Opiates act through opioid receptors to diminish pain. Here, we investigated whether mu (MOR) and delta (DOR) receptor endogenous activity assessed in the whole mouse body or in particular at peripheral receptors on primary nociceptive neurons, control colonic pain. ⋯ Knockout mice for mu and delta opioid receptor have augmented colon sensitivity in the CRD assay. It shows endogenous mu and delta opioid analgesia that may be explored as potential targets for alleviating chronic intestinal pain.

This study examined outcomes and predictors of different types of responses to child pain used by caregivers of youth with chronic disease. Sixty-six children and adolescents (ages 7-18) with juvenile idiopathic arthritis answered questions about pain, pain interference in activities, and mood on a smartphone three times per day for one month, while a caregiver contemporaneously answered questions about their own mood and use of protecting, monitoring, minimizing, or distracting responses to their child's pain. Multilevel models were used to evaluate (a) how a child's pain and pain interference changes after a caregiver uses different types of pain responses; (b) the extent to which caregiver responses to pain vary across days; and (c) whether variability in caregiver responses to pain is predicted by changes in child pain characteristics, child mood, and/or caregiver mood. ⋯ Caregiver pain responses varied considerably across days, with caregivers responding with more protecting and monitoring responses and fewer minimizing responses at moments when their child reported high levels of pain unpleasantness and pain interference. Caregivers also were found to respond with fewer protective responses at moments when they themselves were in a more positive mood. Implications for clinical recommendations and future studies are discussed.

ReviewNew Innovations in Circulatory Support With Ventricular Assist Device and Extracorporeal Membrane Oxygenation Therapy.
The past decade has seen an exponential increase in the application and development of durable long-term as well as nondurable short-term mechanical circulatory support for cardiogenic shock and acute or chronic heart failure. Support has evolved from bridge-to-transplant to destination therapy, bridge to rescue, bridge to decision making, and bridge to a bridge. Notable trends include device miniaturization, minimally invasive and/or percutaneous insertion, and efforts to superimpose pulsatility on continuous flow. ⋯ However, despite-or perhaps because of-the enhanced equipment now available, mechanical circulatory support is an expensive, complex, resource-intensive modality. It requires considerable expertise that should preferably be centralized to highly specialized centers. Formidable challenges remain: systemic inflammatory response syndromes and vasoplegia after device insertion; postoperative sepsis; optimal anticoagulation regimens to prevent device-induced thrombosis and cerebral thromboembolism; wound site, intracranial, and gastrointestinal bleeding; multisystem injury and failure; patient dissatisfaction (even when providers consider the procedure a "success"); and ethical decision making in conditions of futility.

Impact of Acute Kidney Injury in Patients Hospitalized With Pneumonia.
Pneumonia is a common cause of hospitalization and can be complicated by the development of acute kidney injury. Acute kidney injury is associated with major adverse kidney events (death, dialysis, and durable loss of renal function [chronic kidney disease]). Because pneumonia and acute kidney injury are in part mediated by inflammation, we hypothesized that when acute kidney injury complicates pneumonia, major adverse kidney events outcomes would be exacerbated. We sought to assess the frequency of major adverse kidney events after a hospitalization for either pneumonia, acute kidney injury, or the combination of both. ⋯ When acute kidney injury accompanies pneumonia, postdischarge outcomes are worse than either diagnosis alone. Patients who survive a pneumonia hospitalization and develop acute kidney injury are at high risk for major adverse kidney events including death and should receive careful follow-up.

Medical case management has improved in the past few decades, changing the dynamic interaction between depression and prevalent medical diseases. It is relevant to describe the comorbidity between depression and medical diseases to further improve the effectiveness of case management. We analyzed the data of adults aged 20 years and older, who completed depression screening as a part of the National Health and Nutrition Examination Survey, 2005 to 2012. ⋯ Moderate/severe depression was associated with a history of heart disease among men (2.45 [1.19-5.06]) and angina/angina pectoris among women (2.13 [1.07-4.26]). No associations were found between depression and cancer/malignancy, either among men or women. The potential impact of pain management on depression prevention among general population is substantial; more efforts are needed to assess chronic pain to facilitate timely prevention and treatment of depression and comorbid medical conditions.
