RESUMO
BACKGROUND: Hypertension is a leading risk factor for cardiovascular disease among patients living with HIV (PLWH). Understanding the predictors and patterns of antihypertensive medication prescription and blood pressure (BP) control among PLWH with hypertension (HTN) is important to improve the primary prevention efforts for this high-risk population. We sought to identify important patient-level correlates for (e.g., race) and assess inter-facility variations in antihypertension medication prescriptions and BP control among Veterans living with HIV (VLWH) and HTN. METHODS: We studied VLWH with a diagnosis of HTN who received care in the Veterans Health Administration (VHA) from January 2018 to December 2019. We evaluated HTN treatment and blood pressure control across demographic variables, including race, and by medical comorbidities. Data were also compared among VHA facilities. Predictors of HTN treatment and control were assessed in two-level hierarchical multivariate logistic regression models to estimate odds ratios (ORs). The VHA facility random-effects parameters from the hierarchical models were used to calculate the median odds ratios to characterize the variation across the different VHA facilities. RESULTS: A total of 17,468 VLWH with HTN (mean age 61 years, 97% male, 54% Black, 40% White) who received care within the VHA facilities in 2018-2019 were included. 73% were prescribed antihypertension medications with higher prescription rates among Black versus White patients (75% vs. 71%) and higher prescription rates among patients with a history of cardiovascular disease, diabetes, and kidney disease (>80%), and those receiving antiretroviral therapy and with controlled HIV viral load (â¼75%). Only 27% of VLWH with HTN had optimal BP control of systolic BP <130 mmHg and diastolic BP <80 mmHg, with a lower rate of control among Black versus White patients (24% v. 31%). In multivariate regression, Black patients had a higher likelihood of HTN medication prescription (OR 1.32, 95% CI: 1.22-1.42 used Table 3) but were less likely to have optimal BP control (OR 0.82; 0.76-0.88). Important correlates of antihypertensive prescription and optimal BP control included: number of outpatient visits, and histories of diabetes, coronary artery disease, and heart failure. There was about 10% variability in both antihypertensive prescription and BP control patterns between VHA facilities for patients with similar characteristics. There was increased inter-facility variation antihypertensive prescription among those with a history of heart failure and those not receiving antiretroviral therapy. CONCLUSION: In a retrospective analysis of large VHA data, we found that VLWH with HTN have suboptimal antihypertensive medication prescription and BP control. Black VLWH had higher HTN medication prescription rates but lower optimal BP control.
RESUMO
BACKGROUND: People with HIV have increased atherosclerotic cardiovascular disease (ASCVD) risk, worse outcomes following incident ASCVD, and experience gaps in cardiovascular care, highlighting the need to improve delivery of preventive therapies in this population. OBJECTIVE: Assess patient-level correlates and inter-facility variations in statin prescription among Veterans with HIV and known ASCVD. METHODS: We studied Veterans with HIV and existing ASCVD, ie, coronary artery disease (CAD), ischemic cerebrovascular disease (ICVD), and peripheral arterial disease (PAD), who received care across 130 VA medical centers for the years 2018-2019. We assessed correlates of statin prescription using two-level hierarchical multivariable logistic regression. Median odds ratios (MORs) were used to quantify inter-facility variation in statin prescription. RESULTS: Nine thousand six hundred eight Veterans with HIV and known ASCVD (mean age 64.3 ± 8.9 years, 97% male, 48% Black) were included. Only 68% of the participants were prescribed any-statin. Substantially higher statin prescription was observed for those with diabetes (adjusted odds ratio [OR] = 2.3, 95% confidence interval [CI], 2.0-2.6), history of coronary revascularization (OR = 4.0, CI, 3.2-5.0), and receiving antiretroviral therapy (OR = 3.0, CI, 2.7-3.4). Blacks (OR = 0.7, CI, 0.6-0.9), those with non-coronary ASCVD, ie, ICVD and/or PAD only, (OR 0.53, 95% CI: 0.48-0.57), and those with history of illicit substance use (OR=0.7, CI, 0.6-0.9) were less likely to be prescribed statins. There was significant variation in statin prescription across VA facilities (10th, 90th centile: 55%, 78%), with an estimated 20% higher likelihood of difference in statin prescription practice for two clinically similar individuals treated at two comparable facilities (adjusted MOR = 1.21, CI, 1.18-1.24), and a greater variation observed for Blacks or those with non-coronary ASCVD or history of illicit drug use. CONCLUSION: In an analysis of large-scale VA data, we found suboptimal statin prescription and significant interfacility variation in statin prescription among Veterans with HIV and known ASCVD, particularly among Blacks and those with a history of non-coronary ASCVD.

Mucoepidermoid carcinoma is a rare neoplasm of the salivary gland of which the intraosseous variety is commonly observed with a female predilection and the affected side is more commonly in the mandible. It is usually perceived as an asymptomatic swelling that increases in volume over a few months to a year. They more frequently present as a cortical bulging and are mostly discovered as an accidental finding in a routine radiograph as a well-defined unilocular or multilocular radiolucency resembling an odontogenic cyst. The most widely accepted treatment is radical surgical resection due to its recurrence or metastatic nature. The current case is quite unusual developing in the posterior jaw as a result of an impacted third molar in a 22-year-old female patient.
RESUMO
Purpose: The objective of this case series is to highlight different manifestations of valacyclovir associated neurotoxicity (VAN) and demonstrate the importance of adjusting medication appropriately in patients with end-stage renal disease (ESRD) on hemodialysis to prevent these complications. Summary: Valacyclovir is a medication used to treat herpes zoster infection, commonly known as shingles. Valacyclovir is renally cleared and can accumulate in patients with renal dysfunction leading to severe side effects due to the prolonged half-life. VAN is a common adverse effect in patients with underlying kidney disease, that can be easily prevented if valacyclovir is properly dosed. This case series details the clinical outcomes of two elderly patients who were prescribed valacyclovir at six-times the recommended dose based on their renal function. Failure to reduce the dose of valacyclovir resulted in severe neurological and physical manifestations that required hospital admission and emergent hemodialysis. Conclusion: This case series details the importance of adjusting valacyclovir dose based on renal function. In patients with ESRD, the half-life of valacyclovir can be up to 14 hours, therefore hemodialysis should be utilized in severe cases of neurotoxicity to improve rapid excretion of the drug and promote rapid recovery from VAN.

INTRODUCTION: Gram-negative resistance is a well-acknowledged public health threat. Surveillance data can be used to monitor resistance trends and identify strategies to mitigate their threat. The objective of this study was to assess antibiotic resistance trends in Gram-negative bacteria. METHODS: The first cultures of Pseudomonas aeruginosa, Citrobacter, Escherichia coli, Enterobacter, Klebsiella, Morganella morganii, Proteus mirabilis, and Serratia marcescens per hospitalized patient per month collected from 125 Veterans Affairs Medical Centers (VAMCs) between 2011 to 2020 were included. Time trends of resistance phenotypes (carbapenem, fluoroquinolone, extended-spectrum cephalosporin, multi-drug, and difficult-to-treat) were analyzed with Joinpoint regression to estimate average annual percent changes (AAPC) with 95% confidence intervals and p values. A 2020 antibiogram of reported antibiotic percent susceptibilities was also created to evaluate resistance rates at the beginning of the COVID-19 pandemic. RESULTS: Among 40 antimicrobial resistance phenotype trends assessed in 494,593 Gram-negative isolates, there were no noted increases; significant decreases were observed in 87.5% (n = 35), including in all P. aeruginosa, Citrobacter, Klebsiella, M. morganii, and S. marcescens phenotypes (p < 0.05). The largest decreases were seen in carbapenem-resistant phenotypes of P. mirabilis, Klebsiella, and M. morganii (AAPCs: - 22.9%, - 20.7%, and - 20.6%, respectively). In 2020, percent susceptibility was over 80% for all organisms tested against aminoglycosides, cefepime, ertapenem, meropenem, ceftazidime-avibactam, ceftolozane-tazobactam, and meropenem-vaborbactam. CONCLUSION: We observed significant decreases in antibiotic resistance for P. aeruginosa and Enterobacterales over the past decade. According to the 2020 antibiogram, in vitro antimicrobial activity was observed for most treatment options. These results may be related to the robust infection control and antimicrobial stewardship programs instituted nationally among VAMCs.
RESUMO
Clostridium sporogenes bacteremia in immunocompetent patients is rare with very few reported cases in the literature. We present a case of Clostridium sporogenes bacteremia in an 81-year-old immunocompetent man with small bowel obstruction and hypoxemia during the COVID-19 pandemic. Routine monitoring of prognostic inflammatory markers for COVID-19 created a unique challenge in the management of our patient who developed sepsis with respiratory symptoms. Upon review, bacteremia from Clostridium sporogenes was associated with high mortality rates and could produce similar elevations in the inflammatory markers observed in COVID-19 pneumonia. Further, we reviewed the cognitive biases encountered when monitoring these inflammatory markers during the management of our patient with Clostridium sporogenes bacteremia, who was initially thought to have COVID-19 disease. While our patient ultimately tested negative for COVID-19, early administration of empiric antimicrobial therapy without source control failed to prevent clinical decompensation.
RESUMO
BACKGROUND: The outbreak of coronavirus disease 2019 (COVID-19) began in December 2019 and continues to spread worldwide. Rapid and accurate identification of suspected cases is critical in slowing spread of the virus that causes the disease. We aimed to highlight discrepancies in the various criteria used by international agencies and highly impacted individual countries around the world. METHODS: We reviewed the criteria for identifying a suspected case of COVID-19 used by two international public health agencies and 10 countries across Asia, Europe, and North America. The criteria included information on the clinical causes of illness and epidemiological risk factors. Non-English language guidelines were translated into English by a co-author who is fluent in that particular language. RESULTS: Although most criteria are modifications of World Health Organization recommendations, the specific clinical features and epidemiological risks for triggering evaluation of patients with suspected COVID-19 differed widely among countries. The rationale for these differences may be related to each country's resources, politics, experience with previous outbreaks or pandemics, health insurance system, COVID-19 outbreak severity, and other undetermined factors. CONCLUSION: We found no consensus regarding the best diagnostic criteria for identifying a suspected case of COVID-19.

Human immunodeficiency virus (HIV) has caused resurgence in tuberculosis (TB) worldwide. HIV-TB coinfected individuals are at increased risk for complications of TB and HIV treatment, such as adverse drug reactions and immune reconstitution syndrome. A 17-year-old male with HIV-TB coinfection, who developed cardiac tamponade from immune reconstitution during treatment for TB and HIV, is reported in this document.

BACKGROUND: Conflicting data exist on the role of antimicrobial therapy for the treatment of uncomplicated community-onset methicillin-resistant Staphylococcus aureus (MRSA) skin and soft-tissue infections (SSTIs). METHODS: We performed a retrospective cohort study of 492 adult patients with 531 independent episodes of community-onset MRSA SSTIs, which consisted of abscesses, furuncles/carbuncles, and cellulitis, at 2 tertiary care medical centers. The purpose of the study was to determine the impact of active antimicrobial therapy (i.e., the use of an agent to which the organism is susceptible) and other potential risk factors on the outcome for patients with uncomplicated community-onset MRSA SSTIs. Treatment failure was the primary outcome of interest and was defined as worsening signs of infection associated with microbiological and/or therapeutic indicators of an unsuccessful outcome. Bivariate analyses and logistic regression analyses were preformed to determine predictors of treatment failure. RESULTS: An incision and drainage procedure was performed for the majority of patients. Treatment failure occurred in 45 (8%) of 531 episodes of community-onset MRSA SSTI. Therapy was successful for 296 (95%) of 312 patients who received an active antibiotic, compared with 190 (87%) of 219 of those who did not (P=.001 in bivariate analysis). Use of an inactive antimicrobial agent was an independent predictor of treatment failure on logistic regression analysis (adjusted odds ratio, 2.80; 95% confidence interval, 1.26-6.22; P=.01). CONCLUSIONS: Our findings suggest that certain patients with SSTIs that are likely caused by MRSA would benefit from treatment with an antimicrobial agent with activity against this organism.

BACKGROUND: Few data exist on the efficacy of the long-acting tetracyclines doxycycline and minocycline against methicillin-resistant Staphylococcus aureus (MRSA) infection. METHODS: The medical records of 24 patients with serious tetracycline-susceptible MRSA infections who were treated with doxycycline or minocycline were reviewed. A review of the literature on the use of these antibiotics for treatment of both methicillin-susceptible and methicillin-resistant S. aureus infection was also performed. RESULTS: Complicated skin and skin-structure infections were most common (67%). Clinical cure was achieved in 20 (83%) of 24 patients in our case series. Both drugs were well-tolerated. The review of the literature on a total of 85 patients with S. aureus infection revealed similar results. CONCLUSIONS: Long-acting tetracyclines may be a reasonable treatment alternative for patients with certain types of MRSA infection.

Few data exist on the clinical utility of the expanded-spectrum tetracyclines doxycycline and minocycline for the treatment of community-associated methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections (SSTI). We performed a retrospective cohort study of 276 patients who presented with 282 episodes of MRSA SSTI to the emergency room or outpatient clinic at two tertiary medical centers between October 2002 and February 2007. The median percentage of patients infected with MRSA strains that were susceptible to tetracycline was 95%. Time zero was defined as the time of the first incision and drainage procedure or, if none was performed, the time of the first positive wound culture. The median patient age was 48 years. Abscesses constituted the majority of clinical presentations (75%), followed by furuncles or carbuncles (13%) and cellulitis originating from a purulent focus of infection (12%). A total of 225 patients (80%) underwent incision and drainage. Doxycycline or minocycline was administered in 90 episodes (32%); the other 192 SSTI were treated with beta-lactams. Treatment failure, defined as the need for a second incision and drainage procedure and/or admission to the hospital within at least 2 days after time zero, was diagnosed in 28 episodes (10%) at a median of 3 days after time zero. On logistic regression analysis, receipt of a beta-lactam agent was the only clinical characteristic associated with treatment failure (adjusted odds ratio, 3.94; 95% confidence interval, 1.28 to 12.15; P = 0.02). The expanded-spectrum tetracyclines appear to be a reasonable oral treatment option for patients with community onset MRSA SSTI in areas where MRSA strains are susceptible to the tetracyclines.
