Reproducibility and feasibility of a 22 joints ultrasound score in rheumatoid arthritis: a study among rheumatologists with diverse expertise in musculoskeletal ultrasound

Objective: To assess reproducibility and feasibility of amusculoskeletal ultrasound (US) score for rheumatoid arthritis amongrheumatologist with diverse expertise in US, working in private orhospital practice.Methods: The Swiss Sonography in Arthritis and Rheumatism(SONAR) group has developed a semi-quantitative score for RA usingOMERACT criteria for synovitis and erosion. The score was taught torheumatologists trained in US through two workshops. Subsequently,they were encouraged to practice in their office. For the study, we used6 US machines of different quality, each with a different patient.19 readers randomly selected among rheumatologists who haveattended both workshops, were asked to score anonymously at leastone patient. To assess whether some factors influence the score, weasked each reader to answer questionnaire describing his experiencewith US.Results: 19 rheumatologists have performed 29 scans, each patienthaving been evaluated by 4 to 6 readers. Median time for examcompletion was 20 minutes (range 15 to 60 mn). 53% ofrheumatologists work in private practice. Graph 1 show the global greyscale score for each patient. Weighted kappa was calculated for eachpair of reader using stata11. Almost all kappa of poor agreement wereobtained with a low quality device or by an assessor who havepreviously performed less than 5 scores himself.Conclusions: This is the first study to show an US score for RAfeasible by rheumatologists with diverse expertise in US both in privateand hospital practice. Reproducibility seemed to be influenced by thequality of device and previous experience with the score.

Beyond splitting: observer-rated defense mechanisms in borderline personality disorder

Defense mechanism is a key concept in the psychoanalytic psychopathology of borderline personality disorder (BPD). Theoretical and empirical elaborations on this question are briefly reviewed and discussed with respect to process assessment of defense mechanisms; we put forward observer-rater methodology as an accurate means of assessing unconscious in-session processes. A sample of 25 patients presenting with BPD were interviewed, as were subjects from a matched control group without psychiatric symptoms (n = 25), using a psychodynamic interview paradigm. These interviews were transcribed and rated using the Defense Mechanisms Rating Scales. The results indicate that, compared to controls, patients with BPD used higher percentages of a action, borderline, disavowal, narcissistic, and hysteric defenses, along with lower levels of mature and obsessional defenses. Overall defensive functioning was significantly lower in the patients with BPD, compared to controls. Narcissistic defenses were related with symptom level. These results are discussed in light of previous studies on defensive functioning of BPD and the literature on psychoanalytic psychopathology. These results have several important clinical implications.

Comparison of purified 12 kDa and recombinant 15 kDa Fasciola hepatica antigens related to a Schistosoma mansoni fatty acid binding protein

Vaccines in schistosomiasis using homologous antigens have been studied extensively in experimentally infected mammalian hosts. Vaccines using heterologous antigens have received comparatively less attention. This review summarizes recent work on a heterologous 12 kDa Fasciola hepatica antigenic polypeptide which cross reacts with Schistosoma mansoni. A cDNA has been cloned and sequenced, and the predicted amino acid sequence of the recombinant protein has been shown to have significant (44) identity with a 14 kDa S. mansoni fatty acid binding protein. Thus in the parasitic trematodes fatty acid binding proteins may be potential vaccine candidates. The F. hepatica recombinant protein has been overexpressed and purified and denoted rFh15. Preliminary rFh15 migrates more slowly (i.e. may be slightly larger) than nFh12 on SDS-PAGE and has a predicted pI of 6.01 vs. observed pI of 5.45. Mice infected with F. hepatica develop antibodies to nFh12 by 2 weeks of infection vs. 6 weeks of infection to rFh15; on the other hand, mice with schistosomiasis mansoni develop antibodies to both nFh12 and rFh15 by 6 weeks of infection. Both the F. hepatica and S. mansoni cross-reactive antigens may be cross-protective antigens with the protection inducing capability against both species.

Role of the hypocretin system in cocaine- and alcohol-related behaviors : evidence from hypocretin-deficient mice

RésuméL'addiction aux drogues est une maladie multifactorieile affectant toutes les strates de notre société. Cependant, la vulnérabilité à développer une addiction dépend de facteurs environnementaux, génétiques et psychosociaux. L'addiction aux drogues est décrite comme étant une maladie chronique avec un taux élevé de rechutes. Elle se caractérise par un besoin irrépressible de consommer une drogue et une augmentation progressive de la consommation en dépit des conséquences néfastes. Les mécanismes cérébraux responsables des dépendances aux drogues ne sont que partiellement élucidés, malgré une accumulation croissante d'évidences démontrant des adaptations au niveau moléculaire et cellulaire au sein des systèmes dopaminergique et glutamatergique. L'identification de nouveaux facteurs neurobiologiques responsables de la vulnérabilité aux substances d'abus est cruciale pour le développement de nouveaux traitements thérapeutiques capables d'atténuer et de soulager les symptômes liés à la dépendance aux drogues.Au cours des dernières années, de nombreuses études ont démontré qu'un nouveau circuit cérébral, le système hypocrétinergique, était impliqué dans plusieurs fonctions physiologiques, tel que l'éveil, le métabolisme énergétique, la motivation, le stress et les comportements liés aux phénomènes de récompense. Le système hypocrétinergique est composé d'environ 3000-4000 neurones issus de l'hypothalamus latéral projetant dans tout ie cerveau. Des souris transgéniques pour le gène des hypocrétines ont été générées et leur phénotype correspond à celui des animaux sauvages, excepté le fait qu'elles soient atteintes d'attaques de sommeil similaires à celles observées chez les patients narcoleptiques. H semblerait que les hypocrétines soient requises pour l'acquisition et l'expression de la dépendance aux drogues. Cependant, le mécanisme précis reste encore à être élucidé. Dans ce rapport, nous rendons compte des comportements liés aux phénomènes de récompense liés à l'alcool et à la cocaine chez les souris knock-out (KO), hétérozygotes (HET) et sauvages (WT).Nous avons, dans un premier temps, évalué l'impact d'injections répétées de cocaïne (15 mg/kg, ip) sur la sensibilisation locomotrice et sur le conditionnement place préférence. Nous avons pu observer que les souris WT, HET et KO exprimaient une sensibilisation locomotrice induite par une administration chronique de cocaïne, cependant les souris déficientes en hypocrétines démontraient une sensibilisation retardée et atténuée. Π est intéressant de mentionner que les mâles HET exprimaient une sensibilisation comportementale intermédiaire. Après normalisation des données, toutes les souris exprimaient une amplitude de sensibilisation similaire, excepté les souris mâles KO qui affichaient, le premier jour de traitement, une sensibilisation locomotrice réduite et retardée, reflétant un phénotype hypoactif plutôt qu'une altération de la réponse aux traitements chroniques de cocaïne. Contre toute attente, toutes les souris femelles exprimaient un pattern similaire de sensibilisation locomotrice à la cocaïne. Nous avons ensuite évalué l'effet d'un conditionnement comportemental à un environnement associé à des injections répétées de cocaine (15 mg / kg ip). Toutes les souris, quelque soit leur sexe ou leur génotype, ont manifesté une préférence marquée pour l'environnement apparié à la cocaïne. Après deux semaines d'abstinence à la cocaïne, les mâles et les femelles déficientes en hypocrétines n'exprimaient plus aucune préférence pour le compartiment précédemment associé à la cocaïne. Alors que les souris WT et HET maintenaient leur préférence pour le compartiment associé à la cocaïne. Pour finir, à l'aide d'un nouveau paradigme appelé IntelliCage®, nous avons pu évaluer la consommation de liquide chez les femelles WT, HET et KO. Lorsqu'il n'y avait que de l'eau disponible, nous avons observé que les femelles KO avaient tendance à moins explorer les quatre coins de la cage. Lorsque les souris étaient exposées à quatre types de solutions différentes (eau, ImM quinine ou 0.2% saccharine, alcool 8% et alcool 16%), les souris KO avaient tendance à moins consommer l'eau sucrée et les solutions alcoolisées. Cependant, après normalisation des données, aucune différence significative n'a pu être observée entre les différents génotypes, suggérant que la consommation réduite d'eau sucrée ou d'alcool peut être incombée à l'hypoactivité des souris KO.Ces résultats confirment que le comportement observé chez les souris KO serait dû à des compensations développementales, puisque la sensibilisation locomotrice et le conditionnement comportemental à la cocaïne étaient similaires aux souris HET et WT. En ce qui concerne la consommation de liquide, les souris KO avaient tendance à consommer moins d'eau sucrée et de solutions alcoolisées. Le phénotype hypoactif des souris déficientes en hypocrétine est probablement responsable de leur tendance à moins explorer leur environnement. Il reste encore à déterminer si l'expression de ce phénotype est la conséquence d'un état de vigilance amoindri ou d'une motivation diminuée à la recherche de récompense. Nos résultats suggèrent que les souris déficientes en hypocrétine affichent une motivation certaine à la recherche de récompense lorsqu'elles sont exposées à des environnements où peu d'efforts sont à fournir afin d'obtenir une récompense.AbstractDrug addiction is a multifactorial disorder affecting human beings regardless their education level, their economic status, their origin or even their gender, but the vulnerability to develop addiction depends on environmental, genetic and psychosocial dispositions. Drug addiction is defined as a chronic relapsing disorder characterized by compulsive drug seeking, with loss of control over drug intake and persistent maladaptive decision making in spite of adverse consequences. The brain mechanisms responsible for drug abuse remain partially unknown despite accumulating evidence delineating molecular and cellular adaptations within the glutamatergic and the dopaminergic systems. However, these adaptations do not fully explain the complex brain disease of drug addiction. The identification of other neurobiological factors responsible for the vulnerability to substance abuse is crucial for the development of promising therapeutic treatments able to alleviate signs of drug dependence.For the past few years, growing evidence demonstrated that a recently discovered brain circuit, the hypocretinergic system, is implicated in many physiological functions, including arousal, energy metabolism, motivation, stress and reward-related behaviors. The hypocretin system is composed of a few thousands neurons arising from the lateral hypothalamus and projecting to the entire brain. Hypocretin- deficient mice have been generated, and unexpectedly, their phenotype resembles that of wild type mice excepting sleep attacks strikingly similar to those of human narcolepsy patients. Evidence suggesting that hypocretins are required for the acquisition and the expression of drug addiction has also been reported; however the precise mechanism by which hypocretins modulate drug seeking behaviors remains a matter of debate. Here, we report alcohol and cocaine reward-related behaviors in hypocretin-deficient mice (KO), as well as heterozygous (HET) and wild type (WT) littermates.We first evaluated the impact of repeated cocaine injections (15 mg/kg, ip) on locomotor sensitization and conditioned place preference. We observed that WT, HET and KO mice exhibited behavioral sensitization following repeated cocaine administrations, but hypocretin deficient males displayed a delayed and attenuated response to chronic cocaine administrations. Interestingly, HET males exhibited an intermediate pattern of behavioral sensitization. However, after standardization of the post-injection data versus the period of habituation prior to cocaine injections, all mice displayed similar amplitudes of behavioral sensitization, except a reduced response in KO males on the first day, suggesting that the delayed and reduced cocaine-induced locomotor sensitization may reflect a hypoactive phenotype and probably not an altered response to repeated cocaine administrations. Unexpectedly, all female mice exhibited similar patterns of cocaine-induced behavioral sensitization. We then assessed the behavioral conditioning for an environment repeatedly paired with cocaine injections (15 mg/kg ip). All mice, whatever their gender or genotype, exhibited a robust preference for the environment previously paired with cocaine administrations. Noteworthy, following two weeks of cocaine abstinence, hypocretin-deficient males and females no longer exhibited any preference for the compartment previously paired with cocaine rewards whereas both WT and HET mice continued manifesting a robust preference. We finally assessed drinking behaviors in WT, HET and KO female mice using a novel paradigm, the IntelliCages®. We report here that KO females tended to less explore the four cage comers where water was easily available. When exposed to four different kinds of liquid solutions (water, ImM quinine or saccharine 0.2%, alcohol 8% and alcohol 16%), KO mice tended to less consume the sweet and the alcoholic beverages. However, after data standardization, no significant differences were noticed between genotypes suggesting that the hypoactive phenotype is most likely accountable for the trend regarding the reduced sweet or alcohol intake in KO.Taken together, the present findings confirm that the behavior seen in Hcrt KO mice likely reflects developmental compensations since only a slightly altered cocaine-induced behavioral sensitization and a normal behavioral conditioning with cocaine were observed in these mice compared to HET and WT littermates. With regards to drinking behaviors, KO mice barely displayed any behavioral changes but a trend for reducing sweet and alcoholic beverages. Overall, the most striking observation is the constant hypoactive phenotype seen in the hypocretin-deficient mice that most likely is accountable for their reduced tendency to explore the environment. Whether this hypoactive phenotype is due to a reduced alertness or reduced motivation for reward seeking remains debatable, but our findings suggest that the hypocretin-deficient mice barely display any altered motivation for reward seeking in environments where low efforts are required to access to a reward.

Former eating disorder impairs 3rd person but not 1st person perspective taking. Does dance training help?

The mental ability to take the perspective of another person may depend on one's own bodily awareness and experience. In the present study, the former was defined as having a history of an eating disorder, and the latter variable was defined as formal experience with dance. The study used a 2 × 2 × 2 factorial design in which reaction times in two mental perspective taking tasks were compared between female dancers and non-dancers with and without a former eating disorder. Participants were asked to imagine two perspectives: i) the position of front-facing and back-facing figures (3rd person perspective taking task) and ii) that these same figures are a self reflection in a mirror (1st person perspective taking task). In both tasks, a particular hand was indicated in the presented figures, and the participants had to decide whether the hand represented their own left or right hand. Overall, responses were slower for front-facing than back-facing figures in the 3rd person perspective taking task, and for back-facing than front-facing figures in the 1st person perspective taking task. Importantly, having a former history of an eating disorder related to a decreased performance in the 3rd person perspective taking task, but only in participants without dance experience. Results from an additional control group (a history of exercise but no dance experience) indicated that dance is particularly beneficial for mental bodily perspective taking. Dance experience, more so than exercise in general, can benefit 3rd person or extrapersonal perspective taking, supporting the favourable impact this exercise has on own body processing

Musculoskeletal Conditions Briefing

Musculoskeletal conditions (MSCs) are a group of diseases that affect the body’s bones, joints, muscles and the tissues that connect them. Common MSCs include back pain, rheumatoid arthritis, osteoarthritis, osteoporosis, and spinal disorders. MSCs are the most common cause of severe long term pain and physical disability in developed countries. They significantly affect the psychosocial wellbeing of individuals as well as their families and carers. They are responsible for substantial costs to the health and social care system and the economy. They are a leading cause of absence from work and lost productivity at work. MSCs comprise a diverse group of conditions. Some have a specific medical diagnosis (eg rheumatoid arthritis) but others have no clear medical diagnosis (eg back pain). Risk factors for the development and progression of MSCs include age, sex, family history, obesity, physical inactivity, injury and biomechanical occupational health issues.

Female asylum seekers with musculoskeletal pain: the importance of diagnosis and treatment of hypovitaminosis D.

BACKGROUND: Hypovitaminosis D is well known in different populations, but may be under diagnosed in certain populations. We aim to determine the first diagnosis considered, the duration and resolution of symptoms, and the predictors of response to treatment in female asylum seekers suffering from hypovitaminosis D. METHODS: Design: A pre- and post-intervention observational study. Setting: A network comprising an academic primary care centre and nurse practitioners. Participants: Consecutive records of 33 female asylum seekers with complaints compatible with osteomalacia and with hypovitaminosis D (serum 25-(OH) vitamin D < 21 nmol/l). Treatment intervention: The patients received either two doses of 300,000 IU intramuscular cholecalciferol as well as 800 IU of cholecalciferol with 1000 mg of calcium orally, or the oral treatment only. Main outcome measures: We recorded the first diagnosis made by the physicians before the correct diagnosis of hypovitaminosis D, the duration of symptoms before diagnosis, the responders and non-responders to treatment, the duration of symptoms after treatment, and the number of medical visits and analgesic drugs prescribed 6 months before and 6 months after diagnosis. Tests: Two-sample t-tests, chi-squared tests, and logistic regression analyses were performed. Analyses were performed using SPSS 10.0. RESULTS: Prior to the discovery of hypovitaminosis D, diagnoses related to somatisation were evoked in 30 patients (90.9%). The mean duration of symptoms before diagnosis was 2.53 years (SD 3.20). Twenty-two patients (66.7%) responded completely to treatment; the remaining patients were considered to be non-responders. After treatment was initiated, the responders' symptoms disappeared completely after 2.84 months. The mean number of emergency medical visits fell from 0.88 (SD 1.08) six months before diagnosis to 0.39 (SD 0.83) after (P = 0.027). The mean number of analgesic drugs that were prescribed also decreased from 1.67 (SD 1.5) to 0.85 (SD 1) (P = 0.001). CONCLUSION: Hypovitaminosis D in female asylum seekers may remain undiagnosed, with a prolonged duration of chronic symptoms. The potential pitfall is a diagnosis of somatisation. Treatment leads to a rapid resolution of symptoms, a reduction in the use of medical services, and the prescription of analgesic drugs in this vulnerable population.

Sex-related and non-sex-related comorbidity subtypes of tic disorders: a latent class approach.

BACKGROUND AND PURPOSE: Recent evidence suggests that there may be more than one Gilles de la Tourette syndrome (GTS)/tic disorder phenotype. However, little is known about the common patterns of these GTS/tic disorder-related comorbidities. In addition, sex-specific phenomenological data of GTS/tic disorder-affected adults are rare. Therefore, this community-based study used latent class analyses (LCA) to investigate sex-related and non-sex-related subtypes of GTS/tic disorders and their most common comorbidities. METHODS: The data were drawn from the PsyCoLaus study (n = 3691), a population-based survey conducted in Lausanne, Switzerland. LCA were performed on the data of 80 subjects manifesting motor/vocal tics during their childhood/adolescence. Comorbid attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder, depressive, phobia and panic symptoms/syndromes comprised the selected indicators. The resultant classes were characterized by psychosocial correlates. RESULTS: In LCA, four latent classes provided the best fit to the data. We identified two male-related classes. The first class exhibited both ADHD and depression. The second class comprised males with only depression. Class three was a female-related class depicting obsessive thoughts/compulsive acts, phobias and panic attacks. This class manifested high psychosocial impairment. Class four had a balanced sex proportion and comorbid symptoms/syndromes such as phobias and panic attacks. The complementary occurrence of comorbid obsessive thoughts/compulsive acts and ADHD impulsivity was remarkable. CONCLUSIONS: To the best of our knowledge, this is the first study applying LCA to community data of GTS symptoms/tic disorder-affected persons. Our findings support the utility of differentiating GTS/tic disorder subphenotypes on the basis of comorbid syndromes.

Influence of the in vivo deregulation of the expression of ntrk3 (trkc) on cortical development of a murine model of panic/anxiety disorder

Alteracions durant el desenvolupament cerebral produirien canvis en la connectivitat neuronal i la bioquímica cel•lular que podrien resultar en una disfunció cognitiva i/o emocional, desembocant a trastorns psiquiàtrics. Les neurotrofines intervenen en els processos del neurodesenvolupament i en la funcionalitat del cervell adult i, conseqüentment, serien bons candidats com a factors de predisposició en diverses malalties mentals. S’ha suggerit la implicació del receptor de la neurotrofina 3, TrkC, en el trastorn de pànic. Nosaltres proposem que la sobreexpressió del gen NTRK3 (TrkC) és un mediador comú dels desencadenants genètics i ambientals d’aquest trastorn. Concretament, la seva desregulació podria produir canvis estructurals i funcionals a l’escorça cerebral dels pacients pel seu paper durant l’establiment dels circuïts corticals i la neuroplasticitat a l’adult, probablement esdevenint elements de predisposició a patir atacs de pànic. Els objectius principals d’aquest treball han estat: 1/determinar la contribució específica del gen NTRK3 a les alteracions de l’escorça cerebral observades en pacients, utilitzant un model murí modificat genèticament (TgNTRK3), i 2/analitzar l’impacte específic de la sobreexpressió de NTRK3 sobre la corticogènesi durant estadis embrionaris o postnatals estudiant la neurogènesi i la neuritogènesi. Els resultats indiquen que la sobreexpressió de NTRK3 als ratolins produeix una reducció del gruix de l’escorça frontal, recapitulant la hipofrontalitat dels pacients, que comportaria una menor inhibició dels nuclis subcorticals del sistema límbic com l’amígdala, i alteracions citoarquitectòniques a l’escorça prefrontal medial que recolzen la hipòtesi del seu mal funcionament. Tanmateix, els ratolins TgNTRK3 presenten canvis estructurals a l’escorça somatosensorial, suggerint que el processament de la informació sensorial podria estar alterat, el que encara no s’ha explorat en pacients. La sobreexpressió de NTRK3 també afecta la neuritogènesi en cultius primaris corticals i modifica la resposta de les neurones a l’estimulació amb neurotrofines. Per tant, el fenotip cortical adult dels TgNTRK3 podria dependre d’alteracions durant la corticogènesi.

Glucose transporter-1 deficiency syndrome: the expanding clinical and genetic spectrum of a treatable disorder.

Glucose transporter-1 deficiency syndrome is caused by mutations in the SLC2A1 gene in the majority of patients and results in impaired glucose transport into the brain. From 2004-2008, 132 requests for mutational analysis of the SLC2A1 gene were studied by automated Sanger sequencing and multiplex ligation-dependent probe amplification. Mutations in the SLC2A1 gene were detected in 54 patients (41%) and subsequently in three clinically affected family members. In these 57 patients we identified 49 different mutations, including six multiple exon deletions, six known mutations and 37 novel mutations (13 missense, five nonsense, 13 frame shift, four splice site and two translation initiation mutations). Clinical data were retrospectively collected from referring physicians by means of a questionnaire. Three different phenotypes were recognized: (i) the classical phenotype (84%), subdivided into early-onset (<2 years) (65%) and late-onset (18%); (ii) a non-classical phenotype, with mental retardation and movement disorder, without epilepsy (15%); and (iii) one adult case of glucose transporter-1 deficiency syndrome with minimal symptoms. Recognizing glucose transporter-1 deficiency syndrome is important, since a ketogenic diet was effective in most of the patients with epilepsy (86%) and also reduced movement disorders in 48% of the patients with a classical phenotype and 71% of the patients with a non-classical phenotype. The average delay in diagnosing classical glucose transporter-1 deficiency syndrome was 6.6 years (range 1 month-16 years). Cerebrospinal fluid glucose was below 2.5 mmol/l (range 0.9-2.4 mmol/l) in all patients and cerebrospinal fluid : blood glucose ratio was below 0.50 in all but one patient (range 0.19-0.52). Cerebrospinal fluid lactate was low to normal in all patients. Our relatively large series of 57 patients with glucose transporter-1 deficiency syndrome allowed us to identify correlations between genotype, phenotype and biochemical data. Type of mutation was related to the severity of mental retardation and the presence of complex movement disorders. Cerebrospinal fluid : blood glucose ratio was related to type of mutation and phenotype. In conclusion, a substantial number of the patients with glucose transporter-1 deficiency syndrome do not have epilepsy. Our study demonstrates that a lumbar puncture provides the diagnostic clue to glucose transporter-1 deficiency syndrome and can thereby dramatically reduce diagnostic delay to allow early start of the ketogenic diet.

Variant within the promoter region of the CHRNA3 gene associated with FTN dependence is not related to self-reported willingness to quit smoking.

INTRODUCTION: Common variation in the CHRNA5-CHRNA3-CHRNB4 gene region is robustly associated with smoking quantity. Conversely, the association between one of the most significant single nucleotide polymorphisms (SNPs; rs1051730 within the CHRNA3 gene) with perceived difficulty or willingness to quit smoking among current smokers is unknown. METHODS: Cross-sectional study including current smokers, 502 women, and 552 men. Heaviness of smoking index (HSI), difficulty, attempting, and intention to quit smoking were assessed by questionnaire. RESULTS: The rs1051730 SNP was associated with increased HSI (age, gender, and education-adjusted mean ± SE: 2.6 ± 0.1, 2.2 ± 0.1, and 2.0 ± 0.1 for AA, AG, and GG genotypes, respectively, p < .01). Multivariate logistic regression adjusting for gender, age, education, leisure-time physical activity, and personal history of cardiovascular or lung disease showed rs1051730 to be associated with higher smoking dependence (odds ratio [OR] and 95% CI for each additional A-allele: 1.38 [1.11-1.72] for smoking more than 20 cigarette equivalents/day; 1.31 [1.00-1.71] for an HSI ≥5 and 1.32 [1.05-1.65] for smoking 5 min after waking up) and borderline associated with difficulty to quit (OR = 1.29 [0.98-1.70]), but this relationship was no longer significant after adjusting for nicotine dependence. Also, no relationship was found with willingness (OR = 1.03 [0.85-1.26]), attempt (OR = 1.00 [0.83-1.20]), or preparation (OR = 0.95 [0.38-2.38]) to quit. Similar findings were obtained for other SNPs, but their effect on nicotine dependence was no longer significant after adjusting for rs1051730. Conclusions: These data confirm the effect of rs1051730 on nicotine dependence but failed to find any relationship with difficulty, willingness, and motivation to quit.

Fuel Poverty and Cold Home-related Health Problems

Evidence Review 7 - Tackling fuel poverty and cold home-related health problems Briefing 7 - Fuel poverty and cold home-related health problems This pair of documents, commissioned by Public Health England, and written by the UCL Institute of Health Equity, address the health impacts of fuel poverty and cold homes. These documents provide an overview of fuel poverty, describing the evidence linking fuel poverty, cold homes, and poor health outcomes. They examine the scale of the problem across England and trends over time. Evidence shows that living in cold homes is associated with poor health outcomes and an increased risk of morbidity and mortality for all age groups. The documents also provide a brief overview of national policy and sets out the role of local authorities and potential interventions at local level. Fuel poverty is not just about poverty, but also about the quality of England’s housing stock and energy efficiency. The review discusses some of the interventions that have been implemented at the local level to help people on low incomes during cold weather and to address cold home-related health problems. The full evidence review and a shorter summary briefing are available to download above. This document is part of a series. An overview document which provides an introduction to this and other documents in the series, and links to the other topic areas, is available on the ‘Local Action on health inequalities’ project page. A video of Michael Marmot introducing the work is also available on our videos page.

Cognitive behavioural therapy leaflet.

This leaflet is for anyone who wants to know more about Cognitive Behavioural Therapy (CBT).It discusses how it works, why it is used, its effects, its side-effects, and alternative treatments. If you can't find what you want here, there are sources of further information at the end of this leaflet. What is CBT? It is a way of talking about: ï,§ how you think about yourself, the world and other people ï,§ how what you do affects your thoughts and feelings. CBT can help you to change how you think ('Cognitive') and what you do ('Behaviour'). These changes can help you to feel better. Unlike some of the other talking treatments, it focuses on the 'here and now' problems and difficulties. Instead of focusing on the causes of your distress or symptoms in the past, it looks for ways to improve your state of mind now. When does CBT help? CBT has been shown to help with many different types of problems. These include: anxiety, depression, panic, phobias (including agoraphobia and social phobia), stress, bulimia, obsessive compulsive disorder, post-traumatic stress disorder, bipolar disorder and psychosis. CBT may also help if you have difficulties with anger, a low opinion of yourself or physical health problems, like pain or fatigue. How does it work? CBT can help you to make sense of overwhelming problems by breaking them down into smaller parts. This makes it easier to see how they are connected and how they affect you. These parts are: ï,§ A Situation - a problem, event or difficult situation. From this can follow: ï,§ Thoughts ï,§ Emotions ï,§ Physical feelings ï,§ Actions Each of these areas can affect the others. How you think about a problem can affect how you feel physically and emotionally. All these areas of life can connect like this: {5 Areas - click related link below} What happens in one of these areas can affect all the others. There are helpful and unhelpful ways of reacting to most situations, depending on how you think about it. The way you think can be helpful - or unhelpful. An example: If you go home feeling depressed, you'll probably brood on what has happened and feel worse. If you get in touch with the other person, there's a good chance you'll feel better about yourself. If you avoid the other person, you won't be able to correct any misunderstandings about what they think of you - and you will probably feel worse. This 'vicious circle' can make you feel worse. It can even create new situations that make you feel worse. You can start to believe quite unrealistic (and unpleasant) things about yourself. This happens because, when we are distressed, we are more likely to jump to conclusions and to interpret things in extreme and unhelpful ways. CBT can help you to break this vicious circle of altered thinking, feelings and behaviour. When you see the parts of the sequence clearly, you can change them - and so change the way you feel. CBT aims to get you to a point where you can 'do it yourself', and work out your own ways of tackling these problems.
