Effect of ischaemic postconditioning on markers of myocardial injury in ST-elevation myocardial infarction: a meta-analysis.

OBJECTIVES: This study aimed to perform a meta-analysis of the short-term impact of ischaemic postconditioning (IPoC) on myocardial injury in ST elevation myocardial infarction (STEMI) using surrogate cardiac biomarkers. METHODS: Eligible studies were identified using several article databases. Randomised controlled trials published between 1 January 2000 and 1 December 2021 comparing IPoC to standard of therapy in STEMI patients were included in the search. Outcomes included surrogates of myocardial injury, specifically peak troponin, creatine-kinase (CK) and CK myoglobin binding (CK-MB) enzyme levels. RESULTS: 11 articles involving 1273 patients reported on CK-MB and 8 studies involving 505 patients reported on CK. Few studies used troponin as an outcome, thus, a subanalysis of troponin dynamics was not performed. Meta-regression analysis demonstrated no significant effect of IPoC on peak CK-MB (effect size -0.41, 95% CI -1.15 to 0.34) or peak CK (effect size -0.42, 95% CI -1.20 to 0.36). Linear regression analysis demonstrated a significant correlation between a history of smoking and CK-MB in the IPoC group (p=0.038). CONCLUSIONS: IPoC does not seem to protect against myocardial injury in STEMI, except possibly in smokers. These results resonate with some studies using imaging techniques to ascertain myocardial damage. More research using troponin and cardiac imaging should be pursued to better assess the effects of IPoC on cardiovascular outcomes in STEMI.

Ischemic Postconditioning Confers No Benefit to Left Ventricular Systolic Function: A Meta-Analysis of Cardiac Magnetic Resonance Imaging Results.

Ischemic postconditioning (IPoC) is a technique suggested to reduce reperfusion injury in patients suffering acute ST-elevation myocardial infarction (STEMI), although its use is highly controversial. This meta-analysis aimed to evaluate the effect of IPoC with percutaneous coronary intervention in patients with acute STEMI, as measured by follow-up left ventricular ejection fraction (LVEF) on cardiac magnetic resonance imaging. The investigators searched PubMed, Embase, and Web of Science for all randomized controlled trials published during the last 2 decades. After the removal of duplicates, 2,021 articles from online databases had been identified using relevant search criteria. The included randomized controlled trials had studied patients with acute STEMI and Thrombolysis in Myocardial Infarction flow 0 to 1 at presentation and had measured follow-up LVEF using cardiac magnetic resonance imaging. Overall, 11 studies (n = 1,339 patients) qualified for inclusion. In each study, the control group did not differ significantly from the experimental group. The pooled data from included studies were analyzed using standardized mean difference between IPoC and control groups, and the 95% confidence interval for LVEF; the results were visualized using a forest plot. Bivariate regression analyses and 1-way analyses of LVEF coefficient ratios were done to isolate for various clinical and procedural parameters. An analysis of pooled data of the IPoC (n = 674) and control (n = 665) groups showed that IPoC did not significantly impact follow-up LVEF (using standardized mean difference 0.10, 95% confidence interval 0.00 to 0.21). Further analysis showed that IPoC did not improve follow-up LVEF when isolating for relevant clinical and procedural parameters. In conclusion, the use of IPoC as an adjunctive therapy to percutaneous coronary intervention seemingly provides no benefit to left ventricular systolic function, as quantified with cardiac magnetic resonance imaging, in patients with acute STEMI with Thrombolysis in Myocardial Infarction flow 0 to 1.

High-Risk Pulmonary Hypertension Does Not Worsen Outcomes in Heart Transplantation.

Pulmonary hypertension (PH) is a relative contraindication to heart transplantation (HT). Multiple studies showed increased mortality in patients with PH. Advances in care may have led to improved outcomes in the modern era. We analyzed patients who underwent HT at our institution between 2014 and 2018. We divided patients into 2 groups based on the presence of high-risk PH defined as either pulmonary vascular resistance >3 Wood units or transpulmonary gradient >15 mm Hg. The primary outcome was survival. Secondary outcomes were post-HT morbidity and changes in hemodynamics. Subsequently, we analyzed national trends of single organ HT recipients with a high-risk PH between 1994 and 2018 from the United Network for Organ Sharing registry. Of 98 patients who underwent HT at our center, 32% had PH. In patients without and with PH, the survival was 100% at 30 days, 87%, and 81% at 3 years (p = 0.96). In both groups, pulmonary vascular resistance and trans-pulmonary gradient decreased after HT. Nationwide data revealed 30-day survival without and with PH at 97% and 98% (p = 0.47) and 3-year survival at 86% and 87% (p = 0.84), respectively, in 2018. The proportion of recipients with PH decreased from 25% in 1994 to 19% in 2018. Recipients of HT with and without high-risk PH had similar early and late mortality in a single-center and nationwide analysis. PH improved immediately after transplant. The United Network for Organ Sharing registry analysis demonstrates continued improvement in survival in patients with PH in the modern era, whereas the relative percentage of recipients with PH decreased over time.

Thyrotoxicosis after COVID-19 Infection with a Delay in Graves' Disease Antibody Positivity.

Background and Objective. Mounting evidence implicates COVID-19 as a cause of thyroid dysfunction, including thyrotoxicosis due to both thyroiditis and Graves' disease (GD). In this report, we present a case of thyrotoxicosis following COVID-19 infection that was ultimately found to represent GD with significantly delayed diagnostic serum antibody positivity. Case Report. A 65-year-old woman with a history of uncomplicated COVID-19 infection one month prior, presented to the Emergency Department with exertional dyspnea and palpitations, and was found to be in atrial fibrillation with rapid ventricular response (AF with RVR). Labs showed subclinical hyperthyroidism and the patient was started on a beta-blocker and methimazole. One month later, thyroid-stimulating immunoglobulin (TSI) resulted negative and thyroid function tests had normalized. The clinical picture suggested thyroiditis, and methimazole was stopped. One month later, the patient again presented in AF with RVR, with labs showing overt biochemical thyrotoxicosis. Antibodies were re-tested, and the thyrotropin receptor antibody (TRAb) and TSI resulted positive, confirming GD. Discussion. Most notable in this case is the feature of delayed GD antibody positivity: the diagnostic immunoassay for GD resulted negative one and two months after infection, but was ultimately positive three months after infection. To the authors' knowledge, this represents the longest delayed antibody positivity reported to date, amongst cases of new-onset GD following COVID. Conclusion. The clinical course of GD following COVID-19 infection is highly variable. This case underscores the need for vigilance in monitoring for delayed GD antibody positivity due to the important therapeutic implications of distinguishing thyroiditis from GD.

Emotion perception and theory of mind in adolescents with major depression.

BACKGROUND: The research of theory of mind (ToM) and emotion perception (EP) in adolescents with major depressive disorder (MDD) is scarce, and no study to date has investigated the association between EP and long-term outcomes of adolescents with MDD. The aim of the current study was to evaluate ToM and EP in adolescents with MDD, as compared to healthy controls (HCs). In addition, we aimed to assess the association between impairment in ToM and EP, depressive symptom severity, and long-term outcome in the MDD group. METHODS: We compared the performance of 14 adolescents with MDD and 25 HC in the Facial Expression Recognition Task (FERT) and the Interpersonal Perception Task. We followed up with the MDD group 2 years later to assess the level of their depressive symptoms using the Children's Depression Rating Scale-Revised (CDRS-R). RESULTS: No differences were found between adolescents with MDD and HC in the ToM and FERT tasks. Also, within the MDD group, there was no association between the severity of depressive symptoms and task performance. In the MDD group, there was a significant correlation between lower levels of accuracy in the FERT during the index depressive episode and lower CDRS-R scores on follow-up 2 years later (r2 = 0.35, p = 0.021). CONCLUSIONS: EP impairments in adolescents with MDD might predict worse long-term outcome. Further research is needed to verify our findings and to assess for a possible neurobiological underpinning for the state and trait impairments in EP in adolescents with MDD.

The association between symptom severity and theory of mind impairment in children with attention deficit/hyperactivity disorder.

The aim was to investigate the correlation between ADHD symptom severity and impairments in "theory of mind" (ToM) and empathy, and the improvement in these functions following the administration of methylphenidate (MPH). Fifty children aged 6-12 years with ADHD participated in the study. Symptom severity was assessed using the Swanson, Nolan and Pelham Questionnaire-IV (SNAP-IV). ToM performance was assessed using the "ToM test" and the "Faux-Pas Recognition Test". A significant negative correlation was found between the SNAP-IV Conners index, the oppositional and deportment subscales, and ToM test scores. MPH administration improved ToM scores in a magnitude that was negatively correlated with baseline performance. Additionally, Children with more severe behavioral problems showed greater improvement in ToM following administration of MPH. We conclude that severity of ADHD symptoms, most notably behavioral symptoms, is correlated with deficits in ToM. Administration of MPH improves ToM performance, with the greatest improvement occurring in children with more severe behavioral symptoms.

Lack of association between severity of ADHD symptoms and salivary oxytocin levels.

Impairments in the reactivity of Oxytocin (OT) system were associated with interpersonal difficulties in children with ADHD. The current study aimed to explore the correlation between symptoms severity and salivary OT levels at different time-points in children with ADHD. Symptoms severity was assessed in 50 children with ADHD (28 males, mean age 9.42 ± 1.65) using the Swanson, Nolan and Pelham Questionnaire-IV (SNAP-IV) and the Strengths and Difficulties Questionnaire (SDQ). Salivary OT levels were measured at baseline, as well as 15 min after positive social interaction. There was no statistical correlation between severity of ADHD and salivary OT levels in each of the time points. We conclude that impairments in the reactivity of the OT system in children with ADHD, associated with interpersonal impairments, might be a distinct aspect of the clinical picture, differentiated from the levels of inattentive, hyperactive/impulsive or behavioral symptoms.

Universal Health Literacy Precautions Are Associated With a Significant Increase in Medication Adherence in Vulnerable Rheumatology Patients.

OBJECTIVE: Our objective was to determine the impact of the Health Literacy Universal Precautions Toolkit, adapted for rheumatology, on medication adherence, patient satisfaction, and feasibility in all patients; its effect on the clinical disease activity index (CDAI) was studied in a rheumatoid arthritis (RA) subpopulation. METHODS: Data collected during a 6-month prospective quality assurance intervention was compared with data from a prior 6-month period. Interventions included 1) encouraging questions, 2) teach-back communication, and 3) brown-bag medication review. Analysis was performed using linear regression or generalized estimating equation (GEE) regression. RESULTS: During the intervention period, 46 physicians completed 1737 patient visits. Questions were encouraged, and teach-back communication was performed in more than 90% of visits. Brown-bag medication reviews were performed in 47% of visits overall and 69% of visits in a subgroup that received additional reminder calls. Visit duration and patient satisfaction were not significantly increased. Adherence for rheumatology-related medications that were prescribed both before and during the intervention increased by 22% (P ≤ 0.001; by GEE). Teach-back communication predicted a statistically significant improvement in medication adherence in this subpopulation (by linear regression). The mean CDAI did not improve; however, African American race and Hispanic ethnicity were associated with a decreased CDAI (by GEE). CONCLUSION: Implementation of the Health Literacy Universal Precautions Toolkit, adapted for rheumatology, improved medication adherence in our safety-net clinic, with particularly strong effects seen with teach-back communication. In certain populations, use of the toolkit may also improve RA disease activity. This is the first study to document improved medication adherence with this intervention in a real-world setting.

Disclosing Adverse Events to Patients: International Norms and Trends.

OBJECTIVES: There is a growing expectation in health systems around the world that patients will be fully informed when adverse events occur. However, current disclosure practices often fall short of this expectation. METHODS: We reviewed trends in policy and practice in 5 countries with extensive experience with adverse event disclosure: the United States, the United Kingdom, Canada, New Zealand, and Australia. RESULTS: We identified 5 themes that reflect key challenges to disclosure: (1) the challenge of putting policy into large-scale practice, (2) the conflict between patient safety theory and patient expectations, (3) the conflict between legal privilege for quality improvement and open disclosure, (4) the challenge of aligning open disclosure with liability compensation, and (5) the challenge of measurement related to disclosure. CONCLUSIONS: Potential solutions include health worker education coupled with incentives to embed policy into practice, better communication about approaches beyond the punitive, legislation that allows both disclosure to patients and quality improvement protection for institutions, apology protection for providers, comprehensive disclosure programs that include patient compensation, delinking of patient compensation from regulatory scrutiny of disclosing physicians, legal and contractual requirements for disclosure, and better measurement of its occurrence and quality. A longer-term solution involves educating the public and health care workers about patient safety.

Disclosure of adverse events in the United States and Canada: an update, and a proposed framework for improvement.

There is consensus that physicians, health professionals and health care organizations should discuss harm that results from health care delivery (adverse events), including the reasons for harm, with patients and their families. Thought leaders and policy makers in the USA and Canada support this goal. However, there are gaps in both countries between patients and physicians in their attitudes about how errors should be handled, and between disclosure policies and their implementation in practice. This paper reviews the state of disclosure policy and practice in the two countries, and the barriers to full disclosure. Important barriers include fear of consequences, attitudes about disclosure, lack of skill and role models, and lack of peer and institutional support. The paper also describes the problem of the second victim, a corollary of disclosure whereby health care workers are also traumatized by the same events that harm patients. The presence of multiple practical and personal barriers to disclosure suggests the need for a comprehensive solution directed at multiple levels of the health care system, including health departments, institutions, local managers, professional staff, patients and families, and including legal, health system and local institutional support. At the local level, implementation could be based on a translating-evidence-into-practice framework. Applying this framework would involve the formation of teams, training, measurement and identification of local barriers to achieving universal disclosure of adverse events. Significance for public healthIt is inevitable that some patients will be harmed rather than helped by health care. There is consensus that patients and their families must be told about these harmful events. However, there are gaps between patient and physician attitudes about how errors should be handled, and between disclosure policies and their implementation. There are important barriers that impede disclosure, including fear of consequences, attitudes about disclosure, lack of skill, and lack of institutional support. A related problem is that of the second victim, whereby health care workers are traumatized by the same harmful events. This can impair their performance and further compromise safety. The problem is unlikely to be solved by focusing solely on increasing disclosure. A comprehensive solution is needed, directed at multiple levels of the health care system, including health departments, institutions, local managers, professional staff, patients and families, and including legal, health system and local institutional support.

Limited health literacy is a common finding in a public health hospital's rheumatology clinic and is predictive of disease severity.

BACKGROUND: Health literacy (HL) is associated with outcomes in many conditions, but little is known about its impact on arthritic diseases. OBJECTIVES: We sought to determine whether HL is related to disease activity and severity in patients with rheumatoid arthritis (RA). METHODS: English-speaking adult RA patients were recruited for this cross-sectional study. Background information was ascertained by medical record review; Disease Activity Score 28 (DAS-28) scores were determined by providers; subjects completed the Multidimensional Health Assessment Questionnaire (MDHAQ), demographic questionnaires, and validated HL instruments, including the Short Test of Functional Health Literacy in Adults, Rapid Estimate of Adult Literacy in Medicine, and the single-item literacy screener. We used linear regression to assess whether HL was associated with MDHAQ and DAS-28 scores. RESULTS: One hundred ten subjects participated in the study. Limited HL was a common finding, especially among ethnic minorities. The single-item literacy screener results were predictive of lower MDHAQ scores by univariate regression analysis. Similar trends were observed for the Short Test of Functional Health Literacy in Adults and Rapid Estimate of Adult Literacy in Medicine. The relationship between the single-item literacy screener and MDHAQ remained statistically significant in multivariate analysis that controlled for the impact of demographic features and RA disease characteristics. Health literacy scores were not associated with DAS-28 scores. CONCLUSIONS: Health literacy was independently associated with functional impairment in English-speaking RA patients at an urban safety-net clinic. This new finding suggests that RA functional status might be improved by strategies that target limited HL's causal pathways.

Wrong-site and wrong-patient procedures in the universal protocol era: analysis of a prospective database of physician self-reported occurrences.

OBJECTIVE: To determine the frequency, root cause, and outcome of wrong-site and wrong-patient procedures in the era of the Universal Protocol. DESIGN: Analysis of a prospective physician insurance database performed from January 1, 2002, to June 1, 2008. Deidentified cases were screened using predefined taxonomy filters, and data were analyzed by evaluation criteria defined a priori. SETTING: Colorado. PATIENTS: Database contained 27 370 physician self-reported adverse occurrences. MAIN OUTCOME MEASURES: Descriptive statistics were generated to examine the characteristics of the reporting physicians, the number of adverse events reported per year, and the root causes and occurrence-related patient outcomes. RESULTS: A total of 25 wrong-patient and 107 wrong-site procedures were identified during the study period. Significant harm was inflicted in 5 wrong-patient procedures (20.0%) and 38 wrong-site procedures (35.5%). One patient died secondary to a wrong-site procedure (0.9%). The main root causes leading to wrong-patient procedures were errors in diagnosis (56.0%) and errors in communication (100%), whereas wrong-site occurrences were related to errors in judgment (85.0%) and the lack of performing a "time-out" (72.0%). Nonsurgical specialties were involved in the cause of wrong-patient procedures and contributed equally with surgical disciplines to adverse outcome related to wrong-site occurrences. CONCLUSIONS: These data reveal a persisting high frequency of surgical "never events." Strict adherence to the Universal Protocol must be expanded to nonsurgical specialties to promote a zero-tolerance philosophy for these preventable incidents.

Health literacy predicts the discrepancy between patient and provider global assessments of rheumatoid arthritis activity at a public urban rheumatology clinic.

OBJECTIVE: Numerous studies report that significant discordance exists between patient and provider [physician] measures of rheumatoid arthritis (RA). We examined whether health literacy explains this discordance. METHODS: We recruited English-speaking adult patients with RA for this cross-sectional study. Subjects completed 2 versions of patient global assessments of disease activity (PTGA), using standard terminology from the Multi-Dimensional Health Assessment Questionnaire (MDHAQ) and the 28-joint count Disease Activity Score 28 (DAS28). The provider global assessment (MDGA) was also obtained. The discrepancy between PTGA and MDGA was calculated as the absolute difference between these assessments. We used validated instruments [Short Test of Functional Health Literacy in Adults (S-TOFHLA) and Rapid Estimate of Adult Literacy in Medicine (REALM)] and linear regression to determine whether health literacy predicts disease measure discrepancy. RESULTS: The study included 110 subjects. Limited health literacy was a common finding by both the REALM and S-TOFHLA. PTGA and MDGA showed fair to good correlation (r = 0.66-0.68), although both versions of the PTGA were significantly higher than MDGA by the t-test (p < 0.001). The S-TOFHLA and REALM both were associated with the absolute difference between the MDGA and PTGA by linear regression, and results remained statistically significant in multivariate analysis. CONCLUSION: Health literacy was independently associated with the extent of discrepancy between PTGA and MDGA in English-speaking patients with RA at an urban clinic. This finding should influence our interpretation of disease measures.

A concise evaluation and management curriculum for physicians in training improved billing at an outpatient academic rheumatology clinic.

PURPOSE: To study whether providing house staff with a brief lecture and handout about proper documentation could improve billing at an academic rheumatology clinic. METHOD: The authors created an educational sheet about documentation and billing after a review of the common documentation omissions responsible for down coding (Appendix, Supplemental Digital Content 1, available at: http://links.lww.com/RHU/A8). Beginning in November of 2006, the house staff were provided with this sheet and a brief lecture regarding how outpatient evaluation and management levels of service are coded. The results of clinic billing from January 1, 2006 to October 31, 2006 and November 1, 2006 to August 31, 2007 were obtained from the physician billing office. The authors compared the average level of service, by appointment type, in the prepost comparison periods using the student t test. RESULTS: There was a significant improvement in the level of service billed for new visits (P < 0.001), consults (P < 0.001), and return visits (P < 0.001) after November 1, 2006. The percentage of patients evaluated for the first time who were billed as consults improved from 15% to 78% (P < 0.001 by chi2). These changes resulted in $34,342 of additional billing during the postintervention period. DISCUSSION: A simple strategy for educating the house staff about proper documentation of the history, physical examination, and clinical decision making resulted in a significant improvement in an academic rheumatology division's outpatient billing.

Disclosing errors and adverse events in the intensive care unit.

OBJECTIVE: To review the issue of disclosing errors in care and adverse events that have caused harm to patients in critical care. DESIGN: Review the scope of the problem, the definitions of errors and adverse events, and the benefits and problems of disclosing errors and adverse events and provide an approach by which to have these difficult discussions. SETTING: Medical center. PATIENTS: Critically ill patients and their families. INTERVENTIONS: Applying a systematic framework for disclosing errors and adverse events to affected patients and their families. MEASUREMENTS AND MAIN RESULTS: Several national organizations mandate that physicians discuss errors in care and adverse events that have caused harm with affected patients, but failure to do so is a common problem in critical care as surveys of intensivists indicate that, although most believe that errors should be disclosed, few routinely do so. The likelihood of an adverse event is increased in intensive care units because of the nature of critical care. Not all errors or adverse events require disclosure. There are ethical, financial, legal, systems, and personal benefits to disclosing errors, and disclosure discussions should address common patient concerns. CONCLUSIONS: Failure to disclose errors and adverse events in critical care is an important and common problem. There are numerous reasons why errors and adverse events should be disclosed, and use of a standard framework for doing so will facilitate the process.

Invite, listen, and summarize: a patient-centered communication technique.

The need for physicians to have patient-centered communication skills is reflected in the educational objectives of numerous medical schools' curricula and in the competencies required by groups such as the Accreditation Council for Graduate Medical Education. An innovative method for teaching communications skills has been developed at the University of Colorado School of Medicine as part of its three-year, longitudinal course focusing on basic clinical skills required of all physicians. The method emphasizes techniques of open-ended inquiry, empathy, and engagement to gather data. Students refer to the method as ILS, or Invite, Listen, and Summarize. ILS was developed to combat the high-physician-control interview techniques, characterized by a series of "yes" or "no" questions. The authors began teaching the ILS approach in 2001 as one basic exercise and have since developed a two-year longitudinal communications curriculum. ILS is easy to use and remember, and it emphasizes techniques that have been shown in other studies to achieve the three basic functions of the medical interview: creating rapport, collecting good data, and improving compliance. The skills are taught using standardized patients in a series of four small-group exercises. Videotaped standardized patient encounters are used to evaluate the students. Tutors come from a variety of disciplines and receive standardized training. The curriculum has been well received. Despite the fact that the formal curriculum only occurs in the first two years, there is some evidence that it is improving students' interviewing skills at the end of their third year.
