Effects of nasal continuous airway pressure on pulmonary and systemic output in preterm infants

Objective: Respiratory assistance with nasal continuous positive airway pressure (n-CPAP) is an effective treatment in premature newborns presenting respiratory distress. The aim of the study was to depict cardiac function, systemic (Qs) and pulmonary output (Qp) by echocardiography in stable premature infants requiring prolonged n-CPAP. Our hypothesis was that n-CPAP could reduce pulmonary blood flow. Patients and methods: All premature infants < 32 weeks gestation, > 7 days-old, requiring n-CPAP without severe respiratory compromise nor need for additional oxygen were prospectively included. Every patient had a first echocardiography while on n-CPAP. N-CPAP was then discontinued for two hours and a second echocardiography was performed. Results: 17 premature infants were included. Mean gestational age was 28 ± 2 weeks and mean weight 1.1 ± 0.3 kg. Following retrieval of n-CPAP we observed an increase in Qp of 53 ml/kg/min (95% CI 19-87 ml/kg/min), but no significant change in Qs. Consecutively a significant increase in Qp/Qs ratio of 16% was found (95% CI 7-29%). Conclusions: Nasal continuous positive airway pressure has hemodynamic effects in preterm infants in stable pulmonary and cardiac conditions. It reduces pulmonary output without interference with systemic output.

A prospective, randomized, and controlled study of fluid management in children with severe head injury: lactated Ringer's solution versus hypertonic saline.

OBJECTIVES: Resuscitation in severe head injury may be detrimental when given with hypotonic fluids. We evaluated the effects of lactated Ringer's solution (sodium 131 mmol/L, 277 mOsm/L) compared with hypertonic saline (sodium 268 mmol/L, 598 mOsm/L) in severely head-injured children over the first 3 days after injury. DESIGN: An open, randomized, and prospective study. SETTING: A 16-bed pediatric intensive care unit (ICU) (level III) at a university children's hospital. PATIENTS: A total of 35 consecutive children with head injury. INTERVENTIONS: Thirty-two children with Glasgow Coma Scores of <8 were randomly assigned to receive either lactated Ringer's solution (group 1) or hypertonic saline (group 2). Routine care was standardized, and included the following: head positioning at 30 degrees; normothermia (96.8 degrees to 98.6 degrees F [36 degrees to 37 degrees C]); analgesia and sedation with morphine (10 to 30 microg/kg/hr), midazolam (0.2 to 0.3 mg/kg/hr), and phenobarbital; volume-controlled ventilation (PaCO2 of 26.3 to 30 torr [3.5 to 4 kPa]); and optimal oxygenation (PaO2 of 90 to 105 torr [12 to 14 kPa], oxygen saturation of >92%, and hematocrit of >0.30). MEASUREMENTS AND MAIN RESULTS: Mean arterial pressure and intracranial pressure (ICP) were monitored continuously and documented hourly and at every intervention. The means of every 4-hr period were calculated and serum sodium concentrations were measured at the same time. An ICP of 15 mm Hg was treated with a predefined sequence of interventions, and complications were documented. There was no difference with respect to age, male/female ratio, or initial Glasgow Coma Score. In both groups, there was an inverse correlation between serum sodium concentration and ICP (group 1: r = -.13, r2 = .02, p < .03; group 2: r = -.29, r2 = .08, p < .001) that disappeared in group 1 and increased in group 2 (group 1: r = -.08, r2 = .01, NS; group 2: r = -.35, r2 =.12, p < .001). Correlation between serum sodium concentration and cerebral perfusion pressure (CPP) became significant in group 2 after 8 hrs of treatment (r = .2, r2 = .04, p = .002). Over time, ICP and CPP did not significantly differ between the groups. However, to keep ICP at <15 mm Hg, group 2 patients required significantly fewer interventions (p < .02). Group 1 patients received less sodium (8.0 +/- 4.5 vs. 11.5 +/- 5.0 mmol/kg/day, p = .05) and more fluid on day 1 (2850 +/- 1480 vs. 2180 +/- 770 mL/m2, p = .05). They also had a higher frequency of acute respiratory distress syndrome (four vs. 0 patients, p = .1) and more than two complications (six vs. 1 patient, p = .09). Group 2 patients had significantly shorter ICU stay times (11.6 +/- 6.1 vs. 8.0 +/- 2.4 days; p = .04) and shorter mechanical ventilation times (9.5 +/- 6.0 vs. 6.9 +/- 2.2 days; p = .1). The survival rate and duration of hospital stay were similar in both groups. CONCLUSIONS: Treatment of severe head injury with hypertonic saline is superior to that treatment with lactated Ringer's solution. An increase in serum sodium concentrations significantly correlates with lower ICP and higher CPP. Children treated with hypertonic saline require fewer interventions, have fewer complications, and stay a shorter time in the ICU.

Propionic acidemia: clinical course and outcome in 55 pediatric and adolescent patients.

BACKGROUND: Propionic acidemia is an inherited disorder caused by deficiency of propionyl-CoA carboxylase. Although it is one of the most frequent organic acidurias, information on the outcome of affected individuals is still limited. STUDY DESIGN/METHODS: Clinical and outcome data of 55 patients with propionic acidemia from 16 European metabolic centers were evaluated retrospectively. 35 patients were diagnosed by selective metabolic screening while 20 patients were identified by newborn screening. Endocrine parameters and bone age were evaluated. In addition, IQ testing was performed and the patients' and their families' quality of life was assessed. RESULTS: The vast majority of patients (>85%) presented with metabolic decompensation in the neonatal period. Asymptomatic individuals were the exception. About three quarters of the study population was mentally retarded, median IQ was 55. Apart from neurologic symptoms, complications comprised hematologic abnormalities, cardiac diseases, feeding problems and impaired growth. Most patients considered their quality of life high. However, according to the parents' point of view psychic problems were four times more common in propionic acidemia patients than in healthy controls. CONCLUSION: Our data show that the outcome of propionic acidemia is still unfavourable, in spite of improved clinical management. Many patients develop long-term complications affecting different organ systems. Impairment of neurocognitive development is of special concern. Nevertheless, self-assessment of quality of life of the patients and their parents yielded rather positive results.

Traumatismes précoces et réponses de stress, leur association aves la santé mentale, l'attachement et l'ocytocine

Lorsqu'un individu est confronté à une situation stressante, une des réponses les plus saillantes est l'activation de l'axe HPA, caractérisée par le déclenchement d'un taux élevé de glucocorticoïdes dans le sang. De manière générale, cette réponse hormonale est adaptative et elle a pour but la mobilisation des ressources physiques et cognitives de l'individu pour une action spécifique (Axelrod & Reisine, 1984; Chrousos & Gold, 1992; N. M. Kaplan, 1988; McEwen, 2004). Cependant, lorsque une personne est confrontée très tôt dans son développement, et de manière répétée, à des situations de stress, cette réponse physiologique peut s'altérer, devenir inadaptée (Anand, 1993; Bremner et al., 1995; Meaney et al., 1996; Mirescu, Peters, & Gould, 2004; Plotsky & Meaney, 1993; Sapolsky, 2000) et être associée à des troubles cognitifs (McEwen & Sapolsky, 1995) et émotionnels (McEwen, 2000). A l'âge adulte, le résultat de ces altérations psychoneuroendocriniennes se traduit au cours de l'activation de l'axe HPA et elles sont visibles lors de situations de stress moins intenses (Graham, Heim, Goodman, Miller, & Nemeroff, 1999; Mirescu et al., 2004; Stam, Bruijnzeel, & Wiegant, 2000; A. Taylor, Fisk, & Glover, 2000). La dysregulation de l'axe HPA semble représenter un facteur de vulnérabilité lié à des dysfonctionnements psychiques et physiologiques chez les adultes (Heim, Ehlert, & Hellhammer, 2000; Heim & Nemeroff, 1999; Heim, Newport, Mletzko, Miller, & Hemeroff, 2008). Cependant, des facteurs de protection peuvent influencer à leur tour ces vulnérabilités. La littérature, basée sur des études translationnelles (animaux, humains), converge vers le postulat selon lequel la dimension relationnelle apportée par l'environnement est fondamentale dans le développement des vulnérabilités physiologiques et psychiques du sujet. Dans ce sens, les relations d'attachement ont été particulièrement étudiées. A l'âge adulte, par exemple, la qualité des représentations d'attachement semble influencer directement l'expression de gènes impliqués dans les réponses hormonales de stress (Biagini, Pich, Carani, Marrama, & Agnati, 1998; Caldji, Diorio, & Meaney, 2000; Dallman, 2000; De Kloet, Rosenfeld, Van Eekelen, Sutanto, & Levine, 1988; Rincon-Cortes & Sullivan, 2014; Romeo, Tang, & Sullivan, 2009; van Oers, de Kloet, Whelan, & Levine, 1998), illustrant ainsi une perspective épigénétique. Traumatismes précoces et réponses de stress, leur association avec la santé mentale, l'attachement et l'ocytocine Deux objectifs principaux définissent ce travail de doctorat. Le premier est de comprendre comment un événement à portée traumatique, qui a eu lieu pendant la période périnatale, l'enfance ou l'adolescence, peut s'inscrire au niveau physiologique (axe hypotalamico- hypophysaire-surrénalien - axe HPA), au niveau psychopathologique ou encore au niveau de la régulation émotionnelle au cours de l'âge adulte. A ce propos, nous avons évalué les réponses physiologiques (telles que le Cortisol, l'ACTH et l'ocytocine), la présence de psychopathologies (relatives à l'axe I du DSM-IV) et les réponses émotionnelles (telles que la perception au stress) au cours d'une situation de stress de nature psychosociale, induite en laboratoire. Le deuxième objectif de ce travail est de savoir si les représentations d'attachement peuvent médiatiser ces effets, chez des individus exposés à différents événements à portée traumatique. Dans ce but, trois populations ont été considérées. La première est relative à des jeunes adultes nés grands prématurés ; la deuxième, concerne des femmes adultes ayant vécu un ou plusieurs abus sexuels au cours de leur enfance ou de leur adolescence et enfin la troisième est constituée de personnes adultes qui ont survécu à une maladie grave (cancer) pendant leur enfance ou leur adolescence. Enfin, ces trois populations sont comparées à des groupes contrôle. La prise en considération de différents types de traumatismes a permis de relever : premièrement, qu'un événement à portée traumatique de nature différente, peut influencer de manière semblable les structures neuronales, par exemple l'hypocortisolémie ; deuxièmement, qu'un dysfonctionnement de l'axe HPA n'aboutit pas nécessairement à la présence de signes de souffrance mentale ; enfin, des effets protecteurs ont été mis en évidence. Ces facteurs sont sous-tendus, d'un point de vue psychologique, par les représentations d'attachement et, d'un point de vue physiologique, par la sécrétion d'ocytocjne périphérique. Traumatismes précoces et réponses de stress, leur association avec la santé mentale, l'attachement et l'ocytocine -- When an individual is faced by a stressful situation, one of the most notable responses is the activation of the HPA axis, which is characterized by a heightened level of glucocortisoids in the blood. In general, this is an adaptive hormonal response which prepares the individual both physically and cognitively for a specific action (Axelrod & Reisine, 1984; Chrousos & Gold, 1992; N. M. Kaplan, 1988; McEwen, 2004). However, should a person be confronted to stressful situations very early and repeatedly in their development, this physiologic response may be altered and become maladapted (Anand, 1993; Bremner et al., 1995; Meaney et al., 1996; Mirescu et al., 2004; Plotsky & Meaney, 1993; Sapolsky, 2000) which can be associated to emotional (McEwen, 2000) and cognitive disorders(McEwen & Sapolsky, 1995). Throughout adulthood, the result of these psychoneuroendocrine alterations affects the activation of the HPA axis and are noticeable during less intense stressful situations (Graham et al., 1999; Mirescu et al., 2004; Stam et al., 2000; A. Taylor et al., 2000). HPA axis dysregulation appears to represent a factor of vulnerability linked to psychological and physical disorders in adults (Heim, Ehlert, et al., 2000; Heim & Nemeroff, 1999; Heim, Newport, et al., 2008). Nonetheless, these vulnerabilities may be influenced by further protection factors. The literature, based on translational studies (animals and humans), suggests that relationships formed in the context of the individual's environment are fundamental in the development of their physiological and psychological vulnerabilities. Thus, attachment relationships have been particularly studied. In adulthood, for example, the quality of attachment representations appear to influence directly the expression of genes involved in the hormonal responses to stress (Biagini et al., 1998; Caldji et al., 2000; Dallman, 2000; De Kloet et al., 1988; Rincon-Cortes & Sullivan, 2014; Romeo et al., 2009; van Oers et al., 1998). With the goal to study these dimensions, two principal objectives define these doctoral study. The first is to understand how an event considered to be traumatic, which took place during early infancy, infancy, or adolescence, could influence physiology (HPA axis), psychopathology or emotional regulation during adulthood. Therefore we have evaluated the presence of psychopathologies (relative to axis I of the DSM), physiological responses (such as Cortisol, ACTH and oxytocin) and emotional responses (such as perception of stress) throughout a psychosocial stress situation, conducted in a laboratory setting. The second objective of this study is to understand if attachment representations can mediate these effects, in individuals exposed to three different types of traumatic events. Therefore, three populations have been considered. The first is young adults who were born prematurely; the second concerns adult women who have suffered sexual abuse, on one or more occasions, during their childhood or adolescence; finally the third group is constituted of people who have survived a grave childhood illness. These populations were all compared to control groups. The consideration of different types of traumatic events has demonstrated, firstly, that different events which are considered to be traumatic can similarly influence neuronal structures, for example hypocortisolism. Secondly, that an HPA axis disorder does not necessarily lead to the presence of mental signs of distress, as is the case for those born very prematurely. Finally, protective effects were demonstrated, distinctively from a psychological point of view, by attachment representations and furthermore by peripheral oxytocin secretion from a physiological perspective.

Expert clinical reasoning and pain assessment in mechanically ventilated patients: A descriptive study.

BACKGROUND: Pain assessment in mechanically ventilated patients is challenging, because nurses need to decode pain behaviour, interpret pain scores, and make appropriate decisions. This clinical reasoning process is inherent to advanced nursing practice, but is poorly understood. A better understanding of this process could contribute to improved pain assessment and management. OBJECTIVE: This study aimed to describe the indicators that influence expert nurses' clinical reasoning when assessing pain in critically ill nonverbal patients. METHODS: This descriptive observational study was conducted in the adult intensive care unit (ICU) of a tertiary referral hospital in Western Switzerland. A purposive sample of expert nurses, caring for nonverbal ventilated patients who received sedation and analgesia, were invited to participate in the study. Data were collected in "real life" using recorded think-aloud combined with direct non-participant observation and brief interviews. Data were analysed using deductive and inductive content analyses using a theoretical framework related to clinical reasoning and pain. RESULTS: Seven expert nurses with an average of 7.85 (±3.1) years of critical care experience participated in the study. The patients had respiratory distress (n=2), cardiac arrest (n=2), sub-arachnoid bleeding (n=1), and multi-trauma (n=2). A total of 1344 quotes in five categories were identified. Patients' physiological stability was the principal indicator for making decision in relation to pain management. Results also showed that it is a permanent challenge for nurses to discriminate situations requiring sedation from situations requiring analgesia. Expert nurses mainly used working knowledge and patterns to anticipate and prevent pain. CONCLUSIONS: Patient's clinical condition is important for making decision about pain in critically ill nonverbal patients. The concept of pain cannot be assessed in isolation and its assessment should take the patient's clinical stability and sedation into account. Further research is warranted to confirm these results.

Congenital tracheal anomalies.

Congenital tracheal lesions are rare, but important, causes of morbidity in infants and children. Consequently, experience in their management is limited and dispersed. Given its small diameter, the juvenile trachea is obstructed easily by various natural causes, or following a surgical intervention. The diagnosis of a congenital, tracheal, obstructive anomaly is based on a high degree of suspicion in infants and children with respiratory distress accompanied by retraction. In this article, the authors discuss the various causes of these conditions, their diagnostic features, and the treatment possibilities.

Psychosexual development in men with congenital hypogonadotropic hypogonadism on long-term treatment: a mixed methods study.

INTRODUCTION: Congenital hypogonadotropic hypogonadism (CHH) is a rare, genetic, reproductive endocrine disorder characterized by absent puberty and infertility. Limited information is available on the psychosocial impact of CHH and psychosexual development in these patients. AIM: The aim of this study was to determine the impact of CHH on psychosexual development in men on long-term treatment. METHODS: A sequential mixed methods explanatory design was used. First, an online survey (quantitative) was used to quantify the frequency of psychosexual problems among CHH men. Second, patient focus groups (qualitative) were conducted to explore survey findings in detail and develop a working model to guide potential nursing and interdisciplinary interventions. MAIN OUTCOME MEASURES: Patient characteristics, frequency of body shame, difficulty with intimate relationships, and never having been sexually active were assessed. Additionally, we collected subjective patient-reported outcomes regarding the impact of CHH on psychological/emotional well-being, intimate relationships, and sexual activity. RESULTS: A total of 101 CHH men on long-term treatment (>1 year) were included for the analysis of the online survey (mean age 37 ± 11 years, range 19-66, median 36). Half (52/101, 51%) of the men had been seen at a specialized academic center and 37/101 (37%) reported having had fertility-inducing treatment. A high percentage of CHH men experience psychosexual problems including difficulty with intimate relationships (70%) and body image concerns/body shame (94/101, 93%), and the percentage of men never having been sexually active is five times the rate in a reference group (26% vs. 5.4%, P < 0.001). Focus groups revealed persisting body shame and low self-esteem despite long-term treatment that has lasting impact on psychosexual functioning. CONCLUSIONS: CHH men frequently experience psychosexual problems that pose barriers to intimate relationships and initiating sexual activity. These lingering effects cause significant distress and are not ameliorated by long-term treatment. Psychosexual assessment in CHH men with appropriate psychological support and treatment should be warranted in these patients. Dwyer AA, Quinton R, Pitteloud N, and Morin D.

Mise en récit et théâtralisation dans le jeu en psychothérapie d'enfants : de l'archaïque au symbolique

« Il était une fois... Cette thèse aborde le lien entre l'expression théâtrale et son utilisation clinique dans la psychothérapie d'enfants. Partant du questionnement sur les origines du théâtre et de la thérapie dans l'histoire de l'humanité, donc du substrat « archaïque » de l'homme et de sa relation à l'art scénique, la première partie développe une réflexion autour des rituels, du chamanisme et de la notion du soin. Purement théorique, elle soulève cependant la question de l'identité de l'Homme dans les sociétés postmodernes et traite de la thématique du développement psychique de l'enfant au sein de notre société occidentale ainsi que des souffrances qui en amènent certains vers les consultations psychologiques La partie principale s'articule autour de six histoires cliniques d'enfants suivis en psychothérapie expressive, récits dans lesquels la médiation théâtrale et corporelle devient 1 outil central du soin. En se développant sur la base d'une mise en narration des histoires imaginaires des enfants qui reflètent leurs angoisses archaïques, 1 univers thérapeutique prend alors la forme d'une scène psychique ouvrant a la symbolisation à travers le jeu théâtral. Parallèlement à la description de ce dispositif, une élaboration est menée autour des échanges transférentiels et con re transferentiels ainsi que sur la position du thérapeute - son rôle de « médium malleable » - dans la relation à l'Autre qui se tisse dans un « ici et maintenant » de la rencontre psychotherapeutic. Grâce à cet univers ludique s'enracinant dans son vécu psycho-fantasmatique, l'enfant devient l'acteur agissant de sa propre transfonnation : une évolution du monstre archaïque en sa créature symbolique. -- « Once upon a time... » This thesis treats the link between theatrical expression and its clinical use in children s psychotherapy. Originating from interrogations on the origins of theatre and therapy in the history of mankind, therefore the « archaic » substratum of Man and his relation to the theatre. The first part develops a reflection around rituals shamanism and the notion of care. In a purely theoretical way, it brings up the ques ions of Man's identity in post-modern societies and deals with the psychic development of children in western society and the pains that lead some to seek for psychological consultations. The main part hinges on six clinical stories of children in expressive psychotherapy, m which theatrical and coiporal mediation become the main tool within he treatment. By putting into narration, the children's imaginary stories that reflect their archaic anxiety, therapy takes in the shape of a psychic scene, which opens to symbolization through acting. At the same time, an elaboration is lead on transferential and counter-transferential exchanges as on the therapists position - his role as « malleable medium » - his interactions with others as a «here and now » in the psychotherapeutic encounter. Thanks to this playful universe, which emerges from his psycho-fantasy past, the child becomes the willing actor of his own transformation: the evolution of the archaic monster into its symbolical creature.

Validity of the FACIT-Sp to assess spiritual well-being in elderly patients

Among instruments measuring spiritual well-being, the Functional Assessment of Chronic Illness Therapy-Spiritual well-being (FACIT-Sp-12) is the most widely used instrument in research. It has been validated in patients suffering from cancer or HIV/AIDS, but has rarely been used in elderly patients. The objectives of this study were to determine the psychometric properties and suitability of the FACIT-Spto assess spiritual well-being in hospitalized elderly patients. This cross-sectional study uses a mixed method approach. Subjects were patients (N = 208), aged 65 years and older, consecutively admitted in post-acute rehabilitation. Psychometric properties of the FACITSp were investigated. The internal structure of the FACIT-Sp (factor structure and internal consistency) was assessed. Convergent validity of the FACIT-Sp was assessed using the Spiritual Distress Assessment Tool (SDAT), the question "Are you at peace?" and the Geriatric Depression Scale (GDS). Predictive validity was assessed using length of stay (LOS) and discharge destination. Understanding and interpretation of FACIT-Sp items were consecutively assessed in a sub-sample of 135 patients. Results show that FACIT-Sp scores ranged from 7 to 46 (mean 29.6 ± 7.8); 23.1% of the patients had high spiritual well-being. Cronbach's α was g ood ( 0.85). Item-to-total correlations were all significant (0.34 to 0.73). Principal component analyses performed with 2 or 3 factors were only moderately consistent with previous work. FACIT-Sp correlated with SDAT, "Are you at peace?" and GDS (Rho = −0.45, P < 0.001; 0.51, P < 0.001 and −0.38, P < 0.001). No association was found with LOS or discharge destination. Spontaneous comments about one or more FACIT-Sp items were made by 97/135 (71.9%). Specifically, items that address purpose and meaning in life were frequently found difficult to answer. Analyses suggest that the FACIT-Sp may underestimate spiritual well-being in older patients. In conclusion, despite having acceptable psychometric properties, the FACIT-Sp presents limitations for measurement of spiritual well-being in hospitalized elderly patients.

Psychotherapy for Personality Disorders in a Natural Setting: A Pilot Study over Two Years of Treatment.

Long-term assessment of the effects of psychotherapy for personality disorders (PDs) in a natural environment is an important task. Such research contributes to enlarge the practice-based evidence, embedded in broad collaborations between clinicians and researchers in psychotherapy for PDs. The present pilot study used rigorous assessment procedures and incorporated feedback loops of outcome information to the therapists in demonstrating the effects of psychotherapy for PD in a natural setting. The number of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), criteria for any PD was the primary outcome (along with psychological distress, depression, impulsiveness, and quality of life as secondary measures), assessed at intake, 6, 12, 18, and 24 months of psychotherapy for N = 13 patients with PD. Data were analyzed using hierarchical linear modeling. Results demonstrated a large pre-post effect (d = 2.22) for the observer-rated measure (primary outcome), and small to medium effects for the secondary outcomes; these results were corroborated by a steady decrease of symptoms over all five time points, which was significant for several outcomes. These results add a piece to the literature by demonstrating the effects of long-term psychotherapy for PDs in increasingly diverse contexts and suggest that practice-oriented research can be carried out in a collaborative and systematic manner.

High rates of smoking especially in female Crohn's disease patients and low use of supportive measures to achieve smoking cessation : Data from the SwissIBD cohort study

BACKGROUND AND AIMS: Smoking is a crucial environmental factor in inflammatory bowel disease (IBD). However, knowledge on patient characteristics associated with smoking, time trends of smoking rates, gender differences and supportive measures to cease smoking provided by physicians is scarce. We aimed to address these questions in Swiss IBD patients. METHODS: Prospectively obtained data from patients participating in the Swiss IBD cohort study was analysed and compared to the general Swiss population (GSP) matched by age, sex and year. RESULTS: Among a total of 1770 IBD patients analysed (49.1% male), 29% are current smokers. More than twice as many patients with Crohn's disease (CD) are active smokers compared to ulcerative colitis (UC, 39.6% vs. 15.3%, p<0.001). In striking contrast to the GSP, significantly more women than men with CD smoke (42.8% vs. 35.8%, p=0.025), with also an overall significantly increased smoking rate compared to the GSP in women but not men. The vast majority of smoking IBD patients (90.5%) claim to never have received any support to achieve smoking cessation, significantly more in UC compared to CD. We identify a significantly negative association of smoking and primary sclerosing cholangitis, indicative of a protective effect. Psychological distress in CD is significantly higher in smokers compared to non-smokers, but does not differ in UC CONCLUSIONS: Despite well-established detrimental effects, smoking rates in CD are alarmingly high with persistent and stagnating elevations compared to the GSP, especially in female patients. Importantly, there appears to be an unacceptable underuse of supportive measures to achieve smoking cessation.

Responding to Young People's Health Risks in Primary Care: A Cluster Randomised Trial of Training Clinicians in Screening and Motivational Interviewing.

OBJECTIVE: To evaluate the effectiveness of a complex intervention implementing best practice guidelines recommending clinicians screen and counsel young people across multiple psychosocial risk factors, on clinicians' detection of health risks and patients' risk taking behaviour, compared to a didactic seminar on young people's health. DESIGN: Pragmatic cluster randomised trial where volunteer general practices were stratified by postcode advantage or disadvantage score and billing type (private, free national health, community health centre), then randomised into either intervention or comparison arms using a computer generated random sequence. Three months post-intervention, patients were recruited from all practices post-consultation for a Computer Assisted Telephone Interview and followed up three and 12 months later. Researchers recruiting, consenting and interviewing patients and patients themselves were masked to allocation status; clinicians were not. SETTING: General practices in metropolitan and rural Victoria, Australia. PARTICIPANTS: General practices with at least one interested clinician (general practitioner or nurse) and their 14-24 year old patients. INTERVENTION: This complex intervention was designed using evidence based practice in learning and change in clinician behaviour and general practice systems, and included best practice approaches to motivating change in adolescent risk taking behaviours. The intervention involved training clinicians (nine hours) in health risk screening, use of a screening tool and motivational interviewing; training all practice staff (receptionists and clinicians) in engaging youth; provision of feedback to clinicians of patients' risk data; and two practice visits to support new screening and referral resources. Comparison clinicians received one didactic educational seminar (three hours) on engaging youth and health risk screening. OUTCOME MEASURES: Primary outcomes were patient report of (1) clinician detection of at least one of six health risk behaviours (tobacco, alcohol and illicit drug use, risks for sexually transmitted infection, STI, unplanned pregnancy, and road risks); and (2) change in one or more of the six health risk behaviours, at three months or at 12 months. Secondary outcomes were likelihood of future visits, trust in the clinician after exit interview, clinician detection of emotional distress and fear and abuse in relationships, and emotional distress at three and 12 months. Patient acceptability of the screening tool was also described for the intervention arm. Analyses were adjusted for practice location and billing type, patients' sex, age, and recruitment method, and past health risks, where appropriate. An intention to treat analysis approach was used, which included multilevel multiple imputation for missing outcome data. RESULTS: 42 practices were randomly allocated to intervention or comparison arms. Two intervention practices withdrew post allocation, prior to training, leaving 19 intervention (53 clinicians, 377 patients) and 21 comparison (79 clinicians, 524 patients) practices. 69% of patients in both intervention (260) and comparison (360) arms completed the 12 month follow-up. Intervention clinicians discussed more health risks per patient (59.7%) than comparison clinicians (52.7%) and thus were more likely to detect a higher proportion of young people with at least one of the six health risk behaviours (38.4% vs 26.7%, risk difference [RD] 11.6%, Confidence Interval [CI] 2.93% to 20.3%; adjusted odds ratio [OR] 1.7, CI 1.1 to 2.5). Patients reported less illicit drug use (RD -6.0, CI -11 to -1.2; OR 0·52, CI 0·28 to 0·96), and less risk for STI (RD -5.4, CI -11 to 0.2; OR 0·66, CI 0·46 to 0·96) at three months in the intervention relative to the comparison arm, and for unplanned pregnancy at 12 months (RD -4.4; CI -8.7 to -0.1; OR 0·40, CI 0·20 to 0·80). No differences were detected between arms on other health risks. There were no differences on secondary outcomes, apart from a greater detection of abuse (OR 13.8, CI 1.71 to 111). There were no reports of harmful events and intervention arm youth had high acceptance of the screening tool. CONCLUSIONS: A complex intervention, compared to a simple educational seminar for practices, improved detection of health risk behaviours in young people. Impact on health outcomes was inconclusive. Technology enabling more efficient, systematic health-risk screening may allow providers to target counselling toward higher risk individuals. Further trials require more power to confirm health benefits. TRIAL REGISTRATION: ISRCTN.com ISRCTN16059206.

Stress oxydant chez l'enfant prématuré : causes, biomarqueurs et possibilités thérapeutiques [Oxidative stress after preterm birth: Origins, biomarkers, and possible therapeutic approaches].

The survival of preterm babies has increased over the last few decades. However, disorders associated with preterm birth, known as oxygen radical diseases of neonatology, such as retinopathy, bronchopulmonary dysplasia, periventricular leukomalacia, and necrotizing enterocolitis are severe complications related to oxidative stress, which can be defined by an imbalance between oxidative reactive species production and antioxidant defenses. Oxidative stress causes lipid, protein, and DNA damage. Preterm infants have decreased antioxidant defenses in response to oxidative challenges, because the physiologic increase of antioxidant capacity occurs at the end of gestation in preparation for the transition to extrauterine life. Therefore, preterm infants are more sensitive to neonatal oxidative stress, notably when supplemental oxygen is being delivered. Furthermore, despite recent advances in the management of neonatal respiratory distress syndrome, controversies persist concerning the oxygenation saturation targets that should be used in caring for preterm babies. Identification of adequate biomarkers of oxidative stress in preterm infants such as 8-iso-prostaglandin F2α, and adduction of malondialdehyde to hemoglobin is important to promote specific therapeutic approaches. At present, no therapeutic strategy has been validated as prevention or treatment against oxidative stress. Breastfeeding should be considered as the main measure to improve the antioxidant status of preterm infants. In the last few years, melatonin has emerged as a protective molecule against oxidative stress, with antioxidant and free-radical scavenger roles, in experimental and preliminary human studies, giving hope that it can be used in preterm infants in the near future.

Expressive writing intervention for mothers following the birth of their premature baby.

The birth of a preterm infant is in most cases unexpected and can be a distressing experience for parents. Parents of premature babies report more stress, experience more adjustment difficulties and need for support during the first year after delivery compared to parents of infants born at term. It has been documented that parents may experience posttraumatic stress reactions, anxiety and depression following the premature birth of their baby, which subsequently may impact on the mother-baby-interactions, their attachment relationship and the cognitive, social and behavioural development of the baby. In this pilot study, we offered an expressive writing intervention to women who recently had a premature baby to alleviate their psychological distress and to improve their physical health. During the expressive writing intervention, women were asked to write down their deepest thoughts and feelings about the most traumatic aspect of their experience of having a premature baby for 15 min over three consecutive days. The aims of the study were as follows: (1) To evaluate the effect of expressive writing on psychological and physical health in women who recently had a premature baby. (2) To evaluate the effect of expressive writing on the use of healthcare services and medication in this population. (3) To evaluate the acceptability and feasibility of this intervention for this population. Forty participants were randomly allocated to either the expressive writing intervention group or a wait list control group. Pre- and post questionnaires to evaluate the effectiveness of the expressive writing intervention, as well as their acceptability and feasibility were completed. The intervention took place when the baby was 3 months of corrected age. Post-measures were completed at 1 and 3 months following the intervention. Results and their clinical implications will be discussed with regards to the implementation of this safe and cost-effective method as a preventative measure in the routine care of women who recently gave birth to a premature baby

Care related pain in rehabilitation after orthopedic trauma: An exploratory study with qualitative data.

OBJECTIVE: Care related pain (CRP) is generally under-estimated and rarely studied in rehabilitation as well as in general medecine. Beliefs about pain influence psychological distress, adjustment to pain and physical disability. In this sense, perceptions of CRP could limit recovery. This exploratory study aims to understand patients' and caregivers' subjective perceptions and beliefs about CRP. PATIENTS AND METHODS: Questionnaires about CRP were submitted to members of the interdisciplinary team of a rehabilitation hospital and to patients with musculoskeletal complaints (cross-sectional design). Twenty patients were also individually interviewed (qualitative data). Four topics were addressed: frequency of CRP, situations and procedures causing CRP, beliefs about CRP and means used to deal with CRP. RESULTS: Seventy-five caregivers and 50 patients replied to the questionnaire. CRP is a very common experience in rehabilitation and it is recognized by both groups. Generally, the situations causing CRP reflect the specificity of rehabilitation (mobilization...) and are similarly perceived by patients and caregivers, with patients considering them as more painful. Beliefs about CRP are clearly different from those usually associated with pain. Both groups point out the utilitarian and the inevitable character of CRP. They differ on that, that patients had a more positive view about CRP. They associate it more often with progress and see it as acceptable at least until a certain limit. They are also able to perceive the richness of means used by physiotherapists to help them coping with CRP. CONCLUSION: Our data may suggest new keys to motivate patient to be active in rehabilitation for example in choosing carefully arguments or words which may fit theirs' beliefs about CRP, or in using various means to manage CRP. Promoting the use of relational competences with chronic pain patients and of a patient-centred approach may also be a concern in training caregivers.
