Prevalence, Incidence, and Progression of Erosive Tooth Wear and Their Respective Risk Factors Among Schoolchildren in Mexico City.

To evaluate the cumulative incidence and progression of erosive tooth wear (ETW) and identify risk factors over 18 months in a cohort of 11- to 14-year-old schoolchildren in Mexico. The study was conducted in public schools located in northern Mexico City. Permanent teeth of 424 schoolchildren were examined using the basic erosive wear examination.

Nutrition Label Use Is Related to Chronic Conditions among Mexicans: Data from the Mexican National Health and Nutrition Survey 2016.

Background: Non-communicable diseases, such as obesity, diabetes, and hypertension, can be prevented and treated through a balanced nutrient-rich diet. Nutrition labels have been recognized as crucial to preventing obesity and non-communicable diseases through a healthier diet.

Objective: Our aim was to examine the association between nutrition label use and chronic conditions (overweight, obesity, previously diagnosed diabetes, and hypertension) among an adult Mexican population.

Neuropsychiatric symptoms as risk factors of dementia in a Mexican population: A 10/66 Dementia Research Group study.

Introduction: Cognitive and/or memory impairment are the main clinical markers currently used to identify subjects at risk of developing dementia. This study aimed to explore the relationship between the presence of neuropsychiatric symptoms and dementia incidence.

Methods: We analyzed the association between neuropsychiatric symptoms and incident dementia in a cohort of 1355 Mexican older adults from the general population over 3 years of follow-up, modeling cumulative incidence ratios using Poisson models.

Association of hypertension-related distress with lack of self-care among hypertensive patients.

Research on factors associated with poor adherence to self-care focuses primarily on psychiatric emotional disorders such as depression and anxiety, whereas non-psychiatric chronic-disease-related emotional distress has received little attention in hypertensive patients. The objective of this study was to evaluate the association of hypertension-related distress with the lack of self-care including low adherence to pharmacological treatment, lack of regular physical activity, low intake of fruits and vegetables and frequent intake of high-salt foods. A cross-sectional survey was conducted in 2014 in two family medical units affiliated with the Mexican Institute of Social Security.

Adaptation and validation of the Distress Scale for Mexican patients with type 2 diabetes and hypertension: a cross-sectional survey.

Objectives: The aim of this study was to adapt and validate the Distress Scale for Mexican patients with type 2 diabetes and hypertension (DSDH17M).

Setting: Two family medicine clinics affiliated with the Mexican Institute of Social Security.

Participants: 722 patients with type 2 diabetes and/or hypertension (235 patients with diabetes, 233 patients with hypertension and 254 patients with both diseases).

Needs of caregivers of cancer patients: validation of the Mexican version of the Support Person Unmet Needs Survey (SPUNS-SFM).

Purpose: The purpose of this study was to validate the Mexican version of the Support Person Unmet Needs Survey (SPUNS-SFM).

Methods: A cross-sectional survey that included 826 primary caregivers of cancer patients was conducted from June to December 2013 at the Oncology Hospital of the Mexican Institute of Social Security in Mexico City. The validation procedure comprised (1) content validity through a group of experts; (2) construct validity through an exploratory factor analysis based on the polychoric correlation matrix; (3) internal consistency using Cronbach's alpha; (4) convergent validity between SPUNS-SFM and quality of life, anxiety-and-depression scales by calculating Spearman's rank correlation coefficient;( 5) discriminative validity through the Wilcoxon rank-sum test; and (6) test-retest reliability using intraclass correlation coefficient.

Supportive care needs of Mexican adult cancer patients: validation of the Mexican version of the Short-Form Supportive Care Needs Questionnaire (SCNS-SFM).

Purpose: The purpose of this study is to validate the Mexican version of the Short-Form Supportive Care Needs survey (SCNS-SFM).

Methods: A cross-sectional survey was conducted from June to December 2013 at the Oncology Hospital of the Mexican Institute of Social Security in Mexico City. The study included 825 subsequent cancer patients >20 years of age with all forms of solid cancer.

[Adaptation and validation of scales to measure self-efficacy and empowerment for self-care in Mexican climacteric stage women].

Objective: To adapt and validate in Spanish of Mexico scales to measure self-efficacy (SES) and empowerment for self-care (ES) among climacteric women.

Materials And Methods: The study was conducted from February to July 2011 in two family medicine clinics in Mexico City. The adaptation phase was done through testing for language comprehension.

[Interpersonal relationships: perception of the communication, treatment and adverse experiences encountered by users of medical units that belong to the Coordinating Commission of the National Institutes of Health and High Specialty Hospitals (CCINSHAE)].

Introduction: User's perception with regard to the attention they received in healthcare units is increasingly being taken into account by the health service providers in order to improve the quality of their service.

Aim: Describe how the users perceive the health services provided by the CCINSHAE with regard to the communication with the physicians, the attention of the staff and the adverse personal and institutional experiences and to explore their relation with user's demographic characteristics, health condition, physical limitations to carry out daily activities and service area.

Methods: A questionnaire was designed to collect information about the user and his/her opinion with regard to the healthcare units, the communication with the physicians, the attention of the staff and the adverse personal and institutional experiences.

Ontogenetic modulation of branch size, shape, and biomechanics produces diversity across habitats in the Bursera simaruba clade of tropical trees.

Organismal size and shape inseparably interact with tissue biomechanical properties. It is therefore essential to understand how size, shape, and biomechanics interact in ontogeny to produce morphological diversity. We estimated within species branch length-diameter allometries and reconstructed the rates of ontogenetic change along the stem in mechanical properties across the simaruba clade in the tropical tree genus Bursera, measuring 376 segments from 97 branches in nine species in neotropical dry to rain forest.

Plasma amino acid levels discriminate between control subjects and mildly depressed elderly women.

Background And Aims: Depression is the most common of all psychiatric disorders and the role of amino acid transmitters in this pathology has been recently studied. We undertook this study to investigate if the plasma levels of L-arginine, L-citrulline, L-glutamic acid, L-glutamine, L-asparagine and other amino acids, the L-citrulline/L-arginine and the L-tyrosine/L-phenylalanine ratios, and the nitrite levels are modified in mildly depressed women and if such changes are related to olfactory dysfunction.

Methods: Plasma samples were obtained from elderly female subjects (n = 21) with mild depression and (n = 48) controls.

Universal foliage-stem scaling across environments and species in dicot trees: plasticity, biomechanics and Corner's Rules.

Trees range from small-leaved, intricately branched species with slender stems to large-leaved, coarsely branched ones with thick stems. We suggest a mechanism for this pattern, known as Corner's Rules, based on universal scaling. We show similar crown area-stem diameter scaling between trunks and branches, environments, and species spanning a wide range of leaf size and stem biomechanics.

[Parental influence in children's food preferences. The ESFUERSO study in two primary schools with different socioeconomic gradients].

Objective: Programs aimed at obesity prevention among elementary school age children have failed. In the present study, we analyzed the association between parental and child food preferences and determined whether this is influenced by the parents' gender and socio-economic status.

Material And Methods: We invited 300 children from a state elementary school (SES) and368 from a private middle class school (PMCS) to participate.
