Sequential Blood Collection from Inferior Vena Cava Followed by Portal Vein to Evaluate Gut Microbial Metabolites in Mice.

Gut microbial products are known to act both locally within the intestine and get absorbed into circulation, where their effects can extend to numerous distant organ systems. Short-chain fatty acids (SCFA) are one class of metabolites produced by gut microbes during the fermentation of indigestible dietary fiber. They are now recognized as important contributors to how the gut microbiome influences extra-intestinal organ systems via the gut-lung, gut-brain, and other gut-organ axes throughout the host.

The National Clinical Care Commission Report to Congress: Background, Methods, and Foundational Recommendations.

Since the first Federal Commission on Diabetes issued its report in 1975, the diabetes epidemic in the U.S. has accelerated, and efforts to translate advances in diabetes treatment into routine clinical practice have stalled.

The National Clinical Care Commission Report to Congress: Recommendations to Better Leverage Federal Policies and Programs to Prevent and Control Diabetes.

The National Clinical Care Commission (NCCC) was established by Congress to make recommendations to leverage federal policies and programs to more effectively prevent and treat diabetes and its complications. The NCCC developed a guiding framework that incorporated elements of the Socioecological and Chronic Care Models. It surveyed federal agencies and conducted follow-up meetings with representatives from 10 health-related and 11 non-health-related federal agencies.

The National Clinical Care Commission Report to Congress: Summary and Next Steps.

The U.S. is experiencing an epidemic of type 2 diabetes.

Pharmacokinetics of Ceftazidime-Avibactam in Combination with Aztreonam (COMBINE) in a Phase 1, Open-Label Study of Healthy Adults.

Scant pharmacokinetic (PK) data are available on ceftazidime-avibactam (CZA) and aztreonam (ATM) in combination, and it is unknown if CZA-ATM exacerbates alanine aminotransferase (ALT)/aspartate aminotransferase (AST) elevations relative to ATM alone. This phase 1 study sought to describe the PK of CZA-ATM and assess the associations between ATM exposures and ALT/AST elevations. Subjects ( = 48) were assigned to one of six cohorts (intermittent infusion [II] CZA, continuous infusion [CI] CZA, II ATM, CI ATM [8 g/daily], II CZA with II ATM [6 g/daily], and II CZA with II ATM [8 g/daily]), and study product(s) were administered for 7 days.

Safety of Ceftazidime-Avibactam in Combination with Aztreonam (COMBINE) in a Phase I, Open-Label Study in Healthy Adult Volunteers.

This phase I study evaluated the safety of the optimal ceftazidime-avibactam (CZA) with aztreonam (ATM) regimens identified in hollow fiber infection models of MBL-producing Enterobacterales. Eligible healthy subjects aged 18 to 45 years were assigned to one of six cohorts: 2.5 g CZA over 2 h every 8 h (approved dose), CZA continuous infusion (CI) (7.

A Mouse Model of Orotracheal Intubation and Ventilated Lung Ischemia Reperfusion Surgery.

Ischemia reperfusion (IR) injury frequently results from processes that involve a transient period of interrupted blood flow. In the lung, isolated IR permits the experimental study of this specific process with continued alveolar ventilation, thereby avoiding the compounding injurious processes of hypoxia and atelectasis. In the clinical context, lung ischemia reperfusion injury (also known as lung IRI or LIRI) is caused by numerous processes, including but not limited to pulmonary embolism, resuscitated hemorrhagic trauma, and lung transplantation.

Management of opioid use disorder, opioid withdrawal, and opioid overdose prevention in hospitalized adults: A systematic review of existing guidelines.

Background: Hospitalizations related to the consequences of opioid use are rising. National guidelines directing in-hospital opioid use disorder (OUD) management do not exist. OUD treatment guidelines intended for other treatment settings could inform in-hospital OUD management.

Functional Transcriptomic Studies of Immune Responses and Endotoxin Tolerance in Early Human Sepsis.

Background: Limited studies have functionally evaluated the heterogeneity in early ex vivo immune responses during sepsis. Our aim was to characterize early sepsis ex vivo functional immune response heterogeneity by studying whole blood endotoxin responses and derive a transcriptional metric of ex vivo endotoxin response.

Methods: Blood collected within 24 h of hospital presentation from 40 septic patients was divided into two fractions and incubated with media (unstimulated) or endotoxin.

Don't mess with the pancreas! A multicenter analysis of the management of low-grade pancreatic injuries.

Introduction: Current guidelines recommend nonoperative management (NOM) of low-grade (American Association for the Surgery of Trauma-Organ Injury Scale Grade I-II) pancreatic injuries (LGPIs), and drainage rather than resection for those undergoing operative management, but they are based on low-quality evidence. The purpose of this study was to review the contemporary management and outcomes of LGPIs and identify risk factors for morbidity.

Methods: Multicenter retrospective review of diagnosis, management, and outcomes of adult pancreatic injuries from 2010 to 2018.

From Diversity and Inclusion to Antiracism in Medical Training Institutions.

The glaring racial inequities in the impact of the COVID-19 pandemic and the devastating loss of Black lives at the hands of police and racist vigilantes have catalyzed a global reckoning about deeply rooted systemic racism in society. Many medical training institutions in the United States have participated in this discourse by denouncing racism, expressing solidarity with people of color, and reexamining their diversity and inclusion efforts. Yet, the stagnant progress in recruiting, retaining, and supporting racial/ethnic minority trainees and faculty at medical training institutions is well documented and reflects unaddressed systemic racism along the academic pipeline.

Time to ACT: launching an Addiction Care Team (ACT) in an urban safety-net health system.

Across the USA, morbidity and mortality from substance use are rising as reflected by increases in acute care hospitalisations for substance use complications and substance-related deaths. Patients with substance use disorders (SUD) have long and costly hospitalisations and higher readmission rates compared to those without SUD. Hospitalisation presents an opportunity to diagnose and treat individuals with SUD and connect them to ongoing care.

Determining the optimal dosing of a novel combination regimen of ceftazidime/avibactam with aztreonam against NDM-1-producing Enterobacteriaceae using a hollow-fibre infection model.

Background: MBL-producing strains of Enterobacteriaceae are a major public health concern. We sought to define optimal combination regimens of ceftazidime/avibactam with aztreonam in a hollow-fibre infection model (HFIM) of MBL-producing strains of Escherichia coli and Klebsiella pneumoniae.

Methods: E.

MicroRNA biomarkers associated with type 1 myocardial infarction in HIV-positive individuals.

Objective: Individuals with HIV suffer a higher burden of cardiovascular diseases. Traditional cardiovascular risk scores consistently underestimate cardiovascular risk in this population. Subsets of microRNAs (miRNAs) are differentially expressed among individuals with cardiovascular disease and individuals infected with HIV.

CROI 2017: Complications and Comorbidities of HIV Disease and Its Treatment.

Complications of HIV disease remained a major focus at the 2017 Conference on Retroviruses and Opportunistic Infections (CROI), and included studies focused on noncommunicable chronic diseases (eg, cardiovascular disease, obesity, bone disease, and malignancies) and opportunistic infections (Mycobacterium tuberculosis and cryptococcosis). Progress in identifying predictors of specific complications as well as interventions for the prevention and treatment of these comorbidities are summarized below.

Improvement of drug identification in urine by LC-QqTOF using a probability-based library search algorithm.

A common method for identifying an unknown compound involves acquiring its mass spectrum and then comparing that spectrum against a spectral database, or library. Accurate comparison and identification is dependent on the quality of both the library and the test spectrum, but also the search algorithm used. Here, we describe a redesigned probability-based library search algorithm (ProLS) and compare its performance against two predicate algorithms, AMDIS from NIST (NIST) and LibraryView/MasterView (LV/MV), on human urine samples containing drugs of interest that were analyzed by quadrupole-time of flight (QqTOF) mass spectrometry.

Body-Weight Fluctuations and Outcomes in Coronary Disease.

Background: Body-weight fluctuation is a risk factor for death and coronary events in patients without cardiovascular disease. It is not known whether variability in body weight affects outcomes in patients with coronary artery disease.

Methods: We determined intraindividual fluctuations in body weight from baseline weight and follow-up visits and performed a post hoc analysis of the Treating to New Targets trial, which involved assessment of the efficacy and safety of lowering low-density lipoprotein cholesterol levels with atorvastatin.
