Emerging Role of Large-bore Percutaneous Axillary Vascular Access: A Step-by-step Guide.

Interv Cardiol 2020 Apr 15;15:e07. Epub 2020 Jun 15.

Division of Cardiology, Department of Medicine, University of Washington Heart Institute Seattle, WA, US.

Advances in transcatheter structural heart interventions and temporary mechanical circulatory support have led to increased demand for alternative sites for large-bore vascular access. Percutaneous axillary artery access is an appealing alternative to femoral access in patients with peripheral arterial disease, obesity or for prolonged haemodynamic support where patient mobilisation may be valuable. In particular, axillary access for mechanical circulatory support allows for increased mobility while using the device, facilitating physical therapy and reducing morbidity associated with prolonged bed rest.

Peripheral and Central Nervous System Immune Response Crosstalk in Amyotrophic Lateral Sclerosis.

Front Neurosci 2020 16;14:575. Epub 2020 Jun 16.

Department of Neurology, The First Hospital of China Medical University, Shenyang, China.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by muscle weakness due to the degeneration of the upper and lower motor neurons. Neuroinflammation is known as a prominent pathological feature of ALS. Although neuroinflammation cannot trigger ALS, activated central nervous system (CNS) microglia and astrocytes, proinflammatory periphery monocytes/macrophages and T lymphocytes, and infiltrated monocytes/macrophages and T lymphocytes, as well as the immunoreactive molecules they release, are closely related to disease progression.

The Red Color of Life Transformed - Synthetic Advances and Emerging Applications of Protoporphyrin IX in Chemical Biology.

European J Org Chem 2020 Jun 30;2020(22):3171-3191. Epub 2020 Mar 30.

School of Chemistry Trinity College Dublin The University of Dublin Trinity Biomedical Sciences Institute 152-160 Pearse Street 2 Dublin Ireland.

Protoporphyrin IX (PPIX) is the porphyrin scaffold of heme b, a ubiquitous prosthetic group of proteins responsible for oxygen binding (hemoglobin, myoglobin), electron transfer (cytochrome c) and catalysis (cytochrome P450, catalases, peroxidases). PPIX and its metallated derivatives frequently find application as therapeutic agents, imaging tools, catalysts, sensors and in light harvesting. The vast toolkit of accessible porphyrin functionalization reactions enables easy synthetic modification of PPIX to meet the requirements for its multiple uses. Read More

The history and advances in cancer immunotherapy: understanding the characteristics of tumor-infiltrating immune cells and their therapeutic implications.

Cell Mol Immunol 2020 Jul 1. Epub 2020 Jul 1.

Beijing Advanced Innovation Center for Genomics, Peking-Tsinghua Center for Life Sciences, Academy for Advanced Interdisciplinary Studies, Peking University, 100871, Beijing, China.

Immunotherapy has revolutionized cancer treatment and rejuvenated the field of tumor immunology. Several types of immunotherapy, including adoptive cell transfer (ACT) and immune checkpoint inhibitors (ICIs), have obtained durable clinical responses, but their efficacies vary, and only subsets of cancer patients can benefit from them. Immune infiltrates in the tumor microenvironment (TME) have been shown to play a key role in tumor development and will affect the clinical outcomes of cancer patients. Read More

[RyR2 mutation-linked arrhythmogenic diseases and its therapeutic strategies].

Nihon Yakurigaku Zasshi 2020 ;155(4):225-229

Department of Cellular and Molecular Pharmacology, Juntendo University, Graduate School of Medicine.

The type 2 ryanodine receptor (RyR2) is a sarcoplasmic reticulum Ca release channel that plays a central role in cardiac excitation-contraction coupling. Abnormal activity of the RyR2 is linked to abnormal Ca signaling in cardiac cells, which often results in cardiac arrhythmias. For example, amino acid mutations in RyR2 have been reported to cause various types of arrhythmias, including catecholaminergic polymorphic ventricular tachycardia (CPVT), idiopathic ventricular fibrillation, and left ventricular non-compaction.

In 2016, the Rome criteria were updated as Rome IV, and only minor changes were introduced for functional dyspepsia (FD). The major symptoms of FD now include not only postprandial fullness, but also epigastric pain and burning, and early satiation at above the "bothersome" level. Investigations into the effect of meal ingestion on symptom generation have indicated that not only postprandial fullness and early satiety but also epigastric pain and burning sensation and nausea (not vomiting) may increase after meals.

Sellar Pathologies Mimicking Pituitary Tumors.

Neurol India 2020 May-Jun;68(Supplement):S154-S160

Department of Neurosurgery, Bombay Hospital Institute of Medical Sciences, Mumbai, Maharashtra, India.

The most common sellar pathology that merits neurosurgical attention is the pituitary adenoma. However, some developmental, inflammatory, and neoplastic lesions may primarily or secondarily involve the sella, mimicking pituitary tumors. Advances in imaging and endocrinological assessment have helped in the recognition of these less common sellar, supra sellar pathologies, which may occasionally create confusion in management.

Modern Radiation Therapy for Pituitary Adenoma: Review of Techniques and Outcomes.

Neurol India 2020 May-Jun;68(Supplement):S113-S122

Department of Radiation Oncology; Department of Neuro-Oncology Disease Management Group, TMH/ACTREC, Tata Memorial Centre, Homi Bhabha National Institute (HBNI), Mumbai, Maharashtra, India.

Pituitary adenomas are benign tumors arising in the adenohypophysis and comprise 8%-20% of all reported primary brain tumors in the west. Transsphenoidal surgery with an aim to achieve complete tumor resection is the recommended first-line treatment for nonfunctioning as well as secretory pituitary adenoma. External beam radiation therapy (RT) has been demonstrated to be an effective treatment modality for pituitary adenoma, uncured by surgery and/or medical therapy, providing excellent long-term local control (>90%), but lower and variable rates (50%-80%) of biochemical remission in secretory tumors.

Endocrinological Management of Sellar and Supra-Sellar Tumors in Children.

Neurol India 2020 May-Jun;68(Supplement):S28-S32

Clinical and Research Fellow, Pediatric Endocrinology, Jehangir Hospital, Pune, Maharashtra, India.

CNS tumours and their treatment commonly lead to endocrinopathies in children. Advances in surgical techniques, chemotherapy and radiotherapy have improved the survival in children with CNS tumours however they have also added to the late effect burden. Since the pituitary and hypothalamus regulate many important bodily functions, loss in their function leads to major derangements in growth and hormonal milieu. Read More

Current Status of Diagnosis and Management for Functioning Pituitary Tumors: Part I.

Neurol India 2020 May-Jun;68(Supplement):S13-S19

Department of Endocrinology, Seth G.S. Medical College and KEM Hospital, Mumbai, Maharashtra, India.

Pituitary adenomas (PA) account for approximately 15% of all intracranial neoplasms. Pituitary adenomas can be of different subtypes based on the cell of origin or associated hormone hypersecretion (non-functioning pituitary adenoma, prolactinoma, somatotropinoma, corticotropinoma, thyrotropinoma, and gonadotropinoma). Functioning PAs are associated with relatively higher morbidity and mortality because of associated hormone hypersecretion syndromes. Read More
