RESUMO

Semiconductor heterojunctions are an effective way to achieve efficient photocatalysts, as they can provide an adequate redox potential with visible light excitation. Several works have reported synergistic effects with nanoparticle semiconductor materials. The question is still open for thin film heterojunctions formed by stacked layers, as photocatalysis is considered a surface phenomenon. To investigate if the internal layer really affects or modifies the photocatalytic properties of the external material, we analyze the thin film heterojunction with ZnO and Bi2O3 semiconductors deposited by spray pyrolysis in two configurations: substrate/ZnO/Bi2O3 and substrate/Bi2O3/ZnO. Microstructural analysis was performed to verify the formation of the physical junction of the materials and discard new ternary phases. The photocatalytic activity was analyzed as a function of the thickness of the layers under blue light irradiation. We determined the conduction and valence bands positions, the carrier concentrations, mobilities, Fermi levels, etc. that allowed us to distinguish two reaction mechanisms depending on the configuration. There is a strong compromise between the order and thickness of the layers with the photocatalytic activity. The internal electric field produced in the interface defines the route of the photogenerated charges, and therefore the photocatalytic response. Thus, well-designed thin film heterojunctions can indeed improve the photocatalytic activity of the surface layer.

RESUMO

BACKGROUND: Ocular trauma is one of the most important causes of ocular morbidity and inadequate visual acuity in developed and developing countries. In some countries, eye trauma is the leading cause of monocular blindness. Studies conducted in developing countries like Colombia suggest that there is a lack of awareness of preventive measures. In Colombia, there is no countrywide ocular trauma registry. The purpose of the present study is to describe and analyse characteristics of ocular trauma at a tertiary ophthalmology emergency department in Colombia. PATIENTS/METHODS AND MATERIAL: Patients who consulted or were referred to the ophthalmologic emergency department of FOSCAL due to eye injuries between March 1, 2022, and January 10, 2023, were included in this cross-sectional study. RESULTS: Of 1 957 patients, 2 088 eyes were included. Men comprised 78.5% of the patients, the median age was 36 years, and 75.0% lived in urban areas. The median latency between trauma and ophthalmology consultation was 21.8 hours. Of the eyes, 1 805 (88.4%) had suffered mechanical or mixed (mechanical plus burn) trauma. Of the injuries, 87.5% were unilateral. In terms of the circumstances, 45.9% of injuries occurred during working or educational activities (in 85.6% of these cases, without eye protection), 28.2% in home accidents, and 14.0% in transportation situations. According to the Birmingham Eye Trauma Terminology System (BETT), 1 735 eyes (91.1%) were closed globe injuries, and 49 eyes (2.7%) were open globe injuries. Fifty eyes (2.8%) could not be categorised according to BETT at the initial consultation and were classified as "still to be determined". In the Ocular Trauma Score (OTS), 85.8% were category 5. Of the ocular burn cases, 93.0% were categorised as grade I according to the Roper Hall classification. CONCLUSIONS: In line with global literature, a much higher proportion of men than women sought consultation for ocular trauma. The findings suggest a need for improvement in the referral process from institutions with the lowest level of care. Lack of awareness about eye protection is an issue. Surgical exploration or additional tests may be necessary for precise injury classification. We therefore propose adding a "still to be determined" category to the BETT initial classification. These cases may be reclassified later, thus improving the accuracy of OTS calculation.

RESUMO

Purpose: The COVID-19 pandemic affected medical practice worldwide due to interventions to prevent spreading. Its effect on ophthalmology practices in Latin America has not yet been explored. We aimed to assess the perceptions about the pandemic from countries' ophthalmological national and subspecialty retina societies affiliated to the Pan-American Association of Ophthalmology (PAAO). Patients and Methods: A survey-based study of leaders of national ophthalmological and retinal societies was conducted. The survey was sent by email to 30 societies, from which 20 responded (12 countries, 66.6% response rate). It included closed- and open-ended questions about (1) operational capacity and precautions, (2) telemedicine and virtual care, (3) procedures, and (4) post-pandemic considerations. Results: There was a marked decline in ophthalmology patient visits (80-95%) and elective surgeries (90%) during 2020 compared to before the pandemic. Precautions like temperature checks, mask usage, and social distancing were widely implemented while personal protective equipment (PPE) availability varied. Telemedicine use was limited due to lack of experience with it. Reopening plans focused on maintaining precautions and gradually resuming activities. Economic and security concerns were raised, and adherence to guidelines was emphasized. Respondents acknowledged the need to adapt to a "new normal". Long duration drugs, fewer imaging studies, and shorter wait times were preferred; however, availability of long duration drugs was limited. Conclusion: The pandemic impacted ophthalmology in Latin America, with reduced patient visits, procedures, and surgeries. Delayed treatment and complications were likely the result of the pandemic.

RESUMO

Objetivo: Caracterizar el impacto de la pandemia por COVID-19 en las internaciones psiquiátricas en la región de América Latina y el Caribe. Métodos: Estudio descriptivo. Se realizaron 85 entrevistas semiestructuradas con trabajadores de hospitales generales (HG) y hospitales especializados (HE) en salud mental en 18 países de la región de América Latina y el Caribe entre el 8 de mayo y el 30 de junio de 2020. Los datos se analizaron cuantitativa y cualitativamente. Resultados: Se reporta una disminución inicial en la demanda de internación, atribuida al temor de la población a acercarse a los servicios, así como a restricciones en la movilidad. Se indican criterios más estrictos para internar con una doble focalización de lo agudo dentro de lo agudo. Los tiempos de internación presentaron un comportamiento mixto, tanto de aumento como de disminución en HG y en HE. La oferta terapéutica durante la internación se vio drásticamente reducida, y se restringió la interacción de las personas internadas con sus redes de apoyo. Conclusiones: La internación pareciera estar siendo no la última, sino la única alternativa de tratamiento psiquiátrico en el contexto de la pandemia. La reducción de camas en los HE podría ser un aspecto positivo para la reforma de la atención, pero es puesto en duda, ya que dicha reducción también se produce en los HG.

Objetive: To characterise the impact of the COVID-19 pandemic on psychiatric hospitalisations in the Latin American and Caribbean (LAC) region. Methods: Descriptive study. 85 semi-structured interviews were conducted with health workers involved with psychiatric hospitalizations in general hospitals (GHs) and specialised psychiatric hospitals (SHs) from 18 LAC countries. The interviews were done between 8 May and 30 June 2020. The data were analysed quantitatively and qualitatively. Results: An initial decrease in the demand for hospitalization is reported, attributed to the population's fear of approaching health services as well as restrictions on mobility. Stricter criteria for hospitalization were reported with a double focus on the acute within the acute. The length of hospitalizations were mixed, with both increases and decreases in GHs and SHs. The therapeutic offer was drastically reduced, and interaction between hospitalised people and their support networks was restricted. Conclusions: In the COVID-19 context, hospitalization seems to be not the last but the only alternative for psychiatric treatment. The decrease in the number of beds in SHs could be a positive aspect for the reform of psychiatric care, but it is questioned since this reduction also occurs in GHs.

RESUMO

Objectives: The personal impact of COVID-19 on mental health care workers (MHWs) has received scarce attention despite their work addressing the emotional wellbeing of those affected by the pandemic. This study aims to analyze Latin American and Caribbean's MHWs' subjective impact in connection to working during the initial times of the pandemic. Methods: One hundred and fifty-five persons (n = 155) from seventeen countries were contacted in May-June 2020 through a snowball approach. Complementary methodological strategies of analysis used for data triangulation included content analysis, thematic analysis, and interpretative phenomenological analysis. Results: Participants reported feelings of fear, anxiety, anguish, and fatigue. Milder negative impacts (e.g., uncertainty, concern), and complex feelings (e.g., ambivalence) were also frequent. One third of participants acknowledged their capacity to learn from this situation and/or experience satisfaction. Conclusion: Mental health of MHWs in Latin America and the Caribbean were under severe strain and the ongoing mental health reforms at risk during the pandemic's beginning. More research and additional care may be needed to offer support to those involved in caring for the wellbeing of others.

ABSTRACT INTRODUCTION The COVID-19 pandemic produced a reorganization of health systems and, in particular, affected the provision of services for people with psychosocial disabilities in a way that was pending an analysis in Argentina. The objective was to characterize the effects of the COVID-19 pandemic on services aimed at people with psychosocial disabilities in the cities of Rosario (Santa Fe), Resistencia (Chaco) and the Metropolitan Area of Buenos Aires from the perspective of their workers during 2020-2021 METHODS An exploratory and descriptive study was carried out by interviewing 53 workers from three types of rehabilitation services (aimed at providing support for socialization, for work or for housing) in two moments (November-December 2020 and April-June 2021). Frequencies were calculated and a thematic analysis was performed RESULTS The impact on services was broad and long-lasting, they became less accessible and effective in contributing to rehabilitation. Common aspects such as the new centrality of technology, massive adaptations and deep subjective impact on workers marked by fatigue were observed. Within a year of the pandemic, two-thirds of socialization-oriented services were still severely affected or closed DISCUSSION From the description and analysis of how the rehabilitation services were affected, the question remains regarding their future and how the mental health reform will unfold.

RESUMO

INTRODUCTION: The impact of the COVID-19 pandemic on health workers has been studied on an international level. However, mental health workers, who are also called upon to address such ailments both in the general population as well as in the health personnel, have not been asked about their experiences. METHODS: Seventy mental health workers in five regions of Argentina were interviewed between May and June 2020 regarding the subjective impact of changes in their work due to the pandemic. The responses were analyzed quantitatively and qualitatively. RESULTS: The results indicate emotions and experiences associated with a negative impact, in connection to feelings of tiresome, uncertainty, fear, anguish and anxiety and, to a lesser extent, some positive impacts are also described. More than a third of participants mentioned mixed feelings (i.e., being surprised, ambivalent, alert and sensitive). CONCLUSIONS: The personnel who are supposed to support the rest of the health workers are affected and experience having been relegated one more time to other aspects within the health care system. Focusing on learnings, having management roles, counting on colleagues, and agreeing with macro policies could be protective factors against the difficulties associated with the changes in work that the pandemic has imposed.

RESUMO

RESUMEN Se presenta un caso clínico de lipoma en lengua de un paciente masculino de 60 años de edad, masculino raza blanca, hipertenso y obeso. La lesión medía aproximadamente 2 centímetros de diámetro, comprometiendo cara dorsal de lengua a nivel de tercio anterior; es diagnosticado clínicamente y operado en el Hospital General Dr. Gustavo Aldereguía Lima de Cienfuegos. Se eliminó con buenos resultados la lesión; la cual aportó la novedad de su ubicación y forma. Se concluye que el diagnóstico oportuno y la eliminación por cirugía de este tipo de lesión es sumamente importante.

ABSTRACT Mesodermal origin tumors of the oral cavity and adjacent structures are an important part of stomatology due to the role that the oral cavity professional plays in the diagnosis and treatment of these lesions. Lipomas are benign neoplasms of adipose cells, extremely rare in the oral cavity. The buccal mucosa, tongue and floor of the mouth are some of the most common sites. The typical clinical presentation is that of an asymptomatic, yellow submucosal tumor lesion. Surgical removal is the treatment of choice, recurrence is rarely seen. A clinical case of lipoma on the tongue in a 60-years-old male patient is presented, which involves the dorsal aspect of the tongue at the level of the anterior third, diagnosed and treated at the Dr. Gustavo Aldereguia Lima General Hospital.

RESUMO

INTRODUCCIÓN: La pandemia por la enfermedad por el nuevo coronavirus (COVID-19) impactó en la organización y el funcionamiento del sistema de salud en su conjunto; aunque es muy poco lo descrito sobre lo ocurrido en los servicios de salud mental donde, además de atender la demanda habitual, se debe atender a la población afectada emocionalmente por la pandemia. El objetivo de este estudio fue caracterizar el efecto de la pandemia por COVID-19 en la provisión de servicios de salud mental en Argentina. MÉTODOS: Se realizó un estudio observacional transversal. Se entrevistó a 76 trabajadores de servicios de salud mental de cinco jurisdicciones del país, entre el 8 de mayo y el 30 de junio de 2020. Se indagó por cambios en la demanda, en el proceso de atención y en la estructura de los servicios. El análisis de datos fue mixto. RESULTADOS: La focalización de los servicios de salud en la pandemia implicó una reducción de la disponibilidad de atención en salud mental. La demanda de atención se modificó, con cambios en los motivos de contacto con los servicios, que pasaron a ser más críticos. Se observó una reconcentración de la atención en salud mental en los hospitales neuropsiquiátricos. La oferta de atención disminuyó y las intervenciones grupales se vieron especialmente afectadas. DISCUSIÓN: La situación de los servicios de salud mental muestra el impacto de la COVID-19 en el acceso de la población a la atención por necesidades no vinculadas de manera directa con la enfermedad.

RESUMO

A systematic review of the 25-year Mental Health production of Journal Ciência & Saúde Coletiva was performed to identify whether this production had changed over time. We investigated whether these changes would have any relationship with the implementation of a new regulatory and legal framework for this field and the expansion of public services and the promotion of public funding agencies' investigation on the subject. A total of 278 original papers were analyzed from the following categories: sociocultural transformations related to madness and its approach; legislative changes; implantation, coverage range and operation of the network of substitute services; clinic/care developed in substitute services; the role and possibilities of primary care; drug use-related problems; mental health of children and adolescents; epidemiological studies/psychiatric categories; and others - which included ethnic-racial issues, violence, about the elderly population, suicide, bullying, and migration. A chronological relationship can be observed between the increase in publications and research notices and the expansion of services, not seemingly in the same way concerning care for people with alcohol and other drug problems.

RESUMO

INTRODUCCIÓN La pandemia de COVID-19 y las medidas de distanciamiento social asociadas produjeron una reorganización de los sistemas de salud; específicamente, los servicios orientados a la atención de las personas con discapacidad psicosocial se modificaron y adaptaron en un tiempo breve. Este estudio provee un panorama de lo que fueron los efectos de la pandemia en los servicios que se dedican a brindar apoyo laboral, habitacional y a la socialización dirigidos a personas con discapacidad psicosocial. MÉTODO Se realizó un estudio exploratorio y descriptivo. Se entrevistaron de manera remota a 54 trabajadores en dos momentos diferentes de circulación comunitaria del virus. Se desarrolló en tres jurisdicciones de nuestro país; la ciudad de Rosario, provincia de Santa Fe; Resistencia, provincia de Chaco y el Área Metropolitana de Buenos Aires. El análisis fue mixto. Se calcularon frecuencias y se realizó un análisis temático para la comprensión de los aspectos más importantes transmitidos por los entrevistados. Se realizó rastreo bibliográfico para el armado del proyecto y el debate sobre los resultados. RESULTADOS Se observan diversos impactos en los dispositivos según el tipo de institución y el contexto. Una característica está relacionada con el grado de integración o articulación con los hospitales monovalentes, aquellos que funcionaban dentro del espacio físico o que su funcionamiento estaba asociado a las salas de internación, se vieron más afectados. En la mitad de los servicios indagados el funcionamiento en los primeros tres meses pasó a ser más restringido. Las dificultades para concretar ingresos a los dispositivos aumentaron. DISCUSIÓN Este tipo de servicios han sido particularmente afectados por el contexto del COVID19. Se destacan las potencialidades de los servicios con anclaje comunitario en el acompañamiento, el tejido de redes vinculares y la mejora de la calidad de vida de las personas con discapacidad psicosocial. Se abre el interrogante respecto al rumbo que tomará la reforma en salud mental y el modo en que estos servicios se verían afectados a largo plazo

RESUMO

INTRODUCTION: Central graft ulceration is a rare complication of an orbital dermal fat graft caused by diminished blood supply to the implant. This study reports on the efficacy and safety of the use of a single subconjunctival injection of autologous platelet-rich plasma to rescue an ulcerated orbital dermal fat graft. METHODS: Three patients, who had undergone autologous dermal fat graft to treat their anophthalmic socket, were given a 2-mL subconjunctival platelet-rich plasma injection in the exposed graft margins. Demographic and clinical features, treatment protocol, clinical course, complications and follow-up time are reported. In the preoperative examination, all the patients presented a primary epithelial defect of the dermal fat graft. RESULTS: There were no major complications such as necrosis or infection. One patient presented a small conjunctival granuloma at 1-month follow up. Mean postoperative follow-up duration was 13 (range: 10-16) months. By 1 month, the chronic epithelial defect had resolved with the graft integrated within the orbital tissues in all cases. All patients were referred for artificial prosthesis placement. CONCLUSION: Although further work is needed, our findings suggest that a single subconjunctival platelet-rich plasma injection could be an effective, safe and economic alternative to surgery to rescue an ulcerated orbital dermal fat graft.

RESUMO

The mental health users' movement is a worldwide phenomenon that seeks to resist disempowerment and marginalisation of people living with mental illness. The Latin American Collective Health movement sees the mental health users' movement as an opportunity for power redistribution and for autonomous participation. The present paper aims to analyze the users' movement in Argentina from a Collective Health perspective, by tracing the history of users' movement in the Country. A heterogeneous research team used a qualitative approach to study mental health users' associations in Argentina. The local impact of the Convention on the Rights of Persons with Disabilities and the regulations of Argentina's National Mental Health Law are taken as fundamental milestones. A strong tradition of social activism in Argentina ensured that the mental health care reforms included users' involvement. However, the resulting growth of users' associations after 2006, mainly to promote their participation through institutional channels, has not been followed by a more radical power distribution. Associations dedicated to the self-advocacy include a combination of actors with different motives. Despite the need for users to form alliances with other actors to gain ground, professional power struggles and the historical disempowerment of 'patients' stand as obstacles for users' autonomous participation.

Introduction. Several ophthalmological conditions are causes of consultations to the emergency services. The objective of this study was to determine the most common causes of consultation to the ophthalmological emergency service of a tertiary institution in Colombia and thus be able to explore in the future the possibility of identifying some preventive measures aimed at reducing the frequency of these causes. Methodology. Retrospective descriptive study based on the records of patients attending the emergency department during 2014 and 2015, identifying the diseases based on the International Classification of Diseases (ICD-10) codes. Results. 9,088 and 8,162 records were identified for 2014 and 2015, respectively. The most frequent causes of ophthalmologic urgency consultation for the year 2014 were: corneal or conjunctive foreign body with 20.2 %, acute conjunctivitis not specified 11.3 %, conjunctival trauma and corneal abrasion 8.3 %, conjunctival haemorrh age 5.8 % and corneal burns 4.7 %. In 2015 the causes were: foreign body in the cornea or conjunctiva (23.6 %), conjunctival trauma and corneal abrasion (9.0 %), acute unspecified conjunctivitis (8.9 %), conjunctival hemorrhage (4.4 %), and corneal burns (4.0 %). Discussion. The most frequent causes of consultation with ophthalmologic emergencies included trauma and infections of the anterior segment of the eye. Conclusions. There is a possibility of identifying some preventive measures (adequate protection elements, behavior protocols in situations of risk, etc.) that help to reduce the frequency of eye traumas and minimize the risk of infections. There is room for more studies in which the specific mechanisms of these injuries are analyzed. Cómo citar: Galvis V, Díaz AL, Ochoa ME, Rey JJ, Ardila LC, Olivero LP, Tello A.

RESUMO

Fusarium species are a group of fungi that cause superficial infections, locally invasive and disseminated disease, which occur mainly in immunocompromised hosts, and occasionally in immunocompetent individuals. We present three cases that show three different clinical forms of Fusarium spp. disease that affected different types of patients (patients with hematological malignancy, chronic kidney disease in peritoneal dialysis and post-surgical for osteoarticular pathology), each with its own characteristics that merit discussion. These cases show different clinical forms of invasive fusariosis caused by Fusarium solani complex species in patients with different pathologies and therapeutic management that could be risk factors for the development of the disease. The clinical recognition of fusariosis, not only in oncohematological patients, together with a timely diagnosis and treatment contribute to the success of the treatment and a reduction in mortality.

Las especies de Fusarium son un grupo de hongos que causan infecciones superficiales, localmente invasivas y enfermedad diseminada, que ocurren principalmente en huéspedes inmunocomprometidos, y ocasionalmente en individuos inmunocompetentes. Presentamos tres casos que ponen en manifiesto tres diferentes formas clínicas de la enfermedad por Fusarium spp., que afectaron diversos tipos de pacientes (pacientes con malignidad hematológica, enfermedad renal crónica en diálisis peritoneal y post-quirúrgico por patología osteoarticular), cada una con características propias que ameritan su discusión. Estos casos ponen de manifiesto diferentes formas clínicas de fusariosis invasiva causadas por especies del complejo Fusarium solani en pacientes con diferentes patologías y manejo terapéutico que podrían ser factores de riesgo para el desarrollo de la enfermedad. El reconocimiento clínico de la Fusariosis, no solo en pacientes oncohematólogicos, junto con un diagnóstico y tratamiento oportuno contribuyen al éxito del tratamiento y a una reducción en la mortalidad.

RESUMO

RESUMEN El pénfigo es una enfermedad autoinmune potencialmente mortal, que causa ampollas y erosiones en la piel y en la membrana mucosa. Las lesiones epiteliales son el resultado de autoanticuerpos que reaccionan con las glicoproteínas desmosomales y están presentes en la superficie celular del queratinocito. La reacción autoinmune contra estas glicoproteínas causa una pérdida de adhesión celular, resultando en la formación de ampollas intraepiteliales. Del 80 al 90 % de los pacientes con pénfigo vulgar, desarrollan trastornos cutáneos y en el 60 % de los casos alteraciones en la mucosa que es el primer o único signo. El diagnóstico de las lesiones en cavidad bucal es fundamental, ya que pueden prevenir su afectación a la piel. Si se establece el tratamiento en su etapa inicial, la enfermedad es más fácil de controlar y aumenta la posibilidad de una remisión temprana del trastorno y mejor calidad de vida. Este reporte de caso mostró a una paciente de 35 años, la que comenzó a presentar lesiones ulceradas en toda la orofaringe, con sensación de ardor e incapacidad para la ingestión de alimentos. El diagnóstico fue pénfigo vulgar (AU).

ABSTRACT Pemphigus is a potentially deadly autoimmune disease causing blisters and erosions in the skin and the mucous membrane. The epithelial lesions are the result of antibodies reacting to desmosomal glycoproteins, and are present in the keratinocytes cellular surface. The autoimmune reaction to these glycoproteins causes a cellular adhesion loss resulting in the formation of intraepithelial blisters. From 80 to 90 % of the patients with vulgar pemphigus develop skin disorders, and 60 % of the cases show mucosa changes as the first or unique sign. The diagnosis of the lesions in oral cavity is essential because it could prevent the skin damage. If the treatment begins in an initial stage, it is easier to control the disease and the possibility of the disorder's early remission and a better life quality increases. This is the report of the case of a female patient, aged 35 years, who presented ulcerated lesions in the entire oropharyngeal region, with itching sensation and inability for food consumption. The diagnosis was vulgar pemphigus (AU).

ABSTRACT Fusarium species are a group of fungi that cause superficial infections, locally invasive and disseminated disease, which occur mainly in immunocompromised hosts, and occasionally in immunocompetent individuals. We present three cases that show three different clinical forms of Fusarium spp. disease that affected different types of patients (patients with hematological malignancy, chronic kidney disease in peritoneal dialysis and post-surgical for osteoarticular pathology), each with its own characteristics that merit discussion. These cases show different clinical forms of invasive fusariosis caused by Fusarium solani complex species in patients with different pathologies and therapeutic management that could be risk factors for the development of the disease. The clinical recognition of fusariosis, not only in oncohematological patients, together with a timely diagnosis and treatment contribute to the success of the treatment and a reduction in mortality.
