Summary: The state of Chiapas presents degradation processes of dif ferent kinds, as a consequence of the current established agricultural model. It is estimated that, in the near future, the surface of the state of Chiapas will present more than 55% degradation, generating changes in the physical, chemical and biological properties of the soil, af fecting the quality of life of human beings, mainly due to scarcity of food. The objective of this research was to evaluate the quality of the soils in three municipalities of the central depression of Chiapas, Mexico. The analysis were interpreted taking NOM-021-SEMARNAT-2000 as a reference and were classified according to the world reference base (WRB), version 2014. For the evaluation of soil quality, the sustainable use of land subindex (SUSS). 144 soil samples corresponding to 21 profiles were analyzed. Of the 21 profiles studied, 17 present poor soil qualities, two a sensitive quality, one acceptable quality and one with good quality. Only two soil groups presented good fertility and are classified as Vertisols and Phaeozems, which present good quality and capacity to maintain sustainable agricultural production in this region.

Resumen: El estado de Chiapas presenta procesos de degradación de diferente índole, como consecuencia del actual modelo agrícola establecido. Se estima que, en el futuro cercano, la superficie del estado de Chiapas presente más de 55% de degradación, generando modificaciones en las propiedades físicas, químicas y biológicas del suelo; afectando la calidad de vida de los seres humanos, principalmente por escasez de alimentos. El objetivo de esta investigación fue evaluar la calidad de los suelos en tres municipios de la depresión central de Chiapas, México. Los análisis se interpretaron tomando como referencia la NOM-021-SEMARNAT-2000 y se clasificaron de acuerdo con la world reference base (WRB), versión 2014, para la evaluación de calidad del suelo se utilizó el subíndice de uso sustentable del suelo (SUSS). Se analizaron 144 muestras de suelo correspondientes a 21 perfiles. De los 21 perfiles estudiados, 17 presentan calidad de suelo pobre, dos calidades sensibles, uno calidad aceptable y uno con calidad buena. Solo dos Grupos de suelo presentaron buena fertilidad y son clasificados como Vertisols y Phaeozems, los cuales presentan buena calidad y capacidad para mantener producción agrícola sostenible en esta región.

Resumen Introducción: La fenilcetonuria es el trastorno hereditario más frecuente del metabolismo de los aminoácidos y su abordaje suele centrarse en dietas restringidas en fenilalanina, un aminoácido presente en el edulcorante aspartamo habitualmente usado como excipiente en tecnología farmacéutica. Objetivo: El objetivo principal es la revisión de los medicamentos sin receta comercializados en España hasta marzo de 2023 y que contienen aspartamo en su composición. Método: Se realizó una revisión en la base de datos BOT plus de todos los medicamentos comercializados en España que contienen aspartamo. Se seleccionaron solo los MSR. Se consultaron las fichas técnicas en el Centro de información online de medicamentos de la AEMPS (CIMA), y los datos obtenidos se registraron en una tabla. Resultados: Se obtuvieron 570 medicamentos; 58 eran MSR. Cuando exista petición de MSR con aspartamo en pacientes con fenilcetonuria, en el SIF, tras su evaluación, en el 100% de los casos, el farmacéutico aplicando el Servicio de Indicación Farmacéutica podría indicar un MSR alternativo, con el mismo principio activo pero sin aspartamo como excipiente. Conclusiones: La actuación del farmacéutico comunitario para aplicar el SIF es muy importante en pacientes con fenilcetonuria. Existen medicamentos que no requieren prescripción y se pueden indicar en estos pacientes. El farmacéutico debe tener a su disposición las herramientas necesarias que le faciliten el SIF con este tipo de enfermos.

Abstract Introduction: Phenylketonuria is the most common inherited disorder of amino acid metabolism and its management usually focuses on diets restricted in phenylalanine, an amino acid present in the sweetener aspartame commonly used as an excipient in pharmaceutical technology. Objective: The main objective is the review of non-prescription medicines marketed in Spain until March 2023 and that contain aspartame in their composition. Methods: A review of all medicines marketed in Spain containing aspartame was carried out in the BOT plus database. Only MSRs were selected. The data sheets were consulted at the AEMPS online medicines information centre (CIMA), and the data obtained were recorded in a table. Results: 570 medicines were obtained; 58 were MSRs. When there is a request for MSRs with aspartame in patients with phenylketonuria, in the SIF, after evaluation, in 100% of the cases, the pharmacist applying the Pharmaceutical Indication Service could indicate an alternative MSR, with the same active ingredient but without aspartame as an excipient. Conclusions: The action of the community pharmacist to apply the SIF is very important in patients with phenylketonuria. There are medicines that do not require a prescription and can be prescribed for these patients. Pharmacists should have the necessary tools at their disposal to facilitate the SIF with this type of patient.

Background: The diagnosis of an oncological disease exposes people to a greater state of vulnerability and health care models are not focused on their subjective needs. In this scenario, the primary nurse becomes a professional who contributes to the comprehensive care of people with cancer. Aim: To understand the lived experience of patients with cancer undergoing chemotherapy treatment, when being cared for by a primary nurse. Material and Methods: Qualitative phenomenological study. Nine cancer survivors who were cared for by primary nurses during chemotherapy were interviewed. Results: The analysis revealed two comprehensive categories, namely experiences around becoming ill with cancer, and experiences when navigating the health system, each with subcategories. Conclusions: This study demonstrates the impact that personalized attention focused on people's needs has on their lives. It also contributes to visualize the work of primary nurses in the care and accompaniment of patients with cancer and their families. The need for specialized professionals such as Advanced Practice Nursing is underlined.

PAHO/WHO proposes to implement the role of Advanced Practice Nurse (APN) in Latin America, to reduce gaps in coverage and access to health care. For this purpose, it is necessary to train nursing professionals with an expanded role, which allows them to collaborate in the diagnosis, treatment, and monitoring of people with specific diseases, under established protocols and clinical guidelines and within consolidated interdisciplinary health teams in a cost-effective way. One of the areas with the greatest coverage deficit in Latin America is adult oncology, with inequality in care opportunities for these patients. Part of the premature deaths attributable to this disease are due to the lack of access to timely diagnosis and treatment. As a contribution to the reduction of this gap, a training program of Advanced Nursing Practice was developed, addressing the most urgent needs in the field of oncology. The necessary competencies were defined to develop a professional-level master’s degree program, considering prevention, early detection, diagnosis, treatment, and monitoring of people with oncological diseases at different levels of care. A program of this kind is an opportunity to reduce the access gap and coverage of health care for people with cancer, improving their quality of life and their survival.

RESUMO Este estudo teve como objetivo investigar os comportamentos antecipatório e de tempo de reação do goleiro. Para este fim foram analisados 50 chutes executados por jogaores de futsal. O tempo de resposta do goleiro a um chute foi analisado em relação ao resultado do chute, à zona da quadra e à distância entre o goleiro e o jogador que executou o chute. Os comportamentos de antecipação e tempo de reação do goleiro foram considerados, respectivamente, como aqueles executados abaixo e acima de 200 ms considerando o início do movimento do chutador e o início do movimento do goleiro. Os resultados mostraram que o goleiro executou comportamentos antecipatórios predominantemente quando (i) ocorreram gols, (ii) os chutes foram executados das zonas central e de ataque, (iii) de distâncias entre 5,97 a 7,84 metros. Nestas condições, os comportamentos antecipatórios do goleiro implicaram em performances ineficazes.

ABSTRACT This study aimed to investigate the goalkeeper’s anticipatory and reaction time behaviors. For this purpose, 50 kicks performed by male futsal players were analyzed. The time of goalkeeper’s response to a kick was analyzed in relation to the kick outcome, court zone and distance between the goalkeeper and player who performed the kick. The goalkeeper’s anticipation and reaction time behaviors were those below and above 200 ms as the time criterion, respectively, by considering the moment the player began the preparation for kicking to the moment the goalkeeper began to respond to it. Results showed that the goalkeeper performed anticipatory behaviors predominantly when (i) goals were attained and (ii) kicks were performed in the center and attack court’s zones (iii) at a distance ranging from 5.97 to 7.84 meters. In these conditions, the goalkeepers’ anticipatory behaviors implied ineffective performances.

Abstract To identify this increasingly common pathology, known as Multiple Myeloma, it is necessary to refer to the specific factors that characterize it; to this end, the classic criteria known as CRAB (hypercalcemia, renal failure, anemia and lytic lesions) are available, in which renal failure is one of the most frequent complications. Recently, 3 indisputable biomarkers have been described for the diagnostic support for Multiple Myeloma, which are: more than 10% of clonal plasma cells in BM or, a biopsy that corroborates the presence of a plasmacytoma, light chain ratio ≥100 mg/dL and more than one focal lesion on magnetic resonance imaging (MRI). A differential diagnosis for plasma cell leukemia, solitary bone plasmacytoma, and extramedullary plasmacytoma should always be considered. Being this an incurable disease, a lot of research has been done regarding its therapeutic management, whose main objective is the disappearance of plasma cells and the patient clinical improvement. Melphalan was the first drug that showed a benefit in 1958 and afterwards, with the addition of a steroid as a second drug, it was possible to improve response rates. Subsequently, different molecules were studied, forming multiple combinations, and achieving better rates of Overall Survival and Progression-Free Survival. Years later, with the arrival of proteasome inhibitors such as bortezomib, and immunomodulators such as thalidomide and lenalidomide, an important turnaround in the disease has been seen, as deeper responses, more prolonged remissions, and improvement in the quality of life of patients have been achieved. This consensus has the purpose of integrating a group of Mexican specialists and promoting the updating of this pathology.

Abstract: Background: Dermatological diseases are among the primary causes of the demand for basic health care. Studies on the frequency of dermatoses are important for the proper management of health planning. Objectives: To evaluate the nosological and behavioral profiles of dermatological consultations in Brazil. Methods: The Brazilian Society of Dermatology invited all of its members to complete an online form on patients who sought consultations from March 21-26, 2018. The form contained questions about patient demographics, consultation type according to the patient's funding, the municipality of the consultation, diagnosis, treatments and procedures. Diagnostic and therapeutic decisions were compared between subgroups. Results: Data from 9629 visits were recorded. The most frequent causes for consultation were acne (8.0%), photoaging (7.7%), nonmelanoma skin cancer (5.4%), and actinic keratosis (4.7%). The identified diseases had distinct patterns with regard to gender, skin color, geographic region, type of funding for the consultation, and age group. Concerning the medical conducts, photoprotection was indicated in 44% of consultations, surgical diagnostic procedures were performed in 7.3%, surgical therapeutic procedures were conducted in 19.2%, and cosmetic procedures were performed in 7.1%. Study limitations: Nonrandomized survey, with a sample period of one week. Conclusion: This research allowed us to identify the epidemiological profiles of the demands of outpatients for dermatologists in various contexts. The results also highlight the importance of aesthetic demands in privately funded consultations and the significance of diseases such as acne, nonmelanoma skin cancer, leprosy, and psoriasis to public health.

Abstract: Background: Inhibition of quorum sensing systems (QSS-I) is a novel strategy in the treatment of bacterial infections. To date, plants are the major source of metabolites with this inhibitory activity. Thus, species of Mexican flora can be important resources for obtaining metabolites with QSS-I activity. Hypothesis: We hypothesized that extracts from species of the genus Ceiba have metabolites with inhibitory activity against bacterial quorum sensing systems. Species studied: Ceiba pentandra (L.) Gaertn. and Ceiba aesculifolia (Kunth) Britten & Baker f. (Malvaceae). Study site and years of study: We collected Ceiba bark in the municipalities of Tierra Blanca, Veracruz, and Acatlan, Oaxaca, in August 2013. Methods: We determined the effect of extracts from C. aesculifolia and C. pentandra against QSS-regulated phenotypes of Chromobacterium violaceum and Pseudomonas aeruginosa. Extracts were fractionated and the main metabolites were identified. As support in the identification of the species, we carried out an anatomical study of the bark. Results: Hexane and dichloromethane extracts of both species of Ceiba exhibited QSS-I activity. We identified four fractions rich in terpene and sterol compounds with the ability to attenuate virulence factors in P. aeruginosa. The histological analysis appears to support the presence of some differences in the barks that can facilitate identification of the two species. Conclusions: The extracts and fractions of the two species of Ceiba are sources of phytochemicals with the ability to regulate bacterial quorum sensing systems positively or negatively.

Resumen: Antecedentes: la inhibición de los sistemas de percepción de quórum (I-SPQ) es una nueva estrategia en el tratamiento de infecciones bacterianas. Hasta la fecha, las plantas son la principal fuente de metabolitos con esta actividad inhibidora. Por lo tanto, las especies de flora mexicana pueden ser fuentes importantes para obtener metabolitos con actividad I-SPQ. Hipótesis: los extractos de especies del género Ceiba tienen metabolitos con actividad inhibidora contra los sistemas de percepción de quórum bacteriano. Especies estudiadas: Ceiba pentandra (L.) Gaertn. y Ceiba aesculifolia (Kunth) Britten & Baker f. (Malváceas). Lugar de estudio y años de estudio: Recolectamos las cortezas de Ceiba en los municipios de Tierra Blanca, Veracruz y Acatlán, Oaxaca, en agosto de 2013. Métodos: Determinamos el efecto de extractos de C. aesculifolia y C. pentandra contra fenotipos regulados por SPQ de Chromobacterium violaceum y Pseudomonas aeruginosa. Los extractos se fraccionaron y se identificaron los principales metabolitos. Como apoyo en la identificación de la especie, realizamos un estudio anatómico de la corteza. Resultados: los extractos de hexano y diclorometano de ambas especies de Ceiba exhibieron actividad I-SPQ. Identificamos cuatro fracciones ricas en compuestos de la clase de los terpenos y esteroles con la capacidad de atenuar los factores de virulencia en P. aeruginosa. El análisis histológico parece apoyar la presencia de algunas diferencias en las cortezas que pueden facilitar la identificación de las dos especies. Conclusiones: Los extractos y fracciones de las dos especies de Ceiba son fuentes de fitoquímicos con la capacidad de regular positiva o negativamente los sistemas de percepción de quórum bacteriano.

One of the major changes made by virtue of the updating of the Cuban economic and social model has been the establishment of non-agricultural cooperatives. This paper examines the characteristics of these, determines their potential for and obstacles to their development, and whether or not they are operating according to the basic cooperative principles. For this, apart from consulting the main literature thereon, a sample of members of construction industry cooperatives was surveyed in several municipalities of Havana. This paper starts from some conceptual considerations, examines the characteristics of cooperatives, particularly the ones in the Cuban construction industry, their potential and trouble, and lays down some guidelines intended to contribute to their development.

Una de las principales transformaciones de la actualización del modelo económico y social cubano ha sido la creación de cooperativas no agropecuarias (CNA), siendo el sector de la construcción uno de los más representativos. El presente artículo analiza sus características, determina las potencialidades y barreras para su desarrollo y pone de manifiesto el estado actual de cumplimiento de los principios del cooperativismo al interior de las cooperativas. Para ello, además de la consulta obligada a las principales referencias bibliográficas del tema, se aplicó una encuesta a una muestra de cooperativistas de la construcción en varios municipios de la capital. El trabajo parte de algunas consideraciones conceptuales, luego caracteriza las CNA en el país y, particularmente, las de construcción; finalmente analiza sus principales potencialidades y barreras, esbozando posibles líneas de acción para contribuir a su desarrollo armónico.

Abstract: The medical-dermatological demographics favors health planning and guides expansion of the specialty. We conducted an ecological study of dermatologists members of the Brazilian Society of Dermatology (SBD). We evaluated: gender, age, address; which were compared with population and human development index indicators of municipalities. We evaluated 8384 members, distributed in 527 (9.5%) municipalities throughout Brazil. The female sex represented 78.4% of the members and the median age was 43 (36-54) years. The median density of dermatologists was 0.35 (0.21-0.37) per 10,000 inhabitants. The correlation (Spearman's rho) between density of dermatologists and human development index was 0.39 (p <0.01). The Brazilian dermatologist is characterized as: female, age <50 years and presenting an heterogeneous distribution throught the country.

Abstract Introduction: Panoramic radiography and cone beam computed tomography (CBCT) are very important in the diagnosis of oral diseases, however patients are exposed to the risk of ionizing radiation. This paper describes our study aimed at comparing absorbed doses in the salivary glands and thyroid due to panoramic radiography and CBCT and estimating radiation induced cancer risk associated with those methods. Methods Absorbed doses of two CBCT equipment (i-CAT® Next Generation and SCANORA® 3D) and a digital panoramic device (ORTHOPANTOMOGRAPH® OP200D) were measured using thermoluminescent dosimeters loaded in an anthropomorphic phantom on sublingual, submandibular, parotid and thyroid glands. Results Absorbed doses in the i-CAT® device ranged between 0.02 (+/-0.01) and 2.23 mGy (+/-0.03), in the SCANORA™ device ranged from 0.01 (+/-0.01) to 2.96 mGy (+/-0.29) and in the ORTHOPANTOMOGRAPH® OP200D ranged between 0.04 mGy and 0.78 mGy. The radiation induced cancer risk was highlighted in the salivary glands, which received higher doses. The protocols that offer the highest risk of cancer are the high resolution protocols of CBCT equipment. Conclusion CBCT exposes patients to higher levels of radiation than panoramic radiography, so the risks and benefits of each method should be considered. The doses in CBCT were dependent on equipment and exposure parameters, therefore adequate selection minimizes the radiation dose.

Background: Knowing nurses’ workload in hemodialysis units allows a better organization of human resources. Aim: To determine nurses’ workload according to dependence and risk profiles of patients undergoing chronic hemodialysis. Material and Methods: One hundred fifty one patients from five hemodialysis units were selected and categorized in terms of dependence and risk using the instrument “Care according to dependence and risk in hemodialysis (CUDYR-DIAL). Nurses’ activities for direct and indirect care and the time taken to complete those activities were measured. Results: Per patient, nurses used 36.5 ±10.7 min for direct and 23.6 min for indirect care. The time required for direct care of patients at high risk with partial dependence and at high risk and partial self-sufficiency was 41.2 and 40.3 minutes respectively. Conclusions: During a dialysis session, nurses occupy 60% of their time providing direct care, mainly directed to patients categorized as being of high risk-partial dependence and high risk-partial self-sufficiency.
