Risk Factors and Outcomes of Rapid Correction of Severe Hyponatremia
Article Risk Factors and Outcomes of Rapid Correction of Severe Hyponatremia Jason C. George ,1 Waleed Zafar,2 Ion Dan Bucaloiu,1 and Alex R. Chang 1,2 Abstract Background and objectives Rapid correction of severe hyponatremia can result in serious neurologic complications, including osmotic demyelination. Few data exist on incidence and risk factors of rapid 1Department of correction or osmotic demyelination. Nephrology, Geisinger Medical Center, Design, setting, participants, & measurements In a retrospective cohort of 1490 patients admitted with serum Danville, , Pennsylvania; and sodium 120 mEq/L to seven hospitals in the Geisinger Health System from 2001 to 2017, we examined the 2 incidence and risk factors of rapid correction and osmotic demyelination. Rapid correction was defined as serum Kidney Health . Research Institute, sodium increase of 8 mEq/L at 24 hours. Osmotic demyelination was determined by manual chart review of Geisinger, Danville, all available brain magnetic resonance imaging reports. Pennsylvania Results Mean age was 66 years old (SD=15), 55% were women, and 67% had prior hyponatremia (last outpatient Correspondence: sodium ,135 mEq/L). Median change in serum sodium at 24 hours was 6.8 mEq/L (interquartile range, 3.4–10.2), Dr. Alexander R. Chang, and 606 patients (41%) had rapid correction at 24 hours. Younger age, being a woman, schizophrenia, lower Geisinger Medical , Center, 100 North Charlson comorbidity index, lower presentation serum sodium, and urine sodium 30 mEq/L were associated Academy Avenue, with greater risk of rapid correction.

341 Nutrient Deficiency Or Disease Definition/Cut-Off Value
10/2019 341 Nutrient Deficiency or Disease Definition/Cut-off Value Any currently treated or untreated nutrient deficiency or disease. These include, but are not limited to, Protein Energy Malnutrition, Scurvy, Rickets, Beriberi, Hypocalcemia, Osteomalacia, Vitamin K Deficiency, Pellagra, Xerophthalmia, and Iron Deficiency. Presence of condition diagnosed, documented, or reported by a physician or someone working under a physician’s orders, or as self-reported by applicant/participant/caregiver. See Clarification for more information about self-reporting a diagnosis. Participant Category and Priority Level Category Priority Pregnant Women 1 Breastfeeding Women 1 Non-Breastfeeding Women 6 Infants 1 Children 3 Justification Nutrient deficiencies or diseases can be the result of poor nutritional intake, chronic health conditions, acute health conditions, medications, altered nutrient metabolism, or a combination of these factors, and can impact the levels of both macronutrients and micronutrients in the body. They can lead to alterations in energy metabolism, immune function, cognitive function, bone formation, and/or muscle function, as well as growth and development if the deficiency is present during fetal development and early childhood. The Centers for Disease Control and Prevention (CDC) estimates that less than 10% of the United States population has nutrient deficiencies; however, nutrient deficiencies vary by age, gender, and/or race and ethnicity (1). For certain segments of the population, nutrient deficiencies may be as high as one third of the population (1). Intake patterns of individuals can lead to nutrient inadequacy or nutrient deficiencies among the general population. Intakes of nutrients that are routinely below the Dietary Reference Intakes (DRI) can lead to a decrease in how much of the nutrient is stored in the body and how much is available for biological functions. -

Magnesium Deficiency: a Possible Cause of Thiamine Refractoriness in Wernicke-Korsakoff Encephalopathy
J Neurol Neurosurg Psychiatry: first published as 10.1136/jnnp.37.8.959 on 1 August 1974. Downloaded from Journal of Neurology, Neurosurgery, and Psychiatry, 1974, 37, 959-962 Magnesium deficiency: a possible cause of thiamine refractoriness in Wernicke-Korsakoff encephalopathy D. C. TRAVIESA From the Department ofNeurology, University ofMiami School of Medicine, Miami, Florida, U.S.A. SYNOPSIS The determination of blood transketolase before and serially after thiamine administra- tion, and the response of clinical symptomatology after thiamine are reported in two normo- magnesaemic patients and one hypomagnesaemic patient with acute Wernicke-Korsakoff encephalopathy. The response of the depressed blood transketolase and the clinical symptoms was retarded in the hypomagnesaemic patient. Correction of hypomagnesaemia was accompanied by the recovery of blood transketolase activity and total clearing of the ophthalmoplegia in this patient, guest.

Previous studies have shown that the clinical vestibular nuclei (Prickett, 1934; Dreyfus and entity of Wernicke-Korsakoff encephalopathy is Victor, 1961; Dreyfus, 1965). related to an exclusive deficiency of thiamine (Phillips et al., 1952). Furthermore, improvement Blood transketolase activity is markedly re- in clinical symptoms, once the syndrome has de- duced in patients with Wernicke-Korsakoff veloped, occurs only with the repletion of thi- encephalopathy and serial assays in these patients amine. It is this obvious and seemingly pure usually reveal a rapid and essentially complete causal relationship of thiamine deficiency and recovery of the reduced blood transketolase Wernicke-Korsakoff encephalopathy that neces- activity after the parental administration of sitates the total understanding of thiamine thiamine (Brin, 1962; Dreyfus, 1962). -
Magnesium: the Forgotten Electrolyte—A Review on Hypomagnesemia
medical sciences Review Magnesium: The Forgotten Electrolyte—A Review on Hypomagnesemia Faheemuddin Ahmed 1,* and Abdul Mohammed 2 1 OSF Saint Anthony Medical Center, 5666 E State St, Rockford, IL 61108, USA 2 Advocate Illinois Masonic Medical Center, 833 W Wellington Ave, Chicago, IL 60657, USA; [email protected] * Correspondence: [email protected] Received: 20 February 2019; Accepted: 2 April 2019; Published: 4 April 2019 Abstract: Magnesium is the fourth most abundant cation in the body and the second most abundant intracellular cation. It plays an important role in different organ systems at the cellular and enzymatic levels. Despite its importance, it still has not received the needed attention either in the medical literature or in clinical practice in comparison to other electrolytes like sodium, potassium, and calcium. Hypomagnesemia can lead to many clinical manifestations with some being life-threatening. The reported incidence is less likely than expected in the general population. We present a comprehensive review of different aspects of magnesium physiology and hypomagnesemia which can help clinicians in understanding, identifying, and treating this disorder. Keywords: magnesium; proton pump inhibitors; diuretics; hypomagnesemia 1. Introduction Magnesium is one of the most abundant cation in the body as well as an abundant intracellular cation. It plays an important role in molecular, biochemical, physiological, and pharmacological functions in the body. The importance of magnesium is well known, but still it is the forgotten electrolyte. The reason for it not getting the needed attention is because of rare symptomatology until levels are really low and also because of a lack of proper understanding of magnesium physiology. -
Essential Trace Elements in Human Health: a Physician's View

Tomsk Publishing House of Tomsk State University 2018 2 Essential trace elements in human health UDK 612:577.1 LBC 52.57 S66 Skalnaya Margarita G., Skalny Anatoly V. S66 Essential trace elements in human health: a physician's view. – Tomsk : Publishing House of Tomsk State University, 2018. – 224 p. ISBN 978-5-94621-683-8 Disturbances in trace element homeostasis may result in the development of pathologic states and diseases. The most characteristic patterns of a modern human being are deficiency of essential and excess of toxic trace elements. Such a deficiency frequently occurs due to insufficient trace element content in diets or increased requirements of an organism. All these changes of trace element homeostasis form an individual trace element portrait of a person. Consequently, impaired balance of every trace element should be analyzed in the view of other patterns of trace element portrait. Only personalized approach to diagnosis can meet these requirements and result in successful treatment. Effective management and timely diagnosis of trace element deficiency and toxicity may occur only in the case of adequate assessment of trace element status of every individual based on recent data on trace element metabolism. Therefore, the most recent basic data on participation of essential trace elements in physiological processes, metabolism, routes and volumes of entering to the body, relation to various diseases, medical applications with a special focus on iron (Fe), copper (Cu), manganese (Mn), zinc (Zn), selenium (Se), iodine (I), cobalt (Co), chromium, and molybdenum (Mo) are reviewed. -

Poster Presentations Pelvic Inflammatory Disease: Challenges in Diagnosis (Clinical Inquiry) Catherine Peony Khoo, MD University of California, Los Angeles Pelvic inflammatory disease (PID) is a common infection with an estimated lifetime prevalence of 4.4% in reproductive-aged women in the United States. However, given its nonspecific signs and symptoms along with a lack of readily available specific diagnostic testing, PID remains a clinical diagnosis that may pose diagnostic challenges resulting in serious morbidity and mortality. The case presented is that of a perimenopausal woman presenting with fever and lower abdominal pain who was misdiagnosed on multiple occasions in both ambulatory and hospital settings until she was finally found to have sepsis secondary to PID complicated by tuboovarian abscess. Her case highlights multiple important points in diagnosis of PID, pathogenic organisms, and risk factors implicated in PID in postmenopausal women, treatment of PID, and cognitive error contributing to preventable misdiagnosis.
