This article examines caregivers' everyday language choices and interactions with children in an urban Zapotec community in Mexico, where Diidxazá is being displaced by Spanish in everyday use. It argues that caregivers' language choices and interactions get entangled in complex ways with the socio-cultural organization of everyday life and with local pedagogies and understandings of children's development, which, in turn, shape children's participation roles and long-term developmental trajectories as learners and speakers.

Halophytic plants grow in high salinity environments and present phytochemicals with antioxidant properties, such as phenolic compounds; due to the uncertain availability of healthy foods, there is a growing interest in their nutritional potential. However, their bioactive compounds with beneficial health effects are limited in their bioaccessibility. The objective of this study was to subject S. edulis and S. esteroa to an in vitro digestion process to evaluate the bioaccessibility and total antioxidant capacity of phenolic compounds during three phases of digestion. We determined phenolic compounds, flavonoids, and antioxidant capacity by colorimetric methods and phenolic composition by UHPLC-DAD. Total phenols, total flavonoids, and total antioxidant capacity by DPPH and TEAC in the three phases of digestion (oral, gastric, and intestinal) of S. esteroa were higher than in S. edulis, founding 4.84 % higher in total phenol content, and 0.05 % in total flavonoid content; also, and 28.94 and 23.93 % higher in total antioxidant capacity by DPPH and TEAC, respectively in the intestinal digestion phase. The bioaccessibility of S. edulis was higher than in S. esteroa; the intestinal was the phase reflecting more bioaccessible compounds. The bioaccessibility percentages of total phenols and flavonoids were 590.16 and 1012.93 %, and the percentage recovery of total antioxidant capacity by DPPH and TEAC were 181.37 and 139.74 %. We identified phenolic acids ferulic, p-Coumaric, and synaptic (hydroxycinnamic), gallic and protocatechuic (hydroxybenzoic), the flavonoids catechin (flavan-3-oles), myricetin and ruthin (flavonols), naringenin and naringin (flavonones). S. esteroa presented bioactive compounds in higher concentrations than S. edulis due to the stress imposed by its habitat; nevertheless, the determined bioactive compounds of S. edulis showed a higher bioaccessibility because it was managed under local improvement.

Spinocerebellar ataxia 19 (SCA19) represents a rare autosomal dominant genetic disorder resulting in progressive ataxia and cerebellar atrophy. SCA19 is caused by variants in the KCND3 gene, which encodes a voltage-gated potassium channel subunit essential for cerebellar Purkinje cell function. We describe six cases from Chile and Mexico, representing the largest report on SCA19 in Latin America. These cases encompass a range of clinical presentations, highlighting the phenotypic variability within SCA19 from an early-onset, severe disease to a late-onset, slowly progressive condition with normal lifespan. While some patients present with pure ataxia, others also show cognitive impairment, dystonia, and other neurological symptoms. The correlations between specific KCND3 variants and phenotypic outcomes are complex and warrant further investigation. As the genomic landscape of spinocerebellar ataxias evolves, comprehensive genetic testing is becoming pivotal in improving diagnostic accuracy. This study contributes to a better understanding of the clinical spectrum of SCA19, laying the groundwork for further genotype-phenotype correlations and functional studies to elucidate the underlying pathophysiology.

Background Public health officials are responding to an outbreak of fungal meningitis among patients who received procedures under epidural anesthesia at 2 clinics (River Side Surgical Center and Clinica K-3) in Matamoros, Mexico, during 1 January to 13 May 2023. This report describes outbreak epidemiology and outlines interim diagnostic and treatment recommendations. Methods Interim recommendations for diagnosis and management were developed by the Mycoses Study Group Research Education and Consortium (MSGERC) based on the clinical experience of clinicians caring for patients during the current outbreak or during previous outbreaks of healthcare-associated fungal meningitis in Durango, Mexico, and the United States. Results As of 7 July 2023, the situation has evolved into a multistate and multinational fungal meningitis outbreak. A total of 185 residents in 22 US states and jurisdictions have been identified who might be at risk of fungal meningitis because they received epidural anesthesia at the clinics of interest in 2023. Among these patients, 11 suspected, 10 probable, and 10 confirmed US cases have been diagnosed, with severe vascular complications and 8 deaths occurring. Fusarium solani species complex has been identified as the causative agent, with antifungal susceptibility testing of a single isolate demonstrating poor in vitro activity for most available antifungals. Currently, triple therapy with intravenous voriconazole, liposomal amphotericin B, and fosmanogepix is recommended. Conclusions Efforts to understand the source of this outbreak and optimal treatment approaches are ongoing, but infectious diseases physicians should be aware of available treatment recommendations. New information will be available on the Centers for Disease Control and Prevention's (CDC's) website. [ABSTRACT FROM AUTHOR]

We summarize the clinical trials (CTs) main characteristics, including members of ethnic minorities from Latin America. We carried out a systematic search in six databases. We made a descriptive synthesis of CTs, summarizing the characteristics, interventions, main findings, results, and conclusions reported. 4411 studies were acquired in search strategy, leaving 24 CTs in the final selection. Of these, ten were randomized, four were non-randomized, and the remainder had other designs. Most of the studies were carried out in the population of infants and children (08), ten of the studies included only women, and two studies included men. Nine studies were conducted in Mexico, with the Mayan ethnic minority being mostly evaluated (05). In only 15 it was mentioned that their research was approved by a research ethics committee. Finally, half of the CTs reported funding from international agencies and third reported funding from government agencies. Our results show that that CTs in ethnic minorities are limited and reduced to a few native peoples of the continent. [ABSTRACT FROM AUTHOR]

Breeding seabirds must balance the energetic demands of feeding themselves and their offspring while coping with the constraints imposed by central-place foraging. As such, foraging strategies and parental care patterns are usually linked. Here, the foraging behavior of the Red-billed Tropicbird (Phaethon aethereus; n = 161) of Peña Blanca Islet, Mexico (19° 06ʹ 11ʺ N, 104° 29ʹ 12ʺ W) during the incubation and chick-rearing (≤ 4 weeks of age) stages was characterized with the aid of GPS loggers. Blood samples from adults and chicks were collected to determine δ15N and δ13C, and parental presence at the nest, meal size, and parent-chick feeding events were recorded. During incubation, parents made long trips offshore to areas far from the colony; however, immediately after their chicks hatched, the parents switched to a bimodal foraging strategy by undertaking both short and long foraging trips. The δ15N values indicated that trophic differences were present between parents and their offspring, with chicks being fed prey enriched in 15N. Parental presence at the nest was greater during early chick-rearing, which was associated with a higher provisioning rate. Parents adopted a strategy in which the parent on nest duty only made short foraging trips to provide for its offspring without leaving it unattended for long periods, while its mate undertook long trips to feed itself. After the early chick-rearing period, the parents gradually reduced the time spent at the nest and increased the time spent foraging, compensating with larger meal sizes for their offspring.

Theobroma bicolor Bonpl. 1806 is distributed in the Neotropics from southern Mexico to the Peruvian and Brazilian Amazon. High-throughput sequencing of T. bicolor from Peru (KUELAP2926) resulted in the assembly of its complete plastid genome (GenBank accession number OQ557154). The chloroplast genome of T. bicolor is A + T-rich (62.97%), having 160,317 bp in size and containing 130 genes; including a pair of inverted repeat regions (IRs) of 25,462 bp separated by a large single copy region (LSC) of 89,221 bp and a small single copy region (SSC) of 20,172 bp. This plastid genome is similar in length, content, and organization to other members of the genus Theobroma. Phylogenetic analyses of T. bicolor support its sistership to the clade comprising T. cacao and T. grandiflorum. This study may contribute valuable information to the phylogenetic relationships within the genus Theobroma. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic presents global health, welfare, and economic concerns. The agricultural workforce has experienced adverse effects, placing the U.S. food supply at risk. Agricultural workers temporarily travel to the United States on H-2A visas to supplement the agricultural workforce. Approximately 300,000 agricultural workers enter the United States with H-2A visas each year; over 90.0% are from Mexico. During February–May 2021, a COVID-19 testing pilot was performed with Clínica Médica Internacional (CMI), a clinic that performs medical examinations for US-bound immigrants, to determine the SARS-CoV-2 infection status of H-2A agricultural workers in Mexico before entry to the US. The CerTest VIASURE Real Time PCR Detection Kit was used. Participants' demographic information, test results, and testing turnaround times were collected. Workers who tested positive for SARS-CoV-2 completed isolation before US entry. During the pilot, 1195 H-2A workers were tested; 15 (1.3%) tested positive. Average reporting time was 31 h after specimen collection. This pilot demonstrated there is interest from H-2A employers and agents in testing the H-2A community before US entry. Testing for SARS-CoV-2 can yield public health benefit, is feasible, and does not delay entry of temporary agricultural workers to the US. [ABSTRACT FROM AUTHOR]

Protected areas are under immense pressure to safeguard much of the remaining global biodiversity and can be strained by unpredicted events such as the Covid-19 pandemic. Understanding the extent of the effects of the pandemic on protected area management and conservation outcomes is critical for recovery and future planning to buffer against these types of events. We used survey and focus group data to measure the perceived impact of the pandemic on protected areas in Mexico and outline the pathways that led to these conservation outcomes. Across 62 protected areas, we found substantial changes in management capacity, monitoring and tourism, and a slight increase in non-compliant activities. Our findings highlight the need to integrate short-term relief plans to support communities dependent on tourism, who were particularly vulnerable during the pandemic, and to increase access to technology and technical capacity to better sustain management activities during future crises.

Brief alcohol advice offered to patients was shown to be a clinically- and cost-effective intervention to prevent and manage alcohol-related health harm. However, this intervention is not yet optimally implemented in practice. A suggested strategy to improve the implementation of brief alcohol advice is through community actions which would enhance the environment in which primary healthcare providers must deliver the intervention. However, there has been scarce research conducted to date regarding which community actions have most influence on the adoption and implementation of brief alcohol advice. The current protocol presents the development of a package of community actions to be implemented in three Latin American municipalities, in Colombia, Mexico and Peru. The community actions were based on the Institute for Health Care Improvement's framework for going to full scale, and include: (i) involvement of a Community Advisory Board, (ii) involvement of a project champion, (iii) adoption mechanisms, (iv) support systems and (v) a communication campaign. By presenting a protocol for developing community actions with input from local stakeholders, this article contributes to advancing the public health field of alcohol prevention by potentially stimulating the sustainable adoption and implementation of brief alcohol advice in routine practice.

The European Union (EU) is renegotiating its trade agreements with Latin American States. The core objective of this process is to modernize the Trade and Sustainable Development (TSD) chapters of these agreements. As such, this article critically examines the prospects of the modernized TSD chapters in the Chile-EU Association Agreement and the EU-Mexico Global Agreement, drawing lessons for the potential amendment of the EU-Andes Agreement. For this purpose, the article addresses the modernization process of the EU-Chile Association Agreement by surveying Chile's negotiating practice in incorporating environment and climate change-related provisions in trade agreements. It compares the evolution of these provisions within the EU's practice and discusses the convergence or divergence of views that have shaped the existing agreement. Additionally, it explores the possible future review process of the TSD chapter in the agreement. Furthermore, the article discusses the ongoing renegotiating process of the Global Agreement between the EU and Mexico. It examines the opportunity to enhance the current environmental protection disciplines in this agreement. Finally, the article evaluates how these experiences can inform a future renegotiation of the EU-Andes Agreement, with a focus on prioritising the Parties' nationally determined contributions (NDCs) under the Paris Agreement.

The study analyzed the dynamics of grazing in sheep production associated with agricultural crops based on the social, productive, market, income, and environmental dimensions in the temperate region of Puebla and Tlaxcala, Mexico. The use of grazing, topography, climate, crops and type of vegetation in the production systems and data on the family, means of production, market and income were recorded with interviews applied to 256 sheep producers. Data were analyzed with descriptive statistics and response surface linear regression models and multilevel models, with the SAS statistical package. Five crop and sheep associations were defined as results. The response surface linear regression models, fitted for grazing percentage, had differences in the slopes estimated (P<0.05) for producer experience, schooling, days of work spent on sheep, value of facilities and flock size. The multilevel analysis showed that 19 % of the variance in grazing time (hours) was explained by the variables of crop and sheep associations (level 2) and the rest by production units (level 1). Multilevel models associated grazing time with income (P<0.01), percentage of lamb sales (P<0.01), schooling (P<0.05), days of work spent on sheep (P<0.05), flock size P<0.05) and grazing percentage (P<0.001). The study allowed the classification of agroecosystems and the identification of the most appropriate profile of producer for sheep production in the socioecological and economic context in the temperate region of Puebla and Tlaxcala, Mexico.

Levels of cultural understanding can be applied to leadership and research. Intracultural understanding is self-contained within one culture. Cross-cultural understanding extends from one culture to another. Intercultural understanding recognizes implications for one's own culture. Metacultural understanding extends beyond one's own and others' culture to create entirely new meanings. This study examines an educational administration program in Mexico using researchers from a multicultural team. School directors and those in higher education participated in focus groups to examine the preparation Mexican leaders receive, the challenges they face, and the implications for preparation programs. These issues are significant in Mexico, and have implications for the United States and other countries.

Objective: To present the characteristics of wine tourism that takes place in the states of Querétaro and Baja California, Mexico. Design/methodology/approach: Descriptive analysis through primary sources of information where 228 questionnaires were applied to those who carried out wine tourism in the states of Querétaro and Baja California, or who in the last three years have carried out this activity in Mexico. Results: The survey respondents reflect interest in the knowledge, production and culture of wine. In addition, they state that the wine routes in the study areas give them satisfaction in the price-quality ratio, wine tastings and gastronomy and that these are key to the development of viticulture in Mexico. Limitations on study/implications: People feel that they do not have enough knowledge about wine tourism, which limited their participation when answering the questionnaire. However, this work is a first approximation to carry out a study that relates wine tourism and the competitiveness of the wine industry in Mexico, for which the answers are timely. Findings/conclusions: Mexican wine is considered to have the potential to compete with foreign wines in factors such as quality, flavor and price. In addition, there is a preference for the consumption of Mexican wines, especially red, rose and white. Therefore, the wine production from states such as Chihuahua, Sonora, Coahuila and Durango, which have a large territorial extension, should be taken advantage of, and more commercial wine routes should be created to help promote this industry at the national level to improve society through greater offer, job creation and reduction of imports.

Background: Cross-border use of health services is an important aspect of life in border regions. Little is known about the cross-border use of health services in neighboring low- and middle-income countries. Understanding use of health services in contexts of high cross-border mobility, such as at the Mexico-Guatemala border, is crucial for national health systems planning. This article aims to describe the characteristics of the cross-border use of health care services by transborder populations at the Mexico-Guatemala border, as well as the sociodemographic and health-related variables associated with use. Methods: Between September-November 2021, we conducted a cross-sectional survey using a probability (time-venue) sampling design at the Mexico-Guatemala border. We conducted a descriptive analysis of cross-border use of health services and assessed the association of use with sociodemographic and mobility characteristics by means of logistic regressions. Results: A total of 6,991 participants were included in this analysis; 82.9% were Guatemalans living in Guatemala, 9.2% were Guatemalans living in Mexico, 7.8% were Mexicans living in Mexico, and 0.16% were Mexicans living in Guatemala. 2.6% of all participants reported having a health problem in the past two weeks, of whom 58.1% received care. Guatemalans living in Guatemala were the only group reporting cross-border use of health services. In multivariate analyses, Guatemalans living in Guatemala working in Mexico (compared to not working in Mexico) (OR 3.45; 95% CI 1.02,11.65), and working in agriculture/cattle, industry, or construction while in Mexico (compared to working in other sectors) (OR 26.67; 95% CI 1.97,360.85), were associated with cross-border use. Conclusions: Cross-border use of health services in this region is related to transborder work (i.e., circumstantial use of cross-border health services). This points to the importance of considering the health needs of migrant workers in Mexican health policies and developing strategies to facilitate and increase their access to health services.

Objective: To analyze the influence of international trade on the specialization and competitiveness of Mexican chicken meat during 1980 to 2017. Methodology: A hypothetical-deductive method was applied; the study is longitudinal with information from secondary sources with which it was developed. a database in Excel in the form of matrices to calculate the competitiveness indices at the macroeconomic level, which are: the Lafay and Balassa index. Results: The results show that Mexico lacks comparative advantages and must generate strategies for infrastructure, health regulation and strengthening of the productive chain to increase production, reduce costs and thereby increase its specialization and competitiveness as a net exporter. Limitations: Is necessary to disseminate, by the institutional route and in collaboration with private and nongovernmental organizations, the best agricultural practices and at the same time, stimulate the development of the improved seed market. Conclusions: It is necessary to carry out actions that increase the advantages and with it the specialization and competitiveness in the commercial poultry farming of chicken meat.

The goal of this research is to interpret the magnetic and gravimetric responses subsurface in the western portion of the Grijalva basin, Mexico, in order to identify and delimit the areas of rock units with aquifer potential. For it, the processing of satellite aeromagnetic and gravimetric data was carried out with the purpose of delimiting the geological characteristics of greatest interest. The results show that the north-central part of the study portion represents the area with the greatest aquifer potential, and it coincides with the areas of greater sedimentary thickness, of lower altitude, and where the groundwater concessions are concentrated. Therefore, the change of gradients between magnetic and gravimetric responses contributes to the knowledge of the structural framework (faults, fractures, edges, and geological contacts) and the inference of areas with aquifer potential. In detail, from the filters used, the Tilt Derivative (TDR) presents the linear trends associated with the structural framework of a specific water interest. It seeks to promote decision-making and research on geohydrological topics, territorial planning, and related public policies. [ABSTRACT FROM AUTHOR]

Payments for hydrological services (PHS) apply an incentive-based approach to achieve conservation and socioeconomic goals. PHS policies are most successful when they are designed and implemented with participation from diverse stakeholders and respond to local needs and conditions. Role-play simulations (RPS) engage stakeholders from different organizations and decision-making roles in policy deliberations and innovations. This paper explores how a science-based RPS encourages participation from diverse actors to inform PHS policy innovation in Veracruz, Mexico. We present results from two RPS workshops which engaged 69 stakeholders in negotiations on the future design of a hypothetical PHS program. Our RPS integrated qualitative and quantitative information from operating PHS programs to inform a hypothetical, but realistic, decision-making scenario. This paper analyzes data collected from surveys of workshop participants, audio recordings of workshop discussions, and post-workshop, in-depth interviews. We found the RPS fostered collaborative decision-making by engaging participants in constructive conversations about PHS program design options to effectively contribute to forest conservation and socioeconomic well-being, including incentivizing environmentally friendly farm practices and complementing cash payment with in-kind transactions. We also found the collaborative method of RPS challenged the exclusive role of technical expertise in decision-making by eliciting ideas for improvement of PHS programs and fostering understanding and empathy towards others and their interests, particularly for small landowners who do not typically participate in decision-making. We conclude that a science-based RPS can be a valuable tool for encouraging multi-stakeholder participation in policy design that reflects local environmental and socio-economic values and needs. • Role-play simulation (RPS) is a method to engage stakeholders in policy deliberations and innovation. • RPS promotes critical thinking about the design and approach of PHS policy. • RPS can potentially inform PHS policies. • RPS negotiations can contribute to mutual understanding between different stakeholders. • RPS negotiations can be a valuable tool for encouraging multi-stakeholder participation in generating policy options.

Mendelian susceptibility to mycobacterial disease (MSMD) is a rare genetic disorder characterized by impaired immunity against intracellular pathogens, such as mycobacteria, attenuated Mycobacterium bovis-Bacillus Calmette–Guérin (BCG) vaccine strains, and environmental mycobacteria in otherwise healthy individuals. Retrospective study reviewed the clinical, immunological, and genetic characteristics of patients with MSMD in Mexico. Overall, 22 patients diagnosed with MSMD from 2006 to 2021 were enrolled: 14 males (64%) and eight females. After BCG vaccination, 12 patients (70%) developed BCG infection. Furthermore, 6 (22%) patients developed bacterial infections mainly caused by Salmonella, as what is described next in the text is fungal infections, particularly Histoplasma. Seven patients died of disseminated BCG disease. Thirteen different pathogenic variants were identified in IL12RB1 (n = 13), IFNGR1 (n = 3), and IFNGR2 (n = 1) genes. Interleukin-12Rβ1 deficiency is the leading cause of MSMD in our cohort. Morbidity and mortality were primarily due to BCG infection. [ABSTRACT FROM AUTHOR]

Detailed studies about energy content and chemical characterization of biomass alternatives are necessary to determine their main features as solid fuels. The aim of this study was to analyze and compare the properties of five types of residual biomass pellets produced throughout Mexico: sawmill pine waste (SPW), spent ground coffee (SGC), pecan nutshell (PN), oil palm waste (OPW), and mango waste (MW). Conventional characterization analyses revealed significant differences in HHV (21.44–17.37 MJ/kg), elemental composition showed a lower carbon content in SPW and MW (around 46%), OPW (close to 47%), and higher carbon content in PN and SGC (around 51%). The concentration of the main structural polymers showed notable significant differences (p < 0.05) too: 49–17% for cellulose, for hemicellulose 21–5% and for lignin 26–4%. High-throughput instrumental techniques were also used: FTIR provided additional information on chemical composition in pellets on which lignocellulosic biomass was not predominant, presence of pectins and starch in MW, and high content of fatty acids in SGC and OPW; TGA showed different thermal stability of pellets in the combustion process, where OPW and SPW presented the lowest and highest thermal stability, respectively, while XPS showed different types of bonds between C and O in the surface of materials with a relevant presence of bonds associated to lignin covering PN and SPW. Based on results of this investigation, a possible rank for the energy use of these five biomasses is suggested: PN, SPW, SGC, OPW, and MW, but future deep research is necessary that incorporate other relevant attributes, mechanical properties, emission profiles, corrosion, and slagging effects.

This study applies environmental life cycle assessment to quantify and compare the environmental profile of the production and use of wood pellets for residential heating (baseline) and compares the pellet system with two different alternative systems for residential heating in Mexico: (1) the use of LPG heater and (2) one electricity heater powered by three different sources of electricity. The baseline system boundaries include the stages of forest management, transportation, industrial, distribution, wood pellet energy conversion, and ash management. First-hand data and measurements of the emission profiles in the field and laboratory were developed. The functional unit was 1 MJ of thermal energy for residential heating. Environmental impacts were calculated for six impact categories from the ReCiPe midpoint method. Furthermore, a sensitivity analysis was performed to evaluate the influence of the allocation criteria (mass and economic) as well as adopting different values for the electricity sources (system's hotspots). The results obtained for each impact category show a relatively wide range of variation when the five scenarios of the heating systems are compared and analyzed. Electricity heater powered with photovoltaic electricity is better for all the impact categories analyzed. The performance of pellets and LPG is very close, but the pellets have lower impacts on global warming (three times), fossil resource scarcity (four times), and acidification. Therefore, the use of pellets in an efficient boiler is a promising option for residential heating. [ABSTRACT FROM AUTHOR]

Simple Summary: The effect of social rank (i.e., low or high) in adult Dorper rams on sexual behavior, body condition score, seminal quality, and whole blood count was evaluated. The high-social-ranked Dorper rams displayed more sexual behaviors compared with low-social-ranked rams. In parallel, high-social-ranked rams had a higher body condition score and a larger ejaculate volume compared with low-social-ranked rams; they also showed an optimal health and wellness status, reflected by the whole blood count. Such behavioral, metabolic, sexual, seminal, and health advantages shown by the high-social-ranked Dorper rams must be taken into account to avoid reproductive failures. While there is still limited evidence on the role that social rank plays in out-of-season reproductive success, this study helps to better comprehend how social dominance is associated with male-to-male competitiveness, male-to-female sexual behavior, seminal quality, and blood cell components, and how their interaction with each other modulates and even determines out-of-season reproductive success in Dorper rams. Dorper rams (n = 24) were evaluated during the sexual resting season to determine their social rank (SR), either high (HSR) or low (LSR), under intensive management conditions in northern Mexico (25° N). Aggressive behaviors were quantified during male-to-male interactions, and appetitive and consummatory sexual behaviors during male-to-female interactions. Morphometric, live weight (LW), and body condition score (BCS) were recorded. During the early reproductive season, male-to-female behaviors were newly itemized simultaneously by seminal quality and quantity sampling. Finally, the dependent variables of the hemogram components were also quantified. Neither LW (61.25 ± 2.4 kg) nor morphometric variables differed between SR groups. However, BCS (2.25 vs. 2.66 u), sexual behaviors (i.e., approaches: 59.6 vs. 21.73 n, mating with ejaculation: 77.7 vs. 42.86 %, latency to ejaculation: 16.6 vs. 143.07 s), ejaculate volume (0.57 vs. 0.23 mL), and hemogram components favored the HSR rams (p < 0.05). Moreover, in their first male-to-female interaction, >50% of the LSR rams failed to display any sexual activity. HSR rams displayed a greater number of threatening behaviors, managing to displace LSR rams when exposed to estrus ewes during the male sexual resting season; more sexual behaviors; and an increased seminal volume in a non-live weight-dependent fashion.

Payment for ecosystem services (PES) is a prominent neoliberal, market-based environmental policy tool to promote conservation of biodiversity and ecosystem services (ES) that has been applied since the late 1990s in both industrialized and developing countries. Recent studies have documented how PES programs do not actually function as market-based programs, and that they are often modified on the ground by local actors. Adding to this literature, our study uses an actor-oriented approach to examine how local actors in Veracruz, Mexico respond to and make changes to payment for hydrological services (PHS) programs, a prominent PES program used to address water quality and quantity issues. Drawing on interviews with 15 institutional actors and 58 landowners, we investigate how these actors challenge and modify these programs to make them more responsive to local socioecological conditions and needs. Our argument is that situated knowledge about land uses and socioecological conditions, and norms of equity and fairness, play central roles in empowering social actors to alternately adopt, contest, and re-shape PHS programs to better meet local conditions and needs. • Actor-Oriented approach to Payment for Ecosystem Services (PES) programs. • Local knowledge, values and norms reshape PES programs to be more responsive to local socioecological conditions and needs. • Qualitative research to explore situated agency of local actors in market-based conservation policies in the global south.

The Huasteca Potosina region has a relevant landscape heritage of biocultural diversity, due to high biological diversity and the presence of the Teenek (Huastec Mayan), Nahua, and Xi'iuy (Pame) ethnic groups. The object of this study is to analyze, among the different cultural groups of the region, how the performances of the relevant Socioecological Systems (SESs) influence the conservation of biocultural diversity. Quantitative approaches are used to determine the expected trends of indices (Informant Consensus Factor, ICF; Cultural Importance Index, CII; Shannon–Wiener Biodiversity Index, SWI) commonly used in the ethnobotanical field. Data of the main domestic forest species used by the groups mentioned above were collected in 2021. We analyzed the SES profile for each of the ethnic groups and a mestizo group, as well as their relationship with the biome they mainly inhabit and the domestic functions fulfilled by the ethnobotanical species. As a result, we found that the low deciduous forest and the sub-evergreen tropical forest biomes, which co-evolved mainly with the Nahua and the Teenek SESs, present higher diversity and effective use of species so that offer better chances for conserving the landscape heritage of biocultural diversity. Otherwise, the results also show the critical nature regarding the biomes inhabited by the Pame and the mestizo's SESs. [ABSTRACT FROM AUTHOR]

The study of the financial system, within the context of a Social Accounting Matrix, to identify its potential contribution to the economy and the linkages between the financial and productive sectors, is a topic barely explored, especially in emerging economies. This paper presents the construction of a Financial Social Accounting Matrix for the case of Mexico for the year 2013, using the Top-Down approach. It also presents an analytical tool through multipliers and impact simulations to understand the interconnection of income and expenditure transactions between sectors of the economy, into the intersectoral framework of financial sector flows and funds, identifying which sectors are creditors or debtors. We find that despite encouraging strategic sectors and allocating income to financial companies, the impact generated on other productive sectors is weak. Real estate services is the subsector that generates more monetary units for each exogenous monetary unit received. The methodology can be applied to assess the effects of impact simulations for planning policy, such as knowing the strategic sectors of the economy with greater linkages, and the possibility to assign and redirect financing to promote the consumption and investment capacity of both companies and households.

Purpose: Differences in metformin effect on glycemic control in type 2 Diabetes (T2D) have been associated with diet, obesity, years since T2D diagnosis and genetic factors, such as the Met408Val (rs628031) SLC22A1/OCT1 gene polymorphism. This study aimed to analyze the effect of metformin and diet on glycemic control and its association with the Met408Val polymorphism in patients with T2D from western Mexico. Patients and Methods: A total of 240 T2D adult patients were enrolled in this cross-sectional study. Anti-hyperglycemic therapy, dietary intake, body composition and glycemic profile were recorded and the determination of genotypes of SLC22A1/OCT1 gene (rs628031) was performed using an allelic discrimination assay. Results: The type of metformin therapy was 47% monotherapy, 45% dual therapy (metformin+glibenclamide or metformin+insulin) and 8% triple therapy (metformin+glibenclamide+insulin). Individuals with metformin monotherapy had a higher glycemic control frequency (%HbA1c < 7.0) compared with the dual and triple treatment schemes (77% vs 35% and 15%, respectively; p< 0.001). Interestingly, a high potassium intake was documented in the three anti-hyperglycemic therapies and a lower intake of micronutrients, including calcium, magnesium, and zinc. An interaction was found between calcium intake and carriers of the risk allele A (408Val) with %HbA1c (P interaction=0.028), and potassium intake with the TyG index (P interaction=0.027). In addition, there was a positive correlation between calcium intake and %HbA1c (r=0.682; p=0.010), and potassium intake vs TyG index (r=0.593; p=0.033) in risk allele A (408Val) carriers with metformin monotherapy. Genotype frequencies were GG homozygotes (76.6%), GA heterozygotes (21.5%) and AA homozygotes (1.9%). The allele frequency was 87.4% for the ancestral allele G and 12.6% for the risk allele A. Conclusion: These findings suggest a differing effect of metformin on glycemic control regarding calcium and potassium intake and the Met408Val SLC22A1/OCT1 gene polymorphism in T2D patients.

Because English is an integral component of education in Mexico, it is necessary to explore teachers' language assessment literacy (LAL), or their language assessment knowledge and practices. Previous LAL studies have been performed in standardized testing-focused. However, the present study aims to explore the LAL of teachers of middle school English students in a context where governmental policies strive to engender communicative language learning, specifically, Mexico. I have taken a mixed methods approach which involved a survey (N = 123) and interviews at two locations in Mexico. The semi-structured interviews were conducted at one bilingual middle school (N = 7) and in one extracurricular English program (N = 6). Participants were asked about their previous training, confidence levels in their assessment practices, and their training needs. Findings suggest a divide among teachers with higher and lower levels of LAL. Participants indicated that their training primarily covered traditional forms of assessment and classroom-level decision-making. However, data also suggest that participants valued non-traditional assessment activities. Finally, participants desired training on topics such as the use of technology in assessment, unfamiliar non-traditional assessment activities, and program-level decision-making.

COVID-19 has disproportionally affected underrepresented minorities (URM) and low-income immigrants in the United States. The aim of the study is to examine the underlying vulnerabilities of Mexican immigrants in New York City (NYC) and Los Angeles (LA), its correspondence with area-level COVID-19 morbidity and mortality, and to document the role of trusted and culturally sensitive services offered during the pandemic through the Ventanillas de Salud (i.e. VDS, Health Windows) program. The study uses a mixed-methods approach including a cross-sectional survey of Mexican immigrants in LA and NYC collected in the Mexican Consulates at the onset of the pandemic, complemented with a georeferencing analysis and key informant interviews. Data suggested an increased vulnerability to COVID-19 given participants reported health status, health care profile and place of residence, which coincided with the georeferencing analysis. The key informant interviews confirmed the vulnerability of this population and the supporting role of VDS in helping immigrants navigate health systems and disseminate health information. Mexican immigrants had an increased vulnerability to COVID-19 at the individual, geographic and systemic levels. Trusted and culturally sensitive services are needed to overcome some of the barriers and risk factors that increase the vulnerability of URM and immigrant populations to COVID-19.

Alcohol measurement delivered by health care providers in primary health care settings is an efficacious and cost-effective intervention to reduce alcohol consumption among patients. However, this intervention is not yet routinely implemented in practice. Community support has been recommended as a strategy to stimulate the delivery of alcohol measurement by health care providers, yet evidence on the effectiveness of community support in this regard is scarce. The current study used a pre-post quasi-experimental design in order to investigate the effect of community support in three Latin American municipalities in Colombia, Mexico, and Peru on health care providers' rates of measuring alcohol consumption in their patients. The analysis is based on the first 5 months of implementation. Moreover, the study explored possible mechanisms underlying the effects of community support, through health care providers' awareness of support, as well as their attitudes, subjective norms, self-efficacy, and subsequent intention toward delivering the intervention. An ANOVA test indicated that community support had a significant effect on health care providers' rates of measuring alcohol consumption in their patients (F (1, 259) = 4.56, p = 0.034, ηp2 = 0.018). Moreover, a path analysis showed that community support had a significant indirect positive effect on providers' self-efficacy to deliver the intervention (b = 0.07, p = 0.008), which was mediated through awareness of support. Specifically, provision of community support resulted in a higher awareness of support among health care providers (b = 0.31, p < 0.001), which then led to higher self-efficacy to deliver brief alcohol advice (b = 0.23, p = 0.010). Results indicate that adoption of an alcohol measurement intervention by health care providers may be aided by community support, by directly impacting the rates of alcohol measurement sessions, and by increasing providers' self-efficacy to deliver this intervention, through increased awareness of support.

The objective was to implement a participatory process involving rescue and conservation of Creole goats in agro-silvopastoral systems, as a development strategy for the indigenous and marginalized region of the Mountains of Guerrero (MG), Mexico. The study focused on the caprine agroecosystem, documenting aspects of goat development and identifying caprine areas in 13 municipalities, zoometrically characterizing 680 goats. One hundred and ten goat producers were interviewed for evaluating farmer perception of goat production. Fifty-seven producers were trained in holistic management, and four producers raised 300 goats in outstanding herds. Data were analyzed using social networks, principal component analysis and correspondence analysis. Two goat agroecosystems were identified: 1) agro-silvopastoralism, with crossbreeding of goat populations and, 2) traditional systems, involving grazing of Creole goats on native vegetation. We identified three types of goats: 1) Mixteco mosaic (61%), 2), Pastoreña (31.8%), and 3) Crossbreeds (7.2%), based on bicoastal diameter, chest depth, body length, thoracic perimeter, height at withers, shoulder point width and liveweight. Smallholder goat farmers in the MG preferred Creole goats for their greater productivity and better environmental adaptation. [ABSTRACT FROM AUTHOR]

Effective interventions exist for heavy drinking and depression but to date there has been limited translation into routine practice in global health systems. This evidence-to-practice gap is particularly evident in low- and middle-income countries. The international SCALA project (Scale-up of Prevention and Management of Alcohol Use Disorders and Comorbid Depression in Latin America) sought to test the impact of multilevel implementation strategies on rates of primary health care-based measurement of alcohol consumption and identification of depression in Colombia, Mexico, and Peru. To describe the process of development and cultural adaptation of the clinical intervention and training package. We drew on Barrero and Castro's four-stage cultural adaption model: 1) information gathering, 2) preliminary adaption, 3) preliminary adaption tests, and 4) adaption refinement. The Tailored Implementation in Chronic Diseases checklist helped us identify potential factors that could affect implementation, with local stakeholder groups established to support the tailoring process, as per the Institute for Healthcare Improvement's Going to Scale Framework. In Stage 1, international best practice guidelines for preventing heavy drinking and depression, and intelligence on the local implementation context, were synthesised to provide an outline clinical intervention and training package. In Stage 2, feedback was gathered from local stakeholders and materials refined accordingly. These materials were piloted with local trainers in Stage 3, leading to further refinements including developing additional tools to support delivery in busy primary care settings. Stage 4 comprised further adaptions in response to real-world implementation, a period that coincided with the onset of the COVID-19 pandemic, including translating the intervention and training package for online delivery, and higher priority for depression screening in the clinical pathway. Our experience highlights the importance of meaningful engagement with local communities, alongside the need for continuous tailoring and adaptation, and collaborative decision-making.

Introduction: Patients with inborn errors of immunity (IEI) have a compromised or inappropriate immune response. Although they might be considered a high-risk group for severe SARS-CoV-2 infection, the reported impact of COVID-19 in these patients has been reassuring, while the differential susceptibility of distinct types of IEI remains unclear. Objective: We aimed to describe the findings and outcomes of our known patients with IEI who were diagnosed with COVID-19. Methods: In a retrospective study from March 2020 to February 2021, four centers in Mexico collected clinical, laboratory, and genetic data from pediatric and adult patients with known diagnoses of IEI who presented with COVID-19, based on compatible symptoms and positive SARS-CoV-2 testing or known household exposure. Results: We report 31 patients with known IEI from Mexico who presented with SARS-CoV-2 infection. Seventy-four percent were male, 52% were pediatric, and 81% survived. Their ages ranged from 5 months to 56 years, with a median of 17 years. Sixty-five percent had predominant antibody deficiencies, 48% were hospitalized, and 26% required ICU. Pediatric patients had a higher hospital admission rate than adults. Inpatient mortality was 40%, and ICU mortality rate was 63%. Forty-eight percent developed pneumonia, while 36% had evidence of hyperinflammation (4 adults and 7 children). Predominant laboratory features were lymphopenia and thrombocytopenia, seen in 70 and 44% of patients, respectively. The serum D-dimer median value was 2.6 (0.5–20.6) μg/mL, and the median highest ferritin value was 1015 (32–10,303) ng/mL. Intravenous immunoglobulin was used in 80% of patients. Other treatments included macrolides (39%) and corticosteroids (29%). Six patients died from secondary infection or uncontrolled systemic inflammation. Discussion: Although impaired immunity due to IEI may be a predisposing factor for severe COVID-19, most of our patients with IEI who acquired the SARS-CoV-2 infection developed a well-tolerated infection and survived, as have more than 80% of worldwide reported patients to date. An impaired immune or inflammatory response may be a predisposing factor for some and a protective factor for others. A systematic review of the literature could help identify those patients at risk of severe disease and complications. Healthcare-associated infections should be aggressively prevented.

Introduction: Implementation of evidence-based care for heavy drinking and depression remains low in global health systems. We tested the impact of providing community support, training, and clinical packages of varied intensity on depression screening and management for heavy drinking patients in Latin American primary healthcare. Materials and methods: Quasi-experimental study involving 58 primary healthcare units in Colombia, Mexico and Peru randomized to receive: (1) usual care (control); (2) training using a brief clinical package; (3) community support plus training using a brief clinical package; (4) community support plus training using a standard clinical package. Outcomes were proportion of: (1) heavy drinking patients screened for depression; (2) screen-positive patients receiving appropriate support; (3) all consulting patients screened for depression, irrespective of drinking status. Results: 550/615 identified heavy drinkers were screened for depression (89.4%). 147/230 patients screening positive for depression received appropriate support (64%). Amongst identified heavy drinkers, adjusting for country, sex, age and provider profession, provision of community support and training had no impact on depression activity rates. Intensity of clinical package also did not affect delivery rates, with comparable performance for brief and standard versions. However, amongst all consulting patients, training providers resulted in significantly higher rates of alcohol measurement and in turn higher depression screening rates; 2.7 times higher compared to those not trained. Conclusions: Training using a brief clinical package increased depression screening rates in Latin American primary healthcare. It is not possible to determine the effectiveness of community support on depression activity rates due to the impact of COVID-19. [ABSTRACT FROM AUTHOR]

The article discusses the migration and school trajectories of young migrants in higher secondary and middle education in Mexicali, Baja California, Mexico and high school in Flagstaff, Arizona, USA. Applying semistructured interviews with narrative elements to students from both countries, we show the school discontinuities that exist between the respective educational systems. We conclude that these "transnational students" are not being addressed in their cultural diversity and pose a challenge for educational institutions. Moreover, their experiences and support networks are not leveraged by educational policies nor by the monocultural and mono-national school institutions in both contexts. [ABSTRACT FROM AUTHOR]

Between 2010 and 2019 the number of Mexican immigrants in the US declined by almost 780,000, or 7 percent. Repatriated migrants either return voluntarily to Mexico (returnees) or are forcibly removed from the US (deportees). As repatriated migrants navigate their return, access to health care in Mexico becomes a pressing need. Lack of a valid form of identification, limited awareness of services, and social stigma, among other factors, restrict health coverage in Mexico for return migrants. This study examined differences in health insurance coverage in Mexico between Mexican-born deportees and returnees from the US in a five-year period and a reference population of Mexican-born residents (nonmigrants and returnees who had been back in Mexico for five years or longer). Using data from Mexico's National Survey of Demographic Dynamics from 2014 and 2018, we found that 74.0 percent of voluntary returnees and 67.5 percent of deportees had health insurance, compared with 88.4 percent of the reference population, after adjustment for socioeconomic and demographic differences. Policy makers from federal, state, and local governments and community organizations need to improve the reintegration of repatriated migrants by reducing bureaucratic hurdles, preparing returnees and deportees for their return to Mexico, and strengthening health coverage options for return migrants.

Summary: International migration has economic and health implications. The acculturation process to the host country may be linked to childhood obesity. We use the Community Energy Balance (CEB) framework to analyze the relationship between migration and childhood obesity in Mexican households with international migrants. Using longitudinal data from the Mexican Family Life Survey (MxFLS), we examine how migrant networks affect childhood obesity in origin communities. We also review binational health programs that could be effective at tackling childhood obesity in migrant households from Mexico. Children embedded in migrant networks are at greater risk of developing overweight or obesity, suggesting a significant relationship between childhood obesity and international migration in Mexican households. Based on our search criteria, our analysis of health outreach programs shows that Ventanillas de Salud (VDS)/Health Windows has great promise to prevent childhood obesity in a culturally sensitive and trustful environment. The CEB framework is useful to understand how migration contributes to the risk of childhood overweight and obesity in migrant households. VDS is a feasible and replicable strategy with great potential to address childhood obesity among migrant families accounting for the dynamic and binational determinants of childhood obesity.

Genus Chirostoma belongs to Atherinopsidae family and it is an endemic species from the Mesa Central in Mexico. Abundance of its species have decreased and some ones have been placed on the threatened species list, because of overfishing, urbanization, industrialization, destruction, habitat fragmentation, pollution and exotic species introduction. Chirostoma jordani (Woolman, 1894) is a freshwater fish with biological, ecological, cultural, and commercial importance. It has a broad distribution in Lerma drainage, Durango and Mexico City. In this last locality, their populations, although small, still persist in Xochimilco Lake; it is necessary to implement biotechnologies for their conservation, because of these causes and their basic biology. The aim was to standardize a sperm cryopreservation protocol in C. jordani, to determine extender solution, cryoprotective agent type and concentration, equilibrium time, freezing and thawed rate to be applied in assisted reproduction and conservation of genus Chirostoma. Chirostoma jordani adult males were collected in Atlangatepec Dam, Tlaxcala State, Mexico, to fresh seminal evaluation and cryopreservation protocol standardization. Four cryoprotectants effect was evaluated: dimethylsulfoxide (DMSO), methanol (MeOH), ethylene glycol (EG), and glycerol (GL) at five concentrations: 2%, 6%, 10%, 14% and 16% v/v. Higher and lower DMSO and MeOH 10% and EG 14%, decreased post‐thaw motility percentage. Both DMSO and MeOH 10% and EG 14% had the highest post‐thaw motility percentages, 48.8 ± 1.5%, 54.5 ± 1.0% and 53.5 ± 1.0%, at 15, 10, and 5 min equilibrium times, respectively, thawed at 40°C. Chirostoma jordani sperm can be cryopreserved with both DMSO and MeOH 10%, and EG 14%. These ones can be used for assisted reproduction. GL was not efficient, since it presented a post‐thaw motility percentage very low. [ABSTRACT FROM AUTHOR]

Objective: To estimate the water erosion rate in the La Ciénega Microbasin in Malinaltepec, Guerrero, Mexico, and to evaluate control options. Design/methodology/approach: Potential erosion rate, actual erosion rate, and erosion control were estimated using the Universal Soil Loss Equation (USLE) under three conservation practices: contour plowing, successive land terracing, and live terracing with vetiver grass (Chrysopogon zizanioides (L.) Roberty). Results: High erosion potential is shown by 99.18% of the microbasin surface area. Due to vegetation, only 41% of the surface area demonstrates high or very high actual erosion, 53.6% light, and 4.6% moderate. A living barrier using vetiver is the only conservation practice, of those assessed, that effectively diminished erosion. Study limitations/implications: The lack of accurate data on rain-induced erosion was a limiting factor in this study. Findings/conclusions: The La Ciénega Microbasin has a high risk of erosion and current erosion is a problem on agricultural land. The most effective option is living barriers using vetiver.

The goal of this study was to identify predictive factors that influence return to work in burn patients treated at the National Center for Burn Care and Research at the National Institute of Rehabilitation (CENIAQ) in México City. This is a retrospective case-control study that included all burn patients of working age (16-91 years old), treated between January 2011 and December 2013. Patients were divided into two groups: unemployed (no work group) and those who returned to work (RTW). The statistical analysis was performed by a logistic regression univariate and multivariate analysis. A total of 210 subjects were included in the study. The mean age was 38 ± 15 years and 66.7% of them were male. One hundred sixty-five patients (79.6%) were able to return to work after treatment. Through univariate analysis it was found that the predictive factors for not returning to work after injury were: education lower than elementary school (OR: 3.59; CI 95%: 1.79-7.32); history of epilepsy prior to burn injury (OR: 10.18; CI 95%: 1.9-54.43); total burned surface area (TBSA) ≥20% (OR: 2.87; CI 95%: 1.46-5.64); third-degree burns (OR: 2.64; CI 95%: 1.32-5.29); hospital stay ≥20 days (OR: 2.8; CI 95%: 1.47-5.68); length of stay in the burn intensive care unit (OR: 2.5; CI 95%: 1.25-4.97); secondary infection (OR: 2.24; CI 95%: 1.15-4.38); amputations (one or more regardless of amputation level; OR: 8; CI 95%: 2.52-25.30); burn of the upper extremity (shoulder; OR: 2.21; CI 95%: 0.97-5.03); thigh (OR: 2.41; CI 95%: 1.32-5.14); and knee (OR: 2.81; CI 95%: 1.21-6.55). Some of these factors have never been reported by other authors. [ABSTRACT FROM AUTHOR]
