Using murine models of infection, we previously reported the potent in vivo activity of carbapenems against MBL-producing Enterobacterales despite the observed resistance in vitro. In the current study, we examined the in vivo activity of a cefepime human-simulated regimen against MBL-producing Enterobacterales in a murine thigh infection model.

A population of clinical isolates and isogenic engineered MBL-producing Enterobacterales transformants expressing MBLs but no detectable cefepime-hydrolysing serine β-lactamases were utilized. KPC-producing isolates were included as positive controls. Cefepime, piperacillin/tazobactam and meropenem MICs were determined using broth microdilution in conventional CAMHB and EDTA-supplemented (zinc-limited) broth. In vivo efficacy of a cefepime human-simulated regimen (2 g q8h as a 2 h infusion) was determined in the neutropenic murine thigh infection model against the test strains. Efficacy was measured as the change in log10 cfu/thigh at 24 h compared with 0 h controvironment, in which zinc concentrations are low.
Total nucleated cell (TNC) count and differential are used to classify joint effusions as inflammatory or noninflammatory. Further diagnostic evaluation and management is contingent on this classification. TNC count can be measured by automated analyzers or by manual assessment using a hemocytometer. Studies have raised concerns regarding the accuracy of TNC counts measured by automated instruments, particularly in the setting of joint arthroplasty. The objective of this study was to determine whether metallosis, a complication of total hip arthroplasty in which metal debris accumulates in periprosthetic tissues and synovial fluid, is associated with inaccurate TNC counts in synovial fluid.

We compared the accuracy of cell counts measured by the Sysmex XN-1000 and Beckman Coulter Iris iQ200 with the gold standard of manual assessment using a hemocytometer in synovial fluid from patients with suspected metallosis and in fluid obtained from controls from patients with native joints and a history of arthroplasty for other indications.

TNC counts produced by automated analyzers were associated with increased levels of discordance (relative to manual counts) in patients with metallosis. Metallosis was not associated with increased levels of discordance for RBC counts or WBC differentials. The Sysmex XN flagged all but 1 metallosis sample for manual verification of the results.

Automated methods are generally reliable for analysis of synovial fluid. TNC counts can be inaccurate in the context of metallosis following total hip arthroplasty. Laboratories should correlate automated cell counts with a microscopic assessment of the specimen, as recommended by instrument manufacturers.

Greater neighborhood co-ethnic density (living in proximity with people sharing an ethnicity) and being foreign-born each can protect against risky drinking, but little is known about whether these two factors interact. Using a representative sample of Latinos and Asians from California, USA, we investigate main and interactive effects of neighborhood co-ethnic density and nativity status in relation to heavy episodic drinking (HED).

This study uses the California Health Interview Survey (N=30,203) linked with neighborhood data to investigate associations of co-ethnic density and nativity status with HED. Co-ethnic density was based on matching each respondent's ethnicity to the proportion of residents of the corresponding group in their Census tract. Using weighted logistic regression, we first examined main effects of neighborhood co-ethnic density and respondent nativity status on HED. Next, we assessed the interaction of co-ethnic density and nativity status. Finally, we estimated nativity-stratified models to investigate variation in effects of co-ethnic density.

Co-ethnic density was not associated with HED for the full sample, but US-born nativity status was associated with increased odds of past-year HED. The interaction model showed co-ethnic density and nativity had synergistic effects, whereby greater levels of neighborhood co-ethnic density buffered risk associated with being US-born. Further, greater neighborhood co-ethnic density was associated with reduced odds of HED for US-born respondents, but it was not associated with HED for foreign-born respondents.

Protective effects of high neighborhood co-ethnic density on HED are stronger for US-born than for foreign-born Latinos and Asians in California.

Alcohol intake is one of the factors associated with the occurrence of osteonecrosis of the femoral head (ONFH), and its epidemiological information regarding alcohol intake depends on patients' self-reports. Therefore, we analysed the efficacy of laboratory tests as an objective diagnostic tool to indicate habitual drinking in patients with alcohol-associated ONFH.

This study included 109 consecutive patients diagnosed with ONFH who underwent primary hip surgery in our institution between 2010 and 2018. The patients were classified into group AL (alcohol-associated ONFH; n=26) and group NO (alcohol-unassociated ONFH; n=83), based on their self-reported information. Serum levels of gamma-glutamyl transferase (GGT), mean corpuscular volume (MCV), aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol and triglycerides were compared between both groups. The sensitivities and specificities with the optimal cut-off values for detecting alcohol-associated ONFH were compared among these markers.

The median serum levels of GGT, AST and ALT were significantly higher in the AL group than in the NO group. link2 The receiver operating characteristic curve analysis demonstrated an area under the curve of 0.795 for GGT, 0.731 for AST and 0.709 for ALT. The optimal cut-off level of GGT as a marker for alcohol-associated ONFH was 36.5units/L, with a sensitivity of 76% and specificity of 80%, and it was found to be the best marker among the other examined laboratory markers.

Serum GGT level is a useful laboratory marker with moderate accuracy that indicates habitual drinking in patients with alcohol-associated ONFH.

To use proton magnetic resonance spectroscopy (1HMRS) and diffusion weighted imaging (DWI) to identify ethanol in the brain directly after consumption, and examine changes in brain metabolite levels and brain microstructure relative to the duration of time following exposure to alcohol.

The study involved 44 male volunteers (18-55years). All brain changes were assessed in the frontal lobes, occipital lobes, basal ganglia and cerebellum, however the detailed analyses focused on the frontal lobes. All participants were examined four times, i.e. before and 0.5-hour, 1hour and 2hours after consumption of 150mL pure vodka (60g of ethanol).

The highest ethanol levels were identified between 0.5 and 1hour following alcohol intake. There were significant increases in the concentrations of lipids and lactates approximately one hour after alcohol consumption, and the concentration levels were found to normalise during the following two hours. Some statistically insignificant trends of changes were found for tCr, tCho, mI, GABA, Glc, Glx and tNAA. For the DWI and ADC (Apparent Diffusion Coefficient of water) values, the findings showed statistically insignificant decrease and increase, followed by a tendency towards normalisation. Similar associations in changes of metabolite concentrations and DWI and ADC values were found in the other locations investigated in the study.

A single dose of alcohol as used in this experiment produces increases in lipids and lactates in brain tissues that appear reversible.

This article is one of the 5 articles describing steps taken to enhance sterile compounding compliance at a large, multisite academic medical center. link3 This article focuses on the development of a comprehensive personnel training and assessment program for sterile compounding.

Increased regulatory oversight and the release of new United States Pharmacopeia chapters motivated the reenvisioning of the medical center's sterile compounding personnel training and assessment program. The main challenges facing any entity undertaking sterile compounding include identification of compounding staff, development of policies and procedures, and baseline and ongoing training including observational competency assessments and record keeping. These challenges are exacerbated by high work volumes and variation in compounding practices encountered within a large multisite institution. Our organization developed a team of specialized pharmacists and pharmacy technicians to implement and enforce changes promoting the safe pr as evidenced by the success of the described program in overecoming past challenges.
Post-transcriptional regulation via RNA-binding proteins plays a fundamental role in every organism, but the regulatory mechanisms lack important understanding. Nevertheless, they can be elucidated by cross-linking immunoprecipitation in combination with high-throughput sequencing (CLIP-Seq). CLIP-Seq answers questions about the functional role of an RNA-binding protein and its targets by determining binding sites on a nucleotide level and associated sequence and structural binding patterns. In recent years the amount of CLIP-Seq data skyrocketed, urging the need for an automatic data analysis that can deal with different experimental set-ups. However, noncanonical data, new protocols, and a huge variety of tools, especially for peak calling, made it difficult to define a standard.

CLIP-Explorer is a flexible and reproducible data analysis pipeline for iCLIP data that supports for the first time eCLIP, FLASH, and uvCLAP data. Individual steps like peak calling can be changed to adapt to different experimental settings. We validate CLIP-Explorer on eCLIP data, finding similar or nearly identical motifs for various proteins in comparison with other databases. In addition, we detect new sequence motifs for PTBP1 and U2AF2. Finally, we optimize the peak calling with 3 different peak callers on RBFOX2 data, discuss the difficulty of the peak-calling step, and give advice for different experimental set-ups.

CLIP-Explorer finally fills the demand for a flexible CLIP-Seq data analysis pipeline that is applicable to the up-to-date CLIP protocols. The article further shows the limitations of current peak-calling algorithms and the importance of a robust peak detection.
