The pandemic's prescribing trends highlight general practitioners and gynecologists as the primary dispensers of azithromycin and ceftriaxone, thus identifying them as potential beneficiaries of antimicrobial stewardship programs.
The risk of infections resistant to drugs is augmented by colonization with antimicrobial-resistant bacteria. We discovered possible risk factors for human colonization with extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE) in the low-income urban and rural regions of Kenya.
Respondents in urban (Kibera, Nairobi County) and rural (Asembo, Siaya County) communities were sampled randomly for a cross-sectional study between January 2019 and March 2020, providing fecal specimens and demographic and socioeconomic data. Confirmed ESCrE isolates' antibiotic susceptibility was determined by employing the VITEK2 instrument. Plant cell biology A path analytic model was employed to pinpoint possible risk factors associated with colonization by ESCrE. In order to minimize the impact of household clustering, only one participant from each household was enrolled.
Data from 1148 adults (age 18) and 268 children (under 5 years of age) were gathered by examining their stool samples. A 12% rise in the probability of colonization was observed with more frequent hospital and clinic visits. Correspondingly, poultry-owning individuals had a 57% increased risk of ESCrE colonization compared to those not involved in poultry ownership. The presence of ESCrE colonization in respondents may be related to a complex interplay of factors, including respondents' characteristics such as sex and age, sanitation usage, rural/urban residence, healthcare contacts, and poultry keeping. Our analysis found no statistically significant connection between prior antibiotic use and ESCrE colonization.
The susceptibility to ESCrE colonization in communities hinges on healthcare- and community-related risk factors, necessitating integrated interventions at both community and hospital levels for controlling antimicrobial resistance effectively.
Communities experiencing ESCrE colonization face risk factors that intertwine healthcare and community elements. Consequently, interventions focused on both community and hospital levels are crucial for managing antimicrobial resistance.
We assessed the proportion of extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE) and carbapenem-resistant Enterobacterales (CRE) colonization in a hospital and surrounding communities in western Guatemala.
During the COVID-19 pandemic, from March to September 2021, randomly selected infants, children, and adults (under 1 year, 1 to 17 years, and 18 years and older, respectively) were enlisted from the hospital (n=641). A three-stage cluster design was employed to enroll community participants in two phases: phase one (November 2019 to March 2020, n=381), and phase two (July 2020 to May 2021, n=538) during the COVID-19 pandemic. To categorize stool samples as ESCrE or CRE, a Vitek 2 instrument analyzed samples that were initially streaked on selective chromogenic agar. Prevalence estimates were calculated with weights that were calibrated to the sampling design.
The proportion of patients colonized with ESCrE and CRE within the hospital environment was significantly higher than in the community setting (ESCrE: 67% vs 46%, P < .01). Analysis revealed a statistically significant difference (P < .01) in CRE prevalence, showing 37% versus 1%. Zenidolol Adult patients in the hospital showed a more frequent occurrence of ESCrE colonization (72%) than children (65%) and infants (60%), a statistically significant disparity (P < .05). In the community, adult colonization rates (50%) were significantly higher than those of children (40%), (P < .05). There was no variation in the ESCrE colonization rate between the initial (phase 1) and subsequent (phase 2) stages (45% and 47%, respectively, P > .05). Reports indicate a decrease in the use of antibiotics by households (23% and 7%, respectively, P < .001).
Hospitals continue to be crucial environments for the presence of Extended-Spectrum Cephalosporin-resistant Escherichia coli (ESCrE) and Carbapenem-resistant Enterobacteriaceae (CRE), thus emphasizing the need for infection control strategies; the considerable prevalence of ESCrE observed in the community, as reported in this study, might amplify colonization pressures and the risk of transmission within healthcare settings. Improved knowledge of transmission dynamics and age-related elements is necessary.
Hospitals, while consistently implicated in the presence of extended-spectrum cephalosporin-resistant Enterobacteriaceae (ESCrE) and carbapenem-resistant Enterobacteriaceae (CRE), demanding robust infection control practices, this study indicated a high prevalence of ESCrE within the wider community, potentially amplifying colonization pressures and transmission risks in healthcare environments. A deeper comprehension of transmission dynamics and age-specific factors is crucial.
This retrospective cohort study aimed to evaluate the influence of using polymyxin empirically as treatment for carbapenem-resistant gram-negative bacteria (CR-GNB) in septic patients on mortality. The tertiary academic hospital in Brazil served as the site for the study, conducted from January 2018 through January 2020, encompassing the pre-coronavirus disease 2019 timeframe.
Our research involved a group of 203 patients where sepsis was a possible diagnosis. The first antibiotic doses, sourced from a sepsis antibiotic kit which included polymyxin, were administered with no pre-approval policy. We built a logistic regression model to evaluate the risk factors driving 14-day crude mortality rates. Employing a propensity score model addressed potential biases in the polymyxin context.
Infections with at least one multidrug-resistant organism were observed in 70 (34%) of the 203 patients sampled, based on clinical culture results. Polymyxin therapy, in either a monotherapy or combination approach, was administered to 140 of the 203 (69%) patients. After fourteen days, the rate of death reached a significant 30% mark. A connection was observed between age and the 14-day crude mortality rate, specifically an adjusted odds ratio of 103 (confidence interval 101-105, p = .01). The SOFA (sepsis-related organ failure assessment) score, equaling 12 (aOR = 12; 95% CI = 109-132; P < .001), showcased a considerable impact. The adjusted odds ratio (aOR) for CR-GNB infection was 394 (95% confidence interval [CI] 153-1014), demonstrating statistical significance (P = .005). The odds ratio for the time between a suspected case of sepsis and antibiotic administration was 0.73 (95% confidence interval, 0.65 to 0.83; P < 0.001). Empirical polymyxin use showed no impact on reducing crude mortality; the adjusted odds ratio was 0.71 (95% confidence interval: 0.29 to 1.71). There is a 44% probability assigned to the event P.
The routine administration of polymyxin to septic patients in a setting with a high prevalence of carbapenem-resistant Gram-negative bacteria (CR-GNB) did not translate to a reduction in unadjusted mortality.
Despite a significant presence of carbapenem-resistant Gram-negative bacteria (CR-GNB) in the study environment, the routine use of polymyxin in septic patients did not translate to a lower crude mortality rate.
Comprehending the global burden of antibiotic resistance is challenging due to incomplete surveillance, especially within resource-constrained settings. With sites spanning six resource-poor settings, the ARCH consortium is structured to tackle antibiotic resistance challenges in both community and hospital environments. The ARCH studies, supported by the Centers for Disease Control and Prevention, endeavor to evaluate the extent of antibiotic resistance by analyzing the prevalence of colonization within community and hospital populations, and to assess factors that elevate colonization risk. This supplement's seven articles contain the results stemming from these initial research studies. Future research, dedicated to pinpointing and evaluating preventive strategies, will be indispensable in combating the dissemination of antibiotic resistance and its effect on populations; these studies' outcomes address crucial issues surrounding antibiotic resistance epidemiology.
The transmission of carbapenem-resistant Enterobacterales (CRE) could be exacerbated by the crowded state of emergency departments (EDs).
In the emergency department (ED) of a Brazilian tertiary academic hospital, a two-phase (baseline and intervention) quasi-experimental study was undertaken to assess the influence of an intervention on CRE colonization acquisition rates and to delineate risk factors associated with colonization. During both stages of the study, rapid molecular testing (blaKPC, blaNDM, blaOXA48, blaOXA23, and blaIMP) was employed alongside standard microbiological culturing during universal screening. Initially, neither screening test result was documented, prompting contact precautions (CP) due to prior colonization or infection with multidrug-resistant organisms.
