A pilot study to assess the effects of preventing fluid retention in the legs by wearing compression stockings on overnight airway narrowing in mild asthma.

PURPOSE: Nocturnal asthma is a sign of asthma worsening and could be partially due to more fluid drawn into the thorax during sleep by gravitational force and/or pharyngeal collapse in those with obstructive sleep apnea. Wearing compression stockings during the day reduces fluid shift from the legs to the neck overnight. However, the potential effect of wearing compression stockings to reduce fluid accumulation in the leg and to improve nocturnal small airway narrowing in patients with asthma has not been investigated. This study investigates whether reducing leg fluid volume by wearing compression stockings during the day would attenuate small airway narrowing in patients with asthma before and after sleep. METHODS: We enrolled 11 participants with asthma. All participants underwent overnight polysomnography with or without wearing compression stockings for 2 weeks. Before and after sleep, leg fluid volume (LFV) was measured by bioelectrical impedance, and airway narrowing was primarily assessed by respiratory system resistance and reactance at 5 Hz (R5 and X5 respectively) using oscillometry. RESULTS: After 2 weeks of wearing compression stockings, the LFV measured in the evening was reduced (∆ = - 192.6 ± 248.3 ml, p = 0.02), and R5 and X5 improved (∆ = - 0.7 ± 0.9 cmH2O/L/s, p = 0.03 and 0.2 ± 1.4 cmH2O/L/s, p = 0.05 respectively). No changes were observed in the morning. CONCLUSIONS: Preventing fluid retention in the legs by wearing compression stockings for 2 weeks during the day, reduced LFV and airway narrowing in the evening in all participants with asthma, but not in the morning after sleep.

Does Resting Motor Threshold correlate with severity of Alzheimer's disease?

Conflicting results have emerged from studies examining the potential of resting motor threshold (RMT) as a neurophysiological marker for Alzheimer's disease (AD) diagnosis and progression. In this study, we estimated the strength of the association between RMT measurements and severity of cognitive impairment in a relatively large sample (N=128) of clinical trial participants with mild (Clinical Dementia Rating - CDR=1) to moderate (CDR=2) AD. RMT for each participant was determined by applying single-pulse transcranial magnetic stimulation repeated at varying intensities over left and right sides of the primary motor cortex. RMT is the minimum intensity that evoked a visible contralateral involuntary finger twitch and RMT asymmetry is the absolute difference between the left and right RMT measurements. Cognitive impairment was measured with the Montreal Cognitive Assessment (MoCA) and the Alzheimer Disease Assessment Scale - Cognitive (ADAS-Cog) scores. Although the left and right RMT was lower in CDR 2 than in CDR 1 participants, neither RMT nor RMT asymmetry correlated significantly with cognitive test scores. In conclusion, our study in a large sample size does not support the idea that RMT is a sensitive marker of cognitive decline/severity in AD. Clinical Relevance- This study provides evidence that RMT may not be useful for AD progression monitoring.

Visuospatial working memory and attention control make the difference between experts, regulars and non-players of the videogame League of Legends.

Video games have been postulated as an emerging field for studying the cognition-expertise relationship. Despite this, some methodological practices hinder scientific advance (e.g., heterogeneous samples, an ambiguous definition of expertise, etc.). League of Legends (LOL) is a massively played video game with a moderately defined structure that meets the requirements to overcome current study limitations. The aim of this study was to analyze cognitive differences among expert LOL players, regular LOL players, and non-videogame players. A sample of 80 participants was enrolled in three different groups of expertise. Participants were evaluated with behavioral tests of working memory, attention, cognitive flexibility, and inhibition. Kruskal-Wallis tests for group comparison showed that the experts performed significantly better than regular players and non-videogame players in the working memory test. Significant differences were also found between players and non-videogame players in the attention test. Methodological implications for future research in neuroscience and human-computer interaction are discussed.

Association of Obstructive Apnea with Thoracic Fluid Shift and Small Airways Narrowing in Asthma During Sleep.

Rationale: Obstructive sleep apnea (OSA) is highly prevalent among patients with asthma, suggesting a pathophysiological link between the two, but a mechanism for this has not been identified. Hypothesis: Among patients with asthma, those with OSA will have greater overnight increases in thoracic fluid volume and small airways narrowing than those without OSA. Methods: We enrolled 19 participants with asthma: 9 with OSA (apnea-hypopnea index (AHI) ≥10) and 10 without OSA (AHI <10). All participants underwent overnight polysomnography. Before and after sleep, thoracic fluid volume was measured by bioelectrical impedance and small airways narrowing was primarily assessed by respiratory system reactance at 5Hz using oscillometry. Results: Patients with asthma and OSA (OSA group) had a greater overnight increase in thoracic fluid volume by 120.5 mL than patients without OSA (non-OSA group) (164.4 ± 44.0 vs 43.9 ± 47.3 mL, p=0.006). Compared to the non-OSA group, the OSA group had greater overnight decrease in reactance at 5Hz (-1.08 ± 0.75 vs 0.21 ± 0.27 cmH2O/L/s, p=0.02), and overnight increase in reactance area (14.81 ± 11.09 vs -1.20 ± 2.46 cmH2O/L, p=0.04), frequency dependence of resistance (1.02 ± 0.68 vs 0.05 ± 0.18 cmH2O/L/s, p=0.04), and resonance frequency (2.80 ± 4.14 vs -1.42 ± 2.13 cmH2O/L/s, p=0.04). Conclusion: Patients with asthma and co-existing OSA had greater overnight accumulation of fluid in the thorax in association with greater small airways narrowing than those without OSA. This suggests OSA could contribute to worsening of asthma at night by increasing fluid accumulation in the thorax.

Postural Sway Characteristics Are Affected by Alzheimer's Disease.

The vestibular system, responsible for balance, is affected by Alzheimer's disease (AD). In this paper, linear and non-linear balance features were used to assess the postural stability of 13 AD individuals at mild stages in comparison with 16 healthy controls. Utilizing two accelerometers, the anterior-posterior (AP) and medial-lateral (ML) sways were recorded from the T2 vertebrae and lateral malleolus of participants standing on a solid and soft foam surface under both eyes-open and eyes-closed conditions. From the recorded signals, four features were extracted and used for statistical analysis: Number of Position Changes (NPC), Number of Non-Zero Accelerations (NNZA), Katz, and Higuchi fractal dimensions (KFD and HFD, respectively). The results show: 1) postural stability is significantly worse for the eyes-closed compared to eyes-open condition (P<0.05 for all features except HFD) as well as whilst standing on soft foam compared to the solid surface (P<0.05 for all features) in both groups; 2) balance perturbations were larger for AP sway than ML on both solid and foam surfaces in both groups (P<0.05 for NPC and NNZA); and 3) stationary balance is significantly poorer for AD individuals compared to controls (P<0.05 for all features). These observations show that both linear and non-linear characteristics of postural stability data have the potentials to be used as objective diagnostic aids for the detection of AD.

The Relationship between Motivation and Burnout in Athletes and the Mediating Role of Engagement.

The purpose of our research was to analyze the relationship among motivation, burnout, and engagement in sports. Five hundred athletes of both sexes from multiple sports modalities took part, with a mean age of 17.39 years (SD = 4.60). The instruments applied were as follows: Spanish versions of the Sport Motivation Scale (SMS), the Athlete Engagement Questionnaire (AEQ) and the Athlete Burnout Questionnaire (ABQ). Pearson correlations showed that motivation is negatively related to burnout and positively to engagement, while burnout and engagement are inversely related to each other. Through structural equation modeling, it was shown that engagement has a mediating role between motivation and burnout. Furthermore, there are no gender differences in this relationship, although there are differences between athletes who practice individual sports and those who practice collective sports. Encouraging high levels of self-determined motivation can help to increase athletes' degree of engagement and protect them against burnout and sport withdrawal.

Desarrollo moral a través de un programa predeportivo y de valores en alumnos adultos con discapacidad intelectual / Moral development through a sports and values program in adult students with intellectual disabilities

El objetivo del presente trabajo fue incrementar el desarrollo moral en alumnos adultos con discapacidad intelectual, a través de un programa predeportivo y de valores. El programa se llevó a cabo a lo largo de un cuatrimestre de un título dirigido a la inserción sociolaboral de personas con discapacidad intelectual. Participaron 37 alumnos de ambos sexos, de tres promociones consecutivas (n1 = 11; n2 = 12; n3 = 14), entre los 19 y los 37 años (M = 24.49 ± 4.22). Se utilizó la versión española del Moral Competence Test (MCT), que mide los dos componentes del desarrollo moral: la competencia moral y las orientaciones o preferencias morales. Se planificó un diseño cuasiexperimental de cohorte de ciclo institucional recurrente, implicando a tres cohortes evaluadas en tres años consecutivos. Además, para asegurar la equivalencia de los grupos se realizó un estudio acerca de la influencia de variables sociodemográficas y clínicas en el cambio de la competencia moral del alumnado, a través de un diseño ex post facto prospectivo de grupo único. Los resultados mostraron un aumento del desarrollo moral, en sus dos componentes, con significación estadística en el estadio 4 de las orientaciones o preferencias morales

The aim of this study was to increase moral development of the students with intellectual disabilities, through an intervention with values learning and adapted sports. The program was developed in a training course for Social and Labor insertion of People with Intellectual Disability. The sample consisted of 37 students of three consecutive promotions (n1 = 11; n2 = 12; n3 = 14), aged from 19 to 37 years (M = 24.49 ± 4.22). Instrument used was the Spanish version of the Moral Competence Test adapted to intellectual disability (MCT) which measures the two components of moral development through two scores: moral competence and moral orientations/preferences. A quasi-experimental recurrent institutional cycle cohort design was planned. This design involved three cohorts, evaluated in three consecutive years. In addition, to ensure the equivalence of the groups, a study was carried out on the influence of sociodemographic and clinical variables in the change of students' moral competence, through a prospective ex post facto single group design. The results showed an improvement in two components of moral development, with statistically significant differences in stage 4 of moral orienta-tions/preferences

A Novel Program to Improve Cognitive Function in Individuals With Dementia Using Transcranial Alternating Current Stimulation (tACS) and Tutored Cognitive Exercises.

The effects of cognitive exercises on the healthy aging population is controversial. Transcranial alternating current stimulation (tACS) is considered a promising tool for modulating brain oscillation. Research is lacking on its long-lasting cognitive/therapeutic effect. This is the first pilot study to explore the effect of a regimen of cognitive exercises with and without tACS on older adults with dementia. The study groups were 28 individuals (age 56-83 years) enrolled into two groups: Exr Group, who received cognitive exercises only and the Exr + tACS Group who received tACS at 40 Hz simultaneously with cognitive exercises for a period of 4 consecutive weeks, 5 days/week, two 30 min-sessions/day; all the training sessions were tutored. The cognitive exercises were applied using the MindTriggers app. They were assessed at pre and post intervention and also one month after the end of trial (follow-up) with an independent assessment (WMS-IV) as the primary outcome measure. The results show significant cognitive improvement at post-intervention in both groups, while the Exr + tACS protocol lead to superior cognitive improvement at follow-up session. The most important outcomes of this study are: 1) The tutored repeated practice of the MindTriggers app exercises does significantly improve the cognitive functions of older adults with dementia and that that improvement lasts for at least one month after the end of the intervention, and 2) The application of tACS increases the positive effects of cognitive exercises with the positive effect lasting an even longer period of time than exercises alone; in other words we speculate that it may lead to long-term potentiation.

The effect of transcranial alternating current stimulation (tACS) on cognitive function in older adults with dementia.

Recent studies have shown a positive effect of transcranial alternating current stimulation (tACS), a noninvasive brain stimulation technique, on cognitive function of healthy individuals [1]. However, investigation into the effects of tACS on individuals with dementia or mild cognitive impairment (MCI) is lacking. In this pilot study, we investigated the hypothesis that following a regular schedule of challenging brain exercises combined with simultaneous tACS application would improve the working memory and cognitive function of older adults with memory impairments. Further, we explored whether pairing brain exercises with tACS would result in longer-lasting positive effects on cognitive function than brain exercises alone. A total of 17 older adults (12 males, 5 females, 70 ± 7 years), each with a diagnosis of mild to moderate dementia were enrolled in the study. All participants completed brain exercises in the lab on the following schedule: two 30-minute sessions per day, 5 days/week for 4 weeks consecutively. Eleven of the participants received brain exercises paired with tACS application at 40Hz. We evaluated cognitive function of the participants at baseline, post-intervention and 1-month followup using the Wechsler Memory Scale (WMS-IV) as an independent assessment of our brain exercises. Both the non-tACS and tACS groups significantly improved their WMS scores from baseline to post-intervention assessments. Comparison of the post-intervention and 1-month follow-up assessments indicated that the tACS group maintained their improvement significantly better than the non-tACS group.

Basic Psychological Needs, Burnout and Engagement in Sport: The Mediating Role of Motivation Regulation.

The purpose of the present research was to analyze the mediating role of motivational regulation between the satisfaction of basic psychological needs and burnout and engagement in athletes. From different sports 1011 young Spanish athletes participated in the study. Participants completed several measurement instruments concerning: the Basic Needs Satisfaction in Sport Scale, Behavioral Regulation in Sport Questionnaire, Athlete Burnout Questionnaire and Athlete Engagement Questionnaire. The results of structural equation modeling showed that the satisfaction of basic psychological needs has direct effects on burnout and engagement: a negative effect on athlete burnout (-0.49, p < 0.001) and a positive effect on engagement (0.54, p < 0.001). In addition, the satisfaction of basic psychological needs has a partial indirect effect over these variables in the same direction mediated by the self-determined degree of motivation. Thus, low levels of self-regulated motivation are positively related to burnout, but high levels of self-determined motivation are not. The same was observed with engagement, but vice versa: high levels of self-determined motivation are positively related to athlete engagement, but low levels of self-determined motivation are not. The proposed model explained 37% of the variance of burnout and 51% of the variance of engagement.

Osteopathic manipulative treatment combined with exercise improves pain and disability in individuals with non-specific chronic neck pain: A pragmatic randomized controlled trial.

PURPOSE: To determine effectiveness of osteopathic manipulative treatment combined with stretching and strengthening exercises in the cervical region on pain and disability in individuals with non-specific chronic neck pain. METHODS: 90 adults with non-specific chronic neck pain were randomized to either exercises group (EG, n = 45) or osteopathic manipulative treatment associated with exercises group (OMT/EG, n = 45). The primary outcomes were obtained by the use of Numeric Pain-Rating Scale (NPRS), Pressure Pain Threshold (PPT) and Neck Disability Index (NDI). Secondary outcomes included range of motion (ROM) for cervical spine rotation, Fear-Avoidance Beliefs Questionnaire Work/Physical Activity (FABQ-W/PA) and Pain-self efficacy at two different moments: baseline and 4 weeks after the first treatment. Techniques and dosages of OMT were selected pragmatically by a registered osteopath. Generalized Estimating Equations model (GEE), complemented by the Least Significant Difference (LSD) and the intention-to-treat analysis, was used to assess the clinical outcomes. RESULTS: Analysis with GEE indicated that OMT/EG reduced pain and disability more than the EG alone after 4 weeks of treatment with statistically significant difference (p < 0,05), as well as cervical active rotation was significantly improved (p = 0.03). There were no between-group differences observed in Pressure Pain Threshold (PPT) measure, Fear-Avoidance Beliefs Questionnaire and Pain-self efficacy. CONCLUSION: The association between OMT and exercises reduces pain and improves functional disability more than only exercise for individuals with non-specific chronic neck pain.

Acute effect of photobiomodulation using light-emitting diodes (LEDs) on baroreflex sensitivity during and after constant loading exercise in patients with type 2 diabetes mellitus.

To evaluate the photobiomodulation (PBM) effect on the cardiovascular autonomic control, analyzed by baroreflex sensitivity (sequence method), during constant load exercise and recovery in diabetic men, we evaluated 11 men with type 2 diabetes (DM2) (40-64 years). The constant workload exercise protocol (TECC) was performed on two different days, 14 days apart from each other, to guarantee PBM washout period. After PBM by light-emitting diode (LED) irradiation (150 J or 300 J or placebo), 10 min of rest (REST) was performed. After this period, the volunteer was positioned on a cycloergometer to start the test (1-min rest, 3-min free-load heating, 6-min constant workload-EXERCISE, 6-min free-load cool-down, 1-min rest) followed by a sitting period of 10 min (RECOVERY). The constant workload corresponded to 80%VO2GET (gas exchange threshold) identified by a previous cardiopulmonary exercise test (CPET). PBM was applied in continuous mode, contact technique, bilaterally, on both femoral quadriceps and gastrocnemius muscle groups. The electrocardiogram R-R intervals (BioAmp FE132) and the peripheral pulse pressure signals (Finometer PRO) were collected continuously throughout the protocol. Stable sequences of 256 points were chosen at REST, EXERCISE, and RECOVERY. The baroreflex sensitivity (BRS) was computed in time domain according to the sequence method (αseq). The comparison between therapies (150 J/300 J/placebo) and condition (REST, EXERCISE, and RECOVERY) was performed using the ANOVA two-way repeated measures test. There was no interaction between therapy and conditions during the TECC. There was only the condition effect (p < 0.001), showing that the behavior of αseq was similar regardless of the therapy. Photobiomodulation with 150 J or 300 J applied previously to a moderate-intensity TECC in DM2 was not able to promote cardiovascular autonomic control changes leading to an improvement in BRS.

Effects of light-emitting diode therapy (LEDT) on cardiopulmonary and hemodynamic adjustments during aerobic exercise and glucose levels in patients with diabetes mellitus: A randomized, crossover, double-blind and placebo-controlled clinical trial.

The aim of this study was to evaluate the acute effects of light-emitting diode therapy (LEDT) on cardiopulmonary adjustments and muscle oxygenation dynamics during transition to moderate exercise, as well as in glucose and lactate levels in patients with type 2 diabetes mellitus (T2DM). Sixteen individuals with T2DM (age 55.1±5.4 years) performed four separate tests receiving LEDT or placebo in random order, at intervals of at least 14 days. A light-emitting diode array (50GaAIAs LEDs, 850nm, 75mW per diode) was used to perform LEDT bilaterally on the quadriceps femoris and triceps surae muscles for 40s at each site. After, a moderate cycling exercise was performed and oxygen uptake, muscular deoxyhemoglobin, heart rate and cardiac output were measured. Lactate and glucose levels were measured before LEDT/placebo and after the exercise. The LEDT decreased the glucose levels after the exercise compared with values before LEDT (173.7±61.0 to 143.5±53.5 mg/dl, P=0.02) and it did not affect the cardiopulmonary and hemodynamic adjustments in exercise, as well as lactate levels in both groups. In conclusion, the LEDT in combination with moderate exercise acutely decreased the glucose levels in men with T2DM.

The mediating role of sport self-motivation between basic psychological needs satisfaction and athlete engagement / El rol mediador de la motivación autodeterminada entre la satisfacción de las necesidades psicológicas básicas y el engagement deportivo

BACKGROUND: Engagement could constitute a frame of reference for promoting positive experiences in sport, hence the importance of learning about what precedes it in order to promote its development. This study was conducted to examine the role of self-motivation as a mediator between basic psychological needs satisfaction and athlete engagement. METHOD: A sample of 426 male and female athletes from different sports were asked to complete three questionnaires measuring each of the study variables: The Basic Needs Satisfaction in Sport Scale, the Behavioral Regulation in Sport Questionnaire and the Athlete Engagement Questionnaire. A structural relationships model between the constructs analyzed was specified and implemented. RESULTS: High levels of self-motivation increased levels of athlete engagement and vice versa. CONCLUSION: Basic psychological needs satisfaction has a direct positive effect on athlete engagement and in turn, an indirect effect mediated by athletes' self-motivation

ANTECEDENTES: el engagement es un marco de referencia para la promoción de experiencias positivas en el deporte, de ahí la importancia de conocer sus antecedentes con el objetivo de promover su desarrollo. El presente estudio se realizó con el propósito de examinar el papel de la motivación autodeterminada como mediadora entre la satisfacción de las necesidades psicológicas básicas y el engagement de los deportistas. MÉTODO: se utilizó una muestra de 426 deportistas, hombres y mujeres, de diferentes modalidades deportivas a los que les pidió que respondieran a tres cuestionarios que medían cada una de las variables de estudio: Basic Needs Satisfaction in Sport Scale, Behavioral Regulation in Sport Questionnaire y Athlete Engagement Questionnaire. Se especificó un modelo de relaciones estructurales entre los constructos analizados. RESULTADOS: niveles altos de motivación autodeterminada incrementan los niveles de engagement del deportista mientras que niveles bajos de motivación autodeterminada los debilitan. CONCLUSIÓN: existe un efecto directo de tipo positivo de la satisfacción de las necesidades psicológicas básicas de los deportistas sobre su grado de engagement deportivo y a la vez un efecto indirecto mediado por su motivación autodeterminada

Effects of physical exercise training on nocturnal symptoms in asthma: Systematic review.

INTRODUCTION: Nocturnal worsening of asthma symptoms is a common feature of asthma. Physical exercise training improves general asthma control; however, there is no evidence showing the effects of physical exercise on nocturnal asthma symptoms. Indeed, asthma patients with daytime and nighttime symptoms are physiologically different, and thus the effects of physical exercise on asthma may also be different in these two groups. The objective of this systematic review is to explore the effects of physical exercise on nocturnal asthma symptoms. METHODS: Searches were conducted in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL and SPORTdiscus (last search on November 2017). Authors from studies that did not report nocturnal symptoms but used questionnaires and/or diaries were contacted for detailed information. Studies that provided results on nocturnal symptoms before and after physical activity intervention were included. Prevalence of nocturnal symptoms was calculated for each study from the percentage of study participants with nocturnal symptoms before and after intervention. RESULTS: Eleven studies were included (5 with children and 6 with adults). The prevalence of nocturnal symptoms at baseline ranged from 0% to 63% among children and from 50-73% among adults. In children and adults with nocturnal asthma, aerobic physical exercise reduced the prevalence and frequency of nocturnal symptoms. CONCLUSIONS: Aerobic physical exercise improves nocturnal asthma in children and adults by reducing the prevalence and frequency of nocturnal symptoms. Physical exercise training could be used with conventional treatments to improve quality of life and asthma control in patients with nocturnal worsening of asthma.

Preliminary Empirical Validation of the "Basic Needs Satisfaction in Sport Scale" With a Sample of Spanish Athletes.

The theory of self-determination establishes the existence of three basic psychological needs (autonomy, competence, and relationship). If these needs are satisfied, optimal personal well-being will be achieved. The Basic Needs Satisfactions in Sport Scale (BNSSS) is a measurement developed to evaluate these needs within the sporting context. The BNSSS measures the satisfaction of the three basic psychological needs through 20 items distributed in five dimensions: autonomy-choice, autonomy-volition, autonomy-perceived locus of internal causality, competence, and relatedness. The purpose of this study is to validate a Spanish version of the BNSSS. The sample were 441 team athletes with a mean age of 17.46 (SD = 3.59), which 46.5% were men and the remaining percentage (53.5%) were women. After a standardised data collection, confirmatory factor analysis and invariance analyses were performed, as well as composite reliability. The obtained version showed a good overall fit of the model and values of composite reliability higher to 0.70. Therefore, a useful tool for assessing basic psychological needs in team sports was obtained.

Tratamiento Cognitivo-conductual de un Caso de Estrés Postraumático por Accidente Ferroviario. ¿Éxito Terapéutico o Evitación? / Cognitive-behavior treatment in a case of post traumatic stress after a train accident. Therapeutic success or avoidance?

Se describe el caso clínico de una mujer de 53 años con trastorno de estrés postraumático (TEPT), a raíz de un accidente ferroviario en Galicia (España) en julio 2013. El accidente le supuso diferentes lesiones e intervenciones quirúrgicas. El impacto a nivel psicológico aparece de forma demorada, presentando, además de sintomatología TEPT, alta ansiedad, síntomas depresivos y alta irritabilidad. En el tratamiento se aplicó "exposición prolongada" enmarcada en un tratamiento cognitivo-conductual más amplio, en el que se incluyó reestructuración cognitiva y entrenamiento en regulación emocional, para abordar las interpretaciones disfuncionales que favorecían la aparición de la ira. Se describe la aplicación del tratamiento y las principales dificultades encontradas, principalmente la evitación de la exposición al recuerdo del trauma y la solicitud de la paciente del cese anticipado del tratamiento. Se presentan los resultados, incluyendo los seguimientos a 1, 3, 6 y 12 meses, y se discute la evolución de la paciente

This paper presents the case of a 53-year old woman with posttraumatic stress disorder (PTSD) after a train accident in Galicia (Spain) in July, 2013. The accident caused the patient several injuries and surgical interventions. The psychological impact is delayed and consists of PTSD symptoms, besides high anxiety, depression symptoms, and high anger. The treatment involved Prolonged Exposure into a broader cognitive-behavior therapy that included cognitive restructuring and training in emotional regulation to treat dysfunctional cognitive responses that promoted anger. The article describes the implementation of the treatment and the main difficulties encountered, namely, the avoidance of exposure to trauma memories and the premature end of the treatment at patient's request. We present the results of the treatment, including 1, 3, 6, and 12 months follow-ups and discuss patient's progression
