There has been interest in administering cefepime, a β-lactam antibiotic, via intravenous push (IVP) as a means to improve time to first-dose antibiotic and reduce cost; however, the downstream impacts on antibiotic exposure and pharmacodynamic efficacy need to be further evaluated.

This study used a population pharmacokinetic model for cefepime and simulated exposures to predict the pharmacodynamic (PD) effect for cefepime regimens administered via IVP or 30-minute intermittent infusion in adults with different renal functions. FDA-approved adult dosages of 1-2 g every 8 or 12 hours were compared. This study aimed to compare the absolute difference in pharmacodynamic probability of target attainment (PTA) between IVP and intermittent infusion, defined as free cefepime concentrations above organism MIC for ≥ 70% of the time.

At MICs of 0.25-0.5 mg/L, absolute differences in PTA were observed, with a reduction as great as 2.3% (89% to 86.7% for 30-minute intermittent infusion and IVP, respectively). At MICs of 1-4 mg/L, 30-minute intermittent infusion and IVP exhibited PTA differences as great as 5.4%, from 89.4% to 84%, respectively. At MICs of ≥8mg/L, similar absolute differences existed; however, no regimen achieved a PTA >70%. Across renal function strata of 60, 100 and 140 mL/minute (within the same dosing group and MICs), better renal function lowered PTAs.

Simulations demonstrated that IVP cefepime resulted in lower PTAs than traditional intermittent infusion among a subset of elevated MICs. Clinicians should exercise caution in IVP strategy, as unintended clinical consequences are possible.

Obstructive meibomian gland dysfunction (MGD) can be refractory to medical therapy. Intraductal meibomian gland (MG) probing may offer a potential therapeutic approach for these patients, but no randomized trials have been conducted to date.

To assess clinical changes after intraductal MG probing for patients with refractory obstructive meibomian gland dysfunction.

Randomized, double-masked, sham-controlled clinical trial.

Single-center, tertiary referral center.

42 patients with refractory obstructive MGD associated with lid tenderness.

Enrolled patients received one of the following treatments 1) MG probing plus post-procedural topical sulfacetamide/prednisolone ointment (Blephamide®), 2) MG probing plus post-procedural lubricating ointment (GenTeal), or 3) sham probing plus GenTeal ointment. The probing was performed on the upper lids of both eyes.

Primary outcome measures were symptoms as measured by Ocular Surface Disease Index (OSDI) and Symptom Assessment iN Dry Eye (SANDE), as well as tehamide® results in a significant improvement in symptoms in patients with refractory obstructive MGD without any significant effect on clinical signs. Larger studies are warranted to determine the efficacy of MG probing.

Magnetic resonance imaging proton density fat fraction (MRI-PDFF) offers promise as a non-invasive biomarker of treatment response in early-phase nonalcoholic steatohepatitis (NASH) trials. We performed a systematic review to quantify the association between a ≥ 30% reduction in MRI-PDFF and histologic response in NASH.

We searched the Cochrane Library, Embase, Medline and trial registries through May 2020 for early-phase clinical trials that incorporated MRI-PDFF and examined histologic response following intervention in adults with NASH. Subjects were classified as MRI-PDFF responders (relative decline in liver fat ≥30%) or non-responders (relative decline in liver fat <30%). MRI-PDFF responders versus non-responders were compared. Primary outcome was histologic response defined as a 2-point improvement in NAFLD Activity Score with at least 1-point improvement in lobular inflammation or ballooning. Secondary outcome was NASH resolution. Proportions and random effects odds ratios (OR) with correspondise in early-phase NASH clinical trials and provide helpful data for sample-size estimation for histology-based assessment.
To our knowledge, the interaction between alcohol consumption and PNPLA3 genotype on hepatic steatosis has not been explored in a representative sample. Autophagy activator To examine the interaction between alcohol consumption and PNPLA3 genotype on hepatic steatosis in the US adult population.

Cross-sectional study of 4,674 adult participants of the Third National Health and Nutrition Examination Survey, Phase 2 (1991-1994) with data on PNPLA3 genotype, self-reported alcohol consumption, ultrasound-defined hepatic steatosis and socio-demographic characteristics.

In 1991-1994 in the U.S. population, the weighted allele frequency of the G (risk) allele of the rs738409 at PNPLA3 was 25.4%. We confirmed both a J shaped association between alcohol consumption and hepatic steatosis among those with the CC genotype of PNPLA3, and a higher prevalence of hepatic steatosis among those with PNPLA3 gene G variant. We found evidence of an interaction of PNPLA3 G allele presence on the association between moderate alcohol consumption and hepatic steatosis on both the multiplicative (relative prevalence ratio [RPR]=1.95, 95% confidence interval [CI] 1.04-3.65) and additive scales (relative excess risk due to interaction=0.49, 95% CI 0.13-0.85). Compared to never drinkers, moderate alcohol drinking was associated with a 48% decreased risk of hepatic steatosis only among those without PNPLA3 G allele (PR=0.52, 95% CI 0.26-1.05), with no association among those with at least one copy of the PNPLA3 G allele (PR=1.02, 95% CI 0.68-1.54).

Our results suggest that a highly common and strong genetic susceptibility to liver disease is modifiable by the level of alcohol consumption. Keeping alcohol consumption low may offset genetic predisposition to liver disease.
