Amino acids profile after oral nutritional supplementation in hemodialysis patients with protein energy wasting
Some studies have shown abnormalities of nutritional status in patients with chronic kidney disease (CKD) [1,2]. Protein energy wasting (PEW) is highly prevalent in haemodialysis (HD) patients [3,4]. The underlying mechanisms of PEW are complex, but metabolic derangements related both to exaggerated protein degradation and decreased protein synthesis are of utmost importance [5,6,7,8]. Homeostasis between protein synthesis and degradation depends on protein intake and utilization. Accelerated protein degradation, without a sufficient protein supply, may lead to skeletal muscle wasting (9). (Source: Nutrition)

Development, validity and reproducibility of a semi-quantitative food frequency questionnaire for the assessment of antioxidant vitamins intake in Lebanon.
The growing interest in the possible role of antioxidant vitamins in many pathologies (such as Alzheimer's disease (Mehta et al., 2017), cancer (Khurana et al., 2018), cardiovascular disease (Billingsley& Carbone, 2018) ….) make the development of methods to evaluate the intake of these vitamins necessary. Different tools exist to evaluate the dietary intakes of an individual or a population such as FFQs, 24HR and dietary journals [11]. FFQ is the most commonly used tool in epidemiological studies and large-scale surveys to assess long-term nutritional exposure and determine the usual food intakes of specific foods or nu...

Effect of resveratrol supplementation on lipid profile in subjects with dyslipidemia: A randomized double-blind placebo-controlled trial
It is well-known that elevated concentrations of circulating lipids are a strong risk factor for cardiovascular disease [1]; in this regard, the high levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C), or triglycerides as well as the low concentrations of high-density lipoprotein cholesterol (HDL-C) are consistently associated to future cardiovascular disease [2 –4], and their interactions exert a cumulative effect in the increasing cardiovascular mortality [5,6]. Therefore, given the high prevalence of dyslipidemia worldwide, the search of complementary therapies to treat lipid abnormalities in hig...

Infectious complications in home parenteral nutrition: a long-term study with peripherally inserted central catheters, tunneled catheters and ports.
Parenteral nutrition has become a common therapy for patients at home. National registries in North America, including 1251 patients enrolled from 29 sites for the last years, showed a 28% of all patients expected to require HPN indefinitely [1]. In Spain, the last analysis of our national registry has shown a total of 220 patients and 229 episodes of HPN registered from 37 centers that represents a rate of 4.7 patients/million habitants/year [2]. Currently, the leading cause for HPN is cancer in adults and congenital intestinal disorders in children [2,3]. (Source: Nutrition)

Dietary intake of magnesium and the risk of epilepsy in middle-aged and older Finnish men: a 22-year follow-up study in general population
Epilepsy is one the most important neurologic diseases [1], which needs to be prevented or treated. Nutrition may play a role in physiopathology of epilepsy. Nutrients such as polyunsaturated fatty acids have also been used in the treatment of epilepsy [2]. Minerals may either exacerbate or attenuate severity of epileptic seizures [3]. However, the role of magnesium in the management of epilepsy, especially in adults, has not been fairly considered by epidemiological or clinical trial studies. Human studies have considered the role of magnesium in the control of seizure, mainly in infants, and found that magnesium suppleme...

Ingestion of soy protein isolate attenuates eccentric contraction-induced force depression and muscle proteolysis via inhibition of calpain-1 activation in rat fast-twitch skeletal muscle
Eccentric contraction (ECC) is a contraction in which skeletal muscles are stretched while contracting, and it tends to result in a larger and longer-lasting force deficit compared to concentric and isometric contractions [1,2]. Following ECC, there is often muscle injury that is characterized by, e.g., proteolysis of muscle proteins, damage to sarcomeres and plasma membranes, inflammation and swelling, and delayed onset muscle soreness and stiffness [1,3,4,5,6]. Although it remains unclear to what extent these changes contribute to ECC-induced force deficit, recent studies suggest that large and long-lasting force deficit...

Coffee and tea consumption and the risk of subarachnoid hemorrhage: a meta-analysis
SAH is a subversive type of stroke that has a mortality rate of almost 50% [1, 2]. Approximately 10% of patients die during the prehospital period, and survivors often suffer long-term neurological or cognitive impairments due to the original hemorrhage and rehemorrhage despite the development of novel treatment strategies [3 –5]. Therefore, clarifying the risk factors of SAH remains important. Except for the most common risk factors of SAH, including hypertension, smoking, and heavy alcohol intake, the relation between diet and SAH has been a recent concern [6]. (Source: Nutrition)

“Update on Glucose in Critical Care”
The interest for the metabolic changes associated with critical illness, and in particular the issue of stress hyperglycemia (SH) increased widely over the last 20 years. SH generally refers to transient hyperglycemia during illness and is usually restricted to patients without previous evidence of diabetes [1,2]. According to the American Diabetes Association [3], there are two categories of SH depending on pre-existence of diabetes: 1) fasting glucose> 125mg/dL or a record higher than 200mg/dL at any point in its evolution without evidence of previous diabetes; 2) pre-existing diabetes with deterioration of pre-illness g...

The effects of cholecalciferol supplementation on the inflammatory markers and muscle damage indices of soccer players after a simulated soccer match: A double-blind, placebo-controlled, randomized trial
Inflammation, muscle damage, and muscle pain are the most common problems in athletes [1, 2]. Hence, while vigorous exercise results in beneficial effects on athletes ’ health, it can also leads to a loss of energy, inflammation, oxidative stress, and muscle damage, which can have adverse effects on some body organs and negative impacts on general health [3-5]. Soccer is considered the most popular and lucrative sports in the world; it requires muscle strength, aerobic capacity, and high speed [6, 7]. (Source: Nutrition)

Bioavailability of coenzyme Q10 supplements depends on carrier lipids and solubilization
Coenzyme Q10 (CoQ10) is an essential component of the human electron transport chain in mitochondria, and also an important lipid-soluble antioxidant that protects cell membranes and lipoproteins against oxidative damage [1-3]. CoQ10 (in its oxidized form, ubiquinone) can be reduced by many oxidoreductases to maintain a redox cycle [3]. In its reduced form, CoQ10H2 (ubiquinol) is able to transfer electrons to acceptors such as complex III in the mitochondrial electron transport chain (ETC) or, for example, to α-tocopherol in other cellular membranes [3].

Re: “Changes in lipid metabolism in pediatric patients with severe sepsis and septic shock”
We would like to congratulate the authors [1] for their careful and interesting article, and offer some considerations and questions regarding their work on pediatric sepsis. We became interested in the association between severe hypocholesterolemia and poor outcome in septic adults by serendipity, as cholesterol has long been part of the standard biochemistry profile of our surgical patients. After a few decades, doubts and uncertainty still remain and any study yielding valuable information on pediatric septic patients [1] is welcome and precious. (Source: Nutrition)
