Crews Abstract: This manuscript reviews the proceedings of a symposium organized by Drs. Antonio Noronha and Fulton Crews presented at the 2003 Research Society on Alcoholism meeting. The purpose of the symposium was to examine recent findings on when alcohol induced brain damage occurs, e.g., during intoxication and/or during alcohol withdrawal. Further studies investigate specific brain regions (where) and the mechanisms (why) of alcoholic neurodegeneration. The presentations were (1) Characterization of Synaptic Loss in Cerebella of Mature and Senescent Rats after Lengthy Chronic Ethanol Consumption, (2) Ethanol Withdrawal Both Causes Neurotoxicity and Inhibits Neuronal Recovery Processes in Rat Organotypic Hippocampal Cultures, (3) Binge Drinking-Induced Brain Damage: Genetic and Age Related Effects, (4) Binge Ethanol-Induced Brain Damage: Involvement of Edema, Arachidonic Acid and Tissue Necrosis Factor , (TNF,), and (5) Cyclic AMP Cascade, Stem Cells and Ethanol. Taken together these studies suggest that alcoholic neurodegeneration occurs through multiple mechanisms and in multiple brain regions both during intoxication and withdrawal.

Methods This was a 4 week, double-blind, parallel-group trial. Thirty patients with mild to moderate degrees of TBI were randomly allocated to one of three treatment groups (n,=,10 in each group) with matching age, gender and education, i.e. methylphenidate (starting at 5,mg/day and increasing to 20,mg/day in a week), sertraline (starting at 25,mg/day and increasing to 100,mg/day in a week) or placebo. At the baseline and at the 4 week endpoint, the following assessments were administered: subjective (Beck Depression Inventory) and objective (Hamilton Depression Rating Scale) measures of depression; Rivermead Postconcussion Symptoms Questionnaire for postconcussional symptoms; SmithKline Beecham Quality of Life Scale for quality of life; seven performance tests (Critical Flicker Fusion, Choice Reaction Time, Continuous Tracking, Mental Arithmetic, Short-Term memory, Digit Symbol Substitution and Mini-Mental State Examination); subjective measures of sleep (Leeds Sleep Evaluation Questionnaire) and daytime sleepiness (Epworth Sleepiness Scale). All adverse events during the study period were recorded and their relationships to the drugs were assessed. Results Neuropsychiatric sequelae seemed to take a natural recovery course in patients with traumatic brain injury. Methylphenidate had significant effects on depressive symptoms compared with the placebo, without hindering the natural recovery process of cognitive function. Although sertraline also had significant effects on depressive symptoms compared with the placebo, it did not improve many tests on cognitive performances. Daytime sleepiness was reduced by methylphenidate, while it was not by sertraline. Conclusions Methylphenidate and sertraline had similar effects on depressive symptoms. However, methylphenidate seemed to be more beneficial in improving cognitive function and maintaining daytime alertness. Methylphenidate also offered a better tolerability than sertraline.

[source] Lack of evidence of the effectiveness of primary brachial plexus surgery for infants (under the age of two years) diagnosed with obstetric brachial plexus palsyINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2006Andrea Bialocerkowski PhD M App Sc (Physio) M App Sc (Physio) Grad Dip Public Health Abstract Background, Obstetric brachial plexus palsy, which occurs in 1,3 per 1000 live births, results from traction and/or compression of the brachial plexus in utero, during descent through the birth canal or during delivery. This results in a spectrum of injuries that range in extent of damage and severity and can lead to a lifelong impairment and functional difficulties associated with the use of the affected upper limb. Most infants diagnosed with obstetric brachial plexus palsy receive treatment, such as surgery to the brachial plexus, physiotherapy or occupational therapy, within the first months of life. However, there is controversy regarding the most effective form of management. This review follows on from our previous systematic review which investigated the effectiveness of primary conservative management in infants with obstetric brachial plexus palsy. This systematic review focuses on the effects of primary surgery. Objectives, The objective of this review was to systematically assess and collate all available evidence on effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Search strategy, A systematic literature search was performed using 13 databases: TRIP, MEDLINE, CINAHL, Web of Science, Proquest 5000, Evidence Based Medicine Reviews, Expanded Academic ASAP, Meditext, Science Direct, the Physiotherapy Evidence Database, Proquest Digital Dissertations, Open Archives Initiative Search Engine, the Australian Digital Thesis program. Those studies that were reported in English and published between July 1992 to June 2004 were included in this review. Selection criteria, Quantitative studies that investigated the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy were eligible for inclusion into this review. This excluded studies where infants were solely managed conservatively or with pharmacological agents, or underwent surgery for the management of secondary deformities. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion. Studies were also assessed for clinical homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format. Results, Twenty-one studies were included in the review. Most were ranked low on the hierarchy of evidence (no randomised controlled trials were found), and most had only fair methodological quality. Surgical intervention was variable, as were the eligibility criteria for surgery, the timing of surgery and the outcome instruments used to evaluate the effect of surgery. Therefore, it is difficult to draw conclusions regarding the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Conclusions, Although there is a wealth of information regarding the outcome following primary brachial plexus surgery it was not possible to determine whether this treatment is effective in increasing functional recovery in infants with obstetric brachial plexus palsy. Further research is required to develop standardised surgical criteria, and standardised outcome measures should be used at specific points in time during the recovery process to facilitate comparison between studies. Moreover, comparison groups are required to determine the relative effectiveness of surgery compared with other forms of management. [source] The trajectory of minor stroke recovery for men and their female spousal caregivers: literature reviewJOURNAL OF ADVANCED NURSING, Issue 6 2007Theresa L. Green Abstract Title.,The trajectory of minor stroke recovery for men and their female spousal caregivers: literature review Aim., This paper is a report of a narrative review to examine the current state of knowledge regarding the impact of minor stroke on male patients and their female spousal caregivers' recovery trajectory and quality of life. Background., Minor stroke survivors are often discharged early in the recovery process. The perception of the healthcare community that these patients and their female spousal caregivers will experience an uneventful recovery may lead to inadequate preparation for the postdischarge period. Methods., A range of databases was searched to identify papers addressing ,minor stroke', ,transitions', ,quality of life', ,chronic disease', ,caregivers' and ,spouse caregivers', including AARP Ageline, AMED, CINAHL, Evidence Based Medicine Reviews, MEDLINE and PsychInfo. Papers published in English from 1990 to December 2006 were included. Thirty-four papers were in the final data set. Results., Minor stroke survivors and their female spousal caregivers may experience major challenges in adaptations postdischarge. The trajectory of minor stroke recovery may necessitate a re-evaluation of life plans, rethinking of priorities and integration of resulting disabilities into current and emerging life situations for both stroke survivors and their female spousal caregivers. In many cases these adaptations are compounded by transitions associated with the normal ageing process. Conclusion., While there is extensive literature on stroke recovery and the role of caregivers in general, there is little available describing the recovery of minor stroke survivors in relation to the normal ageing process. Further research is needed examining recovery from a transitional perspective, to support nurses and other health professionals discharge planning. [source] Patients' recovery after critical illness at early follow-upJOURNAL OF CLINICAL NURSING, Issue 5-6 2010Michelle A Kelly Aim., To determine the quality of life, particularly physical function, of intensive care survivors during the early recovery process. Background., Survivors of critical illness face ongoing challenges after discharge from the intensive care unit and on returning home. Knowledge about health issues during early phases of recovery after hospital discharge is emerging, yet still limited. Design., Descriptive study where the former critically ill patients completed instruments on general health and quality of life (SF-36) in the first six months of recovery. Methods., Participants responded to the SF-36 questionnaire and questions about problems, one to six months after intensive care, either face-to-face or by telephone. Results., Thirty-nine participants had a mean age of 60 years; of them, 59% were men and had been in intensive care for 1,69 days (median = 5). Most participants (69%) rated their health as good or fair, but 54% rated general health as worse than a year ago. Mean quality of life scores for all scales ranged from 25,65·5%, with particularly low scores for Role-Physical (25) and Pain (45·1). Half the participants reported difficulty with mobility, sleep and concentration, and 72% that their responsibilities at home had changed. No relationships were found between SF-36 scores and admission diagnosis, gender, age or length of intensive care stay. Conclusions., These survivors of critical illness and hospitalisation in an intensive care unit perceive their general health to be good despite experiencing significant physical limitations and disturbed sleep during recovery. Relevance to clinical practice., Knowledge of issues in these early phases of recovery and discussion and resolution of patient problems could normalise the experience for the patient and help to facilitate better quality of life. [source] A review of psychosocial needs of breast-cancer patients and their relativesJOURNAL OF CLINICAL NURSING, Issue 21 2008Silvia Schmid-Büchi Aim., To identify the psychosocial needs of breast-cancer patients and their relatives along with factors affecting these needs and to develop a tentative model to guide further research and need assessments in clinical practice. Background., Women experiencing breast cancer must deal with the diagnosis of a life-threatening illness. Treatment and the recovery process can be demanding for patients and their relatives. Need assessment may help clinicians focus on providing appropriate help. Design., Literature review. Method., Undertaken using electronic databases and specific research terms; 20 articles were identified and analysed. Results., The needs identified by patients involve (1) treatment-related physical and social impairment like fatigue, menopausal symptoms and a changed body image and (2) emotional distress like fear of recurrence, anxiety and depression. Partners need help to protect themselves and the patient from different threats. Women need information to maintain control and manage their illness. Partners want information concerning the patient's condition and both of them about the prognosis and perspectives. There is a lack of knowledge of relatives' needs. Mutual familial support, women's and partners' health and emotional distress may affect the interaction between the patients and their partners. Conclusions., A tentative family-based model to guide further research and clinical support is proposed. Further research is needed to determine precisely which psychosocial factors may influence fulfilment of the patients' and relatives' needs. Relevance to clinical practice., The proposed model may provide a framework for healthcare professionals to evaluate the patients' and relatives' met and unmet needs and the real demand for help, to guide care planning, counselling and education. [source] Cultural and spiritual coping in sobriety: Informing substance abuse prevention for Alaska Native communitiesJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 5 2001Kelly L. Hazel Culture and spirituality have been conceptualized as both protecting people from addiction and assisting in the recovery process. A collaborative study, utilizing focus group and survey methods, defined and examined cultural and spiritual coping in sobriety among a select sample of Alaska Natives. Results suggest that the Alaska Native worldview incorporates a circular synthesis and balance of physical, cognitive, emotional, and spiritual processes within a protective layer of family and communal/cultural beliefs and practices embedded within the larger environment. Cultural-spiritual coping in sobriety is a process of appraisal, change, and connection that leads the person toward achieving an overarching construct: a sense of coherence. Cultural and spiritual processes provide important areas for understanding the sobriety process as well as keys to the prevention of alcohol abuse and addiction. © 2001 John Wiley & Sons, Inc. [source] Does service failure influence customer loyalty?JOURNAL OF CONSUMER BEHAVIOUR, Issue 3 2002Francis Buttle Abstract There is a general consensus that customer loyalty to service providers is not solely dependent upon their level of satisfaction or dissatisfaction. However, the identified antecedents of loyalty remain, at best, highly speculative. The aim of this extensive literature review is to give some understanding of the nature of customer loyalty and the antecedent effects of service dissatisfaction. The research reviewed suggests that customer loyalty is an attitudinal state, reflecting value, trust and commitment within supplier,customer relationships. Satisfaction is one of several antecedents of loyalty. A key influence on loyalty is the offer of unique value-delivering advantages not provided by competitors. Thus firms need to develop positive value-based exit barriers to achieve loyalty. When service failures occur, the recovery process is likely to have a greater impact on loyalty than the original service failure. The key to successful recoveries was found to be the customer's perception of ,fairness'. Recovery programmes must get it right first time. Customers who remain dissatisfied after a complaint has been handled are more dissatisfied than if no recovery attempt had been made. Dissatisfaction and customer satiation are major causes of a customer's exit. The solution to customer satiation is dynamic value creation. Collection and monitoring of customer data is needed for success and two-way communication is vital. Copyright © 2002 Henry Stewart Publications. [source] Measuring physiotherapists' guideline adherence by means of clinical vignettes: a validation studyJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 5 2006Geert M.J. Rutten MPH Abstract Rationale, aims and objectives, To assess the criterion validity of paper-and-pencil vignettes to assess guideline adherence by physiotherapists in the Netherlands. The evidence-based physiotherapy practice guideline for low back pain was used as an example. Methods, Four vignettes were constructed and pre-tested. Three vignettes were found to represent an adequate case-mix. They described one patient with specific low back pain, one with non-specific low back pain and a normal recovery process and one with non-specific low back pain and a delay in the recovery process. Invited to participate were 113 primary care physiotherapists who had joined an randomized controlled trial study 8 months before, in which guideline adherence had been measured by means of semi-structured treatment recording forms. The criterion validity was determined with Spearman's rs, using Cohen's classification for the behavioural sciences to categorize its effect size. Results, Of the 72 physiotherapists who agreed to participate, 39 completed the questions on the vignettes. In the end, both adherence measures were available for 34 participants, providing 102 vignettes and 268 recording forms. Mean guideline adherence scores were 57% (SD = 17) when measured by vignettes and 74% (SD = 15) when measured by recording forms. Spearman's rs was 0.31 (P = 0.036), which, according to Cohen's classification, is a medium effect size. Conclusion, Vignettes are of acceptable validity, and are an inexpensive and manageable instrument to measure guideline adherence among large groups of physiotherapists. Further validation studies could benefit from the use of standardized patients as a gold standard, a more diverse case mix to better reflect real physiotherapy practice, and the inclusion of longitudinal vignettes that cover the patients' course of treatment. [source] A new recovery process of carbon dioxide from alkaline carbonate solution via electrodialysisAICHE JOURNAL, Issue 12 2009Hiroki Nagasawa Abstract Bipolar membrane electrodialysis is applied to CO2 recovery from alkaline carbonate solution. CO2 in flue gas is captured by an alkaline hydroxide absorbing solution to form an alkaline carbonate solution. The captured CO2 is recovered from the alkaline carbonate solution via bipolar membrane electrodialysis, and the alkaline solution is regenerated simultaneously. To reduce the power requirement for CO2 recovery, this study considers optimal design and operation. Three membrane arrangements were compared, and the results indicate the membrane arrangement comprising a bipolar membrane and cation exchange membrane is the most energy saving. With further optimization of operation conditions, the minimum power requirement for CO2 recovery was reduced to 2.1 MJ/kg-CO2 (or 2.1 GJ/t-CO2). © 2009 American Institute of Chemical Engineers AIChE J, 2009 [source] Family Network Support and Mental Health RecoveryJOURNAL OF MARITAL AND FAMILY THERAPY, Issue 1 2010Francesca Pernice-Duca Family members often provide critical support to persons living with a serious mental illness. The focus of this study was to determine which dimensions of the family support network were most important to the recovery process from the perspective of the recovering person. Consumers of a community mental health program completed in-depth structured interviews that included separate measures of social network support and recovery. Consumers named an average of 2.6 family members on the social network, interacted with family on a weekly basis, and were quite satisfied with their contact. This study revealed that support and reciprocity with family members are important dimensions of a personal support network that relates to the recovery process. [source] Optical and physicochemical properties of silica-supported TiO2 photocatalystsAICHE JOURNAL, Issue 8 2006Javier Marugán Abstract Commercial applications of photocatalysis in slurry reactors employing titanium dioxide particles present the disadvantage of the additional cost associated with the downstream catalyst separation. In past years a significant effort has been made to develop supported titania photocatalysts on particles of larger size in order to facilitate the sedimentation recovery process. In this work, two different silica materials have been used for preparing immobilized catalysts. Their physicochemical characteristics have been compared with those corresponding to two commercially available unsupported titanium dioxide catalysts. However, for reaction kinetics and reactor design purposes, three additional properties must be known: (i) the spectral specific radiation absorption coefficient, (ii) the spectral specific radiation scattering coefficient, and (iii) the asymmetry factor of a model for the angular distribution of the scattered photons (the phase function). They have been determined with specially designed spectrophotometer transmission, diffuse transmittance, and diffuse reflectance experiments and constitute the most significant addition to this contribution. © 2006 American Institute of Chemical Engineers AIChE J, 2006 [source] Chronic Stress, Sense of Belonging, and Depression Among Survivors of Traumatic Brain InjuryJOURNAL OF NURSING SCHOLARSHIP, Issue 3 2002Esther Bay Purpose: To test whether chronic stress, interpersonal relatedness, and cognitive burden could explain depression after traumatic brain injury (TBI). Design: A nonprobability sample of 75 mild-to-moderately injured TBI survivors and their significant others, were recruited from five TBI day-rehabilitation programs. All participants were within 2 years of the date of injury and were living in the community. Methods: During face-to-face interviews, demographic information, and estimates of brain injury severity were obtained and participants completed a cognitive battery of tests of directed attention and short-term memory, responses to the Perceived Stress Scale, Interpersonal Relatedness Inventory, Sense of Belonging Instrument, Neurobehavioral Functioning Inventory, and Center for Epidemiological Studies Depression Scale;. Findings: Chronic stress was significantly and positively related to post-TBI depression. Depression and postinjury sense of belonging were negatively related. Social support and results from the cognitive battery did not explain depression. Conclusions: Postinjury chronic stress and sense of belonging were strong predictors of post-injury depression and are variables amenable to interventions by nurses in community health, neurological centers, or rehabilitation clinics. Future studies are needed to examine how these variables change over time during the recovery process. [source] Masticatory jaw movement optimization after introduction of occlusal interferenceJOURNAL OF ORAL REHABILITATION, Issue 3 2010K. YASHIRO Summary, How ,control' characteristics of masticatory jaw movement, such as skilfulness of the movement, change after alteration in occlusion remains uncertain. For each of 10 healthy adults with good occlusion, an occlusal interference with artificial ,tooth-cusp' was introduced to the crown of the upper molar tooth on the non-working side of unilateral chewing. Mandibular incisor-point movements were then recorded by a 3D tracking device. The introduction of the occlusal interference induced a remarkable increase in the normalized jerk-cost (NJC), prolonged duration of the decelerative phase and lowered peak velocity for jaw closing movement during chewing. Overall, the NJC and velocity profile showed significant recoveries during the course of about 90 repetitive chewing cycles performed under the altered occlusal condition. These findings suggest that acute adaptive changes of jaw motion after introduction of occlusal interference might be characterized as the recovery process of movement skilfulness in terms of movement smoothness and velocity profile. [source] The pathophysiological basis of acute-on-chronic liver failureLIVER INTERNATIONAL, Issue 2002S Sen Abstract: The vast majority of patients that are referred to a specialist hepatological centre suffer from acute deterioration of their chronic liver disease. Yet, this entity of acute-on-chronic liver failure remains poorly defined. With the emergence of newer liver support strategies, it has become necessary to define this entity, its pathophysiology and the short and long-term prognosis. This review focuses upon how a precipitant such as an episode of gastrointestinal bleeding or sepsis may start a cascade of events that culminate in end-organ dysfunction and liver failure. We briefly review the pathophysiological basis of the therapeutic modalities that are available. Our current strategy for the management of liver failure involves supportive therapy for the end-organs with the hope that the liver function would recover if sufficient time for such a recovery is allowed. Because liver failure, whether of the acute or acute-on-chronic variety, is potentially reversible, the stage is set for the application of newer liver support strategies to enhance the recovery process. [source] Mechanism of excitation and relaxation in Er,O-codoped GaAs for 1.5 ,m light-emitting devices with extremely stable wavelengthPHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 1 2008Yasufumi Fujiwara Abstract Energy-transfer processes in Er,O-codoped GaAs (GaAs:Er,O) have been investigated by means of a pump and probe reflection technique. Time-resolved reflectivity exhibited a characteristic dip; a negative signal due to bandgap renormalization in less than 1 ps and then a gradual recovery. In the recovery process, there were two components, fast and slow. The fast recovery time (several ps) was inversely proportional to Er concentration. The analysis based on a rate equation indicated that it is due to the capture of electrons by charged traps. The slow recovery (30,60 ps) was well coincident with the time (54 ps) predicted theoretically in the framework of a multiphonon-assisted model. Optical excitation cross section of Er ions in GaAs:Er,O has also been studied in various samples and shown to depend strongly on Er concentration. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source] Another Breed of "Service" Animals: STARS Study Findings About Pet Ownership and Recovery From Serious Mental IllnessAMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 3 2009Jennifer P. Wisdom PhD This study elucidates the role of pets in recovery processes among adults with serious mental illness. Data derive from interviews with 177 HMO members with serious mental illness (52.2% women, average age 48.8 years) in the Study of Transitions and Recovery Strategies (STARS). Interviews and questionnaires addressed factors affecting recovery processes and included questions about pet ownership. Data were analyzed using a modified grounded theory method to identify the roles pets play in the recovery process. Primary themes indicate pets assist individuals in recovery from serious mental illness by (a) providing empathy and "therapy"; (b) providing connections that can assist in redeveloping social avenues; (c) serving as "family" in the absence of or in addition to human family members; and (d) supporting self-efficacy and strengthening a sense of empowerment. Pets appear to provide more benefits than merely companionship. Participants' reports of pet-related contributions to their well-being provide impetus to conduct more formal research on the mechanisms by which pets contribute to recovery and to develop pet-based interventions.

USAMI National Center of Neurology and Psychiatry, Kohnodai Hospital, Chiba, Japan This is a case report of a 13-year-old-boy (2nd grade in junior high school). His father had poor communication; his mother was a very fragile woman. The boy had been overprotected by his parents, as long as he responded to their expectations. He did not have any other siblings. He played well with his friends since he was young, and did not have problems until the 1st term (from April to July) of 1st grade in junior high school. However, in September he started to have difficulties going well with his friends, and going to school. He spent most of his time in his room, and began to repeat checking and hand-washing frequently. Even at midnight, he forced his mother to touch the shutter from outside of the house for many times. He also ritually repeated to touch his mother's body, after he licked his hands, for over an hour. He became violent, when his parents tried to stop him. In April, year X, his parents visited our hospital for the first time. From then, his mother could not tolerate her son's coerciveness any longer. His father explained to the boy that ,your mother has been hospitalized', and she started to live in the next room to the boy's without making any noise. After 3 months he noticed that his mother was not hospitalized, and he got very excited. He was admitted to our hospital with his family and relatives, in October, year X. At the initial stage of hospitalization he showed distrust and doubt towards the therapist and hospital. He had little communication with other boys and did not express his feelings. Therefore, there was a period of time where he seemed to wonder whether he could trust the treatment staff or not. During his interviews with his therapist he repeated only ,I'm okay' and did not show much emotional communication. For the boy, exposing himself was equivalent to showing his vulnerability and incompleteness. Therefore, the therapist considered that he was trying to denying his feelings to avoid this. The therapist set goals for considering his own feelings positively and expressing them appropriately. Also, the therapist carried out behavioral restrictions towards him. He hardly had any emotional communication with the staff, and his peer relationship in the ward was superficial. Therefore, he gradually had difficulty spending his time at the end of December On the following day in which he and the therapist decided to return to his house for the first time, he went out of the ward a few days before without permission. From thereon it was possible for him to share feelings such as hostility and aggression, dependence and kindness with the therapist. The therapist changed his role from an invasive one to a more protective one. Then, his unsociability gradually faded. He also developed good peer relationships with other boys in the ward and began to express himself feeling appropriately. He was also able to establish appropriate relations with his parents at home, and friends of his neighborhood began to have normal peer relationships again. During childhood and adolescence, boys with obsessive,compulsive disorder are known to have features such as poor insight and often involving their mothers. We would like to present this case, through our understanding of dynamic psychiatry throughout his hospitalization, and also on the other therapies that were performed. Psychotherapy with a graduate student that discontinued after only three sessions: Was it enough for this client? N. KATSUKI Sophia University, Tokyo, Japan Introduction: Before and after the psychotherapy, SWT was administrated in this case. Comparing these two drawings, the therapist was provided with some ideas of what kind of internal change had taken place inside this client. Referring to the changes observed, we would like to review the purposes and the ways of the psychotherapy, as well as the adequacy of the limited number of the sessions (vis-a-vis result attained.) Also we will discuss later if any other effective ways could be available within the capacities of the consulting system/the clinic in the university. Case: Ms. S Age 24 years. Problems/appeal: (i) awkwardness in the relationship with the laboratory colleagues; (ii) symptoms of sweating, vomiting and quivering; and (iii) anxiety regarding continuing study and job hunting. Diagnosis: > c/o PTSD. Psychotherapeutic setting: At the therapy room in the clinic, placed at the university, 50 min-session; once a week; paralleled with the medical treatment. Process: (1) Since she was expelled from the study team in the previous year, it has become extremely difficult for her to attend the laboratory (lab) due to the aforementioned symptoms. She had a feeling of being neglected by the others. When the therapist suggested that she compose her mental confusions in the past by attending the therapy room, she seemed to be looking forward to it, although she said that she could remember only a few. (2) She reported that she overdosed on sedatives, as she could not stop irritating. She was getting tough with her family, also she slashed the mattress of her bed with a knife for many times. She complained that people neither understood nor appreciated her properly. and she said that she wanted revenge on the leader of the lab by punishing him one way or other. (3) Looking back the previous session, she said ,I had been mentally mixed up at that time, but I feel that now I can handle myself, as I stopped the medication after consulting the psychiatrist. According to what she said, when she disclosed the occurrences in the lab to her mother, she felt to be understood properly by her mother and felt so relieved. and she also reported that she had been sewing up the mattress which she slashed before, without any reason. She added, " although I don't even know what it means, I feel that this work is so meaningful to me, somehow". Finally, she told that she had already made her mind to cope with the situation by herself from now on, although it might result in a flinch from the real solution. Situations being the above, the session was closed. Swt: By the remarkable changes observed between the two drawings, the meanings of this psychotherapy and its closure to the client would be contemplated.

ASAHARA Sophia University, Tokyo, Japan Although time limited relationship is one of the important characteristics in school counseling, the question of separation attendant on it has not been much discussed based on specific cases. This study focuses on the question of separation through looking at a particular case, in which the separation was not worked through, and halfway relationship continued even after the student's graduation and the counselor's resignation. I was a part time school counselor at a junior high school in Tokyo. The client was a 14-year-old female student, who could not go to her classroom, and spent a few hours in a sick bay when she came to school. She was in the final grade and there was only half a year left before graduation when we first met, and we started to see each other within a very loose structure. As her personality was hyper-vigilant and defensive, it took almost 2 months before I could feel that she was nearer. Her graduation was the first occasion of separation. On that occasion, I found that there had been a discrepancy between our expectations; while I took it for granted that our relationship would end with the graduation, she expected to see me even after she graduated, and she actually came up to see me once in a while during the next year. A year later, we faced another occasion of separation, that was my resignation. Although I worried about her, all I have done for her was to hand a leaflet of a counseling office, where I work as a part time counselor. Again I could not refer to her feelings or show any concrete directions such as making a fixed arrangement. After an occasional correspondence for the next 10 months (about 2 years after her graduation), she contacted me at the counseling office asking for a constant counseling. Why could I not deal with both occasions? and how did that affect the client thereafter? There were two occasions of separation. At the time of the client's graduation, I seemed to be enmeshed in the way of separation that is peculiar to the school setting. In general in therapeutic relationship, mourning work between counselor and client is regarded as being quite important. At school, however, separation attendant on graduation is usually taken for granted and mourning work for any personal relationship tends to be neglected. Graduation ceremony is a big event but it is not about mourning over one's personal relationships but separation from school. That may be why I did not appreciate how the client counted on our relationship. At the time of my resignation I was too worried about working through a change from very loose structure which is peculiar to the school setting to a usual therapeutic structure (fees are charged, and time, place are fixed). That is why I did nothing but give her a leaflet. In this way, we never talked about her complex feelings such as sadness or loneliness, which she was supposed to experience on separation. Looking at the aforementioned process from the client's viewpoint, it can be easily imagined that she could not accept the fact of separation just because she graduated. and later, she was forced to be in double-bind situation, in which she was accepted superficially (handed a leaflet), while no concrete possibility was proposed concerning our relationship (she could never see me unless she tries to contact me.) As a result, she was left alone and at a loss whether she could count on me or not. The halfway situation or her suspense was reflected in her letter, in which she appeared to be just chatting at first sight, but between the lines there was something more implying her sufferings. Above discussion suggests that in some case, we should not neglect the mourning work even in a school setting. To whom or how it is done is the next theme we should explore and discuss in the future. For now, we should at least be conscious about the question of separation in school setting. Study of the process of psychotherapy with intervals for months M. TERASHIMA Bunkyo Gakuin University, Tokyo, Japan This is a report on the process of psychotherapy of an adolescent girl who showed manic and depressive state. At the time of a depressed state, she could not go to a college and withdrew into home, and the severe regressive situation was shown. Her therapy began at the age of 20 and she wanted to know what her problem was. The process of treatment went on for 4 years but she stopped coming to sessions for several months because of failure of the therapist. She repeated the same thing twice. After going through these intervals the client began to remember and started to talk about her childhood , suffering abusive force from her father, with vivid impressions. They once were hard for her to accept, but she began to establish the consistent figure of herself from past to present. In this case, it could be thought that the intervals of the sessions had a certain role, with which the client controlled the structure of treatment, instead of an attack against the therapist. Her object relation, which is going to control an object offensively, was reflected in these phenomena. That is, it can be said that the ambivalence about dependency , difficult to depend but desirous of the object , was expressed. Discontinuation of the sessions was the product of the compromise formation brought about the ambivalence of the client, and while continuing to receive this ambivalence in the treatment, the client started to realize discontinuance of her memories and then advanced integration of her self-image. For the young client with conflict to dependence such as her, an interval does not destroy the process of treatment but in some cases it could be considered as a therapeutic element. In the intervals the client could assimilate the matter by herself, that acquired by the sessions. Psychotherapy for a schizoid woman who presented eccentric speech and behaviour M. OGASAWARA Osaka University Graduate School of Medicine, Osaka, Japan Case presentation: A case of a 27-year-old woman at the beginning of therapy. Life history: She had been having a wish for death since she was in kindergarten and she had been feeling strong resistance to do the same as others after school attendance. She had a history of ablutomania from the age of 10,15, but the symptom disappeared naturally. and she said that she had been eliminated from groups that she tried to enter. After graduating a junior college, she changed jobs several times without getting a full-time position. Present history: Scolded by her boy friend for her coming home too late one day, she showed confusion such as excitement, self-injury or terror. She consulted a psychiatrist in a certain general hospital, but she presented there eccentric behaviours such as tense facial expression, stiffness of her whole body, or involuntary movement of limbs. and because she felt on bad terms with the psychiatrist and she had come to cause convulsion attacks in the examination room, she was introduced to our hospital. Every session of this psychotherapy was held once a week and for approximately 60 min at a time. Treatment process: She sometimes presented various eccentric attitudes, for example overturning to the floor with screaming (1), going down on her knees when entrance at the door (5), entering with a knife in her mouth and hitting the wall suddenly (7), stiffening herself just outside the door without entering the examination room (9), taking out a knife abruptly and putting it on her neck (40), exclaiming with convulsion responding to every talk from the therapist (41), or stiffening her face and biting herself in the right forearm suddenly (52). She also repeated self-injuries or convulsion attacks outside of the examination room in the early period of the therapy. Throughout the therapy she showed hypersensitivity for interpersonal relations, anxiety about dependence, terror for self-assertion, and avoidance for confrontation to her emotional problems. Two years and 6 months have passed since the beginning of this therapy. She ceased self-injury approximately 1 year and 6 months before and her sense of obscure terror has been gradually reduced to some extent. Discussion: Her non-verbal wariness and aggression to the therapist made the sessions full of tension and the therapist felt a sense of heaviness every time. In contrast, she could not express aggression verbally to the therapist, and when the therapist tried to identify her aggression she denied it. Her anxiety, that she will be thoroughly counterattacked to self-disintegration if she shows aggression to other persons, seems to be so immeasurably strong that she is compelled to deny her own aggression. Interpretations and confrontations by the therapist make her protective, and occasionally she shows stronger resistance in the shape of denial of her problems or conversion symptoms (astasia, aphonia, or involuntary movements) but she never expresses verbal aggression to the therapist. and the therapist feels much difficulty to share sympathy with her, and she expresses distrust against sympathetic approach of the therapist. However, her obvious disturbance that she expresses when she feels the therapist is not sympathetic shows her desire for sympathy. Thus, because she has both strong distrust and desire for sympathy, she is in a porcupine dilemma, which is characteristic of schizoid patients as to whether to lengthen or to shorten the distance between herself and the therapist. This attitude seems to have been derived from experience she might have had during her babyhood and childhood that she felt terror to be counterattacked and deserted when she showed irritation to her mother. In fact, existence of severe problems of the relationship between herself and her mother in her babyhood and childhood can be guessed from her statement. Although she has been repeating experiences to be excluded from other people, she shows no attitude to construct interpersonal relationship actively. On the contrary, by regarding herself to be a victim or devaluating other persons she externalizes responsibility that she herself should assume essentially. The reason must be that her disintegration anxiety is evoked if she recognizes that she herself has problems; that is, that negative things exist inside of her. Therefore, she seems to be inhibited to get depressive position and obliged to remain mainly in a paranoid,schizoid position. As for the pathological level, she seems to have borderline personality organization because of frequent use of mechanisms to externalize fantastically her inner responsibility. For her high ability to avoid confronting her emotional problems making the most of her verbal ability, every intervention of the therapist is invalidated. So, it seems very difficult for her to recognize her own problems through verbal interpretations or confrontation by the therapist, for the present. In general, it is impossible to confront self problems without containing negative emotions inside of the self, but her ability seemed to be insufficient. So, to point out her problems is considered to be very likely to result in her confusion caused by persecution anxiety. Although the therapy may attain the stage on which verbal interpretation and confrontation work better some day, the therapist is compelled to aim at promoting her ability to hold negative emotion inside of herself for the time being. For the purpose, the therapist is required to endure the situation in which she brings emotion that makes the therapist feel negative counter-transference and her process to experience that the therapeutic relation itself would not collapse by holding negative emotion. On supportive psychotherapy with a male adolescent Y. TERASHIMA Kitasato University Health Care Center, Kanagawa, Japan Adolescent cases sometimes show dramatic improvements as a consequence of psychotherapy. The author describes how psychotherapy can support an adolescent and how theraputic achievements can be made. Two and a half years of treatment sessions with a male adolescent patient are presented. The patient was a 19-year-old man, living with his family. He had 5 years of experience living abroad with his family and he was a preparatory school student when he came to a mental clinic for help. He was suffering from not being able to sleep well, from difficulties concerning keeping his attention on one thing, and from fear of going to distant places. He could barely leave his room, and imagined the consequence of overdosing or jumping out of a window. He claimed that his life was doomed because his family moved from a town that was familiar to him. At the first phase of psychotherapy that lasted for approximately 1 year, the patient seldom responded to the therapist. The patient was basically silent. He told the therapist that the town he lives in now feels cold or that he wants to become a writer. However, these comments were made without any kind of explanation and the therapist felt it very difficult to understand what the patient was trying to say. The sessions continued on a regular basis. However, the therapist felt very useless and fatigued. Problems with the patient and his family were also present at this phase of psychotherapy. He felt unpleasant at home and felt it was useless to expect anything from his parents. These feelings were naturally transferred to the therapist and were interpreted. However, interpretation seemed to make no changes in the forms of the patient's transference. The second phase of psychotherapy began suddenly. The patient kept saying that he did not know what to talk about. However, after a brief comment made by the therapist on the author of the book he was reading, the patient told the therapist that it was unexpected that the therapist knew anything of his favorite writer. After this almost first interaction between the patient and the therapist, the patient started to show dramatic changes. The patient started to bring his favorite rock CDs to sessions where they were played and the patient and the therapist both made comments on how they felt about the music. He also started asking questions concerning the therapist. It seemed that the patient finally started to want to know the therapist. He started communicating. The patient was sometimes silent but that did not last long. The therapist no longer felt so useless and emotional interaction, which never took place in the first phase, now became dominant. The third phase happened rapidly and lasted for approximately 10 months. Conversations on music, art, literature and movies were made possible and the therapist seldom felt difficulties on following the patient's line of thought. He started to go to schools and it was difficult at first but he started adjusting to the environment of his new part-time jobs. By the end of the school year, he was qualified for the entrance to a prestigious university. The patient's problems had vanished except for some sleeping difficulties, and he did not wish to continue the psychotherapy sessions. The therapist's departure from the clinic added to this and the therapy was terminated. The patient at first reminded the therapist of severe psychological disturbances but the patient showed remarkable progress. Three points can be considered to have played important roles in the therapy presented. The first and the most important is the interpretation by behavior. The patient showed strong parental transference to the therapist and this led the therapist to feel useless and to feel fatigue. Content analysis and here-and-now analysis seemed to have played only a small part in the therapy. However, the therapist tried to keep in contact with the patient, although not so elegant, but tried to show that the therapist may not be useless. This was done by maintaining the framework of the therapy and by consulting the parents when it was considered necessary. Second point is the role that the therapist intentionally took as a model or target of introjection. With the help of behavioral interpretation that showed the therapist and others that it may not be useless, the patient started to introject what seemed to be useful to his well being. It can be considered that this role took some part in the patient going out and to adjust to the new environment. Last, fortune of mach must be considered. The patient and the therapist had much in common. It was very fortunate that the therapist knew anything about the patient's favorite writer. The therapist had some experience abroad when he was young. Although it is a matter of luck that the two had things in common, it can be said that the congeniality between the patient and the therapist played an important role in the successful termination of the therapy. From the physical complaint to the verbal appeal of A's recovery process to regain her self-confidence C. ITOKAWA and S. KAZUKAWA Toyama Mental Health Center, Toyama, Japan This is one of the cases at Toyama Mental Health Center about a client here, we will henceforth refer to her simply as ,A'. A was a second grade high school student. We worked with her until her high school graduation using our center's full functions; counseling, medical examination and the course for autogenic training (AT). She started her counseling by telling us that the reason for her frequent absences from school began because of stomach pains when she was under a lot of stress for 2 years of junior high school, from 2nd grade to 3rd grade. Due to a lack of self confidence and a constant fear of the people around her, she was unable to use the transportation. She would spend a large amount of time at the school infirmary because she suffered from self-diagnosed hypochondriac symptoms such as nausea, diarrhea and a palpitation. She continued that she might not be able to have the self-confidence to sit still to consult me on her feelings in one of our sessions. A therapist advised her to take the psychiatric examination and the use of AT and she actually saw the medical doctor. In counseling (sessions), she eventually started to talk about the abuse that started just after her entering of junior high school; she approached the school nurse but was unable to tell her own parents because she did not trust them. In doing so, she lost the rest of her confidence, affecting the way she looked at herself and thought of how others did. At school she behaved cheerfully and teachers often accused her of idleness as they regarded this girl's absences along with her brightly dyed hair and heavy make-up as her negligent laziness. I, as her therapist, contacted some of the school's staff and let them know of her situation in detail. As the scolding from the teachers decreased, we recognized the improvement of her situation. In order to recover from the missed academic exposure due to her long absence, she started to study by herself. In a couple of months her physical condition improved gradually, saying ,These days I have been doing well by myself, haven't I?' and one year later, her improved mental condition enabled her to go up to Tokyo for a concert and furthermore even to enjoy a short part-time job. She continued the session and the medical examination dually (in tangent) including the consultation about disbelief to the teachers, grade promotion, relationships between friends and physical conditions. Her story concentrated on the fact that she had not grown up with sufficiently warm and compassionate treatment and she could not gain any mental refuge in neither her family nor her school, or even her friends. Her prospects for the future had changed from the short-ranged one with no difficulty to the ambitious challenge: she aimed to try for her favorite major and hoped to go out of her prefecture. But she almost had to give up her own plan because the school forced her to change her course as they recommended. (because of the school's opposition with her own choice). So without the trust of the teachers combined with her low self-esteem she almost gave up her hopes and with them her forward momentum. In this situation as the therapist, I showed her great compassion and discussed the anger towards the school authorities, while encouraging this girl by persuading her that she should have enough self-confidence by herself. Through such sessions, she was sure that if she continued studying to improve her own academic ability by herself she could recognize the true meaning of striving forward. and eventually, she received her parents' support who had seemed to be indifferent to her. At last she could pass the university's entrance exams for the school that she had yearned to attend. That girl ,A' visited our center 1 month later to show us her vivid face. I saw a bright smile on her face. It was shining so brightly. [source] An interactive process model of psychosocial support needs for women living with breast cancer,PSYCHO-ONCOLOGY, Issue 4 2003Beth Marlow Psychosocial support is acknowledged as an important aspect of the care and recovery process for women diagnosed with breast cancer. To develop an understanding of support needs, a series of focus groups were conducted with a total of 80 Australian women living with breast cancer. The psychosocial needs identified in discussion were summarised into four main categories, Organisation of Care, Sense of Control, Validation of Experience and Feeling of Reassurance. From these themes an interactive model of psychosocial support needs was developed. As a process model it demonstrates that the provision of effective support is, necessarily, an integrated, not a piecemeal, process. The categories of support are broad, and are made more inclusive through interactions with each other, providing room to accommodate individual needs and styles of adjustment. The model is not esoteric or complicated , it is an accessible overview of the process for both client and helper. Copyright © 2003 John Wiley & Sons, Ltd.

[source] Polycyclic aromatic hydrocarbons (PAHs) adsorption on solid surfaces applied to waste lubricant oils recovery processTHE CANADIAN JOURNAL OF CHEMICAL ENGINEERING, Issue 3 2010José Lima Assunção Filho Abstract Lubricant oils undergo degradation increasing polycyclic aromatic hydrocarbons (PAHs) concentration. In this work, PAHs adsorption onto activated carbon, powder silica, and powder chitosan surfaces was estimated, with their concentrations in organic solvents (ethanol, 2-propanol, 1-butanol, and terc -butanol) monitored by UV-visible absorption. Equilibrium concentration was attained after 72,h and the isotherms presented characteristic of multilayer formation. The greater surface density was determined for the chitosan, but the system containing activated carbon and 1-butanol presented better efficiency for PAHs removal. Results indicated that the adsorption evaluated in this work can be a potential stage in the waste lubricant oils global recovery process. Les huiles de lubrification subissent une dégradation augmentant la concentration d'hydrocarbures aromatiques polycycliques (HAP). Dans ce travail, on a estimé l'adsorption de HAPs sur du carbone activé, de la silice en poudre et des surfaces de chitosane en poudre, leurs concentrations dans des solvants organiques (éthanol, 2-propanol, 1-butanol et terc -butanol) étant suivies par absorption UV et dans le domaine visible. Une concentration d'équilibre a été atteinte après 72,h et les isothermes présentaient des caractéristiques de formation de couches multiples. La densité de surface la plus importante a été déterminée pour le chitosane mais le système contenant du carbone activé et du 1-butanol présentait une meilleure efficience en matière de retrait des HAPs. Les résultats indiquaient que l'adsorption évaluée dans ce travail pourrait constituer une étape potentielle du processus global de récupération des résidus d'huiles de lubrification.

Experiments and computer simulations using MatlabÔ are conducted at different operating conditions. The effects of hydro-dynamic parameters and kinetic parameters on the performance of the LSCFB ion exchange system are discussed. The model is shown to be applicable for the design of LSCFB ion exchange systems for protein recovery. On décrit dans cette étude un procédé de récupération de protéines continu utilisant un système d'échange d'ions à lit fluidisé circulant liquide-solide (LSCFB) ainsi qu'un modèle basé sur une cinétique connue. Des expériences et des simulations par ordinateur à l'aide de MatlabÔ sont menées pour différentes conditions de fonctionnement. Les effets des paramètres hydrodynamiques et des paramètres cinétiques sur la performance du système d'échange d'ions LSCFB sont analysés. On montre que le modèle est applicable à la conception de systèmes d'échange d'ions LSCFB pour la récupération de protéines. [source] Identification of regulatory pathways involved in the reacquisition of root growth after salt stress in Medicago truncatulaTHE PLANT JOURNAL, Issue 1 2007Francisco Merchan Summary Root growth and function are determined by the action of environmental stresses through specific genes that adapt root development to these restrictive conditions. We have defined in vitro conditions affecting the growth and recovery of Medicago truncatula roots after a salt stress. A dedicated macroarray containing 384 genes, based on a large-scale subtractive hybridization approach, was constructed and used to analyze gene expression during salt stress and recovery of root growth from this stress. Several potential regulatory genes were identified as being linked to this recovery process: a novel RNA-binding protein, a small G-protein homologous to ROP9, a receptor-like kinase, two TF IIIA-like and an AP2-like transcription factors (TF), MtZpt2-1, MtZpt2-2 and MtAp2, and a histidine kinase associated with cytokinin transduction pathways. The two ZPT2-type TFs were also rapidly induced by cold stress in roots. By analyzing transgenic M. truncatula plants showing reduced expression levels of both TFs and affected in their capacity to recover root growth after a salt stress, we identified potential target genes that were either activated or repressed in these plants. Overexpression of MtZpt2-1 in roots conferred salt tolerance and affected the expression of three putative targets in the predicted manner: a cold-regulated A (CORA) homolog, a flower-promoting factor (FPF1) homolog and an auxin-induced proline-rich protein (PRP) gene. Hence, regulatory networks depending on TFIIIA-like transcription factors are involved in the control of root adaptation to salt stress. [source] Pricing credit derivatives under stochastic recovery in a hybrid modelAPPLIED STOCHASTIC MODELS IN BUSINESS AND INDUSTRY, Issue 3 2010Stephan Höcht Abstract In this article, a framework for the joint modelling of default and recovery risk is presented. The model accounts for typical characteristics known from empirical studies, e.g. negative correlation between recovery-rate process and default intensity, as well as between default intensity and state of the economy, and a positive dependence of recovery rates on the economic environment. Within this framework analytically tractable pricing formulas for credit derivatives are derived. The stochastic model for the recovery process allows for the pricing of credit derivatives with payoffs that are directly linked to the recovery rate at default, e.g. recovery locks.

[source] The Characterization of Contractile and Myoelectric Activities in Paralyzed Tibialis Anterior Post Electrically Elicited Muscle FatigueARTIFICIAL ORGANS, Issue 4 2010Nan-Ying Yu Abstract This study aimed to understand the myoelectric and mechanical characteristics of muscle recovering from electrically elicited fatigue. A modified Burke fatigue protocol was delivered to activate the tibialis anterior of 13 spinal cord injured subjects for 4 min. Before and after the fatigue protocol, a series of pulse trains was delivered to induce three twitches and a fused contraction at 0, 1, 3, and 5 min and then followed every 5 min for 60 min. The recovery processes of the ankle dorsiflexion torque and the evoked electromyography (EMG) parameters were analyzed and characterized by a first-order exponential equation. The recovery process was found to be faster in regard to tetanic muscle contraction. Factors relating to low-frequency fatigue, postfatigue potentiation, and the quickly normalized relaxation rate were taken into account for the discussion of this result. During the recovery process, the disassociation was found not only between twitch and tetanic contractions but also between mechanical and myoelectric activities. After the complete normalization of EMG parameters from about 15 min post fatigue, the tetanic force recovered incompletely to an asymptotic level. [source] Committing to regional cooperation: ASEAN, globalisation and the Shin Corporation , Temasek Holdings dealASIA PACIFIC VIEWPOINT, Issue 3 2009Sajid Anwar Abstract This paper investigates the relationship between regional and national identities in the age of globalisation, with particular reference to the Association of Southeast Asian Nations (ASEAN). For members of ASEAN, economic integration is seen as a necessary step forward in order to (i) reduce reliance on Western countries during times of economic crisis and (ii) speed up the recovery process in the aftermath of a crisis. The concept of an ASEAN Economic Community represents a step towards achieving this goal. However, by means of a case study, this paper demonstrates that the idea of an ASEAN Economic Community does not yet have sufficiently solid foundations. Cracks appear when member states act in response to national interest. Given the frequency of friction between member nations, and the fact that ASEAN members are quite diverse in both economic and cultural respects, there is still much more to be done to realise the objective of forming an effective and credible regional economic group. In this paper some suggestions are offered that might assist with the achievement of this goal. [source] Untersuchung zur Lärmbelastung von Patienten und Pflegepersonal auf IntensivstationenBAUPHYSIK, Issue 4 2007Jörg Arnold Dipl.-Ing. Zur Untersuchung der Lärmbelastung auf Intensivstationen in Krankenhäusern wurden Schalldruckpegelmessungen sowohl in einem Patientenzimmer als auch in dem Foyer einer Intensivstation durchgeführt. Im Patientenzimmer wird eine hohe Lärmbelastung festgestellt. Zudem belegen die Messergebnisse, dass in jeder untersuchten Stunde Lärmereignisse auftraten, die leicht zum Aufwachen führen. Diese hohe Lärmdichte hat einen dramatischen Einfluss auf den Schlaf und damit auf die Erholung und Gesundung des Patienten. Es wurde eine für gesunde Patienten "sichere Aufwachschwelle" definiert, die auch in der Nacht im Mittel 5 mal je Stunde überschritten wird. Allerdings existieren in Deutschland bisher keine Grenzwerte zur Beurteilung der Lärmeinwirkung auf Patienten. Im Foyer ist in jeder untersuchten Schicht die geistige Arbeit des Pflegepersonals nach den Vorgaben der Richtlinie VDI 2058 deutlich beeinträchtigt und die zulässige Grenze für überwiegend mechanisierte Tätigkeiten wird fast erreicht. Nach dem aktuellen Arbeitsrecht sind allerdings alle Vorgaben eingehalten, da lediglich ein Grenzwert zum Schutz vor Lärmschwerhörigkeit angegeben wird. Das Ausmaß des Lärms und der dadurch verursachte Stress, sowohl für Patienten als auch für das Pflegepersonal, zeigen den dringenden Bedarf nach gesetzlichen Regelungen auch in Deutschland. Investigations on noise nuisance of patients and nursing staff. The aim of this study was to assess the exposure to noise in intensive care units. Therefore, sound pressure level measurements have been carried out in both the sickroom and the ward corridor. A high noise exposure in the sickroom was found. In addition the measurement results proves that sleep disturbing noise is occurring at all hours. This high noise density has a dramatic impact on the patients' convalescence and recovery process. One for healthy patients "certain wake-up threshold" was defined, which is exceeded 5 times per hour also in the night. There is no regulation by the German law regarding the patients' exposure to noise in hospitals. While in the ward corridor the intellectual work of the nursing staff according to VDI 2058 is disturbed significantly in every shift investigated, the permissible guideline limit for mechanical works in this specific working environment is almost achieved. But the guidelines of the current labour law are always complied with, because there is only one limit for protection against noise induced hearing loss. The magnitude of noise and stress caused thereby, for both the patients and the nursing staff, show the urgent need of specific regulations by German law. [source] Anion exchange chromatography provides a robust, predictable process to ensure viral safety of biotechnology productsBIOTECHNOLOGY & BIOENGINEERING, Issue 1 2009Daniel M. Strauss Abstract The mammalian cell-lines used to produce biopharmaceutical products are known to produce endogenous retrovirus-like particles and have the potential to foster adventitious viruses as well. To ensure product safety and regulatory compliance, recovery processes must be capable of removing or inactivating any viral impurities or contaminants which may be present. Anion exchange chromatography (AEX) is a common process in the recovery of monoclonal antibody products and has been shown to be effective for viral removal. To further characterize the robustness of viral clearance by AEX with respect to process variations, we have investigated the ability of an AEX process to remove three model viruses using various combinations of mAb products, feedstock conductivities and compositions, equilibration buffers, and pooling criteria. Our data indicate that AEX provides complete or near-complete removal of all three model viruses over a wide range of process conditions, including those typically used in manufacturing processes. Furthermore, this process provides effective viral clearance for different mAb products, using a variety of feedstocks, equilibration buffers, and different pooling criteria. Viral clearance is observed to decrease when feedstocks with sufficiently high conductivities are used, and the limit at which the decrease occurs is dependent on the salt composition of the feedstock. These data illustrate the robust nature of the AEX recovery process for removal of viruses, and they indicate that proper design of AEX processes can ensure viral safety of mAb products. Biotechnol.
