Executive and compensatory memory retraining in traumatic brain injury

A controlled treatment outcome study was conducted comparing the efficacy of memory remediation treatment with no treatment on traumatic brain-injury patients. The memory remediation treatment consisted of both compensatory and executive training skills and was delivered 6 hours weekly over a 2 1/2-week period. Six subjects in the treatment group and 6 subjects in the control group were matched on WAIS-R FSIQ scores, pre-test memory scores and age. Pre-and post-test measures were obtained for both groups on a paragraph memory task. A significant difference was demonstrated between the treatment and control post-test memory scores. The experimental group significantly improved memory scores beyond that of the control group, suggesting that memory remediation is effective for head-injury patients with memory deficits. Discussion of findings and suggestions for further investigation are presented.     

Natural killer cell activity and CSF monoamine metabolites in suicide attempters

The aim of this study was to investigate markers of serotonin and immune function in suicidal patients. Cytotoxic activity of natural killer cells (NK) and CD16 lymphocytes were studied in 28 suicide attempters and 26 healthy controls, and related in patients to 5-hydroxyindoleacetic acid (5-HIAA) in cerebrospinal fluid (CSF). Patients with CSF 5-HIAA below the median had significantly lower NK cell activity than other patients. CD16 cell frequency was significantly lower in patients than in controls, and patients also tended to have lower NK cell cytotoxicity than healthy controls. There were no statistically significant correlations between 4-hydroxy-3methoxyphenyl glycol (HMPG), homovanillic acid (HVA), CSF cortisol and NK cell activity. The results support the hypothesis of compromised immune function in suicidal patients with evidence of disordered serotonin function.     

Breastfeeding Preterm Twins: A Case Report

ABSTRACT: This case report describes a primipara who successfully breastfed 35-week-gestation twins for over six months. Positive interactions, research-based management strategies, and innovative problem solving helped her avoid the individual, interpersonal, and system factors that can injuence lactation failure.

Skin to skin contact in neonatal care: knowledge and expectations of health professionals in 2 neonatal intensive care units]

Skin to skin contact is a method derived from kangaroo care whose implementation in industrialized countries has rarely been assessed. OBJECTIVES: To evaluate the barriers, knowledge and expectations of health professionals regarding this care in 2 level III neonatal care units in the Nord-Pas-de-Calais. MATERIALS AND METHODS: Investigation was conducted by means of 2 questionnaires, one intended to physicians, the other to the nursing staff sharing some common questions. The 2 neonatal units differed by the level of implementation of skin to skin contact. Results were compared according to occupation and site of work. RESULTS: 80% of the physicians and 71.4% of the paramedical staff answered to the questionnaires. The difficulties were linked to technical or architectural constraints. Responses were not very different between the 2 teams. The majority (90%) considered this practice as a fully-fledged care. The positive effects on attachment (96% of the answers) were well-known but those on sleep (2,9%), breast-feeding (5%) and pain (0%) were only rarely mentioned. Barriers to implementation were centred on infant's safety. The majority of the team wished to benefit from an educational intervention. DISCUSSION: Although the perception of skin to skin contact was positive in these 2 teams, increased knowledge of the evidence supporting its practice could enable babies and parents to benefit from all its positive effects. The need for educational program was clearly mentioned to improve parents' information. CONCLUSION: This work emphasises the complexity of introducing new procedures in neonatal care particularly in the field of developmental care.     

Invasive ventilation in the emergency department: Part 2: Implications for patient safety

The use of mechanical ventilation in the Emergency Department requires adequate resources in order to maintain patient safety and avoid potential risks. Moreover, developments in technology require increased knowledge of mechanical ventilation techniques to address the complexity of decision-making involved. Organisational issues and system factors have the potential to negatively impact on the ability of the emergency service to provide optimum care to patients receiving mechanical ventilation. These issues include staffing and skill-mix, demand on emergency services, role-delineation, scope of practice, and current mechanisms for monitoring of quality and safety. Furthermore, in response to advances in ventilator technology, current education programs for both nursing and medical staff require review to ensure that they provide comprehensive information about the types of ventilation techniques now available and the relative risks and benefits associated with their application.This article is the second in a two-part series and explores the educational and organisational factors that impact upon safety and quality of care delivered to patients receiving mechanical ventilation in the emergency department. Recommendations for future policy development, curriculum review and reporting mechanisms to support further research in the application of mechanical ventilation in the emergency department are made.     

Radiographic assessment of instability of the knee due to rupture of the anterior cruciate ligament. A quadriceps-contraction technique

We compared the results of a radiographic technique for the measurement of instability of the knee with those obtained with a KT-1000 arthrometer. The study was conducted on both knees of sixty patients who had a ruptured anterior-cruciate ligament in one knee, as well as in ten control subjects. The radiographic technique included the examination of a true lateral radiograph, made while the knee was in full extension and the quadriceps was maximally contracted, with a 66.7-newton downward force produced by a 6.8-kilogram weight suspended from the ankle. As demonstrated by both techniques, the maximum difference between the displacements of the right and left knees in the control subjects was 2.5 millimeters and the mean difference between the displacements in the two knees in the patients was 7.5 millimeters. In fourteen of the sixty knees in which the ligament was ruptured, the injury was acute. The forward translation of the medial side in these fourteen knees was compared with that in the forty-six knees in which the injury was chronic. The mean difference in the displacement of the medial side in the right and left knees was 3.5 millimeters in the fourteen patients who had an acute injury and 5.0 millimeters in the forty-six patients who had a chronic injury. Thirteen of the sixty patients had disruption of the posteromedial corner of the injured knee, and the translation of the medial side in these knees was significantly increased compared with that in the intact knees of the same patients.(ABSTRACT TRUNCATED AT 250 WORDS)
