RESUMEN
Background: The evaluation of geriatric care in the emergency departments is necessary to improve the quality of care. This study aimed to determine the status of geriatric nursing care from the perspective of nurses working in the emergency department of hospitals. Materials and Methods: This study was a cross-sectional research study. Through census sampling, 252 nurses working in the emergency departments of hospitals of Ardabil Province were selected. The status of elderly care was assessed using the Geriatric In-Hospital Nursing Care Questionnaire. Data were analyzed using independent and one-sample t-tests and analysis of variance. Results: The mean (GerINCQ) score of the participants [mean (SD): 237.30 (75.30)] was significantly higher than the criterion score (201) (p = 0.001). The scores of the sub-scales of perception of elderly care [mean (SD): 45.42 (7.53)], aging-sensitive care delivery [mean (SD): 41.55 (10.25)], professional responsibility [mean (SD): 39.62 (9.86)], and attitude toward caring for elderly [mean (SD): 56.14 (12.53)] were significantly higher than the standard score (p = 0.001). However, the score of performed intervention [mean (SD): 38.36 (8.42)] was significantly (p = 0.02) lower than the criterion score (39). The score of professional responsibility and attitude toward elderly care was higher in women than men, and this difference was statistically significant (p < 0.05). Conclusions: The results showed that aging-coordinated care delivery, professional responsibility, and attitudes and perceptions of nurses toward elderly care were satisfactory, but performed intervention was unfavorable. According to the results of this study, nursing service managers can improve the quality of elderly nursing care through appropriate policies, fixing the workforce shortage, and closely monitoring elderly care in the emergency departments.
RESUMEN
This article investigates the dynamic behavior of the micro-cantilever beam in a non-contact atomic force microscope based on classic and Strain Gradient continuum theories. Governing equation of the system is derived using Euler-Bernoulli and Strain Gradient theories as a nonlinear partial differential equation. Then, the equation is converted to a nonlinear ordinary differential equation using the Galerkin method, and the lumped model is derived. The effect of van der Waals repulsive term is investigated, and it is demonstrated that its repulsive term has no considerable effect on the dynamic of the system compared with its attractive term. The stability region of the system and the frequency response are computed and validated analytically and numerically. The obtained analytical equation is used for comparing the frequency response of the classic and Strain Gradient systems. It was observed that the classic theory predicts the nonlinear behavior of the system including softening for a specific dimension, while the dynamic behavior of the system is linear for the same dimensions from the Strain Gradient theory point of view. This difference probably roots in ignoring the size effect in submicron scales by the classic theory. HIGHLIGHTS: The influence of the repulsive term of van der Waals force on the dynamic behavior of micro-beam and this term is investigated. A general closed-form equation is derived for the stability region of AFM by an analytical approach. Effect of size on the stability region is investigated. The frequency response of the system is derived using the multiscale method (MSM) approach.
RESUMEN
Cystic echinococcosis (CE), caused by the larval stage of Echinococcus granulosus, presents an important medical and veterinary problem globally, including that in Iran. Different genotypes of E. granulosus have been reported from human isolates worldwide. This study identifies the genotype of the parasite responsible for human hydatidosis in three provinces of Iran using formalin-fixed paraffin-embedded tissue samples. In this study, 200 formalin-fixed paraffin-embedded tissue samples from human CE cases were collected from Alborz, Tehran, and Kerman provinces. Polymerase chain reaction amplification and sequencing of the partial mitochondrial cytochrome c oxidase subunit 1 gene were performed for genetic characterization of the samples. Phylogenetic analysis of the isolates from this study and reference sequences of different genotypes was done using a maximum likelihood method. In total, 54.4%, 0.8%, 1%, and 40.8% of the samples were identified as the G1, G2, G3, and G6 genotypes, respectively. The findings of the current study confirm the G1 genotype (sheep strain) to be the most prevalent genotype involved in human CE cases in Iran and indicates the high prevalence of the G6 genotype with a high infectivity for humans. Furthermore, this study illustrates the first documented human CE case in Iran infected with the G2 genotype.
