Importance of Microbiome of Fecal Samples Obtained from Adolescents with Different Weight Conditions on Resistance Gene Transfer.

Antimicrobial resistance (AMR) is a relevant public health problem worldwide, and microbiome bacteria may contribute to the horizontal gene transfer associated with antimicrobial resistance. The microbiome of fecal samples from Mexican adolescents were analyzed and correlated with eating habits, and the presence of AMR genes on bacteria in the microbiome was evaluated. Fecal samples from adolescents were collected and processed to extract genomic DNA.

Neck circumference cut-offs for overweight and obesity in a group of Mexican adolescents.

Background/objectives: Neck circumference (NC) has been used for screening overweight/obesity for its high correlation with age, weight, body mass index (BMI), and waist circumference (WC). Cut-offs should be population specific. The aim of the study was to obtain cut-offs of NC for overweight/obesity in Mexican adolescents and to correlate them with anthropometric indicators.

Influenza A H1N1 Virus 2009 Synthetic Hemagglutinin and Neuraminidase Peptides for Antibody Detection.

Background: Influenza serologic diagnosis is mainly based on hemagglutination inhibition and microneutralization methods, both methods require handling living viruses under an enhanced biosafety level.

Aim: The current study was performed for developing an ELISA using synthetic peptides to detect influenza A H1N1 virus 2009 specific antibodies in serum and saliva.

Methods: Alignments were made with H1N1 hemagglutinin and neuraminidase (HA and NA, respectively) sequences; only conserved sites were used for antigenicity prediction.

Assessing the measurement invariance of a Latin-American Spanish translation of the Body Appreciation Scale-2 in Mexican, Argentinean, and Colombian adolescents.

In order to advance in the study of positive body image among different cultures, it is important to create culturally appropriate measures. We examined the psychometric properties of a Latin-American Spanish translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a), specifically assessing measurement invariance using a large sample of 3845 male and female adolescents from Argentina, Mexico, and Colombia. Participants completed the BAS-2, Eating Disorder Inventory-2, Male Body Attitude Scale and the Sociocultural Attitudes Toward Appearance Questionnaire-3.

[Flu symptoms and preventive measures practiced by the inhabitants of Mexico City during the AH1N1 influenza epidemic].

Objective: To know the frequency of flu symptoms and describe preventive measures practiced by the inhabitants of Mexico City during the AH1N1 epidemic.

Material And Methods: A cross-sectional design was used and a survey containing demographic and health information was conducted in August and September 2009 in a sample of 4003 randomly selected people living in Mexico City.

Results: Referred flu symptoms were: 29% running nose, 25% cough, 25% throat infection, 17% muscle and joint pain, 10% respiratory problems, and 7% fever.

Blastocystis hominis among food vendors in Xochimilco markets.

Blastocystis hominis is a pathogenic protozoon that lives in the human bowel and causes diarrhea: the mode of transmission is a passive one, through the ingestion of stool-contaminated water or foods that contain infective forms of the parasite. The purpose of this study is to report the prevalence of Blastocystis hominis among food vendors in the markets within the Xochimilco jurisdiction, Mexico City, Mexico. A cross-sectional study was conducted in which food vendors answered an epidemiological questionnaire and underwent a serial stool culture.
