Managing Opioid-Tolerant Patients in the Perioperative Surgical Home.

Management of acute postoperative pain is important to decrease perioperative morbidity and improve patient satisfaction. Opioids are associated with potential adverse events that may lead to significant risk. Uncontrolled pain is a risk factor in the transformation of acute pain to chronic pain. Balancing these issues can be especially challenging in opioid-tolerant patients undergoing surgery, for whom rapidly escalating opioid doses in an effort to control pain can be associated with increased complications. In the perioperative surgical home model, anesthesiologists are positioned to coordinate a comprehensive perioperative analgesic plan that begins with the preoperative assessment and continues through discharge

The Efficacy of Peripheral Opioid Antagonists in Opioid-Induced Constipation and Postoperative Ileus: A Systematic Review of the Literature.

Opioid-induced constipation has a negative impact on quality of life for patients with chronic pain and can affect more than a third of patients. A related but separate entity is postoperative ileus, which is an abnormal pattern of gastrointestinal motility after surgery. Nonselective μ-opioid receptor antagonists reverse constipation and opioid-induced ileus but cross the blood-brain barrier and may reverse analgesia. Peripherally acting μ-opioid receptor antagonists target the μ-opioid receptor without reversing analgesia. Three such agents are US Food and Drug Administration approved. We reviewed the literature for randomized controlled trials that studied the efficacy of alvimopan, methylnaltrexone, and naloxegol in treating either opioid-induced constipation or postoperative ileus. Peripherally acting μ-opioid receptor antagonists may be effective in treating both opioid-induced bowel dysfunction and postoperative ileus, but definitive conclusions are not possible because of study inconsistency and the relatively low quality of evidence. Comparisons of agents are difficult because of heterogeneous end points and no head-to-head studies

Long-term prediction of adherence to continuous positive air pressure therapy for the treatment of moderate/severe obstructive sleep apnea syndrome

BACKGROUND: Continuous positive airway pressure (CPAP) therapy is a highly effective treatment for obstructive sleep apnea syndrome (OSAS). However, poor adherence is a limiting factor, and a significant proportion of patients are unable to tolerate CPAP. The aim of this study was to determine predictors of long-term non-compliance with CPAP. METHODS: CPAP treatment was prescribed to all consecutive patients with moderate or severe OSAS (AHI ≥15 events/h) (n = 295) who underwent a full-night CPAP titration study at home between February 1, 2002 and December 1, 2016. Adherence was defined as CPAP use for at least 4 h per night and five days per week. Subjects had periodical follow-up visits including clinical and biochemical evaluation and assessment of adherence to CPAP. RESULTS: Median follow-up observation was 74.8 (24.2/110.9) months. The percentage of OSAS patients adhering to CPAP was 41.4% (42.3% in males and 37.0% in females), and prevalence was significantly higher in severe OSAS than in moderate (51.8% vs. 22.1%; p < 0.001; respectively). At multivariate analysis, lower severity of OSAS (HR = 0.66; CI 95 0.46-0.94) p < 0.023), cigarette smoking (HR = 1.72; CI 95 1.13-2.61); p = 0.011), and previous cardiovascular events (HR = 1.95; CI 95 1.03-3.70; p = 0.04) were the only independent predictors of long-term non-adherence to CPAP after controlling for age, gender, and metabolic syndrome. CONCLUSIONS: In our cohort of patients with moderate/severe OSAS who were prescribed CPAP therapy, long-term compliance to treatment was present in less than half of the patients. Adherence was positively associated with OSAS severity and negatively associated with cigarette smoking and previous cardiovascular events at baseline

Circulating skeletal muscle related microRNAs profile in Piedmontese cattle during different age

Piedmontese cattle is known for double-muscle phenotype. MicroRNAs (miRNAs) play important role as regulators in skeletal muscle physiological processes, and we hypothesize that plasma miRNAs expression profiles could be affected by skeletal muscle growth status related to age. Plasma samples of cattle were collected during four different ages from first week of life until the time of commercial end of the fattening period before slaughter. Small-RNA sequencing data analysis revealed the presence of 40% of muscle-related miRNAs among the top 25 highly expressed miRNAs and, 19 miRNAs showed differential expression too. Using qRT-PCR, we validated in a larger bovine population, miRNAs involved in skeletal muscle physiology pathways. Comparing new-born with the other age groups, miR-10b, miR-126-5p, miR-143 and miR-146b were significantly up-regulated, whereas miR-21-5p, miR-221, miR-223 and miR-30b-5p were significantly down-regulated. High expression levels of miR-23a in all the groups were found. Myostatin, a negative regulator of skeletal muscle hypertrophy, was predicted as the target gene for miR-23a and miR-126-5p and we demonstrated their direct binding. Correlation analysis revealed association between miRNAs expression profiles and animals’ weights along the age. Circulating miRNAs could be promising for future studies on their biomarker potentialities to beef cattle selection

Fixing the Climate with Experimentalist Governance? How?

Official climate data tell us with a very low degree of uncertainty that global temperatures for the months of September and October 2023 represent the highest anomaly ever recorded. The challenge before us, of large and timely phasing out of greenhouse gas emissions is enormous in scale and complexity. There appear to be no ready and fast solutions but there is a need for profound technological changes in several different production sectors. Finally, these solutions must be adopted quickly and promptly to reduce the magnitude of irreversible changes to the planet’s climate. The good news, the most reputable studies tell us, is that the technical knowledge available to us allows us to have real solutions. In the latest International Energy Agency report, World Energy Outlook 2023 released just a few days ago, institute director Fatih Birol writes in the preface that ‘[t]oday, solar power, wind power, efficiency and electric cars are all well established and readily available. We have at our disposal the lasting solutions to today’s energy dilemmas.’ We can thus truly aspire to have the opportunity to be the first generation to have transformed their lifestyles into fully sustainable modes. On October 26, 2023, the Law department of Roma Tre University hosted a special event within the ‘Inequality in Rome Seminar Series’, hosting Prof. Charles Sabel of Columbia University School of Law to discuss his new volume Fixing the Climate: Strategies for an Uncertain World, co-authored with Prof. David Victor of the University of California San Diego. This special event was organized in collaboration with the Forum Disuguaglianze and Diversità, an Italian organization that brings together researchers and civil society members to design and advocate for public policies that aim at reducing the levels of inequality in the country. Sabel and Victor’s book proposes an innovative method that can work in the context of radical and pervasive uncertainty about the solutions to be undertaken to make the energy and ecological transition more affordable. How? The core of the book lies in the model of global governance of climate change that it promotes. The overall premise is clear – no response to climate change will succeed without international cooperation (p. 153).The problem is what type of cooperation international law should embrace. The answer is, according to the authors, ‘experimentalist governance’ (hereinafter EG), a system that goes beyond the Paris Agreement (2015). They argue that such Agreement has failed to achieve its goals. The book instead puts forward the model of governance endorsed by the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer – a history of success, as the Authors rightly maintain (see pp. 4 to 7 and Ch 2). The book forcefully suggests that we need to reward those who innovate and destabilize the status quo and penalize those who do not want to change through experimental and concrete processes of collaboration between business, between State, business, and citizens, and between States. The states should set ambitious standards and broad goals that are able to incentivize economic agents to act. Moreover, those who set standards interact with those who must solve problems on the ground and implement solutions, following an iterative process of mutual correction of the roadmap and concrete goals to achieve. Such solutions aim at complementing classical marketbased approaches. Indeed, the experimentalist governance approach operates in a decentralized manner, coordinating myriads of individuals, institutions, and economic agents just as happens in markets but not by means of prices, but by setting standards that are continually revised by accumulating new information, if necessary, through deliberative and discussion processes. A form of deliberation that uses doubt, disagreement, and a peer review process to advance the technological frontier even in an environment of profound uncertainty. In this article, we propose the main issues and questions that were raised during the seminar by the panelists Prof. Barbara Annicchiarico, Prof. Roberto Baratta, Prof. Tommaso di Marcello, as well as from the coordinator Prof. Salvatore Morelli. Prof. Charles Sabel provides his responses in turn

Characterizing the patterns of electronic health record-integrated secure messaging use: Cross-sectional study

BACKGROUND: Communication among health care professionals is essential for the delivery of safe clinical care. Secure messaging has rapidly emerged as a new mode of asynchronous communication. Despite its popularity, relatively little is known about how secure messaging is used and how such use contributes to communication burden. OBJECTIVE: This study aims to characterize the use of an electronic health record-integrated secure messaging platform across 14 hospitals and 263 outpatient clinics within a large health care system. METHODS: We collected metadata on the use of the Epic Systems Secure Chat platform for 6 months (July 2022 to January 2023). Information was retrieved on message volume, response times, message characteristics, messages sent and received by users, user roles, and work settings (inpatient vs outpatient). RESULTS: A total of 32,881 users sent 9,639,149 messages during the study. Median daily message volume was 53,951 during the first 2 weeks of the study and 69,526 during the last 2 weeks, resulting in an overall increase of 29% (P=.03). Nurses were the most frequent users of secure messaging (3,884,270/9,639,149, 40% messages), followed by physicians (2,387,634/9,639,149, 25% messages), and medical assistants (1,135,577/9,639,149, 12% messages). Daily message frequency varied across users; inpatient advanced practice providers and social workers interacted with the highest number of messages per day (median 19). Conversations were predominantly between 2 users (1,258,036/1,547,879, 81% conversations), with a median of 2 conversational turns and a median response time of 2.4 minutes. The largest proportion of inpatient messages was from nurses to physicians (972,243/4,749,186, 20% messages) and physicians to nurses (606,576/4,749,186, 13% messages), while the largest proportion of outpatient messages was from physicians to nurses (344,048/2,192,488, 16% messages) and medical assistants to other medical assistants (236,694/2,192,488, 11% messages). CONCLUSIONS: Secure messaging was widely used by a diverse range of health care professionals, with ongoing growth throughout the study and many users interacting with more than 20 messages per day. The short message response times and high messaging volume observed highlight the interruptive nature of secure messaging, raising questions about its potentially harmful effects on clinician workflow, cognition, and errors
