001). There was also a significant difference between groups for animal age (p= 0.036) but not for breed (p= 0.573) or induction agent (p= 0.239).

and clinical relevance Veterinary students take longer to achieve successful endotracheal intubation of anaesthetized healthy dogs compared with qualified veterinary surgeons. To mitigate any additional risk of dogs developing hypoxaemia, it is recommended that a 55 second time limit is set after which the supervisor intervenes and takes over the intubation procedure. Preoxygenation may be used as an additional mitigation strategy.

To evaluate the systemic cardiovascular effects of dose escalating administration of norepinephrine in healthy dogs anesthetized with isoflurane.

Experimental study.

A total of six adult laboratory Beagle dogs, 10.5 (9.2-12.0) kg [median (range)].

Each dog was anesthetized with isoflurane at an end-tidal concentration of 1.7%, mechanically ventilated and administered a continuous rate infusion of rocuronium (0.5 mg kg

hour

). Each dog was administered incremental dose rates of norepinephrine (0.05, 0.125, 0.25, 0.5, 1.0 and 2.0 μg kg

minute

), and each dose was infused for 15 minutes. Cardiovascular variables were recorded before administration and at the end of each infusion period.

Norepinephrine infusion increased mean arterial pressure (MAP), cardiac output (CO) and oxygen delivery in a dose-dependent manner. Systemic vascular resistance did not significantly change during the experiment. Stroke volume increased at the lower dose rates and heart rate increased at the higher dose rates. Oxygen consumption and lactate concentrations did not significantly change during infusions.

In dogs anesthetized with isoflurane, norepinephrine increased MAP by increasing the CO. CO increased with a change in stroke volume at lower dose rates of norepinephrine. At higher dosage, heart rate also contributed to an increase in CO. Norepinephrine did not cause excessive vasoconstriction that interfered with the CO during this study.

Norepinephrine can be useful for treating hypotension in dogs anesthetized with isoflurane.

Using a recently developed light-sheet microscope, Geoghegan et al. investigated invasion with unprecedented temporal resolution. Their spectacular footage revealed roles for host cell cholesterol and pore formation at the parasite-host cell interface.

To evaluate the safety and efficacy of lotilaner ophthalmic solution, 0.25% for the treatment of blepharitis due to Demodex infestation compared to vehicle control.

In this phase II, randomized, controlled, double-masked clinical trial, 60 eligible participants with Demodex blepharitis were randomly assigned in a 11 ratio to receive either topical lotilaner ophthalmic solution, 0.25% (Tarsus Pharmaceuticals, Inc., Irvine, CA) (study group) or the vehicle without lotilaner (control group) bilaterally twice a day for 28days. Participants were followed at Days 7, 14, 28, 60 and 90. The efficacy parameters were change in collarette grade and Demodex density at Day 28. Safety parameters were adverse events, changes in corrected distance visual acuity (CDVA), intraocular pressure (IOP) and slit-lamp biomicroscopy.

The study group showed a statistically significant decrease in collarette grade compared to the control group beginning at Day 14 (p=0.003) in the upper eyelid and at Day 28 (p=0.003) in the lower eyelid. Decreases in both lids were maintained through Day 90 (p<0.001). At Day 28, mite eradication was achieved in 66.7% and 25.9% of eyes in the study and control group (p=0.005); at Day 90, these proportions were 68.2% and 18.5% (p=0.001), respectively. No serious adverse events or clinically significant changes in CDVA and IOP were observed.

For Demodex blepharitis, treatment with lotilaner ophthalmic solution, 0.25% for 4weeks is safe and effective. The improvement in collarette grade and mite density observed during the treatment period persisted for at least two months following treatment cessation.

Few reports have evaluated prognostic modelling studies of tools used for surgical decision-making. This systematic review aimed to describe and critically appraise studies that have developed or validated multivariable prognostic models for post-operative liver decompensation following partial hepatectomy.

This study was designed using the CHARMS checklist. Following a comprehensive literature search, two reviewers independently screened candidate references for inclusion and abstracted relevant study details. Qualitative assessment was performed using the PROBAST tool.

We identified 36 prognostic modelling studies; 25 focused on development only, 3 developed and validated models, and 8 validated pre-existing models. None compared routine use of a prognostic model against standard clinical practice. Most studies used single-institution, retrospective cohort designs, conducted in Eastern populations. In total, 15 different outcome definitions for post-operative liver decompensation events were used. Statistical concerns surrounding model overfitting, performance assessment, and internal validation led to high risk of bias for all studies.

Current prognostic models for post-operative liver decompensation following partial hepatectomy may not be valid for routine clinical use due to design and methodologic concerns. Landmark resources and reporting guidelines such as the TRIPOD statement may assist researchers, and additionally, model impact assessment studies represent opportunities for future research.

The pharmaceutical industry is forced to contain costs by outsourcing drug testing to commercial contract research organizations (CROs). This ensures the performance of clinical trials by experienced employees who must competently and skillfully exercise due care and diligence. Skilled talent for demanding CRO's is scarce, expensive and hard to retain. Evidence from empirical examinations in the CRO industry will be valuable for decision-makers. The lack of employee engagement and the neglect of employee well-being has financially harmful implications for industries with high job demands.

This study investigated the relationship between supervisor support, the satisfaction of self-determination needs and engagement at work, emotional exhaustion and intention to leave in a CRO.

A quantitative, cross-sectional approach was employed. Participants comprised a convenience sample of 260 CRO-employed males and females 18 years and older with different education and tenure levels. Structural equation modelling eeds should not be neglected in organizations with high job demands where talent retention is critical.

The study highlights the importance of the relationship between supervisor support, satisfaction of self-determination needs, employee engagement and well-being in a demanding organization. Although supervisor support is associated with improved work engagement and employee well-being, the improvement of satisfaction of self-determination needs should not be neglected in organizations with high job demands where talent retention is critical.

The incidence of carbapenem-resistant Klebsiella pneumoniae (CRKP) has rapidly increased. This study aimed to assess the effect of Coptis chinensis and its compounds on the minimal inhibitory concentrations (MICs) of eight antibiotics against CRKP.

Cell cultures were used to investigate the effects of C. chinensis and its compounds on the MICs of eight antibiotics against CRKP. The MICs for antibiotics alone and antibiotics with C. chinensis or compounds were measured and compared. Furthermore, the effects of C. chinensis on cell membrane injury and intracellular adenosine triphosphate (ATP) CRKP concentration were also measured. The Mann-Whitney rank-sum test was used to analyze the differences between means.

C. chinensis exhibits a notable MIC bacteriostatic effect at 5mg/mL on CRKP. A significant MIC reduction against CRKP exists when C. chinensis was added to colistin and colistin-containing two-antibiotic combinations. Moreover, C. chinensis could damage cell membrane integrity and decrease intracellular ATP concentration in CRKP. Thus, C. chinensis exhibits antimicrobial activity superiority with colistin against CRKP. Furthermore, the effects of identified compounds in C. chinensis on the MICs of colistin, four-to eight-, two-to four-, and one-to two-fold reductions were found in ferulic acid, magnoflorine, and jatrorrhizine hydrochloride, respectively. Among these compounds, ferulic acid destroys membrane integrity and decreases intracellular ATP concentration.

C. chinensis and ferulic acid can potentiate the antimicrobial activity of colistin and may represent a promising component of combination therapy against CRKP infections in a clinical setting.

C. Rapamycin chinensis and ferulic acid can potentiate the antimicrobial activity of colistin and may represent a promising component of combination therapy against CRKP infections in a clinical setting.Atherosclerosis is the commonest cause of death in Australia. Cardiovascular (CV) risk calculators have an important role in preventative cardiology, although they are are strongly age-dependent and designed to identify individuals at high risk of an imminent event. The imprecision around "intermediate" or "low" risk generates therapeutic uncertainty, and a significant proportion of patients presenting with myocardial infarction come from these groups, often with no warning. This highlights a conundrum "Low" risk does not mean "no" risk. A fresh approach may be required to address the clinical conundrum around CV preventative approaches in non-high-risk individuals. While probabilistic calculators do not measure atherosclerosis, calculation of Coronary Artery Calcium (CAC) scores by low-dose computed tomography (CT) can provide a snapshot of atherosclerotic burden. In intermediate-risk individuals, CAC is well-established as an aid to CV risk prediction. Although CAC scoring in low-risk asymptomatic people may be considered controversial, CAC has emerged as the single best predictor of CV events in asymptomatic individuals, independent of traditional risk factor calculators.
