ABSTRACT
Reconstitution of the adaptive immune system following allogeneic hematopoietic stem cell transplantation is crucial for beneficial outcome and is affected by several factors, such as GvHD and graft source. The impact of these factors on immune reconstitution has been thoroughly investigated during the early phase after transplantation. However, little is known about their long-term effect. Similarly, leukocyte telomere length (TL) shortening has been reported shortly after transplantation. Nevertheless, whether TL shortening continues in long-term aspect is still unsettled. Here, we assessed T-cell receptor excision circle (TREC), kappa deleting recombination excision circle (KREC) and leukocyte TL in recipients and donors several years post transplantation (median 17 years). Our analysis showed that, recipients who received bone marrow (BM) as the graft source have higher levels of both TREC and KREC. Also, chronic GvHD affected TREC levels and TL but not KREC levels. Finally, we show that recipient's TL was longer than respective donors in a group of young age recipients with high KREC levels. Our results suggest that BM can be beneficial for long-term adaptive immune recovery. We also present supporting evidence for recipient telomere homeostasis, especially in young age recipients, rather than telomere shortening.

AIM: The aim of this study was to coordinate the structured psychosocial, neurocognitive and educational follow-up of children treated for brain tumours with the medical protocol and apply the model in two Swedish healthcare regions. METHODS: We invited all children living in the two regions, who had been diagnosed with a brain tumour from October 1, 2010, through June 30, 2012, to participate along with their parents. The follow-up programme evaluated the emotional status of the parents and patients and assessed the children's general cognitive level, working memory, speed of performance, executive functions and academic achievement from diagnosis through to adult care. RESULTS: During the study period, 61 children up to the age of 17.1 years were diagnosed with a brain tumour, but 18 of these were excluded for various reasons. The majority of the mothers (70%) displayed significantly poor emotional status, as did 34% of the fathers and 21% of the children. The majority of the children (57%) also showed poor neurocognitive performance and needed special adaptations at school (66%). CONCLUSION: Our findings indicate the need for coordinated, multiprofessional follow-up programmes, well anchored in the healthcare organisation, for children diagnosed with brain tumours.

To assist in improving early interventions for psychosis, this study explored how adult people narrated their experience of becoming psychotic, and how contact with mental health personnel was established. Narrative interviews were conducted with 12 participants with psychotic illnesses recruited from acute psychiatric wards. The interviews were content analysed. Participants described being in a process of transition to psychosis as follows: experiencing changes as well-known signs of psychosis, experiencing sudden unexpected changes as signs of psychosis and experiencing unidentified changes as signs of illness. Our results show that participants and their close others who knew the signs of psychosis established a dialogue with mental health personnel and were better equipped to prevent and mitigate the psychosis. Our results demonstrate that participants who did not perceive the signs of psychosis and did not have other people to advocate for them were at risk for delayed treatment, poor communication and coercive interventions. Furthermore, participants who did not know the signs of psychosis perceived these changes as deterioration in their health and awareness of illness. We suggest that participants' experiential knowledge of transitioning to psychosis and an awareness of illness can be used to improve the communication during interventions for psychosis.

ABSTRACT
With the aim of assessing parental stress after SCT, 73 parents of children and adolescents who underwent SCT 5 or 10 years ago responded to questionnaires on general distress (General Health Questionnaire (GHQ)), disease-related stress (Pediatric Inventory for Parents-short form (PIP-SF)) and perceptions of child vulnerability (Child Vulnerability Scale (CVS)). General distress scores were comparable with the reference groups, but 40% of the mothers at 5 years after SCT reported increased stress levels as compared with 26% in the community-based reference group. Disease-related stress was comparable with the reference group of parents of children who were just off cancer treatment, 5 years after SCT. At 10 years after SCT, scores were lower than the reference group. Perceived child vulnerability did diminish over time, but remained high in parents of SCT survivors, compared with parents of healthy children: 96% of the parents at 5 years after SCT and 76% of the parents at 10 years after SCT scored above the cutoff point. Perceived vulnerability was found to be a predictor for parental disease-related stress. To conclude, although most parents of SCT survivors are resilient, the majority of parents perceive their child to be much more vulnerable as compared with parents of healthy children. This perception is associated with disease-related stress and may induce overprotective parenting.

AIM: To examine the prevalence of burnout symptoms in the context of parenting a chronically ill child. METHODS: A total of 252 parents of children with Type 1 Diabetes Mellitus and 38 parents of children with Inflammatory Bowel Diseases participated in a population-based study. A control group consisted of 124 randomly selected parents of healthy children. We used self-report questionnaires to assess symptoms of burnout. RESULTS: The main finding was that significantly more parents of children with chronic diseases (36%) scored for clinical burnout, compared with parents of healthy children (20%). Burnout symptoms were most prominent among mothers of children with diabetes, although fathers of children with diabetes and mothers and fathers of children with inflammatory bowel diseases also reported higher levels of various burnout symptoms. CONCLUSION: Burnout may be a useful model for understanding long-term parental responses and should be acknowledged among the different types of psychological consequences of the multi-faceted experience of parenting a child with chronic illness. Gender seems to influence the risk of burnout symptoms. Continued research about other background factors, and how the parents' situation changes over time are warranted. In the clinic, we need to draw attention to the group of parents who may suffer from burnout.

GOALS OF WORK: Pediatric stem cell transplantation (SCT) is a stressful treatment for children with relapsed or high-risk malignancies, immune deficiencies and certain blood diseases. Parents of children undergoing SCT can experience ongoing stress related to the SCT period. The aim of this article was to present a literature review of articles on parental distress and adaptation before, during, and after SCT and to identify risk and protective factors. MATERIALS AND METHODS: The review was conducted systematically by using PubMed, Web of Science, PsychInfo, and Picarta databases. Eighteen articles met our inclusion criteria: publishing date between January 1, 1990 and January 1, 2009; studies concerning parents of children undergoing SCT; studies examining the psychological adjustment and/or stress reactions of parents as primary outcomes and studies available in English. MAIN RESULTS: Highest levels of parental stress are reported in the period preceding SCT and during the acute phase. Stress levels decrease steadily after discharge in most parents. However, in a subgroup of parents, stress levels still remain elevated post-SCT. Parents most at risk in the longer term display highest levels of stress during the acute phase of the SCT. CONCLUSIONS: Psychosocial assessment before SCT, during the acute phase and in the longer term, is necessary to identify parents in need for support and follow-up care.

Despite a large number of studies reporting distress in parents after successfully completed cancer treatment of a child, few have explored the influence of current matters. The objective of this study was to explore parents' perceptions of post-treatment influence of childhood brain tumour. Semi-structured individual interviews were performed with the parents of seven children who had completed treatment for various types of brain tumour. Through inductive thematic analysis five key themes were derived, including 16 sub-themes. The key themes relate to: (1) survivor needs related to training and everyday life activities, where parents invested a large amount of time and commitment; (2) the everyday family life was restricted: family life in focus; (3) parenting role and routines had become more demanding; (4) for the parent as an individual daily routine as well as the view of life had changed; and (5) parental concerns and worries regarding the survivor's current and future well-being were amplified. Findings of the study suggest that the parents in the study struggle with the consequences of tangible strain, as well as existential challenges. Follow-up support should include updated information about the child's present state, and how it can be improved, as well as coaching when assisting and supporting the child.

The aim of this study is to illuminate the meaning of encounters with a troubled conscience among psychiatric therapists. Psychiatric care involves ethical dilemmas which may affect conscience. Conscience relates to keeping or losing a sense of personal integrity when making judgments about one's actions. Ten psychiatric therapists were interviewed in June 2006. The interviews were tape-recorded, transcribed verbatim and interpreted using a phenomenological-hermeneutic method. Two themes 'Facing inadequacy' and 'Struggling to view oneself as being 'good enough'' are presented. In the therapists interviewed, awareness of their use of power, a sense of powerlessness and a sense of blame gave rise to feelings of betrayals and shameful inadequacy. By sharing their inadequacy with co-workers, they managed to endure the sense of their inadequacy which otherwise would have threatened to paralyse them. Finding consolation in sharing wearing feelings, becoming realistic and attesting their worthiness, they reached reconciliation and found confirmation of being good enough. The findings are interpreted in light of Lögstrup's ethics of trust, according to which conscience alerts us to silent but radical ethical demand and the risk of self-deception.

Advances in the development of cross-coupling protocols that avoid haloaromatics are reviewed. Most of the reports that are discussed appeared in the literature within the past 2 years and describe either alternatives to halogenated electrophiles or halogen-free preparations of the organometallic partners. However, while this review is not limited to cross-couplings that are entirely free of haloaromatics, coverage of the topic is largely restricted to reactions affording new aryl-aryl, aryl-heteroaryl and heteroaryl-heteroaryl carbon-carbon bonds during the cross-coupling event.

Subunit interaction in sorbitol dehydrogenase (SDH) has been studied with in vitro and in silico methods identifying a vital hydrogen-bonding network, which is strictly conserved among mammalian SDH proteins. Mutation of one of the residues in the hydrogen-bonding network, Tyr110Phe, abolished the enzymatic activity and destabilized the protein into tetramers, dimers and monomers as judged from gel filtration experiments at different temperatures compared to only tetramers for the wild-type protein below 307 K. The determined equilibrium constants revealed a large difference in Gibbs energy (8 kJ/mol) for the tetramer stability between wild-type SDH and the mutated form Tyr110Phe SDH. The results focus on a network of coupled hydrogen bonds in wild-type SDH that uphold the protein interface, which is specific and favorable to electrostatic, van der Waals and hydrogen-bond interactions between subunits, interactions that are crucial for the catalytic power of SDH.

OBJECTIVE: To investigate glutamine kinetics during continuous renal replacement therapy (CRRT) in multiple organ failure (MOF) patients with and without exogenous intravenous glutamine supplementation. DESIGN AND PATIENTS: In a pragmatic clinical study 12 patients without urine production receiving CRRT were prospectively randomized in a cross-over design to receive glutamine intravenously for 20 h before placebo or placebo before glutamine on two consecutive days. Alanyl-glutamine or placebo (saline) was infused. MEASUREMENTS: Plasma glutamine concentration was measured in artery, femoral vein, and filtration fluid. Blood flow across the leg was measured and the efflux of glutamine calculated. The rate of appearance of glutamine was calculated from the plasma decay curve of glutamine concentration on the day of treatment. RESULTS: Glutamine supplementation increased plasma concentrations from 570+/-252 to 831+/-367 micromol l(-1). Glutamine losses into the filtration fluids were similar during treatment and control days: 25+/-13 vs. 24+/-11 mmol 24 h(-1), corresponding to 3.6+/-1.9 and 3.5+/-1.6 g 24 h(-1), respectively. Net glutamine balance across the leg was also similar on treatment and control days: 150+/-138 and 188+/-205 nmol min(-1) 100 ml(-1), respectively. The rate of appearance of glutamine was 54+/-17 g 24 h(-1). CONCLUSION: The loss of glutamine into the ultrafiltrate during CRRT in MOF patients suggests a greater need for exogenous glutamine than in patients without renal failure. The leg efflux and the filtration losses of glutamine were not affected in response to intravenous glutamine supplementation.

AIM: This paper reports a study examining factors that may contribute to burnout among healthcare personnel. BACKGROUND: The impact on burnout of factors such as workload and interpersonal conflicts is well-documented. However, although health care is a moral endeavour, little is known about the impact of moral strain. Interviews reveal that healthcare personnel experience a troubled conscience when they feel that they cannot provide the good care that they wish - and believe it is their duty - to give. METHODS: In this cross-sectional study, conducted in 2003, a sample of 423 healthcare personnel in Sweden completed a battery of questionnaires comprising the Maslach Burnout Inventory, Perception of Conscience Questionnaire, Stress of Conscience Questionnaire, Social Interactions Scale, Resilience Scale and a personal/work demographic form. RESULTS: Regression analysis resulted in a model that explained approximately 59% of the total variation in emotional exhaustion. Factors associated with emotional exhaustion were 'having to deaden one's conscience', and 'stress of conscience' from lacking the time to provide the care needed, work being so demanding that it influences one's home life, and not being able to live up to others' expectations. Several additional variables were associated with emotional exhaustion. Factors contributing to depersonalization were 'having to deaden one's conscience', 'stress of conscience' from not being able to live up to others' expectations and from having to lower one's aspirations to provide good care, deficient social support from co-workers, and being a physician; however, the percentage of variation explained was smaller (30%). CONCLUSION: Being attentive to our own and others' feelings of troubled conscience is important in preventing burnout in health care, and staff need opportunities to reflect on their troubled conscience. Further research is needed into how a troubled conscience can be eased, particularly focusing on the working environment.

A survey was carried out in a hospital of Nova Iguaçu, Rio de Janeiro, Brazil, in the period from July 1999 to March 2002, to determine the infection rate of Listeria monocytogenes in HIV+ patients with diarrhea symptoms; 134 samples were processed by microbiological methods. The results demonstrated 12.68% of positive samples. However, no statistical differences were observed for age or sex in the studied group, suggesting that this microorganism should be regarded in the differential diagnosis of infectious processes in HIV+ patients in the area

Research on nurses' responses to suicidal patients is sparse. The purpose of this secondary analysis of qualitative data from interviews with 19 nurses employed in Norway was to describe nurses' responses to suicidal psychiatric inpatients. Thematic analyses revealed four themes: 'struggling with discernment of self and sufferer'; 'reconciling inner dialogue'; 'opening up while envisioning self from sufferer'; and 'revisioning the meaning of life revealed over time'. The main theme was 'struggling with self and sufferer'. While these findings reveal existential issues and self reflections of psychiatric nurses' struggle with the suffering of suicidal patients, they also contribute to a methodological debate. Further research is needed to examine nurses' responses to suicidal patients in various settings and to develop secondary analysis of qualitative data.

A randomised, double blind, placebo-controlled study was performed giving 0.5 g x kg(-1) x day(-1) of undiluted alanyl-glutamine (20%) or saline in a peripheral vein during 4 hours in ICU patients (n = 20). During the infusion period a steady state in plasma concentration was reached for alanyl-glutamine, but not for alanine, glutamine or glutamate. On the other hand there was no accumulation of any of the amino acids, as the pre-infusion concentrations were reached within 8 hours after the end of infusion. The half-life of the dipeptide was 0.26 hours (range, 0.15-0.63 h). The distribution volume of alanyl-glutamine was larger than the extracellular water volume, indicating a rapid hydrolysis of the dipeptide. There was no detectable alanyl-glutamine in the urine of any of the patients. All patients had excretion of small amounts of amino acids in urine, but the renal clearance of alanine, glutamine and glutamate were not different between the two groups.

Different concepts have been presented which denote driving forces and strengths that contribute to a person's ability to meet and handle adversities, and keep or regain health. The aim of this study, which is a part of The Umeå 85+ study, was to describe resilience, sense of coherence, purpose in life and self-transcendence in relation to perceived physical and mental health in a sample of the oldest old. The study sample consisted of 125 participants 85 years of age or older, who ranked themselves on the Resilience Scale, Sense of Coherence Scale, Purpose in Life Scale and Self-Transcendence Scale and answered the SF-36 Health Survey questionnaire. The findings showed significant correlations between scores on the Resilience Scale, the Sense of Coherence Scale, the Purpose in Life Test, and the Self-Transcendence Scale. Significant correlations were also found between these scales and the SF-36 Mental Health Summary among women but not among men. There was no significant correlation between perceived physical and mental health. The mean values of the different scales showed that the oldest old have the same or higher scores than younger age groups. Regression analyses also revealed sex differences regarding mental health. The conclusions are that, the correlation between scores on the different scales suggests that the scales measure some dimension of inner strength and that the oldest old have this strength at least in the same extent as younger adults. Another conclusion is that the dimensions that constitute mental health differ between women and men.

The frequency of envenoming in Northwest counties of the Rio de Janeiro State, Brazil, from 1995 to 2000 was evaluated. Reports from the Municipal Secretariat of Health of these counties were used. The results demonstrated that, from 1997 to 1999, there was a shortage of notification, and 40 cases of envenomations caused by Bothrops snakes were registered. These cases were more common from February to October, and the lower limbs of male peasants were the mainly affected areas.(AU)

The prevalence and clinical forms of Trypanosoma cruzi were evaluated among blood donor candidates attended at a general hospital in Rio de Janeiro, Brazil, from January 1997 to April 1999. The investigation was done by means of the indirect hemagglutination test and was confirmed via ELISA. Data were collected from clinical examinations, conventional electrocardiogram, chest radiography and echocardiography. The results showed that despite Trypanosoma cruzi prevalence of 1.17% (128 patients), mainly in males aged 40 years or over, 70.8% of these patients, mainly males aged 19 to 39 years, demonstrated abnormalities that allowed the diagnosis of cardiopathy and/or esophagopathy. This once again corroborates the importance of Trypanosoma cruzi infection in urban centers.
