    Abstract While the cause of altered mentation in the elderly may be multifactorial, infectious etiologies may be missed. This case report aims to detail an account of a patient with dementia, found to have Lyme meningitis in the setting of a normal pressure hydrocephalus (NPH). The patient smelled of urine and presented with ambulatory dysfunction, fitting the "wet, wacky, and wobbly" triad of NPH while also having subjective chills and leukocytosis. Non-contrast brain CT scan showed dilated ventricles. Cerebrospinal fluid (CSF) studies suggested aseptic meningitis. Serum studies using a modified two-tiered algorithm confirmed the diagnosis of Lyme disease. Treatment of the underlying condition with a prolonged course of doxycycline improved symptoms and clinical course. Review of the literature on the association between Lyme meningitis and NPH reveals that few cases of Lyme-related NPH have been reported worldwide and further research into the pathophysiology, diagnostic approach, treatment modalities, and management of NPH secondary to Lyme meningitis may be warranted.

    Abstract Objective: Despite advancement in vaccines and treatments for COVID-19 over the past 2 years, many concerns remain about reinfection and waning immunity against COVID-19 and its variants, especially among people with substance use disorder (SUD). The study assessed the risk of COVID-19 reinfection and severe illness among adults with SUD and their vaccination status to inform management in this vulnerable population as the pandemic continues.
    Design: Retrospective cohort study.
    Setting: Nationwide electronic health records (TriNetX database) in the USA among adults with COVID-19 infection from January 2020 to June 2022.
    Participants: Adults (age ≥18 years) who were infected by COVID-19, excluding those who had cancer or lived in nursing homes or palliative care facilities.
    Outcome measures: COVID-19 reinfection was defined as a new diagnosis after 45 days of the initial infection. Logistic regression was applied to assess the OR of COVID-19 reinfection and severe outcomes within 30 day of reinfection for adults with alcohol (AUD), opioid (OUD), cocaine (CUD), stimulant (STUD), cannabis (CAUD) and other use disorders, controlled for demographic and comorbid conditions.
    Results: The SUD cohort was 13%-29% more likely to be reinfected by COVID-19 and had significantly higher 30-day mortality. Adults with AUD, STUD and OUD were at greater risks (adjusted ORs, AORs=1.69-1.86) of emergency department, hospital and intensive care admissions after 30 days of reinfection. Individuals with SUD and multiple vaccines doses were associated with decreased risks of worse COVID-19 outcomes. Lower COVID-19 reinfection rates (AORs=0.67-0.84) were only found among individuals with AUD, CUD or CAUD who had COVID-19 vaccination.
    Conclusions: Individuals with SUD had greater risks of COVID-19 reinfection and poor outcomes, especially those with OUD, STUD and AUD. Multiple vaccinations are recommended to reduce severe illness after COVID-19 reinfection in the SUD population.

    Abstract Inaccurate perceptions of COVID-19 (coronavirus disease 2019) risk may decrease compliance with public health mitigation practices, in turn increasing disease burden. The extent to which public perceptions of COVID-19 risk are inaccurate is not well studied. This study investigates the relationship between preferred information sources and inaccurate COVID-19 risk perception. A cross-sectional online survey of adults in the United States using online snowball techniques was administered between April 9, 2020 and July 12, 2020. Raking techniques were used to generate a representative U.S. sample from 10,650 respondents. Respondents who did not provide an answer to key questions were excluded. The remaining sample included 1,785 health care workers (HCW) and 4,843 non-HCW. Subjective risk was measured as the product of perceived likelihood of COVID-19 infection and perceived harm from infection. Objective risk was measured as a function of the presence of known COVID-19 risk factors. Discrepancies between subjective and objective risk were compared between respondents with different preferred information sources. Chi Square contingency tables and pair-wise correlation were used to evaluate differences to 95% confidence. For HCW and non-HCW, the greatest overestimation of personal COVID-19 risk assessment (

    Abstract Objective: This study aims to assess associations between morphine-equivalent daily dose (MEDD) of opioids, clinician and patient characteristics, and prescriber adherence to guidelines for long-term opioid therapy (LTOT) in chronic noncancer pain (CNCP) and to elucidate potential relationships associated with increased-risk opioid prescribing.
    Design: Retrospective cross-sectional study.
    Setting: Academic health system's 33 primary care clinics.
    Patients: Adults (≥18 years old) prescribed LTOT (10 + outpatient prescriptions in the past year) for CNCP.
    Main outcome measure(s): Electronic health record data on prescribed opioids (for MEDD), clinician/patient characteristics, and adherence rates to LTOT guideline-concordant recommendations.
    Results: A total of 2,738 patients were eligible, 61.6 percent Lower, 15.7 percent Moderate, and 22.7 percent Higher Risk MEDD (<50, 50-89, and ≥90 mg/day, respectively). Higher MEDD correlated (p < 0.001) with Medicare insurance, current cigarette smoking, higher pain intensity and interference scores, and the presence of opioid use disorder diagnoses. Male clinicians more frequently prescribed (p < 0.001) and male patients were more likely to be prescribed (p < 0.001) higher MEDD compared to their female counterparts. Higher Risk MEDD was associated with higher coprescribed benzodiazepines (p = 0.015), lower depression screening (p = 0.048), urine drug testing (p = 0.003), comparable active treatment agreement (p = 0.189), opioid misuse risk screening (p = 0.619), and prescription drug monitoring checks (p = 0.203).
    Conclusions: This study documented that higher MEDD was associated with risks of worse health outcomes without improved adherence to opioid prescribing guideline recommendations. Enhanced clinician awareness of factors associated with MEDD has the potential to mitigate LTOT risks and improve overall patient care.

    Abstract We derive a simple asymptotic approximation for the long-run case fatality rate of COVID-19 (alpha and delta variants) and show that these estimations are highly correlated to the interaction between US State median age and projected US unemployment rate (Adj. r2 = 60%). We contrast this to the high level of correlation between point (instantaneous) estimates of per state case fatality rates and the interaction of median age, population density and current unemployment rates (Adj. r2 = 50.2%). To determine whether this is caused by a "race effect," we then analyze unemployment, race, median age and population density across US states and show that adding the interaction of African American population and unemployment explains 53.5% of the variance in COVID case fatality rates for the alpha and delta variants when considering instantaneous case fatality rate. Interestingly, when the asymptotic case fatality rate is used, the dependence on the African American population disappears, which is consistent with the fact that in the long-run COVID does not discriminate on race, but may discriminate on access to medical care which is highly correlated to employment in the US. The results provide further evidence of the impact inequality can have on case fatality rates in COVID-19 and the impact complex social, health and economic factors can have on patient survival.
