Factores de riesgo transdiagnósticos de los trastornos emocionales en adultos: una revisión sistemática / Transdiagnostic risk factors of emotional disorders in adults: A systematic review

La comorbilidad es más la regla que la excepción en salud mental y, sobre todo, en el caso de la ansiedad y la depresión. Los modelos transdiagnósticos estudian los procesos subyacentes para mejorar el tratamiento y la comprensión de la salud mental. Objetivo: Esta revisión sistemática busca evidencias sobre los factores de riesgo transdiagnósticos para la ansiedad y la depresión en la población clínica diagnosticada de estas condiciones psicopatológicas, analizando los diferentes tipos o categorías de factores identificados. Método: Se registró una revisión sistemática en PROSPERO (número de registro CRD42022370327) y se diseñó de acuerdo con las guías PRISMA-P. La calidad del estudio fue evaluada por dos revisores independientes con conocimiento del campo para reducir el posible sesgo. Resultados: Cincuenta y tres artículos fueron examinados y las variables transdiagnósticas fueron agrupadas en tres categorías: psicológicas, biológicas y socioculturales. Conclusiones: La categoría más estudiada fue la de variables psicológicas, en especial los procesos cognitivos, afecto negativo y neuroticismo, intolerancia a la incertidumbre, sensibilidad a la ansiedad. Los factores biológicos y socioculturales requieren más estudio para sustentar su enfoque transdiagnóstico.(AU)

Biological and sociocultural factors require more study to support their transdiagnos-tic approach.(AU)

Impact of mediterranean diet promotion on environmental sustainability: a longitudinal analysis.

OBJECTIVE: This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). METHODS: Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models. RESULTS: After one year of intervention, the kcal/day consumed was significantly reduced (-125,1 kcal/day), adherence to a MD pattern was improved (+0,9) and the environmental impact due to the diet was significantly reduced (GHG: -361 g/CO2-eq; Acidification:-11,5 g SO2-eq; Eutrophication:-4,7 g PO4-eq; Energy use:-842,7 kJ; and Land use:-2,2 m2). Higher adherence to MD (high vs. low) was significantly associated with lower environmental impact both at baseline and one year follow-up. Meat products had the greatest environmental impact in all the factors analysed, both at baseline and at one-year follow-up, in spite of the reduction observed in their consumption. CONCLUSIONS: A program promoting a MD, after one year of intervention, significantly reduced the environmental impact in all the factors analysed. Meat products had the greatest environmental impact in all the dimensions analysed.

Preservation of the inferior alveolar vasculonervous bundle in mandibular resective therapies: systematic review and report of two cases.

BACKGROUND: Segmental surgical resection is a frequently indicated procedure to treat aggressive mandibular tumors. One of the most important complications derived from this technique is permanent paresthesia of the inferior alveolar nerve (IAN), which significantly affects the quality of life of patients who experience it. This could be avoided through maneuvers that preserve the IAN. The objective of this paper is to review the main techniques for IAN preservation and to present 2 cases with the technique used by the author. MATERIAL AND METHODS: A systematic review was performed according to the PRISMA guidelines, apropos of two clinical cases reported in this study. The MEDLINE/PubMed and Scopus databases were searched. Several variables were considered and are presented in detail in the form of tables and figures. In addition, 2 case reports with NAI preservation techniques are presented. RESULTS: 13 articles were finally obtained for analysis. 127 patients were evaluated, reporting mandibular resections associated with various pathologies. Various surgical techniques were used, all with the same goal of maintaining the IAN. In most of the patients, the maintenance of sensitivity was achieved, which was verified with different methods. CONCLUSIONS: Preservation of the IAN in maxillofacial surgical procedures where surgical resection of the mandibular bone has been performed is an alternative that has demonstrated successful results in terms of reducing postoperative sequelae and is currently positioned as a necessary and feasible procedure.

Phylogenetic analysis of the partial sequences of the env and tax BLV genes reveals the presence of genotypes 1 and 3 in dairy herds of Antioquia, Colombia.

Bovine leukemia virus (BLV) is a retrovirus that primarily infects dairy cows. Although few studies have also used the tax gene, phylogenetic studies of BLV use mostly the env gene. The aim of this work was to establish the circulating genotypes of BLV in specialized dairy cattle from Antioquia, Colombia. Twenty blood samples from Holstein Friesian cows were collected, and their DNA was isolated. A PCR was performed for a partial region of the env and tax genes. A phylogenetic analysis was carried out using the maximum likelihood and Bayesian methods for both genes. Nineteen sequences were identified as genotype 1 by env and tax genes. Only one sequence was clustered with genotype 3 and had the highest proportion of different nucleotide sites compared to other strains. Four amino acid substitutions in the 134 amino acid residue fragment of the Env protein were identified in the Colombian sequences, and three new amino acid substitutions were reported in the 296 amino acid residue fragment of the Tax protein. R43K (Z finger), A185T (Activation domain), and L105F changes were identified in the genotype 3 sample. This genotype has been reported in the United States, Japan, Korea, and Mexico, but so far, not in Colombia. The country has a high rate of imported live animals, semen, and embryos, especially from the United States. Although it is necessary to evaluate samples from other regions of the country, the current results indicate the presence of two BLV genotypes in specialized dairy herds.

Characterization of an energy efficient pulsed current TIG welding process on AISI 316 and 304 stainless steels.

This paper presents the characterization of a TIG welding process carried out by means of an arc welding power supply able to provide dc or pulsed current. The arc welding power supply is based on resonant power converters and an FPGA-based control circuit. Dc and multiple pulsed operations up to 1 kHz with different pulse widths have been tested. The operation of the proposed welding power supply has been compared to that of a high-quality commercial welding machine. Regarding performance, the investigated electrical parameters are: power factor, power conversion efficiency and the energy consumption of the process. The radiography and mechanical properties of the welds have been examined. The mechanical properties of the welded joints characterized through tensile tests are the yield stress, tensile strength and the strain under maximum stress. In addition, the impact properties of the joints were determined through Charpy tests and the curves relating energy absorbed and temperature were obtained. The results show an improved performance of the proposed arc welding power supply over the commercial counterpart, with higher efficiency and power factor, as well as lower energy consumption. The yield stress and tensile strength results indicate that the welded plates using pulsed modes with the proposed power supply are comparable to the reference weld performed with dc operation using the commercial welder. Remarkably, it was observed that the ductility of the welded plates using pulsed modes with the proposed power supply outperforms those of the reference weld carried out with dc arc using the commercial welder.

Introduction: DASH questionnaire was designed to assess upper limb function in musculoskeletal pathologies. The aim of this manuscript is to study the reliability and validity of this questionnaire, to determine if is adequate to use in women with lymphedema due to breast cancer treatment. Methods: Prospective study in 65 women with lymphedema due to breast cancer treatment was done, in which the reliability of DASH score with internal consistency (Cronbach's alpha) and test–retest reproducibility 15 days’ interval (interclass correlation coefficient) and validity by correlation with SF-36v2 and FACT-B+4 (r or Kendall's τ b) scores was investigated. Results: The internal consistency and the test–retest were Cronbach's alpha 0.969 and interclass correlation coefficient 0.861, respectively. There was correlation between the DASH score with the SF-36v2 score, mainly in the areas of physical function, body pain and physical role (r 0.800, 0.738, and 0.682, respectively; p<0.001), and lowest with the emotional and social wellbeing. The DASH score had correlation with FACT-B+4 (0.836; p<0.001) and the subscales the upper limb score (r=0.816; p<0.001), and there was no correlation with the social/familiar subscale (r=0.193; p=0.216). Conclusion: The DASH questionnaire is a reliable and valid tool to assess upper limb functionality in Spanish women with breast cancer related lymphedema.(AU)

Population well-being and the COVID-19 vaccination program in Chile: evidence from Google Trends.

OBJECTIVE: We analyze the dynamics of the mental well-being of the Chilean population in response to the progress of the vaccination strategy implemented by the government. STUDY DESIGN: This study aims at investigating the possibility of using Google Trends as an instrument for tracking mental well-being of the Chilean population. METHODS: We use the volume of searches for keywords in Google Trends (GT) related to Anguish, Anxiety, Depression, and Stress as a proxy for population well-being. Using event study methods, we analyze social attention reactions to news about the vaccination program. We implement a Difference-in-Difference-in-Differences estimation to estimate changes in population welfare by socio-economic status induced by the progress of inoculation. RESULTS: We show that social attention to mental health problems is sensitive to news about the vaccination program. Moreover, and most importantly, we find that mental well-being responds positively to the percentage of inoculated people. This phenomenon appear to be permanent and affected by socio-economic status, with the wealthier population experiencing greater improvements than the less wealthy. CONCLUSIONS: During the COVID-19 vaccination program in Chile, social attention to mental health problems appears to be sensitive to news about the vaccination program. There is also strong evidence of socio-economic status-induced heterogeneity in population responses to program implementation. The above phenomena appears to be permanent and cannot be attributed to either socio-economic segregation in access to vaccines or to the highly stratified schedule of the vaccination program.

Cirrosis hepática alcohólica: actualización epidemiológica de la tasa de mortalidad entre los años 2017-2021 en Chile / Alcoholic liver cirrhosis: epidemiological update of mortality rates between 2017-2021 in Chile

Introducción: La cirrosis hepática alcohólica (CHA) es una etapa final de la enfermedad hepática por alcohol. Dada la falta de análisis epidemiológicos recientes en Chile, el objetivo de este estudio es comparar descriptivamente la tasa de mortalidad (TM) por CHA entre los años 2017-2021 en Chile. Metodología: Estudio observacional y transversal, sobre defunciones por CHA en Chile durante 2017-2021 según sexo y edad (n=2.551). Datos obtenidos del Departamento de Estadística e Información en Salud. Se utilizó estadística descriptiva y cálculo de TM. No requirió aprobación del comité de ética. Resultados: Se obtuvo una TM para el período estudiado de 3,98/100.000 habitantes. El sexo masculino presenta la mayor TM con 7,05. El grupo etario de 65-79 años presenta la mayor TM con 9,08/100.000 habitantes. Para TM por región, lidera Los Lagos con 39,84/100.000 habitantes, la menor es Coquimbo con 10,03/100.000 habitantes. Discusión: La mayor TM por CHA se encuentra en hombres, lo cual puede deberse a un mayor consumo social. El grupo etario de 65-79 años presentó la mayor TM, coincidiendo con estadísticas internacionales. El porcentaje de ruralidad pudiera afectar el consumo de alcohol, aumentando la TM por CHA en aquellas más rurales. La prevención es vital para evitar el desarrollo de CHA, siendo crucial establecer programas de salud pública para evitar el consumo de alcohol en Chile. Se identificó una falta de datos epidemiológicos en Chile, por lo que se invita a la actualización de estos.

Introduction: Alcoholic liver cirrhosis (ALC) is one of the final stages of alcoholic-related liver disease (ARLD). Due to the lack of recent epidemiological research in Chile, the main objective of this study is to descriptively compare the mortality rate (MR) due to ALC between the years 2017-2021 in Chile. Methodology: Observational and cross-sectional study, on the number of deaths owing to ALC in Chile during 20172021 according to sex and age (n=2,551). Data obtained from the department of statistics and health information. Descriptive statistics and MR calculation were used. Ethics committee approval was not required. Results: A MR was obtained for the studied period of 3.98/100,000 inhabitants. The male sex submitted the highest MR with 7.05. The age group of 65-79 years presents the highest MR with 9,08/100,000 inhabitants. The region with the highest MR is Los Lagos with 39,84/100.000 inhabitants and the one with the lowest is Coquimbo with 10,03/100.000 inhabitants. Discussion: The highest MR is found in men, which may be due the fact that, socially, men consume more alcohol than women. The age group of 65-79 years presented the highest MR, which coincides with the international statistics. The percentage of rurality impacts the alcohol consumption increasing the MR due to ALD in the most rural areas. Prevention is vital to avoid its development, so it's crucial to establish public health programs to avoid alcohol consumption in Chile. A lack of updated epidemiological information has been identified in our country, therefore it is invited to update the epidemiological data.

Capacitors Based on Polypyrrole Nanowire Electrodeposits.

The electrochemical polymerization of polypyrrole nanowires is carried out using potentiodynamic and galvanostatic methods in order to enhance the performance of the modified electrodes as capacitor devices. The electrochemical, spectroscopic, and morphological properties are determined through cyclic voltammetry, Raman spectroscopy and scanning electron microscopy, respectively, corroborating the presence of PPy-nw in dimensions of 30 nm in diameter. Characterization as a capacitor revealed that the nanowire structure enhances key parameters such as specific capacitance with 60 times greater value than bulk polymer modification, in addition to a significant increase in stability. In this way, it is verified that electrodes modified with polypyrrole nanowires obtained in situ by electrochemical methods constitute an excellent candidate for the development of capacitors.

From animal studies into clinical trials: the relevance of animal models to develop vaccines and therapies to reduce disease severity and prevent hRSV infection.

INTRODUCTION: Human respiratory syncytial virus (hRSV) is an important cause of lower respiratory tract infections in the pediatric and the geriatric population worldwide. There is a substantial economic burden resulting from hRSV disease during winter. Although no vaccines have been approved for human use, prophylactic therapies are available for high-risk populations. Choosing the proper animal models to evaluate different vaccine prototypes or pharmacological treatments is essential for developing efficient therapies against hRSV. AREAS COVERED: This article describes the relevance of using different animal models to evaluate the effect of antiviral drugs, pharmacological molecules, vaccine prototypes, and antibodies in the protection against hRSV. The animal models covered are rodents, mustelids, bovines, and nonhuman primates. Animals included were chosen based on the available literature and their role in the development of the drugs discussed in this manuscript. EXPERT OPINION: Choosing the correct animal model is critical for exploring and testing treatments that could decrease the impact of hRSV in high-risk populations. Mice will continue to be the most used preclinical model to evaluate this. However, researchers must also explore the use of other models such as nonhuman primates, as they are more similar to humans, prior to escalating into clinical trials.

Fetal hemoglobin regulating genetic variants identified in homozygous (HbSS) and heterozygous (HbSA) subjects from South Mexico.

Hemoglobin S is caused by a nucleotide change in HBB gene (HBB:c.20A>T, p.Glu6Val), is presented in diverse forms: simple carriers (HbSA), homozygotes (HbSS) also known as sickle cell anemia, and compound heterozygotes with other ß-hemoglobinopathies. It is worldwide distributed, in Mexico, is frequently observed in the southern states Guerrero, Oaxaca and Chiapas. Elevated fetal hemoglobin (HbF) is associated with mild phenotype; single-nucleotide variants (SNVs) in modifier genes, such as BCL11A, HBG2, HBBP1 pseudogene and HBS1L-MYB intergenic region, upregulate HbF synthesis. The aim of this study was to identify HbF regulating genetic variants in HbSS and HbSA Mexican subjects. We studied 39 individuals (HbSS = 24, 61%, HbSA = 15, 39%) from Chiapas (67%) and Guerrero (33%), peripheral blood was collected in ethylenediamine tetraacetic acid (EDTA) for molecular and hematological studies, DNA was isolated by salting-out technic and genotyping was performed through allelic discrimination by real time polymerase chain reaction (RT-PCR) using Taqman® probes for 15 SNV (in BCL11A: rs6706648, rs7557939, rs4671393, rs11886868, rs766432, rs7599488, rs1427407; HBS1L-MYB: rs28384513, rs7776054, rs9399137, rs4895441, rs9402686, rs1320963; HBG2: rs7482144; and HBBP1: rs10128556). The obtained data were analyzed using IMB SPSS v.22.0 software. All minor alleles were observed in frequencies over 0.05, the most frequent was rs9402686 (0.82), while the less frequent was rs101028556 (0.08). In HbSS group, the mean fetal hemoglobin was 11.9 ± 5.9% and was significantly elevated in BCL11A rs11886868 wildtype homozygotes and in carriers of HBS1L-MYB intergenic region rs7776054 (p = 0.04 and p = 0.03, respectively). In conclusion, in HbSS Mexican patients, two SNVs were observed related to increased HbF; BCL11A rs11886868 and HBS1L-MYB rs7776054.

Sickle cell anemia (SCA) is one of the most common types of hemoglobinopathies in people of African ancestry, it is caused by homozygosity of HbS mutation (HBB:c.20A>T). It is known that fetal hemoglobin plays a key role in decreasing HbS polymerization which damages the erythrocyte structure and is responsible for the characteristic hemolytic crises endured by these patients. Single-nucleotide variant (SNV) in genes that regulate fetal hemoglobin (HbF) after birth have been associated with its increment, thus ameliorating the hematologic phenotype of this pathology and other ß-hemoglobinopathies. Therefore, in this study, we identified, for the first time in Mexican patients with SCA (HbSS) and HbS carriers (HbSA), the presence of 15 SNVs on BCL11A, HBS1L-MYB and HBG2; all HbSS patients had anemia and elevated HbF; 2 variants were related to increased HbF rs11688888C of BCL11A and rs7776054G of HBSIL-MYB; and finally, all minor alleles were found at a frequency higher than 0.05.

Can there be a common, risk-based framework for decisions around live insect trade?

A network of scientists involved in shipment of live insects has met and generated a series of articles on issues related to live insect transport. The network is diverse, covering large-scale commercial interests, government operated areawide control programmes, biomedical research and many smaller applications, in research, education and private uses. Many insect species have a record of safe transport, pose minimal risks and are shipped frequently between countries. The routine shipments of the most frequently used insect model organism for biomedical research, Drosophila melanogaster, is an example. Successful large scale shipments from commercial biocontrol and pollinator suppliers also demonstrate precedents for low-risk shipment categories, delivered in large volumes to high quality standards. Decision makers need access to more information (publications or official papers) that details actual risks from the insects themselves or their possible contaminants, and should propose proportionate levels of management. There may be harm to source environments when insects are collected directly from the wild, and there may be harm to receiving environments. Several risk frameworks include insects and various international coordinating bodies, with experience of guidance on relevant risks, exist. All stakeholders would benefit from an integrated overview of guidance for insect shipping, with reference to types of risk and categories of magnitude, without trying for a single approach requiring universal agreement. Proposals for managing uncertainty and lack of data for smaller or infrequent shipments, for example, must not disrupt trade in large volumes of live insects, which are already supporting strategic objectives in several sectors.

À l'occasion d'une réunion d'experts, un réseau de chercheurs travaillant sur l'expédition d'insectes vivants a produit un ensemble d'articles traitant des questions liées au transport des insectes vivants. Ce réseau est diversifié et représente un large éventail d'intérêts privés et de programmes de lutte biologique à grande échelle menés par les pouvoirs publics, en plus du secteur de la recherche biomédicale et de nombreux acteurs intervenant dans des applications de plus petite envergure relevant de la recherche, de l'enseignement ou du secteur privé. Un grand nombre d'espèces d'insectes sont transportées en toute sécurité avec un niveau de risque minimal, y compris lors des fréquentes expéditions internationales. Un exemple de ces expéditions régulières concerne l'espèce la plus utilisée par la recherche biomédicale en tant qu'organisme modèle, à savoir Drosophila melanogaster. Les exemples réussis d'expéditions à grande échelle provenant de fournisseurs d'agents de lutte biologique et de pollinisateurs produits par le secteur privé offrent également un relevé documenté des diverses catégories d'expéditions à faible risque pour des livraisons d'insectes vivants en grandes quantités et répondant à des normes de qualité élevées. Les décideurs politiques devraient pouvoir accéder à plus d'informations (à travers des publications ou des articles officiels) décrivant en détail les risques réels associés aux insectes eux-mêmes ou à leurs contaminants éventuels, et proposer en connaissance de cause des niveaux de gestion proportionnels à ces risques. La récolte d'insectes prélevés directement de la nature peut être dommageable aussi bien pour les environnements source que pour ceux de destination. Plusieurs cadres fondés sur le risque intègrent désormais les insectes dans leurs directives. Par ailleurs, nombre d'organismes internationaux de coordination ont acquis une expérience dans l'élaboration de lignes directrices face à ces risques. Il serait bénéfique pour toutes les parties prenantes de disposer d'une vue d'ensemble intégrée des directives applicables aux expéditions d'insectes, qui recense les différents types de risque et leurs ordres de grandeur sans se prononcer sur une approche unique qui nécessiterait une adhésion universelle. Ni les propositions visant à gérer l'incertitude ni l'insuffisance des données disponibles sur les expéditions d'insectes en petits nombres ou occasionnelles ne doivent perturber les échanges commerciaux d'insectes vivants en grandes quantités, échanges qui participent aujourd'hui aux objectifs stratégiques de nombreux secteurs.

Una red de científicos relacionados de un modo u otro con el transporte de insectos vivos mantuvo un encuentro y generó una serie de artículos en torno a la cuestión. En la red, muy heterogénea, convergen desde intereses comerciales de gran calado hasta programas públicos de lucha biológica en grandes territorios, pasando por la investigación biomédica y por numerosas aplicaciones de menor dimensión en ámbitos como la investigación, la enseñanza u otros usos privados. Muchas especies de insectos cuentan con un buen historial de seguridad en el transporte, presentan un riesgo mínimo y son expedidas a menudo de un país a otro. Buen ejemplo de ello son los envíos sistemáticos de ejemplares de Drosophila melanogaster, que es el insecto utilizado con más frecuencia como organismo modelo en la investigación biomédica. Otro precedente de envíos voluminosos cuyo transporte y entrega se ajusta a los más exigentes criterios de calidad lo sientan las remesas de grandes cantidades de polinizadores y agentes de control biológico remitidos por proveedores comerciales. Los responsables de adoptar decisiones deben disponer de más y más detallada información (publicaciones o documentos oficiales) sobre los riesgos reales derivados de los propios insectos o sus posibles contaminantes para proponer a partir de ahí medidas de gestión proporcionadas. Los perjuicios ambientales pueden darse tanto en origen (cuando hay captura salvaje de insectos, o sea recolección directa en el medio) como en destino. Hay varios sistemas de determinación del riesgo que incluyen a los insectos y también existen diversos organismos de coordinación internacional que ya tienen experiencia en sentar pautas sobre los riesgos en la materia. Todos los interlocutores del sector se beneficiarían de una visión global e integrada del transporte de insectos, que remita a diferentes tipos de riesgo y categorías de magnitud, sin necesidad de buscar un sistema único que exija consenso universal. Las propuestas para gestionar la incertidumbre y la falta de información en el caso de envíos infrecuentes o de pequeñas dimensiones, por ejemplo, no deben interferir en el transporte de grandes cantidades de insectos vivos, que ya está sirviendo a objetivos estratégicos en varios sectores.

The World Organisation for Animal Health - current and potential roles in safe international trade of bees and other insects.

The World Organisation for Animal Health (WOAH, founded as OIE) is the recognised intergovernmental standard-setting organisation for animal health and welfare. The WOAH mandate is to support its members in the prevention of the spread of animal diseases of concern, as listed in the Terrestrial Animal Health Code (Terrestrial Code). Once a disease, infection or infestation is listed, national Veterinary Authorities have the obligation regularly to notify WOAH of the presence or absence of the listed disease. In regard to insects, the scope of the Terrestrial Code limits its recommendations to preserving the health of bees (species of the genus Apis, extended to the genus Bombus and to the stingless bees for one disease). However, it does not include standards to mitigate the potential animal health risks associated with the international trade of other insects. A description of the standard-setting process and a review of the history of the standards for bee health highlight the resources and requirements to expand the scope of the Terrestrial Code to include recommendations for animal health risk mitigation measures for the safety of international trade in insects. Any initiative to develop guidance on insect trade should include WOAH in its role as the sole global standard-setting organisation on animal health and welfare matters. This aligns with the WOAH commitment to a One Health approach.

L'Organisation mondiale de la santé animale (OMSA, fondée en tant qu'OIE) est l'organisation inter-gouvernementale reconnue pour l'élaboration de normes relatives à la santé et au bien-être des animaux. L'OMSA a pour mandat d'apporter un soutien à ses Membres afin de prévenir la propagation des maladies animales d'importance majeure listées dans le Code sanitaire pour les animaux terrestres (Code terrestre). Dès lors qu'une maladie, une infection ou une infestation figure sur cette liste, les Autorités vétérinaires ont l'obligation de notifier régulièrement à l'OMSA la présence ou l'absence de cette maladie sur leur territoire. S'agissant des insectes, le champ d'application du Code terrestre limite ses recommandations à la préservation de la santé des abeilles (espèces du genre Apis, avec l'inclusion du genre Bombus et des abeilles sans dard pour une maladie). Néanmoins, le Code terrestre ne contient pas de normes visant à atténuer les risques pour la santé animale associés aux échanges internationaux d'autres insectes. La description faite par les auteurs du processus d'élaboration des normes et leur aperçu rétrospectif de la mise au point des normes relatives à la santé des abeilles font ressortir les ressources et les conditions nécessaires pour élargir le champ d'application du Code terrestre afin d'y inclure des recommandations portant sur les mesures d'atténuation des risques pour la santé animale applicables à la sécurité sanitaire des échanges internationaux d'insectes. Toute initiative visant à fournir des orientations sur les échanges d'insectes devrait inclure l'OMSA dans son rôle d'unique organisation chargée de l'élaboration des normes internationales relatives à la santé animale et au bien-être des animaux. Cette exigence est en cohérence avec l'engagement de l'OMSA en faveur de l'approche Une seule santé.

La Organización Mundial de Sanidad Animal (OMSA, fundada como OIE) es la organización intergubernamental facultada para ejercer funciones normativas en materia de sanidad y bienestar de los animales. La OMSA tiene por mandato ayudar a sus miembros a prevenir la propagación de una serie de enfermedades animales de importancia, recogidas en el Código Sanitario para los Animales Terrestres (Código Terrestre) de la OMSA. La inclusión de una enfermedad, infección o infestación en la lista de la OMSA obliga a las autoridades veterinarias nacionales a dar cuenta periódicamente a la OMSA de la presencia o ausencia de esa patología en su territorio. Por lo que respecta a los insectos, en el Código Terrestre solo se formulan una serie de recomendaciones para proteger la salud de las abejas (categoría que corresponde a las especies del género Apis, extensible también al género Bombus y, en el caso de una enfermedad, a las abejas sin aguijón). El Código Terrestre, sin embargo, no contiene norma alguna destinada a mitigar los posibles riesgos zoosanitarios ligados al comercio internacional de otros insectos. Los autores describen el proceso normativo y repasan la historia de las normas relativas a la sanidad de las abejas, con lo que ponen de relieve los recursos y demás elementos necesarios para conferir mayor alcance al Código Terrestre incluyendo en él recomendaciones sobre medidas de mitigación del riesgo zoosanitario para un comercio seguro de insectos a escala internacional. Toda iniciativa encaminada a marcar pautas sobre el comercio de insectos debería incluir a la OMSA, única organización con potestad normativa mundial sobre temas de sanidad y bienestar de los animales, lo que además se encuadra en el compromiso de la OMSA con los planteamientos de «Una sola salud¼.

Impact of a Maternal Motivational Interviewing on Oral Health in the Mother-Child Dyad.

Motivational Interviewing (MI) has been included in dentistry programs. There exists a need for interventions in the mother-child dyad. The aim of this paper was to compare the effects of a MI-based educational program on oral care knowledge, attitudes, and practices (KAP) in the mother-child dyad to a Traditional Education-based program (TE). A community intervention trial was carried out. The experimental and control groups were made up of women between 18 and 45 years of age in the sixth month of gestation. Both groups were provided with TE. The experimental group additionally received a session based on the principles of the MI. Socio-demographic data, children's oral health KAP (COHKAP), that of the mother (MOHKAP), and maternal self-efficacy (MSE) in relation to children's oral health (COHMSE) were recorded. A baseline measurement was made, as well as a six-month follow up. The participants included 135 women with an average age of 24.88 ± 6.00. After intervention, the experimental group's COHKAP, MOHKAP, and COHMSE all increased (p < 0.001). When MI-based interventions are combined with TE, MSE and dental care KAP for the mother-child dyad in pregnant women can be improved.
