A Prospective Observational Pilot Study on the Effects of the Activity-Based Stress Release Program on the Mental State and Autonomic Nervous System in Psychiatric Patients.

BACKGROUND: In our pilot study, we investigated the psychological (well-being and personal coping strategies) and physiological (assessed by heart rate variability (HRV)) effects of the newly developed activity-based stress release (ABSR) program for people with depressive disorders, also in combination with burnout symptoms and/or anxiety disorders. METHODS: A single-arm prospective observational study was carried out. Twenty participants diagnosed with depression and burnout or anxiety disorders were invited to participate in the 8-week ABSR program. All participants filled in two questionnaires (the multidimensional mental state questionnaire and the Ehrenfeld inventory on coping style) before, directly after and 2 months after the 8-week ABSR program. In addition, all participants were offered a 24-hour Holter ECG measurement before, directly after and 2 months after the 8-week ABSR program to measure HRV. RESULTS: Calmness and serenity showed a statistically significant improvement after the 8-week ABSR program. However, complete questionnaire sets were not available from all of the participants. In the four individuals who had agreed to a 24-hour Holter ECG, the overall HRV and parasympathetic activity increased. CONCLUSIONS: The ABSR program is an encouraging novel therapeutic approach: A significant improvement in calmness and serenity was observed after ABSR. A larger and controlled trial of this treatment option in depression and burnout is recommended. It should be further investigated how ABSR affects task-evoked and resting brain activity, and what effects it has on the cardiovascular system in general (better blood flow and normalization of activity are to be expected).

Phytotherapy in paediatric skin disorders - A systematic literature review.

OBJECTIVES: Although skin disorders in children and adolescents are increasingly treated with phytotherapies in practice, there are very few studies investigating this topic, and no systematic review exists that summarizes the current state of research. This review examines which herbal medicines show to be effective to treat atopic dermatitis, diaper dermatitis, and skin lesions or wounds. METHODS: Clinical studies were searched according to PRISMA-guidelines in the medical databases of PubMed, EMBASE, and CINAHL and summarised in a systematic review. RESULTS: Among the 429 articles screened, 17 studies with a total of 2358 participants were identified that suited our inclusion criteria. Thereof seven studies each on the treatment of atopic dermatitis and skin lesions or wounds and three on diaper dermatitis. The phytotherapeutics investigated were based on the following herbs: Evening primrose, blackcurrant, polypodium leucotomos, calendula, aloe vera, chamomile, comfrey, hamamelis, olive, hypericum, neem, white oak, and myrrh. They have mainly been analysed in randomized controlled trials, but also in (long-term) observational studies, prospective trials and case series. CONCLUSIONS: Based on the application of the Jadad score, eight out of 17 of the studies examined were of low quality. Yet we found some indication that evening primrose oil may be effective for treating atopic dermatitis in children, while comfrey appears to have a positive effect on wound healing. Interestingly, none of the studies found positive effects for treating skin disorders with aloe vera or chamomile.

Treatment of hyperemesis gravidarum with anthroposophic complex therapy in 3 case reports.

BACKGROUND: Hyperemesis gravidarum (HG) is generally characterized by intractable nausea and vomiting which interferes with daily life. As the cause of HG has not yet been clearly identified, conventional medicine therapies address only the symptoms. Conventional treatment is also effective for a comparatively short time and may have unfavorable side effects. Given that the condition affects more than 1% of pregnant women, there is a significant need for effective long-lasting treatments with limited side effects. CASE REPORTS: This paper is based on three case reports of pregnant women suffering from HG. They received inpatient treatment based exclusively on anthroposophic medical approaches at the Paracelsus Hospital Richterswil, Switzerland. Treatments were selected individually based on the specific patient profiles and included infusion therapy with Nux vomica, Solum uliginosum compositum and Bryophyllum pinnatum as well as art therapy (wet-on-wet painting), eurythmy therapy and rhythmical massage therapy. Anthroposophic complex therapies induced an improvement in symptoms of nausea and vomiting within one week in all three cases. CONCLUSION: Anthroposophic complex therapy is a valuable option in the treatment of HG. Well-tolerated and long-lasting, it represents a holistic and causal approach that does not only address symptoms.

Heart Rate Variability as a Prognostic Factor for Cancer Survival - A Systematic Review.

An increasing cancer incidence affecting any age and social class is putting serious strain on populations and health care systems around the world. This systematic literature search aims (i) to examine the correlation of heart rate variability (HRV) and cancer patients' prognosis, (ii) to examine the relationship of HRV and clinicopathological features, and (iii) to compare HRV between different patient groups, and between patient and control groups. We conducted a systematic literature review following the PRISMA Statement. We searched the PubMed and EMBASE databases for publications released by December 2017. The search terms were: "cancer" AND "heart rate variability" AND "human" NOT "animal" NOT "review." A total of 19 studies were finally included in this review. Most publications were high-quality observational studies. The studies showed that higher HRV correlated positively with patients' progression of disease and outcome. Thus, we conclude that individuals with higher HRV and advanced coping mechanisms seem to have a better prognosis in cancer progression. HRV appears to be a useful aspect to access the general health status of cancer patients.

Neural coupling of cooperative hand movements: a reflex and fMRI study.

The neural control of "cooperative" hand movements reflecting "opening a bottle" was explored in human subjects by electromyographic (EMG) and functional magnetic resonance imaging (fMRI) recordings. EMG responses to unilateral nonnoxious ulnar nerve stimulation were analyzed in the forearm muscles of both sides during dynamic movements against a torque applied by the right hand to a device which was compensated for by the left hand. For control, stimuli were applied while task was performed in a static/isometric mode and during bilateral synchronous pro-/supination movements. During the dynamic cooperative task, EMG responses to stimulations appeared in the right extensor and left flexor muscles, regardless of which side was stimulated. Under the control conditions, responses appeared only on the stimulated side. fMRI recordings showed a bilateral extra-activation and functional coupling of the secondary somatosensory cortex (S2) during the dynamic cooperative, but not during the control, tasks. This activation might reflect processing of shared cutaneous input during the cooperative task. Correspondingly, it is assumed that stimulation-induced unilateral volleys are processed in S2, leading to a release of EMG responses to both forearms. This indicates a task-specific neural coupling during cooperative hand movements, which has consequences for the rehabilitation of hand function in poststroke patients.

Obstacle avoidance locomotor tasks: adaptation, memory and skill transfer.

The aim of this study was to explore the neural basis of adaptation, memory and skill transfer during human stepping over obstacles. Whilst walking on a treadmill, subjects had to perform uni- and bilateral obstacle steps. Acoustic feedback information about foot clearance was provided. Non-noxious electrical stimuli were applied to the right tibial nerve during the mid-stance phase of the right leg, i.e. 'prior' to the right or 'during' the left leg swing over the obstacle. The electromyogram (EMG) responses evoked by these stimuli in arm and leg muscles are known to reflect the neural coordination during normal and obstacle steps. The leading and trailing legs rapidly adapted foot clearance during obstacle steps with small further changes when the same obstacle condition was repeated. This adaptation was associated with a corresponding decrease in arm and leg muscle reflex EMG responses. Arm (but not leg) muscle EMG responses were greater when the stimulus was applied 'during' obstacle crossing by the left leg leading compared with stimulation 'prior' to right leg swing over the obstacle. A corresponding difference existed in arm muscle background EMG. The results indicate that, firstly, the somatosensory information gained by the performance and adaptation of uni- and bilateral obstacle stepping becomes transferred to the trailing leg in a context-specific manner. Secondly, EMG activity in arm and leg muscles parallels biomechanical adaptation of foot clearance. Thirdly, a consistently high EMG activity in the arm muscles during swing over the obstacle is required for equilibrium control. Thus, such a precision locomotor task is achieved by a context-specific, coordinated activation of arm and leg muscles for performance and equilibrium control that includes adaptation, memory and skill transfer.

Locomotion in stroke subjects: interactions between unaffected and affected sides.

The aim of this study was to evaluate the sensorimotor interactions between unaffected and affected sides of post-stroke subjects during locomotion. In healthy subjects, stimulation of the tibial nerve during the mid-stance phase is followed by electromyography responses not only in the ipsilateral tibialis anterior, but also in the proximal arm muscles of both sides, with larger amplitudes prior to swing over an obstacle compared with normal swing. In post-stroke subjects, the electromyography responses were stronger on both sides when the tibial nerve of the unaffected leg was stimulated compared with stimulation of the affected leg. This difference was more pronounced when stimuli were applied prior to swing over an obstacle than prior to normal swing. This indicates an impaired processing of afferent input from the affected leg resulting in attenuated and little task-modulated reflex responses in the arm muscles on both sides. In contrast, an afferent volley from the unaffected leg resulted in larger electromyography responses, even in the muscles of the affected arm. Arm muscle activations were stronger during swing over an obstacle than during normal swing, with no difference in electromyography amplitudes between the unaffected and affected sides. It is concluded that the deficits of the affected arm are compensated for by influences from the unaffected side. These observations indicate strong mutual influences between unaffected and affected sides during locomotion of post-stroke subjects, which might be used to optimize rehabilitation approaches.
