Background: Surgical ventricular reconstruction (SVR) has been used to control adverse ventricular remodeling and improve cardiac function in ischemic cardiomyopathy. The purpose of this systematic review and meta-analysis was to collect and analyze all available evidence on the utilization and efficacy of SVR.Methods: An electronic database search was performed to identify all retrospective and prospective studies on SVR for ischemic cardiomyopathy in the English literature from 2000 through 2020. A total of 92 articles with a collective 7,685 patients undergoing SVR were included in the final analysis.Results: The mean patient age was 61 years (95% CI: 59-63) and 80% (78-82%) were male. Congestive heart failure was present in 66% (54-78%) and angina in 58% (45-70%). Concomitant coronary artery bypass grafting was undertaken in 92% (90-93%) while 21% (18-24%) underwent mitral valve repair. Pre vs. post-SVR, significant improvement was seen in left ventricular ejection fraction (LVEF) [29.9% (28.8-31.2%) vs. 40.9% (39.4-42.4%), P<0.01], left ventricular end-systolic (LVESD) and end-diastolic diameters (LVEDD)
Majority cases of neonatal sepsis have got electrolyte abnormalities. Hyperkalemia was the commonest electrolyte imbalance followed by hypercalcemia and hypocalcemia.
Background: Bronchial artery revascularization (BAR) during lung transplantation has been hypothesized to improve early tracheal healing and delay the onset of bronchiolitis obliterans syndrome (BOS). We aimed to assess the outcomes of BAR after lung transplantation.Methods: Electronic search in Ovid Medline, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Scopus, and Cochrane Controlled Trials Register (CCTR) databases was performed to identify all relevant studies published about lung transplantation with BAR. Studies discussing lung transplantation utilizing BAR were included while those without outcome data such as BOS and survival were excluded.Cohort-level data were extracted and pooled for analysis. A binary outcome meta-analysis of proportions with logit transformation was conducted. Newcastle-Ottawa scale was used for risk of bias assessment.Results: Seven studies were selected for the analysis comprising 143 patients. Mean patient age was 47 (95% CI: 40-55) years. 61% (48-72%) were male. 73% (65-79%) of patients underwent double lung transplant while 27% (21-25%) underwent single lung transplant. In patients with postoperative angiography, successful BAR was demonstrated in 93% (82-97%) of all assessed conduits. The 30-day/in-hospital mortality was 6% (3-11%). 79% (63-89%) of patients were free from rejection at three months. 83% (29-98%) of patients were free from signs of airway ischemia at three and six months. Pooled survival at one year and five years was 87% (78-92%) and 71% (46-87%), respectively, with a mean follow-up time of 21 (3-38) months. Pooled freedom from bronchiolitis obliterans was 86% (77-91%) at two years.Conclusions: While this systematic review and meta-analysis is limited by the available surgeons, institutions, and papers discussing a highly specialized technique, it does show that BAR is a viable technique to minimize BOS and early anastomotic intervention following lung transplantation.
Introduction: Extracorporeal carbon dioxide removal (ECCO 2 R) provides respiratory support to patients suffering from hypercapnic respiratory failure by utilizing an extracorporeal shunt and gas exchange membrane to remove CO 2 from either the venous (VV-ECCO 2 R) or arterial (AV-ECCO 2 R) system before return into the venous site. AV-ECCO 2 R relies on the patient's native cardiac function to generate pressures needed to deliver blood through the extracorporeal circuit.VV-ECCO 2 R utilizes a mechanical pump and can be used to treat patients with inadequate native cardiac function. We sought to evaluate the existing evidence comparing the subgroups of patients supported on VV and AV-ECCO 2 R devices.
Methods: A literature search was performed to identify all relevant studies published between 2000 and 2019. Demographic information, medical indications, perioperative variables, and clinical outcomes were extracted for systematic review and meta-analysis. Results: Twenty-five studies including 826 patients were reviewed. 60% of patients (497/826) were supported on VV-ECCO 2 R. The most frequent indications were acute respiratory distress syndrome (ARDS) [69%, (95%CI: 53%-82%)] and chronic obstructive pulmonary disease (COPD) [49%, (95%CI: 37%-60%)]. ICU length of stay was significantly shorter in patients supported on VV-ECCO 2 R compared to AV-ECCO 2 R [15 (95%CI: 7-23) vs. 42 (95%CI: 17-67) days, p = 0.05].In-hospital mortality was not significantly different [27% (95%CI: 18%-38%) vs. 36% (95%CI: 24%-51%), p = 0.26].
Conclusion:Both VV and AV-ECCO 2 R provided clinically meaningful CO 2 removal with comparable mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
