: Three-year Mortality Following Prescription of Multidrug Antibiotic Treatment for Pulmonary Disease in United States Medicare Beneficiaries With Bronchiectasis.

Background/aims: Although increased mortality has been reported among people with pulmonary disease (MAC-PD), data are limited on survival associated with various antibiotic regimens used to treat MAC-PD. We conducted a comparative analysis of 3-year mortality in Medicare beneficiaries with bronchiectasis using various MAC-PD regimens.

Methods: We included Medicare beneficiaries aged ≥65 years with bronchiectasis (01/2006-12/2014).

Examining the impact of the COVID-19 pandemic on hospital-associated infection.

Objective: To evaluate the impact of changes in the size and characteristics of the hospitalized patient population during the COVID-19 pandemic on the incidence of hospital-associated infection (HA-CDI).

Design: Interrupted time-series analysis.

Setting: A 576-bed academic medical center in Portland, Oregon.

Validation of electronic health record data to identify hospital-associated infections for retrospective research.

infection (CDI) research relies upon accurate identification of cases when using electronic health record (EHR) data. We developed and validated a multi-component algorithm to identify hospital-associated CDI using EHR data and determined that the tandem of CDI-specific treatment and laboratory testing has 97% accuracy in identifying HA-CDI cases.

Management of isolated native tricuspid valve infective endocarditis by a multidisciplinary program: a single-center retrospective cohort study.

Background: Isolated native tricuspid valve infective endocarditis remains a challenging disease to treat given the large number of patients with substance use disorder. There is limited data on the optimal treatment strategy and the impact of a multidisciplinary endocarditis program on outcomes for this population.

Objectives: To assess the clinical outcomes associated with management of native tricuspid valve infective endocarditis by a multidisciplinary team.

Influence of Antibiotic Exposure Intensity on the Risk of Clostridioides difficile Infection.

Background: Antibiotics are a strong risk factor for Clostridioides difficile infection (CDI), and CDI incidence is often measured as an important outcome metric for antimicrobial stewardship interventions aiming to reduce antibiotic use. However, risk of CDI from antibiotics varies by agent and dependent on the intensity (ie, spectrum and duration) of antibiotic therapy. Thus, the impact of stewardship interventions on CDI incidence is variable, and understanding this risk requires a more granular measure of intensity of therapy than traditionally used measures like days of therapy (DOT).

Shared Decision-Making for Partial Oral Antibiotic Treatment of Infective Endocarditis: A Case Series.

Although literature has demonstrated the noninferiority of oral antibiotics in the treatment of infectious endocarditis, widespread adoption of this practice has yet to occur in the United States. We report on 32 patients with infectious endocarditis treated by a multidisciplinary endocarditis team and a standardized approach to partial oral antibiotic therapy with a high rate of clinical success.

Dalba Got Back? Use of Dalbavancin for the Treatment of Vertebral Osteomyelitis.

Data evaluating dalbavancin use for vertebral osteomyelitis remain limited. In our retrospective cohort, 29 of 34 (85.3%) patients completed their dalbavancin course.

Use of electronic health record data to identify hospital-associated infections: a validation study.

Background: Clinical research focused on the burden and impact of infection (CDI) often relies upon accurate identification of cases using existing health record data. Use of diagnosis codes alone can lead to misclassification of cases. Our goal was to develop and validate a multi-component algorithm to identify hospital-associated CDI (HA-CDI) cases using electronic health record (EHR) data.

More than urns: A multi-method pipeline for analyzing cremation burials.

Burial rites of archaeological populations are frequently interpreted based on cremated remains of the human body and the urn they were deposited in. In comparison to inhumations, information about the deceased is much more limited and dependent on fragmentation, selection of body regions, taphonomic processes, and excavation techniques. So far, little attention has been paid to the context in which urns are buried.

The hidden cost of dalbavancin: OPAT RN time required in coordination for persons who use drugs.

Background: Serious infections in persons who use drugs (PWUD) are rising. Dalbavancin, due to its extended half-life, offers an alternative treatment for patients in whom standard of care antibiotics are not feasible or practical, allowing for reduced hospital days and the avoidance of central line placement or the use of complex oral regimens.

Objectives: We aim to describe the time and effort required for coordination of dalbavancin courses by outpatient registered nurses (RNs) and other outpatient parenteral antimicrobial therapy (OPAT) staff.

Open-Label Trial of Amikacin Liposome Inhalation Suspension in Mycobacterium abscessus Lung Disease.

Background: Mycobacterium abscessus is the second most common nontuberculous mycobacterium respiratory pathogen and shows in vitro resistance to nearly all oral antimicrobials. M abscessus treatment success is low in the presence of macrolide resistance.

Research Question: Does treatment with amikacin liposome inhalation suspension (ALIS) improve culture conversion in patients with M abscessus pulmonary disease who are treatment naive or who have treatment-refractory disease?

Study Design And Methods: In an open-label protocol, patients were given ALIS (590 mg) added to background multidrug therapy for 12 months.

Spatial and temporal trends in δZn and Pb/Pb isotope ratios along a rural transect downwind from the Upper Silesian industrial area: Role of legacy vs. present-day pollution.

Transect sampling is an under-exploited tool in isotope studies of atmospheric pollution. Few studies have combined Zn and Pb isotope ratios to investigate whether atmospheric pollution at a receptor site is dominated by a different anthropogenic source of each of these toxic elements. It has been also unclear whether pollution abatement strategies in Central Europe have already resulted in regionally well-mixed background isotope signature of atmospheric Zn and Pb.

Effects of a point source of phosphorus on the arsenic mobility and transport in a small fluvial system.

One of the leading causes of As release from streambed sediments into freshwater systems is competition with phosphate. Among important sources of P to the fluvial ecosystems are wastewater treatment plants (WWTP), estimated to account for 25-45% of all P in surface waters. In this paper, long-term effects of discharged phosphorus from a small WWTP on the arsenic mobility were studied in an As-enriched fluvial system (approx.

Influence of Probiotic Strains , , and on the Health Status and Weight Gain of Calves, and the Utilization of Nitrogenous Compounds.

The aim of this study was to monitor the effect of Bifidobacterium bifidum (BB) and the combination of Lactobacillus sporogenes, Enterococcus faecium, and Bifidobacterium bifidum (LEB) on the health status and weight gain of calves, and the utilisation of nitrogenous substances. The experiment was performed in the period from April 2020 to September 2020. A total of 90 Holstein heifers, which were one to 56 days old, were used as experimental animals.

Expanding the Team: Optimizing the Multidisciplinary Management of Drug Use-Associated Infective Endocarditis.

Amidst a substance use epidemic, hospitalizations and valve surgeries related to drug use-associated infective endocarditis (DU-IE) rose substantially in the last decade. Rates of reoperation and mortality remain high, yet in many hospitals patients are not offered valve surgery or evidence-based addiction treatment. A multidisciplinary team approach can improve outcomes in patients with infective endocarditis; however, the breadth of expertise that should be incorporated into this team is inadequately conceptualized.

Archaeometric perspective on the emergence of brass north of the Alps around the turn of the Era.

Ancient brass (aurichalcum) was a valued commodity in the Antiquity, notably because of its gold-like appearance. After mastering brass fabrication using the cementation procedure in the first century BC in the Mediterranean, this material became widely used by the Romans for coins, jewellery and other artefacts. Because of its visual qualities, it is believed that since this period, brass played an important role in diplomatic and economic contacts with indigenous communities, notably Celtic and Germanic tribes north of Danube and west of Rhine.

Correction: Poly(acrylic acid)-mediated synthesis of cerium oxide nanoparticles with variable oxidation states and their effect on regulating the intracellular ROS level.

Correction for 'Poly(acrylic acid)-mediated synthesis of cerium oxide nanoparticles with variable oxidation states and their effect on regulating the intracellular ROS level' by Xiaohui Ju , , 2021, , 7386-7400, DOI: 10.1039/D1TB00706H.

Poly(acrylic acid)-mediated synthesis of cerium oxide nanoparticles with variable oxidation states and their effect on regulating the intracellular ROS level.

Cerium oxide nanoparticles (CeNPs) possess multiple redox enzyme mimetic activities in scavenging reactive oxygen species (ROS) as a potential biomedicine. These enzymatic activities of CeNPs are closely related to their surface oxidation state. Here we have reported a synthetic method to modify CeNPs' surface oxidation state by changing the conformation of the poly(acrylic acid) (PAA) polymers adsorbed onto the CeNP surface.

"OPTIONS-DC", a feasible discharge planning conference to expand infection treatment options for people with substance use disorder.

Background: Serious bacterial infections associated with substance use often result in long hospitalizations, premature discharges, and high costs. Out-of-hospital treatment options in people with substance use disorder (SUD) are often limited.

Methods: We describe a novel multidisciplinary and interprofessional care conference, "OPTIONS-DC," to identify treatment options agreeable to both patients and providers using the frameworks of harm reduction and patient-centered care.

Reductions in vancomycin and meropenem following the implementation of a febrile neutropenia management algorithm in hospitalized adults: An interrupted time series analysis.

Objective: To evaluate broad-spectrum intravenous antibiotic use before and after the implementation of a revised febrile neutropenia management algorithm in a population of adults with hematologic malignancies.

Design: Quasi-experimental study.

Setting And Population: Patients admitted between 2014 and 2018 to the Adult Malignant Hematology service of an acute-care hospital in the United States.

Population-based trends in hospitalizations due to injection drug use-related serious bacterial infections, Oregon, 2008 to 2018.

Background: Injection drug use has far-reaching social, economic, and health consequences. Serious bacterial infections, including skin/soft tissue infections, osteomyelitis, bacteremia, and endocarditis, are particularly morbid and mortal consequences of injection drug use.

Methods: We conducted a population-based retrospective cohort analysis of hospitalizations among patients with a diagnosis code for substance use and a serious bacterial infection during the same hospital admission using Oregon Hospital Discharge Data.

Top Questions in the Diagnosis and Treatment of Pulmonary Disease.

disease is particularly challenging to treat, given the intrinsic drug resistance of this species and the limited data on which recommendations are based, resulting in a greater reliance on expert opinion. We address several commonly encountered questions and management considerations regarding pulmonary disease, including the role of subspecies identification, diagnostic criteria for determining disease, interpretation of drug susceptibility test results, approach to therapy including the need for parenteral antibiotics and the role for new and repurposed drugs, and the use of adjunctive strategies such as airway clearance and surgical resection.
