Movement-based mind-body interventions for cardiac rehabilitation: An updated systematic review of randomized controlled trials.

This study aimed to assess evidence for the effect of movement-based mind-body interventions (MMBIs) for cardiac rehabilitation (CR). Six databases were searched from January 1995 to September 2020. All randomized controlled trials (RCTs) evaluated the effect of MMBIs on heart disease (HD) patients' physical and psychological outcomes. Two reviewers independently assessed the quality of all the included studies using the revised Cochrane risk-of-bias tool for RCTs. Sixteen RCTs (5160 participants) published between 1996 and 2020 met all inclusion criteria. In total, these studies investigated the effect of MMBIs for CR. Outcome measures that emerged in these studies included physical and psychological, and/or biochemical parameters to comprehensively evaluate the effects of MMBIs on HD patients. Overall, these studies suggest that MMBIs seem to be an alternative with the optimal CR option.

Prognostic value of peak lactate during cardiopulmonary bypass in adult cardiac surgeries: A retrospective cohort study.

OBJECTIVE: Tissue hypoperfusion during cardiopulmonary bypass (CPB) affects cardiac surgical outcomes. Lactate, an end product of anaerobic glycolysis from oxygen deficit, is a marker of tissue hypoxia. In this study, we aimed to identify the prognostic value of blood lactate level during CPB in predicting outcomes in adults undergoing cardiac surgeries. MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who underwent cardiac surgeries with CPB from January 2015 to December 2015. Data about the characteristics of patients, preoperative status, type of surgery, and intraoperative lactate levels were collected. The outcomes were in-hospital mortality and complications. The receiver operating characteristics (ROC) curves were used to assess the ability of peak lactate level during CPB in predicting in-hospital mortality. RESULTS: A total of 97 patients, including 61 who underwent emergent or urgent surgery, were enrolled. The types of surgery included coronary artery bypass grafting (CABG, n = 52), valve surgery (n = 27), combined surgery (CABG and valve surgery, n = 4), great vessel surgery (including aortic dissection, n = 9), and others (n = 5). The median CPB time was 139 min (interquartile range = 120-175). The median initial lactate and peak lactate levels during CPB were 0.9 and 4.2 mmol/L, respectively. In-hospital mortality was 14.4%, which was significantly associated with age and peak lactate level in the multivariate logistic regression model. When the peak lactate level during CPB reached 7.25 mmol/L, in-hospital mortality could be predicted with an area under the ROC curve of 0.75 (95% confidence interval: 0.59-0.90; P = 0.003), with a sensitivity of 57% and specificity of 93%. CONCLUSION: Hyperlactatemia during CPB was associated with increased in-hospital mortality. Thus, early detection of such conditions and aggressive postoperative care are important.

Sudden Cardiac Death Associated with Anomalous Origin of the Left Main Coronary Artery from the Right Sinus, with an Intramural Course.

Anomalous origin of the left main coronary artery from the right sinus of Valsalva is extremely rare and can lead to sudden cardiac death. We report a case in which an 18-year-old college student collapsed immediately after a long-distance run of 10 km. After cardiopulmonary resuscitation and electrical shock for ventricular fibrillation, she experienced a return of spontaneous circulation. Cardiac catheterization and cardiac computed tomographic angiography revealed an unusually long intramural course of the left main coronary artery from the right sinus of Valsalva. The young woman underwent a successful unroofing operation for coronary artery correction. She remained asymptomatic upon exercise during 2.5 years of follow-up.

Clinical Characteristics and In-Hospital Prognosis of Infective Endocarditis in Two Eastern Counties of Taiwan.

BACKGROUND: Infective endocarditis (IE) is a common and potentially serious disease. Although it is an illness that affects populations around the world, narrower descriptions of this disease as it impacts specific regions are uncommon. We analyzed the clinical characteristics of IE patients from two eastern counties in Taiwan and studied the relationship between the isolated pathogens and clinical outcomes in these patients. METHODS: This is a retrospective chart review study which enrolled patients who received services between January 2007 and December 2010. Subsequent to chart review, IE was confirmed in a total of 55 patients by the modified Duke criteria. RESULTS: Of these patients, 17 (31%) had previous traumatic open skin wounds. Pre-existing cardiac abnormalities were found in 47 (85%) patients, 28 of whom had valvular abnormalities. Staphylococcus aureus was isolated from the blood as the leading pathogen in 25 (45%) patients (including 23 methicillin-sensitive and 2 methicillin-resistant). Septic emboli and shock occurred in 27 (49%) of 55 patients; surgery was performed on 11 (20%) of those patients, and 4 (36%) of them died post-operatively. The total in-hospital mortality rate was 40% (n = 22). Staphylococcus aureus infection was associated with significantly higher complication and mortality rate than non-Staphylococcus aureus infection (59% vs. 41% and 64% vs. 36%, respectively; p < 0.05). In addition, patients with complications had a very high mortality rate (81.5%). CONCLUSIONS: We found that Staphylococcus aureus was the most common pathogen of IE in Eastern Taiwan, and was associated with higher rates of morbidities and mortality. KEY WORDS: Infective endocarditis; Septic shock; Staphylococcus aureus; Systemic embolization.

Quality improvements of antimicrobial prophylaxis in coronary artery bypass grafting.

BACKGROUND: Although the principles of antibiotics prophylaxis are well established, more than 60% of hospitals that joined the international quality indicator project failed to discontinue the use of prophylactic antibiotics within 24h after coronary artery bypass grafting (CABG). Our specific aims are to disseminate the gain obtained from breakthrough series model in knee arthroplasty and abdominal hysterectomy to increase the rate of prophylactic duration not longer than 24h in patients with CABG. METHODS: The control and intervention groups enrolled 55 and 78 patients with CABG before and after the project. Measurements were prophylactic interval and duration, surgical site infection, hospital and antibiotics costs. Two strategies were developed. The key cardiac surgeon was invited to attend quality improvement activities. Knowledge and rationale of medical quality indicators would thus be communicated. Secondly, we proposed a regional symposium in which a level of competition was subconsciously established, and practitioners would present their level of compliance. RESULTS: Instances of prophylactic interval within 1h prior to incision were significantly increased from 66.7% to 97.4%. Rates of prophylactic duration less than 24h were significantly increased from 2.8% to 66.1%. The average hospital cost was reduced by 16.4%, and antibiotics cost was reduced by 91.8%. No significant changes in surgical site infection within 30 d of CABG were observed. CONCLUSIONS: We successfully disseminated the gain of breakthrough project in improving antimicrobial prophylaxis to CABG. By implementing this model, we are able to optimize the timing and duration of antimicrobial prophylaxis in patients with CABG to a level above worldwide average.

Total arch replacement under normothermic beating heart surgery.

The authors propose a new method for total arch replacement under normothermic beating heart surgery. The surgical procedure was performed with no time limit. The cardiopulmonary bypass was terminated without using inotropic agents. The patient regained consciousness in postoperative hour 8 without any neurologic deficit. This new strategy avoids the potential devastating side-effects associated with deep hypothermic circulatory arrest and myocardial stunning.

Hypoglycemia in a patient with a huge malignant solitary fibrous tumor of the pleura.

Solitary fibrous tumor of the pleura (SFTP) is rare. A 73-year-old man, without past history of diabetes mellitus, was admitted to hospital with profound hypoglycemia, loss of consciousness and respiratory failure. CT indicated a huge heterogenous mass lesion (12 x 12 x 17 cm) at the right thoracic cavity with total atelectasis of the right lower lung. He underwent a standard thoracotomy with complete excision of the tumor. Pathology indicated malignant SFTP with insulin-like growth factor-binding protein-2 production. There were no further incidences of hypoglycemia or respiratory failure after excision of the tumor. Hypoglycemia resulting from a solitary fibrous tumor is uncommon. Standard thoracotomy and complete resection of this giant tumor provided a good result for the present patient.

Cardiac myxoma originating from the anterior mitral leaflet.

Cardiac myxoma arising from the anterior mitral leaflet is extremely rare. A 47-year-old Taiwanese male was found to have a 5 x 4 x 3 cm myxoma originating from the atrial side of the anterior mitral leaflet using transesophageal echocardiography. The tumor was successfully treated by surgical excision. The resected tumor was a well-defined encapsulated mass with a broad-base stalk arising from the anterior mitral leaflet. To detect the early recurrence, a semiannual follow-up examination using transesophageal echocardiography is needed.
