Received: 30 October 2020; Accepted: 1 November 2020; Published: 3 November 2020 Keywords: cardiac injury/contractile dysfunction; micronutrient deficiency; macromineral deficiency or imbalance; impact by cardiovascular and/or anti-cancer drugs; systemic inflammation; oxidative/nitrosative stress; antioxidant defenses; supplement and/or pathway interventions Cardiac injury manifested as either systolic or diastolic dysfunction is considered an important preceding stage that leads to or is associated with eventual heart failure (HF). Due to shifts in global age distribution, as well as general population growth, HF is the most rapidly growing public health issue, with an estimated prevalence of approximately 38 million individuals globally, and it is associated with considerably high mortality, morbidity, and hospitalization rates [1]. According to the US Center for Disease Control and The American Heart Association, there were approximately 6.2 million adults suffering from heart failure in the United States from 2013 to 2016, and heart failure was listed on nearly 380,000 death certificates in 2018 [2]. Left ventricular systolic heart failure means that the heart is not contracting well during heartbeats, whereas left ventricular diastolic failure indicates the heart is not able to relax normally between beats. Both types of left-sided heart failure may lead to right-sided failure. There have been an increasing number of studies recognizing that the deficiency and/or imbalance of certain essential micronutrients, vitamins, and macrominerals may be involved in the pathogenesis of cardiomyopathy/cardiac injury/contractile dysfunction. -

We aim to address the black rhino caretaker community at multiple perspectives (keeper, curator, veterinarian, nutritionist, veterinary technician, and researcher) to describe approaches to Iron Overload Disorder in black rhinos and share learnings. This report includes sections on (1) background on how iron functions in comparative species and how Iron Overload Disorder appears to work in black rhinos, (2) practical recommendations for known diagnostics, (3) a brief review of current investigations on inflammatory and other potential biomarkers, (4) nutrition knowledge and advice as prevention, and (5) an overview of treatment options including information on chelation and details on performing large volume voluntary phlebotomy. The aim is to use evidence to support the successful management of this disorder to ensure optimal animal health, welfare, and longevity for a sustainable black rhinoceros population. Abstract: Critically endangered black rhinoceros (BR) under human care are predisposed to non-hemochromatosis Iron Overload Disorder (IOD). -

Clinical Characteristics of Tumor Lysis Syndrome in Childhood Acute Lymphoblastic Leukemia

The clinical features, therapeutic regimens, and outcomes of TLS have not been comprehensively analyzed in Chinese children with ALL. A total of 5537 children with ALL were recruited from the Chinese Children’s Cancer Group, including 79 diagnosed with TLS. The clinical characteristics, treatment regimens, and survival of TLS patients were analyzed. Age distribution of children with TLS was remarkably diferent from those without TLS. White blood cells (WBC) count ≥ 50 × 109/L was associated with a higher risk of TLS [odds ratio (OR) = 2.6, 95% CI = 1.6–4.5]. The incidence of T-ALL in TLS children was signifcantly higher than that in non-TLS controls (OR = 4.7, 95% CI = 2.6–8.8). Hyperphosphatemia and hypocalcemia were more common in TLS children with hyperleukocytosis (OR = 2.6, 95% CI = 1.0–6.9 and OR = 5.4, 95% CI = 2.0–14.2, respectively). Signifcant diferences in levels of potassium (P = 0.004), calcium (P < 0.001), phosphorus (P < 0.001) and uric acid (P < 0.001) were observed between groups of TLS patients with and without increased creatinine. -

A Short Review of Iron Metabolism and Pathophysiology of Iron Disorders
medicines Review A Short Review of Iron Metabolism and Pathophysiology of Iron Disorders Andronicos Yiannikourides 1 and Gladys O. Latunde-Dada 2,* 1 Faculty of Life Sciences and Medicine, Henriette Raphael House Guy’s Campus King’s College London, London SE1 1UL, UK 2 Department of Nutritional Sciences, School of Life Course Sciences, King’s College London, Franklin-Wilkins-Building, 150 Stamford Street, London SE1 9NH, UK * Correspondence: [email protected] Received: 30 June 2019; Accepted: 2 August 2019; Published: 5 August 2019 Abstract: Iron is a vital trace element for humans, as it plays a crucial role in oxygen transport, oxidative metabolism, cellular proliferation, and many catalytic reactions. To be beneficial, the amount of iron in the human body needs to be maintained within the ideal range. Iron metabolism is one of the most complex processes involving many organs and tissues, the interaction of which is critical for iron homeostasis. No active mechanism for iron excretion exists. Therefore, the amount of iron absorbed by the intestine is tightly controlled to balance the daily losses. The bone marrow is the prime iron consumer in the body, being the site for erythropoiesis, while the reticuloendothelial system is responsible for iron recycling through erythrocyte phagocytosis. The liver has important synthetic, storing, and regulatory functions in iron homeostasis. Among the numerous proteins involved in iron metabolism, hepcidin is a liver-derived peptide hormone, which is the master regulator of iron metabolism. This hormone acts in many target tissues and regulates systemic iron levels through a negative feedback mechanism. Hepcidin synthesis is controlled by several factors such as iron levels, anaemia, infection, inflammation, and erythropoietic activity.
