COVID-19: Relationship and Impact on Breastfeeding-A Systematic Review.
2021
COVID-19 is an infectious disease caused by the SARS-CoV-2 virus that was declared a Public Health Emergency of International Concern by the World Health Organization (WHO). One major problem faced is whether breastfeeding by mothers infected with the virus is safe. The objective of this work is to study the impact that the SARS-CoV-2 virus can have on breastfeeding, and whether the virus or antibodies can be transmitted from mother to child through milk. We carried out a systematic review of studies focusing on the impact of SARS-CoV-2 on breastfeeding by mothers infected with the virus. The bibliographic search was done through Medline (Pubmed), MedlinePlus and Google Scholar. From 292 re…
Can Ketogenic Diet Improve Alzheimer's Disease? Association With Anxiety, Depression, and Glutamate System
2021
Background: Alzheimer's disease is the most common neurodegenerative disorder in our society, mainly characterized by loss of cognitive function. However, other symptoms such as anxiety and depression have been described in patients. The process is mediated by alterations in the synaptic and extrasynaptic activity of the neurotransmitter glutamate, which are linked to a hypometabolism of glucose as the main source of brain energy. In that respect, Ketogenic diet (KD) has been proposed as a non-pharmacological treatment serving as an alternative energy source to the neurons increasing the fat percentage and reducing the carbohydrates percentage, showing promising results to improve the cogni…
Isoflavones and cardiovascular disease
2010
The specific profile of estrogens on cardiovascular risk, with limiting action on atherogenesis but a less clear protection on cardiovascular episodes, might be improved by other agonists of the estrogen receptor, such as isoflavones. By using a systematic search based on the electronic Medline database plus a hand-search of reference lists of selected review papers, we reviewed the rapidly growing body of experimental and clinical data that, on average, follow a pattern of benefit rather similar to estrogens. Experimental models have used endothelial and vascular smooth muscle cells, isolated arteries, and live animals, including monkeys. The clinical evidence arises from studies on the li…
Ingesta nutricional en pacientes afectados de esclerosis lateral amiotrófica una consulta ambulatoria de nutrición artificial en Portugal
2021
Introducción: La Esclerosis Lateral Amiotrófica (ELA) es una patología neurodegenerativa crónica y progresiva, que produce la muerte de las motoneuronas. Deriva en pérdida de peso, de masa muscular e incremento de deficiencias nutricionales. Existe relación entre la ingesta nutricional y la patogénesis de la ELA. El objetivo de este análisis fue describir las características sociodemográficas, antropométricas y clínicas junto con la ingesta nutricional en una muestra de pacientes portugueses afectados de ELA. Material y Métodos: Se realizó una anamnesis clínica breve. El peso corporal fue evaluado siguiendo el protocolo de la International Society for the Advancement of Kinanthropometry (IS…
Rôle des lipides dans la régulation du comportement alimentaire
2008
Obesity constitutes a major public health problem for the 21 st Century, with its epidemic spread worldwide, particularly in children. The overconsumption of fatty foods greatly contributes to this phenomenon. Rodents and humans display a spontaneous preference for lipid-rich foods. But why are lipids so attractive? What are the molecular mechanisms involved? The purpose of this mini review is to explore few basic questions raised by recent data providing evidences on the relationships between dietary lipids and feeding behavior.

Protein supplementation in strength and conditioning adepts: knowledge, dietary behavior and practice in Palermo, Italy
2011
Abstract Background It is known that supplement use is a widespread and accepted practice by athletes and people who attend commercial gyms. Little is known about protein supplement amongst people undertaking strength training in commercial gyms in Italy when compared to the US. Objective The purpose of this study was to examine the use of protein supplementation, alone or in association with other supplements, and dietary behavior amongst regular fitness center attendees in Palermo, Italy. Design Resistance training information have been collected from 800 regular fitness center attendees for the initial analysis. A specific questionnaire was generated for the experimentation. Data were co…
Low-protein vegetarian diet does not have a short-term effect on blood acid–base status but raises oxygen consumption during submaximal cycling
2012
Abstract Background Acid–base balance refers to the equilibrium between acids and bases in the human body. Nutrition may affect acid–base balance and further physical performance. With the help of PRAL (potential renal acid load), a low-protein vegetarian diet (LPVD) was designed to enhance the production of bases in body. The aim of this study was to investigate if LPVD has an effect on blood acid–base status and performance during submaximal and maximal aerobic cycling. Methods Nine healthy, recreationally active men (age 23.5 ± 3.4 yr) participated in the study and were randomly divided into two groups in a cross-over study design. Group 1 followed LPVD for 4 days and group 2 ate normall…
In vivo antihypertensive mechanism of lactoferrin-derived peptides: Reversion of angiotensin I- and angiotensin II-induced hypertension in Wistar rats
2015
Novel peptides with antihypertensive effects in SHR rats have previously been identified in lactoferrin (LF) hydrolysates. To investigate their in vivo antihypertensive mechanism, we have assessed the blood pressure lowering effects of two of these LF-derived peptides (RPYL and DPYKLRP) in Wistar rats subjected to either angiotensin I- or angiotensin II-induced hypertension. Blood pressure was measured by the tail-cuff method, hypertension was induced by subcutaneous infusion of angiotensins, and then captopril, valsartan or LF-derived peptides orally administered. Angiotensin I- and angiotensin II-induced hypertension were reversed by captopril and valsartan, respectively. RPYL and DPYKLRP…
Chronic consumption of an inositol-enriched beverage ameliorates endothelial dysfunction and oxidative stress in type 2 diabetes
2015
The anti-diabetic properties of an inositol-enriched beverage (IEB) on the endothelial function and redox status in diabetic subjects were assessed. This was a 12-week, double-blind randomized controlled trial employing thirty-eight diabetic subjects that were divided into two intervention groups: one receiving an IEB and the other a sucrose-enriched beverage. Subjects consuming IEB exhibited a significant decrease in triacylglycerol (8.82%) and HbA1c (4.53%) levels. Continuous glucose monitoring revealed a significant net reduction of 2.51 and 7.11% during postprandial and overnight fasting periods after consumption of IEB, respectively. Moreover, IEB improved endothelial function by reduc…
