Substantial research has been oriented on reducing loss of life, injury, livelihoods and infrastructure disruption. In this paper, we gathered the main insights derived from the reflections of the earlier work of authors or co-authors of frameworks for understanding disaster risk.

Generation of the induced pluripotent stem cell line IOCVi001-A from a patient with the MFRP-related retinitis pigmentosa-nanophthalmos syndrome.

Retinitis pigmentosa (RP) is the most common retinal degeneration in humans and is characterized by the progressive degeneration of rods and cones and retinal pigment epithelium. We generated the IOCVi001-A induced pluripotent stem cell (iPSC) line from dermal fibroblast of a patient with a homozygous c.498_499insC (p.

Fc-gamma receptor expression and cytokine responses to intravenous human immunoglobulin in whole blood from non-pregnant and pregnant women and newborns.

Background: Intravenous immunoglobulin (IVIG) can suppress the inflammatory response in adults, but its role in pregnant women and newborns is poorly studied. While the adult immune system is considered mature, it is immature in neonates and suppressed in pregnancy. Since the immune response differs in these 3 groups, the use of IVIG could differentially modulate the immune response.

Factors influencing the technical efficiency of diabetes care at primary care level in Mexico.

Diabetes prevalence is rising globally, especially in low- and middle-income countries like Mexico, posing challenges for healthcare systems that require efficient primary care to manage the disease. However, healthcare efficiency is influenced by factors beyond decision-makers, including socioeconomic and political conditions. This study aims to evaluate the technical efficiency of primary healthcare for diabetes patients in Mexico over a 12-year period and explore the impact of contextual variables on efficiency.

Aerosol Emissions from Heated Tobacco Products: A Review Focusing on Carbonyls, Analytical Methods, and Experimental Quality.

We provide an extensive review of 17 independent and industry-funded studies targeting carbonyls in aerosol emissions of Heated Tobacco Products (HTPs), focusing on quality criteria based on the reproducibility of experiments, appropriate analytic methods, and puffing regimes. Most revised studies complied with these requirements, but some were unreproducible, while others failed to consider analytical variables that may have affected the results and/or produced unrealistic comparisons. We also provide a review of the literature on the physicochemical properties of heated tobacco and HTP aerosols, as well as the evaluation of HTPs by regulatory agencies, addressing various critiques of their relative safety profile.

Objective: To investigate the mechanical properties of gelatin hydrogels based on decaethylated chitosan and antimicrobial activity against and their biological effects with stem cells from apical papilla (SCAPs).

Using the Expanded Andersen Model to Determine Factors Associated with Mexican Adolescents' Utilization of Dental Services.

Many factors contribute as facilitators of or barriers to adolescents' use of dental services. Guided by the expanded Andersen model for dental service utilization, the aim of this study was to identify factors associated with the use of dental services among adolescents ages 12-16 in south Mexico City ( = 247). Adolescents answered a questionnaire on predisposing factors (age and gender), enabling factors (socioeconomic status, oral health support, parental years of education, and previous dental treatments), and psychosocial and behavioral factors (attitudes towards oral health; knowledge of gingivitis; alcohol, drug, and tobacco use; and depressive symptoms), and they underwent a visual clinical exam to determine their need factors (caries and gingivitis).

Agarose Gel Characterization for the Fabrication of Brain Tissue Phantoms for Infrared Multispectral Vision Systems.

Synthetic phantoms that recreate the characteristics of biological tissues are valuable tools for systematically studying and comprehending physiologies, pathologies, and biological processes related to tissues. The reproduction of mechanical and optical properties allows for the development and evaluation of novel systems and applications in areas such as imaging, optics, ultrasound, or dosimetry, among others. This paper proposes a methodology for manufacturing agarose-based phantoms that mimics the optical properties of healthy brain tissue within the wavelength infrared range of 800 to 820 nm.

Knowledge, experience, and perception of molar incisor hypomineralisation among dentists in the metropolitan area of Mexico City: a cross-sectional study.

Background: Molar-incisor hypomineralisation (MIH) is the most common developmental abnormality observed in teeth. Being a relatively new condition, its treatment can present a challenge for the dentist. There is currently no study available that has evaluated the knowledge of Mexican dental personnel.

Bridging Validity Frameworks in Assessment: Beyond Traditional Approaches in Health Professions Education.

High-stakes assessments measure several constructs, such as knowledge, competencies, and skills. In this case, validity evidence for test scores' uses and interpretations is of utmost importance, because of the consequences for everyone involved in their development and implementation. Educational assessment requires an appropriate understanding and use of validity frameworks; however, health professions educators still struggle with the conceptual challenges of validity, and frequently validity analyses have a narrow focus.

Stress, a Brief Update.

Stress is fundamental for health and adaptation; it is an evolutionarily conserved response that involves several systems in the organism. The study of the stress response could be traced back to the end of the nineteenth century with George Beard's or Claude Bernard's work and, from that moment on, several studies that have allowed the elucidation of its neurobiology and the consequences of suffering from it were consolidated. In this theoretical review, we discuss the most relevant researches to our knowledge on the study of stress response, from the concept of stress, its neurobiology, the hormonal response during stress, as well as its regulation, the effects of acute and chronic stress, stress from cognition, the different stress responses during life, as well as its relationship with different psychiatric disorders.

Forensic investigations of disasters: Past achievements and new directions.

Unlabelled: In the 2020s, understanding disaster risk requires a strong and clear recognition of values and goals that influence the use of political and economic power and social authority to guide growth and development. This configuration of values, goals, power and authority may also lead to concrete drivers of risk at any one time. Building on previous disaster risk frameworks and experiences from practice, since 2010, the 'Forensic Investigations of Disasters (FORIN)' approach has been developed to support transdisciplinary research on the transformational pathways societies may follow to recognise and address root causes and drivers of disaster risk.

Metastasis Models: Thermodynamics and Complexity.

The thermodynamic formalism of nonequilibrium systems together with the theory of complex systems and systems biology offer an appropriate theoretical framework to explain the complexity observed at the macroscopic level in physiological phenomena. In turn, they allow the establishment of an appropriate conceptual and operational framework to address the study of phenomena such as the emergence and evolution of cancer.This chapter is organized as follows: In Subheading 1, an integrated vision of these disciplines is offered for the characterization of the emergence and evolution of cancer, seen as a nonlinear dynamic system, temporally and spatially self-organized out of thermodynamic equilibrium.

Mexico: Determinants of the real exchange rate, 2001.01-2022.12.

We estimate the determinants (terms of trade, tradable to non-tradable price differentials, interest rate differentials, forward exchange rate and risk premium) of the Mexican bilateral real exchange rate (q) for the short and long run by using an Autoregressive Distributed Lag model (ARDL, Pesaran and Shin et al. (2001)) for Mexico (2001.01-2022.

Health and economic impact associated with rheumatoid arthritis discharges: a cost analysis of a two-year cohort in Mexico.

Background: Rheumatoid arthritis is a highly prevalent disease. Patients undergo various medical and pharmacological treatments, which have an economic impact on hospitals. The aim of this study was to estimate the direct economic costs of Mexican Social Security Institute (IMSS) resources used to provide healthcare to adult patients with rheumatoid arthritis in 2016-2017.

Understanding the social determinants of child mortality in Latin America over the last two decades: a machine learning approach.

The reduction of child mortality rates remains a significant global public health challenge, particularly in regions with high levels of inequality such as Latin America. We used machine learning (ML) algorithms to explore the relationship between social determinants and child under-5 mortality rates (U5MR) in Brazil, Ecuador, and Mexico over two decades. We created a municipal-level cohort from 2000 to 2019 and trained a random forest model (RF) to estimate the relative importance of social determinants in predicting U5MR.

Extracellular Vesicles Secreted by Have COX and Proteolytic Activity and Induce Hemolysis.

Several species of genus are potential pathogens and etiological agents of several diseases. The pathogenic mechanisms carried out by these amoebae in different target tissues have been documented, evidencing the relevant role of contact-dependent mechanisms. With the purpose of describing the pathogenic processes carried out by these protozoans more precisely, we considered it important to determine the emission of extracellular vesicles (EVs) as part of the contact-independent pathogenicity mechanisms of , a highly pathogenic strain.
