Fentanyl and its analogs are potent synthetic opioids with a high potential for abuse and dependence. They have become major contributors to opioid deaths. This study aimed to determine whether the metabolites of fentanyl, alpha-methylfentanyl and beta-hydroxyfentanyl, excreted in the urine, can demonstrate historical drug exposure. Fentanyl is primarily metabolized via CYP3A4 into norfentanyl, although there is little research on its metabolism into alpha-methylfentanyl and beta-hydroxyfentanyl. We conducted in vitro experiments with human liver microsomes (HLM) and rat liver microsomes (RLM) to elucidate the major metabolic pathways of alpha-methylfentanyl and beta-hydroxyfentanyl using UHPLC coupled with mass spectrometry. The results showed that both alpha-methylfentanyl and beta-hydroxyfentanyl were predominantly metabolized into norfentanyl in HLM and RLM. Urine samples were collected at different intervals from 0 h to 72 h after intravenous administration of alpha-methylfentanyl and beta-hydroxyfentany drug testing, and monitoring drug abuse.

The number of patient handoffs has increased in recent years. In addition, technology has advanced in the medical field, leading to most providers carrying smartphones at work. Little is known about the effect of mobile devices and quality of patient handoffs. The objective of this study was to determine whether distraction affects the quality of sign-out among obstetrical providers.

A randomized, prospective study was conducted.

Hospital.

Obstetrical providers listened to a recorded sign-out vignette. Provider groups either were or were not exposed to a distraction while listening to the vignette. All providers had been told that they would be participating in a trial of two methods of sign-out, although in actuality they were all assigned to a single method. In the distraction arm, the participants were exposed to a 'distracting event' (a phone ring, which was answered by the proctor and followed by a brief conversation) that occurred midway through the vignette.

Providers answered a 14-question survey testing recall of facts included in the vignette. The results of each group were analyzed using Fisher's exact test and Student's t-test.

Eighty-eight providers were randomized, 44 in the distraction group and 44 in the non-distracted group. The average scores on the survey were similar between groups (11.0 and 10.8, P = 0.57). read more In addition, the average scores for questions that occurred after the distraction did not differ between the distracted and non-distracted groups (6.4 vs 6.2, P = 0.42).

We observed that a phone ring and brief response did not affect the obstetrical providers' recall of details of a standardized sign-out. More studies are warranted to determine if more frequent or longer distractions would change results.

Venous thromboembolism (VTE) is an important patient safety concern. VTE leads to significant mortality and morbidity and a burden on healthcare resources. Despite the widespread availability of evidence-based clinical practice guidelines on VTE prophylaxis, we found that only 50.9% of our patients were receiving appropriate prophylaxis. The purpose of this study was to evaluate the impact of automation of an adapted VTE prophylaxis CPG using a clinical decision support system (the VTE-CDSS) on VTE prevention among hospitalised adult patients.

A quasi-experimental study (pre- and post-implementation) was conducted at a large 900-bed tertiary teaching multi-specialty hospital in Riyadh, Saudi Arabia.

The 1809 adult patients in the study included 871 enrolled during the pre-implementation stage and 938 enrolled during the post-implementation stage.

Multi-faceted implementation interventions were utilised, including leadership engagement and support, quality and clinical champions, staff training and edutation strategies approach improved the compliance rate of risk assessment and the adherence to prophylaxis recommendations and substantially reduced the HA-VTE prevalence. A successful CDSS requires a set of critical components to ensure better user compliance and positive patient outcomes.

The fractional availability of CC Nav current has been implicated in regulation of action potential (AP) frequency and the occurrence of slow-wave burst firing. Here, through recordings of Nav current in rat CCs, primarily in adrenal medullary slices, we describe unique inactivation properties of CC Nav inactivation that help define AP firing rates in CCs. The key feature of CC Nav current is that recovery from inactivation, even following brief (5 ms) inactivation steps, exhibits two exponential components of similar amplitude. Various paired pulse protocols show that entry into the fast and slower recovery processes result from largely independent competing inactivation pathways, each of which occurs with similar onset times at depolarizing potentials. Over voltages from -120 to -80 mV, faster recovery varies from ∼3 to 30 ms, while slower recovery varies from ∼50 to 400 ms. With strong depolarization (above -10 mV), the relative entry into slow or fast recovery pathways is similar and independent of voltage. Trains of short depolarizations favor recovery from fast recovery pathways and result in cumulative increases in the slow recovery fraction. Dual-pathway fast inactivation, by promoting use-dependent accumulation in slow recovery pathways, dynamically regulates Nav availability. Consistent with this finding, repetitive AP clamp waveforms at 1-10 Hz frequencies reduce Nav availability 80-90%, depending on holding potential. These results indicate that there are two distinct pathways of fast inactivation, one leading to conventional fast recovery and the other to slower recovery, which together are well-suited to mediate use-dependent changes in Nav availability.
