Altarelli, M, Ben-Hamouda, N, Schneider, A, Berger, MM
Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition. 2019;(4):504-513
Abstract
BACKGROUND The metabolism of the essential trace element copper remains incompletely understood and, until recently, nearly ignored in acute medicine. Menkes disease was for long the only known copper deficiency condition, but several case reports and investigations conducted over the last 2 decades have shown that deficiency is more frequent than previously suspected, with devastating individual consequences and potential public health consequences. The copper needs in healthy individuals are 0.9 mg/d, which translates to 0.3 mg/d intravenously in parenteral nutrition; the present review aims at gathering actual knowledge. METHOD AND RESULTS A review of literature was conducted in PubMed and Cochrane systematic reviews to identify the most recent information about copper deficiency and generate a narrative review. Copper deficiency has hereditary and acquired origins, the latter being the most frequent. Clinical manifestations are nonspecific but affect all organs and systems, particularly the hematologic (anemia) and the neurologic (myeloneuropathy) systems. Deficiency also affects the cardiovascular, cutaneous, and immune systems. Severe copper deficiency due to reduced absorption after bariatric bypass surgery has become frequent. CONCLUSION Deficiency is more frequent than previously recognized, probably because of changing nutrition patterns but also because of some treatments that have become very common such as bypass bariatric surgery and, in acute medicine, prolonged continuous renal replacement therapy. The patients may present with severe hematologic and neurologic complications that go untreated because copper deficiency was not considered in the differential diagnosis: These complications often need active intravenous repletion with doses 4-8 times the usual nutrition recommendations.

Nutritional Modulation of Immune and Central Nervous System Homeostasis: The Role of Diet in Development of Neuroinflammation and Neurological Disease.
Estrada, JA, Contreras, I
Nutrients. 2019;(5)
Abstract
The gut-microbiome-brain axis is now recognized as an essential part in the regulation of systemic metabolism and homeostasis. Accumulating evidence has demonstrated that dietary patterns can influence the development of metabolic alterations and inflammation through the effects of nutrients on a multitude of variables, including microbiome composition, release of microbial products, gastrointestinal signaling molecules, and neurotransmitters. These signaling molecules are, in turn, implicated in the regulation of the immune system, either promoting or inhibiting the production of pro-inflammatory cytokines and the expansion of specific leukocyte subpopulations, such as Th17 and Treg cells, which are relevant in the development of neuroinflammatory and neurodegenerative conditions. Metabolic diseases, like obesity and type 2 diabetes mellitus, are related to inadequate dietary patterns and promote variations in the aforementioned signaling pathways in patients with these conditions, which have been linked to alterations in neurological functions and mental health. Thus, maintenance of adequate dietary patterns should be an essential component of any strategy aiming to prevent neurological pathologies derived from systemic metabolic alterations. The present review summarizes current knowledge on the role of nutrition in the modulation of the immune system and its impact in the development of neuroinflammation and neurological disease.

Kaplan, E, Daka, A, Weissbach, A, Kraus, D, Kadmon, G, Milkh, R, Nahum, E
Paediatric drugs. 2019;(5):371-378
Abstract
AIM: Triclofos sodium (TFS) has been used for many years in children as a sedative for painless medical procedures. It is physiologically and pharmacologically similar to chloral hydrate, which has been censured for use in children with neurocognitive disorders. The aim of this study was to investigate the safety and efficacy of TFS sedation in a pediatric population with a high rate of neurocognitive disability. METHODS The database of the neurodiagnostic institute of a tertiary academic pediatric medical center was retrospectively reviewed for all children who underwent sedation with TFS in 2014. Data were collected on demographics, comorbidities, neurologic symptoms, sedation-related variables, and outcome. RESULTS The study population consisted of 869 children (58.2% male) of median age 25 months (range 5-200 months); 364 (41.2%) had neurocognitive diagnoses, mainly seizures/epilepsy, hypotonia, or developmental delay. TFS was used for routine electroencephalography in 486 (53.8%) patients and audiometry in 401 (46.2%). Mean (± SD) dose of TFS was 50.2 ± 4.9 mg/kg. Median time to sedation was 45 min (range 5-245), and median duration of sedation was 35 min (range 5-190). Adequate sedation depth was achieved in 769 cases (88.5%). Rates of sedation-related adverse events were low: apnea, 0; desaturation ≤ 90%, 0.2% (two patients); and emesis, 0.35% (three patients). None of the children had hemodynamic instability or signs of poor perfusion. There was no association between desaturations and the presence of hypotonia or developmental delay. CONCLUSION TFS, when administered in a controlled and monitored environment, may be safe for use in children, including those with underlying neurocognitive disorders.

Comorbidities in inflammatory bowel disease: a call for action.
Argollo, M, Gilardi, D, Peyrin-Biroulet, C, Chabot, JF, Peyrin-Biroulet, L, Danese, S
The lancet. Gastroenterology & hepatology. 2019;(8):643-654
Abstract
Inflammatory bowel disease (IBD) is a chronic systemic inflammatory condition. Previously, the focus has been on extraintestinal manifestations of IBD, including arthritis, psoriasis, and uveitis. Although comorbidities have long been the subject of intensive research in other chronic inflammatory diseases such as rheumatoid arthritis, the concept of comorbidities is only beginning to emerge in IBD. Several comorbid conditions have been proposed to be related to IBD, including cardiovascular disease, neuropsychological disorders, and metabolic syndrome. Recognition of these conditions and their treatment could lead to better management of IBD. This Review aims to explore current knowledge regarding classic and emerging comorbidities related to IBD.

Tracheostomies and PEGs: When Are They Really Indicated?
Hoffman, MR
The Surgical clinics of North America. 2019;(5):955-965
Abstract
Surgeons are often asked to perform tracheostomies and percutaneous endoscopic gastrostomies for a wide variety of patients. As consultants, surgeons are tasked with honoring the relationship between the referring provider and the patient while also assessing whether the consult is appropriate given the patient's prognosis and goals of care. This article discusses the most common conditions for which these procedures are requested and reviews the evidence supporting either the placement or avoidance of these tubes in each condition. It provides a framework for surgeons to use when discussing these procedures in the context of goals of care.

Food and Food Products on the Italian Market for Ketogenic Dietary Treatment of Neurological Diseases.
Leone, A, De Amicis, R, Lessa, C, Tagliabue, A, Trentani, C, Ferraris, C, Battezzati, A, Veggiotti, P, Foppiani, A, Ravella, S, et al
Nutrients. 2019;(5)
Abstract
The ketogenic diet (KD) is the first line intervention for glucose transporter 1 deficiency syndrome and pyruvate dehydrogenase deficiency, and is recommended for refractory epilepsy. It is a normo-caloric, high-fat, adequate-protein, and low-carbohydrate diet aimed at switching the brain metabolism from glucose dependence to the utilization of ketone bodies. Several variants of KD are currently available. Depending on the variant, KDs require the almost total exclusion, or a limited consumption of carbohydrates. Thus, there is total avoidance, or a limited consumption of cereal-based foods, and a reduction in fruit and vegetable intake. KDs, especially the more restrictive variants, are characterized by low variability, palatability, and tolerability, as well as by side-effects, like gastrointestinal disorders, nephrolithiasis, growth retardation, hyperlipidemia, and mineral and vitamin deficiency. In recent years, in an effort to improve the quality of life of patients on KDs, food companies have started to develop, and commercialize, several food products specific for such patients. This review summarizes the foods themselves, including sweeteners, and food products currently available for the ketogenic dietary treatment of neurological diseases. It describes the nutritional characteristics and gives indications for the use of the different products, taking into account their metabolic and health effects.

Impact of gut microbiota on neurological diseases: Diet composition and novel treatments.
Larroya-García, A, Navas-Carrillo, D, Orenes-Piñero, E
Critical reviews in food science and nutrition. 2019;(19):3102-3116
Abstract
Gut microbiota has significant effects on the structure and function of the enteric and central nervous system including human behaviour and brain regulation. Herein, we analyze the role of this intestinal ecosystem, the effects of dietary changes and the administration of nutritional supplements, such as probiotics, prebiotics, or fecal transplantation in neuropsychiatric disorders. Numerous factors have been highlighted to influence gut microbiota composition, including genetics, health status, mode of birth delivery and environment. However, diet composition and nutritional status has been repeatedly shown to be one of the most critical modifiable factors of this ecosystem. A comprehensively analysis of the microbiome-intestine-brain axis has been performed, including the impact of intestinal bacteria in alterations in the nervous, immune and endocrine systems and their metabolites. Finally, we discuss the latest literature examining the effects of diet composition, nutritional status and microbiota alterations in several neuropsychiatric disorders, such as autism, anxiety, depression, Alzheimer's disease and anorexia nervosa.

Obesity and neurological disorders: Dietary perspective of a global menace.
Bhat, ZF, Morton, JD, Mason, S, Bekhit, AEA, Bhat, HF
Critical reviews in food science and nutrition. 2019;(8):1294-1310
Abstract
Obesity is considered a major public health concern throughout the world among children, adolescents, as well as adults and several therapeutic, preventive and dietary interventions are available. In addition to life style changes and medical interventions, significant milestones have been achieved in the past decades in the development of several functional foods and dietary regimens to reduce this menace. Being a multifactorial phenomenon and related to increased fat mass that adversely affects health, obesity has been associated with the development of several other co-morbidities. A great body of research and strong scientific evidence identifies obesity as an important risk factor for onset and progression of several neurological disorders. Obesity induced dyslipidaemia, metabolic dysfunction, and inflammation are attributable to the development of a variety of effects on central nervous system (CNS). Evidence suggests that neurological diseases such as Parkinson's disease and Alzheimer's disease could be initiated by various metabolic changes, related to CNS damage, caused by obesity. These metabolic changes could alter the synaptic plasticity of the neurons and lead to neural death, affecting the normal physiology of CNS. Dietary intervention in combination with exercise can affect the molecular events involved in energy metabolism and synaptic plasticity and are considered effective non-invasive strategy to counteract cognitive and neurological disorders. The present review gives an overview of the obesity and related neurological disorders and the possible dietary interventions.

[Alcohol and Neurology].
Dematteis, M, Pennel, L
Presse medicale (Paris, France : 1983). 2018;(7-8 Pt 1):643-654
Abstract
The nervous system is a particular target tissue for alcohol due to desired effects and numerous acute and chronic consequences. Acute consequences are due to episodes of overconsumption, withdrawal syndromes, or decompensation of nutritional deficiencies. Chronic consequences are dominated by sleep disorders, chronic pain and cognitive-behavioral disorders, stroke, and impairments of balance, peripheral nerves and muscles, resulting from direct toxicity and/or nutritional deficiencies. There is a bidirectional relationship requiring seeking: alcohol use as a causal or aggravating factor in any neurological disorder ; and neurological disorders in cases of alcohol use, especially when problematic. Management of alcohol-related neurological consequences can help reduce or stop alcohol consumption, prevent relapse, and improve patients' quality of life.
