RESUMO
Background: Antibiotic use is a major risk factor for recurrent Clostridioides difficile infection (CDI) due to the associated disruption in gut microbiota. Fecal microbiota, live-jslm (REBYOTA®; RBL, previously RBX2660), is the first microbiota-based live biotherapeutic approved by the US Food and Drug Administration to prevent recurrent CDI in adults following standard-of-care antibiotic treatment. To investigate the impact of non-CDI antibiotics on the durability of RBL, a subgroup analysis was conducted on PUNCH™ Open-Label study participants who received non-CDI antibiotics during the period between RBL administration and up to 2 years after. Methods: Participants in PUNCH™ Open-Label who received non-CDI antibiotics after RBL administration were included in this subgroup analysis. Treatment response was defined as the absence of CDI diarrhea needing retreatment at the last evaluable time point (8 weeks, 6 months, 1 year, or 2 years) after RBL administration. Results: Among participants from PUNCH™ Open-Label, 43 received non-CDI antibiotics after RBL administration but before CDI recurrence as evaluated over a 2-year period. Across all evaluable time points, 86% (37/43) of participants had a treatment response regardless of when non-CDI antibiotic exposure occurred. Treatment response was sustained for a median 470 days (IQR, 212-648) from the first day of non-CDI antibiotic use. Most participants (5/6) with CDI recurrences received a high-risk antibiotic. Conclusions: RBL remained efficacious in participants with a history of recurrent CDI after subsequent non-CDI antibiotic exposure. Clinical Trials Registration: NCT02589847 (https://clinicaltrials.gov/study/NCT02589847).
RESUMO
Emerging data support associations between the depletion of the healthy gut microbiome and aging-related physiological decline and disease. In humans, fecal microbiota transplantation (FMT) has been used successfully to restore gut microbiome structure and function and to treat C. difficile infections, but its application to healthy aging has been scarcely investigated. The marmoset is an excellent model for evaluating microbiome-mediated changes with age and interventional treatments due to their relatively shorter lifespan and many social, behavioral, and physiological functions that mimic human aging. Prior work indicates that FMT is safe in marmosets and may successfully mediate gut microbiome function and host health. This narrative review (1) provides an overview of the rationale for FMT to support healthy aging using the marmoset as a translational geroscience model, (2) summarizes the prior use of FMT in marmosets, (3) outlines a protocol synthesized from prior literature for studying FMT in aging marmosets, and (4) describes limitations, knowledge gaps, and future research needs in this field.
RESUMO
Introduction: Sexually transmitted infections (STIs) continue to increase in the United States and pregnant patients who acquire STIs are at risk for serious complications. This study estimated the utilization of preventative STI testing among pregnant outpatients on a national scale. Methods: This was a retrospective, cross-sectional study of outpatient visits in the National Ambulatory Medical Care Survey from 2014 to 2016 and 2018 to 2019. All patients reported as pregnant were included to assess STI testing for chlamydia, gonorrhea, hepatitis, and HIV. STI testing was described per 1,000 total visits overall and by subpopulations. Data weights were applied to generate national estimates. Results: Over 177 million visits were included, of which 87.5 per 1,000 included an STI test. Chlamydia testing was the most common, followed by HIV, gonorrhea, and hepatitis (58.0 vs. 42.3 vs. 41.5 vs. 20.3 per 1,000). STI testing rates varied across subpopulations (72.1-236.6 per 1,000 visits). Patients of Hispanic ethnicity, Black race, age ≤25 years old, and those seen by an obstetrics and gynecology (OB/GYN) provider had the highest rates of STI testing. Independent predictors of STI testing included: Black race (adjusted odds ratio [aOR]: 2.24, 95% confidence interval [95% CI]: 2.23-2.24), first trimester (aOR: 5.15, 95% CI: 5.14-5.16), government and private insurance (aOR: 1.90, 95% CI: 1.89-1.91 and aOR: 1.70, 95% CI: 1.69-1.71), and an OB/GYN provider specialty (aOR: 2.93, 95% CI: 2.93-2.94). Conclusions: STI testing in United States outpatient physician offices varied by subpopulations and across individual test types. Certain patient attributes, such as race, provider specialty, and payment source, were predictive of testing.
RESUMO
Objectives: Recent data suggest concomitant gabapentinoid use increases opioid-related overdose (ORO) risk; however, this association has not been well studied in the hospital setting. The primary objective of this study was to compare ORO risk, indicated by naloxone administration, in patients receiving opioids plus gabapentinoids versus opioids alone. Methods: In this retrospective case-control study of adults admitted to a large community hospital from 1/1/20 to 12/31/21, all cases (defined as patients who received naloxone more than 24 hours after admission) identified were matched 1:1 to randomly selected controls (defined as patients on opioids who did not receive naloxone). The primary outcome was the percentage of cases and controls with concomitant inpatient gabapentinoid use. Logistic regression was performed to determine the independent association between gabapentinoids and ORO (as evidenced by inpatient naloxone administration). Results: Baseline characteristics were similar between the 144 cases and 144 controls. Gabapentinoid exposure was greater for cases than controls (34.0%vs 20.8%, P = .0118). Median hospital length of stay (11vs 4 days, P < .0001) and mortality (19%vs 5%; P = .0018) were also higher for cases. In logistic regression analysis, ORO (adjusted OR 4.91; 95% CI 1.86-12.96) and serotonergic medication exposure (adjusted OR 4.31; 95% CI 1.50-12.38) were significantly associated with gabapentinoid use. Conclusions: Concomitant gabapentinoid use with opioids was associated with increased ORO risk in the inpatient setting. When considering prescribing gabapentinoids in conjunction with opioids in the hospital setting, potential benefits should be weighed against increased overdose risk.
RESUMO
Among carbapenem-resistant Enterobacterales (CRE) are diverse mechanisms, including those that are resistant to meropenem but susceptible to ertapenem, adding further complexity to the clinical landscape. This study investigates the emergence of ertapenem-resistant, meropenem-susceptible (ErMs) Escherichia coli and Klebsiella pneumoniae CRE across five hospitals in San Antonio, Texas, USA, from 2012 to 2018. The majority of the CRE isolates were non-carbapenemase producers (NCP; 54%; 41/76); 56% of all NCP isolates had an ErMs phenotype. Among ErMs strains, E. coli comprised the majority (72%). ErMs strains carrying blaCTX-M had, on average, 9-fold higher copies of blaCTX-M than CP-ErMs strains as well as approximately 4-fold more copies than blaCTX-M-positive but ertapenem- and meropenem-susceptible (EsMs) strains (3.7 vs. 0.9, p < 0.001). Notably, carbapenem hydrolysis was observed to be mediated by strains harboring blaCTX-M with and without a carbapenemase(s). ErMs also carried more mobile genetic elements, particularly IS26 composite transposons, than EsMs (37 vs. 0.2, p < 0.0001). MGE- ISVsa5 was uniquely more abundant in ErMs than either EsMs or ErMr strains, with over 30 more average ISVsa5 counts than both phenotype groups (p < 0.0001). Immunoblot analysis demonstrated the absence of OmpC expression in NCP-ErMs E. coli, with 92% of strains lacking full contig coverage of ompC. Overall, our findings characterize both collaborative and independent efforts between blaCTX-M and OmpC in ErMs strains, indicating the need to reappraise the term "non-carbapenemase (NCP)", particularly for strains highly expressing blaCTX-M. To improve outcomes for CRE-infected patients, future efforts should focus on mechanisms underlying the emerging ErMs subphenotype of CRE strains to develop technologies for its rapid detection and provide targeted therapeutic strategies.
RESUMO
Oral health plays a significant role in the quality of life and overall well-being of the aging population. However, age-related changes in oral health are not well understood due to challenges with current animal models. In this study, we analyzed the oral health and microbiota of a short-lived non-human primate (i.e., marmoset), as a step towards establishing a surrogate for studying the changes that occur in oral health during human aging. We investigated the oral health of marmosets using cadaveric tissues in three different cohorts: young (aged ≤6 years), middle-aged, and older (>10 years) and assessed the gingival bacterial community using analyses of the V3-V4 variable region of 16S rRNA gene. The oldest cohort had a significantly higher number of dental caries, increased dental attrition/erosion, and deeper periodontal pocket depth scores. Oral microbiome analyses showed that older marmosets had a significantly greater abundance of Escherichia-Shigella and Propionibacterium, and a lower abundance of Agrobacterium/Rhizobium at the genus level. Alpha diversity of the microbiome between the three groups showed no significant differences; however, principal coordinate analysis and non-metric multidimensional scaling analysis revealed that samples from middle-aged and older marmosets were more closely clustered than the youngest cohort. In addition, linear discriminant analysis effect size (LEFSe) identified a higher abundance of Esherichia-Shigella as a potential pathogenic biomarker in older animals. Our findings confirm that changes in the oral microbiome are associated with a decline in oral health in aging marmosets. The current study suggests that the marmoset model recapitulates some of the changes in oral health associated with human aging and may provide opportunities for developing new preventive strategies or interventions which target these disease conditions.

Infectious diseases are a leading contributor to death in the United States, and racial differences in clinical outcomes have been increasingly reported. Clostridioides difficile infection (CDI) is a growing public health concern, as it causes nearly half a million infections per year and considerable excess hospital costs. Concurrent with other infectious diseases, recent literature denotes racial disparities in CDI incidence rates, mortality, and associated morbidity. Of note, investigations into CDI and causative factors suggest that inequities in health-related social needs and other social determinants of health (SDoH) may cause disruption to the gut microbiome, thereby contributing to the observed deleterious outcomes in racially and ethnically minoritized individuals. Despite these discoveries, there is limited literature that provides context for the recognized racial disparities in CDI, particularly the influence of structural and systemic barriers. Here, we synthesize the available literature describing racial inequities in CDI outcomes and discuss the interrelationship of SDoH on microbiome dysregulation. Finally, we provide actionable considerations for infectious diseases professionals to aid in narrowing CDI equity gaps.

Background: Next-generation sequencing (NGS) methods for microbial profiling have increased sensitivity to detect urinary pathogens. Objective: To determine whether NGS microbial profiling can be used to guide antibiotic prophylaxis and reduce infection compared with the standard of care. Design setting and participants: A prospective randomized controlled clinical trial of patients undergoing urologic stone interventions at an academic health center from December 2019 to January 2022 was conducted. Urine was collected at the preoperative visit for standard culture and intervention NGS diagnostics. Evaluable patients were culture negative, met 2-wk follow-up, and did not cancel surgery. Of 240 individuals (control = 121, intervention = 119), 83 control and 74 intervention patients were evaluable. Intervention: Microbial findings (paired quantitative polymerase chain reaction and NGS) were sent to an infectious disease pharmacist to recommend prophylactic antimicrobial regimen. Outcome measurements and statistical analysis: The primary outcome was postoperative urinary infection within the follow-up period (Fisher's exact test). The primary outcome was analyzed by modified intent-to-treat (mITT) and per-protocol analyses. Secondary endpoints considered included positive culture concordance, antibiotic use, and adverse events. Additional post hoc analyses investigated factors contributing to infection (univariate logistic regression). Results and limitations: The intervention significantly reduced postsurgical urinary infection risk by 7.1% (-0.73%, 15%) compared with the standard of care in the mITT analysis (1.4% vs 8.4%, p = 0.045) or by 8.5% (0.88%, 16%) compared with the per-protocol analysis (0% vs 8.5%, p = 0.032). NGS-guided treatment altered the distribution of antibiotics used (p = 0.025), and antibiotics poorly matched with NGS findings were associated with increased infection odds (odds ratio [OR] = 5.9, p = 0.046). Women were at greater odds to develop infection (OR = 10, p = 0.03) and possessed differentiated microbial profiles (p < 0.001). Conclusions: Urinary microbial NGS-guided antibiotic prophylaxis before endoscopic urologic stone lithotripsy improves antibiotic selection to reduce healthcare-associated urinary infections; however, treatment efficacy may be limited by the ability to adhere to the recommended protocol. Patient summary: We investigated whether microbial DNA sequencing could improve the selection of antibiotics before kidney stone surgery in patients not known to have any bacteria in the urine on standard culture. We found that using microbe DNA to guide antibiotic choices decreased postoperative infection rate and may encourage individualized use of available antibiotics.
RESUMO
BACKGROUND: Durvalumab is approved for the treatment of adults with unresectable stage III non-small cell lung cancer (NSCLC) post-chemoradiotherapy (CRT). This real-world study describes patient characteristics and durvalumab treatment patterns (number of doses and therapy duration; treatment initiation delays, interruptions, discontinuations, and associated reasons) among VHA-treated patients. METHODS: This was a retrospective cohort study of adults with unresectable stage III NSCLC receiving durvalumab at the VHA between 1 January 2017 and 30 June 2020. Patient characteristics and treatment patterns were presented descriptively. RESULTS: A total of 935 patients were included (median age: 69 years; 95% males; 21% Blacks; 46% current smokers; 16% ECOG performance scores ≥ 2; 50% squamous histology). Durvalumab initiation was delayed in 39% of patients (n = 367). Among the 200 patients with recorded reasons, delays were mainly due to physician preference (20%) and CRT toxicity (11%). Overall, patients received a median (interquartile range) of 16 (7-24) doses of durvalumab over 9.0 (2.9-11.8) months. Treatment interruptions were experienced by 19% of patients (n = 180), with toxicity (7.8%) and social reasons (2.6%) being the most cited reasons. Early discontinuation occurred in 59% of patients (n = 551), largely due to disease progression (24.2%) and toxicity (18.2%). CONCLUSIONS: These real-world analyses corroborate PACIFIC study results in terms of the main reasons for treatment discontinuation in a VHA population with worse prognostic factors, including older age, predominantly male sex, and poorer performance score. One of the main reasons for durvalumab initiation delays, treatment interruptions, or discontinuations was due to toxicities. Patients could benefit from improved strategies to prevent, identify, and manage CRT and durvalumab toxicities timely and effectively.
RESUMO
Despite efforts to dissuade major manufacturers and retailers from marketing and selling vape products to adolescents, the practice of vaping continues to increase in this population. Few studies have assessed adolescent perceptions of vaping, access to vaping, and use of vaping, and most rely, at least in part, on inferential conclusions drawn from data on smoking traditional combustible cigarettes. A novel electronic survey was created to assess the use of vapes, perceptions of vaping, and access to vaping among a convenience sample of adolescents (ages 12-20 years) in eleven schools in South-Central Texas from May to August 2021. The students' perceived threat of negative health outcomes due to vaping was calculated based on questions soliciting perceptions of severity (perceived danger) and susceptibility (perceived likelihood of illness). Trends were identified using descriptive and bivariate statistical tests. A total of 267 respondents were included; 26% had tried vaping. A majority (63%) did not believe vaping and smoking were synonymous. Most (70%) thought it was easy to obtain supplies and (76%) vape before and after (88%) or even during (64%) school. Respondents who vaped had a 34% lower perceived threat when compared to respondents who did not vape. In this sample of adolescents from South-Central Texas, one in four reported that they had tried vaping. Easy access to vapes and misperceptions regarding the safety of vaping might create a false sense of security with respect to vaping as an alternative to smoking, particularly among those who reported vaping, and is likely contributing to the increased use of vapes.

BACKGROUND: Real-world evidence is limited regarding the relationship between race and use of durvalumab, an immunotherapy approved for use in adults with unresectable stage III non-small cell lung cancer (NSCLC) post-chemoradiotherapy (CRT). This study aimed to evaluate if durvalumab treatment patterns differed by race in patients with unresectable stage III NSCLC in a Veterans Health Administration (VHA) population. MATERIALS AND METHODS: This was a retrospective analysis of White and Black adults with unresectable stage III NSCLC treated with durvalumab presenting to any VHA facility in the US from January 1, 2017, to June 30, 2020. Data captured included baseline characteristics and durvalumab treatment patterns, including treatment initiation delay (TID), interruption (TI), and discontinuation (TD); defined as CRT completion to durvalumab initiation greater than 42 days, greater than 28 days between durvalumab infusions, and more than 28 days from the last durvalumab dose with no new durvalumab restarts, respectively. The number of doses, duration of therapy, and adverse events were also collected. RESULTS: A total of 924 patients were included in this study (White = 726; Black = 198). Race was not a significant factor in a multivariate logistic regression model for TID (OR, 1.39; 95% CI, 0.81-2.37), TI (OR, 1.58; 95% CI, 0.90-2.76), or TD (OR, 0.84; 95% CI, 0.50-1.38). There were also no significant differences in median (interquartile range [IQR]) number of doses (White: 15 [7-24], Black: 18 [7-25]; P = .25) or median (IQR) duration of therapy (White: 8.7 months [2.9-11.8], Black: 9.8 months [3.6-12.0]; P = .08), although Black patients were less likely to experience an immune-related adverse event (28% vs. 36%, P = .03) and less likely to experience pneumonitis (7% vs. 14%, P < .01). CONCLUSION: Race was not found to be linked with TID, TI, or TD in this real-world study of patients with unresectable stage III NSCLC treated with durvalumab at the VHA.

INTRODUCTION: Up to 35% of patients with a first episode of Clostridioides difficile infection (CDI) develop recurrent CDI (rCDI), and of those, up to 65% experience multiple recurrences. A systematic literature review (SLR) was conducted to review and summarize the economic impact of rCDI in the United States of America. METHODS: English-language publications reporting real-world healthcare resource utilization (HRU) and/or direct medical costs associated with rCDI in the USA were searched in MEDLINE, MEDLINE In-Process, Embase, and the Cochrane Library databases over the past 10 years (2012-2022), as well as in selected scientific conferences that publish research on rCDI and its economic burden over the past 3 years (2019-2022). HRU and costs identified through the SLR were synthesized to estimate annual rCDI-attributable direct medical costs to inform the economic impact of rCDI from a US third-party payer's perspective. RESULTS: A total of 661 publications were retrieved, and 31 of them met all selection criteria. Substantial variability was found across these publications in terms of data source, patient population, sample size, definition of rCDI, follow-up period, outcomes reported, analytic approach, and methods to adjudicate rCDI-attributable costs. Only one study reported rCDI-attributable costs over 12 months. Synthesizing across the relevant publications using a component-based cost approach, the per-patient per-year rCDI-attributable direct medical cost was estimated to range from $67,837 to $82,268. CONCLUSIONS: While real-world studies on economic impact of rCDI in the USA suggested a high-cost burden, inconsistency in methodologies and results reporting warranted a component-based cost synthesis approach to estimate the annual medical cost burden of rCDI. Utilizing available literature, we estimated the average annual rCDI-attributable medical costs to allow for consistent economic assessments of rCDI and identify the budget impact on US payers.

BACKGROUND: Acute agitation accounts for up to 2.6% of visits to the emergency department (ED). To date, a standard of care for the management of acute agitation has not been established. Few studies have evaluated antipsychotic and benzodiazepine combinations. OBJECTIVE: The purpose of this study was to evaluate effectiveness and safety of combination therapy for acute agitation with intramuscular (IM) droperidol and midazolam (D+M) compared with IM haloperidol and lorazepam (H+L) in patients in the ED. METHODS: This was a single-center, retrospective medical record review of patients presenting to a large, academic ED with acute agitation from July 2020 through October 2021. The primary outcome was percentage of patients requiring additional agitation medication within 60 minutes of combination administration. Secondary outcomes included average time to repeat dose administration and average number of repeat doses required before ED discharge. RESULTS: A total of 306 patients were included for analysis: 102 in the D+M group and 204 in the H+L group. Repeat dose within 60 minutes occurred in 7 (6.9%) and 28 (13.8%) patients in the D+M and H+L groups, respectively (P = 0.065). A total of 28.4% of D+M patients and 30.9% of H+L patients required any repeat dose during their ED visit. Time to repeat dose was 12 and 24 minutes in the D+M and H+L, respectively (P = 0.22). The adverse event rate was 2.9% in each group. CONCLUSION AND RELEVANCE: IM D+M resulted in a lower rate of repeat doses of acute agitation medication compared with IM H+L, though this was not statistically significant. Both therapies were safe, and the adverse event rate was low.

Clostridioides difficile remains a problematic pathogen resulting in significant morbidity and mortality, especially for high-risk groups that include immunocompromised patients. Both the Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America (IDSA/SHEA), as well as the American College of Gastroenterology (ACG) and the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) recently provided guideline updates for C. difficile infection (CDI). In this narrative review, the authors reviewed available literature regarding the prevention or treatment of CDI in adults and focused on disagreements between the IDSA/SHEA and ACG guidelines, as well as articles that have been published since the updates. Several options for primary prophylaxis are available, including probiotics and antibiotics (vancomycin, fidaxomicin). The literature supporting fidaxomicin is currently quite limited. While there are more studies evaluating probiotics and vancomycin, the optimal patient populations and regimens for their use have yet to be defined. While the IDSA/SHEA guidelines discourage metronidazole use for mild CDI episodes, evidence exists that it may remain a reasonable option for these patients. Fidaxomicin has an advantage over vancomycin in reducing recurrences, but its use is limited by cost. Despite this, recent studies suggest fidaxomicin's cost-effectiveness as a first-line therapy, though this is highly dependent on institutional contracts and payment structures. Secondary prophylaxis should focus on non-antimicrobial options to lessen the impact on the microbiome. The oral option of fecal microbiota transplantation (FMT), SER109, and the now FDA-approved RBX2660 represent exciting new options to correct dysbiosis. Bezlotoxumab is another attractive option to prevent recurrences. Further head-to-head studies of newer agents will be needed to guide selection of the optimal therapies for CDI primary and secondary prophylaxis.
RESUMO
INTRODUCTION: Urinary tract infections (UTIs) pose a significant health care burden. Outpatient antibiotic geospatial factors (eg, geographic prescribing and geographic resistance) may be associated with inpatient outcomes. This study examined the relationship between these factors, severe UTI, and hospitalization for severe UTI. METHODS: The first cohort included hospitalized, female, Medicare beneficiaries, aged >50 years. The primary outcome was severe UTI (defined as CSS diagnosis code of 159 with an APR-DRG severity of illness code of 3 or 4). The association between geospatial first-line prescribing (FLP) and severe UTI was assessed. The second cohort examined the association between these geospatial FLP and risk of hospitalization with severe UTI. Multivariable regression was used to produce adjusted odds ratios and adjusted risk ratios. RESULTS: In the first cohort (n = 14,474), low FLP was not associated with severe UTI (P = .87) in univariable analysis. In multivariable analysis, low FLP was associated with severe UTI was (aOR: 1.08 [95% CI 1.00, 1.16]). In the second cohort (n = 2,972,174), the admission rate was 47.0 and 49.8 per 10,000 (low FLP vs high FLP, respectively [P < .001]). The aRR for admission was 1.26 (95% CI 1.14, 1.39) in areas with low FLP. CONCLUSIONS: This study suggests that geospatial antibiotic factors may influence inpatient outcomes in women aged >50 with UTI. Further research is needed to corroborate our findings.

Antibiotic-associated acute kidney injury (AA-AKI) is quite common, especially among hospitalized patients; however, little is known about risk factors or mechanisms of why AA-AKI occurs. In this review, the authors have reviewed all available literature prior to 1 June 2022, with a large number of AKI reports. Information regarding risk factors of AA-AKI, mechanisms behind AA-AKI, and treatment/management principles to decrease AA-AKI risk were collected and reviewed. Patients treated in the inpatient setting are at increased risk of AA-AKI due to common risk factors: hypovolemia, concomitant use of other nephrotoxic medications, and exacerbation of comorbid conditions. Clinicians should attempt to correct risk factors for AA-AKI, choose antibiotic therapies with decreased association of AA-AKI to protect their high-risk patients, and narrow, when clinically possible, the use of antibiotics which have decreased incidence of AKI. To treat AKI, it is still recommended to discontinue all offending nephrotoxic agents and to renally adjust all medications according to package insert recommendations to decrease patient harm.
RESUMO
Background: The coronavirus disease 2019 (COVID-19) pandemic resulted in unprecedented emphasis on infection control procedures; however, it is unknown whether the pandemic altered Clostridioides difficile infection (CDI) prevalence. This study investigated CDI prevalence before and during the COVID-19 pandemic in a national sample of United States (US) hospitals. Methods: This was a retrospective cohort study using the Premier Healthcare Database. Patients with laboratory-confirmed CDI from April 2019 through March 2020 (pre-COVID-19 period) and April 2020 through March 2021 (COVID-19 period) were included. CDI prevalence (CDI encounters per 10 000 total encounters) and inpatient outcomes (eg, mortality, hospital length of stay) were compared between pre-COVID-19 and COVID-19 periods using bivariable analyses or interrupted time series analysis. Results: A total of 25 992 CDI encounters were included representing 22 130 unique CDI patients. CDI prevalence decreased from the pre-COVID-19 to COVID-19 period (12.2 per 10 000 vs 8.9 per 10 000, P < .0001), driven by a reduction in inpatient CDI prevalence (57.8 per 10 000 vs 49.4 per 10 000, P < .0001); however, the rate ratio did not significantly change over time (RR, 1.04 [95% confidence interval, .90-1.20]). From the pre-COVID-19 to COVID-19 period, CDI patients experienced higher inpatient mortality (5.5% vs 7.4%, P < .0001) and higher median encounter cost ($10 832 vs $12 862, P < .0001). Conclusions: CDI prevalence decreased during the COVID-19 pandemic in a national US sample, though at a rate similar to prior to the pandemic. CDI patients had higher inpatient mortality and encounter costs during the pandemic.
RESUMO
Clostridioides difficile infection (CDI) disproportionately affects certain populations, but few studies have investigated health outcome disparities among patients with CDI. This study aimed to characterize CDI treatment and health outcomes among patients by age group, sex, race, and ethnicity. This was a nationally representative, retrospective cohort study of patients with laboratory-confirmed CDI within the Premier Healthcare Database from January 2018 to March 2021. CDI therapies received and health outcomes were compared between patients by age group, sex, race, and Hispanic ethnicity using bivariable and multivariable statistical analyses. A total of 45,331 CDI encounters were included for analysis: 38,764 index encounters and 6567 recurrent encounters. CDI treatment patterns, especially oral vancomycin use, varied predominantly by age group. Older adult (65+ years), male, Black, and Hispanic patients incurred the highest treatment-related costs and were at greatest risk for severe CDI. Male sex was an independent predictor of in-hospital mortality (aOR 1.17, 95% CI 1.05−1.31). Male sex (aOR 1.25, 95% CI 1.18−1.32) and Black race (aOR 1.29, 95% CI 1.19−1.41) were independent predictors of hospital length of stay >7 days in index encounters. In this nationally representative study, CDI treatment and outcome disparities were noted by age group, sex, and race.
RESUMO
BACKGROUND: Recent evidence has identified limited naloxone accessibility in community pharmacies. OBJECTIVES: To summarize current literature regarding naloxone accessibility without an outside prescription from U.S. community pharmacies and discuss implications on community pharmacists' ability to mitigate the opioid overdose epidemic. METHODS: A systematic review was developed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed was searched up to May 12, 2022. References from articles chosen for inclusion were subsequently reviewed to identify additional relevant studies. Peer-reviewed publications reporting new data regarding the accessibility of naloxone from U.S. community pharmacies without an outside prescription (e.g., standing order, protocol) were included. Review articles and articles written in a non-English language were excluded. Individual study data were reported, along with a qualitative discussion of limitations of individual studies and in aggregate. When possible, naloxone accessibility data were also pooled and reported as overall accessibility and further stratified by chain versus independent pharmacies and urban versus rural settings. RESULTS: Thirty studies were included. Naloxone was in stock in 6867 of 10,934 (62.8%) pharmacies, though this varied greatly between studies (range, 26.4%-96.1%). Chain pharmacies were more likely to stock naloxone than independents (69.7% [range, 35.4%-89.1%] vs. 36.4% [range, 19.1%-89.7%], P < 0.0001). Stocking did not significantly differ between urban and rural locations. A total of 5660 of 8999 (62.9%; range, 23.5%-97%) pharmacies audited were willing to dispense without a prescription, with chain (67.4% vs. 22.2%, P < 0.0001) and rural (69.3% vs. 40.7%, P < 0.0001) pharmacies more likely than independent and urban, respectively. Key access barriers identified included naloxone not stocked, high naloxone cost, and pharmacist misinformation or stigma. CONCLUSION: Though limited by study heterogeneity, analysis of thirty U.S. studies revealed naloxone was available without a prescription in less than two-thirds of community pharmacies. Availability varied significantly by study and pharmacy type.

INTRODUCTION: It is unknown whether infectious diseases consultation improves outcomes for enterococcal bacteraemia in a multicentre healthcare system. METHODS: This retrospective multicentre observational cohort study included 250 adult patients with enterococcal bacteraemia between July 2016 and December 2020. The primary endpoint was a composite of clinical failure, including persistent bacteraemia, persistent fever, and in-hospital mortality. Secondary endpoints included adherence to a treatment bundle (appropriate empiric and definitive antibiotics, appropriate planned treatment duration, obtaining repeat blood cultures and an echocardiogram). RESULTS: Clinical failure occurred in 35 of 155 patients (22.6%) with an infectious diseases consultation and 16 of 95 patients (16.8%) without an infectious diseases consultation (P = 0.274). Multivariate analysis identified vasopressors as the only independent predictor of the primary outcome. Infectious diseases consultation resulted in higher adherence to a treatment bundle, including echocardiogram (75.5% vs. 34.7%; P < 0.0001), repeat blood cultures (85.2% vs. 68.4%; P = 0.002), appropriate definitive antibiotics (70.5% vs. 91.6%; P < 0.0001) and appropriate planned durations of therapy (81.1% vs. 94.2%; P = 0.001). More patients in the consult group were treated with ampicillin (47.1% vs. 22.1%; P < 0.0001) and fewer were treated with vancomycin (17.4% vs. 24.2%; P = 0.068). CONCLUSION: Despite finding no difference in clinical failure between groups, this study highlights important benefits of infectious diseases consultation in enterococcal bacteraemia.
