RESUMEN
Over 15,000 veterans in 135 VA nursing homes were systematically tested for SARS-CoV-2 and had daily temperatures assessed from March to August, 2020. Lower baseline temperatures, and in SARS-CoV-2+ , lower maximum temperatures were observed with advancing age. Clinicians should be aware of the potential diminished fever response in the elderly with SARS-CoV-2.

BACKGROUND: COVID-19 has had a severe impact on morbidity and mortality among nursing home (NH) residents. Earlier detection of SARS-CoV-2 may position us to better mitigate the risk of spread. Both asymptomatic and pre-symptomatic transmission are common in outbreaks, and threshold temperatures, such as 38C, for screening for infection could miss timely detection in the majority of residents. We hypothesized that in long-term care residents, temperature trends with SARS-CoV-2 infection could identify infection in pre-symptomatic individuals earlier than standard screening. METHODS: We conducted a retrospective cohort study using electronic health records in 6176 residents of the VA NHs who underwent SARS-CoV-2 testing triggered by symptoms. We collected information about age and other demographics, baseline temperature, and specific comorbidities. We created standardized definitions, and a hypothetical model to test measures of temperature variation and compare outcomes to the VA standard of care. RESULTS: We showed that a change from baseline of 0.4C identified 47% of NH residents who became SARS-CoV-2 positive, earlier than standard testing by an average of 42.2 h. Temperature variability of 0.5C over 3 days when paired with a 37.2C temperature cutoff identified 55% of NH residents who became SARS-CoV-2 positive earlier than the standard of care testing by an average of 44.4 h. A change from baseline temperature of 0.4C when combined with temperature variability of 0.7C over 3 days identified 52% of NH residents who became SARS-CoV-2 positive, earlier than standard testing by an average of 40 h, and by more than 3 days in 22% of the residents. This earlier detection comes at the expense of triggering 57,793 tests, as compared to the number of trigger tests ordered in the VA system of 40,691. CONCLUSIONS: Our model suggests that early temperature trends with SARS-CoV-2 infection may identify infection in pre-symptomatic long-term care residents.

BACKGROUND: Alzheimer's disease and related dementias (ADRD) impact the diagnosis and infection control of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in nursing homes (NH) by influencing the behavior of residents and their caregivers. Health system data show an association between ADRD and SARS-CoV-2. Whether this association is present in NH populations remains unknown. How increased SARS-CoV-2 risk among residents with ADRD impacts the greater NH population also remains unknown. METHODS: This retrospective cohort study used electronic health record data on Veterans residing in 133 Veterans Affairs Community Living Centers (CLC) and 15 spinal cord injury units from March 1, 2020 to December 13, 2020. We measured ADRD using diagnostic codes 12 months before an index SARS-CoV-2 test date for each resident. We used Poisson regression to determine the relative risk of SARS-CoV-2 for the highest quartile of facility ADRD prevalence versus the lowest, stratifying by individual ADRD status, and adjusting for covariates, with and without a random intercept to account for facility clustering. RESULTS: Across the study period, 15,043 residents resided in CLCs, 1952 (13.0%) had SARS-CoV-2, and 8067 (53.6%) had ADRD. There was an estimated 60% increased risk of SARS-CoV-2 in facilities with highest dementia prevalence versus lowest (relative risk, 1.6 [95% confidence interval 0.95, 2.7]). CONCLUSIONS: CLC residents had a greater likelihood of SARS-CoV-2 infection in facilities with greater ADRD prevalence. Facility characteristics other than ADRD prevalence may account for this association.

INTRODUCTION: Valproate is an antiepileptic medication that can be used to manage behavioral symptoms associated with Alzheimer's dementia. We present a rare case of valproate-induced periorbital edema. CASE: A 76-year-old man came to the emergency room with agitation and aggression. He was medically cleared and referred to a psychiatric facility where he was treated with haloperidol. When he developed drug-induced parkinsonism, the haloperidol was stopped, and the patient was started on valproate 250 mg twice daily. The day after valproate administration, the patient developed periorbital edema. After ruling out other causes of periorbital edema, adverse drug reaction was suspected. Valproate was discontinued, and the edema rapidly resolved within five days. CONCLUSION: Periorbital edema is a rare side effect of valproate. It can occur in patients who are being treated with valproate for behavioral changes in Alzheimer's disease. The edema resolves with discontinuation of the medication.

Coronavirus disease 2019 (COVID-19 - severe acute respiratory syndrome coronavirus 2 {SARS-CoV-2}) infection has been associated with thromboembolic events and coagulopathy, leading to a surge in the use of anticoagulants. The dose and duration of therapy differ according to the followed protocol. Several case reports documented fatal bleeding as an adverse effect of anticoagulation. We report a case of nearly fatal retroperitoneal bleed in an otherwise healthy 60-year-old man who developed severe COVID-19 requiring ICU stay and mechanical ventilation. The development of retroperitoneal bleed led to a 50% drop in his hemoglobin. The patient happens to be a Jehovah's Witness, and the family refused blood transfusion, which added to the complexity of the situation. Anticoagulation is associated with a potential risk of fatal bleed in critically ill COVID-19 patients. There are different protocols of anticoagulation in the management of SARS-CoV-2. The risk of bleeding vs thrombosis should be weighed on a case-by-case basis. A high degree of suspicion, early intervention, and knowledge of alternatives to blood transfusion can improve outcomes.
RESUMEN
Rhino-orbital Cerebral Mucormycosis (ROCM), a rare invasive fungal infection, affects diabetic and immunocompromised individuals. Recent reports have raised the alarm for invasive ROCM associated with SARS-CoV-2 infection. SARS-CoV-2 infection causes immune cell dysregulation, cytokine dysregulation, and is associated with invasive fungal infections. Immunosuppressive treatment of COVID-19 with corticosteroids increases the risk of opportunistic infection. We present a series of 3 cases of invasive ROCM with different outcomes in immunocompetent nondiabetic patients who all received corticosteroids at doses higher than those recommended by the World Health Organization, and who received oxygen during their SARS-CoV-2 treatment course. Immune dysregulatory effects of COVID-19 and high-dose corticosteroids may both have caused predisposition to ROCM in these cases. Additionally, health system stress caused by responding to COVID-19 surges may have predisposed patients to exposure to mucormycosis-causing fungi through use of non-sterilized water for oxygen humidification. In light of these cases, we encourage guideline-based corticosteroid dosing in the management of COVID-19 as well as vigilance for invasive mucormycosis and prompt treatment in corticosteroid-treated patients.

OBJECTIVES: COVID-19 has had a severe impact on morbidity and mortality among nursing home (NH) residents. Earlier detection of SARS-CoV-2 may position us to better mitigate risk of spread. Both asymptomatic or pre-symptomatic transmission are common in outbreaks, and threshold temperatures, such as 38C, for screening for infection could miss timely detection in the majority. DESIGN: Retrospective cohort study using electronic health records. METHODS: We hypothesized that in long-term care residents, temperature trends with SARS-CoV-2 infection could identify infection in pre-symptomatic and asymptomatic individuals earlier. We collected information about age and other demographics, baseline temperature, and specific comorbidities. We created standardized definitions, and an alternative hypothetical model to test measures of temperature variation and compare outcomes to the VA reality. SETTINGS AND PARTICIPANTS: Our subjects were 6,176 residents of the VA NHs who underwent SARS-CoV-2 trigger testing. RESULTS: We showed that a change from baseline of >0.4C identifies 47% of the SARS-CoV-2 positive NH residents early, and achieves earlier detection by 42.2 hours. Range improves early detection to 55% when paired with a 37.2C cutoff, and achieves earlier detection by 44.4 hours. Temperature elevation >0.4C from baseline, when combined with a 0.7C range, would detect 52% early, leading to earlier detection by more than 3 days in 22% of the residents. This earlier detection comes at the expense of triggering 57,793 tests, as compared to the number of trigger tests ordered in the VA system of 40,691. CONCLUSION AND IMPLICATIONS: Our model suggests that current clinical screening for SARS-CoV-2 in NHs can be substantially improved upon by triggering testing using a patient-derived baseline temperature with a 0.4C degree relative elevation or temperature variability of 0.7C trigger threshold for SARS-CoV2 testing. Such triggers could be automated in facilities that track temperatures in their electronic records.
RESUMEN
Being one of the widespread parasitic infections in particular parts of the United States, babesiosis may present with varying severity of clinical manifestations. Depending on the severity and degree of hemolysis, some patients may need a more aggressive approach, such as repeated red blood cell (RBC) transfusions, while in others, symptoms may be well-controlled with conservative therapy only using a disease-specific approach. We are presenting two cases with a significant difference in severity and medical therapy.
RESUMEN
INTRODUCTION: Toxic shock syndrome occurs from dysregulation of host inflammatory responses. Toxin- producing strains of Group A streptococcus cause TSS. Ischemic optic neuropathy rarely complicates septic shock. We present a rare case of streptococcal pharyngitis complicated by septic arthritis and TSS with reversible blindness due to non-arteritic ischemic optic neuropathy. CASE: A 28-year-old man drove to our ED with exudative pharyngitis. A rapid streptococcal test was positive. While awaiting oral penicillin he became hypotensive refractory to IV fluids and developed knee effusion. The patient noted progressive dimming of his vision. Arthrocentesis yielded GAS. ICU course was complicated by ARDS but after 2 weeks the patient was weaned off vasopressors and the ventilator. He regained his vision and had no neurological sequelae. The patient's GAS isolate was M protein gene (emm) type 1 and T type 1. He was followed in the IM clinic for 9 months post discharge with complete resolution of symptoms. CONCLUSION: The rapidity of the development of shock is attributed to streptococcal exotoxins acting as superantigens. GAS type M1 is commonly associated with severe shock in TSS. The severe shock was the likely cause of his ischemic optic neuropathy. Early recognition and aggressive management of TSS are crucial to clinical outcome.
