclerosis with a good response to steroid therapy, where functional recovery is possible.

Introduction: Primary Adrenal insufficiency is an uncommon complication of antiphospholipid syndrome, with an incidence of 0.4% [2]. It is often secondary to bilateral adrenal hemorrhage. We present a case of bilateral adrenal hemorrhage in a patient with APLS on anticoagulation with rivaroxaban. Case: 46-year-old m with a history of antiphospholipid syndrome, recently transitioned from warfarin to rivaroxaban for anticoagulation, who presented to the ED after a syncopal episode following a prior episode of abdominal pain with an unremarkable work-up. He subsequently developed severe fatigue, dizziness, headaches, nausea and 15 lbs weight loss. On presentation, the patient was hypotensive(72/45 mmHg) and tachycardic. Intravenous hydration was started with minimal response. Initial laboratory testing showed serum sodium of 121mmol/L, potassium of 5.5mmol/L and random cortisol of 0.8mcg/dL. The patient was admitted to the intensive care unit where he was started on vasopressors and hydrocortisone 50 mg IV every 8 hours. A non-contrast CT of the abdomen and pelvis showed thickening of the adrenal glands with decreased attenuation. MRI of the abdomen showed hyper-intensity of the adrenal glands bilaterally (T1 images), without post-contrast enhancement suggestive of bilateral adrenal hemorrhage. His electrolytes normalized, and he was successfully discharged home on hydrocortisone and fludrocortisone replacement with outpatient follow-up. Discussion: Atraumatic bilateral adrenal hemorrhage is rare, but remains one of the most common endocrine-related complications of antiphospholipid syndrome (APLS). The venous anatomical configuration of the adrenal gland increases risk of thrombotic hemorrhagic infarction[1]. Patients with APLS are commonly anticoagulated to prevent thrombosis. The ideal anticoagulation regimen remains controversial. Only three other cases of spontaneous bilateral adrenal hemorrhage on patients with APLS using new oral anticoagulants (NOACs) were reported. The use of NOACs seem to increase the already-elevated risk of adrenal hemorrhage seen in patients with APLS. References: 1. Aldaajani, H. et al.
