Integrated heart and lung multimodality imaging plays a central role in different clinical settings and is essential in the diagnosis, risk stratification, and management of patients with COVID-19. The aims of this review are to summarize imaging-oriented pathophysiological mechanisms of lung and cardiac involvement in COVID-19 and to provide a guide for integrated imaging assessment in these patients.

The authors present a method that focuses on cohort matching algorithms for performing patient-to-patient comparisons along multiple echocardiographic parameters for predicting meaningful patient subgroups.

Recent efforts in collecting multiomics data open numerous opportunities for comprehensive integration of highly heterogenous data to classify a patient's cardiovascular state, eventually leading to tailored therapies.

A total of 42 echocardiography features, including 2-dimensional and Doppler measurements, left ventricular (LV) and atrial speckle-tracking, and vector flow mapping data, were obtained in 297 patients. A similarity network was developed to delineate distinct patient phenotypes, and then neural network models were trained for discriminating the phenotypic presentations.

The patient similarity model identified 4 clusters (I to IV), with patients in each cluster showed distinctive clinical presentations based on American College of Cardiology/American Heart Association heart failure stardiac phenogroups in terms of clinical characteristics, cardiac structure and function, hemodynamics, and outcomes.

Recent studies report incongruent finds regarding the addition of pegylated interferon -alpha (Peg- IFNα) to nucleos(t)ide analogues. This study was designed to compare the efficacy of Peg- IFNα and tenofovir disoproxil fumarate (TDF) combination therapy with each of the treatments separately.

In this open-label, randomized clinical trial, treatment-naive hepatitis B e antigen (HBeAg)-negative patients were randomly assigned to three treatment groups Group A Peg- IFNα (180 mcg/week) with TDF (300mg/day); Group B TDF (300mg/day); and Group C Peg- IFNα (180 mcg/week). The intervention spanned 48 weeks and patients were followed up every 12 weeks. The primary end-point was HBV DNA load <20 IU/mL.

Groups A, B and C each comprised of 22, 23 and 22 patients, respectively. The number of patients with HBV DNA suppression in group A was significantly higher compared to groups B and C (P=0.034). No significant difference was observed in the normalization trends of serum ALT levels between the three groups (P=0.082). At week 48, combination therapy was significantly more effective in suppressing HBV DNA concentration to below the level of detection than TDF monotherapy (OR=2.1, 95%CI 1.18-4.15; P=0.034). Furthermore, a comparison between monotherapy arms revealed that both interventions had similar effects on the overall outcome (OR=1.24, 95%CI 1.02-5.8; P=0.062).

A Peg- IFNα and TDF combination therapy resulted in improved virologic response and was safe in HBeAg negative patients. BRM/BRG1 ATP Inhibitor-1 solubility dmso with Peg-IFNα or TDF procured limited benefits in comparison.

Improvements in surgical technique and anesthetic and perioperative care have significantly increased the number of survivors. Unfortunately, as these patients progress through life they frequently require further interventions. Although surgical intervention may be required frequently, these patients can be managed in the cardiac catheterization or electrophysiology laboratory. Surgical correction of tetralogy of Fallot can leave patients with pulmonary valve dysfunction later in life. A percutaneous approach is now available for these patients, which can obviate the need for resternotomy. During deployment of the valve, anesthesiologists should be aware that compression of coronary arteries can occur. Adult congenital heart disease (ACHD) patients often require pacemaker/implantable cardioverter- defibrillator (ICD) insertion or ablation therapy. These patients may have altered cardiac anatomy, which can make endovascular procedures extremely challenging. Recent developments have made these procedures safer and more efficient. #link# A number of congenital cardiac conditions can also be associated with orofacial abnormalities. ACHD patients, as a result, can present with challenging airways. The catheterization laboratory may not be the optimum environment for the anesthesiologist to manage a difficult airway. The requirement of transesophageal echocardiography for some cath eterization procedures needs to be considered when deciding on an airway management plan. Knowledge of the underlying cardiac anatomy and the planned procedure is advised when providing anesthesia for this complex patient group outside the theater setting.

The authors aimed to investigate if the anesthetic technique was associated with 3-year all-cause mortality after isolated coronary artery bypass grafting (CABG).

Population-based cohort study.

Cohort data obtained from the National Health Insurance Service database in South Korea.

All adult patients diagnosed with ischemic heart disease who underwent isolated CABG between January 2012 and December 2015.

The authors divided the cohort into the following 2 groups the total intravenous anesthesia group using propofol (TIVA group) and the volatile anesthesia group.

The primary study endpoint was 3-year all-cause mortality. The authors enrolled 10,440 patients from 91 hospitals; among them, 3,967 patients were in the TIVA group and 6,473 were in the volatile anesthesia group. After propensity score matching, the authors included 5,656 patients (2,828 patients per group) in the final analysis. The 3-year all-cause mortality rates in the TIVA and volatile anesthesia groups were 15.3% (434/2,828) and 18.3% (518/2,828), respectively. The risk of 3-year all-cause mortality was 16% lower in the TIVA group than in the volatile anesthesia group (hazard ratio 0.84, 95% confidence interval 0.75-0.94; p = 0.002). Similar results were observed for 30-day, 90-day, and 1-year all-cause mortality after CABG.

Compared with volatile anesthesia, propofol-based TIVA was associated with decreased 3-year all-cause mortality in patients undergoing CABG. link2 This was the first study to suggest that TIVA might be associated with an increase in survival at 3-year follow-up after CABG, and further studies are needed to confirm the optimal anesthetic choice for CABG.

Chronic kidney disease (CKD) is a risk factor for contrast associated acute kidney injury (CA-AKI). link3 The risk of renin-angiotensin-aldosterone system inhibitor (RASi) use in patients with CKD before the administration of contrast is not clear.

In this nested case-control study, 8668 patients received contrast computed tomography (CT) from 2013 to 2018 during index administration in a multicenter hospital cohort. The identification of AKI is based on the Kidney Disease Improving Global Outcomes (KDIGO) serum creatinine criteria within 48h after contrast medium used.

Finally, 986 patients (age, 63.36±12.22; men, 72.92%) with CKD (estimated glomerular filtration rate (eGFR)=35.0±19.8mL/min/1.73m

) were eligible for analysis. After the index date, RASi users (n=315) were less likely to develop CA-AKI (13.65% vs 30.4%, p<0.001), and had a lower hospital mortality (8.25% vs 19.23%, p<0.001) compared with non-users. The pre-contrast use of RASi decrease the risk of AKI (OR, 0.342, p<0.001) and hospital mortality (OR, 0.602, p=0.045). Even a few defined daily doses (DDDs) of RASi treatment, more than 0.02 prior to contrast CT could attenuate CA-AKI. The hospital mortality was higher in RASi non-users if their eGFR value was more than 17.9mL/min/1.73m

.

RASi use in patients with CKD prior to contrast CT has the potential to mitigate the incidence of AKI and hospital mortality. Even a low dose of RASi will noticeably decrease the risk of AKI and will not increase the risk of hyperkalemia.

RBFOX2, an RNA-binding protein, controls tissue-specific alternative splicing of exons in diverse processes of development. The progenitor cytotrophoblast of the human placenta differentiates into either the syncytiotrophoblast, formed via cell fusion, or the invasive extravillous trophoblast lineage. The placenta affords a singular system where a role for RBFOX2 in both cell invasion and cell fusion may be studied. We investigated a role for RBFOX2 in trophoblast cell differentiation, as a foundation for investigations of RBFOX2 in embryo implantation and placental development.

Immunohistochemistry of RBFOX2 was performed on placental tissue sections from three trimesters of pregnancy and from pathological pregnancies. Primary trophoblast cell culture and immunofluorescence were employed to determine RBFOX2 expression upon cell fusion. Knockdown of RBFOX2 expression was performed with βhCG and syncytin-1 as molecular indicators of fusion.

In both normal and pathological placentas, RBFOX2 expression wasplacental development, yielding possible insights into preeclampsia, where expression of antiangiogenic isoforms produced through alternative splicing play a critical role in disease development and severity.

Laparoscopic cholecystectomy has reached nearly universal adoption in the management of gallstone-related disease. With advances in operative technology, robotic-assisted cholecystectomy has been used increasingly in many practices, but few studies have examined the adoption of robotic assistance for inpatient cholecystectomy and the temporal outcomes on a national scale. The present study aimed to identify trends in utilization, as well as outcomes and factors associated with the use of robotic-assisted cholecystectomy.

The 2008 to 2017 database of the National Inpatient Sample was used to identify patients undergoing inpatient cholecystectomy. Independent predictors of the use of robotic assistance for cholecystectomy were identified using multivariable logistic regression adjusting for patient and hospital characteristics.

Of an estimated 3,193,697 patients undergoing cholecystectomy, 98.7% underwent laparoscopic cholecystectomy and 1.3% robotic-assisted cholecystectomy. Rates of robotic-assisted choic increase in the use of robotic-assisted cholecystectomy with no difference in mortality or duration of hospital stay, but there was a statistically significant increase in complications and costs. These findings warrant further investigation.
