The relationship between attitude of nurses toward the patient safety and missed nursing care: A predictive study.

BACKGROUND: Positive attitude of nurses toward patient safety can play a major role in increasing the quality of nursing care and reducing missed nursing care. This study was conducted to determine the relationship between the Attitude of Nurses Toward Patient Safety and missed nursing care. METHODS: This study was conducted in 2021 at the hospitals of Tabriz University of Medical Sciences (Iran). In the present study, 351 nurses were included in the study by using a stratified random sampling method. Data collection tools were demographic questionnaire, missed nursing care questionnaire, and patient safety attitudes questionnaire. Missed Nursing Care Questionnaire includes 24 items, such as patient movement, rotation, evaluation, training, discharge planning, medication prescription, scored on a 4-point Likert scale ranging from score 1 (I miss rarely), score 2 (I miss occasionally), score 3 (I miss usually), and score 4 (I miss always). The highest score is 96 and the lowest score is 24 on this scale. A higher score indicates a higher possibility of missed care. RESULTS: The mean total (standard deviation) of missed nursing care was 32.76 (7.13) (score range: 24-96) and the mean total score of nurses' patient safety attitudes was 53.19 (18.71) out of 100. Results of the present study showed that nurses' patient safety attitudes are at a moderate level and have a significant inverse relationship with the incidence of missed nursing care (P<0.001). CONCLUSION: According to the results and given the relationship between patient safety attitudes and missed nursing care, it is essential to use individual and organizational interventions to increase patient safety attitudes in various dimensions in nurses and consequently to reduce missed nursing care and improve the quality of healthcare.

A comparison between in vivo and ex vivo HR-MAS 1H MR spectra of a pediatric posterior fossa lesion.

The present case report was aimed at identifying the molecular profile characteristic of a primitive neuro-ectodermal tumor (PNET) in a 3-year-old child affected by a lesion localized in the cerebellar region. The histological diagnosis was medulloblastoma. In vivo single voxel 1H magnetic resonance spectroscopy (MRS) shows high specificity in detecting the main metabolic alterations in the primitive cerebellar lesion; a very high amount of the choline-containing compounds and very low level of creatine derivatives and N-acetylaspartate. Ex vivo high resolution magic angle spinning (HR-MAS) 1H magnetic resonance spectroscopy, performed at 9.4 Tesla on the neoplastic specimen collected during surgery, allows for the unambiguous identification of several metabolites giving a more in-depth evaluation of the metabolic pattern of the lesion. The ex vivo HR-MAS MR spectra show that the spectral detail is much higher than that obtained in vivo and that, for example, myo-inositol, taurine and phosphorylethanolamine contribute to the in vivo signal at 3.2 ppm, usually attributed to choline-containing compounds. In addition, the spectroscopic data appear to correlate with some morphological features of the medulloblastoma. Consequently, the present study shows that ex vivo HR-MAS 1H MRS is able to strongly improve the clinical possibility of in vivo MRS and can be used in conjunction with in vivo spectroscopy for clinical purposes.

Ataxia-telangiectasia: the pattern of cerebellar atrophy on MRI.

We describe MRI of the brain in 19 patients with ataxia-telangiectasia (AT) and correlate the appearances with the degree of neurologic deficit. We examined 10 male and nine female patients; 17 were aged between 2 and 12 years (mean 8 years) but a woman and her brother were 35 and 38 years old, and had a variant of AT. Ataxia was the first recognized sign of the disease in every patient. We detected the following patterns of cerebellar atrophy: in the youngest patient, aged 2 years, the study was normal; in the five next youngest patients 3-7 years of age, the lateral cerebellum and superior vermis showed the earliest changes of atrophy; and all but one of the other patients had moderate to marked diffuse atrophy of vermis and cerebellar hemispheres. There were 12 patients aged 9 years and above; one, who was normal, was 9 years old. The five patients who at the time of examination were unable to walk all had diffuse atrophy involving both vermis and cerebellar hemispheres.

Incidental intracranial hemorrhage after uncomplicated birth: MRI before and after neonatal heart surgery.

We investigated the prevalence of intracranial hemorrhage (ICH) before and after neonatal heart surgery. We carried out pre- and postoperative MRI looking for brain lesions in 24 full-term newborns with known congenital heart disease. They underwent heart surgery with cardiopulmonary bypass (CPB), usually with deep hypothermic circulatory arrest (DHCA). The first MRI was 1-22 days after birth. There were 21 children born after uncomplicated vaginal delivery and three delivered by cesarean section (CS). ICH was seen in 13 (62%) of the vaginal delivery group but in none of the CS group. We saw subdural bleeding along the inferior surface of the tentorium in 11 (52%) and supratentorially in six (29%) of the 21 children with ICH. Small hemorrhages were present in the choroid plexus in seven (33%), in the parenchyma in one (5%) and in the occipital horn in one (5%). There were 26 foci of bleeding in these 21 patients (1.2 per patient). None was judged by formal neurologic examination to be symptomatic from the hemorrhage. Follow-up MRI after cardiac surgery was obtained in 23 children, showing 37 foci of ICH (1.6 per patient), but all appeared asymptomatic. Postoperatively, ICH had increased in 10 children (43%), was unchanged in seven (30%) and was less extensive in six (26%).

Precision and accuracy of subjective time estimation in different memory disorders.

The aim of this study was to evaluate how different memory disorders affect subjective time durations. For this purpose we studied prospective time estimations in 4 amnesic (A) and in 15 Alzheimer's disease (AD) patients, and compared their performance with that of 5 matched young normal controls (YC) and 15 elderly subjects (EC). For the short-time durations we asked the subject to repeatedly reproduce a standard interval of 1 s. To test how subjects evaluated longer time durations, we choose a verbal estimation procedure. The subjects' task was to read either 5, 10, 20, or 40 digits appearing one at a time, while concurrently keeping the rhythm of 1 key press per second. At the end of each sequence, subjects had to judge the elapsed time from the beginning of the trial. Results showed that amnesics can correctly reproduce 1-s intervals. However, their accuracy of verbal estimates of longer durations was severely impaired. AD patients showed increased variability on repeated reproduction of 1-s intervals and were both inaccurate and imprecise in their verbal estimate of longer durations. Using the framework of the Scalar Timing Model, we conclude that amnesic patients exhibit a deficit in encoding and storing the current time for intervals that exceed their short-term memory range, while AD patients show a pattern of deficit that is explained by a more widespread involvement of both the clock, the memory, and the decisional mechanisms.
