Ketamine as part of multi-modal analgesia may reduce opioid requirements following cardiac surgery: a retrospective observational cohort study

Hall, James; Chung, Juri; Khilkin, Michael; Elkomos-Botros, George
BACKGROUND:Postoperative pain control in cardiac surgery is often managed with opioid medications. Insufficient analgesia can result in complications including splinting, pneumonia, and delay of appropriate rehabilitation. Given the risks and adverse effects of opioids including sedation, respiratory depression, delirium, and decreased gastrointestinal motility, hyperalgesia and potential for addiction, strategies for opioid reduction are likely to improve outcomes, therefore multimodal opioid sparing pain regimens are preferred. Recently, there is increased evidence that low dose Ketamine, an N-methyl-D-Aspartate (NMDA) receptor antagonist, is safe and effective for analgesia in postoperative patients and may be appropriate to this setting. METHODS:This is a single center, retrospective, observational, cohort study over a one year period involving postoperative adult cardiac surgery comparing those who received a single dose of postoperative ketamine, 0.3 mg/kg over 30 min, with those who did not receive any ketamine. Other analgesic protocols were similar between groups and did not include additional ketamine. A total of 120 patient charts were reviewed, of which 96 met inclusion criteria, 32 in the ketamine group and 64 in the standard care group. Charts were reviewed for opioid and other pain medication requirements during the postoperative period and on discharge, and for secondary outcomes: hospital length of stay, ICU length of stay, in-hospital and 30-day mortality, 30-day readmission, and rates of delirium, emergence reactions, and need for escalated respiratory support. RESULTS:The group who received postoperative ketamine required 28.8 morphine milligram equivalents (MME) less postoperative opioid (90.1 mg vs 118.9 mg, p = 0.167), and was prescribed an average of 15.8 MME less on discharge (p < 0.001). Intraoperatively, both groups received 1000 mg acetaminophen, 2 mg intravenous morphine and 100 mcg fentanyl, 26 MME, by protocol. No ketamine was administered intraoperatively or preoperatively. The groups differed in respect to operation type and controlling for this parameter failed to achieve significance in needs during admission (p = 0.215), but remained significant on discharge (p = 0.02). The non-ketamine group received more ketorolac (15.5 vs 10.1, p = 0.06). The ketamine group required less acetaminophen but more gabapentin. There was no difference in hospital or ICU length of stay. There was no delirium or mortality in either group. Respiratory depression occurred in 15 patients who all subsequently received ketamine. No patient developed respiratory depression after ketamine. CONCLUSIONS:Ketamine may be a reasonable choice for postoperative cardiac surgery analgesia and may reduce the need for opioids on discharge, and possibly during admission.

Reciprocal relationships between adolescent mental health difficulties and alcohol consumption

Kiri, Janet; Hall, James; Cortese, Samuele; Brandt, Valerie
The directionality of the relationship between adolescent alcohol consumption and mental health difficulties remains poorly understood. This study investigates the longitudinal relationship between alcohol use frequency, internalizing and externalizing symptoms from the ages of 11 to 17. We conducted a random-intercept cross-lagged panel model across three timepoints (ages: 11yrs, 14yrs, 17yrs; 50.4% female) in the Millennium Cohort Study (N = 10,647). Survey weights were used to account for attrition. At each timepoint, past month alcohol use frequency was self-reported, parents and cohort members reported internalizing/externalizing symptoms using the Strengths and Difficulties Questionnaire. We controlled for alcohol expectancies, sex, and four cumulative risk indices (perinatal risk, early childhood adverse parenting, longitudinal parent-level risk occurrence, and persistent household socioeconomic deprivation). More frequent past month alcohol use at age 11 predicted increased internalizing symptoms at age 14 (β = 0.06; p =.01). More frequent past month alcohol use at age 14 predicted increased externalizing symptoms at age 17 (β = 0.11; p <.001). Increased internalizing symptoms consistently predicted reduced alcohol use at the next timepoint throughout the study period (11 years: β= -0.04; p =.03; 14 years: β= -0.09; p <.001). Increased externalizing symptoms at age 11 predicted increased alcohol consumption at age 14 (β = 0.06; p =.004). Frequent adolescent alcohol consumption represents a significant risk for subsequent mental health difficulties. Externalizing symptoms and alcohol use frequency appear to exacerbate one another. Internalizing symptoms may reduce the risk of frequent alcohol consumption. Incorporating routine alcohol screening into adolescent mental health treatment settings could reduce the risk of comorbid externalizing and alcohol use disorders.

Acute Rheumatic Fever

Chowdhury, Sadakat; Koziatek, Christian A.; Rajnik, Michael
Acute rheumatic fever (ARF) is an immune-mediated nonsuppurative complication of group A streptococcal (GAS) pharyngitis. Approximately 470,000 new cases of ARF occur annually, with a more significant disease burden in developing countries with higher rates of untreated or inadequately treated GAS infections. Globally, over 275,000 deaths yearly are attributed to rheumatic heart disease (RHD). The most significant contributors to the spread of GAS pharyngitis are household overcrowding, poor sanitation, and inadequate access to healthcare. The pathophysiology of ARF is characterized by an aberrant immune response to GAS infection triggered by molecular mimicry between GAS antigens and self-antigens. This immune response typically manifests 2 to 4 weeks after the initial GAS infection and may lead to the development of carditis, valvulitis, Sydenham chorea, subcutaneous nodules, erythema marginatum, and polyarthritis that is usually migratory. The severity and distribution of these manifestations vary significantly between individuals making the diagnosis of ARF challenging. Early recognition of ARF using the modified Jones criteria is essential in treating acute infection and preventing complications. A major long-term consequence is RHD, which carries significant morbidity and mortality.

Complete thrombosis of a bioprosthetic mitral valve and left atrium in a patient on venoarterial extracorporeal membrane oxygenation with favorable outcome [Case Report]

Hall, James; Khilkin, Michael; Abrol, Sunil
Intra-cardiac thrombosis is a potentially devastating complication of extracorporeal membrane oxygenation (ECMO) mechanical circulatory support. We present here a patient who suffered complete thrombosis of a fresh mitral prosthesis and left atrium in the setting of ECMO with aortic insufficiency who was treated with repeat valve replacement and thrombectomy. To our knowledge, she is the only patient in the reported literature to have survived this complication.

State Public Health Communications and Public Compliance during the Pre-election SARS-CoV-2 Pandemic: Interpreting the Effectiveness of Messaging Guidelines Utilizing Moral Foundations Theory

Hall, James F.
Background: State-level public health messaging during the pre-election coronavirus pandemic was very inconsistent. Moral motivational content of the messages, as characterized by moral foundations theory, may have contributed to the degree of compliance in particular states. More attention to this content might result in greater compliance and a lessening of the pandemic's severity. Methods: A comprehensive review of official state messaging in six U.S. states (California, Florida, Massachusetts, Mississippi, New York, and Texas) was reviewed for the number and distribution of moral foundations as described by moral foundations theory. A search was done for state-level data concerning compliance with mask-wearing and social distancing, the primary public precautionary measures during the pandemic. Rates of compliance by the state were compared with messaging content and analyzed for associations and correlations with the known partisan leanings of the states. Examples of messages with balanced moral foundations, which might be prospectively employed for greater acceptance, were presented. All data were gathered prior to the introduction of the first available vaccine. Results: Message review and compliance data suggested that the quantity and proportion of coronavirus-related official messages and the utilization of a balanced combination of moral foundations were associated with higher levels of compliance with the recommended public health measures and lower infection rates. The political orientations of states did not align with the use of known conservative/liberal preferred moral foundations as previously established by Moral Foundations Theory. Conclusion: Adjusting messaging with attention to the balanced employment of moral foundations can lead to wider acceptance of and compliance with preventive public health measures.
