Background. Demonstrating differences between euthymic bipolar subjects and healthy controls in response to positive (happy) mood induction may help elucidate how mania evolves. This pilot study evaluates the Go task in a reward paradigm as a method for inducing a happy mood state and compares the response of euthymic bipolar subjects and healthy controls.Method. The Sense of Hyperpositive Self Scale, the Tellegen positive and negative adjectives, the Global-Local task and a visual analogue scale for measuring positive affect were administered to 15 euthymic bipolar subjects and 19 age-and-sex-matched healthy control subjects before and after they had performed the Go task in a reward paradigm.Results. Significant differences were found between subjects and controls on several measures at each time-point but there were no differences across the groups across time except for the visual analogue scales, where subjects had a more sustained duration in self-reported happiness compared with controls.Conclusions. This pilot study has shown that a positive affect can be induced in bipolar subjects and controls which can be demonstrated by changes in scores on several tasks. However, only the visual analogue scales showed a significant difference between cases and controls over time. Such tests may prove valuable in furthering understanding about the evolution of manic mood states.

Estratégias de intervenção que utilizam exergames que visam o estímulo à prática de atividade física, bem como à redução do tempo em comportamento sedentário, parecem ser caminhos promissores para lidar com o aumento das taxas de obesidade. Este foi o intuito do Projeto de Extensão “Exergaming para a saúde: intervenção para o controle do peso corporal em adolescentes utilizando videogames ativos”, contemplado com fomento do MEC/PROEXT no ano de 2013. O objetivo do estudo foi verificar o efeito de uma intervenção de oito semanas com videogames ativos sobre variáveis relacionadas ao peso corporal de adolescentes. Foi realizado um estudo piloto de intervenção de oito semanas com duração de 60 minutos por sessão, com uso dos exergames. Participaram do estudo oito escolares, com média de idade de 11,5±0,5 anos. Medidas antropométricas antes e após a intervenção foram realizadas. Utilizou-se a estatística descritiva e o teste t pareado, no SPSS 20.0 com nível de significância de p0,05. Observou-se que houve diferença estatisticamente significativa somente na circunferência de cintura (cm) com redução de 2,8 cm (p = 0,028). As demais variáveis analisadas não foram diferentes. O estudo piloto de uma intervenção de oito semanas com videogames ativos demonstrou possibilidade de redução de medidas antropométricas, tais como a circunferência de cintura dos adolescentes. Sugere-se que novos estudos com exergames tenham enfoque neste desfecho em um período mais longo de intervenção e/ou com maior número de sessões durante a semana.ABSTRACT. Intervention for the control of body weight in adolescents using active video games: a pilot study. Intervention strategies that use exergames that aim to stimulate the practice of physical activity, as well as the reduction of the time in sedentary behavior, through promising ways to deal with the increase of obesity rates. This is the way of Extension Project “Exergaming for health: intervention for the control of body weight in adolescents using active video games”, with fomentation of MEC/PROEXT in 2013. The aim of this study was to verify the effect of an eight-week intervention with active video games on variables related to adolescent body weight. An eight-week intervention study with a duration of 60 minutes per session, with use of exergames was performed. Eight schoolchildren participated, with mean age of 11.5±0.5 years. Anthropometric measures before and after the intervention were performed. Descriptive statistics and the non-parametric equivalent of paired t-test were used in SPSS 20.0 with significance level of p0.05. It was observed that there was a significant difference only in waist circumference (cm) with a reduction of 2.8 cm (p = 0.028). The other variables analyzed were not different. The pilot study of an eight-week intervention with active videogames demonstrated the possibility of reducing anthropometric measures, such as the waist circumference of adolescents. We suggested that new studies with exergames focus on this outcome over a longer period of intervention and/or with a larger number of sessions during the week.

ObjectivesThe present study was performed to evaluate the usefulness of serum C-reactive protein (CRP) as an acute phase reactive protein in pet rabbits in clinical practice.MethodsThe CRP level using a rabbit CRP ELISA and white blood cell (WBC) count in pet rabbits (30 healthy controls and 62 with various diseases) were measured in the clinical practice setting. The CRP level and WBC count were measured before and after ovariohysterectomy of a healthy rabbit and a rabbit with uterine adenocarcinoma. The association between the CRP level and mortality in rabbits with various diseases was assessed.ResultsThe CRP level in healthy controls was 0.52±0.82 mg/dl (mean±SD). No age and sex-related differences in neither the CRP level nor WBC count were observed in the healthy control rabbits. The CRP levels in rabbits with gastrointestinal disease (n=22, 11.74±22.89 mg/dl), reproductive and urinary system disease (n=20, 21.19±49.68 mg/dl), dental disease (n=6, 4.87±5.47 mg/dl) and musculoskeletal disease (n=4, 85.66±107.28 mg/dl) were significantly higher than those in healthy controls. The CRP levels in rabbits with neurological disease (n=7, 2.55±1.79 mg/dl) and dermatological disease (n=3, 8.84±7.71 mg/dl) were higher than those in healthy controls, but no significant difference was observed. The WBC counts were not significantly different between rabbits with diseases and healthy controls. Serum samples were collected from two rabbits before and after ovariohysterectomy. In both rabbits, the CRP peaked on postoperative day 1, but no obvious WBC peak was observed. The mortality rate increased as the CRP level increased; the mortality rate was significantly higher in rabbits with a CRP level of ≥100 mg/dl than of <10 mg/dl.ConclusionsThis study indicates that the serum CRP level is useful to determine the disease status, monitor the treatment course and evaluate the prognosis in pet rabbits in clinical practice.

Abstract Background: Recent studies show that oxidative stress is associated with the pathogenesis of schizophrenia. There are two major types of antioxidant systems in vivo, namely enzymatic antioxidants and non-enzymatic antioxidants. This study investigated differences of non-enzymatic antioxidants between schizophrenia patients and healthy controls. Methods: Peripheral UA, ALB, and TBIL of 107 schizophrenic patients in the acute stage and 101 in the remission stage were measured respectively, so were 273 healthy controls. Results: The levels of UA ( P =0.020) and TBIL ( P <0.001) of schizophrenic patients in acute stage were higher than those of healthy controls, while the level of ALB ( P <0.001) was lower. Similar results were detected form schizophrenic patients in the remission stage. Schizophrenic patients in acute stage were divided into antipsychotics-use subgroup (n=56) and antipsychotics-naïve/free subgroup (n=51). The level of UA ( P =0.001) in the antipsychotics-use subgroup was higher than that in the antipsychotics-naïve/free subgroup, while the level of TBIL ( P =0.002) was lower than that in antipsychotics-naïve/free subgroup. 77 schizophrenic patients in the acute stage were followed up, and there was no significant difference in the level of UA before and after treatment, but levels of ALB ( P <0.001) and TBIL ( P <0.001) decreased significantly after the treatment. Conclusion: This study demonstrated that the dysfunction of the peripheral non-enzymatic anti-oxidation system might be involved in the pathogenesis of schizophrenia.

Background: Lifestyle risks for myopia are well known and the disease has become a major global public health issue worldwide. There is a relation between reading, writing, and computer work and the development of myopia. Methods: Within this prospective pilot study in 44 patients aged between 6 and 12 years with myopia we compared possible treatment effects of acupuncture or moxibustion. The diopters of the right and left eye were evaluated before and after the two treatment methods. Results: Myopia was improved in 14 eyes of 13 patients (15.9%) within both complementary methods. Using acupuncture an improvement was observed in seven eyes from six patients out of 22 patients and a similar result (improvement in seven eyes from seven patients out of 22 patients) was noticed in the moxibustion group. The extent of improvement was better in the acupuncture group (p = 0.008 s., comparison before and after treatment); however, group analysis between acupuncture and moxibustion revealed no significant difference. Conclusions: Possible therapeutic aspects with the help of evidence-based complementary methods like acupuncture or moxibustion have not yet been investigated adequately in myopic patients. Our study showed that both acupuncture and moxibustion can improve myopia of young patients. Acupuncture seems to be more effective than moxibustion in treating myopia, however group analysis did not prove this trend. Therefore, further Big data studies are necessary to confirm or refute the preliminary results.

BackgroundThere are few theoretical proposals that attempt to account for the variation in affective processing across different affective states of bipolar disorder (BD). The Interacting Cognitive Subsystems (ICS) framework has been recently extended to account for manic states. Within the framework, positive mood state is hypothesized to tap into an implicational level of processing, which is proposed to be more extreme in states of mania.MethodThirty individuals with BD and 30 individuals with no history of affective disorder were tested in euthymic mood state and then in induced positive mood state using the Question–Answer task to examine the mode of processing of schemas. The task was designed to test whether individuals would detect discrepancies within the prevailing schemas of the sentences.ResultsAlthough the present study did not support the hypothesis that the groups differ in their ability to detect discrepancies within schemas, we did find that the BD group was significantly more likely than the control group to answer questions that were consistent with the prevailing schemas, both before and after mood induction.ConclusionsThese results may reflect a general cognitive bias, that individuals with BD have a tendency to operate at a more abstract level of representation. This may leave an individual prone to affective disturbance, although further research is required to replicate this finding.

BACKGROUND: Leptin, an adipocyte-produced cytokine, interacts with various hormones, including those of the hypothalamic-pituitary-adrenal axis. Fibromyalgia is a syndrome characterized by widespread pain accompanied by tenderness. The pathogenesis involves a disturbance in pain processing and transmission by the central nervous system, leading to a general increase in pain perception.OBJECTIVES: To analyze potential changes in leptin levels among female fibromyalgia patients compared with healthy controls, and to evaluate the changes in leptin levels during treatment.METHODS: Sixteen female fibromyalgia patients were recruited. Patients underwent clinical evaluation, physical examination, including manual dolorimetry, and were evaluated regarding quality of life, pain, fatigue, anxiety and depression. Plasma leptin levels were determined by ELISA. Patients were offered standard treatment for fibromyalgia. Clinical evaluation and leptin determination were repeated after three months.RESULTS: No significant difference was observed between leptin levels among fibromyalgia patients and controls; no significant correlation was observed between leptin levels and clinical parameters reflecting fibromyalgia severity; and no significant change was observed in leptin levels over three months of treatment. These results did not change after adjustment of leptin levels for body mass index values.CONCLUSIONS: The results of the present study do not support the existence of a significant relationship between leptin and fibromyalgia pathogenesis. Increasing the sample size or examining the interaction between leptin and additional hormones/mediators of metabolism and body weight control may yet uncover significant information in this field.

Background Nasal preparation prior to flexible laryngoscopy is a common ENT practice. Co-phenylcaine is increasingly used because it is safe and has both anaesthetic and vasoconstrictive properties. Lidocaine 4% and epinephrine 1:1000 nasal packing is another method used in our department. Methods A prospective case series was performed on eighty-one patients requiring flexible laryngoscopy. Patients were enrolled into either a co-phenylcaine or a lidocaine/epinephrine packing group. Visual analogue scales (VAS) were used to record unpleasantness of nasal preparation and flexible laryngoscopy. Decongestion and ease of endoscope passage were recorded by the doctors. Results Bad taste was statistically significantly worse when using cophenylcaine for nasal preparation ( P = 0.001). However, there was no statistically significant difference in overall unpleasantness from nasal preparation or from subsequent flexible laryngoscopy between the two groups. There was no statistically significant difference in degree of decongestion or ease of endoscope passage between the two groups. Conclusion There is no statistically significant advantage of using cophenylcaine spray over non-proprietary lidocaine 4% and epinephrine 1:1000 nasal packing. However cost and bad taste is less with nasal packing.

Introduction.Th17,γδT, NK, and NKT cells in peripheral blood and serum IL-17 and IL-23 in Takayasu arteritis (TA) were measured and correlated with disease activity.Methods.Th17 (anti-CD3APC, CD4PECy7, and IL-17PE), NKT, NK (anti-CD3APC, CD56FITC), andγδT (anti-CD3FITC andγδTCRAPC) cells were enumerated by flow cytometry in peripheral blood of 30 patients with TA (ACR1990 criteria) and 20 healthy controls, serum IL-17 and IL-23 measured by ELISA. Relation with disease activity (NIH criteria, ITAS2010) was analyzed (using nonparametric tests, median with interquartile range).Results.Mean age of patients was33.47±11.78years (25 females); mean symptom duration was7.1±5.3years. 13 were not on immunosuppressants; 12 were active (ITAS2010 ≥ 4). The percentage of Th17 cells was significantly expanded in TA (patients 2.1 (1.5–3.2) versus controls 0.75 (0.32–1.2);p<0.0001) with no differences in other cell populations. Serum IL-17 and IL-23 (pg/mL) in patients (6.2 (4.6–8.5) and 15 (14.9–26.5), resp.) were significantly higher (p<0.001) than controls (3.9 (3.9–7.3) and undetectable median value, resp.). Subgroup analysis revealed no correlation of Th17 cells, serum IL-17, and IL-23 with disease activity or medications, nor any significant difference before and after medication.Conclusions.There is significant expansion of Th17 cells and elevated serum IL-17 and IL-23 levels in TA patients compared to healthy controls.
