PURPOSE: The aim of the study was to enhance the transdermal delivery of diclofenac potassium (DP) from hydrogels by constant voltage iontophoresis (CVI). The other objective was to establish the safety and efficacy of CVI in rats. METHODS: Hydrogels of DP were developed using hydroxyethyl cellulose as matrix material and geraniol, l-menthol and thymol as iontophoretic efficiency enhancers (IEE). In vitro permeation of hydrogels under CVI (1.5V) was performed in Franz diffusion cells across porcine skin...

BACKGROUND: One of the most difficult issues for care staff is the manifestation of challenging behaviour among residents with dementia. The first step in managing this type of behaviour is analysing its triggers. A structured assessment instrument can facilitate this process and may improve carers' management of the situation. This paper describes the development of an instrument designed for this purpose and an evaluation of its content validity and its feasibility and practicability in nursing homes...

The aim of this registry study was to compare products used to control symptoms of CVI. Endpoints of the study were microcirculation, effects on volume changes, and symptoms (analogue scale). Pycnogenol, venoruton, troxerutin, the complex diosmin-hesperidin, Antistax, Mirtoselect (bilberry), escin, and the combination Venoruton-Pycnogenol (VE-PY) were compared with compressions. No safety or tolerability problems were observed. At inclusion, measurements in the groups were comparable: 1,051 patients completed the registry...

BACKGROUND AND OBJECTIVES: Assessment of the nutrition care process (NCP) knowledge, attitudes, practices, and perceived barriers (KAPB) of dietetics practitioners is imperative before NCP is implemented completely in dietetics practice. No questionnaire assessing NCP KAPB has been developed and validated. Hence, we developed an NCP KAPB questionnaire called the KAPB-NCP and established its content validity. METHODS AND STUDY DESIGN: A total of 116 items associated with sociodemographic characteristics (7 items), professional development (3 items), organisational culture's support for the NCP (2 items), knowledge (27 items), attitudes (39 items), practices (20 items), and perceived barriers to implementing the NCP (14 items) were generated for potential inclusion in the KAPB-NCP questionnaire...

Choroid thinning occurs in age-related macular degeneration (AMD). However, it remains unclear whether the reduction is due to reduction in choroidal vessels or shrinkage of choroidal stroma, or both. The purpose of this study was to evaluate the changes of the choroidal vascular and stromal area in 118 patients with typical AMD (t-AMD) and polypoidal choroidal vasculopathy (PCV) over a 12-month period. We used spectral-domain optical coherence tomography (SD-OCT) with enhanced depth imaging (EDI) mode to measure the subfoveal choroidal thickness (CT), central retinal thickness (CRT) and choroidal vascularity index (CVI - ratio of luminal area to total choroidal area)...

OBJECTIVES: The study aimed to test and compare the reliability and validity, including sensitivity and specificity of the two self-care-related instruments, the Self-care Ability Scale for the Elderly (SASE), and the Appraisal of Self-care Agency Scale-Revised (ASAS-R), among older adults in the Chinese context. METHODS: A cross-sectional design was used to conduct this study. The sample consisted of 1152 older adults. Data were collected by a questionnaire including the Chinese version of SASE (SASE-CHI), the Chinese version of ASAS-R (ASAS-R-CHI) and the Exercise of Self-Care Agency scale (ESCA)...

AIM: Handover, in particular between two shifts, is a crucial aspect of nursing for patient safety, aimed at ensuring continuity of care. During this process, several factors can affect quality of care and cause errors. This study aimed to assess quality of handovers, by validating the Handoff CEX-Italian scale. METHOD: The scale was translated from English into Italian and the content validity index was calculated and internal consistency assessed. The scale was used in several units of the San Paolo Teaching Hospital in Milan, Italy...

BACKGROUND AND PURPOSE: The purpose of this study was to develop a reliable and valid measure of faculty response patterns to the needs of underrepresented minority (URM) nursing students. METHODS: A mixed-method approach. RESULTS: The 10-item scale was found to be valid (content validity index [CVI] = .81) and reliable (Cronbach's alpha = .81). Principle component factor analysis with varimax rotation yielded a 3-factor solution that explained 66% of the variance in faculty engagement with URM students...

The evolution of the thermal conductivities of the unidirectional, 2D woven and 3D braided composites during the CVI (chemical vapor infiltration) process have been numerically studied by the finite element method. The results show that the dual-scale pores play an important role in the thermal conduction of the CVI-densified composites. According to our results, two thermal conductivity models applicable for CVI process have been developed. The sensitivity analysis demonstrates the parameter with the most influence on the CVI-densified composites' thermal conductivity is matrix cracking's density, followed by volume fraction of the bundle and thermal conductance of the matrix cracks, finally by micro-porosity inside the bundles and macro-porosity between the bundles...

SiBCN ceramics were introduced into porous Si₃N₄ ceramics via a low-pressure chemical vapor deposition and infiltration (LPCVD/CVI) technique, and then the composite ceramics were heat-treated from 1400 °C to 1700 °C in a N₂ atmosphere. The effects of annealing temperatures on microstructure, phase evolution, dielectric properties of SiBCN ceramics were investigated. The results revealed that α-Si₃N₄ and free carbon were separated below 1700 °C, and then SiC grains formed in the SiBCN ceramic matrix after annealing at 1700 °C through a phase-reaction between free carbon and α-Si₃N₄...

A comprehensive fall risk assessment can provide information for effective prevention and intervention measures and reduce falls among hospitalized elderly people. The purpose of this study was to develop a Chinese version of an inpatient fall risk assessment tool and evaluate its validity and reliability.This study employed the Falls Risk for Hospitalised Older People (FRHOP) assessment to construct a FRHOP-Taiwan Version (Tw-FRHOP) through forward, synthesized, and backward translation. A face validation was conducted by 5 clinical nurses and a content validation was conducted by 5 specialists using the content validity index (CVI) to validate the proposed model...

OBJECTIVE: High-performance marine craft personnel (HPMCP) are regularly exposed to vibration and repeated shock (VRS) levels exceeding maximum limitations stated by international legislation. Whereas such exposure reportedly is detrimental to health and performance, the epidemiological data necessary to link these adverse effects causally to VRS are not available in the scientific literature, and no suitable tools for acquiring such data exist. This study therefore constructed a questionnaire for longitudinal investigations in HPMCP...

BACKGROUND: Recent studies showed that some cell population data (CPD) parameters of neutrophils may be useful for diagnosing myelodysplastic syndromes and sepsis, for the differential diagnosis of acute promyelocytic leukemia, and some CPD parameters of lymphocytes may be a valuable tool for preliminary screening of B cell lymphoproliferative disease. Notwithstanding the knowledge, no information has been made available about their analytical quality specification. This study was aimed to define short- and medium-term biological variation (BV) estimates and reference change value (RCV) of leukocyte count, extended leukocyte differential and CPD...
