Resumo O uso de produtos naturais obtidos de plantas, por exemplo, as plantas invasoras, oferece uma variedade de aleloquímicos com potencial fungicida. Tendo isso em vista, objetivou-se avaliar o potencial fungicida de extratos etanólicos de plantas do Cerrado sobre Rhizoctonia solani e Macrophomina phaseolina. Foi preparado o extrato hidroalcoólicos etanólico das 12 plantas apontadas como invasoras no Cerrado brasileiro (Anacardium humile Saint Hill; Baccharis dracunculifolia DC.; Cenchrus echinatus L; Commelina erecta L.; Erigeron bonariensis L.; Digitaria horizontalis Willd.; Digitaria insularis L.; Porophyllum ruderale Jacq. Cass; Richardia brasiliensis Gomes; Sida rhombifolia L.; Turnera ulmifolia L.; Smilax fluminensis Steud) e foi realizado o screening fitoquímico e a determinação de fenóis e flavonoides totais. Para avaliar a atividade antifúngica in vitro, as soluções hidroalcóolicas nas concentrações de 800, 1200, 1600, 2000 e 2400 µL 100 mL-1 foram incorporadas, separadamente, em ágar BDA, e vertidas em placa de Petri, seguido do disco de micélio do fungo. Como controle, foram preparadas duas soluções, uma solução etanólica adicionada ao meio BDA (2400 µg 100 mL-1), e outra somente com meio BDA, a testemunha. Foram vertidas em placas de Petri, seguido um disco de 0,5 cm de diâmetro de micélio do fungo, incubados (23±2 ºC), com fotoperíodo de 24 horas. Dentre os constituintes encontrados nas plantas, 75% estão os compostos fenólicos, 58,3% estão os heterosídeos cardiotônicos, 50% estão os esteroides, 33,3% estão os flavonoides, 16,7% estão as antraquinonas e 8,3% estão os alcaloides, saponinas e açúcares redutores. Das 12 espécies, apenas os extratos de C. erecta e R. brasiliensis foram ativos para M. phaseolina e R. solani. Desse modo, conclui-se que o extrato etanólico de C. erecta apresenta potencial fungicida para controle de doenças causadas por fungos habitantes do solo. Das demais espécies, a A. humille, B. dracuncufolia, D. insulares, C. erecta, D. insulares, P. ruderale e R. brasiliensis possuem potencial fungitóxicos naturais por destacarem nos teores de polifenóis eficientes na redução do crescimento micelial de M. phaseolina e R. solani.

Abstract The use of natural products obtained from plants, for example, invasive plants, offers a variety of allelochemicals with fungicidal potential. With this in perspective, the objective was to evaluate the fungicidal potential of ethanolic extracts of Cerrado plants on Rhizoctonia solani and Macrophomina phaseolina. The ethanolic hydroalcoholic extract of the 12 plants identified as invaders in the Brazilian Cerrado was prepared (Anacardium humile Saint Hill; Baccharis dracunculifolia DC.; Cenchrus echinatus L; Commelina erecta L.; Erigeron bonariensis L.; Digitaria horizontalis Willd.; Digitaria insularis L.; Porophyllum ruderale Jacq. Cass; Richardia brasiliensis Gomes; Sida rhombifolia L.; Turnera ulmifolia L.; Smilax fluminensis Steud)) and phytochemical screening and determination of total phenols and flavonoids were performed. To evaluate the in vitro antifungal activity, the hydroalcoholic solutions at concentrations of 800, 1200, 1600, 2000, and 2400 µL 100 mL-1 were separately incorporated into BDA agar and poured into Petri dishes, followed by the mycelium disk of the fungus. As a control, two solutions were prepared, one ethanolic solution added to the BDA medium (2400 µg 100 mL-1) and the other with BDA medium only. They were poured into Petri dishes, followed by a 0.5 cm diameter disk of mycelium of the fungus, incubated (23±2 ºC), with a 24-hour photoperiod. Among the constituents found in the plants, 75% are phenolic compounds, 58.3% are cardiotonic heterosides, 50% are steroids, 33.3% are flavonoids, 16.7% are anthraquinones, and 8.3% are alkaloids, saponins, and reducing sugars. Out of the 12 species, only the extracts of C. erecta and R. brasiliensis were active for M. phaseolina and R. solani. Thus, it is concluded that the ethanolic extract of C. erecta has the fungicidal potential to control diseases caused by fungi that are soil inhabitants. Of the other species, A. humille, B. dracuncufolia, D. insulares, C. erecta, D. insulares, P. ruderale, and R. brasiliensis have natural fungitoxic potential because they stand out in the content of polyphenols efficient in reducing the mycelial growth of M. phaseolina and R. solani.

ABSTRACT Introduction: HIV/AIDS is considered one of the great cases of public health, but it is seen that patients who use antiretroviral therapy (ART) and practice strength training promote a promotion of their health. Objectives: Assess the impact of strength and resistance training on cytokines and body composition in people living with HIV/AIDS. Methods: Randomized clinical trial, the sample consisted of 12 patients, 7 from the Strength Group (GF) and 5 from Group 2, Muscular Resistance (MGR). We compared the levels of IL-2, IL-4, IL-6, IL-10 and TNF-α cytokines and body composition in the first and last sessions. The patients completed 36 strength and resistance training sessions over 12 weeks. Results: After 36 sessions of GRM resistance training, there was a significant increase from 4,734 pg/mL to 5,050 pg/mL of IL-10 (p=0.002). Regarding the GFR, no significant results were found. For body composition, there were significant differences in GFR due to the increase in lean mass of the arms from 6,441g to 7,014g (p=0.04), legs from 16,379g to 17,281g (p=0.02) and whole body of 45,640g to 47,343g (p=0.01). In G2 there was a significant decrease in the percentage of fat in the arms from 23,160% to 20,750% (p = 0.04). To assess quality of life, the WHOQOL-HIV-Bref questionnaire was used, where significant improvement was found in all domains, except for the level of independence domain. Conclusion: We conclude that muscular resistance training is effective in increasing IL-10 and decreasing the percentage of fat in the arms, whereas strength training increases lean mass in arms, legs, and the whole body. Level of Evidence I; Randomized Clinical Trial.

BACKGROUND: There is a recognised need for rehabilitation services at primary health care (PHC) level. In addition, there are clear policies (international and national) and guidelines for use by healthcare planners in South Africa to implement rehabilitation services. Although rehabilitation services are provided on the primary platform, its operationalisation has not been in an integrated manner. Clarity on the level of integration within existing PHC rehabilitation service delivery is required for its inclusion in a reengineered PHC AIM: The study explored the extent to which rehabilitation services are integrated into PHC service delivery based on the expressed reality of rehabilitation professionals SETTING: The Johannesburg Metropolitan District of Gauteng, South Africa METHODS: In-depth interviews with 12 PHC rehabilitation professionals were completed to elicit their experiences with PHC rehabilitation services RESULTS: The theme the current state of rehabilitation services - 'this is the reality; you need to do what you need to do' along with its two subcategories, was generated from this study. The theme describes the expressed reality of suboptimal, underdeveloped and poorly integrated rehabilitation services within the Johannesburg Metropolitan District. Rehabilitation service providers have adapted service delivery by including isolated components of rehabilitation integration models, but this has not yielded an integrated service CONCLUSION: Rehabilitation services although recognised as a crucial service in PHC must be critically analysed and adapted to develop integrated service delivery models. There should be a shift from selected coping mechanisms to targeted, integrated services CONTRIBUTION: The study describes PHC rehabilitation services and explores best practice models for integrated service planning and delivery

ABSTRACT Syphilis is a multifaceted disease that always requires differential diagnoses. A rare form of secondary syphilis is the so-called malignant syphilis characterized by necrotic ulcerated lesions covered by thick crusts with a rupioid or ostraceous appearance. Currently observed mainly in patients infected with the human immunodeficiency virus, but it was previously described in other debilitating situations such as alcoholism, y malnutrition. Eventually it can be seen in immunocompetent patients like the 2 cases we present.

RESUMEN La sífilis es una enfermedad polifacética que siempre requiere diagnósticos diferenciales. Una forma rara de la sífilis secundaria, es la llamada sífilis maligna caracterizada por lesiones ulcero necróticas cubiertas por gruesas costras de aspecto rupioide u ostráceo. Actualmente se observa principalmente en pacientes infectados por el virus de la inmunodeficiencia humana, pero anteriormente ya fue descrita en otras situaciones debilitantes como el alcoholismo, desnutrición, diabetes etc. Eventualmente puede verse en pacientes inmunocompetentes como los 2 casos que presentamos.

Abstract Mixed infection by Mycobacterium tuberculosis (Mtb) consists in the simultaneous coexistence in the same patient of two different strains of Mtb or 2 different variants of the same strain. When one of the variants selects for resistance mutations, it is called monoclonal heteroresistance (HTR); if there are 2 different strains, one sensitive and one resistant (or with different resis tance patterns), it is called polyclonal HTR. Three cases of HIV/AIDS patients are presented, all with repeated treatment adherence problems, in whom monoclonal HTR was diagnosed through Mtb complete genomic sequentiation with the coexistence of two variants of the same strain isolated from samples from lung and lymph nodes, with different resistance profiles in each case. It is important to consider the possibility of HTR, especially in patients with multiple previous therapeu tic attempts and high bacillary populations, such as in advanced AIDS, since this situation potentially com promises treatment results by coexisting sensitive and resistant variants of a strain (or strains).

Resumen Se considera infección mixta por Mycobacterium tuberculosis (Mtb) a la coexistencia en forma simul tánea y en un mismo paciente de 2 cepas diferentes de Mtb o 2 variantes distintas de la misma cepa. Cuando una de las variantes selecciona mutaciones de resistencia, se denomina heterorresistencia (HTR) monoclonal; en caso de que sean 2 cepas diferentes, una sensible y una resistente (o cepas con diferentes patrones de resistencia), se denomina HTR policlo nal. Se presentan 3 pacientes, HIV/sida, todos con reiterados problemas de adherencia al tratamiento, en los cuales a través de la secuenciación genómica completa de Mtb se diagnosticó HTR monoclonal con coexistencia de 2 variantes de la misma cepa aisladas de muestras de pulmón y ganglios linfáticos, con diferentes perfiles de resistencia en cada uno de los casos. Es importante pensar en la posibilidad de HTR, principalmente en pacientes con múltiples intentos terapéuticos previos y altas poblaciones bacilares, como en el sida avanzado, dado que esta situación compromete potencialmente los resultados del tratamiento al coexistir cepas o variantes de ce pas sensibles y resistentes.

Resumen Las enfermedades infecciosas implican problemas médicos individuales y comunitarios, por lo que requieren acciones dirigidas a procesos sociales que incidan en el bienestar de los individuos, sin perder de vista a los grupos sociales. Nos preguntamos: ¿existe relación directa entre la ética y las enfermedades infecciosas? Para dilucidar una respuesta, recordemos el periodo más álgido de la pandemia por COVID-19, cuando se emitieron guías fundamentadas en principios éticos para facilitar las decisiones médicas en la asignación de recursos escasos en periodos de máxima demanda. Al no haber un componente inclusivo con la sociedad, las decisiones que se tomaron produjeron críticas masivas, que demostraron la necesidad de analizar a detalle los criterios que se habían considerado correctos. En consecuencia, afirmamos que los principios bioéticos son trascendentales en las decisiones médicas y deben ser examinados, no solo frente al individuo, sino de cara a la salud pública (bien común e individualidad). Por otra parte, la epidemia del SIDA (síndrome de inmunodeficiencia adquirida) convive con nosotros desde hace décadas. ONUSIDA (Programa Conjunto de las Naciones Unidas sobre el VIH/SIDA) nos acerca una realidad compleja, como es que la lucha contra la enfermedad y por la salud global se interrelaciona con otros problemas como la necesidad de reducer la desigualdad, por los derechos humanos, la igualdad de género, la protección social y el desarrollo de proyectos de investigación, donde los comités de Ética en investigación en procesos comunitarios son constituyentes.

Abstract Infectious diseases socially imply individual and community medical problems. Therefore, they require actions aimed at social processes that affect the well-being of the individuals without losing sight of social groups. Faced with this panorama, we ask ourselves: is there a direct relationship between ethics and infectious diseases? To elucidate an answer, let us remember the peak period of the COVID-19 pandemic when guidelines based on ethical principles were issued to facilitate medical decisions on allocating scarce resources in periods of maximum demand. In those moments, since there was no inclusive component of society, the decisions made produced massive criticism. The reactions demonstrated the need to analyze in detail the criteria that had been considered correct. Consequently, we affirm that bioethical principles are transcendental in medical decisions and must be examined, not only for the individual but also with a view to public health. Moreover, the acquired immunodeficiency syndrome (AIDS) epidemic has lived with us for decades, and it continues to show its tragic face in the form of new cases, chronic illnesses, and deaths. Joint United Nations Programme on HIV/AIDS brings us closer to a complex reality where the fight against disease and global health are interrelated with other problems, such as the need to reduce inequality, for which human rights, gender equality, social protection, and the development of research projects, where the ethics committees in research in community processes are constituents.

RESUMEN Introducción: Un mayor conocimiento y difusión acerca del comportamiento epidemiológico de la infección por VIH en el Departamento de Itapúa genera una evidencia significativa para la toma de decisiones a nivel regional. Objetivo: Caracterizar epidemiológicamente a pacientes con VIH que forman parte del PRONASIDA del Hospital Regional de Encarnación desde el año 2017 a 2021. Material y Métodos: Estudio transversal descriptivo en pacientes con VIH captados por el PRONASIDA del Hospital Regional de Encarnación, 7ª Región Sanitaria, durante los años 2017-2021 (n=375). Los datos se expresaron en medidas de tendencia central y dispersión, y tabla de proporciones. Resultados: El mayor número de casos (80) se evidenció en los años 2018 y 2019. El rango etario de 20-29 años reportó el mayor número de casos, 20% (75), con predominancia del sexo femenino 64% (229), el 47% (177) procedente de Encarnación. Se halló un 43% (106) de casos de sida con CD4 menor a 200 células/mL, la mediana de la carga viral fue de 96.030cél/mL con un rango intercuartílico de 401.884,5cél/mL. Conclusión: Se identificó la disminución de nuevos diagnósticos en el año 2020, lo cual guarda relación con las medidas sanitarias a causa de la pandemia por COVID-19. Las características analizadas mostraron predominancia del sexo femenino en grupos etarios en edad joven con procedencia de Encarnación. Se considera importante fortalecer el primer nivel de atención en Itapúa a fin de evidenciar las brechas con el objetivo de ampliar el acceso para captación de pacientes y asegurar un diagnóstico precoz.

ABSTRACT Introduction: Increased knowledge and dissemination about the epidemiological behavior of HIV infection in the Department of Itapúa generates significant evidence for decision-making at the regional level. Objective: To describe the epidemiological characteristics of patients with HIV who are part of the PRONASIDA of the Regional Hospital of Encarnación from 2017 to 2021. Materials and Methods: Cross-sectional study conducted on HIV patients enrolled in the PRONASIDA program at the Regional Hospital of Encarnación, 7th Health Region, during the years 2017-2021 (n=375). Data were expressed in measures of central tendency and dispersion, and proportions table. Results: The highest number of cases (80) was observed in 2018 and 2019. The age range of 20-29 years reported the highest number of cases, 20% (75), predominantly among females 64% (229), with 47% (177) originating from Encarnación. Forty-three percent (106) of AIDS cases had CD4 counts lower than 200 cells/mL, with a median viral load of 96,030 cells/mL and an interquartile range of 401,884.5 cells/mL. Conclusion: A decrease in new diagnoses was identified in the year 2020, likely associated with health measures due to the COVID-19 pandemic. The analyzed characteristics showed a predominance of females in younger age groups originating from Encarnación. It is considered important to strengthen primary care in Itapúa to highlight gaps, aiming to broaden access for patient enrollment and ensure early diagnosis.

Abstract Introduction: recent studies have suggested the use of neck circumference as a parameter capable of identifying risks of cardiometabolic complications and the accumulation of truncal fat caused by both antiretroviral therapy and the lifestyle of people with the human immunodeficiency virus (HIV). Objective: to investigate the relationship between neck circumference and anthropometric indicators and to assess cardiometabolic risk and truncal obesity through proposed cut-off points. Methods: cross-sectional study including 233 people with HIV. Demographic, socioeconomic, lifestyle and clinical data were collected using a structured questionnaire. The anthropometric evaluation included: weight, height, body mass index (BMI) measurements; waist (WC), neck (NC), arm and arm muscle circumferences; triceps and subscapular skinfolds and their sum. ROC curves were constructed to determine the accuracy of NC in predicting cardiometabolic risk in people living with HIV. Results: the sample was 57.5 % male, with a mean age of 38.4 years (95 % CI: 37.2-39.7 years). NC showed a positive and significant correlation with all anthropometric variables analyzed (p < 0.05), and a higher correlation strength with WC and BMI. The NC cut-off point selected as a predictor of risk of cardiac metabolic complications and truncal obesity in women was ≥ 32.4 cm, considering both WC and BMI. For men, the NC cut-off points were different when considering WC (≥ 39.6 cm) and BMI (≥ 38.1 cm) as a reference. It is worth noting that NC performed well in ROC curve analysis for men, while in women it was a poor performance. Conclusion: NC proved to be a promising indicator in the assessment of nutrition and health of people living with HIV, especially in men.

Resumen Introducción: estudios recientes han sugerido el uso de la circunferencia del cuello como parámetro capaz de identificar los riesgos de complicaciones cardiometabólicas y la acumulación de grasa troncal causados tanto por la terapia antirretroviral como por el estilo de vida de las personas con el virus de la inmunodeficiencia humana (VIH). Objetivo: investigar la relación entre la circunferencia del cuello y los indicadores antropométricos y evaluar el riesgo cardiometabólico y la obesidad troncal a través de los puntos de corte propuestos. Métodos: estudio transversal que incluyó a 233 personas con VIH. Se recogieron datos demográficos, socioeconómicos, de estilo de vida y clínicos mediante un cuestionario estructurado. La evaluación antropométrica incluyó: medidas de peso, altura, índice de masa corporal (IMC); circunferencias de cintura (CC), cuello (CN), brazo (CA) y músculo del brazo (MCB); pliegues cutáneos del tríceps y subescapular y su suma. Se construyeron curvas ROC para determinar la precisión de la CN en la predicción del riesgo cardiometabólico en personas que viven con el VIH. Resultados: el 57,5 % de la muestra eran varones, con una edad media de 38,4 años (IC 95 %: 37,2-39,7 años). La CN mostró una correlación positiva y significativa (p < 0,05) con todas las variables antropométricas analizadas, y una mayor fuerza de correlación con la CC y el IMC. El punto de corte de la CN seleccionado como predictor de riesgo de complicaciones metabólicas cardiacas y obesidad troncular en mujeres fue ≥ 32,4 cm, considerando tanto la CC como el IMC. En el caso de los hombres, los puntos de corte de la CN fueron diferentes al considerar como referencia la CC (≥ 39,6 cm) y el IMC (≥ 38,1 cm). Cabe destacar que la CN obtuvo buenos resultados en el análisis de la curva ROC en el caso de los hombres, mientras que en el de las mujeres fue deficiente. Conclusión: la CN demostró ser un indicador prometedor en la evaluación de la nutrición y la salud de las personas que viven con el VIH, especialmente en los hombres.

ABSTRACT Understanding weed emergence and development aspects is essential in decision-making for management strategies. The study evaluated the effects of different sowing depths and light intensities on the emergence and development of the weeds Sida rhombifolia and Senna obtusifolia under field conditions. Each species constituted an experiment, and the experimental design used was completely randomized, with four replications. The treatments were arranged in a 6 x 4 factorial scheme, with the first factor corresponding to the six sowing depths (0.5; 1.0; 2.0; 4.0; 8.0, and 12.0 cm) and the second at four light intensities (100%, 70%, 50%, and 30% of sunlight). The seedling emergence was evaluated daily to obtain the emergence and emergence speed index. The height, time to floral induction, and dry matter of plants at flowering were also evaluated. When submitted to different levels of shading, S. rhombifolia seedlings emerge up to 12.0 cm deep. S. obtusifolia seedlings emerge at all sowing depths, even when subjected to different solar radiation intensities. Seedlings of S. rhombifolia and S. obtusifolia emerge less and slower in sowings between 8.0 and 12.0 cm depth and develop better under full sunlight in sowings between 1.0 and 4.0 cm depth. Therefore, greater depths delay the development of both species, which is important information for managing these weeds.

RESUMO Compreender os aspectos de emergência e desenvolvimento de plantas daninhas é essencial na tomada de decisão para estratégias de manejo. Neste trabalho foram avaliados em condições de campo, os efeitos de diferentes profundidades de semeadura e intensidades luminosas na emergência e no desenvolvimento das plantas daninhas Sida rhombifolia e Senna obtusifolia. Cada espécie constituiu um experimento e o delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições. Os tratamentos foram dispostos em esquema fatorial 6 x 4, sendo o primeiro fator correspondente as seis profundidades de semeadura (0,5; 1,0; 2,0; 4,0; 8,0 e 12,0 cm) e o segundo a quatro intensidades luminosas (100%, 70%, 50% e 30% da luz solar). Avaliou-se diariamente a emergência das plântulas para obtenção da emergência e do índice de velocidade de emergência. A altura, o tempo até a indução floral e a matéria seca das plantas no florescimento também foram avaliadas. Quando submetidas a diferentes níveis de sombreamento as plântulas de S. rhombifolia emergem em até 12,0 cm de profundidade. As plântulas de S. obtusifolia emergem em todas as profundidades de semeadura, mesmo quando submetidas a diferentes intensidades de radiação solar. As plântulas das espécies S. rhombifolia e S. obtusifolia emergem menos e em menor velocidade em semeaduras entre 8,0 e 12,0 cm de profundidade e se desenvolvem melhor em condições de luz solar plena em semeaduras entre 1,0 e 4,0 cm de profundidade. Portanto, maiores profundidades atrasam o desenvolvimento de ambas as espécies, sendo uma importante informação para o manejo dessas plantas daninhas.

Describimos el primer caso registrado en Argentina, según el boletín epidemiológico de la semana epidemiológica 46, del Ministerio de Salud de la Nación con requerimiento de cuidados intensivos. Se trata de un hombre de 44 años con síndrome de in munodeficiencia adquirida y viruela símica grave, que presentó insuficiencia ventilatoria obstructiva, por com promiso de vías aéreas y lesiones generalizadas extensas de tegumento, genitales y fauces. En conclusión, el caso presentado alerta sobre las potenciales complicaciones que pueden requerir cuidados críticos y poner en riesgo la vida del paciente.

Abstract Monkey pox is a rare zoonotic disease. It was first described in humans in Africa in 1970. On July 23, 2022, in view of the increasing number of cases reported in several countries and territories, the World Health Or ganization (WHO) concluded that the global outbreak constitutes a public health emergency of international concern. In our country, the first case was reported on May 22, 2022 and up to November 22 of this year, 895 patients were reported. We describe here the first case registered in Argentina requiring intensive care, accor ding to the Epidemiological Bulletin, 46th epidemio logical week, National Ministry of Health. The patient was a 44-year-old man with acquired immunodeficiency syndrome and severe Monkeypox, who presented obs tructive ventilatory failure due to airway compromise and extensive generalized lesions of the integument, genitalia and fauces. In conclusion, the case presented alerts about potential complications that may require critical care and risk the patient’s life.

ABSTRACT Introduction: Most patients with serious and progressive diseases such as HIV/AIDS face a variety of psychological challenges, which is why in this research we ask ourselves what is the psychological state of patients with the acquired immunodeficiency syndrome disease interned at the Institute of Tropical Medicine in the year 2022. Objective: To evaluate the psychological state of patients with acquired immunodeficiency syndrome, admitted to the Institute of Tropical Medicine in 2022. Methodology: Descriptive, prospective study of a mixed approach with a non-experimental design in which 100 patients with a diagnosis of HIV/AIDS admitted to the IMT in the period from January to July 2022 were included, finding the following most relevant results: 30 to 66% of the total were 44 years old, coming from Asunción (31%), and Central area (53%). Regarding the cognitive state, 61% were lucid, located in time and space, memory and attention were affected in 51% of the patients; affective state: fear or apprehension were the main stages, followed by worry and impotence. Analyzing the somatic state, it was seen that the rest was bad, as was the diet. In relation to the interpersonal state, 87% had family support, the behavioral state showed inconsistencies in coping with symptoms and adherence. Conclusion: Sociodemographic and psychosocial factors, the perception of social support, beliefs related to the disease, personality traits, social skills, coping styles, among others, may allow patients with HIV/AIDS to face the disease in order to achieve adaptation and well-being of your general health.

RESUMEN Introducción: La mayoría de los pacientes con enfermedades graves y progresivas como el VIH/SIDA se enfrentan a una variedad de desafíos psicológicos, es por eso que en esta investigación nos preguntamos cual es el estado psicológico de pacientes con la enfermedad del síndrome de inmunodeficiencia adquirida, internados en el Instituto de Medicina Tropical en el año 2022. Objetivo: Evaluar el estado psicológico de pacientes con la enfermedad del síndrome de inmunodeficiencia adquirida, internados en el Instituto de Medicina Tropical en el año 2022. Metodología: Estudio descriptivo, prospectivo de enfoque mixto con diseño no experimental en el que se incluyeron a 100 pacientes con diagnóstico de VIH/SIDA internados en el IMT en el periodo de enero a julio de 2022, encontrando los siguientes resultados: 30 a 44 años en el 66% del total, procedentes de Asunción (31%), y del área Central (53%). Con respecto al estado cognitivo el 61% estaba lúcido, ubicado en tiempo y espacio, la memoria y atención se ven afectadas en el 51% de los pacientes; estado afectivo: el miedo o temor fueron los estadíos principales, seguido de la preocupación e impotencia. Analizando el estado somático se vio que el descanso fue malo, al igual que la alimentación. En relación al estado interpersonal el 87% contaba con apoyo familiar, el estado conductual mostró incoherencias en cuanto al afrontamiento de los síntomas y la adherencia. Conclusión: Los factores sociodemográficos y psicosociales la percepción de apoyo social, las creencias relacionadas con la enfermedad, los rasgos de personalidad, las habilidades sociales, los estilos de afrontamiento, entre otras, pueden permitir a los pacientes con VIH/ SIDA afrontar la enfermedad para lograr la adaptación y el bienestar de su salud general

Resumen En este trabajo se reseña el libro Tras los rastros de un corpus seropositivo: VIH y sida en la poesída costarricense (1983-2017), de Ronald Campos López (2022). Primero, se expone su importancia para los estudios sobre la literatura «VIH-positiva» costarricense; además, se señala la relevancia de su tema, «olvidado» en el ámbito académico literario, y de los aportes teóricos que apoyan todo el trabajo de análisis. Luego, se ofrece una síntesis de algunos capítulos del libro de Campos López, donde se comentan las aproximaciones a los distintos poemas seleccionados por el autor. Finalmente, se concluye que el libro ofrece mucho material para la reflexión académica, pero también para la política, ya que el estudio de la literatura VIH-positiva implica también el análisis de los saberes que han construido la «enfermedad».

Abstract This paper reviews the book Tras los rastros de un corpus seropositivo: VIH y sida en la poesída costarricense (1983-2017), by Ronald Campos López (2022). First, its importance for the studies on Costa Rican HIV-positive literature is exposed; in addition, the relevance of its theme - ''forgotten” in the literary academic field- and of the theoretical contributions that support the analysis of Campos López are pointed out. Then, a synthesis of some chapters of the book is offered, where the approaches to the different poems selected by the author are commented. Finally, it is concluded that the book offers a lot of material for an academic, but also for a political reflection, since the study of HIV-positive literature also implies the analysis of the different kinds of knowledge that has built the ''disease”.

BACKGROUND: Community service occupational therapists may be especially vulnerable to experiencing burnout. This study sought to determine the levels of burnout experienced by this population and to investigate the relationship between reported burnout and various contextual, personal, and demographic factors METHODS: A quantitative, descriptive, cross-sectional survey design was used. The online questionnaire included contextual information of the participants and the Maslach Burnout Inventory. Data were analysed using Statistica 13.5. The effect of contextual, personal and demographic variables on burnout was tested using Kruskal-Wallis tests RESULTS: All community service occupational therapists were invited to participate in the study. A response rate of 31.92% was achieved (n=75). High levels of emotional exhaustion were reported by 55% (n=41) of participants. 'Strong' and 'adequate' support systems were associated to a greater sense of personal accomplishment (p=0.02) and 'minimal' social support was associated to increased emotional exhaustion (p=0.01). Dissatisfaction with supervision was associated to increased emotional exhaustion (p=0.017). Job satisfaction was associated to a greater sense of personal accomplishment (p=0.0002). Job dissatisfaction was associated to depersonalisation (p=0.047) and emotional exhaustion (p=0.006 CONCLUSION: Support systems, supervision and job satisfaction showed significant association to burnout. Interventions to address these factors, and research that further investigates the impact of contextual factors on burnout is recommended. This is imperative if South African occupational therapy is to take seriously its responsibility to the therapists responsible for taking services to populations with the greatest health needs Implications for practice • Opportunities for occupational therapists to develop professional resilience to prevent burnout should be offered across the lifelong learning continuum. • Strengthening supervision capacity and implementing mentoring and supervision strategies that provide mutual reward for both parties are needed. • The responsibility for promoting the vitality and job satisfaction of COSTs should be taken seriously by the Department of Health as CSOTs continue the vital work of taking rehabilitation to South Africa's populations with the greatest health needs.

ABSTRACT Histoplasmosis is caused by the dimorphic fungus Histoplasma capsulatum, which involves lymphatic tissue, lungs, liver, spleen, adrenal glands, kidneys, and skin. In recent years, it has emerged as an opportunistic disease, mainly in individuals with altered cellular immunity, as is the case of AIDS patients. About 70% of South American patients with histoplasmosis and AIDS have cutaneous or mucosal lesions. In Argentina and Paraguay, histoplasmosis is the most common systemic mycosis in individuals with HIV infection. We present the case of an patient diagnosed with systemic histoplasmosis whose only manifestation is a single skin lesion, confirmed by pathology and, fundamentally by culture, constituting an unusual clinic presentation.

RESUMEN La histoplasmosis es una enfermedad causada por el hongo dimorfo Histoplasma capsulatum, que involucra al tejido linfático, pulmones, hígado, bazo, glándulas suprarrenales, riñones y piel. En los últimos años ha emergido como una enfermedad oportunista, principalmente en aquellos individuos con inmunidad celular alterada, como es el caso de los pacientes con SIDA. Cerca de 70% de los pacientes sudamericanos con histoplasmosis y SIDA presenta lesiones cutáneas o mucosas. En Argentina y Paraguay, la histoplasmosis es la micosis sistémica más frecuente en individuos con infección por el VIH. Presentamos el caso de una paciente con diagnóstico de histoplasmosis sistémica cuya única manifestación es la lesión cutánea, confirmado con la anatomía patológica y, fundamentalmente, con el cultivo, constituyendo una presentación clínica inusual.

ABSTRACT Introduction: The human immunodeficiency virus (HIV) is the pathogen that causes human immunodeficiency syndrome (AIDS). Its importance lies in the fact that during the year 2020 in the world 37.6 million people lived with HIV, 1.5 million contracted the disease, and there is no vaccine to prevent their infection. Objective: To study the publications on the development of vaccines worldwide using bibliometric statistics on the subject of HIV and its progression in the last 20 years, emphasizing the period of the SARS-CoV-2 pandemic. Methods: A bibliometric statistical analysis was performed using the PubMed (Medline) database. For the qualitative analysis, the SCImago database was used. Results: An increase in publications was observed since 2001, reaching a maximum in 2016. Publications in first quartile journals were considered, with authors with a high H index, with important interactions between them. From 2017 to date, there has been a decrease in the number of articles published. With this method, it is not feasible, for now, to determine that the installation of the pandemic had a negative impact on the publication of articles on this topic. Conclusion: HIV should be established as a priority item in the scientific/medical area, this methodology offers ample possibilities to deepen and understand how science and its development are being approached, particularly in crucial issues such as vaccine research and the HIV.

RESUMEN Introducción: el virus de inmunodeficiencia humana (VIH) es el patógeno causante del síndrome de inmunodeficiencia humana (SIDA). Su importancia radica en que durante el año 2020 en el mundo 37,6 millones de personas vivían con VIH, y 1,5 millones contrajeron la enfermedad, no existe una vacuna para prevenir su infección. Objetivo: estudiar las publicaciones sobre el desarrollo de las vacunas a nivel mundial usando estadística bibliométrica en el tema VIH y su progresión en los últimos 20 años, haciendo énfasis en el periodo de la pandemia por SARS-CoV-2. Métodos: se realizó un análisis estadístico bibliométrico, usando la base de datos PubMed (Medline). Para el análisis cualitativo se utilizó la base SCImago. Resultados: se observó un aumento en las publicaciones desde el año 2001, alcanzando un máximo el año 2016. Se consideraron las publicaciones en revistas del primer cuartil, con autores(as) con elevado índice H, con importantes interacciones entre ellos. Desde el año 2017 a la fecha se observa una disminución en el número de artículos publicados. Con este método no es factible, por ahora, determinar que la instalación de la pandemia impacto negativamente en la publicación de artículos de dicho tema. Conclusión: el VIH debería instaurarse como un ítem prioritario en el área científica/médica, esta metodología ofrece amplias posibilidades para profundizar y comprender cómo se está abordando la ciencia y el desarrollo de esta, en particular en cuestión cruciales como es la investigación en vacunas y el VIH.
