Cashew nut consumption reduces waist circumference and oxidative stress in adolescents with obesity: A randomized clinical trial.

Previous evidence suggests that certain types of nuts, when included in a healthy diet pattern, may provide health benefits. Therefore, we hypothesize that the consumption of cashew nuts associated with a healthy diet may enhance antioxidant defenses and improve anthropometric and body composition parameters in individuals with obesity. We conducted a 12-week randomized clinical trial, divided into 4 sessions, involving adolescents randomly assigned to receive either 30 g of roasted cashew nuts together with nutrition education (cashew nut group-CNG) or only nutrition education (control group-CG).

The Interaction Between Indigenous Identity and Rural Residency in Dementia Prevalence Among Ecuadorian Older Adults.

Background And Objectives: While recognizing the acknowledged difference in dementia prevalence between Indigenous and non-Indigenous populations, most previous studies were conducted in the Global North. This study aims to examine the relationship between Indigenous ethnic identity and dementia status with a special focus on urban-rural differences among older adults in Ecuador.

Research Design And Methods: Data came from Ecuador's Survey of Health, Welfare, and Aging, derived from a probability sample of households in Ecuador.

SARS-CoV-2 shedding, infectivity, and evolution in an immunocompromised adult patient.

This study aimed to provide further insight into the evolutionary dynamics of SARS-CoV-2 by analyzing the case of a 40-year-old man who had previously undergone autologous hematopoietic stem cell transplantation due to a diffuse large B-cell lymphoma. He developed a persistent SARS-CoV-2 infection lasting at least 218 days and did not manifest a humoral immune response to the virus during this follow-up period. Whole-genome sequencing and viral cultures confirmed a persistent infection with a replication-positive virus that had undergone genetic variation for at least 196 days after symptom onset.

Characterization of Torquetenovirus in amniotic fluid at the time of fetal surgery: correlation with early premature delivery and respiratory distress.

Torquetenovirus (TTV) is a commensal virus present in many healthy individuals. Although considered to be non-pathogenic, its presence and titer have been shown to be indicative of altered immune status in individuals with chronic infections or following allogeneic transplantations. We evaluated if TTV was present in amniotic fluid (AF) at the time of surgery to correct a fetal neurological defect, and whether its detection was predictive of adverse post-surgical parameters.

SARS-CoV-2 Detection and Culture in Different Biological Specimens from Immunocompetent and Immunosuppressed COVID-19 Patients Infected with Two Different Viral Strains.

Introduction-The dynamics of SARS-CoV-2 shedding and replication in humans remain incompletely understood. Methods-We analyzed SARS-CoV-2 shedding from multiple sites in individuals with an acute COVID-19 infection by weekly sampling for five weeks in 98 immunocompetent and 25 immunosuppressed individuals. Samples and culture supernatants were tested via RT-PCR for SARS-CoV-2 to determine viral clearance rates and in vitro replication.

Towards a Secure and Scalable Maritime Monitoring System Using Blockchain and Low-Cost IoT Technology.

Maritime Domain Awareness (MDA) is a strategic field of study that seeks to provide a coastal country with an effective monitoring of its maritime resources and its Exclusive Economic Zone (EEZ). In this scope, a Maritime Monitoring System (MMS) aims to leverage active surveillance of military and non-military activities at sea using sensing devices such as radars, optronics, automatic Identification Systems (AISs), and IoT, among others. However, deploying a nation-scale MMS imposes great challenges regarding the scalability and cybersecurity of this heterogeneous system.

Torquetenovirus in saliva: A potential biomarker for SARS-CoV-2 infection?

Torquetenovirus (TTV) is present in biological fluids from healthy individuals and measurement of its titer is used to assess immune status in individuals with chronic infections and after transplants. We assessed if the titer of TTV in saliva varied with the presence of SARS-CoV-2 in the nasopharynx and could be a marker of COVID-19 status. Saliva from 91 individuals positive for SARS-CoV-2 in nasal-oropharyngeal samples, and from 126 individuals who were SARS-CoV-2-negative, all with mild respiratory symptoms, were analyzed.

Ethnic Disparities in Nutritional Status among Older Adults: Evidence from the Survey of Health, Welfare and Aging (SABE) Ecuador.

Torquetenovirus Titer in Vaginal Secretions from Pregnant and Postpartum Women: Association with Absence of Lactobacillus crispatus and Levels of Lactic Acid and Matrix Metalloproteinase-8.

Vaginal samples from women with term deliveries were tested for torquetenovirus (TTV) by gene amplification, matrix metalloproteinase (MMP)-8 and D- and L-lactic acid by ELISA, and microbiome composition by analysis of the bacterial 16S ribosomal RNA gene. TTV was detected in 43.2%, 31.

Breastfeeding practices and complementary feeding in Ecuador: implications for localized policy applications and promotion of breastfeeding: a pooled analysis.

Background: Best practices in breastfeeding are often not followed despite appropriate levels of knowledge and positive attitudes regarding the benefits of human milk. For many reasons, some women do not initiate breastfeeding, suspend breastfeeding early, or initiate complementary feeding earlier than recommended. Usual measurement methods use large sample surveys at a national scale, which are not well suited for monitoring sub-national differences.

Prevalence of overweight and metabolic syndrome, and associated sociodemographic factors among adult Ecuadorian populations: the ENSANUT-ECU study.

Background: Obesity and metabolic syndrome (MetS) are key risk factors for type 2 diabetes and cardiovascular disease. Little information exists on the prevalence of obesity and MetS in Latin America and specifically in Ecuador. We aimed to estimate the prevalence of overweight, obesity, and MetS among adults in Ecuador.

Malnutrition inequalities in Ecuador: differences by wealth, education level and ethnicity.

Objective: To describe and quantify the magnitude and distribution of stunting, wasting, anaemia, overweight and obesity by wealth, level of education and ethnicity in Ecuador.

Design: We used nationally representative data from the 2012 Ecuadorian National Health and Nutrition Survey. We used the Multidimensional Poverty Index (MPI) as a proxy of wealth.

Use, knowledge, and effectiveness of nutritional traffic light label in an urban population from Ecuador: a pilot study.

Background: The nutritional traffic light label (NTLL) has become one of the most used Front of Package labels (FOP's) around the world, for its simple and easy to understand graphical system. In Ecuador, this labelling system has recently been implemented; then, this research aims to evaluate the use and knowledge of NTLL and its effectiveness as a public health promotion strategy.

Method: In a cross-sectional study at two different urban supermarkets in Quito-Ecuador, a survey was conducted in 73 participants to inquire about knowledge, perspectives and purchasing habits regarding the NTLL.

Overweight, obesity, and food consumption in Galapagos, Ecuador: a window on the world.

Background: In order to understand why rates of overweight and obesity are so high in the Ecuadorian province of Galapagos, this study analyzes changes in household food expenditures and perceptions and practices related to food consumption patterns. Galapagos is understood as an unusual but not unique case because conditions there graphically illustrate trends observed in communities and countries worldwide. A mixed methods approach was employed: a quantitative component was based on expenditures for foods classified according to the NOVA system, and a qualitative component utilized focus group discussions, key informant interviews, and structured observations.

The double burden of chronic malnutrition and overweight and obesity in Ecuadorian mothers and children, 1986-2012.

Background:: The simultaneous presence of undernutrition and over-nutrition represents a paradox in global public health and is of increasing concern in Ecuador, where chronic malnutrition and overweight and obesity occur in the context of demographic and epidemiologic transitions. Two overlapping trends are present in Ecuador; while levels of stunting have decreased slowly in the past three decades, increasing proportions of children <5 years and women of reproductive age suffer from overweight and obesity.

Aim:: To analyze stunting and overweight and obesity in children <5 and their mothers aged from 15 to 49 years in the context of demographic and household characteristics between 1986 and 2012.

Decreased serum level of miR-146a as sign of chronic inflammation in type 2 diabetic patients.

Background: There is increasing evidence that chronic inflammation is an important determinant in insulin resistance and in the pathogenesis of type 2 diabetes (T2D). MicroRNAs constitute a newly discovered system of cell regulation and in particular two microRNAs (miR-146a and miR-155) have been described as regulators and biomarkers of inflammation.

Aim: To determine a putative association between the levels of miR-146a and miR-155 in serum of T2D patients, clinical parameters and serological indicators of inflammation.

The double burden of undernutrition and excess body weight in Ecuador.

Background: Ecuador's current nutrition policies have not taken adequate notice of the double burden of malnutrition and continue to focus on stunting and to a lesser extent on overweight, without addressing the simultaneous presence of undernutrition, micronutrient deficiencies, and overweight or obesity (OW/OB).

Objective: The aim of this article was to describe the prevalence and distribution of undernutrition (stunting, anemia, and zinc deficiency), overweight, and obesity in Ecuador to explore the evolving double burden of malnutrition at the national, household, and individual levels and to discuss whether current public health policies are addressing the double burden.

Design: Data from the 2012 Ecuadorian National Health and Nutrition Survey (ENSANUT-ECU) was used to estimate the dual burden of malnutrition at the national, household, and individual levels in children <5 y old, school-aged children, and women of reproductive age.

(-)-α-Bisabolol inhibits preferentially electromechanical coupling on rat isolated arteries.

Previous findings enable us to hypothesize that (-)-α-bisabolol acts as inhibitor of voltage-dependent Ca(2+) channels in smooth muscle. The current study was aimed at consolidating such hypothesis through the recording of isometric tension, measurement of intracellular Ca(2+) as well as discovery of channel target using in silico analysis. In rat aortic rings, (-)-α-bisabolol (1-1000 µM) relaxed KCl- and phenylephrine-elicited contractions, but the IC50 differed significantly (22.
