Do Psychosocial Interventions Improve Quality of Life and Wellbeing in Adults with Neuromuscular Disorders? A Systematic Review and Narrative Synthesis

Background: Quality of life and well-being are frequently restricted in adults with neuromuscular disorders. As such, identification of appropriate interventions is imperative. Objective: The objective of this paper was to systematically review and critically appraise quantitative studies (RCTs, controlled trials and cohort studies) of psychosocial interventions designed to improve quality of life and well-being in adults with neuromuscular disorders. Method: A systematic review of the published and unpublished literature was conducted. Studies meeting inclusion criteria were appraised using a validated quality assessment tool and results presented in a narrative synthesis. Results: Out of 3,136 studies identified, ten studies met criteria for inclusion within the review. Included studies comprised a range of interventions including: cognitive behavioural therapy, dignity therapy, hypnosis, expressive disclosure, gratitude lists, group psychoeducation and psychologically informed rehabilitation. Five of the interventions were for patients with Amyotrophic Lateral Sclerosis (ALS). The remainder were for patients with post-polio syndrome, muscular dystrophies and mixed disorders, such as Charcot-Marie-Tooth disease, myasthenia gravis and myotonic dystrophy. Across varied interventions and neuromuscular disorders, seven studies reported a short-term beneficial effect of intervention on quality of life and well-being. Whilst such findings are encouraging, widespread issues with the methodological quality of these studies significantly compromised the results. Conclusion: There is no strong evidence that psychosocial interventions improve quality of life and well-being in adults with neuromuscular disorders, due to a paucity of high quality research in this field. Multi-site, randomised controlled trials with active controls, standardised outcome measurement and longer term follow-ups are urgently required.

Investigating the Function of a Small Secreted Protein Family in Physcomitrella Patens

The correct development of multicellular organisms depends upon the perception of signals secreted by cells in order to co-ordinate cell differentiation. The Physcomitrella patens genome encodes many components of potential signaling systems, including putative receptor proteins and putative secreted protein ligands, yet at present little characterization of these proteins has been carried out. We are currently attempting to characterize the expression pattern and function of a family of 6 secreted proteins exhibiting homology to PrsS, the ligand that controls self-incompatibility (SI) in Papaver rhoeas (field poppy). In poppy, PrsS interacts a receptor on the surface of pollen tubes, PrpS causing SI by programmed cell death. Homologues of this protein (SPH – S-Protein Homologues) exist in dicotyledonous plants and bryophytes but not in other plant taxa. We aim to determine spatiotemporal expression differences between these proteins via reporter gene analysis and qPCR of cDNA. In addition we are in the process of creating targeted gene knockouts for all 6 of the genes in P. patens. We are also searching for receptors of PrpS in Physcomitrella using a bioinformatic strategy alongside phage display. In accomplishing this we hope to determine the function of a small novel secreted protein family in Physcomitrella but in addition we also hope to elucidate the function of SPH proteins in Arabidopsis.

Relation entre la représentation de la maladie et le bien-être subjectif et psychologique chez des patients atteints de cancer

L’annonce d’un diagnostic de cancer a un impact important sur l’individu. En se basant sur des informations sociales, environnementales et personnelles, celui-ci tentera de se représenter la maladie. Cette représentation constitue une grille d’informations cognitives et émotionnelles servant à donner un sens à la maladie et y réagir. Le modèle d’autorégulation de Leventhal propose qu’en fonction de sa représentation de la maladie, un individu mettra de l’avant différentes stratégies d’adaptation; ultimement, ces stratégies auront un impact sur l’issue de la maladie dont le niveau de bien-être. La présente recherche propose de considérer l’avenue tant hédonique qu’eudémonique du bien-être, en y incluant le bien-être subjectif, correspondant aux affects positifs et négatifs et à la satisfaction de vie et le bien-être psychologique correspondant à un état d’épanouissement personnel. L’étude a pour objectif principal de documenter les liens entre les dimensions cognitives et émotionnelles de la représentation de la maladie et les dimensions du bien-être subjectif (avenue hédonique) et le bien-être psychologique (avenue eudémonique). Plus précisément, les hypothèses postulent qu’une représentation plus positive de la maladie a pour effet d’augmenter le bien-être subjectif et psychologique. Les hypothèses postulent que la dimension de la représentation émotionnelle de la maladie joue un rôle médiateur entre les dimensions cognitives de la représentation de la maladie et le bien-être subjectif et psychologique. Pour atteindre ces objectifs, 70 participants âgés entre 31 et 75 ans ayant été atteints de cancer dans les cinq dernières années ont été recrutés. Les données ont été recueillies à l’aide de questionnaires autorapportés : un questionnaire sociodémographique, les versions francophones du Revised Illness Perception Questionnaire (IPQ-R : Moss-Morris et al., 2002), du Positive and Negative Affect Scale (PANAS ; Watson, Clark, & Tellegen, 1988), du Satisfaction with Life Scale (Diener, Emmons, Larsen, & Griffin, 1985) et du The Scales of Psychological Well-Being (Ryff & Essex, 1992). Des analyses statistiques de régressions multiples et de médiation ont été réalisées à l’aide du logiciel Statistical Package for Social Sciences (SPSS). Les résultats indiquent que seulement certaines dimensions de la représentation de la maladie exercent un effet unique sur le bien-être subjectif et/ou psychologique soit le contrôle personnel perçu, la représentation émotionnelle de la maladie, les conséquences perçues de la maladie et le cours aigu/chronique de la maladie. La représentation émotionnelle de la maladie semble exercer un effet médiateur complet entre certaines dimensions cognitives de la représentation de la maladie et les niveaux de bien-être. C’est le cas pour l’identité, le cours aigu/chronique de la maladie, le cours cyclique de la maladie, les conséquences perçues de la maladie et l’efficacité perçue du traitement, lorsque mis en lien avec les affects négatifs. C’est aussi le cas pour l’identité et le cours cyclique de la maladie, lorsque mis en lien avec la satisfaction de vie, et pour le cours cyclique de la maladie et les conséquences perçues de la maladie, lorsque mis en lien avec le bien-être psychologique. Les affects positifs associés au volet affectif du bien-être subjectif ne sont pas affectés par la représentation de la maladie.

Adiponectin and insulin in grey seals during suckling and fasting: relationship with nutritional state and body mass during nursing in mothers and pups

Animals that fast during breeding and/or development, such as phocids, must regulate energy balance carefully to maximize reproductive fitness and survival probability. Adiponectin, produced by adipose tissue, contributes to metabolic regulation by modulating sensitivity to insulin, increasing fatty acid oxidation by liver and muscle, and promoting adipogenesis and lipid storage in fat tissue. We tested the hypotheses that (1) circulating adiponectin, insulin, or relative adiponectin gene expression is related to nutritional state, body mass, and mass gain in wild gray seal pups; (2) plasma adiponectin or insulin is related to maternal lactation duration, body mass, percentage milk fat, or free fatty acid (FFA) concentration; and (3) plasma adiponectin and insulin are correlated with circulating FFA in females and pups. In pups, plasma adiponectin decreased during suckling (linear mixed-effects model [LME]: T = 4.49; P < 0.001) and the early postweaning fast (LME: T = 3.39; P = 0.004). In contrast, their blubber adiponectin gene expression was higher during the early postweaning fast than early in suckling (LME: T = 2.11; P = 0.046). Insulin levels were significantly higher in early (LME: T = 3.52; P = 0.004) and late (LME: T = 6.99; P < 0.001) suckling than in fasting and, given the effect of nutritional state, were also positively related to body mass (LME: T = 3.58; P = 0.004). Adiponectin and insulin levels did not change during lactation and were unrelated to milk FFA or percentage milk fat in adult females. Our data suggest that adiponectin, in conjunction with insulin, may facilitate fat storage in seals and is likely to be particularly important in the development of blubber reserves in pups.

The role of glucocorticoids in naturally fasting grey seal (Halichoerus grypus) pups: dexamethasone stimulates mass loss and protein utilisation, but not departure from the colony

Seals must manage their energy reserves carefully while they fast on land to ensure that they go to sea with sufficient fuel to sustain them until they find food. Glucocorticoids (GCs) have been implicated in the control of fuel metabolism and termination of fasting in pinnipeds. Here we tested the hypothesis that dexamethasone, an artificial GC, increases fat and protein catabolism, and induces departure from the breeding colony in wild, fasting grey seal pups. A single intramuscular dose of dexamethasone completely suppressed cortisol production for 24–72 h, demonstrating activation of GC receptors. In experiment 1, we compared the effects of a single dose of dexamethasone or saline administered 10 days after weaning on fasting mass and body composition changes, cortisol, blood urea nitrogen (BUN) and glucose levels, and timing of departure from the colony. In experiment 2, we investigated the effects of dexamethasone on short-term (5 days) changes in mass loss, body composition and BUN levels. In experiment 1, dexamethasone induced a short-lived increase in mass loss, but there was no difference in timing of departure between dexamethasone- and saline-treated pups (N=10). In experiment 2, dexamethasone increased protein and water loss and prevented a decrease in BUN levels (N=11). Our data suggest changes in cortisol contribute to regulation of protein catabolism in fasting seal pups, irrespective of the sex of the animal, but do not terminate fasting. By affecting the rate of protein depletion, lasting changes in cortisol levels could influence the amount of time seal pups have to find food, and thus may have important consequences for their survival.

Effects of handling regime and sex on changes in cortisol, thyroid hormones and body mass in fasting grey seal pups

Survival of seal pups may be affected by their ability to respond appropriately to stress. Chronic stress can adversely affect secretion of cortisol and thyroid hormones, which contribute to the control of fuel utilisation. Repeated handling could disrupt the endocrine response to stress and/or negatively impact upon mass changes during fasting. Here we investigated the effects of handling regime on cortisol and thyroid hormone levels, and body mass changes, in fasting male and female grey seal pups (Halichoerus grypus). Females had higher thyroid hormone levels than males throughout fasting and showed a reduction in cortisol midway through the fast that was not seen in males. This may reflect sex-specific fuel allocation or development. Neither handling frequency nor cumulative contact time affected plasma cortisol or thyroid hormone levels, the rate of increase in cortisol over the first five minutes of physical contact or the pattern of mass loss during fasting in either sex. The endocrine response to stress and the control of energy balance in grey seal pups appear to be robust to repeated, short periods of handling. Our results suggest that routine handling should have no additional impact on these animals than general disturbance caused by researchers moving around the colony.

Effects of age and body mass on development of diving capabilities of gray seal pups: costs and benefits of the postweaning fast

Development of adequate diving capabilities is crucial for survival of seal pups and may depend on age and body size. We tracked the diving behavior of 20 gray seal pups during their first 3 mo at sea using satellite relay data loggers. We employed quantile analysis to track upper limits of dive duration and percentage time spent diving, and lower limits of surface intervals. When pups first left the breeding colony, extreme (ninety-fifth percentile) dive duration and percentage time spent diving were positively correlated with age, but not mass, at departure. Extreme dive durations and percentage time spent diving peaked at [Formula: see text] d of age at values comparable with those of adults, but were not sustained. Greater peaks in extreme percentage time spent diving occurred in pups that had higher initial values, were older at their peak, and were heavier at departure. Pups that were smaller and less capable divers when they left the colony improved extreme dive durations and percentage time spent diving more rapidly, once they were at sea. Minimum survival time correlated positively with departure mass. Pups that were heavier at weaning thus benefitted from being both larger and older at departure, but smaller pups faced a trade-off. While age at departure had a positive effect on early dive performance, departure mass impacted on peak percentage time spent diving and longer-term survival. We speculate that once small pups have attained a minimum degree of physiological development to support diving, they would benefit by leaving the colony when younger but larger to maximize limited fuel reserves, rather than undergoing further maturation on land away from potential food resources, because poor divers may be able to "catch up" once at sea.

Factors influencing the radiative surface temperature of grey seal (Halichoerus grypus) pups during early and late lactation

The aim of this study was to examine the variation in body surface temperature of grey seal (Halichoerus grypus) pups throughout lactation in response to different environmental conditions. Radiative surface temperatures (T r, °C) of pups were measured on the Isle of May (56°11′N, 02°33′W), southeast Scotland from 29 October to 25 November 2003. Records were obtained from a total of 60 pups (32 female and 28 male) from three different pupping sites during early and late lactation. Pups were sheltered from high wind speeds but air temperature, humidity and solar radiation at pupping sites were similar to general meteorological conditions. The mean T r of all pups was 15.8°C (range 7.7–29.7°C) at an average air temperature of 10.2°C (range 6.5–13.8°C). There was no difference in the mean T r of pups between early and late lactation. However, the T r varied between different regions of the body with hind flippers on average 2–6°C warmer than all other areas measured. There was no difference in mean T r of male and female pups and pup body mass did not account for the variation in T r during early or late lactation. Throughout the day there was an increase in the T r of pups and this explained 20–28% of the variation in T r depending on stage of lactation. There was no difference in the mean T r of pups between pupping sites or associated with different substrate types. Wind speed and substrate temperature had no effect on the T r of pups. However, solar radiation, air temperature and relative humidity accounted for 48% of the variation in mean T r of pups during early lactation. During late lactation air temperature and solar radiation alone accounted for 43% of the variation in T r. These results indicate that environmental conditions explain only some of the variation in T r of grey seal pups in natural conditions. Differences in T r however indicate that the cost of thermoregulation for pups will vary throughout lactation. Further studies examining intrinsic factors such as blubber thickness and activity levels are necessary before developing reliable biophysical models for grey seals.

Hash-Tree Anti-Tampering Schemes

Procedures that provide detection, location and correction of tampering in documents are known as anti-tampering schemes. In this paper we describe how to construct an anti-tampering scheme using a pre-computed tree of hashes. The main problems of constructing such a scheme are its computational feasibility and its candidate reduction process. We show how to solve both problems by the use of secondary hashing over a tree structure. Finally, we give brief comments on our ongoing work in this area.

Women, workplace militancy and political subjectivity in Britain, 1968-1985

This thesis examines the experiences and political subjectivity of women who engaged in workplace protest in Britain between 1968 and 1985. The study covers a period that has been identified with the ‘zenith’ of trade-union militancy in British labour history. The women’s liberation movement also emerged in this period, which produced a shift in public debates about gender roles and relations in the home and the workplace. Women’s trade union membership increased dramatically and trade unions increasingly committed themselves to supporting ‘women’s issues’. Industrial disputes involving working-class women have frequently been cited as evidence of women’s growing participation in the labour movement. However, the voices and experiences of female workers who engaged in workplace protest remain largely unexplored. This thesis addresses this space through an original analysis of the 1968 sewing-machinists’ strike at Ford, Dagenham; the 1976 equal pay strike at Trico, Brentford; the 1972 Sexton shoe factory occupation in Fakenham, Norfolk; the 1981 Lee Jeans factory occupation in Greenock, Inverclyde and the 1984-1985 sewing-machinists’ strike at Ford Dagenham. Drawing upon a combination of oral history and written sources, this study contributes a fresh understanding of the relationship between feminism, workplace activism and trade unionism during the years 1968-1985. In every dispute considered in this thesis, women’s behaviour was perceived by observers as novel, ‘historic’ or extraordinary. But the women did not think of themselves as extraordinary, and rather understood their behaviour as a legitimate and justified response to their everyday experiences of gender and class antagonism. The industrial disputes analysed in this thesis show that women’s workplace militancy was not simply a direct response to women’s heightened presence in trade unions. The women involved in these disputes were more likely to understand their experiences of workplace activism as an expression of the economic, social and subjective value of their work. Whilst they did not adopt a feminist identity or associate their action with the WLM, they spoke about themselves and their motivations in a manner that emphasised feminist values of equality, autonomy and self-worth.
