Congenital heart disease (CHD) is the most common type of birth defect. Without timely detection and treatment, approximately one-third of children with CHD would die in the infant period. However, due to the complicated heart structures, early diagnosis of CHD and its types is quite challenging, even for experienced radiologists. Here, we present an artificial intelligence (AI) system that achieves a comparable performance of human experts in the critical task of classifying 17 categories of CHD types. We collected the first-large CT dataset from three different CT machines, including more than 3750 CHD patients over 14 years...

OBJECTIVE: To explore how patients, community-based perinatal support professionals, and health system clinicians and staff perceived facilitators and barriers to implementation of a randomized clinical trial (RCT) designed to optimize Black maternal heart health. METHODS: This article describes the formative work that we believed needed to occur before the start of the Change of H.E.A.R.T (Here for Equity, Advocacy, Reflection and Transformation) RCT. We used a qualitative, descriptive design and community-based, participatory approach, the latter of which allowed our team to intentionally focus on avoiding harm and equalizing power dynamics throughout the research process...

BACKGROUND: Phosphodiesterase inhibitors are known to relieve symptoms in the setting of heart failure, although their effects in restrictive ventricular physiology have been poorly characterized. We explored the association between the use of milrinone and volume administration during the first 72 hours following surgical repair of tetralogy of Fallot (TOF). METHODS: We reviewed all cases of primary surgical repair of TOF with pulmonary stenosis or atresia at Boston Children's Hospital between 2011 and 2020...

BACKGROUND: There are little long-term health data, particularly in terms of body composition and development of metabolic syndromes, to help surgeons to guide the decision between limb salvage and amputation in patients with limb-threatening trauma. The purpose of this study was to compare long-term health outcomes after high-energy lower-extremity trauma between patients who underwent attempted flap-based limb salvage or amputation. METHODS: We performed a retrospective review of servicemembers with a minimum 10-year follow-up who underwent flap-based limb salvage followed by unilateral amputation or continued limb salvage after combat-related, lower-extremity trauma between 2005 and 2011...

AIMS: Glycemic variability has been suggested as a risk factor for diabetes complications but the precise deleterious mechanisms remain poorly understood. Since mitochondria are the main source of energy in heart and cardiovascular diseases remain the first cause of death in patients with diabetes, the aim of the study was to evaluate the impact of glucose swings on mitochondrial functions in the cardiomyocyte cell line HL-1. METHODS: HL-1 cells were exposed to low (LG, 2...

The beta-adrenergic system is a potent stimulus for enhancing cardiac output that may become deleterious when energy metabolism is compromised as in heart failure. We thus examined whether the AMP-activated protein kinase (AMPK) that is activated in response to energy depletion may control the beta-adrenergic pathway. We studied the cardiac response to beta-adrenergic stimulation of AMPKα2-/- mice or to pharmacological AMPK activation on contractile function, calcium current, cAMP content and expression of adenylyl cyclase 5 (AC5), a rate limiting step of the beta-adrenergic pathway...

BACKGROUND: Cardiac transplantation requires lifelong immunosuppressant medications to prevent rejection. However, some patients may not tolerate multiple immunosuppressants due to adverse effects. At our institution, patients may be converted to monotherapy with tacrolimus if unable to tolerate a combination regimen. This study evaluated the outcomes among patients converted to tacrolimus monotherapy compared with those maintained on combination immunosuppression. METHODS: This single-center, retrospective cohort study included patients who received heart transplants at Sentara Norfolk General Hospital between January 2015 and July 2021...

Hibernating mammals are natural models of resistance to ischemia, hypoxia-reperfusion injury, and hypothermia. Daurian ground squirrels (spermophilus dauricus) can adapt to endure multiple torpor-arousal cycles without sustaining cardiac damage. However, the molecular regulatory mechanisms that underlie this adaptive response are not yet fully understood. This study investigates morphological, functional, genetic, and metabolic changes that occur in the heart of ground squirrels in three groups: summer active (SA), late torpor (LT), and interbout arousal (IBA)...

The Foot-and-Mouth disease is highly contagious acute viral disease of livestock inflicting huge economic loss to the farmers. The limited knowledge regarding the pathological lesions vis-a-vis distribution of the FMDV in in lesser explored endocrine glands and important vital organs other than the target organs of infected calves prompted us to take the present investigation to have detailed insight into the pathogenesis. The systematic necropsy of 37 dead calves (cattle-28 and buffalo-9) was conducted, and thin representative tissue pieces from the affected organs were collected in 10% neutral buffered formalin (NBF) for pathological and immunohistochemical investigations...

Manual handling of chickens is required for many veterinary, research, and breeding procedures. This study aimed to assess the changes in physiological parameters over time during manual restraint of chickens, as well as the effect of hooding on these parameters. Heart rate, heart rate variability, respiratory rate, and body temperature were measured every 3 minutes for 15 minutes during manual restraint in 13 adult laying hens ( Gallus gallus domesticus ). Heart rate variability was significantly higher in hooded hens than in nonhooded hens ( P = 0...

Backyard poultry hens are becoming very popular as pets, and thus the demand for treating the individual chicken is increasing. Few basic diagnostic techniques commonly used in small animal practice have been evaluated in this species. At the moment, there is no study in backyard hens describing radiographic measurements of internal organs contrary to psittacine birds or birds of prey. Moreover, the effect of egg laying on these measurements has not been studied in avian species even though it could affect radiographic measurements depending on the stage of egg formation...

Adhesives with robust but readily detachable wet tissue adhesion are of great significance for wound closure. Polyelectrolyte complex adhesive (PECA) is an important wet tissue adhesive. However, its relatively weak cohesive and adhesive strength cannot satisfy clinical applications. Herein, modified tannic acid (mTA) with a catechol group, a long alkyl hydrophobic chain, and a phenyl group was prepared first, and then, it was mixed with acrylic acid (AA) and polyethylenimine (PEI), followed by UV photopolymerization to make a wet tissue adhesive hydrogel with tough cohesion and adhesion strength...

BACKGROUND: Estimated plasma volume status (ePVS) is a marker of intravascular congestion and has prognostic value in patients with heart failure (HF). The elevation of intracardiac filling pressures is defined as hemodynamic congestion and is also associated with poor prognosis. However, the relationship between intravascular congestion and hemodynamic congestion remains unclear. This study sought to explore the correlation between ePVS and hemodynamic parameters and determine the association between ePVS and clinical outcomes in patients with advanced HF...

PURPOSE OF REVIEW: The purpose of this review is to analyze the link between testosterone replacement therapy (TRT) and adverse cardiovascular (CV) events. RECENT FINDINGS: A few published studies suggest a link between TRT and CV events. These studies contained flaws, and many other studies reveal a reduction in CV events. Hypogonadism is associated with increased mortality in men with CVD. TRT in hypogonadal men can improve many CVD risk factors, reduce QT interval prolongation, lead to better outcomes in heart failure patients, and slow the progression of atherosclerosis...
