Individual Human Metabolic Phenotype Analyzed by (1)H NMR of Saliva Samples.

Saliva is an important physiological fluid that contains a complex mixture of analytes that may produce a characteristic individual signature. In recent years, it has been demonstrated that urine possesses a clear signature of the individual metabolic phenotype. Here NMR-based metabolomics was employed to analyze saliva from 23 healthy volunteers. About six saliva samples were collected daily from each individual for 10 consecutive days: 7 days in a real-life situation (days 1-7, Phase I) and 3 days (days 8-10, Phase II) under a standardized diet plus a physical exercise program at day 10. The result is the first demonstration of the existence of an individual metabolic phenotype in saliva. A systematic comparative analysis with urine samples from the same collection scheme demonstrates that the individual phenotype in saliva is slightly weaker than that in urine but less influenced by diet.

Significant decrease of subcutaneous body fat during tube-weaning from enteral feeding.

BACKGROUND: The aim of this paper was to evaluate anthropometry and subcutaneous body fat on long-term enterally-fed children during tube weaning through a prospective cohort study with a pre-post-test design. METHODS: The LIPOMETER, an optical device, was used to measure the thickness of subcutaneous adipose tissue (SAT) layers (in mm). The specification of 15 evenly-distributed body sites allows for a precise measurement of subcutaneous body fat distribution, known as subcutaneous adipose tissue topography (SAT-Top). Anthropometry and SAT-Top were determined in long-term enterally fed children in the pre- and post-tube weaning phase of a 3-week tube weaning program. The results of the SAT-Top measurements are presented on three levels: 15 body sites, four body regions and SAT-total. RESULTS: The sample size consisted of 30 long-term tube-fed children (13 girls and 17 boys). Both sexes demonstrated a clear decrease of anthropometry and subcutaneous body fat during tube weaning. Girls lost -26.1 mm, -30.7%, (P=0.002) of their initial fat mass and boys -12.5 mm, -18.4%, (P<0.001). In general, girls had thicker SAT layers in all SAT-Top measurements and a higher reduction of subcutaneous body fat during the intervention. At the end of the tube weaning program girls and boys demonstrated similar results of subcutaneous body fat on the three observed levels: 15 body sites, four body regions and SAT-total. Upon discharge, total subcutaneous body fat of girls and boys was 58.9 mm and 55.5 mm, respectively. CONCLUSION: This study presents a basic documentation of changes in anthropometry and subcutaneous body fat during tube weaning and could potentially be used to help create guidelines for safe tube weaning.

EEG neurofeedback effects in the treatment of adolescent anorexia nervosa.

A pre-post design including 22 females was used to evaluate the effectiveness of neurofeedback in the treatment of adolescent anorexia nervosa. Resting EEG measures and a psychological test-battery assessing eating behavior traits, clinical symptoms, emotionality, and mood were obtained. While both the experimental (n = 10) and control group (n = 12) received their usual maintenance treatment, the experimental group received 10 sessions of individual alpha frequency training over a period of 5 weeks as additional treatment. Significant training effects were shown in eating behavior traits, emotion regulation, and in relative theta power in the eyes closed condition. Although the results are limited due to the small sample size, these are the first empirical data demonstrating the benefits of neurofeedback as a treatment adjunct in individuals with anorexia nervosa.

Acute Physiological Responses to Short- and Long-Stage High-Intensity Interval Exercise in Cardiac Rehabilitation: A Pilot Study.

Despite described benefits of aerobic high-intensity interval exercise (HIIE), the acute responses during different HIIE modes and associated health risks have only been sparsely discovered in heart disease patients. Therefore, the aim of this study was to investigate the acute responses for physiological parameters, cardiovascular and inflammatory biomarkers, and catecholamines yielded by two different aerobic HIIE protocols compared to continuous exercise (CE) in phase III cardiac rehabilitation. Eight cardiac patients (7 with coronary heart disease, 1 with myocarditis; 7 males, 1 female; age: 63.0 ± 9.4 years; height: 1.74 ± 0.05 m; weight: 83.6 ± 8.7 kg), all but one treated with ß-blocking agents, performed a maximal symptom-limited incremental exercise test (IET) and three different exercise tests matched for mean load (Pmean) and total duration: 1) short HIIE with a peak workload duration (tpeak) of 20 s and a peak workload (Ppeak) equal to the maximum power output (Pmax) from IET; 2) long HIIE with a tpeak of 4 min, Ppeak was corresponding to the power output at 85 % of maximal heart rate (HRmax) from IET; 3) CE with a target workload equal to Pmean of both HIIE modes. Acute metabolic and peak cardiorespiratory responses were significantly higher during long HIIE compared to short HIIE and CE (p < 0.05) except HRpeak which tended to be higher in long HIIE than in short HIIE (p = 0.08). Between short HIIE and CE, no significant difference was found for any parameter. Acute responses of cardiovascular and inflammatory biomarkers and catecholamines didn't show any significant difference between tests (p > 0.05). All health-related variables remained in a normal range in any test except NT-proBNP, which was already elevated at baseline. Despite a high Ppeak particularly in short HIIE, both HIIE modes were as safe and as well tolerated as moderate CE in cardiac patients by using our methodological approach. Key pointsHigh-intensity interval exercise (HIIE) with short peak workload durations (tpeak) induce a lower acute metabolic and peak cardiorespiratory response compared to intervals with long tpeak despite higher peak workload intensities and identical mean load. No significant difference for any physiological parameter was found between short HIIE and CE.Between short HIIE, long HIIE, and CE, no significant difference was found in the increase (or decrease, respectively,) of health related markers such as cardiovascular biomarkers, catecholamines, or inflammatory parameters during exercise.During all exercise modes, all risk markers remained in a normal range except for NT-proBNP which was, however, already elevated at baseline.Short HIIE, long HIIE, and CE were safely performed by patients with CHD or myocarditis in cardiac rehabilitation by using our methodological approach to exercise prescription. This approach included the prescription of exercise intensities with respect to LTP1, LTP2, and Pmax as well as a conscious setting of Pmean at a moderate level (80 % of PLTP2). Importantly, all exercise modes were matched for Pmean and exercise duration in order to enable a comparison of the three protocols.

Body fat distribution and associations with metabolic and clinical characteristics in bipolar individuals.

Overweight and obesity differentially affect bipolar disorder (BD) and are associated with a poorer prognosis. Herein, we sought to evaluate body fat distribution in a well-characterized BD sample. Anthropometric measures (i.e., body mass index, waist-to-hip ratio, waist-to-height ratio, waist circumference, hip circumference, and lipometry) of 100 BD individuals were compared with data of 57 matched mentally healthy controls. Additionally, fasting serum parameters including metabolic parameters and monoamines were analyzed. Findings indicate that similar to US BD cohorts, Austrian patients exhibit an increased central body fat accumulation (i.e., higher subcutaneous adipose tissue at upper abdomen) accompanying with the harmful IDF-defined metabolic syndrome. In addition, positive associations between epinephrine as well as staging and fat parameters were detected.

Subcutaneous Adipose Tissue Topography in Long-Term Enterally Fed Children and Healthy Controls.

In the context of enteral feeding in children the influence on growth and the question of fat resorption is of great interest. We, therefore, measured the thickness of subcutaneous body fat in a sample of long-term enterally fed toddlers and healthy controls. In 33 long-term enterally fed toddlers (10 girls, 23 boys) and 275 healthy controls (128 girls, 147 boys) subcutaneous body fat was measured by means) of the optical device Lipometer. All participants were divided into three age groups (infants, toddlers and children). The height (p=0. 014, -11.7 cm, -12.5%) and weight (p=0.012, -3.0 kg, -21.9%) of long-term enterally fed female toddlers were significantly lower than healthy controls, while male enterally fed toddlers had lower values in all anthropometric measures compared to healthy controls: height (p=0.003, -8.0 cm, -8.4%), weight (p<0.001, -3.5 kg, -24.8%), BMI (p=0.004, -1.3 BMI), Z-score BMI (p=0.001, -1.2 Z-score BMI), upper arm circumference (p<0.001, -1.6 cm, -10.1%) and waist circumference (p<0.001, -6.2 cm, -12.5%). Tube fed toddlers showed a similar body fat distribution when compared to healthy controls, but demonstrated significantly lower values of anthropometric measurements. The results indicate that long-term enterally fed children have ample fat stores but lack physical development.

Caliper vs. Lipometer--Comparing Two Methods of Subcutaneous Body Fat Measurement by Bland-Altman Diagrams.

Skinfold Calipers are widely used to obtain subcutaneous adipose tissue thickness because of its non-invasive, simple and inexpensive technique. Nevertheless, Caliper skinfold thicknesses have the disadvantage of measuring compressed adipose tissue and double layers of skin, which might reduce the precision of these results. In contrast, the computerized optical device Lipometer was developed to permit a quick, precise and non-invasive determination of non-compressed mono layers of subcutaneous adipose tissue thickness. In the present paper we investigate the hypothesis that Caliper skinfold thicknesses are significantly different from subcutaneous adipose tissue thicknesses in mm, which can be measured by Lipometer. Caliper and Lipometer results were obtained from 371 Estonian boys aged between 9.0 and 12.8 years. Measurements were performed at six different body sites: triceps, biceps, upper back, upper abdomen, hip and front thigh. Caliper measurements were systematically higher than Lipometer results in a range between 1.2 mm (hip) and 11.08 mm (front thigh). The limits of agreement analysis provided intervals from 7.5 mm (biceps) up to 30.14 mm (front thigh). Comparing Caliper and Lipometer results very low measurement agreement was found. The two methods provided very poor interchangeability.

Motivational processing of food cues in anorexia nervosa: a pilot study.

Current literature suggests an increased attentional bias toward food stimuli in eating-disordered individuals compared to healthy controls. In line with these research efforts, the present study aims to investigate the processing of food stimuli (enriched by emotional stimuli) between patients diagnosed for anorexia nervosa (AN) and healthy controls by means of electroencephalography. Twenty-two female adolescents (eleven AN patients vs. eleven healthy controls) were investigated. Positive event-related potentials "P300" and "late positive potential" (LPP) reflecting attentional processing (caused by motivationally relevant stimuli) were investigated during passive viewing of the food cue picture stream. This method was used for the first time in a sample of individuals with AN. As a main result, AN patients exhibited a higher amount of attentional bias in P300 and LPP, while watching food stimuli. Moreover, AN patients rated food stimuli as less pleasant. For a conclusion, there is substantial evidence pointing to an abnormal attentional brain reactivity to food pictures in AN. Therefore, food stimuli seem to be more motivationally relevant for AN patients than for healthy controls. By broadening existing knowledge, these findings might bear some implications for the treatment for AN. However, further research is recommended in order to confirm the results coming from rather limited data.

A measure of obesity: BMI versus subcutaneous fat patterns in young athletes and nonathletes.

Although the body mass index (BMI, kg/m2) is widely used as a surrogate measure of adiposity, it is a measure of excess weight, rather than excess body fat, relative to height. The BMI classification system is derived from cut points obtained from the general population. The influence of large muscle mass on BMI in athletes and young adults may misclassify these individuals as overweight and obese. Therefore, the use of subcutaneous adipose tissue topography (SAT-Top) may be more effective than BMI in assessing obesity in physically active people and young adults. The purposes of this study were 1) to describe the relationship between the BMI and SAT-Top of young athletes and nonathletes, and 2) to determine the accuracy of the BMI as a measure of overweight. Height, weight, BMI and SAT-Top were determined in 64 males (25.0 +/- 6.7) and 42 females (24.8 +/- 7.0), who were subsequently separated into two even groups (athletes and non-athletes). The optical Lipometer device was applied to measure the thickness of subcutaneous adipose tissue (SAT). While BMI was similar, male athletes showed a 50.3% lower total SAT thickness compared to their male nonathlete controls. Even though female athletes had significantly higher BMI and weight scores, their total SAT thickness was 34.9% lower than their nonathlete controls. These results suggest subcutaneous fat patterns are a better screening tool to characterize fatness in physically active young people.

Primary epiploic appendagitis and successful outpatient management.

BACKGROUND: Primary epiploic appendagitis (PEA) is a rare cause of abdominal acute or subacute complaints. Diagnosis of PEA is made with ultrasonography (US) or when computed tomography (CT) reveals a characteristic lesion. CASE REPORT: We report on two patients with PEA. In one patient PEA was first seen with US and confirmed with contrast enhanced CT, and in the second patient CT without contrast enhancement demonstrated PEA. In both patients an outpatient recovery with conservative non-surgical treatment is described. CONCLUSIONS: Medical personnel should be aware of this rare disease, which mimics many other intra-abdominal acute and subacute conditions. A correct diagnosis of PEA with imaging procedures enables conservative and successful outpatient management avoiding unnecessary surgical intervention and additional costs.

Decrease of total subcutaneous adipose tissue from infancy to childhood.

OBJECTIVES: The observation and research of body composition is a topic of present interest. For the assessment of health and variables influencing growth and nutrition, it is of utmost interest to focus on the population of young children. SUBJECTS AND METHODS: The measurements of subcutaneous body fat distribution in a sample of clinically healthy children ages 0 to 7 years were examined. The optical device LIPOMETER was applied to measure the thickness of subcutaneous adipose tissue layers (in millimeters) at 15 well-defined body sites. This set of measurement points defines the subcutaneous adipose tissue topography. In the present study, subcutaneous adipose tissue topography was determined in 275 healthy children (128 girls and 147 boys) divided into 3 age groups. RESULTS: The results of the measurements are presented in 3 levels: total subcutaneous adipose tissue, 4 body regions, and 15 body sites. Our results show a clear physiological decrease in subcutaneous body fat in boys (-43.8%) and girls (-39.8%). One interesting finding was that the decrease occurs mainly in the trunk, abdomen, and lower extremities, whereas the body fat distribution of the upper extremities did not differ. Furthermore, slight subcutaneous adipose tissue topography differences between both sexes were found. CONCLUSIONS: The present study provides basic documentation of subcutaneous adipose tissue topography in healthy children ages 0 to 7 years. An accurate description of subcutaneous adipose tissue topography in healthy subjects could help to characterize various diseases in relation to overnutrition and malnutrition throughout childhood.

The acute effect of ingesting a quercetin-based supplement on exercise-induced inflammation and immune changes in runners.

This study tested the acute anti-inflammatory and immune-modulating influence of a quercetin-based supplement consumed by endurance athletes 15 min before an intense 2-hr run. In this randomized, crossover study, 20 runners (11 men, 9 women, age 38.4 ± 2.1 yr) completed two 2-hr treadmill runs at 70% VO(2max) (3 wk apart). Subjects ingested either 4 quercetin-based chews (Q-chew) or placebo chews (PL) 15 min before the runs. The 4 Q-chews provided 1,000 mg quercetin, 120 mg epigallocatechin 3-gallate, 400 mg isoquercetin, 400 mg each eicosapentaenoic acid and docosahexaenoic acid, 1,000 mg vitamin C, and 40 mg niacinamide. Subjects provided blood samples 30 min before, immediately after, and 1 hr postexercise and were analyzed for plasma quercetin, total blood leukocytes (WBC), C-reactive protein (CRP), 9 cytokines (IL-6, TNFα, GM-CSF, IFNγ, IL-1ß, IL-2, IL-8, IL-10, and IL-12p70), granulocyte (GR) and monocyte (MO) phagocytosis (PHAG), and oxidative-burst activity (OBA). Plasma quercetin increased from 80.0 ± 26.0 µg/L to 6,337 ± 414 µg/L immediately postexercise and 4,324 ± 310 µg/L 1 hr postexercise after ingestion of Q-chews, compared with no change in PL (p < .001). Exercise caused significant increases in, CRP, GM-CSF, IL-10, IL-1ß, IL-2, IL-6, IL-8, TNFα, GR-PHAG, and MO-PHAG and decreases in GR-OBA and MO-OBA, but no differences in the pattern of change were measured between Q-chew and PL trials. Acute ingestion of Q-chews 15 min before heavy exertion caused a strong increase in plasma quercetin levels but did not counter postexercise inflammation or immune changes relative to placebo.

Effects of a hyperbaric environment on subcutaneous adipose tissue topography (SAT-top).

The physiological reactions of the body in scuba diving situation can be simulated in a pressure chamber by increasing the ambient pressure. In this study the influence of a hyperbaric environment of 6 bar on the changes of the subcutaneous adipose tissue (SAT) thicknesses on different body sites in 68 voluntary men with undersea diving experience was investigated. Measurements of SAT-topography (SAT-Top) were performed with the optical device Lipometer before and after hyperbaric exposure. We observed a significant increase of the SAT-layers of the upper body zones, upper abdomen (+24.5%), lower abdomen (+21%) and front chest (+19%) after hyperbaric exposure. This increase of volume can be assumed to the nitrogen accumulation in fat cells at increased ambient pressures. In conclusion we describe for the first time in detail the influence of a hyperbaric environment on quantitative and topographic changes of SAT.

Influence of Spiritual Dimensions on Suicide Risk: The Role of Regional Differences.

The field of suicide prevention has been enriched by research on the association between spirituality and suicide. Many authors have suggested focusing on the various dimensions of religiosity in order to better understand the association between religion and suicidal risk, but it is unclear whether the relationship between spirituality and suicidality differs between countries with different cultures, life values, and sociohistorical experiences. To explore this, the aim of this multicenter study was to investigate the possible relationship between suicide and spirituality in Italy and Austria. In the two countries, two different groups of subjects participated: psychiatric patients and university students. The patients were evaluated with the Mini International Neuropsychiatric Interview. In addition, the following measures were used: a sociodemographic questionnaire, the Columbia-Suicide Severity Rating Scale-B, the Symptom-Checklist-90-Standard, and the Multidimensional Inventory for Religious/Spiritual Well-Being. Our results confirmed the multifactorial nature of the relation between suicide risk and the various religious/spiritual dimensions, including religious/spiritual well-being and hope immanent. However, regional differences moderated this relationship in both the clinical and nonclinical samples.

Estimating DXA total body fat percentage by lipometer subcutaneous adipose tissue thicknesses.

DXA is an accepted reference method to estimate body composition. However several difficulties in the applicability exist. The equipment is rather expensive, not portable, impractical for measurement of big study populations and it provides a minimal amount of ionizing radiation exposure. The optical device Lipometer (EU Pat.No. 0516251) provides non-invasive, quick, precise and safe measurements of subcutaneous adipose tissue (SAT) layer thicknesses at any site of the human body. Compared to DXA there are some advantages in the Lipometer approach, because this device is portable, quick, not expensive and no radiation is involved. To use these advantages in the field of total body fat% (TBF%) assessment, an acceptable estimation of DXA TBF% by Lipometer SAT thicknesses is necessary, which was the aim of this study. Height, weight, waist and hip circumferences, DXA TBF% and Lipometer SAT thicknesses at fifteen defined body sites were measured in 28 healthy men (age: 33.9 +/- 16.6 years) and 52 healthy women (age: 40.1 +/- 10.7 years). To estimate Lipometer TBF% stepwise multiple regression analysis was applied, using DXA TBF% as dependent variable. Using the fifteen Lipometer SAT thicknesses together with age, height, weight and BMI as independent variables provided the best estimations of Lipometer TBF% for both genders with strong correlations to DXA TBF% (R = 0.985 for males and R = 0.953 for females). The limits of agreement were -2.48% to +2.48% for males and -4.28% to + 4.28% for females. For both genders we received a bias of 0.00%. The results of this paper extend the abilities of the Lipometer by a precise estimation of TBF% using DXA as golden standard.

Is the molecular clock ticking differently in bipolar disorder? Methylation analysis of the clock gene ARNTL.

OBJECTIVES: The clock gene ARNTL is associated with the transcription activation of monoamine oxidase A according to previous literature. Thus, we hypothesised that methylation of ARNTL may differ between bipolar disorder (BD) and controls. METHODS: The methylation status of one CpG island covering the first exon of ARNTL (PS2) and one site in the 5' region of ARNTL (cg05733463) were analysed in patients with BD (n = 151) versus controls (n = 66). Methylation analysis was performed by bisulphite-conversion of DNA from fasting blood with the EpiTect Bisulfite Kit, PCR and pyrosequencing. Analysis of covariances considering the covariates age, body mass index, sex, smoking, lithium and anticonvulsant intake were performed to test methylation differences between BD and controls. RESULTS: Methylation at cg05733463 of ARNTL was significantly higher in BD than in controls (F(1,209) = 44.500, P < .001). In contrast, methylation was significantly lower in BD at PS2_POS1 compared to controls (F(1,128) = 5.787, P = .018) and by trend at PS2_POS2 (F(1,128) = 3.033, P = .084) and POS7 (F(1,34) = 3.425, P = .073). CONCLUSIONS: Methylation of ARNTL differed significantly between BD and controls. Thus, our study suggests that altered epigenetic regulation of ARNTL might provide a mechanistic basis for better understanding circadian rhythms and mood swings in BD.

Long-Term Weight-Loss Maintenance by a Meal Replacement Based Weight Management Program in Primary Care.

OBJECTIVE: Structured obesity treatment programs at primary care level are becoming increasingly important. However, evidence from current treatment approaches in the long term is lacking. In view of this fact we evaluated a standardized, meal replacement-based weight loss program (myLINE®; AENGUS, Graz, Austria) according to the currently applicable guidelines. METHODS: Data of overweight and obese individuals (n = 70) who participated at least 36 months in the program were analyzed. Data were collected at baseline (T0) as well as after 1, 3, 6, 12, 24, and 36 (T1-T36) months. Body composition was measured by conventional anthropometry and bioelectrical impedance analysis. RESULTS: Compared to T0, a maximum weight, BMI, fat mass, absolute body cell mass (BCM) reduction and an increase of relative BCM could be seen at T6. Subsequently, the findings reveal a significant reduction of body weight and body fat and a satisfying development of body cell mass during the observation period of 36 months. CONCLUSION: The evaluated program complies with national and international guidelines for the therapy of obesity in adults and is efficient and meaningful for a long-term therapeutic use in primary care..

Dissimilar Pain of Primary Epiploic Appendagitis and Malabsorption.

Primary Epiploic Appendagitis (PEA) is a rare cause of acute or subacute abdominal complaints and non-migratory pain. Usually the diagnosis of PEA is made when Computed Tomography (CT) reveals characteristic figures. Nonspecific abdominal complaints including diffuse abdominal pain may be caused by carbohydrate and/or protein malabsorption. We report a case of a patient with PEA who recovered without medication or surgical treatment within a few days. Eight months later, he was diagnosed with lactose- and histamine malabsorption and Helicobacter pylori infection. The malabsorption was treated successfully with an individually-tailored diet free of culprit triggers and the Helicobacter pylori infection was eradicated. A localized non-migratory abdominal pain caused by PEA needs to be differentiated from nonspecific abdominal complaints due to malabsorption and Helicobacter pylori infection.

Endoplasmic Reticulum Stress and Bipolar Disorder - Almost Forgotten Therapeutic Drug Targets in the Unfolded Protein Response Pathway Revisited.

Bipolar Disorder (BD) is characterized by recurring mood swings, which are not completely understood yet. So far, it is an accepted theory that multiple factors contribute to pathogenesis of BD according to the vulnerability-stressmodel. This model combines on the one hand biological predisposing vulnerability, and on the other hand several chronic and acute stressful negative events as underlying mechanisms of BD. Recently, ER (Endoplasmic Reticulum) stress reached the spotlight of BD research again. The expression of the chaperone BiP (syn. GRP78/glucose-regulated protein, 78kDa), which is highly expressed in the Endoplasmic Reticulum (ER), is upregulated by different kinds of mood stabilizers. These results implied that the ER, an organelle which is prone towards different kinds of cellular stress, might be involved in the pathophysiology of BD. This hypothesis was further strengthened by hypothesis driven genetic association studies, which showed significant association of BiP promotor polymorphisms with BD. Also other ER-stress associated genes like XBP1 (X-box binding protein 1) or GRP94 (glucose-regulated protein, 94kDa, synonym for heat shock protein HSP90B1) were recently linked to BD in hypothesis driven gene association studies. In addition to the proteins mentioned before, our review focuses on further UPR (Unfolded Protein Response) related proteins associated with BD and raises the hypothesis that ER-stress may represent a common interface between BD and obesity which is overrepresented in BD patients. Finally, members of the UPR pathway are discussed as putative targets for mood stabilizers.

The Effectiveness of Visual Short-Time Neurofeedback on Brain Activity and Clinical Characteristics in Alcohol Use Disorders: Practical Issues and Results.

The present study was carried out to examine the efficacy of alpha/theta neurofeedback (NF) with a new visual paradigm in a cohort of alcohol use disordered (AUD) patients (n = 25) treated in an Austrian therapeutic community center. The experimental study design focused on changes in absolute and relative resting EEG band power as well as in clinical variables, including depression (Beck Depresion Inventory [BDI-V]), psychiatric symptoms (Brief Symptom Inventory [BSI], coping (Freiburg Questionnaire on Coping with Illness [FKV-lis]), psychotherapy motivation (Therapy Motivation Questionnaire [FPTM-23]), sense of coherence (Sense of Coherence Scale [SOC-13]), posttraumatic growth (Posttraumatic Growth Inventory [PPR]), and alcohol cravings (Alcohol Craving Questionnaire [ACQ]). For measuring training effects, participants were randomly allocated to 2 groups: an experimental group (EG, n = 13) and a control group (CG, n = 12). Patients in EG received 12 sessions of visual NF training over a period of 6 weeks to enhance alpha (8-12 Hz) and theta (4-7 Hz) frequency band power in addition to the standard treatment program of the rehabilitation center. Participants in CG received no additional NF intervention. The multivariate analysis of covariance (MANCOVA) showed a change by trend in absolute alpha and theta power in the EG. Even though no MANCOVA effects were found in the clinical scales, AUD patients reported increasing control of their brain activity during the course of NF. However, changes in several clinical scales (BDI-V, BSI, FKV-lis, PPR) from pre- to posttest were observed only in the EG contrary to the CG. The findings of this pilot study provide first evidence for the practicality and effectiveness of visual short-term NF as an additive intervention in the therapeutic community.
