Biliary complications are still a major cause for morbidity and mortality after liver transplantation (LT). Ischemia/reperfusion injury (IRI) leads to disruption of the biliary epithelium. We introduce a novel model to study the effect of IRI on human cholangiocytes using extrahepatic cholangiocyte organoids (ECOs).

Background: The opioid crisis has put an increasing strain on US states over the last two decades. In response, all states have passed legislation to implement a portfolio of policies to address the crisis. Although effects of some of these policies have been studied, research into factors associated with state policy adoption decisions has largely been lacking.
View Article and Find Full Text PDFProblem/condition: In 2017, a total of 70,237 persons in the United States died from a drug overdose, and 67.8% of these deaths involved an opioid. Historically, the opioid overdose epidemic in the United States has been closely associated with a parallel increase in opioid prescribing and with widespread misuse of these medications.
View Article and Find Full Text PDFBackground: Comprehensive mandatory use laws for prescription drug monitoring programs (PDMPs) have been implemented in a number of states to help address the opioid overdose epidemic. These laws may reduce opioid-related overdose deaths by increasing prescribers' use of PDMPs and reducing high-risk prescribing behaviors.
Methods: We used state PDMP data to examine the effect of these mandates on prescriber registration, use of the PDMP, and on prescription-based measures of patient risk in three states-Kentucky, Ohio, and West Virginia-that implemented mandates between 2010 and 2015.
Background: DATA 2000 enabled physicians with approved training to be waivered to prescribe buprenorphine for the treatment of opioid use disorders (OUD) for a limited number of patients. A rule change in 2016 increased the patient limit for certain buprenorphine waivered physicians from 100 to 275. This study examines the prescribing patterns of buprenorphine prescribers by waiver limit status (30- or 100-patient limit).
View Article and Find Full Text PDFBackground: Opioid overdose and other related harms are a major source of morbidity and mortality among US Veterans, in part due to high-risk opioid prescribing.
Objectives: We sought to determine whether having multiple sources of payment for opioids-as a marker for out-of-system access-is associated with risky opioid therapy among veterans.
Research Design: Cross-sectional study examining the association between multiple sources of payment and risky opioid therapy among all individuals with Veterans Health Administration (VHA) payment for opioid analgesic prescriptions in Kentucky during fiscal year 2014-2015.
Objective: State prescription drug monitoring programs (PDMPs) can help detect individuals with multiple provider episodes (MPEs; also referred to as doctor/pharmacy shopping), an indicator of prescription drug abuse and/or diversion. Although unsolicited reporting by PDMPs to prescribers of opioid analgesics is thought to be an important practice in reducing MPEs and the potential harm associated with them, evidence of its effectiveness is mixed. This exploratory research evaluates the impact of unsolicited reports sent by Massachusetts' PDMP to the prescribers of persons with MPEs.

This study examined associations between prescriber risk indicators developed as part of a public health surveillance project and medical board disciplinary actions against prescribers.
View Article and Find Full Text PDFBackground: The current US opioid epidemic is attributed to the large volume of prescribed opioids. This study analyzed the contribution of different medical specialties to overall opioids by evaluating the pill counts and morphine milligram equivalents (MMEs) of opioid prescriptions, stratified by provider specialty, and determined temporal trends.
Methods: This was an analysis of the Ohio prescription drug monitoring program database, which captures scheduled medication prescriptions filled in the state as well as prescriber specialty.
Problem/condition: Drug overdose is the leading cause of injury death in the United States. The death rate from drug overdose in the United States more than doubled during 1999-2013, from 6.0 per 100,000 population in 1999 to 13.
View Article and Find Full Text PDFPublic health authorities have described, with growing alarm, an unprecedented increase in morbidity and mortality associated with use of opioid pain relievers (OPRs). Efforts to address the opioid crisis have focused mainly on reducing nonmedical OPR use. Too often overlooked, however, is the need for preventing and treating opioid addiction, which occurs in both medical and nonmedical OPR users.

Purpose: To describe prescriber response to unsolicited patient reports from the Massachusetts prescription drug monitoring program (PDMP).
Methods: Prescribers were surveyed upon receipt of unsolicited reports of their patients' prescription history and three months later. We assessed prescribers' awareness of other prescribers listed in the report, their clinical assessment of medical necessity of all prescribed medications, actions taken by prescribers after receiving the report, and usefulness of the report.
Background: In 2010, the US Drug Enforcement Administration issued regulations allowing electronic prescribing of controlled substances (EPCS), a practice previously prohibited.
Objective: To carry out a survey of the experience of prescribers in the nation's first study of EPCS implementation.
Materials And Methods: Prescribers were surveyed in a community setting before and after implementation of EPCS, to assess adoption, attitudes, and challenges.
Objective: To better understand barriers associated with the adoption and use of electronic prescribing of controlled substances (EPCS), a practice recently established by US Drug Enforcement Administration regulation.
Materials And Methods: Prescribers of controlled substances affiliated with a regional health system were surveyed regarding current electronic prescribing (e-prescribing) activities, current prescribing of controlled substances, and expectations and barriers to the adoption of EPCS.
Results: 246 prescribers (response rate of 64%) represented a range of medical specialties, with 43.
Purpose: Electronic prescription monitoring programs (PMPs) have been developed in many states as a public health surveillance tool. We analyze herein 11 years of Massachusetts PMP data to evaluate trends in opioid prescribing, dispensing, and usage.
Methods: Prescription records from the Massachusetts PMP for Schedule II opioids from fiscal year 1996 to 2006 were analyzed.
Objective: Prescription drug abuse and undertreatment of pain are public health priorities in the United States. Few options to manage these problems are balanced, in simultaneously supporting pain relief and deterring prescription drug abuse. Prescription monitoring programs (PMPs) potentially offer a balanced approach; however, the medical/scientific communities are not well informed about their current status and potential risks/benefits.

The federally funded Women Embracing Life and Living (WELL) Project utilized relational strategies to facilitate systems change within and across 3 systems levels: local treatment providers, community (or region), and state. The WELL Project demonstrates that a highly collaborative, inclusive, and facilitated change process can effect services integration within agencies (intra-agency), strengthen integration within a regional network of agencies (interagency), and foster state support for services integration.

We describe an abrupt increase (at 32 degrees ) in the energy of activation for the reaction of hepatic adenylyl cyclase in the presence of glucagon or epinephrine. This increase is not seen in the presence of fluoride, prostaglandin E(1), or 1-propanol, or in the absence of cyclase stimulators. The change in energy of activation found with hormones is abolished by 1-propanol.

The effect of various hormones on the accumulation of adenosine 3':5'-cyclic monophosphate in capillary endothelial cells was determined and the cyclase was found to exhibit mixed alpha and beta characteristics. Cyclase was cytochemically localized in these endothelial cells with 5'-adenylyl-imidodiphosphate as a specific cyclase substrate and alloxan as a specific cyclase inhibitor.
