RESUMO

The accelerated urban sprawl of cities around the world presents major challenges for urban planning and land resource management. In this context, it is crucial to have a detailed 3D representation of buildings enriched with accurate alphanumeric information. A distinctive aspect of this proposal is its specific focus on the spatial unit corresponding to buildings. In order to propose a domain model for the 3D representation of buildings, the national standard of Ecuador and the international standard (ISO 19152:2012 LADM) were considered. The proposal includes a detailed specification of attributes, both for the general subclass of buildings and for their infrastructure. The application of the domain model proposal was crucial in a study area located in the Riobamba canton, due to the characteristics of the buildings in that area. For this purpose, a geodatabase was created in pgAdmin4 with official information, taking into account the structure of the proposed model and linking it with geospatial data for an adequate management and 3D representation of the buildings in an open-source Geographic Information System. This application improves cadastral management in the study region and has wider implications. This model is intended to serve as a benchmark for other countries facing similar challenges in cadastral management and 3D representation of buildings, promote efficient urban development and contribute to global sustainable development.

RESUMO

This study aimed to validate a semiquantitative electronic food frequency questionnaire (eFFQ) in estimating the intake of a comprehensive list of nutrients and bioactive compounds among adults from six regions of Argentina using multiple 24 h dietary recall (24HR) as a reference. A total of 163 adults completed two administrations of the eFFQ and four 24HRs. The paired t-test/Wilcoxon signed-rank test, Spearman/Pearson correlations, cross-classification, weighted kappa statistics, and Bland-Altman plots were employed to determine relative validity. To determine reproducibility, intraclass correlations (ICC), cross-classification, and weighted kappa statistics were calculated. For relative validity, crude correlations ranged from 0.15 to 0.57; energy adjustment and de-attenuation slightly improved most of these correlations. In cross-classification analysis, agreements within one quintile adjacent to exact agreement (EA ± 1) ranged from 52.2% to ~74%; extreme misclassifications were < 7%. For reproducibility, the crude ICC ranged from 0.29 to 0.85, showing moderate to good correlations for most nutrients. Cross-classification analysis showed agreement levels for the EA ± 1 quintile of 70.6% to 87.7%. Weighted kappa values ranged from 0.21 to 0.62. The results show that this eFFQ is relatively valid in ranking adults according to their nutrient intake and has an acceptable reproducibility, yet it slightly overestimates the intake of most nutrients.

RESUMO

INTRODUCTION: Extrapulmonary tuberculosis (EPTB) is a disease that can affect any organ or tissue. Due to its potential to cause more dangerous sequelae and the barriers to its timely diagnosis, greater clinical awareness of this disease is crucial. This study aimed to identify the factors associated with EPTB in the population of Oaxaca, Mexico. METHODS: This is an unpaired case-control study. The cases were patients with EPTB+ while the controls were patients with pulmonary tuberculosis (PTB+) registered in the Tuberculosis Epidemiological Surveillance System. Sociodemographic, clinical, and microbiological variables were recovered. Bivariate analyses were performed and logistic regression analyses were performed to calculate the odds ratio (OR). RESULTS: A total of 75 EPTB+ cases and 300 PTB+ controls were included. Of the total sample, 57.1% were men and 60.3% indigenous. The most frequent clinical presentations of EPTB+ were nodal (21.3%), miliary (21.3%), and breast (20.0%). According to logistic regression analysis, age <40 years (OR: 2.25 (95% CI: 1.13-4.49), female sex (OR: 1.92 (95% CI: 1.03-3.56)], urban residence (OR: 2.25 (95% CI: 1.11-4.55)), comorbidity with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (OR: 3.46 (95% CI: 1.31-9.10)), dyspnea (OR: 2.67 (1.22-5.82)), and adenopathy (OR: 3.38 (95% CI: 1.42-8.06)) were positively associated with EPTB+. CONCLUSION: These results can serve as a basis for screening EPTB+, thus improving the preventive and diagnostic capacity of local health services, taking as a starting point women under 40 years of age and patients with HIV/AIDS in urban areas, as well as the presence of adenopathy and dyspnea as clinical characteristics of the disease.

RESUMO

The COVID-19 pandemic led to a labour shortage crisis at maritime ports. Therefore, stakeholders of this industry must have robust tools to maintain good performance indicators of productivity and competitiveness. One of the most critical issues is the labour force related to allocation, performance evaluation, and foreseeing/adapting to new requirements. Many authors have studied the characteristics, elements, trends, and factors crucial in its management. However, there needs to be a comprehensive understanding of this concern. Therefore, this paper aims to develop a systematic literature review on labour force management in the maritime ports to (1) understand the elements and factors that strongly relate to human management and (2) identify future research directions to address the impact of labour shortages. Research questions and keywords were used to search academic databases for peer-reviewed papers, articles, or books. The search, selection and quality assessment processes were performed using the PRISMA methodology. This resulted in 32 documents for review and categorised based on their contributions to the research questions and content. The main findings include factors in labour force management, challenges in optimisation, technology and automation use, methods for evaluating performance, and the impact of the regulatory framework. In addition, potential future research streams were proposed to guide further studies into the needs of this industry.

RESUMO

OBJECTIVES: The use of probiotics could promote the balance of the subgingival microbiota to contribute to periodontal health. This study aimed to identify the potential of bacteria commonly associated with healthy periodontal tissues as probiotic candidates. MATERIAL AND METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the PubMed, Scopus, Science Direct, ProQuest, and Ovid databases as well as the combination of Medical Subject Headings (MeSH) and non-MeSH terms. Based on the selection criteria, original studies published in English and identifying the microorganisms present in the periodontium of healthy individuals and patients with periodontitis using the high-throughput 16S ribosomal gene sequencing technique were included. RESULTS: Out of 659 articles, 12 met the criteria for this review. These articles were published from 2012 to 2020 and mainly originated from the United States, China, and Spain. Most of these studies reported adequate criteria for selecting participants, using standardized clinical criteria, and compliance with quality based on the tools used. In periodontal healthy tissue were identified species like Actinomyces viscosus, Actinomyces naeslundii, Haemophilus parainfluenzae, Rothia dentocariosa, Streptococcus sanguinis, Streptococcus mitis, Streptococcus oralis, Streptococcus gordonii, Streptococcus intermedius, and Prevotella nigrescens which have recognized strains with a capacity to inhibit periodontopathogens. CONCLUSIONS: S. sanguinis, S. oralis, S. mitis, and S. gordonii are among the bacterial species proposed as potential probiotics because some strains can inhibit periodontopathogens and have been reported as safe for humans.

RESUMO

Una de las mayores complejidades que se presentan respecto de la responsabilidad civil por daños causados por sistemas de inteligencia artificial viene dada por la dificultad de atribuir la conducta que causa daño a un sujeto particular. Frente a ello, este artículo expone la importancia del principio ético de la intervención humana para la responsabilidad civil, cuya función consiste en constituir la guía para la interpretación y aplicación de sus reglas en los casos en los que, como resultado de una acción u omisión emanada de una decisión, recomendación o predicción realizada por un sistema de inteligencia artificial, se causen daños a las personas.

One of the main challenges associated with regard to civil liability for damages resulting from artificial intelligence systems is the difficulty of attributing the behavior that led to harm to a specific individual. The aim of this article is to highlight the significance of the ethical principle of human intervention for civil liability. This principle serves as a guide for interpreting and applying rules when artificial intelligence systems cause harm to individuals due to actions, decisions, recommendations or predictions.

RESUMO

An experiment was carried out to evaluate the effect of spring and autumn seasons on the reproductive activity of Merino Socorro Island ewes and their crosses with Pelibuey under heat stress (HS) conditions in the tropics. All ewes (n = 80) were randomly assigned to one of two breeds during the first and second periods, respectively: (1) Twenty Socorro Island Merino ewes (SIM) and (2) 20 Pelibuey Crossbred ewes (PBC). Animals were fed the same diet and given water ad libitum. All statistical analyses were performed using SAS statistical software 9.12 procedures. In both seasons, a mean of more than 80 U of maximum THI was obtained, while in spring and autumn, the minimum THI exceeded 30 and 40 U, respectively. All animals were in oestrus and ovulated in both seasons. The frequency of animals in spring during the first 48 h of oestrus expression was greater (p < 0.05) than 48-55 h but similar (p > 0.05) than 55-65 h; in autumn during the first 48 h and 48-55 h were similar (p > 0.05), but different (p < 0.05) than 55-65 h. The duration of oestrus expression was longer in the spring than in the autumn (p < 0.05). The frequency of animals was higher (p < 0.05) in SIM than in PBC ewes during the first oestrus cycle (1-17 d) and was also higher (p < 0.05) in PBC than in SIM ewes during the second oestrus cycle (18-35 d). The SIM ewes produced more (p < 0.05) progesterone (P4) than the PBC ewes. During the sampling days of the oestrus cycle, more P4 was created in autumn than in spring (p < 0.05). Both breeds showed severe HS. In the future, ewes treated under assisted reproductive programs in the tropics may improve reproductive efficiency.

RESUMO

Introduction: Acute appendicitis secondary to parasitic infections is uncommon, being detected in less than 1% of cases. Balantidium coli is a parasite found in pigs and primates with zoonotic potential. To date, only three cases of acute appendicitis induced by this parasite have been documented globally. Case: A 7-year-old female patient, who consumed pork daily, presented to the emergency department with a one-day history of abdominal pain in the lower quadrants, described as colic-like, alongside abdominal distension. Initial abdominal radiography led to a diagnosis of intestinal obstruction. Conservative management without therapeutic response necessitated referral to a higher complexity center. Upon admission, an abdominal computed tomography scan diagnosed acute appendicitis and secondary ileus. During surgical intervention, an appendiceal phlegmon formed by loops of the small intestine was mechanically released, revealing a perforated appendix with extensive fecal peritoneal contamination. Pathological analysis identified an inflammatory infiltrate and the presence of Balantidium coli trophozoites. Medical treatment included Piperacillin-Tazobactam and Metronidazole. The patient was discharged after 10 days of medical treatment. Discussion: Acute appendicitis caused by Balantidium coli is a rare occurrence. It is crucial to identify parasites in pathological samples due to their impact on postoperative management. The close contact between humans and pigs, especially in developing countries, suggests that the prevalence of parasitic infection and colonization by Balantidium coli may be higher than currently recognized. Regarding the identification of this patient's specific exposure, the regular consumption of pork suggests the hypothesis that improper processing is linked to the acquisition of the parasitic infection.

RESUMO

Introduction: The COVID-19 disease has been one of the most harmful pandemics for humanity; therefore, ensuring adherence to preventive and control measures is essential. This adherence largely depends on the population's knowledge, attitudes, and practices (KAP) towards COVID-19. Objective: To identify the level of knowledge, attitudes, and practices towards COVID-19 prevention and its associated factors in Oaxaca, Mexico. Materials and Methods: This cross-sectional and analytical study surveyed adults online regarding KAP. Descriptive statistics and Chi-square or Fisher's exact tests were used for categorical comparisons. Factors associated with higher KAP levels were analyzed by calculating odd ratios (ORs) through logistic regression. Results: A total of 176 people participated, of whom 82.42% were women, and 81.83% were <30 years old. Among the participants, 90.88% identified direct contact with infected individuals as the main mode of transmission, 73.86% correctly identified the incubation period, and 93.22% referred to handwashing as the main preventive measure. The KAP scores were 65.34%, 32.95%, and 40.91%, respectively, with no differences by sex or age. Discussion: Participants with higher COVID-19 knowledge and more positive attitudes towards the pandemic were associated with more frequent preventive practices [OR:1.89 (CI:1.17-3.73)] and [OR:3.21 (CI:1 .62-6.35)], respectively, compared to those with lower scores. Conclusions: The study population has a low level of KAP; greater knowledge about COVID-19 and more positive attitudes towards the pandemic increase preventive practices.

RESUMO

The receptor for advanced glycation end products (RAGE) and its gene (AGER) have been related to lung injury and inflammatory diseases, including chronic obstructive pulmonary disease (COPD). We aimed to evaluate the association of rs2071288, rs3134940, rs184003, and rs2070600 AGER single-nucleotide variants and the soluble-RAGE plasma and sputum levels with COPD secondary to biomass-burning smoke (BBS) and tobacco smoking. Four groups, including 2189 subjects, were analyzed: COPD secondary to BBS exposure (COPD-BBS, n = 342), BBS-exposed subjects without COPD (BBES, n = 774), tobacco smoking-induced COPD (COPD-TS, n = 434), and smokers without COPD (SWOC, n = 639). Allelic discrimination assays determined the AGER variants. The sRAGE was quantified in plasma (n = 240) and induced-sputum (n = 72) samples from a subgroup of patients using the ELISA technique. In addition, a meta-analysis was performed for the association of rs2070600 with COPD susceptibility. None of the studied genetic variants were found to be associated with COPD-BBS or COPD-TS. A marginal association was observed for the rs3134940 with COPD-BBS (p = 0.066). The results from the meta-analysis, including six case-control studies (n = 4149 subjects), showed a lack of association of rs2070600 with COPD susceptibility (p = 0.681), probably due to interethnic differences. The sRAGE plasma levels were lower in COPD-BBS compared to BBS and in COPD-TS compared to SWOC. The sRAGE levels were also lower in sputum samples from COPD-BBS than BBES. Subjects with rs3134940-TC genotypes exhibit lower sRAGE plasma levels than TT subjects, mainly from the COPD-BBS and SWOC groups. The AGER variants were not associated with COPD-BBS nor COPD-TS, but the sRAGE plasma and sputum levels are related to both COPD-BBS and COPD-TS and are influenced by the rs3134940 variant.

RESUMO

Introducción. El tamaño al nacer se encuentra sujeto a influencias genéticas y ambientales; la altura geográfica es muy influyente. El peso al nacer (PN) es el indicador más utilizado para evaluarlo; existen diferentes estándares y referencias. Debido a la variabilidad de la distribución del PN en relación con la altura en la provincia de Jujuy (Argentina), este trabajo analiza la distribución percentilar del PN para tierras altas (TA) y tierras bajas (TB) jujeñas según edad gestacional (EG) y sexo, y su comparación con una referencia nacional y el estándar internacional INTERGROWTH-21st (IG-21). Población y métodos. Se analizaron los registros de 78 524 nacidos vivos en Jujuy en el período 20092014. Utilizando el método LMS, se estimaron los percentiles 3, 10, 50, 90 y 97 de PN/EG por sexo, para TA (≥2000 msnm), TB (<2000 msnm) y el total provincial, y se compararon gráficamente con la referencia poblacional argentina de Urquía y el estándar IG-21. La significación estadística se determinó mediante la prueba de Wilcoxon. Resultados. El PN en Jujuy presentó distribución heterogénea, con diferencias estadísticamente significativas (p <0,05) entre TB y TA. Al comparar con la referencia nacional y el estándar IG-21, se observaron diferencias por altitud, principalmente en los percentiles 90 y 97 para ambas regiones, y en los percentiles 3 y 10 en TA comparados con el estándar. Conclusiones. Se observó variabilidad de la distribución del PN asociada a la altura geográfica, por lo que, para evaluar el crecimiento intrauterino, resulta fundamental incluir la EG y el contexto donde transcurre la gestación.

Introduction. Size at birth is subject to genetic and environmental influences; altitude is highly influential. Birth weight (BW) is the most widely used indicator to assess size at birth; different standards and references are available. Due to the variability in BW distribution in relation to altitude in the province of Jujuy (Argentina), the purpose of this study is to analyze the percentile distribution of BW in the highlands (HL) and the lowlands (LL) of Jujuy based on gestational age (GA) and sex and compare it with a national reference and the INTERGROWTH-21 st (IG-21) international standard. Population and methods. The records of 78 524 live births in Jujuy in the 2009­2014 period were analyzed. Using the LMS method, the 3 rd, 10 th, 50 th, 90 th, and 97 th percentiles of BW/GA by sex were estimated for the HL (≥ 2000 MASL), the LL (< 2000 MASL), and the total for Jujuy, and compared with the Argentine population reference by Urquía and the IG-21 standard using growth charts. The statistical significance was established using the Wilcoxon test. Results. BW in Jujuy showed a heterogeneous distribution, with statistically significant differences (p < 0.05) between the LL and the HL. When compared with the national reference and the IG-21 standard, differences in terms of altitude were observed, mainly in the 90 th and 97 th percentiles for both regions and the 3 rd and 10 th percentiles in the HL compared with the international standard. Conclusions. BW distribution varied in association with altitude; therefore, to assess intrauterine growth, it is critical to include GA and the environment in which the pregnancy takes place.

RESUMO

SUMMARY: Partial or total dental loss (edentulism) is associated with decreased quality of life. Chile has large socioeconomic gaps, which are also recognized in oral health, but it is not known how Edentulism has evolved throughout the country. The aim of this study was to determine the edentulism in people born during the 19th and 20th centuries in Chile, who died in the 20th century, and to compare it with current data from the Chilean Ministry of Health (MINSAL) to observe its evolution in the country. For this purpose, 60 3D models of skulls from the Subactual Osteological Collection of Santiago were analyzed (30 individuals per sex), in which the presence and absence of teeth in antemortem in the maxilla were analyzed. A high percentage of tooth loss was observed, with 65 % partial edentulism, a 30 % total edentulism, and only 5 % had complete dentition in this osteological collection. In addition, a significant decrease over time was found; in 2017, the percentage of complete dentition at the national level was 32.8 %. A higher frequency of edentulism was also found in females from the osteological collection, with a significant probability of twice as much edentulism as in males. However, this sex difference was smaller than those found in the current study. Our study is the first to compare edentulism in Chile in two different time periods, since, in addition to studying it in the 19th and 20th century, it is carried out with data from the present day and in line with previous research, reveals the importance of socioeconomic and sex variables for dental loss.

La pérdida parcial o total de dientes (edentulismo) se asocia a una disminución de la calidad de vida. Chile tiene grandes brechas socioeconómicas, que también se reconocen en la salud oral, pero se desconoce cómo ha evolucionado el edentulismo en el país. El objetivo de este estudio fue determinar el edentulismo en personas nacidas durante los siglos XIX y XX en Chile y fallecidas en el siglo XX, y compararlo con datos actuales del Ministerio de Salud de Chile (MINSAL) para observar su evolución en el país. Para ello, se analizaron 60 modelos 3D de cráneos de la Colección Osteológica Subactual de Santiago (30 individuos por sexo), en los que se analizó la presencia y ausencia de dientes en dentición antemortem en el maxilar. Se observó un alto porcentaje de pérdida dentaria, con un 65 % de edentulismo parcial y un 30 % de edentulismo total, y sólo un 5 % presentaba dentición completa en esta colección osteológica. Además, se encontró una disminución significativa a lo largo del tiempo; en 2017, la dentición completa a nivel país fue del 32,8 %. También se encontró una mayor frecuencia de edentulismo en las mujeres de la colección osteológica, con una probabilidad significativa del doble de edentulismo que en los hombres. Sin embargo, esta diferencia de sexo fue menor que la hallada en datos actuales. Este estudio es el primero que compara el edentulismo en Chile en dos épocas diferentes, ya que además de estudiarlo en los siglos XIX y XX, se realizó con datos de la actualidad y, en línea con investigaciones previas, revela la importancia de las variables socioeconómicas y de sexo en la pérdida dental.

RESUMO

Lead is a very toxic metal which affects human health. An alternative to remove it from contaminated water is the use of macrophytes, as Scirpus americanus Pers. This species is tolerant to salt and metals and has high biomass. The present research analyzed the capacity of hydroponic cultures of normal and transgenic plants (line T12) from S. americanus to remove high concentrations of lead. The antioxidant response of plants to metal exposure was also measured. The MINTEQ3.1 program was used to define the media composition in order to have the metal available to the plants. According to MINTEQ3.1 predictions, sulfate, phosphate, and molybdenum must be removed from the medium to avoid lead precipitation. Therefore, the plants were maintained in a modified Hoagland solution containing 100, 250, and 400 mg/L lead. The presence of metal did not affect the growth of roots and stems at all concentration tested. The normal and T12 plants accumulated 69,389 mg/kg and 45,297 mg/kg lead, respectively, and could be considered hyperaccumulators. Plant tolerance to lead mainly involved an increase in superoxide dismutase activity and glutathione accumulation. The bioconcentration factor indicated that S. americanus plants bioconcentrated between 192 and 300 times the metal; thus, S. americanus could be used for phytoremediation of water contaminated with a high concentration of lead.

RESUMO

The aim of the present study was to assess the impacts of roasting and the type of extraction solvent (ethanol or water) on the hypolipidemic act ivity of xoconostle fruit peel extracts in a tyloxapol - induced model of hyperlipidemia. Water and ethanol extracts from raw and roasted Opuntia joconostle peels were obtained to quantify the phytochemicals contained within and assess their hypolipidemic ac tivity in rats (n=5) against tyloxapol - induced dyslipidemia (400 mg/kg). The raw ethanol and water extracts, as well as the roasted water extract (200 mg/kg), showed hypolipidemic activity in the tyloxapol - treated group ( p <0.05). In contrast, the roasted s ample extracted with ethanol did not show this effect. The concentrations of phenolic compounds (39.80 mg GAE/g) and flavonoids (16.42 ± 0.14 mg QE/g) were higher in the ethanolic extracts than in the aqueous extracts. Conversely, the concentration of beta lains (115.51 ± 1.66 mg/100 g) was higher in the water extracts than in the ethanol extracts. It was concluded that the roasting process modified the concentration of some phytochemicals and their antioxidant capacity in vitro , producing a hypolipidemic ef fect in tyloxapol - induced hyperlipidemic rats

El objetivo del presente estudio fue evaluar el impacto del tostado y del tipo de disolvente de e xtracción (etanol o agua) sobre la actividad hipolipidémica de los extractos de cáscara de frutos de xoconostle en un modelo de hiperlipidemia inducido por el tyloxapol. Se obtuvieron extractos acuosos y etanólicos de cáscara cruda y asada de Opuntia jocon ostle para cuantificar los fitoquímicos que contienen y evaluar su actividad hipolipidémica en ratas (n=5) contra la dislipidemia inducida por el tyloxapol (400 mg/kg). Los extractos acuosos y etanólicos crudos, así como el extracto acuoso tostado (200 mg/ kg), mostraron actividad hipolipidémica en el grupo tratado con tiloxapol ( p <0,05). En cambio, la muestra asada y extraída con etanol no mostró este efecto. Las concentraciones de compuestos fenólicos (39,80 mg GAE/g) y flavonoides (16,42 ± 0,14 mg QE/g) f ueron mayores en los extractos etanólicos que en los acuosos. Por el contrario, la concentración de betalaínas (115,51 ± 1,66 mg/100 g) fue mayor en los extractos acuosos que en los etanólicos. Se concluyó que el proceso de asado modificó la concentración de algunos fitoquímicos y su capacidad antioxidante in vitro , produciendo un efecto hipolipidémico en ratas hiperlipidémicas inducidas por el tyloxapol.

RESUMO

Peanuts (Arachis hypogaea L.) are among the most important leguminous crops in Argentina. During the growing season, they are frequently attacked by fungal diseases, including Thecaphora frezii. The spores of T. frezii are structures that confer resistance to this phytopathogen. The transition from teliospore to hypha is a characteristic process of some fungi, which is essential for completing their life cycle. Using the transcriptomes of teliospores and hyphae of T. frezii, we aimed to identify genes that were differentially expressed during this transition, and we found 134 up-regulated and 66 down-regulated genes, which would participate in different cellular processes such as: (a) cell cycle and DNA processing; (b) cell fate; (c) rescue, defense and cellular virulence; (d) detoxification by CYP450; (e) energy; (f) nutrient interaction and nutritional adaptation; (g) metabolism; (g) proteins with binding functions or cofactor requirements; (h) stress, cell differentiation and biogenesis of cell components; and (i) transport, cell communication and transcription. The identification of genes in T. frezii and their expression levels during different stages of differentiation could contribute to our understanding of the biological mechanisms in this fungus.

RESUMO

SUMMARY: The new paradigm in Forensic Sciences initiated by the entry of genetics (the current standard of legal evidence) and accentuated by recognized wrongful convictions derived from experts today in the eye of criticism, has highlighted the potential for bias and error in forensic disciplines when they depend on human interpretation and subjectivity, which has not been avoided by Forensic Odontology (FO). However, a subjective judgment is not necessarily wrong, so the refinement of processes, the development of standards, and robust research can contribute to the validity of interpretation to increase objectivity. Latin America (LATAM) has its own realities and needs, which have conditioned the priorities and objectives of FO research. A scoping review is presented to systematically map the investigation of LATAM researchers and identify the objective or subjective nature of their assessments. LATAM shows interesting productivity and intentions to adhere to international standards, with Brazil leading this research significantly, followed by Chile and Colombia, among others. However, there is a disproportionate approach in certain lines of research (dental age estimation), and needs to address other quantitative studies, and to improve the visibility of the LATAM FO research.

El nuevo paradigma en ciencias forenses iniciado por la entrada de la genética (el actual estándar de la evidencia jurídica), y acentuado por reconocidas condenas injustas derivadas de pericias hoy en el ojo de la crítica, ha destacado el potencial de sesgo y error que poseen algunas disciplinas forenses cuando dependen de la interpretación humana y la subjetividad, lo cual no ha sido ajeno a la odontología forense (OF). Sin embargo, un juicio subjetivo no necesariamente es erróneo, con lo que el refinamiento de procesos, el desarrollo de estándares y la investigación robusta pueden contribuir a validar esa interpretación para aumentar su objetividad. Latinoamérica (LATAM) posee realidades y necesidades propias que han condicionado las prioridades y objetivos de la investigación en OF. Se presenta una revisión con búsqueda sistemática para mapear sistemáticamente la investigación en OF realizada por investigadores latinoamericanos, así como identificar la naturaleza objetiva o subjetiva de sus evaluaciones. LATAM demuestra una productividad interesante e intenciones de adherirse a estándares internacionales, con Brasil liderando significativamente esta investigación, seguido por Chile y Colombia entre otros. Sin embargo, se observa un enfoque desproporcionado en ciertas líneas de investigación (estimación de edad dental particularmente), y necesidad tanto de abordar otros estudios cuantitativos como de mejorar la visibilidad de la investigación latinoamericana en OF.

RESUMO

BACKGROUND: Knowledge, attitudes, and practices related to oral health among parents play a crucial role in shaping oral hygiene and preventing early childhood caries. This study was intended to determine the effect of a neuroeducational strategy in improving knowledge, attitudes, and practices related to early childhood caries among mothers or caregivers of children. METHODS: A quasi-experimental study was conducted, implementing an educational strategy involving 33 mothers or female caregivers of children who met specific selection criteria. The strategy consisted of three key elements derived from neuroeducation: (1) experiment, (2) surprise and play, and (3) learn. Based on the participants' attendance at the sessions, they were categorized into two groups: those who underwent in-person intervention (G1) and those who received a combined in-person and virtual intervention (G2). The impact of the strategy was evaluated by comparing the participants' knowledge and attitudes, as well as their children's plaque index, before and after the intervention (immediate and 6-month impact). RESULTS: The participants exhibited a favorable and statistically significant effect on the median number of correct answers related to knowledge (G1 immediate effect (IE): p = 0.03, 6-month effect (ME): p = 0.002; G2 IE p = 0.002, ME: p = 0.001), and in the children's plaque index (G1 IE: p = 0.003, ME: p = 0.003; G2 IE: p = 0.033, ME: p = 0.003). Furthermore, there was an increase in the number of participants with a high level of knowledge (G1 IE: 41.5%; ME: 75%; G2 IE: 45.5%, ME: 42.9%), and of children with a good level of oral hygiene (G1 IE: 50%; ME: 73.0%; G2 IE: 27.3%, ME: 84.6%). Finally, qualitative interviews revealed a lasting clarity in concepts and sustained knowledge and attitudes at the six-month mark. However, a slightly diminished understanding of the relationship between bacteria, sugar, and caries was observed in G2 group, and some loss of association in the G1 group, at six months. CONCLUSION: The implementation of this strategy resulted in significant and lasting impacts on knowledge, attitudes, and practices, especially in the G1 group. Nevertheless, there is a need for further reinforcement of the association between bacteria, sugar, and caries.
