Transcatheter pulmonary valve implantation with custom-made 35-mm Myval™ transcatheter heart valve.

Transcatheter pulmonary valve implantation (TPVI) is the standard of care in patients with repaired tetralogy of Fallot (rTOF) presenting with right ventricular outflow tract (RVOT) dysfunction. However, the feasibility of TPVI is limited by the high cost and nonavailability of larger-sized valves for dilated native RVOT of rTOF patients. We report the first successful TPVI with a custom-made 35 mm balloon-expandable valve (Myval™) in a 30-year-old rTOF patient with severe pulmonary regurgitation and RV dysfunction.

Clarifying the Anatomy of Tetralogy of Fallot with S-shaped Ascending Aorta.

We recently encountered several cases of tetralogy of Fallot with an abnormally oriented S-shaped ascending aorta. In this retrospective study, we sought to clarify morphology of this unusual under-recognized variant. Databases were reviewed to identify all patients with tetralogy of Fallot having an S-shaped ascending aorta.

Immunomodulation by juglone alleviates acute graft-versus-host disease without compromising the graft-versus-leukaemia activity in mice.

Background And Purpose: Acute graft-versus-host disease (GVHD) remains a major barrier to successful transplantation outcomes. Recent studies have shown that pharmacotherapy for GVHD should target both the innate and adaptive inflammatory immune responses. Juglone, a redox-active phytochemical found in walnuts, has shown potent anti-inflammatory effects in models of colitis and inflammatory bowel disease.

Preclinical evaluation of engineered L-asparaginase variants to improve the treatment of Acute Lymphoblastic Leukemia.

Introduction: Escherichia coli l-asparaginase (EcA), an integral part of multi-agent chemotherapy protocols of acute lymphoblastic leukemia (ALL), is constrained by safety concerns and the development of anti-asparaginase antibodies. Novel variants with better pharmacological properties are desirable.

Methods: Thousands of novel EcA variants were constructed using protein engineering approach.

Understanding the diabetes self-care behaviour in rural areas: Perspective of patients with type 2 diabetes mellitus and healthcare professionals.

Background: Diabetes self-care behaviour plays a crucial role in managing the diabetes effectively and preventing complications. Patients with type 2 diabetes mellitus (T2DM) and health care professionals (HCPs) of rural areas often face unique challenges when it comes to diabetes self-care practices (SCPs). Therefore, this study aim to explore the perspectives of patients with T2DM and HCPs on diabetes SCPs.

Extract Mitigates Experimental Acute Graft versus Host Disease Without Abrogating Graft Versus Leukemia Effect.

Acute graft versus host disease (aGvHD) is the major contributor of nonrelapse mortality in alloHSCT. It is associated with an inflammatory immune response manifesting as cytokine storm with ensuing damage to target organs such as liver, gut, and skin. Prevention of aGvHD while retaining the beneficial graft versus leukemia (GvL) effect remains a major challenge.

Comparative evaluation of divergent concoction of NGF, BDNF, EGF, and FGF growth factor's role in enhancing neuronal differentiation of adipose-derived mesenchymal stem cells.

MSCs (Mesenchymal Stem Cells) can differentiate into various lineages, including neurons and glial cells. In the past few decades, MSCs have been well explored in the context of neuronal differentiation and have been reported to have the immense potential to form distinct kinds of neurons. The distinguishing features of MSCs make them among the most desired cell sources for stem cell therapy.

Reciprocal impulses of junctional origin causing trigeminy.

Reciprocal impulses of junctional origin were seen in a patient with left isomerism who had undergone Kawashima repair in infancy. Heterotaxy syndromes are associated with disturbances in sinus node function. Junctional rhythm is hence common in this group.

Mitocurcumin utilizes oxidative stress to upregulate JNK/p38 signaling and overcomes Cytarabine resistance in acute myeloid leukemia.

Acute myeloid leukemia (AML) is a type of blood cancer that is characterized by the rapid growth of abnormal myeloid cells. The goal of AML treatment is to eliminate the leukemic blasts, which is accomplished through intensive chemotherapy. Cytarabine is a key component of the standard induction chemotherapy regimen for AML.

Recanalized vein of marshall following bidirectional glenn surgery.

A 6-year-old boy with a case of double outlet right ventricle with large non-routable ventricle septal defect and severe pulmonary stenosis was deemed unsuitable for biventricular repair on a prior evaluation. Hence, a bidirectional Glenn (BDG) shunt was performed at 3 years of age following cardiac catheterization.

COVID-19 associated renal artery stenosis in infancy - A report of two cases.

Organ-specific vasculitis is an uncommon, delayed complication of COVID-19 infection. It is usually seen in mildly symptomatic or asymptomatic patients. Underlying endothelitis is the most likely pathophysiological mechanism for such a manifestation.

Potential Use of Nucleic Acids as a Preceramic Polymer to Synthesize Nanodiamond-Embedded Phosphate Glass for Hard Tissue Engineering.

In recent years, nucleic acid has emerged as a versatile molecule that has been strategically used in material synthesis and biomedical applications. Keeping in mind the presence of the phosphate group, a glass former in the nucleic acids, we synthesized a transparent glass-like material by the thermal treatment of nucleic acids (DNA and RNA) at 900 °C at atmospheric pressure. Characterization of this material by transmission electron microscopy, X-ray photoelectron spectroscopy, and confocal fluorescence microscopy suggested the presence of in situ-formed nanodiamonds within the phosphate glass matrix.

Kawasaki disease or polyarteritis nodosa: coronary involvement, a diagnostic conundrum.

Polyarteritis nodosa (PAN) is a medium-vessel vasculitis presenting with cutaneous and multisystem involvement with considerable morbidity. The necrotizing vasculitis in PAN typically involves renal, celiac, and mesenteric vascular beds. Coronary artery involvement is a characteristic feature of Kawasaki disease, another medium-vessel vasculitis; however, it has been rarely reported with PAN.

Withaferin-A alleviates acute graft versus host disease without compromising graft versus leukemia effect.

Acute graft versus host disease (aGvHD) contributes to a significant proportion of non-relapse mortality and morbidity in patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT). Withaferin-A (WA), a phytomolecule obtained from Withania somnifera (Ashwagandha), is known to have anti-inflammatory, anti-proliferative and immunomodulatory properties. The efficacy of WA for the prevention and treatment of aGvHD was evaluated using a murine model of alloHSCT.

Successful balloon dilatation of an infolded polytetrafluoroethylene graft: An unusual cause of early Fontan failure.

Despite optimal medical management, an 8-year-old boy had persistent pleural drainage following total cavopulmonary connection. Detailed evaluation, including computed tomography angiography, confirmed obstruction at the lower end of the circuit due to infolding of the polytetrafluoroethylene graft. Balloon dilation of the obstruction resulted in prompt resolution of pleural effusion with sustained relief at 1-year follow-up.
