    Background: Noncardiac chest pain has a high prevalence and is associated with reduced quality of life, anxiety, avoidance of physical activity, and high societal costs. There is a lack of an effective, low-cost, easy to distribute intervention to assist patients with noncardiac chest pain. Objective:In this study, we aimed to investigate the effectiveness of internet-based cognitive behavioral therapy with telephone support for noncardiac chest pain. Methods: We conducted a randomized controlled trial, with a 12-month follow-up period, to compare internet-based cognitive behavioral therapy to a control condition (treatment as usual). A total of 162 participants aged 18 to 70 years with a diagnosis of noncardiac chest pain were randomized to either internet-based cognitive behavioral therapy (n=81) or treatment as usual (n=81). The participants in the experimental condition received 6 weekly sessions of internet-based cognitive behavioral therapy. The sessions covered different topics related to coping with noncardiac chest pain (education about the heart, physical activity, interpretations/attention, physical reactions to stress, optional panic treatment, and maintaining change). Between sessions, the participants also engaged in individually tailored physical exercises with increasing intensity. In addition to internet-based cognitive behavioral therapy sessions, participants received a brief weekly call from a clinician to provide support, encourage adherence, and provide access to the next session. Participants in the treatment-as-usual group received standard care for their noncardiac chest pain without any restrictions. Primary outcomes were cardiac anxiety, measured with the Cardiac Anxiety Questionnaire, and fear of bodily sensations, measured with the Body Sensations Questionnaire. Secondary outcomes were depression, measured using the Patient Health Questionnaire; health-related quality of life, measured using the EuroQol visual analog scale; and level of physical activity, assessed with self-report question. Additionally, a subgroup analysis of participants with depressive symptoms at baseline (PHQ-9 score ≥5) was conducted. Assessments were conducted at baseline, posttreatment, and at 3- and 12-month follow-ups. Linear mixed models were used to evaluate treatment effects. Cohen d was used to calculate effect sizes. Results: In the main intention-to-treat analysis at the 12-month follow-up time point, participants in the internet-based cognitive behavioral therapy group had significant improvements in cardiac anxiety (–3.4 points, 95% CI –5.7 to –1.1; P=.004, d=0.38) and a nonsignificant improvement in fear of bodily sensations (–2.7 points, 95% CI –5.6 to 0.3; P=.07) compared with the treatment-as-usual group. Health-related quality of life at the 12-month follow-up improved with statistical and clinical significance in the internet-based cognitive behavioral therapy group (8.8 points, 95% CI 2.8 to 14.8; P=.004, d=0.48) compared with the treatment-as-usual group. Physical activity had significantly (P<.001) increased during the 6-week intervention period for the internet-based cognitive behavioral therapy group. Depression significantly improved posttreatment (P=.003) and at the 3-month follow-up (P=.03), but not at the 12-month follow-up (P=.35). Participants with depressive symptoms at baseline seemed to have increased effect of the intervention on cardiac anxiety (d=0.55) and health-related quality of life (d=0.71) at the 12-month follow-up. In the internet-based cognitive behavioral therapy group, 84% of the participants (68/81) completed at least 5 of the 6 sessions. Conclusions: This study provides evidence that internet-based cognitive behavioral therapy with minimal therapist contact and a focus on physical activity is effective in reducing cardiac anxiety and increasing health related quality of life in patients with noncardiac chest pain.publishedVersio

    The detection of water pipeline leakage is important to ensure that water supply networks can operate safely and conserve water resources. To address the lack of intelligent and the low efficiency of conventional leakage detection methods, this paper designs a leakage detection method based on machine learning and wireless sensor networks (WSNs). The system employs wireless sensors installed on pipelines to collect data and utilizes the 4G network to perform remote data transmission. A leakage triggered networking method is proposed to reduce the wireless sensor network’s energy consumption and prolong the system life cycle effectively. To enhance the precision and intelligence of leakage detection, we propose a leakage identification method that employs the intrinsic mode function, approximate entropy, and principal component analysis to construct a signal feature set and that uses a support vector machine (SVM) as a classifier to perform leakage detection. Simulation analysis and experimental results indicate that the proposed leakage identification method can effectively identify the water pipeline leakage and has lower energy consumption than the networking methods used in conventional wireless sensor networks

    Background Little is known about the psychological prerequisites for weight loss maintenance after bariatric surgery. A first step in investigating whether existing knowledge of conservative weight loss treatment is applicable for lifestyle interventions postoperatively is to compare specific psychological characteristics at baseline. The aim of this study was to compare patients scheduled for bariatric surgery with patients receiving conservative treatment for morbid obesity on measures of behavioral and psychosocial characteristics considered predictors of their adoption of and adherence to long-term lifestyle recommendations. Methods Baseline clinical and questionnaire data from the prospective “Oslo Bariatric Surgery Study” were used to examine potential differences between bariatric surgery patients (n = 301) and patients receiving conservative weight loss treatment (n = 261). Results The surgical group was characterized by their younger age (43.8 vs. 46.2 years, p <0.01), higher percentage of women (79.1 vs. 70.1 %, p <0.05), and higher Body Mass Index (BMI; 45.0 vs. 41.9 kg/m2, p <0.001). A multiple logistic regression analysis, adjusting for group differences in BMI, gender, and age, showed that the surgical group had higher self-efficacy (Odds ratio; OR = 3.44, 95 % Confidence interval; CI 1.65, 7.14), more positive outcome expectations (OR = 1.53, 95 % CI 1.23, 1.89), and plans that were more explicit for changing their eating behaviors (OR = 1.80, 95 % CI 1.06, 1.93). The surgical patients were also less ready to change physical activity levels (OR = 0.59, 95 % CI 0.48, 0.73), had tried more types of unhealthy weight loss methods in the past (OR = 1.16, 95 % CI 1.01, 1.33), drank soda more frequently (OR = 1.24, 95 % CI 1.02, 1.50), had fewer binge eating episodes (OR = 0.38, 95 % CI 0.20, 0.71), and had more depressive symptoms (OR = 1.19, 95 % CI 1.09, 1.29). Conclusions Patients opting for bariatric surgery had more positive expectations of the treatment outcomes and stronger beliefs in their ability to achieve these outcomes. Those starting conservative treatment had stronger beliefs in readiness to change physical activity levels. Future studies should explore the effect of interventions for bariatric surgery patients, promoting postoperative physical activity and stress realistic outcome expectations. The potential effects of incorporating this knowledge in intervention strategies remain to be explored

    Background The long-term prognosis after cognitive behavioral therapy (CBT) in outpatient groups for panic disorder and agoraphobia is not well known. The purpose of this study was to assess long-term outcomes in terms of psychological health, health-related quality of life (HRQoL), quality of life (QoL) and treatment satisfaction after CBT for panic disorder and agoraphobia. Methods The sample consisted of 68 patients (61% response rate), who were assessed at pretreatment; at the start and end of treatment; and after 3 months, after 1 year, and over the long term (M = 24 years; SD = 5.3; range: 12 to 31 years). The main outcome was the total score on the Phobic Avoidance Rating Scale (PARS-total). At long-term follow-up, HRQoL was measured with the RAND-12 questionnaire, and QoL was measured with two questions from the “Study on European Union Statistics on Income and Living Conditions”. Patient experiences and treatment satisfaction were assessed by the Generic Short Patient Experiences Questionnaire. A marginal longitudinal model was applied to study the main outcome. Results The effect size of the long-term change (mean change/ pooled SD) in the PARS-total score was (− 1.6, p < 0.001) and was stable over time. A PARS-total score reduction of 50% was found in 98% of patients at the long-term follow-up. The patients’ HRQoL and QoL were similar to the expected scores for the general Norwegian population. Of the patients, 95% reported high to very high satisfaction with the CBT, and 93% reported large treatment benefits. Conclusions To the best of our knowledge, this study has the longest follow-up after group CBT for panic disorder and agoraphobia, showing a good prognosis in ≥93% of the participating patients

    No full text
    Introduction and Aims: Novel treatments for substance use disorders are needed. Acute bouts of exercise can improve mood states in non‐clinical populations, but effects in those with poly‐substance dependence are understudied. We examined the feasibility and short‐term effects of three types of exercise on drug cravings, self‐esteem, mood and positive/negative affect in nine poly‐drug‐dependent inpatients. Design and Methods: Using a cross‐over design, changes in the four study outcomes were assessed immediately before exercise and on four separate occasions post‐exercise (immediately after, then at 1, 2 and 4 h post‐exercise) enabling patterns of change over time (analysis of covariance) to be observed. Results: Participants were willing and able to engage in different non‐laboratory based exercises. Football was associated with non‐significant short‐term reductions in drug cravings. A similar trend was seen for circuit‐training, but not walking. Football and circuit‐training were associated with brief improvements in mood and positive/negative affect. No adverse events were reported. Discussion and Conclusions: Football, circuit training and walking are feasible therapeutic activities for inpatients with poly‐substance dependence. Controlled trials are needed to determine the long‐term effects of these activities

    Effects of acute exercise on drug craving, self-esteem, mood, and affect in adults with polysubstance use disorder: Protocol for a multicenter randomized controlled trial

    No full text
    Background: Novel treatments for substance use disorders are needed. Acute bouts of exercise can improve mood states and craving in nonclinical populations. Exercise effects in those with polysubstance dependence are understudied; controlled trials are needed. Objective: This protocol describes a clinical study examining the short-term psychological effects of 2 types of physical activity, soccer and circuit training, in patients with substance use disorders. Effects will be compared with a nonexercise control group. Specific aims are to investigate whether there are differences between the activities and the duration of changes. Methods: This study is a short-term multicenter randomized control trial with a crossover design. Patients consecutively admitted to 4 inpatient treatment centers were invited to participate in 3 conditions, each lasting 45 minutes, within one week. The order of the conditions was randomized. There were a total of 5 assessments, taken at baseline, immediately before each condition, immediately after each condition, and 1, 2, and 4 hours postintervention, enabling patterns of change over time to be observed. Psychological effects were assessed with self-report questionnaires, which included scales for craving, state anxiety, positive and negative affect, self-esteem, and mood. Exercise intensity was assessed with the Borg Rating of Perceived Exertion scale and a heart rate monitor (Polar M200; Polar Electro Ltd). Cortisol was assessed in saliva before and 4 hours after the intervention. Results: A total of 39 patients were included in the study. Data collection was completed in 2019. Conclusions: We anticipate larger improvements in the intervention groups than among controls, indicating positive psychological effects during and after exercise. The study will add clinically relevant information about the short-term psychological effects of exercise in the treatment of substance use disorders, using activities that are easily accessible in different clinical settings

    Nearly half of patients with non-cardiac chest pain (NCCP) experience significant complaints after a negative cardiac evaluation, at considerable costs for society. Due to the lack of treatment capacity and low interest for psychological treatment among patients with somatic complaints, only a minority receive effective treatment. The aim of this study was to assess the feasibility and usefulness of internet-assisted cognitive behavioural therapy (I-CBT), including encouragement of physical activity for this condition. Ten patients with NCCP received a six-session I-CBT intervention with minimal support from a therapist. Questionnaires assessing cardiac anxiety, fear of bodily sensations, depression, interpretation of symptoms, frequency of chest pain and impact of chest pain symptoms were collected at baseline, post-treatment and at 3-month follow-up. Semi-structured interviews employing a phenomenological hermeneutic approach assessed the participants’ experience of the intervention. Quantitative results showed clear improvements in several measures both at end of treatment and at 3-month follow-up. The retention rate was 100% and client satisfaction was high. The intervention was feasible to implement in a cardiac setting. This setting made it easier for patients to accept a psychological approach. Qualitative interviews revealed that the participants felt respected and taken care of, and they obtained a better understanding of their chest pain and how to cope with it. This pilot study yielded promising results regarding feasibility, clinical effect and patient satisfaction from a brief I-CBT intervention for NCCP in a cardiac setting. These results indicate that a randomized controlled trial with a larger sample size is warranted

    Introduction There is strong evidence that postpartum depression is associated with adverse health effects in the mother and infant. Few studies have explored associations between physical activity in pregnancy and postpartum depression. We aimed to investigate whether physical activity during pregnancy was inversely associated with postpartum depressive symptoms, PPDS in a multiethnic sample. Method Population-based, prospective cohort of 643 pregnant women (58% ethnic minorities) attending primary antenatal care from early pregnancy to postpartum in Oslo between 2008 and 2010. Data on demographics and health outcomes were collected during standardized interviews. PPDS was defined by a sum score ≥10 from the Edinburgh Postnatal Depression Scale (EPDS), 3 months after birth. Physical activity was recorded with Sense Wear™ Pro3 Armband (SWA) in gestational week 28 and defined as moderate-to-vigorous intensity physical activity (MVPA) accumulated in bouts ≥10 min. Results Women who accumulated ≥150 MVPA minutes/week had significantly lower risk (OR = 0.2, 95% CI: 0.06–0.90), for PPDS compared to those who did not accumulate any minutes/week of MVPA, adjusted for ethnic minority background, depressive symptoms in the index pregnancy and self-reported pelvic girdle syndrome. The results for MVPA persisted in the sub-sample of ethnic minority women. Limitations Numbers of cases with PPDS were limited. The SWA does not measure water activities. Due to missing data for SWA we used multiple imputations. Conclusion Women meeting the physical activity recommendation (>150 MVPA min/week) during pregnancy have a lower risk of PPDS compared to women who are not active during pregnancy
