RESUMO

Nitrile gloves have become a significant environmental pollutant after the COVID-19 pandemic due to their single-use design. This study examines the capability of P. aeruginosa to use nitrile gloves as its sole carbon energy source. Biodegradation was determined by P. aeruginosa adapting to increasing nitrile glove concentrations at 1%, 3%, and 5% (w/v). The growth kinetics of P. aeruginosa were evaluated, as well as the polymer weight loss. Topographic changes on the glove surfaces were examined using SEM, and FT-IR was used to evaluate the biodegradation products of the nitrile gloves. Following the establishment of a biofilm on the glove surface, the nitrile toxicity was minimized via biodegradation. The result of the average weight loss of nitrile gloves was 2.25%. FT-IR analysis revealed the presence of aldehydes and aliphatic amines associated with biodegradation. SEM showed P. aeruginosa immersed in the EPS matrix, causing the formation of cracks, scales, protrusions, and the presence of semi-spherical particles. We conclude that P. aeruginosa has the capability to use nitrile gloves as its sole carbon source, even up to 5%, through biofilm formation, demonstrating the potential of P. aeruginosa for the degradation of nitrile gloves.

RESUMO

PURPOSE: To estimate the prevalence and demographic characteristics of uncorrected refractive errors (URE) in people who attended eye care consultations in Colombia between 2015 and 2019, using the National Health Registry data. METHODS: We identified ICD codes for myopia (H-52.1), degenerative myopia (H-44.2), hyperopia (H-52.0), and astigmatism (H-52.2) from the Integrated Social Protection Information System. Crude prevalence rates by age and sex were calculated for the population attending eye care services during these years. Additionally, we developed a standardized morbidity map across county departments. RESULTS: In Colombia, the prevalence of URE among eye care consultations was 30.26%, increasing from 30.39% in 2015 to 35.14% in 2019. Of the 1,579,778 cases analyzed, 60.9% were females. Astigmatism emerged as the most prevalent URE, predominantly seen in individuals under 40 years old. Myopia showed the highest prevalence in the 10-30 age group, whereas hyperopia was most prevalent in the first decade of life. Geographically, the Andean region recorded most of URE cases, while more remote areas have seen a rising morbidity risk in recent years. CONCLUSIONS: The rising trend of URE in Colombia and its demographic and geographical variations underscores the urgent need for health professionals and government authorities to acknowledge and address this issue. This study provides crucial insights into the refractive error landscape across the country, highlighting the necessity for prevention programs specifically designed to cater to the country's unique needs.

RESUMO

This scoping review examined the relationship between Dry Eye Disease (DED) and Uveitis. We searched Pubmed, Embase, and LILACS databases for articles in which at least one patient had DED and uveitis concomitantly. The search produced 2381 records, and 24 studies were included in the qualitative synthesis. We concluded that DED and uveitis of any etiology could appear concomitantly in patients of any age. However, both diseases seem to coexist more frequently in middle-aged women and cases of anterior uveitis. Therefore, it is crucial that ophthalmologists actively look for the coexistence of ocular surface abnormalities, especially in patients with these characteristics. Future studies should establish and quantify the risk factors and pathophysiological mechanisms of this coexistence to achieve an early diagnosis of both etiologies and comprehensive management of these patients.

RESUMO

Objective: To contextualize a synthesis of evidence on interventions in student mental health during the COVID-19 pandemic through a deliberative dialogue with Ibero-American universities. Methods: An evidence synthesis and synchronous dialogues were previously conducted, consisting of subgroup discussions about the design and implementation of mental health interventions. An analysis of dialogic data was conducted, then organized by topic. Results: Fifty-seven representatives of 17 public and private Ibero-American universities participated in the meeting. In terms of the design of interventions, mental health is perceived as neglected, although its profile was raised by the pandemic. Interventions are guided by detection of needs; scientific evidence is rarely used to design them. Importance was given to forming an interdisciplinary team with continuous training in order to design a specific program that also covers families and teaching/administrative staff. In terms of implementation, problems include saturation of services due to high demand and lack of basic resources among students. Regarding the provision of resources, the influence of the broader context, including the institutional context, is undeniable. The dialogues were perceived as an opportunity to build a new set of interventions. Conclusions: These dialogues enriched the description of interventions already described in the literature on student mental health during the COVID-19 pandemic. However, implementing such interventions in the region means addressing previous neglect and a high level of unmet basic needs.


Objetivo: Contextualizar uma síntese de evidências sobre intervenções em saúde mental de estudantes universitários na pandemia de COVID-19, por meio do diálogo deliberativo com universidades ibero-americanas. Métodos: A partir de uma síntese de evidências previamente elaborada, o diálogo síncrono foi conduzido por meio de discussões em subgrupos sobre o planejamento e a implementação de intervenções em saúde mental. Os dados obtidos foram analisados e resumidos por área temática. Resultados: Cinquenta e sete integrantes de 17 universidades ibero-americanas públicas e privadas participaram do encontro. Os participantes indicaram que a saúde mental é negligenciada no planejamento das intervenções, mas ganhou visibilidade na pandemia. As intervenções são direcionadas às necessidades identificadas e raramente planejadas com base em evidências científicas. Disseram considerar importante formar uma equipe interdisciplinar com capacitação contínua para planejar um programa específico que englobe também familiares e o corpo docente e administrativo. Implementar intervenções é complicado porque os serviços estão sobrecarregados devido à grande demanda e à falta de recursos básicos para os estudantes. O contexto macro e institucional claramente influencia a disponibilização de recursos. O diálogo foi visto como uma oportunidade para consolidar um novo conjunto de intervenções. Conclusões: O presente diálogo contribuiu para enriquecer a literatura de intervenções de saúde mental para estudantes universitários na pandemia de COVID-19. Implementar intervenções no nosso contexto requer sanar as falhas por negligência passada e as enormes necessidades básicas não atendidas.

RESUMO

[RESUMEN]. Objetivo. Contextualizar una síntesis de evidencia sobre intervenciones en salud mental estudiantil durante la pandemia de la enfermedad por el coronavirus 2019 (COVID-19, por su sigla en inglés) por medio de un diálogo deliberativo con universidades iberoamericanas. Métodos. Se realizó previamente una síntesis de evidencia y un diálogo sincrónico, que consistió en la discusión en subgrupos acerca del diseño y aplicación de las intervenciones en salud mental. Se realizó un análisis de datos dialógicos y se sintetizó por temas. Resultados. Cincuenta y siete miembros de 17 universidades iberoamericanas públicas y privadas participaron en el encuentro. En el diseño de las intervenciones, se percibe la salud mental como desatendida, y visibilizada con la pandemia. La detección de necesidades es la que orienta las intervenciones y rara vez se utiliza evidencia científica para diseñarlas. Se considera importante conformar un equipo interdisciplinario con capacitación continua para diseñar un programa específico, que cubra también familias y personal docente y administrativo. En la aplicación, existen problemas como la saturación de los servicios por la alta demanda y la falta de recursos básicos de los estudiantes. Es innegable la influencia del contexto macro e institucional por la disposición de recursos. El diálogo fue percibido como oportunidad para construir un consolidado nuevo de intervenciones. Conclusiones. Este diálogo permitió enriquecer la descripción de intervenciones en salud mental estudiantil durante la pandemia de COVID-19 ya descritas en la literatura, aunque llevarlas a la práctica en nuestro contexto supone hacer frente a la deuda por la desatención previa y las altas necesidades básicas insatisfechas.

RESUMO

Colombia is one of the major producers and exporters of banana Musa paradisiaca. Its consumption is high then its agro-industrial wastes are important source to extract pectin. In the present study, inorganic acids (nitric acid and hydrochloride acid) and organic acids (citric acid and acetic acid) were evaluated to extract pectin from banana peels at pH 2 and 3, through acid hydrolysis during 1h at the temperature of 85 °C. The extraction yield, degree of esterification (DE) and intrinsic viscosity of the pectin were characterized. Nitric acid (NA) allowed to obtain higher extraction yield (54 ± 10%) and citric acid (CA) allowed to obtain higher DE (76.7 ± 2%). Additionally, the effect of polymer concentration and degree esterification, low degree of esterification (LDE, 33.1%) and high degree of esterification (HDE, 76.7%) were evaluated in the pectin nanoparticles formation. The pectin with HDE formed stable nanoparticles with a particle size of 255 ± 11 nm and the zeta potential value of -45 ± 3 mV, independently of the polymer concentration. Morphology analysis showed aggregated of the pectin nanoparticles.

RESUMO

Introducción Las fracturas de la diáfisis del húmero son frecuentes, con distribución bimodal en la población. El manejo no quirúrgico con inmovilización y brace funcional es considerado como el estándar de oro con algunas complicaciones determinadas que pueden ocurrir de forma temprana o tardía durante el tratamiento. El atrapamiento del nervio radial por el callo óseo con afectación neurológica es un evento raro publicado en la literatura. Materiales y métodos Se describen dos casos de neuroapraxia tardía del nervio radial en pacientes que sufrieron fracturas de trazos simples quienes cumplían criterios para tratamiento no quirúrgico. Se realizó una revisión narrativa de la literatura en bases de datos conocidas buscando casos similares para optimizar el manejo médico. Resultados Se presentan los desenlaces clínicos de los dos casos que fueron intervenidos quirúrgicamente por el mismo cirujano y que compartían los mismos diagnósticos de atrapamiento del nervio radial por callo óseo durante tratamiento inicial no quirúrgico. Se reportan los resultados de la revisión narrativa de la literatura. Discusión La neuroapraxia del nervio radial por atrapamiento en callo óseo en los primeros días de un tratamiento no quirúrgico para fracturas de trazos simples en diáfisis de húmero es una complicación rara pero posible que confirma la necesidad de una vigilancia estricta del paciente y de aclarar dicho evento.


Background Fractures of the shaft of the humerus are frequent, with bimodal distribution in the population. Non-surgical management with immobilization and a functional brace is considered the gold standard with some specific complications that can occur early or late during treatment. The entrapment of the radial nerve by the bone callus with neurological involvement is a rare event reported in literature. Methods Two cases of late radial nerve neuropraxia are described in patients who suffered simple line fractures who met criteria for nonsurgical treatment. A narrative review of the literature in known databases was carried out looking for similar cases to optimize medical management. Results The clinical outcomes of the two cases that underwent surgery by the same surgeon and that shared the same diagnoses of radial nerve entrapment due to bone callus during initial non-surgical treatment are presented. The results of the narrative review of the literature are reported. Discussion Neuropraxia of the radial nerve due to entrapment in bone callus in the first days of a non-surgical treatment for fractures of simple lines in the diaphysis of the humerus is a rare but possible complication that confirms the need for strict monitoring of the patient.

RESUMO

BACKGROUND: The choice of chemotherapy in HER2-negative gastric cancer is based on centre's preferences and adverse effects profile. No schedule is currently accepted as standard, nor are there any factors to predict response, other than HER2 status. We seek to evaluate whether Lauren type influences the efficacy of various chemotherapies and on patient overall survival (OS). METHODS: We have conducted a multicenter study in 31 hospitals. The eligibility criteria include diagnosis of stomach or gastroesophageal junction adenocarcinoma, HER2 negativity, and chemotherapy containing 2-3 drugs. Cox proportional hazards regression adjusted for confounding factors, with tests of 'treatment-by-histology' interaction, was used to estimate treatment effect. RESULTS: Our registry contains 1303 tumours analysable for OS end points and 730 evaluable for overall response rate (ORR). A decrease in ORR was detected in the presence of a diffuse component: odds ratio 0.719 (95% confidence interval (CI), 0.525-0.987), P=0.039. Anthracycline- or docetaxel-containing schedules increased ORR only in the intestinal type. The diffuse type displayed increased mortality with hazard ratio (HR) of 1.201 (95% CI, 1.054-1.368), P=0.0056. Patients receiving chemotherapy with docetaxel exhibited increased OS limited to the intestinal type: HR 0.65 (95% CI, 0.49-0.87), P=0.024, with no increment in OS for the subset having a diffuse component. With respect to progression-free survival (PFS), a significant interaction was seen in the effect of docetaxel-containing schedules, with better PFS limited to the intestinal type subgroup, in the comparison against any other schedule: HR 0.65 (95% CI, 0.50-0.85), P=0.015, and against anthracycline-based regimens: HR 0.64 (95% CI, 0.46-0.88), P=0.046. CONCLUSIONS: As a conclusion, in this registry, Lauren classification tumour subtypes predicted survival and responded differently to chemotherapy. Future clinical trials should stratify effect estimations based on histology.
