RESUMEN

Resumen El objetivo de esta investigación fue estudiar la prevalencia de sobrepeso, obesidad y factores asociados en estudiantes de 5° y 6° grado de primaria en dos municipios de la Costa Chica de Guerrero. Se llevó a cabo un estudio descriptivo transversal. Para la recopilación de información se utilizó una báscula digital para registrar las medidas antropométricas y, se aplicó un cuestionario, que incluyó variables relacionadas con hábitos alimenticios, actividad física, tiempo dedicado a ver televisión (TV) y tiempo dedicado a dormir. Se encontró que el 16% de los estudiantes tuvo sobrepeso y 15% obesidad. Hubo mayor riesgo de padecer la enfermedad metabólica en los participantes que ven TV más de 5 h/día (ORns Cl adj = 1.72.IC 95% 1.27-2.34), mientras que comer cuatro o más veces al día tuvo un efecto protector (ORns Cl adj = 0.47, IC 95% 0.31-0.72). En los municipios de Cruz Grande y San Marcos los estudiantes de 5° y 6° de primaria tienen un grado medio de sobrepeso y obesidad; ya que el sedentarismo no es tan marcado y existe la tendencia a practicar el deporte. Se concluye que disminuir el número de horas frente al televisor y la correcta alimentación son acciones que pueden contribuir a la prevención y disminución del sobrepeso y la obesidad en estudiantes de primaria.


Abstract The objective of this research was to study the prevalence of overweight, obesity and associated factors in students of 5th and 6th grade of primary school in two municipalities of the Costa Chica, Guerrero. A crosssectional descriptive study was carried out. For the collection of information, a digital scale was used to record the anthropometric measurements and, a questionnaire was applied, which included variables related to eating habits, physical activity, time spent watching television (TV) and time spent sleeping. It was found that 16% of the students were overweight and 15% obese. There was an increased risk of metabolic disease in participants who watched TV more than 5 h / day (ORns Cl adj = 1.72.IC 95% 1.27-2.34), while eating four or more times a day had a protective effect (ORns Cl adj = 0.47, 95% CI 0.31-0.72). In the municipalities of Cruz Grande and San Marcos, students in grades 5 and 6 have a medium degree of overweight and obesity; since sedentary lifestyle is not as marked and there is a tendency to practice sports. It is concluded that reducing the number of hours in front of the television and the correct feeding are actions that can contribute to the prevention and reduction of overweight and obesity in elementary students.


Resumo O objetivo desta pesquisa foi estudar a prevalência de sobrepeso, obesidade e fatores associados em estudantes da 5ª e 6ª séries do ensino fundamental de dois municípios da Costa Chica de Guerrero. Foi realizado um estudo descritivo transversal. Para a coleta de informações, utilizou-se uma escala digital para registro das medidas antropométricas e aplicou-se um questionário, que incluiu variáveis relacionadas aos hábitos alimentares, atividade física, tempo gasto assistindo televisão (TV) e tempo gasto dormindo. Verificou-se que 16% dos estudantes estavam com sobrepeso e 15% com obesidade. Houve um risco aumentado de doença metabólica nos participantes que assistiram TV mais de 5 h / dia (ORns Cl adj = 1,72.IC 95% 1,27-2,34), enquanto comer quatro ou mais vezes por dia teve um efeito protetor (ORns Cl adj = 0,47, IC 95% 0,31-0,72). Nos municípios de Cruz Grande e San Marcos, os alunos das séries 5 e 6 apresentam sobrepeso e obesidade médios; uma vez que o estilo de vida sedentário não é tão acentuado e existe uma tendência a praticar esportes. Conclui-se que reduzir o número de horas em frente à televisão e a alimentação correta são ações que podem contribuir para a prevenção e redução do sobrepeso e obesidade em alunos do ensino fundamental.

RESUMEN

In all countries, the priority of policymakers is to reduce carbon emissions without reducing economic growth performance. Progress in innovation is one of the main measures that can be used to reduce carbon emissions. It is important to demonstrate the impact of innovation at the sectoral level, in terms of more realistic data on policy measures. The aim of this study is to investigate the effects of innovation on carbon emissions on a sectorial basis for fourteen countries in the G20, for the period between 1991 and 2017. The selected countries are Argentina, Brazil, Canada, France, Germany, India, Indonesia, Japan, Korea, Mexico, South Africa, Turkey, the United Kingdom, and the United States for which data is available. The results show that the Environmental Kuznets Curve (EKC) hypothesis is invalid and, in the long-term, innovations did not have a statistically significant effect on the energy sector, transport sector, and other sectors. It was also found that while an increase in innovation in the industrial sector leads to a reduction in carbon emissions, an increase in innovation in the construction sector increases carbon emissions. Therefore, it can be recommended that, in addition to national policies to reduce CO2 emissions, specific policies should be implemented for each sector separately.

RESUMEN

In April 2009, Mexican, American, and Canadian authorities announced a novel influenza that became the first pandemic of the century. We report on lessons learned in Mexico. The Mexican Pandemic Influenza Preparedness and Response Plan, developed and implemented since 2005, was a decisive element for the early response. Major lessons-learned were the need for flexible plans that consider different scenarios; the need to continuously strengthen routine surveillance programs and laboratory capacity and strengthen coordination between epidemiological departments, clinicians, and laboratories; maintain strategic stockpiles; establish a fund for public health emergencies; and collaboration among neighboring countries. Mexico responded with immediate reporting and transparency, implemented aggressive control measures and generous sharing of data and samples. Lessons learned induced changes leading to a better response to public health critical events.

RESUMEN

While functional traits can facilitate or constrain interactions between pair of species in ecological communities, relative abundances regulate the probabilities of encounter among individuals. However, the relative importance of traits and relative abundances for the role species play in seed dispersion networks remains poorly explored. Here, we analyzed 20 Neotropical seed dispersal networks distributed from Mexico to southeastern Brazil to evaluate how relative abundance and functional traits influence bat species' roles in seed dispersal networks. We tested how bat relative abundance and traits relate to species contribution to between-module (c metric) and within-module connectivity (z metric) and their position and potential to mediate indirect effects between species (betweenness centrality). Our results indicate that relative abundance is the main determinant of the role bats play in the networks, while traits such as aspect ratio show modest yet statistically significant importance in predicting specific roles. Moreover, all seed dispersal networks presented two or three superabundant obligatory frugivore species that interacted with a high number of plants. The modest influence of the functional traits on species' roles is likely related to the low variation of morphological traits related to foraging ecology, which reduces the chances of morphological mismatching between consumers and resources in the system. In this scenario, abundant bats have higher chances of encountering resources and being capable of consuming them which leads such species to play critical roles in the community by acting as module hubs and network connectors.

RESUMEN

COVID-19 has imposed unprecedented challenges to society. As the pandemic evolves, the social distancing measures that have been globally enforced, while essential, are having undesirable socioeconomic side effects particularly among vulnerable populations. In Mexico, families who depend upon informal employment face increased threats to their wellbeing, and households who in addition have young children may face long-term consequences. The Mexican government has not yet taken actions, but a coalition of non-governmental organizations is advocating in partnership with academic institutions for social protection actions such as a cash transfer and basic services subsidies for families with young children, subsisting from the informal sector economy. To facilitate governmental action, we estimated the costs for implementation of these recommendations. The methodology used could be replicated in other countries facing similar challenges.

RESUMEN

OBJECTIVE: To examine changes in categories of soft drink consumption in a cohort of Mexican adults, three years after the implementation of the sugar sweetened beverage tax. DESIGN: Open cohort longitudinal analysis. SETTING: Three waves of the Health Workers Cohort Study, Mexico, spanning 2004 to 2018. PARTICIPANTS: 1770 people aged 19 years or older with information on drinks consumption available in at least one of the three cohort waves. MAIN OUTCOME MEASURE: Change in probability of belonging to one of four categories of soft drinks consumption (non, low, medium, high) after the tax was implemented. Heterogeneity of associations by income and education was also assessed. RESULTS: Before the implementation of the tax, more than 50% of the participants were medium and high consumers of soft drinks and less than 10% were in the non-consumer category. After the tax was implemented, 43% of the population was categorised as medium or high consumers and the prevalence of non-consumers increased to 14%. Three years after implementation of the tax on 1 January 2014, the probability of being a non-consumer of soft drinks increased by 4.7 (95% confidence interval 0.3 to 9.1) percentage points and that of being a low consumer increased by 8.3 (0.6 to 16.0) percentage points compared with the pre-tax period. Conversely, the probability of being in the medium and high levels of soft drinks consumption decreased by 6.8 (0.5 to 13.2) percentage points and 6.1 (0.4 to 11.9) percentage points, respectively. No significant heterogeneity of the tax across income levels was observed, but stronger effects of the tax were seen in participants with secondary school education or higher, compared with those with elementary school or less. CONCLUSIONS: The Mexican sugar sweetened beverage tax was associated with a reduction in the probability of consuming soft drinks in this cohort of employees from a healthcare provider. The results cannot be extrapolated to the Mexican population, but they suggest that three years after implementation, the tax had helped to increase the proportion of people who do not consume soft drinks while decreasing the proportion of high and medium consumers.

RESUMEN

The environmental exposure to As, Se, Hg, Pb, Cr and toxaphene was assessed for 11 freshwater fish species in irrigation channels, agricultural return flow drains, a drain collecting lagoon and sections of the Colorado River at the Mexicali valley in Baja California, México, during August 2015-April 2016. Arsenic (2.90 ng ml-1) and Se (1.41 ng ml-1) in water had the highest concentrations in the return flow drains (Hardy River and Xochimilco Lagoon, respectively). However, fish axial muscle tissue had the highest concentration of Se (8.3 µg g-1) and Hg (0.36 µg g-1) in Colorado River fresh water, while As (1.7 µg g-1) in Hardy River fish was highest. Selenium concentrations in all fishes and toxaphene in Cyprinus carpio and Ameiurus natalis are above the safe levels for human consumption (0.3 µg g-1 and 180 ng g-1 respectively). Toxaphene was detected in the fish axial tissue, having the highest concentrations in Poecilia latipinna (690 ng g-1) in the Colorado River. The low proportion of the 8-Cl toxaphene congeners in fish suggests degradation of this pollutant. Tilapia. sp. cf. zillii had the most genotoxic damage with 7.4 micronucleated erythrocytes per 10,000 erythrocytes in Xochimilco Lagoon and 2 in Hardy River. The genotoxicity in all the fish species studied was significantly correlated to the concentrations of As and Se in water.

RESUMEN

Antimicrobial resistance is a global public health threat. Therefore, surveillance studies are important tools to help direct antimicrobial use. The aim of this study was to investigate antimicrobial resistance in Serratia marcescens isolates collected in 2016-2017 at eight medical centers from two regions of Mexico. Selected S. marcescens isolates were further tested by polymerase chain reaction to detect the presence of genes encoding the ß-lactamases, SHV, TEM or CTX. Antimicrobial resistance continues to be high in Mexico, particularly to ciprofloxacin and aminoglycosides. Also, a widespread prevalence of blaTEM was detected in S. marcescens isolates.

RESUMEN

PREMISE: Not all ferns grow in moist and shaded habitats. One well-known example is Notholaena standleyi, a species that thrives in deserts of the southwestern United States and Mexico. This species exhibits several "chemotypes" that differ in farina (flavonoid exudates) color and chemistry. By integrating data from molecular phylogenetics, cytology, biochemistry, and biogeography, we circumscribed the major evolutionary lineages within N. standleyi and reconstructed their diversification histories. METHODS: Forty-eight samples were selected from across the geographic distribution of N. standleyi. Phylogenetic relationships were inferred using four plastid and five nuclear markers. Ploidy levels were inferred using spore sizes calibrated by chromosome counts, and farina chemistry was compared using thin-layer chromatography. RESULTS: Four clades are recognized, three of which roughly correspond to previously recognized chemotypes. The diploid clades G and Y are found in the Sonoran and Chihuahuan deserts, respectively; they are estimated to have diverged in the Pleistocene, congruent with the postulated timing of climatological events separating these two deserts. Clade P/YG is tetraploid and partially overlaps the distribution of clade Y in the eastern Chihuahuan Desert. It is apparently confined to limestone, a geologic substrate rarely occupied by members of the other clades. The cryptic (C) clade, a diploid group known only from southern Mexico and highly disjunct from the other three clades, is newly recognized here. CONCLUSIONS: Our results reveal a complex intraspecific diversification history of N. standleyi, traceable to a variety of evolutionary drivers including classic allopatry, parapatry with or without changes in geologic substrate, and sympatric divergence through polyploidization.

RESUMEN

Nowadays, increasingly complex sets of indicators are used to compare and diagnose municipal solid waste management (MSWM). These sets incorporate new priorities regarding sustainability and focus on measuring the progress to zero waste. Nevertheless, in developing countries, where MSWM is still striving to protect health from the potential impacts of waste, the MSWM information available is scarce and of low quality. This work proposes a basic set of indicators for analyzing technical aspects of street cleaning, waste collection and disposal in such contexts. Based on the assessment of 66 Mexican municipalities, ten indicators were identified that can be calculated with the information available. For each indicator, reference values were established, and their performance was evaluated by means of a traffic light system. In addition, a method that allows the quality of the information to be classified into four levels according to the data source, its uncertainty, the temporal coverage, and its spatial coverage was applied. The results obtained revealed an incipient implementation of MSWM and highlighted the need to increase the coverage of the collection services and to improve the conditions of the disposal sites in most of the municipalities that were studied. The proposed set of indicators can be used as a starting point to systematize the monitoring and detection of areas of improvement in the MSWM of the municipalities studied, as well as in other systems in similar contexts.

RESUMEN

The diversity and community structure of arbuscular mycorrhizal fungi (AMF) associated with coconut (Cocos nucifera) roots was evaluated by next generation sequencing (NGS) using partial sequences of the 18S rDNA gene and by spore isolation and morphological identification from rhizosphere soil. Root samples from six different Green Dwarf coconut plantations and from one organic plantation surrounded by tropical dry forest along the coastal sand dunes in Yucatan, Mexico, were collected during the rainy and dry seasons. In total, 14 root samples were sequenced with the Illumina MiSeq platform. Additionally, soil samples from the dry season were collected to identify AMF glomerospores. Based on a 95-97% similarity, a total of 36 virtual taxa (VT) belonging to nine genera were identified including one new genus-like clade. Glomus was the most abundant genus, both in number of VT and sequences. The comparison of dry and rainy season samples revealed differences in the richness and composition of AMF communities colonizing coconut roots. Our study shows that the main AMF genera associated with coconut tree roots in all samples were Glomus, Sclerocystis, Rhizophagus, Redeckera, and Diversispora. Based on glomerospore morphology, 22 morphospecies were recorded among which 14 were identified to species. Sclerocystis sinuosa, Sclerocystis rubiformis, Glomus microaggregatum, and Acaulospora scrobiculata were dominant in field rhizosphere samples. This is the first assessment of the composition of AMF communities colonizing coconut roots in rainy and dry seasons. It is of importance for selection of AMF species to investigate for their potential application in sustainable agriculture of coconut.

RESUMEN

The complete genome sequence of a novel comovirus identified in Guanajuato, Mexico, in a common bean plant (Phaseolus vulgaris L.) coinfected with Phaseolus vulgaris alphaendornavirus 1 (PvEV-1) and Phaseolus vulgaris alphaendornavirus 2 (PvEV-2) is presented. According to the current ICTV taxonomic criteria, this comovirus corresponds to a new species, and the name "Phaseolus vulgaris severe mosaic virus" (PvSMV) is proposed for this virus based on the observed symptoms of "severe mosaic" syndrome caused by comoviruses in common bean. PvSMV is closely related to bean pod mosaic virus (BPMV), and its genome consists of two polyadenylated RNAs. RNA-1 (GenBank accession number MN837498) is 5969 nucleotides (nt) long and encodes a single polyprotein of 1856 amino acids (aa), with an estimated molecular weight (MW) of 210 kDa, that contains putative proteins responsible for viral replication and proteolytic processing. RNA-2 (GenBank accession number MN837499) is 3762 nt long and encodes a single polyprotein of 1024 aa, with an estimated MW of 114 kDa, that contains putative movement and coat proteins. Cleavage sites were predicted based on similarities in size and homology to aa sequences of other comoviruses available in the GenBank database. Symptoms associated with PvSMV include mosaic, local necrotic lesions, and apical necrosis. This is the first report of a comovirus infecting common bean in Mexico.

RESUMEN

Wine production has increased in recent years, especially in developing countries such as Mexico. This increase is followed by an increase of winery effluents that must be treated to avoid environmental risks. However, little information is available about the characteristics of these effluents and the possible treatments. This paper aimed to characterize the effluents and by-products generated by the Mexican winery industry and to evaluate the performance and stability of the anaerobic treatment using a single-stage and a two-stage process. Results showed that the winery effluents had a high content of biodegradable organic matter, with chemical oxygen demand (COD) values ranging from 221 to 436 g COD/L. The single-stage anaerobic process was able to treat an organic loading rate of 9.6 kg COD/(m3 d); however, it was unstable and highly dependent on the addition of bicarbonate alkalinity (0.31 g NaHCO3/g COD removed). The two-stage process was more stable working at a higher organic load (12.1 kg COD/(m3 d)) and was less dependent on the addition of bicarbonate (0.17 g NaHCO3/g COD removed). The results highlight the potential of the winery effluents to produce methane through anaerobic digestion in a two-stage process, making wine production more sustainable.

RESUMEN

Globally, adolescent pregnancy constitutes a serious public health problem of a multifactorial nature. Specifically for women, it entails various educational, economic and social implications that affect their life project and widen the social gaps in this age group. Furthermore, adolescent girls are more vulnerable because of the health risk involved with pregnancy at a younger age. According to the World Health Organization, "the probability of maternal death is twice as high in adolescents in comparison with women aged between 20 and 30 years, and for those younger than 15 years, the risks are five times higher". In general, adolescents are in great need for education on sexual and reproductive health issues, which should be aimed at increasing information and knowledge about correct use and access to modern contraceptive methods, as well as at demystifying fears and beliefs around their possible side effects. Ensuring proper counseling with trained personnel is equally vital. Public institutions have a social responsibility to support efforts aimed at preventing adolescent pregnancy, based on relevant lines of action and health policies.

RESUMEN

Introduction: In Mexico, there is an increase recorded in the number of C-sections, as well as inequity and inequality in the distribution of resources for obstetric care. Objective: To identify the states and municipalities in Mexico that concentrate the demand for obstetric care and the C-section rates and their relationship with health resources and women of childbearing age (WCBA). Method: Births of the 2008-2017 period were recorded, grouped into five municipal strata, as well as 2017 health resources and WCBA. Results: The 2008-2017 national rate of C-sections was 45.3/100 births; 95 and 97 % of births and C-sections were concentrated in the "very high" stratum, where 80 % or more of health resources were used, with overuse standing out. The density of health resources assigned to WCBAs reflected inequity and inequality. Conclusions: The high concentration of obstetric demand and health resources supply could entail a higher recurrence of C-sections. Policies for C-section reduction should consider proper organization and administration of health resources.

RESUMEN

Introduction: Children and adolescents weight and height are a reflection of the health status and socioeconomic development of a population. Objective: To evaluate height and weight progression patterns of Mexican children and compare them with Dr. Ramos-Galván growth charts 40 years later. Method: Cross-sectional survey conducted on the population of the National Physical Activation Program "Ponte al 100", which includes boys and girls aged six to 12 years. Results: 43,670 boys and 44,103 girls were assessed, stratified by gender and age. The height progression pattern between six and 12 years was 21 cm in males and 22 cm in females, whereas the weight progression pattern was 9.86 and 10.05 kg, respectively, for males and females. The proportion of six- and 12-year-old boys who were overweight was 11.2 and 9 %, while 14.7 and 15 % were obese. The proportion of six- and 12-year-old girls who were overweight was 8.2 and 9.1 %, whereas 21.7 and 13.3 %, respectively, were obese. When the obtained values were compared with those of Dr. Ramos Galván growth charts for boys and girls, the average difference was 2 cm. Conclusions: No secular height or weight increase within the last 40 years was documented.

RESUMEN

On December 31, 2019, the Chinese health authorities informed the international community, through the mechanisms established by the World Health Organization (WHO), of a pneumonia epidemic of unknown etiology in Wuhan, Hubei Province. The first cases were reported early in that month and were linked to a history of having visited a market where food and live animals are sold. On January 7, 2020, isolation and identification of the culprit pathogen was achieved using next-generation sequencing, while the number of affected subjects continued to rise. The publication of full-genomes of the newly identified coronavirus (initially called 2019-nCoV, now called SARS-CoV2) in public and private databases, of standardized diagnostic protocols and of the clinical-epidemiological information generated will allow addressing the Public Health Emergency of International Concern (PHEIC), declared on January 30 by the WHO. With this document, we intend to contribute to the characterization of the pneumonia epidemic, now designated coronavirus disease (Covid-19) review the strengths Mexico has in the global health concert and invite health professionals to join the preparedness and response activities in the face of this emergency.

RESUMEN

Objective: To assess the prevalence and dental erosion risk factors in Mexican schoolchildren. Study design: A transversal and analytical study was conducted on 411 children aged 6 to 12 years old in a public primary school of Mexico City. The children's parents answered a standardized questionnaire about their risk factors, and the Smith and Knight index was applied to assess their dental erosion degree. Results: The prevalence of dental erosion was 62%. The odds ratio and X2 tests revealed that probiotic beverage consumption (OR 1.658; CI 95%: 1.106-2.485; p = 0.014), sports beverages (OR: 2.807; CI 95%: 1.129-6.983; p = 0.021), natural juices (OR: 3.344; CI 95%: 1.556-7.184; p = 0.003), fruits and snacks with hot peppers and lemon (OR: 1.594; CI 95%: 1.066-2.382; p = 0.023), and syrups (OR: 1.869; CI 95%: 1.060-3.296; p = 0.029) were all risk factors for dental erosion. Conclusions: This study indicated that a high existence of dental erosion, which mainly affects the primary molars, is related to the frequent consumption of beverages and foods with acidic pH levels.
