Necesidades humanas básicas en gestantes con alto riesgo obstétrico analizado bajo la Teoría de Wanda Horta

Objetivo: identificar las necesidades humanas básicas de las embarazadas de alto riesgo hospitalizadas con base en la Teoría de Wanda Horta. Método: investigación asistencial realizada con dieciséis gestantes de alto riesgo hospitalizadas en una maternidad de referencia en Ceará entre septiembre y noviembre de 2019. Se recolectó información a través de diario de campo y ficha de caracterización de las gestantes y registros de necesidades humanas básicas. Los resultados se analizaron mediante estadística descriptiva simple y un enfoque integral a la luz del marco de Wanda Horta. Resultados: las gestantes presentaron necesidades psicobiológicas, psicosociales y psicoespirituales, siendo prevalentes: ausencia de actividades de ocio, inseguridad emocional, escaso conocimiento, sueño y descanso perjudicados, y actividades físicas restringidas por indicación de descanso. Consideraciones finales: se cree que el razonamiento crítico y el juicio clínico de los enfermeros se centraron en la individualidad de las gestantes, identificando necesidades en los tres niveles propuestos por la teoría, apuntando caminos para cualificar el cuidado de enfermería a las gestantes de alto riesgo.

A simple dissection method for the isolation of mouse trabecular meshwork cells

by Maximilian Binter, Fridolin Langer, Xiaonan Hu, Migle Lindziute, Carsten Framme, Jan Tode, Heiko Fuchs

The outflow pathway, especially trabecular meshwork (TM), plays an essential role in glaucoma, and the availability of TM cells is crucial for in vitro research. So far, the isolation of TM cells from mice has been anything but manageable due to the small size of the eye. Direct isolation using a stereomicroscope and forceps requires a high grade of dexterity. Indirect isolation is based on the phagocytic properties of TM cells and involves injecting magnetic microspheres into the anterior chamber of live mice followed by isolation. Therefore, a simpler, less expensive, and nonexperimental strategy for isolating mouse TM cells would be desirable.

After enucleation, the eyes were cut in half anterior-to-posteriorly. The lens and posterior segment were removed. Iris and the attached ciliary body were gently pulled backward and disconnected from the remaining tissue to expose the TM. By incising through the cornea anteriorly and posteriorly of the TM, the cornea/TM stripe could be isolated. The cornea/TM stripe was cultured with the pigmented side down in a 6-well. The outgrowing pigmented cells were analyzed by immunocytochemistry and mRNA expression for previously described TM cell markers. The phagocytic properties of the cells were additionally confirmed using fluorescent microspheres.

Pigmented phagocytic cells were the first to grow out of the cornea/TM strips after approximately 4–7 days. Cells were positive for Collagen IV, Fibronectin1, Vimentin, and Actin alpha 2 and could phagocytize fluorescent microbeads. Cross-linked actin networks were visible after 9 days of exposure to TGFB2 (transforming growth factor-beta 2). Additionally, treatment with 500 nM Dexamethasone for one week increased myocilin expression, as previously reported for TM cells. In addition, we proved that this method can also be used in albino mice, which lack pigmentation of the trabecular meshwork.

The isolated cells show phagocytic properties and specific expression of markers reported in TM cells. Therefore, our dissection-based method is inexpensive and reproducible for isolating TM cells in mice.

Analysis of risk factors of infection in diabetic foot patients

Abstract

This cross-sectional study assessed the risk factors for infection in 150 diabetic foot patients admitted to the Xiamen University Hospital between October 2020 and October 2022. Patients were categorised as infected (n = 80) or uninfected (n = 70) cohorts. The diabetic foot was evaluated using the American Diabetic Foot Grading system, whereas ulcers were categorised using Wagner's method. Analysed were patient-specific information, clinical data and risk factors including neuropathy, arterial disease and foot deformities. Our findings revealed no statistically significant differences between infected and uninfected cohorts concerning age, body mass index, gender, duration of diabetes or ankle-brachial index values (p > 0.05). However, infected group had a higher proportion of smokers and reduced socio-economic status (p < 0.05). Wagner grades indicated a greater severity in the infected group, with grade 3, grade 4 and grade 5 differing significantly (p < 0.05). Comparative analysis of ulcer characteristics revealed no statistically significant differences in ulcer surface area and depth, but the infected group had a higher prevalence of osteomyelitis and a greater number of ulcers (p > 0.05). Blood vessel complications, retinopathy, the presence of three or more ulcers, osteomyelitis and diabetic nephropathy were substantially more prevalent in the infected group, as determined by univariate analysis (p < 0.05). Subsequent multivariate logistic analysis revealed that patients with blood vessel complications, retinopathy, osteomyelitis, diabetic nephropathy and three or more ulcers were at increased risk for infection (p < 0.05). In addition, lifestyle factors, such as smoking, sedentary behaviour, inadequate foot hygiene, obesity and poor glycaemic control, were also associated with higher infection rates. A multivariate analysis of foot wound factors revealed that deeper, longer and recurrent lesions increased the likelihood of infection. Escherichia coli was the most frequently isolated bacterium from the infected group's bacterial culture, followed by Pseudomonas aeruginosa and Staphylococcus aureus. The study enhanced our comprehension of the multifactorial risk factors associated with infections in diabetic foot patients, highlighting the need for thorough clinical evaluation, lifestyle modification and vigilant infection control.

Proceso de enfermería en la asistencia a pacientes en terapia de hemodiálisis

Objetivo: identificar los diagnósticos de enfermería y las intervenciones más frecuentes en la asistencia a los pacientes en hemodiálisis. Método: se realizó un estudio descriptivo, transversal, retrospectivo con un enfoque cuantitativo, realizado con 175 prontuarios de pacientes en hemodiálisis, asistidos en el servicio por un período de seis meses. Para la recolección de los datos, se utilizó la plataforma Google Forms®, generando una hoja de trabajo en Microsoft Excel®, un software que permite organizar, describir y analizar los mismos. Resultados principales: se identificaron tres diagnósticos de enfermería como más frecuentes: Riesgo de sangrado (67,2%); Riesgo de caída (56,5%) y Exceso de volumen de líquido (54,8%), en más de la mitad de los pacientes de acuerdo con los registros en los prontuarios. Las intervenciones de enfermería están dirigidas por el protocolo del procedimiento de hemodiálisis y no por los diagnósticos de enfermería. Conclusión: los diagnósticos más frecuentes se centran en las condiciones clínicas de la población estudiada, y no subvencionan las intervenciones de enfermería, que se definen con base en técnica de hemodiálisis.
