Abstract Introduction Disease-modifying therapies (DMTs) in multiple sclerosis (MS) are chronic therapies, and patients are likely to face challenges in adhering to DMT dosing regimens over time. DMT manufacturers offer patient support programs (PSPs) to increase adherence. PSPs are managed offerings typically encompassing nurse services, phone services, online resources, or mobile offerings. This study evaluated whether PSPs have a...

Abstract During the last 60 years numerous significant attempts have been made to achieve a widely acceptable terminology and histological grading for laryngeal squamous intraepithelial lesions. While dysplasia was included in the pathology of the uterine cervix already in 1953, the term dysplasia was accepted in laryngeal pathology first after the Toronto Centennial Conference on Laryngeal Cancer in 1974. In 1963 Kleinsasser proposed a three-tier classification, and in 1971 Kambic...

Abstract Patients with myeloproliferative neoplasms (MPNs), a group of rare haematological conditions including polycythaemia vera, essential thrombocythaemia, and myelofibrosis, often experience a range of symptoms which can significantly impact their quality of life (QoL). Although symptom burden is highest in myelofibrosis and high-risk patients, lower-risk patients also report symptoms impacting their daily life and ability to work. In addition to physical symptoms, MPNs affect...

Coronary aneurysm located just above the left main coronary artery (LMT) is rare and difficult to treat. How the aneurysm is accessed is very important as it determines the result of the surgery. A 70-year-old man with a large coronary aneurysm (40 mm in diameter) in the LMT underwent surgery to prevent its rupture; however, there was severe adhesion. Initially, dissection of the ascending aorta or the pulmonary artery seemed necessary to access the aneurysm; however, the process was possible with...

A broad set of conditions may present with an exaggerated startle reflex in clinics. This, combined with the overall rarity of these disorders, may pose diagnostic uncertainty in the mind of the treating physician. Herein, we report a case of a patient who presented to us with the complaint of exaggerated startle reflex and outline a simple approach towards characterisation of these disorders.

In patients who experience relapse of multiple myeloma, upwards of 30% can have extramedullary disease. The presence of extramedullary multiple myeloma is typically associated with adverse cytogenetics and a poor prognosis. Organs most commonly involved include the liver, skin, central nervous system, pleural effusions, kidney, lymph nodes, and pancreas. We present the case of a 53-year-old man with IgA kappa multiple myeloma with the adverse cytogenetic findings of t(4;14) and 1q21 gain who had...

Clinical Pathway for Early Diagnosis of COVID-19: Updates from Experience to Evidence-Based Practice
Abstract The COVID-19 pandemic is a significant global event in the history of infectious diseases. The SARS-CoV-2 appears to have originated from bats but is now easily transmissible among humans, primarily through droplet or direct contact. Clinical features of COVID-19 include high fever, cough, and fatigue which may progress to ARDS. Respiratory failure can occur rapidly after this. The primary laboratory findings include lymphopenia and eosinopenia. Elevated D-dimer, procalcitonin,...

Abstract Surface exposed phosphatidylserine (PS) of cancer aids it to evade immune surveillance and thereby results in tumor progression. Earlier, we reported that PS targeting cationic liposomes, phosphatidylcholine–stearylamine (PC-SA), alone and in combination with doxorubicin can result in complete remission of B16F10 melanoma in C57BL/6 mice without signs of toxicity. Inducing an immunogenic response is highly crucial for any cancer therapy as it is essential in improving...

Abstract Emerging mycotoxins produced by Alternaria spp. were previously reported to exert cytotoxic, genotoxic, but also estrogenic effects in human cells. The involved mechanisms are very complex and not fully elucidated yet. Thus, we followed an in silico target fishing approach to extend knowledge on the possible biological targets underlying the activity of alternariol, taken as the signature compound of Alternaria toxins. Combining ligand-based screening and structure-based...

Abstract We previously demonstrated the existence of a balance among steroid hormones, i.e. glucocorticoids and androgens, in RACK1 (receptor for activated C kinase 1) expression and innate immunity activation, which may offer the opportunity to use RACK1 expression as marker to evaluate immunotoxicity of hormone-active substances. Because of the existence of close interconnections between the different steroid hormone receptors with overlapping ligand specificities and signaling...

We have previously demonstrated that ischemia/reperfusion (I/R) impairs endoplasmic reticulum (ER)-based protein folding in the heart and thereby activates an unfolded protein response (UPR) sensor and effector, activated transcription factor 6α (ATF6). ATF6 then induces mesencephalic astrocyte–derived neurotrophic factor (MANF), an ER-resident protein with no known structural homologs and unclear ER function. To determine MANF’s function in the heart in vivo, here we developed a cardiomyocyte-specific...

Sphingosine is a long-chain sphingoid base that has been shown to have bactericidal activity against many pathogens, including Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli. We have previously demonstrated that sphingosine is present in nasal, tracheal, and bronchial epithelial cells and constitutes a central element of the defense of the airways against bacterial pathogens. Here, using assorted lipid-binding and cell biology assays, we demonstrate that exposing P. aeruginosa...

Increased permeability of vascular lung tissues is a hallmark of acute lung injury and is often caused by edemagenic insults resulting in inflammation. Vascular endothelial (VE)-cadherin undergoes internalization in response to inflammatory stimuli and is recycled at cell adhesion junctions during endothelial barrier re-establishment. Here, we hypothesized that phospholipase D (PLD)-generated phosphatidic acid (PA) signaling regulates VE-cadherin recycling and promotes endothelial barrier recovery...

Abstract Feeding difficulties are especially prevalent in preterm infants, although the mechanisms driving these difficulties are poorly understood due to a lack of data on healthy infants. One potential mechanism of dysphagia in adults is correlated with bolus volume. Yet, whether and how bolus volume impacts swallow safety in infant feeding is unknown. A further complication for safe infant swallowing is recurrent laryngeal nerve (RLN) injury due to patent ductus arteriosus...

Abstract Purpose Thyroid hormones (THs) have multiple effects on lipid synthesis, mobilization, and degradation, suggesting that THs may affect the development of dyslipidemia. However, prospective studies on the association between serum THs levels and incident dyslipidemia in euthyroid subjects are limited. Therefore, we conducted a cohort study (~5-year follow-up period, median: 3.0 years) to explore whether THs can affect incident...

This paper describes a framework for understanding military combat mental health based on the possible mental ill-health consequences of exposure to ‘potential trauma events’ for members of the armed forces and after their military service as veterans. It uses a life course approach that maps an individual’s mental well-being against four ‘states’: fit, reacting, injured and ill. It then considers five categories of factors that influence the risk of mental illness from this exposure based on research...

Platelet-derived growth factor receptor-beta (PDGFRβ) is a receptor tyrosine kinase found in cells of mesenchymal origin such as fibroblasts and pericytes. Activation of this receptor is dependent on paracrine ligand induction, and its preferred ligand PDGFB is released by neighboring epithelial and endothelial cells. While expression of both PDGFRβ and PDGFB has been noted in patient breast tumors for decades, how PDGFB-to-PDGFRβ tumor-stromal signaling mediates breast cancer (BC) initiation, progression,...

Abstract Podocyte injury plays a key role in the occurrence and development of kidney diseases. Decreased autophagic activity in podocyte is closely related to its injury and the occurrence of proteinuria. Liver X receptors (LXRs), as metabolic nuclear receptors, participate in multiple pathophysiological processes and express in several tissues, including podocytes. Although the functional roles of LXRs in the liver, adipose tissue and intestine are well established; however,...

Introduction: The diagnosis of GH deficiency (GHD) in adults is based on a reduced GH response to provocative tests, such as the insulin tolerance test (ITT) and the GHRH + arginine (ARG) test. However, the cut-off limits of peak GH response in lean subjects are not reliable in obese patients; this is noteworthy since adult GHD is often associated with obesity. To date there are no cut-offs to ITT related to body mass index (BMI). Objective: Aim of this study was to evaluate the diagnostic cut-offs...

ABSTRACT Central hypogonadism, also defined as hypogonadotropic hypogonadism, is a recognized complication of hypothalamic-pituitary-gonadal axis damage following treatment of sellar and parasellar masses. In addition to radiotherapy and surgery, CTLA4-blocking antibodies and alkylating agents such as temozolomide can also lead to hypogonadism, through different mechanisms. Central hypogonadism in boys and girls may lead to pubertal delay or arrest, impairing full development of the genitalia and...
